Mesure de la performance dans les organisations de réadaptation en déficience physique

Zidarov, Diana 08 1900 (has links)
La présente thèse vise à évaluer le degré d’implantation et d’utilisation de systèmes de mesure de la performance (SMP) par les décideurs des organisations de réadaptation et à comprendre les facteurs contextuels ayant influencé leur implantation. Pour ce faire, une étude de cas multiples a été réalisée comprenant deux sources de données: des entrevues individuelles avec des cadres supérieurs des organisations de réadaptation du Québec et des documents organisationnels. Le cadre conceptuel Consolidated Framework for Implementation Research a été utilisé pour guider la collecte et l’analyse des données. Une analyse intra-cas ainsi qu’une analyse inter-cas ont été réalisées. Nos résultats montrent que le niveau de préparation organisationnelle à l’implantation d’un SMP était élevé et que les SMP ont été implantés avec succès et utilisés de plusieurs façons. Les organisations les ont utilisés de façon passive (comme outil d’information), de façon ciblée (pour tenter d’améliorer des domaines sous-performants) et de façon politique (comme outil de négociation auprès des autorités gouvernementales). Cette utilisation diversifiée des SMP est suscitée par l’interaction complexe de facteurs provenant du contexte interne propre à chaque organisation, des caractéristiques du SMP, du processus d’implantation appliqué et du contexte externe dans lequel évoluent ces organisations. Au niveau du contexte interne, l’engagement continu et le leadership de la haute direction ont été décisifs dans l’implantation du SMP de par leur influence sur l’identification du besoin d’un SMP, l’engagement des utilisateurs visés dans le projet, la priorité organisationnelle accordée au SMP ainsi que les ressources octroyées à son implantation, la qualité des communications et le climat d’apprentissage organisationnel. Toutefois, même si certains de ces facteurs, comme les ressources octroyées à l’implantation, la priorité organisationnelle du SMP et le climat d’apprentissage se sont révélés être des barrières à l’implantation, ultimement, ces barrières n’étaient pas suffisamment importantes pour entraver l’utilisation du SMP. Cette étude a également confirmé l’importance des caractéristiques du SMP, particulièrement la perception de qualité et d’utilité de l’information. Cependant, à elles seules, ces caractéristiques sont insuffisantes pour assurer le succès d’implantation. Cette analyse d’implantation a également révélé que, même si le processus d’implantation ne suit pas des étapes formelles, un plan de développement du SMP, la participation et l’engagement des décideurs ainsi que la désignation d’un responsable de projet ont tous facilité son implantation. Cependant, l’absence d’évaluation et de réflexion collective sur le processus d’implantation a limité le potentiel d’apprentissage organisationnel, un prérequis à l’amélioration de la performance. Quant au contexte externe, le soutien d’un organisme externe s’est avéré un facilitateur indispensable pour favoriser l’implantation de SMP par les organisations de réadaptation malgré l’absence de politiques et incitatifs gouvernementaux à cet effet. Cette étude contribue à accroître les connaissances sur les facteurs contextuels ainsi que sur leurs interactions dans l’utilisation d’innovations tels les SMP et confirme l’importance d’aborder l’analyse de l’implantation avec une perspective systémique. / This thesis aims to assess the degree of implementation and use of performance measurement systems (PMS) by decision makers in rehabilitation organizations and to understand the contextual factors that influenced their implementation. A multiple case study was conducted using two data sources: individual interviews with senior executives in rehabilitation organizations from the province of Quebec and organizational documents. The Consolidated Framework for Implementation Research was used to guide the collection and analysis of data. Intra-case analysis and a cross case analysis were conducted. Our results show that organisational readiness for PMS implementation was high and that the PMS was successfully implemented and used in several ways, based on organizational needs. Organizations used them passively (as an information tool), purposefully (to act on underperforming areas) and politically (for negotiating with government authorities). This diverse use of PMS is the result of complex interactions between factors from the internal context of each organization, PMS characteristics, the implementation process and the external environment in which these organizations operate. Within the internal context, the continued commitment and leadership of senior management were decisive in implementing the PMS through their influence on the identification of the need for a PMS, users’ engagement, organizational priority given to the PMS, resources allocation to its implementation, quality of communications and organizational learning climate. However, even if factors such as resources allocated to the implementation, organizational priority of the PMS and the learning climate were found to be barriers to its implementation, ultimately, these barriers were not important enough to hinder PMS use. This study also confirmed the importance of PMS characteristics, particularly the perception of quality and usefulness of the information. However, by themselves, these characteristics are insufficient to ensure implementation success. This implementation analysis also revealed that although the implementation process did not follow formal stages, a PMS development plan, participation and commitment of decision makers and the appointment of a project leader all facilitated implementation of the PMS. However, the lack of evaluation and collective reflection on the implementation process limited the potential for organizational learning, a prerequisite for performance improvement. As for the external context, the support of an external organization proved to be an essential enabler for PMS implementation by rehabilitation organizations despite the absence of governmental policies and incentives to do so. This study contributes to increasing knowledge about the contextual factors and their interactions in the implementation of innovations such as PMS and confirms the importance of addressing implementation analysis with a systemic perspective.

