Authors: Monsante Moy Isabella , Novoa Suárez Ariana , Quintanilla Gutiérrez Alejandra 
Published: March 2022

El crecimiento exponencial del e-commerce en el Perú ha generado nuevos problemas en el cumplimiento de los derechos de los consumidores y la consecuente desconfianza del consumidor en las transacciones de comercio electrónico. Diversas autoridades han propuesto como solución que se regulen las transacciones de e-commerce realizadas en el ámbito nacional, en línea con la tendencia de la Unión Europea a regular los mercados digitales. Sin embargo, ¿es la iniciativa legisladora una solución idónea para resolver los nuevos problemas generados por el e-commerce?.En el presente artículo, las autoras analizan cómo una ley de e-commerce no resolvería por completo los nuevos problemas generados por este y plantean la necesidad de contar con soluciones desde el mercado, elaboradas a partir de nuevos mecanismos tecnológicos como los smart contracts. Estas herramientas, junto con el incentivo de las autoridades que protegen derechos de los consumidores, podrán resolver de forma eficiente los nuevos problemas que se generan en esta nueva década.
Gobierno corporativo en tiempos de Venture capital
Authors: Porto Urrutia José Miguel 
Published: March 2022

Es indiscutible la importancia de contar con políticas de buen gobierno corporativo que respondan a las particularidades de la sociedad; sobre todo, en estructuras de capital (como las startups), cuya dinámica especial en la industria (del venture capital) genera un alto riesgo de vulnerar los intereses de grupos en desventaja (como lo son los accionistas minoritarios). Así como también, existe el riesgo de influenciar indebidamente la gestión en razón de la posición privilegiada que determinados grupos detentan (como lo son los inversionistas con alta capacidad financiera).En ese orden de ideas, el presente artículo expone los retos y complejidades que atraviesa la industria del venture capital, fundamentalmente en el mercado de startups peruano. Asimismo, el autor analiza algunas propuestas de buen gobierno corporativo, a efectos de trazar un punto de partida en la búsqueda de prácticas y políticas que permitan la consolidación de la figura en el país.

Authors: Calderón Paredes Cecilia 
Published: March 2022

En el contexto del Proyecto de Ley 4243/2018-CR, Ley del Empleo Digno que regula a los trabajadores de Plataformas Digitales, es innegable la existencia de una nueva realidad empresarial dominada por el fenómeno de las plataformas digitales. Esta nueva dinámica reta los parámetros clásicos del derecho laboral y coloca en debate la existencia o no de un vínculo de naturaleza laboral entre los agentes partícipes de ella.En el presente artículo, y bajo una visión mercantillaboral, la autora destaca la existencia de una novedosa economía de plataformas, identifica a los actores intervinientes en ella y la dinámica que esta incorpora en el mercado. De igual manera, examina los nuevos indicios de laboralidad que podrían surgir en este escenario, conforme han sido reconocidos por el Tribunal Supremo español en un último pronunciamiento referido al tema: el caso Glovo.
Hacia una adecuada protección del Derecho Fundamental al Secreto e Inviolabilidad de las Comunicaciones en la Relación Laboral: análisis constitucional a la luz de las nuevas tecnologías
Authors: Feijóo Cambiaso Raúl Humberto 
Published: March 2022

Actualmente nos encontramos inmersos en un acelerado progreso tecnológico, el cual trae consigo ventajas para el mundo de las comunicaciones, pero retos para los derechos fundamentales. Estos desafíos se evidencian en el ejemplo de las comunicaciones dentro del contexto laboral. Es tal el fenómeno que tanto la Corte Suprema como el Tribunal Constitucional peruano han puesto de manifiesto la protección del trabajador ante una eventual inspección por parte del empleador del contenido de su correo electrónico institucional, salvo que exista una investigación de carácter judicial previa.El presente artículo analiza el derecho al secreto e inviolabilidad de las comunicaciones en las relaciones laborales desde una perspectiva actual. El eje de la investigación versa sobre el tratamiento del soporte tecnológico brindado por los empleadores, en especial la regulación sobre los correos electrónicos institucionales. Para ello, el autor realiza un análisis comparado de la jurisprudencia peruana, española y del Tribunal Europeo de Derechos Humanos, y concluye explorando la problemática del control de las conversaciones en las redes sociales del trabajador realizadas mediante un soporte electrónico brindado por el empleador.
Articulating Translanguaging as Pedagogy of Empowerment for Racialized, LanguageMinoritized Bilinguals: From Concepto to Proyecto through Digital Storytelling
Authors: Prada Josh 
Published: March 2022

