The dynamics of ensemble: the case for flamenco

We provide behavioural and quantitative analyses of coordination and synchronization in ensemble performance, using flamenco as a case study. The concept of ensemble is introduced and developed with the aid of connected network models, then applied to the flamenco ensemble. Flamenco performance is described in terms of ensemble interaction, including both the types of rhythmical accompaniment used by the individual classes of performer participating in the ensemble and the main sociocultural factors governing control of rhythm and cuing changes. These factors involve hierarchies relating to the degree to which each performer commands audience attention (focus) and the status of ensemble members within the company. We describe an observational approach to ensemble coordination with an event-based video analysis of a four-member ensemble performing a flamenco piece and a correlation-based motion analysis of two-person performance of simple rhythm.
Influence of sex hormonal status on alcohol-induced oxidative injury in male and female rat liver.

BACKGROUND Oxidative stress contributes to the development of liver injury after chronic alcohol intake. Women exhibit greater sensitivity to alcohol-induced liver disease than do men. The aim of the study was to determine the relationship between the sex hormone status of male and female rats and the degree of alcohol-induced oxidative stress in the liver. METHODS Male and female rats were pair-fed a liquid diet that contained 36% of their total daily calories as ethanol (EtOH group) or maltose (control group). Blood and liver samples were collected at the end of 8 weeks of diet. RESULTS Male EtOH rats experienced a reduction in plasma testosterone (T) and an increase in estradiol (E2) levels, with an increase in their calculated E2/T ratio with respect to their controls. Malonaldehyde (MDA) levels, an index of lipid peroxidation, and protein carbonyl content, an index of protein oxidation, in the liver were greater among the EtOH groups in females than in males. In males, an inverse correlation was found between hepatic MDA and circulating T levels, and a direct correlation was disclosed between MDA and estradiol levels. In addition, the hepatic histopathological score correlated inversely with the plasma T levels and directly with the calculated E2/T ratio, an index of feminization. CONCLUSIONS Alcohol-induced oxidative injury, which contributes to hepatic injury in both male and female rats, is enhanced in females compared with males. A role for plasma T levels in protecting male rat liver from ethanol-induced oxidative injury can be hypothesized.
Composition Validation and Subjectivity in GenVoca Generators

GenVoca generators synthesize software systems by composing components from reuse libraries. GenVoca components are designed to export and import standardized interfaces, and thus be plug-compatible, interchangeable, and interoperable with other components. We examine two different but important issues in software system synthesis. First, not all syntactically correct compositions of components are semantically correct. We present simple, efficient, and domain-independent algorithms for validating compositions of GenVoca components. Second, components that export and import immutable interfaces are too restrictive for software system synthesis. We show that the interfaces and bodies of GenVoca components are subjective, i.e., they mutate and enlarge upon instantiation. This mutability enables software systems with customized interfaces to be composed from components with "standardized" interfaces.
Synaptic connections between eyelet photoreceptors and pigment dispersing factor‐immunoreactive neurons of the blowfly Protophormia terraenovae

Studies using various mutants of Drosophila melanogaster bearing defects in their visual system, including those of the retinal and extraretinal photoreceptor systems, have indicated that the extraretinal photoreceptor known as the Hofbauer‐Buchner (H‐B) eyelet plays an active, if subsidiary, role in the entrainment of circadian rhythms. In the present study, in the context of unraveling the function of extraretinal photoreception on circadian rhythms and photoperiodic responses, we searched for extraretinal photoreceptors in the blowfly, Protophormia terraenovae, and found that this fly has a homolog of the H‐B eyelet. In addition, we show morphologically direct synaptic connections between the eyelet of P. terraenovae (called here Pt‐eyelet, after the species' name) and pigment‐dispersing factor (PDF)‐immunoreactive neurons, which are putative circadian pacemaker neurons, by immunogold electron microscopy combined with intracellular dye injection. The Pt‐eyelet was found to reside in the middle of the posterior surface of the optic lobe between the retina and the lamina, as does the H‐B eyelet. This extraretinal photoreceptor was composed of at least four photoreceptor cells equipped with well‐organized microvillar rhabdomeres. Rhodopsin 6‐like immunoreactivity and also the response to light stimuli clearly showed the Pt‐eyelet to be functional. The Pt‐eyelet terminals in the accessory medulla exhibited synaptic bouton‐like appearances and formed divergent multiple‐contact output synapses. Synaptic contacts from the Pt‐eyelet terminal to the PDF‐immunoreactive neurons were identified by the presence of presynaptic ribbons and accumulated synaptic vesicles. Their possible function is discussed in relation to previous studies on circadian rhythm and photoperiodic response of P. terraenovae. J. Comp. Neurol. 494:331–344, 2006. © 2005 Wiley‐Liss, Inc.
Ethnic Differences in Glycemic Markers in Patients With Type 2 Diabetes

