Despite the increased numbers of online consumers, e-commerce growth is slow in the Kingdom of Saudi Arabia. In this correlational study, the technology acceptance model (TAM) was used as a theoretical framework to examine whether perceived ease of use of e-commerce platforms and perceived usefulness of e-commerce platforms could predict consumers' intention to adopt shopping online. A pre-existing TAM survey instrument was used to collect data from consumers (N = 95) who live in a City and have shopped at least once online. The regression analysis confirmed a positive statistically significant relationship between perceived ease of use of e-commerce platforms and consumers' intent to adopt online shopping. The results showed that perceived ease of use of e-commerce platforms and perceived usefulness of e-commerce platforms were statistically significant in predicting consumers' intent to adopt online shopping, with F(2, 92) = 241.630, p < .001, R2 = .840, and adjusted R2 = .837, and accounted for 84% of the variance in consumers' intent to adopt online shopping. The correlation between perceived ease of use and consumers' intent to adopt online shopping was (PEOU) r= .916, p < .001 and the correlation significance between perceived usefulness and consumers' intent to adopt online shopping was (PU) r= .591, p < .001. Using study results, retailers may be able to develop improved strategies to increase profitability via online shopping. The implications for positive social change include the potential for improved quality of life for consumers in Saudi Arabia.

現今智慧型手機之網路通路價值與電腦相比仍較低，也使得現今使用智慧型手機網路交易的比例仍低於使用電腦網路交易的比例。本研究採用付出為結構模型及恆等性分析，研究結果顯示，智慧型手機因其有用性及易用性較電腦低，因此使用者以手機網路交易的傾向也偏低。本研究以科技接受模型發現70%至80%的使用者都是因受社會及同儕影響，而較不傾向使用手機進行網路交易。一般認為，手機的便利性相對也使手機網路交易平台的風險提高。然而，研究結果顯示，以電腦從事網路交易的風險與手機網路交易的風險相當，便利性也幾無差異。因此本研究以社會影響為探討方向，認為其為影響現代人以手機從事網路交易的重要關鍵。 / The net channel value of smartphone driven mobile-commerce measured against the alternative of computer based electronic-commerce is at this point in time still low. In an exploratory effort structural modeling and invariance analysis reveals mobile commerce is viewed with a less positive usability disposition in the light of usefulness and effortlessness. An adaptation of the Technology Acceptance model accounting for 70-80% of usage intention indicates social influences experienced from peers to engage the mobile platform is lower. Convenience and perceived risk are usually considered attributes relatively important for the m-commerce platform. However, the analysis reveals little difference of these attributes' salience compared with e-commerce, absolute scores for convenience are similar, and perceived risk seems to have marginal effects on usage in general. Social influences, experienced as lower for mobile commerce is a especially salient concept in determining usability disposition and ultimately intention to use mobile commerce, as is the salience of the usability disposition larger for mobile commerce than for electronic commerce.

<p>This research work investigates and reports on the contribution of usability and perceptual frameworks towards understanding and ultimately increasing usage of a sales website and a corporate marketing website for a major insurance company in South Africa. It investigates whether the application of usability principles to the sales web positively influences the usage of the sales web system as a tool by intermediaries, and in so doing help the organisation recoup their investment and lower operational costs. This financial services (traditionally insurance) company, like many organisations, is in the process of migrating key operational systems onto web platforms to take advantage of benefits such as the ubiquity of web access and services orientated architecture among others. The research reviewed key frameworks in the area of technology acceptance or usage namely  Nielsen‟s usability attributes (Nielsen, 2003)  The Technology Acceptance Model (TAM), (Davis, 1989)&nbsp /  The Theory of Reasoned Action (Fishbein &amp / Ajzen, 1975)  The Theory of Planned Behavior (Ajzen, 1985) / and derived a theoretical summative model (the Conceptual Research Model) that combined both usability and perceptual dimensions. The applicability of this summative model was empirically tested using quantitative data relating to system&nbsp / usage and user perception. Empirical evidence was gathered to prove and refine the Conceptual Research Model (CRM), and the data substantiated the inclusion of the constructs in the CRM, as well as the efficacy of the model in a financial services organisation. Through testing of the CRM, this research has also confirmed which specific attributes of usability can be focussed on to bring about positive change in users‟ usage behaviour and adoption of a website or web application.</p>

