The comparison takes by reference a set of various indicators that directly or indirectly affect innovation in a positive or negative way. Firstly, a research to obtain the values of each of the indicators was conducted, considering the main primary sources, then, within a set of radial charts is presented the resulting values of each nation and a comparison between them.

These activities, including stores, telephone long distance and local raw materials and energy, and particularly the financial sector, have managed to significantly increase its weight in the flows of FDI in Mexico , however, you should consider whether these trends FDI are positive for the Mexican economy and these activities increase Mexican exports in the medium term , and its share in GDP , gross fixed capital formation and employment. In general stresses that these activities, by far, have been unable to significantly generate linkages with the rest of the economy, a process that has not favored with competitiveness policies and activities aimed at these neutral or horizontal. Since the nineties foreign direct investment (FDI) has shown a remarkable dynamism, both internationally and in Latin America and in Mexico. Only in Mexico the first recipient of FDI in importance in Latin America during 1990-1995 and was displaced by Brazil since FDI increased from levels below 1 % of GDP during the eighties to around 3 % of GDP during the nineties. Its impact has been significant not only from a macroeconomic perspective , it has also allowed the generation of a new industrial production structure and organization, parallel to a significant modernization of a segment of the economy. The case of Mexico also is particularly interesting and relevant because the destination of FDI until 1993 had focused on the purchase of state assets during privatization process. This paper aims to present FDI flows in Mexico and analyze the different business strategies that have been touched and encouraged by the FDI. On the one hand, looking briefly discuss regulatory issues and source and recipient of FDI sectors. Furthermore, the paper presents in more detail the impacts and changes that generated the FDI contribution of FDI in the Mexican economy , besides the macroeconomic context and later legislative changes that resulted in the current regulations is examined around FDI in Mexico, including aspects of the Free Trade Agreement (NAFTA). It is worth noting that foreign investment can not only be considered from the perspective of the receiving economic units. Instead, these flows also reflect the strategic interests of transnational corporations (TNCs) and other companies seeking access to markets and increased competitiveness of their production networks and global distribution, among other reasons. Similarly it is important to note that foreign investment in its various forms is critically dependent on historical and temporal aspects. Thus, the same functionality can vary significantly depending on the specific characteristics of both receptor units as sources of FDI, including macroeconomic, institutional, industrial organization, and social aspects, among others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20direct%20investment%20%28FDI%29" title="foreign direct investment (FDI)">foreign direct investment (FDI)</a>, <a href="https://publications.waset.org/abstracts/search?q=competitiveness" title=" competitiveness"> competitiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=neoliberal%20regime" title=" neoliberal regime"> neoliberal regime</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20domestic%20product%20%28GDP%29" title=" gross domestic product (GDP)"> gross domestic product (GDP)</a>, <a href="https://publications.waset.org/abstracts/search?q=NAFTA" title=" NAFTA"> NAFTA</a>, <a href="https://publications.waset.org/abstracts/search?q=macroeconomic" title=" macroeconomic "> macroeconomic </a> </p> <a href="https://publications.waset.org/abstracts/32728/financial-analysis-of-the-foreign-direct-in-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32728.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">450</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> Enterprise Harmonic Fusion as National Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20R.%20Valencia%20P%C3%A9rez">L.

In this work, we show cosmology, from a perspective that can provide some proposals to help develop SMB in Mexico. We start from the belief that, in a complex world, the solutions to problems must nurture from different approaches. In order to be able to do this, we need to change our point of reference and use theoretical proposals and methodologies that came from other disciplines; in this case, we will try to show that between philosophy and administration exist dialogs that need to be incentivized. The work is structured in three parts. In the first one, we create a description of cosmology and how it could be applied to business. In the second, we show some of the most common problems that the SMB suffer from and in the third, we present a proposal of how cosmology can help improve the development. Finally, we concluded that better understanding of real needs, integration of knowledge at large scale and using information technologies within the cosmology framework presentment could make a difference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=harmonic%20fusion" title="harmonic fusion">harmonic fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20sustainability" title=" national sustainability"> national sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20management" title=" financial management"> financial management</a>, <a href="https://publications.waset.org/abstracts/search?q=triple%20helix" title=" triple helix"> triple helix</a> </p> <a href="https://publications.waset.org/abstracts/69627/enterprise-harmonic-fusion-as-national-sustainability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69627.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">394</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> Greenhouse Gas Emissions from a Tropical Eutrophic Freshwater Wetland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20P.%20Silva">Juan P.

