Fuentes agrarias pre catastrales valencianas. Su utilidad geográfica
1998
Valencia agrarian precatastral sources. Its geographical utility. The socalled Llibres de Values de la Peyta and Cap-patrons are the oldest agrarian census in Valencia. As a geographic source, they give information about the properties, their division into plots, and about the types of lands and crops. They also make possible an approximate cartographic representation of all this.
Who Moves to Depressed Regions? An Analysis of Migration Streams in Finland in the 1990s
2002
Depressed regions typically lose a large number of migrants but simultaneously are destination regions for some migrants. This study analyzes those people who decided to move to depressed regions in Finland in 1993-1996. The analysis is based on a 1 percent sample drawn from the Finnish longitudinal census. The results show that migration into depressed regions is also a selective process. Return migration is only one part of this migration. However, the more educated an individual is, the more likely she or he is to move to a flourishing region. The process of concentration of human capital is reinforced by interregional migration.
Desigualdades y mortalidad por cirrosis en varones (Zaragoza, 1996-2003)
2011
ResumenObjetivosAnalizar diferencias geográficas en la mortalidad por cirrosis hepática, en varones, en la provincia de Zaragoza, y su posible asociación con indicadores socioeconómicos, así como identificar la adecuación, en el ámbito rural, del índice de privación del proyecto MEDEA.MétodosLa unidad geográfica de análisis para Zaragoza capital fue la sección censal, y para el resto de la provincia el municipio. Para cada unidad de análisis se calculó la razón de mortalidad estandarizada cruda y suavizada mediante un modelo lineal generalizado mixto bayesiano. Se calculó un índice sintético de privación y se incluyó en el modelo en cuartiles. También se realizó el análisis exploratorio inc…
Indagine comparativa sulla popolazione nidificante di Fratino Charadrius alexandrinus (Aves, Charadriiformes) nelle saline della Provincia di Trapani
2016
Comparative survey on the population of the Kentish plover Charadrius alexandrinus in the salt pans of Trapani province. This paper deals with a 2016 census of the breeding population of the Kentish plover in the saltpans of trapani and of the Stagnone di marsala. In the same area a previous census of this species was carried out forty years ago by Massa (1977). the comparison between data collected in the 1970s and in 2016 reveals that the population of the Kentish plover has been dramatically declining, with 70% decrease in the overall area (ca. 1,230 ha). Although responsibile for an additional 8% reduction of wetlands in the last few decades, direct human intervention is not likely to b…
Retirement Age Across Countries: The Role of Occupations
2011
Cross-country variation in effective retirement age is usually attributed to institutional differences that affect individuals’ incentives to retire. This paper suggests a different approach to explain this variation. Since working individuals in different occupations naturally retire at different ages, the composition of occupations within an economy matters for its average effective retirement age. Using U.S. Census data we infer the average retirement age by occupation, which we then use to predict the retirement age of 38 countries, using the occupational distribution of these countries. Our findings suggest that the differences in occupational composition explain up to 38% of the obser…
Disadvantaged neighborhoods and the spatial overlap of substantiated and unsubstantiated child maltreatment referrals
2019
Abstract Background Considerable debate exists on whether the substantiation decision is a reliable measure for rates of maltreatment. Studies have shown that risks among children victims of maltreatment versus children investigated but unsubstantiated are similar. Objective This paper aims to respond to two research questions: (1) Do most child maltreatment referrals, substantiated and unsubstantiated, come from the same neighborhoods? (2) Do substantiated and unsubstantiated referrals share the same neighborhood risk factors? Participants and settings We used geocoded data from substantiated (n = 1799) and unsubstantiated (n = 1638) child maltreatment referrals in Valencia, Spain (2004–20…
Two-level resolution of relative risk of dengue disease in a hyperendemic city of Colombia.
2018
Risk maps of dengue disease offer to the public health officers a tool to model disease risk in space and time. We analyzed the geographical distribution of relative incidence risk of dengue disease in a high incidence city from Colombia, and its evolution in time during the period January 2009—December 2015, identifying regional effects at different levels of spatial aggregations. Cases of dengue disease were geocoded and spatially allocated to census sectors, and temporally aggregated by epidemiological periods. The census sectors are nested in administrative divisions defined as communes, configuring two levels of spatial aggregation for the dengue cases. Spatio-temporal models including…
Ethnobotanical study in the Madonie Regional Park (Central Sicily, Italy)—Medicinal use of wild shrub and herbaceous plant species
2013
Abstract Ethnopharmacological relevance This paper illustrates the results of an ethnobotanical study carried out in the Madonie Regional Park (Central Sicily, Italy). It specifies the medicinal uses of plants in the study area and contains the results of a quantitative analysis carried out for the first time in an area noted for its high degree of biodiversity. It also introduces 28 species not previously accounted for in the area of study for their medicinal uses, highlighting Silene flos-cuculi L. Greuter & Burdet, little known as medicinal in the Mediterranean area. Aim of the study To understand to what extent current knowledge on medicinal-use plants is still an element of the culture…
Does the longevity of one or both parents influence the health status of their offspring?
2013
According to the findings of some recent studies, the centenarians' offspring appear to represent a promising model for research on longevity and healthy aging. This study compares the health status and the functional status of three groups of subjects: 1. individuals with two long-lived parents (one of whom centenarian), 2. individuals with only one long-lived (centenarian) parent, and 3. individuals with no long-lived parents. The goal is to verify whether the centenarians' offspring display any advantage over the offspring of both non-long-lived parents and to evaluate whether the longevity of the non centenarian parent provides a further advantage. A total of 374 subjects (mean age appr…
Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities
2011
incluye "Erratum to: Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities" BACKGROUND: Intra-urban inequalities in mortality have been infrequently analysed in European contexts. The aim of the present study was to analyse patterns of cancer mortality and their relationship with socioeconomic deprivation in small areas in 11 Spanish cities. METHODS: It is a cross-sectional ecological design using mortality data (years 1996-2003). Units of analysis were the census tracts. A deprivation index was calculated for each census tract. In order to control the variability in estimating the risk of dying we used Bayesian models. We present the RR of the censu…
