Selected AbstractsSocial approach in pre-school children with Williams syndrome: the role of the faceJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 3 2010H. F. Dodd Abstract Background Indiscriminate social approach behaviour is a salient aspect of the Williams syndrome (WS) behavioural phenotype. The present study examines approach behaviour in pre-schoolers with WS and evaluates the role of the face in WS social approach behaviour. Method Ten pre-schoolers with WS (aged 3,6 years) and two groups of typically developing children, matched to the WS group on chronological or mental age, participated in an observed play session. The play session incorporated social and non-social components including two components that assessed approach behaviour towards strangers; one in which the stranger's face could be seen and one in which the stranger's face was covered. Results In response to the non-social aspects of the play session, the WS group behaved similarly to both control groups. In contrast, the pre-schoolers with WS were significantly more willing than either control group to engage with a stranger, even when the stranger's face could not be seen. Conclusion The findings challenge the hypothesis that an unusual attraction to the face directly motivates social approach behaviour in individuals with WS. [source] Are We all Natural Dualists?THE JOURNAL OF THE ROYAL ANTHROPOLOGICAL INSTITUTE, Issue 3 2001A Cognitive Developmental Approach The article takes to task the well-established anthropological claim that non-Western peoples are free from the traps of dualistic thinking. Although Vezo informants in Madagascar produce statements that could be used to support such a claim, experimental procedures that target their inferential reasoning reveal that they systematically differentiate between mind and body, between the biological processes that determine the organism and the social processes that shape personhood. This suggests that there is a significant discrepancy between people's explicit linguistic statements and their implicit theoretical knowledge. Moreover, developmental data show that such implicit theoretical presuppositions are essential to the production and transmission of cultural knowledge. Thus, Vezo children, who do not as yet differentiate between the biological mechanism of birth and the social mechanism of nurture, are still unable to grasp a salient aspect of Vezo culture, namely the causally integrated set of ideas that guide the way adults classify the social world. These findings have significant theoretical and methodological implications for the constitution of anthropological knowledge. [source] A comparative study of student performance in traditional mode and online mode of learningCOMPUTER APPLICATIONS IN ENGINEERING EDUCATION, Issue 1 2007Qiping Shen Abstract There has been interest for many decades in comparing the effectiveness of technology-delivered instruction with traditional face-to-face teaching and measurable student outcomes have been an important indicator. Having pointed to salient aspects of the current academic environment and to some of the key literature in this area, this article analyses the performance of two groups of students studying in the traditional mode and the online mode in a masters program delivered by a Department of Computing at a university in Hong Kong. Over 2,000 students have participated in the study between 2000 and 2004. This article includes a comparison of the results between different delivery modes of study each year as well as between different classes over the 4-year period. Although traditional mode students have achieved a slightly better performance in examinations in comparison with online mode students, the article concludes that there are no significant differences in overall performance between the students. With the impact of technologies on higher education and the demands of a complex and rapidly changing society in the 21st century, this Hong Kong study contributes to the literature that finds mode of study is not a key determinant of success. © 2007 Wiley Periodicals, Inc.

Wasserman Since 1918, hand,arm vibration (HAV) exposure, principally from but not limited to vibrating power tools and processes, affects some 1.5 to 2 million regularly exposed U.S. workers and many more worldwide. These HAV exposures usually lead to an irreversible disease of the fingers/hands called hand,arm vibration syndrome whose prevalence is as high as 50% in exposed worker populations. HAVS results not only in hand,arm deterioration, but invariably job loss. To help combat the mounting HAV problem, domestic and international consensus HAV exposure standards were developed and promulgated in the early 1980s; but for the first time, the European Union in 2005 passed into law exposure standards for both HAV and whole-body vibration. In response, in 2006 in the United States, the American National Standards Institute (ANSI) developed, replaced, and promulgated its 1986 HAV exposure standard S3.34 with a completely revised HAV standard,S2.70-2006,thus ushering in new profound implications for power tool users and tool manufacturers and countless related manufacturing operations throughout the United States. The background, salient aspects, safety and health, and manufacturing implications of this new ANSI S2.70 HAV standard are discussed. © 2008 Wiley Periodicals, Inc. [source] FIAT control of osteoblast activityJOURNAL OF CELLULAR BIOCHEMISTRY, Issue 3 2010René St-Arnaud Abstract The basic domain-leucine zipper transcription factor activating transcription factor 4 (ATF4) regulates most functions of the osteoblast. It is therefore not surprising that its activity should be regulated through several mechanisms. Factor inhibiting ATF4-mediated transcription (FIAT) is a leucine zipper nuclear molecule lacking a basic domain for DNA binding that interacts with ATF4 to repress its transcriptional activity. FIAT expression was monitored in parallel with ATF4 during osteoblastogenesis. The mechanism of ATF4 repression by FIAT was investigated through structure,function analysis. The physiological significance of FIAT expression in osteoblasts was studied through silencing FIAT in osteoblasts by RNA interference, as well as through characterization of two genetic mouse models: FIAT transgenic mice which overexpress FIAT in osteoblasts, and FIAT knockout mice. Studies to date show that FIAT and ATF4 are co-expressed in osteoblasts, and that FIAT inhibition of matrix mineralization requires dimerization with ATF4 through the second leucine zipper. Furthermore, transgenic mice overexpressing FIAT exhibit osteopenia. The phenotype of FIAT knockout mice is still under evaluation but the salient aspects are discussed here. Taken together, the results accumulated to date support the hypothesis that FIAT is a transcriptional repressor that modulates osteoblast function. J. Cell.

