Italia: La chiusura della Casa dell’Emigrante come spunto riflessione sui rientri degli emigrati italiani

In the literature on migration, as well as in social policies regarding this phenomenon, the situation of returning emigrants receives scant attention. This essay establishes an intricate connection between attitudes and policies that prevail in a country regarding emigration and those concerning immigration. The case of Italy provides a prime example for this as it once was a classical country of emigration, only to turn, in recent decades, into a country that appears highly attractive (and relatively accessible) to immigrants. The essay traces the pervasive ambiguity that characterizes this country’s attitudes towards emigration from the beginning of mass emigration shortly after the unification of Italy in 1868 to the emigration policies of the fascist regime of Mussolini and the post-World War II waves of emigration right through to the corresponding ambiguity concerning the status of immigrants in contemporary society, including the indifferent treatment of returning Italian emigrants who constitute a considerable numerical phenomenon. These reflections take their origin from the impending closure of a reception centre in Lazio, the Casa dell’Emigrante near Sant’Elia Fiumerapido, Province of Frosinone, ostensibly for financial reasons. This centre had been the only one of its kind in the whole of Italy dealing officially with the needs of repatriated Italians. It had assisted returning emigrants both with practical matters, such as negotiating the labyrinth of Italian bureaucracy , and with psychological implications of a return, which are often considerable given the time lag of experiences with current social realities and the frequently unrealistic expectations associated with the return. Questions of identity become highly acute in those circumstances. The threatened closure of the centre illustrates the unwillingness of the state to face up to the factual prevalence of migratory experiences in the country as a whole and as a core element of national history, experiences of migration in both directions. The statistics speak for themselves: of the 4.660.427 persons who left Italy between 1880 and 1950, 2.322.451 have returned, almost exactly 50%. To those have to be added 3.628.430 returnees of the 5.109.860 emigrants who left Italy between the end of World War II and 1976 for Europe alone. Attitudes towards people leaving changed ostensibly over time. In the first two decades after Unification parliament on the one hand wanted to show some concern over the fate of its citizens, not wanting to abandon those newly created citizens entirely to their own destiny, while on the other portraying their decisions to emigrate as expressions of individual liberty and responsibility and not necessitated by want and poverty. Emigrants had to prove, paradoxically that they had the requisite means to emigrate when in fact poverty was largely driving them to emigrate. To admit that publicly would have amounted to admission of economic and political failure made evident through emigration. In contrast to that Mussolini’s emigration policies not only enforced large population movements within the territory of Italy to balance unemployment between regions and particularly between North and South, but also declared it citizen’s duty to be ready to move also to the colonies, thereby ‘turning emigration as a sign of social crisis into a sign of national strength and the success of the country’s political agenda’ (Gaspari 2001, p. 34). The duplicity continued even after World War II when secret deals were done with the USA to allow a continuous flow of Italian immigrants and EU membership obviously further facilitated the departure of unemployed, impoverished Italians. With the growing prosperity of Italy the reversal of the direction of migration became more obvious. On the basis of empirical research conducted by one of the author on returning emigrants four types of motives for returning can be distinguished: 1. Return as a result of failure – particularly the emigrants who left during the 1950-1970 period usually had no linguistic preparation, and in any case the gap between the spoken and the written language is enormous with the latter often being insurmountable. This gives rise to nostalgic sentiments which motivates a return into an environment where language is familiar 2. Return as a means of preserving an identity – the life of emigrants often takes place within ghetto-like conditions where familiarity is being reproduced but under restricted conditions and hence not entirely authentic. The necessity for saving money permits only a partial entry into the host society and at the same time any accumulating savings add to the desire to return home where life can be lived fully again – or so it seems. 3. Return of investment – the impossibility to become fully part of another society often motivates migrants to accumulate not so much material wealth but new experiences and competences which they then aim to reinvest in their home country. 4. Return to retire – for many emigrants returning home becomes acute once they leave a productive occupation and feelings of estrangement build up, in conjunction with the efforts of having invested in building a house back home. All those motives are associated with a variety of difficulties on the actual return home because, above all, time in relation to the country of origin has been suspended for the emigrant and the encounter with the reality of that country reveals constant discrepancies and requires constant readjustment. This is where the need for assistance to returning emigrants arises. The fact that such an important centre of assistance has been closed is further confirmation of the still prevailing politics of ambiguity which nominally demand integration from nationals and non-nationals alike but deny the means of achieving this. Citizenship is not a natural result of nationality but requires the means for active participation in society. Furthermore, the experiences of returning immigrants provide important cues for the double ambivalence in which immigrants to Italy live between the demands made on them to integrate, the simultaneous threats of repatriation and the alienation from the immigrants’ home country which grows inexorably during the absence. The state can only regain its credibility by putting an end to this ambiguity and provide to returning emigrants, and immigrants alike, the means of reconstructing strong communal identities.

