Organizations are facing challenges to cope with gender equity in the presence of a diverse workforce. The present study investigates the moderating impact of Islamic work ethics on the organizational justice-gender equity relationship. Self-administered questionnaires were sent to employees working in a large private university in a State of Qatar. This study collected data from 250 employees with 66.12% response rate. The present study employed structural equation modelling to analyse data in SmartPLS 3.0 and SPSS version 24. Empirical findings revealed the significant relationship of distributive justice and interactional justice with gender equity. Procedural justice did not relate to gender equity. Furthermore, Islamic work ethics also moderated the relationship of interactional justice with gender equity. Limitations and implications have been added at the end of paper. This study is first in its nature revealing the conditional factor of Islamic work ethics on the organizational justice-gender equity relationship.
Macroeconomic Instabilities and Cost-Recovery Potentials of Public Sector Organisations
Authors: Sanga Samwel Alananga
Published: April 2021

The 2008 financial crisis aroused concerns over the performance of public sector organisations operating under different cost recovery regimes.  These concerns were linked to potential failure in attaining cost recovery targets as a result of declining revenues during economic downturn.  Using LME models on data from the World Bank website and from six Land Administration Organisations (LAOs), it is established that a global financial crisis that is associated with declining GDP and higher inflation rate can insignificantly reduce the level of cost recovery for LAOs while persistent decline in GDP growth rate significantly eliminate potentials for cost recovery.  However prospects for recovery can be traced within the cost-revenue microstructures of LAOs themselves.  With a significantly negative relationship between spending in information and technology as a ratio of GDP to the degree of cost recovery, LAOs need only to eliminate rigidities in their cost-revenue structure which tie them to macro-instabilities of the real estate market.  Such flexibility can be attained through elastic cross-substitution in the LAO’s gross cost-revenues schedules for registration tasks in favour of information delivery tasks.

Authors: Dahal Kedar , Timilsina Krishna P.
Published: April 2021

The rapid transformation of rural settlements into municipalities in Nepal has brought significant changes in land use, and urban expansion and growth patterns mostly through the conversion of agricultural land into the built-up area. The issue is studied taking a case of the rapidly growing town, Barahathawa Municipality of Tarai Region of Sarlahi District. After the declaration of the municipality, several new roads have been opened and upgraded; and the municipality is well-connected to the national transportation network. After promulgated the Constitution of Nepal 2015 and functioning the elected local body, the municipality budget has been increased significantly as a result of increasing municipal investment in socio-economic and physical infrastructure development and environmental protection which has attracted people, goods, and services creating the zone of influence on the municipality. One of the changes found in the municipality is the increasing built-up area and expansion of urban growth through the decreasing agricultural land. Urban growth has been observed taking place around the Barahathawa Bazaar and main roadsides. The built-up area in Barahathawa municipality has remarkably increased by 183percent with the decrease of shrub and agricultural land within 10 years. Implications of such spatial and temporal dynamics have been a core issue of urban planning in most of the newly declared municipalities in Nepal.

Stable and adaptive superior varieties play an important role in increasing plant productivity. The technological innovation was carried out by studying the yield GEI. However, if only paying attention to yield GEI would not be enough in selecting stable and adaptive varieties, so this research used a combination of AMMI and SEM methods. Through the SEM-AMMI, GEI modeling was carried out by taking into account the physiological processes of growth and genotype development which explained the relationship between yield GEI components and how it affected yield GEI. The results of the AMMI biplot showed that genotypes were adaptable and relatively stable were planted in five planting locations, namely Biru Lancor and Tinombo. SEM test results showed that the yield component has an effect on production yield, where the tuber weight above the average will give relatively more onion yields and genotypes planted in relatively low locations, soil pH above 6 and dusty clay soil conditions will produce relatively more red onions and quality.

