Published: October 2022

The theory of boundedness of classical operators of real analyses on Morrey spaces defined on Carleson curves has made significant progress in recent years as it allows for various applications. This study obtains new estimates about the boundedness of the maximal commutator operator $M_b$ and the commutator of the maximal function $[M, b]$ in Morrey spaces defined on Carleson curves.
On Parametric Surfaces with Constant Mean Curvature Along Given Smarandache Curves in Lie Group
Authors: KUCUKARSLAN YUZBASİ Zuhal , TAZE Sevinç
Published: October 2022

This paper finds sufficient conditions to determine a surface whose mean curvature along a given Smarandache curve is constant in a three-dimensional Lie group. This is accomplished by using the Frenet frames of the specified curve to express surfaces that span the TN, NB, and TB Smarandache curves parametrically. In terms of the curvatures of given Smarandache curves, marching scale functions, and their partial derivatives, the mean curvatures of these surfaces along the given TN, NB, and TB Smarandache curves are determined. Sufficient conditions are found to maintain the provided mean curvatures of the resulting surfaces at a constant value. Finally, some examples are provided.
Future Competencies and E-Tutor Competencies: A Chance for Higher Education Institutions to Support Their Student Staff
Authors: Langesee Lisa-Marie
Published: October 2022

Purpose: E-tutors often participate in collaborative online international learning (COIL) settings and guide students in group work and related learning processes. They moderate, organize, and observe the group and individual learning processes and are often students’ first point of contact. This support requires several competencies, which are also largely reflected in the so-called future skills. Thus, it seems sensible to examine these competencies more closely and promote them to enhance the course experience and support for students in COIL settings on the one hand and to make student e-tutors fit for the modern working world on the other.
Study design/methodology/approach: As a starting point for this project, a comprehensive systematic literature analysis on e-tutor competencies and qualifications was conducted in Langesee (2023). A competency ranking and task-based competency profile for e-tutors in higher education were developed during this research. To investigate the validity and practicability of these artifacts, an evaluation was conducted with 16 international experts and practitioners (e-tutors) using a questionnaire.
Findings: The competencies identified in Langesee (2023), the ranking, and the profile created were recognized as helpful and practical. Additional comments from respondents allowed both artifacts to be revised and expanded. The three most relevant competencies of the nine detected are communication, pedagogical and social competencies.
Originality/value: The resulting artifacts can be used in the next step as a basis for a self-evaluation tool (SET), enabling e-tutors to assess their competence equipment. Based on this, individual instruments will be recommended to initiate possible improvements.

Este artigo analisa a percepção dos gestores de saúde sobre os domínios técnico e operacional do gerenciamento de equipamentos médico-assistenciais nas policlínicas regionais, administradas por consórcio público no estado do Ceará, Nordeste do Brasil. Pesquisa qualitativa, realizada entre os anos de 2017-2018, com 11 gerentes de policlínicas. A coleta deu-se por entrevistas gravadas e transcritas na íntegra, norteadas sobre desafios de gerenciar equipamentos na atenção secundária. Os dados foram organizados no software QSR NVivo e submetidos a análise de conteúdo, originando três categorias temáticas: Mantendo tecnologia viva; Refém dos custos e das empresas de manutenção; Falta de monitoramento dos equipamentos, discutidas com base nos pressupostos da teoria da Racionalidade Limitada. As percepções convergiram sobre dificuldades devido ao alto custo, desarticulação entre a oferta e demanda, dependência tecnológica técnica-operacional, escassez de qualificação profissional, limitando as decisões gerenciais. Diante das incertezas nos cenários constituídos, o gerenciamento limita-se a buscar soluções satisfatórias, momentâneas, para manter a continuidade do serviço.

Published: October 2022

The current status of the digitalization process in Kosovo has begun to show the first clear signs of contradictory phenomena. A considerable number of document management systems have been entered, especially in the state administration system. Along with evident benefits, there are problems with the compatibility of the new systems with the existing paper work system. Harmonizing the availability of documents and work methods is not an easy task. Some documents, in spite of being in a digital version, must remain on paper. The digitalization costs are high and the said problems cause significant delays in implementation. This paper shows potential technological solutions that enable sustainability of the digitalization process through lower costs.

