BACKGROUND.
Delayed cerebral ischaemia (DCI) following aneurysmal subarachnoid haemorrhage (aSAH) is a major cause of complications and death. Here we set out to identify high-performance predictive biomarkers of DCI and its underlying metabolic disruptions using metabolomics and lipidomics approaches.
METHODS.
This single-centre retrospective observational study enrolled 61 consecutive patients with severe aSAH requiring external ventricular drainage between 2013 and 2016, among them 22 experienced a DCI. Blood and cerebrospinal fluid (CSF) were sampled within the first 24 h after admission. We carried out LC-MS/MS-based plasma and CSF metabolomic and lipidomic profiling together with total fatty acids analysis.
RESULTS.
We identified a panel of 20 metabolites that together showed high predictive performance for DCI (area under the receiver operating characteristic curve: 0.968). This panel of metabolites included lactate, cotinine, salicylate, 6 phosphatidylcholines, and 4 sphingomyelins. Early biological disruptions that might explain the subsequent DCI found systemic hypoxia driven mainly by higher blood lactate, arginine and proline metabolism likely associated to vascular NO, dysregulation of the citric acid cycle in the brain, defective systemic energy metabolism and disrupted ceramide/sphingolipid metabolism. We also unexpectedly found a potential influence of gut microbiota on the onset of DCI.
CONCLUSION.
We identified a predictive metabolomic/lipidomic signature of further DCI in aSAH patients at admission to a NeuroCritical Care Unit. This signature is associated with significant systemic and cerebral biological dysregulations and reveal a potential link between DCI and gut microbiota. We conclude that targeting early peripheral hypoxia could help in preventing DCI.

Authors: Alam Khairul Habib , Rohen Yumnam , Albargi Amer Hassan , Hussain Aftab
Published: June 2023

Here, we discuss the idea of α-θ-E-Geraghty Pata proximal contraction and weak ϕ-α-θ-E-Geraghty Pata proximal contraction by merging contraction criteria put forth by Pata and Geraghty utilizing the α-θ-proximal admissibility. In both standard as well as partially ordered metric spaces, for such proximal contractions, we present proximity point results for both single as well as multivalued mappings. We also investigate the existence of coupled fixed point for α-θ-E-Geraghty Pata type contractions in regular metric space. Numerous findings in the literature are generalized, expanded upon, and unified by these findings. We provide an application of fractional differential and few examples to demonstrate how outstanding our findings are.

Authors: Dardiri Mohamed El , El-Tantawy Ashraf , Elmoez Khalid Abd , Sayed Haydy H. , Elbadry Hytham , Ibrahim Omneya
Published: June 2023

Background: Substance Use Disorders are serious health issues that have been linked to numerous clinical correlations and mental health comorbidities. One of the most important health dangers linked to substance addiction was suicide. The current study aims to investigate the phenomena using a bio-psycho-social framework. The aim was to investigate the risk of suicide in a sample of substance use disorders patients. A case control comparison was performed between 190 substance abusers versus 30 controls. Addiction Severity Index, Beck Suicidal Ideation Scale, Arab Religiosity Scale, Socioeconomic Status Scale, as well as multiple historical variables, have been investigated.
Results: Suicidality was prevalent among alcohol and opioids abusers, poly substance abusers, those with a family history of suicide, and those with a history of a previous attempt. Having a positive family history of suicide could predict an 8.3 point rise in Beck Suicidal Ideation Scale score, while having any previous attempt of suicide could predict 9.04 point rise in Beck Suicidal Ideation Scale score. Suicidality scores correlated with Addiction Severity Index scores, and indirectly with socioeconomic status and Religiosity. Combinations of drugs with other mental illness showed a significant predictive effect on suicidality score.
Conclusion: Suicidality is expected among substance abusers, and is affected by multiple bio-psycho-social variables.
To Investigate the Structural, Electronic, and Optical Characteristics of 2D Hetero-atoms Al, N, B-doped-Graphene Composites For Photocatalytic Applications: A DFT Study
Authors: Jameel Muhammad Hasnain , Roslan Muhammad Sufi bin , Agam Mohd Arif Bin
Published: June 2023

