After the Tunisian revolution, people were hit by the bitter reality of the Tunisian miracle of Ben Ali's regime: an unemployment rate of 20% (INS [2013]) and a poverty rate reaching 25%. With no access to loans, low-income people find themselves in a vicious circle of poverty that will lead them to either begging or criminality. Many of the country's poor people carry heavy life baggage; the stories of their personal life lives could have been ripped from the pages of Les Misérables. Such realities pushed the government to make draconian changes leading to more liberalization of the microfinance sector, in an attempt to alleviate poverty and enhance social inclusion. Among the new players allowed into the market are private equity (PE) firms. The decision to allow PE participation caught the industry by surprise, since the Tunisian microfinance sector had always been restricted to nonprofit associations, far from the reach of PE firms. The change gave rise to numerous questions: Why would a private equity firm invest in the micro-finance sector? Why now? Is the sector profitable? Is it competitive? What is the investment strategy?


Whereas deep neural networks were first mostly used for classification tasks, they are rapidly expanding in the realm of structured output problems, where the observed target is composed of multiple random variables that have a rich joint distribution, given the input. In this paper we focus on the case where the input also has a rich structure and the input and output structures are somehow related. We describe systems that learn to attend to different places in the input, for each element of the output, for a variety of tasks: machine translation, image caption generation, video clip description, and speech recognition. All these systems are based on a shared set of building blocks: gated recurrent neural networks and convolutional neural networks, along with trained attention mechanisms. We report on experimental results with these systems, showing impressively good performance and the advantage of the attention mechanism.


We apply a phase retrieval algorithm to the intensity pattern of a Hartmann wavefront sensor to measure with enhanced accuracy the phase structure of a Hartmann hole array. It is shown that the rms wavefront error achieved by phase reconstruction is one order of magnitude smaller than the one obtained from a typical centroid algorithm. Experimental results are consistent with a phase measurement performed independently using a Shack-Hartmann wavefront sensor.


Modeling dependencies among features is fundamental for many machine learning tasks. Although there are often multiple related instances that may be leveraged to inform conditional dependencies, typical approaches only model conditional dependencies over individual instances. In this work, we propose a novel framework, partially observed exchangeable modeling (POEx) that takes in a set of related partially observed instances and infers the conditional distribution for the unobserved dimensions over multiple elements. Our approach jointly models the intra-instance (among features in a point) and inter-instance (among multiple points in a set) dependencies in data. POEx is a general framework that encompasses many existing tasks such as point cloud expansion and few-shot generation, as well as new tasks like few-shot imputation. Despite its generality, extensive empirical evaluations show that our model achieves state-of-the-art performance across a range of applications.


Background After an aeroplane crash, recovery of the 'black box' is a high priority for investigators; analysis of recorded parameters frequently identifies cause or contributing factors. The placenta likewise provides an invaluable record of the pre-'crash' period in hypoxic ischaemic encephalopathy (HIE); its examination often identifies significant factors such as inflammation or vasculopathy. Objective To determine the frequency of histopathologic placental examination and chorioamnionitis in a high-risk population of encephalopathic newborns. Methods We studied neonates ≥36 weeks' gestation admitted with HIE to three tertiary-level UK centres between 01/07/06 and 30/06/11. We assessed if placental histopathological examination was carried out and if there was evidence of chorioamnionitis and/or funisitis. Results 305 infants were admitted with HIE in the 5-year study period. Placental data were unavailable for 140 outborn infants. Only 50/165 (30%) inborn babies had placentas submitted to pathology. Histopathological examination confirmed chorioamnionitis and/or funisitis in 16/50 (32%) cases. Conclusion Placental examination serves several vital roles in babies born with suspected HIE: it defines pathophysiology, provides important prognostic information regarding future neurodevelopmental outcome, and shows mitigating factors of medicolegal relevance to causation of brain injury. Intrapartum infection and chorioamnionitis are associated with poor neonatal outcomes including cerebral palsy. Only 30% placentas were examined in our tertiary centres, yet those examinations showed a high incidence of chorioamnionitis. The low rate of placentas being submitted for examination in neonates born depressed, coupled with the high incidence of proven chorioamnionitis in those submitted, is of great concern.


Spawning sites are a critical and often scarce resource for aquatic-breeding amphibians, including invasive species such as the cane toad (Bufo marinus). If toads select spawning sites based on habitat characteristics, we can potentially manipulate those characteristics to either enhance or reduce their suitability as breeding sites. We surveyed 25 spawning sites used by cane toads, and 25 adjacent unused sites, in an area of tropical Australia recently invaded by these feral anurans. Water chemistry (pH, conductivity, salinity, turbidity) was virtually identical between the two sets of waterbodies, but habitat characteristics were very different. Toads selectively oviposited in shallow pools with gradual rather than steep slopes, and with open (unvegetated) gradually sloping muddy banks. They avoided flowing water, and pools with steep surrounds. In these respects, cane toads broadly resemble previously studied toad species in other parts of the world, as well as conspecifics within their natural range in South America.


This case study investigates the potential impact of privatisation on the financial performance of infrastructure State Owned Enterprises (SOEs) in the Middle East and North Africa (MENA) region. It considers initiatives taken in Tunisia, Morocco, Saudi Arabia, and Jordan between 1988 and 2003. The financial performance is assessed in terms of profitability, operating efficiency, capital expenditures, leverage and financial risk levels, cost of labour and share prices. The results show that post-privatisation financial results depend on the pre-privatisation status of the SOEs, as well as on various reforms considered in its economic environment. Sales, labour efficiency, and labour costs improved post-privatisation. Moreover, profitability levels increased in only 40% of the considered sample. Percentage changes in the share price surpassed the percentage changes in the market indices in some countries, but not in every country. Capital expenditure levels were stable compared to pre-privatisation levels. Additionally, debt and credit risk levels decreased post-privatisation. Finally, the study reports that managerial restructuring has the potential to generate the same (and even better in some areas) results as privatisation, but this do not mean that state ownership is optimal in the long run. The overall conclusion is that privatising infrastructure SOEs is optimal in the MENA region but should be preceded by managerial and financial reforms in order for it to lead to optimal economic results and to allow for financial performance improvements to appear.


Video transmission in wireless environments is a challenging task calling for high compression efficiency as well as a network friendly design. These have been major goals of the H.264/AVC standardization effort addressing "conversational" (i.e., video telephony) and "non-conversational" (i.e., storage, broadcast, or streaming) applications. The video compression performance of the H.264/AVC Video Coding Layer typically provides a significant improvement. The network-friendly design goal of H.264/AVC is addressed via the Network Abstraction Layer that has been developed to transport the coded video data over any existing and future networks including wireless systems. The main objective of this paper is to provide an overview over the tools which are likely to be used in wireless environments and discusses the most challenging application, wireless conversational services in greater detail. Appropriate justifications for the application of different tools based on experimental results are presented.


Brass is known for excellent machinability, but its ultimate productivity potential with high speed machining requires further study. An extensive testing program was conducted in laboratory and production settings on representative brass rod alloys using modern machine tools. Machinability data collected for turning, drilling and milling offers new insights on the effects of increasing speed, feed rate and depth of cut on tool life, efficiency, surface integrity and chip formation. The results show that advancements in machine tool technology, coupled with the underutilized high speed machining capabilities of brass, offer new opportunities for manufacturers to become more productive and profitable.


This book gives a step-by-step presentation of a generalized transmission line method to study the far-zone radiation of antennas under a multilayer structure. Normally, a radiation problem requires a full wave analysis which may be time consuming. The beauty of the generalized transmission line method is that it transforms the radiation problem for a specific type of structure, say the multilayer structure excited by an antenna, into a circuit problem that can be efficiently analyzed. Using the Reciprocity Theorem and far-field approximation, the method computes the far-zone radiation due to a Hertzian dipole within a multilayer structure by solving an equivalent transmission line circuit. Since an antenna can be modeled as a set of Hertzian dipoles, the method could be used to predict the far-zone radiation of an antenna under a multilayer structure. The analytical expression for the far-zone field is derived for a structure with or without a polarizer. The procedure of obtaining th Hertzian dipole model that is required by the generalized transmission line method is also described. Several examples are given to demonstrate the capabilities, accuracy, and efficiency of this method.

An improved 12-step synthetic route and full characterization of hexaphenyl-carbo-benzene (4, 8%) and the p-bis-3,5-di-tert-butylphenyl homologue (11, 4%), are described. The carbo-benzene reference 4 is now accurately described in the crystal state by X-ray diffraction analysis in the chiral space group P212121, and in comparison to the less symmetric derivative 11 exhibiting a centro-symmetric packing. According to cyclic voltammetry, both hexaaryl-carbo-benzenes 4 and 11 can behave as both reversible potent electron acceptors and standard electron donors, with respective potentials of −0.73 ± 1 V and +1.17 ± 2 V/SCE, respectively. Due to their extremely low solubility, solid films of 11 fabricated using the "wet method", with the initial view of studying charge transport properties, were found to display high roughness.


