Speakers of American Sign Language use surrogates and tokens throughout their discourse. Surrogates allow signers to shift roles (or perspectives) and “become” a character or other entity in their discourse. Tokens allow them to miniaturize entities and bring them into a smaller signing space. Scott Liddell claims that surrogates and tokens cannot interact or converse with one another. He states that because surrogates are in the “here and now” and tokens are not, they are unable to interact with each other. He also claims that surrogates and tokens are unable to enter each other’s signing spaces. In this research project, I explore examples that show otherwise. I have found examples where surrogates and tokens would be able to converse with one another, should the need arise. I have also found examples of tokens entering surrogate space, giving them the “here and now” feature Liddell says they do not possess. / May 2016

Applications store more data than ever before, including sensitive information such as user data, credit card information, and company secrets. Due to the value of this data, malicious actors have a financial incentive to employ a variety of attacks against applications in order to gain access to it. As a consequence, application owners protect data behind authorization systems, with a common solution being token-based authentication systems in which the user’s client receives and stores an access token after successful authentication. Developers seeking to create secure and effective applications face a number of questions. How do clients store these tokens and are they vulnerable to attack? What is the most secure way to store these tokens, and how do different storage methods impact the user experience? The objective of this study is to answer these questions by comparing current storage methods available to developers of frontend applications. Literature was reviewed and an empirical study conducted so that comparisons could be made. Six storage options were found to be viable choices for review and ultimately it was concluded that In-memory storage with closures was the most secure storage option, but that this choice could have an impact on the usability of the application depending on the user desire for data persistence.

Le thème général de cette thèse est l’identité linguistique: la relation qui fait que différents éléments linguistiques comptent comme "un même élément" ou comme “identiques” même s'ils sont hétérogènes d'un point de vue interne ou présentent des propriétés de surface différentes. Je traite de six questions sur ce thème.Le chapitre 1 concerne les segments phonétiques. La phonétique traditionnelle modélise la parole continue comme une concaténation de segments discrets de durées temporelles non spécifiées. Cependant, au cours des dernières années, les idéalisations segmentales de la parole ont été remises en question par des approches éliminativistes à l’égard des segments phonétiques. Le chapitre tente de justifier la phonétique segmentale face aux arguments éliminativistes.Le chapitre 2 concerne les objets phonologiques. Les énoncés phonologiques quantifient sur les phonèmes, qui sont des entités controversées. Aucune ontologie standard n'accepte de les faire figurer parmi l’“ameublement du monde”. Par conséquent, se pose la question suivante: comment les énoncés de règles phonologiques parviennent-ils à recevoir les valeurs de vérité attendues ? Le chapitre propose d'aborder la question en appliquant le non-factualisme de Stephen Yablo aux objets phonologiques.Le chapitre 3 traite du problème type-token. Il existe plusieurs théories concurrentes de la relation spécifique désignée par le prédicat “est un token de”, tel qu’on l'emploie dans le domaine linguistique. La théorie dominante est que les tokens instancient les types, mais cette thèse fait face à plusieurs difficultés conceptuelles. S'appuyant sur des travaux antérieurs de Zoltan Szabó, le chapitre propose une nouvelle approche du problème type-token, basée sur l'idée que les sons et les inscriptions du langage représentent des formes phonologiques et orthographiques.Le chapitre 4 traite du comptage de mots. Selon certains, l'identité des mot-types dépend de leur similarité en matière d'attributs structurel-fonctionnels. Selon d'autres, l'identité des mot-types dépend de leur lignée historique-causale. Les deux cadres donnent lieu à des manière différentes de compter les mots. Lequel d'entre eux est métaphysiquement adéquat ? Le chapitre propose une théorie quiétiste du comptage de mots, en soutenant qu'il n'y a pas de réponse factuelle et non-théorique à la question de “combien de mot-types existent” dans un monde ou scénario linguistique.Le chapitre 5 porte sur un problème dans la théorie de l'anaphore. On pense habituellement que l'anaphore implique la coréférence. Ce principe général, cependant, semble être contredit par des phrases où un pronom non lié hors-citation dépend d'un antécédent dans une citation. Le chapitre soutient que les phrases présentant les caractéristiques décrites ci-dessus n'invalident pas le principe général, et articule une analyse des cas problématiques axée sur la notion de "saillance".Le chapitre 6 porte sur la coréférence de jure. La coréférence de jure est un type particulier de relation de coréférence qui a attiré beaucoup d'attention dans la littérature récente. Cependant, son autonomie par rapport à d'autres variétés de coréférence (notamment la coréférence accidentelle) et ses propriétés distinctives font l'objet de controverses. Le chapitre fournit une présentation systématique des motivations sous-jacentes à l'introduction de la notion de coréférence de jure et défend une approche conservatrice de sa relation avec la grammaire de la phrase: la distinction entre coréférence accidentelle et coréférence de jure est réelle mais invisible du point de vue de la structure linguistique. / The overarching theme of this dissertation is linguistic sameness: the feature by which different bits of language are able to count “as a unit” or as “the same” even if they are internally heterogeneous or exhibit different surface properties. I pursue six issues within this theme.Chapter 1 is about phonetic segments. Mainstream phonetics models continuous speech as a concatenation of discrete, letter-sized segments of unspecified temporal duration. In recent years, however, segment-based idealizations of speech have been called into question by eliminativist approaches to phonetic segments. The chapter attempts to vindicate segmental phonetics in face of the eliminativist arguments.Chapter 2 is about phonological objects. Phonological statements quantify over phonemes, which are controversial particulars. No standard ontology accepts them as part of the furniture of the world. Hence, the question arises of how phonological statements manage to exhibit their perceived distribution of truth values. The chapter proposes to address the issue by applying Stephen Yablo’s non-factualism to phonological objects.Chapter 3 is about the type-token problem. There are competing accounts of what specific relation is designated by the predicate “is a token of” as applied to the linguistic domain. The mainstream view is that tokens instantiate types, but this thesis presents several conceptual difficulties. Building on previous work by Zoltan Szabó, the chapter proposes a novel approach to the type-token problem, one based on the notion that speech sounds and inscriptions represent phonological and orthographic forms.Chapter 4 is about word counting. According to some, word type identity is established by similarity in structural-functional attributes. According to others, word type identity is established by sameness of causal-historical lineage. The two frameworks yield competing word counting policies. Which of them is metaphysically adequate? The chapter articulates a quietist take on word counting, one arguing that there is no non-theoretical fact of the matter about “how many word types exist” in any given language-infused world or scenario.Chapter 5 is about a puzzle in the theory of anaphora. Anaphoric dependency is commonly thought to entail coreference. This mainstream principle, however, appears to be violated by sentences where an off-quote unbound pronoun depends on an antecedent within closed quotation marks. The chapter argues that sentences exhibiting the described pattern do not invalidate the mainstream principle, and articulates a salience-based analysis of the problematic cases.Chapter 6 is about de jure coreference. De jure coreference is a peculiar kind of coreference relation that has attracted much attention in recent research. However, its autonomy from other varieties of coreference (most notably, accidental coreference) and its signature properties are the subject of controversy. The chapter provides a systematic presentation of the motivations underlying the introduction of de jure coreference, and defends a conservative account of its relationship to sentence grammar: the de jure vs. accidental divide is real but invisible from the standpoint of linguistic structure.

