Smart home systems (SHS) have become an increasingly important technology in modern life. Apart from safety, security, convenience and entertainment, they offer significant potential benefits for the elderly, disabled and others who cannot live independently. Furthermore, smart homes are environmentally friendly. SHS functionality is based on perceiving residents’ needs and desires, then offering services accordingly. In order to be smart, homes have to be equipped with sensors, actuators and intelligent devices and appliances, as well as connectivity and control mechanisms. A typical SHS comprises heterogeneous services and appliances that are designed by many different developers and which may meet for the first time in the home network. The heterogeneous nature of the systems, in addition to the dynamic environment in which they are deployed, exposes them to undesirable interactions between services, known as Feature Interaction (FI). Another reason for FI is the divergence between the policies, needs and desires of different residents. Proposed approaches to FI detection and resolution should take these different types of interaction into account. Negotiation is an effective mechanism to address FI, as conflicting features can then negotiate with each other to reach a compromise agreement. The ultimate goal of this study is to develop an Agent-Based Negotiation Approach (ABNA) to detect and resolve feature interaction in a SHS. A smart home architecture incorporating the components of the ABNA has been proposed. The backbone of the proposed approach is a hierarchy in which features are organised according to their importance in terms of their functional contribution to the overall service. Thus, features are categorised according to their priority, those which are essential for the service to function having the highest priority. An agent model of the ABNA is proposed and comprehensive definitions of its components are presented. A computational model of the system also has been proposed which is used to explain the behaviour of different components when a proposal to perform a task is raised. To clarify the system requirements and also to aid the design and implementation of its properties, a formal specification of the ABNA is presented using the mathematical notations of Calculus of Context-aware Ambient (CCA), then in order to evaluate the approach a case study is reported, involving two services within the SHS: ventilation and air conditioning. For the purpose of evaluation, the execution environment of CCA is utilised to execute and analyse the ABNA.

In the past decade, electronic negotiation has become an important research topic in the field of information systems. A desirable goal of negotiation agents is to understand their owners' requirements, and to learn their opponents' behavior, thereby lessening the involvement of human beings. Studies on human negotiation bring out that several issues can affect a human's negotiation behavior, including learning an opponent's behavior, exerting power on an opponent, and setting an individual goal to improve the level of accomplishment. Research on incorporating these issues into negotiation agents is, however, still at an infancy state. We therefore take up this topic in this thesis. Researchers have proposed many different negotiation agents that follow a preset behavior based on human models of negotiation. In this thesis, we consider one such model, known as the time-dependent-tactical model, which is used by human negotiators and in which the values of the negotiating issues are determined based on the time elapsed in the negotiation. A learning mechanism for this model might be beneficial, because this model is frequently used in electronic negotiation. Thus, we propose heuristic algorithms that estimate the parameters of an agent's time-dependent-tactical model, and that then react to the estimated parameters for achieving higher negotiation performance. Besides learning, we incorporate two other factors that have been found to affect a human negotiation outcome. These are situational power, which represents differences in negotiators' status based on market conditions, and goal constraints, which stand for the levels of accomplishment negotiators try to strive for. To validate the impacts of learning, situational power and goal constraints in electronic negotiation, we first present how to integrate these features into negotiation agents, and then conduct simulations. With 187,500 simulation runs, we observe that our learning algorithms are effective in improving both individual and dyadic negotiation performances. For the effects of situational power and goal constraints, we obtain congruent results between human and electronic negotiations. By incorporating learning into situational power and goal constraints, we achieve significant joint effect between learning and situational power as well as that between learning and goal constraints. In summary, this thesis provides three primary contributions to the fields of information systems and electronic-commerce research. First, we have designed algorithms for learning an opponent's negotiation behavior. Second, our learning algorithms are found to be effective in improving negotiation performance. Third, we have shown how learning can be integrated with situational power and goal constraints, although this is not a major focus in this study. Finally, the agreement on the joint effects of learning, situational power and goal constraints between human and electronic negotiations suggests that our integrated design of the agent appears to be effective.

