in the context of formal learning, the influence of affections, through subjective well-being, as well as the influence of personality, in the metacognition levels. There are few studies that analyze the influence of affection and personality on metacognition. The sample of this study consists of 300 Portuguese adolescents, male and female, aged between 15 and 17 years. The main variables of this study are affections, personality, ascertained through neuroticism and extraversion, and metacognition, namely the knowledge of cognition and the regulation of cognition. Initially, the sociodemographic questionnaire was constructed and administered to characterize the sample in its variables. To evaluate the affective experience in adolescents was administered PANAS-N, that is a measure of self-assessment of positive and negative affectivity in children and adolescents. To evaluate the personality, in its variables extroversion and neuroticism, the NEO-FFI was applied. The Metacognitive Awareness Inventory, MAI, was used to assess knowledge of cognition and regulation of cognition. The data analysis was performed using the statistical software IBM SPSS 22.0. After analyzing and discussing the results, a set of theoretical interdisciplinary reflection, between the sciences of education and psychology, is concretized, contributing to the reflection on psychoeducational intervention, opening the way for future studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affections" title="affections">affections</a>, <a href="https://publications.waset.org/abstracts/search?q=personality" title=" personality"> personality</a>, <a href="https://publications.waset.org/abstracts/search?q=metacognition" title=" metacognition"> metacognition</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoeducational%20intervention" title=" psychoeducational intervention"> psychoeducational intervention</a> </p> <a href="https://publications.waset.org/abstracts/69275/the-effects-of-affections-and-of-personality-on-metacognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69275.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">309</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">196</span> Dyeability of Silk Fabric with Dactylopius coccus Costa and Quercus infectoria Olivier </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burcu%20Yilmaz%20%C5%9Eahinba%C5%9Fkan">Burcu Yilmaz Şahinbaşkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Recep%20Karada%C4%9F"> Recep Karadağ</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Torgan"> Emine Torgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, many natural dyes are used for colouration of textile materials. The natural dyes are friendly to human health and environment. Cochineal (Dactylopius coccus Costa) can be used with other natural dye plants for colouration of silk and wool fabrics. Almost never research works on the dyeing of silk fabric with Dactylopius coccus Costa and Quercus infectoria Olivier together. In this study, dyeability of 100 % silk fabric with Dactylopius coccus Costa and Quercus infectoria Olivier was studied. Optimum dyeing parameters were determined by using different concentration of Dactylopius coccus Costa (10%), Quercus infectoria Olivier (0,1,5 and 10%) and mordant salt (0 and 3%). The dyed silk fabrics were examined for their colorimetric and fastness properties. The fabrics were dyed succesfully dark colours with 10 % Dactylopius coccus Costa, 10 % Quercus infectoria Olivier and presence of mordanting after dyeing process (3% mordant salt). The washing and light colour fastness of the dyed fabrics were investigated and adequate results were obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dactylopius%20coccus%20Costa" title="Dactylopius coccus Costa">Dactylopius coccus Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Quercus%20infectoria%20Olivier" title=" Quercus infectoria Olivier"> Quercus infectoria Olivier</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dye" title=" natural dye"> natural dye</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeing" title=" dyeing"> dyeing</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20fabric" title=" silk fabric"> silk fabric</a> </p> <a href="https://publications.waset.org/abstracts/25583/dyeability-of-silk-fabric-with-dactylopius-coccus-costa-and-quercus-infectoria-olivier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25583.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">597</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">195</span> The Green Propaganda: Paradoxes of Costa Rica as the Poster Child for Sustainable Tourism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Jose%20Ramos%20Villagra">Maria Jose Ramos Villagra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the boom of tourism in the late 80s and 90s, Costa Rica is considered as one of the leading countries for tourism. The size and geography of its territory, its low population density, and its image of being one of the most stable Latin American democracies make Costa Rica an attractive and safe target for foreign investors. Land ownership by foreign investors has increased as the natural resources in rural communities have been exhausted. When nature becomes an instrument to increase profit, it loses its communal value contributing to local communities losing their sovereignty and access to basic resources. The rural regions in proximity to the most tourist areas are often the most marginalized. The purpose of this research is to use the case of the rural community Sardinal and its struggle to protect its aquifer to investigate the economic and cultural consequences of the tourism boom in Costa Rican rural communities. The process of reclaiming the access to and the preservation of the aquifer enabled individuals to redefine their political views and their political power. The case of Sardinal broke the stereotypes about rural individuals and their ability to politically educate themselves and organize. Sardinal´s conflict brought to light the necessity of questioning the role of modern tourism as part of Costa Rica’s national identity, and as a tool for development <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Costa%20Rica" title="Costa Rica">Costa Rica</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20development" title=" rural development"> rural development</a>, <a href="https://publications.waset.org/abstracts/search?q=economy" title=" economy"> economy</a>, <a href="https://publications.waset.org/abstracts/search?q=ecotourism" title=" ecotourism"> ecotourism</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=Sardinal" title=" Sardinal"> Sardinal</a> </p> <a href="https://publications.waset.org/abstracts/38289/the-green-propaganda-paradoxes-of-costa-rica-as-the-poster-child-for-sustainable-tourism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38289.