Two-dimensional (2D) layer structure graphene-doped composites have been confirmed to be an efficient and appropriate material to build effective photo-catalysts with enhanced catalytic efficiency for wastewater and industrial wastage. Graphene exhibits a proficient 2D layer structure, very large conductivity, better-quality electron mobility, and remarkably high surface area with large active sites for the best photocatalytic activity. In the current research structural, electronic, and optical characteristics of 2D Graphene doped-composites are calculated using a first-principles calculation. To use a generalized gradient approximation (GGA) and an ultra-soft pseudopotential (USP), the impact of Aluminium (Al), Nitrogen (N), and Boron (B) on structural, optical, and electronic characteristics of Graphene doped-composites are investigated. By substituting Al, N, and B in Graphene, extra gamma sites are produced into the energy bandgap (Eg). Owing to the difference in ionic radii of Al, N, and B the band gap is found to remarkably increase from 0 to 1.75 eV. The nature of the band gap is found direct. A noteworthy increment is found in Eg as a result of optical conductivity increase of 2.5 to 4.0. Due to the inclusion of Al, N, and B, the energy absorption peaks are increased and shifted to larger energy in the UV-visible spectrum. 2D layer structure doped-Graphene composites have high optical conductivity, refractive index, and energy absorption is an appropriate material for photocatalytic application.
Quantitative Determination the Role of the Intra-bandgap States in the Kinetics of Water Photooxidation over Hematite Electrodes
Authors: Zhang Shufeng , Leng Wenhua
Published: June 2023

The intra-bandgap states on the hematite (α-Fe2O3) electrodes are believed to play an important role in water photooxidation. Yet, it is not fully understood how the intra-bandgap states are involved in the reaction. In this work, the role of the intra-bandgap states in water photooxidation on the α-Fe2O3 electrodes is investigated by a combination of multiple (photo-) electrochemical techniques and operando spectroscopic methods. Two kinds of surface states are observed on the electrodes during water photooxidation, and their role are quantitatively determined by the correlation with the steady state photocurrent. It is demonstrated that the intrinsic electronic surface states close to the conduction band can act only as the recombination center for the photocarriers while water photooxidation on the electrodes is dictated by the photogenerated surface states at higher energy level with a first reaction order for the surface holes. More importantly, the photogenerated surface states are revealed to be the reactant in the rate limiting step of water photooxidation. These findings in this study may be beneficial to elucidate the actual function of the surface states, and provide mechanistic insights into the oxygen evolution on the α-Fe2O3 photoanodes.

Patients with cardiovascular long COVID syndrome and cardiac magnetic resonance (CMR) scans were included prospectively into the Vienna PostCoV Registry between March 2021 and March 2023 (EC: 1008/2021, clinicaltrials.gov NCT05398952; n=240). Clinical symptoms, age and sex, time between COVID-positivity and vaccination and CMR, as well as CMR findings were recorded. After medical treatment, clinical assessment and CMR was repeated in 67 patients with pathological CMR findings showing myopericarditis, pericardial effusion or cardiac functional abnormalities. Blood pressure and condition-adapted heart failure treatment led to a significant increase in left ventricular ejection fraction. Low-moderate doses of NSAIDs for 3 months significantly reduced pericardial effusion. Clinical symptoms improved markedly with a decrease in CMR abnormalities. In conclusion, medical treatment of cardiac/cardiovascular long COVID syndrome related to CMR abnormalities led to significant improvement in ejection fraction and decreased pericardial effusion, and were associated with improvements in the cardiovascular long COVID complaints.

Published: June 2023

Twitter is an online social network where people share and read the messages called as tweets. Twitter dropped the 140-character limit for private messages within its network. The new limit is 280 characters or Unicode glyphs. People share thoughts in their minds on twitter. Thoughts can be new stories, ideas, and their views about any popular events such as election poll, sports, movies, breaking news etc. Tweets can be used to predict the results of the events by finding the polarity intentions. Intention can be positive, negative or neutral. The paper aims to provide a subjectivity ratio method to obtain the polarity intention. It presents the algorithm for the subjectivity ratio method and its analysis, which shows that the subjectivity ratio method works faster for large data.
Harris hawks optimisation algorithm for the multi-objective portfolio optimisation with transaction costs
Authors: Saïb Nassir-Ud-Diin Ebrahim , Cheeneebash Jayrani , Gopaul Ashvin
Published: June 2023

