Background Systemic lupus erythematosus (SLE) is a systemic autoimmune disease often characterised by the development of glomerulonephritis.1 There is a growing interest in the use of mycophenolate mofetil (MMF) as induction therapy and maintenance therapy for lupus nephritis.2, 3 Objectives This study aimed to evaluate the therapeutic outcome of MMF in lupus nephritis from real-world clinical practice, and identify the predictors for failure of remission after MMF treatment. Methods Korean patients with pathologically proven lupus nephritis class III, IV, and V were recruited from rheumatology clinic in Severance Hospital, Yonsei University College of Medicine between Nov 2011 and Aug 2017 Patients who treated with MMF for at least 3 months were included in the analysis. The probability of remission after MMF therapy, and the difference between patients who achieved remission or failed to achieve remission were analysed using Kaplan-Meier analysis and Cox proportional hazards model. Results Of 153 patients with lupus nephritis, 116 patients were included in this study. Seventy two patients continued MMF until the last follow-up. The mean age of patients was 34.2 years, and the median duration of SLE was 5.7 months. Anti-dsDNA antibody was positive in 82.8% of patients, and 9.5% of patients showed a histological class with pure V pathology. Mean protein/creatinine ratio in spot urine was 4.6, and active urinary sediment was found in 82.8% of patients. During median follow-up period of 5 years, 80% of patients achieved clinical remission of lupus nephritis. Median time to remission was 4.2 months (IQR 0.9–9.1). Risk factors for failure of remission were nephrotic-range proteinuria and seronegativity of anti-dsDNA antibodies. Conclusions This study shows the real-world data on MMF treatment in patients with lupus nephritis. Patients with risk factors for failure to remission may require more intensive treatment and management. References [1] Yu F, Haas M, Glassock R, Zhao MH.

The article provides an α-cut-based method that solves linear fractional programming problems with fuzzy variables and unrestricted parameters. The parameters and variables are considered as asymmetric triangular fuzzy numbers, which is a generalization of the symmetric case. The problem is solved by using α-cut of fuzzy numbers wherein the α- and r-cut are applied to the objective function and constraints, respectively. This reduces the problem into an equivalent biobjective model which leads to the upper and lower bounds of the given problem. Afterwards, the membership functions corresponding to various values of r∈(0,1] are obtained using the optimal values of the biobjective model. The proposed method is illustrated by taking an example from the literature to highlight the fallacy of an existing approach. Finally, a fuzzy linear fractional transportation problem is modelled and solved using the aforementioned technique.


Acoustic waves and pulses propagating from the solar photosphere upwards may quickly develop into shocks due to the rapid decrease of atmospheric density. However, if they propagate along a magnetic flux tube, then the non-linear steepening may be balanced by tube dispersion effects. This may result in the formation of a sausage soliton. The aim of this Letter is to report observational evidence of a sausage soliton in the solar chromosphere. A time series of the Ca ii H line obtained at the solar limb with the Solar Optical Telescope (SOT) on board Hinode is analysed. Observations show an intensity blob, which propagates from 500 to 1700 km above the solar surface with a mean apparent speed of 35 km s−1. The speed is much higher than the expected local sound speed, therefore the blob cannot be a simple pressure pulse. The blob speed, length-to-width ratio and relative intensity correspond to a slow sausage soliton propagating along a magnetic tube. The blob width increases with height corresponding to the magnetic tube expansion in the stratified atmosphere. Propagation of the intensity blob may be the first observational evidence of a slow sausage soliton in the solar atmosphere.

The model cross-coupling of EtBr with EtMgCl mediated by Ni(pi-allyl)(2) proceeds by a catalytic cycle commencing with transmetalation establishing a novel Mg-allyl interaction, followed by Mg-assisted oxidative addition (the rate-determining step), followed by reductive elimination having much lower barrier than 2 competing beta-hydride elimination pathways, and completed by departure of MgBrCl.


Cambodia is sadly known for the terrible crimes committed during the Khmer Rouge regime between 1975 and 1979. The history that followed this period was marked by a multifaceted conflict that lasted for nearly 20 more years. In this particularly complex context, the process of disarmament, demobilization, and reintegration (DDR) was essential to guarantee the transition of this devastated country towards peace and stability. The objective of this article is to present the initiatives of DDR in Cambodia between 1992 and 2002, the challenges and difficulties brought by their implementation, and the causes of their failure. The article also outlines the government's policy that led to the dismantlement of the Khmer Rouge in the 1990s, as well as the arms control programs implemented between 2000 and 2008. These two measures contributed successfully to pacify the country, to improve security conditions and to mitigate the failure of DDR.


In lieu of real patients, healthcare educators frequently use simulated patients. Simulated patients can be realized in physical form, such as mannequins and trained human actors, or virtual form, such as via computer graphics presented on two-dimensional screens or head-mounted displays. Each of these alone has its strengths and weaknesses. I introduce a new class of physical-virtual patient (PVP) simulators that combine strengths of both forms by combining the flexibility and richness of virtual patients with tangible characteristics of a human-shaped physical form that can also exhibit a range of multi-sensory cues, including visual cues (e.g., capillary refill and facial expressions), auditory cues (e.g., verbal responses and heart sounds), and tactile cues (e.g., localized temperature and pulse). This novel combination of integrated capabilities can improve patient simulation outcomes. In my Ph.D. work I focus on three primary areas of related research. First, I describe the realization of the technology for PVPs and results from two user-studies to evaluate the importance of dynamic visuals and human-shaped physical form in terms of perception, behavior, cognition, emotions, and learning. Second, I present a general method to numerically evaluate the compatibility of any simulator-scenario pair in terms of importance and fidelity of cues. This method has the potential to make logistical, economic, and educational impacts on the choices of utilizing existing simulators. Finally, I describe a method for increasing human perception of simulated humans by exposing participants to the simulated human taking part in a short, engaging conversation prior to the simulation.


Damage degree of soybean pod borer(Percentage of Damaged Seeds)is influenced by quantitative factors(over-winter cardinal number,meteorological condition etc.)and qualitative factors(variety,control measures etc.).According to eleven factors related to damage degree,such as average shelling percentage of last year,soybean varieties,control situation,survival rate of overwintering larvae and so on,this paper built model by taking percentage of damaged seeds as reference variables,and then predicted occurrence probability of various damage degree on soybean pod borer by using quantification theory I.In the return analysis of level-3 model for 73 samples,63 samples were right and the return rate was 86.30%.Eight samples,accounting for 10.96% of the total behaved grade 1 forecast error.Results suggest the prediction model has practical significance for its higher precision of return analysis.


This paper collects the SoC (State-of-Charge) changes of electric vehicles and analyzes the battery consumption behavior. For multiple SoC streams generated on the same road, a Hadoop Pig script filters essential information fields out of the vast amount of SoC records, while its user-defined function adds the distance and the time taken from the start point. Next, neural networks are built to trace the SoC dynamics according to both spatial and temporal aspects of SoC records using the R statistics package. A time-combined model reduces the fitting error by 50 %, compared with the distance-only model. The ongoing project keeps accumulating SoC streams and our model will investigate the effect of other parameters and correlate different streams. An accurate model for major roads taken by most trips, will lead to a more efficient estimation of battery consumption for any point-to-point routes.


