The Use of Repression as a Response to Domestic Dissent

This study contributes to our understanding of government repression in response to internal threats using a quantitative approach. In contrast to previous research, it focuses on the outbreak of state terror and on how different types of domestic dissent influence the risk of such severe state-sponsored violence. The empirical analysis distinguishes between demonstrations, strikes, riots, guerrilla attacks and revolutions, which vary in the level of violence and in the level of organisation that is behind the dissent, and analyses how those forms of threat affect the probability of repression onset. The empirical model controls for a potentially non-linear relationship between level of democracy and repression and investigates how dissent influences state terror in different political regimes. The analysis employs a logit model to test the link between dissent and repression in 149 countries between 1977 and 2002. The findings suggest that only guerrilla warfare increases the probability of repression onset. Democratic political regimes not only decrease the risk of state terror per se, but also dampen the effect of large-scale violent dissent on the risk of repression. The results also show that the longer a country manages to avoid repression, the less likely it is to suffer from repression again.
The Kerr/CFT Correspondence and String Theory

The Kerr/CFT correspondence is a holographic duality between a two dimensional chiral conformal field theory (CFT) and the very near horizon limit of an extremal black hole, which includes an AdS{sub 2} structure. To understand the dual chiral CFT{sub 2}, we apply the Kerr/CFT correspondence to a certain class of black holes embedded in string theory, which include the D1-D5-P and the Breckenridge-Myers-Peet-Vafa black holes, and obtain the correct entropies for the black holes microscopically. These have an AdS{sub 3} structure in the near horizon geometry and an AdS{sub 2} structure in the very near horizon geometry. We identified one of the two Virasoro symmetries in the nonchiral CFT{sub 2} dual to the AdS{sub 3}, i.e., in the AdS{sub 3}/CFT{sub 2}, with the Virasoro symmetry in the chiral CFT{sub 2} dual to the AdS{sub 2}, i.e., in the Kerr/CFT correspondence. We also discuss a way to understand the chiral CFT{sub 2} dual to generic extremal black holes. A kind of universality for the very near horizon geometries of extremal black holes will be important for the validity of the Kerr/CFT correspondence. Based on this analysis, we propose that the Kerr/CFT correspondence can be understood as a decoupling limit in whichmore » only the ground states remain. « less
When Forensic Examiners Disagree: Bias, or Just Inaccuracy?

Background: Previous investigators have suggested that bias might account for the disparate rates at which examiners conclude that defendants are competent to stand trial (CST). This article describes three computer studies of how biases and imperfect accuracy might affect rates of disagreement. Methods: Study 1 assumed that examiners could discriminate between competent and incompetent accurately (effect size = 1.81, ROC area = 0.90) and used computer simulation of 20,000 pairs of CST evaluations to determine how different judgment thresholds (e.g., thresholds exemplifying biases toward opinions that defendants were competent or incompetent) would elevate disagreement rates above those expected through chance error alone. Studies 2 and 3 evaluated the assumptions of Study 1 using previously published data to make inferences about examiner accuracy and threshold locations. Results: Imperfect accuracy alone would often explain much between-examiner disagreement, even if examiners approached evaluations with distinct biases. Results from Studies 2 and 3 suggested that assumptions used in Study 1 were reasonable. Conclusion: Many instances of between-examiner disagree might be attributable to imperfect accuracy that expresses itself in random errors, rather than to examiner biases that imply different thresholds for judging defendants’ competence.
Statistical Methods for Construction of Neural Networks

Despite all the progress in neural networks the technology is still brittle and sometimes difficult to apply. Automatic construction of networks and proper initialization of their adaptive parameters are the key factors to create robust neural networks. Methods of ini-tialization of MLPs are reviewed and new methods based on statistical discriminants and logical rules are suggested. These methods in many cases achieve higher accuracy before learning starts than random initialization achieves after the learning process finishes.
Description of a new species, Toxorhynchites (Toxorhynchites) tyagii (Diptera: Culicidae), from Nilgiri hills, Western Ghats, southern India.

Specimens of Toxorhynchites (Toxorhynchites) tyagii, sp. n. , were collected from the fringe areas of Gudaloor town, Ooty in the Nilgiri hills at an altitude of 1000 m above sea level in Western Ghats ranges in southern India during October 2011 and from Darjeeling ranges in the northern hilly region of Raymatang TG in Jalpaiguri district, West Bengal, in eastern India during February 2012. The adults, pupa and fourth-instar larva of this species are described and illustrated to distinguish it from Toxorhynchites (Tox.) splendens and Toxorhynchites (Tox.) edwardsi, which are the closest allies of Tx. (Tox.) tyagii. Besides possessing remarkable distinguishing male genital characteristics, Tx. tyagii differs from Tx. splendens also by the presence of conspicuous yellow scale-patches over the wing root that extend to the scutellum, and differs from Tx. edwardsi by having midtarsomeres 3-5 all dark whereas in Tx. edwardsi tarsomeres 3 and 4 and a larger part of 5 are white.
OSMRec Tool for Automatic Recommendation of Categories on Spatial Entities in OpenStreetMap

