There is need for quantitative information on its benefits and contributions to rural household. The main objective of this study is to investigate contributions of home garden to income of rural households in Raymond Mhlaba Local Municipality, formerly Nkonkobe Local Municipality of Eastern Cape Province South Africa. The stratified random sampling method was applied in order to choose a sample of 160 households.The study was conducted among 80 households engaging in home gardens and 80 non- participating households in the study area. Data analysis employed descriptive statistics with the use of frequency table and one way sample T test to show actual contributions. The overall model shows that social grant has the highest contribution to total household income for both categories while income generated from home garden has the second largest share to total household income, this shows that the majority of rural households in the study area rely on social grant as their source of income. However, since most households are net food buyers, it is essential to have policies that are formulated with an understanding that household food security is not only a function of the food that farming households produce for their own consumption but more so a function of total household income. The results produced sufficient evidence that home gardens contribute significantly to income of rural household. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20security" title="food security">food security</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20gardening" title=" home gardening"> home gardening</a>, <a href="https://publications.waset.org/abstracts/search?q=household" title=" household"> household</a>, <a href="https://publications.waset.org/abstracts/search?q=income" title=" income"> income</a> </p> <a href="https://publications.waset.org/abstracts/95570/contribution-of-home-gardens-to-rural-household-income-in-raymond-mhlaba-local-municipality-eastern-cape-province-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95570.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">225</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">53</span> Primary Cryptococcal Pneumonia in an HIV Positive Filipino Patient</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Andrew%20Tu">Mark Andrew Tu</a>, <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Olazo"> Raymond Olazo</a>, <a href="https://publications.waset.org/abstracts/search?q=Cybele%20Abad"> Cybele Abad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cryptococcosis is an invasive infection most commonly found in patients who are immuno compromised.

However, many students do not have a clear understanding of what learning is, what they are learning, and why they are learning. Many students study simply to pass rather than to learn something useful for their career and their life. They have a misconception about learning and a wrong attitude towards learning. This research explores student attitudes to study in management education and explores how to intercede to lead students from shallow to deeper modes of learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge" title="knowledge">knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20learning" title=" surface learning"> surface learning</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=education" title=" education"> education</a> </p> <a href="https://publications.waset.org/abstracts/143479/how-to-guide-students-from-surface-to-deep-learning-applied-philosophy-in-management-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143479.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">501</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">51</span> Structural and Functional Comparison of Untagged and Tagged EmrE Protein</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Junaid%20S.%20Qazi">S.

Turner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> EmrE, a member of the small multidrug resistance protein family in bacteria is considered to be the archetypical member of its family. It confers host resistance to a wide variety of quaternary cation compounds (QCCs) driven by proton motive force. Generally, purification yield is a challenge in all membrane proteins because of the difficulties in their expression, isolation and solubilization. EmrE is extremely hydrophobic which make the purification yield challenging. We have purified EmrE protein using two different approaches: organic solvent membrane extraction and hexahistidine (his6) tagged Ni-affinity chromatographic methods. We have characterized changes present between ligand affinity of untagged and his6-tagged EmrE proteins in similar membrane mimetic environments using biophysical experimental techniques. Purified proteins were solubilized in a buffer containing n-dodecyl-β-D-maltopyranoside (DDM) and the conformations in the proteins were explored in the presence of four QCCs, methyl viologen (MV), ethidium bromide (EB), cetylpyridinium chloride (CTP) and tetraphenyl phosphonium (TPP). SDS-Tricine PAGE and dynamic light scattering (DLS) analysis revealed that the addition of QCCs did not induce higher multimeric forms of either proteins at all QCC:EmrE molar ratios examined under the solubilization conditions applied. QCC binding curves obtained from the Trp fluorescence quenching spectra, gave the values of dissociation constant (Kd) and maximum specific one-site binding (Bmax). Lower Bmax values to QCCs for his6-tagged EmrE shows that the binding sites remained unoccupied. This lower saturation suggests that the his6-tagged versions provide a conformation that prevents saturated binding. Our data demonstrate that tagging an integral membrane protein can significantly influence the protein. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20multidrug%20resistance%20%28SMR%29%20protein" title="small multidrug resistance (SMR) protein">small multidrug resistance (SMR) protein</a>, <a href="https://publications.waset.org/abstracts/search?q=EmrE" title=" EmrE"> EmrE</a>, <a href="https://publications.waset.org/abstracts/search?q=integral%20membrane%20protein%20folding" title=" integral membrane protein folding"> integral membrane protein folding</a>, <a href="https://publications.waset.org/abstracts/search?q=quaternary%20ammonium%20compounds%20%28QAC%29" title=" quaternary ammonium compounds (QAC)"> quaternary ammonium compounds (QAC)</a>, <a href="https://publications.waset.org/abstracts/search?q=quaternary%20cation%20compounds%20%28QCC%29" title=" quaternary cation compounds (QCC)"> quaternary cation compounds (QCC)</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20affinity%20chromatography" title=" nickel affinity chromatography"> nickel affinity chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=hexahistidine%20%28His6%29%20tag" title=" hexahistidine (His6) tag"> hexahistidine (His6) tag</a> </p> <a href="https://publications.waset.org/abstracts/36260/structural-and-functional-comparison-of-untagged-and-tagged-emre-protein" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36260.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">379</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">50</span> Relationship between Food Inflation and Agriculture Lending Rate in Ghana: A Vector Autoregressive Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20K.%20Dziwornu">Raymond K.

