Conjoint Analysis to Determine Relative Importance of Cotton Sprayer Features

Kaufman, Kyndall Rae 01 December 2010 (has links)
Deciding which features to include on a sprayer in order to increase a purchaser's likelihood of buying was a major problem for spray equipment manufacturers. There were several sprayer options that could be included or excluded that affect the retail price of the cotton sprayer. Conjoint analysis was utilized to determine the relative rank and value of features on a cotton sprayer. At the Georgia Cotton Commission Conference, ninety-five respondents completed a sorting of eight cards that each contained groupings of five cotton sprayer feature options. A demographics page was used to identify respondents that were farmer-buyers. The number of participants used in the study was fifty-six. The rankings from this study were entered into SPSS statistical software to retrieve utility values, importance values, and correlations. The analysis of the data showed that the inclusion of chlorophyll sensors had the largest influence on a purchaser's decision to buy. Following this, in terms of importance was presence of wheel shields, type of wheel tread adjustment, and number of spray boom sections. The highest ranking feature combination was three chlorophyll sensors, the presence of shields, hydraulic tread adjustment, and two boom plumbing sections. Chlorophyll sensors were twice as important to respondents as all other features. The respondents were willing to pay the extra cost for the three chlorophyll sensors, proving that the technology was important to them. Once the price increased additionally for the six chlorophyll sensors the respondents' preference for the technology was overshadowed by their preference for price. This showed a strong trade-off with price. It appears that they may be unwilling to pay for the technology because they do not fully understand the benefits of variable rate technology or feel that the technoology cost will not be offset with the benefits.

Production Model and Consumer Preferences for Texas Pecans

Chammoun, Christopher James 2012 August 1900 (has links)
High prices in any industry, agricultural especially, tend to spur new investment opportunities. Recent prices for pecans have been high relative to their historical pattern, suggesting investment opportunities for pecans. Prior to any investment, the investor needs to know what products consumers are demanding and how profitable it is to grow those products. This study assessed Texas consumers' preferences for pecan products and the profitability of growing pecans in the central Texas region. A choice experiment was conducted amongst Texas consumers to reveal consumers' preferences and determine their willingness-to-pay for the attributes comprising pecan products. A stochastic production model was formulated to determine the profitability of three different types of pecan orchards: a native orchard with no irrigation, an improved varieties orchard with irrigation, and an improved varieties orchard without irrigation. Results from the choice experiment indicated that consumers preferred large size pecans, native variety pecans, pecan halves, United States-grown pecans, and Texas-grown pecans. The choice experiment also found that consumers were heterogeneous in their preferences for all attributes except pecan variety and U.S. origin. Results from the stochastic production model indicated that the most profitable pecan orchard in central Texas was the irrigated improved orchard.

A Study on Land Use and Zoning Regulation System of Kaohsiung City: An Application of Conjoint Analysis

Yang, Chang-Dar 16 January 2007 (has links)
In the last decade, both transport and communication technologies have advanced significantly, and international interactions between countries no longer are limited by distance, the world is changing in a great speed. In the same time, Kaohsiung also faces major changes. The opening of Taiwan High-speed Railway and Kaohsiung city's new MRT system will have a significant impact on its¡¦ development, and will definitely bring new problems and needs to the city. Facing the changes of city-region competition and cooperation, domestic economical and political situation, the city's urban development is already linked together with the international progress. With the impacts of global competition, the rapid rate of information exchange, the rise of community awareness, this is the crucial moment which holds the key to the long term transformation of Kaohsiung city¡¦s future improvement. However, one main element that decides the competitiveness of a city is the city¡¦s land use and zoning regulation system. Therefore, the government with reference to social background, economic conditions, land policies, and national development¡Ketc, sets the best suited land use and regulation system for guidance. This study uses conjoint analysis to review the policies of Kaohsiung city¡¦s land use and zoning regulation system, and by calculating the total preference values of all the alternatives to pick out the best suited option, by translating the attributes into different policy options, and reviewing them through conjoint analysis by questionnaires answered by scholars and workers in related fields, with consideration of two criteria, ¡§the degree of difficulty for legislating or amending laws¡¨ and ¡¨ government administrative efficiency¡¨, to determine urban development issues and be the basis for government agencies to make future policy judgments. According to the result of conjoint analysis, the best option is: 1. the legislating of ¡§Kaohsiung land use and zoning regulation rules¡¨; 2.the zoning districts should be made in the form of a positive list, only the districts listed are allowed; 3. amend ¡§Urban Planning Commission¡¨ to ¡§City plan commission¡¨ and ¡§Zoning commission¡¨; 4. the new establishment of ¡§Board of Adjustments¡¨ as a public channel for complaints. In addition to providing policy recommendations, this study wishes not only to improve the efficiency and effectiveness of land use in Kaohsiung, and also make conjoint analysis more applied on policy analysis.

