A perspective on the research literature from 1960 to 1970 concerning pregnant adolescents (this literature was abstracted and reviewed in a previous publication) is presented. Research methodology and potential content for research are examined and suggestions made that would contribute to a stronger empirical base for the research. Several assumptions (of difference, of homogeneity, and of special need) regarding pregnant adolescents that seem to be implicit in the research are brought to light. Finally, an analysis of the risk concept is presented.Has degrees in social work (M.S. and Ph.D.) and public health (M.S.), with research interests in adolescent health status, human service for youth, and the process of (research) consultation.Has M.A. in sociology.Has degrees in theology (B.D.) and medical sociology (Ph.D.). He teaches the latter, while focusing his research interests on the mental health consequences on women as a result of their labor force participation and the evaluation of accelerated medical education programs.M.D. degree and a degree also in public health. Before his academic career, he was a high public official in the New York State Department of Health. His publications include studies of the medical aspects of water fluoridation and high-risk groups receiving maternity care. Current research interests include studies of patterns of provision of maternal and child health services in the United States, the incidence and prevalence of long-term diseases of childhood, and followup studies of low birth weight and other vulnerable infants.  相似文献

The purpose of this study was to examine the relationship between neonatal behavior and prenatal and perinatal risk factors in infants of teenage and older mothers in Puerto Rico and Mainland United States. The sample included approximately 300 newborn infants;half were examined in Puerto Rico, the other half in Florida, using the Brazelton Neonatal Behavioral Assessment Scale. Comparisons by maternal age and the number of obstetrical complications showed that for the Puerto Rican group, infants with fewer obstetrical complications were better able to regulate their crying and active states. Infants of teenage mothers with fewer complications had a higher level of arousal than infants of older mothers with fewer complications. Infant behavior in the Mainland sample did not vary by maternal age or complications. Multiple regression analysis indicated that the combination of biomedical variables significantly predicted neonatal behavior in both cultures. Mother's age was not separately correlated with neonatal behavior, but was repeatedly combined with other variables in the significant regressions. The findings suggest that infants of teenage mothers may differ from infants of older mothers, particularly in the organization of state behavior, and that the effects of maternal age on neonatal behavior are increased in the presence of biological outcome factors.This article is based on a final report to the NICHD Center for Population Research, Contract N01-HD-7283.Received Ph.D. from Michigan State University. Main research interests are determinants of neonatal and infant development, assessment of preterm and at risk infant.Received Ph.D. from Harvard University. Main research interests are sociocultural aspects of development, teenage pregnancy, infant temperament and psychophysiology.Received M.A. from University of Florida. Main research interests are prenatal and prenatal factors on development, maternal obstetric medication, and behavioral teratology.  相似文献

Objectives

The previous 25 years have witnessed remarkable upheavals in the social landscape of the United States. Two of the most notable trends have been dramatic declines in levels of crime as well as teen childbearing. Much remains unknown about the underlying conditions that might be driving these changes. More importantly, we do not know if the same distal factors that are responsible for the drop in crime rates are similarly implicated in falling rates of teen births. We examine four overarching potential explanations: fluctuations in economic opportunity, shifting population demographics, differences in state-level public policies, and changes in expectations regarding health and mortality.

Methods

We combine state and year-specific data from existing secondary sources to model trajectories of violent crime and teen fertility over a 20-year period from 1990 to 2010 using simultaneous fixed-effects regression models.

Results

We find that 4 of the 20 predictors examined—growth in the service sector of the labor market, increasing racial diversity especially among Hispanics, escalating levels of migration, and the expansion of family planning services to low-income women—offer the most convincing explanations for why rates of violent crime and teen births have been steadily decreasing over time. Moreover, we are able to account for almost a quarter of the joint declines in violent crime and teen births.

Conclusions

Our conclusions underscore the far reaching effects that aggregate level demographic conditions and policies are likely to have on important social trends that might, at first glance, seem unrelated. Furthermore, the effects of policy efforts designed to target outcomes in one area are likely to spill over into other domains.

Previous research by the authors on an animal model showed that bloodstains can contain additional information about their somatic origin in the form of wound cells. Bloodstains produced by a gunshot wound to the head were distinguished from bloodstains produced by a gunshot wound to the chest by testing the stains for a brain microRNA marker. In this study, the effectiveness of the technique was examined on blood drops shed externally from a stab wound to the liver of rat carcasses. Specifically, investigations were conducted on the liver microRNA marker, rno‐mir‐122‐3p, with the QIAGEN miScript System, and PCR analysis. Between the two stabbing methods used, 67% of the scalpel blades and 57% of the blood drops tested positive for rno‐mir‐122‐3p; however, other samples tested negative giving inconclusive results as to the wound‐of‐origin. The amount of the liver cells in the bloodstains appeared to be related to the extent of trauma.  相似文献

In the wake of our nation's financial crisis, protection against insurer insolvency is more critical than ever to the insurance-buying public. All U.S. jurisdictions provide partial statutory protection in the event of insurer insolvency through the creation of various state insurance guaranty associations that are governed by statutes primarily based on a model act promulgated by the National Association of Insurance Commissioners. Guaranty associations are an integral part of each state's regulatory process for addressing insurer insolvency. Through a matrix of state-specific enabling statutes, state insurance guaranty associations levy and collect assessments from member insurers, pay statutorily defined “covered” claims, and defend against appropriate claims that are in litigation. Together with the domestic regulator of the insolvent insurer (usually the commissioner or superintendent of insurance) and the deputy liquidator (typically approved by the court presiding over the liquidation process and selected by the commissioner or superintendent of insurance as statutory liquidator), the guaranty association community (comprised of associations located in virtually each state in which a policyholder resides) functions as a unified system to manage and at least partially mitigate the impact of an insurer insolvency.  相似文献

Morale among U.S. federal employees has increased but remains low compared to the private sector and in certain agencies, including the Department of Veterans Affairs (VA), which has experienced scandal and management challenges, including a crisis of leadership. Using data from the 2015 Federal Employee Viewpoint Survey, this article examines the influence of transformational leadership (TFL) on job satisfaction/commitment among VA employees. Regression analysis reveals a positive association between satisfaction/commitment and each of the four TFL dimensions, controlling for the other dimensions and sociodemographic characteristics. Employees who perceive leaders as fostering creativity, empowerment, trust/respect, and clear goals/expectations are more satisfied/committed.  相似文献

The published collection of Jean Rhys's correspondence opens with two undated photographs of Rhys on facing pages. The author's pose is nearly identical in the two images: her head rests on her hands and her large, dark eyes, rimmed with black liner, look directly out at the viewer. In both pictures, Rhys's hairstyle is exactly the same - though the colour and texture have changed - and the vivid pattern on her clothing is also similar. Both are portraits of a strikingly beautiful woman, and together they suggest a narrative embodying several concerns central to Rhys's early fiction: the exhibition of feminine beauty, the passing of time, and the social, biological and economic consequences of ageing for women. The strong continuities between the two photos, along with their striking differences, serve as a visual representation of the need for women to appear unchanging, to weave a narrative or create an image of the self that keeps the past and present contemporaneous in order to maintain value in the sexual marketplace. The inter-relations of gender, value, age and expenditure suggested by the two photographs are articulated in Jean Rhys's early novels, which depict the economy of investment and loss that women face as they age. In Rhys's texts - and particularly in her two first-person narratives - there is an attempt to recreate in prose the simultaneous experience of past and present, not simply as an example of modernist experimentation with narrative continuity, but also as a specifically gendered response to the economic and social consequences of ageing for women.  相似文献
