Los Recursos Humanos en la empresa industrial: un análisis empírico sobre la eficiencia del capital humano

Aunque existe un amplio acuerdo acerca de que en la economía actual los principales recursos competitivos son la innovación y el talento, más que los capitales físico y financiero, no hay un método objetivo para la medida de estos nuevos tipos de capitales. Para contribuir a atenuar esta importante carencia, se propone un método estadístico objetivo, contrastado y práctico, que permite: a) medir el capital humano, o cualquier otro capital intangible, de una empresa, y b) establecer cuáles son los factores que determinan su formación, así como en qué medida contribuyen a ella. De esta forma, los responsables en las distintas instituciones pueden conocer qué medidas tomar para optimizar los resultados, en este importante aspecto de su gestión, facilitándoles así la toma objetiva y acertada de decisiones. Como aplicación, en esta investigación se construye un índice de capital humano (ICH), mostrándose su aplicación en una muestra significativa de empresas manufactureras españolas. A lo largo del estudio se contrastan y analizan las claves de un nuevo paradigma económico, que avanza desde la economía industrial a la economía del conocimiento con sus implicaciones y efectos: la importancia del capital humano y de su gestión eficiente en el contexto que promueven las tecnologías de la información y de la comunicación. Además, se analizan la importancia del capital humano y de su gestión eficiente en el contexto que promueven las tecnologías de la información y de la comunicación, se revisan los estudios que relacionan la gestión de los Recursos Humanos con los resultados empresariales y, finalmente, se evalúan empíricamente la productividad y eficiencia del capital humano en la empresa industrial española con los datos proporcionados por la Encuesta de Estrategias Empresariales (ESEE). Los resultados ponen de relieve la importancia del esfuerzo innovador en la acumulación de capital humano por parte de las empresas. Empresas con mayor personal destinado a I+D ofrecen mayores valores del índice. Además, otras variables como la duración de la jornada laboral, la política de formación por parte de la empresa hacia los trabajadores o la productividad ejercen una influencia positiva y significativa sobre el ICH. Se revelan como factores predominantes: la innovación, el personal destinado a I+D, la duración de la jornada laboral, la política de formación por parte de la empresa hacia los trabajadores y la productividad. Como conclusión se establece que la clave del éxito empresarial radica actualmente en la capacidad de innovar, la cual no sólo se consigue con el capital físico, sino con el talento de los empresarios y profesionales y con la mejora del rendimiento humano.
Saccadic Modulation of Neural Responses: Possible Roles in Saccadic Suppression, Enhancement, and Time Compression

Humans use saccadic eye movements to make frequent gaze changes, yet the associated full-field image motion is not perceived. The theory of saccadic suppression has been proposed to account for this phenomenon, but it is not clear whether suppression originates from a retinal signal at saccade onset or from the brain before saccade onset. Perceptually, visual sensitivity is reduced before saccades and enhanced afterward. Over the same time period, the perception of time is compressed and even inverted. We explore the origins and neural basis of these effects by recording from neurons in the dorsal medial superior temporal area (MSTd) of alert macaque monkeys. Neuronal responses to flashed presentations of a textured pattern presented at random times relative to saccades exhibit a stereotypical pattern of modulation. Response amplitudes are strongly suppressed for flashes presented up to 90 ms before saccades. Immediately after the suppression, there is a period of 200–450 ms in which flashes generate enhanced response amplitudes. Our results show that (1) MSTd is not directly suppressed, rather suppression is inherited from earlier visual areas; (2) early suppression of the visual system must be of extra-retinal origin; (3) postsaccadic enhancement of neural activity occurs in MSTd; and (4) the enhanced responses have reduced latencies. As a whole, these observations reveal response properties that could account for perceptual observations relating to presaccadic suppression, postsaccadic enhancement and time compression.
Integration of thin film resonator devices onto SiGe substrates

Bulk acoustic wave resonators and filters have been fabricated over the frequency range from 300 MHz to over 12 GHz. At higher frequencies, it is sometimes desirable to have resonators and filters integrated into the active device substrate. Full integration allows shorter lead lengths and reduced parasitics for filters and resonators used to control oscillator frequency. This paper reports on the initial results of a project to integrate thin film resonators and filters on semiconductor IC substrates, principally SiGe, and the issues associated with full integration.
Dual estimation of lithium-ion battery internal resistance and SOC based on the UKF

