Heuristic Value (heuristic + value)
Selected AbstractsKNOWING THE SELF AND KNOWING THE "OTHER": THE EPISTEMOLOGICAL AND HEURISTIC VALUE OF THE YIJINGJOURNAL OF CHINESE PHILOSOPHY, Issue 4 2006RICHARD J. SMITHArticle first published online: 8 NOV 200 [source] On phenomenology and classification of hoarding: a reviewACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2004T. Maier Objective:, Hoarding is a behavioural abnormity characterized by the excessive collection of poorly useable objects. It is described mainly in association with obsessive,compulsive disorders (OCDs) and in geriatric populations. Yet the literature on the phenomenon is heterogeneous and the notion obviously lacks a consistent definition. This review attempts to describe the psychopathological and clinical spectrum of hoarding and may contribute to clarify its classification. Method:, Systematic review and discussion of the literature on hoarding. Results:, Hoarding is a complex behavioural phenomenon associated with different mental disorders. The psychopathological structure is variously composed of elements of OCDs, impulse-control disorders, and ritualistic behaviour. Severe self-neglect is a possible consequence of hoarding. Conclusion:, Without further specifications the term hoarding is of limited heuristic value and cannot guide therapeutic interventions satisfactorily. The condition needs to be evaluated carefully in every particular case in relation to the aforementioned psychopathological concepts. [source] The Concept that Came Out of the Cold: the Progressive Historicization of Generic Fascism and its New Relevance to Teaching Twentieth-century HistoryHISTORY COMPASS (ELECTRONIC), Issue 1 2003Roger Griffin This article first surveys the confusion that prevailed in fascist studies for decades, and which makes it quite understandable if the term ,fascism' has been generally avoided both by historians and by lecturers and others teaching inter-war European history to students in non-specialist ,survey' courses. It then outlines the main features of the ,new consensus' that is emerging among scholars on the heuristic value of seeing fascism as a form of revolutionary ideology, bent on purging society of decadence and inaugurating the rebirth of the nation. Next, it focuses on how this approach enables Fascism and Nazism to be located within the supranational forces shaping modern history, and on the light it throws on their profound relationship to totalitarianism, political religion and modernity. It closes with brief examples of how this approach can be applied to structuring answers to essays and exam questions on inter-war Europe, and welcomes the prospect opened up by the new consensus for greater collaboration between specialists in fascist studies, empirical historians, university lecturers, textbook writers and students , and even, one day, students in secondary education, and their teachers and examiners , in this fascinating, and rapidly evolving, field of teaching and research. [source] Refining the stress-gradient hypothesis for competition and facilitation in plant communitiesJOURNAL OF ECOLOGY, Issue 2 2009Fernando T. Maestre Summary 1The stress-gradient hypothesis (SGH) predicts that the frequency of facilitative and competitive interactions will vary inversely across abiotic stress gradients, with facilitation being more common in conditions of high abiotic stress relative to more benign abiotic conditions. With notable exceptions, most tests of the SGH have studied the interaction between a single pair or a few pairs of species, and thus have evaluated shifts in the magnitude and direction of pair-wise interactions along stress gradients, rather than shifts in the general frequency of interactions. 2The SGH has been supported by numerous studies in many ecosystems, has provided a crucial foundation for studying the interplay between facilitation and competition in plant communities, and has a high heuristic value. However, recent empirical research indicates that factors like the variation among species and the nature of the stress gradient studied add complexity not considered in the SGH, creating an opportunity to extend the SGH's general conceptual framework. 3We suggest that one approach for extending the SGH framework is to differentiate between the original idea of how ,common' interactions might be along stress gradients and the ubiquitous empirical approach of studying shifts in the strength of pair-wise interactions. Furthermore, by explicitly considering the life history of the interacting species (relative tolerance to stress vs. competitive ability) and the characteristics of the stress factor (resource vs. non-resource) we may be able to greatly refine specific predictions relevant to the SGH. 4We propose that the general pattern predicted by the SGH would hold more frequently for some combinations of life histories and stress factor, particularly when the benefactor and beneficiary species are mostly competitive and stress-tolerant, respectively. However, we also predict that other combinations are likely to yield different results. For example, the effect of neighbours can be negative at both ends of the stress gradient when both interacting species have similar ,competitive' or ,stress-tolerant' life histories and the abiotic stress gradient is driven by a resource (e.g. water). 