Specifically, the paper will focus on the strategic implementation of Employee Resource Groups (ERGs) as powerful interventions for catalyzing culture change within modern workplaces. Edgar Schein's foundational theories on organizational culture and his renowned model of culture work will serve as the theoretical framework to guide the exploration of how ERGs can be harnessed as transformative tools in organizational development initiatives. Through a review of literature combined with content analysis, this paper will explore how ERGs align with Schein's principles, contribute to development, and drive positive cultural shifts toward inclusion and equity. The paper aims to provide practical insights for organizational leaders, HR practitioners, and change agents looking to integrate ERGs effectively into their culture change efforts, thereby advancing the field of organizational development informed by Schein's influential framework. The objective of the paper is to investigate and understand the intersection between Employee Resource Groups (ERGs) and Edgar Schein's Culture Work within the context of organizational development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inclusive%20leadership" title="inclusive leadership">inclusive leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=equity" title=" equity"> equity</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20resource%20groups" title=" employee resource groups"> employee resource groups</a>, <a href="https://publications.waset.org/abstracts/search?q=organization%20development" title=" organization development"> organization development</a> </p> <a href="https://publications.waset.org/abstracts/182113/leveraging-employee-resource-groups-ergs-as-agents-of-change-an-exploration-of-edgar-scheins-culture-work-in-organizational-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182113.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">80</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">156</span> In Life: Space as Doppelganger in “The House of Usher”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tu%C4%9F%C3%A7e%20Arslan">Tuğçe Arslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the dark and gloomy times of the Middle Ages, high, majestic, and frightening structures were revealed in the architectural field. Thus, gothic architecture began to find a place for itself in different areas and spread its influence. Gothic has found its place in almost every literary genre and manages to show itself as the dominant genre in the works it enters. It has exploited many concepts, such as a chest full of bad feelings, and creates a gloomy, scary, frightening, and pessimistic mood in the story with these concepts. One of the essential concepts it uses while creating these feelings is the concept of “Doppelganger.” With this concept, the authors make sense of the uncanny; at this point, they allow the spaces to act like characters, just like the uncanny feeling Edgar Allan Poe creates in his story “The Fall of the House of the Usher.” In this story by Edgar Allan Poe, attention should be paid to the symbolic link between the two, as “House of Usher” refers to the family and the building. And indeed, it is possible to see this minor rift as representative of a breakdown in family unity, specifically between Madeline and Roderick. Because although the home is not alive, it has some supernatural features that make it look like a living, breathing being. Therefore, the remainder of this paper will argue that apart from the apparent twins, the house should also qualify as a Doppelganger in the story. This study will first explore the physical and mental disorders of the twins and their journey to complement each other; next, in an attempt to demonstrate how the house as a non-living needs to be considered as a Doppelganger of the twins, a close reading on the house depictions will be scrutinized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Allan%20Poe" title="Edgar Allan Poe">Edgar Allan Poe</a>, <a href="https://publications.waset.org/abstracts/search?q=doppelganger" title=" doppelganger"> doppelganger</a>, <a href="https://publications.waset.org/abstracts/search?q=uncanny" title=" uncanny"> uncanny</a>, <a href="https://publications.waset.org/abstracts/search?q=gothic" title=" gothic"> gothic</a>, <a href="https://publications.waset.org/abstracts/search?q=space" title=" space"> space</a>, <a href="https://publications.waset.org/abstracts/search?q=home" title=" home"> home</a> </p> <a href="https://publications.waset.org/abstracts/156339/in-life-space-as-doppelganger-in-the-house-of-usher" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156339.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">121</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">155</span> A Psychoanalytical Approach to Edgar A.

Nowadays, psychoanalytic theory is applied to numerous fields. One of them is literature. Literary criticism has put into practice the basis of Freud’s idea to analyze literary works. This essay is about the analysis of Edgar A. Poe’s short story ‘The Tell-Tale Heart,’ under the lens of Freud’s psychoanalytical perspective. In 1919, it was published ‘Das Unheimliche’ (The Uncanny) by Freud. On this article, the famous Austrian psychoanalyst showed his explanations about what he called ‘the uncanny,’ and its relation to the human unconscious. In this paper, Freud’s famous article has been used to analyze Poe’s short story ‘The Tell-Tale Heart,’ and to find the analogies that exist between Poe’s macabre short story and Freud’s theory of ‘the uncanny.’ <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=psychoanalysis" title="psychoanalysis">psychoanalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20the%20unconscious" title=" theory of the unconscious"> theory of the unconscious</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20uncanny" title=" the uncanny"> the uncanny</a>, <a href="https://publications.waset.org/abstracts/search?q=unheimlich" title=" unheimlich"> unheimlich</a> </p> <a href="https://publications.waset.org/abstracts/71692/a-psychoanalytical-approach-to-edgar-a-poes-short-story-the-tell-tale-heart" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71692.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">644</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">154</span> Periodicity of Solutions of a Nonlinear Impulsive Differential Equation with Piecewise Constant Arguments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehtap%20Lafc%C4%B1">Mehtap Lafcı</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, oscillation, periodicity and convergence of solutions of linear differential equations with piecewise constant arguments have been significantly considered but there are only a few papers for impulsive differential equations with piecewise constant arguments.

