Cognitive Aspects of Reception of Popular Literary Genres and Their Historical Variability
Authors: Zubov Artem A.
Published: July 2021

In the article, the author investigates connections between historical variability of literary genres and readers’ ability to recognize them. Following J.-M. Schaeffer, the author understands genre as a semiotic sign constituted of a “generic name” and “generic notion.” The author interprets Schaeffer’s theory from the perspective of cognitive poetics and treats genres as “prototypes.” Their nature is both individual and collective—it derives from a person’s individual experience and skills of aesthetic reception, but also from social imaginary and stereotypes. The author focuses on a noncanonical genre of popular literature—science fiction—and argues that social and receptive aspects of the genre are interconnected. In the final part, the author analyses the image of “generation starship” in science fiction and concludes that changes of poetic techniques used to create fictional space of science-fictional starships—which has no correlation with readers’ empirical surroundings—formed a new “reading paradigm”, i.e., addressed mechanisms of reception that were not relevant previously in the history of the genre.
Figurative-Compositional Ornamentality of Sudak Song in the Émigré Folklore of Crimean Tatars
Authors: Humeniuk Olha N.
Published: July 2021

Laconic songs, describing with the picturesque expressiveness and aphorismic clearness the sadness of parting with the motherland, became really wide-spread in the émigré folklore of Crimean Tatars. Compositional sophistication, emotional expressiveness are characteristic for these songs. They are notable for the touching lyricism, connected with the fact that exactly these songs are mainly about the parting with the loved ones: parents, friends, beloved girl. Fixed in several variants, Sudak tyurkyusi (Sudak Song) belongs to such folklore compositions. This song deals with the complicated dramatic relationships of two lovers who have to part. We can only guess what makes their relationships so complicated, but it is rather definitely mentioned that nobody could help the fatal influence of external factors. As well as difficult relationships of the lovers, bitterness and harm of adverse circumstances are clearly accented. The analyzed song has a certain lightness characteristic of the folklore style manner, even some playfulness, which effectively contrasts with the deep dramatic quality. The transfer of subtle, barely perceptible psychological nuances, emotional saturation are connected with the sophisticated oriental ornamentality, intensified by the eloquent, albeit unobtrusive, poetic parallelisms, as well as rhythmic and euphonic peculiarities of poetic description.
Blake Studies in the 21st Century
Authors: Serdechnaia Vera V.
Published: July 2021

The author summarizes Blake studies of the 21st century. The beginning of the modern era of Blake studies can be considered with the paradigm of deconstruction. At the end of the 20th century, synthetic analysis took a special place in Blake studies, when Blake’s illuminated books were studied as an inseparable unity of verbal and visual. Blake’s legacy has undergone a significant evolution related to deconstruction and postmodern approaches, and linguistic research. The development of traditional areas of research, such as psychoanalysis, textual criticism of manuscripts, religious and mystical allusions, and comparative studies is also traced. Postmodernism, which owes much to the Romanticism (i.e. the concept of irony, fragmentation, the category of the exalted, the original lonely hero), brought new features to Blake studies and greatly contributed to its approval among canonical authors of the Romanticism. In modern Blake studies, such areas as gender studies, postcolonial studies, studies in digital reality environments are most actively developing. Starting from the 2000s, the main direction in Blake studies has become reception, that is, the cultural influence of Blake’s writings on later culture, including the culture of other countries: poetry, literature, music and cinema. Each new era reveals fundamentally similar features and adds meanings to Blake: this process is going from symbolism and psychoanalysis to the present day.
Creator and Art in Hans Christian Andersen’s Novels
Authors: Korovin Andrey V.
Published: July 2021

