Opérateurs de typage non-idempotents, au delà du lambda-calcul / Non-idempotent typing operators, beyond the lambda-calculus

Vial, Pierre 07 December 2017 (has links)
L'objet de cette thèse est l'extension des méthodes de la théorie des types intersections non-idempotents, introduite par Gardner et de Carvalho, à des cadres dépassant le lambda-calcul stricto sensu.- Nous proposons d'abord une caractérisation de la normalisation de tête et de la normalisation forte du lambda-mu calcul (déduction naturelle classique) en introduisant des types unions non-idempotents. Comme dans le cas intuitionniste, la non-idempotence nous permet d'extraire du typage des informations quantitatives ainsi que des preuves de terminaison beaucoup plus élémentaires que dans le cas idempotent. Ces résultats nous conduisent à définir une variante à petits pas du lambda-mu-calcul, dans lequel la normalisation forte est aussi caractérisée avec des méthodes quantitatives. - Dans un deuxième temps, nous étendons la caractérisation de la normalisation faible dans le lambda-calcul pur à un lambda-calcul infinitaire étroitement lié aux arbres de Böhm et dû à Klop et al. Ceci donne une réponse positive à une question connue comme le problème de Klop. À cette fin, il est nécessaire d'introduire conjointement un système (système S) de types infinis utilisant une intersection que nous qualifions de séquentielle, et un critère de validité servant à se débarrasser des preuves dégénérées auxquelles les grammaires coinductives de types donnent naissance. Ceci nous permet aussi de donner une solution au problème n°20 de TLCA (caractérisation par les types des permutations héréditaires). Il est à noter que ces deux problèmes n'ont pas de solution dans le cas fini (Tatsuta, 2007).- Enfin, nous étudions le pouvoir expressif des grammaires coinductives de types, en dehors de tout critère de validité. Nous devons encore recourir au système S et nous montrons que tout terme est typable de façon non triviale avec des types infinis et que l'on peut extraire de ces typages des informations sémantiques comme l'ordre (arité) de n'importe quel lambda-terme. Ceci nous amène à introduire une méthode permettant de typer des termes totalement non-productifs, dits termes muets, inspirée de la logique du premier ordre. Ce résultat prouve que, dans l'extension coinductive du modèle relationnel, tout terme a une interprétation non vide. En utilisant une méthode similaire, nous montrons aussi que le système S collapse surjectivement sur l'ensemble des points de ce modèle. / In this dissertation, we extend the methods of non-idempotent intersection type theory, pioneered by Gardner and de Carvalho, to some calculi beyond the lambda-calculus.- We first present a characterization of head and strong normalization in the lambda-mu calculus (classical natural deduction) by introducing non-idempotent union types. As in the intuitionistic case, non-idempotency allows us to extract quantitative information from the typing derivations and we obtain proofs of termination that are far more elementary than those in the idempotent case. These results leads us to define a small-step variant of the lambda-mu calculus, in which strong normalization is also characterized by means of quantitative methods.- In the second part of the dissertation, we extend the characterization of weak normalization in the pure lambda-calculus to an infinitary lambda-calculus narrowly related to Böhm trees, which was introduced by Klop et al. This gives a positive answer to a question known as Klop's problem. In that purpose, it is necessary to simultaneously introduce a system (system S) featuring infinite types and resorting to an intersection operator that we call sequential, and a validity criterion in order to discard unsound proofs that coinductive grammars give rise to. This also allows us to give a solution to TLCA problem #20 (type-theoretic characterization of hereditary permutations). It is to be noted that those two problem do not have a solution in the finite case (Tatsuta, 2007).- Finally, we study the expressive power of coinductive type grammars, without any validity criterion. We must once more resort to system S and we show that every term is typable in a non-trivial way with infinite types and that one can extract semantical information from those typings e.g. the order (arity) of any lambda-term. This leads us to introduce a method that allows typing totally unproductive terms (the so-called mute terms), which is inspired from first order logic. This result establishes that, in the coinductive extension of the relational model, every term has a non-empty interpretation. Using a similar method, we also prove that system S surjectively collapses on the set of points of this model