The flux measurements were carried out at four different points using the static chamber technique. CO<sub>2</sub> fluxes ranged from -8270 to 12210 mg.m<sup>-2</sup>.d<sup>-1</sup> (median = 360; SD = 4.11; n = 50), CH<sub>4</sub> ranged between 0.2 and 5270 mg.m<sup>-2</sup>.d<sup>-1</sup> (median = 60; SD = 1.27; n = 45), and N<sub>2</sub>O ranged from -31.12 to 15.4 mg N<sub>2</sub>O m<sup>-2</sup>.d<sup>-1</sup> (median = 0.05; SD = 9.36; n = 42). Although some negative fluxes were observed in the zone dominated by floating plants i.e. <em>Eichornia crassipes, Salvinia </em>sp<em>.</em>, and <em>Pistia stratiotes </em>L., the mean values indicated that the Sonso Lagoon was a net source of CO<sub>2</sub>, CH<sub>4</sub> and N<sub>2</sub>O.

The eutrophication impact on GHG production highlights the necessity to limit the anthropic activities on freshwater wetlands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eutrophication" title="eutrophication">eutrophication</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gas%20emissions" title=" greenhouse gas emissions"> greenhouse gas emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=freshwater%20wetlands" title=" freshwater wetlands"> freshwater wetlands</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a> </p> <a href="https://publications.waset.org/abstracts/43499/greenhouse-gas-emissions-from-a-tropical-eutrophic-freshwater-wetland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43499.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">361</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">134</span> Learning through Gaming with Mobile Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Rodrigo%20Valencia%20P%C3%A9rez">Luis Rodrigo Valencia Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Pe%C3%B1a%20Aguilar"> Juan Manuel Peña Aguilar</a>, <a href="https://publications.waset.org/abstracts/search?q=Adelina%20Morita%20Alexander"> Adelina Morita Alexander</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Lamadrid%20Alvarez"> Alberto Lamadrid Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9ctor%20Fernando%20Valencia%20P%C3%A9rez"> Héctor Fernando Valencia Pérez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Financial education is among the areas of opportunity in the Spanish-speaking from an early age to high school, through mobile devices such as cell phones and tablets using ludic and fun applications like interactive games, children can learn money management and investment through time, thereby fostering the habit of saving and/or sound management of cash and family business resources, having interaction with an uncontrolled environment such as the involvement of other players in the external decisions of the environment in which the game is play.

The above analysis suggests nine dimensions: Expenditure on R & D, intellectual property, appropriate environment to conduct business, economic stability, and triple helix for R & D, ICT Infrastructure, education, human resources and quality of life. Each dimension is represented by an indicator which is later used to construct a radial graph that compares the innovative capacity of the countries analysed. As a result, it is proposed a new indicator of innovation called The Area of Innovation. Observations are made from the results, and finally as a conclusion, those items or dimensions in which Mexico suffers lag in innovation are identify. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dimension" title="dimension">dimension</a>, <a href="https://publications.waset.org/abstracts/search?q=measure" title=" measure"> measure</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20level" title=" innovation level"> innovation level</a>, <a href="https://publications.waset.org/abstracts/search?q=economy" title=" economy"> economy</a>, <a href="https://publications.waset.org/abstracts/search?q=radar%20chart" title=" radar chart"> radar chart</a> </p> <a href="https://publications.waset.org/abstracts/7567/radar-charts-analysis-to-compare-the-level-of-innovation-in-mexico-with-most-innovative-countries-in-triple-helix-schema-economic-and-human-factor-dimension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7567.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">472</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">132</span> Generalization of Tsallis Entropy from a Q-Deformed Arithmetic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Juan%20Pe%C3%B1a">J.

