Physical education in Tunisia: teachers' practical epistemology, students' positioning and gender issues

This paper explores gendered student learning in physical education (PE) viewed as a situated emerging process involving a triadic relationship between teacher, student(s) and forms of knowledge that are socioculturally bounded. It concerns gymnastic teaching and learning in Tunisia. It was conducted against the background of the Joint Action Studies in Didactics (JASD). Three Tunisian PE teachers having different expertise and experience and 12 male and female students with contrasted skill levels were observed within a gymnastics unit. Based on the video record of the lessons and on teachers' interviews, the findings stress the personal, institutional and cultural dimensions that shape the observed PE practices with special attention to the gendered content taught and learned. The use of the JASD framework highlights the intertwined processes during classroom interactions that influence the co-construction of gendered learning. It makes visible the interplay between the teacher's practical epistemology and the students' gender positioning and its consequence on inequalities in terms of students' learning and the maintenance of gender order in the gym.
Clinical evaluation of total and lipid bound sialic acid levels in oral precancer and oral cancer

Aims: Special attention has been given to define the biochemical changes in cell-surface glycoproteins and glycolipids that take place during malignant transformation. This study was thus designed to explore the clinical utility of total and lipid bound sialic acid (LSA) in patients with oral precancer and oral cancer. Materials and Methods: Blood samples were obtained from 95 subjects divided into three groups, namely healthy individuals, oral cancer, and precancer. Serum total and LSA levels were determined using periodate-thiobarbituric acid method and Katopodis et al. method, respectively. Finally, spectrophotometricreadings were obtained. Results: Mean values of serum sialic acid (total and lipid bound) in oral cancer were significantly higher than control and the precancer group (P<0.001). The multivariate analysis data revealed progressive rise in total and LSA, which was statistically significant with clinical stage of the cancer. Conclusion: Serum sialic acid levels can differentiate between patients with oral precancer and oral cancer. It could be used as an adjunct to diagnosis, monitor response to therapy, and assess the staging of cancer.
West Nile Virus Transmission in Resident Birds, Dominican Republic

We report West Nile virus (WNV) activity in the Dominican Republic for the first time. Specific anti-WNV antibodies were detected in 5 (15%) of 33 resident birds sampled at one location in November 2002. One seropositive bird was <4 months old, indicating a recent infection.
Reduced-toxicity conditioning prior to allogeneic stem cell transplantation improves outcome in patients with myeloid malignancies

The introduction of reduced intensity/toxicity conditioning regimens has allowed allogeneic hematopoietic cell transplantation to be performed in patients who were previously considered too old or otherwise unfit. Although it led to a reduction in non-relapse mortality, disease control remains a major challenge. We studied the outcome of 165 patients with acute myeloid leukemia (n=124) or myelodysplastic syndrome (n=41) transplanted after conditioning with fludarabine (30 mg/m2/day for 5 days), intravenous busulfan (either 260 mg/m2: reduced intensity conditioning, or 390–520 mg/m2: reduced toxicity conditioning), and rabbit anti-thymoglobulin (2.5 mg/kg/day for 2 days). The median age of the patients at transplantation was 56.8 years. The 2-year relapse incidence was 29% (23% versus 39% for patients transplanted in first complete remission and those transplanted beyond first complete remission, respectively; P=0.008). The 2-year progression-free survival rate was 57% (95% CI: 49.9–65). It was higher in the groups with favorable or intermediate cytogenetics than in the group with unfavorable cytogenetics (72.7%, 60.5%, and 45.7%, respectively; P=0.03). The cumulative incidence of grades 2–4 and 3–4 acute graft-versus-host disease at day 100 was 19.3% and 7.9%, respectively. The cumulative incidence of chronic graft-versus-host disease at 1 year was 21.6% (severe forms: 7.8%). Non-relapse mortality at 1 year reached 11%. The 2-year overall survival rate was 61.8% (95% CI: 54.8–69.7). Unfavorable karyotype and disease status beyond first complete remission were associated with a poorer survival. This well-tolerated conditioning platform can lead to long-term disease control and offers possibilities of modulation according to disease stage or further development.
The Development of Children’s Orientations toward Moral, Social, and Personal Orders: More than a Sequence in Development

Lawrence Kohlberg first published details of his research on the development of moral judgments in Vita Humana (later titled Human Development). Along with a series of other articles and essays, he greatly influenced research on moral development. He was instrumental in moving the field out of the narrow confines of analyses of psychological mechanisms to inclusion of substantive philosophical definitions of the domain. He persuaded many researchers to take morality seriously as a realm pertaining to people’s thinking about how they ought to relate to each other and how social systems should be organized. Although several aspects of Kohlberg’s theoretical formulations are now not widely accepted, most researchers (though not all) are concerned with combining epistemological considerations with psychological analyses and view children as possessing moral capacities not solely imposed by adults. One of these theoretical perspectives, discussed in this essay, is based on distinctions among social domains. Problems in current research, especially on morality and neuroscience, that fails to attend to epistemological considerations are discussed.
Organizational and Professional Identification

