The aim of our study is to analyze the effects of this increase in the use that the customer has of your card, with the assumption that the client will use more, or by anchoring, since he cares to always have a spare limit for any emergencies, or feel prioritized by the bank, or even by pentup demand for credit. For this, we analyzed a database, with test and control groups of selected customers to limit increase, and noted that the increase has caused customers to increase their spending, their balances, have become more transactions and timidly began to revolve. After observing these effects, we divided the group into two: Customers with average use less than or equal to 50% before the action and customers with average utilization greater than 50% before the action. The test group of the customers of both groups showed an increase in monthly spending, the number of monthly transactions, the outstanding balance and the number of revolver customers. This difference was greater in the group with higher average utilization in the moment of the action, but even customers who initially seemed to have a lower credit demand, showed sensitivity to use more because of the increased limit. / No Brasil os emissores de cartão de crédito realizam periodicamente aumento de limites do cartão, para clientes que possuem bom comportamento creditício. O objetivo do nosso estudo é analisar os efeitos desse aumento no uso que o cliente tem do seu cartão, com a hipótese de que o cliente passará a utilizar mais o cartão, seja por anchoring, visto que ele se importa em sempre ter uma reserva de limite para eventuais emergências, ou por se sentir priorizado pelo banco, ou até mesmo por demanda reprimida de crédito. Para isso, analisamos uma base de aumento de limite, com grupo de teste e controle, de clientes selecionados para aumento de limite, e observamos que o aumento fez com que os clientes aumentassem seus gastos, seu saldo devedor, passaram a fazer mais transações e timidamente passaram a rotativar. Após observar esses efeitos, dividimos o grupo em dois: Clientes com utilização média menor ou igual a 50% antes da ação e clientes com utilização média maior que 50% antes da ação. Para os clientes do teste dos dois grupos observamos um aumento no gasto mensal, no número de transações mensal, no saldo devedor e no número de clientes rotativando. Essa diferença foi maior no grupo de maior utilização pré tratamento, mas mesmo clientes que inicialmente pareciam ter uma demanda de crédito menor, mostraram-se sensíveis a utilizar mais devido ao aumento do limite.

The survey form try to capture the Vroom s Expectance Theory constructs of Valence, Instrumentality, Expectation and Motivational Force, and also the Tversky and Kahneman Anchoring effect in terms of grade expected. The main findings suggest that the minimum grade required by the school is much strong in driving the students motivation and performance than the Expectancy Theory.

L'ancrage territorial par une géographie multilocale : le cas des entreprises de la filière des plantes à parfum, aromatiques et médicinales dans la vallée de la Drôme / the territorial anchoring for a geography multi-local

Duffaud, Marie-Laure 25 February 2015 (has links)
La notion d’ancrage est au cœur de cette thèse. Nous l’abordons dans sa dimension temporelle et spatiale. Nous partons de l’hypothèse que l’ancrage d’une activité est un construit permanent qui mobilise des ressources variables dans le temps pour répondre à un marché labile. D’un point de vue spatial, l’ancrage dépendrait de la capacité des acteurs à être mobiles. Nous travaillons cette hypothèse à partir du cas des entreprises de la filière des plantes à parfum, aromatiques et médicinales installées dans la vallée de la Drôme. Cette petite filière est riche de son originalité : multiplicité des avals, fonctionnement mondialisé faiblement soutenu par les institutions, politique de gamme, produits de qualité générique ou spécifique, pilotage par l’aval. Notre cadre théorique est celui de l’approche territoriale mobilisant les concepts d’acteurs et de ressources. Au-delà de la volonté d’ancrage personnel des entrepreneurs, les résultats soulignent d’abord une construction de l’ancrage dans une dynamique collective. Mais celle-ci a du mal à se structurer en raison de la compétition entre les entreprises. Avec le temps, les partages deviennent plus informels. Toutefois, l’agglomération de ces entreprises, l’offre variée qu’elles proposent autour des différents avals, contribuent à forger une réputation collective au sein de la filière. L’ancrage tient donc à ce construit collectif mais également à une capacité à renouveler des ressources en réponse au marché, qui réclame des gammes allant du produit générique au produit très spécifique, avec une part d’intrants symboliques de plus en plus forte. À cette fin, les entrepreneurs construisent des stratégies multilocales pour répondre au marché et assurer la pérennisation de l’entreprise. Au centre de l’agencement spatial émerge un territoire dans ses multiples dimensions, dont chacune fait ressource : réseau localisé d’entreprises, territoire identitaire (hérité et construit) auquel vient aujourd'hui se superposer un territoire de projet institutionnel, le projet Biovallée®. Au-delà de ce lieu d’ancrage, non balisé, s’organise une forme en réseau qui court-circuite l’emboitement traditionnel des échelles. Les ressources de cet Ailleurs sont multiples et sont sollicitées de façon flexible : marché, connaissances, financement et surtout production. Ainsi, l’ancrage s’inscrit dans un agencement spatial fluctuant qui permet l’adaptation à un marché de plus en plus labile. / This research is about the territorial anchoring of economic activities in less favored rural areas. We approach it in its temporal and spatial dimension. We start from the assumption that anchoring is a permanent movement which mobilizes variable resources meeting the needs of a labile market. From a spatial perspective, anchoring could depend on the ability of actors to be mobile. We have tested this hypothesis using the case study of companies working in the sector of perfume, aromatic and medicinal plants and geographically located in a rural area in Drôme valley. This small industry is indeed very original/off beat - multiple downstream markets, a range of products of generic or specific quality, buyers driven dynamic. This industry is very global and not protected by the common market organizations. The territorial approach is our theoretical framework mobilizing the concepts of actors and resources. Beyond the anchoring will of entrepreneurs, our results underline fist the impact of a collective dynamic on anchoring. But this collective resource is difficult to structure due partly to a competition between companies. Indeed, the dynamic tends to evolve towards a coopetition in which the shares are becoming more and more informal. However, agglomeration of these companies and the varied selection they offer around different targets contribute to the building of a collective reputation within the sector. The collective action is thus an important part of anchoring as much as the ability to renew resources to meet the demands of market calling for product lines going from generic product to very specific product with more symbolic input. In this context, entrepreneurs have multi-local strategies to meet demands and ensure the success of their business. In the heart of this spatial arrangement a territory in its many dimensions emerges -localized network of companies, identity place (inherited and built) and today an institutional project, on which the Biovallée project® is superimposed. Beyond this place of anchorage with fluid boundaries lies a network relation which shortcuts the traditional fitting of scales. The resources of this “elsewhere” are multiple and support the local system bringing market, knowledge, funding and raw material. Thus, the anchoring of these activities fits in a fluctuating spatial arrangement that enables adaptation to a labile context.

