Toward a Global Organic Culture: Ethnographic Perspectives on Wwoofing Practices in Peru and New Zealand

In this thesis, I explore the meaning behind sustainable living among organic farmers and their families in two countries. It is based on original, ethnographic research that I conducted in New Zealand in fall 2012 and Peru in summer 2012 with support from the Department of Sociology and Anthropology Meerwarth Undergraduate Research Fund. In carrying out my research I relied on participant-observation, semi-structured interviews, focus groups, and writing ethnographic fieldnotes. Drawing on contemporary scholarship in the anthropology of food and the environment, my thesis contributes to cross-culturally understandings of sustainability and local and global foodways. Specifically, I will interpret the meaning and significance of my informants’ decision to live sustainably through their participation in wwoofing. The global network of wwoofing aims to connect volunteers interested in learning about organic farming techniques with farmers looking for labor assistance. Volunteers exchange work for food, accommodation, knowledge, and experience. As a method of farming and a subjective ideological orientation, this global movement allows travelers from all over the world to experience organic lifestyles worldwide. In my thesis, I connect my experiences of organic living in Peru and New Zealand. In comparing wwoofing practices in these two field sites, I argue that despite observable differences in organic practices, a global organic culture is emerging. Here I highlight some shared features of this global organic culture, such as food authenticity, sustainability of the earth, and a personal connection of individuals to the land. The global organic culture emphasizes a conscious awareness of what is going into one’s body and why. Using food as an expression of values and beliefs, organic farmers reconnect to the land and their food in attempts to construct an alternative identity. By focusing on food authenticity, my informants develop vast relationships with the land, which shapes their identity and creates new forms of self-enhancement.

Alpine Plants and Climate Change in Glacier National Park, New Zealand and Scotland

The first part of the lecture details a study of how receding glaciers and snowfields in Montana, New Zealand and Scotland affect the alpine plants that grow along and near their edges. Measuring and monitoring techniques are included. The second part describes the Global Observation Research Initiative in Alpine Environments (GLOBAL) whose purpose is "to establish and maintain a world-wide long-term observation network in alpine environments. Vegetation and temperature data collected at the GLORIA sites will be used for discerning trends in species diversity and temperature."

Sexuality and the ‘Relations of Ruling’: Using Institutional Ethnography to Research Lesbian and Gay Foster Care and Adoption.

This article makes use of institutional ethnography to research foster care and adoption by lesbians and gay men, drawing on the work of the feminist sociologist Dorothy E. Smith in order to demonstrate the investigation of social work institutional categories and the ‘relations of ruling’. Through an analysis of the ways in which ‘gender’ and the idea of the ‘gender role model’ is used within the assessment of gay and lesbian foster carers and adopters, the author shows how these categories are produced and used to police relationship forms and to identify ‘deviant instances’.

Extension and Partitioning in an Oblique Subduction Zone, New Zealand: Constraints from Three-Dimensional Numerical Modeling

Contraction, strike slip, and extension displacements along the Hikurangi margin northeast of the North Island of New Zealand coincide with large lateral gradients in material properties. We use a finite- difference code utilizing elastic and elastic-plastic rheologies to build large- scale, three-dimensional numerical models which investigate the influence of material properties on velocity partitioning within oblique subduction zones. Rheological variation in the oblique models is constrained by seismic velocity and attenuation information available for the Hikurangi margin. We compare the effect of weakly versus strongly coupled subduction interfaces on the development of extension and the partitioning of velocity components for orthogonal and oblique convergence and include the effect of ponded sediments beneath the Raukumara Peninsula. Extension and velocity partitioning occur if the subduction interface is weak, but neither develops if the subduction interface is strong. The simple mechanical model incorporating rheological variation based on seismic observations produces kinematics that closely match those published from the Hikurangi margin. These include extension within the Taupo Volcanic Zone, uplift over ponded sediments, and dextral contraction to the south.

Bacterial meningitis: insights into pathogenesis and evaluation of new treatment options: a perspective from experimental studies.

ABSTRACT  Bacterial meningitis is associated with high mortality and morbidity rates. Bacterial components induce an overshooting inflammatory reaction, eventually leading to brain damage. Pathological correlates of neurofunctional deficits include cortical necrosis, damage of the inner ear and hippocampal apoptosis. The hippocampal dentate gyrus is important for memory acquisition and harbors a neuronal stem cell niche, thus being potentially well equipped for regeneration. Adjuvant therapies aimed at decreasing the inflammatory reaction, for example, dexamethasone, and those protecting the brain from injury have been evaluated in animal models of the disease. They include nonbacteriolytic antibiotics (e.g., daptomycin), metalloproteinase inhibitors and modulators of the immunological response, for example, granulocyte colony-stimulating factor. Increasing research interest has recently been focused on interventions aimed at supporting regenerative processes.

Provenance analysis using Raman spectroscopy of carbonaceous material: A case study in the Southern Alps of New Zealand

Detrital provenance analyses in orogenic settings, in which sediments are collected at the outlet of a catchment, have become an important tool to estimate how erosion varies in space and time. Here we present how Raman Spectroscopy on Carbonaceous Material (RSCM) can be used for provenance analysis. RSCM provides an estimate of the peak temperature (RSCM-T) experienced during metamorphism. We show that we can infer modern erosion patterns in a catchment by combining new measurements on detrital sands with previously acquired bedrock data. We focus on the Whataroa catchment in the Southern Alps of New Zealand and exploit the metamorphic gradient that runs parallel to the main drainage direction. To account for potential sampling biases, we also quantify abrasion properties using flume experiments and measure the total organic carbon content in the bedrock that produced the collected sands. Finally, we integrate these parameters into a mass-conservative model. Our results first demonstrate that RSCM-T can be used for detrital studies. Second, we find that spatial variations in tracer concentration and erosion have a first-order control on the RSCM-T distributions, even though our flume experiments reveal that weak lithologies produce substantially more fine particles than do more durable lithologies. This result implies that sand specimens are good proxies for mapping spatial variations in erosion when the bedrock concentration of the target mineral is quantified. The modeling suggests that highest present-day erosion rates (in Whataroa catchment) are not situated at the range front but around 10 km into the mountain belt.

Bedload composition, transport and modification in rivers of Westland, New Zealand, with implications for the distribution of alluvial pounamu (jade)

River bedload surveyed at 50 sites in Westland is dominated by Alpine Schist or Torlesse Greywacke from the Alpine Fault hanging wall, with subordinate Pounamu Ultramafics or footwall-derived Western Province rocks. Tumbling experiments found ultramafics to have the lowest attrition rates, compared with greywacke sandstone and granite (which abrade to produce silt to medium-sand), or incompetent schist (which fragments). Arahura has greater total concentrations (103–105 t/km2) and proportions (5–40%) of ultramafic bedload compared with Hokitika and Taramakau catchments (101–104 t/km2, mostly <10%), matching relative areas of mapped Pounamu Ultramafic bedrock, but enriched relative to absolute areal proportions. Western Province rocks downthrown by the Alpine Fault are under-represented in the bedload. Enriched concentrations of ultramafic bedload decrease rapidly with distance downstream from source rock outcrops, changing near prominent ice-limit moraines. Bedload evolution with transport involves both downstream fining and dilution from tributaries, in a sediment supply regime more strongly influenced by tectonics and the imprint of past glaciation. Treasured New Zealand pounamu (jade) is associated with ultramafic rocks. Chances of discovery vary between catchments, are increased near glacial moraines, and are highest near source-rock outcrops in remote mountain headwaters.
