Inverse Productivity or Inverse Efficiency? Evidence from Mexico 总被引:2,自引:0,他引:2
Using a unique panel data set from rural Mexico, we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency: large farms not only have a lower value of output per hectare than small farms, they also produce further from the efficiency frontier. Our findings suggest that, in spite of the ongoing transformation of agricultural supply chains and economists’ recommendations for small farmers to exit crop production, there may be sustained advantages for smallholder farms. Our analysis offers new insights into inverse-farm size relationship, the productivity–efficiency relationship, and the use of stochastic frontier techniques. 相似文献

Edward Comor 《国际研究季刊》2001,45(3):389-408
The author examines the concept of global civil society (GCS) through the use of theoretical tools and empirical evidence related to the study of International Communication. He demonstrates that scholarship on GCS tends to simplify the process through which information becomes knowledge and that the state system–GCS relationship often is presented in terms of an ahistorical power dichotomy. In relation to these problems, what the author calls GCS progressives tend to underplay political-economic factors shaping GCS, including the implications of structural power; they tend to emphasize the importance of spatial integration while neglecting related changes in temporal norms; and, more essentially, they often under-theorize the importance of socialization processes and relatively unmediated relationships in the ongoing construction of reality. The author concludes that through a more focused analysis—concentrating on how new technologies can be used to organize nationally and locally, and on lifestyle changes associated with communications developments—more precise analyses and fruitful strategies for GCS progressives may emerge. 相似文献

This study interviewed 350 African immigrants in North Carolina (NC) to shed light on their economic conditions. It focused primarily on their labor force participation and incomes for the period 2004–2014. The findings showed that both structural changes in NC's economy and prejudicial experiences within the labor force were the most important forces that undermined the economic ambitions of the Africans. The study also yielded a complex picture and raised some questions about the resettlement outcome of African immigrants in the United States. 相似文献

The Srebrenica massacre has taken on both symbolic and mythical properties, all in the service of political agendas. The symbol is of Serb evil, manifested in an alleged cold-blooded and unprovoked massacre of innocents reminiscent of Nazi behavior during World War II. The myth is that 8000 Bosnian Muslim “men and boys” were executed in the vicinity of Srebrenica in July 1995, and that any executions there were unprovoked and carried out in accord with a genocidal plan. Both facts and language have had to be aggressively massaged to support these claims. The political agendas served by the massacre claims were those of the Bosnian Muslims, striving to get NATO to enter the Bosnian struggle more actively, the Croats, who needed a demonization of Serbs to carry out their own ethnic cleansing plans (most notably, removing 250,000 Serbs from Croatian Krajina in the very next month, August 1995), and the Clinton administration, under attack for a failure to intervene more actively on behalf of the Croats and Muslims and searching for an excuse to do so.This paper is partly drawn from and cites chapters in a forthcoming book on the Srebrenica massacre, Srebrenica: The Politics of War Crimes, written by George Bogdanich, Tim Fenton, Philip Hammond, Edward S. Herman, Michael Mandel, Jonathan Rooper, and George Szamuely. This book is referred to in the notes below as Politics of War Crimes. The author and his colleagues are indebted to Diana Johnstone, David Peterson, Vera Vratusa-Zunjic, Milan Bulajic, Milivoje Ivanisevic, Konstantin Kilibarda, and George Pumphrey for advice. Johnstone’s Fools Crusade is a fine basic statement of an alternative perspective on the Balkan Wars; George Pumphrey’s “Srebrenica: Three Years Later, And Still Searching,” is a classic critique of the establishment Srebrenica massacre narrative and repeatedly hit the target with facts and analyses still not rebutted. 相似文献

In the 1990s methamphetamine (meth) emerged as a significant drug problem in the United States. Along with more widespread meth use was a growing pattern of localized production of the drug in small-scale clandestine laboratories, creating public health issues beyond the drug’s direct harms to the health of users. Early efforts in analyzing aggregate patterns of meth lab production across communities suggest this phenomenon is different from other types of crime and drug problems, showing distinctive geographic patterns and different causal/etiological dynamics. This paper assesses the viability of public health outcomes as predictors of methamphetamine laboratory problems and compares them with traditional criminological predictors as explanations for aggregate patterns in meth lab problems across U.S. counties. It documents how local variations in meth production are different from other types of crime patterns and identifies whether geographic variations in local meth labs might be more effectively predicted and explained in public health terms. 相似文献
