Teletrabajo y rendimiento laboral en los servidores de la sede central del Instituto Nacional Penitenciario 2021

El presente estudio tuvo el objetivo determinar la relación entre el teletrabajo y rendimiento laboral en los servidores de la sede central del Instituto Nacional Penitenciario 2021, enmarcado en una crisis generalizada a causa de la COVID19, llevando las instituciones a su modernización en infraestructura para que los trabajadores puedan realizar teletrabajo. Esta investigación es de tipo básica con un enfoque cuantitativo, diseño no experimental de tipo correlacional. Se utilizó un muestreo probabilístico compuesto por teletrabajadores. Se emplearon dos cuestionarios, obteniendo un Alfa de Cronbach fue de 0,863 y procesados mediante Microsoft Excel y el programa SPSS. Como resultados de la investigación del estadístico no paramétrico de correlación del Rho de Spearman sobre las variables del teletrabajo y el rendimiento laboral (RL) con un “p” valor de 0,000<0,01, y una correlación de Rho de Spearman de 0,748. Asimismo, como resultados de cultura organizacional y RL obtuvimos una correlación de Rho de Spearman de 0,654; herramientas tecnológicas y RL de 0,363; optimización de procesos y RL de 0,523; y finalmente capacitación y RL de 0,557. Finalmente, se rechazaron todas las hipótesis nulas y se aceptaron las hipótesis alternas, por lo cual, se infirió que todas las relaciones son directas y positivas. En ese contexto, se planteó una serie de recomendaciones que permitirán mejorar el teletrabajo y rendimiento laboral para que esta modalidad sea una alternativa viable y pueda servir de referencia para futuras investigaciones

Pixel, Partition, Persona: Machine Vision and Face Recognition in Kazuo Ishiguro’s Klara and the Sun

This article examines the relationship between machine vision, face recognition and affect in Kazuo Ishiguro’s speculative fiction novel Klara and the Sun (2021). It explores the ways that Ishiguro’s novel enacts, stages, and dramatises cognitive and emotional acts of comprehension and empathy through ‘face reading’. The article takes up Guillemette Bolen’s theorisation of ‘kinesic imagination’ and Sianne Ngai’s concept of ‘ugly feelings’ to investigate the affective and representational dilemmas of technological face recognition in speculative fiction. Through the careful treatment of literary language, itself a complex response to rapidly evolving technology, Klara and the Sun presents instances of affective subtlety, hesitation, ambiguity, mutability, confusion and deficit to solicit an emotional response in the reader concerning the sociotechnical reception and future possibilities of machine vision and facial recognition technologies. In this way, Ishiguro’s novel offers a timely challenge to the algorithmic design principles of face-recognition technology due to its complex affective (rather than purely categorical) treatment of both human and non-human faces

Evaluation of the Performance Characteristics of the Lightning Imaging Sensor

The Lightning Imaging Sensor (LIS) that was on board the Tropical Rainfall Measuring Mission (TRMM) satellite captured optical emissions produced by lightning. In this work, we quantify and evaluate the LIS performance characteristics at both the pixel level of LIS events and contiguous clusters of events known as groups during a recent 2-yr period. Differences in the detection threshold among the four quadrants in the LIS pixel array produce small but meaningful differences in their optical characteristics. In particular, one LIS quadrant (Q1, X >= 64; Y >= 64) detects 15%-20% more lightning events than the others because of a lower detection threshold. Sensitivity decreases radially from the center of the LIS array to the edges because of sensor optics. The observed falloff behavior is larger on orbit than was measured during the prelaunch laboratory calibration and is likely linked to changes in cloud scattering pathlength with instrument viewing angle. Also, a two-season comparison with the U.S. National Lightning Detection Network (NLDN) has uncovered a 5-7-km north-south LIS location offset that changes sign because of periodic TRMM yaw maneuvers. LIS groups and flashes that had any temporally and spatially corresponding NLDN reports (i.e., NLDN reported the radio signals from the same group and/or from other groups in the same flash) tended to be spatially larger and last longer (only for flashes) than the overall population of groups/flashes.NASA [80MSFC17M0022]; NASA ROSES-2014 program [NNH14ZDA001N-WEATHER]6 month embargo; published online: 6 June 2019This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Immunomodulatory properties of ethanol extract of Canarium ovatum (Burseraceae) pulp

Purpose: To evaluate the immunomodulatory properties of ethanol extract of the pulp of Canarium ovatum (COPE).Methods: The immunomodulatory activity of ethanolic extract of the pulp of C. ovatum was investigated in vivo using Balb/C mice. Extract doses of 300 and 600 mg/kg were orally administered to study its effect on delayed type hypersensitivity and humoral antibody response using sheep red blood cells (SRBC). Acute oral toxicity profile and phytochemical analysis were also determined.Results: Orally -administered COPE did not exhibit any mortality or signs of toxicity at doses 300 - 2000 mg/kg. Phytochemical analysis revealed the presence of biologically-active compounds such as sterols, triterpenes, flavonoids, alkaloids, saponins, glycosides and tannins. Treatment with COPE for 7 days stimulated the early phase of DTH response through significant increase in foot pad thickness (111.87 ± 9.97 % at 300 mg/kg, and 91.27 ± 7.81 % at 600 mg/kg), when compared to distilled water and cyclophosphamide (CP) groups. Similarly, COPE significantly enhanced antibody titer, with highest titer at the dose of 300 mg/kg. Histological observations of the spleen showed follicles with active germinal centers and proliferating lymphocytes, which are consistent with the immunostimulatory effects of COPE.Conclusion: These results show that COPE has stimulatory effects on cellular and humoral responses in mice, indicating its potential as an immunostimulatory agent.Keywords: Immunomodulation, Canarium ovatum, Delayed-type hypersensitivity reaction, Antibody titer, Pili pul

Phase Equilibration and Magnetic Field Generation in U(1) Bubble Collisions

We present the results of lattice computations of collisions of two expanding bubbles of true vacuum in the Abelian Higgs model with a first-order phase transition. New time-dependent analytical solutions for the Abelian field strength and the phase of the complex field are derived from initial conditions inferred from linear superposition and are shown to be in excellent agreement with the numerical solutions especially for the case where the initial phase difference between the bubbles is small. With a step-function approximation for the initial phase of the complex field, solutions for the Abelian field strength and other gauge-invariant quantities are obtained in closed form. Possible extensions of the solution to the case of the electroweak phase transition and the generation of primordial magnetic fields are briefly discussed.Comment: LaTeX, 41 pages, 6 figures, submitted to Physical Review
