Beyond methodological nationalism: The contribution of Robert E. Park to the history of intercultural communication

The legacy of nineteenth century social theory followed a “nationalist” model of society, assuming that analysis of social realities depends upon national boundaries, taking the nation-state as the primary unit of analysis, and developing the concept of methodological nationalism. This perspective regarded the nation-state as the natural - and even necessary - form of society in modernity. Thus, the constitution of large cities, at the end of the 19th century, through the intense flows of immigrants coming from diverse political and linguistic communities posed an enormous challenge to all social research. One of the most significant studies responding to this set of issues was The Immigrant Press and its Control, by Robert E. Park, one of the most prominent American sociologists of the first half of the 20th century. The Immigrant Press and its Control was part of a larger project entitled Americanization Studies: The Acculturation of Immigrant Group into American Society, funded by the Carnagie Corporation following World War I, taking as its goal to study the so-called “Americanization methods” during the 1920s. This paper revisits that particular work by Park to reveal how his detailed analysis of the role of the immigrant press overcame the limitations of methodological nationalism. By granting importance to language as a tool uniting each community and by showing how the strength of foreign languages expressed itself through the immigrant press, Park demonstrated that the latter produces a more ambivalent phenomenon than simply the assimilation of immigrants. On the one hand, the immigrant press served as a connecting force, driven by the desire to preserve the mother tongue and culture while at the same time awakening national sentiments that had, until then, remained diffuse. Yet, on the other hand, it facilitated the adjustment of immigrants to the American context. As a result, Park’s work contributes to our understanding of a particular liminal moment inherent within many intercultural contexts, the space between emigrant identity (emphasizing the country of origin) and immigrant identity (emphasizing the newly adopted country). His focus on the role played by media in the socialization of immigrant groups presaged later work on this subject by communication scholars. Focusing attention on Park’s research leads to other studies of the immigrant experience from the same period (e.g., Thomas & Znaniecki, The Polish Peasant in Europe and America), and also to insights on multi-presence and interculturality as significant but often overlooked phenomena in the study of immigrant socialization.

Life Cycle Assessment of the Hybrid Vehicle – Toyota Prius

Die Luftverschmutzung, die globale Erwärmung sowie die Verknappung der endlichen Ressourcen sind die größten Bedenken der vergangenen Jahrzehnte. Die Nachfrage nach jeglicher Mobilität steigt rapide. Dementsprechend bemüht ist die Automobilindustrie Lösungen für Mobilität unter dem Aspekt der Nachhaltigkeit und dem Umweltschutz anzubieten. Die Elektrifizierung hat sich hierbei als der beste Weg herausgestellt, um die Umweltprobleme sowie die Abhängigkeit von fossilen Brennstoffen zu lösen. Diese Arbeit soll einen Einblick über die Umweltauswirkungen des Hybridfahrzeuges Toyota Prius geben. Hierbei findet eine Gliederung in vier verschiedene Lebensphasen statt. Im Anschluss bietet die Sachbilanz die Möglichkeit die Umweltauswirkungen mit verschiedenen Antriebsmöglichkeiten und Brennstoffen zu vergleichen. Das Modell hat gezeigt, dass der Toyota Prius während der Nutzung einen hohen Einfluss auf das Treibhauspotenzial aufweist. Durch die Nutzung anderer Brennstoffe, wie beispielsweise Ethanol oder Methanol lassen sich die Auswirkungen am Treibhauspotenzial sowie der Verbrauch an abiotischen Ressourcen reduzieren. Vergleicht man die Elektromobilität mit der konventionellen, so ist festzustellen, dass diese Art der Mobilität die derzeit beste Möglichkeit zur Reduzierung der Umweltbelastungen bietet. Die Auswirkungen der Elektromobilität sind im hohen Maße abhängig von der Art des verwendeten Strommixes.

Why and How Was Regionalization of Perinatal Care Accomplished in Portugal?

