Published: January 2023

The contribution focuses on the issue of teacher authority and classroom climate. Our research aimed to determine a relationship between teacher authority built on the teacher’s interaction style and dimensions constituting the classroom climate. The research involved n = 411 students who assessed the interaction style of their teachers (n = 23). The Questionnaire on Teacher Interaction (QTI) and Classroom Environment Scale (CES) were employed. Analysis of empirical data showed a statistically significant positive relationship between the interaction style-built teacher authority and classroom climate dimensions. The statistically significant positive relationship was between the interaction style dimensions: helpful, understanding, student responsibility and the classroom climate dimensions: involvement, task orientation, organisation and order, and rule clarity. A statistically negative relationship was found between the interaction style dimensions: uncertain, dissatisfied, admonishing and the classroom climate dimensions: teacher support, organisation and order, and rule clarity. According to our findings, authoritative teachers, perceived by students as good organisers, helpful, understanding, and giving responsibility, can create a positive climate in classrooms.

Education for pre-service teachers should focus on developing the competencies necessary to understand and practice learners’ cognitive and emotional characteristics. In this study, after applying the competency programme for understanding and guiding students with learning difficulties to pre-service teachers, the effects of the programme on teacher efficacy, teaching passion, and empathy were verified. As a result, it was found that participating in the experimental group to which the competency programme was applied was more effective than the control group in enhancing teacher efficacy, teaching passion, and empathy of pre-service teachers, and discussion and suggestions were provided.

Authors:   University of Kragujevac, Jagodina, Serbia, Živković Predrag
Published: January 2023

The research aimed to determine significant relationships between selected dimensions of professional life and the work of part-time teachers in a sample of respondents in the Republic of Serbia. In testing the model on a sample from the TALIS 2013 (Teaching and Learning International Survey), which consisted of dimensions of professional development (general and specific), barriers to professional development, evaluation and job satisfaction, showed statistically significant relationships between feedback, specific needs of professional development, and less significant links between the general needs of professional development and the barriers to this development with job satisfaction. Quantitative methods were followed to report the results of the cross-sectional study. Partial least square structural equation modelling (PLS-SEM) was utilised to assess the quantitative data. Research with this sample of surveyed teachers has not been done so far.

The study assessed whether students who contracted COVID-19 and did not fall ill differed in coping strategies. The study comprised 111 participants, including 55.9% who were infected and 44.1% who were not. It consisted of online (49.5%) and blended mode learners (50.5%) aged 19 to 31. We used the Brief COPE Inventory to assess ways of coping with stress. Among online students, 65.5% fell ill, while less than half of blended mode learners got sick. Students who contracted COVID-19 were more likely to use maladaptive coping strategies, and respondents who did not become ill were more likely to use adaptive strategies.
I Can See Positive Aspects of Online Education. Educators’ Well-Being and Challenges Faced During the COVID-19 Pandemic
Authors:   Warsaw University, Warsaw, Poland, Skura Monika , Steinhagen Anna ,   Psychological and Pedagogical Counseling Center No. 16, Warsaw, Poland
Published: January 2023

The emergence and rapid spread of SARS-CoV-2 caused uncertainty about our health, jobs, and the education system. For teachers, changes in workplaces and the breakdown of interpersonal relationships during the pandemic caused even greater stress levels in what is already known to be a stressful job. We wanted to find out if a positive or negative attitude towards online work influenced levels of stress and mental well-being, perceived difficulties at work, subjective evaluation of received support, and effectiveness of remote work during the first wave of SARS-CoV-2 in Poland. Data was collected using a questionnaire, the PSS 10 scale and another scale based on GHQ12 and GH30. Nearly one-third of the respondents indicated positive aspects of online education. Those who could see the positive aspects of online education showed themselves better adapted to the new form of working and had higher results in all four scales that we researched. They handled online tools, used synchronous methods, conducted educational activities more often, and felt competent during online work. Supporting the effectiveness of educators by improving the competencies that they need for this new form of working is vital with regard to the changes within the school institution.
Robust Control for Dynamical Systems with Non-Gaussian Noise via Formal Abstractions
Authors: Badings Thom , Romao Licio , Abate Alessandro , Parker David , Poonawala Hasan A. , Stoelinga Marielle , Jansen Nils
Published: January 2023

