Teachers’ Professional Community in Restructuring Schools

Professional community among teachers, the subject of a number of recent major studies, is regarded as an ingredient that may contribute to the improvement of schools. The research reported in this article is grounded in the assumption that how teachers interact with each other outside of their classrooms may be critical to the effects of restructuring on students. The analysis focuses on the type of professional community that occurs within a school and investigates both the organizational factors that facilitate its development and its consequences for teachers’ sense of responsibility for student learning. The findings suggest that wide variation in professional community exists between schools, much of which is attributable to both structural features and human resources characteristics, as well as school level. Implications for current school reform efforts are discussed.
Roma pupils’ identification with school in Slovenia and Serbia: case studies

The research presented in this paper aims to challenge the belief held by some education professionals that Roma pupils do not value education. The research sample included groups of Roma pupils from two countries (Slovenia and Serbia) and from different socio-economic backgrounds. The results suggest that the majority of the pupils are aware of the importance of education. However, there are significant differences in their sense of identification with school. Roma pupils from families whose socio-economic background is comparable to that of the majority population are more appreciative of educational success, feel more accepted by teachers and classmates and are better able to connect education with their own lives. Roma pupils from families of lower socio-economic background associate school with failure, discrimination and rejection by teachers and classmates. Barriers to these pupils’ learning and social participation may be related to their tendency to drop out of the compulsory education.
Large-Scale Multi-View Spectral Clustering via Bipartite Graph

In this paper, we address the problem of large-scale multi-view spectral clustering. In many real-world applications, data can be represented in various heterogeneous features or views. Different views often provide different aspects of information that are complementary to each other. Several previous methods of clustering have demonstrated that better accuracy can be achieved using integrated information of all the views than just using each view individually. One important class of such methods is multi-view spectral clustering, which is based on graph Laplacian. However, existing methods are not applicable to large-scale problem for their high computational complexity. To this end, we propose a novel large-scale multi-view spectral clustering approach based on the bipartite graph. Our method uses local manifold fusion to integrate heterogeneous features. To improve efficiency, we approximate the similarity graphs using bipartite graphs. Furthermore, we show that our method can be easily extended to handle the out-of-sample problem. Extensive experimental results on five benchmark datasets demonstrate the effectiveness and efficiency of the proposed method, where our method runs up to nearly 3000 times faster than the state-of-the-art methods.
A fast simulation model for a Permanent Magnet Synchronous Generator (PMSG) drive system

This paper presents a novel average voltage estimation model of a Voltage Source Inverter (VSI) for Permanent Magnet Synchronous Generator (PMSG) drive systems which when included in a complete electromechanical system model results in significantly reduced simulation times. Sinusoidal Pulse Width Modulation (PWM) control techniques are implemented with the proposed model enabling effective control of generator current, power, electromagnetic torque and DC link voltage control. A detailed back to back VSI switching model for a fractional horsepower PMSG is used as a benchmark against which the results of the average voltage model are compared. Both models have been implemented in the PORTUNUS simulation package and verified against an experimental back to back converter module connected to a variable speed PMSG. The results show good agreement between both simulation models and experimental data with the average voltage estimation model accurately reproducing generator currents over the linear and over-modulation regions, with the advantage of reducing simulation times by up to a factor of 10 compared to the switching model. The simulation results show the capability of the proposed average voltage estimation model over a wide range of speed and can be used to study and analyze the performances of variable speed PMSG energy conversion system.
Gene Expression Profiling Reveals Defined Functions of the ATP-Binding Cassette Transporter COMATOSE Late in Phase II of Germination1[W][OA]

Phase II of germination represents a key developmental stage of plant growth during which imbibed seeds either enter stage III of germination, completing the germination process via radicle protrusion, or remain dormant. In this study, we analyzed the influence of the peroxisomal ATP-binding cassette transporter COMATOSE (CTS) on the postimbibition seed transcriptome of Arabidopsis (Arabidopsis thaliana) and also investigated interactions between gibberellin (GA) and CTS function. A novel method for analysis of transcriptome datasets allowed visualization of developmental signatures of seeds, showing that cts-1 retains the capacity to after ripen, indicating a germination block late in phase II. Expression of the key GA biosynthetic genes GA3ox1 and 2 was greatly reduced in cts seeds and genetic analysis suggested that CTS was epistatic to RGL2, a germination-repressing DELLA protein that is degraded by GA. Comparative analysis of seed transcriptome datasets indicated that specific cohorts of genes were influenced by GA and CTS. CTS function was required for expression of the flavonoid biosynthetic pathway. Confocal imaging demonstrated the exclusive accumulation of flavonoids in the epidermis of wild-type seeds. In contrast, flavonoids were absent from cts and kat2-1 mutant seeds, but accumulated following the application of sucrose, indicating an essential role for β-oxidation in inducing flavonoid biosynthetic genes. These results demonstrate that CTS functions very late in phase II of germination and that its function is required for the expression of specific gene sets related to an important biochemical pathway associated with seedling establishment and survival.
Effects of Changing Economic Conditions on Managerial Job Changes and Careers

