Voyage au coeur de la prédation entre vendeurs et acheteurs : une nouvelle théorie en vente et marketing

Mesly, Olivier January 2010 (has links)
Résumé : II existe une tension inhérente au sein de la relation en cours de développement entre un vendeur et un acheteur. Le vendeur craint que l'acheteur lui fasse perdre son temps et l'acheteur, lui, doute de l'honnêteté du vendeur. Tous deux s'interrogent sur le niveau de confiance et de coopération à accorder à l'autre. Il est possible, après tout, que le vendeur soit à l'affût de la moindre faiblesse de l'acheteur pour profiter de la situation et s'enrichir à ses dépens, ou, vice-versa, que l'acheteur cherche à profiter du vendeur. La présente thèse examine les tensions entre vendeurs et acheteurs en ayant recours à la théorie enracinée élargie, qui comprend une série de boucles investigatrices formées de revues des écrits scientifiques et de cueillettes de données qualitatives et quantitatives. Elle cherche à démontrer que la prédation perçue (l'impression que l'autre abuse de nous de manière coordonnée) affecte négativement la bonne entente entre les parties prenantes de la transaction. La thèse suggère aussi que le phénomène de prédation existe dans toutes les sphères d'activités humaines, y compris dans le domaine juridique. Le modèle PARDU (prédateur-proie) initialement développé pour discuter du phénomène de prédation débouche, au fil de la recherche, sur le modèle OPERA et la grille MESLY®, qui offrent des applications pratiques pour mieux gérer la prédation informationnelle.||Abstract : There is an inherent tension between a seller and a buyer as their relationship progresses towards closing the deal. The salesperson fears that the buyer wastes his time, which he could otherwise spend towards real potential buyers. The buyer questions the sincerity of the salesperson. Both evaluate the amount of trust and coopération they should invest in the relationship. It is possible, after ail, that the salesperson wants to take advantage of every weakness he detects in the buyer in order to guarantee the sale, and it is equally possible that the buyer tries to fool the salesperson, with false credit information for example. This thesis examines tensions that exist between salespeople and buyers by using an extended version of grounded theory, by which date is collected and analysed both qualitatively and quantitatively. It demonstrates that perceived prédation reduces considerably the quality of the relationship. The thesis suggests that the phenomenon of prédation exists in every sphere of human activity, including in the légal system. The PARDU Model (predator-prey) initially developed to discuss the phenomenon of predation evolves, as the research progresses, towards the OPERA Model and the MESLY® grid, which offer pratical tools to better manage informational predation.

Outcome predictors of co-operative R&D in Europe : organisational capabilities and cultures

Zibell, Laurent January 2010 (has links)
This research investigates organisational capabilities and cultures of both partners as potential explanatory factors of co-operative R&D projects outcomes. Contributions to theory are (1) a justification for the existence of organisational capabilities and 'world views', (2) a parsimonious typology of 'world views' and (3) a method to measure organisational capabilities. The survey covers 514 projects in the electronics industry, in Germany, France, the United Kingdom and Finland. It obtains 120 full answers, each of which coupling responses from a matched pair of project managers having co-operated on the same R&D project. The survey refers to the organisation's capabilities, to those of the partner, to its 'world view', and to project outcomes. None of the traditional explanatory factors (geographic distance, difference in nationality, size or legal status, strategic compatibility) has any significant influence on any of the outcomes being studied (save one). The explanatory factors introduced by the research (organisational capabilities and 'world views') have a significant influence on almost all outcomes being considered of the co-operative R&D projects: attainment of concrete results, compliance with budget and schedule, creation and transfer of knowledge, learning (modification of capabilities). Cultural diversity, 'absorptive capacity', and teaching effects, selective according to the capability in question, are evidenced. Commonalities between partners are shown to be more important than distance. These results validate empirically organisational capabilities and 'world views' as descriptors of inter-organisational capabilities, and their operationalisation.

