Ordres professionnels et ordre concurrentiel / Professional order and compétitive order

Castelot, Pauline 16 December 2016 (has links)
Les Ordres professionnels ont pour objectif d'organiser certaines professions qui nécessitent un encadrement particulier, tant dans leur accès que dans leur exercice. A travers cette organisation, l'Ordre va avoir pour mission de veiller sur la profession libérale et sur ses intérêts. Le développement de l’exercice de cette dernière sur le marché va opposer les règles édictées par l’Ordre professionnel aux règles organisant le marché, composant l’Ordre concurrentiel. A travers cette étude, il convient donc de s'interroger sur la pertinence du rôle de l'Ordre professionnel face au droit de la concurrence et sur sa place au sein d'un ordre concurrentiel sur le marché. Ainsi, la problématique suivante peut être soulevée : la reconnaissance des ordres professionnels peut-elle s'inscrire dans une politique de concurrence ? Autrement dit, les ordres professionnels peuvent-il s'adapter à un objectif concurrentiel et se soumettre au droit de la concurrence ? L’existence de deux Ordres, un Ordre professionnel et un Ordre concurrentiel, au sein du marché va entrainer une étude croisée des schémas d’organisation ainsi que de leurs influences réciproques. C’est à l’issue de cette confrontation qu’émergera une redéfinition de l’Ordre professionnel et de ses pouvoirs afin de permettre aux professionnels organisés en institution ordinale de concilier au mieux les intérêts éthiques et les problématiques concurrentielles. / The purpose of professional associations is to regulate access and practice of particular professions. Through this organization, interests of independent professions are protected. Then, such rules overthrow and may breach competition law.Accordingly, this PhD underlines hurdles that professional associations can encounter on a competitive market. The question is to know under which circumstances and conditions professional associations must abide by competition policy.Furthermore, the study of both bodies of rules will shed the light on the influence they can have on each other. This will enable to define more properly professional associations and their powers in order to accommodate professional ethics with competition.

Dissertation on competitive and directed search / Thèse en recherche concurrentielle et recherche dirigée

Bi, Sheng 04 December 2015 (has links)
Nous prenons l’approche d’annonce des salaires avec la recherche d’emploi à étudier trois problèmes dans le marché du travail. Le premier problème concerne l’arrêt de travail prématuré des travailleurs. Tel arrêt de travail prématuré crée des risques de chiffre d’affaires pour les entreprises, donc les entreprises veulent proposer des profils de salaire pour minimiser ces risques. Dans ce problème, l’asymétrie de l’information joue un rôle important. Nous adoptons une approche du mécanisme design et considérons les différents timings auxquels l’information privée est réalisée. Dans un papier de suivi, nous proposons une politique d’Age spécifique par laquelle cette inefficacité peut être atténuée, et étudions son implication sur le bien-être et la production globale. Dans le deuxième problème, nous revisitons l’analyse du bien-être de l’impact de la discrimination sur le choix des compétences sous une norme d’embauche multidimensionnelle le long des caractéristiques qui sont soit liées à la productivité soit indépendantes de la productivité. Nous montrons comment l’investissement de compétences stratégique entre le groupe favorise et discrimine se pose. Nous comparons également deux mécanismes de détermination des salaires (salaire annoncé et négocié) pour vérifier la robustesse de résultats. Dans le troisième problème, nous considérons dans quelle mesure l’allocation de chômage et le salaire minimum peuvent corriger les répartitions inefficaces découlant du pouvoir de marche des firmes. Notre contexte concerne les petits marchés ou le ratio travailleurs/firmes ne soit pas grand. L’imperfection de marche vient du fait qu’au marché du travail à petite échelle les firmes paient un niveau de salaire moins que le niveau compétitif. Nous procédons à partir d’un point de vue d’organisation industrielle, et proposons en se concentrant sur la mauvaise répartition d’emploi et de surplus lors de l’analyse de l’efficacité de l’instrument de la politique. / We take the wage posting approach with search friction to study three issues in labor market. The first issue concerns the premature quitting of workers. Our framework is suitable for contexts such as disability shock, retirement, maternity leaves etc. Such premature quitting creates turnover risks for firms, hence the firms propose wage profiles to minimize or avoid it. In this issue, the asymmetric information plays an important role. We adopt an approach of mechanism design and consider different timings at which the private information is realized. In a follow-up paper, we propose an age-directed policy by which this inefficiency can be alleviated and study its implication on welfare and aggregate output. In the second issue, we revisit welfare analysis of impact of discrimination on skill choice under a multi-dimensional hiring norm along both productivity-related and -unrelated characteristics. We show how strategic skill investment between favored and discriminated group arise. We compare also two wage determination mechanisms (posted and bargained wage). In the third issue, we consider to which extent can the roles of unemployment benefit and minimum wage correct inefficient allocations arising from firms’ market power. Our context concerns small markets where the workers/firms ratio is not large. The market imperfection comes from the fact that in such a small market firms pay less than competitive level of wages. We proceed from an industrial organizational perspective and suggest focusing on both misallocation of labor and surplus when analyzing the effectiveness of the policy instrument.

