As part of this research, value investing and technical analysis principles will be combined to maximize returns for South African investors while optimizing volatility. As an emerging market, South Africa offers many opportunities for high growth in sectors where other developed countries cannot grow at the same rate. Investing in South African companies with significant growth potential can be extremely rewarding. Although the risk involved is more significant in countries with less developed markets and infrastructure, there is more room for growth in these countries. According to recent research, the offshore market is expected to outperform the local market over the long term; however, short-term investments in the local market will likely be more profitable, as the Johannesburg Stock Exchange is predicted to outperform the S&P500 over the short term. The instabilities in the economy contribute to increased market volatility, which can benefit investors if appropriately utilized. Price prediction and portfolio optimization comprise the two primary components of this methodology. As part of this process, statistics and other predictive modeling techniques will be used to predict the future performance of stocks listed on the Johannesburg Stock Exchange. Following predictive data analysis, Modern Portfolio Theory, based on Markowitz's Mean-Variance Theorem, will be applied to optimize the allocation of assets within an investment portfolio. By combining different assets within an investment portfolio, this optimization method produces a portfolio with an optimal ratio of expected risk to expected return. This methodology aims to provide a short-term investment with a stock portfolio that offers the best risk-to-return profile for stocks listed on the JSE by combining price prediction and portfolio optimization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20stocks" title="financial stocks">financial stocks</a>, <a href="https://publications.waset.org/abstracts/search?q=optimized%20asset%20allocation" title=" optimized asset allocation"> optimized asset allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction%20modelling" title=" prediction modelling"> prediction modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/168328/optimization-of-a-high-growth-investment-portfolio-for-the-south-african-market-using-predictive-analytics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168328.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3890</span> Flap Structure Geometry in Breakthrough Structure: A Case Study from the Southern Tunisian Atlas Example, Orbata Anticline</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soulef%20Amamria">Soulef Amamria</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sadok%20Bensalem"> Mohamed Sadok Bensalem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ghanmi"> Mohamed Ghanmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The structural and sedimentological study of fault-related- folds in the Southern Tunisian Atlas is distinguished by a special geometry of the gravitational structures. This distinct geometry is observable in the example of a flap structure in Jebel Ben Zannouch with the formation of a stuck syncline. This geometry can be explained by the mechanism of major thrusting in Orbata anticline in the occidental extremity of Gafsa chains, with asymmetrical flank dips and hinge migration kinematics. These kinematics was originally controlled by the Breakthrough structure; the study of this special geometry of gravity flap structure depends on the sedimentation domain, shortening ratios, and erosion speed. This study constitutes one of the complete examples of kinematic model validation on a field scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault-related-folds" title="fault-related-folds">fault-related-folds</a>, <a href="https://publications.waset.org/abstracts/search?q=southern%20Tunisian%20Atlas" title=" southern Tunisian Atlas"> southern Tunisian Atlas</a>, <a href="https://publications.waset.org/abstracts/search?q=flap%20structure" title=" flap structure"> flap structure</a>, <a href="https://publications.waset.org/abstracts/search?q=breakthrough" title=" breakthrough"> breakthrough</a> </p> <a href="https://publications.waset.org/abstracts/161486/flap-structure-geometry-in-breakthrough-structure-a-case-study-from-the-southern-tunisian-atlas-example-orbata-anticline" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161486.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3889</span> Percentile Reference Values of Vertical Jumping Performances and Anthropometric Characteristics in Athletic Tunisian Children and Adolescents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chirine%20Aouichaoui">Chirine Aouichaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Tounsi"> Mohamed Tounsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ines%20Mrizak"> Ines Mrizak</a>, <a href="https://publications.waset.org/abstracts/search?q=Zouhair%20Tabka"> Zouhair Tabka</a>, <a href="https://publications.waset.org/abstracts/search?q=Yassine%20Trabelsi"> Yassine Trabelsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to provide percentile values for vertical jumping performances and anthropometric characteristics for athletic Tunisian children. One thousand and fifty-five athletic Tunisian children and adolescents (643 boys and 412 girls) aged 7-18 years were randomly selected to participate in our study. They were asked to perform squat jumps and countermovement jumps. For each measurement, a least square regression model with high order polynomials was fitted to predict mean and standard deviation of vertical jumping parameters and anthropometric variables. Smoothed percentile curves and percentile values for the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles are presented for boys and girls. In conclusion, percentiles values of vertical jumping performances and anthropometric characteristics are provided. The new Tunisian reference charts obtained can be used as a screening tool to determine growth disorders and to estimate the proportion of adolescents with high or low muscular strength levels. This study may help in verifying the effectiveness of a specific training program and detecting highly talented athletes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=percentile%20values" title="percentile values">percentile values</a>, <a href="https://publications.waset.org/abstracts/search?q=jump%20height" title=" jump height"> jump height</a>, <a href="https://publications.waset.org/abstracts/search?q=leg%20muscle%20power" title=" leg muscle power"> leg muscle power</a>, <a href="https://publications.waset.org/abstracts/search?q=athletes" title=" athletes"> athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title=" anthropometry"> anthropometry</a> </p> <a href="https://publications.waset.org/abstracts/52019/percentile-reference-values-of-vertical-jumping-performances-and-anthropometric-characteristics-in-athletic-tunisian-children-and-adolescents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52019.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">428</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3888</span> A Mathematical Equation to Calculate Stock Price of Different Growth Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weiping%20Liu">Weiping Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an equation to calculate stock prices of different growth model.

