In both field theories of high energy physics and field theories of condensed matter theories anomalies have been imposing constraints and bringing up new theories. While the perturbational and local anomalies from triangle diagrams are well-developed, we follow and review two works leading to non-perturbational global anomalies both related with Atiyah-Patogi-Sieger (APS) index theorem. In the context of topological fieldtheories the APS index theorem imposes an η-invariant which adds a global anomalous e−iπη/2 to the path integral from each fermions on the boundary. In the case of Pin+ (4) this will require a multiple of 16 Majorana fermions for the global anomaly to cancel. On the other hand with Dai-Freed theorem, global ’t Hooft anomalies concerned to G symmetry group on 4-dimensional spin manifold which is also classifying space BG are studied. The existence of anomalies are related to the triviality of spin bordismgroup Ω Spin5(BG), where examples with SU(2), GSM and Zn are studied with Atiyah-Hirzebruch spectral sequence method and representation of Z n rings. Further there are extensions of spin groups from Pin, SpinZ4 and Spinc , where the anomaly cancellationconstraint of 16 fermions per generation from Spin Z 4 (4) is related to that of Pin + (4) in topological superconductor. A possible candidate of Z4 charge named B − L charge or X charge from several commutative breaking patterns of Spin(10) GUT is briefly discussed with Pati-Salam model and R ⊗ C ⊗ H ⊗ O.

Dans la récente théorie des grounds, Prawitz développe ses investigations sémantiques dans la direction d’une analyse de l’origine et de la nature du pouvoir que les inférences valides exercent sur des agents engagés dans l’activité déductive ; à savoir, le pouvoir d’obliger épistémiquement à accepter les conclusions, si l’on en a accepté les prémisses. Un ground est ce dont on est en possession lorsqu’on est justifié à affirmer un certain énoncé. Les grounds peuvent être construits en accomplissant des opérations qui permettent le passage d’un état de justification à un autre. Un acte d’inférence consiste à l’application d’une opération sur les grounds. La théorie des grounds présente des avancements indubitables par rapport à la précédente approche de Prawitz, la proof-theoretic semantics. En particulier, la théorie des grounds offre une définition du concept d’inférence valide en vertu de laquelle il devient possible de faire dépendre la contrainte épistémique des démonstrations de celle des inférences valides dont ces démonstrations se composent. Mais théorie des grounds et proof-theoretic semantics partagent un problème ; dans l’une comme dans l’autre, inférences valides et démonstrations pourraient être telles qu’il est impossible, pour des agents qui les utilisent, de reconnaître le fait qu’elles justifient leur conclusion. Nous allons développer le cadre formel de la proposition de Prawitz en introduisant un « univers » de grounds et opérations sur grounds, ainsi que des langages et des systèmes formels de grounding. Ensuite, nous nous occupons de deux questions : celle de la complétude de la logique intuitionniste, et celle de la reconnaissabilité<br>In his recent theory of grounds, Prawitz develops his semantic investigations towards an analysis of the epistemic power which valid inferences are endowed with to compel one to accept the conclusion, provided one is justified in holding the premises true. A ground is what one is in possession of when one is justified in asserting a sentence. Grounds are built by performing operations that allow to pass from an evidence state to another evidence state. An inferential act consists of an application of an operation on grounds. The theory of grounds allows for undoubted advancements with respect to Prawitz's previous proof-theoretic semantics. In particular, it provides a definition of the notion of valid inference which makes the epistemic power of proofs depend on the epistemic power of the valid inferences of which proofs are built up. But the two semantics also share a problem; in both of them, valid inferences and proofs might be such that it is impossible, for agents who perform them, to recognize that they justify their conclusions. We develop the formal framework of Prawitz's proposal, by introducing a "universe" of grounds and operations on grounds, as well as some formal languages and systems of grounds. Then, we focus on two issues: the completeness of intuitionistic logic, and the aforementioned recognizability problem

This descriptive essay aims to develop constructivist Role theory. Specifically, it examines the potential of applying role analysis to a case of two types of actors; marginalized citizens and their state decision makers. There has previously been little role analysis applied to domestic political settings, as opposed to internationally between states. Therefore, research has been encouraged in this area. The selected empirical case is the controversial Bakun hydroelectric dam project in Sarawak, Malaysian Borneo. It involves the resettlement of the marginalized indigenous Orang Ulu people and is driven by the Sarawak state government. By analyzing the role conceptions and norms of these actors, together with the concept of power, a new perspective on their relationship is developed. The successful application of Role theory in this new setting and case is a contributing point of the study. The role analysis is conducted using a qualitative critical text analysis method; an analytical framework is established with which the actors’ roles are retrieved from the text material. The results are then analyzed, and the conclusion of the case study is that the actors have incoherent conceptions of their roles and norms, leading to a conflict between the two in which the government has the upper hand due to (illegitimate) power structures.

