The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit/yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using varietal trial data from Washington State. As the private open‐pollinated varieties exist only because of PVP and are higher yielding, these results indicate a clear public benefit from PVP. 相似文献

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant-sensing system to determine winter wheat nitrogen requirements. We find that plant-sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system. 相似文献

Volunteers at music festivals play a critical role in festival operation and success. As the music festival industry continues to grow, the ability for these large productions to effectively execute a large volunteer program is augmented. Volunteers from the 2013 Austin City Limits Music Festival were surveyed in regards to their self-image congruency, motivation, satisfaction, and intent to return as a volunteer at the festival. Analysis resulted in three distinct segments which has significant practical implications for festival management. Academic implications exist with the addition of self-image congruency and further discovery of volunteers in the festival and event industry. 相似文献

The nutrition transition in diets and health is closely tied to other aspects of economic development, including agricultural transformation and urbanization as well as demographic change and epidemiological transition from infectious to noncommunicable disease. Over time, dietary patterns typically shift from widespread inadequacy of many foods and nutrients, especially for children and mothers, into surplus energy intake and rising obesity with continued inadequacy of healthier foods. Diet‐related diseases remain the largest single cause of premature death and disability in all regions. This article combines food availability and dietary intake data from more than 100 countries over 30 years with a wide range of other evidence to characterize the nutrition transition and its association with changes in agricultural production and the food environment, asking how future dietary patterns might be steered toward healthier outcomes as national incomes grow. 相似文献

Integration by Emerging Economy Multinationals: Perspectives from Chinese Mergers and Acquisitions

The integration process of international mergers and acquisitions by emerging economy multinationals is fraught with challenges of liabilities of foreignness and country of origin. We use insights from institutional theory and draw on the experience of Chinese international mergers and acquisitions to explore these challenges faced by emerging economy multinationals during postmerger integration. We find that these challenges, which are primarily caused by informal institutional differences, can be overcome by developing organizational capabilities for integration and employing mechanisms for appropriate control and justice during the integration process. The study contributes to the ongoing discussions about the relevance of sociocultural influences in the successful integration of international mergers and acquisitions. Our framework proposes initiatives that managers from emerging economies can take to overcome postmerger integration challenges. © 2016 Wiley Periodicals, Inc. 相似文献

Bundling attractions for rural tourism development 总被引:1,自引:0,他引:1
Wei-Jue Huang J. Adam Beeco Jeffrey C. Hallo William C. Norman 《Journal of Sustainable Tourism》2016,24(10):1387-1402
Tourism is often regarded as a viable solution to economic crisis, especially for remote areas without many development options. While many tourism destinations have strong cultural or heritage assets, not all destinations have primary attractions that can bring visitors to the region. Rather than developing special interest “themes”, rural areas that do not have enough of any one type of tourism resource to act as a primary draw may consider bundling different attraction types to increase visitation. The purpose of this study is to investigate the preferences of visitors to secondary heritage sites and explore the relationship between heritage tourism and alternative, non-heritage activities in rural areas. Findings revealed that motivation to visit small-scale heritage sites consisted of two dimensions: learning and recreation. The two motivational dimensions influenced visitors’ interest in different heritage attractions and likelihood of visiting heritage tourism “scenarios”. As for alternative activities, there was a cluster of “popular” activities that were enjoyed by both learning-oriented and recreation-oriented respondents, but recreation-oriented visitors were more interested in nature-based activities and sport-related activities than learning-oriented visitors. Findings can help rural communities improve secondary attractions and diversify their tourism product by bundling heritage attractions with non-heritage activities. 相似文献

To achieve sustainability in heritage tourism, tourists should be placed at the heart of the management and planning processes. Indicators and standards-based frameworks were developed in the field of outdoor recreation management to manage and measure crowding and other problematic issues in parks and related areas. Using normative theory and visual research methods, this article aims to examine crowding standards of tourists at Petra Archaeological Park, and compare these standards between the types of heritage tourists suggested by a model developed by Bob McKercher. Results showed that tourists’ acceptability levels go down with an increasing number of tourists, and tourists who are highly motivated to visit heritage sites (i.e. purposeful and sightseeing heritage tourists) had the most restrictive acceptable number of tourists at the park. The normative standards formulated in this article provided a guidance to manage crowding at Petra. 相似文献

I agree that Sebastian Mallaby’s detailed and well-sourced The Man Who Knew: The Life and Times of Alan Greenspan, will be essential for every future economic historian studying the Greenspan era. That said, Mallaby does not convey to his readers a sound understanding of monetary policy. I disagree with Mallaby’s claim that Greenspan could and should have done something about the housing and subprime mortgage bubbles. Peter Wallison makes a strong case that the affordable housing quotas did not just “encourage” but forced the GSEs to buy subprime mortgages. Information available in real time on aggregate subprime mortgage issuance was seriously flawed because the GSEs did not report accurately. Greenspan cannot be held responsible for the GSEs hiding the subprime debt on their balance sheets. These mortgages were central to the crisis. It seems improbable that any monetary policy mistake of 2001–05 was large enough to create the crisis. Mallaby could have written a final chapter emphasizing the Maestro resisting the power of a malign and evil pair of GSEs and the power of the President and Congress of the United States pursuing a disastrous housing policy. Despite the Maestro’s best efforts, Leviathan triumphed and brought ruin upon the Nation. 相似文献

The comprehensive business exam: Usefulness for assessing instructional and student performance outcomes 总被引:1,自引:1,他引:0
The authors explore the results of the Comprehensive Business Exam (CBE) administered to business majors during their senior-year business capstone course. The study results identified students' SAT and grade point average as a predictor of CBE performance, and variables that explain the correlation between CBE performance, SAT score, and grade point average are discussed. This study expands the research stream by demonstrating how faculty can use CBE information to more deeply assess student learning at both the course and instructor level than is possible with the Major Field Test for Bachelor's Degree in Business. 相似文献
