À l’instar de plusieurs systèmes de santé, les centres hospitaliers québécois ont amorcé l’informatisation du dossier patient sous forme papier pour la transition vers un dossier clinique informatisé (DCI). Ce changement complexe s’est parfois traduit par des répercussions sur les pratiques de soins, la sécurité et la qualité des soins offerts. L’adoption de la part des utilisateurs de technologies de l’information (TI) est considérée comme un facteur critique de succès pour la réalisation de bénéfices suite au passage à un DCI. Cette étude transversale multicentrique avait pour objectifs d’examiner des facteurs explicatifs de l’adoption, de l’utilisation réelle d’un DCI, de la satisfaction des infirmières et de comparer les résultats au regard du sexe, de l’âge, de l’expérience des infirmières et des stades de déploiement du DCI. Un modèle théorique s’appuyant sur la Théorie unifiée de l’adoption et de l’utilisation de la technologie a été développé et testé auprès d’un échantillon comptant 616 infirmières utilisant un DCI hospitalier dans quatre milieux de soins différents. Plus particulièrement, l’étude a testé 20 hypothèses de recherche s’intéressant aux relations entre huit construits tels la compatibilité du DCI, le sentiment d’auto-efficacité des infirmières, les attentes liées à la performance, celles qui sont liées aux efforts à déployer pour adopter le DCI, l'influence sociale dans l’environnement de travail, les conditions facilitatrices mises de l’avant pour soutenir le changement et ce, relativement à l’utilisation réelle du DCI et la satisfaction des infirmières. Au terme des analyses de modélisation par équations structurelles, 13 hypothèses de recherche ont été confirmées. Les résultats tendent à démontrer qu’un DCI répondant aux attentes des infirmières quant à l’amélioration de leur performance et des efforts à déployer, la présence de conditions facilitatrices dans l’environnement de travail et un DCI compatible avec leur style de travail, leurs pratiques courantes et leurs valeurs sont les facteurs les plus déterminants pour influencer positivement l’utilisation du DCI et leur satisfaction. Les facteurs modélisés ont permis d’expliquer 50,2 % de la variance des attentes liées à la performance, 52,9 % des attentes liées aux efforts, 33,6 % de l’utilisation réelle du DCI et 54,9 % de la satisfaction des infirmières. La forte concordance du modèle testé avec les données de l’échantillon a notamment mis en lumière l’influence des attentes liées à la performance sur l’utilisation réelle du DCI (r = 0,55 p = 0,006) et sur la satisfaction des infirmières (r = 0,27 p = 0,010), des conditions facilitatrices sur les attentes liées aux efforts (r = 0,45 p = 0,009), de la compatibilité du DCI sur les attentes liées à la performance (r = 0,39 p = 0,002) et sur celles qui sont liées aux efforts (r = 0,28 p = 0,009). Les nombreuses hypothèses retenues ont permis de dégager l’importance des effets de médiation captés par le construit des attentes liées à la performance et celui des attentes liées aux efforts requis pour utiliser le DCI. Les comparaisons fondées sur l’âge, l’expérience et le sexe des répondants n’ont décelé aucune différence statistiquement significative quant à l’adoption, l’utilisation réelle du DCI et la satisfaction des infirmières. Par contre, celles qui sont fondées sur les quatre stades de déploiement du DCI ont révélé des différences significatives quant aux relations modélisées. Les résultats indiquent que plus le stade de déploiement du DCI progresse, plus on observe une intensification de certaines relations clés du modèle et une plus forte explication de la variance de la satisfaction des infirmières qui utilisent le DCI. De plus, certains résultats de l’étude divergent des données empiriques produites dans une perspective prédictive de l’adoption des TI. La présente étude tend à démontrer l’applicabilité des modèles et des théories de l’adoption des TI auprès d’infirmières œuvrant en centre hospitalier. Les résultats indiquent qu’un DCI répondant aux attentes liées à la performance des infirmières est le facteur le plus déterminant pour influencer positivement l’utilisation réelle du DCI et leur satisfaction. Pour