O IMPACTO DA INFLUÊNCIA SOCIAL SOBRE A INTENÇÃO DE USO DE SITES DE COMPRAS COLETIVAS: UM ESTUDO BASEADO NO MODELO UTAUT

A aceitação e o uso de Tecnologia da Informação (TI) pelo indivíduo têm sido estudadas por diferentes modelos conceituais que, em geral, derivaram de teorias da Psicologia como a TRA Theory of Reasoned Action e a TPB Theory of Planned Behavior, derivada da primeira. Um importante modelo de análise dai derivado, resultado da minuciosa análise de outros 8 modelos anteriores, o UTAUT - Unified Theory of Acceptance and Use of Technology de VENKATESH et. al. (2003) tem sido largamente analisado e validado em vários cenários de tecnologia e ambientes. Este trabalho visa compreender de uma maneira mais ampla dos fatores antecedentes da intenção de uso e comportamento de uso a partir do modelo UTAUT, bem como os fatores que melhores explicam a intenção e o comportamento de uso, assim como a análise de seus moderadores. Em seu desenvolvimento, Venkatesh et al. empreenderam comparações em três etapas de implantação e em dois cenários: na adoção mandatória, aquela em que se deu em ambiente empresarial onde o sistema é requerido para execução de processos e tomada de decisões, e na adoção voluntária, cenário em que a adoção se dá pelo indivíduo. No segundo caso, os autores concluíram que o fator influência social tem baixa magnitude e significância, não se revelando um fator importante na adoção da tecnologia. Este trabalho visa analisar também se o mesmo fenômeno ocorre para adoção que se dá de forma voluntária, mas passível de ser altamente influenciada pelos laços sociais, como o que ocorre entre usuários das redes sociais como Orkut, Facebook, Twitter e Linkedin, especialmente em tecnologias que habilitam ganhos associados ao exercício desses laços, como no caso do uso de sites de compras coletivas tais como Peixe Urbano, Groupon e Clickon. Com base no modelo UTAUT, foi aplicada uma pesquisa e posteriormente foram analisados os resultados de 292 respondentes validados que foram acessados por e-mails e redes sociais. A técnica de análise empregada consistiu do uso de modelagem por equações estruturais, com base no algoritmo PLS Partial Least Square, com bootstrap de 1000 reamostragens. Os resultados demonstraram alta magnitude e significância preditiva sobre a Intenção de uso da tecnologia pelos fatores de Expectativa de Desempenho (0,288@0,1%), Influência Social (0,176@0,1%). Os primeiro, compatível com estudos anteriores. Já a magnitude e significância do último fator resultou amplamente superior ao estudo original de Venkatesh et al. (2003) variando entre 0,02 a 0,04, não significante, dependendo dos dados estarem agrupados ou não (p.465). A principal conclusão deste estudo é que, ao considerarmos o fenômeno das compras coletivas, em um ambiente de adoção voluntária, portanto, o fator social é altamente influente na intenção de uso da tecnologia, o que contrasta fortemente com o estudo original do UTAUT (já que no estudo de Venkatesh et al. (2003) este fator não foi significante) e apresenta várias possibilidades de pesquisas futuras e possíveis implicações gerenciais.