Using institutional theory to classify coercive, normative, and mimetic pressures, as well as emerging drivers and barriers, this study explores the institutional factors influencing sustainable purchasing practices and the specific barriers faced by Tunisian SMEs in this area. An exploratory, abductive qualitative research design was adopted for this multiple case study, which involved 19 semi-structured interviews with owners and managers of 17 Tunisian manufacturing SMEs. The Gioia method was used to analyze the data, thus enabling the identification of key themes and relationships directly from the raw data. This approach facilitated a structured interpretation of the institutional factors influencing sustainable purchasing practices, with insights drawn from the participants' perspectives. The study reveals that Tunisian SMEs are at different levels of sustainability maturity, with a significant impact on their procurement practices. SMEs with advanced sustainability maturity integrate both environmental and social criteria into their supplier selection processes, while those with lower maturity levels rely on mostly traditional criteria such as cost, quality, and delivery. Key institutional drivers identified include regulatory pressure, market expectations, and stakeholder influence. Additional emerging drivers—such as certifications and standards, economic incentives, environmental commitment as a core value, and group-wide strategic alignment—also play a critical role in driving sustainable procurement. Conversely, the study reveals significant barriers, including economic constraints, limited awareness, and resource limitations. It also identifies three main categories of emerging barriers: (1) logistical and supply chain constraints, including retailer/intermediary dependency, tariff regulations, and a perceived lack of direct responsibility in B2B supply chains; (2) economic and financial constraints; and (3) operational barriers, such as unilateral environmental responsibility, a product-centric focus and the influence of personal relationships. Providing valuable insights into the role of sustainability maturity in supplier selection, this study is the first to explore sustainable procurement practices in the Tunisian SME context. Integrating an analysis of institutional drivers, including emerging incentives and barriers, provides practical implications for SMEs seeking to improve sustainability in procurement. The results highlight the need for stronger regulatory frameworks and support mechanisms to facilitate the adoption of sustainable practices among SMEs in Tunisia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tunisian%20SME" title="Tunisian SME">Tunisian SME</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20supplier%20selection" title=" sustainable supplier selection"> sustainable supplier selection</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20theory" title=" institutional theory"> institutional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=determinant" title=" determinant"> determinant</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20study" title=" qualitative study"> qualitative study</a> </p> <a href="https://publications.waset.org/abstracts/193204/determinants-of-sustainable-supplier-selection-an-exploratory-study-of-manufacturing-tunisians-smes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193204.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">10</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3886</span> Nexus of Pakistan Stock Exchange with World's Top Five Stock Markets after Launching China Pakistan Economic Corridor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Rauf">Abdul Rauf</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoxing%20Liu"> Xiaoxing Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Waqas%20Amin"> Waqas Amin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stock markets are fascinating more and more conductive to each other due to liberalization and globalization trends in recent years. China Pakistan Economic Corridor (CPEC) has dragged Pakistan stock exchange to the new heights and global investors are making investments to reap its benefits. So, in investors and government perspective, the study focuses co-integration of Pakistan stock exchange with world’s five big economies i-e US, China, England, Japan, and France. The time period of study is seven years i-e 2010 to 2016 and daily values of major indices of corresponding stock exchanges collected. All variables of that particular study are stationary at first difference confirmed by unit root test. The study Johansen system co integration test for analysis of data along with Granger causality test is performed for result purpose. Co integration test asserted that Pakistan stock exchange integrated with Shanghai stock exchange (SSE) and NIKKEI stock exchange in short run. Granger causality test also proclaimed these results. But NASDAQ, FTSE, DAX not co integrated and Granger cause at a short run but long run these markets are bonded with Pakistan stock exchange (KSE). VECM also confirmed this liaison in short and long run. Investors, therefore, need to be updated regarding co-integration of world’s stock exchanges to ensure well diversified and risk adjusted high returns. Equally, governments also need updated status so that they could reduce co-integration through multiple steps and hence drag investors for diversified investment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CPEC" title="CPEC">CPEC</a>, <a href="https://publications.waset.org/abstracts/search?q=DAX" title=" DAX"> DAX</a>, <a href="https://publications.waset.org/abstracts/search?q=FTSE" title=" FTSE"> FTSE</a>, <a href="https://publications.waset.org/abstracts/search?q=liberalization" title=" liberalization"> liberalization</a>, <a href="https://publications.waset.org/abstracts/search?q=NASDAQ" title=" NASDAQ"> NASDAQ</a>, <a href="https://publications.waset.org/abstracts/search?q=NIKKEI" title=" NIKKEI"> NIKKEI</a>, <a href="https://publications.waset.org/abstracts/search?q=SSE" title=" SSE"> SSE</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20markets" title=" stock markets"> stock markets</a> </p> <a href="https://publications.waset.org/abstracts/78053/nexus-of-pakistan-stock-exchange-with-worlds-top-five-stock-markets-after-launching-china-pakistan-economic-corridor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78053.