Artificial Intelligence and Human Resources Management: A Bibliometric Analysis

Artificial Intelligence (AI) is increasingly present in organizations. In the specific case of Human Resource Management (HRM), AI has become increasingly relevant in recent years. This article aims to perform a bibliometric analysis of the scientific literature that addresses in a connected way the application and impact of AI in the field of HRM. The scientific databases consulted were Web of Science and Scopus, yielding an initial number of 156 articles, of which 73 were selected for subsequent analysis. The information was processed using the Bibliometrix tool, which provided information on annual production, analysis of journals, authors, documents, keywords, etc. The results obtained show that AI applied to HRM is a developing field of study with constant growth and a positive future vision, although it should also be noted that it has a very specific character as a result of the fact that most of the research is focused on the application of AI in recruitment and selection actions, leaving aside other sub-areas with a great potential for application

Positron annihilation study of defect distribution in 8YSZ nanostructure

The impact of the interfacial contribution on overall properties increases with decreasing grain size of polycrystalline materials. It is well known that distribution and size of cluster defects are rather different in bulk than grain boundaries. In light of "bottom-up" approaches, a study at the atomic level determining the distribution of crystallographic defects could clarify their contribution to the macroscopic properties, and then differentiate materials for outstanding or precise applications. In this work, Positron Annihilation Spectroscopy (PAS) is used to characterize the distribution of defects within 8 mol% Y₂O₃-stabilized zirconia (8YSZ) structures prepared by sintering through three different thermal treatments, i.e. a conventional thermal cycle in air and N₂/H₂ atmosphere, and a fast firing cycle in air, which lead to average grain sizes < 260 nm.The authors would like to acknowledge the financial support from the Spanish Government through the projects MAT2009-14448-C02-01 and IPT-310000-2010-12.Publicad

Effect of highly dispersed yttria addition on thermal stability of hydroxyapatite

The capability of the colloidal method to produce yttria (Y₂O₃) dispersed hydroxyapatite (HA) has been investigated as an alternative method to the conventional method of mechanical mixing and sintering for developing HA-based materials that could exhibit controllable and enhanced functional properties. A water based colloidal route to produce HA materials with highly dispersed Y₂O₃ has been applied, and the effect of 10 wt.% Y₂O₃ addition to HA investigated by thermal analysis, X-ray diffraction and Fourier transform infrared spectroscopy. These measurements evidence a remarkable effect of this Y₂O₃ addition on decomposition mechanisms of synthetic HA. Results show that incorporation of Y₂O₃ as dispersed second phase is beneficial because it hinders the decomposition mechanisms of HA into calcium phosphates. This retardation will allow the control of the sintering conditions for developing HA implants with improved properties. Besides, substitution of Ca⁻2+ with Y⁻3+ ions appears to promote the formation of OH- vacancies, which could improve the conductive properties of HA favorable to osseointegration.This work has been supported by the Ministry of Science and Innova tion of Spain (MICINN) under contracts MAT2009 14448 C02 01 and IPT 310000 2010 12, and Regional Government of Madrid through the ESTRUMAT CM program (MAT 1585).Publicad

Aplicación de un programa basado en el soporte de autonomía en las clases de Educación Física

The purpose of this study is to know the effects of a autonomy support program through the Physical Education lessons on the psychological needs satisfaction, behavioral regulation and teacher interpersonal style. Sample were 61 students (25 boys and 36 girls) aged between 14 and 17 years (M = 14.97; DT = .85), belonging to two educational centres in Spain. Students were randomly divided In two groups (control and experimental). The instruments used were the Basic Psychological Needs Satisfaction Scale, the Behavioral Regulation Questionnaire in Sport and the Interpersonal Teacher Style Questionnaire. The teachers applied in the experimental group the autonomy support program during the Physical Education lessons in a total of eight weeks. The results showed statistically significant differences regarding the relation with the others (p&lt;.01) and the perception of teacher autonomous style (p&lt;.05), not finding significant differences with respect to the other variables. As a main conclusion to indicate that a program based on the promotion of autonomy may be optimal for the increase relations between students.El objetivo de este estudio es conocer los efectos de un programa basado en el soporte de autonomía a través de las clases de Educación Física sobre las necesidades psicológicas básicas, la regulación conductual y la percepción del estilo interpersonal del docente.

