Mental Disorders in Megacities: Findings from the Sao Paulo Megacity Mental Health Survey, Brazil

Background: World population growth is projected to be concentrated in megacities, with increases in social inequality and urbanization-associated stress. Sao Paulo Metropolitan Area (SPMA) provides a forewarning of the burden of mental disorders in urban settings in developing world. The aim of this study is to estimate prevalence, severity, and treatment of recently active DSM-IV mental disorders. We examined socio-demographic correlates, aspects of urban living such as internal migration, exposure to violence, and neighborhood-level social deprivation with 12-month mental disorders. Methods and Results: A representative cross-sectional household sample of 5,037 adults was interviewed face-to-face using the WHO Composite International Diagnostic Interview (CIDI), to generate diagnoses of DSM-IV mental disorders within 12 months of interview, disorder severity, and treatment. Administrative data on neighborhood social deprivation were gathered. Multiple logistic regression was used to evaluate individual and contextual correlates of disorders, severity, and treatment. Around thirty percent of respondents reported a 12-month disorder, with an even distribution across severity levels. Anxiety disorders were the most common disorders (affecting 19.9%), followed by mood (11%), impulse-control (4.3%), and substance use (3.6%) disorders. Exposure to crime was associated with all four types of disorder. Migrants had low prevalence of all four types compared to stable residents. High urbanicity was associated with impulse-control disorders and high social deprivation with substance use disorders. Vulnerable subgroups were observed: women and migrant men living in most deprived areas. Only one-third of serious cases had received treatment in the previous year. Discussion: Adults living in Sao Paulo megacity had prevalence of mental disorders at greater levels than similar surveys conducted in other areas of the world. Integration of mental health promotion and care into the rapidly expanding Brazilian primary health system should be strengthened. This strategy might become a model for poorly resourced and highly populated developing countries.

The genus Nanopterodectes Mironov, 2009 (Acari, Proctophyllodidae), with descriptions of three new species from antbirds (Passeriformes: Thamnophilidae) in Brazil

Three new species of the recently discovered, and hitherto monotypic, feather mite genus Nanopterodectes Mironov, 2009 are described: N. acutirostris n. sp. from Stymphalornis acutirostris Bornschein, Reinert & Teixeira, N. mentalis n. sp. from Dysithamnus mentalis (Temminck), and N. leucopterus n. sp. from Pyriglena leucoptera (Vieillot). This feather mite genus is currently restricted to passerine birds of the Neotropical family Thamnophilidae in Brazil. A key to the known species of Nanopterodectes is presented for both sexes.

Zooplankton, micronekton and biological pump: Beyond the mesopelagic zone

[EN] Migrant biota transports carbon to the mesopelagic zone due to their feeding at the shallower layers and their defecation, respiration, excretion and mortality at depth. The so-called active flux has been considered a small number compared to gravitational sinking. Recent assessments in subtropical waters show an important effect due to predation by interzonal diel vertical migrants (DVMs). The consumption and subsequent transport of epipelagic zooplankton by DVMs (mainly micronekton) to the mesopelagic zone seemed similar to the mean gravitational export. However, the consequences of this active transport to the bathypelagic zone are almost unknown. Here, we show the effect of the Atlantic and Pacific equatorial upwelling systems on the vertical distribution of acoustic backscatter from the surface to bathypelagic depths. The enhancement of the acoustic signal below the upwelling zone was observed to reach 4000 m depth, coinciding with high abundances and activity of bacteria at those depths. The results suggest an active carbon transport from the epipelagic driven by zooplankton and micronekton, enhancing the efficiency of the biological pump and giving an insight about the fate of an increased productivity at the shallower layers of the ocean

