Conflict, Peace and Security in Africa: an Assessment and New Questions After 50 Years of African Independence

Since the independence processes in the African continent, armed conflicts, peace and security have raised concern and attention both at the domestic level and at the international scale. In recent years, all aspects have undergone significant changes which have given rise to intense debate. The end of some historical conflicts has taken place in a context of slight decrease in the number of armed conflicts and the consolidation of post-conflict reconstruction processes. Moreover, African regional organizations have staged an increasingly more active internal shift in matters related to peace and security, encouraged by the idea of promoting “African solutions to African problems”. This new scenario, has been accompanied by new uncertainties at the security level and major challenges at the operational level, especially for the African Union. This article aims to ascertain the state of affairs on all these issues and raise some key questions to consider.

Health care utilization among immigrants and native-born populations in 11 European countries. Results from the Survey of Health, Ageing and Retirement in Europe

Objective: This study examines health care utilization of immigrants relative to the native-born populations aged 50 years and older in eleven European countries. Methods. We analyzed data from the Survey of Health Aging and Retirement in Europe (SHARE) from 2004 for a sample of 27,444 individuals in 11 European countries. Negative Binomial regression was conducted to examine the difference in number of doctor visits, visits to General Practitioners (GPs), and hospital stays between immigrants and the native-born individuals. Results: We find evidence those immigrants above age 50 use health services on average more than the native-born populations with the same characteristics. Our models show immigrants have between 6% and 27% more expected visits to the doctor, GP or hospital stays when compared to native-born populations in a number of European countries. Discussion: Elderly immigrant populations might be using health services more intensively due to cultural reasons.

Health of Immigrants in European countries

The health of older immigrants can have important consequences for needed social support and demands placed on health systems. This paper examines health differences between immigrants and the nativeborn populations aged 50 years and older in 11 European countries. We examine differences in functional ability, disability, disease presence and behavioral risk factors, for immigrants and non-immigrants using data from the Survey of Health, Aging and Retirement in Europe (SHARE) database. Among the 11 European countries, migrants generally have worse health than the native population. In these countries, there is a little evidence of the “healthy migrant” at ages 50 years and over. In general, it appears that growing numbers of immigrants may portend more health problems in the population in subsequent years.

Factors associated with active aging in Finland, Poland, and Spain

BACKGROUND: Continuous population aging has raised international policy interest in promoting active aging (AA). AA theoretical models have been defined from a biomedical or a psychosocial perspective. These models may be expanded including components suggested by lay individuals. This paper aims to study the correlates of AA in three European countries, namely, Spain, Poland, and Finland using four different definitions of AA. METHODS: The EU COURAGE in Europe project was a cross-sectional general adult population survey conducted in a representative sample of the noninstitutionalized population of Finland, Poland, and Spain. Participants (10,800) lived in the community. This analysis focuses on individuals aged 50 years old and over (7,987). Four definitions (two biomedical, one psychosocial, and a complete definition including biomedical, psychosocial, and external variables) of AA were analyzed. RESULTS: Differences in AA were found for country, age, education, and occupation. Finland scored consistently the highest in AA followed by Spain and Poland. Younger age was associated with higher AA. Higher education and occupation was associated with AA. Being married or cohabiting was associated with better AA compared to being widowed or separated in most definitions. Gender and urbanicity were not associated with AA, with few exceptions. Men scored higher in AA only in Spain, whereas there was no gender association in the other two countries. Being widowed was only associated with lower AA in Poland and not being married was associated with lower AA in Poland and Finland but not Spain. CONCLUSIONS: Associations with education, marital status, and occupation suggest that these factors are the most important components of AA. These association patterns, however, seem to vary across the three countries. Actions to promote AA in these countries may be addressed at reducing inequalities in occupation and education or directly tackling the components of AA lacking in each country.

