Non-parametric procedure for knockout tournaments

In a seeded knockout tournament, where teams have some preassigned strength, do we have any assurances that the best team in fact has won? Is there some insight to be gained by considering which teams beat which other teams solely examining the seeds? We pose an answer to these questions by using the difference in the seeds of the two players as the basis for a test statistic. We offer several models for the underlying probability structure to examine the null distribution and power functions and determine these for small tournaments (less than five teams). One structure each for 8 teams and 16 teams is examined, and we conjecture an asymptotic normal distribution for the test statistic.     

Personality traits and knowledge sharing

In this paper, we describe an empirical study that relates three personality traits (agreeableness, conscientiousness and openness) to knowledge sharing. In the existing literature considerable attention has been paid to managerial influences on knowledge sharing, technological support through information and communication systems, or individual characteristics like motivation or the perception of conflict of interest or vulnerability. Instead we concentrate on the role that personal dispositions play in individual’s knowledge sharing behavior. By means of structural equation modeling with PLS, we discover significant correlations between the personality traits and knowledge sharing within teams of an engineering company. Our results clearly contribute to the existing literature, as they offer empirical evidence of the impact of enduring individual characteristics on knowledge sharing.     

Internalizing and externalizing symptoms among unaccompanied refugee and Italian adolescents

This study investigated the prevalence of emotional and behavioral symptoms in unaccompanied refugee adolescents living in Italy; an area which remains under-researched despite the relatively high number of asylum seekers registered in Italy compared to other industrialized countries. The Child Behavior Checklist (CBCL) for 6–18 year-olds was completed by a social worker or parent for each of the 120 participating adolescents; sixty male unaccompanied refugee adolescents and sixty male native Italian adolescents. The paper presents findings that illustrate high levels of emotional and behavioral problems in unaccompanied refugee youth living in Italy. On all components of the CBCL, unaccompanied refugee adolescents were found to present with significantly more problems, as reported by social workers, compared to the Italian group of adolescents. In the light of these results, the importance of interventions and culturally sensitive therapeutic programs for refugee youth is discussed.     

U.S. Population Estimates and Correlates of Sexual Abuse of Community-Dwelling Older Adults

We describe the annual prevalence of sexual abuse among community-dwelling older adults in the United States. We also describe factors associated with experiencing sexual abuse. We used data from 24,343 older adults from the 2005 Behavioral Risk Factor Surveillance System pooled across 18 states. We estimated prevalence of sexual abuse, bivariate distributions, and odds ratio associations across demographic, health, and contextual factors. Our results show that 0.9% of older adults reported experiencing sexual abuse in the previous year. This represents approximately 90,289 community-dwelling older adults. We also report on factors associated with experiencing recent sexual abuse. There was a significant gender by binge drinking interaction, with a stronger association among women. There is a need for health promotion efforts targeted specifically toward older adults, encouraging them to seek services, if possible, after exposure to sexual abuse.     

Occupy's predicament: the moment and the prospects for the movement

Occupy Wall Street has stalled in its attempt to make a transition from a moment to a movement. It had a sizable impact upon the presidential election, driving America's political centre of gravity toward the left, but has been unable or unwilling to evolve beyond its original core into a ‘full‐service movement’ that welcomes contributions from a wide range of activists at varying levels of commitment and skill and plausibly campaigns for substantial reforms. In contrast to earlier American social movements of the twentieth century, the Occupy movement began with a large popular base of support. Propped up by that support, its ‘inner movement’ of core activists with strong anarchist and ‘horizontalist’ beliefs transformed the political environment even as they disdained formal reform demands and conducted decisions in a demanding, fully participatory manner. But the core was deeply suspicious of the ‘cooptive’ and ‘hierarchical’ tendencies of the unions and membership organizations – the ‘outer movement’ – whose supporters made up the bulk of the participants who turned out for Occupy's large demonstrations. The ‘inner movement's’ awkward fit with that ‘outer movement’ blocked transformation into an enduring structure capable of winning substantial reforms over time. When the encampments were dispersed by governmental authorities, the core lost its ability to convert electronic communications into the energy and community that derive from face‐to‐face contact. The outlook for the effectiveness of the movement is decidedly limited unless an alliance of disparate groups develops to press for reforms within the political system.     

