Selected AbstractsDefining sustainability: a conceptual orientationJOURNAL OF CHEMICAL TECHNOLOGY & BIOTECHNOLOGY, Issue 4 2007Robert O. Vos Abstract Despite the ubiquity of the concept of sustainability, defining the term and construing meaning for different contexts is difficult. This paper presents several archetypes of sustainability that are useful for classifying and understanding existing definitions. Definitions that emphasize one part or another of the core concept of sustainability will be necessary at varying scales and in different contexts. This paper presents a conceptual guide that contrasts a dominant paradigm of economic growth and development with ,thick' and ,thin' versions of sustainability. Definitions of sustainability are explored in terms of their orientation to the ontology of nature, substitutability of resources, economic growth, population growth, role of technology, and social equity.

However, although many researchers have embraced the theoretical strength of situated learning theory, conceptual issues remain undeveloped in the literature. Roberts, for example, argues in this issue that the notion of ,communities of practice', a core concept in situated learning theory , is itself problematic. To complement her discussion, this paper explores the communities of practice concept from several perspectives. Firstly, we consider the perspective of the individual learner, and examine the processes which constitute ,situated learning'. Secondly, we consider the broader socio-cultural context in which communities of practice are embedded. We argue that the cultural richness of this broader context generates a fluidity and heterogeneity within and beyond communities. Finally, we argue that it is sometimes difficult to distinguish conceptually between the terms ,participation' and ,practice' because of occasional duplication of meaning. We propose, instead, a refinement of the definition to allow for greater conceptual clarity. [source] Factor Structure and Concurrent Validity of the Obsessive Compulsive Drinking Scale in a Group of Alcohol-Dependent Subjects of Mexico CityALCOHOLISM, Issue 7 2009Marta Cordero Background:, Obsessive thoughts and compulsive drinking behaviors have been proposed as key factors associated with the loss of control over alcohol consumption experienced by alcohol-dependent patients. The self-report 14-item Obsessive Compulsive Drinking Scale (OCDS; Anton et al., 1995) was designed in order to rate these features. Methods:, A Spanish-translated version of the OCDS was applied to a group of 159 alcohol-dependent subjects while in abstinence, and data were analyzed in order to evaluate the factor structure and concurrent validity of the scale. Results:, Several solutions were explored after applying the principal factor analysis to the data. The most plausible result was obtained after excluding the items on quantity and frequency of drinking. This model explaining 56.9% of the variance included 2 factors: obsessive thoughts related to drinking and interference/behaviors related to drinking. Additionally, OCDS scores were significantly correlated with measures for the Alcohol Dependence Scale, number of DSM-IV criteria met for alcohol dependence as well as the number of days in a week engaged in heavy drinking, indicating concurrent validity. Conclusions:, Our results support the use of OCDS as a valid self-rated instrument that can be broadly applied in research and treatment settings. However, its current version includes questions that may not represent the core concept of craving. The abridged 12-item version of the scale (excluding the items on drinking habits) maintains good psychometrics features and seems to be adequate when different cognitive and behavioral dimensions are explored. [source] Parents' leisure: the impact of raising a child with down syndromeOCCUPATIONAL THERAPY INTERNATIONAL, Issue 3 2005Deborah O'Mullan Wayne MS Abstract A healthy and productive life depends upon the balance between work, leisure, and activities of daily living. Gaining or regaining that balance is a core concept within occupational therapy. Raising a child with special needs is one factor that challenges parents in achieving a balance. The purpose of this research was to describe factors that affect the leisure occupations of these parents. A qualitative approach was used in which in-depth interviews and the adapted Barth Time Construction were administered to four married couples that were raising children with Down syndrome who were between seven and nine years of age. Data was examined through content analysis. Results indicated that the parents of children with Down syndrome had limitations in time available for leisure, changes in types of leisure engaged in, and an increase in planning for leisure activities. Despite overall satisfaction with the manner in which they allocated their time, parents frequently noted the potential benefits of incorporating more leisure into their daily lives. Limitations of the study include type and size of sample. Copyright © 2005 John Wiley & Sons, Ltd. [source] Occupational therapy and early intervention: a family-centred approachOCCUPATIONAL THERAPY INTERNATIONAL, Issue 4 2003Margaret A. Edwards Abstract The purpose of this study was to identify factors that encourage or inhibit family-centred practice in the occupational therapy intervention process. A qualitative paradigm using grounded theory methodology was utilized to gather and analyse data. Participants included six families and four occupational therapists. Data analysis from the family interviews identified six categories: education, communication, relationship, parental roles, follow through, and scheduling. With further analysis two central themes of time and support were extracted from these categories. Analysis of the occupational therapists' interviews revealed six categories: education, communication, relationship, sibling/family participation, follow through, and empowerment. The central themes emerging from these categories are time and natural routine. The themes obtained from the families and occupational therapists were then compared and family individuality was identified as the core concept. Viewing families as a unique entity is necessary to assist occupational therapists in providing the most effective family-centred occupational therapy. Copyright © 2003 Whurr Publishers Ltd. [source] Environmental Obligations and the Limits of Transnational