In the higher education environment today, lack of agreement about background checks between campus community members, fueled by unresolved tensions between security and privacy, has led many universities to adopt a patchwork of fragmented background check policies. Many of these policies have been created and accepted without careful consideration of the wide array of risks and complexities involved with background checks. This policy analysis examined the experiences and history behind Georgia Institute of Technology’s adoption of background check policy. This was achieved through interviewing relevant constituents and analyzing of all available/related official policy documents associated with Georgia Tech’s Pre-employment Background Check Policy and Program. This dissertation presents a chronological account of the events and influences associated with Georgia Tech’s adoption and revision of background check policy. Results of this study offer valuable insights and recommendations for further study in order to assist higher education policy makers and HR professionals at other universities in making more informed decisions regarding the challenges involved with background check, and similar, policy. Some of these insights include an awareness of societal tensions that exist between privacy and security policy; the importance of understanding how national, local, and organizational level triggering events have shaped and contributed to higher education background check policy that is based on a general concern for security; and my recommendation for further study into background check policy as it will relate to the higher matriculation process.

<p>In Chapter 1, I document a negative (positive) relationship between changes in large (small) blockholders' ownership and abnormal returns. The evidence in this paper suggests that an increase in the relatively large blockholders' ownership raises the consumption of private benefits while an increase in the relatively small blockholders' ownership constrains large blockholders from expropriating minority shareholders. Moreover, I find an inversely U-shaped relationship between changes in the largest blockholders' ownership and firm value. As large blockholders' ownership and control increase, the negative effect of firm value driven by expropriating minority shareholders starts to exceed the incentive benefits of monitoring by the largest blockholder. I also show that the negative relationship between changes in institutional investors' control and abnormal returns declines as analysts' following increases.</p><p>In Chapter 2, I study the role of trading as a governance mechanism. I hypothesize that governance through trading plays a significant monitoring role in practice and that engaging in "voice" and "exit" can be substitutes. I show that abnormal turnover following earnings announcements is significantly higher for firms with large institutional blockholders than for those with small individual</p><p>shareholders. For firms with majority institutional ownership, I demonstrate that abnormal trading is higher for firms with multiple blockholders than for those with a single large blockholder and that abnormal trading increases with the number of institutional investors and declines with the percent of stocks owned by the</p><p>largest institutional investor. Moreover, this excess trading is driven by mutual fund investors, which are non-interventionist and thus are more likely to engage in "exit" than "voice". I also show that for firms with large institutional blockholders, abnormal trading following public announcements increases with liquidity.</p> / Dissertation

In this thesis, the growth of nonpolar m-plane zinc oxide (ZnO) nano-materials on (100) £^¡VLiAlO2 (LAO) substrates by a chemical vapor deposition (CVD) process had been studied. The mixture powders of ZnO and graphite are used as the precursor of reaction sources. Ar/O2 are used as the carrier gas and reaction gas source respectively, and the Au thin-film coated on the LAO substrate is the catalyst for the vapor-liquid-solid (VLS) growth mode. The X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to study the influence of the varied growth conditions, such as deposition time, reaction pressure, growth temperature, and the distance between substrates and reaction powder ¡K etc., on the crystal structure, surface morphology, orientation and microstructure characterizations of the ZnO nanostructure. The pure (10-10) m-plane ZnO nano-materials can be obtained at the growth parameters of 830¢XC, 10 torr, 5 minutes, and 50 sccm of Ar/O2. Furthermore, photoluminescence (PL), cathodoluminescence (CL) and Raman spectroscope (Raman) were used to study optical properties and the inner stress of the materials.

The thesis questions the ways in which architecture might embody the notion of modernity in different cultures and regions yet achieve appropriateness relative to place. In the early twentieth century in the industrialized world, the issue of modernity in architecture was identified with the notions of abstraction and rationalization that colored the development of the modern movement. The second generation of the modern movement queried the roles of human experiences and urban and architectural contexts in architectural design. With the spread of the modern movement to the rest of the world, the issue of context in architecture grew stronger. Following this line of thought, this dissertation examines the tension between modernist abstractionism and urban and architectural contexts in place in which the presence and the role of local knowledge and traditions in architecture remained influential. It investigates modernity in architecture through a specific Asian reading and through an analysis of the work of Geoffrey Bawa of Sri Lanka. Selected works of Geoffrey Bawa are chosen because the significance of his oeuvre is often contested by interpreters who see it as reflecting various contemporary approaches, including regionalism and vernacularism. Thus, in an effort to refute such simplistic explanations of his work, this thesis examines selected works of Bawa, analyzing their spatial organization, formal arrangement, materials, techniques, and building details. In particular, it attempts to highlight the ways in which Bawa articulated the notions of experience and memory in his architecture. These analyses are then placed within the framework of the social and cultural situations that his architecture confronted in Sri Lanka. It is within this framework that we might determine the ways in which modernity and locality were embodied in Bawa's work. Interpretations of his work take into account the understanding of modernity as a cultural practice and an attitude. Modernity as an attitude relates to a specific modernist subject who is able to use reason for judgment in addressing context. In this dissertation, a reading on the work of Walter Benjamin on modernity, the pasts, and traditions frames this understanding of this modernist subjectivity. In architecture, modernity as an attitude means that is not a style but a way of thinking and formulating design intent. This inquiry is then used as a framework within which this dissertation will interpret the relationship between modernity and local identity. The conclusions of the dissertation contribute to an understanding of the achievement of modernity in architecture in tight relationship to context. On a more focused level, it also hopes to contribute to an appreciation of the extant works of Geoffrey Bawa, which the author of this dissertation deems exemplary of what modern architecture might achieve in Asia.

