Purpose The purpose of the thesis is to contribute toward establishing the relationship between the concepts of sustainability reporting, sustainability performance, and sustainability reputation.This will be done by investigating the causal relationships between these concepts and whether those relationships are negative or positive. Methodology The study is based on a positivistic philosophy with a deductive approach. By using a quantitative method and a longitudinal design, the causal influences from the independent variables in 2019 to the dependent variables in 2020 could be investigated in a sample of 99 companies. This was done by 297 firm-year observations for measuring sustainability performance, and by 198 firm-year observations for measuring sustainability reputation and sustainability reporting respectively. Secondary data from the agency SB Insight together with primary data from companies’ sustainability reports and annual reports were mainly tested by a multiple linear regression model. Findings The findings show that sustainability reporting is negatively affected by sustainability performance and indicate that the causality is unilateral from sustainability performance tosustainability reporting. Sustainability reputation is positively affected by sustainability reporting, but sustainability reporting is in addition positively affected by sustainability reputation, indicating a bidirectional relationship where the causality remains unsolved. The findings show no significant association between sustainability performance and sustainability reputation. Furthermore, the thesis suggests a new concept to the research field, namely the reporting-reputation-spiral. Theoretical Perspectives The study analyzed the results through the legitimacy theory, the stakeholder theory, the voluntary disclosure theory, and the signal theory

Detta är en uppsats som analyserar tre nedslag tagna ur svensk designhistoria. Bakgrunden ligger i Sveriges varumärke, nation brand. Materialet utgörs av marknadsföring från Stockholmsutställningen 1930, reklambilder från IKEA under 1980-talet och ompositioneringen av varumärket “Sweden” 2014. Teorin bygger på semiotik och vad nation brand och national reputation är och gör. Metoden utgår från semiotik och analysen görs utefter en semiotisk analysmetod av det bildmaterial som valts ut från dessa tre nedslag i svensk designhistoria. Då detta är en undersökning inom ett fält där personliga tolkningar och bakgrund spelar stor roll i hur materialet analyseras är det svårt att hitta ett definitivt svar på den eventuella forskningsfrågan - resultat blir istället en diskussion om samspelet mellan nation och analysmaterialet, hur nationen påverkat dessa och hur de i sin tur påverkat nationen och dess varumärke.

