Effects of game-based learning in comparison to traditional learning to provide an effective learning environment—A comparative review

With the advancement in technology, various new learning strategies have been developed according to the requirement and learning environments of the learners. The game-based learning strategy is an advanced learning strategy in which a learner is fully engaged in the learning process. This learning strategy completely replaces the traditional learning strategy. A lot of research studies have indicated the improvement in the learning process by game-based learning strategy. The purpose of the current study was to compare the students’ learning outcomes with game-based and traditional learning strategies by descriptive and statistical way. A total of 26 articles published from 2012 to 2021 were selected by following the inclusion and exclusion criteria. The literature review of previous studies indicated that game-based learning strategy proved to be a highly effective learning strategy in numerous disciplines under different learning environments. In the game-based learning strategy, the learners are highly engaged in the learning process. Keywords: Game-based learning, traditional learning strategy, effective, engagement;

Multi-scale Machine Learning Prediction of the Spread of Arabic Online Fake News

There are a lot of research studies that look at "fake news" from an Arabic online source, but they don't look at what makes those fake news spread. The threat grows, and at some point, it gets out of hand. That's why this paper is trying to figure out how to predict the features that make Arabic online fake news spread. It's using Naive Bayes, Logistic Regression, and Random forest of Machine Learning to do this. Online news stories that were made up were used. They are found by using Term Frequency-Inverse Document Frequency (TF-IDF). The best partition for testing and validating the prediction was chosen at random and used in the analysis. So, all three machine learning classifications for predicting fake news in Arabic online were done. The results of the experiment show that Random Forest Classifier outperformed the other two algorithms. It had the best TF-IDF with an accuracy of 86 percent. Naive Bayes had an accuracy rate of 84%, and Logistic Regression had an accuracy rate of 85%, so they all did well. As such, the model shows that the features in TF-IDF are the most essential point about the content of an online Arabic fake news.

Use of Sugarcane Bagasse ash to Manufacture Light Weight Sustainable and Economical Concrete

Sugarcane bagasse ash is the admixtures used in this study. As we are an agricultural country and we harvest at least two crops yearly. These two crops are harvested every year and the yields produce a lot of waste in the form bagasse. This produces around at least 20 to 30% of waste of the total yield. Traditionally this waste is disposed off by burning it in the open fields. This acts as a fertilizer for the next crop, but it has a very bad effect on the environment as the smoke generated increases the air pollution. Hence using this material as partial replacements to cement will not only prevent open field burning but will also reduce the cement consumption. The density of sugarcane bagasse ash is lesser than cement and hence reduces the weight of the concrete manufactured using this as partial replacement to cement[1]. There are lot of research studies about manufacturing of light weight concrete using light weight aggregates[2]. Hence in addition to the light weight aggregates if light weight mineral admixtures are also used they will further reduce the weight of concrete thus leading to reduction in self weight of the structure. Hence including sugarcane bagasse ash in concrete as partial replacement to cement will not only reduce and recycle the waste but will also produce an economical, sustainable and light weight concrete mix.

Exploring the treatment effect of religious belief toward mental health with propensity score matching

PurposeAmong the research studies related to the relevance between religious belief and mental health, most of them highlight people with religious belief who tend to obtain mental comforting more easily. However, the research studies mentioned above were cross-sectional studies, and they only verified that religious beliefs and mental health are relevant, but they did not prove their cause-and-effect relationship. That is, they do not identify “due to people's religious beliefs, they have healthier mind” or “due to people's healthier minds, they have religious beliefs.” Therefore, the study aims to explore the benefit evaluation of religious belief affecting mental health.Design/methodology/approachThe study uses propensity score matching (PSM) and treatment effect (ATT) to carry out the causal inference between religious beliefs and mental health. First, the propensity score (PS) is calculated from the impact factors that affect people's religious belief before establishing counterfactual analysis based on the PS to analyze the effect of religious beliefs to further understand the difference of mental health index between people with religious belief and without it, and confirm the cause-and-effect relationship between them.FindingsReligious beliefs and participation are ubiquitous within and across populations. The associates between religious participation and health are considerably in great magnitude. Most of the research in the past related to religious beliefs and mental health only verified that religious beliefs and mental health are relevant but not proved its cause-and-effect relationship. This paper aimed to explore the causal relationship between religious belief and mental health. The experimental results showed religious belief has treatment effect toward “daily functioning,” “feeling affect,” “spirituality” and “mental health.” On a whole, religious belief can promote mental health.Originality/valueIn academic and practical circles, there are a lot of research studies exploring the relationship between religious belief and mental health. However, there is no research investigating the cause-and-effect relationship between religious belief and mental health. It also causes some questioning toward the relevant research studies. Therefore, the outcome of this study not only can clarify the legitimacy, importance, and practicality on the researches in the past but also provide the practical support for psychology and counseling.

