Effects of the Italian financial crisis on the photovoltaic dissemination in a southern city

2013

Abstract The aim of this paper is to estimate how the profitability of grid-connected PV (photovoltaic) systems may vary month by month due to the changes in all parameters involved in the economic evaluation (discount rate, PV electricity selling price, inflation rate, price of PV devices etc.). The effects of these variations were investigated for a district of a city in the South Italy (Palermo). The results of the analysis provided the trend of the actual coverage of the district power demand from June 2010 to August 2012. In particular the load match index, which considers the daily energy demand covered by PV systems, ranged from almost 30% to less than 12%, which is less than the val…

Riflettere in gruppo come pratica emancipativa

2021

Un percorso di consapevolezza legato ad una pratica auto-osservativa e autoriflessiva all’interno del proprio contesto di lavoro è di grande importanza per la formazione personale e per un apprendimento organizzativo; implica infatti, la comprensione dei processi cognitivi individuali, organizzativi o istituzionali in cui si è immersi e costituisce uno spazio indispensabile perchè avvengano degli “apprendimenti di secondo livello”. Ciò comporta lavorare sul piano dei significati, non solo con quelli espliciti propri e altrui, ma anche con le premesse che danno origine a prassi comuni e condivise . Fondamentale in questo senso è la dimensione di gruppo perché consente di adottare una logica …

The 1-way on-line coupled atmospheric chemistry model system MECO(n) – Part 3: Meteorological evaluation of the on-line coupled system

2012

Abstract. Three detailed meteorological case studies are conducted with the global and regional atmospheric chemistry model system ECHAM5/MESSy(→COSMO/MESSy)n, shortly named MECO(n), in order to assess the general performance of the on-line coupling of the regional model COSMO to the global model ECHAM5. The cases are characterised by intense weather systems in Central Europe: an intense cold frontal passage in March 2010, a convective frontal event in July 2007, and the high impact winter storm "Kyrill" in January 2007. Simulations are performed with the new on-line-coupled model system and compared to classical, off-line COSMO hindcast simulations driven by ECMWF analyses. Precipitation o…

Free-surface flows solved by means of SPH schemes with numerical diffusive terms

2010

A novel system of equations has been defined which contains diffusive terms in both the continuity and energy equations and, at the leading order, coincides with a standard weakly-compressible SPH scheme with artificial viscosity. A proper state equation is used to associate the internal energy variation to the pressure field and to increase the speed of sound when strong deformations/compressions of the fluid occur. The increase of the sound speed is associated to the shortening of the time integration step and, therefore, allows a larger accuracy during both breaking and impact events. Moreover, the diffusive terms allows reducing the high frequency numerical acoustic noise and smoothing …

Impact evaluation of reactive assessment strategies to address social loafing by promoting student cooperation and encouraging mutual support

2013

Cooperative work is an effective strategy when team members are kept motivated and collaborate towards the achievement of a common goal. However, social loafing may significantly reduce educational gains. In this article, we analyse whether assessment-based reactive strategies that exploit existing emotional relationships between the team members are effective as a response to unequal commitment in cooperative tasks. In particular, an adaptive negotiation process that permits students to improve their grades by improving future scores obtained by free riders is suggested. Findings support that these types of strategies may have a great impact in fostering peer tutoring, student cooperation …

Social comparison, coping and depression in people with spinal cord injury

2006

The present study among 70 people with spinal cord injury examined the prevalence and correlates of identification (seeing others as a potential future) and contrast (seeing others in competitive terms) in social comparison as related to coping and depression. The most prevalent social comparison strategy was downward contrast (a positive response to seeing others who were worse-off), followed by upward identification (a positive response to perceiving better-off others as a potential future), downward identification (a negative response to perceiving worse-off others as a potential future), and upward contrast (a negative response to seeing others who were better-off). Those with less seve…

Diagnóstico etilógico de la disfunción ventricular izquierda con tomografia computerizada: comparación con coronariografía y cardiorresonancia

2012

[EN] Introduction and objectives To evaluate the capability of multidetector computed tomography to diagnose the coronary etiology of left ventricular dysfunction compared with using invasive coronary angiography and magnetic resonance. Methods Forty consecutive patients with left ventricular dysfunction of uncertain etiology underwent invasive coronary angiography and contrast magnetic resonance. All patients were evaluated with multidetector computed tomography including coronary calcium presence and score, noninvasive coronary angiography, and myocardial tissue assessment. Results The sensitivity and specificity of the presence of coronary calcium to identify left ventricular dysfunction…

Reproducible research practices, openness and transparency in health economic evaluations: study protocol for a cross-sectional comparative analysis

2020

INTRODUCTION: There has been a growing awareness of the need for rigorously and transparent reported health research, to ensure the reproducibility of studies by future researchers. Health economic evaluations, the comparative analysis of alternative interventions in terms of their costs and consequences, have been promoted as an important tool to inform decision-making. The objective of this study will be to investigate the extent to which articles of economic evaluations of healthcare interventions indexed in MEDLINE incorporate research practices that promote transparency, openness and reproducibility. METHODS AND ANALYSIS: This is the study protocol for a cross-sectional comparative ana…

Customer-oriented counseling for physical activity in older people: study protocol and selected baseline results of a randomized-controlled trial (IS…

2007

The objective of this study is to describe the rationale, design and selected baseline results of a 2-year randomized-controlled trial (RCT) on the effects of physical activity counseling in community-living older people. After a four-phase screening and data-collection process targeting all independently living people in the city center of Jyvaskyla, Finland, six hundred and thirty-two 75–81-year-old cognitively intact, sedentary persons who were able to move independently outdoors at least minimally and willing to take part in the RCT were randomized into intervention and control groups. At baseline, over half of the subjects exercised less than two to three times a month and two-thirds w…
