The Translog stochastic frontier model was found an appropriate than the Cobb-Douglas model in secondary schools efficiency by ICT Intervention. Based on the results of the Cobb-Douglas model, it is found that the coefficient of the number of teachers, the number of students, and teaching ability had a positive effect on increasing the level of efficiency. It indicated that these are related to technical efficiency. In the case of inefficiency effects for both Cobb-Douglas and Translog models, the coefficient of the ICT lab decreased secondary school inefficiency, but the online class in school was found to increase the level of inefficiency. The coefficients of teacher’s preference for ICT tools like multimedia projectors played a contributor role in decreasing the secondary school inefficiency in the Sylhet division of Bangladesh. The interaction effects of the number of teachers and the classrooms, and the number of students and the number of classrooms, the number of students and teaching ability, and the classrooms and teaching ability of the teachers were recorded with the positive values and these have a positive impact on increasing the secondary school efficiency. The overall mean efficiency of urban secondary schools was found at 84.66% for the Translog model, while it was 83.63% for the Cobb-Douglas model. The overall mean efficiency of rural secondary schools was found at 80.98% for the Translog model, while it was 81.24% for the Cobb-Douglas model. So, the urban secondary schools performed better than the rural secondary schools in the Sylhet division. It is observed from the results of the Tobit model that the teacher-student ratio had a positive influence on secondary school efficiency. The teaching experiences of those who have 1 to 5 years and 10 years above, MPO type school, conventional teaching method have had a negative and significant influence on secondary school efficiency. The estimated value of σ-square (0.0625) was different from Zero, indicating a good fit. The value of γ (0.9872) was recorded as positive and it can be interpreted as follows: 98.72 percent of random variation around in secondary school outcomes due to inefficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency" title="efficiency">efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20schools" title=" secondary schools"> secondary schools</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT" title=" ICT"> ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20frontier%20analysis" title=" stochastic frontier analysis"> stochastic frontier analysis</a> </p> <a href="https://publications.waset.org/abstracts/148681/efficiency-of-secondary-schools-by-ict-intervention-in-sylhet-division-of-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148681.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">152</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">83</span> Gender Cultural Scripts and Career Choices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Hoorn">Caroline Hoorn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Post-matriculants in disadvantaged communities such as Douglas encounter a number of career challenges. The transition to the democratic dispensation in 1994, coupled with the rapid changes in the information domain that are characteristic of post-industrial life, complicate the career development trajectories of disadvantaged youth. The career development stories and experiences of disadvantaged youth in provinces such as the Northern Cape have not been told, leading to their marginalisation. It is against this background that the study explored the gendered dimensions of career development narratives, experiences, and choices of post-matriculants in the Douglas community in the Northern Cape. Using a qualitative, narrative approach, the researcher elicited career development stories from 23 participants in Douglas using semi-structured interviews. Two main themes were highlighted through the narratives; (1) willingness to challenge the traditional male dominated career script (2) breaking gender barriers. The study showed that gender did not have any influence on the career choices of the post-matriculants. The perceptions around career choices and gender were being challenged partly by the urge to affirm equality and the constant reminder of the poverty-stricken conditions prevalent in the households. A preferred gender is not required to be attached to the fulfilment of outcomes in a knowledge-based economy. Thus, it is not an issue of gender or masculinity but knowledge and skills. Furthermore, the study revealed that the career choices being considered are still the traditionally stereotypical careers like nursing, teaching, and social work, which demonstrates a lack of information to a broader pool of career options to select from. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=career%20development" title="career development">career development</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=narratives" title=" narratives"> narratives</a>, <a href="https://publications.waset.org/abstracts/search?q=post-matriculants" title=" post-matriculants"> post-matriculants</a> </p> <a href="https://publications.waset.org/abstracts/159795/gender-cultural-scripts-and-career-choices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159795.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">101</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> Best Responses for the Dynamic Model of Hotel Room Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Tran">Xuan Tran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to present a comprehensive dynamic model for pricing strategies in the hotel competition to find a win-win situation for the competitive set. By utilizing the Cobb-Douglas utility model, the study establishes room rates by analyzing the price elasticity of demand across a competitive set of four hotels, with a focus on occupancy rates. To further enhance the analysis, game theory is applied to identify the best response for each competitive party, which illustrates the optimal pricing strategy for each hotel in the competitive landscape. This approach offers valuable insights into how hotels can strategically adjust their room rates in response to market conditions and competitor actions. The primary contributions of this research include as follows: (1) advantages for both individual hotels and the broader competitive hotel market, (2) benefits for hotel management overseeing multiple brands, and (3) positive impacts on the local community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20model" title="dynamic model">dynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title=" game theory"> game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20response" title=" best response"> best response</a>, <a href="https://publications.waset.org/abstracts/search?q=Cobb-Douglas" title=" Cobb-Douglas"> Cobb-Douglas</a> </p> <a href="https://publications.waset.org/abstracts/190235/best-responses-for-the-dynamic-model-of-hotel-room-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190235.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">22</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> Spatio-temporal Variations in Heavy Metal Concentrations in Sediment of Qua Iboe River Estuary, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justina%20I.%20R.%20Udotong">Justina I.

