Instagram är ett populärt socialt nätverk bland unga människor mellan 18-25 år. Psykiska pressen på individen att vara en del av sociala-medier och hålla sig uppdaterad kan betraktas som centralt i unga människors upplevelser av sociala medie-plattformen Instagram. Med sociala mediers frammarsch har en ny sorts kommersiell förebild skapats denna har fått benämningen Influencers. Studiens syfte ämnar besvara följande frågeställningar: Hur upplever unga kvinnor fenomenet Instagram och Instagram-Influencers? Hur påverkas unga kvinnors identitet av Influencers på det sociala mediet Instagram? Hur upplever unga kvinnor att deras identitet gestaltar sig, i de fall påverkan sker? En kvalitativ metod/ansats har använts i form av semistrukturerade intervjuer med sex unga kvinnor i åldern 18-25. Det insamlade materialet har analyserats med tematisk analys utifrån en induktiv ansats. Studien tar fasta på: respondenternas tankar, upplevelser och känslor kring den egna subjektiva erfarenheten och dess mening i deras livsvärld. Resultatet knyts an till tre huvudteman; Instagrams betydelse, Att vara en Influencer, Influencers och deras påverkan på sina följare.Dessutom behandlas underkategorin: Identitet online respektive identitet offline. Studiens resultat visar att respondenterna upplever Instagram som både betydelsefull media och som en “jämförelse-applikation” med negativ inverkan. Studien visar även hur den negativa påverkan i högre grad dominerar upplevelsevärlden. Det finns en tydlig koppling mellan en ökad digital interaktion och upplevelsen av social jämförelse och påverkan på ens identitet. Respondenterna anser att Influencers skapar en vilseledande bild av verkligheten och censurerar sådant som är mindre smickrande. Följarna får en filtrerad uppfattning som syftar till att förstärka det budskap man vill uppmärksamma. Respondenterna själva uppvisar konstruerade bilder av lycka, men i verkligheten – offline- kan istället känslor av ensamhet och ledsamhet finnas. Diskussionen tar upp den tydliga kopplingen mellan en ökad digital interaktion och känslan av social jämförelse, behov av konformitet och roll-imiterande beteende. / For young adult’s age 18-25 years, Instagram is a popular social network. With the expansion of social media, a new kind of commercial role- model has been created, the so- called Influencers. Based on the understanding and interpretation of previous research, this study will look into what impact the social network phenomena Instagram-Influencers have on young girls’ self-perception and identity. The purpose of this study is to answer the following questions: How do young women experience the social network Instagram and its Influencers? How is the identity of young women affected by the Influencers on the social media Instagram? In what way do young women experience that their identity is being shaped, in those cases it has an impact? To study this, qualitative interviews are used and conducted with six different active female users, between ages 18-25. The collected data were analyzed with a thematic inductive approach. The result is linked to three main themes; Instagram's importance, being an Influencer, Influencers and their impact on their followers, as well as the subcategory: Identity online and identity offline. In my analyzation, the conclusion is, that there is a clear link between an increased digital interaction and social comparison, and their effect on identity and self-perception. The respondents believe that the Influencers display a misleading view of reality. The followers get the impression that the content is filtered and only highlights flattering topics, and that the purpose with this is to enforce and emphasize the value of the Influencers’ statements. Similarly, the respondents themselves are affected to construct images of happiness, but in reality – offline- the feeling of loneliness and sadness occurs. The end discussion addresses the clear link between increased digital interactions and the sense of social comparison, the need for conformity and role-limiting behavior.

