This cross-sectional study analysed the association of sedentary behaviour (SB) and standing with waist circumference. Finnish adults aged 30-75 years from a sub-sample of population-based Health 2011 Study used a hip-worn tri-axial accelerometer (Hookie AM20, Traxmeet, Ltd, Espoo, Finland) for seven days. Those 1405 participants (57% women) who used accelerometer at least four days, minimum of 10 hours/day, were included. SB and standing were analysed in 6s epochs using validated algorithm. Daily total time, daily number and accumulated time from bouts (30s–5min,30s–10min,30s–15min,30s 30min,>5min,>10min,>15min, >30min) as well as daily number of sit-to-stand transitions were determined. Waist circumference (cm) was measured in standardized way. Participants’ mean age was 52 years (SD 12.2). Mean waist circumference was 97cm (SD 12.3) in men and 87cm (SD 12.7) in women. According to multivariable stepwise linear regression analysis, sit-to-stand transitions [standardised regression coefficient (β)= -0.14, 95%CI -0.20 to -0.09], standing bouts of 30s–5min (β= -0.21, 95%CI -0.26 to -0.15) and number of 30s-30min SB bouts (β=0.12, 95%CI 0.06 to 0.17) were most strongly associated with waist circumference. Besides assessing total SB time, future studies should assess also different bout lengths of SB and sit-to-stand transitions and standing times should be assessed separately. 相似文献

The purpose of this article is to provide an overview of how the employees of higher education institutions perceive the impact of external evaluations. The study was conducted using the concurrent mixed method and involved 361 employees from Estonian universities and professional higher education institutions. The results indicated that evaluation is mostly deemed necessary at the levels of the organisation and the system; from the personal viewpoint of an employee, positive effects of external evaluations are perceived to a lesser degree. The negative influences mentioned were increased bureaucracy, extra work and stress. Top managers of institutions most often saw the positive influences from external evaluations since they help to implement reorganisations and development activities within an organisation. Managers perceived the positive effects of external evaluations on their everyday work as well, more than other employees did. Researchers felt the positive effects of external evaluations least. Nearly a quarter of all employees of higher education institutions do not perceive the effects of external evaluations on their everyday work at all. Employees of professional higher education institutions perceive the positive effects of external evaluations to a greater extent than employees of universities do, indicating that external evaluation has contributed to the development of their organisations. The differences in opinions of the employees of higher education institutions regarding perceived positive and negative impacts of external evaluations—whether on individual, organisation or system points of view—indicate that employees do not identify closely enough with the organisation and its strategic goals. 相似文献

This paper discusses a goal-oriented project called Distance Learning in Multimedia Networks (ETÄKAMU) that was a part of the Finnish Multimedia Programme (FMP). The project started in February 1996 and lasted until January 1999. The project combined the efforts of Finnish telecommunication companies, content providers, publishing houses, hardware companies and educational institutions in the field of distance learning.
This paper describes the background, the goals and part of the results of the ETÄKAMU project as well as the project's organisation. The main goals of the ETÄKAMU project were to research, develop and evaluate open learning environments using computer networks and computers in learning.
The pedagogical background of the project is based on seven qualities of meaningful learning that are applicable to lifelong learning independent of time and place. The ETÄKAMU project arranged teaching experiments and user trials for various learners in different content areas and in different learning environments. Feedback and data were gathered via an investigation of how various pedagogical and technical solutions function in practice. This paper presents some pilot areas of the ETÄKAMU project and main results received in the project. 相似文献

Open education, including the use of open educational resources (OER) and the adoption of open education practice, has the potential to challenge educators to change their practice in fundamental ways. This paper forms part of a larger study focusing on higher education educators’ learning from and through their engagement with OER. The first part of the study was a quantitative survey investigating educators’ learning behaviour when they learned to use OER in their practice. The second part of the study explored qualitatively how educators engaged with OER and how they conceptualised their learning. Data were gathered through interviews with 30 higher education educators. This paper reports the analysis of these interviews. The analysis draws on the theory of self-regulated learning and cultural–historical activity theory to explore the challenges adult education practitioners encounter when changing their practice. The study tests the application of a framework that traces the discursive manifestations of contradictions, exploring how this framework can be used to examine different aspects of self-regulated learning as educators learn how to use OER. We have identified three distinct tensions in higher education educators’ practice: tensions between the emerging needs of the individual (as he or she adopts new forms of practice) and organisational policies; between the transfer of responsibilities from educators to students as new practice is embedded and institutional accountability; and between cost efficiency and learning objectives. The framework for the discursive manifestations of contradictions was a useful tool used to surface these apparent tensions. 相似文献

The purpose of this study was to ascertain the attitudes of academic staff towards their own work as well as towards external evaluations. The study was based on (1) an analysis of assessment reports of institutional accreditations conducted by the Estonian Quality Agency for Higher and Vocational Education and (2) self-determination theory on intrinsic and extrinsic motivation. The satisfaction of academic staff with their own teaching and research competencies was measured and links among the following attitudes were analysed: sense of competence, intrinsic motivation for research, attitudes towards assessment of students and towards external evaluations. The results indicate that a correlation between attitudes towards work and towards external evaluation exists and that the attitudes of academic staff at universities and professional higher education institutions differ. The study involved 252 academic staff members and showed that competent and intrinsically motivated people perceive external evaluation more positively, thus supporting self-determination theory. 相似文献

以柠檬酸作为螯合剂,通过溶胶-凝胶法合成尖晶石型锂离子电池正极材料LiMn1.8-xCo0.2CrxO4并用XRI和SEM表征其微结构,利用电化学测试考察材料的电化学性能.测试结果表明,所合成的材料具有完整的尖晶石结构,Cr3+的掺入并不会导致材料相结构的变化,说明Cr3+(d3)以替代形式进入尖晶石结构并替代八面体骨架中的Mn3+(d3).Cr3+对Mn位的掺杂使材料主体结构得到了稳定且具有很好的充放电平台. 相似文献