SUMMARY Career theories and popular beliefs support the view that careers are series of job changes which are normatively linked to common themes, are continuous, are hierarchically progressive, and are under the control of the career-making person. This study reports an age-controlled analysis of the job changes, from 1980 to 1992, of a sample of 832 UK managers, randomly sampled from the membership of the Institute of Management. Following the methodology developed by Alban-Metcalfe and Nicholson (1984), sample members completed a questionnaire in which they provided details of every job change they had experienced in the relevant period, including nature of change and reasons for change. The results suggested that during the recession of 1989–92 British managers moved from a situation of predominantly proactive, career-oriented upward moves, to one of predominantly reactive, organizationally induced sideways and downward moves, including redundancies. Implications for career theory and for the career development and orientations of managers and others are discussed. The continuing usefulness of the concept ‘career’ is questioned. This paper was first presented at the Academy of Management Annual Convention in Atlanta, Georgia, August 1993.
The Children’s Perceived Locus of Causality Scale for Physical Education

A mixed methods design was applied to evaluate the application of the Perceived Locus of Causality scale (PLOC) to preadolescent samples in physical education settings. Subsequent to minor item adaptations to accommodate the assessment of younger samples, qualitative pilot tests were performed (N = 15). Children’s reports indicated the need for further revisions to the items, resulting in the Children’s PLOC (C-PLOC). In a second study involving a larger sample of 9–12 year old children (N = 429), the questionnaire was evaluated using quantitative methods. The five factor structure hypothesized based on self-determination theory was confirmed. Discriminant validity and reliability of the subscales was largely supported, but require confirmation in future research. Age was not found to be significantly related to children’s motivational styles. Taken together, initial results provide support for the suitability of the C-PLOC for the assessment of motivation in 9–12 year old children in physical education.
Association of polymorphisms of the transporter associated with antigen processing (TAP2) gene with pulmonary tuberculosis in an elderly Japanese population

The transporter associated with antigen processing 2 (TAP2) gene is involved in the immunological response to tuberculosis (TB) infection. Variations in the TAP2 gene have been associated with TB infection in small population studies in India, Columbia, and Korea. We investigated the association of TAP2 polymorphisms with TB susceptibility in an elderly Japanese population. We analyzed samples from consecutive autopsy cases (n = 1850) registered in the Japanese Geriatric SNP Research database. TB was diagnosed pathologically by TB granuloma on autopsy samples. There were 289 cases and 1529 controls. Twenty‐four single nucleotide variations (SNVs), including four missense variations in the TAP2 region, were genotyped using the Illumina Infinium Human Exome BeadChip array. Of the 24 SNVs in the TAP2 gene, rs4148871, rs4148876 (R651C), and rs2857103 showed statistically significant associations with TB susceptibility, and rs4148871 and rs2857103 also showed significant genotypic associations in a dominant allele model adjusted for age, sex, and smoking. Haplotype analysis showed that TAP2 allele *0103 conferred an increased TB risk (OR = 1.48, p = 0.0008), while the TAP2 *0201 allele was protective against TB (OR = 0.73, p = 0.0007). Our results suggest that TAP2 polymorphisms influence TB susceptibility in a Japanese population.
Learning and Education Experience in System Dynamics of Management Students: Case Studies

Article describes experiences in the teaching of a modelling and simulation course for students at Faculty of Organizational Sciences. The course consists of time-continuous simulation based on System Dynamics SD and discrete event simulation DES. It is held in the 3rd year of studies, at which point students have taken courses in mathematics, statistics, theory of systems, as well as organizational and economic courses. The final grade for the course is derived from the student's project and written exam. Students took part in an experiment where they had to solve a managerial decision problem supported by a simulation model. Experimental results were then analysed and discussed in the students' projects. Students' contributions were part of their final grade. The results show that students, taking the course of Modelling and Simulation, thought that application of the simulation model contributes to a greater understanding of the problem, the faster finding of solutions, and enhanced confidence of the participants. The results are explained and discussed using a learning model.