ESTUDO DA ADOÇÃO INDIVIDUAL DA REDE SOCIAL PROFISSIONAL LINKEDIN

A intenção de rotatividade refere-se à probabilidade de os indivíduos deixarem o seu trabalho atual. Este tema se tornou relevante para as organizações por ser um potencial problema que pode afetar a competitividade das organizações, entre outros motivos. Acredita-se que alguns dos indivíduos com intenção de rotatividade possivelmente buscam meios de comunicação, novas tecnologias, como a rede social profissional LinkedIn objetivando disseminar suas informações profissionais, localizar oportunidades profissionais, obter mais contatos e informações sobre o mercado de trabalho, entre outras possibilidades. Desse modo, a intenção de rotatividade pode ser avaliada como um fator antecedente à adoção individual da rede social profissional LinkedIn. Este estudo analisou os fatores antecedentes que podem influenciar a intenção de uso e o comportamento de uso da rede social profissional LinkedIn, apoiando-se na perspectiva teórica da Teoria Unificada de Aceitação e Uso da Tecnologia (UTAUT), de Venkatesh et al (2003), e na escala de intenção de rotatividade, de Siqueira et al (2014) e Van Dam (2008). A pesquisa fundamenta-se em uma abordagem de investigação quantitativa na qual os dados foram coletados por meio de um instrumento de pesquisa com a obtenção de 292 questionários respondidos, o que possibilitou a validação dos relacionamentos entre os construtos componentes do modelo de pesquisa desenvolvido para o estudo da adoção individual da rede social profissional LinkedIn. Para realizar o teste das hipóteses do estudo, procedeu-se a análise de equações estruturais, com base no PLS-PM (Partial Least Squares Path Modeling) a partir do qual foram apresentadas medidas satisfatórias para os construtos investigados e o modelo proposto, sendo significativas todas as relações entre os construtos. Os resultados obtidos por esta pesquisa confirmam a influência dos fatores antecedentes Expectativa de Desempenho, Expectativa de Esforço, Influência Social e Intenção de Rotatividade na intenção de uso da rede social profissional LinkedIn. O estudo concluiu que Expectativa de Desempenho revelou-se o fator que mais influencia na intenção de uso do LinkedIn, pois há a percepção de que ao utilizar o LinkedIn pode-se obter benefícios profissionais, entre outros aspectos. O segundo fator que apresentou maior influência na intenção de uso do LinkedIn foi a intenção de rotatividade, uma vez que alguns dos indivíduos, ao adotarem o LinkedIn, provavelmente tendem a mostrar para as outras pessoas/organizações interessadas quais são os seus talentos, suas experiências, competências, além de obter mais contatos, entre outros motivos. Já a Expectativa de Esforço demonstrou que alguns indivíduos percebem que é fácil a interação desta tecnologia. A Influência Social constatou que existe a percepção dos indivíduos quanto à influência da sua rede de contatos na intenção de uso do LinkedIn.

CONCEITO DE MISSÃO EM JOHN STOTT E RENÉ PADILLA: RELAÇÃO ENTRE PROCLAMAÇÃO DA PALAVRA E AÇÃO SOCIAL

No presente estudo sobre o tema Conceito de Missão em John R. W. Stott e C. René Padilla procurei analisar a relação entre proclamação da palavra e ação social contextualizada no Evangelho. Esta dissertação desenvolvida no Programa da Pós-Graduação em Ciências da Religião, pertence à linha de pesquisa Religião, Sociedade e Cultura . A metodologia adotada na coleta de dados foi de uma revisão bibliográfica. O questionamento que norteou a pesquisa foi: qual o conceito de missão mundial em J. Stott e de missão integral em R. Padilla? Com as respostas obtidas, foi realizado um comparativo entre a teologia de ambos. No primeiro capítulo foi apresentado o conceito de missão mundial na teologia de J. Stott. No segundo capítulo, foi apresentado o conceito de missão integral na teologia de R. Padilla. Já no capítulo três, foi realizado um comparativo no qual ficou demonstrado que J. Stott em sua teologia da missão mundial prioriza a proclamação da palavra pela igreja, deixando o serviço de ação social para segundo plano, ao priorizar a necessidade da salvação da alma do pecador que se arrepende, mediante a aceitação Jesus Cristo como seu salvador. Em contrapartida, R. Padilla em sua teologia da missão integral coloca a proclamação da palavra e a prestação de serviço mediante a ação social de forma conjunta e indissociável para concretizar o anúncio do Reino de Deus na sociedade.

IMPACTO DO CONFLITO INTRAGRUPAL, DO SUPORTE SOCIAL NO TRABALHO E DO AUTOCONCEITO PROFISSIONAL SOBRE A RESILIÊNCIA: UM ESTUDO COM POLICIAIS MILITARES.

