In high school, the same concept is taught as the ratio between the masses of two bodies of the same volume. This dichotomy of the concept of relative density between the two educational cycles, separately approached, induces initial representations that can constitute epistemological obstacles for its conceptualization and scientific understanding. This study proposes an interdisciplinary approach between chemistry, physics, and mathematics, combining “intuitive understanding” and “mathematical formalism”, with the aim of evolving intuitive perceptions toward a scientific understanding of the concept of relative density, based on the sorting of plastic waste. After establishing the conditions of buoyancy, immersion, and sinking, <br />this approach highlights the existence of several types of plastics and their relative density based selective sorting. This experimentation on the buoyancy of solutions on each other and of solids in solutions provides chemistry and physics teachers with an experimental didactic tool to support their interventions in the teaching/learning process of the concept of relative density.

In high school, the same concept is taught as the ratio between the masses of two bodies of the same volume. This dichotomy of the concept of relative density between the two educational cycles, separately approached, induces initial representations that can constitute epistemological obstacles for its conceptualization and scientific understanding. This study proposes an interdisciplinary approach between chemistry, physics, and mathematics, combining “intuitive understanding” and “mathematical formalism”, with the aim of evolving intuitive perceptions toward a scientific understanding of the concept of relative density, based on the sorting of plastic waste. After establishing the conditions of buoyancy, immersion, and sinking,\r\nthis approach highlights the existence of several types of plastics and their relative density based selective sorting. This experimentation on the buoyancy of solutions on each other and of solids in solutions provides chemistry and physics teachers with an experimental didactic tool to support their interventions in the teaching/learning process of the concept of relative density.

S’inspirant du modèle REDOC, un schéma\r\nméthodologique a été proposé pour étayer les interventions des enseignants lors d’une\r\nsensibilisation de leurs élèves sur la notion de « déchet ».","publication":"Collection Pluraxes/Monde","publication_with_fallback":"Collection Pluraxes/Monde","downloadable_attachments":[{"id":110742026,"asset_id":113901096,"asset_type":"Work","always_allow_download":false,"scribd_thumbnail_url":"https://attachments.academia-assets.com/110742026/thumbnails/1.jpg","download_url":"https://d1wqtxts1xzle7.cloudfront.net/110742026/Evaluation_des_preconceptions_des_eleves-libre.pdf?1705982639=\u0026response-content-disposition=attachment%3B+filename%3DEvaluation_des_preconceptions_liees_a_l.pdf\u0026Expires=1732505937\u0026Signature=At3G90FdrTuJAMMHNK4HRXAI-GWq1zMs6iOrTljSVNNLYtVV~VUwdfYr35bC1dNSHMhlZC4va4-Kipsy8Y-KRDwN3-GO7wDffxl3th6T4icTP40NHBD1wwVd56--qj25yA9YdZhre2CAOdReYe3sM3d8nuYxnygLQ~J8lgkoir58tx4x3icpOb~-Bz~rlTe3vrhecD50HbXCzlAdrk77RYkbbB87M~cfO7T1fu~FN9Ib2u7VopcQ0lo5JO3ktAnDJht3ILbPujHeyD1sMxMRzveSD0pD7wNtcrQxZ1m-LnL1XCsgRPs0NnHnFCbgPOYt2JOWtPwUglVmXmgxc-nCWg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","download_file_url":"https://www.academia.edu/attachments/110742026/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&","full_thumbnail_url":"https://0.academia-photos.com/attachment_thumbnails/110742026/mini_magick20240123-1-f17h3r.png?1705982261"}],"downloadable_attachments_with_full_thumbnails":[{"id":110742026,"asset_id":113901096,"asset_type":"Work","always_allow_download":false,"scribd_thumbnail_url":"https://attachments.academia-assets.com/110742026/thumbnails/1.jpg","download_url":"https://d1wqtxts1xzle7.cloudfront.net/110742026/Evaluation_des_preconceptions_des_eleves-libre.pdf?1705982639=\u0026response-content-disposition=attachment%3B+filename%3DEvaluation_des_preconceptions_liees_a_l.pdf\u0026Expires=1732505937\u0026Signature=At3G90FdrTuJAMMHNK4HRXAI-GWq1zMs6iOrTljSVNNLYtVV~VUwdfYr35bC1dNSHMhlZC4va4-Kipsy8Y-KRDwN3-GO7wDffxl3th6T4