HUMAN CAPITAL IN GROWTH REGRESSIONS: HOW MUCH DIFFERENCE DOES DATA QUALITY MAKE?.
2000
We construct a revised version of the Barro and Lee (1996) data set for a sample of OECD countries using previously unexploited sources and following a heuristic approach to obtain plausible time profiles for attainment levels by removing sharp breaks in the data that seem to reflect changes in classification criteria. It is then shown that these revised data perform much better than the Barro and Lee (1996) or Nehru et al (1995) series in a number of growth specifications. We interpret these results as an indication that poor data quality may be behind counterintuitive findings in the recent literature on the (lack of) relationship between educational investment and growth. Using our prefe…
An academic performance indicator using flexible multi-criteria methods
2021
Composite indicators are a very useful tool for conveying summary information on the overall performance of institutions and facilitating decision-making. Increasingly, there is a demand for indicators that allow performance to be assessed after the implementation of a strategy. This has several difficulties, and in this paper, we address three of them: how to evaluate at different points in time, how to estimate the weighting of the criteria and how to normalize the data. Our proposal is based on multicriteria techniques, using a recent method, uwTOPSIS, and is applied to data collected from 2975 students enrolled in the first year of science and engineering at the Industrial University of…
An original method to compute epipoles using variable homography: application to measure emergent fibers on textile fabrics
2012
International audience; Fabric's smoothness is a key factor to determine the quality of finished textile products and has great influence on the functionality of industrial textiles and high-end textile products. With popularization of the 'zero defect' industrial concept, identifying and measuring defective material in the early stage of production is of great interest for the industry. In the current market, many systems are able to achieve automatic monitoring and control of fabric, paper, and nonwoven material during the entire production process, however online measurement of hairiness is still an open topic and highly desirable for industrial applications1. In this paper we propose a …
Optimal design of CHCP plants in the civil sector by Thermoeconomics
2007
The optimization of design and operation of trigeneration plants for civil applications is a very complex task, because of the large number of internal and external variables affecting the energetic and economic results that may be achieved. Further, energy-saving and profit-oriented optimization processes usually lead to different solutions, in terms of plant lay-out, optimal size of components and operation strategy. Thermoeconomic methodologies are very effective theoretical structures for the optimization of industrial energy-systems characterised by regular energy-demand profiles; however, they are hard to use when approaching civil applications and energy systems in unsteady operating…
Multidimensional scaling and stock location assignment in a warehouse: an application
1999
By means of an application, in the present paper, the suitability of a multivariate statistical methodology, as multidimensional scaling (MDS), to solve an optimization problem is shown. In particular, considering the stock location assignment problem in the warehouse of a supermarket chain, the solution gained by applying MDS to a set of seven variables is compared with the one obtainable by considering the usual techniques applied in this context. A wide discussion of results is reported. Copyright © 1999 John Wiley & Sons, Ltd.
A combined interval-valued ELECTRE TRI and TOPSIS approach for solving the storage location assignment problem
2019
Abstract Efficiency and effectiveness of logistic activities, in general, and of distribution networks, in particular, are largely influenced by the way warehouses operate as nodes of these networks. In recent years, warehouse management has undergone major changes due to the increase of e-commerce and competition in time-reduction. Despite that, logistic costs of warehouse processes (e.g. receiving, storage, order picking and shipping, etc.) are still often high. Referring to the order picking process, related activities may be optimized by a proper assignment of products to storage locations. In the literature, this problem is known as Storage Location Assignment Problem (SLAP). Due to th…
Learning culture and knowledge management processes: To what extent are they effectively related?
2014
In the contemporary context of high competitiveness between organizations, organizational learning culture and knowledge management (KM) have been considered key concepts in both academic and managerial settings. This study aims to provide empirical support for the relationship between organizational learning culture and knowledge management, specifically concerning the prediction of learning culture on KM processes. Data collection was carried out through questionnaires in 50 Portuguese manufacturing firms. Data was analyzed at the organizational level using standard multiple regressions. The results showed a significant and positive relationship between learning culture and KM practices. …
An entrepreneur's social capital and performance: the role of access to information in the Argentinean case
2012
Purpose - The aim of this paper is to analyze the impact of an entrepreneur's social capital on their access to information, and how such access improves the performance of their entrepreneurial project. Design/methodology/approach - A structural equations model (SEM) is estimated and validated from a database including information from 282 Argentinean entrepreneurs who answered a questionnaire specifically designed for this research. The analysis of this model allowed the impact of dependent latent variables on the performance of the start-up to be determined. Findings - The performance of an entrepreneurial project depends on an entrepreneur's access to finance, markets and information. S…
Measuring organisational learning capability among the workforce
2007
PurposeThe present study sets out to propose and validate a measurement scale that aims to capture the organisational capability to learn, based on a comprehensive analysis of the facilitating factors for learning. The organisational learning capability scale consists of 14 items grouped into five dimensions: experimentation, risk taking, interaction with the external environment, dialogue, and participative decision making.Design/methodology/approachData were collected from eight Spanish ceramic tile manufacturers. The survey was addressed to shop floor workers. A total of 157 valid questionnaires were obtained, representing a response rate of 61 per cent. Using confirmatory factor analysi…
Towards a more humanistic understanding of organizational trust
2011
PurposeThe aim of this paper is to propose a wider and more humanistic understanding of the phenomenon of trust and “trust building” through a dialogue between ethics and social sciences.Design/methodology/approachThis paper offers a constructive critical review of the explanation of trust proposed by Mayer et al. in their 1995 seminal article, and expands this by considering the ethical dimension and the role of virtues.FindingsThe integrative model of organizational trust by Mayer et al. lacks a specific reference to the role played by human will and the ability to make free choices. When assessing the trust built in a relationship, an explicit consideration of human will should be includ…
