An evaluation of school directors’ organisational creativity and managerial effectiveness
Authors: Ozkan Timucin , Tokel Aytaç
Published: December 2020

Technology is gradually becoming a crucial factor in reaching educational targets. A person undertaking managerial responsibilities should possess managerial efficiency characteristics and exhibit them as well. The critical thinking process exists in all affective and intellectual activities as well as in every study and effort. Creativity is assumed to be a process at the end of which an original product is created. It also includes flexibility, multi-sided thinking, sensitivity, interest in human beings and rationalism. This study was carried out to evaluate secondary school directors’ views about their organisational creativity and managerial efficiencies. The aim of this research is to investigate school directors’ efficiencies in organisational creativity and management through the specified sub-problems and determine the connection between managerial efficiency and organisational creativity. The research was carried out through the qualitative method, which is based on an interdisciplinary holistic view in interpreting the research question. The facts and events are interpreted in terms of people’s understanding. Semi-structured interview questions were used to increase the reliability of the study. Face-to-face interviews were conducted with 18 secondary school directors and assistant directors in a qualitative method. The data were recorded on the computer and then analysed through content analysis, one of the qualitative research techniques. The main aim of content analysis is to reach concepts and connections to help the explanation of the data. Questions written in advance were subjected to content analysis so as to open a way to redo the study. The findings in this research revealed that the directors who supported common decision-making and collaboration exhibited sufficient managerial efficiency. Physical and infrastructure shortages in secondary education cause inequality in education. The most crucial factors in achieving school targets need to be constantly trained in technological, humanitarian and conceptual dimension skills of management science before and after undertaking their positions.

Published: December 2020

The higher education in Latvia became remote in the spring of 2020 due to the pandemic of Covid-19. Bearing in mind the probability of reoccurrence of a similar crisis, the aim of the study is to establish the self-evaluation of digital communication and collaboration skills of Latvian higher education students, and to detect the difficulties experienced during the remote study process. Data was collected through an online survey. Study shows that although the self-assessed level of competence of digital communication and collaboration skills is high, the use of skills is not as frequent, indicating that remote study process is not equivalent to on-site education. The academic staff is advised to vary teaching methods to stimulate use of different skills.

The process of developing education is a vital and important issue around the world as it is an issue that is inherited through time, and it is one of the most important challenges facing the world. Distance education is one of the means of developing education through which knowledge can be spread and which can help people to overcome obstacles of time and space. Recently, teaching and learning systems have become completely dependent on e-learning, especially during the corona virus disease (COVID-19) pandemic since the world has turned to electronic transactions in all areas, especially in education, and the most used technology includes the use of online training courses such as massive open online courses (MOOCs). It provides great support to the distance learning process as it can facilitate the learning process by diversifying its contents via media, such as text and video. In addition, MOOCs are the most popular and effective online courses. The aim of this paper is to provide an in-depth analysis of the definition, characteristics and patterns of MOOCs. Also, this paper discusses the specific advantages and disadvantages of taking up MOOCs along with the different challenges that MOOCs are facing. In addition, various suggestions will be given to make improvements that can help in making process enhancements to MOOCs. Finally, this paper presents the importance of MOOCs in the COVID-19 era. We hope this paper will help instructors to understand how MOOCs can be made more efficient, enable learners to become more organised and increase their understanding of MOOCs, and will help education development system specialists to find suitable solutions for problems that MOOCs are facing.

El Perú presenta diversas eventualidades como las lluvias, que retrasan distintas actividades que promueven el crecimiento económico del país. Las zonas urbanas necesitan una mejora continua del entorno con mejores infraestructuras para promover el crecimiento y reducir los accidentes. En la actualidad, se necesita fomentar por el medio local soluciones innovadoras para la evacuación de altas precipitaciones. El concreto permeable es un tipo de concreto cuya tecnología permite que el agua discurra a través de su estructura por la alta porosidad que posee a diferencia del concreto tradicional. Es fabricado de agregado grueso y material cementante, con un bajo porcentaje de finos de hasta el 10%. Esta investigación consiste en proponer un diseño de mezcla de concreto permeable de f’c=175kg/cm² aplicado en veredas que satisfaga distintos requerimientos establecidos por las normas CE010 de Pavimentos Urbanos, ACI 211.3R, ACI 522R-10 y los propios de la zona de aplicación. Para ello se realizó una batería de 12 diseños de mezcla con relaciones a/c 0.30, 0.35 y 0.38; agregados de HUSO 7 y 67; cementos portland tipo 1 Sol y Quisqueya; y aditivo Z fluidizante SR. Se realizaron ensayos en estado fresco: Slump, peso volumétrico y contenido de vacíos; y en estado endurecido: Resistencia a la compresión y flexión, y permeabilidad. Finalmente se realizó un prototipo con el diseño que presentó mejores características con el propósito de validar la investigación y se realizo un comparativo entre las veredas de concreto permeable y tradicional.

