The hospitality sector is particularly affected where it has been claimed two thirds of workers earn less than the living wage. The UK Government is set to introduce (April 2016) a national living wage (NLW) which is therefore likely to have a significant impact on the hospitality sector. To date limited data exists that focus on how hotels are tackling the issue, what stakeholder perceptions are towards the change in legislation, and how the NLW may affect working patterns in the sector. This study draws on interviews with a range of key stakeholders such as hotel HR and general managers as well as industry representatives to explore these issues within the broader context of responsible tourism. Data collection is still ongoing and is scheduled to be completed by the end of June 2016. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hospitality" title="hospitality">hospitality</a>, <a href="https://publications.waset.org/abstracts/search?q=living%20wage" title=" living wage"> living wage</a>, <a href="https://publications.waset.org/abstracts/search?q=responsible%20tourism" title=" responsible tourism"> responsible tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20employment" title=" tourism employment"> tourism employment</a> </p> <a href="https://publications.waset.org/abstracts/49640/the-impact-of-a-living-wage-on-the-uk-hotel-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49640.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">383</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">35</span> Coprophagus Beetles (Scarabaeidae: Coleoptera) of Buxa Tiger Reserve, West Bengal, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subhankar%20Kumar%20Sarkar">Subhankar Kumar Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scarab beetles composing the family Scarabaeidae is one of the largest families in the order Coleoptera. The family is comprised of 11 subfamilies. Of these, the subfamily Scarabaeinae includes 13 tribes globally. Indian species are however considered within 2 tribes Scarabaeini and Coprini. Scarab beetles under this subfamily also known as Coprophagus beetles play an indispensable role in forestry and agriculture. Both adults and larvae of these beetles do a remarkable job of carrying excrement into the soil thus enriching the soil to a great extent. Eastern and North Eastern states of India are heavily rich in diversity of organisms as this region exhibits the tropical rain forests of the eastern Himalayas, which exhibits one of the 18 biodiversity hotspots of the world and one of the three of India. Buxa Tiger Reserve located in Dooars between latitudes 26°30” to 26°55” North & longitudes 89°20” to 89°35” East is one such fine example of rain forests of the eastern Himalayas. Despite this, the subfamily is poorly known, particularly from this part of the globe and demands serious revisionary studies. It is with this background; the attempt is being made to assess the Scarabaeinae fauna of the forest. Both extensive and intensive surveys were conducted in different beats under different ranges of Buxa Tiger Reserve. For collection sweep nets, bush beating and collection in inverted umbrella, hand picking techniques were used. Several pit fall traps were laid in the collection localities of the Reserve to trap ground dwelling scarabs. Dung of various animals was also examined to make collections. In the evening hours UV light, trap was used to collect nocturnal beetles. The collected samples were studied under Stereozoom Binocular Microscopes Zeiss SV6, SV11 and Olympus SZ 30. The faunistic investigation of the forest revealed in the recognition of 19 species under 6 genera distributed over 2 tribes. Of these Heliocopris tyrannus Thomson, 1859 was recorded new from the Country, while Catharsius javanus Lansberge, 1886, Copris corpulentus Gillet, 1910, C. doriae Harold, 1877 and C. sarpedon Harold, 1868 from the state. 4 species are recorded as endemic to India. The forest is dominated by the members of the Genus Onthophagus, of which Onthophagus (Colobonthophagus) dama (Fabricius, 1798) is represented by highest number of individuals. Their seasonal distribution is most during Premonsoon followed by Monsoon and Postmonsoon. Zoogeographically all the recorded species are of oriental distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buxa%20tiger%20reserve" title="buxa tiger reserve">buxa tiger reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20records" title=" new records"> new records</a>, <a href="https://publications.waset.org/abstracts/search?q=scarabaeinae" title=" scarabaeinae"> scarabaeinae</a>, <a href="https://publications.waset.org/abstracts/search?q=scarabaeidae" title=" scarabaeidae"> scarabaeidae</a> </p> <a href="https://publications.waset.org/abstracts/53401/coprophagus-beetles-scarabaeidae-coleoptera-of-buxa-tiger-reserve-west-bengal-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53401.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">241</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">34</span> Economic Conflict between the United Kingdom and the European Community 1945-1975 </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soumia%20Hebbri">Soumia Hebbri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between Britain and the European Union is phenomenally complex with a great opposition to Europe in the British Conservative and Labour Parties emerged since 1945.

Britain then applied to join the EEC in 1961 under Harold Macmillan’s Conservative Government, its application led by the Chief Negotiator Edward Heath. This application was vetoed by President de Gaulle. With de Gaulle out of power Britain. finally could joined in 1973.

