A vector autoregression is fit to recent U.S. data on wheat prices, wheat export sales, wheat export shipments, and exchange rates. Forecast error decompositions and out-of-sample forecasts indicate that exchange rates have little influence on wheat sales and shipments. 相似文献

This article has two objectives. First, it aims to complement and extend existing research on post-socialist demographic change, which has thus far tended to focus on Central and Eastern Europe. It does this by describing the nature of post-Soviet trends in nuptiality and fertility in Tajikistan, the republic with the highest rate of population growth during the Soviet period. It finds evidence for a decrease in period fertility after independence: initially, through a decline at higher orders; then, through a significant decrease in the rate of first births, associated with a dramatic decrease in the rate of first union formation since the mid-1990s. Second, it aims to contribute to the demography of conflict and of food crisis. Most clearly, it finds strong evidence for a decrease in nuptiality and fertility associated with the 1995 food crisis. 相似文献

This article focuses on the pattern and impact of change leadership in complex, pluralistic, public sector settings, and specifically in English healthcare. The argument draws on evidence from ten comparative cases, exploring links between leadership patterns and organizational outcomes. Our analysis builds three themes. First, a pattern of widely distributed change leadership is linked to delivering improvements in service outcomes. Second, professional/managerial hybrids are shown to perform crucial lateral facilitation activities, adapting and extending their roles to suit their organizational context. Third, a foundation of good pre-existing relationships underpins the capacity of distributed leadership to implement service improvements. Conversely, poor relationships and conflicts erode the concerted capacity of distributed change leadership. The key contribution of this article thus concerns the establishment of links between situated patterns of distributed leadership, and service improvement outcomes, based on the cumulative effects of actors – managers and clinical hybrids – at different organizational levels. 相似文献

Patagonia in the late nineteenth century was a frontier region of Argentina, contested both by the indigenous people and by the neighbouring Chilean republic. After brutal repression of the Patagonians by the Argentine military forces, the area was opened up for colonial settlement. The Argentine authorities recognised Afrikaners as suitable recruits for colonial settlement and, starting in 1902, groups of settlers made their way to South America. Many explanations for this migration have seen its cause in the defeat of the Boer republics. While these explanations are partly justified, the majority of emigrants were dispossessed Cape landowners and tenant farmers, who chose to move to Patagonia to avoid proletarianisation in the South African mining towns. However, the Afrikaner community in Argentina did not flourish, and was finally broken by the economic depression that started in 1929. With the resurgence of right‐wing nationalism amongst Afrikaners in South Africa in the 1930s, moves to repatriate surviving South American families gained momentum. Of the few who remained in Patagonia, links with South Africa were virtually erased by cultural assimilation. 相似文献

Abstract Objective: Data about college student sleep were collected and used to develop an education campaign to improve sleep. Participants: On-campus residents at a large state university were surveyed on 4 occasions, October 2005 to April 2007. Sample size was 675 to 1,823 students. Fall 2005 mean age = 18.5 years, SD = 1.03 (range 18–30) years. Initial survey included 935 males and 1,859 females (2005–2006). Matched pairs data (2006–2007) included 91 males and 107 females. Twenty-six males and 22 females participated in interviews. Methods: A survey administered online included the Pittsburgh Sleep Quality Index, along with an 8-question in-person interview. Results: Poor sleep interacted with academics and mental health, and an education campaign positively affected student sleep. Conclusions: Teaching students how to effectively manage sleep can improve their well-being. Sleep may also be a gateway topic for health care professionals to address sensitive health issues such as depression. 相似文献