In this work, from a deformation through a scaling function applied to the differential operator, it is possible to generate a q-deformed calculus as well as a q-deformed arithmetic, which not only allows generalizing the exponential and logarithmic functions but also any other standard function. The updated q-deformed differential operator leads to an updated integral operator under which the functions are integrated together with a weight function. For each differentiable function, it is possible to identify its q-deformed partner, which is useful to generalize other algebraic relations proper of the original functions. As an application of this proposal, in this work, a generalization of exponential and logarithmic functions is studied in such a way that their relationship with the thermodynamic functions, particularly the entropy, allows us to have a q-deformed expression of these. As a result, from a particular scaling function applied to the differential operator, a q-deformed arithmetic is obtained, leading to the generalization of the Tsallis entropy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=q-calculus" title="q-calculus">q-calculus</a>, <a href="https://publications.waset.org/abstracts/search?q=q-deformed%20arithmetic" title=" q-deformed arithmetic"> q-deformed arithmetic</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential%20functions" title=" exponential functions"> exponential functions</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20functions" title=" thermodynamic functions"> thermodynamic functions</a> </p> <a href="https://publications.waset.org/abstracts/181635/generalization-of-tsallis-entropy-from-a-q-deformed-arithmetic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181635.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">78</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">131</span> Generalized Hyperbolic Functions: Exponential-Type Quantum Interactions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Juan%20Pe%C3%B1a">Jose Juan Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Morales"> J.

In order to transcend the scope of hyperbolic functions, in this work, a kind of generalized q-deformed hyperbolic functions (g q-dhf) is presented. By a suitable transformation, through the q deformation parameter, it is shown that these g q-dhf can be expressed in terms of their corresponding standard ones besides they can be reduced to the sc q-dhf. As a useful application of the proposed approach, and considering a class of exactly solvable multi-parameter exponential-type potentials, some new q-deformed quantum interactions models that can be used as interesting alternative in quantum physics and quantum states are presented. Furthermore, due that quantum potential models are conditioned on the q-dependence of the parameters that characterize to the exponential-type potentials, it is shown that many specific cases of q-deformed potentials are obtained as particular cases from the proposal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatomic%20molecules" title="diatomic molecules">diatomic molecules</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential-type%20potentials" title=" exponential-type potentials"> exponential-type potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbolic%20functions" title=" hyperbolic functions"> hyperbolic functions</a>, <a href="https://publications.waset.org/abstracts/search?q=q-deformed%20potentials" title=" q-deformed potentials"> q-deformed potentials</a> </p> <a href="https://publications.waset.org/abstracts/82814/generalized-hyperbolic-functions-exponential-type-quantum-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82814.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">184</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">130</span> Peer-Mediated Intervention for Social Communication Difficulties in Adolescents with Autism: Literature Review and Research Recommendations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christine%20L.%20Cole">Christine L.

However, unlike other age and disability groups, there is little intervention research to inform best practice for these students. One evidence-based strategy for younger students with ASD is peer-mediated intervention (PMI). PMI may be particularly promising for use with adolescents, as peers are readily available and natural experts for encouraging authentic high school conversations. This paper provides a review of previous research that evaluated the use of PMI to improve the social-communication skills of students with ASD. Specific intervention features associated with positive student outcomes are identified and recommendations for future research are provided. Adolescents with ASD are targeted due to the critical importance of social conversation at the high school level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism" title="autism">autism</a>, <a href="https://publications.waset.org/abstracts/search?q=peer-mediation" title=" peer-mediation"> peer-mediation</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20communication" title=" social communication"> social communication</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents "> adolescents </a> </p> <a href="https://publications.waset.org/abstracts/24043/peer-mediated-intervention-for-social-communication-difficulties-in-adolescents-with-autism-literature-review-and-research-recommendations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24043.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">470</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> Biosecurity Control Systems in Two Phases for Poultry Farms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Pe%C3%B1a%20Aguilar%20Juan">M.

The control system consists of two phases for the conditioning of the farm during the sanitary break. In the first phase, viral and bacterial inactivation was performed by treating the stool dry cleaning, along with the development of a specialized product that foster the generation of temperatures above 55 °C in less than 24 hr, for virus inactivation. In the second phase, a process for disinfection by fogging was implemented, along with the development of a specialized disinfectant that guarantee no risk for the operators’ health or birds. As a result of this process, it was possible to minimize the level of mortality of chickens on farms from 12% to 5.49%, representing a reduction of 6.51% in the death rate, through the formula applied to the treatment of poultry litter based on oxidising agents used as antiseptics, hydrogen peroxide solutions, glacial acetic acid and EDTA in order to act on bacteria, viruses, micro bacteria and spores. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation" title="innovation">innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=triple%20helix" title=" triple helix"> triple helix</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20farms" title=" poultry farms"> poultry farms</a>, <a href="https://publications.waset.org/abstracts/search?q=biosecurity" title=" biosecurity"> biosecurity</a> </p> <a href="https://publications.waset.org/abstracts/53145/biosecurity-control-systems-in-two-phases-for-poultry-farms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53145.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">284</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> Proposing Problem-Based Learning as an Effective Pedagogical Technique for Social Work Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christine%20K.%20Fulmer">Christine K.

