Consumer Acceptance And Willingness To Pay For Genetically Modified Rice In China: A Double Bounded Dichotomous Choic Contingent Valuation Survey Calibrated By Cheap Talk, Jing Jin
Graduate Theses and Dissertations
Considering population growth, limitations on land and water resources, and contamination to the ecosystem due to agricultural activities, current rice production in China is facing pressure to fulfill national demand. Self-sufficiency of rice has been a long-held political objective of the Chinese government and it is national goal to maintain the equilibrium between the national production and consumption or even achieve a supply surplus in rice. With the developing bio-technology of genetic modification (GM), scientists believe that using genetically modified cultivars may ease the pressure mentioned above. However, both the government and the people are very cautious about large-scale cultivation …
European Consumers' Attitudes Towards Cisgenic Rice, Anne-Cécile Delwaide
European Consumers' Attitudes Towards Cisgenic Rice, Anne-Cécile Delwaide
Graduate Theses and Dissertations
The enhancement of existing plant breeding techniques, such as cisgenesis, allows plant breeders to enhance an existing cultivar quicker and with little to no genetic drag. Cisgenesis is the genetic modification of a recipient plant with natural gene(s) from a sexually compatible plant. Unlike transgenesis, which is the genetic modification of a recipient plant with gene(s) from any non‐plant organism, or from a donor plant that is sexually incompatible with the recipient plant, the results of cisgenesis could occur naturally over time. Currently, both cisgenic and transgenic products are classified as genetically modified organisms (GMOs) and are labeled as such …
Price Discovery And Futures Spreads For U.S. And Chinese Rice Futures Market, Wei Yang
Price Discovery And Futures Spreads For U.S. And Chinese Rice Futures Market, Wei Yang
Graduate Theses and Dissertations
Rice, the primary staple food for more than half the world's population, is the second world's most consumed food grain. In recent years, world rice price has increased and become more volatile especially in the period 2007-2010. Rice price volatility has a huge impact on Asian countries, especially countries in Southeast Asia where rice is a staple food for millions of households. Private market tools to manage price risk and discover price such as futures markets have been analyzed and assessed as possible solutions to coping with rice price volatility issue. Two primary functions of agricultural commodities futures markets are …
The Economic Viability Of Cocoa Crop Insurance In Ghana, Justin D. Mckinley
The Economic Viability Of Cocoa Crop Insurance In Ghana, Justin D. Mckinley
Graduate Theses and Dissertations
This study was motivated by the fact that Ghanaian cocoa producers face lower yields than other main cocoa producing counties which in turn increases food insecurity for smallholder producers. In addition, low yields experienced by Ghanaian producers is a driving factor for forest degradation and deforestation as cocoa producers encroach further into previously undisturbed forests in efforts to increase their incomes. There are currently production methods to achieve higher yields readily available in Ghana; however, many producers choose not to adopt these methods because they are seen as too risky, or simply cannot adopt them due to financial/credit constraints. A …
Assessing Net Returns To Blueberry Production Using A Decision Support Tool, Sokha Sok
Assessing Net Returns To Blueberry Production Using A Decision Support Tool, Sokha Sok
Graduate Theses and Dissertations
The purpose of this study was to develop and assess the profitability of four highbush blueberry farming systems in the south: organic field production, conventional field production, organic high tunnel production and conventional high tunnel production. Four baseline budget scenarios, one for each system, are developed for a 15 year production period. The results suggest that under expected production and price conditions for Northwest Arkansas, while all four production systems generated positive present value of net returns, the conventional field production produced the highest present value of net returns across the 15 years. The breakeven years of production were 7 …
Population Genetics, Distributions And Phenology Of Bombus Latreille, 1802 And Xylocopa Latreille, 1802 (Hymenoptera: Apidae), Amber Dawn Tripodi
Population Genetics, Distributions And Phenology Of Bombus Latreille, 1802 And Xylocopa Latreille, 1802 (Hymenoptera: Apidae), Amber Dawn Tripodi
Graduate Theses and Dissertations
This work addresses multiple knowledge gaps in bee ecology, population health and phylogeography in order to provide insights into the changing distributions of native bees. A comparison of Arkansas bumble bee records mirrors range-wide surveys, with records of stable species (Bombus bimaculatus Cresson, 1863 and B. impatiens Cresson, 1863) increasing three-fold, and records of the declining B. pensylvanicus (DeGeer, 1773) dropping to 60% of historical levels. However, nationally-recommended conservation-genetics tools did not mirror these results on a regional level. Stable and declining species had equivalent genetic diversity in samples from Arkansas and Tennessee (HS range: 0.46-0.63). Diploid males, …
Identification And Development Of The Support Needs In Nematology For Arkansas Cooperative Extension Personnel, Mia Gentry
Graduate Theses and Dissertations
County extension agents are vital to the land-grant university system and are responsible for transferring current, research-based knowledge from the university to the community. In-service training allows agents the means to maintain a current, sound knowledge base. Needs identified by leading nematologists led the researcher of this study to assess if nematology education was a topic that warranted in-service training development for Arkansas Cooperative Extension Service (CES) agents. The researcher also assessed agents' comfort level with job related technology. Of the respondents, 67% identified general knowledge of plant parasitic nematodes necessary to meet the needs of their clientele. Findings from …
A Mixed Methods Approach Of Communication Campaign Development And Assessment: Identifying The Needs Of An Audience And Determining The Value In Evaluation, Tara Johnson
Graduate Theses and Dissertations
The two articles presented in this thesis used both quantitative and qualitative research methods to examine two distinct stages of communication campaigns: research and evaluation. In the quantitative study, students (n = 440) at the University of Arkansas were surveyed to determine their perceptions of the Arkansas Water Resources Center (AWRC), water resources, and water issues. A questionnaire was developed from an existing instrument, reviewed by a panel of experts, pilot tested, and revised. The researchers found participants were most aware (M = 3.23, SD = 1.14), concerned (M = 4.07, SD = 0.86), and interested (M = 4.10, SD …
