A structural equation model is also applied to determine the indicators and relationships that exist between the observed environmental changes and the quality of life. Using survey data to model the results, a value of 0.382 is derived as the vulnerability level for San Pedro, where values closer to zero indicates lower vulnerability and values closer to one indicates higher vulnerability. The results showed the social pillar to be most vulnerable, with the indicator ‘participation’ ranked the highest in its cohort. Although, the environmental pillar is ranked as least vulnerable, the indicators ‘hazard’ and ‘biodiversity’ obtained scores closer to 0.4, suggesting that changes in the environment are occurring from natural and anthropogenic activities. These changes can negatively influence the quality of life as illustrated in the structural equation modelling. The study concludes by reporting on the need for collective action and participation by households in lowering vulnerability to ensure sustainable development and livelihood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=participation" title=" participation"> participation</a>, <a href="https://publications.waset.org/abstracts/search?q=San%20Pedro" title=" San Pedro"> San Pedro</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20equation%20model" title=" structural equation model"> structural equation model</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability%20index" title=" vulnerability index"> vulnerability index</a> </p> <a href="https://publications.waset.org/abstracts/34964/assessing-the-vulnerability-level-in-coastal-communities-in-the-caribbean-a-case-study-of-san-pedro-belize" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34964.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">631</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">270</span> Quantitative and Qualitative Analysis of Randomized Controlled Trials in Physiotherapy from India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Hariohm">K.

It is essential to determine the production and quality of the clinical trials from India since, it may reflect the scientific growth of the profession. These trends can be taken as a baseline to measure our performance and also can be used as a guideline for the future trials. Objective: To quantify and analyze qualitatively the RCT’s from India from the period 2000-2013’ May, and classify data for the information process. Methods: Studies were searched in the Medline database using the key terms “India”, “Indian”, “Physiotherapy”. Clinical trials only with PT authors were included. Trials out of scope of PT practice and on animals were excluded. Retrieved valid articles were analyzed for published year, type of participants, area of study, PEDro score, outcome measure domains of impairment, activity, participation; ‘a priori’ sample size calculation, region, and explanation of the intervention. Result: 45 valid articles were retrieved from the year 2000-2013’ May. The majority of articles were done on symptomatic participants (81%). The frequencies of conditions repeated more were low back pain (n-7) and diabetes (n-4). PEDro score with mode 5 and upper limit of 8 and lower limit 4 was found. 97.2% of studies measure the outcome at the impairment level, 34% in activity level, and 27.8% in participation level. 29.7% of studies did ‘a priori’ sample size calculation. Correlation of year trend and PEDro score found to be not significant (p>.05). Individual PEDro item analysis showed, randomization (100%), concealment (33%) baseline (76%), blinding-subject, therapist, assessor (9.1%, 0%, 10%), follow-up (89%) ITT (15%), statistics between groups (100%), measures of variance (88 %). Conclusion: The trend shows an upward slope in terms of RCTs published from India which is a good indicator. The qualitative analysis showed some gaps in the clinical trial design, which can be expected to be, fulfilled by the future researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RCT" title="RCT">RCT</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDro" title=" PEDro"> PEDro</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20therapy" title=" physical therapy"> physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/4227/quantitative-and-qualitative-analysis-of-randomized-controlled-trials-in-physiotherapy-from-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4227.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">341</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">269</span> Multidisciplinary and Multilevel Design Methodology of Unmanned Aerial Vehicles using Enhanced Collaborative Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20F.%20Albuquerque">Pedro F.