Background Concussion poses a challenge to sports medicine personnel, especially those working in contact sports such as football. In disability sport, the correct assessment and management of this injury is paramount. Objective To determine knowledge, attitudes, and beliefs regarding concussion amongst team physicians/physiotherapists working at the 2015 Cerebral Palsy Football World Championships (CPFWC). Design A 22-item questionnaire was provided to the 'head of medicine' of all teams participating at the 2015 CPFWC (n=15). Qualitative assessment of knowledge, attitudes and beliefs of participants in regard to concussion; both generally, and specifically to cerebral palsy football. Setting 2015 CPFWC, St George's Park, Burton-upon-Trent, United Kingdom. Patients (or Participants) Each nation's head of medical services (n=15; either a medical doctor or physiotherapist) were invited to complete the questionnaire during the pre-competition medical meeting. Interventions (or Assessment of Risk Factors) NA. Main Outcome Measurements Knowledge, attitudes, and beliefs related to concussion amongst sports medicine professionals at a World Championship. Results The majority of participants (8 physiotherapists and 6 doctors: or 93%) completed the questionnaire. Only one practitioner did not score 100% on identifying the signs and symptoms of concussion. 36% (n=5) believed headgear had protective effects against concussion. The use of a concussion assessment tool following suspected concussion was reported by 29% (n=4) clinicians, whilst 50% (n=7) stated that performing cognitive assessments were difficult in this population. 86% participants (n=12) reported that a disability sport concussion consensus statement would be useful. Conclusions Participants' overall knowledge around concussion was sound, but their methods for recognition and management were highly variable. Inherent difficulties were identified in the assessment and management of concussion in disabled athletes and the majority recognised an urgent need for expert clinical guidance for this population.

Soft skills are a crucial component for success in today's workplace as employers increasingly value work that is collaborative and encompasses diverse perspectives. Despite this, most engineering programs fail to explicitly teach students transferable skills, including the best practices of group work. This research sought to explore how undergraduate experiences of group work change over time. This research also investigated what reflecting on cooperative education (co-op) experiences tells us about teaching group work in academic settings. Despite frequently noting the influence of group work in developing their communication skills and brainstorming ideas over time, students become somewhat more frustrated over time with their experiences of group work, mainly due to conflicting personalities and ideas among team members and/or a "slacker" student. However, our findings also show that students become more confident working in teams over time, as upper-year students were more likely to assume a leadership role and self-reported higher past performance as a group member. This study offers insights into the changing group work experiences of undergraduate engineering students as they progress through coursework and engage in experiential learning and work-integrated learning opportunities, such as co-op placements. The findings of this study can inform educators on how to best incorporate methods for teaching transferable soft skills.


While under the common law judges presumed that most defendants would be released on bail before trial, now only some defendants are guaranteed pretrial release. Historically, due process and the presumption of innocence guaranteed criminal defendants the right to release before trial unless there was a serious risk of flight. The evolution of bail law has rendered this former guarantee meaningless. Now judges use various factors to determine release based on a prediction of whether the defendant is guilty and how dangerous he will be if released pretrial. Two problems result from the new "predictive" state of pretrial detention: 1) the failure of judges to accurately predict which defendants pose a threat to the community and 2) over-detention of defendants that can safely be released.This chapter discusses a few solutions to dealing with the new state of predictive justice. While ideally judges would return to common law notions and presume bail for most defendants, this is unlikely with the state of federal and state statutory law. Given the legal reality, there are two recent approaches that address the problem of excessive pretrial detention and prejudice resulting for defendants incarcerated pretrial. First, judges could rely on empirical methods to better predict which defendants will commit crimes while on release. Using this evidence-based approach, judges could look at county-specific data and safely release more defendants, according to a recent study. Second, targeting a budget-conscious public, states and local governments can increase pretrial release supervision programs by demonstrating that it is less costly and sometimes even safer for the public. By incorporating alternatives to detention and increasing pretrial release programs, some states have shown that they can reduce the costs of the pretrial detention system, reduce pretrial crime, and eliminate the prejudice defendants often face with detention. Part I of this chapter overviews the history and evolution of the U.S. system of predictive justice pretrial. Without an understanding of historical expectations that guaranteed bail for most defendants, it is difficult to understand how limited our current notions of pretrial release are and how current U.S. law has abandoned basic due process protections. Part II discusses the problems with past judicial predictions of pretrial crime and demonstrates how judges can release more defendants safely with empirical modeling. Using evidence-based modeling of county-specific data, according to a recent study, judges can release up to 25% more defendants while reducing overall pretrial crime. Part III discusses the new wave of bail reform, including a discussion of the American Bar Association (ABA) Standards on Pretrial Release. This part discusses how some states implementing reforms in line with these standards have increased pretrial release supervision programs by emphasizing fiscal responsibility. Demonstrating that pretrial release programs cost the public less than incarceration and better protect defendants' rights is another way to increase pretrial release while maintaining community safety.


The relationship of the computer user to the system and to the information gained is a subtle one, and in organizations many different types of relationship are possible. Previous definitions of "user' and "end-user" emphasize direct interactive forms of computer use and do not cover indirect relationships; they also do not take into consideration the reason for the interaction. A new definitional framework is required which encompasses the different modes and purposes of IS users. This paper proposes a two-dimensional typology which employs an association dimension and a purpose dimension in order to identify the nature of the relationships more accurately. The association dimension indicates how close the user is to the information source; the purpose dimension indicates what the user does with the information. The new typology will help to clarify the subtle and changing relationships between computer users, systems and IS support staff.


Auxin influences all aspects of plant growth and development and exerts its function at scales ranging from the subcellular to the whole-organism level. A canonical mechanism for auxin signaling has been elucidated, which is based on derepression of downstream genes via ubiquitin-mediated degradation of transcriptional repressors. While the combinatorial nature of this canonical pathway provides great potential for specificity in the auxin response, alternative noncanonical signaling pathways required to mediate certain processes have been identified. One such pathway affects gene regulation in a manner that is reminiscent of mechanisms employed in animal hormone signaling, while another triggers transcriptional changes through auxin perception at the plasma membrane and the stabilization of transcriptional repressors. In some cases, the exact perception mechanisms and the nature of the receptors involved are yet to be revealed. In this review, we describe and discuss current knowledge on noncanonical auxin signaling and highlight unresolved questions surrounding auxin biology.


Power transition theory and Graham Allison's Thucydides Trap Project are discussed in tandem with two complementary aims: to highlight theoretical and empirical contributions of the power transition research program, and to provide critical perspective on the Thucydides Trap Project. Conventional-wisdom approaches of this sort are distinguished from power transition theory, the empirical international relations theory proposed by A. F. K. Organski and further articulated and tested by generations of scholars. The theory's central elements—national power, stages of power transition, shifts in the distribution of power, international order and the status quo—are identified and discussed, with a focus on key variables used to explain war and peace among contending states. A comparative, critical examination of the Thucydides Trap Project is used as a lens for spotlighting key empirical contributions of the power transition theory research tradition and the value of adhering to norms of scientific rigor. Opportunities for further growth and development are noted, with special attention afforded to essential features of the power transition theory research program, including the study of (1) the timing and initiation of war; (2) rising powers' dissatisfaction with the status quo, and a possible distinction between dissatisfaction and revisionism; and (3) reducing the risk of violent, revisionist challenges.


Facilitated by developments in technologies, the non-consensual posting of sexually explicit images of someone else for revenge, entertainment or political motive – so called 'revenge porn' – has become a global phenomenon. This ground breaking book argues that these fundamental and recurring issues about how victims are violated can be understood in terms of gender and sexual dynamics and constructions, binary gender and sexual positioning and logics, and the use of sexual meanings.

Using a discourse analytical approach the authors examine revenge pornography through the words of the perpetrators themselves, and study the complex ways in which they invoke, and deploy, gender and sexuality-based discourses to blame the victim. They explore strategies to curb the phenomenon of revenge porn, and by placing their research in a broader social and political context, the authors are able to examine the effectiveness of current legislative frameworks, education and awareness raising, victim support, perpetrator re-education programmes, along with wider political considerations.