OBJECTIVE Recent studies have reported hemoglobin A1c (HbA1c) differences across ethnic groups that could limit its use in clinical practice. The authors of the A1C-Derived Average Glucose study have advocated to report HbA1c in estimated average glucose (AG) equivalents. The aim of this study was to assess the relationships between HbA1c and the mean of three 7-point self-monitored blood glucose (BG) profiles, and to assess whether estimated AG is an accurate measure of glycemia in different ethnic groups. RESEARCH DESIGN AND METHODS We evaluated 1,879 participants with type 2 diabetes in the DURABLE trial who were 30 to 80 years of age, from 11 countries, and, according to self-reported ethnic origin, were Caucasian, of African descent (black), Asian, or Hispanic. We performed logistic regression of the relationship between the mean self-monitored BG and HbA1c, and estimated AG, according to ethnic background. RESULTS Baseline mean (SD) HbA1c was 9.0% (1.3) (75 [SD, 14] mmol/mol), and mean self-monitored BG was 12.1 mmol/L (3.1) (217 [SD, 55] mg/dL). In the clinically relevant HbA1c range of 7.0–9.0% (53–75 mmol/mol), non-Caucasian ethnic groups had 0.2–0.5% (2–6 mmol/mol) higher HbA1c compared with Caucasians for a given BG level. At the mean self-monitored BG levels ≤11.6 mmol/L, estimated AG overestimated the actual average BG; at levels >11.6 mmol/L, estimated AG underestimated the actual BG levels. CONCLUSIONS For a given degree of glycemia, HbA1c levels vary among different ethnic groups. Ethnicity needs to be taken into account when using HbA1c to assess glycemic control or to set glycemic targets. Estimated AG is not a reliable marker for mean glycemia and therefore is of limited clinical value.
Managerial Level and Subunit Function as Determinants of Networking Behavior in Organizations

This article describes a field study conducted to test a conceptual model on situational determinants of networking behavior. The findings indicated support for a new measure of internal and external networking behavior. Consistent with our model, external networking was affected by managerial function and level, but internal networking was affected only by managerial level. Dependencies partially mediated the effects of managerial function and level on networking behaviors. The amount of dependency on different types of network members also varied by level and function. However, the reasons given by managers for dependency on key network members were similar for internal and external networks. Rate of advancement for managers was predicted weakly by their internal and external networking.
SOME PERSONAL REMARKS ON THE DEVELOPMENT OF MODEL THEORY FOR USE IN ANALYSIS AND GEOMETRY

I’m writing these remarks on the occasion of the AIM workshop on model theory for metric structures that Itäı Ben-Yaacov and I are organizing for the week Sept. 18–22, 2006. This is the first research meeting in which the new continuous version of first-order logic takes center stage for discussions about making model theory an effective tool in analysis, probability, and geometry. These remarks give my personal sense of how this effort began and how, rather recently, continuous logic came to be seen by many of us as the best available logic for the purpose.
Neural Representation of Task Difficulty and Decision Making during Perceptual Categorization: A Timing Diagram