It requires specific knowledge not only on how to use the tools for the task but also on the fundamentals of a 3D environment. In this work, we show that automatic generation of content can be achieved, from a scene script, by leveraging existing tools so that non-experts can easily engage in a 3D content generation without requiring vast amounts of time in exploring and learning how to use specific tools. This proposal carries several benefits, including flexible scene synthesis with different levels of detail. Our preliminary results show that the automatically generated content is comparable to the content generated by users with low experience in 3D modeling while vastly reducing the amount of time required for the generation and adds support to implement flexible scenarios for visual scene visualization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20virtualization" title="3D virtualization">3D virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=multimedia" title=" multimedia"> multimedia</a>, <a href="https://publications.waset.org/abstracts/search?q=scene%20script" title=" scene script"> scene script</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a> </p> <a href="https://publications.waset.org/abstracts/136994/a-step-towards-automating-the-synthesis-of-a-scene-script" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136994.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">266</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">152</span> Questionnaire for the Evaluation of Entrepreneurship Project Psychopedagogical Practices: Construction Proceedings and Validation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Costa-Lobo">Cristina Costa-Lobo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Fernandes"> Sandra Fernandes</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Magalh%C3%A3es"> Miguel Magalhães</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Dinis-Carvalho"> José Dinis-Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Regueiro"> Alfredo Regueiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Carvalho"> Ana Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is a report on the findings of the construction and the validation of a questionnaire monetized in a portuguese higher education context with undergraduate students.

Taguchi Orthogonal array was used to evaluate the influence of extrusion temperature, bed temperature, layer height, and infill on the dimensional accuracy of a 3D-Printed Polymer Model. A Zeiss T-SCAN CS 3D Scanner was used for dimensional evaluation of the printed parts within the limit of ±0,2 mm. The mold capabilities were tested with the printed model to check how it would interact with the green sand. With little adjustments in the 3D model, it was possible to produce rapid tools without the need for post-processing for iron casting. The results are important for reducing time and cost in the development of such tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20tooling" title=" rapid tooling"> rapid tooling</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20filament%20fabrication" title=" fused filament fabrication"> fused filament fabrication</a>, <a href="https://publications.waset.org/abstracts/search?q=casting%20mold" title=" casting mold"> casting mold</a> </p> <a href="https://publications.waset.org/abstracts/152307/accuracy-of-a-3d-printed-polymer-model-for-producing-casting-mold" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152307.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">142</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">150</span> Broiler Chickens Meat Qualities and Death on Arrival (DOA) In-Transit in Brazilian Tropical Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arlan%20S.%20Freitas">Arlan S.

