Can anticonvulsant drug therapy 'cure' epilepsy?

There is now evidence to show that, as time passes, epilepsy, even if untreated, tends to undergo spontaneous remission in a significant proportion of patients. The question therefore arises as to whether anticonvulsant drug therapy increases this chance of the patient with epilepsy ultimately entering a terminal remission which continues after the treatment is withdrawn, Le. whether anticonvulsant drug therapy itself may sometimes cure epilepsy. There are no well-designed studies available in the literature that provide a clear answer to this question. However, data from a number of investigations carried out for other purposes can be used to see whether contemporary anticonvulsant drug therapy is associated with higher rates of expected untreated terminal remission than those that apply for never-treated patients with epilepsy, or for those whose anticonvulsant treatment has probably been inadequate for various social or historical reasons. Despite the admitted uncertainties inherent in drawing conclusions from such material, there appears to be a reasonably consistent tendency for contemporary anticonvulsant drug treatment to be associated with a greater chance of achieving probable cure of epilepsy. Therefore it would appear premature to take the view that contemporary anticonvulsant drug therapy does no more than suppress epileptic seizures until epilepsy remits spontaneously, or fails to remit, with the passing of time.

The social construction of PETE in higher education: Toward a research agenda

The focus of this paper is the social construction of physical education teacher education (PETE) and its fate within the broader process of curriculum change in the physical activity field. Our task is to map the dimensions of a research program centered on the social construction of the physical activity field and PETE in higher education. Debates in the pages of Quest and elsewhere over the past two decades have highlighted not only the contentious nature of PETE practices and structures but also that PETE is changing. This paper offers one way of making sense of the ongoing process of contestation and struggle through the presentation of a theoretical framework. This framework, primarily drawing upon the work of Lave and Wenger (1991) and Bernstein (1990, 1996), is described before it is used to study the social construction of PETE in Australia. We assess the progress that has been made in developing this research program, and the questions already evident for further developments of a program of study of the physical activity field in higher education.

Curriculum development for professional ethics in Australian human service university programmes

Australian academics and practitioners in the human services are particularly susceptible to social, political and economic influences in respect of their relevance, viability and operations. In fact, it can be argued that the impact of these influences has placed human service practitioners and academics in a perpetual state of vulnerability. Australian universities have been challenged to make their programmes more relevant and viable to the community at large, and practitioners face increasing workloads with limited resources based on restricted fiscal allocation, and the changing relationship between government and service providers. Drawing on interview data from twenty-one (n = 21) practitioners, this article highlights their identified problems regarding the notion of professionalism in the human services with a particular focus on ethical dilemmas in human service practice. Gleaning these details will be a basis for recommending necessary professionalethics curricula content in human services programmes offered in Australian universities. Moreover, while the research data is Australian based, the authors contend that the universal theories and principles underpinning human service practice justify the significance and value of the data as an important source for international consideration in curriculum development of human service academic programmes.

Finding gold in our shadow: psychotherapy and the shadow syndrome

Drawing on the work of Carl Jung and Robert Bly, Yaro Starak explores how 'shadow work' can be used within a Gestalt group therapy environment to uncover the 'gold in our shadow bags' - hidden inner strengths and resources that we were previously unaware of that may lead to healing and transformation.

A field trial of the effect of improved piglet management on smallholder sow productivity in the Philippines

We conducted a randomised, controlled field trial during 1998/1999 to evaluate the hypothesis that improved piglet management would improve the reproductive performance of smallholder sows. Simple changes were introduced into the treatment herds including the construction of a heated piglet-separation pen, vitamin injections, creep feeding and early weaning. The control herds were unchanged. Data were collected from all sows in each enrolled herd over two farrowings. We enrolled 176 sows, including 170 (96 treatment and 74 control) sows that remained throughout the study period. Significant differences in the reproductive performance of treatment and control sows were recorded for interfarrowing interval (median 176 versus 220 days), average number liveborn over 2 litters (11 versus 12), and average preweaning mortality over 2 litters (0 versus 37%). Based on a discount rate of 17%, the benefit-cost ratio of the treatment was 11.1 and 12.1 over 3 and 5 years, respectively. (C) 2001 Elsevier Science B.V. All rights reserved.

Using the World Wide Web to revolutionise technology transfer and training in the water and wastewater industries

Industry professionals of the near future will be supported by an IT infrastructure that enables them to complete a task by drawing on resources and people with expertise anywhere in the world, and access to knowledge through specific training programs that address the task requirements. The increasing uptake of new technologies enables information to reach a diverse population and to provide flexible learning environments 24 hours a day, 7 days a week. This paper examines one of the key areas where the World Wide Web will impact on the water and wastewater industries, namely technology transfer and training. The authors will present their experiences of developing online training courses for wastewater industry professionals over the last two years. The perspective is that of two people working at the coalface.

