The Role of Human Resource Practices and Group Norms in the Retirement Process
2009
The present study analyzed retirement intentions and behavior as part of a work role withdrawal process. We examined the influences of the organizational and group contexts in the process of work role exit by means of two sources of work role expectations: human resource practices and group norms. Three different types of human resource practices were taken into consideration: performance enhancement practices, retirement enhancement practices, and organizational pressures toward retirement. Furthermore, three types of retirement indicators were analyzed: age considering retirement for the first time, early retirement intentions, and retirement age. Hierarchical regression analyses were ca…
(Un)Routinization of the Environmental Performance Measures – A Case Study; BSC Rules but Does not Routinize
2009
This study focuses on the (un)routinization of environmental performance measures (EPMs). It studies how new environmental measures were implemented within the new environmental management system (EMS) and how they became connected with the financial measures, like cost savings and profitability. By doing so, they were connected to the taken-for-granted profit orientation of the case company in order to overcome these values and to make them succeed in organization. Later on these new measures were also included in the new BSC. In conditions of the profit oriented taken-for-granted values, the BSC locked the rule status of the environmental measures, but it locked them at the operational le…
Understanding how the strategy formation process interacts with the management of complex work
2011
PurposeThe purpose of this paper is to analyse how the strategy formation process takes place studying the relevance of the integrative perspective and the use of the variables rationality, implication and vision, and verifying the relationship between an integrative strategy formation process and the management of work and the consequences of this relationship in terms of performance.Design/methodology/approachThe paper adopted a qualitative methodology, specifically a simple case analysis, following a six‐stage process: establishing the research objectives, the theoretical research framework, unit and the level of analysis, selecting the study cases and a pilot case, and ellaborating the …
Method for improving the contouring accuracy for CNC profiling machines at the shop floor level
2009
Computer Numerically Controlled (CNC) laser cutting machines are capable of producing high-quality precise parts. However, as cutting speeds is increased, in order to achieve higher productivity, the accuracy of the parts is affected. In order to improve the contouring accuracy of these machines, a simple straight-forward joint simulation and experimental strategy is proposed. The position controllers within the feed drives are considered the key factor in improving the dynamic behavior and consequently the contouring accuracy of a CNC laser cutting machine at the shop floor level.
Defect incorporation in In-containing layers and quantum wells: Experimental analysis via deep level profiling and optical spectroscopy
2020
Abstract Recent studies demonstrated that the performance of InGaN/GaN quantum well (QW) light emitting diodes (LEDs) can be significantly improved through the insertion of an InGaN underlayer (UL). The current working hypothesis is that the presence of the UL reduces the density of non-radiative recombination centers (NRCs) in the QW itself: during the growth of the UL, surface defects are effectively buried in the UL, without propagating towards the QW region. Despite the importance of this hypothesis, the concentration profile of defects in the quantum wells of LEDs with and without the UL was never investigated in detail. This paper uses combined capacitance-voltage and steady-state pho…
Developing teachers' professional expertise through collaboration in an innovative ICT‐based learning environment
2004
Recent research emphasizes the context‐specific nature of professional knowledge and expertise, implying that developing novel practices in authentic environments is a prerequisite for teachers' professional development. The aim of this study was to find out how teachers develop their practical knowledge and expertise through shared planning and to evaluate an innovative learning project carried out in an ICT‐based environment. Two secondary school teachers of history participated in this study. The data were gathered using a multi‐methodological approach (video recordings, interviews and questionnaires). The results are described in terms of the teachers' shared experiences and their incre…

Letexte explicite la démarche et les étapes successives suivies, les modèles statistiques estiméset les difficultés méthodologi…
Biologically oriented preparation technique (BOPT) for implant-supported fixed prostheses
2017
A patient of 58 years of age without medical problems came to the clinic due to missing teeth in the upper posterior region and to change the partial fixed prosthesis in the upper anterior area. Proposed treatment: surgical phase of three conical shape tapering implants with prosthetic platform in occlusal direction with mechanize collar tissue level with fixtures to place implant-supported metal-ceramic restorations. In the anterior area, a zirconium oxide fixed partial prosthesis was vertical preparation of the tooth’s. When preparing teeth to receive fixed prostheses, the definition and shape of finish lines has been a subject of endless discussion, modification, and change ever since th…

New Interpretative Scales for Lichen Bioaccumulation Data: The Italian Proposal
2019
The interpretation of lichen bioaccumulation data is of paramount importance in environmental forensics and decision-making processes. By implementing basic ideas underlying previous interpretative scales, new dimensionless, species-independent &ldquo