In this demonstration, we present OSMRec, a command line utility and JOSM plugin for automatic recommendation of tags (categories) on newly created spatial entities in OpenStreetMap (OSM). JOSM allows downloading parts of OSM, editing the map (e.g. inserting, deleting, annotating with tags spatial entities) and re-uploading the updated part back on OSM. OSMRec plugin exploits already annotated entities within OSM to train category classification models and utilizes these models in order to recommend OSM categories for newly inserted spatial entities in OSM.
A numerical study on indentation properties of cortical bone tissue: influence of anisotropy.

PURPOSE The purpose of this study is to investigate the effect of anisotropy of cortical bone tissue on measurement of properties such as direction-dependent moduli and hardness. METHODS An advanced three-dimensional finite element model of microindentation was developed. Different modelling schemes were considered to account for anisotropy of elastic or/and plastic regimes. The elastic anisotropic behaviour was modelled employing an elasticity tensor, and Hill's criteria were used to represent the direction-dependent post-yield behaviour. The Oliver-Pharr method was used in the data analysis. RESULTS A decrease in the value of the transverse elasticity modulus resulted in the increased material's indentation modulus measured in the longitudinal direction and a decreased one in the transverse direction, while they were insensitive to the anisotropy in post-elastic regime. On the other hand, an increase in plastic anisotropy led to a decrease in measured hardness for both directions, but by a larger amount in the transverse one. The size effect phenomenon was found to be also sensitive to anisotropy. CONCLUSIONS The undertaken analysis suggests that the Oliver-Pharr method is a useful tool for first-order approximations in the analysis of mechanical properties of anisotropic materials similar to cortical bone, but not necessarily for the materials with low hardening reserves in the plastic regime.
Determination of the exercise intensity that elicits maximal fat oxidation.

PURPOSE The aim of this study was to develop a test protocol to determine the exercise intensity at which fat oxidation rate is maximal (Fat(max)). METHOD Eighteen moderately trained cyclists performed a graded exercise test to exhaustion, with 5-min stages and 35-W increments (GE(35/5)). In addition, four to six continuous prolonged exercise tests (CE) at constant work rates, corresponding to the work rates of the GE test, were performed on separate days. The duration of each test was chosen so that all trials would result in an equal energy expenditure. Seven other subjects performed three different GE tests to exhaustion. The test protocols differed in stage duration and in increment size. Fat oxidation was measured using indirect calorimetry. RESULTS No significant differences were found in Fat(max) determined with the GE(35/5), the average fat oxidation of the CE tests, or fat oxidation measured during the first 5 min of the CE tests (56 +/- 3, 64 +/- 3, 58 +/- 3%VO(2max), respectively). Results of the GE(35/5) protocol were used to construct an exercise intensity versus fat oxidation curve for each individual. Fat(max) was equivalent to 64 +/- 4%VO(2max) and 74 +/- 3%HR(max). The Fat(max) zone (range of intensities with fat oxidation rates within 10% of the peak rate) was located between 55 +/- 3 and 72 +/- 4%VO(2max). The contribution of fat oxidation to energy expenditure became negligible above 89 +/- 3%VO(2max) (92 +/- 1%HR(max)). When stage duration was reduced from 5 to 3 min or when increment size was reduced from 35 to 20 W, no significant differences were found in Fat(max), Fat(min), or the Fat(max) zone. CONCLUSION It is concluded that a protocol with 3-min stages and 35-W increments in work rate can be used to determine Fat(max). Fat oxidation rates are high over a large range of intensities; however, at exercise intensities above Fat(max), fat oxidation rates drop markedly.
Lateral frontal cortical contribution to memory

Abstract Recent studies of the mnemonic effects of selective lesions within the lateral frontal cortex in the monkey have suggested that the mid-dorsolateral region may be a specialized system for the monitoring and manipulation of information within working memory. This impairment appears against a background of normal performance on several basic mnemonic tasks. By contrast, a more severe impairment follows damage to the mid-ventrolateral frontal region. Functional activation studies with normal human subjects have confirmed the suggestion from the animal work that the mid-dorsolateral region is involved in the monitoring and manipulation of information within working memory.
High-efficiency multiple-output DC-DC conversion for low-voltage systems

This versatile power converter controller provides dual outputs at a fixed switching frequency and can regulate either output voltage or target system delay (using an external L-C filter). In the voltage regulation mode, the output voltage is monitored with an analog-digital (A/D) converter, and the feedback compensation network is implemented digitally. The generation of the pulsewidth modulation (PWM) signal is done with a hybrid delay line/counter approach, which saves power and area relative to previous implementations. Power devices are included on chip to create the two independently regulated output PWM signals. The key features of this design are its low-power dissipation, reconfigurability, use of either delay or voltage feedback, and multiple outputs.
Spies, surveillance and stakeouts: monitoring Muslim moves in British state schools