The article deals with three novels by Danish writer Hans Christian Andersen, who is known worldwide as an author of fairy tales. In his novels The Improviser (1835), Only a Fiddler (1837) and Lucky Peer (1870) the main plot is built on the issue of relationships between a creator, an artist and the rest of the world. The theme of art is the one of the most important for the Romantic esthetics and Andersen discusses it in different ways in his novels. Philosopher S. Kierkegaard criticized Andersen’s conception of how a talent interacts with the reality as naive and fictive, but Andersen gives different visions of the artist’s way in these texts. The first novel is the history of an Italian boy who has an outstanding talent of improvisation. He receives assistance from people and eventually becomes a real artist in Romantic sense of the word. The hero of the second novel Christian is partly alter ego of the author, a boy from a poor family who tries to realize his musical talent but has not enough spiritual power to overcome all troubles in his life. He cannot find himself as an artist and dies. The title of the last novel is relevant to its subject — it is a story about the rise of а talented singer and his death on the top of fame. These three heroes are different types of interaction between a creator and reality in its romantic interpretation.
Figure and Scope of Ideas of Ludwig Wittgenstein in W.G. Sebald’s Austerlitz
Authors: Sokolova Elizaveta V.
Published: July 2021

The article examines the multilevel influence of the personality and ideas of Ludwig Wittgenstein (1889–1951) on the literary text of the significant German writer (and academic literary researcher) of the 1990s W.G. Sebald (1944–2001) — first of all, on the example of his final work, the novel Austerlitz (2001), in which the most important themes and main stylistic and artistic strategies of the writer culminate. It is shown that the features of this text, including ways and patterns of movement and unfolding of thought in it, reflect and echo Wittgenstein’s ideas on “family resemblance” as a hidden principle organizing human language and experience (Philosophical Investigations, 1953). Since the research methodologically relies on a systematic approach, within which the writer’s creative heritage is viewed as a unity with its own hierarchy, structure, network of internal and external correspondences, an assumption is made, confirmed by several examples from other writer’s texts, that the identified functions and ways of existence of L. Wittgenstein’s image and ideas are characteristic for the literary text of the writer as a whole.
Flg22-induced Ca2+ increases undergo desensitization and resensitization

Published: July 2021

The flagellin epitope flg22, a pathogen-associated molecular pattern
(PAMP), binds to the receptor-like kinase FLAGELLIN SENSING2 (FLS2), and
triggers Ca2+ influx across the plasma membrane (PM). The flg22-induced
increases in cytosolic Ca2+ concentration ([Ca2+]i) (FICA) play a
crucial role in plant innate immunity. It’s well established that the
receptor FLS2 and the key downstream component, reactive oxygen species
(ROS) burst, undergoes sensitivity adaptation after flg22 stimulation,
referred to as desensitization and resensitization, to prevent over
responses to pathogens. However, whether FICA also mount adaptation
mechanisms to ensure appropriate and efficient responses against
pathogens remains poorly understood. Here, we carried out detailed
analyses of [Ca2+]i increases upon two successive flg22 treatments,
recorded and characterized, for the first time, rapid desensitization
but slow resensitization of FICA in Arabidopsis thaliana.
Pharmacological analyses showed that the rapid desensitization might be
synergistically regulated by ligand-induced FLS2 endocytosis as well as
the PM depolarization. The recovery of desensitized FICA might require
to de novo FLS2 protein synthesis. FICA resensitization appeared
significantly slower than FLS2 protein recovery, suggesting additional
regulatory mechanisms of other components, such as flg22-related Ca2+
permeable channels. Taken together, we have carefully defined the FICA
sensitivity adaptation, which will facilitate further molecular and
genetic dissection of the Ca2+-mediated adaptive mechanisms in
PAMP-triggered immunity.

SCAD patients requiring revascularization.
Common things are common, but what is common? A foundation for probabilistic diagnosis.
Authors: Aberegg Scott , Callahan Sean
Published: July 2021

The well-known clinical axiom stating that “common things are common”
attests to the pivotal role of probability in diagnosis. Despite the
popularity of this and related axioms, there is no operationalized
definition of a common disease, and no practicable way of incorporating
actual disease frequencies into differential diagnosis. In this
expository essay, we aim to reduce the ambiguity surrounding the
definition of a common (or rare) disease and show that incidence – not
prevalence – is the proper metric of disease frequency for diagnosis.
We explore how a numerical estimates of disease frequencies based on
incidence can be incorporated into differential diagnosis as well as the
inherent limitations of this method. These concepts have important
implications for diagnostic decision making and medical education, and
hold promise as a method to improve diagnostic accuracy.