CitizenshipPOLITICAL STUDIES, Issue 2 2009Andrew Mason Notions of cosmopolitan and environmental citizenship have emerged in response to concerns about environmental sustainability and global inequality. But even if there are obligations of egalitarian justice that extend across state boundaries, or obligations of environmental justice to use resources in a sustainable way that are owed to those beyond our borders, it is far from clear that these are best conceptualised as obligations of global or environmental citizenship. Through identifying a core concept of citizenship, I suggest that citizenship obligations are, by their nature, owed (at least in part) in virtue of other aspects of one's common citizenship, and that obligations of justice, even when they arise as a result of interconnectedness or past interactions, are not best conceived as obligations of citizenship in the absence of some other bond that unites the parties. Without ruling out the possibility of beneficial conceptual change, I argue that Andrew Dobson's model of ecological citizenship is flawed because there is no good reason to regard the obligations of environmental justice which it identifies as obligations of ecological citizenship, and that other models of cosmopolitan or global citizenship face a similar objection. [source] Unmet Need for Family Planning in Developing Countries and Implications for Population PolicyPOPULATION AND DEVELOPMENT REVIEW, Issue 4 2000John B. Casterline Unmet need for family planning has been a core concept in international population discourse for several decades. This article reviews the history of unmet need and the development of increasingly refined methods of its empirical measurement and delineates the main questions that have been raised about unmet need during the past decade, some of which concern the validity of the concept and others its role in policy debates. The discussion draws heavily on empirical research conducted during the 1990s, much of it localized, in-depth studies combining quantitative and qualitative methodologies. Of the causes of unmet need other than those related to access to services, three emerge as especially salient: lack of necessary knowledge about contraceptive methods, social opposition to their use, and health concerns about possible side effects. The article argues that the concept of unmet need for family planning, by joining together contraceptive behavior and fertility preferences, encourages an integration of family planning programs and broader development approaches to population policy. By focusing on the fulfillment of individual aspirations, unmet need remains a defensible rationale for the formulation of population policy and a sensible guide to the design of family planning programs. [source] Technology, Place, and the Nonmodern ThesisJOURNAL OF ARCHITECTURAL EDUCATION, Issue 3 2001Steven A. Moore Proposals for regionalist architecture have appeared regularly in architectural discourse since the seventeenth century. Central to this discourse are shifting attitudes toward the core concepts of technology and place. Moderns, it seems, tend to value technology and devalue place. Postmoderns do the opposite - they value place and devalue technology. The doctrines of critical regionalism defy categorization because they value both technology and place positively. However, by deriving its program equally from the modern assumptions of Jurgen Habermas and from the postmodern assumption of Martin Heidegger, critical regionalism presents a philosophical antinomy, or unresolvable conflict. It is this conflict that suggests a nonmodern thesis for architecture. [source] Alasdair MacIntyre on Education: In Dialogue with Joseph DunneJOURNAL OF PHILOSOPHY OF EDUCATION, Issue 1 2002Alasdair Macintyre This discussion begins from the dilemma, posed in some earlier writing by Alasdair MacIntyre, that education is essential but also, in current economic and cultural conditions, impossible. The potential for resolving this dilemma through appeal to ,practice', ,narrative unity', and ,tradition'(three core concepts in After Virtue and later writings) is then examined. The discussion also explores the relationship of education to the modern state and the power of a liberal education to create an ,educated public' very different in character from the electorates of contemporary democratic regimes. It concludes with some remarks on the role of education in combating prejudice against certain kinds of human difference. [source] Constructing Compliance: Game Playing, Tax Law, and the Regulatory StateLAW & POLICY, Issue 1 2007SOL PICCIOTTO This article proposes a rethinking of approaches to compliance, extending perspectives that view regulation as an interactive or reflexive process mediated by sociolinguistic practices. These suggest that the meaning of rules is not fixed ex ante, but may emerge and change through such interactions, which therefore actually help to construct what it means to comply. The analysis supports proposals to base tax law on purposive general principles combined with detailed rules. However, it suggests that this should be the approach adopted for the tax code as a whole, instead of focusing mainly on the merits of a general anti-avoidance principle, as some of the recent debates have done. The article explores the question of interpretation of rules and the problem of avoidance and game playing. It reexamines the issue of the indeterminacy of rules and relocates it within the context of professional and regulatory practices, suggesting that it is these interactions that construct the meaning of rules and hence of compliance. The analysis is applied to income taxation, to sketch out how the international tax system has been constructed through the interaction of contending views of fairness in the allocation of tax jurisdiction, while in the process becoming refined into a formalist and technicist process of game playing. It argues that the central factor in this process has been the inherent contestability of the core concepts of international taxation, the rules on corporate residence and source of income. The article concludes by considering some of the current proposals for improving tax compliance, in particular by reducing complexity, improving clarity, and the use of broad principles. [source] Relevant behavioural and social science for medical undergraduates: a comparison of specialist and non-specialist educatorsMEDICAL