Esta intersección presenta congestionamiento vehicular ocasionando pérdida de horas hombre. Debido a esto, se determinó los niveles de servicio actuales, a través del software Synchro 8.0, mediante aforos vehiculares tomados en campo. Los niveles de servicio obtenidos fueron muy bajos y demoras elevadas. Como consecuencia se plantearon y modelaron con el software Synchro 8.0 diferentes propuestas para solucionar la congestión vehicular, tales como; Implementación de cruceros semafóricos con diferentes diseños, implementación de mini óvalos dentro de la intersección y en los extremos de la intersección, y un intercambio vial de tipo Diamante Divergente. La propuesta de solución se inicia con la comparación de resultados obtenidos de las alternativas para el escenario actual y proyectado a 5 y 10 años. En consecuencia, se obtuvieron dos propuestas que solucionan la congestión vehicular actual y proyectada a 5 años. La primera es la implementación de cruceros semafórico con un carril exclusivo para el giro libre a la derecha y la segunda es la implementación de un novedoso intercambio vial de tipo Diamante Divergente, mientras que las demás propuestas no son sostenibles en la proyección del tránsito futuro. Por otro lado, si bien es cierto que ambas propuestas mejoran y dan solución al problema planteado la segunda presenta mejores niveles de servicio y menores demoras en la proyección a 10 años.

INTERACTIVE METADISCOURSE MARKERS IN EFL MAJORS’ SUMMARIES IN ENGLISH
Authors: Radić-Bojanić Biljana B.
Published: December 2020

EFL majors’ academic training includes the development of academic skills, primarily academic reading and writing, which are important since English majors have to read many books and papers during their studies and often have to write papers on the basis of what they have read. This implies the students’ ability to decide which parts of the text are important and will be mentioned in the paper they are writing, as well as the ability to synthesize the material in a reader-friendly manner in accordance with the Anglophone academic tradition, which heavily relies on the use of metadiscourse markers that guide the reader through the text. In order to investigate to what extent EFL majors use interactive metadiscourse markers (Hyland 2005, 2010), which concern the writer’s awareness of a participating audience and address ways of organizing discourse, a research study was conducted with 59 English majors in their fifth year (MA level), who read a paper published in an academic journal and were asked to write a 250-word summary. The material was analyzed with the AntConc freeware and the results are used as a basis for pedagogical recommendations that aim at improving students’ training in academic writing.
THE USE OF METADISCOURSE MARKERS IN ESSAYS WRITTEN BY ESP UNIVERSITY STUDENTS
Authors: Vesić Pavlović Tijana , Đorđević Danijela
Published: December 2020

The study deals with metadiscourse markers employed in the essays written by ESP university students of mechanical engineering. The aim was to investigate the frequency of use of metadiscourse markers and to determine their types according to Hyland’s (2005) taxonomy. The corpus consisted of 100 essays dealing with two topics related to mechanical engineering. The research findings indicate that students used interactional metadiscourse categories to a significantly higher extent than interactive metadiscourse categories. The most used markers overall were transitions, followed by engagement markers and hedges. This suggests that students tried to capture the attention of their readers and make them participate in the discussion. Still, some markers were misused or overused, which implies that students need more instruction in the adequate use of markers. It can be concluded that adding explicit instruction in the use of metadiscourse markers to the ESP university curriculum would increase the level of students’ pragmatic competence so as to help them avoid pragmatic failures in writing.
HOW UNIVERSITY TEACHERS OF ENGLISH FOR SPECIFIC PURPOSES AND THEIR STUDENTS EMPLOY DICTIONARIES IN TEACHING AND LEARNING
Authors: Glušac Tatjana , Milić Mira
Published: December 2020