This research discusses language maintenance and language shift among children from intermarriage family. It could be found in a society that many children who grow up from intermarriage family have bilingual and multilingual. But in some cases, this condition also become the factors that cause them losing their cultural identity due to their parents do not introduce and teach them their mother tongue language. This condition will be affected the existence of those local languages because it could make them appear or even the worst thing that it could make them become death. Those effects have been found in many local languages in Indonesia in which many local languages have extinct and some of them are going to be extinct. The aims of this research are to describe the phenomenon that appears within the students of English Language and Literature Adab and Humanities Faculty UIN STS Jambi who have intermarriages family’s background. Besides that, it also aims to find out the role of parents to decide the language choice used by their children. Since this research lay down from the previous researchers that find out parents are the important role in deciding language choice for their children. Observation and questionnaire are the techniques used in collecting the data. The results show that parents have a role that causes the shift and the maintenance of local languages. In addition, the factors such as bilingual, language’s choosing and using at home and migration are the causes of language shift found in English Language and Literature students. But the researcher found that code switching and code mixing are only used by the students for a specific situation where they should elaborate their language with their listeners.

Tässä artikkelissa tarkastelen metamodernia utooppisuutta kahdessa vuonna 2016 ilmestyneessä romaanissa, Emma Puikkosen Eurooppalaisissa unissa ja Riikka Pulkkisen Parhaassa mahdollisessa maailmassa, joita yhdistävät samankaltaiset muotoratkaisut ja Euroopan lähihistorian käsittely. Pyrin osoittamaan, kuinka romaanit koettavat ylittää postmodernin ironisen eetoksen ja kuinka aikamme utopianvastaisuus ja toisaalta tarve utooppiselle ajattelulle tematisoituvat romaanien tavassa käsitellä eurooppalaista lähihistoriaa.
Endocrine Obitopathy: a Personalized Approach to Patient Сare
Authors: Petrenko O. , Prusak O.
Published: April 2021

Background. This article highlights the main approaches to the treatment of patients with endocrine orbitopathy (EO) and current opportunities for planning and conducting personalized orbital decompression, including the use of Computer-Aided Design (CAD) / Computer-Aided Manufacturing (CAM) technologies. Optimization of treatment of this pathology which can lead to changes in appearance, inability to perform usual work, social isolation, and in the most difficult cases to vision loss is a topical issue of ophthalmology and maxillofacial surgery. The aim. To analyze current information on basic approaches to the treatment of patients with endocrine orbitopathy and the possibility of using computer technologies for planning and performing personalized orbital decompression. Results. The use of corticosteroids, radiation therapy, surgical treatment are the key methods used to manage patients with EO. The use of CAD/CAM technologies allows to plan surgery according to the morphological features of the orbit of each patient. This can potentially affect the outcome of decompression and reduction of exophthalmos, as well as intraoperative complications. When using standard approaches, the results of decompression may vary significantly due to the differences in morphological parameters of the orbits. This dictates the need for a personalized approach to the management of patients with EO. Due to the significant variability of morphological parameters of the orbits in the case of standard approaches, the results in different patients can differ significantly, which dictates the need for a personalized approach to the management of patients with EA. Conclusions. EUGOGO 2016 recommends a multidisciplinary step-by-step approach to the management of patients with EO, depending on its activity and severity and the impact on the patient’s quality of life. A personalized approach using computer simulations and the development of surgical navigation templates for surgical decompression of the orbit will ensure optimal functional and aesthetic treatment results. Keywords: endocrine orbitopathy, treatment, orbital decompression, ComputerAided Design (CAD) / Computer-Aided Manufacturing (CAM) technologies, personalized approach.
Lactoferrin: Invisible Eye Defender
Authors: Drozhzhyna G. I. , Veliksar T. A.
Published: April 2021

