in Meaningless Data: Why It Is Unconstitutional to Use Life Expectancy Tables in Post-Graham Sentences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stacie%20Nelson%20Colling">Stacie Nelson Colling</a>, <a href="https://publications.waset.org/abstracts/search?q=Adele%20Cummings"> Adele Cummings</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The United States Supreme Court recently announced that it is unconstitutional to sentence a child to life without parole for non-homicide offenses, and that each child so situated must be afforded a meaningful opportunity for release from prison in his lifetime. The Court also declared that it is unconstitutional to impose a mandatory sentence of life without parole on a child for homicide offenses. Across the United States, attorneys and advocates continue to litigate issues surrounding the implementation of these legal principles. Some states have held that any sentence to a finite term of years, no matter how long, is not the same as ‘life’ and therefore does not violate the constitution. Other states have held that a sentence to a term of years that is less than the expected life of that particular child is not unconstitutional. In Colorado, the courts have routinely looked to life expectancy estimates from governmental organizations to determine how long a particular child is expected to live. They then compare that the date that the child is expected to be eligible for parole, and if the child is expected to still be living when he is eligible for parole, the sentence is deemed constitutional. This paper argues that it is inappropriate, reckless, unconstitutional and not scientifically sound to use such estimates in determining whether a child will have a meaningful opportunity for release from prison and life outside of prison before he dies. This paper argues that the opportunity for release must mean more than a probability that a child will be released before his death, and that it must include an opportunity for a meaningful life outside of prison (not just the opportunity to be released and then die on the outside). The paper further argues that life expectancy estimates cannot guide a court or a legislature in determining whether a sentence is or is not constitutional. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=life%20without%20parole" title="life without parole">life without parole</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20expectancy" title=" life expectancy"> life expectancy</a>, <a href="https://publications.waset.org/abstracts/search?q=juvenile%20sentencing" title=" juvenile sentencing"> juvenile sentencing</a>, <a href="https://publications.waset.org/abstracts/search?q=meaningful%20opportunity%20for%20release%20from%20prison" title=" meaningful opportunity for release from prison"> meaningful opportunity for release from prison</a> </p> <a href="https://publications.waset.org/abstracts/39478/there-is-no-meaningful-opportunity-in-meaningless-data-why-it-is-unconstitutional-to-use-life-expectancy-tables-in-post-graham-sentences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39478.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">394</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">104</span> The Ability of Forecasting the Term Structure of Interest Rates Based on Nelson-Siegel and Svensson Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tea%20Poklepovi%C4%87">Tea Poklepović</a>, <a href="https://publications.waset.org/abstracts/search?q=Zdravka%20Aljinovi%C4%87"> Zdravka Aljinović</a>, <a href="https://publications.waset.org/abstracts/search?q=Branka%20Marasovi%C4%87"> Branka Marasović</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the importance of yield curve and its estimation it is inevitable to have valid methods for yield curve forecasting in cases when there are scarce issues of securities and/or week trade on a secondary market. Therefore in this paper, after the estimation of weekly yield curves on Croatian financial market from October 2011 to August 2012 using Nelson-Siegel and Svensson models, yield curves are forecasted using Vector auto-regressive model and Neural networks. In general, it can be concluded that both forecasting methods have good prediction abilities where forecasting of yield curves based on Nelson Siegel estimation model give better results in sense of lower Mean Squared Error than forecasting based on Svensson model Also, in this case Neural networks provide slightly better results. Finally, it can be concluded that most appropriate way of yield curve prediction is neural networks using Nelson-Siegel estimation of yield curves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nelson-Siegel%20Model" title="Nelson-Siegel Model">Nelson-Siegel Model</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=Svensson%20Model" title=" Svensson Model"> Svensson Model</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20autoregressive%20model" title=" vector autoregressive model"> vector autoregressive model</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20curve" title=" yield curve"> yield curve</a> </p> <a href="https://publications.waset.org/abstracts/2460/the-ability-of-forecasting-the-term-structure-of-interest-rates-based-on-nelson-siegel-and-svensson-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2460.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">333</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">103</span> A Hybrid Particle Swarm Optimization-Nelder- Mead Algorithm (PSO-NM) for Nelson-Siegel- Svensson Calibration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sofia%20Ayouche">Sofia Ayouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Ellaia"> Rachid Ellaia</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajae%20Aboulaich"> Rajae Aboulaich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, insurers may use the yield curve as an indicator evaluation of the profit or the performance of their portfolios; therefore, they modeled it by one class of model that has the ability to fit and forecast the future term structure of interest rates.

