Increasing diplomatic tension between China and the United States has led to concerns about military conflict, possibly including rapid nuclear escalation. Scholars have spent less time considering the opposite scenario: protracted conventional war. This analysis explains why a combination of politics, geography, and technology may conspire to produce such a war, despite the fact that both sides are planning for a short, high-intensity fight. It shows how the Peloponnesian War, an ancient conflict fought with ancient weapons, nonetheless provides a warning of what might happen in the present. It also describes a grim trade off that American policy-makers will face in the event of war. Washington can take steps to reduce the chance of nuclear escalation, but in so doing will make a long war more likely. The conclusion describes the diplomatic challenge of war termination in a protracted conflict where neither side can compel the other to back down. 相似文献

Out-of-school time programs focused on science, technology, engineering and mathematics (STEM) have proliferated recently because they are seen as having potential to appeal to youth and enhance STEM interest. Although such programs are not mandatory, youth are not always involved in making the choice about their participation and it is unclear whether youth’s involvement in the choice to attend impacts their program experiences. Using data collected from experience sampling, traditional surveys, and video recordings, we explore relationships among youth’s choice to attend out-of-school time programs (measured through a pre-survey) and their experience of affect (i.e., youth experience sampling ratings of happiness and excitement) and engagement (i.e., youth experience sampling ratings of concentration and effort) during program activities. Data were collected from a racially and ethnically diverse sample of 10–16 year old youth (n?=?203; 50% female) enrolled in nine different summer STEM programs targeting underserved youth. Multilevel analysis indicated that choice and affect are independently and positively associated with momentary engagement. Though choice to enroll was a significant predictor of momentary engagement, positive affective experiences during the program may compensate for any decrements to engagement associated with lack of choice. Together, these findings have implications for researchers, parents, and educators and administrators of out-of-school time programming. 相似文献

Trait impulsivity is a risk factor for rule breaking and aggressive (externalizing) behaviors among nonclinical youth. Buffers of trait-based risk are of practical interest to preventing externalizing behaviors. One such buffer may be the capacity and efforts of a child to self-regulate their physiology. Youth who possess baseline physiological self-regulatory capacities are more likely to maintain adaptive engagement with their environment and may be less prone to impulsively rule break or be aggressive. Similarly, youth who are able to use self-regulatory skills to calm their physiology in times of stress may be less likely to externalize distress. This study examined self-regulatory capacity and efforts as a moderator of the relationship between trait impulsivity and externalizing behaviors, cross-sectionally and prospectively. We hypothesized that the effect of trait impulsivity on externalizing behaviors would depend on the presence of baseline self-regulatory capacity and/or self-regulatory efforts during stress. Participants were 134 nonclinical adolescents (Mage?=?12.59, SD?=?1.20 51.9% female, 71% Caucasian). Trait impulsivity was measured using a parental report questionnaire. Physiological self-regulatory capacity and efforts were measured through collection of electrocardiogram data during a resting baseline and a stressful, unsolvable anagram task, respectively. Physiological self-regulation was quantified by calculating respiratory sinus arrhythmia scores across baseline and stress tasks. Respiratory sinus arrhythmia is the change in heart rate across the breathing cycle, and is hypothesized to index physiological self-regulation capacity and efforts under specific conditions. The results indicated that physiological self-regulation capacity, but not efforts, moderated the effect of trait impulsivity on externalizing behaviors prospectively. Stronger physiological self-regulatory capacity buffered the effect of greater trait impulsivity. Implications of these findings among typically developing youth are discussed. 相似文献

This paper tests theoretical arguments that suggest court actors hold gendered views of sex offenders that result in a gender gap in sex offender punishment, where women who commit sexual offenses are treated more leniently than their male counterparts. We test this argument with precision matching analyses using 15 years of data on all felony sex offenders sentenced in a single state. Results indicate that gender disparities in sex offender sentencing exist and are pervasive across sex offense types. Specifically, male sex offenders are more likely to be sentenced to prison, and given longer terms, than female sex offenders. Findings are similar across sex offense severity and whether the offense involved a minor victim. These findings suggest that female sex offenders are treated more leniently than their matched male counterparts, even in instances of more serious sex offenses and those involving minor victims. Findings support theoretical arguments that contend that court decision-making is influenced by legally-irrelevant characteristics and raise questions about the source of gendered views of sex offenders and their effects on punishment approaches. Findings also raise questions about the virtue of get-tough sentencing policies that provide leeway for such dramatic variation across different groups of people. 相似文献

This essay returns to key debates in performance theory regarding the relationship between performance and reproduction, offering a Marxian inflected theory of performance’s mode of reproduction. It suggests that both performance theory and Marxist theory appropriate the mother function in describing performance’s mode of reproduction and the reproduction of capital, while displacing the mother in the process. Through a reading of the work of contemporary artist Danh Võ, the essay explores how performance’s mode of reproduction can affect the reproduction and sustenance of minoritarian life against historical, social, and economic forces of elision, erasure, and annihilation. 相似文献

How does state repression affect the incidence and impact of terrorism? This study conducts a process tracing analysis of the ongoing contention between the Uyghur separatist movement and the Chinese state to provide a plausible explanation for the present lack of consensus on this question. Relying on insights from collective action theory, it argues that although repression was initially successful in curtailing the opportunistic use of terrorism, novel political opportunity allowed some separatists to adopt innovations, such as suicide bombing, to circumvent repression. Repression has since proved ineffective in quelling terrorism, and will likely remain incapable of forestalling future terrorist innovations. 相似文献
