The great technological development under the last decade has given the organizations new possibilities to market them self. Mobiles phones, smart phones and the new ultraportable laptops which make it possible to for organizations to send advertisement consumers 24/7. This has led to a steady increase in research during the last decade concerning mobile advertising. The research has mainly been focused on how problems with negative attitudes towards mobile advertising can be changed in to positive ones. Mobile advertising suffers from the same problems as several recently introduced marketing channels have done e.g. ecommerce like trust, privacy and risks. Beside the negative aspects, mobile advertising research has focused on identifying factors that will stimuli consumer willingness to receive mobile advertisement and identified a target group for this marketing channel. The target group has been identified to be young adults in the ages of 18-35. We will in our research´focus on this area about this different problem factors with mobile advertising and try to find which factors that are most important and affecting consumers attitudes towards mobile advertising we further want to develop ideas for how marketers can construct mobile advertising so that consumers accept it as a marketing channels. To examine this, quantitative method was used with a sample of 198 15-19 year old high school students in Umea responding to our survey. The sample was chosen because we believe that this age group will be the ones that are the target for mobile advertisers when the business have picked up more speed in a few years time. This group has also been identified by other researchers as an interesting segment to investigate. We have a positivistic approach to the study and therefore we have worked out six hypotheses that will be tested and then compared with our theoretical framework using a deductive method. Our findings confirmed five out of six hypotheses. Consumers are negatively affected by factors as risk, lack of trust and privacy. The attitudes can change towards more positive ones if consumers perceive the advertisement relevant, entertaining, valuable functional and if they get some form of incentives for receiving advertisement. The hypothesis that we were not able to confirm concerned the consumer factors where only three of five factors were significant in our tests.

It is increasingly common that Swedish companies get acquired by foreign firms. An acquisition will have more evident changes in the acquired firm. The organisational structure will be affected which implies that people in different levels of the organisation experience the changes differently. Middle managers are believed to have an exposed role in organisational changes as they are in between top management and employees. In order to reach a successful integration in the postacquisition process employee trust in management is seen as a vital part. The area of middle managers in acquisitions and how individuals experience the post-acquisition process are subjects where more research is needed. The purpose of this thesis is to investigate the post-acquisition process in the acquired firm, focusing on how the acquisition has been experienced among middle managers and their employees. The method chosen for thesis is qualitative and the information has been collected by using semi-standardised interviews as well as questionnaires. The study was limited to one company where seven middle managers and the human resource manager were interviewed. Also 32 employees participated in the study by answering the questionnaires. We can conclude that the middle managers did not show resistance to changes unless it would be unfavourable for the company. We could also see indications that internally advanced middle managers can be related to an advantageous atmosphere of communicating trust. It was also concluded that middle managers are a vital link in terms of conveying information throughout the post-acquisition process.

This study investigates if a divorce affects the attitudes and trust between parents and adolescents. Participants were 986 adolescents and their parents, taken from a Swedish longitudinal study, the “10 to 18” study. This study used 28 measures of parent-adolescent relationships, which created three areas: warmth, closeness and conflicts between parents and adolescents. The adolescents were divided into three groups, and one-way ANOVAs were made to test differences. The results showed that a divorce affects the father-adolescent relationship more than the mother-adolescent relationship. They also showed that the attitudes and the trust between parents and adolescents were affected by a divorce. / Den här studien undersökte om en skilsmässa kan påverka attityderna och tilliten mellan föräldrar och ungdomar. Deltagarna bestod av 986 ungdomar och deras föräldrar, från en svensk longitudinell studie, ”10 till 18” studien. Den här studien använde 28 mått som mätte relationen mellan föräldrarna och ungdomarna, dessa skapade tre områden: värme, närhet och konflikter mellan föräldrarna och ungdomarna. Ungdomarna delades in i tre grupper och envägs ANOVA genomfördes för att testa skillnaderna. Resultaten visade att relationen mellan papporna och ungdomarna påverkades mer än relationen mellan mammorna och ungdomarna. Resultaten visade också att attityderna och tilliten mellan föräldrarna och ungdomarna påverkades av skilsmässan.

