    Abstract This paper adopts the Job Demands-Resources (JD-R) model to analyze workplace bullying among teachers. The data used for this research are obtained from the 5th European Working Conditions Survey. Given the objective of this work, a subsample of 261 education employees is collected: 48.7% of these teachers report having experienced workplace bullying (N = 127), while 51.3% indicate not considering themselves as bullied at work (N = 134). In order to test the research model and hypotheses, this study relies on the use of partial least squares (PLS-SEM), a variance-based structural equation modeling method. The study describes a workplace bullying prevalence rate of 4.4% among education employees. This work summarizes an array of outcomes with the aim of proposing, in general, that workplace bullying may be reduced by limiting job demands and increasing job resources.

    Abstract Despite considerable evidence that alien plants impact the fecundity, productivity and abundance of native plant species, support for alien plant species causing the widespread decline of native species is rare. Coexistence theory proposes that the outcome of competition between two species can be predicted through the invasion criterion, measured as a positive population-level growth rate of each competitor when that species is rare. Here we make use of coexistence theory to examine the likelihood of persistence of a native water fern (Azolla rubra) following invasion by an alien congener (Azolla pinnata) which has apparently displaced the native wherever their ranges overlap in New Zealand. We evaluate coexistence between the two water fern species using experimental measurements of population-level growth rates. We show that the alien A. pinnata has a higher fitness than A. rubra, which hinders coexistence between the two species. These experimental results match the rapid expansion of A. pinnata and the apparent decline of A. rubra observed in nature. Our study predicts that A. pinnata is capable of replacing its native congener, highlights the importance of fitness differences in invasion success, and demonstrates the value of experimental analyses of species coexistence for predicting longer-term invasion dynamics and impacts. Using experiments to test coexistence mechanisms between alien and native species is a valuable approach to predict invasion outcomes and one that can lead to insights on the long-term impacts of alien species, including extinction, on native species populations.

    Abstract Enzyme preparations of Candida antarctica B lipase (CAL-B) - immobilized on Eupergit C and partially modified Eupergit C supports - were tested for kinetic resolution of (R/S)-propranolol, using vinyl acetate as acyl donor, and toluene as organic solvent. The effects of (R/S)-propranolol concentration, vinyl acetate concentration and biocatalyst loading on the esterification and resolution of propranolol were studied. Additionally, different types of immobilized lipase derivatives were also evaluated in terms of its selectivity on kinetic resolution of (R,S)-propranolol. These derivatives showed different enantiomeric ratios (E), with high enantiomeric ratios (E=57) with CAL-B immobilized on Eupergit C supports.

    Abstract This study looks at the spatial distribution of robbery against residents as a function of nonstationary density and mobility patterns in the most densely populated city in Spain, Barcelona. Based on the geographical coordinates of mobile devices, we computed two measures of density of the ambient population and the tourist presence, for work days, weekends, and holidays in 2019. Negative binomial regressions are then estimated to analyse whether these measures are correlated with the risk of robbery, controlling for land use and the characteristics of the social environment. The model reveals that residents' chances of being exposed to robbery in Barcelona depend on the social relevance and tourism attractiveness of certain places at particular times of the year. Our results disclose two sources of social disorganization as stronger predictors of the occurrence of robbery in Barcelona, respectively linked to structural processes of residential instability and daily and seasonal mobility patterns. On the one hand, we found that the effect of the density of international tourists on the outcome variable is mediated by residential volatility, which is assumed to be associated with housing shortages in neighbourhoods where short-term vacation rentals are widespread. On the other hand, the ability to exert effective social control is significantly undermined in urban areas, where the ambient population and the volume of tourists outnumber the resident population, thus increasing incidents of robbery victimization. The implications of these findings for urban policy and crime prevention in the Catalan capital are discussed.

    Abstract The classical theory of random electric fields and polarization formalism has been formulated considering the Stokes parameters' auto-correlations. However, in this work, the need to consider the Stokes parameters' cross-correlations to obtain a complete description of the polarization dynamics of a light source is explained. We propose a general expression for the Stokes parameters' degree of correlation using both auto-correlations and cross-correlations, which we derive from the application of Kent's distribution in the statistical study of Stokes parameter dynamics on Poincaré's sphere. Additionally, from the proposed degree of correlation, we obtain a new expression for the degree of polarization (DOP) in terms of the complex degree of coherence, which is a generalization of the well-known Wolf's DOP. The new DOP is tested using a depolarization experiment in which partially coherent light sources propagate through a liquid crystal variable retarder. The experimental results show that our generalization for the DOP improves the theoretical description of a new depolarization phenomenon that Wolf's DOP cannot describe.

