Published: February 2022

Traditionally, music teaching has been developed in person, however, during the last years and after the appearance of the pandemic (COVID-19), it became necessary to adopt new models based on virtuality and thus continue with the teaching-learning process. This work aims to identify the most deficient aspects in the instructional design (ID) of the classes of Instrumental Ensembles and the theoretical ones of the music in conditions of virtuality in the Academic Unit of Arts of the Autonomous University of Zacatecas, Mexico. Essentially, a comparison was made in the development of the process and the academic results achieved by the students in each type of classes to determine which elements of the ID must be perfected for the continuity of the subjects from the virtuality.
The singing teacher. Comparison between the 20th century teacher and the corresponding evolution in the current 21st century
Authors: Lima-Solanye Caignet , Chavez-Acuña Samuel Caleb , Bautista-Acosta Edgar Enoch
Published: February 2022

The figure of the institutional singing teacher is one of the most complex and undefined within the lyrical academic scene. The complexity of the instrument is already enough to make the task of the difficult master, since it is an impalpable and invisible instrument but with a special delicacy and treatment. The singing teacher from past times has worked with a fixed methodology that has given determined results. Today the contemporary teacher works differently, with the use of technology and the use of ICTs. Both figures have cultivated the emotional and psychological development of their students regarding Singing. In this research, the teaching figure was analyzed in an integral way, having as objectives the analysis of its evolution from the institutional and private perspective, the comparison between the fundamental differences of both figures and the continuous contribution and research of academic-artistic fields for the Singing area in general. It was found, through a comparative table, that the teacher of the so-called "old school" handled other concepts suitable for their social context but that they have several essential quality elements for the correct learning of the vocal technique, as well as the best phoniatric knowledge and physique that many contemporary teachers expose in the classroom.
Post-Pandemic Remote Supervision and Evaluation in Higher Education Academic Programs
Authors: Rivera Gutiérrez Erika , Higuera Zimbrón Alejandro
Published: February 2022

The aim of the research presented is to implement the process of evaluation and remote supervision of academic programs (AP) of the Incorporated Institutions (II) to a Mexican University, through a integral information system to record the level of compliance with each of the quality indicators and standards. It is justified from a gap in the post-pandemic remote academic-administrative evaluation and supervision process, for the fulfillment of curricular criteria and indicators, by not incorporating the use of ITC in these processes through an information system for the adequate supervision of AP. The methodological design focuses on a qualitative, exploratory-descriptive study, a case study method, with a non-probabilistic sample of 10 higher education institutions. The results show the need to incorporate ITC in these processes, to systematize the information for both face-to-face and remote processes. Consequently, a Integral System of Evaluation and Academic Supervision for Higher Education was developed that allows obtaining efficient results systematically and permanently from the evaluation and supervision of the AP of II, to record the level of compliance of each one of the quality indicators and standards.

De lo público a lo común: movimientos ciudadanos contra la mercantilización del patrimonio cultural
Authors:   Universidad Autónoma de Zacatecas, González Hernández Guadalupe Margarita
Published: February 2022

El patrimonio cultural, en su condición de objeto, cosa, es un bien y, por tanto, sus propietarios pueden hacer de él un medio para obtener ganancias monopólicas bajo la extracción del plusvalor creado por el trabajo colectivo. Pero las prácticas, ritos y percepciones que se crean alrededor de él, incluso los conocimientos y las relaciones sociales que lo originaron, forman parte de la comunidad, son lo común. Y eso es precisamente lo que debe rescatar el movimiento ciudadano, para considerar el patrimonio cultural como un bien común, como una propiedad no estatal y tampoco privada; es decir, lo inalienable que debe ser recuperado y apropiado por la comunidad.

Sobre las universidades
Authors:   Universidad Autónoma de Zacatecas, Espinosa Proa Sergio
Published: February 2022

El dominio implacable del capital, el Estado y la tecnociencia se cierne sobre la universidad y la cultura en general. El signo de los tiempos concede el triunfo a la mediocridad representada por la que dice ser la eficiencia y el éxito se prescribe en clave empresarial. Las universidades están sometidas a la razón instrumental, la burocratización y la falta de perspectiva. Pareciera que tienen la obligación de justificar su existencia ante el Estado, que por su parte no rinde cuentas claras a la sociedad. Pero las universidades representan en buena medida la visión, el diálogo y el pensamiento de la sociedad; en vez de hallarse postradas deberían de fiscalizar el funcionamiento de las agencias estatales desde una perspectiva ética y política.