This study examined how food inflation and agriculture lending rate react to each other in Ghana using vector autoregressive approach. Quarterly data from 2006 to 2018 was obtained from the Bank of Ghana quarterly bulletin and the Ghana Statistical Service reports. The study found that a positive standard deviation shock to food inflation causes lending rate of agriculture loan to react negatively in the short run, but positively and steadily in the long run. This suggests the need to direct appropriate policy measures to reduce food inflation and consequently, the cost of credit to the agricultural sector for its growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20inflation" title="food inflation">food inflation</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=lending%20rate" title=" lending rate"> lending rate</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20autoregressive" title=" vector autoregressive"> vector autoregressive</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a> </p> <a href="https://publications.waset.org/abstracts/115221/relationship-between-food-inflation-and-agriculture-lending-rate-in-ghana-a-vector-autoregressive-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115221.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">150</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">49</span> A Product-Specific/Unobservable Approach to Segmentation for a Value Expressive Credit Card Service</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manfred%20F.%20Maute">Manfred F.

The variety of segments elicited by agglomerative and k means clustering and the familiar profiles of individual clusters suggest that the face validity of the psychographic segmentation was quite high. Segmentation had a significant effect on customer satisfaction and relationship depth. However, when socio-demographic characteristics like household size and income were accounted for in the psychographic segmentation, the effect on relational response differences was magnified threefold.

A comparison between the measured data and predictive data of permanent deformation predictive models showed the limits of existing prediction models. The numerical analysis described the permanent deformation zones and concluded that angularity has an effect of the onset of these zones.

Plants in their natural state are mostly colonized by endophytes which in the process forms symbiotic associations with the host plants. These benefits that the endophytes offer to the plants include amongst others to: Enhance plants growth through the production of various phytohormones; increase in the resistance of environmental stresses; produce important bioactive metabolites; help in the fixing of nitrogen in the plants organelles; help in the metal translocation and accumulation in plants; assist in the production of enzymes involves the degradation of organic contaminants. Therefore recognizing these natural processes of the microbes will enable the understanding of the effective mechanism for enhanced phytoremediation. The aim of this study was to survey the progressiveness in the study involving endophyte-assisted phytoremediation of contaminants; highlighting various pollutants, the plants used, the endophytes studied as well as the type of interaction between the plants and the microbes so as to proffer a better future prospect for the technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title="phytoremediation">phytoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=endophytes" title=" endophytes"> endophytes</a>, <a href="https://publications.waset.org/abstracts/search?q=microbes" title=" microbes"> microbes</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20management" title=" environmental management"> environmental management</a>, <a href="https://publications.waset.org/abstracts/search?q=plants" title=" plants"> plants</a> </p> <a href="https://publications.waset.org/abstracts/29046/enhanced-phytoremediation-using-endophytic-microbes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29046.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">346</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">46</span> Systems Contextual Integrated Model for Clinical Psychology and Social Work</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20C.%20Hawkins%20II">Raymond C.

The SCIM “healing cycle” is an allostatic hedonic affective-cognitive right-hemisphere–left-hemisphere coordinated process involving positive alliesthesia that mitigates traumatic pain and generates psychological flexibility. The SCIM “trauma cycle” is an allostatic overload alliesthesia opponent process with long-lasting pathology sequelae. The social ecological context moderates the “healing cycle” and the “trauma cycle.” Repeated evocation of the “healing cycle” in a therapeutic relationship can gradually relieve trauma sequelae. The SCIM is applied to pain, obese binge eating, and substance use disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allostasis" title="allostasis">allostasis</a>, <a href="https://publications.waset.org/abstracts/search?q=alliesthesia" title=" alliesthesia"> alliesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=opponent%20process" title=" opponent process"> opponent process</a>, <a href="https://publications.waset.org/abstracts/search?q=behavioral%20health" title=" behavioral health"> behavioral health</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a> </p> <a href="https://publications.waset.org/abstracts/137308/systems-contextual-integrated-model-for-clinical-psychology-and-social-work" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137308.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">142</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">45</span> Fabrication of Profile-Coated Rhodium X-Ray Focusing Mirror</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bing%20Shi">Bing Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Raymond%20A.%20Conley"> Raymond A.