la gestion du changement, l’étude a relevé des facteurs explicatifs de l’adoption et de l’utilisation d’un DCI. La modélisation a aussi mis en lumière les interrelations qui évoluent en fonction de stades de déploiement différents d’un DCI. Ces résultats pourront orienter les décideurs et les agents de changement quant aux mesures à déployer pour optimiser les bénéfices d’une infostructure entièrement électronique dans les systèmes de santé. / Like many other healthcare systems, healthcare institutions in Quebec are in the process of transitioning from paper-based patient records to Electronic Patient Records (EPRs). For some time now, this considerable and complex transition has had a high failure rate and unexpected consequences on care practices and the quality and safety of the care provided to patients. The acceptance of information technology by users is considered to be a critical success factor in realizing the benefits of EPR implementation. The goal of this multicenter cross-sectional study was to examine the explanatory factors of the adoption and actual use of an EPR by nurses and their satisfaction. It also aimed at comparing the outcomes by gender, age and experience and by EPR adoption stage. To do so, a theoretical model based on the unified theory of acceptance and use of technology (UTAUT) was developed and tested on a sample of 616 nurses who use an EPR in four different acute care facilities. Specifically, the study tested 20 research hypotheses on the relationships among eight different constructs, namely EPR compatibility, self-efficacy, performance expectancy, effort expectancy, social influence, facilitating conditions explaining the actual use of an EPR by nurses and their satisfaction. Fifteen research hypotheses were supported following structural equation modeling analysis. The results revealed that performance expectancy, effort expectancy, facilitating conditions and compatibility of the EPR (with preferred work style, existing work practices and values of nurses) were strong determinants of the actual use of an EPR by nurses and their satisfaction. The variables explained 50.2% of the variance of performance expectancy, 52.9% of effort expectancy, 33.6% of actual use of an EPR by nurses and 54.9% of their satisfaction. The strong fit of the model tested with the sample data showed the influence of performance expectancy on the actual use of the EPR by nurses (r = .55 p = .006) and on their satisfaction (r = .27 p = .010), the influence of the facilitating conditions on effort expectancy (r = .45 p = .009), EPR compatibility on performance expectancy (r = .39 p = .002) and on effort expectancy (r = .28 p = .009). The numerous hypotheses supported highlight the importance of the mediation effects captured by the performance expectancy and effort expectancy constructs. Comparisons based on age, experience and gender of the respondents did not reveal any statistically significant differences in terms of the acceptance and actual use of an EPR by nurses and their satisfaction. However, those based on the four EPR adoption stages revealed significant differences in terms of the relationships modelled. The results suggest that certain key relationships become more intense as the EPR adoption stages progress, thereby providing a better explanation of the variance in the satisfaction of nurses. Some results of the study also differ from the empirical data produced in a predictive perspective of information technology adoption. The study shows the applicability of the technology acceptance models and theories for nurses working in hospital centres. The results suggest that an EPR that meets performance expectancies is the most determining factor in positively influencing the actual use of the EPR and the satisfaction of nurses. To manage change, the study identified some explanatory factors of the acceptance and use of an EPR, and the model testing revealed how the relationships evolve based on the various EPR adoption stages. The results could help guide decision makers and change agents in determining the measures to implement in order to maximize the benefits of a fully electronic infostructure in healthcare systems.