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">473</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">194</span> Digital Nomads: Current Context, Difficulties, and Opportunities for Costa Rica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Guti%C3%A9rrez%20Carranza">Cristina Gutiérrez Carranza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital nomadism is a trend and lifestyle which combines work and traveling. This tourism tendency is motivated by the desire to have a fixed source of financial income while becoming independent from a specific work location. This study contextualizes Costa Rica and its potential prospects to take advantage of this tourism market niche. It explores the dynamics of digital nomadism in the context of Costa Rica, analyzing the current scenario, challenges, and opportunities related to this global phenomenon. The research covers several areas, including the conceptualization of digital nomadism, its historical background, and contemporary manifestations. The investigation delves into the present state of digital nomadism, evaluating the extent of digitalization in Costa Rica, mobile phone coverage, and fixed internet access. As part of the strategies implemented, as the study develops, mapping the most common destinations of digital nomads is a key factor, bringing a sight on the aspects that make Costa Rica an attractive location for this emerging tourist group. Additionally, the paper draws insights from hosting entrepreneurs and digital nomads with work visas in Costa Rica, offering a comprehensive understanding of the experiences and perspectives from both sides. Hence, the study includes data from a sample of 20 digital nomads holding visas for Costa Rica, offering a detailed analysis of their professional activities, experiences and needs as remote workers in the country. As well it adds in perceptions from 10 entrepreneurs engaged in providing accommodation services to digital nomads contribute to a degree of understanding of the way they have faced this growing movement. This research provides significant insights on the dynamics of digital nomadism in Costa Rica by integrating data from specific sources. Policymakers, entrepreneurs, and other stakeholders are anticipated to gain valuable data from the findings regarding the opportunities and challenges of hosting and accommodating digital nomads, which will ultimately aid in the creation of plans to capitalize on this worldwide trend for the nation's socioeconomic development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20nomads" title="digital nomads">digital nomads</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20nomads%20visa" title=" digital nomads visa"> digital nomads visa</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20jobs" title=" remote jobs"> remote jobs</a> </p> <a href="https://publications.waset.org/abstracts/177942/digital-nomads-current-context-difficulties-and-opportunities-for-costa-rica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177942.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">193</span> Costa and Mccrae's Neo-Pi Factor and Early Adolescents School Social Adjustment in Cross River State Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Unoh%20Bassey">Peter Unoh Bassey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study examined the influence of Costa and McCrae’s Neo-PI Factor and early adolescent’s school social adjustment in Cross River State, Nigeria. The research adopted the causal-comparative design also known as the ex-post facto with about one thousand and eighteen (1,018) students who were randomly selected from one stream of JSS 1 classes in 19 schools out of seventy-three (73) in the study area. Data were collected using two instruments one is the NEO-PI scale, and students school social adjustment questionnaire. Three research questions and three research hypotheses were postulated and tested at 0.05 level of significance. The analysis of data was carried out using both the independent t-test statistics and the one-way analysis of variance (ANOVA). The analyzed result indicated that the five dimensions had a significant influence on students school social adjustment. A post hoc was equally carried out to show the relative significant difference among the study variables. In view of the above, it was recommended that teachers, parents and educational psychologists should be involved to enhance students the confidence to overcome their social adjustment problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Costa%20and%20McCrae%E2%80%99s%20NEO-PI%20Factor" title="Costa and McCrae’s NEO-PI Factor">Costa and McCrae’s NEO-PI Factor</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20adolescents" title=" early adolescents"> early adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=school" title=" school"> school</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20adjustment" title=" social adjustment"> social adjustment</a> </p> <a href="https://publications.waset.org/abstracts/105894/costa-and-mccraes-neo-pi-factor-and-early-adolescents-school-social-adjustment-in-cross-river-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105894.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">147</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">192</span> Applied Transdisciplinary Undergraduate Research in Costa Rica: Five Weeks Faculty-Led Study Abroad Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Shuger%20Fox">Sara Shuger Fox</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Reynaga"> Oscar Reynaga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This session explains the process and lessons learned as Central College (USA) faculty and staff developed undergraduate research opportunities within the model of a short-term faculty-led study abroad program in Costa Rica. The program in Costa Rica increases access to research opportunities across the disciplines and was developed by faculty from English, Biology, and Exercise Science. Session attendees will benefit from learning how faculty and staff navigated the program proposal process at a small liberal arts college and, in particular, how the program was built to be inclusive of departments with lower enrollment, like those currently seen in the humanities. Vital to this last point, presenters will explain how they negotiated issues of research supervision and disciplinary authority in such a way that the program is open to students from multiple disciplines without forcing the program budget to absorb costs for multiple faculty supervisors traveling and living in-country. Additionally, session attendees will learn how scouting laid the groundwork for mutually beneficial relationships between the program and the communities with which it collaborates. Presenters will explain how they built a coalition of students, faculty advisors, study abroad staff and local research hosts to support the development of research questions that are of value not just to the students, but to the community in which the research will take place. This program also incorporates principles of fair-trade learning by intentionally reporting research findings to local community members, as well as encouraging students to proactively share their research as a way to connect with local people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Costa%20Rica" title="Costa Rica">Costa Rica</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=transdisciplinary" title=" transdisciplinary"> transdisciplinary</a> </p> <a href="https://publications.waset.org/abstracts/75833/applied-transdisciplinary-undergraduate-research-in-costa-rica-five-weeks-faculty-led-study-abroad-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75833.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">1060</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">191</span> Bidirectional Encoder Representations from Transformers Sentiment Analysis Applied to Three Presidential Pre-Candidates in Costa Rica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F%C3%A9lix%20David%20Su%C3%A1rez%20Bonilla">Félix David Suárez Bonilla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A sentiment analysis service to detect polarity (positive, neural, and negative), based on transfer learning, was built using a Spanish version of BERT and applied to tweets written in Spanish.