Carbon dynamics within cyclonic eddies: Insights from a biomarker study

[EN] It is generally assumed that episodic nutrient pulses by cyclonic eddies into surface waters support a significant fraction of the primary production in subtropical low-nutrient environments in the northern hemisphere. However, contradictory results related to the influence of eddies on particulate organic carbon (POC) export have been reported. As a step toward understanding the complex mechanisms that control export of material within eddies, we present here results from a sediment trap mooring deployed within the path of cyclonic eddies generated near the Canary Islands over a 1.5-year period. We find that, during summer and autumn (when surface stratification is stronger, eddies are more intense, and a relative enrichment in CaCO3 forming organisms occurs), POC export to the deep ocean was 2–4 times higher than observed for the rest of the year. On the contrary, during winter and spring (when mixing is strongest and the seasonal phytoplankton bloom occurs), no significant enhancement of POC export associated with eddies was observed. Our biomarker results suggest that a large fraction of the material exported from surface waters during the late-winter bloom is either recycled in the mesopelagic zone or bypassed by migrant zooplankton to the deep scattering layer, where it would disaggregate to smaller particles or be excreted as dissolved organic carbon. Cyclonic eddies, however, would enhance carbon export below 1000 m depth during the summer stratification period, when eddies are more intense and frequent, highlighting the important role of eddies and their different biological communities on the regional carbon cycle.

Donne migranti a Modena: il lavoro di "badante" tra vincolo e risorsa

This study enters the world of migrants women daily involved in the work of caregiving to elderly people in Modena. The multidimensional analysis that characterizes this work brings together elements which are examined, simultaneously, as bounds and/or opportunities within the migratory experience of these women. The interviews collected will be analyzed in parallel and linked to the international debates on contemporary migrations: the meaning of transnational migrations, the role of the networks in guiding integration, the limits and strengths of multiculturalist theories, the concept of ‘superdiversity’, the link among entitlement, rights and access to citizenship. The present study place at the centre of its observation the “daily practices” that allow every migrant to negotiate its ‘power’, its ‘freedom’ and its ‘rights’, so as to recognize agency to these women in the creation of their strategies and social boundaries. Moreover, the study focuses on the ability and power of the State, and its institutions, to create categorizations among migrants based on their social and economic ‘usefulness’, which produce effects in the daily lives of these workers.

Minori rumeni tra percorsi migratori e rappresentazioni. Nè soli, nè accompagnati a Bologna

The thesis deals with the heterogenous category of the “unaccompanied minors”, concentrating the scientific work on those who migrate from Romania to the Italian city of Bologna. Between different migratory routes that include Romanian minors, I chose to explore the ones linked with the underground and illegal contexts. In order to analyse the reasons and the morphology of their migratory career, I used the multisituated field research which allowed me to consider the social policies in both the Romanian and the Italian environment. The main debate on the situation of the “unaccompanied children” refers to the extent to which these minors leave their country of origin “accompanied” by different adult figures and it also involves the role played by these adults. The first chapter is dedicated to a brief theoretical and methodological introduction to the main arguments of the thesis such as Romanian migration to Italy, trafficking in human beings, transnationality of migrant’s migration and decentered cooperation as a means of contrasting illegal migration and trafficking. Each field of research is characterized by a specific methodological approach, but they are all linked by the anthropological perspective I adopted throughout the entire work. The Romanian context, analized from a diachronic and a synchronic perspective represents the object of the second chapter. Some aspects of the Regime policies and other characteristics of the Romanian poscomunist period of “transition” are useful frameworks that become a background of the migration flows outside the country. The third chapter focuses on the Romanian patterns of migration. The reconstruction of some past attitudes that Romanians adopted towards migration are relevant in order to reveal the continuity with the present migratory practices. A consistent part is dedicated to a concrete example based on a field research in Bologna on a group of Romanian roma migrating from the south of Romania. The contact with these persons opened a debate on the limits between legal and illegal migration practices among the Romanians. The conclusion is that minors’ migration to Italy follows the adult patterns and flows. The nucleus of the field researches is included in the fourth and the fifth chapter. Before presenting the settings and the itineraries of the field researches, some deconstructive reflections are made on the representations that common sense and social sciences create on concepts as “child”, “minor” and “childhood”. A first perspective on the Romanian migrant minors emerges from a research concentrated on a group of roma teenagers engaged in Bologna in activities like windscreen washing, pocket-picking, begging and street prostitution. The aim of the research was to gain access to their daily life, to observe their relationship with the adults who “accompany” them and the strategies they activate in order to take some material profit out of their migratory experience. A parallel field research focuses on the Romanian minors who are part of the roma group coming from the south of Romania. Most of them are reunited with their family in Bologna, but according to the Italian law, they are all living as illegal migrants. Others are only temporary sheltered by these families and they meanwhile dedicate to illegal survviving practices. An interesting point of my participant observation was to reveal the motivations that these minors give when asked about the refusal to start a legal career inside the local Centres dedicated to the “non accompanied minors”. Their autoreflexivity brings some light on the controversy regarding the adequacy of the local and national care system and the migratory projects the minors have. In this respect, a small part of the research is dedicated to the phenomena of minors’ street prostitution in Bologna, as a useful contribution to the fragmented vision researchers have on the “unaccompanied” or “separated” children. The last chapter focuses on a decentered cooperation project that emerged as an alternative response the local administration from Bologna had chosen for facing the presence of numerous migrants coming from the south of Romania. The group of Romanian roma who was also the object of my field research became the starting point for the cooperation proposals between the city of Bologna and the city of Craiova. Although there are three projects involving the two administrations, throughout a period of stage in the Romanian city of Craiova I chose to analyse, only the one dedicated to the “urgent measures” requested in order to contrast the illegal migration and the trafficking in minors. This final part of the thesis highlightens the possible contribution that such a project might bring to the study of a complex and in some parts contradictory phenomena as that of the “unaccompanied” migrant minors.

