The primary bibliography used was the fourth edition, dated 1906, of the Keynes‟s textbook on Logic Studies and Exercises in Formal Logic . Keynes has an extensional interpretation of the use of negative terms: they are understood as an extensional complement of the corresponding positive terms relative the universe of discourse; in this sense, his conception of the negation of terms obeys the Principle of Excluded Middle. The extension of traditional syllogistics by the addition of negative terms also leads to an extension of the number logical relations among the categorical propositions, as well as the number of valid immediate inferences. The Square of Oppositions is transformed into an Octagon of Oppositions, to which three new logical relations between the categorical propositions are added, namely, complementarity, sub-complementarity and contra-complementarity; the validity of these new logical relations does not require existential presupposition of any of the involved terms. Regarding immediate inferences, besides the conversion process, three new types of formal processes are obtained: obversion, contraposition (partial and total) and inversion (partial and total). To prove the validity of these formal processes, as well as of any syllogistic inference, Keynes lays out a diagrammatic method based on the well-known Euler method; in Keynes‟s method, however, negative terms are represented. In Keynes‟s version of Euler‟s diagrammatic method validity is understood as preservation of information: a collection of basic diagrams, corresponding to elementary information, is assigned to categorical propositions; and an inference is valid if, and only if, the diagrams assigned to the premises are also assigned to the conclusion. / Este trabalho apresenta e discute a ampliação da silogística tradicional aristotélica, realizada por John Neville Keynes no início do século XX, mediante a introdução de uma notação para termos negativos na teoria lógica. A bibliografia primária utilizada foi a quarta edição, datada de 1906, do manual de Lógica de Keynes Studies and Exercises in Formal Logic. Keynes tem uma interpretação extensional acerca do uso dos termos negativos: eles são entendidos como o complemento extensional do seu correspondente termo positivo em relação ao universo do discurso; neste sentido, a sua concepção da negação terminística obedece ao Princípio do Terceiro Excluído. A ampliação da silogística tradicional pelo acréscimo dos termos negativos leva, também, a uma ampliação do número de relações lógicas entre as proposições categóricas, assim como do número de inferências imediatas válidas. O Quadrado de Oposições é transformado em um Octógono de Oposições, no qual são acrescentadas três novas relações lógicas entre as proposições categóricas, a saber, a complementaridade, a subcomplementaridade, e a contracomplementaridade; a validade destas novas relações lógicas não exige o pressuposto existencial de nenhum dos termos envolvidos. Quanto às inferências imediatas, além do processo de conversão, três novos tipos destes processos formais são obtidos: a obversão, a contraposição (parcial e total) e a inversão (parcial e total). Para provar a validade destes processos formais, assim como de quaisquer inferências na silogística, Keynes apresenta um método diagramático desenvolvido a partir do conhecido método de Euler; no método de Keynes, porém, há a representação de termos negativos. Na versão de Keynes do método diagramático de Euler a validade é entendida como preservação de informação: uma coleção de diagramas básicos, correspondentes às informações elementares, é atribuída às proposições categóricas; e uma inferência é válida se, e somente se, os diagramas atribuídos às premissas também estão atribuídos à conclusão.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This dissertation investigates the importance of monetary policy as a regulator of the monetary and financial system and as an automatic stabilization mechanism cycles of monetary economies of production, the way Keynes and the post-Keynesian perspective, which theoretically guide this work, define the capitalist economy. Specifically, this research answer the following questions: in view of the theoretical framework of Keynes and the progress made by the post-Keynesians authors, what could be the Keynesian monetary policy regime? What characteristics, mode of operation, instruments and institutions of AM? So there will be a