In order to support the implementation of these systems, several technologies came up or evolved with this purpose, namely the programming languages. The Technology Acceptance Model TAM (Davis, 1986) was conceived aiming to evaluate the acceptance/use of information technologies by their users. A lot of studies and many applications have used the TAM, however, in the literature it was not found a mention of the use of such model related to the use of programming languages. This study aims to investigate which factors influence the use of programming languages on the development of Web systems by their developers, applying an extension of the TAM, proposed in this work. To do so, a research was done with Web developers in two Yahoo groups: java-br and python-brasil, where 26 Java questionnaires and 39 Python questionnaires were fully answered. The questionnaire had general questions and questions which measured intrinsic and extrinsic factors of the programming languages, the perceived usefulness, the perceived ease of use, the attitude toward the using and the programming language use. Most of the respondents were men, graduate, between 20 and 30 years old, working in the southeast and south regions. The research was descriptive in the sense of its objectives. Statistical tools, descriptive statistics, main components and linear regression analysis were used for the data analysis. The foremost research results were: Java and Python have machine independence, extensibility, generality and reliability; Java and Python are more used by corporations and international organizations than supported by the government or educational institutions; there are more Java programmers than Python programmers; the perceived usefulness is influenced by the perceived ease of use; the generality and the extensibility are intrinsic factors of programming languages which influence the perceived ease of use; the perceived ease of use influences the attitude toward the using of the programming language / A difus?o da Web impulsionou a dissemina??o de Sistemas de Informa??o (SI) baseados na Web. Para apoiar a implementa??o desses sistemas, diversas tecnologias surgiram ou evolu?ram com este prop?sito, dentre elas as linguagens de programa??o. O Modelo de Aceita??o de Tecnologia - TAM (Davis, 1986) foi concebido com o intuito de avaliar a aceita??o/uso de tecnologias da informa??o por seus usu?rios. V?rios estudos e aplica??es diversas t?m utilizado o TAM, no entanto, n?o foi encontrada na literatura men??o a utiliza??o de tal modelo com rela??o ao uso de linguagens de programa??o. Este estudo objetiva investigar que fatores influenciam o uso de linguagens de programa??o utilizadas no desenvolvimento de sistemas Web por parte de seus desenvolvedores, utilizando uma extens?o do TAM, proposta neste estudo. Para tanto, foi realizada uma pesquisa com desenvolvedores Web pertencentes a dois grupos do Yahoo: java-br e python-brasil, no qual foram respondidos, na ?ntegra, 26 question?rios Java e 39 Python. O question?rio tinha quest?es de car?ter geral e quest?es que mediam os fatores intr?nsecos e extr?nsecos das linguagens de programa??o, a utilidade percebida, a facilidade de uso percebida, a atitude sobre o uso e o uso da linguagem de programa??o. A maioria dos respondentes eram homens, com n?vel superior, idade entre 20 e 30 anos, atuando nas regi?es sudeste e sul. Do ponto de vista de seus objetivos, a pesquisa foi descritiva. Em rela??o ? forma de abordagem, quantitativa. Para a an?lise de dados foram utilizadas ferramentas estat?sticas, estat?stica descritiva, componentes principais e an?lise de regress?o linear m?ltipla. Os principais resultados da pesquisa foram: Java e Python possuem independ?ncia de m?quina, extensibilidade, generalidade e confian?a; Java e Python s?o mais utilizadas por corpora??es e organiza??es internacionais do que apoiadas pelo governo ou institui??es de ensino; h? mais programadores Java do que Python; a utilidade percebida ? influenciada pela facilidade de uso percebida; a generalidade e a extensibilidade s?o fatores intr?nsecos as linguagens de programa??o que influenciam a facilidade de uso percebida; a facilidade de uso percebida influencia a atitude em rela??o ao uso da linguagem de programa??o

Internal marketing and internal communication are essential tools to align em-ployees’ mindsets with the necessary tasks which bring about employee satis-faction and organisational prosperity. Electronic newsletters serve as an internal marketing communication medium which can convey the necessary information to employees regarding the organisation’s goals and objectives. They also act as a medium to build relationships with employees and encourage improved service delivery and customer-oriented employee mindsets. Employees’ willingness to make use of electronic newsletters for the purpose of disseminating organisational information is an indication of employees’ acceptance of the organisational information and use thereof in performing organisational tasks successfully as the organisation intends. The purpose of the current study was to determine employees’ acceptance of electronic newsletters, as an internal marketing communication medium, in order to disseminate organisational information which contributes to the attainment of organisational goals, objectives and success. An empirical study was conducted to determine employees’ acceptance of elec-tronic newsletters by means of an adapted technology acceptance model, self-administered, e-mail survey disseminated to employees of a higher education institution. The study followed a quantitative research approach, utilising re-gression in the analysis of the data. Based on the research results, employees do accept the electronic newsletter for the dissemination of organisational information, albeit with suggestions on how it can be better utilised in future. / Business Management / M.

