Texte intégralRésumé :
Concernant le parcours de soins en santé mentale « L’objectif est d’améliorer sur le terrain, par des outils et des recommandations de bonne pratique, le parcours de soins et la qualité de vie des personnes présentant des troubles mentaux », précise la direction de l’amélioration de la qualité et de la sécurité des soins de la HAS. Le centre F. Minkowska géré par l’association F. et E. Minkowski a mis en perspective cet objectif pour une population migrante et refugiée afin, d’une part, d’éviter toute ghettoïsation des pratiques cliniques et, d’autre part, le souci de répondre à la demande en proposant une offre de soin tout à fait conforme au droit commun et avec un éclairage santé publique. Le projet d’établissement de ce centre medico-psychosocial s’articule sur la valorisation des bonnes pratiques en les déclinant sur trois volets. Le volet théorique autour des représentations sociales et culturelles de la santé et de la maladie mentale, le volet organisationnel avec la mise en place d’un dispositif (Mediacor) permettant d’améliorer l’accès aux soins pour les personnes migrantes et refugiées et enfin, le volet clinique avec un cadre thérapeutique reposant sur la notion de compétence culturelle. Ces trois aspects permettent de mieux appréhender les obstacles identifiés dans le parcours de soin et, par conséquent, d’y remédier.

Texte intégralRésumé :
Le Centre Françoise-Minkowska, centre médicopsychosocial reçoit des personnes migrantes et réfugiées de toute l’Île-de-France, qu’elles soient orientées par un professionnel de la santé mentale ou du social. L’offre de soins disponible s’appuie sur la compétence culturelle des thérapeutes et des travailleurs sociaux. En effet, le centre va au-delà de l’offre ethnopsychiatrique classique en proposant un accès aux soins tenant compte de la dimension linguistique et des représentations culturelles de la maladie mentale. Dans l’espace sanitaire de l’Île-de-France, cette possibilité ouvre des perspectives conformes au droit commun et aux exigences de la santé publique. Par ailleurs, une unité de médiation, d’accueil et d’orientation (MEDIACOR) permet d’optimiser cette offre de soins.

Texte intégralRésumé :
Cette recherche en soins vise à identifier, nommer, qualifier et surtout caractériser les fonctions de l’informel dans le soin infirmier en psychiatrie, particulièrement dans l’écart entre soins programmés et soins non programmés. Il s’agit alors d’objectiver les savoirs faire mobilisés, mais aussi leurs impacts et leurs spécificités. Les objectifs de cette recherche en soins infirmiers (RSI) sont mobilisés sur trois niveaux d’investigations : en direction du patient, du professionnel et de l’équipe.Cette recherche multicentrique a connu sa phase d’enquêtes de terrain auprès d’équipes de soins d’unités d’hospitalisation temps plein de quatre établissements de la région Rhône Alpes, établissements représentatifs de l’offre de soins publique sectorisée. Les enquêtes ont allié trois outils d’investigation : des « entretiens semi-dirigés », des séquences « d’observations participantes périphériques » et des « dialogues en interaction avec l’action ». Le traitement de ces données de terrain a abouti à la détermination de 3100 unités d’actions en lien avec l’informel.Nous nous appuyons dans nos axes théoriques sur les apports et les invariants structuraux de la psychothérapie institutionnelle, de la psychodynamique du travail ainsi que de la praxéologie. Les résultats se présentent sous une triple forme. Tout d’abord, le cœur de la recherche avec la caractérisation de 139 fonctions en lien avec l’informel dans les soins, puis l’approche quantitative de ces données qualitatives (variable de lieux, de temps, de sites, etc.) et enfin le dégagement d’invariants opératoires, pour les caractéristiques communes à tous les sites investigués.Cette recherche et ses résultats sont en mesure d’établir sur des données valides, bien des zones invisibles et peu lisibles du travail institutionnel et des savoirs infirmier en psychiatrie. La caractérisation de ces attentions, de ces « micro-actes » et « micro-interventions » concourent à un « prendre soin » individuel et collectif, participent d’un climat relationnel, ouvrent à des espaces transitionnels ou se déploient aussi bien des actions de cognition sociales que les différentes dimensions de la proxémie, de l’empathie et du « care ».

Texte intégralRésumé :
Nous décrivons un dispositif d’hospitalisation temps complet pour adolescents souffrant de douleurs chroniques touchant le système musculosquelettique. Ce dispositif associe soins de rééducation fonctionnelle et accompagnement pédopsychiatrique. Les médiations corporelles, le travail familial et la remise en situation scolaire au sein de notre établissement de type « SoinsÉtudes » sont les trois piliers de la prise en charge. La pertinence et les limites de ces hospitalisations pour cette indication sont discutées. Dans une perspective attachementiste nous émettons par ailleurs l’hypothèse que la plupart de ces enfants présentent un style d’attachement de type « contrôlant thérapeute » envers leur environnement familial ce que ces hospitalisations permettent souvent de révéler.

