Il dinamismo e la competitività delle imprese italiane: le high-growth enterprises e le gazzelle familiari e non familiari.
2019
A high percentage of businesses comes to an end shortly after birth. This highly vulnerable condition is a hallmark of young businesses, as early stage survival rates are low in all countries and industries. This paper recalls the main causes of vulnerability of companies in their start-up phase, whose knowledge is useful to prevent their manifestation and, in this way, to encourage the creation of companies more likely to overcome the difficult first stage of life. To promote economic development, however, it is not enough to create businesses, they have to last over time. To identify the characteristics that businesses – and therefore also young ones – must possess in order to survive and…
The Usefulness of Optical Coherence Tomography in Disease Progression Monitoring in Younger Patients with Relapsing-Remitting Multiple Sclerosis: A S…
2022
The purpose of the study was to assess the usefulness of optical coherence tomography (OCT) in the detection of the neurodegenerative process in younger patients with multiple sclerosis (MS). The study group consisted of 61 patients with a relapsing remitting course of MS (mean age 36.4 ± 6.7 years) divided into two groups: short (≤5 years) and long (>10 years) disease duration. OCT, P300 evoked potential, Montreal Cognitive Assessment, and performance subtests (Picture Completion and Digit Symbol) of the Wechsler Adult Intelligence Scale were performed in all patients. Mean values of most parameters assessed in OCT (pRNFL Total, pRNFL Inferior, pRNFL Superior, pRNFL Temporalis, mRNFL, G…
The spatial dimension of the French private rental markets: Evidence from microgeographic data in 2015
2021
International audience; This article draws on data collected by local rental observatories in 12 French urban units in 2015 to analyze the spatial dimension of hedonic rental prices in the private rental market through (i) the spatial heterogeneity between urban units and (ii) the wide variety of contextual and locational characteristics (socio-economic, environmental (dis)amenity, and accessibility) and flexible specifications to capture their potential non-linear influence on rent. Based on a joint test of equality of coefficients across all urban units, we find that hedonic prices differ for 75% of the characteristics, thereby justifying a detailed analysis of heterogeneity.

2015
Spanish Abstract: El objetivo de este trabajo es analizar la relacion que existe entre la rentabilidad economica de las empresas manufactureras y la integracion vertical, asi como conocer cuales son las caracteristicas que determinan que una empresa tome la decision de integrarse verticalmente. De los resultados obtenidos podemos destacar los siguientes aspectos: en primer lugar, la integracion vertical de las empresas de la industria agroalimentaria es determinante de la rentabilidad economica y; en segundo lugar, tambien hemos comprobado la existencia de una relacion directa entre la integracion vertical y la especificidad, mostrando que las empresas con productos y activos mas especifico…
Positive Youth Development in Bulgaria, Italy, Norway and Romania: Testing the Factorial Structure and Measurement Invariance of the 5Cs Model
2021
This chapter applies the 5Cs model of PYD comprising competence, confidence, character, connection and caring among 1403 youth (M = 18.91 years) in Bulgaria (n = 196), Italy (n = 354), Norway (n = 564) and Romania (n = 289). These countries offer a novel and unique context to apply PYD as related comparative work with youth samples is rare across Eastern (Bulgaria and Romania), Southern (Italy) and Northern Europe (Norway). Further, Bulgaria and Romania are emerging nations following the collapse of the communism in late 1980s in contrast to Italy being a traditionally patriarchal country and social equity driven Norway. The chapter presents an empirical example that evaluates the factorial…

The measurement of coping in achievement situations: an international comparison
2001
Abstract English and German versions of a newly developed instrument for measuring coping with achievement stressors (the Mainz Coping Inventory — Ego Threat; MCI-E) were presented to samples of American and German students. Equivalence of the two versions was determined by principal component and confirmatory factor analysis (CFA). The CFA included a multiple group analysis. This analysis was employed to compare factor patterns, loadings, factor variances and covariances across the two samples. In addition, relationships between the coping instrument and tests which are already established in English and German versions (among others, the NEO Five Factors Inventory, the State-Trait Persona…
Yield and Fruit Quality Characterization of Eight Old Sicilian Apple Cultivars
2011
In this trial, we examined the quality of eight old Sicilian apple cultivars (‘Cannamelo’, ‘Cardinale’, ‘Gelata Cola’, ‘Gelata’, ‘Granatino’, ‘San Giuseppe’, ‘Virticchiaro’, ‘Zitella’) and a commercial one (‘Annurca’ traditional clone) through bio-agronomic performances and chemical-physical analyses. We also analyzed flowering time, ripening time, pomological characteristics, and generated a specific descriptor list that indicates a great variability among the cultivars. The data obtained showed interesting characteristics in ‘Granatino’, ‘Virticchiaro’, and ‘Zitella’, such as total soluble solid, fruit size, peel cover color, yield efficiency, and crop load.

Psychometric Properties of a Short Measure for Psychosocial Factors and Associations With Phase of Physical Activity Change Among Finnish Working-Age…
2017
Insufficient physical activity (PA) and poor physical fitness are risks for several noncommunicable diseases among working-aged men. PA programs have been launched to increase activity levels in the population but working-aged men have been underrepresented in these programs. The aim of the present cross-sectional study was to evaluate validity of a short scale for psychosocial factors among Finnish working-aged men who participated in a PA campaign. The study examined also the associations between psychosocial factors and phase of PA change across fitness groups. Physical fitness was assessed with a body fitness index constructed on the basis of a handgrip test, the Polar OwnIndex Test, a…
