The Greying Church: The Impact of Life Expectancy on Religiosity

Many churches are concerned about older and dwindling congregations. We develop a theoretical framework to explain not only the downward trend in church attendance, but also the increase in the proportion of older people in the congregations. Religiosity depends positively on the expected social and spiritual benefits attached to religious adherence, as well as the probability of entering heaven in the afterlife. While otherworldly compensation in terms of salvation and spiritual benefits motivates religiosity, the costs of formal religion in terms of time allocated to communal activities and foregone income work in the opposite direction. We show that higher life expectancy discounts expected benefits in the afterlife and is hence likely to lead to postponement of religiosity. For this reason, religious organizations should be prepared to attract older members to their congregations, while emphasizing contemporaneous religious benefits to increase overall church attendance.

The age of movements along the insubric line West of Locarno (Northern Italy and southern Switzerland)

Permo-Mesozoic Canavese sediments are pinched in between the pre-Alpine high-grade metamorphic Ivrea Zone and the Alpine metamorphosed Sesia Zone along the Insubric Line W of Locarno. According to the ``illite crystallinity'' these sediments were deformed under anchi- and epizonal conditions. Synkinematically formed white mica in the mylonitized Canavese sediments yields the following K-Ar age ranges: 60-76 Ma at the southwestern end, 28-43 Ma in the central part and 19-26 Ma in the northeastern part of the Insubric Line W of Locarno. The youngest age group dates the main uplift and dextral strike-slip movements of the Insubric Line, comprising mylonites in the NE and cataclasites in the SW. This activity correlates with Late Oligocene to Early Miocene rapid cooling and uplift of the Central Alps.

Trypanosoma rangeli (Tejera, 1920) isolated from a sylvatic rodent (Echimys dasythrix) in Santa Catarina island, Santa Catarina state: first report of this trypanosome in southern Brazil

A trypanosome strain isolated from a sylvatic rodent (Echimys dasythrix) from Santa Catarina Island (Santa Catarina State, Brazil) was characterized by the following methods: experimental transmission and development in invertebrate hosts, morphometry, cross protection, complement sensitivity, lectin agglutination and isoenzyme profiles. Comparasions were made with standard Trypanosoma cruzi and T. rangeli strains. All methods except isoenzyne analysis led to the identification of the isolate as T. rangeli. The isoenzyme differences found could be explained on the basis of polymorphism. Therefore this is the first report of T. rangeli in southern Brazil, increasing the geographical distribution of this parasite.

Capacitat de segrest de carboni dels sòls de Sant Feliu de Guíxols, Santa Cristina d'Aro i Castell d'Aro (Baix Empordà)

En l’actualitat s’està generant una consciència col·lectiva sobre les repercussions que pot tenir l’escalfament global causat pels gasos d’efecte hivernacle (GEH). Amb l’objectiu de reduir les emissions de CO2 (segon gas responsable del canvi climàtic) cap a l’atmosfera, s’estan buscant possibles embornals de carboni. El sòl tot i ser el principal reservori de carboni del planeta, mai s’ha considerat com un factor important per la reducció de les emissions de GEH. Amb aquest projecte es pretén concretar quina és la capacitat de segrest de carboni per part dels sòls de les zones de St. Feliu de Guíxols i la Vall d’Aro, prenent en consideració les diferents variables que puguin influenciar.

Potencial d'aprofitament de recursos pluvials en zones urbanes al barri La Plana - Santa Bàrbara - Vallpineda del municipi de Sitges

Aquest estudi es centra en l’anàlisi de l’aprofitament d’aigües pluvials en sistemes urbans, concretament al barri de LaPlana - Sta. Bàrbara - Vallpineda de Sitges, en base als escenaris proposats que contemplen diferents criteris i paràmetres. La metodologia utilitzada que conjuga els resultats potencials de l’oferta amb els de la demanda d’aigua al barri permet la determinació del nivell d’autosuficiència hídrica del sistema. Els resultats mostren una alta autosuficiència del 90% en quant es s’apliquen estratègies de gestió hídrica ecoeficients i mesures domèstiques per a reduir la demanda domèstica del sector. A més, la tipologia de coberta inclinada i un major règim pluviomètric anual, s’ha observat afavoreixen l’augment d’aquest índex. Per tant, es considera apropiat realitzar un eficient aprofitament de l’aigua de pluja, com a recurs endogen local, donats els beneficis econòmics, ambientals i socials que comporta en una situació de dèficit hídric com la del municipi de Sitges.

