Students’ Affective Learning Outcomes and Academic Performance in the Blended Environment at University: Comparative Study
Authors: Kobicheva Aleksandra , Tokareva Elena , Baranova Tatiana
Published: September 2022

This study examines how the gender of students and their level of education (undergraduate or postgraduate students) influence affective learning outcomes in a mixed environment. The research model is based on four key indicators: satisfaction, perception of experience (perceived usefulness, ease of use, and perceived behavioral control), perception of benefits (general learning effectiveness, knowledge sharing and increasing, study skills improvement, and sense of progress), and academic performance. Moderating factors, including gender and education level, were used to define the distinctions in the measured results. The study was conducted in the fall semester of 2021. The target samples were students of undergraduate and postgraduate levels studying during the semester in the blended environment. A total of 513 students from Peter the Great Polytechnic University took part in the research. The online questionnaire was conducted to define the affective learning outcomes of students in the blended environment and the influence of affective outcome factors on academic performance. The Likert-type five-point scale was used to determine all the variables. For our statistical analysis, we used SPSS 24.0 and SmartPLS 3.0 programs. Two tests were implemented to determine the differences between gender and education level in relation to students’ affective learning outcomes. Finally, our study revealed how distinctive aspects of affective learning outcomes impact academic learning outcomes in a blended format using linear regression analysis. According to the results obtained, the results between males and females were similar and academic performance results were mostly predicted by satisfaction level. A difference was revealed between undergraduate students’ results and postgraduate students’ results. Perceived benefit has a greater effect on academic performance for postgraduate students, while satisfaction level has a greater effect on academic performance results for undergraduate students than for postgraduate students.

Authors: Yu Shuzhong , Ni Zhouyou , Yang Zhende
Published: September 2022

Karst rocky desertification (KRD) is a typical fragile ecological environment with its key and difficult management point being vegetation restoration. Therefore, it is crucial to determine the adaptation mechanisms of suitable plants for ecological restoration in KRD areas. D. odorifera is a tall leguminous, woody plant with high medicinal and wood value. This study aimed to explore the adaptation strategy of the D. odorifera root system to the shallow karst fissure-soil (SKF-S) habitats. The growth, biomass, spatial root distribution, morphological characteristics, and physiological responses of D. odorifera seedlings under different treatments were studied in pots simulating SKF-S habitats. Through the experiments conducted, the following conclusions were obtained: (I) D. odorifera enhanced its ability to acquire limited resources through an allocation adjustment strategy (adjusting the biomass allocation strategy, increasing the root shoot ratio, prioritizing organ leaves and 3-level roots), which effectively offset some of the adverse effects; (II) with an increase in the stress severity, D. odorifera improved its resource acquisition adaptive strategy by reducing the root diameter and increasing the contact area with soil; (III) the spatial development characteristics of its root system were mainly manifested in the ability to grow vertically, deeper, compared to a horizontal extension; (IV) D. odorifera did not passively endure rocky desertification stress but actively improved its metabolism through root metabolic activity and SOD enzyme activity.

Authors: Khanal Avishek , Rahman Mohammad Mafizur , Khanam Rasheda , Velayutham Eswaran
Published: September 2022

The COVID-19 pandemic has impacted all sectors of the tourism industry, particularly air transportation. However, air transport remains an important contributor to economic growth globally. Thus, this study examines whether air transport (a proxy for tourism) stimulates economic growth to validate the air-transportation-led growth hypothesis (ALGH) in the Australian context. To conduct the study, we analyse the asymmetric long-run and short-run impacts of the air passengers carried (a proxy for tourism) on the gross domestic product (GDP) in Australia. We use the nonlinear autoregressive distributed lag (NARDL) modelling approach on data for Australia from 1971 to 2019. We also examined the effects of selected control variables (i.e., energy consumption, financial development, socialisation, and urbanisation) on economic growth. In both the short and long run, we observed statistically significant asymmetric impacts of air transport on economic growth. The positive shocks in air transport propel the long-term growth of Australia’s economy. Additionally, according to the findings, negative shocks of air transport have a stronger detrimental impact on economic development than positive shocks.
Detecting Cable Force Anomalies on Cable-Stayed Bridges Using the STA/LTA Method
Authors: Wang Yanwei , Zhao Qingxu , Li Yuandi , Zhang Min , Zhu Wanxu
Published: September 2022

