Ramchurn, Sarvapali Dyanand. "Multi-agent negotiation using trust and persuasion". Thesis, University of Southampton, 2004. https://eprints.soton.ac.uk/260200/.
Testo completoAbstract (sommario):
In this thesis, we propose a panoply of tools and techniques to manage inter-agent dependencies in open, distributed multi-agent systems that have significant degrees of uncertainty. In particular, we focus on situations in which agents are involved in repeated interactions where they need to negotiate to resolve conflicts that may arise between them. To this end, we endow agents with decision making models that exploit the notion of trust and use persuasive techniques during the negotiation process to reduce the level of uncertainty and achieve better deals in the long run. Firstly, we develop and evaluate a new trust model (called CREDIT) that allows agents to measure the degree of trust they should place in their opponents. This model reduces the uncertainty that agents have about their opponents' reliability. Thus, over repeated interactions, CREDIT enables agents to model their opponents' reliability using probabilistic techniques and a fuzzy reasoning mechanism that allows the combination of measures based on reputation (indirect interactions) and confidence (direct interactions). In so doing, CREDIT takes a wider range of behaviour-influencing factors into account than existing models, including the norms of the agents and the institution within which transactions occur. We then explore a novel application of trust models by showing how the measures developed in CREDIT ca be applied negotiations in multiple encounters. Specifically we show that agents that use CREDIT are able to avoid unreliable agents, both during the selection of interaction partners and during the negotiation process itself by using trust to adjust their negotiation stance. Also, we empirically show that agents are able to reach good deals with agents that are unreliable to some degree (rather than completely unreliable) and with those that try to strategically exploit their opponent. Secondly, having applied CREDIT to negotiations, we further extend the application of trust to reduce uncertainty about the reliability of agents in mechanism design (where the honesty of agents is elicited by the protocol). Thus, we develop \acf{tbmd} that allows agents using a trust model (such as CREDIT) to reach efficient agreements that choose the most reliable agents in the long run. In particular, we show that our mechanism enforces truth-telling from the agents (i.e. it is incentive compatible), both about their perceived reliability of their opponent and their valuations for the goods to be traded. In proving the latter properties, our trust-based mechanism is shown to be the first reputation mechanism that implements individual rationality, incentive compatibility, and efficiency. Our trust-based mechanism is also empirically evaluated and shown to be better than other comparable models in reaching the outcome that maximises all the negotiating agents' utilities and in choosing the most reliable agents in the long run. Thirdly, having explored ways to reduce uncertainties about reliability and honesty, we use persuasive negotiation techniques to tackle issues associated with uncertainties that agents have about the preferences and the space of possible agreements. To this end, we propose a novel protocol and reasoning mechanism that agents can use to generate and evaluate persuasive elements, such as promises of future rewards, to support the offers they make during negotiation. These persuasive elements aim to make offers more attractive over multiple encounters given the absence of information about an opponent's discount factors or exact payoffs. Specifically, we empirically demonstrate that agents are able to achieve a larger number of agreements and a higher expected utility over repeated encounters when they are given the capability to give or ask for rewards. Moreover, we develop a novel strategy using this protocol and show that it outperforms existing state of the art heuristic negotiation models. Finally, the applicability of persuasive negotiation and CREDIT is exemplified through a practical implementation in a pervasive computing environment. In this context, the negotiation mechanism is implemented in an instant messaging platform (JABBER) and used to resolve conflicts between group and individual preferences that arise in a meeting room scenario. In particular, we show how persuasive negotiation and trust permit a flexible management of interruptions by allowing intrusions to happen at appropriate times during the meeting while still managing to satisfy the preferences of all parties present.

Testo completoAbstract (sommario):
Service-oriented architectures (SOA), and in particular Web services, have quickly become a popular technology to connect applications both within and across enterprise boundaries. However, as services are increasingly used to implement critical functionality, security has become an important concern impeding the widespread adoption of SOA. Trust negotiation is an approach to access control that may be applied in scenarios where service requesters are often unknown in advance, such as for services available via the public Internet. Rather than relying on requesters' identities, trust negotiation makes access decisions based on the level of trust established between the requester and the provider in a negotiation, during which the parties exchange credentials, which are signed assertions that describe some attributes of the owner. However, managing the evolution of trust negotiation policies is a difficult problem that has not been sufficiently addressed to date. Access control policies have a lifecycle, and they are revised based on applicable business policies. Additionally, because a trust relationship established in a trust negotiation may be long lasting, their evolution must also be managed. Simply allowing a negotiation to continue according to an old policy may be undesirable, especially if new important constraints have been added. In this thesis, we introduce a model-driven trust negotiation framework for service-oriented applications. The framework employs a model for trust negotiation, based on state machines, that allows automated generation of the control structures necessary to enforce trust negotiation policies from the visual model of the policy. Our policy model also supports lifecycle management. We provide sets of operations to modify policies and to manage ongoing negotiations, and operators for identifying and managing impacts of changes to trust negotiation policies on ongoing trust negotiations. The framework presented in the thesis has been implemented in the Trust-Serv prototype, which leverages industry specifications such as WS-Security and WS-Trust to offer a container-centric mechanism for deploying trust negotiation that is transparent to the services being protected.

Ajayi, Oluwafemi O. "Dynamic trust negotiation for decentralised e-health collaborations". Thesis, University of Glasgow, 2009. http://theses.gla.ac.uk/848/.
Testo completoAbstract (sommario):
In the Internet-age, the geographical boundaries that have previously impinged upon inter-organisational collaborations have become decreasingly important. Of more importance for such collaborations is the notion and subsequent nature of security and trust - this is especially so in open collaborative environments like the Grid where resources can be both made available, subsequently accessed and used by remote users from a multitude of institutions with a variety of different privileges spanning across the collaboration. In this context, the ability to dynamically negotiate and subsequently enforce security policies driven by various levels of inter-organisational trust is essential. Numerous access control solutions exist today to address aspects of inter-organisational security. These include the use of centralised access control lists where all collaborating partners negotiate and agree on privileges required to access shared resources. Other solutions involve delegating aspects of access right management to trusted remote individuals in assigning privileges to their (remote) users. These solutions typically entail negotiations and delegations which are constrained by organisations, people and the static rules they impose. Such constraints often result in a lack of flexibility in what has been agreed; difficulties in reaching agreement, or once established, in subsequently maintaining these agreements. Furthermore, these solutions often reduce the autonomous capacity of collaborating organisations because of the need to satisfy collaborating partners demands. This can result in increased security risks or reducing the granularity of security policies. Underpinning this is the issue of trust. Specifically trust realisation between organisations, between individuals, and/or between entities or systems that are present in multi-domain authorities. Trust negotiation is one approach that allows and supports trust realisation. The thesis introduces a novel model called dynamic trust negotiation (DTN) that supports n-tier negotiation hops for trust realisation in multi-domain collaborative environments with specific focus on e-Health environments. DTN describes how trust pathways can be discovered and subsequently how remote security credentials can be mapped to local security credentials through trust contracts, thereby bridging the gap that makes decentralised security policies difficult to define and enforce. Furthermore, DTN shows how n-tier negotiation hops can limit the disclosure of access control policies and how semantic issues that exist with security attributes in decentralised environments can be reduced. The thesis presents the results from the application of DTN to various clinical trials and the implementation of DTN to Virtual Organisation for Trials of Epidemiological Studies (VOTES). The thesis concludes that DTN can address the issue of realising and establishing trust between systems or agents within the e-Health domain, such as the clinical trials domain.

