The aim of this study was to directly interrogate healthcare workers involved in TB control on what they consider to be the drivers of the TB epidemic in Angola. Methods: Twenty four in-depth qualitative interviews were conducted with medical staff working in this field in the provinces of Luanda and Benguela. Results: The healthcare professionals see the migrant working poor as a particular problem for the control of TB. These migrants are constructed as ‘Rural People’ and are seen as non-compliant and late-presenting. This is a stigmatized and marginal group contending with the additional stigma associated with TB infection. The healthcare professionals interviewed also see the interruption of treatment and self medication generally as a better explanation for the TB epidemic than urbanization or lack of medication. Conclusions: The local narrative is in contrast to previous explanations used elsewhere in the developing world. To be effective policy must recognize the local issues of the migrant workforce, interruption of treatment and the stigma associated with TB in Angola. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Africa" title="Africa">Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=Angola" title=" Angola"> Angola</a>, <a href="https://publications.waset.org/abstracts/search?q=migrants" title=" migrants"> migrants</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative" title=" qualitative"> qualitative</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/91528/challenges-to-tuberculosis-control-in-angola-the-narrative-of-medical-professionals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91528.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">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Organizational Commitment and Job Satisfaction among Health Professionals of a Maternity Ward in Lubango, Angola</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Vueba">Maria Vueba</a>, <a href="https://publications.waset.org/abstracts/search?q=Tchilissila%20A.%20Simoes"> Tchilissila A.

Working in these health facilities may be of great challenge for health professionals. In this study, we aimed to identify the presence of occupational stress in 76 nurses working in a maternity ward in Lubango, Southern Angola. The participants completed the Health Professional Stress Questionnaire and reported a moderate and high level of stress. To these individuals, 'receiving a low salary,' 'inadequate/insufficient salary,' 'overwork or very demanding work' and 'working long hours in a row' seemed to be the main indicators of occupational stress. Moreover, there was an influence of the work overload, the remuneration earned, the career, and family conflicts in the occupational stress index. These results contributed to a better understanding of the difficulties Angolan nurses are facing and the need to implement policies that envisage the wellbeing of this population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Africa" title="Africa">Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=maternity%20wards" title=" maternity wards"> maternity wards</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20stress" title=" occupational stress "> occupational stress </a> </p> <a href="https://publications.waset.org/abstracts/126805/occupational-stress-in-nurses-of-a-maternity-ward-in-lubango-angola" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126805.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">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> A Path for Assistance for People With Stroke in Angola</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Louren%C3%A7o%20Jos%C3%A9">Lourenço José</a>, <a href="https://publications.waset.org/abstracts/search?q=Elsa%20Melo"> Elsa Melo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Viera"> Sandra Viera</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Pinheiro"> Ana Pinheiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: People with stroke in Angola face challenges in accessing appropriate healthcare and rehabilitation services.

In this study, we aimed to assess the index of self-concept and self-esteem of adolescents from private and public secondary schools in Lubango, Angola. One hundred adolescents, between 16 and 18 years old (M = 17.2 years, SD = 0.81), completed the Piers-Harris Children's Self-Concept Scale 2 (Piers, 1984) and the Self-Perception Profile for Children (SPPC; Harter, 1985). Our results pointed out lower values of self-esteem and self-concept compared to international samples. Moreover, the level of education and the type of school attended did not seem to influence the level of participants' self-concept and self-esteem. These results contributed to enrich the literature on Angolan adolescents and propels intervention programs to enhance the self-concept and self-esteem of these individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20adolescents" title="African adolescents">African adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=post-war%20societies" title=" post-war societies"> post-war societies</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem"> self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=self-concept" title=" self-concept"> self-concept</a> </p> <a href="https://publications.waset.org/abstracts/126804/self-concept-and-self-esteem-of-adolescents-in-lubango-angola-an-exploratory-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126804.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">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Profile and Care of Stroke Patients in Angola: Preliminary Results of a Longitudinal Two-Center Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Jos%C3%A9">L.