A preliminary survey to determine the four sampling stations along the river continuum showed that the area spanned between < 0.1% salinity at the control station and 21.5‰ at the fourth station along the river continuum. A preliminary survey to determine the four sampling locations along the river estuary showed variations in salinity and other physicochemical parameters. The estuary was found to be polluted with heavy metals from point and nonpoint sources at varying degrees. Mean values of 7.80 mg/kg, 4.97 mg/kg and 2.80 mg/kg of nickel were obtained for sediment samples from Douglas creek, Qua Iboe and Atlantic sampling locations, respectively in the dry season. The wet season nickel concentrations were however lower. The entire study area was grossly contaminated by iron. At Douglas creek, the concentration of iron in sediment was 9274 ± 9.54 mg/kg while copper, nickel, lead and vanadium were <0.5 mg/kg each as compared to iron. Bioaccumulation was therefore suspected within the study area as values of 31.00 ± 0.79, 36.00 ± 0.10 and 55.00 ± 0.05 mg/kg of zinc were recorded in sediment at Douglas creek, Atlantic and the control sampling locations. The results from this study showed that the source of these heavy metals were from point sources like the corrosion of metal steel pipes from old bridges as well as oily sludge wastes from the Qua Iboe Terminal / tank farm located within the vicinity of the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title="heavy metal">heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=Qua%20Iboe%20River%20estuary" title=" Qua Iboe River estuary"> Qua Iboe River estuary</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20variations" title=" seasonal variations"> seasonal variations</a>, <a href="https://publications.waset.org/abstracts/search?q=Sediment" title=" Sediment"> Sediment</a> </p> <a href="https://publications.waset.org/abstracts/31121/spatio-temporal-variations-in-heavy-metal-concentrations-in-sediment-of-qua-iboe-river-estuary-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31121.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">371</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 Deletion-Cost Based Fast Compression Algorithm for Linear Vector Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiuxiao%20Chen">Qiuxiao Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Hou"> Yan Hou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ning%20Wu"> Ning Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As there are deficiencies of the classic Douglas-Peucker Algorithm (DPA), such as high risks of deleting key nodes by mistake, high complexity, time consumption and relatively slow execution speed, a new Deletion-Cost Based Compression Algorithm (DCA) for linear vector data was proposed. For each curve — the basic element of linear vector data, all the deletion costs of its middle nodes were calculated, and the minimum deletion cost was compared with the pre-defined threshold. If the former was greater than or equal to the latter, all remaining nodes were reserved and the curve’s compression process was finished. Otherwise, the node with the minimal deletion cost was deleted, its two neighbors' deletion costs were updated, and the same loop on the compressed curve was repeated till the termination. By several comparative experiments using different types of linear vector data, the comparison between DPA and DCA was performed from the aspects of compression quality and computing efficiency. Experiment results showed that DCA outperformed DPA in compression accuracy and execution efficiency as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Douglas-Peucker%20algorithm" title="Douglas-Peucker algorithm">Douglas-Peucker algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20vector%20data" title=" linear vector data"> linear vector data</a>, <a href="https://publications.waset.org/abstracts/search?q=compression" title=" compression"> compression</a>, <a href="https://publications.waset.org/abstracts/search?q=deletion%20cost" title=" deletion cost"> deletion cost</a> </p> <a href="https://publications.waset.org/abstracts/8376/a-deletion-cost-based-fast-compression-algorithm-for-linear-vector-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8376.