A incompatibilidade entre os atributos dos recursos educacionais abertos e as preferências dos usuários como barreira à difusão de inovação / The incompatibility between Open Educational Resources attributes and users preferences as a barrier to the diffusion of innovation

Correa, Juliana Nelia do Nascimento 19 October 2018 (has links)
Os Recursos Educacionais Abertos (REA) são materiais com finalidade educacional, principalmente em meio digital, publicados sob termos de propriedade intelectual que autorizam seu uso, modificação, revisão e compartilhamento sem restrições. Esses recursos, idealizados com o objetivo de democratizar o acesso à educação, a despeito de sua gratuidade, de estarem disponíveis em meio digital e de geralmente elaborados por universidades renomadas, têm sido menos utilizados do que o esperado em localidades-alvo: países em desenvolvimento, onde as desigualdades de acesso a oportunidades educacionais de qualidade são maiores. Com base na teoria de difusão de inovação e no conceito de abismo de inovação, foi levantada a hipótese de que os atributos da proposta de valor dos REA não correspondem às preferências de usuários em países em desenvolvimento. A técnica de Conjoint Analysis foi empregada para avaliar as preferências de usuários em potencial (adultos com acesso à internet e redes sociais, que podem decidir individualmente sobre o uso dos REA) sobre os atributos de um tipo de REA (cursos online, cuja observabilidade é maior do que os REA como componentes modulares utilizados na educação formal), cujos atributos foram selecionados a partir de uma revisão conceitual da literatura, elaborada de forma sistemática. Os resultados mostraram que a importância relativa dos dois atributos da proposta de valor dos REA mais utilizados como argumento de diferenciação (licença de propriedade e reputação da instituição) não se mostrou significante na avaliação da utilidade total percebida nas propostas de cursos online gratuitos. Em contrapartida, os atributos que são mais difíceis de adicionar aos REA (certificação, suporte e idioma) são os mais importantes para os respondentes. / Open Educational Resources (OER) are education-driven materials, mainly in digital formats, released under intellectual property licenses that allow their use, modification, revision and sharing with no restrictions. These resources were developed to democratize access to education. However, despite their free status, their digital availability and the reputation of the universities that release them, their use have been lower than expected in target locations: developing countries, where remain the greatest inequalities in access to quality educational opportunities. Based on the diffusion of innovation theory and on the concept of innovation chasm, we\'ve raised the hypothesis that the attributes of the value proposition of OER are not compatible to users\' preferences in developing countries. The Conjoint Analysis technique was used to evaluate the preferences of potential users (adults with internet access and access to social networks websites, who can decide on the use of OER by themselves) on the attributes of a type of OER (online courses, whose observability is higher than the OER as modular components used in formal education), whose attributes were selected based on a conceptual review of the literature, conducted in a systematic approach. The results showed that there was no evidence that the relative importance of the two main attributes of the OER\'s value proposition, most used as an argument for differentiation (intellectual property license and institutional reputation) is significant in the evaluation of the total utility perceived in the proposals of free online courses. In contrast, attributes that are harder to add to OER (certification, support, and language) are the most important attributes for respondents.