Temporary analysis of land use changes in Pine and mixed forests in Mexico

Objective: To assess the surface changes that occurred in pine forests, mixed forests and secondary vegetation of pine and mixed forests, at the national level, during the period 2001 to 2013. Design/methodology/approach: We used the Land Use and Vegetation (USV) coverages of Series II (from 2001) and V (from 2013) of the National Institute of Statistics and Geography, of scales 1: 250,000 as primary sources of information. The classes on both coverages were grouped and homogenized, focusing on pine and mixed forests. The exchange rates and transition indicators were estimated for the analysis: estimated profit and loss surfaces, persistence indices, of exchanges and net changes, as well as the gain and loss indices to persistence. Results: The rate of changes are negative for primary forests (pine and mixed) is in a range of 0.80 to 1.84. It was observed that 120,047 km2 (57.72%) were stable surfaces; however, 36 986 km2 (18.00%) were from losses, 14 369 km2 from gains and 28 738 km2 (14.00%) from different categories. During the period analyzed, 13.69% of the primary forests(2001)&nbsp; passed to secondary vegetation in 2013. Study limitations/implications: To observe the influence of other categories, it would be important to incorporate them through the study to analyze the system globally through the country. Findings/Conclusions: The persistence area of primary forests is important for generating conservation policies.Objective: to evaluate the changes in land use that occurred in Pine and mixed forests, at the national level during the period 2001 to 2013.Design/Methodology/Approach: layers of Land Use and Vegetation (Sp. equ. USV) of Series II (from 2001) and V (from 2013) of the Instituto Nacional de Estadística y Geografía, scale 1: 250,000 were used. Different categories of vegetation under study were reclassified and homogenized for both covers. Rates of change and indicators of transitions were estimated for the spatial-temporary analysis: surfaces of estimated losses and gains, indices of persistence, exchanges and net changes; also, indices of gain and loss to persistence.Results: the rate of negative change for primary forests (Pine and mixed) ranges from 0.80 to 1.84. It was observed that 120 047 km2 (57.72%) were stable surfaces. However, 36 986 km2 (18.00%) were losses, 14 369 km2 gains and 28 738 km2 (14.00%) between categories. It was observed from 2001 to 2013 that 13.69% of the area corresponding to primary forests which existed in 2001 became part of secondary vegetation in 2013.Study limitations/Implications: in order to observe the influence of other categories, it would be important to incorporate more classes throughout the study to be analyzed globally in the system throughout the country.Findings/Conclusions: The persistence of the coverage of primary forests is important to design conservation policie

mcr-Colistin resistance genes mobilized by IncX4, IncHI2, and IncI2 plasmids in Escherichia coli of pigs and white stork in Spain

Colistin has become the last-line antimicrobial for the treatment of multidrug resistant (MDR) Enterobacterales in human medicine. To date, several colistin resistance genes have been described. Of them mcr-1 is disseminated worldwide in Escherichia coli of human and animal origin. The aim of this study was to characterize mcr-mediated resistance plasmids from E. coli of animal origin in Spain. From our strain collection, 70 E. coli of pig origin collected between 2005 and 2014 (10 per year, except for years 2009-2010-2013) were randomly selected and screened for the presence of mcr-genes. Additionally, 20 E. coli isolated in 2011 from white storks (Ciconia ciconia) from the same urban household waste landfill associated colony were also included. Whole genome sequencing of mcr-positive isolates was carried out on a MiSeq (Illumina). Hybrid whole genome sequencing strategy combining nanopore and Illumina technologies were performed in a selection of isolates to close the genomes and plasmids and identify the presence of antimicrobial resistance genes. Minimum inhibitory concentration (MIC) was used to assess the susceptibility to colistin. Mating experiments were carried out to evaluate transferability of the mcr-genes. A total of 19 mcr-1 and one mcr-4 positive isolates were detected, 15 from pigs distributed during the study period, and five from storks collected in 2011. No other mcr-variants were found. The MICs for colistin ranged between 4 and >4 mg/L. High diversity of STs were detected among the mcr-1 positive E. coli isolates, with only ST-10 shared between pigs and white storks. Except for one isolate, all were genotypic and phenotypically MDR, and five of them also harbored cephalosporin resistance genes (bla CTX-M- 14, bla SHV- 12, and three bla CMY- 2). mcr-1 genes were mobilizable by conjugation, associated with IncX4, IncHI2, and IncI2 plasmids. In our study, mcr-1 genes have been circulating in pig farms since 2005 harbored by a variety of E. coli clones. Its persistence may be driven by co-selection since plasmids containing mcr-1 also exhibit resistance to multiple drugs used in veterinary medicine. Furthermore, this is the first report of the presence of mcr-1 gene in isolates from white storks in Spain. This finding highlights the potential importance of wildlife that forage at urban household waste landfills in the transmission and spread of colistin resistance genes.info:eu-repo/semantics/publishedVersio