In this particular region routinely the season is divided into dry and wet seasons. Three loads of 4,100 forty seven days old broiler were monitored from farm to slaughterhouse in a distance of 273 km (320 min), morning periods of August, September and October 2015 rainy days. Meat qualities were evaluated by determining the occurrence of PSE (pale, soft, exudative) meat and DFD (dark, firm, dry) meat. The percentage of DOA per loaded truck was determined by counting the dead broiler during the hanging step at the slaughtering plant. Results showed the occurrence of 26.30% of PSE and 2.49% of DFD and 0.45% of DOA. By having PSE- and DFD- meat means that the birds were under thermal and cold stress leading as consequence to a relative high DOA index. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20welfare" title="animal welfare">animal welfare</a>, <a href="https://publications.waset.org/abstracts/search?q=DFD" title=" DFD"> DFD</a>, <a href="https://publications.waset.org/abstracts/search?q=microclimatic%20profile" title=" microclimatic profile"> microclimatic profile</a>, <a href="https://publications.waset.org/abstracts/search?q=PSE" title=" PSE"> PSE</a> </p> <a href="https://publications.waset.org/abstracts/46722/broiler-chickens-meat-qualities-and-death-on-arrival-doa-in-transit-in-brazilian-tropical-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46722.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">410</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">149</span> Development and Validation of the Response to Stressful Situations Scale in the General Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9lia%20Barreto%20Carvalho">Célia Barreto Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolina%20da%20Motta"> Carolina da Motta</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Sousa"> Marina Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Joana%20Cabral"> Joana Cabral</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lu%C3%ADsa%20Carvalho"> Ana Luísa Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermelindo%20Peixoto"> Ermelindo Peixoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the current study was to develop and validate a Response to Stressful Situations Scale (RSSS) for the Portuguese population. This scale assesses the degree of stress experienced in scenarios that can constitute positive, negative and more neutral stressors, and also describes the physiological, emotional and behavioral reactions to those events according to their intensity. These scenario include typical stressor scenarios relevant to patients with schizophrenia, which are currently absent from most scale, assessing specific risks that these stressors may bring on subjects, which may prove useful in non-clinical and clinical populations (i.e. patients with mood or anxiety disorders, schizophrenia). Results from Principal Components Analysis and Confirmatory Factor Analysis of on two adult samples from general population allowed to confirm a three-factor model with good fit indices: χ2 (144)= 370.211, p = 0.000; GFI = 0.928; CFI = 0.927; TLI = 0.914, RMSEA = 0.055, P( rmsea ≤ 0.005) = 0.096; PCFI = 0.781. Further data analysis on the scale revealed that RSSS is an adequate assessment tool of stress response in adults to be used in further research and clinical settings, with good psychometric characteristics, adequate divergent and convergent validity, good temporal stability and high internal consistency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20events" title=" stress events"> stress events</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20response" title=" stress response"> stress response</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20vulnerability" title=" stress vulnerability"> stress vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/29203/development-and-validation-of-the-response-to-stressful-situations-scale-in-the-general-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29203.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">520</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">148</span> Accountability of Artificial Intelligence: An Analysis Using Edgar Morin’s Complex Thought</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvie%20Michel">Sylvie Michel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvie%20Gerbaix"> Sylvie Gerbaix</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Bidan"> Marc Bidan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial intelligence (AI) can be held accountable for its detrimental impacts. This question gains heightened relevance given AI's pervasive reach across various domains, magnifying its power and potential. The expanding influence of AI raises fundamental ethical inquiries, primarily centering on biases, responsibility, and transparency. This encompasses discriminatory biases arising from algorithmic criteria or data, accidents attributed to autonomous vehicles or other systems, and the imperative of transparent decision-making. This article aims to stimulate reflection on AI accountability, denoting the necessity to elucidate the effects it generates. Accountability comprises two integral aspects: adherence to legal and ethical standards and the imperative to elucidate the underlying operational rationale. The objective is to initiate a reflection on the obstacles to this "accountability," facing the challenges of the complexity of artificial intelligence's system and its effects. Then, this article proposes to mobilize Edgar Morin's complex thought to encompass and face the challenges of this complexity. The first contribution is to point out the challenges posed by the complexity of A.I., with fractional accountability between a myriad of human and non-human actors, such as software and equipment, which ultimately contribute to the decisions taken and are multiplied in the case of AI. Accountability faces three challenges resulting from the complexity of the ethical issues combined with the complexity of AI. The challenge of the non-neutrality of algorithmic systems as fully ethically non-neutral actors is put forward by a revealing ethics approach that calls for assigning responsibilities to these systems. The challenge of the dilution of responsibility is induced by the multiplicity and distancing between the actors. Thus, a dilution of responsibility is induced by a split in decision-making between developers, who feel they fulfill their duty by strictly respecting the requests they receive, and management, which does not consider itself responsible for technology-related flaws. Accountability is confronted with the challenge of transparency of complex and scalable algorithmic systems, non-human actors self-learning via big data. A second contribution involves leveraging E. Morin's principles, providing a framework to grasp the multifaceted ethical dilemmas and subsequently paving the way for establishing accountability in AI. When addressing the ethical challenge of biases, the "hologrammatic" principle underscores the imperative of acknowledging the non-ethical neutrality of algorithmic systems inherently imbued with the values and biases of their creators and society. The "dialogic" principle advocates for the responsible consideration of ethical dilemmas, encouraging the integration of complementary and contradictory elements in solutions from the very inception of the design phase. Aligning with the principle of organizing recursiveness, akin to the "transparency" of the system, it promotes a systemic analysis to account for the induced effects and guides the incorporation of modifications into the system to rectify deviations and reintroduce modifications into the system to rectify its drifts. In conclusion, this contribution serves as an inception for contemplating the accountability of "artificial intelligence" systems despite the evident ethical implications and potential deviations. Edgar Morin's principles, providing a lens to contemplate this complexity, offer valuable perspectives to address these challenges concerning accountability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accountability" title="accountability">accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=complexity" title=" complexity"> complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=ethics" title=" ethics"> ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=explainability" title=" explainability"> explainability</a>, <a href="https://publications.waset.org/abstracts/search?q=transparency" title=" transparency"> transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Morin" title=" Edgar Morin"> Edgar Morin</a> </p> <a href="https://publications.waset.org/abstracts/173596/accountability-of-artificial-intelligence-an-analysis-using-edgar-morins-complex-thought" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173596.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">63</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> The Special Testimony as a Methodology for Social Workers to Ensure the Rights of Children and Adolescents Who Are Victims of Sexual Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natany%20Rodrigues%20De%20Carvalho">Natany Rodrigues De Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Denise%20Bomtempo%20Birche%20De%20Carvalho"> Denise Bomtempo Birche De Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to analyze the Special Testimony as a methodology for social workers to ensure the rights of children and adolescents who are victims of sexual violence. The specific objectives are: a) to contextualize, through the specialized literature, the social history of childhood and adolescence; b) to investigate, in the scientific literature, the sexual violence against children and adolescents as an analytical category; c) identify, with the social workers, if there is any defense of children and adolescents in the special testimony. To answer the research objectives we use qualitative research, in three axes that complement each other: a) participant observation through the insertion in the research field (supervised internship I and II); b) survey of literature on the subject; c) semi-structured interviews with social workers of the TJDFT. We used content analysis to systematize and interpret the collected data. The results of the research were organized into three chapters with the following contents: a) literature review, contextualizing the social history of childhood and adolescence to the present; b) sexual violence against children and adolescents and their categories of analysis; c) understanding of the special testimony in the Federal District and Territories in guaranteeing the rights of children and adolescents, identifying their main points from the perspective of social workers. The results showed how the lack of interdisciplinarity in the Special Testimony can lead to the non-integral protection of children and adolescents victims of sexual violence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=childhood%20and%20adolescence" title="childhood and adolescence">childhood and adolescence</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20violence" title=" sexual violence"> sexual violence</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20testimony" title=" special testimony"> special testimony</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20work" title=" social work"> social work</a> </p> <a href="https://publications.waset.org/abstracts/87204/the-special-testimony-as-a-methodology-for-social-workers-to-ensure-the-rights-of-children-and-adolescents-who-are-victims-of-sexual-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87204.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">319</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> The Clinical Significance of Cutaneous Leishmaniasis in Immigrant and Refugee Populations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Promise%20Ufomadu">Promise Ufomadu</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Rodriguez"> Edgar Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Grace%20Lee"> Grace Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cutaneous Leishmaniasis (CL) is an infection caused by a variety of Leishmania species which are protozoan organisms that are typically carried by sandflies found in tropical regions.

