Sistema de apoio à decisão na localização de peças

A globalização, nas suas diversas dimensões, está a tornar o mundo cada vez mais pequeno, alterando as nossas vidas e transformando a forma como as empresas fazem negócios. Estamos cada vez mais expostos aos traços e práticas das outras culturas à medida que a tecnologia diminui os custos da comunicação global e das viagens. A globalização está a obrigar as empresas a serem mais competitivas ao mesmo tempo que os países reduzem as barreiras ao comércio internacional e ao investimento estrangeiro. A competitividade das empresas obriga-as a serem mais eficientes e eficazes, logo a pensarem os seus processos internos de forma a procurarem a sua otimização e melhorarem a sua produtividade, com a notória consequência na satisfação do cliente. Para a satisfação do cliente é necessário que as operações dentro do sistema de distribuição, nomeadamente as realizadas no armazém, sejam otimizadas. Esta otimização é atingida quando as encomendas dos clientes estiverem completas e prontas a serem despachadas em tempo útil e todos os processos necessários para o efeito tenham ocorrido no menor espaço de tempo possível e com o mínimo de recursos. O planeamento das operações no armazém tem de determinar o tempo e a ordem das operações bem como os recursos necessários de forma a não acontecerem congestionamentos. A Caetano Parts, uma empresa de revenda de peças de substituição automóvel, identificou um congestionamento na localização de peças que chegavam pela primeira vez ao seu armazém, o que suscitou a necessidade do desenvolvimento de uma ferramenta que permitisse proceder à localização destas peças de uma forma mais expedita, permitindo ganhos significativos de tempo na arrumação das peças e consequentemente no tempo gasto na sua procura/separação e posterior envio para os clientes. A ferramenta desenvolvida consiste num programa em Visual Basic for Applications (VBA) cuja conceção, desenvolvimento e descrição das funcionalidades serão abordados ao longo do trabalho. Os testes realizados ao longo do desenvolvimento validaram o correto funcionamento da ferramenta.

Characterization and application of two RANK-specific antibodies with different biological activities.

Antibodies play an important role in therapy and investigative biomedical research. The TNF-family member Receptor Activator of NF-κB (RANK) is known for its role in bone homeostasis and is increasingly recognized as a central player in immune regulation and epithelial cell activation. However, the study of RANK biology has been hampered by missing or insufficient characterization of high affinity tools that recognize RANK. Here, we present a careful description and comparison of two antibodies, RANK-02 obtained by phage display (Newa, 2014 [1]) and R12-31 generated by immunization (Kamijo, 2006 [2]). We found that both antibodies recognized mouse RANK with high affinity, while RANK-02 and R12-31 recognized human RANK with high and lower affinities, respectively. Using a cell apoptosis assay based on stimulation of a RANK:Fas fusion protein, and a cellular NF-κB signaling assay, we showed that R12-31 was agonist for both species. R12-31 interfered little or not at all with the binding of RANKL to RANK, in contrast to RANK-02 that efficiently prevented this interaction. Depending on the assay and species, RANK-02 was either a weak agonist or a partial antagonist of RANK. Both antibodies recognized human Langerhans cells, previously shown to express RANK, while dermal dendritic cells were poorly labeled. In vivo R12-31 agonist activity was demonstrated by its ability to induce the formation of intestinal villous microfold cells in mice. This characterization of two monoclonal antibodies should now allow better evaluation of their application as therapeutic reagents and investigative tools.

