The average saving rate for the typical American household before the recession started in 2007 was 2.9 percent; since then it has risen to 5 percent. Uncertainty about the future was the primary driver for the increase. More saving is a good thing, right? Well, some economists argue it might be detrimental to the overall economy. Given the benefits to individuals, how could this be? The May 2012 issue explores this "paradox of thrift."

A refreshing intervention in dance studies, this book brings together elements of historiography, cultural memory, folklore, and dance across comparatively narrow but markedly heterogeneous localities. Rooted in investigations of often newly discovered primary sources, the essays afford many opportunities to compare sociocultural and political reactions to the arrival and practice of popular rotating couple dances, such as the Waltz and the Polka. Leading contributors provide a transnational and affective lens onto strikingly diverse topics, ranging from the evolution of romantic couple dances in Croatia, and Strauss’s visits to Hamburg and Altona in the 1830s, to dance as a tool of cultural preservation and expression in twentieth-century Finland.

The war in Vietnam has been described as the war America watched from their living rooms. Images of combat and American GIs were projected through our TV screens and across our newspapers daily. During the war in Vietnam, the American military gave the press unprecedented freedom of access to combat zones. This allowed newspaper reporters and photographers and television crews to document a war involving American sons and daughters on the other side of the world. This willingness to allow documentation of the war was also extended to the military's own photographers. Between 1962 and 1975, military photographers for the United States Army, Marine Corps, Navy, and Air Force took millions of photographs of the American conflict in Vietnam. Almost a quarter of a million of these images are now located at the National Archives. These photographs serve publishers, historians, and students who want to learn more about Vietnam. They include images of almost every aspect of the war.

In this video, students learn that the Exxon Valdez oil spill in Alaska in 1989 was not the sole cause of the decline of species in the local ecosystem. Rather, an explanation is posited for why some animal populations were already in decline when the spill occurred. Many of these animals share a common food: the sand lance, a fish whose populations have shrunk with the steady rise in ocean temperature that began in the late 1970s.

Two graphs from the NASA Climate website illustrate the change in global surface temperature relative to 1951-1980 average temperatures. The NASA plot is annotated with temperature-impacting historic events, which nicely connect an otherwise challenging graphic to real-world events.

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a great database for student historical research or data and statistics classes. Consider becoming a member or making a donation to help further the work of the site.

This visualization, from the US Geological Survey, provides a simple schematic of the various pathways that water can take as it cycles through ocean, lakes, atmosphere, surface and ground.

Scientific research and design is traditionally made to be published in books or magazines by use of text and images. The arrival of digital media and internet changed this dramatically and allowed new possibilities and far better accessibility of this work. Be this as it may, it is still paramount that the accuracy and completeness of published scientific work is maintained. This course will focus on this integrated concept, the learning of how to successfully make and publish your own website. In 6 lectures the several aspects of traditional scientific research will be treated by using the contemporary media. The course has the following study goals, that correspond with the given assignments and lectures: publishing own study and design work; making your work retrievable for others by use of key words; making use of digital media to describe own work; describing and evaluating of own work; making a bibliography and iconography; intrepretenting an image as a scientific document;describing in key words; compare images scientifically; deducting design types from image comparison; deducting design concepts from image comparison; deducting design models from image comparison; deducting design programs from image comparison; integrating different design concepts and becoming acquainted with research methods; defining an object of research, problem field, target field, design tools, own competence and context of research; formulating a site, context factors, motivation, design program, contribution, intended results and planning; justifying, referring and concluding of own work; giving and receiving professional critique.

This exercise uses Google Streetview, in combination with 360 degree immersive photographs, to show students real-world examples of the sedimentary rocks, sedimentary structures, and weathering processes that they are learning about in class.
Examples are taken from Parfrey's Glen (WI); Zion National Park; Glacier National Park; Starved Rock State Park (IL); Monument Valley; and Grand Staircase - Escalante National Monument.

This video provides history on product development by General Motors and other industries that led to the release of Chlorofluorocarbons (CFCs). It explains the connection between global warming and the ozone hole, chemical build-up in our lower and upper atmospheres, the increase in GWP gases, increased air quality ozone alerts and the 1987 Montreal Protocol that banned the use of CFCs globally.

Is there a recipe for economic growth? Perhaps some Miracle-Gro for the economy? If only it were that easy. While the exact recipe is a mystery, economists have identified some of the key ingredients. The September 2013 issue discusses the role that economic institutions play in fostering long-term economic growth.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

This animation starts with a schematic illustration of glacier growth and then introduces six different methods that researchers use when studying ice cores in order to deduce the climate of the past. The research methods that are briefly introduced are ice layering, pollen, oxygen isotopes, ice crystals and gases trapped inside, and other chemistry.
