identification, ensuring the safety and sustainability of urban infrastructure. Comprehensive studies involving seismic hazard, vulnerability, and exposure evaluations are pivotal for estimating potential losses and guiding proactive measures against seismic events. However, broad-scale traditional risk studies limit consideration of specific local threats and identify vulnerable housing within a structural typology. Achieving precise results at neighbourhood levels demands higher resolution seismic hazard exposure, and vulnerability studies. This research aims to bolster sustainability and safety against seismic disasters in three Central American and Caribbean capitals. It integrates geospatial techniques and artificial intelligence into seismic risk studies, proposing cost-effective methods for exposure data collection and damage prediction. The methodology relies on prior seismic threat studies in pilot zones, utilizing existing exposure and vulnerability data in the region. Emphasizing detailed building attributes enables the consideration of behaviour modifiers affecting seismic response. The approach aims to generate detailed risk scenarios, facilitating prioritization of preventive actions pre-, during, and post-seismic events, enhancing decision-making certainty. Detailed risk scenarios necessitate substantial investment in fieldwork, training, research, and methodology development. Regional cooperation becomes crucial given similar seismic threats, urban planning, and construction systems among involved countries. The outcomes hold significance for emergency planning and national and regional construction regulations. The success of this methodology depends on cooperation, investment, and innovative approaches, offering insights and lessons applicable to regions facing moderate seismic threats with vulnerable constructions. Thus, this framework aims to fortify resilience in seismic-prone areas and serves as a reference for global urban planning and disaster management strategies. In conclusion, this research proposes a comprehensive framework for seismic risk assessment in high-risk urban areas, emphasizing detailed studies at finer resolutions for precise vulnerability evaluations. The approach integrates regional cooperation, geospatial technologies, and adaptive fragility curve adjustments to enhance risk assessment accuracy, guiding effective mitigation strategies and emergency management plans. <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=behaviour%20modifiers" title=" behaviour modifiers"> behaviour modifiers</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20management" title=" emergency management"> emergency management</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20strategies" title=" mitigation strategies"> mitigation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/179498/enhancing-seismic-resilience-in-urban-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179498.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">68</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">321</span> Developing a Model – an Application of Fuzzy Analytic Network Process Techniques for Hostels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pin-Ju%20Juan">Pin-Ju Juan</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng-Yu%20Juan"> Peng-Yu Juan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Shan%20Chen"> Yi-Shan Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this paper is to present a fuzzy Analytic Network Process (ANP) model for the hostel organizational performance selection.

The aim of this study was to examine web management strategies to ensure the availability of resources and services in telemedicine so as to provide medical information management with an accessible strategy. In addition, to evaluate the quality-of-service parameters, the followings were measured: delays, throughput, jitter, latency, available bandwidth, percent of access and denial of services based of web management performance map with profiles permissions and database management. Through 24 different test scenarios, the results show 100% in availability of medical information, in relation to access of medical staff to web services, and quality of service (QoS) of 99% because of network delay and performance of computer network. The findings of this study suggest that the proposed strategy of web management is an ideal solution to guarantee the availability, reliability, and accessibility of medical information. Finally, this strategy offers seven user profile used at telemedicine center of Bogota-Colombia keeping QoS parameters suitable to telemedicine services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=availability" title="availability">availability</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20information" title=" medical information"> medical information</a>, <a href="https://publications.waset.org/abstracts/search?q=QoS" title=" QoS"> QoS</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=telemedicine" title=" telemedicine"> telemedicine</a> </p> <a href="https://publications.waset.org/abstracts/99707/availability-strategy-of-medical-information-for-telemedicine-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99707.