Osborne & Gaebler在所著的「新政府運動」(Reinventing Government)一書中，曾引述戴明(W. D. Deming)博士所倡導的「全面品質管理」(Total Quality Management)概念指出：員工的參與才能有效的解決問題，因為員工最了解制度，而且最清楚癥結所在。這樣的提示，雖早被管理者重視且廣泛地運用在組織活動的設計範疇中，不過，就參與效能的評估與改善，仍有不少值得再予強調的課題。本研究既係依此觀點，藉由檢視使用者參與行政管理資訊系統發展過程之現象，提供一個思索的空間。 　　整體研究架構，以檢證Davis所提出的技術接受性模式為基準，同時透過此一模式了解使用者參與在系統使用行為上造成模糊結果的原因，進而提醒行政管理者，在系統發展或執行過程，勿陷入以效率掛帥的功能主義典範窠臼，對於溝通、平等與尊重等新人性主義典範所揭示的概念應予適度關注。也就是說，在民主的工作環境下，應將本身視為組織生活的目的，而非僅有工具性價值；參與效能的評估不僅須針對「結果」而且應顧及「過程」。 　　在上述要旨下，關於研究實體部分，經就文獻分析、實證調查結果的發現與筆者實務經驗，提出以下結論與建議： 　　（一）技術接受性模式，尚可適度詮釋國內行政管理資訊系統使用者的使用行為。惟其適用的分析情境、態度與行為關係之假定，仍有再作深入探究之必要。 　　（二）參與及系統使用行為關係之研究，不僅可透過置入中介變項的權變研究觀點來了解，分析使用者在這二行為間的心理歷程，對於改善參與效能而言，亦是一種可行的途徑。 　　（三）使用者對系統有用性及簡易性的認知，是影響系統使用態度、意向及行為的二大要素。其中有用性的認知更具決定性地位。 　　（四）使用者參與效能的模糊結果，除了源於理論欠紮實、研究模式過於簡化，以及研究方法上的瑕疵以外，研究上未仔細區辨系統使用情境之差異亦為主因。不過，參與究非萬靈丹，無定論的結果，並不代表即是一種錯誤。 　　（五）參與效能的改善，除了管理當局的支持與專家協助以外，有賴從加強系統發展者與使用者的教育訓練著手。 　　（六）自主性的系統使用情境下，使用行為（頻率）始能較正確地詮釋使用者接受程度。 　　（七）未來應重視以系統發展者與使用者互動作為分析單元的研究。 　　至於在行政管理實務上，本研究所欲表達的主要意念是：員工的參與及評估的步驟是缺一不可的。因為，沒有評估的參與，則參與無法發揮實際的效果，充其量僅具象徵性的價值；而僅有評估卻無參與活動，這樣的評估除了可能是膚淺、不切實際以外，在實務上存在的機率亦不大。公部門的決策及管理階層，面對高度層級節制的組織文化，能否擺脫「官大學問大」心態，而以恢宏的胸襟與氣度，善用與因應來自員工的意見，塑造具有參與效能的情境，將是成功地推展各項事務最基本的前提要件。

本研究以科技接受模型為基礎，企圖整合資訊品質、系統品質和網站服務品質作為認知有用性和認知易用性的前置變項，期待了解三種品質構面對科技接受模型的影響效果，藉以探討民眾在使用電子化政府入口網時，會受到何種網站品質的影響，增加其使用意圖，以獲得對電子化治理的相關理解。另外本研究並嘗試以形成性指標的方式建構三種品質構面，以修正過去文獻誤用品質構面為反映性指標的情形。 透過線上問卷系統*蒐集1459位民眾的意見後，本文的研究結果顯示對認知易用性影響最大者為網站服務品質，認知有用性則受到認知易用性最大影響。對使用意圖有最大影響者為使用者的態度。三種品質的形成性指標對品質構面皆可達到顯著，在解釋上較為符合品質構面應為形成性指標的建構形式。文後並提供了對政府建置政府網站的實務建議，希冀能夠對未來政府網站建置提供參考。 / Based on technology acceptance model(TAM), this study develops a reaserach model that integrate information quality, system quality and website service quality as antecedents of perceived usefulness and perceived ease of use. The purpose of study is to explore how the three quality might influence technology acceptance model, and what might strengthen user intention on e-government portal website. In addition, this study develops quality constructs as “formative-indicators”rather than reflective ones to correct the misuse of some literatures. The model is then tested using a sample of 1459 users from online survey and analyzed the data using structural equation modeling. The results show that(1) website service quality(WSQ) have the most effects on ease of use(EOU), and that (2)ease of use have the most effects on usefulness(PU). They also demonstrate that (3)attitude predit user intention the most. The significance illustrate logically the relation between formative-indicators of three quality and the constructs. Implications of this study for research and practice are presented.

