Polygenic Influences on Pubertal Timing and Tempo and Depressive Symptoms in Boys and Girls

This study used polygenic scoring (PGS) to test whether puberty‐related genes were correlated with depressive symptoms, and whether there were indirect effects through pubertal maturation. The sample included 8,795 adolescents from the Avon Longitudinal Study of Parents and Children (measures of puberty drawn ages 8–17 years; of depressive symptoms at age 16.5 years). The PGS (derived from a genome‐wide meta‐analysis of later age at menarche) predicted boys’ and girls’ later pubertal timing, boys’ slower gonadal development, and girls’ faster breast development. Earlier perceived breast development timing predicted more depressive symptoms in girls. Findings support shared genetic underpinnings for boys’ and girls' puberty, contributing to multiple pubertal phenotypes with differences in how these genetic variants affect boys' and girls' development.     

Domesticating technology for shared success: collective enactments of World of Warcraft

In this paper, we analyse processes of domestication as collective enactments, using online game playing of World of Warcraft as a case. We study how groups of players – guilds – develop practices and sense-making with respect to the technologies they use in their shared endeavours in raids to battle monsters. Previous studies of domestication have mainly focused on single-actor strategies and relatively little attention have been given to the impact of concerns for particular domestication outcomes, for example in competitive situations or with goals related to efficiency. This paper contributes to domestication theory by analysing what we call collective domestication in a performance-oriented setting, to see how domestication may produce compatible outcomes for individuals that need to act together. The paper is based on a one-year participant observation and qualitative interviews with players. Three types of players were identified – hardcore, casual and moderate – representing three rationales of play: a high level of performance, social benefits, or a combination of the first two. In the analysis, we compare how these three types of player groups’ domesticated the game. A main finding is that collective enactments of technology need extensive managerial efforts unless the group share a coherent and uncontested rationale for playing, thus being a moral community.     

Reports of Conferences, Institutes, and Seminars

Late winter and early spring of 2009 was a busy conference time for librarians. Some of the conferences held during that time are reported herein: the American Library Association Midwinter Conference, January 23–28; Electronic Resources and Libraries (E&RL), February 9–12; the North Carolina Serials Conference, March 27; the New England Technical Services Librarians' (NETSL) Spring Conference, April 17; and the Technical, Electronic and Digital Services Interest Group (TEDSIG) Spring Meeting, April 24.     

Development and Lability in the Parent–Child Relationship During Adolescence: Associations With Pubertal Timing and Tempo

Adolescents' and parents' reactions to pubertal development are hypothesized to contribute to changes in family dynamics. Using 7‐year longitudinal data from the NICHD‐SECCYD (488 boys, 475 girls), we examined relations between pubertal development (timing, tempo) and trajectories (developmental change and year‐to‐year lability) of parent–child conflict and closeness from age 8.5 to 15.5 years. Changes were mostly characterized by year‐to‐year fluctuations—lability. Parent–child conflict increased and closeness decreased some with age. Pubertal timing and tempo were more consistently associated with lability in parent–child relationships than with long‐term trends, although faster tempo was associated with steeper decreases in parent–child closeness. Findings provide a platform for examining how puberty contributes to both long‐term and transient changes in adolescents' relationships and adjustment.     

Personalization and the Determination of News

This article addresses the relationship between the construction of news and personal experiences. Ethnography and narrative approaches are used to study a metropolitan newspaper where it is discovered that personalization contributes in large part to the decisions made by editors regarding whether or not an event is considered newsworthy. This discovery adds another dimension to the perspective that news is a social construction because it presents news as a decision-making process and highlights the human elements which contribute to the determination of news.     

Women's experiences of self-reporting health online prior to their first midwifery visit: A qualitative study

Background

Information and communication technologies are increasingly used in health care to meet demands of efficiency, safety and patient-centered care. At a large Danish regional hospital, women report their physical, mental health and personal needs prior to their first antenatal visit. Little is known about the process of self-reporting health, and how this information is managed during the client-professional meeting.

Bibliometric Network Analysis and Visualization for Serials Librarians: An Introduction to Sci2

ABSTRACT

Bibliometric data have the potential to inform collection development, describe institutional scholarship strengths and citation patterns, and suggest potential areas of research collaboration. This article introduces methods of using data from citation databases to generate bibliometric analyses of journal titles, subject matter, and coauthorship networks using the open software tool Science of Science (Sci2). These analyses can be used to enhance responsive institutional and network collecting and to connect users to additional research and publication partners.     

The Ancestry Question and Ethnic Heterogeneity: The Case of Arab Americans

This article uses US Census data to investigate change over time in Arab American profiles. In 2000, a higher proportion of children (0 to 13 years of age), women, and those who lived in the Northeast identified with an Arab/non‐Arab ancestry compared to an Arab‐only ancestry. In 1980 and 2000, a higher proportion (~90%) of those who identified with an Arab/non‐Arab ancestry was US born compared to only one‐half of those who identified with an Arab‐only ancestry. Those who identified with an Arab‐only ancestry were more likely to not be US citizens than those who identified with an Arab/non‐Arab ancestry. These findings suggest Arab Americans are a heterogeneous group.