[source] Phylogeography of colonially nesting seabirds, with special reference to global matrilineal patterns in the sooty tern (Sterna fuscata)MOLECULAR ECOLOGY, Issue 11 2000John C. Avise Abstract Sooty tern (Sterna fuscata) rookeries are scattered throughout the tropical oceans. When not nesting, individuals wander great distances across open seas, but, like many other seabirds, they tend to be site-faithful to nesting locales in successive years. Here we examine the matrilineal history of sooty terns on a global scale. Assayed colonies within an ocean are poorly differentiated in mitochondrial DNA sequence, a result indicating tight historical ties. However, a shallow genealogical partition distinguishes Atlantic from Indo-Pacific rookeries. Phylogeographic patterns in the sooty tern are compared to those in other colonially nesting seabirds, as well as in the green turtle (Chelonia mydas), an analogue of tropical seabirds in some salient aspects of natural history. Phylogeographic structure within an ocean is normally weak in seabirds, unlike the pronounced matrilineal structure in green turtles. However, the phylogeographic partition between Atlantic and Indo-Pacific rookeries in sooty terns mirrors, albeit in shallower evolutionary time, the major matrilineal subdivision in green turtles. Thus, global geology has apparently influenced historical gene movements in these two circumtropical species.

Abstract While the competencies and theory relevant to public health nursing (PHN) practice continue to be described, much less attention has been given to the knowledge derived from practice (clinical know-how) and the development of PHN expertise. A study was designed to address this gap by recruiting nurses with varied levels of experience and from various practice sites. A convenience sample of 28 public health nurses and seven administrators/supervisors were interviewed. A subsample, comprised of less-experienced public health nurses, were followed longitudinally over an 18-month period. Data included more than 130 clinical episodes and approximately 900 pages of transcripts and field notes. A series of interpretive sessions focused on identifying salient aspects of the text and comparing and contrasting what showed up as compelling, puzzling, and meaningful in public health nurses' descriptions. This interpretive analysis revealed changes in understanding of practice and captured the development of clinical know-how. In Part 1, we describe the sample, study design, and two aspects of clinical knowledge development,grappling with the unfamiliar and learning relational skills,that surfaced in nurses' descriptions of early clinical practice. In Part 2, which is to be published in the next issue of Public Health Nursing (SmithBattle, Diekemper, & Leander, 2004), we explore gradual shifts in public health nurses' understanding of practice that led to their engagement in upstream, population-focused activities. Implications of these findings for supporting the clinical learning of public health nurses and the development of expertise are described. [source] 100 Years On: Who are the Inheritors of the ,New Liberal' Mantle?THE POLITICAL QUARTERLY, Issue 1 2007ALISON HOLMES The ,great divorce' of progressive politics at the end of the nineteenth century permanently altered British politics. While the philosophies of the Labour movement and the Liberal Party had many common elements, ideologically they diverged on issues of the role of liberty and the state in relation to the individual and the community to the point that they became irreconcilable. New Liberalism was one result of that debate. Contemporary political debate reflects many of the same features as the turmoil present a century ago, and the Labour Party and the Liberal Democrats are again contesting much of the same ground. This article seeks to draw out the salient aspects of this debate to conclude which, if either, party is the inheritor of the New Liberal tradition. [source] | |||||||||||||||||||
