Assessments under the United Nations Sustainable Development Goals: A Bibliometric Analysis
Authors: Londoño-Pineda Abraham Allec , Cano Jose Alejandro
Published: March 2022

The United Nations announced its 2030 Agenda for Sustainable Development worldwide in 2015. Comprehensive assessments of member states’ performance towards achieving the related UN Sustainable Development Goals (SDGs) have since become a major challenge for national and subnational governments. This article presents a bibliometric analysis on the assessment of SDGs, at both the general and specific levels, based on 418 publications obtained from Scopus. The general level of analysis includes the number, types, and subject areas of documents published each year, as well as considerations such as the most-cited publications and the leading authors, journals, countries, institutional affiliations, and funders. The specific level of analysis includes a study of the relevant concepts in the publications and their relationships, allowing for the identification of predominant assessments under the 2030 Agenda, and of the most-often evaluated SDGs. Results indicated a focus on measuring impacts and risks, with SDGs 3, 6, 13, 7, 8, and 4 having been assessed the most often among the 17 SDGs, which is consistent with findings in prevalent subject areas such as environmental sciences, social sciences, medicine, and energy. Future works should address assessments under the 2030 Agenda more comprehensively, including analyses on trade-offs among the SDGs and on the transversal nature of some of these goals.

La oferta de pódcast nativo en Puerto Rico: la identidad cultural del sector independiente frente a la industria periodística
Authors: Ortiz Díaz Gabriela , Moreno-Moreno Elsa , Vargas Enrique
Published: March 2022

El podcasting se debate entre posibilitar las culturas participativas gracias a la expresión personal y cultural de podcasters independientes o ser una industria promovida desde los medios periodísticos y la “plataformización” del mercado de la comunicación. El caso del contexto sociocultural de Puerto Rico también enfrenta esta cuestión y es de interés identificar la oferta estable y regular de pódcast nativos realizada por los sectores del podcasting independiente y la industria periodística. Basada en las teorías de la cultura participativa y la economía política de las industrias culturales, esta investigación aporta el primer análisis exploratorio en profundidad de la oferta de pódcast relacionados con Puerto Rico a partir de un corpus o muestra de 815 pódcast según los datos del Observatorio de Podcast de Puerto Rico. Se aplica la metodología de análisis de contenido cuantitativo para caracterizar dichos pódcast de acuerdo a 11 variables: título/nombre, creador/usuario o grupo mediático/operador, producción propia u original para la red o no, temática, género o formato narrativo, año de inicio de la producción, número de episodios, duración media de los episodios, frecuencia de publicación, autoría/presentación y plataforma alojadora o de publicación del pódcast. Los resultados evidencian que los podcasters independientes contribuyen a que el usuario disponga de 743 pódcast nativos (723 son amateurs y 20 de medios periodísticos). Los pódcast independientes conforman un espacio de autoexpresión cultural frente a la cultura mainstream. No obstante, marcas periodísticas vinculadas a la prensa como El Nuevo Día, El Vocero y Metro Puerto Rico fomentan el pódcast nativo de noticias. Anchor concentra el alojamiento y favorece la intermediación
Comunicación política, institucional y medios de comunicación en tiempo de pandemia. Análisis del diálogo sobre vacunas en cinco países iberoamericanos
Authors: Peña-Fernández Simón , Larrondo-Ureta Ainara , Morales-i-Gras Jordi
Published: March 2022

El actual contexto mediático se caracteriza como un sistema híbrido en el que los viejos y los nuevos actores coexisten y, a la par compiten, por su hegemonía en la esfera mediática. En este contexto, el Covid-19 ha generado una “infodemia” o sobreexposición informativa que ha dificultado el acceso de la ciudadanía a fuentes y orientación fiables. Por ello, el objetivo principal de este artículo es caracterizar a los actores políticos, institucionales y mediáticos que han informado en Twitter sobre las vacunas y los procesos de inmunización durante la pandemia del Covid-19 en cinco países iberoamericanos: Argentina, Brasil, Chile, España y México. Para ello se han analizado un total de 68.822 tuits procedentes de 84 cuentas pertenecientes a los presidentes del país, las cuentas oficiales de los gobiernos, las autoridades sanitarias y sus portavoces, y los principales medios de comunicación. Los resultados indican que la actividad más intensa y el peso informativo lo han llevado las autoridades sanitarias y los medios, aunque las cuentas personales de los portavoces y representantes políticos han logrado un engagement mucho mayor. A pesar de que la interacción de las audiencias ha sido mayoritariamente positiva, los usuarios más activos han cuestionado de forma generalizada los mensajes publicados, en especial los de los representantes políticos. Estos resultados permiten concluir que en el sistema comunicativo híbrido medios y gabinetes institucionales muestran una capacidad similar de difundir mensajes a través de las redes sociales que generan una recepción favorable, aunque en el caso de los representantes públicos el engagement, y también la polarización, son mucho mayores.
Privatización, servicio público y digitalización. El caso de 7 TV
Authors: Rodríguez Gómez Eduardo Fco. , Rosique Cedillo Gloria Josefina
Published: March 2022

