STATUS OF ENVIRONMENTAL PROTECTION AS A SOURCE OF FINANCE FOR REGIONAL ECONOMIC DEVELOPMENT: MEASUREMENT OF ENVIRONMENTAL AND REGIONAL POLICY WITH TH…

2008

The present paper analyses spatial distribution of EU financial support for territories, where environmental protection is of high importance, and tests the measuring method based on the t‐statistic of sign frequency in order to apply the R. Fisher function's arcsin transformation. The measuring of EU fund distribution is based on the analysis of sign frequency in sample groups with sign frequency in all the municipalities of Latvia. There are 530 municipalities in Latvia, and in 100 of them environmental protection is of high importance. The author has concluded that Latvian municipalities with high environmental protection levels have significantly higher possibilities to obtain EU funds …

Dopo la firmitas. Prospettiva metabolista di architetture resilienti

2019

Identificata per millenni attraverso la sua capacità di durare identica nel tempo – secondo il paradigma della firmitas vitruviana - l’architettura contemporanea è invece chiamata oggi ad un adattamento dinamico alle mutazioni del suo contesto. L’emergenza climatica è l’epifenomeno più evidente fra quelli che hanno orientato la disciplina verso l’indeterminatezza programmatica, la flessibilità morfologica, gli approcci sistemici aperti. Lontana dall’essere un semplice adeguamento tecnico a nuove esigenze quantitative, l’architettura resiliente chiarisce progressivamente i suoi termini teorici e le sue derivazioni culturali. Un approccio genealogico che traccia la riformulazione di alcuni te…

Use of stable isotope analysis to evaluate the possible impact of fish migration on a lake biomanipulation

2007

1. A lake restoration project involving mass fish removals was started to improve further the water quality of a lake recovering from severe eutrophication. The effectiveness of such biomanipulation as a lake management option could be compromised if removed fish are rapidly replaced by large-scale immigration from a connected lake. 2. Stable isotope analysis (SIA) was used to examine the migrations of perch (Perca fluviatilis L.) and roach (Rutilus rutilus (L.)) between two connected lakes in central Finland, Jyvasjarvi and the larger Paijanne. Baseline δ15N signatures in primary consumers were significantly higher in Jyvasjarvi and this difference was reflected further up the food chain i…

Turtles on the trash track: loggerhead turtles exposed to floating plastic in the Mediterranean Sea

2019

Loggerhead turtles (Caretta caretta) spend most of their life in large marine areas occupying a variety of habitats where they are exposed to different types of threats. Among these, marine litter is known to pose a risk of entanglement or ingestion. Areas of risk exposure can be identified where the species overlap with litter accumulations, but gathering data on this highly mobile species and marine litter, especially in high sea areas, is challenging. Here we analysed five years of sea turtle and marine litter data collected by a network of research bodies along fixed trans-border transects in the Mediterranean Sea. Ferries were used as observation platforms to gather systematic data on …

Behavioural strategy of common bottlenose dolphins (Tursiops truncatus) in response to different kinds of boats in the waters of Lampedusa Island (It…

2013

Owing to the increase of boat-traffic in the ocean many studies have been conducted to determine the response of bottlenose dolphin (Tursiops truncatus) to this kind of disturbance. This species is affected by boats in various ways and the response depends on the behavioural state of the dolphin but also on the kind of vessel. This study aimed to determine the effect of motorboats and trawlers on dolphins' presence, permanence in the area and whistle parameters in Lampedusa waters (Italy). Sampling was carried out between May and December 2006 and between July and September 2009, using experimental passive acoustic monitoring systems (PAM); a total of 300 h of recordings and 3000 whistles w…

Local recruitment of Atlantic cod and putative source spawning areas in a coastal seascape

2021

Abstract Increased knowledge on connectivity is crucial to our understanding of the population dynamics, genetic structure, and biogeography of many coastal species. In coastal marine populations, the main factor for structuring is thought to be the degree of isolation and confinement, limiting genetic exchange between populations. However, many offshore populations use the coastal areas as nursery grounds, but venture back to natal spawning grounds as adults. Therefore, increased knowledge on the connectivity between coastal and offshore populations is crucial to ensure correct assessment of coastal living resources. Here, we combine genetic assignment data of Atlantic cod recruits sampled…

Predicting Heuristic Search Performance with PageRank Centrality in Local Optima Networks

2015

Previous studies have used statistical analysis of fitness landscapes such as ruggedness and deceptiveness in order to predict the expected quality of heuristic search methods. Novel approaches for predicting the performance of heuristic search are based on the analysis of local optima networks (LONs). A LON is a compressed stochastic model of a fitness landscape's basin transitions. Recent literature has suggested using various LON network measurements as predictors for local search performance.In this study, we suggest PageRank centrality as a new measure for predicting the performance of heuristic search methods using local search. PageRank centrality is a variant of Eigenvector centrali…

Plant hunting: exploring the behaviour of amateur botanists in the field

2021

We asked what are the behavioural and logistic preferences of professional and amateur botanists when exploring flora in the field. We extracted temporal and spatial data on vas- cular plant species occurrences from three datasets of Sicilian flora: a subset of iNaturalist, a dataset collected by a Facebook group focused on the flora of Sicily and a subset of the professional database European Vegetation Archive. We used the time span of individual contributor’s activity as a proxy of their commitment to collecting information about the flora of Sicily. Climate and landscape data were used to better characterize the spatial and temporal activity of data contributors. Finally, we assessed wh…

Ventricular Fibrillation and Tachycardia Detection Using Features Derived from Topological Data Analysis

2022

A rapid and accurate detection of ventricular arrhythmias is essential to take appropriate therapeutic actions when cardiac arrhythmias occur. Furthermore, the accurate discrimination between arrhythmias is also important, provided that the required shocking therapy would not be the same. In this work, the main novelty is the use of the mathematical method known as Topological Data Analysis (TDA) to generate new types of features which can contribute to the improvement of the detection and classification performance of cardiac arrhythmias such as Ventricular Fibrillation (VF) and Ventricular Tachycardia (VT). The electrocardiographic (ECG) signals used for this evaluation were obtained from…
