A study examining the effects of public relations' dialogical communication strategies on stakeholder's perceptions of trust and authenticity of organizations was conducted. The experiment was tested on organizational Facebook posts broadcasting a corporate social responsibility message. While "Human Voice" had no affect on perceived trustworthiness or authenticity, Dialogical Loop was found to significantly effect stakeholder perceptions of authenticity, but not trustworthiness. Due to the presence Dialogical Loop in the form of replies to user comments, users perceived the organization as less authentic. Ruminations about possible implications for public relations theory and practice on social media as well as recommendations for further study of the Facebook platform is discussed.

The deuterium content of sugar in fruits is influenced mainly by two factors – the botanical and also the geographical origin of the fruit. The information of the fruit origin is kept even after fermentation of the sugar, in the molecules of ethanol. The deuterium content on the methyl group of ethanol then varies depending upon the botanical origin of the fruit. SNIF-NMR (Site-specific Natural Isotope Fractionation – Nuclear Magnetic Resonance) is a specific method for determination of the deuterium isotopic ratio (D/H) in small molecules, e.g. ethanol. This isotopic technique is widely used for determination of sugar adulteration of fruit-based beverages (wines, fruit juices..). In this thesis, the authentic samples of five different fruits (apples, oranges, grapefruits, pineapples and grapes) available in the Czech market have been collected and analyzed by SNIF-NMR. The results are presented as well as the comparison to some commercially available fruit juices and nectars.

This paper attempts to mark out new ground in the connections between the philosophical writings of Martin Heidegger and Aristotle by posing an interesting question that has never been addressed. Both writers devote much of their early thoughts to questions concerning human beings' practical ways of understanding. However, in their later thoughts Heidegger and Aristotle suddenly seem to completely change the subject to ideal or transcendental ways of understanding. At first glance these ideal modes of human apprehension seem to have nothing to do with each other. Yet, Heidegger and Aristotle seem to have similar motives for turning away from the practical realm and towards a transcendental realm, and they seem to have similar outcomes. My investigation of their respective motives and outcomes has led me to believe that although there are some similarities that are thought provoking, they are not strong enough to conclude that Heidegger's later writings are connected to his recovery of Aristotelian ideas. Given that the core of Heidegger's early questions of Being can be interpreted as a retrieval of Aristotle, to be able to demarcate the point at which Heidegger ceases his attempts at this recovery may allow us to examine the differences in Heidegger's later thought concerning Being.

This paper aims to explore and understand how locals and tourists perceive authenticity on a truly authentic heritage site. The empirical study was conducted with a sample of Scandinavians and South Africans that had or had not visited the heritage site in Cape Town, Republic of South Africa. The result indicated a correlation between authenticity and heritage experience. The most interesting finding was however when heritage was positioned somewhere else but the individuals' home countries. These findings provide insight into the ways tourists and locals perceive authenticity and the demand for heritage tourism and true authenticity, which highlights the importance of authenticity in tourism destinations.

This paper examines the relationship between the sensory experience of food and cooking, how these sensory phenomena interact with questions of authenticity and memory and how this affects the process through which migrants rebuild a sense of home in theirhost nations. The data for this study has been collected through a version of short-term ethnography, where the researcher also participated in cooking sessions, which were video-recorded, in conjunction with the interviews. The findings of this study are that the sensory qualities of food are important markers of the authenticity of the food, and that this sensory authenticity has a strong ability to invoke both memories and feelings of connectedness. The conclusion drawn is that food and cooking undergotransmutational change when affected by migration, turning them from important but everyday phenomena into a series of ritual actions. The effect of these rituals is to temporarily suspend the liminal state inherent to migration and they are thus very important to the ability of migrants to be able to recreate a stable sense of home in a new place.

Leadership is a critical aspect of organizational success. There have been many leadership styles and models that have emerged from the efforts of both practitioners and researchers. In the early 2000s, authentic leadership offered the potential to be the next prominent leadership style. However, the evolution of the theory never established significant momentum, in part because of the lack of a clear and consistent definition of what it means to be an authentic leader. This is the first study to use a multi-disciplined qualitative approach for evaluating authenticity and leadership. Using grounded theory, this study attempted to revisit authentic leadership by decoupling authenticity from leadership and exploring what it means to be authentic in the context of leadership. Study One used interviews to examine authenticity in leadership by capturing how a diverse group of leaders conceptualize, observe and experience authenticity. The grounded theory analysis revealed themes and construct variables that were consistent with existing authentic leadership literature. In addition, new construct variables of fear and shifting of shared norms emerged to provide further understanding of the relationship between authenticity and leadership. Study One proposed exploring a new conceptual model for high authenticity in leadership. Study Two seeks to refine the conceptual model by further investigating the newly identified construct variables of fear and shifting of shared norms. This will be accomplished by performing a second series of interviews with another sample of leaders. Similar to Study One, a grounded theory approach was used to interpret respondent data and draw conclusions. / Business Administration/Interdisciplinary

This study explores various notions of authenticity in tourism experience and seeks to establish if these notions are compatible with the concept of authenticity in conservation of the built environment. Three wine farms in the Cape Winelands cultural landscape, a proposed serial World Heritage Site, have been studied. The study suggests that object-related or material authenticity is being replaced with alternative notions of authenticity in tourism and that the toured object, for the purpose of winelands tourism in the Western Cape during this period, no longer needs to be authentic.

Sexual minorities, or those who do not identify as straight, experience stigma that has been associated with a number of health issues and decreased quality of life. The current study expands on previous explanations of the relationship between stigma experienced by sexual minorities and quality of life by examining self-compassion and authenticity as potential mediators. We proposed and examined a mediation model in which self-compassion and authenticity would explain the relationship between stigma and quality of life, using data from a sample of 213 sexual minorities. Results of structural equation modeling revealed that there was no direct relationship between public stigma and quality of life but that public stigma and quality of life were indirectly related through internalized stigma, authenticity, and self-compassion. These findings have implications for the understanding of sexual minority experience of stigma and highlight potential points of intervention for increasing quality of life among sexual minority individuals.
