    Stressors, job resources, fear of contagion, and secondary traumatic stress among nursing home workers in face of the COVID-19: the case of Spain

    Full text link
    This study aimed to analyze the psychological consequences of the COVID-19 pandemic on nursing home workers, as well as the influence of certain related stressors and job resources. Two-hundred twenty-eight nursing home workers in Spain participated in this cross-sectional study. High levels of workload, social pressure from work, contact with suffering, and fear of contagion were found. In nursing homes where cases of COVID-19 had been detected, workers experienced higher levels of secondary traumatic stress. Social pressure from work, high doses of exposure to suffering, lack of personnel and personal protective equipment, and minimal supervisor support were significant in explaining traumatic stress. Supervisor and coworker support moderated some of these relationships. The results are discussed in terms of the need to implement urgent psychosocial protection strategies and to provide personal protective equipment (PPE) to help prevent future psychological disorders in this worker population

    Overwhelmed by emotional job demands in high vigor days! Its detrimental effects on daily recovery from work among health-care workers

    Full text link
    The objective of this study is twofold: first, to analyze whether the daily level of energy in terms of vigor at work could explain the way in which workers psychologically detach from their work, relax, practice challenging activities, and have the feeling of having control over their leisure time when arriving home. Second, to check if the daily emotional job demands could hinder that relationship, reversing the positive effect of vigor in recovery. For this purpose, a multilevel study with a diary methodology was designed. In total, 94 nurses from various hospital and primary care centers in Madrid and Basque Country (Spain) participated in this study. They completed daily questionnaires twice a day (in the afternoon after work and at night before going to bed) for five consecutive workdays from Monday to Friday (N = 94*5 = 470). The results revealed that on days that vigor at work was high, nurses experienced more psychological detachment, relaxation, feelings of mastery, and time control at home. Moreover, on days that emotional job demands were high, vigor was more negatively related to psychological detachment and time control at home. Additionally, vigor was more positively related to all recovery experiences at home in days that emotional demands were low. Therefore, daily vigor can act as an energy resource that helps the worker to recover. However, this effect can occur in situations in which stressors are not present in high intensity. These results have clear practical implications for both health organizations and workers.This work was supported by I+D+I National Project of the Ministerio de Ciencia e Innovación (PID2019-106368GB-I00) AEI/10.13039/50110001103

    La publicidad de los actos jurisdiccionales electorales: entre la ponderación, la argumentación y la prudencia

    Get PDF
    Los tribunales electorales tienen un objetivo de pacificación social; pues se trata de salvaguardar la legitimidad de una determinada forma de organización socio-política. En este sentido, su responsabilidad es cumplir con el principio de transparencia y publicidad como forma de rendición de cuentas y vinculo necesario con quienes recurren a sus servicios. Por ello, y dado el interés político que revisten sus actividades, es deseable establecer parámetros mínimos respecto a la forma de comunicación de los juzgadores electorales con la ciudadanía, lo cual involucra, en su análisis. la búsqueda de equilibrio entre: la ética judicial, transparencia, derecho a la información, rendición de cuentas y libertad de expresión. Este equilibrio se logra bajo los presupuestos del discurso, la ponderación y la argumentación; estructuras previas que posibilitan justificar la excepcionalidad de la secrecía judicial como regla general en el proceso de comunicación previa a la existencia de la cosa juzgada. Ante esto, la trilogía presupuestal propuesta utilitaria sirve como herramienta para determinar los límites del juzgador electoral en la comunicación de sus proyectos de sentencia, previo a su discusión colegiada

    Optimal Location and Sizing of Distributed Generators in DC Networks Using a Hybrid Method Based on Parallel PBIL and PSO

    Get PDF
    This paper addresses the problem of the locating and sizing of distributed generators (DGs) in direct current (DC) grids and proposes a hybrid methodology based on a parallel version of the Population-Based Incremental Learning (PPBIL) algorithm and the Particle Swarm Optimization (PSO) method. The objective function of the method is based on the reduction of the power loss by using a master-slave structure and the consideration of the set of restrictions associated with DC grids in a distributed generation environment. In such a structure, the master stage (PPBIL) finds the location of the generators and the slave stage (PSO) finds the corresponding sizes. For the purpose of comparison, eight additional hybrid methods were formed by using two additional location methods and two additional sizing methods, and this helped in the evaluation of the effectiveness of the proposed solution. Such an evaluation is illustrated with the electrical test systems composed of 10, 21 and 69 buses and simulated on the software, MATLAB. Finally, the results of the simulation demonstrated that the PPBIL–PSO method obtains the best balance between the reduction of power loss and the processing time

