Selected AbstractsMinting in Vandal North Africa: coins of the Vandal period in the Coin Cabinet of Vienna's Kunsthistorisches MuseumEARLY MEDIEVAL EUROPE, Issue 3 2008Guido M. Berndt This paper offers a re-examination of some problems regarding the coinage of Vandal North Africa. The coinage of this barbarian successor state is one of the first non-imperial coinages in the Mediterranean world of the fifth and sixth centuries. Based on the fine collection in the Coin Cabinet of Vienna's Kunsthistorisches Museum, this article questions the chronology of the various issues and monetary relations between the denominations under the Vandal kings, especially after the reign of Gunthamund (484,96). The Vandals needed and created a solid financial system. In terms of political, administrative and economic structures they tried to integrate their realm into the changing world of late antiquity and the early Middle Ages. [source] A structured and dynamic framework to advance traits-based theory and prediction in ecologyECOLOGY LETTERS, Issue 3 2010Colleen T. Webb Ecology Letters (2010) 13: 267,283 Abstract Predicting changes in community composition and ecosystem function in a rapidly changing world is a major research challenge in ecology. Traits-based approaches have elicited much recent interest, yet individual studies are not advancing a more general, predictive ecology. Significant progress will be facilitated by adopting a coherent theoretical framework comprised of three elements: an underlying trait distribution, a performance filter defining the fitness of traits in different environments, and a dynamic projection of the performance filter along some environmental gradient. This framework allows changes in the trait distribution and associated modifications to community composition or ecosystem function to be predicted across time or space. The structure and dynamics of the performance filter specify two key criteria by which we judge appropriate quantitative methods for testing traits-based hypotheses. Bayesian multilevel models, dynamical systems models and hybrid approaches meet both these criteria and have the potential to meaningfully advance traits-based ecology. [source] Global constraints on rural fishing communities: whose resilience is it anyway?FISH AND FISHERIES, Issue 1 2007Martin D Robards Abstract Sustaining natural resources is regarded as an important component of ecological resilience and commonly assumed to be of similar importance to social and economic vitality for resource-dependent communities. However, communities may be prevented from benefiting from healthy local resources due to constrained economic or political opportunities. In the case of Alaskan wild salmon, the fisheries are in crisis due to declining economic revenues driven by the proliferation of reliable and increasingly high-quality products from fish farms around the world. This stands in contrast with many of the world's wild-capture fisheries where diminished biological abundance has led to fishery collapse. Furthermore, increasing efficiency of salmon farm production, globalization, and dynamic consumer preferences, suggests that the wild salmon industry will continue to be challenged by the adaptability, price and quality of farmed salmon. Conventional responses to reduced revenues by the wild-capture industry have been to increase economic efficiency through implementing a range of entry entitlement and quota allocation schemes. However, while these mechanisms may improve economic efficiency at a broad scale, they may not benefit local community interests, and in Alaska have precipitated declines in local ownership of the fishery. To be viable, economic efficiency remains a relevant consideration, but in a directionally changing environment (biological, social or economic), communities unable to procure livelihoods from their local resources (through access or value) are likely to seek alternative economic opportunities. The adopted strategies, although logical for communities seeking viability through transformation in a changing world, may not be conducive to resilience of a ,fishing community' or the sustainability of their wild fish resources. We use a theoretically grounded systems approach and data from Alaska's Bristol Bay salmon fishery to demonstrate feedbacks between global preferences towards salmon and the trade-offs inherent when managing for the resilience of wild salmon populations and human communities at different scales. [source] MOVING BEYOND BIOPOWER: HARDT AND NEGRI'S POST-FOUCAULDIAN SPECULATIVE PHILOSOPHY OF HISTORYHISTORY AND THEORY, Issue 4 2005RÉAL FILLION ABSTRACT I argue in this paper that the attempt by Michael Hardt and Antonio Negri in Empire and Multitude to "theorize empire" should be read both against the backdrop of speculative philosophy of history and as a development of the conception of a "principle of intelligibility" as this is discussed in Michel Foucault's recently published courses at the Collège de France. I also argue that Foucault's work in these courses (and elsewhere) can be read as implicitly providing what I call "prolegomena to any future speculative philosophy of history." I define the latter as concerned with the intelligibility of the historical process considered as a whole. I further suggest, through a brief discussion of the classical figures of Kant, Hegel, and Marx, that the basic features of speculative philosophy of history concern the articulation of both the telos and dynamics of history. My claim is that Hardt and Negri provide an account of the telos and dynamics of history that respects the strictures imposed on speculative philosophy of history by Foucault's work, and thus can be considered as providing a post-Foucauldian speculative philosophy of history. In doing so, they provide a challenge to other "theoretical" attempts to account for our changing world. [source] Beyond biological control: non-pest insects and their pathogens in a changing worldINSECT CONSERVATION AND DIVERSITY, Issue 2 2009HELEN E. ROY Abstract. 