This paper, which has a twofold objective, will push revisionist readings a step further by putting forward the thesis that revolutionary praxis has been an enduring concern for Adorno, surfacing throughout his entire work. On the other hand, it will hold that his understanding of the relationships between theory and praxis, which will be explained by referring to Ernst Bloch’s distinction between the warm and cold currents of Marxism, can help to interpret the paralysis of revolutionary practice in our own time under a new light. Philosophy and its tasks have been an enduring topic of Adorno’s work from the 1930s to Negativ Dialektik. The writings in which he develops these ideas stand among his most obscure and abstract so that their strong ties to the political have remained mainly overlooked. Adorno’s undertaking of criticizing and ‘redeeming’ philosophy and metaphysics is inseparable from a care for retrieving the capacity to act in the world and to change it. Philosophical problems are immanent to sociological problems, and vice versa, he underlines in his Metaphysik. Begriff and Problem. The issue of truth cannot be severed from the contingent context of a given idea. As a critical undertaking extracting its contents from reality, which is what philosophy should be from Adorno's perspective, the latter has the potential to fully reveal the reification of the individual and consciousness resulting from capitalist economic and cultural domination, thus opening the way to resistance and revolutionary change. While this project, according to his usual method, is sketched mainly in negative terms, it also exhibits positive contours which depict a socialist society. Only in the latter could human suffering end, and mutilated individuals experiment with reconciliation in an authentic way. That Adorno’s continuous plea for philosophy’s self-critic and renewal hides an enduring concern for revolutionary praxis emerges clearly from a careful philosophical analysis of his writings on philosophy and a selection of his sociological work, coupled with references to his correspondences. This study points to the necessity of a serious re-evaluation of Adorno’s relationship to the political, which will impact on the interpretation of his whole oeuvre, is much needed. In the second place, Adorno's dialectical conception of theory and praxis is enlightening for our own time, since it suggests that we are experiencing a phase of creative latency rather an insurmountable impasse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frankfurt%20school" title="Frankfurt school">Frankfurt school</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy%20and%20revolution" title=" philosophy and revolution"> philosophy and revolution</a>, <a href="https://publications.waset.org/abstracts/search?q=revolutionary%20praxis" title=" revolutionary praxis"> revolutionary praxis</a>, <a href="https://publications.waset.org/abstracts/search?q=Theodor%20W.%20Adorno" title=" Theodor W.

This enhancement facilitates improved decision-making throughout the banking organization. Decision tree analysis is a tool that visually outlines potential outcomes, costs, and consequences of complex decisions. It is particularly beneficial for analyzing quantitative data and making decisions based on numerical values. By calculating the expected value of each outcome, decision tree analysis can help assess the best course of action. In the context of banking, decision tree analysis can assist lenders in evaluating a customer’s creditworthiness, thereby preventing losses. However, applying these tools in developing countries may face several limitations, such as data availability, lack of technological infrastructure and resources, lack of skilled professionals, cultural factors, and cost. Moreover, decision trees can create overly complex models that do not generalize well to new data, known as overfitting. They can also be sensitive to small changes in the data, which can result in different tree structures and can become computationally expensive when dealing with large datasets. In conclusion, while risk management indicators and decision tree analysis are beneficial for decision-making in banks, their effectiveness is contingent upon how they are implemented and utilized by the board of directors, especially in the context of developing countries. It’s important to consider these limitations when planning to implement these tools in developing countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20management%20indicators" title="risk management indicators">risk management indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20tree%20analysis" title=" decision tree analysis"> decision tree analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=developing%20countries" title=" developing countries"> developing countries</a>, <a href="https://publications.waset.org/abstracts/search?q=board%20of%20directors" title=" board of directors"> board of directors</a>, <a href="https://publications.waset.org/abstracts/search?q=bank%20performance" title=" bank performance"> bank performance</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management%20strategy" title=" risk management strategy"> risk management strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=banking%20institutions" title=" banking institutions"> banking institutions</a> </p> <a href="https://publications.waset.org/abstracts/176212/using-risk-management-indicators-in-decision-tree-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176212.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">65</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">19132</span> Quartic Spline Method for Numerical Solution of Self-Adjoint Singularly Perturbed Boundary Value Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Mohammadi">Reza Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using quartic spline, we develop a method for numerical solution of singularly perturbed two-point boundary-value problems.