The cable force of cable-stayed bridges may become abnormal during operation, so cable force anomaly detection is essential for evaluating the health of cables. The current methods for detecting cable force anomalies have poor resistance to temperature disturbances and are insensitive to abnormal cable force, making it challenging to detect minor cable force anomalies. Therefore, this work employs the short-time-average over long-time-average (STA/LTA) method to detect cable force anomalies. The characteristic function and key parameters of the STA/LTA method are optimized and tested by combining measured cable force data with cable force anomaly simulation. The results show that the STA/LTA method can effectively mitigate the interference of temperature in the detection of cable force anomalies and that it has good sensitivity to minor cable force anomalies. By examining detecting the measured cable force data of the Xiangjiang Bridge in Dongzhou, Hengyang, China, it is further verified that the STA/LTA method could effectively detect a cable force anomaly with a cable force deviation rate of higher than 1%.

Published: September 2022

Residual biomasses from agro-industries in Paraguay, including soybean hulls (SBHs) and sugarcane bagasse (SCB), were studied as a source for nanocellulose extraction for the first time. For that purpose, both biomasses were delignified in a semi-pilot stainless-steel reactor, and the cellulose pulp was subjected to a bleaching process with NaClO (2.5%, w/v). The nanocellulose (CNC) was obtained after two-step acid hydrolysis. Firstly, the bleached cellulose was hydrolyzed with HCl (17%, w/w) for two hours at 60 °C to obtain microcrystals by removing most of the amorphous fraction. The celluloses were then treated with H2SO4 (65%, w/w) at 45 °C for 45 min to obtain nanocellulose. Physicochemical and morphological properties were analyzed using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray diffraction analysis (XRD). The SBHs nanocellulose had a whisker-like form with a 230 ± 42 nm diameter and a 12 ± 2 nm height, and the SCB nanocellulose had a fibril-like form with a 103 ± 30 nm diameter and a height of 6 ± 3 nm. The nanocellulose from SBHs and SCB had good thermal stability as its degradation temperature started at 250 °C. Furthermore, the nanocellulose obtained was negatively charged and formed stable dispersion in water at 0.1 mg/mL concentration and a pH of around 6.5.

Authors: Méndez David , Méndez Miriam , Anguita Juana María
Published: September 2022

Improving the digital competences of teachers, students, and schools contributes to achieving Sustainable Development Goal 4 of the 2030 Agenda. That goal consists in enhancing the quality of education and offering learning opportunities. The knowledge of digital resources that teachers had and used during the COVID-19 confinement has contributed to the current awareness of the need to improve teachers’ digital competence. The main objective of this paper is to analyse the digital resources that teachers participating in this research used the most in Spain between March and June 2020 due to the lockdown experienced in that country. A validated questionnaire, which was administered online in schools and high schools of the Community of Madrid, was answered by 97 teachers who were able to teach from home. The results reveal their assessment of the technological resources they used. In their opinion, the most useful were digital platforms, online classes, and videos, whereas the least useful were online tests and forums. Their answers also show that the training they received was mainly through Internet tutorials and consultations with colleagues. In order to ensure quality education, it is important to improve teachers’ digital competence as a part of their training.