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">251</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> Carbon Sequestering and Structural Capabilities of Eucalyptus Cloeziana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Holly%20Sandberg">Holly Sandberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Christina%20McCoy"> Christina McCoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Mansy"> Khaled Mansy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eucalyptus Cloeziana, commonly known as Gympie Messmate, is a fast-growing hardwood native to Australia. Its quick growth makes it advantageous for carbon sequestering, while its strength class lends itself to structural applications. Market research shows that the demand for timber is growing, especially mass timber. An environmental product declaration, or EPD, for eucalyptus Cloeziana in the Australian market has been evaluated and compared to the EPD’s of steel and Douglas fir of the same region. An EPD follows a product throughout its life cycle, stating values for global warming potential, ozone depletion potential, acidification potential, eutrophication potential, photochemical ozone creation potential, and abiotic depletion potential. This paper highlights the market potential, as well as the environmental benefits and challenges to using Gympie Messmate as a structural building material. In addition, a case study is performed to compare steel, Douglas fir, and eucalyptus in terms of embodied carbon and structural weight within a single structural bay. Comparisons among the three materials highlight both the differences in structural capabilities as well as environmental impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eucalyptus" title="eucalyptus">eucalyptus</a>, <a href="https://publications.waset.org/abstracts/search?q=timber" title=" timber"> timber</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=structural" title=" structural"> structural</a>, <a href="https://publications.waset.org/abstracts/search?q=material" title=" material"> material</a> </p> <a href="https://publications.waset.org/abstracts/142348/carbon-sequestering-and-structural-capabilities-of-eucalyptus-cloeziana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142348.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">78</span> Antioxidant Characteristics of Serbian Conifers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dubravka%20%C5%A0tajner">Dubravka Štajner</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20M.%20Popovi%C4%87"> Boris M.

Present article highlights an antioxidant capacity of Serbian conifer plants. Antioxidant activities of the crude extracts were assessed using different assays. In this study, quantities of phenolic compounds (total phenols, flavonoids, tannins and proanthocyanidins), contents of photosynthetic pigments (chlorophyll a and b and carotenoids), soluble proteins and proline were examined. MDA quantities and ability of extracts to remove reactive nitrogen and oxygen species (RNOS) were also investigated. Furthermore, antioxidant activities of extracts against DPPH∙, ferric reducing antioxidant power, permanganate reducing antioxidant capacity were also determined. According to almost all used assays, antioxidant and scavenging capacities of silver fir (Abies alba Mill.), and Douglas fir (Pseudotsuga menziesii) were superior compared to spruce. Presented results implicated that leaves of Douglas fir and silver fir possessed outstanding antioxidant characteristics that could diminish damage caused by oxygen radicals which are responsible for many of the bodily changes and susceptibility to different diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conifers" title="conifers">conifers</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=reducing%20power" title=" reducing power"> reducing power</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a> </p> <a href="https://publications.waset.org/abstracts/3414/antioxidant-characteristics-of-serbian-conifers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3414.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">348</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> Study of Cahn-Hilliard Equation to Simulate Phase Separation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nara%20Guimar%C3%A3es">Nara Guimarães</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Aquino%20Martorano"> Marcelo Aquino Martorano</a>, <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Gouv%C3%AAa"> Douglas Gouvêa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An investigation into Cahn-Hilliard equation was carried out through numerical simulation to identify a possible phase separation for one and two dimensional domains.