The proposed method is based on the use of three orthogonal nonlinear components which is unlike the high-order SAC functions. So, the generator synthesized by the proposed method has separate sets of control and information inputs. The proposed method proves its simplicity and the implementation ability. The proposed method allows synthesizing a SAC function generator with fixed control and information inputs. This ensures greater efficiency of the built-in oscillator compared to high-order SAC functions that can be used as a generator. Accordingly, the method is completely formalized and implemented as a software product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boolean%20function" title="boolean function">boolean function</a>, <a href="https://publications.waset.org/abstracts/search?q=controlled%20balanced%20boolean%20function" title=" controlled balanced boolean function"> controlled balanced boolean function</a>, <a href="https://publications.waset.org/abstracts/search?q=strictly%20avalanche%20criteria" title=" strictly avalanche criteria"> strictly avalanche criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=orthogonal%20nonlinear" title=" orthogonal nonlinear"> orthogonal nonlinear</a> </p> <a href="https://publications.waset.org/abstracts/95654/method-of-synthesis-of-controlled-generators-balanced-a-strictly-avalanche-criteria-functions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95654.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">160</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">19130</span> An Improved Amplified Sway Method for Semi-Rigidly Jointed Sway Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Hakim%20Chikho">Abdul Hakim Chikho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple method of calculating satisfactory of the effect of instability on the distribution of in-plane bending moments in unbraced semi-rigidly multistory steel framed structures is presented in this paper. This method, which is a modified form of the current amplified sway method of BS5950: part1:2000, uses an approximate load factor at elastic instability in each storey of a frame which in turn dependent up on the axial loads acting in the columns. The calculated factors are then used to represent the geometrical deformations due to the presence of axial loads, acting in that storey. Only a first order elastic analysis is required to accomplish the calculation.

The use of this method has always been non-popular amongst the parliamentarian candidates due to the amount of times and energy that they need to spent with the constituents. However, due to many parliamentarian corruption cases in the last five years period, some political party have been losing peoples trust. That political party trust lost had also affecting the parliamentarian candidates electability, so they invent some creative campaign method that involving their constituent with more intimates and friendly environment. In this paper, an observation is done to a parliamentarian candidate from Partai Keadilan Sejahtera (Prosperous Justice Party) in Bandung and Cimahi City area, West Java. This Parliamentraian candidate is known for her personal-approach campaign method such as a puppet show, hanging out with group of ex-bike gang leaders, and going fishing with the constituent. This paper will compare her method with other parliamentarian candidates from the same party as her that mostly use mainstream campaign method such as open speech, print media, an other one way campaign method. While the other parliamentarian candidates failed to reach the parliamentarian threshold, the participatory method had proven as an effective method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=participatory%20culture" title="participatory culture">participatory culture</a>, <a href="https://publications.waset.org/abstracts/search?q=Indonesian%20parliamentary%20election" title=" Indonesian parliamentary election"> Indonesian parliamentary election</a>, <a href="https://publications.waset.org/abstracts/search?q=Prosperous%20Justice%20Party" title=" Prosperous Justice Party"> Prosperous Justice Party</a>, <a href="https://publications.waset.org/abstracts/search?q=electability" title=" electability"> electability</a> </p> <a href="https://publications.waset.org/abstracts/10719/the-use-of-culture-as-a-campaign-method-in-indonesian-parliamentary-election" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10719.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">272</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">19128</span> An Analytical Study on the Vibration Reduction Method of Railway Station Using TPU</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinho%20Hur">Jinho Hur</a>, <a href="https://publications.waset.org/abstracts/search?q=Minjung%20Shin"> Minjung Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Heekyu%20Kim"> Heekyu Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In many places, new railway constructions in the city are being used to build a viaduct station to take advantage of the space below the line, for difficulty of securing railway site and disconnections of areas. The space under the viaduct has limited to use by noise and vibration. In order to use it for various purposes, reducing noise and vibration is required. The vibration reduction method for new structures is recently developed enough to use as accommodation, but the reduction method for existing structures is still far-off. In this study, it suggests vibration reduction method by filling vibration reduction material to column members which is path of structure-bone-noise from trains run. Because most of railroad stations are reinforced concrete structures. It compares vibration reduction of station applied the method and original station by FEM analysis. As a result, reduction of vibration acceleration level in bandwidth 15~30Hz can be reduced. Therefore, using this method for viaduct railroad station, vibration of station is expected to be reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structure%20borne%20noise" title="structure borne noise">structure borne noise</a>, <a href="https://publications.waset.org/abstracts/search?q=TPU" title=" TPU"> TPU</a>, <a href="https://publications.waset.org/abstracts/search?q=viaduct%20rail%20station" title=" viaduct rail station"> viaduct rail station</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20reduction%20method" title=" vibration reduction method"> vibration reduction method</a> </p> <a href="https://publications.waset.org/abstracts/24122/an-analytical-study-on-the-vibration-reduction-method-of-railway-station-using-tpu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24122.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">547</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">19127</span> Application of Two Stages Adaptive Neuro-Fuzzy Inference System to Improve Dissolved Gas Analysis Interpretation Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kharisma%20Utomo%20Mulyodinoto">Kharisma Utomo Mulyodinoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Suwarno"> Suwarno</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Abu-Siada"> A.