This is the first pair of Rhodium-coated KB mirrors with elliptical shape that was fabricated using the profile coating technique. The profile coating technique is to coat the substrate with designed shape using masks during the deposition. The mirrors were equipped at the beamline and achieved the designed focusing requirement.

From experimental results, Venonia amydalina (bitter leaf) contained 150 mg (0.15 g) of sodium and 20500 mg (20.5 g) potassium with a ratio of 0.007, Brassica oleracea var capitata (cabbage) contained 300 mg (0.3 g) of sodium and 19000 mg (19 g) of potassium with a ration of 0.012. Others are Telfairia occidentalis (fluted pumpkin) with 400 mg (0.45 g) of sodium and 19500 mg (19.5 g) of potassium with a ratio of 0.020; Hibiscus sabdriffa (sorrel) has 200 mg (0.2 g) of sodium and 600 mg (0.6 g) of potassium with a ratio of 0.300; and Amarantus caudatus (spinach) contained 450 mg (0.45 g) of sodium and 23000 mg (23 g) of potassium with a ratio of 0.020. The presence of sodium and potassium in foods has become increasingly important as recent studies and dietary information gathered in this research has shown that sodium intake is not the sole consideration in elevated blood pressure but its considered as a ratio Na+/K+ fixed at 0.6. This ratio has been found to be a more important factor, suggesting that our diet should contain 67 % more potassium than sodium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vegetables" title="vegetables">vegetables</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium" title=" sodium"> sodium</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium" title=" potassium"> potassium</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20pressure" title=" blood pressure"> blood pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=diet" title=" diet"> diet</a>, <a href="https://publications.waset.org/abstracts/search?q=foods" title=" foods "> foods </a> </p> <a href="https://publications.waset.org/abstracts/11091/the-determination-of-sodiumpotassium-ion-ratio-in-selected-edible-leafy-vegetables-in-north-eastern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11091.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">478</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">43</span> Standardization Of Miniature Neutron Research Reactor And Occupational Safety Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Limen%20Njinga">Raymond Limen Njinga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The comparator factors (Fc) for miniature research reactors are of great importance in the field of nuclear physics as it provide accurate bases for the evaluation of elements in all form of samples via ko-NAA techniques. The Fc was initially simulated theoretically thereafter, series of experiments were performed to validate the results. In this situation, the experimental values were obtained using the alloy of Au(0.1%) - Al monitor foil and a neutron flux setting of 5.00E+11 cm-2.s-1. As was observed in the inner irradiation position, the average experimental value of 7.120E+05 was reported against the theoretical value of 7.330E+05. In comparison, a percentage deviation of 2.86 (from theoretical value) was observed. In the large case of the outer irradiation position, the experimental value of 1.170E+06 was recorded against the theoretical value of 1.210E+06 with a percentage deviation of 3.310 (from the theoretical value).

This paper describes part of a recently completed experimental research program to assess the effects of different structural parameters on the development length requirements of modern high strength steel reinforcing bars, including the case of lapped splices in large-scale reinforced concrete members. The normalized average bond stresses for the different variations of anchorage lengths are assessed according to the general form of a typical empirical analytical model of bond and anchorage.

As a gluten-free (GF) diet has become a concern of many people for health reasons, a gold standard had to be nominated. Enzyme-linked immunosorbent assay (ELISA) has taken the seat of this role. However, multiple limitations were discovered, and with that, the desire for an alternative method now exists. Nucleic acid-based aptamers have become of great interest due to their selectivity, specificity, simplicity, and rapid-testing advantages. However, fluorescence-based aptasensors have been tagged as unstable, but lifespan details are rarely stated. In this work, the lifespan stability of a fluorescence-based aptasensor is shown over an 8-week-long study displaying the accuracy of the sensor and false negatives. This study follows 22 different samples, including GF and gluten-rich (GR) and soy sauce products, off-the-shelf products, and reference material from laboratories, giving a total of 836 tests. The analysis shows an accuracy of correctly classifying GF and GR products of 96.30% and 100%, respectively when the protocol is augmented with molecular sieves. The overall accuracy remains around 94% within the first four weeks and then decays to 63%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aptasensor" title="aptasensor">aptasensor</a>, <a href="https://publications.waset.org/abstracts/search?q=PEG" title=" PEG"> PEG</a>, <a href="https://publications.waset.org/abstracts/search?q=rGO" title=" rGO"> rGO</a>, <a href="https://publications.waset.org/abstracts/search?q=FAM" title=" FAM"> FAM</a>, <a href="https://publications.waset.org/abstracts/search?q=RM" title=" RM"> RM</a>, <a href="https://publications.waset.org/abstracts/search?q=ELISA" title=" ELISA"> ELISA</a> </p> <a href="https://publications.waset.org/abstracts/152324/fluorometric-aptasensor-evaluation-of-stability-and-comparison-to-standard-enzyme-linked-immunosorbent-assay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152324.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Supergrid Modeling and Operation and Control of Multi Terminal DC Grids for the Deployment of a Meshed HVDC Grid in South Asia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Beg">Farhan Beg</a>, <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Moberly"> Raymond Moberly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Indian subcontinent is facing a massive challenge with regards to energy security in member countries, to provide reliable electricity to facilitate development across various sectors of the economy and consequently achieve the developmental targets. The instability of the current precarious situation is observable in the frequent system failures and blackouts. The deployment of interconnected electricity ‘Supergrid’ designed to carry huge quanta of power across the Indian sub-continent is proposed in this paper. Besides enabling energy security in the subcontinent, it will also provide a platform for Renewable Energy Sources (RES) integration. This paper assesses the need and conditions for a Supergrid deployment and consequently proposes a meshed topology based on Voltage Source High Voltage Direct Current (VSC-HVDC) converters for the Supergrid modeling. Various control schemes for the control of voltage and power are utilized for the regulation of the network parameters.

