Il processo di incubazione per la creazione di imprese vitali. Il caso del Consorzio ARCA
2013
Obiettivi . Il processo di creazione di nuove imprese risulta particolarmente complesso qualora parta da idee altamente innovative che trovano difficolta ad essere percepite come valide dai sovra sistemi. Obiettivo del presente lavoro e dimostrare che gli incubatori accademici svolgono un ruolo determinante per la vitalita di queste imprese. Metodologia . Attraverso un caso studio contraddistinto da un embedded design si analizza l’efficacia del processo di incubazione degli spin-off dell’incubatore del Consorzio Arca. Risultati . L’efficacia del processo di incubazione e dimostrata dall’elevato numero di spin-off che, al termine del periodo di incubazione, sono capaci di competere con succ…
The airway response to deep inspirations decreases with COPD severity and is associated with airway distensibility assessed by computed tomography.
2008
In patients with mild chronic obstructive pulmonary disease (COPD), the effect of deep inspirations (DIs) to reverse methacholine-induced bronchoconstriction is largely attenuated. In this study, we tested the hypothesis that the effectiveness of DI is reduced with increasing disease severity and that this is associated with a reduction in the ability of DI to distend the airways. Fifteen subjects [Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage I–II: n = 7; GOLD stage III–IV: n = 8] underwent methacholine bronchoprovocation in the absence of DI, followed by DI. The effectiveness of DI was assessed by their ability to improve inspiratory vital capacity and forced expira…
A study to evaluate the lifestyle of medical students in Palermo (Italy) [Indagine sugli stili di vita degli studenti della Facoltà di Medicina di Pa…
2008
Scientific evidence confirms that unhealthy life habits play an important role in the development of many disorders in all age groups. This study evaluated the lifestyles of 445 first-year medical students in Palermo and Caltanissetta (Italy) by using an anonymous self-administered multiple choice questionnaire Approximately 97% of participants believe that a healthy diet is either "very important" or "extremely important" but only 44% follow a healthy diet. Fifty eight percent frequently perform sports/physical activities while eight percent report being sedentary. A peak in alcohol consumption was found to generally occur in one single day of the week. Twelve percent of those interviewed …
Qualità della vita, benessere e adattamento in studenti stranieri. Un'indagine esplorativa
2010
Il presente contributo riporta le prime rilevazioni di una ricerca esplorativa sulla qualità delle relazioni umane di 15 studenti stranienri iscritti ai corsi di laurea dell’Università degli Studi di Palermo. Di particolare interesse sono state la comprendione delle motivazioni e dei vissuti emotivi legati al trasferimento, l’adattamento ai nuovi ambienti di vita e il confronto con la differenza culturale. Nello specifico sono stati indagati i livelli di soddisfazione e benessere percepito, il legame affettivo verso i luoghi e la rappresentazione di sé e del vissuto emozionale.
Precursors of Body Dissatisfaction and its Implication for Psychological Well-Being in Young Adults
2019
The authors examined leisure-time physical activity (LTPA), body mass index (BMI), and perceived physical ability as body dissatisfaction antecedents, and analyzed their relationship to well-being. The sample comprised 501 university students. Data were collected using a self-administered survey. Path analysis revealed that LTPA positively predicted perceived physical ability. BMI and perceived physical ability predicted body dissatisfaction (positively and negatively, respectively). Body dissatisfaction negatively predicted subjective vitality, whereas perceived physical ability positively predicted subjective vitality. These results support the inclusion of LTPA in intervention programs t…
EFICACIA DE UN PROGRAMA DE INTERVENCIÓN PARA MEJORAR LA COMPETENCIA, AUTONOMÍA Y BIENESTAR DE EDUCADORES DE CENTROS DE PROTECCIÓN DE MENORES
2010
En este estudio cuasi-experimental pre-test post-test sin grupo control, se analizaron los efectos de un programa de intervencion, cuyo objetivo fue mejorar el bienestar de los educadores a traves de la satisfaccion de las necesidades de competencia y de autonomia. Participaron 55 educadores, 24 hombres y 31 mujeres (M edad = 33,6; DT = 8,1) que trabajaban en Centros de Proteccion de Menores de la Comunidad Valenciana. Los resultados mostraron un cambio significativo en todas las variables en la direccion esperada. Ademas, informaron que los cambios en la satisfaccion de las necesidades de competencia y autonomia produjeron cambios en la autoestima; mientras que las variaciones en la vitali…

SUCESOS VITALES Y TENSIONES EN FAMILIAS CON HIJOS ADOLESCENTES: Life events and strains in families with teenagers
2001
Los objetivos de este estudio son: a) Describir los sucesos vitales y tensiones que afectan a los padres con hijos adolescentes, y b) Verificar las posibles diferencias en la descripción de estos sucesos por parte de los padres en función de la edad del hijo adolescente mayor: mayor o menor de 19 años. A tal fin, una muestra de 386 padres (193 matrimonios) de hijos adolescentes fueron evaluados a partir del FILE (Hernández Córdoba 1991). Resultados: a) durante el último año se da un mayor promedio de tensiones intrafamiliares, seguidas por las económicas y laborales; b) los padres con un hijo primogénito de 19 años o más experimentan más tensiones por enfermedad, y por la entrada o salida d…
Cardiovascular and respiratory variability during orthostatic and mental stress: A comparison of entropy estimators
2017
The aim of this study is to characterize cardiovascular and respiratory signals during orthostatic and mental stress as reflected in indices of entropy and complexity, providing a comparison between the performance of different estimators. To this end, the heart rate variability, systolic blood pressure, diastolic blood pressure and respiration time series were extracted from the recordings of 61 healthy volunteers undergoing a protocol consisting of supine rest, head-up tilt test and mental arithmetic task. The analysis was performed in the information domain using measures of entropy and conditional entropy, estimated through model-based (linear) and model-free (binning, nearest neighbor)…
Information-theoretic assessment of cardiovascular variability during postural and mental stress
2016
This study was aimed at investigating the individual and combined effects of postural and mental stress on short-term cardiovascular regulation. To this end, we applied measures taken from the emerging framework of information dynamics on the beat-to-beat spontaneous variability of RR interval and systolic arterial pressure (SAP) measured from healthy subjects in the resting supine position and during the separate and simultaneous execution of experimental protocols performing head-up tilt (HUT) and mental arithmetics (MA). The information stored in RR interval variability, a measure inversely related to the complexity of the time series, increased significantly during HUT and HUT+MA compar…