El contexto digital de las nuevas reformas universitarias
Authors: Rama Claudio
Published: October 2022

En el ensayo se analiza que estamos ante una transformación social dada por la irrupción de una dinámica digital de los procesos de trabajo. Esta a su vez deriva de cambios en el conocimiento y en las tecnologías de la información y de la comunicación. Esta sociedad digital impulsa el crecimiento económico, lo cual crea el desafío de promover la digitalización como palanca del desarrollo. Dicha transformación en curso promueve la creación de sociedades del aprendizaje, para permitir la mayor dotación de recursos humanos, la innovación y la especialización de las competencias laborales. Esta disrupción digital de la sociedad está siendo acelerada por las «pandemias » y deriva en una nueva y muy amplia reforma universitaria centrada en la incorporación de una educación digital híbrida. En el artículo se sostiene que ello es parte de una reforma de la diversidad y que esta innovación estructural en la organización de la enseñanza no se limita al uso de modalidades articuladas, sino que, además, implica cambios en el rol del docente, quien pasa a cumplir la función de mentor de un aprendizaje con fuerte incidencia de las TIC. Sin embargo, se plantea que la velocidad del cambio crea también resistencias que marcarán el curso final de estas reformas en desarrollo, las cuales se despliegan en el nuevo escenario de los poderes en el mundo digital, que es más efímero y débil.

Hardened Borders: A Case Study on Inefficient Solutions to the Immigration Problem in El Paso
Authors: Erb Caroline
Published: October 2022

With the rising controversy over illegal immigration, Mexican migration to the US twirls into the spotlight. In 2005 the majority (56 percent) of the 11.1 million unauthorized aliens were of Mexican origin (Passel i)—a signal to the US government that the source of the problem is illegal Mexican migration. The solution pursued in the last two decades by the US government was the fortification of the US-Mexico border. The following article argues that hardened borders between the US and Mexico are not a viable solution to unauthorized Mexican migration. The fallacies of the framework for immigration since 1986 are examined by means of a conducted case study on the borderplex of El Paso and Ciudad Juárez. The case study illustrates the social, economic, and kinship cross-border ties which contribute to the porosity of the border. Furthermore, it investigates stepped-up border enforcement programs, such as Operation Hold-the-Line, and new modes of entry resulting from the US Customs and Border Protection’s latest strategies to deter illegal migration.
Translating Idiomatic Expressions in Literary Texts Saving the Pragmatic Meaning
Authors: Alabdali Tahani
Published: October 2022

This paper investigates a problematic issue in many texts, particularly literary, that is of rendering hidden pragmatic meanings of idiomatic expressions into the TL. In order to arrive at the best strategy to do so from the perspective of the TL audience, in this case native speakers of English, the researcher provided the targeted audience with multiple translations of a single idiomatic expression, in context, and asked them to choose the best suiting translation from their point of view. Baker's strategies for translating idioms was the framework adopted for this study (Baker, 2018). The findings emphasized the importance of conveying the pragmatic meaning of idiomatic expressions with reservation of the aesthetic elements of the text. They also suggested that pragmatic and cultural highlights, in addition to translation strategies curricula, should be part of translation training programs.

The representatives of The main character were multiplied in it, according to information abundance and events going around explicit character in the narrative , (Yacob Al-Arian) is the hero of the story. This character has been repeated by Al-Gosaibi in more than one story, that is likely linked to the implicit connotations intended by the author. According to several indications, mentioned in the context, Al-Gosaibi / the narrator is himself one of the heroes of this story as he met the heroisms of (Yacob Al-Arian) in more than one point and across more than one level. His philosophy, culture, and sometimes his life events have influence on his narration in a clearer manner than any other neutral author. It is a view that goes along with some other controversial facts emerging in the literal character of Al - Gosaibi concerning his novels and their relation to his biography. Destiny also played the leading role of heroism in the story according to the induction of other indicators that made a logical hypothesis about the influence of destiny in characters and their conditions, and its role in triggering story events, which are probably pointing to intentional care by the author(Al-Gosaibi).
The Refutation of the Concept of Unanimity in the Arabic Grammar: A Genuine Study on the Refutation of Abu-Hayyan's on Ibn Malik's Unanimity
Authors: Al-Lahim Ibrahim
Published: October 2022

