Research on the influence of behavioral forces that motivate trader behavior and sentiment: A prospect theory exegesis

This study focuses on empirical investigations and seeks implications by utilizing three different methodologies to test various aspects of trader behavior. The first methodology utilizes Prospect Theory to determine trader behavior during periods of extreme wealth contracting periods. Secondly, a threshold model to examine the sentiment variable is formulated and thirdly a study is made of the contagion effect and trader behavior. ^ The connection between consumers' sense of financial well-being or sentiment and stock market performance has been studied at length. However, without data on actual versus experimental performance, implications based on this relationship are meaningless. The empirical agenda included examining a proprietary file of daily trader activities over a five-year period. Overall, during periods of extreme wealth altering conditions, traders "satisfice" rather than choose the "best" alternative. A trader's degree of loss aversion depends on his/her prior investment performance. A model that explains the behavior of traders during periods of turmoil is developed. Prospect Theory and the data file influenced the design of the model. ^ Additional research included testing a model that permitted the data to signal the crisis through a threshold model. The third empirical study sought to investigate the existence of contagion caused by declining global wealth effects using evidence from the mining industry in Canada. Contagion, where a financial crisis begins locally and subsequently spreads elsewhere, has been studied in terms of correlations among similar regions. The results provide support for Prospect Theory in two out of the three empirical studies. ^ The dissertation emphasizes the need for specifying precise, testable models of investors' expectations by providing tools to identify paradoxical behavior patterns.

The World in Singing Made: David Markson's "Wittgenstein's Mistress"

In line with Wittgenstein's axiom that "what the solipsist means is quite correct; only it cannot be said, but makes itself manifest," this thesis aims to demonstrate how the gulf between analytic and continental philosophy can best be bridged through the mediation of art. The present thesis brings attention to Markson's work, lauded in the tradition of Faulkner, Joyce, and Lowry, as exemplary of the shift from modernity to postmodernity, wherein the human heart is not only in conflict with itself, but with the language out of which it is necessarily constituted. Markson limns the paradoxical condition of the subject severed from intersubjectivity, and affected not only by the grief of bereavement, which can be defined in Heideggarian terms as anxiety for the ontic negation of a being (i.e., death), but by loss, which I assert is the ontological ground for how Dasein encounters the nothing in anxiety proper.

A constituição desmilitarizada: democratização e reforma do sistema constitucional de segurança pública

The normative construction of the public security system in the Constituent Assembly of 1987-1988 preserved paradoxical normative space, the military police linked to the Army with a restrictive legal statute of the police offices citizenship through a hierarchical and disciplinary model that is anachronistic. This research originates from the following problem: How is it possible to tailor the constitutional system of public safety, specifically the Military Police, according to the democratic paradigms constructed by the Constituent from 1988 and carry the right to public safety under these molds? The militarists limitations of the Constitution allowed the growing militarization of police departments, organizational culture and authoritarian institutional practices. Underlying this, the problems related to difficulties in realization of Right to Public Safety, the strikes of the military police, the incomplete policy cycle started demanding from the constitutional-legal system appropriate responses. Utilizing the dialogical method and an interdisciplinary approach to the subject, and theoretically grounded in overcoming of the constitutional normativist juspositivism.It was found that the constructed infraconstitutional legislation was insufficient to supply the systemic shortcomings of constitutional law, when looking to create a single system of public security without giving due scope to the federal principle and expand the autonomy the Federated States, and even grant democratic legal status to the military police. Formal legal limits imposed by the Constitution constructed a legal anachronism, the military police. Thus, a democratic reading of military police institutions becomes inconceivable its existence in the constitutional regulatory environment. Thus, reform the Constitution in order to demilitarize the police and conduct a normative redesign of the public security system is fundamental to Brazilian constitutional democracy

Fatores de virulência, resistência ao estresse osmótico e susceptibilidade de isolados de Candida tropicalis oriundos de ambiente costeiro do nordeste brasileiro