Lithium-ion batteries have been widely used in many fields. In order to make the battery work on good conditions, people should monitor its working states continuously. The two important working state of a battery are its internal resistance and the State of Charge (SOC). A dual estimation method of the internal resistance and the SOC based on the Unscented Kalman Filter (UKF) is proposed. The internal resistance is regarded as a parameter of a mathematical model, which reflects the relationship between the voltage and the SOC, the discharging rate and the temperature. The dual estimation of the internal resistance and the SOC are then done alternately with different UKF algorithms. Experimental results show that the proposed method is effective.
The autonomic nervous system and Dretske on phenomenal consciousness

Title page Representational theories propose a set of sufficient conditions for a state to be phenomenally conscious. It turns out that insofar as these conditions have been worked out in detail, the autonomic nervous system (ANS) ought to be conscious but of course it’s not. In this paper, we’ll describe only a tiny portion of the complexities of the ANS, using these to counterexample only a single theory of phenomenal consciousness, namely, Fred Dretske’s. But we think the ANS comparison strategy is a fruitful one in general, and we hope to convince you of this too.
El vínculo Inversión Extranjera Directa y desigualdad salarial en los estados mexicanos

Using state information we analyze the link among foreign investment and wage inequality in Mexico. We show the existence of an increase of the demand of qualified work, which has had major importance in the states with major reception of foreign direct investment (FDI), since also FDI tends to concentrate itself geographically. The regression results indicate that 1% of increase in the per capita foreign investment has an effect near to 6% of increase of the wage inequality. Meanwhile, when we considerer only the set of states with major reception of foreign investment a negative effect of 12% is estimated.
Nature and Risk of Victimization

The Census of Juveniles in Residential Placement, Juvenile Residential Facility Census, and Survey of Youth in Residential Placement (SYRP) comprise the nation’s most comprehensive data collection program on youth in custody and the facilities that hold them. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) sponsors these surveys and disseminates the findings to provide a snapshot of the youth who comprise the nation’s juvenile placement population, the facilities where they reside, and the conditions in which they live.
On the Effect of Self-Interference Cancelation in MultiHop Wireless Networks

In a wireless network, the problem of self-interference arises when a node transmits and receives simultaneously in the same frequency band. So far only two extreme approaches to circumvent this problem were thoroughly investigated in the literature. The first one prevents any node to transmit and receive simultaneously which may lead to a too conservative design. The second one assumes perfect self-interference cancelation which can be too optimistic since it ignores all possible technological limitations. To fill this gap, we provide a method based on complementary geometric programming for evaluating the gains achievable at the network layer when the network nodes employ self-interference cancelation techniques with different degrees of accuracy. The gains are evaluated in terms of average sum rate and average network congestion by using a network utility maximization framework. The method provides insights into the behavior of different network topologies when self-interference cancellation is employed in nodes. In addition, it can be used to assess the required degrees of accuracy of the self-interference in order to achieve substantial benefits. Thus, from a network design perspective, the proposed method is very beneficial. Numerical results suggest that the benefits from self-interference cancelation are more pronounced in tandem wireless network setups in which the network nodes are located in a linear grid.
A Topology Partition Algorithm Based on Link Coarsening in Parallel Network Simulation

Today’s networks are facing more and more serious large-scale network attack such as worm and botnet. While such attacks can’t and shouldn’t be reproduced in the real network, network simulation is become more and more popular during the research. As the prerequisite of network simulation, topology partition influences the performance of simulation significantly. We suggest a new topology partition algorithm in parallel network simulation. This algorithm is a kind of agglomerative hierarchical clustering methods based on link coarsening. The experiment shows that our algorithm can finish partition on current computers in acceptable time for even around millions of vertices. Furthermore, the links between different sub-domains are fewer and the connectivity in each sub-domain is also guaranteed. Compared with the results of KMETIS, the new algorithm can reduce the edgecut more than 90% in general.
International Society for Sexual Medicine's guidelines for the diagnosis and treatment of premature ejaculation.

INTRODUCTION Over the past 20 years our knowledge of premature ejaculation (PE) has significantly advanced. Specifically, we have witnessed substantial progress in understanding the physiology of ejaculation, clarifying the real prevalence of PE in population-based studies, reconceptualizing the definition and diagnostic criterion of the disorder, assessing the psychosocial impact on patients and partners, designing validated diagnostic and outcome measures, proposing new pharmacologic strategies and examining the efficacy, safety and satisfaction of these new and established therapies. Given the abundance of high level research it seemed like an opportune time for the International Society for Sexual Medicine (ISSM) to promulgate an evidenced-based, comprehensive and practical set of clinical guidelines for the diagnosis and treatment of PE. AIM Develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of PE for family practice clinicians as well as sexual medicine experts. Method. Review of the literature. RESULTS This article contains the report of the ISSM PE Guidelines Committee. It affirms the ISSM definition of PE and suggests that the prevalence is considerably lower than previously thought. Evidence-based data regarding biological and psychological etiology of PE are presented, as is population-based statistics on normal ejaculatory latency. Brief assessment procedures are delineated and validated diagnostic and treatment questionnaires are reviewed. Finally, the best practices treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with PE, in facilitating treatment of their patients. CONCLUSION Development of guidelines is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to a more complete understanding of the pathophysiology as well as new efficacious and safe treatments for this sexual dysfunction. Therefore, it is strongly recommended that these guidelines be re-evaluated and updated by the ISSM every 4 years.
Should an OEM Retain Component Procurement when the CM Produces Competing Products