The key reason is the function's characteristics to describe the actual production using inputs like labour and capital. The characteristics of the function like returns to scale, marginal, and diminishing marginal productivities are covered in the introductory units in both microeconomics and macroeconomics with a 2-dimensional static visualisation of the function. However, less insight is provided regarding three-dimensional surface, changes in the curvature properties due to returns to scale, the linkage of the short-run production function with its long-run counterpart and marginal productivities, the level curves, and the constraint optimisation. Since (freshman) learners have diverse prior knowledge and cognitive skills, the existing “one size fits all” approach is not very helpful. The aim of this study is to bridge this gap by introducing technological intervention with interactive animations of the three-dimensional surface and sequential unveiling of the characteristics mentioned above using Python software. A small classroom intervention has helped students enhance their analytical and visualisation skills towards active and authentic learning of this topic. However, to authenticate the strength of our approach, a quasi-Delphi study will be conducted to ask domain-specific experts, “What value to the learning process in economics is there using a 2-dimensional static visualisation compared to using a 3-dimensional dynamic visualisation?’ Here three perspectives of the intervention were reviewed by a panel comprising of novice students, experienced students, novice instructors, and experienced instructors in an effort to determine the learnings from each type of visualisations within a specific domain of knowledge. The value of this approach is key to suggesting different pedagogical methods which can enhance learning outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cobb-douglas%20production%20function" title="cobb-douglas production function">cobb-douglas production function</a>, <a href="https://publications.waset.org/abstracts/search?q=quasi-Delphi%20method" title=" quasi-Delphi method"> quasi-Delphi method</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20teaching%20and%20learning" title=" effective teaching and learning"> effective teaching and learning</a>, <a href="https://publications.waset.org/abstracts/search?q=3D-visualisations" title=" 3D-visualisations"> 3D-visualisations</a> </p> <a href="https://publications.waset.org/abstracts/142864/a-perspective-on-teaching-mathematical-concepts-to-freshman-economics-students-using-3d-visualisations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142864.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">145</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">75</span> Marginal Productivity of Small Scale Yam and Cassava Farmers in Kogi State, Nigeria: Data Envelopment Analysis as a Complement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Ojo">M.

Ogaji </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study examined marginal productivity analysis of small scale yam and cassava farmers in Kogi State, Nigeria. Data used for the study were obtained from primary source using a multi-stage sampling technique with structured questionnaires administered to 150 randomly selected yam and cassava farmers from three Local Government Areas of the State. Description statistics, data envelopment analysis and Cobb-Douglas production function were used to analyze the data. The DEA result on the overall technical efficiency of the farmers showed that 40% of the sampled yam and cassava farmers in the study area were operating at frontier and optimum level of production with mean technical efficiency of 1.00. This implies that 60% of the yam and cassava farmers in the study area can still improve their level of efficiency through better utilization of available resources, given the current state of technology. The results of the Cobb-Douglas analysis of factors affecting the output of yam and cassava farmers showed that labour, planting materials, fertilizer and capital inputs positively and significantly affected the output of the yam and cassava farmers in the study area. The study further revealed that yam and cassava farms in the study area operated under increasing returns to scale. This result of marginal productivity analysis further showed that relatively efficient farms were more marginally productive in resource utilization This study also shows that estimating production functions without separating the farms to efficient and inefficient farms bias the parameter values obtained from such production function. It is therefore recommended that yam and cassava farmers in the study area should form cooperative societies so as to enable them have access to productive inputs that will enable them expand. Also, since using a single equation model for production function produces a bias parameter estimates as confirmed above, farms should, therefore, be decomposed into efficient and inefficient ones before production function estimation is done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marginal%20productivity" title="marginal productivity">marginal productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=DEA" title=" DEA"> DEA</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20function" title=" production function"> production function</a>, <a href="https://publications.waset.org/abstracts/search?q=Kogi%20state" title=" Kogi state"> Kogi state</a> </p> <a href="https://publications.waset.org/abstracts/35444/marginal-productivity-of-small-scale-yam-and-cassava-farmers-in-kogi-state-nigeria-data-envelopment-analysis-as-a-complement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35444.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">483</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> Public Spending and Economic Growth: An Empirical Analysis of Developed Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bernur%20Acikgoz">Bernur Acikgoz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to investigate the effects of public spending on economic growth and examine the sources of economic growth in developed countries since the 1990s.

