Leaders are generally viewed in a positive frame as having the ability to influence and motivate others (Tierney, 2005). They are frequently required to make choices in order to lead their organizations. Those choices are often influenced by the opinions of followers and public opinion in general (McIntosh, Cacciola, Clermont & Keniry, 2001). Understanding the opinion formation process, how leaders formulate opinions and how they make choices in leading their organizations is still at issue (Burns, 1978; Gardner, 1990). One of the goals of higher education is to create student leaders who are contributing members of society and who are able to generate informed opinions. The purpose of this study was to explore the influence of student-student interactions on change of opinion among student leaders (SLs) and non-student leaders (NSLs). This study compared differences between student leaders and non-student leaders, and sought to examine which types of discussions with students different from oneself, best predict change in opinion. Data from the 2004 College Student Experience Questionnaire (CSEQ) (Pace, 1984) were used in the study. The CSEQ asks respondents about their involvement with leadership experiences and the degree to which they have influenced others' opinions and been influenced by others' opinions. Participants also report how often they have become acquainted with or had discussions with other students who are different from themselves based on several characteristics. These characteristics referred to individuals who had different interests, philosophies of life or personal values, political opinions, religious beliefs, race or ethnic backgrounds, family backgrounds or were from different countries. Data were analyzed via logistic regression and t-tests. Findings revealed that discussions with other students who are different from oneself in regards to political values and country of origin lead to higher levels of opinion change. Opinion change, then, is influenced by specific types of discussions, and these discussions have an even greater influence on SLs than NSLs. In addition, highly involved SLs engage in discussions with others different from oneself significantly more often than less involved SLs for each of the seven types of discussions. / Ph. D.

Excess phosphorus (P) that is transported into water bodies can cause water quality problems. A high potential for P delivery occurs when there is a high transport potential from erosion, runoff, and/or leaching coupled with high soil test P and/or high rate of fertilizer P application. A management tool is needed to identify those fields that have a high transport and source potential to deliver P to surface water. The Virginia P-Index is a mass-based tool that estimates the annual risk of delivery of P from a given field to surface water. Guidelines on P application rates are then given based on the level of risk. This is a new tool and additional research and testing are needed to determine the dependability and validity of the index. The overall goal of the research was to contribute to the continued development of the Virginia P-Index as an effective P management tool. A sensitivity analysis was completed to identify the parameters to which the P-Index was most sensitive under a range of conditions. In low erosion and runoff conditions, the P-Index was most sensitive to P management factors including application rate. As erosion and runoff potential increased, the P-Index was most sensitive to the erosion risk factors including soil loss. Under conditions with subsurface leaching, the P-Index was most sensitive to the subsurface leaching factors and Mehlich I soil test P. A stochastic analysis was also conducted to determine the effects of parameter variability. Variability of the P-Index output was greater as the risk of P delivery increased and this could affect management recommendations. A survey was completed to determine expert opinion as to the appropriateness of parameter estimation methods used in the Virginia P-Index. Thirty-eight surveys were returned, representing a diverse range of participants within and outside of Virginia. Comments from the respondents were used to evaluate the appropriateness of the parameter methods. All factors were determined to be appropriate given the state of the science. Estimation methods for the following factors were determined to be less appropriate than the other sub-factors by the survey respondents: soil texture/drainage class, subsurface dissolved reactive orthophosphate (DRP), runoff delivery, and sediment delivery. The Virginia P-Index was determined to be a well thought out management tool and implementation should identify fields with the greatest risk of P delivery to surface water. Recommendations for improvement were identified including a need for additional analysis and studies. / Master of Science

