Typically software engineers implement their software according to the design of the software
structure. Relations between classes and interfaces such as method-call relations and inheritance
relations are essential parts of a software structure. Accordingly, analyzing several types of
relations will benefit the static analysis process of the software structure. The tasks of this
analysis include but not limited to: understanding of (legacy) software, checking guidelines,
improving product lines, finding structure, or re-engineering of existing software. Graphs with
multi-type edges are possible representation for these relations considering them as edges, while
nodes represent classes and interfaces of software. Then, this multiple type edges graph can
be mapped to visualizations. However, the visualizations should deal with the multiplicity of
relations types and scalability, and they should enable the software engineers to recognize visual
patterns at the same time.
To advance the usage of visualizations for analyzing the static structure of software systems,
I tracked difierent development phases of the interactive multi-matrix visualization (IMMV)
showing an extended user study at the end. Visual structures were determined and classified
systematically using IMMV compared to PNLV in the extended user study as four categories:
High degree, Within-package edges, Cross-package edges, No edges. In addition to these structures
that were found in these handy tools, other structures that look interesting for software
engineers such as cycles and hierarchical structures need additional visualizations to display
them and to investigate them. Therefore, an extended approach for graph layout was presented
that improves the quality of the decomposition and the drawing of directed graphs
according to their topology based on rigorous definitions. The extension involves describing
and analyzing the algorithms for decomposition and drawing in detail giving polynomial time
complexity and space complexity. Finally, I handled visualizing graphs with multi-type edges
using small-multiples, where each tile is dedicated to one edge-type utilizing the topological
graph layout to highlight non-trivial cycles, trees, and DAGs for showing and analyzing the
static structure of software. Finally, I applied this approach to four software systems to show
its usefulness.


Between the Gilded Age and the Progressive Era, American state legislatures enacted a series of new laws that delineated a class of citizens who were deemed ineligible to participate in the institution of marriage. Scholars have characterized this development as evidence that lawmakers had lost faith in a laissez-faire approach to nuptial governance, and thus transformed marriage into an object of public regulation. This essay argues that behind the ostensible nuptial privatism of the mid-nineteenth century lay a self-conscious policy of judicial governance. Judges invoked the language of nuptial privacy and the common law of contract strategically to advance their vision of moral and economic discipline. The new marital prohibitions thus represented, the essay argues, not the expansion of the state's police power into the previously private realm of domestic relations, but rather a critical transformation in how nuptial reformers and lawmakers understood the relationship between marriage and the well-being of the polity. Fueled by growing concerns about pauperism, the racial character of the urban proletariat, and the collapse of the economically independent single-male-breadwinner household, the changing form of nuptial governance signaled a thoroughgoing intellectual and strategic reorientation from an understanding of marriage as forming economically and morally viable households—the fundamental units of society—to an understanding of marriage as a largely procreative institution, as the literal source of the citizenry. This reconceptualization of marriage underwrote a strategy of nuptial governance that mobilized marriage as a strategy in the state's regulation of social reproduction.


AI theory and its technology is rarely consulted in attempted resolutions of social problems. Solutions often require that decision-analytic techniques be combined with expert systems. The emerging literature on combined systems is directed at domains where the prediction of human behavior is not required. A foundational shift in AI presuppositions to intelligent agents working in collaboration provides an opportunity to explore efforts to improve the performance of social institutions that depend on accurate prediction of human behavior. Professionals concerned with human outcomes make decisions that are intuitive or analytic or some combination of both. The relative efficacy of each decision type is described. Justifications and methodology are presented for combining analytic and intuitive agents in an expert system that supports professional decision making. Psychological grounds for the allocation of functions to agents are reviewed. Jury selection, the prototype domain, is described as a process typical of others that, at their core, require the prediction of human behavior. The domain is used to demonstrate the formal components, steps in construction, and challenges of developing and testing a hybrid system based on the allocation of function. The principle that the research taught us about the allocation of function is "the rational and predictive primacy of a statistical agent to an intuitive agent in construction of a production system." We learned that the reverse of this principle is appropriate for identifying and classifying human responses to questions and generally dealing with unexpected events in a courtroom and elsewhere. This principle and approach should be paradigmatic of the class of collaborative models that capitalizes on the unique strengths of AI knowledge-based systems. The methodology used in the courtroom is described along with the history of the project and implications for the development of related AI systems. Empirical data are reported that portend the possibility of impressive predictive ability in the combined approach relative to other current approaches. Problems encountered and those remaining are discussed, including the limits of empirical research and standards of validation. The system presented demonstrates the challenges and opportunities inherent in developing and using AI-collaborative technology to solve social problems.


IPv6 over Low power Wireless Personal Area Networks, also known as 6LoWPAN, is becoming more and more a de facto standard for such communications for the Internet of Things, be it in the field of home and building automation, of industrial and process automation, or of smart metering and environmental monitoring. For all of these applications, scalability is a major precondition, as the complexity of the networks continuously increase. To maintain this growing amount of connected nodes a various 6LoWPAN implementations are available. One of the mentioned was developed by the authors' team and was tested on an Automated Physical Testbed for Wireless Systems at the Laboratory Embedded Systems and Communication Electronics of Offenburg University of Applied Sciences, which allows the flexible setup and full control of arbitrary topologies. It also supports time-varying topologies and thus helps to measure performance of the RPL implementation. The results of the measurements prove an excellent stability and a very good short and long-term performance also under dynamic conditions. In all measurements, there is an advantage of minimum 10% with regard to the average times, like global repair time; but the advantage with reagr to average values can reach up to 30%. Moreover, it can be proven that the performance predictions from other papers are consistent with the executed real-life implementations.


An anomaly in legislation is absence of completeness, consistency and other desirable properties, caused by different semantic, syntactic or pragmatic reasons. In general, the detection of anomalies in legislation comprises validation and verification. The basic idea of research, as presented in this paper, is modelling legislation by capturing domain knowledge of legislation and specifying it in a generic way by using commonly agreed and understandable modelling concepts of the Unified Modelling Language (UML). Models of legislation enable to understand the system better, support the detection of anomalies and help to improve the quality of legislation by validation and verification. By implementing model-based approach, the object of validation and verification moves from legislation to its model. The business domain of legislation has two distinct aspects: a structural or static aspect (functionality, business data etc.), and a behavioural or dynamic part (states, transitions, activities, sequences etc.). Because anomalism can occur on two different levels, on the level of a model, or on the level of legislation itself, a framework for validation and verification of legal regulation and its model is discussed. The presented framework includes some significant types of semantic and syntactic anomalies. Some ideas for assessment of pragmatic anomalies of models were found in the field of software quality metrics. Thus pragmatic features and attributes can be determined that could be relevant for evaluation purposes of models. Based on analogue standards for the evaluation of software, a qualitative and quantitative scale can be applied to determine the value of some feature for a specific model.


Unlike many areas of international cooperation, international financial regulation (IFR) relies on informal networks of regulators and "soft law" standards. The conventional wisdom is that this system provides effective cooperation while preserving the benefits of speed, flexibility and expertise in regulating global financial markets. In light of the crisis, however, skepticism has grown, with some commentators calling for a formal international organization to regulate finance. An elementary difficulty in this debate is the lack of a convincing account of the objectives of IFR. Why is unilateral regulation by states suboptimal, what are the potential gains from cooperation, and are those gains in fact achieved?This article identifies five such objectives. The current system has been largely successful at two of them: facilitating basic cross-border supervision and enforcement assistance among regulators, and removing barriers to international finance by harmonizing some national rules. In three important areas, however, IFR has performed poorly. First, it has encountered numerous setbacks in its attempts to raise regulatory standards in states where powerful domestic constituencies resist reforms. Second, it has struggled to secure durable collective action among major jurisdictions to raise prudential standards, like capital adequacy rules. Finally, it has failed to create credible mechanisms to address situations where unilateral action is counterproductive, like cross-border bank resolution.Given such limited success, why do soft law and networks dominate IFR? This article argues that the current system is not a product of efficient design but of historical path dependence and political economy. The postwar monetary system contemplated strict limitations on capital mobility and no need for regulation of international finance. After it collapsed, national regulators had to face financial globalization with the limited tools at their disposal. In turn, the growth of informal IFR empowered political actors — the regulators themselves, financial firms, and great powers — whose interests now largely determine outcomes across areas of IFR. Despite some post-crisis reforms, this pattern persists and raises doubt that IFR can effectively address the challenges of systemic risk and moral hazard.


