Thus, liquid-liquid equilibria of the ternary solutions (nicotine+water+NaCl) and (nicotine+water+ECOENG212®) were determined at ambient pressure, 0.1 MPa, at three temperatures. The related phase diagrams were constructed in two manners: by adding the determined cloud-points and by the chemical analysis of phases in equilibrium (tie-line data). The latter were used to calculate two important separation parameters - partition coefficients of nicotine and separation factors. The impacts of the initial compositions of the mother solutions and of temperature on the liquid-liquid phase separation and partition coefficients were analyzed and discussed. The results obtained clearly showed that both investigated salts are good salting-out media for the efficient and sustainable separation of nicotine from its solutions with water. However, when compared, sodium chloride exhibited much better separation performance than the ionic liquid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nicotine" title="nicotine">nicotine</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20separation" title=" liquid-liquid separation"> liquid-liquid separation</a>, <a href="https://publications.waset.org/abstracts/search?q=inorganic%20salt" title=" inorganic salt"> inorganic salt</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquid" title=" ionic liquid"> ionic liquid</a> </p> <a href="https://publications.waset.org/abstracts/58412/sustainable-separation-of-nicotine-from-its-aqueous-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58412.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">311</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">99</span> 3D Dentofacial Surgery Full Planning Procedures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oliveira%20M.">Oliveira M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Gon%C3%A7alves%20L."> Gonçalves L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20I."> Francisco I.</a>, <a href="https://publications.waset.org/abstracts/search?q=Caramelo%20F."> Caramelo F.</a>, <a href="https://publications.waset.org/abstracts/search?q=Vale%20F."> Vale F.</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanz%20D."> Sanz D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Domingues%20M."> Domingues M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Lopes%20M."> Lopes M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Moreia%20D."> Moreia D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Lopes%20T."> Lopes T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Santos%20T."> Santos T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cardoso%20H."> Cardoso H.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ARTHUR project consists of a platform that allows the virtual performance of maxillofacial surgeries, offering, in a photorealistic concept, the possibility for the patient to have an idea of the surgical changes before they are performed on their face. For this, the system brings together several image formats, dicoms and objs that, after loading, will generate the bone volume, soft tissues and hard tissues. The system also incorporates the patient's stereophotogrammetry, in addition to their data and clinical history. After loading and inserting data, the clinician can virtually perform the surgical operation and present the final result to the patient, generating a new facial surface that contemplates the changes made in the bone and tissues of the maxillary area. This tool acts in different situations that require facial reconstruction, however this project focuses specifically on two types of use cases: bone congenital disfigurement and acquired disfiguration such as oral cancer with bone attainment. Being developed a cloud based solution, with mobile support, the tool aims to reduce the decision time window of patient. Because the current simulations are not realistic or, if realistic, need time due to the need of building plaster models, patient rates on decision, rely on a long time window (1,2 months), because they don’t identify themselves with the presented surgical outcome. On the other hand, this planning was performed time based on average estimated values of the position of the maxilla and mandible. The team was based on averages of the facial measurements of the population, without specifying racial variability, so the proposed solution was not adjusted to the real individual physiognomic needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20computing" title="3D computing">3D computing</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20registry" title=" image registry"> image registry</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20reconstruction" title=" image reconstruction"> image reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/144601/3d-dentofacial-surgery-full-planning-procedures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144601.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">206</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">98</span> Using Textual Pre-Processing and Text Mining to Create Semantic Links</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Avila">Ricardo Avila</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Lopes"> Gabriel Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Vania%20Vidal"> Vania Vidal</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Macedo"> Jose Macedo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article offers a approach to the automatic discovery of semantic concepts and links in the domain of Oil Exploration and Production (E&P).

Alkaline leaching of lithium concentrates allows the establishment of a production diagram avoiding most of the environmental drawbacks that are associated with the usage of acid reagents. The tested processes involve a pretreatment by digestion at high temperatures with additives, followed by leaching at hot atmospheric pressure. The solutions obtained must be compatible with solutions from the leaching of spodumene concentrates, allowing the development of a common treatment diagram, an important accomplishment for the feasible exploitation of Portuguese resources.