This research lies within the framework of theoretical grammar as it examines a fundamental intellectually theoretical issue; that is, the refutation of the narrative of consensus. Therefore, it explores the concept of consensus and its refutation, the invariability of consensus towards refutation, and the validity of consensus in the theoretical grammar framework. Moreover, it studies variations in terms of concept and differences in applications. Then, it illustrates some theoretical bases of the grammarians' procedures for the evidence of consensus. Later, it demonstrates some applications on refutation as in ibn Hayyān,s tracing of Ibn Mālik and his refutation of consensus in a number of issues narrated by Ibn Mālik, and examines these issues and shows the extent to which refutation has occurred. Grammarians have varied in defining the concept of consensus as a result of variations and differences in opinions in two cases; first, location of denial: on rules or on interpretations, or on both; second, determining the time of consensus. As a result of the differences of opinions, some narratives have vanished and others remained.

Published: October 2022

Synthetic rainfall is needed as an input in the analysis of design flood. This research intends to conduct the verification of a synthetic rainfall model based on the ArRR and satellite result. The rainfall data is as the main component in obtaining the design, detail design, operation and maintenance of effective water resource infrastructure. Rainfall data is often used for the analysis of flood balance, flood frequency distribution, estimation of river discharge, and design of water structure. However, the main constraint in designing the water resource infrastructure is less available rainfall data temporally and spatially. The limitation of available rainfall station number causes inaccuracy in analyzing the area mean rainfall. Therefore, sometimes the correlation between recorded data from the rainfall station and water estimation station does not show a positive and strong correlation. This is due to less rainfall data that are spatially representative in the watershed upstream. The verification is carried out in the Ciliwung Hulu watershed. The methodology consists of ArRR analysis of the two extreme rainfall events, then the ArRR is analyzed using the synthetic rainfall model equation that is applied for watershed areas < 750 km2; in the end, we spatially compared the satellite and observed rainfall. The analysis of the ArRR value is based on the formulation as follows: ArRR_i=(0,026FB-0,307*Re_i+1,184 Q_(i+lag)/A+0,693)/(C_ArRR.K_ArRR ). The lag time that is used is 3 h based on the analysis of time to peak by using the Nakaysu hydrograph by assuming that the run-off coefficient is 0.35. The spatial comparison between satellite and observed daily rainfall on February 19, 2021, and October 28, 2021, shows that the rainfall distribution pattern is more similar with adding the ArRR synthetic rainfall station than with only using the ARR station.

Published: October 2022

Data obtained from the drive-test in the urban area (a case study of Siliwangi Stadium, Bandung) revealed that the low throughput occurred on the downlink, which was 3.56 Mbps. On the uplink, it was 20.7 Mbps. Additionally, based on the Operating Support System (OSS) data, the site had high resource block usage (80% of PRB usage). It revealed the high traffic volume in the area, which resulted in poor throughput values received by users. The area is one of the potential market areas in the city of Bandung, which is indicated by housing, military area command education and training regiment, schools, hotels, markets, and stadiums. Based on the Site Database (SDB), it was known that the site has not yet implemented the carrier aggregation method. This study evaluated throughput using the Inter-Band Non-Contiguous Carrier Aggregation method by comparing three scenarios: Non-CA, CA Non-Repeater, and CA Repeater.