The adsorption was characterized using standard methods and values obtained were; pH = 7.80, bulk density = 0.43 g/mL, ash content = 2.2 %, moisture content = 8.27 %, attrition = 1%, and iodine number = 552 mg/g. Adsorption capacity was found to vary with initial concentration, adsorbent dosage, pH, contact time and temperature, the maximum adsorption capacity in each case was found to be at; 30 mg/L for concentration, 0.8 g for adsorbent dose, 5 for pH, 60 minutes for time and 30 °C for temperature. FTIR analysis was done to analyses the surface functional groups which shows the presence of O-H stretch, at 3743.92 corresponding to alcohol, phenols, C-H stretch at 2923.27 indicative of alkanes, H-C=O: C-H stretch at 2725.76 corresponding to aldehyde, C-C stretch at 1462.72 corresponding to aromatic, SEM analysis carried out revealed a rough and smooth morphology of the uncontacted and contacted adsorbent respectively. The experimental data judging from the R2 values fitted best into the Temkin isotherm. The fitting of tetracycline adsorption into the pseudo second order kinetic model (R2 of 0.9992) is suggestive of chemisorption for the adsorbent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorbent%20isotherm" title=" adsorbent isotherm"> adsorbent isotherm</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=tertracycline" title=" tertracycline"> tertracycline</a> </p> <a href="https://publications.waset.org/abstracts/77796/kinetics-and-adsorption-studies-of-tetracycline-from-aqueous-solution-using-melon-husk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77796.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">264</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">36</span> Adaptive Swarm Balancing Algorithms for Rare-Event Prediction in Imbalanced Healthcare Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinyan%20Li">Jinyan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Fong"> Simon Fong</a>, <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Wong"> Raymond Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sabah"> Mohammed Sabah</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiaidhi%20Jinan"> Fiaidhi Jinan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Clinical data analysis and forecasting have make great contributions to disease control, prevention and detection. However, such data usually suffer from highly unbalanced samples in class distributions. In this paper, we target at the binary imbalanced dataset, where the positive samples take up only the minority. We investigate two different meta-heuristic algorithms, particle swarm optimization and bat-inspired algorithm, and combine both of them with the synthetic minority over-sampling technique (SMOTE) for processing the datasets. One approach is to process the full dataset as a whole. The other is to split up the dataset and adaptively process it one segment at a time. The experimental results reveal that while the performance improvements obtained by the former methods are not scalable to larger data scales, the later one, which we call Adaptive Swarm Balancing Algorithms, leads to significant efficiency and effectiveness improvements on large datasets. We also find it more consistent with the practice of the typical large imbalanced medical datasets. We further use the meta-heuristic algorithms to optimize two key parameters of SMOTE. Leading to more credible performances of the classifier, and shortening the running time compared with the brute-force method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imbalanced%20dataset" title="Imbalanced dataset">Imbalanced dataset</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-heuristic%20algorithm" title=" meta-heuristic algorithm"> meta-heuristic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=SMOTE" title=" SMOTE"> SMOTE</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data "> big data </a> </p> <a href="https://publications.waset.org/abstracts/41481/adaptive-swarm-balancing-algorithms-for-rare-event-prediction-in-imbalanced-healthcare-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41481.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">441</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> Detecting Music Enjoyment Level Using Electroencephalogram Signals and Machine Learning Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Feng">Raymond Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadi%20Ghiasi"> Shadi Ghiasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An electroencephalogram (EEG) is a non-invasive technique that records electrical activity in the brain using scalp electrodes. Researchers have studied the use of EEG to detect emotions and moods by collecting signals from participants and analyzing how those signals correlate with their activities. In this study, researchers investigated the relationship between EEG signals and music enjoyment. Participants listened to music while data was collected. During the signal-processing phase, power spectral densities (PSDs) were computed from the signals, and dominant brainwave frequencies were extracted from the PSDs to form a comprehensive feature matrix. A machine learning approach was then taken to find correlations between the processed data and the music enjoyment level indicated by the participants. To improve on previous research, multiple machine learning models were employed, including K-Nearest Neighbors Classifier, Support Vector Classifier, and Decision Tree Classifier. Hyperparameters were used to fine-tune each model to further increase its performance. The experiments showed that a strong correlation exists, with the Decision Tree Classifier with hyperparameters yielding 85% accuracy. This study proves that EEG is a reliable means to detect music enjoyment and has future applications, including personalized music recommendation, mood adjustment, and mental health therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEG" title="EEG">EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=electroencephalogram" title=" electroencephalogram"> electroencephalogram</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=mood" title=" mood"> mood</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20enjoyment" title=" music enjoyment"> music enjoyment</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20signals" title=" physiological signals"> physiological signals</a> </p> <a href="https://publications.waset.org/abstracts/182307/detecting-music-enjoyment-level-using-electroencephalogram-signals-and-machine-learning-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182307.