A Qualitative Study of Moral Reasoning of Young Elite Athletes

Based on game reasoning theory (Shields & Bredemeier, 2001) and related research, the present study aimed at describing young elite athletes’ perceptions of rules compliance and transgression in competitive settings, as well as the underlying reasons for these actions. Semi-structured interviews were conducted with 10 young elite athletes. The qualitative analysis showed that respect and transgression of rules in competitive settings were perceived to depend upon the athletes’ individual characteristics (e.g., desire to win), their social environment (e.g., coach’s pressure, team norms), sports values and virtues (e.g., fair play, the effort ethic), and modern sports rewards (e.g., media recognition, financial rewards). These results confirmed and expanded game reasoning theory and illustrated moral disengagement mechanisms (Bandura et al., 1996) in the sport domain.
Effects of an Imagery Mnemonic on Second Language Recall and Comprehension

University students with some educational background in French as a second language used an imagery-based hook mnemonic and rote rehearsal to learn different sets of French words. The hook technique involved associating the new items with an overlearned series of French stimulus words and images, which could be retrieved during recall using a number code. The rote condition involved the technique without imagery. The recall items, which were presented along with their translation equivalents on the study trial, varied in familiarity and concreteness. Recall following one study trial was approximately three times higher for words learned by imagery than by rote. This effect was only slightly qualified by familiarity and concreteness, which also affected recall. Translation tests given before and (unexpectedly) one day after the recall experiment showed that correct translations of relatively unfamiliar items increased about twice as much after study by imagery than after rote study. Thus imagery simultaneously facilitated both recall and comprehension. The practical and theoretical implications are discussed.
Endogenous human cytomegalovirus gB is presented efficiently by MHC class II molecules to CD4+ CTL

Human cytomegalovirus (HCMV) infects endothelial, epithelial, and glial cells in vivo. These cells can express MHC class II proteins, but are unlikely to play important roles in priming host immunity. Instead, it seems that class II presentation of endogenous HCMV antigens in these cells allows recognition of virus infection. We characterized class II presentation of HCMV glycoprotein B (gB), a membrane protein that accumulates extensively in endosomes during virus assembly. Human CD4+ T cells specific for gB were both highly abundant in blood and cytolytic in vivo. gB-specific CD4+ T cell clones recognized gB that was expressed in glial, endothelial, and epithelial cells, but not exogenous gB that was fed to these cells. Glial cells efficiently presented extremely low levels of endogenous gB—expressed by adenovirus vectors or after HCMV infection—and stimulated CD4+ T cells better than DCs that were incubated with exogenous gB. Presentation of endogenous gB required sorting of gB to endosomal compartments and processing by acidic proteases. Although presentation of cellular proteins that traffic into endosomes is well known, our observations demonstrate for the first time that a viral protein sorted to endosomes is presented exceptionally well, and can promote CD4+ T cell recognition and killing of biologically important host cells.
LncRNA-HIT Functions as an Epigenetic Regulator of Chondrogenesis through Its Recruitment of p100/CBP Complexes

Gene expression profiling in E 11 mouse embryos identified high expression of the long noncoding RNA (lncRNA), LNCRNA-HIT in the undifferentiated limb mesenchyme, gut, and developing genital tubercle. In the limb mesenchyme, LncRNA-HIT was found to be retained in the nucleus, forming a complex with p100 and CBP. Analysis of the genome-wide distribution of LncRNA-HIT-p100/CBP complexes by ChIRP-seq revealed LncRNA-HIT associated peaks at multiple loci in the murine genome. Ontological analysis of the genes contacted by LncRNA-HIT-p100/CBP complexes indicate a primary role for these loci in chondrogenic differentiation. Functional analysis using siRNA-mediated reductions in LncRNA-HIT or p100 transcripts revealed a significant decrease in expression of many of the LncRNA-HIT-associated loci. LncRNA-HIT siRNA treatments also impacted the ability of the limb mesenchyme to form cartilage, reducing mesenchymal cell condensation and the formation of cartilage nodules. Mechanistically the LncRNA-HIT siRNA treatments impacted pro-chondrogenic gene expression by reducing H3K27ac or p100 activity, confirming that LncRNA-HIT is essential for chondrogenic differentiation in the limb mesenchyme. Taken together, these findings reveal a fundamental epigenetic mechanism functioning during early limb development, using LncRNA-HIT and its associated proteins to promote the expression of multiple genes whose products are necessary for the formation of cartilage.
Ecquid Novi – the search for a definition