Models for intensive care training. A European perspective.

The diversity of European culture is reflected in its healthcare training programs. In intensive care medicine (ICM), the differences in national training programs were so marked that it was unlikely that they could produce specialists of equivalent skills. The Competency-Based Training in Intensive Care Medicine in Europe (CoBaTrICE) program was established in 2003 as a Europe-based worldwide collaboration of national training organizations to create core competencies for ICM using consensus methodologies to establish common ground. The group's professional and research ethos created a social identity that facilitated change. The program was easily adaptable to different training structures and incorporated the voice of patients and relatives. The CoBaTrICE program has now been adopted by 15 European countries, with another 12 countries planning to adopt the training program, and is currently available in nine languages, including English. ICM is now recognized as a primary specialty in Spain, Switzerland, and the UK. There are still wide variations in structures and processes of training in ICM across Europe, although there has been agreement on a set of common program standards. The combination of a common "product specification" for an intensivist, combined with persisting variation in the educational context in which competencies are delivered, provides a rich source of research inquiry. Pedagogic research in ICM could usefully focus on the interplay between educational interventions, healthcare systems and delivery, and patient outcomes, such as including whether competency-based program are associated with lower error rates, whether communication skills training is associated with greater patient and family satisfaction, how multisource feedback might best be used to improve reflective learning and teamworking, or whether increasing the proportion of specialists trained in acute care in the hospital at weekends results in better patient outcomes.

The European Registry for Patients with Mechanical Circulatory Support (EUROMACS): first annual report

The European Registry for Patients with Mechanical Circulatory Support (EUROMACS) was founded on 10 December 2009 with the initiative of Roland Hetzer (Deutsches Herzzentrum Berlin, Berlin, Germany) and Jan Gummert (Herz- und Diabeteszentrum Nordrhein-Westfalen, Bad Oeynhausen, Germany) with 15 other founding international members. It aims to promote scientific research to improve care of end-stage heart failure patients with ventricular assist device or a total artificial heart as long-term mechanical circulatory support. Likewise, the organization aims to provide and maintain a registry of device implantation data and long-term follow-up of patients with mechanical circulatory support. Hence, EUROMACS affiliated itself with Dendrite Clinical Systems Ltd to offer its members a software tool that allows input and analysis of patient clinical data on a daily basis. EUROMACS facilitates further scientific studies by offering research groups access to any available data wherein patients and centres are anonymized. Furthermore, EUROMACS aims to stimulate cooperation with clinical and research institutions and with peer associations involved to further its aims. EUROMACS is the only European-based Registry for Patients with Mechanical Circulatory Support with rapid increase in institutional and individual membership. Because of the expeditious data input, the European Association for Cardiothoracic Surgeons saw the need to optimize the data availability and the significance of the registry to improve care of patients with mechanical circulatory support and its potential contribution to scientific intents; hence, the beginning of their alliance in 2012. This first annual report is designed to provide an overview of EUROMACS' structure, its activities, a first data collection and an insight to its scientific contributions.

Biodiversity and Ecosystem Function in the Gulf of Maine: Pattern and Role of Zooplankton and Pelagic Nekton

This paper forms part of a broader overview of biodiversity of marine life in the Gulf of Maine area (GoMA), facilitated by the GoMA Census of Marine Life program. It synthesizes current data on species diversity of zooplankton and pelagic nekton, including compilation of observed species and descriptions of seasonal, regional and cross-shelf diversity patterns. Zooplankton diversity in the GoMA is characterized by spatial differences in community composition among the neritic environment, the coastal shelf, and deep offshore waters. Copepod diversity increased with depth on the Scotian Shelf. On the coastal shelf of the western Gulf of Maine, the number of higher-level taxonomic groups declined with distance from shore, reflecting more nearshore meroplankton. Copepod diversity increased in late summer, and interdecadal diversity shifts were observed, including a period of higher diversity in the 1990s. Changes in species diversity were greatest on interannual scales, intermediate on seasonal scales, and smallest across regions, in contrast to abundance patterns, suggesting that zooplankton diversity may be a more sensitive indicator of ecosystem response to interannual climate variation than zooplankton abundance. Local factors such as bathymetry, proximity of the coast, and advection probably drive zooplankton and pelagic nekton diversity patterns in the GoMA, while ocean-basin-scale diversity patterns probably contribute to the increase in diversity at the Scotian Shelf break, a zone of mixing between the cold-temperate community of the shelf and the warm-water community offshore. Pressing research needs include establishment of a comprehensive system for observing change in zooplankton and pelagic nekton diversity, enhanced observations of "underknown'' but important functional components of the ecosystem, population and metapopulation studies, and development of analytical modeling tools to enhance understanding of diversity patterns and drivers. Ultimately, sustained observations and modeling analysis of biodiversity must be effectively communicated to managers and incorporated into ecosystem approaches for management of GoMA living marine resources.