Published: September 2022

Pakistan is not merely confronting the energy crisis but also dealing with the scarcity of economical technologies for the utilization of energy resources. From the basic resources, renewable energy is one of the considerable resources. Due to environmental issues related to greenhouse gases (GHGs) and air pollution in Pakistan, the other energy resources are constricted. In rural areas, biomass resources are a fundamental need for domestic purposes. The prominent reason for environmental degradation and deforestation is due to ineffective use of such resources. Biomass resources for heating and cooking purposes are abundantly available in rural areas of Pakistan. In this context, this study helps us select the applicable cookstove technologies for the Sindh province for the proper utilization of biomass resources. The AHP (analytical hierarchy process) was used as the central methodology for the cookstove ranking. Concerning its improvement, four main criteria corresponding to 12 sub-criteria were considered for the selection of three cookstove technologies, i.e., traditional cookstoves (TCS), efficient cookstoves (ECS), and biogas cookstoves (BCS). The final decision of the AHP framework exposed the ECS technology as the advantageous technology, followed by the BCS and TCS, respectively. To analyze the results, a sensitivity analysis of the major results has also been carried out, and under the final ranking matrix, the ECS alternative got the highest weightage, nearly 36.56%, based on the developed model.
The Impact of High-Speed Railway Opening on Regional Economic Growth: The Case of the Wuhan–Guangzhou High-Speed Railway Line
Authors: Ye Chong , Zheng Yanhong , Lin Shanlang , Zhao Zhaoyang
Published: September 2022

With the advent of the “ear of high-speed railways”, the space–time distance between cities has drastically decreased. The opening of high-speed railways has not only increased the factor-flow speed across regions, but has also reduced the cost of factor movement. However, there is some controversy about whether high-speed railways can be used to promote regional economic growth. The Wuhan–Guangzhou high-speed railway is the earliest section of the Beijing–Guangzhou high-speed railway, and it was the first high-speed railway in China with a real speed of 350 km per hour. The Wuhan–Guangzhou high-speed railway opening spawned a three-hour economic circle in the south of China, injected new vitality into the economic and social development along the line, and had an important impact on accelerating regional economic interoperability and integration. Taking this into account, this paper took the Wuhan–Guangzhou high-speed railway as the case study. Firstly, this paper used the theory of system dynamics to analyze the mechanism of the impact of high-speed railway opening on regional economic growth. Secondly, the accessibility model was used to analyze the impact of the high-speed railway opening on the accessibility of cities along the line, and a difference-in-differences model (DID) was used to explore the impact of the high-speed railway opening on regional economic growth. Finally, on the basis of the analysis of the previous mechanism, the mechanism of the impact of the high-speed railway on regional economic growth is discussed. The results of this study show the following: (1) Since the opening of the high-speed railway, the accessibility of cities along the line has grown by more than 60%. (2) The opening of the high-speed railway has promoted regional economic growth, mainly through the influence mechanism of “increasing the total cargo volume”. This study not only scientifically and quantitatively analyzed the impact of the opening of high-speed rail on regional economic growth, taking the Wuhan–Guangzhou high-speed railway as an example for empirical analysis, but also further summarized the high-speed railway construction achievements in China and provides reference experience for planning the opening of high-speed railways.
Promoting Personalized Learning in Flipped Classrooms: A Systematic Review Study
Authors: Cevikbas Mustafa , Kaiser Gabriele
Published: September 2022

Flipped classroom (FC) is a widely accepted, innovative pedagogy designated to enhance students’ learning by changing the paradigm of instruction. It has the potential to adapt learning to the students’ needs, interests, and mutual expectations by using the advantages of both online and face-to-face learning, which strengthens the quality of the instruction. The potential of FC to foster personalized learning (PL) has become vital in education, as individuals face different possibilities and difficulties in the learning process. To date, no systematic review study has focused on the ways in which PL occurs in FCs and the role of personalized FCs in education. The present study aims to close this gap by exploring the value of flipping instruction and strategies to support PL. We searched the literature, focusing on peer-reviewed research studies published in English that focus on PL in FCs. The key results include (a) the study characteristics, (b) the approaches developed and used in FCs to enhance PL, and (c) the role of personalized FCs in teaching and learning. Overall, this systematic review study provides insight into successful FC implementations and strategies to sustain PL.
Effects of Surface-Attached Vertical Ribs on Wind Loads and Wind-Induced Responses of High-Rise Buildings
Authors: Ke Yanyu , Shen Guohui , Yang Xiaoyue , Xie Jiming
Published: September 2022