This study aims at investigating the spousal relationships of persons who have been diagnosed with dementia and are living in a nursing home. Eight spouses’ descriptions of their relationship, spousal interaction and the relationship´s impact on the spouse´s life were captured through qualitative interviews. The results show three main types of interaction patterns: one of spousal joy and happiness; a combination of both happiness and sadness; and a pattern of no positive reactions. The strength of the relationship was based on the analysis of trust, intimacy and commitment to the relationship. The spouses who described their relationships as most meaningful were strongly committed and expressed trust. Intimacy was generally low. When asked about plans for the future the results showed that some spouses included the person with dementia, while others excluded. This combined with the view of how the dementia disease affects the person, shows that in meaningful interactions the spouse separated the disease from the person. The relationships where interactions were more problematic showed that this separation did not occur in the same way.

This dissertation examines the role of extreme media (i.e. political talk radio and cable news opinion shows) on the political attitudes of viewers and listeners. I investigate whether extreme media has both positive and negative externalities for democratic citizenship. Specifically, I use laboratory experiments, national survey data, and qualitative interviews to test the impact of extreme media on viewers' political knowledge, trust in government, efficacy, and political tolerance. I use laboratory experiments in controlled settings to uncover the impact of viewership on political knowledge, trust in government, and efficacy. I confirm these lab findings with the national survey data, by using propensity score matching and ordered probit models to demonstrate that exposure to extreme media produces political knowledge and efficacy, but decreases trust in government. I further use process tracing to ascertain the motivations individuals use to choose to view extreme media. Finally, through subject interviews conducted as part of the self-selection portion via a 1 x 3 self-selection experiment, I find subjects seek out entertaining media specifically from ideologically similar outlets. This project advances the media and politics literature by demonstrating the capacity for extreme media to alter political behavior, attitudes, and information processing.

In the field of multiagent systems, trust and reputation systems are intended to assist agents in finding trustworthy partners with whom to interact. Earlier work of ours identified in theory a number of security vulnerabilities in trust and reputation systems, weaknesses that might be exploited by malicious agents to bypass the protections offered by such systems. In this work, we begin by developing the TREET testbed, a simulation platform that allows for extensive evaluation and flexible experimentation with trust and reputation technologies. We use this testbed to experimentally validate the practicality and gravity of attacks against vulnerabilities. Of particular interest are attacks that are collusive in nature: groups of agents (coalitions) working together to improve their expected rewards. But the issue of coalitions is not unique to trust and reputation; rather, it cuts across a range of fields in multiagent systems and beyond. In some scenarios, coalitions may be unwanted or forbidden; in others they may be benign or even desirable. In this document, we propose a method for detecting coalitions and identifying coalition members, a capability that is likely to be valuable in many of the diverse fields where coalitions may be of interest. Our method makes use of clustering in benefit space (a high-dimensional space reflecting how agents benefit others in the system) in order to identify groups of agents who benefit similar sets of agents. A statistical technique is then used to identify which clusters contain coalitions. Experimentation using the TREET platform verifies the effectiveness of this approach. A series of enhancements to our method are also introduced, which improve the accuracy and robustness of the algorithm. To demonstrate how this broadly-applicable tool can be used to address domain-specific problems, we focus again on trust and reputation systems. We show how, by incorporating our work into one such system (the existing Beta Reputation System), we can provide resistance to collusion. We conclude with a detailed discussion of the value of our work for a wide range of environments, including a variety of multiagent systems and real-world settings.