Authors: Parudani Iyehezkiel , Effendi Taufiq , Rahmi Gita , Syafrudin Syarifah Azharina
Published: February 2022

Mobile-assisted Language Learning (MALL) has been globally popular. Yet, experimental studies investigating the results of different treatments between additional MALL and standard MALL implementations in Indonesian university context are still understudied. This research sought to investigate the extent to which additional MALL activities as a treatment to an EFL experimental group of university students could improve their English given the limited class time and large sized classes. The subjects of this study were two second semester classes of English Literature students. The experimental class, a low-performing group, was asked to watch a youtube video twice or thrice a week in addition to the standard online learning during the Covid-19 pandemic while the controlled class, a better performing group, was not given this treatment. The findings revealed that (1) experimental students significantly improved their pronunciation, intonation, vocabulary and fluency but not their formal assessment results; (2) though assigned additional MALL activities, the experimental group, due to limited financial ability for internet, spent roughly as much time as the controlled group; ((3) bad internet connection and low economic affordability contributed significantly to the less satisfactory result of MALL; (4) due to the standard online learning during the pandemic, both experimental and controlled students experienced increased exposures, enthusiasm, motivation, range of independent activites, autonomy and English ability; (5) real time students’ collaboration is challenging. This study suggests that MALL somehow allows greater English improvement and autonomy development and therefore is recommended that universities and respective local governments especially in remote areas provide the necessary supports.

Authors:   School of Economics, Can Tho University, Vietnam, Khong Tien Dung , Huynh Xuan Thi Dan ,   School of Economics, Can Tho University, Vietnam
Published: February 2022

Abstract Purpose: This study aims to estimate households' willingness to pay (WTP) in the Mekong River Delta for the improvement of solid waste (SW) management and identify factors influencing willingness to pay for the improvement program. Then, based on the results, this research proposed some policy implications for better SW management. Research methodology: The research employed both Contingent Valuation Methodology - CVM employed parametric and non-parametric approaches to estimate WTP and Logit model to identify the determinants of WTP. Results: The results from a random survey of 400 observations from 3 main cities in the Mekong River Delta (MRD) indicate that households’ willingness to pay level is from 86,000 Vietnamese Dong (VND) to 110,000 VND/month/household for the non-parametric and parametric approach, respectively (US$1 was equal to 22,890 VND on June 30th, 2021). The results also determine the factors influencing the decision to pay for the program, including bid level, households who have already classified waste, households who intend to support the program, and households’ income. Limitations: In future research, survey areas should be expanded to other developing countries in order to compare and provide a base for proposing better waste management programs in developing countries. Contribution: Future studies should apply both approaches to check the consistency of willingness to pay value elicited. Besides, in order to encourage households to participate in the waste classification program, the authorities need to raise awareness and encourage higher-income households to participate in advance.

Sparse Channel Estimation From Discrete-Time Fourier Transform Beam Measurements
Authors: Kapetanovic Dzevdan
Published: February 2022

In this paper, we study channel estimation at a uniform linear array (ULA) with $N$ antennas, where the channel at the ULA is composed of $L$ scatterers incoming from $L$ different angles of arrival (AoAs). It is assumed that Discrete-Time Fourier Transform (DTFT) beams (also known as \emph{analog} beams) are applied at the ULA to project the incoming signal onto a single (or multiple) RF chain(s), after which the signal is sampled and measured in baseband domain. This measurement procedure arises in various communication systems, such as the receive beam sweeping phase in 5G NR, where DTFT beams are used due to their simple implementation as linear phase shifts on analog antennas. A fundamental question about this procedure is the number of DTFT measurements necessary to recover the $L$ AoAs. Previous work on this problem showed (by applying compressed sensing theory) that $L\mathcal{O}(\log(N/L))$ measurements are sufficient for recovering the AoAs, which grows large for large $N$. Instead, by using properties of DTFT beam projections, we are able to show that if $N \geq 2L$, then $3L$ arbitrary DTFT measurements are enough; hence, dependency on $N$ is completely removed. The main reason for this drastic improvement is that sparsity is found in a \emph{non-linear} mapping of unknowns to observations, while compressed sensing deals with \emph{linear} mappings of unknowns to observations. Furthermore, if the DTFT beams are centered at harmonic frequencies (resulting in DFT beams) with period $N$, then $2L$ beam measurements are enough. With these results, an AoA estimation algorithm is formulated which has enormous complexity savings compared to $L$-dimensional AoA search such as maximum likelihood (ML) estimation. Numerical simulations demonstrate the algorithm's superior performance over a conventional algorithm. 
ElectrodeNet – A Deep Learning Based Sound Coding Strategy for Cochlear Implants
Authors: Huang Enoch Hsin-Ho , Chao Rong , Tsao Yu , Wu Chao-Min
Published: February 2022