Current sunglasses standards establish safe limits regarding lens transmittance in the 280 nm to 380 nm range. However, frames are additionally relevant in protecting the eyes from ultraviolet exposure. This study involves the use of a prototype that simulates backscattered light environments and quantifies the contribution of the frame as a function of the light that reaches the eye when wearing sunglasses. The prototype consists of an LED illuminated sphere, a mannequin head with optical sensors, and baseline and measurements are performed. A set of 29 samples was tested, and results show the variation of light blocking presented by different types of frames, ranging from 68% to 80%. This is still ongoing research. Prototype improvements for allowing albedo simulation, as well as the six types of sky simulation, are being implemented to show the intensity of UV light reaching the eye for several environments worldwide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sunglasses%20standards" title="sunglasses standards">sunglasses standards</a>, <a href="https://publications.waset.org/abstracts/search?q=sunglasses%20frame" title=" sunglasses frame"> sunglasses frame</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20protection" title=" ultraviolet protection"> ultraviolet protection</a>, <a href="https://publications.waset.org/abstracts/search?q=albedo" title=" albedo"> albedo</a> </p> <a href="https://publications.waset.org/abstracts/163501/sunglasses-frame-uv-protection-beyond-lens-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163501.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">103</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">267</span> Fuzzy Expert Systems Applied to Intelligent Design of Data Centers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20M.%20Figueroa%20de%20la%20Cruz">Mario M.

During MT, a mirror is placed between the two upper limbs (UL), thus reflecting movements of the non- affected side as if it were the affected side. Objectives: The aim of this review is to analyze the evidence on the effec.tiveness of MT in the recovery of UL function in population with post chronic stroke. Methods: The literature search was carried out in PubMed, ISI Web of Science, and PEDro database. Inclusion criteria: a) studies that include individuals diagnosed with stroke for at least 6 months; b) intervention with MT in UL or comparing it with other interventions; c) articles published until 2023; d) articles published in English or Portuguese; e) randomized controlled studies. Exclusion criteria: a) animal studies; b) studies that do not provide a detailed description of the intervention; c) Studies using central electrical stimulation. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. Studies with < 4 on PEDro scale were excluded. Eighteen studies met all the inclusion criteria. Main results and conclusions: The quality of the studies varies between 5 and 8. One article compared muscular strength training (MST) with MT vs without MT and four articles compared the use of MT vs conventional therapy (CT), one study compared extracorporeal shock therapy (EST) with and without MT and another study compared functional electrical stimulation (FES), MT and biofeedback, three studies compared MT with Mesh Glove (MG) or Sham Therapy, five articles compared performing bimanual exercises with and without MT and three studies compared MT with virtual reality (VR) or robot training (RT). The assessment of changes in function and structure (International Classification of Functioning, Disability and Health parameter) was carried out, in each article, mainly using the Fugl Meyer Assessment-Upper Limb scale, activity and participation (International Classification of Functioning, Disability and Health parameter) were evaluated using different scales, in each study. The positive results were seen in these parameters, globally. Results suggest that MT is more effective than other therapies in motor recovery and function of the affected UL, than these techniques alone, although the results have been modest in most of the included studies. There is also a more significant improvement in the distal movements of the affected hand than in the rest of the UL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20therapy" title="physical therapy">physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=mirror%20therapy" title=" mirror therapy"> mirror therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20stroke" title=" chronic stroke"> chronic stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20limb" title=" upper limb"> upper limb</a>, <a href="https://publications.waset.org/abstracts/search?q=hemiplegia" title=" hemiplegia"> hemiplegia</a> </p> <a href="https://publications.waset.org/abstracts/181912/perspectives-and-challenges-a-functional-bread-with-yeast-extract-to-improve-human-diet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181912.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">53</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">262</span> Key Transfer Protocol Based on Non-invertible Numbers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20A.%20Lizama-Perez">Luis A.

