The Rise in Single-Mother Families and Children’s Cognitive Development: Evidence From Three British Birth Cohorts

This article assessed changes in the association between single motherhood and children’s verbal cognitive ability at age-11 using data from three cohorts of British children, born in 1958 (n = 10,675), 1970 (n = 8,933) and 2000 (n = 9,989), and mediation analysis. Consistent with previous studies, direct effects were small and insignificant. For those born in 1958 and 1970 indirect effects, operating through reduced economic and parental resources, were associated with −.107-SD to −.156-SD lower attainment. Differences between the two cohorts, and by children’s age when parents separated, were insignificant. For the 2000 cohort, effect sizes for children born to single mothers did not change significantly (−.112-SD) but attenuated for children whose parents separated in early childhood (−.076-SD) or while of school age (−.054-SD).     

Constraints on conceptual development: a case study of the acquisition of folkbiological and folksociological knowledge in Madagascar

How different are the concepts held by children who grow up in a North American middle class neighborhood and by children who grow up in a rural Malagasy fishing village? By probing Malagasy children's and adults' conceptual representations of human and animal kind, biological inheritance, innate potential and family relations, the studies presented in this Monograph address current debates about the acquisition and the nature of concepts in the domains of folkbiology and folksociology. Cross-cultural and developmental studies of this kind bear on the hypothesis that conceptual development in these domains is supported and constrained by innate conceptual content. If so, one would expect cross-cultural universality in the relevant adult concepts and their early emergence in childhood regardless of widely different input conditions. We chose to conduct these studies among the Vezo of Madagascar because the ethnographic literature has attributed to them folkbiological and folksociological theories that are radically different, even in commensurable, with those of North American adults. Vezo therefore provide a challenging test for the innate conceptual constraints hypothesis.Four studies probed aspects of biological and sociological reasoning of Vezo children, adolescents and adults through a number of adoption scenarios. Despite ethnographic reports to the contrary, we found cross-cultural convergence in adult concepts of biological inheritance, but the pattern of development of this concept differed greatly from that seen in North America. Moreover, in agreement with the ethnographic literature, we found that Vezo adults have constructed a distinctive theory of social group identity. However, we found that children's reasoning in this domain is under the influence of endogenous constraints that are overturned in the course of development. Finally, we found cross-cultural convergence in adults' concept of species kind, as well as evidence for the early emergence of this concept. In light of these findings, we discuss the nature of the constraints on children's conceptual representations, the developmental process through which the adults' concepts are constructed, and relations between Vezotheories of folkbiology and folksociology.     

Scientific Teaching Targeting Faculty from Diverse Institutions

We offered four annual professional development workshops called STAR (for Scientific Teaching, Assessment, and Resources) modeled after the National Academies Summer Institute (SI) on Undergraduate Education in Biology. In contrast to the SI focus on training faculty from research universities, STAR''s target was faculty from community colleges, 2-yr campuses, and public and private research universities. Because of the importance of community colleges and 2-yr institutions as entries to higher education, we wanted to determine whether the SI model can be successfully extended to this broader range of institutions. We surveyed the four cohorts; 47 STAR alumni responded to the online survey. The responses were separated into two groups based on the Carnegie undergraduate instructional program categories, faculty from seven associate''s and associate''s-dominant institutions (23) and faculty from nine institutions with primarily 4-yr degree programs (24). Both groups expressed the opinion that STAR had a positive impact on teaching, student learning, and engagement. The two groups reported using techniques of formative assessment and active learning with similar frequency. The mix of faculty from diverse institutions was viewed as enhancing the workshop experience. The present analysis indicates that the SI model for training faculty in scientific teaching can successfully be extended to a broad range of higher education institutions.     

A Theology of Inferiority: Is Christianity the Source of Kinesiology's Second-Class Status in the Academy?

What influence has Christianity had on kinesiology and physical education's status in the Academy? Conventional wisdom within kinesiology often seems to argue that the influence has been quite negative. These critics allege that Christianity is a fundamentally dualistic religion. They allege that, at its best, Christianity is suspicious of the body and that, at its worst, Christianity openly proclaims that the body is evil. Despite the popularity of such assertions, there is abundant evidence in both historical and contemporary theology to show that Christianity is a religion in which corporeality plays a central, defining, and positive role. From Saint Paul to Saint Augustine, from Saint Aquinas to the present day, it has been a central doctrine of Christianity that the human body is good and, furthermore, that corporeality plays a vital role in salvation. Consequently, any blanket assertion that Christianity is the source of physical education and kinesiology's ills is fundamentally misleading and mistaken.     

LGBTQ+ health research guides at North American health sciences libraries: a survey and content analysis

Objectives:Current literature recommends online research guides as an easy and effective tool to promote LGBTQ+ health information to both health care providers and the public. This cross-sectional study was designed to determine how extensive LGBTQ+ health guides are among hospital and academic libraries and which features are most prevalent.Methods:In order to locate LGBTQ+ health guides for content analysis, we searched for guides on the websites of libraries belonging to the Association of Academic Health Sciences Libraries (AAHSL) and the Canadian Association of Research Libraries (CARL). Additionally, we searched the Springshare interface for LibGuides with the word “health” and either “LGBT” or “transgender.” Content analysis was performed to identify major characteristics of the located guides, including target audience and the information type provided.Results:LGBTQ+ research guides were identified for 74 libraries. Of these, 5 were hospital libraries, and the rest were academic libraries. Of 158 AAHSL member libraries, 48 (30.4%) had LGBTQ+ guides on their websites. Nearly all guides (95.9%) provided general LGBTQ+ health information, and a large majority (87.8%) also had information resources for transgender health. Smaller percentages of guides contained information on HIV/AIDS (48.6%) and women''s health (16.2%).Conclusions:Even though literature recommends creating LGBTQ+ health guides, most health sciences libraries are missing an opportunity by not developing and maintaining these guides. Further research may be needed to determine the usage and usefulness of existing guides and to better identify barriers preventing libraries from creating guides.     

Parasocial Breakup and Twitter: The Firing of Barb Abney

Audiences can and do form parasocial relationships with media personalities. Media personalities, programs, and stations can use social media to enhance this relationship. More and more stations and programs are using social media to cultivate parasocial relations, but the consequences of this cultivation are largely understudied in terms of parasocial responses. This paper examines the fallout on social media of the loss of a parasocial relationship (called “parasocial breakup”) with a large market radio DJ who is removed from the air. The results confirm the presence of a parasocial relationship, feelings of parasocial breakup, and the consequences of these parasocial disruptions on station brand identity.

Poor and Rich: Student Economic Stratification and Academic Performance in a Public Research University System

One sees various efforts in developed as well as in developing economies to seek a greater participation of lower‐income students in their nation's leading universities. Once lower‐income students do enroll in a highly selective institution, what happens to them? How well do they do academically when compared to their more wealthy counterparts? How integrated are they into the academic community and in their satisfaction with their choice and sense of support by the institution and fellow students? These are crucial questions, if and when élite universities in various parts of the world become more representative of their general population; the stated desire of most of these institution, virtually all of which are nationally funded entities that must justify their public subsidies. This paper explores the divide between poor and rich students, first comparing a group of selective US institutions and their number and percentage of Pell Grant recipients and then, using institutional data and results from the University of California, Student Experience in the Research University Survey (SERU Survey), presenting an analysis of the high percentage of low‐income undergraduate students within the University of California system; who they are, their academic performance and quality of their undergraduate experience.
