Historical Approach (historical + approach)
Selected AbstractsThe dietetic treatment of obesityPRACTICAL DIABETES INTERNATIONAL (INCORPORATING CARDIABETES), Issue 9 2001Alison H. Beattie BSc Hons, SRD Senior Dietitian Abstract Obesity has a direct, proportional link to morbidity and mortality, and despite the proven medical benefits of weight loss treatment failure rates are high. Historical approaches to weight management within the health service have focused solely on dietary issues. It is now widely accepted that dietary advice given in isolation is ineffective in inducing and sustaining significant weight loss. Obesity is a complex, multifactorial disease and any successful weight management programme should provide tailored dietary advice and facilitate permanent behavioural and lifestyle change. In addition, realistic goals (10% body weight loss) should be recommended. Exercise and physical activity suggested should be geared to individual capabilities. This article addresses how dietitians are treating obesity and what factors other than traditional diet sheets are essential components of a weight management programme.

[source] The ,Neoliberal Turn' and the New Social Policy in Latin America: How Neoliberal, How New?DEVELOPMENT AND CHANGE, Issue 5 2008Maxine Molyneux ABSTRACT The term neoliberal is widely used as shorthand to describe the policy environment of the last three decades. Yet the experience of the Latin American region suggests that it is too broad a descriptor for what is in fact a sequenced, fragmented and politically indeterminate process. This article examines the evolution of social protection in the region, and argues for a more grounded, historical approach to neoliberalism, and for some analytic refinement to capture the different ,moments' in its policy evolution, its variant regional modalities, and its co-existence with earlier policies and institutional forms. It suggests that totalizing conceptions of neoliberalism as imposing an inexorable market logic with predetermined social and political outcomes fail to capture the variant modalities, adaptations and indeed resistance to the global diffusion of the structural reforms. This article outlines the systems of social welfare prevailing in Latin America prior to the reforms, and then examines the principle elements of what has been termed the ,New Social Policy' in Latin America, engaging three issues: the periodization of neoliberalism; the role of the state; and the place of politics in the neoliberal reform agenda. [source] Constructing Vulnerability: The Historical, Natural and Social Generation of Flooding in Metropolitan ManilaDISASTERS, Issue 3 2003Greg Bankoff Flooding is not a recent hazard in the Philippines but one that has occurred throughout the recorded history of the archipelago. On the one hand, it is related to a wider global ecological crisis to do with climatic change and rising sea levels but on the other hand, it is also the effect of more localised human activities. A whole range of socio-economic factors such as land use practices, living standards and policy responses are increasingly influencing the frequency of natural hazards such as floods and the corresponding occurrence of disasters. In particular, the reason why flooding has come to pose such a pervasive risk to the residents of metropolitan Manila has its basis in a complex mix of inter-relating factors that emphasise how the nature of vulnerability is constructed through the lack of mutuality between environment and human activity over time. This paper examines three aspects of this flooding: first, the importance of an historical approach in understanding how hazards are generated; second, the degree of interplay between environment and society in creating risk; and third, the manner in which vulnerability is a complex construction. [source] An analysis of the demarcation problem in science and its application to therapeutic touch theoryINTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 6 2007David Newbold RN PhD This paper analyses the demarcation problem from the perspective of four philosophers: Popper, Kuhn, Lakatos and Feyerabend. To Popper, pseudoscience uses induction to generate theories, and only performs experiments to seek to verify them. To Popper, falsifiability is what determines the scientific status of a theory. Taking a historical approach, Kuhn observed that scientists did not follow Popper's rule, and might ignore falsifying data, unless overwhelming. To Kuhn, puzzle-solving within a paradigm is science. Lakatos attempted to resolve this debate, by suggesting history shows that science occurs in research programmes, competing according to how progressive they are. The leading idea of a programme could evolve, driven by its heuristic to make predictions that can be supported by evidence. Feyerabend claimed that Lakatos was selective in his examples, and the whole history of science shows there is no universal rule of scientific method, and imposing one on the scientific community impedes progress. These positions are used in turn, to examine the scientific status of therapeutic touch theory. The paper concludes that imposing a single rule of method can impede progress, in the face of