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3885</span> Relationship between the Ability of Accruals and Non-Systematic Risk of Shares for Companies Listed in Stock Exchange: Case Study, Tehran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Najafian">Lina Najafian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Vakilifard"> Hamidreza Vakilifard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study focused on the relationship between the quality of accruals and non-systematic risk. The independent study variables included the ability of accruals, the information content of accruals, and amount of discretionary accruals considered as accruals quality measures. The dependent variable was non-systematic risk based on the Fama and French Three Factor model (FFTFM) and the capital asset pricing model (CAPM). The control variables were firm size, financial leverage, stock return, cash flow fluctuations, and book-to-market ratio. The data collection method was based on library research and document mining including financial statements. Multiple regression analysis was used to analyze the data. The study results showed that there is a significant direct relationship between financial leverage and discretionary accruals and non-systematic risk based on FFTFM and CAPM. There is also a significant direct relationship between the ability of accruals, information content of accruals, firm size, and stock return and non-systematic based on both models. It was also found that there is no relationship between book-to-market ratio and cash flow fluctuations and non-systematic risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accruals%20quality" title="accruals quality">accruals quality</a>, <a href="https://publications.waset.org/abstracts/search?q=non-systematic%20risk" title=" non-systematic risk"> non-systematic risk</a>, <a href="https://publications.waset.org/abstracts/search?q=CAPM" title=" CAPM"> CAPM</a>, <a href="https://publications.waset.org/abstracts/search?q=FFTFM" title=" FFTFM"> FFTFM</a> </p> <a href="https://publications.waset.org/abstracts/86210/relationship-between-the-ability-of-accruals-and-non-systematic-risk-of-shares-for-companies-listed-in-stock-exchange-case-study-tehran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86210.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3884</span> The Effect of Critical Audit Matters on Financial Information Quality: The Role of Audit Committee Expertise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khawla%20Hlel">Khawla Hlel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: This study aims to examine whether critical audit matters (CAM) affect financial information quality. We also investigate the moderating role of the audit committee on the association between CAM and financial information quality. Design/Methodology/Approach: The analysis is based on GLS and GMM regressions explaining the absolute value of discretionary accruals by using 52 Tunisian listed firms on the Tunisia Stock Exchange (TSE) for the period 2017-2020. Findings: We find evidence that managers react to the CAM by increasing the quality of financial disclosures. This study provides insights into how a change in the auditor’s report model might impact the quality of financial information. It suggests that external auditors and audit committees serve as a beneficial mechanism for enhancing financial information quality by reducing information asymmetry. In addition, our results indicate that CAM is an efficient monitoring mechanism that increases financial reporting quality and supervises managers. Originality: This study is important for potential investors who should assess CAM when evaluating firms. Furthermore, the authors expect the findings to be interesting to firms, as this study highlights the effectiveness of the auditor in reducing managerial opportunistic behavior and improving information quality. The results could encourage audit regulators to ameliorate the standards, as this research reinforces the role of the auditor in increasing the quality of financial disclosure by offering the required information for shareholders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20audit%20matters" title="critical audit matters">critical audit matters</a>, <a href="https://publications.waset.org/abstracts/search?q=audit%20committee" title=" audit committee"> audit committee</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20quality" title=" information quality"> information quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisian%20firms" title=" Tunisian firms"> Tunisian firms</a> </p> <a href="https://publications.waset.org/abstracts/150452/the-effect-of-critical-audit-matters-on-financial-information-quality-the-role-of-audit-committee-expertise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150452.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3883</span> Adopting English as a Language of Instruction of STEM in Tunisian Higher Education Institutions: Promises and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mimoun%20Melliti">Mimoun Melliti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper investigates the promises, challenges, and perspectives associated with teaching STEM subjects in English within Tunisian higher education institutions. The study explores the potential benefits of English-medium instruction in Science, Technology, Engineering, and Mathematics (henceforth STEM) education, with a special focus on enhanced global competitiveness, improved English language proficiency, and increased access to international resources and collaborations. Additionally, it examines the various challenges faced by educators and students, such as language shift/barriers, curriculum adaptation, faculty training, and student support. Through a comprehensive analysis of promises and challenges, this paper aims to provide insights and recommendations for effectively implementing English medium instruction (henceforth EMI) of STEM in Tunisian higher education institutions. The paper concludes with a recommended action plan for the proper introduction of EMI of STEM in Tunisia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EMI%3B" title="EMI;">EMI;</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM%20education" title=" STEM education"> STEM education</a>, <a href="https://publications.waset.org/abstracts/search?q=EFL" title=" EFL"> EFL</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20reforms" title=" language reforms"> language reforms</a> </p> <a href="https://publications.waset.org/abstracts/178302/adopting-english-as-a-language-of-instruction-of-stem-in-tunisian-higher-education-institutions-promises-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178302.