Abstract:
Organizational information technology (IT) needs are served through increasingly complex configurations of people, technologies, organizations, and shared information. Ideally, an organizational IT service is valuable for both the providers and users of systems and solutions. However, mutually beneficial outcomes may be difficult to achieve within the configurations through which IT services are delivered. We suggest that analyzing stakeholder interplay in IT service processes helps us to understand how information systems (IS) organizations can be leveraged to co-create business value. Through a qualitative empirical inquiry, we explore IT service realization in two case organizations. Through our analysis we find that value creation builds on orchestrated social action among the different stakeholder groups involved. Joint value creation in IT service processes hence calls for specific network leadership and resource integration capabilities from the IS organization. The paper enriches the current understanding of business value creation in IT services by infusing the service logic with traditional IT management perspectives. The findings highlight that the extent to which the IS organization can learn to facilitate the interaction between the essential actors in an ‘IT service system’ and leverage user-perceived value throughout the service process will ultimately determine its success or failure.

Abstract:
Coordination is one of the essential problems in multi-agent systems. Typically multi-agent reinforcement learning (MARL) methods treat agents equally and the goal is to solve the Markov game to an arbitrary Nash equilibrium (NE) when multiple equilibra exist, thus lacking a solution for NE selection. In this paper, we treat agents unequally and consider Stackelberg equilibrium as a potentially better convergence point than Nash equilibrium in terms of Pareto superiority, especially in cooperative environments. Under Markov games, we formally define the bi-level reinforcement learning problem in finding Stackelberg equilibrium. We propose a novel bi-level actor-critic learning method that allows agents to have different knowledge base (thus intelligent), while their actions still can be executed simultaneously and distributedly. The convergence proof is given, while the resulting learning algorithm is tested against the state of the arts. We found that the proposed bi-level actor-critic algorithm successfully converged to the Stackelberg equilibria in matrix games and find a asymmetric solution in a highway merge environment.

Abstract:
The loss of ecosystem services through land degradation continues to be a significant concern for policymakers and land users around the world. Facilitating collective action among various actors is regarded as imperative in halting land degradation. Despite extensive research on collective action, there have been few studies that continuously map social ties and detect network evolution as a way of enabling longitudinal analysis of transformative spaces. This paper seeks to examine the changing dynamics of multi-actor and multi-level actor ties over a period of two years in Machubeni, South Africa. To do this, we used social network analysis to detect continuities and/or discontinuities of multi-actor and multi-level actor ties over time. Overall, edge density, clustering coefficient, and reciprocity scores steadily increased over the two years despite a decline in the number of active organisations within the network. Our results demonstrate that the proportion of strong ties gradually increased over time across three governance networks. However, multi-level linkages between the local municipality and the local organisations remained weak due to a lack of trust and collaborative fatigue. While the transformative space has succeeded in enhancing collaboration and knowledge sharing between local organisations and researchers, further long-term engagement with government agencies might be necessary for promoting institutional transformations and policy outcomes, and building network resilience in complex polycentric governance systems.