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">205</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">317</span> N Doped Multiwall Carbon Nanotubes Growth over a Ni Catalyst Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angie%20Quevedo">Angie Quevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Bussi"> Juan Bussi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nestor%20Tancredi"> Nestor Tancredi</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Fajardo-D%C3%ADaz"> Juan Fajardo-Díaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Florentino%20L%C3%B3pez-Ur%C3%ADas"> Florentino López-Urías</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilio%20Mu%C3%B1%C3%B3z-Sandoval"> Emilio Muñóz-Sandoval</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we study the carbon nanotubes (CNTs) formation by catalytic chemical vapor deposition (CCVD) over a catalyst with 20 % of Ni supported over La₂Zr₂O₇ (Ni20LZO). The high C solubility of Ni made it one of the most used in CNTs synthesis. Nevertheless, Ni presents also sintering and coalescence at high temperature. These troubles can be reduced by choosing a suitable support. We propose La₂Zr₂O₇ as for this matter since the incorporation of Ni by co-precipitation and calcination at 900 °C allows a good dispersion and interaction of the active metal (in the oxidized form, NiO) with this support. The CCVD was performed using 1 g of Ni20LZO at 950 °C during 30 min in Ar:H₂ atmosphere (2.5 L/min). The precursor, benzylamine, was added by a nebulizer-sprayer. X ray diffraction study shows the phase separation of NiO and La₂Zr₂O₇ after the calcination and the reduction to Ni after the synthesis. Raman spectra show D and G bands with a ID/IG ratio of 0.75. Elemental study verifies the incorporation of 1% of N. Thermogravimetric analysis shows the oxidation process start at around 450 °C. Future studies will determine the application potential of the samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=N%20doped%20carbon%20nanotubes" title="N doped carbon nanotubes">N doped carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=catalytic%20chemical%20vapor%20deposition" title=" catalytic chemical vapor deposition"> catalytic chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20catalyst" title=" nickel catalyst"> nickel catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=bimetallic%20oxide" title=" bimetallic oxide"> bimetallic oxide</a> </p> <a href="https://publications.waset.org/abstracts/125152/n-doped-multiwall-carbon-nanotubes-growth-over-a-ni-catalyst-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125152.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">316</span> The Impact of COVID-19 Pandemic on the Issue and Ideological Congruence of Trump and Bolsonaro Administrations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Contrera">Flavio Contrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Cesar%20Gregorio"> Paulo Cesar Gregorio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent political developments and government control actions in the face of the COVID-19 pandemic draw attention to the contrast between the duties of government and the demands of democratic representation. Elected by mobilizing far-right issues, Trump and Bolsonaro moved away from the WHO guidelines but had to accommodate demands on the health and on the social protection system on the one hand and demands from the economic sector on the other. This study used the MARPOR Project method to assess the impact of the COVID-19 pandemic on the issue and ideological congruence between the electoral and governmental arena in both the Trump and Bolsonaro Administrations. Findings reveal issue congruence between arenas in "National Way of Life: Positive", "Law and Order," and "Technology and Infrastructure" for Donald Trump, and "Welfare State Expansion" for Bolsonaro. Ideological estimation results show that Trump and Bolsonaro positioned to the right in their presidential elections, initially moved to the center-right. However, welfare policies actions at high frequency during the COVID-19 pandemic moved the ideological estimations of both governments to the center-left, despite their denial rhetoric. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congruence" title="congruence">congruence</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=Donald%20Trump" title=" Donald Trump"> Donald Trump</a>, <a href="https://publications.waset.org/abstracts/search?q=Jair%20Bolsonaro" title=" Jair Bolsonaro"> Jair Bolsonaro</a> </p> <a href="https://publications.waset.org/abstracts/142854/the-impact-of-covid-19-pandemic-on-the-issue-and-ideological-congruence-of-trump-and-bolsonaro-administrations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142854.