Lot-fed goats - the advantages of using an enriched environment

By reducing the stress associated with high stocking density in a feedlot it is likely that goats will utilise their feed more efficiently and suffer fewer health problems. One possible method of reducing stress is to enrich the feedlot environment. In a feedlot of 160 castrated goats (average weight 24.6 +/- 2.6 kg), 2 types of feedlot structures were compared; a typical feedlot and an 'environmentally enriched' feedlot, and goats stocked at 2 densities; a high stocking density (1667 goats/ha) and a relatively low stocking density (897 goats/ha). Over a 42-day period, environmental enrichment (old car/truck tyres and wooden railway sleepers to climb on and PVC piping to mouth and butt) increased weight gain by 83% (P = 0.04) and reduced the occurrence of inanition by 36%. Aggressive behaviour at the feed trough was reduced by 30% (P = 0.03) in pens of lower density when compared with pens of higher density. We conclude that lot feeding goats in environmentally enriched surroundings will increase feed conversion and reduce the number of non-eaters when compared with typically bare pen structures. Doubling in liveweight gain of goats within enriched feedlot surroundings when compared with typical structures shows promise as a cost effective, animal-welfare-orientated practice.

Quantum and classical fidelities for Gaussian states

We examine the physical significance of fidelity as a measure of similarity for Gaussian states by drawing a comparison with its classical counterpart. We find that the relationship between these classical and quantum fidelities is not straightforward, and in general does not seem to provide insight into the physical significance of quantum fidelity. To avoid this ambiguity we propose that the efficacy of quantum information protocols be characterized by determining their transfer function and then calculating the fidelity achievable for a hypothetical pure reference input state.

Transforming the architect: Ownership form and archetype change

The adoption of the incorporated form of ownership in preference to partnership is linked to the shift to a more modem organizational archetype in professional firms. Yet existing empirical research offers insufficient insight into the organizational processes of this transformation in different professional arenas. Where ownership and control become separated, there is a clearer theoretical explanation of the implications for the way the firm is run. Where ownership and control remain inside, the firm, however, the consequences are not so clear and have not been well explored. Using survey and interview materials derived from a study of architecture practices, we examine the processes by which differences based on ownership emerge. Then, by drawing on Weberian theories, where they are concerned with professionalization as a project with material and social rewards, we specify more clearly the context for change in professional firms' archetypes. This, we conclude, provides a stronger basis for understanding the change trajectories of firms within professions and comparative organizational analysis between professions.

The global sports-media nexus: Reflections on the 'Super League Saga' in Australia

Despite the social and (increasingly) commercial significance of sport and sporting bodies worldwide, they remain under-represented in the mainstream management literature. One of the more recent and dramatic examples of the global sports-media nexus is the 'Super League saga' in Australia. This paper recounts the tale of the Super League saga, providing a holistic analysis of the events and competitive issues arising by drawing on literatures concerning the economic nature and value of sports leagues, the resource-based view of the firm and the nature of psychological contracts in changing environments. The analysis confirms the general monopolistic tendencies of professional sports leagues in an increasingly global industry driven by the sports-media nexus, in accord with a number of comparable cases internationally. The particular conditions of the Australian marketplace that exacerbate this tendency beyond, for example, that found in the USA, and differences in the outcomes of battles between rival leagues are also considered. The Super League saga portrays the importance of effective management of resources key to the production of the 'rugby league product' including, among others, the often over-looked importance of careful management of local resources for the success of global strategies, and, where human resources are key, the importance of psychological contracting. The holistic analysis of the Super League saga in Australia affords lessons that extend well beyond the realm of sports.

The relation between the transversus abdominis muscles, sacroilac joint mechanics, and low back pain

