With substantive evidence suggesting that adolescents’ disclosure is likely a protective factor against problem behaviors, as well as evidence that many adolescents will go to great lengths to avoid sharing information with parents, one may conclude that parents’ face a formidable task. Previous studies have identified parental acceptance as a concurrent correlate of adolescents’ behavioral disclosure, but have neglected to investigate potential ways that parents could encourage their adolescents to feel comfortable disclosing emotional information. The present study extends the literature by using a longitudinal, multi-method, multi-reporter design to examine whether maternal acceptance is predictive of emotional disclosure over time among a racially/socioeconomically diverse sample of 184 adolescents (53% female). Results indicate that adolescents who perceive their mothers as high in acceptance during early adolescence exhibit greater relative increases in both self-reported emotional communication and observed emotional disclosure to their mothers 3 years later. Interestingly, mothers’ perceptions of their own acceptance does not provide any additional predictive value. These findings support the notion that adolescents’ emotional disclosure is an ongoing process that can be fostered in early adolescence, and emphasize the importance of considering adolescents’ perceptions of the relationship to successfully do so.  相似文献

The 2015–17 Parliament was the first time in history that the Conservatives were in government with no easily assembled majority in the House of Lords. This has fundamentally altered the role that Labour is able to play in the Lords and, conversely, that peers are able to play in the Labour party. Yet the political significance of this situation has not yet been fully appreciated by a party which remains culturally antagonistic and constitutionally wary of the Lords. In this paper, we draw on interviews with Labour peers, particularly the late Baroness Hollis of Heigham, who have been able to use the essentially conservative powers of the Lords for social democratic ends. We suggest that the Labour party needs to incorporate the second chamber into both its practical and symbolic politics, and to find ways to use this new source of constitutional power without accommodating to it.  相似文献

Abstract: Sex is one of the critical questions addressed when unidentified skeletal remains are discovered in forensic or archeological contexts. Continuous testing and re‐evaluation of existing techniques is essential to improve accuracy and precision. The Wescott (J Forensic Sci 2000; 45 (2):462–6) method of sex determination from dimensions of the second cervical vertebra was blind‐tested on 153 adult individuals from the Spitalfields documented collection of human skeletal remains held at the Natural History Museum, London. Significant sex differences were determined for all dimensions measured (independent two‐sample t‐test, p < 0.05–0.001). The discriminant functions developed by Wescott were shown to have an overall accuracy of classification of 76.99%. Using stepwise discriminant analysis, a discriminant function based on the Spitalfields data correctly classified sex in 83.3% of individuals and was able to classify males and females with equal accuracy. Additional discriminant functions are presented for use in instances where preservation of the second cervical vertebra is poor.  相似文献

During the analysis of "seized samples", suspected of containing 4-methylmethcathinone (mephedrone) and N-ethylcathinone (ethcathinone) additional compounds were observed in the GCMS chromatogram. These compounds were suspected to be the corresponding phenylacetone isomers of mephedrone and ethcathinone respectively. These isomers are referred to as iso-mephedrone and iso-ethcathinone, respectively. The identity of these compounds was verified by synthesising the isomers from known starting materials and comparing them with the compounds found in the seized samples. Analytical data, GCMS, NMR and IR on these compounds are provided. Possible explanations for the presence of these compounds in the seized samples are explored. Contaminated starting material is one suggestion. Rearrangement of the propiophenone based product to the phenylacetone based product is also suggested. The reaction of the α-bromopropiophenone with a primary amine can also lead to the phenylacetone based product. The presence of these isomeric compounds in seized samples could be used to compare different samples and attempt to establish a common origin.  相似文献

The ring substituted methyl isomers of methcathinone, 2-, 3- and 4-methylmethcathinone were analysed. The 2- and 3-isomers were synthesized. The 4-methylmethcathinone isomer is also known as mephedrone and has been widely studied. We present GCMS, NMR and IR data for the three isomers. We show that the three isomers can be separated by GCMS and that the IR spectra for the three compounds can be used to distinguish between them. A seized sample was analysed and it was found to contain 4-methylmethcathinone and benzocaine.  相似文献

Sixty years before Carl Schmitt wrote his Political Theology, and more than a 100 years before President Bush announced a ‘war on terrorism’ the American Supreme Court grappled with the difficult issue of emergency powers in connection with issues arising out of the American Civil War (1861–1865). The question confronting the Court in a set of cases named the Prize Cases was whether President Lincoln’s decision to respond to acts of aggression by the secessionist Southern states with measures of war was lawful. The legal problem was that Lincoln had made this decision unilaterally although the American Constitution specifically allocates the power to declare war to Congress. The Court solved the dilemma by arguing that in cases where no war has been declared, the decision whether the country is in a state of war is ultimately ‘a question to be decided by him [the President], and [the Supreme] Court must be governed by the decisions and acts of the political department of the Government to which this power was entrusted’ (Prize, p. 669). The precedent, which the Court thereby laid down, has since played out as an important leverage for the Bush government’s legal arguments in connection with the war on terrorism. This article engages the theoretical framework of Locke, Schmitt and Agamben in order to come to a better understanding of this important set of cases.  相似文献

The central issues raised in much of feminist literary theory's early scholarship remain prescient: how does narrative engage with the social‐historical? In what ways does it codify existing structures? How does it resist them? Whose stories are not being told, or read? In this article I use Doris Lessing's novel The Fifth Child (1988) as a text with which to begin to address the above questions by reading with attention to the mother story but also the ‘other’ stories operating both within and outside of the novel; in particular I am concerned with the convergence of maternity, disability and narrative. The novel's co-implication of sexual difference and corporeal difference reveals the ways in which the mother's story is both made possible and authorized by the disabled body of her child, and by his inability to tell his own story. Yet, if The Fifth Child is a horror story that uses the disabled child's body as its ground, it is also about the horror of maternity, in its conception and attendant choices. In this fictional story as well as in the social‐historical narrative circulating at the time of its publication in the late 1980s, both child and mother are indicted in their otherness and it is ultimately impossible to separate one from the other.  相似文献

Reducing failures to appear (FTA) in court is a top priority for criminal justice practitioners and advocates. However, existing work on reducing FTAs through text message reminders focuses on large urban jurisdictions and defendants who are housed. Using a field study in Shasta County, California, we evaluate whether text message outreach can increase court appearances for housed and unhoused populations. We find housed defendants randomly assigned to the treatment group were 10% less likely to miss their next scheduled court date than defendants in the control group. We find no statistical difference in the FTA rate of unhoused individuals assigned to treatment or control groups, and cannot rule out large positive or negative effects. We find that improving the quality of contact information in court records could lead to large reductions in FTAs. Partnering with local social service providers may not, but more research is needed.  相似文献