Methods: A prospective longitudinal study was conducted at two Health centers, from March to November 2023, enrolling stroke patients. Data was gathered using a survey created by the researchers and validated by a health panel of experts from Angola. The analysis focused on demographic and stroke characteristics, as well as the care provided. Ethical approval and informed consent were obtained. Results: Preliminary results of a total of 186 patients are described, 122 from a Central Acute Care Hospital, with a mean age of 51.3±14.35 years old, a BMI of 26.7±4.15 kg/m2, 41% male, and 64 patients from a Rehabilitation Center, with 55.6±11.55 years old, a BMI of 27.0±3.8 kg/m2, 53% male. Ischemic stroke was reported as the most representative type in both centers (71.3% and 70.3%, respectively), though 100% of patients had no imaging diagnosis confirmation, neither data about the subtype was given. For patients admitted to the Hospital, discharge occurred before rehabilitation, and no follow-up was possible. No rehabilitation care was delivered in the first 7 days after the stroke. In the Rehabilitation Center, patient’s rehabilitation started in the late subacute phase, after a mean of 171.8±11.5 days. Conclusions: Stroke diagnosis lacks imaging confirmation, which is decisive for proper treatment, and rehabilitation starts during the late subacute phase, which is too late considering the international guidelines and the best window of opportunity for neuroplasticity and recovery. These results highlight the urgent need for the definition of Stroke-directed Health Care Policies in Angola. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stroke" title="stroke">stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=personalized%20health%20care" title=" personalized health care"> personalized health care</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20recovery" title=" functional recovery"> functional recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20policies" title=" health policies"> health policies</a> </p> <a href="https://publications.waset.org/abstracts/188490/profile-and-care-of-stroke-patients-in-angola-preliminary-results-of-a-longitudinal-two-center-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188490.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">24</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> The Challenge of Characterising Drought Risk in Data Scarce Regions: The Case of the South of Angola</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Limones">Natalia Limones</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Marzo"> Javier Marzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Wijnen"> Marcus Wijnen</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleix%20Serrat-Capdevila"> Aleix Serrat-Capdevila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research we developed a structured approach for the detection of areas under the highest levels of drought risk that is suitable for data-scarce environments. The methodology is based on recent scientific outcomes and methods and can be easily adapted to different contexts in successive exercises. The research reviews the history of drought in the south of Angola and characterizes the experienced hazard in the episode from 2012, focusing on the meteorological and the hydrological drought types. Only global open data information coming from modeling or remote sensing was used for the description of the hydroclimatological variables since there is almost no ground data in this part of the country. Also, the study intends to portray the socioeconomic vulnerabilities and the exposure to the phenomenon in the region to fully understand the risk. As a result, a map of the areas under the highest risk in the south of the country is produced, which is one of the main outputs of this work. It was also possible to confirm that the set of indicators used revealed different drought vulnerability profiles in the South of Angola and, as a result, several varieties of priority areas prone to distinctive impacts were recognized. The results demonstrated that most of the region experienced a severe multi-year meteorological drought that triggered an unprecedent exhaustion of the surface water resources, and that the majority of their socioeconomic impacts started soon after the identified onset of these processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought%20risk" title="drought risk">drought risk</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure" title=" exposure"> exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard" title=" hazard"> hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/138085/the-challenge-of-characterising-drought-risk-in-data-scarce-regions-the-case-of-the-south-of-angola" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138085.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">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> The First Import of Yellow Fever Cases in China and Its Revealing Suggestions for the Control and Prevention of Imported Emerging Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chao%20Li">Chao Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Zhou"> Lei Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruiqi%20Ren"> Ruiqi Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Dan%20Li"> Dan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yali%20Wang"> Yali Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Daxin%20Ni"> Daxin Ni</a>, <a href="https://publications.waset.org/abstracts/search?q=Zijian%20Feng"> Zijian Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Qun%20Li"> Qun Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In 2016, yellow fever had been first ever discovered in China, soon after the yellow fever epidemic occurred in Angola. After the discovery, China had promptly made the national protocol of control and prevention and strengthened the surveillance on passenger and vector. In this study, a descriptive analysis was conducted to summarize China’s experiences of response towards this