Kierkegaardian intersubjectivity and the question of ethics and responsibility

Kierkegaardian Intersubjectivity and the Question of Ethics and Responsibility By Kevin Krumrei. Kierkegaard's contributions to philosophy are generally admitted and recognized as valuable in the history of Western philosophy, both as one of the great anti-Hegelians, as the founder (arguably) of existentialism, and as a religious thinker. However valid this may be, there is similarly a generally admitted critique of Kierkegaard in the Western tradition, that Kierkegaard's philosophy of the development of the self leads the individual into an isolated encounter with God, to the abandonment of the social context. In other words, a Kierkegaardian theory of intersubjectivity is a contradiction in terms. This is voiced eloquently by Emmanuel Levinas, among others. However, Levinas' own intersubjective ethics bears a striking resemblance to Kierkegaard's, with respect to the description and formulation of the basic problem for ethics: the problem of aesthetic egoism. Further, both Kierkegaard and Levinas follow similar paths in responding to the problem, from Kierkegaard's reduplication in Works of Love, to Levinas' notion of substitution in Otherwise than Being. In this comparison, it becomes evident that Levinas' reading of Kierkegaard is mistaken, for Kierkegaard's intersubjective ethics postulates, in fact, the inseparability and necessity of the self s responsible relation to others in the self s relation to God, found in the command, "you shall love your neighbour as yourself."

Ethics in government and business

Canadians appear to hold the activities of those in government and in big business in low esteem. Media reports of several high-profile political and corporate instances of unethical conduct have reinforced the public's concern for the status of ethical conduct and honesty in government and in big business. The response by public and private sector managers to unethical conduct by employees is largely in the form of 'ethical rules' which both sectors agree provide a measure of certainty as to the ethical conduct expected from employees. Since research on ethics in the public and private sectors is limited and since ethics is a topic of increasing concern to both sectors, this thesis provides data that could assist managers in dealing with the issue of ethical conduct within their respective organizations. The purpose of this thesis is to compare the state of ethical conduct within public and private sector organizations in Canada. This is accomplished through a description and analysis of the approaches taken by the public and private sectors as well as the four professions of law, engineering, accountancy and medicine. Ethical conduct within the public sector focuses on the ethical behaviour of public servants rather than elected officials. The underlying intent of this thesis is to discover if contemporary ethical problems are similar in the public and iv private sectors with respect to the four ethical areas of conflict of interest, political activity, problem public comment and confidentiality. The comparative data on both public and private sector ethics are assessed and similarities and differences are identified. One major finding emerges from this study. Codes of ethics in both the public and private sectors are perceived by management to play an important role in the prevention of unethical conduct. A procedure for developing a code of ethics is presented along with recommendations as to the administration of a code of ethics. Finally, recommendations are made as to the role of education in ethics.

'What ever happened to breakdancing?' : transnational b-boy/b-girl networks, underground video magazines and imagined affinities

In 1997, Paul Gilroy was able to write: "I have been asking myself, whatever happened to breakdancing" (21), a form of vernacular dance associated with urban youth that emerged in the 1970s. However, in the last decade, breakdancing has experienced a massive renaissance in movies (You Got Served), commercials ("Gotta Have My Pops!") and documentaries (the acclaimed Freshest Kids). In this thesis, 1 explore the historical development of global b-boy/bgirl culture through a qualitative study involving dancers and their modes of communication. Widespread circulation of breakdancing images peaked in the mid-1980s, and subsequently b-boy/b-girl culture largely disappeared from the mediated landscape. The dance did not reemerge into the mainstream of North American popular culture until the late 1990s. 1 argue that the development of major transnational networks between b-boys and b-girls during the 1990s was a key factor in the return of 'b-boying/b-girling' (known formerly as breakdancing). Street dancers toured, traveled and competed internationally throughout this decade. They also began to create 'underground' video documentaries and travel video 'magazines.' These video artefacts circulated extensively around the globe through alternative distribution channels (including the backpacks of traveling dancers). 1 argue that underground video artefacts helped to produce 'imagined affinities' between dancers in various nations. Imagined affinities are identifications expressed by a cultural producer who shares an embodied activity with other practitioners through either mediated texts or travels through new places. These 'imagined affinities' helped to sustain b-boy/b-girl culture by generating visual/audio representations of popularity for the dance movement across geographical regions.

