Abstract The research described in this article can be described as an explorative study that focused on obtaining and analysing perceptions and attitudes of public sector officials in Pretoria regarding the possible introduction of teleworking in their working environment. The term teleworking was understood in the sense of using computers to work from home or working at a distance away from the office. The research question that was posed was: What perceptions and attitudes exist among public sector officials in Pretoria that could contribute to, or impede, the acceptance of teleworking in South African government departments? Specific attention was given to perceptions of possible benefits or other impacts of teleworking, indications of public sector officials' ability to use computers for teleworking purposes, attitudes toward computers and teleworking, and the behavioural intention to use teleworking in future. The questionnaire and results were structured along the lines of the Technology Acceptance Model (TAM) of Davis. It was found that there was firm support among the officials for public sector teieworking - especially in terms of those views and perceptions that served as indicators for relevant TAM constructs such as 'perceived ease of use regarding teleworking', 'perceived usefulness of teleworking', 'attitude toward teleworking' and 'intention to use teleworking'.

The beauty of group-buying is that the price will go down as the value of accumulated orders is increasing. However, the beauty cannot be realized if many customers are waiting have a lower price. Therefore, it may affect the performance of the group-buying. How to design different incentives to induce customers to join the group-buying as early as possible is the purpose of this study. In the light of inducing buyers to join the group-buying as early as possible, three incentive mechanisms, time-based, quantity-based, and sequence-based, are proposed. In order to verify the performance of the three proposed new group-buying models compared with that of the traditional group-buying model, an experiment was implemented. According to the results of the experiment, we found that the time-based model can reduce customers¡¦ decision time before joining the group-buying. While the sequence-based model also can push customers to join the group-buying in the very beginning. As for the quantity-based model, it is in our expectation that the customers buy more than their original plan in order to get more discounts. We also observe that buyers' satisfaction is higher if the group-buying model can effectively reduce the price. Furthermore, the earlier customers join the group-buying, more satisfactions they will get. Besides, the buyers also agree with that the group-buying model can effectively reduce the price. Furthermore, we discover that the perceived value, perceived usefulness, and perceived easy of use can positively affect the buyers' attitude, and consequently, buyers are willing to join the group-buying in the future.

ABSTRACT The main purpose of this study is to investigate the usage of web-based teachers' training in elementary and high school. This study adopts motivational orientations and TAM to explore the related factors that affect the usage of web-based teachers' training. The study depends on literature analysis and uses the questionnaire to collect data. A total of 658 subjects attending teachers' training courses are from K12 Digital School. The collected data is processed and analyzed with SPSS for Windows 10.0, and statistical methods adopted in this study are descriptive statistics, t-test, one-way ANOVA, regression analysis and so on. The main findings show that there are 8 motivational orientations for web-based teachers' training and motivational orientations are significant differences among subjects in different age, status, school level and teaching years. Furthermore, computer self-efficacy, social relationships and attitude toward using will significantly affect the usage of web-based teachers' training positively, and perceived usefulness and perceived ease of use toward web-based training system will significantly affect attitude. As for perceived ease of use toward web-based training system, it will significantly affect perceived usefulness toward web-based training system and be affected by computer self-efficacy positively. Finally, based on the research findings, this study proposes conclusions and suggestions for the related organizations and the follow-up research.

Gruvindustrin är en bransch som är välkänd för att innehålla riskfyllt arbete. Ett sätt att öka säkerheten och hälsan hos de anställda är att använda sig av exempelvis positioneringsteknik och teknik som registrerar hälsan. Denna typ av teknik kan dock orsaka bland annatintegritetsproblematik vilket i sin tur kan påverka hur man ställer sig till den. Syftet med denna rapport var därför att undersöka vilka faktorer som påverkar acceptansen hos gruvarbetare för denna typ av teknik. Detta undersöktes genom att använda en modifierad version av TAM-modellen innehållande upplevd nytta, säkerhet, integritet och tillit. Utöver detta undersöktes även om det fanns någon åldersskillnad i acceptansen. Studien är utförd i ett samarbete mellan SIMS och LTU där en enkät skapades och besvarades av 275 gruvanställda vid LKAB. Resultatet visade att gruvarbetarnas acceptans för teknik generellt var positiv och att den modifierade TAM-modellen till stor del kunde förklara gruvarbetarnas acceptans. De faktorer som visat sig påverka acceptansen negativt var om gruvarbetarna upplevde att integriteten hotades, medan acceptansen påverkades positivt om de upplevde nytta av att se specifika personer i en kartvy. Utöver detta påvisade resultatet även att om gruvarbetarna såg en nytta med tekniken ur ett säkerhetsperspektiv påverkades acceptansen positivt. Den faktor som inte visades ha prediktivt värde från den modifierade TAM-modellen var tillit. En åldersskillnad kunde också fastställas i vissa aspekter av acceptansen.

This research study examined the acceptance of the intranet in restaurant franchise systems. The widely accepted Technology Acceptance Model (TAM) developed by Davis (1986, 1989) was the basis for this study. TAM is an excellent model to predict information technology (IT) usage and is based on the Theory of Reasoned Action (TRA). Therefore, TAM was adopted in this study of intranet acceptance. Furthermore, this study attempted to see if the earlier results of TAM are still valid. The original model was modified to include one external variable, franchise support. Data were collected from franchise restaurant systems throughout the United States, excluding Alaska and Hawaii. Of 3,500 questionnaires distributed to individual users of intranet, 161 contained usable responses. The results of regression analysis confirm that TAM is valid for additional applications such as evaluating the intranet in restaurant franchise systems. / Ph. D.