Effets cumulatifs et compétitifs des éléments chimiques sur l’altération des verres nucléaires / Cumulative and competitive effects of chemical elements on nuclear glass alteration

Arena, Hélène 26 February 2016 (has links)
Cette thèse s’inscrit dans l’étude du comportement à long terme des verres nucléaires en conditions de stockage. Son objectif est de déterminer, de comprendre et de comparer les effets de certains éléments chimiques présents dans la composition du verre et/ou dans le milieu de stockage (Zn, Mg, Ni, Co, Fe, Ca, Gd, Ce, K, Cs, Cr et Ag) sur les différents processus mis en jeux lors de l’altération aqueuse des verres nucléaires. Dans ce cadre, une attention particulière a été portée sur le caractère cumulatif ou compétitif des effets de ces éléments chimiques. Pour cela, un verre simple à 6 oxydes (ISG) a été altéré pendant plus de 500 jours dans une solution contenant un ou plusieurs des éléments chimiques d’intérêt. Les éléments Zn, Mg, Ni, Co et Fe augmentent l’altération du verre en formant des phases secondaires de même structure (smectites tricotaédriques) et de même stœchiométrie (à l’élément près). Leur précipitation consomme des éléments chimiques du milieu (Si, Al) et induit une diminution de pH. Ce processus se maintient jusqu’à l’atteinte d’un pH limite propre à chaque phase secondaire, au-dessous duquel leur précipitation est inhibée. Par la suite, ces éléments peuvent s’intégrer dans le gel d’altération en remplacement du Ca rendu plus soluble par la baisse du pH. Tant qu’ils forment des phases secondaires, les effets de ces éléments sont cumulatifs. Les terres rares Gd et Ce augmentent aussi l’altération du verre en formant des phases secondaires mais leurs effets sont plus faibles car elles sont moins silicatées. Ces éléments, ne s’intègrent pas dans le gel. Le Cr précipite avec le Ca pour former une phase qui appauvrit le gel en Ca, entraine une diminution du pH et augmente l’altération du verre.Les éléments K, Cs et Ca limitent l’altération du verre en s’intégrant dans le gel et en ralentissant les phénomènes de transport en son sein. Cette intégration est compétitive : l’ordre d’intégration (quantité et efficacité sur la limitation de l’altération) est le suivant Ca >> Cs > K. L’élément Ag précipitant sous forme d’AgCl, n’a pas d’effet sur l’altération du verre : cette phase ne modifie ni le milieu, ni le développement de la pellicule d’altération.Ainsi, l’augmentation de l’altération pourrait être proportionnelle à la quantité d’éléments favorisant la précipitation de phases secondaires, mais la diminution de pH qui l’accompagne limite ce processus. Les effets des éléments qui diminuent l’altération du verre en s’incorporant dans le gel, sont limités en quantité par la composition du gel et sa capacité à les recevoir, et en qualité par la nature même des éléments. / This work takes place in the context of the long-term behavior of nuclear glasses under repository conditions. The main objective is to identify, understand and compare the effects of some chemical elements present in the glass composition and/or in the repository media (Zn, Mg, Ni, Co, Fe, Ca, Gd, Ce, K, Cs, Cr and Ag) on the processes involved in glass alteration by water. The cumulative or competitive nature of the effects of these chemical elements was determined. To reach this goal, a 6 oxides simple glass (ISG) has been altered for more than 500 days in a solution containing one or more of the chemical elements of interest.The results indicated that Zn, Mg, Ni, Co and Fe elements increase glass alteration forming secondary phases with the same structure and stoichiometry (trioctahedral smectites). To form, these silicates consume chemical elements (Si, Al) from the environment and induce a pH decrease until a limiting value of pH. Beyond this pH the precipitation of secondary phases is inhibited and these chemical elements can be integrated into the gel, replacing Ca whose solubility increases at lower pH. As long as they form secondary phases, the effects of these elements are cumulative. Rare earths Gd and Ce also increase glass alteration forming secondary phases but their effects are lower as they contain less silicon. These elements are not integrated in the gel. Chromium increases glass alteration by precipitating with Ca and leading to a less protective gel, depleted in Ca. Silver precipitates as AgCl and has no effect on the alteration of the glass.The chemical elements K, Cs and Ca limit glass alteration by integrating into the gel and slowing down the transport phenomena therein. This integration is competitive: the order of integration (quantity and effectiveness glass alteration limitation) is the following Ca >> Cs > K. Thus, the increase of glass alteration may be proportional to the quantity of elements promoting the precipitation of secondary phases, but the pH decrease limits the process. The effects of the elements that reduce glass alteration by incorporating into the gel, are quantitatively limited by the gel composition and its ability to incorporate them, and qualitatively by the nature of the elements.

