Background: Information Communication Technologies (ICT)-mediated support can reduce family caregiver burden and may bridge service gaps caused by time constraints and language or cultural barriers. (Non)-usage behaviour can be explained using Andersen’s Behavioural Model of Health Service Utilization, Venkatesh’s Unified Theory of Use and Acceptance of Technology, Eysenbach’s Law of Attrition, and Wilson’s and Chatman’s Information Behaviour Theories. Purpose: This study aimed to describe and explain (non)-usage behaviour of ehealth services among Chinese caregivers. Method: This two-phase study used a mixed methods design involving 46 Chinese caregivers who cared for a family member with dementia. Usability of the ICT tools designed in the study was tested. Phase I participants (N=28) had access to a bilingual information site and personalized email support from professionals. Phase II participants (N=18) were randomized to use one of three enhanced features. Pre- and post-intervention data were collected, and qualitative interviews were conducted. Results: The Phase I ICT tools supported the core functions without major usability issues. Perceived efforts to use the ICT-mediated services influenced the consent decisions of Phase I caregivers (p=.036). Caregivers initiated service earlier if they had a higher acceptance of the service (p=0.017). Frequent users of email support experienced a decline of perceived burden compared with an escalation of perceived burden by non-users (p=0.023). An older age, greater caregiving competence, and lower English or computer proficiency explained non-usage behaviour. Requirements were identified to enhance the Phase I ICT tools. In Phase II, a test of three enhanced features showed there was no major usability issue. The intervention study found the enhanced features did not influence email use as hypothesized. Qualitative analysis showed usage patterns were explained by caregiver needs, caregiving beliefs, personal capacity, social support, ICT factors, and style of use. Non-users preferred Chinese to English compared with users (p=0.046). Integrating the theories and empirical findings, three concepts were developed to explain (non)-usage behaviour: usage in context, usage paths, and stages of use. Conclusion: Usage and non-usage behaviour can be explained by the service needs in the caregiving context, the use of non-ICT-mediated resources, and the access barriers to Internet use. Use of ICT-based support can be beneficial to caregivers if they do not drop out of the service.

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. [...]

1 EINLEITUNG Nachdem in den vergangenen Jahren die Bedeutung von Web 2.0-Anwendungen neben dem privaten vor allem auch für den unternehmerischen Bereich untersucht wurde [18], werden seit einiger Zeit auch Einsatzmöglichkeiten in Forschung und Lehre berücksichtigt. Wagner und Schroeder zufolge ermöglicht die Nutzung von Web 2.0-Anwendungen die gemeinsame Schaffung von Inhalten im Internet, die häufigen und unvorhergesehenen Änderungen unterliegen [24]. Viele dieser Anwendungen sind hedonistisch [10] und im privaten Internetnutzungsverhalten von Studenten weit verbreitet [27]. Bereits 2009 hatten Kane und Fichman gefordert, die Möglichkeiten, die die neuen webbasierten Technologien als IT-basierte Kooperationswerkzeuge für den Umgang von Studierenden, Lehrenden und Forschern unter- und miteinander bieten, stärker zu untersuchen [14]. Erste Studien haben sich seitdem mit dem studentischen Arbeitsalltag, in dem Web 2.0 eingesetzt wird, um Kursinhalte unter Kommilitonen zu besprechen und zu verarbeiten [17] oder um gemeinschaftliches Lernen besser zu gestalten [15,16] beschäftigt. Weitere Untersuchungen widmen sich sozialpsychologischen Aspekten, wie z.B. der Frage, wie sich Studierende durch Web 2.0 schneller an das Universitätsleben gewöhnen können [4] oder welche Rolle soziale Netzwerkseiten, wie z.B. Facebook, bei der Formung der studentischen Identität spielen [22]. Die Frage, wie Unterrichtende Web 2.0-Anwendungen nutzen können, um ihre Lehrinhalte zu unterstützen, wurde ebenfalls adressiert [7], wobei insbesondere die Anpassung bestehender Anwendungen auf Unterrichtsbedürfnisse im Mittelpunkt stand [9].

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.

[pt] Confiança é um elemento essencial na construção de relacionamentos. Esta tese de doutorado propõe um modelo que trata a confiança como um construto multidimensional mediador na construção da intenção do consumidor de comprar produtos e serviços usando um dispositivo móvel. O estudo aborda os impactos do tipo de produto sobre as relações entre confiança e intenção de compra via dispositivo móvel, compara três modelos que utilizam diferentes versões do construto confiança e considera características inovadoras da tecnologia móvel na construção da confiança, a fim de aprofundar o conhecimento existente sobre as relações de confiança envolvendo compra de produtos e serviços em contextos móveis. Os dados utilizados foram coletados por meio de um levantamento online e analisados pelo método de modelagem de equações estruturais. Os resultados mostram a importância da utilização de construtos multidimensionais para a confiança e o papel desta como mediadora entre as características inovadoras dos dispositivos móveis e a adoção destes para compras de produtos e serviços, os efeitos dos produtos de busca sobre a atitude e os efeitos dos produtos de experiência sobre a intenção de compra, e a importância da facilidade de uso dos dispositivos móveis e da competência dos vendedores para a adoção e uso de dispositivos móveis para a compra de bens e serviços. / [en] Trust is an core element in relationships. This dissertation proposes a model in which a multidimensional trust construct mediates consumer intention to purchase products and services using a mobile device. This study also analises impacts of product type on the proposed relations and compares three different models each one using an alternative representation of trust in order to expand academic knowledge regarding trusting relationships in mobile contexts. An online survey using social networks provided the data used in a structural equation modeling analysis. Results show that trust constructs should be multidimensional whenever trust is a construct of importance, that trust mediates the relationships between mobile devices innovative characteristics and adoption of mobile commerce, that search and experience products produce different effects, and that ease of use of mobile devices and vendor competence play important parts in the adoption and use of mobile commerce.