The possibility of the use of experiments with didactic wind tunnels can facilitate the education of future professionals. The objective of this proposal is the development of a low-cost aerodynamic balance to be used in a didactic wind tunnel. The set is comprised of an Arduino microcontroller, programmed by an open source software, linked to load cells built by students from another project. The didactic wind tunnel is 5,0m long and the test area is 90,0 cm x 90,0 cm x 150,0 cm. The Weq® electric motor, model W-22 of 9,2 HP, moves a fan with nine blades, each blade 32,0 cm long. The Weq® frequency inverter, model WEGCFW 08 (Vector Inverter) is responsible for wind speed control and also for the motor inversion of the rotational direction. A flat-convex profile prototype of airfoil was tested by measuring the drag and lift forces for certain attack angles; the air flux conditions remained constant, monitored by a Pitot tube connected to a EXTECH® Instruments digital pressure differential manometer Model HD755. The results indicate a good agreement with the theory. The choice of all of the components of this proposal resulted in a low-cost product providing a high level of specific knowledge of mechanics of fluids, which may be a good alternative to teaching in countries with scarce educational resources. The system also allows the expansion to measure other parameters like fluid velocity, temperature, pressure as well as the possibility of automation of other functions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20balance" title="aerodynamic balance">aerodynamic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title=" wind tunnel"> wind tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20gauge" title=" strain gauge"> strain gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20cell" title=" load cell"> load cell</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino" title=" Arduino"> Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost%20education" title=" low-cost education"> low-cost education</a> </p> <a href="https://publications.waset.org/abstracts/51909/affordable-aerodynamic-balance-for-instrumentation-in-a-wind-tunnel-using-arduino" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51909.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">258</span> A Low Cost Education Proposal Using Strain Gauges and Arduino to Develop a Balance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thais%20Cavalheri%20Santos">Thais Cavalheri Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Jose%20Gabriel%20Ferreira"> Pedro Jose Gabriel Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Daliberto%20Frugoli"> Alexandre Daliberto Frugoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucio%20Leonardo"> Lucio Leonardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Americo%20Frugoli"> Pedro Americo Frugoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a low cost education proposal to be used in engineering courses. The engineering education in universities of a developing country that is in need of an increasing number of engineers carried out with quality and affordably, pose a difficult problem to solve. In Brazil, the political and economic scenario requires academic managers able to reduce costs without compromising the quality of education. Within this context, the elaboration of a physics principles teaching method with the construction of an electronic balance is proposed. First, a method to develop and construct a load cell through which the students can understand the physical principle of strain gauges and bridge circuit will be proposed. The load cell structure was made with aluminum 6351T6, in dimensions of 80 mm x 13 mm x 13 mm and for its instrumentation, a complete Wheatstone Bridge was assembled with strain gauges of 350 ohms. Additionally, the process involves the use of a software tool to document the prototypes (design circuits), the conditioning of the signal, a microcontroller, C language programming as well as the development of the prototype. The project also intends to use an open-source I/O board (Arduino Microcontroller). To design the circuit, the Fritizing software will be used and, to program the controller, an open-source software named IDE®. A load cell was chosen because strain gauges have accuracy and their use has several applications in the industry. A prototype was developed for this study, and it confirmed the affordability of this educational idea. Furthermore, the goal of this proposal is to motivate the students to understand the several possible applications in high technology of the use of load cells and microcontroller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arduino" title="Arduino">Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20cell" title=" load cell"> load cell</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost%20education" title=" low-cost education"> low-cost education</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20gauge" title=" strain gauge"> strain gauge</a> </p> <a href="https://publications.waset.org/abstracts/51943/a-low-cost-education-proposal-using-strain-gauges-and-arduino-to-develop-a-balance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51943.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">303</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">257</span> Prosthesis Design for Bilateral Hip Disarticulation Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Plaza">Mauricio Plaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Willian%20Aperador"> Willian Aperador</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hip disarticulation is an amputation through the hip joint capsule, removing the entire lower extremity, with a closure of the remaining musculature over the exposed acetabulum.

