This paper presents the findings of a study comparing the well being and self-esteem of young adolescents (age 12-14) who were placed together with their siblings in residential facilities (intact care) in Israel and of youngsters who were placed without their siblings (separate care). The study examines the contribution of sibling relations, frequency of the meetings between the siblings, parental favoritism, age rank, time in care, self-esteem and perception of parents' economic status to the well being of the youngsters in the two groups. The findings show that the youngsters in intact care (N = 91) reported greater well being than those in separate care (N = 103), but have no other significant differences. Greater self-esteem and sibling closeness improved the well being of both groups of youngsters, but the other predictor variables functioned differently in the two groups. Greater frequency of meetings improved the well being only of the youngsters in intact care, while the other variables examined improved the well being only of those in separate care. Moreover, the examined variables accounted for a greater proportion of the variance in the youngsters' well being when the sibling was absent than when he or she was present. Practical implications are suggested.  相似文献

J.-C. Spender’s award-winning, knowledge-based theory of the firm is based on four premises: (1) The firm can be sufficiently understood as a system of knowledge, (2) explicit and implicit knowing can be clearly dissociated, (3) organizations are conceived as cognizing entities, and (4) intuition shaped by shared cultural practices is a superior source of managerial knowledge. This line of reasoning represents a social constructionist view of the enactment, transfer, and storage of knowledge according to which managerial knowledge is largely tacitly shaped by industry recipes and the firm’s socio-cultural conventions and other social processes. Although comprehensive in scope, we argue that a knowledge-based theory of the firm needs to integrate a cognitivist approach that includes the synergetic production of tacit and explicit knowledge, the role of reflective thinking in resolving strategic uncertainties, and the interaction between the individual and the social. This socio-cognitive theory of the firm posits that sustained competitive advantage of a firm is founded on the ability to align knowledge internally within the firm as well as externally with its stakeholders through the individual sense-making of feedback from other individuals.  相似文献

Nonlinear structural equation modeling provides many advantages over analyses based on manifest variables only. Several approaches for the analysis of latent interaction effects have been developed within the last 15 years, including the partial least squares product indicator approach (PLS-PI), the constrained product indicator approach using the LISREL software (LISREL-PI), and the distribution-analytic latent moderated structural equations approach (LMS) using the Mplus program. An assumed advantage of PLS-PI is that it is able to deal with very large numbers of indicators, while LISREL-PI and LMS have not been investigated under such conditions. In a Monte Carlo study, the performance of LISREL-PI and LMS was compared to PLS-PI results previously reported in Chin et al. (2003) and Goodhue et al. (2007) for identical conditions. The latent interaction model included six indicator variables for the measurement of each latent predictor variable and the latent criterion, and sample size was N=100. The results showed that PLS-PI’s linear and interaction parameter estimates were downward biased, while parameter estimates were unbiased for LISREL-PI and LMS. True standard errors were smallest for PLS-PI, while the power to detect the latent interaction effect was higher for LISREL-PI and LMS. Compared to the symmetric distributions of interaction parameter estimates for LISREL-PI and LMS, PLS-PI showed a distribution that was symmetric for positive values, but included outlying negative estimates. Possible explanations for these findings are discussed.  相似文献

Summary.  To enhance primary enrolment rates, many African countries have launched large teacher recruitment programmes in recent years. Given tight budgetary constraints, teachers are no longer employed in civil service positions, but on the basis of (fixed term) contracts typically implying considerably lower salaries and a sharply reduced amount of professional training. We analyse the effect of this change on educational quality in Niger, Togo and Mali, on the basis of very informative data, which are comparable across these countries. We use a variety of estimation techniques, including a non-parametric estimation of quantile treatment effects. Our results demonstrate that contract teachers tend to reduce inequalities in student outcomes. Overall, the effects are positive in Mali, somewhat mixed in Togo and negative in Niger. This ordering is consistent with theoretical expectations related to the manner in which contract teacher programmes were implemented differently in each of the three countries under study.  相似文献

