For companies improving the quality of their products, reducing the cost and improving the speed of delivery makes them favorable to the client who feels like all their needs have been met. The research occurs between the months of January 2018 to April 2018 which is about four months. The research experiment design uses the pretest-posttest experimental design set up between two companies both using the traditional method of manufacturing with no technology. In one company technology is introduced while in the other company the process remains the same traditional method of production. Both companies analyze the results at the end of a four-month period before a conclusion is drawn from both the pretest and the final test. The experiment results show that technology improves quality of the product, improves the speed of delivery while at the same time reduce cost benefiting both the producer and the client. Technology should, therefore, be implemented in companies to give them an edge over the competition. With technology in companies, the United States can reclaim production from overseas companies that have taken over by providing cheap labor. Better satisfied customers mean more production which in turn means more jobs for the people in the United States. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology" title="technology">technology</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20product" title=" quality of product"> quality of product</a>, <a href="https://publications.waset.org/abstracts/search?q=speed%20up%20delivery" title=" speed up delivery"> speed up delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a> </p> <a href="https://publications.waset.org/abstracts/96151/impact-of-technology-on-product-quality-speed-up-delivery-and-cost" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96151.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">157</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">147</span> Girls' Underperformance in Science: From Biological Determinism and Feminist Perspectives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raza%20Ullah">Raza Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazir%20Ullah"> Hazir Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is ample evidence that reveals the outstanding performance of girls in a different range of subjects. However, it is pertinent to mention here that boys have historically dominated girls, particularly in math, physics, and technological subjects across the globe with the exception of few developed countries. This article examines the reasons why girls are underdog in STEM subjects. The article critically analyzes two main approaches towards gender and education: biological determinist and feminist. This article highlights that social factors influencing girls performance in STEM subjects have not analyzed critically, and girls underachieving in science has linked with biological and sex differences. The article concludes that the underperformance of girls in a STEM subject is the direct response of socio-cultural factors. Thus, socio-cultural factors are responsible for the dearth of girls in STEM subjects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=underperformance" title=" underperformance"> underperformance</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM" title=" STEM"> STEM</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=sex" title=" sex"> sex</a> </p> <a href="https://publications.waset.org/abstracts/112623/girls-underperformance-in-science-from-biological-determinism-and-feminist-perspectives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112623.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">162</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">146</span> Reliability of Dissimilar Metal Soldered Joint in Fabrication of Electromagnetic Interference Shielded Door Frame </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Waheed">Rehan Waheed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Aftab%20Saeed"> Hasan Aftab Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Wasim%20Tarar"> Wasim Tarar</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Mahmood"> Khalid Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajid%20Ullah%20Butt"> Sajid Ullah Butt </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electromagnetic Interference (EMI) shielded doors made from brass extruded channels need to be welded with shielded enclosures to attain optimum shielding performance. Control of welding induced distortion is a problem in welding dissimilar metals like steel and brass. In this research, soldering of the steel-brass joint has been proposed to avoid weld distortion. The material used for brass channel is UNS C36000. The thickness of brass is defined by the manufacturing process, i.e. extrusion. The thickness of shielded enclosure material (ASTM A36) can be varied to produce joint between the dissimilar metals. Steel sections of different gauges are soldered using (91% tin, 9% zinc) solder to the brass, and strength of joint is measured by standard test procedures. It is observed that thin steel sheets produce a stronger bond with brass. The steel sections further require to be welded with shielded enclosure steel sheets through TIG welding process. Stresses and deformation in the vicinity of soldered portion is calculated through FE simulation. Crack formation in soldered area is also studied through experimental work. It has been found that in thin sheets deformation produced due to applied force is localized and has no effect on soldered joint area whereas in thick sheets profound cracks have been observed in soldered joint. The shielding effectiveness of EMI shielded door is compromised due to these cracks. The shielding effectiveness of the specimens is tested and results are compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20metal" title="dissimilar metal">dissimilar metal</a>, <a href="https://publications.waset.org/abstracts/search?q=EMI%20shielding" title=" EMI shielding"> EMI shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20strength" title=" joint strength"> joint strength</a>, <a href="https://publications.waset.org/abstracts/search?q=soldering" title=" soldering"> soldering</a> </p> <a href="https://publications.waset.org/abstracts/94980/reliability-of-dissimilar-metal-soldered-joint-in-fabrication-of-electromagnetic-interference-shielded-door-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94980.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">163</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">145</span> DC-to-DC Converters for Low-Voltage High-Power Renewable Energy Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdar%20Ali">Abdar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Ullah"> Rizwan Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ullah"> Zahid Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on the study of DC-to-DC converters, which are suitable for low-voltage high-power applications. The output voltages generated by renewable energy sources such as photovoltaic arrays and fuel cell stacks are generally low and required to be increased to high voltage levels. Development of DC-to-DC converters, which provide high step-up voltage conversion ratios with high efficiencies and low voltage stresses is one of the main issues in the development of renewable energy systems. A procedure for three converters-conventional DC-to-DC converter, interleaved boost converter, and isolated flyback based converter, is illustrated for a given set of specifications.