EFL STUDENTS’ MOTIVATION IN WRITING, WRITING PROFICIENCY, AND GENDER

There have been a lot of research studies on the role of motivation in education and language learning. However, research on the role of motivation in the area of EFL (English as a foreign language) writing is a rare undertaking. This study aimed to examine the correlation between EFL students’ motivation in writing and their writing proficiency. It also compared female and male students in terms of their motivation in writing and their writing proficiency. This study involved 55 university students of English department (17 female and 38 male students) who were required to write essays and respond to a motivation in writing questionnaire. The results showed that there was a high correlation between the EFL students’ motivation in writing and their writing proficiency. It was also revealed that there were significant differences in the motivation in writing as well as writing proficiency of the female and male students. The findings of this study suggested that the EFL students who had a higher level of motivation in writing had better writing proficiency. The study also showed that female students outperformed male students in terms of both motivation in writing and writing proficiency.

In Situ Study of Structure-Activity Relationship between Structure and Tribological Properties of Bulk Layered Materials by Four-Ball Friction Tester.

Encouragingly, a lot of research studies have demonstrated that two-dimensional (2D) nanosheets applied as an additive in oils show preferable friction-reducing and wear resistance performance. However, the current issue was that an elusive way could be adopted to probe the structure–activity relationship between the structure and tribological properties of bulk layered materials due to the structural evolution during friction testing. In this study, we studied the structure–activity relationship between the structure and tribological properties of bulk layered materials (graphite, h-BN, WS2, and MoS2) by an in situ four-ball friction tester. The morphological and structural changes of the layered materials after in situ four-ball-milling were detected by a series of characterizations. This study revealed the friction-induced nanostructural evolution behaviors of bulk layered materials by a four-ball mode.

A Novel Method for Predicting Disease-Associated LncRNA-MiRNA Pairs Based on the Higher-Order Orthogonal Iteration.

A lot of research studies have shown that many complex human diseases are associated not only with microRNAs (miRNAs) but also with long noncoding RNAs (lncRNAs). However, most of the current existing studies focus on the prediction of disease-related miRNAs or lncRNAs, and to our knowledge, until now, there are few literature studies reported to pay attention to the study of impact of miRNA-lncRNA pairs on diseases, although more and more studies have shown that both lncRNAs and miRNAs play important roles in cell proliferation and differentiation during the recent years. The identification of disease-related genes provides great insight into the underlying pathogenesis of diseases at a system level. In this study, a novel model called PADLMHOOI was proposed to predict potential associations between diseases and lncRNA-miRNA pairs based on the higher-order orthogonal iteration, and in order to evaluate its prediction performance, the global and local LOOCV were implemented, respectively, and simulation results demonstrated that PADLMHOOI could achieve reliable AUCs of 0.9545 and 0.8874 in global and local LOOCV separately. Moreover, case studies further demonstrated the effectiveness of PADLMHOOI to infer unknown disease-related lncRNA-miRNA pairs.

A Study on the Delivered at Terminal (DAT) Term under Incoterms 2010

A remarkable feature of Incoterms 2010 is that Delivered Ex Quay (DEQ) from Incoterms 2000 was replaced by Delivered at Terminal (DAT). Unlike DEQ, DAT is a rule in which the seller fulfills his obligation by placing the goods at the buyer’s disposal after unloading them from the means of transportation at the named terminal at the named port or place of destination, and until the goods have been delivered. Thus, in this situation, the seller must bear all costs relating to the transportation and all risks of loss or damage to the goods. Although there has been a lot of research studies looking into Incoterms 2010, so far it seems that the DAT has not caught much attention from researchers working on international trade studies and this explains why no study about DAT exists. Therefore, the principal purpose of this study is to dig into the details of DAT and compare this with DEQ. Also, the results of the present study could help practitioners in related fields utilize DAT properly and allow it to be more widely used. More details will be presented in the manuscript.

