Latin American immigrant women and intergenerational sex education

People of Latin American descent make up the largest and fastest-growing minority group in the USA. Rates of pregnancy, childbirth, and sexually transmitted infections among people of Latin American descent are higher than among other ethnic groups. This paper builds on research that suggests that among families of Latin American descent, mothers have a particularly strong influence on the sexual attitudes and behaviours of their children, yet that parents of Latin American descent communicate less with their children about sex than parents of other ethnic groups. It examines the messages about sex women received as children in their countries of origin, and how these messages and their views of the USA influence the sexual education women provide for their children. On the basis of data from focus groups, we suggest that, in spite of the persistence of sexual silence, some women's self-reflective analyses of their own sexual education as well as their views of the USA as a sexually more open society contribute to their views of silence as dangerous and trigger more open communication with sons and daughters. Mothers hope to break the cycle of unwanted pregnancy by speaking with daughters about the consequences of menstruation and with sons about contraception.

Modeling Ability Differentiation in the Second-Order Factor Model

In this article we present factor models to test for ability differentiation. Ability differentiation predicts that the size of IQ subtest correlations decreases as a function of the general intelligence factor. In the Schmid–Leiman decomposition of the second-order factor model, we model differentiation by introducing heteroscedastic residuals, nonlinear factor loadings, and a skew-normal second-order factor distribution. Using marginal maximum likelihood, we fit this model to Spanish standardization data of the Wechsler Adult Intelligence Scale (3rd ed.) to test the differentiation hypothesis.     

Professional learning during a schools–university partnership Master of Education course: teachers’ perspectives of their learning experiences

An extensive body of research has indicated the benefits of collaborative, contextualised and enquiry-based learning for teachers’ professional development and school improvement. Yet professional learning is also known to be constrained by a number of factors, including the organisational limitations of schools, conflicting cultural practices and wider political demands. Schools–university partnerships have been developed to overcome some of these difficulties by transcending particular school contexts and offering alternative theoretical and practical perspectives. The complex combination of motivations, backgrounds and working contexts in such partnership work calls for attention to the individual and collective learning experiences of those involved, including the ways in which school and university contexts are, or could be, effectively bridged. This paper focuses on understanding the learning experienced by a cohort of teachers and school leaders involved in a two-year schools–university partnership Master of Education (M.Ed.) course in England. A mixed group of 15 experienced primary and secondary teachers and school leaders reflected on their learning at five points of time during and shortly after completing their M.Ed. course. Qualitative analysis of the group’s interview responses and reflective writing led to the identification of six related aspects of personal and professional learning experience: being a learner; learning as part of professional practice; widening repertoire; changing as a learner; personal growth; and critically adaptive practice. The identification and visual representation of these aspects of experience emerging within the group offers useful insight into teachers’ perspectives on learning in school and university contexts and their experiences of progression over time. We conclude that more explicit and central attention to the professional and personal learning elements of schools–university partnerships can help to resolve some of the binary ‘theory–practice’ tensions that have been extensively discussed in relation to partnership programmes and teacher professional development. There is a need to acknowledge variation in teachers’ learning experiences within schools–university partnerships, bearing in mind the ongoing nature of this reflective process with each new group of school and university colleagues. Analysis of participants’ learning experiences in school and university contexts also draws attention to the wider structures, values and cultures that influence, and are influenced by, schools–university partnership work.     

The dimensions of research in undergraduate learning

Most Australian Universities offer a selection of research-intensive pathways at the graduate level, which provides opportunities for independent inquiry and intellectual autonomy. Undergraduate students, however, are somewhat short-changed in their experience in research. They are exposed to a variety of areas and disciplines, which forms a general cluster of knowledge, but students graduate without obtaining the skills associated with research and inquiry. Digital communication networks and the ways in which information is disseminated in modern society play an important role in the way people live and learn. At the same time, younger generations are emerging with greater skills in digital literacy, which bears an impact on how knowledge is produced and information is shared. This prompts to question, are undergraduate students acquiring the generic attributes that will help them to cope with the complexities of an information-driven society? The following article is based on the premise that undergraduate students need to be empowered to construct their own knowledge as potential producers rather than mere consumers of knowledge. It provides a synthesis of cross-disciplinary perspectives and educational debates that support the argument for, and benefits of, providing research-enriched learning for undergraduate students. This article adopts a framework for the dimensions of research in undergraduate learning. The different models presented in this article aim to illustrate the various ways that research can be integrated with teaching to benefit learning.

The Philippine–American War and the American Debates about the Necessity and Legality of the “Water Cure,” 1901–1903

Abstract

This essay provides a critical genealogical study of the “water cure” controversies that took place during the Philippine–American War. The author extends the work of Foucault and Agamben to argue that a biopolitical review of this controversy illustrates how many of the legal and cultural arguments used to legitimate the water cure have resurfaced in contemporary debates about waterboarding and enhanced interrogations techniques. The essay also illustrates how anti-imperialists and other critics of Theodore Roosevelt's administration tried to use these water-cure debates as discursive vehicles for complaining about the systematic abuse of Filipinos during the Philippine “Insurrection.”

From shanzhai chic to Gangnam style: seven practices of cultural-economic mediation in China and Korea

ABSTRACT

This paper examines the social construction of ‘fashionability’ – namely, what is ‘desirable’ and ‘fashionable’ – with reference to the concept ‘cultural mediators’ that foregrounds agency, negotiation and the contested practices of market actors in cultural production. It zeroes in on the cultural mediators’ attitudes and positions in the two markets by drawing on 25 in-depth interviews with industry veterans. It shows that the mediators in South Korea and China increasingly occupy hybrid occupational roles and social positions across industries and sectors yet achieve limited success in countering the status quo of Western fashion through mediation. The analysis contributes to the literature with a categorisation of seven mediation practices that shape the valuation of fashion products (i.e. ‘fashionability’) in two ways. Empirically, this categorisation illuminates how cultural mediators make reference habitually to the broader social and cultural contexts to co-construct cultural-aesthetic objects. Theoretically, it advances a cultural-economic approach to the understanding of cultural mediation and challenges the reductionist viewpoint of actor–network theory through the notion of a matrix of cultural-economic agency.     

Work–family conflict,relational turbulence mechanisms,conflict tactics and marital satisfaction*

ABSTRACT

This study examined how work–family conflict (WFC) is associated with mechanisms of relational turbulence, conflict tactics, and marital satisfaction. Six hundred and thirty-three married workers completed an online survey. Family interference with work and spouses’ work interfering with one’s family predicted greater relational uncertainty and interference from partners, whereas one’s own work interfering with family did not predict these mechanisms of turbulence. All three sources of relational uncertainty, and interference from partners, predicted increased avoidance and distributive tactic use. Facilitation from partners predicted increased use of integrative tactics. Finally, relational uncertainty, interference from partners, and distributive conflict tactics partially mediated the associations of WFC with marital satisfaction.