Cooperative logistics relationships require the sharing of information, which must be enabled by the integration of disparate information systems across partners. In this article, we theorize business‐to‐business logistics relationships should be managed using cooperative and competitive postures. Based on data from 91 dyadic relationships using interorganizational information technology (IT), we find that performance gains accrue when parties share strategic information and customize IT; mutual trust enables IT customization and strategic‐information flows and equitable relationship‐specific investments positively impact IT customization, mutual trust, and performance. Among other scholarly and practical implications discussed, partners should compete on resources for IT customization and cooperate to share strategic information. Managers tend to think of relationships with firms as polar opposites and view them as entirely cooperative or entirely competitive. Our results support active balancing and understanding of both competitive and cooperative stances. Such an approach enables conditions for participation symmetry that yields greater performance gains.  相似文献

The paper examines the effect of income on mortality with respect to different health statuses and institutional characteristics of the health care system in the USA, Great Britain and West Germany. It is hypothesized that the nature of the theoretical contribution of income in explaining mortality risks changes on whether good or poor health is considered. Taking into account that the health care systems of the countries in question vary by their degree of household out-of-pocket expenditure, we expect an association between income and mortality that differs by country. The analysis is based on the German Socio-economic Panel (GSOEP), the British Household Panel Study (BHPS), and the Panel Study of Income Dynamics (PSID). The effect of income on mortality is found to be weakest when medical services are sought in the presence of poor health within the framework of a national health insurance that renders free primary health care (Great Britain, Germany). The effect is strongest when the provision of primary health care depends strongly on private expenditures (USA).  相似文献

In April 2020 a Group of Eight Taskforce was convened, consisting of over 100 researchers, to provide independent, research‐based recommendations to the Commonwealth Government on a “Roadmap to Recovery” from COVID‐19. The report covered issues ranging from pandemic control and relaxation of social distancing measures, to well‐being and special considerations for vulnerable populations. Our work focused on the critical needs of Aboriginal and Torres Strait Islander communities; this paper presents an overview of our recommendations to the Roadmap report. In addressing the global challenges posed by pandemics for citizens around the world, Indigenous people are recognised as highly vulnerable. At the time of writing Australia's First Nations Peoples have been largely spared from COVID‐19 in comparison to other Indigenous populations globally. Our recommendations emphasise self‐determination and equitable needs‐based funding to support Indigenous communities to recover from COVID‐19, addressing persistent overcrowded housing, and a focus on workforce, especially for regional and remote communities. These latter two issues have been highlighted as major issues of risk for Indigenous communities in Australia It remains to be seen how governments across Australia take up these recommendations to support Indigenous peoples' health and healing journey through yet another, potentially catastrophic, health crisis.  相似文献

Parents addicted to methamphetamine (“crystal meth”) are likely to be impaired in meeting parental responsibilities, and the developmental settings can be highly disadvantageous for children. Therefore, parenting by methamphetamine‐addicted mothers and fathers needs further exploration, while considering the impact on children affected by parental substance use. In our study, we analysed parenting practices and parental stress as well as children's behavioural problems using standardized assessments. The sample consisted of 87 methamphetamine‐addicted parents in recovery. We obtained data on parents' current substance use and on their psychological distress. Multiple regression analysis was performed to identify predictors of children's overall problems. Parents reported high levels of parental and psychological distress, even after achieving abstinence. Especially depressive perceptions of parenthood appeared problematic. While recovering from methamphetamine addiction, parents exhibited a precarious psychosocial situation and problematic parenting behaviour. Dysfunctional parenting practices were evident in both indifferent and overreactive tendencies. Children were at risk of behavioural and emotional problems. Variables associated with parenting showed significant predictive value for children's overall problems, beyond current substance use, and psychological distress. These findings are discussed in terms of a family‐oriented perspective in order to promote parenting capabilities of methamphetamine‐addicted parents and to prevent problematic development of their children.  相似文献