Efeitos sinérgicos em complexos binucleares de rutênio com um ligante benzobisimidazol em ponte para oxidação da água / Synergistic effect in ruthenium complexes bridged by a benzobisimidazole ligand, precursors of water oxidation catalysts

Benavides, Paola Andrea 14 August 2017 (has links)
Este trabalho está focado no desenvolvimento de complexos de rutênio binucleares baseados no ligante ponte 2,6-bis(2-piridil)benzodiimidazol (dpimH2) com potencial aplicação como catalisadores para oxidação da água. O acoplamento eletrônico entre os centros metálicos bem como as propriedades eletrônicas e catalíticas podem ser controlados via reações ácido-base no ligante bis-bidentado. Dessa forma, neste trabalho descrevemos o preparo e a caracterização do respectivo composto mononuclear, bem como do complexo binuclear simétrico [{RuCl(phtpy)}2(dpimH2)](Otf) 2 (onde phtpy=4-fenil-2,2\':6\',\'\'-terpiridina), e do análogo assimétrico [{Ru(bpy)2}(dpimH2){Ru(phtpy)Cl}](ClO4)3 (onde bpy=2,2\'-bypiridina), que possui um centro catalítico e um grupo cromóforo na mesma molécula como esperado em um fotocatalisador, em que os dois centros catalíticos estão covalentemente conectados através do ligante ponte funcional. As caracterizações estrutural e eletrônica de ambos os complexos por 1H RMN, ESI-MS e espectroscopia de absorção UV-Vis indicaram a presença de isômeros geométricos com perfis eletrônicos similares. Por outro lado, a análise eletroquímica por voltametria cíclica demonstrou menores potenciais Ru(III/II) quando comparados a complexos polipiridínicos análogos. Este potencial redox pode ainda ser catodicamente deslocado através da remoção de prótons dos grupos imidazóis do ligante ponte, possibilitando, dessa forma, a modulação das propriedades eletrônicas e catalíticas destes complexos de rutênio através de reações de protonação/desprotonação dos grupos -NH. Além disso, neste trabalho é investigada a inesperada formação do complexo [Ru(phtpy)2] nas reações do complexo [RuCl3(phtpy)] puro com ligantes bidentados, utilizando-se espectroscopia UV-Vis e de 1H RMN. / This work is focused on the development of dinuclear ruthenium complexes with potential application as catalysts for oxidation of water, that are characterized by a benzobisimidazole 2,6-bis(2-pyridyl)benzodiimidazole (dpimH2) bridging ligand, whose interaction between the metal centers as well as the electronic and catalytic properties can be tuned by acid-base reactions in that moiety. Thus, the preparation and characterization of the respective mononuclear species are described. The dinuclear complex [2(dpimH2)](Otf)2(phtpy=4-phenyl-2,2\':6\',2\'\'-terpiridine), in which two catalytic centers are covalently linked through that bridging ligand, and of the [(dpimH2)](ClO4)3 complex (where bpy=2,2\'-bypiridine) integrating a chromophore and a catalytic center in the same molecule as expected for a photocatalyst. The structural and electronic characterization of both complexes by NMR, ESI-MS and UV-vis spectroscopy indicated the presence of geometric isomers with similar electronic profiles. On the other hand, the electrochemical analysis by cyclic voltammetry displayed redox potential values for the Ru3+/Ru2+ couples lower than the respective polypyridyl complex counterparts. This redox potential can be even more shifted to less positive potentials by removal of protons from the imidazole groups in the bridging ligand, opening the possibility of tuning the electronic and catalytic properties of those ruthenium complexes based on protonation/deprotonation of the -NH groups. Furthermore, in this work is analyzed the unexpected formation of the bisterpyridine [Ru(phpy)2] complex in reactions starting with pure [RuCl3(phtpy)] complex with bidentated ligands, as through UV-Vis spectroscopy and RMN.