The portfolio optimisation problem (POP) is a financial engineering problem where an investor is faced with the issue of allocating wealth amongst a set of assets so as to obtain a fair balance between the expected return and risk of a portfolio. In this paper we consider the multi-objective POP subject to the cardinality, quantity and pre-assignment constraints and study the cases when transaction costs are omitted and considered in the model. In order to solve this problem, the Harris Hawks Optimisation (HHO) algorithm is employed. Given the combinatorial nature of the constrained POP, a uniform crossover operator is incorporated in the exploration phase of the HHO that deals with the combination of assets for each candidate portfolio. We first test the applicability of the algorithm to the unconstrained problem and show that it is capable of obtaining highly accurate results. Then the suitability of the modified HHO is tested with seven publicly available datasets and compared against well-known heuristics. Five performance metrics were used to evaluate the performance of the algorithms and the results obtained proved the efficacy and superiority of the HHO over the other methods even in the presence of transaction costs.
Decision-making based on sustainability analysis using GREENSCOPE
Authors: Dias Ricardo N. , Filipe Rui M. , Matos Henrique A.
Published: June 2023

Current economic and environmental pressure encourages companies to invest and reform processes in a sustainable way. However, the decision on the best sustainable investment in a given industry may not be as straightforward as given by the independent economic and environmental indicators. Analyzing such indicators for investment in process alternatives is a complex multiobjective decision making (MODM) process. Many MODM methods can help solve this problem, GREENSCOPE suggests using the Addictive Utility Method (AUM), which may have some shortcomings. In this work, the Analytic Hierarchy Process (AHP) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) are applied to the indicator scores obtained with the GREENSCOPE methodology. AHP is applied with Marginal Rare of Substitution (MRS), to obtain the priority matrices. MATLAB was used to apply the MODM methods and also to determine, through an algorithm, the appropriate number of indicators to be used. Three cases were studied, namely a biorefinery plant, and two academic case studies on the production of acetaldehyde from ethanol and propylene glycol from glycerol. The two academic cases were modelled in Aspen Plus, to obtain process data, and linked to GREENSCOPE using MATLAB. The methodology was applied in some proposed alternatives where the sustainability improvement of energy integration and material recycling was tested. The new methodology was able to identify the more sustainable case among the alternatives. This methodology based on TOPSIS proved to be the best choice, avoiding the weighting of indicators, and providing an expected analytical decision among alternatives.
Evaluation of Health Sciences Faculty Students' Knowledge Levels on Microbiota and Health
Authors: YILMAZ Ozgenur
Published: June 2023

The importance of microbiota on health is an important topic that has been partially clarified and is still being illuminated. Individuals with health-related expertise are expected to be more familiar with the concepts of the microbiome and microbiota. However, some students who have not graduated and are studying in health-related fields do not understand concepts such as microbiota, microbiome, probiotics, and prebiotics, or they understand them incorrectly or insufficiently. The purpose of this study was to evaluate the knowledge levels of 4th grade students studying in the Nutrition and Dietetics, Midwifery, and Nursing departments about microbiota and health. A cross-sectional descriptive study was carried out on 133 students. The Microbiota Awareness Scale and Information Form were conducted online via a questionnaire survey created in Google Forms. It was determined that microbiota awareness, general information, product knowledge, chronic disease, and probiotic and prebiotic knowledge sub-dimension scores of the students whose departments were nutrition and dietetics were higher than the nursing and midwifery students. Furthermore, 78.9% of the students did not attend a "Microbiota and Health" conference, congress, seminar, or training. As a result, it is suggested that education programs focusing on the relationship between microbiota and health be organized, or that they be added to the curriculum, and that students be educated about microbiota and health.

Authors: Little Matthew , Dodd Warren , Grewal Ashmita , Stringer Eleah , Richter Abby
Published: June 2023

Background:
Food insecurity is linked with suboptimal diet and comprises an important risk factor for nutrition-related chronic diseases. Fruit and vegetable prescription programs are designed to improve access to healthy foods, but there is limited evidence on the impacts of such programs in the Canadian context. The objective of this study was to assess changes in food security, food consumption, and health among adult participants of a fresh food prescribing program in Guelph, Ontario, Canada.
Methods:
A total of 57 food insecure individuals with ≥ 1 cardio-metabolic condition or micronutrient deficiency received fresh food prescriptions from their healthcare practitioner and received weekly vouchers for an online produce market. We used a single-arm repeated-measures evaluation and paired t-tests to assess changes in food security, food intake, self-reported health, and blood biomarkers of cardio-metabolic, and nutritional health. Linear regression models were used to assess factors associated with change in fruit and vegetable consumption and voucher usage.
Results:
Food insecurity improved following the proportion of participants classified as severely food insecure fell from 47.4–24.5%. Consumption of fruit, dark green vegetables, orange vegetables, and other vegetables increased during the intervention (p < 0.05). Mean fasting insulin and ascorbic acid levels improved (p < 0.05). Worse food insecurity and lower fruit and vegetable consumption at baseline, as well as more frequent interaction with healthcare providers, were associated with a greater increase in fruit and vegetable consumption from pre- to post-intervention (p < 0.05).
Conclusions:
Fruit and vegetable prescription programs may improve food security and increase fruit and vegetable consumption, but further research is needed to determine their long-term health impacts.

