Mounting evidence suggests that early-life conditions have an enduring effect on an individual’s mortality risks as an adult. The contribution of improvements in early-life conditions to the overall decline in adult mortality, however, remains a debated issue. We provide an estimate of the contribution of improvements in early-life conditions to mortality decline after age 30 in Dutch cohorts born between 1812 and 1921. We used two proxies for early-life conditions: median height and early-childhood mortality. We estimate that improvements in early-life conditions contributed more than five years or about a third to the rise in women’s life expectancy at age 30. Improvements in early-life conditions contributed almost three years or more than a quarter to the rise in men’s life expectancy at age 30. Height appears to be the more important of the two proxies for early-life conditions. 相似文献
Drawing on discursive psychology this article examines the understandings teachers and principals in Danish Public Schools have regarding Somali diaspora parenting practices. Furthermore, the article investigates what these understandings mean in interaction with children in the classrooms and with parents in home–school communication. It is argued that in a society with increased focus on parental responsibility the teachers and principals draw on a deficit logic when dealing with Somali diaspora parents and children which consequently leads to teachers either transmitting their expertise by educating parents or compensating for perceived deficiencies in parental practices. Both these strategies result in significant marginalizing consequences where ‘difference’ is understood as ‘wrong’ or ‘inadequate’. 相似文献
This paper presents an analysis of levels of life expectancy and their patterns of change among six socio-economically differentiated sub-populations of England and Wales for the period 1851–1911. Differences in mortality levels among these sub-groups and their rates of change are analyzed with respect to three groups of explanatory variables, viz., environmental, stratification and demographic variables. Their relative importance for different periods is assessed and discussed. The findings show consistency with two previous studies, which have suggested that medical advances had little effect on the increase in life expectancy during the second half of the nineteenth century. The present paper supports the results of one study in that public health measures affected life expectancies earlier, while subsequently, the increase in standards of living was more important. 相似文献
The present article draws attention to ways in which the goodness of fit between social services and their clients, both in the present and the past, determines the extent to which services are successful–in the sense that clients experience them as helpful and as furthering their well-being, and that there is objective evidence of improvement in their situation.
To provide an initial conceptual framework for exploration in this area, a number of terms are introduced and defined. These include ‘inapt service”, ‘inaptly served families’, and ‘good enough services’.
It is contended that biases that promote inaptness, in the areas of policy, organization, practice, and research and evaluation, have contributed to the proliferation and perpetuation of inapt services. As a basis for further reflection and for efforts to transform ‘inapt’ service systems into ones that are ‘good enough’, twelve such biases are discussed.
Finally, premises and directions for action that promote such transformative efforts are suggested. 相似文献
Theories (and experiments) on decision making under risk typically ignore (and exclude) a social context. We explore whether
this omission is detrimental. To do so we experimentally investigate the simplest possible situation with both social comparison
and risk: participants choose between two lotteries while a referent faces a fixed payoff. Participants are more risk averse
when they can earn at most as much as their referent (loss situation) than when they are ensured they will earn at least as
much as their referent (gain situation). Prospect theory with a social reference point would predict the exact opposite behavior.
These results show that straightforward extensions of existing theories to allow for social comparison do not provide accurate
predictions. 相似文献
Studies in the field of body image have primarily addressed its negative aspects, such as body dissatisfaction. The present study focused instead on women who are satisfied with their bodies and on how body satisfaction relates to sexual health. A sample of 319 Dutch female university students completed an online survey that included items about body image evaluation, body image investment, overweight preoccupation, body image affect during sexual activity, sexual frequency, sexual functioning, and sexual self-esteem. We found that the level of body dissatisfaction was minimal in our sample. The majority reported neutral or mildly positive body evaluations, and in 30% of the sample these evaluations were clearly positive. Comparisons between women who reported positive versus neutral body evaluations showed that the body-satisfied women had lower body mass indexes (BMIs) and reported less body image investment, less overweight preoccupation, and less body self-consciousness during sexual activity. With regard to sexual health, they reported higher sexual self-esteem and better sexual functioning. Furthermore, we found that body image self-consciousness was negatively associated with sexual functioning, sexual self-esteem, and frequency of sexual activity with a partner. Body satisfaction did not account for a portion of the relationship of body self-consciousness during sexual activity with sexual health. 相似文献
This study is an analysis of mortality levels and their patterns of change among different socio-economic groups in two eighteenth-century Dutch villages. In these two villages – Gilze and Rijen – there were substantial mortality differentials between farmers and agricultural labourers. Mortality differentials of this magnitude have not been found in other European villages, although they are not unheard of in cities. The differentials are probably unrelated to malnutrition, or a polluted water supply among the lower class. Relative overcrowding and poor hygiene are more probable causes. During the second half of the eighteenth century mortality levels were lower, especially among the lower class. These changes, however, did not result from a higher standard of living. They were probably related to a diminution in the amount of military activity on land in Europe after the War of the Austrian Succession. 相似文献
The authors of this article have developed six probabilistic causal models for critical risks in tunnel works. The details of the models' development and evaluation were reported in two earlier publications of this journal. Accordingly, as a remaining step, this article is focused on the investigation into the use of these models in a real case study project. The use of the models is challenging given the need to provide information on risks that usually are both project and context dependent. The latter is of particular concern in underground construction projects. Tunnel risks are the consequences of interactions between site‐ and project‐ specific factors. Large variations and uncertainties in ground conditions as well as project singularities give rise to particular risk factors with very specific impacts. These circumstances mean that existing risk information, gathered from previous projects, is extremely difficult to use in other projects. This article considers these issues and addresses the extent to which prior risk‐related knowledge, in the form of causal models, as the models developed for the investigation, can be used to provide useful risk information for the case study project. The identification and characterization of the causes and conditions that lead to failures and their interactions as well as their associated probabilistic information is assumed to be risk‐related knowledge in this article. It is shown that, irrespective of existing constraints on using information and knowledge from past experiences, construction risk‐related knowledge can be transferred and used from project to project in the form of comprehensive models based on probabilistic‐causal relationships. The article also shows that the developed models provide guidance as to the use of specific remedial measures by means of the identification of critical risk factors, and therefore they support risk management decisions. Similarly, a number of limitations of the models are discussed. 相似文献
