Validity evidence of the Portuguese adaptation of the Ambivalent Sexism Inventory / Evidencias de validez de la adaptación portuguesa de la Escala de Sexismo Ambivalente

Abstract

Modern forms of sexism have promoted the development of new scales and evaluation tools. The Ambivalent Sexism Inventory (ASI) (Glick & Fiske, 1996) aims to assess sexism along two dimensions: hostile sexism and benevolent sexism. The aim of this study is to present evidence of the validity of the factor structure of the Portuguese version of the ASI by analysing its structure and its relationships with neosexism and social dominance. The sample consisted of 446 Portuguese participants (68.6% female) between 17 and 77 years old. Results confirmed the two-factor structure; however, the best fit was registered with a four-factor structure: one hostile factor and three benevolent factors. Both hostile and benevolent sexism were correlated with neosexism and social dominance orientation. Future research should explore the dimensionality of the scale based on a four-dimension structure and its relationship to others sexism issues.     

Missingness Amount and Mechanisms in Family Economic Stress Research: Mapping (Non)answers to Economic-Related Variables of Fathers,Mothers, and Emerging Adult Children

The percentage of missing data among economic-related items is likely to be particularly high. This study aimed at examining the amount, mechanisms, and variables associated with missingness of different family members participating in a family economic stress study. Portuguese emerging adults (N?=?418) and their parents (N?=?748) were required to answer objective and subjective economic items and complete measures assessing individual and family psychological functioning. Results showed that, for all participants, non-response was more likely to occur among objective economic items than among subjective ones. Children presented higher percentages of item/construct-level missingness than parents, which could reflect a reduced financial awareness on the part of these family members. Although the identification of mechanisms explaining missing data proved to be complex, family members’ missingness was associated with sociodemographic and psychological indicators, suggesting that non-answers do not occur purely by chance. Implications of these findings for further family economic stress research are discussed.

     

Healthy,Wealthy, Wise,and Happy? Assessing Age Differences in Evaluative and Emotional Well-Being Among Mature Adults from Five Low- and Middle-Income Countries

This study assesses the relationship between age and two dimensions of subjective well-being—evaluative and emotional—among mature adults from five low-and middle-income countries. We use data from the World Health Organization’s Study on Global AGEing and Adult Health to contrast the associations of age with subjective well-being when controlling only for gender with the corresponding partial associations when including a richer set of covariates. Adjusting only for gender, we find negative associations of age with evaluative well-being, while the corresponding age gradients for emotional well-being are relatively flat. By contrast, adjusting for further socio-demographic factors results in positive associations of age with both evaluative and emotional well-being. Oaxaca-Blinder decompositions allow us to explore the roles of two factors to account for any unadjusted age differences in subjective well-being: age-group differences in individual characteristics and life circumstances, and age-specific associations of individual characteristics and life circumstances with subjective well-being. While adverse circumstances such as poor health and low income contribute to lower levels of evaluative well-being among older adults, age per se is—ceteris paribus—positively associated with subjective well-being. Even in poorer countries, older age does not need to be a time of low subjective well-being. Policies aimed at preserving income and limiting or compensating old-age disability appear to be key for maintaining subjective well-being among older adults.

Determinants of maltreatment substantiation in a sample of infants involved with the child welfare system

Children under one year of age are highly vulnerable to child maltreatment, which can lead to serious immediate and long-term physical and mental health consequences. Child welfare workers encounter unique challenges when assessing allegations of maltreatment involving infants. This study identifies correlates of maltreatment substantiation in a sample of 793 infants less than one year of age investigated by child welfare. It is based on data from the 2003 Canadian Incidence Study of Reported Child Abuse and Neglect (CIS-2003), a national study of reports of child maltreatment. The analysis consisted of two stages. First, bivariate analyses were conducted using unadjusted odds ratios and chi-square tests on variables known to be associated with substantiation. In the second stage, a logistic regression was performed to examine these associations in a multivariate model.Multivariate findings suggest that certain vulnerabilities present in the primary caregiver, such as substance abuse and few social supports, as well as the child's positive toxicology at birth are associated with substantiated infant maltreatment. Exposure to domestic violence, which is reported mostly by the police, and physical harm stemming from maltreatment are strongly associated with substantiation, whereas reports of physical abuse and neglect have an inverse relationship. The authors discuss these results and implications for policy and programs.     