Tendències temporals de la mortalitat per càncer de fetge a Catalunya: periode 1983-2002 i projeccions pel 2005

Estudi elaborat a partir d’una estada al Finnish Cancer Registry a Helsinki, Finlandia entre setembre i novembre del 2006. Davant l’increment dels tumors hepàtics en països industrialitzats, s’avaluen les tendències temporals de la malaltia hepàtica a Catalunya durant el període 1983-2002 i s’estima la tendència futura a partir de l’any 2005. L’estudi s’ha basat en dades del Registre de Mortalitat de Catalunya i de l’Institut d’Estadística de Catalunya. La malaltia hepàtica inclou diverses tipologies de tumors hepàtics i la cirrosi hepàtica. Els models edad-període-cohort s’han emprat per estimar els efectes període de mortalitat i cohort de naixement. Els resultats han mostrat que les taxes de mortalitat per cirrosi han disminuït en ambdós sexes, exceptuant els homes d’entre els 35-50 anys, pels quals la mortalitat es mantingué estable. S’han observat increments en la mortalitat per carcinoma hepatocel•lular i en els tumors de vies biliars intrahepàtiques, mentre que les projeccions mostren estabilitat en la tendència d’aquestes malalties durant el període 2005-2009. Les tendències de la mortalitat per malaltia hepàtica constatades poden ser degudes a la implementació de teràpies noves, nous mètodes de diagnòstic, infecció pel virus de l’hepatitis C d’altres factors desconeguts.

Probiotic microorganisms: 100 years of innovation and efficacy. Modes of action

AbstractArticle StructureFigures and TablesReferences Benefits from probiotic micro-organisms have been recognised for over 100 years, and as being useful in poultry for 50 years. Fuller (1989) redefined probiotics as ‘a live microbial feed supplement which beneficially affects the host animal by improving its intestinal microbial balance’. Benefits derived from this improved intestinal microbial balance could be reflected in performance or prevention of pathogen colonisation. Probiotic micro-organisms use in poultry production has been widely accepted and new opportunities arose from the 2006 EU ban on antimicrobial growth promoters. The majority of microbial products for compound feeds are made up from a relatively small number of micro-organisms that are normally present in the GI tract. They include non-sporulated bacteria, sporulated bacteria, fungi or yeasts; and presented from single to multi-strain products. A review on the proposed modes of action is presented including recent approaches to quorum sensing interference

Evolució de la vegetació de l’antic estany de Sils (la Selva) en els darrers 50 anys

The historical evolution of vegetation in the former Sils Pond (la Selva) during the second half of the 20th century is described through the study of past(Bolòs, 1954; Vilar, 1981) and present-day (Mercadal, 2002) vegetation cartography, the first aerial photographs (1956 and 1980) and current orthophotos (2000). This inland pool was finally drained in 1851 and most of its area was converted into meadows (Gaudinio fragilis-Arrhenatheretum elatioris Br.-Bl. in Br.-Bl., Roussine & Nègre 1952), a semi cultural community which was very distinct florally, for the Mediterranean region. The results demonstrate that in the last 50 years changes in land use have transformed the former landscape, which was prominently meadow-like and grain-producing, into woodlands, wet grasslands, developed areas and sub-Mediterranean forests, with the consequent loss of meadow areas and floristic diversity. In response, based on historical cartography, we propose spaces to prioritize for recovery and management such as meadow areas

Estudi sociològic del lleure al món rural de Catalunya i Guatemala. L'oci a la població de 50 a 70 anys de Malla i San Juan la Laguna, semblances i diferències

L’estudi que es presenta a continuació té l’objectiu de comprendre quina és la realitat ociosa de les persones de 50 a 70 anys als municipis de Malla (Catalunya, Espanya) i de San Juan la Laguna (Sololá, Guatemala) des de la perspectiva humanista en termes de concepció i pràctica, i veure quina és la influència i la força que prenen les característiques de la societat en la qual es desenvolupa. Per tal de dur-ho a terme, primerament s’ha realitzat un procés d’aproximació respecte el concepte de l’oci, i una recerca concreta vers l’oci humanista. A partir d’aquí, s’ha fet l’estudi amb una mostra formada per deu persones del municipi de Malla i deu membres de San Juan la Laguna que es troben entre els 50 i 70 anys, i amb unes condicions econòmiques i uns estils de vida diferents. Per tal de realitzar la recerca i l’anàlisi de l’oci humanista en els contexts de Malla i San Juan la Laguna s’ha emprat una metodologia qualitativa, i s’ha utilitzat l’instrument corresponent a l’entrevista. Aquesta ha estat elaborada prenent com a marc de referència la metodologia de la Grounded Theory (Glaser y Strauss, 1967). El projecte també compte amb una vessant d’etnografia. Els resultats que s’han obtingut demostren que hi ha una presència significativa de l’oci humanista en els contexts analitzats, però que en el cas de San Juan la Laguna aquest esdevé un element en construcció.