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3882</span> Bank, Stock Market Efficiency and Economic Growth: Lessons for ASEAN-5</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tan%20Swee%20Liang">Tan Swee Liang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper estimates bank and stock market efficiency associations with real per capita GDP growth by examining panel-data across three different regions using Panel-Corrected Standard Errors (PCSE) regression developed by Beck and Katz (1995). Data from five economies in ASEAN (Singapore, Malaysia, Thailand, Philippines, and Indonesia), five economies in Asia (Japan, China, Hong Kong SAR, South Korea, and India) and seven economies in OECD (Australia, Canada, Denmark, Norway, Sweden, United Kingdom U.K., and United States U.S.), between 1990 and 2017 are used. Empirical findings suggest one, for Asia-5 high bank net interest margin means greater bank profitability, hence spurring economic growth. Two, for OECD-7 low bank overhead costs (as a share of total assets) may reflect weak competition and weak investment in providing superior banking services, hence dampening economic growth. Three, stock market turnover ratio has negative association with OECD-7 economic growth, but a positive association with Asia-5, which suggest the relationship between liquidity and growth is ambiguous. Lastly, for ASEAN-5 high bank overhead costs (as a share of total assets) may suggest expenses have not been channelled efficiently to income generating activities. One practical implication of the findings is that policy makers should take necessary measures toward financial liberalisation policies that boost growth through the efficiency channel, so that funds are efficiently allocated through the financial system between financial and real sectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20development" title="financial development">financial development</a>, <a href="https://publications.waset.org/abstracts/search?q=banking%20system" title=" banking system"> banking system</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20markets" title=" capital markets"> capital markets</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a> </p> <a href="https://publications.waset.org/abstracts/145009/bank-stock-market-efficiency-and-economic-growth-lessons-for-asean-5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145009.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3881</span> Prevalence of Methylenetetrahydrofolate Reductase A1298C Variant in Tunisian Childhood Acute Lymphoblastic Leukemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rim%20Frikha">Rim Frikha</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Ben%20Jema"> Maha Ben Jema</a>, <a href="https://publications.waset.org/abstracts/search?q=Moez%20Elloumi"> Moez Elloumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Rebai"> Tarek Rebai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Acute lymphoblastic leukemia (ALL); a common blood cancer characterized by the interaction between genetic and environmental factors. Methylenetetrahydrofolate reductase (MTHFR) is an essential folate metabolic enzyme in the processes of DNA synthesis and methylation. A common functional variant of the MTHFR gene, the A1298C, which induces disturbances in folate metabolism, may affect susceptibility to ALL. Objective: The present study aimed to assess the prevalence of MTHFR polymorphism A1298 > C in Tunisian children with ALL. Materials and Methods: A total of 28 Tunisian ALL children were enrolled in this study. Genomic DNA was extracted from whole venous blood collected in ethylenediaminetetraacetic acid (EDTA). Genotyping was carried out with restriction fragment length polymorphism (RFLP) using MboII restriction enzyme. Genotype distribution and allele frequency of MTHFR A1298C was calculated in ALL patients. Results: The A1298C variant of MTHFR was found in 11(19.6%) heterozygous and one homozygous patient (3.5%). Conclusions: This result highlights that A1298C polymorphism of MTHFR is common in Tunisian childhood ALL and suggests that this variant may have a potential role in leukemogenesis. Genotyping of large samples and different ethnicities are required to validate these findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methylenetetrahydrofolate%20reductase" title="methylenetetrahydrofolate reductase">methylenetetrahydrofolate reductase</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20lymphoblastic%20leukemia" title=" acute lymphoblastic leukemia"> acute lymphoblastic leukemia</a>, <a href="https://publications.waset.org/abstracts/search?q=A1298C%20variant" title=" A1298C variant"> A1298C variant</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a> </p> <a href="https://publications.waset.org/abstracts/121322/prevalence-of-methylenetetrahydrofolate-reductase-a1298c-variant-in-tunisian-childhood-acute-lymphoblastic-leukemia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3880</span> Stock Price Prediction with 'Earnings' Conference Call Sentiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sungzoon%20Cho">Sungzoon Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Jin%20Lee"> Hye Jin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungwhan%20Jeon"> Sungwhan Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongyoung%20Min"> Dongyoung Min</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungwon%20Lyu"> Sungwon Lyu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Major public corporations worldwide use conference calls to report their quarterly earnings. These 'earnings' conference calls allow for questions from stock analysts. We investigated if it is possible to identify sentiment from the call script and use it to predict stock price movement. We analyzed call scripts from six companies, two each from Korea, China and Indonesia during six years 2011Q1 – 2017Q2. Random forest with Frequency-based sentiment scores using Loughran MacDonald Dictionary did better than control model with only financial indicators. When the stock prices went up 20 days from earnings release, our model predicted correctly 77% of time. When the model predicted 'up,' actual stock prices went up 65% of time. This preliminary result encourages us to investigate advanced sentiment scoring methodologies such as topic modeling, auto-encoder, and word2vec variants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earnings%20call%20script" title="earnings call script">earnings call script</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a>, <a href="https://publications.waset.org/abstracts/search?q=sentiment%20analysis" title=" sentiment analysis"> sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20price%20prediction" title=" stock price prediction"> stock price prediction</a> </p> <a href="https://publications.waset.org/abstracts/86655/stock-price-prediction-with-earnings-conference-call-sentiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86655.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3879</span> Market Index Trend Prediction using Deep Learning and Risk Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shervin%20Alaei">Shervin Alaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Moradi"> Reza Moradi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trading in financial markets is subject to risks due to their high volatilities.

Empirical results reveal that dynamic conditional correlations switch between positive and negative values over the period under study. This correlation is negative during the major financial crises suggesting that gold can act as a safe haven during the major stress period of stock markets.

