Abstract This article presents original mixed method research to describe the use of rare illicit psychoactive substances, with special emphasis on crack cocaine in France. We first introduce a unique monitoring system committed to the observation of hard-to-reach populations. Qualitative findings rely, among others, on perennial ethnographic studies and field professionals’ knowledge to provide guidance to estimate the number of crack cocaine users. We then rely on a set of multilevel capture-recapture estimators, a statistical procedure to indirectly estimate the size of elusive populations. Since prior field evidence suggests an increasing diversity in crack cocaine users’ profiles, we provide a measure of heterogeneity to assess which estimator better fits the data. The calculated estimates are then critically reviewed and debated in light of the previously gathered information. Our results uncover both individual and institutional heterogeneity and suggest that the spread of crack cocaine in France initiated earlier than originally thought. Our case study underlines the need for field-driven assessments to put quantitative results into perspective, a necessary step to tailor efficient health policy responses.

Kirkpatrick’S Model

In the era of digital learning, multimedia-based classroom has been commonly used in higher education including Malaysian higher education institutions. A case study has been performed to evaluate web-based learning using Level 1 to 3 of Kirkpatrick's model in a multi-disciplinary course at Multimedia University, Malaysia. In this study, mixed method research was employed in which triangulation was performed from multiple sources of data collection to give deeper understanding. Students perceived that learning with multimedia was enjoyable. They were also motivated in learning and engaged through the use of web module as multimedia was perceived to motivate them and make learning fun. Students showed significant improvements in their knowledge based on the pre-test and post-test results on learning evaluation. Students were perceived to transfer the learning from web-based learning into the learning outcome. The systematic evaluation can provide the feedback that educators and institution as a whole need to improve the learning environment and programme quality. This study contributes to the research field by adding another perspective in evaluations of web-based learning. It also provides empirical evidence on student perspectives, learning and behaviour in a private university. It demonstrated that the Kirkpatrick's model is useful as an evaluation tool to be used in higher education.

ABSTRACT Objective: To assess the health/functioning of the older adult who consumes psychoactive substances through the International Classification of Functioning, Disability and Health, considering the theory of complexity. Method: Qualitative case study, with 11 older adults, held between December 2015 and February 2016 in the state of Rio Grande do Sul, using interviews, documents and non-systematic observation. It was approved by the ethics committee. The analysis followed the propositions of the case study, using the complexity of Morin as theoretical basis. Results: We identified older adults who consider themselves healthy and show alterations - the alterations can be exacerbated by the use of psychoactive substances - of health/functioning expected according to the natural course of aging such as: systemic arterial hypertension; depressive symptoms; dizziness; tinnitus; harmed sleep/rest; and inadequate food and water consumption. Final consideration: The assessment of health/functioning of older adults who use psychoactive substances, guided by complex thinking, exceeds the accuracy limits to risk the understanding of the phenomena in its complexity.

Quantitative Results

While studies have investigated UN Framework Convention on Climate Change (UNFCCC) meetings as drivers of climate change reporting as well as the geopolitical role of Pacific Islands in these international forums, little research examines the intersection: how media coverage of Pacific Islands and climate change (PICC) may be influenced by, or may influence, UNFCCC meetings. We analyze two decades of reporting on PICC in American, British, and Australian newspapers—looking at both volume and content of coverage—and expand the quantitative results with semi-structured interviews with journalists and Pacific stakeholders. Issue attention on PICC increases and the content changes significantly in the periods around UNFCCC meetings, with shifts from language about vulnerability outside of UNFCCC periods to language about agency and solutions. We explore the implications of these differences in coverage for both agenda setting and the amplification of emotional appeals in UNFCCC contexts.

Purpose – The purpose of this paper is to examine the effect of the fraud triangle, Machiavellianism, academic misconduct and corporate social responsibility (CSR) proclivity of students. Design/methodology/approach – The present study surveyed 471 university students. The study was cross-sectional and employed structural equation modelling in statistical modelling. Findings – The study provides evidence that perceived opportunity to cheat in examinations is the single most important factor accounting for significant variations in rationalization and academic misconduct. Similarly, low Machiavellians significantly get inclined to CSR ideals. The fraud triangle alone accounts for 36 per cent of the variations in academic misconduct, hence the error variance is 64 per cent of academic misconduct itself. This error variance increases to 78 per cent when a combination of perceived opportunity, rationalization, Machiavellianism is considered. Moreover, both Machiavellianism and academic misconduct account for 17 per cent of variations in students’ proclivity to CSR ideals. Research limitations/implications – Results imply that creating a setting that significantly increases a student's anticipated negative affect from academic misconduct, or effectively impedes rationalization ex ante, might prevent some students from academic misconduct in the first place and then they will become good African corporate citizens. Nevertheless, although the unit of analysis was students, these were from a single university – something akin to a case study. The quantitative results should therefore be interpreted with this shortcoming in mind. Originality/value – This paper contributes to the search for predictors of academic misconduct in the African setting and as a corollary, for a theory explaining academic misconduct. Those students perceiving opportunity to cheat in examinations are also able to rationalize and hence engage in academic misconduct. This rationalization is enhanced or reduced through Machiavellianism.

