Teachers in a large, all-male urban school in Jordan were interviewed about their perceptions of the most frequently occurring student misbehaviour. It was hoped to be able to identify the causes of such 'disruption' to teaching and learning in the school. Teachers spontaneously identified eight forms of student misbehaviour, which reflected clearly different kinds of interference with the teacher's authority. Teachers showed great awareness of the constraints which operate in the school context, which in turn affect their means of managing discipline in the classroom. Though this study was undertaken in a context which is significantly different from England, it is interesting that the issues these teachers saw themselves confronted with were not significantly different from those reported in this country. The conclusions that the researchers draw from their data have relevance beyond the specific context in which this study was undertaken.  相似文献

With the advancement of disruptive new technologies, there has been a considerable focus on personalisation as an important component in nurturing users' engagement. In the context of smart cities, Internet of Things (IoT) offer a unique opportunity to help empower citizens and improve societies' engagement with their governments at both micro and macro levels. This study aims to examine the role of perceived value of IoT in improving citizens' engagement with public services. A survey of 313 citizens in the UK, engaging in various public services, enabled through IoT, found that the perceived value of IoT is strongly influenced by empowerment, perceived usefulness and privacy related issues resulting in significantly affecting their continuous use intentions. The study offers valuable insights into the importance of perceived value of IoT-enabled services, while at the same time, providing an intersectional perspective of UK citizens towards the use of disruptive new technologies in the public sector.  相似文献

This study examines gender differences of teachers on their mathematical knowledge for teaching in the context of single-sex classrooms in Saudi Arabia. A translated version of the Mathematical Knowledge for Teaching (MKT) instrument (Learning Mathematics for Teaching [LMT], 2008) in Number and Operation Content Knowledge (CK) and Knowledge of Content and Student (KCS) scales were administered to 197 teachers (146 male and 51 female). Two-sample t test and multiple regression were conducted to compare the two groups and test the effect of teacher background variables. Female teachers significantly scored better than their male counterpart. Gender, years of teaching experience, and specialization significantly predicted teachers’ content knowledge, F(3, 187) = 13.180, explaining 41.8 % of the variance. Only gender and specialization significantly predicted teachers’ knowledge of content and student, F(2, 191) = 6.335, explaining 24.9 % of the variance. Further comparing items in the MKT instrument where female teachers outperformed male teachers confirmed that female teachers were better in attending to the content knowledge in the context of student’s learning.

Massive oil revenues are currently fueling a surge in the number of educational institutions in the Gulf Cooperation Council (GCC) countries, presenting leadership at all levels with many unprecedented questions. In particular, the growth and reform of higher education challenges the delicate balance between academic freedom and Arab cultural values. This paper describes faculty perceptions of academic freedom at a major GCC national university. Faculty members’ views and perceptions regarding academic freedom are presented based on interviews, questionnaire responses, and the authors’ own thoughts. Findings indicate that faculty members have complex and often contradictory understandings of academic freedom and related responsibilities and often engage in self-censorship. The authors discuss these findings by engaging in self-reflection regarding their own perspectives and personal experiences.  相似文献

High performance multiphase motor drive requires precise knowledge of the state quantities and the machine parameters. Access to these state quantities is through measurement using sensors whose accuracy is paramount to achieve the performance level required by industrial applications. However, the problems of the parameters variations, inaccessibility to the measurement of some states, no-observability of the machine in some regions, the cost of the sensors and their lack of precision, make this very difficult task. To address these problems, it is necessary to resort to soft sensors through the design of observers and estimators. In multiphase induction motor drive, the observation problem arises especially for rotor flux that is not accessible for measurement. About the parameters variations, the rotor resistance and the stator resistance are the most critical parameters of the machine because their influence is crucial for the control and observation. The change in the resistances can be as large as 40–50% of the rated value, which may affect the control adversely. This paper develops a new structure of an adaptive sliding mode observer based on an online estimation of the rotor resistance value in order to avoid the effect of its variation in the rotor flux oriented control. The results show convergent (the errors in the transient and steady states are 5% and 1%, respectively) behavior of the drive using the proposed control scheme for large rotor resistance variation under loaded condition. The stability of the drive is proved using Lyapunov criteria. The simulation results are validated using real time implementation.  相似文献

The adoption and diffusion of electronic government is often impeded by many social and individual factors relating to citizens. In this respect, intermediaries have emerged as a new model for delivering e-government services to overcome such obstacles. This study aims to examine the role of intermediaries in facilitating e-government adoption and diffusion using a survey based empirical study of 502 participants in Madinah City in Saudi Arabia. An extended UTAUT model is used as the theoretical basis utilizing trust in the Internet and Intermediaries. The results of this study show that there are significant relationships among the factors that influence intention to use e-government, namely, performance expectancy, effort expectancy, and trust of intermediary. In addition, the findings show that there is a significant relationship between facilitating conditions and usage behavior proving that intermediaries can influence adoption of e-government services.  相似文献

This study investigated the relation between motivational goals and university intentions, school valuing and school achievement. The premise of this study is that motivational goals play a key role in academic values and achievement. Confirmatory factor analysis was conducted to establish the construct validity of the motivational measures drawn from the Inventory of School Motivation (ISM): mastery (effort and task), performance (competition and social power), social solidarity (social concern and affiliation), extrinsic (praise and token). A set of eight regression analyses was conducted to examine the relations among these eight motivational measures, future goals to attend college, the value of school and six school subjects. Eight regression equations revealed that effort and task were the most significant predictors of the dependent variables of university intention, valuing school and school achievement scores. Students in Qatar exhibited ‘effort and task’ in goal motivation in relation to students’ beliefs regarding future academic goals and achievement scores in school subjects. As Qatar is a highly gender-segregated society, analyses were also conducted by gender.  相似文献

INTRODUCTION Water management is one of the critical opera-tion issues in proton exchange membrane (PEM) fuelcells. Spatially varying concentrations of water inboth vapour and liquid form are expected throughoutthe cell because of varying rates of production andtransport (Sui and Djilali, 2005). Devising betterwater management is therefore a key issue in PEMFCdesign, and this requires improved understanding ofthe parameters affecting water transport in the mem-brane.

References to relations between states, regions, communities and cultures have been a staple of historical thinking on the Mediterranean from the nineteenth century to the present day. Weathering changing academic trends and fashions, this vision of the Mediterranean has shaped the development of relevant historiographies, defining assumptions and approaches to an unrecognised extent. Focusing on the trajectory of this “Mediterranean of relations” in the historiography of the medieval Maghrib, this paper outlines some of the effects of its prevalence on the evolution of the concept of Mediterranean and argues for the inclusion of these considerations in the ongoing discussions around the medieval Mediterranean.  相似文献
