Numerous authors have presented evidence of increased dispersion in the distribution of annual earnings in the United States from the late 1970s through 2004 or later. However, the dispersion of long-run earnings measured over many years has received relatively little attention because of the limited availability of appropriate data. This article uses the Social Security Administration's Continuous Work History Sample, which documents the earnings histories of 3.3 million workers, to examine changes in both the annual and the long-run distributions of earnings during 1981-2004 for men and women. For men, the results indicate an increase in long-run earnings inequality of roughly the same magnitude as the trend seen in annual earnings dispersion, but there has been very little increase in the dispersion of long-run earnings among women. If calculations are restricted to a sample of women who work every year of the observation period, a trend of increased earnings dispersion emerges, but much less so than that observed for men. 相似文献

Political discussion matters for a wide array of political phenomena such as attitude formation, electoral choice, other forms
of participation, levels of political expertise, and tolerance. Thus far, research on the underpinnings of political discussion
has focused on political, social, and contextual forces. We expand upon this existing research by examining how individual
personality traits influence patterns of political discussion. Drawing on data from two surveys we investigate how personality
traits influence the context in which citizens discuss politics, the nature of the relationship between individuals and their
discussion partners, and the influence discussion partners have on respondents’ views. We find a number of personality effects
and our results highlight the importance of accounting for individual predispositions in the study of political discussion. 相似文献

The purpose of this study was to examine both the family antecedents and the outcomes of early puberty, with a particular
focus on factors related to family socioeconomic status (SES). The study employed a comprehensive measurement of pubertal
development and longitudinal data from the Canadian National Longitudinal Survey of Children and Youth. The sample (N = 8,440; 49% girls) included four cohorts of children who were followed biennially for 10 years, starting from age 4–11 to
14–21 years. Data were drawn at different years of age from these cohorts of children. Girls whose fathers were unemployed
were more likely to experience early puberty than those whose fathers were employed. For boys, those living with fathers who
had not finished secondary school were more likely to experience early puberty. Early maturing girls tended to engage in smoking
and drinking at an earlier age compared with their peers. These findings provide support for psychosocial acceleration theory
and suggest that different aspects of low family SES may act as a psychosocial stress for early pubertal maturation in boys
versus girls, which may lead to engagement in drinking and smoking at a younger age, at least for girls. 相似文献

The article presents a discussion of judicial stress, along with proposed solutions. The authors gathered information on the topic of judicial stress from judges via a survey and attendance at two Association of Family and Conciliation Courts (AFCC) conventions. Some of the daily stressors endorsed by judges included endless caseloads, severe time limitations, social isolation, lack of privacy, and the weight of deciding the fates of others. It is important for our judges to be provided with ways of relieving and preventing burnout and stress. Proposed bench stress solutions include incorporating the Psychologist Advocate Program into the judicial system and creating specific guidelines for judges to take sabbaticals, which will serve to enhance our judicial system and the entire community. 相似文献

The objective of this study was to document patterns of fracture on infant porcine skulls aged 2-28 days (n = 57) because of a single, high energy blunt impact to the parietal bone with rigid (nondeformable) and compliant (deformable) interfaces. Fracture patterns were mapped using Geographic Information System software. For the same generated impact force, the rigid interface produced more fractures than the compliant interface for all ages. This study also showed that this increased level of impact energy versus an earlier study using a lower energy resulted in new sites of fracture initiation and also caused previously defined fractures that propagate into an adjacent bone. Several unique characteristics of bone and diastatic fracture were documented as a function of specimen age, impact energy, and interface. These data describe some baseline characteristics of skull fracture using an animal model that may help guide future studies from forensic case files. 相似文献

Using desorption/ionization techniques such as easy ambient sonic-spray ionization mass spectrometry (EASI-MS), it is possible to analyze documents of Brazilian vehicles for authenticity, providing a chemical profile directly from the surface of each document. A method for the detection of counterfeit documents is described, and the falsification procedure is elucidated. Forty authentic and counterfeit documents were analyzed by both positive and negative ion modes, EASI(±)-MS. EASI(+)-MS results identified the presence of (bis(2-ethylhexyl)phthalate plasticizer and of dihexadecyldimethylammonium biocide in both types of documents. For EASI(-)-MS results, the 4-octyloxybenzoic acid additive ([M + H](+): m/z 249) is present only in counterfeit documents. It was also found that counterfeit vehicle documents are produced via Laserjet printers. Desorption/ionization techniques, such as EASI-MS, offer therefore, an intelligent way to characterize the counterfeiting method. 相似文献