Molecular and genetic analyses of Fgf signaling during cardiac outflow tract development

Epithelial-mesenchymal tissue interactions regulate the development of derivatives of the caudal pharyngeal arches (PAs) to govern the ultimate morphogenesis of the aortic arch and outflow tract (OFT) of the heart. Disruption of these signaling pathways is thought to contribute to the pathology of a significant proportion of congenital cardiovascular defects in humans. In this study, I tested whether Fibroblast Growth Factor 15 (Fgf15), a secreted signaling molecule expressed within the PAs, is an extracellular mediator of tissue interactions during PA and OFT development. Analyses of Fgf15−/− mouse embryonic hearts revealed abnormalities primarily localized to the OFT, correlating with aberrant cardiac neural crest cell behavior. The T-box-containing transcription factor Tbx1 has been implicated in the cardiovascular defects associated with the human 22q11 Deletion Syndromes, and regulates the expression of other Fgf family members within the mouse PAs. However, expression and genetic interaction studies incorporating mice deficient for Tbx1, its upstream regulator, Sonic Hedgehog (Shh), or its putative downstream effector, Fgf8, indicated that Fgf15 functions during OFT development in a manner independent of these factors. Rather, analyses of compound mutant mice indicated that Fgf15 and Fgf9, an additional Fgf family member expressed within the PAs, genetically interact, providing insight into the factors acting in conjunction with Fgf15 during OFT development. Finally, in an effort to further characterize this Fgf15-mediated developmental pathway, promoter deletion analyses were employed to isolate a 415bp sequence 7.1Kb 5′ to the Fgf15 transcription start site both necessary and sufficient to drive reporter gene expression within the epithelium of the PAs. Sequence comparisons among multiple mammalian species facilitated the identification of evolutionarily conserved potential trans-acting factor binding sites within this fragment. Subsequent studies will investigate the molecular pathway(s) through which Fgf15 functions via identification of factors that bind to this element to govern Fgf15 gene expression. Furthermore, targeted deletion of this element will establish the developmental requirement for pharyngeal epithelium-derived Fgf15 signaling function. Taken as a whole, these data demonstrate that Fgf15 is a component of a novel, Tbx1-independent molecular pathway, functioning within the PAs in a manner cooperative with Fgf9, required for proper development of the cardiac OFT. ^

Integrated pest management in multi-story public housing for the elderly in Houston, Texas

Integrated pest management is a viable alternative to traditional pest control methods. A paired sample design was utilized to measure the effect of IPM education on the number of cockroaches in a 200 unit, seven story public housing building for the elderly in Houston, TX. Glue traps were placed in 71 randomly selected apartments (5traps/unit) and left in place for two nights. Baseline cockroach counts were shared with the property manager, maintenance/janitorial staff, service coordinator, pest control professional and tenant representatives at the end of a one day “Integrated Pest Management in Multi-Family Housing” training course.^ There was a significant decrease in the average number of cockroaches after IPM education and implementation of IPM principles (P < 0.0003). Positive changes in behavior by members of the IPM team and changes in the housing authority operational plan were also found. Paired t-tests comparing the difference between mean cockroach counts at baseline and follow-up by location within the apartment all demonstrated a significant decrease in the number of cockroaches.^ Results supported the premise that IPM education and the implementation of IPM principles are effective measures to change pest control behaviors and control cockroaches. Cockroach infestations in multi-story housing are not solely determined by the actions of individual tenants. The actions of other residents, property managers and pest control professionals are also important factors in pest control.^ Findings support the implementation of IPM education and the adoption of IPM practices by public housing authorities. This study adds to existing evidence that clear communication of policies, a team approach and a commitment to ongoing inspection and monitoring of pests combined with corrective action to eliminate food, water and harborage and the judicial use of low risk pesticides have the potential to improve the living conditions of elderly residents living in public housing.^

Prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization among dental professionals