Edvalson, Michael George. "Trust Broker: A Defense Against Identity Theft From Online Transactions". BYU ScholarsArchive, 2005. https://scholarsarchive.byu.edu/etd/348.
Testo completoAbstract (sommario):
The proliferation of online services over the years has encouraged more and more people to participate in Internet activities. Many web sites request personal and sensitive information needed to deliver the desired service. Unfortunately, it is difficult to distinguish the sites that can be trusted to protect such information from those that cannot. Many attempts to make the Internet easier to use introduce new security and privacy problems. On the other hand, most attempts at creating a safe online environment produce systems that are cryptic and hard to use. The TrustBroker system is based on a specialized online repository that safely stores user information and helps the user determine which sites can be trusted with their sensitive information. Also, the repository facilitates the transfer of the user's in- formation. The overall effect of the system is to inspire greater confidence in online participation among users who desire to protect their personal information.

Chan, Fuk-Wing Thomas. "Preserving Trust Across Multiple Sessions in Open Systems". BYU ScholarsArchive, 2004. https://scholarsarchive.byu.edu/etd/137.
Testo completoAbstract (sommario):
Trust negotiation, a new authentication paradigm, enables strangers on the Internet to establish trust through the gradual disclosure of digital credentials and access control policies. Previous research in trust negotiation does not address issues in preserving trust across multiple sessions. This thesis discusses issues in preserving trust between parties who were previously considered strangers. It also describes the design and implementation of trust preservation in TrustBuilder, a prototype trust negotiation system. Preserving trust information can reduce the frequency and cost of renegotiation. A scenario is presented that demonstrates that a server supporting trust preservation can recoup the cost of the trust preservation facility when approximately 25% of its requests are from repeat customers. The throughput and response time improve up to approximately 33% as the percentage of repeat customers grows to 100%.

Hellewell, Phillip L. "Extensible Pre-Authentication in Kerberos". BYU ScholarsArchive, 2007. https://scholarsarchive.byu.edu/etd/1395.
Testo completoAbstract (sommario):
Organizations need to provide services to a wide range of people, including strangers outside their local security domain. As the number of users grows larger, it becomes increasingly tedious to maintain and provision user accounts. It remains an open problem to create a system for provisioning outsiders that is secure, flexible, efficient, scalable, and easy to manage. Kerberos is a secure, industry-standard protocol. Currently, Kerberos operates as a closed system; all users must be specified upfront and managed on an individual basis. This paper presents EPAK (Extensible Pre-Authentication in Kerberos), a framework that enables Kerberos to operate as an open system. Implemented as a Kerberos extension, EPAK enables many authentication schemes to be loosely coupled with Kerberos, without further modification to Kerberos. EPAK provides the mutual benefits of enhancing the flexibility of Kerberos and increasing the viability of alternate authentication systems as they move to the enterprise.

Skuna, Jiraphan. "International joint venture negotiation behaviour outcome : the role of bargaining power, culture and trust : qualitative case studies". Thesis, City University London, 2000. http://openaccess.city.ac.uk/8224/.
Testo completoAbstract (sommario):
Most of the literature on joint ventures (JVs) in developing countries has been viewed from the perspective of the foreign partners, ignoring the strategic imperatives and goals of the host country partners. Additionally, there has been very little research on international joint ventures (IJVs) in Thailand. Therefore, a study of the relationships between bargaining power, trust and culture affecting negotiation behaviour and outcomes (JV performance) could clarify and complement the results of past studies. It could lead foreign and Thai investors to better understand what they should do before and after entering into JVs, so as to achieve an effective performance (outcome), the success of IJV, cost minimization and profit maximization. This study examines the variables mentioned above in the context of service industries (e.g. construction, leasing, gas distribution), within the confines of joint venture theory and negotiation theory. The data was gathered using both questionnaires and in-depth interviews with a number of MDs and senior managers of JV firms. Both Thai and foreign parents were interviewed where possible. The result of the study shows that relationships between bargaining power, trust, culture, negotiation behaviour and performance (outcome) exist. A significant external factor affecting JV performance was also identified. Case studies were used as a research strategy for this study. 'Pattern matching logic' and 'explanation building' techniques were used for the analysis of data. In addition, data display technique was added to offer a clear understanding and picture of the results of the study. Regarding JV management and negotiation, this study demonstrated that each JV partner should pay attention and time to support the development of mutual trust and cultural understanding in order to avoid conflict and enhance a successful JV performance. This study also revealed the effect of bargaining power, trust and culture on JV performance mediated by negotiation tactics. This has received little attention in previous studies.

Smith, Bryan J. "Responding to Policies at Runtime in TrustBuilder". BYU ScholarsArchive, 2004. https://scholarsarchive.byu.edu/etd/24.
Testo completoAbstract (sommario):
Automated trust negotiation is the process of establishing trust between entities with no prior relationship through the iterative disclosure of digital credentials. One approach to negotiating trust is for the participants to exchange access control policies to inform each other of the requirements for establishing trust. When a policy is received at runtime, a compliance checker determines which credentials satisfy the policy so they can be disclosed. In situations where several sets of credentials satisfy a policy and some of the credentials are sensitive, a compliance checker that generates all the sets is necessary to insure that the negotiation succeeds whenever possible. Compliance checkers designed for trust management do not usually generate all the satisfying sets. In this thesis, we present two practical algorithms for generating all satisfying sets given a compliance checker that generates only one set. The ability to generate all of the combinations provides greater flexibility in how the system or user establishes trust. For example, the least sensitive credential combination could be disclosed first. These ideas have been implemented in TrustBuilder, our prototype system for trust negotiation.

