Objectives

There is much evidence showing that childhood adversities have considerable effects on the mental and physical health of adults. It could be assumed therefore, that the disease burden of childhood adversities is high. It has not yet been examined, however, whether this is true.

Method

We used data of a large representative sample (N = 7,076) of the general population in the Netherlands. We calculated the disability weight (DW) for each respondent. The DW is a weight factor that reflects the severity of a disease or condition on a scale from 0 (perfect health) to 1 (equivalent to death). We used an algorithm based on the SF-6D to estimate DW. Because the DW indicates the proportion of a healthy life year that is reduced by the specific health state of the individual, it also possible to calculate the total number of years lost due to disability (YLD) in the population. We calculated the years lived with disability (YLD) for 9 different childhood adversities (in the areas of parental psychopathology; abuse and neglect; major life events), as well as for major categories of mental disorders and general medical disorders.

Results

All 9 adversities resulted in a significantly increased DW, except death of a parent before the age of 16. Adversities in the category of abuse and neglect are associated with the highest DWs (0.057), followed by parental psychopathology (0.031) and life events during childhood (0.012). All adversities (46.4% of the population reports one or more adversity) are associated with 20.7 YLD/1,000, which is more than all mental disorders together (12.9 YLD/1,000). The category of abuse/neglect has the highest YLD/1,000 (15.8), which is also higher than all mental disorders together. Adjustment for the presence of mental and general medical disorders resulted in comparable outcomes.

Conclusions

Childhood adversities are more important from a public health point of view than all common mental disorders together, and should be a priority for public health interventions.  相似文献   

The influence of competences and support on school performance feedback use     

Jan Vanhoof  Jean Pierre Verhaeghe  Martin Valcke  Peter Van Petegem 《Educational studies》2011,37(2):141-154

Information‐rich environments are created to promote data use in schools for the purpose of self‐evaluation and quality assurance. However, providing feedback does not guarantee that schools will actually put it to use. One of the main stumbling blocks relates to the interpretation and diagnosis of the information. This study examines the relationship between data literacy competences, support given in interpreting the information, actual use of the feedback and potential school improvement effect. A randomised field experiment with 188 school principals from primary education was set up and a post‐test was used to investigate the effects of a support initiative. The results revealed that a minority of schools invested significantly in the interpretation and diagnosis of the school performance feedback (SPF), despite the fact that most of the respondents showed an interest in the SPF report. In addition, data competence support and the subsequent use of feedback were found to be limited.  相似文献   

Entrepreneurial effectiveness of European universities: An empirical assessment of antecedents and trade-offs     

Bart Van Looy  Paolo LandoniJulie Callaert  Bruno van PottelsbergheEleftherios Sapsalis  Koenraad Debackere 《Research Policy》2011,40(4):553-564

The phenomenon of entrepreneurial universities has received considerable attention over the last decades. An entrepreneurial orientation by academia might put regions and nations in an advantageous position in emerging knowledge-intensive fields of economic activity. At the same time, such entrepreneurial orientation requires reconciliation with the scientific missions of academia. Large-scale empirical research on antecedents of the entrepreneurial effectiveness of universities is scarce. This contribution examines the extent to which scientific productivity affect entrepreneurial effectiveness, taking into account the size of universities and the presence of disciplines, as well as the R&D intensity of the regional business environment (BERD). In addition, we assess the occurrence of trade-offs between different transfer mechanisms (contract research, patenting and spin off activity). The data used pertain to 105 European universities. Our findings reveal that scientific productivity is positively associated with entrepreneurial effectiveness. Trade-offs between transfer mechanisms do not reveal themselves; on the contrary, contract research and spin off activities tend to facilitate each other. Limitations and implications for future research are discussed.  相似文献   

Bringing together acculturation theory and intergroup contact theory: Predictors of Flemings’ expectations of Turks’ acculturation behavior     

Kaat Van Acker  Norbert Vanbeselaere 《Int J Intercult Relat》2011,35(3):334-345

The present paper explores Flemish majority members’ expectations concerning the acculturation of Turkish minorities. We studied two kinds of antecedents: majority members’ perceptions of Turkish minorities’ acculturation behavior and their experiences of intergroup contact. The possible mediating role of outgroup affect was also investigated. 247 Flemish high school students completed a survey. Data were analyzed using path analyses. Results show that positive contact experiences and perceiving that Turkish immigrants make efforts to engage in contact with the host group and/or to adopt the host culture are associated with less negative affective reactions towards Turkish migrants. Perceiving that Turkish immigrants maintain their heritage culture is associated with more negative affective reactions. Our results further revealed that increased negative affective reactions are associated with less support for culture maintenance and for contact with the host group but with a higher demand for host culture adoption. The present results also show that expectations of contact engagement and expectations of host culture adoption cannot be considered as equivalent. This implies that results from studies using Berry's conceptualization of acculturation expectations (Berry, 2001) and results from studies using Bourhis’ conceptualization of acculturation expectations (Bourhis, Moïse, Perreault, & Senécal, 1997) are not directly comparable. Our data also clearly disconfirm the orthogonal structure of the fourfold acculturation model for majority members’ acculturation expectations, suggesting that relying on the specific dimensions defining acculturation expectations may constitute a more valid approach to understand ongoing acculturation processes.  相似文献

Finite element modelling and experimental study of oblique soccer ball bounce     

Rezaei A  Verhelst R  Van Paepegem W  Degrieck J 《Journal of sports sciences》2011,29(11):1201-1213

In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us to conduct an accurate study on the effect of different parameters on a bouncing ball. This finite element model includes a surface-based fluid cavity to model the mechanical response between the ball carcass and the internal air of the ball. An experimental set-up was devised to study the bounce of the ball in game-relevant impact conditions. Ball speed, angle, and spin were measured before and after the bounce, as well as ball deformation and the forces during the impact. The finite element model has been validated with three different sets of data, and the results demonstrate that the finite element model reported here is a valuable tool for the study of ball bounce. After validation of the model, the effect of the friction coefficient on soccer ball bounce was studied numerically. Simulation results show that increasing the friction coefficient may result in reversal of the horizontal impact force.  相似文献