In parallel, the maintenance activities have also been increasing in consequence of ageing and deterioration of the wind farms. The time available for wind blade maintenance is given by the weather window that is based upon weather conditions. Most of the wind blade repair and maintenance activities require a narrow window of temperature and humidity. Due to this limitation, the current weather windows result only on approximately 35% days/year are used for maintenance, that takes place mostly during summertime. This limitation creates large economic losses in the energy production of the wind towers, since they can be inoperative or with the energy production output reduced for days or weeks due to existing damages. Another important aspect is that the maintenance costs are higher due to the high standby time and seasonality imposed on the technicians. To reduce the relevant maintenance costs of blades and energy loses some technological developments were carried out to significantly improve this reality. The focus of this activity was to develop a series of key developments to have in the near future a suspended access equipment that can operate in harsh conditions, wind rain, cold/hot environment. To this end we have identified key areas that need to be revised and require new solutions to be found; a habitat system, multi-configurable roof and floor, roof and floor interface to blade, secondary attachment solutions to the blade and to the tower. On this paper we will describe the advances produced during a national R&D project made in partnership with an end-user (Onrope) and a test center (ISQ). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20maintenance" title="wind turbine maintenance">wind turbine maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20reduction" title=" cost reduction"> cost reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20innovations" title=" technological innovations"> technological innovations</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20blade" title=" wind turbine blade"> wind turbine blade</a> </p> <a href="https://publications.waset.org/abstracts/150262/technological-developments-to-reduce-wind-blade-turbine-levelized-cost-of-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150262.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">92</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">254</span> Solar Cell Using Chemical Bath Deposited PbS:Bi3+ Films as Electron Collecting Layer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Chavez%20Portillo">Melissa Chavez Portillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Pacio%20Castillo"> Mauricio Pacio Castillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hector%20Juarez%20Santiesteban"> Hector Juarez Santiesteban</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Portillo%20Moreno"> Oscar Portillo Moreno </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chemical bath deposited PbS:Bi3+ as an electron collection layer is introduced between the silicon wafer and the Ag electrode the performance of the PbS heterojunction thin film solar thin film solar cells with 1 cm2 active area.

As the number of PV systems increases, some issues affecting grid operations have been identified. This paper studied the impacts related to changes in solar irradiance on a distribution/sub-transmission network, considering variations due to moving clouds and daily cycles. Using MATLAB/Simulink software, a solar farm of 30 MWp was built and then implemented to a test network. From simulations, it has been determined that irradiance changes can have a significant impact on the grid by causing voltage fluctuations outside the allowable thresholds. This work discussed some local control strategies and grid reinforcements to mitigate the negative effects of the irradiance changes on the grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reactive%20power%20control" title="reactive power control">reactive power control</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20irradiance" title=" solar irradiance"> solar irradiance</a>, <a href="https://publications.waset.org/abstracts/search?q=utility-scale%20PV%20systems" title=" utility-scale PV systems"> utility-scale PV systems</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20fluctuations" title=" voltage fluctuations"> voltage fluctuations</a> </p> <a href="https://publications.waset.org/abstracts/44539/dynamic-performance-analysis-of-distribution-sub-transmission-networks-with-high-penetration-of-pv-generation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44539.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">460</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">252</span> The Effectiveness of Concept Mapping as a Tool for Developing Critical Thinking in Undergraduate Medical Education: A BEME Systematic Review: BEME Guide No. 81</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Fonseca">Marta Fonseca</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Marv%C3%A3o"> Pedro Marvão</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Oliveira"> Beatriz Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Heleno"> Bruno Heleno</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Carreiro-Martins"> Pedro Carreiro-Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20Neuparth"> Nuno Neuparth</a>, <a href="https://publications.waset.org/abstracts/search?q=Ant%C3%B3nio%20Rendas"> António Rendas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Concept maps (CMs) visually represent hierarchical connections among related ideas. They foster logical organization and clarify idea relationships, potentially aiding medical students in critical thinking (to think clearly and rationally about what to do or what to believe). However, there are inconsistent claims about the use of CMs in undergraduate medical education. Our three research questions are: 1) What studies have been published on concept mapping in undergraduate medical education? 2) What was the impact of CMs on students’ critical thinking? 3) How and why have these interventions had an educational impact? Methods: Eight databases were systematically searched (plus a manual and an additional search were conducted). After eliminating duplicate entries, titles, and abstracts, and full-texts were independently screened by two authors. Data extraction and quality assessment of the studies were independently performed by two authors. Qualitative and quantitative data were integrated using mixed-methods. The results were reported using the structured approach to the reporting in healthcare education of evidence synthesis statement and BEME guidance. Results: Thirty-nine studies were included from 26 journals (19 quantitative, 8 qualitative and 12 mixed-methods studies). CMs were considered as a tool to promote critical thinking, both in the perception of students and tutors, as well as in assessing students’ knowledge and/or skills. In addition to their role as facilitators of knowledge integration and critical thinking, CMs were considered both teaching and learning methods. Conclusions: CMs are teaching and learning tools which seem to help medical students develop critical thinking. This is due to the flexibility of the tool as a facilitator of knowledge integration, as a learning and teaching method. The wide range of contexts, purposes, and variations in how CMs and instruments to assess critical thinking are used increase our confidence that the positive effects are consistent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concept%20map" title="concept map">concept map</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20education" title=" medical education"> medical education</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate" title=" undergraduate"> undergraduate</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title=" critical thinking"> critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=meaningful%20learning" title=" meaningful learning"> meaningful learning</a> </p> <a href="https://publications.waset.org/abstracts/172812/the-effectiveness-of-concept-mapping-as-a-tool-for-developing-critical-thinking-in-undergraduate-medical-education-a-beme-systematic-review-beme-guide-no-81" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172812.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">251</span> Wash Fastness of Textile Fibers Dyed with Natural Dye from Eucalyptus Wood Steaming Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ticiane%20Rossi">Ticiane Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maur%C3%ADcio%20C.%20Ara%C3%BAjo"> Maurício C.