Les objets mathématiques dans la théorie platonicienne de la connaissance et de l'action / The mathematical objects in the platonic theory of the knowledge and the action

Rivière, Xavier 18 November 2016 (has links)
La connaissance implique une prédisposition à la connaissance, c’est-à-dire la possibilité de la relation entre un sujet (connaissant) et un objet (connaissable). D’un autre côté, il y a un état de fait, qui est la connaissance qui a lieu, de fait : la connaissance courante, ordinaire, toujours incomplète, à laquelle l’homme se trouve incessamment avoir accès ou être en train d’avoir accès. La connaissance véritable – pleine et entière – se trouve située à l’extérieur de ce domaine cognitif ordinaire ; extériorité qui implique une indisposition présente à y avoir accès. La connaissance mathématique est du premier ordre – et ce, éminemment, autrement dit, à la fois, en tant que meilleure connaissance possible et en tant que connaissance révélant, le mieux, au travers de son propre inachèvement, l’inachèvement de toute connaissance accessible (dont elle est constitutive ou auxiliaire). Du second ordre, est la connaissance eidétique (connaissance des Formes – eidê, ideai – autrement appelées Idées), qui est la connaissance du réellement réel (ontôs on) (dont l’objet, en sa saisie, ne peut que signer la réelle réalité de la connaissance elle-même). De son côté, la connaissance mathématique induit, en son inachèvement, la connaissance de son principe et élément, qu’est l’unité véritable (c’est-à-dire unique, indivisible et indifférenciée, et donc paradoxalement inconnaissable, en quoi, elle induit, elle-même, l’ordre de la connaissance véritable, qu’est l’ordre eidétique), unité censée trouver, dans l’ordre géométrique, son expression, en tant que mesure et élément communs à tout le mesurable (l’étendu) et, du même coup, à tout le dénombrable ; expression géométrique qui ne manque pas d’être problématique (aporétique), la grandeur demeurant, dans l’absolu, indéfinie, et toute grandeur étant divisible à l’infini, en grandeurs plus petites. Ainsi, se trouve attesté le fait que la disposition cognitive présente (ordinaire) est inéluctablement en deçà d’être disposition à la connaissance véritable, en ce que celle-ci devrait être notamment connaissance du principe, principe que nous pensons trouver désigné, chez Platon, sous l’expression « principe de la ligne », principe dynamique et actif, proprement non mathématique, toujours antérieur à quelque détermination (grandeur) – et, du même coup, à quelque dénombrement – que ce soit. / The knowledge implies a predisposition to the knowledge, that is the possibility of the relation between a (knowing) subject and a (knowable) object. On the other hand, there is an established fact, which is the knowledge which has de facto place : the common, ordinary, always incomplete knowledge, to which the man is continuously to have access or to be having access. The real knowledge – full and whole – is situated outside of this ordinary cognitive domain ; exteriority which implies a present indisposition to have access there. The mathematical knowledge is of the first order – and it is true eminently, in other words, at the same time, as better possible knowledge and as knowledge revealing, best, through its own incompletion, the incompletion of any accessible knowledge (whose it is constitutive or auxiliary). Of the second order, is the eidetic knowledge (knowledge of the Forms – eidê, ideai – otherwise called Ideas), which is the knowledge of the really real (ontôs on) (whose the object, in its grasp, can only sign the real reality of the knowledge itself). From her part, the mathematical knowledge leads, in its incompletion, the knowledge of its principle and element, that is the real unit (that is unique, inseparable and undifferentiated, and thus paradoxically unknowable, in what, it leads, itself, the order of the real knowledge, that is the eidetic order), unit supposed to find, in the geometrical order, its expression, as measure and element common to all the measurable (the extent) and, at the same time, to all the countable ; expression which does not miss to be problematic (aporetic), the size remaining, theoretically, indefinite, and any size being divisible in the infinity, in smaller sizes. So, is attested the fact that the present (ordinary) cognitive disposition is inevitably to be disposition to the real knowledge, in the fact that this one should be in particular knowledge of the principle, the principle which we think of finding indicated, at Plato, under the expression “principle of the line”, dynamic and active, specifically not mathematical principle, always previous to any determination (size) – and, at the same time, to any enumeration – whatsoever.