Locating Intergenerational Sense of Self: Intersections of Genealogy with Leisure and Tourism

Situated at the intersection of leisure and tourism, there is currently a renewed interest and curiosity in ancestral lineages. Focusing on amateur genealogists who pursue, and travel for, a leisure engagement of genealogy, this qualitative research study endeavours to investigate their quests for personal identity and locations of an intergenerational sense of self. With the adoption of a narrative inquiry method, life story interviews were conducted with four amateur genealogists. Findings from an analysis of the narratives have been organized into five core themes, each of which contributes to our understanding of these amateur genealogists’ experiences of leisure and travel. While the amateur genealogists do not acknowledge their leisure engagements as a quest for personal identity, they make use of such engagements to locate an intergenerational sense of self and gain enriched self-understandings. Moreover, by facilitating intersections of genealogy, leisure, and tourism, several key insights are offered that may be of particular interest to scholars in both fields of study.

The ‘Is’ of Fiction Elgin/Goodman Fictionalism : fictions in art and science

Cet essai a pour objet le rôle de la notion de fiction dans les domaines de l’art et de la science. Essentiellement, je soutiens que « fiction » dans ce contexte est « a category mistake » (concept versus genre) et je crois que cet essai peut réussir à « cuire du pain philosophique » en dévoilant une dispute verbale. Je suggère donc de clore un débat philosophique dans son intégralité. Je présente un exposé du style de fictionnalisme abordé par Catherine Z. Elgin et Nelson Goodman (que ce soit dans le contexte des arts ou des sciences, nous parvenons à la compréhension grâce à des fictions sous formes de « vérités non littérales ») et j’explore le concept de la fiction. Je soutiens que les représentations (textes descriptifs de toutes sortes, incluant les modèles) sont constituées d’éléments fictionnels et d’éléments facettés (à l’exception de la version idéale possible ou impossible, c’est-à-dire dans l’esprit de Dieu, qui n’inclurait que les facettes.) La compréhension ne peut provenir de la fiction, mais plutôt d’éléments facettés ordonnés de manière à créer une compréhension qui conduit généralement à des prédictions, des explications et des manipulations. Je définis les facettes comme ayant des caractéristiques organisées, alors que les fictions ont des caractéristiques désorganisées. La fiction dans son intégralité est donc, par définition, l’expression du néant (of nothing), ou en matière de langues idéales (mathématiques), l’expression de contradiction. Les fictions et les facettes relèvent des représentations qui sont elles-mêmes primitives. Les textes descriptifs sont donc fictionnels par degré. Les récits qui sont très fictionnels ont une certaine valeur (souvent ludique) mais contiennent toujours au moins une facette. En fin de compte, toutes les activités représentationnelles devraient être considérées irréelles, incomplètes, bien que parfois connectées à la réalité, c’est-à-dire, prises entre une description réaliste facettée et une fiction dans son intégralité.