Botshabelo : The Symbiosis Between the Land and the People

Janeke, Anita January 2018 (has links)
Hidden, 12 km from Middelburg, lies the historic mission village Botshabelo. Named Botshabelo, meaning “place of refuge” in the Pedi language as a symbol of a place that became a refuge for the people who fled from Sekhukhune land because of their faith. Within 10 years of its establishment, Botshabelo was self sustainable and it served as a trading post throughout the surrounding farmlands. Education was also seen as one of the driving factors behind the success of Botshabelo, however, the education system was severely affected by the Bantu Education Act, implemented in the 1950s. The apartheid legislation had many negative effects on Botshabelo, whose population predominantly consisted of Bapedi and Bakopa people, and eventually led to the forced removal of 100 families from the site. The site was then turned into an open air museum. In 2005 the families who were forcibly removed won a land claim in relation to Botshabelo and since then the site has been unused and its future is still uncertain. This dissertation addresses the reintroduction of the Botshabelo Community Trust1 to the site, thereby creating a new narrative for the site, while evoking memories of the past. The intention of this project is to protect Botshabelo’s value for the future, while creating continuity of experience between the past, present and future by using its narrative as a research method. / Versteek 12km buite Middelburg lê die historiese sendingdorpie Botshabelo. Benoem “Botshabelo, plek van toevlug” ‘n simbool van ‘n plek van toevlug vir die mense wat van Sekhukhune-land gevlug het weens hul geloof oortuiging. Binne 10 jaar van sy vestiging was Botshabelo selfonderhoudend en het dit ‘n soort handelspos geword in die omliggende omgewing. Onderwys was ook gesien as een van die bestuursfaktore wat die sukses van Botshabelo behels, maar die onderwysstelsel is ernstig benadeel deur die Wet op Bantoe-onderwys, wat in die 1950’s geïmplementeer is. Die apartheidswetgewing het baie negatiewe gevolge vir Botshabelo gehad, waarvan die bevolking oorwegend bestaan uit die Bapedi- en Bakopa-mense, wat uiteindelik gelei het tot die gedwonge verwydering van 100 gesinne van die terrein. Die werf is daarna in ‘n opelugmuseum omskep, maar in 2005 het die gesinne wat tydens die Apartheid era verwyder is, ‘n grondeis in verband met Botshabelo gewen. Sedertdien is die terrein ongebruik en die toekoms daarvan is nog onseker. Hierdie proefskrif handel oor die hervestiging van die Botshabelo gemeenskap na die terrein, met die skep van ‘n nuwe narratief vir die terrein, wat herinneringe uit die verlede terugroep. Die bedoeling van hierdie projek is om Botshabelo se toekomstige waarde te beskerm. Deur gebruik te maak van n narratief navorsings metode is kontinuïteit van ervaring tussen die verlede, hede en toekoms geskep. / Mini Dissertation MArch(Prof)--University of Pretoria, 2018. / Architecture / MArch(Prof) / Unrestricted

The drivers of productive organisational energy

Lamberti, Hayden 30 April 2011 (has links)
A key-­‐contributing factor for the performance of organisations,specifically in a knowledge worker environment, is organisational energy. Defined as an exhaustible and rechargeable cultural asset; organisations with high levels of productive organisational energy display intense, positive emotions, high attention and strong activity levels that are oriented towards the company’s key strategic goals. This research aims to explicitly model the components and drivers of productive organisational energy. A qualitative investigation was used to develop constructs with which to measure productive organisational energy. These constructs were then used to create a quantitative research tool in order to determine the components and drivers of productive organisational energy. Quantitative data was gathered from 219 knowledge workers from a broad range of business sectors. Factor analysis and multiple regression testing were then used to review and empirically quantify the components and driving factors of productive organisational energy. In sharp contrast to the prevailing literature, the empirical evidence from this study shows that the components of productive organisational energy can be defined in two factors, one specifically focused on the individual and the second focused on the organisational whole. The independent drivers of these components can be broadly divided into five key areas with only three and four statistically significant factors influencing two defined components of productive organisational energy respectively.