THE IMPACT OF CLIL IMPLEMENTATION ON LEBANESE STUDENTS’ ATTITUDES AND PERFORMANCE

Content and Language Integrated Learning (CLIL) has been verified as an effective pedagogical approach by a lot of research studies carried out in many European countries. However, modest attempts have been made to prove its efficacy in Lebanon, where English Language is taught in many schools and universities as a first foreign language. The purpose of the present study was to examine the effectiveness of CLIL application on the academic achievement of Lebanese students and on their self-efficacy and attitude toward it. The participants (n=21) were first year university students enrolled in the faculty of pedagogy at the Lebanese University and majoring in teaching Math at elementary schools. Quantitative as well as qualitative data were collected by means of two questionnaires, pre-post tests and reflection logs. Descriptive statistics were calculated and a series of t-tests were conducted in order to address the questions raised in the study. The results of the study showed positive attitudes of students toward the implementation of CLIL and they revealed the efficacy of CLIL as a pedagogical approach in enhancing students’ self-efficacy and academic performance. Further research is recommended in order to determine the extent of CLIL effectiveness in other university contexts and across different majors and courses.

Treatment of glioblastoma with herbal medicines

BackgroundIn the latest years, a lot of research studies regarding the usage of active agents from plants in the treatment of tumors have been published, but there is no data about successful usage of herbal remedies in the treatment of glioblastoma in humans.MethodsThe phytotherapy involved five types of herbal medicine which the subjects took in the form of tea, each type once a day at regular intervals. Three patients took herbal medicine along with standard oncological treatment, while two patients applied for phytotherapy after completing medical treatment. The composition of herbal medicine was modified when necessary, which depended on the results of the control scans using the nuclear magnetic resonance technique and/or computed tomography.ResultsForty-eight months after the introduction of phytotherapy, there were no clinical or radiological signs of the disease, in three patients; in one patient, the tumor was reduced and his condition was stable, and one patient lived for 48 months in spite of a large primary tumor and a massive recurrence, which developed after the treatment had been completed.ConclusionsThe results achieved in patients in whom tumor regression occurred exclusively through the use of phytotherapy deserve special attention.In order to treat glioblastoma more effectively, it is necessary to develop innovative therapeutic strategies and medicines that should not be limited only to the field of conventional medicine. The results presented in this research paper are encouraging and serve as a good basis for further research on the possibilities of phytotherapy in the treatment of glioblastoma.

The prevalence of obesity in a sample of Egyptian psychiatric patients

Background The relationship between mental health and obesity has been studied in different types of research studies as it is considered very important. A lot of research studies have proposed several theories and mechanisms on how the two are linked, which should be reviewed and considered in the management plan of psychiatric disorders. Objectives The aim of this study was to find out the prevalence and correlates of obesity and overweight in a sample of psychiatric patients (inpatients and outpatients) with no history of pharmacological treatment in Al-Hussein University Hospital. Patients and methods This cross-sectional study was conducted during a 6-month-period on 130 psychiatric patients who were subjected to a semistructured clinical interview according to DSM-IV-TR criteria to diagnose psychiatric disorders. Obesity assessment was carried out by measuring the weight (kg) using a scale and measuring the height (m) to calculate the BMI, which is based on the BMI equation Wt (kg)/Ht2 (m2). Results The prevalence of obesity and overweight in psychiatric patients was 66.93% (22.31% were obese, and 44.62% were overweight). The prevalence of obesity was highest in bipolar disorder (41.38%), followed by depression (37.93%), schizophrenia (10.34%), anxiety disorder (6.9%), and finally substance abuse disorder (3.45%), but the difference was not statistically significant. There was a significant correlation between sociodemographic characteristics of patients and obesity and the distribution of psychiatric disorders. Conclusion The prevalence of obesity and overweight in psychiatric patients was relatively high, and this can occur with most psychiatric disorders, especially mood disorders, and were supposed to be due to other several mechanisms and risk factors other than the effect of psychotropic medications on the weight of psychiatric patients. Moreover, there are some demographic and social factors that may moderate or mediate the association between obesity and psychiatric disorders; thus, identification of overweight and obesity, associated risk factors, and efforts to prevent weight gain should begin at the initiation of mental health treatment.