In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addition of the traditional mordanting agents and then submitted to wash fastness analysis. The resulting dyed fabrics were evaluated for color fastness. It was found that wash fastness of dyed fabrics was very good to cotton and excellent to nylon and wool. <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=natural%20dye" title=" natural dye"> natural dye</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20fibers" title=" textile fibers"> textile fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=wash%20fastness" title=" wash fastness"> wash fastness</a> </p> <a href="https://publications.waset.org/abstracts/25681/wash-fastness-of-textile-fibers-dyed-with-natural-dye-from-eucalyptus-wood-steaming-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25681.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">614</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">32</span> Rhetoric and Renarrative Structure of Digital Images in Trans-Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Geng">Yang Geng</a>, <a href="https://publications.waset.org/abstracts/search?q=Anqi%20Zhao"> Anqi Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The misreading theory of Harold Bloom provides a new diachronic perspective as an approach to the consistency between rhetoric of digital technology, dynamic movement of digital images and uncertain meaning of text. Reinterpreting the diachroneity of 'intertextuality' in the context of misreading theory extended the range of the 'intermediality' of transmedia to the intense tension between digital images and symbolic images throughout history of images. With the analogy between six categories of revisionary ratios and six steps of digital transformation, digital rhetoric might be illustrated as a linear process reflecting dynamic, intensive relations between digital moving images and original static images. Finally, it was concluded that two-way framework of the rhetoric of transformation of digital images and reversed served as a renarrative structure to revive static images by reconnecting them with digital moving images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhetoric" title="rhetoric">rhetoric</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20art" title=" digital art"> digital art</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediality" title=" intermediality"> intermediality</a>, <a href="https://publications.waset.org/abstracts/search?q=misreading%20theory" title=" misreading theory"> misreading theory</a> </p> <a href="https://publications.waset.org/abstracts/100230/rhetoric-and-renarrative-structure-of-digital-images-in-trans-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100230.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">256</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">31</span> Environmental Engineering Case Study of Waste Water Treatement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20Jideofor">Harold Jideofor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wastewater treatment consists of applying known technology to improve or upgrade the quality of a wastewater. Usually wastewater treatment will involve collecting the wastewater in a central, segregated location (the Wastewater Treatment Plant) and subjecting the wastewater to various treatment processes. Most often, since large volumes of wastewater are involved, treatment processes are carried out on continuously flowing wastewaters (continuous flow or "open" systems) rather than as "batch" or a series of periodic treatment processes in which treatment is carried out on parcels or "batches" of wastewaters. While most wastewater treatment processes are continuous flow, certain operations, such as vacuum filtration, involving storage of sludge, the addition of chemicals, filtration and removal or disposal of the treated sludge, are routinely handled as periodic batch operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title="wastewater treatment">wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20engineering" title=" environmental engineering"> environmental engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water" title=" waste water"> waste water</a> </p> <a href="https://publications.waset.org/abstracts/14980/environmental-engineering-case-study-of-waste-water-treatement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14980.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">586</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">30</span> Proactive Pure Handoff Model with SAW-TOPSIS Selection and Time Series Predict</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20V%C3%A1squez">Harold Vásquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Hern%C3%A1ndez"> Cesar Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Ingrid%20P%C3%A1ez"> Ingrid Páez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper approach cognitive radio technic and applied pure proactive handoff Model to decrease interference between PU and SU and comparing it with reactive handoff model.

The model showed better performance was TOPSIS-MA, although TOPSIS-AR had a higher predictive ability this was not reflected in the interference reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20radio" title="cognitive radio">cognitive radio</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum%20handoff" title=" spectrum handoff"> spectrum handoff</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series" title=" time series"> time series</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20networks" title=" wireless networks"> wireless networks</a> </p> <a href="https://publications.waset.org/abstracts/33216/proactive-pure-handoff-model-with-saw-topsis-selection-and-time-series-predict" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33216.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">487</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">29</span> Utilizing the Principal Component Analysis on Multispectral Aerial Imagery for Identification of Underlying Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Bosques-Perez">Marcos Bosques-Perez</a>, <a href="https://publications.waset.org/abstracts/search?q=Walter%20Izquierdo"> Walter Izquierdo</a>, <a href="https://publications.waset.org/abstracts/search?q=Harold%20Martin"> Harold Martin</a>, <a href="https://publications.waset.org/abstracts/search?q=Liangdon%20Deng"> Liangdon Deng</a>, <a href="https://publications.waset.org/abstracts/search?q=Josue%20Rodriguez"> Josue Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Thony%20Yan"> Thony Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Cabrerizo"> Mercedes Cabrerizo</a>, <a href="https://publications.waset.org/abstracts/search?q=Armando%20Barreto"> Armando Barreto</a>, <a href="https://publications.waset.org/abstracts/search?q=Naphtali%20Rishe"> Naphtali Rishe</a>, <a href="https://publications.waset.org/abstracts/search?q=Malek%20Adjouadi"> Malek Adjouadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aerial imagery is a powerful tool when it comes to analyzing temporal changes in ecosystems and extracting valuable information from the observed scene. It allows us to identify and assess various elements such as objects, structures, textures, waterways, and shadows. To extract meaningful information, multispectral cameras capture data across different wavelength bands of the electromagnetic spectrum. In this study, the collected multispectral aerial images were subjected to principal component analysis (PCA) to identify independent and uncorrelated components or features that extend beyond the visible spectrum captured in standard RGB images. The results demonstrate that these principal components contain unique characteristics specific to certain wavebands, enabling effective object identification and image segmentation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=multispectral" title=" multispectral"> multispectral</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a> </p> <a href="https://publications.waset.org/abstracts/170875/utilizing-the-principal-component-analysis-on-multispectral-aerial-imagery-for-identification-of-underlying-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170875.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">176</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">28</span> Engineering Management and Practice in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20Jideofor">Harold Jideofor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The application of Project Management (PM) tools and techniques in the public sector is gradually becoming an important issue in developing economies, especially in a country like Nigeria where projects of different size and structures are undertaken. The paper examined the application of the project management practice in the public sector in Nigeria. The PM lifecycles, tools, and techniques were presented. The study was carried out in Lagos because of its metropolitan nature and rapidly growing economy. Twenty-three copies of questionnaire were administered to 23 public institutions in Lagos to generate primary data. The descriptive analysis techniques using percentages and table presentations coupled with the coefficient of correlation were used for data analysis. The study revealed that application of PM tools and techniques is an essential management approach that tends to achieve specified objectives within specific time and budget limits through the optimum use of resources. Furthermore, the study noted that there is a lack of in-depth knowledge of PM tools and techniques in public sector institutions sampled, also a high cost of the application was also observed by the respondents. The study recommended among others that PM tools and techniques should be applied gradually especially in old government institutions where resistance to change is perceived to be high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=project%20management" title="project management">project management</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sector" title=" public sector"> public sector</a>, <a href="https://publications.waset.org/abstracts/search?q=practice" title=" practice"> practice</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/15217/engineering-management-and-practice-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15217.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">342</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">27</span> Maintenance Management Practice for Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20Jideofor%20Nnachetam">Harold Jideofor Nnachetam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maintenance management in Nigeria Polytechnic faced many issues due to poor service delivery, inadequate finance, and poor maintenance plan and maintenance backlogs. The purpose of this study is to improve the conventional method practices which tend to be ineffective in Nigeria Polytechnic. The case study was conducted with eight Polytechnics in Nigeria. The selected Polytechnic is based on conventional method practices and its major problems, attempt to implement computerized technology and the willingness of staff to share their experiences. All feedbacks from respondents through semi-structured interview were recorded using video camera and transcribed verbatim. The overall findings of this research indicated; poor service delivery, inadequate financial, poor maintenance planning and maintenance backlogs. There is also need to overcome less man power competencies of maintenance management practices which existed with all eight Polytechnics. In addition, the study also found that the Polytechnics still use conventional maintenance management processes in managing building facility condition. As a result, the maintenance management staff was not able to improve the maintenance management performance at the Polytechnics. The findings are intended to be used for maintenance management practices at Nigeria Polytechnics in order to provide high-quality of building facility with safe and healthy environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maintenance%20management" title="maintenance management">maintenance management</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20method" title=" conventional method"> conventional method</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20management%20system" title=" maintenance management system"> maintenance management system</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria%20polytechnic" title=" Nigeria polytechnic"> Nigeria polytechnic</a> </p> <a href="https://publications.waset.org/abstracts/33471/maintenance-management-practice-for-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33471.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">322</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">26</span> The Influence of Swirl Burner Geometry on the Sugar-Cane Bagasse Injection and Burning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Harold%20Sosa-Arnao">Juan Harold Sosa-Arnao</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Jos%C3%A9%20de%20Oliveira%20Ferreira"> Daniel José de Oliveira Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Caice%20Guarato%20Santos"> Caice Guarato Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Justo%20Em%C3%ADlio%20Alvarez"> Justo Emílio Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Paes%20Rangel"> Leonardo Paes Rangel</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Won%20Park"> Song Won Park </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A comprehensive CFD model is developed to represent heterogeneous combustion and two burner designs of supply sugar-cane bagasse into a furnace.