Considerando-se a importância das relações sociais e da influência interpessoal no comportamento dos indivíduos de baixa renda, este estudo apresenta como objetivo identificar e analisar os grupos de referência valorizados pelas consumidoras de baixa renda em seu processo de decisão de compra. Para a coleta de dados, utilizou-se uma abordagem multimétodo fundamentada, primeiro, em entrevistas em profundidade com 12 mulheres e, depois, na técnica de Análise Conjunta com uma amostra de 53 entrevistadas pertencentes a esse segmento. Devido à crise econômica vivida atualmente, mostrou-se necessário delimitar o contexto da pesquisa a um bem que permanecesse atrativo nessas circunstâncias: o batom. Trata-se de uma categoria de produto de alto envolvimento, capaz de representar o segmento de cosméticos como um todo, associando-se à autoestima, à sensação de bem-estar e ao reconhecimento social. Os resultados obtidos demonstraram que as consumidoras de baixa renda valorizam a presença de diferentes grupos de referência em seu processo de decisão. Especificamente, identificaram-se dois grupos de respondentes com preferências distintas quanto aos grupos de referência. Diante disso, ressalta-se que as principais contribuições desta pesquisa foram a observação de perfis diferentes dentro do segmento de baixa renda, o desenvolvimento do conhecimento sobre o processo de decisão de compra dessas mulheres e a identificação de apelos de grupos de referência que as empresas podem usar para atrair consumidoras de baixa renda. / Considering the importance of social relations and interpersonal influence on the behavior of low-income individuals, this study aims to identify and analyze the reference groups valued by low-income female consumers in their decision-making process. A multimethod approach was employed. First, the data were collected through in-depth interviews with 12 low-income women. Subsequently, a conjoint analysis technique was applied with a sample of 53 female interviewees belonging to this segment. Due to the current economic crisis, it was necessary to delimit the research context to a product that remained attractive in these circumstances: lipstick. It is a high involvement product category, capable of representing the segment of cosmetics as a whole, being related to self-esteem, a sense of well-being and recognition. Results showed that low-income female consumers value the presence of different reference groups in their decision-making process. Specifically, it was possible to identify two groups of respondents with distinct preferences regarding the reference groups. Therefore, the main contributions of this research were the observation of different profiles within the low-income segment, the development of knowledge about the decision-making process of these women, and the identification of reference group appeals that companies can use to attract low-income female consumers.

Notre recherche porte sur le rôle de la crédibilité des offres dans les sites d’e-commerce et les facteurs qui la déterminent. 294 personnes ont été interrogées à exprimer leur perception sur la crédibilité des offres de livres qui ont été composées en variant la source et les signes de leur réputation. La recherche s’inscrit dans une approche quasi-expérimentale qui vise à mesurer l’impact de ces facteurs sur la crédibilité perçue mais aussi à mesurer l’influence de cette dernière sur l’intérêt accordé à l’offre et en conséquence sur l’intention d’achat. Les analyses sont faites en se basant sur un modèle d’équation structurelle (SEM). Les résultats témoignent le rôle pivot de la crédibilité qui médiatise l’effet des signaux de la qualité de l’offre mis sur l’intérêt qu’elle soulève. Cet intérêt, à son tour, convoie l’impact de la crédibilité sur l’intention d’achat. Dans ses relations de cause, la crédibilité reconnaît ces signaux comme ses déterminants importants dont les poids sont de même ampleur et dont les effets sont additifs. Nous trouvons également l’effet significatif de la confiance dans la source ainsi que l’intérêt à la catégorie sur la crédibilité. L’effet de la confiance est positif et remarquable tandis que celui de l’intérêt à la catégorie reste négatif. Enfin, ces résultats nous permettent de conclure l’importance de la crédibilité : soigner la crédibilité de l’offre est le chemin au renforcement de l’intérêt du consommateur ainsi qu’aux performances des ventes. / Our research examines the role of online offers credibility in the customer judgment process and its determinants. 294 persons were requested to express their perception of online book offers credibility which were composed varying on their source and also on a number of reputation signals. This quasi-experiment aims for measuring impact of these factors on offer credibility but also for investigating influence of this one on consumer interest in offer and consequently on his purchase intention. Statistical analysis bases on a SEM model. The most important research finding shows that credibility mediates effects of reputation signals on consumer interest in offer. This element of interest, in turn, executes mediating effect on the causal relationship between credibility and purchase intention. Other results indicate that all the 4 reputation signals are positively associated, at the same amplitude, with perceived offer credibility. These effects are additive, which suggests that multiply these signals must be essential way for improving credibility. We found otherwise that credibility is also affected by consumer trust on the source and his interest manifested on the product category. Effect of trust is positive and remarkable while interest in the category effect is negative, which reveals that people with better knowledge level may be more skeptic than others in judgment process. According to these results, our proposal on the importance of credibility element in e-commerce activities is clear: look after the offer credibility is the nexus of merchants selling performance.