Authors: He Yujie , Zhang Qian , Wang Wenjie , Hua Jie
Published: June 2023

The soil, sediment, and water surrounding abandoned tailings can be regarded as both sinks and sources of pollution. Taking the surrounding environment of abandoned tailings viewed as a whole, and conducting a comprehensive environmental pollution assessment is the basis of tailings pollution control and accurate management. we aimed to synthesize single-element pollution indicators and multi-element pollution indicators and propose a comprehensive pollution status evaluation method for abandoned tailings and their surrounding environment. Provide effective tools for tailings classification management on a regional scale. First, the single-element contamination index and multi-element contamination index were selected to evaluate the contamination risk of agricultural soil, surface water, groundwater, and sediment. The comprehensive pollution risk score(CRS) of each element in the environment was calculated. Then the overall score of pollution status (P) of the tailings site and its surrounding environment was obtained based on the weighting coefficients of the risks for different environmental receptors. Finally, the potential sources and migration paths of pollutants were determined by combining PMF and GIS mapping. The mean contents of heavy metals in the soils and sediments were higher than the average values in China and background values except for Cr. The mean concentration of Cd, Cu, Pb, Zn, and As in surface water and the mean concentration of Cd, Cu, and Zn in grounder water exceeded the value specified in their corresponding standards. The comprehensive pollution risk score of each element in the environment surrounding the tailings from the largest to the smallest are: CRS Cd (27) > CRS Cu (22) > CRS As (18) > CRS Zn (16) > CRS Pb (14) > CRS Cr (9). It was shown that Cd and Cu were the elements with the highest risk of environmental pollution Within the entire environmental system. The overall score of pollution status of the environment around the tailings in this study was calculated to be 5.37 points, which belongs to the Ⅲ level. The superposition of natural sources and mining activities is the most important factor in soil and sediment contamination. The pollution situation in the area is serious and the environmental quality is worrying, which threatens the safety of agricultural products and human health, and the comprehensive evaluation method can effectively assess the current situation of environmental pollution around the tailings.

Authors: Prabhakar Archana , Grison Elise , Lhuillier Simon , Leprévost Florian , Gyselinck Valérie , Morgagni Simone
Published: June 2023

Understanding how individuals mentally perceive and navigate urban spaces is a significant subject in spatial cognition, and it is crucial for urban planning and design. Transit maps are central in these matters, as they present and represent information about public transport systems. They primarily include the positions of transit lines, transit stops and transfer stations, along with the connections that exist between them (Guo, 2011). Through a series of interviews with more than twenty Londoners including a “sketch mapping” phase (Lynch, 1960), Vertesi (2008) showed that the Tube Map depicting the London Underground transit system has distorted Londoners’ perception of their city, with residents now identifying the Tube Map as a plausible representation of what London is. Our research aims to further her pioneering work and shed light on the connection between people's mental representations of metropolitan areas and the schematic representations of their corresponding public transport networks. We present two studies that confirm an association between peoples’ representations of metropolitan areas and the schematic representations of their respective public transport networks. Our studies take into consideration cognitive biases and distortions revealed in the literature on spatial cognition to underlie the construction of mental representations of geographic spaces where public transport networks have since long put down roots in citizens’ culture and habits with a specific focus on Paris, London and Berlin metropolitan areas.