A Note on the Hodges–Lehmann Estimator and the Logistic Distribution

ABSTRACT

It is well known that the Hodges–Lehmann estimator is asymptotically efficient for the location parameter of the logistic distribution. In this article we give a simple and direct proof that this property also characterizes the logistic between all the symmetric location distributions under mild conditions. Using pseudolikelihood, we also show how to find from the Hodges–Lehmann estimator an asymptotically efficient estimator of the scale parameter of the logistic distribution.     

University environment and entrepreneurial intention: the mediating role of the components of the theory of planned behaviour / El entorno universitario y la intención emprendedora: el papel mediador de los componentes de la teoría de la acción planificada

Entrepreneurship contributes to job creation and economic development. Thus, it is important to promote entrepreneurial initiatives; universities play a key role in this regard. The psychosocial perspective can contribute a great deal to studying the antecedents that lead a person to become an entrepreneur, with the theory of planned behaviour (TPB) being the theoretical framework used the most to predict entrepreneurial intention. Based on the data collected in Spain as part of the international GUESSS project (Global University Entrepreneurial Spirit Students’ Survey) with a sample of 9,753 students, the influence of the university environment, the entrepreneurial environment and the perceived risk of entrepreneurship on entrepreneurial intention are analysed, both directly and as mediated by the three components of the TPB (attitudes towards entrepreneurship, subjective norms and entrepreneurial self-efficacy). The results show that the university environment is the antecedent with the greatest effect on entrepreneurial intention; therefore, it is recommended that entrepreneurship be promoted through initiatives and educational programmes in the university environment.     

Estimation of the Entropy Rate of a Countable Markov Chain

We consider here ergodic homogeneous Markov chains with countable state spaces. The entropy rate of the chain is an explicit function of its transition and stationary distributions. We construct estimators for this entropy rate and for the entropy of the stationary distribution of the chain, in the parametric and nonparametric cases. We study estimation from one sample with long length and from many independent samples with given length. In the parametric case, the estimators are deduced by plug-in from the maximum likelihood estimator of the parameter. In the nonparametric case, the estimators are deduced by plug-in from the empirical estimators of the transition and stationary distributions. They are proven to have good asymptotic properties.     

Clustering and classification problems in genetics through U-statistics

ABSTRACT

Genetic data are frequently categorical and have complex dependence structures that are not always well understood. For this reason, clustering and classification based on genetic data, while highly relevant, are challenging statistical problems. Here we consider a versatile U-statistics-based approach for non-parametric clustering that allows for an unconventional way of solving these problems. In this paper we propose a statistical test to assess group homogeneity taking into account multiple testing issues and a clustering algorithm based on dissimilarities within and between groups that highly speeds up the homogeneity test. We also propose a test to verify classification significance of a sample in one of two groups. We present Monte Carlo simulations that evaluate size and power of the proposed tests under different scenarios. Finally, the methodology is applied to three different genetic data sets: global human genetic diversity, breast tumour gene expression and Dengue virus serotypes. These applications showcase this statistical framework's ability to answer diverse biological questions in the high dimension low sample size scenario while adapting to the specificities of the different datatypes.     

Proactive coping with discrimination: A mediator between ethnic-racial socialization and Latinx youth's internalizing symptoms

There is a dearth of knowledge in the coping literature on how minoritized youth cope with racism-related stressors and the predictors of effective coping responses. This two-wave study examined the direct and indirect effects of ethnic-racial socialization on depressive and anxiety symptoms via proactive coping with discrimination in a community sample of 135 Latinx adolescents (M_age = 16, SD = 1.27; 59% female). Results indicate that cultural socialization was related to higher use of proactive coping with discrimination 6 months later, which in turn, was related to fewer depressive and anxiety symptoms. There were no direct or indirect effects between preparation for bias and mental health outcomes.