Purpose – The purpose of this research was to explain the determiners that influence customer loyalty in rural grocery stores with a comparison of Sweden and Spain. Design/methodology/approach – This is a quantitative research using a multi-cross sectional design with an explanatory approach. The data was collected with a questionnaire survey that was distributed using a face-to-face and online method. Findings – The findings of the research revealed significant support for customer perceived value, satisfaction, trust and commitment to influence customer loyalty. The research also confirms that there are differences in customer loyalty regarding rural grocery stores between Sweden and Spain. Research limitations/implications – This thesis extend previous research by testing an adapted conceptual model of customer loyalty in a context of rural grocery stores and explain the determiners of customer loyalty in Sweden and Spain. The limitations of the research are discussed and directions for future research areas are suggested. Practical implications – The study provides rural retailers with suggestions for marketing strategies related to the determiners (i.e. customer perceived value, satisfaction, trust and commitment) that might influence customer loyalty and attract the rural customers. Originality/value – This research adds to the current stream of rural research by investigating how customer loyalty can enhance profitability. This research has originality since it makes a comparison of two countries, which can be of great interest and inspiration for how to maintain and develop rural grocery stores. Lastly, the research is significant as it provides implications to rural retailers as well as Provincial Governments.

In 2004 as many as 25% of teachers in Sweden, Denmark, and England were willing to leave their profession immediately; in the United States much effort has been invested in studying why teachers leave the profession. In this paper, four teachers who left the profession were interviewed from within the life-story tradition. In the narratives, which were rendered in a poetic style during the analysis, colleagues were mentioned both positively and negatively. The theme of having colleagues, and especially trust or mistrust between colleagues, was thus explored. The existence or non-existence of lateral trust between teachers can be connected both to school development and to student learning outcomes.

The e-commerce is growing among customers and also the companies are more active online. One industry that focuses on customer experience is the online fashion industry. In Sweden, the half of the population has at some time shopped clothes and footwear online. However, for companies to compete against others and to survive in this crowded market, it is important to create e-loyalty. Thereby, the purpose for this study was to evaluate the antecedents of e-loyalty in the online fashion industry. E-loyalty is according to famous researchers one important ingredient to succeed online and stay profitable. Other important ingredients for e-loyalty are e-satisfaction, e-trust and e-service quality. All of these factors have been investigated and evaluate in which degree they affect e-loyalty.   In this master thesis, assessed 212 respondents included in the population. The findings have been tested by following statistical analysis; reliability test, exploratory factor analysis, correlation analysis and regression analysis. The result showed that e-satisfaction is the main driver for e-loyalty in the online fashion industry. Thereby, a manager should put main focus in what affect e-satisfaction to increase in e-loyalty in this industry. However, the result from the investigation also stressed an interesting factor, namely responsiveness. This factor was shown to have a significant influence on e-loyalty but also on e-satisfaction and e-trust.

In order to succeed, it is imperative that all e-commerce systems include an effective and reliable trust and reputation modeling system. This is particularly true of decentralized e-commerce systems in which autonomous software engage in commercial transactions. Many researchers have sought to overcome the complexities of modeling a subjective, human concept like trust, resulting in several trust and reputation models. While these models each present a unique offering and solution to the problem, several issues persist. Most of the models require direct experience in the e-commerce system in order to make effective trust decisions. This leaves new agents and agents who only casually use the e-commerce system vulnerable. Additionally, the reputation ratings of agents who are relatively new to the system are often indistinguishable from scores for poorly performing agents. Finally, more tactics to defend against agents who exploit the characteristics of the open, distributed system for their own malicious needs are required. To address these issues, a new metric is devised and presented: seniority. Based on agent age and activity level within the e-commerce system, seniority provides a means of judging the credibility of other agents with little or no prior experience in the system. As the results of experimental analysis reveals, employing a reputation model that uses seniority provides considerable value to agents who are new agents, casual buyer agents and all other purchasing agents in the e-commerce system. This new metric therefore offers a significant contribution toward the development of enhanced and new trust and reputation models for deployment in real-world distributed e-commerce environments.
