El rol del modelo de las competencias en la reconfiguración meritocrática de las pautas de negociación salarial en empresas argentinas: continuidades…
2020
The development of new models of work organization and the complementary advance of flexible guidelines for the use of the labor force had as a correlate a profound change in techniques for the evaluation of workers. Thus, the typical model of Fordism, based on qualifications, was replaced by a different one based on competencies, whereby the strong relationship of the former was abandoned with the determination of the technical knowledge required for each job to move to a system which the priority is placed in the individual attitude. The consequent individualization of performance evaluations can lead to a possible loss of objectivity. In this article we develop a theoretical comparison b…
Per-flow signalling extension across DiffServ domains
2003
This paper describes a framework devised to extend per-flow admission control operation across Differentiated Services domains. Although the specific case of interoperability with RSVP is under discussion, our proposal can be easily adapted to other hop-by-hop signalling protocols. In our framework, DiffSery border routers accomplish three tasks. First, during the set-up phase, flows are mapped onto PHB groups on the basis of their QoS and traffic specifications. Second, signalling packets are tunnelled into IP packets marked as “probes”, where the “probe” marking is a DCSP value associated to the considered PHB Group. Third, when the flow set-up is complete, flow data packets are marked as…
Quality and Innovation in the Organic Agro-Food Sector: Threats and Opportunities of Social and Managerial Innovation
2018
This study seeks to understand how innovation in the organic agro-food sector has evolved, studying the main challenges facing the sector as a consequence of its growth. Through the study and analysis of literature we reflect on the threats and opportunities facing the sector. We also used two expert panels to help us cross-reference and complete the information available from previous studies. The organic agro-food sector was born as a social and radical innovation based on specific values and principles, which include respect for nature and sustainability, ecology, no pollution, equity and a close relationship with consumers. In this chapter, we explain how regulations and the interplay…
Aperiodic Diffract: Study of diffraction gratings
2014
In this work we introduce a virtual laboratory, APERIODIC DIFFRACT, developed in Matlab GUI (Graphical User Interface) as an informatics tool for teaching the diffractive properties of aperiodic gratings. This GUI allows the student to generate aperiodic sequences by iterating and lets to study the spectra for different iterating orders.<br /><br />
International positioning of the Spanish psychology journals
2020
[ES]: Se presentan los resultados del análisis de la difusión y circulación del número de revistas españolas en diferentes bases de datos, nacionales e internacionales. Para ello se realiza un estudio de las revistas que contienen las principales bases de datos bibliográficas hasta el año 2017. El aumento de la presencia de revistas españolas de psicología en las diferentes bases de datos es un indicador que determina el crecimiento y la madurez de esta disciplina y aporta una visión interesante de la actividad científica en psicología y su situación en el contexto internacional. Se muestra que las políticas de estado y las campañas de posicionamiento de universidades, asociaciones y colegi…
Industry 4.0 transition: a systematic literature review combining the absorptive capacity theory and the data–information–knowledge hierarchy
2021
Purpose The effect of the transition toward digital technologies on today’s businesses (i.e. Industry 4.0 transition) is becoming increasingly relevant, and the number of studies that have examined this phenomenon has grown rapidly. However, systematizing the existing findings is still a challenge, from both a theoretical and a managerial point of view. In such a setting, the knowledge management (KM) discipline can provide guidance to address such a gap. Indeed, the implementation of fundamental digital technologies is reshaping how firms manage knowledge. Thus, this study aims to critically review the existing literature on Industry 4.0 from a KM perspective. Design/methodology/approach …
A dynamic panel study on digitalization and firm's agility: What drives agility in advanced economies 2009–2018
2021
Abstract Firm agility today is not a factor of competitiveness or success but a survival instrument on the market. Disruptive innovations and technological advancement, together with digitalization, change the role of firm agility. We show that the link between the national/industry level of digitalization and firm agility is statistically robust and essential. We study the link on data from 2009 to 2018 in fifteen EU advanced economies using dynamic panel data modeling. The digitalization impact level differs across firms by ownership type (family to non-family firms). Agility in family firms is strongly influenced by the national/industry level of digitization and investments in intangibl…
Decision Support for Disaster Risk Management: Integrating Vulnerabilities into Early-Warning Systems
2014
International audience; Despite the potential of new technologies and the improvements of early-warning systems since the 2004 Tsunami, damage and harm caused by disasters do not stop to increase. There is a clear need for better integrating the fragmented landscape of researchers and practitioners working on different aspects of decision support for disaster risk reduction and response. To demonstrate and discuss the advantages of integrated systems, we will focus in this paper on vulnerabilities and early-warning systems. While vulnerabilities are mostly used to allocate risk management resources (preparedness), early-warning systems are designed to initiate the response phase. Indicator …
Span-Program-Based Quantum Algorithms for Graph Bipartiteness and Connectivity
2016
Span program is a linear-algebraic model of computation which can be used to design quantum algorithms. For any Boolean function there exists a span program that leads to a quantum algorithm with optimal quantum query complexity. In general, finding such span programs is not an easy task. In this work, given a query access to the adjacency matrix of a simple graph G with n vertices, we provide two new span-program-based quantum algorithms:an algorithm for testing if the graph is bipartite that uses $$On\sqrt{n}$$ quantum queries;an algorithm for testing if the graph is connected that uses $$On\sqrt{n}$$ quantum queries.
New Developments in Quantum Algorithms
2010
In this survey, we describe two recent developments in quantum algorithms. The first new development is a quantum algorithm for evaluating a Boolean formula consisting of AND and OR gates of size N in time O(\sqrt{N}). This provides quantum speedups for any problem that can be expressed via Boolean formulas. This result can be also extended to span problems, a generalization of Boolean formulas. This provides an optimal quantum algorithm for any Boolean function in the black-box query model. The second new development is a quantum algorithm for solving systems of linear equations. In contrast with traditional algorithms that run in time O(N^{2.37...}) where N is the size of the system, the …