Noticeability of corrective feedback, L2 development and learner beliefs

Cette étude quasi-expérimentale a pour but de 1) comparer la prise en compte et les effets de trois conditions rétroactives, à savoir la reformulation, l’incitation et un mélange des deux techniques, 2) déterminer le lien entre la prise en compte et l’apprentissage, et 3) identifier l’effet des perceptions des apprenants quant à la rétroaction corrective sur la prise en compte et l’apprentissage. Quatre groupes d’apprenants d’anglais langue seconde ainsi que leurs enseignants provenant d’un CEGEP francophone de l’île de Montréal ont participé à cette étude. Chaque enseignant a été assigné à une condition rétroactive expérimentale qui correspondait le plus à ses pratiques rétroactives habituelles. La chercheure a assuré l’intervention auprès du groupe contrôle. L’utilisation du passé et de la phrase interrogative était ciblée durant l’intervention expérimentale. Des protocoles de pensée à haute voie ainsi qu’un questionnaire ont été utilisés pour mesurer la prise en compte de la rétroaction corrective. Des tâches de description d’images et d’identification des différences entre les images ont été administrées avant l’intervention (pré-test), immédiatement après l’intervention (post-test immédiat) et 8 semaines plus tard (post-test différé) afin d’évaluer les effets des différentes conditions rétroactives sur l’apprentissage des formes cibles. Un questionnaire a été administré pour identifier les perceptions des apprenants quant à la rétroaction corrective. En termes de prise en compte, les résultats indiquent que les participants sont en mesure de remarquer la rétroaction dépendamment de la forme cible (les erreurs dans l’utilisation du passé sont détectées plus que les erreurs d’utilisation de la phrase interrogative) et de la technique rétroactive utilisée (l’incitation et le mélange d’incitation et de reformulations sont plus détectés plus que la reformulation). En ce qui a trait à l’apprentissage, l’utilisation du passé en général est marquée par plus de développement que celle de la phrase interrogative, mais il n'y avait aucune différence entre les groupes. Le lien direct entre la prise en compte et l’apprentissage ne pouvait pas être explicitement établi. Pendant que la statistique inférentielle a suggéré une relation minimale entre la prise en compte du passé et son apprentissage, mais aucune relation entre la prise en compte de la phrase interrogative et son apprentissage, les analyses qualitatives ont montrés à une association entre la prise en compte et l’apprentissage (sur les deux cibles) pour certains étudiants et augmentations sans prise en compte pour d'autres. Finalement, l’analyse factorielle du questionnaire indique la présence de quatre facteurs principaux, à savoir l’importance de la rétroaction corrective, la reformulation, l’incitation et les effets affectifs de la rétroaction. Deux de ces facteurs ont un effet modérateur sur la prise en compte de la rétroaction sans, toutefois, avoir d’impact sur l’apprentissage.

La représentation de la machine dans la trilogie d’anticipation scientifique d’Albert Robida : du texte à l’image et de l’image au texte

Cette thèse étudie la représentation de la machine chez Robida. La partie centrale de notre recherche s’intéresse à révéler ses significations et interroge sa mise en scène littéraire et visuelle dans chacun des romans de la trilogie d’anticipation scientifique la plus connue de l’auteur-illustrateur. La quête se transforme en un voyage continu entre le lisible et le visible, le dit et le non-dit, la description littéraire et l’imagination, la réalité et la fiction. Nous nous intéressons à l’évolution de la vision de Robida : dans Le Vingtième siècle, l’image de la machine bienfaisante, facilitant la vie de l’homme, économisant du temps et de l’argent, et contribuant largement à son bonheur et à son divertissement, à part quelques accidents très limités, se traduit par une complémentarité avantageuse entre le texte d’une part et les vignettes, les tableaux et les hors-textes se trouvant dans le récit, d’autre part. Celle-ci se transforme, dans La Guerre au vingtième siècle, en une inquiétude vis-à-vis de l’instrumentalisation de la machine pour la guerre, qui s’exprime par une projection de la narration vers l’illustration in-texte, et sensibilise le lecteur en montrant le caractère violent et offensif d’appareils uniquement nommés. Celle-ci devient finalement, dans La Vie électrique, synonyme d’un pessimisme total quant à l’implication de la machine dans la société et à la puissance du savoir scientifique dans l’avenir, qui s’affiche dans des hors-textes sombres et maussades. Dans ce cadre, la machine illustrée exige une lecture iconotextuelle, une importance accordée au détail, aux éléments présents ou absents, aux modalités de passage d’un mode de présentation à l’autre, à la place anticipée ou tardive de l’illustration, au rapport entre le texte, le dessin et sa légende, aux mots qui migrent vers le dessin et surtout au reste du décor incomplet. Chez Robida, les louanges qui passent à la critique et l’humour qui se fait cynisme, sont assez représentatifs des espoirs et des craintes suscités par la découverte et la mise en application de l’électricité, par ses vertus, mais aussi par son aspect incontrôlable.