There is an expectation that graduates of social work programs throughout the world are to be prepared to practice at a level of competence, which is beneficial to both the well-being of individuals and community. Experiential learning is one way to prepare students for competent practice. The use of Problem-Based Learning (PBL) is a form experiential education that has been successful in a number of disciplines to bridge the gap between the theoretical concepts in the classroom to the real world. PBL aligns with the constructivist theoretical approach to learning, which emphasizes the integration of new knowledge with the beliefs students already hold. In addition, the basic tenants of PBL correspond well with the practice behaviors associated with social work practice including multi-disciplinary collaboration and critical thinking. This paper makes an argument for utilizing PBL in social work education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20work%20education" title="social work education">social work education</a>, <a href="https://publications.waset.org/abstracts/search?q=problem-based%20learning" title=" problem-based learning"> problem-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=experiential%20learning" title=" experiential learning"> experiential learning</a>, <a href="https://publications.waset.org/abstracts/search?q=constructivist%20theoretical%20approach" title=" constructivist theoretical approach"> constructivist theoretical approach</a> </p> <a href="https://publications.waset.org/abstracts/67887/proposing-problem-based-learning-as-an-effective-pedagogical-technique-for-social-work-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67887.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">314</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> Liver Lesion Extraction with Fuzzy Thresholding in Contrast Enhanced Ultrasound Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abder-Rahman%20Ali">Abder-Rahman Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ad%C3%A9la%C3%AFde%20Albouy-Kissi"> Adélaïde Albouy-Kissi</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Grand-Brochier"> Manuel Grand-Brochier</a>, <a href="https://publications.waset.org/abstracts/search?q=Viviane%20Ladan-Marcus"> Viviane Ladan-Marcus</a>, <a href="https://publications.waset.org/abstracts/search?q=Christine%20Hoeffl"> Christine Hoeffl</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude%20Marcus"> Claude Marcus</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Vacavant"> Antoine Vacavant</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Yves%20Boire"> Jean-Yves Boire</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a new segmentation approach for focal liver lesions in contrast enhanced ultrasound imaging.

We examined Republicans' and Democrats’ attitudes about police reform policy during the 2020 racial justice protests and calls to ‘defund the police’. We hypothesized that a) Republicans and Democrats will be polarized on the “defund police'' question; however, b) they will have similar overall attitudes towards specific police reform policies (will be on the same side of the scale--disagree vs. agree), but c) will differ in their extent of agreement or disagreement (main effect of political party ID, but located on the same side of the scale). Using one-way, Multivariate analysis of covariance (MANCOVA) controlling for race, education, and income, we found an overall effect of political party ID. Six out of the nine policies studied were, in fact, not polarizing; both groups were in consensus on whether they disagreed or agreed with the policy, including “defund police''.