Unfortunately, many authors have reported a lot of difficulties when they want to calibrate the model because the optimization problem is not convex and has multiple local optima. In this context, we implement a hybrid Particle Swarm optimization and Nelder Mead algorithm in order to minimize by least squares method, the difference between the zero-coupon curve and the NSS curve. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-coupon%20curve" title=" zero-coupon curve"> zero-coupon curve</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson-Siegel-Svensson" title=" Nelson-Siegel-Svensson"> Nelson-Siegel-Svensson</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelder-Mead%20algorithm" title=" Nelder-Mead algorithm"> Nelder-Mead algorithm</a> </p> <a href="https://publications.waset.org/abstracts/48619/a-hybrid-particle-swarm-optimization-nelder-mead-algorithm-pso-nm-for-nelson-siegel-svensson-calibration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48619.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">430</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">102</span> Modelling the Indonesian Goverment Securities Yield Curve Using Nelson-Siegel-Svensson and Support Vector Regression </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamilatuzzahro">Jamilatuzzahro</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezzy%20Eko%20Caraka"> Rezzy Eko Caraka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The yield curve is the plot of the yield to maturity of zero-coupon bonds against maturity. In practice, the yield curve is not observed but must be extracted from observed bond prices for a set of (usually) incomplete maturities. There exist many methodologies and theory to analyze of yield curve. We use two methods (the Nelson-Siegel Method, the Svensson Method, and the SVR method) in order to construct and compare our zero-coupon yield curves. The objectives of this research were: (i) to study the adequacy of NSS model and SVR to Indonesian government bonds data, (ii) to choose the best optimization or estimation method for NSS model and SVR. To obtain that objective, this research was done by the following steps: data preparation, cleaning or filtering data, modeling, and model evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20regression" title="support vector regression">support vector regression</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson-Siegel-Svensson" title=" Nelson-Siegel-Svensson"> Nelson-Siegel-Svensson</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20curve" title=" yield curve"> yield curve</a>, <a href="https://publications.waset.org/abstracts/search?q=Indonesian%20government" title=" Indonesian government"> Indonesian government</a> </p> <a href="https://publications.waset.org/abstracts/63081/modelling-the-indonesian-goverment-securities-yield-curve-using-nelson-siegel-svensson-and-support-vector-regression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63081.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">244</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">101</span> The Term Structure of Government Bond Yields in an Emerging Market: Empirical Evidence from Pakistan Bond Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wali%20Ullah">Wali Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nishat"> Muhammad Nishat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigates the extent to which the so called Nelson-Siegel model (DNS) and its extended version that accounts for time varying volatility (DNS-EGARCH) can optimally fit the yield curve and predict its future path in the context of an emerging economy.

Moreover, both specifications of yield curve that are based on the Nelson-Siegel functional form outperform the benchmark VAR forecasts at all forecast horizons. The DNS-EGARCH comes with more precise forecasts than the DNS for the 6- and 12-month ahead forecasts, while the two have almost similar performance in terms of RMSE for the very short forecast horizons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=yield%20curve" title="yield curve">yield curve</a>, <a href="https://publications.waset.org/abstracts/search?q=forecasting" title=" forecasting"> forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20markets" title=" emerging markets"> emerging markets</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a>, <a href="https://publications.waset.org/abstracts/search?q=EGARCH" title=" EGARCH"> EGARCH</a> </p> <a href="https://publications.waset.org/abstracts/17242/the-term-structure-of-government-bond-yields-in-an-emerging-market-empirical-evidence-from-pakistan-bond-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17242.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">539</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">100</span> Zero Valent Iron Algal Biocomposite for the Removal of Crystal Violet from Aqueous Solution: Box-Behnken Optimization and Fixed Bed Column Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Jerold">M.