Bloom’s Taxonomy: Reforming Pedagogy Through Assessment
Authors: Chandio Muhammad Tufail , Nishat Zafar  , Solangi Ghulam Muhiuddin
Published: July 2021

The study analyses the scope and role of Bloom’s Taxonomy in reforming teaching-learning practices in the classroom. Bloom’s Taxonomy propounds that teaching-learning process and assessment items should transcend beyond lower domains of learning i.e. remembering, understanding and applying to the higher domains of learning namely analysing, evaluating and creating. However, this study establishes that teacher always teach in accordance with the normative assessment patterns and students also learn accordingly. In this case, if assessment system is predominantly focused on lower domains, the teaching-learning practices will never transcend to higher domains. This study employs Bloom’s Taxonomy to categorise and analyse each item included in the annual question papers designed by the Boards of Intermediate and Secondary Education (BISE) Karachi, Hyderabad, Sukkur and Mirpurkhas for the subject of English for grade XII. At Sindh province level, it has been found that 74% is exhausted for the lower domains whereas only 26% is used for higher domains. Given to the normative assessment practices, teachers and students would remain focused only on the lower domains, but by altering the course, the pedagogical practices and teaching-learning process in Sindh province can remarkably be reformed and transformed from sheer memorization and rote-learning to critical thinking, solution-making, knowledge-building process and analytical skills

In this reflective paper, I have presented my own experience of preparation for emergency remote teaching for one of my courses in one of the Canadian universities. I have mentioned in the paper the factors that were helpful in the preparation for remote teaching such as my own background knowledge of online learning, training for remote teaching, designing and developing the course, using synchronous and asynchronous, engaging students, and presences.
Pakistani English Stories for Children: Linguistic and Technical Analysis
Authors: Dar Muhammad Fareed , Sheba Sultan  , Khadija Shereen
Published: July 2021

The quality of language produced is greatly influenced by the quality of language input. Reading is a major source of language and knowledge input. In Pakistan, two types of books written in the English language are available for the reader. The first type includes the books written and published in Pakistan and the second type is of the books written by foreign authors published in or outside Pakistan. The purpose of this study was to analyze 5 story-books written and published in Pakistan. The linguistic analysis and technical analysis of the books were carried out to explore the kind of material which is being produced locally and is readily available to Pakistani children. The focus of the study was on the English language and technical components of the story-books. Findings of the study reveal that the storybooks contain several language-related problems and technical deficiencies in story writing elements, hence it is concluded that proofreading for language and technical refinement for the storybooks can help improve the work quality.

Authors: Yeler Mustafa , Ocak Gürbüz
Published: July 2021

This study is Investigation of the Relationship between Pre-service Teachers’ Learning Styles and Their Critical Thinking Disposition The study was carried out with the participation of 358 candidate teachers- 243 female and 115 males- who were identified by way of proportional sampling from among 612 freshmen students who study in different programs in the Faculty of Education at Burdur Mehmet Akif Ersoy University. Grasha-Reichmann Learning Styles Scales (1974) and Critical Thinking Tendencies Scales by Semerci (2016) were used as data collecting tools for this study. The data obtained by the application of these scales were analyzed using parametric tests t-test, ANOVA, Pearson correlation, two-way ANOVA and regression according to the nature and scope of the data. In all operations, p<.05 significance level was identified. It was found that there is a significant relationship at moderate level between the learning styles and the critical thinking tendencies of the candidate teachers. Depending on the variables such as age, gender, the type of the high school and departments, a moderate relationship was found between learning styles and critical thinking tendencies. While the common impact of age and learning styles; gender and learning styles; the high school type and learning styles were not significant, the common impact of department and learning styles were found to be significant at moderate level. On the other hand, when age and learning styles; gender and learning styles; departments and learning styles, and high school types and learning styles are taken into consideration together, it was found that each coupling could explain approximately 25% of the tendencies of critical thinking. In the light shed by these results, it is suggested that the learning styles and critical thinking tendencies must be considered together in teaching-learning processes designed for candidate teachers.
A Decentralized Multi Agent ANN Based Control Technique for Operation Cost Optimization of Isolated Microgrid Systems
Authors: Ullah Asad , Amin Salman , Haroon Shaikh Saaqib , Sajjad Intisar Ali , Shaukat Hammad
Published: July 2021

