This study, the effects of computer simulations on the teaching and learning of Atomic Combinations was carried out in the Tshwane North District of Gauteng Province in South Africa. The study employed a non-randomized control-group pre-test and post-test quasi-experimental design involving two grade 11 Physical Science classes; one as an experimental (52) and the other as a control group (53). An Achievement Test consisting of 30 multiple-choice questions and a Structured Questionnaire designed for teacher and learner participants were the principal data collection tools used. The questionnaire was developed to answer research questions two and three that guided this study. The questionnaire tested how much learners and teachers were familiar with the use of computers and if there were any hindrances to computer usage. The achievement test instrument was administered as a pre-test and post-test to answer research question one. The experimental group received computer-assisted teaching and the control group was taught using traditional teaching method (lecture) on the same topics. The intervention took two and a half weeks for each of the schools involved in the study. Analyses of scores of the two groups in post-test were compared using Statistical Package for the Social Sciences (SPSS) independent t-test version 16.0. The results showed that t = 0.467, df = 103, p = 0.048 and the Sig. (2-tailed) value is 0.641. Since sig. (2-tailed) value is greater than 0.05, it can be concluded that there is no statistical significant difference between the experimental group and the control group. / Science and Technology Education / M.

The fact is that every individual leaves behind vast amounts of data, companies collect this data and use the knowledge gained from it in a variety of ways. One area that is lucrative for the use of Big data is the financial sector. A prominent example of the use of Big data is real-time stock market insights. However, there are still industries in which Big data is not yet used for various reasons. One of these industries is the tax consulting sector, which will be the focus of this research. With its high entry hurdles, direct dependence on the legislator, and the associated atypical data sets, the tax consulting sector represents a special use case within the financial sector.   Because big data has not been used in the tax consulting sector yet and that the setting is atypical compared to other sectors, a closer analysis of potential influences on services, the working environment, and quality is of particular interest here. This analysis is the core of this study and was carried out using an interpretative qualitative approach in the form of a case study. In this case study, the three most important stakeholders of Austrian tax consultancies- employers, employees, and clients - were interviewed on the one hand through interviews and on the other hand through a survey with open-ended questions. The results were then compared in the discussion with the changes that studies in other fields have identified.   The results of the study showed that the stakeholders predominantly assume that the quality of services will improve significantly through the use of big data, especially in accounting and business management services. Stakeholders also predicted a positive development concerning the range of services offered. It was also predicted that the range of services offered could increase on the one hand and that services of a business management nature could benefit enormously on the other. In the area of the working environment, employees said that increased training activity and process adaptation would be the only significant changes. In the area of risks, all three stakeholder groups agreed and mentioned data protection. Interesting differences between the three stakeholder groups were on the one hand that the employers gave very detailed answers, which allows the assumption that they have already thought carefully about the topic of big data. On the other hand, in contrast to the other two groups, the employees did not primarily think of their area (work environment) in the analysis, but of that of the clients and thus of the provision of the service. This underlines the strong focus on client satisfaction and encourages a more intensive involvement in the design process.   In contrast to other studies, this thesis analyses the influences on the areas not from a retrospective point of view, but a prospective point of view. This approach allows an unbiased look at the opinions of stakeholders and thus provides the best possible information for the design of big data tools for the tax consulting sector. Besides, by comparing this with changes found in other studies, it is possible to estimate how the use of big data in the tax consulting sector differs from other sectors.