The Box-Behnen design (BBD) experimental results revealed the biosoprtion was maximum at pH 7.5, biosorbent dosage 0.1 g/L and initial CV concentration of 100 mg/L. The effect of various column parameters like bed depth (3, 6 and 9 cm), flow rate (5, 10 and 15 mL/min) and influent CV concentration (5, 10 and 15 mg/L) were investigated. The exhaustion time increased with increase of bed depth, influent CV concentration and decrease of flow rate. Adam-Bohart, Thomas and Yoon-Nelson models were used to predict the breakthrough curve and to evaluate the model parameters. Out of these models, Thomas and Yoon-Nelson models well described the experimental data. Therefore, the result implies that nZVI-SS biocomposite is a cheap and most promising biosorbent for the removal of CV from wastewater. <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=biosorption" title=" biosorption"> biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-valent" title=" zero-valent"> zero-valent</a>, <a href="https://publications.waset.org/abstracts/search?q=dye" title=" dye"> dye</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/114454/zero-valent-iron-algal-biocomposite-for-the-removal-of-crystal-violet-from-aqueous-solution-box-behnken-optimization-and-fixed-bed-column-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">99</span> Developing and Enacting a Model for Institutional Implementation of the Humanizing Pedagogy: Case Study of Nelson Mandela University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukhtar%20Raban">Mukhtar Raban</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As part of Nelson Mandela University’s journey of repositioning its learning and teaching agenda, the university adopted and foregrounded a humanizing pedagogy-aligning with institutional goals of critically transforming the academic project. The university established the Humanizing Pedagogy Praxis and Research Niche (HPPRN) as a centralized hub for coordinating institutional work exploring and advancing humanizing pedagogies and tasked the unit with developing and enacting a model for humanizing pedagogy exploration. This investigation endeavored to report on the development and enactment of a model that sought to institutionalize a humanizing pedagogy at a South African university. Having followed a qualitative approach, the investigation presents the case study of Nelson Mandela University’s HPPRN and the model it subsequently established and enacted for the advancement towards a more common institutional understanding, interpretation and application of the humanizing pedagogy. The study adopted an interpretive lens for analysis, complementing the qualitative approach of the investigation. The primary challenge that confronted the HPPRN was the development of a ‘living model’ that had to complement existing institutional initiatives while accommodating a renewed spirit of critical reflection, innovation and research of continued and new humanizing pedagogical exploration and applications. The study found that the explicit consideration of tenets of humanizing and critical pedagogies in underpinning and framing the HPPRN Model contributed to the sense of ‘lived’ humanizing pedagogy experiences during enactment. The multi-leveled inclusion of critical reflection in the development and enactment stages was found to further the processes of praxis employed at the university, which is integral to the advancement of humanizing and critical pedagogies. The development and implementation of a model that seeks to institutionalize the humanizing pedagogy at a university rely not only on sound theoretical conceptualization but also on the ‘richness of becoming more human’ explicitly expressed and encountered in praxes and application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=humanizing%20pedagogy" title="humanizing pedagogy">humanizing pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20pedagogy" title=" critical pedagogy"> critical pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20implementation" title=" institutional implementation"> institutional implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=praxis" title=" praxis"> praxis</a> </p> <a href="https://publications.waset.org/abstracts/108430/developing-and-enacting-a-model-for-institutional-implementation-of-the-humanizing-pedagogy-case-study-of-nelson-mandela-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108430.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">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">98</span> Continuous Fixed Bed Reactor Application for Decolourization of Textile Effluent by Adsorption on NaOH Treated Eggshell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Chafi">M.

Various low cost adsorbents have been studied for their applicability in treatment of different types of effluents. In this work, the intention of the study was to explore the efficacy and feasibility for azo dye, Acid Orange 7 (AO7) adsorption onto fixed bed column of NaOH Treated eggshell (TES). The effect of various parameters like flow rate, initial dye concentration, and bed height were exploited in this study. The studies confirmed that the breakthrough curves were dependent on flow rate, initial dye concentration solution of AO7 and bed depth. The Thomas, Yoon–Nelson, and Adams and Bohart models were analysed to evaluate the column adsorption performance. The adsorption capacity, rate constant and correlation coefficient associated to each model for column adsorption was calculated and mentioned. The column experimental data were fitted well with Thomas model with coefficients of correlation R2 ≥0.93 at different conditions but the Yoon–Nelson, BDST and Bohart–Adams model (R2=0.911), predicted poor performance of fixed-bed column.