Authors: Santos Nathanael Risson , Alves Elcio Cassimiro , Kripka Moacir
Published: June 2023

The growing scarcity of natural resources drives the construction sector to seek solutions and technologies where materials are employed not only for greater cost-effectiveness but also for improved performance and increased sustainability. This study aimed to use optimization in the design of reinforced concrete beams, aiming to reduce costs, CO₂ emissions, and concrete cracks. Considering the conflicting nature of the objectives, a multi-objective optimization was performed using the Non-dominated Sorting Genetic Algorithm (NSGA-II). The design variables considered were the dimensions of the cross-sectional area and the number of steel bars in the bottom layer of the beam. Beams with varying spans and concrete strengths were optimized, and Pareto frontiers were obtained. The results allowed for the identification of the most relevant parameters for each objective considered, as well as the behavior of each variable in obtaining the optimized solutions. Among the main conclusions, it was found that the least costly solutions also correspond to the lowest impact and that greater width can be advantageous in increasing the durability of the beams.

Published: June 2023

Objective
To determine the diagnostic yield of exome sequencing (ES) above that of chromosomal microarray analysis (CMA) or karyotyping in fetuses with skeletal dysplasia (SD) from various perspectives.
Methods
This systematic review was conducted in accordance with PRISMA criteria. Searching PubMed, EMBASE, Scopus, and Cochrane Library, we identified studies describing ES, next-generation sequencing, and/or genes panel in fetuses with SD. Inclusion criteria were: (i) fetuses diagnosed with suspected SD by prenatal ultrasound; (ii) more than 5 fetuses included; (iii) normal karyotype and CMA results. Two reviewers completed the data of Prenatal (Ultrasound) phenotype and genotype information collection independently and merged it.
Results
We identified 18 studies with data on ES diagnostic yield including 599 individuals with SD. Overall, a pathogenic or likely pathogenic variant was found in 306 fetuses, resulting in a 60% (95% CI, 48–72%) diagnostic yield. The number of gene mutations detected was 346, involving 74 genes related to SD and 23.7% of novel variants. The targeted skeletal gene panel showed a diagnostic yield of 76% (95% CI, 62–89%).
Conclusions
The application of ES in fetuses with SD and normal karyotype or CMA can provide a considerable diagnostic yield. The benefits of using ES in selected groups will be more obvious.
Drivers and mechanisms of pastoral system adaptation to climate change: An assessment in a French Alps case study region
Authors: Targetti Stefano , Hinojosa Leonith , Mouléry Michel , Napoléone Claude
Published: June 2023

Alpine pastoral systems are examples of human-managed landscapes where farming practices are traditionally adapted to semi-natural forage resources. Climate change effects will likely drive farming management with relevant socioeconomic and environmental impacts on pastoral systems and mountain communities. However, pastoral systems are complex socio-ecological systems driven by a range of drivers such as policies and institutions that trigger a range of direct and indirect feedbacks and influence the adaptation response to climate change. We present a participatory approach based on different sources and types of knowledge, building of cognitive maps with local farmers, and testing of scenarios featuring different impacts on the local pastoral system. The approach is aimed at identifying the drivers of vulnerability, understanding the cause-effect relationships between the main stress factors affecting the local pastoral system and at discerning the “concurrent” factors that enable or constrain farmers’ adaptation capacity. Our results outline that unpredictability linked to climate variability is relevant for farmers’ decisions. Nonetheless, predation is clearly the most important threat hindering the utilization of upland grasslands. The results discussed with local stakeholders point to an attentive consideration of the expected increase in farmers’ workload linked to predation, climate variability stresses, and agricultural policy. Strategies aimed at enhancing the availability of skilled shepherds result as the most effective to decrease the workload for farmers, increase the adaptive capacity of the local pastoral system, and thus contribute effectively in contrasting the abandonment of mountain grasslands.
To harvest or not? Tradeoffs between SOC maintenance and overall environmental performance of harvesting crop residues for the bioeconomy
Authors: Díaz Christhel Andrade , Zamora-Ledezma Ezequiel , Hamelin Lorie
Published: June 2023