A survey conducted by the United Nations in 2016 endorses this fact, showing a high rate of technological development with respect to e-government. However, the same publication showed the low rate of citizen participation about it. These results show how, although there are many government technological services, these do not focus on the citizen or in their active participation, but mainly on technological development. In the present study, an adoption model is proposed, extending the Technology Acceptance Model (TAM) incorporating public value, specifically environmental sustainability, as an external variable. The validation of the proposal was made through a validated survey with experts in the environmental field and applied to citizens of the Peruvian capital. Our results show that environmental sustainability is a factor that positively affects the adoption of e-government in Peru and that should be considered by the authorities as an enhancer of citizen participation about it.

Purpose: Low citizen adoption rates jeopardize the success and proliferation of e-government systems. This study aims to understand how the perception of environmental sustainability (ES) can influence a citizen’s intention to use e-government systems. Design/methodology/approach: In a case study in Peru, the technology acceptance model (TAM) adoption model is extended with the construct of ES and evaluated with structural equation modeling. An 18-element, in-person survey was constructed and administered to citizens of Lima, Peru who had prior exposure to e-government systems. Findings: The results show that citizens can be positively influenced to adopt e-government systems if they perceive that doing so will contribute to ES. Research limitations/implications: As this was a preliminary study, further research should focus on specific, as opposed to general, e-government systems, as well as encompassing a broader cross section of the population. Practical implications: Administrators of e-government initiatives can consider public-interest factors, alongside of the common self-interest factors, when looking to improve adoption rates of e-government systems. Originality/value: This is the first time that TAM has been extended with the construct of ES.

Welche E-Learning- und Social Web-Anwendungen nutzen Studierende innerhalb ihres Studiums und aus welchen Gründen tun sie dies? Die folgende Masterarbeit widmet sich dieser Fragestellung. Unter der Einbeziehung des Technology-Acceptance-Models (TAM) und dem Uses-and-Gratification Ansatzes werden Nutzungsmotive aus dem Forschungsstand herausgearbeitet und empirisch getestet (Studierende der TU Dresden, n=1242). Studierende nutzen demnach Anwendungen für das Studium, die sie auch schon im alltäglichen Leben verwenden. Besonders im Bereich der Zusammenarbeit sowie zur Kontaktaufnahme zu Kommilitonen werden Anwendungen aus der Freizeit genutzt. Unverzichtbar für das Studium ist für die meisten Studierenden die Nutzung des Lernmanagementsystems, welche zumeist von Dozenten vorgeschrieben ist. Nur so ist es den Studierenden möglich, auf bestimmte Lerninhalte, die für das Bestehen des Studiums notwendig sind, zuzugreifen. Die Arbeit leistet einen Beitrag zur Beforschung des Mediennutzungsverhalten von Studierenden. Die Ergebnisse können wiederum für die Strategieentwicklung im Bereich des Einsatzes von Lehr- und Lerntechnologien in der Hochschule nützlich sein.

Skiftet från en bensindriven bil till en elbil är ett ämne som drastiskt accelererat under de senaste fem åren med motivation av miljömässiga fördelar. Detta skifte börjar inte bromsa in, utan snarare att fler konsumenter väljer en elbil framför en bil med en förbränningsmotor. I takt med att bilen blir mer avancerad, blir även tekniken inuti bilen mer komplicerad för konsumenter att använda. Syftet med denna studie är att jämföra köpintentioner av en Elbil mellan Tyskland och Storbritannien, med specifik hänsyn till Technology acceptance model (TAM). Studien är genomförd som en kvantitativ undersökning med Polestar som samarbetspartner. För Tyskland respektive Storbritannien är respondenterna 54 respektive 56 styck. Analysering av resultat har gjorts genom en deskriptiv analys samt en korrelationsanalys, för att hitta mönster i de datamaterial som insamlats. Resultatet påvisar att det finns såväl likheter som skillnader i köpintentionerna för såväl Tyskland som Storbritannien. Exempelvis påvisar resultatet att TAM har en likvärdig inverkan på köpintentionerna hos de båda länderna, samtidigt som exempelvis miljö har en större inverkan hos konsumenter i Storbritannien än i Tyskland. / The shift from a petrol-powered car to an electric car is a topic that has accelerated dramatically over the past five years with the intention of environmental benefits. This shift is not starting to slow down, rather more consumers are choosing electric vehicles over cars with internal combustion engines. As the car becomes more advanced, the technology in the car also becomes more complicated for consumers to use. The purpose of this study is to compare the purchase intentions of electric cars in Germany and the United Kingdom, with specific regard to the Technology acceptance model (TAM). The study was conducted as a quantitative study partnered with Polestar. For Germany and the United Kingdom, the respondents are 54 and 56 respectively. Analysis of results has been done through descriptive analysis and correlation analysis, to find patterns in the data material collected. The results show that there are similarities and differences in the purchase intentions for both Germany and the United Kingdom. For example, the results show that TAM has an equal impact on the purchasing intentions of the two countries, while for example, the environment has a greater impact on consumers in the UK than in Germany.