Several studies have been developed regarding health risks associated with the recreational use of beaches contaminated with domestic sewage. These wastes contain various microorganisms, including Candida tropicalis, etiologic agent of both superficial infections such as systemic, as well as indicator of fecal contamination for the environment. In this context, the objective of this study was to characterize C. tropicalis isolates from the sandy beach of Ponta Negra, Natal, Rio Grande do Norte, Brazil, regarding the expression of in vitro virulence factors, adaptation to osmotic stress and susceptibility to antifungal drugs. We analyzed 62 environmental isolates of C. tropicalis and observed a great variation between them for the various virulence factors evaluated. In general, environmental isolates were more adherent to CEBH than C. tropicalis ATCC13803 reference strain, besides the fact they were also highly biofilm producers. In relation to morphogenesis, most isolates presented wrinkled phenotype in Spider medium (34 isolates, 54.8 %). When assessing enzyme activity, most isolates had higher proteinase production than C. tropicalis ATCC13803 reference strain. In addition, 35 isolates (56.4 %) had high hemolytic activity (hemolysis index > 55). With regard to C. tropicalis resistance to osmotic stress, 85.4% of the isolates were able to grow in a liquid medium containing 15% sodium chloride, corroborating to high survival capacity described for this yeast at marine environment. Finally, with regard to sensitivity to antifungal drugs, it was observed high resistance to the azoles tested, with the occurrence of the "Low-high" phenomenon and similar effect to the paradoxical growth which occurs to the echinocandins. For the three azoles tested we verified that 15 strains were resistant (24.2 %). Some strains were also resistant to amphotericin B (14 isolates, 22.6 %), while all of them were sensitive for the echinocandins tested. Therefore, our results demonstrate that C. tropicalis isolated from the sand of northeast of Brazil can fully express virulence attributes and showed a high persistence capacity on the coastal environment, in addition of being significantly resistant to most applied antifungals in current clinical practice. This constitutes a potential health risk to visitors of this environment, especially immunocompromised individuals and those with extreme age range.

Dinocyst-derived sea-surface characteristics, palynomorph abundances, ice-rafted debris, and planktonic foraminifera abundances and d18O of the 35-41 ka BP interval of core MD99-2285

The last glacial millennial climatic events (i.e. Dansgaard-Oeschger and Heinrich events) constitute outstanding case studies of coupled atmosphere-ocean-cryosphere interactions. Here, we investigate the evolution of sea-surface and subsurface conditions, in terms of temperature, salinity and sea ice cover, at very high-resolution (mean resolution between 55 and 155 years depending on proxies) during the 35-41 ka cal BP interval covering three Dansgaard-Oeschger cycles and including Heinrich event 4, in a new unpublished marine record, i.e. the MD99-2285 core (62.69°N; -3.57s°E). We use a large panel of complementary tools, which notably includes dinocyst-derived sea-ice cover duration quantifications. The high temporal resolution and multiproxy approach of this work allows us to identify the sequence of processes and to assess ocean-cryosphere interactions occurring during these periodic ice-sheet collapse events. Our results evidence a paradoxical hydrological scheme where (i) Greenland interstadials are marked by a homogeneous and cold upper water column, with intensive winter sea ice formation and summer sea ice melting, and (ii) Greenland and Heinrich stadials are characterized by a very warm and low saline surface layer with iceberg calving and reduced sea ice formation, separated by a strong halocline from a less warm and saltier subsurface layer. Our work also suggests that this stadial surface/subsurface warming started before massive iceberg release, in relation with warm Atlantic water advection. These findings thus support the theory that upper ocean warming might have triggered European ice-sheet destabilization. Besides, previous paleoceanographic studies conducted along the Atlantic inflow pathways close to the edge of European ice-sheets suggest that such a feature might have occurred in this whole area. Nonetheless, additional high resolution paleoreconstructions are required to confirm such a regional scheme.