theoretical research on the major works of Keynes dealing with the role of money and monetary policy, as well as the contributions made by post- Keynesian authors. The conclusions of the study conceive a Keynesian monetary regime consistent with the mode of operation of monetary economies of production in the AM seeks to address three objectives, listed hierarchically: full employment, monetary stability and financial stability. To achieve these objectives, has instruments for an active monetary policy, for the reserve requirements, rediscount rate, open market operations and financial regulatory measures. Furthermore, in relation to the institutions surrounding the AM, there is the freedom that it has to operate their instruments in pursuit of the goal of general economic policy outlined by the Government, and the importance of coordination between the economic policies for the proper functioning Keynesian monetary regime. / Este trabalho investiga a importância da política monetária como reguladora do sistema monetário e financeiro e como um mecanismo de estabilização automática dos ciclos das economias monetárias de produção, modo pelo qual Keynes e a perspectiva pós-keynesiana, que norteiam teoricamente este trabalho, definem a economia capitalista. Especificamente, o trabalho busca responder às seguintes questões: tendo em vista o referencial teórico de Keynes e os avanços realizados pelos autores pós-keynesianos, o que seria o regime de política monetária keynesiano? Quais suas características, modo de funcionamento, instrumentos e institucionalidade da AM? Para tanto, realiza-se um resgate teórico das principais obras de Keynes que tratam do papel da moeda e da política monetária, assim como as contribuições realizadas pelos autores pós-keynesianos. As conclusões do trabalho concebem um regime monetário keynesiano condizente com o modo de funcionamento de economias monetárias da produção, em que a AM busca contemplar três objetivos, hierarquicamente elencados: pleno emprego, estabilidade monetária e estabilidade financeira. Para o alcance de tais objetivos ela dispõe de instrumentos para uma política monetária ativa, referentes ao recolhimento compulsório, taxa de redesconto, operações de mercado aberto e medidas de regulamentação financeira. Ademais, em relação à institucionalidade que cerca a AM, destaca-se a liberdade de que ela dispõe para operacionalizar seus instrumentos em busca do objetivo da política econômica geral, delineado pelo Governo, além da importância da coordenação entre as políticas econômicas para o bom funcionamento do regime monetário keynesiano. / Mestre em Economia

A presente tese de doutoramento é composta de três ensaios independentes (ainda que complementares) sobre a História do Pensamento Econômico, mais especificamente, da Macroeconomia. O primeiro ensaio - \"Uma Breve História sobre a Abordagem de Desequilíbrio na Macroeconomia\" - é uma versão revista e ampliada do artigo apresentado no XXXVIII Encontro Nacional de Economia da ANPEC em 2010 (Uma Breve História sobre a Abordagem de Desequilíbrio na Economia). Nossa argumentação vai de encontro às interpretações de Romer (1989) e Mankiw (2005) sobre a compreensão histórica daquele episódio, como também a hipótese levantada por Backhouse & Boianovsky (2005) sobre o fracasso da Macroeconomia do Desequilíbrio. O segundo ensaio se chama \"Uma Análise Histórica (e Retórica) do Discurso Doutrinário de Robert E. Lucas Jr.\". Se no primeiro ensaio argumentamos que parte do \"fracasso\" da Abordagem de Desequilíbrio deveu-se ao surgimento de um método entendido como superior pela maior parte dos economistas (o método de Lucas), neste investigamos o conteúdo daqueles artigos em que Lucas busca convencer os leitores da superioridade do seu método não a partir da comparação dos resultados obtidos por seu modelo em comparação a uma estrutura alternativa, mas sim com uma retórica polemista, fazendo uso de uma série de estratagemas retóricos. Nossa intenção é checar a validade de algumas de suas teses históricas e teóricas, bem como fazer um escrutínio dos expedientes retóricos utilizados pelo autor. O terceiro ensaio - \"Tese da Ancestralidade, Reinvenção da Tradição ou Superação Positiva? Uma Investigação sobre a \"Macroeconomia\" anterior a Keynes e as Causas do Sucesso da Teoria Geral\" - é derivada do segundo ensaio. Partimos da contraposição de hipóteses históricas de dois grandes autores da Macroeconomia sobre o estado