Esta investigación contribuye al estudio sobre los procesos de privatización que experimentan los medios audiovisuales públicos en el actual contexto de convergencia digital. Mediante un estudio de caso de la televisión pública regional 7 TV de Murcia, que se realizó mediante una revisión documental complementada con entrevistas a expertos, se analiza si la privatización integral en la gestión de la televisión autonómica ha impulsado su desarrollo digital, permitiendo una mejora en sus acciones de transparencia y rendición de cuentas y favoreciendo la participación ciudadana en la toma de decisiones. Los resultados evidencian que, pese al conocimiento preciso de los cambios que deben acometerse ante la inminente transformación del sector audiovisual, la 7 TV se halla en una fase incipiente de cambio, anclada a un sistema de producción y distribución continuista que produce iniciativas modestas y en el que la participación ciudadana está muy limitada.
Condiciones individuales de producción periodística en medios independientes cubanos
Authors: Somohano Fernández Abel
Published: March 2022

Este artículo tiene como objetivo analizar condiciones individuales de la producción periodística en dos de los medios independientes de la estructura mediático-partidista en Cuba de mayor relevancia y reconocimiento a nivel internacional. En la investigación se asumió como técnica la entrevista en profundidad a 40 periodistas de estos medios. Se detectó que estas condiciones están marcadas, fundamentalmente, por la confluencia en las dos organizaciones mediáticas de jóvenes egresados de las carreras de Periodismo en el país con una ubicación espacial múltiple, y referentes y trayectorias profesionales diversas. Se detectó también una identificación profesional con las funciones del periodismo de informar, fiscalizar al poder, participar en el debate social y mostrar la sociedad en su diversidad, entre otras. Además, se encontraron inquietudes personales ante la violencia operante sobre el periodismo independiente en la Isla. Se concluyó que estas condiciones individuales se materializan en términos de una discursividad (y representación) profesional antiautoritaria compartida por los periodistas. Como parte de las conclusiones del trabajo se propone una comparación con hallazgos de indagaciones situadas en otros espacios nacionales.

Published: March 2022

En las últimas décadas, los juegos digitales se han convertido en parte esencial de la cultura de los adolescentes y jóvenes. Los consumidores de contenidos de estas plataformas se han incrementado notablemente, así como los estudios en torno a ellos. El objetivo de esta investigación consiste en analizar los contenidos generados por los usuarios en los juegos móviles Episode: Choose Your Story y Choices: Stories You Play, los cuales poseen una gran cantidad de usuarios jóvenes que difunden y expanden las historias a través de las redes sociales más importantes. Se realizaron dos estudios de casos sobre la estructura de las narrativas transmedia de estos juegos y se empleó una metodología cualitativa basada en el análisis narrativo y el análisis de contenido. Los resultados indican que, si bien ambos juegos expanden las historias en diversas plataformas, la presencia de un laboratorio de escritura por parte de Episode genera un comportamiento más delimitado en los usuarios en comparación con Choices, el cual brinda una mayor posibilidad de convertir a los consumidores en prosumidores. La enorme comunidad de fans en torno a estos juegos, corrobora la importancia de las narrativas expandidas en distintos medios.

Regional Policy as a Significant Element of Ensuring the National Security of the Russian Federation
Authors:   Irkutsk State University, Zulyar Yu. A. , Zulyar R. Yu. ,   Irkutsk State University, Rybalko M. L. ,   Irkutsk State University
Published: March 2022

Regional policy is a significant element of the domestic politics of a unitary state, and for a federal state it is a zone of increased attention. Russia is an asymmetric ethno-confessional democratic federation, therefore, there is a constant competition between centrifugal and centripetal trends. To ensure the integrity of the state, the leadership of the Russian Federation (RF) has to constantly transform regional policy, based on the peculiarities of the socio-economic and political situation. In the arsenal of this policy, there is a diverse arsenal of means and methods of countering separatism and extremism, which was used throughout the post-Soviet period of Russia's history. Within the first decade, the regional policy of the country's leadership was unsuccessful and ineffective, which actually led to a civil war and the beginning of the country's collapse. Since 2001, as a result of the application of radical and unpopular measures and the reform of socio-economic relations, the situation has been reversed, and then normalized. This became possible as a result of the restriction of democratic principles and the strengthening of authoritarian elements of regional politics, as well as the preservation of the archaic asymmetric structure of the federation.