import epidemic, in the hope of providing experiences on prevention and control of yellow fever and other similar imported infectious diseases in the future. Methods: The imported cases were discovered and reported by General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) and several hospitals. Each clinically diagnosed yellow fever case was confirmed by real-time reverse transcriptase polymerase chain reaction (RT–PCR). The data of the imported yellow fever cases were collected by local Centers for Disease Control and Prevention (CDC) through field investigations soon after they received the reports. Results: A total of 11 imported cases from Angola were reported in China, during Angola’s yellow fever outbreak. Six cases were discovered by the AQSIQ, among which two with mild symptom were initiative declarations at the time of entry. Except for one death, the remaining 10 cases all had recovered after timely and proper treatment. All cases are Chinese, and lived in Luanda, the capital of Angola. 73% were retailers (8/11) from Fuqing city in Fujian province, and the other three were labors send by companies. 10 cases had experiences of medical treatment in Luanda after onset, among which 8 cases visited the same local Chinese medicine hospital (China Railway four Bureau Hospital). Among the 11 cases, only one case had an effective vaccination. The result of emergency surveillance for mosquito density showed that only 14 containers of water were found positive around places of three cases, and the Breteau Index is 15. Conclusions: Effective response was taken to control and prevent the outbreak of yellow fever in China after discovering the imported cases. However, though the similar origin of Chinese in Angola has provided an easy access for disease detection, information sharing, health education and vaccination on yellow fever; these conveniences were overlooked during previous disease prevention methods. Besides, only one case having effective vaccination revealed the inadequate capacity of immunization service in China. These findings will provide suggestions to improve China’s capacity to deal with not only yellow fever but also other similar imported diseases in China. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=yellow%20fever" title="yellow fever">yellow fever</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20import" title=" first import"> first import</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a>, <a href="https://publications.waset.org/abstracts/search?q=suggestion" title=" suggestion"> suggestion</a> </p> <a href="https://publications.waset.org/abstracts/85916/the-first-import-of-yellow-fever-cases-in-china-and-its-revealing-suggestions-for-the-control-and-prevention-of-imported-emerging-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85916.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">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Translating History in a Brazilian Graphic Novel: A Translation Project for Angola Janga by Marcelo D'Salete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Rezende">Carolina Rezende</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Cesar%20Neves%20Monteiro"> Julio Cesar Neves Monteiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditionally, History and fiction are considered to be opposing fields of study. While one is linked to the study of facts, things that have happened within the limits of ‘reality’, the other explores a made-up world, originated from imagination and fantasy. However, despite their apparent discrepancies, there is a fundamental trait that brings them closer. Historical narratives, similarly to fiction ones, are produced based on multiple interpretations of an event, which are transmitted in a rather subjective way by language. It is within this perspective of history and fiction intertwined that this paper aims to discuss the translation of historical facts in the graphic novel Angola Janga, by Marcelo D’Salete, as well as presenting it as a historical document. The novel, which is divided into 11 short stories, narrates the rebellions that took place in Serra da Barriga, between the 16th and 17th centuries, that resulted in the Guerra dos Palmares. The graphic novel in question is a result of the author’s 11-year historical and bibliographical research, which combines history and fiction in order to shed a light of the confrontation that history seems to overlook. Also, the book includes a foreword, glossary, chronological line of Guerra dos Palmares, as well as maps and references used by the author during his research. For that, a few segments from the book will be selected and translated in order to show such connection between history and fiction, and the discussion resulted from it will be based on the works of Southgate (2009), Pym (2001) and D’hulst (2001). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphic%20novel" title="graphic novel">graphic novel</a>, <a href="https://publications.waset.org/abstracts/search?q=history" title=" history"> history</a>, <a href="https://publications.waset.org/abstracts/search?q=fiction" title=" fiction"> fiction</a>, <a href="https://publications.waset.org/abstracts/search?q=Palmares" title=" Palmares"> Palmares</a> </p> <a href="https://publications.waset.org/abstracts/100900/translating-history-in-a-brazilian-graphic-novel-a-translation-project-for-angola-janga-by-marcelo-dsalete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100900.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">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Solving Extended Linear Complementarity Problems (XLCP) - Wood and Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liberto%20Pombal">Liberto Pombal</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Dieter%20Jaekel"> Christian Dieter Jaekel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is to establish theoretical and numerical conditions for Solving Extended Linear Complementarity Problems (XLCP), with emphasis on the Horizontal Linear Complementarity Problem (HLCP).