Mid- and Late-Life Divorce and Parents’ Perceptions of Emerging Adult Children’s Emotional Reactions

A paucity of research exists pertaining to the experiences of emerging adult children in the context of parental divorce. This study uses Paul R. Amato’s divorce-stress-adjustment framework to organize a set of predictors that potentially influence parents’ perceptions of their emerging adult children’s emotional reactions to a divorce. Data come from a nationally representative AARP study, from which we analyzed a sample of 283 parents who experienced a divorce at age 40 years or older. Results indicate that parental gender, nature of contact with the ex-partner, divorce timing, time spent contemplating divorce, a history of parental divorce, and the reason for divorce influence parents’ perceptions of their emerging adult children’s reaction to the divorce. Implications, limitations, and future direction for research are discussed.     

Listening to Intense Messages: The Role of Arousal and Affect in Message Content Recognition

This study examines the interference effect of high-arousal, affective messages on the recognition of message content from less arousing messages. Subjects were 108 undergraduate students who viewed two political commercials in one of three conditions: Target (low intensity) followed by high-arousal message, target followed by low-arousal message, and target preceded by high-arousal message. The messages used were the political commercials of Michael Bailey concerning family values and abortion.

Results indicated that arousal effects recognition of message content. It appears, however, that high-arousal messages facilitate the recognition of content from a low-arousal message presented either before or after the stimulus.

These results are discussed in terms of current conceptualizations of affect-inducing messages and listening. Areas of further research are also suggested.     

The Predictive Validity of Subjective Mortality Expectations: Evidence From the Health and Retirement Study

Several recent studies suggest that individual subjective survival forecasts are powerful predictors of both mortality and behavior. Using 15 years of longitudinal data from the Health and Retirement Study, I present an alternative view. Across a wide range of ages, predictions of in-sample mortality rates based on subjective forecasts are substantially less accurate than predictions based on population life tables. Subjective forecasts also fail to capture fundamental properties of senescence, including increases in yearly mortality rates with age. To shed light on the mechanisms underlying these biases, I develop and estimate a latent-factor model of how individuals form subjective forecasts. The estimates of this model’s parameters imply that these forecasts incorporate several important sources of measurement error that arguably swamp the useful information they convey.     

Loneliness and Mistreatment of Older Chinese Women: Does Social Support Matter?

The objectives of this study are to: (a) examine the association of loneliness and mistreatment of older Chinese women, and (b) examine the potential modifying effect of social support on these associations. We conducted a cross-sectional study of 141 elderly women presented to an urban medical center. After adjusting for confounders, every 1-point increase in the loneliness score was associated with 44% increased risk for mistreatment. After adding the interaction of social support (social support x loneliness), loneliness was no longer associated with increased risk for mistreatment. Loneliness is a significant risk factor for mistreatment of older Chinese women. Greater social support, particularly perceived social support, may modify loneliness as a risk factor for the mistreatment of older Chinese women.     

Former Spouse Ties and Postdivorce Relationship Quality: Relationship Effort as a Mediator

ABSTRACT

One potential problem area in remarriages is problems with or ties to an ex-spouse. This study focuses on identifying factors central to the relationship dynamics such as relationship satisfaction and stability. Additional emphasis is placed on specific and targeted work in a relationship with the goal of improving it, and its potential mediating effect on any negative relationship between ex-spouse ties and low relationship quality. Using secondary data from the RELATionship Evaluation Survey (RELATE), a sample of 1,546 individuals in postdivorce romantic relationships was examined. The results indicate that unresolved issues and negative interactions with an ex-spouse are negatively associated with relationship quality, but effort to mediate this negative association shows promise. Practice recommendations include exploring how family service agencies and clinicians can better serve couples in postdivorce relationships. Further, a focus on the repartnered family system and a recognition of its difference from other family system types (i.e., first marriage) are important for agencies, clinicians, and researchers interested in providing services to stepfamilies and family life after divorce.