This dissertation uses a case study of the recently proposed dam on the Mary River at Traveston Crossing in South-East Queensland to consider how individuals can become empowered to effect change in the environmental decision-making processes of the state through citizen action in the public sphere. The theoretical framework chosen to guide the analysis is an adaptation of Judith Butler’s theory of performativity (1997) that I refer to as political performativity. I also draw on social movement theory and media theory to examine how the processes of performativity help explain the practices involved in the public sphere actions taken to stop the Queensland Government’s proposed dam. The case study demonstrates that the initial speech acts of the state government’s announcement, and the way in which these were carried out, impacted on the life worlds of people involved. The protesters’ actions were not only symbolic of their struggle but also part of the creation of an alternative life world vastly different to that imposed upon them through the various speech acts of the Queensland Government. Lessons for the future include the development of more conscious strategies for activists in public sphere actions. Potential research resulting from this study includes a closer examination of the relationship between speech acts, emotions and public sphere action. The usefulness of political performativity in understanding emotions, public sphere action and power may better be served through participatory research methodologies. Further research directions are outlined.<br>Thesis (PhD Doctorate)<br>Doctor of Philosophy (PhD)<br>School of Humanities<br>Arts, Education and Law<br>Full Text

Adult day care centres provide a means whereby frail or disabled older people can remain living at home particularly when their family care-givers engage in waged work. In Taiwan, adult day care services appear to meet the cultural needs of both older people and their families for whom filial care is vital. Little research attention has been paid to the use of day care services in Taiwan, the uptake rate of which is low. This grounded theory study explored the ways in which older people and family care-givers construct meanings around the use of day care services in Taiwan. Forty-four semi-structured interviews were undertaken with older people, care-givers and day care centre managers. The findings from grounded theory data analysis bring focus to the assumptions and structures that underpin the process of transition to day care services. A key feature of this process is the reconstruction of personal identity as both the older people and family care-givers work to make sense of the relationship between the self and a changing social structure. Reconstructing identity in a shifting world is the core category of the study and reflects a process of reframing whereby older people came to new definitions of social responsibility and independence within the context of the day care centre. Similarly, the family care-givers actively reformulated the concept of filial piety as they interacted with and interpreted the changes in economic and social conditions in Taiwan.

<p>Question:</p><p>"Does the market possess perfect information as the efficient market hypothesis says?"</p><p>"Is there any significant relationship between the abnormal stock return on the ex – day and the dividend?" Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex – day and try to figure out if abnormal returns occur on the portfolio during dividends.</p><p>Methodology:</p><p>The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 – 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days. Theory: Leading theories in this field of study have been picked to enlighten and analysis the questions of the study. Theories used: Efficient market hypothesis, agent theory and the events of dividends.</p><p>Empiricism / Results:</p><p>The authors made an event study and hypothesis tested the information. From the data they could see a small abnormal return on every day except the day after the ex – day. However, they could not prove a significant relationship between the stocks return and the dividend.</p><p>Conclusion / Discussion:</p><p>The efficient market hypothesis was strengthened in the conclusion where all new information is reflected in the stock price because the null hypothesis was accepted in all nine cases. The authors also concluded that although they have a differentiated result compared to other studies, it could be a result of the recession. Another conclusion was that the relationship between shareholders and the management has been improved because of a better spread of information.  </p>

Neste trabalho estudamos um pouco de Teoria dos Grafos, abordando diversas definições e teoremas interessantes. Apresentamos o Teorema das Quatro Cores, desde o surgimento do problema com Francis Guthrie. Analisamos a demonstração do teorema realizada por Alfred Bray Kempe e sua refutação através do contraexemplo de Percy John Heawood. Analisamos também a demonstração do Teorema das Cinco Cores de Percy John Heawood. Porém, apresentamos a primeira demonstração válida do Teorema das Quatro Cores, como sua particularidade de ter sido feita com o auxílio de um computador. O trabalho é concluído com uma análise sobre os benefícios que o conhecimento de Teoria dos Grafos pode render aos alunos do Ensino Básico, e como professor o pode trabalhar este assunto em sala de aula, inclusive abordando o problema de coloração de mapas.<br>In this paper we study Graph Theory, addressing various definitions and interesting theorems. We present the Four Color Theorem, since the origin of the problem with Francis Guthrie. We analyze the proof of the theorem presented by Alfred Bray Kempe, and its refutation by Percy John Heawood counter-example. We also analyze the Percy John Heawood demonstration of the Five Color Theorem. Finally, we present the first valid proof of the Four Colors Theorem, with its peculiarity of having been done with the aid of a computer. We conclude with an analysis of the beneficial that the knowledge of Graph Theory can render students of Basic Education, and how a teacher can work this topic in the classroom, including addressing the problem of map coloring.
