Do microfinance institutions benefit from integrating financial and nonfinancial services?
2017
This article examines the impact of microfinance ‘plus’ (i.e. coordinated combination of financial and nonfinancial services) on the performance of microfinance institutions (MFIs). Using a global data set of MFIs in 77 countries, we find that the provision of nonfinancial services does not harm nor improve MFIs’ financial sustainability and efficiency. The results however suggest that the provision of social services is associated with improved loan quality and greater depth of outreach.
Nanofilm metal layers as vacuum quality sensors
2010
Abstract A monitoring device for vacuum quality is realized by lowest cost single use oxygen sensors for vacuum insulation panels. They use the pressure dependence of oxide layer growth thickness on electrically measured metal nanofilms. These films were manufactured by e-beam evaporation, characterized in terms of resistance change with subsequent modeling of underlying mechanisms.
SAFETY COVER HYDRO-PV Dispositivo domotico multifuzione per la manutenzione e la sicurezza dei pannelli fotovoltaici con aumento dell’efficienza e de…
2018
Con l’aumento dell’uso dell’energia solare, sia in ambito civile che in ambito industriale, diventa sempre più importante il problema della manutenzione e della gestione dei pannelli fotovoltaici.Il dispositivo Safety Cover Hydro - PV, ideato e brevettato dai membri dalla Safety Environmental Engineering (spin-off dell’Università degli Studi di Palermo che opera nell’ambito della Sicurezza Ambientale) consente di superare tali limiti
Impact of Novel Energy Management Actions on Household Appliances for Money Savings and CO2 Emissions Reduction
2009
In order to obtain CO2 emissions reductions, energy management control actions inside apartments and detached houses have to be carried out. In this work, new control actions devoted to the reduction of electrical energy consumptions inside typical Italian apartments are proposed. These “Distributed on Site” (DoS) actions consist in employing specific control strategies to smartly exploit the hot water provided by a solar panel, the electricity generated by a photovoltaic panel and the delayed starting of appliances.
Is the sustainability profile of FinTech companies a key driver of their value?
2022
[EN] The digitisation process is affecting all markets and raising consumer awareness about companies' sustainable behaviour. This work studies the effect of the sustainability profile of FinTech companies on the firm (market value and book value) as the factors that add value to investors and motivate their evolution in markets are still unknown. Using the KBW and Nasdaq FinTech Indices, and the NASDAQ Insurance Index (IXIS), we composed a panel of 95 companies over a 10-year period (2010-2019) with economic-financial variables and data about green certificates and sustainability indices. The applied methodology is based on dynamic (GMM-SYS) and static (PCSE) panel data models. Our results…
Assessment of the Operating Temperature of Crystalline PV Modules Based on Real Use Conditions
2014
Determining the operating temperatureTcof photovoltaic panelsPVis important in evaluating the actual performance of these systems. In the literature, different correlations exist, in either explicit or implicit forms, which often do not account for the electrical behaviour of panels; in this way, estimatingTcis based only on the passive behaviour of thePV. In this paper, the authors propose a new implicit correlation that takes into account the standard weather variables and the electricity production regimes of aPVpanel in terms of the proximity to the maximum power points. To validate its reliability, the new correlation was tested on two different PV panels (Sanyo and Kyocera panels) and…
Panel Discussion: Systems for Data Analysis What they AEE; what they Could be?
1985
CRANE: I’d like to pose a couple of questions: (1) Command Languages — A tool for the astronomer or for the programmer? (2) Portability — Holy Cow or Red Herring? I propose that we start with the first one and see how far we get. If we don’t get past that, fine. If we get on to the question of portability, this is also fine. Let me just open up the discussion by asking Rudi Albrecht to make a comment.
Hysteresis vs. natural rate of unemployment: new evidence for OECD countries
2004
Abstract The paper tests hysteresis effects in unemployment using panel data for 19 OECD countries. We apply a sequential procedure based in two multivariate augmented Dickey-Fuller test (ADF)-type panel unit root tests in a SURE framework. We strongly reject the joint null of hysteresis and find that only seven countries present evidence of hysteresis.
Selection Correction in Panel Data Models: An Application to Labour Supply and Wages
2000
In recent years a number of panel estimators have been suggested for sample selection models, where both the selection equation and the equation of interest contain individual effects which are correlated with the explanatory variables. We review and compare some of these estimators, and apply them to estimating the return to actual labour market experience for females, using a panel of twelve years. All these estimators rely on the assumption of strict exogeneity of regressors in the equation of interest, conditional on individual specific effects and the selection mechanism. This assumption is likely to be violated in many applications. Also, life history variables are often measured with…
Dynamic Behaviour of an Axially Moving Plate Undergoing Small Cylindrical Deformation Submerged in Axially Flowing Ideal Fluid
2011
Abstract The out-of-plane dynamic response of a moving plate, travelling between two rollers at a constant velocity, is studied, taking into account the mutual interaction between the vibrating plate and the surrounding, axially flowing ideal fluid. Transverse displacement of the plate (assumed cylindrical) is described by an integro-differential equation that includes a local inertia term, Coriolis and centrifugal forces, the aerodynamic reaction of the external medium, the vertical projection of membrane tension, the bending resistance, and external perturbation forces. In the two-dimensional model thus set up, the aerodynamic reaction is found analytically as a functional of the cylindri…