Dispersão geopolítica da ocorrência de Fasciola hepatica no Estado de Santa Catarina, Brasil

During 12 years feces samples from cows, water buffaloes, sheeps and goats were examined by sequencial tamis filtration to show the occurence of Fasciola hepatica eggs. The material came from 129 municipalities of Santa Catarina State, and 5 g of feces per animal were examined. The occurrence of F. hepatica was confirmed in 64.82% of the municipalities. Considering the host, F. hepatica was confirmed in goats from Florianópolis, São José, São João Batista and Guaramirim municipalities; in sheeps from Brusque, Pomerode, Palhoça and São José; in water buffaloes from 9 and in cows from 86 municipalities. For this study, 13,762 feces samples were examined and in 3,814 the presence of eggs of F. hepatica was demonstrated. The percentage of occurence for host species was 27.86 in cows, 24.72 in water buffaloes, 16.92 in sheeps and 15.66 in goats. By the results it was demonstrated that Itajaí Valley at Southest Hidrographic Basin, in Santa Catarina State is an endemic area of F. hepatica, even though Uruguai Hidrographic Basin was not referred as a geographical record for this parasite.

Parental education and family characteristics: educational opportunities across cohorts in Italy and Spain

Drawing on data contained in the 2005 EU-SILC, this paper investigates the disparities in educational opportunities in Italy and Spain. Its main objective is to analyse the predicted probabilities of successfully completing upper-secondary and tertiary education for individuals with different parental backgrounds, and the changes in these probabilities across birth cohorts extending from 1940 to 1980. The results suggest that the disparities in tertiary education opportunities in Italy tend to increase over time. By contrast, the gap in educational opportunity in Spain shows a marked decrease across the cohorts. Moreover, by using an intuitive decomposition strategy, the paper shows that a large part of the educational gap between individuals of different backgrounds is “composed” of the difference in the endowment of family characteristics. Specifically, it seems that more highly educated parents are more able to endow their children with a better composition of family characteristics, which accounts for a significant proportion of the disparities in educational opportunity.

A key to genera and subgenera is presented and includes illustrations. This preliminary checklist and key is intended as a baseline for further study, the aim of which is to establish which species are of greatest economic importance.

Metropolitan Areas in Spain and Italy

Metropolitan areas concentrate the main share of population, production and consumption in OECD countries. They are likely to be the most important units for economic, social and environmental analysis as well as for the development of policy strategies. However, one of the main problems that occur when adopting metropolitan areas as units of analysis and policy in European countries is the absence of widely accepted standards for identifying them. This severe problem appeared when we tried to perform comparative research between Spain and Italy using metropolitan areas as units of analysis. The aim of this paper is to identify metropolitan areas in Spain and Italy using similar methodologies. The results allow comparing the metropolitan realities of both countries as well as providing the metropolitan units that can be used in subsequent comparative researches. Two methodologies are proposed: the Cheshire-GEMACA methodology (FUR) and an iterative version of the USA-MSA algorithm, particularly adapted to deal with polycentric metropolitan areas (DMA). Both methods show a good approximation to the metropolitan reality and produce very similar results: 75 FUR and 67 DMA in Spain (75% of total population and employment), and 81 FUR and 86 DMA in Italy (70% of total population and employment).