However, there is still room for studies which analyze the influence that a user a exerts on another user e, based on the frequency of interactions from e dedicated to a in the social network. In the case of Twitter, three interactions are commonly used by users: the like, the mention and the retweet. This work assumes that a direct way of measuring the influence of a user a over another user e on Twitter is to observe the number of interactions of e with a over time. In this sense, a new concept called loyalty is proposed to define a specific and personalized type of influence, in which users, through their interactions, demonstrate preference by some peers in the social network (i.e., through the frequency of the interactions). Three aspects of loyalty were analyzed: i) intensity of interaction with the preferred user; ii) probability of interaction with users with whom there is loyalty, and iii) predictability of user interactions with their peers. Experiments done on a large sample of Twitter users reveal that the vast majority of users have loyalty to some user. In addition, the type of interaction and cultural aspects such as the written language used in the tweets differently affect the three aspects of fidelity considered. The paper also offers suggestions on how information derived from loyalty may be useful for future work related to influence on Twitter. / Análise da Fidelidade no Comportamento dos Usuários do Twitter– Um Estudo a Respeito da Influência Social com uma Visão Local Para Redes Sociais Online. A análise da influência de usuários sobre outros tem tido destaque em estudos envolvendo as redes sociais online, em especial a rede social Twitter. Entretanto, ainda há carência de trabalhos que analisem a influência que um usuário a tem sobre outro usuário e, com base na quantidade de interações que e tem com a na rede social. No caso do Twitter, três interações são comumente utilizadas pelos usuários: o curtir (ou gostar), o retweet e a menção. Este trabalho parte do princípio que uma forma direta de avaliar a influência que um usuário a tem sobre um usuário e no Twitter é observar o número de interações de e com a ao longo do tempo. Nesse sentido, propõe-se um novo conceito, denominado fidelidade, para definir um tipo específico e personalizado de influência, em que os usuários, por meio de suas interações, demonstram preferência (através da frequência de interações) por alguns de seus pares na rede social. Analisou-se três aspectos da fidelidade: i) intensidade de interação com o usuário preferido; ii) probabilidade de interação com usuários aos quais há fidelidade e iii) previsibilidade do usuário ao interagir com seus pares. Experimentos feitos em uma grande amostra de usuários, revelam que a grande maioria dos usuários têm fidelidade com algum outro usuário. Além disso, o tipo de interação e aspectos culturais como a língua escrita utilizada afetam de modo diverso os três aspectos de fidelidade considerados. O trabalho também apresenta sugestões de como as informações derivadas sobre a fidelidade podem ser úteis para trabalhos futuros relacionados à influência no Twitter.

O presente estudo investiga qual o efeito que a divulgação de empresas solidárias apoiadoras e da remuneração de dirigentes de Organizações Sem Fins Lucrativos (OSFL) possui na decisão sobre o volume de contribuição e na propensão de doar futuramente por parte do doador individual. O estudo é consubstanciado em pesquisas desenvolvidas por Balsam e Harris (2014) e de Galle e Walker (2013) que encontraram evidências de que doadores reduzem as contribuições subsequente à divulgação, por parte da OSFL, de alta remuneração do dirigente; e, em pesquisa desenvolvida no Brasil por IDIS e Gallup (2016), que relatam a falta de confiança como um dos principais motivos para que doadores deixem de contribuir para as OSFL. Este estudo pressupõe que, divulgar empresas solidárias apoiadoras da OSFL gera compliance, um dos principais elementos de influência social citado por Cialdini e Trost (1998) sobre o doador, levando-o a perceber a OSFL como monitorada e, com maior confiança de que a organização cumpre a missão social para a qual se destina, reduzindo o efeito adverso ocasionado da divulgação pela própria OSFL de valores elevados de remuneração do dirigente. O procedimento metodológico para coleta de dados ocorreu por meio de um experimento, com 140 participantes estudantes de pós-graduação lato sensu em Ciências Contábeis da Universidade Federal do Paraná. Encontraram-se evidências de que o disclosure voluntário pela OSFL de empresa solidária apoiadora possui efeito positivo significativo na propensão de contribuição futura do doador individual, assim como o disclosure da remuneração do dirigente e da empresa solidária apoiadora, de forma interativa, conduz à maior probabilidade de doação futura pelo doador individual. Esperava-se que a divulgação da empresa solidária apoiadora apenas, ou essa em conjunto com a informação de menor remuneração do dirigente gerassem maiores volumes de contribuições pelo doador, contudo, não foram obtidas evidências empíricas que suportem as referidas hipóteses. Os achados também não confirmaram a hipótese de que, divulgados maiores valores da remuneração do dirigente seriam reduzidos o volume de contribuição e a propensão de doação