Self service business intelligence : Grundkompetenser för slutanvändare / Self service business intelligence : Basic competencies for end users

Johansson, Christoffer January 2018 (has links)
Organisationer vill hela tiden bli effektivare i allt de gör även när det kommer till business intelligence. För att effektivisera beslutstödsprocessen har organisationer börjat gå över till selfe service business intelligence där personer på en operativ nivå skapar sina egna rapporter och gör sina egna analyser. När detta sker uppkommer nya moment för personalen i organisationen och de behöver skaffa sig nya kompetenser. Vilka kunskaper behöver egentligen personalen skaffa sig? Det är det som undersöks i det här arbetet. Undersökningen kommer genomföras med hjälp av en fallstudie. Litteratur kommer att granskas och intervjuer kommer att genomföras med personer som arbetar med beslutstöd. Arbetet undersöker vilka kompetenser som krävs av en slutanvändare men exkluderar hur de skaffar sig dessa kompetenser. Resultatet visar att det finns tre stycken huvudkategorier av kompetenser dessa är tekniska kunskaper, verksamhetskunskaper och analytiska förmågor. Under dessa kategorier finns sedan sex stycken kompetenser; Verksamhetsdata, BI-verktyget, Datavana, Verksamheten, Branschkunskap och Analytisktänk.