Controllers for dynamical systems that operate in safety-critical settings must account for stochastic disturbances. Such disturbances are often modeled as process noise in a dynamical system, and common assumptions are that the underlying distributions are known and/or Gaussian. In practice, however, these assumptions may be unrealistic and can lead to poor approximations of the true noise distribution. We present a novel controller synthesis method that does not rely on any explicit representation of the noise distributions. In particular, we address the problem of computing a controller that provides probabilistic guarantees on safely reaching a target, while also avoiding unsafe regions of the state space. First, we abstract the continuous control system into a finite-state model that captures noise by probabilistic transitions between discrete states. As a key contribution, we adapt tools from the scenario approach to compute probably approximately correct (PAC) bounds on these transition probabilities, based on a finite number of samples of the noise. We capture these bounds in the transition probability intervals of a so-called interval Markov decision process (iMDP). This iMDP is, with a user-specified confidence probability, robust against uncertainty in the transition probabilities, and the tightness of the probability intervals can be controlled through the number of samples. We use state-of-the-art verification techniques to provide guarantees on the iMDP and compute a controller for which these guarantees carry over to the original control system. In addition, we develop a tailored computational scheme that reduces the complexity of the synthesis of these guarantees on the iMDP. Benchmarks on realistic control systems show the practical applicability of our method, even when the iMDP has hundreds of millions of transitions.

Authors: Parambil Farhad Vayadi , Yusuf Akkara
Published: January 2023

Western ghats (Biodiversity hotspot) of Kerala is abundant in cyanobacterial species diversity. The cyanobacterial genus Nostoc inhabits on natural rock surfaces, thus play an important role in terrestrial ecosystems by colonizing in new and unsettled ecological niches. The abiotic factors like temperature, pH, humidity, micro and macro nutrients contribute to the abundance of Nostoc spp. on the rock surface. Nostoc spp. act as a potential candidates for eco-friendly and sustainable agriculture. Even though, their substantial importance to the environment most of the Nostoc spp. are unexplored, especially from Western ghats region of Kerala. Hence, the present study investigated the diversity of epilithic Nostoc spp. from Western ghats regions of Kerala. A total of 25 epilithic Nostoc spp. were identified in this study. Among the 25 species, Nostoc tibeticum and N. indistinguindem are new records from India.
The Fourth Industrial Revolution has arrived. Comments on Moll (S Afr J Sci. 2023;119(1/2), Art. #12916)
Authors: Marwala Tshilidzi
Published: January 2023

This Commentary is a response to Moll (S Afr J Sci. 2023;119(1/2), Art. #12916) who refutes the Fourth Industrial Revolution (4IR) and its impact. As this Commentary demonstrates, there is a case to be made that the 4IR constitutes a revolution and that the limitation at the level of pure technology can be refuted as a revolution is based on its wider impact. While the 4IR can be classified as an evolution of the Third Industrial Revolution, its scale, scope and complexity denote a revolution of its own.

Published: January 2023

Background: Some studies have evaluated the role of QRS duration (QRSd) as predictor of response to Cardiac Resynchronization Therapy (CRT). However, their results are still not entirely clear. The goal of our study was to determine the correlation between the relative change in QRS narrowing index (QI) compared to clinical outcome and prognosis in patients who underwent CRT implantation. Methods: We collected clinical and echocardiographic data of 115 patients in whome a CRT device was implanted in accordance with current guidelines. QRS duration before and after CRT implantation and QI were measured. Results: After 6 months, a significant improvement in all echocardiographic parameters was detected. QI was correlated to reverse remodelling (r = +0.19; 95% CI: 0.006 to 0.35, p = 0,049). The value of QI that predicted best LV reverse remodelling after 6 months of CRT was 12.25% (sensitivity = 65,5%, specificity = 75%, area under the curve = 0.737, p = 0,001). Independent predictors of QI are sex, serum creatinine and eGFR measured at baseline and LVEF pre-CRT performed by echocardiography. We observed an betterment in their HF clinical composite score and NYHA class at 12 months. We have also investigated the clinical outcomes and the possible sex differences related to QI. Conclusions: Patients with a larger QI after CRT initiation showed greater echocardiographic reverse remodelling and better outcome from death or cardiovascular hospitalization. QI seems to be an easy-to- measure variable that could be used or evaluated to predict CRT response but further studies are needed.
Two methods for determining combinatorial identities
Authors: Victor Kowalenko
Published: January 2023