A number of methods are used to interpret the dissolved gas from transformer oil sample: Doernenberg Ratio Method, IEC (International Electrotechnical Commission) Ratio Method, and Duval Triangle Method. While the assessment of dissolved gas within transformer oil samples has been standardized over the past two decades, analysis of the results is not always straight forward as it depends on personnel expertise more than mathematical formulas. To get over this limitation, this paper is aimed at improving the interpretation of Doernenberg Ratio Method, IEC Ratio Method, and Duval Triangle Method using Two Stages Adaptive Neuro-Fuzzy Inference System (ANFIS). Dissolved gas analysis data from 520 faulty transformers was analyzed to establish the proposed ANFIS model. Results show that the developed ANFIS model is accurate and can standardize the dissolved gas interpretation process with accuracy higher than 90%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANFIS" title="ANFIS">ANFIS</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolved%20gas%20analysis" title=" dissolved gas analysis"> dissolved gas analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Doernenberg%20ratio%20method" title=" Doernenberg ratio method"> Doernenberg ratio method</a>, <a href="https://publications.waset.org/abstracts/search?q=Duval%20triangular%20method" title=" Duval triangular method"> Duval triangular method</a>, <a href="https://publications.waset.org/abstracts/search?q=IEC%20ratio%20method" title=" IEC ratio method"> IEC ratio method</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a> </p> <a href="https://publications.waset.org/abstracts/103022/application-of-two-stages-adaptive-neuro-fuzzy-inference-system-to-improve-dissolved-gas-analysis-interpretation-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103022.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">154</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">19126</span> Banning Gender: Movements to Suppress Gender Studies in the U.S. and Global Contexts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tracey%20Jean%20Boisseau">Tracey Jean Boisseau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the United States and around the world, we see liberal democracies attacked, from within and without, on a number of grounds. One of the primary assaults on the liberal ideology of feminism has been to ban or severely curtail the teaching of and scholarship on gender as constructed rather than as a biological and binarist component of human identity. On every continent, women’s and gender studies at the university level have become targets of rightwing movements aligning with authoritarian regimes to suppress queer and trans people as well as feminist scholars and academics who define gender as fluid, contingent on culture, and as reflective of a political commitment rather than timeless, sacred, natural, biological, or god-given. Rightwing movements calling for an end to gender studies have put already-marginalized academic and scholarly projects under new scrutiny, in some cases resulting in the dismantlement of long-standing women’s and gender studies programs. This paper evaluates the cross-cultural effects such movements have had on our discipline worldwide and documents the strategic responses engaged in by gender studies scholars and leaders to resist the erasure of our field. Evidence is drawn from surveys of thousands of programs and dozens of interviews conducted in the past year with gender studies scholars, administrators, and practitioners. This paper’s main objective is to highlight the international linkages between movements aiming to suppress or erase gender studies as a field of research and teaching and to identify collaborative responses and promising solutions that can protect our discipline from these assaults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-feminist" title="anti-feminist">anti-feminist</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-LGBTQ" title=" anti-LGBTQ"> anti-LGBTQ</a>, <a href="https://publications.waset.org/abstracts/search?q=authoritarianism" title=" authoritarianism"> authoritarianism</a>, <a href="https://publications.waset.org/abstracts/search?q=movements" title=" movements"> movements</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20studies" title=" gender studies"> gender studies</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a> </p> <a href="https://publications.waset.org/abstracts/165696/banning-gender-movements-to-suppress-gender-studies-in-the-us-and-global-contexts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165696.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">81</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">19125</span> A Series Solution of Fuzzy Integro-Differential Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Mosleh">Maryam Mosleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmood%20Otadi"> Mahmood Otadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The hybrid differential equations have a wide range of applications in science and engineering.