EDUCATION, Issue 10 2006Sarah Peters Aim, To compare what medical educators who are specialists in the behavioural and social sciences and their non-specialist counterparts consider to be core concepts that medical graduates should understand. Background, Previously perceived as ,nice to know' rather than ,need to know', the General Medical Council (GMC) now places behavioural and social sciences on the same need-to-know basis as clinical and basic sciences. Attempts have been made to identify what components of these topics medical students need to know; however, it remains unknown if decisions over programme content differ depending on whether or not educationalists have specialist knowledge of the behavioural and social sciences. Methods, In a survey of medical educationalists within all UK medical schools, respondents were asked to indicate from a comprehensive list of psychological, sociological and anthropological concepts what they considered a minimally competent graduate should understand. Comparisons were made between the concepts identified by specialist behavioural and social science (BSS) educators and those without such training. Results, Despite different disciplinary backgrounds, non-specialist educators largely concurred with BSS specialist educators in the concepts they considered tomorrow's doctors should know about. However, among BSS specialists there remained disagreement on what BSS content was relevant for graduates. Differences reflect specialist knowledge and recognition of the role of theoretical underpinning of BSS and reveal gaps in non-specialists knowledge. Conclusions, Educationalists with formal training in the full range of behavioural and social sciences should be involved in the development of BSS curriculum content at both national and school levels. [source] Patriotism, nationalism and modernity: the patriotic societies in the Danish conglomerate state, 1769,1814NATIONS AND NATIONALISM, Issue 2 2007JULIANE ENGELHARDT ABSTRACT. This article investigates sixty-three patriotic societies established in the Danish conglomerate state during the Age of Enlightenment, since they can throw light on the pre-national collective identities. It explains how the patriotic societies had both an external function in regard to society and an internal function among their members. It analyses how the members comprehended patriotism and how they propagated ideas of solidarity and good citizenship to a wider audience. The patriotism of the eighteenth century is also compared with the nationalism of the nineteenth century, and the way they reflect two different understandings of core concepts such as state, language and folk culture is explained. However, both ideologies correlate to modernity, since they reflect the same dialectic tension in the relationship between the individual, the social community and the modern state. [source] Patterns of parental authority and adolescent autonomyNEW DIRECTIONS FOR CHILD & ADOLESCENT DEVELOPMENT, Issue 108 2005Diana Baumrind In proposing connections among the paradigms represented by domain theory, parental control theory, and Baumrind's configural approach to parental authority, the worldview of each paradigm must be respected and ambiguities in core concepts must be resolved. [source] Rebuilding governance in failed states and post-conflict societies: core concepts and cross-cutting themesPUBLIC ADMINISTRATION & DEVELOPMENT, Issue 1 2005Derick W. Brinkerhoff This overview article looks at the emergence of failed and post-conflict states on the international relations and assistance agenda, and at the importance of governance in establishing peace, pursuing state reconstruction and preventing conflict. It introduces the topic of the special issue, how effective governance can be re-established following societal conflict or war. After a brief review of the terminology of failed states, post-conflict and governance, the article discusses governance reconstruction in terms of three dimensions: reconstituting legitimacy, re-establishing security and rebuilding effectiveness. The article summarises key points made by the contributors to the special issue, who look at donor governance reconstruction agendas, security-sector governance and subnational governance. Several common themes emerge and are elaborated upon: similarities between development and post-conflict assistance; linkages among governance's legitimacy, effectiveness and security dimensions; rebuilding versus creating governance systems; local versus national governance reconstruction; formal versus informal governance. The article concludes with a call for further work to elaborate frameworks that can incorporate the particulars of individual countries in addressing legitimacy, security and effectiveness.

The adoption of evidence-based practice is an important feature to ensure the profession's continued success. There are also other issues evident in Australian occupational therapy today that need to be considered to ensure the profession's continued growth. These are: the terminology that is and could be used in occupational therapy; the possibility of ,collateral damage' to occupational therapy concepts and processes if deterministic elements of evidence-based practice predominate; and the importance of making explicit our national position on occupational therapy core concepts and processes. Regarding the latter, the author proposes that this position is best described as ,finding unity in diversity'. This position reflects the national heritage, character and social/health priorities facing Australian occupational therapy. The implications of these issues are explored. [source] Quality of service in UMTS wireless networksBELL LABS TECHNICAL JOURNAL, Issue 2 2002Suresh Kumar This paper presents the realization of quality of service (QoS) in the Universal Mobile Telecommunications System (UMTS) network. The paper introduces an overview of the UMTS network structure that is an evolution of the Global System for Mobile Communications/General Packet Radio Service (GSM/GPRS) along with the motivation for providing QoS, as well as the QoS model in UMTS. Additionally, relevant considerations in delivering successful end-to-end QoS across a UMTS network are discussed. We also discuss trends toward QoS along with core concepts of QoS. The paper concludes with an outline of ongoing exploration of potential areas for future work. © 2002 Lucent Technologies Inc. [source] | |||||||||||||