Empirical Meaning and Incomplete Personhood

Maas, Steven M. 11 June 1998 (has links)
Both intensional and extensional explanations of linguistic meaning involve notions -- linguistic roles and referential relations, respectively -- which are not perspicuous and seem to evade satisfactory explanations themselves. Following Sellars, I make a move away from semantic explanation of the designation relation and of linguistic roles toward an explanation which relates to the use of linguistic and perceptual signs (i.e., pragmatics). In doing so, concerns are raised that seem to be more closely associated with epistemology and phenomenology than with the philosophy of language or logic. In particular, experience is taken to be intentional, i.e., to have a propositional content which is irreducible to the causal order. Along with intentionality, certain essentially autobiographical conditions of experience are neglected in typical conceptions of the problem of meaning. They are reintroduced here. Further, I take as a presupposition the pragmatist notion that each of our conceptual schemes emerges from a community of persons, rather than from individuals. What follows from the preceding starting points is a picture of incomplete personhood in which persons are seen as being inclined both toward experiential wholes which have conceptual content and toward establishing and unifying beliefs which resolve doubts. Because of the conditions of experience constitutive of, and peculiar to, personhood and the necessity of the community for individual inquiry, the notion of incomplete personhood has a central position in my pragmatist conception of the problem of meaning. By emphasizing the pragmatistic conditions of experience and the active role of persons in finding objects and in continually reaching toward a final complete picture, the problems related to objectivity are found to be peripheral to a conception of meaning which captures the practice(s) of persons' living object-directed lives. The result is a new way of conceiving of the problem of meaning. / Master of Arts

Understanding Challenges of Online Group Chat for Productive Discourse at Scale

Pasad, Viral Shrikant 14 September 2020 (has links)
Group chat facilitates remote collaboration and idea exchanges. With the widespread use of group chat for productive information exchanges, it becomes dicult for members of groups to keep up and stay grounded during the long stream of conversation that is generated. I conducted a need-finding study where I simulated group chat conversations in the context of collaboration to learn about issues and behaviors in a group chat when the size of the group chat is 5 or 10. The study participants also filled out a survey post the group chat, describing their challenges and issues with the group chat. A grounded theory approach analyses of the data collected, and the chat conversation gave us several themes. Our results show that participants generally felt that there were too many messages. A majority of the participants found it was hard to keep track of what was happening. Information overload is a significant challenge that creates several other challenges for the participants, such as missed messages, redundant messages, wasted e↵orts, and diculty in gathering consensus. I observed some behaviors such as broken utterances and other strategies employed by participants when overwhelmed with the high activity. I use this knowledge to motivate recommendations and suggestions for future redesigns and development of this indispensable tool of the workforce / Master of Science / Group chat facilitates remote collaboration, idea exchanges.

The Productive Success and Productive Failure Beliefs and Practices of Outdoor Educators

Riley, Michael Jason January 2016 (has links)
This study investigated the success and failure beliefs, instructional practices, and personal learning preferences of outdoor adventure education (OAE) instructors, and explored factors that influenced these beliefs, practices, and preferences. While statistical analysis did not show significant differences among the various demographic categories on success beliefs, instructional practices, or personal learning preferences, there were significant differences in the magnitude of reported failure beliefs. Results from this study showed that OAE instructors' age, their professional experience, their employer, and the activities they teach affect their failure beliefs. Furthermore, OAE instructors indicated that success instructional techniques, like implementing scaffolding, should be used at the onset of a course or when a new skill is being introduced, while failure techniques should be employed as students gain experience or as a perception check to assess competence. The implications of these findings for OAE instructors is discussed.