When does the brain know that a decision is difficult to make? How does decision difficulty affect the allocation of neural resources and timing of constituent cortical processing? Here, we use single-trial analysis of electroencephalography (EEG) to identify neural correlates of decision difficulty and relate these to neural correlates of decision accuracy. Using a cued paradigm, we show that we can identify a component in the EEG that reflects the inherent task difficulty and not simply a correlation with the stimulus. We find that this decision difficulty component arises ≈220 ms after stimulus presentation, between two EEG components that are predictive of decision accuracy [an “early” (170 ms) and a “late” (≈300 ms) component]. We use these results to develop a timing diagram for perceptual decision making and relate the component activities to parameters of a diffusion model for decision making.
How Personality Traits Mediate the Relationship Between Flow Experience and Job Performance

This study shows the importance of positive work-related experience, positive mood, and health psychology by examining their relationships. Thus, the study builds and tests an integrated model to investigate the relationships among flow experience, personality traits, and job performance. This article explores these relationships using structural equation model (SEM) with data from 326 primary school teachers in Taiwan. The findings show that extraversion and conscientiousness partially mediate the relationship between flow experience and job performance. Results of moderated-SEM analyses generally support the hypotheses. The article concludes with theoretical and managerial implications of the research findings.
Support vector machines with a reject option

This paper studies $\ell_1$ regularization with high-dimensional features for support vector machines with a built-in reject option (meaning that the decision of classifying an observation can be withheld at a cost lower than that of misclassification). The procedure can be conveniently implemented as a linear program and computed using standard software. We prove that the minimizer of the penalized population risk favors sparse solutions and show that the behavior of the empirical risk minimizer mimics that of the population risk minimizer. We also introduce a notion of classification complexity and prove that our minimizers adapt to the unknown complexity. Using a novel oracle inequality for the excess risk, we identify situations where fast rates of convergence occur.
Careership: a sociological theory of career decision making

Abstract In the current discourse on the transition from school to work, career decision‐making has a pivotal but paradoxical position. Sociological literature emphasises the dominance of socially‐structured pathways, whilst policy‐making operates on assumptions of individual freedom to choose. In this paper we draw on the work of Pierre Bourdieu to present a new model of career decision‐making, given the shorthand title of ‘careership’. There are three completely integrated dimensions to the model. These are (i) pragmatically rational decision‐making, located in the habitus of the person making the decision; (ii) the interactions with others in the (youth training) field, related to the unequal resources different ‘players’ possess; and (iii) the location of decisions within the partly unpredictable pattern of turning‐points and routines that make up the life course. This model avoids the twin pitfalls of implicit social determinism or of seeing (young) people as completely free agents.
Comparison of low-molecular-weight heparin and warfarin for the secondary prevention of venous thromboembolism in patients with cancer: a randomized controlled study.

BACKGROUND The use of warfarin sodium for treating venous thromboembolism in patients with cancer is associated with a significant risk of recurrence and bleeding. The use of low-molecular-weight heparin sodium for secondary prevention of venous thromboembolism in cancer patients may reduce the complication rate. OBJECTIVE To determine whether a fixed dose of subcutaneous low-molecular-weight heparin is superior to oral warfarin for the secondary prophylaxis of venous thromboembolism in patients with cancer and venous thromboembolism. METHODS In a randomized, open-label multicenter trial performed between April 1995 and March 1999, we compared subcutaneous enoxaparin sodium (1.5 mg/kg once a day) with warfarin given for 3 months in 146 patients with venous thromboembolism and cancer. MAIN OUTCOME MEASURE A combined outcome event defined as major bleeding or recurrent venous thromboembolism within 3 months. RESULTS Of the 71 evaluable patients assigned to receive warfarin, 15 (21.1%; 95% confidence interval [CI], 12.3%-32.4%) experienced one major outcome event compared with 7 (10.5%) of the 67 evaluable patients assigned to receive enoxaparin (95% CI, 4.3%-20.3%; P =.09). There were 6 deaths owing to hemorrhage in the warfarin group compared with none in the enoxaparin group. In the warfarin group, 17 patients (22.7%) died (95% CI, 13.8%-33.8%) compared with 8 (11.3%) in the enoxaparin group (95% CI, 5.0%-21.0%; P =.07). No difference was observed regarding the progression of the underlying cancer or cancer-related death. CONCLUSIONS These results confirm that warfarin is associated with a high bleeding rate in patients with venous thromboembolism and cancer. Prolonged treatment with low-molecular-weight heparin may be as effective as oral anticoagulants and may be safer in these cancer patients.
How the concept of biochemical response influenced the management of primary biliary cholangitis over time.