1Over the last few decades, there have been considerable advances in the fields of insect pathology and insect conservation but the two disciplines rarely meet. The potential of entomopathogens as biological control agents of pest insects is widely recognised but information on the role of pathogens in insect population regulation, more generally, is limited. For example, the role of pathogens as natural enemies of non-pest insects, including those of conservation value, is seldom considered beyond their context as ,non-targets' of microbial control agents. 2Entomopathogens are prevalent in natural systems and should receive greater attention in life-history studies. There is no doubt that viruses, bacteria and fungi are major mortality agents of insects but their significance tends to be overshadowed by the attention given to predators and parasitoids. 3We highlight the critical function that entomopathogens could have in insect population dynamics with particular reference fragmented habitats as illustrated by the theoretical literature. However, we emphasise that there are few empirical studies to test theoretical predictions. 4We suggest that since an increase in the incidence of disease is predicted in most environmental change scenarios, it is more important than ever to turn our attention to insect pathology when we consider insect population dynamics. [source] A concept analysis of renal supportive care: the changing world of nephrologyJOURNAL OF ADVANCED NURSING, Issue 6 2007Helen Noble Abstract Title.,A concept analysis of renal supportive care: the changing world of nephrology Aim., This paper is a report of a concept analysis of renal supportive care. Background., Approximately 1·5 million people worldwide are kept alive by renal dialysis. As services are required to support patients who decide not to start or to withdraw from dialysis, the term renal supportive care is emerging. Being similar to the terms palliative care, end-of-life care, terminal care and conservative management, there is a need for conceptual clarity. Method., Rodgers' evolutionary method was used as the organizing framework for this concept analysis. Data were collected from a review of CINAHL, Medline, PsycINFO, British Nursing Index, International Bibliography of the Social Sciences and ASSIA (1806,2006) using, ,renal' and ,supportive care' as keywords. All articles with an abstract were considered. The World Wide Web was also searched in English utilizing the phrase ,renal supportive care'. Results., Five attributes of renal supportive care were identified: available from diagnosis to death with an emphasis on honesty regarding prognosis and impact of disease; interdisciplinary approach to care; restorative care; family and carer support and effective, lucid communication to ensure informed choice and clear lines of decision-making. Conclusion., Renal supportive care is a dynamic and emerging concept relevant, but not limited to, the end phase of life. It suggests a central philosophy underpinning renal service development that allows patients, carers and the multidisciplinary team time to work together to realize complex goals. It has relevance for the renal community and is likely to be integrated increasingly into everyday nephrology practice. [source] REVIEW: The identification of priority policy options for UK nature conservationJOURNAL OF APPLIED ECOLOGY, Issue 5 2010William J. Sutherland Summary 1.,The conservation of biodiversity depends upon both policy and regulatory frameworks. Here, we identify priority policy developments that would support conservation in the UK in the light of technological developments, changes in knowledge or environmental change. 2.,A team of seven representatives from governmental organizations, 17 from non-governmental organizations and six academics provided an assessment of the priority issues. The representatives consulted widely and identified a long-list of 117 issues. 3.,Following voting and discussion during a 2-day meeting, these were reduced to a final list of 25 issues and their potential policy options and research needs were identified. Many of the policies related to recent changes in approaches to conservation, such as increased interest in ecosystem services, adaptation to climate change and landscape ecology. 4.,We anticipate that this paper will be useful for policy makers, nature conservation delivery agencies, the research community and conservation policy advocates. 5.,Although many of the options have global significance, we suggest that other countries consider an equivalent exercise. We recommend that such an exercise be carried out in the UK at regular intervals, say every 5 years, to explore how biodiversity conservation can best be supported by linked policy development and research in a changing world. 