雙人決策秘書問題的研究 / A Variation of Two Decision Makers in a Secretary Problem

周冠群, Chou, Guan-Chun Unknown Date (has links)
Chen, Rosenberg和Shepp(1997)的“雙人決策者的秘書問題“(A Secretary Problem with Two Decision Makers),探討在完整訊息(Full Information)與選擇次序不變的情況下,具有優先選擇權的決策者佔有較大優勢。這裡所謂的優勢意指在雙方最終選擇的大小為勝負條件所產生獲勝機率的比較。而本篇文章主要是延伸此一探討,意即在若不變動兩者選擇的次序,但賦予後選擇決策者較多資訊的條件下,能否平衡雙方的優劣勢。我們首先討論後決策者擁有預知下一步(One-step look-ahead)資訊能力的條件下,雙方優勢的改變;隨之若是在後決策者能預知完全資訊的情況下,是否能平衡雙方的優劣勢。而事實上,即便在後決策者擁有所有資訊的條件,仍無法完全改變此一情況;更進一步而言,先選擇決策者甚至在不知道後決策者已掌握了所有資訊的情況下,仍可佔有獲勝機率大於後決策者的優勢。這裡我們將提供理論與理論上的數值結果。 / Chen, Rosenberg, and Shepp (1997) considered a variation of the "secretary problem" in which the salary demands of a group of applicants are from a known and continuous distribution (i.e., full information case) and these applicants are interviewed sequentially by two managers, say, I and II. For every applicant. Manager I has the right to interview and hire him/her first. If Manager I rejects the applicant, Manager II can interview him/her. No recall is allowed when the applicant is rejected by both managers, and neither manager can interview and hire another applicant once he/she has hired an applicant. The manager who chooses the applicants with the lower salary wins the game. Chen et al. shows that manager I has bigger winning chance than manager II in the full information case. This study is to extend the paper by Chen et al., by giving extra information to manager H. In particular, suppose that manager II can look a few applicants ahead, i.e., he/she knows the salary demands of applicants before manager I interview them. However, under the full-information assumption, even if manager II is a clairvoyant, who claims to be able to see what will happen in the future, his/her winning probability is still less than that of manager I. We provide theoretical proof and simulation to confirm this result.

Competitive intelligence with specific reference to the challenges facing the Competitive Intelligence Professional in South Africa

