Optical Link Card Design for the Phase II Upgrade of TileCal Experiment

2011

This paper presents the design of an optical link card developed in the frame of the R&D activities for the phase 2 upgrade of the TileCal experiment. This board, that is part of the evaluation of different technologies for the final choice in the next years, is designed as a mezzanine that can work independently or be plugged in the optical multiplexer board of the TileCal backend electronics. It includes two SNAP 12 optical connectors able to transmit and receive up to 75 Gb/s and one SFP optical connector for lower speeds and compatibility with existing hardware as the read out driver. All processing is done in a Stratix II GX field-programmable gate array (FPGA). Details are given on th…

A Cautionary Note on Incremental Fit Indices Reported by LISREL

2005

Abstract. Incremental fit indices (IFIs) are regularly used when assessing the fit of structural equation models. IFIs are based on the comparison of the fit of a target model with that of a null model. For maximum-likelihood estimation, IFIs are usually computed by using the χ2 statistics of the maximum-likelihood fitting function (ML-χ2). However, LISREL recently changed the computation of IFIs. Since version 8.52, IFIs reported by LISREL are based on the χ2 statistics of the reweighted least squares fitting function (RLS-χ2). Although both functions lead to the same maximum-likelihood parameter estimates, the two χ2 statistics reach different values. Because these differences are especi…

Psychometric properties of the Spanish Burnout Inventory among staff nurses

2015

Accessible summary The burnout syndrome contributes to the deterioration in the quality of personal life as well as lower quality practice in healthcare personnel. Researchers have been concerned about the psychometric limitations of some previous questionnaires designed to evaluate burnout. The Spanish Burnout Inventory was developed to address the problems associated with other instruments, but it has not yet been validated in staff nurses. This study provides evidence that the Spanish Burnout Inventory has adequate psychometric properties to estimate burnout in staff nurses. The Spanish Burnout Inventory offers a theoretical proposal to explain the different components of burnout. The Sp…

Upstream Product Market Regulations, ICT, R&D and Productivity

2017

Our study aims to assess the actual importance of the two main channels via which upstream anti-competitive sector regulations are usually considered to impact productivity growth, i.e. by acting as a disincentive to business investments in R&D and in ICT. We estimate the specific impacts of these two channels and their shares in the total impact as opposed to alternative channels of investments in other forms of intangible capital that we cannot explicitly consider for lack of appropriate data such as improvements in skills, management and organization. To achieve this, we specify an extended production function explicitly relating productivity to R&D and ICT capital as well as to upstream…

Open Innovation practices on firm performance: evidences from biotech industry

2012

The research presented in this paper explores the effect of Open Innovation (OI) on firm performance in the biotech-pharma industry sector. Specifically, although existing researches on OI effectiveness have separately investigated the effect of OI practices on innovation and financial performance, this study evaluates the concurrent effect of all those practices on both such performance dimensions in a single framework. We claim the importance for a manager to explore concurrently the influence of specific OI practices both on innovation and economic-financial performance. We empirically test our framework on a sample of 120 companies listed on NASDAQ Biotechnology Index.

Opportunities and pitfalls related to e-commerce strategies in small-medium firms: A system dynamics approach

2002

E-commerce is often perceived as a powerful lever to foster growth of SMEs. However, both the literature and empirical evidence have shown the perils hidden in superficial decision making by SME entrepreneurs. A system dynamics (SD) approach is used in this article to demonstrate how managing processes of accumulation and depletion of strategic assets, detecting inertial effects of decisions made in the past, and selectively acting on policy levers are likely to help entrepreneurs in understanding opportunities and pitfalls related to e-commerce strategies. A feedback analysis of three case studies selected from the literature and the main findings from a survey conducted by the authors on …

Validierung der Messung gesundheitsbezogener Lebensqualität mittels des Short-Form-Health-Survey-12 (SF-12 Version 2.0) in einer deutschen Normstichp…

Validation of the Short-Form-Health-Survey-12 (SF-12 Version 2.0) assessing health-related quality of life in a normative German sample Objectives: Convergent and divergent validation of the Short-Form-Health-Survey-12 assessing HRQoL by analyzing its associations with depressiveness (PHQ-9), social support (OSS-3) and satisfaction with life (SWLS). Methods: A normative German sample (N = 2.524) was analyzed using correlation, regression as well as confirmatory factor analysis and structural equation modelling for ordinal data. Results: The SF-12-scale Mental Health is associated most strongly with the validation criteria (PHQ: r[scales/constructs] = -.73/-.88, OSS-3: r = .35/.55, SWLS: r =…