This study examined organizational and professional identification among a group of professional employees-the journalists at one daily metropolitan newspaper. It used two kinds of data to compare identification with these two targets and, further, to examine the relationships between identifications, autonomy, and job satisfaction. Survey results revealed significantly higher identification with the profession of journalism than with the journalists' employing newspaper. Journalists' accounts in individual interviews and the researcher's observation of on-the-job talk provided the context for interpreting the quantitative results. Accounts and observations contributed explanations for the blurred boundaries between the targets found in the survey results. In addition, the qualitative data demonstrated the role of anticipatory and vocational socialization and work group demographics in the identifications of this group.

Basque L2 development in immersion school settings

The aim of this article is to study the development of Basque L2 by Spanish L1 children who attend school in a total immersion programme where Basque is the vehicular language. Narratives based on an adult model produced at ages 5 and 8 are analysed in order to better understand the acquisition process of Basque L2 in an immersion school context. Basque L1 children who are also educated in Basque from preschool age constitute a reference group. The same subjects participate in the research at both ages, which gives a longitudinal as well as a cross-sectional approach to the study. The degree of narrative autonomy, the organisation of the narrative structure and features of nominal and verbal cohesion and some metalinguistic strategies are analysed. The results show similar skills in both groups, and the differences are not always in favour of the L1 subjects. On the whole, L2 subjects seem to reproduce the adult model more closely. This study contributes to a better understanding of L2 development in a school context, focussing on the positive effects of Basque immersion programmes.
Integrating sport psychology and sports medicine in research: The dilemmas

Abstract The recent acceleration of interest in conducting sport psychology research within sports medicine settings has prompted an introspection on the stringency of sport injury-focused research protocols and methodology. Much of the literature relating to the psychology of sport injury is anecdotal, comprised of conjecture, or is an extrapolation from allied psychological study. In addition, retrospective studies, involving the recall of an unpleasant event (i.e., sport injury) proliferate the literature. Quality research that integrates sport psychology and sports medicine presents a unique challenge because of the multifactorial nature of sport injury and the necessity for sound interpretation of research outcomes relative to the nature of psychology. sport, and injury. Confounding and complicating aspects of this integrated research include definition of injury variables, timing of data collection. evaluation of pain. and the physiological sequelae of injury. Research and methodological issues rela.
Quality of Life in Liaison Psychiatry

Background This exploratory study investigates the performance of the Health Measurement Questionnaire (HMQ), as compared with the Psychiatric Assessment Schedule (PAS) and the Nottingham Health Profile (NHP), and compares self- and observer-completed measures. Method A total of 138 medical patients scoring over the screening threshold for probable psychiatric illness completed the HMQ, NHP and PAS, and were rated by a psychiatrist on Rosser disability and distress. Results HMQ disability correlated well with NHP and PAS physical health items, while HMQ distress correlated well with the NHP emotional reactions and PAS Index of Definition. There was significant correlation between self-report and psychiatrist ratings, the latter being more sensitive to distress. Conclusion The HMQ is a useful measure of generic health status in liaison psychiatry settings.
Phospholipase C Gamma 2 Is Critical for Development of a Murine Model of Inflammatory Arthritis by Affecting Actin Dynamics in Dendritic Cells

Background Dendritic cells (DCs) are highly specialized cells, which capture antigen in peripheral tissues and migrate to lymph nodes, where they dynamically interact with and activate T cells. Both migration and formation of DC-T cell contacts depend on cytoskeleton plasticity. However, the molecular bases governing these events have not been completely defined. Methodology/Principal Findings Utilizing a T cell-dependent model of arthritis, we find that PLCγ2−/− mice are protected from local inflammation and bone erosion. PLCγ2 controls actin remodeling in dendritic cells, thereby affecting their capacity to prime T cells. DCs from PLCγ2−/− mice mature normally, however they lack podosomes, typical actin structures of motile cells. Absence of PLCγ2 impacts both DC trafficking to the lymph nodes and migration towards CCL21. The interaction with T cells is also affected by PLCγ2 deficiency. Mechanistically, PLCγ2 is activated by CCL21 and modulates Rac activation. Rac1/2−/− DCs also lack podosomes and do not respond to CCL21. Finally, antigen pulsed PLCγ2−/− DCs fail to promote T cell activation and induce inflammation in vivo when injected into WT mice. Conversely, injection of WT DCs into PLCγ2−/− mice rescues the inflammatory response but not focal osteolysis, confirming the importance of PLCγ2 both in immune and bone systems. Conclusions/Significance This study demonstrates a critical role for PLCγ2 in eliciting inflammatory responses by regulating actin dynamics in DCs and positions the PLCγ2 pathway as a common orchestrator of bone and immune cell functions during arthritis.
Static postural balance in healthy individuals: Comparisons between three age groups

