Nowadays, customers purchase habits have changed: they do not buy more goods or services in the traditional sense, perceiving them as two separated entities. They rather look for a solution, whose value encompasses many intertwined components, some of them being services and some being goods. In this context, the Product-Service System (PSS) concept finds its root. The servitization process of a product manufacturer into a provider of a PSS still constitutes a major managerial challenge. This challenge is based on a new kind of solution, which considers the continuum between services and products, where services represent a key element for gaining competitiveness. Theoretical and practical experiences show that servitization pushes organisations to change their strategies, operations and value chain, technologies, people expertise and system integration capabilities. As a consequence, different competences are requested to be analysed to have a complete vision of the PSS phenomenon. An international interdisciplinary working group is important to fulfil the need to provide a complete vision of the PSS. Due to the vastness of the area, it is relevant to bring together, in the context of a collaborative scheme of research exchanges, the reciprocal knowledge of the partners. The project proposal links 10 members: 4 EU, 2 AC, and 4 third country partners, which have agreed for a common exchange program on the analysis of the Product-Service System across Life Cycle. The exchange program aims to facilitate the deployment of a collaborative scheme focused on the exchange of the knowledge required to develop new models/methods/ICT tools to support the PSS across all its Life Cycle phases. Each member provides complementary knowledge on the field. The project will concern the exchange of a set of various activities of PhD students, researchers and professors. The planned exchange scheme will enable the reciprocal transfer of knowledge between the members.

This article discusses recent scientific research performed by the author in understanding the composition of archaeological purple pigments and dyes from molluskan sources, which were primarily used for the dyeing of royal and priestly textiles, as also cited in the Bible. Towards this end, the high-performance liquid chromatography (HPLC) method has been applied to the qualitative and quantitative multi-component fingerprinting of purple pigments extracted from various Muricidae mollusks inhabiting the Mediterranean waters. The results show that the colorants in these purple pigments belong to three chemical groups: the indigoids (of major importance), the indirubinoids, and the isatinoids. Application of this analytical method to purple pigments and dyes on archaeological artifacts from the ancient Near and Middle East has lead to a number of breakthroughs and discoveries made by this laboratory. These include the following: decipherment of the optimal method by which the ancients practiced purple-dyeing by completely natural means; first HPLC analysis of a raw unprocessed purple archaeological snail pigment and the resulting identification of a dibrominated indirubin in this pigment; discovery of the purple pigment as the sole paint pigment on a 2,500 royal marble jar from the Persian King Darius I; and the discovery that a 2,000 year old miniscule fabric found atop the Judean Desert palatial fortress of Masada belonged to the royal purple mantle of King Herod I and is the first Biblical Argaman dye found in ancient Israel. © 2012 Materials Research Society.

Steady and unsteady mass transfer in the continuous phase around slightly deformed oblate spheroidal drops at low (but not zero) Reynolds numbers was investigated theoretically. Asymptotic analytical solutions for short and long times, at large Peclet numbers, were obtained by the useful equations derived by Lochiel and Calderbank and by Favelukis and Mudunuri for axisymmetric drops of revolution, with the only requirements being the shape of the drop and the tangential velocity at the surface of the drop. As expected, the result, although complicated, represents a small correction to the classical problem of mass transfer around a spherical drop under creeping flow conditions, since the physical problem presented here requires both the Reynolds and the Weber number to be much smaller than one. © 2010 Elsevier Ltd.

The transfer of mass between a slender drop and a liquid in an axisymmetric extensional flow, at zero Peclet numbers, is theoretically studied. We allow the external flow to have a small (but not zero) amount of inertia. The problem is governed by three dimensionless parameters: the capillary number (Ca. >>. 1), the viscosity ratio (λ <<. 1) and the external Reynolds number (Re. <<. 1). It is shown that the shape of the drop is, at first approximation, a slender spindle suggesting the usage of the bispherical coordinate system. Applying the method presented by Szegö and Pyne, for the electrostatic capacity of a spindle, an analytical solution containing conal functions is obtained. The results show that, as the capillary number or the Reynolds number increase, the drop becomes thinner and longer, the surface area increases, resulting in larger mass transfer rates, with the capillary number being the most influential parameter. © 2015 Elsevier B.V.