Façade design tends to be diverse with increasing requirements for architectural functions in modern high-rise buildings, leading to various aerodynamic roughness conditions of the building surface. A typical practice is setting vertical ribs on the building façade. This study aims to clarify the effects of vertical ribs on the wind loads and wind-induced responses of high-rise buildings. The models with four vertical rib configurations were tested in the open and suburban exposures using the High-Frequency Force Balance (HFFB) technique in a wind tunnel. The base overturning moments and corresponding responses are demonstrated and compared between models and exposures. Results show that the vertical ribs with a relative width of 4% can not only reduce the mean force coefficients in the along-wind direction but also attenuate the cross-wind vibration by disrupting the regular vortex shedding. Moreover, the half-distributed and full-distributed rib configurations have almost indistinguishable benefit, indicating that the ribs in the corner region of the building façade play a dominant role in reducing the wind-induced responses. Although the cross-wind responses of the building would be less severe in the suburban exposure than those in the open exposure, the reduction rate of the wind-induced responses by the vertical ribs remains almost unchanged.
An Overview of Snow Water Equivalent: Methods, Challenges, and Future Outlook
Authors: Taheri Mercedeh , Mohammadian Abdolmajid
Published: September 2022

The snow depth or snow water equivalent affects water, carbon, and energy cycles as well as surface–atmosphere interactions. Therefore, the global monitoring of spatiotemporal changes in snow water equivalent is a crucial issue, which is performed by characterizing the macrophysical, microstructural, optical, and thermal characteristics of the snowpack. This paper is a review of the retrieval methods of snow water equivalent in three main categories, including in situ measurements, reconstruction approaches, and space-borne measurements, along with their basic concepts, advantages, and uncertainties. Since satellite observations are the most important tool used to detect snow properties, the paper focuses on inversion models and techniques using microwave remote sensing. The inversion models, based on various theoretical foundations, are classified into empirical, statistical, and physical (emission) models, and the techniques are described in four groups: iterative methods, lookup table, machine learning, and data assimilation approaches. At the end, the available global and regional gridded products providing the spatiotemporal maps of snow water equivalent with different resolutions are presented, as well as approaches for improving the snow data.

Feature selection is considered as one of the essential steps in data pre-processing. However, all of the previous studies on predicting PM10 concentration in Malaysia have been limited to statistical method feature selection, and none of these studies used machine-learning approaches. Therefore, the objective of this research is to investigate the influence variables of the PM10 prediction model by using wrapper feature selection to compare the prediction model performance of different wrapper feature selection and to predict the concentration of PM10 for the next day. This research uses 10 years of daily data on pollutant concentrations from two stations (Klang and Shah Alam) obtained from the Department of Environment Malaysia (DOE) from 2009 until 2018. Six wrapper methods (forward selection, backward elimination, stepwise, brute-force, weight-guided and genetic algorithm evolution and the predictive analytics multiple linear regression (MLR) and artificial neural network (ANN)) were implemented in this study. This study found that brute-force is the dominant wrapper method in most of the best models in selecting important features for MLR. Moreover, compared to MLR, ANN provides more advantages regarding model accuracy and permits feature selection in predicting PM10. The overall results revealed that the RMSE value for next day prediction in Klang is 20.728, while the AE value is 15.69. Furthermore, the RMSE value for next day prediction in Shah Alam is 10.004, while the AE value is 7.982. Finally, all of the predicted models in Klang and Shah Alam can be used to predict the PM10 concentrations. This proposed model can be used as a tool for an early warning system in giving air quality information to local authorities in order to formulate air-quality-improvement strategies.