This paper presents a new adaptive multi-grid method for analyses on damage and failure in concrete column under cyclic loading. Self-adaptation of the method can carry out automatically coupling analysis on the process of evolving damage to structural failure with dynamic grid-change due to damage, without user intervention in the computation. The theory of multi-grid FEM coupled evolving damage is developed on the basis of the improved variational principle to consider damage evolution, in which the elements in each sub-domain with different grid sizes are under the different state of damage. Then the multi-grid FEM method is provided with the theory and a 3D adaptive mesh refinement procedure. As a case study of the method, the process of evolving damage to failure of a concrete column under cyclic loading is simulated by using the developed method, and the simulated results fit well with the experimental data. The results show that, the developed method is reliable in simulation on evolving damage and failure in concrete column under dynamic seismic loading with lower cost and sufficient precision.


Since two decades, wavelet packet decompositions have been shown effective as a generic approach to feature extraction from time series and images for the prediction of a target variable. Redundancies exist between the wavelet coefficients and between the energy features that are derived from the wavelet coefficients. We assess these redundancies in wavelet packet decompositions by means of the Markov blanket filtering theory. We introduce the concept of joint Markov blankets. It is shown that joint Markov blankets are a natural extension of Markov blankets, which are defined for single features, to a set of features. We show that these joint Markov blankets exist in feature sets consisting of the wavelet coefficients. Furthermore, we prove that wavelet energy features from the highest frequency resolution level form a joint Markov blanket for all other wavelet energy features. The joint Markov blanket theory indicates that one can expect an increase of classification accuracy with the increase of the frequency resolution level of the energy features.


. A method is described that uses the invariant mass and energy conservation laws in order to extract a detailed pattern of mass and energy flows from the instru mentation of a process plant. The basic feature of the method is that it is applicable to a large range of plant operational situations, such as those initiated by unfore seen failures, failures with dynamic symptoms, multiple failures, and failures during sequential operations. The authors' intentions with this interim progress report are to describe the basic ideas behind the method, as well as to discuss some of its implications for man-computer cooperation in process plant diagnosis.

In spite of the rise in the global adoption of public private partnerships, developing countries have failed to attract private investments in equally measure as their developed partners. This has impacted on infrastructural financing in developing countries. The current study sought to establish how market risks influence the performance of public private partnership renewable energy projects. The study adopted a pragmatic paradigm and employed a mixed methods approach, correlational and descriptive survey design. Quantitative data was collected by use of a self-administered questionnaire and while an interview guide was used to collect qualitative data after piloting and reliability established. A sample size of 263 respondents was drawn from a target population of 769 using the Yamane formula. For descriptive statistics the study used the mean and standard deviation. For inferential statistics the study used Pearson's Product Moment Correlation (r) and Multiple Regression while the F-tests were used in hypothesis testing. The study established a significant influence of market risks on the performance of public private partnerships renewable energy projects F (1,204) =104.689, P=0.000  ˂ 0.05. H0 was consequently rejected. Based on this finding the study recommends hedging measures to promote public private partnerships. © 2020 by the authors. Licensee SSBFNET, Istanbul, Turkey.

Abstract In this article, we introduce the notion of "metrically differentiable" for set-valued functions. By using this notion, it is shown that each Lipschitz set-valued function is differentiable almost everywhere. Its relationship to the differentiation in the sense of Hukuhara and its generalizations are also discussed.

A test for the diagnosis of pheochromocytoma associated with persistent hypertension was published inThe Journalin 1947. 1 Since these neoplasms are more often associated with persistent elevation in blood pressure than with the more dramatic paroxysmal hypertension, and since the clinical picture of these cases is often indistinguishable from that of essential and malignant hypertension, pharmacologic means have to be used to differentiate these diseases. The adrenergic blocking action of the benzodioxans was used to demonstrate the presence of circulating epinephrine. Whereas pheochromocytqmas responded with a drop of systolic and diastolic blood pressure, hypertension of other causation showed no change or a rise of blood pressure after intravenous administration of benzodioxan. Recently the normal adrenal medulla 2 and pheochromocytomas 3 have been shown to contain not only epinephrine but also varying amounts of the corresponding primary amine, arterenol (nor-epinephrine). Arterenol produces in man hemodynamic changes quite different from


A new method for testing brake lining materials in the laboratory is described. This method is essentially isothermal by nature, thus avoiding the usual problems associated with differences between the heat-transfer characteristics of brake assemblies in road vehicles and those of laboratory test rigs. As an example of application of the method, friction-time-temperature curves of five different brake lining materials are presented and discussed in terms of time- and temperature-depending transformations in the composition of the lining materials. The quality of the materials is described by the following properties: temperature range in which glazing effects occur; temperature range in which carbonization effects occur; steady-state value of the coefficient of friction; wear (decrease in thickness) of the lining; and sensitivity of the lining material to moisture.


Manasseh's son Amon has what appears to be an Egyptian name. This article argues that Manasseh, who fought alongside Ashurbanipal on his first campaign in Egypt in 667 BCE, named the son born to him during Ashurbanipal's second campaign in 663 BCE as a flattering commemoration of his overlord's capture of the rebel capital Thebes in that year.


Abstract Context The potential anti-inflammatory bioactivities of β-hydroxyisovalerylshikonin (β-HIVS) remain largely unknown. Objective This study investigated the anti-inflammatory effects and underlying mechanisms of β-HIVS. Materials and methods RAW 264.7 cells stimulated with LPS (100 ng/mL) for 24 h were treated with the non-cytotoxic doses of β-HIVS (0.5 or 1 μM, determined by MTT and Trypan blue staining), qRT-PCR and FCM assay were used to examine macrophage polarization transitions. Western blotting was used to evaluate the activation of the AMPK/Nrf2 pathway. In vivo, C57BL/6 mice were randomly divided into vehicle control, LPS (10 mg/kg), and β-HIVS (2.5 mg/kg) combined with LPS (10 mg/kg) groups, blood samples, BALF, and lung tissues of mice were subjected to ELISA, qRT-PCR, FCM, and H&E staining. Results β-HIVS (1 μM) inhibited LPS-induced expression of M1 macrophage markers (TNF-α: 0.29-fold, IL-1β: 0.32-fold), promoted the expression of M2 macrophage markers (CD206: 3.14-fold, Arginase-1: 3.98-fold) in RAW 264.7 cells; mechanistic studies showed that β-HIVS increased the expression of nuclear Nrf2 (2.04-fold) and p-AMPK (3.65-fold) compared with LPS group (p < 0.05). In vivo, β-HIVS decreased the levels of pro-inflammatory cytokines (TNF-α: 1130.41 vs. 334.88 pg/mL, IL-1β: 601.89 vs. 258.21 pg/mL in serum; TNF-α: 893.07 vs. 418.21 pg/mL, IL-1β: 475.22 vs. 298.54 pg/mL in BALF), decreased the proportion of M1 macrophages (77.83 vs. 68.53%) and increased the proportion of M2 macrophages (13.55 vs. 19.56%) in BALF, and reduced lung tissue damage and septic mice survival (p < 0.05). Conclusions These results indicate that β-HIVS may be a new potential anti-inflammatory agent.

