Social networks and social movements: Multiorganizational fields and recruitment to Mississippi Freedom Summer

This study explores the role of multiorganizational fields in recruitment to social movements. We study applicants to the 1964 Mississippi Freedom Summer project from two sites: the University of California at Berkeley and the University of Wisconsin at Madison. Using network analysis, we develop a model of recruitment that predicts participation on the basis of the structural positions of individuals within the multiorganizational fields, as well as on the basis of individual background factors. We also study the role that the recruitment context plays, by comparing the results at these two universities. Independent of the individual background factors, structural position in the multiorganizational field predicts participation in Freedom Summer at Wisconsin, but not at Berkeley. The effects of individual background factors on participation are also contingent on the recruitment context. We discuss the theoretical implications of our results for the study of the effects of multiorganizational fields and recruitment contexts on participation in social movements.     

Building a new international is necessary and urgent

ABSTRACT

Samir Amin was one of the most creative Marxists, but also an orthodox, as his appeal for a new international proves, consistent with his defense of the socialist revolution against a decaying capitalist system, which threatens with the extinction of human civilization. However, in a contradictory way, if in the past the material conditions did not exist, they exist today, materializing in a distorted manner by capitalism, the organization of a revolutionary international leadership has never been so non-existent. This article begins by demonstrating the systemic conditions that require the proletariat to build a new International, the reasons for the current difficulty in achieving it; and, from the analysis of the most successful experience to date, the Third International, lessons are drawn for a future Fifth International.     

Scheduling internal audit activities: a stochastic combinatorial optimization problem

The problem of finding the optimal timing of audit activities within an organisation has been addressed by many researchers. We propose a stochastic programming formulation with Mixed Integer Linear Programming (MILP) and Constraint Programming (CP) certainty-equivalent models. In experiments neither approach dominates the other. However, the CP approach is orders of magnitude faster for large audit times, and almost as fast as the MILP approach for small audit times. This work generalises a previous approach by relaxing the assumption of instantaneous audits, and by prohibiting concurrent auditing.     

Use of the scale-up methods in injury prevention research: An empirical assessment to the case of choking in children

The scale-up method estimates the size of hard to count subpopulations. This method is based on the idea that the proportion of subjects in a subpopulation E known to each member of the general population T is the same as the proportion of members of E belonging to general population T.     

Sexual Prejudice in Sport Scale: A New Measure

ABSTRACT

This study describes the process of developing and validating the Sexual Prejudice in Sport Scale (SPSS), which is a multidimensional instrument developed to assess attitudes toward lesbians and gay men (LG) in sports. The authors conducted two studies: first, to establish the factor structure of the SPSS on 297 heterosexual athletes; and, second, to test the reliability and validity of the resulting 19-item scale on a sample of 311 heterosexual and 160 LG athletes. Exploratory factor analysis of an initial item pool yielded three factors: open rejection, which assesses the blatant prejudice expressed toward LG people; denial of visibility, which evaluates attitude toward the coming out of LG people; and gendering performance, which corresponds to gender stereotypes about performance/skills of LG people. A confirmatory factor analysis was conducted to assess the stability of the SPSS. The authors documented internal consistency, test-retest stability, and convergent/divergent validity. Implications and directions for future research are discussed.

Prevalence of Problem Gambling Among Adolescents: A Comparison Across Modes of Access,Gambling Activities,and Levels of Severity

The high availability and accessibility of online gambling have recently caused public concern regarding the potential increase of gambling-related problems among young people. Nonetheless, few studies among adults and none among adolescents have explored specific characteristics of gamblers as a function of gambling venues to date. This study sought to analyze the prevalence of gambling among a sample of adolescents in the last year, as well as sociodemographic and gambling-related characteristics as possible predictors of at-risk and problem gambling. The sample comprised 1313 adolescents aged 14–18 years. Participants were asked to respond to several questions regarding their gambling behavior. Chi square and ANOVA tests were performed in order to explore differences between groups, and a set of multinomial regressions established significant severity predictors. The prevalence of at-risk and problem gambling was 4 and 1.2 %, respectively. Regression analyses showed that having a relative with gambling problems predicted at-risk gambling. Both living with only one parent or not living with parents at all, and the prevalence of Electronic Gambling Machines in the last year were associated with problem gambling. Mixed-mode gambling was a predictor of both at-risk and problem gambling. Our findings extend previous research on gambling among adolescents by exploring gambling behavior according to different modes of access. Although the prevalence of exclusive online gambling among the total sample was low, these results support the need to consider specific subgroups of gamblers and their concrete related features when conducting both indicated prevention and treatment protocols for adolescents.     

Traces in the shadow: Occupational outcomes of previously undocumented migrants in Italy

Using a representative sample of currently legal third-country immigrants in Italy, obtained from the Social Condition and Integration of Foreign Citizens survey, this article examines the long-term labour market consequences of previous undocumented spells. First, formerly undocumented immigrants are identified using retrospective information on respondents' legal status. Second, immigrants are classified according to the duration of irregular spells before the achievement of the first residence permit. Third, current labour market outcomes are investigated to account for the endogeneity underlying the previous undocumented history. Results show that even though formerly undocumented immigrants are more likely to participate in the labour market, they are more likely to be employed in underqualified occupations than continuously legal immigrants. The duration of the irregular experience affects occupational qualification negatively, among both men and women. The lack of legal entry channels and policies to plan and regulate migration to Italy may reinforce labour market segmentation, exposing migrants to long-term occupational downgrade.     

Local stationarity in small area estimation models

Small area estimators are often based on linear mixed models under the assumption that relationships among variables are stationary across the area of interest (Fay–Herriot models). This hypothesis is patently violated when the population is divided into heterogeneous latent subgroups. In this paper we propose a local Fay–Herriot model assisted by a Simulated Annealing algorithm to identify the latent subgroups of small areas. The value minimized through the Simulated Annealing algorithm is the sum of the estimated mean squared error (MSE) of the small area estimates. The technique is employed for small area estimates of erosion on agricultural land within the Rathbun Lake Watershed (IA, USA). The results are promising and show that introducing local stationarity in a small area model may lead to useful improvements in the performance of the estimators.
