Heroin-assisted treatment in Switzerland: a case study in policy change

ADDICTION, Issue 1 2010
Ambros Uchtenhagen
ABSTRACT Background Switzerland introduced a pragmatic national drug policy when the former conservative abstinence-orientated politics proved unable to cope with an escalating number of users and related negative consequences for public health and public order. The high visibility of ,needle parks' and the size of the acquired immune deficiency disorder (AIDS) epidemic called for a new approach and for national leadership. Aims To describe the intentions, the process and the results of setting up the new treatment approach of prescribing heroin to treatment resistant heroin addicts, as an example of drug policy change. Materials and Methods A systematic collection of relevant documents is analysed and used as evidence for describing the process of policy change. Results Measures to reduce the negative consequences of continued use and to prevent the spread of AIDS were started mainly by private initiatives and soon taken up officially in the ,four-pillar' drug policy (including harm reduction, prevention, treatment and law enforcement). Medical prescription of heroin to chronic, treatment-resistant heroin addicts was one of the innovations, based on extensive scientific and political preparation. Detailed documentation and evaluation, ample communication of results, adaptations made on the basis of results and extensive public debate helped to consolidate the new policy and heroin-assisted treatment, in spite of its limitations as an observational cohort study. All necessary steps were taken to proceed from a scientific experiment to a routine procedure. Discussion Comparable policy changes have been observed in a few other countries, such as The Netherlands and Germany, based on the Swiss experience, with equally positive results of heroin-assisted treatment. These experiments were designed as randomised controlled trials, comparing intravenous heroin against oral methadone, thereby demonstrating the specific value of pharmaceutical diamorphine for maintenance treatment in opiate dependence. The positive impact of policy change and the positive outcomes of heroin-assisted treatment were acknowledged increasingly nationally and internationally, but made it difficult to continue the process of adapting policy to new challenges, due to the low visibility of present drug problems and to changing political priorities. Conclusion A major change in drug policy was effectively realised under typical conditions of a federalist country with a longstanding tradition of democratic consensus building. Facilitating factors were the size and visibility of the heroin problem, the rise of the Aids epidemic, and a pragmatic attitude of tolerating private initiatives opening the way to official policy change.

Exploring the Gaps between Meanings and Practices of Gender Equity in a Sport Organization

GENDER, WORK & ORGANISATION, Issue 3 2007
Larena Hoeber
This article analyses the explanations organizational members used to make sense of the meanings and practices of gender equity. Studying gender equity as an organizational value provided a way of understanding how gender inequity is perpetuated and embedded in the culture of an organization. This study was informed by post-structuralist feminist theory as it provided a lens for understanding and critiquing the local meanings and production of gendered knowledge, and encouraged discussion of transforming meanings and practices. This study was situated in a Canadian university athletic department in which gender equity was an espoused organizational value, but gender inequities were evident. Data were collected from in-depth interviews with administrators, coaches and athletes, observations of practices and competitions, and the analysis of relevant documents. These data were coded and categorized using Atlas.ti. Respondents' explanations for the gap between what was espoused and what was enacted centred on two dominant, but contradictory, themes: a denial of gender inequities and a rationalization of gender inequities. These themes suggested respondents often understood inequities as expected, natural, or normal. [source]


Clinical education facilitators: a literature review

JOURNAL OF CLINICAL NURSING, Issue 6 2005
Veronica Lambert BNS
Aims and objectives., The aim of this literature review, set within an Irish context, is to present a broad overview of former and existing clinical support personnel, explore the concept of facilitation and examine what is known about the role of the clinical education facilitator. Background., The importance of providing a supportive clinical environment to enhance clinical teaching and learning is strongly portrayed in the literature. While the past two decades have borne witness to various clinical support personnel, the literature identifies conflicting demands that these personnel face. No suggestions are advanced as to how to overcome these difficulties, which inevitably influence the quality and quantity of their clinical teaching role. An identifiable gap exists over who has prime responsibility for clinical teaching. It is timely that alternative possibilities for organizing clinical teaching are investigated. A new post emerging in practice settings is that of the clinical education facilitator who is meant to be the key linchpin in clinical areas for reducing the theory,practice gap. Method., Relevant literature for this review was sourced using the computerized databases CINAHL, Medline and Synergy. Manual searching of relevant nursing journals and sourcing of secondary references extended the search. Government reports and other relevant documents were obtained through pertinent websites. Results., Papers that explicitly examined the concept of facilitation and explored the posts of clinical education facilitators were included; six research papers were accessed and reviewed. In addition seven non-empirical papers were included. Conclusions., It is clear that considerable lack of role clarity resides over what constitutes clinical facilitation and the role of the clinical facilitator. Thus, it is paramount to strengthen this support role with Irish empirical evidence. Relevance to clinical practice., A major advantage in having a ward-based clinical education facilitator is the benefit of having access to someone who can concentrate solely on clinical education and support with attempts to narrow the theory,practice divide.