Through the reallocation of aid in agriculture, implementation of an education-for-education model, and provision of access to market information to the women in rural regions, the retraction of both the supply and international demand curves of trafficked humans is possible; resulting in the shutdown of the market as a whole.

Therefore, this paper focuses on finding such starting points that will optimize the results of RDP algorithm. Specifically, this paper proposes a curve approximation algorithm that finds flat points, called essential points, of an input curve, divides the curve into corner-like sub-curves using the essential points, and applies the RDP algorithm to the sub-curves. The number of essential points play a role on optimizing the approximation results by balancing the degree of shape information loss and the amount of data reduction. Through experiments with curves of various types and complexities of shape, we compared the performance of the proposed algorithm with three other methods, i.e., the RDP algorithm itself and its variants. As a result, the proposed algorithm outperformed the others in term of maintaining the original shapes of the input curve, which is important in various applications like pattern recognition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curve%20approximation" title="curve approximation">curve approximation</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20point" title=" essential point"> essential point</a>, <a href="https://publications.waset.org/abstracts/search?q=RDP%20algorithm" title=" RDP algorithm"> RDP algorithm</a> </p> <a href="https://publications.waset.org/abstracts/29359/an-optimized-rdp-algorithm-for-curve-approximation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29359.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">535</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> A Formal Approach for Instructional Design Integrated with Data Visualization for Learning Analytics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Douglas%20A.%20Menezes">Douglas A.

To this end, the study empirically scrutinised the roles of organisational leadership in delivering sustainable construction. The study adopted a quantitative approach while construction professionals formed the population of the study. A well-articulated questionnaire was used in eliciting responses from the respondents, while appropriate methods of data analysis were used. Findings from the study depicted that the major role of organisational leadership in the delivery of sustainable construction is acting as sustainability integrators. Equally revealed are the internal and external factors affecting organisational leadership in delivering sustainable construction.

Since the GMPEs frequently model the peak ground acceleration (PGA) the goal of the present study was to refit a selection of 44 of the existing equation models for PGA in light of the latest data. The algorithm Levenberg-Marquardt was used for fitting the coefficients of the equations and the results are evaluated both quantitatively by presenting the root mean squared error (RMSE) and qualitatively by drawing graphs of the five best fitted equations. The RMSE was found to be as low as 0.08 for the best equation models. The newly estimated coefficients vary from the values published in the original works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ground%20Motion%20Prediction%20Equations" title="Ground Motion Prediction Equations">Ground Motion Prediction Equations</a>, <a href="https://publications.waset.org/abstracts/search?q=Levenberg-Marquardt%20algorithm" title=" Levenberg-Marquardt algorithm"> Levenberg-Marquardt algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=refitting%20PF-L%20database" title=" refitting PF-L database"> refitting PF-L database</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20ground%20acceleration" title=" peak ground acceleration"> peak ground acceleration</a> </p> <a href="https://publications.waset.org/abstracts/15426/refitting-equations-for-peak-ground-acceleration-in-light-of-the-pf-l-database" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15426.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">462</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">66</span> The Regional Center for Business Quality of the University Center of the Valleys: Transiting to an Entrepreneurial University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Alberto%20Santamaria%20Velasco">Carlos Alberto Santamaria Velasco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study object of this chapter analyzes the case of the Centro Regional para la Calidad Empresarial (CreCE) starting from an analysis of the theoretical discussion about the universities as actors of the development and generation of enterprises.

The core discussion groups of our sample are very gender balanced, with female alters slightly outnumbering male alters. However, the core discussion groups are racially homogenous, consisting of mostly white students (around or above 80 percent).