The tie force (TF) method is one of the main design approaches for progressive collapse. As the TF method is a simplified method, further investigations on the reliability of the method is necessary. This study aims to develop an improved TF method to design the cross wall structures for progressive collapse. To this end, the pullout behavior of strands in grout was firstly analyzed; and then, by considering the tie force-slip relationship in the friction stage together with the catenary action mechanism, a comprehensive analytical method was developed. The reliability of this approach is verified by the experimental results of concrete block pullout tests and full scale floor-to-floor joints tests undertaken by Portland Cement Association (PCA). Discrepancies in the tie force between the analytical results and codified specifications have suggested the deficiency of TF method, hence an improved model based on the analytical results has been proposed to address this concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20wall" title="cross wall">cross wall</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=ties%20force%20method" title=" ties force method"> ties force method</a>, <a href="https://publications.waset.org/abstracts/search?q=catenary" title=" catenary"> catenary</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a> </p> <a href="https://publications.waset.org/abstracts/1653/an-improved-tie-force-method-for-progressive-collapse-resistance-design-of-precast-concrete-cross-wall-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1653.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">476</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">19123</span> The Effect of Accounting Quality on Contribution-In-Kind Valuation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Heyjung%20Sonu">Catherine Heyjung Sonu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the effect of accounting quality on the process in which stock price is determined by focusing on contribution-in-kind valuations using Korean setting. In Korea, a number of chaebol firms have transformed into holding company system starting in 2003. With an attempt to gain as much voting right, management sold shares of subsidiaries to purchase shares of the holding company. In so doing, management of these firms received share issues for the contribution in kind that has been made to obtain additional shares of the holding company. The price of these share issues against contribution in kind is allowed to be discounted up to 30%. Using this interesting setting in Korea, this paper examines whether accounting quality affects the extent of the discount applied to the share issues. If the accounting quality of the firm for which the management is receiving share issues is poor, the extent of discount is likely to be high. The extent of discount is likely lower for firms with superior accounting quality. Using 24 cases, we find that, on average, the extent of discount is larger for share issues in which the accounting quality, proxied by the absolute value of discretionary accruals, is poor. This paper provides insight by examining the effect of accounting quality on the stock market. It sheds light on the intersection between finance and accounting research and should be of interest to researchers and practitioners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Accounting%20quality" title="Accounting quality">Accounting quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Contribution-in-kind" title=" Contribution-in-kind"> Contribution-in-kind</a>, <a href="https://publications.waset.org/abstracts/search?q=discount" title=" discount"> discount</a>, <a href="https://publications.waset.org/abstracts/search?q=holding%20company" title=" holding company"> holding company</a> </p> <a href="https://publications.waset.org/abstracts/87381/the-effect-of-accounting-quality-on-contribution-in-kind-valuation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87381.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">19122</span> The Improved Element Free Galerkin Method for 2D Heat Transfer Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Debbabi">Imen Debbabi</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9di%20BelHadjSalah"> Hédi BelHadjSalah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Improved Element Free Galerkin (IEFG) method is presented to treat the steady states and the transient heat transfer problems.