5Synthesis. The extension of the SGH presented here provides specific and testable hypotheses to foster research and helps to reconcile potential discrepancies among previous studies. It represents an important step in incorporating the complexity and species-specificity of potential outcomes into models and theories addressing how plant,plant interactions change along stress gradients. [source] Evolution of the distribution of dispersal distance under distance-dependent cost of dispersalJOURNAL OF EVOLUTIONARY BIOLOGY, Issue 4 2002F. Rousset Abstract We analyse the evolution of the distribution of dispersal distances in a stable and homogeneous environment in one- and two-dimensional habitats. In this model, dispersal evolves to avoid the competition between relatives although some cost might be associated with this behaviour. The evolutionarily stable dispersal distribution is characterized by an equilibration of the fitness gains among all the different dispersal distances. This cost-benefit argument has heuristic value and facilitates the comprehension of results obtained numerically. In particular, it explains why some minimal or maximal probability of dispersal may evolve at intermediate distances when the cost of dispersal function is an increasing function of distance. We also show that kin selection may favour long range dispersal even if the survival cost of dispersal is very high, provided the survival probability does not vanish at long distances. [source] A heuristic blunder: Notes on an ethnographic situation in southwest ChinaASIA PACIFIC VIEWPOINT, Issue 2 2010Stéphane Gros Abstract During long-term fieldwork the increasing involvement of the ethnographer in the lives of others raises a series of methodological and ethical issues. These can become even more pronounced when one is working with ethnic minorities in a socialist country. Yet, a seldom acknowledged reality of ethnographic fieldwork experience are the ,little failures' that occur along the way, alongside ethnographic blunders. I argue that these are difficult to avoid and can be part of an important learning process, oftentimes for both researcher and researched. Through the detailed description of a blunder that the author made during his research in southwest China with members of the Drung ethnic minority, this article advocates for the heuristic value of such mishaps, suggesting that one can learn a lot from accidents and unexpected events while undertaking in-depth ethnographic fieldwork. In this case, this helped to shed light on the micropolitics of Drung village life in southwest Yunnan, and the place of a ,minority nationality' in wider Chinese society. [source] Die Fotografie , ein neues Bildmedium im Wissenschaftspanorama des 19.BERICHTE ZUR WISSENSCHAFTSGESCHICHTE, Issue 2 2005Jahrhunderts. Abstract Photography , a novel medium of scientific representation in the XIXth century array of arts and sciences. To delve into various nineteenth century academic disciplines under the heading ,photography in the arts and sciences' as did last year's annual conference of the History of Science Society , the interest in such a topic only partly stems from the ,iconic turn' that has generally enlarged the scope of the social sciences in recent years. A more poignant feature in any such present day study will probably be a basic scepticism facing the fact that in public use photographs have been manipulated in many respects. Yet, while shying away from any simple success story, a historically minded approach to changing ,visual paradigms' (Historische Bildwissenschaft) has begun to emerge. In this context, it has proved of considerable heuristic value to reconsider the role of early photography in an array of science, arts and technology: Since the reliance on the traditional ways of sketching reality persisted, in many an instance where photography was introduced, the thoughts the pioneer photographers had about their new, seemingly automated business, call for close attention. Thus scholarship sets up a parallel ,discussion room'; the lively debate on the benefit of academic drawings as opposed to photographic portraits is a case in point. Some fairly specialised reports on photographically based analyses, such as electron microscopy, point to a borderline where the very idea of representation as a correspondence of reality and imagination gets blurred. Even though any ,visual culture' will have to shoulder the ,burden of representation', it is equally likely that it will offer a deeper sensibility for the intricacies entailed in the variegated ways of illustrating or mapping chosen subjects of scientific interest. Scholarship may thus somewhat control the disillusionment that by now has become the epitome of writing on photographic history. Provided with a renewed methodological awareness for the perception process and its photographic transition, historians may strike a better balance between the ever present tendencies of a realistic and an aesthetic way of picturing the world we live in. [source] A Promising Psychosocial Intervention: Next Steps Include Systematic Study and Creative ExtensionCLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 2 2004Cheryl A. King Sloan and Marx (this issue) provide a comprehensive and thoughtful review of the written exposure paradigm, noting that it is a promising psychosocial intervention. They focus on possible explanatory theories and close their review by advocating for research aimed at understanding mechanisms of action. While this critically important research is being conducted by some investigators, it will be important for others to consider modifications or enhancements that might improve the efficacy and effectiveness of the written exposure paradigm and still others to consider the myriad of related intervention possibilities raised by the promising findings. That is, the emerging data on the written exposure paradigm have substantial heuristic value. There is insufficient psychosocial intervention research being conducted, and we have barely scratched the surface of possibilities related to this strategy. [source] | |||||||||||||