They are a rare cause of an umbilical mass, with very few cases previously reported following abdominal surgery. These lesions can present with a range of symptoms, including palpable mass, pain, redness, or discharge. This paper reports a case of an umbilical epidermal inclusion cyst in a 52-year-old female presenting with a six-week history of a painful, red umbilical lump on a background of two previous diagnostic laparoscopies. Abdominal computed tomography (CT) scans revealed non-specific soft tissue thickening in the umbilical region. This was successfully treated with complete excision of the lesion. Umbilical lumps are a common presentation but can represent a diagnostic challenge. The differential diagnosis should include an epidermal inclusion cyst, particularly in a patient who has had previous abdominal surgery, including laparoscopic surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epidermal%20inclusion%20cyst" title="epidermal inclusion cyst">epidermal inclusion cyst</a>, <a href="https://publications.waset.org/abstracts/search?q=laparoscopy" title=" laparoscopy"> laparoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilical%20mass" title=" umbilical mass"> umbilical mass</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilicus" title=" umbilicus"> umbilicus</a> </p> <a href="https://publications.waset.org/abstracts/138636/umbilical-epidermal-inclusion-cysts-a-rare-cause-of-umbilical-mass-a-case-report-and-review-of-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138636.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">83</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> Math Anxiety Effects on Complex Addition: An ERP Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Isabel%20N%C3%BA%C3%B1ez-Pe%C3%B1a">María Isabel Núñez-Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=Macarena%20Su%C3%A1rez%20Pellicioni"> Macarena Suárez Pellicioni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, we used event-related potentials (ERP) to address the question of whether high (HMA) and low math-anxious (LMA) individuals differ on a complex addition verification task, which involved both carrying and non-carrying additions. ERPs were recorded while seventeen HMA and seventeen LMA individuals performed the verification task. Groups did not differ in trait anxiety or gender distribution. Participants were presented with two-digit additions and were asked to decide whether the proposed solution was correct or incorrect. Behavioral data showed a significant Carrying x Proposed solution x Group interaction for accuracy, showing that carrying additions were more error prone than non-carrying ones for both groups, although the difference non-carrying minus carrying was larger for the HMA group. As for ERPs, a P2 component larger in HMA individuals than in their LMA peers was found both for carrying and non-carrying additions. The P2 was followed by a sustained negative slow wave at parietal positions. Because the negative slow waves are thought to reflect the updating of working memory, these results give support to the relationship among working memory, math performance and math anxiety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=math%20anxiety" title="math anxiety">math anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=carrying" title=" carrying"> carrying</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory" title=" working memory"> working memory</a>, <a href="https://publications.waset.org/abstracts/search?q=P2" title=" P2 "> P2 </a> </p> <a href="https://publications.waset.org/abstracts/25642/math-anxiety-effects-on-complex-addition-an-erp-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25642.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">447</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> Two-Phase Flow Modelling and Numerical Simulation for Waterflooding in Enhanced Oil Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pe%C3%B1a%20A.%20Roland%20R.">Peña A.

This paper shows the importance of the role of the numerical modelling of waterflooding and how to provide a better description of the fluid flow during this process. The mathematical model is based on the mass conservation equations for the oil and water phases. Rock compressibility and capillary pressure equations are coupled to the mathematical model. For discretizing and linearizing the partial differential equations, we used the Finite Volume technique and the Newton-Raphson method, respectively. The results of three scenarios for waterflooding in porous media are shown. The first scenario was estimating the water saturation in the media without rock compressibility and without capillary pressure. The second scenario was estimating the front of the water considering the rock compressibility and capillary pressure. The third case is to compare different fronts of water saturation for three fluids viscosity ratios without and with rock compressibility and without and with capillary pressure. Results of the simulation indicate that the rock compressibility and the capillary pressure produce changes in the pressure profile and saturation profile during the displacement of the oil for the water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capillary%20pressure" title="capillary pressure">capillary pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20compressibility" title=" rock compressibility"> rock compressibility</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a> </p> <a href="https://publications.waset.org/abstracts/148309/two-phase-flow-modelling-and-numerical-simulation-for-waterflooding-in-enhanced-oil-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148309.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">124</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">122</span> Synthesis of Iron-Modified Montmorillonite as Filler for Electrospun Nanocomposite Fibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khryslyn%20Ara%C3%B1o">Khryslyn Araño</a>, <a href="https://publications.waset.org/abstracts/search?q=Dela%20Cruz"> Dela Cruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Leo"> Michael Leo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dela%20Pena"> Dela Pena</a>, <a href="https://publications.waset.org/abstracts/search?q=Eden%20May"> Eden May</a>, <a href="https://publications.waset.org/abstracts/search?q=Leslie%20Joy%20Diaz"> Leslie Joy Diaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Montmorillonite (MMT) is a very abundant clay mineral and is versatile such that it can be chemically or physically altered by changing the ions between the sheets of its layered structure. This clay mineral can be prepared into functional nanoparticles that can be used as fillers in other nanomaterials such as nanofibers to achieve special properties. In this study, two types of iron-modified MMT, Iron-MMT (FeMMT) and Zero Valent Iron-MMT (ZVIMMT) were synthesized via ion exchange technique. The modified clay was incorporated in polymer nanofibers which were produced using a process called electrospinning. ICP analysis confirmed that clay modification was successful where there is an observed decrease in the concentration of Na and an increase in the concentration of Fe after ion exchange. XRD analysis also confirmed that modification took place because of the changes in the d-spacing of Na-MMT from 11.5 Å to 13.6 Å and 12.6 Å after synthesis of FeMMT and ZVIMMT, respectively. SEM images of the electrospun nanofibers revealed that the ZVIMMT-filled fibers have a smaller average diameter than the FeMMT-filled fibers because of the lower resistance of the suspensions of the former to the elongation force from the applied electric field. The resistance to the electric field was measured by getting the bulk voltage of the suspensions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20science" title=" materials science"> materials science</a> </p> <a href="https://publications.waset.org/abstracts/8295/synthesis-of-iron-modified-montmorillonite-as-filler-for-electrospun-nanocomposite-fibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8295.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">345</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> A Comparison of the Adsorption Mechanism of Arsenic on Iron-Modified Nanoclays</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Leo%20L.%20Dela%20Cruz">Michael Leo L.