The suggestion is made that a hotel’s fair treatment (in terms of distributive, procedural, and interactional justice) toward customers will be appreciated by the employees, who will reciprocate in kind by favouring the hotel with increased customer-oriented behaviours (COBs). Data were collected from 204 employees at eight upscale hotels in the Canary Islands (Spain). Unlike in the case of perceptions of distributive justice, results of structural equation modelling demonstrate that employees substantively react to interactional and procedural justice toward guests by engaging in customer-oriented behaviours (COBs). The findings offer new reasons why employees decide to engage in COBs, and they highlight potentially beneficial effects of fair treatment toward guests bring to hospitality through promoting COBs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hotel%20guests%E2%80%99%20%28mis%29%20treatment" title="hotel guests’ (mis) treatment">hotel guests’ (mis) treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=customer-oriented%20behaviours" title=" customer-oriented behaviours"> customer-oriented behaviours</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20citizenship" title=" employee citizenship"> employee citizenship</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20justice" title=" organizational justice"> organizational justice</a>, <a href="https://publications.waset.org/abstracts/search?q=third-party%20observers" title=" third-party observers"> third-party observers</a>, <a href="https://publications.waset.org/abstracts/search?q=third-party%20intervention" title=" third-party intervention"> third-party intervention</a> </p> <a href="https://publications.waset.org/abstracts/4384/the-organizational-justice-citizenship-behavior-link-in-hotels-does-customer-orientation-matter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4384.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">273</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">247</span> Multidimensional Item Response Theory Models for Practical Application in Large Tests Designed to Measure Multiple Constructs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Fernanda%20Ordo%C3%B1ez%20Martinez">Maria Fernanda Ordoñez Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alvaro%20Mauricio%20Montenegro"> Alvaro Mauricio Montenegro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents a statistical methodology for measuring and founding constructs in Latent Semantic Analysis.

The methodology is applied in a set of real semantic data presenting impressive results for the coherence, speed and precision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=semantic%20analysis" title="semantic analysis">semantic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=factorial%20analysis" title=" factorial analysis"> factorial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=dimension%20reduction" title=" dimension reduction"> dimension reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=penalized%20logistic%20regression" title=" penalized logistic regression"> penalized logistic regression</a> </p> <a href="https://publications.waset.org/abstracts/42128/multidimensional-item-response-theory-models-for-practical-application-in-large-tests-designed-to-measure-multiple-constructs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42128.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">246</span> The Presence of Carnism on Portuguese Television</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rui%20Pedro%20Fonseca">Rui Pedro Fonseca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the results of a research about carnism on Portuguese television. It begins by presenting a case study of MasterChef program (TVI) which conveys carnism in both practices and language, and from which some characteristics of their dominant representations are described. Subsequently, the paper presents the indicators of the presence of carnism in the Portuguese television programming, between 2013 and 2014, in the TVI, RTP1, and SICS channels. The data reveals that there is the hegemony of the carnist ideology in the main channels of the Portuguese television. Also, the samples collected and viewed show no mention of the impacts of carnism in its various dimensions (non-human animals, environment, human health and sustainability). <p