This article provides an overview of a digital storytelling proyecto final (final project) completed by 18 young bilingual Latinxs as part of a Spanish for “heritage/native” speakers course at a university in the U.S. Midwest. Specifically, the article charts out the move from concepto (concept) to proyecto, zooming in on key aspects of digital storytelling through a translanguaging lens, with an emphasis on how this pedagogy may serve the purpose of empowerment among language-minoritized, racialized multilinguals. This pedagogy opens the language curriculum to ways of meaning- and sense-making that support principal objectives and goals in heritage language education while promoting the handing over of decision-making to students in transformative and liberating ways. This perspective, while developed in the context of Spanish as a minoritized language in the United States, is applicable to other contexts where language teaching and learning meet sociopolitical pressures of minoritization, oppression, and the erasure of personal and collective histories.
Cet article fournit un survol d’un récit numérique proyecto final (projet final) effectué par 18 jeunes latinxs bilingues dans le cadre d’un cours pour hispanophones « de souche » dans une université du Midwest américain. Plus précisément, l’article définit le passage du concepto (concept) au proyecto, en se concentrant sur les aspects clés du récit numérique par le biais d’une optique de translanguaging, avec une emphase sur la façon dont cette pédagogie peut servir à favoriser la valorisation chez les personnes multilingues racialisées en situation de minorité linguistique. Cette pédagogie ouvre le programme de langue à des façons de donner un sens et une signification soutenant les buts et objectifs principaux de l’enseignement de la langue patrimoniale tout en promouvant la passation de la prise de décision aux étudiants de manière transformative et libérante. Cette perspective, quoiqu’élaborée dans le contexte de l’espagnol comme langue minoritaire aux États-Unis, peut s’appliquer à d’autres contextes où l’enseignement et l’apprentissage de la langue rencontrent des pressions sociales de minorisation, d’oppression et d’effacement des histoires personnelles et collectives.

Human life is full of uncertainty that has enormous risks. Insurance is a one of methods that can help humans reduce those risks. Human needs for insurance causes competition among insurance companies in Indonesia to become very competitive. One factor that makes insurance companies to compete is to have its customers who make insurance renewals. Thesis discusses analysis of factors that influence insurance renewal using Analytical Hierarchy Process (AHP) method and the ranking of customer’s favorite insurance for renewal using the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) method. Five criteria have been determined with each criterion having subcriteria in this study. AHP method is used to calculate the weight of criteria and to determine the factors that influence customers the most to do renewal. The FTOPSIS method is used to determine the best alternative. The results of the analysis using these methods conclude was the main factor that influences the customers in conducting renewals is feature with the subcriteria of health protection needs. Meanwhile, the ranking of customer’s favorite insurance in conducting renewal is Takafulink Salam Cendikia with proximity coefficient value of 0,645, Takaful Al-Khairat with value 0,563, Takaful Dana Pendidikan with value 0,552, and Takafulink Salam with value 0,341

In this paper, a Frobenius functional is constructed in order for the Lie algebra to be the real Frobenius Lie algebra of dimension 8. Moreover, a bilinear form corresponding to this Frobenius functional is symplectic. Then the obtained symplectic bilinear form induces the left-symmetric algebra structures on . In other words, the Lie algebra is the left-symmetric algebra. In particular, we give the formulas of its left-symmetric algebra structure explicitely. The left-symmetric algebra structures for case of higher dimension of this Lie algebra type are still an open problem to be investigated.

Comparing the Risk of Osteonecrosis of the Femoral Head Following Intra-Articular Corticosteroid and Hyaluronic Acid Injections
Authors: Varady Nathan H. , Abraham Paul F. , Kucharik Michael P. , Freccero David M. , Smith Eric L. , Martin Scott D. 
Published: March 2022

Background:
Although intra-articular corticosteroid injections (CSIs) are a cornerstone in the nonoperative management of hip pathology, recent reports have raised concerns that they may cause osteonecrosis of the femoral head (ONFH). However, these studies might have been limited by nonrepresentative patient samples. Therefore, the purpose of this study was to assess the incidence of ONFH after CSI and compare it with the incidence in a similar patient population that received a non-CSI injection.

Methods:
This was a retrospective propensity-matched cohort study of patients in the MarketScan database who underwent an intra-articular hip injection from 2007 to 2017. Patients receiving hip CSIs were matched 4:1 with patients receiving hip hyaluronic acid injections (HAIs) based on age, sex, geographic region, comorbidities, type of hip pathology, injection year, and baseline and follow-up time using propensity scores. The patients’ first injections were identified, and the time to development of ONFH was analyzed using Kaplan-Meier curves and Cox proportional-hazards models. Patients with a history of osteonecrosis or those who received both types of injections were excluded.

Results:
A total of 3,710 patients undergoing intra-articular hip injection were included (2,968 CSIs and 742 HAIs; mean [standard deviation] age, 53.1 [9.2] years; 55.4% men). All baseline factors were successfully matched between the groups (all p > 0.57). The estimated cumulative incidence (95% confidence interval [CI]) of ONFH for CSI and HAI patients was 2.4% (1.8% to 3.1%) versus 2.1% (1.1% to 3.5%) at 1 year and 2.9% (2.2% to 3.7%) versus 3.0% (1.7% to 4.8%) at 2 years (hazard ratio, 1.05; 95% CI, 0.59 to 1.84; p = 0.88). The results held across a range of sensitivity analyses.