This thesis is concerned with how entrepreneurs’ performance - the act of impression (Goffman, 1959a), is accomplished through emotion management - the work that an individual does to manage and display situation-appropriate feelings (Hochschild, 1983). There is literature that suggests that understanding entrepreneurs’ emotion management is needed (Goss, 2008; Hampson & Junor, 2005) with Goss (2008) maintaining that entrepreneurs’ management of emotion is integral to their activities. This thesis provides the specific consideration that has been lacking. Empirically, drawing on data obtained from entrepreneur interviews, this study extends Hochschild’s (1983) list of occupations that conduct emotion management to the field of entrepreneurship. Theoretically, Hochschild’s (1983) theory of emotion management has been reconceptualised to become more interactionally sensitive. Influenced by symbolic interactionism (Blumer, 1969) with experiences, interpretations of meaning and actions drawn on to show how performance and emotion management emerge in interaction. Emotion management is conceived of as a negotiation where both ‘normative’ pressures such as the two sets of entrepreneurship feeling rules that have been identified – feeling of engagement and feeling of detachment, and interpretive conceptualisation, are taken into account in the development of a shared scheme of understanding. Goffman’s (1959a) ideas around the presentation of self have been drawn on in rendering visible entrepreneurs’ performance as embodied, relational co-operative, and professional and appropriate. Entrepreneurs are negotiators conceiving of their performance and emotion management as resourceful, negotiated, self-interpretive work. This negotiated work is a process of ‘fluid equilibrium’, that is, a dynamic continuous process of negotiation where entrepreneurs’ legitimation is produced and maintained. Entrepreneurs negotiate power dimensions drawing on strategies such as bounded disclosure where they manage the information they divulge. However the findings from this study also demonstrate that tensions and complexities can emerge resulting in lapses in performance. These are explained through issues of ambivalence towards emotion management, ambiguity over social boundaries and inadequacy in managing information flow.

Dans le domaine des relations industrielles, on a vu apparaître, ces dernières années, différents changements au niveau des relations du travail, notamment en matière de négociation collective. En effet, de nouvelles formes de négociation ont vu le jour en réponse aux changements qui se sont produits sur le marché du travail. De façon plus précise, les théoriciens se sont penchés, d’une part, sur des méthodes de négociation moins conflictuelles et les acteurs concernés par la négociation collective ont su les mettre en pratique, d’autre part. Cependant, bien que certains aient tenté de substituer ces méthodes plus coopératives à la négociation traditionnelle de façon intégrale, les théoriciens et praticiens se sont aperçus qu’il était plutôt difficile de les adopter à l’état pur et ce, de façon alternative à la négociation traditionnelle. Afin d’optimiser les gains mutuels lors de la négociation d’une entente, les négociateurs vont plutôt opter pour un usage combiné des méthodes plus traditionnelles et des nouvelles formes dites plus coopératives; on parle alors de négociation mixte. Toutefois, peu d’études portant sur la négociation mixte ont été conduites. Nous croyons néanmoins que cette forme de négociation est plus appropriée, notamment en raison de la nature des enjeux traités à l’occasion d’une négociation collective. S’insérant dans ce contexte, l’objet de notre recherche est donc l’étude, par l’entremise d’un cas particulier, de la négociation mixte. De façon plus précise, nous cherchons à évaluer la méthode de négociation adoptée lors de la négociation collective ayant eu lieu entre le Centre de la petite enfance Pomme Soleil (CPE) et le Syndicat des intervenantes en petite enfance de Montréal (SIPEM) – CSQ en 2005. Afin d’y parvenir, nous avons vérifié les propositions et hypothèses suivantes : (1) la nature du climat des négociations précédentes a une influence sur la méthode de négociation de type mixte adoptée par les parties au cours de la négociation de la convention collective, (2) la nature du climat des relations industrielles a une influence sur la méthode de négociation de type mixte adoptée par les parties au cours de la négociation de la convention collective, (3) le passage du temps a un effet de transition sur la méthode de négociation de type mixte qui manifeste une dominante intégrative dans les étapes initiales de la négociation et une dominante distributive dans les étapes finales, (4) les négociateurs ayant reçu une formation à la négociation basée sur la résolution de problèmes ou basée sur les intérêts adoptent une méthode de négociation de type mixte à dominante intégrative, (5) l’expérience des négociateurs patronal et syndical a une influence sur la méthode de négociation de type mixte adoptée par les parties au cours de la négociation de la convention collective, (6) la