Portuguese health care system was created in 1979. It is universal and for free. Expenses are supported by the State through taxes. The modern perinatal care system started by the end of 1970. The first neonatal intensive care units were created in 1980, the Portuguese Neonatal Society in 1985 and the National Neonatal Transport System in 1987. Until the seventies of twentieth century and even during eighties there were more than 200 hospitals with deliveries, a great part without obstetrician or paediatrician, a great percentage of pregnancies had no prenatal care, there were few neonatal intensive care units and perinatal mortality rate was one of the highest in the European countries. In 1987 an Experts Committee was nominated by the Health Ministry aiming to collect and analyse data on perinatal care and to suggest improvements. The Report resulting from this work is the main document on which is based the reform. The reform was a 9 years program in 3 years stages aiming to close hospitals with less than 1500 deliveries/year, to reclassify hospitals, to create Coordinating Units between health centres and hospitals, to equip neonatal intensive and intermediate care units, to define needs of obstetricians, paediatricians and nurses for each centre and to promote specialised training in neonatology for paediatricians and nurses. Levels of perinatal care were defined as well as localization of each level of hospital according to the number of deliveries in one geographic area, geographic difficulties and existing routes and connections. Steps for opening and closure of different levels of hospitals were very well programmed. The organization, capacities, number of obstetricians, neonatologists and nurses as well as equipment for each level of care was defined. Rules for pregnant women and newborns transfer from level II to level III hospitals were also well described. A specific training is neonatology was created starting in 1990. This organization resulted in an impressive decrease in mortality rates at all levels and still it is the policy we have today.

Criminosos popularizados na narrativa de divulgação (De 1838 aos Alvores da República)

O presente estudo incide sobre obras impressas que tomaram como motivo central as «façanhas» de criminosos com referência histórica celebrizados em Portugal na segunda metade do século XIX e inícios de XX e mostra que, enquanto narrativas elaboradas para o grande público, os textos foram não só um reflexo da popularidade prévia dos famigerados transgressores, como também um fator incontornável da sua «lendarização» ao longo de décadas. São as seguintes as figuras dos infratores que protagonizaram as ficções em apreço: José Joaquim de Sousa Reis, ou «o Remexido» (1797-1838), Diogo Alves, ou «o Pancada» (1810-1841), Francisco de Matos Lobo (1814-1842), José Teixeira da Silva, ou «o José do Telhado» (1816-1875), João Victor da Silva Brandão, ou «o João Brandão de Midões» (1825-1880), e Vicente Urbino de Freitas (1859-1913). A tese agora apresentada aborda um corpus textual de características singulares, nunca antes coligido nem estudado. Comprova que os textos sobre as figuras criminosas tiveram uma função iminentemente noticiosa, pedagógico-edificante e política, apropriando-se de relatos orais, adotando procedimentos de atestação da veracidade (transcrição de documentos na primeira pessoa, referenciação cronológica, espacial, geográfica dos eventos, alusão às fontes) e incorporando diversas fontes do conhecimento dos crimes, quer de origem popular (geralmente designadas de «musa popular», «tradição»), quer de caráter erudito e teórico-científico («estudo», «estudo social»). Assim, foram analisadas as condições históricas excecionais nas quais as ficções emergiram: as características específicas do seu universo editorial, a apropriação a um público amplo (o formato de coleção, uso de sinopses e de outros elementos gráficos), as regularidades discursivas das obras (ocorrência de determinados dispositivos de organização textual), os procedimentos narrativos (recurso abundante a paratextos com intuito explicativo e aproximação a modalidades ficcionais conhecidas do público da época) e, ainda, as configurações imagéticas inspiradas nos discursos oficiais (influência de ciências e doutrinas epocais emergentes, como a criminologia, a antropologia criminal, a frenologia, a psiquiatria, a sociologia). Em suma, estas edições produzidas em diversos contextos e por um elenco autoral heterogéneo não só viveram da relação com as edições predecessoras, ao longo de gerações, como recriaram e ampliaram as «façanhas» dos transgressores em função de diversos propósitos e fontes: ampla divulgação dos casos criminais, condenação pública dos infratores, análise médico-científica dos sujeitos culpados, especulação política, pressão sobre o foro judiciário, edificação moral do público leitor. Trata-se, sem dúvida, de produções únicas, que erigiram a comemoração dos facínoras e sucessivamente reinscreveram as suas histórias reais na problemática do homem criminal e na consciência ética do seu tempo.