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">231</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">315</span> Prevalence and Characteristics of Consumption of Nutraceuticals: The Case Study of Undergraduate Students of Medellin- Colombia, 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez">Gloria Inés Martínez Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Guillermo%20Jim%C3%A9nez%20Jim%C3%A9nez"> Juan Guillermo Jiménez Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Sebasti%C3%A1n%20Lopera%20Valle"> Johan Sebastián Lopera Valle</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rojas%20Jim%C3%A9nez"> Sara Rojas Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Uribe%20Ocampo"> Alejandra Uribe Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Correa%20P%C3%A9rez"> Sara Correa Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Mar%C3%ADn%20C%C3%A1rdenas"> Juan Sebastián Marín Cárdenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals. Objective: To determine the prevalence and characteristics of consumption of nutraceuticals in undergraduate students. Methodology: Cross-sectional study. It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.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">577</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">314</span> Hydrodeoxygenation of Furfural over RU Sub-Nano Particles Supported on Al₂O₃-SIO₂ Mixed Oxides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaima%20Zoulikha%20Tabet%20Zatla">Chaima Zoulikha Tabet Zatla</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihel%20Dib"> Nihel Dib</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumeya%20Bedrane"> Sumeya Bedrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Hernandez%20Garrido"> Juan Carlos Hernandez Garrido</a>, <a href="https://publications.waset.org/abstracts/search?q=Redouane%20Bachir"> Redouane Bachir</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Angel%20Cauqui"> Miguel Angel Cauqui</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Juan%20Calvino%20Gamez"> Jose Juan Calvino Gamez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> These last year's our planet has witnessed global warming, which is a serious threat to our lives; it has many causes, such as the CO₂ excess in the atmosphere that results from our activity, for the purpose of living in a neater and better environment, working and improving an eco-responsible energy system is a must. Valorization of biomass to produce biofuels is among the most compelling routes to decrease air pollution without considerable modification in current vehicle technology. Effective transformation of lignocellulosic biomass-derived compounds into liquid fuels and value-added chemicals is an economically viable solution. Presently, very competitive technics for the conversion of lignocellulosic biomass into platform chemicals, such as furfural and Hydroxymethylfurfural (HMF), are used. Furfural (C₅H₄O₂) is a major hemi cellulosic biomass-derived platform molecule. In our work, we focus on the valorization of lignocellulosic biomass derivative furfural that is transformed into biofuel through a hydrodeoxygenation reaction in general and involving a catalytic process. In order to get to this point, we are synthesizing and characterizing a series of catalysts with different amounts of Ru (0.5%, 1% and 2%) supported on alumina-silica mixed oxides with various molar ratios (Si/Al = 2.5; 5; 7; 10; 15). These catalysts will be characterized by numerous technics such as N₂ adsorption/desorption, Pyridine adsorption (acidity measure), FTIR, X-rays diffraction, AAS, TEM and SEM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=furfural" title="furfural">furfural</a>, <a href="https://publications.waset.org/abstracts/search?q=ruthenium" title=" ruthenium"> ruthenium</a>, <a href="https://publications.waset.org/abstracts/search?q=silica-alumina" title=" silica-alumina"> silica-alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuel" title=" biofuel"> biofuel</a> </p> <a href="https://publications.waset.org/abstracts/163321/hydrodeoxygenation-of-furfural-over-ru-sub-nano-particles-supported-on-al2o3-sio2-mixed-oxides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163321.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">84</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">313</span> Microscopic Visualization of the Ice Slurry Ice Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jos%C3%A9%20Mil%C3%B3n%20Guzm%C3%A1n">Juan José Milón Guzmán</a>, <a href="https://publications.waset.org/abstracts/search?q=Herbert%20Jes%C3%BAs%20Del%20Carpio%20Beltr%C3%A1n"> Herbert Jesús Del Carpio Beltrán</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Leal%20Braga"> Sergio Leal Braga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Visualizations of ice particles of ice slurry are performed.