當今智慧型手機成長快速，市場潛力大，影響消費者的智慧型手機購買決策因素成為近年來值得研究的議題。但過去有關智慧型手機購買決策的研究中，大多著重在手機的作業系統或是功能層面，並未將行動應用程式(APP)及人際面的影響因素納入考量。因此，本研究以網路外部性、科技接受模型及理性行為理論為基礎，分別從智慧型手機及行動應用程式的屬性面和人際面來探討，目的為找出影響台灣地區現有智慧型手機使用者對智慧型手機再購意圖的因素，並進一步探索這些因素如何影響使用者的態度及再購意圖。本研究結果發現： 1.智慧型手機屬性面：當使用者認為智慧型手機是越有用的、越具娛樂性的，則使用者對智慧型手機的採用態度越正向；當使用者認為智慧型手機是越容易使用的，並不會直接影響其對智慧型手機的態度。 2.智慧型手機人際面：當使用者認為有越多人使用智慧型手機，則使用者對智慧型手機的購買意圖越正向；而無論使用者認為其家人、伴侶、好友、同學或同事支不支持其使用智慧型手機，都不會影響其對智慧型手機的購買意圖。 3.行動應用程式屬性面：當使用者認為在短時間內行動應用程式的數量成長的越快速，則其對智慧型手機的態度會越正面；而無論使用者認為APP數量、種類的多少、價格是否可被接受以及APP的設計品質完不完善等，都不會直接影響使用者對智慧型手機的態度。 4.行動應用程式人際面：當使用者認為其家人、伴侶、好友、同學或同事越支持其使用行動應用程式時，使用者對智慧型手機的態度會越正向。

Aus der EINLEITUNG: Nicht immer sind organisationale Veränderungsprozesse von Erfolg gekrönt – wie bei 1000 befragten Unternehmen die vergleichsweise hohe Quote von 38 % an Prozessen belegt, die als gescheitert betrachtet werden [18]. Als häufigste Ursache werden dabei „Widerstände der Mitarbeiter“ genannt. Auch die Implementierung einer neuen Technologie in einer Organisation stellt einen derartig verändernden Eingriff dar, dessen Gelingen nicht zuletzt auch an die Nutzung der neuen Technologie geknüpft ist [10]. Um diesem Ziel gerecht zu werden, existieren in der Informatik zahlreiche Ansätze, die Schnittstellen zwischen Mensch und Technik anwenderfreundlich zu gestalten. Dabei ist insbesondere die Akzeptanz der (neuen) Technologie seitens der Nutzer von zentraler Bedeutung [5]. Denn wenn sich beispielsweise bei der Einführung eines ERP-Systems zur integrierten IT-Portfolio-Planung die Mitarbeiter überwacht und kontrolliert fühlen und aus diesen Motiven heraus Vorwände und Ausreden finden, das System nicht zu nutzen, können sie die Implementierung massiv beeinträchtigen und verzögern, was sich in erhöhtem Aufwand und höheren Kosten niederschlägt.

1 INTRODUCTION Since learning management systems (LMSs) are offering a great variety of channels and workspaces to facilitate information sharing and communication among learners during learning process, many educational organizations have adopted a specific LMS into their educational context. A LMS is a software that handles learning tasks such as creating course catalogs, registering students, providing access to course components, tracking students within courses, recording data about students, and providing reports about usage and outcomes to teachers [1]. LMSs include several applications such as OLAT, WebCT, Moodle, ATutor, Ilias, and Claroline. However, LMSs can be utilized to integrate a wide range of multimedia materials, blogs, forums, quizzes, and wikis. Therefore, the researchers suggest that studying the influence of technology usage on end-users, especially students, is fundamental in learning and teaching environment. Despite educational organizations routinely make decisions regarding the best pedagogical approaches for supporting students’ performance, there is very little research on the impact of LMSs on learning outcomes [2]. Indeed, a considerable number of studies were conducted to examine the adoption of various LMSs, whereas little researches focused on understanding how educational institutes can enhance learning and teaching process through a particular LMS [3]. Consistent with this, the researchers found virtually no research on investigating the relationship between LMSs usage and attitude toward learning. [...]