Le modèle de récit (« Story Model » ; Pennington & Hastie, 1993) suppose qu'une logique de construction narrative des preuves détermine les jugements de culpabilité des jurés. Développé dans le cadre de la procédure judiciaire nord-américaine, ce modèle a été validé selon des méthodologies expérimentales reflétant le contexte procédural accusatoire. L'objectif de la thèse est de mettre à l'épreuve le modèle du récit dans le cadre de la construction des jugements des jurés insérés dans la procédure judiciaire inquisitoire française. Cette dernière se caractérise notamment par l'instruction préalable au procès, menée par un juge, visant à réunir les preuves de manière impartiale. La lecture des conclusions du juge d'instruction, consignées dans une « ordonnance de renvoi », à l'ouverture du procès est le premier contact officiel des jurés avec l'affaire qu'ils vont juger. Dès lors, la mise en récit des preuves figurant dans l'ordonnance de renvoi peut s'avérer déterminante dans la construction des jugements des jurés. Tout d'abord, une analyse de la structure et du style discursif d'un corpus d'ordonnances de renvoi met en évidence une variabilité relativement importante dans le rapport des preuves. Puis, un programme expérimental de six études a été mené afin de tester des hypothèses concernant les conséquences de l'organisation de l'information dans les ordonnances de renvoi. Les résultats obtenus sont inverses aux prédictions du modèle du récit et ont conduit à définir des conditions plus spécifiques de la validité prédictive du modèle dans le cadre d'une procédure inquisitoire. Plus largement, l'ensemble de ce travail pose la question de la transposition de modèles psychologiques entre systèmes et cultures juridiques différents.

This study is based on 72 children's and young adult books that met the criteria of being about Muslims and published and circulated here in the U.S. They can be divided into the varied genres as 49 contemporary realistic fiction, 6 historical fiction, and 17 autobiographies, biographies, and memoirs. In-depth reading and coding were used to identify patterns based on a theoretical frame of postcolonial theory and the lens of cultural authenticity.The exploration of ideas focus on the following research questions related to children's and adolescent literature published and distributed in the US that depict Muslim cultures: What are the overall characteristics of the books? What are the background experiences of the authors, illustrators, and translators who write and distribute literature within the U.S. that reflect Muslim Cultures? How do the genres of contemporary realistic fiction, historical fiction, and biographies published for adolescents and children within the U.S. represent and frame the varied Muslim cultures? What are the relationships between the background experiences of the authors and the representations of Muslim cultures in their books?This work is grounded in the assumption that Muslims are presented in a certain manner in popular culture and literature in the U.S., and thus, postcolonial theory is relevant in unpacking issues within the literature about these people. This theory draws on these suppositions to unveil how knowledge is constructed and circulated in dealing with global power relations. It also sheds light on how the identities of natives become hybrids as the process of colonization in certain cases impacts the psyche of inhabitants of these regions.This study is a `critical content analysis' in comprehending how texts are based in the social, cultural, and political contexts in which they are created and read. Content analyses examine what texts are about, considering the content from a particular perspective. This method scaffolds and explained my research to support my analysis of the texts through postcolonial perspectives to observe how Muslims are portrayed within adolescent and children's literature in the U.S.

Syftet med denna studie är att undersöka och söka förståelse för avståndstagande från sociala medier. Detta är en företeelse som idag tycks bli allt vanligare fenomen bland användare av sociala medier, i synnerhet på Facebook. Med anledning av detta har jag därmed valt att begränsa studien genom att undersöka avståndstagande från just detta sociala nätverk. För att undersöka fenomenet har jag studerat hur användare av sociala medier förklarar orsakerna till avståndstagande, hur de upplever att de har påverkats av det samt undersökt på vilket sätt avståndstagande kan tolkas och förstås som politiska eller apolitiska handlingar och resonemang. För att ge svar på studiens syfte och frågeställningar har jag använt mig av en kvalitativ metod i form av enskilda samtalsintervjuer som bidrar till en djupare förståelse för respondenternas avståndstagande. Studien tar sin utgångspunkt i José van Dijcks teorier kring de sociala mediernas normalisering, teorier om digitala kommunikationsteknologiers påverkan av socialitet och identitetskapande som bland annat beskrivs av Sherry Turkle samt Anne Kaun och Laura Portwood-Stacers tankar kring mediekritisk aktivism och livsstilspolitik. Den kan ytterligare ses som en utveckling av tidigare forskning av bland andra Stefan Stieger som kretsar kring orsakerna till medieavhopp. Studien visade att avståndstagande från sociala medier är en företeelse som ser ut på många skilda sätt och innefattar en mängd orsaker och konsekvenser som främst bör förstås på ett individuellt plan. Handlingen omges av en positiv uppfattning och pendlar mellan aktiv mediekritik och identitetssökande som präglas av individuella och apolitiska resonemang.

As online gaming becomes more popular, it has also become increasingly important to identify and remove those who leverage automated player systems (bots). Manual bot detection depends on the ability of game administrators to differentiate between bots and normal players. The objective of this thesis was to determine whether expert poker players can differentiate between bot and human players in Texas Hold ‘Em Poker. Participants were deceived into thinking a number of bots and humans were playing in gameplay videos and asked to rate player botness and skill. Results showed that participants made similar observations about player behaviour, yet used these observations to reach differing conclusions about whether a given player was a bot or a human. These results cast doubt on the reliability of manual bot detection systems for online poker, yet also show that experts agree on what constitutes skilled play within such an environment.