This project explores how cosmopolitan personas rhetorically negotiate the space between local and global, discursively tying people to the national as well as to the global or transnational. It examines the possible co-existence of cosmopolitanism and nationalism while identifying how each is articulated in response to the other. As global networks become increasingly complex, rethinking borders and how they are articulated is essential. Can a quintessential cosmopolitan also be a public nationalist? Are cosmopolitan discourses compromised by their presumed lack of attachment to the local? To what extent and with what success are cosmopolitanism and nationalism siultaneously articulated? In order to study these and other questions, I analyze the public personas crafted by cosmopolitan figures Vaclav Havel, Jimmy Carter, and Edward Said. By illuminating how they negotiate that ambiguous space between locale and its absence, a project attentive to the rhetorical possibilities of discursive connection in a world increasingly devoid of shared loyalties and histories enables a fuller understanding of the possibilites of intercultural contact in a globalizing world.

The present study is a corpus-based study which examines social roles constructed in the British nineteenth-century courtroom. To discover the prevalent social roles in British nineteenth-century society the present study focuses on premodifying adjectives characterizing men and women. The method of classification is through semantic domains. The study shows that the social roles of men and women are more similar than the findings of previous research have demonstrated.

This study was focused to highlight the problems that comes with being a minority on a workplace, in this case female sports journalist who are working in a male dominated sports field. The objective was to find out how the female sports journalist was experiencing working in such a domain, with focus on journalists who works on local news papers. The study also wanted to look on how these workplaces incorporated gender in their daily work.        In combination with gender theory, with concepts as masculine hegemony and power structures, I also choose to apply the american researcher Rosabeth M Kanters concept ”token”. With these aspects in mind I analyzed the five interviews that I carried out with female sports journalist with a qualitative data analysis.            The results of the study showed that the female sports journalist in some aspects were aware of the difficulties of being a woman in a male dominated area – when they were talking about the profession at large. But on the other hand they were not as aware when it came to their own situation. Even though the gender problems that comes with being a woman in a patriarchal society, in combination with the minority-issue, the respondents did not express their situation in terms of problem, even though their stories of interview situations for example showed the opposite.              In conclusion, the study showed that even though the respondents really enjoyed their work, even though it was not always easy to cope with. But since their own interest in sports and the profession lead them there in the first place, the obstacles created in society like the minority role they were in or the fact that they are women in a patriarchal society, they kept working in the profession despite the resistance.

