Tetrakis[μ-1,3-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene-κ2 N:N′]trisilver(I) tris(hexafluoridophosphate)

In the title compound, [Ag3(C12H12N2O2)4](PF6)3, one AgI ion, lying on a twofold rotation axis, is coordinated by four N atoms from four 1,3-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted tetrahedral geometry and the other AgI ion is coordinated by two N atoms from two L ligands in a bent arrangement [N—Ag—N = 169.03 (17)°]. Two L ligands adopt a syn conformation, while the other two adopt an anti conformation. They bridge adjacent AgI ions, forming a trinuclear complex. One of the PF6 − anions is half-occupied, with the P atom located on a twofold rotation axis. The PF6 − anions link the complex molecules via Ag⋯F interactions [2.80 (2) and 2.85 (2) Å] into a polymeric chain along [100].

Valores normativos do desempenho motor: Construção de cartas percentílicas baseadas no método LMS de Cole & Green

O proposito principal deste estudo foi construir valores de referencia percentilica para provas de aptidao fisica (AptF), ao mesmo tempo que contrasta, graficamente, os niveis de AptF de criancas e adolescentes vouzelenses com os de outras pesquisas nacionais e internacionais. Foi avaliada uma amostra de 1920 criancas e adolescentes, com idades entre os 7 e os 17 anos em cinco testes motores: dinamometria manual, impulsao horizontal, corrida vaivem, corrida de 50 jardas e corrida/marcha da milha. As cartas percentilicas foram construidas com base no metodo LMS, implementado no software LMSchartmarker Pro versao 2.54. Os resultados sugerem forte variabilidade interindividual no desempenho motor. Em todas as provas, os rapazes apresentaram valores medios mais elevados do que as raparigas, sobretudo durante o periodo circum-pubertario. Na comparacao do percentil 50 da prova de forca manual, criancas e jovens vouzelenses tiveram desempenho similar aos de outros estudos, enquanto nas provas de impulsao horizontal, corrida vaivem e de 50 jardas constatou-se superioridade da amostra norte-americana. Na corrida/marcha da milha, a performance dos vouzelenses foi superior as amostras acoriana e americana.
Dialogical Sequence Analysis and the Zone of Proximal Development as Conceptual Enhancements to the Assimilation Model: The Case of Jan Revisited

The assimilation model has proposed a set of developmental stages through which a client's problematic experiences pass in successful psychotherapy. We present 2 conceptual additions to the model. First, we examine the client's problematic experiences using dialogical sequence analysis, an intensive method for studying the moment-to-moment process. Second, we extend the developmental stages to describe the intersubjective exchange between client and therapist by introducing Vygotsky's concept of the zone of proximal development. We illustrate the application of the new conceptual tools by presenting 3 excerpts from the 1st session with Jan, a 42-year-old woman whose therapy has been studied previously. Our analysis suggested that, during the 1st session, Jan's problems reached higher developmental stages in the joint exchange with her therapist (i.e., in the zone of proximal development) than in her internal assimilation.
Electron Acceleration at Pulsar Wind Termination Shocks

We study the acceleration of electrons and positrons at an electromagnetically modified, ultrarelativistic shock in the context of pulsar wind nebulae. We simulate the outflow produced by an obliquely rotating pulsar in proximity of its termination shock with a two-fluid code that uses a magnetic shear wave to mimic the properties of the wind. We integrate electron trajectories in the test-particle limit in the resulting background electromagnetic fields to analyze the injection mechanism. We find that the shock-precursor structure energizes and reflects a sizable fraction of particles, which becomes available for further acceleration. We investigate the subsequent first-order Fermi process sustained by small-scale magnetic fluctuations with a Monte Carlo code. We find that the acceleration proceeds in two distinct regimes: when the gyroradius exceeds the wavelength of the shear λ, the process is remarkably similar to first-order Fermi acceleration at relativistic, parallel shocks. This regime corresponds to a low-density wind that allows the propagation of superluminal waves. When which corresponds to the scenario of driven reconnection, the spectrum is softer.
Implantation and Recovery of Long-Term Archival Transceivers in a Migratory Shark with High Site Fidelity

We developed a long-term tagging method that can be used to understand species assemblages and social groupings associated with large marine fishes such as the Sand Tiger shark Carcharias taurus. We deployed internally implanted archival VEMCO Mobile Transceivers (VMTs; VEMCO Ltd. Nova Scotia, Canada) in 20 adult Sand Tigers, of which two tags were successfully recovered (10%). The recovered VMTs recorded 29,646 and 44,210 detections of telemetered animals respectively. To our knowledge, this is the first study to demonstrate a method for long-term (~ 1 year) archival acoustic transceiver tag implantation, retention, and recovery in a highly migratory marine fish. Results show low presumed mortality (n = 1, 5%), high VMT retention, and that non-lethal recovery after almost a year at liberty can be achieved for archival acoustic transceivers. This method can be applied to study the social interactions and behavioral ecology of large marine fishes.
Interaction of the putative tyrosine recombinases RipX (UU145), XerC (UU222), and CodV (UU529) of Ureaplasma parvum serovar 3 with specific DNA