Date: June 1st, 2022  Level: Bachelor/masters thesis, Business Economics, 15 hp  Institution: EST – Economy, Society & Technology, Mälardalens University  Authors: Linnea Jibbefors, 1999-06-17, David Ohrlander, 1997-08-10.  Title: THE BEST IS YET TO COME - A qualitative study of Hybrid Leadership  Supervisor: Magnus Hoppe Keywords: Digital leadership, leadership, teleworking, communication, information- and communication technology, digital communication, global teams, virtual teams, hybrid leadership and hybrid work. Research questions:  ●        How does hybrid leadership apply in practice?  ➢     What are the most apparent possibilities and challenges between workplace leadership and digital leadership?  ➢     How is the leadership affected in regards to clarity, trust, technology and teams, related to hybrid leadership? Purpose: The authors of this study aims to investigate how the phenomenon of hybrid leadership, leadership that occurs both at physical workplaces and digital workplaces, appears in practice. Method: In this study a qualitative research method has been applied where the empirical data has been gathered through semi structured interviews. The theoretical framework was the foundation for the interview questions and a total of 13 interviews were conducted. Thereafter the empirical material was analyzed through the theoretical framework, which led to the answering of the purpose and the research questions. Conclusion: Hybrid leadership has contributed to multiple possibilities and challenges for organizations. The most apparent possibility is for workers to conduct their work both from home and digitally, which contributes to efficiency since the workers can accomplish work rather than traveling. The respondents have stated that this is the future of working. Hybrid leadership consists of four important ground stones: Clarity, Trust, Technology and Team. The hybrid leader must communicate a clear objective, maintain an open and continuous two-way communication, contribute to as high a social presence as possible and promote team dynamics on the digital platform. To do this, the hybrid leader must have an increased focus on the workers social satisfaction and well-being through the digital platforms, by using cameras and conducting one-to-one-meetings regularly. / Datum: 2022-06-01  Nivå: C-uppsats, Företagsekonomi, 15 hp  Akademi: Akademin för Ekonomi, Samhälle och Teknik, Mälardalens Universitet   Författare: Linnea Jibbefors, 1999-06-17, David Ohrlander, 1997-08-10 Titel: DET BÄSTA HAR INTE HÄNT ÄN - En kvalitativ studie av hybridledarskap  Handledare: Magnus Hoppe  Nyckelord: Digitalt ledarskap, ledarskap, distansarbete, kommunikation, informations- och kommunikationsteknik, digital kommunikation, globala teams, virtuella teams, hybridledarskap och hybridarbete.  Forskningsfrågor:  ●        Hur tillämpas ett hybridledarskap?  ➢     Vilka är de mest framträdande möjligheterna och utmaningarna mellan arbetsplatsförlagt ledarskap och digitalt ledarskap? ➢     Hur påverkas ledarskapets tydlighet, tillit, teknik och team vid ett hybridledarskap? Syfte: Studiens syfte är att undersöka hur fenomenet hybridledarskap, ledarskap som äger rum både vid arbetsplatsförlagt och digitalt arbete, framträder i praktiken. Metod: I denna studie har en kvalitativ forskningsmetod använts där den empiriska datan samlats in genom semistrukturerade intervjuer. Den teoretiska referensramen la grunden för intervjufrågorna och totalt genomfördes 13 intervjuer. Därefter analyserades det empiriska materialet med stöd från teorin, vilket resulterade i att syftet och forskningsfrågorna kunde besvaras.  Slutsats: Hybridledarskapet har bidragit till en rad möjligheter och utmaningar för organisationer. De främsta möjligheterna innefattar att medarbetarna kan arbeta hemifrån eller på plats, vilket bidrar till effektivitet, då tiden kan användas till arbetsuppgifterna istället för att resa. Respondenterna menar att detta är framtidens sätt att arbeta för organisationer. Hybridledarskapet bör hantera fyra viktiga beståndsdelar; Tydlighet, Tillit, Teknik och Team. Hybridledaren måste kommunicera ut en tydlig målbild, upprätthålla en öppen och kontinuerlig tvåvägskommunikation, bidra till hög social närvaro samt främja gruppdynamiken på den digitala plattformen. För att göra detta bör hybridledaren ha ett ökat fokus på medarbetarnas sociala tillfredsställelse och välmående via de digitala plattformarna, genom användandet av kamera och regelbundna one-to-one–möten.