The over dependence on the traditional biomass has brought in a number of negative consequences on people’s health and the environment. To curb the situation, the Government of Malawi (GoM), through its national policy of 2018 and charcoal strategies of 2007, identified biogas as a suitable alternative energy source for cooking. The GoM intends to construct tubular digesters across the country and one of the most crucial factors is the availability of livestock manure. The study was conducted to assess biogas potential from livestock manure by using Quantum Geographic information system (QGIS) software. Potential methane was calculated based on the population of livestock, amount of manure produced per capita and year, total solids, biogas yield and availability coefficient. The results of the study estimated biogas potential at 687 million m3 /year. Districts identified with highest biogas potential were Lilongwe, Ntcheu, Mangochi, Neno, Mwanza, Blantyre, Chiradzulu and Mulanje. The information will help investors and the Government of Malawi to locate potential sites for biogas plants installation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=feedstock" title=" feedstock"> feedstock</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock" title=" livestock"> livestock</a> </p> <a href="https://publications.waset.org/abstracts/155174/evaluation-of-biogas-potential-from-livestock-in-malawi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155174.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">174</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">24</span> Effects of Net Height of Crab Entangling Nets on the Capture of Targeted Economically Important Portunid Species and Non-Target Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizalyn%20Gonzales">Rizalyn Gonzales</a>, <a href="https://publications.waset.org/abstracts/search?q=Harold%20Monteclaro"> Harold Monteclaro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study determined the effects of net height on the capture performance of crab entangling nets. Fishing trials were conducted using nets with the following net heights: 1) 12 meshes down (MD), 2) 24 MD and 3) 50 MD. A total of 1,290 individuals comprising of 87 species belonging to 53 families were caught. One-way ANOVA showed that net height significantly affects various catch parameters such as catch per unit effort (CPUE) of the total and target catch, amount of non-target catch, sizes and species richness. The use of appropriate net height is a potential technical measure for a selective but still efficient crab entangling net fishery. Lower net height significantly reduced non-target catch up to 70%. While lower nets decreased the CPUE of target catch such as blue swimming crab Portunus pelagicus and christian crab Charybdis feriatus up to 65% in 12 MD, catch in 24 MD was not significantly different with that in 50 MD. The use of 24 MD also resulted in capturing larger-sized Portunus pelagicus. Catch species richness decreased up to 58% in lower nets. These results are useful to fisheries managers and government institutions to develop or improve existing regulations towards a sustainable crab fishery particularly blue swimming crabs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blue%20swimming%20crabs" title="blue swimming crabs">blue swimming crabs</a>, <a href="https://publications.waset.org/abstracts/search?q=catch%20per%20unit%20effort" title=" catch per unit effort"> catch per unit effort</a>, <a href="https://publications.waset.org/abstracts/search?q=crab%20entangling%20nets" title=" crab entangling nets"> crab entangling nets</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20height" title=" net height"> net height</a> </p> <a href="https://publications.waset.org/abstracts/73921/effects-of-net-height-of-crab-entangling-nets-on-the-capture-of-targeted-economically-important-portunid-species-and-non-target-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73921.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">220</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">23</span> The Role of Questioning Techniques in a Literature Classroom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Magallona">Barbara Magallona</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given the observations between students who were active participants in a dialogue with their teacher and students who simply answered the teacher’s questions, the researcher will investigate the relationship between student-teacher dialogue in the classroom and the development of higher level thinking skills with an emphasis on the questioning techniques used by the teacher. The study posits the main question: What is the relationship between teachers’ questioning techniques and the development of students’ higher level thinking skills in a literature class (or in literature classes) in Xavier? The following are the study’s sub-questions: a) What types of questions do literature teachers at Xavier School ask? b) What types of responses do literature students at Xavier School give to teachers' questions? c) To what extent is the development of students' higher level thinking skills shown in teacher-student classroom dialogues in Xavier School's literature classroom? Since questioning techniques and student responses in the literature classroom form the core of this paper and in order to evaluate them, the study uses Andersen and Krathwohl’s revision of Harold Bloom’s Taxonomy of Educational Objectives.