數位遊戲已成為探討現代生活科技中一項重要的領域。智慧型手機，為近兩年興起的行動平台載具，根據資策會資料顯示，在手機進行娛樂活動應用程式的排行，第一為聽音樂，第二即為進行遊戲。觀察智慧型手機上的應用程式市集(如：android market、app store)，使用者可以快速方便的利用網路下載遊戲，在眾多遊戲中，使用者選擇何種類型遊戲下載並進行遊戲，對遊戲開發商非常重要。在智慧型手機上結合許多科技技術(如：無線網路、各式感測器......等)，皆有可能影響使用者進行遊戲和選擇遊戲的動機。因此，了解並且針對使用者需求與使用者行為設計遊戲，在數位內容領域進行數位遊戲研究與開發是重要的議題。 為了解使用者在智慧型手機上進行遊戲的動機，本研究使用科技接受模型和動機理論探討使用者的內在動機和外在動機，透過問卷分析初步了解使用者在智慧型手機上進行遊戲的原因，以及在智慧型手機上擷取使用者在手機上進行遊戲的行為和訪談使用者進行遊戲的因子，將兩資料進行比對驗證，找出使用者在智慧型手機上進行遊戲的模型，以及外在和內在動機之相互影響，作為未來規劃與策略發展方向的參考依據。 根據資料分析發現，使用者進行遊戲的動機會受到遊戲的操作性和在遊戲中得到的樂趣影響。並且使用者會因為他人推薦或看到他人進行遊戲，影響到使用者進行遊戲的意願，而使用者在進行遊戲時，遊戲中提供與他人互動的功能也能激發使用者進行遊戲。此外，在智慧型手機遊戲情境中，使用者會受到外在動機影響，改變本身對遊戲的觀點，影響到使用者的內在動機，進而改變使用者對遊戲的意願。 / Digital games have become an important domain of exploration the technology of modern life. The smartphone which is a mobile device rises due two years. Follow the MIC data of entertainment applications on mobile phone rank, the first is listening music and the second is playing games. User can easy download games quickly by wireless from application market like Android market or app store. It is important for game developers to know which game user chooses and downloads in large games. The smartphone combine different technology and sensors that may influence user’s motivations to choose games and play games. Therefore, to understand user’s need and user’s behavior for game design which is important discuss for digital game study and developer of digital content domain. To understand the motivations of user playing games on the smartphone, so this study uses technology acceptance model (TAM) to explore intrinsic motivations and extrinsic motivations of playing game. Through questionnaire to find the factors that user plays games on smartphone, and we also collect users’ behavior from smartphone and interview users. The study combines these data to find the model of user playing game on the smartphone, and the relationship between intrinsic motivations and extrinsic motivations. The study finds that perceived ease of use and the fun in games effect user’s motivation. The user intention influenced by people who around user and also affected in the game which provide user to interact with others. By the way, user’s extrinsic motivations affect intrinsic motivations on smartphone context, and change the mind of playing games.

<p>No organisation has an endless and unlimited supply of money, especially in a recessive economy, and therefore decisions have to be made as to which areas an organisation will invest in. As organisations, such as YZ1 financial services organisation, are focused on seeing returns on investment (ROI), implementing software that is not being used&nbsp / will not render any benefits to the organisation. Research problem: Project Managers (PMs) in YZ organisation&rsquo / s IT department need to perform mandated processes, as&nbsp / defined in their centralised repository. PMs need to use Financial and Planning Software (FPS)2 software to perform certain project management activities, as required by their&nbsp / job function. However, it was found that MPP3 software, another tool, was used for more detailed project schedules, as well as activities that were not strictly enforced by&nbsp / management, the Project Office or the Quality Assurance team. Therefore, from this discovery, it was not clear whether the intended benefit of implementing this mandatory&nbsp / software (FPS) was being realised &ndash / since implementing software that is not being utilised fully would not deliver the intended benefits to the IT department (Devaraj &amp / Kohli&nbsp / 2003), even if the software is termed &lsquo / mandatory&rsquo / . Objective: The primary objective of this research was to explore and optimise the key success factors for an effective&nbsp / implementation of mandatory software in a department, in order to derive the intended business benefits. Literature Review: Literature was reviewed in the search for models or&nbsp / theories that explore the relationship between the use of mandatory software and the achievement of business benefits. The Information Management Body of Knowledge&nbsp / (IMBOK) was selected as this framework defines the relationship between IT and the realisation of business benefits, and ultimately the achievement of any business strategy.

