Exhibit: "Michigan-I-O": Alan Lomax and the 1938 Library of Congress Folk-Song Expedition"

In 1938, a young folk music collector named Alan Lomax—destined to become one of the legendary folklorists of the 20th century recorded Michigan’s richly varied folk music traditions for the Archive of American Folk-Song at the Library of Congress. Michigan in the 1930s was experiencing a golden age of folksong collecting, as local folklorists mined the trove of ballads remembered by aging lumbermen and Great Lakes schoonermen. In addition to the ballads of these north woods singers, Lomax recorded a vibrant mix of ethnic music from Detroit to the western Upper Peninsula. The multimedia performance event Folksongs from Michigan-i-o combines live performance with historic images, color movie footage, and recorded sound from the Great Depression. Some of these materials haven’t been heard or seen by the general public for more than seven decades. The traveling exhibition Michigan Folksong Legacy: Grand Discoveries from the Great Depression brings Alan Lomax’s 1938 field trip to life through words, song lyrics, photographs, and sound recordings. Ten interpretive banners explore themes and each panel contains a QR code that links to related sound recordings from the Alan Lomax Collection at the American Folklife Center, Library of Congress.

A dose-response analysis of a school-based nutrition intervention in middle school children

Childhood obesity in the US has reached epidemic proportions. Minority children are affected the most by this epidemic. Although there is no clear relationship between obesity and fruits and vegetables consumption, studies suggest that eating fruits and vegetables could be helpful in preventing childhood obesity. A few school-based interventions targeting youth have been effective at increasing fruits and vegetables intake.^ In Austin, Texas, the Sustainable Food Center delivered the Sprouting Healthy Kids (SHK) program that targeted low socio-economic status children in four intervention middle schools. The SHK program delivered six intervention components. This school-based intervention included: a cafeteria component, in-class lessons, an after-school garden program, a field trip to a local farm, food tasting, and farmers' visits to schools. This study aimed to determine the effects of the SHK intervention in middle school students' preferences, motivation, knowledge, and self-efficacy towards fruits and vegetables intake, as well as the actual fruits and vegetables intake. The study also aimed to determine the effects of exposure to different doses of the SHK intervention on participants' fruits and vegetable intake.^ The SHK was delivered during Spring 2009. A total of 214 students completed the pre-and-posttest surveys measuring self-report fruits and vegetables intake as well as intrapersonal factors. The results showed that the school cafeteria, the food tasting, the after school program, and the farmers' visits had a positive effect on the participants' motivation, knowledge, and self-efficacy towards fruits and vegetables intake. The farmers' visits and the food tasting components increased participants' fruits and vegetables intake. Exposure to two or more intervention components increased participants' fruits and vegetables intake. The statistically significant dose-response effect size was .352, which suggests that each intervention component increased participants' fruits and vegetables consumption this amount. Certain intervention components were more effective than others. Food tasting and farmers visits increased participants fruits and vegetables intake, therefore these components should be offered in an ongoing basis. This study suggests that exposure to multiple intervention components increased behaviors and attitudes towards fruits and vegetables consumption. Findings are consistent that SHK can influence behaviors of middle school students.^

Glacier mass balance measurements on Fourcade and Polar Club glacier, King George Island

