Contemporary issues and future directions for research into pathological gambling

ADDICTION, Issue 8 2000
Article first published online: 2 SEP 200
The recent healthy increase in research into all aspects of gambling is noted. The dominant theme accounting for most of this research is the mental disorder model of pathological gambling and measures that have been derived from this conceptualization. It is suggested that an alternative approach focusing on the construct of choice or subjective control over gambling may be a research direction that will ensure that progress is maintained. In this paper a context for the discussion is provided by first identifying briefly fundamental conceptual and methodological issues associated with the mental disorder model. In particular it is argued that the heterogeneity of the diagnosis of pathological gambling makes the research task of assessing truly independent variables extremely difficult. Subsequently an illustrative schema is presented that demonstrates both the potential advantages and some of the complexities associated with the dependent variable of self-control over gambling behaviour. The main advantages are argued to be (a) the focus of research is narrowed to one potential cause of harmful impacts rather than the great diversity of impacts themselves, (b) prospective studies of regular gamblers in real gambling venues may be a key source of insight into the development of pathological gambling and (c) it promotes the development of theoretical links with the mainstream of the discipline of psychology. Despite the conceptual difficulties that may be associated with the variable of self-control, it is suggested that these may be overcome because contemporary research into the addictive behaviours has demonstrated considerable success in the definition and measurement of control and related themes such as craving, restraint and temptation.

Gingival involvement of oral lichen planus in a series of 700 patients

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2005
Michele D. Mignogna
Abstract Background: Oral lichen planus (OLP) is one of the most common oral mucosa disorders. OLP gingival involvement is very frequently observed, and it is characterized by wide variations in clinical appearance and symptoms, leading, in many cases, to misdiagnosis or undiagnosis. This can be potentially harmful since OLP patients require appropriate management in oral and periodontal care, together with an adequate systemic evaluation. Objective: In this paper, we have analysed the prevalence and clinical aspects of gingival lesions in our series of 700 patients affected by OLP. Furthermore, we have discussed the possible periodontal implications on the basis of the available literature. Patients and Methods: Data from 700 patients affected by OLP, clinically and histologically assessed, have been studied; the location and morphology of lesions, the symptoms and the progression of the disease have been considered, with particular attention given to gingival involvement. Results: Gingival lesions have been diagnosed in 48% of cases, usually associated with diffuse oral involvement. Only 7.4% of patients had OLP lesions confined to the gingiva. The morphology of lesions included all the forms originally described for OLP (reticular, papular, plaque, atrophic, erosive and bullous). The symptoms, if present, varied from mild discomfort to severe oral pain, with the general trend increasing from the keratotic to the erosive forms. The gingiva was involved in four out of 21 of our oral cancer cases, which developed from pre-existing OLP lesions. Conclusion: OLP is a very proteiform disorder; considering the high frequency of gingival involvement and its influence on oral health, it is our opinion that periodontologists should be involved in OLP management and should become familiar with its clinical aspects and related themes.

Green Energy or Organic Food?: A Life-Cycle Assessment Comparing Two Uses of Set-Aside Land

JOURNAL OF INDUSTRIAL ECOLOGY, Issue 3 2001
Richard van den Broek
Summary Bioenergy has a large worldwide potential in future climate change abatement, although its application may become limited by demands for land for other functions. The aim of this study was to make an environmental assessment of the use of energy crops in the Netherlands in a context that incorporates scarcity of land. A base case system was defined, consisting of conventional winter wheat production, set-aside land (1 hectare, together), and the production of coal-based electricity. Using life-cycle assessment, we compared this system with (1) a green energy system in which willow is cultivated on the set-aside land to replace the coal-based electricity and (2) an organic agriculture system in which the full hectare produces wheat under the Dutch EKO organic agriculture standard. In this way, the functional unit and the amount of land used is the same in each system. The final system comparison was based on normalized scores per environmental theme. The green energy system scored the best with respect to acidification, climate change, and energy carrier depletion. The organic food system scored best on terrestrial eco-toxicity and slightly better on the mutually related themes of seawater and seawater sediment eco-toxicity. The base case system performed slightly better with regard to eutrophication. Preferences, from an environmental point of view, for one of the systems should be determined by environmental policy priorities and the severity of local environmental problems. The case studied here shows that when climate change, energy carrier depletion, and acidification are the main drivers behind environmental policy, one should focus not on the extensification of agriculture, but rather dedicate more land to energy crops. Extensification of agriculture would be the preferred system when toxicity from pesticides is considered the main problem. [source]


Legal Mobilization and the Politics of Reform: Lessons From School Finance Litigation in Kentucky, 1984-1995

LAW & SOCIAL INQUIRY, Issue 3 2001
Michael Paris
This article is about legal mobilization by claimant groups seeking left-liberal reform in the United States. Drawing on a growing body of work in political science and legal studies, it takes an interpretive, legal-mobilization approach to one litigation-based reform effort: school finance litigation and education reform in Kentucky. In turn, this case study provides leverage for theorizing about legal mobilization and the role of law and courts in social reform. The article argues that current theoretical approaches either overlook or neglect the implications of important dimensions of legal mobilization by would-be reformers. Specifically, it highlights and explicates the meaning of two related themes: (1) legal translation, taken up here as legal framing and legal construction, and (2) the degree of coherence or fit between the legal and political components of reform projects that include both legal mobilization and extrajudicial strategies and tactics. This article suggests that the "degree of coherence" may have an important but underappreciated relationship to the overall success or failure of such reform projects. [source]


Discretion unbound: Reconciling the Charter and soft law

CANADIAN PUBLIC ADMINISTRATION/ADMINISTRATION PUBLIQUE DU CANADA, Issue 4 2002
Lorne Sossin
This study explores the relationship between discretion and the Charter and argues for a broader, more contextual approach to remedying the source of unconstitutional discretion. Guidance as to how to exercise broad discretionary authority comes in the form of "soft law," which encompasses a variety of non-legislative instruments such as policy guidelines and training materials, and which, more informally, extends to administrative culture. Administrative discretion involves choices and judgements usually shaped by a range of legal, bureaucratic, social and personal factors. Under present jurisprudence, the less precise a statutory discretion and the greater the reliance on non-legislative guidelines, the more difficult that discretion will be to subject to constitutional scrutiny. This article challenges this logic and concludes that respect for governmental accountability and the rule of law require bringing soft law out of the constitutional shadows. The first part of the analysis examines the regulation of discretion generally and soft law specifically outside the Charter. The second part analyses the leading case law on the regulation of discretion under the Charter. The third section explores the intersection of discretion, soft law and the Charter. Finally, the fourth section considers the problem of remedying unconstitutional exercises of discretionary authority. Alternative principles are suggested for the development and application of soft law, which envisions a central role for the Charter in rendering the discretionary decision-making process more accountable and just.
