Everything you need to create exciting thematic science units can be found in these handy guides. Developed for educators who want to take an integrated approach, these teaching kits contain resource lists, reading selections, and activities that can be easily pulled together for units on virtually any science topic. Arranged by subject, each book lists key scientific concepts for primary, intermediate, and upper level learners and links them to specific chapters where resources for teaching those concepts appear. Chapters identify and describe comprehensive teaching resources (nonfiction) and related fiction reading selections, then detail hands-on science and extension activities that help students learn the scientific method and build learning across the curriculum. A final section helps you locate helpful experiment books and appropriate journals, Web sites, agencies, and related organizations.

A low-dimensional magnet is a key to the next generation of electronic devices. In some respects, low-dimensional magnets refer to nanomagnets (nanostructured magnets) or single-molecule magnets (molecular nanomagnets). They also include the group of magnetic nanoparticles, which have been widely used in biomedicine, technology, industries, and environmental remediation. Low-dimensional magnetic materials can be used effectively in the future in powerful computers (hard drives, magnetic random-access memory, ultra-low power consumption switches, etc.). The properties of these materials largely depend on the doping level, phase, defects, and morphology. This book covers various nanomagnets and magnetic materials. The basic concepts, various synthetic approaches, characterizations, and mathematical understanding of nanomaterials are provided. Some fundamental applications of 1D, 2D, and 3D materials are covered. This book provides the fundamentals of low-dimensional magnets along with synthesis, theories, structure-property relations, and applications of ferromagnetic nanomaterials. This book broadens our fundamental understanding of ferromagnetism and mechanisms for realization and advancement in devices with improved energy efficiency and high storage capacity.

"The best way of handling the question of how much to give the poor, politicians have discovered, is to avoid doing anything about it at all," note Paul Peterson and Mark Rom. The issue of the minimum people need in order to live decently is so difficult that Congress has left this crucial question to the states—even though the federal government foots three-fourths of the bill for about 15 million Americans who receive cash and food stamp benefits. The states differ widely in their assessment of what a family needs to meet a reasonable standard of living, and the interstate differences in welfare benefits cannot be explained by variations in wage levels or costs of living. The states with higher welfare benefits act as magnets by attracting or retaining poor people. In the competition to avoid becoming welfare havens, states have cut welfare benefits in real dollars by more than one-third since 1970. The authors propose the establishment of a minimum federal welfare standard, which would both reduce the interstate variation in welfare benefits and stem their overall decline. Peterson and Rom develop their argument in four steps. First they show how the politics of welfare magnets works in a case study of policymaking in Wisconsin. Second, they present their analysis of the overall magnet effect in American state politics, finding evidence that states with high welfare benefits experiencing disproportionate growth in their poverty rates make deeper welfare cuts. Third, they describe the process by which the current system came into being, identifying the reform efforts and political crises that have contributed to the centralization of welfare policy as well as the regional, partisan, and group interests that have resisted these changes. Finally, the authors propose a practical step that can go a long way toward achieving a national welfare standard; then assess it's cost, benefits, and political feasibility.