The reason of its importance has been discussed frequently since the rise of Michel Foucault and his vantage point toward the circulation of power and the transgression of forces. The language and society act as the basic grounds for the study, as all human beings are bound to the set of rules and norms which shape them in the acceptable way in the macrocosm. How different genders in different positions behave and show reactions to the provocation of social forces and superiority of one another, is of great interest to writers and literary critics. Mamet’s works are noticeable for their controversial but timely themes which illustrate the human conflict with the community and greed for power. Many critics like Christopher Bigsby and Harold Bloom have been discussing Mamet and his ideas during recent years. This paper is the study of Oleanna, Mamet’s masterpiece about teacher-student relationship and the circulation of power between a man and woman. He shows the very breakable boundaries in domination of a gender and the downfall of speech as the consequence of transgression and freedom. The failure of the language the teacher uses and the abuses of his own words by a student who seeks superiority and knowledge are the main subjects of discussion. Supported by the ideas of Foucault, the language Mamet uses to represent his characters becomes the fundamental element of this survey. As a result, language becomes both the means of achievement and also downfall. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=domination" title="domination">domination</a>, <a href="https://publications.waset.org/abstracts/search?q=foucault" title=" foucault"> foucault</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a>, <a href="https://publications.waset.org/abstracts/search?q=mamet" title=" mamet"> mamet</a>, <a href="https://publications.waset.org/abstracts/search?q=oleanna" title=" oleanna"> oleanna</a>, <a href="https://publications.waset.org/abstracts/search?q=power" title=" power"> power</a>, <a href="https://publications.waset.org/abstracts/search?q=transgression" title=" transgression"> transgression</a> </p> <a href="https://publications.waset.org/abstracts/24942/under-the-veneer-of-words-lies-power-foucauldian-analysis-of-oleanna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24942.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">485</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">21</span> Ideological and Poetological Tensions: Wu Mi’s Enterprise of Imitating and Translating George Gordon Byron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanjin%20Yan">Hanjin Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The English Romantic George Gordon Byron (1788-1824) was widely celebrated by men of letters in early republican China as a Satanic freedom fighter challenging classical poetics and traditional values. However, Wu Mi (1894-1978), the most persistent critic of contemporary iconoclasm, perceived Byron as a paragon of self-righteous poet-exiles who maintained moral integrity and achieved poetic excellence during times of frustration, just like canonized classical Chinese poets. Wu Mi not only composed lengthy imitations of the third canto of Byron’s Childe Harold’s Pilgrimage (1816) but also patronized a rendering of the canto. Taking André Lefevere’s rewriting theory as a framework, this paper explores the interplay of ideology and poetics by examining Wu Mi’s imitations against Byron’s original and its Chinese translation patronized by Wu Mi. Textual analysis shows that Wu Mi’s approach to Byron’s poetry was informed not only by his endeavor to invigorate classical Chinese poetics, but also by his program to preserve China’s cultural traditions and integrate Western new humanism, a theory proposed by his Harvard mentor Irving Babbitt (1865-1933). This study reveals how Byron was appropriated to serve conflicting poetic and ideological purposes in early republican China and suggests that imitation as a type of rewriting merits further attention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=George%20Gordon%20Byron" title="George Gordon Byron">George Gordon Byron</a>, <a href="https://publications.waset.org/abstracts/search?q=ideology" title=" ideology"> ideology</a>, <a href="https://publications.waset.org/abstracts/search?q=imitation" title=" imitation"> imitation</a>, <a href="https://publications.waset.org/abstracts/search?q=poetics" title=" poetics"> poetics</a>, <a href="https://publications.waset.org/abstracts/search?q=translation" title=" translation"> translation</a> </p> <a href="https://publications.waset.org/abstracts/102749/ideological-and-poetological-tensions-wu-mis-enterprise-of-imitating-and-translating-george-gordon-byron" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102749.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">230</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">20</span> A Comprehensive CFD Model for Sugar-Cane Bagasse Heterogeneous Combustion in a Grate Boiler System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Jos%C3%A9%20de%20Oliveira%20Ferreira">Daniel José de Oliveira Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Harold%20Sosa-Arnao"> Juan Harold Sosa-Arnao</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20C%C3%A1ssio%20Moreira"> Bruno Cássio Moreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Paes%20Rangel"> Leonardo Paes Rangel</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Won%20Park"> Song Won Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The comprehensive CFD models have been used to represent and study the heterogeneous combustion of biomass. In the present work, the operation of a global flue gas circuit in the sugar-cane bagasse combustion, from wind boxes below primary air grate supply, passing by bagasse insertion in swirl burners and boiler furnace, to boiler bank outlet is simulated. It uses five different meshes representing each part of this system located in sequence: wind boxes and grate, boiler furnace, swirl burners, super heaters and boiler bank. The model considers turbulence using standard k-ε, combustion using EDM, radiation heat transfer using DTM with 16 ray directions and bagasse particle tracking represented by Schiller-Naumann model. The results showed good agreement with expected behavior found in literature and equipment design. The more detailed results view in separated parts of flue gas system allows to observe some flow behaviors that cannot be represented by usual simplifications like bagasse supply under homogeneous axial and rotational vectors and others that can be represented using new considerations like the representation of 26 thousand grate orifices by 144 rectangular inlets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comprehensive%20CFD%20model" title="comprehensive CFD model">comprehensive CFD model</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar-cane%20bagasse%20combustion" title=" sugar-cane bagasse combustion"> sugar-cane bagasse combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar-cane%20bagasse%20grate%20boiler" title=" sugar-cane bagasse grate boiler"> sugar-cane bagasse grate boiler</a>, <a href="https://publications.waset.org/abstracts/search?q=axial" title=" axial"> axial</a> </p> <a href="https://publications.waset.org/abstracts/22864/a-comprehensive-cfd-model-for-sugar-cane-bagasse-heterogeneous-combustion-in-a-grate-boiler-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22864.