Published: March 2022

Objective: To evaluate the effectiveness and safety of Bushen Huoxue prescription in the treatment of recurrent spontaneous abortion (RSA) due to prethrombotic state (PTS). Methods: Databases such as CNKI, WanFang, VIP, CBM, PubMed, Embase, and Cochrane Library were searched for randomized controlled trials on Bushen Huoxue prescription in treating RSA due to PTS from inception to March 2021; meta-analysis was performed by RevMan Version 5.3.0 following quality evaluation. Results: Seven trials were included, with 496 patients; the meta-analysis indicated that Bushen Huoxue prescription has advantages on the improvement of total clinical effective rate [RR = 1.22, 95% CI (1.10, 1.35), Z = 3.80 (P = 0.0001)], embryo survival rate at pregnancy of 12 weeks [RR = 1.25, 95% CI (1.10, 1.41), Z = 3.53 (P = 0.0004)], D-dimer levels [SMD = -1.59, 95% CI (-2.20, -0.97), Z = 5.07 (P < 0.00001)], and fibrinogen levels [MD = -1.00, 95% CI (-1.29, -0.70), Z = 6.61 (P < 0.00001)], but the statistical heterogeneity was significant; in terms of incidence of adverse reactions, there was no statistical difference between Bushen Huoxue prescription and western medicine. Conclusion: Compared with western medicine alone, Bushen Huoxue prescription alone or in combination with western medicine showed significant advantages in improving the overall clinical efficiency, embryonic survival rate at 12 weeks of pregnancy, and reducing D-dimer values as well as fibrinogen levels, without any significant difference in the incidence of adverse effects; however, the number of included studies is small and there are drawbacks, such as small sample size and low quality; therefore, high-quality clinical studies with large sample size and rigorous trial designs are needed in the future to provide a reliable basis for the effectiveness and safety of TCM in reducing the incidence of RSA due to prethrombotic state.

Análisis de percepciones respecto al deterioro ambiental y el desarrollo sustentable: un manejo desigual de información
Authors: Reyes Guillén Flor Ivett , Fonseca C´órdoba Socorro , Muñoz Alonso Reyes Bárbara
Published: March 2022

El presente documento contiene los resultados de un estudio realizado en San Cristóbal de Las Casas, Chiapas, México, con el objetivo de analizar las percepciones de la población respecto al deterioro ambiental y al concepto de desarrollo sustentable. El estudio se basó en el análisis de percepciones como fuente de datos. Los principales hallazgos fueron: 1) la población de estudio detecta cambios ambientales, pero los considera necesarios para el desarrollo, y 2) se define el desarrollo sustentable como “cuidado ambiental” que parte de los programas de gobierno, o bien como una modalidad que permite contar con un empleo para el bienestar familiar. La construcción de conceptos juega un papel importante para medir el impacto de las acciones ecologistas, aunque la conceptualización de “desarrollo sustentable” en la población actualmente no incide en el desarrollo y la valoración de programas ambientales.

Recently, the use of Model-Driven Engineering (MDE) via metamodeling approach is gaining more attention for software applications development. The community from the healthcare domain also attempts to employ the metamodel approach for producing quality healthcare applications. Healthcare applications have become an imperative in every attempt to improve healthcare management. Numerous studies reported that the healthcare domain is seen as a complex and unique domain, which involves dynamic characteristics. In addition, it is widely recognized that the increase of information exchange in the healthcare domain is caused by the diversity of healthcare data. This has led to the increase use of information technologies in the healthcare industry so as to enhance the healthcare delivery process via healthcare applications. However, the complexity of healthcare information leads to ineffective models and design of healthcare applications. Modeling the healthcare processes and developing healthcare applications are challenging tasks. Hence, the advances of MDE have influenced the use of the metamodeling technique in the development of healthcare applications. Various metamodels are developed as a solution to provide a clear healthcare process model and a correct healthcare application. The aim of this paper is to analyse the use of the metamodel-based approach in designing healthcare applications. We believe that the metamodel-based approach would improve the development of healthcare applications.

