Culture and team production

2018

Abstract This paper addresses theoretically the question whether culture has an effect on economic performance in team production, and what would be an optimal team culture. The members of a team are guided both by economic incentives and by personal norms, weighed according to their prevailing level of materialism. We assume that personal norms evolve following a dynamic driven by a combination of psychological mechanisms such as consistency and conformism. The different vectors of materialism, consistency and conformism shared by the group result in a continuum of cultures characterized by different combinations of individualism and collectivism. Team culture turns out to be a fundamental…

Polyamide-Based Fibers Containing Microwave-Exfoliated Graphite Nanoplatelets

2016

Exfoliated Graphite NanoPlatelets (GNP) have been obtained from Graphite Intercalation Compounds (GIC) subjected to thermal and microwave treatments. Accurate morphological and structural characterization of obtained GNP, performed to compare the degree of exfoliation, show that microwave-treated GNP, exhibit well-exfoliated structure, without any reduction in dimensions compared with the native GIC, differently to the thermal-treated ones. Microwave-treated GNP have been introduced in polyamide (PA) through melt-mixing to obtain nanocomposite that has been subjected to elongational flow, with the aim to improve the nanofiller dispersion and induce GNP orientation along the fiber direction.…

The Transverse Crack Tension test revisited

2016

Several problems arise when measuring the mode II interlaminar fracture toughness using a Transverse Crack Tension specimen; in particular, the fracture toughness depends on the geometry of the specimen and cannot be considered a material parameter. A preliminary experimental campaign was conducted on TCTs of different sizes but no fracture toughness was measured because the TCTs failed in an unacceptable way, invalidating the tests. A comprehensive numerical and experimental investigation is conducted to identify the main causes of this behaviour and a modification of the geometry of the specimen is proposed. It is believed that the obtained results represent a significant contribution in …

Realizing the Benefits from Enterprise Information Systems: A Sociomaterial Perspective

2013

AbstractDespite the worthwhile studies that have been conducted on the realization of benefits from Enterprise Information Systems (EISs), many organizations are not satisfied with the benefits they have gained. This work draws on the sociomaterial perspective and suggests that benefits can be realized when organizations are able to utilize their capabilities in order to exploit the technological possibilities of the EISs, in addition to their willingness to change their business routines. It suggests focusing on the unintended benefits that can emerge based on the organizational capabilities and the system possibilities. The main contribution from this conceptual work is to provide a discu…

Bending test for capturing the fractional visco-elastic parameters: theoretical and experimental investigation on giant reeds

2014

In this paper attention is devoted on searching a proper model for characterizing the behavior of giant reeds. To aim at this, firstly, meticulous experimental tests have been performed in the Laboratory of structural materials of University of Palermo. Further, the novel aspect of this paper is that of using an advanced Euler-Bernoulli model to fit experimental data of bending tests. Such a model of continuum beam takes into account different constitutive laws of visco-elasticity, being real materials visco-elastic.

A systematic literature review on less common natural fibres and their biocomposites

2018

Abstract Interest in utilization of renewable resources is increasing because of public's environmental awareness and economic considerations. Lignocellulosic fibres have already attracted growing attention as reinforcement of polymeric matrices instead of synthetic ones (mainly glass) from the academic and industrial fields. In addition to kenaf, hemp, sisal, flax and jute, which are the subject of extensive investigations for composite applications since the 1970s, in the last years several researchers suggested the use of less common natural fibres, due to their low cost and availability. This paper reviews the extraction methods, chemical, morphological, thermal and mechanical propertie…

Developing business advantages from the technological possibilities of enterprise information systems

2022

Published version of an article in the journal: International journal of information systems and project management. Also available from the publisher at: http://dx.doi.org/10.12821/ijispm020203 Open Access Organizations are increasingly implementing Enterprise Information Systems (EIS), and Enterprise Resource Planning (ERP) systems in particular. Despite the notable studies on the advantages of an EIS, many organizations are not satisfied with the benefits or advantages gained. At the same time, it is assumed that such systems with increasing innovations and technological enhancements would generate abundant business advantages, if organizations exploited these opportunities. The investig…