There are currently only five recognized Blue Zones, two of which include Okinawa, Japan and the Nicoya Peninsula in Costa Rica. Individuals living in these areas tend to have positive outlooks on life, utilize daily movement, rely on strong social support groups, and eat little to no processed foods. The current research sought to further understand how centenarians living in Okinawa and in the Nicoya Peninsula utilize Blue Zone lifestyle elements in their daily living habits. To accomplish this, the author traveled to both Okinawa and the Nicoya Peninsula, Costa Rica, and interviewed several centenarians, paying particular attention to lifestyle choices and their effects on the aging process. Thematic analysis was used to analyze interview responses, and several themes emerged, such as the importance of family, friends, faith/spirituality, mindfulness, nutrition and daily movement as key foundations to aging in healthy and productive ways. Suggestions for ways to implement these habits globally was also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aging" title="aging">aging</a>, <a href="https://publications.waset.org/abstracts/search?q=blue%20zones" title=" blue zones"> blue zones</a>, <a href="https://publications.waset.org/abstracts/search?q=centenarians" title=" centenarians"> centenarians</a>, <a href="https://publications.waset.org/abstracts/search?q=nicoya%20peninsula" title=" nicoya peninsula"> nicoya peninsula</a>, <a href="https://publications.waset.org/abstracts/search?q=okinawa" title=" okinawa"> okinawa</a> </p> <a href="https://publications.waset.org/abstracts/169571/a-thematic-analysis-of-aging-in-blue-zone-regions-lessons-from-okinawa-and-the-nicoya-peninsula" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169571.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">257</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">187</span> Territorial Disputes behind the Declaration of Independence of Abkhazia and South Ossetia by Some Latin American States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Besik%20Goginava">Besik Goginava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several days later after the end of 2008 Russo-Georgian War, Venezuela and Nicaragua formally recognized the independence of Abkhazia and South Ossetia. In 2009-10 both countries established diplomatic relations with self-declared republics. It is a paradoxical fact that after neighboring Russia-Georgian conflict territories were internationally recognized by two Latin American states with ongoing territorial disputes. The Venezuela-Guyana territorial dispute which officially began in the early XIX century became conflict-ridden again in the late 1990s and 2000s. Venezuela has long claimed the land which comprises 40% of Guyana’s current territory. Territorial disputes of Nicaragua include dispute with Colombia over Caribbean Islands, with Costa Rica over the San Juan River and maritime dispute with Honduras. Based on historical and analytical research methods the purpose of this paper is to establish the relationship between the recognition of Abkhazia and South Ossetia by Venezuela and Nicaragua and Venezuela’s territorial dispute with Guyana, as well as Nicaragua’s with Colombia, Costa Rica and Honduras. The objective of the study is to investigate the factors that led Venezuela and Nicaragua to formally recognize Georgian conflict territories and how could their own territorial disputes affect on their decision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latin%20America" title="Latin America">Latin America</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgia" title=" Georgia"> Georgia</a>, <a href="https://publications.waset.org/abstracts/search?q=Venezuela" title=" Venezuela"> Venezuela</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicaragua" title=" Nicaragua"> Nicaragua</a>, <a href="https://publications.waset.org/abstracts/search?q=Abkhazia" title=" Abkhazia"> Abkhazia</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Ossetia" title=" South Ossetia"> South Ossetia</a> </p> <a href="https://publications.waset.org/abstracts/74253/territorial-disputes-behind-the-declaration-of-independence-of-abkhazia-and-south-ossetia-by-some-latin-american-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74253.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">244</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">186</span> Preliminary Design of an Aerodynamic Protection for the Scramjet Engine Inlet of the Brazilian Technological Demonstrator Scramjet 14-X S</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gustavo%20J.%20Costa">Gustavo J.