The transition to zero-net emissions raises trade-offs between the services competing for sustainable carbon sources. Here, we performed a consequential LCA to understand the full environmental performance of managing 1 tonne of wet crop residue to produce sustainable marine fuels, while preserving or enhancing the SOC stocks in French croplands. Three management scenarios were considered: i) decay of crop residues on soils (reference), ii) conversion of crop residues to hydrotreated pyrolysis oil (HPO) to replace heavy fuel oil in maritime transportation, with biochar return to soil, and iii) conversion of crop residues to cryogenic liquefied bio methane (bio-LNG) to replace liquefied natural gas in cargo ships, with digestate return to soil. Besides the replacement of the fossil fuels, a system boundaries expansion was applied to account for the valorisation of the coproducts obtained along the whole supply chain of each system. Results per tonne of crop residues show, for all impacts assessed, a better environmental performance of using crop residues for maritime biofuels in comparison to their direct ploughing to soils, for all environmental impacts assessed. Notably, major GHG savings are observed, representing avoided emissions of 563 and 946 kgCO2etww− 1 of crop residues for the HPO and bio-LNG, respectively. The impact was scaled to the national potential that can be harvested for each pathway without losing SOC stocks (C-neutral harvest), implying a greater potential for the HPO pathway. While bio-LNG was the most performant pathway per tonne of residues (with the exception of marine eutrophication and particulate matter), the scaled results show greater savings with the HPO pathway, except for freshwater eutrophication and water scarcity. The results show that converting crop residues to biofuels while returning the recalcitrant coproduct of the conversion pathway to soils allows, in the HPO case, net environmental benefits for all the assessed environmental impacts as well as for SOC stocks. While bio-LNG shows net savings in most impacts, it shows a net impact for marine eutrophication because of the nitrogen losses associated with the digestate management. Overall, the results do not show, for the assessed pathways and impacts, a trade-off between SOC maintenance and net environmental impacts, if a C-neutral harvest is ensured with the co-product return to soil. This reflects the importance of fossil fuels substitution beyond the sole climate impact.

Developing Speaking Skills Using Two Classroom Techniques: A Case Study of Non-English Major Second-Year Students at Ho Chi Minh City University of Food Industry
Authors: Ngan Ha Le Vu
Published: June 2023

From the fact that students are often reluctant to spend time practicing speaking because oral English is not examined in the final exams for English 1, English 2, and English 3 at HUFI, the author believes that lecturers need to provide encouraging activities to boost the students’ speaking skill. The purposes of this research were to study and compare speaking skills of Non-English Major Second-Year students before and after using two classroom techniques, and to study the students’ attitude towards teaching English speaking skills using the three classroom techniques. The sample group is a English 2 class consisting of 42 students, 26 males and 16 females, classified by high, medium, and low according to their abilities of English speaking proficiency level. The author’s research tools were 4 units from Life Student’s Book Intermediate, an English-speaking ability test, and an attitude survey. The quantitative data were acquired from the speaking test and the students’ attitude towards English speaking class survey. The study's findings were quite positive. Firstly, 40 out of 42 students passed the speaking examination with marks from 3.5 marks to the maximum marks of 5. Secondly, data from the attitude questionnaire showed that students’ significant improvement in their enthusiasm for speaking English and their higher confidence in their English ability. Last but not least, the learners’ attitudes toward English speaking class using the three techniques were rated as satisfied. In the light of the study, it could be inferred that applying two techniques of telling story and drama – dialogue fully facilitate both the male and female students to develop their speaking skills in a more motivated way.

The Relationship Between Mindfulness and Second Language Acquisition Under Neurolinguistics Perspectives
Authors: Son Pham Ngoc
Published: June 2023

Mindfulness has been proposed as a technique for assisting people in overcoming stress and anxiety in daily life. Furthermore, mindfulness has academic benefits, particularly in second language acquisition (SLA), because it can increase verbal learning and memory through enhanced encoding, as well as influence academic accomplishment and awareness. This research intends to investigate the relationship between mindfulness and SLA from the perspective of neurolinguistics in order to elucidate the benefits of mindfulness in SLA. Using a qualitative research method, this work investigates the positive changes in the neural system caused by mindfulness practices based on neuropsychology and neurolinguistic theories, which may have an impact on SLA. As a result, mindfulness has an effective impact on the neural system, which can help learners enhance their concentration as well as their working memory, hence improving their academic performance on SLA. Given the benefits that mindfulness can provide to learners, it is advised that learners be taught some mindfulness practices during the teaching and learning process.

Descriptive and inferential statistics were applied in analyzing data, including correlation coefficient and multiple regression analysis. The results indicate that investors’ behavior is a significant factor in equity investment decisions. However, gender is not an influencing factor. Hence, the financial market may not always be guided by fundamental principles of standard finance but is largely influenced by investors’ irrationality and behavior. Then, it leads to excessive trading of securities, selling to gain portfolios, and overreaction and underreaction in the marketplace. Therefore, investors’ irrationality can be abated through training, professional advice, investment goal, and implementation of behavioral finance courses at professional and academic institutions.