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">62</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> Absorbed Dose Measurements for Teletherapy Prediction of Superficial Dose Using Halcyon Linear Accelerator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Limen%20Njinga">Raymond Limen Njinga</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeneye%20Samuel%20Olaolu"> Adeneye Samuel Olaolu</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinyode%20Ojumoola%20Ajimo"> Akinyode Ojumoola Ajimo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Measurement of entrance dose and dose at different depths is essential to avoid overdose and underdose of patients. The aim of this study is to verify the variation in the absorbed dose using a water-equivalent material. Materials and Methods: The plastic phantom was arranged on the couch of the halcyon linear accelerator by Varian, with the farmer ionization chamber inserted and connected to the electrometer. The image of the setup was taken using the High-Quality Single 1280x1280x16 higher on the service mode to check the alignment with the isocenter. The beam quality TPR₂₀,₁₀ (Tissue phantom ratio) was done to check the beam quality of the machine at a field size of 10 cm x 10 cm. The calibration was done using SAD type set-up at a depth of 5 cm. This process was repeated for ten consecutive weeks, and the values were recorded. Results: The results of the beam output for the teletherapy machine were satisfactory and accepted in comparison with the commissioned measurement of 0.62. The beam quality TPR₂₀,₁₀ (Tissue phantom ratio) was reasonable with respect to the beam quality of the machine at a field size of 10 cm x 10 cm. Conclusion: The results of the beam quality and the absorbed dose rate showed a good consistency over the period of ten weeks with the commissioned measurement value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=linear%20accelerator" title="linear accelerator">linear accelerator</a>, <a href="https://publications.waset.org/abstracts/search?q=absorbed%20dose%20rate" title=" absorbed dose rate"> absorbed dose rate</a>, <a href="https://publications.waset.org/abstracts/search?q=isocenter" title=" isocenter"> isocenter</a>, <a href="https://publications.waset.org/abstracts/search?q=phantom" title=" phantom"> phantom</a>, <a href="https://publications.waset.org/abstracts/search?q=ionization%20chamber" title=" ionization chamber"> ionization chamber</a> </p> <a href="https://publications.waset.org/abstracts/183165/absorbed-dose-measurements-for-teletherapy-prediction-of-superficial-dose-using-halcyon-linear-accelerator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183165.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">61</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">33</span> A Critical Re-Evaluation of Knowledge Management Definitions and Terminologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Olayinka">Raymond Olayinka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The last three decades have witnessed myriads of definitions of knowledge management proposed by researchers and industry practitioners. Despite the magnitude of research and available literature on knowledge management, there is yet to be a consensus on what constitutes a good definition. There exists an in-exhaustive list of definitions which can appear confusing, conflicting and overlapping. What is even more daunting is the lack of common terminology in describing knowledge management processes and the inconsistency in the sequence in which the processes take. Whilst newbies to knowledge management research would struggle to make sense of knowledge management definitions, industry practitioners would struggle with their applicability. Against this backdrop, this study aimed to re-evaluate knowledge management definitions and terminologies. The objectives were threefold: (1) to conduct a critical review of an existing body of work around knowledge management concepts and definitions (2) to analyse and synthesise findings (3) to present conclusions and recommendations. The methodology for this study centres around the review of the literature and secondary data sources. A total of 48 knowledge management processes were found and extracted from various definitions (e.g. ‘identify’, ‘capture’, ‘codify’, ‘store’…). A taxonomy of the processes was created based on the commonality of the entities. The 48 processes were classified under 8 headings which were further converged into 3 main headings namely ‘acquire’, ‘exploit’ and ‘evaluate’, of which all definitions therefore hinge. The study concludes that in the multitude of knowledge management definitions, there is a consistent pattern to which the processes are organised and should be utilised. The contribution of this study is in the synthesis of previous work by various authors and the presentation of a more holistic approach to knowledge management definitions and terminologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management%20definitions" title="knowledge management definitions">knowledge management definitions</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management%20terminologies" title=" knowledge management terminologies"> knowledge management terminologies</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management%20processes" title=" knowledge management processes"> knowledge management processes</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a> </p> <a href="https://publications.waset.org/abstracts/106885/a-critical-re-evaluation-of-knowledge-management-definitions-and-terminologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106885.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">32</span> Study of Human Upper Arm Girth during Elbow Isokinetic Contractions Based on a Smart Circumferential Measuring System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xi%20Wang">Xi Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoming%20Tao"> Xiaoming Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Raymond%20C.%20H.%20So"> Raymond C.