Rimesse e sviluppo locale nel sistema migratorio del Golfo Persico

The thesis concerns, from an economic and institutional point of view, the migration process in connection with development issues, focusing on the Middle East and North Africa region. Adopting a south-south perspective of migration flows, which is focusing on migration from the Maghreb and Mashreq towards the GCC, the research focuses on the linkage between migration and local development (LED), considering the economic implication that temporary migration flows (trough physical and human capital accumulation) have for the labour exporting countries of the region. Since south-south migration flows are both temporary and skilled, the research points out that return migrants from the GCC can have a significant impact for the growth of recipient countries, as they transfer capital through remittances on regular basis and, once back, they can use human capital acquired abroad to promote economic initiatives. Starting from the descriptive analysis on international migration flows (from an historical to a systemic point of view), and focusing on the patterns of people movements in the Gulf Migration System and on the role remittances have in the region as a strategy for both household survival and local development, the research considers the economics of migrant remittances from a micro and macro perspective and the main direct and indirect effects that remittances have on the local communities. The review of the economic literature on international remittances and on local development shows how migration is an alternative strategy of financing local economic development (LED) especially for low-middle income countries (among them the Maghreb countries). The linkage between return migration, remittances, human capital formation and the promotion of local development in the Egyptian case is the focus of the empirical investigation.

Da una sponda all'altra del Mediterraneo: percorsi migratori femminili

Until the end of the 1970s international migrants were perceived and analysed mainly within the frame of their lives in the host country, or as managing their lives and choices caught in a dilemma “between two cultures”. More recently, this approach has been challenged by an image of diasporic communities composed of individuals who “have collective homes away from home”. Migrants have become icons of hybridity and the metaphor of “border crossing”, the symbol of liberatory articulations between place, culture and identity. Migrants, it is also argued, have become transnational as they manage to live simultaneously in two countries. The research has the aim to study the migration process of the women who come from North Africa to Bologna. In particular, it investigates migrant women‘s relations with their adopted country and how their cultural practices are shaped by the transnational dimension of their lives. It was studied the journey of the migrant women’s lives across two countries and how their identities are going to change because of the experience of the migration. Migrant women are engaged in various kinds of practices and experiences through which they connect their country of origin and of residence. So this research focuses on the changes in the migrant women’s lives and the construction of their new identity. In particular, the research illustrates the development of a new notion of modernity, underlining how the migrant women construct a model of modernity that expresses a constant negotiation among diverse cultural models. The notion of modernity is not produced in opposition to tradition and religion, but is articulated with them in complex and diverse ways. The multiple ways in which migrant women understand modernity reflect their divergent identity’s renegotiation processes within the new society where they live.