Based on analysis with ESDA-GIS framework, by using statistical data of 1346 small cities and towns in Jiangsu province in 2002, their spatial structure was studied. We, at first, finished summary factor analysis from database, and drew the two principal components: economic factor and scale factor. By comparison, we found that the frequency distribution of the two factors was skewed and the skewed degree of scale factor was higher than that of economic factor. But there is no positive correlation as scale-benefit between the two factors. In this paper, exploratory spatial structure of the small cities and towns was analyzed. With the density map, we found their spatial distribution is imbalanced, whose density would descend gradually from Yangtze River zone and Taihu Lake area in the southeast to the west and the north, which showed a belt and circle structure. Based on the analysis with global SAMs and local SAMs, we came to some conclusions. The spatial distribution of economic factor of the small cities and towns showed positive autocorrelation and spatial cluster, but the autocorrelation of scale factor is very weak. Finally, after classifying the local SAMs coefficients of small cities and towns according to administrative units of country, we analyzed economic significance with anisotroptric variogram and improved the classified result. We found the spatial cluster of the economic development of the small cities and towns in Jiangsu province: three districts, one belt, and one part, i.e., the middle part of the northern Jiangsu area, the middle part of Jiangsu province and Nanjing-Zhenjiang area, Suzhou-Wuxi-Changzhou area, and the northern part of Jiangsu border belt, and district around Suining. The corresponding economic development types are diffusing development type, polarizing development type, clustering development type, transitional development type, and continual impoverished type.


Graph pattern mining (GPM) is a class of algorithms widely used in many real-world applications in bio-medicine, e-commerce, security, social sciences, etc. GPM is a computationally intensive problem with an enormous amount of coarse-grain parallelism and therefore, attractive for hardware acceleration. Unfortunately, existing GPM accelerators have not used the best known algorithms and optimizations, and thus offer questionable benefits over software implementations.We present FlexMiner, a software/hardware co-designed GPM accelerator that improves the efficiency without compromising the generality or productivity of state-of-the-art software GPM frameworks. FlexMiner exploits massive amount of coarse-grain parallelism in GPM by deploying a large number of specialized processing elements. For efficient searches, the FlexMiner hardware accepts pattern-specific execution plans, which are generated automatically by the FlexMiner compiler from the given pattern(s). To avoid repetitive computation on neighborhood connectivity, we provide dedicated on-chip storage to memoize reusable connectivity information in a connectivity map (c-map ) which is implemented with low-cost yet high-throughput hardware. The on-chip memories in FlexMiner are managed dynamically using heuristics derived by the compiler, and thus are fully utilized. We have evaluated FlexMiner with 4 GPM applications on a wide range of real-world graphs. Our cycle-accurate simulation shows that FlexMiner with 64 PEs achieves 10.6× speedup on average over the state-of-the-art software system executing 20 threads on a 10-core Intel CPU.


Abstract In his The Salvation and The Remarks and Admonitions, Avicenna presents a well-known argument for the existence of God as a necessary being by itself. I will suggest, first of all, that the two pivotal notions employed in the argument, namely those of a necessary being by itself and a contingent being by itself, can be construed in different ways, leading to different versions of Avicenna's argument. I then turn to a specific version of the argument which seeks to show that there is at least one independently existing entity. This version constitutes the core of other versions of Avicenna's argument. Next, I shall explore how one might move from the existence of an independently existing entity to that of a necessary being by itself (variously construed). Finally, I will argue that the Avicennian argument for an independently existing entity suffers from a severe problem in that it fails to take account of the possibility of many-to-one causal relation.

High perinatal mortality has been reported in association with the finding of absent end‐diastolic flow velocities in the umbilical artery. The fetus is known to centralize its circulation during hypoxemia and abnormal venous blood flow velocities have been reported in cases of heart failure and imminent asphyxia. The aim of this study was to evaluate blood flow velocities recorded with Doppler ultrasound in the umbilical vein, inferior vena cava and middle cerebral artery as predictors of survival in 17 fetuses with absent or reversed end‐diastolic flow in the umbilical artery.


Aqueous leaf extracts of two naturally growing plants in Nigeria viz: Vernonia amygdalina and Ocimum gratissimum were admixed with maize grains infested with maize weevil, Sitophilus zeamais Motsch. in the laboratory at 30±30C and 75±2% relative humidity. The plant extracts showed efficiency against the test insect with respect to adult mortality, larval and progeny emergence and percentage grain damage. Adult mortality was highest (88.9%) in maize grains treated with 3% (v/w) of the leaf extracts 3 days post treatment. It was observed that leaf extracts of V. amygdalina and O. gratissimum applied at 3% per 30 g maize grains caused significantly higher (P<0.05) adult mortality than the 1% rate of treatment during storage. There was significant difference in the rates of treatment of V. amygdalina causing grain damage compared to the control. The results suggest the ability of using these plant extracts for maize protection against maize weevils with V. amygdalina showing greater potential.

A full-term newborn was examined after lower segmental cesarean section. There were no antenatal complications. Clinically, there was overlapping of upper lids over lower eyelids when the baby was crying, but reduced when the baby was asleep. The upper eyelids became normal within 2 days of delivery without any treatment. We report one such case.


The nanoworld contains a variety of molecules that constitute functional matter, living organisms, or other small objects. To use information on such real objects effectively, it is necessary to develop nanoscale processors that can deal with the information directly on the nanoscale. In this paper, we present a method for implementing an automaton on the nanoscale using photonics and DNA. The conformation of DNA is utilized to represent the state of the automaton, and it is changed in accordance with the optical input to execute a state transition. We designed DNA reaction schemes to implement any two-state and two-symbol transition diagrams. Different responses to a set of input symbols (optical signals) are obtained in the individual schemes. Experimental results demonstrate that expected conformations of DNA were produced by the optical input.