Information and communication technology (ICT) is playing an important role in modern society, contributing to economic growth and affecting society and people’s lifestyles. There are high expectations on ICT to contribute to sustainable development, e.g. through greenhouse gas emissions reductions. ICT solutions (ICT products and services) are often perceived as having low or no environmental impacts compared with conventional alternatives. In order to determine the potential of ICT to reduce environmental impacts, environmental assessments of ICT solutions compared with other alternatives are needed. A number of studies have already assessed the environmental impacts of individual ICT solutions and the ICT sector. However, more research is needed, covering different types of impacts (primary, secondary, rebound, etc.) in a variety of impact categories (e.g. climate change, ozone depletion, eutrophication, human and ecotoxicity, etc.). The findings then need to be systematised in order to identify hot-spots and draw generic conclusions. As the area is rather new and fast-developing, assessment methods need to be critically appraised in order to identify challenges and developments necessary for high quality assessments. This thesis aims to contribute to the knowledge on the direct life cycle environmental impacts of ICT solutions and to investigate and analyse the challenges of applying Life Cycle Assessment (LCA) as a tool for environmental assessment of ICT solutions. Two research questions: “What life cycle environmental impacts and their causes can be identified for ICT solutions?” and “What are the methodological challenges of assessing the ICT solutions using LCA?” were analysed by reviewing published LCAs on ICT solutions and conducting a case study of online and printed newspapers. The literature review helped identify hotspots in the life cycle of ICT solutions, draw generic conclusions concerning environmental impacts and their causes, and identify major challenges to LCA application. The case study assessed the environmental impacts of traditional and new media solutions and provided information on methodological challenges. The results show that impacts other than climate change potential and energy use are not well-studied in the ICT sector, creating a risk of possible sub-optimisation and problem shifting. Manufacturing and the use phase are concluded to be the most environmentally intense life cycle stages of ICT products in many studies. However, transportation and end-of-life treatment should not be omitted in the assessments, although their impacts appear lower, as uncertainty and lack of data might be a reason for underestimations. As ICT is under constant and rapid development, environmental assessment of ICT solutions faces challenges regarding e.g. data quality and availability; choice of data type; methodological choices (e.g. choice of functional unit, scope definition and allocation); and assumptions on user behaviour. These affect the final results and thus need to be carefully considered by LCA practitioners. The outcomes of this thesis can benefit practitioners and decision-makers, improving knowledge on the environmental impacts of ICT solutions and challenges in applying LCA for assessment of ICT solutions, and providing improved grounds for more informed decision-making. Areas for further research regarding methodology development and filling knowledge gaps are also identified. / Informations-och kommunikationsteknik (IKT) spelar en viktig roll i dagens samhälle genom att bidra till ekonomisk tillväxt, påverka samhällstrukturer och människors livsstil. Det finns höga förväntningar på att IKT skulle kunna bidra till hållbar utveckling, bland annat genom minskade utsläpp av växthusgaser. Miljöpåverkan från IKT-lösningar (produkter och tjänster) anses ofta vara obefintlig eller mycket lägre än konventionella alternativ. Men för att uppskatta vilken potential IKT har för att minska miljöpåverkan, behöver miljöbedömningar göras. Ett flertal studier har också genomförts för att bedöma miljöpåverkan