Appartenenze, identità e ruoli di genere negli adolescenti di origine immigrata. Uno studio qualitativo nel territorio di Monza e della Brianza

Starting from the contexts on which the researches about migrant minors and adolescents have been concentrated so far, school, free time, friends, family, society integration, this work puts attention on gender dimension, supporting the ideas that socialization is a life-long process, that gender and gender roles are a cultural construction and the subject has multiple identities. The research aim to understand if being male or female, related with ethnic and cultural origin, influences the identity construction, the gender belonging and roles, the behaviours, in a different way, in interaction with the different everyday contexts. The research points out how being male or female affects: - daily choices, expectations and behaviours inside peer group, family and school; - future expectations as adult inside family, work and society; - idea about the adolescence and the self-decription as adolescent, female, male and immigrant. The analysis highlights that the gender belonging, as the ethnic and cultural belonging, doesn’t drive behaviours, attitudes, expectations totally to tradition or totally to “western way”, in the different everyday contexts. There is rather a combination of these ways, choosing the one or the other way in the different contexts according to be in a position in which there are more or less contacts with the society they live in. Differently, the self perception as adolescent and as individual is relatively independent from gender and ethniccultural belonging, over which prevail the idea of “ peer normality”. Above all, it is important to put in evidence that they are experiencing a very high level of complexity and change as adolescent and migrant or migrant’ son. Personal, cultural and social transitions can explain a large part of variability and our difficulty to construct high defined classifications.

Differenzierung von Reviergesängen und mitochondrialem Cytochrom-b in drei ausgewählten Singvogelgattungen (Aves, Passeriformes: Genus Regulus, Genus Seicercus und Parus major)

ZusammenfassungLautäußerungen von Singvögeln (Passeriformes) werden gemeinhin als Träger phylogenetischer Information betrachtet, obwohl direkte Nachweise in vergleichend bioakustischen Studien rar sind. Dieser Thematik widmet sich meine Dissertation am Beispiel dreier Singvogelgruppen: Goldhähnchen (Regulus), Goldbrillenlaubsänger (Seicercus) sowie verwandter Laubsänger (Phylloscopus) und Kohlmeisen (Parus major). Neben der Erhebung bioakustischer Daten wurde für jede Gruppe eine molekulare Phylogenie basierend auf Cytochrom-b-Sequenzen erstellt und für verschiedene akustische Merkmale Homoplasie-indizes berechnet (CI, RI und RC). Die phylogenetisch informativen Gesangsstrukturen innerhalb der Gattungen Regulus und Seicercus/ Phylloscopus sind sämtlich Syntaxmerkmale, zumeist der Gesamtstrophe, seltener von Strophenabschnitten. Bei den Goldhähnchen (Regulus) sind solche Syntaxmerkmale angeboren, Elementmerkmale hingegen sind erlernt und phylogenetisch nicht informativ. Die innerhalb der Kohlmeisen homogene Gesangssyntax ist erst auf höherer taxonomischer Ebene (Gattung Parus) ein informatives Merkmal. Der mittels einer Merkmalsmatrix berechnete akustische Divergenzindex zwischen Taxonpaaren steigt signifikant proportional zur genetischen Distanz. Damit ist erstmalig der Zusammenhang zwischen genetischer und akustischer Differenzierung quantifiziert. Die molekulare Phylogenie erhellt zudem bislang ungeklärte phylogenetische Beziehungen innerhalb aller drei Taxa. Diese werden im Hinblick auf das phylogenetische und das biologische Artkonzept diskutiert. Der Artstatus des Teneriffa-Goldhähnchens (Regulus teneriffae) sowie der bokharensis-Kohlmeisen ist fragwürdig aufgrund ihrer engen Verwandtschaft zu zu einzelnen Subspezies der Wintergoldhähnchen bzw. der Kohlmeisen.

