Examining Two Theoretical Models Predicting American and Dutch Parents’ Mediation of Adolescent Social Media Use

The goal of the present study was to utilize two theoretical models, one based on a mediation approach and the other on the theory of planned behavior (TPB), to understand parents’ mediation of their adolescents’ social media use. Data were collected from parents of adolescents ages 10–18 in two countries, the United States (US) and the Netherlands. Results indicated significant differences between the two samples. Specifically, American parents reported more concern about adolescent social media use, more positive attitudes and perceived subjective norms to control adolescent use, and higher levels of active and restrictive mediation. In general, demographics and parental concern accounted for more explained variance in mediation behaviors among Dutch parents, and the TPB-based variables accounted for more explained variance among American parents. Results suggest important implications for the integration of different theoretical models to explain parent mediation behavior.     

Determinants of bilingualism among children: an econometric analysis

This paper analyzes the determinants of bilingualism (i.e., speaks a language other than English at home) among children age 5–18 years in the American Community Survey, 2005–2011. Two groups of children are considered: those born in the US (native born) and foreign-born children who immigrated prior to age 14 (the 1.5 generation). The analyses are conducted overall, within genders, and within racial and ethnic groups. Bilingualism is more prevalent if the parents are foreign born, less proficient in English, of the same ancestry (linguistic) group, and if the child lives in an ethnic (linguistic) concentration area. Although the effects are relatively smaller, a foreign-born grandparent living in the household increases child bilingualism, while a higher level of parental education tends to decrease it. Children of Asian and Hispanic origin are more likely to be bilingual than their white, non-Hispanic counterparts.     

Societal Norms Rather Than Sexual Orientation Influence Kin Altruism and Avuncularity in Tribal Urak-Lawoi,Italian, and Spanish Adult Males

Homosexual males could balance their low fitness by increasing benefits to relatives either through kin-directed altruism or by avuncularity (altruistic behavior toward the children of siblings). Evidence in support of kin selection and avuncularity includes the fact that homosexuals seem to be more empathic and altruistic than heterosexuals. Other studies have not confirmed behaviors that increase kin altruism in homosexuals. We explored altruistic behavior and avuncularity in a sample of 278 subjects, either homosexual or heterosexual, from three populations: Italian, Spanish, and Urak-Lawoi, a Southeast Asian tribal population. Among the Urak-Lawoi, the kathoeys, androphilic men who dress and behave as women, were compared with heterosexuals. All populations were rated for societal norms on the expression of affiliative behavior. No greater kin altruism or avuncularity among the kathoeys or in homosexuals in either Mediterranean population was found. Greater avuncularity and kin-directed altruism, independent of sexual orientation, were found among the Urak-Lawoi, and these traits were the least prevalent among the Italians, corresponding to different societal norms. The increase in kin altruism and avuncularity was associated in all males with societal differences and norms on general altruism toward nonkin children, suggesting it is not an adaptive design to maintain homosexuality in humans.     

Infants' Perception of Intonation: Is It a Statement or a Question?

The ability to distinguish phonetic variations in speech that are relevant to meaning is essential for infants' language development. Previous studies into the acquisition of prosodic categories have focused on lexical stress, lexical pitch accent, or lexical tone. However, very little is known about the developmental course of infants' perception of linguistic intonation. In this study, we investigate infants' perception of the correlates of the statement/yes–no question contrast in a language that marks this sentence type distinction only by prosodic means, European Portuguese (EP). Using a modified version of the visual habituation paradigm, EP‐learning infants at 5–6 and 8–9 months were able to successfully discriminate segmentally varied, single‐prosodic word intonational phrases presented with statement or yes–no question intonation, demonstrating that they are sensitive to the prosodic cues marking this distinction as early as 5 months and maintain this sensitivity throughout the first year. These results suggest the presence of precocious discrimination abilities for intonation across segmental variation, similarly to previous reports for lexical pitch accent, but unlike previous findings for word stress.     

Pedagogy of international social work: a comparative study in the USA,UK, and Georgia

The social work profession worldwide has been increasingly influenced by globalization and its effects on social issues that require social workers to be responsive and knowledgeable in addressing them. In recent years there has been an increased emphasis on the internationalization of the social work profession and education. With limited examples of international social-work-teaching methods discussed in the literature, there is also a lack of information obtained directly from students on methods of instruction that they most prefer and find beneficial. This collaborative, comparative project examined students' perceptions of methods that make teaching international social work successful at three universities in the United States, United Kingdom, and Georgia. While there were different preferences for content- and process-driven approaches in teaching, students' common interest was in gaining practice examples and exposure to real-life practice of international social work in their own and other countries. The findings suggest that international social work education needs to be more experiential and practice-based.     

Association between dietary phytoestrogens intakes and prostate cancer risk in Sicily

Objective: In this study we aimed to investigate the association between dietary phytoestrogen consumption and prostate cancer in a sample of southern Italian individuals.

Methods: A population-based case-control study on the association between prostate cancer and dietary factors was conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy (Registration number: 41/2015). A total of 118 histopathological-verified prostate cancer (PCa) cases and a total of 222 controls were collected. Dietary data was collected by using two food frequency questionnaires.

Results: Patients with PCa consumed significantly higher levels of phytoestrogens. Multivariate logistic regression showed that lignans (Q[quartile]4 vs. Q1, OR [odds ratio]?=?4.72; p?p?p?p?p?p?p?Conclusion: We found of an inverse association between dietary isoflavone intake and PCa, while a positive association was found with lignans intake.     

The Construction and Mobilization of Unemployed Interests: The Case of Sweden in the 1990s

In this paper, using a case of unemployed mobilization in Sweden in the 1990s, we examine the interpretive process by which unemployment interests emerge and evolve in public interactions with other political actors, especially unions, and argue that unemployed mobilization episodes cannot be fully understood without attention to interpretive processes. More specifically, we show how unemployed interests during the unemployment crisis in the 1990s initially were aligned with the labor movement at large, later became aligned with unions against the Social Democrats, and eventually gave rise to an independent federation of unemployed groups, which subsequently collapsed.