In the Tunisian context, ILP instruction remains less explored for academics and educational practitioners. In our experience as teachers, both at secondary school and at university levels, the instruction and assessment of pragmatics seem to be contentious. This paper firstly introduces the theoretical models of Interlanguage pragmatics Instruction and focuses on their implications for foreign language teaching. This study builds on the work of Ben Abdallah (2015) that investigated the effects of pragmatic Instruction on Tunisian EFL Learners where pragmatic Instruction has been approached from the perspective of students and their learning strategies. The data for the present study, however, come from Tunisian EFL teachers by investigating their pragmatics practices and their perceptions of pragmatic instruction. The findings indicated that EFL teachers have pragmatic awareness; yet, their reflections revealed that their awareness was mostly on theoretical pragmatic knowledge, and not explicitly brought into practical pragmatic applications. The paper concludes by promoting pragmatics instruction with the suggestion that EFL teachers should teach pragmatics in class. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interlanguage%20pragmatics%20theory" title="interlanguage pragmatics theory">interlanguage pragmatics theory</a>, <a href="https://publications.waset.org/abstracts/search?q=pragmatics" title=" pragmatics"> pragmatics</a>, <a href="https://publications.waset.org/abstracts/search?q=pragmatic%20instruction" title=" pragmatic instruction"> pragmatic instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=SLA" title=" SLA"> SLA</a> </p> <a href="https://publications.waset.org/abstracts/93437/interlanguage-pragmatics-instruction-evidence-from-efl-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93437.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">281</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3876</span> Investors' Ratio Analysis and the Profitability of Listed Firms: Evidence from Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abisola%20Akinola">Abisola Akinola</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinsulere%20Femi"> Akinsulere Femi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stock market has continually been a source of economic development in most developing countries.

The results from the analysis show that investors’ ratio analysis, when measured by earnings per share, have a positive and significant impact on profitability. However, the study noted that investors’ ratio analysis, when measured by dividend per share, tend to have a positive impact on profitability but it is statistically insignificant.

The project is founded by the European Commission as it involves four European partners - IULM University, Tampere University, University of Barcelona, and the Mediterranean network Unimed - and three Tunisian Universities – IPSI La Manouba, Sfax and Sousse – along with the Tunisian Ministry for Higher Education and the National Syndicate of Journalists. The focus on Tunisian condition is basically due to the role played by digital activists in its recent history. The research is dedicated to the relationship between political participation, news-making practices and the spread of social media, as it is affecting Tunisian society. As we know, Tunisia during the Arab Spring had been widely considered as a laboratory for the analysis the use of new technologies for political participation. Nonetheless, the literature about the Arab Spring actually fell short in explaining the genesis of the phenomenon, on the one hand by isolating technologies as a casual factor in the spread of demonstrations, and on the other by analyzing North-African condition through a biased perspective. Nowadays, it is interesting to focus on the consolidation of the information environment three years after the uprisings. And what is relevant, only a close, in-depth analysis of Tunisian society is able to provide an explanation of its history, and namely of the part of digital media in the overall evolution of political system. That is why the research is based on different methodologies: desk stage, interviews, and in-depth analysis of communication practices. Networked journalism is the condition determined by the technological innovation on news-making activities: a condition upon which professional journalist can no longer be considered the only player in the information arena, and a new skill must be developed. Along with democratization, nonetheless, the so-called citizen journalism is also likely to produce some ambiguous effects, such as the lack of professional standards and the spread of information cascades, which may prove to be particularly dangerous in an evolving media market as the Tunisian one. This is why, according to the project, a new profile must be defined, which is able to manage this new condition, and which can be hardly reduced to the parameters of traditional journalistic work. Rather than simply using new devices for news visualization, communication professionals must also be able to dialogue with all new players and to accept the decentralized nature of digital environments. This networked nature of news-making seemed to emerge during the Tunisian revolution, when bloggers, journalists, and activists used to retweet each other. Nonetheless, this intensification of communication exchange was inspired by the political climax of the uprising, while all media, by definition, are also supposed to bring some effects on people’s state of mind, culture and daily life routines. That is why it is worth analyzing the consolidation of these practices in a normal, post-revolutionary situation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-media" title="cross-media">cross-media</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=Mediterranean" title=" Mediterranean"> Mediterranean</a>, <a href="https://publications.waset.org/abstracts/search?q=networked%20journalism" title=" networked journalism"> networked journalism</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/42017/networked-media-citizen-journalism-and-political-participation-in-post-revolutionary-tunisia-insight-from-a-european-research-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42017.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3874</span> ChatGPT as a “Foreign Language Teacher”: Attitudes of Tunisian English Language Learners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Najeh%20Bel%27Kiry">Leila Najeh Bel'Kiry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial intelligence (AI) brought about many language robots, with ChatGPT being the most sophisticated thanks to its human-like linguistic capabilities. This aspect raises the idea of using ChatGPT in learning foreign languages. Starting from the premise that positions ChatGPT as a mediator between the language and the leaner, functioning as a “ghost teacher" offering a peaceful and secure learning space, this study aims to explore the attitudes of Tunisian students of English towards ChatGPT as a “Foreign Language Teacher” . Forty-five students, in their third year of fundamental English at Tunisian universities and high institutes, completed a Likert scale questionnaire consisting of thirty-two items and covering various aspects of language (phonology, morphology, syntax, semantics, and pragmatics). A scale ranging from 'Strongly Disagree,' 'Disagree,' 'Undecided,' 'Agree,' to 'Strongly Agree.' is used to assess the attitudes of the participants towards the integration of ChaGPTin learning a foreign language. Results