Abstract Performance assessment is a fundamental tool to successfully monitor and manage logistics and transport systems. In the field of Short Sea Shipping (SSS), the performance of the various maritime initiatives should be analyzed to assess the best way to achieve efficiency and guide related policies. This study proposes a quantitative methodology which can serve as a decision-support tool in the preliminary assessment and comparison of alternative SSS networks. The research is executed via a Mediterranean case study that compares a hypothetical Mediterranean ro-ro SSS network developed in the framework of a past Euro-Mediterranean cooperation project with the network of existing ro-ro liner services operating in the area. Performance benchmarking of the two networks is performed using a set of quantitative Key Performance Indicators (KPIs) and applying a factor-cluster analysis to produce homogeneous clusters of services based on the relevant variables while accounting for sample heterogeneity. Quantitative results mostly confirm the overall better performance of the prospective network and demonstrate that using KPIs and factor-cluster analysis to investigate the performance of maritime networks can provide policymakers with a preliminary wealth of knowledge that can help in setting targeted policy for SSS-oriented initiatives.

ABSTRACT Introduction: Worldwide cocaine use in all its various forms is increasing; cocaine users exceeded 17 million in the world. In Brazil, this data is also alarming. A survey conducted in 2010 found that the country has more than 900,000 crack-cocaine users. Objective: To evaluate the effects of exercise on anthropometric variables and components of physical fitness in ex-crack cocaine users. Methods: Randomized controlled trial with 20 men, divided into exercise group (n=10) and control group (n=10), admitted to a detoxification center. We assessed the physical fitness components related to health (cardiorespiratory endurance, flexibility, muscular strength/endurance, and body composition) before and after the physical training program. Results: The exercise contributed to the maintenance of anthropometric variables, while the control group had an increased in total body fat and visceral fat. Regarding physical fitness, resistance training led to the increase of most variables studied, particularly strength and cardiorespiratory capacity. On the other hand, the VO2max and the strength of the sedentary subjects were reduced (P<0.05). Conclusion: The exercise showed beneficial effects on the components of physical fitness and maintenance of body composition.

<p><strong>Purpose:</strong> The purpose of this paper is to identify and determine reasons why construction companies reject some of the request for proposals (RFPS) suitable for them. <br /><strong>Methodology/Approach:</strong> The research has several parts. Within the first part the list of reasons which lead to rejection of RFPS and thus potential client are identified. Then the comparison of differences between groups of rejected RFPS with different configuration is made. The last part of research use Pareto analysis to determine most obvious and most costly reasons of rejection of RFPS. <br /><strong>Findings:</strong> The paper identifies 12 reasons, why construction companies decline to prepare proposal for their potential clients. It also doesn’t confirm that configuration of RFPS has significant impact on the rejection of RFPS. Moreover the results on the other hand showed that insufficient trust represent the main barrier which influences the rejection of RFPS in selected company.<br /><strong>Research Limitation/implication:</strong> The main limitation of the research is that it is based on single case study. Although, the quantitative results have to be generalised very carefully, on the other hand paper provide list of the possible reasons why construction companies decline to compete for an offer. <br /><strong>Originality/Value of paper:</strong> The paper provides unique perspective because apart from traditional attitude, where only the submitted RFPS are evaluated, this paper analyses rejected RFPS and tries to identify and determine reasons why construction companies decide not to prepare proposal and thus reduce the possibility to acquire new contract.</p>

Hard To Reach Populations

Scholars have identified a range of factors that influence the ability of researchers to access hard-toreach groups and the willingness of their members to participate in research. In this paper, we draw on insights from both ethnographic methods and participatory action research to demonstrate the importance of building trust in our relationships with hard-to-reach participants in research based on interviews. Such trust-building, we show, is greatly facilitated by pre-recruitment immersion that aids not only the recruitment of individual participants but also improves the quality of the data collected. These methodological concerns emerged from an interview study focusing on Muslim women’s use of urban public recreational spaces in South-East Michigan. Although the first author of this paper, as a woman and a Muslim, is a formal insider in the study population, her experiences with recruitment demonstrate that the access granted by insider status is insufficient as grounds for a research relationship based on trust. This is so especially when the target population is as marginalized and embattled as the post 9/11 immigrant Muslim community. With more than two years of community immersion, however, she was able to foster enough trust to secure a large number of committed participants that spoke freely and thoughtfully about the issues at stake (78 in all).