av specifika IKT-lösningar och av branschen i sin helhet. Fortfarande behövs mer forskning som ger ökad kunskap om olika typer av påverkan (direkt, indirekt, rebound, etc.) och om olika slags miljöeffekter (t.ex. övergödning, toxiska effekter, markanvändning och biodiversitet. De resultat som redan finns kan också sammanställas för att identifiera de betydande aspekterna och för att dra generella slutsatser. Eftersom miljöbedömning av IKT-lösningar är relativt nytt och eftersom sektorn och dess produkter och tjänster utvecklas snabbt behöver metodiken analyseras, diskuteras och vidareutvecklas. Avhandlingens syfte är att bidra med ökad kunskap om IKT-lösningars direkta miljöpåverkan sett ur ett livscykelperspektiv, samt att identifiera och diskutera olika utmaningar med att använda livscykelanalys (LCA) som verktyg för miljöbedömning av IKT-lösningar. Två forskningsfrågor besvaras: ”Vilken miljöpåverkan har IKT-lösningar, sett ur ett livscykelperspektiv, och vad orsakar denna påverkan?” samt ”Vilka är de metodmässiga utmaningarna vid bedömningar av IKT -lösningar med hjälp av LCA?”. Genom en litteraturstudie över livscykelanalyser av IKT-lösningar identifieras betydande aspekter och generella slutsatser gällande miljöpåverkan och dess orsaker dras. Dessutom identifieras och diskuteras metodik-utmaningar. En fallstudie av online- och tryckta tidningar exemplifierar miljöpåverkan från traditionella och nya medielösningar med IKT, och ger dessutom underlag för diskussion om metodmässiga utmaningar. Avhandlingen visar att annan miljöpåverkan än klimatpåverkan och energianvändning inte är särskilt väl studerade inom IKT-sektorn. Detta kan leda till suboptimering och att problem överförs från en typ av miljöpåverkan till en annan. Generellt gäller att det är i tillverknings- och användningsfaserna som den största miljöpåverkan uppkommer. Transporter och avfallshantering visar inte särskilt hög miljöpåverkan i de studier som utförts och sammanställts. Transporter och avfallshantering bör ändå fortsatt inkluderas vid miljöbedömning av IKT-lösningar, eftersom osäkerhet och brist på data kan vara en orsak till resultaten. Eftersom IKT är under ständig och snabb utveckling kommer det fortsatt att vara en utmaning att göra miljöbedömningar av IKT-lösningar. Datakvalitet och -tillgänglighet, typ av data, olika metodval såsom val av funktionell enhet, systemgränser och allokering samt antaganden om användarnas beteende påverkar de slutliga resultaten och måste övervägas noga under en livscykelanalys. Resultaten från avhandlingen kan vara till nytta både för praktiker och för beslutsfattare. De kan bidra till ökad kunskap om miljöpåverkan från IKT-lösningar och utmaningar när det gäller att använda LCA på detta område och ger därmed en bättre grund för mer välunderbyggda beslut kopplade till IKT lösningar. Avhandlingen identifierar även områden för vidare forskning om metodutveckling. / Информационно-коммуникационные технологии (ИКТ) играют важную роль в современном обществе, внося свой вклад в экономический рост и оказывая влияние на общество и стиль жизни людей. Большие надежды возлагаются на вклад ИКТ в устойчивое развитие, например,  посредством уменьшения выбросов парниковых газов. Часто предполагается, что ИКТ решения имеют меньшее негативное воздействие на окружающую среду (ВОС) по сравнению с традиционными решениями, или не имеют его вообще. Для того, чтобы определить потенциал ИКТ в уменьшении ВОС, необходима оценка воздействия на окружающую среду ИКТ по сравнению с другими альтернативами. Уже опубликовано довольно большое количество работ, оценивающих ВОС отдельных ИКТ и ИКТ сектора в целом.  Не смотря на это, необходимо больше исследований, охватывающих различные виды воздействий (первичные, вторичные, т.д.) в различных категориях (например, изменение климата, разрушение озонового слоя, токсичность и т.