ElectrodeNet, a deep learning based sound coding strategy for the cochlear implant (CI), is proposed to emulate the advanced combination encoder (ACE) strategy by replacing the conventional envelope detection using various artificial neural networks. The extended ElectrodeNet-CS strategy further incorporates the channel selection (CS). Network models of deep neural network (DNN), convolutional neural network (CNN), and long short-term memory (LSTM) were trained using the Fast Fourier Transformed bins and channel envelopes obtained from the processing of clean speech by the ACE strategy. Objective speech understanding using short-time objective intelligibility (STOI) and normalized covariance metric (NCM) was estimated for ElectrodeNet using CI simulations. Sentence recognition tests for vocoded Mandarin speech were conducted with normal-hearing listeners. DNN, CNN, and LSTM based ElectrodeNets exhibited strong correlations to ACE in objective and subjective scores using mean squared error (MSE), linear correlation coefficient (LCC) and Spearman’s rank correlation coefficient (SRCC). The ElectrodeNet-CS strategy was capable of producing N-of-M compatible electrode patterns using a modified DNN network to embed maxima selection, and to perform in similar or even slightly higher average in STOI and sentence recognition compared to ACE. The methods and findings demonstrated the feasibility and potential of using deep learning in CI coding strategy.

Impermanent Loss and Gain of Automated Market Maker Smart Contracts
Authors: Kim Hyoung Joong , Choi Soohyuk , Yoon Yong Tae , Yoo Shiyong
Published: February 2022

Smart contract is an important building block of blockchain. Automated
market makers are working without an order book, and they determine the price
of assets automatically. It is reported that he automated market makers have
the impermanent loss, which causes financial damage to liquidity providers.
Impermanent loss makes the liquidity providers hesitant to deposit assets in
the liquidity pool. Therefore, their participation incentive from liquidity
provision should be anticipated by automatic market makers inherently. However,
the existence of impermanent gain has never been reported. Impermanent gain is
important to attract liquidity providers without giving compensation incentives.
This study shows that for some automated market makers, impermanent gain
coexists with impermanent loss. Examples showing the coexistence and conditions
are provided.

Authors: Ünalan Değirmenci Beyza , Eskitaşçıoğlu Murat
Published: February 2022

Objective: The current study aimed to evaluate the life quality of implant-assisted mandibular overdenture patients who have had additional implant applications and were rehabilitated with ball or bar attachment.
Material and Methods: 53 patients who came to Van Yüzüncü Yil University, Faculty of Dentistry, Prosthodontics Clinic for implant-supported mandibular overdenture treatment between 2019 and 2021 were included in this prospective clinical study (32 females, 30 males; mean age: 64.03; age range: 33-90). The patients were called back for the study precisely one year after prosthetic loading of their implants. Implant-supported mandibular overdenture prosthesis patients diverged into six groups: splinted two implants (bar attachment), single two implants (ball attachment), splinted three implants (bar attachment), single three implants (ball attachment), splinted four implants (bar attachment) and single four implants (ball attachment). And they asked for completing the Turkish version of the OHIP-14 questionnaire.
Results: Ball attachment was used in 45.28% of the participants, a mandibular overdenture design supported by a bar attachment was preferred in 54.72%. Kruskal-Wallis test results indicated that the number of implants had a statistically significant effect only on functional limitation and psychological disability among the seven OHIP-14 categories evaluated (p=0.018, p=0.009). Accordingly, the average functional limitation score in individuals with four implants was 4.44 ± 1.89.
Conclusion: We found that there are a positive correlation between the number of implants and the patient's life quality; however, it can be concluded that attachment type does not significantly affect the scores of the life quality

A review of digital twin applications in construction
Authors: Madubuike Obinna C. , Anumba Chimay J. , Khallaf Rana
Published: February 2022