Abstract:
2010/2011
The study of the models and methods to apply to multi-actor systems is a widely discussed research topic in the related scientific literature. The multi-actor systems are defined as systems that are characterized by the presence of several autonomous elements, of different decision makers and of complex rules that allow the communication, the coordination and the connection of the components of such systems. Commonly, the study of Multi-Actor System, MAS, recalls the well-known issues concerning the multi-agent systems. The research topic related to the multi-agent system firstly started to appear in scientific literature in 1980s, mainly in relation to the computer science and artificial intelligence. In this dissertation, in particular, the study of the multi-agent systems, and specifically of the multi-actor systems, is taken into account merely in relation to the distinctive features of complexity that characterize such systems and not to the issues concerning the agent-oriented software engineering. Therefore, the research results presented in this thesis are focused on the development and on the realization of innovative models and methodologies to face the management and the decision making mechanisms applied to complex multi-actor systems. This dissertation especially focuses on two different examples of multi-actor systems in two very diverse perspectives. The former deals with the research problem related to intermodal transportation networks, while the latter with the so called consensus problem in distributed networks of agents. Concerning the research problem related to the intermodal logistic systems, the research activity addresses the management of their more and more increasing complexity by the applications of the modern Information and Communication Technologies (ICT) tools that are key solutions to achieve the efficiency and to enhance logistics competitiveness. The related scientific literature still seems lacking in addressing with adequate attention the impact of these new techniques on the management of these complex systems and, moreover, there is an apparent lack of a systematic and general methodology to describe in detail the multiplicity of elements that can influence the dynamics and the corresponding information and decision making structure of intermodal transportation systems. The innovative results presented in this dissertation are focused on the development of an Integrated System, IS, devoted to manage intermodal transportation networks at the tactical as well as operational decision level to be used by decision makers both in off-line planning and real time management. To specify the Integrated System, a reference model is developed relying on a top-down metamodeling procedure. These innovative research results are a contribution to bridge the gap and to propose not only a systematic modeling approach devoted to describe a generic multi-actor logistic system, but also a management technique based on a closed loop strategy. The second example of application is focused on a topic that is widely discussed in scientific literature related to the study of the multi-actor collective behaviors in a distributed network. The interaction protocols that allow the agents to reach the convergence to a common value is called consensus or agreement problem. This research problem is particularly studied in the context of cooperative control of multi-agent systems because the agents are autonomous, independent and have to interact in a distributed network. The presented research results address the investigation of new and fast alignment protocols that enhance the performances of the standard iteration protocols for particular topologies of digraphs on the basis of a triangular splitting of the standard iteration matrix. The examined examples, the models and the methodologies applied to analyze them, are very different in the two cases and this testifies the large extent of research problems related to the multi-actor systems.
L’analisi di modelli e metodi da sviluppare e da applicare nel contesto dei sistemi multi-attoriali costituisce un tema molto variegato e discusso nella letteratura scientifica internazionale. I sistemi multi-attoriali sono sistemi che si contraddistinguono per la presenza di molti elementi autonomi diversi tra loro, di molteplici decisori e di complesse regole che determinano la comunicazione, il coordinamento e la connessione all'interno di tali sistemi. Frequentemente, facendo riferimento a sistemi multi-attoriali, Multi-Actor Systems, si richiama il tema molto attuale dei sistemi multi agente, Multi-Agent Systems. Diffusisi a partire dal 1980, i sistemi multi agente sono spesso studiati in relazione alle metodologie di sviluppo dell'ingegneria del software. Nel presente lavoro di tesi, il tema dei sistemi multi-agente, ed in particolare di quelli multi-attoriali, non viene analizzato in questo contesto, ma in relazione alle tecniche decisionali da adottare per gestire sistemi caratterizzati da un alto livello di complessità. In tale ambito, i risultati presentati all'interno di questa dissertazione sono focalizzati sullo