Twenty-four hybrids lactating sows (Landrace x Yorkshire) were divided into three treatments with eight sows per treatment. On day 107 of gestation, the sows were moved to the mesh floor maternity cages in an environment regulated by the environment regulated (2.4 × 0.6 m) contained an area (2.4 × 0.5 m) for newborn pigs on each side, all diets were provided as a dry powder, and the sows received free access to water throughout the experimental period. After farrowing, the sows were fasted for 12 hours, the daily feed ration gradually increased, and the sows had ad libitum access to feed on the fourth day. The diets used were corn-soybean meal-based, containing 0 (CONT), recycled vegetable oil 1.0 % (RVOL), or recycled vegetable oil 1.5 % (RVOH) for 30 days. The diets contained similar calculated levels of crude protein and metabolizable energy and contained vitamins and minerals that exceeded National Research Council (1998) recommendations; sows were fed three times daily. On day 30, piglets were weaned, and performances of lactating sows and nursery piglets were recorded. Results indicated that average daily feed intake (5.58, 5.55, and 5.49 kg for CONT, RVOL, and RVO, respectively) of sows were not affected (P > 0.05) by different dietary. There was no difference in the average body weight of piglets on the day of birth, with 1.33, 1.36, and 1.35 kg, respectively (P > 0.05). There was no difference in average body weight of piglets on day 30, with 6.91, 6.75, and 7.05 kg, respectively 0.05) between treatments numbers of weaned piglets per sow (9.95, 9.80, and 9.80) were not affected by treatments (P > 0.05).In conclusion, the substitution of virgin vegetable oil for recycled vegetable oil in the diet does not affect the productive performance of lactating sows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lactating" title="lactating">lactating</a>, <a href="https://publications.waset.org/abstracts/search?q=sow" title=" sow"> sow</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetable" title=" vegetable"> vegetable</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil"> oil</a> </p> <a href="https://publications.waset.org/abstracts/142975/use-of-recycled-vegetable-oil-in-the-diet-of-lactating-sows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142975.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">300</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">310</span> Ideology and Lexicogrammar: Discourse Against the Power in Lyrical Texts (XIII, XVII and XX Centuries)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ulisses%20Tadeu%20Vaz%20de%20Oliveira">Ulisses Tadeu Vaz de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of multifunctional studies in the theoretical-methodological perspective of the Systemic-Functional Grammar (SFG) and the increasing number of critical literary studies have introduced new opportunities for the study of ideologies and societies, but also brought up new challenges across and within many areas. In this regard, the Critical Linguistics researches allow a form of pairing a textual linguistic analysis method (micro level) with a social language theory in political and ideological processes (macro level), presented in the literature. This presentation will report on strategies to criticize power holders in literary productions from three distinct eras, namely: (a) Satirical Galego-Portuguese chants of Gil Pérez Conde (thirteenth century), (b) Poems of Gregorio de Matos Guerra (seventeenth century), and (c) Songs of Chico Buarque de Holanda (twentieth century). The analysis of these productions is based on the SFG proposals, which considers the clause as a social event. Therefore, the structure serves to realize three concurrent meanings (metafunctions): Ideational, Interpersonal and Textual. The presenter aims to shed light on the core issues relevant to the successes of the authors to criticize authorities in repressive times while caring about face-threatening and politeness. The effective and meaningful critical discourse was a way of moving the society`s chains towards new ideologies reflected in the lexicogrammatical choices made and the rhetorical functions of the persuasive structures used by the authors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ideology" title="ideology">ideology</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=persuasion" title=" persuasion"> persuasion</a>, <a href="https://publications.waset.org/abstracts/search?q=systemic-functional%20grammar" title=" systemic-functional grammar"> systemic-functional grammar</a> </p> <a href="https://publications.waset.org/abstracts/31516/ideology-and-lexicogrammar-discourse-against-the-power-in-lyrical-texts-xiii-xvii-and-xx-centuries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31516.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">418</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">309</span> Model of Cosserat Continuum Dispersion in a Half-Space with a Scatterer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Velez">Francisco Velez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20David%20Gomez"> Juan David Gomez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dispersion effects on the Scattering for a semicircular canyon in a micropolar continuum are analyzed, by using a computational finite element scheme.