INDIAN AND ANTARCTIC BRYOZOANS - TAXONOMY AND OBSERVATIONS ON TOXICOLOGY

This thesis embodies findings on a taxonomical investigation of a group of lower marine invertebrates belonging to the category coelomata. Bryozoans are well known both in fossil and recent taxonomical history. They comprise of about 5,000 living and 16000 fossil species. Bryozoans are well known for their taxonomic abundance and structural diversity,representing the various ecological niches ranging from the intertidal to the abyssal benthic. At a time when global marine biological diversity has become a concern of not only to the scientists but also to the policy makers,an understanding of species diversity and abundance are cardinal aspects of biological studies. Geological time scales which is known that by Pre-Cambrian, marine invertebrate diversity reach the maximum and this diversity has become more comprehensive as time advanced. Taxonomists a vanishing species of scientists have become more concerned in discerning patterns of species diversity. The basic tool for this is identification fo animals. with this idea in mind a detailed study of taxonomy of bryozoan was undertaken . The major part of this thesis is devoted to describe various species of bryozoans with detailed description and ecotypical variations.The pattern of distribution and abundance which are important aspects of animal groups have also been documented. Possible effects of heavy metal contamination on the tolerance and growth of bryozoans, a few species of which have been eliminated from the chronically polluted areas of Cochin backwaters have also been documented.

Studies on Some Aspects of Landings,Utilization and Export of Commercially Important Cephalopods

In the present study two aspects of cephalopod fishery such as (i) landings and (ii) utilization including export of cephalopods from Indian are dealt with. Under the topic landings, craft, both traditional and mechanized and fishing techniques employed for capturing cephalopods are discussed. General trend in cephalopod landing in India and particularly south west coast, species composition, description and geographic distribution of important species of cuttle fishes, squids and octopus and the distribution and abundance of cephalopods along the continental shelf of the south west coast are also discussed. Some biological aspects like population parameters, maturation and spawning, food and feeding of the two representive species of cuttle fishes and squid viz, Sepia pharaonis and Loligo duvauceli are studied.Under utilization, general handling and processing of various frozen cephalopods products for exports and commercial operation in a typical plant are studied. The export of cephalopod products since its commencement is studied in detail and market strategy for enhancing the export are suggested.

Numerical Modelling of Tsunami Propagation in the South East Arabian Sea (SEAS) and Inundation along the Kerala Coast

Tsunamis are water waves generated by a sudden vertical displacement of the water surface. They are waves generated in the ocean by the disturbance associated with seismic activity, under sea volcanic eruptions, submarine landslides, nuclear explosion or meteorite impacts with the ocean. These waves are generated in the ocean and travel into coastal bays, gulfs, estuaries and rivers. These waves travel as gravity waves with a velocity dependent on water depth. The term tsunami is Japanese and means harbour (tsu) and wave (nami). It has been named so because such waves often develop resonant phenomena in harbours after offshore earthquakes.

Tourist Profiles and Characteristics vis-à-vis Market Segmentation of Ecotourism Destinations in Kerala

Kerala, a classic ecotourism destination in India, provides significant opportunities for livelihood options to the people who depend on the resources from the forest and those who live in difficult terrains. This article analyses the socio-demographic, psychographic and travel behavior patterns and its sub-characteristics in the background of foreign and domestic tourists. The data source for the article has been obtained from a primary survey of 350 randomly chosen tourists, 175 each from domestic and foreign tourists, visiting Kerala’s ecotourists destinations during August-December 2010-11. Several socio-demographic, psychographic and life style factors have been identified based on the inference from field survey. There is considerable divergence in most of the factors identified in the case of domestic and international tourists. Post-trip attributes like satisfaction and intentions to return show that the ecotourism destinations in Kerala have significant potential that can help communities in the region.
