Enforcing alcohol policies on college campuses: reports from college enforcement officials

We assessed alcohol enforcement practices at 343 U.S. colleges via surveys of directors of campus law enforcement. We measured types and frequency of enforcement and barriers to enforcement. We found that 61% of colleges indicated nearly always proactively enforcing alcohol policies, with most frequent enforcement at intercollegiate sporting events and least frequent enforcement at fraternity/sorority events. Approximately half of the enforcement departments work closely with their local law enforcement agency but respondents indicated a greater need for cooperation with local law enforcement. Half of the respondents reported no barriers to alcohol enforcement on campus. Large colleges and public colleges tended to report greater enforcement levels. While many campuses report proactive alcohol enforcement, several areas of improvement in alcohol enforcement at colleges are indicated.     

Team factors that predict to sustainability indicators for community-based prevention teams

Because they often set out with a guarantee of only short-term funding, many community partnerships will face a threat to their sustainability almost as soon as the first money runs out. Research into the factors that enable some coalitions and partnerships to meet the challenge when others fail is limited. This study begins to fill this gap in our understanding by examining influences on the process of sustainability planning in the context of a collaborative partnership focused on youth development. We report on a longitudinal examination of the quality of planning and attitudes underpinning the sustainability of PROSPER community prevention teams whose members implement evidence-based programs designed to support positive youth development and reduce early substance use and other problem behaviors. The current research concentrates on a particular dimension of partnership effectiveness to establish whether perceptions about team functioning in play at 6 and 18 months predict the quality of sustainability planning at 36 and 48 months. How well teams functioned in the early stages was found to be strongly related to the quality of their later preparations for sustainability. Recruitment and integration of new team members, and the encouragement they subsequently received were also found to be key factors. The results strengthen the argument for providing technical assistance to meet the needs of those who promote prevention partnerships, and they provide longitudinal empirical data to support the hypotheses of other researchers who have similarly found a correlation between effective sustainability and early planning and support.     

Evaluation of free to grow: head start partnerships to promote substance-free communities

Free to Grow: Head Start Partnerships to Promote Substance-free Communities (FTG) was a national initiative in which local Head Start (HS) agencies, in partnership with other community organizations, implemented a mix of evidence-based family-strengthening and community-strengthening strategies. The evaluation of FTG used a quasi-experimental design to compare 14 communities that participated in the FTG intervention with 14 matched comparison communities. Telephone surveys were conducted with two cohorts of the primary caregivers of children in HS at baseline and then annually for 2 years. The survey was also administered to repeated cross-sectional samples of primary caregivers of young children who were not enrolled in HS. No consistent evidence was found in changes in family functioning or neighborhood conditions when the 14 FTG sites were compared to 14 matched sites. However, caregivers of young children who were not in HS in three high-implementing FTG sites showed evidence of improvements in neighborhood organization, neighborhood norms against substance abuse, and child disciplinary practices. Results provide highly limited support for the concept that family and neighborhood conditions that are likely to affect child development and well-being can be changed through organized efforts implemented by local HS programs.

GENDER DIFFERENCES IN WORK SATISFACTION

This paper explores differences between men and women in levels of work satisfaction, employing data from the Australian component of the International Project on Class Structure and Class Consciousness. While women tend to be concentrated in low-status, low-paid positions, that is the secondary labour market, the data suggest that, in general, they are more satisfied with paid employment than men. Employment constraints are found to be a key factor in the observed differences in levels of work satisfaction. For both groups, however, it is clear that work satisfaction derives primarily from work-related factors.     

Economic concentration and corporate political behavior: A cross-industry comparison

Several political sociologists have argued that the trend toward economic concentration in major industries in advanced capitalist societies has led to a growth in corporate political power. Most of these arguments are based on the notion that economic concentration facilitates the mobilization of industries as cohesive politica actors. This paper presents an empirical examination of this argument. The similarity of campaign contributions in the 1980 Congressional elections by the four largest members of 25 industries is employed as the dependent variable. Concentration ratios within the industries, sizes and geographical proximities of the firms, and measures of within-industry economic and social integration are employed as independent and intervening variables. Employing a spatial autocorrelation model to correct for nonindependence among observations, we find that although concentration and similarity of political behavior are positively associated in a bivariate correlation, the relation disappears when controls are introduced. Common stock ownership by the same institutions and indirect director interlocks through financial institutions are significant predictors of behavioral similarity.     

On maximum likelihood estimation of the semi-parametric Cox model with time-varying covariates

Including time-varying covariates is a popular extension to the Cox model and a suitable approach for dealing with non-proportional hazards. However, partial likelihood (PL) estimation of this model has three shortcomings: (i) estimated regression coefficients can be less accurate in small samples with heavy censoring; (ii) the baseline hazard is not directly estimated and (iii) a covariance matrix for both the regression coefficients and the baseline hazard is not easily produced.We address these by developing a maximum likelihood (ML) approach to jointly estimate regression coefficients and baseline hazard using a constrained optimisation ensuring the latter''s non-negativity. We demonstrate asymptotic properties of these estimates and show via simulation their increased accuracy compared to PL estimates in small samples and show our method produces smoother baseline hazard estimates than the Breslow estimator.Finally, we apply our method to two examples, including an important real-world financial example to estimate time to default for retail home loans. We demonstrate using our ML estimate for the baseline hazard can give much clearer corroboratory evidence of the ‘humped hazard’, whereby the risk of loan default rises to a peak and then later falls.     

How Much More XXX is Generation X Consuming? Evidence of Changing Attitudes and Behaviors Related to Pornography Since 1973

We use data from the General Social Survey (GSS) over a 40-year period (1973–2012) to evaluate changes in attitudes about pornography and pornography consumption among American young adults. One of the major challenges in making comparisons across birth generations is separating the effect of birth cohort from age and period effects. We use an intrinsic estimator to separately identify the effects of age, birth cohort, and time period using 40 years of repeated cross-section data. We find that, relative to the general population, young people's beliefs about whether pornography should be illegal have stayed relatively constant over this 40-year period and, if anything, have slightly increased. We also find that pornography consumption has been increasing across birth generations, though this increase has been smaller than would be inferred based on differences across generations at a single point in time, due to a strong age component in consumption patterns.     

Poverty,Place, and Coal Employment across Appalachia and the United States in a New Economic Era

The impacts of employment in the coal industry remain controversial. Few studies have investigated these impacts over the decade of the great recession and in light of the nation's changing energy economy. We bring together two long‐standing rural sociological traditions to address debates framed at the national level and for Appalachian communities facing the throes of transition from the coal industry. Building from rural sociology's “poverty and place” tradition and from natural resources sociology, we examine the relationship between coal employment and communities’ economic well‐being as indicated by poverty, household income, and unemployment. The study spans U.S. and Appalachian counties from 1990 to 2010. U.S. counties with greater coal employment in 1990 had lower income and higher poverty in 2000. Overall, however, coal employment's effect is mixed in the 1990–2000 decade. By contrast, for the recent 2000–2010 decade, coal employment is positively associated with indicators of well‐being. In Appalachia, fewer employment alternatives outside mining are related to higher well‐being. Our findings extend the poverty and place literature and the natural resources literature and underscore why a just transition away from coal should focus on moving communities toward sectors offering better future livelihoods.
