Data collection using the life event calendar method is growing, but reliability is not well established. We examine test–retest
reliability of monthly self-reports of criminal behavior collected using a life event calendar from a random sample of minimum
and medium security prisoners. Tabular analysis indicates substantial agreement between self-reports of drug dealing, property,
and violent crime during a baseline interview (test) and a follow-up (retest) approximately 3 weeks later. Hierarchical analysis
reveals that criminal activity reported during the initial test is strongly associated with responses given in the retest,
and that the relationship varies only by the lag in days between the initial interview and the retest. Analysis of validity
reveals that self-reported incarceration history is strongly predictive of official incarceration history although we were
unable to address whether subjects could correctly identify the months they were incarcerated. African Americans and older
subjects provide more valid responses but in practical terms the differences in validity are not large. 相似文献

Legal clarity is important to understand and measure because of its connection to the rule of law. We provide the first systematic examination of the clarity of Supreme Court opinions and discover five important results. First, certain justices systematically craft clearer opinions than others. Justices Scalia and Breyer write the clearest opinions, while Justice Ginsburg consistently writes the most complex opinions. Second, ideology does not predict clarity in majority or concurring opinions. Third, all justices write clearer dissents than majority opinions, while minimum winning coalitions produce the clearest majority opinions. Fourth, justices across the board write clearer opinions in criminal procedure cases than in any other issue area. Finally, opinions that formally alter Court precedent render less clear law, potentially leading to a cycle of legal ambiguity. 相似文献

The inquest into the death of Kerrie Wooltorton in Norfolk, England, ignited extensive public debate on the scope of the common law right to refuse medical treatment where a patient is distressed, depressed or actively suicidal. In Australia, a patient's wishes need not be honoured if the patient is not legally competent, if he or she falls within the ambit of the compulsory treatment provisions in the mental health legislation, and possibly also if there is a recognised public interest in preventing suicide which is sufficient to override the patient's choice. This article argues that decisions about whether to give medical treatment despite an apparent refusal should be based solely on a determination of the patient's competence to make their own choice. However, the test for legal competence must take into account the person's agency in making the decision, and decisions which will effectively end the person's life must be shown to be thought through. 相似文献

Previous research suggests that school-based and electronic victimization have similar negative consequences, yet it is unclear
whether these two contexts offer overlapping or unique associations with adolescents’ adjustment. 802 ninth-graders (43% male,
mean age = 15.84 years), majority being Caucasian (82%), completed measures assessing the prevalence of school and electronic
victimization, as well as self-reports on self-esteem, self-efficacy, anxiety, depressive symptoms, and locus of control.
Results revealed that the majority of adolescents did not report being victimized in either the electronic (75.3%) or the
school (72.9%) context. Victimization in both contexts was associated with lower self-esteem and self-efficacy as well as
higher stress, anxiety, depressive symptoms, and locus of control. Importantly, even after controlling for school-based victimization,
electronic victimization remained as a significant predictor for all outcome measures. Different types of electronic victimization
were also associated with different psychological outcomes. The findings suggest that it is important to distinguish between
victimization contexts and specific adjustment outcomes as school and health officials continue to battle the effects of peer
victimization. 相似文献

Behaviors that pose threats to safety and health, including binge drinking and unprotected sex, increase during a week-long
break from university. Understandings with peers regarding these behaviors may be important for predicting behavior and related
harms. College students (N = 651; 48% men) reported having understandings with their friends regarding alcohol use (59%) and sexual behavior (45%) during
Spring Break. These understandings were to engage in behaviors characterized by risk (e.g., get drunk [23.5%], have sex with
someone new [5.2%]) and protection (e.g., drink without getting drunk [17.8%], use condoms [15.8%]). After controlling for
previous semester behavior and going on a Spring Break trip, Get Drunk Understandings predicted a greater likelihood of binge
drinking and alcohol-related consequences; No/Safe Sex Understandings predicted condom use; and Sex Understandings predicted
not using condoms. Understandings with friends regarding Spring Break behavior may be important proximal predictors of risk
behaviors and represent potential targets for event-specific prevention. 相似文献

In recent years, there has been increased research focus on dating violence, producing important information for reducing these violent relationships. Yet Institutional Review Boards (IRBs) are often hesitant to approve research on dating violence, citing emotional distress of participants as a possible risk of participation. However, no known research has examined the reactions of research participants to questions about dating violence. The current study examined the reactions among college students to completing a self-report measure on dating violence. Results showed that participants reported numerous positive experiences as a result of their research participation, with only mildly increased negative emotional reactions evident for some. Findings are discussed in relation to IRB proposals and appropriate informed consent for research participants. 相似文献

Using longitudinal archival Child Welfare System (CWS) data, this study describes child health and wellbeing at their initial entrance into the CWS and subsequent returns. Associations between child wellbeing, health, placement stability, and frequency of returning to the system were also investigated. Results indicated most children were healthy and developmentally on target. In addition, emotional distress, behavioral concerns, and number of placements in the CWS were significantly correlated with placement stability. Future work should utilize the use of developmental assessments to systematically and reliably document the concerns for children in the system, and investigate factors contributing to stable placements. 相似文献

Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric via a novel and highly accurate application of supervised machine learning methods. Fitting with our expectations, we find that more ideologically extreme members, those from safer districts, and those who are not in the president’s party are more likely to send polarizing tweets, and that polarizing tweets garner more engagement, increasing campaign funding for more polarizing members. 相似文献