Phase variation of two loci (‘mba locus’ and ‘UU172 phase-variable element’) in Ureaplasma parvum serovar 3 has been suggested as result of site-specific DNA inversion occurring at short inverted repeats. Three potential tyrosine recombinases (RipX, XerC, and CodV encoded by the genes UU145, UU222, and UU529) have been annotated in the genome of U. parvum serovar 3, which could be mediators in the proposed recombination event. We document that only orthologs of the gene xerC are present in all strains that show phase variation in the two loci. We demonstrate in vitro binding of recombinant maltose-binding protein fusions of XerC to the inverted repeats of the phase-variable loci, of RipX to a direct repeat that flanks a 20-kbp region, which has been proposed as putative pathogenicity island, and of CodV to a putative dif site. Co-transformation of the model organism Mycoplasma pneumoniae M129 with both the ‘mba locus’ and the recombinase gene xerC behind an active promoter region resulted in DNA inversion in the ‘mba locus’. Results suggest that XerC of U. parvum serovar 3 is a mediator in the proposed DNA inversion event of the two phase-variable loci.
A Compact and Integrated Multifunctional Power Electronic Interface for Plug-in Electric Vehicles

The basic power electronic interfaces rendering volume and weight of electric and plug-in hybrid electric vehicles are an inverter, an on-board charger, and a bidirectional dc/dc converter. This paper proposes an innovative integrated bidirectional converter with a single-stage on-board charger to reduce the number of switches, size, and weight of the power electronic interfaces. The analyses show that 266 cm 3 and 1.1 kg can be saved due to the elimination of the inductor core used for power factor correction in charging mode, in addition to the reduction achieved through removal of inductor winding, power switches, diodes, and additional heat sink of the conventional structures. A proof-of-concept prototype with power limits of 8.4 kW in charging and 20 kW in propulsion modes has been designed and validated at various power levels. The peak efficiencies for propulsion and regenerative braking operations are measured as 96.6% and 94.1%, respectively. The power factor is recorded as 0.995 at 1.8 kW charging power, where crest factor and peak efficiency are recorded as 1.49 and 91.6%, respectively.
A vocabulary-size test of controlled productive ability

It is important in the design of the vocabulary component of a teaching program that teachers are able to discover the state of their learners’ vocabulary knowledge. It is also important that researchers can draw on a variety of vocabulary measures to investigate the nature of vocabulary growth. This study focuses on a controlled production measure of vocabulary consisting of items from five frequency levels, and using a completion item type like the following. The garden was full of fra flowers. The controlled-production vocabulary-levels test was found to be reliable, valid (in that the levels distinguished between different proficiency groups) and practical. There was a satisfactory degree of equivalence between two equivalent forms of the test.
Stereotypes and Politics: Reflections on Personas

Using personas in requirement analysis and software development is becoming more and more common. The potential and problems with this method of user representation are discussed controversially in HCI research. While personas might help focus on the audience, prioritize, challenge assumptions, and prevent self-referential design, the success of the method depends on how and on what basis the persona descriptions are developed, perceived, and employed. Personas run the risk of reinscribing existing stereotypes and following more of an I-methodological than a user-centered approach. This paper gives an overview of the academic discourse regarding benefits and downfalls of the persona method. A semi-structured interview study researched how usability experts perceive and navigate the controversies of this discourse. The qualitative analysis showed that conflicting paradigms are embedded in the legitimization practices of HCI in the political realities of computer science and corporate settings leading to contradictions and compromises.
Extracting Relation Descriptors with Conditional Random Fields

In this paper we study a novel relation extraction problem where a general relation type is defined but relation extraction involves extracting specific relation descriptors from text. This new task can be treated as a sequence labeling problem. Although linear-chain conditional random fields (CRFs) can be used to solve this problem, we modify this baseline solution in order to better fit our task. We propose two modifications to linear-chain CRFs, namely, reducing the space of possible label sequences and introducing long-range features. Both modifications are based on some special properties of our task. Using two data sets we have annotated, we evaluate our methods and find that both modifications to linear-chain CRFs can significantly improve the performance for our task.
The Independent Effects of Attention and Lead Stimulus Properties on the Acoustic Blink Reflex