д.). Затем результаты необходимо систематизировать для того, чтобы определить так называемые «проблемные  точки» и сделать общие выводы. Поскольку эта сфера довольно нова и развивается быстро, методы анализа также необходимо подвергнуть критической оценке для того, чтобы определить возможные трудности, а также усовершенствования, необходимые для проведения последующих анализов высокого качества. Цель этой работы - пополнить базу знаний о воздействии на окружающую среду жизненного цикла ИКТ, а также изучить и проанализировать трудности, возникающие при применении Оценки Жизненного Цикла (ОЖЦ) как метода анализа ИКТ решений относительно их экологического воздействия.  Два вопроса были изучены в этой работе: «Каково воздействие на окружающую среду жизненного цикла ИКТ решений и каковы его причины?» и «Каковы методологические трудности в оценке ИКТ решений с использованием ОЖЦ?».  Для того, чтобы ответить на эти вопросы был сделан обзор опубликованых работ по ОЖЦ ИКТ решений, а также проведена ОЖЦ  интернет газет и их печатных аналогов.  Обзор опубликованных работ помог определить  «проблемные  точки» в жизненном цикле ИКТ решений, сделать общие выводы касательно ВОС и его причин, а также определить главные трудности в применении ОЖЦ. При проведении ОЖЦ  интернет газет и их печатных аналогов было оценено ВОС традиционных и новых видов медиа решений и собрана информация о методологических трудностях. Результаты показали что различные виды экологического воздействия ИКТ сектора (кроме влияния на изменение климата или энергопотребления) мало изучены, что создает риск возможной суб-оптимизации и переноса проблем из одной сферы в другую. Производство и фаза использования во многих исследованиях были выявлены как стадии жизненного цикла, имеющие наибольшее экологическое воздействие. Однако, нельзя пренебрегать такими стадиями жизненного цикла, как транспортировка и утилизация отходов, даже если их ВОС кажется небольшим, т.к. это может быть обусловлено недостатком данных для оценки. Поскольку ИКТ быстро развивается, при оценке экологического воздействия ИКТ решений легко столкнуться с трудностями касающимися, например, качества данных и их доступности; выбора типа данных; методологических решений (выбор функциональной единицы, определение границ исследования, т.д.); предположений по поводу поведения пользователя. Все это влияет на окончательные результаты и поэтому должно быть учтено ОЖЦ специалистами. Результаты этой работы вносят вклад в усовершенствование знаний об экологическом воздействии ИКТ решений и трудностях применения ОЖЦ для анализа ИКТ решений, а также предоставляют улучшенную базу для более информированного принятия решений, а следовально могут быть полезны практикующим исследователям и лицам, ответственным за принятие решений. В работе так же обозначены направления дальнейших исследований: изучение методологии, пополнение недостающих знаний.

Poor health care delivery in rural communities is a major problem facing the health sector in Namibia. Patients who visit rural communities often wait on queues for several hours every day before they can be examined by a medical practitioner. This is detrimental to the health care process and impacts negatively on the efficiency and effectiveness of the sector. Mobile phones can however be employed as tools to improve work processes in such hospitals and as a result improve health care delivery in rural communities. The purpose of this study was to investigate the health care services provided to patients at Outpatient Departments (OPDs) in rural hospitals through the use of data collection instruments such as interviews, questionnaires, document analysis, expert validation and photographs in order to compile a Mobile Health Service Framework (MHSF) to improve healthcare delivery processes in OPDs. From an interpretive paradigm perspective, the qualitative design was used together with a case study approach. Three hospitals in rural communities were used as case studies. These were Okuryangava Hospital, Katutura Hospital and Khomasdal Hospital. Interviews were conducted and questionnaires distributed to the participants. The findings revealed that there is a high concentration of mobile phone usage in rural communities and there is a high usage of the SMS feature on such mobile phones. / Computing / M. Sc.