Background. MRSA (methicillin-resistant Staphylococcus aureus) is a multi-drug resistant bacterium that is quite prevalent in social environments where close person-to-person contact and crowding are an issue. In dental settings, the likelihood of transmission of MRSA may be higher than among other healthcare practitioners because of the close proximity between a patient's nose (where MRSA colonizes) and the field of procedure (the mouth) to the dental professional. Objective. To estimate the prevalence of MRSA nasal colonization among dental professionals (dentists and dental hygienists) in the Greater Houston Metropolitan Area, Texas, and analyze its associations with demographic, professional and personal protective equipment-related variables. Methods. 800 dental professionals (400 dentists and 400 dental hygienists) were randomly selected in the Greater Houston Metropolitan Area. Multiple waves of nasal swab kits and a self-administered questionnaire were mailed to increase the response rate of the study population. The swabs were cultured on chromagenic agar growth medium and bacterial growth results were evaluated after 18 hours. Positively selected bacterial colonies were confirmed as MRSA by further culturing these isolated bacteria on blood agar plates. Associations between positive nasal swabs and self-reported professional practice patterns, personal protective equipment use and demographics were analyzed using multiple logistic regression. Main Results. Completed questionnaires and nasal swabs were received from 496 study participants (68%). Fourteen cultures were positive for MRSA (4.2% among dentists and 1.6% among dental hygienists, p=0.07). After adjusting for gender, dental hygienists had a significantly lower prevalence of nasal colonization of MRSA as compared to dentists (OR: 0.20, 95% CI: 0.05–0.75). No other significant associations or interactions were found. Conclusion. The prevalence of nasal colonization with MRSA among dentists is similar to that reported for health care workers in general, whereas prevalence among dental hygienists is only slightly above that of the general population (1%). Differences in practice patterns and use of personal protective equipment did not explain this difference in this study, and was possibly due either to residual confounding or unexplored risk factors. Increased prevalence of MRSA among dentists warrants further investigation as to the reason for the increased rate and to allow implementation of measures to avoid transmission and progression to disease. ^

Translating knowledge into action: Information needs of decision-makers in healthcare

Purpose: The purpose of this study was to assess the healthcare information needs of decision-makers in a local US healthcare setting in efforts to promote the translation of knowledge into action. The focus was on the perceptions and preferences of decision-makers regarding usable information in making decisions as to identify strategies to maximize the contribution of healthcare findings to policy and practice. Methods: This study utilized a qualitative data collection and analysis strategy. Data was collected via open-ended key-informant interviews from a sample of 37 public and private-sector healthcare decision-makers in the Houston/Harris County safety net. The sample was comprised of high-level decision-makers, including legislators, executive managers, service providers, and healthcare funders. Decision-makers were asked to identify the types of information, the level of collaboration with outside agencies, useful attributes of information, and the sources, formats/styles, and modes of information preferred in making important decisions and the basis for their preferences. Results: Decision-makers report acquiring information, categorizing information as usable knowledge, and selecting information for use based on the application of four cross-cutting thought processes or cognitive frameworks. In order of apparent preference, these are time orientation, followed by information seeking directionality, selection of validation processes, and centrality of credibility/reliability. In applying the frameworks, decision-makers are influenced by numerous factors associated with their perceptions of the utility of information and the importance of collaboration with outside agencies in making decisions as well as professional and organizational characteristics. Conclusion: An approach based on the elucidated cognitive framework may be valuable in identifying the reported contextual determinants of information use by decision-makers in US healthcare settings. Such an approach can facilitate active producer/user collaborations and promote the production of mutually valued, comprehensible, and usable findings leading to sustainable knowledge translation efforts long-term.^

El objetivo fue analizar el proceso de cambio tecnológico, teniendo en cuenta la incidencia de la innovación y en particular del diseño; analizar las políticas públicas provinciales dirigidas hacia este subsector. Metodológicamente se combinaron los paradigmas cuantitativo y cualitativo. Se pudo caracterizar el subsector y los empresarios de las empresas. Se espera que con los resultados puedan verse beneficiados organismos públicos y privados e instituciones académicas (UNCuyo), especialmente los dedicados a la vinculación con el medio productivo.

Comunicación bucosinusal : diagnóstico con tomografía cone beam CBCT

Existe una estrecha relación entre 10s ápices de 10s molares superiores y el seno maxilar. Cualquier maniobra quirúrgica o lesión en estas piezas dentales pueden provocar una comunicación entre el seno maxilar y la cavidad bucal. Si bien el diagnóstico de la comunicación bucosinusal es fundamentalmente clínico, en muchas ocasiones 10s signos clínicos no son evidentes ni concluyentes. El estudio con Tomografía Cone Beam CBCT en tres dimensiones otorga una visualización en tres planos del espacio de las estructuras óseas y dentoalveolares permitiendo realizar un diagnóstico preciso de la magnitud y correcta localización de las comunicaciones bucosinusales, facilitando la planificación quirúrgica al profesional y evitando complicaciones al paciente.