Testo completoAbstract (sommario):
The purpose of this study is to create an understanding of how the interaction between PR consultants and PR service providers can affect the performance of a PR service, as well as showing how PR consultants and buyers can act to initiate and further develop an efficient collaboration. The study uses multimethod research and is based on a deductive approach. Empirical collection was conducted through a combination of structured and semi-structured interviews. The interviews were conducted on two respondent groups, one consisting of 5 PR consultants and the other consisting of 5 buyers of PR services. Each interview session was initiated with the structured questions and further elaborated with the semi-structured interviews. The results of the study show that to increase the chances of achieving a good service outcome of a public relations service, a collaboration is required where purchasers are involved in the development of the PR service. Furthermore, the respondents' views on whether clients are involved in the development of the PR service diverge. The purchasers felt that they were involved in the creative process, contrary to the PR consultants view, that the client’s involvement was limited. Similarly, to what extent the client was providing information to the creative process, there were differences in opinions. The customers considered that their ability to share information was good, while PR consultants considered it less good. The study showed that communication had a central role in the creation of a public relations service. In order to achieve efficient cooperation, both parties suggested that two-way communication is a prerequisite. All respondents felt that there are risks when purchasing a PR service since the outcome of the service cannot be guaranteed or measured until afterwards. Factors that proved to be significant for the initiation and further development of cooperation were trust and personal chemistry. The study intends to contribute knowledge and guidance on what constitutes as a working relationship between PR consultants and buyers of PR services. With this understanding, both parties can apply this knowledge to increase the chances of successful service outcomes.Syftet med denna studie är att skapa förståelse för hur samverkan mellan PR-konsulter och inköpare av PR-tjänster kan påverka resultatet av en PR-tjänst. Samt att visa på hur PR-konsult och inköpare kan agera för att initiera och vidareutveckla ett fungerande samarbete. Studien använde sig av en flermetodsforskning och baserades på en deduktiv ansats. Empiriinsamling genomfördes i form av en kombination av strukturerade och semistrukturerade intervjuer. Intervjuerna genomfördes på två respondentgrupper, en bestående av ett antal om 5 PR-konsulter och en bestående av ett antal om 5 inköpare av PR-tjänster. Varje respondent intervjuades vid ett intervjutillfälle som inleddes med de strukturerade frågorna och vidare fördjupades med de semistrukturerade intervjuerna. Studiens resultat visade, för att öka chanserna att nå ett bra tjänsteutfall av en PR-tjänst krävs en samverkan där inköpare är delaktig i skapandet av PR-tjänsten. Vidare framgick att respondentgruppernas syn på huruvida inköpare är delaktiga i framtagandet av PR-tjänsten divergerar. Inköparna ansåg att de själva generellt är delaktiga i skapandeprocessen till skillnad från PR-konsulterna som ansåg att inköpares delaktighet var mindre bra. Vidare framgick liknande meningsskiljaktigheter kring huruvida inköpare generellt delger information till PRbyrån vid skapandet av en PR-tjänst. Inköparna ansåg att dess förmåga att delge information var god, medan PR-konsulterna ansåg att den var mindre bra. Studien visade att kommunikationen hade en central roll vid skapandet av en PR-tjänst. För att åstadkomma ett fungerande samarbete menade båda parter att en tvåvägskommunikation är en förutsättning. Samtliga respondenter ansåg att det finns risker vid köp av en PR-tjänst då tjänstens utfall inte kan garanteras eller mätas förrän i efterhand. Faktorer som visade sig vara betydande för initiering och vidareutveckling av ett samarbete var tillit, förtroende och personkemi. Studien ämnar att bidra med kunskap och vägledning om vad som utgör en fungerande samverkan mellan PR-konsulter och inköpare av PR-tjänster. Med denna förståelse kan båda parter tillämpa denna kunskap i syfte att öka chanserna till ett lyckat tjänsteutfall.

Gustavsson, Emily, e Anja Mlivic. "Medelstora företags inköpsarbete och affärsrelation med en större leverantör". Thesis, Linköpings universitet, Företagsekonomi, 2015. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-120792.
Testo completoAbstract (sommario):
Bakgrund Under de senaste åren har inköp uppmärksammats allt mer. Ökade kravfrån kunder och högre konkurrens har lett till att företag ser fördelar mednära affärsrelationer. Däremot har medelstora företag influenser frånbåde stora och små företag och det är därmed svårt att veta vad de har förutgångspunkt i affärsrelationer. Litteraturgenomgången visar att detsaknas forskning för enbart medelstora företags inköpsprocess. Av denanledningen är det intressant att undersöka medelstora företagsinköpsarbete inriktat på affärsrelationer med en större leverantör, för attse hur båda parter upplever affärsrelationen samt om medelstora företagoch små företag kan klassas in i samma definition. Syfte Syftet med den här studien är att öka förståelsen för medelstora företagsinköpsarbete, där fokus ligger på deras affärsrelationer med en störreleverantör. Studien avser att öka förståelsen för hur en kund och dessleverantör upplever och hanterar affärsrelationen. Metod Studien har en kvalitativ ansats och bygger på en flerfallstudie medintervjuer från ett leverantörsföretag samt tre kundföretag, för att ökaförståelsen för kundföretagens inköpsarbete samt för att se hur respektivepart upplever affärsrelationen. Slutsats Studiens resultat visar att medelstora företag arbetar mycket med atteffektivisera inköp och ser inköp som en värdeskapande funktion. Därförbör de inte klassas in i samma definition som små företag. För att enaffärsrelation ska fungera bra krävs framförallt förtroende mellanparterna och att makt inte utövas.Background Purchasing has been more acknowledged during the last couple of years.Higher demands from customers have led to companies seeingadvantages with close business relationships. However, medium-sizedenterprises have influences from both big and small enterprises and it istherefore hard to know what starting position they have in businessrelationships. The literature review shows that research is lacking foronly medium-sized enterprise’s buying process. Therefore it isinteresting to study purchasing in medium-sized enterprises with focuson their business relationship with a larger supplier, to be able to see howboth parties perceive the business relationship and if medium-sizedenterprises can be classified in the same definition. Aim The aim with this study is to gain a greater insight of purchasing inmedium-sized enterprises, with a focus on their business relationshipwith a larger supplier. The study aims to gain a bigger insight of how acustomer and its supplier perceive and manage the business relationship. Methodology The study has a qualitative approach and is built on a case-study withinterviews from one supplier and three customers, to gain a biggerinsight of purchasing and to be able to see how each party perceive thebusiness relationship. Conclusion The results of the study show that medium-sized enterprises work a lot tomake purchasing more efficient and they all believe that purchasing is avalue adding function. Therefore they should not be classified in thesame definition as small-sized enterprises. One of the most importantcomponents in a business relationship is trust and power should not beused.