Rapid increase in incidence of breast ductal cancer in situ in Girona, Spain 1983-2007

Introduction: The aim of this study was to describe breast ductal cancer in situ (DCIS) incidence trends in women in the Girona province during a period of 25 years. The influence of age, use of mammography and implementation of the breast cancer screening programs was explored. Incidence of subsequent invasive breast cancers (IBC) and DCIS treatment was also considered. Materials and Methods: Cases diagnosed with primary pure DCIS (n=416) during 1983-2007 were extracted from the population-based Girona Cancer Registry. The estimated annual percent change was estimated using joinpoint analysis. Results: DCIS incidence showed a sharp rise until 1998, followed by a less marked upward trend. Among women aged 50-69 the increase was particularly important between 1992 and in 1996, reflecting the spread in mammography use. Conclusion: The upward trend of DCIS was mainly related to an increase in mammography use either opportunistic or as a result of screening implementation

Visual impairment and multimorbidity in a representative sample of the Spanish population

BACKGROUND: In the context of population aging, visual impairment has emerged as a growing concern in public health. However, there is a need for further research into the relationship between visual impairment and chronic medical conditions in the elderly. The aim of our study was to examine the relationship between visual impairment and three main types of co-morbidity: chronic physical conditions (both at an independent and additive level), mental health and cognitive functioning. METHODS: Data were collected from the COURAGE in Europe project, a cross-sectional study. A total of 4,583 participants from Spain were included. Diagnosis of chronic medical conditions included self-reported medical diagnosis and symptomatic algorithms. Depression and anxiety were assessed using CIDI algorithms. Visual assessment included objective distance/near visual acuity and subjective visual performance. Descriptive analyses included the whole sample (n = 4,583). Statistical analyses included participants aged over 50 years (n = 3,625; mean age = 66.45 years) since they have a significant prevalence of chronic conditions and visual impairment. Crude and adjusted binary logistic regressions were performed to identify independent associations between visual impairment and chronic medical conditions, physical multimorbidity and mental conditions. Covariates included age, gender, marital status, education level, employment status and urbanicity. RESULTS: The number of chronic physical conditions was found to be associated with poorer results in both distance and near visual acuity [OR 1.75 (CI 1.38-2.23); OR 1.69 (CI 1.27-2.24)]. At an independent level, arthritis, stroke and diabetes were associated with poorer distance visual acuity results after adjusting for covariates [OR 1.79 (CI 1.46-2.21); OR 1.59 (CI 1.05-2.42); OR 1.27 (1.01-1.60)]. Only stroke was associated with near visual impairment [OR 3.01 (CI 1.86-4.87)]. With regard to mental health, poor subjective visual acuity was associated with depression [OR 1.61 (CI 1.14-2.27); OR 1.48 (CI 1.03-2.13)]. Both objective and subjective poor distance and near visual acuity were associated with worse cognitive functioning. CONCLUSIONS: Arthritis, stroke and the co-occurrence of various chronic physical diseases are associated with higher prevalence of visual impairment. Visual impairment is associated with higher prevalence of depression and poorer cognitive function results. There is a need to implement patient-centered care involving special visual assessment in these cases.

Multimorbidity patterns in a national representative sample of the Spanish adult population.

