Indigenous vegetables play an important role in Kenyan food security, but production is limited by poor seed quality. Traditionally, seeds have been traded through informal networks, but a new formal seed sector is emerging. This study assessed the relative potential for formal or informal seed systems to meet the need for high-quality indigenous vegetable seed. By evaluating determinants of farmers’ seed purchasing behaviour, we conclude that informal seed systems have greater potential to meet this need and should be strengthened. This study suggests that policy-makers should use context-specific data to guide decisions on seed policy. 相似文献

Among local governments, inter-municipal cooperation is the growing reform; but the literature is silent regarding the determinants of longer-term shared service agreements. We conducted a survey of all local governments in New York State in 2013 to assess the level of sharing across 29 public services. The duration of shared service agreements varies from 1 to 80 years. What explains this difference? Our hierarchical linear model shows that service sharing agreements fall along a cooperation continuum, where cost savings are a determinant of shorter agreements, while the public values of service quality and cross-jurisdictional coordination explain longer-term agreements. We also find that positive past experience with sharing partners increases the duration of sharing agreements. Our analysis lays the foundation for new theories of shared services that build directly from the benefits of improved regional coordination, inter-municipal reciprocity and service quality, not from theories based solely on competition and costs. 相似文献

This paper explores how remittances influence happiness among migrants and their households of origin. It is based on a novel data set of matched samples of Bangladeshi migrant households (living in the UK and Malaysia) and their origin families in Bangladesh. Empirical findings suggest that remittances play a significant role in stimulating migrants’ happiness. We also find that the households of origin’s life satisfaction not only depends on receiving remittances from the emigrants, but also other factors such as number of migrants from the household living abroad and the migrants’ country of destination. 相似文献

During the last decade, several formalized approaches have been developed to improve the effectiveness of probation and parole by implementing evidence-based research into community supervision practices. A key component of these new approaches are the use of officer coaching sessions, which are designed to improve officer fidelity in the core correctional skill areas. This study explores the impact of an initial training and monthly coaching sessions in the Effective Practices in Community Supervision (EPICS) model on probation and parole officer use of core correctional skills. The results examine the average quarterly officer use of skills over an 18-month follow-up period based on training status (i.e., trained versus untrained officers) in the EPICS model. This study adds to the understanding of the role training and coaching may play in improving officer use of core correctional skills. Policy implications and recommendations for future research are also discussed. 相似文献

The new reproductive technologies have made possible various postmodern family forms. I highlight an emerging form that has received little attention: single fathers by choice (SFCs), created by single men using egg donation and surrogacy. I focus on heterosexual SFCs, which have been largely ignored in the scholarly literature even as gay and lesbian parenthood have increasingly become topics of feminist inquiry. This type of fatherhood raises several important questions for gender and family scholars about the ‘traditional’ family, the relationship between masculinity and fatherhood, and men’s own desires for parenthood without a female partner. I analyze US media framing to explore cultural sense-making of SFCs. While media framing cannot tell us about men’s lived experiences as intentional single fathers, it does point to larger discourses that potentially impact these men as they engage in non-normative fathering. I identify three core themes within the media frames: (1) viewing men and women as similar, but ultimately different, (2) addressing the tension between bachelorhood and fatherhood, and (3) representing the gender of paternal desire in multiple, conflicting ways. Overall, I argue that further investigations of SFCs can illuminate issues about men’s desires for children and agency in becoming fathers. 相似文献

Early alcohol use is associated with multiple negative outcomes later in life, including substance use disorders. Identification of factors related to this very early risk indicator can help inform early prevention efforts. This study prospectively examined the relationship between childhood adversities and early initiation of alcohol use (by age 14) among Puerto Rican youth, the Latino subgroup at highest risk for alcohol use disorders in adulthood. The data come from the Boricua Youth Study, a longitudinal study of Puerto Rican youth in two sites (South Bronx, New York, and the standard metropolitan area of San Juan, Puerto Rico). We focus on youth who were ages 10 and older at Wave 1 [M age at Wave 1 (SE)?=?11.64(0.05), N?=?1259, 48.85?% females]. Twelve childhood adversities were measured at Wave 1 and include 10 adverse childhood experiences commonly studied and two additional ones (exposure to violence and discrimination) that were deemed relevant for this study’s population. Early initiation of alcohol use was determined based on youth report at Waves 1 through 3 (each wave 1 year apart). Cox proportional hazards models showed that, when considered individually, adversities reflecting child maltreatment, parental maladjustment, and sociocultural stressors were related to early initiation of alcohol use. Significant gender interactions were identified for parental emotional problems and exposure to violence, with associations found among girls only. Adversities often co-occurred, and when they were considered jointly, physical and emotional abuse, parental antisocial personality, and exposure to violence had independent associations with early alcohol use, with a stronger influence of exposure to violence in girls compared to boys. The accumulation of adversities, regardless of the specific type of exposure, increased the risk for starting to drink at a young age in a linear way. The associations between childhood adversities and early alcohol use were generally consistent across sociocultural contexts, in spite of differences in the prevalence of exposure to adversity. Our findings highlight the importance of targeting multiple adversities and expanding the notion of adversity to capture the experiences of specific groups more adequately. 相似文献

Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents. 相似文献

Justice-involved youth have high rates of psychiatric diagnoses, and these youth are often placed out-of-home, although evidence identifies several negative implications of juvenile confinement, especially for youth with psychopathology. Furthermore, youth in the justice system may be processed differently based on gender. As males and females tend to manifest symptoms differently, the psychopathology of youth may act to moderate the relationship between gender and placement in the juvenile justice system. The present study used a large, diverse sample (n?=?9?851, 19.8?% female) to examine whether youth placed in various types of out-of-home facilities differed in terms of externalizing, internalizing, substance use, or comorbid disorders, and to determine the predictive value of mental health diagnoses in placement decisions. The moderation effect of psychopathology and substance use on the relationship between gender and placement also was explored. The results indicated that each type of disorder differed across placements, with internalizing being most prevalent in non-secure, and externalizing, comorbid, and substance use being most prevalent in secure settings. Mental health diagnoses improved the prediction of placement in each out-of-home placement beyond legal and demographic factors such that externalizing and substance use disorders decreased the likelihood of placement in non-secure settings, and internalizing, externalizing, and substance use disorders increased the likelihood of placement in secure and state-secure facilities. The relationship between internalizing pathology and placement in more secure facilities was moderated by externalizing pathology. The relationship between gender and placement was significantly moderated by mental health such that females with mental health diagnoses receive less secure placements. Implications for policymakers and practitioners are discussed, as well as implications for reforming juvenile justice within a developmental approach. 相似文献
