Landslide inventory and rockfall risk assessment of a strategic urban area (Palermo, Sicily)
2019
This study concerns the assessment of the rockfall risk for two strategic sectors of the Mount Pellegrino, one of the most relevant place in the city of Palermo. During the last two decades, several rockfalls affected the study area setting up a serious threat to the people, structures and infrastructures preventing the economic and social development. For these landslides a detailed GIS inventory was realized; the most dangerous rockfalls occurred within the two study sectors. In both areas we have carried out detailed field surveys and the geo-mechanical characterization of the rock slopes. These analyses allowed to define the rock mass parameters, the set of discontinuities and the kinem…
Dentro il palazzo dell'arcivescovo. Un inventario palermitano del 1476
2019
Lo studio si propone di fare luce su alcuni aspetti legati alla vita dell’arcivescovado palermitano alla fine del XV secolo attraverso l’analisi dei beni mobili elencati in una fonte inedita che viene integralmente trascritta. Si tratta di un inventario compilato dal notaio Giacomo Randisi nel dicembre 1476, dopo la morte dell’arcivescovo Paolo Visconti, a evitare che i beni fossero sottratti alla Chiesa di Palermo o portati lontano dalla città: l'elenco degli oggetti esistenti nelle due sedi arcivescovili del Palazzo cittadino e in quello dello Scibene, consente di mettere a fuoco il contesto sociale, economico e culturale dell’arcivescovado palermitano e di gettare nuova luce su un monume…
Estimation of forest stand characteristics using individual tree detection, stochastic geometry and a sequential spatial point process model
2022
Airborne Laser Scanning (ALS) results in point-wise measurements of canopy height, which can further be used for Individual Tree Detection (ITD). However, ITD cannot find all trees because small trees can hide below larger tree crowns. Here we discuss methods where the plot totals and means of tree-level characteristics are estimated in such context. The starting point is a previously presented Horvitz–Thompson-like (HT-like) estimator, where the detectability is based on the larger tree crowns and a tuning parameter that models the detection condition. We propose a new method which is based on modeling the spatial pattern of hidden tree locations using a sequential spatial point process mo…
The first inventory of birds of prey in sicilian museum collections (Italy)
2020
Natural History Museums are places of scientific dissemination and informal education, and have a fundamental role in scientific research and in preserving the historical heritage of a territory and its biodiversity. The island of Sicily, thanks to its geographic position as an inter-continental bridge in the Mediterranean, presents a notable ornithological diversity, with both sedentary species and species that migrate between Africa and Europe. For this reason, and thanks to a strong hunting tradition, Sicilian collections also depict the avifaunal assemblage historically present in the region, particularly for birds of prey, the group we focus on because of its particular ecological char…
Management of Greenhouse Gas Emissions for Airport Inventories
2020
Greenhouse gases retain heat in the atmosphere since they absorb most of the Earth's outgoing long wave infrared radiation. The energy trapping alters the radiative balance that, in turn, modifies weather patterns at a global scale, progressively increasing the natural greenhouse effect. Heattrapping ability of some pollutants and primarily the carbon overload in the atmosphere as a result of human activities which have been protracted over a long period of time, has led to climate change and increase in global average temperature. In a long-term perspective, emission abatement from aviation sector has needed wide-ranging strategies. In this view an inventory of greenhouse gases can be a be…
Inwentaryzacja w aspekcie koncepcji rzetelnego i jasnego obrazu
2017
Cel – Zaprezentowanie inwentaryzacji jako podstawowego instrumentu weryfikacji zasobów majątku i kapitałów w celu prezentacji rzetelnego i jasnego obrazu sytuacji majątkowej i finansowej jednostki. Metodologia badania – Analiza literatury przedmiotu i przepisów prawnych (krajowych i międzynarodowych). Wynik – Wykazano, iż inwentaryzacja stanowi podstawowe narzędzie weryfikacji składników aktywów i pasywów przed ich ujęciem w sprawozdaniu finansowym. Sprzyja realizacji koncepcji rzetelnego i wiernego obrazu (true and fair view) w rachunkowości. Oryginalność/wartość – Wskazanie na przydatność inwentaryzacji w realizacji koncepcji wiernego i rzetelnego obrazu (true and fair view) na każdym eta…
Developing a Conceptual Framework for Investigating Communication Supporting Community Resilience
2015
In crisis management, cooperation within the response network is seen as crucial. Usually, this network refers to authorities and nongovernmental organizations, such as the Red Cross. However, the authors argue that to improve societal resilience one should take a broader overview of the actors involved in crisis preparedness and mitigation, and also include the public. With this in mind, the role of communication is scrutinized and a conceptual framework developed as a starting point for further investigation into how communication may be developed to strengthen a community approach to crisis management that includes citizen groups in the broader response network. A model is presented alon…
Secular rise in economically valuable personality traits
2017
Although trends in many physical characteristics and cognitive capabilities of modern humans are well-documented, less is known about how personality traits have evolved over time. We analyze data from a standardized personality test administered to 79% of Finnish men born between 1962 and 1976 (n = 419,523) and find steady increases in personality traits that predict higher income in later life. The magnitudes of these trends are similar to the simultaneous increase in cognitive abilities, at 0.2-0.6 SD during the 15-y window. When anchored to earnings, the change in personality traits amounts to a 12% increase. Both personality and cognitive ability have consistent associations with famil…
Development of a Chemistry Concept Inventory for General Chemistry Students at Norwegian and Finnish Universities
2018
A Chemistry concept inventory has been developed for assessing students’ learning and identifying alternative conceptions that students may have in general chemistry. The inventory aims at functioning as a tool for adjusting teaching practices in chemistry and is mainly aimed at assessing students’ learning during general chemistry courses. The inventory was administered as a post-test in a general chemistry course at the Norwegian University of Science and Technology (NTNU) in spring 2015, and evaluated using different statistical tests, focusing both on item analysis and the test as a whole. The results from this analysis indicated that the concept inventory is a reliable and discriminati…
Autonomous hyperspectral UAS photogrammetry for environmental monitoring applications
2014
Abstract. The unmanned airborne system (UAS) remote sensing using lightweight multi- and hyperspectral imaging sensors offer new possibilities for the environmental monitoring applications. Based on the accurate measurements of the way in which the object reflect and emit energy, wide range of affecting variables can be monitored. Condition for reliable applications is reliable and accurate input data. In many applications, installation of geometric and radiometric reference targets in the object area is challenging, for instance, in forest or water areas. On the other hand, UASs are often operated in very poor conditions, under clouds or under variable cloud cover. Our objective is to deve…