Two methods are presented for determining advanced combinatorial identities. The first is based on extending the original identity so that it can be expressed in terms of hypergeometric functions whereupon tabulated values of the functions can be used to reduce the identity to a simpler form. The second is a computer method based on Koepf's version of the Wilf-Zeilberger approach that has been implemented in a suite of intrinsic routines in Maple. As a consequence, some new identities are presented.

PRE-SPLIT PERFORMANCE EVALUATION
Authors: Hemed Ahmed , Ouadif Latifa
Published: January 2023

In order to improve conveying and crusher throughput performance, major open pit mines are increasingly using high energy blasting. Strict and effective controlled blasting methods are required to protect the integrity of the pit walls from the increasing energy concentration. The M’haoudatt mine lacks pre-split procedures, which has led to unstable slopes and landslides that have increased the strip ratio. In order to correct mining anomalies, this work intends to evaluate pre-split practice. The aim of the work is to evaluate the pre-split performance in the M’haoudatt mine through tests carried out on one of the pit benches.
A LINDBLADIAN OPERATOR FOR OPEN SYSTEM THERMALIZATION, WITH APPLICATIONS
Authors: Englman R.
Published: January 2023

A general phenomenological expression is provided, within the frame of the Gorini-Kossakowski-Sudarshan-Lindblad formalism, for the time (t) development of the density operator ρ(t) during thermalization, namely the process such that an open system with arbitrary initial states, when coupled to a thermal bath, ρ (t -> ∞) takes up a Gibbsian form. The theory is applied to a molecular vibrating system, to a semi-classical vibronic entity, and may be applied to the excitation probabilities in a condensed state’s phonon system and to arbitrarily large-scale systems (reaching as far as global warming). A sideline is to an entropy-decreasing Maxwell-demon type quantum state transition. While the prescription may not be unique, it gives rise to an experimentally testable non-monotonicity in the system’s information entropy. The calculated entropy maximum found for an electronic doublet is interpreted as a “transient democratization” of the states and, though lacking a formal proof, a conjecture is proposed for the occurrence of maxima in general instances.
MHD NANOFLUID FLOW PAST AN INCLINED PLATE WITH SORET AND DUFOUR EFFECTS
Authors: Palani G. , Arutchelvi A.
Published: January 2023

A steady incompressible nanofluid flow past an inclined permeable plate is numerically studied, including radiation, viscous dissipation, and Soret and Dufour effects. A coupled non-linear simultaneous differential similarity equation is created by non-dimensionalizing the ruling partial differential equations. Then, nonlinear coupled equations with transformed boundary conditions are resolved by the shooting method based on the Runge-Kutta fourth-order method. The Prandtl number, Grashof number, Schmidt number, magnetic parameter, and Soret and Dufour effects are just a few of the controlling flow parameters for which computations are done. Graphs are used to illustrate how various flow factors affect momentum, energy, and concentration equations. The impacts of these variables on skin friction coefficients, Nusselt number, and Sherwood number are given in tabular form. The concentration profile increases with the Soret number and the reverse trend is observed with the Dufour number. It is further noted that heat-mass transfer rate reduces in the boundary layer due to an increase in the values of Soret or a decrease in the values of Dufour.