A model was compiled using unique constructs in the Technology Acceptance Model&nbsp / (and TAM2), the Motivational Model (MM) and the Model of PC Utilisation (MPCU) &ndash / in order to test user acceptance of mandatory software. The literature study concludes with a&nbsp / review of an approach to benefits management including five stages, namely: identifying and structuring benefits, planning for the realisation of benefits, executing the plan, in&nbsp / addition to the evaluation and the review.

Findings: The main finding, based on the compilation of three models of user acceptance, proved that FPS was not being utilised&nbsp / as intended. There was also no evidence of an improvement in business operations. Therefore, benefits management was negatively impacted. Organisational processes were&nbsp / dentified as the most important organisational factor, influencing the usage of FPS software.

This study aimed to understand the relationship between mobile device screen display size (laptops and smartphones) and text segmentation (continuous text, medium text segments, and small text segments) on learning outcomes, cognitive load, and user perception. This quantitative study occurred during the spring semester of 2015. Seven hundred and seventy-one chemistry students from a higher education university completed one of nine treatments in this 3x3 research design. Data collection took place over four class periods. The study revealed that learning outcomes were not affected by the mobile screen display size or orientation, nor was working memory. However, user perception was affected by the screen display size of the device, and results indicated that participants in the sample felt laptop screens were more acceptable for accessing the digital chemistry text than smartphone screens by a small margin. The study also found that neither learning outcomes, nor working memory was affected by the text segmentation viewed. Though user perception was generally not affected by text segmentation, the study found that for perceived ease of use, participants felt medium text segments were easier to learn from than either continuous or small test segments by a small margin. No interaction affects were found between mobile devices and text segmentation. These findings challenge the findings of some earlier studies that laptops may be better for learning than smartphones because of screen size, landscape orientation is better for learning than portrait orientation in small screen mobile devices, and meaningful text segments may be better for learning than non-meaningful, non-segmented, or overly segmented text. The results of this study suggest that customizing the design to the smartphone screen (as opposed to a one-size-fits-all approach) improves learning from smartphones, making them equal to learning from laptops in terms of learning outcomes and cognitive load, and in some cases, user perspective. / text

The phenomenon of business value dissipation in mature organisations as an unintended by-product of the adoption and use of information systems has been a highly debated topic in the corporate boardroom awakening the interest of practitioners and academics alike. Much of the discourse tends to focus on the inability of organisations to unlock and realise the intended benefits to be harvested through large information systems investments. While the business case for investing in large technology programmes has been thoroughly investigated, the human agent that causes value erosion through his interaction with information systems (IS), has not received the studied attention it deserves. This study examines the use of technology in organisations by considering the dichotomy inherent in IS where its introduction for the purposes of creating new or sustaining existing business value subsequently also inadvertently dissipates value. The study proceeds to investigate the root people-induced causes resulting in the unintentional dissipation of value and presents an empirically validated model suggesting that human agents do not only create value for organisations through their use of IS, but at the same time, deliberately or inadvertently, dissipate value. The root people-induced causes resulting in the unintentional dissipation of value is delineated within a Theoretical Technology Value Framework that is constructed from a review of the extant literature, and delineates the overall unintentional value destroying causes and effects of IS on organisations. The Theoretical Technology Value Framework is forthwith applied as a basis for the development of a set of questions to support both qualitative and quantitative investigations from which an Archetypical Technology Value Model was derived. Finally, an Archetypical Technology Value Model is presented as a benchmark and basis to identify, investigate, mitigate and minimise or eliminate the unintentional value destroying effects of IS on Information Technology driven organisations. The study concludes with implications for both theory and practice and suggestions on how value erosion through the activities of the human agent may be identified, modeled and mitigated. Ultimately, recommendations are offered towards the crafting of more effective IS. / School of Computing / Ph. D. (Information Systems)