sviluppo e sulla realizzazione di nuovi metodi e di nuove metodologie, in grado di affrontare la gestione della complessità dei sistemi multi-attoriali. Vengono in particolare esaminate due diverse problematiche, in due contesti completamente diversi e con tecniche differenti, a testimoniare le vaste applicazioni che riguardano i sistemi multi-attoriali. I problemi analizzati sono incentrati, in primo luogo, su un'applicazione inerente la gestione di sistemi logistici intermodali ed, in secondo luogo, sullo studio delle regole o protocolli di interazione in una rete distribuita di agenti autonomi. Per quanto riguarda l'aspetto legato ai sistemi intermodali di trasporto, un tema molto discusso nella letteratura scientifica recente, l'analisi si focalizza sulla gestione della loro sempre crescente complessità, tramite l'utilizzo di sistemi dell'Information and Communication Technology, ICT. Questi strumenti richiedono metodi e modelli che sono innovativi rispetto a quanto è presente nella letteratura scientifica, all'interno della quale è stata riscontrata la mancanza di un approccio sistematico e sufficientemente ad alto livello per la realizzazione di una metodologia in grado di descrivere allo stesso tempo sia la molteplicità di elementi che influenzano le dinamiche e le informazioni, sia le strutture decisionali dei sistemi intermodali. L'innovazione dei risultati presentati in questa tesi si focalizza proprio sull'esigenza di proporre un sistema integrato, Integrated System (IS), basato su un metamodello delle reti intermodali di trasporto, che fornisca un valido supporto ai decisori sia a livello tattico che operativo. Il secondo aspetto affrontato in questa tesi riguarda un altro argomento di largo ed attuale interesse nella letteratura scientifica, che viene comunemente chiamato problema del consenso. Questo problema affronta lo studio di come diversi agenti autonomi collocati su una rete distribuita siano in grado di comunicare e di accordarsi su un valore comune, senza la presenza di un decisore centrale. A questo scopo ci sono degli algoritmi che specificano le regole o protocolli di interazione tra i diversi agenti. In tale contesto, i risultati proposti si focalizzano su alcune problematiche rappresentate dal protocollo classico del consenso e soprattutto sulla sua scarsa efficienza in particolari conformazioni delle reti di agenti. Il lavoro di tesi propone, quindi, un approccio di suddivisione, splitting, della matrice standard di iterazione, di tipo triangolare, che presenta notevoli vantaggi in termini di performance rispetto all'algoritmo classico. Lo studio di problemi multi-attoriali, pertanto, richiede lo sviluppo di innovative metodologie decisionali e di nuovi metodi di gestione delle comunicazioni, per rispondere al livello sempre crescente di complessità, offrendo in questo modo alcuni spunti molto interessanti per la ricerca.

Abstract:
Community benefit schemes in the context of wind power are increasingly provisioned by developers as a means of generating local socio-economic and environmental value, fostering social relations and strengthening acceptance. Determining an appropriate and effective benefit scheme can prove challenging, given the variation of exposed stakeholders, diversity in schemes and the lack of decision making guidance. A multi-criteria decision aid framework for identifying the most appropriate scheme(s) for a hypothetical wind power project is developed. The framework is based on AHP and PROMETHEE II decision support tool, where six (6) alternative schemes are assessed using the preferences of five (5) stakeholders and their relevant criteria. The framework was applied to a fictitious development on the island of Gotland. Results from the applied example indicate that the most locally suited outcome was the ownership based models. It is anticipated that the methodological framework can help identify the scheme(s) that respond to the needs and preferences of the locality. Moreover, a decision making platform of this nature can provide practical support to developers, communities and local authorities, and contribute to a more effective and efficient development and negotiation process surrounding community benefit schemes.

Abstract:
This paper explores the value propositions that exist within ecosystems comprised of organizational and individual actors. The concept of value in general and how value is cocreated in multi-actor networks is explored by using service-dominant logic. The ecosystem is further framed by the intrinsic traits of digital technology as portrayed in The Layered Architecture of Digital Technology. Together, both of these framing conventions create what the paper refers to as a digital service ecosystem. In order to understand the important characteristics of a digital service ecosystem this paper analyzes a case study involving several actors participating in an ecosystem project in northern Sweden. This paper identifies six overarching themes that serve as the basis for three value propositions. A model is introduced as a way to simplify the understanding of each value proposition and how they interact with one another.