futura. Os resultados implicam que a divulgação da empresa solidária apoiadora pela OSFL suscita uma resposta por parte do doador em relação à probabilidade de doar futuramente em consonância à comunicação explícita da organização, neste caso a solicitação de doação, possivelmente ocorrendo o compliance como forma de influência social de direcionamento pela figura de autoridade legítima exercida pela empresa solidária apoiadora. Isto ocorre inclusive quando a divulgação é realizada em conjunto com a remuneração do dirigente, indicando a relevância do disclosure voluntário por parte das OSFL na captação de recursos. Desta forma, este estudo amplia os conhecimentos sobre o disclosure voluntário em OSFL, principalmente relacionado à divulgação da empresa solidária apoiadora como fonte de autoridade legítima e do efeito de compliance sobre o doador individual. / This study investigates the effect of disclosure of Influential Institutional Partners and senior management\'s compensation on individuals\' decisions to donate for non-profit organizations (NPOs). Prior research (Balsam & Harris, 2014; Galle & Walker, 2013) indicate that donors reduce donations after the disclosure of senior manager\'s high compensation by the NPOs, and in the Brazilian setting (IDIS & Gallup, 2016), lack of trust is one of the main reported reasons for donors to stop contributions for NPOs. Based on the literature on social influence, this study argues that the Influential Institutional Partner\'s disclosure increases the donors\' compliance with the NPOs (Cialdini & Trost, 1998). This behaviour should lead donors to conclude that the NPO is an entity under monitoring, and drive higher trust that the organization reaches the social mission for which it is intended, reducing the adverse effect caused by the disclosure of senior management\'s high compensation. The experimental is conducted with 140 graduate accounting students at the Federal University of Parana (UFPR). The results indicate that NPOs voluntary disclosure has a significant positive effect on the individual donors\' propensity of future donations, as does, interactively, the disclosure of senior management\' compensation and of the Influential Institutional Partners. However, no empirical evidence was found supporting the main or interactive effects of disclosure of Influential Institutional Partners and senior management\'s compensation on donors contribution\'s amount. Findings also did not confirm that disclosure of senior management\'s higher compensation result in lower propensity of future donations by individual donors. The results imply that the Influential Institutional Partner\'s disclosure by NPOs drives a response from donors with respect to the probability of making future donations in accordance with explicit communications by the organization, leading to the compliance as a form of social influence, exerted by the legitimate authority figure represented by the Influential Institutional Partner. This also happen when the disclosure is made in conjunction with senior management\'s compensation, indicating the relevance of the NPO\'s voluntary disclosure in fundraising. This study broadens the knowledge on voluntary disclosure by NPOs, in particular about the Influential Institutional Partner\' disclosure as a source of legitimate authority, and the effect of compliance on individual donors.

Abstract Organizations continuously strive to engage customers in the services development process. The social web facilitates this process by enabling novel channels for voluntary feedback-sharing and collaborative interaction through social media and technologically advanced environments. The component parts of these environments are information systems that are linked with social media and designed for large displays to support interactivity. The work performed during this research involved the design and assessment of operational software features for encouraging user engagement through publicly displayed information systems. Drawing upon socio-psychological theories and interconnecting them to the seven social influence design principles listed in the Persuasive Systems Design model, this dissertation examines the role of persuasive software features in altering human behavior with respect to engagement in feedback-sharing and collaborative interaction. The dissertation consists of five quantitative studies, including one Twitter survey (involving 403 respondents) and four experiments with publicly displayed Twitter-based systems (involving 284 users), that successively complement each other to address the main research question: How can social influence design principles persuade people to engage with publicly displayed systems that are integrated with social media? The results of these studies reveal interplay between the design principles and indicate that they have the capacity to improve the persuasiveness of information systems and predict the behavioral intentions of users to engage with such systems in the future. Based on these findings, a framework for studying socially influencing systems (SIS) is proposed. This framework is potentially instrumental in achieving a richer understanding of how to effectively harness social influence for enhanced user engagement through socio-technical environments