    Trigger efficiencies of a proposed beam monitoring detector (BeBe) for p+p collisions at NICA energies

    Full text link
    The Multipurpose Detector (MPD) consists of a typical array of sub-detectors to study the nuclear matter originating from the collisions of beams provided by the Nuclotron-based Ion Collider fAcility (NICA). A beam monitoring detector~(BeBe) is proposed for stage 2 of MPD to increase the trigger capabilities. BeBe is constituted of two plastic scintillator disks segmented in 80 cells ± 2 m\pm~2~m away from the interaction point of MPD. Laboratory measurements to obtain the energy resolution of an individual BeBe cell prototype are presented. It is shown that an energy resolution of 22±6%22\pm6\% can be obtained. Based on Monte Carlo simulations, the trigger efficiencies of the BeBe are presented for p+p collisions at 11~GeV considering a threshold in the energy loss of the charged particles reaching the detector

    A Discrete-Continuous PSO for the Optimal Integration of D-STATCOMs into Electrical Distribution Systems by Considering Annual Power Loss and Investment Costs

    Get PDF
    Currently, with the quick increase in global population, the energetic crisis, the environmental problematic, and the development of the power electronic devices generated the need to include new technologies for supporting and potentiating electrical distributions systems; Distribution Static Compensators (D-STATCOMs) are highly used for this task due to the advantages that this technology presents: reduction in power loss, operation costs, and chargeability of branches, among others. The possibility to include this kind of technology within the electrical system has shown the need to develop efficient methodologies from the point of view of quality solution, repeatability and processing times by considering operation and investment costs as well as the technical conditions of the electrical grids under a scenario of variable power demand and then representing the real operation of the electrical grid. With the aim to propose a solution for this requirement, this paper presents a new Discrete-Continuous Particle Swarm Optimization (DCPSO) algorithm to solve the problem of the optimal integration of D-STATCOMs into Electrical Distribution Systems (EDSs). In this case, the objective function is the minimization of annual operating costs by using a weighted mono-objective function composed of the annual power loss and the investment cost and by including all constraints associated with the operation of an EDS in a distributed reactive compensation environmentinside the mathematical formulation. In order to evaluate the effectiveness and robustness of the proposed solution method, this study implemented two tests systems (i.e., 33- and 69-bus), as well as four comparison methods, and different considerations related to the inclusion of D-STATCOMs in the EDSs. Furthermore, for evaluating the repeatability of the solution obtained by each solution methods used, each algorithm was executed 100 times in Matlab software. The results obtained demonstrated that the proposed DCPSO/HSA methodology achieved the best trade-off between solution quality and processing time, with low standard deviation values for EDSs of any size