Sensitivity of the Amazon biome to high resolution climate change projections

ABSTRACT: Despite the reduction in deforestation rate in recent years, the impact of global warming by itself can cause changes in vegetation cover. The objective of this work was to investigate the possible changes on the major Brazilian biome, the Amazon Rainforest, under different climate change scenarios. The dynamic vegetation models may simulate changes in vegetation distribution and the biogeochemical processes due to climate change. Initially, the Inland dynamic vegetation model was forced with initial and boundary conditions provided by CFSR and the Eta regional climate model driven by the historical simulation of HadGEM2-ES. These simulations were validated using the Santarém tower data. In the second part, we assess the impact of a future climate change on the Amazon biome by applying the Inland model forced with regional climate change projections. The projections show that some areas of rainforest in the Amazon region are replaced by deciduous forest type and grassland in RCP4.5 scenario and only by grassland in RCP8.5 scenario at the end of this century. The model indicates a reduction of approximately 9% in the area of tropical forest in RCP4.5 scenario and a further reduction in the RCP8.5 scenario of about 50% in the eastern region of Amazon. Although the increase of CO2 atmospheric concentration may favour the growth of trees, the projections of Eta-HadGEM2-ES show increase of temperature and reduction of rainfall in the Amazon region, which caused the forest degradation in these simulations.

El Derecho norteamericano como impulsor de la responsabilidad civil del fabricante por productos defectuosos

Investigación elaborada a partir de una estancia en la Columbia Law School of New York, Estados Unidos, entre los meses de septiembre y noviembre del 2006. El Derecho comunitario europeo y español regulan la reparación de los daños causados por el uso o la proximidad de un producto defectuoso mediante gracias al impulso ideológico ejercido por la jurisprudencia norteamericana. El principio de responsabilidad objetiva rector de la directiva europea es fruto de un transfondo operado en los Estados Unidos en los años sesenta, coincidiendo con la revolución tecnològica y el inicio de la producción y del consumo masivos. Tales fenómenos suscitaron la búsqueda de mecanismos jurídicos aptos para canalizar la reparación de los daños inherentes a las actividades industriales tecnológicamente avanzadas. Su principal efecto fue la preocupación por una más justa distribución social de los llamados “costes del progreso”, preocupación que, jurídicamente, desembocó en la solución de la responsabilidad aun sin culpa del fabricante por los daños derivados de su producción industrial. El mérito de tal solución corresponde a determinados teóricos norteamericanos de la responsabilidad empresarial, quienes, inspirándose en ideas formuladas a inicios del siglo XX por los especialistas en Derecho laboral, concluyeron que es la empresa productora quien está en mejor situación de soportar el coste del accidente industrial: al imponerse al fabricante una responsabildad desvinculada de su eventual culpa en la causación del accidente, repercutirá en el precio de sus productos el coste del seguro de responsabilidad civil que se verá abocado a contratar para hacer frente a su responsabilidad objetiva o por riesgo, de manera que el coste de los accidentes acabará siendo soportado por el público consumidor al pagar el sobreprecio de los productos que adquiere. Las repercusiones de tal construcción han sido tanto normativas como judiciales.

