Prácticas de alto rendimiento : un enfoque configuracional aplicado al caso español
2008
Roberto.Luna@uv.es Joaquin.Camps@uv.es El principal objetivo de esta investigación es analizar diferentes configuraciones de prácticas de recursos humanos (RH) que se dan en una muestra de 183 empresas españolas. A continuación se relacionan estas configuraciones con las estrategias competitivas de las empresas con el fin de validar la estructura configuracional obtenida. Los resultados muestran tres tipos de configuraciones. La primera, empresas con prácticas de alto rendimiento (PAR) (37,5%), se caracteriza por un intenso y generalizado uso de dichas prácticas. La segunda, empresas desarrollando PAR (46,4%), se caracteriza por el uso de una amplia gama de PAR, pero con una limitada aplica…
A test of transferability for landslides susceptibility models under extreme climatic events: application to the Messina 2009 disaster
2014
A model building strategy is tested to assess the susceptibility for extreme climatic events driven shallow landslides. In fact, extreme climatic inputs such as storms typically are very local phenomena in the Mediterranean areas, so that with the exception of recently stricken areas, the landslide inventories which are required to train any stochastic model are actually unavailable. A solution is here proposed, consisting in training a susceptibility model in a source catchment, which was implemented by applying the binary logistic regression technique, and exporting its predicting function (selected predictors regressed coefficients) in a target catchment to predict its landslide distribu…

A Practical Approach to EA Planning and Development: the EA Management Grid
2004
Enterprise Architecture is gaining interest as a managerial tool for managing corporate ICT assets and their interplay. Our prior studies indicate that an ICT provider’s viewpoint on EA consulting, planning and development seems to be lacking in the proposed methodologies. Considering both literature and practical EA cases, we suggest an approach that supports restricted assignments in EA management. We present an EA Grid for the management of EA descriptions, requirements, constraints, as well as project tasks and deliverables, task preliminaries and dependencies in EA consulting and development. peerReviewed
The outcomes of Ilizarov treatment in aseptic nonunions of the tibia stratified by treatment strategies and surgical techniques.
2020
Abstract INTRODUCTIONNonunions of the tibia, particularly those located in the distal third of the bone, are relatively common in clinical practice. There is no gold standard for the treatment of nonunions of the tibia. The purpose of our study was to assess the results of treatment with the Ilizarov method in patients with aseptic nonunions of the tibia, depending on the employed treatment strategies and surgical techniques.MATERIALS AND METHODSA total of 75patients with Ilizarov treatment of aseptic nonunions of the tibia were evaluated in the study. The patients’s mean age at the beginning of treatment was 46years.The mean follow-up period was 10years and 11months.The evaluated patients …
Image Segmentation by Deep Community Detection Approach
2017
International audience; To address the problem of segmenting an image into homogeneous communities this paper proposes an efficient algorithm to detect deep communities in the image by maximizing at each stage a new centrality measure, called the local Fiedler vector centrality (LFVC). This measure is associated with the sensitivity of algebraic connectivity to node removals. We show that a greedy node removal strategy, based on iterative maximization of LFVC, has bounded performance loss relative to the optimal, but intractable, combinatorial batch removal strategy. A remarkable feature of this method is the ability to segments the image automatically into homogeneous regions by maximizing…
Do irresponsible corporate activities prevent membership in sustainable stock indices? The case of the Dow Jones Sustainability Index world
2021
Abstract The study analyses the real-life results from the DJSI World selection process and investigates whether companies are treated differently because of sectoral or geographical diversification needs of the index; furthermore, the question whether its methodology penalises ESG-related irresponsible corporate activities is investigated. The last is an important issue, as it is not unusual to find constituents of sustainable indices implicated in corporate scandals. This is a striking fact, contradicting the ethical and sustainable imperative such companies are supposed to comply with. The authors scrutinise data from a data panel containing 2872 firms between 2011 and 2016 and estimate …
Probabilistic inferences from conjoined to iterated conditionals
2017
Abstract There is wide support in logic, philosophy, and psychology for the hypothesis that the probability of the indicative conditional of natural language, P ( if A then B ) , is the conditional probability of B given A, P ( B | A ) . We identify a conditional which is such that P ( if A then B ) = P ( B | A ) with de Finetti's conditional event, B | A . An objection to making this identification in the past was that it appeared unclear how to form compounds and iterations of conditional events. In this paper, we illustrate how to overcome this objection with a probabilistic analysis, based on coherence, of these compounds and iterations. We interpret the compounds and iterations as cond…
The real-life performance of market timing with moving average and time-series momentum rules
2014
In this article, we revisit the myths regarding the superior performance of market timing strategies based on moving average and time-series momentum rules. These active timing strategies are very appealing to investors because of their extraordinary simplicity and because they promise substantial advantages over their passive counterparts. However, the ‘too good to be true’ reported performance of these market timing rules raises a legitimate concern as to whether this performance is realistic and whether investors can expect that future performance will be the same as the documented historical performance. We argue that the reported performance of market timing strategies usually contains…
Information Flows Among the Major Stock Market Areas
2001
The relationship between the index returns of the major stock markets has been analysed in many papers. These studies usually examine lead–lag relationships between markets, without distinguishing the influencing ability and the sensitivity of each of the markets. Additionally, these studies use indices that are not directly comparable — either because of the way the indices are calculated or because of the number of companies and sectors used to construct them. This paper addresses both points. First, all the analyses have been made using homogeneous indices designed by Morgan Stanley Capital International. Secondly, the information flow has been studied by applying the model proposed by P…