Nursing personnel at the health center completed a computerized case investigation form that was translated, adapted, and modified from CDC’s Patient Under Investigation (PUI) Form. Between July 13, 2020, and March 17, 2022, a total of 9,233 SARS-CoV-2 tests were conducted at the health center, 16.9% of which were classified as confirmed cases (positive molecular test) and 27.7% as probable cases (positive serologic test). Most of the confirmed cases were females (60.0%), under 20 years old (29.1%), and living in their homes (59.1%). In the 14 days before the onset of symptoms, 26.3% of confirmed cases reported going to the supermarket, 22.4% had contact with a known COVID-19 case, and 20.7% went to work. The symptoms most commonly reported were sore throat (33.4%), runny nose (33.3%), cough (24.9%), and headache (23.2%). The most common preexisting medical conditions among confirmed cases were hypertension (19.3%), chronic lung disease including asthma, emphysema, COPD (13.3%), and diabetes mellitus (12.8). Multiple logistic regression analysis revealed that patients who used alcohol frequently during the last two weeks (OR=1.43; 95%CI: 1.15-1.77), those who were in contact with a positive case (OR=1.58; 95%CI: 1.33-1.88) and those who were obese (OR=1.82; 95%CI: 1.24-2.69) were significantly more likely to be a confirmed case after controlling for sociodemographic variables. Implementing a case investigation and contact-tracing component at community health centers can be of great value in the prevention and control of COVID-19 at the community level and could be used in future outbreaks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20health%20center" title="community health center">community health center</a>, <a href="https://publications.waset.org/abstracts/search?q=Puerto%20Rico" title=" Puerto Rico"> Puerto Rico</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=SARS-CoV-2" title=" SARS-CoV-2"> SARS-CoV-2</a> </p> <a href="https://publications.waset.org/abstracts/157619/sars-cov-2-transmission-risk-factors-among-patients-from-a-metropolitan-community-health-center-puerto-rico-july-2020-to-march-2022" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157619.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">115</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">307</span> Correlation between Fetal Umbilical Cord pH and the Day, the Time and the Team Hand over Times: An Analysis of 6929 Deliveries of the Ulm University Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabine%20Pau">Sabine Pau</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophia%20Volz"> Sophia Volz</a>, <a href="https://publications.waset.org/abstracts/search?q=Emanuel%20Bauer"> Emanuel Bauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Amelie%20De%20Gregorio"> Amelie De Gregorio</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Reister"> Frank Reister</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolfgang%20Janni"> Wolfgang Janni</a>, <a href="https://publications.waset.org/abstracts/search?q=Florian%20Ebner"> Florian Ebner </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: The umbilical cord pH is a well evaluated contributor for prediction of neonatal outcome.