Some aspects that enhance the use of intentions can be essential for the individual to choose whether or not a particular technology. This study examined the background factors that can influence the intended use of the Virtual Library of an Institution of Higher Education. Among the conceptual models studying the adoption of information technology, it was decided in this study the use of Technology Acceptance Model (TAM) proposed by Davis (1986). In this model the external variables were also added stimulus Professor and smoker in order to expand the power of explanation of the intended use of the users in question. Through a quantitative research approach, data were collected through a survey tool to obtain 406 questionnaires responses. The results of this research confirms that the influence of various factors positioned in different dimensions provide findings relevant to the adoption of virtual library. It concludes that the Teacher Incentive positively influences Ease of Use, Perceived Usefulness and the Habit of undergraduate students on the intended use of the Virtual Library. Thus, it was found that the influence of the teacher becomes a determining factor in the use of virtual library intention, which emphasizes the importance of guidance and recommendation of teachers in the use of this technological tool. The study concluded that the perceived usefulness proved to be the factor that most influences the intention to use this technology because there is a perception that if the student will use the virtual library, you can improve your performance in studies, among others. The habit can also influence the adoption of a virtual library in parallel to perceptions about the benefits that can be obtained from the use of this technology. / Diversos estudos sobre a aceitação e o uso de tecnologias de informação têm sido realizados por diferentes modelos conceituais que buscam demonstrar a existência de fatores que influenciam a intenção e comportamento dos usuários sobre um determinado sistema de informação. Alguns aspectos que potencializam as intenções de uso podem ser fundamentais para que o indivíduo adote, ou não, uma determinada tecnologia. Este estudo analisou os fatores antecedentes que podem influenciar a intenção de uso da Biblioteca Virtual de uma Instituição de Ensino Superior (IES). Dentre os modelos conceituais que estudam a adoção de tecnologias de informação, optou-se nesta pesquisa pelo Modelo de Aceitação de Tecnologia (TAM) proposto por Davis (1986). Neste modelo ainda foram adicionadas as variáveis externas Estímulo Docente e Hábito a fim de ampliar o poder de explicação da intenção de uso dos usuários em questão. Através de uma abordagem de investigação quantitativa, os dados foram coletados por meio de um instrumento de pesquisa com obtenção de resposta de 406 questionários. Os resultados obtidos por esta pesquisa confirmam a influência de diversos fatores posicionados em diferentes dimensões e proporcionam conclusões relevantes à adoção da biblioteca virtual. Conclui-se que o Estímulo Docente influencia positivamente a Facilidade de Uso, Utilidade Percebida e o Habito dos alunos de graduação sobre a intenção de uso da Biblioteca Virtual. Com isso, constatou-se que a influência do professor torna-se um fator determinante na intenção de uso da biblioteca virtual, o que ressalta a importância da orientação e recomendação dos professores no uso desta ferramenta tecnológica. O estudo concluiu que a utilidade percebida revelou-se o fator que mais influencia a intenção de uso desta tecnologia, pois há a percepção de que, caso o aluno venha utilizar a biblioteca virtual, pode-se melhorar seu desempenho nos estudos, entre outros aspectos. O Hábito também pode influenciar à adoção da biblioteca virtual de forma paralela às percepções sobre os benefícios que podem ser obtidos com o uso desta tecnologia.