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">472</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">19</span> A Phenomenological Method Based on Professional Descriptions of Community-of-Practice Members to Scientifically Determine the Level of Child Psycho-Social-Emotional Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gianni%20Jacucci">Gianni Jacucci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alfred Schutz (1932), at the very turning towards phenomenology, of the attention for the social sciences, stated that successful communication of meanings requires the sharing of “sedimenta-tions “ of previous meanings. Börje Langefors (1966), at the very beginning of the social studies of information systems, stated that a common professional basis is required for a correct sharing of meanings, e. g., “standardised accounting data among accountants”. Harold Garfinkel (1967), at the very beginning of ethnomethodology, stated that the accounting of social events must be carried out in the same language used by the actors of those events in managing their practice. Community of practice: we advocate professional descriptions of the community of practice members to scientifically determine the level of child psycho social emotional development. Our approach consists of an application to Human Sciences of Husserl’s Phenomenological Philosophy using a method reminder of Giorgi’s DPM in Psychology. Husserl’s requirement of "Epoché," which involves eliminating prejudices from the minds of observers, is met through "concept cleaning," achieved by consistently sharing disciplinary concepts within their community of practice. Mean-while, the absence of subjective bias is ensured by the meticulous attention to detail in their professional expertise. Our approach shows promise in accurately assessing many other properties through detailed professional descriptions of the community of practice members. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scientific%20rigour" title="scientific rigour">scientific rigour</a>, <a href="https://publications.waset.org/abstracts/search?q=descriptive%20phenomenological%20method" title=" descriptive phenomenological method"> descriptive phenomenological method</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentation%20of%20meanings" title=" sedimentation of meanings"> sedimentation of meanings</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20of%20practice" title=" community of practice"> community of practice</a> </p> <a href="https://publications.waset.org/abstracts/185800/a-phenomenological-method-based-on-professional-descriptions-of-community-of-practice-members-to-scientifically-determine-the-level-of-child-psycho-social-emotional-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185800.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">57</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">18</span> Contextualizing Communication through Culture and Social Structure: An Exploration of Media Life</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyoti%20Ranjan%20Sahoo">Jyoti Ranjan Sahoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Communication is a social phenomenon which mediates to our everyday life and it creates, maintains, builds, circulates, and propagates for a common identity the society. The symbolic forms of communication such as aural, sounds, oral expressions, signs, and language as means of communication are being used in everyday life in helping to identify as construction of social reality. These symbolic forms of communication are treated as the social process in everyday life. Therefore, there is an intrinsic relationship between communication and culture to understand media life for village communities. Similarly, the interface of communication with social life is reflected upon it’s formulation of the notions of social structure and culture. It has been observed that there is an overlapping and new phenomenonal change of media life among marginalized communities in general and village communities in particular. Therefore, this paper is an outcome of decadal stock of literature and an empirical investigation on understanding of communication in a tribal village in India. It has examined the idea of American scientist Edward T. Hall “the culture is communication, and the communication is culture” in village society on understanding media life. Thus, the Harold Innis’s theoretical idea of “communication” has been critically examined in these contexts since author tries to explore and understand the inter-disciplinarity on understanding media life through communication and culture which is embedded in socio-cultural life bearing on epistemological and ontological implications. The paper tries to explore and understand the inter-disciplinary and historical trajectories of communication embedded with other social science disciplines; and also tries to map these studies relevant for the future directions and engagement which would have bearing on epistemological and ontological implications in the field of media and communication. <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=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=history" title=" history"> history</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=oral" title=" oral"> oral</a>, <a href="https://publications.waset.org/abstracts/search?q=tradition" title=" tradition"> tradition</a> </p> <a href="https://publications.waset.org/abstracts/42363/contextualizing-communication-through-culture-and-social-structure-an-exploration-of-media-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42363.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">361</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">17</span> 'Infection in the Sentence': The Castration of a Black Woman's Dream of Authorship as Manifested in Buchi Emecheta's Second Class Citizen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aseel%20Hatif%20Jassam">Aseel Hatif Jassam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadeel%20Hatif%20Jassam"> Hadeel Hatif Jassam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper discusses the phallocentric discourse that is challenged by women in general and of women of color in particular in spite of the simultaneity of oppression due to race, class, and gender in the diaspora. Therefore, the paper gives a brief account of women's experience in the light of postcolonial feminist theory. The paper also cast light on the theories of Luce Irigaray and Helen Cixous, two Feminist theorists who support and advise women to have their own discourse to challenge the infectious patriarchal sentence advocated by Sigmund Freud and Harold Bloom's model of literary history. Black women authors like BuchiEmecheta as well as her alter ego Adah, a Nigerian-born girl and the protagonist of her semi-autobiographical novel, Second Class Citizen, suffer from this phallocentric and oppressive sentence and displacement as they migrate from Nigeria, a former British colony where they feel marginalized to North London with the hope of realizing their dreams. Yet, in the British diaspora, they get culturally shocked and continue to suffer from further marginalization due to class and race and are insulted and interiorized ironically by their patriarchal husbands who try to put an end to their dreams of authorship. With the phallocentric belief that women aren't capable of self-representation in the background of their mindsets, the violent Sylvester Onwordi and Francis Obi, the husbands of both Emecheta and Adah, respectively have practiced oppression on them by burning their own authoritative voice, represented by the novels they write while they are struggling with their economically atrocious living experience in the British diaspora. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=authorship" title="authorship">authorship</a>, <a href="https://publications.waset.org/abstracts/search?q=British%20diaspora" title=" British diaspora"> British diaspora</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse" title=" discourse"> discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=phallocentric" title=" phallocentric"> phallocentric</a>, <a href="https://publications.waset.org/abstracts/search?q=patriarchy" title=" patriarchy"> patriarchy</a> </p> <a href="https://publications.waset.org/abstracts/143968/infection-in-the-sentence-the-castration-of-a-black-womans-dream-of-authorship-as-manifested-in-buchi-emechetas-second-class-citizen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143968.