Traditional analytical techniques tend to require complex steps and expensive equipment however DNA biosensors have the advantage of getting simple, fast and economic. Additionally, the combination of DNA biosensors with nanomaterials offers the opportunity to improve the selectivity, sensitivity and the overall performance of the devices. DNA biosensors are based on oligonucleotides as sensing elements. These oligonucleotides are highly specific to complementary DNA sequences resulting in the hybridization of the strands. DNA biosensors are not only an advantage in the clinical field but also applicable in numerous research areas such as food analysis or environmental control. Zebra Mussels (ZM), Dreissena polymorpha are invasive species responsible for enormous negative impacts on the environment and ecosystems. Generally, the detection of ZM is made when the observation of adult or macroscopic larvae's is made however at this stage is too late to avoid the harmful effects. Therefore, there is a need to develop an analytical tool for the early detection of ZM. Here, we present a portable plasmonic biosensor for the detection of environmental DNA (eDNA) released to the environment from this invasive species. The plasmonic DNA biosensor combines gold nanoparticles, as transducer elements, due to their great optical properties and high sensitivity. The detection strategy is based on the immobilization of a short base pair DNA sequence on the nanoparticles surface followed by specific hybridization in the presence of a complementary target DNA. The hybridization events are tracked by the optical response provided by the nanospheres and their surrounding environment. The identification of the DNA sequences (synthetic target and probes) to detect Zebra mussel were designed by using Geneious software in order to maximize the specificity. Moreover, to increase the optical response enzyme amplification of DNA might be used. The gold nanospheres were synthesized and characterized by UV-visible spectrophotometry and transmission electron microscopy (TEM). The obtained nanospheres present the maximum localized surface plasmon resonance (LSPR) peak position are found to be around 519 nm and a diameter of 17nm. The DNA probes modified with a sulfur group at one end of the sequence were then loaded on the gold nanospheres at different ionic strengths and DNA probe concentrations. The optimal DNA probe loading will be selected based on the stability of the optical signal followed by the hybridization study. Hybridization process leads to either nanoparticle dispersion or aggregation based on the presence or absence of the target DNA. Finally, this detection system will be integrated into an optical sensing platform. Considering that the developed device will be used in the field, it should fulfill the inexpensive and portability requirements. The sensing devices based on specific DNA detection holds great potential and can be exploited for sensing applications in-loco. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZM%20DNA" title="ZM DNA">ZM DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20probes" title=" DNA probes"> DNA probes</a>, <a href="https://publications.waset.org/abstracts/search?q=nicking%20enzyme" title=" nicking enzyme"> nicking enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoparticles" title=" gold nanoparticles"> gold nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/91433/plasmonic-biosensor-for-early-detection-of-environmental-dna-edna-combined-with-enzyme-amplification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91433.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">245</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">93</span> Syntactic, Semantic, and Pragmatic Rationalization of Modal Auxiliary Verbs in Akan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joana%20Portia%20Sakyi">Joana Portia Sakyi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The uniqueness of auxiliary verbs and their contribution to grammar as constituents, which act as preverbs to supply additional grammatical or functional meanings to clauses, are well established. Functionally, they relate clauses to tense, aspect, mood, voice, emphasis, and modality, along with the main verbs conveying the appropriate lexical content. There has been an issue in Akan grammar vis-à-vis the status of auxiliary verbs, in terms of whether Akan has auxiliaries or not and even which forms are to be regarded as auxiliaries. We investigate the syntactic, semantic, and pragmatic components of expressions and claim that Akan has auxiliary verbs that contribute the functional or grammatical meaning of modality, tense/aspect, etc., to clauses they occur in. Essentially, we use a self-created corpus data to consider the affix bέ- ‘may’, ‘must’, ‘should’; the form tùmí ‘can’, ‘be able to’; mà ‘to let’, ‘to allow’, ‘to permit’, ‘to make’, or ‘to cause’ someone to do something; the multi-word forms ὲsὲ sέ ‘must’, ‘should’ or ‘have to’ and ètwà sέ ‘must’, ‘should’ or ‘have to’, and assert that they are legitimate modal auxiliaries conveying epistemic, deontic, and dynamic modalities, as well as other meanings in the language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akan" title="Akan">Akan</a>, <a href="https://publications.waset.org/abstracts/search?q=modality" title=" modality"> modality</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20auxiliaries" title=" modal auxiliaries"> modal auxiliaries</a>, <a href="https://publications.waset.org/abstracts/search?q=semantics" title=" semantics"> semantics</a> </p> <a href="https://publications.waset.org/abstracts/172032/syntactic-semantic-and-pragmatic-rationalization-of-modal-auxiliary-verbs-in-akan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172032.