All deliveries with a newborn cord pH under 7,20 were included in this analysis (6929 of 48974 deliveries (14,4%)). Further subgroups were formed according to the pH (< 7,05; 7,05 – 7,09; 7,10 – 7,14; 7,15 – 7,19). The data were then separated in day- and night time (8am-8pm/8pm-8am) for a first analysis. Finally, handover times were defined at 6 am – 6.30 am, 2 pm -2.30 pm, 10 pm- 10.30 pm (midwives) and for the doctors 8-8.30 am, 4 – 4.30 pm (Monday- Thursday); 2 pm -2.30 pm (Friday) and 9 am – 9.30 am (weekend). Routinely a shift consists of at least three doctors as well as three midwives. Results: During the last 20 years, 6929 neonates were born with an umbilical cord ph < 7,20 ( < 7,05 : 7,1%; 7,05 – 7,09 : 10,9%; 7,10 – 7,14 : 30,2%; 7,15 – 7,19:51,8%). There was no significant difference between either night/day delivery (p = 0.408), delivery on different weekdays (p = 0.253), delivery between Monday to Thursday, Friday and the weekend (p = 0.496 ) or delivery during the handover times of the doctors as well as the midwives (p = 0.221). Even the standard deviation showed no differences between the groups. Conclusion: Despite an increased workload over the last 20 years, the standard of care remains high even during the handover times and night shifts. This applies for midwives and doctors. As the neonatal outcome depends on various factors, further studies are necessary to take more factors influencing the fetal outcome into consideration. In order to maintain this high standard of care, an adaption of work-load and changing conditions is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delivery" title="delivery">delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=fetal%20umbilical%20cord%20pH" title=" fetal umbilical cord pH"> fetal umbilical cord pH</a>, <a href="https://publications.waset.org/abstracts/search?q=day%20time" title=" day time"> day time</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20over%20times" title=" hand over times"> hand over times</a> </p> <a href="https://publications.waset.org/abstracts/73592/correlation-between-fetal-umbilical-cord-ph-and-the-day-the-time-and-the-team-hand-over-times-an-analysis-of-6929-deliveries-of-the-ulm-university-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73592.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">316</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">306</span> Nutriscience Project: A Web-Based Intervention to Improve Nutritional Literacy among Families and Educators of Pre-School Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Barros">R.

Traditional nutrition education strategies for childhood obesity prevention have shown weak effect. The Nutriscience project aims to create and evaluate an innovative and multidisciplinary strategy for promoting effective and accessible nutritional information to children, their families, and educators. Nutriscience is a one-year prospective follow-up evaluation study including pre-school children (3-5 y), who attend national schools’ network (29). The project is structured around a web-based intervention, using an on-line interactive platform, and focus on increasing fruit and vegetable consumption, and reducing sugar and salt intake. The platform acts as a social network where educational materials, games, and nutritional challenges are proposed in a gamification approach that promotes family and community social ties. A nutrition Massive Online Open Course is developed for educators, and a national healthy culinary contest will be promoted on TV channel. A parental self-reported questionnaire assessing sociodemographic and nutritional literacy (knowledge, attitudes, skills) is administered (baseline and end of the intervention). We expect that results on nutritional literacy from the presented strategy intervention will give us important information about the best practices for health intervention with kindergarten families. This intervention program using a digital interactive platform could be an educational tool easily adapted and disseminated for childhood obesity prevention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=childhood%20obesity" title="childhood obesity">childhood obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20tool" title=" educational tool"> educational tool</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20literacy" title=" nutritional literacy"> nutritional literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=web-based%20intervention" title=" web-based intervention"> web-based intervention</a> </p> <a href="https://publications.waset.org/abstracts/55763/nutriscience-project-a-web-based-intervention-to-improve-nutritional-literacy-among-families-and-educators-of-pre-school-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55763.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">334</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">305</span> Depollution of the Pinheiros River in the City of São Paulo: Mapping the Dynamics of Conflicts and Coalitions between Actors in Two Recent Depollution Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adalberto%20Gregorio%20Back">Adalberto Gregorio Back</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Historically, the Pinheiros River, which crosses the urban area of the largest South American metropolis, the city of São Paulo, has been the subject of several interventions involving different interests and multiple demands, including the implementation of road axes and industrial occupation in the city, following its floodplains. the dilution of sewers; generation of electricity, with the reversal of its waters to the Billings Dam; and urban drainage. These processes, together with the exclusionary and peripheral urban sprawl with high population density in the peripheries, result in difficulties for the collection and treatment of household sewage, which flow into the tributaries and the Pinheiros River itself. In the last 20 years, two separate projects have been undertaken to clean up its waters. The first one between 2001-2011 was the flotation system, aimed at cleaning the river in its own gutter with equipment installed near the Bilings Dam; and, more recently, from 2019 to 2022, the proposal to connect about 74 thousand dwellings to the sewage collection and treatment system, as well as to install treatment plants in the tributaries of Pinheiros where the connection to the system is impracticable, given the irregular occupations. The purpose