School culture is playing an increasingly important role in school performance and educational development. Within the national campaign in China for the innovative and sustainable development of education, local governments in Beijing Municipality have encouraged and facilitated educational innovation toward better school culture. In recent years various initiatives have been undertaken by a select group of schools to develop strategies and further action toward innovation and change. This book documents an investigation of how teachers and principals perceive school culture development in China. A survey was conducted among 1,992 informants from 37 schools (located in four different districts) in Beijing Municipality. The results of this study indicated that the respondents had overall positive perceptions of school culture construction and development in the educational change process. In general, they showed a positive attitude toward the school culture improvement initiatives, reported satisfaction about their current school culture and held confidence in the direction their school culture is heading. The study demonstrated that certain factors, such as school geographical location and respondents' job duty, job title, and gender, make a difference in how participants perceive their school's culture. Teachers and principals from a less economically developed district had less awareness of, involvement in, and understanding of school culture development in all its aspects. A notable gap between teachers and principals was identified in their perception of the core values and norms of the school and of communication between teachers and principals. This study suggests that for educational development to be further carried forward successfully, there is an urgent need for better distribution of educational resources (both financial and leadership), common understanding, agreed-upon goals, and efficient communication between principals and teachers.

Key Factors in Postgraduate Research Supervision - A Guide for Supervisors is designed to inform and support university academics and researchers who are taking on the responsibilities of postgraduate research student supervision. It is aimed at early career professionals, who may be undertaking supervision for the first time, and also experienced supervisors seeking to develop a more formal framework for their supervision, in an increasingly complex academic environment. The objective of the book is to help supervisors create the complete postgraduate student. That is, an individual who can develop the rigors and disciplines of research conduct and research writing, as well as a broader understanding of the environment in which many postgraduate qualified professionals will work. The majority of postgraduate research students in the modern world ultimately use their acquired skills to work outside the university research environment, so emphasis is given to preparing research students for these varied roles, which can include management; commercial research or start-up company pathways. Any competent academic can be a good research supervisor when things are going well. Real supervisory skills only come into play when things have gone awry. That is when a professional and structured approach to problem solving and conflict resolution is required. This book seeks to provide the framework in which supervisors can develop such an approach. The topics covered in this text cover the spectrum of the supervisory process, from understanding the university research environment, through to recruiting students; induction; planning of the research program; peer review and thesis/dissertation preparation. Additionally, important peripheral issues, such as preparing graduates for various future roles; managing collaborative research programs; managing cases of misfeasance, and developing long-term relationships with students are also covered.

Short computing times are crucial for timely diagnostics in biomedical applications, but lead to a high demand in computing for new and improved imaging techniques. In this book reconfigurable computing with FPGAs is discussed as an alternative to multi-core processing and graphics card accelerators.

Over the recent years, few books have been published covering all the subjects needed to understand the very fundamental concepts of cell planning. Most books which deal with this topic are destined to very specific audiences, and the vast majority introduce the subject at a very basic, or technical, level, or are destined to an academic audience. Cellular Network Planning begins with an introduction to the subject, covering conventional and contemporary wireless systems. Spectral allocation and the frequency plan are discussed, along with the essential characteristics of wireless systems. The design of mobile cellular systems includes cell planning, traffic and channel problems. The book presents a review of existing models, considering both green field dimensioning and network expansion strategies, and discusses multi-objective optimization and base station deployment based on artificial immune systems. It also discusses a cost-effective base station deployment approach based on artificial immune systems, and introduces the modified MO-AIS algorithm.

New Topics in Simulation and Modeling of RF Circuits addresses two main topics: simulation of RF circuits and new models of nonlinear power BAW resonators and filters.Since RF circuits have several unique features, and all analysis methods are based on the circuit essential properties, the book begins by describing the properties of RF circuits, characterization of circuits with customary and uncustomary behavior and some theorems of solutions existence and uniqueness for dynamic nonlinear circuits. Thereafter, the main time domain and frequency domain analysis methods for RF circuits are presented. The advantages and disadvantages of each method have been highlighted, and an algorithm for the time step choice in transient analysis based on energy balance errors is also presented. Lastly, the final part contains some nonlinear circuit models of power BAW resonators. The behavioral models for the time domain analysis are simple circuits containing weakly nonlinear elements. The behavioral models for frequency domain analysis are based on the measured values of the frequency dependent S parameters for a set of incident powers. S parameters corresponding to certain intermodulation products of practical interest are also considered. The physical models contain artificial transmission lines with nonlinear circuit elements corresponding to mechanical and electrical nonlinearities.

Information on the changing epidemiology and expanding nosological range of Q fever in humans has gained much attention in the past decade. Q fever is a zoonotic disease caused by the highly infectious pathogen Coxiella burnetii and has global distribution with important health, social and economic implications. A number of other properties and characteristics of the causative agent and disease, define Q fever as a lasting and difficult veterinary and epidemiological problem, namely: the adaptability of C. burnetii and its high resistance in the external environment; the possibility of the existence of the agent in three- and two-member parasitic systems; the availability of natural and agricultural foci of infection; peculiarities of pathogenesis in humans and animals, and the mechanisms of excretion of the pathogen into the environment; and the high susceptibility of non-immune populations of animals and people. Given that C. burnetii is included in the arsenal of bacteriological weapons as agent with potential bioterrorist threat must be borne in mind the strategic importance of this microorganismThis book summarizes and analyzes the scientific facts and developments about Q Fever researched worldwide and performed by the author to propose a system for monitoring, control and prevention covering the main necessary actions, measures and activities in the fight against this fever. There is an uneven level of knowledge of Q fever in animals and humans in various countries on the planet, while the assessment of the relevance of the problem is often ambiguous and unrealistic in terms of veterinary, medical and social and economic aspects, which can result in an incomplete diagnosis, inaccurate information about the spread of disease and lack of purposeful struggle. The scientific topics discussed include: Biological, morphological and immunological properties of Coxiella burnetiiDiagnosis, clinical forms and manifestations, pathologic changesEpidemiology of Q fever in animals and humansPrevention and Control