Abstract. This study presents a modeling framework based on laboratory data to describe the kinetics of glyoxal reactions that form secondary organic aerosol (SOA) in aqueous aerosol particles. Recent laboratory results on glyoxal reactions are reviewed and a consistent set of empirical reaction rate constants is derived that captures the kinetics of glyoxal hydration and subsequent reversible and irreversible reactions in aqueous inorganic and water-soluble organic aerosol seeds. Products of these processes include (a) oligomers, (b) nitrogen-containing products, (c) photochemical oxidation products with high molecular weight. These additional aqueous phase processes enhance the SOA formation rate in particles and yield two to three orders of magnitude more SOA than predicted based on reaction schemes for dilute aqueous phase (cloud) chemistry for the same conditions (liquid water content, particle size). The application of the new module including detailed chemical processes in a box model demonstrates that both the time scale to reach aqueous phase equilibria and the choice of rate constants of irreversible reactions have a pronounced effect on the predicted atmospheric relevance of SOA formation from glyoxal. During day time, a photochemical (most likely radical-initiated) process is the major SOA formation pathway forming ∼5 μg m−3 SOA over 12 h (assuming a constant glyoxal mixing ratio of 300 ppt). During night time, reactions of nitrogen-containing compounds (ammonium, amines, amino acids) contribute most to the predicted SOA mass; however, the absolute predicted SOA masses are reduced by an order of magnitude as compared to day time production. The contribution of the ammonium reaction significantly increases in moderately acidic or neutral particles (5 Glyoxal uptake into ammonium sulfate seed under dark conditions can be represented with a single reaction parameter keffupt that does not depend on aerosol loading or water content, which indicates a possibly catalytic role of aerosol water in SOA formation. However, the reversible nature of uptake under dark conditions is not captured by keffupt, and can be parameterized by an effective Henry's law constant including an equilibrium constant Kolig = 1000 (in ammonium sulfate solution). Such reversible glyoxal oligomerization contributes Sensitivity tests reveal five parameters that strongly affect the predicted SOA mass from glyoxal: (1) time scales to reach equilibrium states (as opposed to assuming instantaneous equilibrium), (2) particle pH, (3) chemical composition of the bulk aerosol, (4) particle surface composition, and (5) particle liquid water content that is mostly determined by the amount and hygroscopicity of aerosol mass and to a lesser extent by the ambient relative humidity. Glyoxal serves as an example molecule, and the conclusions about SOA formation in aqueous particles can serve for comparative studies of other molecules that form SOA as the result of multiphase chemical processing in aerosol water. This SOA source is currently underrepresented in atmospheric models; if included it is likely to bring SOA predictions (mass and O/C ratio) into better agreement with field observations.


Paul Lowe wrote the introductory text for this new publication by Simon Norfolk.

Simon Norfolk's 2002 book Afghanistan: chronotopia is now recognised as a classic of photography. It established Norfolk's reputation as one of the leading photographers in the world and has been exhibited at more than thirty venues worldwide.

In 2010 Simon Norfolk returned to Afghanistan. This time he followed in the footsteps of the nineteenth century Irish photographer John Burke, a superb, yet virtually unknown, war photographer. Burke's eloquent and beautiful photographs of the Second Anglo-Afghan War (1878-1880) provide an extraordinary record. Using unwieldy wet-plate collodion negatives and huge wooden cameras he shot landscapes, battle-fields, archaeological sites, street scenes, portraits of British officers and ethnological group portraits of Afghans in what amounts to a record of an Imperial encounter. The range is tremendously broad, yet suffused with a delicate humanism. These are also amongst the first ever pictures made in Afghanistan. With this book, one hundred and thirty years too late, John Burke's time has come at last.

Norfolk's new work looks at what happens when you add half a trillion US war dollars to an impoverished and broken country such as Afghanistan. Very loosely re-photographic in nature, the work is presented as an artistic collaboration between Burke and Norfolk. It features photographs by Burke never before published as well as Norfolk's new pictures from Kabul and Helmand.

Simon Norfolk has received innumerable awards for his work including The European Publishers Award for Photography, The Olivier Rebbot Award (Foreign Press Club of America), and The Infinity Award (ICP, New York). His work is in major public and private collections throughout the world. His most recent exhibition, in March 2011, was shown at the Queen's Palace in the Barge Babur garden in Kabul. Supported by The World Collections Programme and the Aga Khan Trust for Culture, it incorporated both Norfolk and Burke's photographs alongside work resulting from a series of workshops by Simon Norfolk with Afghan photographers.


The role of tidal processes on intertidal surface sediments is frequently stated but rarely investigated due to the methodological restrictions. This study provides a basis for describing the tidal effects on the mangrove sediment. It reports investigations into the chemical composition of mangrove surface sediment in Mengkabong lagoon, Sabah, Malaysia. The levels of 16 parameters were determined in 33 surface sediment samples at high and low tides. The studied parameters showed high values at high tide compared to low tide. The tidal process showed there is a high contribution of seawater that brings additional ions such as Na, Mg and K into the mangrove system at high tide whereas at low tide, lower contribution of seawater was observed. Spearman correlation coefficient was used for the statistical characterizations of mangrove surface sediment at high and low tides. Relationships between physicochemical parameters, metals, granulometric fractions, organic matter and base cations at high and low tides were observed. Geoaccumulation Index calculations showed current sediment quality of Mengkabong mangrove sediments could be classified as having background concentrations of Al, Cu, Fe, and Zn, and as unpolluted with regard to Pb. These findings are important for future research which will explain the chemistry that lies in mangrove sediment.


'The best business book I've ever read.' Bill Gates, Wall Street Journal 'The Michael Lewis of his day.' New York Times What do the $350 million Ford Motor Company disaster known as the Edsel, the fast and incredible rise of Xerox, and the unbelievable scandals at General Electric and Texas Gulf Sulphur have in common? Each is an example of how an iconic company was defined by a particular moment of fame or notoriety. These notable and fascinating accounts are as relevant today to understanding the intricacies of corporate life as they were when the events happened. Stories about Wall Street are infused with drama and adventure and reveal the machinations and volatile nature of the world of finance. John Brooks's insightful reportage is so full of personality and critical detail that whether he is looking at the astounding market crash of 1962, the collapse of a well-known brokerage firm, or the bold attempt by American bankers to save the British pound, one gets the sense that history really does repeat itself. This business classic written by longtime New Yorker contributor John Brooks is an insightful and engaging look into corporate and financial life in America.

The first part of the article evaluates Summers' writings on the importance of democracy in the labor movement. The second part describes Summers' work as both a scholar and public policy activist shaping the law of union democracy, including his critical role in the drafting of the Labor-Management Reporting and Disclosure Act of 1959. The final part of the article examines Summers contributions to the creation of a movement, embodied in the Association for Union Democracy, to promote democratic unionism. It also describes his continuing efforts, through his scholarship and his advocacy, to implement and further develop the field of law he helped to create.


We researched the infrastructure and current medical data management systems in Vietnam and designed an electronic medical record keeping system to acquire, process, store and share health information in a fully automated computer network-based system. The modules in the system have automated data acquisition from Ultrasound, Digital Radiography, CT scanner, MRI and Laboratory stations, and manage pharmacy and financial information and other related activities in the hospital. Database servers currently store personal information along with text data, image data and will store video data in the future. The system will allow the patient to login and review online their medical records at home. The system was tested in the Biomedical Informatics Laboratory at the Hanoi University of Science and Technology and implemented in Khanh Luong hospital in Hanoi, Vietnam. It meets the needs for healthcare in developing countries with low investment cost, ease of implementation, and convenience for doctors and medical staff.


The standard of education among the Orang Asli people as an indigenous ethnic in Malaysia is still at a low level. The majority of the Orang Asli people receive formal education only at the primary level. However, there is a significant trend where the majority of students who completed their primary education will drop out from secondary school. Hence, only two percent have been successful in advancing their higher education in tertiary institutions. Such problems are commonly associated with several factors, including students' attitudes, awareness among parents about education, local culture, school leadership, school environment, and problems related to the teaching and learning process. For better understanding of this problem, a specific research was carried out to study the Orang Asli students in Kelantan. The research focused on students' perspectives based on the questions: What are the teaching and learning methods often used by teachers? What are the common problems related to the teaching and learning of the Orang Asli students? What are students' perceptions toward the teaching and learning methods used? The research using qualitative methods involved four Orang Asli villages in the state of Kelantan. Data were collected through interviews, focus group discussion and observation. The respondents consisted of children and young adults. Results showed that teaching pedagogy are generally stereotyped and unable to stimulate students' interest. The common problem in the teaching and learning is related to the attitude and commitment of teachers in the teaching and learning process. The implications of the problems and teachers' attitudes are significantly associated with degrading interest among students on education, issues of attendance and students' academic performance.

