Rapid Facilitation of Ultrasound Production and Lordosis in Female Hamsters by Horizontal Cuts Between the Septum and Preoptic Area

Horizontal cuts between the septum and preoptic area (anterior roof deafferentation, or ARD) dramatically affect sexual behavior, and in ways that could explain a variety of differences across behavioral categories (precopulatory, copulatory), species, and the sexes. Yet little is known about how these effects develop. Such information would be useful generally and could be pivotal in clarifying the mechanism for ultrasonic vocalization in female hamsters. Ultrasounds serve these animals as precopulatory signals that can attract males and help initiate mating. Their rates can be increased by either ARD or lesions of the ventromedial hypothalamus (VMN). If these effects are independent, they would require a mechanism that includes multiple structures and pathways within the forebrain and hypothalamus. However, it currently is not clear if they are independent: VMN lesions could affect vocalization by causing incidental damage to the same fibers targeted by ARD. Fortunately, past studies of VMN lesions have described a response with a very distinctive time course. This raises the possibility of assessing the independence of the two lesion effects by describing just the development of the response to ARD. To accomplish this, female hamsters were observed for levels of ultrasound production and lordosis before and after control surgery or ARD. As expected, both behaviors were facilitated by these cuts. Further, these effects began to appear by two days after surgery and were fully developed by six days. These results extend previous descriptions of the ARD effect by describing its development and time course. In turn, the rapid responses to ARD suggest that these cuts trigger disinhibitory changes in pathways that differ from those affected by VMN lesions. 2013

Market Prices and Food Aid Local and Regional Procurement and Distribution: A Multi-Country Analysis

To date, no research has rigorously addressed the concern that local and regional procurement (LRP) of food aid could affect food prices and food price volatility in food aid source and recipient countries. We assemble spatially and temporally disaggregated data and estimate the relationship between food prices and their volatility and local food aid procurement and distribution across seven countries for several commodities. In most cases, LRP activities have no statistically significant relationship with either local price levels or food price volatility. The few exceptions underscore the importance of market monitoring. (C) 2013 Elsevier Ltd. All rights reserved.

The Timeliness and Cost-Effectiveness of the Local and Regional Procurement of Food Aid

Local and regional procurement (LRP) of food aid is often claimed to lead to quicker and more cost-effective response. We generate timeliness and cost-effectiveness estimates by comparing US-funded LRP activities in nine countries against in-kind, transoceanic food aid shipments from the US to the same countries during the same timeframe. Procuring food locally or distributing cash or vouchers results in a time savings of nearly 14 weeks, a 62 percent gain. Cost-effectiveness varies significantly by commodity type. Procuring grains locally saved over 50 percent, on average, while local procurement of processed commodities was not always cost-effective. (C) 2013 Elsevier Ltd. All rights reserved.

Tradeoffs or Synergies? Assessing Local and Regional Food Aid Procurement through Case Studies in Burkina Faso and Guatemala

We compare the impacts across a range of criteria of local and regional procurement (LRP) relative to transoceanic shipment of food aid in Burkina Faso and Guatemala. We find that neither instrument dominates the other across all criteria in either country, although LRP commonly performs at least as well as transoceanic shipment with respect to timeliness, cost, market price impacts, satisfying recipients' preferences, food quality and safety, and in benefiting smallholder suppliers. LRP is plainly a valuable food assistance tool, but its advantages and disadvantages must be carefully weighed, compared, and prioritized depending on the context and program objectives.

"She Was Not Even Normal": Unreliable Narratives of Female Insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea

In my thesis, I interrogate narrative reliability related to depictions of female insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea. By subjecting the trustworthiness of her storytelling to criticism, especially as regards the concealed madwoman, Bertha Mason, Jane's narration is revealed as unstable, offering problematic insight into a character long considered unflinchingly honest. In du Maurier's later literary adaptation of Jane Eyre, Bertha's parallel character, the eponymous Rebecca, comes to the fore, while the novel's unnamed narrator remains in the shadows, and bases much of her storytelling upon hearsay, rather than the "autobiography" of Jane Eyre. The most transparent narrative voice, however, is Antoinette, the main character of Wide Sargasso Sea, the 1966 prequel to Jane Eyre. Despite her madness, Antoinette's narration makes no attempt at dissemblance, speaking forthrightly about her marriage and experience, proving a truthful narrator and openly rejecting the marginal status the earlier narrators try desperately to hide.

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.

Transport of Hydraulic Fracturing Water and Wastes in the Susquehanna River Basin, Pennsylvania

The development of the Marcellus Shale gas play in Pennsylvania and the northeastern United States has resulted in significant amounts of water and wastes transported by truck over roadways. This study used geographic information systems (GIS) to quantify truck travel distances via both the preferred routes (minimum distance while also favoring higher-order roads) as well as, where available, the likely actual distances for freshwater and waste transport between pertinent locations (e. g., gas wells, treatment facilities, freshwater sources). Results show that truck travel distances in the Susquehanna River Basin are greater than those used in prior life-cycle assessments of tight shale gas. When compared to likely actual transport distances, if policies were instituted to constrain truck travel to the closest destination and higher-order roads, transport mileage reductions of 40-80% could be realized. Using reasonable assumptions of current practices, greenhouse gas (GHG) emissions associated with water and waste hauling were calculated to be 70-157 MT CO2 eq per gas well. Furthermore, empty so-called backhaul trips, such as to freshwater withdrawal sites or returning from deep well injection sites, were found to increase emissions by an additional 30%, underscoring the importance of including return trips in the analysis. The results should inform future life-cycle assessments of tight shale gases in managed watersheds and help local and regional governments plan for impacts of transportation on local infrastructure.

Transnational Marriage: Modern Imaginings, Relational Realignments, and Persistent Inequalities

In the context of shifting cultural anchors as well as unstable global economic conditions, new practices of intimacy and sexuality may become tactics in an individual’s negotiation of conflicting desires and potentials. This article offers reflection on the interface between global forces, powerful transcultural narratives, and state policies, on the one hand, and local, even individual, constructions and tactics in regard to sexuality, marriage, migration, and work, on the other. The article focuses on the life trajectory of Gudiya, an ambitious young Hindu woman who started out life with little social capital and few economic resources in a dusty corner of what was then the tiny kingdom of Nepal. Gudiya’s story highlights the ways in which she has engaged in relational realignments aimed at bringing her closer to the life she imagines, even as she has encountered new and persistent forms of inequality both local and transnational in scale.
