Monte Carlo Studies of Relations between Fractal Dimensions in Monofractal Data Sets
1998
Within the fractal approach to studying the distribution of seismic event locations, different fractal dimension definitions and estimation algorithms are in use. Although one expects that for the same data set, values of different dimensions will be different, it is usually anticipated that the direction of fractal dimension changes among different data sets will be the same for every fractal dimension. Mutual relations between the three most popular fractal dimensions, namely: the capacity, cluster and correlation dimensions, have been investigated in the present work. The studies were performed on the Monte Carlo generated data sets. The analysis has shown that dependence of the fractal …
Il Corridioio Meridiano come dispositivo territoriale per la competitività del Mezzogiorno
2008
Una nuova vision ha animato la redazione del Quadro Strategico Nazionale 2007-13 per il settore delle “infrastrutture e città”: una strategia reticolare di innovazione capace di orientare interventi di costituzione di cluster produttivi e innovativi, di connessione di piattaforme, di ricentralizzazione di aree urbane attraverso la riqualificazione dei nodi e la dotazione di servizi collettivi. La strategia mira soprattutto alla ridefinizione di funzioni di rango metropolitano in grado di potenziare il ruolo di Global Gateways che le città stanno progressivamente assumendo all'interno dei processi più avanzati di rigenerazione urbana e competitività territoriale, capaci di agire da “trasform…
Gas measurements from the Costa Rica–Nicaragua volcanic segment suggest possible along-arc variations in volcanic gas chemistry
2014
Obtaining accurate estimates of the CO2 output from arc volcanism requires a precise understanding of the potential along-arc variations in volcanic gas chemistry, and ultimately of the magmatic gas signature of each individual arc segment. In an attempt to more fully constrain the magmatic gas signature of the Central America Volcanic Arc (CAVA), we present here the results of a volcanic gas survey performed during March and April 2013 at five degassing volcanoes within the Costa Rica-Nicaragua volcanic segment (CNVS). Observations of the volcanic gas plume made with a multicomponent gas analyzer system (Multi-GAS) have allowed characterization of the CO2/SO2-ratio signature of the plumes …
How is motivational interviewing (un)related to self-determination theory: An empirical study from different healthcare settings.
2021
To explore how quality aspects and clients’ verbal behaviors in Motivational Interviewing sessions correspond with counsellors’ support of basic psychological needs described in Self-determination Theory, we conducted a mixed method study with quantitative analyses of transformed qualitative data from counselling sessions. Coding manuals identified if the counselling was consistent with Motivational Interviewing and the support of basic psychological needs. The study supported a conceptual relationship between motivational interviewing (MI) and self-determination theory (SDT), except for autonomy support which was conceptualized differently in the two approaches. Relational support in SDT a…
Multicomponent Exercise Training Combined with Nutritional Counselling Improves Physical Function, Biochemical and Anthropometric Profiles in Obese C…
2020
Aerobics or strength exercise plus diet interventions have been shown to counteract childhood obesity. However, little is known with regard to periodized multicomponent exercise interventions combined with nutritional counselling, which might be less demanding but more enjoyable and respectful of children and adolescents&rsquo
Assessment of tobacco dependence curricula in Italian dental hygiene schools
2013
The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or cl…
Pattern formation and spatial correlation induced by the noise in two competing species
2004
We analyze the spatio-temporal patterns of two competing species in the presence of two white noise sources: an additive noise acting on the interaction parameter and a multiplicative noise which affects directly the dynamics of the species densities. We use a coupled map lattice (CML) with uniform initial conditions. We find a nonmonotonic behavior both of the pattern formation and the density correlation as a function of the multiplicative noise intensity.

A research program combining the analysis of situated activity and the development of training tools: an example from elite sport This article presents an original program that combines research and This article presents an original program that combines research and training development. Between 1997 and 2002, several studies of the activity of expert table tennis players during matches were carried out within the framework of course-of-action theory (Theureau, 1992, 2004). These studies had been formally agreed on by coaches, athletes and researchers and responded to both sports needs and scientific interests. Matches were videotaped during international meetings and followed by self-conf…
Factors Affecting Male Song Evolution in Drosophila montana
2005
D. montana (a species of the D. virilis group) has spread over the northern hemisphere, populations from different areas showing both genetic and phenotypic divergence. The males of this species produce an elaborate courtship song, which plays a major role both in species recognition and in intraspecific mate choice. The genetic architecture and physical constraints, as well as the importance of the signal for species recognition, set boundaries within which this signal can vary. Within these limits, courtship song parameters may change, depending on the males' physical condition and on the environment they inhabit. Females are likely to affect song evolution by exerting directional selecti…