Les réseaux sociaux ont connu une évolution dramatique et ont été utilisés comme des moyens pour exercer plusieurs activités. En fait, via les réseaux sociaux, les utilisateurs peuvent découvrir, gérer et partager leurs expériences et avis en ligne. Cependant, la nature ouverte et décentralisée des réseaux sociaux les rend vulnérables à l'apparition des utilisateurs malveillants. Par conséquent, les utilisateurs éventuels peuvent faire face à plusieurs de problèmes liés à la confiance. Ainsi, une évaluation de confiance effective et efficace est très importante pour la prise de décisions par ces utilisateurs. En effet, elle leur fournit des informations précieuses leur permettant de faire la différence entre ceux dignes et indignes de confiance. Cette thèse a pour but de fournir des méthodes de gestion de confiance et de réputation des utilisateurs des réseaux sociaux efficaces et qui peuvent être présentées par les quatre contributions suivantes. La première contribution présente une complexe extraction des contextes et des intérêts des utilisateurs, où les informations contextuelles sociales complexes sont prises en compte, reflétant mieux les réseaux sociaux. De plus, nous proposons un enrichissement de l'ontologie Dbpedia par des concepts de folksonomies.Ensuite, nous proposons une approche de gestion de la confiance, intitulée IRIS, permettant la génération du réseau de confiance et le calcul de la confiance directe. Cette approche considère les activités sociales des utilisateurs incluant leurs relations sociales, préférences et interactions.La troisième contribution de cette thèse est la gestion de transitivité de confiance dans les réseaux sociaux. En fait, c'est nécessaire et significatif d'évaluer la confiance entre deux participants n’ayant pas des interactions directes. Nous proposons ainsi, un modèle d'inférence de confiance, appelé TISON, pour évaluer la confiance indirecte dans les réseaux sociaux.La quatrième contribution de cette thèse consiste à gérer la réputation des utilisateurs des réseaux sociaux. Pour ce faire, nous proposons deux nouveaux algorithmes. Nous présentons un nouvel algorithme exclusif pour la classification des utilisateurs basés sur leurs réputations, appelé le RePC. De plus, nous proposons un deuxième algorithme, FCR, qui présente une extension floue de RePC. Pour les approches proposées, nous avons conduits différentes expérimentations sur des ensembles de données réels ou aléatoires. Les résultats expérimentaux ont démontré que nos algorithmes proposés produisent de meilleurs résultats, en termes de qualité des résultats livrés et d’efficacité, par rapport à différentes approches introduites dans littérature / Online Social Networks (OSNs) have known a dramatic increase and they have been used as means for a rich variety of activities. In fact, within OSNs, usersare able to discover, extend, manage, and leverage their experiences and opinionsonline. However, the open and decentralized nature of the OSNs makes themvulnerable to the appearance of malicious users. Therefore, prospective users facemany problems related to trust. Thus, effective and efficient trust evaluation isvery crucial for users’ decision-making. It provides valuable information to OSNsusers, enabling them to make difference between trustworthy and untrustworthyones. This thesis aims to provide effective and efficient trust and reputationmanagement methods to evaluate trust and reputation of OSNs users, which canbe divided into the following four contributions.The first contribution presents a complex trust-oriented users’ contexts andinterests extraction, where the complex social contextual information is taken intoaccount in modelling, better reflecting the social networks in reality. In addition,we propose an enrichment of the Dbpedia ontology from conceptualizations offolksonomies.We second propose the IRIS (Interactions, Relationship types and Interest Similarity)trust management approach allowing the generation of the trust networkand the computation of direct trust. This model considers social activities of usersincluding their social relationships, preferences and interactions. The intentionhere is to form a solid basis for the reputation and indirect trust models.The third contribution of this thesis is trust inference in OSNs. In fact, it isnecessary and significant to evaluate the trust between two participants whomhave not direct interactions. We propose a trust inference model called TISON(Trust Inference in Social Networks) to evaluate Trust Inference within OSNs.The fourth contribution of this thesis consists on the reputation managementin OSNs. To manage reputation, we proposed two new algorithms. We introducea new exclusive algorithm for clustering users based on reputation, called RepC,based on trust network. In addition, we propose a second algorithm, FCR, whichis a fuzzy extension of RepC.For the proposed approaches, extensive experiments have been conducted onreal or random datasets. The experimental results have demonstrated that ourproposed algorithms generate better results, in terms of the utility of delivered results and efficiency, than do the pioneering approaches of the literature

Sustainability is a highly discussed subject in today’s society. One industry that is facing big challenges when it comes to its environmental effect is the fashion industry. The pressure to live up to the society’s norms regarding sustainability can lead to greenwashing. Greenwashing arises when a company's positive communication regarding their sustainability does not match with their actual environmental impact. When it comes to how companies want to portrait themselves and communicate they can choose to focus on either creating a good reputation or be legitimate. These two ways of communicating can end up in conflict since it is important to differentiate from competitors but also show that you follow expected norms. This essay’s purpose has been to investigate how two of the world’s highest valued fashion companies, H&M Group and Inditex, focus on reputation or legitimacy for their sustainability communication. The essay shows that H&M Group and Inditex are very similar in their use of both reputation and legitimacy for their sustainability communication. The study shows that both companies focus slightly more on creating a better reputation than legitimacy though. The essay also shows that both companies possibly could be using greenwashing to strengthen their reputation and legitimacy. / I dagens samhälle är hållbarhet ett högst aktuellt ämne. En bransch som står inför stora utmaningar när det gäller dess påverkan på miljön är modebranschen. Pressen att leva upp till omgivningens normer kring hållbarhet kan leda till greenwashing. Greenwashing uppstår när företags positiva kommunikation kring sitt miljöarbete inte stämmer överens med det faktiska miljöarbetet. När det kommer till hur företag vill porträttera sig och kommunicera kan de fokusera på att antingen skapa ett gott anseende eller vara legitima. Dessa två sätt att kommunicera på kan hamna i konflikt då det är viktigt att vara konkurrenskraftig men också visa att man följer förväntade normer. Denna uppsats syfte har därför varit att undersöka huruvida två av de högst värderade modeföretagen, H&M Group och Inditex, fokuserar på anseende eller legitimitet i sin hållbarhetskommunikation. Uppsatsen visar att H&M Group och Inditex är mycket lika i sin användning av både anseende och legitimitet i sin hållbarhetskommunikation. Studien visar dock att företagen fokuserar aningen mer på att öka sitt anseende än sin legitimitet. Uppsatsen visar också att båda företagen möjligtvis använder sig av greenwashing för att stärka sitt anseende och legitimitet.