The objectives of the present study were to provide the predictors for low Fractional flow reserve (FFR) at coronary artery (LCx) and the possible treatment strategies for the compromised LCx-together with their long term outcomes. Methods: A total of 563 included patients out of 1974 patients admitted to our hospital from February 2015 to November 2020 with significant distal LM-bifurcation lesions. The enrolled patients underwent single-stent cross-over PCI under IVUS guidance with further LCx intervention as indicated by measured FFR. Results: The included patients showed angiographic significant LCx ostial affection after LM-stenting, but only 116 (20.6%) patients had FFR <0.8. The 3-year composite MACE rates were comparable between the high and low FFR groups (16.8% vs. 15.5%, respectively; P=0.744). In a multivariable analysis, a low FFR in the LCx was associated with post-stenting MLA of the LCx (OR: 0.032, P <0.001), post-stenting LCx-plaque burden (OR: 1.166, P <0.001), post-stenting LM-MLA (OR: 0.821, P =0.038) and pre-stenting LCx-MLA (OR: 0.371, P =0.044). In patients with low FFR, management of compromised LCx with DEB had the lowest 3-year MACE rate (8.1%) as compared to either KBI (17.5%) or stenting group (20.5%), P =0.299. Conclusion: FFR-guided LCx intervention can avoid unnecessary LCx intervention. The post-stenting predictors of low FFR include post-stenting MLA and plaque burden of the LCx and MV stent length. The 3-year MACE rates were comparable between high FFR patients and patients who had low FFR and were adequately managed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractional%20flow%20reserve" title="fractional flow reserve">fractional flow reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=left%20main%20stem" title=" left main stem"> left main stem</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20coronary%20interventions" title=" percutaneous coronary interventions"> percutaneous coronary interventions</a>, <a href="https://publications.waset.org/abstracts/search?q=intravascular%20ultrasound" title=" intravascular ultrasound"> intravascular ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/185752/predictors-and-3-year-outcomes-of-compromised-left-circumflex-coronary-artery-after-left-main-crossover-stenting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185752.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">39</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">143</span> Zero Voltage Switched Full Bridge Converters for the Battery Charger of Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Ullah">Rizwan Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdar%20Ali"> Abdar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ullah"> Zahid Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper illustrates the study of three isolated zero voltage switched (ZVS) PWM full bridge (FB) converters to charge the high voltage battery in the charger of electric vehicle (EV). EV battery chargers have several challenges such as high efficiency, high reliability, low cost, isolation, and high power density. The cost of magnetic and filter components in the battery charger is reduced when switching frequency is increased. The increase in the switching frequency increases switching losses. ZVS is used to reduce switching losses and to operate the converter in the battery charger at high frequency. The performance of each of the three converters is evaluated on the basis of ZVS range, dead times of the switches, conduction losses of switches, circulating current stress, circulating energy, duty cycle loss, and efficiency. The limitations and merits of each PWM FB converter are reviewed. The converter with broader ZVS range, high efficiency and low switch stresses is selected for battery charger applications in EV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=PWM%20FB%20converter" title=" PWM FB converter"> PWM FB converter</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20voltage%20switching" title=" zero voltage switching"> zero voltage switching</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20energy" title=" circulating energy"> circulating energy</a> </p> <a href="https://publications.waset.org/abstracts/54708/zero-voltage-switched-full-bridge-converters-for-the-battery-charger-of-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54708.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">439</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">142</span> Information Technology Capabilities and Organizational Performance: Mediating Role of Strategic Benefits of It: A Comparison between China and Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Ullah">Rehan Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary purpose of the study is to observe the relationship that exists between the organizational information technology (IT) capabilities and the organizational performance in China and Pakistan. Nations like China and Pakistan utilize modern techno-how to enhance their production endeavors. Therefore, making a wide-ranging comparison of the manufacturing services between China and Pakistan was chosen due to numerous reasons. One reason for carrying out this comparison is to determine how IT of the two countries enhances organizational competency on small and medium-sized manufacturing enterprises (SMEs). The study hypothesized that organizational IT capabilities (IT infrastructure, IT competence) have a positive influence on organizational performance and the strategic benefits of IT have a mediating effect on the relationship between IT capability and organizational performance. To investigate the relationship between IT capabilities and