Self-service business intelligence : Viktiga Roller inom SSBI / Self-service business intelligence : Important roles in SSBI

Leo, Gustav January 2017 (has links)
Dagens affärsklimat är under ständig utveckling och för att möta den ökade konkurrensen är det viktigt för verksamheter att snabbt kunna fatta beslut som är baserade på data. Utmaningarna i detta medför att verksamheternas arbetssätt måste bli mer innovativt för att snabbare kunna anpassa verksamheten. Traditionell business intelligence (BI) där IT-avdelningen oftast ansvarar för att ta fram rapporter åt användarna har svårt att hinna med att skapa rapporter som är nödvändiga för att fatta beslut grundade i data. En lösning på detta problem är att införa Self-Service BI (SSBI) där målet är att låta användarna komma närmre verksamhetens data och på det sätta kunna skapa rapporter utan inblandning från IT-avdelningen. Genom att ta bort IT-avdelningen som mellanhand och flytta ut visst ansvar på verksamhetens avdelningar ställs krav på en tydlig organisation med tydliga roller och detta ligger till grund för den frågeställning som denna studie ska ge svar på som är: Vilka roller krävs för att införa och driva SSBI? Metoderna som valts ut för att kunna ta fram ett svar på denna fråga är systematisk litteraturstudie och fallstudie. Syftet med att genomföra den systematiska litteraturstudien är att analysera vad den befintliga litteraturen tar upp om roller inom SSBI. Fallstudien som består av intervjuer med experter inom SSBI-området syftar till att fånga upp deras erfarenheter och åsikter om det olika roller som är viktiga inom SSBI. Resultatet består av ett framtaget organisationsschema över viktiga roller som behövs för att kunna införa och driva SSBI inom en verksamhet.

Utvärdering av Business Intelligence system ur ett nytto-perspektiv : En studie om hur företag kan utvärdera nyttan av ett Business Intelligence system före och efter en implementation

Andriesse, Carin, Edvinsson, Erika January 2016 (has links)
Den ökade mängden data i världen leder till att allt fler företag väljer att investera i BI-system som kan stödja hantering och analys av data. Genom att analysera data kan det leda till nytta för företaget som exempelvis bättre kontroll och beslutsunderlag. Samtidigt har utvärderingen av nyttan med systemen inte följt med i samma utveckling som investeringarna. Svårigheten att utvärdera de mjuka och strategiska nyttorna med ett BI-system är en av anledningarna till det. Genom att utvärdera ett BI-system kan företag få en uppfattning av vilka nyttor som uppnåtts och om ytterligare aktiviteter krävs för att öka nyttan. En kvalitativ intervjustudie har utförts på stora tillverkande företag och konsultföretag för att se hur arbetet med utvärdering av nyttor med BI-system går till i praktiken. Studien inkluderar utvärdering både innan och efter en implementation och resulterar i rekommendationer. Studiens resultat visar att det kan skilja sig hur små företag och stora tillverkande företag använder BI-systemet och därmed hur utvärdering bör ske. Det har även påvisats att det bör ske ökad utvärdering efter att BI-systemen införts i företaget. Genom att inkludera utvärdering av delar som påverkar möjligheten att uppnå nytta, såväl som delar som kan påverka utvärderingen, leder det till en mer realistisk utvärdering och därmed en större chans för företag att öka nyttan med sitt BI-system. / The growing amount of data in the world leads to an increasing amount of investments in BI-systems, which can support management and analysis of data. Businesses can experience benefits such as better control and decision base when they analyze their data. The evaluation of BI-systems has fallen behind at the same time as investments in these systems has increased. The difficulty in evaluating the soft and strategic benefits of a BI-system is one of the reasons for the lack of evaluations. Evaluation can give businesses a notion of which benefits that they have achieved and if further activities are needed to increase the benefits of the BI-system. A qualitative interview study has been carried out on large manufacturing businesses and consulting businesses, with the purpose to study how the evaluation of BI-system benefits are being done in practice. The study include evaluation before and after an implementation of a BI-system and results in recommendations. The result of the study shows that there can be differences in the way small and large manufacturing businesses use the BI-system and therefore also differences in how to perform the evaluation. The study has also established that more evaluations should be done after the BI-system has been implemented. Evaluation of parts that affect the possibility to achieve benefits as well as parts that affects the evaluation results in a more realistic evaluation, and a greater chance for the business to increase the benefits of their BI-system.