We consider a large original equipment manufacturer (OEM) who relies on a contract manufacturer (CM) to produce her product. In addition to the OEM's product, the CM also produces for a smaller OEM. Both the larger OEM and the CM can purchase the component from the supplier, but their purchase prices may differ and remain unknown to each other. The main question we address is whether the larger OEM should retain component procurement by purchasing components from the supplier and reselling to the CM (buy–sell), or outsource component procurement by letting the CM purchase directly from the supplier (turnkey). We show that, under buy–sell, the larger OEM's optimal strategy is to resell components at the highest possible component purchase price of the CM (i.e., the street price). By comparing buy–sell and turnkey, we find that a CM with low component price is better off under turnkey, even though under buy–sell he receives more profits through the products sold to the smaller OEM. Furthermore, the larger OEM's preference between buy–sell and turnkey depends on her component price, the volatility of the CM's component price and substitutability between the two products.
Review of iterative Fourier-transform algorithms for beam shaping applications

We present a comparison of some of the most used iterative Fourier transform algorithms (IFTA) for the design of continuous and multilevel diffractive optical elements (DOE). Our aim is to provide optical engineers with advice for choosing the most suited algorithm with re- spect to the task. We tackle mainly the beam-shaping and the beam- splitting problems, where the desired light distributions are almost binary. We compare four recent algorithms, together with the historical error- reduction and input-output methods. We conclude that three of these algorithms are interesting for continuous-phase kinoforms, and two, namely the three-step method proposed by Wyrowski and the over- compensation of Prongue ´, still perform well with multilevel- and binary- phase DOE. © 2004 Society of Photo-Optical Instrumentation Engineers.
Efficient deployment algorithms for ensuring coverage and connectivity of wireless sensor networks

Sensor deployment is a critical issue since it reflects the cost and detection capability of a wireless sensor network. Although lots of work has addressed this issue, most of them assume that the sensing field is an open space and there is a special relationship between the communication range and sensing range of sensors. In this work, we consider the sensing field as an arbitrary-shaped region possibly with obstacles. Besides, we allow an arbitrary relationship between the communication range and sensing range, thus eliminating the constraints of existing results. Our approach is to partition the sensing field into smaller sub-regions based on the shape of the field, and then to deploy sensors in these sub-regions. Simulation results show that our method requires fewer sensors compared to existing results.
On Permuting Ability of a 2D Torus under XY routing

This paper introduces an exploration to permuting ability of a 2D torus under deterministic XY routing. The research is carried out for a number of communication models, namely, unidirectional uniaxial, bidirectional uniaxial, unidirectional biaxial, and bidirectional biaxial. Necessary and sufficient conditions of blocking occurrence in a 2D torus for uniaxial models are expressed mathematically with the use of congruence notion from number theory. Some examples of applying the technique are given. Frequently used permutations admissibility to a 2D torus of varied size under XY routing is checked computationally for aforementioned communication models. A simple way for realizing perfect shuffle and bit reversal permutations on 2D torus under XY routing is found.
Content-Based Spam Filtering on Video Sharing Social Networks

In this work we are concerned with the detection of spam in video sharing social networks. Specifically, we investigate how much visual content-based analysis can aid in detecting spam in videos. This is a very challenging task, because of the high-level semantic concepts involved; of the assorted nature of social networks, preventing the use of constrained a priori information; and, what is paramount, of the context dependent nature of spam. Content filtering for social networks is an increasingly demanded task: due to their popularity, the number of abuses also tends to increase, annoying the user base and disrupting their services. We systematically evaluate several approaches for processing the visual information: using static and dynamic (motionaware) features, with and without considering the context, and with or without latent semantic analysis (LSA). Our experiments show that LSA is helpful, but taking the context into consideration is paramount. The whole scheme shows good results, showing the feasibility of the concept.
Capacitive RF MEMS Switches Fabricated in Standard 0.35-$\mu{\hbox{m}}$  CMOS Technology