The effects of attention to a lead stimulus and of its sensory properties on modulation of the acoustic blink reflex were investigated. Participants performed a reaction time task cued by an acoustic or a visual lead stimulus. In Experiment 1, half the participants were presented with sustained lead stimuli. For the remainder, the lead stimulus was discrete and consisted of two brief presentations that marked the onset and offset of a stimulus-free interval. In Experiment 2, sustained lead stimuli were presented at a low or high intensity. The attentional demands of the task enhanced blink latency and magnitude modulation during acoustic and visual lead stimuli, with blink modulation being largest at a late point during the lead stimulus. Independent of the attentional effects, blink latency and magnitude modulation were larger during sustained than during discrete acoustic lead stimuli, whereas there was no difference for visual lead stimuli. Increases in the intensity of the lead stimulus enhanced blink modulation regardless of lead stimulus modality. Attention to a lead stimulus and the properties of the lead stimulus appear to have independent effects on blink reflex modulation.
End-to-End Java Security Performance Enhancements for Oracle SPARC Servers

In this paper we investigate the performance of cryptographic operations, when used in Java applications. We demonstrate the advantage of using built-in hardware accelerator for cryptographic operations on SPARC servers. In particular, we demonstrate the advantage of hardware cryptographic instructions invoked via AES and SHA intrinsics, implemented in the Java Virtual Machine (JVM), over the more traditional Java Native Interface (JNI) calls. For the purpose of our study, we modified the SPECweb2005 benchmark by adding modern banking requirements, and created a new workload which we call the End-to-End Java Security (EEJS) workload. Using the workload, we compare different Java Cryptographic Service Providers (CSPs) and arrive at the conclusion that hardware cryptography has significant performance advantage for Java applications. With the EEJS workload, we also identify several enhancements applicable to the Java Secure Socket Extension (JSSE).
SDN based Control and Management of WLANs in the 3GPP 5G Network

The exponential growth in mobile broadband usage [1] has catalyzed the need for high data rate communication systems. In this regard, activities for standardizing the next generation mobile broadband system, known as the Fifth Generation(5G) system are underway. The 5G system also enables the integration of Institute of Electrical and Electronic Engineers (IEEE) Wireless Local Area Networks (WLANs) for providing cost-effective broadband connectivity. It is therefore imperative to find solutions for control and management of WLANs, while providing seamless inter-working capabilities with the cellular network. In this paper, we propose a novel Software Defined Networking (SDN) based architecture for efficient control and management of IEEE WLANs while providing a mechanism for smooth integration of WLANs within the 5G system.
A Proposed Method for Establishing Partial Discharge Acceptance Limits on API 541 and 546 Sacrificial Test Coils

Recent revisions to API standards have identified offline partial discharge analysis as an appropriate factory acceptance test (FAT) to evaluate the quality of certain new medium voltage motor and generator stator windings. As a starting point, API 541 recommends a partial discharge (PD) level of 100 pC (pico-Coulombs) for sacrificial stator coils measured with an IEC 60270 compliant instrument. The recommended PD level is subject to discussion between the purchaser and the manufacturer until more data are available. This paper provides PD data from sacrificial coils and stator windings to support discussions on PD acceptance criteria. Three instruments were used for PD tests on resin-rich, press-cured sacrificial coils in laboratory conditions controlled to minimize noise, and in the typical environment of a FAT. These coils were then tested daily for a week, with identical measurement conditions of noise, time of day, operator, and instrument. Also, included are examples of offline PD data from two complete stator windings. The first was a new winding, tested in the factory on two different days. The second was an aged winding tested using the same methods but in different locations. Instrument selection, testing location, elapsed time between measurements and insulation system construction can influence offline PD measurements. The current evidence suggests that statistical distributions drawn from similar test conditions are more applicable than specific PD limits.
Occupational Meanings of Food Preparation for Goan Canadian Women

Food-related occupations connect people with bodies, traditions, rituals, community, family, and caring. Food holds sensate memories and may vividly evoke the past. For those who live in a diaspora, sharing an ethnic heritage yet displaced from a homeland, food may comprise a major means of cultural transmission. This qualitative study explores the meanings of food and food-related occupations for 13 Goan women in Toronto, Canada. Catholic Goans, an ethnic group borne of Portuguese colonization of an area in what is now Western India, have few unique markers of ethnic distinction from other Indians. In this context, Goan cuisine becomes a powerful boundary marker, and food-related occupations carry a particular salience in cultural maintenance. Skill in culinary occupations may then be experienced as a form of power or ‘currency’ for women, because they are able to produce a highly significant symbol of culture.
Peeresses, Parliament and prejudice: the admission of women to the House of Lords, 1918–1963