Published: October 2022

Increasing economic growth is always a big concern for all countries over the world. The paper applied the 2SLS model for the secondary panel data of 49 high-, middle-, and low-income countries for 20 years (2000 – 2019) to investigate the influence of monetary policy, government effectiveness, and other control proxies on economic growth. In this study, the authors measure the monetary policy by two variables, named “Interest expense” (IE) and “Compensation of employee expense” (CE). This research evaluates the government effectiveness by two factors, specifically “Tax revenue” (TR) and “Control of corruption” (CC). The research also uses two control variables: “Rural population” (RP) and “Trade openness” (TD). The findings confirm that monetary policy, trade openness, and control of corruption are three significantly beneficial factors that promote income per capita. However, rural population rate, and tax revenue are harmful factors for economic growth. Additionally, the GMM model also supports the same results as the 2SLS model. By investigating the monetary policy via interest and compensation of the employee expense and the role of the Government for economic growth, the study contributes to the monetary policy seen as follows. Firstly, this study confirms that monetary policy has the positive effects on economic growth. Secondly, this research also confirms that government effectiveness has complex impacts on an economy based on the type of measurement of government effectiveness.

At present, to determine the residential type in a housing development project requires the experience and expertise of the project developers. This research aims to apply the Decision Tree Analysis to help analyze the residential type that will make the subdivision project achieve a good sales rate. The research process was conducted by collecting data from 179 residential subdivision projects from the market reports of real estate companies in Thailand, and then selected those projects with higher average monthly sales rates than those of all projects. A total of 59 projects were selected, comprising 31 townhouse, 22 detached house and 6 semi-detached house projects. Data for each project were collected. Then, these data sets and factors were analyzed using the Decision Tree Analysis. The results showed that the factors used in determining the residential type were the distance from the bus stations, land appraisal value and distance from parks. The model has an accuracy of 81.82% and is useful for those involved in the real estate development industry because it logically shows the decision- making process. It also demonstrates the potential for applying machine learning technique, as a technological innovation, to create models that aid real estate development decisions related to the customer’s behavior.
Driving Forces of the Epidemic: A Polluted and Polluting Planet
Authors: Landrigan Philip J.
Published: October 2022

Nearly 20 million new cancer cases are diagnosed across the world each year. By stressing that the majority of cancers can be prevented, Philip Landrigan focuses on the troubling consequences of pollution on individual, social, and planetary health. Since 1990, reduction has occurred in the traditional forms of pollution associated with deep poverty and in the numbers of deaths caused by these forms of pollution. But the modern forms of pollution–ambient air pollution and chemical pollution–are on the rise, as well as the numbers of deaths due to these forms of pollution. Moreover, the health consequences of pollution are inequitably distributed, with the most significant increases in cancer incidence and mortality occurring in low- and middle-income countries–i.e., the countries least capable of confronting the disease and least well able to afford costly therapies. Finally, the author suggests science-based strategies for pollution control and cancer prevention.

Published: October 2022

In this paper, we investigate the influence of financial proxies on companies in the real estate sector listed on the Amman stock exchange during the Covid-19 pandemic. A panel data method is employed for the sample, which includes 29 listed real estate companies, for the period from 2010 to 2020. The financial proxies are considered as independent variables, which consist of earnings per share, book value per share, price-to-earnings (P/E) ratio, price-to-book value, debt ratio, and current ratio, while the market return is the dependent variable. The results revealed that all financial proxies have a significant impact on market returns. Furthermore, the financial proxies are positively and significantly correlated with market returns. The results also showed that the Covid-19 pandemic negatively affected the real estate sector returns. Decision makers in real estate companies are required to manage their working capital in an effective and efficient manner in order to deal with unforeseen short-term events as investors might use historical financial data to estimate companies’ returns.

Google, Intel en de AEC-test – verwarring ontrafeld

Naar aanleiding van de recente uitspraken van het Gerecht in Google Shopping en Intel bekijken we in dit artikel de rol van de as efficient competitor-test tegen de achtergrond van de op effecten gebaseerde benadering bij mogelijk uitsluitingsgedrag. Volgens deze benadering zijn gedragingen van dominante ondernemingen die ertoe leiden dat inefficiënte concurrenten de markt verlaten niet mededingingsbeperkend als consumenten hierdoor niet geschaad worden. De as efficient competitor -test vormt voor prijsgerelateerd gedrag een nuttig hulpmiddel binnen dit kader.