Diagnosi ambiental de la riera de Santa Coloma entre Santa Coloma de Farners i Riudarenes

A l’actualitat trobem nombrosos sistemes aquàtics alterats per diferents efectes d’origen antropogènic. Per tal d’evitar i/o disminuir aquests efectes va sorgir la Directiva Marc de l’Aigua (2000/60/CE) essent aquest un dels seus objectius. Aquest article descriu el funcionament hidrogeològic i l’estat ecològic de la riera de Santa Coloma, afluent de la Tordera (NE Catalunya), des de pràcticament el seu inici a Santa Coloma de Farners (Girona) fins a Riudarenes (Girona). S’intenta establir les possibles influències del funcionament hidrogeològic en l’estat ecològic a partir de dades piezomètriques, de cabal, fisicoquímiques i biològiques. Per aquesta última part s’han utilitzat indicadors biològics com l’índex d’hàbitat fluvial (IHF), avaluant l’hàbitat físic; l’índex de Qualitat del Bosc de Ribera (QBR), per determinar la qualitat ecològica de la zona de ribera; l’índex Biological Monitorig Working Party per a conques internes de Catalunya (BMWPC), per avaluar les diferents famílies de macroinvertebrats que hi viuen i l’índex ECOSTRIMED, una síntesi dels dos índex anteriors.

Diet diversity and the risk of laryngeal cancer: a case-control study from Italy and Switzerland.

Diet diversity (defined as the number of different foods consumed) has been considered an indicator of a healthy diet, and favorably related to the risk of several digestive tract cancers. We analyzed the relation between diet diversity and the risk of laryngeal cancer using data from a case-control study carried out between 1992 and 2000 in Italy and Switzerland. The subjects of the study were 527 patients with histologically confirmed incident cancers of the larynx and 1297 patients admitted for acute, non-neoplastic diseases, unrelated to tobacco or alcohol consumption. Total diversity was computed as the number of different foods (overall and within four food groups, i.e., vegetables, fruit, meat, and cereals) consumed at least once per week. A significant inverse association was observed for vegetable diversity (OR=0.41, 95% CI: 0.28-0.59, for the highest versus the lowest quartile) and fruit diversity (OR=0.40, 95% CI: 0.27-0.59). Conversely, a direct association was found for meat diversity (OR=1.67, 95% CI: 1.11-2.50), while no meaningful association was found for total diet and cereal diversity. The results were consistent across strata of age, alcohol drinking and tobacco smoking. This study suggests that a diet not only rich but also varied in fruit and vegetables is related to a decreased risk of laryngeal cancer risk.

Italy's urban waste metabolism

The problem of waste management is causing growing concern due to increasing generation rates, the emissions into soil, water and air, the social conflicts derived from the election of disposal sites and the loss of resources and energy among others. In this work, an innovative methodology is used to enable a better understanding of the waste generation and management system in Italy. Two new waste indicators are built to complement the conventional indicators used by official statistics. Then a multi-scale analysis of the Density of Waste Disposed (DWD) is carried out to highlight the territorial diversity of waste performances and test its contribution to detect plausible risky areas. Starting from Italian regions, the scale down goes on to the provincial level and, only for the region of Campania, the municipal one. First, the analysis shows that the DWD is able to complement the information provided by the conventional waste indicators. Second, the analysis shows the limitations of using a unique institutional solution to waste management problems. In this sense the multi-scale analysis provides with a more realistic picture of Italian waste system than using a single scale.

Regional value added in Italy over the long run (1891-2001): linking indirect estimates with official figures, and implications

This paper presents value added estimates for the Italian regions, in benchmark years from 1891 until 1951, which are linked to those from official figures available from 1971 in order to offer a long-term picture. Sources and methodology are documented and discussed, whilst regional activity rates and productivity are also presented and compared. Thus some questions are briefly reconsidered: the origins and extent of the north-south divide, the role of migration and regional policy in shaping the pattern of regional inequality, the importance of social capital, and the positioning of Italy in the international debate on regional convergence, where it stands out for the long run persistence of its disparities.