of this paper is to make a comparative analysis on the dynamics of conflicts, interests and opportunities of coalitions between the actors involved in the two referred projects of pollution of the Pinheiros River. For this, we use the analysis of documents produced by the state government; as well as documents related to the legal disputes that occurred in the first attempt of decontamination involving the sanitation company; the Billings Dam management company interested in power generation; the city hall and regular and irregular dwellings not linked to the sanitation system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=depollution%20of%20the%20Pinheiros%20River" title="depollution of the Pinheiros River">depollution of the Pinheiros River</a>, <a href="https://publications.waset.org/abstracts/search?q=interests%20groups" title=" interests groups"> interests groups</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%A3o%20Paulo" title=" São Paulo"> São Paulo</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20energy%20nexus" title=" water energy nexus"> water energy nexus</a> </p> <a href="https://publications.waset.org/abstracts/118887/depollution-of-the-pinheiros-river-in-the-city-of-sao-paulo-mapping-the-dynamics-of-conflicts-and-coalitions-between-actors-in-two-recent-depollution-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118887.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">106</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">304</span> Virtual Science Hub: An Open Source Platform to Enrich Science Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Barra">Enrique Barra</a>, <a href="https://publications.waset.org/abstracts/search?q=Aldo%20Gordillo"> Aldo Gordillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Quemada"> Juan Quemada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the Virtual Science Hub platform.

However, this measure can underestimate the true variance, specially for small samples. Traditionally, optimal design theory pays attention to this variance through its relationship with the model's information matrix. For this reason it seems convenient, at least in some cases, adapt the optimality criteria in order to get the best designs for the actual variance structure, otherwise the loss in efficiency of the designs obtained with the traditional approach may be very important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlated%20observations" title="correlated observations">correlated observations</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20matrix" title=" information matrix"> information matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=optimality%20criteria" title=" optimality criteria"> optimality criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=variance-covariance%20matrix" title=" variance-covariance matrix "> variance-covariance matrix </a> </p> <a href="https://publications.waset.org/abstracts/31104/biass-in-the-estimation-of-covariance-matrices-and-optimality-criteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31104.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">443</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">301</span> Mechanical Characterization of Banana by Inverse Analysis Method Combined with Indentation Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20F.%20P.%20Ram%C3%ADrez">Juan F.

This paper presents an analysis of network performance of last mile solution for the use of IPTV broadcasting with the application of streaming for telemedicine apps. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=telemedicine" title="telemedicine">telemedicine</a>, <a href="https://publications.waset.org/abstracts/search?q=IPTV" title=" IPTV"> IPTV</a>, <a href="https://publications.waset.org/abstracts/search?q=GPON" title=" GPON"> GPON</a>, <a href="https://publications.waset.org/abstracts/search?q=ADSL2%2B" title=" ADSL2+"> ADSL2+</a>, <a href="https://publications.waset.org/abstracts/search?q=coaxial" title=" coaxial"> coaxial</a>, <a href="https://publications.waset.org/abstracts/search?q=jumbogram" title=" jumbogram"> jumbogram</a> </p> <a href="https://publications.waset.org/abstracts/36100/transmission-performance-analysis-for-live-broadcasting-over-iptv-service-in-telemedicine-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36100.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">367</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">296</span> Intercultural Competencies as a Means to Rethink the Pedagogies of Diversity in Latin America</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Jose%20Cabarcas%20Ortega">Marcelo Jose Cabarcas Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Lissette%20Herrera"> Lissette Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Lemus%20Stave"> Juan Carlos Lemus Stave</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work makes a rather theoretical reflection on a pedagogical response against the coloniality of knowledge and power. The purpose here is to reflect on the challenges and opportunities it opens up in the educational field. No doubt, ours derived in a more abstract than concrete reflection. The quest, nevertheless, to stimulate the interest in a non-violent, non-contemptuous education able to balance, improves and if necessary, transforms the relationships that have made it a space of privilege and exclusion. We all know the school has found itself in need of rethinking diversity while developing awareness of its own role in reproducing inequality. Intercultural education may provide an answer to that hurry when fostering critical awareness and dialogue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decoloniality" title="decoloniality">decoloniality</a>, <a href="https://publications.waset.org/abstracts/search?q=coloniality%20of%20power" title=" coloniality of power"> coloniality of power</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=interculturality" title=" interculturality"> interculturality</a> </p> <a href="https://publications.waset.org/abstracts/136227/intercultural-competencies-as-a-means-to-rethink-the-pedagogies-of-diversity-in-latin-america" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136227.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">233</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">295</span> Math Rally Proposal for the Teaching-Learning of Algebra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liliana%20O.%20Mart%C3%ADnez">Liliana O.