and for the future development of persuasive information systems. / Tiivistelmä Organisaatioiden palvelukehityksen tavoitteena on sitouttaa ja innostaa asiakkaita. Sosiaalinen verkko edistää tätä prosessia tarjoamalla uusia väyliä niin vapaaehtoiselle palautteenjaolle kuin sosiaalisessa mediassa ja edistyneissä teknologisissa ympäristöissä tapahtuvalle interaktiiviselle yhteistyöllekin. Nämä ympäristöt koostuvat tietojärjestelmistä, jotka on yhdistetty sosiaaliseen mediaan, ja jotka on suunniteltu interaktiota edistäville suurille näytöille. Tässä tutkimuksessa on suunniteltu ja arvioitu ohjelmisto-ominaisuuksia, joiden tarkoitus on suostutella ja osallistuttaa julkisesti esilläolevien tietojärjestelmien ja näyttöjen kautta. Tutkimus nojaa sosiopsykologiseen teoriapohjaan, ja yhdistää näitä seitsemään sosiaalisen vaikuttamisen suunnitteluperiaatteeseen, jotka on kuvattu vaikuttavien suunnittelumenetelmien mallissa. Tämä väitöstyö tutkii vaikuttavien ohjelmistollisten ominaisuuksien osuutta käyttäytymisen muuttamisessa kohdistuen erityisesti siihen, miten loppukäyttäjää voidaan suostutella jakamaan palautetta ja ottamaan osaa interaktiiviseen yhteistyöhön. Työ koostuu viidestä määrällisestä tutkimuksesta, jotka vastaavat tutkimuskysymykseen: kuinka sosiaalisen vaikuttamisen suunnitteluperiaatteet voivat suostutella ja vakuuttaa ihmiset käyttämään julkisesti esilläolevia järjestelmiä, jotka on yhdistetty sosiaaliseen mediaan? Tutkimuksista yksi on Twitter-kyselytutkimus (403 vastaajaa) ja neljä tutkimusta tehtiin julkisesti esilläolevalla Twitter-pohjaisella järjestelmällä (284 vastaajaa). Tutkimusten tulokset osoittavat mainittujen suunnitteluperiaatteiden keskinäisen vuorovaikutuksen, sekä kuinka niiden avulla voidaan parantaa tietojärjestelmien vaikuttavuutta ja ennustaa tulevaa käyttöä. Tutkimustulosten pohjalta työssä luodaan viitekehys sosiaalisesti vaikuttavien järjestelmien tutkimukseen. Tämä viitekehys on keskeisessä asemassa pyrittäessä saavuttamaan syvällisempi ymmärrys siitä, kuinka käyttäjiä voidaan suostutella hyödyntämällä sosiaalista vaikuttamista. Viitekehystä voidaan käyttää myös vaikuttavien järjestelmien kehittämisessä.

The recent experience with the 2009 H1N1 pandemic has drawn attention to the need to better understand the public’s response to emergently released vaccines (ERV). This study applied a mixed methods approach to examine the causal pathways underlying the vaccination behaviour during a public health emergency. The integrated evidence from empirical and theoretical-based findings highlights a number of factors to consider in interventions to improve vaccination rates with an ERV. These factors include: 1) providing clear risk messages around the disease and the ERV, 2) improving accessibility to the vaccine, 3) encouraging primary healthcare providers to provide recommendations for vaccination, 4) implementing strategies to increase seasonal influenza vaccination prior to the next public health emergency, 5) developing strategies to target sub-populations more reluctant to accept an ERV. Developing theory-based interventions that are behaviour-specific may be more likely to result in behaviour change within the public in future emergency vaccination campaigns.

In today’s fast paced, ever-changing world, one cannot help hearing the terms Big Data and analytics. The Internet holds vast amounts of data and this data, for example in retail, is being used to predict shopping habits, current needs, trends, and more. Why should this be limited to the retail side of an organization? Today, there is a more significant push for Human Resource (HR) professionals to be strategic business partners, and, therefore, HR professionals need to work on leading, not lagging, in the area of measurements and analytics. Some organizations that have adopted the use of analytics in their HR departments have been extremely successful. If this is the case, why are not more HR professionals adopting the use of human resource analytics (HRA)? The purpose of this study is to gain insight as to the reasons why more HR professionals are not using HRA to improve organizational performance and to gain and maintain a competitive advantage. An exploration of prior research was performed and resulted in the development of a model representing factors that impact the adoption of HRA. The model was then tested for content validity and reliability using Partial Least Squares of Path Modeling. Results of the study of 302 HR professionals, currently working in the field of HR, suggest the hypotheses testing social influence, tool availability, effort expectancy, performance expectancy, and quantitative self-efficacy as factors impacting the adoption of HRA were all significant. Conversely, the factors data availability, fear appeals, and general self-efficacy were not significant. Findings indicate that the factors impacting the adoption of HRA are not only in the hands of the HR professional but, to some extent, the organization as well. If organizations truly want to adopt HRA, they must make available to the HR professionals the tools, data, resources, and support necessary. This study contributes to the literature on individual-level adoption, specifically of HRA. Implications for theory and practice are discussed, as well as further research.