A resiliência é um construto que remete à habilidade do ser humano de ter êxito frente às adversidades da vida, superá-las e inclusive, ser fortalecido ou transformado por elas. Campos de investigações da psicologia, como Psicologia da Saúde, Psicologia Positiva e Comportamento Organizacional Positivo, têm considerado a resiliência como uma importante via para a compreensão dos aspectos positivos e saudáveis dos indivíduos. Este trabalho pretendeu ampliar o conhecimento acerca da resiliência e suas relações com outros construtos no contexto organizacional. Para isto, definiu-se como objetivo geral deste estudo verificar a capacidade preditiva do conflito intragrupal (tarefa e relacionamento), do suporte social no trabalho (emocional, informacional e instrumental) e do autoconceito profissional (saúde, realização, autoconfiança e competência) sobre a resiliência (adaptação ou aceitação positiva de mudanças, espiritualidade, resignação diante da vida, competência pessoal e persistência diante das dificuldades) de policiais militares. Participaram do estudo 133 policiais militares de um batalhão do interior do estado de São Paulo, prevalecendo indivíduos do sexo masculino (97,7%), com idade média de 30 anos (DP= 5,7). Para a medida das variáveis foram utilizadas as seguintes escalas validadas: Escala de Avaliação de Resiliência reduzida, Escala de Conflitos Intragrupais, Escala de Percepção de Suporte Social no Trabalho e a Escala de Autoconceito Profissional. Os dados foram submetidos a cálculos descritivos e a análises de regressão linear múltipla padrão. Os resultados indicaram que o modelo que reunia as variáveis antecedentes (conflito intragrupal, suporte social no trabalho e autoconceito profissional) explicou significativamente a variância das dimensões da resiliência: 30% da persistência diante das dificuldades, 29% da adaptação ou aceitação positiva de mudanças, 28% da competência pessoal e 11% da espiritualidade. As variáveis que tiveram impacto estatisticamente importante sobre a persistência diante das dificuldades foram o suporte emocional no trabalho, cuja direção da predição foi inversa, e autoconfiança, cuja direção da predição foi direta. A adaptação ou aceitação positiva de mudanças teve como preditor inverso a variável saúde e como preditor direto a autoconfiança. A competência pessoal teve impacto significativo da variável autoconfiança, que se mostrou um preditor direto. A espiritualidade, por sua vez, teve um único preditor significante, a variável realização, cuja direção da predição foi direta. Os resultados sugerem que dentre as variáveis antecedentes, o autoconceito profissional evidenciou maior poder de explicação da variância da resiliência. À luz da literatura da área foram discutidos estes achados. Por fim, foram apresentadas as limitações e a proposta de uma agenda de pesquisa que contribua para confirmação e ampliação dos resultados desta investigação.

Social and organizational impacts of emerging mobile devices:evaluating use

As mobile devices become increasingly diverse and continue to shrink in size and weight, their portability is enhanced but, unfortunately, their usability tends to suffer. Ultimately, the usability of mobile technologies determines their future success in terms of end-user acceptance and, thereafter, adoption and social impact. Widespread acceptance will not, however, be achieved if users’ interaction with mobile technology amounts to a negative experience. Mobile user interfaces need to be designed to meet the functional and sensory needs of users. Social and Organizational Impacts of Emerging Mobile Devices: Evaluating Use focuses on human-computer interaction related to the innovation and research in the design, evaluation, and use of innovative handheld, mobile, and wearable technologies in order to broaden the overall body of knowledge regarding such issues. It aims to provide an international forum for researchers, educators, and practitioners to advance knowledge and practice in all facets of design and evaluation of human interaction with mobile technologies.

Ethics and social responsibility - do HR professionals have the ‘courage to challenge’ or are they set to be permanent ‘bystanders'?