21st century climate change threatens mountain flora unequally across Europe

Continental-scale assessments of 21st century global impacts of climate change on biodiversity have forecasted range contractions for many species. These coarse resolution studies are, however, of limited relevance for projecting risks to biodiversity in mountain systems, where pronounced microclimatic variation could allow species to persist locally, and are ill-suited for assessment of species-specific threat in particular regions. Here, we assess the impacts of climate change on 2632 plant species across all major European mountain ranges, using high-resolution (ca. 100 m) species samples and data expressing four future climate scenarios. Projected habitat loss is greater for species distributed at higher elevations; depending on the climate scenario, we find 36-55% of alpine species, 31-51% of subalpine species and 19-46% of montane species lose more than 80% of their suitable habitat by 2070-2100. While our high-resolution analyses consistently indicate marked levels of threat to cold-adapted mountain florae across Europe, they also reveal unequal distribution of this threat across the various mountain ranges. Impacts on florae from regions projected to undergo increased warming accompanied by decreased precipitation, such as the Pyrenees and the Eastern Austrian Alps, will likely be greater than on florae in regions where the increase in temperature is less pronounced and rainfall increases concomitantly, such as in the Norwegian Scandes and the Scottish Highlands. This suggests that change in precipitation, not only warming, plays an important role in determining the potential impacts of climate change on vegetation.

Ecoepidemiological aspects of american cutaneous leishmaniasis in the state of São Paulo, Brazil

The aim of this study is to review some of the ecoepidemiological aspects of american cutaneous leishmaniasis (ACL) in the state of São Paulo, Brazil. During the first half of this century ACL occured in São Paulo, predominantly on the bank of the Tietê river, where there were railroad constructions and there was inevitable contact between and forested areas. Man's activities resulted in a drastic reduction of the forested regions of the state and molded the present landscape found in São Paulo, which brought a gradual change in the epidemiology of ACL during this century. Currently ACL can be considered as an endemic disease. Nowadays, ACL is found in different regions of São Paulo state, and is no longer limited to the bank of the Tietê river. The disease occurs in all age groups and sexes. Lack of knowledge about wild reservoir hosts of Leishmania (V.) braziliensis has simulated speculation about the possible role played by domestic animals (dogs and equines). Man's activities also favoured Lutzomyia intermedia a sandfly species which can clearly thrive in changed environments L. (V.) braziliensis continues to be transmitted, even after decades of forest destruction in São Paulo.

On problems of calculating energy expenditure and substrate utilization from respiratory exchange data.

Indirect calorimetry based on respiratory exchange measurement has been successfully used from the beginning of the century to obtain an estimate of heat production (energy expenditure) in human subjects and animals. The errors inherent to this classical technique can stem from various sources: 1) model of calculation and assumptions, 2) calorimetric factors used, 3) technical factors and 4) human factors. The physiological and biochemical factors influencing the interpretation of calorimetric data include a change in the size of the bicarbonate and urea pools and the accumulation or loss (via breath, urine or sweat) of intermediary metabolites (gluconeogenesis, ketogenesis). More recently, respiratory gas exchange data have been used to estimate substrate utilization rates in various physiological and metabolic situations (fasting, post-prandial state, etc.). It should be recalled that indirect calorimetry provides an index of overall substrate disappearance rates. This is incorrectly assumed to be equivalent to substrate "oxidation" rates. Unfortunately, there is no adequate golden standard to validate whole body substrate "oxidation" rates, and this contrasts to the "validation" of heat production by indirect calorimetry, through use of direct calorimetry under strict thermal equilibrium conditions. Tracer techniques using stable (or radioactive) isotopes, represent an independent way of assessing substrate utilization rates. When carbohydrate metabolism is measured with both techniques, indirect calorimetry generally provides consistent glucose "oxidation" rates as compared to isotopic tracers, but only when certain metabolic processes (such as gluconeogenesis and lipogenesis) are minimal or / and when the respiratory quotients are not at the extreme of the physiological range. However, it is believed that the tracer techniques underestimate true glucose "oxidation" rates due to the failure to account for glycogenolysis in the tissue storing glucose, since this escapes the systemic circulation. A major advantage of isotopic techniques is that they are able to estimate (given certain assumptions) various metabolic processes (such as gluconeogenesis) in a noninvasive way. Furthermore when, in addition to the 3 macronutrients, a fourth substrate is administered (such as ethanol), isotopic quantification of substrate "oxidation" allows one to eliminate the inherent assumptions made by indirect calorimetry. In conclusion, isotopic tracers techniques and indirect calorimetry should be considered as complementary techniques, in particular since the tracer techniques require the measurement of carbon dioxide production obtained by indirect calorimetry. However, it should be kept in mind that the assessment of substrate oxidation by indirect calorimetry may involve large errors in particular over a short period of time. By indirect calorimetry, energy expenditure (heat production) is calculated with substantially less error than substrate oxidation rates.

