Risk Factors of Sexual Harassment by Peers: A Longitudinal Investigation of African American and European American Adolescents

The present research explores risk factors for, and longitudinal associations of, sexual harassment by peers during adolescence. Eight‐hundred and seventy‐two African American and European American adolescents (65.4% African American, 51.1% females) were assessed during the summer after the eighth grade (mean age=14.2 years) and then again in the 11th grade (mean age=17.1 years). At the first assessment, adolescents were asked about their experiences with sexual harassment, their psychological reactions to sexual harassment, and also about their peer relationships, perceived pubertal timing, problem behavior, and mental health. At the second assessment, adolescents reported on their problem behavior and mental health. In general, youth who associated with peers who were involved in problem behavior were at risk for victimization. Among females, those who perceived themselves to be experiencing early pubertal development were also at risk. Additionally, for some adolescents, sexual harassment predicted later adjustment difficulties.     

Practice and Research in Career Counseling and Development—2002

The authors present a review of the 2002 career development literature. The literature review is divided into the following areas: career theory, career assessment, career counseling interventions and practice, career counseling training and professional issues, and international issues in career counseling. The authors discuss the implications of the findings in this literature for career counseling practice.     

Perceived Racial Discrimination as a Predictor of Health Behaviors: the Moderating Role of Gender

Perceived racial discrimination (PRD) has been implicated in undermining the mental and physical health of racial/ethnic minorities (e.g., Williams et al. in Am J Public Health 93:200–208, 2003; Wong et al. in J Pers 71:1197–1232, 2003). Researchers have begun to explore the indirect role of health behaviors as one factor in helping to explain this relationship. The goal of the present study was to examine the relationship between PRD and a wide range of health behaviors using a prospective, longitudinal design and to explore the role of gender in moderating these relationships. Using data from the Maryland Adolescent Development in Context Study, we examined the relationship between adolescent PRD (accumulated across ages 14–21) and health behaviors (i.e., diet, substance use, exercise) at age 30 in a sample of middle-class black men and women. Using structural equation modeling, results revealed that more cumulative PRD during adolescence was associated with less healthy eating, more substance use (among men), and more exercise (among women) in young adulthood. Implications of these findings for understanding the role of health behaviors in explaining the link between PRD and health outcomes are considered.     

Threats and Supports to Female Students’ Math Beliefs and Achievement

This study examines how student perceptions of teacher practices contribute to female high school students’ math beliefs and achievement. Guided by the expectancy–value framework, we hypothesized that students’ motivation beliefs and achievement outcomes in mathematics are fostered by teachers’ emphasis on the relevance of mathematics and constrained by gender‐based differential treatment. To examine these questions, structural equation modeling was applied to a longitudinal panel of 518 female students from the Maryland Adolescent Development in Context Study. While controlling for prior achievement and race, gendered differential treatment was negatively associated with math beliefs and achievement, whereas relevant math instruction was positively associated with these outcomes. These findings suggest inroads that may foster positive math motivational beliefs and achievement among young women.     

Facilitating labour migration from Latvia: strategies of various categories of intermediaries

ABSTRACT

Within the broad category of migration industries, we focus on intermediaries between employers in Norway requiring migrant labour, and suppliers of Latvian workers willing to migrate. Mediation of labour power is a regulated domain in both countries, but regulations may change: regulations in Latvia have become more lenient, whereas in Norway, they have become stricter in response to increased migration. Intermediaries must be responsive to fluctuations in labour supply and demand, as well as to changing regulations. Today, destination countries are experiencing an overabundance of available migrant labour. This buyer’s labour market represents a challenge for intermediaries, spurring adjustments and side-stepping of regulations. Formal temp agencies are supplemented by informal ones, challenging the conceptualisation of intermediaries. Also work migrants may become agents, shaping new forms of intermediation and expanding the concept of ‘migration industry’ to encompass facilitation of labour migration through social networks. In this article, we construct typologies inductively, establishing categories meaningful in the complex context of labour migration from Latvia to Norway. We distinguish between mediation through formal versus informal agencies, establish characteristics of agencies versus individual social network-based mediation and discuss mediation through the posting of workers by companies.     

Monitoring proteins in intact cells

In the past decade, tremendous progress has been made in understanding the molecular mechanisms that underlie many neurodegenerative disorders, and common aspects of the pathological processes that lead to neuronal cell death have emerged. Nearly all of these advances have come from genetic, molecular, and biochemical studies that point to alterations in protein folding or protein-protein interactions as the fundamental mechanism behind these disorders. New microscopy/imaging technologies for detecting protein-protein interactions are now poised to contribute to progress in this field. Here we describe a novel technique based on fluorescence resonance energy transfer, called fluorescence lifetime imaging microscopy (FLIM), which allows monitoring of protein conformation and protein-protein interactions in intact cells. For example, using FLIM, we have studied the interaction of two proteins related to Alzheimer's disease: amyloid precursor protein (APP) and presenilin (PS-1). By measuring the lifetime of a donor fluorophore linked to PS-1, we show, with high subcellular resolution, localization of the PS-1-APP interaction within neurons. This approach may have widespread applicability in studies of neurodegenerative disease mechanisms.     

Prevalence of Problem and Pathological Gambling in Parkinson’s Disease

Pathological gambling (PG) has been identified in patients with Parkinson’s disease (PD) treated with dopamine agonists suggesting that dysregulation of brain dopaminergic activity may contribute to the development of gambling problems. The current study was undertaken to further establish the prevalence of problem and PG in patients with PD, identify any clinical correlates, and determine if psychiatric or substance use co-morbidity contributes to the increased prevalence of problem and PG. A cross-sectional survey of 140 serially recruited moderate to severe PD patients was undertaken utilizing the Canadian Problem Gambling Index, Alcohol Use Disorders Identification Test, Drug Abuse Screening Test, Beck Depression Inventory, Beck Anxiety Inventory, and Mini-Mental State Exam augmented by chart review, completed over an 8 month period. The 12 month prevalence of problem and PG in PD was 9.3% compared to 1.6% in the general population within a comparably aged sample. The increased prevalence of problem and PG in the PD group was related to dopamine agonist use and younger age, but not co-morbidity. Most subjects with problem and PG reported their gambling increased after being diagnosed with PD and starting treatment. The results suggest that brain dopaminergic activity is involved in the underlying neurobiology of problem and PG.     

Governmental anti-pandemic policies,vaccination, population mobility,Twitter narratives,and the spread of COVID-19: Evidence from the European Union countries

We provide large-scale empirical evidence on the effects of multiple governmental regulatory and health policies, vaccination, population mobility, and COVID-19-related Twitter narratives on the spread of a new coronavirus infection. Using multiple-level fixed effects panel data model with weekly data for 27 European Union countries in the period of March 2020–June 2021, we show that governmental response policies were effective both in reducing the number of COVID-19 infection cases and deaths from it, particularly, in the countries with higher level of rule of law. Vaccination expectedly helped to decrease the number of virus cases. Reductions in population mobility in public places and workplaces were also powerful in fighting the pandemic. Next, we identify four core pandemic-related Twitter narratives: governmental response policies, people's sad feelings during the pandemic, vaccination, and pandemic-related international politics. We find that sad feelings’ narrative helped to combat the virus spread in EU countries. Our findings also reveal that while in countries with high rule of law international politics’ narrative helped to reduce the virus spread, in countries with low rule of law the effect was strictly the opposite. The latter finding suggests that trust in politicians played an important role in confronting the pandemic.