Noisette, Sandy David. "Performance et droit du travail". Thesis, Aix-Marseille, 2018. http://www.theses.fr/2018AIXM0160.
Testo completoAbstract (sommario):
La polysémie de la notion de performance est attachée au type de rationalités de la personne juridique s’y référant. Son caractère restrictif appauvrit la fonction protectrice du droit et rend concurrents les ordres juridiques et économiques. Il a comme effet d’opposer employeurs et salariés. Pourtant, il semblerait bien que le droit du travail permette de solidariser les objectifs d’efficacité économique à ceux de sécurisation du statut des travailleurs. Il sera alors loisible de promouvoir la coordination, sinon la coopération, au coeur du contrat de travail. Cet effet permet d’introduire de la flexibilité dans les relations de travail, tant individuelles que collectives, tout en préservant la volonté première des contractants : le statut économique du contrat en tire alors bénéfice. Cependant, afin de limiter les risques que les intéressés pourraient subir d’une relation dégradée, la dynamisation du contrat ne pourra se réaliser que sous l’égide de la bonne foi. A cette seule condition, l’efficience économique, tout comme l’efficacité juridique, pourront en être les conséquences. Il reste enfin nécessaire d’envisager cet idéal au cœur d’une autre réalité sociale ; cela rend la performance contingente. Son caractère global requiert d’abord des rapports apaisés au cœur de la gouvernance de l’entreprise, qui, en tant qu’institution, verra respectées les prérogatives de ses organes et l’autonomie de l’intérêt social. Il nécessite ensuite de s’adapter à un modèle réticulaire de l’économie, fortement marqué par la triangulation des relations de travailThe polysemy of the notion of performance is linked to the type of rationalities of the legal person referring to it. Its restrictive nature impoverishes the protective function of law and makes the legal and economic orders competitive. The effect is to oppose employers and employees. However, it may seem that labor law enables a connection between the objectives of economic efficiency to those of the security of the employees‘ status. Then, promoting the coordination or even the cooperation at the heart of the employment contract will be open. This consequence enables the introduction of flexibility in work relationships, both collective and individual, while maintaining the main aim of the contractors the contract economic status then benefits from it all. However, in order to limit the risks that the parties concerned may undergo from a deteriorated relationship, the dynamic development of the contract will only be able to happen under the auspices of good faith. Only then can economic efficiency as well as legal effectiveness be the consequences of it. It is still necessary to consider this ideal at the heart of another social reality ; this makes the performance contingent. Its global nature requires soothed relationships in the first place at the heart of the corporate governance, which, as an institution, will see the prerogatives of its organs and the autonomy of the social interest respected. It is then necessary to adapt to a network model of economy, strongly characterized by the triangulation of work relationships

Testo completoAbstract (sommario):
Through the critical and in-depth investigation of the production of my feature documentary film Father Joe and the Bangkok Slaughterhouse (2008–2019), and the short film Through the Eyes of Children (2008–2019), this exegesis explores the roles that trust, morals, and ethics play in negotiations between a documentary filmmaker and their subject in regard to the subject’s on-screen representation. It further investigates how these factors, in turn, inculcate the theme, content, and outcome of documentaries.
Through the Eyes of Children, filmed in Bangkok and Australia, is a thirteen minute film commissioned by Little Dot Studios, UK, and is to be considered as one of my key creative outputs as well as a proof-of-concept film for the longer feature documentary. The film is also part of the ten-year process of filming in and around the Mercy Centre and the slums of Bangkok. The feature documentary film, Father Joe and the Bangkok Slaughterhouse, although 75% shot, has not yet been completed. The process of attempting to produce this film constitutes a significant part of my research and reflection. Other key creative outputs include rough cut video clips, trailers and promos. The script/treatment written for this project is also part of my final creative output (see Appendix 1).
In my view, the ever-increasing growth and insatiable appetite for confronting and sensationalised media content has arguably resulted in an exponential rise in more ethically critical material. Therefore, I believe it is timely to reflect on how documentary filmmakers are representing this material and the subjects involved. A lack of ethical awareness on the part of a documentary filmmaker can have significant and disastrous implications, such as a subject withdrawing from the project or taking legal action following the distribution of the film.
The balance of power between the filmmaker and subject is complex and, in my case, has been evolving for over ten years. This longevity has reinforced and consolidated the relationship between my subject (Father Joe Maier) and I, creating a strong creative and symbiotic bond that has eased the filmmaking process and alleviated certain anxieties.
The depiction of influential and iconic subjects can often lead to miscommunication, power struggles, and escalating conflict. In this exegesis, I investigate ways in which these problems can be avoided and resolved. Recognising and managing anxiety for both subject and filmmaker reduces possible situations of misunderstanding and potentially harmful consequences.
Some of the questions that I reflect upon in this exegesis are: What roles do trust and friendship play in the process of establishing the filmmaker–subject relationship? How can tensions and anxieties between creative freedom and editorial control be best managed? What parameters are at a filmmaker’s disposal to avoid legal disputes? How do filmmakers reconcile moral and ethical decisions in the disclosure of confidential and sensitive information? How does the perception of power influence the creative and cultural decisions of the filmmaker? And, in my case, how do I transform from being a white ‘farang’ outsider in a Thai slum to having inner sanctum ‘insider’ status while maintaining an objective perspective?Thesis (Masters)

M’interrogeant sur l’inflation du mot « médiation », j’ai passé en revue quelques unes des pratiques les plus courantes invoquant un terme dont j’ai pu en constater, dans certains cas, l’usage abusif. À partir de là, j’ai tenté de tracer les contours d’un concept en mal de définition. J’ai ainsi dégagé deux caractéristiques intrinsèques de la médiation, à savoir la triangularité et la non-directivité ainsi que ses deux prérequis que sont le libre consentement des participants et la légitimation du médiateur. Par ailleurs, j’ai constaté que la médiation ne s’appliquait pas qu’aux situations conflictuelles et que son enjeu n’était pas exclusivement affectif. Il peut être également matériel, donnant alors lieu à une médiation de type « négociatif ». En croisant ces deux variables, j’ai proposé une typologie des pratiques de médiation. Dans une seconde partie de ma thèse, je me suis livré à une analyse phénoménologique de la médiation, me servant de l’enregistrement de jeux de rôles. Cette analyse m’a conduit à élargir mon champ de vision, d’une «médiation» comprise comme « action du médiateur » à une réalité plus complexe que j’ai appelée « situation médiative » où le médiateur agit autant sur les participants qu’il est agi par eux. Cette situation, loin de se réduire à une pratique instituée, constitue un véritable phénomène social, fréquent dans la vie courante. La confiance que les participants accordent au médiateur, le rôle qu’ils lui font jouer en tant que « base de sécurité » comme alternative au face à face et sa fonction d’étayage de la communication constituent des conditions essentielles de la situation médiative avant même les techniques de médiationWondering about the increasing use of the word « mediation », I reviewed some of the most common practices referring to this word which was, in some cases, misused. On this basis, I strived to draw the outline of a concept in need of definition. In doing so, I identified two characteristics of mediation, namely the triangularity and the non-directivity, as well as its two prerequisites, i.e. the consent of the participants and the recognition of the mediator. Moreover, I noted that mediation does not apply only to situations of conflict and that its stake is not exclusively emotional. It could be material, leading to a negotiating mediation. Crossing these two variables, I then propose a typology of mediation practices. In a second part of my thesis, I set up a phenomenological analysis of mediation, using video recordings of role playing. This analysis led me to broaden my own perspective, from a mediation as « mediator’s action » to a more complex scenario that I called « mediative situation », where the mediator influences the participants and is in turn influenced by them. This situation, far from being restricted to an established practice, is indeed a social and frequent phenomenon. The confidence the participants have in the mediator, the role they give him/her as a “secure base” and as an alternative to the face to face situation, and his function in supporting communication, lay the basic condition of the mediative situation, a long way ahead of mediations techniques

