CO2LD: An innovation educational project for High Degree Professional Training in Refrigeration

2013

EN] Refrigeration is one of the technology sectors that has sufered the most changes in the last twenty years, because of the negative impact of the fuids used in the refrigeration cycles, i.e., refrigerants, due to their impact on the ozone layer and their contribution to global warming. As a result of their negative efects, the European Union has established several directives to restrict the use of refrigerant fuids, and the sector therefore needs to adapt to the new regulations. This process of adaptation of the refrigeration sector to the new regulations must be carried out by all the agents involved, including those engaged in the training and education of the future refrigeration tec…

The comprehensive aerospace index (CASI): Tracking the economic performance of the aerospace industry

2008

In this paper, we described the Comprehensive Aerospace Index (CASI), a financial index aimed at representing the economic performance of the aerospace industry. CASI is build upon a data set of approximately 20 years of daily close prices set, from January 1987 to June 2007, from a comprehensive sample of leading aerospace-related companies with stocks negotiated on the New York Exchange (NYSE) and on the over-the-counter (OTC) markets. We also introduced the sub-indices CASI-AERO, for aeronautical segment, and CASI-SAT for satellite segment. and considered the relation between them. These three indices are compared to others aerospace indices and to more traditional general financial indi…

The Luenberger productivity indicator in the water industry: An empirical analysis for England and Wales

2014

Abstract We innovate in the field of water companies' performance with an application of the directional distance function and the Luenberger productivity indicator (LPI) to the assessment of water companies' productivity growth. The advantage of our approach is that it takes into account both input contractions and output expansions. The analysis covered 22 water companies from England and Wales using data over the period 2001–2008. To the best of our knowledge, there are no prior studies applying the Luenberger productivity indicator to the water industry in England and Wales or other countries. For the sake of comparison, the traditional Malmquist productivity index (MPI) was also estima…

The New Nino Capability Index for Dynamic Process Capability Analysis

2013

The process capability analysis is a crucial activity to evaluate if the process outcome meets the design specifications. Classically, such analysis is performed by verifying the in-control condition of the process and evaluating suitable capability indices, by assuming the process in-control steady-state condition. However, the in-control period of the process characterizes only a part of the system functioning cycle, the one with the lower defective rate. In particular, the system functioning cycle is also characterized by the out-of-control period, during which a greater defective rate is produced, and such increasing is not considered by the widely adopted capability indices. As consequ…

Success factors for information technology supported international technology transfer: Finding expert consensus

2006

Information technology (IT)-supported international technology transfer (ITT) is complex, risky, and fails often. No empirical studies are available on the factors that affect the success of IT-supported ITT. We review applicable theories (i.e. diffusion of innovation theory) and empirical research in conventional technology transfer to develop such a model. We carry out a multiple focus group method to rank factors that affect the success of IT-supported ITT and then apply a branch and bound method to derive a consensus ranking of these factors. The identified consensus ranking sheds light on factors that are similar to those of DOI theory and suggests a pattern of factors that affect IT-s…

A model of goal dynamics in technology-based organizations

2011

The purpose of the present work is to build a suitable system dynamics model for goal dynamics in organizations, as proposed by Barlas and Yasarcan (2008). The proposed model does not bear any ambition of being exhaustive: the main objective of this paper is to propose a model of goal dynamics in which Goal Setting, Management by Objectives and Training are viewed as human resource practices able to enhance workers' goal commitment, and therefore, improve organizational performance. In the first part of this paper, an analysis of the Goal Setting Theory and the role of goal setting practices, in bettering worker's performance, are stressed. In the second part, a case-study, the causal loop …

Workforce active ageing case study in a Romanian manufacturing company

2017

Ageing workforce is a major trend that characterizes the demographic evolution of Europe, which generally affects the society, but also the organizations from economic and social point of view. Employers should change their negative perceptions of ageing workforce, whereas the changes that occur along with ageing are unable to influence the efficiency of work, assuming that a suitable strategy implemented to prevent and manage potential problems. The paper includes European and national statistics on the issue, a case study analysing the workforce ageing management in a Romanian manufacturing company, which has succeeded in achieving the active ageing target, and - on this basis - several g…

Planning Rehabilitation Actions on Water Distribution Networks in Condition of Data Scarcity

2011

The paper shows a viable approach to the selection of water networks rehabilitation actions, in condition of data scarcity and uncertainty, based on the use of four concise performance literature indices, allowing the analysis and identification of efficient, reliable and robust rehabilitation alternatives, even if assessed on the basis of a relatively small amount of data. A promising statistical sampling method of water consumptions is also described, that may be fruitfully employed within the proposed approach for drafting water balances at network district scale in order to quantify the extent of leakages. The illustrated case study shows that the selected indices are capable to describ…