icTP40NHBD1wwVd56--qj25yA9YdZhre2CAOdReYe3sM3d8nuYxnygLQ~J8lgkoir58tx4x3icpOb~-Bz~rlTe3vrhecD50HbXCzlAdrk77RYkbbB87M~cfO7T1fu~FN9Ib2u7VopcQ0lo5JO3ktAnDJht3ILbPujHeyD1sMxMRzveSD0pD7wNtcrQxZ1m-LnL1XCsgRPs0NnHnFCbgPOYt2JOWtPwUglVmXmgxc-nCWg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","download_file_url":"https://www.academia.edu/attachments/110742026/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&","full_thumbnail_url":"https://0.academia-photos.com/attachment_thumbnails/110742026/mini_magick20240123-1-f17h3r.png?1705982261"}],"has_pdf":true,"has_fulltext":true,"page_count":28,"ordered_authors":[{"id":199802241,"first_name":"Issa","last_name":"ZONGO","domain_name":"ens","page_name":"IssaZONGO","display_name":"Issa ZONGO","profile_url":"https://ens.academia.edu/IssaZONGO","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":1260605,"name":"ENVIRONNEMENT","url":"https://www.academia.edu/Documents/in/ENVIRONNEMENT","nofollow":false},{"id":4457790,"name":"Représentation initiale","url":"https://www.academia.edu/Documents/in/Repr%C3%A9sentation_initiale","nofollow":false},{"id":4457791,"name":"Déchet","url":"https://www.academia.edu/Documents/in/D%C3%A9chet"},{"id":4457792,"name":"modèle REDOC","url":"https://www.academia.edu/Documents/in/mod%C3%A8le_REDOC"}],"publication_year":2024,"publication_year_with_fallback":2024,"paper_rank":null,"all_time_views":44,"active_discussion":{}}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_113901151" data-work_id="113901151" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/113901151/Un_mod%C3%A8le_pr%C3%A9curseur_pour_%C3%A9tayer_l_enseignement_de_la_couleur_des_objets_en_optique_par_la_d%C3%A9marche_d_investigation">Un modèle précurseur pour étayer l’enseignement de la couleur des objets en optique par la démarche d’investigation</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">L'enseignement de l'optique se heurte à des représentations initiales chez les élèves liées à la familiarité de l'objet d'étude qu'est la lumière.

Cet article s'interroge sur l'impact d'un modèle précurseur sur la situation de départ d'une démarche d'investigation lors d'une séquence d'apprentissage en optique au collège. Partant d'un questionnaire sur l'ombre, la lumière transmise et la couleur des objets, l'étude a consisté à identifier d'abord quelques représentations initiales des élèves en optique. Á partir d'une analyse de séances de cours suivies d'entretiens de type auto-confrontation fondée sur la théorie de l'activité, elle a ensuite permis d'apprécier particulièrement les situations de départ élaborées par les enseignants. Cette analyse comparative de séances de cours sur la couleur des objets en classe de 3ème montre enfin que l'utilisation d'un modèle précurseur semble contribuer à l'élaboration d'une situation de départ concourant à la mise en œuvre efficace de la démarche d'investigation.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/113901151" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="526e8a8de240899ca66a40c2f8d1df13" rel="nofollow" data-download="{"attachment_id":110742079,"asset_id":113901151,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/110742079/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="199802241" href="https://ens.academia.edu/IssaZONGO">Issa ZONGO</a><script data-card-contents-for-user="199802241" type="text/json">{"id":199802241,"first_name":"Issa","last_name":"ZONGO","domain_name":"ens","page_name":"IssaZONGO","display_name":"Issa ZONGO","profile_url":"https://ens.academia.edu/IssaZONGO","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_113901151 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="113901151"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 113901151, container: ".js-paper-rank-work_113901151", }); });</script></li><li class="js-percentile-work_113901151 InlineList-item InlineList-item--bordered hidden u-tcGrayDark"><span class="percentile-widget hidden"><span class="u-mr2x percentile-widget" style="display: none">•</span><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 113901151; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-percentile-work_113901151"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></li><li class="js-view-count-work_113901151 InlineList-item