The main protective proteins that are synthesized by eye cells are lactoferrin (Lf), lysozyme, immunoglobulin-A, and tear lipocalins. It has been proven that Lf is contained in biological ﬂuids and mucous membranes of various organs; this highlights the importance of this protein in the first line of defense from pathogenic microorganisms. Lf is a non-heme iron-binding chelating glycoprotein from the transferrin family. Lf carries out bactericidal, fungicidal, antiviral, antioxidant and transport functions, prevents the formation of free radicals, inhibits lipid peroxidation, activates enzymes of the antioxidant system. Lf is contained in tears in the highest concentration (about 2 mg/ml, 25% of tear proteins), the average concentration is 1.42 mg/ml. Lf is an important component providing homeostasis of the ocular surface, modulates the activity of T-lymphocytes and macrophages in infections, prevents the multiplication of pathogenic microﬂora, the development of inﬂammation, protects the integrity of the cornea, promotes healing from microtraumas, controls the level of iron in the lacrimal ﬂuid, and protects against toxins. These properties of Lf open up prospects for its application in the treatment of chronic diseases of the ocular surface and, in particular, dry eye disease. Lf concentration in tears decreases during sleep, with age, in dry eye disease, keratitis and conjunctivitis, when using contact lenses, that increase the risk of developing eye infections. The first results of the application of ophthalmic drops Lacto (NOVAX® PHARMA) showed good tolerance and therapeutic efficacy in the treatment of inﬂammatory diseases of the ocular surface. Keywords: lactoferrin, tear, antimicrobial, immunomodulatory, anti-inﬂammatory properties, ocular surface.

Strategies of the International Agency for Research on Cancer (IARC/WHO) to reduce the occupational cancer burden
Authors: Olsson Ann , Schubauer-Berigan Mary , Schüz Joachim
Published: April 2021

The main mission of the International Agency for Research on Cancer (IARC/WHO) is to conduct research for cancer prevention worldwide. The strategies of the IARC to reduce the occupational cancer burden include enhancing cancer surveillance, evaluating and classifying potential human carcinogens, and conducting epidemiological research to fill gaps in knowledge on occupationally related cancers. Beyond the IARC work, it is essential to systematically monitor occupational exposures in workplaces, in order to effectively protect workers. There are multiple sources of information about occupational exposures in workplaces, but they are often not used for hazard surveillance or for research. The Russian Federation has great potential to advance research and worker protection due to their strong tradition to monitor and record exposure concentrations in workplaces. Currently most evidence regarding occupational cancer burden comes from Western Europe and North America. Estimation of the burden of occupational cancer requires accurate data from local settings as extrapolating data from other settings may be misleading due to major differences in exposures, exposure pathways and baseline cancer risks. To fill this knowledge gap, it is important to conduct exposure surveillance and epidemiological studies on occupational cancer in the Russian Federation.

Published: April 2021

Introduction. There are data on the effects of dust on the respiratory system and the cardiovascular system. The main measures for preventing diseases of the circulatory system aimed to identify and eliminate risk factors. However, the prevalence of risk factors for coronary heart disease among coal mine workers with anthracosilicosis has not been sufficiently studied, determining the study's relevance. The study aimed to learn the frequency of risk factors for coronary heart disease in coal industry workers with anthracosilicosis. Materials and methods. We examined 269 miners working in conditions of dustiness exceeding the maximum permissible concentration by ten or more times: 139 miners with a previously established diagnosis of anthracosilicosis and 130 miners of the control group without dust pathology of the lungs. All of them underwent a comprehensive clinical, instrumental, and laboratory examination of the respiratory and cardiovascular systems to detect anthracosilicosis and coronary heart disease, as well as to assess its risk factors. Results. In miners with anthracosilicosis, coronary heart disease was 3.5 times more common (30.94%) than in the control group (8.46%). We have identified a high incidence of coronary heart disease in the age group of 45 and more years and with the experience of working in dust conditions of 20 and more years. In miners with anthracosilicosis combined with coronary heart disease, arterial hypertension was 1.6 times more common (58.14%) than without concomitant coronary heart disease - 35.42%. Miners with a combination of anthracosilicosis and coronary heart disease were three times more likely (20.93%) than those without coronary heart disease (6.25%) to have a metabolic syndrome. According to the Tanner index, significant risk factors for coronary heart disease were the presence of an andromorphic constitutional-morphological type and the formation of a complication of anthracosilicosis - respiratory failure. The evaluation of biochemical blood tests showed that the most significant markers of coronary heart disease risk were hyperhomocysteinemia, increased levels of C-reactive protein, fibrinogen, and soluble fibrin-monomer complexes. Conclusions. We found that the most significant risk of developing coronary heart disease in miners is 45 years and older. There are also other risk factors: work experience in harmful working conditions of 20 years or more; the presence of arterial hypertension; metabolic syndrome; andromorphic constitutional-morphological type according to the Tanner index. Risk factors are respiratory failure, hyperhomocysteinemia, hyperfibrinogenemia, increased soluble fibrin-monomer complexes, and C - reactive protein. It is necessary to consider all risks in developing programs of medical and preventive measures for employees of the coal industry.

