The Use of Financial and Non-Financial Performance Measures: A Contingency Perspective

2013

Financial and non-financial index and indicators are applied in industry for measure firms’ business and operational performance. Different mix of measures are usually implemented in practice and we argue that, to a certain extent, this variability can be explained according to some contextual factors, as for instance environmental uncertainty, decentralization, type of strategic organizations and managerial practices.We develop hypothesis on the association between the usage of certain performance measures and this factors in a contingency perspective. Exploratory research based on large scale survey on manufacturing firms supports our investigation and test of the research hypothesis. R…

Rethinking the risk matrix

2011

So far risk has been mostly defined as the expected value of a loss, mathematically PL (being P the probability of an adverse event and L the loss incurred as a consequence of the adverse event). The so called risk matrix follows from such definition. This definition of risk is justified in a long term “managerial” perspective, in which it is conceivable to distribute the effects of an adverse event on a large number of subjects or a large number of recurrences. In other words, this definition is mostly justified on frequentist terms. Moreover, according to this definition, in two extreme situations (high-probability/low-consequence and low-probability/high-consequence), the estimated risk…

Enhanced TESF methodology for course excellence

2010

The need to achieve the excellence in services provided by a University has been object of study and research for several decades. Often, the focus is not only on the education service, but on several satellite services provided by a university. This article focuses on teaching, considered as a central service, believing (the authors) that the improvement actions of an academic institution should always start from this service. The work proposes the implementation of a tool able to measure student perceptions on certain selected aspects of the course. This tool is part of the Teaching Experiment and Student Feedback (TESF) methodology previously developed by the authors. Here, the steps to …

Statistical properties of a new student satisfaction index

2010

Quality of Higher Education is increasingly important in all developed countries. In fact quality and reputation are key elements to control the flow of students at national and international level. The authors have shown that quality of education can be improved through a process of self-assessment of the teaching services and a well studied analysis of the student feedback. In particular a new student satisfaction index was formulated which allows student feedback being summarised and interpreted for a continuous course improvement. In this paper some statistical properties of the student satisfaction index are illustrated, and comparisons with other measures based on Likert scales are ma…

La dimensione spaziale nella relazione tra cambiamento della popolazione e formazione di nuove imprese

2015

Questo contributo analizza la relazione tra cambiamento della popolazione e formazione di nuove imprese con particolare attenzione al ruolo dello spazio. Viene infatti, da un lato, analizzata l'influenza della concentrazione spaziale della popolazione rispetto la relazione di interesse, dall'altro, viene utilizzata una specificazione econometrica che tenga conto della correlazione spaziale presente nei dati. Lo studio condotto sulle province italiane per il periodo 2004/2007, mette in luce alcuni aspetti degni di nota. Tra questi, è di particolare interesse l'evidenza che nelle province con maggiore ritorno, in termini di natalità delle imprese, da un incremento della popolazione sono quell…

Implementation of Six Sigma in SMEs. A Case Study in Swedish Industry

2012

Many big companies today have already solid Six Sigma infrastructures. However, all over the world SMEs are only now approaching the methodology. In this presentation we expose an industrial application of a Six Sigma Black Belt project. It shows how Six Sigma was introduced and successfully implemented in a Swedish small-medium sized company. The project was carried out within the Six Sigma Black Belt course run at Chalmers University of Technology in Gothenburg. This case study is included in the book “Statistical and Managerial Techniques for Six Sigma Methodology, Theory and Application” (Wiley, 2012). The company is Structo Hydraulics AB, a manufacturing firm, located in Storfors, whic…

Statistical and managerial techniques for Six Sigma methodology. Theory and Application

Indicatori e metodi per la valutazione delle politiche territoriali: le statistiche sull’ambiente e la contabilità ambientale come strumenti per lo s…

2008

L’ingresso delle implicazioni ambientali all’interno delle logiche e delle programmazioni economiche è avvenuto quando si è compreso appieno che le risorse ambientali, pur essendo riproducibili nella loro essenza fondamentale, non seguono il concetto di riproducibilità tipico, invece, dei processi industriali, interessando cioè non una singola generazione, ma bensì più individui e più generazioni. Proprio tale considerazione è contenuta all’interno della definizione di sviluppo sostenibile che la Commissione Mondiale per l’Ambiente e lo Sviluppo ha elaborato nel 1987 (cfr. Rapporto Brundtland), specificando che i processi di sviluppo e di crescita attuali non dovevano compromettere le capac…

uality Evaluation of “Tardivo di Ciaculli” Mandarins in Post-Harvest Processing on an Industrial Scale Using a Portable Vis/NIR Device

2016

Abstract. Vis/NIR technology is widely used today to quickly and non-destructively evaluate fruit and vegetable qualities, and many applications have been found since the 1990s. However, no industrial-scale applications can further consolidate the use of non-destructive techniques in post-harvest processing. This study aims to test the possibility of applying vis/NIR technology in a modern citrus-processing plant to assess the damage that the fruits eventually suffer when they are processed on an industrial scale and the evolution of their key quality parameters in a period of 10 days after harvest. The spectral acquisitions were performed using a portable vis/NIR device, which operated in …