The east coast of the AP is highly influenced by cold and dry air masses stemming from the adjacent Weddell Sea. By the contrary, the west coast jointly with the South Shetland Islands are directly exposed to the humid and relatively warm air masses from the South Pacific Ocean carried by the strong and persistent westerly winds. Systematic glaciological field studies are very scarce on both sides of the AP, among them can be mentioned a mass-balance program performed continuously since summer 1998/99 by the Instituto Antártico Argentino (IAA) on Vega Island, James Ross Archipelago, on the northeastern flank of the AP. Another continuous plurianual glaciological research has been initiated in 2010 jointly by the University of Bonn and the IAA at the Fourcade Glacier on King George Island (KGI) within the framework of the ESF project IMCOAST (FK 03F0617B). Two transects of mass balance stakes were installed from the top of the Warszawa Ice Dome down to the border of the glaciers Fourcade and Polar Club, to serve for calibration and validation of modeling efforts. The stakes were measured at the beginning and end of each summer field campaign in November 2010, February - March 2011, January - March 2012, and especially during the austral winter 2012 up to March 2013 every 10 to 14 days depending on weather conditions. During the austral winter 2013 and until June 2014 the measurements were conducted every 20 to 30 days, weather permitting. Snow density was measured as well in every field trip from June 2012 until June 2104, establishing a rather homogeneous value along the different parts of the glacier. Snow density in late summer, rho_s is usually higher than the one in late winter, rho_w. Seasonal average values were calculated for the area covered by the mass balance stakes, being rho_s= 471 Kg/m**3 and rho_w = 363 Kg/m**3.

Mapa de susceptibilidad a la caída de bloques en la sierra de la Cabrera (Madrid)

El objetivo de este proyecto es el estudio y creación de un mapa de susceptibilidad al alcance por caída de bloques en la Sierra de la Cabrera, provincia de Madrid. Por lo cual se ha realizado, primero, un reconocimiento de campo in situ y, a continuación, un estudio morfométrico del área, empleando sistemas de información geográfica (ArcGIS), así como un análisis cualitativo de las características estructurales de las discontinuidades seleccionando aquellas más determinantes para favorecer el desprendimiento de un bloque rocoso y aportar la información suficiente que permita evaluar la susceptibilidad. El análisis se ha llevado a cabo partiendo de los datos estructurales obtenidos en campo y cotejados con los realizados en otros trabajos. Así se han podido delimitar distintas áreas fuente, donde se puede producir el desprendimiento, y el perímetro de alcance a través de un modelo geométrico. A partir de este modelo, se determinarán las zonas de posible afección, generando una cartografía de susceptibilidad para el área de estudio. ABSTRACT The aim of this project is to study and create a susceptibility map of rockfalling reach in the Sierra de la Cabrera, Madrid. To achieve this goal it is been made, firstly, a field trip and, then, a morphometric study of the area, using geographic information systems (ArcGIS), and also a qualitative analysis of the structural characteristics of the discontinuities choosing those decisives contributing to the rock block’s detach and to provide enough information to evaluate the susceptibility. The analysis is been carried out using structural data got on field and from other studies. In this way, there have been defined different source areas, where rockfalling can occur, and a reaching perimeter using a geometric model. For this model, affected areas can be established and a susceptibility map can be created for the studied area.

Transnistrian Conflict after 20 years: A Report by an International Expert Group. OSW Report, October 2011

The present report is the result of an initiative put forward in 2010 by the Soros Foundation Moldova (East East: Partnership Beyond Borders Program) with the aim of attracting new foreign expertise to provide a fresh look at the ‘frozen conflict’ in the Republic of Moldova. The initiative was informed by the conviction that the political shifts in and around Moldova that have occurred since 2009 are creating new opportunities to resolve the conflict. The idea was to convene a joint group of international and Moldovan experts who, after conducting a fact-finding field trip to Chisinau and Tiraspol and conducting extensive discussions, would draw up a report with their analysis of the situation and their political recommendations.

Sedimentology of a Middle Jurassic Base-of-Slope environment, Cutri Formation, Mallorca

The Cutri Formation’s, type location, exposed in the NW of Mallorca, Spain has previously been described by Álvaro et al., (1989) and further interpreted by Abbots (1989) unpublished PhD thesis as a base-of-slope carbonate apron. Incorporating new field and laboratory analysis this paper enhances this interpretation. From this analysis, it can be shown without reasonable doubt that the Cutri Formation was deposited in a carbonate base-of-slope environment on the palaeowindward side of a Mid-Jurassic Tethyan platform. Key evidence such as laterally extensive exposures, abundant deposits of calciturbidtes and debris flows amongst hemipelagic deposits strongly support this interpretation.