Texte intégralRésumé :
L'étude vise les raisons, les connaissances et les attentes des personnes subissant une chirurgie bariatrique au Moyen-Orient et en Jordanie. Une étude rétrospective a été conçue et menée au Centre de la prise en charge de l'obésité Mohammad Al-Zitawi entre 2015 et 2017. 154 patients (hommes: 45; femmes: 109) - ayant une masse corporelle supérieure à 40 kg / m2 et âgés de 20 à 60 ans- ont participé à l'étude. Ils ont été choisis au hasard. Ils représentaient 10% des patients adultes au centre de l'obésité de la période de l'étude. Âgés de 20 à 60 ans, les participants a l'étude ont été orientées vers l'unité bariatrique du Centre Al-Zitawi. Le comité d'éthique du centre a approuve le protocole de l'étude. Tous les aspects éthiques ont été respectes au cours de l'enquête. La bienfaisance (bien faire), la non-malfaisance (ne justifie pas les patients), la fidélité, la confiance, le respect, le traitement impartial, le respect culturel, le droit à la justice, le respect de la confidentialité, le droit à la prise de décision et la décision volontaire ont été prises en compte. Il s'agit d'une étude rétrospective. Deux questionnaires ont été conçus: un pour les patients et l'autre pour les professionnels impliqués de la prise en charge de l'obésité. Les entretiens et le consentement des patients ont été obtenus par téléphone (chez eux, loin du centre). Les questions de l'étude a opte l'approche des méthodes mixtes pour améliorer la qualité des données collectées.Il s'agit d'une méthodologie de recherche croissante. Elle fait progresser le mélange systématique de données qualitatives et quantitatives au sein d'une même enquête ou d'un programme de recherche constant. Elle permet une utilisation complète et synergique des données. Elle donne toutefois la parole aux participants et les résultats sont basés sur l'expérience des participants. Elle laisse une place à l'équipe multidisciplinaire par la recherche en favorisant le contact des chercheurs en méthodes quantitatives, qualitatives et mixtes (Creswell et al., 2011). Les résultats montrent que les patients du Moyen-Orient n'avaient pas de connaissances et de compréhension à propos de la chirurgie bariatrique Les études de Taube-Schiff et al. (2016) et Guler et al. (2018), indiquent que les patients obèses, même dans les pays développés, ont peu de connaissance à propos des chirurgies bariatriques, Une étude récente saoudienne d'Altaf & Abbas (2019) révèle que la sensibilisation du public à l'obésité et à la chirurgie bariatrique est très limitée. Notre étude révèle une insuffisance évidente a propos de la prise de conscience et la connaissance de la chirurgie bariatrique chez les patients participants du Moyen-Orient. Différentes plates-formes sont essentielles pour mieux faire connaître la chirurgie bariatrique et ses avantages, ses facteurs de risque et ses complications associés. La revue des pratiques des chirurgiens et des éducateurs sanitaires est évidente. La plupart des patients de l'étude n'ont pas apprécié le service rendu et les bénéfices de la chirurgie. La sensibilisation du public, les services de gestion du poids, du changement de comportement et de la gestion de soi sont essentiels pour améliorer le service rendu à long terme de la chirurgie bariatrique et répondre aux attentes des patientsThe study aimed to understand the reasons, knowledge and expectations of people undergoing bariatric surgery in Middle East and Jordan. A retrospective study is designed and was conducted in the Mohammad Al-Zitawi Obesity Management Centre between the years 2015 and 2017. A total of 154 participants (males: 45; females: 109) who had body mass greater than 40kg/m2 and aged between 20-60 years took part in the study. The study participants were randomly selected and enrolled participants were 10% of the patients who attended obesity management centre in that particular year. All study patients were above 20 years of age and had been referred to the bariatric unit at Al- Zitawi Obesity Management Centre. A total of 154 patients (males: 45; females: 109) who had body mass greater than 40kg/m2 and aged between 20-60 years took part in the study. Ethical approval for the study was taken from hospital ethical committee. At the time of filling up of questionnaire forms all ethical aspects such as beneficence (doing good), non malfeasance (not justifying patients), fidelity, trust, respect, unbiased treatment, cultural respect, right to justice, maintenance of confidentiality, right to decision making and voluntary decision were taken into consideration. The methodology involves two tier questionnaires; one for patients and the other one for the professionals involved in obesity management. Since, it is a retrospective study and participants are not in the city. Questionnaire forms and patients consent was obtained on phone from the participants. Filling up of questionnaire form was on phone. Questions were explained to participants on phone in English and Islamic language and consent was obtained. In the present study, we used mixed method approach to improve the quality of our research study. Mixed method approach refers to growing methodology of research that progress the systematic mixing of both qualitative and quantitative datum within a single investigation or constant programme of investigation. Mixed up approach allows complete and synergic use of data. Furthermore, this method gives voice to study participants and make sure that enrolled participants are part of study and results are base on participant's experience. This kind of approach provides space to multidisciplinary team by research by promoting the contact of quantitative, qualitative, and mixed methods scholars (Creswell et al., 2011). The results of our study showed that patients in the Middle East do not have much knowledge and understanding about the bariatric surgery and this finding is in consistent with the studies of Taube-Schiff et al. (2016) and Guler et al. (2018) indicating that usually obese patients have limited knowledge about bariatric surgeries even in the developed countries. Moreover, a recent research documented by Altaf & Abbas (2019) in Saudi Arab documents that the public awareness about obesity and bariatric surgery is very limited. Our study shows an obvious gap in awareness and knowledge about bariatric surgery among the studied participants from the Middle East. There is a need of using different platforms for spreading accurate awareness about Bariatric surgery and its associated benefits, risk factors and associated complications. Public awareness should be created by surgeons and health educators and they should act accordingly to develop better knowledge and awareness among general public. Most of patients in our study fail to meet their expectations from surgery as benefits of treatment. Our study also throws light on the significance of weight management services, behavioural change and self management in modifying patient's expectations of having long term benefits of bariatric surgery

Texte intégralRésumé :
Que se passe-il lorsqu'un problème public émerge et se diffuse au carrefour de deux politiques publiques naguère sans liens directs et régies par des référentiels différents, voire opposés? Comment examiner du point de vue théorique le croisement et la contradiction en analyse des politiques publiques? Quel apport théorique peut être attendu d'une recherche empirique portant sur les controverses, les formes de légitimations et les modes de régulation régissant ce genre de contradictions? Cette thèse est consacrée à l'analyse de l'action publique en direction des migrants atteints par le VIH/sida ou exposés au risque d'infection. Elle concerne deux politiques sectorielles et deux réalités sociales aux effets liés et parfois contradictoires : celle de lutte contre l'immigration d'une part et celle de santé publique et de lutte contre le sida d'autre part. Elle analyse le traitement politique et public du problème des étrangers atteints par une pathologie grave et vivant en France. Ce problème a tardivement été inscrit sur l'agenda public en raison de plusieurs facteurs. La publication en 1999 de statistiques épidémiologiques sur le sida chez les étrangers a montré la vulnérabilité particulière des étrangers par rapport au sida et a ouvert grâce à la mise en place de programmes publics, des actions publiques et privées ciblant directement les populations originaires d'Afrique subsaharienne. Cependant, l'augmentation dans les statistiques du nombre d'étrangers atteints par le VIH/sida va entraîner des conflits et des controverses entre les acteurs de santé publique et les acteurs de lutte contre l'immigration. Dans un contexte politique marqué par la restriction des droits des étrangers, l'étude montre comment les dispositifs législatifs et réglementaires accordés à une catégorie spécifique d'action publique, celle des "étrangers gravement malades" résiste à cette logique de lutte contre l'immigration aussi bien au niveau national que local. Cette résistance portée par les acteurs de santé et les associations de défense des étrangers se manifeste en même temps au niveau interministériel et au niveau de la mise en œuvre de ces dispositifs grâce à des acteurs incontournables comme les associations et les professionnels de santé et du socialThe public action among migrants living with Aids is at the crossroads of a social policy and a restrictive policy. The stakeholders in the junction of these two policies are always oblige to take into account the opposite logics if these two policies. Our aim is to analyze the acting of stakeholders in the junction of these two policies. This analyze involve many issues. In the origin and host countries, the bonds between these two policies question's the migration of patients living with AIDS in search of the last therapeutic projections or treatments essential to their survival. In the countries of origin particularly in Sub-Saharan Africa, the link between health and migration question's the push factors of "health tourism". The social and political contexts in those countries encourage people to leave their own countries. Some of them know their Aids status before leaving their countries but a lot of them ascertain their Aids status in host countries. What is the scope of health tourism concerning Aids in France? Who are these patients who emigrate (statute, sex, level of studies. . . ) which is the place of health in their migration project? In the host countries the arrival of foreign patients living with Aids in efficient health. Systems but nevertheless in crisis, also question's the Universalist aiming of the health system particularly in France. These issues and the debates which they cause are often put, at the political agenda by politicians, in terms of costs of their health care and the increase of the number of new recipients in medical benefits. On the level of the implementation of the policy against Aids, the issue of migrants living with Aids also question's the working and logics of the health services witch are not adapted to these immigrant populations in terms of cultural and social issues? Which are the problems raised by health care of migrants living with Aids in the France? Which are the strategies and programs implemented to improve health care among migrants living with AIDS? The inscription on the political agenda of the issue of migrants living with AIDS and in precarious situation, requires an important social and medical treatment? How this specific care is organized in hospitals? How the social professionals are integrated in care for migrants living with AIDS? Which are the resources mobilized for this socio-medical care? The care of migrants asks also the question of cultural dimensions of health care among these populations. Some organizations recruit cultural mediators to improve the health care of migrants. How those professionals are integrated in health services? Which are their roles? ln this context of development of immigration policy control, the health and AIDS sector seems to escape from the restrictions of foreigners rights