With an ever increasing electrical load demand and the associated fuel price to generate it, researchers are compelled to find alternate, cheap and environment friendly ways for power generation to cater to this techno-economic conundrum. Renewable Energy Sources (RES) are now being integrated in Distributed Generation (DG) based environment as a solution to this problem, hence resulting in Microgrids, with multiple sources and loads demarcating their footprint. Control and management of a diverse generation profile within a single microgrid is arduous and computationally intensive for a single centralized controller. This paper addresses this inherent problem and proposes a decentralized Multiagent based intelligent control technique to efficiently encompass the heterogeneous generation profile of Microgrids. Artificial Neural Network (ANN) based intelligent agents are deployed at the planning stage for each component of the Microgrid. These agents are responsible for maintaining individual local control parameters within the prescribed control margins, hence creating a multi-agent environment in a Microgrid structure. The proposed intelligent multi-agent control scheme is tested on a test system to furnish its merits over its traditionally employed counterparts. Simulation results show that ANN integration not only reduced the computational burden but also reduced the overall operating cost (around 10.2 %) by reducing the thermal generation.

Published: July 2021

In today’s manufacturing environment, there is always a need to use cost effective methods and materials for production purposes. Friction welding is one of such method that offers cost effectiveness and high productivity rate as compared to other similar welding processes. Friction welding process has been used widely in the manufacturing world. It is an adjustable and tolerant process that can join most engineering materials. It is a well-established welding process that can produce good quality weldment between similar and dissimilar materials. Due to this flexibility of use of different materials, it has been used in many applications such as aerospace, automotive and other related manufacturing industries etc. The main objective of this research is to study possibility of doing friction-welding on a typical lathe machine instead of doing it on a friction welding machine and also to check the reliability of the welded joint. Conventional Lathe machine was converted into a friction-welding machine by adopting a systematic procedure. The fixture of the attachment was designed, manufactured and installed and different parameters such as applied pressure and spindle rpm were tested in order to achieve the welding joint by friction. The materials used for welding were Stainless Steel 070M20 and Aluminum 2011-T3.

Published: July 2021

Wind resource potential is strongly influenced by the exposure, orientation of the terrain and the wind direction. In Pakistan, the northern areas have very attractive sites for wind power plants. However, due to non-standardized masts installed, the collected data are not reliable. Due to the unreliable nature of available data, the investors normally avoid the investing in the wind power projects. Various software and tools have been used so far for the feasibility analysis but due to unreliable data, the proper feasibility analysis is still out of sight. To overcome this deficiency, a feasibility study of a wind power project in the Hunza Valley of Pakistan using reliable data is presented in this paper. For this purpose, the RETScreen is used by exploiting the standard NASA’s (National Aeronautics and Space Administration) database. Since the developing countries are facing problems in the development of wind projects, it is envisaged that this approach will give an easy way to launch new clean energy projects.
Perspective of Bioenergy in Pakistan for Sustainable Eco-Friendly Energy Substitute: A Review
Authors: Maitlo Ghulamullah , Abbasi Sikander Ali , Korai Rashid Mustafa , Memon Abdul Ghaffar
Published: July 2021

Pakistan has remained an energy deficient country for the last few decades. The supply of electricity decreased in 2002-2007 against the exponentially increasing demand in Pakistan. In the meantime, severe load shedding was started across Pakistan that negatively affected the economic growth of the country. More than 63% of the population in rural areas live without electricity. The government cut down electricity supply eight to twelve hours per day in terms of load shedding that adversely affects the living standards and economic growth of the nation. In the world, Pakistan stands on 133 regarding ranking in energy consumption. Energy usage per capita in Pakistan is 482 kilograms of oil equivalent per year (kgoe/a) which is very low when compared with the industrialized countries. Besides that Pakistan strongly adheres with non-renewable energy options to mollify its energy demand. The import of fossil fuels to meet energy demand adversely affects the economy of Pakistan. This review helps in the identification of indigenous available biomass resources and their conversion processes for power production to improve power generation, living standards and economy of the country. The application of indigenous biomass resources for electricity generation will reduce the pressure caused by increased demand for energy.
A Regression Analysis Based Model for Defect Learning and Prediction in Software Development
Authors: Memon Mashooque Ahmed , Baloch Mujeeb-ur-Rehman Maree , Memon Muniba , Musavi Syed Hyder Abbas
Published: July 2021