This paper explores an approach to creating an online tutorial to support postgraduate distance learners in the School of Geography at the University of Leeds. The process used by the author, the subject librarian for geography, is described through the planning and design stages, to development and application, and finally evaluation and future uses of the tutorial. The aim of the tutorial was to provide a resource students could use to improve and develop their information literacy (IL) and academic skills, addressing the process of producing a written assignment, from planning, to search tools and techniques, to reading and critical thinking, through to writing up and referencing. In planning and designing the tutorial, the content covered in the face-to-face workshop for postgraduate students on finding, managing and evaluating information was reviewed, and information on Library support for distance learners added. To accommodate differing learning styles, and encourage learning by doing, activities such as drag-and-drop exercises, quizzes and videos were used. A learning technologist was consulted for advice on look and feel, navigation and techniques to improve interactivity. The tutorial was made available via the VLE and students were encouraged by their tutor to look at the tutorial and fill in a short feedback survey. Obtaining qualitative feedback from students in an online environment proved challenging, and ultimately was a major limitation in providing a thorough evaluation of the tutorial. There were also difficulties in obtaining quantitative data on use of the tutorial. With little evidence of whether the tutorial had been helpful to students, or had enabled them to improve their information literacy skills, decisions as to its continuation had to be made based on feedback from academic staff and the perceived benefits, identified by library staff, of reusing the tutorial as a resource to support face-to-face workshops. While not every IL practitioner will have access to the software used (Articulate), or have the assistance of a learning technologist, the principles of developing online tutorial learning materials, the advice from the learning technologist, and the explanation of limitations and lessons learned will be of interest to any library professional or IL practitioner wishing to create online learning resources.

This thesis deals with the relationship between no-arbitrage and (strictly) consistent price processes for a financial market with proportional transaction costs
in a discrete time model. The exact mathematical statement behind this relationship is formulated in the so-called Fundamental Theorem of Asset Pricing (FTAP). Among the many proofs of the FTAP without transaction costs there
is also an economic intuitive utility-based approach. It relies on the economic
intuitive fact that the investor can maximize his expected utility from terminal
wealth. This approach is rather constructive since the equivalent martingale measure is then given by the marginal utility evaluated at the optimal terminal payoff.
However, in the presence of proportional transaction costs such a utility-based approach for the existence of consistent price processes is missing in the literature. So far, rather deep methods from functional analysis or from the theory of random sets have been used to show the FTAP under proportional transaction costs.
For the sake of existence of a utility-maximizing payoff we first concentrate on a generic single-period model with only one risky asset. The marignal utility evaluated at the optimal terminal payoff yields the first component of a
consistent price process. The second component is given by the bid-ask prices
depending on the investors optimal action. Even more is true: nearby this consistent price process there are many strictly consistent price processes. Their exact structure allows us to apply this utility-maximizing argument in a multi-period model. In a backwards induction we adapt the given bid-ask prices in such a way so that the strictly consistent price processes found from maximizing utility can be extended to terminal time. In addition possible arbitrage opportunities of the 2nd kind vanish which can present for the original bid-ask process. The notion of arbitrage opportunities of the 2nd kind has been so
far investigated only in models with strict costs in every state. In our model
transaction costs need not be present in every state.
For a model with finitely many risky assets a similar idea is applicable. However, in the single-period case we need to develop new methods compared
to the single-period case with only one risky asset. There are mainly two reasons
for that. Firstly, it is not at all obvious how to get a consistent price process
from the utility-maximizing payoff, since the consistent price process has to be
found for all assets simultaneously. Secondly, we need to show directly that the
so-called vector space property for null payoffs implies the robust no-arbitrage condition. Once this step is accomplished we can a priori use prices with a
smaller spread than the original ones so that the consistent price process found
from the utility-maximizing payoff is strictly consistent for the original prices.
To make the results applicable for the multi-period case we assume that the prices are given by compact and convex random sets. Then the multi-period case is similar to the case with only one risky asset but more demanding with regard to technical questions.


This paper presents a completely systematic design procedure for asynchronous controllers.The initial step is the construction of a signal transition graph (STG, an interpreted Petri net) ofthe dialog between data path and controller: a formal representation without reference to timeor internal states. To implement concurrently operating control structures, and also to reducedesign effort and circuit cost, this STG can be decomposed into overlapping subnets. A univer-sal initial solution is then obtained by algorithmically constructing a primitive flow table fromeach component net. This step links the procedure to classical asynchronous design, in particu-lar to its proven optimization methods, without restricting the set of solutions. In contrast toother approaches, there is no need to extend the original STG intuitively.


Background and aims: Functional magnetic resonance imaging (fMRI) offers comprehensive information on brain function. The objective fMRI data can be correlated with behavioural and clinical measures to help dissect a subjective pain experience into its components. In this study we compared changes of experimental and clinical pain processing in rheumatoid arthritis (RA) before and after treatment with etanercept or infliximab; agents that block the action of proinflammatory cytokine, tumor necrosis factor (anti-TNF). Methods: We recruited 10 patients with active rheumatoid arthritis (RA) due to begin the anti-TNF treatment and 10 age and sex matched healthy volunteers. We used fMRI to investigate changes in brain activation patterns in response to clinically-relevant stimuli (joint squeeze and experimental heat pain stimulation) pre- and post-treatment. We collected also clinical and psychophysical information from each patient. Results: We observed robust activation in response to both clinical and experimental pain in all major pain processing areas. Preliminary analysis suggests that fMRI is able to detect differences in experimental pain processing between patients and healthy subjects, as well as differences between clinical and experimental pain in RA patients alone. We found significant (p<0.05) decreases in pain ratings for both kinds of stimuli, clinical markers of inflammation, disease activity score (DAS 28) and significant changes in fMRI signal in insula cortex post anti-TNF treatment. Conclusions: Our findings suggest that fMRI is a sensitive measure of pain experience and has the potential to become a useful tool in understanding pathophysiology of chronic pain as well as measuring treatment effects.


The Ozone Monitoring Instrument (OMI) aboard EOS-Aura and the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard EOS-Aqua fly in formation as part of the A-train. Though OMI retrieves aerosol optical depth (AOD) and aerosol absorption, it must assume aerosol layer height. The MODIS cannot retrieve aerosol absorption, but MODIS aerosol retrieval is not sensitive to aerosol layer height and with its smaller pixel size is less affected by subpixel clouds. Here we demonstrate an approach that uses MODIS-retrieved AOD to constrain the OMI retrieval, freeing OMI from making an a priori estimate of aerosol height and allowing a more direct retrieval of aerosol absorption. To predict near-UV optical depths using MODIS data we rely on the spectral curvature of the MODIS-retrieved visible and near-IR spectral AODs. Application of an OMI-MODIS joint retrieval over the north tropical Atlantic shows good agreement between OMI and MODIS-predicted AODs in the UV, which implies that the aerosol height assumed in the OMI-standard algorithm is probably correct. In contrast, over the Arabian Sea, MODIS-predicted AOD deviated from the OMI-standard retrieval, but combined OMI-MODIS retrievals substantially improved information on aerosol layer height (on the basis of validation against airborne lidar measurements). This implies an improvement in the aerosol absorption retrieval, but lack of UV absorption measurements prevents a true validation. Our study demonstrates the potential of multisatellite analysis of A-train data to improve the accuracy of retrieved aerosol products and suggests that a combined OMI-MODIS-CALIPSO retrieval has large potential to further improve assessments of aerosol absorption.


Objective – To determine whether and how Danish university and higher education students use public libraries for study purposes.

Design – Online survey.

Setting – Post-secondary students in Denmark.

Subjects – 1,575 students in university-level programs or other higher education programs (vocational three-to-four-year programs) in Denmark.

Methods – A sample of students was drawn from the national database of students by selecting every student born on the 15th of every month (approximately 4,900 students). A letter describing the study and with an invitation to fill out an online questionnaire was sent to all students in the sample. There were 1,694 valid responses (approximately 35% response rate). Students following short vocational programs were deemed to be under-represented and these subjects were omitted from the analysis of this report, which reflects the response of 1,575 students.

The online questionnaire gathered demographic details (gender, age, educational institution, study topic, study year, geographical location, access to the Internet, etc.) and used 110 questions or statements to gather information about student information-seeking behaviour related to study purposes. These included use of the physical library and satisfaction with services, use of search engines, awareness and use of library Web-based services, study behaviour, and participation in information literacy activities.

Main results – For the purposes of this study, "academic library is used as a generic term covering university libraries, research libraries, educational libraries and all other kind of libraries outside the field of public libraries" (p. 278).
The survey results confirmed many of the previous international reports of student information-seeking behaviour: 85% of students use the academic library for study purposes; fewer than 10% of all students are able to cope without any library use; students in technology and engineering, the sciences and arts, architecture and music have a higher rate of non-use of their academic libraries; a large percentage of students access the electronic resources from home; the physical library is still considered important to students; Google is used extensively and is nearly the exclusive choice for search engine.

