Identity is a critical developmental task during the transition to adulthood in Western societies. The purpose of the present study was to evaluate an empirically based, cluster-analytic identity status model, to examine whether all four of Marcia's identity statuses (diffusion, foreclosure, moratorium, and achievement) would emerge empirically, and to identify different patterns of identity formation among American college-attending emerging adults. An ethnically diverse sample of 9,034 emerging-adult students (73% female; mean age 19.73?years) from 30 U.S. universities completed measures of identity exploration (ruminative, in breadth, and in depth) and commitment (commitment making and identification with commitment), identity synthesis and confusion, positive and negative psychosocial functioning, and health-compromising behaviors. The identity status cluster solution that emerged provided an adequate fit to the data and included all four of Marcia's original identity statuses, along with Carefree Diffusion and Undifferentiated statuses. Results provided evidence for concurrent validity, construct validity, and practical applicability of these statuses. Implications for identity research are discussed. 相似文献

The aim of this pilot study was to investigate compositional changes in bone during decomposition. Elemental concentrations of barium, calcium, iron, potassium, magnesium, zinc and phosphorus in porcine bone (as an experimental analog for human bone) were analyzed by inductively coupled plasma optical emission spectroscopy (ICP‐OES). The samples were taken from porcine bone subjected to shallow burial and surface depositions at 28‐day intervals for a period of 140 days. Results indicated that ICP‐OES elemental profiling has potential to be developed as a forensic test for determining whether a bone sample originates from the early stages of soft tissue putrefaction. Significant changes in iron, sodium and potassium concentrations were found over 140 days. These elements are known to be primarily associated with proteins and/or tissue fluids within the bone. Changes in their respective concentrations may therefore be linked to dehydration over time and in turn may be indicative of time since deposition. 相似文献

In this study, we present the data concerning 10 children (six boys, four girls) with a diagnosis of foreign body aspiration (FBA) amongst 19,951 cases that underwent autopsy between the years 1996-2002. Eight of the children were under 2 years old. All the incidents took place at home. One of the parents was in the company of the child at the time of incident. At least one of the risk factors was positive. Interestingly, all of the aspirated material was related to food except one. Only four cases had subpleural petechiae, whereas five of the seven subjects undergoing histopathological evaluation had edema, hyperemia or intra-alveolar fresh bleeding. The legal instructions, which regulate the standards of toy materials, came into force at the end of 2003. Even though the legal instructions regulating the size and consistency of toys are very important to prevent FBA, we believe that the education of the parents and carers in the prevention of food aspiration is of greater importance. 相似文献

A new type of heroin HCl seized in Australia was examined by stable isotope analysis. The final origin/process classification of these samples by chromatographic signature profiles of the impurity/manufacturing by-products was previously determined to be "unknown" by two independent national laboratories. Various drug enforcement authorities speculated that the heroin might be from a new region or new illicit process due to the unusual chromatographic impurity profiles that were present. Samples from 20 different kilogram packages were examined for isotopic content to determine if the samples fit isotopic patterns of known origins or if they were unique to any known origins. Authentic specimens from Southeast Asian (N=59), Southwest Asia (N=37), South America (N=104), and Mexico (N=21) we concomitantly examined for comparison purposes. Both continuous flow elemental analysis-isotope ratio mass spectrometry and gas chromatography-isotope ratio mass spectrometry techniques were utilized. Heroin samples were also converted to morphine, without apparent isotopic fractionation, utilizing methanolic HCl for gas chromatography-isotope ratio mass spectrometry. The Pong Su samples were found to be isotopically and isotopically/alkaloidally distinct from the known origin/process classifications of Southwest Asian, Southeast Asian, South American, and Mexican. 相似文献

Examination of the cardiac conduction system: forensic application in cases of sudden cardiac death 总被引:1,自引:0,他引:1
Gulino SP 《The American journal of forensic medicine and pathology》2003,24(3):227-238
Forensic pathologists may occasionally encounter cases of apparent sudden cardiac death without gross cardiac abnormality. In some of these cases, evaluation of the cardiac conduction system may reveal pathologic lesions which may act as the substrates for ventricular tachyarrhythmias and sudden death. Sample case studies are used to illustrate the suggested criteria and techniques for examination, and commonly-encountered pathologic lesions and normal variants are discussed. 相似文献

The focus of this article is organizational behaviour in and around the private sector in Tanzania at a time of transition through liberalization and the promotion of private sector activity; how the private sector has re‐emerged in the very recent past; how it operates as a group or, more accurately, as a set of groups, and the relationships between its component parts and with other development organizations (notably public actors: the state and aid donors). Within this framework our interest is in how organizational behaviour is mediated and trust is built through the brokering of relations between different organizations which intersect the public and private (and what this means for the public sphere). The article assesses the usefulness of a three‐level framework for analysing organizational and institutional transformation, shows that some tentative but modest change is occurring, and that a range of incomplete but positive political processes are happening. We show that institutional development is the weak link in these processes. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献
