Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A presente dissertação tem por objeto o tema da negatividade ontológica constitutiva da existência humana na obra Ser e Tempo de Martin Heidegger. Na primeira parte é analisada as descrições efetuadas por Heidegger na primeira seção de Ser e Tempo sobre a dinâmica existencial do homem compreendido como ser-aí (Dasein). Nesse primeiro momento é evidenciado o caráter negativo da existência. Para tanto, partiremos da reconstrução dos conceitos de existência e deu seu caráter intencional e poder-ser (Seinkonnen) em Ser e Tempo. Na segunda parte, a análise da tonalidade afetiva da angústia é o ponto de partida para se chegar ao modo de ser do homem, descrito por Heidegger como cuidado (Sorge). Argumentaremos também, que o cuidado é o único modo de ser compatível com um ente que em seu modo de ser mais próprio é marcado por uma negatividade (incompletude) radical. Por último, em nosso terceiro capítulo, apresentaremos, em seus traços gerais, a possibilidade compatível com o caráter de poder-ser do ser-aí: a possibilidade da morte, compreendida ontologicamente como ser-para-a-morte. Na conclusão, apontaremos o interesse maior de Heidegger em investigar a dinâmica existencial do ser-aí. Esse interesse consiste, em visualizar, por meio do que Heidegger chama de crise existencial do ser-aí (proporcionada pela angústia) o ponto de gênese das ontologias. / The present dissertation aims the theme of ontological negativity constitutive of human existence in the work Being and Time of Martin Heidegger. In the first part, we examine the descriptions made by Heidegger in the first section of Being and Time about the dynamics of the existential man understood as being-there (Dasein). Initially is shown the negative character of existence. To do that, we start with the reconstruction of existence concepts and its intentional characteristcs and able to be (Seinkonnen) in Being and Time. In the second part, the analysis of the affective tone of anguish is the starting point to get to the mode of being of man, described carefully by Heidegger (Sorge). We also argue that caution is the only way to be compatible with an entity that in its own way of being is marked by an radical negativity (incomplete). Finally, in the third chapter, we present, in its general features, the possibility compatible with the character of able to be of the being-there: the possibility of death, ontologically understood as being-for-death. In the conclusion, we pointed the greatest interest of Heidegger in his investigation of existential dynamics of the being-there. This interest consist in to visualize, through what Heidegger calls of existential crisis of being-there (provided by the anguish) the genesis point of the ontologies.

The Correct Response Negativity (CRN) is an event-related potential component that is affected by the act of deception. However, there have been inconsistent findings on the effect of deception on the CRN. Suchotzki, et al. (2015) suggested that the design of the paradigm used to elicit the deceptive response is what controls the size of the CRN. Specifically, motivation to deceive changes the size of deception relative to telling the truth. This study attempted to follow up on suggestions made by Suchotzki et al. (2015) to investigate if extraneous motivation to lie does indeed invert the ratio of CRN in lie compared to truth responses in a deception experiment by manipulating the motivation to lie. This study used a modification of the image-based guilty knowledge test (GKT) paradigm used in Langleben et al. (2002). The first hypothesis of this experiments was that a larger CRN during deception relative to truth-telling will be observed when participants are not motivated to lie, while a larger CRN during truth-telling relative to deception will be observed when participants are motivated to lie. The hypothesis was not supported. The second hypothesis of this experiment was that the P300 component would be larger when participants were motivated to lie, as compared to when they were instructed to lie. Results indicated that P300 was significantly higher in the lie conditions than in the truth conditions; however, there was no difference in amplitude as a function of whether they were in the informed or motivated lie condition.

The artist discusses the work for his Masters of Fine Arts exhibition, Mind under Matter, held at the Tipton Gallery in downtown Johnson City, Tennessee. Exhibition dates are from March 27th through April 5th 2017. ‘Matter under Mind’ explores the balance of control and non-control within the art-making process. This technique creates an automatic dialogue resulting in abstraction guided by the subconscious. The title ‘Matter under Mind’ is a slight play on the phrase ‘mind over matter’ emphasizing how matter/material is manipulated by the mind through the making of artwork, and within the mind’s eye or imagination. The video installation featuring the work is accompanied by a soundscape to bring the viewer deeper into the creative process. The video symbolizes the idea of ‘solve et coagula’ or, dissolve and coagulate, destroy to recreate by revealing how the process of cleaning paint off of a surface creates artwork in itself.

A mismatch negativity response (MMN) and a new differential waveform were derived in an effort to evaluate a neural refractory or recovery effect in adult listeners. The MMN was elicited using oddball test runs in which the standard and deviant stimuli differed in frequency. To derive the differential waveform, the same standard and deviant stimuli were presented alone. MMN responses were obtained by subtracting the averaged responses to standards from the deviants. The differential waveforms were obtained by subtracting the averaged responses to standards presented alone from deviants presented alone. Scalp topography for the MMN and differential waveforms were similar.