The emergence of cloud computing is influencing how businesses develop, re-engineer, and implement critical software applications. The cloud requires developers to elevate the importance of compliance with security policies, regulations and internal engineering standards in their software development life cycles. Cloud computing and agile development methodologies are new technologies associated with new approaches in the way computing services are provisioned and development of quality software enhanced. However adoption and use of agile and cloud computing by SMMEs in South Africa is seemingly constrained by a number of technical and non-technical challenges. Using Grounded Theory and case study method this study was aimed at exploring the development of a framework for agile methodologies to promote the adoption and use of cloud computing services by SMMEs in South Africa. Data was collected through survey and in-depth interviews. Open, Axial and Selective coding was used to analyse the data. In tandem with its main objective the study, besides exploring the development of the envisaged framework, also generated and made available valuable propositions and knowledge that SMMEs in South Africa using agile development methodologies can use to work better with cloud computing services in the country without compromising on software quality. The findings of this study and the emerging insights around the development of the framework, which in itself also constitutes an important decision making tool for supporting adoption and use of cloud computing services, are a substantial contribution to knowledge and practice in the ICT field of information systems in South Africa / Information Science / D.

No. of bitstreams: 1 AnnaCSN.pdf: 3032779 bytes, checksum: c9b62b38c5e42ff883e6b2946ccff0e1 (MD5) Previous issue date: 2009-09-04 / This study examines the factors that influence public managers in the adoption of advanced practices related to Information Security Management. This research used, as the basis of assertions, Security Standard ISO 27001:2005 and theoretical model based on TAM (Technology Acceptance Model) from Venkatesh and Davis (2000). The method adopted was field research of national scope with participation of eighty public administrators from states of Brazil, all of them managers and planners of state governments. The approach was quantitative and research methods were descriptive statistics, factor analysis and multiple linear regression for data analysis. The survey results showed correlation between the constructs of the TAM model (ease of use, perceptions of value, attitude and intention to use) and agreement with the assertions made in accordance with ISO 27001, showing that these factors influence the managers in adoption of such practices. On the other independent variables of the model (organizational profile, demographic profile and managers behavior) no significant correlation was identified with the assertions of the same standard, witch means the need for expansion researches using such constructs. It is hoped that this study may contribute positively to the progress on discussions about Information Security Management, Adoption of Safety Standards and Technology Acceptance Model / Este estudo analisa os fatores que influenciam os gestores p?blicos na ado??o de pr?ticas van?adas de Gest?o de Seguran?a da Informa??o. A pesquisa utilizou como base assertivas a Norma de Seguran?a ISO 27001:2005 e modelo te?rico baseado no TAM (Technology Acceptance Model) descrito em Venkatesh e Davis (2000). O m?todo adotado foi a esquisa de campo de alcance nacional que contou com a participa??o de oitenta gestores p?blicos dos Estados do Brasil, sendo todos coordenadores na ?rea de gest?o e planejamento dos governos estaduais. A abordagem da pesquisa foi quantitativa e foram utilizados m?todos de estat?stica descritiva, an?lise fatorial e regress?o linear m?ltipla para an?lise dos dados. Os resultados da pesquisa apresentaram correla??o entre os construtos do modelo TAM (facilidade na utiliza??o, percep??o sobre a utilidade, atitude e inten??o de utiliza??o) e a concord?ncia com as assertivas elaboradas de acordo com a norma ISO 27001, demonstrando que estes fatores influenciam os gestores na ado??o de tais pr?ticas. J? as outras vari?veis independentes do modelo (perfil organizacional, perfil demogr?fico e comportamental dos gestores) n?o tiveram correla??o significante com as assertivas da referida norma, demonstrando necessidade de amplia??o de pesquisas com utiliza??o de tais construtos. Espera-se que este estudo possa contribuir de forma positiva ao avan?o nas discuss?es sobre o tema Gest?o de Seguran?a da Informa??o e Ado??o de Normas de Seguran?a, bem como, Modelos de Aceita??o de Tecnologia
