No. of bitstreams: 1 Lidiane_versão final.pdf: 1192433 bytes, checksum: 67cfa545ba2b857d12373b793715dea0 (MD5) / Two thousand and fifty six Senegalese clients of a Microfinance Institution (MFI) participated in the experiment during four months. They were divided in three groups: a control group that did not receive any messages, and two treatment groups, one in which clients received generic messages that simply said they should save money, and another group in which clients received messages that referred to the savings behavior of individuals who live in their neighborhood. The goal of this study is to assess whether receiving additional information about other participants from the same area where the participants live (neighborhood social capital) affects savings behavior. The results of this study show no significant impact of generic messages on savings behavior. Social capital effectively encourages deposits, which also makes withdrawals more salient since the accounts are fully liquid, but only among female clients. Limited attention, psychological reactance, salience, and gender issues emerge as possible explanations.

Avaliação de Sistemas de Mensagens Instantâneas Móveis (MIM): um estudo sobre o uso do Whatsapp com estudantes do ensino superior / Mobile Instant Messaging (MIM) system evaluation: a study on the whatsapp use with higher education students

Briskiewicz, Marcos Francisco 05 April 2018 (has links)
O imediatismo relacionado a troca de informações é uma realidade enfrentada pela população dos tempos modernos e o uso de sistemas de mensagens instantâneas móveis (MIM) é indispensável para que a comunicação aconteça da forma esperada. Atualmente a maioria da população mundial utiliza de sistemas MIM como meio de comunicação rápida e muitas vezes gratuita, com a finalidade de auxiliar a comunicação no ambiente de trabalho, troca de informações gerais e também como um meio de entretenimento. Devido a sua importância e eficácia é que diversas pesquisas buscam entender os fatores que determinam a adoção e o uso desses sistemas. Esta pesquisa tem como objetivo avaliar por meio da percepção de estudantes do ensino superior, os fatores que afetam o uso dos serviços de mensagens instantâneas móveis. Para alcançar este objetivo, foi realizada uma pesquisa survey com 1.386 estudantes de quatro instituições de ensino superior. Após a coleta foi realizada a modelagem das equações estruturais com o uso do software SmartPLS 2.0 para o cálculo dos mínimos quadrados parciais (Partial Least Squares - PLS), além do uso do Statistical Package for Social Sciences (SPSS) para a análise descritiva dos dados. Esta pesquisa obteve como resultado que o construto Qualidade do serviço influencia positivamente na Confirmação, bem como a Confirmação tem relação positiva com a Utilidade percebida, Prazer percebido, Interface do usuário e Segurança percebida. Prazer percebido e Interface do usuário tem relação positiva com a Satisfação e as relações entre Satisfação, Utilidade percebida e Prazer percebido influenciam positivamente na Intenção de continuidade de uso do sistema WhatsApp. Identificou-se que, no contexto desta pesquisa, o prazer e a satisfação atuam como fatores que influenciam diretamente na intenção de continuidade de uso do sistema WhatsApp, seguidos pela Utilidade, o que faz o uso deste sistema ser mais intuitivo do que prático. / Immediacy related to the exchange of information is a reality faced by the population of modern times and the use of mobile instant messaging (MIM) is indispensable for the communication to happen as expected. Today the majority of the world's population uses MIM systems as a fast and often free medium for the purpose of helping communication in the workplace, exchange of general information and also as a means of entertainment. Due to its importance and effectiveness, several studies seek to understand the factors that determine the adoption and use of these systems. This research aims to evaluate, through the perception of students of higher education, the factors that affect the use of mobile instant messaging services. To achieve this goal, a survey was conducted with 1,386 students from four higher education institutions. After the collection, the modeling of the structural equations was performed using the SmartPLS 2.0 software for the calculation of the partial least squares (PLS), besides the use of the Statistical Package for Social Sciences (SPSS) for the descriptive analysis of the data. This research has as a result that the Quality of Service construct positively influences Confirmation, as well as Confirmation has positive relation with Perceived Utility, Perceived Pleasure, User Interface and Perceived Security. Perceived pleasure and user interface has a positive relationship with satisfaction and the relationship between satisfaction, perceived utility and perceived enjoyment positively influences the intention to use the WhatsApp system. It was identified that, in the context of this research, pleasure and satisfaction act as factors that directly influence the intention to use WhatsApp system, followed by Utility, which makes the use of this system more intuitive than practical.
