Abstract

Drawing on the Technology Acceptance Model (TAM), this exploratory study examines the preservice teachers’ adoption of mobile technologies through the factors of current use, instructional use and future use in their teaching practices. Participants were 466 pre-service computer teachers enrolled at a public university in Turkey. A questionnaire developed by the researchers was used to collect data. Results indicated that the current use and instructional use factors had a strong positive correlation and also there was a similar correlation with the factor of future use and current use. Relationships between current, instructional, and future use of mobile technologies explained within the context of perceived usefulness, ease of use, and behavioural intention constructs of the TAM.

Abstract

Issues of communication, isolation, and education are part of our everyday lives, whether private or professional. The behaviour of the young generation at school and at home has different forms. It demonstrates their actions, way of thinking and feeling. Furthermore, their behaviour expresses their future tendencies. These forms of behaviour are strongly influenced by a lack of communication. As a result, the educational process is made harder, sometimes even impossible. Many experts in ethics, pedagogy and psychology have been paying attention to this issue and have started to evaluate its impact on the young.

Abstract

In this paper, preceding changes and current situation in agricultural landscape pattern were elaborated as well as future transition was discussed. The North-Western Region of Poland was chosen as a study area, however, the research was conducted at the regional level, in provinces of this region including: Lubuskie, Wielkopolskie and Zachodniomomorskie. For analysis statistical data from Common Agricultural Census, containing the last two decades, between 1990-2010, were extracted. Based on established knowledge and proposed approach driving forces of landscape changes were identified. The research deals with the following aspects: 1) identification of underlying trends of landscape changes that took place over the study period, 2) finding driving forces responsible for cause-effect relationships in landscape alteration, 3) recognition of farmers’ reasons for what they took actions leading to landscape changes, and 4) identification of major current and foreseeable future tendencies of modification of landscape pattern. Political, economic and social driving forces, as the most affecting, were recognized and their influence on agricultural landscape structure was analyzed

Abstract

Natural gas is still the primary input of the Hungarian heating and cooling systems, therefore it still makes most of the overheads. One of the main obstacles of a competitive district heating system is the public opinion which still considers this service more expensive than the traditional heating forms. According to the absolute numbers this assumption might be valid but from a more accurate economic perspective, heat production has more aspects to stress. Most people forget about the simple fact that the maintenance costs of natural gas based systems are rather outsourced to the consumer than in the case of district heating. Furthermore, the uneven rate of the fixed and variable costs of this technology does not prove to be optimal for service developments. Investigating the future tendencies highlight that encouraging the efficiency improvement of district heating and the spread of technological innovation in the sector does not belong to the top priorities. Still, avoiding this problem it could lead serious deadweight losses in the case of the heating sector.