The development of software undergoes multiple regression phases to deliver quality software. Therefore, to minimize the development effort, time and cost it is very important to understand the probable defects associated with the designed modules. It is possible that occurrence of a range of defects may impact the designed modules which need to be predicted in advance to have a close inter-association with the depended modules. Most of the existing defect prediction classifier mechanisms are derived from the past project data learning, but it is not sufficient for new project defect predicting as the new design may have a different kind of parameters and constraints. This paper recommends Regression Analysis (RA) based defect learning and prediction Defect Prediction (RA-DP) mechanism to support the defective or non-defective prediction for quality software development. The RA-DP approach provides two methods to perform this prediction analysis. It initially presents an association learning through RA to construct the regression rules from the learned knowledge required for the defect prediction. The constructed regression rules are used for defect prediction and analysis. To measure the performance of the RA-DP a regression experimental evaluation is performed over the defect-prone PROMISE dataset from NASA project. The outcome of the results is analyzed through measuring the prediction Accuracy, Sensitivity and Specificity to demonstrate the improvisation and effectiveness of the proposal in comparison to a few existing classifiers.
Sentiment Analysis based on Soft Clustering through Dimensionality Reduction Technique
Authors: Akmal Saba , Shahzad Asif Hafiz Muhammad
Published: July 2021

Clustering based sentiment analysis confers new directions to analyze real-world opinions without human participation and pre-tagged training data overhead. Clustering based techniques do not rely on linguistic information and more convenient as compared to other traditional machine learning techniques. Combining the dimensionality reduction techniques with clustering algorithms highly influence the computational cost and improve the performance of sentiment analysis. In this research, we applied Principal Component Analysis technique to reduce the size of features set. This reduced feature set improves binary K-means clustering results of sentiments analysis. In our experiments, we demonstrate the performance of the clustering system with a reduced feature set to provide high-quality sentiment analysis. However, K-mean clustering has its own limitations such as hard assignment and instability of results. To overcome the limitation of traditional K-means algorithm we applied soft clustering (Expectation maximization algorithm) approach which stabilizes clustering accuracy. This approach allows a soft assignment to cluster documents. Consequently, our experimental accuracy is 95% with standard deviation rate of 0.1% which is sufficient to apply the clustering technique in real-world applications.

Published: July 2021

The results of laboratory studies carried out to identify the possibility and effectiveness of technologies for the complex recycling of components of flue gases and wastewater from thermal power plants and industrial boilers are presented. The following factors were investigated: the degree of saturation of water solutions with CO2, the efficiency of using these solutions for the regeneration of cation exchangers, the properties of regeneration solutions intended for the regeneration of cation exchange filters prepared using components of flue gases obtained from the combustion of organic fuel in the laboratory by saturating water of various compositions, the degree of saturation of condensate and waste-water with components of flue gases, as well as the degree of regeneration of cation exchangers with such regeneration solutions. After research in the laboratory, a laboratory installation was created in an industrial environment to determine the properties of solutions obtained from wastewater and flue gases obtained after production processes at a power plant. The technologies were developed for the complex recycling of flue gases and waste-water from thermal power plants with the production of CO2 with a purity of 99.9%, technical nitrogen with a purity of 95%, special solutions for the regeneration of cation exchangers in water purification plants of industrial enterprises. The results obtained make it possible to minimize the volume of emissions into the atmosphere and the volume of waste-water from thermal power plants.

OBJECTIVE

Sodium–glucose cotransporter 2 inhibitors (SGLT2i) improve albuminuria in patients with high cardiorenal risk. We report albuminuria change in the Dapagliflozin Effect on Cardiovascular Events (DECLARE-TIMI 58) cardiovascular outcome trial, which included populations with lower cardiorenal risk.