This article will provide a critique of the PVE initiative and its implementation within the context of primary education following the events of 9/11, the 2001 riots and 7/7. Drawing upon empirical data I will argue that the monitoring of young Muslims and ‘extremism’ is problematic and reinforces the logics of Islamophobia through practices of governmentality. Moreover I will examine how whilst the monitoring of extremism is prioritized in many schools, training for teachers on race equality, tolerance and accepting difference is weak if not absent. This, I suggest, demonstrates a clear manifestation of contemporary hegemonic post-racial politics which increasingly silences the critique of institutional racism. Additionally this article will explore how Muslims in the sphere of education have been implicated and problematised against the backdrop of a ‘muscular liberalism’ intent on the return of assimilationist discourses.
Meeting the needs of the workplace and the learner through work‐based learning

Purpose – The purpose of this paper is to discuss the value and learning potential of work‐based projects to both worker‐researchers and their organisations.Design/methodology/approach – Within the School of Health, Community and Education Studies at Northumbria University, work‐based learning (WBL) programmes are becoming increasingly important as a vehicle to enable individuals to gain academic credit and qualifications through developing their personal and professional repertoire of skills and knowledge, and also as a mechanism to improve organisational practice/change. To this end the School has used work‐based projects (WBPs) to work innovatively in partnership with employers. Three short case studies are used to explore how WBPs have been used effectively to meet the particular needs of both the workplace and the learner and to discuss the challenges that these initiatives pose in higher education (HE). Findings – The paper finds that a number of identified issues currently challenging the authors' a.
A Repository for Multirelational Dynamic Networks

Nowadays, WWW contains a number of social media sites, which are growing rapidly. One of the main features of social media sites is to allow to its users creation and modification of contents of the site utilizing the offered WWW interfaces. Such contents are referred to as user generated contents and their type varies from site to site. Social media sites can be modeled as constantly evolving multirelational directed graphs. In this paper we discuss persistent data structures for such graphs, and present and analyze queries performed against the structures. We also estimate the space requirements of the proposed data structures, and compare them with the naive "store each complete snapshot of the graph separately". We also investigate query performance against our data structure. We present analytical estimation results, simulation results, and discuss its performance when it is used to store entire contents of Live journal.
Error-Correcting Isomorphisms of Attributed Relational Graphs for Pattern Analysis

The pattern deformational model proposed by Tsai and Fu [11] is extended so that numerical attributes and probability or density distributions can be introduced into primitives and relations in a nonhierarchical relational graph. Conventional graph isomorphisms are then generalized to include error-correcting capability for matching deformed patterns represented by such attributed relational graphs. An ordered-search algorithm is proposed for determining error-correcting isomorphisms. Finally, a pattern classification approach using graph isomorphisms is described, which can be considered as a combination of structural and statistical techniques.
Malingering Dissociative Identity Disorder: Objective and Projective Assessment

Verification of dissociative identity disorder presents challenges given the complex nature of the illness. This study addressed the concern that this disorder can be successfully malingered on objective and projective psychological tests. 50 undergraduate women were assigned to a Malingering or a Control condition, then completed the Rorschach Inkblot Test and the Dissociative Experiences Scale II. The Malingering group were asked to simulate dissociative identity disorder; controls received instructions to answer all materials honestly. Analysis indicated that malingerers were significantly more likely to endorse dissociative experiences on the Dissociative Experiences Scale II in the range common to patients with diagnosed dissociative identity disorder. However, on the Rorschach there were no significant differences between the two groups. Results suggest that the assessment of dissociative identity disorder requires a multifaceted approach with both objective and projective assessment tools. Research is needed to assess these issues in clinical populations.
Psychological stress alters the ultrastructure and increases IL-1β and TNF-α in mandibular condylar cartilage