To the Editor. —The recent article1and the accompanying Editorial2inJAMAare more about the interaction between the two major principles of deontological ethics (autonomy and beneficence) than about truth telling. Taken together they form an excellent primer on the proper interpretation and function of autonomy and beneficence in the clinical setting. Some clinicians and ethicists dwell too long on the potential conflict between patients' autonomy and physicians' obligations to promote patients' best interests. This may be a reaction to past abuses in clinical decision making, grounded in parentalism (paternalism), in which patients' values were rarely accounted for or completely ignored. Physicians must serve their patients, but they are not servants of their patients. Most patients do not want their physicians to be mere "technological waiters," proffering menus of high-tech items from which they choose their own treatments. Clinical medicine involves two parties with differing perspectives, values,


This paper aims to construct a hedonic price model to stimate the price-satisfaction relationship in the acquisition of new low-price vehicles. The i nitial hypothesis is that the prices of vehicles ar e estimated in function of the presence or not of sev eral attributes. The technique of multiple linear regression analysis was used to determine the main attr butes that contribute to the final price of the vehicle. The data used in the study concern fiv e automotive industries in Brazil. Results of data collected from five assemblage companies in th e country indicate that the most important attributes in the price composition are air bag, ai r conditioning, hydraulic wheeling and sedan trunk, while the least important ones are rear-glas s cleaner, rear glass defogger, heater and metallic painting.

This paper presents a Finite Element Analysis (FEA) of modal energy exchange and harvesting in a simple portal frame structure. We consider both horizontal and vertical support excitations resonant first with the first mode (sway mode) and latter with the second mode (the first symmetrical mode). As 2:1 internal resonance is present between these two modes, the phenomena of mode saturation and energy exchange (modal coupling) may occur. Thus, energy pumped into the system through one of the modes, is partially transferred to the other mode, not directly excited. An evaluation of the energy available for harvesting in each of the considered mode is computed.


Abstract The EPR (European Pressurised Water Reactor) developed by AREVA is a new nuclear reactor designed to achieve greater output (1600 MW) and longer plant life (60 years) than conventional nuclear reactors. The first one is currently under construction in Finland at Olkiluoto. For this new design, an integrated forging was applied for the nozzle shell, including an integral flange (Fig. 1).

Cyclic oligomers of engineering plastics such as polycarbonate and aromatic polyesters have been known for some time, being formed at very low levels during commercial manufacture. At GE Global Research, we have devised methods for high-yielding and selective preparation of such cyclic oligomers, that are amenable to commercial manufacture. The mixtures of cyclic oligomers have melting points significantly lower than individual ring sizes, and have very low viscosities in the melt. Ring-opening polymerization using appropriate initiators affords rapid reactions (2–6 min) without measurable exotherm, providing very high-molecular-weight polymers and without reaction byproducts. These materials have been scaled to commercial quantities, and have shown to be extremely useful for fabrication of glass and carbon fiber composites with high-fiber fractions. © 2008 Wiley Periodicals, Inc.

The nonlinear frequency shift of a low-frequency, coherent dust-acoustic wave in the presence of higher frequency dust-acoustic turbulence is investigated in the framework of weak turbulence theory. It is found that the frequency shift of the dust-acoustic wave in an unmagnetized dusty plasma is always positive irrespective of the propagation direction of the coherent wave. It is also found that turbulent waves propagating in the same direction as the coherent wave are shown to give rise to a much higher frequency shift than the opposite case. Finally, it is shown that the nonlinear frequency shift of a dust-acoustic wave is more pronounced than in the case of the customary ion-acoustic waves in fully ionized plasmas.


Cartilage tissue engineering is a promising therapy for articular cartilage lesions.But the problem how to quickly fix the constructed cartilage tissue in vitro to the natural tissue is still under research.This would influence the wide application of cartilage tissue engineering production in clinical practice.In this study,a layered articular cartilage tissue engineering scaffold was made by the freeze-dry method.The upmost layer is a pure collagen layer and the downmost layer is a collagen/hydroxyapatite(HA) composite layer.Between the two layers are the layers that the HA contents increased.This structure with the HA contents has the osteoconduction capacity,and makes it possible to achieve the fast fixation function of the engineered cartilage through the interaction between the bone and the HA contents in the scaffold once the scaffold implanted into the tissue.The fabrication method and the structure properties of the layered scaffold were discussed in this paper.The results showed that the pore size and porosity of the collagen layer could be controlled by the frozen temperature and the collagen solution concentration.The HA particle size and distribution of it would influence HA′s distribution in the collagen scaffold.SEM pictures showed that the fabricated layered collagen/HA composite scaffold was a 6cm cylinder with three different HA content containing layers.Each layer had a height about 2cm.The three layers formed a homogeneous unit without any separation between each layer.The layered scaffold could be a promising candidate for the cartilage tissue engineering.

Advance online publications or online first publications of academic journals,which generally refer to a digital edition of peer-reviewed articles before print publication,are an important part of achieving sustainable development of journals.Its benefits are quick and easy.Now,advance online publications have not received wide acceptance as same as print publication in China,so its development still faces many difficulties and challenges.


More than 90% of the world's population suffer from one or more oral conditions that affects their oral health related quality of life. Edentulism (partial or full) is a major public health problem especially in poorer settings where people have limited options to manage tooth pain, tooth decay or periodontal disease. Often the only treatment option available is tooth extraction resulting in early tooth loss. In other settings, for example, the Western Cape, cultural and traditional norms practiced over generations has resulted in some of the highest edentulism rates in the world.
Placement of a stainless steel crown (SSC) is the most commonly recommended restoration following endodontic treatment of primary molars,1 as it provides a good coronal seal, preventing microbial infiltration or restoration failure over time. However, dental aesthetics are compromised due to colour characteristics of the SSCs, which may influence child's and parent's acceptance, especially when compared to more aesthetic options such as composite resins (CRs).


Invasive plant species pose a threat to biodiversity worldwide. Ecological disturbances, such as those created by fallen trees, create conditions in which invasive plant species can establish and thrive. This study investigated whether treefall gaps have higher richness of invasive plant species than other areas within forests and potentially serve as a source for the spread of invasive species. A nine-hectare area of mature deciduous forest at the Smithsonian Environmental Research Center (SERC) near Edgewater, MD, was censused for invasive plant species during the summers of 2011 and 2012. The area was divided into 2m x 2m subplots, and the presence or absence of invasive plant species was recorded for each subplot. Gaps were defined as areas in which there was no canopy cover above 10m. The species richness of invasive plants in gap and non-gap areas was analyzed using ArcGIS. No significant association between invasive plant species richness and treefall gaps was found. However, there was a positive association between coarse woody debris cover and invasive plant species richness.


Transparent Er 3+/Yb3+ co-doped nano-FAP glass ceramics are prepared,and their near infrared luminescence properties are investigated.After heat-treatment,it is found through X-ray diffractions and transmissions electron microscopy measurements that the Ca 5(PO 4) 3 F crystals with mean size of 20 nm are precipitated in the glass matrix,and that rare earth ions are incorporated into FAP nano-crystals.Compared with the samples before heat-treatment,the Er 3+/Yb3 + co-doped glass ceramics give very strong 1.54 μm near-infrared luminescence under 808 nm and 980 nm laser diode excitations,whose full-width at half-maximum(FWHM) reaches to 75 nm.Moreover,the relationship between 1.54 μm near-infrared luminescence of glass ceramics and concentrations of Er 3 + and Yb 3 + is investigated.The highly efficient near-infrared luminescence properties indicate that Er3+/Yb3+ co-doped FAP glass ceramics is considered to be a promising laser and amplifier material.