organizational performance, surveys were sent to managers of small, medium-sized manufacturing organizations located in the southwestern region, Sichuan province of China, and Pakistani companies, which are located in Islamabad, Lahore, and Karachi. These cities were selected as typical representatives of each country. Organizational performance has been measured in terms of profitability, organizational success, growth, market share, and innovativeness. Out of 400 surveys distributed to different manufacturing organizations, 303 usable and valid responses were received that are analyzed in this research. The data were examined using SPSS and Smart PLS computer software. The results of the study, including the descriptive statistics of each variable, are used. The outer model has been measured with considerations to content validity, discriminant validity, and convergent validity. The path coefficients among the constructs were also computed when analyzing the structural model using the bootstrapping technique. The analysis of data from both China and Pakistan yields an identical but unique result. The results show that IT infrastructure, IT competence, strategic benefits of IT are all correlated to the performance of the organizations. Moreover, strategic benefits of IT have been proved to mediate the relationship between IT capabilities and organization performance. The author, concerning the role of IT on the performance of an organization, highlights the different aspects as well as its benefits in an organization. The overall study concludes several implications for both managers and academicians. It also provides the limitations of the study and offers recommendations for future studies and practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organizational%20performance" title="organizational performance">organizational performance</a>, <a href="https://publications.waset.org/abstracts/search?q=IT%20capabilities" title=" IT capabilities"> IT capabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=IT%20infrastructure" title=" IT infrastructure"> IT infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=IT%20competence" title=" IT competence"> IT competence</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20benefits%20of%20IT" title=" strategic benefits of IT"> strategic benefits of IT</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a> </p> <a href="https://publications.waset.org/abstracts/129641/information-technology-capabilities-and-organizational-performance-mediating-role-of-strategic-benefits-of-it-a-comparison-between-china-and-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129641.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">94</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">141</span> Green It-Outsourcing Assurance Model for It-Outsourcing Vendors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siffat%20%20Ullah%20Khan">Siffat Ullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahmat%20Ullah%20Khan"> Rahmat Ullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafiq%20%20Ahmad%20Khan"> Rafiq Ahmad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibullah%20Khan"> Habibullah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green IT or green computing has emerged as a fast growing business paradigm in recent years in order to develop energy-efficient Software and peripheral devices.

Amongst these motivators 7 were ranked as critical motivators. We also identified 21, in total, practices for addressing these critical motivators. Based on these inputs we have developed Green IT-Outsourcing Assurance Model (GITAM) for IT-Outsourcing vendors. The model comprises four different levels. i.e. Initial, White, Green and Grey. Each level comprises different critical motivators and their relevant practices. We conclude that our model, GITAM, will assist IT-Outsourcing vendors in gauging their level in order to manage IT-Outsourcing activities in a green and sustainable fashion to assist the environment and to reduce the carbon emission. The model will assist vendors in improving their current level by suggesting various practices. The model will contribute to the body of knowledge in the field of Green IT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Green%20IT-outsourcing%20Assurance%20Model%20%28GITAM%29" title="Green IT-outsourcing Assurance Model (GITAM)">Green IT-outsourcing Assurance Model (GITAM)</a>, <a href="https://publications.waset.org/abstracts/search?q=Systematic%20Literature%20Review" title=" Systematic Literature Review"> Systematic Literature Review</a>, <a href="https://publications.waset.org/abstracts/search?q=Empirical%20Study" title=" Empirical Study"> Empirical Study</a>, <a href="https://publications.waset.org/abstracts/search?q=Case%20Study" title=" Case Study"> Case Study</a> </p> <a href="https://publications.waset.org/abstracts/132174/green-it-outsourcing-assurance-model-for-it-outsourcing-vendors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132174.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">252</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">140</span> Television Commercial Ideation: Considerations for the Future</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashid%20Farooq">Rashid Farooq</a>, <a href="https://publications.waset.org/abstracts/search?q=Moazzam%20Naseer"> Moazzam Naseer</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Hasan"> Rehan Hasan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasing challenges posed to the creativity in the discipline of advertising during time’s movement towards the maturity of The Third Wave – a concept of change by Toffler, have to be the major theme of this study.