Survey was applied with 162 teachers at distance of Universidade Federal da Paraíba Virtual, issue focusing on the perceived characteristics of innovation, attitude and intention about the use of Moodle. Multivariate statistical techniques were performed: 1) content-vality to analyze the complete structure of scale for relevance and representativeness of items and to verify which items refer to construct in question; 2) exploratory factory analysis to know the structure of interrelationship of the original variables of IDT; 3) confirmatory factor analysis to guarantee conceptual validity for the pattern observed; 4) coefficient alpha to verify the homogeneity of set of items; 5) ANOVA to verify the likely differences between the groups of respondents; and 6) multiple regression analysis to analyze the relation between constructs. Results showed that not all factors of IDT had effect on attitude and intention. Only three constructs had significant effect on attitude and/or intention: relative advantage+compatibility for work style (β = 0,792), visibility (β = 0,166) and result demonstrability (β = 0,152). Moreover, teachers had a positive attitude in relation to use of Moodle and a positive intention in relation to use in the future. It was not possible to confirm all the relation of TAM, probably this verification was been compromised for some problems in the measurement process, thus, the only unsupported relationship of TAM was the effect of complexity on attitude. An academic contribution was that although some constructs of IDT did not show effect on the constructs of TAM, the model provided evidence of appropriated application of constructs of TAM with IDT to measure attitude and intention of use of Moodle. A management contribution was the understanding and prediction the teacher s behavior in relation to adoption and use process of Moodle, being possible to verify the effectiveness of innovative project of distance learning in the UFPB Virtual. / Nesse estudo, o modelo de pesquisa baseado no modelo de aceitação da tecnologia (Technology Acceptance Model - TAM) (DAVIS et al., 1989) e na teoria da difusão da inovação (Innovation Diffusion Theory - IDT) (ROGERS, 2003) foi usado para analisar a relação entre as características de inovação e o comportamento dos docentes no processo de adoção e de uso do Moodle em cursos de graduação a distância. Foi utilizada uma estratégia de levantamento (survey) aplicado a 162 docentes a distância da Universidade Federal da Paraíba Virtual, focando questão sobre as características percebidas de inovação, atitude e intenção em torno do uso do Moodle. Foram realizadas técnicas estatísticas multivariadas: 1) validação de translação para analisar a estrutura completa das escalas em relação à pertinência e representatividade dos itens e a verificação de que os itens propostos remetem ao construto em questão; 2) análise fatorial exploratória para conhecer a estrutura das inter-relações das variáveis originais da IDT; 3) análise fatorial confirmatória para garantir a validade conceitual para os padrões observados; 4) alpha de Cronbach para verificar a homogeneidade do conjunto de itens das escalas; 5) ANOVA para verificar as possíveis diferenças entre os grupos de respondentes; e 6) análise de regressão múltipla para analisar a relação entre os construtos. Os resultados revelaram que nem todos os fatores da IDT tiveram efeito sobre atitude e intenção. Apenas três construtos apresentaram efeito significativo sobre a atitude e/ou intenção: avanço relativo+compatibilidade por estilo de trabalho (β = 0,792), visibilidade (β = 0,166) e demonstrabilidade de resultado (β = 0,152). Além disso, os docentes tiveram uma atitude positiva em relação ao uso do Moodle bem como uma intenção positiva em relação ao seu uso futuro. Não foi possível confirmar todos os relacionamentos do TAM, provavelmente essa verificação foi comprometida por alguns problemas no processo de mensuração das escalas, sendo assim, o único relacionamento do TAM não suportado foi o efeito de complexidade sobre atitude. Uma contribuição acadêmica foi que apesar de alguns construtos da IDT não terem apresentado efeito sobre os construtos do TAM, o modelo forneceu evidência de aplicação apropriada dos construtos do TAM com os da IDT para medir a atitude e intenção de uso do Moodle. Uma contribuição gerencial foi a compreensão e previsão do comportamento dos docentes EaD em relação ao processo de adoção e uso do Moodle, possibilitando verificar a efetividade do projeto inovador de EaD na UFPB Virtual.