In the presented dissertation, there is, based on a given topic “Internet tools for lifelong learning in the IT sector”, expressed an appropriate coverage of created partial research tasks with an active solution of them at the Faculty of Business and Management, Brno University of Technology for branch Company Management and Economics, and that in accordance with the defined areas of research and publication activities. For systemic approach to the whole dissertation, it was defined area of theoretical perspectives and expressed methodology for addressing systemic models of education on Internet means and for that practical research work was chosen adaptable (“learning”) Company 1 as a reference (for solving individual practical research tasks) and a methodology of modern approach to modelling was created (“for modern management and information communication between systems”) and also modelling of a required adaptable (“directly also improving with modelling”) Internet (and intranet) environment of companies and its use in the process of lifelong learning of knowledge workers (“teachers”) of Company 1 and possible additional (“knowledge workers and users”) Company 2, 3, ..., m i.e. “businesses as other customers” and all that to actively create an adaptable and new space with the possible use of an evolutionary (“new and also modern and intelligent and self-learning”) means of information and communication technologies (ICT) both from the world and from the Czech Republic and especially new (and evolutionary perspective) Internet tools and resources for business management, lifelong learning in IT sector and necessary monitoring of demanded company's competitiveness operating in dynamically developing IT. By systemically solved modelling on computers, there is expressed an issue of appropriately selected internet tools in a competitive environment of companies, and also there is addressed by computer modelling a new approach to modelling leading to an anticipated modernization of modern electronic lifelong learning forms built on tools and resources of the Internet. The work also includes a creation of models on PCs allowing comparison of expected changes in competitiveness of companies reacting to the benefits of created methodology and that leads to an anticipated improvement in the quality of management and economics of companies in terms of relative improvement of their competitiveness. Solving of these modern issues is conducted based on an appropriate analysis of selected enterprises, corresponding to the solved topic and solved objectives of the work and also obtained information from publications in world information sources on the Internet and from virtual libraries of the world, publishing, seminars, proceedings and conferences. The results of system analytical approach to solving tasks and activities of the research work have been regularly published in articles of professional and peer-reviewed journals and also in conference contributions. In these research results, there is systematically expressed a new essence of solving interface of social and IT technical system with selected resources of internet tools for lifelong learning companies working in IT sector as a possible contribution into modern creation of self-learning organizations.

This study investigates the use of telecentres for educational purposes in telecommunications under-serviced regions of South Africa. The problem addressed by this research has both equity and efficiency aspects. In particular, the thesis examines the impact of telecentres on the formal and non-formal education outcomes of recipient communities - four telecentres, two in townships and two in rural areas. The urban telecentres are Siyabonga in Orange Farm near Johannesburg and Mamelodi Communication and Information Services (MACIS), in Mamelodi township, near Pretoria in Gauteng Province. The rural telecentres are Tombo near Port St Johns in the Eastern Cape Province and Hoxani near Bushbuckridge on the Mpumalanga-Limpopo Province border. The main aim of the research is to conduct a quantitative survey of the telecentre users’ use of telecentres in the above mentioned locations. On the basis of this, the thesis seeks to come to some conclusions about the use and effectiveness of the South African telecentre program. The quantitative analysis of users is supported by a qualitative report and analysis of data gathered through personal interviews of telecentre operators and employees. The thesis reports on the outputs of the centres, limitations in their function, inhibitors to their economic performance, and recommendations for improving their operations. Some of the findings are that telecentres established through public-private partnership (PPP) funding are more effective and successful, computer literacy is a major resource offered, Hoxani telecentre offers outcomes-based education management skills training for local teachers, while Tombo, MACIS and Siyabonga telecentres offer additional business and electronic courses. The thesis also reviews the South African telecentre program against the background of similar programs in selected Asian and Latin American countries, Australia, Canada, and Europe and against the background of an analysis of South African post-apartheid telecommunications sector reforms (1996 to 2007). Insights into the unique nature of challenges facing geographically located telecentres as well as a new model for understanding telecentre operations in South Africa are offered. / Communication Science / D.Litt. et Phil.(Communication Science)

The introduction of e-learning in teaching and learning has necessitated the training of staff members in Information and Communication Technology (ICT). This study focuses on the challenges that staff members, who are the facilitators of learning, experience when undergoing training in ICT. The research design employed a qualitative methodology which involved focus groups from a public university. Data was collected from the participants through semi-structured interviews. The findings indicate that the challenges that staff members experienced during ICT training are related to a lack of computer competence, lack of time, an information overload, the non-involvement of staff in the planning of their training, facilitation limitations, lack of technical support and institutional challenges that involve infrastructure. The study further revealed that the principles of adult learning play a reciprocal role in the staff’s professional developmental challenges. In view of these findings, this study offers recommendations for improving the ICT training of staff members. / Educational Studies / M. Ed. (Adult Education)