SUMMARY In this article Duncan Sutherland examines a subject that has been almost entirely ignored by British constitutional historians, the admission of women to the House of Lords. There had always been hereditary peeresses, their status as peeresses did not confer the right to sit in the House of Lords. The womens' suffrage movement had ignored the issue, and attempts to use the right of women to sit as MPs in the Acts of 1918 and 1919 to entitle peeresses to sit in the Lords failed. So did subsequent attempts to have them admitted by legislation: the political parties did not see it as an important issue, and it was inextricably mixed up with the wider question of general reform of the House of Lords. Only after the creation of life peerages, after 1958, were women admitted to the House, and even then the hereditary peeresses had to wait until 1963 for admission. The article concludes by considering the kinds of arguments advanced for continuing the exclusion of women. The long delay, in light of the feebleness and inconsistencies of the case for continuing the exclusion of women, seems to indicate the low importance that the political Establishment attached to the issue.
Russian in Latvia: an outlook for bilingualism in a post-Soviet transitional society

Abstract What makes people, in shifting power positions of a post-independence period, plan on disusing an already known L2 or learn a new L2? What are the reasons for such shifts and what outcomes can, therefore, be predicted for the future of societal bilingualism surviving alongside ongoing efforts at monolingual unification in a newly independent nationstate? In my paper, I examine Russian in Latvia, and also societal bilingualism in the country in terms of L1/L2 users, language-minority education, competitiveness and language policy, couched in a discussion of various theoretical perspectives on language and nationalism. The Baltic republic, which re-established its independence from the Soviet Union in 1991, has retained a legacy of not only a substantial proportion of the Russian-speaking population who are now learning Latvian as their L2, but also even a slightly greater number of Russian-speaking non-Russians (i.e. Latvians and other ethnic minorities) who had an obligation to acquire and use Russian as their L2 during the Soviet era.
The espn Assemblage: The Political and Cultural Economy of Late Sports Capitalism

Drawing on the perspectives of cultural studies and the political and cultural economy of late capitalism, this paper offers an interpretive framework for engaging the <small class="caps">espn </small> assemblage as expressed in and through the complexities of the contemporary sports spectacle. First, the paper focuses on <small class="caps">espn </small>’s brand of neoliberal orthodoxy as a means of dominating the sports-media marketplace through a political ideology arrayed in programming, texts, and consumer services. Second, it considers <small class="caps">espn </small>’s capitalization and commodification in the broadest sense by identifying the centrality of culture to the workings of late capitalism. Third, the paper considers how <small class="caps">espn </small> maintains a place of dominance by encouraging people to consume culture within an exchange system that confers power and status. Finally, the paper reflects on the changing landscape of corporate sports media and <small class="caps">espn </small>’s place within that landscape.
Integrator Leakage for Limit Cycle Suppression in Servo Mechanisms With Stiction

This paper reports quantitative answers to two questions regarding the limit cycle behavior arising from the servo mechanisms with stiction under the positional PID (Proportional-Integral-Derivative) control. The first question is, how large the magnitude of the limit cycle is for a given value of stiction force. The second one is how we should modify the PID controller to avoid this limit cycle with minimal degradation in the serve performance. The main approach is based on understanding key algebraic properties of the state trajectory. As a result, a simple bisection algorithm has been devised to compute the exact magnitude of the periodic solution for a given value of stiction. A direct extension of this algorithm enables us to find the minimum value of the integrator leakage to avoid the limit cycle. A numerical example demonstrates the main results.Copyright © 2011 by ASME
Towards a new approach for real time face detection and normalization

Nowadays, face recognition algorithms, proposed in the literature, reached a correct performance level when the acquisitions conditions for the tested images are controlled (variability of the environment, illumination, poses, expressions and also the number of images in the database to identify people). These performances fall when these conditions are degraded. The controlled conditions of acquisition correspond to a good balance of illumination, as well as a high-resolution, a good pose of the face and a maximum sharpness of the face image. Although several methods have been proposed to resolve the problem of illumination variation, the problem of rotation and occlusion still an obstacle. In this paper, we propose a new method for face detection and normalization which consists to choose the best pose and the point of view of the detected face. This normalization conducts us to select the normalized images to be used as an input in the recognition process, in order to improve its performance. This approach was implemented and tested on a public database. The preliminary results seem very promising.
Stress and Coping in Police Officers

Police officers encounter numerous stressors as part of their professional duties. Dissociation, the splitting off from awareness thoughts, feelings, or memories of stressful events, is one psychological defense associated with avoidance of emotionally painful material. In this study, dissociation, stressful or traumatic experiences, and psychological adjustment were measured in a sample of police officers. Stress was not directly associated with psychological adjustment, but increased stress did predict increased dissociation. Increased dissociation was associated with poorer adjustment. These data suggest that it is not the stressors themselves but officers' manner of coping with them that determine psychological adjustment.