InlineList-item--bordered hidden"><div><span><span class="js-view-count view-count u-mr2x" data-work-id="113901151"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113901151; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=113901151]").text(description); $(".js-view-count-work_113901151").attr('title', description).tooltip(); }); });</script></span><script>$(function() { $(".js-view-count-work_113901151").removeClass('hidden') })</script></div></li></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_114849286" data-work_id="114849286" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/114849286/%C3%89ducation_environnementale_impl%C3%A9mentation_du_tri_des_d%C3%A9chets_plastiques_en_classe_de_premi%C3%A8re_au_Burkina_Faso">Éducation environnementale : implémentation du tri des déchets plastiques en classe de première au Burkina Faso</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Cet article analyse la dynamique de développement des pratiques d'enseignement écocitoyennes liées à l'éducation environnementale.

Ces séquences constituent, en chimie, des opportunités de sensibilisations de l'enseignant et de l'apprenant, au tri à la source des déchets plastiques en fonction de leur constitution.","publication":"Revue LES TISONS, Revue internationale des Sciences de l'Homme et de la Société (RISHS)","publication_with_fallback":"Revue LES TISONS, Revue internationale des Sciences de l'Homme et de la Société (RISHS)","downloadable_attachments":[{"id":111430309,"asset_id":114849286,"asset_type":"Work","always_allow_download":false,"scribd_thumbnail_url":"https://attachments.academia-assets.com/111430309/thumbnails/1.jpg","download_url":"https://d1wqtxts1xzle7.cloudfront.net/111430309/Education_environnementale_ISSA_ZONGO-libre.pdf?1707841103=\u0026response-content-disposition=attachment%3B+filename%3DEducation_environnementale_implementatio.pdf\u0026Expires=1732505937\u0026Signature=VLwgmr1Qb0rTaIvWs82dRKZ-KPwpv1rBWXAIbrnFudYhB4E8l5RcFaOMQsz27MhTni7PzY4o7MEj6tswcrK51ezTTDi5Zxb7xJdcwhrzR00fT6BRD4lv0ZSniWYpDDkTsfauHX3FS3Rxc-KsW-98eZgUOId8qYaJCGGcVgeS6ltUNu~tdUNU5HdC2gGWIzS4Yooos1ekdQ~DM-LR5Vm5hDoWqsOgN3vrQD0eDBRu7n~WzRdPwnyEgpExwo8EjPsmMWDUwv60awH1IUMRrFXoDKr8qqfWjO0YSUwH-ykMl4chqCxnAKf0el8fCKHfX7S2qs8X7hI-cVK3XLnXlYuHhg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","download_file_url":"https://www.academia.edu/attachments/111430309/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&","full_thumbnail_url":"https://0.academia-photos.com/attachment_thumbnails/111430309/mini_magick20240213-1-wgndqh.png?1707829712"}],"downloadable_attachments_with_full_thumbnails":[{"id":111430309,"asset_id":114849286,"asset_type":"Work","always_allow_download":false,"scribd_thumbnail_url":"https://attachments.academia-assets.com/111430309/thumbnails/1.jpg","download_url":"https://d1wqtxts1xzle7.cloudfront.net/111430309/Education_environnementale_ISSA_ZONGO-libre.pdf?1707841103=\u0026response-content-disposition=attachment%3B+filename%3DEducation_environnementale_implementatio.pdf\u0026Expires=1732505937\u0026Signature=VLwgmr1Qb0rTaIvWs82dRKZ-KPwpv1rBWXAIbrnFudYhB4E8l5RcFaOMQsz27MhTni7PzY4o7MEj6tswcrK51ezTTDi5Zxb7xJdcwhrzR00fT6BRD4lv0ZSniWYpDDkTsfauHX3FS3Rxc-KsW-98eZgUOId8qYaJCGGcVgeS6ltUNu~tdUNU5HdC2gGWIzS4Yooos1ekdQ~DM-LR5Vm5hDoWqsOgN3vrQD0eDBRu7n~WzRdPwnyEgpExwo8EjPsmMWDUwv60awH1IUMRrFXoDKr8qqfWjO0YSUwH-ykMl4chqCxnAKf0el8fCKHfX7S2qs8X7hI-cVK3XLnXlYuHhg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","download_file_url":"https://www.academia.edu/attachments/111430309/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&","full_thumbnail_url":"https://0.academia-photos.com/attachment_thumbnails/111430309/mini_magick20240213-1-wgndqh.png?1707829712"}],"has_pdf":true,"has_fulltext":true,"page_count":30,"ordered_authors":[{"id":199802241,"first_name":"Issa","last_name":"ZONGO","domain_name":"ens","page_name":"IssaZONGO","display_name":"Issa ZONGO","profile_url":"https://ens.academia.edu/IssaZONGO","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":81403,"name":"Burkina Faso","url":"https://www.academia.edu/Documents/in/Burkina_Faso","nofollow":false},{"id":2469674,"name":"Outils didactiques","url":"https://www.academia.edu/Documents/in/Outils_didactiques","nofollow":false},{"id":4459786,"name":"Déchets