A comparative study on the adsorption mechanism of arsenic on iron modified nanoclays was undertaken. Iron intercalated montmorillonite (Fe-MMT) and montmorillonite supported zero-valent iron (ZVI-MMT) were the adsorbents investigated in this study. Fe-MMT was produced through ion-exchange by replacing the sodium intercalated ions in montmorillonite with iron (III) ions. The iron (III) in Fe-MMT was later reduced to zero valent iron producing ZVI-MMT. Adsorption study was performed by batch technique. Obtained data were fitted to intra-particle diffusion, pseudo-first order, and pseudo-second-order models and the Elovich equation to determine the kinetics of adsorption. The adsorption of arsenic on Fe-MMT followed the intra-particle diffusion model with intra-particle rate constant of 0.27 mg/g-min0.5. Arsenic was found to be chemically bound on ZVI-MMT as suggested by the pseudo-second order and Elovich equation. The derived pseudo-second order rate constant was 0.0027 g/mg-min with initial adsorption rate computed from the Elovich equation was 113 mg/g-min. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20mechanism" title="adsorption mechanism">adsorption mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic" title=" arsenic"> arsenic</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20valent%20iron" title=" zero valent iron"> zero valent iron</a> </p> <a href="https://publications.waset.org/abstracts/9758/a-comparison-of-the-adsorption-mechanism-of-arsenic-on-iron-modified-nanoclays" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9758.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">415</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> Education for Sustainability Using PBL on an Engineering Course at the National University of Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hern%C3%A1n%20G.%20Cort%C3%A9s-Mora">Hernán G.

