On Membership Categorization: ‘Us’, ‘Them’and‘Doing Violence’ in Political Discourse

This article concerns the attacks on New York and Washington in September 2001. We use Membership Categorization Analysis to establish how the key figures involved in the conflict represented these events and the participants in them. We analyse public addresses made soon after the attacks by the US President George W. Bush, the British Prime Minister Tony Blair and Osama bin Laden of Al Qaeda. Each speaker distinguished ‘us’ from ‘them’ and formulated this distinction so as to justify past violent actions and to prepare grounds for future ones. Bush and Blair both distinguished ‘us’ from ‘them’ in social, political and moral terms, whereas bin Laden did so in religious terms. The categorizations were not done in isolation from each other, but were instead networked. We discuss the relation between membership categorizations, presentations of happenings and violent actions, prior and subsequent and we extend our concept of a ‘dialogical network’.
We are all treated equal, aren't we? — Flow-level performance as a function of flow size

Recent Internet studies have reported on continued traffic growth, changes in applications usage, and a proliferation in the adoption of high-speed access links. Any adverse impact that these observed trends may have on Internet traffic flows can result in sub par performance, which in turn results in unsatisfactory user experience. To study such adverse impacts, we examine in this paper the flow-level performance of popular applications across a range of size-based flow-classes and applications. We use out-of-sequence packets, retransmissions, throughput, and RTTs as key flow performance metrics. Leveraging data sets collected from two complementary network environments, we compare these metrics for popular applications and for the up/downstream directions. We show that irrespective of the direction, flows are severely impacted by the specifics of the network, e.g., DSL or CDN and application behavior. We also find that, in general, this impact differs markedly across the different flow-classes. In particular, contrary to popular belief, the small flows from all applications, which make up the majority of flows, experience significant retransmissions, while the very large flows, although small in number, experience very limited retransmissions. In terms of application-related performance, we observe that especially when compared to HTTP, apart from large flows, P2P flows suffer from continuously high retransmissions and low throughput. As for the root cause of these retransmissions, we identify the access part of the network as the main culprit and not the network core.
Violent Crime and Poisson Regression: A Measure and a Method for Cultivation Analysis

A content analysis of network prime-time television found violent crime over-represented and property crime (burglary) under-represented when compared to crime statistics. These differences were used to predict survey respondents' estimations of crime rates in their community. A significant relationship was found between television exposure and beliefs about crime rates when using a non-linear analytic model. Heavier television viewers were more likely to give higher estimates of murder rates and lower estimates of burglary rates than lighter viewers. These estimation patterns are consistent with televised portrayals and offer support for the cultivation hypothesis.
Implementation of a values training program in physical education and sport: perspectives from teachers, coaches, students, and athletes

Background: Past research has shown that under the right conditions, youth can learn values through physical education and sport (PES). Although some programs have been developed using PES as a means to foster positive development, a limited amount of research has specifically addressed how stakeholders believe this type of material can be promoted. Purpose: The purpose of the current study was to investigate the perspectives of physical education (PE) teachers, sport coaches, PE students, and athletes from a Singaporean school taking part in an instructional program designed to teach values through PES. The study was guided by the four research questions: (a) What were the perceived benefits of the values training program? (b) How did the participants believe that PE students and athletes were able to transfer the values learned in PES to daily applications? (c) What did the participants believe were factors that facilitated and/or hindered the transfer of values? and (d) What do the participants believe could improve future values training programs? Participants: A total of 38 participants (3 PE teachers, 3 sport coaches, 16 PE students, and 16 athletes) were purposefully selected for the present study. The PE teachers and sport coaches ranged in age from 26 to 38 years (M = 32; SD = 2.2), had an average of 7 years of teaching experience (SD = 1.6), and had an average of 2.5 years of coaching experience (SD = 1.2). The PE students and athletes ranged in age from 10 to 12 years (M = 11.7; SD = 0.99). Data collection: Individual in-depth interviews were conducted with PE teachers and sport coaches while focus-group interviews were used for PE students and athletes. Data analysis: The interview transcripts were analyzed using a thematic analysis that was driven by both the data and the research questions. Findings: The results revealed that: (a) PE teachers and sport coaches believed that the training program helped them acquire pedagogical strategies and increased their motivation for teaching values, (b) PE students and athletes believed that they were able to apply some of the values learnt through PES in non-sport settings, (c) purposefully designed activities by PE teachers and sport coaches facilitated the transfer of values, and (d) time constraints were the key challenge that hindered the learning and transfer of values. Conclusion: The current study indicated that for PES to be a context conducive to the learning of values, adult leaders must be trained appropriately, guided by established theories, such as Kolb's theory of experiential learning. PE teachers and sport coaches indicated how they believe that they have benefited from the training program by being better equipped to teach values through PES. Nevertheless, more interventions and more theory-based research are needed to ensure that PES is deliberately designed to provide youth with opportunities to improve as sportspersons and also citizens.
Intelligence, Social Status and Musical Abilities