multiple epistemologies, and the choice of scientific approach should be a pragmatic one based on the aims of the programme. [source] Language, history and the nation: an historical approach to evaluating language and cultural claimsNATIONS AND NATIONALISM, Issue 2 2008VICKI SPENCER ABSTRACT. In contrast to the abstract commitment to individual rights found in liberal critics of Bill 101 and the equally ahistorical approach of multicultural theorists like Bhikhu Parekh, this paper proposes that the particular historical circumstances surrounding the current minority status of different groups is crucial in evaluating the legitimacy of one cultural group to promote its cultural needs over another group within existing states. When the culture of a group residing within a particular state is secure in a neighbouring jurisdiction, the issue at stake is not necessarily the survival of a unique culture but the cultural needs of particular individuals. It does not follow that they have no legitimate claims against the state. However, in examining the language policies in Quebec and the newly independent Baltic states, it is argued that they are different in kind to the rights due to long-standing communities struggling for linguistic survival. [source] The Limits of Rational Choice: New Institutionalism in the Test Bed of Central Banking Politics in AustraliaPOLITICAL STUDIES, Issue 3 2002Stephen Bell This paper tests the explanatory capacities of different versions of new institutionalism by examining the Australian case of a general transition in central banking practice and monetary politics: namely, the increased emphasis on low inflation and central bank independence. Standard versions of rational choice institutionalism largely dominate the literature on the politics of central banking, but this approach (here termed RC1) fails to account for Australian empirics. RC1 has a tendency to establish actor preferences exogenously to the analysis; actors'motives are also assumed a priori; actor's preferences are depicted in relatively static, ahistorical terms. And there is the tendency, even a methodological requirement, to assume relatively simple motives and preference sets among actors, in part because of the game theoretic nature of RC1 reasoning. It is possible to build a more accurate rational choice model by re-specifying and essentially updating the context, incentives and choice sets that have driven rational choice in this case. Enter RC2. However, this move subtly introduces methodological shifts and new theoretical challenges. By contrast, historical institutionalism uses an inductive methodology. Compared with deduction, it is arguably better able to deal with complexity and nuance. It also utilises a dynamic, historical approach, and specifies (dynamically) endogenous preference formation by interpretive actors. Historical institutionalism is also able to more easily incorporate a wider set of key explanatory variables and incorporate wider social aggregates. Hence, it is argued that historical institutionalism is the preferred explanatory theory and methodology in this case. [source] Future eating and country keeping: what role has environmental history in the management of biodiversity?JOURNAL OF BIOGEOGRAPHY, Issue 5 2001D.M.J.S. Bowman In order to understand and moderate the effects of the accelerating rate of global environmental change land managers and ecologists must not only think beyond their local environment but also put their problems into a historical context. It is intuitively obvious that historians should be natural allies of ecologists and land managers as they struggle to maintain biodiversity and landscape health. Indeed, ,environmental history' is an emerging field where the previously disparate intellectual traditions of ecology and history intersect to create a new and fundamentally interdisciplinary field of inquiry. Environmental history is rapidly becoming an important field displacing many older environmentally focused academic disciplines as well as capturing the public imagination. By drawing on Australian experience I explore the role of ,environmental history' in managing biodiversity. First I consider some of the similarities and differences of the ecological and historical approaches to the history of the environment. Then I review two central questions in Australian environment history: landscape-scale changes in woody vegetation cover since European settlement and the extinction of the marsupials in both historical and pre-historical time. These case studies demonstrate that environmental historians can reach conflicting interpretations despite using essentially the same data. The popular success of some environmental histories hinges on the fact that they narrate a compelling story concerning human relationships and human value judgements about landscape change. Ecologists must learn to harness the power of environmental history narratives to bolster land management practices designed to conserve biological heritage. They can do this by using various currently popular environmental histories as a point of departure for future research, for instance by testing the veracity of competing interpretations of landscape-scale change in