indicate generally positive attitudes towards the reliance on ChatGPT in learning foreign languages, particularly some compounds of language like syntax, phonology, and morphology. However, learners show insecurity towards ChatGPT when it comes to pragmatics and semantics, where the artificial model may fail when dealing with deeper contextual and nuanced language levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20language%20model" title="artificial language model">artificial language model</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes" title=" attitudes"> attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20language%20learning" title=" foreign language learning"> foreign language learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ChatGPT" title=" ChatGPT"> ChatGPT</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20capabilities" title=" linguistic capabilities"> linguistic capabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisian%20English%20language%20learners" title=" Tunisian English language learners"> Tunisian English language learners</a> </p> <a href="https://publications.waset.org/abstracts/183529/chatgpt-as-a-foreign-language-teacher-attitudes-of-tunisian-english-language-learners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183529.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3873</span> Performance of Shariah-Based Investment: Evidence from Pakistani Listed Firms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsin%20Sadaqat">Mohsin Sadaqat</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilal%20Anwar%20Butt"> Hilal Anwar Butt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following the stock selection guidelines provided by the Sharia Board (SB), we segregate the firms listed at Pakistan Stock Exchange (PSX) into Sharia Compliant (SC) and Non-Sharia Compliant (NSC) stocks. Subsequently, we form portfolios within each group based on market capitalization and volatility. The purpose is to analyze and compare the performance of these two groups as the SC stocks have lesser diversification opportunities due to SB restrictions. Using data ranging from January 2004 until June 2016, our results indicate that in most of the cases the risk-adjusted returns (alphas) for the returns differential between SC and NCS firms are positive. In addition, the SC firms in comparison to their counterparts in PSX provides excess returns that are hedged against the market, size, and value-based systematic risks factors. Overall, these results reconcile with one prevailing notion that the SC stocks that have lower financial leverage and higher investment in real assets are lesser exposed to market-based risks. Further, the SC firms that are more capitalized and less volatile, perform better than lower capitalized and higher volatile SC and NSC firms. To sum up our results, we do not find any substantial evidence for opportunity loss due to limited diversification opportunities in case of SC firms. To optimally utilize scarce resources, investors should consider SC firms as a candidate in portfolio construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diversification" title="diversification">diversification</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=sharia%20compliant%20stocks" title=" sharia compliant stocks"> sharia compliant stocks</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20adjusted%20returns" title=" risk adjusted returns"> risk adjusted returns</a> </p> <a href="https://publications.waset.org/abstracts/85535/performance-of-shariah-based-investment-evidence-from-pakistani-listed-firms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85535.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3872</span> Executive Stock Options, Business Ethics and Financial Reporting Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philemon%20Rakoto">Philemon Rakoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper tests the improvement of financial reporting quality when firms award stock options to their executives.

This study seeks to examine empirically the extent of IT governance implementation within the firms listed on the Egyptian stock exchange (EGX30) and its determinants. Accordingly, 18 semi-structured interviews face to face, phone, and video-conferencing interviews using various tools (e.g., WebEx, Zoom, and Microsoft Teams) were undertaken at the interviewees’ offices in Egypt between the end of November 2019 and the end of August 2020. Results suggest that there are variances in the extent of IT Governance (ITG) implementation within the firms listed on the Egyptian stock exchange (EGX30), mainly caused by the industry type and internal and external triggers. The results also suggest that the organization size, the type of auditor, the criticality of the industry, the effective processes & KPIs, and the information intensity expertise of the CIO have a significant impact on IT governance implementation within the firms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effective%20IT%20governance" title="effective IT governance">effective IT governance</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20market" title=" Egyptian market"> Egyptian market</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security" title=" information security"> information security</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20controls" title=" risk controls"> risk controls</a> </p> <a href="https://publications.waset.org/abstracts/155186/information-technology-governance-implementation-and-its-determinants-in-the-egyptian-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155186.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3870</span> A Network Approach to Analyzing Financial Markets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Seedat">Yusuf Seedat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The necessity to understand global financial markets has increased following the unfortunate spread of the recent financial crisis around the world. Financial markets are considered to be complex systems consisting of highly volatile move-ments whose indexes fluctuate without any clear pattern. Analytic methods of stock prices have been proposed in which financial markets are modeled using common network analysis tools and methods. It has been found that two key components of social network analysis are relevant to modeling financial markets, allowing us to forecast accurate predictions of stock prices within the financial market. Financial markets have a number of interacting components, leading to complex behavioral patterns. This paper describes a social network approach to analyzing financial markets as a viable approach to studying the way complex stock markets function. We also look at how social network analysis techniques and metrics are used to gauge an understanding of the evolution of financial markets as well as how community detection can be used to qualify and quantify in-fluence within a network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20analysis" title="network analysis">network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks" title=" social networks"> social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20markets" title=" financial markets"> financial markets</a>, <a href="https://publications.waset.org/abstracts/search?q=stocks" title=" stocks"> stocks</a>, <a href="https://publications.waset.org/abstracts/search?q=nodes" title=" nodes"> nodes</a>, <a href="https://publications.waset.org/abstracts/search?q=edges" title=" edges"> edges</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20networks" title=" complex networks"> complex networks</a> </p> <a href="https://publications.waset.org/abstracts/142621/a-network-approach-to-analyzing-financial-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142621.