Ethnography and Modern Languages

While rarely explicitly recognized in our disciplinary frameworks, the openness and curiosity on which Modern Languages in the UK is founded are, in many ways, ethnographic impulses. Ethnographic theories and practices can be transformative in relation to the undergraduate curriculum, providing an unparalleled model for experiential and holistic approaches to language and cultural learning. As a form of emplaced and embodied knowledge production, ethnography promotes greater reflexivity on our geographical and historical locations as researchers, and on the languages and cultures through which we engage. An ethnographic sensitivity encourages an openness to less hierarchical and hegemonic forms of knowledge, particularly when consciously seeking to invert the traditional colonial ethnographic project and envision instead more participatory and collaborative models of engagement. Modern Languages scholars are at the same time ideally placed to challenge a monolingual mindset and an insensitivity to language-related questions in existing ethnographic research located in cognate disciplines. For Modern Languages to embrace ethnography with credibility, we propose a series of recommendations to mobilize these new research and professional agendas

Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin

Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments. The aim of this study is to analyze the natural diet of Trichodactylus kensleyi of subtropical rainforest streams and corroborate the temporal variation in the trophic activity during day hours. Results: A total of 15 major taxonomic groups were recognized in gut contents. The index of relative importance identified the following main prey items in decreasing order of importance: vegetal remains, oligochaetes, chironomid larvae, and algae. A significant difference was found in the amount of full stomachs during day hours showing a less trophic activity at midday and afternoon. The index of relative importance values evidenced the consumption of different prey according to day moments. Results of the gut content indicate that T. kensleyi is an omnivorous crab like other trichodactylid species. Opportunistic behavior is revealed by the ingestion of organisms abundant in streams such as oligochaetes and chironomid larvae. The consumption of allochthonous plant debris shows the importance of this crab as shredder in subtropical streams. However, the effective assimilation of plant matter is yet unknown in trichodactylid crabs. Conclusions: This research provides knowledge that complements previous studies about trophic relationships of trichodactylid crabs and supported the importance of T. kensleyi in the transference of energy and matter from benthic community and riparian sources to superior trophic levels using both macro- and microfauna.Fil: Williner, Verónica.

‘Sometimes there’s racism towards the French here’: xenophobic microaggressions in pre-2016 London as articulations of symbolic violence

This article discusses xenophobic microaggressions (Pierce, 1970) experienced by members of the French community in London prior to the EU-Membership Referendum in 2016. Acting at the interface of agency and passivity, implicitness and complicity, they go unseen in the social space despite their omnipresence. Through a close reading of empirical data collected as part of an ethnographic study, the article posits that these microaggressions are articulations of historically embedded anti-French ‘symbolic violence’ (Bourdieu and Wacquant, 1992; Bourdieu, 1993). The three main areas addressed are humour, intersectionality and the reproductive nature of the phenomenon (Bourdieu and Passeron, 1970; Bourdieu, 1972)

Feeding Behaviour, Swimming Activity and Boldness Explain Variation in Feed Intake and Growth of Sole (Solea solea) Reared in Captivity

The major economic constraint for culturing sole (Solea solea) is its slow and variable growth. The objective was to study the relationship between feed intake/efficiency, growth, and (non-) feeding behaviour of sole. Sixteen juveniles with an average (SD) growth of 2.7 (1.9) g/kg0.8/d were selected on their growth during a 4-week period in which they were housed communally with 84 other fish. Selected fish were housed individually during a second 4-week period to measure individual feed intake, growth, and behaviour. Fish were hand-fed three times a day during the dark phase of the day until apparent satiation. During six different days, behaviour was recorded twice daily during 3 minutes by direct observations. Total swimming activity, frequency of burying and of escapes were recorded. At the beginning and end of the growth period, two sequential behavioural tests were performed: “Novel Environment” and “Light Avoidance”. Fish housed individually still exhibited pronounced variation in feed intake (CV = 23%), growth (CV = 25%) and behavior (CV = 100%). Differences in feed intake account for 79% of the observed individual differences in growth of sole. Fish with higher variation in feed intake between days and between meals within days had significantly a lower total feed intake (r = −0.65 and r = −0.77) and growth. Active fish showed significantly higher feed intake (r = 0.66) and growth (r = 0.58). Boldness during both challenge tests was related to fast growth: (1) fish which reacted with a lower latency time to swim in a novel environment had significantly higher feed intake (r = −0.55) and growth (r = −0.66); (2) fish escaping during the light avoidance test tended to show higher feed intake (P<0.1) and had higher growth (P<0.05). In conclusion, feeding consistency, swimming activity in the tank, and boldness during behavioral tests are related to feed intake and growth of sole in captivity

Protein requirement of tambaqui juveniles (Colossoma macropomum) after feed deprivation

The aim of this work was evaluate protein requirement of tambaqui (Colossoma macropomum) juveniles after feed deprivation. During 60 days, fish (50,3 ± 0,26 g) were fed on four isoenergetics diets with different protein content (28, 32, 36 and 40% crude protein) at two feeding regimes (with and without feed deprivation) under completely random factorial design (4x2) in triplicate. Water quality parameters and performance index were evaluated at 1º, 15º and 60º days. Water quality parameters were kept at normal fish cultivation patterns. No mortality in the tested treatments. There were observed differences among treatments for performance indexes analyzed: growth rate, feed efficiency, daily feed consumption, crude protein consumption, efficiency protein rate and relative weight gain, except for hepatosomatic index. Hyperfagia was detected indicating the occurrence of compensatory growth. Fat content and body protein deposition increased in fishes refed on 36% of crude protein. These results explain some data observed belong the experiment like the increase of weight gain, of the hyperfagia time extension, of the growth rate and of the feed efficiency. Therefore those fish shows increase on weight gain, hyperfagia time, growth rate and feed efficiency. There is no influence of feed deprivation on protein requirement tambaqui juveniles.O objetivo deste trabalho foi avaliar a exigência protéica de juvenis de tambaqui (Colossoma macropomum) após a privação alimentar. Os peixes (50,3 ± 0,26g) foram submetidos a quatro rações isoenergéticas com diferentes concentrações protéicas (28, 32, 36 e 40% proteína bruta) e dois regimes alimentares (com privação e sem privação) durante 60 dias. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 4x2, em triplicata. Avaliaram-se os parâmetros de qualidade de água e de desempenho no 1º, 15º e 60º dia de experimento. Os parâmetros da qualidade da água permaneceram dentro dos padrões de cultivo. Não houve mortalidade nos tratamentos testados. Foram observados diferenças entre os tratamentos para os índices de desempenho analisadostaxa de crescimento específico, eficiência alimentar, consumo diário de ração, consumo de proteína bruta, taxa de eficiência protéica e ganho de peso relativo, com exceção do índice hepatossomático. Houve hiperfagia, indicando a existência de crescimento compensatório. Os peixes realimentados com 36% proteína bruta tiveram incremento no teor de gordura visceral e maior deposição de proteína corporal. Estes resultados explicam uma melhora nos dados de ganho de peso, duração da hiperfagia, taxa de crescimento e eficiência alimentar. A privação alimentar não influencia a exigência protéica em juvenis de tambaqui