woody vegetation cover. They also need to learn how to write parables that communicate their research findings to land managers and the general public. However, no matter how sociologically or psychologically satisfying a particular environmental historical narrative might be, it must be willing to be superseded with new stories that incorporate the latest research discoveries and that reflects changing social values of nature. It is contrary to a rational and publicly acceptable approach to land management to read a particular story as revealing the absolute truth. [source] Gene trees: A powerful tool for exploring the evolutionary biology of species and speciationPLANT SPECIES BIOLOGY, Issue 3 2000Alan R. Templeton Abstract Evolutionary trees can be constructed from the haplotypes observed with molecular surveys of sequence or restriction site variation. Such gene trees can be constructed regardless of whether or not all of the individual specimens came from one or many species. Hence, these gene trees can straddle the species/population interface, thereby providing a powerful tool for studying the meaning of species and the process of speciation. We illustrate how historical approaches using gene trees can be used to separate the effects of population structure from population history, in order to rigorously test the species status of a group, and to test hypotheses about the process of speciation. A worked example of species status in the Piriqueta caroliniana complex is presented. Species status is evaluated under the cohesion species concept that defines a species as an evolutionary lineage with boundaries arising from the forces that create reproductive communities. Such forces are collectively called cohesion mechanisms and consist of two main subtypes: (i) genetic exchangeability, and (ii) ecological interchangeability. To make this definition operational, populations that behave as separate evolutionary lineages are first identified. A method is reviewed for inferring lineages using explicit statistical criteria from geographic overlays upon gene trees. Once lineages have been identified, the next step is to use the cohesion mechanisms to identify candidate traits that should contribute to genetic exchangeability and/or ecological interchangeability. The cohesion species are then identified by performing overlays upon gene trees in order to identify significant transitions in the candidate traits. Cohesion species are recognized only when statistically significant reproductive/ecological transitions occur that are concordant with the lineages defined earlier. This data-rich method of recognizing species automatically generates much information about the biogeography, population structure, historical events, and ecology and/or reproductive biology of the group under study. In turn, this information provides much insight into the process of speciation. It also makes the criteria, data, methods of analysis and degree of support for the species inference completely explicit, thereby avoiding confusion, inconsistency and artificial controversies that plague much of the literature on species concepts. [source] Improving assessments of marine protected areasAQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 2 2010Joachim Claudet Abstract 1.The use of experimental design and statistical analysis to evaluate the effects of marine protected areas (MPAs) is increasingly popular throughout the world. 2.However, in looking at historical approaches to MPA evaluations, flaws were identified in the execution of theoretically correct designs, as well as disconnects between the stated objectives of MPAs and those of assessment studies. 3.MPA assessments can be improved by: (1) considering the enforcement/compliance level; (2) linking explicitly the choice of indicator(s) to the MPA objectives; (3) accounting for habitat structure; (4) taking into account the age and size of the MPA; and (5) quantifying the fishing pressure outside the MPA (including possible displacement effects). 4.Neglecting social factors, using inappropriate indicators, and/or ignoring relevant covariates, carries the risk of having MPAs dismissed as an effective management tool. Societal expectations are strong that MPAs will confer benefits, and thus assessment studies need to be progressively improved using new methodologies and the best available scientific evidence.

[source] Psychiatric diagnoses in the context of genetic studies of bipolar disorderBIPOLAR DISORDERS, Issue 6 2001Anne Duffy Precise definition of the phenotype is an issue of critical importance for the future success of genetic studies of bipolar disorders. So far, an uncertain phenotypic spectrum and genetic heterogeneity are realities that have hampered progress in genetic studies. While recognition of a broader spectrum of related illnesses is important for some applications, for genetic studies a narrow spectrum of illness closely tied to the genotype is paramount. This paper highlights current dilemmas and trends associated with phenotype specification and traces historical approaches. Finally, we explore a number of strategic directions in the diagnostic approach to bipolar disorders that may better serve genetic studies. [source] |