The sensing validity has been elaborated by preliminary researches but still need more fundamental study, especially on kinetic contraction modes. Based on the novel fabric strain sensors, a soft and smart limb girth measurement system was developed by the authors’ group, which can measure the limb girth in-motion. Experiments were carried out on elbow isometric flexion and elbow isokinetic flexion (biceps’ isokinetic contractions) of 90°/s, 60°/s, and 120°/s for 10 subjects (2 canoeists and 8 ordinary people). After removal of natural circumferential increments due to elbow position, the joint torque is found not uniformly sensitive to the limb circumferential strains, but declining as elbow joint angle rises, regardless of the angular speed. Moreover, the maximum joint torque was found as an exponential function of the joint’s angular speed. This research highly contributes to the application of the automatic limb girth measuring during kinetic contractions, and it is useful to predict the contraction level of voluntary skeletal muscles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fabric%20strain%20sensor" title="fabric strain sensor">fabric strain sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20deformation" title=" muscle deformation"> muscle deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=isokinetic%20contraction" title=" isokinetic contraction"> isokinetic contraction</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20torque" title=" joint torque"> joint torque</a>, <a href="https://publications.waset.org/abstracts/search?q=limb%20girth%20strain" title=" limb girth strain"> limb girth strain</a> </p> <a href="https://publications.waset.org/abstracts/39596/study-of-human-upper-arm-girth-during-elbow-isokinetic-contractions-based-on-a-smart-circumferential-measuring-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39596.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">337</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> Infodemic Detection on Social Media with a Multi-Dimensional Deep Learning Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Xu">Raymond Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cindy%20Jingru%20Wang"> Cindy Jingru Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social media has become a globally connected and influencing platform. Social media data, such as tweets, can help predict the spread of pandemics and provide individuals and healthcare providers early warnings. Public psychological reactions and opinions can be efficiently monitored by AI models on the progression of dominant topics on Twitter. However, statistics show that as the coronavirus spreads, so does an infodemic of misinformation due to pandemic-related factors such as unemployment and lockdowns. Social media algorithms are often biased toward outrage by promoting content that people have an emotional reaction to and are likely to engage with. This can influence users’ attitudes and cause confusion. Therefore, social media is a double-edged sword. Combating fake news and biased content has become one of the essential tasks. This research analyzes the variety of methods used for fake news detection covering random forest, logistic regression, support vector machines, decision tree, naive Bayes, BoW, TF-IDF, LDA, CNN, RNN, LSTM, DeepFake, and hierarchical attention network. The performance of each method is analyzed. Based on these models’ achievements and limitations, a multi-dimensional AI framework is proposed to achieve higher accuracy in infodemic detection, especially pandemic-related news. The model is trained on contextual content, images, and news metadata. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=fake%20news%20detection" title=" fake news detection"> fake news detection</a>, <a href="https://publications.waset.org/abstracts/search?q=infodemic%20detection" title=" infodemic detection"> infodemic detection</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20recognition" title=" image recognition"> image recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=sentiment%20analysis" title=" sentiment analysis"> sentiment analysis</a> </p> <a href="https://publications.waset.org/abstracts/137238/infodemic-detection-on-social-media-with-a-multi-dimensional-deep-learning-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137238.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">254</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> Student Attribute and the Effectiveness of Classroom Response System in Teaching Economics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Li">Raymond Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this project a web-based classroom response system (CRS) was used in the teaching an intermediate level economics course. This system allows the instructor to post a question on the screen and students to answer questions using their own electronic mobile devices. The questions and the results summarizing student responses can be shown to students simultaneously and the instructor can make timely feedback to students in class. CRS gives students a chance to respond to the instructor’s question privately, encouraging students who might not typically speak up in class to express their thoughts and opinions. There is a vast literature on the advantages and challenges of using CRS. However, empirical evidence on the student attributes that increase the effectiveness of CRS in improving student learning outcomes is sparse. The purpose of this project is to (1) find out if the use of CRS is beneficial to students taking economics, and (2) discover key student attributes that will likely make CRS more effective. Students’ performance in examinations and an end-of-semester questionnaire were used to assess the effectiveness of CRS in this project. Comparing the examination scores of the CRS treatment group and control group, the treatment group