Texte intégralRésumé :
Le secteur de la santé est en pleine mutation, caractérisé par une dynamique d'innovation très forte et un contexte particulier donnant lieu à une multitude de réformes. En conséquence, la rapidité d'évolution des métiers, notamment leurréorganisation est restée incompréhensible pour beaucoup de professionnels. Dans ce sens, afin comprendre la dynamique des métiers notre question de recherche se formule ainsi : En quoi la compréhension du processus de structuration des métiers permet-elle, dans un contexte d'innovation, de mieux gérer leur dynamique ? Tout en adoptant la prospective des métiers comme cadre global de réflexion, notre recherche vise à mieux appréhender les phases amont du processus de structuration des métiers dans un contexte d'innovations. Afin de répondre notre questionnement, cette recherche s'organise en deux parties : Dans la première partie, l'analyse conceptuelle et celle du secteur de la santé, nous ont permis de cerner les différents concepts concourant à notre problématique. En outre, l'historiographie du métier d'infirmière nous a permis d'établir une première approche du processus de structuration, ses phases et les différents sous-processus intervenant dans le processus de structuration globale. Dans la seconde partie, les résultats de l'étude de trois métiers ont été exposé : Le métier d'infirmière Conseillère en hygiène (ICH), le conseiller en génétique (CG), et enfin celui de dosimétriste. Sur un plan méthodologique, l'adoption d'une démarche de recherche qualitative comme stratégie d'accès au terrain, avec l'entretien semi-directif d’experts (46 entretiens) comme outil de collecte des données, nous a permis d’aller au coeur de la problématique. En outre, la riche documentation, notamment le recours à la « nétnographie » s'est révélé capital dans la prise en compte du niveau systémique et la compréhension des réels mécanismes apportés par le processus social, moteur de changement, dansla dynamique du processus global de structuration. L'analyse des différents métiers, nous a permis d'identifier cinq sous-processus, dont la dynamique concoure à la formation du processus global de structuration : processus d'innovations, processus d'apprentissage, processus conceptuel, processus social et enfin un processus de professionnalisation. Enfin la conclusion générale permet de résumer les principaux apports théoriques, méthodologiques et managériaux de cette recherche, ainsi que les limites qui nous permettrons d'ouvrir les futures voies de recherche

Benton, Joshua Robert. « Temporal Dynamics of Groundwater Flow Direction in a Glaciated, Headwater Catchment ». Thesis, Virginia Tech, 2020. http://hdl.handle.net/10919/104222.
Texte intégralRésumé :
Shallow groundwater flow in the critical zone of steep headwater mountain catchments is often assumed to mimic surface topography. However, groundwater flow is influenced by other variables, such as the elevation of the water table and subsurface hydraulic conductivity, which can result in temporal variations in both magnitude and direction of flow. In this study, I investigated the temporal variability of groundwater flow in the soil zone (solum) within the critical zone of a headwater catchment at the Hubbard Brook Experimental Forest in North Woodstock, NH. Groundwater levels were continuously monitored throughout several seasons (March 2019 to Jan 2020) in a network of wells comprising three hillslope transects within the upper hillslopes of the catchment. Five clusters of three wells per cluster were screened from 0.18 – 1.1 m depth at the base of the solum. Water levels were also monitored in five deeper wells, screened from 2.4 - 6.9 m depth within glacial sediments of the C horizon. I conducted 47 slug tests across the well network to determine hydraulic properties of the aquifer materials surrounding each well. In addition, our team conducted a large-scale auger investigation mapping soil horizon depths and thicknesses.
Results show that the magnitude of hydraulic gradients and subsurface hydrologic fluxes varied at each site with respect to changing water-table elevation, having a maximum range of 0.12 m/m and 9.19 x 10-6 m/s, respectively. The direction of groundwater flow had an arithmetic mean deviating from surface topography by 2-10 degrees, and a total range that deviated from surface topography by as much as 51 degrees. During lower water table regimes, groundwater flow direction deviated from the ground surface, but under higher water table regimes, in response to recharge events, flow direction mimicked surface topography. Within most of the well clusters, there is an observable connection between the slope direction of the top of the C horizon and the direction of groundwater flow during lower water table regimes. Slug test results show the interquartile range of saturated hydraulic conductivity (K¬sat¬) within the C horizon (1.5×10-7 to 9.8×10-7 m/s) is two orders of magnitude lower than the interquartile range of K¬sat¬ values within the solum (2.9×10-5 to 5.2×10-5 m/s). Thus, the C horizon is on average a confining unit relative to the solum that may constrict groundwater flow below the solum. Additionally, results from the larger scale auger investigation suggest that deviations in subsurface topography of the C horizon may be generalizable at the larger hillslope scale. Overall, these results indicate that 1) shallow groundwater flow direction and magnitude within this headwater catchment are dynamic and can deviate from surface topography, and 2) the subsurface topography of the C horizon can influence groundwater flow direction. These results imply that temporal dynamics of groundwater flow direction and magnitude should be considered when characterizing subsurface flow in critical zone studies. Additionally, knowledge of subsurface topography of confining units may provide constraints on the temporal variability of groundwater flow direction.M.S.
Streams that originate at higher elevations (defined as headwater streams) are important drinking water sources and deliver water and nutrients to maintain freshwater ecosystems. Groundwater is a major source of water to these streams, but little is known about how groundwater flows in these areas. Scientists delineate watersheds (areas of land that drain water to the same point) using surface topography. This approach works well for surface water, but not as well for groundwater, as groundwater may not flow in the same direction as surface water. Thus, assuming that the ground-watershed is the same as the surface watershed can lead to errors in hydrologic studies. To obtain more accurate information about groundwater flow in headwater areas, I continuously measured groundwater levels in forest soils at the Hubbard Brook Experimental Forest in North Woodstock, NH. My main objective was to determine if there is variability in the direction and amount of groundwater flow. I also measured the characteristics of the soils to identify the thicknesses of soil units and the permeability of those units. I used these data to evaluate the relationship between groundwater flow direction, surface topography, and the permeability of soil units. Overall, I found that groundwater flow direction can differ significantly from surface topography, and groundwater flow direction was influenced by the groundwater levels. When groundwater levels were high (closer to the land surface), groundwater flow was generally in the same direction as surface topography. However, when groundwater levels were lower, flow direction typically followed the slope of the lowest permeability soil unit. These results suggest that scientists should not assume that groundwater flow follows the land surface topography and should directly measure groundwater levels to determine flow direction. In addition, results from this study show that characterizing soil permeability can help scientists make more accurate measurements of groundwater flow.