Most higher education institutions worldwide had to shift from traditional face-to-face to online learning. The online environment and new online tools are disrupting the way in which higher education is presented. Furthermore, the structures of higher education institutions have been impacted by rapid advancements in information and communication technologies. Emerging technologies should not be viewed in a negative light because, as opposed to the traditional curriculum that worked to create productive and efficient researchers, emerging technologies encourage creativity and innovation. Therefore, using technology together with traditional means will enhance teaching and learning. Emerging technologies in higher education not only change the experience of students, lecturers, and the content, but it is also influencing the attraction and retention of students. Higher education institutions are under immense pressure because not only are they competing locally and nationally, but emerging technologies also expand the competition internationally. Emerging technologies have eliminated border barriers, allowing students to study in the country of their choice regardless of where they are in the world. Higher education institutions are becoming indifferent as technology is finding its way into the lecture room day by day. Academics need to utilise technology at their disposal if they want to get through to their students. Academics are now competing for students' attention with social media platforms such as WhatsApp, Snapchat, Instagram, Facebook, TikTok, and others. This is posing a significant challenge to higher education institutions. It is, therefore, critical to pay attention to emerging technologies in order to see how they can be incorporated into the classroom in order to improve educational quality while remaining relevant in the work industry. This study aims to understand how emerging technologies have been utilised at Nelson Mandela University in presenting teaching and learning activities since April 2020. The primary objective of this study is to analyse how academics are incorporating emerging technologies in their teaching and learning activities. This primary objective was achieved by conducting a literature review on clarifying and conceptualising the emerging technologies being utilised by higher education institutions, reviewing and analysing the use of emerging technologies, and will further be investigated through an empirical analysis of the use of emerging technologies at Nelson Mandela University. Findings from the literature review revealed that emerging technology is impacting several key areas in higher education institutions, such as the attraction and retention of students, enhancement of teaching and learning, increase in global competition, elimination of border barriers, and highlighting the digital divide. The literature review further identified that learning management systems, open educational resources, learning analytics, and artificial intelligence are the most prevalent emerging technologies being used in higher education institutions. The identified emerging technologies will be further analysed through an empirical analysis to identify how they are being utilised at Nelson Mandela University. <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=emerging%20technologies" title=" emerging technologies"> emerging technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20analytics" title=" learning analytics"> learning analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=learner%20management%20systems" title=" learner management systems"> learner management systems</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20educational%20resources" title=" open educational resources"> open educational resources</a> </p> <a href="https://publications.waset.org/abstracts/146630/the-use-of-emerging-technologies-in-higher-education-institutions-a-case-of-nelson-mandela-university-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146630.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">69</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">96</span> Waterborne Platooning: Cost and Logistic Analysis of Vessel Trains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alina%20P.%20Colling">Alina P.

Its main benefits are the improvement of traffic stability and the reduction of air drag, resulting in less fuel consumption, in comparison to using individual trucks. Platooning is now being adapted to the waterborne transport sector in the NOVIMAR project through the development of a Vessel Train (VT) concept. The main focus of VT’s, as opposed to the truck platoons, is the decrease in manning on board, ultimately working towards autonomous vessel operations. This crew reduction can prove to be an important selling point in achieving economic competitiveness of the waterborne approach when compared to alternative modes of transport. This paper discusses the expected benefits and drawbacks of the VT concept, in terms of the technical logistic performance and generalized costs. More specifically, VT’s can provide flexibility in destination choices for shippers but also add complexity when performing special manoeuvres in VT formation. In order to quantify the cost and performances, a model is developed and simulations are carried out for various case studies. These compare the application of VT’s in the short sea and inland water transport, with specific sailing regimes and technologies installed on board to allow different levels of autonomy. The results enable the identification of the most important boundary conditions for the successful operation of the waterborne platooning concept. These findings serve as a framework for future business applications of the VT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20vessels" title="autonomous vessels">autonomous vessels</a>, <a href="https://publications.waset.org/abstracts/search?q=NOVIMAR" title=" NOVIMAR"> NOVIMAR</a>, <a href="https://publications.waset.org/abstracts/search?q=vessel%20trains" title=" vessel trains"> vessel trains</a>, <a href="https://publications.waset.org/abstracts/search?q=waterborne%20platooning" title=" waterborne platooning"> waterborne platooning</a> </p> <a href="https://publications.waset.org/abstracts/88355/waterborne-platooning-cost-and-logistic-analysis-of-vessel-trains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88355.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">222</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">95</span> Comparison of Adsorbents for Ammonia Removal from Mining Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Al-Sheikh">F.

Elkamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ammonia in mining wastewater is a significant problem, and treatment can be especially difficult in cold climates where biological treatment is not feasible. An adsorption process is one of the alternative processes that can be used to reduce ammonia concentrations to acceptable limits, and therefore a LEWATIT resin strongly acidic H+ form ion exchange resin and a Bowie Chabazite Na form AZLB-Na zeolite were tested to assess their effectiveness. For these adsorption tests, two packed bed columns (a mini-column constructed from a 32-cm long x 1-cm diameter piece of glass tubing, and a 60-cm long x 2.5-cm diameter Ace Glass chromatography column) were used containing varying quantities of the adsorbents. A mining wastewater with ammonia concentrations of 22.7 mg/L was fed through the columns at controlled flowrates. In the experimental work, maximum capacities of the LEWATIT ion exchange resin were 0.438, 0.448, and 1.472 mg/g for 3, 6, and 9 g respectively in a mini column and 1.739 mg/g for 141.5 g in a larger Ace column while the capacities for the AZLB-Na zeolite were 0.424, and 0.784 mg/g for 3, and 6 g respectively in the mini column and 1.1636 mg/g for 38.5 g in the Ace column. In the theoretical work, Thomas, Adams-Bohart, and Yoon-Nelson models were constructed to describe a breakthrough curve of the adsorption process and find the constants of the above-mentioned models. In the regeneration tests, 5% hydrochloric acid, HCl (v/v) and 10% sodium hydroxide, NaOH (w/v) were used to regenerate the LEWATIT resin and AZLB-Na zeolite with 44 and 63.8% recovery, respectively. In conclusion, continuous flow adsorption using a LEWATIT ion exchange resin and an AZLB-Na zeolite is efficient when using a co-flow technique for removal of the ammonia from wastewater. Thomas, Adams-Bohart, and Yoon-Nelson models satisfactorily fit the data with R<sup>2</sup> closer to 1 in all cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AZLB-Na%20zeolite" title="AZLB-Na zeolite">AZLB-Na zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20adsorption" title=" continuous adsorption"> continuous adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Lewatit%20resin" title=" Lewatit resin"> Lewatit resin</a>, <a href="https://publications.waset.org/abstracts/search?q=models" title=" models"> models</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a> </p> <a href="https://publications.waset.org/abstracts/78618/comparison-of-adsorbents-for-ammonia-removal-from-mining-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78618.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">389</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">94</span> A Simple User Administration View of Computing Clusters </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valeria%20M.%20Bastos">Valeria M.

Melariri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schistosomiasis, caused by Schistosoma (S.) haematobium and Schistosoma (S.) mansoni parasites poses a significant public health challenge in low-income regions. Diagnosis typically relies on identifying specific urine biomarkers such as haematuria, protein, and leukocytes for S. haematobium, while the Point-of-Care Circulating Cathodic Antigen (POC-CCA) assay is employed for detecting S. mansoni. Urinalysis and the POC-CCA assay are favoured for their rapid, non-invasive nature and cost-effectiveness. However, traditional diagnostic methods such as Kato-Katz and urine filtration lack sensitivity in low-transmission areas, which can lead to underreporting of cases and hinder effective disease control efforts. Therefore, in this study, urinalysis and the POC-CCA assay was utilised to diagnose schistosomiasis effectively among school-going children in Nelson Mandela Bay Municipality. This was a cross-sectional study with a total of 759 children, aged 5 to 14 years, who provided urine samples. Urinalysis was performed using urinary dipstick tests, which measure multiple parameters, including haematuria, protein, leukocytes, bilirubin, urobilinogen, ketones, pH, specific gravity and other biomarkers. Urinalysis was performed by dipping the strip into the urine sample and observing colour changes on specific reagent pads. The POC-CCA test was conducted by applying a drop of urine onto a cassette containing CCA-specific antibodies, and the presence of a visible test line indicated a positive result for S. mansoni infection. Descriptive statistics were used to summarize urine parameters, and Pearson correlation coefficients (r) were calculated to analyze associations among urine parameters using R software (version 4.3.1). Among the 759 children, the prevalence of S. haematobium using haematuria as a diagnostic marker was 33.6%. Additionally, leukocytes were detected in 21.3% of the samples, and protein was present in 15%. The prevalence of positive POC-CCA test results for S. mansoni was 3.7%. Urine parameters exhibited low to moderate associations, suggesting complex interrelationships. For instance, specific gravity and pH showed a negative correlation (r = -0.37), indicating that higher specific gravity was associated with lower pH. Weak correlations were observed between haematuria and pH (r = -0.10), bilirubin and ketones (r = 0.14), protein and bilirubin (r = 0.13), and urobilinogen and pH (r = 0.12). A mild positive correlation was found between leukocytes and blood (r = 0.23), reflecting some association between these inflammation markers. In conclusion, the study identified a significant