Abstract: objective: catalonia and the basque country received substantial immigration quotas from the rest of spain during the twentieth century. this study aimed to analyze inequalities in health by birthplace (the population born in the same region or other autonomous regions) in these two geographical areas. methods: we conducted a cross-sectional study in the non-institutionalized population aged 50 to 79 years, with data from the health surveys of catalonia 2006 (n=5,483) and the basque country 2007 (n=3,424). we used log-binomial models to estimate the prevalence ratios (pr) of poor self-rated health by birthplace, stratified by sex and social class, and successively adjusted for age, social class and educational attainment. results: immigrants from other autonomous regions had poorer self-rated health than the native-born population, both in the basque country (age-adjusted pr in men 1.30, 95% ci 1.11-1.54; women 1.42, 95% ci 1.25-1.62,) and in catalonia (pr in men 1.41, 95% ci 1.26-1.62; pr in women 1.25, 95% ci 1.16-1.35). prs were reduced but remained significant after adjustment for social class and educational attainment and stratification by manual or non-manual social class. conclusions: in both communities there are health inequalities that are detrimental to the immigrant population from the rest of spain, which constitutes approximately half of the population in the studied age cohorts. future studies should explore the persistence of these inequalities in other health indicators and their reproduction in second generations, and identify entry points for preventive policies.
Review Essay: Gespr chsforschung: Zur Praxis von Fokusgruppen Review Essay: Focus Group Practices: Studying Conversation Ensayo: Estudiando la conversación
Gonzalo Bacigalupe
Forum : Qualitative Social Research , 2005,
Abstract: Focus Group Practice besch ftigt sich mit für den Erfolg von Fokusgruppen f rderlichen Interaktionsprozessen und Moderationstechniken. Gestützt auf theoretische und methodologische Ans tze aus der Diskurs- und Konversationsanalyse werden die für Fokusgruppen charakteristischen "Mikropraktiken" untersucht. In sieben Kapiteln werden Empfehlungen für Moderator(inn)en und Forscher(innen) gegeben, die sich für die Methodologie von Fokusgruppen interessieren. Dabei ist das Buch, in dessen Zentrum die Analyse von Gespr chsprozessen steht, nicht als "Rezeptur" für die Gestaltung von Fokusgruppen konzipiert, sondern es handelt sich vielmehr um ein vorsichtiges Herausarbeiten der Choreographie, die für erfolgreiche Gruppeninterviews notwendig ist. Zus tzlich enth lt Focus Group Practice eine Reihe kurzer Beispiele zu Fokusgruppen in der Marktforschung sowie Definitionen zur Konversationsanalyse und von Schlüsselbegriffen der diskursiven Psychologie. Ein – in jedem Kapitel vorhandener – Satz an Grundregeln bezieht sich darauf, was wirkungsvolle Fokusgruppeninteraktionen ausmacht (formaler/informeller Charakter von Interaktion, Partizipation, Meinungen, usw.). Auch werden einige zus tzliche Informationen geboten z.B. zu Transkriptionen in der Konversationsanalyse. URN: urn:nbn:de:0114-fqs050293 Focus Group Practice aims at analyzing the interactional process that supports the success of focus groups. The book makes specific observations of what effective focus group moderation can accomplish. Informed by theoretical and methodological approaches taken from conversation and discourse analysis, this work aims at an analysis of the micro-practices that characterize the focus group process. The seven chapters of the book include recommendations for moderators as well as researchers interested in studying focus group methodology as a subject in itself. The book, an analysis of what goes on in the form of conversational processes, is purposely not a "how to" of focus groups, but rather a careful unveiling of the "choreographic" movements that lead to successful group interviews. It includes a series of brief examples of market-research focus groups and pedagogical definitions of conversation analysis and discursive psychology key concepts. A set of principles related to what creates an effective focus group interaction organizes each chapter (interaction, informality, participation, and opinions). Also included are some conversational analysis artifacts like explanations about how transcription is employed in conversational analysis. URN: urn:nbn:de:0114-fqs050293 Práctic
Review Essay: Eine Einladung zum intuitiven Verstehen in der Lehre und in der Praxis: Ist Intuition neutral? Review Essay: Inviting Intuitive Understandings in Teaching and Professional Practices: Is Intuition Relationally and Culturally Neutral? Ensayo: Invitación a la comprensión intuitiva en la ense anza y en la práctica profesional: Es la intuición neutral?

