China and the competition for oil and gas in Asia

While its economic dynamism stimulates continued growth in Asia, China's increasing demand for energy is creating intense competition, particularly with Japan, over international sources of supply. Domestic fields have generally been disappointing, as have efforts to pipe gas from Central Asia and Russia to the east coast. Consequently, China is not only paying greater attention to potential petroleum resources in the East and South China Seas, but also considering the vulnerability of its sea-lanes to the Middle East and beyond. Its need to diversify has promoted closer relations with Central Asia, the Middle East, and the oil producing countries of Africa and Latin America, but the jury is out on whether China's concerns for secure energy supply will lead to international cooperation against terrorism or fuel the already heated competition for oil and gas. As China continues to assure its future energy security in Asia and many areas of the world, sustained bilateral and multilateral diplomacy to reconcile disputes and avoid conflict will become more important than ever.     

Stammwähler und die opportunistische Wahl parteipolitischer Programme

This article explains political radicalism by the number of voters who are biased towards a party. With little voters biased in favor of a party, this party has to rely more heavily on its programmatic distance to other parties. Because large parties – i.e.: parties with a high number of biased voters – gain votes when they move to the center of the political spectrum, parties with a lower number of voters that are biased in their favor are forced to the edges of the policy space. We draw on a computational model of political competition between four parties in a two‐dimensional policy space to investigate this relationship. We use panel corrected OLS estimates to analyze the data generated by the computer simulation. Our results substantiate the hypothesis of a negative relationship between the number of biased voters and the inclination of a party to adopt a more extreme policy stance.     

Finanzpolitik als Nachahmungswettbewerb: Empirische Ergebnisse zu Budgetinterdependenzen unter den Schweizer Kantonen

This article examines whether spending decisions in Swiss cantons are interdependent, that is, whether the spending decisions of a canton are influenced by those of other cantons. Theoretically, fiscal policy imitation among cantons can be interpreted as a process of policy and innovation diffusion, as a result of tax competition or as a consequence of federalism as a policy laboratory. The panel analysis presented in this article provides evidence of the existence of budget spillovers among neighbouring cantons. Cantonal governments do not take spending decisions in isolation, but by systematically comparing the fiscal policies in neighbouring cantons.

Gender and Gender-Role Orientation Differences on Adolescents' Coping with Peer Stressors

Gender and gender-role orientation differences were explored on adolescents' coping with peer stressors. Eighth-grade and ninth-grade public junior high school students (N = 285) completed the COPE, reporting the strategies they recently used to deal with a stressful peer-related situation. Measures of gender-role orientation (Bem Sex-Role Inventory) and demographic information also were obtained. Factor analysis of the COPE revealed 4 distinct coping factors: active, avoidant, acceptance, and emotion-focused. The most frequently reported stressful event was arguments/fights with same-sex friends. Girls reported more arguments/fights with opposite-sex friends. Boys reported more physical fights and threats. Students' ratings of how much the situation mattered were used as a covariate in a MANCOVA to compare coping by gender and gender-role orientation, to control for perceived stressfulness of situations. Significant gender-role orientation differences were found for active, acceptance, and emotion-focused coping.     

Cultural Equivalence and Cultural Variance in Longitudinal Associations of Young Adolescent Self-Definition and Interpersonal Relatedness to Psychological and School Adjustment

Ethnic group differences in the contributions of self-definition (self-worth and efficacy) and interpersonal relatedness with parents and peers to changes in psychological and school adjustment were examined among 448 White, Black, and Latino girls and boys (11–14 years of age). Self-report questionnaires and school records were evaluated for socioeconomic and ethnic group differences in patterns of change over 1 year. Overall similarity in changes over time across ethnic groups was found for relatedness, self-definition, and psychological adjustment, although Black and Latino youth reported more overall adjustment difficulties, Black youth reported less positive relationships with parents, and lower SES youth reported less positive peer relationships than others. Ethnic group differences in changes to school adjustment, even after controlling SES, suggested a cultural variation in which often cited declines in school adjustment during middle school characterize White adolescents to a greater degree than Black or Latino adolescents. Ethnicity moderated associations of relatedness and self-definition with psychological and school adjustment such that Black and Latino youth appeared particularly vulnerable to experiences that threaten closeness and trust in relationships. Results pointed to potentially important situational and cultural differences in maladaptive and adaptive developmental processes across ethnicity.     

School Belonging,Self-Esteem,and Depressive Symptoms in Adolescents: An Examination of Sex,Sexual Attraction Status,and Urbanicity

Using data from Wave II of the National Longitudinal Study of Adolescent Health (Add Health; Bearman, P. S., Jones, J., and Udry, J. R. http://www.cpc.unc.edu/projects/addhealth/design.html, 1997), we conducted multivariate analyses to examine three indicators of psychosocial adjustment (school belonging, self-esteem, depressive symptoms) and their associations with sexual attraction status, sex, and urbanicity. In general, sexual minority adolescents reported lower psychological adjustment than adolescents endorsing other-sex attractions only, with sexual minority females at particular risk. Further, differential patterns of risk for sexual minority youth emerged across rural, urban, and suburban communities. We conclude by discussing implications of these findings for addressing the psychosocial needs of sexual minority adolescents.     

Identity Style,Parental Authority,and Identity Commitment

The role that parental authority patterns and social-cognitive identity styles may play in establishing identity commitments was investigated. The results indicated that family authority and identity style variables combined accounted for 50% of the variation in strength of identity commitment. As hypothesized, the relationship between parental authority and identity commitment was mediated by identity style. The findings are consistent with the view that family authority patterns may contribute to the way in which late adolescents negotiate the task of constructing a sense of identity. Alternative explanations of the findings are considered.     

Efficacy, Self-Derogation, and Alcohol Use Among Inner-City Adolescents: Gender Matters

Prior studies have found inconsistent relationships between measures of self-concept and adolescent alcohol use. The current study explored whether the link between various measures of self-concept and alcohol use depends on gender. In addition, earlier work suggested a focus on negative self-esteem (i.e., self-derogation) might be more useful in predicting alcohol use. Students (N = 1459) attending 22 middle and junior high schools in New York City completed surveys that included measures of efficacy, self-derogation, and alcohol use. Participants completed surveys at baseline, 1-year follow-up, and 2-year follow-up. Data collectors administered the questionnaire following a standardized protocol during a regular 40-min-class period. On the basis of a longitudinal structural equation model, lower efficacy was related to greater self-derogation a year later across gender. Increased self-derogation predicted higher alcohol use for girls but not boys. These findings are congruent with a literature highlighting the importance of negative thoughts about the self in drinking behavior for women but not men. The results suggest that the alcohol prevention approaches should include material to enhance girls' self-esteem.     

Who's the Boss? Patterns of Perceived Control in Adolescents' Friendships

This study examined the nature and correlates of different patterns of perceived control in adolescents' relationships with their best friends. Participants included firstborn adolescents (M = 14.94 years), their younger siblings (M = 12.44 years) and both their mothers and fathers in 163 families as well as a best friend of each adolescent (M = 15 years). Data were collected from family members during home visits regarding adolescents' family relationships, friendships, and psychosocial adjustment; time use data were gathered during a series of 7 nightly phone interviews. Information was obtained from best friends during a brief phone interview. We developed a typology of 3 different patterns of perceived friendship control based on the combination of adolescents' and their best friends' ratings of relational control. Patterns of control in adolescents' friendships were associated with the distribution of control in both parents' marriages and adolescents' sibling relationships. Further analyses, designed to test developmental predictions, revealed connections between friendship control and other qualities of adolescents' friendships (i.e., intimacy, conflict, perspective-taking).