No. of bitstreams: 1 Jose Eduardo Amato Balian.pdf: 1924233 bytes, checksum: da9e7973d4718a47042467aebf6e4122 (MD5) Previous issue date: 2017-09-15 / This doctoral thesis had as its proposal the analysis of local Productive Arrangements of the confectionery sector in the cities of Cerquilho and Tietê and its socioeconomic impacts, reflections on work relations and strategic objectives. The proposal is based on the changes of the economy, the processes of production management, the relations between capital and labor and the human relationship regarding family, professional and personal interactions. The thesis had as general objective of reflection the verification of the impact of the Brazilian crisis in the APL of Cerquilho and Tietê and its consequences in the social areas and sought to identify the externalities that directly or indirectly affected the APL. In order to meet the established objectives, the case study methodology was used, with comparative and documentary analysis, considering a survey of the data. Contributed to the decision making: monitoring research developed by Sebrae SP; Globalized enterprise management models; analysis of comprehensive and specific indicators and interviews. It can be inferred up to the present time, and in accordance with the field and documentary research currently available in the areas addressed that the hypothesis was proven, insofar as the consequences for the organizations belonging to the APL were not different from the organizations outside the APL, that is, closing, unemployment and falling GDP, with all relevant social implications. The research sought to show that the benefits generated by APL extrapolate the improvements observed within the group and gains also appear in social areas. If there is a frustration with the group, it is that the people realized that the gain could be much greater, minimizing the effects of the Brazilian crisis / Esta tese de doutorado teve como proposta realizar a análise de Arranjos Produtivos do setor de confecção nas cidades de Cerquilho e Tietê e seus impactos socioeconômicos, consequências nas relações de trabalho e objetivos estratégicos. A proposta se fundamenta nas mudanças da economia, nos processos de gestão da produção, nas relações entre capital e trabalho e no relacionamento humano quanto às interações familiares, profissionais e pessoais. A tese teve como objetivo geral de reflexão verificar o impacto da crise brasileira no APL de Cerquilho e Tietê e suas consequências nas áreas sociais. Procurou também identificar as externalidades que de forma direta ou indireta afetaram o APL. Para atender aos objetivos estabelecidos, fez-se uso da metodologia de estudo de caso, com análise comparativa e documental, considerando um levantamento de dados sucundários. Contribuíram para a tomada de decisão: pesquisa de monitoramento elaborada pelo Sebrae SP; os modelos de gestão de empresas globalizadas; análise de indicadores abrangentes e específicos e entrevistas. Pode-se inferir até o presente momento, e em conformidade com a pesquisa de campo e documental atualmente disponíveis nas áreas abordadas que a hipótese foi comprovada, na medida em que as consequências para as organizações pertencentes ao APL não foram diferentes das organizações que não parte fazem do APL, ou seja, fechamento, desemprego e queda do PIB, com todas implicações sociais pertinentes. A pesquisa procurou mostrar que os benefícios gerados pelo APL extrapolam as melhorias observadas dentro do grupo; os ganhos também aparecem nas áreas sociais. Se existe uma frustração em relação ao grupo, é que os habitantes perceberam que o ganho poderia ser muito maior, minimizando os efeitos da crise brasileira

Aglomerações produtivas e desenvolvimento local : arranjos produtivos locais da amêndoa da castanha-de-caju nos municípios de Barreira e Pacajus no Estado do Ceará

