Social,Relational and Network Determinants of Unprotected Anal Sex and HIV Testing Among Men Who Have Sex with Men in Beirut,Lebanon

Objectives: We examined the social, relational and network determinants of condom use and HIV testing among men who have sex with men (MSM) in Beirut. Methods: Two-hundred thirteen men were recruited via respondent driven sampling and administered a survey. Results: Sixty-four percent reported unprotected anal intercourse (UAI), including 23% who had UAI with unknown HIV status partners (UAIU); 62% of participants had tested for HIV. In multivariate analysis, being in a relationship was associated with UAI and HIV testing; lower condom self-efficacy was associated with UAIU and HIV testing; gay discrimination was associated with UAIU; MSM disclosure was associated with UAI, UAIU and HIV testing; and network centralization was associated with HIV testing. Conclusions: Multi-level social factors influence sexual health in MSM.     

Measuring community mobilization in the Seattle Minority Youth Health Project.

This article assesses the validity and reliability of the approach used to measure community mobilization in the Seattle Minority Youth Health Project (MY Health), a neighborhood-based program to prevent drug use, violence, teen pregnancy, and sexually transmitted diseases (STDs). Two constructs were measured: neighborhood cooperation in solving problems, and sense of pride and identification with the neighborhood. The convergent validity of the measurement approach was assessed by comparing several independent measures of community mobilization generated from surveys of key neighborhood leaders, youth, and parents. For the neighborhood cooperation construct, correlations were uniformly positive across measures from different surveys and statistically significant about a quarter of the time. The correlations for the neighborhood pride construct were weaker and generally not statistically significant. Interrater reliability was low for all of the surveys, possibly reflecting varying ideas about what community mobilization meant among survey respondents.     

Neighbourhood and preventive strategies with children and families: what works?

This paper argues that the 1989 Children Act has provided a poor context for discussing ‘prevention’. The Act has not helped the development of either a proper understanding of childhood disadvantages or policies to deal with it. This paper presents a fresh perspective on ‘prevention’ in the context of Government initiatives such as Sure Start, and argues for analysis of neighbourhood disadvantages and neighbourhood-based policies. The ‘geography of disadvantage’ has to be understood as well as the facts of disadvantage, that is, the concentrations and persistence of variations in income, health, and educational outcomes as they affect children. Examples of early years programmes and projects are reviewed for their impact on disadvantaged children and their families. Copyright © 1999 John Wiley & Sons, Ltd.     

The Production of Several Items in a Single Facility with Linearly Changing Demand Rates

In this paper we extend the ELSP model to allow for linearly changing demand rates over a fixed planning horizon. This extension of the ELSP research provides a model that can be used in coordinating the production and marketing planning activities in a firm. The model allows the user to evaluate the impact of changes in product demand on production costs and customer service. We solve the model using a standard nonlinear programming package (MINOS) and show through examples based on actual production data how the model can be used to support coordinated production and marketing planning.     

Die symbolische Macht der Individualisierung und der Kampf um die Kritik

In the article we highlight an aspect of the crisis of criticism which we call ??speechlessness of criticism??. The heterogeneous criticism cannot be bundled up to a critical story any more. A common language with explicatory pictures and grammars is missing. Two explanations are offered for the ??speechlessness?? of criticism: the changes of the normative power of justification orders and the individualisation process. Both developments are a symbolic power which can explain the speechlessness of the criticism of capitalism at least partially. After the sketch of the symbolic power of the legitimation order of project and individualisation, starting points for a renaissance of criticism are analysed. Finally we explore the relevance of a reflexive combination of critical sociology and sociology of criticism for the concept of a critical sociology of criticism.     

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.     

Asymmetries in the opportunity structure. Intergenerational mobility trends in Europe

It remains unclear whether social mobility is increasing in the advanced nations. The answer may depend on mobility patterns within very recent birth cohorts. We use the inter-generational module in the 2005 EU-SILC which allows us to include more recent cohorts. Comparing across two Nordic and three Continental European countries, we estimate inter-generational mobility trends for sons both indirectly, via social origin effects on educational attainment, and directly in terms of adult income attainment. In line with other studies we find substantially more mobility in Scandinavia, but also that traditionally less mobile societies, like Spain, are moving towards greater equality. We focus particularly on non-linear relations. Most interestingly, we reveal evident asymmetries in the process of equalizing life chances, in Denmark. The disadvantages associated with low social class origins have largely disappeared, but the advantages related to privileged origins persist.     

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.

Staffing-Related Deficiency Citations in Nursing Homes

There is evidence that staffing characteristics influence quality of care in nursing homes. Federal and state surveyors conduct inspections of homes to assess their compliance with regulatory standards, including requirements related to staffing. Deficiency citations are issued when these standards are not met. This article examines the relationship between operational, facility, and market characteristics and organizational performance measured as staffing-related deficiency citations. Online Survey Certification of Automated Records (OSCAR) data from 2000 through 2007 were used with multinomial logistic regression analyses to identify factors associated with deficiency citations for staffing. Chain members and facilities with poor quality of care were more likely to receive deficiency citations for staffing. Greater bed count and competition between nursing homes were associated with a decreased likelihood of deficiency citations for staffing. Staffing-related deficiencies within nursing homes vary according to various operational, facility, and market characteristics.     

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.