BACKGROUND Criteria assessing biochemical response to ursodeoxycholic acid (UDCA) are established risk stratification tools in primary biliary cholangitis (PBC). We aimed to evaluate to what extent liver tests influenced patient management during a three decade period, and whether this changed over time. METHODS 851 Dutch PBC patients diagnosed between 1988 and 2012 were reviewed to assess patient management in relation to liver test results during UDCA treatment. To do so, biochemical response at one year was analysed retrospectively according to Paris-1 criteria. RESULTS Response was assessable for 687/851 (81%) patients; 157/687 non-responders. During a follow-up of 8.8 years (IQR 4.8-13.9), 141 died and 30 underwent liver transplantation. Transplant-free survival of non-responders (60%) was significantly worse compared with responders (87%) (p < 0.0001). Management was modified in 46/157 (29%) non-responders. The most frequent change observed, noted in 26/46 patients, was an increase in UDCA dosage. Subsequently, 9/26 (35%) non-responders became responders within the next two years. Steroid treatment was started in one patient; 19 patients were referred to a tertiary centre. No trend towards more frequent changes in management over time was observed (p = 0.10). CONCLUSION Changes in medical management occurred in a minority of non-responders. This can largely be explained by the lack of accepted response criteria and of established second-line treatments for PBC. Nevertheless, the observation that response-guided management did not increase over time suggests that awareness of the concept of biochemical response requires further attention,particularly since new treatment options for PBC will soon become available.
Uncovering Intrinsic Modular Organization of Spontaneous Brain Activity in Humans

The characterization of topological architecture of complex brain networks is one of the most challenging issues in neuroscience. Slow (<0.1 Hz), spontaneous fluctuations of the blood oxygen level dependent (BOLD) signal in functional magnetic resonance imaging are thought to be potentially important for the reflection of spontaneous neuronal activity. Many studies have shown that these fluctuations are highly coherent within anatomically or functionally linked areas of the brain. However, the underlying topological mechanisms responsible for these coherent intrinsic or spontaneous fluctuations are still poorly understood. Here, we apply modern network analysis techniques to investigate how spontaneous neuronal activities in the human brain derived from the resting-state BOLD signals are topologically organized at both the temporal and spatial scales. We first show that the spontaneous brain functional networks have an intrinsically cohesive modular structure in which the connections between regions are much denser within modules than between them. These identified modules are found to be closely associated with several well known functionally interconnected subsystems such as the somatosensory/motor, auditory, attention, visual, subcortical, and the “default” system. Specifically, we demonstrate that the module-specific topological features can not be captured by means of computing the corresponding global network parameters, suggesting a unique organization within each module. Finally, we identify several pivotal network connectors and paths (predominantly associated with the association and limbic/paralimbic cortex regions) that are vital for the global coordination of information flow over the whole network, and we find that their lesions (deletions) critically affect the stability and robustness of the brain functional system. Together, our results demonstrate the highly organized modular architecture and associated topological properties in the temporal and spatial brain functional networks of the human brain that underlie spontaneous neuronal dynamics, which provides important implications for our understanding of how intrinsically coherent spontaneous brain activity has evolved into an optimal neuronal architecture to support global computation and information integration in the absence of specific stimuli or behaviors.
Increased tissue factor pathway inhibitor activity is associated with myocardial infarction in young women: results from the RATIO study