This paper considers the role of HR in ethics and social responsibility and questions why, despite an acceptance of a role in ethical stewardship, the HR profession appears to be reluctant to embrace its responsibilities in this area. The study explores how HR professionals see their role in relation to ethical stewardship of the organisation, and the factors that inhibit its execution. A survey of 113 UK-based HR professionals, working in both domestic and multinational corporations, was conducted to explore their perceptions of the role of HR in maintaining ethical and socially responsible action in their organisations, and to identify features of the organisational environment which might help or hinder this role being effectively carried out. The findings indicate that although there is a clear understanding of the expectations of ethical stewardship, HR professionals often face difficulties in fulfilling this role because of competing tensions and perceptions of their role within their organisations. A way forward is proposed, which draws on the positive individual factors highlighted in this research to explore how approaches to organisational development (through positive deviance) may reduce these tensions to enable the better fulfilment of ethical responsibilities within organisations. The involvement and active modelling of ethical behaviour by senior management, coupled with an open approach to surfacing organisational values and building HR procedures, which support socially responsible action, are crucial to achieving socially responsible organisations. Finally, this paper challenges the HR profession, through professional and academic institutions internationally, to embrace their role in achieving this. © 2013 Taylor & Francis.

An investigation into the acceptance of online banking in Saudi Arabia

Although a regional leader, Internet banking in Saudi Arabia is yet to be fully utilised as a value-adding tool to improve customer relationships and achieve cost advantages. The aim of this study was to identify the factors that encourage customers to adopt online banking in Saudi Arabia. The research constructs were developed based on the technology acceptance model (TAM) and incorporated some extra important control variables. The model was empirically verified to examine the factors influencing the online banking adoption behaviour of 400 customers. The findings of the study suggests that the quality of the Internet connection, the awareness of online banking and its benefits, the social influence and computer self-efficacy have significant effects on the perceived usefulness (PU) and perceived ease of use (PEOU) of online banking acceptance. Education, trust and resistance to change also have significant impact on the attitude towards the likelihood of adopting online banking. The implications of the findings are discussed and suggestions for future research are presented.

Tracing social influence in responses to strategy change in an online community

Interest into the effects of social influence on members of online communities is growing but there is a lack of knowledge about the impact of influential members in online communities on responses to strategy change within the wider community. We explore social influence in responses to strategy change through content analysis of forum posts before and after a change in strategy. Acceptance or non-acceptance of strategy change and subsequent positive and negative behavioural responses online are dependent on individual factors. The details of these behavioural responses to a change in strategy are tabulated and included in a conceptual model to inform decision-makers. Strategy change precipitates a reduction in social influence effects. Non-acceptance of strategy change is associated with competitor advertisement, inflammatory behaviour, offensive behaviour and complaints. This negative behaviour has important ramifications for acceptance of strategy change within the wider community and impacts on the viability of setting up online forums. © 2014 © 2014 Taylor & Francis.

Social change in Central and Eastern Europe: General trends and national patterns

The paper addresses five issue areas. First it describes the plurality of trajectories in central and eastern European transformations, offering a broad typology. Then it addresses the drift between acceptance of democracy and the market, owing to growing inequalities. Third, problems of poverty and exclusion are addressed. Fourth, it is addressed if any known model of redistribution emerged in the post-transition economies. Fifth, consequences of the populist turn in European policies are being analyzed. Influences of the EU practices will be dealt with and some preliminary conclusions drawn. These suggest a strong intertwining between social and economic performance that limit theoretically conceivable – neoliberal, social democratic, postmodern or conservative - policy choices.

Úton egy fenntartható gazdasági paradigma felé – A komplexitás befogadása a hálózati elméleteken keresztül (Towards a sustainable economic paradigm – Acceptance of the complexity through network theories)

Mára elkerülhetetlennek tűnik a gondolati váltás a gazdaságtudományok területén annak érdekében, hogy közelebb kerüljünk a hármas (gazdasági, társadalmi, környezeti) válságot előidéző problémák megoldásaihoz. A szerzők cikkükben amellett érvelnek, hogy a komplexitás befogadása kezdeti törekvésként értelmezhető azon az úton, amely a mindennapokban érzékelhető társadalmi és ökológiai problémák megoldásához vezet. Már léteznek olyan gazdaság- és vállalatelméletek, amelyek kezdik megkérdőjelezni az eddigi főáramú koncepciókat, és készek arra, hogy elveiket, elméleteiket a működési környezet bonyolultságát elfogadva alakítsák ki, és így találjanak mindennapos megoldásokat a gazdasági működésben. Ilyen például – a cikkben szereplő – IMP (Industrial Marketing and Purchasing) csoport hálózatelmélete. A szerzők azt kívánják bemutatni, hogy az ilyen hálózatelméletek alkalmasak arra, hogy a vállalatközi szférán túl is befolyásolják azt, ahogyan a vállalatok döntéseiket meghozzák és kapcsolataikat kezelik. ______ Today, it seems inevitable change of thought in the field of economics in order to get closer to solutions of problems which induced the triple (economic, social, environmental) crisis. In their article, the authors argue that the reception of complexity can be interpreted as an initial effort on the path that leads to the solutions of the everyday perceived social and ecological problems. The authors aim to present that the IMP (Industrial Marketing and Purchasing) group network theory is able to influence beyond the sphere of inter-company, that companies take their decisions and their relationships are treated.