Published: April 2021

Introduction. The systemic violation of the body's homeostasis under the conditions of the negative impact of production factors scientists determine by the mismatch of neurohumoral mechanisms of regulation of metabolic processes. There are endocrinopathies. They occur with disorganization of the metabolism and violation of the thyroid gland's functional activity with disorganization of the metabolism, infringement of the thyroid gland's available action. The study aimed to learn the nature of endocrine dysfunction, histological changes of the thyroid gland associated with the dynamics of chronic fluoride intoxication of the body. Materials and methods. We analyzed the state of bone tissue and assessed the degree of articular syndrome during the large-scale structural reconstruction of the skeleton in aluminum production workers. The scientists examined the workers using double photon densitometry. The researchers studied the metabolic parameters based on a range of biochemical and instrumental methods. The experiment involved sexually mature male white laboratory rats with a bodyweight of up to 300 grams. We analyzed hormonal status disorders with an assessment of the degree of morphological changes in the thyroid gland. Results. The researchers analyzed the severity of disorders of individual endocrine mechanisms of homeostasis regulation and thyroid morph structure in hyperfluorosis. We treat fluorosis as a polyfunctional pathology. A high proportion of endocrinopathies is a clinical syndrome. It increases the pathological course of chronic fluoride intoxication in workers. We confirm the study with experimental data on metabolic disorders with a persistent toxic effect. We revealed hyperfunction of the thyroid gland against the background of a decrease in glucocorticoid activity, stable electrolyte, and mineral shifts. The researchers conducted an experiment on the late stages of fluoride intoxication. Conclusions. Clinical studies of individuals with chronic fluoride intoxication and concomitant endocrinopathy revealed a significant increase in the number of workers with abdominal obesity, musculoskeletal disorders, mineral metabolism disorders. Also, with deforming osteoarthritis of the joints, osteoalgia against the background of thyroid insufficiency. Experimental data confirm this. The fluorine accumulation in the body causes multidirectional disorders of the hormonal mechanisms of regulation of metabolic processes, alternation of hypo- and hyperfunction changes in the thyroid gland associated with fluoride duration intoxication.

Published: April 2021

Introduction. The fundamental mechanisms of the body's pathological reaction to coal and dust exposure are hypoxia, excessive activation of free radical processes, structural and metabolic disorders in various organs. Organ-specific molecular defense mechanisms begin to function in the form of changes in the level of proteins with antihypoxic (HIF-3a), chaperone (HSP72), and antioxidant functions (HOx-1 - heme-oxygenase, Prx-1 - peroxiredoxin) under damaging effects. Its high level contributes to the restoration of cells' functional state or indicates significant damage in tissues. Hypoxia and free radical processes are known to lead to severe brain damage and behavioral disorders. To date, little is known about the expression of protective proteins and morphological changes in the brain under prolonged exposure to coal-rock dust on the body. The study aimed to learn the level of intracellular protective proteins HIF-3a, HSP72, HOx-1, Prx-1, and morphological changes in the brain in the dynamics of long-term dust exposure. Materials and methods. Sixty white male Wistar rats weighing 200-250 g of the same age took part in the experiment. Dust exposure was modeled by way of dynamic inhalation priming of rats with coal-rock dust (coal of a gas-fat brand) in an intermittent mode for 12 weeks. We perform morphological studies of the brain after 1, 3, 6, 9, and 12 weeks of dust exposure. The cytosolic fraction of brain tissue researchers determined the expression level of HIF-3a, HSP72, HOx-1, and Prx-1 by Western blot analysis. We selected the activity of free radical processes in the brain tissue. Results. Long-term exposure to coal-rock dust on the body at the morphological level in the brain revealed changes that indicate the development of hypoxia and activation of free radical processes: microvascular disorders, pericellular edema, severe dystrophic damage to neurons, focal loss of neurons, activation of glial cells. Activation of the protective proteins HIF-3a, HSP72, HOx-1, and Prx-1 in the early stages (1-3 weeks) of coal-dust exposure provided compensation for free radical processes in brain neurons. An increase in the duration of dust exposure of more than six weeks influences a low level of HSP72, but high HIF-3a and Prx-1, indicating an increase in hypoxic and free radical damage brain. Conclusions. The results obtained to expand the understanding of the morphological and molecular mechanisms that occur in the brain tissue during prolonged dust exposure to the body are essential for developing methods for organ-specific pharmacological correction.