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">177</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">16</span> Network Conditioning and Transfer Learning for Peripheral Nerve Segmentation in Ultrasound Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20Mauricio%20D%C3%ADaz-Vargas">Harold Mauricio Díaz-Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Alfonso%20Jimenez-Casta%C3%B1o"> Cristian Alfonso Jimenez-Castaño</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Augusto%20C%C3%A1rdenas-Pe%C3%B1a"> David Augusto Cárdenas-Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillermo%20Alberto%20Ortiz-G%C3%B3mez"> Guillermo Alberto Ortiz-Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alvaro%20Angel%20Orozco-Gutierrez"> Alvaro Angel Orozco-Gutierrez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Precise identification of the nerves is a crucial task performed by anesthesiologists for an effective Peripheral Nerve Blocking (PNB). Now, anesthesiologists use ultrasound imaging equipment to guide the PNB and detect nervous structures. However, visual identification of the nerves from ultrasound images is difficult, even for trained specialists, due to artifacts and low contrast. The recent advances in deep learning make neural networks a potential tool for accurate nerve segmentation systems, so addressing the above issues from raw data. The most widely spread U-Net network yields pixel-by-pixel segmentation by encoding the input image and decoding the attained feature vector into a semantic image. This work proposes a conditioning approach and encoder pre-training to enhance the nerve segmentation of traditional U-Nets. Conditioning is achieved by the one-hot encoding of the kind of target nerve a the network input, while the pre-training considers five well-known deep networks for image classification. The proposed approach is tested in a collection of 619 US images, where the best C-UNet architecture yields an 81% Dice coefficient, outperforming the 74% of the best traditional U-Net. Results prove that pre-trained models with the conditional approach outperform their equivalent baseline by supporting learning new features and enriching the discriminant capability of the tested networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nerve%20segmentation" title="nerve segmentation">nerve segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=U-Net" title=" U-Net"> U-Net</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound%20imaging" title=" ultrasound imaging"> ultrasound imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=peripheral%20nerve%20blocking" title=" peripheral nerve blocking"> peripheral nerve blocking</a> </p> <a href="https://publications.waset.org/abstracts/152338/network-conditioning-and-transfer-learning-for-peripheral-nerve-segmentation-in-ultrasound-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152338.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Political Regimes, Political Stability and Debt Dependence in African Countries of Franc Zone: A Logistic Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nounamo%20Nguedie%20Yann%20Harold">Nounamo Nguedie Yann Harold</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The factors behind the debt have been the subject of several studies in the literature. Pioneering studies based on the 'double deficit' approach linked indebtedness to the imbalance between savings and investment, the budget deficit and the current account deficit. Most studies on identifying factors that may stimulate or reduce the level of external public debt agree that the following variables are important explanatory variables in leveraging debt: the budget deficit, trade opening, current account and exchange rate, import, export, interest rate, term variation exchange rate, economic growth rate and debt service, capital flight, and over-indebtedness. Few studies addressed the impact of political factors on the level of external debt. In general, however, the IMF's stabilization programs in developing countries following the debt crisis have resulted in economic recession and the advent of political crises that have resulted in changes in governments. In this sense, political institutions are recognised as factors of accumulation of external debt in most developing countries. This paper assesses the role of political factors on the external debt level of African countries in the Franc Zone over the period 1985-2016. Data used come from World Bank and ICRG. Using a logit in panel, the results show that the more a country is politically stable, the lower the external debt compared to the gross domestic product. Political stability multiplies 1.18% the chances of being in the sustainable debt zone. For example, countries with good political institutions experience less severe external debt burdens than countries with bad political institutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20countries" title="African countries">African countries</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20debt" title=" external debt"> external debt</a>, <a href="https://publications.waset.org/abstracts/search?q=Franc%20Zone" title=" Franc Zone"> Franc Zone</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20factors" title=" political factors"> political factors</a> </p> <a href="https://publications.waset.org/abstracts/86865/political-regimes-political-stability-and-debt-dependence-in-african-countries-of-franc-zone-a-logistic-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86865.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">219</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">14</span> Groundhog Day as a Model for the Repeating Spectator and the Film Academic: Re-Watching the Same Films Again Can Create Different Experiences and Ideas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leiya%20Ho%20Yin%20Lee">Leiya Ho Yin Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundhog Day (Harold Ramis, 1993) may seemingly be a fairly unremarkable Hollywood comedy film in the 90s, it is argued that the film, with its protagonist Phil (Bill Murray), inadvertently, but perfectly, demonstrates an important aspect in filmmaking, film spectatorship and film research: repetition. Very rarely does a narrative film use one, and only one, take in its shooting. The multiple ‘repeats’ of Phil’s various endeavours due to his being trapped in a perpetual loop of the same day — from stealing money and tricking a woman into a casual relationship, to his multiple suicides, to eventually helping people in need — make the process of doing multiple ‘takes’ in filmmaking explicit. But perhaps more significantly, Phil represents a perfect model for the spectator/cinephile who has seen their favourite film for multiple times that they can remember every single detail. Crucially, their favourite film never changes, as it is a recording, but the cinephile’s experience of that very same film is most likely different each time they watch it again, just as Phil’s character and personality has completely transformed, from selfish and egotistic, to depressed and nihilistic, and ultimately to sympathetic and caring, even though he is living the exact same day. Furthermore, the author did not come up with this stimulating juxtaposition of film spectatorship and Groundhog Day the first time the author saw the film; it took the author a few casual re-viewings to notice the film’s self-reflexivity. And then, when working on it in the author’s research, the author had to re-view the film for more times, and have subsequently noticed even more things previously unnoticed. In this way, Groundhog Day not only stands for a model for filmmaking and film spectatorship, it also illustrates the act of academic research, especially in Film Studies where repeatedly viewing the same films is a prerequisite before new ideas and concepts are discovered from old material. This also recalls Deleuze’s thesis on difference and repetition in that repetition creates difference and it is difference that creates thought. