Evaluating the Economic Impact of Countervailing Duties on United States Warm Water Shrimp Imports

Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate source country shrimp import data. It was assumed that supply was perfectly elastic and U.S. wholesalers determine the quantities imported from individual countries given the prices and preferences of U.S. consumers. Ex-ante analysis suggests that most countries levied with the countervailing duty experience declines in U.S. import demand while those countries not affected by the countervailing duty experience increases in import demand. Ex-post analysis shows the reverse to be true. Several countries impacted by the countervailing duty had increased import demand from the United States while Mexico, which was not affected by the countervailing duty, had decreased import demand. The results from aggregate level data suggest that imposing duties on specific companies within a country may not be effective if that company is not a monopoly producer or controls a significant share of the shrimp produced in that country.International Relations/Trade,

Evaluation

The importance of evaluation has grown in recent years so that this topic has become the focus of considerable policy and research interest (Oliver, 2000). As new learning technologies emerge there is a need to evaluate how these are used to support an increasingly diverse student population. All staff are now expected to carry out evaluations to account for resources or to justify strategic initiatives. Additionally, for individuals trying to instigate change, evaluation data can be important in providing relevant information to initiate, support and empower change by the “production of knowledge that makes a difference” (Patton, 1997)

High Percentages of Reclaimed Asphalt Affect the Performance of Asphalt Binder

More than 90 percent of the road and highway network in the United States is paved with asphalt concrete. Maintenance and periodic rehabilitation require a continuous supply of aggregates and asphalt binder, both of which are becoming increasingly scarce and expensive. Recycling and reusing these resources can reduce costs and improve sustainability. The most common recyclable material used in road construction is reclaimed asphalt pavement (RAP), which is milled asphalt surface layers that have been removed from existing pavements before new asphalt overlay is placed. Reclaimed asphalt roofing shingles (RAS) are another potential source of asphalt binder.There is growing interest in allowing significantly higher percentages of RAP and RAS in asphalt mixes used on state and local roadways. However, making this change has raised concerns regarding how these composite binders may influence the performance and durability of asphalt mixes, depending on the blends of different virgin and reused binders. Researchers at the UC Pavement Research Center investigated the use of higher percentages of RAP and RAS as a partial replacement for the virgin binder in new asphalt mixes and their effect on pavement performance in California. This research brief summarizes findings from that study.View the NCST Project Webpag

Hippocampal BDNF regulates a shift from flexible, goal-directed to habit memory system function following cocaine abstinence.

The transition from recreational drug use to addiction involves pathological learning processes that support a persistent shift from flexible, goal-directed to habit behavioral control. Here, we examined the molecular mechanisms supporting altered function in hippocampal (HPC) and dorsolateral striatum (DLS) memory systems following abstinence from repeated cocaine. After 3 weeks of cocaine abstinence (experimenter- or self-administered), we tested new behavioral learning in male rats using a dual-solution maze task, which provides an unbiased approach to assess HPC- versus DLS-dependent learning strategies. Dorsal hippocampus (dHPC) and DLS brain tissues were collected after memory testing to identify transcriptional adaptations associated with cocaine-induced shifts in behavioral learning. Our results demonstrate that following prolonged cocaine abstinence rats show a bias toward the use of an inflexible, habit memory system (DLS) in lieu of a more flexible, easily updated memory system involving the HPC. This memory system bias was associated with upregulation and downregulation of brain-derived neurotrophic factor (BDNF) gene expression and transcriptionally permissive histone acetylation (acetylated histone H3, AcH3) in the DLS and dHPC, respectively. Using viral-mediated gene transfer, we overexpressed BDNF in the dHPC during cocaine abstinence and new maze learning. This manipulation restored HPC-dependent behavioral control. These findings provide a system-level understanding of altered plasticity and behavioral learning following cocaine abstinence and inform mechanisms mediating the organization of learning and memory more broadly

Star formation in the large Magellanic cloud

What role the Large Magellanic Cloud (LMC), a dwarf irregular galaxy, plays in understanding infrared luminous galaxies is discussed. There are two main reasons the LMC may prove helpful. One, the LMC is only 55 kpc away, very nearby compared to much rarer high luminosity systems. Second, the environment in the LMC is distinctly different than in the Milky Way, at least those parts of the Milky Way interior to the sun, where most of the studies of massive star formation were concentrated. The LMC is an interacting system with a large amount of neutral hydrogen that is pushed around by the galaxy's encounter with the Milky Way. Perhaps a good understanding of star formation process in the LMC will provide guidance in the study of the infrared luminous galaxies. Two questions which will be addressed are: how is star formation in the LMC similar to the Milky Way Galaxy, and how is it different

Custom and habit(us): The meaning of traditions and legends in early medieval western Britain

This a post-print, author-produced version of an article accepted for publication in Geografiska Annaler, Series B: Human Geography. Copyright © Blackwell publishing 1999. The definitive version is available at www.blackwell-synergy.comThis paper discusses some well-known legends and hagiographic stories, and explores the context of their production and consumption. From an examination of Welsh foundation legends and Cornish hagiographical accounts, we focus on the methods by which versions of history were used in the Middle Ages to provide a context for fundamental changes in the way in which society was organised. It is found that, far from abandoning traditional versions of history, accounts of the past were promoted that sought to couch newer territorial notions of organisation within existing constructions of identity and mediations with the past. In an examination of the production and reception of these popular stories, we attempt to relate the legends to the generation of communal identity and memory. Consequently, drawing on Bourdieu's notion of habitus, we argue that pre-existing beliefs and customs were an important part in the development of newer institutional structures. Rather than initiating new practices that had no grounding in any particular past, institutional developments gained social currency by being inherently grounded in existing facets of cultural identity. In essence therefore, changing societal and institutional structures were unintentionally couched in the language and understandings of existing structures, so that in many ways a concept of continuity was at the very heart of actual change

Challenge accepted: Women claiming leadership in higher education learning and teaching

A recognised challenge for women in higher education learning and teaching is of rightfully claiming leadership. Higher education processes for recruitment, promotion, awards, grants and fellowship are founded on an ability to document and convincingly present one’s leadership contribution. The focus is on evidencing from a traditional, formal positional role view of leadership. However, the leadership contribution of women to learning and teaching often accords with a more distributed leadership approach. This may lead to women, unguided in how to evidence their leadership contribution and impact, being unable to self-acknowledge and claim their leadership contribution. The challenge for women is in claiming their leadership contribution and impact so as not to be disadvantaged in academic career progression and recognition. Drawing on a database of 15 years of research into a distributed leadership in learning and teaching, a Linguistics Inquiry approach is employed to explore reflections of female academics to their leadership contributions in learning and teaching. This reveals evidence-based strategies that have successfully supported a positive transition, by women, to self-acknowledge their leadership contributions. Many of these are resource intensive and difficult to sustain in the current higher education sector context of diminishing and reduced resources. To present a low-resource alternative, the six tenets of a Distributed Leadership approach structure a low-resource framework alternative that provides key conceptual prompts for presenting a leadership case. Vignettes of applying the framework in practice are provided to illustrate its transferability across a range of scenarios for women to rightfully claim their leadership contribution