Testo completoAbstract (sommario):
In May 1996 the AIDS Council of NSW launched Talk Test Test Trust ???Together (TTTT), an HIV prevention campaign aimed at decreasing risk of infection within gay men???s relationships. The rationale behind TTTT was ???negotiated safety???: that it was safe not to use condoms for anal sex in primary relationships if specific steps were followed. TTTT generated contestation within AIDS Councils in Australia and New Zealand, but also amongst researchers, policy makers and gay communities. Arguments about TTTT and negotiated safety appeared logical and reasonable and did not fall neatly along an Australia/New Zealand divide. This study used a qualitative approach to interview key HIV educators in New South Wales who were involved in the development of TTTT and New Zealand educators who did not promote negotiated safety. This thesis argues that in order to understand the contestation around negotiated safety and TTTT it is necessary to understand the broader social and historical factors that shape HIV prevention contexts and practice. These include factors arising from the epidemic itself (which, to some extent, were responsible for the difference between Australia and New Zealand) such as the increasing complexity of gay men???s risk reduction strategies, the rise of a positive voice, and impact of treatments and factors associated with and the broader context such as the rise and continuing history of a gay political and social movement and associated identity and community formation, and later, fragmentation, changing concepts of love, intimacy and relationships and of risk and the uncertainty, anxiety and fear from living in a complex individualised detraditionalised world. This approach will show that a focus on a dynamic epidemic, and the broader social and historical context can shed light on arguments made about negotiated safety and TTTT. Further, applying Bourdieu???s formulation of the complex interaction of habitus, fields and practice (1977) makes sense not only of the arguments made about negotiated safety and TTTT, but of educator practice and of HIV prevention, of the broader HIV and AIDS sector, and of how societies continue to learn to live with and adapt to the epidemic.

Testo completoAbstract (sommario):
Negotiations in real life are generally perceived as distributive tasks that produce winners and losers. Nevertheless, in almost all cases there is an opportunity to expand the joint outcome through cooperation; reaching a win-win agreement. The aforementioned characteristic of the negotiation task is similar with what is observed in a social dilemma, situations where individual self-interesting behaviour leads to inferior collective results. Therefore, elements from both phenomena can be used in order to advance the state of art on how to achieve win-win agreements in Labour-Management disputes. An important factor that can be seen as a necessary condition in order to achieve cooperation between parties is the existence of some level of trust. By adopting a deductive approach, a number of variables which influence negotiations between labour and management were isolated. These variables served as the elements for constructing a proposed theory that through a Decision Support System (DSS) will facilitate integrative agreements by fostering trust between the negotiators. In order to test the validity of the proposed theory, two research questions have been addressed aiming to verify; a) the set of variables used in the proposed theory and b) the facilitation of integrative agreements through fostering trust. The proposed research questions were tested through: i) a survey that was distributed in three countries, ii) a numerical experimentation with all possible outcomes and iii) by a set of interviews that aimed to provide deeper insight in the problems under examination. The results from the survey questionnaire and the information elicited by interviewing experts worked as confirmatory evidence in order to verify the validity of the set of variables. The numerical experimentation, combined with statements by the experts that participated in the interviews revealed confirmatory evidence for the ability of the proposed theory to foster trust and, thus, facilitate integrative results.

Testo completoAbstract (sommario):
Pain is one of the main reasons that adults seek health care, yet the management of chronic nonmalignant pain (CNMP) is framed by epistemological, ontological, ethical, and clinical uncertainties. As a subjective experience, CNMP presents challenges for both patients and health care providers. Opioid analgesics are commonly prescribed for CNMP. However, recent research questioning the long-term benefits of opioids for CNMP and the rapid rise in public health harms from prescription opioid abuse have led to concerns about iatrogenic addiction, drug-seeking behaviour, and medication diversion. Such concerns pose risks to the patient, to the health care provider, and to society, and may threaten the trust that provides the moral foundation of the therapeutic relationship. Drawing upon an interdisciplinary literature and methods from both bioethics and empirical neuroethics, this in-depth, multi-component single study focused on adults living in an urban setting in the Lower Mainland of British Columbia, Canada. Semi-structured interviews (N=27) were conducted with participants with chronic low back pain to explore their experiences of trust and trustworthiness in CNMP management. Grounded theory analysis of the data yielded four major themes: (1) fidelity and iatrogenic suffering; (2) communicating the invisible and subjective condition of chronic pain; (3) motive, honesty, and testimony; and (4) stigmatized identities. The findings were response-validated by two feedback groups comprising re-contacted interview participants (N=4) and physician specialists drawn from the same setting who care for patients living with CNMP and addiction (N=6).
Qualitative analysis suggests that trust in CNMP management is challenged when patients perceive that their accounts of pain and suffering are considered by health care providers to lack credibility, feel unfairly accused of being deceptive, or sense a combination of both lack of credibility and deception.
The dissertation concludes with a discussion of the practical implications of these findings in the context of the broader health care system, and with a proposal for how a trust- centred ethics of CNMP management can involve greater epistemic humility toward improved patient care.

Testo completoAbstract (sommario):
The enormous growth of the Internet and the World Wide Web has provided the opportunity for an enterprise to extend its boundaries in the global business environment. While commercial functions can be shared among a variety of
strategic allies - including business partners and customers, extranets appear to be
the cost-effective solution to providing global connectivity for different user groups.
Because extranets allow third-party users into corporate networks, they need to be extremely secure and external access needs to be highly controllable. Access control and authorisation mechanisms must be in place to regulate user access to information/resources in a manner that is consistent with the current set of policies
and practices both at intra-organisational and cross-organisational levels.
In the business-to-customer (B2C) e-commerce setting, a service provider faces a wide spectrum of new customers, who may not have pre-existing relationships established. Thus the authorisation problem is particularly complex. In this thesis, a new authorisation scheme is proposed to facilitate the service provider to
establish trust with potential customers, grant access privileges to legitimate users and enforce access control in a diversified commercial environment. Four modules with a number of innovative components and mechanisms suitable for distributed authorisation on extranets are developed:
* One-shot Authorisation Module - One-shot authorisation token is designed as a flexible and secure credential for access control enforcement in client/server systems;
* Token-Based Trust Establishment Module - Trust token is proposed for server-centric trust establishment in virtual enterprise environment.
* User-Centric Anonymous Authorisation Module - One-task authorisation key and anonymous attribute certificate are developed for anonymous
authorisation in a multi-organisational setting;
* Agent-Based Privilege Negotiation Module - Privilege negotiation agents are proposed to provide dynamic authorisation services with secure client agent environment for hosting these agents on user's platform