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

No. of bitstreams: 1 CristinaKNY_DISSERT.pdf: 2647899 bytes, checksum: 38fec83f99c6340d8c2475bec099d1b8 (MD5) Previous issue date: 2010-09-03 / In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ?) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public. Keywords: Technology / Nas ?ltimas d?cadas o setor p?blico vem sofrendo press?es com vistas a melhorar seu desempenho. A utiliza??o da Tecnologia da Informa??o (TI) tem sido uma ferramenta cada vez mais empregada na tentativa de alcan?ar esse objetivo. Dessa forma, passou a ser uma importante quest?o nas organiza??es p?blicas, e em particular nas institui??es de ensino superior, verificar quais fatores influenciam a aceita??o e o uso da tecnologia, impactando no sucesso de sua implementa??o e nos resultados organizacionais almejados. O Modelo de Aceita??o da Tecnologia TAM foi utilizado como base para o presente estudo e fundamenta-se nos construtos utilidade percebida e facilidade de uso percebida. No entanto, quando se trata de sistemas integrados de gest?o, devido ? complexidade de sua implanta??o, acrescentaram-se fatores organizacionais para assim buscar maior explica??o da aceita??o desses sistemas. Assim, acrescentaram-se ao modelo TAM cinco construtos relacionados aos fatores cr?ticos de sucesso na implementa??o de sistemas ERP, s?o eles: apoio da alta administra??o, comunica??o, treinamento, coopera??o, e complexidade tecnol?gica (BUENO e SALMERON, 2008). Com base no exposto, lan?a-se o seguinte problema de pesquisa: quais fatores influenciam a aceita??o e uso do SIE/m?dulo acad?mico na Universidade Federal do Par?, a partir da percep??o dos usu?rios t?cnicos e docentes? O objetivo geral da pesquisa foi identificar a influ?ncia de fatores organizacionais e comportamentais como antecedentes da inten??o comportamental de uso do SIE/m?dulo acad?mico na UFPA sob a perspectiva dos usu?rios docentes e t?cnicos. A presente pesquisa ? aplicada, explorat?ria e descritiva, de natureza quantitativa com a aplica??o de um survey, e a coleta de dados se deu por meio de question?rio estruturado aplicado a uma amostra composta por 229 docentes e 30 t?cnico-administrativos. A an?lise de dados se deu atrav?s de estat?sticas descritivas e modelagem de equa??o estrutural com a t?cnica de m?nimos quadros parciais (Partial Least Square-PLS). Primeiramente efetuou-se a avalia??o do modelo de mensura??o, no qual foram verificadas a confiabilidade, validade convergente e discriminante para todos os indicadores e construtos. Em seguida, o modelo estrutural foi analisado, com a utiliza??o de bootstrap como t?cnica de reamostragem. Na avalia??o das signific?ncias estat?sticas, todas as hip?teses formuladas foram suportadas. O coeficiente de determina??o (R?) foi considerado alto ou m?dio em 5 das 6 vari?veis end?genas, assim o modelo consegue explicar 47,3% da varia??o da inten??o comportamental. Ressalta-se que, dentre os antecedentes da inten??o comportamental (BI) analisados no presente estudo, utilidade percebida ? a vari?vel que possui maior efeito sobre a inten??o comportamental, seguida pela facilidade de uso (PEU) e a atitude (AT). Dentre os aspectos organizacionais (fatores cr?ticos de sucesso) estudados, complexidade tecnol?gica (TC) e treinamento (TRE) foram aqueles com maior efeito sobre a inten??o comportamental de usar, apesar desses efeitos serem inferiores aos produzidos pelos fatores comportamentais (origin?rios do TAM). Destaca-se, ainda, que o apoio da alta administra??o (TMS) apresentou, entre todas as vari?veis, o menor efeito sobre a inten??o de usar (BI) e foi seguida pela comunica??o (COM) e coopera??o (CO), as quais exercem um baixo efeito sobre a inten??o comportamental (BI). Portanto, conforme outros estudos, os construtos relativos ao TAM mostraram-se adequados para a presente pesquisa. Dessa maneira, o estudo contribuiu no sentido de demonstrar ind?cios de que o Modelo de Aceita??o da Tecnologia pode ser aplicado ? predi??o da aceita??o de sistemas integrados de gest?o, mesmo em organiza??es p?blicas.