Published: September 2022

In Kutch (Gujarat District, India), there is a growing concern about the lack of good quality forage owing to the arid climate and poor soil health. Opuntia ficus-indica has been increasingly recognized as a drought-resilient forage in arid Kutch. This study seeks to identify the maturity phase of cactus cladodes with the best forage qualities. Five accessions of spineless forage cactus (CBG, No. 1270, No. 1271, No. 1308, and Bianca Macomer) and three cladode maturity phases (young, intermediate, and mature) were examined in a randomized block design experiment in a 5 × 3 factorial arrangement. Although only mineral matter and total carbohydrate concentration were significantly different among the accessions, CBG showed better forage qualities than other accessions. Dry matter, organic matter, mineral matter, crude protein, ether extract, and total carbohydrate accumulations were higher in the intermediate phase. In the mature phase, relatively difficult to digest fiber components such as neutral detergent fiber, acid detergent fiber, lignin, cellulose, and hemicellulose increase. Our findings indicate that for spineless forage cactus grown in arid areas, the intermediate phase is the best phase to harvest cladodes for feeding livestock.
Encapsulating Secrets Using Lockable Obfuscation and a RMERS-Based Public Key Encryption
Authors: Simion Eduard
Published: September 2022

Lockable obfuscation, a new primitive that occurs in cryptography, makes it possible to execute arbitrary polynomial-sized functions and recover a secret under specific equality conditions. More concretely, if the function executed over a specific input produces an output that matches an expected target value, here denoted by a, some secret string of bits s is exposed. Written in algebraic terms, if f:X→A has the property that for some x,f(x)=a, s is revealed. This work explores the possibility for safely decrypting ciphertexts, and based on the recovered plaintext’s equality to a stored message, to reveal some secret. Concretely, this work provides a review of existing, well-known public key encryption schemes and argues for the efficiency of a new one relying on the ratio Mersenne hypothesis (RMERS), which is to be used in conjunction with a lockable obfuscator. This work explores the advantage conferred by this scheme, especially in the minimization of the branching program’s number of levels that need to be obfuscated. The drawbacks of such schemes are also pointed out, given that they currently require the LWE evaluations level-per-level, one output bit at a time.

Authors: Silva-Gámez Alexander Israel , Méndez-Prado Silvia Mariela , Arauz Andrés
Published: September 2022

Patent Box regimes are a tax relief incentive promoted by governments to encourage the R&D activities of enterprises. The literature developed on Patent Box is still examining the effects on certain economic variables. Thus, this research conducted a systematic review of the Patent Box literature since 2010 and applied regimes worldwide. For this aim, the authors developed a comprehensive systematic review using the PRISMA scheme, analyzed the main scientific characteristics with bibliometrix R-package, and prepared a summary table with the attributes collected from the Patent Box scheme applied worldwide. The findings showed that the Patent Box literature is focused on describing applications on countries and implications, analyzing its effects on company and country performance, or examining its influence on location choices. However, there is no definitive consensus on its effect on innovation or economic outcomes, which finally depends on the design of this scheme. As an applied tool, Patent Box is mainly used in European countries. This review and future updates could help as a reference monitor of the Patent Box mechanism.