The selected challenges and puzzles are intended to arouse students' interest in this area of mathematics, in addition to facilitating the teaching-learning process through challenges such as riddles, crossword puzzles, and board games, all in everyday situations that allow them to build themselves the learning. For this, it is proposed to carry out a "Math Rally: algebra" divided into four sections: mathematical reasoning, a hierarchy of operations, fractions, and algebraic equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algebra" title="algebra">algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=algebraic%20challenge" title=" algebraic challenge"> algebraic challenge</a>, <a href="https://publications.waset.org/abstracts/search?q=algebraic%20puzzle" title=" algebraic puzzle"> algebraic puzzle</a>, <a href="https://publications.waset.org/abstracts/search?q=math%20rally" title=" math rally"> math rally</a> </p> <a href="https://publications.waset.org/abstracts/156056/math-rally-proposal-for-the-teaching-learning-of-algebra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156056.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">168</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">294</span> Design, Development and Evaluation of a Portable Recording System to Capture Dynamic Presentations using the Teacher´s Tablet PC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Barra">Enrique Barra</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20Carril"> Abel Carril</a>, <a href="https://publications.waset.org/abstracts/search?q=Aldo%20Gordillo"> Aldo Gordillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Joaquin%20Salvachua"> Joaquin Salvachua</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Quemada"> Juan Quemada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computers and multimedia equipment have improved a lot in the last years. They have reduced costs and size while at the same time has increased their capabilities. These improvements allowed us to design and implement a portable recording system that also integrates the teacher´s tablet PC to capture what he/she writes on the slides and all that happens in it. This paper explains this system in detail and the validation of the recordings that we did after using it to record all the lectures of a course in our university called “Communications Software”. The results show that pupils used the recordings for different purposes and consider them useful for a variety of things, especially after missing a lecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recording%20system" title="recording system">recording system</a>, <a href="https://publications.waset.org/abstracts/search?q=capture%20dynamic%20presentations" title=" capture dynamic presentations"> capture dynamic presentations</a>, <a href="https://publications.waset.org/abstracts/search?q=lecture%20recording" title=" lecture recording"> lecture recording</a> </p> <a href="https://publications.waset.org/abstracts/2693/design-development-and-evaluation-of-a-portable-recording-system-to-capture-dynamic-presentations-using-the-teachers-tablet-pc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2693.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">366</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">293</span> Evaluation of Research in the Field of Energy Efficiency and MCA Methods Using Publications Databases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sep%C3%BAlveda">Juan Sepúlveda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy is a fundamental component in sustainability, the access and use of this resource is related with economic growth, social improvements, and environmental impacts. In this sense, energy efficiency has been studied as a factor that enhances the positive impacts of energy in communities; however, the implementation of efficiency requires strong policy and strategies that usually rely on individual measures focused in independent dimensions. In this paper, the problem of energy efficiency as a multi-objective problem is studied, using scientometric analysis to discover trends and patterns that allow to identify the main variables and study approximations related with a further development of models to integrate energy efficiency and MCA into policy making for small communities. <p class="card-text"><strong>Keywords:</strong> <a
