Relación entre el nivel de liderazgo del profesor y la retención estudiantil de una institución de educación superior
Authors: Vázquez Padilla Frances Marie 
Published: November 2022

Este estudio de diseño descriptivo correlacional, longitudinal y por cohortes investigó la relación entre el nivel de liderazgo del profesor y la retención estudiantil. El estudio fue basado en los planteamientos teóricos del modelo de liderazgo completo de Bass y Avolio (1994) y el modelo de partida institucional (Tinto, 1993). Se administró un cuestionario para la determinación del nivel de liderazgo del profesor y se utilizó el sistema de información estudiantil de la institución para determinar la retención estudiantil. El cuestionario Nivel de liderazgo del profesor, fue validado y sometido a análisis de confiabilidad arrojando 0.92 en la prueba Alpha de Cronbach.
El nivel predominante entre los docentes fue el nivel En desarrollo. En términos de la tasa de retención de los facultativos, la muestra obtuvo una tasa de retención general de 88.5%. El análisis del coeficiente de correlación Spearman’s arrojó un 0.039 rs con un valor p >0.05 determinando que no existe relación entre el nivel de liderazgo del profesor y la retención estudiantil. Los hallazgos de este estudio validan la retención como fenómeno multifactorial donde el nivel de liderazgo de facultad y la retención estudiantil no se asocian como factores que inciden en la retención estudiantil.
Instructor-Generated Interactions and Course Outcomes in Online History Courses
Authors: Kelton Kristen 
Published: November 2022

Abstract
This article highlights a 2021 quantitative, correlational study examining the relationship between the weekly number of instructor-generated posts and two course outcomes within fully online, asynchronous history classes managed by one large, urban Texas community college serving a 35% Hispanic/ Latino student population. Framed by Communities of Inquiry (CoI), the study utilized archival data spanning four academic terms to answer two research questions: 1) to what degree, if any, is there a relationship between the weekly number of instructor-generated discussion posts and pass percentage rates in online history classes? and 2) to what degree, if any, is there a relationship between the weekly number of instructor-generated discussion posts and withdrawal percentage rates in online history classes? The sample contained 106 sections of History 1301 delivered via Blackboard LMS. Two data sources were collected; one showed total number of posts in the given sections, allowing calculation of a weekly mean value. The other showed course pass and withdrawal percentage rates for the sections. A positive, weak correlation was found between number of posts and pass percentage rates (r (104) = .32, p < .001). A negative, weak correlation was found between number of posts and withdrawal percentage rates (r (104) = -.47, p = .001). This article discusses the findings and provides supplemental insights for Hispanic Serving Institutions (HSIs).

Comparison of academic performance with a traditional textbook versus a digital openly-licensed textbook
Authors: Clobes Thomas , Jenkins J. Jacob , Haid Hannah , Allen Rebecca 
Published: November 2022

With the utilization of open educational resources (OER) and digital materials becoming more popular, research is needed to determine if academic outcomes are affected with the increasing shift to digital content. The goal of this research was to analyze the academic performance of students using a traditional physical textbook, as compared to those using an electronic copy of a similar textbook provided free through the campus library. The traditional and digital no-cost textbook comparisons were made between two sections of the same upper division undergraduate course taught at Hispanic-Serving Institution. The two sections of the course were taught during the Fall 2019 semester, both online, with the same faculty member facilitating both sections. There was no statistical difference in mean discussion grades, t(62)=-0.714, p=0.478, d=0.178444, mean written assignment grades, t(62)=-1.985, p=0.053, d=0.49613, and mean quiz grades, t(62)=-1.711, p=0.092, d=0.427858. However, when looking at the overall total course grade, the mean no-cost course was statistically higher than the traditional textbook course, t(62)=-2.097, p=0.042, d=0.524348. Instructors do not need to be concerned about student outcomes with the increasing implementation of such materials. Universities providing free digital access to textbooks can help address financial concerns for these students without sacrificing academic performance.

Para las instituciones postsecundarias, conocer e identificar los factores que actualmente contribuyen a fomentar que sus estudiantes en li?nea culminen satisfactoriamente sus cursos, es una prioridad para evitar el efecto contrario y adverso de la desercio?n.
Una investigacio?n realizada en el 2010, a 263 estudiantes en li?nea, revelo? resultados que permitieron ampliar el espectro de las estrategias recomendadas para trabajar con este tipo de retencio?n. La base teo?rica utilizada fue el modelo de retencio?n de Bean y Metzner (1985), el cual fue actualizado a rai?z del estudio.
El ana?lisis de datos reafirmo? que estudiar cursos a distancia ofrece al estudiante la ventaja de hacerlo con flexibilidad en te?rminos de tiempo, disponibilidad y accesibilidad y redunda en la oportunidad que tiene el estudiante de compartir ma?s con su familia y atender sus responsabilidades laborales. Tambie?n se encontro? que el escaso apoyo y participacio?n activa de los profesores, junto al insuficiente o inexistente apoyo tecnolo?gico ofrecido al estudiante, es nocivo para la retencio?n y perjudicial para la institucio?n.
La solucio?n a este moderno reto educativo es un asunto que las instituciones que abrazaron esta modalidad de ensen?anza deben priorizar creando controles de calidad para ganar prestigio acade?mico y gozar de buena salud fiscal.