This paper develops research on low-cost housing models for developing countries and what is the best method to embed overcrowding as an important parameter for adaptability. A critical review of international overcrowding indicators and their application in two developing countries, Cape Verde and Angola, is presented. The several rationales and the constraints for an accurate assessment of overcrowding are considered, namely baseline data (statistics), which can induce misjudgments, as well as social and cultural factors (such as personal choices of residents). This paper proposes a way to tackle overcrowding through housing adaptability, considering factors such as physical flexibility, functional ambiguity, and incremental expansion schemes. Moreover, a case-study is presented to establish a framework for the theoretical application of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20housing" title="adaptive housing">adaptive housing</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cost%20housing" title=" low cost housing"> low cost housing</a>, <a href="https://publications.waset.org/abstracts/search?q=overcrowding" title=" overcrowding"> overcrowding</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20model" title=" housing model"> housing model</a> </p> <a href="https://publications.waset.org/abstracts/86914/overcrowding-and-adequate-housing-the-potential-of-adaptability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86914.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">191</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">8</span> Child Mortality in Portuguese Speaking Africa Countries: Levels and Trends, 1975-2021</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alcino%20Panguana">Alcino Panguana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All Portuguese-speaking African countries are in Sub-Saharan Africa, a region that has high infant mortality rates, being responsible for 49.6% of deaths in Portuguese-speaking African countries, Angola has levels of infant mortality among children, where 2017, 156 children who died before reaching 1 year of life in 1000 live births.

Mostly, they are in developing countries with the situation in Sub-Saharan Africa, the abduction and employment of children as soldiers is a form of exploitative labour that is tantamount to slavery. Since the end of cold war, Child soldier has increased in Africa countries like Angola, Liberia, Sierra Leone and Uganda. This study examines the main cause of the recruitment and use of child soldiers and its challenges to human right. It further assesses the role of international regional bodies and various governments in curbing child soldiers with a view to proffer suggestions on how to address some of the resultant threat of human right. The study posits that the control of small arms and light weapons is essential in curtailing the spread of child soldier and abuse of human right. This hopefully should result in the sustainability of human/child right in African continent. It is a recommendation of this study that, in order to sustain human right in the region, all Africa leaders, government and regional bodies; such as African Union, Economic Community of West African States, South African Development Community among others, should cooperate and work together to address the issue of illicit small arms, which could eventually lead to child soldier. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arms%20control" title="arms control">arms control</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20soldier" title=" child soldier"> child soldier</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20right" title=" human right"> human right</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20arms" title=" small arms"> small arms</a> </p> <a href="https://publications.waset.org/abstracts/72721/child-soldier-in-africa-a-big-challenge-to-human-right" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72721.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">207</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">6</span> Connecting African Ubuntu and Social Work Practices for Human Rights: The Value of Dignity and Worth of a Person</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meinrad%20Haule%20Lembuka">Meinrad Haule Lembuka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social work profession one of its primary mission is to restore and maintain human rights where social workers recognise all humanity as equal, and so too the philosophies that have developed across the world’s regions. Ubuntu means African Humanism, where realization of human rights has been a primary role for every member of community to protect other member. Before Universal declaration of human rights, African societies had a long history of embracing human rights through Ubuntu approach model. The article used Ubuntu theory to guide the review process of existing literature since Ubuntu theory since is grounded in African cultural values and ecology, and it was thought that application of Ubuntu theory was relevant to reflect reality of Ubuntu model and indigenization of social work in African context. Results have shown that in realization of human rights, Ubuntu was practiced is termed as model, philosophy, cultural values, way of life or framework originated in sub-sahara Africa and some of remarkably practice model in several