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">92</span> Discovering Semantic Links Between Synonyms, Hyponyms and Hypernyms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Avila">Ricardo Avila</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Lopes"> Gabriel Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Vania%20Vidal"> Vania Vidal</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Macedo"> Jose Macedo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This proposal aims for semantic enrichment between glossaries using the Simple Knowledge Organization System (SKOS) vocabulary to discover synonyms, hyponyms and hyperonyms semiautomatically, in Brazilian Portuguese, generating new semantic relationships based on WordNet. To evaluate the quality of this proposed model, experiments were performed by the use of two sets containing new relations, being one generated automatically and the other manually mapped by the domain expert. The applied evaluation metrics were precision, recall, f-score, and confidence interval. The results obtained demonstrate that the applied method in the field of Oil Production and Extraction (E&P) is effective, which suggests that it can be used to improve the quality of terminological mappings. The procedure, although adding complexity in its elaboration, can be reproduced in others domains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ontology%20matching" title="ontology matching">ontology matching</a>, <a href="https://publications.waset.org/abstracts/search?q=mapping%20enrichment" title=" mapping enrichment"> mapping enrichment</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20web" title=" semantic web"> semantic web</a>, <a href="https://publications.waset.org/abstracts/search?q=linked%20data" title=" linked data"> linked data</a>, <a href="https://publications.waset.org/abstracts/search?q=SKOS" title=" SKOS"> SKOS</a> </p> <a href="https://publications.waset.org/abstracts/103911/discovering-semantic-links-between-synonyms-hyponyms-and-hypernyms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103911.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">216</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">91</span> Environment and Water in the Conceptions of a Sustainable Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20H.%20Ferreira">Carlos H.

Despite a vast number of documents, technical procedures, and publications involving these themes, conceptions, and even architectural practice are often distanced from critical and methodological reflection on the relationship between environment and architecture. Among the various issues that we could consider in this relationship, we highlight in this article the relevance of water in the environment and in the architectural design. From documentary references and works carried out, we seek contributions to a better systematization and framing of water in architectural thinking. We distinguish, on the one hand, more conceptual issues that involve the environmental relationship of water, involving its cycle, relevance in the landscape, and infrastructural commitments. On the other hand, we highlight a more operative component, focusing on the place of water in the design process, from its perception in space-shape dimensions to more specific technical requirements that involve the interdisciplinary boundaries of architecture. In both approaches to water in architectural design, we seek to contribute to greater sensitivity and efficiency in the art of designing a more sustainable future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainability" title="sustainability">sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=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=resilience%20design" title=" resilience design"> resilience design</a> </p> <a href="https://publications.waset.org/abstracts/134427/environment-and-water-in-the-conceptions-of-a-sustainable-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134427.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">137</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">90</span> Chromium Adsorption by Modified Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Domingos">I.

The removal is very expensive due to the high cost of normal adsorbents. Lignocellulosic materials and mainly treated materials have proven to be a good solution for this problem. Adsorption tests were performed at different pH, different times and with varying concentrations. Results show that is at pH 3 that treated wood absorbs more chromium ranging from 70% (2h treatment) to almost 100% (12 h treatment) much more than untreated wood with less than 40%. Most of the adsorption is made in the first 2-3 hours for untreated and heat treated wood. Modified wood adsorbs more chromium throughout the time. For all the samples, adsorption fitted relatively well the Langmuir model with correlation coefficient ranging from 0.85 to 0.97. The results show that heat treated wood is a good adsorbent ant that this might be a good utilization for sawdust from treating companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20modification" title=" wood modification"> wood modification</a> </p> <a href="https://publications.waset.org/abstracts/11132/chromium-adsorption-by-modified-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11132.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">499</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">89</span> Differences in the Processing of Sentences with Lexical Ambiguity and Structural Ambiguity: An Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariana%20T.%20Teixeira">Mariana T.