Les rêves et leur interprétation : systèmes interprétatifs culturels et interprétation psychanalytique / Dreams and their interpretation : cultural interpretative systems and psychoanalytical interpretation

Bauer-Motti, Fanny 13 March 2015 (has links)
Cette thèse porte sur le processus interprétatif associé au rêve et son ancrage culturel. Si l’interprétation des rêves est une des grandes voies d’accès à l’Inconscient, elle est également un trait propre à certaines cultures. Si les processus psychiques inconscients en eux-mêmes sont universels en tant qu’ils sont propres à tout sujet, propres à la dimension humaine, l’ancrage culturel du « rêveur » est, quant à lui, circonstanciel. L’exploration s’est faite à l’Ile Maurice à partir d’entretiens réalisés dans les différentes communautés religieuses de l’Ile. Cette recherche aborde « l’inscription culturelle du rêve » dans différentes théories et sur le terrain de recherche, « le rêve et son interprétation » dans une perspective psychanalytique et ethnologique pour délimiter la notion de « préalable interprétatif », les questions méthodologiques spécifiques à ce travail et elle procède au traitement et à l’analyse de 9 entretiens. Le processus du rêve, de son élaboration à son interprétation, se constitue à partir d’un préalable interprétatif dont le rêve est porteur lorsque pour le rêveur il existe un système d’interprétation possible du rêve, que celui-ci soit psychanalytique ou culturel. Ce préalable culturel et forcément partagé fait partie des éléments du rêve, tout aussi présents que les éléments diurnes, les souvenirs etc. dont parle Freud. Cette thèse ouvre sur la prise en compte du socle culturel dans un travail de psychologue clinicienne dans une culture autre que la sienne. / This thesis focuses on the interpretive process associated with the dream and its cultural roots. If the interpretation of dreams is one of the major access routes to the unconscious, it is also a specific characteristic to some cultures. If the unconscious psychic processes are universal because they are specific to a person, specific to the human dimension, the cultural anchoring of the “dreamer” is circumstantial. The exploration has been done in Mauritius from interviews in the different religious communities of the island. This research addresses the "cultural inscription of dreams” in different theories and the field search; "the dream and its interpretations" in psychoanalytic and ethnological perspective to establish a framework for the concept of "pre- interpretive"; the methodological issues regarding this research and the treatment and analysis of 9 interviews. The process of the dream, from its development to its interpretation, is formed from a pre-interpretive which is in the dream when for the dreamer there is a possible dream interpretation system, whether it is psychoanalytic or cultural. This cultural prior and necessarily shared is a part of the dream elements, as well as the diurnal items, souvenirs etc. mentioned by Freud. This thesis opens to the consideration of a cultural basis within the work of a clinical psychologist in another culture.