BACKGROUND: In the context of population aging, multimorbidity has emerged as a growing concern in public health. However, little is known about multimorbidity patterns and other issues surrounding chronic diseases. The aim of our study was to examine multimorbidity patterns, the relationship between physical and mental conditions and the distribution of multimorbidity in the Spanish adult population. METHODS: Data from this cross-sectional study was collected from the COURAGE study. A total of 4,583 participants from Spain were included, 3,625 aged over 50. An exploratory factor analysis was conducted to detect multimorbidity patterns in the population over 50 years of age. Crude and adjusted binary logistic regressions were performed to identify individual associations between physical and mental conditions. RESULTS: THREE MULTIMORBIDITY PATTERNS ROSE: 'cardio-respiratory' (angina, asthma, chronic lung disease), 'mental-arthritis' (arthritis, depression, anxiety) and the 'aggregated pattern' (angina, hypertension, stroke, diabetes, cataracts, edentulism, arthritis). After adjusting for covariates, asthma, chronic lung disease, arthritis and the number of physical conditions were associated with depression. Angina and the number of physical conditions were associated with a higher risk of anxiety. With regard to multimorbidity distribution, women over 65 years suffered from the highest rate of multimorbidity (67.3%). CONCLUSION: Multimorbidity prevalence occurs in a high percentage of the Spanish population, especially in the elderly. There are specific multimorbidity patterns and individual associations between physical and mental conditions, which bring new insights into the complexity of chronic patients. There is need to implement patient-centered care which involves these interactions rather than merely paying attention to individual diseases.

Why the EU does not Have an Independent Competition Agency: French Interests and Transaction Costs in Early European Integration

A major achievement of new institutionalism in economics and political science is the formalisation of the idea that certain policies are more efficient when administered by a politically independent organisation. Based on this insight, several policy actors and scholars criticise the European Community for relying too much on a multi-task, collegial, and politicised organisation, the European Commission. This raises important questions, some constitutional (who should be able to change the corresponding procedural rules?) and some political-economic (is Europe truly committed to free and competitive markets?). Though acknowledging the relevance of legal and normative arguments, this paper contributes to the debate with a positive political-scientific perspective. Based on the view that institutional equilibria raise the question of equilibrium institutions, it shows that collegiality was (a) an equilibrium institution during the Paris negotiations of 1950-51; and (b) an institutional equilibrium for the following 50 years. The conclusion points to some recent changes in the way that European competition policy is implemented, and discusses how these affect the “constitutional” principle of collegial European governance.

The effects of feeding Karlodinium veneficum (PLY # 103; Gymnodinium veneficum Ballantine) to the blue mussel Mytilus edulis

The effects of exposure to the type species for Karlodinium veneficum (PLY # 103) on immune function and histopathology in the blue mussel Mytilus edulis were investigated. Mussels from Whitsand Bay, Cornwall (UK) were exposed to K. veneficum (PLY # 103) for 3 and 6 days. Assays for immune function included total and differential cells counts, phagocytosis and release of extra cellular reactive oxygen species. Histology was carried out on digestive gland and mantle tissues. The toxin cell quota for K. veneficum (PLY #103) was measured by liquid chromatography-mass spectrometry detecting two separable toxins KvTx1 (11.6 ± 5.4 ng/ml) and KvTx2 (47.7 ± 4.2 ng/ml). There were significant effects of K. veneficum exposure with increasing phagocytosis and release of reactive oxygen species following 6 days exposure. There were no significant effects on total cell counts. However, differential cell counts did show significant effects after 3 days exposure to the toxic alga. All mussels produced faeces but not pseudofaeces indicating that algae were not rejected prior to ingestion. Digestive glands showed ingestion of the algae and hemocyte infiltration after 3 days of exposure, whereas mantle tissue did not show differences between treatments. As the effects of K. veneficum were not observed in the mantle tissue it can be hypothesized that the algal concentration was not high enough, or exposure long enough, to affect all the tissues. Despite being in culture for more than 50 years the original K. veneficum isolate obtained by Mary Parke still showed toxic effects on mussels.

El Rossinyol torna de França : La realitat del cant coral al tombant del segle XXI

Estudi del moviment coral a Catalunya des d'un punt de vista antropològic i social. Fa èmfasi en el paper dels repertoris del cant coral i en la manera com aquests repertoris reflecteixen la història social i cultural del món del cant coral a Catalunya. Estudi d'un microcosmos: l'Orfeó de les Corts, la seva trajectòria musical i la seva trajectòria com a entitat en els darrers 50 anys a Barcelona. S'analitza què hi ha més enllà del fet coral: el tipus de música, el fet de cantar en grup, els tipus d'associacions, la procedència, els objectius i la filosofia, les inquietuds dels cantaires i les preferències dels directors, per tal de copsar les dinàmiques socials i musicals del moviment coral.
