Research examining how sexual minorities characterize love within same-sex relationships is scarce. In this study, we examined the validity of Sternberg's Triangular Theory of Love in a sample of sexual minority male youth (N = 447). To test the adequacy of the theory for our population, we examined the psychometric properties of the Triadic Love Scale (TLS) and tested whether the three underlying constructs of the theory (Intimacy, Passion, and Commitment) emerged when participants were asked to consider their ideal relationship with another man. Using confirmatory factor analysis (CFA), we found support for the three-factor solution to characterize sexual minority male youths' ideal romantic relationship, after minimizing item cross-loadings and adapting the content of the Passion subscale. We discuss the implications of our findings regarding the measurement of the TLS among sexual minority male youth and propose ways to enhance its measurement in future research. 相似文献

Research has demonstrated the importance of job characteristics to explain work-to-family enrichment (WFE) and the value of this enrichment to explain employees’ wellbeing. However, there is no comprehensive framework to explain the relationship between these variables. This study uses the Job Demands-Control-Support model as a guiding framework, and examines the relationship between these job characteristics and WFE and, more interestingly, the WFE as a mechanism for explaining the relationship between job characteristics and employees’ well-being. Furthermore, we analyzed the relationship of employees’ perceptions of High Performance Work System (HPWS) with job characteristics. With a sample of 1,390 employees from a Portuguese bank, job demands were found to be negatively related to WFE while autonomy and supervisor support displayed a positive relation. We also observed that WFE is an important mechanism to explain the relationship between these job characteristics and employees’ well being. As expected, HPWS was a relevant organizational characteristic to explain job characteristics, however, we observed that it was also directly related to WFE. 相似文献

This article provides evidence that many Central Americans who have joined the migrant caravans to the north manifest a profound discontent with the political institutions of their home countries. It is based on surveys with migrants in refugee centres, compared with similar data from the AmericasBarometer survey, and complemented with contextual qualitative data on the experience of immigrants passing through Mexico. The article shows that several Central Americans in route to the north do not trust their political institutions and express little support for their political system. It demonstrates that in contexts where economic instability, rampant crime, and environmental uncertainty prevail, many citizens keep exiting their countries under the conviction that government institutions have lost the capability to protect them from existential threats. 相似文献

This paper presents data from a unique programme evaluation of the parenting programme titled ‘Learning together, growing as a family’ applied in 14 cities in Spain and targeting families at risk of neglectful behaviour. The programme evaluation is based on the voices of children using the qualitative methodology of art-based research. Eighty-six children 6–12 years of age were interviewed in groups. The outcomes of the evaluation reveal that children perceive improvements in the parental competencies of their parents and in themselves and that these changes serve as a catalyst for positive family change. 相似文献

On backbone coloring of graphs 总被引:1,自引:0,他引:1

Let G be a graph and H a subgraph of G. A backbone-k-coloring of (G,H) is a mapping f: V(G)→{1,2,…,k} such that |f(u)−f(v)|≥2 if uv∈E(H) and |f(u)−f(v)|≥1 if uv∈E(G)\E(H). The backbone chromatic number of (G,H) is the smallest integer k such that (G,H) has a backbone-k-coloring. In this paper, we characterize the backbone chromatic number of Halin graphs G=T∪C with respect to given spanning trees T. Also we study the backbone coloring for other special graphs such as complete graphs, wheels, graphs with small maximum
average degree, graphs with maximum degree 3, etc. 相似文献

The Comprehensive Caregiver Choices Program provided support for employee caregivers of elderly people for employees at a hospital in Fort Worth, Texas. Key informant interviews and focus groups provided direction for program development and implementation. A full-time MSW and professionals with expertise in gerontology/geriatrics provided education and care coordination services to caregivers. Approximately 4% of the hospital's workforce participated in the program. Attendees evaluated educational sessions and follow-up interviews were conducted with program participants. Caregiver support programs must continue to seek innovative and creative marketing and service delivery methods to reach out and assist working caregivers in need of support. 相似文献

The general aim of manifold estimation is reconstructing, by statistical methods, an m-dimensional compact manifold S on d (with m≤d) or estimating some relevant quantities related to the geometric properties of S. Focussing on the cases d=2 and d=3, with m=d or m=d?1, we will assume that the data are given by the distances to S from points randomly chosen on a band surrounding S. The aim of this paper is to show that, if S belongs to a wide class of compact sets (which we call sets with polynomial volume), the proposed statistical model leads to a relatively simple parametric formulation. In this setup, standard methodologies (method of moments, maximum likelihood) can be used to estimate some interesting geometric parameters, including curvatures and Euler characteristic. We will particularly focus on the estimation of the (d?1)-dimensional boundary measure (in Minkowski's sense) of S. It turns out, however, that the estimation problem is not straightforward since the standard estimators show a remarkably pathological behaviour: while they are consistent and asymptotically normal, their expectations are infinite. The theoretical and practical consequences of this fact are discussed in some detail. 相似文献

In this article, we propose a nonparametric method to test for symmetry in bivariate data. By using the extension of Fisher's exact treatment for 2 × 2 contingency tables proposed by Freeman and Halton (1951), we can test the hypothesis of equal distribution for two samples of integer valued variables. Then, by counting the number of observations belonging to each cell of a symmetric, appropriately built grid, we can produce the two samples of integers required to use this test for equal distribution. The resulting test for symmetry is potentially extendible to higher dimensions. A simulation study is performed to compare with some known tests (Bowker, 1948; Hollander, 1971; and its improvement given in Krampe and Kuhnt, 2007). Our proposal represents a competitive option as a test for symmetry. 相似文献

Mixtures of skewed distributions (univariate and bivariate) provide flexible models. An alternative modeling approach involves distributions with skewed conditional distributions and mixtures of such distributions. We consider the interrelationships between such models. Examples are provided to show that several skewed distributions already considered in the literature can be viewed as having been constructed via a combination of mixing and skewing. 相似文献

This article considers a generalization of the functional linear regression in which an additional real variable influences smoothly the functional coefficient. We thus define a varying-coefficient regression model for functional data. We propose two estimators based, respectively, on conditional functional principal regression and on local penalized regression splines and prove their pointwise consistency. We check, with the prediction one day ahead of ozone concentration in the city of Toulouse, the ability of such nonlinear functional approaches to produce competitive estimations. 相似文献
