Proportions of a total, including social network compositions (proportions of partner, family, friends, etc.) lie in a restricted space, which challenges statistical analysis. Network compositions can be both dependent and explanatory variables and are usually measured with error by survey instruments. Structural equation models make it possible to correct measurement error bias. Coenders et al. (2011) fitted a factor analysis model to transformed network compositions. In this article, we use another transformation called an isometric log-ratio and we extend the model to include predictors and outcomes. The findings and hypotheses in the literature can be reformulated with isometric log-ratios in a more interpretable manner. For instance, we find relationships of gender with partner support, of education and extraversion with friend support, and of family support with tie multiplexity and closeness. 相似文献
The current study evaluates three hypothesized models on subjective well-being, comprising life domain ratings (LDR), overall
satisfaction with life (OSWL), and overall dissatisfaction with life (ODWL), using structural equation modeling (SEM). A sample
of 1,310 volunteering students, randomly assigned to six conditions, rated their overall life (dis)satisfaction and their
(dis)satisfaction with six different life domains. Each condition used one of six response formats, differing in (1) orientation
(horizontal vs. vertical), and (2) anchoring (0 to 10, −5 to +5, and Not numbered). The results of a confirmatory factor analysis
(CFA) support a six-factor model of LDR based on satisfaction or dissatisfaction items. However, our findings indicate that
the kind of response format used to obtain satisfaction and dissatisfaction ratings can affect the factor loadings. Our results
indicate that the proposed models of OSWL, and ODWL fit the data well, and are able to predict OSWL and ODWL, respectively.
Moreover, among six life domains, which figure as the latent variables in our models, psychological well-being was found to
be the strongest predictor of both OSWL and ODWL.
Recent empirical literature has seen many multidimensional indices emerge as well-being or poverty measures, in particular
indices derived from principal components and various latent variable models. Though such indices are being increasingly and
widely employed, few studies motivate their use or report the standard errors or confidence intervals associated with these
estimators. This paper reviews the different underlying models, reaffirms their appropriateness in this context, examines
the statistical properties of resulting indices, gives analytical expressions of their variances and establishes certain exact
relationships among them.

To ameliorate high turnover in child welfare, researchers have attempted to identify factors that lead to undesirable turnover. While this has been studied extensively, little attention has been paid to turnover based upon job roles. Like social workers in child welfare, the field of child care also experiences high turnover. Child care workers employed in child welfare settings are no exception. The current study seeks to understand differential factors that impact intent to leave for preventive and child care workers employed in child welfare agencies.
Materials and methods
Data for prevention workers (n = 538) were obtained from all preventive service programs under contract with the City. Data for child care workers (n = 222) were obtained from three voluntary agencies located elsewhere in the State. The instrument was a modified version of a survey developed to examine job satisfaction and potential turnover among public child welfare workers. Domains measured included job satisfaction, intention to leave, career commitment, and agency investment. Data were analyzed using bivariate analysis and Structural Equation Modeling (SEM).
Results
Child care workers had more positive perceptions of child welfare and planned to stay in child welfare longer. Despite this, prevention workers felt more invested in their work. Child care and prevention workers had different levels of satisfaction with their jobs although overall job satisfaction did not differ nor did their intention to leave. Tenure at the agency was predictive of career investment. Investment, perceptions of child welfare, satisfaction with nature of work, and contingent rewards were associated with career commitment. Commitment and satisfaction with supervision were the greatest predictors of intention to leave.
Discussion
There is a gap in literature addressing child care workers in child welfare, and future study of this group is needed. Child care workers are just as likely to intend to leave their jobs as prevention workers. For both groups, it appears that investment in their jobs increases commitment to the field which reduces intention to leave. 相似文献
Liberal enthusiasm over the arrival of a ‘post-racial’ era in the USA found ecstatic release at the 2008 election of the first African-American to the presidency. Several years have passed since that event, and the idea of ‘post-race’ remains a potent, if uneasy, keyword within the national imaginary. Authorizing ‘official antiracisms’ of our day, post-race sanctions the governmentalities of racial neoliberalism, and forecloses alternative paradigms for antiracist struggle. Equally, it registers as a cruel joke of sorts, turning on studied denials of abiding inequalities and open to the lash of ridicule and scorn. At once absurd and alluring, post-race reveals the cultural career of a keyword marked by power and authority as well as tenacious counter-claims that show up its conceits and specious allure.
A rich body of scholarship has emerged in recent years to unpack the meanings and implications of the term. These works typically take the Obama moment, unprecedented and consequential, as a key signifying theatre. This essay, however, begins elsewhere, suggesting instead that the 2008 victory constitutes a denouement, a narrative climax to epistemic struggles that shaped racial discourse over decades prior to and, indeed, anticipating Obama's arrival as post-racial icon. Offering a genealogical pre-history of post-race, the analysis uses the analytical lens of ‘bricolage’ to trace a range of articulations over a 40-year span that concludes with Obama's 2008 victory. The essay maps the riotous ascendance of post-race as well as its faltering claims to authority to reveal the conditions of possibility that gave rise to, and continue to provide traction for, the idea of the post-racial. Highlighting key epistemological shifts ushered in by the concept, the essay substantiates the terms of a third ‘racial break’ that works to foreclose all but those antiracist projects that serve the incentives of neoliberal capital. 相似文献