The emergence of digital twin technology presents tremendous opportunities for several industry sectors. A digital twin is defined as the virtual representation of a physical asset that collects and sends real-time information. A digital twin collects data from the physical asset in real-time and uses this data to create a virtual model of the physical object. Its functionality depends on the bi-directional coordination of data between the physical and virtual models. This is likened to cyber-physical systems, which seek to provide bi-directional coordination between the physical and virtual worlds. While digital twins have found applications in the various industrial sectors such as aerospace, manufacturing, and industrial engineering, their applications in the construction industry are relatively limited. Although some level of progress has been made in the construction industry with the application of a digital twin, it still lags in other sectors. Virtual models of constructed facilities are developed and used to plan and construct the actual facility, with changes in the physical facility being automatically reflected in the virtual model based on real-time data and vice-versa. The digital twin shows promising possibilities in the design, construction, operation, and maintenance of a facility. This paper reviews the development and implementation of digital twin technology in the construction industry and compares its use with other industries while assessing the benefits of DT to the construction industry. A systematic literature review including a thematic analysis was employed to address the purpose of this study. Limitations associated with the existing and emerging applications are also identified. It concludes by highlighting the importance of DT applications in the construction sector.

Gender diversity is an essential aspect of both private and public organizations. The concept has continued to evolve because of the need to tap into different abilities possessed by different gender at the workplace. However, previous studies have not indicated to what extent workforce diversity is related to employee performance in various organizations. On this basis, the paper sought to investigate the relationship between gender diversity and employee performance in the County Government of Bomet, Kenya. The paper was guided by social identity theory. The study adopted a correlational research design, and the target population was 3,320 employees working in various departments within the County Government of Bomet. Fisher's formula was used to determine the sample size for the study, which was 91. Data was collected using a structured questionnaire. The reliability of the research instrument was examined through the use of Cronbach's alpha coefficient, where an alpha coefficient of 0.850 was obtained. Content and construct validity of the instrument validity were ensured through extensive literature review and consultation with human resource management subject experts. Data analysis was done using correlation and regression analysis. Data were presented using frequency tables, means, and standard deviation. According to the study results, it was revealed gender diversity revealed a positive relationship (r=0.689; p<0.05) with employee performance. In general, gender diversity influenced employee performance by 72.3% (R2= 0. 723). According to the study findings, it was recommended that county governments ought to advocate for workforce diversity, explicitly focusing on gender diversity to increase employee performance.

Drama and theatrical performance remain one of the most effective ways through which life’s reality can be experienced, described, perceived and portrayed. Absurd drama has come to be seen as one of the most modern literary movements that have been adopted by African playwrights, Ruganda included. Based on a study of plays by Ugandan playwright John Ruganda, this paper discusses the philosophy of dissimilation, meaninglessness and isolation in theatre of the absurd. The study used Ruganda’s two plays, namely The Floods and Shreds of Tenderness. The various modes through which absurd drama appeal to the aesthetic sensibilities were examined. The study employed descriptive research and used purposive sampling. Data was analysed qualitatively by describing the findings of the study to arrive at inferences and conclusions. In Ruganda’s plays, the country is represented as being sick and in dire need of an urgent remedy but no one has the desire to bring in a solution to it. The sickness has not only affected the people as individuals but the nation as a whole. The playwright is by extension pointing to the cause of the sickness affecting the nation as being attributed to bad leadership. Using the lives of main characters, the playwright also demonstrates the senselessness of the human life and the inadequacy of the rational approach by the open abandonment of rational devices and discursive thought. The characters are portrayed as isolated and lonely individuals whose lives and fate area mere subject of time. The finding of the study is an important contribution to understanding drama and the changing trend in literary criticism in drama
Oxidative stress in obesity and insulin resistance

Since obesity is one of the main factors in the development of insulin resistance (IR) and is also associated with increased oxidative stress (OxS) rate, this study aims to review the published literature to collate and provide a comprehensive summary of the studies related to the status of the OxS in the pathogenesis of obesity and related IR. OxS represents an imbalance between the production of reactive oxygen and nitrogen
species (RONS) and the capacity of the antioxidant defense system (AOS) to neutralize RONS. A steady-state of RONS level is maintained through endogenous enzymatic and non-enzymatic AOS components. Three crucial enzymes, which suppress the formation of free radicals, are superoxide dismutases, catalases, and glutathione peroxidases. The second line of AOS includes non-enzymatic components such as vitamins C and E, coenzyme Q, and glutathione which neutralizes free radicals by donating electrons to RONS. Emerging evidence suggests that high RONS levels contribute to the progression of OxS in obesity by activating inflammatory pathways and thus leading to the development of pathological states, including IR. In addition, decreased level of AOS
components in obesity increases the susceptibility to oxidative tissue damage and further progression of its comorbidities. Increased OxS in accumulated adipose tissue should be an imperative target for developing new therapies in obesity-related IR.