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=narrative%20comprehension" title="narrative comprehension">narrative comprehension</a>, <a href="https://publications.waset.org/abstracts/search?q=repeated%20viewing" title=" repeated viewing"> repeated viewing</a>, <a href="https://publications.waset.org/abstracts/search?q=repetition" title=" repetition"> repetition</a>, <a href="https://publications.waset.org/abstracts/search?q=spectatorship" title=" spectatorship"> spectatorship</a> </p> <a href="https://publications.waset.org/abstracts/61535/groundhog-day-as-a-model-for-the-repeating-spectator-and-the-film-academic-re-watching-the-same-films-again-can-create-different-experiences-and-ideas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61535.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">320</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">13</span> The Minimum Age of Criminal Responsibility in the Philippines: Balancing International Standards and Domestic Concerns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20P.%20Pareja">Harold P. Pareja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper answers the question whether the minimum age of criminal responsibility under the Republic Act No. 9344 (Juvenile Justice Act) as amended by Republic Act No. 10630 should be lowered to 15 years of age or not in the light of international standards and domestic concerns both of which will definitely elicit strong views. It also explores the specific provision on the minimum age of criminal responsibility under the Republic Act No. 9344 (Juvenile Justice Act) and traces the bases of such law by discussing its presented evidences and justifications as reflected in the records of proceedings in the law-making phase. On one hand, the paper discusses the impact of lowering the minimum age to the state of juvenile delinquencies and to the rate of rehabilitation for those CICL who have undergone the DSWD-supervised recovery programs. On the other hand, it presents its impact to the international community specifically to the Committee of the Rights of the Child and the UNICEF considering that the even the current minimum age set in RA 9344 is lower than the international standards. Document review and content analysis are the major research tools. Primary and secondary sources were used as references such as Philippine laws on juvenile justice and from the different states international think-tanks. The absence of reliable evidences on criminal capacity made the arguments in increasing the MACR in the harder position. Studies on criminal capacity vary from different countries and from practitioners in in the fields of psychology, psychiatry and forensics. Juvenile delinquency is mainly contributed by poverty and dysfunctional families. On the other hand, the science of the criminal mind specifically among children has not been established yet. Philippines have the legal obligations to be faithful to the CRC and other related international instruments for the juvenile justice and welfare system. Decreasing MACR does not only send wrong message to the international community but the Philippines is violating its own laws. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=juvenile%20justice" title="juvenile justice">juvenile justice</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20age%20of%20responsibility%20%28MAR%29" title=" minimum age of responsibility (MAR)"> minimum age of responsibility (MAR)</a>, <a href="https://publications.waset.org/abstracts/search?q=juvenile%20justice%20act%20of%20the%20Philippines" title=" juvenile justice act of the Philippines"> juvenile justice act of the Philippines</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20in%20conflict%20with%20the%20law" title=" children in conflict with the law"> children in conflict with the law</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20standards%20on%20juvenile%20justice" title=" international standards on juvenile justice"> international standards on juvenile justice</a> </p> <a href="https://publications.waset.org/abstracts/40186/the-minimum-age-of-criminal-responsibility-in-the-philippines-balancing-international-standards-and-domestic-concerns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40186.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">407</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">12</span> Spherical Organic Particle (SOP) Emissions from Fixed-Bed Residential Coal-Burning Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tafadzwa%20Makonese">Tafadzwa Makonese</a>, <a href="https://publications.waset.org/abstracts/search?q=Harold%20Annegarn"> Harold Annegarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Forbes"> Patricia Forbes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Residential coal combustion is one of the largest sources of carbonaceous aerosols in the Highveld region of South Africa, significantly affecting the local and regional climate. In this study, we investigated single coal burning particles emitted when using different fire-ignition techniques (top-lit up-draft vs bottom-lit up-draft) and air ventilation rates (defined by the number of air holes above and below the fire grate) in selected informal braziers. Aerosol samples were collected on nucleopore filters at the SeTAR Centre Laboratory, University of Johannesburg. Individual particles (~700) were investigated using a scanning electron microscope equipped with an energy-dispersive X-ray spectroscopy (EDS). Two distinct forms of spherical organic particles (SOPs) were identified, one less oxidized than the other. The particles were further classified into "electronically" dark and bright, according to China et al. [2014]. EDS analysis showed that 70% of the dark spherical organic particles balls had higher (~60%) relative oxygen content than in the bright SOPs. We quantify the morphology of spherical organic particles and classify them into four categories: ~50% are bare single particles; ~35% particles are aggregated and form diffusion accretion chains; 10% have inclusions; and 5% are deformed due to impaction on filter material during sampling. We conclude that there are two distinct kinds of coal burning spherical organic particles and that dark SOPs are less volatile than bright SOPs. We also show that these spherical organic particles are similar in nature and characteristics to tar balls observed in biomass combustion, and that they have the potential to absorb sunlight thereby affecting the earth’s radiative budget and climate. This study provides insights on the mixing states, morphology, and possible formation mechanisms of these organic particles from residential coal combustion in informal stoves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spherical%20organic%20particles" title="spherical organic particles">spherical organic particles</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20coal%20combustion" title=" residential coal combustion"> residential coal combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed-bed" title=" fixed-bed"> fixed-bed</a>, <a href="https://publications.waset.org/abstracts/search?q=aerosols" title=" aerosols"> aerosols</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=stoves" title=" stoves"> stoves</a> </p> <a href="https://publications.waset.org/abstracts/22636/spherical-organic-particle-sop-emissions-from-fixed-bed-residential-coal-burning-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22636.