A Happy Marriage: Academia, Professional and Scientific Associations
2015
This paper advocates for a greater integration between Higher education and Professional and Scientific Associations (PSAs). With the development and adoption of Information and Communication Technologies (ICTs), the costs associated with the collection, storage, processing and transmission of information have been reduced. Eventually, the supply of information has boomed. However, more does not necessarily imply better. Free online resources can enhance the learning process, but the lack of quality controls is still a major concern. Additionally, learning demands some degree of organisation and structure. We argue that Higher education can potentially benefit from a closer relationship wit…
Interactions between contingency, organizational IT factors, and ERP success
2009
PurposeThe purpose of this paper is to examine the impact of some organizational information technology (IT) factors (i.e. IT assets, employees' IT skills, IT resources, and satisfaction with legacy IT systems) and their interacting effects with two contingency factors (i.e. organization's size and structure) on enterprise resource planning (ERP) system success.Design/methodology/approachSurveys were conducted in two European countries. Respondents came from diverse, private, and industrial organizations. Relevant hypotheses were developed and tested using a structural equation modeling technique.FindingsThe analysis supported – partially or fully – six of the eight hypotheses formulated. F…
Solving the Problems of Inspection Planning under Parametric Uncertainty of Underlying Models
2013
Certain fatigued structures must be inspected in order to detect fatigue damages that would otherwise not be apparent. A technique for obtaining optimal inspection strategies is proposed for situations where it is difficult to quantify the costs associated with inspections and undetected failure. For fatigued structures for which failures (fatigue damages) are only detected at the time of inspection, it is important to be able to determine the optimal times of inspection. Fewer inspections will lead to lower fatigue reliability of the structure upon demand, and frequent inspection will lead to higher cost. When there is a fatigue reliability requirement, the problem is usually to develop an…
Organization of Production Processes through the Multi-Service Method by Performing some Identical Operations of the same Duration and Structure
2013
Organisation of production processes, by means of multi service method refers to the performance of attributions within a working system, using simultaneously or successively more inputs or more items in a single means of production, by one or more employees. In the specifically chosen case, in order to outline the advantages that shall be obtained after implementing the multi service method, we want to illustrate a situation where there are the execution conditions of certain identical operations, with the same duration and structure, in which case the running time of the performer and the means of production will be identical. Serving multiple machines finds application in all industrial …
On the improvement of monumental structure safety: a case study
2006
The present paper deals with the problem of the preservation of the monumental patrimony and discusses a practical application. The analysis methodology based on modern dynamic identification techniques was used for a monumental church in the historic area of Catania (Italy). The dynamic response of the church was measured in terms of accelerations, by means of vibration tests in situ. The numerical analyses highlighted the vulnerability of the drum dome system. Hence interest focused on this part of the building. A reduced scale model of the above system was built to be subjected to dynamic tests on a shaking table at the ENEA laboratory at Casaccia (Rome). Different kinds of reversible de…
Low-cost solutions for manipulation tasks in manufacturing systems: balancing costs and performances
2010
Abstract Industrial robots are distinguished from other types of machinery mainly on the basis of their programmability and adaptability to different tasks. However, the cost s of the state of the art solutions for every system within their structure became very high compared with some applications. This work presents two proposed solutions of so called robotic manipulators, which may fulfil some of the manipulating tasks specific to industrial robots while using low-cost solutions of transmission, actuation and automation systems.
"Towards a "fingerprint" of paper network; separating forgeries from genuine by the properties of fibre structure"
2014
A novel method is introduced for distinguishing counterfeit banknotes from genuine samples. The method is based on analyzing differences in the networks of paper fibers. The main tool is a curvelet-based algorithm for measuring the distribution of overall fiber orientation and quantifying its anisotropy. The use of a couple or more appropriate parameters makes it possible to distinguish forgeries from genuine samples as concentrated point clouds in a two- or three-dimensional parameter space. Furthermore, the techniques of making watermarks is investigated by comparing genuine and counterfeit €50 banknotes. In addition, the so-called wire markings are shown to differ significantly from each…
Structure, Effects and Deficiencies of an Entrepreneurial Ecosystem: the Spanish Case
2017
In this paper, we rely on the Spanish GEM Project to analyze the basic conditions that shape the profiles of the Spanish regional entrepreneurial ecosystem and to configure which aspects are given and which should be met in order for that ecosystem to be considered as a tool to support entrepreneurship and not just a wasteland. Although some media are incorporated, the nutrients needed for germination are not included.
A Potted History: Spain 1860–2015
2018
This chapter aims to supply a synthetic view of the historical process of economic development in Spain broken down into major stages. Rather than examine it from all angles, the text concentrates on changes involving the elements highlighted in economic theory and empirical works, that is, the rate at which the Spanish economy advanced, the evolution of its production structure and sector employment, and the degree of integration of the goods and factor markets and the effects of this in both national and supranational terms. So as to give a stylized view of the process, the analysis is carried out on the basis of four major stages into which we divide the period of study: 1860–1910, 1910–…
Heterogeneity in Family Firms
2021
This research explores in greater depth the importance of considering the heterogeneity between family businesses so as to better understand the differences in their strategic behavior, performance and business results. With this, we attempt to contribute to the theories on the relationship between corporate governance and strategic management in the field of family business research.
 Our study identifies the different configurations that may be adopted in the ownership structures and the management and governance bodies of family firms, analyzing how these configurations are related to the firm’s strategic outcomes. Using a sample of 111 family firms, we perform a cluster analysis th…