This enhanced understanding of the perpetrator mind set provides important insights into the use of social media to facilitate gender violence, and holds the promise of more effective interventions in future. This is a unique resource for students, academics, researchers, and professionals interested in revenge pornography and related issues


This research study is set within the national context of deteriorating sexual health. It is an attempt to discover the issues and influences behind the modelling of NHS sexual health services and what is made available to the service users. These services are having difficulty meeting the high demands of the public and achieving government targets that have been placed upon them to tackle the unprecedented rise in levels of diagnosed infection and prevent unintended conceptions. A qualitative survey of professionals and client discourse was the design for the fieldwork, consisting of interviews and focus groups of sexual health service leads, practitioners and service users, a total of 89 voices. These were analysed within a framework of feminist and complexity theory. This research exposed that the services themselves have historically experienced serious marginalisation. This has affected allocation of resources and maintained a closed shop culture, which, unless changed, allows little room for improvement. This issue is well known and yet allowed to remain hidden. The findings demonstrate that the "top to toe modernisation of the NHS", stated within the NHS plan 2000 (DH), is not greatly evident within sexual health services over 2005 to 2006, when the fieldwork was carried out. The services have not, in most cases, been redesigned around the needs of patients, access has not been improved and the roles of nurses in many services have not been extended to address these access issues, but in some cases actually blocked from doing so. The Modernisation Agency has had little effect. Service users have not felt the effect of the devolved power promised so they could have influence and service providers are not often centred on them. Attempts to improve this situation are frequently thwarted by poor strategic planning and obstruction by senior clinical staff, who fear loss of position or power. Alongside this there was evidence of insufficient workforce fit for purpose, including commissioners, key to these developments. Where services were shown to be aiming to modernise and develop integrated models of provision, this came from a strong ethos of having service users at the centre of care anda vision to improve access and quality of provision. NHS Health trusts are not allowing sexual health to be centre stage. Any improvements in services will not be sustained without a change in culture within these services themselves, as well as within the wider NHS and society generally. Investigation of theactual quality of service provision and what the public want requires a national research driver. The insider role of the researcher created opportunities to capture stories that would otherwise have been missed by an outsider. This allowed debunking or demystifying some outdated views of the functioning of sexual health service provision and the reasons for their lack of progress. The complexity theory framework gave a frame of reference for why services function the way they do, either as silo-centred or transformed. It also illustrated that forcing structural changes or service redesign, within a top down approach will not achieve a whole systems transformation. An integrated sexual health service model was demonstrated as a complex system that allowed transformation to evolve where there was success in impacting patterns of thinking, behaviour and values of the service providers. These micro-patterns allowed a rich complexity to emerge bringing positive outcomes and maybe even supporting government targets as more new patterns emerge. This was opposite to silo-centred thinking, evident in the more traditional settings. Modernisation processes and normalisation of sexual health services, alongside integration, would be assisted using complexity principles.


A Review of: Vinyard, M., Mullally, C., & Colvin, J.B. (2017). Why do students seek help in an age of DIY? Using a qualitative approach to look beyond statistics. Reference & User Services Quarterly, 56(4), 257-267. http://dx.doi.org/10.5860/rusq.56.4.257
Abstract
Objective – To explore how undergraduate students look for information and the reasons these students seek assistance from a librarian.
Design – Qualitative research.
Setting – A university in Southern California.
Subjects – 10 students were interviewed: 1 freshman, 1 sophomore, 5 juniors, and 3 seniors.
Methods – Students who met with a librarian for longer than 20 minutes were invited to participate in the study, and interviews were conducted within six weeks of this interaction. Semi-structured interviews were scheduled for one hour blocks and were audio-recorded and transcribed afterward. Interview data was analyzed using applied thematic analysis. The researchers used NVivo to assist with the process of coding data.
Main Results – Once all transcripts were coded, the researchers identified the following six themes related to how students look for information and the reasons they asked for assistance: how students research, personal perceptions of research skills, assumptions (students' misperceptions about library services), motivation for asking for help, path to the librarian (how students contacted librarians and their reason for selecting a particular librarian), and experience working with a librarian.
Conclusion – Overall, the research results demonstrate that students prefer to conduct research independently but will consult a librarian if they are not able to find what they need, if they find the research question especially challenging, or if they have spent an unreasonable amount of time conducting research. In-class library instruction, along with professor referrals are the most effective methods for encouraging students to seek out library assistance.


Photo-induced copper-mediated radical polymerization of methyl acrylate (MA) is carried out in DMSO at 15 °C in a tubular photo-flow reactor as well as in a glass-chip based microreactor. Polymerization reactions proceed rapidly to approximately 90% monomer conversion within 20 minutes of reactor residence time. Control of reactions is high as evidenced by ideal polymerization kinetics, low dispersities of the obtained polymers (in the range of 1.1) and linear evolution of number average molecular weights during polymerization reactions. Poly(MA) with average molecular weights between a few hundred and ∼5000 g mol−1 was obtained under retention of pristine end group fidelity. Besides homopolymers, block copolymers can also be successfully synthesized and poly(methyl acrylate)-b-poly(butyl acrylate) block copolymers with a similar low dispersity are obtained. Reactions proceed under homogeneous reaction conditions. This feature allows the reaction to be carried out in milli- and also in microflow devices. In both cases, equally good control is achieved with only minimal adaptation of the reaction protocol, underpinning the simplicity and fast adaptability of the protocol to different flow reactors.


Large vertical mixed flow pump is often used as the sea water supply pump in MSF (Multi-stage Flash) seawater desalination plant. From the point of view of cost reduction, the smaller pump size is strongly required for this type of pump. To satisfy this requirement, higher suction performance should be achieved but there are several issues such as excessive noise, vibration and erosion caused by cavitation in high velocity flow field [1]. Therefore, the present work is aimed at establishing the design technique for suppressing the cavitation which occurs in high velocity field in mixed flow pump.As reported in the previous paper [2], we experienced irregular excessive vibration due to cavitation in vertical mixed flow pump. Although this issue had been solved by applying forward swept impeller [3], the relation between the vibration and tip vortex cavitation was still unclear.This paper describes the investigation results about the relation between unsteady hydraulic exciting force and tip leakage vortex cavitation by CFD (Computational Fluid Dynamics). In the CFD analysis, the tip clearance was considered and full cavitation model was used to evaluate the effect of tip vortex cavitation on hydraulic exciting force [4].From the CFD analysis, the vortex core induced from leading edge of impeller blade was detected and the static pressure and vorticity distributions on vortex center were obtained. From these results, there was no significant difference of these values between no-swept and forward swept impellers. Therefore, it implies that sweep technology does not affect to the strength of vortex. On the other hand, the unsteady behavior of pressure and cavitation area on the impeller blade was observed. Accordingly it is supposed that this fluctuation induced excessive noise, vibration and erosion.Copyright © 2015 by JSME


Scientists are increasingly called upon to engage in policy formulation, but the literature on engagement is strong on speculation and weak on evidence. Using a survey administered at several broadly "ecological" conferences, we investigated: (1) the extent to which respondents engage in policy-related activities (including reporting scientific results, interpreting science for policy makers, integrating science into decision making, taking a position on a policy issue, and acting as a decision maker); (2) what factors best explain these types of engagement; and (3) whether respondents' activity levels match their stated beliefs on such activities. Different factors explain different forms of participation. Past negative experience was identified as a barrier to taking part in policy, while self-perceived competence in navigating the science–policy interface was consistently important in explaining activity across all engagement types, highlighting the importance of training programs linking scientists to policy. Many respondents believed that scientists should interpret, integrate, and advocate, which contrasts with previous research and relatively low levels of self-reported participation in policy.


The purpose of this thesis is to examine how instruction librarians" perceptions of web scale discovery services and their perceptions of the impact of web scale discovery on students" information literacy are reflected in their instruction practices in academic libraries. This study addresses how instruction librarians generally perceive WSDS and students" information literacy as well as how instruction librarians conduct their instruction sessions. The study"s empirical data consists of the responses received through seven semi-structured interviews with ten instruction librarians at three separate universities in the Vastra Gotaland region. The study concludes that library instruction practices reflect many of the librarians" perceptions surrounding WSDS, most notably in the areas of source criticism and critical assessment of search results. The study also shows that the search strategies, techniques, and tools taught in instruction sessions are greatly influenced by librarians" perceptions of the usefulness of WSDS in student search processes. The librarians" responses demonstrate the importance of teaching students search strategies and techniques as well as helping them develop critical evaluation skills that will remain relevant as search technologies continue to evolve.