At the same time, within any given network, some network members will have a more important, more central position on account of their greater number of connections or their capacity as “bridges” connecting members of different network cliques. The logic of network structure and position is at the heart of what is known as social network analysis, and this paper applies this logic to the study of the stock market. Using an array of data analytics and machine learning tools, this study will examine 17 million Twitter messages discussing the stocks of the firms in the S&P 1,500 index in 2018. Each of these 1,500 stocks has a distinct Twitter discussion network that varies in terms of core network characteristics such as size, density, influence, norms and values, level of activity, and embedded resources. The study’s core proposition is that the ultimate effect of any market-relevant information is contingent on the characteristics of the network through which it flows. To test this proposition, this study operationalizes each of the core network characteristics and examines their influence on market reactions to 2018 quarterly earnings announcement events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20analytics" title="data analytics">data analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=investor-to-investor%20communication" title=" investor-to-investor communication"> investor-to-investor communication</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20network%20analysis" title=" social network analysis"> social network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Twitter" title=" Twitter"> Twitter</a> </p> <a href="https://publications.waset.org/abstracts/152263/twitter-ego-networks-and-the-capital-markets-a-social-network-analysis-perspective-of-market-reactions-to-earnings-announcement-events" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152263.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">127</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">19120</span> Adomian’s Decomposition Method to Functionally Graded Thermoelastic Materials with Power Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdy%20M.%20Youssef">Hamdy M.

Objective: The aim was to explore and describe nurses’ (medication administrators) perceptions regarding medication administration safety-related culture, incidence, causes, and reporting in the Gauteng Province of South Africa, and to determine any relationships between perceived variables concerned with medication safety (safety culture, incidences, causes, reporting of incidences, and reasons for non-reporting). Method: A quantitative research design was used through which self-administered online surveys were sent to 768 nurses (medication administrators) (n=217). The response rate was 28.26%. The survey instrument was synthesised from the Agency of Healthcare Research and Quality (AHRQ) Hospital Survey on Patient Safety Culture, the Registered Nurse Forecasting (RN4CAST) survey, a survey list prepared from a systematic review aimed at generating a comprehensive list of medication administration error causes and the Medication Administration Error Reporting Survey from Wakefield. Exploratory and confirmatory factor analyses were used to determine the validity and reliability of the survey. Descriptive and inferential statistical data analysis were used to analyse quantitative data. Relationships and correlations were identified between items, subscales and biographic data by using Spearmans’ Rank correlations, T-Tests and ANOVAs (Analysis of Variance). Nurses reported on their perceptions of medication administration safety-related culture, incidence, causes, and reporting in the Gauteng Province. Results: Units’ teamwork deemed satisfactory, punitive responses to errors accentuated. “Crisis mode” working, concerns regarding mistake recording and long working hours disclosed as impacting patient safety. Overall medication safety graded mostly positively. Work overload, high patient-nurse ratios, and inadequate staffing implicated as error-inducing. Medication administration errors were reported regularly. Fear and administrative response to errors effected non-report. Non-report of errors’ reasons was affected by non-punitive safety culture. Conclusions: Medication administration safety improvement is contingent on fostering a non-punitive safety culture within units. Anonymous medication error reporting systems and auditing nurses’ workload are recommended in the quest of improved medication safety within Gauteng Province private hospitals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incidence" title="incidence">incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=medication%20administration%20errors" title=" medication administration errors"> medication administration errors</a>, <a href="https://publications.waset.org/abstracts/search?q=medication%20safety" title=" medication safety"> medication safety</a>, <a href="https://publications.waset.org/abstracts/search?q=reporting" title=" reporting"> reporting</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20culture" title=" safety culture"> safety culture</a> </p> <a href="https://publications.waset.org/abstracts/184523/nurse-reported-perceptions-of-medication-safety-in-private-hospitals-in-gauteng-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184523.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">62</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">19117</span> An Empirical Analysis of the Effects of Corporate Derivatives Use on the Underlying Stock Price Exposure: South African Evidence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edson%20Vengesai">Edson Vengesai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Derivative products have become essential instruments in portfolio diversification, price discovery, and, most importantly, risk hedging.