Specifically, it aims to verify if there is a difference in processing time between sentences with lexical ambiguity and sentences with structural (or syntactic) ambiguity. We hypothesize, based on the Garden Path Theory, that the two types of ambiguity entail different cognitive efforts, since sentences with structural ambiguity require that two structures be processed, whereas ambiguous phrases whose root of ambiguity is in a word require the processing of a single structure, which admits a variation of punctual meaning, within the scope of only one lexical item. In order to test this hypothesis, 25 undergraduate students, whose average age was 27.66 years, native speakers of Brazilian Portuguese, performed a self-monitoring reading task of ambiguous sentences, which had lexical and structural ambiguity. The results suggest that unambiguous sentence processing is faster than ambiguous sentence processing, whether it has lexical or structural ambiguity. In addition, participants presented a mean reading time greater for sentences with syntactic ambiguity than for sentences with lexical ambiguity, evidencing a greater cognitive effort in sentence processing with structural ambiguity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brazilian%20portuguese" title="Brazilian portuguese">Brazilian portuguese</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20ambiguity" title=" lexical ambiguity"> lexical ambiguity</a>, <a href="https://publications.waset.org/abstracts/search?q=sentence%20processing" title=" sentence processing"> sentence processing</a>, <a href="https://publications.waset.org/abstracts/search?q=syntactic%20ambiguity" title=" syntactic ambiguity"> syntactic ambiguity</a> </p> <a href="https://publications.waset.org/abstracts/85250/differences-in-the-processing-of-sentences-with-lexical-ambiguity-and-structural-ambiguity-an-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85250.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">228</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">88</span> Characterization and Predictors of Paranoid Ideation in Youths</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Sousa">Marina Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9lia%20Barreto%20Carvalho"> Célia Barreto Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolina%20da%20Motta"> Carolina da Motta</a>, <a href="https://publications.waset.org/abstracts/search?q=Joana%20Cabral"> Joana Cabral</a>, <a href="https://publications.waset.org/abstracts/search?q=Vera%20Pereira"> Vera Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Suzana%20Nunes%20Caldeira"> Suzana Nunes Caldeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermelindo%20Peixoto"> Ermelindo Peixoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paranoid ideation is a common thought process that constitutes a defense against perceived social threats. The current study aimed at the characterization of paranoid ideation in youths and to explore the possible predictors involved in the development of paranoid ideations. Paranoid ideation, shame, submission, early childhood memories and current depressive, anxious and stress symptomatology was assessed in a sample of 1516 Portuguese youths. Higher frequencies of paranoid ideation were observed, particularly in females and youths from lower socio-economic status. The main predictors identified relates to submissive behaviors and adverse childhood experiences, and especially to shame feelings. The current study emphasizes that the these predictors are similar to findings in adults and clinical populations, and future implications to research and clinical practice aiming at paranoid ideations are discussed, as well as the pertinence of the study of mediating factors that allow a wider understanding of this thought process in younger populations and the prevention of psychopathology in adulthood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescence" title="adolescence">adolescence</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20memories" title=" early memories"> early memories</a>, <a href="https://publications.waset.org/abstracts/search?q=paranoid%20ideation" title=" paranoid ideation"> paranoid ideation</a>, <a href="https://publications.waset.org/abstracts/search?q=parenting%20styles" title=" parenting styles"> parenting styles</a>, <a href="https://publications.waset.org/abstracts/search?q=shame" title=" shame"> shame</a>, <a href="https://publications.waset.org/abstracts/search?q=submissiveness" title=" submissiveness"> submissiveness</a> </p> <a href="https://publications.waset.org/abstracts/29207/characterization-and-predictors-of-paranoid-ideation-in-youths" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29207.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">500</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">87</span> Mechanical Properties of the Palm Fibers Reinforced HDPE Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniella%20R.%20Mulinari">Daniella R.

The objective is to observe if after the accession of these economies to Mercosur (the first accessions occurred in 1994) these indicators showed better performance, in order to demonstrate if economic integration contributed to improved trade, macroeconomic performance, and level of social and economic development of member countries. To this end, the methodologies used will be a literature review and descriptive statistics. The theoretical framework that guides the work are the theories of Integration: Classical Liberal, Marxist and structural-proactive. The results reveal that most social and economic indicators showed better performance in those economies that joined Mercosur after 1994.

Liquefaction was done with glycerol catalyzed by KOH. Foams were produced following different formulations and using biopolyols from both barks. Subsequently, the foams were characterized according to their mechanical properties and the reaction of the foam formation was monitored by FTIR-ATR. The results show that it is possible to produce polyurethane foams using bio-based polyols and the liquefaction conditions are very important because they influence the characteristics of biopolyols and, consequently the characteristics of the foams.

This type of events can influence the oceanic/land interactions and even be related with climate changes. While the impact of such floods has been fairly studied in the North Atlantic, the impact of analog floods in the North Pacific remains debatable and relatively unknown. Here we will show records of the Missoula floods that have carved the Northwest landscape and have entered the North Pacific through the Columbia River. These records are given by the presence of high (more than 40%) percentages of freshwater diatoms in marine sediments. A regression equation using these percentages allows to estimate by how much the salinities decreased. The timing and impact of North Pacific megafloods recorded in three marine cores of Oregon and California for the past 25000 years (B.P.) will be presented. These records show that the volume of freshwater that entered the North Pacific reached as far as 600 Km south of the Columbia River Mouth, decreasing the salinities by as much as 4 units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=megafloods" title=" megafloods"> megafloods</a>, <a href="https://publications.waset.org/abstracts/search?q=Missoula" title=" Missoula"> Missoula</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Pacific" title=" North Pacific"> North Pacific</a> </p> <a href="https://publications.waset.org/abstracts/103119/timing-and-impacts-of-megafloods-in-the-north-pacific-as-recorded-by-freshwater-diatoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103119.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">172</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">82</span> Mechanical Properties and Thermal Comfort of 3D Printed Hand Orthosis for Neurorehabilitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulo%20H.%20R.%20G.%20Reis">Paulo H.