Contradições como força de mudança: o processo de formação continuada de professores do ensino médio enquanto potencializador da práxis transformadora à luz da teoria histórico-cultural

The intervention research proposed was based on the Cultural-Historical Theory based on the laws and logic of materialism historical-dialectical. Therefore, we tried to design a research process that involved all as responsible for the process. In the field of continuous teacher's training usually has been found dualistic relationship / paradoxical processes as a result of the adopted training models which are characterized by individualist human processes. The teacher training work sought to overcome this dualism, to promote the unveiling of the contradictions with regard to teaching models. As a hypothesis, we imagined that immersed in this process, teachers recognize such contradictions, and this recognition would make the contradictions become the driving force of change in teaching practice, realizing the teaching-learning-development triad as the basis of praxis. Aiming to develop a process of continuing education to bring results to the professional teachers development looking for answer the following research question: How and what the changes of teachers who participated in the Didactic-Formative Intervention process raised the quality of their teaching practices? In this context, the objective of the research was to develop a process of Didactic-Formative Intervention from the perspective of Cultural-Historical Theory with high school teachers in order to theorize about the changes in pedagogical practices of teachers and learn aspects that transform the essence teaching practice. The research involved two high school teachers of a public school in Uberlândia-MG. The training meetings took place at the school through a collective study group between the years 2013 and 2015. As procedures were used two interconnected aspects: classes observations, and a theoretical and methodological training, both for diagnosis and for the process evaluation, the second aspect has a formative dimension, and a didactic dimension (double meaning) to form didactically the teacher and to elaborate didactic procedures. The collected data were analyzed by observing the assumptions of the method, analysis by units and the processuality. As results teachers showed changes in their teaching practices regarding the organization of the pedagogical work and also centered their design educational actions based on learning and development of the students. The presence of continuous diagnosis during the classes, work with a systems of concepts and their conceptual links, problematization as a teaching method can be pointed as meaningful changes in their praxis. Regarding the training activities that emerged from the analysis of the compiled materials and analyzed throughout the process can be emphasized: forming a collective group of school teachers continuous training, diagnostics, development of practical activities, increase relationships among participants, the choice of scientific material used should have direct relation to the needs of the participants, promoting conditions that enable the emergence of contradictions between the pedagogical practice of teachers and teaching based on the perspective of the Cultural-Historical Theory. This research craved to develop and design a teachers' training processes that increase the quality of teachers life and ways of teaching in the Brazilian public school.

The paradoxes of risk management in the banking sector

This paper uses empirical evidence to examine the operational dynamics and paradoxical nature of risk management systems in the banking sector. It demonstrates how a core paradox of market versus regulatory demands and an accompanying variety of performance, learning and belonging paradoxes underlie evident tensions in the interaction between front and back office staff in banks. Organisational responses to such paradoxes are found to range from passive to proactive, reflecting differing organisational, departmental and individual risk culture(s), and performance management systems. Nonetheless, a common feature of regulatory initiatives designed to secure a more structurally independent risk management function is that they have failed to rectify a critical imbalance of power - with the back office control functions continuing to be dominated by front office trading and investment functions. Ultimately, viewing the 'core' of risk management systems as a series of connected paradoxes rather than a set of assured, robust practices, requires a fundamental switch in emphasis away from a normative, standards-based approach to risk management to one which gives greater recognition to its behavioural dimensions.

Making it real of sustaining a fantasy? Personal budgets for older people

The restructuring of English social care services in the last three decades, as services are provided through a shifting collage of state, for-profit and non-profit organisations, exemplifies many of the themes of governance (Bevir, 2013). As well as institutional changes, there have been a new set of elite narratives about citizen behaviours and contributions, undergirded by modernist social science insights into the wellbeing benefits of ‘self-management’ (Mol, 2008). In this article, we particularly focus on the ways in which a narrative of personalisation has been deployed in older people’s social care services. Personalisation is based on an espoused aspiration of empowerment and autonomy through universal implementation to all users of social care (encapsulated in the Making it Real campaign [Think Local, Act Personal (TLAP), no date)], which leaves unproblematised the ever increasing residualisation of older adult social care and the abjection of the frail (Higgs and Gilleard, 2015). In this narrative of universal personalisation, older people are paradoxically positioned as ‘the unexceptional exception’; ‘unexceptional’ in the sense that, as the majority user group, they are rhetorically included in this promised transformation of adult social care; but ‘the exception’ in the sense that frail older adults are persistently placed beyond its reach. It is this paradoxical positioning of older adult social care users as the unexceptional exception and its ideological function that we seek to explain in this article.