Macrophage migration inhibitory factor: a regulator of innate immunity.

For more than a quarter of a century, macrophage migration inhibitory factor (MIF) has been a mysterious cytokine. In recent years, MIF has assumed an important role as a pivotal regulator of innate immunity. MIF is an integral component of the host antimicrobial alarm system and stress response that promotes the pro-inflammatory functions of immune cells. A rapidly increasing amount of literature indicates that MIF is implicated in the pathogenesis of sepsis, and inflammatory and autoimmune diseases, suggesting that MIF-directed therapies might offer new treatment opportunities for human diseases in the future.

Can Families Resist Managerial and Financial Revolutions? Swiss Family Firms in the Twentieth Century

The aim of this contribution is to highlight the long-term evolution of family capitalism in Switzerland during the twentieth century. We focus on 22 large companies of the machine, electrotechnical and metallurgy (MEM) sector whose boards of directors and general managers have been identified in five benchmark years across the twentieth century, which allows us to distinguish between family-owned and family-controlled firms. Our results show that family firms prevailed until the 1980s and thus contradict the dominance of 'managerial capitalism'. Although we observe a decline of family capitalism during the last decade of the century, the significant remaining presence of family firms in 2000 allows us to relativise the advent of investor capitalism.

Next-generation sequencing of experimental mouse strains.

Since the turn of the century the complete genome sequence of just one mouse strain, C57BL/6J, has been available. Knowing the sequence of this strain has enabled large-scale forward genetic screens to be performed, the creation of an almost complete set of embryonic stem (ES) cell lines with targeted alleles for protein-coding genes, and the generation of a rich catalog of mouse genomic variation. However, many experiments that use other common laboratory mouse strains have been hindered by a lack of whole-genome sequence data for these strains. The last 5 years has witnessed a revolution in DNA sequencing technologies. Recently, these technologies have been used to expand the repertoire of fully sequenced mouse genomes. In this article we review the main findings of these studies and discuss how the sequence of mouse genomes is helping pave the way from sequence to phenotype. Finally, we discuss the prospects for using de novo assembly techniques to obtain high-quality assembled genome sequences of these laboratory mouse strains, and what advances in sequencing technologies may be required to achieve this goal.

Advances in our understanding of mammalian sex-biased dispersal.

Sex-biased dispersal is an almost ubiquitous feature of mammalian life history, but the evolutionary causes behind these patterns still require much clarification. A quarter of a century since the publication of seminal papers describing general patterns of sex-biased dispersal in both mammals and birds, we review the advances in our theoretical understanding of the evolutionary causes of sex-biased dispersal, and those in statistical genetics that enable us to test hypotheses and measure dispersal in natural populations. We use mammalian examples to illustrate patterns and proximate causes of sex-biased dispersal, because by far the most data are available and because they exhibit an enormous diversity in terms of dispersal strategy, mating and social systems. Recent studies using molecular markers have helped to confirm that sex-biased dispersal is widespread among mammals and varies widely in direction and intensity, but there is a great need to bridge the gap between genetic information, observational data and theory. A review of mammalian data indicates that the relationship between direction of sex-bias and mating system is not a simple one. The role of social systems emerges as a key factor in determining intensity and direction of dispersal bias, but there is still need for a theoretical framework that can account for the complex interactions between inbreeding avoidance, kin competition and cooperation to explain the impressive diversity of patterns.