Given the growing interest in using derivatives in risk management and portfolio engineering, this study examines the practical impact of derivative usage on the underlying stock price exposure and systematic risk. The paper uses data from South African listed firms. The study employs GARCH models to understand the effect of derivative uses on conditional stock volatility. The GMM models are used to estimate the effect of derivatives use on stocks' systematic risk as measured by Beta and on the total risk of stocks as measured by the standard deviation of returns. The results provide evidence on whether derivatives use is instrumental in reducing stock returns' systematic and total risk. The results are subjected to numerous controls for robustness, including financial leverage, firm size, growth opportunities, and macroeconomic effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=derivatives%20use" title="derivatives use">derivatives use</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility" title=" volatility"> volatility</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20price%20exposure" title=" stock price exposure"> stock price exposure</a> </p> <a href="https://publications.waset.org/abstracts/156599/an-empirical-analysis-of-the-effects-of-corporate-derivatives-use-on-the-underlying-stock-price-exposure-south-african-evidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156599.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">116</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">19116</span> Analysis of the Aquifer Vulnerability of a Miopliocene Arid Area Using Drastic and SI Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Majour">H.

In this study, our choice dealt with two recent complementary methods using category mapping of index with weighting criteria (Point County Systems Model MSCP) namely the standard DRASTIC method and SI (Susceptibility Index). At present, these two methods are the most used for the mapping of the intrinsic vulnerability of groundwater. Two classes of groundwater vulnerability in the Biskra sandy aquifer were identified by the DRASTIC method (average and high) and the SI method (very high and high). Integrated analysis has revealed that the high class is predominant for the DRASTIC method whereas for that of SI the preponderance is for the very high class. Furthermore, we notice that the method SI estimates better the vulnerability for the pollution in nitrates, with a rate of 85 % between the concentrations in nitrates of groundwater and the various established classes of vulnerability, against 75 % for the DRASTIC method. By including the land use parameter, the SI method produced more realistic results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DRASTIC" title="DRASTIC">DRASTIC</a>, <a href="https://publications.waset.org/abstracts/search?q=SI" title=" SI"> SI</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=Biskra%20sandy%20aquifer" title=" Biskra sandy aquifer"> Biskra sandy aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/24830/analysis-of-the-aquifer-vulnerability-of-a-miopliocene-arid-area-using-drastic-and-si-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24830.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">492</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">19115</span> Chaotic Sequence Noise Reduction and Chaotic Recognition Rate Improvement Based on Improved Local Geometric Projection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rubin%20Dan">Rubin Dan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xingcai%20Wang"> Xingcai Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziyang%20Chen"> Ziyang Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A chaotic time series noise reduction method based on the fusion of the local projection method, wavelet transform, and particle swarm algorithm (referred to as the LW-PSO method) is proposed to address the problem of false recognition due to noise in the recognition process of chaotic time series containing noise. The method first uses phase space reconstruction to recover the original dynamical system characteristics and removes the noise subspace by selecting the neighborhood radius; then it uses wavelet transform to remove D1-D3 high-frequency components to maximize the retention of signal information while least-squares optimization is performed by the particle swarm algorithm. The Lorenz system containing 30% Gaussian white noise is simulated and verified, and the phase space, SNR value, RMSE value, and K value of the 0-1 test method before and after noise reduction of the Schreiber method, local projection method, wavelet transform method, and LW-PSO method are compared and analyzed, which proves that the LW-PSO method has a better noise reduction effect compared with the other three common methods. The method is also applied to the classical system to evaluate the noise reduction effect of the four methods and the original system identification effect, which further verifies the superiority of the LW-PSO method. Finally, it is applied to the Chengdu rainfall chaotic sequence for research, and the results prove that the LW-PSO method can effectively reduce the noise and improve the chaos recognition rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Schreiber%20noise%20reduction" title="Schreiber noise reduction">Schreiber noise reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelet%20transform" title=" wavelet transform"> wavelet transform</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=0-1%20test%20method" title=" 0-1 test method"> 0-1 test method</a>, <a href="https://publications.waset.org/abstracts/search?q=chaotic%20sequence%20denoising" title=" chaotic sequence denoising"> chaotic sequence denoising</a> </p> <a href="https://publications.waset.org/abstracts/150600/chaotic-sequence-noise-reduction-and-chaotic-recognition-rate-improvement-based-on-improved-local-geometric-projection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150600.