Hypersonic aerospace vehicles with air-breathing supersonic propulsion system face extremal environments for super/hypersonic flights in terms of thermal and aerodynamic loads. Thus, it is necessary to use aerodynamic protection at the scramjet engine inlet to face the thermal and aerodynamic loads without compromising the efficiency of scramjet engine, taking into account: i) inlet design (boundary layer, oblique shockwave and reflected oblique shockwave); ii) wall temperature of the cowl and of the compression ramp; iii) supersonic flow into the combustion chamber. The aerodynamic protection of the scramjet engine inlet will act to prevent the engine unstart and match the predictions made by theoretical-analytical, numerical analysis and experimental research, during the atmospheric flight of the Technological Demonstrator scramjet 14-X S. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=14-X" title="14-X">14-X</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersonic" title=" hypersonic"> hypersonic</a>, <a href="https://publications.waset.org/abstracts/search?q=scramjet" title=" scramjet"> scramjet</a>, <a href="https://publications.waset.org/abstracts/search?q=supersonic%20combustion" title=" supersonic combustion"> supersonic combustion</a> </p> <a href="https://publications.waset.org/abstracts/59517/preliminary-design-of-an-aerodynamic-protection-for-the-scramjet-engine-inlet-of-the-brazilian-technological-demonstrator-scramjet-14-x-s" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59517.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">425</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">185</span> Tectonics in Sustainable Contemporary Architecture: An Approach to the Intersection between Design and Construction in the Work of Norman Foster</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mafalda%20Fabiene%20Ferreira%20Pantoja">Mafalda Fabiene Ferreira Pantoja</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Da%20Costa%20Pantoja"> Joao Da Costa Pantoja</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Humberto%20Costa%20De%20Fernandes%20Povoas"> Rui Humberto Costa De Fernandes Povoas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper seeks to present a theoretical and practical reflection about examples of contemporary architecture in the world context where concerns about the planet become prominent and increasingly necessary. Firstly, a brief introduction will be made on the conceptual principles of tectonics in architecture in order to apply such concepts in a perspective of analysis of the intersection between design and construction in contemporary examples of Norman Foster’s architecture, once his work has demonstrated attitudes of composition that concerns about the place, technology, materials, and building life. Foster's compositions are usually focused on the role of technology in the process of architectural design, making his works a mixture of place, program, construction, and formal structures. The main purpose of the present paper is the reflection on the tools of theoretical and practical analysis about tectonics, optimizing the resources that allow cultural anchoring and creation of identity. Also establishing relation between resources, building life cycle and employment of correct materials, in order to find out how the tectonic concept can elevate the status of contemporary architecture, making it qualitative in a more sustainable context and adapted to current needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contemporary%20architecture" title="contemporary architecture">contemporary architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=norman%20foster" title=" norman foster"> norman foster</a>, <a href="https://publications.waset.org/abstracts/search?q=tectonic" title=" tectonic"> tectonic</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20architecture" title=" sustainable architecture"> sustainable architecture</a> </p> <a href="https://publications.waset.org/abstracts/111569/tectonics-in-sustainable-contemporary-architecture-an-approach-to-the-intersection-between-design-and-construction-in-the-work-of-norman-foster" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111569.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">184</span> Women Trainees' Perception on Non-Formal Educational Workshops in Improving Their Socio-Economic Status in Algeria and Costa Rica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahia%20Braktia">Bahia Braktia</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Anna%20Marcela%20Montenegro"> S.

In a developing framework, it is regarded as a practical approach for social inclusion and poverty reduction. They are also perceived as a way to serve adults who did not have the chance to education in their early ages by providing them knowledge, skills and values. Non-formal adult education and trainings are critical means in a society to break poverty and unemployment, and to decrease the social inequality. This paper investigates the perception of women trainees about a series of workshops in natural beauty products, held in Algeria and Costa Rica and organized by a non-profit educational organization, to improve their socio-economic status. This research seeks to explore ways of empowering women by assessing their needs and providing them with skills to start their own business. A questionnaire is administered before the workshops and focus groups are held at the end. A qualitative research method is employed to analyze the data. Preliminary results show that the trainees aspire to create their businesses with the objectives of poverty reduction and social inclusion. The findings also reveal the need for small business funding programs and entrepreneurial training programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult%20education" title="adult education">adult education</a>, <a href="https://publications.waset.org/abstracts/search?q=non-formal%20education" title=" non-formal education"> non-formal education</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-economic%20status" title=" socio-economic status"> socio-economic status</a>, <a href="https://publications.waset.org/abstracts/search?q=women%20empowerment" title=" women empowerment"> women empowerment</a> </p> <a href="https://publications.waset.org/abstracts/95214/women-trainees-perception-on-non-formal-educational-workshops-in-improving-their-socio-economic-status-in-algeria-and-costa-rica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95214.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">208</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">183</span> Machine Learning for Classifying Risks of Death and Length of Stay of Patients in Intensive Unit Care Beds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Itamir%20de%20Morais%20Barroca%20Filho">Itamir de Morais Barroca Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Cephas%20A.%20S.%20Barreto"> Cephas A.