The climatic data used for research was acquired from Pakistan Meteorological Department (PMD) Islamabad, Agriculture Research Institute, Weather Station Peshawar and Tarnab Peshawar. Agro-climatic classes of each location were determined using three criteria mean temperature of the coldest month, mean temperature of the warmest month and aridity index. The agro-climatic classes of Dir, Swat, Kakul and Balakot were classified as Humid, Cold and very Warm (H-K-VW). Average aridity index of wheat for Dir, Swat, Kakul, and Balakot was 2.23, 2.67, 1.94 and 2.34 and for Maize was 1.31, 1.26, 1.97, and 2.83 respectively. The overall and decade-wise trend of GDD of Wheat and Maize was declined in Swat and Kakul while increased in Dir and Balakot.The average maximum CGI (1.26) and (0.73) of Wheat and Maize was observed for Balakot and Dir, while the minimum (1.09) and (0.62) was observed for Swat and Kakul. Spatio-temporal analysis of rainfall shows that the trend has increased in Swat while decreased in Dir, Kakul and Balakot. From the relation between rainfalls with altitude showed that there was an increasing trend between rainfalls with altitude. The maximum average rainfall was in Swat (2703mm) on altitude 2000m while the minimum average rainfall was observed in Kakul (1410mm) on altitude of 1255m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agro-climatic%20zones" title="agro-climatic zones">agro-climatic zones</a>, <a href="https://publications.waset.org/abstracts/search?q=aridity%20index" title=" aridity index"> aridity index</a>, <a href="https://publications.waset.org/abstracts/search?q=GDD" title=" GDD"> GDD</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfall" title=" rainfall"> rainfall</a> </p> <a href="https://publications.waset.org/abstracts/87732/agro-climatic-analysis-in-the-northern-areas-of-khyber-pakhtunkhwa-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87732.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">419</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">138</span> Information Literacy Skills of Legal Practitioners in Khyber Pakhtunkhwa-Pakistan: An Empirical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ullah%20Jan">Saeed Ullah Jan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaukat%20Ullah"> Shaukat Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose of the study: The main theme of this study is to explore the information literacy skills of the law practitioners in Khyber Pakhtunkhwa-Pakistan under the heading "Information Literacy Skills of Legal Practitioners in Khyber Pakhtunkhwa-Pakistan: An Empirical Study."

Although, it is important to assess the risk attitude of farmers and their perception towards different calamitous risk sources for better understanding of their risk management adoption decisions, to the best of our knowledge no studies have been carried out to analyze the risk attitude and risk perceptions in the context of tobacco production in Pakistan. Therefore the study in hand is conducted with an attempt to overcome the gap in existing literature by analyzing different catastrophic risk sources faced by tobacco growers, their attitude towards risk and the effect of socioeconomic and demographic characteristics, farmers’ participation in contract farming and off-farm diversification on their risk attitude and risk perception. Around 78% of Pakistan’s entire tobacco crop and nearly all of the country’s Flue-Cured Virginia (FCV) tobacco is produced in Khyber Pakhtunkhwa (KPK) province alone. The yield/hectare of tobacco produced in KPK province is 14% higher than the global average and 22 % higher than national average. Khyber Pakhtunkhwa province was selected as main study area as nearly all of the country’s Flue-Cured Virginia (FCV) tobacco is produced in Khyber Pakhtunkhwa (KPK) province alone. Six districts were purposely selected based on their contribution in overall production for the last five years which accounts for more than 94.84% of the tobacco production in KPK province. Specific objectives taken into considerations for this study are the risk attitude of the farmers for growing FCV tobacco crop, farmers’ risk perception for different risk sources related to tobacco production (as far as the incidence and severity of each risk source is concerned) and the effect of socioeconomic characteristics, contract farming participation and off-farm diversification (income) on the risk attitude and risk perception of FCV tobacco growers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20attitude" title="risk attitude">risk attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20perception" title=" risk perception"> risk perception</a>, <a href="https://publications.waset.org/abstracts/search?q=contract%20farming" title=" contract farming"> contract farming</a>, <a href="https://publications.waset.org/abstracts/search?q=off-farm%20diversification" title=" off-farm diversification"> off-farm diversification</a>, <a href="https://publications.waset.org/abstracts/search?q=probit%20model" title=" probit model"> probit model</a> </p> <a href="https://publications.waset.org/abstracts/74854/determinants-of-risk-perceptions-and-risk-attitude-among-flue-cured-virginia-tobacco-growers-a-case-study-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74854.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">362</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">135</span> Demographic Profile, Risk Factors and In-hospital Outcomes of Acute Coronary Syndrome (ACS) in Young Population, in Pakistan-Single Center Real World Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Qudrat">Asma Qudrat</a>, <a href="https://publications.waset.org/abstracts/search?q=Abid%20Ullah"> Abid Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafi%20Ullah"> Rafi Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Raza"> Ali Raza</a>, <a href="https://publications.waset.org/abstracts/search?q=Shah%20Zeb"> Shah Zeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Ali%20Shan%20Ul-Haq"> Syed Ali Shan Ul-Haq</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahkar%20Ahmed%20Shah"> Shahkar Ahmed Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Attiya%20Hameed%20Khan"> Attiya Hameed Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Zaheer"> Saad Zaheer</a>, <a href="https://publications.waset.org/abstracts/search?q=Umama%20Qasim"> Umama Qasim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiran%20Jamal"> Kiran Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahoor%20khan"> Zahoor khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Coronary artery disease (CAD) is the major public health issue associated with high mortality and morbidity rate worldwide. Young patients with ACS have unique characteristics with different demographic profiles and risk factors. The precise diagnosis and early risk stratification is important in guiding treatment and predicting the prognosis of young patients with ACS. To evaluate the associated demographics, risk factors, and outcomes profile of ACS in young age patients. Methods: The research follow a retrospective design, the single centre study of patients diagnosis with the first event of ACS in young age (>18 and <40) were included. Data collection included demographic profiles, risk factors, and in-hospital outcomes of young ACS patients. The patient’s data was retrieved through Electronic Medical Records (EMR) of Peshawar Institute of Cardiology (PIC), and all characteristic were assessed. Results: In this study, 77% were male, and 23% were female patients. The risk factors were assessed with CAD and shown significant results (P < 0.01). The most common presentation was STEMI, with (45%) most in ACS young patients. The angiographic pattern showed single vessel disease (SVD) in 49%, double vessel disease (DVD) in 17% and triple vessel disease (TVD) was found in 10%, and Left Artery Disease (LAD) (54%) was present to be the most common involved artery. Conclusion: It is concluded that the male sex was predominant in ACS young age patients. SVD was the common coronary angiographic ﬁnding.