Gueyraud, Cédric. « Jeu et maladie d'Alzheimer : le jeu libre comme intention de soin en direction de résidents d'EHPAD atteints de la maladie d'Alzheimer ou troubles apparentés ». Thesis, Lyon, 2018. http://www.theses.fr/2018LYSE2050.
Texte intégralRésumé :
Cette recherche interroge la question du jeu dans les EHPAD accueillant des personnes âgées atteintes de la maladie d’Alzheimer ou troubles apparentés. Elle a été réalisée dans le but d’inscrire le jeu libre et son cadre au cœur des projets d’établissements.Après une présentation de la maladie d’Alzheimer et de sa prise en charge non pharmacologique, une exploration de l’utilisation du jeu dans le soin été réalisée nous conduisant à réinterroger le concept de jeu, ses modalités de mise en œuvre et l’intérêt de viser le plaisir du jeu en première intention.Trois démarches distinctes ont ensuite été menées en parallèle. La première, dialectique et relativiste, tente de mettre en lien les enseignements offerts par les sciences du jeu avec la philosophie actuelle de la prise en soin des résidents d’EHPAD atteints de la maladie d’Alzheimer. La seconde démarche, vise à présenter les conditions matérielles et humaines pour la mise en place d’un cadre ludique adapté à la population en s’inspirant du modèle des ludothèques. Enfin, la troisième démarche, biomédicale, évalue l’impact de la situation de jeu libre dans une étude randomisée en simple aveugle auprès de 54 résidents dans six établissements. Des échelles et questionnaires ont permis d’évaluer la qualité de vie des résidents, leurs troubles du comportement ainsi que appréhension de l’outil de médiation par les soignants.La discussion des résultats interroge le cadre du jeu libre comme un objet frontière à l’interface du divertissement et de la thérapie non médicamenteuse. La médiation peut être mise en perspective d’une application clinique du modèle théorique contemporain de la résilience du sujet âgé et se présenter comme une application concrète des doctrines pédagogiques en éducation nouvelleThe purpose of this PhD research is to evaluate the usefulness of games in eldercare homes (EHPAD in French), for people who suffer from Alzheimer’s disease and diseases related to Alzheimer’s. It was carried out in order to include free play in the wider scope of the homes’ project. After a presentation on Alzheimer’s disease and a non-pharmacological approach to care, an in-depth study of the issue will be given, based on the review of medical literature that leads us to reconsider game design and implementation. This study used three different approaches that were implemented simultaneously. The first one presents the human and material working conditions that are necessary to set up a framework for the game, making certain that it is adapted to the people concerned. Game libraries and therapeutic mediations served as models. The second step, which is relativistic and dialectical, attempts to associate the benefit of game playing with the current approach to treating eldercare home residents who suffer from Alzheimer’s disease. Finally, the biomedical model evaluates the impact of the game in a randomized single-blind study of 54 residents in six eldercare homes. Different scales were used to assess the residents’ quality of life. The behavioral disorders were evaluated. The caregivers were given questionnaires to determine their understanding of the mediation tool used.The analysis of the findings supports free play as a tool which has both entertainment and therapeutic value.

