Andean farmers have traditionally adapted and selected varieties of quinoa and potatoes to reduce their vulnerability to a range of environmental risks. Data suggest that this strategy is being undermined. Market pressures, particularly the requirements for consistency and quantity along with the import of subsidised wheat products, are leading to the displacement of quinoa and indigenous potato varieties. This paper explores the feasibility of maintaining crop diversity while ensuring that farmers benefit from market opportunities. For potato, the most promising approach is one of ‘conservation through use’, whereby development practitioners identify market niches for local rather than cosmopolitan varieties. Meanwhile, quinoa production and consumption has been enhanced by government-sponsored initiatives that use quinoa in food-support programmes. The success of these efforts to enhance livelihood security requires an enabling policy environment that encourages extension approaches, where the emphasis is on farmers' active participation, and supports public and private interventions in remote rural areas.  相似文献

Past research has revealed conflicting findings regarding the degree to which judges on European apex courts enact their policy preferences or instead disagree on the basis of divergent legal views. We investigate disagreement between judges on the Norwegian Supreme Court between 1996 and 2016. During this period, the court dealt with a greater volume of policy-relevant cases than previously. The method of appointment to the court was also changed to a judicial appointments commission. We analyse non-unanimous cases using item response theory models. We find that judges are not divided along left–right lines but instead disagree about the appropriate degree of deference to give to public authorities. There is no significant association between the appointing government and judges' ideal points either before or after the reform to appointments. Judges who were formerly academics are however much less deferential than career judges or judges who were previously lawyers in private practice.  相似文献

Research suggests that among college students, physical and sexual abuse in intimate relationships are associated with posttraumatic stress. Psychological abuse occurs in intimate relationships among college students, and though there is evidence that such abuse has a negative emotional impact, posttraumatic stress has not been extensively researched as an outcome in this population. The purpose of this study is to determine the associations of past-year psychological abuse with posttraumatic stress symptoms while controlling for other types of past-year relationship abuse and lifetime trauma history. The sample consists of 191 college men and women (81.7% women and 89.5% White). Linear regression analyses demonstrate that trauma history, but not past year relationship violence, is a significant predictor of PTSD symptom severity for women, and neither set of variables significantly predicts PTSD symptom severity for men. Implications for future research are discussed.  相似文献

Objective

The current study sought to illuminate the patterns associated with serious inmate-on-staff assaults, as well as the characteristics of perpetrators and victims.

Material and methods

This study examined 79 assaults on prison staff requiring more than first aid treatment, perpetrated by 96 inmates, in a large state correctional department during a 14-month period (September 1, 2007 through October 31, 2008).

Results

These assaults were both infrequent (53 per 100,000 inmates annually) and progressively more infrequent as the severity increased (hospitalization for non-life threatening injury or required reconstructive surgery = 2.2 per 100,000 inmates annually; hospitalization for life-threatening injury = 0.5 per 100,000 inmates annually). Among staff victims, Black and female correctional officers were underrepresented. Inmate perpetrators who were younger, Black, prison gang members, and/or serving sentences for violent offenses were disproportionately represented among assailants.

Conclusions

The low overall rate of serious staff assaults attests to the level of professionalism and training in modern corrections departments. Nonetheless, situational factors uncovered in the current analysis suggest that particular circumstances increase the likelihood of staff assaults, hence the need for continued training and vigilance on the part of correctional staff that come in direct contact with inmates.  相似文献

This study examines the impact organizational stressors have on police performance. Evidence on police stress is mixed whether or not the nature of police work is inherently stressful. A growing body of research suggests police officers are no more stressed than other groups and police work is not especially stressful. Instead, organizational stressors may be a greater source of stress due to various structural arrangements, policies and practices. This cross-sectional study uses survey data (n = 461) from two large urban police departments in Michigan and New Jersey. Multiple regression predicts lower performance as perceived stressors increase and paired-sample t test reveals organizational stressors are significantly different from operational stressors. The results imply the need for structural changes in police organizations. Future research should examine police performance in smaller and mid-size police agencies as well as suburban and rural agencies and widen the participant pool to include superior officers and civilian personnel.  相似文献

How do electoral institutions affect legislative behavior? Though a large body of theoretical scholarship posits a negative relationship between multimember districting and the provision of particularistic goods, empirical scholarship has found little evidence in support of this expectation. Using data on the provision of US post offices from 1876 to 1896, a period during which many states elected congressional representatives from at‐large districts, and a differences‐in‐differences approach, I find that counties represented by at‐large representatives received approximately 8% fewer post offices. The results have important implications for studying how electoral institutions affect incentives for legislative behavior.  相似文献