Published: January 2023

The purpose of the work was to study the psychological mechanisms of the formation of an intrapsychic response to chronic back pain. The hypothesis was the assumption that the internal image of the disorder in patients with chronic back pain differs depending on the subjective perception of pain. Operationalization of the internal image of disorder was carried out in accordance with a four-level concept (sensitive, motivational, emotional, and intellectual levels). Psychodiagnostic tools were used: "McGill's Pain Questionnaire (Kastiro I.V., 2012), "Restoration of the locus of control" questionnaire (Belova N.A., 2002), expert assessment of compliance on a five-point scale, "Psychological factors of attitude to illness and treatment" questionnaire (Rasskazova E.I., 2016). In total, 84 patients aged 54.5±14.4 years were examined, including 52 (61.9%) women and 32 (38.1%) men who were at the inpatient stage of medical rehabilitation for dorsopathies with moderate chronic pain syndrome. The pain has lasted for 12.9±13.4 years. As a result of the study, it was found that the groups of patients with mixed and nociceptive pain differ from each other in the structure of the internal image of the disorder: patients with mixed pain have no relationship between the motivational and emotional levels with the sensitive – the level of primary processing of sensory information.

Published: January 2023

The purpose of this study was to evaluate the experience of using the Peabody Picture Vocabulary tool to assess receptive vocabulary in preschoolers. The study involved 619 Russian-speaking children aged 3–7 years (M=67.80, SD=13.73), 48.3% of whom were boys. The Peabody Picture Vocabulary test-IV (form A) was used in the study. The article analyzed differences between children of different age groups from 3.5 to 7.5 years with a step of six months. It was found that there were significant differences in the ceiling items, the total number of errors, and the raw scores in children of different age groups. No gender differences were found. An analysis of the children's performance of series and individual tasks showed that the complexity of the tasks was unevenly distributed. As a result, the methodology in its current form does not work quite as it was intended by its creators: Moscow preschoolers go through a lot of series and spend a lot of time on the implementation of the methodology, which is due to differences in the lexical systems between Russian and English. In this regard, the tool is not optimal for use in its current form; the authors of the article propose to design a local tool for the assessment of the receptive vocabulary in Russian preschoolers.

Rapid Near-Field Attenuation of Ground Motion from Shallow Induced Earthquakes, Case Study: Preston New Road, United Kingdom
Authors: Suroyo Pungky M. , Edwards Benjamin
Published: January 2023

Ground motions from shallow induced earthquakes and tectonic seismicity were investigated in this study by directly modeling the seismic attenuation quality factor (Q) using spectral fitting and coda envelope decay methods. We use data from the Preston New Road (PNR) shale gas induced seismicity sequences near Blackpool, United Kingdom, in 2018 and 2019, in addition to regional tectonic events in the United Kingdom. Our results show that the local Q obtained from the induced seismic sequences at PNR, attributed to shallower layers in the crust, leads to a rapid rate of near-field decay (sudden loss in amplitude of earthquake signal over a short distances), with significantly stronger attenuation than observed for regional events. We furthermore find that estimates of Q are nonunique to a given record, differing both with the method and the analysis windows used, particularly at high frequency. These differences can be attributed to the different modeling methodologies (e.g., different assumptions) or to fundamental differences in physical attenuation processes within the seismic wavefield itself, which traverses multiple ray paths and comprises various phases. Our results indicate that to model ground motions for shallow earthquakes, it is important to consider the composite Q along a specific path rather than an average regional Q. To this extent, a depth-dependent attenuation model is considered crucial to bridge the gap between shallow induced earthquakes and tectonic seismicity.
Redefining Expectations for Migraine Prevention

With the advent of new preventive migraine treatments, such as calcitonin gene-related peptide inhibitor monoclonal antibodies, there is a need to ensure realistic treatment expectations, and to carefully consider therapeutic options. Current treatment guidelines suggest that reductions in mean monthly headache days of ≥50% from baseline should be considered evidence of treatment efficacy, although in some patients, benefits can be seen at lower thresholds. However, patients may expect greater reductions in migraine attacks, so setting realistic expectations is important for treatment success. As treatment side effects and a lack of efficacy are the main reasons for treatment discontinuation, possible side effects should be discussed, and the individual goals of patients considered. Current American Headache Society guidelines suggest candidacy for preventive migraine treatment is primarily based on the frequency of attacks in the USA, with treatment recommended for patients who have ≥4 migraine days per month. However, even fewer than 4 monthly headache days per month can have a severe impact on overall health-related quality of life in addition to impairment during individual episodes. Finally, the use of acute therapy should be carefully monitored and considered when treatment decisions are being made, to ensure optimization of use, and to avoid overuse and progression to chronic migraine. These considerations indicate that patient needs are multifaceted and that management decisions need to be crafted on a case-by-case basis.