Psychological factors can be correlated with temporomandibular disorders (TMDs), but the mechanisms are unknown. In the present study, we examined the microstructural changes and expression of proinflammatory cytokines in mandibular condylar cartilage of the temporomandibular joint (TMJ) in a psychological stress animal model. Male Sprague-Dawley rats (8 weeks old, 210 ± 10 g) were randomly divided into 3 groups: psychological stress (PS, N = 48), foot shock (FS, N = 24), and control (N = 48). After inducing psychological stress using a communication box with the FS rats for 1, 3, or 5 weeks, PS rats were sacrificed and compared to their matched control littermates, which received no stress and were killed at the same times as the PS rats. Body and adrenal gland weight were measured and corticosterone and adrenocorticotropic hormone levels were determined by radioimmunoassay. After hematoxylin-eosin staining for histological observation, the ultrastructure of the TMJ was examined by scanning electron microscopy. Transcription and protein levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were evaluated by ELISA and semi-quantitative RT-PCR. The PS group showed a significantly higher adrenal gland weight after 3 weeks of stress and higher hormone levels at weeks 1, 3, and 5. Histopathological changes and thinning cartilage were apparent at weeks 3 and 5. In the PS group, TNF-α increased at 1, 3, and 5 weeks and IL-1β increased significantly after 1 and 3 weeks of stress, and then decreased to normal levels by 5 weeks. Psychological stress increased plasma hormone levels and RT-PCR indicated increased IL-1β and TNF-α expression in the TMJ in a time-dependent manner. These results suggest that cytokine up-regulation was accompanied by stress-induced cartilage degeneration in the mandibular condyle. The proinflammatory cytokines play a potential role in initiating the cartilage destruction that eventually leads to the TMDs.
The contribution of educational research to teachers’ professional learning: philosophical understandings

In this paper, we argue from principle that teacher education must enable a positive relationship between educational research and teaching knowledge and practice. We discuss two popular conceptions of good teaching, which conceive of the teacher as craft worker and as executive technician, and suggest that, while each of these aspects of knowing reflects something of the qualities that good teachers need, any one on its own is insufficient. In contrast to such mono-dimensional conceptions, a research-based textured notion of professional judgement encompasses a complementary and mutually enriching relationship between different aspects of professional knowledge and practice. We identify three interconnected and complementary aspects of teachers’ professional knowledge: situated understanding; technical knowledge; and critical reflection. Accordingly, teaching as professional endeavour demands of teachers practical know-how, conceptual understandings of education, teaching and learning, and the ability to interpret and form critical judgements on existing knowledge and its relevance to their particular situation. We conclude that in principle research can both enrich and be enriched by teachers’ professional knowledge and practice but that to build this relationship in a holistic way into teacher education programmes and partnership models presents considerable practical challenges.
Staged analysis: From evocative to comparative visualizations of Urban mobility

In this paper we examine the concept of staged analysis through a case study on visualizing urban mobility exhibited in a public gallery space. Recently, many cities introduced bike-sharing in order to promote cycling among locals and visitors. We explore how citizens can be guided from evocative impressions of bicycling flows to comparative analysis of three bike-sharing systems. The main aim for visualizations in exhibition contexts is to encourage a shift from temporary interest to deeper insight into a complex phenomenon. To pursue this ambition we introduce cf. city flows, a comparative visualization environment of urban bike mobility designed to help citizens casually analyze three bike-sharing systems in the context of a public exhibition space. Multiple large screens show the space of flows in bike-sharing for three selected world cities: Berlin, London, and New York. Bike journeys are represented in three geospatial visualizations designed to be progressively more analytical, from animated trails to small-multiple glyphs. In this paper, we describe our design concept and process, the exhibition setup, and discuss some of the insights visitors gained while interacting with the visualizations.
Effect of Whole-Body Electromyostimulation on Energy Expenditure During Exercise

Kemmler, W, von Stengel, S, Schwarz, J, and Mayhew, JL. Effect of whole-body electromyostimulation on energy expenditure during exercise. J Strength Cond Res 26(1): 240–245, 2012—The application of whole-body electromyostimulation (WB-EMS) in the area of fat reduction and body shaping has become more popular recently. Indeed, some studies prove positive outcomes concerning parameters related to body composition. However, there are conflicting data as to whether EMS relevantly impacts energy expenditure (EE) during or after application. Thus, the main purpose of the study was to determine the acute effect of WB-EMS on EE. Nineteen moderately trained men (26.4 ± 4.3 years) were randomly assigned to a typically used low-intensity resistance exercise protocol (16 minutes) with (85 Hz) and without WB-EMS. Using a crossover design, the same subjects performed both tests after completely recovering within 7 days. Energy expenditure as the primary endpoint of this study was determined by indirect calorimetry. The EE during low-intensity resistance exercise with adjuvant WB-EMS was significantly higher (p = 0.008) than that during the control condition (412 ± 60 vs. 352 ± 70 kcal; effect size; d = 0.92). This study clearly demonstrates the additive effect of WB-EMS on EE in moderately trained subjects during low-intensity resistance exercise training. Although this effect was statistically significant, the fast and significant reductions of body fat observed in recent studies suggest that the effect of WB-EMS on EE may still be underestimated by indirect calorimetry because of the inability of indirect calorimetry to accurately assess EE during “above–steady state conditions. ” Although from a statistically point of view WB-EMS clearly impacts EE, the relatively small effect did not suggest a broad application of this device in this area. However, taking other positive outcomes of this technology into account, WB-EMS may be a time-saving option at least for subjects unwilling or unable to exercise conventionally.