Shale gas has emerged as an important unconventional vigor resource, necessitating innovative techniques to enhance its extraction. The key objective of this study is to examine the influence of fracture parameters on reservoir productivity and formulate strategies for production optimization. A sophisticated model integrating gas flow dynamics and real stress considerations is developed for hydraulic fracturing in multi-stage shale gas reservoirs. This model encompasses distinct zones: a single-porosity medium region, a dual-porosity average region, and a hydraulic fracture region. The apparent permeability of the matrix and fracture system is modeled using principles like effective stress mechanics, porous elastic medium theory, fractal dimension evolution, and fluid transport apparatuses. The developed model is then validated using field data from the Barnett and Marcellus formations, enhancing its reliability and accuracy. By solving the partial differential equation by means of COMSOL software, the research yields valuable insights into optimal fracture parameters. The findings reveal the influence of fracture length, diversion capacity, and width on gas production. For reservoirs with higher permeability, extending hydraulic fracture lengths proves beneficial, while complex fracture geometries offer potential for low-permeability reservoirs. Overall, this study contributes to a deeper understanding of hydraulic cracking dynamics in shale gas reservoirs and provides essential guidance for optimizing gas production. The research findings are instrumental for energy industry professionals, researchers, and policymakers alike, shaping the future of sustainable energy extraction from unconventional resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid-solid%20coupling" title="fluid-solid coupling">fluid-solid coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=apparent%20permeability" title=" apparent permeability"> apparent permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20gas%20reservoir" title=" shale gas reservoir"> shale gas reservoir</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20property" title=" fracture property"> fracture property</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/175223/optimization-of-shale-gas-production-by-advanced-hydraulic-fracturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175223.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">71</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">133</span> Analytical Solutions for Corotational Maxwell Model Fluid Arising in Wire Coating inside a Canonical Die </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sohail%20Khan">Muhammad Sohail Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Ali%20Shah"> Rehan Ali Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper applies the optimal homotopy perturbation method (OHPM) and the optimal homotopy asymptotic method (OHAM) introduced recently to obtain analytic approximations of the non-linear equations modeling the flow of polymer in case of wire coating of a corotational Maxwell fluid.