The public library is used for study purposes by about 58 percent of all students with the highest use (76%) by students in higher education institutions (HEI); students of education, social topics and psychology are very frequent public library users. Female students in HEI were the most frequent users of the public library independent of study subject or year, or any other demographic variable. Seven per cent of students rely exclusively on the public library for study purposes and first-year HEI students in the subject areas of education, social topics and psychology are over-represented in this group (which additionally has less Internet access from home than the other students).

Students perceive nearly all aspects of service in the academic library as superior; HEI students rate ambience, electronic resources and speed of inter-library loan provision in the public library as higher than the academic.

University students give a low rating to the collections of public library, although the students use the public library principally to supplement the collections available in their academic libraries. Another high use of public libraries by HEI students is for inter-library loans placed through the national resource sharing system. Public library reference services are used often by only one per cent of students and only two per cent use the public library on a regular basis for "study related group activities."

Conclusion – Students use physical libraries to a great extent to support their studies and students have embraced digital access to collections, especially access from home. Google is the most heavily used search engine and is used by nearly all students; use of Google complements and supplements library use.
Nearly 60% of all students use public libraries for study purposes and to supplement the collections of their academic library, but they find that the public library collections are insufficient to meet their needs. The inter-library loan policies of public libraries are more lenient and accommodating to student needs and may drive the high use of public libraries. Students form a large constituency of the public library user population and they generally rate most aspects of service as substandard to those of academic libraries. There is a call for review of the public library's role in meeting the information needs of students, and in particular, those of HEI programs who are most dependent on the public library.


Recent studies on African economic history have emphasized the structural impediments to African growth, such as adverse geographical conditions and extractive colonial institutions. The evidence is mainly drawn from cross-country regressions on late 20th century income levels, assuming persistent effects of historical causes over time. But to which extent has African poverty been a persistent phenomenon? Our study sheds light on this question by providing new evidence on long-term African growth-trajectories. We show that slave trade regressions are not robust for pre-1970s GDP per capita levels, or for pre-1973 and post-1995 growth rates. We calculate urban unskilled real wages of African workers in nine British African countries 1880-1965, adopting Allen's (2009) subsistence basket methodology. We find that real wages were above subsistence level, rose significantly over time and were, in major parts of British Africa, considerably higher than real wages in Asian cities up to, at least the 1930s. We explain the intra-African variation in real wage levels by varying colonial institutions concerning land alienation, taxation and immigration.


The quintessential city park symbolizes a core feature of a democratic polity: the freedom of all citizens to express their views in public spaces free from the constraints of government imposed orthodoxy. The city park finds an unlikely cousin in the federal tax code's recognition of deductions for contributions made to charitable, religious, and educational organizations. Together, these three categories of tax-exempt organizations encompass a vast array of groups in civil society. The resulting mosaic is neither thematic nor tidy, but it is in at least one sense, beautiful: the deductions, like the city park, enact the aspirations of a democratic polity. Organizations and ideas wither or thrive not by government fiat but based on the "values and choices of private givers." The city park is a traditional public forum under First Amendment doctrine, and the charitable, educational, and religious deductions under the federal tax code function much like a limited public forum. Between these poles lie numerous other governmental arrangements with similar purposes and functions: sidewalks, parking lots, public schools, websites, public libraries, vanity license plates, and student activity funds, to name a few. In each of these cases, private groups and individuals rely on government resources (financial or otherwise) to inculcate and express their ideas and their ways of life. The ideal of the public forum represents one of the most important aspects of a healthy democracy. It signifies a willingness to tolerate dissent, discomfort, and even instability. The distortion of that ideal represents one of the greatest challenges to First Amendment jurisprudence today. That distortion is partially attributable to two important doctrinal developments. The first is increased judicial reliance on purportedly "content-neutral" time, place, and manner restrictions. The second is the relationship between the public forum and the evolving government speech doctrine, under which the government characterizes messages advanced under the auspices of its financial and other resources as distinctively its own and not subject to First Amendment review. This essay suggests that one factor facilitating these developments is a gradual but unmistakable shift in the moorings of the public forum doctrine from the Assembly Clause to the Speech Clause. The public forum is a First Amendment doctrine, not a free speech doctrine. And we will only comprehend its purposes and its possibilities when we rediscover the values underlying the rights of the First Amendment.


On August 15, 1914, the Panama Canal officially opened for business, forever changing the face of global trade and military power, as well as the role of the United States on the world stage. The Canal's creation is often seen as an example of U.S. triumphalism, but Noel Maurer and Carlos Yu reveal a more complex story. Examining the Canal's influence on Panama, the United States, and the world, The Big Ditch deftly chronicles the economic and political history of the Canal, from Spain's earliest proposals in 1529 through the final handover of the Canal to Panama on December 31, 1999, to the present day. The authors show that the Canal produced great economic dividends for the first quarter-century following its opening, despite massive cost overruns and delays. Relying on geographical advantage and military might, the United States captured most of these benefits. By the 1970s, however, when the Carter administration negotiated the eventual turnover of the Canal back to Panama, the strategic and economic value of the Canal had disappeared. And yet, contrary to skeptics who believed it was impossible for a fledgling nation plagued by corruption to manage the Canal, when the Panamanians finally had control, they switched the Canal from a public utility to a for-profit corporation, ultimately running it better than their northern patrons. A remarkable tale, The Big Ditch offers vital lessons about the impact of large-scale infrastructure projects, American overseas interventions on institutional development, and the ability of governments to run companies effectively.


Based on dual process models of information processing, the present research addressed how explicit disgust sensitivity is re-adapted according to implicit disgust sensitivity via self-perception of automatic behavioral cues. Contrary to preceding studies (Hofmann, Gschwendner, & Schmitt, 2009) that concluded that there was a "blind spot" for self- but not for observer perception of automatic behavioral cues, in the present research, a re-adaption process was found for self-perceivers and observers. In Study 1 (N = 75), the predictive validity of an indirect disgust sensitivity measure was tested with a double-dissociation strategy. Study 2 (N = 117) reinvestigated the hypothesis that self-perception of automatic behavioral cues, predicted by an indirect disgust sensitivity measure, led to a re-adaption of explicit disgust sensitivity measures. Using a different approach from Hofmann et al. (2009), the self-perception procedure was modified by (a) feeding back the behavior several times while a small number of cues had to be rated for each feedback condition, (b) using disgust sensitivity as a domain with clearly unequivocal cues of automatic behavior (facial expression, body movements) and describing these cues unambiguously, and (c) using a specific explicit disgust sensitivity measure in addition to a general explicit disgust sensitivity measure. In Study 3 (N = 130), the findings of Study 2 were replicated and display rules and need for closure as moderator effects of predictive validity and cue utilization were additionally investigated. The moderator effects give hints that both displaying a disgusted facial expression and self-perception of one- own disgusted facial expression are subject to a self-serving bias, indicating that facial expression may not be an automatic behavior. Practical implications and implications for future research are discussed.


Time-Series clustering is one of the important concepts of data mining that is used to gain insight into the mechanism that generate the time-series and predicting the future values of the given time-series. Time-series data are frequently very large and elements of these kinds of data have temporal ordering. The clustering of time series is organized into three groups depending upon whether they work directly on raw data either in frequency or time domain, indirectly with the features extracted from the raw data or with model built from raw data. In this paper, we have shown the survey and summarization of previous work that investigated the clustering of time series in various application domains ranging from science, engineering, business, finance, economic, health care, to government.


Increasing environmental problems, including those associated with climate change, highlight the need for land conservation. Dissatisfaction with public methods of environmental protection has spurred conservationists to pursue private options. One of the most common private land conservation tools is the conservation easement. At first blush, this relatively new servitude appears to provide a creative method for achieving widespread conservation. Instead, however, conservation easements often fail to accommodate the reality of our current environmental problems. These perpetual (often private) agreements lack flexibility, making them inappropriate tools for environmental protection in the context of climate change and our evolving understanding of conservation biology. This article addresses concerns with the widespread use of conservation easements, advocating for improved conservation easements and better decision making as to when to use conservation easements. A first step in rethinking our approach to the use of conservation easements is to shift from perpetual conservation easements to renewable term conservation easements. Although perpetuity is one of the defining aspects of most conservation easements, it is neither realistic nor desired. In their current static form, conservation easements are not receptive to change in ecology or society. Where conservation easements are of a limited duration, their economic, societal, and conservation value can be more readily assessed and considered when making land-use decisions. Additionally, many conservation easements are already beset with durability concerns. Instead of forcing a cumbersome and unrealistic perpetuity requirement on conservation easements, we should use agreements with a revisitation date. By shifting the initial assumption that these agreements will not be perpetual, we can create responsive agreements and make better decisions regarding when conservation easements are appropriate.