These ICTs are also known as e-health and comprise technologies such as electronic record systems, telemedicine systems, and personalized devices for diagnosis. The focus of e-health is to improve the quality of health information, strengthen national health systems, and ensure accessible, high-quality health care for all. All the data gathered by these technologies make it possible to help clinical staff with automated decisions using machine learning. In this context, we collected patient data, such as heart rate, oxygen saturation (SpO2), blood pressure, respiration, and others. With this data, we were able to develop machine learning models for patients’ risk of death and estimate the length of stay in ICU beds. Thus, this paper presents the methodology for applying machine learning techniques to develop these models. As a result, although we implemented these models on an IoT healthcare platform, helping clinical staff in healthcare in an ICU, it is essential to create a robust clinical validation process and monitoring of the proposed models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ICT" title="ICT">ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=e-health" title=" e-health"> e-health</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ICU" title=" ICU"> ICU</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a> </p> <a href="https://publications.waset.org/abstracts/163535/machine-learning-for-classifying-risks-of-death-and-length-of-stay-of-patients-in-intensive-unit-care-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163535.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">110</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">182</span> Coastalization and Urban Sprawl in the Mediterranean: Using High-Resolution Multi-Temporal Data to Identify Typologies of Spatial Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apostolos%20Lagarias">Apostolos Lagarias</a>, <a href="https://publications.waset.org/abstracts/search?q=Anastasia%20Stratigea"> Anastasia Stratigea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coastal urbanization is heavily affecting the Mediterranean, taking the form of linear urban sprawl along the coastal zone. This process is posing extreme pressure on ecosystems, leading to an unsustainable model of growth. The aim of this research is to analyze coastal urbanization patterns in the Mediterranean using High-resolution multi-temporal data provided by the Global Human Settlement Layer (GHSL) database. Methodology involves the estimation of a set of spatial metrics characterizing the density, aggregation/clustering and dispersion of built-up areas. As case study areas, the Spanish Coast and the Adriatic Italian Coast are examined. Coastalization profiles are examined and selected sub-areas massively affected by tourism development and suburbanization trends (Costa Blanca/Murcia, Costa del Sol, Puglia, Emilia-Romagna Coast) are analyzed and compared. Results show that there are considerable differences between the Spanish and the Italian typologies of spatial development, related to the land use structure and planning policies applied in each case. Monitoring and analyzing spatial patterns could inform integrated Mediterranean strategies for coastal areas and redirect spatial/environmental policies towards a more sustainable model of growth <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastalization" title="coastalization">coastalization</a>, <a href="https://publications.waset.org/abstracts/search?q=Mediterranean" title=" Mediterranean"> Mediterranean</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-temporal" title=" multi-temporal"> multi-temporal</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20sprawl" title=" urban sprawl"> urban sprawl</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20metrics" title=" spatial metrics"> spatial metrics</a> </p> <a href="https://publications.waset.org/abstracts/134375/coastalization-and-urban-sprawl-in-the-mediterranean-using-high-resolution-multi-temporal-data-to-identify-typologies-of-spatial-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134375.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">138</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">181</span> Soils Properties of Alfisols in the Nicoya Peninsula, Guanacaste, Costa Rica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Listo">Elena Listo</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Marchamalo"> Miguel Marchamalo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research studies the soil properties located in the watershed of Jabillo River in the Guanacaste province, Costa Rica. The soils are classified as Alfisols (T. Haplustalfs), in the flatter parts with grazing as Fluventic Haplustalfs or as a consequence of bad drainage as F. Epiaqualfs. The objective of this project is to define the status of the soil, to use remote sensing as a tool for analyzing the evolution of land use and determining the water balance of the watershed in order to improve the efficiency of the water collecting systems. Soil samples were analyzed from trial pits taken from secondary forests, degraded pastures, mature teak plantation, and regrowth -Tectona grandis L. F.- species developed favorably in the area. Furthermore, to complete the study, infiltration measurements were taken with an artificial rainfall simulator, as well as studies of soil compaction with a penetrometer, in points strategically selected from the different land uses. Regarding remote sensing, nearly 40 data samples were collected per plot of land. The source of radiation is reflected sunlight from the beam and the underside of leaves, bare soil, streams, roads and logs, and soil samples. Infiltration reached high levels. The majority of data came from the secondary forest and mature planting due to a high proportion of organic matter, relatively low bulk density, and high hydraulic conductivity. Teak regrowth had a low rate of infiltration because the studies made regarding the soil compaction showed a partial compaction over 50 cm. The secondary forest presented a compaction layer from 15 cm to 30 cm deep, and the degraded pasture, as a result of grazing, in the first 15 cm. In this area, the alfisols soils have high content of iron oxides, a fact that causes a higher reflectivity close to the infrared region of the electromagnetic spectrum (around 700mm), as a result of clay texture. Specifically in the teak plantation where the reflectivity reaches values of 90 %, this is due to the high content of clay in relation to others. In conclusion, the protective function of secondary forests is reaffirmed with regards to erosion and high rate of infiltration. In humid climates and permeable soils, the decrease of runoff is less, however, the percolation increases. The remote sensing indicates that being clay soils, they retain moisture in a better way and it means a low reflectivity despite being fine texture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alfisols" title="alfisols">alfisols</a>, <a href="https://publications.waset.org/abstracts/search?q=Costa%20Rica" title=" Costa Rica"> Costa Rica</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration" title=" infiltration"> infiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a> </p> <a href="https://publications.waset.org/abstracts/33702/soils-properties-of-alfisols-in-the-nicoya-peninsula-guanacaste-costa-rica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33702.