This paper suggests that smallholder farmers in sub-Saharan Africa (SSA) are well placed to seize the opportunities from expanding global and regional demand for agricultural products but that this will require a shift from extensive to more intensive production systems. The ability of SSA's smallholder farmers to increase on-farm investments in productivity is, however, constrained by their capacity to manage the risk-return trade-offs in moving towards intensified agriculture. While stakeholders are increasing their investments to assist smallholders in SSA to participate in integrated supply chains, the returns in terms of technical and financial results from these investments are generally lower than in other developing regions. This paper suggests that this is, at least in part, a consequence of problems associated with the role of spatial and temporal coordination in program delivery. Hence, much more focus needs to be devoted to delivering goods and services for smallholders at the right place and the right time, and this should be better monitored and evaluated in the context of development programs. 相似文献

Abstract Few previous studies have explored the characteristics and dynamics of adolescent sibling incest. The objectives of this paper were twofold: first, to conduct a literature review that accounts for earlier research in the area, and secondly, to conduct a clinical study to explore differences regarding the characteristics of a group of adolescent sibling incest offenders (n=21) compared to a group of adolescent non-sibling offenders (n=24). Comparisons were made regarding variables such as family dysfunction, the offenders' prior victimization and offending behaviour. The data were derived from intake assessment files and semi-structured interviews with 45 adolescents who had sexually offended. The sibling incest offender group had grown up more often in dysfunctional families. Moreover, the results indicated that the offending behaviour in the sibling incest group was more severe. The study gives some empirical support for the possibility that sibling incest can be one sign, among others, of maltreatment during childhood. 相似文献

Why do certain ministers remain in their post for years while others have their time in office cut short? Drawing on the broader literature on portfolio allocation, this article argues that the saliency of individual portfolios shapes ministerial turnover. The main argument is that ministerial dismissals are less likely to occur the higher the saliency attributed to the ministerial portfolio since ministers appointed to important posts are more likely to have been through extensive screening before appointment. Importantly, it is also posited in the article that the effect of portfolio salience is conditioned by government approval ratings: when government ratings are on the decline, prime ministers are less likely to reshuffle or fire important ministers than when approval ratings are improving. To test these claims, Cox proportional hazards models are applied to a new dataset on ministerial turnover in Scandinavia during the postwar period. The results strongly support the proposition that portfolio saliency matters for ministerial survival, and that this effect is moderated by government popularity. 相似文献

The relationship between Western intelligence officials and Nazi war crimes prosecutors has been, and in some aspects remains, a difficult one. It is increasingly apparent that it is precisely the selective nature of support war crimes prosecutors can expect from intelligence officials that merits particular scholarly attention. One such example in this case of positive assistance concerns the provision of a specific piece of evidence, the diaries of Ciano, Mussolini's Foreign Minister, obtained for the Allies by Allen Dulles, a senior US wartime intelligence official with the OSS, based in Bern, Switzerland, and used in the prosecution case against Ribbentrop at the Nuremberg war crimes trials. This article, based largely upon recently declassified American security files, closely examines Dulles' actions undertaken to retrieve the diaries and pass them to the prosecution. 相似文献

This study addresses the dynamics of the issue space in multiparty systems by examining to what extent, and under what conditions, parties respond to the issue ownership of other parties on the green issue. To understand why some issues become part and parcel of the political agenda in multiparty systems, it is crucial not only to examine the strategies of issue entrepreneurs, but also the responses of other parties. It is argued that the extent to which other parties respond to, rather than ignore, the issue mobilisation of green parties depends on two factors: how much of an electoral threat the green party poses to a specific party; and the extent to which the political and economic context makes the green issue a potential vote winner. To analyse the evolution of the green issue, a time‐series cross‐section analysis is conducted using data from the Comparative Manifestos Project for 19 West European countries from 1980–2010. The findings have important implications for understanding issue evolution in multiparty systems and how and why the dynamics of party competition on the green issue vary across time and space. 相似文献

In this paper, I analyse the rehearsals of a choir and focus on sequences during which participants correct and practise the pronunciation of an item. In order to sing in a choir, singers orient both to musical relevancies (such as melody, pitch and rhythm) and to the linguistic features of the words they sing (such as articulation of consonants or vowels, cutting of the syllables, accent): these features are fundamental to singing and can be the object of correction. I hereby take into consideration “second language” singing and show that, during this activity, the correction of a word pronunciation can be initiated and realised either by the director or by the singers themselves. I analyse the structure of these sequences and show their implication for the organisation of the activity and for the participatory dynamics of the rehearsals. Based on the video-recordings of the rehearsals of the choir of a music school, my analyses take into account both the audible and visible resources participants orient to; they thus contribute to a conversation analytical and multimodal perspective on the interactional and institutional activity of music rehearsals. 相似文献