At the same time, the traditional liquid-phase functionalization protocols can compromise physical integrity of the paper-like material up to its total disintegration. To avoid such undesirable effects, we explored the possibility of employing an alternative, solvent-free strategy for facile and nondestructive functionalization of GOP with two representative aliphatic amines, 1-octadecylamine (ODA) and 1,12-diaminododecane (DAD), as well as with two aromatic amines, 1-aminopyrene (AP) and 1,5-diaminonaphthalene (DAN). The functionalization was performed under moderate heating at 150-180 °C in vacuum. Under such conditions, it proceeds through both amidation and epoxy ring opening reactions. Comparative characterization of pristine and amine-functionalized GOP mats was carried out by using Fourier-transform infrared, Raman, and X-ray photoelectron spectroscopy (XPS), thermogravimetric (TGA) and differential thermal analysis, scanning electron and atomic force microscopy (SEM and AFM, respectively). Besides that, we compared the stability in water, wettability, electrical conductivity and elastic (Young's) modulus of GOP mats before and after amine functionalization. The highest content of organic species was obtained in the case of GOP-ODA, followed by GOP-DAD, GOP-AP and GOP-DAN samples. The covalent functionalization increased mechanical and thermal stability of GOP, as well as its electrical conductivity. The magnitude of each effect depends on the particular chemical structure of amine employed, which allows for tuning a given GOP property. Morphological characterization by using SEM showed that, compared to pristine graphene oxide paper, amine-modified GOP mats become relatively ordered layered assemblies, in which individual GO sheets are organized in a near-parallel pattern.