African communities such as Angola, (gimuntu), Botswana (muthu), Burkina Faso (maaya), Ghana (biako ye), Malawi (umunthu), Mali (maaya/hadama de ya), Namibia (omundu), Nigeria (mutunchi/iwa/agwa), (bantu), Sierra Leonne (maaya), South Africa (ubuntu/botho) and Tanzania (utu/obuntu/bumuntu). Collective and holistic mechanism of Ubuntu is found through an Ubuntu framework that is contributed by individual, family, community and spirit that is characterised by interconnectedness of all things and beings. Each society has its own name but the practice remained the same and realization of human rights in Africa context was centred through human dignity, Ubuntu is built under cultural values of humanism that brings implications for African social worker to integrate this indigenous model into social work practice in restoring and maintain human rights. Social workers should promote policies and practices that demonstrate respect for human life, difference, support and expansion of cultural knowledge and resources, advocate for programmes and institutions that demonstrate cultural competence and promote policies that safeguard the rights and confirm equity and social justice for all people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20ubuntu" title="African ubuntu">African ubuntu</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous%20practice" title=" indigenous practice"> indigenous practice</a>, <a href="https://publications.waset.org/abstracts/search?q=African%20humanism" title=" African humanism"> African humanism</a>, <a href="https://publications.waset.org/abstracts/search?q=African%20human%20rights" title=" African human rights"> African human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20work%20and%20human%20rights" title=" social work and human rights"> social work and human rights</a> </p> <a href="https://publications.waset.org/abstracts/173296/connecting-african-ubuntu-and-social-work-practices-for-human-rights-the-value-of-dignity-and-worth-of-a-person" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173296.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">71</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">5</span> Experimental Activity on the Photovoltaic Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salom%C3%A3o%20Manuel%20Francisco">Salomão Manuel Francisco</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Ant%C3%B3nio%20Salgueiro%20Da%20Silva"> Manuel António Salgueiro Da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Bento%20Filipe%20Barreiras%20Pinto%20Cavadas"> Bento Filipe Barreiras Pinto Cavadas</a>, <a href="https://publications.waset.org/abstracts/search?q=Teresa%20Monteiro%20Seixas"> Teresa Monteiro Seixas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In bachelor's degrees in Physics Education framework in Angola, and to a certain extent, within the community of Portuguese language countries (CPLP), teaching methodologies rely heavily on theoretical memorization and mathematical demonstrations. This approach often discourages students, particularly the female population, as the reliance on theoretical mathematical demonstrations generates the perception of Physics as an arduous, challenging discipline. To address this challenge and recognize the value of practical application as an evaluative criterion of material truth, we propose a practical activity in Environmental Physics that will be shared with Angolan higher education teachers, who will receive full scaffolding and support from the authors. These teachers, adopting and developing similar activities in a classroom setting, will contribute to the environmental education framework as well. Additionally, this work aligns with different goals of UNESCO's 2030 agenda, namely, specifically, goals 4, 5, 7, 11, 13, and 17. The experimental activity developed in this work is centered around the demonstration of the photovoltaic effect and its application for renewable energy production. The first objective of the activity is to study the variation of electrical power supplied by a photovoltaic system (PV) to an electrical circuit as the angle of light incidence changes. Students can observe that the power supplied to the circuit is greater when light rays fall perpendicularly on the PV. However, as the angle of incidence increases, resulting in a larger area covered by the light rays, the power supplied to the circuit decreases due to lower irradiance. The second objective is to demonstrate that the power output can be maximized by adjusting the circuit load resistance at each irradiance value. In these two parts of the activity, students can analyze experimental data taking into account the irradiance law and the equivalent circuit description of a PV cell. Through detailed data analysis, students are also expected to assess the effects of temperature on PV efficiency degradation and the efficiency enhancement provided by light concentration mechanisms. As a third objective, students can explore how the color of incident light affects the PV output power, considering the quantum nature of light and its interaction with the PV system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experiments" title="experiments">experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiation%20law" title=" irradiation law"> irradiation law</a>, <a href="https://publications.waset.org/abstracts/search?q=physic%20teaching" title=" physic teaching"> physic teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20effect" title=" photovoltaic effect"> photovoltaic effect</a> </p> <a href="https://publications.waset.org/abstracts/168923/experimental-activity-on-the-photovoltaic-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168923.