De gewezen verdachte moet na een vrijspraak of sepot vaak nogmaals de strijd aangaan. Dit keer om onder andere zijn advocaatkosten vergoed te krijgen. De strafrechter toetst in deze ‘kostenvergoedingsprocedures’ of gronden van billijkheid aanwezig zijn om een schadevergoeding toe te kennen. In dit artikel gaan wij in op welke rol de keuze voor een bepaalde advocaat, diens in rekening gebrachte uren, de keuze voor een bepaalde processtrategie en overige factoren daarbij een rol (kunnen) spelen, waarbij de focus met name ligt op fraudezaken.Verder gaan wij in op de tendens dat steeds vaker een discussie plaatsvindt over de vraag of een vergoeding voor de gekozen advocaat, diens werkwijze en/of processtrategie billijk is, terwijl volgens ons de rechter zich enigszins dient te distantiëren van het geven van een te intensief c.q. inhoudelijk oordeel over deze punten.Afgesloten wordt met een aantal handvatten die van belang (kunnen) zijn bij het indienen van een schadevergoedingsverzoek van de advocaatkosten. Volgens ons dient de advocaat ervoor te waken dat de rechter binnen de grenzen van de billijkheidtoets blijft.

Authors: Jamatia Biplab 
Published: November 2022

Yoga and meditation have become widely accepted as nonpharmacologic modalities for stress and anxiety reduction as well as general health. Indira Gandhi National Open University (IGNOU) School of Health Sciences (SOHS) launched a six months-long Certificate Programme in Yoga (CPY) in July 2019 for students who have cleared their 12th class. The objective of this study was to find out the effects of online yoga training on self-perceived stress among the students of the CPY programme enrolled during the academic year 2021. This was a study with both pre- and post-tests and was carried out on the students of the CPY programme between March and December 2021. A total of 69 and 81 students participated from the January 2021 and July 2021 batches, respectively. The Perceived Stress Scale (PSS) was used as a tool to measure the level of stress. A structured close-ended questionnaire was sent by Google Forms to ascertain self-perceived stress. The total mean value of the PSS score after online yoga training decreased from 18 + 5.9 SD in the pretest to 13.7 + 6.5 SD in the post-test of students from the January 2021 batch, and from 17.4 + 5.8 SD in the pre-test to 13.1 + 5.6 SD in the post-test of students from the July 2021 batch. The difference of mean value of pre-test and post-test of both the batches of students after online yoga training were significant (p value < 0.0001). The online yoga training was effective in reduction of perceived stress score among the students of the Certificate Programme in Yoga (CPY).

Borehole Stability Assessment Using Elastoplastic Thermo-elastoplastic Finite Element Modeling Approaches
Authors: Hamid Osman , Oluyemi Gbenga 
Published: November 2022

Abstract
Wellbore stability modeling has been known in the oil and gas industry and academia for a long time. The instability-related issues significantly impact field developments, especially in complex deep reservoirs. This instability can substantially jeopardize the drilling objectives, leading to poor wellbore conditions. Most available software uses simple linear elastic modeling approaches to predict wellbore failure and determine the safe mud weight for the planned boreholes. This assumption might lead to inaccurate results.
The main objective of this research is to use an elastoplastic modeling approach to predict a yielded zone around the wellbore using Finite Element Modeling (FEM). These elastoplastic models were used in conjunction with the Drucker-Prager yield criteria.
The yielded zone is interpreted utilizing volumetric strain analysis. The result of this study will be used for any potential breakout development while drilling that might lead to increase wellbore stability-related problems. The damage or yielded zone results will be used for completion packer positioning to avoid pressure communications while packers expand.
These novel techniques will be applied to compute wellbore stability for tight sandstone formation. The methodology can be applied to other locations using the FEM approach.

