Smallholder drip irrigation is widely held as a promising technology for water saving, poverty reduction and food security, despite a dearth of evidence of benefits to farmers, especially in sub-Saharan Africa. In this article, we document three development programmes promoting drip irrigation in Burkina Faso. Using actor network theory and insights from critical development studies, we show that development brokers play a key role in aligning interests, shaping activities and interpreting project outcomes. They are accountable towards each other rather than to farmers. This means that success is interpreted through development agencies lenses and with the intention of continuing involvement in future projects. Small farmers’ interests and uptake of the technology are of secondary importance. 相似文献

Propensity-to-vote (PTV) scores are ever more commonly used in electoral research as a measure of electoral utilities. Yet a growing literature employs them as dependent variable in the voting equation in place of the lower information granted by vote recall questions. However, this choice can be seen as problematic because of the very structure of election survey research. To the extent that voters' PTVs are measured in post-election surveys (as it is often the case) these are likely to result endogenously produced by actual voting behavior in the past election – thus partly undermining the validity of the PTV question which, ideally, should not be related to any specific election. In this paper, we try to disentangle the relationship between short-term political attitudes (leader evaluations, issue proximity, economic assessments) and voters' changing patterns of propensities to vote in both an electoral and a non-electoral context. The latter scenario serves as a means to rule out the potentially contaminating effect of voting choices on voters' PTVs. The data comes from two panel surveys of Italian voters conducted by ITANES in occasion of the 2006 general election, and in 2011 (that is, in a non-electoral year) respectively. 相似文献

The debate on international South – North labour migration tends to focus on the receiving end of migration. This bias obscures a proper understanding of the developmental causes and consequences of migration at the sending end. The reciprocal migration – development relationship is examined through the discussion of seven migration ‘myths’. Because of its profound developmental roots, it is useless to think that migration can be halted or that aid and trade are short-cut ‘solutions’ to immigration. Migrant remittances contribute significantly to development and living conditions in sending countries. Nevertheless, the recent ‘remittance euphoria’ is not justified, because unattractive investment environments and restrictive immigration policies which interrupt circular migration patterns prevent the high development potential of migration from being fully realised. Although specific policies can enhance this potential through facilitating remittance transfers and investments, the key lies in encouraging circular migration. Instead of uselessly and harmfully trying to stop inevitable migration, immigration policies allowing for freer circulation can, besides increasing migration control, enhance the vital contribution of migrants to the development of their home countries. 相似文献

The aim of the study is to present the application of a headspace–gas chromatography–mass spectrometry (HS‐GC‐MS) method for the determination of the carbon monoxide (CO) blood concentration and to compare it with carboxyhemoglobin (HbCO) saturation. In postmortem cases, the HbCO measured by spectrophotometry frequently leads to inaccurate results due to inadequate samples or analyses. The true role of CO intoxication in the death of a person could be misclassified. The estimation of HbCO from HS‐GC‐MS CO measurements provides helpful information by determining the total CO levels (CO linked to hemoglobin (HbCO) and CO dissociated from hemoglobin). The CO concentrations were converted in HbCO saturation levels to define cutoff blood CO values. CO limits were defined as less than 1 μmol/mL for living persons, less than 1.5 μmol/mL for dead persons without CO exposure, and greater than 3 μmol/mL for dead persons with clear CO poisoning. 相似文献

This article examined the differential role of self-rumination and self-reflection on the psychological influence of procedural fairness. Study 1 induced self-rumination and self-reflection relative to an outward-focused control. Self-rumination increased the perceived importance of procedural fairness, whereas self-reflection decreased it. Study 2, assessing individual differences in self-rumination and self-reflection, showed that a standard procedural fairness manipulation (voice vs. no voice) predicted future interaction preferences with the enactment source among those high (but not low) in self-rumination and among those low (but not high) in self-reflection. The findings validate a multiple process approach to understanding the role of the self in procedural fairness. 相似文献

In June 2009, the Commonwealth Attorney General in Australia announced a Family Relationship Centres/ Legal Assistance Partnerships Program, (the “Better Partnerships” program). Its aim was to assist separated or separating families, “by providing access to early and targeted legal information and advice when attending Family Relationship Centres” (McClelland, 2009). After contextualizing this significant shift in policy and practice, the present paper reports on largely positive key results of an evaluation of the program by the Australian Institute of Family Studies. The paper concludes with reflections on future challenges and possibilities regarding ongoing collaboration between Australia's legal and family relationship sectors. 相似文献