"I must work the works of Him who sent me while it's day, for when the night is come the time for work will be done away. Would you be willing to work for Jesus any time and every day? He'll reward you when He comes to take His bride away." --Danniebelle Hall, "Work the Works" The popularity of black gospel music has expanded beyond the grassroots network of churches and small concert venues that powered the genre to new heights in the 1950s and early 1960s. Today, gospel has earned a distinct place on mainstream black radio, and gospel videos have moved from being shown on Sunday mornings between 11 A.M. and noon and are now played in rotation with Missy Elliott, Tupac Shakur, and Mariah Carey on BET and VH1. Recent marketing strategies that include concert tours, music videos, e-mail listservs, downloadable ring tones, concert DVDs, and movies have placed the genre's profits well above other forms of popular music. At the center of this popularity is a creative community of singers, composers, producers, instrumentalists, and independent and major records companies that have drawn from myriad musical styles and production methods. More important is gospel's meteoric evolution to a form that today is emblematic of the social, economic, and musical beliefs of the urban identities and theological perspectives that developed in the generations that followed the civil rights movement. The term contemporary gospel, much like its counterpart traditional gospel, has served as an umbrella term that represents the stylistic characteristics and production methods that have defined gospel music from circa 1968 forward. Turn on gospel radio today or download the newest gospel single, and you will hear a complex arrangement of sampled bass lines, explosive rhythms, and intricate vocal interactions that are more reflective of the sound identities that each performer, production team, and record company has created than one singular sound. With the growing influence that R&B, jazz, Western art music, and hip-hop have had on contemporary gospel, producers such as Donald Lawrence, Kevin Bond, Kurt Carr, and J. Moss have become as notable if not as popular as the performers. While the criticism against "secular-sounding" gospel music has grown, and fears that the church has "lost" gospel to the world are nurtured in many traditional circles, the influence of the music--and its accompanying images of dancing choirs, glamorized and highly coiffed purveyors in the newest and hippest fashions--on younger and secular audiences has not lessened. Central to understanding the history and development of contemporary gospel is the role gender that has played in its basic practice and conceptualization. While black men have continued to hold important roles as composers, producers, instrumentalists, and CEOs in gospel music, women have shaped the performance aesthetic of the genre. It was, after all, the creative textural interpretation and vocal dexterity of female vocalists that gave Edwin Hawkins, Walter Hawkins, and Andrae Crouch their signature sounds. Today, artists such as Yolanda Adams, CeCe Winans, Shirley Caesar, and the Clark Sisters have defined and in some cases redefined the sound and image of contemporary gospel and placed it in the realm of mainstream popularity that continues in the vein of singers Mahalia Jackson, Sister Rosetta Tharpe, and Clara Ward, who spread gospel beyond the boundaries of black churches and popularized it on concert stages and in nightclubs during the 1940s and 1950s. Framing the present discussion around the post-civil rights generations (1969-present), specific performers, and the performance approaches each has introduced or popularized, I consider the contributions of African-American women to the development of contemporary gospel music. (1) In an effort to bring clearer understanding to the ever-evolving concept of "contemporary," this discussion extends beyond the work of previous scholars, which has focused on the contemporary gospel sound of the late 1960s and early 1970s. …


Aim/Purpose This paper presents some of the issues that academia faces in both the detection of plagiarism and the aftermath. The focus is on the latter, how academics and educational institutions around the world can address the challenges that follow the identification of an incident. The scope is to identify the need for and describe specific strategies to efficiently manage plagiarism incidents. Background Plagiarism is possibly one of the major academic misconduct offences. Yet, only a portion of Higher Education Institutes (HEIs) appear to have well developed policies and procedures aimed at dealing with this issue or to follow these when required. Students who plagiarize and are not caught pose challenges for academia. Students who are caught pose equal challenges. Methodology Following a literature review that identifies and describes the extent and the seriousness of the problem, procedures and strategies to address the issue are recommended, based on the literature and best practices. Contribution The paper alerts academics regarding the need for the establishment of rigorous and standardized procedures to address the challenges that follow the identification of a plagiarism incident. It then describes how to streamline the process to improve consistency and reduce the errors and the effort required by academic staff. Recommendations for Practitioners To ensure that what is expected to happen takes place, HEIs should structure the process of managing suspected plagiarism cases. Operationalization, workflow automation, diagrams that map the processes involved, clear information and examples to support and help academics make informed and consistent decisions, templates to communicate with the offenders, and databases to record incidents for future reference are strongly recommended. Plagiarism Management 160 Future research This paper provides a good basis for further research that will examine the plagiarism policy, the procedures, and the outcome of employing the procedures within the faculties of a single HEI, or an empirical comparison of these across a group of HEIs. Impact on Society Considering its potential consequences, educational institutions should strive to prevent, detect, and deter plagiarism – and any type of student misconduct. Inaction can be harmful, as it is likely that some students will not gain the appropriate knowledge that their chosen profession requires, which could put in danger both their wellbeing and the people they will later serve in their careers.


This far-ranging book shows how human memory influences the organization of music. The book is divided into two parts. The first part presents basic ideas about memory and perception from cognitive psychology and, to some extent, cognitive linguistics. Topics include auditory processing, perception, and recognition. The second part describes in detail how the concepts from the first part are exemplified in music. The presentation is based on three levels of musical experience: event fusion (the formation of single musical events from acoustical vibrations in the air, on a time scale too small to exhibit rhythm), melody and rhythm, and form. The focus in the latter is on the psychological conditions necessary for making large-scale -- that is, formal -- boundaries clear in music rather than on traditional musical forms. The book also discusses the idea that much of the language used to describe musical structures and processes is metaphorical. It encourages readers to consider the possibility that the process of musical composition can be "a metaphorical transformation of their own experience into sound." The book also touches on unresolved debates about psychological musical universals, information theory, and the operation of neurons. It requires no formal musical training and contains a glossary and an appendix of listening examples.


'My Decade in the Premier League' is Wayne's first hand account of his 10 years playing at the highest level in English football - and for the biggest club in the world. This is his inside story of life on the pitch for Manchester Utd; the League titles, FA Cups, League Cups and Champions League adventures. A must for any Utd fan. Wayne Rooney is widely regarded as one of the leading football players of his generation. A talisman for Manchester United, since his transfer to them in 2004, Rooney is their star player and the first name on the team sheet. In the 10 years since he made his debut as a 16 year old for Everton, he has acquired trophy after trophy, accolade after accolade and headline after headline. 'My Decade in the Premier League' is the inside account of life as a Premier League footballer from the man every one wants to hear from. This is his story, in his words. From gracing the ground at Goodison as an excitable 16 year old to lifting the Champions League trophy with Manchester United. From the emotional high of scoring the winner against Manchester City with that overhead bicycle kick to the crushing low of the thrashing City handed out at Old Trafford in the 2011-12 season. This is a book for the fan who would kill to get just 30 seconds on the pitch at The Theatre of Dreams - to run on the famous turf and score in front of the Stretford End. 'My Decade in the Premier League' gives a real insight in to what goes in to being part of the biggest club in the world; the training pitch, the dressing room, the manager, the coaches and, most importantly, the buzz of crossing that white line and hearing the 76,000 strong crowd chant your name. In intricate, emotional detail Wayne talks about every season he has spent in the Premier League and how it feels to be one the most celebrated footballers on the planet.


Although higher education generally recognizes the value of interdisciplinary collaboration, few colleges and universities successfully encourage, facilitate, or evaluate collaborative work. Disciplinary structures, individualistic mindsets, and a lack of tangible support have been identified as common barriers to integrative knowledge creation among faculty, while situation-specific "minimum critical specifications" (Morgan, 2006) necessary for emergent collaborative work are more challenging to both articulate and establish.
This qualitative case study examines the perspectives and processes of an arts-based, interdisciplinary group of faculty at a medium-sized public university in the Southeastern United States. The participant group, the Appalachian Expressive Arts Collective, developed intuitively and has continued to self-organize without formal institutional oversight. Framed by literature from the emerging field of expressive arts therapy, as well as from organizational development, complexity science, and professional satisfaction theory, this study combines ethnographic research methods with an arts-based, qualitative methodology known as a/r/tography–a "living inquiry" (Springgay, Irwin, & Kind, 2005) that supports the researcher's aesthetic orientation toward data collection, representation, and analysis–in order to facilitate the emergence of relevant and meaningful themes. The inquiry into interdisciplinary collaboration is guided by six research questions that explore: how academic partnerships emerge organically; the relevance of the arts and complexity science to collaborative work; connections with curriculum development and professional satisfaction; and alignments between expressive arts and a/r/tography.
The findings of this study suggest that the primary component of the Collective's collaborations is deep relationship, facilitated by expressive arts perspectives and shared values, especially around creativity and healing. The Collective's organizational development, structure, and working processes are aligned with the Community of Practice model (Wenger, 1998) and can be viewed metaphorically as a complex "living system." Through a lens of complexity science, the Collective demonstrates that strong emergence is aided by a diversity of perspectives and a degree of relational tension. Educational leaders can support collaborative work by increasing opportunities and incentives for intuitive community-building among faculty, by providing holistic faculty development programs, and also by incorporating process-focused measures of collaboration into institutional assessment protocols. Implications for arts-based researchers and practitioners, aspiring collaborators, and institutional administrators are offered, as well as suggestions for further research.


There is water scarcity problem in arid and semiarid areas like the Sana'a basin, eventhough the cities produce a large amount of wastewater. Therefore, reuse of treated wastewater in irrigation is warranted. However, the sewerage system covers only 20 percent of the city of Sana'a. The flow to the Sana'a Wastewater Treatment Plant (WWTP) is estimated to be 50,000 m3/day by the year 2005. This is the available amount for irrigation use.

The main objective of this study was to determine the possible reuse of treated wastewater for irrigation and the extent of the agricultural area that could be irrigated with the treated wastewater. A Geographical Information System facility was then used to select suitable crops and determine the irrigation water requirement.
In spite of the low treatment efficiency of the Sana'a WWTP, especially the microbiological test result, reuse of this water in irrigation has less environmental problems compared to other means of wastewater disposal. Moreover, wastewater is a renewable source of water and provides nutrients for crops and organic matter for soil conditioning.

