Based on equity theory, the present study analyzes to what extent justice evaluations mediate the effects of perceived parental differential treatment (PDT) on relationship quality with siblings and parents as experienced in middle adulthood. Middle-aged adult offspring (N = 709) rated how often they and a sibling received parental recognition, nurturance, and demands for assuming filial responsibility. In addition, they indicated their justice evaluations of PDT and completed measures of relationship quality to sibling and parents. Justice evaluations emerged as either partial or complete mediators between PDT and relationship quality. Moreover, justice evaluations turned out to be more powerful predictors of relationship quality to parents than PDT per se. Implications are discussed concerning factors contributing to justice evaluations and the role of PDT within the context of other justice issues in families. 相似文献

In the context of European Union enlargement and the discussions about a European constitution, the question of Europe's identity has once again entered the limelight of political debates. From a poststructuralist perspective, identities are constructed through practices of othering, articulating a difference. In this article, I follow Ole Wæver to argue that for most of the time after the Second World War the most important other in the construction of a European identity has been Europe's own past. This temporal form of othering offered the possibility to form an identity through less antagonistic and exclusionary practices than was common in the modern international society. However, since the 1990s geographic and cultural otherings are on the increase, marking a return of geopolitics in European identity constructions and undermining the notion of European integration as a fundamental challenge to the world of nation‐states.1 相似文献

This paper examines the variation in receptivity to mitigation evidence by capital jurors as it varies by the race of the juror, defendant, and victim individually and in combination. Attitudinal and racial characteristics from 865 respondents in the Capital Jury Project were used in the analysis. Using a generalized form of multiple regression, the respondent's receptivity to mitigation evidence was predicted and changes in receptivity were calculated as the race of the main trial participants (juror, defendant, and victim) were varied. Statistical controls were put in place for gender of respondent; respondent's perception of the dangerousness of the defendant, heinousness of the crime, and view of the defense attorney; respondent's formation of a premature sentencing decision; and whether the trial took place in a southern state jurisdiction. Results indicate that Black jurors in cases where a Black is charged with killing a White victim are chiefly responsible for the observed variance in receptivity to mitigation. 相似文献

The procedure used in this laboratory for removing and identifying contamination of hair specimens with drugs is demonstrated by its application to hair contaminated by various experimental models. The models include soaking; coating with drug followed by sweat conditions for 6 h; and soaking in a very high concentration of cocaine followed by storage and multiple shampoo treatments. A multi-part wash procedure along with a wash criterion is applied to all samples containing drug above the cutoff. The failure of the wash criterion is a signal that the sample may be positive due to contamination rather than use, and in the absence of other over-riding evidence, the sample would be considered to be negative for drug use. This Wash Criterion has also been tested with hair from subjects demonstrated to be drug users by one or more drug-positive urines; in these studies, all hair samples from demonstrated users passed the Wash Criterion test. 相似文献

Vitreous humor is a suitable specimen for postmortem clinical chemistry because the analytes remain relatively stable after death and they closely reflect blood levels immediately prior to death. The viscous nature of vitreous fluid, however, presents analytical problems including imprecision and inaccuracy. Various preanalytical treatments, such as boiling, high speed centrifugation, microfiltration and dilution have been used. These techniques are labor intensive and add to imprecision and inaccuracy. Because glycosaminoglycans contribute significantly to the viscosity of vitreous humor, we used hyaluronidase as a liquefying agent. We compared the results of analyses in 33 vitreous humor specimens after hyaluronidase treatment with the results after either no treatment or specimen dilution. Seventeen of the 33 specimens could not be analyzed without dilution. Even after dilution, several analytes still could not be measured. Hyaluronidase treatment negated the need for sample dilution and had no significant effect on the analyses. 相似文献

Literature assessing knowledge of and attitudes toward social issues has demonstrated that mental health professionals and lay persons often differ greatly. To add to the normative information in the field of psychological abuse and to determine whether the differences previously found between mental health professionals and lay persons extend to this field, a sample from each group rated psychologically aggressive items by a husband toward his wife. For the 102 items, psychologists were more likely to label the behaviors as "psychological abuse," but this tendency was due to psychologists considering the behaviors as either "always" or "possibly" abusive, whereas lay persons demonstrated a bimodal response pattern of rating the behaviors as "always" or "never" psychological abuse. Lay persons were much more likely than psychologists to rate items high in terms of severity level, however. The two groups used different contextual factors for determining that a behavior was psychological abuse when they initially were uncertain that it was abusive. 相似文献
