Uniform measure density condition and game regularity for tug-of-war games
2018
We show that a uniform measure density condition implies game regularity for all 2 < p < ∞ in a stochastic game called “tug-of-war with noise”. The proof utilizes suitable choices of strategies combined with estimates for the associated stopping times and density estimates for the sum of independent and identically distributed random vectors. peerReviewed
On (n-l)-wise and joint independence and normality of n Random variables: an example
1981
An example is given of a vector of n random variables such that any (n-1)-dimensional subvector consists of n-1 independent standard normal variables. The whole vector however is neither independent nor normal.
Bivariate Distributed Lag Models for the analysis of temperature-by-pollutant interaction effect on mortality.
2007
This paper introduces Bivariate Distributed Lags Models (BDLMs) to investigate synergic effect of temperature and airborne particles on mortality. These models seem particulary attractive since they allow to model interactions between such environmental variables accounting for possible delayed effects. A B-spline framework is used to approximate the coefficient surface of the temperature-by-pollutant interaction and possible alternatives are also discussed. A case study of mortality time-series data in Palermo, Italy, is presented to illustrate the model. Copyright © 2007 John Wiley & Sons, Ltd.
A stochastic method for robustness analysis in sorting problems
2009
ELECTRE TRI is a multiple criteria decision aiding sorting method with a history of successful real-life applications. In ELECTRE TRI, values for certain parameters have to be provided. We propose a new method, SMAA-TRI, that is based on stochastic multicriteria acceptability analysis (SMAA), for analyzing the stability of such parameters. The stability analysis can be used for deriving robust conclusions. SMAA-TRI allows ELECTRE TRI to be used with uncertain, arbitrarily distributed values for weights, the lambda cutting level, and profiles. The method consists of analyzing finite spaces of arbitrarily distributed parameter values. Monte Carlo simulation is applied in this in order to desc…

Dynamics analysis of distributed parameter system subjected to a moving oscillator with random mass, velocity and acceleration
2002
Abstract The problem of calculating the response of a distributed parameter system excited by a moving oscillator with random mass, velocity and acceleration is investigated. The system response is a stochastic process although its characteristics are assumed to be deterministic. In this paper, the distributed parameter system is assumed as a beam with Bernoulli–Euler type analytical behaviour. By adopting the Galerkin's method, a set of approximate governing equations of motion possessing time-dependent uncertain coefficients and forcing function is obtained. The statistical characteristics of the deflection of the beam are computed by using an improved perturbation approach with respect t…
A meta-analysis of distributed leadership from 2002 to 2013 : Theory development, empirical evidence and future research focus
2015
This article provides a meta-analysis of research conducted on distributed leadership from 2002 to 2013. It continues the review of distributed leadership commissioned by the English National College for School Leadership (NCSL) ( Distributed Leadership: A Desk Study, Bennett et al., 2003), which identified two gaps in the research during the 1996–2002 period. The review found that the studies had been unable to conceptualise distributed leadership or empirically outline its application. The two research gaps identified by Bennett et al. (2003) constitute the focus of the present review, which attempts to determine whether recent research has been able to fill these gaps. Based on the find…
Crowdfunding as a tool to support sustainability‐oriented initiatives: Preliminary insights into the role of product/service attributes
2019
A common goal of current research seems to uncover whether crowdfunding (CF) could be considered an effective way to support sustainability-oriented initiatives in securing funding, due to diverging results emerging from literature. We claim that the objective of proving whether CF may benefit sustainability-oriented initiatives could be misplaced; rather, we deem more fruitful to understand how critical are some attributes of products/services pursued within CF campaigns to benefiting sustainability-oriented initiatives and increasing their odds of success in CF. We focus on food-related projects as in this sector, sustainability issues apply more than to any other human activities and con…
Understanding consumer demand for sustainable beef production in rural communities
2015
In the past two decades, due to the series of crises within the agro-food system, such as BSE, dioxin, and foot and mouth disease, consumer demand for sustainable production has considerably grown in European society. Consumers seem to frame food quality in terms of social and environmental aspects of productions, which may be recognized through a certification labelling or through a system of food quality criteria that give rise to conventions of quality. The aim of our study was to understand how food quality and labelling are assessed by rural population in Southern Italy. Local beef production with sustainable voluntary certification was the focus of our empirical strategy. Our decision…
Conventions of Quality in Consumer Preference toward Local Honey in Southern Italy
2016
During the last few decades consumer demand for local foods has increased around the world, particularly in the USA and Europe. Such consumer trend also contributes to redefine a new alternative geography of food; in which local foods are perceived to be of better quality and safer. Moreover, consumers frame local food quality not only in terms of general attributes, such as taste and price, but also in terms of more subjective attributes closely linked to social and environmental aspects of products. These attributes are recognised by consumers as a range of socially constructed food quality criteria, which play an important role in the creation of information about quality and consumer de…