This paper explores how tertiary level teachers of English for Specific Purposes (ESP) and their students use dictionaries in ESP teaching and learning. The study included 21 ESP teachers and 705 students from the University of Novi Sad. Data were gathered by conducting a questionnaire (one for teachers and one for students) and an interview. The teachers’ questionnaire had 45 questions, whereas the students' contained 60 questions. Of these, 16 questions were identical and the answers to them were compared using ANOVA. The results reveal that the teachers’ and students’ views of dictionary use differ significantly with respect to 11 questions. The students primarily use online bilingual dictionaries and tools, whereas the teachers prefer monolingual dictionaries in the form of mobile phone applications. Dictionaries were primarily used for finding word meanings, with students failing to understand all lexicographic information. The results necessitate that both students and teachers receive training in dictionary use and that dictionaries become an obligatory teaching and learning resource.
NEOLIBERALNI PROSTORI U FILMU MOJA PRELEPA PERIONICA I U ROMANU BUDA IZ PREDGRAĐA HANIFA KUREJŠIJA
Authors: Milosavljevic Tatjana
Published: December 2020

Književna i filmska produkcija britanskih autora kolonijalnog porekla poseduje izraženu političku komponentu koja gotovo jednoobrazno ispituje svojim estetskim i narativnim formama različite aspekte neoliberalne hegemonije. Prikazi hijerarhijski podeljenih urbanih prostora su jedna od strategija kojima ovi tekstovi dovode u pitanje diskurs da je savremena neoliberalna Britanija post-klasno i post-rasno društvo. Dramski, književni i filmski rad Hanifa Kurejšija (Hanif Kureishi) nezamenjivi je vodič kroz britanski neoliberalni pejzaž. Rasna i klasna topografija Londona u eri tačerizma ogleda se u oba dela kojima se ovaj rad bavi – Kurejšijevim romanom Buda iz predgrađa (The Buddha of Suburbia, 1990) i filmom za koji je napisao scenario Moja prelepa perionica (My Beautiful Laundrette, 1985). Ova dela protivreče tačerovskoj viziji o Britaniji osamdesetih kao homogenoj naciji, govoreći o pluralnostima i dubokim procepima subjektiviteta. Cilj ovog rada je da, na tragu savremenih teoretičara ideologije u poznom kapitalizmu, prikaže da je Kurejšijeva ambivalentnost prema neoliberalizmu produkt tekstualne svesti o tome da se ovde radi o poretku sposobnom za aproprijaciju intimnih prostora i njihovu transpoziciju u prostore gde društveni subjekti ostvaruju materijalne uslove za život. Zaključak je da pozni kapitalizam briše granicu između privatnog i poslovnog prostora, neutrališući tako svest subjekta o predideološkoj realnosti, utoliko koliko je ona zamisliva.

Authors: Feng Yuye , Wu Qingbiao
Published: December 2020

This paper proposes the modified generalization of the HSS (MGHSS) to solve a large and sparse CS equation, improving the efficiency and robustness. The analysis shows that the MGHSS converges to the unique solution of AX+XB=C unconditionally. We also propose an inexact variant of the MGHSS (IMGHSS) and show its convergence property. Numerical experiments verify the efficiency of the proposed methods.

Dehydrodiisoeugenol (DEH), a novel lignan component extracted from the Nutmeg seeds, displays noticeable anti-inflammatory and anti-allergic effects in digestive system diseases. However, the mechanism of its anti-cancer activity in gastrointestinal cancer is still to be investigated. Here, the anti-cancer effect of DEH to human colorectal cancer and its underlying mechanism were evaluated. The DEH treatment arrests the cell cycle of colorectal cancer cells at G1/S phase, which leading to a significant cell growth inhibition. Moreover, it can induce strong cellular autophagy and the autophagy would be inhibited through autophagic inhibitors with reducing EDH-induced inhibition of cell growth in colorectal cancer cells. Further studies indicated that DEH can also induce endoplasmic reticulum (ER) stress, and could subsequently stimulating autophagy through activating PERK/eIF2α and IRE1α/XBP-1s/CHOP pathways. Knockdown of PERK or IRE1α can significantly decrease the DEH-induced autophagy and retrieve cell viability in cells treated with DEH. What’s more, DEH exhibits significant anti-cancer activities through CDX- and PDX-model as well. Taken together, our studies strongly suggest that DEH might be a potential anti-cancer agent against colorectal cancer via activating ER stress-induced autophagy inhibition.