Spatial data infrastructure (SDI) is the infrastructure that facilitates the discovery, access, management, distribution, reuse, and preservation of digital geospatial resources. These resources may include maps, data, geospatial services, and tools. As cyberinfrastructures, SDIs are similar to other infrastructures, such as water supplies and transportation networks, since they play fundamental roles in many aspects of the society. These roles have become even more significant in today's big data age, when a large volume of geospatial data and Web services are available. From a technological perspective, SDIs mainly consist of data, hardware, and software. However, a truly functional SDI also needs the efforts of people, supports from organizations, government policies, data and software standards, and many others. In this chapter, we will present the concepts and values of SDIs, as well as a brief history of SDI development in the U.S. We will also discuss the components of a typical SDI, and will specifically focus on three key components: geoportals, metadata, and search functions. Examples of the existing SDI implementations will also be discussed.


Phenytoin is a well-known antiepileptic agent widely used throughout the world. Recent clinical studies in patients with bipolar disorder have suggested that, as for other anticonvulsant drugs commonly used in the treatment of bipolar patients including valproate and carbamazepine, phenytoin may have mood-stabilizing effects in addition to its well-known anticonvulsant properties. In a study published on page 300 of this issue of Experimental Biology and Medicine Veronica Mariotti and colleagues utilized DNA microarrays to investigate the molecular underpinnings of the potential mood-stabilizing action of phenytoin by looking at its effect on gene expression in the rat brain. As compared with untreated animals, rats treated for a month with phenytoin had 508 differentially expressed genes in the hippocampus and 62 in the frontal cortex, including genes involved in GABAergic and glutamatergic neurotransmission, neuroprotection and other genes thought to be crucial for mood regulation. Furthermore, some of these same genes have been shown to be modulated by classical mood-stabilizer agents, like lithium and valproate. Thus, the findings of this study indicate that chronic phenytoin administration modulates the expression of genes involved in mood regulation and genes that are targets of established mood stabilizers. Dr Mariotti noted that 'The results of this study provide preliminary insights into possible molecular mechanisms of action of phenytoin as a potential mood stabilizer and, more in general, the pathophysiology of bipolar disorders'. The study is the product of a fruitful collaboration between the Molecular Biology Laboratory of Dr Silvia Pellegrini at the Department of Experimental Pathology, University of Pisa Medical School, Pisa, Italy and the Laboratory of Professors Galila Agam and RH Belmaker at the Psychiatry Research Unit at the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel. Dr Steven R Goodman, Editor-in-Chief of Experimental Biology and Medicine, said 'Mariotti and colleagues have provided very interesting results on the changes in gene expression in rats treated with phenytoin. Their findings shed significant light on the mood altering effects of this antiepileptic drug'.


This edited volume provides a critical review of political communication research conducted in Asia over the past twenty years. Each chapter focuses on studies published in a specific Asian country, selected according to the level of contribution made to the field of political communication in Asia. Covering China, Hong Kong, Taiwan, South Korea, Japan, Singapore, Malaysia, Indonesia, and India, the book's primary objective is to review the unique theoretical accomplishments made by Asian communication scholars, thus contributing to a better awareness and understanding of political communication research in Asia.

The contributors are well-respected Asian media scholars writing on political communication in their countries of origin. Each author reviews studies conducted and published in his/her native country and language(s). This book provides a first review of these studies, most of which have never been published in English, and makes them available to international scholars. The contributors discuss each country's political background, and address the findings and conclusions of the political communication studies conducted in their respective countries during the past two decades. The chapters focus on insights that have been made by adapting Western media theories to the unique social, cultural, or political contexts that exist in each country. The authors also point out possible gaps in the current research within their respective countries and to make recommendations for future studies.


The death penalty today provides virtually none of the benefits its advocates proffer as justifications for its existence. The tiny number of death sentences imposed, the even tinier number actually carried out, the enormous drain on public resources, and the decade-long delays that inevitably occur thoroughly undermine any deterrent or retributive benefits today's death penalty might otherwise provide. In this paper, I argue for a compromise position that promises to better serve penal purposes and that will save states money at the same time: abandon the current dysfunctional death penalty in favor of a new ultimate sentence: death-in-prison. A sentence of death-in-prison would be exactly what it says: a prisoner sentenced to death-in-prison would remain in prison until he or she died. Death-in-prison would be a kind of hybrid sentence: like life in prison without possibility of parole ("LWOP"), death-in-prison would entail lifetime incarceration but no affirmative state action to terminate the prisoner's life, but death-in-prison would also share several features of the conventional death penalty. As with the conventional death penalty, a special penalty trial would be needed to impose the ultimate death-in-prison sentence. In addition, persons sentenced to death-in-prison might continue to serve their sentences in special segregated "death rows." Death-in-prison sentences would also be imposed with all the magisterial weightiness of conventional death sentences. Persons so sentenced would be told, like those in conventional death penalty states, that the punishment for their crime is the ultimate one — death. If adopted, death-in-prison would reduce criminal justice expenditures, facilitate community healing, discourage divisive and ineffective commutation campaigns, and diminish wrongful executions, without forgoing what is arguably the greatest benefit of the current death penalty: the expressive value of imposing a "death" rather than a "life" sentence on highly culpable offenders.


[1] A cloud frequency of occurrence matrix is generated using merged cloud vertical profiles derived from the satellite‐borne Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) and cloud profiling radar. The matrix contains vertical profiles of cloud occurrence frequency as a function of the uppermost cloud top. It is shown that the cloud fraction and uppermost cloud top vertical profiles can be related by a cloud overlap matrix when the correlation length of cloud occurrence, which is interpreted as an effective cloud thickness, is introduced. The underlying assumption in establishing the above relation is that cloud overlap approaches random overlap with increasing distance separating cloud layers and that the probability of deviating from random overlap decreases exponentially with distance. One month of Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and CloudSat data (July 2006) support these assumptions, although the correlation length sometimes increases with separation distance when the cloud top height is large. The data also show that the correlation length depends on cloud top hight and the maximum occurs when the cloud top height is 8 to 10 km. The cloud correlation length is equivalent to the decorrelation distance introduced by Hogan and Illingworth (2000) when cloud fractions of both layers in a two‐cloud layer system are the same. The simple relationships derived in this study can be used to estimate the top‐of‐atmosphere irradiance difference caused by cloud fraction, uppermost cloud top, and cloud thickness vertical profile differences.


Experiments and theory in single trophic level systems dominate biodiversity and ecosystem functioning research and recent debates. All natural ecosystems contain communities with multiple trophic levels, however, and this can have important effects on ecosystem structure and functioning. Furthermore, many experiments compare assembled communities, rather than examining loss of species directly. We identify three questions around which to organise an investigation of how species loss affects the structure and functioning of multitrophic systems. 1) What is the distribution of species richness among trophic levels; 2) from which trophic levels are species most often lost; and 3) does loss of species from different trophic levels influence ecosystem functioning differently? Our analyses show that: 1) Relatively few high-quality data are available concerning the distribution of species richness among trophic levels. A new data-set provides evidence of a decrease in species richness as trophic height increases. 2) Multiple lines of evidence indicate that species are lost from higher trophic levels more frequently than lower trophic levels. 3) A theoretical model suggests that both the structure of food webs (occurrence of omnivory and the distribution of species richness among trophic levels) and the trophic level from which species are lost determines the impact of species loss on ecosystem functioning, which can even vary in the sign of the effect. These results indicate that, at least for aquatic systems, models of single trophic level ecosystems are insufficient for understanding the functional consequences of extinctions. Knowledge is required of food web structure, which species are likely to be lost, and also whether cascading extinctions will occur.


The European Union (EU), comprised of 15 member states (countries), is one of the United States' chief agricultural trading partners and also a major competitor in world markets. Both heavily support their agricultural sectors, with a large share of such support concentrated on wheat, feed grains, cotton, oilseeds, sugar, dairy, and tobacco. However, the EU provides more extensive support to a broader range of farm and food products. According to the Organization for Economic Cooperation and Development (OECD), the EU and United States in 2001 together accounted for nearly two-thirds of all government support to agriculture among the major developed economies. However, EU agricultural spending generally is much higher than in the United States. Information comparing how the U.S. and EU governments support their producers is expected to be of interest to policymakers while negotiations are underway among world trading partners to further reform agricultural trade.


BACKGROUND
Evidence suggests that Latina women appear to be less physically active than women of other racial/ethnic groups. This study evaluated how different domains of physical activity (PA) contributed to overall levels of PA among low-income Latinas, the validity of Latinas' self-reported PA, and potential moderators of self-report bias in PA.

METHODS
A community sample of 105 Latinas (mean age = 35.9 ± 9.0 years; mean body mass index = 31.6 ± 7.2) completed the long form Spanish-language version of the International Physical Activity Questionnaire (IPAQ), wore an accelerometer for seven days, and completed self-reported measures of acculturation and socioeconomic status.