During the 2016 presidential election, public opinion polls consistently showed a lead in the popular vote and Electoral College for Hillary Clinton over Donald Trump. Following Trump's surprise victory, the political pundits and public at large began to question the accuracy of modern public opinion polling. Fielding a representative sample, convoluted and opaque methodologies, the sheer amount of polls, and both the media's and general public's inability to interpret poll results are among the flaws of the polling industry. An alternative or supplement to traditional polling practices is necessary. This thesis seeks to investigate whether Google Trends can be effectively used as a measure of public opinion during presidential elections. This study gathers polling data from the 2016 presidential election from states that were considered swing states. Specifically, this study examines six total polls, three from states that swung in the way the polls predicted they would – Nevada and Virginia – and three from states that swung against the prediction – Michigan, Wisconsin, and Pennsylvania. Answers to the "Most Important Issue" question in each poll are compared to their corresponding topics in Google Trends by calculating Pearson product moment correlations for each pair. Results indicated that in states that swung as predicted, Google Trends was an effective supplement to traditional public opinion polls. In states that did not swing as predicted, Google Trends was not an effective supplement. Implications of these results and future considerations for the polling industry and Google are discussed. / Master of Arts

Thematic tourist maps provide users with a tangible geographic route to their travel destinations and also may contain a wide variety of additional information to enhance traveler experiences. Unlike other types of maps that focus on accurate topographic representation of an area or on depiction of spatial data, tourist maps should be specifically constructed to appeal directly to the end-user. Toward that end, this research developed and implemented a model to incorporate user opinion on content, levels of detail, and labeling conventions during the process of designing and creating a wine tourism map for southwest Virginia. Over 700 (total) wine tourists completed brief questionnaires during five distinct phases of data collection and map modeling. At each point, we incorporated user input into map design for the preceding phase, and a final assessment surveyed tourist attitude of the finished product. Interestingly, surveys indicated a propensity for users to highly rank the idea of more and more detailed content data, as well as high levels of spatial detail, but when presented with the corresponding maps, they tended to favor a cleaner more simplified display. This finding underscores our conclusion that while user input is critical for developing successful tourist maps, cartographic training and skill is still required to achieve a quality product. Overall, the final map incorporating user input received overwhelmingly positive user reviews when compared to existing regional maps indicating that our iterative method of seeking user input at various stages of map development was successful, and facilitated creation of an improved product. / Master of Science

Ce mémoire propose une analyse de la relation entre la philosophie politique et l’opinion publique. Plus particulièrement, il a pour objectif de définir le rôle de l’opinion publique en philosophie politique en se penchant sur la question de la justice distributive. Le mémoire est divisé en trois chapitres. Le premier chapitre pose les bases théoriques sur la justice sociale et distributive, ainsi que sur la place de la recherche empirique philosophie politique. Le second chapitre constitue une étude de l’opinion publique sur la structure et les déterminants des attitudes sur la justice distributive au Canada, au Royaume-Uni et aux États-Unis. Le troisième chapitre offre une proposition théorique originale du rôle de l’opinion publique en philosophie politique. Nous y présentons quatre arguments en faveur de l’inclusion de l’opinion publique en philosophie politique par le biais de la notion d’équilibre réflexif public. / This Master’s thesis offers an analysis of the relationship between political philosophy and public opinion. More specifically, its objective is to define the role of public opinion in political philosophy in relation to the issue of distributive justice. The thesis is divided into three chapters. The first chapter lays the theoretical foundations on the issues of social and distributive justice, as well as on the place of empirical research in political philosophy. The second chapter is an empirical public opinion research on the structure and determinants of attitudes toward distributive justice in Canada, the United Kingdom and the United States. The third chapter presents an original theoretical proposition of the role of public opinion in political philosophy. We put forward four arguments in favor of the inclusion of public opinion in political philosophy through the notion of public reflective equilibrium.

The United States is built on the core idea that the government is run by the people. Vital to this idea is that the public opinion of the masses is a main consideration of political elites in the formation of policy. By analyzing six issues, looking at both the policy opinion of the masses and actual related policy, levels of correlation between opinion and policy will be demonstrated. The results vary depending on the issue, ranging from a very high correlation to a very low correlation. The research also looks at saliency, or importance, of each issue to the respondents. This serves to demonstrate which public opinion political elites are acknowledging when forming policy, those who care about the issue or those who do not. Understanding levels of saliency can help to better prioritize the importance of which issues should be addressed by elites in order to create greater governmental efficiency.