“¿Las máquinas pueden pensar?”. Esta pregunta se la formuló Alan Turing1, considerado como el padre de la computación, ya en el año 1950 (Turing, 1950). Al mismo tiempo, formuló un pequeño juego al que acuñó el nombre de “juego de las imitaciones”. El juego consiste en que una persona A interactúa con una máquina B y una persona C, e intentará adivinar cuál de ellos es la máquina. A no tiene acceso visual ni sonoro a B ni a C: sólo se puede comunicar a través de una terminal con ambas. El nombre de “imitación” se refiere a que la máquina B intentará replicar el comportamiento de la persona C. Este juego ha pasado a conocerse como el Test de Turing, que además ha extendido la idea básica del juego de las imitaciones: ¿podemos distinguir entre una persona y una máquina, por ejemplo, durante una conversación por mensajes de texto? ¿Y durante una llamada telefónica? Puede que un día tengamos incluso que preguntarnos si podemos distinguir a una persona de un robot.
Biomineralización

Published: January 2023

Los sistemas bióticos y abióticos se entrelazan, en su máxima expresión, durante la formación de biominerales. Estos son minerales producidos por los organismos, ayudados de macromoléculas orgánicas, los cuales forman esqueletos y estructuras esqueléticas (como dientes, huesos, conchas, espículas…) de una manera precisa, que involucra una maquinaria celular sincronizada y que tienen una función biológica muy específica. El estudio de la biomineralización es multidisciplinar y tiene un enfoque diverso: ingeniería, biología, química, paleontología. Este artículo resume qué es la  biomineralización, cuándo aparece en la historia de la Tierra, tipos de biomineralización, el papel de la matriz orgánica en la biomineralización, los controles (genéticos y ambientales) de la biomineralización, así como el papel de los estudios sobre biomineralización empleando fósiles.
Estudiando los entresijos detrás de la grasa de la alubia
Authors: Gonzalo de la Rubia Alfonso
Published: January 2023

La provincia de León supone el 44,32% del total del área cultivada de esta leguminosa en España y el 49,12% de la producción nacional, lo que ha llevado a la creación del sello Indicación Geográfica Protegida (IGP) Alubia de La Bañeza-León, que agrupa a 4 variedades (Canela, Plancheta, Pinta y Riñón), de las cuales, la variedad Riñón ha sido el sujeto de estudio de esta tesis. Sin embargo, dicha producción se ve perjudicada por una enfermedad conocida como enfermedadde la grasa (o simplemente “la grasa”), producida por la bacteria Pseudomonas syringae pv. phaseolicola (Pph). Frente a esta patología de la alubia, cuyo agente causal describió Burkholder hace 100 años, seguimos sin contar con una solución eficaz, posiblemente por el hecho de que esta bacteria patógena sobreviva en la semilla, de manera que en la siguiente cosecha podrá volver a desencadenarse la enfermedad, aunque la proporción de semillas contaminadas sea muy baja.