Abstract:
With the introduction of RIS and PACS technologies in clinical radiology, the field has become increasingly technology dependent. The quality assurance in radiology have however yet to catch on. With many quality assurance programs mainly focusing on the clinical side of radiology whilst little attention is paid to the technical aspects. This thesis serves to change that, by investigating quality assurance of radiology equipment in the workflow of hospital physicists and biomedical engineers at Södersjukhuset emergency hospital. To improve said workflows, process modelling and multi-actor system analysis was utilized in combination with the on-site inventory system Medusa. In order to model the workflows, the process modelling technique flowchart was used. To add additional information into the flowcharts, multi-actor system analysis was employed. This was done for the workflow of both scheduled and unscheduled maintenance of radiology equipment. Initially resulting in a pair of pre-study models which modelled the after the existing workflows. From said pair of pre-study models, both redundancies and main objectives for improvement were deduced. This in combination with an extensive semistructured literature review, led to a list of requirements. Two pairs of improved models were then created with the list of requirements in mind. All the models were then evaluated, including the pair of pre-study models, in workshops held with hospital physicists, biomedical engineers and respective leadership staff. These workshops contained both an open discussion and a questionnaire, asking the participants to rate the alignment of the models with the different requirements in the list. Based on the results from the workshops, one of the proposed pairs of improved models were then chosen as the final solution of an improved workflow. A workflow in which redundancies were reduced, traceability capabilities added in form of digital storage, and alignment with legislative demands from SSM assured. A step in the digitalization of Södersjukhuset. Utilizing digital technology to improve quality assurance in the workflow of radiology equipment.
I samband med introduktionen av RIS och PACS teknologi i klinisk radiologi, så har fältet blivit mer teknikdrivet. Kvalitetledning av radiologisk utrustning har däremot inte förändrats. Då de flesta kvalitetslednings program har primärt fokus på den kliniska sidan av radiologi och förbiser de tekniska aspekterna. Detta examensarbete försöker bemöta detta, genom att utreda kvalitetsledningen av radiologisk utrustning hos arbetsflödena av sjukhusfysiker och medicintekniska ingenjörer på Södersjukhuset. För att förbättra arbetsflödena, så användes processmodellering och analys av multi-aktörsystem i kombination med det lokala inventariesystemet Medusa. För att skapa en modell av arbetsflödet så användes processmodelleringstekniken flowchart. För att lägga till ytterligare information i flödena så utfördes en multi-aktörsystem analys. Detta utfördes för både förebyggande- och avhjälpande underhåll av radiologisk utrustning. Vilket resulterade i ett par av förstudiemodeller som modellerade det nuvarande arbetsflödet. Baserat på detta par av förstudiemodeller, så kunde både överflödigheter och huvudsakliga förbättringsmål härledas. Detta i kombination med en semistrukturerad litteraturundersökning, ledde till en lista med krav på modellerna. Sedan så skapades två par av modeller som förslag till förbättrat arbetsflöde, baserat på listan med krav. För att utvärdera alla modeller, inklusive förstudiemodellerna, så hölls workshops med sjukhusfysiker, medicintekniska ingenjörer och respektive chefspersonal. Dessa workshops innehöll både en öppen diskussion och ett formulär, som bad deltagarna att utvärdera de olika paren av modeller gentemot de olika kraven som hade formulerats i listan. Baserat på resultaten från dessa workshops, så valdes en av de två förslagna paren av modeller för förbättrat arbetsflöde, som en slutgiltig lösning. Ett arbetsflöde där överflödigheter har motarbetats, spårbarhet förbättrats med hjälp av digital lagring, och sammanstämning med regulatoriska krav från SSM har säkerställts. Ett steg i digitaliseringen av Södersjukhuset, genom att utnyttja digital teknik för att förbättra kvalitetledningen av radiologisk utrustning.