This technique has a wide possibility of applications in bioengineering, mainly in the manufacture of orthopedic devices, thanks to the versatility of shapes and surface details. The present article aims to evaluate the mechanical viability of a wrist-hand orthosis made using additive manufacturing techniques with Nylon 12 polyamide and compare this device with the wrist-hand orthosis manufactured by the traditional process with thermoplastic Ezeform. The methodology used is based on the application of computational simulations of voltage and temperature, from finite element analysis, in order to evaluate the properties of displacement, mechanical stresses and thermal comfort in the two devices. The execution of this work was carried out through a case study with a 29-year-old male patient. The modeling software involved was Meshmixer from US manufacturer Autodesk and Fusion 360 from the same manufacturer. The results demonstrated that the orthosis developed by 3D printing, from Nylon 12, presents better thermal comfort and response to the mechanical stresses exerted on the orthosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20orthosis" title=" hand orthosis"> hand orthosis</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=neurorehabilitation" title=" neurorehabilitation"> neurorehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/101089/mechanical-properties-and-thermal-comfort-of-3d-printed-hand-orthosis-for-neurorehabilitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101089.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">190</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">81</span> Modes of Seeing in Interactive Exhibitions: A Study on How Technology Can Affect the Viewer and Transform the Exhibition Spaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renata%20P.%20Lopes">Renata P.

The exhibition design through multimedia devices - from the audiovisual to the touch screen - has become a medium from which art can be understood and contemplated. Artistic practices articulated, during the modern period, the spectator's perception in the exhibition space, often challenging the architecture of museums and galleries. In turn, the museum institution seeks to respond to the challenge of welcoming the viewer whose experience is mediated by technological artifacts. When the beholder, together with the technology, interacts with the exhibition space, important displacements happen. In this work, we will analyze the migrations of the exhibition space to the digital environment through mobile devices triggered by the viewer. Based not on technological determinism, but on the conditions of the appearance of this spectator, this work is developed, with the aim of apprehending the way in which technology demarcates the differences between what the spectator was and what becomes in the contemporary atmosphere of the museums and galleries. These notions, we believe, will contribute to the formation of an exhibition design space in conformity with this participant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exhibition" title="exhibition">exhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=museum" title=" museum"> museum</a>, <a href="https://publications.waset.org/abstracts/search?q=exhibition%20design" title=" exhibition design"> exhibition design</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20media" title=" digital media"> digital media</a> </p> <a href="https://publications.waset.org/abstracts/96231/modes-of-seeing-in-interactive-exhibitions-a-study-on-how-technology-can-affect-the-viewer-and-transform-the-exhibition-spaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96231.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">136</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">80</span> A New Family of Flying Wing Low Reynolds Number Airfoils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ciro%20Sobrinho%20Campolina%20Martins">Ciro Sobrinho Campolina Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Halison%20da%20Silva%20Pereira"> Halison da Silva Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitor%20Mainenti%20Leal%20Lopes"> Vitor Mainenti Leal Lopes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unmanned Aerial vehicles (UAVs) has been used in a wide range of applications, from precise agriculture monitoring for irrigation and fertilization to military attack missions. Long range performance is required for many of these applications. Tailless aircrafts are commonly used as long-range configurations and, due to its small amount of stability, the airfoil shape design of its wings plays a central role on the performance of the airplane. In this work, a new family of flying wing airfoils is designed for low Reynolds number flows, typical of small-middle UAVs. Camber, thickness and their maximum positions in the chord are variables used for the airfoil geometry optimization. Aerodynamic non-dimensional coefficients were obtained by the well-established Panel Method. High efficient airfoils with small pitch moment coefficient are obtained from the analysis described and its aerodynamic polars are plotted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airfoil%20design" title="airfoil design">airfoil design</a>, <a href="https://publications.waset.org/abstracts/search?q=flying%20wing" title=" flying wing"> flying wing</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20Reynolds%20number" title=" low Reynolds number"> low Reynolds number</a>, <a href="https://publications.waset.org/abstracts/search?q=tailless%20aircraft" title=" tailless aircraft"> tailless aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a> </p> <a href="https://publications.waset.org/abstracts/33946/a-new-family-of-flying-wing-low-reynolds-number-airfoils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33946.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">629</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">79</span> Development and Validation of the Response to Stressful Situations Scale in the General Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9lia%20Barreto%20Carvalho">Célia Barreto Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolina%20da%20Motta"> Carolina da Motta</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Sousa"> Marina Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Joana%20Cabral"> Joana Cabral</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lu%C3%ADsa%20Carvalho"> Ana Luísa Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermelindo%20Peixoto"> Ermelindo Peixoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the current study was to develop and validate a Response to Stressful Situations Scale (RSSS) for the Portuguese population. This scale assesses the degree of stress experienced in scenarios that can constitute positive, negative and more neutral stressors, and also describes the physiological, emotional and behavioral reactions to those events according to their intensity. These scenario include typical stressor scenarios relevant to patients with schizophrenia, which are currently absent from most