6.,Synthesis and applications. Opportunities for policy development were prioritized and for each of the top 25 we identified the current context, policy options and research questions. These largely addressed new issues relating to developing topics such as ecosystem services, landscape planning and nanotechnology. We envisage that this will largely be used by researchers wishing to make a contribution to potential policy debates. [source] Priority research areas for ecosystem services in a changing worldJOURNAL OF APPLIED ECOLOGY, Issue 6 2009Emily Nicholson Summary 1.,Ecosystem services are the benefits humans obtain from ecosystems. The importance of research into ecosystem services has been widely recognized, and rapid progress is being made. However, the prevailing approach to quantifying ecosystem services is still based on static analyses and single services, ignoring system dynamics, uncertainty and feedbacks. This is not only partly due to a lack of mechanistic understanding of processes and a dearth of empirical data, but also due to a failure to engage fully with the interdisciplinarity of the problem. 2.,We argue that there is a tendency to ignore the feedbacks between and within both social and ecological systems, and a lack of explicit consideration of uncertainty. Metrics need to be developed that can predict thresholds, which requires strong linkages to underlying processes, while the development of policy for management of ecosystem services needs to be based on a broader understanding of value and drivers of human well-being. 3.,We highlight the complexities, gaps in current knowledge and research, and the potentially promising avenues for future investigation in four priority research areas: agendas, processes, metrics and uncertainty. 4.,Synthesis and applications. The research interest in the field of ecosystem services is rapidly expanding, and can contribute significantly to the sustainable management of natural resources. However, a narrow disciplinary approach, or an approach which does not consider feedbacks within and between ecological and social systems, has the potential to produce dangerously misleading policy recommendations. In contrast, if we explicitly acknowledge and address uncertainties and complexities in the provision of ecosystem services, progress may appear slower but our models will be substantially more robust and informative about the effects of environmental change. [source] The transmission mechanism in a changing worldJOURNAL OF APPLIED ECONOMETRICS, Issue 1 2007Michael Artis The paper aims to identify those factors that cause changes in the speed and strength of the international transmission of output shocks from the USA to specified European economies. These factors are identified through the use of generalized impulse response functions conditioned on histories defined by an abrupt transition VAR. The chosen transition variables comprise changes in exchange rates, financial prices, international capital flows, trade links and monetary policy instruments. Besides the identification of asymmetric responses, the proposed model is useful in analyzing the strong effect of the recent US recession on the European economies and changes in business cycle synchronization over time.

[source] Generational differences: revisiting generational work values for the new millenniumJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 4 2002Karen Wey Smola As we enter the new millennium and face the entrance of another generation of workers into the changing world of work, managers are encouraged to deal with the generational differences that appear to exist among workers. This paper revisits the issue of generational differences and the causes of those differences. Data were obtained from more than 350 individuals across the country who responded to a request to complete a survey. Current generational differences in worker values are analysed and the results are compared to a similar study conducted in 1974. Results suggest that generational work values do differ. To a lesser degree, the results suggest that work values also change as workers grow older. Finally, the results indicate an increasing desire among American workers to balance work and personal goals. This change in attitude was reflected even within the same cohort group.

[source] Interaction for lifelong learningBRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 6 2004Norm Friesen The term ,lifelong', as applied to education or learning, has been in circulation for more than a quarter of a century. It has played an important role in policy discussions, as well as in studies of the sociology and economics of education. The relationship of this term to the rapidly changing world of information and educational technologies, and to the various conceptions of interaction that are central to these technologies, however, has been considered much less frequently. This paper seeks to shed light on the relationship between lifelong learning and the interactive technologies that have become associated specifically with the Semantic Web. It begins by presenting a fictional narrative to illustrate a lifelong learning scenario in the context of the services and resources that the Semantic Web will be capable of providing. It then proceeds to isolate a number of general characteristics of lifelong learning as they are manifest in this scenario and in recent literature on the subject. The paper then explores how emergent, interactive technologies of the Semantic Web have the general potential to address many of the characteristics of lifelong learning, and hold out the promise of satisfying a wide variety of lifelong learning needs. It will conclude by considering some of the outstanding challenges presented by lifelong learning contexts, and mention some of the limitations of advanced technologies used to address these needs.
