Child and Youth Coaching in families experiencing complex and multiple problems: A longitudinal evaluation study

Studies investigating services for families experiencing complex and multiple problems have emphasized the need for more child-centred support. The aim of this longitudinal study was to investigate whether providing child-centred services (Child and Youth Coaching) combined with family-focused services (Ten for the Future) is effective for children growing up in families experiencing complex and multiple problems. Children's psychosocial skills, emotional and behavioural problems, and the quality of their pedagogical environment were measured at baseline, 6 months and 12 months. Parent and coach reports of children indicated for Child and Youth Coaching (n = 57) and nonindicated children (n = 18) were analysed using repeated measures multilevel models. Both parents and coaches reported improved psychosocial skills of children, but changes were only significant for coach reports. In both reports, no significant decrease in emotional and behavioural problems was observed for both indicated and nonindicated children. Many children still experienced considerable problems at case closure. Furthermore, no significant improvement in quality of the pedagogical environment was observed in both groups. Given the limitations in this study, more research is needed to identify whether these findings can be replicated and attributed to the Child and Youth Coaching and Ten for the Future programmes.     

Constructing Copulas with Given Diagonal and Opposite Diagonal Sections

A method for constructing copulas with given diagonal and opposite diagonal sections is presented. It makes use of a recently developed method for constructing cross-copulas with given horizontal and vertical sections. Conditions guaranteeing the existence of a cross-copula with the given diagonal and opposite diagonal sections are derived. It is shown how the new method facilitates the construction of families of copulas that simultaneously model tail dependences of upper-upper, upper-lower, lower-lower and lower-upper type.     

High Production Volume Chemical Amine Oxides [C8–C20] Category Environmental Risk Assessment

An environmental assessment of amine oxides has been conducted under the OECD SIDS High Production Volume (HPV) Program via the Global International Council of Chemical Associations (ICCA) Amine Oxides Consortium. Amine oxides are primarily used in conjunction with surfactants in cleaning and personal care products. Given the lack of persistence or bioaccumulation, and the low likelihood of these chemicals partitioning to soil, the focus of the environmental assessment is on the aquatic environment. In the United States, the E-FAST model is used to estimate effluent concentrations in the United States from manufacturing facilities and from municipal facilities resulting from consumer product uses. Reasonable worst-case ratios of predicted environmental concentration (PEC) to predicted no effect concentration (PNEC) range from 0.04 to 0.003, demonstrating that these chemicals are a low risk to the environment.     

运动的激情与真正的成就——写在2008北京奥运会之前

来自运动(尤其是最高层次的运动)的许多经验都可以被运用于其他领域,而且在团队运动中最宜于研究成功的必要条件和过程.以团队运动为原型进行研究,得到了普遍性的结论,即内部竞争、民主自制、自我激励等都可以提高成就水平.其中,最具普遍性的是对自我满足行为的自我激励--对于所有创造性成就而言,自发的真正的动机是必不可少的条件,依赖于真实的个人动机(即本征动机)的本征成功也随之体现着积极的、创造性的个性.本征成功是源于本征动机而取得的成功,它是真正个人的成功,或者说,是真正或严格意义上的本征行为(个人真实的行动),其中表达的是深思熟虑的自我激励、自我投入、自愿完成的个人成就和行为.本征行为是创造性生命和自由社会的重要表现,自发从事的活动和真正的成就是人类自我理解的基本构成.不仅作为理性认知的存在,而且作为创造性存在、作为不断自我教化的社会和文化存在,人类都是真正实现着的存在.     

Forecasting the Educational Structure of Occupations: A Manpower Requirement Approach with Substitution

ABSTRACT: Manpower requirement forecasts are usually based on the assumption that discrepancies between supply and demand do not lead to adjustment processes at the labour market. We show, however, that even if the market mechanism functions completely, manpower requirement forecasts remain important information. On this basis, a manpower requirement approach is developed which incorporates the possibility of substitution processes at the labour market.     

DEMOCRATIC MECHANISMS

We introduce democratic mechanisms as a set of rules that must obey liberal democracy's fundamental principles of equal voting and agenda rights. We show that an appropriate combination of three rules may yield efficient provision of public projects: first, flexible and double majority rules, where the size of the majority depends on the proposal, and taxed and non‐taxed individuals need to support the proposal; second, flexible agenda costs, where the agenda‐setter has to pay a certain amount of money if his proposal does not generate enough supporting votes; third, a ban on subsidies. We highlight that universal equal treatment with regard to taxation is undesirable. Finally, we illustrate how simple constitutions involving fixed super majority rules yield socially desirable outcomes if the agenda‐setter is benevolent. (JEL: D62, D72, H40)     

An Explanation of the Occupational Structure of Sectors of Industry

Abstract. This study has been carried out by the Research Centre for Education and Labour Market (ROA) as part of a long-range research project commissioned by the Ministry of Education and Sciences. The objective of the project is to develop an education/labour-market information system to help secondary and university students choose the right type of school and/or occupation (ROA 1988). The study reported on here sets out to disclose the factors underlying the development of the occupational pattern. The shares of occupational classes in each economic sector are taken as points of departure. The explanatory variables are technological progress and cyclical and structural sectoral developments. For each occupational class, an estimation is made with the help of a linear model, the estimation method being that of Weighted Least Squares. To permit several variables to be included in the equation, the data have been pooled over sectors and time. In two fifths of all cases, a model with explanatory variables has been chosen; in the remaining instances a sector-dummy model was found to suffice.