Scott</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Allemande from J. S. Bach's Partita for solo flute (BWV 1013) presents many unique challenges for any flautist, especially in terms of segmentation analysis required to select breathing places in the first half. Without claiming to identify a 'correct' solution to this problem, this paper analyzes the section in terms of a set of techniques based around a statistical property commonly (if not ubiquitously) found in music, namely Zipf’s law. Specifically, the paper considers violations of this expected profile at various levels of analysis, an approach which has yielded interesting insights in previous studies. The investigation is then grounded by considering four actual solutions to the problem found in recordings made by different flautists, which opens up the possibility of expanding Zipfian analysis to include a consideration of inter-onset-intervals (IOIs). It is found that significant deviations from the expected Zipfian distributions can reveal and highlight stylistic choices made by different performers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter-onset-interval" title="inter-onset-interval">inter-onset-interval</a>, <a href="https://publications.waset.org/abstracts/search?q=Partita%20for%20solo%20flute" title=" Partita for solo flute"> Partita for solo flute</a>, <a href="https://publications.waset.org/abstracts/search?q=BWV%201013" title=" BWV 1013"> BWV 1013</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation%20analysis" title=" segmentation analysis"> segmentation analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Zipf%E2%80%99s%20law" title=" Zipf’s law"> Zipf’s law</a> </p> <a href="https://publications.waset.org/abstracts/92755/some-observations-on-the-analysis-of-four-performances-of-the-allemande-from-js-bachs-partita-for-solo-flute-bwv-1013-in-terms-of-zipfs-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92755.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">183</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">63</span> New Perspectives on Musician’s Focal Dystonia Causes and Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Shabe">Douglas Shabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The world of the performing musician is one of high pressure that comes from the expected high standards they have to live up to and that they expect from themselves. The pressure that musicians put themselves under can manifest itself in physical problems such as focal dystonia. Knowledge of the contributing factors and potential rehabilitation strategies cannot only give players hope for recovery but also the information to prevent it from happening in the first place. This dissertation presents a multiple case study of two performing brass musicians who developed focal dystonia of the embouchure, also known as embouchure dystonia, combined with an autoethnography of the author’s experience of battling embouchure dystonia and our attempts at recovery. Extensive research into the current state of focal dystonia research was done to establish a base of knowledge. That knowledge was used to develop interview questions for the two participants and interpret the findings of the qualitative data collected. The research knowledge, as well as the qualitative data from the case studies, was also used to interpret the author’s experience. The author determined that behavioral, environmental, and psychological factors were of prime importance in the subjects’ development of focal dystonia and that modifications of those factors are essential for the best chance at recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=focal%20dystonia" title="focal dystonia">focal dystonia</a>, <a href="https://publications.waset.org/abstracts/search?q=embouchure%20dystonia" title=" embouchure dystonia"> embouchure dystonia</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20teaching%20and%20learning" title=" music teaching and learning"> music teaching and learning</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20education" title=" music education"> music education</a> </p> <a href="https://publications.waset.org/abstracts/165014/new-perspectives-on-musicians-focal-dystonia-causes-and-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165014.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">85</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">62</span> Intentional Relationship Building: Stem Faculty Perceptions of Culturally Responsive Mentoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niesha%20Douglas">Niesha Douglas</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Merriweather"> Lisa Merriweather</a>, <a href="https://publications.waset.org/abstracts/search?q=Cathy%20Howell"> Cathy Howell</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Sancyzk"> Anna Sancyzk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many studies explain that mentoring in an academic setting contributes to student success and retention. However, in the United States, where the population is diverse and filled with multiple ethnic groups, mentoring has become too generalized and fails to offer a unique individualized experience for underrepresented minorities (URM). The purpose of this paper is to describe the findings of an ongoing qualitative study that investigates the relationships among STEM doctoral faculty and URM students. Several faculty from three different predominately white institutions (PWI) in the Southeastern region of the United States were interviewed and engaged in open dialogue about their experiences with mentoring. The data collection included semi-structured interviews that took place in the classroom (pre-COVID-19) as well as virtually. The theoretical framework draws on the idea of Critical Race Theory and how cultural, social constructs interfere with effective mentoring for URM Doctoral STEM students. The