A disc-type rotor magnetic bearing with 3-pole magnet is considered in the paper. The disc-type rotor supported by electro-magnetic forces has potential in industrial application especially in flywheel energy storage systems. However, coupling phenomenon in acting forces makes the balancing control problem in the system challenging. Based on analysing magnetic forces acting on the rotor, the coupling mechanism is identified, and a coordinate transformation is formulated to decouple acting forces. Thanks to the transformation, control design is straightforward for each control channel leading to simple and straightforward control design. The goal of the design is to keep the rotor at its desired equilibrium in the presence of disturbance and parameters variation. The goal can be achieved when the controller is designed in discrete-time domain based on the linearized model, then, the disturbance is compensated by employing the one step delay technique. The validity and robustness of the controller are verified by various numerical simulations in which original nonlinear model is used.

Multi-path fading is a severe issue that causes fluctuations in the amplitudes of the received signals. For combating this issue, several researchers have used cooperative communication in the Long-Term Evolution (LTE)-advanced system. To further decrease the degradative effects of transmitted signals, various error correction techniques can be used to recover the erroneous components, especially when the channel has been deep fading. The paper investigates the general performance of the Convolutional Codes (CC) in the LTE-advanced cooperative system and compare it with the Bose-Chaudhuri-Hocquenghem (BCH) codes. The comparison is based on WINNER II project as the channel model between the nodes in the two coding processes. To validate the advantages of BCH code, the process were tested on three different environments; a suburban macro-cell, urban macro-cell, and the rural micro-cell with prior study to understand the appropriate relay height in every environment. Path loss models for each environment were derived and proposed as part of the proposed simulation framework. Conducted simulation studies based on bit error rate and direct connection showed that the use of the CC and the BCH codes in a relay technologies could significantly increase the system performance. It was noted that the performance of the system which used BCH nodes was better than the system using CC nodes in an LTE-advanced cooperative system.

Housing has become a vital instrument in daily life, not because of the cost and function’s only but housing can provide other attributes of a feasible urban life. Thus, Malaysia's government has struggled to cater affordable housing to counter economic concerns and adopt a sustainable housing development aspect for a better quality of life. However, even the housing affordability of low and middle-income earners has been improved, but some of them are remains in debating. The objective of this paper is to measure the sustainability element in PRIMA affordable projects in Malaysia as well as to determine the satisfaction level of sustainable affordable housing practice among PR1MA residents. The data were collected from 97 survey forms distributed amongst PR1MA residents through Google form and self-administered and were considered as useful data for further analysis. The results show that only social and environmental elements were determined as sustainability elements in PR1MA affordable housing in selected PR1MA projects in Malaysia. Moreover, the results revealed that majority respondents have low satisfaction level on economic sustainability in sustainable affordable housing practice within their residential area. Thus, this result has a significant contribution to the stakeholders who are directly or indirectly participated in affordable housing development and specifically PR1MA projects. This result also helps the policy makers and practitioner for emphasizing several important elements for developing affordable housing in future.

This paper presents the modelling of significant Logistics Service Supply Chain (LSSC) factors affecting oil and gas industry performance in the UAE. Data collection involved the projects of Abu Dhabi National Oil Company (ADNOC). The model consisted of six independent constructs, one mediator’s construct and one dependent construct. The six independent constructs are Transport Management; Inventory Management; Order Process Management; Information Flow Management; Agility of logistics service and Integration capabilities of logistics. The mediator construct is logistic information, and the dependent construct is organization performance. The modelling used the AMOS-SEM approach, which indicates the graphical interaction of the factors toward the company performance. The data used to develop the model was gathered through the structured questionnaire survey amongst the selected respondents from the ADNOC oil and gas company in UAE, with a response rate of 90%, indicating strong participation from the population. Total 379 questionnaire forms were collected and used for analysis. The model was constructed according to the conceptual model and assessed at the measurement and structural level of the model. All the individual measurement models achieved the threshold criteria while the structural model reached the required fitness index. Then the model was run for hypothesis testing and found that four of the paths which are Transport Management; Inventory Management; Order Process Management; Information Flow Management have achieved a significant level. Also, Logistics Information Systems has not mediating effect to the relationship of Logistics Service Supply Chain (LSSC) factors affecting oil and gas industry performance in the UAE. This model contributed to the body of knowledge in presenting the relationship of factors affecting the performance of logistics in the oil and gas industry. It is hoped that the oil and gas practitioners can gain from this model to be applied in their profession.