da teoria \"macroeconômica\" anterior a Keynes, e as causas do sucesso da Teoria Geral. De um lado, Robert Lucas trata a Macroeconomia fundada por Keynes como um desvio na tradição equilibrista das análises de flutuação, cujo sucesso foi um \'feliz acidente histórico\', provocado principalmente por fatores alheios as vontades e até as simpatias de Keynes. De outro, Olivier Blanchard argumenta que o que havia antes de Keynes era uma grande diversidade de métodos e ausência de um aparato hegemônico, e o sucesso de Keynes deveu-se exclusivamente aos avanços teóricos e metodológicos apresentados naquela obra. / This PhD thesis contains three independent (although complementary) essays on the History of Economic Thought, more specifically on Macroeconomics History. The first essay - A Brief History of the Disequilibrium Approach in Macroeconomics - is a revised and expanded version of paper presented at the XXXVIII Meeting of ANPEC. Our argumentation challenges Romer (1989) and Mankiw (2005) interpretations about that episode. We also disagree (at some level) with Backhouse & Boianovsky (2005) hypothesis about the so-called \"failure\" of Non-Market-Clearing Approach. The second essay - A Historical (and Rhetorical) Analysis of Robert E. Lucas Junior\'s Doctrinaire Speech - is still a work in progress. If the first essay we argue that part of the \"failure\" of Disequilibrium Approach was due to the emergence of a method perceived as superior by most economists (lucasian method), here we investigate the content of those articles where Lucas seeks to persuade its readers of the superiority of his method not from the scrutiny of the results obtained by a specific model in comparison to an alternative structure, but mainly through a polemicist rhetoric. Our intention is to check the validity of some of its historical and theoretical arguments, and make a scrutiny of rhetorical expedients used by the author. The third essay - Ancestry Thesis, Reinvention of a Tradition or Cumulative Progress? A Research on \"Macroeconomics\" before Keynes and some Speculation about the causes of General Theory\'s Success\" - is derived from the second paper. We start from the juxtaposition of historical hypotheses of two great authors about the state\'s theory of \"macroeconomic\" before Keynes, and the causes of the success of the General Theory. On one hand, Robert Lucas argues that Macroeconomics as developed by Keynes was a deviation in the tradition of equilibrist fluctuation analysis, whose success was a fortunate historical accident. On the other, Olivier Blanchard argues that what was before Keynes was a great diversity of methods and the absence of a hegemonic apparatus, and the success of Keynes was due exclusively to theoretical and methodological advances made in that work.

Nous démontrons qu’il existe une récurrence dans la pensée de Keynes en matière de fluctuations, à savoir que l’investissement est le facteur majeur guidant les fluctuations économiques. La première partie explore les écrits datant d’avant 1925 environ, en analysant les thématiques et problèmes qui en émergent et qui anticipent ceux du Treatise on Money (1930). La seconde partie se focalise sur le Treatise à proprement parler, ainsi que la transition de cet ouvrage à la Théorie Générale de l’Emploi, de l’Intérêt et de la Monnaie (1936) suite à la crise économique du début des années 1930. La troisième et dernière partie aborde ainsi la réponse apportée par la Théorie Générale à ce problème, en démontrant que la théorie de l’investissement qui y est développée est au coeur de son analyse des fluctuations et cycles économiques. / The dissertation argues that there is a recurrence in Keynes’s thought as regards economic fluctuations: investment is considered as the primary factor driving these fluctuations. The first part explains how, in the author’s early writings, some topics and problems that would be discussed in the Treatise on Money (1930) would emerge out of an interest for monetary instability. The second part focuses on the Treatise as such, but also on the transition between this book and the General Theory of Employment, Interest and Money (1936) following the economic crisis of the Great Depression. Finally the third part discusses the answer given by the General Theory to this problem, by showing that investment as understood and explained in this book is at the center of an analysis of economic fluctuations and business cycles.

