The scope of this paper is to describe the work of manual sugarcane harvesters, assessing the nutritional behavior and body composition between the beginning and the end of the harvest. A descriptive longitudinal study was made of harvesters in Piracicaba, São Paulo, Brazil, who answered a socio-demographic questionnaire and authorized measurement of Body Mass Index, Body Fat Percentage and Arm Muscle Circumference at three stages. Creatine kinase on the skeletal isoform, C-reactive protein and plasma urea were measured at the end of the harvest. Thirty male migrant harvesters with ages ranging from 18 to 44 from the Northeast (Ceará) were assessed over a nine-month period. The workers suffered significant body fat and weight loss in the first half of the harvest. Eighteen workers had abnormal levels of creatine kinase and four - out of 24 who had donated blood - had altered urea levels. Sugarcane harvesting work causes weight and body fat loss and gains in the lean body mass index, which suffers wear-out when working on consecutive harvests. It can also cause changes in biochemical markers of chronic systemic inflammation. Further studies will make it possible to comprehend the relationships between stress, wear-out, labor longevity and health in sugarcane harvesting.

[EN] Diel Vertical Migrants (DVMs) are mainly zooplankton and micronekton which migrate upward from 400-500 m depth every night to feed on the productive epipelagic zone, coming back at dawn to the mesopelagic zone, where they defecate, excrete, and respire the ingested carbon. DVMs should contribute to the biological pump in the ocean and, accordingly, to the global CO2 balance. Although those migrants are mainly small fishes, cephalopods and crustaceans, the lanternfishes (myctophidae) usually contribute up to 80% of total DVMs biomass. Thus, myctophids may represent a pathway accounting for a substantial export of organic carbon to the deep ocean. However, the magnitude of this transport is still poorly known. In order to assess this active flux of carbon, we performed a preliminary study of mesopelagic organisms around the Canary Islands. Here we present the results of diet, daily rations and feeding chronology of Lobianchia dofleini, Hygophum hygomii and Ceratoscopelus maderensis, 3 dominant species of myctophids performing diel vertical migrations in the Subtropical Eastern North Atlantic Ocean. Samples were obtained on board the RV La Bocaina during June 2009. Myctophids were sorted and fixed in 4% buffered formalin and the stomach contents of target species were examined and weighted. Feeding chronology was approached by studying stomach fullness and state of digestion of prey items in individuals from hauls performed at different times and depths. Our results provide further information about lanternfishes feeding ecology in relation to their vertical migration patterns as well as their contribution to the biological carbon pump.

[EN] The submarine volcano eruption off El Hierro Island (Canary Islands) on 10 October 2011 promoted dramatic perturbation of the water column leading to changes in the distribution of pelagic fauna. To study the response of the scattering biota, we combined acoustic data with hydrographic profiles and concurrent sea surface turbidity indexes from satellite imagery. We also monitored changes in the plankton and nekton communities through the eruptive and post-eruptive phases. Decrease of oxygen, acidification, rising temperature and deposition of chemicals in shallow waters resulted in a reduction of epipelagic stocks and a disruption of diel vertical migration (nocturnal ascent) of mesopelagic organisms. Furthermore, decreased light levels at depth caused by extinction in the volcanic plume resulted in a significant shallowing of the deep acoustic scattering layer. Once the eruption ceased, the distribution and abundances of the pelagic biota returned to baseline levels. There was no evidence of a volcano-induced bloom in the plankton community.

L’oggetto dell’analisi si situa all’intersezione di diversi ambiti disciplinari: letteratura, scienze dell’educazione, sociologia, psicologia. Nel presente lavoro, viene privilegiata un’analisi tematica della narrativa e la definizione identitaria delle “infanzie migranti” viene declinata seguendo percorsi di lettura che mettano in risalto alcune prospettive ricorrenti nei romanzi. Il corpus letterario selezionato include alcuni romanzi scritti in lingua inglese da sei scrittrici di origine indiana, in particolare Jamila Gavin, Rachna Gilmore, Anjali Banerjee, Rukhsana Khan, Ravinder Randhawa e Meera Syal. Nel primo capitolo si tracciano le premesse teoriche e metodologiche del lavoro, definendo il genere della letteratura per l’infanzia e interrogandoci sulle sue specificità in un contesto postcoloniale qual è quello indiano. Il secondo capitolo è dedicato alla definizione identitaria delle seconde generazioni, in particolar modo di quelle indo-britanniche e indo-canadesi, cui appartengono i protagonisti dei romanzi presi in esame. Nel terzo capitolo viene posta attenzione agli elementi che concorrono alla definizione identitaria dei giovani protagonisti dei romanzi, i quali si interrogano sul loro essere e sull’appartenenza interculturale. I dialoghi intergenerazionali tra i protagonisti e i nonni - o altre figure di guida - permettono alle scrittrici di raccontare la storia dell’India coloniale e della lotta per l’indipendenza dal punto di vista degli esclusi dalla storiografia ufficiale. Nel capitolo conclusivo si argomenta invece come la definizione identitaria si attui per mezzo dello spazio, tramite l’appartenenza ai luoghi, spazi caricati di significato, e per mezzo del viaggio, che può essere reale, immaginario o iniziatico. In tutti i casi, il viaggio porta alla scoperta del Sé, di un’identità ibrida e molteplice da parte dei personaggi.

In this article, I explore how immigrants from the West African nation of Guinea-Bissau living in Portugal use mobile phones in their daily lives in Lisbon. Whereas one might assume that mobile phones and other new information technologies facilitate transnational communication between Africa and Portugal, the ethnographic fieldwork that I conducted in Lisbon from 1999 to 2003 revealed a different scenario. Instead, mobile phones as imagined and used by the Guinean immigrants I met in Lisbon revealed less about transnationalism and globalization than they did about constructing community and identity in a new locale. As Guinean immigrants in Portugal reconfigured their relationship to their former colonizers and struggled to make their way in a new, multicultural Europe, they used their mobile phones to engage local networks, shape local identities, and transform Lisbon's sprawl into an African migrant village. Here, I highlight the gendered dimensions of this process and contend that Guinean men's and women's varied uses of mobile phones in Lisbon underscore contrasting experiences of migration, mobility, and belonging.

In the early decades of the twentieth century, as Japanese society became engulfed in war and increasing nationalism, the majority of Buddhist leaders and institutions capitulated to the status quo. One notable exception to this trend, however, was the Shinkō Bukkyō Seinen Dōmei (Youth League for Revitalizing Buddhism), founded on 5 April 1931. Led by Nichiren Buddhist layman Seno’o Girō and made up of young social activists who were critical of capitalism, internationalist in outlook, and committed to a pan-sectarian and humanist form of Buddhism that would work for social justice and world peace, the league’s motto was “carry the Buddha on your backs and go out into the streets and villages.” This article analyzes the views of the Youth League for Revitalizing Buddhism as found in the religious writings of Seno’o Girō to situate the movement in its social and philosophical context, and to raise the question of the prospects of “radical Buddhism” in twenty-first century Japan and elsewhere.