findings in this study suggest that though the faculty and several years of experience mentoring students, there were some gaps in understanding the needs of URM students and how mentoring is a unique relationship that should be specialized for each student and should not fit into one mold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=culture" title="culture">culture</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20race%20theory" title=" critical race theory"> critical race theory</a>, <a href="https://publications.waset.org/abstracts/search?q=mentoring" title=" mentoring"> mentoring</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM" title=" STEM"> STEM</a> </p> <a href="https://publications.waset.org/abstracts/137217/intentional-relationship-building-stem-faculty-perceptions-of-culturally-responsive-mentoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137217.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">198</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">61</span> Onmanee Prajuabjinda, Pakakrong Thondeeying, Jipisute Chunthorng-Orn, Bhanuz Dechayont, Arunporn Itharat </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekrem%20Erdem">Ekrem Erdem</a>, <a href="https://publications.waset.org/abstracts/search?q=Can%20Tansel%20Tugcu"> Can Tansel Tugcu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improved resource efficiency of production is a key requirement for sustainable growth, worldwide. In this regards, by considering the energy and tourism as the extra inputs to the classical Coub-Douglas production function, this study aims at investigating the efficiency changes in the North African countries. To this end, the study uses panel data for the period 1995-2010 and adopts the Malmquist index based on the data envelopment analysis. Results show that tourism increases technical and scale efficiencies, while it decreases technological and total factor productivity changes. On the other hand, when the production function is augmented by the energy input, technical efficiency change decreases, while the technological change, scale efficiency change and total factor productivity change increase. Thus, in order to satisfy the needs for sustainable growth, North African governments should take some measures for increasing the contribution that the tourism makes to economic growth and some others for efficient use of resources in the energy sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20envelopment%20analysis" title="data envelopment analysis">data envelopment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20efficiency" title=" economic efficiency"> economic efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20African%20countries" title=" North African countries"> North African countries</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20growth" title=" sustainable growth"> sustainable growth</a> </p> <a href="https://publications.waset.org/abstracts/27371/onmanee-prajuabjinda-pakakrong-thondeeying-jipisute-chunthorng-orn-bhanuz-dechayont-arunporn-itharat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27371.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">343</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">60</span> Combined Influence of Charge Carrier Density and Temperature on Open-Circuit Voltage in Bulk Heterojunction Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Yeboah">Douglas Yeboah</a>, <a href="https://publications.waset.org/abstracts/search?q=Monishka%20Narayan"> Monishka Narayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jai%20Singh"> Jai Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the key parameters in determining the power conversion efficiency (PCE) of organic solar cells (OSCs) is the open-circuit voltage, however, it is still not well understood. In order to examine the performance of OSCs, it is necessary to understand the losses associated with the open-circuit voltage and how best it can be improved. Here, an analytical expression for the open-circuit voltage of bulk heterojunction (BHJ) OSCs is derived from the charge carrier densities without considering the drift-diffusion current. The open-circuit voltage thus obtained is dependent on the donor-acceptor band gap, the energy difference between the highest occupied molecular orbital (HOMO) and the hole quasi-Fermi level of the donor material, temperature, the carrier density (electrons), the generation rate of free charge carriers and the bimolecular recombination coefficient. It is found that open-circuit voltage increases when the carrier density increases and when the temperature decreases. The calculated results are discussed in view of experimental results and agree with them reasonably well. Overall, this work proposes an alternative pathway for improving the open-circuit voltage in BHJ OSCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20carrier%20density" title="charge carrier density">charge carrier density</a>, <a href="https://publications.waset.org/abstracts/search?q=open-circuit%20voltage" title=" open-circuit voltage"> open-circuit voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20solar%20cells" title=" organic solar cells"> organic solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/68927/combined-influence-of-charge-carrier-density-and-temperature-on-open-circuit-voltage-in-bulk-heterojunction-organic-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68927.