The purpose of this study was to examine the nature and extent of mutual violence among a sample of pregnant and parenting Latina adolescent females and their partners. The sample consisted of 73 Latina adolescent females between the ages of 14 and 20 who were referred to a community-based organization for case management, education, and psychosocial support for pregnant and parenting adolescents. They completed the Conflict Tactics Scale (CTS-2) as part of a pretest to evaluate this intervention program. A small number (12 out of 73; 16%) reported no use of aggressive conflict tactics. Eighty-four percent (61 out of 73) of the study respondents reported using at least one form of minor psychological aggression and 62% (45 out of 73) reported using at least one form of minor physical assault over the past 6 months. Mutuality of conflict was high, especially in cases of minor assault by partner. There was no difference in severity or chronicity of conflict between those who were pregnant and those who were not. Female respondents reported that they and their partners engaged in comparable levels of sexual coercion. Discussion of the context of psychological, physical, and sexual aggression in adolescent relationships suggests alternative approaches to prevention of intimate partner violence among adolescents. 相似文献

Election forecasting has experienced considerable growth as a subfield within political science. Research work on United Kingdom elections has been cutting edge here. The recent 2010 general election afforded the opportunity for a trial of different forecasting methodologies. These efforts are showcased in this volume, and include standard, and not-so-standard, statistical models. Overall, these models perform well, foreseeing the unprecedented outcome of a “hung parliament”, as most pollsters and pundits did not. Moreover, they achieved this accuracy with forecasts well in advance of the election itself. 相似文献

Derrick Bell’s work challenges the dichotomy that separates legitimate legal reasoning from “mere” fiction through hybrids
that play across science fiction, Platonic dialogue, and autobiography. Despite its merits, I argue that Bell’s position reifies
and strengthens, rather than deconstructs, structures of tyranny; it maintains the problematic rhetorical construction of
United States race relations in terms of the black–white divide, either alienating, or leaving little or no room for other
racial groups constructively to revise power and identity. In contrast, bell hooks’, Mari Matsuda’s and Robert Chang’s work,
though tentatively sketched, construes current race and gender relations in terms of a chiaroscuro of power, rather than a
simple dichotomy.

To address the challenge of capturing latent fingerprint evidence from metal surfaces, a new method of latent fingerprint enhancement based on electrochromic polymer films has recently been developed. Here, we present a study comparing the development and visualization of nonvisible fingerprints on stainless steel substrates using this electrochromic enhancement approach with three classical methods (dusting, wet powder, and cyanoacrylate fuming). Two variants of the electrochromic enhancement method were utilized with polyaniline and poly(3,4-ethylenedioxythiophene) as the electrochromic materials. Fingerprint samples were taken from different donors (varying in age and gender) and were exposed to different environments for systematically varied periods of time (up to 28 days). The environments represent plausible evidential scenarios: left under ambient conditions, washed with aqueous soap solution, washed with acetone, submerged in water, and maintained at elevated temperature. The electrochromic enhancement procedure frequently outperformed the traditional methods, particularly for samples exposed to more challenging histories. 相似文献

This paper demonstrates a numerical pattern recognition method applied to curvilinear image structures. These structures are extracted from physical cross-sections of cast internal pistol barrel surfaces. Variations in structure arise from gun design and manufacturing method providing a basis for discrimination and identification. Binarised curvilinear land transition images are processed with fast Fourier transform on which principal component analysis is performed. One-way analysis of variance (95% confidence interval) concludes significant differentiation between 11 barrel manufacturers when calculating weighted Euclidean distance between any trio of land transitions and an average land transition for each barrel in the database. The proposed methodology is therefore a promising novel approach for the classification and identification of firearms. 相似文献

Using a sample of 7,260 university employees, we investigate how legitimacy, social and human capital influence the employees’
start-up propensity. We find that scientific legitimacy, as measured by the number of recently published peer reviewed scientific
articles, and conference papers accepted had no significant effect. Scientific legitimacy measured as publications in non-peer
review journals even had a negative effect. Popular legitimacy showed mixed results. Measured as number of articles in popular
science publications showed positive correlations and other public media appearances had a non significant effect on start-up
propensity. Individuals who are older and have higher level of human capital, measured as level of education are less likely
to start firms. We also found that, people with more social capital, such as contact with external product development teams
are more likely to start new firms. Taken together, the findings suggest that activities spanning the university-business
divide increase the start-up propensity, while within university activities had no, or negative effects on the propensity.
Consequently, universities interested in encouraging their employees to start firms should focus their attention on creating
spanning activities rather than improving conditions for within university tenure. 相似文献

The utilization of 3D computerized systems has allowed more effective procedures for forensic facial reconstruction. Three 3D computerized facial reconstructions were produced using skull models from live adult Korean subjects to assess facial morphology prediction accuracy. The 3D skeletal and facial data were recorded from the subjects in an upright position using a cone-beam CT scanner. Shell-to-shell deviation maps were created using 3D surface comparison software, and the deviation errors between the reconstructed and target faces were measured. Results showed that 54%, 65%, and 77% of the three facial reconstruction surfaces had <2.5 mm of error when compared to the relevant target face. The average error for each reconstruction was -0.46 mm (SD = 2.81) for A, -0.31 mm (SD = 2.40) for B, and -0.49 mm (SD = 2.16) for C. The facial features of the reconstructions demonstrated good levels of accuracy compared to the target faces. 相似文献

This article reports on a systematic review of English language, peer-reviewed publications from 13 empirical studies with donor-conceived children and adults regarding their experiences and perceptions of donor conception. A total of 19 articles that met the inclusion criteria were reviewed. These were identified by means of a bibliographic search of four electronic databases for the period 1990-2011 and supplemented by the authors' personal knowledge of work in this field. No reports from such studies appeared prior to 2000, and more than half have been published since 2008, demonstrating the relative novelty of research in this field. Much of the reviewed research evidence concerns individuals conceived through sperm donation conducted under a regime promoting both anonymity and nondisclosure. Consequently, there is little research that pertains to individuals conceived through other forms of collaborative reproduction, nor to those conceived under arrangements and regimes in which early parental disclosure is both advocated and practised and the identity of the donor and of other genetic relatives may be accessible to donor-conceived individuals. The studies consistently report that most donor-conceived people have an interest in securing information about their genetic and biographical heritage - more information than most of them have been able to obtain. Although a number of methodological limitations in the research base are identified, the authors conclude that the evidence is sufficiently robust to promote the implementation of policies and practices that promote transparency and openness in collaborative reproduction, thus reflecting the importance of maximising future choices and opportunities for donor-conceived people. 相似文献

An exploratory, qualitative examination of homeless, recovering alcoholic men in a Twelve-Step program shows the ways these
men adapt tools of sobriety to match their needs. Using semi-structured interviews, the experiences of these men were evaluated
in order to find out how they stay sober without a formal place to live. Based on the narrative histories, three varieties
of adaptations to the conventional Alcoholics Anonymous program are discussed: excessive twelfth-stepping, a mélange of religious
principles, and unrealistic ideals. Implications for treatment and directions for future research are discussed. 相似文献