scale, assessing specific risks that these stressors may bring on subjects, which may prove useful in non-clinical and clinical populations (i.e. patients with mood or anxiety disorders, schizophrenia). Results from Principal Components Analysis and Confirmatory Factor Analysis of on two adult samples from general population allowed to confirm a three-factor model with good fit indices: χ2 (144)= 370.211, p = 0.000; GFI = 0.928; CFI = 0.927; TLI = 0.914, RMSEA = 0.055, P( rmsea ≤ 0.005) = 0.096; PCFI = 0.781. Further data analysis on the scale revealed that RSSS is an adequate assessment tool of stress response in adults to be used in further research and clinical settings, with good psychometric characteristics, adequate divergent and convergent validity, good temporal stability and high internal consistency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20events" title=" stress events"> stress events</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20response" title=" stress response"> stress response</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20vulnerability" title=" stress vulnerability"> stress vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/29203/development-and-validation-of-the-response-to-stressful-situations-scale-in-the-general-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29203.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">520</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">78</span> New Product Development Typologies: An Analysis of Publications and Citations between 1992 and 2012</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Vilas%20Boas%20Viveiros%20Lopes">Ana Paula Vilas Boas Viveiros Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Marly%20Monteiro%20de%20Carvalho"> Marly Monteiro de Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The new product development for decades has favored companies that can put their products to market quickly and efficiently, providing sustainable competitive advantage difficult to be achieved by their competitors. This paper presents the outcomes of a systematic review of the literature relating to new product development that was published between 1992 and 2012. A hybrid methodological approach that combines bibliometrics, content analysis and semantic analysis was applied. The review discusses the publication patterns, focusing on aspects related to scientific collaboration. The results show that the main academic journal that discusses this theme is “Journal of Product Innovation Management”. Although the first paper relating to this theme was published in 1992, the number of publications on the subject only began to increase substantially in 1999. Most of the studies reviewed in this paper applied qualitative research methods, indicating that most of the research on the theme is still in an exploratory phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=project%20type" title="project type">project type</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20typology" title=" project typology"> project typology</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20product%20development" title=" new product development"> new product development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20competitive%20advantage" title=" sustainable competitive advantage"> sustainable competitive advantage</a> </p> <a href="https://publications.waset.org/abstracts/6850/new-product-development-typologies-an-analysis-of-publications-and-citations-between-1992-and-2012" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6850.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">448</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">77</span> Active Learning Strategies to Develop Student Skills in Information Systems for Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Filomena%20Lopes">Filomena Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Fernandes"> Sandra Fernandes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Active learning strategies are at the center of any change process aimed to improve the development of student skills. This paper aims to analyse the impact of teaching strategies, including problem-based learning (PBL), in the curricular unit of information system for management, based on students’ perceptions of how they contribute to develop the desired learning outcomes of the curricular unit. This course is part of the 1st semester and 3rd year of the graduate degree program in management at a private higher education institution in Portugal. The methodology included an online questionnaire to students (n=40). Findings from students reveal a positive impact of the teaching strategies used. In general, 35% considered that the strategies implemented in the course contributed to the development of courses’ learning objectives. Students considered PBL as the learning strategy that better contributed to enhance the courses’ learning outcomes. This conclusion brings forward the need for further reflection and discussion on the impact of student feedback on teaching and learning processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title="higher education">higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20learning%20strategies" title=" active learning strategies"> active learning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=skills%20development" title=" skills development"> skills development</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20assessment" title=" student assessment"> student assessment</a> </p> <a href="https://publications.waset.org/abstracts/174033/active-learning-strategies-to-develop-student-skills-in-information-systems-for-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174033.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">60</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">76</span> Organizational Climate being Knowledge Sharing Oriented: A Fuzzy-Set Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Lopes%20Henriques">Paulo Lopes Henriques</a>, <a href="https://publications.waset.org/abstracts/search?q=Carla%20Curado"> Carla Curado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to literature, knowledge sharing behaviors are influenced by organizational values and structures, namely organizational climate. The manuscript examines the antecedents of the knowledge sharing oriented organizational climate. According to theoretical expectations the study adopts the following explanatory conditions: knowledge sharing costs, knowledge sharing incentives, perceptions of knowledge sharing contributing to performance and tenure. The study confronts results considering two groups of firms: nondigital (firms without intranet) vs digital (firms with intranet). The paper applies fsQCA technique to analyze data by using fsQCA 2.5 software (www.fsqca.com) testing several conditional arguments to explain the outcome variable. Main results strengthen claims on the relevancy of the contribution of knowledge sharing to performance. Secondly, evidence brings tenure - an explanatory condition that is associated to organizational memory – to the spotlight.