Vaňkátová, Eva January 2017 (has links)
This thesis is focused on research of school undiscipline (misbehaviour) by using the anchoring vignettes method. The results obtained of qualitative research (focus groups and in-depth interviews) were used for the compilation of the vignettes and questionnaire. In its theoretical part, the thesis introduces with multi-dimensional concept of school discipline and with works of the other authors. Further the thesis presents an overview of research methods for measuring of school discipline. The practicle parts presents the results of the author's own survey. These results have led for construction of the questionnaire with anchoring vignettes. These ones were compiled by using results of focus groups with 13 - 15 years old pupils and in-depth interviews with their teachers. The final questionnaire will be standardized within author's doctoral studies a thesis. Even so, it appeals that the anchoring vignette method takes its place in educationas scienses.

Bedömning av ålder via stillbild och rörlig bild / Assessment of age through still and moving picture

Nyborg, Claes January 2010 (has links)
Studier inom åldersbedömning har ofta gjorts med stillbilder av ansikten. Denna studiesyftade till att undersöka om åldersskattningar mellan helkroppsbilder av stillbilder ochrörliga bilder skiljer sig åt. Vidare undersöktes om män bedöms med bättre precision änkvinnor, om precisionen är bättre då bedömaren är av samma kön som den som blir bedömdsamt om åldern underskattas på personer över 40 år och överskattas på personer under 40 år.Datainsamlingen skedde via en webbaserad plattform för enkätundersökningar som för engrupp visade stillbilder och för en annan grupp visade rörliga bilder. Resultatet visade intenågra skillnader i precisionen för bedömning mellan stillbilder och rörliga bilder eller dåbedömningen gjordes inom samma kön (kvinna-kvinna och man-man). Däremot visade detsig att män bedöms med högre precision än kvinnor och att åldern på personer över 40 årunderskattas och att åldern på personer under 40 år överskattas. / Studies within age estimation have often used still pictures of faces. The purpose of this studywas to investigate if there is a difference in the precision of age estimation between still andmoving pictures of full bodies. It was also investigated if the precision is higher whenestimating males rather than females, if the precision is higher when the estimation is done bya individual with same sex as the one getting estimated, if the age of people over the age offorty is underestimated and if the age of people under the age of forty is overestimated. Thecollection of data was done through a web based platform for surveys, from which one groupwas showed still full body pictures and the other group was showed moving full bodypictures. The results showed no difference in estimation precision between still pictures andmoving pictures or when the estimation was done within the same gender (female-female andmale-male). However the results showed that males are estimated with higher precision thanfemales as well as that the age of people over the age of forty is underestimated and the age ofpeople under the age of forty is overestimated.

Construção de sistema que permite a ancoragem de proteína recombinante à superfície celular de levedura. / Construction of a system that allows anchoring of recombinant protein to the cell surface of yeast.

Jessica Paola Fuentes Rivera Navarro 03 July 2008 (has links)
Sistemas do tipo cell surface display vêm sendo desenvolvidos para expressão de proteínas heterólogas ancoradas à superfície celular de microrganismos. Várias aplicações foram reportadas destes sistemas, incluindo o emprego como biocatalizador celular, desenvolvimento de vacinas e biosorventes celulares. Neste trabalho foi desenvolvido um sistema que permite ancoragem da proteína glicoamilase de Aspergillus awamori à superfície da parede celular da levedura Saccharomyces cerevisiae. O gene codificador da glicoamilase com sua seqüência sinal foi fusionado ao fragmento do gene codificador da região C-terminal da proteína Flo1p (Flo428), que foi utilizada como âncora (fragmento CG*FC). As células de levedura foram transformadas com o fragmento híbrido CG*FC e os transformantes foram capazes de degradar amido e liberar glicose. A atividade da glicoamilase não foi detectada no meio de cultura, porém está presente no sedimento celular. Estes resultados demonstram que a glicoamilase foi ancorada à parede celular da nova linhagem recombinante de levedura. / Cell surface display systems have being developed for expression of heterologous proteins anchored to the cell surface of microorganisms. Several applications of these systems have been reported, including employment as whole-cell biocatalysts, development of vaccines and cellular biosorvents. In this work it was developed a system that allows the anchoring of the Aspergillus awamori glucoamylase protein to the cell wall surface of the yeast Saccharomyces cerevisiae. The gene encoding glucoamylase with its secretion signal was fused to the gene fragment encoding the C-terminal region of Flo1 protein, used as an anchor (CG*FC fragment). Yeast cells were transformed with hybrid CG*FC fragment and transformants were able to degrade starch and release glucose. Glucoamylase activity was not detected in the culture medium, but only in sedimented cells. These results demonstrate that glucoamylase was anchored to the cell wall of the new yeast recombinant strain.