The aim of the study was to compare static postural balance of healthy individuals of three age groups in different conditions of support and vision. Seventy one individuals, divided into 3 groups, were analyzed: young group (YG: 22.2 ± 2.1 years), middle aged group (MAG: 50.7 ± 5.7 years) and older individuals group (EG: 66.8 ± 5.4 years). Their balance was tested on a force platform, under 3 support and 3 visual conditions. Measures included: total (TD), anterior-posterior (APD) and mediolateral displacement (MLD) of the center of pressure (CoP). ANOVA revealed significant differences for interactions between group X support conditions and group X visual conditions for the 3 variables (p<0.01), with greater displacements for the MAG and EG groups during single-leg stance with partial and occluded vision (p<0.05). Static postural balance decreased over time in healthy individuals, and conditions of support and visual negatively affected balance with the increment of age.
The Functional Role of Individual-Alpha Based Frontal Asymmetry in the Evaluation of Emotional Pictures: Evidence from Event-Related Potentials

The perceptual processing of emotional stimuli is subject to the regulation of brain function. This study investigated whether frontal electroencephalography (EEG) alpha asymmetry at resting conditions predicted the evaluation of emotional picture stimuli by event-related potentials (ERPs). In this study, participants first completed a 2-min resting task, and then passively viewed emotional pictures. The results showed that left active individuals had smaller frontal EEG alpha asymmetry scores to negative pictures than to positive and neutral pictures, whereas right active individuals had similar frontal EEG alpha asymmetry scores to negative, positive, and neutral pictures. Furthermore, the study showed a larger P300 to negative pictures than to positive and neutral pictures for left active individuals; however, there were no significant ERP differences to negative, positive, and neutral pictures for right active individuals. These findings suggest that frontal EEG alpha asymmetry at resting conditions can reflect interindividual differences in emotional perception tendencies to emotional picture stimuli.
Complementarity of Interpersonal Circumplex Traits

The existence of interpersonal complementarity at a stylistic level using the Interpersonal Adjectives Scales (IAS) and the optimal definition of complementarity were the foci of the study. The IAS ratings made by three samples of college students were used: 265 rated both of their parents, 346 rated themselves and their closest friend, and 136 rated how they expected themselves and the other participant to behave in one of three very different situations. The correlation matrices between the scores of the two interactants in each sample were examined using the randomization test of hypothesized order relations to determine if complementarity existed. Results indicated support for the complementarity of traits in each sample and showed that the optimal orientation of dimensions of the IAS with respect to complementarity is 22.5 degrees greater than the orientation proposed by Leary and adopted by Wiggins.
Technology Ecosystem Governance

Technology platform strategies offer a novel way to orchestrate a rich portfolio of contributions made by the many independent actors who form an ecosystem of heterogeneous complementors around a stable platform core. This form of organising has been successfully used in smartphone, gaming, commercial software, and industrial sectors. Technology ecosystems require stability and homogeneity to leverage common investments in standard components, but they also need variability and heterogeneity to meet evolving market demand. Although the required balance between stability and evolvability in the ecosystem has been addressed conceptually in the literature, we have less understanding of its underlying mechanics or appropriate governance. Through an extensive case study of a business software ecosystem consisting of a major multinational manufacturer of enterprise resource planning software at the core and a heterogeneous system of independent implementation partners and solution developers on the periphery, our research identifies three salient tensions that characterize the ecosystem: standard–variety, control–autonomy, and collective–individual. We then highlight the specific ecosystem governance mechanisms designed to simultaneously manage desirable and undesirable variance across each tension. Paradoxical tensions may manifest as dualities, where tensions are framed as complementary and mutually enabling. Alternatively, they may manifest as dualisms, where actors are faced with contradictory and disabling “either…or” decisions. We identify conditions where latent, complementary tensions become manifest as salient, contradictory tensions. By identifying conditions in which complementary logics are overshadowed by contradictory logics, our study further contributes to the understanding of the dynamics of technology ecosystems, as well as the effective design of technology ecosystem governance that can explicitly embrace paradoxical tensions toward generative outcomes.
Homology modeling with internal coordinate mechanics: Deformation zone mapping and improvements of models via conformational search