Business Intelligence em redes hoteleiras no Brasil / Business Intelligence in hotel chains in Brazil

Rubio, Mariana Consoni 30 March 2016 (has links)
Em um momento em que a produção de conhecimento é cada vez mais necessária junto à contínua expansão e diversificação dos meios de hospedagem, torna-se interessante investigar o recém-criado campo de Inteligência de Negócios ou Business Intelligence (BI). Na hotelaria, as tecnologias e os sistemas de informação são empregados em diversas áreas, como gestão, política de preços, programação e operação de sistemas de informações estratégicas, a fim de facilitar as análises dos principais indicadores de desempenho do setor. A preocupação gira em torno da elevada quantidade de informações produzidas, sendo fundamental dispor de uma maior precisão em processos de tomada de decisões. Nesse contexto, propõe-se um estudo com enfoque no tema Inovação em gestão hoteleira no Brasil, com o objetivo geral de analisar a gestão da inteligência de negócios das redes hoteleiras que atuam no Brasil. Trata-se de uma pesquisa de caráter qualitativo, baseado em revisão de literatura e aplicação de questionários junto aos gestores das redes hoteleiras, podendo, assim, mapear as necessidades das cadeias hoteleiras em termos de gestão, ao se avaliar as práticas de BI. Como resultados, foram identificados os principais softwares de BI existentes no mercado brasileiro (Cognos, MicroStrategy, SAS, Business Objects, Oracle Business Intelligence, QlikView e Pentaho) e os mais adequados para cada porte de empresa. Também foram identificadas as soluções utilizadas para a gestão da informação de BI pelas redes: emprego de softwares de BI, terceirização por meio de serviços de consultoria e tratamento manual dos dados dos sistemas dos hotéis. Por fim, foram avaliados os resultados da gestão de BI nas redes, concluindo que a implantação de gestão de BI considerando a gestão da informação atrelada às TIs traz mais benefícios do que custos às redes hoteleiras analisadas, sobretudo no que diz respeito a propiciar uma tomada de decisão mais acertada / In a time when the production of knowledge is increasingly required for the continued expansion and diversification of lodging facilities, it is interesting to investigate the newly created Intelligence field of Business or Business Intelligence (BI). In hospitality, technology and information systems are used in various fields such as management, pricing, scheduling and operation of strategic information systems to facilitate analysis of key industry performance indicators. The concern revolves around the vast amount of information produced and it is essential to dispose of greater accuracy in decision-making processes. In this context, is proposing a study focusing on the theme Innovation in hotel management in Brazil, with the overall objective to analyse the management of the business intelligence of the chains operating in Brazil. It is a qualitative research, based on literature review and application of questionnaires with the managers of the chains, and thus can map the needs of hotel chains regarding management when evaluating BI practices. As a result, the primary existing BI software in the Brazilian market was identified (Cognos, MicroStrategy, SAS, Business Objects, Oracle Business Intelligence, QlikView, and Pentaho) and the most suitable for every size company. Also, the solutions identified were used for the management of BI information across networks: use of BI software, outsourcing through consultancy and manual data processing systems of the hotel services. Finally, it was evaluated the BI management achievements in the nets, concluding that the BI management implementation - considering the information management linked to IT - bring more benefits than costs to the analysed chains, particularly about providing a more positive decision making

Sucesso de sistemas de Business Intelligence: uma abordagem multidimensional. / Business intelligence systems sucess: a multidimensional approach.

