The vowel space as sociolinguistic sign

This paper examines variation in vowel space area and its use in social meaning making. Among adolescents at a California high school, patterns of difference in vowel space correlate to social practices of exclusion in the partying scene, albeit alongside explicit discourses of high school social life as inclusive and fluid. I treat vowel space as a sociolinguistic sign, that is, a holistic semiotic resource at play in addition to (or in tandem with) individual segments. Though the semiotic potential of a given linguistic sign is no doubt shaped by large-scale patterns of variation, the particular manifestations of meaning making are best viewed at the community level alongside other day-to-day practices. Further, I suggest that linguistic practices of difference and discourses of sameness are not contradictory, but instead a feature of the semiotic landscape. I thus interpret this vowel space variation as stylistically meaningful within the context of social actors’ ideological orientation to social life.     

Domination and total domination in complementary prisms

Let G be a graph and be the complement of G. The complementary prism of G is the graph formed from the disjoint union of G and by adding the edges of a perfect matching between the corresponding vertices of G and . For example, if G is a 5-cycle, then is the Petersen graph. In this paper we consider domination and total domination numbers of complementary prisms. For any graph G, and , where γ(G) and γ _t (G) denote the domination and total domination numbers of G, respectively. Among other results, we characterize the graphs G attaining these lower bounds.

Physiological Regulation at 9 Months of Age in Infants Prenatally Exposed to Cigarettes

The primary purpose of this study was to examine the association between prenatal cigarette exposure and physiological regulation at 9 months of age. Specifically, we explored the possibility that any association between prenatal cigarette exposure and infant physiological regulation was moderated by postnatal environmental tobacco smoke (ETS) exposure or infant gender. We evaluated whether male infants with prenatal cigarette exposure or infants who were also exposed to ETS after birth had the highest levels of physiological dysregulation. Respiratory sinus arrhythmia (RSA) was obtained from 206 (142 exposed and 64 nonexposed) infants during a baseline period and during procedures designed to elicit both positive and negative affect. There was a significant suppression of RSA during the negative affect task for nonexposed infants, but not for exposed infants. Postnatal ETS exposure did not moderate this association; however, gender did moderate this association such that boys with prenatal cigarette exposure had a significant increase in RSA rather than the suppression seen among both nonexposed boys and girls. These results provide additional support for the idea that boys are particularly vulnerable to the effects of prenatal cigarette exposure.     

Social Work Faculty Development: An Exploratory Study of Non-Tenure-Track Women Faculty

Administrators of schools of social work are paying more attention to the changing roles and types of faculty in their institutions, particularly given the surge of non-tenure-track faculty in academia. This topic is timely as social work grapples with the divergent roles, structure, and demographic characteristics of non-tenure-track faculty compared to their tenured or tenure-track counterparts. This exploratory study presents data from non-tenure-track women faculty (N = 10) on how they experience professional development. In-depth, qualitative data was collected to answer the research question, What do faculty identify as the barriers, supports, and opportunities for professional development and job satisfaction? Results indicate that organizational climate and mentoring are barriers and facilitators of faculty development, and the subjective definition of faculty development varies.     

Cohabitation in Spain: No Longer a Marginal Path to Family Formation

Although many indicators reflect the marked retreat from marriage occurring in Spain since the 1980s, the diffusion of cohabitation has been slow. The confluence of very low and late fertility, latest‐late marriage, and low cohabitation has been largely regarded as defying the predictions of the second demographic transition and has fueled a debate over the distinctiveness of the Mediterranean model of family formation. Comparative analyses based on the Family and Fertility Survey documented the marginal role of cohabitation in Spain and in the rest of southern European countries by the mid‐1990s. In this research, the authors used more recent data from the 2006 Spanish Fertility, Family and Values Survey (N = 5,750) to reveal that cohabitation has spread significantly among younger cohorts and hence can no longer be considered as playing a marginal role in the family formation process.     

Trauma-informed care training in a child welfare system: Moving it to the front line

The use of trauma-informed practices in the child welfare system is critically important to prevent system-induced trauma and encourage timely assessment, triage and referral for care when indicated. Ultimately, such measures have the potential over time to decrease the risk for mental health problems in children exposed to a trauma. This study evaluates an initiative in Arkansas to train child welfare front-line staff members in trauma-informed care practices. We evaluated the impact of the training on knowledge and use of trauma-informed care practices among three types of child welfare staff (Caseworkers, Program Assistants and Other front-line staff). Results suggest that this training process was highly successful in improving knowledge of trauma-informed care practices, especially among staff with the least formal education and training. We also found a significant increase in staff use of trauma-informed care practices at the three-month follow-up with little difference observed across staff groups. Barriers that may prevent staff from full implementation of training concepts are described and strategies to address barriers are proposed.     

Risk Factors for Infant Mortality in Nineteenth-Century Sweden

This study examines risk factors for infant mortality using individual-level data from a sample of parishes in northern Sweden in the nineteenth century. Sweden is of particular interest because of its unusually regular pattern of infant mortality decline during the century. We follow a sample of women longitudinally through their successive pregnancies and observe the mortality experience of each child. Exploratory and multivariate logistic regression analyses reveal an important intra-familial dimension to infant mortality that appears from the early stages of a woman's reproductive career. In addition, multivariate analyses by birth-order group suggest that ignoring intra-familial correlations of infant mortality may result in incorrect inferences. Siblings' shared probabilities of dying as infants suggest that high-birth-order children were not necessarily disadvantaged in any systematic way.     

Lessons from a project to create performance measures for public health

This paper uses a specific example to illustrate complications that arise in formulating and implementing performance measures. The context of this demonstration is a Centers for Disease Control and Prevention (CDC)-funded project to explore the feasibility of performance measures developed at the national level for local sexually transmitted disease (STD) prevention and control programs. Grantees provided local data and reported on their experience in eliciting the data and using the results for program development. The experience of this project suggests that measures can be made operationally feasible and programmatically useful only if terminologies are subjected to extensive definition and clarification activities. These activities must include development of common language, mapping of workflows, and clarification of spheres of influence. Finally, performance measures must be used with some caution, as they often unintentionally capture extraneous program elements.