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">694</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">180</span> Erectile Function and Heart Rate Variability in Men under 40 Years Old</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rui%20Miguel%20Costa">Rui Miguel Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Pestana"> Jose Pestana</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Costa"> David Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Paula%20Mangia"> Paula Mangia</a>, <a href="https://publications.waset.org/abstracts/search?q=Catarina%20Correia"> Catarina Correia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mafalda%20Pinto%20Coelho"> Mafalda Pinto Coelho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is lack of studies examining the relation of different heart rate variability (HRV) parameters with the risk of erectile dysfunction (ED) in younger men. Thus, the present study aimed at examining, in a nonclinical sample of men aged 19-39 years old (mean age = 23.98 years, SD = 4.90), the relations of risk of ED with the standard deviation of the heart rate (SD of HR), high and low frequency power of HRV, and low-to-high frequency HRV ratio. Eighty-three heterosexual Portuguese men completed the 5-item version of the International Index of Erectile Function (IIEF-5) and HRV parameters were calculated from a 5-minute resting period. Risk of ED was determined by IIEF-5 scores of 21 or less. Fifteen men (18.1%) reported symptoms of ED (14 with mild and one with mild to moderate symptoms). Univariate analyses of variance revealed that risk of ED was related to lesser SD of HR and lesser low-frequency power, the two HRV parameters that express a coupling of higher vagal and sympathetic tone. Risk of ED was unrelated to high-frequency power and low-to-high frequency HRV ratio. Further, in a logistic regression, the risk of ED was independently predicted by older age and lower SD of HR, but not by low-frequency power, having a regular sexual partner, and cohabiting. The results provide preliminary evidence that, in younger men, a coupling of higher vagal and sympathetic tone, as indexed by the SD of HR, is important for erections. Greater resting SD of HR might reflect better vascular and interpersonal function via vagal tone coupled with greater motor mobilization to pursue sexual intercourse via sympathetic tone. Many interventions can elevate HRV; future research is warranted on how they can be tailored to treat ED in younger men. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erectile%20dysfunction" title="erectile dysfunction">erectile dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate%20variability" title=" heart rate variability"> heart rate variability</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20deviation%20of%20the%20heart%20rate" title=" standard deviation of the heart rate"> standard deviation of the heart rate</a>, <a href="https://publications.waset.org/abstracts/search?q=younger%20men" title=" younger men"> younger men</a> </p> <a href="https://publications.waset.org/abstracts/92756/erectile-function-and-heart-rate-variability-in-men-under-40-years-old" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92756.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">276</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">179</span> Exploring Gender-Based Violence in Indigenous Communities in Argentina and Costa Rica: A Review of the Current Literature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jocelyn%20Jones">Jocelyn Jones</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this literature review is to provide an assessment of the current literature concerning gender-based violence (GBV) within indigenous communities in Argentina and Costa Rica, and various public intervention strategies that have been implemented to counter the increasing rates of violence within these populations. The review will address some of the unique challenges and contextual factors influencing the prevalence and response to such violence, including the enduring impact of colonialism on familial structures, community dynamics, and the perpetuation of violence. Drawing on indigenous feminist perspectives, the paper critically assesses the intersectionality of gender, ethnicity, and socio-economic status in shaping the experiences of indigenous women, men, and gender-diverse individuals. In comparing the two nations, the literature review identifies commonalities and divergences in policy frameworks, legal responses, and grassroots initiatives aimed at addressing GBV. Regarding the assessment of the efficacy of existing interventions, the paper will consider the role of cultural revitalization, community engagement, and collaborative efforts between indigenous communities and external agencies in the development of future policies. Moreover, the review will highlight the importance of decolonizing methodologies in research and intervention strategies, and the need to emphasise culturally sensitive approaches that respect and integrate indigenous worldviews and traditional knowledge systems. Additionally, the paper will explore the potential impact of colonial legacies, resource extraction, and land dispossession on exacerbating vulnerabilities to GBV within indigenous communities. The aim of this paper is to contribute to a more in-depth understanding of GBV in indigenous contexts in order to promote cross-cultural learning and inform future research. Ultimately, this review will demonstrate the necessity of adopting a holistic and context-specific approach to address gender-based violence in indigenous communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20based%20violence" title="gender based violence">gender based violence</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous" title=" indigenous"> indigenous</a>, <a href="https://publications.waset.org/abstracts/search?q=colonialism" title=" colonialism"> colonialism</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a> </p> <a href="https://publications.waset.org/abstracts/183009/exploring-gender-based-violence-in-indigenous-communities-in-argentina-and-costa-rica-a-review-of-the-current-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183009.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">77</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">178</span> Rapid Algorithm for GPS Signal Acquisition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabricio%20Costa%20Silva">Fabricio Costa Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Xavier%20de%20Souza"> Samuel Xavier de Souza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Global Positioning System (GPS) receiver is responsible to determine position, velocity and timing information by using satellite information.