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">83</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">4</span> On Panel Data Analysis of Factors on Economic Advances in Some African Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayoola%20Femi%20J.">Ayoola Femi J.</a>, <a href="https://publications.waset.org/abstracts/search?q=Kayode%20Balogun"> Kayode Balogun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In some African Countries, increase in Gross Domestic Products (GDP) has not translated to real development as expected by common-man in his household. For decades, a lot of contests on economic growth and development has been a nagging issues. The focus of this study is to analysing the effects of economic determinants/factors on economic advances in some African Countries by employing panel data analysis. The yearly (1990-2013) data were obtained from the world economic outlook database of the International Monetary Fund (IMF), for probing the effects of these variables on growth rate in some selected African countries which include: Nigeria, Algeria, Angola, Benin, Botswana, Burundi, Cape-Verde, Cameroun, Central African Republic, Chad, Republic Of Congo, Cote di’ Voire, Egypt, Equatorial-Guinea, Ethiopia, Gabon, Ghana, Guinea Bissau, Kenya, Lesotho, Madagascar, Mali, Mauritius, Morocco, Mozambique, Niger, Rwanda, Senegal, Seychelles, Sierra Leone, South Africa, Sudan, Swaziland, Tanzania, Togo, Tunisia, and Uganda. The effects of 6 macroeconomic variables on GDP were critically examined. We used 37 Countries GDP as our dependent variable and 6 independent variables used in this study include: Total Investment (totinv), Inflation (inf), Population (popl), current account balance (cab), volume of imports of goods and services (vimgs), and volume of exports of goods and services (vexgs). The results of our analysis shows that total investment, population and volume of exports of goods and services strongly affect the economic growth. We noticed that population of these selected countries positively affect the GDP while total investment and volume of exports negatively affect GDP. On the contrary, inflation, current account balance and volume of imports of goods and services’ contribution to the GDP are insignificant.

We noticed that population of these selected countries positively affect the GDP while total investment and volume of exports negatively affect GDP. On the contrary, inflation, current account balance and volume of imports of goods and services’ contribution to the GDP are insignificant. The results of this study would be useful for individual African governments for developing a suitable and appropriate economic policies and strategies. It will also help investors to understand the economic nature and viability of Africa as a continent as well as its individual countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20countries" title="African countries">African countries</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth%20and%20development" title=" economic growth and development"> economic growth and development</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20domestic%20products" title=" gross domestic products"> gross domestic products</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20panel%20data%20models" title=" static panel data models "> static panel data models </a> </p> <a href="https://publications.waset.org/abstracts/26964/on-panel-data-analysis-of-factors-on-economic-advances-in-some-african-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26964.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">475</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">3</span> Evaluation of Yield and Yield Components of Malaysian Palm Oil Board-Senegal Oil Palm Germplasm Using Multivariate Tools </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khin%20Aye%20Myint">Khin Aye Myint</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Rafii%20Yusop"> Mohd Rafii Yusop</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Yusoff%20Abd%20Samad"> Mohd Yusoff Abd Samad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shairul%20Izan%20Ramlee"> Shairul Izan Ramlee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Din%20Amiruddin"> Mohd Din Amiruddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulkifli%20Yaakub"> Zulkifli Yaakub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The narrow base of genetic is the main obstacle of breeding and genetic improvement in oil palm industry. In order to broaden the genetic bases, the Malaysian Palm Oil Board has been extensively collected wild germplasm from its original area of 11 African countries which are Nigeria, Senegal, Gambia, Guinea, Sierra Leone, Ghana, Cameroon, Zaire, Angola, Madagascar, and Tanzania. The germplasm collections were established and maintained as a field gene bank in Malaysian Palm Oil Board (MPOB) Research Station in Kluang, Johor, Malaysia to conserve a wide range of oil palm genetic resources for genetic improvement of Malaysian oil palm industry. Therefore, assessing the performance and genetic diversity of the wild