Factors associated with social work student satisfaction with field placements in child welfare

This study was conducted during the 1994-1995 academic year. Seven social work education programs in the state of Florida, all accredited by the Council on Social Work Education, participated in this study. Graduate and undergraduate social work students in child welfare field placements, and their field instructors, were surveyed during the Spring 1995 semester to assess their satisfaction with field placements in this area and the relationship of this satisfaction to employment interests and field placement recommendations.^ The majority of social work students responding to this survey were generally satisfied with several aspects of their field placements--the learning, field work program, field instructor, child welfare agency, and overall field experience. The field instructors were generally more satisfied than the students, but only statistically different from the students in the areas of satisfaction with the field work program and the child welfare agency. Multiple regression analysis revealed that learning assignment opportunities, field instructor relationship characteristics, placement preference, and pre-placement interview contributed to the prediction of student satisfaction.^ Student satisfaction in field placement was significantly related to the acceptance of employment, if offered, and the recommendation of the field placement to other students. Logistic regression analysis revealed that satisfaction with the child welfare agency was the greatest contributor to the prediction of acceptance of employment, and satisfaction with the field work program was the greatest contributor to the prediction of field placement recommendation. ^

The boundaries of acceptance: Do expectations for the complainant's psychological injury affect legal decisions in a sexual harassment case

Research indicates that people engaged in legal decision-making use a host of biases and preconceptions to guide their decisions about whether the evidence presented to them is reasonable. However, few theories address how such expectations affect legal decision-makers. The present study attempted to determine if social judgment theory (SJT) can explain how and when legal decision-makers rely on expectations for the complainant's psychological injury in a hostile environment sexual harassment case. Two experiments provided undergraduate participants with a written summary of a hostile work environment allegation that first manipulated participants' expectations about reasonable psychological injuries (mild v. severe), and then presented them with actual severity levels of psychological injury (ranging from minimal to extreme). Experiment 1 (N = 295) hypothesized and found that participants who expected severe injuries perceived a greater range of psychological injuries to be reasonable than participants expecting mild injury. Experiment 2 ( N = 202) used similar methodology and investigated whether perceived reasonableness for the injury allegations affected legal decisions. Experiment 2 hypothesized that participants expecting severe psychological injury should render more pro-complainant decisions than participants expecting mild psychological injury. This result should be most pronounced when participants receive a moderate injury allegation, since this allegation was perceived as reasonable by participants expecting severe injury, but unreasonable by participants expecting mild injury. Consistent with SJT, participants who received a moderate injury but expected a severe injury found more liability than participants who received a moderate injury but expected a mild injury. Inconsistent with SJT, participants' expectations did not affect their compensatory damage decisions. In fact, more severe injury allegations increased damage awards regardless of participants' expectations. Although the results provide mixed support for applying SJT to legal decisions in sexual harassment cases, they emphasize the continuing role of oft-unstudied extra-legal factors (juror's expectations and psychological injury severity) on legal decisions.

