A new species of Isatis (Brassicaceae) from the Pollino National Park (Basilicata, S Italy)
2015
A new species, Isatis raimondoi (Brassicaceae) is described from Mt Alpi in the Pollino National Park (Basilicata, Southern Italy). Its relationships with the other species of Isatis occurring in Italy are examined.
Discovery of a second locality for the narrow endemic Anthemis ismelia (Asteraceae) in NW Sicily
2017
A new population of Anthemis ismelia (Asteraceae) has been discovered on Mt Pecoraro (Cinisi, NW Sicily), a limestone headland at about 14 km from Mt Gallo (Palermo), the locus classicus et unicus of this species described in 1884. Taxonomic framework, distribution update, habitat characterisation, ecology and phytosociological framework are provided, as well as meta-population numerical estimates and risk status assessment.
Magnetic Properties Experiments on the Mars Exploration Rover Spirit at Gusev Crater
2004
The magnetic properties experiments are designed to help identify the magnetic minerals in the dust and rocks on Mars—and to determine whether liquid water was involved in the formation and alteration of these magnetic minerals. Almost all of the dust particles suspended in the martian atmosphere must contain ferrimagnetic minerals (such as maghemite or magnetite) in an amount of ∼2% by weight. The most magnetic fraction of the dust appears darker than the average dust. Magnetite was detected in the first two rocks ground by Spirit.
A Lisrel Model for Country Risk Assessment
2015
As German industry is very much export-oriented, country risk assessment is a major problem in international marketing for German suppliers. The data from several country risk assessment indicator concepts were collected and put into a LISREL model to test which hypothesized relationships between the measured variables and hypothetical constructs can be empirically proved. A structural equation model will be developed to be able to test the causal relationships between the hypothetical constructs over time (multi-wave, multi-variable model).
Assessing competence: The European survey on aging protocol (ESAP)
2003
<i>Objectives:</i> The main goal of this research project was to translate and adapt the European Survey on Ageing Protocol (ESAP) to 7 European countries/cultures. This article presents preliminary results from the ESAP, the basic assessment instrument of EXCELSA (European Longitudinal Study of Aging). <i>Methods:</i> 672 individuals aged 30–85, selected through quota sampling (by age, gender, education and living conditions), participated in this study, with 96 subjects from each of the 7 European countries. The basic research protocol for assessing competence and its determinants was designed to be administered in a 90-min in-home face-to-face interview. It contai…
Poor Physical Performance Predicts Future Onset of Depression in Elderly People: Progetto Veneto Anziani Longitudinal Study.
2016
Abstract Background. Reduced physical performance is predictive of deleterious outcomes in older adults. Data considering objective physical performance and incident depression are sparse. Objective. The objective of this study was to investigate during a 4-year study whether objective physical performance can predict incident depression among older adults who do not have depression at the baseline. Design. This was a longitudinal study. Methods. From 3,099 older people initially enrolled in the Progetto Veneto Anziani study, 970 participants without depression at the baseline were included (mean age = 72.5 years; 54.6% women). Physical performance measures included the Short Physical Perfo…
Active commuting to school among preschool-aged children and its barriers: An exploratory study in collaboration with parents
2018
Abstract Introduction Active commuting to school (ACS) contributes to children's overall physical activity levels, providing multiple health benefits. However, studies analyzing the modes of transport used among children of preschool age (3–5 years), as well as which factors affect ACS, are scant. Methods We performed a mixed-method study, initially taking a qualitative approach in collaboration with parents of preschool-aged children (i.e., focus groups), to identify their usual modes of commuting to school with their offspring. Following this, we asked parents, through a questionnaire, about the modes of transport to school they use with their children, as well as the weekly use-frequency…
Convergence of European regions (an approach by spatial econometrics)
2000
The aim of this paper is the analysis of spatial dependence in convergence processes applied to European regions. First, we apply the recently developed exploratory spatial data analysis (Anselin, 1996) in order to describe more precisely the geographical dynamics of European regional income growth patterns. New insights are brought to the usual cr-convergence measure, which hides geographical patterns that may fluctuate over time. Second, we test the presence of spatial autocorrelation in /^-convergence models by using spatial econometrics methods (Anselin, 1988 ; Anselin and Florax, 1995). We compare the results with and without spatial autocorrelation in order to assess the effect of geo…
