The constancy of crime hypothesis: Historical evidence from Plymouth Colony

In extending Durkheimian thought on the relationship between deviance and social order, Erikson (1966) advanced the constancy of crime hypothesis, maintaining that the volume of deviant behavior remains stable over time. Erikson's data for Essex County do show remarkable stability for the years 1651–1680 in the reported offender rate. However, Essex County represents a very limited test of the hypothesis. We present comparative historical data for the entirety of Plymouth Colony, 1633–1679, finding that change—not constancy—best characterizes the evidence. The lack of unequivocal support for the hypothesis suggests a need for its rethinking. Several such possibilities are briefly discussed.We wish to thank our colleagues David L. Smith, Charles J. Dudley, Michael Hughes, Richard Schuster, Alan C. Acock (Sociology), A. Roger Ekirch (Department of History) and the anonymous reviewers ofQualitative Sociology for their helpful suggestions on a prior version of this paper. The research was made possible by a small project grant from VPI & SU, and we gratefully acknowledge the assistance of Catherine L. Hammond in completing the investigation.     

Markov bridges and enlarged filtrations

The semimartingale decomposition of a Markov chain, whose value at some future time is known, is obtained by considering an enlarged filtration.     

Characterizations based on Rényi entropy of order statistics and record values

Two different distributions may have equal Rényi entropy; thus a distribution cannot be identified by its Rényi entropy. In this paper, we explore properties of the Rényi entropy of order statistics. Several characterizations are established based on the Rényi entropy of order statistics and record values. These include characterizations of a distribution on the basis of the differences between Rényi entropies of sequences of order statistics and the parent distribution.     

Individual Differences in Women's Salivary Testosterone and Estradiol Following Sexual Activity in a Nonlaboratory Setting

Objectives: The current study evaluated women's salivary testosterone and estradiol levels before and after exposure to sexual stimuli in a U.S. sex club. Methods: Behavioral data and salivary samples were collected from 19 women during semistructured interviews. Results: Findings demonstrate substantial individual differences in the magnitude and direction of women's hormonal changes following sexual activity. Conclusions: In an age of individualized medicine, these findings highlight the need to better understand factors shaping variation in physiological responses to sexual activity. Findings contribute to a relatively small and contradictory literature on women's hormonal responses to sexual stimuli.     

Does Drinking Alcohol Prior to Sexual Activity Influence College Students’ Consent?

Objectives: This study assessed the extent to which consuming alcohol prior to sexual activity influenced college students' verbal/behavior cues utilized to communicate consent (external consent) as well as their feelings associated with consent (internal consent). Methods: Data was collected via paper-and-pencil surveys administered to heterosexual college students (N = 794) in the United States. Results: After controlling for gender, relationship status, rape myth acceptance, and alcohol expectancies, findings indicated that alcohol consumption prior to sexual activity was associated with both internal and external consent. Conclusions: Current findings can help inform sexual assault prevention education programming given the high rates of sexual assault occurring on college campuses that involve alcohol consumption.     

基于医疗质量实时监控系统的运行病历书写质量研究

目的:研究医疗质量实时监控系统是否可以提高运行病历的书写质量?方法:对实时监控前后共四年的运行病历书写质量进行回顾性分析,监控前共抽查960份运行病历,监控后检查24 255份运行病历,从运行病历书写的及时性?完整性?内涵质量三方面进行汇总分析?结果:监控前组和监控组比较,及时性达标率由79.4%提升到85.2%(P < 0.001),完整性达标率由94.9%提升到98.2%(P < 0.001),内涵质量达标率由91.8%提升到93.6%(P = 0.114);监控后第二年(2013年)发现运行病历书写及时性?完整性?内涵质量不达标情况分别集中在危重患者病程记录不及时?入院录不完整?日常病程记录内涵质量不高等方面;运行病历书写质量受书写人员的性别?学历?职称?科室因素影响?结论:医疗质量实时监控系统的应用是提高运行病历书写及时性?完整性的有效方法,但对提高运行病历书写的内涵质量效果不明显;女性?高职称?高学历?非手术科室的医务人员运行病历书写的质量较高?     

Diesel Engine Exhaust and Lung Cancer Mortality: Time‐Related Factors in Exposure and Risk

To develop a quantitative exposure‐response relationship between concentrations and durations of inhaled diesel engine exhaust (DEE) and increases in lung cancer risks, we examined the role of temporal factors in modifying the estimated effects of exposure to DEE on lung cancer mortality and characterized risk by mine type in the Diesel Exhaust in Miners Study (DEMS) cohort, which followed 12,315 workers through December 1997. We analyzed the data using parametric functions based on concepts of multistage carcinogenesis to directly estimate the hazard functions associated with estimated exposure to a surrogate marker of DEE, respirable elemental carbon (REC). The REC‐associated risk of lung cancer mortality in DEMS is driven by increased risk in only one of four mine types (limestone), with statistically significant heterogeneity by mine type and no significant exposure‐response relationship after removal of the limestone mine workers. Temporal factors, such as duration of exposure, play an important role in determining the risk of lung cancer mortality following exposure to REC, and the relative risk declines after exposure to REC stops. There is evidence of effect modification of risk by attained age. The modifying impact of temporal factors and effect modification by age should be addressed in any quantitative risk assessment (QRA) of DEE. Until there is a better understanding of why the risk appears to be confined to a single mine type, data from DEMS cannot reliably be used for QRA.     

Examining the Interplay of Career,Migration and National Cultural Identity: The Case of Indian Scientists

In this paper, we examine individuals’ career migration across international borders. It is widely recognized that globalization has fundamental implications for the careers of people across geographical and cultural boundaries. However, our understanding of the interplay of migration, career development and national/cultural identities remains undeveloped within the extant literature. In this paper, we seek to offer insights into this relationship. Focusing on Indian scientists, an occupational group whose careers have long been associated with movement around the world, in this paper we examine these issues. Empirically, we examine three themes: why Indian scientists see international mobility as important in the development of their careers; continued links with India; and the interplay of national/cultural affiliation and respondents’ career experiences. In light of our findings, in the discussion section we argue that considering Indian scientists as a career diaspora highlights three important features that in the main have received only limited attention in the extant literature: career as a social form and process; the notion of the scientific career as a cultural product; and the interrelationship of career and national/cultural affiliation as ongoing facets of individuals’ identities as they develop diasporic careers.