The soil map was prepared by a consultant within the Sana'a Basin Water Management Project. The soil map was used as the base map layer of this work and the crops to be grown were grouped into three types of crops: deep rooted; shallow rooted; and tree. The soil characteristics such as salinity, texture and the crop suitability were keyed into text tables and joined to the attribute table of the soil map to produce the crop blocks map. From soil units data and command percolation factors of the soils, the map of texture percolation factor was created. The soil texture map was overlaid with the crop blocks map to calculate the percolation losses of every block. The crop water requirement for every block was calculated per month while considering the crop coefficient, kc, for different growth stages throughout the year. The peak water requirement was in May. The total irrigation water requirement was calculated by aggregating the percolation water losses, the peak crop water requirement and the leaching requirement. The total water requirement was found to be 13,058,855 m3/month, which was equal to 5,595 m3/month/ha. The minimum possible irrigated area using wastewater of this project was 268 ha, depending on the irrigation schedule and operation system of the lagoon storage/balance.

An irrigation system was designed for a 30 ha area. The nearest area to the water source was chosen, and a sprinkler irrigation system was suggested to avoid losses due to the scarcity of water in the study area. AutoCAD was used to draw the layout of the irrigated blocks and distribute the sprinklers. This layout was exported to ArcView GIS to show the irrigated area by making a buffering of the sprinklers wetted diameter. An irrigation schedule was suggested as an economic system design with appropriate quantity of water use.

This study recommends connecting the rest (80 percent) of the city of Sana'a to the trunk sewerage system to convey the wastewater to the WWTP for treatment and reuse for irrigation purposes. And the treatment process in the WWTP should give more emphasis to the chlorination and disinfection process and control of the trace element inlet to the WWTP or its removal as a primary treatment of the WWTP. Other wastewater treatment plants should be established at appropriate locations around the city for a satisfactory effluent quality.


The paper deals with diffusion processes of the core dopant during thermal connection (splicing in electric arc) of telecommunication fibers whose parameters vary considerably. A method for defining values of diffusion coefficients GeO2 in SiO2 in splicing temperature has been presented. Better consistence of the dopant Gaussian and diffusion distribution has been found the longer the diffusion time-that is, splicing time. Theoretical analysis of thermally diffused expanded core (TEC) transit area transmission properties was performed which revealed that it is possible to obtain splice loss of thermal connections (splice) of fibers with different parameters, such as of the type G.652 and G.655, below 0.08 dB, using classical connection in electric arc. Whereas, using connection methods that increase the length of TEC, for example, connection by means of gas micro-burners, zero attenuation of such a connection can be accomplished.


The selective hydrogenation of bio-derived furfural was investigated under mild conditions using a series of supported palladium catalysts prepared by a sol-immobilisation technique. Catalysts using alumina and titania supports were more selective towards tetrahydrofurfuryl alcohol. The catalytic activity of 1.19% Pd/TiO2 was evaluated under different reaction conditions and higher selectivity towards tetrahydrofurfuryl alcohol was observed when using 2-propanol as a solvent, and the yield of tetrahydrofurfuryl alcohol decreased as reaction temperature increased. The performance of the Pd catalyst was enhanced by the addition of Pt and a 95% yield of tetrahydrofurfuryl alcohol was achieved. The catalysts were characterised using a range of techniques, and the synergistic effect of adding Pt to Pd was due to an electronic promotional effect.


Title of Dissertation: ROLE OF FEED PROTOCOL IN ACHIEVING CHAOTIC MIXING OF HIGHLY FILLED FLOW SYSTEMS DURING FILLING THE EMPTY CAVITY Yue Huang, Doctor of Philosophy, 2006 Dissertation directed by: Professor David Bigio Department of Mechanical Engineering Chaotic mixing of highly filled viscous fluids is desired but hardly achieved in the electronic packaging industries. The demand for high reliability found in electronic package attracts more and more researchers to study the properties and distribution of binders and filler particles. These will affect properties such as coefficient of thermal expansion and stiffness. Both of these contribute strongly to reliability. The filler concentration, size distribution and spatial distribution must be examined in a structured manner to understand their effects on final properties. However, most studies deal with filler concentration and size distribution, while very few studies have tied the particle spatial distribution to the properties. It is not enough to just properly control the filler concentration and size distribution. The more uniform filler distribution, the more uniform are local properties, and this can be achieved by well-designed mixing processes. Mixing is very important and in many cases the goodness of the mixing of fillers will affect or determine the properties of the products. In this thesis, the local properties of electronic package and their relations with filler particle distribution are quantified. For the first time, a new feed protocol that can generate chaotic mixing during filling cavity by implementing periodic and aperiodic filling process is presented. Instead of using single gate in the molding process, we have developed a two-gate feeding protocol. A numerical simulation experiment is conducted on a 2-D square cavity to examine the mixing of polymer fluid in low Reynolds number flows. Since there are a vast number of geometries in electronic packages, only cavities with 46 and 49 bumps, which can be treated as solder balls or leadframe, is investigated. Periodic and aperiodic feed protocols resulted in exponential growth of the distance between two adjacent particles, an indication of chaotic mixing. Entropic study shows that the global mixing has been improved 858% compared to single gate feeding. The improved properties and reliability could be foreseen in electronic package. ROLE OF FEED PROTOCOL IN ACHIEVING CHAOTIC MIXING OF HIGHLY FILLED FLOW SYSTEMS DURING FILLING THE EMPTY CAVITY


This study investigates lacustrine and fluvial sediments on the Sala Us River in the Mu Us Desert in central north China. Significant changes in environmental dose rate in part of the section could be shown to have occurred from measurements of the present day radioactivity and by the age reversal for some samples that had been dated by optically stimulated luminescence (OSL) measurements on quartz. These changes in dose rate can be attributed to recent uptake of radioactive elements found in the sediments; this resulted in significant underestimation of the OSL ages. In this study, the new isochron method using K-feldspar grains has been applied to overcome the effects of changes in dose rate. Calculations are used to show that changes in the environmental dose rate factors, i.e. K, U, Th, water content and cosmic ray flux, and disequilibrium in the U and Th decay chains, e.g. radon escape, have a negligible effect on the isochron age. After applying the new isochron method, the effects of changes in dose rate caused by recent uptake of radioactive elements and changes in past water content were effectively overcome and true ages are obtained; this was verified by repeating the luminescence isochron measurements on samples of overlying and underlying sediments.


Business Process Management (BPM) is an influential concept in information systems (IS) research and management practice. While a great number of studies dealt with developing methods, procedures, or tools for BPM, especially process modeling, today the question of how to assess and – from that point on – to develop BPM capabilities in a real-life organization has become key to BPM practice and is becoming a central element in BPM research as well. A plethora of BPM maturity models have been designed for the purpose of guiding the development of BPM capabilities in organizations. In this study, we take a critical perspective on maturity models for BPM capability development and present a case study example where maturity model-based guidance is rendered to be inadequate if not further considering organizational position and environment. Our theory discussion introduces alternative takes on BPM capability development, lays out implications for BPM practice, and presents potentially fruitful paths for future research and theory in the area of BPM capability development.


The paper highlights key issues emerging from a "conversion programme", the Accompanying Measures
Eastern Region (AMER) Project, during which over 150 hand-pumps previously centrally-managed and
maintained by government (the 3000 Wells Project), were transferred to rural communities for ownership
and management (COM). Implementation was carried out in the Eastern Region of Ghana between 1996
and 2001. To ease the burden on communities to make the transition "transfer-friendly", communities could
pay 50% of arrears owed over six months for the rest to be written off, local residents were trained for
maintenance of facilities and there was free rehabilitation of the hand-pumps. Even though some challenges
were encountered, there were interesting findings such as the long time it takes for COM to take root in rural
communities towards sustainability, the need to make alternative arrangements for maintenance of facilities
and the complex relationships between socio-cultural configurations and payment of arrears.


IMPORTANCE
Asthma is the most prevalent chronic illness among children, remaining a leading cause of pediatric hospitalizations and representing a major financial burden to many health care systems.

OBJECTIVE
To implement a new auditing process examining whether differences in hospital practice style may be associated with potential resource savings or inefficiencies in treating pediatric asthma admissions.

DESIGN, SETTING, AND PARTICIPANTS
A retrospective matched-cohort design study, matched for asthma severity, compared practice patterns for patients admitted to Children's Hospital Association hospitals contributing data to the Pediatric Hospital Information System (PHIS) database. With 3 years of PHIS data on 48 887 children, an asthma template was constructed consisting of representative children hospitalized for asthma between April 1, 2011, and March 31, 2014. The template was matched with either a 1:1, 2:1, or 3:1 ratio at each of 37 tertiary care children's hospitals, depending on available sample size.

EXPOSURE
Treatment at each PHIS hospital.

MAIN OUTCOMESS AND MEASURES
Cost, length of stay, and intensive care unit (ICU) utilization.

