The career stage theory postulates that employees go through different career stages, and each career stage has different effects on various outcomes, such as job satisfaction. There has been empirical support for the career stage theory from other disciplines, but there has been limited research relating to this theory to corrections. To expand the literature, the current study examined whether different career stages were significant predictors of job satisfactions, while including the personal characteristics and the workplace place variables among Texas correctional officers. The results supported the career state theory: job satisfaction was highest during the entry stage (0–2 years), but was lowest during the second career stage (2–5 years). In career stages three (5–15 years) and four (16+ years), job satisfaction rose. Possible interventions that correctional administrators can undertake to encourage job satisfaction from their staff during the second career stage are discussed.  相似文献

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

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

Studies of public support for capital punishment have consistently observed a strong and enduring gender gap in the level of death penalty support, with males consistently more inclined than females to support capital punishment. This unexplained relationship has endured over time and space as well as across a myriad of research designs. The present study uses attribution theory in a factorial survey design to account for this relationship. Analyses of data obtained from jurors provide mixed support for attribution theory yet fails to bridge the gender gap in death penalty support. The implications of these findings as they relate to gender, socialization, and attributions are discussed.  相似文献
