The thesis is dealing with the concept of Green IT (reffered to, in some of the documents, as the Green ICT) and its relation to the MMDIS methodology. The term Green IT appears in connection to the sustainable development of information systems of organizations and companies. The thesis is dealing with the concept of Green IT (reffered to, in some of the documents, as the Green ICT) and its relation to the MMDIS methodology. The term Green IT appears in connection to the sustainable development of information systems of organizations and companies. The thesis introduction explains this concept, and then describes its historical development, status, metrics, and legislation related to it. Further, the reader is made familiar with the enterprise/company/notsure information systems and their architecture, efficiency and benefits they have for the companies. Furthermore, the thesis deals with the issue of MMDIS, and briefly introduces it to the readers. The next part of the thesis then compares selected countries, Europe, UK and China, in terms of their legislation concerning the environment and Green IT. At the end of this chapter there is a comparison of these countries through the use of the so-called green metrics. The the second to last part of the thesis is then devoted to recherche of different frameworks for the implementation of Green IT into the company, from their analysis I then formulate steps that should help businesses with the implementation of Green IT. The last part assesses the continuity of Green IT on the MMDIS methodology, both in terms of the dimensions, and also in terms of the stages of the application lifecycle.

<p>Fundamental changes have been happening in healthcare organizations and delivery in these decades, including more accessible physician information, the low-cost collection and sharing of clinical records, and decision support systems, among others. Emerging information systems and technologies play a signification role in these transformations. To extend the understanding and the implications of information systems on healthcare, my dissertation investigates the influence of information systems on enhancing healthcare operations. The findings reveal the practical value of digitalization in indicating healthcare providers' cognitive behaviors, responding to healthcare crises, and improving medical performance.</p> <p><br></p> <p>The first essay investigates the unrevealed value of a special type of user-generated content in healthcare operations. In today's social media world, individuals are willing to express themselves on various online platforms. This user-generated content posted online help readers get easy assess to individuals' features, including but not limited to personality traits. To study the impact of physicians' personality traits on medicine behaviours and performance, we take a view from the perspective of user generated content posted by their supplier side as well as using physician statements which have been made available in medical review websites. It has been found that a higher openness score leads to lower mortality rates, reduced lab test costs, shorter time usage in hospitals treated by physicians with greater openness scores. Furthermore, taking these personality traits into consideration in an optimization problem of ED scheduling, the estimation of counterfactual analysis shows an average of 11.4%, 18.4%, and 17.8% reduction in in-hospital mortality rates, lab test expenditures, and lengths of stay, respectively. In future operation of healthcare, physicians' personalities should be taken into account when healthcare resources are insufficient in times of healthcare pandemics like COVID-19, as our study indicates that health service providers personality is an actual influence on clinical quality.</p> <p><br></p> <p>In the second essay, we focus on the influences of the most severe healthcare pandemic in these decades, COVID-19, on digital goods consumption and examine whether digital goods consumption is resilient to an individual’s physical restriction induced by the pandemic. Leveraging the enforced quarantine policy during the COVID-19 pandemic as a quasi-experiment, we identify the influence of a specific factor, quarantine policy, on mobile app consumption in every Apple app store category in the short and long terms. In the perspective of better responding in the post-pandemic era, the quantitative findings provide managerial implications to the app industry as well as the stock market for accurately understanding the long-term impact of a significant intervention, quarantine, in the pandemic. Moreover, by using the conditional exogenous quarantine policy to instrument app users’ daily movement patterns, we are able to further investigate the digital resilience of physical mobility in different app categories and quantify the impact of an individual’s physical mobility on human behavior in app usage. For results, we find that the reduction in 10% of one’s physical mobility (measured in the radius of gyration) leads to a 2.68% increase in general app usage and a 5.44% rise in app usage time dispersion, suggesting practitioners should consider users’ physical mobility in future mobile app design, pricing, and marketing.</p> <p><br></p> <p>In the third essay, we investigate the role of an emerging AI-based clinical treatment method, robot-assisted surgery (RAS), in transforming the healthcare delivery. As an advanced technique to help diminish the human physical and intellectual limitations in surgeries, RAS is expected to but has not been empirically proven to improve clinical performance. In this work, we first investigate the effect of RAS on clinical outcomes, controlling physicians' self-selection behavior in choosing whether or not to use RAS treatment methods. In particular, we focus on the accessibility of RAS and explore how physician and patient heterogeneity affect the adoption of the RAS method, including learning RAS and using RAS. Investigating the decision-making process on RAS implementation in both the learning and using stages, we show the synergy of RAS implementation in alleviating healthcare racial disparity. Ultimately, the mechanism analysis will be conducted to reveal the underlying mechanism that induces the enhancement of surgical outcomes. For instance, the estimations tend to reveal that, more than surging clinical performance, RAS tends to increase standardization in time and steps when applying the treatment procedures. </p>