In the context of a very competitive market, having teams very well prepared and properly allocated is critical to the survival of businesses. This study aims to identify the repercussion on customer satisfaction and results of companies, from the knowledge of the people working on the front line of these companies, those professionals who play an important role in negotiation, identifying what they value in a subjectively negotiation. Using the tool SVI (Subjective Value Inventory) developed by Curhan et al (2006), from the dimensions of independent and interdependent self-image, attempts to identify the subjective values of the negotiators of a Brazilian retail bank, responsible for a significant part of the negotiations and results of the company in relation to feelings about themselves (Self), the instrumental results, and the process and relationship (Rapport), using interpersonal trust as a moderator in this relationship. Once identified, found results will be related to the customer satisfaction. The purpose of seeking this correlation is due to the assumption that the company exists only because of the customer. For this purpose, it was conducted a quantitative survey, with the application of a structured and closed questionnaire to 532 of the bank negotiators from that bank, who work in the states of Santa Catarina, Rio de Janeiro and Maranhão, responsible for relationship, prospecting and conducting business with institution’s customers, personal, small business and government. Data were analyzed using statistical techniques, using the method of Partial Least Squares. It was observed that over forty percent of customer satisfaction is explained by the subjective values of the negotiators. The study showed, among others results, that business managers with self-image independently value the Self and instrumental results in a negotiation, and interpersonal trust cognitive negatively moderates this relationship. Still, Rapport is valued in a negotiation by those business managers with interdependent self-image and this appreciation in a negotiation is positively related to customer satisfaction.
No contexto de um mercado tão competitivo, ter equipes bem preparadas e alocadas adequadamente é fundamental para a sobrevivência das empresas. O presente estudo objetiva identificar o reflexo na satisfação dos clientes e nos resultados das empresas, a partir do conhecimento das pessoas que trabalham na linha de frente dessas empresas, aqueles profissionais que exercem um papel importante de negociação, identificando o que eles valorizam subjetivamente em uma negociação. Por meio da ferramenta SVI (Subjective Value Inventory), desenvolvida por Curhan et al (2006), a partir das dimensões de autoimagem independente e interdependente, busca-se identificar os valores subjetivos dos negociadores de um banco de varejo brasileiro, responsáveis por parte significativa das negociações e dos resultados da empresa, relativamente aos sentimentos sobre si mesmos (Self), aos resultados instrumentais, e ao processo e relacionamento (Rapport), utilizando a confiança interpessoal como moderadora nessa relação. Após identificados os valores subjetivos desses negociadores em negociação, relacionar os resultados encontrados com a satisfação dos clientes. Para isso, foi realizada uma pesquisa quantitativa, com a aplicação de um questionário fechado e estruturado a 532 negociadores desse banco que atuam nos estados de Santa Catarina, Rio de Janeiro e Maranhão, responsáveis pelo relacionamento, prospecção e realização de negócios com os clientes da instituição, nos segmentos pessoa física, micro e pequenas empresas e governo. Os dados foram analisados a partir de técnicas estatísticas, utilizando-se o método dos Mínimos Quadrados Parciais. Observou-se que mais de 40% da satisfação de cliente é explicada pelos valores subjetivos dos negociadores. O estudo apontou como resultados, dentre outros, que os gerentes de negócios com autoimagem independente valorizam o Self e os resultados instrumentais em uma negociação, e que a confiança interpessoal cognitiva modera negativamente essa relação. Ainda, que aqueles gerentes de negócios com autoimagem interdependente, valorizam o Rapport em uma negociação e que essa valorização está positivamente relacionada com a satisfação dos clientes.

Fiddler, Jay. "Negotiating trust in the Canadian blood system : governance and the politics of public accountability in the wake of the tainted blood scandal". Thesis, University of British Columbia, 2011. http://hdl.handle.net/2429/34787.
Testo completoAbstract (sommario):
Blood and its derivatives are critical public health resources. Therefore, the ability to ensure a sufficient and safe supply of blood is a central role for governments and blood organizations. The challenges involved in ensuring this complex resource became evident following the contamination of blood supplies in the 1980s and 1990s with the Human Immunodeficiency Virus (HIV) and Hepatitis C (HCV). In Canada, this became known as the “tainted blood scandal”, with approximately 2000 people infected with HIV and more than 160,000 people infected with HCV through contaminated blood products. This crisis resulted in the loss of public trust in the Canadian blood system and in those responsible for its management. The public outcry led blood experts and governments to adopt more efficient ways of anticipating and managing emergent threats to blood safety by implementing the precautionary principle. These efforts also aimed to retain their legitimacy and rebuild public trust by integrating formal mechanisms of stakeholder engagement in risk governance.
By using stakeholder engagement as a case study, this study focuses on the institutional processes of rebuilding trust in the Canadian blood system following the tainted blood scandal. The analysis describes competing ideas about trust, risk and responsibility in the blood system and traces the influence of stakeholders groups such as the hemophilia community and other blood consumer organizations. The findings suggest that stakeholder engagement primarily serves the interests of the blood operator by enhancing its reputation as a responsible manager of the blood system. It also diverts attention away from the role of the state in managing blood risk through expert systems and a policy of strict adherence to the precautionary principle. The analysis also demonstrates that stakeholder engagement can also serve as an alternative form of power and influence for hemophilia consumers. As victims of tainted blood, these consumers are able to play a unique role in endorsing blood safety and thus helping to rebuild reputation and public trust. However, because of this role they may also become an organizational risk if their interests are not reflected in blood policy.

Automated trust negotiation is proposed to be used under the framework of distributed systems for the issues of access control and authentication. The most important demand is to achieve more resource sharing and collaborative computing between many virtual organizations. In order to implement the requirement, we need a fast and effective mechanism for the large number of dynamically distributed individuals or organizations to establish trust; in addition, the trust relationship between many network services often dynamically establish and adjust, so we need to rely on negotiation to achieve the purpose of collaboration or resource sharing and also can make maintenance of self-control, privacy and other security issues. Communicating parties in the negotiation process describe each other''s characteristics that should be satisfied through the specified access control policies, and the characteristics usually consist of credentials. Via a series of descriptions and fulfillments, finally the two parties establish a mutual trust relationship. So far, the research of automated trust negotiation interests include infrastructure, access control policy and credentials, negotiation strategies, negotiation protocol, negotiation systems…etc., this article focuses on the research about the assignments of access control policies and the processes of negotiation strategies in the trust negotiation. Access control policies are assigned to regulate credentials that should be satisfied while accessing protected resources; however, in order to avoid that the policy consistency checking mechanism is too complex in the cross-region, it is necessary to make reasonable constraints for policy assignments. Nevertheless, it cannot really concretely assign policies for all the resources only through setting up the policy requirements and representing the policy format, and authority should be also considered in policy assignments. To make the automated trust negotiation be more specific implementation, this paper proposed proprietary and concrete policy assignments and implement them with the concept "classification authority". On the other hand, in order to make the process of establishing trust rationalization, a specific negotiation strategy will be proposed. In the past, a variety of proposed negotiation strategies had their own demands, but there are still several flaws for the design of the operation. For example, the Eager strategy, it has high efficiency, but the reason that it has disclosed irrelevant credentials in the handshake mechanism results in a poor security; the PRUNES, it has high security defense, but it makes low negotiation efficiency based on the concept of backtracking. In this paper, we retain the advantages of each of the negotiation strategy and try to integrate a hybrid negotiation strategy. Based on Parsimonious strategy, we have made a binding using the features of Eager and PRUNES strategies; in addition, we add iteration computing to improve the negotiation efficiency. In the experimental results, we have proved that the proposed hybrid negotiation strategy does take into account the performance and security.

