Early puberty is associated with stressful family environments, early sexual intercourse, and teenage pregnancy. We examined
pubertal timing and sexual debut among the 14-year-old offspring of teenage mothers. Mothers (71% Black, 29% White) were recruited
as pregnant teenagers (12–18 years old). Data were collected during pregnancy and when offspring were 6, 10 and 14 years old
(n = 318). Adolescents (50% male) compared the timing of their pubertal maturation to same-sex peers. There was a significant
3-way interaction effect of race, sex, and pubertal timing on sexual debut (n = 305). This effect remained significant in a model controlling for maternal age at first intercourse, substance use, exposure
to trauma, authoritative parenting, and peer sexual activity (n = 255). Early maturation was associated with early sex in daughters, and may be one pathway for the inter-generational transfer
of risk for teenage pregnancy among daughters of teenage mothers. 相似文献

The harm caused by many acts is not certain but probabilistic. Current public enforcement of the law combines harm-based sanctions
(usually in criminal law) with act-based sanctions (very common in administrative law and regulation). We propose an economic
theory of the choice between harm-based and act-based sanctions in public enforcement. The efficiency of act-based versus
harm-based sanctions is analyzed and a typology of the determinants is drawn up. Our model suggests that harm-based sanctions
are more efficient when (1) acquiring information about the act is important, (2) engaging in harm avoidance activities is
advisable, (3) judgment-proofness is not a very significant problem, (4) punishment is especially costly, (5) changes in law
are expensive or difficult to negotiate and (6) on average, potential criminals are better informed than the government about
losses for society. Legal policy implications are discussed. 相似文献

The nanotechnology and biotechnology “revolutions” are so-called because their enabling technological breakthroughs were not
simply inventions, but discoveries of entirely new methods of inventing. We hypothesize that university participants in either
or both of these areas will exhibit greater collaboration with industry than researchers in other areas. We explore this hypothesis
for 454 faculty members who conducted research that was patented during the period 1994–1999. Because our data include patents,
publications, and funding at the individual level, we are able to examine the industry interaction of faculty who participated
in the nanotechnology and biotechnology revolutions, as well as the interaction of faculty contributing to other areas of
patentable science. We examine a variety of linkages, including sponsored research, consulting, publication with firm employees
and measures of the potential for cross-campus collaboration. The results are striking in that they show significant differences
in collaborative behavior across patent types and across the major program areas biological sciences, physical sciences and
engineering. The results are consistent with a greater degree of tacit knowledge within the new methods of inventing. We also
find significant differences in the embryonic nature and importance of patents across areas. 相似文献

This comment explores whether health care reform legislation establishes an administrative body effectively charged with the rationing of health care resources; insofar as it establishes a presidentially appointed Independent Medicare Advisory Committee (IMAC). IMAC would be charged with "making two annual reports dictating updated rates for Medicare providers including physicians, hospitals, skilled nursing facilities, home health, and durable medical equipment." IMAC's recommendations would be implemented nationally, subject to a Congressional vote. Congress would be granted a thirty-day window to achieve a simple majority for or against the IMAC recommendations. Part I is an introduction. Part II of this article covers the history of American health care. It lays out the federal government's evolving role in the arena of public health and health care, starting in the mid-nineteenth century and continues up to the present day. Part III examines the existing process by which Medicare spending is controlled. This part focuses on the administrative procedures that control Medicare reimbursements. Part IV examines IMAC. This part discusses IMAC's statutory provisions and the administrative transparency laws IMAC would be bound to follow. The close of this part, draws on three analogies as a gauge for how IMAC will operate: Senator Tom Daschle's Federal Health Board (FHB) proposal; the administrative oversight of the Federal Reserve; and the United Kingdom's National Institute for Health and Clinical Excellence (NICE). Part V creates a snapshot of the U.S. health care system as it operates today. This part emphasizes cost, quality, and accessibility of health care, with comparisons to international and state-run health care systems. Throughout this article there are a number of words, phrases, and agencies that have been given acronyms. For convenience, an index of these acronyms is provided in an appendix following the article. 相似文献

Globalization has led to new health challenges for the twenty-first century. These new health challenges have transnational implications and involve a large range of actors and stakeholders. National governments no longer hold the sole responsibility for the health of their people. These changes in health trends have led to the rise of global health governance as a theoretical notion for health policy making. The Southeast Asian region is particularly prone to public health threats such as emerging infectious diseases and faces future health challenges including those of noncommunicable diseases. This study looks at the potential of the Association of Southeast Asian Nations (ASEAN) as a regional organization to lead a regional dynamic for health cooperation in order to overcome these challenges. Through a comparative study with the regional mechanisms of the European Union (EU) for health cooperation, we look at how ASEAN could maximize its potential as a global health actor. Our study is based on primary research and semistructured field interviews. To illustrate our arguments, we refer to the extent of regional cooperation for health in ASEAN and the EU for (re)emerging infectious disease control and for tobacco control. We argue that regional institutions and a network of civil society organizations are crucial in relaying global initiatives, and ensuring the effective implementation of global guidelines at the national level. ASEAN’s role as a regional body for health governance will depend both on greater horizontal and vertical integration through enhanced regional mechanisms and a wider matrix of cooperation. 相似文献

This article looks at collective memory formation—the study of monuments, memory, and public space—through a political science lens. An explicit theoretical focus on power relations in "monumental politics" and a methodological approach featuring large-N comparative analysis are combined to examine the process of monument creation, destruction, and alteration. Using a new database on monuments in 26 post-communist states over a 25-year period, patterns of monument transformation are identified, and official and private efforts to transform monuments are systematically compared across different regime types. The complex implications of private provision and alteration of monuments is also discussed. 相似文献

Abstract This paper analyses work, childcare, and earnings of mothers in the slums of Guatemala City and Accra. Similar factors affect decisions to work and to use formal daycare, but the importance of childcare varies with the role of the formal labour sector. In Guatemala, where formal sector work is important, higher prices for informal care increase formal daycare use. However, daycare prices and proximity to daycare centers do not significantly affect earnings in Guatemala City and Accra, respectively. Providing formal daycare may be more important to mothers' decision to work in cities where formal sector work dominates. 相似文献

During forensic anthropological investigation, biological profile is determined by age, sex, ancestry, and stature. However, several individuals may share the same profile. Observation of discrete traits can yield useful information and contribute to identification. This research establishes the frequency of discrete traits of the sternum and ribs in a modern population in southern France, using 500 computer tomography (CT) scans of individuals aged 15–60 years. Only discrete traits with a frequency lower than 10% according to the literature were considered, a total of eight traits. All scans examined were three‐dimensional (3D) volume renderings from DICOM images. In our population, the frequency of all the discrete traits was lower than 5%. None were associated with sex or age, with the exception of a single trait, the end of the xiphoid process. Our findings can usefully be applied for identification purposes in forensic anthropology and medicine. 相似文献