Odendaal, Bernardus Johannes 09 February 2005 (has links)
Natural tension exists between decision-makers and intelligence professionals. The main problems involve control over the gathering, interpretation, presentation, and the use of intelligence products in the decision-making process. Competitive intelligence (CI) professionals are rarely in a management position, and few managers and decision-makers have the necessary understanding of the value of intelligence products and thus intelligence is often misused or discarded. This situation results in intelligence failures and inappropriate strategic decisions by management. The methodology for the study was to determine the perceptions of CI professionals with regard to the current state of affairs of the CI function in the private sector. The study was conducted among members (n=74) of the South African Association of Competitive Intelligence Professionals. An overview of the development of CI within the South African context was also done, and interviews with key personalities practising CI in South Africa were conducted. The results indicated that many issues and challenges still face the CI professional in the South African environment, such as control over intelligence and the way in which it is used. There is a worrying tendency of third parties gathering intelligence, resulting in a situation where plausible denial is possible. Management perception/ignorance of the capabilities of intelligence in the decision-making process still needs to be addressed. There is also a need for recognition among CI professionals with regard to standards and representation. The CI field is still almost exclusively a male-dominated industry, with high barriers of entry in terms of academic qualifications. The conclusions are that a greater understanding of the requirements and needs of decision-makers, with regard to intelligence products, should be created. Decision-makers also need to understand the limits of intelligence products, and that intelligence products can only be compiled from information that has been gathered in a legal and ethical way. CI professionals have the responsibility to develop an indigenous body of knowledge as a means of making CI an accepted business practice and an indispensable tool in management decision-making. / Dissertation (M (Security Studies))--University of Pretoria, 2006. / Political Sciences / unrestricted

Développement d'une approche floue multicritère d'aide à la coordination des décideurs pour la résolution des problèmes de sélection dans les chaines logistiques / Multi-criteria group decision making approach for the selection problem

Igoulalene, Idris 02 December 2014 (has links)
Dans le cadre de cette thèse, notre objectif est de développer une approche multicritère d'aide à la coordination des décideurs pour la résolution des problèmes de sélection dans les chaines logistiques. En effet, nous considérons le cas où nous avons k décideurs/experts notés ST1,...,STk qui cherchent à classer un ensemble de m alternatives/choix notées A1,...,Am évaluées en termes de n critères conflictuels notés C1,..., Cn. L'ensemble des données manipulées est flou. Chaque décideur est amené à exprimer ses préférences pour chaque alternative par rapport à chaque critère à travers une matrice dite matrice des préférences. Notre approche comprend principalement deux phases, respectivement une phase de consensus qui consiste à trouver un accord global entre les décideurs et une phase de classement qui traite le problème de classement des différentes alternatives.Comme résultats, pour la première phase, nous avons adapté deux mécanismes de consensus, le premier est basé sur l'opérateur mathématique neat OWA et le second sur la mesure de possibilité. De même, nous avons développé un nouveau mécanisme de consensus basé sur la programmation par but goal programming. Pour la phase de classement, nous avons adapté dans un premier temps la méthode TOPSIS et dans un second, le modèle du goal programming avec des fonctions de satisfaction. Pour illustrer l'applicabilité de notre approche, nous avons utilisé différents problèmes de sélection dans les chaines logistiques comme la sélection des systèmes de formation, la sélection des fournisseurs, la sélection des robots et la sélection des entrepôts. / This thesis presents a development of a multi-criteria group decision making approach to solve the selection problems in supply chains. Indeed, we start in the context where a group of k decision makers/experts, is in charge of the evaluation and the ranking of a set of potential m alternatives. The alternatives are evaluated in fuzzy environment while taking into consideration both subjective (qualitative) and objective (quantitative) n conflicting criteria. Each decision maker is brought to express his preferences for each alternative relative to each criterion through a fuzzy matrix called preference matrix. We have developed three new approaches for manufacturing strategy, information system and robot selection problem:1. Fuzzy consensus-based possibility measure and goal programming approach.2. Fuzzy consensus-based neat OWA and goal programming approach.3. Fuzzy consensus-based goal programming and TOPSIS approach.Finally, a comparison of these three approaches is conducted and thus was able to give recommendations to improve the approaches and provide decision aid to the most satisfying decision makers.