Efecto de la interacción genotipo-ambiente sobre la expresión del contenido de allicina y ácido pirúvico en ajo (Allium sativum L.)

La expresión de la intensidad del flavor en los bulbos de ajo (Allium sativum L.), depende tanto de factores genéticos como ambientales. Las características organolépticas se manifiestan por la presencia de compuestos organoazufrados, específicamente tiosulfinatos, siendo el representante mayoritario la allicina (diallil tiosulfinato). El ácido pirúvico constituye un producto secundario de la reacción enzimática generadora del flavor, por lo que su medición se asocia a la intensidad de pungencia en ajo. El objetivo del presente trabajo fue estudiar si la variabilidad en el contenido de allicina y pirúvico está más asociada a las características genéticas o a la influencia de las regiones de cultivo. Se seleccionaron cuatro cultivares (Castaño INTA, Sureño INTA, Lican INTA y Unión) pertenecientes al banco de germoplasma del Instituto Nacional de Tecnología Agropecuaria (INTA) La Consulta, Mendoza, Argentina, cultivados en diferentes zonas geográficas: La Consulta (Dpto. San Carlos, Mendoza), Esquel (Chubut) y Ushuaia (Tierra del Fuego). Se cuantificó la allicina mediante Cromatografía Líquida de Alta Resolución (HPLC) y pungencia mediante espectrofotometría. A partir del análisis estadístico de los valores obtenidos se puede inferir que existen diferencias significativas en el contenido de allicina y pirúvico entre distintas cultivares de una misma zona y en el contenido de allicina y pirúvico para la misma cultivar en distintas zonas.

Las prácticas de la enseñanza en la Educación Superior : Reflexiones pedagógico-didácticas sobre los usos de las tecnologías informáticas en las aulas

El presente trabajo da cuenta de una investigación llevada a cabo entre mediados y fines de los años `90 como parte de la acreditación académica del grado de Licenciatura en Ciencias de la Educación. La misma aborda como tema de estudio el campo de la Educación Superior y las Tecnologías Informáticas, particularmente el uso pedagógico-didáctico que se hace de dichas tecnologías a partir de su introducción en las prácticas de enseñanza. Metodológicamente se trabajó en dos etapas con de estilos de indagación diferenciados, pero a la vez imbricados. La primera consistió en recoger la mirada institucional respecto a la introducción de dichas tecnologías. A tales efectos, se seleccionó como población del estudio a miembros responsables de la conducción institucional de algunas de las Unidades Académicas de la Universidad Nacional de La Plata e Institutos Superiores de Formación Docentes -públicos y privados- de la provincia de Bs. As. Mientras que la segunda etapa se configuró a partir de los hallazgos de la anterior dando lugar a la necesidad de profundizar, mediante un estudio de casos, en el análisis de prácticas de enseñanza en las que se produce la inclusión de las tecnologías informáticas. Intentando visualizar en ellas, no sólo, la introducción de un artefacto novedoso sino la presencia de elementos de una cultura de innovación educativa que den cuenta de procesos de reflexión y de cambio en dichas prácticas. Las conclusiones arribadas posibilitaron integrar la dimensión institucional con la dimensión áulica; conocer prácticas de enseñanza que intentan, desde su espacio de trabajo, modificar la estructura de clase tradicional, acercando a los alumnos otras posibilidades de acceso al conocimiento y vislumbrar, en forma incipiente y en función de las posibilidades profesionales y personales de cada profesor, niveles de reflexión de su propia práctica con el propósito de mejorarlas.

El PRT-ERP y la lucha por la libertad de los presos políticos, 1971-1973

Este trabajo aborda la represión política de la militancia revolucionaria por parte del régimen militar y la problemática de los presos políticos en la etapa 1971-1973 en Argentina. Se realiza un análisis de las principales características de la legislación represiva. Centralmente refiere a las diferentes iniciativas desarrolladas por el PRT-ERP en relación con sus militantes presos y en particular a la constitución de una Comisión de familiares de presos políticos, estudiantiles y gremiales para la organización de la solidaridad y defensa de los mismos. Apuntamos a destacar la amplia actividad de defensa y solidaridad con los presos políticos desarrollada por un conjunto de organizaciones como un antecedente importante, pero no reconocido, para la constitución del movimiento de derechos humanos de la Argentina en 1975-1976