Chaucer and the Disconsolations of Philosophy: Boethius, Agency, and Literary Form in Late Medieval Literature

This study argues that Chaucer's poetry belongs to a far-reaching conversation about the forms of consolation (philosophical, theological, and poetic) that are available to human persons. Chaucer's entry point to this conversation was Boethius's Consolation of Philosophy, a sixth-century dialogue that tried to show how the Stoic ideals of autonomy and self-possession are not simply normative for human beings but remain within the grasp of every individual. Drawing on biblical commentary, consolation literature, and political theory, this study contends that Chaucer's interrogation of the moral and intellectual ideals of the Consolation took the form of philosophical disconsolations: scenes of profound poetic rupture in which a character, sometimes even Chaucer himself, turns to philosophy for solace and yet fails to be consoled. Indeed, philosophy itself becomes a source of despair. In staging these disconsolations, I contend that Chaucer asks his readers to consider the moral dimensions of the aspirations internal to ancient philosophy and the assumptions about the self that must be true if its insights are to console and instruct. For Chaucer, the self must be seen as a gift that flowers through reciprocity (both human and divine) and not as an object to be disciplined and regulated.

Chapter one focuses on the Consolation of Philosophy. I argue that recent attempts to characterize Chaucer's relationship to this text as skeptical fail to engage the Consolation on its own terms. The allegory of Lady Philosophy's revelation to a disconsolate Boethius enables philosophy to become both an agent and an object of inquiry. I argue that Boethius's initial skepticism about the pretentions of philosophy is in part what Philosophy's therapies are meant to respond to. The pressures that Chaucer's poetry exerts on the ideals of autonomy and self-possession sharpen one of the major absences of the Consolation: viz., the unanswered question of whether Philosophy's therapies have actually consoled Boethius. Chapter two considers one of the Consolation's fascinating and paradoxical afterlives: Robert Holcot's Postilla super librum sapientiae (1340-43). I argue that Holcot's Stoic conception of wisdom, a conception he explicitly links with Boethius's Consolation, relies on a model of agency that is strikingly similar to the powers of self-knowledge that Philosophy argues Boethius to posses. Chapter three examines Chaucer's fullest exploration of the Boethian model of selfhood and his ultimate rejection of it in Troilus and Criseyde. The poem, which Chaucer called his "tragedy," belonged to a genre of classical writing he knew of only from Philosophy's brief mention of it in the Consolation. Chaucer appropriates the genre to explore and recover mourning as a meaningful act. In Chapter four, I turn to Dante and the House of Fame to consider Chaucer's self-reflections about his ambitions as a poet and the demands of truth-telling.

Regionalismo estratégico : una respuesta frente a la glocalización. El desarrollo urbano posfordista en el este de Alemania

Los procesos de asociatividad territorial de una ciudad pueden derivar en proyectos de regionalización a diferentes escalas. Otrora, factores como conectividad, accesibilidad y proximidad eran imprescindibles para el posicionamiento urbano. En la actual glocalización ellos son insuficientes y dan lugar a desarrollos urbanos posfordistas. La ideología de la competitividad llevada al territorio condujo a diversos tipos de estrategias para jugar el juego de seducción al capital. La región emerge como la forma territorial que posibilita la entrada al "mercado de los lugares" que pertenecen al mundo global. La promoción de regiones es una estrategia para reforzar identidad frente a la globalización y funciona como factor para atraer actividades y población. No todas las ciudades tienen "éxito" pero la participación de agentes y la paradójica combinación de competitividad y asociatividad permiten corregir distorsiones. Aquí se aborda el caso de la ciudad-región Weimar, donde el regionalismo estratégico surge como uno de los caminos de reproducción urbana.