A díade gestor-subordinado: as relações entre a compatibilidade dos valores humanos e o estado pessoal de qualidade de vida no trabalho / The manager-subordinate dyad: the relationship between the fit of human values and the personal state of quality of life at work.

Antonio, Fábio Alessandro Affonso 14 December 2011 (has links)
A relação entre a compatibilidade de valores e o bem-estar subjetivo tem sido identificada em alguns estudos. No entanto, menor atenção tem sido dada à compreensão da relação direta entre conflito de valores e qualidade de vida no trabalho, principalmente na relação diática entre gestores e subordinados. A teoria da troca entre líder e liderado prevê que o líder diferencia seus subordinados e, consequentemente, estabelece relações de natureza distinta com cada um deles. Para diferenciar os indivíduos da equipe o líder utiliza, dentre diversos critérios possíveis, a compatibilidade de características. Líderes e liderados que compartilham valores estabelecem interações de alta qualidade e essas interações geram resultados positivos para cada um dos membros da díade. Nesse sentido, este estudo questionou como seu problema fundamental: quais são as relações entre a compatibilidade diática dos valores dos gestores e de seus subordinados e o estado pessoal de qualidade de vida no trabalho desses gestores e subordinados? Pesquisar a relação da compatibilidade de valores e o estado pessoal de qualidade de vida no trabalho das pessoas, principalmente no caso da díade entre gestor e subordinado, pode promover uma melhor compreensão da dinâmica do comportamento organizacional. Isso posto, este estudo teve como objetivos (a) investigar a associação entre a compatibilidade dos valores pessoais dos subordinados e os valores sociais dos subordinados com relação aos seus gestores (compatibilidade subjetiva) e o estado pessoal de qualidade de vida no trabalho desses subordinados e (b) pesquisar a associação entre a compatibilidade dos valores pessoais de gestores e dos subordinados (compatibilidade objetiva) e o estado pessoal de qualidade de vida no trabalho desses gestores e subordinados. Para tanto, utilizou-se um questionário eletrônico autoaplicado administrado aos egressos da Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo. O questionário foi composto pelos instrumentos PVQ-21 para delimitação dos valores humanos e o BPSO-96 para o estado pessoal de qualidade de vida no trabalho de gestores e subordinados. A amostragem realizada foi não-probabilística obtida por conveniência, limitando a capacidade de generalização do estudo. Ademais, os dados foram analisados pela técnica de regressão polinomial para determinação das associações entre a compatibilidade dos valores na díade gestorsubordinado e as percepções sobre estado pessoal de qualidade de vida no trabalho. A partir dos resultados, é possível considerar que a compatibilidade de valores entre os membros da díade gestor-subordinado, seja pela ótica subjetiva ou objetiva, está associada à qualidade de vida no trabalho de gestores e subordinados, principalmente no conflito das dimensões autotranscendência e autopromoção da teoria de valores de Schwartz (1992). Finalmente, este estudo propõe a utilização conjunta dos índices de compatibilidade algébricos, modulares e quadráticos para a interpretação dos resultados de regressões sobre a compatibilidade de valores e outras variáveis, diferentemente do que a literatura sobre o tema sugere. Pelos resultados do estudo, os coeficientes dos três modelos não se contradisseram, de