The major indigoids constituting modern and archaeological purple pigments produced from molluskan species include, in varying compositions, indigo, 6-bromoindigo, and 6,6′-dibromoindigo. Though woolen Tyrian Purple dyeings produced from these pigments were the most prized and precious of all dyeings in antiquity, a full chromatographic and colorimetric analysis of multi-fibered textiles dyed with these indigoids has not been previously performed. This current study reports on high-performance liquid chromatographic (HPLC) analyses conducted on the indigoid pigments and on woolen dyeings individually produced from them. In addition, comparative colorimetric analyses via reflectance spectrophotometry were performed on standard multifiber fabric swatches, each consisting of 13 different synthetic and natural fibrous materials. Each swatch was dyed with one of the cited indigoids. These colorimetric properties included the Kubelka-Munk spectral curves, color strengths at the wavelengths of maximum absorptions, color coordinates of the CIE L*a*b* and L*C*h* color spaces, and the color differences. Excellent functional correlations were observed among these properties and these relationships should be applicable to similar dyeings on other fabric materials. The results show that filament triacetate and nylon-66 possess the most remarkable color strengths of all the fiber materials investigated in all the dyeings, and of the natural fibers studied, wool possessed the highest color strength and cotton the poorest with all three dyes. Such chromatographic and colorimetric analyses would further our understanding of the colors produced from ancient, and modern, purple-dyed textiles. © 2012 Elsevier Ltd. All rights reserved.

"Management by walking around" (MBWA) is a practice that has aroused much interest in management science and practice. The purpose of this study is to demonstrate adaptation of this practice to safety management. We describe a three-year long case study that collected empirical data in which a modified MBWA was practiced in order to improve safety in a semiconductor fabrication facility. The main modification involved integrating an information system with the MBWA in order to create a practice that would generate safety leadership development and an organizational safety learning mechanism, while promoting employee safety participation. The results of the case study demonstrate that the SMBWA practice facilitated thousands of tours in which safety leadership behaviors were practiced by managers and by employees (employees performed five times as many tours as managers). The information system collected information about safety behaviors and safety conditions that could not otherwise be obtained. Thus, this study presents a new organizational safety practice SMBWA, and demonstrates the ways in which SMBWA may improve safety in organizations. © 2011 Elsevier Ltd. All rights reserved.

Business Intelligence (BI) systems are applied by increasing numbers of organizations in a wide range of sectors. Despite the growing numbers of BI solutions and the experience augmented in many implementation projects worldwide, as well as the value that BI systems provide to organizations, IT literature lacks a coherent set of definitions through which BI systems can be classified, categorized, and assessed. Furthermore, BI implementation projects often do not succeed or do not fully accomplish the degrees of value and performance as expected, when firms fail to complete the system implementation, to satisfy the needs of users or when the benefits BI systems produce are lower than anticipated. This paper presents an analytical framework through which BI systems are defined and classified. On the basis of this framework, possible technical, organizational, and personal factors that affect the failure, partial or full success of BI system implementations are discussed. These factors are followed by a case study and empirical data analyses that exemplify and assess the extent to which various organizational attributes and properties of users influence the success or failure of BI implementation projects. Finally, implications regarding the management of BI system implementation projects and the organizations that apply them are derived. Copyright © 2012, IGI Global.

Ergonomics | Year: 2013
Despite the unanimity among researchers about the centrality of workplace analysis based on participatory ergonomics (PE) as a basis for preventive interventions, there is still little agreement about the necessary of a theoretical framework for providing practical guidance. In an effort to develop a conceptual PE framework, the authors, focusing on 20 studies, found five primary dimensions for characterising an analytical structure: (1) extent of workforce involvement; (2) analysis duration; (3) diversity of reporter role types; (4) scope of analysis and (5) supportive information system for analysis management. An ergonomics analysis carried out in a chemical manufacturing plant serves as a case study for evaluating the proposed framework. The study simultaneously demonstrates the five dimensions and evaluates their feasibility. The study showed that managerial leadership was fundamental to the successful implementation of the analysis; that all job holders should participate in analysing their own workplace and simplified reporting methods contributed to a desirable outcome. Practitioner summary: This paper seeks to clarify the scope of workplace ergonomics analysis by offering a theoretical and structured framework for providing practical advice and guidance. Essential to successfully implementing the analytical framework are managerial involvement, participation of all job holders and simplified reporting methods. © 2013 Copyright Taylor and Francis Group, LLC.

A photovoltaic device is presented including one or more cell units. The photovoltaic device comprises a semiconductor substrate having a patterned light collecting surface defining an array of spaced-apart substantially parallel first grooves. Each of these first grooves has a bottom portion, comprising a bottom surface and side walls extending from the bottom portion and being substantially perpendicular to the surface of the device. A heavily doped semiconductor layer in the form of spaced-apart regions is located at the bottom surfaces of the first grooves respectively. Further improvement of performance is obtained by deposition of thin metal lines on top of the heavily doped spaced apart lines.