Abstract:
L’Intelligence Ambiamte (AmI) est un domaine de recherche investigant les techniques d’intelligence artificielle pour créer des environnements réactifs. Les réseaux de capteurs et effecteurs sans-fils sont les supports de communication entre les appareils ménagers, les services installés et les interfaces homme-machine. Cette thèse s’intéresse à la conception d’Environements Réactifs avec des propriétés autonomiques i.e. des systèmes qui ont la capacité de se gérer eux-même. De tels environements sont ouverts, à grande échelle, dynamique et hétérogène, ce qui induit certains problèmes pour leur gestion par des systèmes monolithiques. L’approche proposée est bio-inspirée en considérant chacune des plate-formes comme une cellule indépendente formant un organisme intelligent distribué. Chaque cellule est programmée par un processus ADN-RNA décrit par des règles réactives décrivant leur comportement interne et externe. Ces règles sont modelées par des agents mobiles ayant des capacités d’auto-réécriture et offrant ainsi des possibilités de reprogrammation dynamique. Le framework EMMA est composé d’un middleware modulaire avec une architecture orientée ressource basée sur la technologie 6LoWPAN et d’une architecture MAPE-K pour concevoir des AmI à plusieurs échelles. Les différentes relations entre les problèmes techniques et les besoins théoriques sont discutées dans cette thèse depuis les plate-formes, le réseau, le middleware, les agents mobiles, le déploiement des applications jusqu’au système intelligent. Deux algorithmes pour AmI sont proposés : un modèle de contrôleur neuronal artificiel pour le contrôle automatique des appareils ménagers avec des processus d’apprentissage ainsi qu’une procédure de vote distribuée pour synchroniser les décisions de plusieurs composants systèmes
AThe Ambient Intelligence (AmI) is a research area investigating AI techniques to create Responsive Environments (RE). Wireless Sensor and Actor Network (WSAN) are the supports for communications between the appliances, the deployed services and Human Computer Interface (HCI). This thesis focuses on the design of RE with autonomic properties i.e. system that have the ability to manage themselves. Such environments are open, large scale, dynamic and heterogeneous which induce some difficulties in their management by monolithic system. The bio-inspired proposal considers all devices like independent cells forming an intelligent distributed organism. Each cell is programmed by a DNA-RNA process composed of reactive rules describing its internal and external behaviour. These rules are modelled by reactive agents with self-rewriting features offering dynamic reprogramming abilities. The EMMA framework is composed of a modular Resource Oriented Architecture (ROA) Middleware based on IPv6 LoW Power Wireless Area Networks (6LoWPAN) technology and a MAPE-K architecture to design multi-scale AmI. The different relations between technical issues and theoretical requirements are discussed through the platforms, the network, the middleware, the mobile agents, the application deployment to the intelligent system. Two algorithms for AmI are proposed: an Artificial Neural Controller (ANC) model for automatic control of appliances with learning processes and a distributed Voting Procedures (VP) to synchronize the decisions of several system components over the WSAN

Abstract:
Le travail de recherche présenté dans cette thèse s’inscrit dans la continuité des travaux de l’aide à la décision multi-critère de groupe (décideurs), particulièrement dans le champ de sélection de la localisation des centres de distribution. Dans un environnement certain, si la décision de sélection de la localisation des centres de distribution a donné lieu à plusieurs travaux de recherche, elle n’a jamais été l’objet, à notre connaissance, d’une décision prise par plusieurs décideurs. À cet égard, le premier objectif de cette thèse est de proposer une méthode d’aide à la décision multi-attribut et multi-acteur (MAADM) pour résoudre le problème posé. Pour se faire, nous avons adapté et étendu la méthode ELECTRE I. Dans un environnement incertain, au vu de l’incertitude inhérente et l’imprécision du processus décisionnel humain ainsi que les comportements futurs du marché et des entreprises, le deuxième objectif de cette thèse est de développer une méthode floue d’aide à la décision multi-attribut et multi-acteur (FMAADM) pour traiter le problème en question. Pour cela, nous avons couplé la méthode MAADM avec la théorie des ensembles flous. Pour la validation des deux contributions, nous avons conçu un système d’aide à la décision (S-DSS) pour implémenter les algorithmes de la méthode MAADM et la méthode FMAADM. Sur la base du S-DSS, deux études expérimentales ont été menées. Nous avons, aussi, appliqué une analyse de sensibilité pour vérifier la sensibilité de la solution retenue vis-à-vis aux variations de poids des critères d’évaluation. Les résultats obtenus prouvent que les deux méthodes proposées répondent à l’objectif recherché et ainsi retenues pour la sélection de la meilleure localisation dans un contexte certain/incertain de multi-attribut et multi-acteur
