Available in PDF, EPUB and Kindle. Book excerpt: From large cities to rural communities, gay men have long been impassioned pioneers as keepers of culture: rescuing and restoring decrepit buildings, revitalizing blighted neighborhoods, saving artifacts and documents of historical significance. A Passion to Preserve explores this authentic and complex dimension of gay men’s lives by profiling early and contemporary preservationists from throughout the United States, highlighting contributions to the larger culture that gays are exceptionally inclined to make.
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
Download or read book Sustainable Horticultural Systems written by Dilip Nandwani and published by Springer. This book was released on 2014-10-14 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable horticulture is gaining increasing attention in the field of agriculture as demand for the food production rises to the world community. Sustainable horticultural systems are based on ecological principles to farm, optimizes pest and disease management approaches through environmentally friendly and renewable strategies in production agriculture. It is a discipline that addresses current issues such as food security, water pollution, soil health, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, entomology, ecology, chemistry and food sciences. Sustainable horticulture interprets methods and processes in the farming system to the global level. For that, horticulturists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable horticulture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable horticulture treats problem sources.

Book excerpt: As men and women throughout England were called up for war work during World War II, the country needed to generate as much food and wealth as possible to support them. Children quickly came to be seen as a vital resource. Many children worked the land, planting and harvesting crops, raising money for the war effort, and carrying out a range of other tasks. That war work followed on debates throughout the preceding decades about the character and proper activities of childhood, debates that saw commentators in education and workers' organizations arguing about whether children should stay in school and learn or should combine their education with war-related work. The work of children during the war raised a question that still has relevance today: Should children be conceptualized as citizens of the future or as participating citizens now? That debate has led to even larger questions about the social construction of childhood. As children have increasingly withdrawn from paid and unpaid work, their contribution today can best be understood through their work at school, though that work is often disguised or devalued as mere socialization. The interwar years and the war years in England were a key time for re-thinking childhood, and the issues that were raised then still have relevance to the role of children in society today.

Download or read book Insects and the Life of Man written by V.B. Wigglesworth and published by Springer. This book was released on 1976-11-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Patrick A. Buxton was appointed by the London School of Hygiene and Tropical Medicine in 1926 to head their Department of Medical Entomology, he had formed the opinion that the control of the insect-borne diseases of the tropics was being impeded by lack of knowledge about the physiology of insects. He persuaded the Board of Management to agree to the selection of a lecturer who would endeavour to advance the subject of insect physiology; and at the suggestion of Sir Gowland Hopkins, under whom I had worked at Cambridge, and with the support of Sir Walter Morley Fletcher, Secretary of the Medical Research Council and a member of the Board of Management, I was appointed to this post - with opportunity for extensive travel to study medical entomology in the tropics and with abundant time for research. Some seventeen years later, during the war years, W. W. C. Topley, as Secretary of the Agricultural Research Council, was faced with the urgent need for improved methods of control of insect pests in agriculture and horticulture by insecticidal or other means. As a support for this objective he recommended the establishment of a Unit of Insect Physiology to carry out basic research which would be of potential value to agriculture; and I was invited to act as director. So once again I was able to undertake world-wide travel - to learn the elements of agricultural entomology.