performed considerably better and statistically significant differences were found basing on paired t-tests on the differences. According to the questionnaire results, around 75% of the students in the treatment group generally agreed that CRS allowed them to express their views more freely. We also observed that students who prefer to use instant messaging rather than making conversations are generally more positive towards CRS. The use of CRS also benefits the instructor – students’ rating of the instructor in the teaching evaluation was significantly higher for the CRS treatment group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education%20technology" title="education technology">education technology</a>, <a href="https://publications.waset.org/abstracts/search?q=classroom%20response%20system" title=" classroom response system"> classroom response system</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20attributes" title=" student attributes"> student attributes</a>, <a href="https://publications.waset.org/abstracts/search?q=economics%20education" title=" economics education"> economics education</a> </p> <a href="https://publications.waset.org/abstracts/103651/student-attribute-and-the-effectiveness-of-classroom-response-system-in-teaching-economics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103651.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">126</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> Early Depression Detection for Young Adults with a Psychiatric and AI Interdisciplinary Multimodal Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Xu">Raymond Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashley%20Hua"> Ashley Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Wang"> Andrew Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuru%20Lin"> Yuru Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During COVID-19, the depression rate has increased dramatically. Young adults are most vulnerable to the mental health effects of the pandemic. Lower-income families have a higher ratio to be diagnosed with depression than the general population, but less access to clinics. This research aims to achieve early depression detection at low cost, large scale, and high accuracy with an interdisciplinary approach by incorporating clinical practices defined by American Psychiatric Association (APA) as well as multimodal AI framework. The proposed approach detected the nine depression symptoms with Natural Language Processing sentiment analysis and a symptom-based Lexicon uniquely designed for young adults. The experiments were conducted on the multimedia survey results from adolescents and young adults and unbiased Twitter communications. The result was further aggregated with the facial emotional cues analyzed by the Convolutional Neural Network on the multimedia survey videos. Five experiments each conducted on 10k data entries reached consistent results with an average accuracy of 88.31%, higher than the existing natural language analysis models. This approach can reach 300+ million daily active Twitter users and is highly accessible by low-income populations to promote early depression detection to raise awareness in adolescents and young adults and reveal complementary cues to assist clinical depression diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=depression%20detection" title=" depression detection"> depression detection</a>, <a href="https://publications.waset.org/abstracts/search?q=psychiatric%20disorder" title=" psychiatric disorder"> psychiatric disorder</a> </p> <a href="https://publications.waset.org/abstracts/136275/early-depression-detection-for-young-adults-with-a-psychiatric-and-ai-interdisciplinary-multimodal-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136275.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">131</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> Reconceptualising Faculty Teaching Competence: The Role of Agency during the Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ida%20Fatimawati%20Adi%20Badiozaman">Ida Fatimawati Adi Badiozaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Augustus%20Raymond%20Segar"> Augustus Raymond Segar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Covid-19 pandemic transformed teaching contexts at an unprecedented level. Although studies have focused mainly on its impact on students, little is known about how emergency online teaching affects faculty members in higher education. Given that the pandemic has robbed teachers of opportunities for adequate preparation, it is vital to understand how teaching competencies were perceived in the crisis-response transition to online teaching and learning (OTL). Therefore, the study explores how academics perceive their readiness for OTL and what competencies were perceived to be central. Therefore, through a mixed-methods design, the study first explores through a survey how academics perceive their readiness for OTL and what competencies were perceived to be central. Emerging trends from the quantitative data of 330 academics (three public and three private Higher learning institutions) led to the formulation of interview guides for the subsequent qualitative phase. The authors use critical sensemaking (CSM) to analyse interviews with twenty-two teachers (n = 22) (three public; three private HEs) toward understanding the interconnected layers of influences they draw from as they make sense of their teaching competence. The sensemaking process reframed competence and readiness in that agentic competency emerged as crucial in shaping resilience and adaptability during the transition to OTL. The findings also highlight professional learningcriticalto teacher competence: course design, communication, time management, technological competence, and identity (re)construction. The findings highlight opportunities for strategic orientation to change during crisis.