This study was designed to investigate the vegetation structure and species diversity along with the environmental variables in the Yakhtangay hill district Shangla of the Himalayan Mountain series Pakistan by using multivariate statistical analysis. Quadrat’s method was used and a total of 171 Quadrats were laid down 57 for Tree, Shrubs and Herbs, respectively, to analyze the phytosociological attributes of the vegetation. The vegetation of the selected area was classified into different Life and leaf-forms according to Raunkiaer classification, while PCORD software version 5 was used to classify the vegetation into different plants communities by Two-way indicator species Analysis (TWINSPAN). The CANOCCO version 4.5 was used for DCA and CCA analysis to find out variation directories of vegetation with different environmental variables. A total of 114 plants species belonging to 45 different families was investigated inside the area. The Rosaceae (12 species) was the dominant family followed by Poaceae (10 species) and then Asteraceae (7 species). Monocots were more dominant than Dicots and Angiosperms were more dominant than Gymnosperms. Among the life forms the Hemicryptophytes and Nanophanerophytes were dominant, followed by Therophytes, while among the leaf forms Microphylls were dominant, followed by Leptophylls. It is concluded that among the edaphic factors such as soil pH, the concentration of soil organic matter, Calcium Carbonates concentration in soil, soil EC, soil TDS, and physiographic factors such as Altitude and slope are affecting the structure of vegetation, species composition and species diversity at the significant level with p-value ≤0.05. The Vegetation of the selected area was classified into four major plants communities and the indicator species for each community was recorded. Classification of plants into 4 different communities based upon edaphic gradients favors the individualistic hypothesis. Indicator Species Analysis (ISA) shows the indicators of the study area are mostly indicators to the Himalayan or moist temperate ecosystem, furthermore, these indicators could be considered for micro-habitat conservation and respective ecosystem management plans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=species%20richness" title="species richness">species richness</a>, <a href="https://publications.waset.org/abstracts/search?q=edaphic%20gradients" title=" edaphic gradients"> edaphic gradients</a>, <a href="https://publications.waset.org/abstracts/search?q=canonical%20correspondence%20analysis%20%28CCA%29" title=" canonical correspondence analysis (CCA)"> canonical correspondence analysis (CCA)</a>, <a href="https://publications.waset.org/abstracts/search?q=TWCA" title=" TWCA"> TWCA</a> </p> <a href="https://publications.waset.org/abstracts/149820/vegetation-assessment-under-the-influence-of-environmental-variables-a-case-study-from-the-yakhtangay-hill-of-himalayan-range-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149820.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">152</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">129</span> Innovative Textile Design Using in-situ Ag NPs incorporation into Natural Fabric Matrix</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Rehan">M.

Ag NPs as a coloration and antimicrobial agent were prepared in situ incorporation into fabric matrix (Cotton and Wool) by using trisodium citrate as reducing and stabilizing agent. The Ag NPs treated fabric (Cotton and Wool) showed different color because of localized surface Plasmon resonance (LSPR) property of Ag NPs. The formation of Ag NPs was confirmed by UV/Vis spectra for the supernatant solutions and The Ag NPs treated fabric (Cotton and Wool) were characterized by scanning electron microscopy (SEM) and X-ray photo electron spectroscopy (XPS). The dependence of color properties characterized by colorimetric, fastness and antibacterial properties evaluated by Escherichia coli using counting method and the reaction parameters were studied. The results indicate that, the in situ Ag NPs incorporation into fabric matrix approach can simultaneously impart colorant and antimicrobial properties into different fabric substrates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ag%20NPs" title="Ag NPs">Ag NPs</a>, <a href="https://publications.waset.org/abstracts/search?q=coloration" title=" coloration"> coloration</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=wool" title=" wool"> wool</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton%20fabric" title=" cotton fabric"> cotton fabric</a> </p> <a href="https://publications.waset.org/abstracts/11113/innovative-textile-design-using-in-situ-ag-nps-incorporation-into-natural-fabric-matrix" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11113.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">357</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">128</span> Information Needs and Seeking Behaviour of Postgraduate Students of Kohat University of Science and Technology, Khyber Pakhtunkhwa, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ullah%20Jan">Saeed Ullah Jan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali"> Muhammad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Misbah%20Ullah%20Awan"> Misbah Ullah Awan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: This study investigated the information needs and seeking behaviour, and hurdles to information seeking of Post Graduate students of Kohat University of Science and Technology (KUST), Khyber Pakhtunkhwa. It focused on the information requirements of the post-graduate students of the university, the pattern they use for seeking information, and the difficulties they face while seeking information. Design/Methodology/approach: This study used a quantitative approach, adapting a survey questionnaire method for data collection. The population of this study was composed of M.Phil. and Ph.D. students of 2019 and 2020 in the faculties of Physical and Numerical Sciences, Chemical and Pharmaceutical Sciences, Biological Sciences, and Social Sciences of KUST. The sample size was 260. Students were selected randomly. The study response rate was 77%, and data were analyzed through SPSS (22 versions). Key findings: The study revealed that Most students' information needs were for study and research activities, new knowledge, and career development. To fulfill these needs, the scholars use various sources and resources. The sources they used for information needs were journal articles, textbooks, and research projects commonly. For the information-seeking purpose, often, students prefer books that have some importance. The other factors that played an essential role in selecting material were topical relevance, Novelty, Recommended by colleagues, and publisher's reputation. Most of the students thought that Book Exhibitions, Open Access systems in the Library, and the Display of new arrivals could enhance the