This article examines contemporary challenges of formal seed sector participation for resource-poor farmers in Tharaka and engages in a wider discussion of national seed policy and formal seed sector development in Kenya. While many farmers reported utilising modern seed varieties developed by the formal seed sector, the majority of these were introduced through seed aid and maintained through seed saving, supporting seed system integration strategies. Building on these findings, the article discusses ways in which national seed policy in Kenya might be refined to better meet national and regional development goals focused on decreasing the incidence of hunger and poverty.  相似文献

This article reports on the results of exploratory surveys with immigrant women regarding their observations of intimate partner violence and criminal justice practices in their communities in the emerging immigrant gateway of Baltimore, Maryland. Using an intersectional/interlocking theoretical framework, it asks how nativity interacts with other social locations in the experiences of partner violence through surveys of women representing 5 language groups. The study found high levels of awareness of the problem of partner violence in immigrant communities and strong awareness of many U.S. criminal justice approaches to the problem. Although the women preferred informal sources of support in a situation of abuse, they strongly supported government intervention. We found low levels of awareness of the Violence Against Women Act as well as little support for the higher levels of prosecution for batterers, even though arrest was sometimes approved. The article calls for sensitive policies and practices that take into account the particular vulnerabilities of the foreign-born, especially in localities where national diversity is relatively novel.  相似文献

People in prison participating in college education are least likely to recidivate and most likely to be employed after incarceration. Almost no research exists on the collateral – negative and often unanticipated – consequences of a criminal conviction on access to college upon community re-entry. We review these few studies, the existing research on college in prison – with special attention to women’s needs; some new ‘hybrid’ programs with 2 years of college in prison plus 2 years in the community; and the rare studies that interview people applying to college upon re-entry. Their struggles can be overwhelming and require more research and activism.  相似文献

A screening instrument for detecting intimate partner violence (IPV) was developed using indirect questions. The authors identified 5 of 18 items studied that clearly distinguished victims of IPV from a random group of health conference attendees with a sensitivity of 85% and a specificity of 87%. This 5-item instrument (SAFE-T) was then tested on 435 women presenting to three emergency departments and the results compared to a direct question regarding current abuse. The SAFE-T questions detected only 54% of the women who admitted being abused and correctly classified 81% of the women who said they were not victims. The 1-year prevalence of IPV in this sample of women presenting to an emergency department was 11.6%. The authors conclude that indirect questioning of women appears to be more effective at ruling out IPV in an emergency department population and may be less useful for women "early" in an abusive relationship.  相似文献

Purpose. Through an examination of serial rape data, the current article presents arguments supporting the use of receiver operating characteristic (ROC) analysis over traditional methods in addressing challenges that arise when attempting to link serial crimes. Primarily, these arguments centre on the fact that traditional linking methods do not take into account how linking accuracy will vary as a function of the threshold used for determining when two crimes are similar enough to be considered linked. Methods. Considered for analysis were 27 crime scene behaviours exhibited in 126 rapes, which were committed by 42 perpetrators. Similarity scores were derived for every possible crime pair in the sample. These measures of similarity were then subjected to ROC analysis in order to (1) determine threshold‐independent measures of linking accuracy and (2) set appropriate decision thresholds for linking purposes. Results. By providing a measure of linking accuracy that is not biased by threshold placement, the analysis confirmed that it is possible to link crimes at a level that significantly exceeds chance (AUC = .75). The use of ROC analysis also allowed for the identification of decision thresholds that resulted in the desired balance between various linking outcomes (e.g. hits and false alarms). Conclusions. ROC analysis is exclusive in its ability to circumvent the limitations of threshold‐specific results yielded from traditional approaches to linkage analysis. Moreover, results of the current analysis provide a basis for challenging common assumptions underlying the linking task.  相似文献

Increasing gender diversity in American policing has long been a focus of reform efforts since the 1960s. Although the proportion of women in the profession improved initially and research has focused on the gender breakdown of police organizations in general, less scholarly and empirical attention has been directed to female representation in positions of power (i.e., supervisory and management roles). Using data from the 2013 Law Enforcement Management and Administrative Statistics survey, the current study examined the prevalence as well as the organizational correlates of female representation in supervisory (e.g., sergeants), mid-level management (e.g., lieutenants) and chief executive roles in departments across the United States. The findings indicate a number of factors associated with female representation in supervisory and mid-level management positions, including the size and type of agencies, geographic region of the country, and potential indicators of professionalism. Policy implications and directions for future research are discussed.  相似文献