This Master’s Dissertation had as its main goal analyzing and formalizing how Brazilian learners of English language (L2) and Americans identify and discriminate the voicing patterns for plosive consonants under artificial manipulation in English monossilabic words. Americans normally follow the acoustic cue Voice Onset Time (VOT) to differentiate voiced plosives from voiceless ones. The VOT is measured in milisseconds and can be classified into three different categories (LISKER & ABRAMSON, 1964): negative VOT (for /b/, /d/ and /g/ in Portuguese); short-lag VOT (for /p/, /t/, /k/ in Portuguese and /b/, /d/, /g/ in English) and long-lag or positive VOT (for [ph], [th], [kh] in English). Previous studies (ALVES, BARATZ e MOTTA, 2012; SCHWARTZHAUPT, ALVES &FONTES, 2015; ALVES & MOTTA, 2014; MOTTA, 2014; ALVES & ZIMMER, 2015) demonstrated that the manipulation of VOT can result into different types of perceptual behaviour, depending on the group analyzed: Americans tend to follow this cue to attribute voicing patterns to consonants, while Brazilians tend to follow the voicing patters stablished for their L1. In order to analyze the perception in L2, this Dissertation was based on Speech Learning Model (SLM) – (FLEGE, 1995) and Perceptual Assimilation Model – L2 (PAM-L2) – (BEST e TYLER, 2007) studies. To investigate how perception was processed in Americans, explanations in Kent and Read (2015), Gussenhoven and Jacobs (2004), Matzenauer (2015) and Boersma, Escudero and Hayes (2003) were found. The method consisted of two perceptual tests: (a) Identification Test, (b) Discrimination Test. Both tests were designed with artificially manipulated stimuli. The types (pee, pit, tick, tip, kit, kill) were CVC (where V was a high vowel /ɪ/ or /i/). Each one of them was multiply manipulated, generating five tokens from one original type. This manipulation was gradually performed, in 25% layers, aiming to achieve the zero artificial VOT pattern. The Identification Test was designed with 60 target words and 12 distractors, resulting in 72 tokens per participant. The Discrimination Test was designed with 36 target trials and 9 catch-trials, in a total of 45 trials per participant. To summarize, results show that Americans can be considered to be more perceptually sensitive to the multiple VOT manipulation than Brazilians, who normally tend to follow their L1 way of attributing voicing patterns to plosives, regardless their proficiency level in English (basic, intermediate or advanced). In addition, different phonetic tresholds were found in each analyzed group and in each place of articulation observed (bilabial, alveolar, velar). Finally, this study tries to offer a formalization for perceptual grammars in each group, based on Bi-directional Phonology OT Model (BiPhon). It is expected that this study, its detailed data description and theoretical observations can contribute to and makefurther academic studies possible.
Esta Dissertação de Mestrado teve como principal objetivo analisar e formalizar de que forma brasileiros aprendizes de inglês (L2) e americanos identificam e discriminam o vozeamento das consoantes plosivas iniciais da língua inglesa sob múltiplas manipulações em palavras monossilábicas. Na língua inglesa, para a diferenciação de vozeamento, tem-se como principal pista acústica a aspiração, que pode ser medida a partir dos valores de Voice Onset Time (VOT). O VOT é medido em milissegundos e pode ser classificado em 3 diferentes padrões (LISKER & ABRAMSON, 1964): VOT NEGATIVO (que se realiza foneticamente em português em /b/, /d/ e /g/); VOT ZERO, (que se realiza como /p/, /t/ e /k/ no português e /b/, /d/ e /g/ no inglês) e o VOT POSITIVO (encontrado em [ph], [th] e [kh] no inglês). Estudos anteriores (ALVES, BARATZ e MOTTA, 2012; SCHWARTZHAUPT, ALVES &FONTES, 2015; ALVES & MOTTA, 2014; MOTTA, 2014; ALVES & ZIMMER, 2015) demonstraram que a manipulação da pista acústica VOT resulta em comportamentos perceptuais diferenciados de acordo com a natureza do participante: americanos tendem a seguir a pista acústica em questão ao atribuir ou não vozeamento para as consoantes plosivas, ao passo que os brasileiros continuam a seguir os padrões de vozeamento previstos para a sua L1. Para dar conta da percepção em inglês como L2, este trabalho fundamentou-se, basicamente, nos modelos perceptuais Speech Learning Model (SLM) – (FLEGE, 1995) e Perceptual Assimilation Model – L2 (PAM-L2) – (BEST e TYLER, 2007). Para analisar a percepção dos participantes americanos, buscaram-se explicações em Kent e Read (2015), Gussenhoven e Jacobs (2004), Matzenauer (2015) e Boersma, Escudero e Hayes (2003). O método aplicado neste estudo consistiu em dois testes de percepção: (a) Teste de Identificação, (b) Teste de Discriminação. Ambos foram montados com estímulos de palavras monossilábicas da língua inglesa (CVC), sendo V /ɪ/ ou /i/. Cada type (pee, pit, tick, tip, kit, kill) passou por manipulação múltipla da pista acústica VOT, gerando 5 tokens cada um. Tal manipulação se deu de forma gradual em camadas de 25%, objetivando-se alcançar o padrão de VOT zero artificial. O design do Teste de Identificação contou com 60 palavras-alvo e 12 distratoras, somando um total de 72 tokens por participante. O design do Teste de Discriminação, que teve por objetivo contrastar diferentes camadas de VOT entre si, contou com 36 tríades do tipo AxB e 9 catch-trials, somando 45 tríades por participante. Sucintamente, os resultados apresentados demonstraram que os participantes americanos são mais sensíveis ao corte da pista acústica VOT do que os participantes brasileiros, independentemente do nível de proficiência em língua inglesa (básico, intermediário e avançado). Além disso, limiares fonéticos distintos foram encontrados em cada um dos grupos analisados e em cada ponto de articulação observado (bilabial, alveolar, velar). Finalmente, propôs-se uma formalização da percepção de ambos os grupos para cada consoante analisada baseando-se no Modelo de OT Bidirecional (BiPhon), proposto por Boersma (2009) e Boersma e Hamman (2011). Espera-se, com este estudo, que a descrição detalhada dos dados e a reflexão teórica possam contribuir à Academia e possibilitar estudos futuros.

Texte intégralRésumé :
The geological profile of submerged slopes on the continental shelf typically includes soft cohesive soils with thicknesses ranging from a few meters to tens or hundreds of meters. The response of these soils in simple shear tests is largely influenced by the presence of an initial consolidation shear stress, inducing anisotropic stress-strain-strength properties which depend also on the direction of shear. In this paper, a new simplified effective-stress-based model describing the behavior of normally to lightly overconsolidated cohesive soils is used in conjunction with a one-dimensional seismic site response analysis computer code to illustrate the importance of accounting for anisotropy and small strain nonlinearity. In particular, a simple example is carried out to compare results for different slope inclinations. Depth profiling of the maximum shear strains and permanent deformations provide insight into the mechanisms of deformation during a seismic event, and the effects of sloping ground conditions.

Texte intégralRésumé :
Bone, a key part of the paleontological and archeological records, can provide insight into the biology, ecology and the environment of ancient vertebrates. Bone is a composite material in which the nanomechanical properties are dependent on the local organic content, mineral content, and microstructural organization. However it is unclear as to how these properties are affected by burial, environmental influences, temperature, or time. The acidity of volcanic soils causes resorption of the bone mineral and may result in demineralization of the bone. As such, very few bone remains are found in volcanic soils and this rare sample can provide insight into the preservation under such extreme conditions. While the effects of volcanic soils on bone are unknown, exposure to hostile environmental conditions increases the potential for dramatic alteration of the mechanical behavior. In this study, a human long bone from around 600 A.D. and a modern human femur were studied using nanoindentation. Testing, performed in both longitudinal and transverse directions, revealed preservation of bone’s natural anisotropy. Additionally, the preserved bone’s lower modulus values suggest the dissolution of bone mineral.