students' information-seeking. The main problem seeking information was faced by them was a shortage of printed information resources. Overall they wanted more facilities, enhancement in the library collection, and better services. Delimitations of the study: This study has not included 1) BS and M.Sc. Students of KUST; 2) The colleges and institutions affiliated with KUST; 3) This study was delimited only to the Post Graduate students of KUST. Practical implication(s): The findings of the study motivate the policymakers and authorities of KUST to restructure the information literacy programs to fulfill the scholars' information needs. It may inform the policymakers to know the difficulties faced by scholars during information seeking. Contribution to the knowledge: No significant work has been done on the students' information needs and seeking behaviour at KUST. The study analyzed the information needs and seeking behaviour of post graduate students. It brought a clear picture of information needs and seeking behaviour of scholars and addressed the problems faced by them during the seeking process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20needs%20of%20Pakistan" title="information needs of Pakistan">information needs of Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=information-seeking%20behaviors" title=" information-seeking behaviors"> information-seeking behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=postgraduate%20students" title=" postgraduate students"> postgraduate students</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20libraries" title=" university libraries"> university libraries</a>, <a href="https://publications.waset.org/abstracts/search?q=Kohat%20university%20of%20science%20and%20technology" title=" Kohat university of science and technology"> Kohat university of science and technology</a>, <a href="https://publications.waset.org/abstracts/search?q=Khyber%20Pakhtunkhwa" title=" Khyber Pakhtunkhwa"> Khyber Pakhtunkhwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a> </p> <a href="https://publications.waset.org/abstracts/150512/information-needs-and-seeking-behaviour-of-postgraduate-students-of-kohat-university-of-science-and-technology-khyber-pakhtunkhwa-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150512.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">91</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">127</span> An Easy-Applicable Method for In situ Silver Nanoparticles Preparation into Wool Fibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salwa%20Mowafi">Salwa Mowafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rehan"> Mohamed Rehan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hany%20Kafafy"> Hany Kafafy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, three different systems including room temperature, conventional water bath heating and microwave irradiation technique will be employed in the fabrication of silver nanoparticle-wool fibers.

The purpose of this research was to study distortion produced during welding in 2mm Mild Steel plate by simulating the welding process using Finite Element Analysis. Simulation of welding process requires a couple field transient analyses. At first a transient thermal analysis is performed and the temperature obtained from thermal analysis is used as input in structural analysis to find distortion. An actual weld sample is prepared and the weld distortion produced is measured. The simulated and actual results were in quite agreement with each other and it has been found that there is profound deflection at center of plate. Temperature dependent material properties play significant role in prediction of weld distortion. The results of this research can be used for prediction and control of weld distortion in large steel structures by changing different weld parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=welding%20simulation" title="welding simulation">welding simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=welding%20distortion" title=" welding distortion"> welding distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20dependent%20mechanical%20properties" title=" temperature dependent mechanical properties"> temperature dependent mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/12909/prediction-of-welding-induced-distortion-in-thin-metal-plates-using-temperature-dependent-material-properties-and-fea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12909.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">390</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">124</span> Level of Behavioral Development for Hepatitis C Virus Cases Versus Their Contacts: Does Infection Make a Difference and What Is Beyond?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammal%20M.%20Metwally">Ammal M.

To control infection, efforts should be spent to encourage healthy behavior. This study aimed to assess the level of behavioral development in order to create a positive environment for the adoption of the recommended behaviors. The study was conducted over one year from Jan. 2011 till Jan. 2012. Knowledge, attitude and behavior of 540 HCV patients and 102 of their contacts were assessed and the level of behavioral development was determined. The study revealed that the majority of patients and contacts knew that HCV infection is dangerous with perceived concern for early diagnosis and treatment. More than 75% knew the correct modes of transmission. The assessment showed positive attitudes towards the recommended practices with the intention to adopt those practices. Strategies to create opportunities to continue the recommended behaviors should be adopted together with the reinforcement of social support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatitis%20C%20virus" title="hepatitis C virus">hepatitis C virus</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20behavioral%20development" title=" level of behavioral development"> level of behavioral development</a>, <a href="https://publications.waset.org/abstracts/search?q=recommended%20behaviors" title=" recommended behaviors"> recommended behaviors</a> </p> <a href="https://publications.waset.org/abstracts/2281/level-of-behavioral-development-for-hepatitis-c-virus-cases-versus-their-contacts-does-infection-make-a-difference-and-what-is-beyond" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2281.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">397</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">123</span> FreGsd: A Framework for Golbal Software Requirement Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alsahli%20Abdulaziz%20Abdullah">Alsahli Abdulaziz Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Ullah%20Khan"> Hameed Ullah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software development nowadays is more and more using global ways of development instead of normal development enviroment where development occur in one location.

