This publication points the way to future initiatives to improve youth labour market and educational outcomes as identified by policy-makers and experts of OECD countries brought together at the Washington Conference "Preparing Youth for the 21st Century."

Teaching and learning in the 21st century have new implications for English language education since the core focus of learning in the 21st century involves collaboration, creativity, critical thinking and communication. Re-orientation of current curriculum, syllabus and content in English language education may be required and this could be attained by creating fundamental understanding of the concepts in relation to the main skills (reading, writing, listening and speaking), as well as other elements such as professional development of teachers, assessment and technology integration. This book aims to provide and facilitate such understanding to researchers, teachers, students and parents in deliberating, examining and resolving the main issues that beleaguer and challenge everyone and anyone involved in the teaching and learning in the 21st century. This volume draws together various researches, theoretical understandings, ideas and practices that reflect the above.

Covers the latest developments in PNT technologies, including integrated satellite navigation, sensor systems, and civil applications Featuring sixty-four chapters that are divided into six parts, this two-volume work provides comprehensive coverage of the state-of-the-art in satellite-based position, navigation, and timing (PNT) technologies and civilian applications. It also examines alternative navigation technologies based on other signals-of-opportunity and sensors and offers a comprehensive treatment on integrated PNT systems for consumer and commercial applications. Volume 1 of Position, Navigation, and Timing Technologies in the 21st Century: Integrated Satellite Navigation, Sensor Systems, and Civil Applications contains three parts and focuses on the satellite navigation systems, technologies, and engineering and scientific applications. It starts with a historical perspective of GPS development and other related PNT development. Current global and regional navigation satellite systems (GNSS and RNSS), their inter-operability, signal quality monitoring, satellite orbit and time synchronization, and ground- and satellite-based augmentation systems are examined. Recent progresses in satellite navigation receiver technologies and challenges for operations in multipath-rich urban environment, in handling spoofing and interference, and in ensuring PNT integrity are addressed. A section on satellite navigation for engineering and scientific applications finishes off the volume. Volume 2 of Position, Navigation, and Timing Technologies in the 21st Century: Integrated Satellite Navigation, Sensor Systems, and Civil Applications consists of three parts and addresses PNT using alternative signals and sensors and integrated PNT technologies for consumer and commercial applications. It looks at PNT using various radio signals-of-opportunity, atomic clock, optical, laser, magnetic field, celestial, MEMS and inertial sensors, as well as the concept of navigation from Low-Earth Orbiting (LEO) satellites. GNSS-INS integration, neuroscience of navigation, and animal navigation are also covered. The volume finishes off with a collection of work on contemporary PNT applications such as survey and mobile mapping, precision agriculture, wearable systems, automated driving, train control, commercial unmanned aircraft systems, aviation, and navigation in the unique Arctic environment. In addition, this text: Serves as a complete reference and handbook for professionals and students interested in the broad range of PNT subjects Includes chapters that focus on the latest developments in GNSS and other navigation sensors, techniques, and applications Illustrates interconnecting relationships between various types of technologies in order to assure more protected, tough, and accurate PNT Position, Navigation, and Timing Technologies in the 21st Century: Integrated Satellite Navigation, Sensor Systems, and Civil Applications will appeal to all industry professionals, researchers, and academics involved with the science, engineering, and applications of position, navigation, and timing technologies. pnt21book.com

A learner-centred curriculum provides space for the learner to be actively involved in knowledge production and learning. Such can only happen if the learner's confidence is boosted by a feeling of control and ability to manage his or her progress towards acquiring a qualification. The twenty-first century teacher must create an environment that not only supports the Four Pillars of Learning but also leads to learners being allowed a voice to ask pertinent questions. The teacher should be able to guide the student to full physical and mental maturity and should help to develop critical thinking, and the students should be encouraged to practice the truth and have self-respect and respect for other people. This can happen if the learner is afforded the opportunity to self-accept. If the learners fail to do so, they are likely to have lack of confidence, which will lead to lack of independence.

In this book, scientists who are pre-eminent in their fields focus on the crucial role of science in the transition away from a culture of war towards the construction of peace based on a capacity to anticipate and prevent destructive conflicts. The subject matter, wide-ranging and of great concern to people everywhere, includes the progress and prospects for a nuclear-weapon-free world; non-nuclear threats to peace and security; the building of legitimate world institutions; conflict resolution and the construction of peace; the local and global environmental dimensions of peace; the health hazards of nuclear chemical and biological weapons; and the interactions between health problems and poverty. Contents: Chiapas: Politics or War (R Benitez-Manaut); Nuclear Disarmament: Is This as Good as It Gets? (M M Bosch); The Future of Nuclear Weaponry and our Civilization (F Calogero); Nuclear-Weapon-Free Zones and Non-Proliferation (O M Sukovic); Technology and the Prevention of Genocide (D Andersen & A Moden); Asian Financial Crisis and China (Z-Q Xie); Ethnic Identity and Border Disputes in the Balkans (N Behar); Water Security in Southern Africa (N Dippenaar); Poverty, Disease and War (J Avery); Poverty, Public Health and Peace: A Southern African Perspective (R A Mogotlane); and other papers. Readership: Graduate students in social sciences.