from correlation Matrix taken from Rainbow (1965). Despite the significant F values obtained in the analysis of variance in respect of musical aptitude, intelligence and socio-economic background, it can be seen that when calculated by correlation methods, the association of the same variables from the same data prove as usual to be "positive but low". Only two possible explanations readily present themselves for this surprising phenomenon. It may be due to either: (a) The interpretive difficulties already discussed associated with use of correlation technique in this context or (b) The intrusion of a third factor located somewhere between intelligence and musical abilities, or both. The remainder of this paper will be devoted to investigation of this question. Part II Further Investigation of the Intelligence/Musical Ability Relationship using Alternative Methods of Data Processing Where a sufficient number of experimental groups are employed in a research design, the use of the analysis of variance may be extended to provide more detailed information of the nature of the data. The effects of successive "treatments", provided that they fall into a natural order along some increasing or decreasing continuum may be further subdivided into trend components by use of orthogonal polynomials. For detailed description of the method and rationale underlying this method, reference should be made to Bruning and Kintz (1968), Winer, B. J. (1962) or Lewis, D. (1960). In simple terms, this procedure tests the approximation of the performances of successive groups to a series of hypothesised rectilinear and curvilinear trends. The "between groups" variance is thereby apportioned to its relative linear, quadratic, cubic, quartic, quintic, etc. trends, and the significance levels of each (expressed by Fas in the main analysis) determined. If the bulk of the between groups variance is taken up by alignment to a linear trend, then a direct relationship between the dependent and independent variables may be assumed. If significant curvilinear trends are revealed, then either a more complex relationship or no direct relationship, between the variables must be presumed. A simple way to evaluate the applicability of this procedure to the intelligence/ musical ability problem would be to reprocess data from a previous investigation where correlation techniques have already been employed. Taylor (1973)* devised two tests of musical abilities (i) a Music Responsiveness Test, and (ii) A Music Discrimination Test for the purposes of his investigation of the musical development of children aged seven to eleven years. The Music Responsiveness Test comprised a battery of three sub-tests, each containing 15 *The authors acknowledge their indebtedness to Dr. Taylor for making the raw scores of his research data available to them.
A produção acadêmica sobre aprendizagem organizacional no Brasil

The recent interest of academia in analyzing processes that result in organizational learning or in describing features of learning organizations has contributed to build a central subject within the international scientific community and the literature addressed to managers and consultants. The present study has attempted to map out the academic production on organizational learning in Brazil. We have analized 43 articles published on main periodicals in the field of Management and annals of two important scientific congresses. Besides mapping this production, the results of this study reveal that some themes, concepts, theoretical frames, references and typologies of research are paramount and prevailing in this field of research. These results may be useful in order to set up a research agenda which tries to solve the main problems related to organizational learning and the scientific gaps in this research area.
A New Low Cost Linear Resolver Converter

A new low cost converter topology is proposed for sinusoidal position encoders. The converter enables determination of the angle from the sine and cosine signals of the encoder. When used with resolvers, the implementation of the present scheme takes advantage of the available excitation signal used to operate the device. This trigonometric reference signal is optimally used to generate an analogue signal equivalent to a digital look-up table (LUT). This enables determination of the mechanical angle without using LUT, A/D, and D/A converters. The scheme is optimized in order to achieve highest possible precision. Beside simplicity of its implementation, the proposed converter offers the advantage of robustness to amplitude fluctuation of the transducer excitation signal. The converter was implemented using ordinary low-cost analog components. The theory of operation, computer simulation, and experimental results are given.
Filling-in along horizontal and vertical meridians.

PURPOSE Filling-in is not homogeneous across the visual field; rather, fading time (FT) varies with eccentricity and polar angle. The reasons for this are unclear. The authors investigated FT along horizontal and vertical meridians in central and peripheral visual fields for luminance-defined targets, comparing Weber contrast sensitivity (CSw). They also compared cone-mediated and rod-mediated filling-in with previously described photoreceptor densities. This represents the first investigation into rod-mediated filling-in. METHODS Fading times were recorded in nine volunteers using luminance-defined stimuli at eccentricities of 0 degrees , 2.5 degrees , 5 degrees , 10 degrees , and 20 degrees for high-contrast stimuli and 0 degrees , 1.25 degrees , 2.5 degrees , 3.75 degrees , and 5 degrees for low-contrast stimuli and were compared with CSw at each location. Fading times were also recorded at 0 degrees , 2.5 degrees , 5 degrees , 10 degrees , and 20 degrees using red-green stimuli and at 5 degrees , 10 degrees , and 20 degrees under dark-adapted conditions and compared with cone and rod densities in the nasal, temporal, superior, and inferior hemimeridians. RESULTS Consistent anisotropy was evident in central and peripheral fields for luminance-defined targets and for chromatic targets, with horizontal meridians taking longer to fill in. The same pattern was observed in CSw and the previously described cone density. Log FT and CSw were correlated irrespective of visual field location. The ratio of rod-mediated FT to rod density decreased with eccentricity. CONCLUSIONS Anisotropy between horizontal and vertical meridians for FT is consistent in central and peripheral fields, reflecting patterns in CSw and cone density. This is discussed in the context of cortical processes underlying filling-in. For rod-mediated filling-in, more peripheral eccentricities are characterized by reduced FTs in relation to rod density.
The effect of a selective cyclooxygenase-2 inhibitor (celecoxib) on chronic periodontitis.