plastiques","url":"https://www.academia.edu/Documents/in/D%C3%A9chets_plastiques"},{"id":4459787,"name":"Polymère","url":"https://www.academia.edu/Documents/in/Polym%C3%A8re"},{"id":4459788,"name":"Éducation Environnementale","url":"https://www.academia.edu/Documents/in/%C3%89ducation_Environnementale"}],"publication_year":2024,"publication_year_with_fallback":2024,"paper_rank":null,"all_time_views":53,"active_discussion":{}}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_116816729" data-work_id="116816729" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/116816729/Trajectoire_r%C3%A9sidentielle_des_d%C3%A9plac%C3%A9_e_s_internes_et_migrant_e_s_%C3%A0_Ouagadougou">Trajectoire résidentielle des déplacé·e·s internes et migrant·e·s à Ouagadougou</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Ouagadougou, the capital of Burkina Faso, is a metropolis undergoing strong demographic and spatial growth, with a population now estimated at 3 million inhabitants for an area of 518 km2.

This rapid dynamic is <br />linked to natural growth and significant migration, both international, <br />with the displaced persons from the Ivorian conflict during the 2000s, <br />and internal, with the persistence of migratory flows from rural areas. <br />According to the Ouagadougou Population Observatory (OPO), 71% of <br />adults over 15 years of age were not born in the capital. This sustained <br />growth exerts extremely strong pressure on the residential situation of <br />natives and migrants, who are very often forced to live in the suburbs <br />of the city. This article analyses the residential trajectories of internal <br />and international migrants in Ouagadougou. This analysis is based on a <br />state of the art of urban migration in Burkina Faso, and on data from the <br />« Ouaga 2009 » study, used in the framework of our doctoral research. <br />Thus, the article discusses the birthplaces of Ouagadougou residents, <br />migration flows, the neighbourhoods of arrival and the reasons for <br />migration to Ouagadougou, as well as residential trajectories.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/116816729" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c4ff8026fc2f2793a170676fa88db29c" rel="nofollow" data-download="{"attachment_id":112841627,"asset_id":116816729,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/112841627/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23743917" href="https://ens.academia.edu/SERESEYDOU">SERE SEYDOU</a><script data-card-contents-for-user="23743917" type="text/json">{"id":23743917,"first_name":"SERE","last_name":"SEYDOU","domain_name":"ens","page_name":"SERESEYDOU","display_name":"SERE SEYDOU","profile_url":"https://ens.academia.edu/SERESEYDOU","photo":"https://0.academia-photos.com/23743917/106213466/95421043/s65_sere.sydney.png"}</script></span></span></li><li class="js-paper-rank-work_116816729 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="116816729"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 116816729, container: ".js-paper-rank-work_116816729", }); });</script></li><li class="js-percentile-work_116816729 InlineList-item InlineList-item--bordered hidden u-tcGrayDark"><span class="percentile-widget hidden"><span class="u-mr2x percentile-widget" style="display: none">•</span><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 116816729; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-percentile-work_116816729"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></li><li class="js-view-count-work_116816729 InlineList-item InlineList-item--bordered hidden"><div><span><span class="js-view-count view-count u-mr2x" data-work-id="116816729"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116816729; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=116816729]").text(description); $(".js-view-count-work_116816729").attr('title', description).tooltip(); }); });</script></span><script>$(function() { $(".js-view-count-work_116816729").removeClass('hidden') })</script></div></li></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_116850776" data-work_id="116850776" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/116850776/Strat%C3%A9gies_r%C3%A9sidentielles_des_jeunes_adultes_des_quartiers_de_la_ville_de_Ouagadougou_Burkina_Faso_">Stratégies résidentielles des jeunes adultes des quartiers de la ville de Ouagadougou (Burkina-Faso)</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Ouagadougou, the capital of Burkina Faso, is a metropolis with strong demographic and spatial growth.