Texte intégralRésumé :
Marine pipelines encounter significant dynamic forces due to the action of waves. In order to reduce such forces, they are buried below the seabed. The wave force on the pipeline at any depth of burial for the given hydrodynamic condition depends on the properties of the sea bed soil. Physical model is used for assessing the hydrodynamic force on the pipeline for a wide range of random wave conditions, for different burial depths and in four types of soils. It is found that for all the four soil types, the horizontal force reduces with increase in depth of burial, whereas the vertical force generally increases up to certain depth of burial, mainly due to the significant change in the magnitude as well as the phase lag between the pore water pressures in the vertical direction. Among the soils, well graded soil is good for half burial of pipeline, since the least vertical force occurs for this soil. On the other hand, uniformly graded and low hydraulic conductivity soil attracts the maximum vertical force for half burial. On the other hand, such soil is good for full burial or further increase of burial, since it attracts less vertical force when compared to the other soils. The results of this study will help the submarine pipeline design engineers to select the minimum safe burial depth in a range of cohesion-less soil.

Texte intégralRésumé :
The article deals with the problem of using crane-boring machines in the construction of communication lines and power transmission lines, the installation of fence posts and road signs, as well as in the construction of reclamation facilities. The data of experimental studies of these machines in the field to determine the rational modes of their operation in thawed soils are given. As a result of the research, it was found that the analysis of previous studies of the drilling modes of thawed soils does not give a clear idea of the existence and location on the response surface of the area of optimum drilling speed, taken as an optimization parameter. The necessity of researches is emphasized from the description of the area of the response surface by the polynomial of the first degree with the subsequent movement along its surface in the direction of the gradient of the linear approximation. The data of the results of experiments when drilling compacted loam with a drilling tool are given. It is concluded that it is more expedient to drill thawed soils at high rotational frequencies of the drilling tool and feed forces in the range of 1200 – 1700 kgf. The increased rotational speed of the drilling tool also provides the best conditions for transporting destroyed soil from the bottom of wells

Texte intégralRésumé :
The landscapes of the Volga region during the Holocene underwent changes associated with climate fluctuations, a change in the direction of soil-forming processes, and an intensification of anthropogenic activity. The nature of the soil cover also changed - in the chestnut soils prevailing in the region in the late Holocene, the processes of salinization and alkalinization began to appear gradually and with varying intensity. In the Middle Ages, a favorable climate and fertile soils were one of the factors that led to the flourishing of the cities of the Golden Horde in the Volga region. One of them is the commercial city of Beljamen (now the village of Dubovka). With the beginning of the Little Ice Age, the deterioration of the soil began, and at the same time the Volga Germans came to the territory of the region, whose settlements are now partially abandoned (the village of Galka, the village of Shcherbakovka). The next stage in the transformation of landscapes was the construction of reservoirs on the Volga, which caused flooding of many lands and villages, landslides and degradation of soil and water conditions. At present, dry steppes with chestnut, saline and saline soils prevail in the Volga region (the village of Nizhnyaya Bannovka), which are not always favorable for agriculture, and many settlements are abandoned.

Dans ASME 2014 33rd International Conference on Ocean, Offshore and Arctic Engineering. American Society of Mechanical Engineers, 2014. http://dx.doi.org/10.1115/omae2014-23476.
Texte intégralRésumé :
Previously published finite element analysis of drag anchors only involved the pullout capacity of the anchor. There are no finite element (FE) simulations of the installation of drag anchors probably because of two restrictions. First, during the anchor installation, the installation line is needed, which is difficult to be simulated in the FE analysis. Second, the anchor installation that involves large deformation of surrounding soils can not be solved using the classical FE method. In the present work, the installation line is constructed by connecting cylindrical units with each other using connector elements. Then it is introduced into the installation of drag anchors, which is simulated by a large deformation finite element analysis using the coupled Eulerian-Lagrangian (CEL) technique. By comparing with theoretical solutions, including the tension and profile of the installation line embedded in soils, and the movement direction, drag force, drag angle and trajectory of the anchor, the FE simulation of the drag anchor installation is well verified. The present study also demonstrates that the CEL technique is effective for simulating the anchor-line-soil interactional problems.

Texte intégralRésumé :
We investigate the constitutive response of two-dimensional packed samples of polygons using molecular dynamics simulation. The incremental elasto-plastic response is examined in the pre-failure regime. Besides the Young modulus and the Poisson ratio, an additional parameter must be included, which takes into account the anisotropy of the elastic response. The plastic deformations are described by the introduction of the yield and the flow directions. These directions do not agree, which reproduces the non-associated feature of realistic soils. In order to detect the yield surface, different loading-unloading-reloading tests were performed. During the reload path, it is found that the yielding develops continuously with the amplitude of loading, which does not allow to identify a purely elastic regime.

Pile Stability Analysis in Soft or Loose Soils : Guidance on Foundation Design Assumptions with Respect to Loose or Soft Soil Effects on Pile Lateral Capacity and Stability. Purdue University, 2022. http://dx.doi.org/10.5703/1288284317387.
Texte intégralRésumé :
The design of laterally loaded piles is often done in practice using the p-y method with API p-y curves representing the behavior of soil at discretized points along the pile length. To account for pile-soil-pile interaction in pile groups, AASHTO (2020) proposes the use of p-multipliers to modify the p-y curves. In this research, we explored, in depth, the design of lateral loaded piles and pile groups using both the Finite Element (FE) method and the p-y method to determine under what conditions pile stability problems were likely to occur. The analyses considered a wide range of design scenarios, including pile diameters ranging from 0.36 m (14.17 inches) to 1.0 m (39.37 inches), pile lengths ranging from 10 m (32.81 ft) to 20 m (65.62 ft), uniform and multilayered soil profiles containing weak soil layers of loose sand or normally consolidated (NC) clay, lateral load eccentricity ranging from 0 m to 10 m (32.81 ft), combined axial and lateral loads, three different pile group configurations (1×5, 2×5, and 3×5), pile spacings ranging from 3 to 5 times the pile diameter, two different load directions (“strong” direction and “weak” direction), and two different pile cap types (free-standing and soil-supported pile caps). Based on the FEA results, we proposed new p-y curve equations for clay and sand. We also examined the behavior of the individual piles in the pile groups and found that the moment applied to the pile cap is partly transferred to the individual piles as moments, which is contrary to the assumption often made that moments are fully absorbed by axial loads on the group piles. This weakens the response of the piles to lateral loading because a smaller lateral pressure is required to produce a given deflection when moments are transferred to the head of the piles as moments. When the p-y method is used without consideration of the transferred moments, unconservative designs result. Based on the FEA results, we proposed both a new set of p-multipliers and a new method to use when moment distribution between piles is not known, using pile efficiency instead to calculate the total capacity of pile groups.