materials is very important for understanding the genetic structure of natural oil palm population and to explore genetic resources. Principal component analysis (PCA) and Cluster analysis are very efficient multivariate tools in the evaluation of genetic variation of germplasm and have been applied in many crops. In this study, eight populations of MPOB-Senegal oil palm germplasm were studied to explore the genetic variation pattern using PCA and cluster analysis. A total of 20 yield and yield component traits were used to analyze PCA and Ward’s clustering using SAS 9.4 version software. The first four principal components which have eigenvalue >1 accounted for 93% of total variation with the value of 44%, 19%, 18% and 12% respectively for each principal component. PC1 showed highest positive correlation with fresh fruit bunch (0.315), bunch number (0.321), oil yield (0.317), kernel yield (0.326), total economic product (0.324), and total oil (0.324) while PC 2 has the largest positive association with oil to wet mesocarp (0.397) and oil to fruit (0.458). The oil palm population were grouped into four distinct clusters based on 20 evaluated traits, this imply that high genetic variation existed in among the germplasm. Cluster 1 contains two populations which are SEN 12 and SEN 10, while cluster 2 has only one population of SEN 3. Cluster 3 consists of three populations which are SEN 4, SEN 6, and SEN 7 while SEN 2 and SEN 5 were grouped in cluster 4. Cluster 4 showed the highest mean value of fresh fruit bunch, bunch number, oil yield, kernel yield, total economic product, and total oil and Cluster 1 was characterized by high oil to wet mesocarp, and oil to fruit. The desired traits that have the largest positive correlation on extracted PCs could be utilized for the improvement of oil palm breeding program. The populations from different clusters with the highest cluster means could be used for hybridization. The information from this study can be utilized for effective conservation and selection of the MPOB-Senegal oil palm germplasm for the future breeding program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cluster%20analysis" title="cluster analysis">cluster analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20variability" title=" genetic variability"> genetic variability</a>, <a href="https://publications.waset.org/abstracts/search?q=germplasm" title=" germplasm"> germplasm</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20palm" title=" oil palm"> oil palm</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a> </p> <a href="https://publications.waset.org/abstracts/98332/evaluation-of-yield-and-yield-components-of-malaysian-palm-oil-board-senegal-oil-palm-germplasm-using-multivariate-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98332.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">164</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">2</span> Metal Contaminants in River Water and Human Urine after an Episode of Major Pollution by Mining Wastes in the Kasai Province of DR Congo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Remy%20Mpulumba%20Badiambile">Remy Mpulumba Badiambile</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Musa%20Obadia"> Paul Musa Obadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Malick%20Useni%20Mutayo"> Malick Useni Mutayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeef%20Numbi%20Mukanya"> Jeef Numbi Mukanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Patient%20Nkulu%20Banza"> Patient Nkulu Banza</a>, <a href="https://publications.waset.org/abstracts/search?q=Tony%20Kayembe%20Kitenge"> Tony Kayembe Kitenge</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Smolders"> Erik Smolders</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Fran%C3%A7ois%20Picron"> Jean-François Picron</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Haufroid"> Vincent Haufroid</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9lestin%20Banza%20Lubaba%20Nkulu"> Célestin Banza Lubaba Nkulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Nemery"> Benoit Nemery</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In July 2021, the Tshikapa river became heavily polluted by mining wastes from a diamond mine in neighboring Angola, leading to massive killing of fish, as well as disease and even deaths among residents living along the Tshikapa and Kasai rivers, a major contributory of the Congo river. The exact nature of the pollutants was unknown. Methods: In a cross-sectional study conducted in the city of Tshikapa in August 2021, we enrolled by opportunistic sampling 65 residents (11 children < 16y) living alongside the polluted rivers and 65 control residents (5 children) living alongside a non-affected portion of the Kasai river (upstream from the Tshikapa-Kasai confluence). We administered a questionnaire and obtained spot urine samples for measurements of thiocyanate (a metabolite of cyanide) and 26 trace metals (by ICP-MS). Metals (and pH) were also measured in samples of river water. Results: Participants from both groups consumed river water. In the area affected by the pollution, most participants had eaten dead fish. Prevalences of reported health symptoms were higher in the exposed group than among controls: skin rashes (52% vs 0%), diarrhea (40% vs 8%), abdominal pain (8% vs 3%), nausea (3% vs 0%). In polluted water, concentrations [median (range)] were