The activity of single units in the inferior colliculus of the albino rat was recorded while clicks, tones, or noise bursts were presented with various interaural time and intensity differences. The range of time and intensity differences used approximated those which occur naturally in the rat. Overall firing rate, probability of firing, and initial latency were measured. For many cells, firing rate and probability of firing increased and latency decreased when the contralateral ear was stimulated earlier in time or more intensely than the ipsilateral ear. While plots of firing rate versus interaural time or intensity differences for these cells exhibited maxima and minima, the peaks were often outside the range of time and intensity differences naturally encountered. Many showed multiple peaks or broad plateaus extending over a wide range of time and intensity differences. For some cells, the location of the peaks was not consistent for the various kinds of stimuli used. When probability of a response a...


Objective To assess the value of ultrasonic techniques in monitoring the morphology and histology characteristics of aorta in atherosclerotic rabbits. Methods Forty male New Zealand rabbits were divided randomly into normal group and atherosclerosis (AS) group. The data were obtainded at the beginning, the 4th, 8th and 12th weekend of the experiment, which included the values of connected echo intensity in aortic intima-media (AIIc%), intima-media thickness (IMT), aortic sytolic diameter (Ds) and peak systolic velocity (Vp) in ascending aortic, and the values of TC, TG, HDL-C, LDL-C of plasma. Aortic specimens were obtainded at different stages and detected respectively by light and transmission electron microscopy and immunohistochemitry.

The proliferation of rabbit aortic smooth muscle cells (SMC) and the expression of protein were increased significantly in AS group. Conclusion Ultrasonic techniques provide a reliable method for monitoring the atherosclerosis progression. The proliferation of SMC and the formation of elastic fibers results in the increase of AIIc% in AS aorta.


Industry studies in recent years have raised awareness of the magnitude of asset renewal and replacement needs in the water industry, but little comparative work has been done on asset management. To help fill this gap, the Awwa Research Foundation sponsored the study summarized in this article. The full study forms a "casebook" of comparative asset management options. Eleven utilities of diverse sizes, asset ages, availability of automated information, and engagement in asset management worked with the project team to test and evaluate three levels of asset management planning: basic, high‐end, and strategic. The study results showed that even a basic asset management option has considerable value for a water utility. More advanced and strategic options require significant additional investment, but 80% of the utilities that participated in this project found the benefits to outweigh the costs and plan to implement programs that emulate these options.

Evaluating the various vacuum equipment options and installing a proper vacuum system are important. However, once in operation, performance shortcomings do occur for a variety of reasons. Evaluating the capabilities of the vacuum equipment vendor is essential. Does the vendor have proven experience with your type of application? Can the vendor adequately support your project with accurate and timely information both before and after an order? And, most importantly, is the vendor able to expediently service the vacuum equipment once it is in operation? These are all questions that must be part of the vendor selection process. This issue presents four case studies of performance problems and how a competent field service engineer solved and corrected the problem. A p p l y i n g Va c u u m Te c h n o l o g y


(Idiopathic thrombocytopenic purpura) Too often purple saturates your skin far too many places, playing a twisted game, connecting dots along the path of edges and elbows that left their memory on yours. Too often tears drain your eyes. Those war wounds from every kitchen you enter, some door closing, a child's ill manners, a moment misspent, a hand mislaid. Too often you wear long sleeves, high collars, pants instead of skirts, hoping to hide the ripe or fading colors from eyes that question and contendperhaps your own. Too often my lips can't quite measure your pain, can't relieve it, can't taste the salt in your tears or stop them from running your mascara into unending black rivers. Too often my words fail to find their target inside your heart, leaving them yet to release the ease of laughter you've long stored and masked with blushes and lipstick that cover it all. Audio.

BIOLOGICAL EVALUTION OF Yb-EDTMP AS RADIOPHARMACEUTICAL FOR BONE PAIN PALLIATION. Ideal radiopharmaceutical used as bone pain palliatives requires a moderate energy β emitter with a stable carrier molecule. Ytterbium-175 (T1/2 = 4.2 d, Eβ(max) = 0,480 MeV) has radionuclide properties suitable for palliative therapy of bone metastases. Ethylenediaminetetramethylene phosphonic acid (EDTMP) is known to form complexes with high stability. The present study was conducted to evaluate EDTMP complexed with Yb as radiopharmaceutical for bone imaging and potential agents for bone palliation which produced by PTNBR-BATAN Bandung. The Yb-EDTMP radiopharmaceutical was tested for the biodistribution and blood clearance. The bone uptake of Yb-EDTMP complexes are 12.68; 11.83; 10.00; and 8.20 (%ID) at 1, 3, 5 and 24 h post-injection. The radioactivity level in the stomach was 0.06 (%ID/g) up to 24 h post-injection, indicating that Yb-EDTMP remained stable in vivo. The blood clearance study exhibited that Yb-EDTMP had fast clearence profile from blood.This study showed that Yb-EDTMP is potential as radiopharmaceutical for bone pain palliation agents.


The purpose of this study iswas to examine consumer protection and control of products circulating in Mandailing Natal Regency in consuming goods or services, the government issued a policy of regulating consumer rights through laws as the implementation of a properous state. As consumers we must know what products an services can be consumed properly. Consumers cannot be separated from the rights and obligations of a producer. In this case the producer is the party that makes or produces the product. And until now, there are still many business actors who deliberately sell produts that are no longer fit for circulation. This study uses a qualitative research method with  a descriptive approach. Law Number 8 of 1999 concerning Consumer protection states that consumer rights in relation to consumer protection for the distribution of health products are the right to comfort, security and safety in obtaining or using these health products. Consumers of health products have the right to correct, clear anda honest information regarding the conditions and guarantees of goods and consumers also have the right to have their opinions heard on the of health products.

Internet of Things (IoT), an emerging technology, is becoming an essential part of today's world. Machine learning (ML) algorithms play an important role in various applications of IoT. For decades, the location information has been extremely useful for humans to navigate both in outdoor and indoor environments. Wi-Fi access point-based indoor positioning systems get more popularity, as it avoids extra calibration expenses. The fingerprinting technique is preferred in an indoor environment as it does not require a signal's Line of Sight (LoS). It consists of two phases: offline and online phase. In the offline phase, the Wi-Fi RSSI radio map of the site is stored in a database, and in the online phase, the object is localized using the offline database. To avoid the radio map construction which is expensive in terms of labor, time, and cost, machine learning techniques may be used. In this research work, we proposed a hybrid technique using Cuckoo Search-based Support Vector Machine (CS-SVM) for real-time position estimation. Cuckoo search is a nature-inspired optimization algorithm, which solves the problem of slow convergence rate and local minima of other similar algorithms. Wi-Fi RSSI fingerprint dataset of UCI repository having seven classes is used for simulation purposes. The dataset is preprocessed by min-max normalization to increase accuracy and reduce computational speed. The proposed model is simulated using MATLAB and evaluated in terms of accuracy, precision, and recall with K-nearest neighbor (KNN) and support vector machine (SVM). Moreover, the simulation results show that the proposed model achieves high accuracy of 99.87%.