RESEARCH DESIGN AND METHODS

DECLARE-TIMI 58 randomized 17,160 patients with type 2 diabetes, creatinine clearance >60 mL/min, and either atherosclerotic cardiovascular disease (CVD; 40.6%) or risk-factors for CVD (59.4%) to dapagliflozin or placebo. Urinary albumin-to-creatinine ratio (UACR) was tested at baseline, 6 months, 12 months, and yearly thereafter. The change in UACR over time was measured as a continuous and categorical variable (≤15, >15 to <30, ≥30 to ≤300, and >300 mg/g) by treatment arm. The composite cardiorenal outcome was a ≥40% sustained decline in the estimated glomerular filtration rate (eGFR) to <60 mL/min/1.73 m2, end-stage kidney disease, and cardiovascular or renal death; specific renal outcome included all except cardiovascular death.

RESULTS

Baseline UACR was available for 16,843 (98.15%) participants: 9,067 (53.83%) with ≤15 mg/g, 2,577 (15.30%) with >15 to <30 mg/g, 4,030 (23.93%) with 30–300 mg/g, and 1,169 (6.94%) with >300 mg/g. Measured as a continuous variable, UACR improved from baseline to 4.0 years with dapagliflozin, compared with placebo, across all UACR and eGFR categories (all P < 0.0001). Sustained confirmed ≥1 category improvement in UACR was more common in dapagliflozin versus placebo (hazard ratio 1.45 [95% CI 1.35–1.56], P < 0.0001). Cardiorenal outcome was reduced with dapagliflozin for subgroups of UACR ≥30 mg/g (P < 0.0125, Pinteraction = 0.033), and the renal-specific outcome was reduced for all UACR subgroups (P < 0.05, Pinteraction = 0.480).

CONCLUSIONS

In DECLARE-TIMI 58, dapagliflozin demonstrated a favorable effect on UACR and renal-specific outcome across baseline UACR categories, including patients with normal albumin excretion. The results suggest a role for SGLT2i also in the primary prevention of diabetic kidney disease.

Új szakcsapat születése az I. világháborúban: a vegyivédelem
Authors: Őze Zoltán
Published: July 2021

Az I. világháború, amelyet úgy emlegettek, hogy a „háború, amely véget vet minden háborúnak”, számtalan olyan technikai újítást hozott, amelyek örökre megváltoztatták a hadviselés arculatát. Ez volt az a háború, amelyben megjelentek a harckocsik, a tengeralattjárók, a repülőgépek, a lángszórók és a lövészárkok néma gyilkosai, a vegyi fegyverek. A harci gázok tömeges bevetése kikényszerítette az ellenük történő védekezés eljá­rásrendjének, és ezzel együtt egy új szakcsapatnak a megszületését: ekkor alakult meg a vegyivédelmi szakszolgálat.

Neste documento propomo-nos descrever uma intervenção educativa num Centro de Acolhimento de crianças, na qual implementámos um conjunto de atividades, que permitiram que um grupo de doze crianças interagisse com animais não humanos. Das diversas atividades realizadas, iremos expor duas delas, que se designam: «Atrair aves para o jardim da instituição de acolhimento» e «Formigando». Com a apresentação destas duas atividades, pretendemos demonstrar uma forma de promover diversas aprendizagens em crianças acolhidas em instituição, com elevada vulnerabilidade vivencial e emocional, fundamentando as nossas opções em estudos da neuroaprendizagem, da biologia do medo e das interações com animais. Durante toda a intervenção educativa, foi nosso propósito possibilitar às crianças momentos de aprendizagem e de bem-estar, no qual o «humano» se desenvolvesse através do «não humano» e que as mesmas estabelecessem ligações neuronais concorrentes com ligações prévias, em que o medo era prevalente. Esta intervenção educativa foi desenvolvida no âmbito de uma parceria entre a Universidade do Algarve e o referido Centro de Acolhimento, na qual um grupo de doze crianças interagiu com animais não humanos, nomeadamente aves e formigas.

Published: July 2021

Although Palm Oil Mill Effluent (POME) can be used as a raw material for biodiesel production, the POME contains an excessive amount of Free Fatty Acids (FFA), necessitating a preliminary process and esterification. POME is degummed using phosphate acid and bleached with carbon active. Additionally, this study used KOH-impregnated zeolite to reduce FFA. The purpose of this study is to determine the effect of adding impregnated zeolite on esterification. POME was heated to 600C for 30 minutes, then degumming with 3 % of phosphate acid for 30 minutes, followed by bleaching with carbon active with a comparison ratio of 8:3 at 1000C for 1 hour, and finally, esterification with 3 percent impregnated zeolite from the POME weight at 600C for 4 hours. The analysis was conducted using titration methods to determine the FFA of each esterification. The data will be compared between zeolite and non-zeolite degumming, bleaching, and esterification. The results indicated that the most effective method for reducing FFA was degumming, bleaching, and esterification with zeolite.

