School Leadership - International Perspectives


Book Description

Recent research into school effectiveness has corroborated the theory that the school leader plays a pivotal role making their school a successful institution, and is most often cited as the key factor in a school’s development. Reflecting the importance it is given in the today’s education landscape, this book explores the latest trends in school leadership from both theoretical and practical perspectives. Each chapter provides insight into an aspect of current research, with detailed case studies coming from as far afield as Hong Kong and Canada. In the context of the ever-increasing burden of responsibility placed on education management to safeguard and enhance the quality of education they provide, school leadership is now a core concern of policy makers. In addition, most countries are undertaking fundamental education reforms that will have a major influence on the nature of school leadership. Offering the most up-to-date research on this central issue, this book will both inform and shape the debate.




The Singing Life of Birds


Book Description

Listen to birds sing as you’ve never listened before, as the world-renowned birdsong expert Donald Kroodsma takes you on personal journeys of discovery and intrigue. Read stories of wrens and robins, thrushes and thrashers, warblers and whip-poor-wills, bluebirds and cardinals, and many more bird. Learn how each acquires its songs, how songs vary from bird to bird and place to place, how some birds' singing is especially beautiful or ceaseless or complex, how some do not sing at all, how the often quiet female has the last word, and why. Hear a baby wren and the author’s own daughter babble as each learns its local dialect. Listen to the mockingbird by night and by day and count how many different songs he can sing. Marvel at the exquisite harmony in the duet of a wood thrush as he uses his two voice boxes to accompany himself. Feel the extraordinary energy in the songs just before sunrise as dawn’s first light sweeps across this singing planet. Hear firsthand the unmistakable evidence that there are not one but two species of marsh wrens and two species of winter wrens in North America. Learn not only to hear but to see birds sing in the form of sonagrams, as these visual images dance across the pages while you listen to the accompanying audio. Using your trained ears and eyes, you can begin your own journeys of discovery. Listen anew to birds in your backyard and beyond, exploring the singing minds of birds as they tell all that they know. Join Kroodsma not only in identifying but in identifying with singing birds, connecting with nature’s musicians in a whole new way. Please note: this ebook includes embedded audio files. You will only be able to access these files from a device that supports embedded audio.

Exploratory Search


Book Description

As information becomes more ubiquitous and the demands that searchers have on search systems grow, there is a need to support search behaviors beyond simple lookup. Information seeking is the process or activity of attempting to obtain information in both human and technological contexts. Exploratory search describes an information-seeking problem context that is open-ended, persistent, and multifaceted, and information-seeking processes that are opportunistic, iterative, and multitactical. Exploratory searchers aim to solve complex problems and develop enhanced mental capacities. Exploratory search systems support this through symbiotic human-machine relationships that provide guidance in exploring unfamiliar information landscapes. Exploratory search has gained prominence in recent years. There is an increased interest from the information retrieval, information science, and human-computer interaction communities in moving beyond the traditional turn-taking interaction model supported by major Web search engines, and toward support for human intelligence amplification and information use. In this lecture, we introduce exploratory search, relate it to relevant extant research, outline the features of exploratory search systems, discuss the evaluation of these systems, and suggest some future directions for supporting exploratory search. Exploratory search is a new frontier in the search domain and is becoming increasingly important in shaping our future world. Table of Contents: Introduction / Defining Exploratory Search / Related Work / Features of Exploratory Search Systems / Evaluation of Exploratory Search Systems / Future Directions and concluding Remarks

Eurasian Steppes. Ecological Problems and Livelihoods in a Changing World


Book Description

Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.