The decision that led us to choose IKEA for our casework has to do with the long history of the company since the 1940s and its high internationalization in 63 different markets. The company also has clear financial reports which aided us in the making of the present essay and naturally, was a factor that contributed to our decision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ikea" title="Ikea">Ikea</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20risk" title=" financial risk"> financial risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=hedge" title=" hedge"> hedge</a> </p> <a href="https://publications.waset.org/abstracts/186752/a-financial-analysis-of-the-current-state-of-ikea-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186752.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">52</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> The Impact of the Global Financial Crises on MILA Stock Markets </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Miriam%20Sosa">Miriam Sosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Ortiz"> Edgar Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Cabello"> Alejandra Cabello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the volatility changes and leverage effects of the MILA stock markets and their changes since the 2007 global financial crisis.

Tai Chi epitomises Yin and Yang, two interconnected opposite states of being. Undivided, they are one, a neutral state of consciousness that does not swing to either pole. It remains constant and even minded. Sound flows and vibrations cause movement, a physical response to the tempo. When an excessive movement is reached leads to stillness therefore, extreme Yang leads to Yin. Pop Music and Tai Chi are comparable to state of inner being versus a state of outer being, emotional control versus emotional expression, stillness, and movement; opposites that are independent of one another yet interdependent concepts in motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pop%20music" title="Pop music">Pop music</a>, <a href="https://publications.waset.org/abstracts/search?q=C-Pop" title=" C-Pop"> C-Pop</a>, <a href="https://publications.waset.org/abstracts/search?q=Tai%20Chi" title=" Tai Chi"> Tai Chi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ba%20Gua" title=" Ba Gua"> Ba Gua</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=entertainment%20education" title=" entertainment education"> entertainment education</a> </p> <a href="https://publications.waset.org/abstracts/148595/pop-music-and-tai-chi-movement-and-stillness-intertwined-in-the-contemporary-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148595.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">238</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">136</span> Product Placement and Advertising in Chinese Internet Dramas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Portugal%20Marques%20de%20Carvalho%20Lourenco">Patricia Portugal Marques de Carvalho Lourenco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the richness of product placement usage in Chinese IP dramas.

The aim of this study is to characterize the viscoelastic behavior of bone specimens, through stress relaxation and fatigue tests performed to trabecular bone samples from bovine femoral heads. Relaxation tests consisted on preloading the samples at five different magnitudes and evaluate them for 1020 seconds, adjusting the results to a KWW mathematical model. Fatigue tests consisted of 700 load cycles and analyze their status at the end of the tests. As a conclusion we have that between relaxation stress and each preload there is linear relation and for samples with initial Young´s modulus greater than 1.5 GPa showed no effects due fatigue test loading cycles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20viscoelasticity" title="bone viscoelasticity">bone viscoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20test" title=" fatigue test"> fatigue test</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20relaxation%20test" title=" stress relaxation test"> stress relaxation test</a>, <a href="https://publications.waset.org/abstracts/search?q=trabecular%20bone%20properties" title=" trabecular bone properties"> trabecular bone properties</a> </p> <a href="https://publications.waset.org/abstracts/21146/viscoelastic-characterization-of-bovine-trabecular-bone-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21146.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">489</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> Analysis of Brake System for Vehicle Off-Road</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmo%20Thiago%20Lins%20C%C3%B6uras%20Ford">Elmo Thiago Lins Cöuras Ford</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Alessandra%20Carvalho%20do%20Vale"> Valentina Alessandra Carvalho do Vale</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Ubiragi%20de%20Lima%20Mendes"> José Ubiragi de Lima Mendes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In elapsing of the years it elaborates automobile it is developing automobiles more and more modern that, every year, the vehicles recently of the assembly lines, practically they push for the past produced models there is very little time.

Likewise, fluorographene has also been gaining renown due to its excellent chemical and physical properties which have been mostly applied in the electronics industry. Nevertheless, its tribological properties haven’t been analyzed thoroughly. In this paper, fluorographene was examined as an extreme pressure additive and the nano lubricant made with a cutting fluid and fluorographene in the range of 0.01-0.5% wt, which proved to withstand 53.78% more pounds than the conventional product and 7.12% more than the nano lubricant with graphene in a range between 0.01-0.5% wt. Said extreme pressure test was carried out with a Pin and Vee Block Tribometer following an ASTM D3233A test. The fluorographene used has a low C/F ratio, which reflects a greater presence of atomic fluorine and its low oxygen percentage, supports the substitution of oxygen-containing groups by fluorine. XPS Spectra shows high atomic fluorine content of 56.12%, and SEM analysis details the formation of long and clear crystalline structures, in the fluorographene used. <p