    Abstract Acute stress has been shown to modify hypothalamus-pituitary-gonadal (HPG) axis activity. Corticotropin-releasing hormone (CRH), the principal regulator of the hypothalamus-pituitary-adrenal (HPA) axis, has been implicated as a mediator of stress-induced effects on the reproductive axis. The role of the specific CRH receptor subtypes in this response is not completely understood. In the current study, we investigated the role of the CRH-R(1) receptor on luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), progesterone (P) and corticosterone (CT) secretion in stress-induced responses under the influence of estrogen (E(2)). Estrogen-primed ovariectomized rats (estradiol cypionate, 10 μg sc) received an i.v. administration of antalarmin (0.1 or 1mg/kg), a selective CRH-R(1) antagonist, or vehicle before restraint stress for 40 min. Seven blood samples were collected from two experimental groups (one from 10:00 h to 14:00 h and the other from 10:00 h to 18:00 h). An increase of plasma LH induced by restraint acute-stress was followed by alteration of the secretion pattern in the estrogen-induced afternoon surge. In a similar manner, we observed a suppression of the afternoon surge in plasma FSH, a delay of E(2)-induced PRL secretion, and an increase in plasma P and CT. Antalarmin attenuated stress-induce LH increase, decreased CT and P secretion and blocked the stress effects on PRL secretion. These findings suggest that CRH-R(1) mediates, at least in part, the restraint stress effects on the HPA, PRL, and reproductive axes.

    Abstract In insects, the sexually dimorphic body size, color, and horns are very conspicuous. Other not so obvious characteristics, such as behavioral traits related to reproduction, are also dimorphic (courtship dances and sounds). Among these, the stridulation, stridulatory apparatus, and hearing systems could also be different between sexes. Passalids are subsocial beetles with acoustic communication in the interactions of larvae-adult and adult-adult. Most of the species do not have morphological traits with sexual dimorphism, but sounds are dimorphic under reproductive and aggression contexts. We studied sexual dimorphism in the stridulation organs (plectrum) in Vindex agnoscendus (Percheron) as an important step towards understanding its functioning. We acquired SEM micrographs of the plectrum for 14 specimens per sex, for measuring size, density and shape of the spines. We performed traditional and geometric morphometric analyses to test for sexual differences in the spines of three zones (Z1-Z3) of the plectrum. Allometric analyses showed spine variation is not related to body size in either sex. Our univariate and multivariate analyses uncovered sexual dimorphism in spine size (length and width of spines), spine density (distance between spines and number of spines), and spine shape (landmark coordinates). Spines were wider in males than in females in the apical zone (Z1). The spines were further apart in females than in males in two zones (Z1, Z2) and the spine numbers were higher in females than in males in the apical zone (Z1). The shape of spines was different between sexes in two zones (Z1, Z2). Moreover, our disparity analyses showed different variability patterns in size and density of spines. Variability of spine shape was similar between sexes, and variability of spine density was higher in females than in males, while for spine size it was higher in males than in females. These findings for the plectrum suggest further research for sexual dimorphism in the pars stridens and acoustic signals, and for the possible roles of natural and sexual selection in the patterns of variability of spines.

    Abstract ZnO nano- and microstructures doped with K were grown by the Vapor-Solid method. Wires and needles are the main morphology observed, although some structures in the form of ribbons and triangular plates were also obtained. Besides these, ball-shaped structures which grow around a central wire were also detected. Raman and cathodoluminescence investigations suggest that variations in morphology, crystalline quality and luminescence emissions are related to the different lattice positions that K occupies depending on its concentration in the structures. When the amount is low, K ions mainly incorporate as interstitials (K

    Abstract Unmanned Aerial Vehicle (UAV) thermal imagery is rapidly becoming an essential tool in precision agriculture. Its ability to enable widespread crop status assessment is increasingly critical, given escalating water demands and limited resources, which drive the need for optimizing water use and crop yield through well-planned irrigation and vegetation management. Despite advancements in crop assessment methodologies, including the use of vegetation indices, 2D mapping, and 3D point cloud technologies, some aspects remain less understood. For instance, mission plans often capture nadir and oblique images simultaneously, which can be time- and resource-intensive, without a clear understanding of each image type's impact. This issue is particularly critical for crops with specific growth patterns, such as woody crops, which grow vertically. This research aims to investigate the role of nadir and oblique images in the generation of CWSI (Crop Water Stress Index) maps and CWSI point clouds, that is 2D and 3D products, in woody crops for precision agriculture. To this end, products were generated using Agisoft Metashape, ArcGIS Pro, and CloudCompare to explore the effects of various flight configurations on the final outcome, seeking to identify the most efficient workflow for each remote sensing product. A linear regression analysis reveals that, for generating 2D products (orthomosaics), combining flight angles is redundant, while 3D products (point clouds) are generated equally from nadir and oblique images. Volume calculations show that combining nadir and oblique flights yields the most accurate results for CWSI point clouds compared to LiDAR in terms of geometric representation (R