It covers an area of 51,800 ha, or a density of 58<br />inhabitants. / ha (INSD, 2009, 2020). This rapid growth is linked to births, migrations (urban, rural exodus) and people displaced by crises (land, security). It exerts pressure on the residential situation of the ouagalans, often forced into difficult arrangements. As public supply is negligible<br />and the property market predominantly informal, young people are often forced to adopt strategies to gain access to housing and property. The main objective of the study is to analyze the residential strategies adopted by young adults in informal and precarious neighborhoods called<br />non-housing estates compared to their counterparts in housing estates in order to gain access to housing or to a plot. She hypothesizes that the residential strategies of young adults in housing estates differ from those of young people in non-housing estates. The methodology is based on<br />qualitative data (interviews) collected between 2014 and 2020 from 66 young adults from the different neighborhoods and non-housing estates of the city of Ouagadougou. The choice of young people was made in a reasoned way through criteria such as age, area of residence, activity carried out. These interviews were processed and used according to our study theme to achieve results.<br />Thus, five housing access strategies have been identified. These are strategies by non-housing estates, subdivisions, real estate developers, individuals and social housing.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/116850776" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="ef95c12ecddca9520eacbf63130e477b" rel="nofollow" data-download="{"attachment_id":112865999,"asset_id":116850776,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/112865999/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23743917" href="https://ens.academia.edu/SERESEYDOU">SERE SEYDOU</a><script data-card-contents-for-user="23743917" type="text/json">{"id":23743917,"first_name":"SERE","last_name":"SEYDOU","domain_name":"ens","page_name":"SERESEYDOU","display_name":"SERE SEYDOU","profile_url":"https://ens.academia.edu/SERESEYDOU","photo":"https://0.academia-photos.com/23743917/106213466/95421043/s65_sere.sydney.png"}</script></span></span></li><li class="js-paper-rank-work_116850776 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="116850776"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 116850776, container: ".js-paper-rank-work_116850776", }); });</script></li><li class="js-percentile-work_116850776 InlineList-item InlineList-item--bordered hidden u-tcGrayDark"><span class="percentile-widget hidden"><span class="u-mr2x percentile-widget" style="display: none">•</span><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 116850776; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-percentile-work_116850776"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></li><li class="js-view-count-work_116850776 InlineList-item InlineList-item--bordered hidden"><div><span><span class="js-view-count view-count u-mr2x" data-work-id="116850776"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116850776; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=116850776]").text(description); $(".js-view-count-work_116850776").attr('title', description).tooltip(); }); });</script></span><script>$(function() { $(".js-view-count-work_116850776").removeClass('hidden') })</script></div></li></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_117062626" data-work_id="117062626" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/117062626/Situation_des_infrastructures_%C3%A9ducatives_dans_un_contexte_d_ins%C3%A9curit%C3%A9_dans_la_r%C3%A9gion_du_sahel_au_Burkina_Faso">Situation des infrastructures éducatives dans un contexte d’insécurité dans la région du sahel au Burkina Faso</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The Sahel region is one of the regions heavily affected by insecurity in Burkina Faso.