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">207</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">19114</span> Prioritizing Ecosystem Services for South-Central Regions of Chile: An Expert-Based Spatial Multi-Criteria Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yenisleidy%20Martinez%20Martinez">Yenisleidy Martinez Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Yannay%20Casas-Ledon"> Yannay Casas-Ledon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%20Dewulf"> Jo Dewulf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ecosystem services (ES) concept has contributed to draw attention to the benefits ecosystems generate for people and how necessary natural resources are for human well-being. The identification and prioritization of the ES constitute the first steps to undertake conservation and valuation initiatives on behalf of people. Additionally, mapping the supply of ES is a powerful tool to support decision making regarding the sustainable management of landscape and natural resources. In this context, the present study aimed to identify, prioritize and map the primary ES in Biobio and Nuble regions using a methodology that combines expert judgment, multi-attribute evaluation methods, and Geographic Information Systems (GIS). Firstly, scores about the capacity of different land use/cover types to supply ES and the importance attributed to each service were obtained from experts and stakeholders via an online survey. Afterward, the ES assessment matrix was constructed, and the weighted linear combination (WLC) method was applied to mapping the overall capacity of supply of provisioning, regulating and maintenance, and cultural services. Finally, prioritized ES for the study area were selected and mapped. The results suggest that native forests, wetlands, and water bodies have the highest supply capacities of ES, while urban and industrial areas and bare areas have a very low supply of services. On the other hand, fourteen out of twenty-nine services were selected by experts and stakeholders as the most relevant for the regions. The spatial distribution of ES has shown that the Andean Range and part of the Coastal Range have the highest ES supply capacity, mostly regulation and maintenance and cultural ES. This performance is related to the presence of native forests, water bodies, and wetlands in those zones. This study provides specific information about the most relevant ES in Biobio and Nuble according to the opinion of local stakeholders and the spatial identification of areas with a high capacity to provide services. These findings could be helpful as a reference by planners and policymakers to develop landscape management strategies oriented to preserve the supply of services in both regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20services" title="ecosystem services">ecosystem services</a>, <a href="https://publications.waset.org/abstracts/search?q=expert%20judgment" title=" expert judgment"> expert judgment</a>, <a href="https://publications.waset.org/abstracts/search?q=mapping" title=" mapping"> mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20decision%20making" title=" multi-criteria decision making"> multi-criteria decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=prioritization" title=" prioritization"> prioritization</a> </p> <a href="https://publications.waset.org/abstracts/130534/prioritizing-ecosystem-services-for-south-central-regions-of-chile-an-expert-based-spatial-multi-criteria-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130534.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">133</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">19113</span> Numerical Solution of Integral Equations by Using Discrete GHM Multiwavelet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Archit%20Yajnik">Archit Yajnik</a>, <a href="https://publications.waset.org/abstracts/search?q=Rustam%20Ali"> Rustam Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, numerical method based on discrete GHM multiwavelets is presented for solving the Fredholm integral equations of second kind.

A mathematical model was constructed to analyze the influence of each design parameter on this lapping method. To validate this new lapping method, an orthogonal experiment was conducted with cemented carbide balls (YG6). The simulation model was verified and the optimal lapping parameters were derived. The results show that the surface roundness of the balls reaches to 0.65um from 2um in 1 hour using this lapping method.

Canthaxanthin has been analyzed using High Performance Liquid Chromatography (HPLC) system with various ways of pretreatment methods. Four official methods for verification of canthaxanthin at FSA (UK), AOAC (US), EFSA (EU) and MHLW (Japan) were compared to improve its analytical and the pretreatment method. The Linearity, the limit of detection (LOD), the limit of quantification (LOQ), the accuracy, the precision and the recovery ratio were determined from each method with modification in pretreatment method. All HPLC methods exhibited correlation coefficients of calibration curves for canthaxanthin as 0.9999. The analysis methods from FSA, AOAC, and MLHW showed the LOD of 0.395 ppm, 0.105 ppm, and 0.084 ppm, and the LOQ of 1.196 ppm, 0.318 ppm, 0.254 ppm, respectively. Among tested methods, HPLC method of MHLW with modification in pretreatments was finally selected for the analysis of canthaxanthin in lab, because it exhibited the resolution factor of 4.0 and the selectivity of 1.30. This analysis method showed a correlation coefficients value of 0.9999 and the lowest LOD and LOQ. Furthermore, the precision ratio was lower than 1 and the accuracy was almost 100%.