Klimatanpassa marksanering : Förbättringsförslag för ökad tillämpning av biologiska marksaneringsmetoder / Climate-adapt soil remediation : Suggestions for improvements of increased application of biological soil remediation methods

Borefur, Christoffer, Berggren, Emma January 2020 (has links)
Purpose: In Sweden, there are area that are polluted and in need of remediation. However, soil remediation processes have a negative secondary impact on the climate. There are various soil remediation methods to apply, of which dig and dump are the most frequently used. The method involves although high emissions of carbon dioxide. By increased use of alternative soil remediation methods, such as biological soil remediation methods, can lead to reduced impact on the climate. When choosing a remediation method, sustainability is increasingly integrated, but most decisions are still based on other factors. Psychological, social and institutional barriers are considered to have counteracted the assumption of a sustainable behaviour. Therefore, further research on stakeholder attitudes may promote the implementation of such behaviour. The aim of the work is to present suggestions for improvement on how the climate impact can be reduced in soil remediation projects. Method: The study was performed as a qualitative survey. Empirical data was obtained in verbal form through the methods literature review, document analysis and interview. From an available group, six respondents were selected who represent significant stakeholders in soil remediation projects. Stakeholders were private and public clients, contractors, consultants and regulators. Analysed documents were reports from the Swedish Environmental Protection Agency that is about the post-treatment of contaminated areas in Sweden. Findings: The study indicates that biological soil remediation methods have a lower impact on the climate than dig and dump. Furthermore, it appeared that the main factors in choosing a soil remediation method was type of contamination, time for remediation and when contamination is detected in projects. According to this background, biological methods are less applied than dig and dump. However, the study presents suggestions for improvements of how biological alternatives can be encouraged, for instance are more reference objects needed where biological soil remediation methods have been applied. Implications: One conclusion from the study is that existing regulations should be changed to make landfill more difficult and to facilitate re-use of polluted masses, and the fees for landfill should be increased. In addition, more reference objects need to be generated in Sweden that validate that biological soil remediation methods achieve acceptable levels of pollution. Furthermore, stakeholders in soil remediation projects should cooperate more, even across national borders, and together venture to try biological soil remediation methods. Limitations: The result is only valid for biological soil remediation methods and dig and dump for organic pollutants in soil. The study includes few respondents from av geographic limited available group, which means that the result cannot be generalized with certainty. Therefore, the study should be regarded as exploratory and the results thereafter. / Syfte: I Sverige återfinns områden som är förorenade och i behov av efterbehandling, dock har marksaneringsprocesser en negativ sekundär påverkan på klimatet. Det finns olika markasaneringsmetoder att tillämpa varav schakt och deponering är den mest frekvent använda. Emellertid innebär metoden höga utsläpp av koldioxid. Tillämpning av alternativa åtgärder, såsom biologiska marksaneringsmetoder, kan bidra till lägre koldioxidutsläpp. Vid val av saneringsmetod integreras hållbarhet alltmer, men de flesta besluten baseras ändå på andra faktorer. Psykologiska, sociala och institutionella hinder anses ha motverkat antagandet av ett hållbart beteende. Därför kan fortsatt forskning om intressenters inställning främja implementering av ett sådant beteende. Målet med arbetet är att presentera förbättringsförslag på hur klimatpåverkan kan minskas vid marksaneringsprojekt. Metod: Arbetet utfördes i form av en kvalitativ kartläggning. Insamling av empiri skedde i verbal form genom datainsamlingsmetoderna litteraturstudie, dokumentanalys och intervju. Ur en tillgänglig grupp valdes sex stycken respondenter som representerar betydande intressenter vid marksaneringsprojekt. Intressenterna var privat- och offentlig beställare, entreprenör, konsult samt tillsynsmyndigheter. Dokument som analyserades var rapporter från Naturvårdsverket som behandlar efterbehandling av förorenade områden i Sverige.  Resultat: Studien indikerar att biologiska marksaneringsmetoder har lägre klimat-påverkan än schakt och deponering. Vidare framgick att de främsta faktorerna vid val av marksaneringsmetod var typ av förorening, saneringstid och när föroreningen upptäcks i projekt. Med denna bakgrund tillämpas biologiska åtgärder mer sällan än schakt och deponering. Emellertid presenterar studien förbättringsförslag till hur tillämpning av biologiska alternativ kan främjas, bland annat behövs fler referensobjekt där biologiska marksaneringsmetoder tillämpats.  Konsekvenser: En slutsats från studien är att gällande regelverk bör förändras för att försvåra deponering och underlätta återanvändning av förorenade massor samt bör avgifterna för deponering höjas. Dessutom behöver fler referensobjekt genereras i Sverige som påvisar att biologiska marksaneringsmetoder uppnår godkända föroreningshalter. Vidare bör intressenterna vid marksaneringsprojekt samarbeta mer, även över nationella gränser, för att tillsammans våga tillämpa biologiska mark-saneringsmetoder.  Begränsningar: Resultatet är endast giltigt för biologiska marksaneringsmetoder samt schakt och deponering av organiska föroreningar i mark. Studien inkluderar få respondenter ur en geografiskt begränsad tillgänglig grupp, vilket gör att resultatet inte med säkerhet kan generaliseras. Därmed bör studien betraktas som utforskande och resultatet därefter.