Introduction
Drilling geomechanics has been well established in the oil and gas industry and academia due to wellbore stability-related issues, costing around $ billion annually (Kang et al., 2009). Many researchers have studied the impact of geomechanics on drilling operations, mainly including saving mud weight window prediction and wellbore failure to perform drilling operations safely to the TD. Plumb et al. (2004) have introduced new geomechanics processes to reduce operational risks. Their study focuses mainly on the role of geomechanics in drilling operations. Satya et al. (2011) discussed the role of geomechanics in appraising a deep tight gas reservoir. This study provided a solution for drilling a well without damaging the reservoir using underbalanced drilling technology. Hamid et al. (2014) studied wellbore stability using elastoplastic models to predict induced stresses and yield zone around the wellbore. Hamid and Rahim (2015) studied the impact of rock mechanical properties on drilling operations. Hamid et al. (2016) investigated the impact of the predrilling wellbore stability modeling in improving drilling efficiencies. All these studies provided solutions for only drilling operations without considering the role of wellbore quality on completion and stimulations.
Roles of Geomechanical Modeling During Hydrocarbon Exploration
Authors: Hamid Osman , Oluyemi Gbenga 
Published: November 2022

Abstract
Reservoir development from exploration to abandonment benefits from integrated geomechanical modeling to set guidelines and long-term operational strategies. Due to increasing operational challenges, geomechanics has become an essential part of the oil and gas industry’s daily route practice. These challenges arise when dealing with deep and tight, unconventional subsalt reservoirs, especially when drilling deviated or horizontal boreholes in a depleted formation in the minimum stress direction when intended to place multistage hydraulic fractures. This study provides innovative geomechanical solutions to address exploration challenges.
This integrated approach will incorporate all available data to construct 3D geomechanical static models to assess and characterize the reservoir properties. These properties include reservoir quality index, sweet spot, reservoir compartmentalization, pore pressure prediction, in-situ stress regime, and presence of faults and fractures. The study will also investigate the relationship between in-situ stress, fractures, faults distributions, and fluid flow and correlate fracture properties variations to the lithology changes.
The results from this study will be used as guidelines strategies for hydrocarbon exploration. The research will address the impact of the in-situ stress variations on petroleum systems, fault seal integrity evaluation, reservoir mapping, and heterogeneity. The study also provides an understanding of vertical and lateral variations of the in-situ stresses and their impact on well placement and well spacing. The types of geomechanical modeling implemented here can be used to accurately drill a safe and cost-effective wellbore that meets completion and stimulation requirements and maximize hydrocarbon production.
Implementing this innovative geomechanical workflow addresses exploration challenges and plays an essential role during reservoir development to characterize the reservoirs and optimize operations. The studies showed that implementing this workflow improves reservoir developments by saving millions of dollars and minimizing the non-productive time during the planning and exploration phase.
Acoustoelastic Simulation of Wave Propagation in Different Prestressed Media
Authors: Yang H. D. , Fu L. Y. 
Published: November 2022

Abstract
Insight into wave propagation in prestressed media is of importance to geophysical applications such as monitoring changes in geopressure and tectonic stress. This issue can be approached by the theory of acoustoelasticity that accounts for nonlinear strain responses due to stresses of finite magnitude. In this study, a rotated staggered-grid finite-difference (RSG-FD) method with an unsplit convolutional perfectly matched layer (CPML) absorbing boundary is used to solve the relevant acoustoelastic equations with third-order elastic constants for elastic wave propagation in prestressed media. Numerical acoustoelasticity simulations for wave propagation in single- and double-layer models are performed under four states of prestresses, confining, uniaxial, pure-shear, and simple-shear. The results display the effective anisotropy of elastic wave propagation in acoustoelastic media, illustrating that the prestress-induced velocity anisotropy is of orthotropic features that are strongly related to the orientation of prestresses. These examples demonstrate the significant impact of prestress conditions on seismic responses in both phase and amplitude.

Introduction
The impact of prestressed zones on seismic waves is an important issue that affects the interpretation of the results by seismic imaging and inversion. It is well known that acoustic velocities in rocks are sensitive to prestresses. The theory of acoustoelasticity, as an extension of the classical theory of elasticity, is set up under the framework of hyperelasticity (Shams et al., 2011). The theory relates elastic moduli to prestresses (or residual stresses) in solids (Pao and Gamer, 1985), resulting in an effective anisotropy for wave propagation in acoustoelastic media. It has been used to account for stress-induced velocity variations in rocks (Johnson and Shankland, 1989), therefore perhaps providing the potential to understand the acoustic response to in-situ stresses (Sinha and Kostek, 1996; Huang et al., 2001) and, in turn, to monitor changes in geopressure and tectonic stress. Theoretical and experimental investigations of acoustoelasticity for wave propagation in prestressed rocks have made great signs of progress, but with limited literature on numerical simulations for acoustoelastic wave propagation. As a useful complement to the theoretical solutions of acoustoelastic equations, numerical acoustoelasticity simulations are thought to provide further insights into the stress-induced variations in velocity and anisotropy.
