Adolescents' beliefs about marijuana use: a comparison of regular users, past users and never/occasional users

A questionnaire investigating adolescents' opinions and experiences regarding marijuana use was administered to 163 adolescents and young adults (96 boys and 67 girls) aged 13 to 20 (mean age = 16.8, s.d. = 1.5). Items referred to marijuana and other substances' dangerousness, representations regarding the positive and negative consequences of marijuana use. Responses were compared according to marijuana use status (classified into never/occasional use, current regular use and past regular use). Results show that adolescents' opinions differ according to their experience with marijuana use. Current regular users evaluate marijuana as less dangerous, but alcohol and heroin as more dangerous in comparison with never/occasional and past users. Current and past users are more likely to define marijuana as a medical drug and a plant used in agriculture, and less likely to define it as an illegal drug. Current and past users evaluate marijuana use as a way to cope with stress, to relax to a greater extent than do never/occasional users do. The latter attribute more negative consequences to marijuana use such as diminished driving ability and school performance and a pathway to hard drugs.     

An ALARA Approach to the Radiological Control of Foodstuffs Following an Accidental Release

This article presents a methodology based on two complementary approaches, thus allowing a selection of maximal concentration in foodstuffs for determining appropriate countermeasures. The first approach is based on a minimal and maximal per capita intervention level and takes into account the annual intake of each product. The second one is based on a cost-benefit analysis, comparing the advantages of a countermeasure concerning those products presenting a contamination higher than a given maximal concentration (in terms of reduction of cost of the detriment associated with the risk), with its drawbacks (in terms of cost of the products) in order to select the "ALARA" maximal concentration. This second approach is used as a complement to the first one. The results obtained through these two approaches are given for four products (milk, meat, fresh vegetables, and corn) and two nuclides (Cs-137 and I-131). These are presented for various scenarios: one or various products contaminated by one or various radionuclides. It is concluded that these two approaches are complementary, the first one being related to individual risk and the second to collective risk. Therefore, these approaches are both of interest in the context of the elaboration of modalities for the radiological control of foodstuffs following an accidental release and both methods may be useful for determining appropriate countermeasures.     

Parents' Attitudes and Knowledge Regarding Gambling Among Youths

This study evaluates attitudes and knowledge of parents regarding gambling behaviors among youths, aged 5 to 17 years. Telephone interviews were conducted among 279 randomly selected parents (32% fathers and 68% mothers) in the Quebec City region. Results indicate that parents overestimate the age of children's first wagers and underestimate the probability that their own child has already gambled. Most parents (86%) believe that the availability of gambling for youths should be reduced and that schools should include prevention programs concerning problem gambling. Results also show that parents fail to associate excessive gambling with poor grades or with alcohol and drug use. Finally, 84% of the parents reported that they would accept buying lottery tickets for their child. These results suggest that prevention programs for excessive gambling among children should include information for parents.     

Mortality in Belarus, Lithuania, and Russia: Divergence in Recent Trends and Possible Explanations

Before the collapse of the Soviet Union, Belarus, Lithuania, and Russia were quite comparable in terms of their socioeconomic development. Despite some differences in overall mortality levels, the three former Soviet republics were also very close to each other in terms of directions of mortality trends and age- and cause-specific mortality patterns. After 1991, all the three countries experienced substantial political and social transformations, and the challenges associated with the transition from a socialist to a market economy system. The sudden changes brought numerous problems, such as rapid growth in unemployment, falling standards of living, and growing social and income inequalities. These factors contributed to the significant deterioration of the health situation in all the countries, but the size and the nature of the mortality crisis was different in Belarus than it was in Lithuania and Russia. The marked similarities in socioeconomic and mortality trends in the countries up to 1991 contrast with their notable divergence during the subsequent years. The nature and success of market reforms seems to be the most plausible explanation for these differences. Russia and Lithuania have chosen more radical forms of economic and political transformations, which have led to massive privatization campaigns. The reforms were more sustainable and systematic in Lithuania than in Russia. By contrast, Belarus has chosen a gradual and slow transition path. Recent mortality trends in Belarus are explored in detail here, and are contrasted with those observed in Lithuania and Russia. Including a cause-of-death analysis sheds more light on the plausible determinants of the variations in mortality levels between the countries.

International Firm Strategies: Is Cultural Distance a Main Determinant?

According to prior literature, risk determines the international strategies firms adopt, together with cultural and geographical distance. However, the effect of distance, whether cultural or geographical, remains insufficiently tested and seemingly contradictory. To investigate the potential determinants of international firm strategies, this study draws a sample of 759 Japanese subsidiaries worldwide. Statistical analyses confirm the ambiguous effect of distance (cultural and geographical) on internationalization strategies, especially compared with the effect of risk.     

Engaged or Connected? A Perspective of the Motivational Pathway of the Job Demands-Resources Model in Volunteers Working for Nonprofit Organizations

There is a paucity of research on volunteers compared with paid workers. The aim of this study is to examine the mediating roles of work engagement and connectedness simultaneously in the motivational pathway of the Job Demands-Resources (JD-R) model. Survey data were collected from 471 volunteer participants and analysed using structural equation modelling methods. Contrary to expectation, the findings did not show that engagement mediates the relationship between job resources and volunteer satisfaction (1), between job resources and determination to continue (2), and between job resources and health (3). The findings, did however, show that connectedness mediates the relationship between job resources and volunteer satisfaction (4), between job resources and determination to continue (5), and between job resources and health (6). These findings add support to the motivational pathway of the JD-R theory to understand volunteer wellbeing and retention in health care organizations, but suggest that the theory may be expanded to include connectedness as a mediator.     

(Re)Conceptualising inclusive education in New Zealand: listening to the hidden voices

This article explores the experiences of 14 students with severe and complex behaviour, their caregivers, and teachers/principals as the students transition from a disestablished residential school back to mainstream schools, with support from the Intensive Wraparound Service (IWS). Interviews were the primary source of data collection. Data were collated into 14 cases, and analysed using a general inductive approach. Two broad themes are addressed in the article: education and relationships/communication. The research found that the IWS is not living up to its rhetoric. Suggestions made for improvement are based on approaches that participants found worked for them.     

From susceptibility to frailty in social networks: The case of obesity

The obesity pandemic is represented by a discrete-time Hopfield Boolean network embedded in continuous-time population dynamics. The influence of the social environment passes through a system of differential equations, whereby obesity spreads by imitation of the most influential neighbors, those who have the highest centrality indices in the network. This property is called “homophily.” Susceptibility and frailty are redefined using network properties. Projections of the spread of obesity are validated on data collected in a French high school.