Attityder och hinder för användning av kryptovalutor som betalningsmedel : En kvalitativ studie om faktorer som påverkar användningen av kryptovalutor / Attitudes and barriers to the use of cryptocurrencies as means of payment : A qualitative study on factors affecting the use of cryptocurrencies

Yara, Dylan, Hanna, Hélen January 2023 (has links)
Under de senaste åren har kryptovalutor som Bitcoin blivit alltmer populära och genererat stor uppmärksamhet inom finansiella och tekniska kretsar. Trots den ökande populariteten och intresset för kryptovalutor som investeringsobjekt och spekulativt instrument, är deras användning som betalningsmedel fortfarande begränsad. Det finns flera faktorer som kan påverka användares acceptans av kryptovalutor för transaktioner, inklusive osäkerhet kring säkerhet och integritet, brist på reglering och stabilitet, och begränsad acceptans hos handlare och serviceleverantörer. Studiens syfte avser att undersöka varför kryptovaluta som betalningsmedel inte fått genomslag på den svenska marknaden, och de attityder som ligger till grund för detta. Till val av metod har triangulering använts för att samla in data genom vetenskapliga artiklar, enkäter och intervjuer. Fokus har legat på att få en förståelse för användare av kryptovalutor. Genom att engagera användarna direkt har vi haft möjlighet att lyssna på deras åsikter, erfarenheter och attityder på en djupare nivå. Genom att undersöka användares uppfattningar om att använda kryptovalutor som betalningsmedel, kan vi belysa viktiga insikter som kan forma framtida utveckling och acceptans av kryptovalutor. Samtliga data analyseras med hjälp av innehållsanalys. Resultatet som framställdes var att informationen kring kryptovalutor framstår i sin helhet som bristfällig. Genom att nå ökad förståelse kan man öka intresset och användningen av teknologin. Genom att undersöka och analysera olika aspekter av kryptovalutors acceptans och användning som betalningsmedel har vi identifierat flera viktiga faktorer som påverkar människors beslut att använda denna teknologi. Bland de främsta faktorerna är kunskap om kryptovalutor, uppfattningar om säkerhet och integritet, acceptans hos företag och serviceleverantörer, samt fördelarna med snabba och enkla transaktioner. Samtidigt har vi noterat att bristande kunskap och osäkerhet kring kryptovalutor kan vara en bromsande faktor för deras acceptans. För att öka användningen av kryptovalutor som betalningsmedel bör det finnas en kombination av utbildning, reglering, acceptans och incitament för användare. Detta kommer att underlätta för människor att fatta informerade beslut om sina ekonomiska transaktioner och främja en hållbar och säker användning av kryptovalutor. / In recent years, cryptocurrencies such as Bitcoin have become increasingly popular and generated a lot of attention in financial and technology circles. Despite the increasing popularity and interest in cryptocurrencies as an investment and speculative instrument, their use as a means of payment is still limited. There are several factors that can affect user acceptance of cryptocurrencies for transactions, including uncertainty about security and privacy, lack of regulation and stability, and limited acceptance by merchants and service providers. The purpose of the study is to investigate why cryptocurrencies haven’t break through as a payment method on the Swedish market, and what attitudes that contributes to this. We have used triangulation as a method to collect data through scientific articles, surveys, and interviews. The focus has been on gaining an understanding of cryptocurrency users. By engaging the users directly, we have had the opportunity to listen to their opinions, experiences, and attitudes on a deeper level. By examining users' perceptions of using cryptocurrencies as a means of payment, we can emphasize important insights that can shape the future development and acceptance of cryptocurrencies. All data is analyzed using content analysis. The information about cryptocurrencies appears to be deficient. By achieving increased understanding, interest and use of the technology can be increased. By researching and analyzing various aspects of cryptocurrency acceptance and use as a means of payment, we have identified several important factors that influence people's decisions to use this technology. Among the main factors are knowledge of cryptocurrencies, perceptions of security and privacy, acceptance by businesses and service providers, and the benefits of fast and easy transactions. At the same time, we have noted that lack of knowledge and uncertainty surrounding cryptocurrencies can be a slowing factor for their acceptance. To increase the use of cryptocurrencies as a means of payment, there should be a combination of education, regulation, acceptance, and incentives for users. This will facilitate people to make informed decisions about their financial transactions and promote the sustainable and safe use of cryptocurrencies.