Im Folgenden wird ein Promotionsprojekt zur Implementierung und Optimierung von hybriden Indexstrukturen beschrieben. Die erhöhte Suchperformance wird bei hybriden Indexstrukturen durch einen höheren Aufwand an Vorberechnungen bei Einfügeoperationen erreicht. Dadurch ergibt sich, im Gegensatz zu Ansätzen, welche mehrere Indexstrukturen miteinander verbinden oder getrennte Suchanfragen ausführen eine Effizienz der Reorganisation hybrider Indexstrukturen, die prohibitiv für den Einsatz in den meisten Anwendungen ist. Diese sollen innerhalb des Promotionsprojekts optimiert werden, um eine Einsatzfähigkeit in realistischen Szenarien gewährleisten zu können.

Purpose: The purpose is to investigate and analyse the impact of intra-organizational purchasing synergy on periodic price adjustment (PPA) process. Specifically, paper provides a view on how  purchasing process synergy through an operational IT platform can increase process reengineering opportunities within PPA.  Methodology: So, to fulfil the purpose of the research, the in-depth case study approach is chosen as a strategy that goes along with exploratory nature of the study, aimed at gaining rich insights in the context in which the phenomenon happens. Findings: The findings emphasize the importance of global process standardization and balanced governance among regional affiliates in successful implementation of PPA process synergy. We also identify a set of specific process reengineering needs  in PPA such as company wide information sharing,  standardization of part specifications and cost bases, and joint world-wide cost reduction activity within global buyer community (BGC). Then it is observed that all these process reengineering initiatives will not be possible without solid and flexible IT infrastructure  to improve buyer productivity and support their further development.   Research limitations/implications: Primarily, this study was conducted on single in-depth case study which makes it difficult to completely generalize the findings. Next, there are many factors impacting intra-organizational pricing processes besides global synergy projects. In fact, regional and organizational contexts are of high importance, which are addressed but not analysed in detail in the current study.   Practical implications: Together, the findings contribute to our understanding of the step-by-step pricing activity from industrial customer perspective and how buyers can improve cost competitiveness through various tangible and commercial part cost reduction activities.   Originality/value: Current study has addressed the pricing process from industrial customer perspective. It has two main theoretical contributions: (1) Detailed step-by-step description of PPA process between OEMs and their suppliers happening after SOP; and (2) groundwork for implementation guidance on intra-organizational price revision process synergy.

THESIS Submitted in fulfilment of the requirements for the degree MAGISTER TECHNOLOGIAE in BUSINESS INFORMATION SYSTEMS in the FACULTY OF BUSINESS INFORMATICS at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY 2006 / E-commerce improves value chain integration, enables customisation and also provides smaller companies opportunity to reach customers worldwide. However e-commerce poses challenges to companies, including how to approach e-commerce to gain competitive advantage. Although a number of studies report on e-commerce adoption, these do not provide clear guidelines to determine how SMMEs should progress or move into e-commerce adoption. The aim of this research study is to examine the various available approaches and propose a model to assist SMMEs to determine how to start e-commerce adoption. Findings from this research study indicate that a small percentage of SMMEs are selling online in the Western Cape and realizing benefits derived from ecommerce adoption. The SMMEs interviewed followed an “adoption ladder” approach to e-commerce adoption, however, some had the perception that with maturity of e-commerce, a “managed strategic” approach would be possible. In conclusion the research study proposes a model to assist SMMEs to progress into e-commerce adoption, illustrating two available approaches.