The growing popularity of the internet and its activities have opened a wide range of business opportunities especially in terms of e-business. Though, reports show that the adoption rate of e-commerce in developed countries seem to be striving, a lot of developing countries still struggle with slow e-commerce adoption rate. Democratic Republic of Congo (DRC) is one these countries where e-commerce adoption is still in its infant stages. However, because of the recent infrastructure improvements and the growth in telecommunication services in the country, internet penetration, more specifically, mobile Internet penetration is growing at a significantly fast pace. This could mean opportunities for e-business services in DRC. The objective of this research is to investigate the factors that could influence online shopping adoption in DRC. This investigation was carried out by adapting an extended version of the Technology Acceptance Model (TAM). A quantitative approach was used in the collection of data and the data was edited and analyzed using the programming language, R. Also, the analytical techniques used in conducting this research include: Descriptive Statistical Methods (Cross tabulation, frequencies) and inferential Statistical Methods (Logistic Regression, ANOVA and Chi square tests). The results from this research show that contrary to the conceptualized model in the literature review where the main constructs included: Perceived Ease of Use(PEOU), Perceived Usefulness(PU) and Perceived Trust(PT), it appears that Perceived Ease of Use(PEOU) does not have any significance in a user’s intention to shop online(p>0.01). However, this research found that Perceived Usefulness and Perceived Trust have a strong statistical significance to a user’s intention to shop online. Furthermore, we found that Gender, Income and Age do not have any moderating influence on the relationship between a user’s perception and their intention to shop online in DRC. However, when the relationship between VI perception and intention to shop online is moderated by experience, we find that there is a variation between users with prior online shopping experience and those without. While these research findings make for remarkable recommendations on a user’s intention to shop online, we recommend that further research on actual usage of e-commerce be examined in DRC to get a better understanding of consumer online behaviors.

Purpose – It is argued that traditional audit methods are becoming outdated in terms of delivering sufficient assurance on business objectives, whereby, a paradigm shift towards continuous auditing (CA) is proposed and perceived as necessary both by academia, standard-setting groups, and business society. However, the practical prevalence of CA is insignificant in relation to the expectations depicted. Therefore, the purpose of this paper is to examine why this is the case by means of investigating what factors that motivate an adoption of CA amongst various internal audit functions (IAFs). Design/methodology/approach – The study draws on the Technology Acceptance Model (TAM), and data are obtained through semi-structured interviews capturing internal auditors’ attitude towards CA, and what factors that influence an adoption. Findings – There is a shattered view on CA amongst IAFs, where the proponents embrace it as a set of value-adding methodologies whilst the opponents argue that it falls outside their responsibility and threaten the independence of the function. Thus, why CA has not been leveraged to its full potential is, in contrast to previous research, not solely attributable to practical factors but also due to the IAFs’ vast differences in approach to CA as a concept. Practical implications – The study has brought attention to the distinguished disparity found in internal auditors’ attitude towards CA. Ultimately, doubts, whether CA should be leveraged by IAFs has come to light. These are hurdles that need to be considered, both by academia, standard-setting groups, and business society if the leap for CA ought to continue. Originality/value – The use of semi-structured interviews contributes to in-depth understandings and insights of the internal auditors’ attitudes towards CA. Moreover, such an approach is more likely to capture the stance towards CA in greater detail than that possible of previous large-scale surveys.