RESULTS
Ninety-six percent of IPAQ-reported moderate-intensity PA (MPA) was accrued during household activities, with only 4% accrued during leisure time. Seventy-two percent of participants met national recommendations for PA using IPAQ data, but only 20% met recommendations when measured by accelerometer. When bouts of MPA lasting >10 min were included, 0% met recommendations. Age appeared to moderate self-report bias of vigorous PA, and there were nonsignificant trends for acculturation and income to moderate MPA and vigorous-intensity PA, respectively.

CONCLUSIONS
Data suggest that it is important to measure household activity of Latinas, and that the IPAQ yield overestimates of self-report PA.


Background/Context School desegregation has been variably conceptualized as a remedy for racial injustice, a means toward urban (economic) revitalization, an opportunity to celebrate human diversity, and an attempt to more equally distribute educational resources. At the center of the debate over the years is the extent to which school desegregation is a matter of class or race, of redistribution or recognition. A cultural political economy of school desegregation begins with a rejection of the popular notion that desegregation is simply, or even primarily, about race. It also eschews the idea that what is needed is a "corrective" interjection of social class and economic justice. In proposing neither a racial nor an economic solution, cultural political economy sheds doubt on the very proposition of a "racial" or "economic" analysis, politics, or remedy and helps us more powerfully explain how the cultural and material force of race and class breathes as one through the historical-political trajectory of school desegregation. Purpose/Objective/Research Question/Focus of Study This article is based on findings from a larger historical-ethnographic research project intended to explicate the cultural-ideological and structural context(s) within which Seattle's Black leaders, educators, and activists made sense of the relationship between school desegregation and the lives and liberation of Black people in the post-civil-rights era. Here, the author uses cultural political economy as an analytical framework to elucidate the relationship(s) between cultural productions such as the construction of rights, justice, and racial progress, and political-economic formations such as the (ab)use of the state and market by certain classes—in this case, middle-class and affluent White Seattleites—to preserve their own privilege through the implementation of social and educational policies that serve to reproduce material inequities. Setting The study setting is Seattle, Washington. Population/Participants Black leaders, educators, and activists who participated in the school desegregation struggle in the city of Seattle from the mid-1970s through 2007. Research Design This study employed semistructured ethnographic interviews, content analysis, and historical/archival analysis. Conclusion/Recommendations The trajectory of school desegregation politics in Seattle, culminating in the U.S. Supreme Court ruling in Parents Involved in Community Schools v. Seattle School District No. 1, reveals a long and systematic political effort to delegitimize and dismantle justice-oriented redistribution of educational resources along racial lines. Cultural political economy provides an analytical framework that contributes to our theoretical understanding of the interimbrication of culture and political economy in education politics and policy-making. The author argues that understanding the interimbrication of class and race in the politics of school desegregation allows us to more clearly theorize how school desegregation policies are undermined in ways that reproduce material and cultural relations of power. Ultimately, critical researchers, educators, and youth and community activists must develop political strategies to shift the very relations of power highlighted in the Seattle case.

Capelli's identity plays a prominent role in Weyl's approach to Classical Invariant Theory. Capelli's identity was recently considered by Howe and Howe and Umeda. Howe gave an insightful representation-theoretic proof of Capelli's identity, and a similar approach was used to prove Turnbull's symmetric analog, as well as a new anti-symmetric analog, that was discovered independently by Kostant and Sahi. The Capelli, Turnbulll, and Howe-Umeda-Kostant-Sahi identities immediately imply, and were inspired by, identities of Cayley, Garding, and Shimura, respectively. In this paper, we give short combinatorial proofs of Capelli's and Turnbull's identities, and raise the hope that someone else will use our approach to prove the new Howe-Umeda-Kostant-Sahi identity.


Background: Self-medication, practiced globally is an important public health problem. Research studies have indicated inappropriate self‐medication results in adverse drug reactions, disease masking, antibiotic resistance and wastage of healthcare resources. The objectives of the study were to explore overall self-medication and antibiotic self-medication prevalence among students of university students in Karachi, Pakistan along with probable reasons, indications, and sources of advice for self-medication. Methods: A descriptive, cross-sectional, questionnaire-based study was carried out among students from university of Karachi, Pakistan during the time period of September to November 2016. Pretested questionnaire was distributed to 320 students, collected data was analyzed using IBM SPSS version 24. Results: From 320 students, 311 (83 male and 228 female) students participated in the study giving a response rate of 97%. Prevalence of self-medication was 66%. Belonging to higher monthly family income group was associated with likelihood of self-medication. Antibiotic self-medication prevalence was 39%. Lack of time (39%), and old prescription (35%) were the main reasons for self-medication. Pharmacy shop (75%) was the main source for self-medication. In case of antibiotics, 44% students changed the dosage of antibiotic and 50% students stopped antibiotics after the disappearance of the symptoms. Conclusions: Antibiotic self-medication (39%) and self-medication with other drugs among university students of Karachi is a worrisome problem. Our findings highlight the need for planning interventions to promote the judicious use of general medicines as well as that of antibiotics.


Rules are an important knowledge representation formalism in constructive problem solving. On the other hand, object orientation is an essential key technology for maintaining large knowledge bases as well as software applications. Trying to take advantage of the benefits of both paradigms, we integrated Prolog and Smalltalk to build a common base architecture for problem solving. This approach has proven to be useful in the development of two knowledge-based systems for planning and configuration design (CAPlan and Idax). Both applications use Prolog as an efficient computational source for the evaluation of knowledge represented as rules.


Addictive behavior threatens not just the addict's happiness and health but also the welfare and well-being of others. It represents a loss of self-control and a variety of other cognitive impairments and behavioral deficits. An addict may say, "I couldn't help myself." But questions arise: are we responsible for our addictions? And what responsibilities do others have to help us? This volume offers a range of perspectives on addiction and responsibility and how the two are bound together. Distinguished contributors -- from theorists to clinicians, from neuroscientists and psychologists to philosophers and legal scholars -- discuss these questions in essays using a variety of conceptual and investigative tools. Some contributors offer models of addiction-related phenomena, including theories of incentive sensitization, ego-depletion, and pathological affect; others address such traditional philosophical questions as free will and agency, mind-body, and other minds. Two essays, written by scholars who were themselves addicts, attempt to integrate first-person phenomenological accounts with the third-person perspective of the sciences. Contributors distinguish among moral responsibility, legal responsibility, and the ethical responsibility of clinicians and researchers. Taken together, the essays offer a forceful argument that we cannot fully understand addiction if we do not also understand responsibility.


When Jon Gruden asks his Tampa Bay Bucs, "Do you love football?!" it's to remind them why they pull on their shoulder pads every Sunday morning. It's not about the money or the fame; it's about their passion for what they do. And passion is something that has fueled Gruden's entire career. From his college playing days and his climb through the coaching ranks -- from college to assistant coaching jobs with the NFL's elite teams, to his first head coach job with the Oakland Raiders, and finally, with the Tampa Bay Bucs -- his meteoric rise is unparalleled. Underneath it all, though, he's just a humble, hardworking, no-nonsense guy who has no hobbies: "I'm not a scratch golfer. I don't know how to bowl. I can't read the stock market. Hell, I have a hard time remembering my wife's cell phone number. But I can call 'Flip Right Double X Jet 36 Counter Naked Waggle at 7 X Quarter' in my sleep." Now, in this motivational memoir, Gruden provides insight into what makes him tick. Do You Love Football?! is an intimate look at his life as a player, coach, and head coach, as well as the principles that have made him the hottest coach in the NFL.


outside of the catacombs, sufficiently sensible of conditions. Does anyone have the foggiest idea of what sort of power we so blithely invoke? Or, as I suspect, does no one believe a word of it? The churches are children playing on the floor with their chemistry sets, mixing up a batch of TNT to kill a Sunday morning. It is madness to wear ladies' straw hats and velvet hats to church; we should all be wearing crash helmets. Ushers should issue life preservers and signal flares; they should lash us to our pews. For the sleeping god may wake someday and take offense, or the waking god may draw us out to where we can never return.

Poetry doesn't matter to most people, observes Jay Parini at the opening of this book. But, undeterred, he commences a deeply felt meditation on poetry, its language and meaning, and its power to open minds and transform lives. By the end of the book, Parini has recovered a truth often obscured by our clamorous culture: without poetry, we live only partially, not fully conscious of the possibilities that life affords. Poetry indeed matters. A gifted poet and acclaimed teacher, Parini begins by looking at defenses of poetry written over the centuries. He ponders Aristotle, Horace, and Longinus, and moves on through Sidney, Wordsworth, Coleridge, Shelley, Eliot, Frost, Stevens, and others. Parini examines the importance of poetic voice and the mysteries of metaphor. He argues that a poet's originality depends on a deep understanding of the traditions of political poetry, nature poetry, and religious poetry. Writing with a casual grace, Parini avoids jargon and makes his case in concise, direct terms: the mind of the poet supplies a light to the minds of others, kindling their imaginations, helping them to live their lives. The author's love of poetry suffuses this insightful book--a volume for all readers interested in a fresh introduction to the art that lies at the center of Western civilization.