BACKGROUND Non-steroidal anti-inflammatory agents inhibit the production of cyclooxygenase (COX) products and can attenuate bone loss. In this double-masked, placebo-controlled, randomized clinical trial, the efficacy of celecoxib (COX-2 inhibitor) was evaluated in conjunction with scaling and root planing (SRP) in subjects with chronic periodontitis (CP). METHODS A total of 131 subjects were randomized to receive SRP and either celecoxib (200 mg) or placebo every day for 6 months. Clinical outcomes were assessed every 3 months for 12 months as mean changes from baseline. Primary efficacy parameters included clinical attachment level (CAL) and probing depth (PD). Secondary outcomes included percentages of tooth sites with CAL loss or gain > or =2 mm, changes in bleeding on probing (BOP), plaque index, and mobility. Prior to analysis, tooth sites were grouped based on baseline PD as shallow (1 to 3 mm), moderate (4 to 6 mm), or deep (> or =7 mm). RESULTS Mean PD reduction and CAL gain were greater in the celecoxib group, primarily in moderate and deep sites, throughout the study (PD: 3.84 mm versus 2.06 mm, P <0.001; CAL: 3.74 mm versus 1.43 mm, P <0.0001 for deep sites at 12 months). The celecoxib group also exhibited a greater percentage of sites with > or =2 mm CAL gain and fewer sites with > or =2 mm CAL loss. Both groups showed improved plaque control and BOP scores. Demographic, social, and behavioral factors did not affect treatment outcomes. CONCLUSIONS Celecoxib can be an effective adjunctive treatment to SRP to reduce progressive attachment loss in subjects with CP. Its beneficiary effect persisted even at 6 months postadministration. However, given the increased cardiovascular risks associated with the use of this drug, close patient supervision and strict adherence to dosage and administration guidelines established by the Unites States Food and Drug Administration are of paramount importance.
The Hole in the Whole: A Response to Allen and March

Allen and March provide a critique of one of our papers in which we argue composites should be represented as entities/objects in a conceptual model rather than relationships/associations (Shanks et al. 2008). They contend we have addressed a non-issue. Furthermore, they argue our theoretical rationale and empirical evidence have flaws. In this paper, we provide a response to their arguments. We show that the issue we address is substantive. We show, also, that our theoretical analysis and empirical results are robust. We find, instead, that Allen and March's theoretical arguments and empirical evidence have flaws.
Beyond the Code of Ethics, Part I: Complexities of Ethical Decision Making in Social Work Practice

The authors have acquired experience in, and opinions on, ethical decision making while serving on a (U.S.) National Association of Social Workers (NASW) peer consultation ethics call line. The authors agree with scholars who view all human perceptions and activities as shaped by values, with the concurrent need to become more self-conscious about the ethical dimension of our daily life and professional practice. It is argued that our social work code of ethics is a necessary but insufficient tool for ethical decision making. The Code of Ethics (National Association of Social Workers, 1996) is frequently used as a risk management tool, offering guidelines for practice which may or may not be compatible with the goals of social justice for which social work ideally stands. Additionally, the unique and unexpected ways ethical issues emerge in clinical practice work against attempts to apply the Code as a rule book. Distinctions between ethical, legal, and clinical issues are difficult, given that the two latter domains have inevitable ethical implications. The authors urge readers to supplement a model of purely rational, ethical decision making with their emotions and intuition as shaped by our culture and our profession. Ethical judgments are best made in small groups where members bring different perspectives and intuitions to the process while agreeing on basic humanistic values.
Neural Signature of DCD: A Critical Review of MRI Neuroimaging Studies

