South Asia remains one of the major strongholds of hunger in the world, despite the fact that, following the Green Revolution, cereal production in the countries of this region tripled during the second half of the 20th century. This study examines the role played by this increase in cereal production in improving the region’s nutrition and food security situation. We study the association between the different aspects of food security and cereal production in South Asia that have prevailed over the past 25 years. We find a beneficial role of the production and yield of cereals in lowering the extent of undernourishment. A 1% increase in cereal production and yield is associated with up to 0.84% decrease in the prevalence of undernourishment. The impact is significant over a period of 3 years. The positive effect is particularly evident in the case of rice and maize production. An improvement is seen in the aspects of availability, stability, and utilization of food security but not in the aspect of access. These findings are robust to alternative specifications and techniques. The results explain, in part, the means by which South Asian nations have managed to stall relative increases in extreme hunger and food insecurity.  相似文献

This paper questions the impact of the globalization of the retail sector on the export activity of origin country agri‐food firms. We use an original firm‐level database of French agri‐food exports that identifies the domestic suppliers of French retailers through certification with the private International Featured Standard (IFS). The results show that IFS certified French firms are more likely to export and export larger volumes than noncertified firms to markets where French retailers have established outlets. We also show that when French retailers stop their activities in a market, certified firms reduce their exports to this market in the following years. The results are robust to the use of different sets of firm‐year‐ and country‐year‐specific controls and fixed effects, and are not affected by possible selection and endogeneity biases. The difference in the behavior of certified and noncertified exporting firms on markets where French retailers operate confirms the network effect that benefits retailers’ suppliers, which is lost when French retailers exit from the destination country.  相似文献

This paper explores the time variation in the stock–bond correlation using high-frequency data. Gradual transitions between regimes of negative and positive stock–bond correlation are well accommodated by the smooth transition regression (STR) model. We find that the regimes are systematically related to movements in financial and to a minor extent macroeconomic transition variables. In particular, the most informative transition variables are the short rate, the yield spread, and the VIX volatility index. Importantly, both in-sample and out-of-sample evaluation criteria show that multiple transition variable STR specifications considerably outperform single transition variable STR models. Our results are robust to different forecast horizons.  相似文献

While rapid changes in the treatment of cancer have been driven by research-based evidence, innovations in cancer care delivery have lagged behind that seen in cancer treatment. A literature review and ten semi-structured interviews were conducted to identify models of care in the ambulatory oncology setting to be adopted by a comprehensive cancer center. Four models were identified from the literature review but none were widely recognized or adopted by administrators. Findings suggested some common themes that should be included in an optimal model of care. These themes are in support of the burgeoning efforts seen in the promotion of interprofessional education and practice for quality improvement. Unique challenges related to the contextual factors in the ambulatory oncology settings suggest quality improvement interventions should be tailored to meet the specific needs of the care facility and its workforce.  相似文献

Kawasaki disease     
Kawasaki disease is currently the leading cause of acquired heart disease in children in the United States and Japan. The case of an 18-year-old insurance applicant is used to review the pathogenesis, complications, treatment and prognostic implications of this disorder.  相似文献

In a post-constitutional context, restructuring of constitutional rights often fundamentally alters the role and scope of government. It is therefore important to assess the extent to which consensuality is likely to characterize the process of constitutional revision. This article provides theoretical and empirical grounds for concluding that nonconsensual constitutional revision is often the rule rather than the exception. The endogeneity of politically relevant transaction costs and their manipulation by self-interested political actors in a post-constitutional environment are central to the analysis. I wish to thank Robert Higgs and this journal's referee for helpful comments on an earlier draft.  相似文献

A bstract . Although a strong legal basis now exists for equal opportunity in employment for women , women's earnings have actually dropped relative to men's. This holds true even when experience on the job , life-time work experience , and education are similar. Females are also still twice as likely as males to be below the poverty line. The impact of low female earnings may be of even greater significance today because of the increase in female-headed families. Equal opportunity legislation has not been sufficient to end economic sexism.  相似文献

On the basis of interview materials, this article describes the organizational and attitudinal barriers Japanese women face in respect to recruitment and career mobility in Japanese corporations and the career implications of their roles as wives and mothers. Forces for change in the position of white-collar and managerial women are also examined, with particular reference to the internationalization of the Japanese economy and society.  相似文献

ABSTRACT

Comparative cross-national research permits scholars to understand how strategic communication is impacted by environmental conditions in different countries. Although the field has burgeoned enormously over the past two decades, there has been little discussion about what comprises an excellent comparative study, and little is known about the state-of-the-art of comparative research in the field of strategic communication. This article suggests a set of general scientific criteria for solid comparative research and applies these to assess the quality of comparative studies in strategic communication. Based on an analysis of 75 studies located through a systematic search in 16 journals, this article sketches the contours of a fast-emerging research field, which is increasingly driven by European and Asian scholars. The results identify common deficiencies and indicate that the potential of comparative research to contextualize and explain strategic communication in different countries has not yet been fully exploited. Future directions for engaging in more advanced comparative strategic communication research are given.  相似文献

This article explores policy approaches to educating populations for potential critical infrastructure collapse in five different countries: the UK, the US, Germany, Japan and New Zealand. ‘Critical infrastructure’ is not always easy to define, and indeed is defined slightly differently across countries – it includes entities vital to life, such as utilities (water, energy), transportation systems and communications, and may also include social and cultural infrastructure. The article is a mapping exercise of different approaches to critical infrastructure protection and preparedness education by the five countries. The exercise facilitates a comparison of the countries and enables us to identify distinctive characteristics of each country’s approach. We argue that contrary to what most scholars of security have argued, these national approaches diverge greatly, suggesting that they are shaped more by internal politics and culture than by global approaches.  相似文献