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3869</span> Detecting Earnings Management via Statistical and Neural Networks Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Namazi">Mohammad Namazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Sadeghzadeh%20Maharluie"> Mohammad Sadeghzadeh Maharluie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Predicting earnings management is vital for the capital market participants, financial analysts and managers. The aim of this research is attempting to respond to this query: Is there a significant difference between the regression model and neural networks’ models in predicting earnings management, and which one leads to a superior prediction of it? In approaching this question, a Linear Regression (LR) model was compared with two neural networks including Multi-Layer Perceptron (MLP), and Generalized Regression Neural Network (GRNN). The population of this study includes 94 listed companies in Tehran Stock Exchange (TSE) market from 2003 to 2011. After the results of all models were acquired, ANOVA was exerted to test the hypotheses. In general, the summary of statistical results showed that the precision of GRNN did not exhibit a significant difference in comparison with MLP. In addition, the mean square error of the MLP and GRNN showed a significant difference with the multi variable LR model. These findings support the notion of nonlinear behavior of the earnings management. Therefore, it is more appropriate for capital market participants to analyze earnings management based upon neural networks techniques, and not to adopt linear regression models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earnings%20management" title="earnings management">earnings management</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20linear%20regression" title=" generalized linear regression"> generalized linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks%20multi-layer%20perceptron" title=" neural networks multi-layer perceptron"> neural networks multi-layer perceptron</a>, <a href="https://publications.waset.org/abstracts/search?q=Tehran%20stock%20exchange" title=" Tehran stock exchange"> Tehran stock exchange</a> </p> <a href="https://publications.waset.org/abstracts/29730/detecting-earnings-management-via-statistical-and-neural-networks-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29730.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">421</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3868</span> Volatility Spillover Among the Stock Markets of South Asian Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Aziz">Tariq Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Kumar"> Suresh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikesh%20Kumar"> Vikesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheraz%20Mustafa"> Sheraz Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhanzeb%20Marwat"> Jhanzeb Marwat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper provides an updated version of volatility spillover among the equity markets of South Asian countries, including Pakistan, India, Srilanka, and Bangladesh. The analysis uses both symmetric and asymmetric Generalized Autoregressive Conditional Heteroscedasticity models to investigate volatility persistence and leverage effect. The bivariate EGARCH model is used to test for volatility transmission between two equity markets. Weekly data for the period February 2013 to August 2019 is used for empirical analysis. The findings indicate that the leverage effect exists in the equity markets of all the countries except Bangladesh. The volatility spillover from the equity market of Bangladesh to all other countries is negative and significant whereas the volatility of the equity market of Sri-Lanka does influence the volatility of any other country’s equity market. Indian equity market influence only the volatility of the Sri-Lankan equity market; and there is bidirectional volatility spillover between the equity markets of Pakistan and Bangladesh.

Traditionally, trading in the stock market was done by professionals with years of training who understood patterns and exploited market opportunities in order to gain a profit. However, nowadays a larger portion of market participants are at minimum aided by market-data processing bots, which can generally generate more stable signals than the average human trader. The rise in trading bot usage can be accredited to the inherent advantages that bots have over humans in terms of processing large amounts of data, lack of emotions of fear or greed, and predicting market prices using past data and artificial intelligence, hence a growing number of approaches have been brought forward to tackle this task. However, the general limitation of these approaches can still be broken down to the fact that limited historical data doesn’t always determine the future, and that a lot of market participants are still human emotion-driven traders. Moreover, developing markets such as those of the cryptocurrency space have even less historical data to interpret than most other well-established markets. Due to this, some human traders have gone back to the tried-and-tested traditional technical analysis tools for exploiting market patterns and simplifying the broader spectrum of data that is involved in making market predictions. This paper proposes a method which uses neuro evolution techniques on both sentimental data and, the more traditionally human-consumed, technical analysis data in order to gain a more accurate forecast of future market behavior and account for the way both automated bots and human traders affect the market prices of Bitcoin and other cryptocurrencies. This study’s approach uses evolutionary algorithms to automatically develop increasingly improved populations of bots which, by using the latest inflows of market analysis and sentimental data, evolve to efficiently predict future market price movements. The effectiveness of the approach is validated by testing the system in a simulated historical trading scenario, a real Bitcoin market live trading scenario, and testing its robustness in other cryptocurrency and stock market scenarios. Experimental results during a 30-day period show that this method outperformed the buy and hold strategy by over 260% in terms of net profits, even when taking into consideration standard trading fees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuro-evolution" title="neuro-evolution">neuro-evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=Bitcoin" title=" Bitcoin"> Bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=trading%20bots" title=" trading bots"> trading bots</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20analysis" title=" technical analysis"> technical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=evolutionary%20algorithms" title=" evolutionary algorithms"> evolutionary algorithms</a> </p> <a href="https://publications.waset.org/abstracts/136305/evotrader-bitcoin-trading-using-evolutionary-algorithms-on-technical-analysis-and-social-sentiment-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3865</span> Dynamic Comovements between Exchange Rates, Stock Prices and Oil Prices: Evidence from Developed and Emerging Latin American Markets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nini%20Johana%20Marin%20Rodriguez">Nini Johana Marin Rodriguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper applies DCC, EWMA and OGARCH models to compare the dynamic correlations between exchange rates, oil prices, exchange rates and stock markets to examine the time-varying conditional correlations to the daily oil prices and index returns in relation to the US dollar/local currency for developed (Canada and Mexico) and emerging Latin American markets (Brazil, Chile, Colombia and Peru). Changes in correlation interactions are indicative of structural changes in market linkages with implications to contagion and interdependence. For each pair of stock price-exchange rate and oil price-US dollar/local currency, empirical evidence confirms of a strengthening negative correlation in the last decade. Methodologies suggest only two events have significatively impact in the countries analyzed: global financial crisis and Europe crisis, both events are associated with shifts of correlations to stronger negative level for most of the pairs analyzed. While, the first event has a shifting effect on mainly emerging members, the latter affects developed members. The identification of these relationships provides benefits in risk diversification and inflation targeting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crude%20oil" title="crude oil">crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20conditional%20correlation" title=" dynamic conditional correlation"> dynamic conditional correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20rates" title=" exchange rates"> exchange rates</a>, <a href="https://publications.waset.org/abstracts/search?q=interdependence" title=" interdependence"> interdependence</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20prices" title=" stock prices"> stock prices</a> </p> <a href="https://publications.waset.org/abstracts/67128/dynamic-comovements-between-exchange-rates-stock-prices-and-oil-prices-evidence-from-developed-and-emerging-latin-american-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67128.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3864</span> Synthesis of Biolubricant Base Stock from Palm Methyl Ester</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Sulihatimarsyila%20Abd%20Wafti">Nur Sulihatimarsyila Abd Wafti</a>, <a href="https://publications.waset.org/abstracts/search?q=Harrison%20Lik%20Nang%20Lau"> Harrison Lik Nang Lau</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabilah%20Kamaliah%20Mustaffa"> Nabilah Kamaliah Mustaffa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Azreena%20Idris"> Nur Azreena Idris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of biolubricant has gained its popularity over the last decade. Base stock produced using methyl ester and trimethylolethane (TME) can be potentially used for biolubricant production due to its biodegradability, non-toxicity and good thermal stability. The synthesis of biolubricant base stock e.g. triester (TE) via transesterification of palm methyl ester and TME in the presence of sodium methoxide as the catalyst was conducted. Factors influencing the reaction conditions were investigated including reaction time, temperature and pressure. The palm-based biolubricant base stock produced was analysed for its monoester (ME), diester (DE) and TE contents using gas chromatography as well as its lubricating properties such as viscosity, viscosity index, oxidation stability, and density. The resulting base stock containing 90 wt% TE was successfully synthesized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biolubricant" title="biolubricant">biolubricant</a>, <a href="https://publications.waset.org/abstracts/search?q=methyl%20ester" title=" methyl ester"> methyl ester</a>, <a href="https://publications.waset.org/abstracts/search?q=triester%20transesterification" title=" triester transesterification"> triester transesterification</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricating%20properties" title=" lubricating properties"> lubricating properties</a> </p> <a href="https://publications.waset.org/abstracts/52775/synthesis-of-biolubricant-base-stock-from-palm-methyl-ester" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52775.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3863</span> Islamic Equity Markets Response to Volatility of Bitcoin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zakaria%20S.%20G.%20Hegazy">Zakaria S.

Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the dependence structure of Islamic stock markets on Bitcoin’s realized volatility components in bear, normal, and bull market periods. A quantile regression approach is employed, after adjusting raw returns with respect to a broad set of relevant global factors and accounting for structural breaks in the data. The results reveal that upside volatility tends to exert negative influences on Islamic developed-market returns more in bear than in bull market conditions, while downside volatility positively affects returns during bear and bull conditions. For emerging markets, we find that the upside (downside) component exerts lagged negative (positive) effects on returns in bear (all) market regimes. By and large, the dependence structures turn out to be asymmetric. Our evidence provides essential implications for investors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency%20markets" title="cryptocurrency markets">cryptocurrency markets</a>, <a href="https://publications.waset.org/abstracts/search?q=bitcoin" title=" bitcoin"> bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=realized%20volatility%20measures" title=" realized volatility measures"> realized volatility measures</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetry" title=" asymmetry"> asymmetry</a>, <a href="https://publications.waset.org/abstracts/search?q=quantile%20regression" title=" quantile regression"> quantile regression</a> </p> <a href="https://publications.waset.org/abstracts/141351/islamic-equity-markets-response-to-volatility-of-bitcoin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141351.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3862</span> Accounting Quality and The Adoption of IFRS: Evidence from China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaldoon%20G.%20Albitar">Khaldoon G.

This study investigates the impact of adopting IFRS on accounting quality for a sample of listed on Chinese companies during the period 2003-2013 with sample of 10846 observations over a four-year period before and a five-year period after the adoption of IFRS. This study tests whether the level of earnings management is significantly lower after the adoption of IFRS, and reported earnings is more value relevant during the IFRS period by using the Ohlson model and Jones model, as modified by Dechow. The empirical results show that accounting quality improved with lower earnings management and higher value relevant after the adoption of IFRS in China. The current study contributes to the literature on IFRS adoption and earning quality in two ways. First, As most of the existing studies on earnings quality and IFRS have been conducted on data from the U.S and European countries, this study fills a gap in the existing literature by studying the effect of adoption of IFRS on earnings quality in an emerging market. Second, the findings of our study have important implications for policymakers, auditors, multinational firms, and users of financial reports. As the rapid growth of China's economy gains global recognition, the Chinese stock market is capturing the attention of international investor. <p class="card-text"><strong>Keywords:</strong> <a