Of the region's 1,098,177 inhabitants (INSD, 2019), approximately 574,000 are internally displaced persons (IDPs) (CONASUR, 2022). Education is one of the sectors most affected by insecurity.<br />In Dori alone, 62.02% of the 14,256 IDPs are children, most of whom are of school age (OCHA, 2022). This insecurity linked to terrorist acts has led to the closure of many schools. In this difficult context, what remains of the educational infrastructure? What is the school map of the Sahel region like? This research examines the situation of educational infrastructures in a context of insecurity in the Sahel region of Burkina Faso. It examines the functionality and equipment of educational infrastructure at the primary and secondary levels. The methodology is based on the analysis of data collected by the General Directorate of Territorial Development from March 14 to 25, 2022, in which we took part. It is a census of all the educational<br />infrastructures in all the communes of the Sahel region. The state of these infrastructures as well as their functionality were also informed. The data was collected using the KoBoCollect data collection application, installed on smartphones in which the questionnaire was deployed.<br />This allowed for rapid data collection by the commune focal points and geolocation of the infrastructure. The data collection made it possible to geolocate 1,232 educational infrastructures, including 888 public and private elementary school. <br />Key words: educational infrastructure, functionality, insecurity, Sahel.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/117062626" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="e28894aed549490493e4d0c92001c0d6" rel="nofollow" data-download="{"attachment_id":113021493,"asset_id":117062626,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/113021493/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23743917" href="https://ens.academia.edu/SERESEYDOU">SERE SEYDOU</a><script data-card-contents-for-user="23743917" type="text/json">{"id":23743917,"first_name":"SERE","last_name":"SEYDOU","domain_name":"ens","page_name":"SERESEYDOU","display_name":"SERE SEYDOU","profile_url":"https://ens.academia.edu/SERESEYDOU","photo":"https://0.academia-photos.com/23743917/106213466/95421043/s65_sere.sydney.png"}</script></span></span></li><li class="js-paper-rank-work_117062626 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="117062626"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 117062626, container: ".js-paper-rank-work_117062626", }); });</script></li><li class="js-percentile-work_117062626 InlineList-item InlineList-item--bordered hidden u-tcGrayDark"><span class="percentile-widget hidden"><span class="u-mr2x percentile-widget" style="display: none">•</span><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 117062626; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-percentile-work_117062626"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></li><li class="js-view-count-work_117062626 InlineList-item InlineList-item--bordered hidden"><div><span><span class="js-view-count view-count u-mr2x" data-work-id="117062626"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 117062626; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=117062626]").text(description); $(".js-view-count-work_117062626").attr('title', description).tooltip(); }); });</script></span><script>$(function() { $(".js-view-count-work_117062626").removeClass('hidden') })</script></div></li></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_117095465 coauthored" data-work_id="117095465" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/117095465/EFFETS_SOCIO_%C3%89CONOMIQUES_ET_ENVIRONNEMENTAUX_DE_L_OCCUPATION_DES_ESPACES_VERTS_DANS_L_ARRONDISSEMENT_N_6_DE_LA_COMMUNE_DE_OUAGADOUGOU">EFFETS SOCIO-ÉCONOMIQUES ET ENVIRONNEMENTAUX DE L’OCCUPATION DES ESPACES VERTS DANS L’ARRONDISSEMENT N°6 DE LA COMMUNE DE OUAGADOUGOU</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Abstract : The city of Ouagadougou is experiencing rapid demographic and spatial growth.