The paper analyzes the continuous negotiation between the need for environmental protection in the face of pineapple monoculture and the socioeconomic dependencies of the community on the company. Drawing on eight years of ethnographic work in Volcan de Buenos Aires and relying on intergenerational interviews that document oral histories, this article provides a socio-historical account of the economic and environmental impact of the presence of PINDECO in the southern zone of the country. The paper draws on interviews and in-depth participant observation, conducted by the author in intermittent periods over eight years. The research sheds light on the tensions between the village and PINDECO, as simultaneous acceptance of and opposition to the company persist by different stakeholders in the region. In doing so, this paper examines the strikingly powerful affinity toward the company and the community's regard for PINDECO as the town patriarch despite social and environmental injustices. In demonstrating these tensions, the author problematizes the practice of conducting foreign environmental research in developing countries, and more importantly, proposing changes to environmental conservation and socioeconomic structures without understanding community reliance on the presence of corporations such as PINDECO and the threats that changes to existing structures could pose to community members' livelihoods. In complicating these common western academic practices, the author takes an anti-colonial approach to environmental research, refusing the assumption that the affinity toward the company by the community of Volcan is rooted in ignorance, lack of education, or lack of interest in environmental conservation. The author instead highlights local knowledge and agency, demonstrating the many ways in which the community itself is producing knowledge and taking action. Through this paper, common assumptions regarding the agency of such communities are contested, and the grassroots environmental initiatives of Volcan, Costa Rica are brought to life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20conservation" title="environmental conservation">environmental conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=grassroots%20movements" title=" grassroots movements"> grassroots movements</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20knowledge" title=" local knowledge"> local knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20multinational" title=" agricultural multinational"> agricultural multinational</a> </p> <a href="https://publications.waset.org/abstracts/118463/pineapple-patriarch-local-agency-in-sustainability-initiatives-despite-community-reliance-on-pineapple-monoculture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118463.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">134</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">172</span> Household Earthquake Absorptive Capacity Impact on Food Security: A Case Study in Rural Costa Rica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Rodr%C3%ADguez%20Amaya">Laura Rodríguez Amaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of natural disasters on food security can be devastating, especially in rural settings where livelihoods are closely tied to their productive assets. In hazards studies, absorptive capacity is seen as a threshold that impacts the degree of people’s recovery after a natural disaster. Increasing our understanding of households’ capacity to absorb natural disaster shocks can provide the international community with viable measurements for assessing at-risk communities’ resilience to food insecurities. The purpose of this study is to identify the most important factors in determining a household’s capacity to absorb the impact of a natural disaster. This is an empirical study conducted in six communities in Costa Rica affected by earthquakes. The Earthquake Impact Index was developed for the selection of the communities in this study. The households coded as total loss in the selected communities constituted the sampling frame from which the sample population was drawn. Because of the study area geographically dispersion over a large surface, the stratified clustered sampling hybrid technique was selected. Of the 302 households identified as total loss in the six communities, a total of 126 households were surveyed, constituting 42 percent of the sampling frame. A list of indicators compiled based on theoretical and exploratory grounds for the absorptive capacity construct served to guide the survey development. These indicators were included in the following variables: (1) use of informal safety nets, (2) Coping Strategy, (3) Physical Connectivity, and (4) Infrastructure Damage. A multivariate data analysis was conducted using Statistical Package for Social Sciences (SPSS). The results show that informal safety nets such as family and friends assistance exerted the greatest influence on the ability of households to absorb the impact of earthquakes. In conclusion, communities that experienced the highest environmental impact and human loss got disconnected from the social networks needed to absorb the shock’s impact. This resulted in higher levels of household food insecurity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorptive%20capacity" title="absorptive capacity">absorptive capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a>, <a href="https://publications.waset.org/abstracts/search?q=rural" title=" rural"> rural</a> </p> <a href="https://publications.waset.org/abstracts/74707/household-earthquake-absorptive-capacity-impact-on-food-security-a-case-study-in-rural-costa-rica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74707.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">253</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">171</span> Risk of Occupational Exposure to Cytotoxic Drugs: The Role of Handling Procedures of Hospital Workers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Silva">J.