prevalence of schistosomiasis among school-going children in Nelson Mandela Bay Municipality, with S. haematobium detected through haematuria and S. mansoni identified using the POC-CCA assay. The detection of leukocytes and protein in urine samples serves as critical biomarkers for schistosomiasis infections, reinforcing the presence of schistosomiasis in the study area when considered alongside haematuria. These urine parameters are indicative of inflammatory responses associated with schistosomiasis, underscoring the necessity for effective diagnostic methodologies. Such findings highlight the importance of comprehensive diagnostic assessments to accurately identify and monitor schistosomiasis prevalence and its associated health impacts. The significant burden of schistosomiasis in this population highlights the urgent need to develop targeted control interventions to effectively reduce its prevalence in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schistosomiasis" title="schistosomiasis">schistosomiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=urinalysis" title=" urinalysis"> urinalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=haematuria" title=" haematuria"> haematuria</a>, <a href="https://publications.waset.org/abstracts/search?q=POC-CCA" title=" POC-CCA"> POC-CCA</a> </p> <a href="https://publications.waset.org/abstracts/192164/prevalence-and-diagnostic-evaluation-of-schistosomiasis-in-school-going-children-in-nelson-mandela-bay-municipality-insights-from-urinalysis-and-point-of-care-testing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192164.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">20</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">92</span> Microclimate Variations in Rio de Janeiro Related to Massive Public Transportation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20E.%20O.%20Jardim">Marco E.

The results allow the design engineer to pre-determine the flow rate and efficiency of the system to suit particular application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title="photovoltaic">photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pumping" title=" water pumping"> water pumping</a>, <a href="https://publications.waset.org/abstracts/search?q=losses" title=" losses"> losses</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20motor" title=" induction motor"> induction motor</a> </p> <a href="https://publications.waset.org/abstracts/45964/optimal-operation-of-a-photovoltaic-induction-motor-drive-water-pumping-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45964.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">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">88</span> The Chemistry in the Video Game No Man’s Sky</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Santos">Diogo Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Zagalo"> Nelson Zagalo</a>, <a href="https://publications.waset.org/abstracts/search?q=Carla%20Morais"> Carla Morais</a> </p> <p class="card-text"><strong>Abstract:</strong></p> No Man’s Sky (NMS) is a sci-fi video game about survival and exploration where players fly spaceships, search for elements, and use them to survive. NMS isn’t a serious game, and not all the science in the game is presented with scientific evidence. To find how players felt about the scientific content in the game and how they perceive the chemistry in it, a survey was sent to NMS’s players, from which were collected answers from 124 respondents from 23 countries. Chemophobia is still a phenomenon when chemistry or chemicals are a subject of discussion, but 68,9% of our respondents showed a positive attitude towards the presence of chemistry in NMS, with 57% stating that playing the video game motivated them to know more about science. 8% of the players stated that NMS often prompted conversations about the science in the video game between them and teachers, parents, or friends. These results give us ideas on how an entertainment game can potentially help scientists, educators, and science communicators reach a growing, evolving, vibrant, diverse, and demanding audience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20games" title="digital games">digital games</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20communication" title=" science communication"> science communication</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20learning" title=" informal learning"> informal learning</a>, <a href="https://publications.waset.org/abstracts/search?q=No%20Man%E2%80%99s%20Sky" title=" No Man’s Sky"> No Man’s Sky</a> </p> <a href="https://publications.waset.org/abstracts/156533/the-chemistry-in-the-video-game-no-mans-sky" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156533.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">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">87</span> Analysis of Multilayer Neural Network Modeling and Long Short-Term Memory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Danilo%20L%C3%B3pez">Danilo López</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Vera"> Nelson Vera</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Pedraza"> Luis Pedraza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzes fundamental ideas and concepts related to neural networks, which provide the reader a theoretical explanation of Long Short-Term Memory (LSTM) networks operation classified as Deep Learning Systems, and to explicitly present the mathematical development of Backward Pass equations of the LSTM network model.

