Distance Education in Another Register: Uses and Appropriation of Technologies in Teacher Education

The article explores the relationships between distance education, information and communication technologies and teacher education. Its focus is on the interactive media and its uses in an in-service teacher education program, in Brazil, and on the ways the teachers used the technologies doing their own appropriateness. It departs from the presuppositions of the society of knowledge, that is, the close relationships between new technologies, continuing professional development and social inclusion, arguing that this paradigm is an ideological discourse. The article shows how the teachers have used the technologies in creative ways, calling the attention to the importance of this teachers` abilities as a basic skill to facing the challenges of the society of knowledge itself.

Discourse priming of homophones in individuals with dominant subcortical lesions, cortical lesions, and Parkinson’s disease

An on-line priming experiment was used to investigate discourse-level processing in four matched groups of subjects: individuals with nonthalamic subcortical lesions (NSL) ( n =10), normal control subjects ( n =10), subjects with Parkinsons disease (PD) ( n =10), and subjects with cortical lesions ( n =10). Subjects listened to paragraphs that ended in lexical ambiguities, and then made speeded lexical decisions on visual letter strings that were: nonwords, matched control words, contextually appropriate associates of the lexical ambiguity, contextually inappropriate associates of the ambiguity, and inferences (representing information which could be drawn from the paragraphs but was not explicitly stated). Targets were presented at an interstimulus interval (ISI) of 0 or 1000ms. NSL and PD subjects demonstrated priming for appropriate and inappropriate associates at the short ISI, similar to control subjects and cortical lesion subjects, but were unable to demonstrate selective priming of the appropriate associate and inference words at the long ISI. These results imply intact automatic lexical processing and a breakdown in discourse-based meaning selection and inference development via attentional/strategic mechanisms.

Tenure, mobility and retention of nurses in Queensland, Australia: 2001 and 2004

Aim. Data were collected on tenure, mobility and retention of the nursing workforce in Queensland to aid strategic planning by the Queensland Nurses Union (QNU). Background. Shortages of nurses negatively affect the health outcomes of patients. Population rise is increasing the demand for nurses in Queensland. The supply of nurses is affected by recruitment of new and returning nurses, retention of the existing workforce and mobility within institutions. Methods. A self-reporting, postal survey was undertaken by the QNU members from the major employment sectors of aged care, public acute and community health and private acute and community health. Results. Only 60% of nurses had been with their current employer more than 5 years. In contrast 90% had been in nursing for 5 years or more and most (80%) expected to remain in nursing for at least another 5 years. Breaks from nursing were common and part-time positions in the private and aged care sectors offered flexibility. Conclusion. The study demonstrated a mobile nursing workforce in Queensland although data on tenure and future time in nursing suggested that retention in the industry was high. Concern is expressed for replacement of an ageing nursing population.

Pedagogical work and the 'cult of the body': Considering the role of HPE in the context of the 'new public health'

Physical education, now often explicitly identified with health in contemporary school curricula, continues to be implicated in the (re)production of the 'cult of the body'. We argue that HPE is a form of health promotion that attempts to 'make' healthy citizens of young people in the context of the 'risk society'. In our view there is still work to be done in understanding how and why physical education (as HPE) continues to be implicated in the reproduction of values associated with the cult of body. We are keen to understand why HPE continues to be ineffective in helping young people gain some measure of analytic and embodied 'distance' from the problematic aspects of the cult of the body. This paper offers an analysis of this enduring issue by using some contemporary analytic discourses including 'governmentality', 'risk society' and the 'new public health'.

A Critical Appraisal of Narrative in Sport History: Reading the Surf Lifesaving Debate

All debates in history—who started the Cold War, how successful were the Chartists in achieving their aims, to what extent was the recession of the American frontier culturally significant in American history— are debates between competing narrative interpretations. Moreover, because the historical imagination itself exists intertextually within our own social and political environment, the past is never discovered set aside from everyday life. History is designed and composed in the here and now.

Field prevalence of Wolbachia in the mosquito vector Aedes albopictus

The endosymbiotic bacteria in the genus Wolbachia have been proposed as a potential candidate to deliver pathogen-blocking genes into natural populations of medically important insects. The successful application of Wolbachia in insect vector control depends on the ability of the agent to successfully invade and maintain itself at high frequency under field conditions. Here, we evaluated the prevalence of Wolbachia infections in a field population of the Wolbachia-superinfected mosquito Aedes albopictus. A field prevalence of 100% (n = 1,016) was found in a single population in eastern Thailand via polymerase chain reaction (PCR) testing of Wolbachia both from individual parent females and their corresponding F1 offspring. This is the first report of accurate Wolbachia prevalence in a field population of an insect disease vector. The prevalence of superinfection was estimated to be 99.41%. All single-infected individual mosquitoes (n = 6) were found to harbor group A Wolbachia. For this particular population, none was found to be single-infected with group B Wolbachia. Our results also show that PCR testing of field materials alone without checking F1 offspring overestimated the natural prevalence of single infection. Thus, the confirmation of infection status by means of F1 offspring was critical to the accurate estimates of Wolbachia prevalence under field conditions.

Interspecific and intraspecific horizontal transfer of Wolbachia in Drosophila

Cytoplasmic incompatibility (CI) in Drosophila simulans is related to infection of the germ line by a rickettsial endosymbiont (genus Wolbachia). Wolbachia were transferred by microinjection of egg cytoplasm into uninfected eggs of both D. simulans and D. melanogaster to generate infected populations. Transinfected strains of D. melanogaster with lower densities of Wolbachia than the naturally infected D. simulans strain did not express high levels of CI. However, transinfected D. melanogaster egg cytoplasm, transferred back into D. simulans, generated infected populations that expressed CI at levels near those of the naturally infected strain. A transinfected D. melanogaster line selected for increased levels of CI expression also displayed increased symbiont densities. These data suggest that a threshold level of infection is required for normal expression of CI and that host factors help determine the density of the symbiont in the host.

Emotion and attribution of intentionality in leader–member relationships

In this article, we present a model of emotions and attributions of intentionality within the leader–member relationship. The model is predicated on two central ideas. The first is that leadership is intrinsically an emotional process, where leaders display emotion and attempt to evoke emotion in their members. The second is that leadership is a process of social interaction and is therefore appropriately defined in terms of social, psychological theories such as the attribution theory. Our focus is on the perspective of members, not the leaders. Specifically, members' attributions about their leader's intentions influence how the members evaluate, interpret, and eventually label the leader's influence attempts as either “true” or “pseudo” transformational leadership. These attributions are determined by and themselves influence the members' emotions. We describe each of the elements of the model and conclude with a discussion of the implications of the model for theory, research, and practice.

Overview: The effect of affect in organizational settings

Nine of the chapters in this volume were sourced from the Fourth International Conference on Emotions and Organizational Life, held at Birkbeck College, London, in June 2004, and attended by 77 delegates. A record 46 papers were submitted to the conference, of which 27 were selected for presentation, in addition to one symposium. The nine papers chosen for this book were selected on the basis of their quality, interest, and appropriateness for the theme of this volume, “The effect of affect in organizational settings.” (A further set of papers has been selected to appear in Volume 2 of this book series.) We acknowledge in particular the assistance of the conference paper reviewers (see Appendix), who returned high-quality reviews in a very short time.