Obtustatin represents the shortest known monomeric disintegrin, isolated from the snake venom of MLO, and is known to specifically inhibit α1β1 integrin. Its oncostatic effect is due to the inhibition of angiogenesis, which likely arises from α1β1 integrin inhibition in the endothelial cells. To explore the therapeutic potential of the MLO snake venom and obtustatin, we studied activity of obtustatin and MLO venom in vitro, by testing their efficacy in human dermal microvascular endothelial cells (HMVEC-D) and in vivo, using chick embryo chorioallantoic membrane assay (CAM assay). Our in vitro results showed that obtustatin in comparison with MLO venom did not exhibit cytotoxic activity in HMVEC-D cells in comparison to MLO venom. But in vivo results have shown that 4µg /embryo (90 µM) of obtustatin inhibited angiogenesis induced by FGF2 by 17% while MLO snake venom induced 22% reduction of the angiogenic index. The concentration of obtustatin in the crude MLO venom was 0.3 nM, which is 300.000 times less than the concentration of the obtustatin itself. Given this enormous difference in concentration, it is likely that some components of the crude venom contribute to the observed anti-angiogenic effect. Hypotheses will be ascertained to justify this action: components in the MLO venom may increase obtustatin efficacy or have independent but synergic anti-angiogenic activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiogenesis" title="angiogenesis">angiogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=alpa1%20beta%201%20integrin" title=" alpa1 beta 1 integrin"> alpa1 beta 1 integrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Macrovipera%20lebetina%20obtusa" title=" Macrovipera lebetina obtusa"> Macrovipera lebetina obtusa</a>, <a href="https://publications.waset.org/abstracts/search?q=obtustatin" title=" obtustatin"> obtustatin</a> </p> <a href="https://publications.waset.org/abstracts/85110/anti-angiogenic-effects-of-the-macrovipera-lebetina-obtusa-snake-crude-venom-and-obtustatin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85110.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">196</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">74</span> Children Beliefs about Illness, Treatments and Vaccines after the Experience of Covid 19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarida%20Maria%20Cabugueira%20Csut%C3%B3dio%20dos%20Santos">Margarida Maria Cabugueira Csutódio dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Joana%20Filipa%20Pint%C3%A9us%20Pereira"> Joana Filipa Pintéus Pereira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The way children understand the concept of health and illness influences their reaction in contexts where these concepts are present (e.g.,illness; vaccination). The recognition of the importance of children's beliefs/representations about health and disease has led to the development of models that seek to explain the development process of these concepts. In the construction of their representations, children are influenced not only by their cognitive competence but also by their life experiences. In the last 3 years, children have experienced a pandemic health crisis that has exposed them to anomalous and stressful situations. Objective: the aim of this study was (1) to identify children’s representations about disease (including symptoms, causes, control/treatment) and prevention (including health procedures and vaccines) and (2) whether COVID19 is mentioned and influences their representations. Methodology: a qualitative study in which 67 children with 7 to 10 years old (mean 8,8) participated. A semi-structured interview was used following the Bibace and Walsh model, focusing on the representation of the disease and its prevention. Results show a marked influence of the lived experience with regard to causes of the disease, disease control and treatment, and adherence to vaccination. Age-dependent differences were found with older children being able to talk about illness and contamination process and younger displaying more basic, concrete and rigid representations.

