L'indicateur «Embauche des travailleurs» de la Banque mondiale: bilan des travaux et critiques

Cette note fait le point sur le débat suscité par le projet Doing Business de la Banque mondiale, et notamment par son indicateur «Embauche des travailleurs», censé mesurer la difficulté d'embaucher, la rigidité de la durée du travail et la difficulté de licencier. Les auteurs présentent les résultats des études qui l'ont utilisé, l'ont inspiré ou ont été influencées par cet indicateur. Ils se penchent ensuite sur les critiques de cet instrument qui pose des problèmes conceptuels et empiriques. Ils concluent par la formulation de suggestions pour les recherches à venir.     

Adolescents' and Their Mothers' Perceptions of Parental Management of Peer Relationships

The purpose of the present investigation was to examine the relation of level and discrepancy in mothers' and adolescents' reports of parental management of peer relationships and parent–child conflict about peer relationships to mothers' and adolescent's reports of adolescents' drug use, delinquent behavior, and grade‐point‐average (GPA). An ethnically diverse sample of 121 seventh and eighth graders and their mothers completed questionnaires assessing the degree to which mothers managed peer relationships, parent–child conflict about peer relationships, and adolescents' drug use, delinquent behavior, and GPA. Differences in mothers' versus adolescents' reports were found for parental management of peers and conflict about peer relationships. Results suggest that both level and discrepancies between mothers' and adolescents' reports of parenting are important in predicting the outcome variables. Furthermore, the direction of the discrepancy was important in determining its relation to the outcome variables.     

Evaluation of a major financial incentive for in-home energy conservation

A mail questionnaire methodology was utilized to provide baseline data on consumers' reactions to the Canadian Oil Substitution Program (COSP). COSP is a major financial incentive, operated by the Canadian government, designed to stimulate conversions of oil-fired home hearing systems to alternative energy sources.The results provide a snapshot of consumer reactions one year after the COSP incentive was first introduced. Specific results include the motives for and barriers to off-oil conversion; the importance of COSP, relative to other conversion motives; and the size and characteristics of the oil-user group who are resistant to converting off-oil heating. Implications for program management and directions for future research are discussed.     

‘All those in favour’: computerised trade union membership lists as sampling frames for postal surveys

The computerisation of membership lists offers considerable scope for postal surveys of trade unionists. However, faith in the new technology can give rise to the illusion of increased accuracy. Yet, the computerised data bases, while undoubtedly quicker and easier to use, may be no more accurate than their manual predecessors and samples drawn from them can result in misleading response rates. Therefore, with reference to a specific case study of a major trade union, we argue that researchers should seek to establish empirically the probable error in their lists with a view to constructing realistic ‘benchmarks’. Then, these substantial new resources can provide a solid basis for worthwhile research.     

Gambling and problem gambling among clients,and staff attitudes,in an alcohol and drug problems treatment service in the English Midlands

A self-completion questionnaire containing items about recent gambling and problem gambling used in the British Gambling Prevalence Survey (BGPS) was completed by 274 clients of alcohol and drug problems services in the English West Midlands. Compared to BGPS data, matched to the client sample for age and sex, clients were significantly more likely in the previous 12 months to have engaged in forms of gambling carrying a high risk of problems, to have engaged in four or more separate forms of gambling, and to have scores on a brief form of the South Oaks Gambling Screen (SOGS) indicating problem gambling. A self-completion scale on attitudes towards working with problem gamblers, with good psychometric properties according to present data, was completed by 91 members of staff of the same services. With the exception of a sub-scale measuring perceived adequacy of knowledge and skills for working with problem gamblers, staff expressed moderately positive attitudes. It is concluded that British substance misuse services are appropriate locations for the development of services for problem gambling.     

Eating Disorder Symptoms Among College Students: Prevalence,Persistence, Correlates,and Treatment-Seeking

Abstract

Objective: To examine the prevalence, correlates, persistence, and treatment-seeking related to symptoms of eating disorders (EDs) in a random sample of college students. Participants: A random sample of students at a large university were recruited for an Internet survey in Fall 2005 and a follow-up survey in Fall 2007. Methods: ED symptoms were measured using the SCOFF screen and adjusted for nonresponse using administrative data and a nonresponse survey. Results: 2,822 (56%) students completed the baseline survey. Among undergraduates the prevalence of positive screens was 13.5% for women and 3.6% for men. Among students with positive screens, 20% had received past-year mental health treatment. In the follow-up sample (N = 753), ED symptoms at baseline significantly predicted symptoms 2 years later. Conclusions: Symptoms of EDs were prevalent and persistent among college students in this study. These findings suggest that brief screens can identify a large number of students with untreated EDs.     

Chemistry of growth medium and leachate from green roof systems in south-central Texas

Installation of intensive and extensive green roofs is becoming popular for reducing runoff from impervious surfaces in many cities around the world. Most studies on runoff quality from green roofs have been conducted in cooler northern climates. We examined the losses and gains of nutrients, cations and selected anions in planted and unplanted growth medium and compared these to initial growth medium (IGM) typically used for green roof modules in south-central Texas. Water extracts of growth medium and leachate from three replicates of unplanted growth medium and three planted species (Sedum kamtschaticum, Delosperma cooperi and Talinum calycinum) were examined. During the first 6 months after establishment we observed high losses of nitrate (25 to 44 mg kg⁻¹), dissolved organic carbon (DOC: 155 to 190 mg kg⁻¹) and nitrogen (DON: 9.0 to 11.2 mg kg⁻¹) and orthophosphate-P (1 to 2 mg kg⁻¹). Average leachate concentrations based on four rain events 6 months after establishment ranged from 0.3 to 6.6 mg L⁻¹ in planted modules and 6.3 mg L⁻¹ in unplanted modules for nitrate-N, 38 to 42 mg L⁻¹ in planted modules and 32 mg L⁻¹ in unplanted modules for DOC, 2.1 to 3.1 mg L⁻¹ in planted modules and 2.1 mg L⁻¹ in unplanted modules for DON and 0.27 to 0.37 mg L⁻¹ in planted modules and 0.40 mg L⁻¹ in unplanted modules for orthophosphate-P. We suggest that after the establishment of green roofs, leachate losses may contribute some runoff concentrations of nitrogen, carbon and phosphorous in urban areas.     

Connecting with Parents: Mothers' Depressive Symptoms and Responsive Behaviors in the Regulation of Social Contact by One- and Young Two-year-olds

When children act to involve mothers in positive interaction, they influence the amount, timing, and content of parent–child exchanges. By assessing children's smiling and positive initiation, we examined child behaviors that function to create positive interaction. In a non-clinical North American sample of 103 mothers and their 14- to 27-month-olds, we observed that children attempted to connect positively with mothers (1) more with age, (2) more frequently and quickly immediately after mothers were responsive, (3) more with mothers who were generally supportive, and (4) more with mothers low in depressive symptoms. When mothers were high in depressive symptoms, age-related increases in smiling and positive initiation were absent. Findings demonstrate the importance of maternal depression and responsiveness to child behaviors that involve mothers in ongoing activity. They suggest that both immediate cues and children's stored knowledge related to how mothers will respond may regulate children's positive connecting behaviors.