The research work presented in this thesis is part of the works’ continuity on multi-criteria group (decision-makers) decision-making, particularly in the field of the distribution centers’ location selection. Under certain environment, although the decision to select the location of the distribution centers has given rise in several research works, it has never been the object, to our knowledge, of a decision taken by several decision makers. In this regard, the first objective of this thesis is to develop a multi-attribute and multi-actor decision-making method (MAADM) to resolve the posed problem. For this purpose, we have adapted and extended the ELECTRE I method. Under uncertain environment, In view of the inherent uncertainty and inaccuracy of human decision-making, the future behavior of the market and companies, the second objective of this thesis is to propose a fuzzy multi-attribute and multi-actor decision-making method (FMAADM) to treat the problem in question. To this end, we have coupled the MAADM method with the fuzzy set theory. To validate the two contributions, we designed a decision support system (S-DSS) to implement the MAADM method and the FMAADM method. Based on the S-DSS, two experimental studies were conducted. We also applied a sensitivity analysis to verify the sensitivity of the solution retained vis-a-vis to weights’ variations of evaluation criteria. The obtained results prove that the MAADM method and the FMAADM method meet the desired objective and thus retained for the selection of the best location under certain/uncertain context of multi-attribute and multi-actor

Information and Communication Technologies (ICT) have been used in many areas and common activities, but although there are initiatives undertaken by government and private institutions, health informatics are still an open challenge in Brazil. Today’s scenario raises questions about difficulties related to informatics usage in health and healthcare practices, as well as, the effects of these difficulties on Brazilian society. Aiming to discuss the aforementioned questions, this thesis presents four papers about health informatics in Brazil. The first paper reviews literature about ICT in health. Therefore, based on two theoretical perspectives – (a) European studies about Health Information Systems (HIS) in Developing Countries and (b) studies on Information and Informatics in Health, in the Sanitary Reform Movement –, the paper proposes an integrated model linking analytical dimensions and contextual factors in order to understand HIS in Brazil. The second paper presents theoretical and methodological concepts from Actor-Network Theory (ANT), a research approach to investigate controversies associated with scientific discoveries and technological innovations, based on the network of actors related to such actions. The ANT theoretical approach has supported IS research since 1990 and inspired the analysis conducted in the third and fourth papers presented in this thesis. The final two papers have been written based on the case analysis from the deployment of an HIS in a public hospital in Brazil, conducted during 2010 and 2012. In order to analyze the case, the actors involved in the controversies that emerged during the deployment of the HIS were followed. The third paper focuses on the activities of system analysts and users involved in the HIS deployment. The changes observed over the course of the system deployment reveal that success has not been achieved by the strict and technical execution of the planned tasks. Rather, the success has been constructed collectively through negotiation among actors and the introduction of ‘devices of interessement’ during the project. The fourth paper, based on the Information Infrastructures concept, discusses how the CATMAT system has been merged with the E-Hosp. The analysis reveals how the installed base of CATMAT has been a relevant condition leading to is selection during the E-Hosp deployment. Moreover, it describes negotiations and heterogeneous operations that occurred during the integration of CATMAT into E-Hosp. Thus, this thesis argues that HIS deployment is an effort of collective construction, involving system analysts, health professionals, politicians and technical artifacts. In addition, it makes clear how HIS inscribes definitions and agreements, influencing actors’ preferences in health and healthcare.