Two dimensional magnetic recording (TDMR) technology aims at achieving recording densities as high as 10 Tb/in2 with the current interest in achieving >1 Tb/in2. In TDMR, the size of a bit is reduced to the order of the size of magnetic grains. The effects of this are two-fold: a) increased interference in cross-track as well as down-track directions and b) ultra high jitter noise due to irregular grain positions. Channel models that include the grain distributions on the medium give a more accurate jitter noise characteristics than the first order linear approximations of the jitter noise. Signal detection for 2D-ISI channels is well known to be NP-hard. JTED algorithm, proposed in [3], is proved to iteratively achieve maximum aposterior (MAP) performance. Partial response maximum likelihood (PRML) detection is a well known technique for reducing signal detection complexity by using a linear equalizer before maximum likelihood (ML) detection. The linear equalizer allows partial ISI as seen at the input of the ML detector. At high areal densities, the jitter noise is the dominant component of the noise observed in the read back signal. Noise predictive maximum likelihood (NPML) detection improves upon the PRML detection by decorrelating the noise. In this paper, we study the effects of grain density (average number of grains per channel bit) and jitter noise using a low complexity 2D NPML detector recently proposed in [2] over the granular media model. By using correlation properties of the jitter noise, we could achieve >1 .5dB gain in SNR at a chosen grain density. Gains in channel bit densities (CBD) of up to 10% are also observed.


In this paper we describe the X-TRACT workbench, which enables efficient term-based querying against a domain-specific literature corpus. Its main aim is to aid domain specialists in locating and extracting new knowledge from scientific literature corpora. Before querying, a corpus is automatically terminologically analysed by the ATRACT system, which performs terminology recognition based on the C/NC-value method enhanced by incorporation of term variation handling. The results of terminology processing are annotated in XML, and the produced XML documents are stored in an XML-native database. All corpus retrieval operations are performed against this database using an XML query language. We illustrate the way in which the X-TRACT workbench can be utilised for knowledge discovery, literature mining and conceptual information extraction.


The recently published Global Burden of Disease Study 2010 (GBD 2010) contains accurate, contemporary estimates of human morbidity and mortality, with substantial changes in the patterns of illness observed over the last two decades. One of the most significant alterations to these estimates has been the recognition that viral hepatitis is a leading cause of human mortality, with an estimated 1.29 million deaths worldwide in 2010. The global community must act to address emerging health priorities identified by GBD 2010, including the need to provide treatment and care to people living with viral hepatitis, especially in resource-poor settings.


We calculated the mechanical properties, electronic structure, theoretical hardness and optical properties of V4AlC3 using the first-principles method. The results show that V4AlC3 shows a better performance of the resistance to shape change and against uniaxial tensions and has a slight anisotropy on elasticity. Moreover, it is more brittle than α-Nb4AlC3 and Ta4AlC3. The chemical bonding of V4AlC3 is a combination of covalent, ionic and metallic nature. The calculated theoretical hardness is 9.33 GPa, and the weaker covalent bonding of Al–V is responsible for the low hardness of V4AlC3. The optical properties (dielectric function, absorption spectrum, conductivity, energy-loss spectrum and reflectivity) are discussed in detail. It is shown that V4AlC3 has the potential to be used as a promising dielectric material and coating to avoid solar heating.

Civil engineering construction work has always been accompanied by a high proportion of tasks that are either dangerous or unpleasant or both. Enhancing the general working environment and boosting safety levels are critical issues for the industry. Meanwhile, the industry has been slow to embrace IT, and there is substantial scope for the use of technology to boost efficiency, cut costs and improve quality levels in construction. In a bid to address this issue, the Ministry of Land, Infrastructure and Transport launched a five-year project in FY2003 entitled Development of Construction Robots and Associated IT Systems. The aim of the project is to use cutting-edge telecommunications and robotics technology to minimize inefficiencies and eliminate the dangerous and unpleasant aspects of the construction process through the development of specific applications such as IT-equipped construction machinery and construction management systems using three-dimensional data. This paper reports on the research and development work carried out by the authors in connection with the project.

A terminal-based dynamic clustering algorithm is proposed in a multi-cell scenario, where the user could select the cooperative BSs from the predetermined static base stations (BSs) set based on dynamic channel condition. First, the user transmission rate is derived based on linear precoding and per-cell feedback scheme. Then, the dynamic clustering algorithm can be implemented based on two criteria: (a) the transmission rate should meet the user requirement for quality of service (QoS); (b) the rate increment exceeds the predetermined constant threshold. By adopting random vector quantization (RVQ), the optimized number of cooperative BSs and the corresponding channel conditions are presented respectively. Numerical results are given and show that the performance of the proposed method can improve the system resources utilization effectively.

BOREAS' primary goals were to determine how the boreal forest interacts with the atmosphere (via the transfer of gases and energy), how much carbon is stored in the forest ecosystem, how climate change will affect the forest, and how changes in the forest affects weather and climate.


Few works describe how – and to what extent – farmer organisations (FOs) strive to strengthen local life. My PhD research addresses this gap following a central question: what strategies do FOs use as change agents in underdeveloped rural areas? I aim at developing a typology of FOs' strategies as change agents. This paper presents the research setting built to address this matter. Epistemological foundations of this research link to sociology of knowledge and discourse analysis, from a knowledge performativity approach. A development-based conception of agency (capacity development) is unpacked as a governance technology and rendered operational by means of multiple theoretical sources. Literature includes social studies of science and technology, institutional work and innovation intermediation. The research follows an abductive rationale (Schwartz Shea, 2012). The specific research questions serve both the theoretical and the empirical inquiries. The theoretical realm recurs to capacity development as an interpretive reference. On the empirical realm, the research recurs to a multi-sited case study focused on Colombian cocoaproducer FOs in conflicted rural areas.


We construct cryptographic trilinear maps that involve simple, non-ordinary abelian varieties over finite fields. In addition to the discrete logarithm problems on the abelian varieties, the cryptographic strength of the trilinear maps is based on a discrete logarithm problem on the quotient of certain modules defined through the Néron-Severi groups. The discrete logarithm problem is reducible to constructing an explicit description of the algebra generated by two non-commuting endomorphisms, where the explicit description consists of a linear basis with the two endomorphisms expressed in the basis, and the multiplication table on the basis. It is also reducible to constructing an effective Z-basis for the endomorphism ring of a simple non-ordinary abelian variety. Both problems appear to be challenging in general and require further investigation.