O objetivo deste trabalho é analisar as transformações por que passou a teoria econômica no período entre-guerras, relacionando-as às mudanças econômicas e políticas que caracterizam o capitalismo da época. O ponto de partida é o contraste realizado por Karl Polanyi entre os conservadores anos 1920 e os revolucionários anos 1930. Argumenta-se que os conflitos em tomo do restabelecimento e do posterior abandono do padrão-ouro, que representaram a tentativa de restauração do liberalismo econômico e sua subseqüente frustração, foram determinantes nas disputas políticas e teóricas do período. A obra de Friedrich von Hayek é relacionada aos conservadores anos 1920, enquanto a obra de John Maynard Keynes é associada às transformações da década de 1930. São enfatizados os contrastes entre os conceitos de equilíbrio e taxa de juros adotados pelos dois autores. Além disso, argumenta-se que as transformações da teoria econômica não se restringiram a alterações de conceitos e hipóteses, mas envolveram também um deslocamento do papel desempenhado pela teoria na reprodução da sociedade, com a emergência da gestão macroeconômica do capitalismo. / The aim of this work is to analyse the transformation that economics has been through in the interwar years, relating it to the economic and political transformation of the period\'s capitalism. The point of departure is Karl Polanyi\'s contrast between the conservative 1920s and the revolutionary 1930s. It is argued that the conflicts around the reestablishment and the abandonment of the gold-standard, which represented the attempt (and its subsequent frustration) to restore economic liberalism, exercised a great influence on the political and theoretic disputes of the time. Friedrich von Hayek\'s work is related to the conservative 1920s, while John Maynard Keynes\' work is connected with the transformations of the 1930s. The contrasts between the authors\' concepts of equilibrium and interest rate are particularly emphasized. Finally, it is maintained that the transformation of economics was not restricted to changes of concepts and hypotheses, but involved also a transformation of the role fulfilled by this theory in the reproduction of society, with the emergence of the macroeconomic management of capitalism.

Unemployment is a major problem in South Africa that has the potential to erode the democratic future of this country. In general, the main economic approaches that deal with unemployment are informed by neo-liberal and neo-Marxist perspectives. The problem is that these perspectives are in a dialectical tension with each other and can increase conflict and unemployment. This dialectical tension is reflected in language that can be informed by the reductionist aspects of the ontologies perspectives. The purpose of this study is to inquire whether the deconstruction of Jacques Derrida can provide an alternative perspective for the dialectical tension present between neo-liberal and neo-Marxist approaches that are being used to address the problem of unemployment in the South African context. In this regard, the critique of the language of reductionist ontologies by deconstruction provides a means to move beyond the tension between neo-liberalism and neo-Marxism, because deconstruction uncovers the ambivalence of the language of both perspectives, but without constructing a new synthesis that may result in new reductions of reality. This reduction of reality is evident in the use of “growth momentum”, referred to by Rodrik (2008:3), as a suggestion of a neo-liberal solution to the problem of unemployment. Growth is a reference to natural processes that can become a means to hide the mechanical structure of the economic cycle, which again has the potential to restrict growth through extreme forms of inequality and greed. Neo-Marxist perspectives utilise references to “equality” and “government intervention” to deal with injustice. This can result in extreme forms of control that diminish human dignity. The role of deconstruction for the language of economic theory is illustrated by Jacques Derrida’s use of the word “Gift”. A gift is ambivalent because it contains a tension between self-interest and justice, which Jacques Derrida refers to as “hospitable narcissism”. It will be argued that this ambivalence is present in the language of the economic theory of John Maynard Keynes, which may provide important sustainable economic perspectives for dealing with unemployment in South Africa, thus providing a practical application of hospitable narcissism. In this regard, deconstruction is helpful to develop sensitivity to the language used and the ontologies that inform the language when addressing unemployment. The gift advances human dignity through responsible governance that is critical of 5 uncontrolled self-interest, greed and corruption. This happens through engagement with unemployed people – an act of accountability. In this regard, the study aims at researching the following goals: Firstly, it aims to argue that unemployment in general is perpetuated by the dialectical tension between neo-liberalism and neo-Marxism; secondly, the deconstruction of language provides a critical perspective on reality that opens new perspectives for discussing the possibility of sustainable economic language, with reference to the word “gift”; thirdly, an aspect of “the gift” is present in the economic theory of Keynes that may provide sustainable perspectives for unemployment in the South African context. In order to reach these goals, a praxis methodology is followed in which the practical reality of unemployment and the dialectical tension between neo-liberalism and neo-Marxism in South Africa are the points of departure. The implication is that the economic reality of unemployment and the political tension between neo-liberalism and neo-Marxism form the basis for further philosophical reflection. To do this, a deconstructive approach is followed as a means to explore the ontology of neo-liberalism and neo-Marxism. This is followed by a deconstructive reading of the economic theory that John Maynard Keynes follows in order to provide alternative perspectives for the problem of unemployment in South Africa. The following resources were consulted in the research: Library catalogue of the North-West University, research articles through the database of Ebsco-host, statistics of unemployment from Statistics South Africa, and newspaper articles. This mini-dissertation is presented in the form of an article, in accordance with rule A.7.2.5 of the “General Academic Rules” of the North-West University. The article will be presented for publication in the journal Acta Academica, at a later stage. In this regard, the guidelines for publication of this journal are included in the appendix. The article contains the following subdivisions: 1. Introduction 2. Neo-liberalism and neo-Marxism: Contemporary research of unemployment in South Africa 3. Deconstruction and “the gift” 4. John Maynard Keynes and unemployment 5. “The gift” and unemployment in the South African context 6. Conclusion In the next section, the research article is presented with a bibliography and a summary of the article in English and Afrikaans, in accordance with the prescriptions of Acta Academica. In the final sections of the document some general conclusions, the limitations of the study and recommendations for further research, are presented. This is followed by the appendix with prescriptions for research articles submitted to Acta Academica. / Thesis (MPhil)--North-West University, Potchefstroom Campus, 2013.

This thesis aimed to understand the factors which shape the police and CPS response to domestic violence in the light of recent policy changes which recommended arrest in such cases. The decisions made by victims, police and prosecutors were charted in over one thousand three hundred reported cases of domestic violence in the Thames Valley during a seven month period in 1993. A random sample of 387 of these incidents were examined in detail. The study sought to understand the needs, desires and expectations of victims and how their choices impacted on the decisions made by police and prosecutors. Having evaluated feminist theories, the thesis argues that police and prosecutors do not randomly exercise their discretion nor can their response be explained by reference to cultural or individual prejudices. Rather, their decisions are best understood in terms of a set of informal 'working rules' developed by police and prosecutors for dealing with these complex and difficult cases. It is shown that whilst evidence of an offence was highly correlated with decisions regarding arrest and prosecution, evidence did not determine police action nor did its absence preclude such action. Rather, evidence facilitated police action where the working rules pointed towards an arrest. One of the strongest working rules related to the willingness of the victim to support a prosecution or not. The majority of victims did not want their partners or ex-partners to be prosecuted even when they had requested that the police arrest the perpetrators. Police and prosecutors believe the criminal justice system to be an extremely clumsy tool in dealing with domestic disputes. They therefore did not pursue independent evidence when victims withdrew their statements and they consequently discontinued these cases or did not initiate prosecution in the first place. Previous research has started from the premise that withdrawal of complaints by victims and the discontinuance of cases represents some kind of failure on the part of the agencies involved and that this would be remedied if the police arrested and prosecuted wherever possible. Implicit in this approach is the assumption that the criminal justice system as it presently operates is capable of responding effectively to the needs of victims of domestic violence. This thesis throws some doubt on the validity of these assumptions.