As tecnologias da informação e comunicação (TIC) estão presentes nas mais diversas áreas e atividades cotidianas, mas, em que pesem as ações de governos e instituições privadas, a informatização da saúde ainda é um desafio em aberto no Brasil. A situação atual leva a um questionamento sobre as dificuldades associadas à informatização das práticas em saúde, assim como, quais efeitos tais dificuldades têm causado à sociedade Brasileira. Com objetivo de discutir as questões acima citadas, esta tese apresenta quatro artigos sobre processo de informação da saúde no Brasil. O primeiro artigo revisa a literatura sobre TIC em saúde e baseado em duas perspectivas teóricas – estudos Europeus acerca dos Sistemas de Informação em Saúde (SIS) nos Países em Desenvolvimento e estudos sobre Informação e Informática em Saúde, no âmbito do Movimento da Reforma Sanitária –, formula um modelo integrado que combina dimensões de análise e fatores contextuais para a compreensão dos SIS no Brasil. Já o segundo artigo apresenta os conceitos e teóricos e metodológicos da Teoria Ator-Rede (ANT), uma abordagem para o estudo de controvérsias associadas às descobertas científicas e inovações tecnológicas, por meio das redes de atores envolvidos em tais ações. Tal abordagem tem embasado estudos de SI desde 1990 e inspirou as análises dois artigos empíricos desta tese. Os dois últimos artigos foram redigidos a partir da análise da implantação de um SIS em um hospital público no Brasil ocorrida entre os anos de 2010 e 2012. Para a análise do caso, seguiram-se os atores envolvidos nas controvérsias que surgiram durante a implantação do SIS. O terceiro artigo se debruçou sobre as atividades dos analistas de sistema e usuários envolvidos na implantação do SIS. As mudanças observadas durante a implantação do sistema revelam que o sucesso do SIS não foi alcançado pela estrita e técnica execução das atividades incialmente planejadas. Pelo contrário, o sucesso foi construído coletivamente, por meio da negociação entre os atores e de dispositivos de interessamento introduzidos durante o projeto. O quarto artigo, baseado no conceito das Infraestruturas de Informação, discutiu como o sistema CATMAT foi incorporado ao E-Hosp. A análise revelou como a base instalada do CATMAT foi uma condição relevante para a sua escolha durante a implantação do E-Hosp. Além disso, descrevem-se negociações e operações heterogêneas que aconteceram durante a incorporação do CATMAT no sistema E-Hosp. Assim, esta tese argumenta que a implantação de um SIS é um empreendimento de construção coletiva, envolvendo analistas de sistema, profissionais de saúde, políticos e artefatos técnicos. Ademais, evidenciou-se como os SIS inscrevem definições e acordos, influenciando as preferências dos atores na área de saúde.

Abstract:
‘CSR and new governance’ is concerned with the institutionalization of corporate social responsibility (CSR) within systems of societal governance. CSR emerges as a means of governing business and of bringing business to wider governance agendas—referred to as ‘new governance’. CSR features in a range of new governance systems, particularly in the standards and partnerships that institutionalize responsible business behaviour. The ways in which business defines and manages CSR, through new associations and individual companies, are reviewed, along with multi-actor organizations in which CSR also gets regulated and organized, including UN initiatives and a group of new CSR standards; the Extractive Industries Transparency Initiative; the Ethical Trade Initiative; and a group of resource-specific stewardship councils.

Abstract:
The European Union (EU) is a regional cooperation regime with a specific and still fluid governance structure. It constitutes the world’s largest and institutionally most deeply integrated system of international relations with supranational features. As a consequence, the literature on the EU often emphasizes informality, multilevel aspects, and its “network governance” character. Network analysis is therefore a promising perspective for the systematic investigation of complex networks of formalized actor relations as well as of informal and implicit political structures and processes in the EU. Applied network analysis is meanwhile used for the investigation of multi-level policy preparation, of collective decision-making in the political system in the EU, and of the implementation process of EU policies in the Member States.