Gomes, Tereza Cristina Lacerda January 2007 (has links)
O panorama internacional do agronegócio do caju, a estrutura de mercado e o padrão tecnológico sugerem que as vantagens comparativas do Brasil podem ser potencializadas. A temática central deste estudo foi a análise da dinâmica dos fatores condicionantes do desenvolvimento econômico de arranjos produtivos locais da amêndoa da castanha-de-caju nos Municípios de Barreira e Pacajus no Estado do Ceará. A metodologia abrangeu pesquisas bibliográfica, documental e estudo de caso. Os dados primários foram coletados com questionário estruturado para gestores das empresas e semi-estruturado para representantes dos órgãos de apoio e especialistas. Os resultados permitiram concluir que a dinâmica organizacional nos APLs possui predominância de sistemas produtivos intensivos em mão-deobra e com técnicas de processamento da castanha-de-caju que minimizam os impactos da baixa qualidade da matéria-prima sobre a cadeia agroexportadora; a estratégia realizada emergente é a mais freqüente nos aglomerados; não houve promoção de eventos de capacitação pelas empresas. O aprendizado a partir de fontes internas foi percebido apenas pelo segmento agroindustrial e a geração de inovações limitada ao segmento agrícola. Quanto à adoção de inovações, foi inexpressiva nos APLs e está fortemente associada às condições socioeconômicas dos empresários. A dinâmica inter-organizacional mostrou que prevaleceram os canais de comercialização com intermediação na compra da castanha-de-caju e estruturas de coordenação híbridas. A cooperação para a venda conjunta foi verificada nos dois casos e para a compra de matéria-prima pelas agroindústrias de Pacajus. O aprendizado a partir de fontes externas teve maior expressividade que o interno e abrangeu o segmento agrícola nos dois aglomerados e, no elo agroindustrial de Pacajus. O processo de transmissão de conhecimentos foi intenso em todos os segmentos, sem regularidade e conduzido de modo informal. Os esforços conjuntos em pesquisa e desenvolvimento por parte dos agentes nos APLs se verificaram apenas no segmento agroindustrial. As inovações tiveram como principais centros de difusão as próprias fontes geradoras e empresários, e o processo ocorreu principalmente de modo informal. A interação entre os ambientes institucional e organizacional sugeriu a necessidade dos agentes repensarem as posições e condutas, para que ocorra a complementaridade entre as visões prática e técnico-científica/gerencial nos aglomerados. O estudo confirmou que quando originada e/ou fortalecida por uma ação empreendedora endógena, a aglomeração de empresas sob a forma de arranjo produtivo local contribui de modo mais expressivo para o desenvolvimento econômico, mas o apoio institucional é relevante. Os fatores críticos de sucesso para os aglomerados são as deficientes condições socioeconômicas dos empresários e as dificuldades de acesso ao crédito, sendo que em Pacajus também se observou a baixa qualidade da matéria-prima, a elevada tributação e aspectos culturais. As políticas prioritárias são de fomento financeiro para a viabilização da adoção de inovações tecnológicas, melhoria de preços para os produtos e o suprimento de matérias-primas para as agroindústrias; e capacitação, assistência técnica e acesso ao conhecimento para todos os elos da cadeia para minimizar a assimetria de informações nos APLs. / The international overview of cashew agribusiness, as well as the market structure and the technological pattern have suggested that comparative advantages of Brazil can be more powerful. The main thematic of this study was the analysis for the determinant factors dynamics of the economical development of local productive arrangements of cashew nut shelled from both Barreira and Pacajus cities, in Ceará state. The methodology embraced bibliographical researches, documental and case study. The primary data were collected with a structured questionnaire for companies’ managers and semi-structured for both representatives of the support organizations and specialists as well. The results have allowed to conclude that the organizational dynamics in APLs possesses predominance of intensive productive systems in labor and cashew nut processing techniques that minimize the impacts of the raw material low quality on agriexporter chain; the emergent accomplished strategy is the most frequent in the agglomerates; there were not companies training events. The learning from internal sources was noticed only by the agri-industrial segment and the generation of limited innovations for the agricultural segment. On the other hand, the innovations adoption was inexpressive in APLs and it is strongly associated to entrepreneurs' economical conditions. The inter-organizational dynamics has shown that the commercialization channels prevailed with intermediation in the purchase of chestnut and hybrid coordination structures. The cooperation for united sale was verified in two cases and for raw material purchase by Pacajus agri-industries. The learning from external sources had larger expressiveness than internal and it embraced the agricultural segment in both agglomerates and agri-industrial Pacajus link. The knowledge transmition process was intense in all segments, without regularity and informally led. The agents’ united efforts in research and development in APLs were verified just in the agri-industrial segment. The main innovations diffusion centers were entrepreneurs themselves generating sources and the process happened mainly in an informal way. The interaction between both institutional and organizational atmospheres have suggested agents' necessity of rethinking positions and conducts, for the complementarity to happen among practice and technical-scientific/management visions in the agglomerates. The study has confirmed that when originated and/or strengthened by an endogenous enterprising action, the gathering of companies under the form of local productive arrangement contributes in a more expressive way to the economical development, but the institutional support is also relevant. The critical success factors for agglomerates are the entrepreneurs' deficient economical conditions and the credit access difficulties, since in Pacajus itself was also observed the raw material low quality, the high government taxation and cultural aspects. The priority policies are financial fomentation for the adoption viabilization of technological innovations, products prices improvement and raw material supply for agri-industries, training, technical attendance and knowledge access for all the chain links to minimize the information asymmetry in APLs.