The high demand of mobile data rates require improved networks, which is a challenge for the operators in terms of maintaining the quality of experience (QoE) for their consumers. In live video transmission, there is a sheer need for live surveillance of the videos in order to maintain the quality of the network. For this purpose objective algorithms are employed to monitor the quality of the videos that are transmitted over a network. In order to test these objective algorithms, subjective quality assessment of the streamed videos is required, as the human eye is the best source of perceptual assessment. In this paper we have conducted subjective evaluation of videos with varying spatial and temporal impairments. These videos were impaired with frame freezing distortions so that the impact of frame freezing on the quality of experience could be studied. We present subjective Mean Opinion Score (MOS) for these videos that can be used for fine tuning the objective algorithms for video quality assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frame%20freezing" title="frame freezing">frame freezing</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20opinion%20score" title=" mean opinion score"> mean opinion score</a>, <a href="https://publications.waset.org/abstracts/search?q=objective%20assessment" title=" objective assessment"> objective assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20evaluation" title=" subjective evaluation"> subjective evaluation</a> </p> <a href="https://publications.waset.org/abstracts/26962/subjective-quality-assessment-for-impaired-videos-with-varying-spatial-and-temporal-information" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26962.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">494</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">121</span> Managing Incomplete PSA Observations in Prostate Cancer Data: Key Strategies and Best Practices for Handling Loss to Follow-Up and Missing Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madiha%20Liaqat">Madiha Liaqat</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Ahmed%20Khan"> Rehan Ahmed Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Kamal"> Shahid Kamal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple imputation with delta adjustment is a versatile and transparent technique for addressing univariate missing data in the presence of various missing mechanisms. This approach allows for the exploration of sensitivity to the missing-at-random (MAR) assumption. In this review, we outline the delta-adjustment procedure and illustrate its application for assessing the sensitivity to deviations from the MAR assumption. By examining diverse missingness scenarios and conducting sensitivity analyses, we gain valuable insights into the implications of missing data on our analyses, enhancing the reliability of our study's conclusions. In our study, we focused on assessing logPSA, a continuous biomarker in incomplete prostate cancer data, to examine the robustness of conclusions against plausible departures from the MAR assumption. We introduced several approaches for conducting sensitivity analyses, illustrating their application within the pattern mixture model (PMM) under the delta adjustment framework. This proposed approach effectively handles missing data, particularly loss to follow-up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=loss%20to%20follow-up" title="loss to follow-up">loss to follow-up</a>, <a href="https://publications.waset.org/abstracts/search?q=incomplete%20response" title=" incomplete response"> incomplete response</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20imputation" title=" multiple imputation"> multiple imputation</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a> </p> <a href="https://publications.waset.org/abstracts/175725/managing-incomplete-psa-observations-in-prostate-cancer-data-key-strategies-and-best-practices-for-handling-loss-to-follow-up-and-missing-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175725.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">89</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">120</span> The Term Structure of Government Bond Yields in an Emerging Market: Empirical Evidence from Pakistan Bond Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wali%20Ullah">Wali Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nishat"> Muhammad Nishat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigates the extent to which the so called Nelson-Siegel model (DNS) and its extended version that accounts for time varying volatility (DNS-EGARCH) can optimally fit the yield curve and predict its future path in the context of an emerging economy. For the in-sample fit, both models fit the curve remarkably well even in the emerging markets. However, the DNS-EGARCH model fits the curve slightly better than the DNS. Moreover, both specifications of yield curve that are based on the Nelson-Siegel functional form outperform the benchmark VAR forecasts at all forecast horizons. The DNS-EGARCH comes with more precise forecasts than the DNS for the 6- and 12-month ahead forecasts, while the two have almost similar performance in terms of RMSE for the very short forecast horizons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=yield%20curve" title="yield curve">yield curve</a>, <a href="https://publications.waset.org/abstracts/search?q=forecasting" title=" forecasting"> forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20markets" title=" emerging markets"> emerging markets</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a>, <a href="https://publications.waset.org/abstracts/search?q=EGARCH" title=" EGARCH"> EGARCH</a> </p> <a href="https://publications.waset.org/abstracts/17242/the-term-structure-of-government-bond-yields-in-an-emerging-market-empirical-evidence-from-pakistan-bond-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17242.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">539</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">119</span> Customers’ Acceptability of Islamic Banking: Employees’ Perspective in Peshawar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahira%20Imtiaz">Tahira Imtiaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Ullah"> Karim Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to incorporate the banks employees’ perspective on acceptability of Islamic banking by the customers of Peshawar. A qualitative approach is adopted for which six in-depth interviews with employees of Islamic banks are conducted. The employees were asked to share their experience regarding customers’ acceptance attitude towards acceptability of Islamic banking. Collected data was analyzed through thematic analysis technique and its synthesis with the current literature. Through data analysis a theoretical framework is developed, which highlights the factors which drive customers towards Islamic banking, as witnessed by the employees. The practical implication of analyzed data evident that a new model could be developed on the basis of four determinants of human preference namely: inner satisfaction, time, faith and market forces.
