The transdisciplinary key worker model requires early childhood intervention professionals to make radical adjustment in their respective scopes of knowledge and practice. Focused on the author’s brief experience in a key worker role, the article highlights challenges and contradictions that arise when health and welfare professionals are expected not only to exchange knowledge, skills, and expertise, but also to perform each other’s work. Two contextual, reflective accounts of the reasons why social workers should be cautious in task transfers in transdisciplinary teams are given. The article renews support for social workers playing professionally appropriate roles in early childhood intervention teams in ways that can protect best service delivery to children with disability and their families. 相似文献

Despite numerous studies on motivation for generosity, much remains unknown. Given that the lion's share of giving and volunteering is directed toward religious institutions, we aimed to test the motivation for the generosity of Mormons. Previous research has indicated that Mormons (Latter‐day Saints) volunteer and donate at much higher levels than other groups. This study examined how self‐reported motivations to volunteer explain the annual number of hours volunteered and the likelihood of donating toward various causes. We used thirty qualitative interviews with Latter‐day Saints to create a comprehensive questionnaire measuring the time spent engaged in various volunteer activities and whether or not the respondents donated to various causes. The questionnaire also asked respondents to rank how important twenty‐five different motivations were to their service or volunteering. We used factor analysis of the results on the twenty‐five motivation items to identify underlying variables behind volunteer motivations, and we used the scores on the five resulting factors in multiple regression analyses to predict volunteer hours and logistic regression analyses to predict the likelihood of making donations. Different types of motivations predicted different types of volunteering and charitable giving. Theological motivations had the broadest impact and predicted religious volunteering, social volunteering to benefit church members, social volunteering through the church to benefit the community, religious donations, and donations toward social causes made through the church. After inserting control variables into our models, we found that none of the five types of motivations predicted secular volunteering or secular charitable giving. We conclude with managerial and conceptual implications of these and other results. 相似文献

The measurement of walkway slip resistance is required to assess the risk of slipping. Unlike other countries, the U.S. has not decided upon a single approach to the measurement of slip resistance. Several types of tribometers are available to measure slip resistance however, the measured value of the slip resistance of a given surface has been found to be tribometer specific. The introduction of ASTM International Standard F2508 Standard Practice for Validation and Calibration of Walkway Tribometers Using Reference Surfaces, has produced a method which allows validation of each type of tribometer and the values generated during testing. 相似文献

Children growing up in homes with many books get 3 years more schooling than children from bookless homes, independent of their parents’ education, occupation, and class. This is as great an advantage as having university educated rather than unschooled parents, and twice the advantage of having a professional rather than an unskilled father. It holds equally in rich nations and in poor; in the past and in the present; under Communism, capitalism, and Apartheid; and most strongly in China. Data are from representative national samples in 27 nations, with over 70,000 cases, analyzed using multi-level linear and probit models with multiple imputation of missing data. 相似文献

In this article, drawing on qualitative interviews and documentary analysis, we argue that the Jewish community in Britain has undergone a fundamental shift since 1990 from a 'strategy of security', a strategy of communal leadership based on emphasizing the secure British citizenship and belonging of the UK's Jews, to a 'strategy of insecurity', where the communal leadership instead stresses an excess of security among Anglo-Jewry. We demonstrate this based on two case studies: of the Jewish renewal movement in the 1990s and the 'new antisemitism' phenomenon of the 2000s. We conclude that this shift is tied to the shift from a monocultural Britain to an officially multicultural one, and that therefore there are lessons that can be taken from it for the study of British and other multiculturalisms. 相似文献

Orphans and schooling in africa: a longitudinal analysis 总被引:4,自引:0,他引:4
AIDS deaths could have a major impact on economic development by affecting the human capital accumulation of the next generation. We estimate the impact of parent death on primary school participation using an unusual five-year panel data set of over 20,000 Kenyan children. There is a substantial decrease in school participation following a parent death and a smaller drop before the death (presumably due to pre-death morbidity). Estimated impacts are smaller in specifications without individual fixed effects, suggesting that estimates based on cross-sectional data are biased toward zero. Effects are largest for children whose mothers died and, in a novel finding, for those with low baseline academic performance. 相似文献

This inquiry examines comparative trends in collaboration among scholars, both over several decades and for several scientific disciplines. Findings suggest that in sociology specifically and science generally the trend is toward greater collaborative scholarship. At the turn of the twentieth century, better than 90 percent of the articles appearing in major periodicals in physics, biochemistry, biology, and chemistry were sole authored. Today, over 95 percent of such articles are collaboratively published. Disciplines affiliated with the social and mathematical sciences have experienced similar monotonic increases in collaborative activity, albeit, at a slower rate. A discussion of plausible explanations is offered for this observed growth in scientific collaboration. 相似文献

We propose a new criterion for model selection in prediction problems. The covariance inflation criterion adjusts the training error by the average covariance of the predictions and responses, when the prediction rule is applied to permuted versions of the data set. This criterion can be applied to general prediction problems (e.g. regression or classification) and to general prediction rules (e.g. stepwise regression, tree-based models and neural nets). As a by-product we obtain a measure of the effective number of parameters used by an adaptive procedure. We relate the covariance inflation criterion to other model selection procedures and illustrate its use in some regression and classification problems. We also revisit the conditional bootstrap approach to model selection. 相似文献

The grief that certified nursing assistants (CNAs) experience following the deaths of nursing home residents has received scant attention in past research, particularly from an empirical standpoint. The purpose of this quantitative study was to investigate the grief experiences of CNAs in the nursing home setting and to identify and evaluate factors that may mediate or exacerbate grief. Participants (N=136) from 12 nursing homes completed self-administered surveys. Regression analyses revealed that CNAs with lower levels of perceived disenfranchised grief reported higher levels of personal growth, while CNAs with greater fear of death and those who experienced fewer deaths on the job reported higher levels of complicated grief. Practitioners and future researchers may benefit from these findings through the construction and implementation of interventions aimed at effectively enfranchising the grief experiences of this important group of healthcare workers. 相似文献
