Associations between hormonal and physical status and girls' depressive affect, aggressive affect, and delinquent behavior were studied over the course of one year. Seventy-two White girls, aged 10–14 at initial data collection, were seen twice. Endocrinological status (estradiol, luteinizing hormone [LH], folicle stimulating hormone [FSH], testosterone, and dehydroepiandosterone sulfate [DHEAS] at Time 1, physical development (menarche, secondary sexual characteristics) and maturational timing at Times 1 and 2 were used to predict self- and maternal reports of depressive affect, and self-reports of aggressive affect and delinquent behavior at Time 2. It was posited that initial endocrinological status, as represented by hormonal categories derived by Warren and Brooks-Gunn [(1989) Mood and Behavior at Adolescence: Evidence for Hormonal Factors, Journal of Clinical Endocrinology and Metabolism, Vol. 69, pp. 77–83] and reflecting estradiol, LH, and FSH levels, would be associated with affective expression and delinquent behavior one year later. DHEAS, however, was not expected to be associated with affective expression a year later as it is thought to be more indicative of adrenal changes that are in part environmentally mediated. Initial affective expression was hypothesized to account for more of the variation than prior hormonal status. Hormonal categories predicted depressive and aggressive affect a year later, while DHEAS, physical status, and maturational timing did not. Initial hormonal categories were associated with subsequent reports of delinquent behavior, although not after physical status or prior reports of delinquency were entered into the regression. Initial reports of affective expression accounted for a far greater proportion of the variance in aggressive affect and delinquent behavior than did hormonal or physical status.Received Ph.D. from Institute of Child Development, University of Minnesota.

Recent field experiments have demonstrated the powerful effect of social pressure messages on voter turnout. This research
note considers the question of whether these interventions’ effects persist over a series of subsequent elections. Tracking
more than one million voters from six experimental studies, we find strong and statistically significant enduring effects
one and sometimes two years after the initial communication. 相似文献

Nearly all research on the political impact of Americans’ religious and secular orientations assumes that such orientations are exogenous to politics. Using multiwave panel and experimental data, we find that religious and secular orientations are endogenous to political orientations. In other words, religion and secularism are a consequence as well as a cause of politics. In showing this, we make three major contributions. First, we conceptualize and measure secular orientations in a new way—not just as the absence of religion, but also as an affirmative secular identity and positive commitment to secular principles. Second, our panel and experimental data allow for the most definitive test to date of whether political orientations exert a causal effect on religious and secular orientations. Third, we isolate the conditions under which politics affects religious–secular perspectives, thus identifying the mechanism that underlies political orientations. 相似文献

As the twenty-first century appears to be entering a more intensified globalised nuclear age, nations and academics alike consistently criticise the frameworks and foundational agencies created to ensure non-proliferation, security, and multi-lateral negotiations. Notwithstanding the significant reductions in nuclear arsenals made over the last several decades, thanks to the Nuclear Non-Proliferation Treaty and the numerous nuclear agencies and watchdogs, it is evident that the risks emanating from nuclear weapons and their associated materials have continually expanded. By ensuring that the global community has protections and safeguards in place to promote international dialogue and nuclear non-proliferation—including the Cooperative Nuclear Threat Reduction Program, International Atomic Energy Agency, Global Threat Reduction Initiative, as well as nuclear free zones and review processes—the nuclear non-proliferation regime can arguably ensure that the devastating threat to humankind is reduced. However, as countries scramble to once again refine and modernise their nuclear stockpiles, the necessity to review, re-shape, and re-think these foundational safeguards is more vital than ever. 相似文献