Study Design. Two abdominal muscle patterns were tested in the same group of individuals, and their effects were compared in relation to sacroiliac joint laxity. One pattern was contraction of the transversus abdominis, Independently of the other abdominals; the other was a bracing action that used all the lateral abdominal muscles. Objectives. To demonstrate the biomechanical effect of the exercise for the transversus abdominis known to be effective in low back pain. Summary of Background Data. Drawing in the abdominal wall is a specific exercise for the transversus abdominis muscle (in cocontraction with the multifidus), which is used in the treatment of back pain. Clinical effectiveness has been demonstrated to be a reduction of 3-year recurrence from 75% to 35%. To the authors' best knowledge, there is not yet in vivo proof of the biomechanical effect of this specific exercise. This study of a biomechanical model on the mechanics of the sacroiliac joint, however, predicted a significant effect of transversus abdominis muscle force. Methods. Thirteen healthy individuals who could perform the test patterns were included. Sacroiliac joint laxity values were recorded with study participants in the prone position during the two abdominal muscle patterns. The values were recorded by means of Doppler Imaging of vibrations. Simultaneous electromyographic recordings and ultrasound imaging were used to verify the two muscle patterns. Results. The range of sacroiliac joint laxity values observed in this study was comparable with levels found in earlier studies of healthy individuals. These values decreased significantly in all individuals during both muscle patterns (P < 0.001). The independent transversus abdominis contraction decreased sacroiliac joint laxity (or rather increased sacroiliac joint stiffness) to a significantly greater degree than the general abdominal exercise pat-tern (P < 0.0260). Conclusions. Contraction of the transversus abdominis significantly decreases the laxity of the sacroiliac joint. This decrease in laxity is larger than that caused by a bracing action using all the lateral abdominal muscles. These findings are in line with the authors' biomechanical model predictions and support the use of independent transversus abdominis contractions for the treatment of low back pain.

Horizontal transmission of Shiga toxin-producing Escherichia coli within groups of dairy calves

To examine the dissemination of Shiga-toxigenic Escherichia coli (STEC) within cattle groups, dairy calves on two farms utilizing different calf-rearing practices were exposed to a traceable STEC strain. Test strain dissemination differed significantly between farms, with a higher prevalence being associated with group penning. Pen floors and calf hides may be the main environmental mechanisms of transmission. Dairy calf husbandry represents a control point for reducing on-farm STEC prevalence.

The role of transaction costs and institutional forces in the outsourcing of recruitment

This study investigated reasons for the outsourcing of a core HRM function, recruitment. Drawing from transaction costs and institutional theories, it was hypothesised that the pressure to minimise transaction costs and the presence of industry trends towards outsourcing would be positively associated with the outsourcing of recruitment. Survey data were gathered from 1I 7 HR professionals in Australia. Both hypotheses were partially supported. Specifically, the outsourcing of recruitment activities was positively associated with trust in the agency supplying the recruitment service and with the need to reduce internal labour but not fixed costs. With regard to institutional theory, the outsourcing of recruitment was positively associated with mimetic but not coercive forces. The study concludes that although most assumptions about recruitment agency use are expressed in economic terms, in reality, HRM practices are also influenced by forces exerted by the institutional environment in which organisations are located.

Amphitheater staging: In-the-round or to the front (and what about asides)?

When the existence in Utrecht of the DeWitt/Van Buchel drawing of the Swan Theater became known in 1888, William Poel was already seven years into his inquiries into the best means of staging the public amphitheater and great hall plays of the English Renaissance.1 I mention this to emphasize that the discourse came before the fact: the belief that Shakespeare's plays are best staged as it was then imprecisely imagined they had once been staged-simply, without elaborate settings or time-consuming scene changes, with direct actor-audience address, "in-the-round"-had as much to do with reactions against the late nineteenth-century stage's pictorialism, with its set-changing interruptions and cut-and-paste revisions to Shakespeare's texts, as it had to do with presenting the Bard "authentically." Some of the confusion caused by the uneasy mixing of historical scholarship and the assumptions and practices of our own contemporary theater profession can be glimpsed in the phenomenon of modern in-the-round staging, often claimed as a more "authentic" approach to Shakespeare in performance, but one which is then modified to make possible post-Stanislavsky acting methods and to satisfy modern audience expectations.

Everyday incivility: towards a benchmark

Commonplace incivility is a topic of longstanding interest within social theory, perhaps best exemplified by Goffman's studies of the interaction order. Nevertheless we know very little about its distribution and expression in everyday life. Current empirical work is dominated by criminological agendas. These tend to focus on more serious and illegal activities rather than minor deviant acts that are simply inconsiderate or rude. The paper reports findings from a focus group study conducted in Melbourne, Australia that set out to benchmark everyday incivilities. The results suggest that perpetrators of incivility have a surprisingly broad social distribution as does the range of locales that might be characterised as 'high risk'. Turning to the work of Putnam and Wolfe, we call for a research focus on low-level incivilities as key symptoms of the state of civic virtue and the strength of moral ties within civil society. Drawing on Virilio, Bauman and Durkheim, it is suggested that the experience of incivility is underpinned by the growth of freedom and movement in contemporary urban settings, and has ambivalent implications that not only invoke boundary maintenance and retreatism, but also offer the possibility for boundary expansion and tolerance of difference.
