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

This article discusses citizenship and belonging with reference to processes of post-war state formation, namely: the MPLA’s political hegemony and the centralisation of power in the presidency. It argues this political arrangement imposes upon individuals an oscillation between different ‘levels’ or hierarchies of citizenship with a tendency towards marginalisation, formally allowing them to access both but under the specific circumstances dictated by the MPLA party state. Without a strong political opposition with a plausible alternative citizenship doctrine and with little incentives to improve the terms of citizenship it provides to the population, the Angolan government constructed a system of interests whereby the MPLA functions as a gatekeeper. Both in control of the state and of the distribution of citizenship, the regime regulates the flow of resources to the bottom through strategies of poverty and dependency, which increase the distance between the state and the population and sponsors the marginalisation of the majority.  相似文献

This article assesses the European Union (EU)’s engagement with the Israeli-Palestinian conflict and highlights the unintended consequences of the policies pursued by Brussels on this matter. While stressing that Palestinians and Israelis interested in peace face the danger of the banalization of the conflict, the article argues that the current status quo is unacceptable and unstainable in the long run, and this demands new policies from the actors involved with the conflict or its resolution. The EU policies’ overall rationale must be to treat the Israeli?Palestinian dispute as a normal, non-exceptional conflict, in which economic and legal tools can be employed to create new legal facts on the ground. An alternative EU approach to the conflict must recognize the insufficiency of recent initiatives and should be built upon two pillars: the legalization of the main contending issues and the empowerment of the civil society actors and initiatives that foster dialogue between Palestinians and Israelis.  相似文献

This article analyses the background, content and implications of the EU proposal for ‘Special Privileged Partnership’ status to be granted to Israel and the future state of Palestine in the event of a successful conclusion to the peace process. It employs a sociological institutionalist perspective to assess the diplomatic manoeuvring in the broader context of EU–Israel relations. The analysis offers an identification and categorization of the constitutive components of the EU–Israel relationship into formal and social elements. It argues that differences in threat perception, Israel’s highly securitized ethos and different interpretations of the security versus legality equation are social, constitutive elements of the relationship that cannot be efficiently changed by a mere upgrade of the formal institutional setting, even if the economic incentives to do so were attractive. In other words, the sources of tension between the EU and Israel observed in recent decades are not likely to be overcome by a discursive or institutional upgrade around the concept of partnership.  相似文献

The objective of this study was to determine the prevalence of physical and emotional abuse in Portuguese juvenile dating relationships and to investigate attitudes about these forms of violence. A sample of 4,667 participants, aged 13 to 29 years, completed two questionnaires, one behavioral and one attitudinal. At least one act of abuse perpetrated by a dating partner during the previous year was reported by 25.4% of participants (13.4% reported to have been victims of physical abuse and 19.5% of emotional abuse). Abuse of a partner was reported by 30.6% of participants; at least one act of physical abuse was reported by 18.1% and of emotional abuse by 22.4%. The attitudinal data revealed, however, a general disapproval of violence use. Violence support was higher among males, participants with lower educational and social status and those who had never been involved in a dating relationship. Women reported more acts of partner abuse than males; no gender differences were found regarding self-reported victimization. Both perpetration and victimization were reported more by older students. Although university students tend to report more acts of general and emotional abuse against their partners, students from professional schools are more represented among both perpetrators and victims of physical and severe violence. The best predictors of violence were educational status and attitudes toward partner.  相似文献

This article focuses on the macroeconomic management of large inflows of foreign aid. It investigates the extent to which African countries have coordinated fiscal and macroeconomic responses to aid surges. In practice, we construct a panel dataset to assess the level of aid ‘absorption’ and ‘spending’. This article departs from the recent empirical literature by utilising better measures for aid inflows and by employing cointegration analysis. The empirical short-run results indicate that, on average, Africa's low-income countries have absorbed two-thirds of (grant) aid receipts. This suggests that most of the foreign exchange provided by the aid inflows has been used to finance imports. The other third has been used to build up international reserves, perhaps to protect economies from future external shocks. In the long run, absorption increases but remains below its maximum. Moreover, we also show that aid resources have been fully spent, especially in support of public investment. There is only weak evidence that a share of aid flows have been ‘saved’. Overall, these findings suggest that the macroeconomic management of aid inflows in Africa has been significantly better than often portrayed in comparable exercises. The implication is that African countries will be able to efficiently manage a gradual scaling up in aid resources.  相似文献

Using a data set that covers all Portuguese mainland municipalities for the period 1979–2005, this study performs an empirical analysis of the economic determinants of mayors’ decisions to run for another term in office. The literature on the subject is mainly centered on the United States and, as far as we know, there are no papers addressing the economic factors influencing those choices. Probit panel estimations show that local economic conditions matter more than the national or regional economic environment. The results also confirm that political variables are important and that they influence the likelihood of seeking reelection in much the same way as they affect vote and popularity functions.  相似文献
