Two discreet choice experiments investigated how three styles of leadership (i.e., transformational, transactional, and ethical) and three job features aimed at activating different motivational forces (i.e., public service motivation, external regulation, and intrinsic motivation) simultaneously and independently affected the job preferences of a sample of public employees. Subjects displayed a strong preference for jobs that benefit more citizens, that are more interesting, and that require working under ethical leaders rather than unethical ones. Whereas the prospect of a 5% salary increase strengthened participants’ preferences for a given position, offering a 1% salary raise did not significantly change subjects’ job choices. Furthermore, participants did not appear to have any preference for working under a transformational leader rather than a transactional leader. 相似文献

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

Since 15 May 2011 Spain has progressively entered a political and regime crisis in which the main institutional pillars of the political system constructed in 1977-1978 during the transition from the Franco dictatorship to parliamentary democracy suffered from serious wear. This can be analysed following Gramsci's notion of hegemony crisis whose main features fit well with the current situation in Spain. The regime crisis has passed through different stages – the last being the emergence and rise in the polls of Podemos, which emerged in a context marked by the deepening of the crisis and the difficulty of securing significant social victories. To understand the meaning of this current regime crises it is useful to read history, following Walter Benjamin as an open process full of bifurcations with no linear trajectory. Spanish regime crisis opens for the first time since the seventies the possibility of a social and political change whose final sense is still uncertain. 相似文献

Information campaigns are key elements of elections. Past research has established the importance of campaigns in informing and educating citizens, and ultimately strengthening participatory democracy. While the Internet has increased the possibilities to disseminate information campaigns and eased access to political information, it is still debated whether online campaigns are effective in stimulating political interest and participation among the general public. The issue is not only one of access, but also of use of information. The investigation of main effects of campaigns obscures the fact that citizens may not use information in the same way and reap the same political benefits. In this study, I examine the conditional effects of a new type of Web information campaign, Voting Advice Applications (VAAs), on the political engagement and electoral participation of citizens with varying levels of education. By investigating who benefits most from using these apps, I evaluate whether VAAs reinforce patterns of participation or mobilize new people in politics. Building on political behavior research, communication theory, and social psychology, I study the differential effects of VAAs with an innovative randomized field experiment design. The results confirm that VAAs can stimulate the political engagement of the public. However, there is no significant impact on electoral participation. In addition, the evidence shows that VAAs work differently for more or less educated citizens, and that the lower educated users benefit the most from VAAs as they become more interested in the election and more motivated to vote. 相似文献

Right-wing populist parties portray immigrants as economic or symbolic threats in their political advertisements by constructing a moral divide between the “good” ordinary people and “bad” immigrants. Yet, it remains unclear how these different threat appeals contribute to the formation of anti-immigrant attitudes among citizens and what role visual elements play in producing these effects. A survey-experiment with a quota sample of 471 participants reveals that, overall, symbolic threat appeals exert stronger effects on anti-immigrant attitudes than economic ones. When presented via text alone, only symbolic—not economic—threat appeals increased anti-immigrant attitudes via the activation of heuristic processing such as the reliance on negative stereotypes or feelings of anxiety, in particular among lower-educated citizens. When visuals were present, both types of threat appeals enhanced anti-immigrant attitudes among citizens across all education levels based on heuristic processing. Additionally, high image-text congruency induced cognitive argument approval resulting in higher anti-immigrant attitudes. 相似文献

AbstractAs a market tool, microcredit is expected to promote individual freedom, for women in particular. By drawing on a southern Indian case, this paper argues that microcredit is in fact shaped by the power structures it is supposed to eradicate. Even if they are partly reshaped, local structures of power remain unavoidable to protect populations (something that microcredit fails to do) but also to build the microcredit market and ensure its legitimacy, for donors, local political arenas and local populations. Far beyond microcredit, our findings question the uneasy relationships between markets and individual freedoms. 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
