Representing and Performing Taste at Wine Festivals: A Somatic, Layered Account
Sensuous scholarship refers to research about the human senses, through the senses, and for the senses. Sensuous scholarship asks us to recognize the meaningfulness of our somatic experience of the world, to understand the skilful activities through which we actively make and remake the world through our senses, and to develop evocative strategies of representation— to write sensuously. In this article, the authors reflect on one particular genre of sensuous scholarship, which they refer to as the somatic layered account. The authors draw upon participant observation data collected at wine festivals at seven sites scattered across western British Columbia and Southern California. The authors examine how people express taste sensations and preferences to others, as well as what role wine’s material properties play in these social dramas. In formulating and developing the concepts of somatic accounts, taste vocabularies, and somatic joint acts, the authors contribute to a growing understanding of the social aspects of the senses and of sensations, as well as how people perceive the material world—and the sense of taste in particular—in active and reflexive ways
Perdas de solo, água, nutrientes e carbono orgânico em Cambissolo e Latossolo sob chuva natural Soil, water, nutrients and organic carbon losses from inceptisol and Oxisol under natural rainfall
A erosão hídrica é responsável por perdas de nutrientes e carbono dos solos agrícolas. A minimização das perdas de solo, água, nutrientes e carbono orgânico constitui importante aspecto do planejamento conservacionista. Os objetivos deste trabalho foram avaliar as perdas, por erosão hídrica, de solo, água, nutrientes e carbono orgânico em Cambissolo Háplico Tb distrófico típico (CXbd) e Latossolo Vermelho distroférrico típico (LVdf). As coletas foram realizadas depois de cada evento de chuva considerada erosiva. As perdas médias anuais de solo foram de 205,65 Mg ha-1 para o CXbd e de 14,90 Mg ha-1 para o LVdf. As perdas médias anuais de água foram 369 mm para o CXbd e 113 mm para o LVdf, representando, respectivamente, 28,67% e 8,78% do total precipitado. Os atributos mineralógicos, químicos e físicos e o relevo de ocorrência desses solos explicam satisfatoriamente os resultados obtidos. O CXbd apresentou as maiores perdas de nutrientes e carbono orgânico. O carbono orgânico foi encontrado em maior quantidade no sedimento erodido, evidenciado pelo caráter seletivo da erosão.<br>Water erosion is responsible for considerable losses of nutrients and organic carbon from agricultural soils. The reduction of soil, water, nutrients and organic carbon losses constitutes an important aspect of the conservation planning. The objectives of this work were to evaluate the soil, water, nutrients and organic carbon losses from a Typic Dystrochept (TD) and a Rhodic Hapludox (RH). The samplings were performed after each considered erosive rain event. The mean annual soil losses were 205.65 Mg ha-1 for the TD and 14.90 Mg ha-1 for the RH. The mean annual water losses were 369 mm for the TD and 113 mm for the RH, representing 28.67% and 8.78% of the total precipitation, respectively. The mineralogical, chemical and physical attributes and the relief where these soils occur satisfactorily explain the obtained results. The TD presents higher nutrients and organic carbon losses than the RH. The organic carbon was the main component of the eroded sediment, evidenced by the selective character of erosion