Groupware packages are increasingly being used to support content delivery, class discussion, student to student and student to faculty interactions and group work on projects. This research focused on groupware packages that are used to support students who are located in different places, but who are assigned group projects as part of their coursework requirements. In many cases, students are being asked to use unfamiliar technologies that are very different from those that support personal productivity. For example, computer-assisted cooperative work (CSCW) technology is different from other more traditional, stand-alone software applications because it requires the user to interact with the computer as well as other users. However, familiarity with the technology is not the only requirement for successful completion of a group assigned project. For a group to be successful, it must also have a desire to work together on the project. If this pre-requisite is not present within the group, then the technology will only create additional communication and coordination barriers. How much of an impact does each of these factors have on the acceptance of CSCW technology? The significance of this study is threefold. First, this research contributed to how a user's predisposition toward group work affects their acceptance of CSCW technology. Second, it helped identify ways to overcome some of the obstacles associated with group work and the use of CSCW technology in an academic online environment. Finally, it helped identify early adopters of CSCW software and how these users can form the critical mass required to diffuse the technology. This dissertation reports the impact of predisposition toward group work and prior computer experience on the intention to use synchronous CSCW. It was found that predisposition toward group work was not only positively associated to perceived usefulness; it was also related to intention to use. It also found that perceived ease of use, at least in this study, had a direct and positive impact on intention, and was not mediated through perceived usefulness. These findings hold implications for academia and how it uses complex collaborative software. Avenues for further research are identified.

The purpose of this study is to determine whether the style of a user interface (i.e., its look and feel) has an effect on the usability of a synchronous computer supported cooperative work (CSCW) environment for delivering Internet-based collaborative content. The problem motivating this study is that people who are located in different places need to be able to communicate with one another. One way to do this is by using complex computer tools that allow users to share information, documents, programs, etc. As an increasing number of business organizations require workers to use these types of complex communication tools, it is important to determine how users regard these types of tools and whether they are perceived to be useful. If a tool, or interface, is not perceived to be useful then it is often not used, or used ineffectively. As organizations strive to improve communication with and among users by providing more Internet-based collaborative environments, the users' experience in this form of delivery may be tied to a style of user interface look and feel that could negatively affect their overall acceptance and satisfaction of the collaborative environment. The significance of this study is that it applies the technology acceptance model (TAM) as a tool for evaluating style of user interface look and feel in a collaborative environment, and attempts to predict which factors of that model, perceived ease of use and/or perceived usefulness, could lead to better acceptance of collaborative tools within an organization.

Internet voting (i-voting) has been researched since countries started trialing it two decades ago. Although several countries have abandoned their trials, some implemented i-voting in national elections. I-voting research discusses successful implementations of i-voting in countries such as Estonia, Switzerland, and Canada, which has generated many different factors for successful adoption. However, no systematic literature review (SLR) on i-voting adoption factors has been identified. The problem that this thesis addresses is the lack of a comprehensive overview on reasons why an individual decides to adopt an i-voting solution. Thus, the purpose of this thesis is “to identify i-voting adoption factors on the individual level”. This study aims to answer the following research question: “How can TAM be adapted to explain an individual’s intention to adopt i-voting?” A semi systematic literature review of 117 articles is used that contains articles spanning two decades of i-voting research. The scope is narrowed down to adoption factors on the individual level and include the non-technical factors: “Voter experiences and perceptions”, “Trust”, and “Education”, and the technical factors: “User experience”, and “Performance”. The technology acceptance model (TAM) is used to explain how the factors relate to Perceived Ease of Use (PEOU) and Perceived Usability (PU) within TAM. A suggestion of an extended model is also made that includes other factors which were identified to explain individual adoption. Thus, the conclusion of this thesis is that TAM can in part explain an individual’s intention to adopt i-voting, but that it should be adapted to include the following additional factors: “Trust”, “Demographics”, “Education”, and “Voter experiences and perceptions”. Recommendations for future research on i-voting, limitations, and ethical and societal consequences are also discussed.