Texte intégralRésumé :
This report describes activity conducted in several lines of research associated with field-scale water and solute processes. A major effort was put forth developing a stochastic continuum analysis for an important class of problems involving flow of reactive and non reactive chemicals under steady unsaturated flow. The field-scale velocity covariance tensor has been derived from local soil properties and their variability, producing a large-scale description of the medium that embodies all of the local variability in a statistical sense. Special cases of anisotropic medium properties not aligned along the flow direction of spatially variable solute sorption were analysed in detail, revealing a dependence of solute spreading on subtle features of the variability of the medium, such as cross-correlations between sorption and conductivity. A novel method was developed and tested for measuring hydraulic conductivity at the scale of observation through the interpretation of a solute transport outflow curve as a stochastic-convective process. This undertaking provided a host of new K(q) relationships for existing solute experiments and also laid the foundation for future work developing a self-consistent description of flow and transport under these conditions. Numerical codes were developed for calculating K(q) functions for a variety of solute pulse outflow shapes, including lognormal, Fickian, Mobile-Immobile water, and bimodal. Testing of this new approach against conventional methodology was mixed, and agreed most closely when the assumptions of the new method were met. We conclude that this procedure offers a valuable alternative to conventional methods of measuring K(q), particularly when the application of the method is at a scale (e.g. and agricultural field) that is large compared to the common scale at which conventional K(q) devices operate. The same problem was approached from a numerical perspective, by studying the feasibility of inverting a solute outflow signal to yield the hydraulic parameters of the medium that housed the experiment. We found that the inverse problem was solvable under certain conditions, depending on the amount of noise in the signal and the degree of heterogeneity in the medium. A realistic three dimensional model of transient water and solute movement in a heterogeneous medium that contains plant roots was developed and tested. The approach taken was to generate a single realization of this complex flow event, and examine the results to see whether features were present that might be overlooked in less sophisticated model efforts. One such feature revealed is transverse dispersion, which is a critically important component in the development of macrodispersion in the longitudinal direction. The lateral mixing that was observed greatly exceeded that predicted from simpler approaches, suggesting that at least part of the important physics of the mixing process is embedded in the complexity of three dimensional flow. Another important finding was the observation that variability can produce a pseudo-kinetic behavior for solute adsorption, even when the local models used are equilibrium.

Texte intégralRésumé :
The overall objectives of the project were: (a) To measure and study in situ the effect of irrigation with reclaimed sewage effluents on redox processes and related chemical dynamics in soil profiles of agricultural fields. (b) To study under controlled conditions the kinetics and equilibrium states of selected processes that affect redox conditions in field soils or that are effected by them. Specifically, these include the effects on heavy metals sorption and desorption, and the effect on pesticide degradation. On the basis of the initial results from the field study, increased effort was devoted to clarifying and quantifying the effects of plants and water regime on the soil's redox potential while the study of heavy metals sorption was limited. The use of reclaimed sewage effluents as agricultural irrigation water is increasing at a significant rate. The relatively high levels of suspended and, especially, dissolved organic matter and nitrogen in effluents may affect the redox regime in field soils irrigated with them. In turn, the changes in redox regime may affect, among other parameters, the organic matter and nitrogen dynamics of the root zone and trace organic decomposition processes. Detailed data of the redox potential regime in field plots is lacking, and the detailed mechanisms of its control are obscure and not quantified. The study established the feasibility of long-term, non-disturbing monitoring of redox potential regime in field soils. This may enable to manage soil redox under conditions of continued inputs of wastewater. The importance of controlling the degree of wastewater treatment, particularly of adding ultrafiltration steps and/or tertiary treatment, may be assessed based on these and similar results. Low redox potential was measured in a field site (Site A, KibutzGivat Brenner), that has been irrigated with effluents for 30 years and was used for 15 years for continuous commercial sod production. A permanently reduced horizon (Time weighted averaged pe= 0.33±3.0) was found in this site at the 15 cm depth throughout the measurement period of 10 months. A drastic cultivation intervention, involving prolonged drying and deep plowing operations may be required to reclaim such soils. Site B, characterized by a loamy texture, irrigated with tap water for about 20 years was oxidized (Time weighted average pe=8.1±1.0) throughout the measurement period. Iron in the solid phases of the Givat Brenner soils is chemically-reduced by irrigation. Reduced Fe in these soils causes a change in reactivity toward the pesticide oxamyl, which has been determined to be both cytotoxic and genotoxic to mammalian cells. Reaction of oxamyl with reduced-Fe clay minerals dramatically decreases its cytotoxicity and genotoxicity to mammalian cells. Some other pesticides are affected in the same manner, whereas others are affected in the opposite direction (become more cyto- and genotoxic). Iron-reducing bacteria (FeRB) are abundant in the Givat Brenner soils. FeRB are capable of coupling the oxidation of small molecular weight carbon compounds (fermentation products) to the respiration of iron under anoxic conditions, such as those that occur under flooded soil conditions. FeRB from these soils utilize a variety of Fe forms, including Fe-containing clay minerals, as the sole electron acceptor. Daily cycles of the soil redox potential were discovered and documented in controlled-conditions lysimeter experiments. In the oxic range (pe=12-8) soil redox potential cycling is attributed to the effect of the daily temperature cycle on the equilibrium constant of the oxygenation reaction of H⁺ to form H₂O, and is observed under both effluent and freshwater irrigation. The presence of plants affects considerably the redox potential regime of soils. Redox potential cycling coupled to the irrigation cycles is observed when the soil becomes anoxic and the redox potential is controlled by the Fe(III)/Fe(II) redox couple. This is particularly seen when plants are grown. Re-oxidation of the soil after soil drying at the end of an irrigation cycle is affected to some degree by the water quality. Surprisingly, the results suggest that under certain conditions recovery is less pronounced in the freshwater irrigated soils.