Published: January 2023

Monitoring the quality of irrigation water can help in the maintenance of filters and irrigation systems, avoiding clogs and uniformity problems. The objective of this work was, thus, to evaluate the performance of sensor modules for monitoring irrigation water quality variables. For that, three sensors were evaluated, and their performance was rated from the adjustment of calibration equations, obtained through linear regression analysis (yi = b0 + b1xi + εi), using the ordinary least squares method (OLS) to estimate its parameters (β0 and β1). The first sensor evaluated was the Ph4502c for pH measurement. Direct methodology was used, using standard pH solutions (1.79; 4.5; 6.88; 12.13; and 13.99) and an electrode type BNC probe. The second evaluated sensor was turbidity model TSW30. To evaluate the total dissolved solids (TDS) sensor, the direct method was applied, using solutions with electrical conductivity of 0.50, 1.0, and 2.0 dS m-1. To investigate the assumptions of independence, homoscedasticity, and normality of the residuals of the linear regression models, the Durbin-Watson, Breusch-Pagan, and Kolmogorov-Smirnov tests were respectively used. In the evaluation of the statistical performance, the indicators of the root-mean-square error, coefficient of determination, correlation coefficient, confidence index, and index of agreement were adopted. The ordinary least squares method did not produce the best unbiased linear estimators for the calibration equations of the pH, turbidity, and TDS sensors, due to the violation of the regression assumptions. The adjustments showed good accuracy for water quality assessment, according to high performance statistics and models classified as ‘Excellent’.

El Estado debe ser garante de la seguridad ciudadana y del mantenimiento del orden público, como lo señala el artículo 2 de la Constitución, pero también debe velar por el cumplimiento de los derechos humanos en territorio y por los tratados y convenios internacionales que haya firmado o ratificado. El objetivo principal de este artículo es hacer un análisis de la responsabilidad internacional del Estado en el marco de la protesta social. En este sentido, se discute el derecho a la protesta social nacional e internacionalmente, la criminalización y los límites impuestos a este derecho, el papel que desempeñan los medios de comunicación y, finalmente, la responsabilidad del Estado por la acción u omisión de sus agentes en la limitación al ejercicio de esta protesta, así como la falta de políticas y su regulación. Mediante el análisis de fuentes y la revisión de datos, con base en el método analítico-sistemático, se consultan fuentes bibliográficas y documentales para tener un panorama más claro sobre este tema. El trabajo concluye que el Estado es responsable internacionalmente por la acción u omisión de sus agentes y, en este sentido, debe responder frente al hecho ocurrido en el marco de la protesta, en el entendido de las garantías internaciones y constitucionales que tiene este derecho autónomo.

De la pacificación a la paz territorial en el posacuerdo: heterotopía contrahegemónica de los DDHH
Authors: Hernández Villarreal Seuxis José
Published: January 2023

En este artículo se hace un análisis holístico de los fundamentos y la transformación del concepto de paz a la luz de los derechos humanos, en general, y de los derechos colectivos, en particular, para entender la mutación histórica a partir de dos conceptos: la pacificación de los territorios, con miras a la imposición de un orden de tipo hegemónico, y la paz territorial, que se expone como antítesis o elemento contrahegemónico, dejando en evidencia la clara participación simbiótica entre el concepto de paz, el territorio y los DDHH, con una visión de disfrute en esencia colectiva. Se contrastan fenómenos socio-jurídicos en el espectro colombiano actual del posacuerdo, junto con elementos dogmáticos y fenomenológicos de carácter histórico, que exponen como resultado la calidad heterotópica y contrahegemónica de los derechos humanos en Colombia, revestidos de una nueva fundamentación.

Published: January 2023

El propósito de este artículo científico es determinar un mecanismo de armonización interinstitucional para el control de los fenómenos de inseguridad derivados del flujo migratorio venezolano en territorio colombiano. Se validan los resultados a través de un diseño metodológico fundamentado en un enfoque cualitativo, en un tipo de investigación descriptiva y en un muestreo no probabilístico de tipo propositivo o intencional, aspectos que dieron lugar a la construcción y aplicación de entrevistas semiestructuradas y dos matrices de doble entrada: una de oportunidades y amenazas en el medio (POAM) y una de capacidad interna (PCI). Se concluye que Colombia no cuenta con una política clara para abordar temas fronterizos ni una instancia que realice seguimiento de manera sostenida a sus fronteras.
Derechos laborales de la mujer en el contexto digital en Colombia
Authors: Viveros Rengifo Daniela
Published: January 2023