Firstly, we present a literature review on the education for sustainability field, emphasizing the skills and knowledge areas required for its development, as well as the commitment of the Faculty of Engineering of the Universidad Nacional de Colombia, and other engineering faculties of the country, regarding education for sustainability. This article covers the general aspects of the course, describes how students team were formed, and how their experience was during the first semester of 2017. During this period two groups of students decided to develop their course project aiming to solve a problem regarding a Non-Governmental Organization (NGO) that works with head-of-household mothers in a low-income neighborhood in Bogota (Colombia). Subsequently, we show how sustainability is involved in the course, how tools are provided to students, and how activities are developed as to strengthen their abilities, which allows them to incorporate sustainability in their projects while also working on the methodology used to develop said projects. Finally, we introduce the results obtained by the students who sent the prototypes of their projects to the community they were working on and the conclusions reached by them regarding the course experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainability" title="sustainability">sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=project-based%20learning" title=" project-based learning"> project-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20%20education" title=" engineering education"> engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education%20for%20sustainability" title=" higher education for sustainability"> higher education for sustainability</a> </p> <a href="https://publications.waset.org/abstracts/69628/education-for-sustainability-using-pbl-on-an-engineering-course-at-the-national-university-of-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69628.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">351</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> Mechanical Properties, Vibrational Response and Flow-Field Analysis of Staghorn Coral Skeleton, Acropora cervicornis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alejandro%20Carrasco-Pena">Alejandro Carrasco-Pena</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Omer"> Mahmoud Omer</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Orlovskaya"> Nina Orlovskaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The results of studies of microstructure, mechanical behavior, vibrational response, and flow field analysis of critically endangered staghorn coral (Acropora cervicornis) skeletons are reported. The CaCO₃ aragonite structure of a chemically-cleaned coral skeleton of A. cervicornis was studied by optical microscopy and computer tomography. The mechanical behavior was studied using uniaxial compression and Vickers hardness technique. The average maximum stress measured during skeleton uniaxial compression was 10.7 ± 2.24 MPa and Vickers hardness was 3.56 ± 0.31 GPa. The vibrational response of the aragonite structure was studied by micro-Raman spectroscopy, which showed a substantial dependence of the structure on applied compressive stress. The flow-field around a single coral skeleton forming vortices in the wake of the moving skeleton was measured using Particle Image Velocimetry (PIV). The results are important for further analysis of time-dependent mechanical fatigue behavior and predicting the lifetime of staghorn corals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure" title="failure">failure</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20spectroscopy" title=" Raman spectroscopy"> Raman spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/108257/mechanical-properties-vibrational-response-and-flow-field-analysis-of-staghorn-coral-skeleton-acropora-cervicornis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108257.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">155</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">118</span> Measuring the Effectiveness of Response Inhibition regarding to Motor Complexity: Evidence from the Stroop Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Germ%C3%A1n%20G%C3%A1lvez-Garc%C3%ADa">Germán Gálvez-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Lavin"> Marta Lavin</a>, <a href="https://publications.waset.org/abstracts/search?q=Javiera%20Pe%C3%B1a"> Javiera Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Albayay"> Javier Albayay</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Bascour"> Claudio Bascour</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesus%20Fernandez-Gomez"> Jesus Fernandez-Gomez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicia%20P%C3%A9rez-G%C3%A1lvez"> Alicia Pérez-Gálvez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We studied the effectiveness of response inhibition in movements with different degrees of motor complexity when they were executed in isolation and alternately.

Repeated measures ANOVAs were used to compare reaction time, movement time, kinematic errors and Movement errors across conditions (experimental block, movement, and congruency). Delta plots were constructed to perform distributional analyses of response inhibition and accuracy rate. The effectiveness of response inhibition did not show difference when the movements were performed in separated blocks. Nevertheless, it showed differences when they were performed alternately in the same experimental block, being more effective for the lifting action.

The results revealed that the tourists agree that the local establishments offering local cuisines are accessible in terms of the location, internet visibility and facilities for persons-with-disabilities. The tourist are also willing to pay for the local food because it is attainable, budget-friendly, worthy for an expensive price, satisfies the cravings, reflects the physical appearance of the establishment and its quantity is reasonable based on the price. However, the tourists disagree that the local food completes their overall experience as tourists and it does not have the potential to satisfy all types of tourists.

As part of the results, post-surgical follow-up is included as an instrument to verify the patient's recovery and the validity of the procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surgical%20planning" title="surgical planning">surgical planning</a>, <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=rapid%20prototyping" title=" rapid prototyping"> rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20deposition%20modeling" title=" fused deposition modeling"> fused deposition modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=custom%20anatomical%20model" title=" custom anatomical model"> custom anatomical model</a> </p> <a href="https://publications.waset.org/abstracts/163905/surgical-planning-for-the-removal-of-cranial-spheno-orbital-meningioma-by-using-personalized-polymeric-prototypes-obtained-with-additive-manufacturing-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163905.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">100</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">115</span> Comprehensive Approach to Enhance Green Buildings in Urban Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Pena">M.