Published: April 2021

Introduction. In the modern world, the introduction of digital technologies in healthcare is one of the priorities of development, which opens up a wide range of opportunities from screening and monitoring to various health disorders. In 2020 we completed the work to evaluate the applied capabilities of contactless videoplethysmography based on the telemetric control system developed by us and patented using the DISITA software and hardware complex during pre-trip post-trip medical examinations in 19 drivers of passenger vehicles. The study aims to explore the possibilities of the data of variational heart rate monitoring using reflected video plethysmography in assessing drivers' performance in their work. We have identified the most sensitive and significant heart rate variability indicators that reflect the professional load's impact. Materials and methods. We carried out during the usual pre-trip examination, video plethysmography of the skin of the face of the subjects in parallel in conditions of both natural daylight and typical artificial lighting of medical and diagnostic rooms, at a distance of the recording WEB camera of the DISITA software and hardware complex from the face of the subject within 40-70 cm. Researchers examined the methodological recommendations developed by the Izmerov Research Institute of Occupational Health team and RT-Medicine JSC. Results. We use videoplethysmography to evaluate variational heart rate monitoring as a method for assessing functional states during mass pre-trip (pre-shift) and post-trip (post-shift) medical examinations. In this case, the heart rate estimated by palpation was identical to the heart rate obtained by videoplethysmography. The most sensitive parameters characterizing the impact of professional load on drivers were changes in the indicators of variational heart rate monitoring: SDNN, RMSSD, CV, TR, HF, LF, and the waves of vasomotion regulation. Conclusions. Videoplethysmography with an assessment of the data of variational heart rate monitoring can be used to predict the functional state (stability of the body) of drivers in the course of their professional activities.

Published: April 2021

Introduction. Heart rhythm disorders in locomotive drivers are a significant disease that increases the risk of sudden death and thromboembolic complications, including during professional duties. Conditions associated with cardiac arrhythmias in locomotive drivers can create a state for disastrous situations on the railway. Identification of risk factors for heart rhythm disorders and their prevention in locomotive drivers is an important task. The study aimed to study the role of vitamin D in developing cardiac arrhythmias in locomotive drivers. Materials and methods. We recruited the patients in the cardiology department's conditions, JSC "Russian Railways" in Moscow. The study included patients with detected cardiac arrhythmias. We did not have patients with a history of surgical treatment of cardiac arrhythmias with organic myocardial diseases. Namely: ischemic heart disease, myocarditis, congenital and acquired heart defects, cardiomyopathy. Also, scientists did not study patients with somatic disorders, decompensation of chronic diseases, and endocrine and urinary systems. Results. The study revealed a widespread prevalence of low vitamin D levels among locomotive drivers with cardiac arrhythmias. The statistical analysis showed the effect of vitamin D deficiency on cardiac arrhythmias' development with a high risk of sudden death and thromboembolic complications. We revealed the negative impact of occupational stress on the development of cardiac arrhythmias in locomotive drivers. Scientists have found the relationship of vitamin D deficiency with the level of anxiety of drivers. A review of studies on the role of vitamin D deficiency in developing cardiovascular diseases, including cardiac arrhythmias, is presented. The results of the study are consistent with the data of the scientific literature. Conclusions. It is necessary to survey locomotive drivers to identify vitamin D deficiency with the subsequent correction to prevent cardiac arrhythmias.