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">373</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">59</span> The Hitchhiker’s Guide to the Galaxy: The Challenges of Translating Science Fiction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esteban%20Tremoco">Esteban Tremoco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article aims to highlight some specificities of translating Science Fiction (SF literature) and, more particularly, its comic subgenre. Translating SF presupposes the translation of neologisms and gadget names of all kinds, while the translation of humor sometimes implies a need for the translator to slightly modify certain scenes or situations. In the French translation of Douglas Adams' Hitchhiker's Guide to the Galaxy by Jean Bonnefoy (Guide du routard galactique, 1982), the humorous dimension of the book is enhanced through certain choices made by the translator. One of the striking aspects of this translation is that almost all of the characters’ names have been translated, which is not the case in the German, Italian, Spanish and Portuguese translations. While there may be translations of characters’ names outside of the SF literature, there is no denying that by translating them, Jean Bonnefoy added a humorous layer to Adams' work. This work belongs to science fiction literature thanks to gadgets resulting from futuristic technological innovations, but also the presence of space travel, extra-terrestrials and mysterious worlds, which are central elements in SF. These names of planets, aliens, and other gadgets have also been translated, adapted, or at least reinvented, by Jean Bonnefoy in order to amuse the French-speaking readership. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=translation" title="translation">translation</a>, <a href="https://publications.waset.org/abstracts/search?q=translation%20studies" title=" translation studies"> translation studies</a>, <a href="https://publications.waset.org/abstracts/search?q=humour" title=" humour"> humour</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20fiction" title=" science fiction"> science fiction</a> </p> <a href="https://publications.waset.org/abstracts/167393/the-hitchhikers-guide-to-the-galaxy-the-challenges-of-translating-science-fiction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167393.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">82</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">58</span> Modelling of Organic Rankine Cycle for Waste Heat Recovery Process in Supercritical Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jahedul%20Islam%20Chowdhury">Jahedul Islam Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Bao%20Kha%20Nguyen"> Bao Kha Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Thornhill"> David Thornhill</a>, <a href="https://publications.waset.org/abstracts/search?q=Roy%20Douglas"> Roy Douglas</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Glover"> Stephen Glover</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organic Rankine Cycle (ORC) is the most commonly used method for recovering energy from small sources of heat. The investigation of the ORC in supercritical condition is a new research area as it has a potential to generate high power and thermal efficiency in a waste heat recovery system. This paper presents a steady state ORC model in supercritical condition and its simulations with a real engine’s exhaust data. The key component of ORC, evaporator, is modelled using finite volume method, modelling of all other components of the waste heat recovery system such as pump, expander and condenser are also presented. The aim of this paper is to investigate the effects of mass flow rate and evaporator outlet temperature on the efficiency of the waste heat recovery process. Additionally, the necessity of maintaining an optimum evaporator outlet temperature is also investigated. Simulation results show that modification of mass flow rate is the key to changing the operating temperature at the evaporator outlet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Organic%20Rankine%20cycle" title="Organic Rankine cycle">Organic Rankine cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20condition" title=" supercritical condition"> supercritical condition</a>, <a href="https://publications.waset.org/abstracts/search?q=steady%20state%20model" title=" steady state model"> steady state model</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20heat%20recovery" title=" waste heat recovery"> waste heat recovery</a> </p> <a href="https://publications.waset.org/abstracts/26813/modelling-of-organic-rankine-cycle-for-waste-heat-recovery-process-in-supercritical-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26813.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">405</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">57</span> Compromising Relevance for Elegance: A Danger of Dominant Growth Models for Backward Economies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Givi%20Kupatadze">Givi Kupatadze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Backward economies are facing a challenge of achieving sustainable high economic growth rate. Dominant growth models represent a roadmap in framing economic development strategy. This paper examines a relevance of the dominant growth models for backward economies. Cobb-Douglas production function, the Harrod-Domar model of economic growth, the Solow growth model and general formula of gross domestic product are examined to undertake a comprehensive study of the dominant growth models. Deductive research method allows to uncover major weaknesses of the dominant growth models and to come up with practical implications for economic development strategy. The key finding of the paper shows, contrary to what used to be taught by textbooks of economics, that constant returns to scale property of the dominant growth models are a mere coincidence and its generalization over space and time can be regarded as one of the most unfortunate mistakes in the whole field of political economy. The major suggestion of the paper for backward economies is that understanding and considering taxonomy of economic activities based on increasing and diminishing returns to scale represent a cornerstone of successful economic development strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=backward%20economies"