The study aims to determine young adult’s point of view about cyber pornography viewing, as well as their reasons for engagement, and its effects on them and their relationship with their partner. Interpretative Phenomenological Analysis was used to explore how young adults make sense of cyber pornography viewing. The study focused on Filipino young adults who are in a romantic or married relationship, engage in cyber pornography viewing, and currently residing in Cavite, Philippines. A total of four young adult couples, four females and four males participated in the study as research participants. Data gathered from a total of four young adult couples resulted to a total of nine superordinate themes focusing on (1) exploring young adult couple’s rationales for cyber pornography viewing, (2) experiences of positive effects in engaging to cyber pornography viewing, (3) experiences of negative effects in engaging to cyber pornography viewing, (4) experience of infidelity, (5) experience of necessity, (6) females perception about cyber pornography viewing towards self, (7) males perception about cyber pornography viewing towards self, (8) males perception about cyber pornography viewing towards romantic partner, and (9) males perception about cyber pornography viewing towards others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyberpornography" title="cyberpornography">cyberpornography</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipino" title=" Filipino"> Filipino</a>, <a href="https://publications.waset.org/abstracts/search?q=interpretative%20phenomenological%20analysis" title=" interpretative phenomenological analysis"> interpretative phenomenological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=making%20sense%20of%20cyberpornography" title=" making sense of cyberpornography"> making sense of cyberpornography</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20adult" title=" young adult"> young adult</a> </p> <a href="https://publications.waset.org/abstracts/62378/making-sense-of-cyber-pornography-among-young-adult-couples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62378.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">72</span> Antarctica, Global Change and Deaf Education in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Antonio%20Da%20Costa%20Rodrigues">Luiz Antonio Da Costa Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Mara%20Aparecida%20De%20Castilho%20Lopes"> Mara Aparecida De Castilho Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Santos%20Alencar"> Alexandre Santos Alencar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Teaching of science must transcend simple transmission of fundamental concepts and allow scientific literacy, as a process for understanding the human being as an integral part of a complex and interdependent whole. In this context, approaching the theme ‘Antarctica’ in deaf education is an important advance for teaching, considering that that continent has direct interactions with the climatic and environmental system of the planet. Therefore, textbooks can be important tools to enable the Deaf Community to access the discussion about the natural environment. A specific script was used to analyze textbooks adopted by schools in the Rio de Janeiro Metropolitan Region. Results show that none of the 14 analyzed books have a specific chapter on the theme, some presents images of the continent without reference to their environmental importance, and the complementary texts present in the analyzed material do not address the theme either. It is concluded that the study on Antarctica and global changes in elementary education is still incipient and the material used by most Brazilian public schools does not contemplate that subject in an accessible way for the deaf person. This fact represents the distance between deaf students and their environment, denoting the need for actions to promote that and other neglected themes in Science teaching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antarctica" title="Antarctica">Antarctica</a>, <a href="https://publications.waset.org/abstracts/search?q=deaf%20education" title=" deaf education"> deaf education</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20teaching" title=" science teaching"> science teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=textbook" title=" textbook"> textbook</a> </p> <a href="https://publications.waset.org/abstracts/81264/antarctica-global-change-and-deaf-education-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81264.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">281</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">71</span> Identity Conflict between Social and Business Entrepreneurs: The Challenge of Constructing a Novel Social Identity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rui%20G.%20Ser%C3%B4dio">Rui G.

Specifically, we address how both differentiation and assimilation processes are set of in the context of constructing a novel, distinctive and socially salient – social entrepreneurs. As part of a larger research line, a quasi-experimental study with Social and Business Entrepreneurs, as well as “Lay People” provided evidence consistent with our predictions: (1) Social Entrepreneurs, in contrast with Lay People and Business Entrepreneurs, value more strongly social identity than personal identity, and the later is the only group that values Personal Differentiation; (2) unlike Entrepreneurs, Social Entrepreneurs display an ingroup bias across group evaluations; (3) Lay People, display a self-serving bias, although, overall, they allocate a more positive image to the target groups; (4) combining own vs. others evaluations across all groups, Social Entrepreneurs receive the more positive value. From the standpoint of social identity and self-categorization theories and their approach to group process, we discuss the processes of intergroup comparison and differentiation as core processes in the construction of a positive social identity. We illustrate it within the context of social entrepreneurship, a political and social “wave” that flows across Europe at this time. <p class="card-text"><strong>Keywords:</strong> <a