Published: September 2022

Land-use changes in urban fringe areas are dramatic, and modelling and predicting land-use changes under different scenarios can provide a basis for urban development regulation and control. As an important part of Beijing’s urban fringe, Daxing District is representative of its land-use changes. Taking the Daxing District of Beijing as an example, this study selected two periods of land-use data in 2008 and 2018 and predicted land-use changes in 2028 and 2038 using the GeoSOS-FLUS model (geographical simulation and optimisation system–future land-use simulation) and Markov chain model, based on the simulation and validation of land use in Daxing District from 2008 to 2018. Meanwhile, three types of scenario simulations were carried out. The results in the future predictions show that: (1) under the natural development scenario, the area of construction land and grassland gradually increased, and the area of cultivated land, woodland and water bodies gradually decreased; (2) under the cultivated land protection scenario, the area of cultivated land remained largely unchanged, the area of grassland decreased before increasing, the expansion of construction land was curbed, and the area of woodland and water bodies increased slowly; and (3) under the ecological control scenario, the area of cultivated land, grassland, woodland and water bodies showed slowly increasing trends, with a small amount of cultivated land being converted to construction land. These results indicate that the setting of cultivated land protection and ecological control can limit the expansion of construction land to a certain extent. This study can provide a basis for the regulation of urban development in the Daxing District in the future.

Authors: Massimo-Kaiser Ines , Exenberger Hans , Hruschka Sabine , Heil Frédéric , Flora Matthias
Published: September 2022

Currently, most academic discourse looking at the advantages of Building Information Modelling (BIM) is kept very general. This article evaluates how the use of BIM affects social and economic aspects of seven different tunneling projects. The analysis is based on internal project documentation and on-site visits, resulting in the authors subjective perception. Due to a confidentiality policy given by ongoing projects, the official documentation is anonymised. On one hand, the social analysis considers teamwork aspects. On the other hand, the economic assessment considers the optimised use of resources. The conclusion shows that the correct and complete implementation of all methods and tools from BIM increase social and economic sustainability, optimising project delivery in tunneling. As a result, among other things, on par communication, teambuilding, and mutual appreciation contribute to an increased social sustainability. Economic sustainability is directly associated with resulting short distances within the team and easy communication and coordination. Consequently, this leads to faster problem solving and a streamlined project execution.
It’s Story Time: Unlocking the Learnings in Malpractice Settlements
Authors: Pilcher Charles , Graber Mark
Published: September 2022

Risk managers and the insurers with whom we work have the greatest opportunity in healthcare today to improve patient safety. Our most egregious mistakes become medical malpractice claims and lawsuits. Some of these go to trial where the outcome is public; however, the least defensible cases are settled without a trial. Almost every settlement includes a confidentiality or nondisclosure clause (NDC). Such clauses become “gag orders.” Providers who could learn from the mistake of a colleague do not, and the same mistake is repeated, often many times over.

The stories of these settlements are a rich source of learning, and it’s time to tell them—anonymously. No naming names, no disclosure of settlement amounts, no “blame and shame.” Stories are powerful, attention-grabbing, and memorable. Telling them is a unique opportunity to link the prevention of patient harm to the healing mission of healthcare and acknowledge the common wish of every plaintiff that “this won’t happen to someone else.”

Authors: Neiswender Kristin , Figueroa-Altmann Ana , Granahan Kristin , Barkman Darlene
Published: September 2022

Repeated culture of safety surveys of the nursing staff at Children’s Hospital of Philadelphia’s main campus demonstrated lagging scores in the domain of nonpunitive responses to error. We had tried for many years to address the problem using a variety of strategies, including small group training sessions on just culture for staff and leaders, but had met with limited success. Finally, in 2015, we committed ourselves to trying something genuinely different—even perhaps disruptive—that might actually shift our stagnant metrics. Our novel, multifaceted program, implemented over a two-year period, yielded a 13% increase in staff rating scores that we have been able to sustain over the subsequent two-year period. The design and rollout of our program was neither simple nor smooth, but it has taught us valuable lessons about realistic, operational implementation of principles of psychological safety in a large and complex clinical organization. In this paper, we describe our program and the lessons learned in the journey from idea inception to post-implementation.