RESULTS
After matching patients (n = 9100; mean [SD] age, 7.1 [3.6] years; 3418 [37.6%] females) to the template (n = 100, mean [SD] age, 7.2 [3.7] years; 37 [37.0%] females), there was no significant difference in observable patient characteristics at the 37 hospitals meeting the matching criteria. Despite similar characteristics of the patients, we observed large and significant variation in use of the ICUs as well as in length of stay and cost. For the same template-matched populations, comparing utilization between the 12.5th percentile (lower eighth) and 87.5th percentile (upper eighth) of hospitals, median cost varied by 87% ($3157 vs $5912 per patient; P < .001); total hospital length of stay varied by 47% (1.5 vs 2.2 days; P < .001); and ICU utilization was 254% higher (6.5% vs 23.0%; P < .001). Furthermore, the patterns of resource utilization by patient risk differed significantly across hospitals. For example, as patient risk increased one hospital displayed significantly increasing costs compared with their matched controls (comparative cost difference: lowest risk, -34.21%; highest risk, 53.27%; P < .001). In contrast, another hospital displayed significantly decreasing costs relative to their matched controls as patient risk increased (comparative cost difference: lowest risk, -10.12%; highest risk, -16.85%; P = .01).

CONCLUSIONS AND RELEVANCE
For children with asthma who had similar characteristics, we observed different hospital resource utilization; some values differed greatly, with important differences by initial patient risk. Through the template matching audit, hospitals and stakeholders can better understand where this excess variation occurs and can help to pinpoint practice styles that should be emulated or avoided.


This congressional testimony summarizes the effects on consumers and the economy of Dodd-Frank, the Durbin Amendment the Consumer Financial Protection Bureau, and other government regulations (such as the CARD Act of 2009) enacted in the wake of the recent financial crisis. The testimony notes that the combined effect of these laws and regulations has resulted in higher bank fees, a dramatic reduction in access to free checking, an increase in the number of unbanked consumers, a dramatic reduction in access to credit cards for low-income consumers, and continued low access to mortgages, especially among lower-income and higher-risk borrowers. In addition, because of the crushing and disproportionate burden of Dodd-Frank's regulations on smaller banks, the law has promoted consolidation of the banking industry and forced many smaller banks to exit certain product markets, especially mortgages. This combined effect has reduced choice and competition for consumers. Finally, the lack of democratic accountability over the CFPB has resulted in an agency defined by bureaucratic overreach, resulting in an invasive and reckless data-mining project and assertion over many industries and products that stand outside of the agency's authorized jurisdiction.


Perylene bisimides (PBIs) can be functionalised to enable controlled aggregation into complex supramolecular structures and are promising materials for photovoltaic and solar fuel applications. Amino acid appended PBIs such as PBI-alanine (PBI-A) have been found to form photoconductive films containing worm-like structures that enable charge transport. However, despite being strong chromophores in the visible region, when PBI-A films are prepared by drying down solutions, activity only occurs under UV illumination. This limits potential applications. The requirement for UV illumination has previously been suggested to be due to the large ion-pair energy in the low dielectric environment of the dried samples. Hydrogel films, rehydrated xerogels and dry xerogels of PBI-A can also be prepared offering an ideal sample set to examine the influence of hydration on charge-separation. Using transient absorption (TA) spectroscopy, we demonstrate a correlation between water content and efficiency of generation of long-lived charge separated states within the PBI-A materials, highlighting their potential, particularly for light-driven water splitting.


AIM
Topiramate is an antiepileptic drug with multiple mechanisms of action that is also used for migraine prophylaxis. This study aimed to investigate the efficacy of topiramate therapy for migraine prophylaxis, based on vasomotor reactivity ([VMR] an indicator of cerebral autoregulation), and to identify changes in cerebral hemodynamics during the treatment.

MATERIAL AND METHODS
We included 20 migraine (with aura) patients (group 1) and 20 healthy controls (group 2) in the study. Transcranial Doppler monitoring was performed in both groups with patients in the supine and resting position. Using a two-sided temporal window at depths of 45-60 mm for the middle cerebral artery (MCA) and depths of 60-70 mm for the posterior cerebral artery (PCA), basal flow rates and VMR values were measured. Group 1 initially received 25 mg/d of topiramate orally, and then the dose was increased 25 mg every week. At the fourth week; the optimal dose was increased to 50 mg b.i.d. and the treatment was continued at this dose. Transcranial Doppler parameters were re-evaluated 2 months after treatment. In addition, the number of attacks per month, duration of pain, and visual analog scale (VAS) scores obtained before the treatment and 2 months after the treatment in group 1 were compared.

RESULTS
Basal flow rates and VMR values recorded from the right and left MCA in group 1 were significantly higher than those in the control group (P < 0.05). Flow velocities obtained from the right and left MCA, and the VMR values in group 1 after topiramate treatment did not differ significantly from those in the control group (P > 0.05). In addition, the number of attacks, duration of pain, and VAS scores in group 1 were significantly lower after the treatment than before the treatment (P < 0.05).

CONCLUSION
Topiramate is an effective prophylactic treatment in migraine with aura patients and appeared to play a positive role in the regulation of cerebrovascular autonomic control.


The study of chemistry is central within science and other associated degrees. At the University of New England in Armidale academics need to provide chemistry teaching in both a distance and the traditional on-campus mode within science and other degrees. This study explores the contribution that the adoption of Adobe Connect technology can make to support of students and enhancement of their learning. The preliminary response from students has been unequivocally positive with an increased confidence around unit materials gauged by improved student learning outcomes and unsolicited positive comments.


Capitalizing on large pre-trained models for various downstream tasks of interest have recently emerged with promising performance. Due to the ever-growing model size, the standard full fine-tuning based task adaptation strategy becomes prohibitively costly in terms of model training and storage. This has led to a new research direction in parameter-efficient transfer learning. However, existing attempts typically focus on downstream tasks from the same modality ( e.g. , image understanding) of the pre-trained model. This creates a limit because in some specific modalities, ( e.g. , video understanding) such a strong pre-trained model with sufficient knowledge is less or not available. In this work, we investigate such a novel cross-modality transfer learning setting, namely parameter-efficient image-to-video transfer learning . To solve this problem, we propose a new SpatioTemporal Adapter (ST-Adapter) for parameter-efficient fine-tuning per video task. With a built-in spatio-temporal reasoning capability in a compact design, ST-Adapter enables a pre-trained image model without temporal knowledge to reason about dynamic video content at a small ( ∼ 8%) per-task parameter cost, requiring approximately 20 times fewer updated parameters compared to previous work. Extensive experiments on video action recognition tasks show that our ST-Adapter can match or even outperform the strong full fine-tuning strategy and state-of-the-art video models, whilst enjoying the advantage of parameter efficiency.


The CGIAR Research Program on Fish Agri-Food Systems (FISH) focuses on the interlinked challenges of sustainable aquaculture and small-scale fisheries (SSFs), and enhancing the contribution of fish to poverty reduction, improved human nutrition and environmental management, with a geographical focus on Africa, Asia and the Pacific. Sustainable aquaculture research within FISH includes a cluster of research on "fish health, nutrition and feeds." This report is the outcome of a workshop held at WorldFish HQ on 28-29 November 2017 intended to elaborate a research and partnership agenda for key health research activities within the FISH, with an emphasis on tilapia from 2017 to 2022. The workshop identified key partnerships and responsibilities for implementing the research, and impact pathways for delivering outcomes at scale in key focal and scaling countries.


In this review, we provide insight into the surface forces of conducting polymers, a class of "intelligent" materials that offer unique strategies for controlling biomolecular interactions in wide-ranging biomedical applications. Critical to the success of these applications is that the polymer interface is exposed to biological fluids whose interactions are controlled through the polymer surface chemistry and electrochemical switching of the surface properties. There is, however, little known about the intermolecular and surface forces that govern these interactions. Therefore, the purpose of this review is to more closely examine the forces that mediate interactions with biological entities, including forces such as van der Waals, electrostatic, hydrophobic, and hydrogen bonding. We introduce relevant surface properties such as surface energy and surface potential, and demonstrate how they manifest as forces. In particular, we highlight the emerging use of Atomic Force Microscopy for directly measuring these forces at the single molecule level; a unique capability that is enabling deconvolution of complex biomolecular interactions with conducting polymers. Finally, we provide an overview of biomolecular interactions, namely model proteins and DNA, and conclude by discussing a growing area of interest; the spatio-temporal and reversible control of biomolecular forces via electrical stimulation.


Private and confidential information is increasingly stored online and increasingly being exposed due to human errors as well as malicious attacks. Information leaks threaten confidentiality, lead to lawsuits, damage enterprise reputations, and cost billion of dollars. While distributed computing architectures provide data and service integration, they also create information flow control problems due to the interaction complexity among service providers. A main problem is the lack of an appropriate programming model to capture expected information flow behaviors in these large distributed software infrastructures. This research tackles this problem by proposing a programming methodology and enforcement platform for application developers to protect and share their sensitive data. We introduce Aeolus, a new platform intended to make it easier to build distributed applications that avoid the unauthorized release of information. The Aeolus security model is based on information flow control but differs from previous work in ways that we believe make it easier to use and understand. In addition, Aeolus provides a number of new mechanisms (anonymous closures, compound tags, boxes, and shared volatile state) to ease the job of writing applications. This thesis provides examples to show how Aeolus features support secure distributed applications. It describes the system design issues and solutions in designing a prototype implementation and presents performance results that show our platform has low overhead. Thesis Supervisor: Barbara H.