What do nuclear weapons mean for the stability of the military balance? Mutually assured destruction (MAD) describes a stalemated balance of power where nuclear adversaries possess survivable retaliatory capabilities that ensure neither side can escape devastation in an all-out nuclear war. Moreover, the strong form of this empirical claim, which one might term “deep MAD,” is that mutual vulnerability is an inalterable and unchangeable condition. Drawing from recently declassified primary sources, we test several of deep MAD's premises and predictions on one of its foundational cases: Soviet nuclear policy during the second half of the Cold War. We find that Soviet leaders remained seriously concerned about the nuclear balance even in an allegedly deep-MAD environment where warheads numbered in the tens of thousands. Indeed, Soviet leaders were uncertain that they could indefinitely maintain a secure second strike despite strenuous efforts. The reason for these discrepancies, we argue, is that the nuclear balance is actually more malleable than commonly admitted. The possibility that MAD might one day be escaped meant that US attempts to manipulate the nuclear balance during the latter part of the Cold War could carry political weight, even while MAD was still possible. 相似文献

The U.S. incarceration rate rose dramatically over the past 45 years, increasing the number of marriages and cohabiting unions disrupted by a jail or prison stay. But as some have pointed out, not all unions dissolve as a result of incarceration, and there seems to be racial–ethnic variation in this tendency, with Blacks displaying higher rates of dissolution than Whites and Hispanics. Yet it is unclear what explains racial–ethnic differences in union dissolution among the incarcerated. Drawing on the National Longitudinal Survey of Youth 1997 (NLSY97), we examine why racial–ethnic differences in union dissolution exist among a sample of individuals who had a marital or a cohabiting union interrupted by an incarceration spell. In doing so, we draw on social exchange theory and structural and cultural theories to suggest that racial–ethnic disparities in union dissolution are explained by differential exposure to protective relationship characteristics. The results of Cox hazard models reveal that Blacks have significantly higher hazards of union dissolution than do Whites and Hispanics. These results also indicate that being married, having a child together, having full-time employment, a longer union duration, and a shorter incarceration spell may protect against dissolution and that these factors account, in part, for the greater risk of dissolution among Blacks relative to Whites and Hispanics. 相似文献

Recently, the timing-of-events model typically used for exploring adult development has been proposed for studying early adolescence and the pubertal processes occurring then. As a consequence, new interest has been generated about the psychological effects of being early, on time, or late in sexual maturation during early adolescence. A major issue has to do with the choice of maturational events to study, since puberty is a process involving numerous events, all of which have a different developmental course. This paper reviews some of the maturational events that are applicable in studying psychological effects of pubertal status and timing. Nine changes are reviewed (bone, height, weight, body fat, breast, body hair, penile, testicular, and menarcheal changes) in terms of measurement techniques, psychometric properties, and intercorrelations with other pubertal events. In addition, the usefulness of each measure for psychological research on maturational timing and status is discussed. Finally, how pubertal measures may be incorporated into a developmental perspective is considered, especially with regard to rate, duration, and asynchrony of pubertal changes.Research Interests: Girl's psychological adaptation to pubertal change, biosocial aspects of female reproductive events, development of biological and socially at risk children and adolescents.Research Interests: Reproductive endocrinology, anorexia nervosa, neuroendocrinology, adolescence. 相似文献

For almost two decades restorative justice practices have demonstrated positive impacts on crime victim satisfaction when compared to court and other adversarial processes. Although restorative justice practice has by no means addressed the myriad needs of the majority of crime victims, researchers and policy makers have puzzled about how to interpret these generally positive findings. We suggest that remaining difficulties in interpretation and application of findings are due largely to (1) the lack of clear standards for gauging the integrity, or “restorativeness,” of interventions and (2) the failure to articulate logical mechanisms (i.e., intervention theories) that connect practices to immediate and intermediate outcomes, and these outcomes to long term changes in the well-being of victims, offenders, and communities. This article focuses primarily on the first problem, defining the “independent variable” in restorative practices aimed at having an impact on crime victims. Using qualitative data from a national case study, a principle-based approach to evaluation with implications for intervention theory and both input and outcome measures in future research is proposed and briefly illustrated. 相似文献