Authors: Magalhães Benedita Neire Almeida de , Darsie Marta Maria Pontin
Published: September 2022

Este trabalho é parte de uma pesquisa de mestrado em andamento e foi concebido através de uma revisão bibliográfica cujos conteúdos evocam a Contextualização de Resolução de Problema e a Interdisciplinaridade no contexto da Educação Matemática Crítica. Objetiva-se identificar os teóricos e a abordagem da resolução de problema e a interdisciplinaridade. A metodologia de pesquisa empregada foi do tipo exploratória e informação sobre o assunto em estudo (CERVO et al. 2010). Os teóricos que nortearam: Freire (1996; 2006), Onuchic e Allevato (2004)), D’Ambrosio (2003), Polya (1981), Stanic e Kilpatrick (1989), Skovsmose (1992; 2001; 2008; 2013). Destarte que, a partir das teorias e o contexto histórico, evidenciou-se a relevância da metodologia de resolução de problemas e a interdisciplinaridade, na abordagem da educação matemática crítica para a prática educativa. Os resultados preliminares indicam que esta é uma forma de despertar o pensamento, a ação, a argumentação e o diálogo entre os alunos e propor soluções para o problema, de forma criativa, coletiva e autônoma.
RESEARCH OF METHODS FOR MEASURING THE PHYSICAL PARAMETERS OF THE FLUE GAS POSTCOMBUSTION TORCH IN OXYGEN CONVERTER

The oxygen-converter process is accompanied by the release of a significant amount of off-gases, that under the conditions of postcombustion form a torch over the neck of the converter. It is an additional source of heat in the converter. Change the torch nature corresponds the peculiarities of the heat blowing. However, it is difficult to register and analyze the torch due to the significant temperature above the neck of the unit and the large amount of dust released during the blowing. And, if small particles of dust can considerably heat up in real conditions of the converter and strengthen indicators of a torch, much bigger particles can interfere with it. It was conducted a physical modeling on a single gas torch of 250-300 mm particles of different chemical composition (corresponding to the oxygen-converter process) influence on the possibility to register the physical characteristics of the postcombustion torch: heat transfer, luminosity (brightness) and electrical characteristics. Visually, it was established that the direct supply of non-oxidizing solid particles to the burning torch turns the burning flame in yellow or yellow-orange color and the flame increases in size due to incomplete combustion of the fuel mixture compared to pure combustion (without dust). This manifestation is characteristic of particles of oxides of silicon, calcium and magnesium and iron (III) oxide. Particles that can be oxidized by contact with a burning torch, in addition to increasing the visible part, cause a significant increase in the visual brightness of the flame.

El proceso de escucha de la Asamblea Eclesial de América Latina y El Caribe (AEALyC), ha permitido recoger senti-pensares y anhelos profundos con relación a diversos temas que implican la vida del pueblo de Dios. Quienes participaron son personas de diferentes lugares, culturas, estados de vida, generaciones… buscando soñar y re-edificar un nuevo modo de ser Iglesia en el mundo. Este inédito esfuerzo trae consigo esperanzas y desafíos que posibilitan relacionamientos, encuentros, acogidas y, sobre todo, el cuidado de la vida humana-cristiana y cósmica. Así este trabajo ofrece algunas puntualizaciones y reflexiones que podrían aportar a la construcción de una Iglesia Sinodal.
"Derramaré mi Espíritu": el uso lucano de Joel 3,1-5 en Hechos 2,17-21
Authors: Gonzaga Waldecir , Pinheiro Martins Cláudio Márcio
Published: September 2022