Texte intégralRésumé :
Original objectives: The long-term goal of the proposed research is to elucidate the transcription factors, genes and metabolic networks involved in carbon metabolism and partitioning in response to water deficit. The proposed research focuses on the GTLcalcium/calmodulinbindingTFs and the gene and metabolic networks modulated by these TFs in Arabidopsis thaliana. The specific objectives are as follows. Objective-1 (USA): Physiological analyses of GTL1 loss- and gain-of-function plants under water sufficient and drought stress conditions Objective 2 (USA / Israel-TAU): Characterizion of GTL target genes and bioinformatic analysis of data to eulcidate gene-network topology. Objective-3 (Israel-TAU): Regulation of GTLmediated transcription by Ca²⁺/calmodulin: mechanism and biological significance. Objective-4 (Israel-BGU): Metabolic networks and carbon partitioning in response to drought. Additional direction: In the course of the project we added another direction, which was reported in the 2nd annual report, to elucidate genes controlling drought avoidance. The TAU team has isolated a few unhydrotropic (hyd) mutants and are in the process of mapping these mutations (of hyd13 and hyd15; see last year's report for a description of these mutants under salt stress) in the Arabidopsis genome by map-based cloning and deep sequencing. For this purpose, each hyd mutant was crossed with a wild type plant of the Landsberg ecotype, and at the F2 stage, 500-700 seedlings showing the unhydrotropic phenotype were collected separately and pooled DNA samples were subkected to the Illumina deep sequencing technology. Bioinformatics were used to identify the exact genomic positions of the mutations (based on a comparison of the genomic sequences of the two Arabidopsis thaliana ecotypes (Columbia and Landsberg). Background: To feed the 9 billion people or more, expected to live on Earth by the mid 21st century, the production of high-quality food must increase substantially. Based on a 2009 Declaration of the World Summit on Food Security, a target of 70% more global food production by the year 2050 was marked, an unprecedented food-production growth rate. Importantly, due to the larger areas of low-yielding land globally, low-yielding environments offer the greatest opportunity for substantial increases in global food production. Nowadays, 70% of the global available water is used by agriculture, and 40% of the world food is produced from irrigated soils. Therefore, much needs to be done towards improving the efficiency of water use by plants, accompanied by increased crop yield production under water-limiting conditions. Major conclusions, solutions and achievements: We established that AtGTL1 (Arabidopsis thaliana GT-2 LIKE1) is a focal determinant in water deficit (drought) signaling and tolerance, and water use efficiency (WUE). The GTL1 transcription factor is an upstream regulator of stomatal development as a transrepressor of AtSDD1, which encodes a subtilisin protease that activates a MAP kinase pathway that negatively regulates stomatal lineage and density. GTL1 binds to the core GT3 cis-element in the SDD1 promoter and transrepresses its expression under water-sufficient conditions. GTL1 loss-of-function mutants have reduced stomatal number and transpiration, and enhanced drought tolerance and WUE. In this case, higher WUE under water sufficient conditions occurs without reduction in absolute biomass accumulation or carbon assimilation, indicating that gtl1-mediated effects on stomatal conductance and transpiration do not substantially affect CO₂ uptake. These results are proof-of-concept that fine-tuned regulation of stomatal density can result in drought tolerance and higher WUE with maintenance of yield stability. Implications: Accomplishments during the IS-4243-09R project provide unique tools for continued discovery research to enhance plant drought tolerance and WUE.

Texte intégralRésumé :
This report presents results of upland vegetation and soil monitoring of semi-arid grasslands at three Parks by the Southern Colorado Plateau Inventory and Monitoring Network (SCPN) from 2007?2021. The purpose is to compare and contrast five grassland ecological sites and examine how they have changed during the first 15 years of monitoring. Crews collected data on composition and abundance of vegetation, both at the species level and by lifeform (e.g., perennial grass, shrub, forb) and soil aggregate stability and soil texture at 150 plots within five target grassland/shrubland communities delineated using NRCS ecological site (ecosite) classification (30 plots per ecosite). Soils in plots at Petrified Forest NP and Chaco Culture NHP were deeper than those at Wupatki NM. Undifferentiated soil crust comprised the largest component of the soil surface, except at Wupatki where surface gravel dominated. Cover of biological soil crust (cyanobacteria, lichen, and moss) was low. Soil aggregate stability was moderate. From 2007?2021, SCPN crews identified 283 unique plant species. Overall live foliar cover ranged from 12-24%. Four of five ecological sites were dominated by C4 grass species (>70% of total live foliar cover). Shrubs co-dominated at one site (WUPA L) and forbs were an overall small component of total vegetation cover but contributed most of the diversity in these sites. Less than 4% of species detected were nonnative. Russian thistle (Salsola tragus) was the most frequently sampled nonnative, occurring in > 50% of plots at Wupatki in the volcanic upland ecological site. Cheatgrass (Bromus tectorum) was the second most common invasive species but occurred in < 10% of the plots at all ecological sites. Vegetation cover was modeled using Bayesian hierarchical models and included seasonal climatic water deficits, year effects and topographic variables as covariates. Models revealed significant negative time trends (i.e., changes over time that were not explained by changes in seasonal deficit covariates included) in some modeled responses, particularly in the cover of perennial grass at all five ecological sites. Time trends in shrub and forb responses were mixed. Species richness showed variable effects by ecosite, decreasing at CHCU S, and increasing at PEFO S and WUPA V. Modeled responses were influenced by climate covariates, but direction of these effects varied. The most consistent effects were that greater July water stress and higher accumulated growing degree days (i.e., warmer spring temperatures) increased cover of perennial grasses and shrubs during the same year. However, greater water stress in the spring had a negative effect on many responses as expected. Decreasing cover of perennial grass and increasing cover of shrubs and weedy forbs has been predicted for southwestern grasslands in response to increasing aridification due to anthropogenic climate change. Perennial grass trends reported here correspond with these predictions with mixed results on shrub and forb community trends. Continued drought conditions will likely exacerbate negative changes in these systems.

Texte intégralRésumé :
Le Population Council a réalisé une étude sur « les itinéraires thérapeutiques des adolescentes pendant la grossesse, l’accouchement et la période post-partum » dans cinq régions du Burkina Faso. Il s’agissait d’une étude qualitative, exploratoire qui a permis d’identifier et de décrire les itinéraires thérapeutiques des adolescentes en grossesse et post-partum en vue de déceler les obstacles liés à la fréquentation des centres de santé dans le suivi de la grossesse, de l’accouchement assisté et des soins aux nouveau-nés. Les résultats de l’étude montrent que, d’une manière générale, les adolescentes mariées ou non ont recours aux soins traditionnels à domicile par l’utilisation de plantes et/ou décoctions et ne se rendent au centre de santé qu’en cas de non satisfaction. De par l’intérêt et l’engouement de la population enquêtée pour le sujet, il apparaît que le contexte social est favorable à la mise en œuvre d’activités sur la santé reproductive en direction des différents groupes cibles. Les besoins à satisfaire sont réels et manifestes sur le terrain et des actions concrètes sont attendues en vue d’améliorer les conditions de vie des adolescentes, des adolescentes en grossesse et des post-partum.