Economie locali, mondi globali. Per un'etnografia del microcredito in Italia

Local worlds, global economies. For an ethnography of microcredit in Italy. The research main purpose is to provide an anthropological analysis of a microcredit project targeting migrant women in Venice, Italy. Microcredit is a globally widespread financial strategy. Muhammad Yunus’ Grameen Bank success in Bangladesh was pivotal in promoting microfinance as one of the most important poverty alleviation strategies in the Development Countries. Post Industrial Countries adopted microcredit to foster “non bankable” categories – notably immigrants, women and young people - financial inclusion. The history of the Venice project is reconstructed starting from the perspectives of its main characters (promoters, social workers, beneficiaries and local stakeholders). Their positioned representations are analyzed in order to understand how different actors reproduced or renegotiated some of the main rhetorics underpinning the hegemonic “microcredit discourse”. Specifically, keywords such as “sustainability”, “empowerment” and “trust” are critically deconstructed to see how they are meant and translated into practice by different actors. Fieldwork data allows some considerations on the Italian way to microfinance.

Differentiation processes in treecreepers (Aves: Certhia): phylogeny, vocalisations, morphometrics

Evolutionary processes within the bird genus Certhia (treecreepers) are investigated and taxonomic uncertainties clarified. The original seven species of the genus have Holarctic distribution, are uniform morphologically and hence difficult to distinguish. I employed four methodological approaches. 1. Molecular phylogeny using the mitochondrial cytochrome-b gene largely established relationships and revealed two cryptic species. 2. Call and song recordings from all species and many subspecies were evaluated sonagraphically. The nine phylospecies outlined in Part 1 were clearly delimited from one another by time and frequency parameters. They comprise a monophyletic group of "motif singers" and a purely southeast Asian group of "trill singers". Song-character differences were generally consistent with molecular phylogeny (strong phylogenetic signals). 3. Central European Certhia familiaris in the field responded territorially to playback of verses of allopatric "motif singer" taxa, but usually more weakly than to their own subsequently presented songs. No song characters were unambiguously recognised as species-specific. 4. Standard body dimensions of nearly 2000 museum specimens characterise species and subspecies biometrically and reveal geographic trends. Lengths of bill and hind claw proved important parameters to explain the treecreeper lifestyle (climbing and feeding on tree trunks). In the Himalayas (highest species density) tail dimensions are also significant.

Infanzie migranti. La narrativa per ragazzi nelle opere di scrittrici indiane residenti nel Regno Unito e in Canada

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.

Processi e impatti della migrazione. L'esperienza di chi resta in tre famiglie peruviane

Questo studio propone un’esplorazione dei nessi tra fenomeno migratorio, dinamiche transnazionali e quadri familiari, in un contesto specificato che è quello peruviano. Dal confronto critico con i paradigmi disciplinari in uso negli ambiti dell’antropologia delle migrazioni, degli studi sul transnazionalismo e sulle famiglie transnazionali, e dell’etnografia multi-situata, si è tentata una lettura teorica e metodologica che renda conto del contesto socio-familiare di partenza non come parte periferica di una completa visione del migrante, ma quale oggetto specifico della ricerca. L’obbiettivo è verificare, a livello locale, quale siano gli impatti della migrazione esterna di uno o più membri sulle strutture e sulle dinamiche, sui codici e sui ruoli del nucleo parentale originario. E individuare, sul piano transnazionale, quali reti, quali rituali o pratiche di connessione funzionino tra coloro che vanno e coloro che restano, quali discorsi e quali culture migratorie si sviluppino e si condividano. La ricerca si è svolta in Perù tra il 2009 ed il 2011. Il campo dell’indagine si è diviso tra due località nell’area della Costa del Perù. Lima, la capitale, e Chiclín, un villaggio rurale nella regione settentrionale de La Libertad. Attraverso le tecniche d’inchiesta della pratica etnografica, una permanenza prolungata sul terreno e l’osservazione partecipante, si è lavorato con i membri adulti di ambo i sessi di tre gruppi parentali distribuiti tra i due luoghi menzionati, selezionati in partenza sulla base dei contatti forniti da alcuni dei loro familiari emigrati in Italia tra il 1990 ed il 2000. Centrare l’analisi sulle figure per certi aspetti marginali dell’esperienza della migrazione normalmente considerata, è servito da un lato a rovesciare parzialmente la prospettiva transnazionale aggiustandola proprio rispetto a quegli attori sociali; dall’altro e ad un tempo, ha permesso di fare luce su dinamiche migratorie più generali, di ricostruirle e di ri-teorizzarle.
