Effects of axial conduction in laminar tube flow with convective boundaries     

B. Vick  M.N. Özişik  D.F. Ullrich 《Journal of The Franklin Institute》1983,316(2):159-173

Heat transfer in laminar tube flow with convective boundary conditions and axial heat conduction in the fluid is solved exactly. The effects of the external Biot numbers and the axial conduction in fluid on the temperature distribution and the local Nusselt number are determined for both the upstream and the downstream regions. In order to illustrate the effects of velocity profile, the results for the slug flow and the parabolic velocity profiles are plotted simultaneously. The heat transfer characteristics of the flow are found to be rather sensitive to the Péclét number, the external Biot numbers and the velocity profile in the thermal entrance region.  相似文献   

Autonomous and controlling reasons underlying achievement goals during task engagement: their relation to intrinsic motivation and cheating     

Ayşe Ozdemir Oz  Jennie F. Lane  Aikaterini Michou 《教育心理学》2016,36(7):1160-1172

The aim of this study was to investigate the relation of autonomous and controlling reasons underlying an endorsed achievement goal to intrinsic motivation and cheating. The endorsement of the achievement goal was ensured by involving 212 (M_age = 19.24, SD = .97) freshman students in a spatial task and asking them to report their most important achievement goal, as well as the reasons for adopting the goal, during the task. Results from a hierarchical regression analysis revealed that independent of the achievement goal the students adopted, the autonomous reasons for the endorsed goal were positively related to the indices of intrinsic motivation. Furthermore, the autonomous reasons underlying either performance or mastery-avoidance goals were negatively related to cheating. Alternatively, the controlling reasons for the endorsed goal were positively related to pressure and tension. The importance of considering both the ‘what’ and the ‘why’ aspect of achievement motivation are discussed.  相似文献   

The process of supervision in the turkish educational system: purpose, structure, operation     

Hasan Basri Memduhoğlu  Inayet Aydin  Kürşad Yilmaz  Sabri Güngör  Ebru Oğuz 《Asia Pacific Education Review》2007,8(1):56-70

The aim of this study is to provide information on the purposes, structure and operation of the process of supervision in the Turkish educational system. In this paper, the historical development of supervision services in the Turkish educational system, as well as the purposes and principles of educational supervision in Turkey and the structure of supervision in the Turkish educational system are defined. Moreover, the organization of sub-systems of the Ministry of National Education and that of supervision at elementary schools, hiring supervisors, their training, duties and responsibilities as well as working principles are presented. In addition, a detailed analysis of the supervision of institutions and teachers by supervisors is included.  相似文献

On some difference sequence spaces defined by a sequence of Orlicz functions     

ASMA BEKTAS Cigdem 《浙江大学学报(A卷英文版)》2006,7(12):2093-2096

INTRODUCTION Let w be the set of all sequences of real or com- plex numbers and R∞, c and c0 be the sequence spaces of bounded, convergent and null sequences x=(xk), respectively. A sequence x∈R∞ is said to be almost convergent (Lorentz, 1948) if all Banach limits of x coincide. Lorentz (1948) proved that 1 c? = ??? x =( xk ) :linm 1n ∑kn= xk s exists, uniformly in s???. Maddox (1967; 1978) has defined x to be strongly almost convergent to a number L if 1 linm 1n ∑k n= xk s? L=0,…  相似文献

Change Readiness among Teaching Staff at Anadolu University,Turkey     

Yavuz Akbulut  Abdullah Kuzu  Colin Latchem  Ferhan Odabaşi 《Distance Education》2007,28(3):335-350

Turkey’s Anadolu University is one of the world’s largest mega‐universities. It is engaged in strategic planning in response to changes in the expectations of the Turkish Higher Education Council and the community at large. In re‐examining its vision and strategic directions, Anadolu University needs to be informed on the knowledge, skills, and attitudes of its teaching staff, and the systems and support needed to assure their change readiness. This article examines the literature of organizational and educational change and its implications for the university. It reports on a study based on the relevant constructs from the literature and is designed to gauge the extent and nature of teaching staff knowledge, skills, practice, and research in educational and technological change, motivating and de‐motivating factors, change adopter types, and perceptions of the organizational climate for change. It considers the implications of these findings and draws conclusions about what would be needed to improve staff readiness for change.  相似文献   

Mobile marketing research: The-state-of-the-art     

Kaan Varnali  Ayşegül Toker 《International Journal of Information Management》2010

Rapid proliferation in the business potential of mobile marketing attracts researchers from various fields to contribute to the growing body of knowledge on the phenomena. Although the literature on mobile marketing is accumulating, the stream of research is still in the development stage, hence is highly inconsistent and fragmented. This paper aims to organize and classify the literature on mobile marketing and assess the-state-of-the-art in order to facilitate future research. The review covers 255 peer-reviewed journal articles from 82 journals published between 2000 and 2008. The resulting framework summarizes the progress in mobile marketing research and provides future research directions.  相似文献   

Usability design strategies for children： Developing children＇s learning and knowledge in decreasing their dental anxiety     

Wan Ahmad Jaafar Wan Yahaya  Sobihatun Nur Abdul Salam 《美中教育评论》2010,7(9):86-96

This paper presents an example of how usability design strategies for children can be designed into educational material using CD-ROM based multimedia application for assisting parents and teachers to develop children＇s learning and knowledge in decreasing as well as motivate children aged 7-9 years old to reduce their anxious feelings towards dental treatment. In this paper, the authors provide usability design strategies for children in designing the information interfaces and presentation of a PMLE （persuasive multimedia learning environment）. PMLE is designed based on the six design categories of guidelines for children which have been applied to this study： general interaction, text, multimedia, navigation and search, graphical user interface and content. The results authors were able to on presenting this PMLE to 240 primary school children selected at random show how the decrease children＇s dental anxiety and motivate the children to get ready for dental visit.  相似文献   

Unpacking the inequality among Turkish schools: Findings from PISA 2006     

Cengiz Alacacı  Ayhan Kürşat Erbaş 《International Journal of Educational Development》2010

The study investigates the effects of certain school characteristics on students’ mathematics performances in Turkey in the PISA 2006 while controlling for family background and demographic characteristics. Three models of Hierarchical Linear Modeling (HLM) are constructed. The results reveal that 55% of the variance is attributable to between-schools and the remaining 45% to individual student characteristics. About two-thirds of the 55% is explained by selectivity in admissions, time to study mathematics and students’ SES, gender and the geographical region. The findings are interpreted to explain why Turkish schools differed greatly in average student performance in PISA 2006 by using the conceptual efforts on school quality factors and family background characteristics.  相似文献