Summary. Background: The tissue factor pathway inhibitor (TFPI)/protein S anticoagulant system is a potent inhibitor of blood coagulation. TFPI and protein S are major determinants of thrombin generation (TG) tests determined at low tissue factor (TF) and at high TF concentrations in the presence of activated protein C (APC). Both TFPI and protein S protect against venous thrombosis, but the importance of the TFPI/protein S system in arterial thrombosis remains unclear. Objectives: To investigate the influence of the TFPI/protein S anticoagulant system on the risk of myocardial infarction (MI) in young women. Methods: The RATIO study is a case–control study in women under 50 years of age, including 205 patients and 638 controls. TFPI and protein S were quantified using ELISA. The TFPI/protein S activity (nTFPIr) and the APC sensitivity ratio (nAPCsr) were determined using TG tests. Odds ratios (ORs) adjusted for putative confounders and corresponding 95% confidence intervals (95% CI) were determined. Results: Women with MI had higher TFPI levels than controls (135.9 ± 40% vs. 124.2 ± 41%), resulting in increased TFPI/protein S activities and increased APC sensitivity. Furthermore, an increased TFPI activity was associated with MI [nTFPIr: adjusted OR Q1 vs. Q4 = 2.1 (95%CI 1.1–4.1)]. Additionally, an increased APC sensitivity was associated with MI [nAPCsr: adjusted OR Q1 vs. Q4 = 1.7 (95% CI 0.9–3.2)] Conclusion: Women with MI had increased TFPI levels compared with controls. Consequently, the TFPI/protein S activity and APC sensitivity are increased in women with MI. Whether this increase in TFPI activity acts as a compensating mechanism for an increased procoagulant state or is a marker of endothelial damage remains to be investigated.
Coupled quasi‐harmonic bases

The use of Laplacian eigenbases has been shown to be fruitful in many computer graphics applications. Today, state‐of‐the‐art approaches to shape analysis, synthesis, and correspondence rely on these natural harmonic bases that allow using classical tools from harmonic analysis on manifolds. However, many applications involving multiple shapes are obstacled by the fact that Laplacian eigenbases computed independently on different shapes are often incompatible with each other. In this paper, we propose the construction of common approximate eigenbases for multiple shapes using approximate joint diagonalization algorithms, taking as input a set of corresponding functions (e.g. indicator functions of stable regions) on the two shapes. We illustrate the benefits of the proposed approach on tasks from shape editing, pose transfer, correspondence, and similarity.
“Potemkin Europeanisation”?

After the EU’s Eastern enlargement of 2004, it became clear that some of the reform in the former candidate countries resembled a Potemkin village: behind a gleaming façade lingered a grimmer reality. Party politics in Central Europe proved to be a case in point. The following article argues that party systems in the region only underwent “Potemkin Europeanisation”—essentially enjoying a “liberal consensus” thanks to a “camouflage effect” of the Europeanisation processes—in 1998–2004. Using case studies of party competition in Poland and Hungary in 1998–2004, it draws broader theoretical conclusions about the persistence of traditional cleavages as organizing principles of party systems in Central Europe, as well as the nature of EU influence on the modus operandi of party politics in candidate countries.
Defining the Effects of Television on the Body Image on the basis of Adolescents’ Opinions

This study aimed to determine the effects of television on the body images of the adolescents at high school. In the study, mixed method was used. Out of 1222 high school students, who completed the “Scale of Satisfaction from Body Parts and Features”, 36 students participated in the study according to their scores from this scale. Qualitative data of the study was collected through semi-structured interviews and the interview data was analyzed descriptively. The results of the study revealed that the majority of the adolescents were satisfied with their bodies, yet the males reported more satisfaction than the females. Furthermore, it was seen that the adolescents emulated the ideal body types and features on television that they wanted to have or they did not have and they sometimes tried to resemble these. Moreover, it was determined that most of the adolescents compared themselves with the ideal body images on TV and they sometimes experienced disappointment and pessimism