El Nuevo Testamento (NT) contiene muchas citas, alusiones y ecos reportados del Antiguo Testamento (AT), porque los autores del Nuevo Testamento, a diario, usaban las Sagradas Escrituras judías, aunque de su versión griega, el idioma más usado entonces. El recurso de los autores del NT al AT fue tan común que los textos del Antiguo Testamento se encuentran en todas partes en los libros del NT. De hecho, incluso textos religiosos apócrifos y otras tradiciones, como la poesía y la filosofía. Los autores del NT, al utilizar textos del AT, en vista del propósito teológico a alcanzar, preservaron o modificaron el significado original de los textos, según el alcance teológico, como recurso o estrategia retórica. Algunos autores usaron un poco más y otros un poco menos, pero generalmente usaron mucho más de la versión griega que del texto hebreo. El presente artículo, haciendo uso del Método Histórico Crítico y del Análisis Retórico Bíblico Semítico, analiza el uso de Joel 3,1-5 en Hechos 2,17-21, citado íntegramente en el NT, algo raro, ya que es un capítulo completo de un libro del AT citado en un libro del NT. Busca comprender de qué fuente se citó el texto de Joel, si en su totalidad o si ha sufrido algún cambio, ya que el texto de los Hechos de los Apóstoles trae algunas diferencias textuales. Analiza tanto la fuente del Antiguo Testamento, sea en hebreo sea en griego, como el texto del Nuevo Testamento, con estructura y traducción, indicando los matices y la riqueza del uso de la profecía de Joel por el autor de Hechos de los Apóstoles.
Montañas sagradas de la Patagonia Meridional y Tierra del Fuego
Authors: Ceruti María Constanza
Published: September 2022

Los majestuosos picos nevados, torres graníticas y extensos glaciares han revestido de importancia simbólica y religiosa para los grupos originarios del sur de la Patagonia y Tierra del Fuego. Inspiraron relatos que vinculan a las montañas con héroes culturales, chamanes, guerreros petrificados, fuerzas atmosféricas y míticos diluvios. La autora realizó extensas marchas a pie hasta la base de las Torres del Paine, el macizo del Chaltén y el cerro Torre; además de caminatas en los glaciares Perito Moreno y Viedma. Fotografió sitios con arte rupestre en el área de las Torres del Paine y en la Cueva de las Manos del Río Pinturas. En Tierra del Fuego visitó concheros en Bahía Ensenada, Bahía Lapataia y Navarino, además de museos históricos y muestras etnográficas en Ushuaia. En estas páginas se pone el foco en la diversidad de leyendas y tradiciones culturales con las que los grupos canoeros y cazadores de guanacos de Tierra del Fuego y la Patagonia Meridional han representado y actualizado su relación simbólica con los picos y glaciares de los Andes Australes. Las perspectivas etnohistórica, etnográfica y antropológica se combinan con los estudios de campo sobre paisajes sagrados, para el análisis del papel que la montaña cumple en la mitología, las prácticas shamánicas y los ritos iniciáticos de los antiguos Yamanas, Onas y Tehuelches.
Comunicación para la comercialización de productos libres de gluten orientada a consumidores celíacos
Authors:   , Goretta José María
Published: September 2022

El presente proyecto de investigación tiene por objetivo ofrecer una perspectiva sobre los procesos de comunicación realizados por los hipermercados para comercializar productos libres de gluten teniendo en cuenta el capital cultural y conocimientos de los consumidores celíacos, para lo cual se ha tomado como referencia geográfica la ciudad de La Plata (Buenos Aires, Argentina). En un primer apartado, se detallan las características de la enfermedad celíaca, el cambio de escenario de acuerdo a los avances médicos, la actuación de las asociaciones de celíacos, el rol del estado, las variaciones en el escenario comercial con el incremento de opciones de productos alimenticios aptos, y la adecuación de los comercios para poder satisfacer la demanda de estos clientes con requerimientos particulares. Estos elementos contextuales sirvieron de base para la búsqueda del material teórico necesario para estructurar la presente investigación. Para el presente proyecto se utilizaron métodos cualitativos, consistentes en entrevistas semi estructuradas a referentes de asociaciones de celíacos y a responsables de las cadenas, observación en las tiendas y el análisis de material de comunicación de las empresas y sus correspondientes soportes. De este modo, se llevó adelante el objetivo de analizar y fundamentar una argumentación sobre cómo los hipermercados construyen la representación de este segmento de clientes, cuyos derechos como consumidores adquirieron mayor consideración a partir de la sanción y reglamentación de Ley Nacional de Celiaquía.