The objective of this research was to investigate the stripping problem in bituminous mixtures using both conventional and image processing techniques (IPT). Partial factorial combinations of asphalt mixture slabs were fabricated. A Marshall mold was modified to produce slabs of 300 mm × 300 mm × 60 mm. The mixtures were prepared using different combinations: two types of aggregates (limestone and valley gravel), two asphalt penetration grades (80/100 and 60/70), three types of additives (lime, cement, and a mixture of lime and cement), and one aggregate gradation (average of ASTM boundaries). The slabs were exposed to one of four environmental conditioning techniques: wet-dry (W-D), freezing-thawing (F-T), water immersion (I), and surface bonding (S-B). Eighty-one slabs were prepared, 19 were tested without conditioning (control slabs), and the rest were exposed to different weathering conditioning. Four cores were prepared from each slab, two for the indirect tensile strength test and the others for the Marshall stability test. A normal-based camera was used to map the surfaces of the control and conditioned slabs as well as cross-sections generated from cores tested under the indirect tensile strength test. The Silicon Video Image Processing (SVIP) software was used to digitize images for the surfaces of slabs and cores. Images were analyzed to prepare statistical parameters, intensity diagrams, and histograms for intensities based on two approaches: area-based analysis and line-based analysis. Results of the analysis indicated that 1) conventional and image processing techniques proved that surface bonding increased stability and tensile strength for conditioned slabs more than for unconditioned slabs; 2) IPT predicted stripping in limestone mixtures with AC 80/100 using the retained intensity concept and this result agreed with that of retained Marshall stability (RMS); however, it did not consistently predict the stripping potential of mixtures consisting of valley gravel due to the tone intensity effect of aggregate; 3) lime additive demonstrated the best indirect tensile strength and Marshall stability; however, the additive mix consisting of lime and cement exhibited reduction in water damage for mixtures with AC 60/70; 4) slab mixtures resisted weather conditioning more than conventional cylindrical Marshall specimens; and 5) an area-based analysis scheme using peaks, not averages of intensities, was more reliable in predicting stripping than the line-based analysis, and it was more reliable for core cross-sections than slab surfaces.


Potential insomnia in healthcare workers is a public health concern as it may degrade the quality of patient care. We examined the prevalence of insomnia symptoms in healthcare workers and their perceived need for a sleep intervention. Participants were 62 nurses working full-time at a U.S. hospital. These nurses were asked about background characteristics, perceived stress, sleep concerns, and need for a sleep intervention. They also participated in 14-day ecological momentary assessment (EMA) and actigraphy sleep study. A qualitative analysis showed that the majority (92%) of participants reported at least one sleep concern with insomnia-related concerns being most prevalent (68%). Quantitative analyses indicated that those with insomnia-related concerns had higher perceived stress overall and lower EMA sleep sufficiency and sleep quality. Moreover, participants with insomnia concerns had shorter actigraphy-measured nap duration prior to non-workdays than those without. Nearly all (95%) expressed interest in participating in a sleep intervention; an online format and mindfulness contents were most preferred. Our results suggest a high prevalence of insomnia symptoms and a high interest in a sleep intervention in nurses. Information obtained from this study could be used to deliver a tailored sleep intervention for nurses whose role in public health is essential.

To investigate the use and development of the idea of adventure in brasilian sports field was the main goal of this study. Due to the enormous variability of the contemporary experience of adventure, I tried to follow the developments of a local version from where doubts about its specificity emerged. I started, then, on how this notion was thought and rationalized and, at the same time, on its practice in the city of Brotas (São Paulo state), self entitled the Brazilian capital of adventure . The study of adventure in this ambiance, undeniably embodied, led me to put my own body to work for its understanding and to focus on rafting practice in Brotas, as the condition of possibility of this experiment. However, during the experimentation I realized adventure held the sporting component only as one of the possible elements of its exploring. While making the effort to put in words so many angles, objects in dispute, categories of accusation and self praising discourses that circumscribe the hues on the concept of adventure I ended on acknowledging that the main concerns of adventure in Brotas regard not only the amateur sport, but also the professionalization of tourism and, before it all, an environmental project. Through the problematization of these themes, "adventure as work" came up as an unpredicted matter but a core question to the ethnographic research. And I noted that it is compromised with a peculiar notion of nature and that it is produced in opposition to the concept of radicality. But that, even though the exaltation of nature produces the detachment of radicality, the last one is regained as the contemporary notion of adventure is created so that, and it then demands, a certain type of tourist and a specific kind of worker, the adventure conductor , whose practices are related not to the avoidance, but to the facing of certain risks, mingled with the notions of safety and technique.


Esophageal atresia (EA) presents some of the greatest technical hurdles that pediatric has to face. Postnatally, the classical clinical presentation of an infant with EA is an abnormally mucousy infant who is drooling excessive amount of saliva. Diagnosis confirmed when an orogastric tube cannot be passed through the mouth into the stomach. Examination should assess the as cardiac, anal limb. The purpose of the surgery is to divide the trachea esophageal fistula (TEF) and to restore esophageal continuity blind-ending upper esophageal. Achalasia is an uncommon disorder of esophagus dysmotility. Patients typically present with a history of progressively worsening dysphagia that begins with solid foods. The initial diagnosis test in child with dysphasia is usually a contrast esophagogram. Classic findings include a dilated, dysmotile esophagus and a bird's beak deformity at the gastroesophageal junction. The main treatments of achalasia are esophageal myotomy, balloon dilation or botulism toxin. Esophageal diverticula are often first suspected on Chest X ray(CXR) due to presenting symptoms. These lesions can cause wheezing, dyspnea, hemoptysis and recurrent pneumonia due to airway compression and dysphasia due to esophagus compression. These duplications should be further investigated by CT scan or Magnetic resonance imaging (MRI). The preferred method of treatment is thoracoscopy or thoracotomy.


Positive and negative feelings were central to the development of economics, especially in utility theory in classical economics. While neoclassical utility theory ignored feelings, behavioral economics more recently reintroduced feelings in utility theory. Beyond feelings, economic theorists use full-fledged specific emotions to explain behavior that otherwise could not be understood or they study emotions out of interest for the emotion itself. While some analyses display a strong overlap between psychological thinking and economic modelling, in most cases there is still a large gap between economic and psychological approaches to emotion research. Ways how to reduce this gap are discussed.


More and more software systems are now made of multiple collaborating third-party components. Enabling fine-grained control over the communication between components becomes a major requirement. While software isolation has been studied for a long time in operating systems (OS), most programming languages lack support for isolation. In this context we explore the notion of proxy. A proxy is a surrogate for another object that controls access to this object. We are particularly interested in generic proxy implementations based on language-level reflection. We present an analysis that shows how these reflective proxies can propagate a security policy thanks to the transitive wrapping mechanism. We present a prototype implementation that support transitive wrapping and allows a fine-grained control over an isolated object graph.


"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover." --Mark Twain It's telling that Mark Twain chose sailing as a metaphor for living life to the fullest. Throughout history, humankind has been going to sea in boats and ships--for the purposes of trade, exploration, transport, fishing, and pure enjoyment. The Little Red Book of Sailing Wisdom contains some of the most moving, perceptive, witty, and inspirational words ever spoken or written about the sea-faring life. Novelists, politicians, explorers, playwrights, poets, musicians, and celebrities weigh in on life upon the water, under sail. These are just some of the folks whose words appear in these pages: *Daniel Defoe *Ted Kennedy *Charles Dickens *Franklin Roosevelt *Herman Melville *Dennis Connor *Patrick O'Brian *Larry Ellison *Eugene O'Neill *Thor Heyerdahl *Jack London *Isak Dinesen *William F. Buckley *And dozens of others! Skyhorse Publishing, as well as our Sports Publishing imprint, is proud to publish a broad range of books for readers interested in sports--books about baseball, pro football, college football, pro and college basketball, hockey, or soccer, we have a book about your sport or your team. In addition to books on popular team sports, we also publish books for a wide variety of athletes and sports enthusiasts, including books on running, cycling, horseback riding, swimming, tennis, martial arts, golf, camping, hiking, aviation, boating, and so much more. While not every title we publish becomes a New York Times bestseller or a national bestseller, we are committed to publishing books on subjects that are sometimes overlooked by other publishers and to authors whose work might not otherwise find a home.


