Exploratory spatial data analysis of the distribution of regional per capita GDP in Europe, 1980-1995

2000

The aim of this paper is to study the dynamics of European regional per capita product over time and space. This purpose is achieved by using the recently developed methods of Exploratory Spatial Data Analysis. Using a sample of European regions over the 1980-1995 period, we find strong evidence of global and local spatial autocorrelation in per capita GDP throughout the period. The detection of clusters of high and low per capita products during the period is an indication of the persistence of spatial disparities between European regions. This analysis is finally refined by the investigation of the spatial pattern of regional growth. Key words:exploratory spatial data analysis; distributi…

Effects of Biochar Addition on Rill Flow Resistance

2021

The development of rills on a hillslope whose soil is amended by biochar remains a topic to be developed. A theoretical rill flow resistance equation, obtained by the integration of a power velocity distribution, was assessed using available measurements at plot scale with a biochar added soil. The biochar was incorporated and mixed with the arable soil using a biochar content BC of 6 and 12 kg m−2. The developed analysis demonstrated that an accurate estimate of the velocity profile parameter Гv can be obtained by the proposed power equation using an exponent e of the Reynolds number which decreases for increasing BC values. This result pointed out that the increase of biochar content dump…

Application of Geostatistical Tools to the Geochemical Characterization of the Peloritani Mts (Sicily, Italy) Aquifers

2021

Sources of groundwater contaminants in inhabited areas, located in complex geo-tectonic contexts, are often deeply interlocked, thus, making the discrimination between anthropic and natural origins difficult. In this study, we investigate the Peloritani Mountain aquifers (Sicily, Italy), using the combination of probability plots with concentration contour maps to retrieve an overall view of the groundwater geo-chemistry with a special focus on the flux of heavy metals. In particular, we present a methodology for integrating spatial data with very different levels of precision, acquired before and during the “geomatic era”. Our results depict a complex geochemical layout driven by a geo-puz…

The influence of geography on the spatial agglomeration of production in the European Union

2012

Abstract We investigate the relative impact of geographic features on the location of production in the European Union. Specifically, we attempt to quantify how much of the spatial pattern of GDP can be attributed to exogenous first-nature elements alone and how much can be derived from endogenous second-nature factors. In order to disentangle both effects empirically, we control for second-nature factors. A method based on the decomposition of the per capita GDP variance is applied to a panel of 1,171 European NUTS 3 regions for 2006. We demonstrate that variable and model misspecifications may bias results unless proper allowance is made for spatial autocorrelation and spatial heterogenei…

The Paper Industry in Germany, 1800–2000

2012

Germany is the biggest paper exporter in the world, the biggest paper producer in Europe and the fourth biggest producer in the world. It is also the biggest market in Europe and a major export market for European pulp producers. However, only three German pulp and paper companies made it to the top 100 list of the industry in 2010 and none made it into the top 50 (PPI 2011). This article describes the development of the German industry from the beginning of the nineteenth century to the present in order to explain the factors contributing to this unusual state of affairs in a country which, during the second Industrial Revolution, created major players in the new global oligopolies in chem…

Yield and Fruit Quality Characterization of Eight Old Sicilian Apple Cultivars

2011

In this trial, we examined the quality of eight old Sicilian apple cultivars (‘Cannamelo’, ‘Cardinale’, ‘Gelata Cola’, ‘Gelata’, ‘Granatino’, ‘San Giuseppe’, ‘Virticchiaro’, ‘Zitella’) and a commercial one (‘Annurca’ traditional clone) through bio-agronomic performances and chemical-physical analyses. We also analyzed flowering time, ripening time, pomological characteristics, and generated a specific descriptor list that indicates a great variability among the cultivars. The data obtained showed interesting characteristics in ‘Granatino’, ‘Virticchiaro’, and ‘Zitella’, such as total soluble solid, fruit size, peel cover color, yield efficiency, and crop load.

Molecular and morphological diversity of on-farm hazelnut (Corylus avellana L.) landraces from southern Europe and their role in the origin and diffu…

2013

Hazelnut (Corylus avellana L.) is a traditional nut crop in southern Europe. Germplasm exploration conducted on-farm in five countries (Portugal, Spain, Italy, Slovenia, and Greece) identified 77 landraces. The present work describes phenotypic variation in nut and husk traits and investigates genetic relationships using ten simple sequence repeat (SSR) markers among these landraces, 57 well-known references cultivars, and 19 wild accessions. Among the 77 landraces, 42 had unique fingerprints while 35 showed a SSR profile identical to a known cultivar. Among the 42 unique landraces, morphological observations revealed high phenotypic diversity, and some had characteristics appreciated by th…

Centennial olive trees as a reservoir of genetic diversity

2011

†Background and Aims Genetic characterization and phylogenetic analysis of the oldest trees could be a powerful tool both for germplasm collection and for understanding the earliest origins of clonally propagated fruit crops. The olive tree (Olea europaea L.) is a suitable model to study the origin of cultivars due to its long lifespan, resulting in the existence of both centennial and millennial trees across the Mediterranean Basin. †Methods The genetic identity and diversity as well as the phylogenetic relationships among the oldest wild and cultivated olives of southern Spain were evaluated by analysing simple sequence repeat markers. Samples from both the canopy and the roots of each tr…

The domestication and spreading of grapevine as well as the gene flow history had been described in many studies. We used a high-quality 7k SNP dataset of 1,038 Eurasian grape varieties with unique profiles to assess the population genetic diversity, structure, and relatedness, and to infer the most likely migration events. Comparisons of putative scenarios of gene flow throughout Europe from Caucasus helped to fit the more reliable migration routes around the Mediterranean Basin. Approximate Bayesian computation (ABC) approach made possible to provide a response to several questions so far remaining unsolved. Firstly, the assessment of genetic diversity and population structure within a we…

Jotain uutta, jotain vanhaa, jotain lainattua : ikääntyneiden perhehoito Suomessa

2017

Tässä artikkelissa tarkastellaan ikääntyneiden perhehoitoa, jolla tarkoitetaan ikääntyneen henkilön lyhyt-, osa-aikais- tai pitkäaikaishoitoa ja asumista perhehoitajan kodissa. Artikkelin tarkoituksena on tunnistaa tekijöitä, jotka ovat perhehoidon taustalla ja joiden varassa perhehoitoa kehitetään ikääntyneiden hoivan yhdeksi vaihtoehdoksi. Lisäksi artikkelissa tarkastellaan perhehoitoa hoivapoliittisena ratkaisuna julkisen ja yksityisen rajalla semiformaaliuden ja (de)domestikaation käsitteiden kautta. Aineistona käytetään eduskunnan täysistuntojen pöytäkirjoja sekä perhehoito- ja perhehoitajalakeja ja näiden lakien hallituksen esityksiä, joita analysoidaan Carol Bacchin WPR-metodin avull…