Social media can be used to share physically active lifestyles and possibly influence others to participate. In contrast, social media use may have adverse effects by decreasing participation in exercise. This study used a qualitative design to examine the relationship between social media use and exercise patterns. Participants were asked questions about their social media habits and how it might impact their physical activity behaviors. Self-reported exercise seemed to increase after viewing others engage in relatable activities or viewing someone that has overcame challenges. To increase the likelihood of engaging in exercise, exercise related posts should be low in difficulty, require few materials, or displayed progress from the individual posting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20media" title="social media">social media</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise" title=" exercise"> exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=adults" title=" adults"> adults</a> </p> <a href="https://publications.waset.org/abstracts/142278/social-media-use-and-exercise-behaviors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142278.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">265</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">85</span> Quality versus Excellence: The Importance of Employees Knowing the Difference</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chris%20Nelson">Chris Nelson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quality and excellence are qualitative topics that are usually addressed based on knowledge and past experience from leadership and those in charge of the organization. The significance of this study is to highlight the differences and similarities between these two mindsets and how an operational staff can most appropriately use them in the workplace. Quality and excellence are two words that are talked about a lot in the manufacturing world. Buzzwords such as operational excellence, quality controls, and efficiencies are discussed in the boardroom as well on the shop floor. These terms are used quite frequently and with good reasons. When a person visits their favorite local restaurant, They go because 1) they like the food and 2) the people are some of the greatest individuals to be around. With that in mind, they know they always put out quality food. They do not always go because the quality of the food is far superior than other restaurants. But the quality of ingredients always meets their expectations. When they compare them to the term excellence, they are disappointed. The food never looks like the pictures on the menu. But when have you ever been to a restaurant where the food looks the same as on the menu? For them, when evaluating which buzzword to use as a guiding star, its simple: excellence. The corporation can accomplish these goals by operating at a standard that far exceeds customer’s wants and needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20engineering" title="industrial engineering">industrial engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20and%20technology" title=" management and technology"> management and technology</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics%20and%20scheduling" title=" logistics and scheduling"> logistics and scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=six%20sigma" title=" six sigma"> six sigma</a> </p> <a href="https://publications.waset.org/abstracts/83580/quality-versus-excellence-the-importance-of-employees-knowing-the-difference" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83580.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">205</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">84</span> Fixed-Bed Column Studies of Green Malachite Removal by Use of Alginate-Encapsulated Aluminium Pillared Clay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lazhar%20mouloud">Lazhar mouloud</a>, <a href="https://publications.waset.org/abstracts/search?q=Chemat%20Zoubida"> Chemat Zoubida</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouhoumna%20Faiza"> Ouhoumna Faiza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study, concerns the modeling of breakthrough curves obtained in the adsorption column of malachite green into alginate-encapsulated aluminium pillared clay in fixed bed according to various operating parameters such as the initial concentration, the feed rate and the height fixed bed, applying mathematical models namely: the model of Bohart and Adams, Wolborska, Bed Depth Service Time, Clark and Yoon-Nelson.

The most important contribution of this theory to the field of English Language Teaching (ELT) is its role in identifying individual differences and designing more learner-centered programs. The present study aims at investigating the relationship between different elements of multiple intelligence and grammar scores. To this end, 63 female Iranian EFL learner selected from among intermediate students participated in the study. The instruments employed were a Nelson English language test, Michigan Grammar Test, and Teele Inventory for Multiple Intelligences (TIMI). The results of Pearson Product-Moment Correlation revealed a significant positive correlation between grammatical accuracy and linguistic as well as interpersonal intelligence.

