This study uses longitudinal data on a sample of 10th graders to investigate the associations between self-esteem, family challenge, and 2 indicators of adolescent achievement: high school grades and extracurricular involvement. Research on self-esteem and on family challenge has linked both of these factors to achievement in adolescents, but studies have not simultaneously examined the effects of these factors on achievement. The present study finds that family challenge and self-esteem are correlated with one another, and examines the effects of each of these factors on achievement while controlling on the other factor. Controlling on self-esteem, family challenge was positively associated with grades in school, and was marginally associated with extracurricular participation. Controlling on family challenge, we did not find self-esteem to be predictive of grades or extracurricular involvement in longitudinal analyses, but we did find some evidence for a relationship in the opposite direction, with grades in 10th grade predicting self-esteem in 12th grade. Results also suggest differences in academic achievement and extracurricular participation by race/ethnicity. Implications of these findings for the role of family challenge and self-esteem in the positive development of adolescents are discussed. 相似文献

This longitudinal study was designed to test hypotheses concerning the influence of environmental changes in different groups (educational status; sex) of adolescents on their future orientation (FO). FO was measured through a free-response questionnaire on which the subjects indicated their hopes and fears (which were later categorized into various domains of life by independent judges). On a second questionnaire the subjects adjudged their present and future life in various given domains of life. The sample consisted of 24 male and 24 female adolescents, aged between 14–16 years at the time of the first measurement; the second measurement took place two years later. Half of the subjects of each sex were students at a Gymnasium (preparing for university study) at both times of measurement (high social status). The other half of the subjects of each sex were in their last year at the Hauptschule (continuation of elementary education) at the first time of measurement, and had taken up employment (e.g., an apprenticeship) by the time of the second measurement (low social status). At the time of the second measurement relatively more hopes and fears were voiced in the domains of personal development and occupation than at the first measurement. Independent of time of measurement, low-status subjects voiced relatively more hopes and fears related to the occupational domain, and boys had a more extended FO than girls. Low-status subjects — as compared to high-status subjects as well as to their own judgments at the first measurement — believed to a greater extent that the materialization of their hopes and fears depended on themselves rather than on external forces. These results support the assumption that FO cannot be dealt with as a global concept and that FO can be modified by change in the external environments, such as entry into an occupation.This study was conducted at the Sonderforschungsbereich 24, Sozial- und wirtschaftspsychologische Entscheidungsforschung, Universität Mannheim (West Germany), and financed by the Deutsche Forschungsgemeinschaft, with support from the Government of Baden-Württemberg.

ABSTRACTThis study deals with the contemporary dynamics of urban life in Bishkek. Since the dissolution of the Soviet Union, Central Asian societies have experienced widespread political, economic and socio-cultural transformations. In this context, Western or globalized cultural modes and trends influence Kyrgyzstan's social and cultural life. One of these trends is the increasingly popular coffee culture, with its attendant high-grade coffee brands and fancy cafés changing established consumption patterns. This article focuses primarily on cafés as new places of consumption and communication, but it also examines the intentions and strategies of the café pioneers. We reflect on the emergence of coffee and cafés in Bishkek and show how they have integrated in urban life as ‘third places’. Coffee is breaking away from its commonly soluble form and moving toward an expensive lifestyle product, while the new cafés offer a place for communication that has not existed before. 相似文献

Stretchmark-like tears of the inguinal region are commonly referred to as typical lesions in pedestrian accidents when the victim is run over by a motorcar. These lesions can also be observed when a pedestrian is hit by a vehicle while being in an upright position. Stretchmark-like tears are due to hyperextension or excessive abduction of the hip joint. Characteristic morphological features are variable numbers of equally superficial and parallel tears of the skin following the skin's cleavage lines. Drivers of two-wheeled vehicles may exhibit inguinal stretchmark-like tears when they hit an obstacle with their bent knee, suffering excessive abduction of the hip joint. Finally, stretchmark-like tears are described in victims of collisions with railed vehicles, of aircraft crashes and--very rarely--in severely injured car passengers. 相似文献

The withdrawal of life support from patients in persistent vegetative state (PVS) is a controversial issue, as highlighted by a continuous public debate and recent judicial decisions. In Germany, a topic of particular interest is the abatement of artificial nutrition. First, doubts have come up whether every kind of technically delivered nutrition should be rated identically or whether a distinction between feeding tubes/gastrotomies and intravenous administration should be made. Second, the question is left open whether artificial nutrition is part of basic care and as a consequence may never be discontinued, or if it has to be regarded as life-sustaining treatment which can be refused by surrogates on behalf of the nonautonomous patient. Most recently, controversial judicial decisions have dealt with the question if substituted judgement concerning abatement of artificial nutrition by surrogates or legal guardians is permitted or if the approval of a court is necessary. Forensic evidence is provided which indicates that the withdrawal of artificial nutrition in patients in the persistent vegetative state may become a contributing causative factor or even the immediate cause of death. The legal implications with regard to the above-mentioned issues of controversy are discussed. 相似文献