政府採購政策變遷之研究– 以臺北市政府聯合採購發包中心設置為例 / A Study on the Policy Change of Government Procurement – Case Study of Contract Centers Mechanism of Taipei City Government

呂蕙蕙, Lu, Hui Hui Unknown Date (has links)
有關政府採購研究,現行大部分關注在法律層面、制度層面。本研究擬從政策變遷與宏觀角度切入,就發包中心設置過程因果關係,發現決策者信念、政策中間人、聯盟運作等對政策影響。本文擬透過Sabatier & Jenkins-Smith 所建構政策倡議聯盟架構(Policy Advocacy Coalition Framework,[PACF ]),從不同面相研究觀察,以宏觀之政策面,研究分析市府發包中心重新設置之動態過程。 本研究採文獻分析法、深入訪談及焦點團體訪談法,分析探討1995至2015年臺北市政府聯合採購發包中心設置之政策變遷過程。藉由分析架構內外在系統的影響因素,探討執政輪替與決策者的信念是否為影響政策變遷主要因素。經研究發現:第一,市府倡議聯盟間(發包中心與洽辦單位、集中採購與分散採購)透過政策導向的學習,跨越聯盟達成共識。第二,避免陳水扁時代採購案件延宕,改以折衷版集中採購。第三,柯文哲市長主張集中採購,設置發包中心政策是其競選政策白皮書。第四,市府發包中心設置政策變遷主因,決策者信念與執政輪替。 / With regard to government procurement research, most of them focus on the legal and institutional aspects. This study intends to proceed from the perspective of policy changes and macroeconomics. It will investigate the cause-and-effect relationship of the setup process of the contract issuing center, and discover the impact of decision makers' beliefs, policy middlemen, and alliance operations on the policy. Using the policy advocacy coalition framework (PACF) constructed by Sabatier & Jenkins-Smith , we observe and analyze the dynamic process of the resetting of the city's outsourcing centers. This study used document analysis, in-depth interviews, and focus group interviews to analyze and explore the process of policy changes at the Joint Purchasing and Contracting Center of the Taipei City Government from 1995 to 2015. By analyzing the influencing factors of the internal and external systems of the architecture, it is discussed whether the alternation of governance rotation and decision makers' beliefs are the main factors affecting policy changes. The study found that: First, the city’s initiative among the alliances (contracting centers and contact agencies, centralized procurement and decentralized procurement) through policy-oriented learning, reached consensus across the alliance. Second, to avoid delays in Chen Shui-bian’s era of procurement cases , it used eclectic centralized procurement. Thirdly, Mayor Ko Wen-je advocated centralized procurement and set up a contract center policy as a white paper on his election policy. Fourth, the main reasons for the policy changes in the city's outsourcing centers are decision makers' beliefs and governance rotation.