In recent years, there are more and more web services which have participated in Internet. Automated Trust Negotiation (ATN) enables independent entities working together without human/manual interactions and prior trust relationships. The credentials are treated as tokens to establish trust between two strange entities, which can make connections and do business together if ATN is successful. A good ATN negotiation strategy should exchange sensitive credentials on an as-needed base. In this paper, we proposed a trust third party agent, Advanced NegotiatioN Agent (ANNA), for the advanced negotiation. The experiments show that ANNA is able to decrease unnecessary credential exchange and reduce the communication overhead in the trust negotiation process.

Testo completoAbstract (sommario):
In Australia, home and community aged care has been a growing sector for the past two decades. To achieve higher levels of efficiency and improve the quality of care, remote monitoring systems for elderly offer interesting solutions. The data collected by the monitoring system are transmitted to the healthcare provider and stored on the healthcare provider’s server in the form of patients’ Electronic Health Records (EHR). With such a system, healthcare professionals can remotely access each patient’s EHR on their mobile devices, for instance when they are at the patients’ homes. They may need to access patients’ EHR for obtaining the history of the patient’s medical records or modifying the patient’s EHR. It is important to secure the transmission of the patient’s EHR between the healthcare provider server and the mobile device being used by the healthcare professional, as communication is via unsecure networks, such as the Internet. It is also important to ensure that a patient’s EHR is only disclosed to the authorized entities. Therefore, obviously, security services, such as privacy protection during transmission of data and remote authorized access to patients’ EHR are of paramount importance. Other security requirements that need to be addressed relate to the nature of mobile devices and their vulnerabilities to loss and theft. The approaches proposed in this study ensure that patients’ EHR are only disclosed to the authorized healthcare professional, on the registered device, at the appropriate locations. They ensure the confidentiality of information by securing its transmission, using Transport Layer Security (TLS) as the underlying protocol. Building on the strengths of this protocol, a trust negotiation approach is developed. This approach authenticates the person receiving the care, the person administering it, the mobile device used in accessing the health information, as well as the location where the healthcare is administered. This combination results in significant improvements in overcoming security related concerns compared to the traditional identity-based only access control techniques. The improvements in the security of the remote monitoring systems are achieved by providing extra protective features to the access control and authorization process before the release of any data over unsecured networks. For verification purposes, a mobile application is developed. This application gives healthcare professionals secure remote access to the EHR of the monitored elderly patients. These experimental works confirm that by applying the proposed trust negotiation approach, the expected analysis results can be achieved. The developed application is also practical and easy to adopt, as users are not required to have any additional knowledge or expertise in the use of the underlying technologies. This is also important, as in general, most healthcare professionals cannot be considered as experts in network security areas.

The technology of choosing trustworthy Service has become a very important topic in the fields of e-commerce and pervasive computing. Automated trust negotiation (ATN) is an approach to help the client to choose trusty services via exchanging of sensitive credentials satisfying access control policies. In this paper, we proposed NTA (negotiation transparent agent) to improve the drawbacks of the dynamic programming ATN implementation as well as to accommodate different requirements (such as cost and communication). The effectiveness of the proposed scheme has been demonstrated in our simulation studies that have successfully used this NTA approach to adopt sustainable practices in pervasive computing environments.

In order to enhance the enterprise efficacy, this study aims to explore the relationship of personality trait, trust tendency and negotiation strategy based upon the frameworks of big five personality traits – agreeableness, conscientiousness, extraversion, neuroticism, and openness; trust tendencies – characteristic facet and emotional facet; five negotiation strategies – competitive, collaborative, compromised, avoided and accommodative negotiation strategies. The survey questionnaires were distributed to the participants—290 college students from two universities in central Taiwan. After data analysis, the result shows the higher a negotiator holds agreeable and neurotic personality trait, the lower he/she would choose competitive negotiation strategy; the higher a negotiator holds agreeable personality trait, he/she tends to take an avoided negotiation strategy. Furthermore, the higher a negotiator holds extrovert personality trait, he/she tends to take a collaborative negotiation strategy; the higher a negotiator holds openness personality trait, the lower he/she would choose avoided and accommodative negotiation strategy, instead, he/she would take competitive negotiation strategy. In conclusion, the study shows the existence of significant relationship among the five personality traits, trust tendencies and different choice of negotiation strategies. However, the trust tendency a negotiator has toward the trustee does not influence the effect of the choice of negotiation strategies. This study shows that the factor which influences the choice of negotiation strategies lies upon the negotiation issues, priority, goal or negotiation timing, not upon the trust tendencies.

More and more users are drawn to these networks because of the convenience that P2P systems bring on. However, they also bring up some problems. A typical P2P system allows mutually distrustful parties to join or leave freely. Furthermore, the selfish nodes which only want to utilize other peers’ resources without any contribution have greatly jeopardized the fairness of most P2P networks. These problems have led to the development of reputation mechanisms which detect misbehavior and punish selfish peers, and also to encourage good ones. There are some reputation mechanisms in P2P systems. Most of them maintain their trust based on peers’ own experience and other peer’s recommendations. Such reputation mechanism could give users some knowledge about other users’ past behaviors. Trust negotiation is orthogonal to current reputation-based approaches. It is proposed to handle access control and authentication in open and distributed systems. In this paper, we try to combine both mechanisms. We think trust negotiation can be used together with reputation mechanisms to build trust in a P2P system. In this paper, we proposed a reputation scheme based on trust negotiation for P2P system. We propose an evaluation mechanism for a reputation system that objectively maps each peer’s activity in the P2P network to a reputation level. We maintain a mechanism based on trust negotiation. If a successful negotiation was completed between two peers¸ both peers can get licenses. Peers can raise their trust by collecting licenses. If peers only download resources from other peers, they can’t obtain higher reputation level. Peers with lower reputation level can’t access those with higher reputation level. This mechanism can efficiently arrest selfish behaviors of some peers. We also apply reputation level to trust negotiation. We use reputation level to make trust negotiation more reliable.

This study investigates the extent of the impact of the national culture in the formation of the trust that business people are likely to extend to exchange partners in business negotiations and, consequently, how the level of such trust influences the likelihood of using certain questionable tactics in domestic and foreign negotiations. The sample of this study consists of business people from different companies, industries, sectors of Taiwan and Mexico, 280 Samples were collected from organizations, government office and companies in Mexico and in Taiwan. Based on survey data collected from businesspeople from Mexico, and Taiwan, this study shows that trust is culturally embedded and has a negative relationship with the likelihood of using certain questionable negotiation behavior tactics. The study found that Mexican negotiators are less likely to use questionable negotiation tactics in domestic negotiations as compared to foreign negotiations. On the other hand, the intended negotiation behaviors of Taiwan negotiators were not found to vary significantly across domestic and foreign negotiations. The findings of the study underscore the importance of building relationship with exchange partners, especially with the Mexican business people, while dealing with Taiwan business people; we should focus more on issues and tasks rather than on a relationship.