The present study aims to determine the effect of administration of rbST in the pre-partum in dairy heifers at the time of first ovulation postpartum. We used 51 Holstein heifers were divided into four groups: rbST with BCS <3.5 (bM) (n = 5), rbST with BCS e" 3,5 (bg) (n = 20), control with BCS <3,5 (cM) (n = 4), and control group ECC e" 3,5 (cG) (n = 22). The groups received two doses of 500 mg of rbST the first application 35 and second 14 days before the expected date of delivery. The control groups received injections of placebo at the same frequency, volume and that the site of application rbST group. When compared to the category of heifers with high BCS, it was observed that 43,75% of bG and cG ovulated 14.28% of the first follicular wave postpartum (P = 0.04). The heifers with high BCS in the control group had a lower percentage of ovulation 14,28% compared to thin heifers treated with rbST 80% (P = 0.002). Comparisons were made with low BCS heifers and heifers treated for ECC under the control group, 80% ovulated and 25%, respectively (P = 0.09). When compared to the categories of heifers of low BCS ECC high in the control group, 14,28% against and 25% ovulated, respectively (P = 0.59). No difference was found (P>0.05) between heifers and heifers with high ECC ECC treated with rbST and down between the treated heifers with high BCS and heifers with low BCS in the control group. It follows that with different dairy heifers body condition, treated with somatotropin have an ovulation rate of the first wave follicular postpartum heifers greater than untreated.


Introduction It is well known that in some fields the average number of citations per publication is much higher than in others (Moed, 2005). For decades, the number of publications and the number of citations have been the two accepted indicators in ranking authors. Recently, alternative indicators which consider both production and impact have been proposed (Dorta-Gonzalez & Dorta-Gonzalez, 2011; Egghe, 2013). However, these indicators based on the h-index do not solve the problem when comparing authors from different fields of science. Given the large differences in citation practices, the development of bibliometric indicators that allow for between-field comparisons is clearly a critical issue (Waltman & Van Eck, 2013). Traditionally, normalization of field differences has usually been based on a field classification system. In said approach, each publication belongs to one or more categories and the citation impact of a publication is calculated relative to the other publications in the same field. In our topic normalization we use the aggregate impact factor of three different sets of journals as a measure of the different dimensions in the citation potential of an author.


Unmanned Aerial Vehicle (UAV) also commonly referred to as drones has found its application in many field of engineering, infrastructure and also the built environment in the recent past. With the use of drones being used for commercial purposes increasing there is a lot of emphasis of how to use these drones for as many applications as possible. This paper highlights the use of drones for mapping large scale rooftop areas to assess solar energy system installation potential. The results show that the drone technology is advantageous compared to the conventional manual survey method in terms of cost, time and resources required when used for large scale areas.


Today face recognition capability of the human visual system plays a significant role in day to day life due to numerous important applications for automatic face recognition. One of the problems with the recent image classification and recognition approaches are they have to extract features on the entire image and on the large grey level range of the image. The present paper overcomes this by deriving an approach that reduces the dimensionality of the image using Shape primitives and reducing the grey level range by using a fuzzy logic while preserving the significant attributes of the texture. The present paper proposed an Image Dimensionality Reduction using shape Primitives (IDRSP) model for efficient face recognition. Fuzzy logic is applied on IDRSP facial model to reduce the grey level range from 0 to 4. This makes the proposed fuzzy based IDRSP (FIDRSP) model suitable to Grey level co-occurrence matrices. The proposed FIDRSP model with GLCM features are compared with existing face recognition algorithm. The results indicate the efficacy of the proposed method.


This study is focused on the development and demonstration of a continuum damage and discrete crack (CDDC) approach for fatigue damage characterization and post-fatigue residual strength prediction of notched composite specimens subjected to tension. In order to capture both the fatigue cycle driven material degradation and discrete damage induced stress concentration and redistribution, an overlapped element approach is developed based on a combined user-defined material and element formulation. An Abaqus element coupled with UMAT for fatigue damage and failure characterization is used to detect the location of failure initiation while the discrete crack network (DCN) based UEL is applied to insert a crack without remeshing. The intensified stress field induced by the newly inserted matrix crack is used for the evaluation of failure initiation and stiffness degradation. A stress-life (SN) approach is applied to perform the strength degradation prediction associated with the intraand interply damage mode. To demonstrate the applicability and validity of the CDDC based toolkit for Abaqus, a blind followed by a re-calibrated fatigue failure prediction is performed for a notched coupon of [30, 60, 90, -60, -30]2S followed by its postfatigue residual strength prediction. The predicted fatigue failure progression and its stiffness drop against cycle curves are compared with the test data provided by the Air Force Research Lab (AFRL).

Recent esophagofiberscope has almost complete capabilities for the diagnostic fields of the esophageal diseases. But its contribution to the therapeutic fields has rarely been made. For the removal of the foreignbody from the esophagus and stomach, a kind of special forceps was devised. This was inserted through the biopsy channel of the esophagofiberscope. The foreignbodies were captured under visual control and taken off with the fiberscope altogether. The demonstration of the forceps and some clinical results will be reported. Sometimes the silk suture could be found at the stoma after surgery. For the removal of it the special forceps, named "suture-cutting forceps", was newly devised. This forceps was inserted through the biopsy channel of the esophagofiberscope and able to cut and take off the suture under visual control.


Models for teaching programming have been suggested in the literature. Interviews of teachers indicate that they normally do not relate to such models. Since referring explicitly to didactic models in teaching may improve learning, using models seems preferable. Models concerning learning and teaching are suggested in the paper.


Hip arthrodesis is still a major option for the painful arthritic hip in the third world, where total hip prostheses are seldom available or too expensive for the patient. Various procedures for hip fusion have been described in the literature; they are often complex, frequently need a long period of post-operative immobilisation and are coupled with a considerable failure rate.

A new simple technique for hip arthrodesis is described without dislocating the hip preoperatively in order to maintain the oxygen concentration in the femoral head, using a self devised plate and requiring no post-operative immobilisation.

During a three year period the procedure was performed in 22 patients by the same surgeon. In all cases the indication for hip fusion was hip osteo-arthritis. The cause of osteo-arthritis was in 46% hip destruction by tuberculosis, in 23% aseptic osteonecrosis of the femoral head, mostly linked to sickle cell anaemia, in 8% complications of trauma of the hip, in 8% slipped upper femoral epiphysis and in 15% primary arthritis. Two had concurrent femoral osteotomy for correcting malposition of the limb and one had during the same procedure a femoral diaphysis osteotomy with placement of a Wagner elongating device in order to proceed with a callotasis. Mean follow up was 15.4 months. All hips, except one, achieved a solid fusion by radiographic and clinical criteria between 6 and 12 months after surgery. The failure of fusion was in the oldest patient (63 years) who presented loosening of plate and screws due to an advanced degree of osteoporosis. One superficial infection occurred that resolved under antibiotics.