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">466</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">11</span> Investigation of Scaling Laws for Stiffness and strength in Bioinspired Glass Sponge Structures Produced by Fused Filament Fabrication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Beigi%20Rizi">Hassan Beigi Rizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Harold%20Auradou"> Harold Auradou</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamine%20Hattali"> Lamine Hattali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various industries, including civil engineering, automotive, aerospace, and biomedical fields, are currently seeking novel and innovative high-performance lightweight materials to reduce energy consumption. Inspired by the structure of Euplectella Aspergillum Glass Sponges (EA-sponge), 2D unit cells were created and fabricated using a Fused Filament Fabrication (FFF) process with Polylactic acid (PLA) filaments. The stiffness and strength of bio-inspired EA-sponge lattices were investigated both experimentally and numerically under uniaxial tensile loading and are compared to three standard square lattices with diagonal struts (Designs B and C) and non-diagonal struts (Design D) reinforcements. The aim is to establish predictive scaling laws models and examine the deformation mechanisms involved. The results indicated that for the EA-sponge structure, the relative moduli and yield strength scaled linearly with relative density, suggesting that the deformation mechanism is stretching-dominated. The Finite element analysis (FEA), with periodic boundary conditions for volumetric homogenization, confirms these trends and goes beyond the experimental limits imposed by the FFF printing process. Therefore, the stretching-dominated behavior, investigated from 0.1 to 0.5 relative density, demonstrate that the study of EA-sponge structure can be exploited for the realization of square lattice topologies that are stiff and strong and have attractive potential for lightweight structural applications. However, the FFF process introduces an accuracy limitation, with approximately 10% error, making it challenging to print structures with a relative density below 0.2. Future work could focus on exploring the impact of different printing materials on the performance of EA-sponge structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-inspiration" title="bio-inspiration">bio-inspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=lattice%20structures" title=" lattice structures"> lattice structures</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20filament%20fabrication" title=" fused filament fabrication"> fused filament fabrication</a>, <a href="https://publications.waset.org/abstracts/search?q=scaling%20laws" title=" scaling laws"> scaling laws</a> </p> <a href="https://publications.waset.org/abstracts/194587/investigation-of-scaling-laws-for-stiffness-and-strength-in-bioinspired-glass-sponge-structures-produced-by-fused-filament-fabrication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194587.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">6</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">10</span> Outcome at the Extreme of Viability: A Single-Centre Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonia%20Harold-Barry">Antonia Harold-Barry</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Dempsey"> Eugene Dempsey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The objective is to examine the survival and outcome of infants born under 26 weeks gestation in an Irish tertiary maternity hospital from 2007-2016 and to describe the survival and neurodevelopmental outcomes of these extremely preterm infants. Method: The population is 132 infants born at 23, 24, and 25 weeks in Cork University Maternity Hospital from 2007 to 2016. Ethical approval was granted by the Cork Clinical Research Ethics Committee. Patient details were obtained from the Vermont Oxford and Badger Networks. Survival rates and Bayley scores were calculated to assess neurodevelopmental outcomes. Statistical analysis with SPSS included frequencies, distributions, and comparisons between data from 2007-2011 and 2012-2016. Results: Overall survival rate was 63%. Of the surviving babies, 61% had Bayley scores calculated. Survival stood at 39% for delivery at 23 weeks, 50% at 24 weeks, and 83% at 25 weeks. The 2012 to 2016 cohort has shown further increases in survival, with 50% of babies at 23 weeks, 58% at 24 weeks, and 89% at 25 weeks. Corresponding figures for 2007-2011 are 20%, 39%, and 75%. Gestational age and incidence of periventricular leukomalacia were statistically significant, with a p-value of 0.022. Gestational age and delivery room deaths had a p-value of 0.025, as did gestational age and birth weight. A comparison of the two cohorts (2007-2011 and 2012-2016) with the administration of antenatal steroids showed a statistically significant p-value of 0.044. Conclusion: There is less morbidity and mortality in infants born at 25 than at 23 or 24 weeks. Survival of extremely premature infants has increased significantly over the past ten years. Survival rates with normal neurodevelopmental outcomes are comparable with international standards and reflect positive changes in attitude and practices in neonatal intensive care. This study will inform parents about the potential outcomes of extreme prematurity and policy regarding the management of extreme prematurity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extreme%20of%20viability" title="extreme of viability">extreme of viability</a>, <a href="https://publications.waset.org/abstracts/search?q=neurodevelopmental%20outcome" title=" neurodevelopmental outcome"> neurodevelopmental outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=periventricular%20leukomalacia" title=" periventricular leukomalacia"> periventricular leukomalacia</a>, <a href="https://publications.waset.org/abstracts/search?q=prematurity" title=" prematurity"> prematurity</a> </p> <a href="https://publications.waset.org/abstracts/164080/outcome-at-the-extreme-of-viability-a-single-centre-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164080.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">89</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">9</span> Arsenic and Fluoride Contamination in Lahore, Pakistan: Spatial Distribution, Mineralization Control and Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Abbas%20Soharwardi">Zainab Abbas Soharwardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunli%20Su"> Chunli Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Harold%20Wilson%20Tumwitike%20Mapoma"> Harold Wilson Tumwitike Mapoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Zahid%20Aziz"> Syed Zahid Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmut%20Ince"> Mahmut Ince</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the spatial variations of groundwater chemistry used by communities in Lahore city with emphasis on arsenic (As) and fluoride (F) levels. A total of 472 tubewell samples were collected from 7 towns and analyzed for physical and chemical parameters, including pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), total hardness, HCO3, Ca2+, Mg2+, Na+, K+, SO42-, Cl-, NO3-, NO2-, F- and As. There were significant spatial variations observed for total hardness, TDS, HCO3, NO3 and As. In general, the south-east of the city displayed higher TH and HCO3 while the north-east showed significantly higher As concentrations attributed to the heterogeneity of the aquifer and industrial activities. In most cases, As was higher than WHO limit value. Indiscriminate disposal of domestic and commercial wastewater into River Ravi is the cause of elevated NO3 observed in the north-west compared to other places in the area. Investigation of the groundwater type revealed facies in the order: Ca-Mg-HCO3-SO4 > Mg-Ca-HCO3-SO4 > Ca-Mg-HCO3-SO4-Cl > Mg-Ca-HCO3-SO4 > Ca-HCO3-SO4 > Ca-Mg-SO4-HCO3. The plausible mineralization control mechanism seems to be that of carbonate weathering, although silicate weathering is probable. Moreover, PHREEQC model results showed that the groundwater was under saturated with respect to evaporites (anhydrite, fluorite, gypsum and halite) while generally equilibrium to saturated with respect to aragonite, calcite and dolomite. The Hierarchical Cluster Analysis (HCA) showed that pH significantly affected As, F, NO3 and NO2 while HCO3 contributing most to the observed TDS values in Lahore. It is concluded that inherent mineral dissolution/ precipitation, pH, oxic conditions, anthropogenic activities, atmospheric transport/ wet deposition, microbial activities and surface soil characteristics play their significant roles in elevating both As and F in the city's groundwater. <p class="card-text"><strong>Keywords:</strong> <a