Teachers play a crucial role in educational attainment because they stand in the interface of the transmission of knowledge, values, and skills in the learning process through the instructional strategies they employ in the classroom. The level of achievement of students in school depends on the degree of effectiveness of instructional strategies used by the teacher. Thus, this study was conceptualized and conducted to examine the instructional strategies preferred and used by the Science and Mathematics teachers and the impact of those strategies in their teaching performance and students’ academic achievement in Science and Mathematics. The participants of the study comprised a total enumeration of 61 teachers who were chosen through total enumeration and 610 students who were selected using two-stage random sampling technique. The descriptive correlation design was used in this study with a self-made questionnaire as the main tool in the data gathering procedure. Relationship among variables was tested and analyzed using Spearman Rank Correlation Coefficient and Wilcoxon Signed Rank statistics. The teacher participants under study mainly belonged to the age group of ‘young’ (35 years and below) and most were females having ‘very much experienced’ (16 years and above) in teaching. Teaching performance was found to be ‘very satisfactory’ while academic achievement in Science and Mathematics was found to be ‘satisfactory’. Demographic profile and teaching performance of teacher participants were found to be ‘not significant’ to their instructional strategy preferences. Results implied that age, sex, level of education and length of service of the teachers does not affect their preference on a particular instructional strategy. However, the teacher participants’ extent of use of the different instructional strategies was found to be ‘significant’ to their teaching performance. The instructional strategies being used by the teachers were found to have a direct effect on their teaching performance. Academic achievement of student participants was found to be ‘significant’ to the teacher participants’ instructional strategy preferences. The preference of the teachers on instructional strategies had a significant effect on the students’ academic performance. On the other hand, teacher participants’ extent of use of instructional strategies was showed to be ‘not significant’ to the academic achievement of students in Science and Mathematics. The instructional strategy being used by the teachers did not affect the level of performance of students in Science and Mathematics. The results of the study revealed that there was a significant difference between the teacher participants’ preference of instructional strategy and the student participants’ instructional strategy preference as well as between teacher participants’ extent of use and student participants’ perceived level of use of the different instructional strategies. Findings found a discrepancy between the teaching strategy preferences of students and strategies implemented by teachers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title="academic achievement">academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=extent%20of%20use" title=" extent of use"> extent of use</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20strategy" title=" instructional strategy"> instructional strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=preferences" title=" preferences"> preferences</a> </p> <a href="https://publications.waset.org/abstracts/38059/science-and-mathematics-instructional-strategies-teaching-performance-and-academic-achievement-in-selected-secondary-schools-in-upland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38059.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">313</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">169</span> Microclimate Variations in Rio de Janeiro Related to Massive Public Transportation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20E.%20O.%20Jardim">Marco E.

This work presents an infrastructure built to better understand microclimate variations related to massive urban transportation in some specific areas of the city. The use of sensor nodes with small analytics capacity provides environmental information to population or public services. The analyses of data collected from a few small sensors positioned near some heavy traffic streets show the harmful impact due to poor bus route plan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transportation" title=" public transportation"> public transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health%20system" title=" public health system"> public health system</a> </p> <a href="https://publications.waset.org/abstracts/108752/microclimate-variations-in-rio-de-janeiro-related-to-massive-public-transportation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108752.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">253</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">168</span> Water Balance in the Forest Basins Essential for the Water Supply in Central America</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Listo%20Ubeda">Elena Listo Ubeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Marchamalo%20Sacristan"> Miguel Marchamalo Sacristan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The demand for water doubles every twenty years, at a rate which is twice as fast as the world´s population growth. Despite it´s great importance, water is one of the most degraded natural resources in the world, mainly because of the reduction of natural vegetation coverage, population growth, contamination and changes in the soil use which reduces its capacity to collect water. This situation is especially serious in Central America, as reflected in the Human Development reports. The objective of this project is to assist in the improvement of water production and quality in Central America. In order to do these two watersheds in Costa Rica were selected as experiments: that of the Virilla-Durazno River, located in the extreme north east of the central valley which has an Atlantic influence; and that of the Jabillo River, which flows directly into the Pacific. The Virilla river watershed is located over andisols, and that of the Jabillo River is over alfisols, and both are of great importance for water supply to the Greater Metropolitan Area and the future tourist resorts respectively, as well as for the production of agriculture, livestock and hydroelectricity. The hydrological reaction in different soil-cover complexes, varying from the secondary forest to natural vegetation and degraded pasture, was analyzed according to the evaluation of the properties of the soil, infiltration, soil compaction, as well as the effects of the soil cover complex on erosion, calculated by the C factor of the Revised Universal Soil Loss Equation (RUSLE). A water balance was defined for each watershed, in which the volume of water that enters and leaves were estimated, as well as the evapotranspiration, runoff, and infiltration. Two future scenarios, representing the implementation of reforestation and deforestation plans, were proposed, and were analyzed for the effects of the soil cover complex on the water balance in each case. The results obtained show an increase of the ground water recharge in the humid forest areas, and an extension of the study of the dry areas is proposed since the ground water recharge here is diminishing. These results are of great significance for the planning, design of Payment Schemes for Environmental Services and the improvement of the existing water supply systems. In Central America spatial planning is a priority, as are the watersheds, in order to assess the water resource socially and economically, and securing its availability for the future. <p