Learning stories from IT workers – development of professional expertise

In the knowledge economy, many companies are well aware of the vital need to maintain the professional expertise of their workers at a high level. Though there have been a lot of research studies in the areas of professional expertise and workplace learning, few examined the learning pathways novice workers went through to become experts in their professions. Most of the research studies on expertise focused on the nature of expertise and few on its development. As for workplace learning research, most studies focused on the learning resources and methods workers used and the affordances of the workplace in making learning possible. Based on the accounts of expertise development collected from individual information technology (IT) workers in Hong Kong, this paper proposes a four-phase model of professional expertise development in the workplace and discusses its similarities to and differences from extant theories of expertise and skill development.

Tuned Imidazolium Ionic Liquids for Li-Ion Batteries: Compatibility with Li4TiO12/LiFePO4 and Cgr/LiFePO4 at Elevated Temperature

Lithium-ion batteries are the technology of choice for cellular phones and numerous other portable applications, due to the higher energy density at low weight and volume, the longer cyclability and lower self-discharge compared to other rechargeable batteries [1]. The concern about energy sources in the near future has made lithium ion rechargeable battery development into growth area which gained high momentum for its research activities. However, one of the biggest barriers of industrial development is the safety concern, which is mainly owing to volatile and flammable organic solvents used in the electrolyte. Ionic liquids (ILs) have attracted a great deal of scientific attention during the last decade due to their often unique combination of physico-chemical properties [2,3]. In particular, their exceptionally low vapor pressure at ambient temperature makes them interesting substitutes for many applications for which volatility of traditional organic solvents causes problems [4-5]. Although there have been a lot of research studies concerning ionic liquids that use imidazolium-based cations (for example, synthesis solvent and catalysis), the problem of a stability limit up to the redox potential of lithium metal has been pointed out, and there have been very few to no reports on rechargeable batteries that use lithium metal or graphite as electrodes. In this research study, we examined the battery characteristics of Cgr/LFP electrodes using an imidazolium based ionic liquid, with an electron donating substituent at the second position of the imidazolium cation. We aimed to improve the reduction stability of imidazolium-based ILs and to realize a battery system that has both safety and high performance by the molecular design of the room temperature ILs.In this work, we assembled and tested low-cost full cell configuration based on Cgr/LiFePO4 and containing ionic liquids (C1CnIm-NTf2 and C1C1CnIm-NTf2 / n=4, 6) based on bis(trifluoromethanesulfonyl)imide (NTf2 -) anion as the electrolyte media at 60°C. The cycle performance, life, electrochemical stability of this cell is reported and compared with LTO/LFP technology, along with some post-test and electrochemical diagnostics of the components after cycling. According to the results, the effects of extending the alkyl chain were confirmed: the best electrochemical stability and charge-discharge performance is observed with modified ionic liquids and long alkyl chain (figure 1). It is worth to mention that lithium ion Cgr/LFP cells employing IL-electrolyte were realized and found to deliver a full discharge capacity. Even more important, we could accomplish the cycling at 60°C, which can’t be safely achieved with conventional organic solvent based electrolytes.Reference[1] J.-M. Tarascon, M.

A Case Study on Sunflower Seed Oil Industries Waste Characterization, Classification and Treatment

The sunflower seed oil industry is one of the most important industrial sectors. As a part of the agro-industry, sunflower seed oil production makes a significant contribution to environmental pollution in Turkey. A lot of research studies are known to be performed on the characterization and treatment of olive oil production wastes in Turkey, but the nature, amount, waste loads and treatment of the wastewaters produced by sunflower seed oil industries have not been studied to a great extent. In this study, a typical sunflower seed oil refinery in the city of İzmir was selected as representative of this sector. Method of production is evaluated and the refinery is investigated for the characterization of its wastewaters. During the first part of the test program, quality of combined and separate raw effluents was investigated. Possible physical-chemical treatment alternatives were studied using bench-scale laboratory models. Based on these studies, the most practicable and efficient combination of treatment operations and processes were pointed out. Waste segregation possibilities for minimization of wastewater quantities are investigated. In these investigations treated effluent quality has been evaluated with respect to the discharge parameters set by the present Turkish environmental legislation.