This sustained growth is having an impact on the city's development. Many of the city's green spaces are undeveloped. Their spontaneous and illegal occupation in the city is a problem for local authorities, particularly the arrondissements of the Ouagadougou commune. The aim of this article is to analyze and demonstrate the use and destination of green spaces in arrondissement 6 of the Ouagadougou<br />Commune. The aim is to study the various socio-economic and environmental implications. The objective of this article is to analyze the socio-economic and environmental effects of the use and destination of green spaces in the arrondissement 6 of the Municipality of Ouagadougou. The methodology used is based firstly on both scientific and institutional documentary research.<br />Subsequently, interviews were conducted with stakeholders from the administration, local authorities,<br />and residents between 2020 and 2022. These interviews were followed by on-site observations using<br />photographic equipment and GPS (Global Positioning System). The results show that the arrondissement 6 has 94 green spaces. Many green spaces are occupied by places of worship, various activities, or have become garbage dumps. As a result, many actors occupy these green spaces without official documentation. However, green spaces generate income for local authorities through the collection of taxes. <br />Keywords: Green space, urbanization, urban planning, Ouagadougou</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/117095465" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="884aacbf79a82f6b73a6a6136283e2f6" rel="nofollow" data-download="{"attachment_id":113045301,"asset_id":117095465,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/113045301/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23743917" href="https://ens.academia.edu/SERESEYDOU">SERE SEYDOU</a><script data-card-contents-for-user="23743917" type="text/json">{"id":23743917,"first_name":"SERE","last_name":"SEYDOU","domain_name":"ens","page_name":"SERESEYDOU","display_name":"SERE SEYDOU","profile_url":"https://ens.academia.edu/SERESEYDOU","photo":"https://0.academia-photos.com/23743917/106213466/95421043/s65_sere.sydney.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-117095465">+1</span><div class="hidden js-additional-users-117095465"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/TRAOREYaya14">TRAORE Yaya</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-117095465'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-117095465').html();

In Burkina Faso,specifically in the city of Bobo-Dioulasso, taxidrivers have chosen to convert vehicles designedto run on gasoline or diesel to operate on butanegas as a rational choice for increased profitability<br />The objective of this article is to demonstrate<br />how the rational choice of using butane gas by<br />taxi drivers shapes urban transportation in the<br />city of Bobo-Dioulasso. The aim is to study the<br />various economic and geographical implications<br />of using gas in the urban mobility sector in Bobo-Dioulasso. The methodology used is based on a literature review, both scientific and institutional. It allowed for the integration of rationality theory. Subsequently, an iterative survey involving interviews based on a semi-structured questionnaire was conducted with 125 taxi drivers during 2018-2019. These interviews were followed by field observations using photographic equipment and GPS.<br />The results reveal that economic reasons remain <br />the main motive for taxis to use domestic bu-<br />tane gas. Geographically, the use of gas leads to<br />avoiding certain areas during the rainy season<br />and provides a broader spatial scope of work at a<br />lower cost for the drivers. Moreover, the practice allows unlicensed tricycles to get involved in an<br />activity that wasn‘t intended for them.<br />Keywords : Bobo-Dioulasso, gas taxi, urban<br />mobility, public transportation, rational choice</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/117128785" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="775242c2eaaa07772652989d1094193c" rel="nofollow" data-download="{"attachment_id":113066959,"asset_id":117128785,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/113066959/download_file?st=MTczMjc1MTI3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23743917" href="https://ens.academia.edu/SERESEYDOU">SERE SEYDOU</a><script data-card-contents-for-user="23743917" type="text/json">{"id":23743917,"first_name":"SERE","last_name":"SEYDOU","domain_name":"ens","page_name":"SERESEYDOU","display_name":"SERE SEYDOU","profile_url":"https://ens.academia.edu/SERESEYDOU","photo":"https://0.academia-photos.com/23743917/106213466/95421043/s65_sere.sydney.png"}</script></span></span></li><li class="js-paper-rank-work_117128785 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="117128785"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 