In this thesis, outsourcing refers to a process in which a company delegates its nonessential labor service or manufacture to a third party. It is a mixture of competition and collaboration. Business units must cooperate for survival, and sometimes it even evolves opportunistic behaviors; therefore, the anticipated mutual goal of outsourcing negotiation is to maximize interests, to minimize risks, and to achieve co-survival and growth, which is also the goal of this study. Based on the transaction cost approach developed by Williamson (1985) and the theory of embeddedness from Granovetter (1985, 1992), this author analyzed the formation of outsourcing negotiation strategies from two aspects: power hierarchy (interest-oriented) and trust relationship (relationship-oriented). The author adopted the methodology of case study in this study, integrated Grounded Theory with coding process to conduct the analysis, and obtained following propositions: 1. The more relationship-oriented one party is, the more economic loss this party can bear. If the other party’s “power hierarchy” is relatively higher than ours, the more stable the trust in the “trust relationship” is, the higher tendency we would be relationship-oriented and to take the strategy to cooperate. 2. The more interest-oriented one party is, the less economic loss this party can bear. If the other party’s “power hierarchy” is relatively lower than ours and the resources are under our control, we would take the strategy to cooperate, compromise, or even compete; meanwhile, the other party would take the strategy to cooperate, compromise, or even make a concession. 3. The greater the power hierarchy difference is, it would be less beneficial to maintain the trust relationship, and more likely to become interest-oriented.. The author found that negotiation strategies were derived from co-comparing and evaluating the orientations of interest and relationship. Concrete relationship reflected the change of negotiation expectation (trust). And whether a consensus could be reached depended on each party’s satisfaction on the result, and there was a positive relationship between satisfaction and the gain of a negotiation. The author concluded that cooperation was the negotiation strategy with the highest gain. Trust relationship was not only beneficial to maintain a transaction and outsourcing stability, it also acted as the pivot of a lever to become the key leverage. It helped with the use and choice of strategies to gain a better position and the lowest cost as well.

Web Services propose a framework for the standardisation of interfaces and
interaction, and for publishing software componen1S as services on the Internet By
using this framework, composite servi<:es that make use of more than one Web service
can be created. Although a composite Web service may provide a unified service to
the service requestor~ it cannot be viewed as a single unified entity when its
trustworthiness is evaluated, since its constituent services may differ in their nonfunctional
attributes.
Based on the context of trust (which includes security, reliability, quality of servi~e.
etc.), information has to be collected from the constituent services of a composite
Web service. Trust negotiation is perfonned to gather infonnation from these
services, with the ultimate goal of establishing trust relationships with them.
In this dissertation~ the Web Services framework is analysed to determine its support
for trust negotiation in any trust context. A trust negotiation procedure is subsequeotly
presemed. which can be applied in a composite as well as an elementary Web service.Computing

Testo completoAbstract (sommario):
No presente trabalho de investigação propõe-se o estudo do tema “A tutela da confiança na negociação de contratos”. Num processo de negociação, à semelhança de muitos aspetos da vida, estabelecer e manter a confiança é um ponto de partida fundamental no desenvolvimento de relações jurídicas que se estabeleçam entre os indivíduos. A tutela da confiança é, nas palavras de MOURA VICENTE, “uma exigência sine qua non para a segurança do tráfico jurídico e uma vida colectiva pacífica e de cooperação”. Num processo de negociação, parte-se do princípio de que todas as partes envolvidas serão honestas, estarão de boa-fé e que irão cumprir com os respetivos compromissos contratuais. Quando tal não se verifica, surgem questões significativas que tornam difícil ou minam todo o processo negocial, ferindo-se as legítimas expectativas de conclusão futura do contrato. A responsabilidade pré-contratual representa, pois, a responsabilidade por lesão à liberdade de negociação alheia, alcançada por meio de um comportamento que difere dos cânones da seriedade, lealdade, honestidade, implementada durante as negociações e formação do vínculo contratual, que irá ser abordado quando esta responsabilidade tem na sua origem a rutura ilegítima das negociações. A tutela da confiança e o princípio da boa-fé ganham, assim, relevo na proteção dos legítimos interesses contratuais contra comportamentos abusivos e enganosos nas negociações pré-contratuais. Com este trabalho propomo-nos analisar a tutela da confiança e o princípio da boa-fé em todo o processo negocial, à luz do nosso ordenamento jurídico."The protection of trust in contract negotiation” In this research work it is proposed to study the theme “the protection of trust in contract negotiation”. In a negotiation process, like many aspects of life, establishing and maintaining trust is a fundamental starting point in the development of legal relationships that are established between individuals. The protection of trust is in the words of MOURA VICENTE “a sine qua non requirement for the security of legal trafficking and a peaceful and cooperative collective life”. In a negotiation process, it is assumed that all parties involved will be honest, will be in good faith and will comply with the respective contractual commitments. When this is not the case, significant issues arise that make it difficult or undermine the entire negotiation process, undermining the legitimate expectations for the future conclusion of the contract. Pre-contractual responsibility, therefore, represents responsibility for injury to the freedom of others to negotiate, achieved through behaviour that differs from the canons of seriousness, loyalty, honesty, implemented during negotiations and formation of the contractual bond that will be addressed when this responsibility has its origin in the illegitimate rupture of the negotiations. The protection of trust and the principle of good faith thus gain importance in the protection of legitimate contractual interests against abusive and deceptive behaviour in pre-contractual negotiations. With this work propose to analyze the protection of trust and the principle of good faith in the whole negotiation process, in the light of our legal system.

Testo completoAbstract (sommario):
This thesis investigates the role of accounting information in the automotive industry restructuring of 2008 and 2009 in Canada. The crisis in the automotive industry led to government-funded restructurings for two of the top manufacturers in North America, effectively adding the government as a third party to the negotiations. Following a series of negotiations that occurred between AutoCo and UnionA, I conduct a case study that examines the individual actors’ use of accounting inscriptions in negotiations, as well as explore the dynamic interaction between accounting and trust at the negotiation table. The use of actor network theory highlights the individual actors, their actor-networks, accounting inscriptions and the continuous translation process inherent in labour-management negotiations. Accounting inscriptions are shown to play a central role in negotiations, particularly as a forum for bringing the actor-networks together. Furthermore, I explicate the notion of tactical trust, as it emphasizes the assessment, monitoring, and adjustment inherent in decisions to trust actors within dynamic business contexts.
I also investigate the roles that the Canadian government played throughout the restructuring of the automotive industry. Through an in-depth case study of the restructuring from its antecedents through to outcomes, the research focuses on the roles of the government officials in the negotiations between the company and the unions, and their use of accounting information. The empirics highlight that the government not only acted at a distance but utilized sovereign power and direct intervention to achieve their objectives in the automotive industry restructuring. I find that the accounting served as the flexible substitute for the government’s presence at the negotiations table while they were acting at a distance and is used as an immutable parameter when the government directly intervened. This paper extends the governmentality literature by highlighting the coercive character of government actions, technologies and programs, and the notion of government in action. I consider the implications of these research findings on the labour-management negotiations, accounting, actor network theory and governmentality literature. In conclusion I also highlight various avenues of future research.Thesis (Ph.D, Management) -- Queen's University, 2013-10-09 20:46:13.009