Conclusions:
The incidence of ONFH after intra-articular hip injection was similar between patients who received CSIs and those who received HAIs. Although this study could not determine whether intra-articular injections themselves (regardless of the drug that was used) lead to ONFH, the results suggest that ONFH after CSI often may be due, in part, to the natural course of the underlying disease. Future randomized controlled trials are needed to definitively answer this question; in the interim, clinicians may be reassured that they may continue judicious use of CSIs as clinically indicated.

Quantitative Production Steering through High-Definition Boundary Detection Service for the Sustainable Development of the Bottomwater Reservoir

Published: March 2022

Abstract
In the northern part of the South China Sea, P oilfield entered the mature stage with a high water cut. As an important contribution to the sustainable development of this field, a horizonal infill campaign targeted the unexploited areas for their valuable remaining oil for improving oil recovery. However, the sparse well control and low-resolution seismic data induced high uncertainties regarding the structural profile, reservoir properties, effective oil column, and remaining reserves with the bottomwater drive in the infill well area. These uncertainties greatly affected the production steering efficiency in the complex reservoirs and well performance, which cannot be effectively addressed by the conventional logging and modeling technologies.
Predrilling modeling results and global successful cases could increase operators the confidence in using the high-definition boundary detection service (HDBDS) for achieving well objectives. Without any artificial assumptions, HDBDS could provide the stochastic resistivity inversion to remotely identify the quantitative subsurface features, including layer numbers, resistivity and anisotropy distribution, thickness, and dip. In the specific operation area, the inversion can detect the reservoir features up to 3 m from the borehole, which could quantitatively reconstruct the subsurface profile to efficiently guide the horizontal geosteering operation for maximum standoff from the water zone. Furthermore, the production steering can be enhanced through optimizing the corresponding water-controlled completion configurations.
During the real-time execution of the horizontal infill wells with an approximate 500- to 600-m section, HDBDS inversion could map the effective boundaries with a distance of up to approximately 3 m, including reservoir top and bottom, water zone top, as well as some interbed boundaries. Combining conventional measurements and HDBDS inversion, the subsurface model was quantitatively reconstructed with the obvious deviations from the original elements. Subsequently, the horizontal wells were precisely controlled for enough oil column, even with a shorter production interval than prognosis in some wells. In the updated reservoir model, the inflow control device (ICD) water-controlled completion configuration was specifically optimized to delay bottomwater breakthrough. As a result, the effective production steering was achieved, with the actual well performance better than expected. Furthermore, the oil trap column and remaining oil reserves could be reassessed to evaluate the production potential and further development direction in this field.
Generally, HDBDS inversion could update the quantitative model to induce the production steering, which was valuable to contribute to the sustainability of this bottomwater field in the deep-development stage.

Published: March 2022

AbstractWith the ongoing paradigm shift in the Oil and Gas industry towards greener alternatives with net-zero objectives, several developing technologies have been recently deployed or proposed as promising solutions. The overall goals are to decrease carbon footprint and improve the projects’ economics and net present value (NPV). This study outlines the latest developments with underlying principles, practices, and economics. This holistic approach encompasses the overall feasibility with the challenges and the benefits.A comprehensive literature survey has been carried out on publicly available data to provide the theoretical background, rationale of use, screening and selection criteria, difficulties, and the workarounds. Systems to integrate the green methods with the respective oil and gas processes appear in detail, from screening to implementation. We outline economics under various scenarios with CAPEX methods and OPEX-intensive approaches to maximize the NPV. The technical details of the integration under multiple conditions that affect the system's efficiency, such as weather, seasonal temperature changes, wind, and solar exposure, have been investigated.Efficient integration of the selected green methods with the associated oil and gas process proves to be a concrete step towards a net-zero objective. Such integration brings additional benefits of improved economics with minimal effects in terms of capital intensiveness or other burdens on the overall economics. These items range from solar thermal applications in heavy oil recovery to heat recovery from the produced fluids, biomass, geothermal, wind, and wave for offshore processes. Cases with multigreen energy methods, such as solar and heat recovery, demonstrate promising outcomes.This article examines some of the latest green methods with various aspects corresponding to the selected oil and gas processes. We specifically focus on energy generation through standalone green methods and extracting energy from oil and gas processes in a greenway. The overall objective is to close the current gap in the literature.

Abstract
Advancements in digital technology and digitalization of industrial process have opened new frontiers for the oil and gas industry. The amount of historical data generated from drilled wells over the past decades of operations is currently being digitized and processed to provide operators with the option to make more informed decisions based on previous experiences that current staff may not be aware of due to the constant loss of experience during industry downturns. The industry is combating this loss of experience through the innovative use of digitalization, integrated operations, and automation. Real time support centers operating under integrated operations business model are now utilizing digital twins (high fidelity models of the ongoing process being supported) to run forecasting simulations and compare results to digitalized historical data with the help of artificial intelligence and expert systems to aid with decision making and training junior staff. The existence of high-fidelity models, and digital twins is a solid foundation for automation. In this paper a review of the emergence of these technologies is used to identify where digital twins can be used as the foundation of automation solutions that would shift the focus of drilling crews from efficiency to operation and process safety.