Abstract: Terry ATKINSON und Guy CLAXTON analysieren das Konstrukt der "Intuition" ausgehend von Forschungs- und Lehrerfahrung an der Universit t Bristol in Gro britannien. In vierzehn Kapiteln wird die meist schwer zu fassende Idee der Intuition und ihr Einfluss auf professionelles Handeln untersucht, wobei viele der Autor(inn)en Intuition eher als eine kognitive psychologische Strategie definieren und weniger als relationalen und kulturellen Austausch. Das letzte Kapitel enth lt eine kritische Zusammenfassung und Bewertung von ERAUT, der nicht der Universit t Bristol angeh rt. Das Buch ist weniger eine integrierte theoretische Zusammenschau, sondern eher ein abschlie ender Bericht, der die universit ren Diskussionen und die Forschung der Autor(inn)en versammelt. Das Resultat ist eine inspirierende Darstellung sich überlappender Konzepte, die die Leser(innen) über die Relevanz von Intuition in p dagogischen und professionellen Handlungsfeldern informiert. Allerdings ist das Buch nicht in erster Linie geeignet für Berufst tige, die konkrete Methoden für die Umsetzung intuitiver Praktiken erlernen wollen, oder für Forscher(innen), die für die Analyse der Intuition in verschiedenen kulturellen und/oder institutionellen Kontexten auf der Suche nach anwendbaren theoretischen Konstrukten sind. URN: urn:nbn:de:0114-fqs0204514 To analyze the construct of intuition, Terry ATKINSON and Guy CLAXTON draw from the research, teaching experiences, and theoretical expertise of faculty at the University of Bristol, UK. The fourteen chapters by the faculty at Bristol explore the often slippery notion of "intuition" and its impact in professional practice, which is generally (and there are exceptions) defined as a cognitive psychological strategy rather than a relational and cultural exchange. The last chapter is a critical summary by ERAUT who assesses the book as an outsider to Bristol. The book reads like a final report of discussions and research by the authors within a university context rather than a cohesive theoretical summary by a sole author. The result is inspiring as a review of overlapping ideas that inform the reader of the relevance of intuition in educational and professional settings within the context of educational reforms during the last decade in several countries. It will not be compelling reading for professionals attempting to learn a set of activities that would aid them in learning how to incorporate "intuitive practices" or for researchers searching for ways of clearly formalizing intuition as a well-defined theoretical construct that can be analyzed in v
Community Violence as Psychosocial Stressor:The Case of Childhood Asthma in Boston  [PDF]
Gonzalo Bacigalupe, Takeo Fujiwara, Sabrina Selk, Meghan Woo
Psychology (PSYCH) , 2010, DOI: 10.4236/psych.2010.11005
Abstract: Childhood asthma is a critical public health problem of urban centers in the United States and other industrialized nations. Population-based and laboratory research studies indicate that psychosocial stress differentially affects asthma expression. Witnessing or experiencing community violence is a psychosocial stressor that results in long-term biological changes that may in turn contribute to asthma morbidity. This is a review of the literature that examines the exposure to violence as a psychosocial stressor that is independently associated with asthma morbidity even after adjustment for income, housing, and other adverse life events. In addition to acting as a physiological trigger for the disease, community violence can also impact health behaviors and exposure to other unknown environmental risk factors. This connection leads the authors to suggest that reducing violence and the amelioration of its impact has implications beyond public health. The City of Boston in Massachusetts serves as the context to contextualize a series of recommendations that may ameliorate and/or prevent asthma incidence and prevalence. The reduction of poverty, unemployment, substandard housing, and high crime/violence rates can have significant health implications for children asthma and a decline on asthma hospitalization.
Some Notes on Modelling the Relationship between the Environment and Institutional Context  [PDF]
Davide Infante, Janna Smirnova
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.21003
Abstract: Being a real concern of any society, environmental quality has received much attention in economic litera-ture. However, the role that the institutional context plays in environmental issues is still an open question. Since the environment and institutional context are closely interrelated through government regulation, the investigation on the relationship between environment-institutions represents a fruitful terrain for economic research. Our aim is to design research notes to study this relationship using theoretical and empirical ap-proaches, by modelling the institutional context and estimating its impact on the environment. Our notes could also shed fresh light on the issue of environmental policies and their implementation in emerging and developing economies.
