Non-Fermi liquid fixed point for an imbalanced gas of fermions in 1+ϵ1+\epsilon dimensions

We consider a gas of two species of fermions with population imbalance. Using the renormalization group in $d=1+\epsilon$ dimensions, we show that for spinless fermions and $\epsilon > 0$ a fixed point appears at finite attractive coupling where the quasiparticle residue vanishes, and identify this with the transition to Larkin--Ovchinnikov--Fulde--Ferrell order (inhomogeneous superconductivity). When the two species of fermions also carry spin degrees of freedom we find a fixed point indicating a transition to spin density wave order.Comment: 4 pages and 4 figure

The U.S. Gulf of Mexico Pink Shrimp, Farfantepenaeus duorarum, Fishery: 50 Years of Commercial Catch Statistics

U.S. Gulf of Mexico, pink shrimp, Farfantepenaeus duorarum, catch statistics have been collected by NOAA’s National Marine Fisheries Service, or its predecessor agency, for over 50 years. Recent events, including hurricanes and oil spills within the ecosystem of the fishery, have shown that documentation of these catch data is of primary importance. Fishing effort for this stock has fluctuated over the 50-year period analyzed, ranging from 3,376 to 31,900 days fished, with the most recent years on record, 2008 and 2009, exhibiting declines up to 90% relative to the high levels recorded in the mid 1990’s. Our quantification of F. duorarum landings and catch rates (CPUE) indicates catch have been below the long-term average of about 12 million lb for all of the last 10 years on record. In contrast to catch and effort, catch rates have increased in recent years, with record CPUE levels measured in 2008 and 2009, of 1,340 and 1,144 lb per day fished, respectively. Our regression results revealed catch was dependent upon fishing effort (F=98.48df=1, 48, p<0.001, r2=0.67), (Catch=1,623,378 + (520) × (effort)). High CPUE’s measured indicate stocks were not in decline prior to 2009, despite the decline in catch. The decrease in catch is attributed in large part to low effort levels caused by economical and not biological or habitat related conditions. Future stock assessments using these baseline data will provide further insights and management advice concerning the Gulf of Mexi

Travel for Transformation: Embracing a Counter-Hegemonic Approach to Transformative Learning in Study Abroad

This article reviews literature from 2006-2016 on study abroad (and other forms of travel) to investigate frameworks that create the best plausible opportunities for transformative learning within study-abroad experiences. According to the literature reviewed, in order to be considered travel for transformation, the travel experience must respect the values and knowledge of the host culture, acknowledge the presence of differences in privilege among study-abroad participants, and utilize environmentally sustainable practices. In addition, the duration, purpose of travel, and degree of immersion plays a significant role in perspective transformation. A repeated benefit to study-abroad programs among the articles indicate that study abroad is better positioned for transformative learning than the traditional classroom environment is that it situates the student in a new context where the place, culture, people, and hopefully the language are “other.” While almost all of the literature reviewed for this article included cautions to avoid essentializing and exploiting the host culture, very little could be found on the possible negative outcomes to participants—and especially the host culture—when students from the United States study in other contexts. Therefore, the author recommends that future research investigate the possibility of study abroad as exploitation of both the host culture and the participants of the study-abroad program

L’Evolution du métier d’enseignant de langue de spécialité – une perspective internationale

A travers l’Europe, les professeurs de langues vivantes doivent affronter les mêmes défis : parmi ceux-ci, nous passerons en revue (1) le contexte britannique : l’apprentissage des langues vivantes dans les universités (étudiants spécialistes et non-spécialistes, cours pour adultes) et dans le secondaire, les échanges et le séjour à l’étranger ; (2) le contexte international : le processus de Bologne (interculturalité et employabilité), la markétisation de l’enseignement supérieur, les droits d’inscription, l’anglicisation des programmes ; (3) le contexte technologique : les TIC dans la société et dans l’apprentissage des langues