The objective of this paper is to investigate the integration of capacitive type RF microelectromechanical systems (MEMS) switches in a standard CMOS technology. A maskless monolithic integration process dedicated to electrostatically actuated capacitive type RF MEMS switches is developed and optimized. The fabricated switches consist of composite metal-dielectric warped membranes. The warped-plate structure is used to increase the capacitance ratio of the switch. The switches are fabricated using the interconnect metal and dielectric layers available in a standard 0.35-μm CMOS process. Measurement results for the first switch show an insertion loss less than 0.98 dB, a return loss below 13 dB up to 20 GHz in the up-state, and a down-state isolation of 12.4-17.9 dB from 10 to 20 GHz. The capacitance ratio is enhanced up to 91:1 using the warped-plate structure. A second cascaded switch consisting of two shunt capacitive switches and a slow-wave high-impedance transmission line section is designed and fabricated for high-isolation applications. The measured insertion loss for this switch is less than 1.41 dB up to 20 GHz, the return loss is below 19 dB, and the isolation is 19-40 dB across the frequency band from 10 to 20 GHz. The proposed RF MEMS switches can be used in millimeter-wave CMOS RF front-ends where multiband functionality and reconfigurability is required.
A computational model for the estimation of localisation uncertainty

A computational model for prediction of localisation uncertainty of phantom auditory sources is proposed. The interaural level and time difference pairs due to point sources in free field are used as a reference. The mismatch between these “natural” pairs and interaural time and level difference pairs elicited by phantom sources is quantified by means of the 0.5-norm distance, which is justified on psychoacoustic grounds. The model is validated by results of subjective listening tests, achieving a high level of correlation with experimental data.
Early Drug Discovery Prediction of Proarrhythmia Potential and Its Covariates

from different backgrounds introduced the audience to the current safety testing paradigm, the latest achievements within drug safety and remaining hurdles regarding the integration of multiple sources of data acquired both at the preclinical and clinicallevel,andtheirtranslationtothehumaninvivosituation. Despite a reasonable knowledge of the mechanisms related to proarrhythmic cardiotoxicity, there are still questions whether the new paradigm of testing will be able to provide all stakeholders with a sufficient level of confidence with the application of these novel concepts and models to drug safety. This article gives a short overview of the discussed problems, summarizes the discussion, and gives a flavor of a new cardiac safety testing pathway likely to be introduced in the near future. Some of the statements in the text, like the feasibility of the individualized risk assessment, can be contradictory what was left intentionally and shows the line of discussion between speakers. The three leading topics include a description of the molecular and clinical background of drug-induced proarrhythmic effects, a brief presentation of current methods used in the early prediction of such effects together with anticipated changes in the testing paradigm and a discussion of the in vitro–in vivo extrapolation approach, all of which promise the possibility of risk assessment at the individual patient level.
Energy Consumption and Scalability Evaluation for Software Transactional Memory on a Real Computing Environment

Transactional Memory is a concurrent programming abstraction that overcomes several of the limitations found in traditional synchronization mechanisms. As it is a more recent abstraction, little is known about energy consumption of Software Transactional Memories (STM). In this context, this work presents an analysis and characterization of energy consumption and performance of four Transactional Memory libraries: TL2, Tiny STM, Swiss TM, and Adapt STM, using the STAMP benchmarks. Although most works in the state-of-the-art chose to evaluate Transactional Memories through simulation, in this work the benchmarks are run in actual computers, avoiding the known issues with modeling power consumption in simulators. Our results show that Swiss TM is the most efficient library of the four in terms of energy consumption and performance for the default configurations, followed by Adapt STM, Tiny STM, and TL2, for most of the execution scenarios and 8 threads at most. STM's scalability is directly tied to the strategies for detection and resolution of conflicts. In this perspective, Adapt STM is the best STM for applications with short transactions, Swiss TM presents the best results for medium transactions, and long transactions with medium/high contention are best handled by TL2. On the other hand, Tiny STM shows the worst scalability for most scenarios, but with good results for applications with very small abort rates.
Zipf’s law outside the middle range

Zipf (1949) already noted that the linear relationship that he observed between log frequency and log rank is strongest in the middle range: both very high and very low frequency items tend to deviate from the log-log regression line. In this paper the causes for such deviations are investigated and a more detailed statistical model is offered. The subgeometric mean property of frequency counts is introduced and used in proving that the size of the vocabulary tends to infinity as sample size is increased without bounds.