stratégie de négociation initiale adoptée par les parties a une influence sur la méthode de négociation de type mixte au cours de la négociation de la convention collective et (7) la négociation des clauses à incidence pécuniaire donne lieu à une méthode de négociation de type mixte à dominante distributive. Grâce aux résultats que nous avons recueillis par l’entremise de l’observation de la négociation collective entre le CPE Pomme Soleil et le SIPEM, mais principalement par le biais des entrevues, nous sommes en mesure d’affirmer que, conformément à notre question de recherche, la négociation fut mixte, à dominante intégrative. Cependant, la question salariale, bien qu’elle ne fut pas abordée à la table de négociation mais avec le gouvernement provincial, prit une tangente distributive. En ce sens, nous pouvons dire que la négociation fut mixte et ce, de façon séquentielle. / In the field of industrial relations, we saw appearing, these last years, various changes in work relations, particularly in collective bargaining. Indeed, new forms of negotiation were born in answer to the changes which occurred in the labor market. In a more precise way, the theorists bent, on one hand, over less conflicting methods of negotiation and the actors concerned by the collective bargaining knew how to put them into practice, on the other hand. However, although some tried to substitute these more cooperative methods for the traditional negotiation, the theorists and the practitioners noticed that it was rather difficult to adopt them in a pure state, in an alternative way to the traditional negotiation. To optimize the mutual earnings during the negotiation of an agreement, the negotiators will rather opt for a combined use of the more traditional methods and the new cooperative forms; we speak then about mixed negotiation. However, few studies concerning the mixed negotiation were driven. We believe nevertheless that this kind of negotiation is more suited, in particular because of the nature of the stakes handled on the occasion of a collective bargaining. Fitting into this context, the object of our research is thus the study, by the observation of a particular case, of mixed negotiation. In a more precise way, we try to evaluate the method of negotiation adopted during the collective bargaining that took place between the Centre de la petite enfance Pomme Soleil (CPE) and the Syndicat des intervenantes en petite enfance de Montréal (SIPEM) – CSQ in 2005. To reach there, we verified the propositions and the following hypotheses: (1) the nature of the climate of the previous negotiations has an influence on the method of mixed negotiation adopted by the parties during the negotiation of the collective agreement, (2) the nature of the climate of the industrial relations has an influence on the method of negotiation of mixed type adopted by the parties during the negotiation of the collective agreement, (3) the passage of time has an effect of transition on the method of mixed negotiation which shows an integrative dominant in the initial stages of the negotiation and a distributive dominant in the final stages, (4) the negotiators who have received a training in interest-based negotiation adopt a method of mixed negotiation with an integrative dominant, (5) the experience of the employer’s and labor-union’s negotiators has an influence on the method of mixed negotiation adopted by the parties during the negotiation of the collective agreement, (6) the initial strategy of negotiation adopted by the parties has an influence on the method of mixed negotiation during the negotiation of the collective agreement and (7) the negotiation of clauses with pecuniary incidence give place to a method of mixed negotiation with distributive dominant. Thanks to the results which we collected by the intervention of the observation of the collective bargaining between the CPE Pomme Soleil and the SIPEM, but mainly by means of the interviews, we are capable of asserting that, according to our research question, the negotiation was mixed, with an integrative dominant. However, the wage question, although it was not approached at the table of negotiation but with the provincial government, took a distributive tangent. In this way, we can say that the negotiation was mixed in a sequential way.

Ordinary Least Squares (OLS) regression analysis is applied to a cross-national data set to test two hypotheses concerning governments' hard-line response against terrorism: do hard-line responses cause more damage vis a vis event outcome and is the hard-line approach a deterrent? Six national factors are included in this analysis: economic development, economic growth rate, democratic development, leftist regime type, military regime type and British colonial legacy. Only the level of economic development, economic growth rate and leftist regime type demonstrated statistically significant relationships with the dependent variable "event frequency." Government response strength demonstrated a strong statistically significant relationship with event outcome, however, its relationship with event frequency was statistically insignificant.