The juvenile justice system is meant to protect young offenders from physical, emotional and mental exploitation by adult prisoners. Under-age young offenders should be assisted and exposed to educational, entrepreneurial and behavioral programmes that can equip them with the much needed skills that will turn them into law-abiding and economically productive citizens. The aim of this study was to evaluate the effectiveness of the justice system in South Africa in the rehabilitation young offenders. A qualitative method was used. The study used the non-probability purposive sampling to select the respondents. In-depth interviews, focus groups, observation and thematic coding were used to collect and analyse the data respectively. The study population consisted of social workers and offending youth. The sample comprised of 16 respondents (i.e. 4 social workers and twelve offending youth (6 males and 6 females). The study indicated that there is worrying recurrence of the anti-social behavior by some of the young offenders. According to this study, the effectiveness of the juvenile justice system in the rehabilitation of the offending youth can be achieved by paying serious attention to follow-up services, participation of families of the offending youth in the diversion programmes and by improving the socio-economic conditions in the homes and communities of the offending youth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=juvenile%20delinquent" title="juvenile delinquent">juvenile delinquent</a>, <a href="https://publications.waset.org/abstracts/search?q=juvenile%20justice%20system" title=" juvenile justice system"> juvenile justice system</a>, <a href="https://publications.waset.org/abstracts/search?q=diversion%20programmes" title=" diversion programmes"> diversion programmes</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=restorative%20justice" title=" restorative justice"> restorative justice</a> </p> <a href="https://publications.waset.org/abstracts/43904/an-evaluation-of-the-effectiveness-of-the-juvenile-justice-in-rehabilitating-the-youth-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43904.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 Role of Phycoremediation in the Sustainable Management of Aquatic Pollution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Ezenweani">Raymond Ezenweani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Ogbebor"> Jeffrey Ogbebor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The menace of aquatic pollution has become increasingly of great concern and the effects of this pollution as a result of anthropogenic activities cannot be over emphasized. Phycoremediation is the application of algal remediation technology in the removal of harmful products from the environment. Harmful products also known as pollutants are usually introduced into the environment through variety of processes such as industrial discharge, agricultural runoff, flooding, and acid rain. This work has to do with the capability of algae in the efficient removal of different pollutants, ranging from hydrocarbons, eutrophication, agricultural chemicals and wastes, heavy metals, foul smell from septic tanks or dumps through different processes such as bioconversion, biosorption, bioabsorption and biodecomposition. Algae are capable of bioconversion of environmentally persistent compounds to degradable compounds and also capable of putting harmful bacteria growth into check in waste water remediation. Numerous algal organisms such as Nannochloropsis spp, Chlorella spp, Tetraselmis spp, Shpaerocystics spp, cyanobacteria and different macroalgae have been tested by different researchers in laboratory scale and shown to have 100% efficiency in environmental remediation. Algae as a result of their photosynthetic capacity are also efficient in air cleansing and management of global warming by sequestering carbon iv oxide in air and converting it into organic carbon, thereby making food available for the other organisms in the higher trophic level of the aquatic food chain. Algae play major role in the sustenance of the aquatic ecosystem by their virtue of being photosynthetic. They are the primary producers and their role in environmental sustainability is remarkable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algae" title="Algae ">Algae </a>, <a href="https://publications.waset.org/abstracts/search?q=Pollutant" title=" Pollutant"> Pollutant</a>, <a href="https://publications.waset.org/abstracts/search?q=." title=".">.</a>, <a href="https://publications.waset.org/abstracts/search?q=Phycoremediation" title=" Phycoremediation"> Phycoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=Aquatic" title=" Aquatic"> Aquatic</a>, <a href="https://publications.waset.org/abstracts/search?q=Sustainability" title=" Sustainability"> Sustainability</a> </p> <a href="https://publications.waset.org/abstracts/120451/the-role-of-phycoremediation-in-the-sustainable-management-of-aquatic-pollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120451.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">126</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">25</span> Indian Christian View of God: Exploring Its Trajectory in 20th Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=James%20Ponniah">James Ponniah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Christianity is the largest religious tradition of the world. What makes Christianity a world religion is its characteristics of universality and particularity. Its universality and particularity are closely interrelated. Its university is realized and embodied in its particularities and its particularity is recognized and legitimized through its universality. This paper focuses on the dimension of the particularity of Christianity in that it looks at the particularized ideas and discourses of Christian thinking in India in the 20th century and pays attention to the differing shifts and new shades of meaning in Indian Christian notion of God. Drawing upon the writings of select Indian theologians such as Brahmabandhab Upadhyaya, Sundar Sing, A.J Appasamy, Raymond Panikkar, Amalorpavadass and George Soares Prabhhu, this paper delves into how the contexts—be it personal, political, historical or ecclesial—bear upon the way Indian theologians have conceived and constructed the notion of God in their work. Focusing upon how they responded to the signs of their time through their theological narratives, the paper argues that the religion of Christianity can sustain its universality only when it translates its key notions such as God into indigenous categories and local idioms and thus makes itself relevant to the people among whom it is spread. Monotheistic God of Christianity has to accommodate plurality of expressions if Christian idea God has to capture and convey everyone’s experience of God. The case of Indian Christianity then reveals that a monolithic world religion will be experienced and recognised as truly universal only when it sheds its homogeneity and assumes a heterogeneous portrait through the acquisition of local idioms. Allowing culturally diverse idioms to influence theological categories is not inconsequential to—‘accommodating differences and accepting diversities,’ an issue we encounter within and beyond religious domains in our contemporary times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concept%20of%20God" title="concept of
