This 2-volume set includes extensive discussions of scattering techniques (light, neutron and X-ray) and related fluctuation and grating techniques that are at the forefront of this field. Most of the scattering techniques are Fourier space techniques. Recent advances have seen the development of powerful direct imaging methods such as atomic force microscopy and scanning probe microscopy. In addition, techniques that can be used to manipulate soft matter on the nanometer scale are also in rapid development. These include the scanning probe microscopy technique mentioned above as well as optical and magnetic tweezers.
This book aims at discussing the development of MOOCs in China in relation to MOOCs in other countries or areas. Based on the history of MOOCs, we summarize and compare the development of MOOCs in China and other countries with empirical evidence from a comprehensive investigation about MOOCs in Asian, United States, and Europe. Then we discuss about the importance of MOOCs in China and its role in the reform of higher education system, and the model of teaching and learning in China. After all, we provide suggestions about how to improve MOOCs at the national, institutional, and individual level. In this book, we analyse and present the current construction and development of MOOCs in China from four dimensions including platforms, courses, learners, colleges and universities based on huge empirical evidence from a comprehensive investigation of 14 platforms, 42 universities, 1388 MOOCs, and 22895 learners. Our investigation mainly focused on seven topics: platform construction and operation, learner groups, curriculum organization form, teaching interaction, learning evaluation model, learning support service, and courses certification and academic score system. Based on the investigation, we found there is an emerging trend of collaboration among government, universities and enterprise in the development of MOOCs in China, which provides great opportunities to build an innovative educational service system for all kinds of learners. We also discuss our findings in relation to the corresponding development of MOOCs in United States, Europe and other regions and then focus on the unique challenges that China faces, such as the lack of deep learning in MOOCs, the low information literacy and self-regulated learning abilities of MOOC learners, the lack of individualized support for MOOC learners, and so on. At last, this book summarizes the overall development of MOOCs in China and other countries and then put forward the future trends and suggestions in this field.
Flammability has been recognized as an increasingly important social and scientific problem. Fire statistics in the United States (Report of the National Commission on Fire Prevention and Control. "America Burning:' 1973) emphasized the vast devastation to life and property--12.000 lives lost annually due to fire. and these deaths are usually caused by inhaling smoke or toxic gases: 300.000 fire injuries: 11.4 billion dollars in fire cost at which 2.7 billion dollars is related to property loss: a billion dollars to burn injury treatment: and 3.3 billion dollars in productivity loss. It is obvious that much human and economic misery can be attributed to fire situations. In relation to this. polymer flammability has been recognized as an in creasingly important social and scientific problem. The development of flame-retardant polymeric materials is a current example where the initia tive for major scientific and technological developments is motivated by sociological pressure and legislation. This is part of the important trend toward a safer environment and sets a pattern for future example. Flame retardancy deals with our basic everyday life situations-housing. work areas. transportation. clothing and so forth-the "macroenvironment" capsule within which "homosapiens" live. As a result. flame-retardant polymers are now emerging as a specific class of materials leading to new and diversified scientific and technological ventures.
Adapted from the Charpentier "Te Deum in D Major" with an original school-friendly text, this is an accessible and positive way to ease your students into singing timeless choral music. An optional trumpet adds to the classic character. Majestic!