Model of a Photovoltaic Module for the MatLab/Simulink SimPowerSystems Library
Authors: Zalizny D. I.
Published: December 2020

The relevance of research is caused by the increase of the number of photovoltaic power plants in the Republic of Belarus and, accordingly, the need to solve problems of diagnostics of photovoltaic modules. A new Simulink model of a photovoltaic module focused on using the standard SimPowerSystems library of power supply system elements (a part of the MatLab/Simulink) is proposed. The model allows altering solar irradiation values for each solar cell of the module. The use of the model also makes it possible to obtain calculated values of voltages and currents at the photovoltic module output. In addition, the model provides the simulation of individual solar cells shading in the module. The developed Simulink model operates on the base of a well-known exponential dependence describing the volt-ampere characteristic of a photovoltaic module, and also takes into account the real circuit of the module with bypass diodes. The series resistance of the photovoltaic module is calculated by the subtraction between its experimental and theoretical volt-ampere characteristics for conditions that are close to normal. The Simulink model of the SF-P672300 module contains 72 nonlinear elements implemented on the basis of controlled current sources and connected in series. The model solved the problems of the algorithm stability for calculating algebraic cycles by introducing constraint the current and the voltage parameters. Experimental studies for the fully illuminated and partially shaded SF-P672300 module have demonstrated that the maximum relative error of the developed Simulink model does not exceed 15 %. Experimental and theoretical current-voltage characteristics of the SF-P672300 module under full illumination and partial shading are presented. The presented Simulink model may be used both at the design stage and at the operation stage of photovoltaic power plants in order to simulate and analyze the factors that affect the operation of them.
Challenges in enabling aging-in-place initiatives in aging and shrinking Japanese cities: a case of the Gifu suburbs

This study first reviewed previous literature on 1) the residential environments and everyday lives of older adults to examine universal factors enabling aging-in-place initiatives, and 2) the generation and outcomes of aging and shrinking suburbs in the Japanese context, via comparisons with case studies in Western cities. A case study was then conducted in the suburbs of Gifu to provide a clear impression of older adults’ daily lives and their perceived barriers in aging and shrinking suburbs in Japan. Finally, we discussed challenges involved in enabling aging-in-place initiatives whose major goal is to provide residential environments in which older adults can maintain continuous residency in their attached homes and neighborhoods in Japanese cities. The case study revealed that many older adults wished to continue living in their homes and neighborhoods. Diversification of accessible support in families and modification of interrelationships among family, housing, and welfare can contribute to adjustments in later life. Systems to support mobility after ceasing driving should be examined in more detail, because older adults were not satisfied with bus service quality, resulting in individuals postponing the decision to cease driving. To enable aging-in-place initiatives in Japan, cooperation among different ministries in national government and divisions at the municipal level is necessary.

Staphylococcus aureus (S. aureus) is a leading cause of hospital and community acquired infections globally. Methicillin-resistant Staphylococcus aureus (MRSA) prevalence has been reported to be high in various settings and is associated with increased morbidity, mortality and risk of nosocomial outbreaks. Surveillance of prevalence and antibiotic susceptibility patterns is important to ensure appropriate antibiotic prescription. The objective of our study was to establish the prevalence of S. aureus, to identify patterns of susceptibility to commonly used antibiotics and quantify contemporary penicillin resistance among S. aureus. A retrospective study was conducted at the Mater Misericordiae Hospital, Nairobi. The study involved a review of non-duplicate records of specimens analyzed between January 2014 and December 2018.A specimen was categorized as Penicillin susceptible (PSSA) if susceptible to Penicillin and Oxacillin, MSSA if resistant to Penicillin but susceptible to Oxacillin, and MRSA if resistant to Oxacillin. We present proportions of S. aureus that was PSSA, MSSA and MRSA. Multivariate logistic regression was used to determine the association between the presence of S. aureus isolates and the source of the clinical specimen (in vs. outpatient), age and gender. A total of 659 specimens of S. aureus were analyzed in the 5-year period. ​​PSSA was the most prevalent organism seen (60.85%) while MRSA was the least prevalent (0.61 %). Most S. aureus was isolated in pus from wound swabs-644 (73. 3%). A significant increase in susceptibility of S. aureus to Penicillin and Amoxicillin-clavulanic acid was observed during the study period however, sensitivity to Amoxicillin declined. This study demonstrated a high prevalence of Penicillin Sensitive S. aureus and a low prevalence of MRSA.

Due to the lack of primary amino groups, lipids cannot be fixed by formaldehyde, glutaraldehyde and other chemical fixatives nor expanded using expansion microscopy (ExM). We present a protocol that uses unnatural short-chain azide- and amino-functionalized ceramides, which upon incorporation into cellular and bacterial membranes can be labeled by click chemistry and linked into hydrogels, followed by 4x to 10x expansion.