Five models by homology containing insertions and deletions and ranging from 33% to 48% sequence identity to the known homologue, and one high sequence identity (85%) model were built for the CASP2 meeting. For all five low identity targets: (i) our starting models were improved by the Internal Coordinate Mechanics (ICM) energy optimization, (ii) the refined models were consistently better than those built with the automatic SWISS‐MODEL program, and (iii) the refined models differed by less than 2% from the best model submitted, as judged by the residue contact area difference (CAD) measure [Abagyan, R.A. , Totrov, M.J. Mol. Biol. 268:678–685, 1997]. The CAD measure is proposed for ranking models built by homology instead of global root‐mean‐square deviation, which is frequently dominated by insignificant yet large contributions from incorrectly predicted fragments or side chains. We demonstrate that the precise identification of regions of local backbone deviation is an independent and crucial step in the homology modeling procedure after alignment, since aligned fragments can strongly deviate from the template at various distances from the alignment gap or even in the ungapped parts of the alignment. We show that a local alignment score can be used as an indicator of such local deviation. While four short loops of the meeting targets were predicted by database search, the best loop 1 from target T0028, for which the correct database fragment was not found, was predicted by Internal Coordinate Mechanics global energy optimization at 1.2 Å accuracy. A classification scheme for errors in homology modeling is proposed. Proteins, Suppl. 1:29–37, 1997. © 1998 Wiley‐Liss, Inc.
Televised Sports, Masculinist Moral Capital, and Support for the U.S. Invasion of Iraq

Data from a survey of 1,048 Americans conducted in summer 2003 are used to demonstrate the existence of a “televised masculinist sport–militaristic nationalism complex” that contributed support for the U.S. invasion of Iraq. Involvement in televised masculinist sports is robustly correlated with support for invading Iraq, the doctrine of preventive attacks, and strong patriotic feelings for the United States. Critical feminists and figurationalists posit a linkage between war and masculinist sports that is grounded in a macho or hypermasculinity found most in combat sports such as football. Using Lakoff's study of the conservative worldviewand Lamont'swork on moral boundaries, the author develops an alternative conception of “masculinist moral capital” that better explains the gender and racial patterns of correlation between different types of televised sports and support for invading Iraq.
Post-basic nursing students’ reflections on their experiences of dialogic mediation

This article presents post-basic nursing students’ reflections on the way they experienced the pedagogy of dialogic mediation. The study addressed current debates about appropriate teaching methodologies for students in such a degree course and the role of the nurse educator in this regard. The authors used a qualitative research approach and posed the following research question: What are students’ reflections of their experiences of dialogic mediation and the influence of this on their ideas of teaching and learning? The study involved a cohort of students ( n = 248) who were enrolled in a semester-long course in a post-basic nursing degree at a South African university. They were asked to respond to three open-ended questions regarding their experiences of a course that required engagement with a new teaching and learning strategy which expected active involvement. Data were collected from students’ written reflections and were analysed by searching for recurring themes and patterns. The findings revealed that students experienced extreme levels of frustration at the beginning of the course as their existing ideas about teaching and learning were challenged. They also found the new teaching techniques associated with this pedagogy to be demanding. However, once they understood the underlying principles and ideas, they began to understand the implications for their own learning and teaching practices. Hierdie artikel handel oor nabasiese-verpleegstudente se nadenke oor die wyse waarop hulle die pedagogie van dialogiese bemiddeling ervaar het. Hierdie studie het aandag gegee aan huidige debatte oor geskikte onderrigmetodologiee vir studente in so ‘n graadkursus en die rol van die verpleegkundige-opvoeder in hierdie opset. Die outeurs het ’n kwalitatiewe navorsingsbenadering gebruik en het die volgende navorsingsvraag gestel: Wat is studente se nadenke oor hul ervarings van dialogiese bemiddeling en die invloed daarvan op hul idees van onderrig en leer? Die studie het ’n spesiefike kohort studente ( n = 248) wat ingeskryf is by ’n semesterkursus in ’n nabasiese verpleeggraadprogram aan ’n Suid-Afrikaanse universiteit ingesluit. Hulle is gevra om op drie oop vrae te reageer oor hul ervarings van ’n kursus wat betrokkenheid by ’n nuwe onderrig- en leerstrategie vereis en waar aktiewe deelname verwag word. Data is uit studente se skriftelike nadenke ingesamel en is ontleed deur vir herhalende temas en patrone te soek. Die bevindings het getoon dat studente uiterste vlakke van frustrasie aan die begin van die kursus ervaar het, aangesien hul bestaande onderrig en leer uitgedaag is. Hulle het ook die nuwe onderrigtegniek wat met hierdie pedagogie gepaardgaan veeleisend gevind. Nadat hulle egter die onderliggende beginsels en idees verstaan het, het hulle begin om die implikasies van hul eie leer- en onderrigpraktyke te verstaan.