Aristizabal, Catalina Ramirez 09 May 2016 (has links)
Assim como outros investimentos em tecnologia da informação, os sistemas de Business Intelligence (BI) também têm sido questionados em relação aos benefícios e retornos obtidos depois de sua implantação. Isso porque o produto de BI é inteligência, ou, em outras palavras, algum tipo de informação processada, e o valor da informação é difícil de avaliar. A presente pesquisa pretende contribuir ao estudo desse problema de pesquisa, abordando o tema da avaliação dos sistemas de BI por meio do modelo de sucesso de sistemas de informação proposto por DeLone e McLean. Além das dimensões tradicionais inter-relacionadas do modelo: capacidade de BI, qualidade da informação, satisfação dos usuários e nível de uso, foi incluída a variável a abordagem de decisão, pois um dos principais objetivos dos sistemas de BI é processar dados advindos de diferentes fontes, para produzir informação que sirva como suporte para a tomada de decisão. Uma vez que a capacidade de BI e a qualidade da informação são constructos multidimensionais, uma das contribuições desta pesquisa foi realizar um levantamento na literatura sobre as dimensões que operacionalizam esse constructo e avaliá-las empiricamente. A capacidade de BI foi definida em termos de acessibilidade, capacidades analíticas, flexibilidade e integração, e qualidade da informação em termos de atualidade, completude, oportunidade e precisão. O problema de pesquisa foi abordado por meio da metodologia de survey, em que os respondentes foram convidados a participar da pesquisa via e-mail e o questionário foi disponibilizado em forma eletrônica através da ferramenta SurveyMonkey. No total, foram obtidas 483 repostas, das quais 246 foram válidas. Já que o modelo conceitual proposto inclui múltiplas relações de interdependência, a técnica estatística selecionada para analisar os dados foi a modelagem de equações estruturais. O software utilizado foi o SmartPLS que testa o modelo estrutural por meio do método de mínimos quadrados ordinários. Foi possível comprovar empiricamente todas as relações de causalidade propostas entre as dimensões de sucesso dos sistemas de BI, a exceção da relação de moderação da variável abordagem de decisão na relação de causalidade entre satisfação e nível de uso. Um teste subsequente permitiu observar que essa variável poderia ser preditora do nível de uso. Segundo os resultados, é possível afirmar que o sucesso de BI pode ser definido em termos da capacidade de BI, qualidade da informação, satisfação dos usuários e nível de uso. A operacionalização realizada dos constructos multidimensionais \"capacidade de BI\" e \"qualidade da informação\" poderia dar luzes sobre quais características devem ser priorizadas na implantação e/ou desenvolvimento dos sistemas de BI nas empresas. / As well as other investments in Information Technology (IT), Business Intelligence (BI) systems have also been questioned in relation to the benefits and returns obtained after its implementation. These questions arise because the BI product is intelligence, or, in other words, some kind of processed information and the value of information is difficult to assess. This research aims to contribute to this by addressing the issue of evaluation of BI systems through the information systems success model proposed by DeLone and McLean, beyond the traditional dimensions that are interrelated: BI capabilities, quality of information, user satisfaction, and level of use. The decision approach was included as a variable since a key objective of BI systems is to process data coming from different sources to produce information that serves as a basis for the decision-making process. Once the BI capability and information quality are multidimensional constructs, one of the contributions of this study was to review the literature available about the dimensions that operationalize this construct and evaluate them empirically. BI capability was defined in terms of accessibility, analytical capabilities, flexibility and integration, and the information quality in terms of opportunity, completeness, timeliness and accuracy. The research problem was addressed by the survey methodology: the respondents were invited to participate in the survey via email and the questionnaire was made available in electronic form through the SurveyMonckey tool. A number of 246 responses were usable out of the 483 total responses that were obtained. Since the proposed conceptual model includes multiple interdependencies, the statistical technique selected to analyze the data was the structural equation modeling. The software used was the SmartPLS, which tests the structural model using the ordinary least squares method. It was possible to prove empirically all the causal relationships proposed between success dimensions of BI systems, except for the moderation effect of making-decision approach variable on the relationship between satisfaction and usage level. A subsequent test allowed us to observe that this variable could be a predictor of the level of use. According to these results, we can say that the success of BI can be defined in terms of BI capability, the quality of information, user satisfaction and the level of use. The operationalization of the variables BI capability and information quality as a multidimensional construct could enlighten the decision about which features should be prioritized in implementing the development of BI systems in companies.