The most common neurodevelopmental disorders (e.g., developmental dyslexia (DD), autism, attention-deficit hyperactivity disorder (ADHD)) have been the subject of numerous neuroimaging studies, leading to certain brain regions being identified as neural correlates of these conditions, referring to a neural signature of disorders. Developmental coordination disorder (DCD), however, remains one of the least understood and studied neurodevelopmental disorders. Given the acknowledged link between motor difficulties and brain features, it is surprising that so few research studies have systematically explored the brains of children with DCD. The aim of the present review was to ascertain whether it is currently possible to identify a neural signature for DCD, based on the 14 magnetic resonance imaging neuroimaging studies that have been conducted in DCD to date. Our results indicate that several brain areas are unquestionably linked to DCD: cerebellum, basal ganglia, parietal lobe, and parts of the frontal lobe (medial orbitofrontal cortex and dorsolateral prefrontal cortex). However, research has been too sparse and studies have suffered from several limitations that constitute a serious obstacle to address the question of a well-established neural signature for DCD.
The Current Role of Endourologic Management of Renal Transplantation Complications

Introduction. Complications following renal transplantation include ureteral obstruction, urinary leak and fistula, urinary retention, urolithiasis, and vesicoureteral reflux. These complications have traditionally been managed with open surgical correction, but minimally invasive techniques are being utilized frequently. Materials and Methods. A literature review was performed on the use of endourologic techniques for the management of urologic transplant complications. Results. Ureterovesical anastomotic stricture is the most common long-term urologic complication following renal transplantation. Direct vision endoureterotomy is successful in up to 79% of cases. Urinary leak is the most frequent renal transplant complication early in the postoperative period. Up to 62% of patients have been successfully treated with maximal decompression (nephrostomy tube, ureteral stent, and Foley catheter). Excellent outcomes have been reported following transurethral resection of the prostate shortly after transplantation for patients with urinary retention. Vesicoureteral reflux after renal transplant is common. Deflux injection has been shown to resolve reflux in up to 90% of patients with low-grade disease in the absence of high pressure voiding. Donor-gifted and de novo transplant calculi may be managed with shock wave, ureteroscopic, or percutaneous lithotripsy. Conclusions. Recent advances in equipment and technique have allowed many transplant patients with complications to be effectively managed endoscopically.
Challenging gender practices: Intersectional narratives of sibling relations and parent–child engagements in transnational serial migration

This article aims to contribute to the currently sparse literature on transnational families and gender. It focuses on the retrospective accounts of Caribbean-born adults who as children were serial migrants, joining their parents in the UK following a period of separation. It considers aspects of their relationships with their siblings and with their mothers and fathers. The article illuminates what the serial migrants viewed as contradictory everyday practices that produced ‘non-shared environments’. It discusses three ways in which transnationalism appeared to be a central part of the serial migrants’ family lives. First, it was embodied. Second, it was lived as cultural difference between Caribbean-born and UK-born siblings. Third, it was reported to be evident in parental practices. The article illustrates the importance of viewing gendered narratives in a psychosocial intersectional perspective.
Desenvolvimento sociocognitivo e histórias infantis: subsídios para a prática docente

This study aimed to evaluate the occurrence of mental terms in a sample of Brazilian children's books and the possibility to explore narratives through the process of the social information model. Based on international studies, 119 Brazilian books directed to preschoolers were analyzed considering four axes: (a) words and expressions denoting mental states; (b) convergence figure/mental state; (c) situational irony and false belief and (d) situations giving social tips. The results indicate a high number of references to mental states (99%), with predominance of cognitive (42%) and emotional terms (39%), high convergence figure/mental state (74%), presence of irony (21%) and false belief (13,5%), and expressive occurrence of situations involving internal and external social tips (98%). The use of children's books as a resource to promote social-cognitive development is discussed and support is presented with a view to contribute to the practice of preschool teachers.
Development of a Diagnostic PCR Assay Targeting the Mn-Dependent Superoxide Dismutase Gene (sodA) for Identification of Streptococcus gallolyticus

ABSTRACT A PCR-based assay to identify Streptococcus gallolyticus has been developed. The assay uses an oligonucleotide primer pair targeting a partial sequence of the manganese-dependent superoxide dismutase gene (sodA). The assay distinguished members of the S. gallolyticus group from other, closely related taxa successfully by yielding a 408-bp specific amplicon.
Service Learning in Student Teaching: “What's Social Studies For?”

Abstract Education for a democratic society has been a powerful, long-standing rationale for the entire public school curriculum. But the idea has special relevance for social studies education. This study examined the extent to which notions of democratic citizenship developed in the personal theory of teaching held by one preservice social studies teacher during a student teaching semester. The research posed the question of whether this beginning teacher's incorporation of service learning into his curriculum would serve as a catalyst to help him develop ideas about the role of social studies and what it means to educate for democratic citizenship. Though he believed service-learning was his most powerful and effective teaching during the semester, this student teacher mostly failed to connect what he learned from service-learning to his developing rationale for social studies. The results raise questions about the possibilities for democratic projects in teacher education and the supports needed to facilitate such work.
