The hydrology of prehistoric farming systems in a central Arizona ecotone

The prehistoric land use and water management in the semi-arid Southwest was examined. Remote sensing data, geology, hydrology and biology are discussed along with an evaluation of remote sensing contributions, recommendations for applications, and proposed future remote sensing studies

Vygotsky in English: What Still Needs to Be Done

At present readers of English have still limited access to Vygotsky’s writings. Existing translations are marred by mistakes and outright falsifications. Analyses of Vygotsky’s work tend to downplay the collaborative and experimental nature of his research. Several suggestions are made to improve this situation. New translations are certainly needed and new analyses should pay attention to the contextual nature of Vygotsky’s thinking and research practice

Comparing Notes: Recording and Criticism

This chapter charts the ways in which recording has changed the nature of music criticism. It both provides an overview of the history of recording and music criticism, from the advent of Edison’s Phonograph to the present day, and examines the issues arising from this new technology and the consequent transformation of critical thought and practice

Wider Still and Wider: British Music Criticism since the Second World War

This chapter provides the first historical examination of music criticism in Britain since the Second World War. In the process, it also challenges the simplistic prevailing view of this being a period of decline from a golden age in music criticism

Resistance and resilience of periphyton communities as a function of biomass and physiological state.

Periphyton communities were grown under a gradient of resource regimes to obtain a gradient of mat thicknesses and physiological states. All communities were subjected to a simulated flood event to determine if resistance and resilience are inversely related. Resistance was measured as a lack of a significant decrease between pre-disturbance samples and post-disturbance samples of ash free dry mass (AFDM) and chlorophyll a, both measures of biomass. Resilience was measured as a significant increase in biomass (AFDM and chlorophyll a) between the first post-disturbance sampling day and the second post-disturbance sampling day. Trends were found that indicate high nutrient concentrations influence low resistance and high resilience, and low nutrient concentrations influence high resistance and low resilience.http://deepblue.lib.umich.edu/bitstream/2027.42/54493/1/2931.pdfDescription of 2931.pdf : Access restricted to on-site users at the U-M Biological Station

Douglas Lake - comparative lake survey.

Douglas Lake, located in Cheboygan County, Michigan, has been defined as a moderately eutrophic lake (Bazin and Saunders, 1971). The lake was formed during the late glacial period. As the Wisconsin ice sheets receded, seven or more blocks of ice were left buried in the earth where Douglas Lake now exists. The melting of these ice blocks left seven deep basins which led to the formation of the lake. The deepest of these basins is located on the west side of Pells Island. Other deep depressions are located around South Fishtail Bay (24.1 m deep), and the northwest corner of the lake just west of Roberts Point. These deep holes are broken up by broad shoals where the water is shallow, creating a very diverse lake habitat. This type of lake is technically called a kettle hole lake (Welch, 1935).http://deepblue.lib.umich.edu/bitstream/2027.42/54355/1/2791.pdfDescription of 2791.pdf : Access restricted to on-site users at the U-M Biological Station