The work presented in this thesis discusses the model-based fault diagnosis and fault-tolerant control with application to a nonlinear electro-hydraulic system. High performance control with guaranteed safety and reliability for electro-hydraulic systems is a challenging task due to the high nonlinearity and system uncertainties. This thesis developed a diagnosis integrated fault-tolerant control (FTC) strategy for the electro-hydraulic system. In fault free case the nominal controller is in operation for achieving the best performance. If the fault occurs, the controller will be automatically reconfigured based on the fault information provided by the diagnosis system. Fault diagnosis and reconfigurable controller are the key parts for the proposed methodology. The system and sensor faults both are studied in the thesis. Fault diagnosis consists of fault detection and isolation (FDI). A model-base residual generating is realized by calculating the redundant information from the system model and available signal. In this thesis differential-geometric approach is employed, which gives a general formulation of FDI problem and is more compact and transparent among various model-based approaches. The principle of residual construction with differential-geometric method is to find an unobservable distribution. It indicates the existence of a system transformation, with which the unknown system disturbance can be decoupled. With the observability codistribution algorithm the local weak observability of transformed system is ensured. A Fault detection observer for the transformed system can be constructed to generate the residual. This method cannot isolated sensor faults. In the thesis the special decision making logic (DML) is designed based on the individual signal analysis of the residuals to isolate the fault. The reconfigurable controller is designed with the backstepping technique. Backstepping method is a recursive Lyapunov-based approach and can deal with nonlinear systems. Some system variables are considered as ``virtual controls'' during the design procedure. Then the feedback control laws and the associate Lyapunov function can be constructed by following step-by-step routine. For the electro-hydraulic system adaptive backstepping controller is employed for compensate the impact of the unknown external load in the fault free case. As soon as the fault is identified, the controller can be reconfigured according to the new modeling of faulty system. The system fault is modeled as the uncertainty of system and can be tolerated by parameter adaption. The senor fault acts to the system via controller. It can be modeled as parameter uncertainty of controller. All parameters coupled with the faulty measurement are replaced by its approximation. After the reconfiguration the pre-specified control performance can be recovered. FDI integrated FTC based on backstepping technique is implemented successfully on the electro-hydraulic testbed. The on-line robust FDI and controller reconfiguration can be achieved. The tracking performance of the controlled system is guaranteed and the considered faults can be tolerated. But the problem of theoretical robustness analysis for the time delay caused by the fault diagnosis is still open.


"Over the past twenty years, an abundance of art forms have emerged that use aesthetics to affect social dynamics. These works are often produced by collectives or come out of a community context; they emphasize participation, dialogue, and action, and appear in situations ranging from theater to activism to urban planning to visual art to health care. Engaged with the texture of living, these art works often blur the line between art and life. This book offers the first global portrait of a complex and exciting mode of cultural production — one that has virtually redefined contemporary art practice. Living as Form grew out of a major exhibition at Creative Time in New York City. Like the exhibition, the book is a landmark survey of more than 100 projects selected by a thirty-person curatorial advisory team; each project is documented by a selection of color images. The artists include the Danish collective Superflex, who empower communities to challenge corporate interest; Turner Prize nominee Jeremy Deller, creator of socially and politically charged performance works; Women on Waves, who provide abortion services and information to women in regions where the procedure is illegal; and Santiago Cirugeda, an architect who builds temporary structures to solve housing problems" -- p.

Updated to include the 196 new kanji approved by the Japanese government in 2010 as "general-use" kanji, the sixth edition of this popular text aims to provide the student of Japanese with a simple method for correlating the writing and the meaning of Japanese characters in such a way as to make them both easy to remember. It is intended not only for the beginner, but also for the more advanced student looking for some relief from the constant frustration of forgetting how to write the kanji, or for a way to systematise what he or she already knows. The author begins with writing the kanji because-contrary to first impressions-it is in fact simpler than learning how to the pronounce them. By ordering the kanji according to their component parts or "primitive elements," and then assigning each of these parts a distinct meaning with its own distinct image, the student is led to harness the powers of "imaginative memory" to learn the various combinations that make up the kanji. In addition, each kanji is given its own key word to represent the meaning, or one of the principal meanings, of that character. These key words provide the setting for a particular kanji's "story," whose protagonists are the primitive elements. In this way, one is able to complete in a few short months a task that would otherwise take years. Armed with the same skills as Chinese or Korean students, who know the meaning and writing of the kanji but not their Japanese pronunciations, one is then in a much better position to learn the readings (which are treated in a separate volume). has helped tens of thousands of students advance towards literacy at their own pace, and to acquire a facility that traditional methods have long since given up on as all but impossible for those not raised with the kanji from childhood.


Vietnam–China relations could be captured in the Chinese expression '同床异梦', 'same bed, different dreams'. Analysing Vietnam–China's asymmetric relationship, cultural and political similarities, divergences in global ambition and the involvement of foreign powers, this study shows how the relationship is increasingly interdependent but is equally fragile. One possible cause is the low level of trust on both sides, evidenced by repeated calls to 'consolidate political trust' or 'enhance mutual trust' in their high-level bilateral dialogues.


Corporate law is consumed with a debate over shareholder democracy. The conventional wisdom counsels that shareholders should have more voice in corporate governance, in order to reduce agency costs and provide democratic legitimacy. A second set of theorists, described as "board primacists," advocates against greater shareholder democracy and in favor of increased board discretion. These theorists argue that shareholders need to delegate their authority in order to provide the board with the proper authority to manage the enterprise and avoid short-term decision making. In the last few years, the classical economic underpinnings of corporate law have been destabilized by a growing recognition that shareholders are not a homogeneous group of wealth maximizers. This recognition has, among other things, undercut the arguments made in support of the typical corporate structure where shareholders alone possess the right to vote in corporate elections. Board primacy seems well-positioned to retheorize corporate law to adapt to this new reality. In their analyses of the issue, however, board primacy theorists have conflated two very different aspects of group decision processes: the responsiveness of the governance system and the composition of the electorate. This confusion ends up putting many board primacy theorists in the curious position of moving away from the public choice emphasis on preference aggregation toward a more civic republican model of less responsive, more deliberative decision making. By restricting the franchise, board primacists have detached their governance structures from the underlying desires of their constituents without substituting anything in their place. We argue, however, that the breakdown of this particular distinction between shareholders and other constituents could mean that we should investigate treating other constituents more like shareholders, rather than the other way around.


New media have markedly enhanced individuals' capacity to produce and disseminate original knowledge; however, the literature has not extensively examined the broad effects of such decentralized production processes. The current study thus focuses on a unique context — the stock market — in which it is possible to test the aggregate impact of blog-based information production. Using data on 150 top financial bloggers and stock returns from the S&P 500, this study supports the hypothesis that financial blogging activity diminishes harmful information asymmetries between key market investors. This study thus adds to the "media effects" literature, highlights the societal relevance of bloggers, and shows how economic concepts and financial market settings can be employed for powerfully testing communication theories.


This paper estimates the impact of climate change on the prevalence of criminal activity in the United States. The analysis is based on a 30-year panel of monthly crime and weather data for 2997 US counties. I identify the effect of weather on monthly crime by using a semi-parametric bin estimator and controlling for state-by-month and county-by-year fixed effects. The results show that temperature has a strong positive effect on criminal behavior, with little evidence of lagged impacts. Between 2010 and 2099, climate change will cause an additional 22,000 murders, 180,000 cases of rape, 1.2 million aggravated assaults, 2.3 million simple assaults, 260,000 robberies, 1.3 million burglaries, 2.2 million cases of larceny, and 580,000 cases of vehicle theft in the United States.


Previous commentators on the Rehnquist Court's history, seeking an overarching explanation for the Court's cases, have focused their attention primarily on a revitalized "federalism," an agenda-driven "conservatism," and a constitutionally fixated "judicial supremacy." While each of these themes is undoubtedly present in the Court's later jurisprudence, this Article argues that one cannot understand the Rehnquist Court's complicated intellectual matrix without taking account of its profound hostility towards the institution of litigation and its concomitant skepticism as to ability of litigation to function as a mechanism for organizing social relations and collectively administering justice. The Article takes a pointillist approach, commenting on a large swath of the Court's caseload and allowing a broader picture to gradually emerge from observations about seemingly discrete areas of law. It first unpacks the contours of the Rehnquist Court's hostility toward litigation, focusing attention on a number of areas where the Court has acted aggressively and explicitly to limit the scope or availability of litigation, including remedies and rights of action, qualified immunity and attorney's fees, the enforceability of mandatory arbitration agreements, and limitations on the permissible scope of punitive damage awards. The Article then moves from the explicit to the implicit, examining well-rehearsed areas of the Court's jurisprudence (such as its federalism cases and the 2000 Presidential election controversy) in an effort to identify the subtler effects of the Court's reflexive hostility to litigation on its constitutional docket. Finally, the Article pulls back from the cases to interrogate the sources of the Court's hostility to litigation, exploring not only the reasons for that hostility but also its curious coexistence with the Court's concurrent commitment to an aggressive form of judicial supremacy, particularly in the constitutional arena.