Fog Integrated Secured and Distributed Environment for Healthcare Industry with Software Defined Networking
Authors: Kh-madhloom Jamal
Published: April 2021

Fog computing is a segment of cloud computing where a vast number of peripheral equipment links to the internet. The term "fog" indicates the edges of a cloud in which high performance can be achieved. Many of these devices will generate voluminous raw data as from sensors, and rather than forward all this data to cloud-based servers to be processed, the idea behind fog computing is to do as much processing as possible using computing units co-located with the data-generating devices, so that processed rather than raw data is forwarded, and bandwidth requirements are reduced. A major advantage of processing locally is that data is more often used for the same computation machine which produced the data. Also, the latency between data production and data consumption was reduced. This example is not fully original, since specially programmed hardware has long been used for signal processing. The work presents the integration of software defined networking with the association of fog environment to have the cavernous implementation patterns in the health care industry with higher degree of accuracy.

This study presents an algorithm for the allocation of particulate phosphorus (PP) loads entering surface waters to their sources of origin, which is a basic requirement for the identification of critical PP source areas and in turn a cost-effective implementation of mitigation measures. Furthermore, it conducts a sensitivity analysis determining the impacts of storm drains, discharge frequencies and flow directions on the designation of critical source areas with the help of present-day scenarios for a case study catchment with an area of several hundred square kilometres. The results show that the scenarios at least partially disagree on the identified critical source areas and suggest that especially open furrows at field borders have the potential to cause deviating critical source areas. Finally yet importantly, the Particulate PhozzyLogic Index based on model results as well as fuzzy logic is introduced. Its main feature is to transform the results of diverse scenarios or even models into a final map showing a catchment-wide ranking of the possibility of high PP emissions reaching surface waters for all agricultural fields.
“If it is not made easy for me, I will just not bother”. Barriers and Facilitators to Recycling Plastics
Authors: Roy Debbie , Berry Emma , Dempster Martin
Published: April 2021

Millions of tonnes of plastic are ending up in our oceans and creating a global environmental hazard. Around 50 percent of plastics are designed for single use, mainly for food packaging. Plastic waste is often found discarded as litter, despite significant investment over the last 20-30 years to increase recycling facilities and kerbside collection of waste materials. While there is a substantive body of literature about general recycling behaviour, few insights exist that may help us understand why a sizeable number of consumers and householders are failing to sort plastics for recycling at optimal levels. As a consequence, used plastic is ending up in landfill and is polluting the environment. This current study used in-depth qualitative interviews within a framework that seeks to identify underlying opportunities, motivations and capabilities of individuals when it comes to plastic recycling. The principle findings are that the respondents are generally positive about recycling and express a degree of environmental concern about the damage plastic waste causes to the natural world. However, this concern does not translate into efforts to obtain accurate information about plastics disposal. Efforts are lower when visual reminders of its harmful impact are absent, and when faced with a confusing array of packaging that combines several types of plastics. Householders believe the responsibility for making plastic recycling easier rests heavily with local government and manufacturers. Until greater uniformity in packaging is achieved, plastics recycling rates may struggle to reach optimal levels.

Background: Central components of psychological functioning, such as difficulties in emotion regulation and interpersonal problems are likely to have been substantially impacted by COVID-19 and the amelioration measures of societal lock-down and social distancing. In turn, these factors are likely to predict mental health outcomes, such as symptoms of depression and anxiety throughout the pandemic and beyond. Methods: To investigate this issue, we conducted an internet-based survey with 10,061 responders at the height of lock-down (T1). After social distancing measures had been eased (T2), 4,936 responders (49.1%) completed the survey again. Results: Emotion regulation difficulties, interpersonal problems, and symptoms of depression and anxiety decreased from T1 to T2, but changes were minor. After controlling for age and gender, emotion regulation- and interpersonal difficulties were associated with anxiety and depression throughout the study period, and changes in all domains occurred in concert. More extensive problems with emotion regulation at T1 predicted greater reductions in both symptom domains as amelioration measures were eased, while the converse was true for interpersonal problems. Furthermore, the impact of initial emotion regulation difficulties on subsequent changes in both anxiety- and depressive symptoms was dependent on the level of interpersonal difficulties, so that high interpersonal problem load at T1 reversed the effect of emotion regulation difficulties on symptom development. Conclusions: The results suggest that emotion regulation- and interpersonal difficulties are highly central to mental health during the pandemic, and may be important targets for remediation to reduce mental health problems throughout the course of the pandemic and beyond.