News people, researchers and the public alike have addressed the issue of news over centuries. Still, this fleeting, elusive, but essential feature of journalism defies practical definition, let alone scientific specification. The research problem stated in this article is that little progress has been made to find an overarching conceptualisation of the term news: What does news consist of, how can one define it, and will there be universal acknowledgement if such a definition should exist? A literature and historical study was undertaken in which the origins and concepts of news were analysed, while the underlying paradigmatic assumption was that of a functionalist approach to media and society. The purpose of this article is then to explore four of the crucial or key theoretical and research dimensions of news as it traditionally developed over a number of decades, and which have contributed, but also hindered, the quest for a definition of news, namely: objectivity; typologies of news values; news preferences and reading habits; new news concepts; as well as training and education. Examples to clarify points made are taken from international journalism. It is concluded that a heuristic model for the development of a news definition should extrapolate and build on these four dimensions of news.
Runtime recovery actions selection for sporadic operations on public cloud

Sporadic operations such as rolling upgrade or machine instance redeployment are prone to unpredictable failures in the public cloud largely because of the inherent high variability nature of public cloud. Previous dependability research has established several recovery methods for cloud failures. In this paper, we first propose eight recovery patterns for sporadic operations on public cloud. We then present the filtering process which filters applicable recovery patterns. We propose an automation mechanism to automatically generate recovery actions for those applicable recovery patterns based on our resource state transition algorithm. We also propose a methodology to evaluate the recovery actions generated for the applicable recovery patterns based on the recovery evaluation metrics of Recovery Time, Recovery Cost, and Recovery Impact. This quantitative evaluation will lead to selection of the acceptable recovery actions. We propose two recovery actions selection mechanisms: one is based on user constraints of the recovery evaluation metrics, and the other one is based on Pareto set searching algorithm. We implement a recovery service and illustrate its applicability by recovering from errors occurring in the rolling upgrade operation on AWS cloud.
Real-Time Optimization of Web Publisher RTB Revenues

This paper describes an engine to optimize web publisher revenues from second-price auctions. These auctions are widely used to sell online ad spaces in a mechanism called real-time bidding (RTB). Optimization within these auctions is crucial for web publishers, because setting appropriate reserve prices can significantly increase revenue. We consider a practical real-world setting where the only available information before an auction occurs consists of a user identifier and an ad placement identifier. The real-world challenges we had to tackle consist mainly of tracking the dependencies on both the user and placement in an highly non-stationary environment and of dealing with censored bid observations. These challenges led us to make the following design choices: (i) we adopted a relatively simple non-parametric regression model of auction revenue based on an incremental time-weighted matrix factorization which implicitly builds adaptive users' and placements' profiles; (ii) we jointly used a non-parametric model to estimate the first and second bids' distribution when they are censored, based on an on-line extension of the Aalen's Additive model. Our engine is a component of a deployed system handling hundreds of web publishers across the world, serving billions of ads a day to hundreds of millions of visitors. The engine is able to predict, for each auction, an optimal reserve price in approximately one millisecond and yields a significant revenue increase for the web publishers.
Commuting Stress: Problems of Definition and Variable Identification

Bien que les chercheurs reconnaisssent l'experience du changement comme source potentielle de stress, les resultats concernant son impact sur des conduites variees individuelles ou organisationnelles ont ete peu concluants. Dans le present article, une revue des etudes qui examinerent l'influence potentielle du stress de changement sur des mesures de contraintes psychologiques, physiologiques et comportementales, est proposee et releve des contradictions. Un modele est decrit, liant des mesures objectives et subjectives de l'agent de stress, directement ou indirectement aux conduites. Il est suggere qu'en incluant plusieurs moderateurs critiques, par exemple le controle, la predictibilite et l'urgence dans le temps, des predictions emanant de stimuli de stress de changement pourraient etre mises en avant.