In this paper we compare the distribution of PPs introducing external arguments in nominalizations with PPs introducing external arguments in the verbal domain. We show that several mismatches exist between the behavior of PPs in nominalizations and PPs in the verbal domain. This leads us to suggest that while PPs in the verbal domain are licensed by functional structure alone, within the nominal domain, PPs can also be licensed via an interplay of the encyclopaedic meaning of the root involved and the properties of the preposition itself. This second mechanism kicks in in the absence of functional structure.


In this well-researched and fascinating book, noted journalist Thomas de Waal-author of the highly acclaimed Black Garden-makes the case that while the Caucasus is often treated as a sub-plot in the history of Russia, or as a mere gateway to Asia, the five-day war in Georgia, which flared into a major international crisis in 2008, proves that this is still a combustible region, whose inner dynamics and history deserve a much more complex appreciation from the wider world. In The Caucasus, de Waal provides this richer, deeper, and much-needed appreciation, one that reveals that the South Caucasus-Armenia, Azerbaijan, and Georgia, and their many smaller regions, enclaves, and breakaway entities-is a fascinating and distinct world unto itself. Providing both historical background and an insightful analysis of the period after 1991, de Waal sheds light on how the region has been scarred by the tumultuous scramble for independence and the three major conflicts that broke out with the end of the Soviet Union-Nagorny Karabakh, Abkhazia, and South Ossetia. The book examines the region as a major energy producer and exporter; offers a compelling account of the Rose Revolution in Georgia, the rise of Mikheil Saakashvili, and the August 2008 war; and considers the failure of the South Caucasus, thus far, to become a single viable region. In addition, the book features a dozen or so "boxes" which provide brief snapshots of such fascinating side topics as the Kurds, Turkish-Armenian rapprochement, the promotion of the region as the "Soviet Florida," and the most famous of all Georgians, Stalin. The Caucasus delivers a vibrantly written and timely account of this turbulent region, one that will prove indispensable for all concerned with world politics. It is, as well, a stimulating read for armchair travellers and for anyone curious about far-flung corners of the world.


We give an analytical and geometrical treatment of what it means to separate a Gaussian kernel along arbitrary axes in R, and we present a separation scheme that allows to efficiently implement anisotropic Gaussian convolution filters in arbitrary dimension. Based on our previous analysis we show that this scheme is optimal with regard to the number of memory accesses and interpolation operations needed. Our method relies on non-orthogonal convolution axes and works completely in image space. Thus, it avoids the need for an FFT-subroutine. Depending on the accuracy and speed requirements, different interpolation schemes and methods to implement the one-dimensional Gaussian (FIR, IIR) can be integrated. The algorithm is also feasible for hardware that does not contain a floating-point unit. Special emphasis is laid on analyzing the performance and accuracy of our method. In particular, we show that without any special optimization of the source code, our method can perform anisotropic Gaussian filtering faster than methods relying on the Fast Fourier Transform.

"Obesity is an important health issue, having risen to epidemic proportions in the U.S. Use of conjugated linoleic acid (CLA), positional and geometric isomers of linoleic acid, has received recent attention due to its potential health benefits including the reduction of fat mass in animals. However, the effectiveness and safety of CLA consumption in humans remains unclear. Our group previously reported that trans-10, cis-12 CLA impaired the conversion of preadipocytes into lipid-filled adipocytes (e.g., differentiation) and caused adipocyte delipidation that involved inflammatory cytokines in a human cell model. However, the isomer-specific mechanism for these events was unknown. Thus, this research examined mechanisms by which trans-10, cis-12 CLA induced adipocyte delipidation, inflammation, and insulin resistance in primary cultures of human adipocytes. Delipidation of adipocytes by trans-10, cis-12 CLA was accompanied by increased lipolysis and changes in the morphology of lipid droplets and the expression and localization of proteins regulating lipid droplet metabolism. This process involved the translational control of adipose differentiated related protein (ADRP) through activation of mTOR/p70S6K/S6 signaling and transcriptional control of perilipin A. Prior to these morphological changes, it was shown that trans-10, cis-12 CLA promoted nuclear factor κB (NFκB) and mitogen activated protein kinase (MAPK) activation and subsequent induction of interleukin (IL)-6 which were, at least in part, responsible for trans-10, cis-12 CLA-mediated suppression of peroxisome proliferator activated receptor gamma (PPAR)γ target gene expression and insulin sensitivity in human adipocytes. The essential role of NFκB on CLA-induced inflammation was confirmed by using RNA interference. Further studies were conducted examining the localization and characterization of the inflammatory response, including the type of cells involved, using lipopolysaccharide (LPS) as the inflammatory agent. It was demonstrated that LPS-induced, NFκB-dependent proinflammatory cytokine expression was predominantly from preadipocytes, which led to, at least in part, the suppression of PPAR activity and adipogenic gene expression and insulin sensitivity. Collectively, these data support the emerging concept that adipose tissue is a dynamic endocrine organ with the capacity to generate inflammatory signals that impact glucose and lipid metabolism. Furthermore, human preadipocytes have the capacity to generate these inflammatory signals induced by trans-10, cis-12 CLA and LPS, subsequently causing insulin resistance in neighboring adipocytes. These studies also revealed that NFκB- and MAPK-signaling mediate inflammation and insulin resistance induced by CLA and LPS. Thus, although the trans-10, cis-12 isomer of CLA may decrease the size and lipid content of human adipocytes, it may also cause insulin resistance, which is a hallmark of type 2 diabetes.

The linearized augmented plane wave (LAPW) method within the generalized gradient approximation (GGA) based on the density functional theory (DFT) is used to investigate the properties of fluorite structure actinide oxides such as AmO2 and PuO2. This work presents the study of the behavior of 5f sates and the fully relativistic spin-orbit coupling of the actinide compounds. The value of the Fermi energy for the AmO2 and PuO2 materials is 0.80561 and 0.78551 eV, respectively. The spin dependent structures show that the energy crosses the Fermi level which shows the both materials are metallic in nature. The crystal field splitting shows the energy gap for eg and t2g states. The value of crystal field splitting is 3.2 and 4.6 eV for AmO2 and PuO2, respectively.


As a surge in pirate attacks in the seas around the Horn of Africa threatens to seriously damage international trade, the nations of the world have refused to enforce international law against these criminals. The dozens of nations patrolling the Gulf of Aden have ample legal authority to detain and prosecute pirates. Yet the United States and other navies have, as a matter of policy, been releasing apprehended pirates because of the difficulty of detaining or successfully prosecuting them. These fears are not unwarranted. As this Essay shows, while on the one hand international law requires all nations to fight pirates, a variety of other international legal rules - ranging from the Geneva Conventions to refugee law to the Law of the Sea Treaty - are in tension with this goal. These tensions are daunting enough to keep nations from even trying. The legal issues that prevent states from effectively dealing with pirates are precisely the same as those that have plagued responses to international terrorism. The War on Piracy and the War on Terror both raise questions about the legal status of conflicts between traditional states and diffuse multinational networks. Pirates, like terrorists, fall in the gray zone between military combatants and civilians. But the similarities between the legal problems of piracy in Somalia and those of the battle against international terrorism do not end there. Lack of clarity about pirates' prisoner of war status, the use of prolonged detention, rendition to countries with poor human rights records, claims of abuse by the detainees, accidental killings of innocent civilians, the difficulty of proving cases arising from the field of active military operations in civilian court, and the legality of targeted killings of suspected wrongdoers are just a few of the issues that have plagued both legal efforts against international terrorists and against piracy in just the first few months of the current Somali campaign. The legal response to terrorism has been among the most contentious public issues in recent years. It is widely asserted that trying foreign terrorists in civilian courts is a workable response. However, the failure of this same strategy in the case of piracy - indeed, the refusal of the very nations that promote such an approach for terrorism to even attempt it with piracy - suggests that the civilian approach to terrorism will be extraordinarily challenging. For a variety of reasons, piracy would be far easier to deal with than terrorism. Thus, the legal impediments to dealing with piracy serve as an ideal case study for the future of terrorism prosecutions.