This manuscript describes data collection, cleaning, and quality control procedures used in a large-scale, longitudinal, in-school study of executive function skills (EFs) and academic achievement in middle childhood, Project iLEAD (in-school Longitudinal Executive Function and Academic Achievement Database). Assessments were administered in real-world educational settings in a large sample of third through eighth grade students (ages 7 to 14; N = 1,280) over two years, with eight data collection timepoints in group settings. We assessed students with a novel, mobile EF assessment tool Adaptive Cognitive Evaluation (ACE). This battery included 11 tasks that were each designed to adapt to user performance in a trial-wise manner, allowing the same battery of tasks to be used multiple times within the same individual, and across a wide range of ages. Data quality analyses revealed that the adaptive algorithms were successful in equating challenge levels across ages 7 through 14 for 10 of 11 tasks. Data for each task were found to be approximately normally distributed and split-half reliability was acceptable across both accuracy and reaction time. ACE thus provides a reliable way to assess EFs in middle childhood using the same tasks while maintaining appropriate challenge level without facing ceiling or floor effects.
Proposed Model to Assist Saudi Postgraduate Students in their English Academic Writing
Authors: Alharbi Noof Saleh
Published: April 2021

This current research forms part of a broader investigation into the problems Saudi postgraduate students face in English academic writing. The study used the interpretive paradigm to investigate and interpret the perceptions of Saudi postgraduate students and their supervisors in relation to the difficulties they encountered regarding academic writing in English. Therefore, the study adopted a sequential mixed-methods design. The quantitative phase of the research employed a questionnaire whereas the qualitative phase employed semi-structured interviews and document analysis. In total, 275 students completed the prepared questionnaire whilst 15 students, both male and female, and 9 supervisors participated in the semi-structured interviews. The research also used ten samples of written feedback students had received from their supervisors. SPSS descriptive statistics were used to analyse the data quantitatively, and MAXQDA software was used to analyse the data qualitatively. The study identified that Saudi postgraduates encounter a range of difficulties in their academic writing, which were due to several underlying causes. Therefore, to address this issue and to contribute to knowledge in the field, the author of this study devised a theoretical model to assist Saudi postgraduate students overcome their difficulties with English academic writing. The main focus of the current study is to explain this model in detail.
Is Foreign Language Teaching Possible Without School? Distance Learning Experiences of Foreign Language Students at Ataturk University During the Covid-19 Pandemic
Authors: Bozavlı Ebubekir
Published: April 2021

Covid-19 pandemic forced Turkey, like other countries, to give up face to face teaching in all educational institutions and to move toward distance education. This research aims to determine the learning experiences of foreign language students participating in distance education during the pandemic and their beliefs about whether it is possible to learn a foreign language without school. There were two problems that attempted to be answered; first, is it possible to learn a foreign language during and after the pandemic without being physically at school and second, what kinds of experiences do students gain in distance learning of foreign languages. The sample of the study consists of the students of department of foreign languages at Atatürk University, in Turkey. The study was carried out with a sample population composed of two hundred forty-two male and female students from German, French, and English Language Education Departments. A questionnaire consisting of thirteen close-ended questions created with a 5-Likert type developed by the researcher was applied. Participants answered the questionnaire online via Atatürk University Course Information System. The data were analyzed through the SPSS program to determine their frequency and descriptive analysis, and interpreted with content analysis and descriptive analysis. The results demonstrated that students believe that they can’t learn a foreign language without going to school. Additionally, the findings indicated that their digital literacy skills are insufficient in distance teaching, and students show low motivation in learning