The influence of cattle slurry applied to a silage crop was studied in three successive years. Each year, 40 t slurry ha-1 were applied in two equal applications. Unfertilised and mineral-fertilised field plots were used as controls. Before spreading, the slurry was contaminated with spores of Clostridium tyrobutyricum (103–104 g-1 FM). The fields were harvested two times a year, the yields were measured and the chemical composition and bacterial content of the crop were determined. The fresh material was chopped, ensiled without additives, and stored for 100 days before opening. The bacterial content of the soil surface and available N, P and K in soil were measured. Slurry did not seem to have any significance in a short-term perspective. Yield increase as an effect of slurry application was slight and inconsistent in comparison with the yield from unfertilised plots. The number of Clostridium or Bacillus spores in the soil surface was not significantly affected by the slurry application, nor was the number of detrimental organisms in harvested crop at ensiling. Nonetheless, in three of the four silages in which clostridial spores were estimated, numbers were higher in silage made from slurry-treated crops. © 1997 SCI.


Rheumatoid Arthritis (RA) has been associated with several autoantibodies, including antiperinuclear factor, anti-keratin antibodies, anti-filaggrin antibodies, and anti-Cyclic Citrullinated Peptide (anti-CCP) antibodies. Most studies found that anti-CCP antibodies are only detected in Juvenile Rheumatoid Arthritis (JRA) patients with positive Rheumatoid Factor (RF). In our center we experimentally observed that children with Juvenile Idiopathic Arthritis (JIA) that tested positive for anti-CCP Abs were also tested positive for RF. In seven years of follow-up of these 86 patients, 63 (73.2%) developed RA. It can be hypothesized that the antibodies against CCP plays an important role in progression of the JIA towards RA. On the other hand anti-CCP Abs may play a role in the pathogenesis of RA. Further studies are needed to clarify this association.


In this paper, we study the level set estimation of a spatial-temporally correlated random field by using a small number of spatially distributed sensors. The level sets of a random field are defined as regions where data values exceed a certain threshold. We propose a new active sparse sensing and inference scheme, which can accurately extract level sets in a large random field with a small number of sensors strategically and sparsely placed in the random field. In the proposed active sparse sensing scheme, a central controller dynamically selects a small number of sensing locations according to the information revealed from past measurements, with the objective to minimize the expected level set estimation errors. The expected estimation error is explicitly expressed as a function of the sensing locations, and the results are used to formulate optimal and sub-optimal selection of sensing locations. Simulation results demonstrate that the proposed algorithms can achieve significant performance gains over baseline passive sensing algorithms that do not proactively select the sensing locations.


A feature of the modern market is the pursuit of strong competitiveness, especially in the sector related to information technologies (IT). Wile new companies are emerging in which IT professionals carry out their professional tasks very intensively, often working under conditions of severe stress in unregulated working hours. For a team of employees to be productive a supervisor who is wise, well-educated and sensitive to the employees' needs is indispensable. We assumed that high level of quality of life sense of IT professionals characterized by high level of leadership competency can lead to their better productivity and management of their IT teams. Therefore we investigate the correlations between leadership competency self-esteem, human potentiality (spiritual sensitivity) and quality of life of IT professionals in Poland, a transition economy. The research data is collected by an online survey with the use of our novel questionnaires among 420 IT professionals in the region of Lower Silesia of Poland. The results of this study show that leadership competencies correlate with human potentiality and quality life of IT professionals in transition economies. The highest quality of life seems to be in companies where the managers manifest a high level of leadership competency. The human potentiality we understand as a kind of sensitivity, composed of abilities related to everyday, observable human activity, serving adaptive problems solving and attaining goals, principally in the moral field. Also, we plan the test procedure, and describe the psycho-social and economic tools, which serve to measure human potentiality (the Human Potentiality Inventory HP), quality of life (the Quality of Life Questionnaire) and we will show the methodological process of creating them. They all are novel, the shorter adaptations of original versions. We guided our study according to two research questions: 1. Does leadership competencies self-esteem correlate with human potentiality and quality of life among IT professionals working in companies in Poland, a transition economy? 2. What are the most important dimensions of leadership competencies correlating with human potentiality and quality of life among IT professionals in Poland? Our study contributes to expanding the existing research stream concerning leadership competencies selfesteem, human potentiality and quality of life among IT professionals working in transition economies.

Leaders' self-efficacy has recently been identified as a critical component in the success of educational reform. In educational policy and leadership, little attention has been paid to leaders' self-efficacy beliefs as they go about the implementation of Common Core State Standards (CCSS). This study seeks to understand leaders' CCSS self-efficacy by examining the level of CCSS-focused engagement and the degree of leaders' network connectedness from a social learning perspective. Findings suggest leaders who report higher levels of CCSS-focused engagement tend to be more efficacious about implementing CCSS. Such a relationship is mediated by leaders' social network position in providing CCSS advice and work effort recognition to their fellow administrators.

Timber was not just a second-rate material which was adopted for reasons of economy. In the early Middle Ages very substantial churches might be built in wood until the eleventh century when there was a decisive shift in favour of masonry, and thereafter most new parish churches were built in stone. Timber churches frequently used wood in a different manner to secular buildings. From the earliest churches onwards, the walls seem to have been constructed with close-set or even contiguous timbers. Close-set studs (wall supports) are often used on the front of late medieval secular buildings as a form of display, but rarely used on the less visible portions where economies could be made. However, in timber churches no such compromise was made.


Dear Colleagues and Friends, One of the President's tasks is to deliver a message to the members and guests of the Association. My task today, after the brilliant presidential address given by Pascal Vouhe last year, followed by a spectacular musical performance, is particularly difficult: it is like organizing the Olympic games after those in Beijing in 2008. Truly impossible to outdo! Therefore, my speech will be unpretentious and mainly related to our work and our daily lives. First, let me explain the title of my talk. When I was a research fellow at the University of Alabama in Birmingham, USA, every Sunday my wife and I used to take our little girl, Cecilia, to a park close to our house, so she could play with the other children. Once, I took a picture (Fig. 1), which I showed to the mother of the other children. She looked at it and after a few moments said: 'The beauty of the differences!' This short, spontaneous comment remained indelible in my mind and became a sort of inspiring motif in my life and in my profession. It means appreciation, respect, acceptance, understanding and tolerance for different opinions, attitudes, cultures and backgrounds. It means 'open mindedness' and therefore 'potential for growth'. Historically, every time differences have been recognized, appreciated and incorporated, the final result has been progress and an advance in civilization. Let us consider the glorious history of Venice: a millennium of independence and splendour! For centuries, Venice was a flourishing trade centre lying between Europe and the Byzantine Empire, the Islamic world and the East. By the late 13th century, Venice was the most prosperous city in all Europe. The Grand Canal, shaped like an inverted letter S (Fig. 2), is an uninterrupted sequence of splendid palaces, reflecting a great variety of influences and cultures from far away, and incorporating different styles (Byzantine, Gothic, Renaissance, Classical and Baroque etc.) (Fig. 3). Venice's leading families vied with each other to build the grandest palaces, employing the greatest architects and the most talented artists. Every wealthy Venetian wanted his palace to be the most beautiful and unique. Therefore, the Grand Canal is a hymn to the differences, and the differences are a hymn to beauty! I will try to transfer these concepts to our profession, first considering education and training.