The challenge in professional peace officer education is that there is a vast range of defining de-escalation and understanding the various techniques involved, many of which are based on popular media. This research surveyed professional peace officer education university students on their definition of de-escalation and the techniques associated with de-escalation before specific communications coursework was completed. The students were then surveyed after the communication coursework was completed to determine the changes in defining and understanding de-escalation techniques. This research has found that clearly defining de-escalation and emphasizing the broad range of techniques available enhances the students’ understanding and application of proper de-escalation. This research demonstrates the need for professional peace officer education to move students from media concepts of law enforcement to theoretical concepts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criminal%20justice%20education" title="criminal justice education">criminal justice education</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20theory" title=" communication theory"> communication theory</a>, <a href="https://publications.waset.org/abstracts/search?q=de-escalation" title=" de-escalation"> de-escalation</a>, <a href="https://publications.waset.org/abstracts/search?q=peace%20officer%20communication" title=" peace officer communication"> peace officer communication</a> </p> <a href="https://publications.waset.org/abstracts/100518/changes-in-student-definition-of-de-escalation-in-professional-peace-officer-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100518.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">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Antimicrobial Potential of Calendula officinalis Extracts on Flavobacterium columnare of Clarias gariepinus Fingerlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Rotimi%20Osungbemiro">Nelson Rotimi Osungbemiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanni%20Rafiu%20Olugbenga"> Sanni Rafiu Olugbenga</a>, <a href="https://publications.waset.org/abstracts/search?q=Abayomi%20Olufemi%20Olajuyigbe"> Abayomi Olufemi Olajuyigbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ninety Fingerlings of Clarias gariepinus were exposed to the pathogenic Flavobacterium columnare a Gram Negative bacteria responsible for high mortality in fish pond raised young fish (fries and fingerlings) of Clarias sp. in Southwestern Nigeria.

T-test analysis also revealed that there was a marked significant difference between bacterial load in guts of sampled Clarias from fresh water and brackish water habitats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteria%20flora" title="bacteria flora">bacteria flora</a>, <a href="https://publications.waset.org/abstracts/search?q=gut" title=" gut"> gut</a>, <a href="https://publications.waset.org/abstracts/search?q=Clarias%20gariepinus" title=" Clarias gariepinus"> Clarias gariepinus</a>, <a href="https://publications.waset.org/abstracts/search?q=Owena%20river" title=" Owena river"> Owena river</a> </p> <a href="https://publications.waset.org/abstracts/6024/bacteria-flora-in-the-gut-and-respiratory-organs-of-clarias-gariepinus-in-fresh-and-brackish-water-habitats-of-ondo-state-southwest-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6024.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">461</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">77</span> Moderating Influence of Environmental Hostility and External Relational Capital on the Effect of Entrepreneurial Orientation on Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Ugbedeojo%20Nelson">Peter Ugbedeojo Nelson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the tremendous advancements and knowledge acquisition around entrepreneurship orientation (EO) research, there may still be more to learn on how environmental dynamics would permute organizational processes and determine the extent to which success would be achieved. Using the contingency theory, we test a model that proposes a moderating influence of external relational capital and environmental hostility on the EO-performance effect of 423 managers/owners of small and medium scale enterprises. The hypotheses were tested using Hayes simultaneous regression, and the results showed that all EO dimensions (risk-taking, innovation, and performance) had a main effect on performance while the moderating variables interacted well with risk-taking (more than other EO dimensions) to improve performance. However, external relational capital, more than environmental hostility, influences the EO-performance relationship. Our findings highlight the differential ways that EO dimensions interact with environmental contingencies to influence performance. Further studies can examine how competitive aggressiveness and autonomy are moderated by external relational capital and environmental hostility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=external%20relational%20capital" title="external relational capital">external relational capital</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20orientation" title=" entrepreneurial orientation"> entrepreneurial orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk-taking" title=" risk-taking"> risk-taking</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=proactiveness" title=" proactiveness"> proactiveness</a> </p> <a href="https://publications.waset.org/abstracts/185938/moderating-influence-of-environmental-hostility-and-external-relational-capital-on-the-effect-of-entrepreneurial-orientation-on-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185938.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">55</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">76</span> Political Leadership: Bane of African Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samaila%20Liman%20Gamba">Samaila Liman Gamba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discussed the importance of good governance and its impact on the socio-economic and political development of African countries and, conversely, its underdevelopment and consequent stagnation. The study employed the use of quantitative and descriptive methods of collecting secondary data. The system analysis approach was also adopted as the theoretical framework. It is a global system, but it is also used to analyze the place of regions and single states within it. The study showed that political leadership in Africa based on empirical observation and documented evidence since the hard-won political independence from colonial Europe has become one of Africa’s sources of problems confronting the states and their resources became the primary purpose of political contestation and the establishment of a political culture based on ethnicity and authoritarian pattern of governance. The solution is for African leaders to learn and imbibe the leadership qualities of the late Nelson Mandela, Nyerere and Kwame Nkrumah, who carried their citizens along and were devoid of ethnicity and personal aggrandizement. They sacrificed their lives for their countrymen and fought against imperialism and are counted as patriots. <p class="card-text"><strong>Keywords:</strong> <a