Die vorliegende Arbeit setzt sich mit den Steuerungsanforderungen in einem Wertschöpfungsnetzwerk eines Service-Integrators auseinander. Hierzu wird zunächst das Geschäftsmodell des Service-Integrators abgegrenzt und eine Einordnung in eine Typologie von Netzwerkunternehmen vorgenommen. Anschließend erfolgt eine Untersuchung der Steuerungsbedarfe aus organisationstheoretischer Sicht und ein Abgleich mit entsprechenden Instrumenten von bestehenden Arbeiten aus dem Bereich der Steuerung von Unternehmensnetzwerken. Es wird dabei gezeigt, dass die Konzepte Vertrauen und Reputation nicht inkludiert sind, woraufhin ein leistungsbasiertes Verständnis von Reputation, auf Basis von Vertragsverletzungen, aufgebaut wird, nachdem ein entsprechendes Verständnis von Vertrauen und Reputation aus betriebswirtschaftlicher Literatur abgeleitet wurde. Dieses Instrument wird, im Rahmen eines auf Basis von SCOR entwickelten Kennzahlenmodells, als Instrument zur Steuerung von Netzwerken von Service Integratoren aufgebaut. Abschließend erfolgt eine prototypische Umsetzung und damit die Evaluierung der Machbarkeit und Gültigkeit unter den getroffenen Annahmen, dieses Instruments im Rahmen eines Instruments für einen logistischen Service-Integrator. Im Zuge der Arbeit wird gezeigt, dass die Steuerung des Netzwerks eines Service-Integrators besondere Anforderungen an eine Netzwerksteuerung stellt, welche durch ein erweitertes, leistungsbasiertes Instrument, auf Basis der Verhaltenshistorie erfüllt werden können.

The goal of this master's thesis is to design and implement agent system for dealing with sportsmen. It will be possible to apply trust and reputation principles on this system. This system is implemented in Jason agent language. Agents there posing as sports club managers. The main target of these managers is to have the maximal profit. The environment of agents is changing by playing the matches between the teams. Players quality evalution follows the played matches. Based on played matches, managers can evaluate the worth of each player and trade them in order to achieve the maximal possible profit. Untrustworthy agents take a place in this system. These agents overvalue their players using inccorect behavior. The experiments will be made within this masters's thesis in order to compare gain of apllication trust and reputation principles.

Aim: The study aims to explore the process of service recovery, its transformation into a marketing tool and identifying the outcomes of the tool to the organizations. Methodology: The research employed a qualitative methodology with an inductive approach. Data collection was carried out via semi-structured interviews with participants from four organizations in Stockholm City. The analysis involved the use of questions based on the main concepts derived from the literature and manual coding scheme to identify new themes. Findings & Conclusion: Service recovery is a powerful marketing tool that can benefit organizations in various ways. By implementing effective strategies such as employee training, transparency, multiple service recovery options, and process improvement, organizations can turn service failures into opportunities. The outcomes of using service recovery as a marketing tool include customer retention and repeat purchases, positive word-of-mouth marketing, confidence and trust, building customer relationships, competitive advantage, and business growth and sustainability. The findings of the study highlight the critical importance of service recovery in marketing for customer retention and acquisition. Limitations and recommendations for further research: While this study provides valuable insights into how organizations can use service recovery as a marketing tool, further research is needed to understand its impact from a customer’s perspective and to broaden the scope of industries and geographic locations studied. Further research is also suggested to compare the performance of organizations that prioritize service recovery in marketing with those that don’t and to conduct a comparative analysis with other marketing tools. Also, exploring additional theories and concepts could provide a more comprehensive understanding of the topic.