    Research background. Soursop nectar contains antioxidants and is preserved by pasteurization. However, this technology impairs its physicochemical properties and bioactive compounds. An alternative is therefore thermoultrasound, which could counteract these effects. The thermosonicated nectar was compared with a pasteurized one and the in vitro bioaccessibility of antioxidants was estimated. Experimental approach. The soursop nectar (25 %) was processed and the response surface methodology was used to determine the optimal conditions for thermoultrasound treatment (TUS). The TUS (75–90 % amplitude, 3.15–15 min) was applied, and 2 % stevia and 6 % agave inulin were added as sweeteners. The microbiological, physicochemical, enzymatic and antioxidant properties were analyzed. The properties of thermosonicated nectar obtained under optimal conditions were compared with pasteurized nectar. In addition to the above determinations, microstructure, total dietary fiber (TDF) and in vitro bioaccessibility of antioxidants were determined. Results and conclusions. The response variables that fit the mathematical model were L*, b*, chroma (C*), total phenolic content (TPC) and antioxidant activity determined by ABTS•+, DPPH˙ and Fe(III) reducing antioxidant power (FRAP). The L* and DPPH˙ were affected by quadratic time and TPC by time (p<0.0001). The optimum TUS condition was 82 % amplitude for 9.15 min and the responses variables were L*, b* and C* (45.48, 3.55 and 3.62, respectively), TPC expressed as gallic acid equivalents (38.40 mg/100 mL), ABTS•+ expressed as Trolox equivalents (TE) (31.28 μmol/100 mL), DPPH˙ expressed as TE (124.22 μmol/100 mL) and FRAP expressed as Fe(II) (3.06 μmol/100 mL). Compared to the pasteurized sample, thermosonicated sample had high values of L* (45.56), h° (-56.49), TPC (26.63 mg/100 mL), ABTS•+ and DPPH˙ (22.03 and 129.22 μmol/100 mL, respectively), FRAP (3.10 μmol/100 mL) and low pectin methylesterase (PME) activity (0.28 U/mL). For in vitro bioaccessibility, thermosonicated nectar showed high absorption of TPC (15.26/100 mL) and high antioxidant activity determined by ABTS (34.92 μmol/100 mL) and FRAP (7.88 μmol/100 mL). Novelty and scientific contribution. The thermoultrasound improves the physicochemical properties and in vitro bioaccessibility of antioxidants in soursop nectar. On the other hand, as an alternative, this beverage offers low-calorie alternative with prebiotic properties that benefits consumer health.Pozadina istraživanja. Nektar graviole sadržava antioksidanse, a radi produljenja roka trajanja tretira se pasterizacijom. Međutim, taj postupak narušava fizikalno-kemijska svojstva nektara i smanjuje količinu biološki aktivnih tvari u njemu. Stoga se kao alternativna metoda koristi kombinacija obrade toplinom i ultrazvukom. U radu smo usporedili svojstva nektara obrađenog toplinom i ultrazvukom s onima pasteriziranog uzorka te ispitali biološku raspoloživost antioksidansa in vitro. Eksperimentalni pristup. Obrađen je nektar graviole (s 25 % voćnog soka), a metodom odzivnih površina određeni su optimalni uvjeti obrade toplinom i ultrazvukom. Primijenjen je ultrazvuk amplitude 75-90 % tijekom 3,15–15 min, a kao zaslađivači su dodani 2 % stevije i 6 % inulina iz agave. Ispitana su mikrobiološka, fizikalno-kemijska, enzimska i antioksidacijska svojstva. Svojstva nektara dobivenog obradom toplinom i ultrazvukom pri optimalnim uvjetima uspoređena su s onima pasteriziranog uzorka. Osim toga, određeni su mikrostruktura, ukupna količina prehrambenih vlakana i in vitro biološka raspoloživost antioksidansa. Rezultati i zaključci. Varijable koje su odgovarale matematičkom modelu bile su L*, b*, zasićenost boje (C*), ukupni udjel fenola i antioksidacijska aktivnost određena metodama ABTS˙+, DPPH˙ i FRAP. Na vrijednost L* i sposobnost uklanjanja DPPH˙ utjecali su kvadratna vrijednost vremena te interakcija ukupnog udjela fenola i vremena (p<0,0001). Optimalni uvjeti obrade toplinom i ultrazvukom bili su amplituda 82 % tijekom 9,15 min, a odzivne varijable bile su L* (45,48), b* (3,55 ) i C* (3,62), ukupni udjel fenola izražen u ekvivalentima galne kiseline (38,40 mg/100 mL), sposobnost uklanjanja ABTS˙+ izražena u Trolox ekvivalentima (TE) (31,28 μmol/100 mL), sposobnost uklanjanja DPPH˙ izražena u TE (124,22 μmol/100 mL) i FRAP izražen kao Fe(II) (3,06 μmol/100 mL). U usporedbi s pasteriziranim uzorkom, dobiveni je nektar imao velike vrijednosti L* (45,56), h° (–56,49), ukupnog udjela fenola (26,63 mg/100 mL), dobru sposobnost uklanjanja ABTS˙+ (22,03 μmol/100 mL) i DPPH˙ (129,22 μmol/100 mL), veliku vrijednost FRAP (3,10 μmol/100 mL), a malu aktivnost metil esteraze (0,28 U/mL). Ispitivanje in vitro bioraspoloživosti antioksidansa pokazalo je da dobiveni nektar ima veliku biorapoloživost ukupnog udjela fenola (15,26/100 mL) i izraženu antioksidacijsku aktivnost, određenu pomoću ABTS (34,92 μmol/100 mL) i FRAP (7.88 μmol/100 mL) metoda. Novina i znanstveni doprinos. Obradom toplinom i ultrazvukom poboljšana su fizikalno-kemijska svojstva i in vitro biološka raspoloživost antioksidansa iz nektara graviole. Dobiveni napitak može poslužiti kao niskokalorična alternativa s prebiotičkim svojstvima i pozitivnim učinkom na zdravlje korisnika