only higher for nickel [(2.2(1.4–3.5)µg/L] and uranium [78(71–91)ng/L] than in non-polluted water [0.8(0.6–1.9)µg/L; 9(7–19)ng/L]. In urine, concentrations [µg/g creatinine, median(IQR)] were significantly higher in the exposed group than in controls for lithium [19.5(12.4–27.3) vs 6.9(5.9–12.1)], thallium [0.41(0.31–0.57) vs 0.19(0.16–0.39)], and uranium [0.026(0.013–0.037)] vs 0.012(0.006–0.024)]. Other elements did not differ between the groups, but levels were higher than reference values for several metals (including manganese, cobalt, nickel, and lead). Urinary thiocyanate concentrations did not differ. Conclusion: This study, after an ecological disaster in the DRC, has documented contamination of river water by nickel and uranium and high urinary levels of some trace metals among affected riverine populations. However, the exact cause of the massive fish kill and disease among residents remains elusive. The capacity to rapidly investigate toxic pollution events must be increased in the area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20contaminants" title="metal contaminants">metal contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20water%20and%20human%20urine" title=" river water and human urine"> river water and human urine</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution%20by%20mining%20wastes" title=" pollution by mining wastes"> pollution by mining wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=DR%20Congo" title=" DR Congo"> DR Congo</a> </p> <a href="https://publications.waset.org/abstracts/155385/metal-contaminants-in-river-water-and-human-urine-after-an-episode-of-major-pollution-by-mining-wastes-in-the-kasai-province-of-dr-congo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155385.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">157</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">1</span> Climate Change and Economic Performance in Selected Oil-Producing African Countries: A Trend Analysis Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waheed%20O.%20Majekodunmi">Waheed O. Majekodunmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change is a real global phenomenon and an unquestionable threat to our quest for a healthy and livable planet. It is now regarded as potentially the most monumental environmental challenge people and the planet will be confronted with over the next centuries. Expectedly, climate change mitigation was one of the central themes of COP 28. Despite contributing the least to climate change, Africa is and remains the hardest hit by the negative consequences of climate change including poor growth performance. Currently, it is being hypothesized that the high level of vulnerability and exposure to climate-related disasters, low adaptive capacity against global warming and high mitigation costs of climate change across the continent could be linked to the recent abysmal economic performance of African countries, especially in oil-producing countries where greenhouse gas emissions, is potentially more prevalent. This paper examines the impact of climate change on the economic performance of selected oil-producing countries in Africa using evidence from Nigeria, Algeria and Angola. The objective of the study is to determine whether or not climate change influences the economic performance of oil-producing countries in Africa by examining the nexus between economic growth and climate-related variables. The study seeks to investigate the effect of climate change on the pace of economic growth in African oil-producing countries. To achieve the research objectives, this study utilizes a quantitative approach by using historical and current secondary data sets to determine the relationship between climate-related variables and economic growth variables in the selected countries. The study employed numbers, percentages, tables and trend graphs to explain the trends or common patterns between climate change, economic growth and determinants of economic growth: governance effectiveness, infrastructure, macroeconomic stability and regulatory efficiency. Results from the empirical analysis of data show that the trends of economic growth and climate-related variables in the selected oil-producing countries are in the opposite directions as the increasing share of renewable energy sources in total energy consumption and the reduction in greenhouse gas emissions per capita in the oil-producing countries did not translate to higher economic growth. Further findings show that annual surface temperatures in the selected countries do not share similar trends with the food imports ratio and GDP per capita annual growth rate suggesting that climate change does not impact significantly agricultural productivity and economic growth in oil-producing countries in Africa. Annual surface temperature was also found to not share a similar pattern with governance effectiveness, macroeconomic stability and regulatory efficiency reinforcing the claim that some economic growth variables are independent of climate change. The policy implication of this research is that oil-producing African countries need to focus more on improving the macroeconomic environment and streamlining governance and institutional processes to boost their economic performance before considering the adoption of climate change adaptation and mitigation strategies. <p class="card-text"><strong>Keywords:</strong> <a