117128785, container: ".js-paper-rank-work_117128785", }); });</script></li><li class="js-percentile-work_117128785 InlineList-item InlineList-item--bordered hidden u-tcGrayDark"><span class="percentile-widget hidden"><span class="u-mr2x percentile-widget" style="display: none">•</span><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 117128785; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-percentile-work_117128785"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></li><li class="js-view-count-work_117128785 InlineList-item InlineList-item--bordered hidden"><div><span><span class="js-view-count view-count u-mr2x" data-work-id="117128785"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 117128785; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=117128785]").text(description); $(".js-view-count-work_117128785").attr('title', description).tooltip(); }); });</script></span><script>$(function() { $(".js-view-count-work_117128785").removeClass('hidden') })</script></div></li></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_117374536 coauthored" data-work_id="117374536" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/117374536/S%C3%A9curisation_fonci%C3%A8re_dans_la_plaine_am%C3%A9nag%C3%A9e_de_Mogt%C3%A9do">Sécurisation foncière dans la plaine aménagée de Mogtédo</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Abstract The hydro-agricultural plain of Mogtédo was developed in 1968 to contribute to the fight against food insecurity and promote economic development.

The disengagement of the State with the Agricultural Sector Structural Adjustment Program (PASA) starting from 1990 has led to several constraints, such as the degradation of hydroagricultural infrastructures, insufficient developed plots, drainage issues, and land<br />conflicts, among others. The Mogtédo plain is no exception. Several questions prompted this study, including whether the plain is registered and what are the modes of access and land management. <br />The objective of the study is to analyze the land security of the developed plain of Mogtédo. To achieve this, qualitative data were collected through interviews with key informants, administrative personnel, and plain producers. In addition to interviews, secondary data were also collected from relevant technical services in taxation and agriculture. The collected data were processed using Microsoft Word and Excel software. <br />The study's results reveal that the developed plain of Mogtédo is neither delimited,<br />nor demarcated, nor registered. No producer has land titles or others occupancy rights. This lack of security for producers leads to land conflicts.

It is managed by a semi-public company called Société de développement intégrée du pôle de Bagré, or "Bagrepole" for short. The ambition was to accelerate the structural transformation of the national economy through intensive economic development and local production. This new strategy focuses on public and private investment. The aim of the study is to analyze agricultural production in the Bagré growth pole and its contribution to food security in Burkina Faso. To this end, qualitative data were collected through interviews with the Bagrépôle administration, producers and processors. In addition to the interviews, secondary data were also collected from the appropriate technical services. The results of the study show, among other things, that the creation of the Bagré growth pole has increased production in all agroforestry sectors. Agricultural production rose from 55% over the 2012-2019 period to 86.18% over the 2019-2020 period, creating new economic activities in the project area and contributing to national food security.<br />Keywords: Bagré growth pole, food security, agricultural production</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/117375174" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="d80ec90266ad82b5d8fc6b2bd33b6b0e" rel="nofollow" data-download="{"attachment_id":113248313,"asset_id":117375174,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/113248313/download_file?st=MTczMjc1MTI3Myw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23743917" href="https://ens.academia.edu/SERESEYDOU">SERE SEYDOU</a><script data-card-contents-for-user="23743917" type="text/json">{"id":23743917,"first_name":"SERE","last_name":"SEYDOU","domain_name":"ens","page_name":"SERESEYDOU","display_name":"SERE SEYDOU","profile_url":"https://ens.academia.edu/SERESEYDOU","photo":"https://0.academia-photos.com/23743917/106213466/95421043/s65_sere.sydney.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-117375174">+1</span><div class="hidden js-additional-users-117375174"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/KIENTEGANaboswind%C3%A9">KIENTEGA Naboswindé</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-117375174'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-117375174').html();