Green growth policies, as a system, targets to satisfy two main needs: economic and environmental growth. Cities are complex systems composed of varied characteristics such as differences in socio-environmental conditions and local affordability, among others. Thus, commissioned policies are required to address these differences and to ensure green development. A more maintainable and justifiable, resource-efficient green growth can be obtained in urban areas if multi-criteria framework of policies relevant to green buildings is designed. Reason is that, this approach fits to target the differences and unique conditions of urban areas. By following the principles of axiomatic design, this paper urges to derive a framework for the application of green buildings policies in urban areas with distinctive socio-economic and environmental characteristics. Functional requirements defined as principles to ensure green growth and design parameters are identified in each set of conditions. Design matrices are constructed for each group of urban areas. Thus, the understanding of the needs and differences for each group of urban areas and the methodology to ensure green buildings is achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axiomatic%20design" title="axiomatic design">axiomatic design</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20growth" title=" green growth"> green growth</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20planning" title=" urban planning"> urban planning</a> </p> <a href="https://publications.waset.org/abstracts/10651/comprehensive-approach-to-enhance-green-buildings-in-urban-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10651.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">352</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">114</span> Acclimatation of Bacterial Communities for Biohydrogen Production by Co-Digestion Process in Batch and Continuous Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%B3mez%20Romero%20Jacob">Gómez Romero Jacob</a>, <a href="https://publications.waset.org/abstracts/search?q=Garc%C3%ADa%20Pe%C3%B1a%20Elvia%20In%C3%A9s"> García Peña Elvia Inés</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The co-digestion process of crude cheese whey (CCW) with fruit vegetable waste (FVW) for biohydrogen production was investigated in batch and continuous systems, in stirred 1.8 L bioreactors at 37°C. Five different C/N ratios (7, 17, 21, 31, and 46) were tested in batch systems. While, in continuous system eight conditions were evaluated, hydraulic retention time (from 60 to 10 h) and organic load rate (from 21.96 to 155.87 g COD/L d). Data in batch tests showed a maximum specific biohydrogen production rate of 10.68 mmol H2/Lh and a biohydrogen yield of 449.84 mL H2/g COD at a C/N ratio of 21. In continuous co-digestion system, the optimum hydraulic retention time and organic loading rate were 17.5 h and 80.02 g COD/L d, respectively. Under these conditions, the highest volumetric production hydrogen rate (VPHR) and hydrogen yield were 11.02 mmol H2/L h, 800 mL H2/COD, respectively. A pyrosequencing analysis showed that the main acclimated microbial communities for co-digestion studies consisted of Bifidobacterium, with 85.4% of predominance. Hydrogen producing bacteria such as Klebsiella (9.1%), Lactobacillus (0.97%), Citrobacter (0.21%), Enterobacter (0.27%), and Clostridium (0.18%) were less abundant at this culture period. The microbial population structure was correlated with the lactate, acetate, and butyrate profiles obtained. Results demonstrated that the co-digestion of CCW with FVW improves biohydrogen production due to a better nutrient balance and improvement of the system’s buffering capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acclimatation" title="acclimatation">acclimatation</a>, <a href="https://publications.waset.org/abstracts/search?q=biohydrogen" title=" biohydrogen"> biohydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=co-digestion" title=" co-digestion"> co-digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20community" title=" microbial community"> microbial community</a> </p> <a href="https://publications.waset.org/abstracts/19282/acclimatation-of-bacterial-communities-for-biohydrogen-production-by-co-digestion-process-in-batch-and-continuous-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19282.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">556</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">113</span> Electoral Mathematics and Asymmetrical Treatment to Political Parties: The Mexican Case</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ver%C3%B3nica%20Arredondo">Verónica Arredondo</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Mart%C3%ADnez-Panero"> Miguel Martínez-Panero</a>, <a href="https://publications.waset.org/abstracts/search?q=Teresa%20Pe%C3%B1a"> Teresa Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoriano%20Ram%C3%ADrez"> Victoriano Ramírez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Mexican Chamber of Deputies is composed of 500 representatives: 300 of them elected by relative majority and another 200 ones elected through proportional representation in five electoral clusters (constituencies) with 40 representatives each. In this mixed-member electoral system, the seats distribution of proportional representation is not independent of the election by relative majority, as it attempts to correct representation imbalances produced in single-member districts. This two-fold structure has been maintained in the successive electoral reforms carried out along the last three decades (eight from 1986 to 2014). In all of them, the election process of 200 seats becomes complex: Formulas in the Law are difficult to understand and to be interpreted. This paper analyzes the Mexican electoral system after the electoral reform of 2014, which was applied for the first time in 2015. The research focuses on contradictions and issues of applicability, in particular situations where seats allocation is affected by ambiguity in the law and where asymmetrical treatment of political parties arises. Due to these facts, a proposal of electoral reform will be presented. It is intended to be simpler, clearer, and more enduring than the current system. Furthermore, this model is more suitable for producing electoral outcomes free of contradictions and paradoxes. This approach would allow a fair treatment of political parties and as a result an improved opportunity to exercise democracy. <p class="card-text"><strong>Keywords:</strong> <a