tal maneira que suas magnitudes e sinais se conservaram nos três casos. Além disso, as variáveis que entraram nos modelos foram semelhantes. Esse fato sinaliza para uma leitura conjunta dos três modelos que deverão produzir interpretações mais informativas que a análise de um modelo isolado. / The relationship between the fit of values and subjective well-being has been identified in past research. However, minor attention has been focused on understanding the direct relationship between conflicting values and quality of work life, especially in the managersubordinate dyad. The theory of leader-member exchange predicts that the leader differentiates his subordinates and thus establishes a distinctive relationship with each of them. To discern between individuals from his team the leader uses, among several possible criteria, the compatibility of features. Leaders and followers who share values establish high quality interactions, generating positive results for each member of the dyad. In this sense, this study questioned as its fundamental problem: what are the relationships between the dyadic compatibility of values of managers and their subordinates and the personal state of quality of work life of managers and subordinates? Studying this relationship, especially in the case of the dyad between manager and subordinate, can promote a better understanding of the dynamics of organizational behavior. That said, this study aimed to (a) investigate the association between the compatibility of subordinates\' personal values and social values (subjective fit) and their personal state of quality of work life, and to (b) investigate the association between the compatibility of the personal values of managers and subordinates (objective fit) and their personal state of quality of work life. For this purpose, a selfadministered electronic survey was sent to the alumni database of the Faculty of Economics, Administration and Accounting from the University of São Paulo. The questionnaire was composed of the instruments PVQ-21 for the definition of human values and BPSO-96 to the measurement of the perception of personal state of quality of work life of managers and subordinates. Sampling was carried out non-probabilistically, obtained by convenience, composing one of the limitations to the generalizability of the results of this study. Furthermore, the data were analyzed using polynomial regression to determine the associations between the compatibility of values in the manager-subordinate dyad and the perceptions of personal state of quality of life at work. From the results, it is possible to consider that the subjective and objective fit of values among members of the managersubordinate dyad is associated with their quality of work life, especially in the conflict dimensions of self-transcendence and self-enhancement from the value theory of Schwartz (1992). Finally, this study proposes the joint use of the algebraic, modular and quadratic indexes of compatibility for the interpretation of the results of regressions on studies of the compatibility of values and other variables, unlike the literature on the subject suggests. In this study, the coefficients of the three models do not contradict. Their magnitudes and signs were conserved in all three cases. In addition, the variables that entered the models were similar. This fact points to a joint reading of the three models so that interpretations of results should produce more informative scenarios than the analysis of an isolated model.