The suitability of land for C. konishii was evaluated using the analytic hierarchy process (AHP) method, which included multiple criteria, such as elevation, soil, climate, and vegetation characteristics. 120 different sites of C. konishii were studied and the model approximations were verified by a confusion matrix. The subsistence of C. konishii was mainly affected by topographic features (elevation, slope) and soil (soil texture) conditions. 15 variables were selected for the ecological analysis and construction of the land suitability map. They were combined into four main groups for weights approximation. The weights obtained by AHP were calculated as follows: topographic features (65%), soil (21.3%), climate conditions (7.4%), and vegetation type (6.3%). The total area with the highest suitability was estimated at 4, 6, 2 and 8% of the province area in Son La, Ha Giang, Thanh Hoa, Nghe An, respectively. The suitable areas for planting were located in Mai Son, Muong La, Moc Chau, Sop Cop districts of Son La province; Hoang Su Phi, Xin Man districts of Ha Giang province; Muong Lat district of Thanh Hoa province; Que Phong, Ky Son, Tuong Duong, Con Cuong districts of Nghe An province. Nghe An province has the largest suitable area for planting. The estimated AHP accuracy was 91.6%, which indicates that the approach is reliable for forestry management. The current study will provide a ground to the local population for the selection of suitable lands, ensuring the sustainability of natural resources, sustainable use and quality forest production.
Saudi Female EFL Undergraduates’ Knowledge, Perceptions, Problems, and Suggestions for Research Method Courses
Authors: Musaed Alghizzi Talal
Published: July 2021

This study aimed to analyze English as a Foreign Language (EFL) students’ knowledge and perceptions of research method courses in the Department of English Language and Literature, at Imam Mohammad Ibn Saud Islamic University (IMSIU). It also investigated the problems that students encounter and offered some suggestions for improving these courses. The significance of the study is that such topic has never been investigated before in such context. The study participants were 1,022 students (Levels three, four, five, six and seven) who voluntarily filled out a questionnaire consisting of sections on four factors/themes: knowledge, perceptions, problems, and suggestions. The collected data were analyzed using IBM SPSS Statistics software to compare the students’ answers, and a one-way analysis of variance test was used to detect the differences between academic levels regarding each theme. The results showed that regardless of the students’ academic levels, all of them agreed on studying and therefore knowing the research basic components; however, regarding the elements constituting each of these basic components, significant differences were found between the five groups. The results also indicated that these students have positive perceptions of the courses even though they encountered some research-related problems such as in knowing all or some research basic components and their specific elements; writing all or some of them; citing, summarizing, and paraphrasing sources; allocating primary and secondary resources; collecting and analyzing data; and consulting research manuals. Finally, all students agreed that it would be helpful if they were assigned individual research supervisors and coauthored an article with them, a research course was taught in all academic levels for a bachelor’s degree, a research club was established, and research seminars were held.

An Analysis on Very Deep Convolutional Neural Networks: Problems and Solutions
Authors: Pricope T.-V.
Published: July 2021

Neural Networks have become a powerful tool in computer vision because of the recent breakthroughs in computation time and model architecture. Very deep models allow for better deciphering of the hidden patterns in the data; however, training them successfully is not a trivial problem, because of the notorious vanishing/exploding gradient problem. We illustrate this problem on VGG models, with 8 and 38 hidden layers, on the CIFAR100 image dataset, where we visualize how the gradients evolve during training. We explore known solutions to this problem like Batch Normalization (BatchNorm) or Residual Networks (ResNets), explaining the theory behind them. Our experiments show that the deeper model suffers from the vanishing gradient problem, but BatchNorm and ResNets do solve it. The employed solutions slighly improve the performance of shallower models as well, yet, the fixed deeper models outperform them.