En este artículo se muestra la forma como la mujer, a pesar de las dificultades que se le han presentado con las transformaciones socioculturales y socioeconómicas de las últimas décadas por el ingreso de forma masiva al mercado laboral, sigue ampliando su participación en la sociedad y en Estados contemporáneos, con un protagonismo inusitado, adecuándose a los desafíos tecnológicos y las crisis ambientales, sin descuidar sus múltiples roles como la atención del hogar, la maternidad, la asistencia a los padres y sus compañeros sentimentales, entre otras actividades que determinan mayor disposición horaria en actividades cotidianas que los hombres. Pese al avance en la vinculación laboral de la mujer en diversos campos económicos, teniendo en cuenta que era considerada sólo para labores domésticas y la crianza de sus hijos, se le vulneran sus derechos fundamentales, debido a que buena parte de ellas se encuentra en la informalidad, en la que la estabilidad laboral y la seguridad social son limitadas. Estas afectaciones en los derechos laborales recaen también en el núcleo familiar, como es el caso de las madres cabezas de familia. Este artículo también analiza el desempeño laboral de las mujeres respecto a las nuevas tecnologías en el contexto latinoamericano y el impulso de organizaciones internacionales y supraestatales como la OIT y la ONU, en el ámbito global, y en lo regional el Sistema Interamericano de Derechos por medio de la Corte IDH y la Comisión IDH para garantizar y proteger los derechos fundamentales laborales de las mujeres en Colombia y la región.
Aproximación a la historia de la sexualidad en el mundo occidental desde la modernidad
Authors: Martínez Hincapié Wilmar Alexánder
Published: January 2023

En este artículo se hace un análisis histórico de los aspectos teóricos y sociales más representativos de la sexualidad en occidente desde la modernidad, como base para entender de forma general los procesos y las dinámicas actuales de este tema, así como su importancia y repercusión social, política, de salud pública, económica y para el ejercicio de la ciudadanía. Este documento se construyó como parte de la investigación “Análisis de la producción académica sobre representaciones sociales de la sexualidad en Colombia 2000-2020” (2022), a partir de una revisión documental que incluyó libros, artículos de investigación de revistas indexadas y notas de prensa. El estudio se hizo con base en las disciplinas, campos del saber y orientaciones temáticas de dichos textos y a partir de los enfoques teóricos y metodológicos propuestos por los autores. Los principales resultados se enmarcan en la evolución teórica del concepto de sexualidad y en los cambios sociales, políticos y en materia de salud que se han gestado desde la modernidad y que se han traducido, principalmente en el siglo XX, en diversos movimientos que buscan la reafirmación de derechos, el reconocimiento del papel de la mujer en el desarrollo social, la inclusión de las poblaciones sexualmente diversas, como agentes activos, y las identidades de género como base para la igualdad.

Authors: Pérez Barrios Edgar Estuardo , Silva Alvarado Eduardo René
Published: January 2023

El presente trabajo de investigación corresponde al estudio de la situación del sector eléctrico en Guatemala como resultado al cambio de legislación a causa de la sanción de la Ley General de Electricidad, para lo cual se usa en enfoque cualitativo descriptivo. En la última década del siglo veinte, surgieron deficiencias en el suministro del servicio de energía eléctrica, debido a la insuficiente capacidad instalada en las etapas de  generación, transmisión, distribución y comercialización de energía eléctrica; para solucionar la problemática, se sanciona la Ley General de Electricidad, para promover la inversión privada, eliminar los monopolios y la administración vertical; por medio de fuentes de información secundarias se obtienen datos sobre capacidad instalada, demanda máxima y generación de energía eléctrica, al procesarlos y analizarlos, se observa el incremento de la capacidad instalada, de la demanda máxima y de la generación de energía eléctrica del sector privado, situación que favorece la prestación del servicio de energía eléctrica sin  racionamientos y con disponibilidad de energía eléctrica para la exportación.
Unas reflexiones sobre la necesidad de reformar la ley del indulto en España
Authors: Rodríguez-Blanco Victoria
Published: January 2023