Apatite fission-track (AFT) analysis has been widely used during the past 30+ years to constrain the low-temperature thermal histories of many igneous, metamorphic and sedimentary rocks in a wide range of geological settings. Applicable geological settings include orogenic belts, rifted margins, faults, sedimentary basins, cratons, and mineral deposits. The types of geologic problems that can be addressed include the timing and rates of tectonic events, sedimentary basin evolution, the timing of hydrocarbon generation and ore mineralization, the absolute age of volcanic deposits, the effects of major climatic changes on the near-surface geothermal gradient, and long-term landscape evolution. Early work by Naeser (1967) and Wagner (1968, 1969) first established the basic procedures that enabled the fission-track dating method to be applied routinely to these geologic problems. Fleischer et al. (1975) summarized the early studies of the broader discipline of nuclear-track detection in different solid-state materials. More recent comprehensive overviews of fission-track applications have been provided by Naeser and McCulloh (1989), Wagner and Van den haute (1992), Gallagher et al. (1998), Van den haute and De Corte (1998), Dumitru (2000), and Gleadow et al. (2002).

Etched, natural fission tracks in several apatite grains are shown in Figure 1⇓. Successful AFT analysis is limited by the following: 1) the availability of apatite from which useful AFT data can be obtained, often due to a lack of apatite of sufficient grain size and quality within available rock types, or, alternatively, the lack of available rock samples due to minimal outcrop exposure or other reasons, 2) economic considerations in terms of the time and money required to obtain sufficient AFT data, 3) the inherent limitations of AFT data to resolve geological thermal history information, often related to limited numbers of accumulated spontaneous fission tracks due to …


Abstract : In organizations with access to the internet, the potential for data leakage is ever present. Data loss prevention is a difficult issue because exfiltration channels, such as modern webmail services, are readily available to insiders. An insider can paste text into a webmail message to bypass other controls. Therefore, monitoring must include the content of this communication. A data loss prevention control determines if the content in outgoing web requests is similar to the organization's intellectual property, actively blocks suspicious requests, and logs these events. This technical note describes how a control can monitor web request traffic for text-based data exfiltration attempts and block them in real time. Using this control can help an organization protect text-based intellectual property, including source code repositories.


Nanotechnology has the potential to revolutionize cancer diagnosis and therapy. Advances in protein engineering and material science have contributed to novel nanoscale targeting approaches that may bring new hope to cancer patients. Several therapeutic nanocarriers have been approved for clinical use. However, to date, there are only a few clinically approved nanocarriers that incorporate molecules to selectively bind and target cancer cells. This review examines some of the approved formulations and discusses the challenges in translating basic research to the clinic. We detail the arsenal of nanocarriers and molecules available for selective tumor targeting and emphasize the challenges in cancer treatment.


Asset Pricing Theory is an advanced textbook for doctoral students and researchers that offers a modern introduction to the theoretical and methodological foundations of competitive asset pricing. Costis Skiadas develops in depth the fundamentals of arbitrage pricing, mean-variance analysis, equilibrium pricing, and optimal consumption/portfolio choice in discrete settings, but with emphasis on geometric and martingale methods that facilitate an effortless transition to the more advanced continuous-time theory.
 Among the book's many innovations are its use of recursive utility as the benchmark representation of dynamic preferences, and an associated theory of equilibrium pricing and optimal portfolio choice that goes beyond the existing literature.
 Asset Pricing Theory is complete with extensive exercises at the end of every chapter and comprehensive mathematical appendixes, making this book a self-contained resource for graduate students and academic researchers, as well as mathematically sophisticated practitioners seeking a deeper understanding of concepts and methods on which practical models are built.

 Covers in depth the modern theoretical foundations of competitive asset pricing and consumption/portfolio choice Uses recursive utility as the benchmark preference representation in dynamic settings Sets the foundations for advanced modeling using geometric arguments and martingale methodology Features self-contained mathematical appendixes Includes extensive end-of-chapter exercises


Chief Judge of the Federal Circuit Court John Pascoe, and the Chief Justice of the Family Court Diana Bryant, are both calling for an inquiry into international surrogacy. For Judge Pascoe, this reflects a life-long concern for the protection of children and a deep engagement with human rights in Asia. Julie McCrossin reports on misgivings about the role of Australian lawyers in international surrogacy and why there is a lack of urgency in our legal response.


In the late 1990s an international feminist network, Gender at Work, wrote about the 'deep structure' of organisations through which gender discriminatory norms and power relations are reproduced. In this article, the authors reflect on the evolution since the Fourth World Conference on Women held in Beijing in 1995 of Gender at Work's theory and practice on approaches to shift deep structure. The Gender at Work Analytical Framework, used by dozens of organisations worldwide to assess, strategise and evaluate the process of organisational change, is described. Using a case study on the Dalit Women's Livelihood Accountability Initiative in Uttar Pradesh, India, the article demonstrates the adaptation of the Analytical Framework for working directly with community-level programmes, highlighting its strength at bringing into focus the deeply entrenched social norms and deep structures that exclude women from claiming their rights. The article concludes with reflections on what Gender at Work has learned since Beijing about working to challenge deep structures in organisations, programmes and systems.


This thesis proposes a wall-following algorithm for mobile robots using the Extended Kalman Filter. The robot navigates in a known environment where the baseboard of the wall is used as a natural landmark and indentified by using the Hough transform. The prediction phase of the Kalman Filter is implemented using the odometry model of the robot. The update phase directly uses the parameters of the lines detected by the Hough algorithm to correct the robot's pose. A proportional control is then performed to adjust the speeds on the wheels of the robot so that it follows the wall in a straight line. The results provided by the Matlab simulation environment showed that the wall-following algorithm could converge well to the real world values.


The global network of terrestrial protected areas (PAs) has experienced a fourfold expansion since the 1970s. Yet, there is increasing debate around the role of the global PA estate in covering and sustaining threatened species, with serious ramifications for current PA financing and the setting of post‐2020 global conservation targets. By comparing "past" (1970s) and current distribution range of 237 mammals, and measuring the proportion of range covered by PAs in the past and in the present, we show that a small number of PAs have now become the last bastions of hope for ensuring the persistence of many mammal species. For 187 species (∼79% of those analyzed) the proportion of range covered by PAs has doubled over the time period, with 10% of all species now having most of their current range protected. This increase in proportional protection over time is largely due to a retreat of species distribution (outside existing PAs) and, in smaller part, to PA expansion. It is clear that adequately resourcing those PAs critical in sustaining mammal species is now essential, to avert a worldwide rapid mammal loss.


Extraction of text lines from handwritten/printed document images is one of the important steps in the process of an Optical Character Recognition (OCR) system. In case of handwritten document images, presence of skewed, touching or overlapping text line(s) makes this process a real challenge to the researcher. In the present work, a new text line extraction technique based on line contour estimation is reported. Here, digitized document image is initially partitioned into a number of vertical fragments of equal width. Then all the line segments present in these vertical fragments are detected. Finally, the neighboring line segments are analyzed to place them inside the line boundary in which they actually belong. For experimental purpose, the developed technique is tested on CMATERdb1.2.1 database and present technique extracts 88.44% text lines successfully.


In this study, we examined the provision and development of lifelong learning within institutions of higher education in British Columbia and explored some of the institutional characteristics that enable or discourage it. The results suggest that most lifelong learning opportunities are directed toward enhancing employment and career opportunities rather than citizenship development. Yet, as the demand for higher education and the number of adult learners enrolling in programs continue to increase, these institutions are well-positioned to develop new forms of education that acknowledge, accommodate, and respect the concerns and interests of lifelong learners.


This graceful historical novel traces Shakespeare's momentous path of creative and emotional self-discovery focusing on his apprentice years and concluding before the great plays that would earn him his fame. It begins with the glover's son roaming the fields of Stratford, hungry for knowledge and restless to escape the boundaries of his small town and loveless marriage. Leaving his family for the turbulence and excitement of London, Will becomes a struggling actor whose charmed, reckless circle of literary and theatrical friends includes John Heminges, Ben Jonson, and Christopher Marlowe - men who will in time create an unforgettable period of theater. All the while, however, Shakespeare continues to challenge himself as a writer; soon he is selling his plays and earning acclaim in the world of the London theater and aristocracy. Yet perhaps his finest and most heartfelt writing of the period can be found in the sonnets written for the Earl of Southampton, the beautiful young lord whose affection and aloofness stir the poet's soul. The Earl becomes Shakespeare's patron, friend, romantic rival, and eventually, his lover. With the Earl and the bewitching Italian musician Emilia Bassano, Shakespeare plunges deep into a tempestuous love triangle that will threaten both his desire to write and his sense of himself.


Precambrian rocks are exposed in cores of uplifts, and possibly early Precambrian granites were the source of uranium in Tertiary host rocks. Paleozoic rocks occur along flanks of Laramide uplifts and in low-angle thrusts. The only significant uranium deposits are low-grade, but extensive, in phosphatic rocks. Mesozoic rocks are thicker, and locally Cretaceous sandstones are major hosts for uranium. Deformation began in Cretaceous, and in early Eocene relief reached a maximum and thick beds of coarse conglomerate were deposited. Lakes formed in the basins and uraniferous phosphates occur in the lake deposits. Ash beds are abundant in the Oligocene and later Tertiary. Alternatives for formation of Eocene uranium deposits are considered; it is suggested that they may be an end product of a long complex sequence of events, with redistribution near the end of the Pliocene.