Most interventions by outside forces to promote democracy in post-conflict states since WWII have failed. The most successful were in societies, such as Germany and Japan, featuring relatively high per capita GNP and diversified middle class economies. Among societies in general, prospects for democracy tend to diminish as per capita GNP decreases. The effects of conflict make democracy promotion considerably more difficult, particularly when poorer societies are plagued by weak institutions, corruption, religious extremism and ethnic, religious or factional animosities. Even if outsiders are able to control violence and actively promote democracy, success will depend on the underlying political culture and willingness of key political actors to play by democratic rules once the outsiders have gone. Hence, outsiders need to develop the best possible understanding of their prospects for success before committing to intervention, particularly when the resource demands are likely to be high. 相似文献

Abstract: The authors examine the conformity with Community law of the recent regulatory changes introduced to the Italian legal system regarding the safeguarding of employees' rights during transfers of undertakings. The investigation takes place on the assumption that the principle of primacy of Community law applies, which first and foremost means that it must be verified whether the domestic legislation in question complies with the interpretation given to the relative provisions of Community law. According to the authors' opinion, domestic law could be judged as non-conforming to the interpretation that has been given by the Court of Justice, so that the question may be brought before the Court of Justice ex Article 226 EC or by recourse to the preliminary ruling procedure under Article 234 EC, which reveal cases of incorrect implementation of the Directive. 相似文献

Site‐, Technique‐, and Time‐Related Aspects of the Postmortem Redistribution of Diazepam,Methadone, Morphine,and their Metabolites: Interest of Popliteal Vein Blood Sampling 下载免费PDF全文

Sampling site, technique, and time influence postmortem drug concentrations. In 57 cases, we studied drug concentration differences as follows: subclavian vein‐dissection/clamping versus blind stick, femoral vein‐dissection/clamping versus blind stick, right cardiac chamber, and popliteal vein‐dissection and clamping only. Cases were distributed in group #1 (all cases with both techniques), group #2 (dissection/clamping), and group #3 (blind stick). Sampled drugs were diazepam, methadone, morphine, and their metabolites. To assess PMR, mean concentrations and ratios were calculated for each group. Time‐dependent variations of blood concentrations and ratios were also assessed. Results indicate that site, method, and time may influence postmortem distribution interpretation in different ways. Popliteal blood seems less subject to PMR. In conclusion, our study is the first to evaluate concurrently three main aspects of PMR and confirms that the popliteal vein may represent a site that is more resistant to the changes seen as a result of PMR. 相似文献

This symposium demonstrates the potential for throughput legitimacy as a concept for shedding empirical light on the strengths and weaknesses of multi‐level governance, as well as challenging the concept theoretically. This article introduces the symposium by conceptualizing throughput legitimacy as an ‘umbrella concept’, encompassing a constellation of normative criteria not necessarily empirically interrelated. It argues that in order to interrogate multi‐level governance processes in all their complexity, it makes sense for us to develop normative standards that are not naïve about the empirical realities of how power is exercised within multi‐level governance, or how it may interact with legitimacy. We argue that while throughput legitimacy has its normative limits, it can be substantively useful for these purposes. While being no replacement for input and output legitimacy, throughput legitimacy offers distinctive normative criteria—accountability, transparency, inclusiveness and openness—and points towards substantive institutional reforms. 相似文献

Haemorrhagic fractures of the thyroid cartilage and hyoid bone are frequently observed in cases of strangulation and often regarded as evidence for an assault against the neck. In contrast, two cases of laryngohyoid fractures after agonal falls in prone position are presented to draw attention to alternative causes of these injuries with special regard to practical medicolegal casework. A 45-year-old man collapsed at a fairground and died after unsuccessful resuscitation. He showed excoriations at his elbows and right knee, a crush injury at the mentum and his mandibular front teeth were knocked out. The upper parts of the chest and the head showed blue discolouration as a marked sign of congestion due to heart failure. The right coronary artery (RCA) was completely obturated by a 5 cm long post-stenotic thrombus with subsequent myocardial infarction of the lateral part of the left ventricle. Both superior horns of the thyroid cartilage were fractured with surrounding haemorrhage, the skin and muscles of the neck uninjured. In the second case, a 63-year-old woman with a mobility handicap had fallen from a 2m high lifting platform and was found in prone position with her wheelchair on her. Resuscitation efforts were not successful. Autopsy showed signs of blunt external force against head, neck, chest and limbs. Examination of the neck revealed haemorrhage of the right sternocleidomastoid muscle, both superior horns of the thyroid cartilage were fractured, as well as the hyoid bone, with slight haemorrhage of the surrounding soft tissue and mucosa. On the same level, the fifth intervertebral disk was ruptured, without any injury of the spinal cord. These cases demonstrate that laryngohyoid fractures should not be overestimated as unequivocal indication of neck compression and may well be caused by falls, even at ground level. 相似文献