El presente trabajo aborda una reflexión jurídica y también politológica acerca del debate social y político generado en España como consecuencia del proceso independentista iniciado por las autoridades catalanas en el 2017, con la aprobación de unas leyes para la desconexión del Estado Español y la celebración de un referéndum inconstitucional en Cataluña. Los responsables políticos fueron condenados y posteriormente indultados por el Gobierno. Se parte de considerar que el instrumento del indulto supone la mayor injerencia del poder político sobre el poder judicial y se propone afrontar una reforma de la Ley reguladora de esta institución de gracia que data de 1870  pero que nunca antes, había generado el debate jurídico sobre la urgencia de una reforma que enfatice mayores requisitos para su concesión por cuanto el abuso de la institución daña un pilar básico de la democracia cual es la independencia judicial básica en un Estado de Derecho.

En este sentido se propuso dar continuidad a este evento gracias al apoyo irrestricto del Departamento de Química y la Facultad de Ciencias de la Universidad de los Andes, de esta manera se organizaron el II y III Workshop on Adsorption, Catalysis and Porous Material (II y III WACPM) cuyo objetivo fundamental continuó siendo reunir a profesores e investigadores de prestigio internacional para compartir sus experiencias y conocimientos con los participantes del evento, además crear espacios de colaboración y continuidad con las existentes.En esta ocasión, se realizará el IV WACPM, en colaboración con la Universidad de América, Universidad de la Guajira, Universidad Libre de Barranquilla, Universidad Nacional de Colombia, y Universidad del Rosario para promover el espacio de investigación formativa y un encuentro entre científicos, colegas, amigos y estudiantes.
Estado social de derecho y criterio de sostenibilidad fiscal
Authors: Alarcón Peña Andrea , López Oliva José
Published: January 2023

Con una metodología deductiva que parte del análisis de la doctrina constitucional económica, la pretensión de este artículo es presentar las consecuencias que la introducción del criterio de sostenibilidad fiscal generó para el subsistema constitucional económico. Describe las principales características del incidente de impacto fiscal como instrumento de coordinación y dialogo de los órganos del poder público orientado a garantizar la sostenibilidad fiscal, cuando se advierta seriamente amenazada por una decisión judicial proferida por los tribunales de cierre de jurisdicción. El escrito presenta los principales retos que la reforma constitucional del Acto legislativo 3 de 2011 plantea para el Estado Social de Derecho y la imposibilidad de reconocer una transformación hacia un Estado fiscal en el que la realización de derechos este condicionada por la existencia de recursos económicos. Con esta pretensión el artículo presenta una descripción del sistema de Economía Social de Mercado, la naturaleza jurídica de la sostenibilidad fiscal y el incidente de impacto fiscal como instrumento que, en apariencia, condiciona la autonomía e independencia del poder jurisdiccional.
Evolución funcional del Delivery en los actuales modelos de negocio en Barranquilla
Authors: Pérez Gómez Leandro Miguel , Menahem Pulido Jimmy
Published: January 2023

El presente artículo, responde al análisis de la evolución funcional del Delivery y las determinaciones que se han dado para sostener la estrategia de los actuales modelos de negocio en la Ciudad de Barranquilla, desde una metodología con naturaleza mixta, anteponiendo lo cualitativo, de lo cuantitativo; dando uso a la triangulación de datos para responder al corte documental propuesto, haciéndolo veras tomando recursos de fuentes secundarias tanto científicas como de opinión pública-informativa. De este modo, hace énfasis en la sociohistoria del fenómeno de los domicilios desde la base del Marketing Informal, hasta las decisiones que en el marco de la innovación se debieron efectuar para realmente hacer de este nuevo sistema comercial, una efectiva proyección rentable y sostenible. Lo interesante, es que se puede dar cuenta de que el novedoso arquetipo se inserta en diferentes ambientes y/o espacios del mercado, es decir, se articula con el campo público y privado, cual acción implica que el proyecto se expanda a periferias y urbes en los diferentes países, se expone del mismo modo como un generador de empleo, pero se encuentra una falencia en el sistema, al precarizar los derechos de quienes dinamizan en la práctica el Delivery.