Entry and Collusion after Market Opening  [PDF]
Federico Boffa, Davide Vannoni
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.23058
Abstract: We analyze a setting typical of industries right after liberalization, or after structural demand and technology changes. An incumbent firm has an exogenous capacity, and a new entrant has to set its capacity level. We find that, in a dynamic context, higher capacity increases the severity of punishment after deviation, thereby favoring the emergence of cartels. The cartel in this case could hurt welfare, not only because of the standard deadweight loss motive, but also because of the cost inefficiency due to high and idle capacity. We conjecture that a competitive arrangement could be both welfare enhancing and profit-maximizing for the incumbent.
Mitigation of Human Exposure to Electromagnetic Fields Using Carbon Foam and Carbon Nanotubes  [PDF]
Davide Micheli, Mario Marchetti
Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.412A118
Abstract:

In recent years there has been increasing concern about the possible consequences on human health from exposure to RF fields produced by wireless telecommunication technologies. In this work the coupling between carbon foam and composite materials made of carbon nanotubes and epoxy-resin allows to build a material able to absorb the electromagnetic field thus reducing its intensity in the environment where the mitigation of electromagnetic field is required. The Frequency range considered is 2 GHz - 3 GHz which is the most common frequency band used in wireless network and microwave oven too. Two different kind of heterogeneous materials are designed, one is a layered radar absorbing material made exclusively of epoxy resin and carbon nanotube in different weight percentage, the others are porous carbon foam where the pores are supposed be filled with carbon nanotubes and epoxy-resin. Both type of materials show interesting absorption properties reaching peak of reflection coefficient between –15 dB and –45 dB for a normally incident plane wave.

Abstract: Changes induced by cerebrovascular damage (CVD) and amigdalo-hippocampal atrophy (AHC) on brain rhythmicity as?revealed?by scalp electroencephalography (EEG) were evaluated in a cohort of subjects with mild cognitive impairment (MCI) in order to detect different EEG patterns due to the vascular or degenerative impairment. All subjects underwent EEG recording and magnetic resonance imaging (MRI). EEGs were recorded at rest. Relative power was separately computed for delta, theta, alpha1, alpha2, and alpha 3 frequency bands. Increased delta power and decreased alpha2 power were associated with the load of cerebrovascular damage (CVD). Moreover, the theta/alpha 1 ratio could be a reliable index for the estimation of the individual extent of CV damage. No association of vascular damage was observed with alpha3 power. On the other side, moderate hippocampal atrophy was related to an increase of alpha2 and alpha3 frequency power ratio. Our results show that different EEG markers are associated to vascular dementia and Alzheimer’s disease (AD). EEG markers could be expression of different global network pathological changes, helping in differentiation of prodromal AD from vascular demented patients. MCI stated that EEG markers could have a prospective value in differential diagnosis between vascular and degenerative MCI.
Impacto de la morbilidad en la salud de la población del País Vasco 2002-2007: una visión integral a través de las esperanzas de salud

Revista Espa?ola de Salud Pública , 2011, DOI: 10.1590/S1135-57272011000500006
Abstract: background: the estimation of the impact of morbidity on health is essential to health planning. the objective was to estimate this impact using disability free life expectancy, and to analyze whether the hypothetical elimination of various diseases would have led to a compression or expansion of morbidity. methods: cross-sectional study on the population of the basque country. data on mortality (2002-2006), health survey data (2007) and population based data were used. the impact of different groups of diseases on mortality rates, years of life and potential years of life lost (pyll) and disability (absolute number and rates) were calculated. an integrated analysis was also done, using disability free life expectancy (dfle), using the sullivan method. results: the diseases causing the greatest impact on mortality were tumours among men (35,2% and 39,3% of deaths and pyll respectively), and circulatory diseases (34,5% of deaths) and tumours (43,6% of pyll) among women. osteomuscular diseases had a major impact on disability, causing the 26,6% and the 45,2% of the total cases in men and women). circulatory diseases had the highest impact as a whole (4.2 years of dfle in men and 3.8 in women). however, osteomuscular diseases had the highest influence on years of life with disability. conclusions: the diseases which caused the overall greatest impact on mortality and disability were circulatory system related ones, tumors, and osteomuscular diseases. the elimination of this last group of diseases would have led to a morbidity compression, meaning the greatest reduction in life years with disability among all the causes.