The following essays explore ways in which the environment affects and is affected by organizations. The first essay, “Trust and the Division of Labor” considers that the trust environment of a firm helps determine its structure. Jointly with Stephan Meier and Patryk Perkowski, I show that exogenously imposed culture leads to variation in organizational form. An experiment primes trust using past performance from a pilot study and demonstrate that the level of trust within an organization affects division of labor and consequently organizational productivity. This evidence is consistent with a cross-country link between trust and the division of labor that we observe in data from the European Social Survey. A simple evolutionary game theoretic model is provided to illustrate the results. The second essay, Nobody Likes a Rat”, considers the impact of norms against certain types of behavior (in this case dishonesty) on behavior and organizational composition. Jointly with Ernesto Reuben, I investigate the intrinsic motivation of individuals to report, and thereby sanction, fellow group members who lie for personal gain. We find that when groups can select their members, individuals who report lies are generally shunned, even by groups where lying is absent. This facilitates the formation of dishonest groups where lying is prevalent and reporting is nonexistent. Finally, "NFTs, Volume, and Social Influence" observes how organizations and individuals use environmental cues like rankings and volume for sensemaking in a market with high quality uncertainty. Using observational data scraped from the top 1000 NFT collections I find a significant positive relationship between volume and price. Then, using plausibly exogneous variation in blockchain-level transaction fees, I fit an instrumental variable model which helps validate the causal interpretation that changes in volume lead to changes in price. I further add an experiment on NFTs to tease out two plausible channels through which volume could affect prices: user attention and normative social influence. The experiment finds strong evidence that being told an NFT is higher volume leads subjects to pay more attention to that NFT, whereas this has no significant effect on a subject's reported preference for the NFT. A second experimental treatment, in which subjects were told the NFTs were ordered by volume transaction costs, does observe a significant positive affect on reported preferences (as well as attention).

No / Employing a TVP-VAR dynamic connectedness analysis, we identify avenues through which the collapse of the FTX exchange manifested contagion effects throughout a number of financial markets. Results indicate that interaction effects become significantly pronounced, coinciding with key milestones during the collapse of FTX and related companies. Specifically, sources of contagion stem from two tokens created by the exchange and related companies, namely FTT Token and Serum. Such results further develop the expanding literature based on the inherent contagion effects of such unregulated products. / Conlon acknowledges the support of Science Foundation Ireland under Grant Number 16/SPP/33 and 13/RC/2106 and 17/SP/5447.

O objetivo desse estudo foi testar as hipóteses de simetria e assimetria entre reforçamento e punição utilizando análise oriunda da Economia Comportamental. Foram utilizados cinco ratos Sprague Dawley, treinados em uma cadeia comportamental mantida por economia de tokens, em uma caixa tendo como operanda duas rodas e uma barra: respostas de girar a roda produziam tokens (LEDs) e as de pressionar a barra trocavam os tokens por sacarose. O elo de produção de tokens consistia em um esquema concorrente, sendo um oferecendo reforçamento positivo (adição de tokens) e o outro um esquema misto de reforçamento positivo e punição negativa (adição ou remoção de tokens, respectivamente). A variável independente foi a exigência de determinado número de respostas de girar a roda para liberação de 1ml de sacarose (preço unitário), sendo a variável dependente a alocação de respostas entre os dois esquemas concorrentes. Todos os sujeitos estabeleceram distribuições estáveis de respostas (analisados como pacotes de respostas) entre os dois esquemas, os quais variaram em função do preço unitário. Os resultados confirmaram que os LEDs tiveram função de estímulo discriminativo, mas não foram claros sobre a sua função punitiva quando removidos contingente à resposta. Consequentemente, os dados obtidos não permitiram que se concluísse sobre as hipóteses testadas. Os resultados foram então analisados por três modelos explicativos do comportamento de escolha: melioração, maximização e satisficing. O modelo de satisficing foi o que produziu a melhor explicação das escolhas molares de todos os sujeitos, sob todos os preços unitários. O modelo de melioração ofereceu explicações adequadas para três sujeitos, especialmente quando o preço unitário era baixo, enquanto o de maximização foi adequado na condição de preços unitários altos, mas apenas para dois sujeitos / The objective of this study was to test the hypotheses of symmetry and asymmetry between reinforcement and punishment using an analysis that stems from behavioral economics. Five Sprague Dawley rats were used, submitted to a behavioral chain maintained by a token economy. The operant chamber had two response wheels and a lever: wheelspinning responses produced tokens (LEDs) and lever-presses exchanged tokens for sucrose. The token-production link was a concurrent condition: a positive reinforcement (token production) schedule, and a mixed schedule with a positive reinforcement and a negative punishment component (token production and removal, respectively). The independent variable was unit price, that is, the number of wheel-spins required to produce 1 cc of sucrose; the dependent variable was response allocation between the two concurrent schedules. All subjects established stable response distributions (considered as response packages) between the two schedules, which varied according to unit prices. The results confirmed that the LEDs acted as discriminative stimulus, but were not clear as to their punitive function when removed, response-contingently. Therefore, the results did not support any conclusion about the tested hypotheses. They were then analyzed based on three choice models: melioration, maximization, and satisficing. The satisficing model produced the most comprehensive explanation of molar choices among all subjects and unit prices. The melioration model produced adequate explanations for three subjects, mostly when unit prices were low, while maximization was adequate in the condition when unit prices were high, but only for two subjects