Data fusion according to the principle of polyrepresentation

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 4 2009

We report data fusion experiments carried out on the four best-performing retrieval models from TREC 5. Three were conceptually/algorithmically very different from one another; one was algorithmically similar to one of the former. The objective of the test was to observe the performance of the 11 logical data fusion combinations compared to the performance of the four individual models and their intermediate fusions when following the principle of polyrepresentation. This principle is based on cognitive IR perspective (Ingwersen & Järvelin, 2005) and implies that each retrieval model is regarded as a representation of a unique interpretation of information retrieval (IR). It predicts that only fusions of very different, but equally good, IR models may outperform each constituent as well as their intermediate fusions. Two kinds of experiments were carried out. One tested restricted fusions, which entails that only the inner disjoint overlap documents between fused models are ranked. The second set of experiments was based on traditional data fusion methods. The experiments involved the 30 TREC 5 topics that contain more than 44 relevant documents. In all tests, the Borda and CombSUM scoring methods were used. Performance was measured by precision and recall, with document cutoff values (DCVs) at 100 and 15 documents, respectively. Results show that restricted fusions made of two, three, or four cognitively/algorithmically very different retrieval models perform significantly better than do the individual models at DCV100. At DCV15, however, the results of polyrepresentative fusion were less predictable. The traditional fusion method based on polyrepresentation principles demonstrates a clear picture of performance at both DCV levels and verifies the polyrepresentation predictions for data fusion in IR. Data fusion improves retrieval performance over their constituent IR models only if the models all are quite conceptually/algorithmically dissimilar and equally and well performing, in that order of importance.

Corpus-based cross-language information retrieval in retrieval of highly relevant documents

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 3 2007
Tuomas Talvensaari
Information retrieval systems' ability to retrieve highly relevant documents has become more and more important in the age of extremely large collections, such as the World Wide Web (WWW). The authors' aim was to find out how corpus-based cross-language information retrieval (CLIR) manages in retrieving highly relevant documents. They created a Finnish,Swedish comparable corpus from two loosely related document collections and used it as a source of knowledge for query translation. Finnish test queries were translated into Swedish and run against a Swedish test collection. Graded relevance assessments were used in evaluating the results and three relevance criterion levels,liberal, regular, and stringent,were applied. The runs were also evaluated with generalized recall and precision, which weight the retrieved documents according to their relevance level. The performance of the Comparable Corpus Translation system (COCOT) was compared to that of a dictionary-based query translation program; the two translation methods were also combined. The results indicate that corpus-based CLIR performs particularly well with highly relevant documents. In average precision, COCOT even matched the monolingual baseline on the highest relevance level. The performance of the different query translation methods was further analyzed by finding out reasons for poor rankings of highly relevant documents. [source]


Relevance of Web documents: Ghosts consensus method

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 10 2002
Andrey L. Gorbunov
The dominant method currently used to improve the quality of Internet search systems is often called "digital democracy." Such an approach implies the utilization of the majority opinion of Internet users to determine the most relevant documents: for example, citation index usage for sorting of search results (google.com) or an enrichment of a query with terms that are asked frequently in relation with the query's theme. "Digital democracy" is an effective instrument in many cases, but it has an unavoidable shortcoming, which is a matter of principle: the average intellectual and cultural level of Internet users is very low,everyone knows what kind of information is dominant in Internet query statistics. Therefore, when one searches the Internet by means of "digital democracy" systems, one gets answers that reflect an underlying assumption that the user's mind potential is very low, and that his cultural interests are not demanding. Thus, it is more correct to use the term "digital ochlocracy" to refer to Internet search systems with "digital democracy." Based on the well-known mathematical mechanism of linear programming, we propose a method to solve the indicated problem. [source]


The benefits of skimming in data fusion

PROCEEDINGS OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE & TECHNOLOGY (ELECTRONIC), Issue 1 2007
Anselm Spoerri
Data fusion methods commonly use and compare all the documents returned by multiple retrieval systems to create a new result list. On the one hand, as documents further down in the result lists are considered, a document's probability of being relevant decreases significantly. On the other hand, retrieval systems tend to find similar relevant documents when searching the same database, but they do not find them in the same rank positions. Thus, data fusion methods need to consider all of the documents returned by the retrieval systems. Using TREC 3, 6, 7, 8, 12 and 13 data, this paper examines how "skimming", where the number of documents examined in the result lists is gradually increased, can help to identify relevant documents. It is shown that "gradual skimming" and what can be learned as the list depth is increased can help to improve the retrieval effectiveness of data fusion methods. [source]


Environmental strategies and green product development: an overview on sustainability-driven companies

BUSINESS STRATEGY AND THE ENVIRONMENT, Issue 2 2009
Vito Albino
Abstract To respond effectively and efficiently to the environmental sustainability challenge, an important role can be played by companies, through appropriate strategies and operations, such as green processes and product development. In this paper, we investigate whether the development of green products is supported by the environmental strategic approaches adopted by sustainability-driven companies, and whether there are economic sector or geographical area specificities. To this purpose, first we develop a taxonomy of environmental strategies and we define measurable proxies for both the environmental strategic approaches identified and the green product development. Then, we study a sample represented by the companies included in the Dow Jones Sustainability World Index (DJSWI). The methodology used is based on the content analysis of companies' websites and relevant documents, such as environmental and sustainability reports. The main result is that the levels of adoption of different environmental strategic approaches are higher for green product developers than for green product non-developers. Moreover, the most implemented strategic approaches for green product developers vary depending on the economic sector, while a more homogeneous behaviour is found from the geographical perspective.