Optimal decision-making entails outcome evaluation, comparing received costs and benefits with predicted costs and benefits. The anterior cingulate cortex (ACC), a brain area with major connections to the appetitive and aversive motivation systems, may provide the neural substrate of this evaluation process. One way to measure the relative contribution of these systems on decision-making is to measure individual differences in risk-taking behaviors. For individuals who make risky choices, this evaluation step may be biased: some show a preference for immediate, short-term rewards (increased appetitive system), while devaluing the long-term consequences of their choices (decreased aversive system). However, most studies supporting this theory have utilized monetary loss as the punishment. Other punishments that represent the presence of an aversive outcome, such as delivery of a painful stimulus, may be processed in a separate brain area and thus, may have differing effects on decision-making. The current study aimed to answer two main questions. First, we asked: is the ACC engaged by both appetitive stimuli and aversive stimuli? To answer this question, we recorded the Feedback-Related Negativity (FRN) response, a component thought to represent activity of the ACC, during a passive reward and punishment prediction task. Results indicated that the FRN responded to whether the outcome was A) unexpected and B) delivered or withheld, but not to the valence of the outcome. Second, we asked: do individual differences in these two systems have a differential impact on decision-making? To answer this question, participants completed a gambling task where they had to choose between large and small bets based on a probability of winning while we recorded their FRN response. They also completed self-report questionnaires indicating their sensitivity to reward/punishment and risk-taking behaviors. Results indicated that increased sensitivity of the appetitive system and decreased sensitivity of the aversive system (measured by both self-report and ERPs) predicted risky choice on the self-report measure and less so on the behavioral measure. Taken together, these results complement those that suggest the ACC is involved in evaluating both costs and benefits and may be influenced by both appetitive and aversive motivational systems.

The aim of this dissertation is to investigate the theoretical views underlying Karl Vennberg's literary criticism, and then to use these views as a starting point for a study of his poetry. Thus, the book is largely divided into two parts. The first deals with Vennberg's reviews and essays, the second with his poetry. As a critic and a modernist poet, Vennberg defends the autonomy of literature, but not from the organicist or aestheticising viewpoint common to post-romantic poetics. Instead, he brings to the fore another part of the heritage from romantic literary theory: the view of literature as ironic, critical and endlessly open. In his concept of irony as an endlessly ambiguous negativity, we encounter an understanding of literature that permeates all of his work. Poetry is, thus, defined by him as a freedom in relation to everything decided - a critical, destructive force that questions ingrained ideas, concepts and ideologies in the name of nothing more than negation. This theoretical stand also characterises Vennberg's relation to mysticism. He obviously feels affiliated to it's negative, critical side, it's via negativa, but does not accept the dialectics through which it reappropriates negativity into religious belief. The final part of the dissertation consists of close readings of specific poems, brought into relief by the theoretical context found in Vennberg's critical writings.

Relying mainly on R. B. Pippin’s and D. Moggach’s interpretative works on Kant and Hegel, the thesis tackles the problem of the reception of Kant by Hegel. It does so by looking into the impact of Kant’s first critique on the Preface, the Introduction and the first part of the section Self-consciousness of the Phenomenology of Spirit. Three Kantian conditions for there to be freedom are identified and shown to be reinterpreted by Hegel in a continuist perspective. These three conditions are spontaneity, reflectivity and negativity which propels and retains the free Kantian subject in the Hegelian becoming of reality.

In this study, I examine the effects of audit guidance and estimation uncertainty on auditors’ confirmation bias and professional skepticism when evaluating fair value estimates. Fair value estimation is becoming more prevalent in financial reporting frameworks, and regulators warn that fair value estimation presents higher risk of material misstatement when greater judgment in estimation is involved. In addition recent evidence from the Public Company Accounting Oversight Board (PCAOB) indicates that some auditors may not be exercising sufficient professional skepticism when performing audit procedures in higher risk areas of the audit. Martin et al. (2006) suggest that it may be the audit standards themselves that orient auditors toward biased evaluation of management’s estimates, suggesting that such directional audit guidance leads to confirmation bias. Further, it is possible that because of auditors’ intolerance for ambiguity, that a greater degree of estimation uncertainty exacerbates the bias. Thus, I examine whether directional audit guidance (e.g., support management’s estimate, and oppose management’s estimate) versus non-directional audit guidance (e.g., develop own estimate) affects auditors’ confirmation bias differentially under varying degrees of uncertainty (e.g., low vs. high), and the extent to which this bias increases or decreases professional skepticism. The results show that auditors exhibit the greatest confirmation bias when they are directed to oppose versus support management’s estimate or generate their own estimate, and that this bias increases the degree of professional skepticism exercised by auditors. Further, the greatest extent of confirmation bias resulted when auditors were directed to oppose management’s estimate and estimation uncertainty was high. This study sheds light on the effects of directional versus non-directional audit guidance in the presence of uncertainty and should be informative to standard setters and practitioners as they press forward in issuing new audit guidance related to the evaluation of fair value estimates.

This dissertation explains how and under what conditions voters are affected by campaign advertising, taking particular account of the conditioning role played by political knowledge and ad tone. It builds on psychological research showing that people make regular mistakes in attribution, evaluation, and decision making; that they tend to give greater weight to negative than to equally credible positive information; that they better match their political choices with their interests and values when they are more politically knowledgeable; and that cognitive shortcuts cannot fully compensate for meager political knowledge. I introduce a psychological theory of how individuals react to campaign advertising in light of: (1) their political knowledge and (2) their natural impulse to give greater weight to negative information (i.e., negativity bias). Using data from an original laboratory experiment conducted in Mexico City in 2012 and from the 2006 Mexico Panel Study, I examine the effect of campaign advertising on the attribution of candidates' character traits, the evaluation of candidates' policy proposals, and vote intentions. I show that campaign advertising's effects on the attribution of candidates' character traits and the evaluation of their policy proposals are conditioned by the voter's degree of political knowledge and the ad's tone (negative or positive). I also show that campaign advertising has a significant, indirect effect on vote intentions through its effect on the attribution of candidates' character traits and the evaluation of their policy proposals. Finally, I explain why negative advertising has systematically bigger effects on voting behavior than equivalent positive advertising. I look at the case of Mexico to shed light on the effects of campaign advertising in developing democracies. Since most academic research has looked at the United States, this thesis intends to deepen our understanding of campaign advertising in comparative perspective, looking at a country where the thinness of party identification, the ambiguity of issue ownership, and the novelty of the party system renders voters more susceptible to information in campaign advertising. / text