Regulation of SCF TIR1/AFB E3 ligase assembly by S-nitrosylation of Arabidopsis SKP1-like1 impacts on auxin signaling

The F-box proteins (FBPs) TIR1/AFBs are the substrate recognition subunits of SKP1–cullin–F-box (SCF) ubiquitin ligase complexes and together with Aux/IAAs form the auxin co-receptor. Although tremendous knowledge on auxin perception and signaling has been gained in the last years, SCFTIR1/AFBs complex assembly and stabilization are emerging as new layers of regulation. Here, we investigated how nitric oxide (NO), through S-nitrosylation of ASK1 is involved in SCFTIR1/AFBs assembly. We demonstrate that ASK1 is S-nitrosylated and S-glutathionylated in cysteine (Cys) 37 and Cys118 residues in vitro. Both, in vitro and in vivo protein-protein interaction assays show that NO enhances ASK1 binding to CUL1 and TIR1/AFB2, required for SCFTIR1/AFB2 assembly. In addition, we demonstrate that Cys37 and Cys118 are essential residues for proper activation of auxin signaling pathway in planta. Phylogenetic analysis revealed that Cys37 residue is only conserved in SKP proteins in Angiosperms, suggesting that S-nitrosylation on Cys37 could represent an evolutionary adaption for SKP1 function in flowering plants. Collectively, these findings indicate that multiple events of redox modifications might be part of a fine-tuning regulation of SCFTIR1/AFBs for proper auxin signal transduction.This work has been supported by grants from CONICET (PIP 0202 to M.C.T), Universidad Nacional de Mar del Plata and Agencia Nacional de Promoción Científica y Tecnológica, -Argentina (PICT 1167 to M.C.T and PICT 2421 to C.A.C); from the Spanish Government (PS09/00101 and PI12/00875 to A.M.R., cofinanced by the European Union ERDF), and by the Argentinian-Spanish Integrated Action ES/11/02 / PRIAIBAR- 2011-0782.

Wind and turbulence relationship with NO2 in an urban environment: a fine-scale observational analysis

It is well known that meteorology plays an important role in the diurnal evolution of pollutants, especially those variables related to atmospheric dispersion. Most studies typically relate the concentration of some pollutants with wind speed from conventional anemometers; however, the use of turbulence variables is less common, in part because the needed instruments are not so typical in standard air-quality stations. In this work, we compare the wind-NO2 relationship with the turbulence-NO2 one using observational data from two field campaigns developed in Madrid (winter and summer). The turbulence data comes from two sonic anemometers deployed at different locations: one close to the street and the other at the top of a nearby tall building. The results indicate that the turbulent variables correlate better with the pollutant concentration than the wind speed when using data from the street sonic, while the contrary is found when using the terrace sonic. These data are also used to perform a fine-scale analysis of the turbulent diffusion-NO2 behaviour during a very-stable period in winter, when the turbulence typically shows a decrease in the evening transition, causing the highestNO2 concentrations. Conversely, under these conditions, the formation of thermally-driven winds is also favoured later in the night, which favours the pollutant dispersion and cleaning of the air. The important role of these dynamical processes on the NO2 evolution highlights the importance of the correct understanding of small-scale atmospheric processes to understand their relationship with the concentration of pollutants