Users Acceptance of Online Enrollment Processes in a Higher Education Institution

Little is known about students’ perceptions of online enrollment processes. Student satisfaction is part of the assessment required for accreditation, but evidence suggests that college administrators are oriented to retention and graduation rates rather than to consumer perception. The purpose of this descriptive quantitative study was to develop and validate a model that enables the measurement of online enrollment processes by the analysis of the students’ perceptions. The theoretical framework used to support this study was the process virtualization theory while the conceptual framework was based on Technology Acceptance Model (TAM). TAM is the most valid framework for studying user acceptance of technology and virtual processes. The model was modified, adding a new variable to fit this study. Research questions were used to determine if an institution knows how its students perceive online enrollment processes and how they can become more efficient and effective, improving usage and satisfaction. Descriptive data were collected and analyzed in phases: the pilot study phase, data collection phase, and analysis phases. Inferential statistics were used to draw information from sampled observations of the population; a Cronbach Alpha was conducted to determine the reliability and validity of the model. The study demonstrated that the modified TAM is valid, reliable, and fit to assess the perceptions of the users of online enrollment processes. This study will effect positive social change by providing enrollment managers and administrators information on how to analyze the acceptance their online enrollment processes from the perspective of their students as customers of an institution of higher learning.

Factors associated with social work student satisfaction with field placements in child welfare by Diane Elias Alperin.

This study was conducted during the 1994-1995 academic year. Seven social work education programs in the state of Florida, all accredited by the Council on Social Work Education, participated in this study. Graduate and undergraduate social work students in child welfare field placements, and their field instructors, were surveyed during the Spring 1995 semester to assess their satisfaction with field placements ii this area and the relationship of this satisfaction to employment interests and field placement recommendations. The majority of social work students responding to this survey were generally satisfied with several aspects of their field placements--the learning, field work program, field instructor, child welfare agency, and overall field experience. The field instructors were generally more satisfied than the students, but only statistically different from the students in the areas of satisfaction with the field work program and the child welfare agency. Multiple regression analysis revealed that learning assignment opportunities, field instructor relationship characteristics, placement preference, and pre-placement interview contributed to the prediction of student satisfaction. Student satisfaction in field placement was significantly related to the acceptance of employment, if offered, and the recommendation of the field placement to other students. Logistic regression analysis revealed that satisfaction with the child welfare agency was the greatest contributor to the prediction of acceptance of employment, and satisfaction with the field work program was the greatest contributor to the prediction of field placement recommendation.

Ansiedade social e cooperação em contexto de hierarquia social

The Ultimatum Game is a methodology of the Game Theory that intends to investigate the individuals cooperative behavior in situations of resources division. Studies have shown that half of the subjects don’t accept unfair division of resources, and prefer to bear a momentary cost to revenge the deceivers. However, people who have assertiveness impairment, such as social phobic individuals, could have some difficulties to reject unfair offer division resource, especially in situations that cause over anxiety, like being in the presence of an individual considered to be in a high hierarchical level. A negative perception about his own worth can also make the person thinks that he does not deserve a fair division. These individuals also have a strong desire to convey a positive impression to the others, which could cause them to be more generous in a resource division. The aim of this study was to verify, through the Ultimatum Game, if social anxiety individuals would accept more high confederate’s unfair offers that low confederate’s unfair offers; and if they would be more generous in goods division, in the same game, when compared to individuals without social anxiety. Ninety-five (95) college students participated in this study answering the Social Phobia Inventory, the Factorial Scale of Extroversion, socio-demographic questionnaire, situational anxiety scale and, finally, the Ultimatum Game in four rounds (1st and 3rd – confederate representing high or low ranking using an unfair proposal; 2nd – confederate without social status using fair proposal; 4th – subject’s research proposes the offer). The results showed a significant negative correlation between social anxiety and haughtiness, and social anxiety and assertiveness, and a significant positive correlation between social anxiety and situational anxiety. There was no significant difference in situational anxiety due to the status for anxious individuals. Also we found no significant difference in the amount of donated goods, showing that generous behavior does not differ between groups. Finally, the social status did not influence the decision in response to the game for anxious individuals. These results corroborate to other studies that show the relationship between social anxiety and assertiveness, and social anxiety and negative self-perception capability and value (low haughtiness). As show the results of situational anxiety scale, the high status stimulus was not perceived as threatening to the individual, which may have affected his answer in the game. The results for the Ultimatum Game follow the same direction as the acceptance rate for unfair proposals (approximately 50%) in studies with non-clinical sample.