Métacaspases : cibles thérapeutiques contre le paludisme / Metacaspases : New Targets for Malaria Treatment

Sow, Fatimata 09 December 2016 (has links)
Le paludisme reste une des principales causes de mortalité infantile dans le monde tropical. L'émergence continue des résistances du parasite aux anti-paludiques constitue un sérieux problème de santé publique. La recherche de nouvelles cibles thérapeutiques, basée sur une connaissance plus approfondie des mécanismes moléculaires de la vie du parasite, est une nécessité permanente dans un paradigme de « reine rouge » qui s'applique parfaitement à la capacité d'adaptation du parasite. La découverte récente d'une métacaspase de Plasmodium falciparum (PfMCA1) et la mise en évidence de son rôle potentiel dans l'apoptose du parasite, fait qu'elle est une cible thérapeutique contre le paludisme. Dans le but de mieux approfondir les connaissances sur cette protéine cible, nous avons voulu, dans un premier temps, déterminer la structure tridimensionnelle de PfMCA1, afin de confirmer les différentes structures prédites in silico, et chercher de nouvelles molécules candidates par le docking moléculaire. Cependant cet objectif n'a pas pu être atteint, à cause d'un phénomène d'autoclivage de la protéine suite à son expression, ce qui fait que nous n'avons pas réussi à récupérer la protéine. Dans un second temps, nous avons étudié la métacaspase de Plasmodium vivax (PvMCA1) en comparaison avec PfMCA1, et nous avons montré que les résidus histidine et cystéine dans la dyade catalytique sont bien conservés. Nous avons identifié un deuxième site potentiel dans le domaine catalytique de PvMCA1. A partir d'échantillons collectés en Mauritanie, au Soudan et à Oman, nous avons montré que les résidus histidine et cystéine, ainsi, que les résidus du second site du domaine catalytique de PvMCA1 sont très variables. Les mutations de ces résidus doivent faire l'objet d'étude approfondie de leurs effets sur la fonction de la protéine PvMCA1. Ce polymorphisme trouvé dans les résidus catalytiques de PvMCA1, doit-être évalué comme marqueurs moléculaires de résistance / Malaria remains one of the main causes of infant mortality in the tropical world.The continuous emergence of parasite resistant to drug treatment is a serious threat to public health. Exploring new therapeutics targets based on depth knowledge on molecular mechanism of the parasite’s life is utmost needed in a paradigm of « red queen», which applies perfectly on the ability of the parasitic adaptation. The recent discovery of metacaspase of Plasmodium falciparum (PfMCA1) and the demonstration of its potential role in apoptosis, make it a therapeutic target against malaria. In order to increase knowledge about this protein, we planned, to determine the three-dimensional structure of PfMCA1, to confirm the different structures predicted in silico, and to look for new drug using molecular docking. However, this goal was not reached, since autoprocessing occurred during expression, and we failed to obtain the full-length protein. Then we studied the metacaspase of Plasmodium vivax (PvMCA1) in comparison with PfMCA1 and, we shown that histidine and cysteine residues in the dyad catalytic are well conserved. We have identified a second potential site in the catalytic domain of PvMCA1. We shown that residues in both putative sites are highly polymorphic in samples from Mauritania, Sudan and Oman. Mutations on these residues need to be deeply studied for their effects on the PvMCA1 function. This polymorphism found in catalytic residues of PvMCA1should be evaluated as new molecular marker of resistance

Measuring cognitive load management in a traditional martial arts training model

Maier, Herbert N. 29 August 2005 (has links)
A training method utilized in a few martial arts was found to agree strongly with current cognitive psychology theory. Further study extracted a procedural model for learning a complex set of whole-body, dyadic motor skills involving high-speed, interactive, continuous situation assessment and decision making. A broader literature survey found relevance in several fields of research, supporting the definition of four performance dimensions in the activity. Data collected from one experienced student partnering with each of ten students of various experience levels was analyzed on these four dimensions. These dimensions were found sufficient to show both individual differences and changes across an instructional intervention. Strong correlations found under linear regression were supportive of anecdotal evidence from the model??s long empirical history in training. Data provided evidence of a self-organizing dynamic emerging from the interaction of a dyad participating in this activity, and of individual differences in cognitive resource management dynamically setting allocation priorities among specific aspects of a complex motor/cognitive activity. Highly individual responses demonstrate a mechanism for insight into students that are difficult to read. Numerous comparisons and contrasts show interactivity of performance dimensions. Impact is foreseen for research, training and testing in motor learning fields, as well as situation awareness, decision making and military tactical training. Further research is recommended to replicate these findings, test hypotheses derived from them, and to extend testing of the drill-network model into other fields of learning.

Janine Antoni: Finding a Room of Her Own

Lindner, Stacie M. 04 December 2006 (has links)
Janine Antoni's object- and performance-based works draw from multiple influences including feminism and conceptualism, and in these works the artist has fashioned an investigation of the self through the examination of the mother/child dyad, creating a more than fourteen-year body of work about these relationships that explore the implications of feminine imagery. Antoni’s works are an effort to distinguish her body as a feminine subject-object, but also to identify with as well as separate herself from the mother. While she is a conceptual artist, Antoni puts great emphasis on materiality. For her, the concept defines itself within the materials, and it is the process of the making that interests her most, empowering what is traditionally overlooked, forgotten, or disempowered. As she alternately separates from and connects with the mother and the foremothers of the artistic heritage that have surely contributed to establishing this identity, Antoni allows new images of the female to be made visible in a culture where they have traditionally been lacking.