A toughened composite for improving the anchoring of composite tensile armors of flexible risers / Un composite renforcé pour améliorer l’ancrage des armures de traction en composite des risers flexibles / Compósito para melhoria da ancoragem das armaduras de tração de compósito de risers flexíveis

Pereira Mattedi, Rafael 02 July 2019 (has links)
L'utilisation de composites et nano composites est une tendance croissante dans des industries telles que l'aérospatiale, l'automobile et l'énergie. Pour de nombreuses applications, l'adhésion entre des structures pour bien transférer les efforts est un problème difficile à résoudre. Dans l’industrie pétrolière, par exemple, une technique utilisée pour ancrer les armures de traction d’une conduite flexible est à travers un époxy intégré car elle fournit une bonne résistance mécanique et chimique. Cependant, des fissures et des défauts peuvent apparaître dans le bloc époxy pendant les opérations ou le montage lors de l'étape de cuisson de l'époxy, et ces fissures pourraient affecter les performances d'ancrage, en particulier pour les armures composites en fibre de carbone (CFAs). Dans ce contexte, ce travail propose le renforcement de l'époxy pour l'ancrage du CFA, focalisé sur les propriétés mécaniques et d'adhérence. Un modèle analytique est développé pour le mécanisme d'ancrage du CFA et vérifié par analyse numérique pour évaluer la sensibilité du système aux caractéristiques de l’époxy. Ainsi, l'augmentation de ces propriétés est proposée par l'ajout de nanotubes de carbone multi-feuilles (MWCNTs) et des essaies sont réalisées avec le époxy pur et renforcés pour caractériser l’augmentation des propriétés mécaniques et adhésives. Ensuite, la morphologie des nanotubes et l'homogénéité de la matrice sont investiguées pour corréler avec des résultats mécaniques. La recherche a confirmé une amélioration de la résistance à l'ancrage en renforçant la matrice époxy avec des MWCNTs. / The use of composite and nanocomposites is a growing trend in many industries such as aerospace, automotive and energy. For many applications, the adhesion between structures for efficiently transferring loads is a difficult problem to solve. In oil and gas segment, for instance, a common technique used for anchoring the tensile armors of flexible riser within the end fitting is through an embedded epoxy since it provides good mechanical and chemical resistance. Even though, cracks and defects can arise in the epoxy block during operations or mounting at epoxy curing step, and such cracks could affect the anchoring performance, in particular for carbon fiber composite armors (CFA). In this context, this work proposes the improvement of the epoxy for anchoring the CFA, with a focus on the mechanical and adhesion properties. An analytical model is developed for CFA anchoring mechanism and verified by numerical analysis to evaluate the sensitivity of the system to the epoxy characteristics. Thus, the increase of these properties is proposed by adding multi-walled Carbon Nanotubes (MWCNTs) and some experiments are carried out with neat and toughened epoxies to characterize the gain of mechanical and adhesive properties. Then, nanotubes morphology and the matrix homogeneity are expertized to correlate with mechanical results. The research confirmed an improvement of anchoring resistance by toughening the epoxy matrix with MWCNTs. / O uso de compósitos e nano compósitos é uma tendência crescente em muitas indústrias, como aeroespacial, automotivo e energia. Para muitas aplicações, a adesão entre estruturas para transferência eficiente dos esforços é um problema de difícil solução. No segmento de óleo e gás, por exemplo, uma técnica comum utilizada para ancorar as armaduras de tração do tubo flexível dentro do conector é através de um epóxi embebido, pois proporciona boa resistência mecânica e química. No entanto, trincas e defeitos podem surgir no bloco de epóxi durante as operações ou montagem, na etapa de cura do epóxi, e tais defeitos podem afetar a performance de ancoragem, em particular para armaduras de compósito de fibra de carbono (CFA). Neste contexto, este trabalho propõe a melhoria do epóxi para ancorar o CFA, com foco nas propriedades mecânicas e adesivas. Um modelo analítico é desenvolvido para o mecanismo de ancoragem do CFA e verificado por análise numérica para avaliar a sensibilidade do sistema às características do epóxi. Assim, o aumento dessas propriedades é proposto pela adição de nano-tubos de carbono de múltiplas paredes (MWCNTs) e alguns experimentos são realizados com os epóxis puro e modificado para caracterizar o ganho de propriedades mecânicas e adesivas. Em seguida, a morfologia dos nano-tubos e a homogeneidade da matriz são investigadas para correlacionar com os resultados mecânicos. A pesquisa confirmou uma melhoria da resistência à ancoragem ao tenacificar a matriz de epóxi com MWCNTs.
