Tuberculose: conhecimentos, representações sociais e experiências da doença na visão do portador

Tuberculosis is considered one of the most ancient human diseases, cases were registered 3900 years before Christ, and it is currently regarded as a serious public health problem in the world due to several factors such as income mismanagement, precarious standard of life and some sort of prejudice comprised by the word tuberculosis. Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Saúde da Família (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope

A palavra cantada nos espaços intersubjetivos de um centro de atenção psisossocial do município do Natal/RN

The psychiatric care and mental health are undergoing constant change over the History. The Brazilian Psychiatric Reform, which brings up the deinstitutionalization as a structuring in the restorative care process. The Reform has as one of the mainly substitutive services the Centers for Psychosocial Care (CAPS), which work from the Singular Therapeutic Project (PTS) in order to restore the autonomy and restore the dignity of users. The therapeutic workshop is some of the resources used and work several kinds of activities as: writing, handcraft, music, poetry, and so forth. This study set up to apprehend the social representations of helping of the music workshop carried out in the CAPS II east of Natal/RN, from the reports given by the participants of the workshop, using the focal group as technique. This is a descriptive exploratory study with a qualitative approach. A total of 16 users participated in four musical therapeutic workshops from April to May 2010. The study was approved by the Ethics and Research Committee of UFRN. The discursive material from the workshop was submitted to the informational resource of Analyse Lexicale par Contexte d um Ensemble de Segments de Texte, ALCESTE, and analyzed based on the Theory of Representations and the Central Core Theory. The majority of subjects were men (62.5%), single (62.5%), aged 40-49 years (37.6%) and elementary school level (56.2 %). The reports were transcribed and submitted to the classification system of ALCESTE, which elected the following categories: Category 1 - Experience in the Word Family Sung, Category 2 - Musical Experiences and Approaches, and Category 3 - Feelings and emotions evoked by music. The representation of these individuals is anchored in the experience they have with the CAPS, lived and socialized by common sense, through this particular social group workshop objectified in music therapy as a therapeutic modality enjoyable. The central core revealed the intrinsic relationship between users and the music, establishing a relationship of openness to use the same while its therapeutic use in workshops of substitute services for mental health. Peripherals elements issues are related to listen, share and experience music in the family. Intermediary Elements relate to the feelings and emotions evoked by music, given her close relationship with it. It was found in the study that music can be construed as an artifact of good therapeutic responsiveness to users, configuring it as an invigorating and enjoyable therapy, confirming the need for continuity of this activity, as well as its expansion into the service

Comportement thermique des géopolymères obtenus à partir d'une argile kaolinite

The aim of this work is to study the thermal behavior of geopolymers derived from kaolinite (clay). The geopolymers were characterized by various technics: Thermal analysis (DTA, TGA and dilatometer), X-ray diffractography (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Certain physical properties of the products were equally determined: linear shrinkage of curing, percentage of water absorption and compressive strength. The results obtained after drying and thermal treatment showed that the products preserved their initial forms, but showed variable colours based on the temperatures they were treated at. The products obtained at 90, 300 and 500 °C contained hydroxysodalite. The synthesis of geopolymers is not complete at 300 °C (presence of kaolinite in the material) but the products obtained are quite consolidated. The geopolymers obtained have weak values of linear shrinkage of curing (less than 0.6 %) and the compressive strength increases from room temperature (4.9 Mpa) up to 400 °C (8.9 MPa) then becomes constant between 400 and 500 °C. The combination of results demonstrates the efficiency of the temperature parameter during the synthesis of geopolymers based on kaolinite. // L’objet de ce travail est l’étude du comportement thermique des géopolymères à base d’une argile kaolinite. Les produits obtenus ont été caractérisés au moyen de plusieurs techniques : analyses thermiques (ATD, ATG et dilatométrie), microscopie électronique à balayage (MEB), analyse par diffraction de rayons X (DRX), analyse infrarouge par transformée de Fourier (IRTF). Certaines propriétés physiques des produits obtenus ont également été déterminées : retrait linéaire de cuisson, pourcentage d’absorption d’eau et résistance à la compression. Les résultats obtenus montrent qu’après le séchage et à la fin du traitement thermique, les éprouvettes des produits conservent leur forme initiale mais présentent une variation de couleur en fonction de la température de traitement. Les produits obtenus à 90, 300 et 500 °C contiennent de l’hydroxysodalite. La réaction de synthèse géopolymère n’est pas encore terminée au moins à 300 °C (présence de kaolinite dans le matériau) mais les produits obtenus sont assez consolidés. Les géopolymères obtenus présentent de faibles valeurs de retrait linéaire de cuisson (inférieure à 0,6 %) et une résistance à la compression qui augmente de la température ambiante (4,9 MPa) jusqu’à 400 °C (8,9 MPa) puis devient constante entre 400 et 500 °C. L’ensemble de ces résultats permet de mettre en exergue l’efficacité du paramètre « température » au cours de la synthèse des géopolymères à base de kaolinite.

Metabolomics analysis in rats with thiamine deficiency identifies key metabolites in vulnerable brain regions and suggests neural stem progenitor cells play a role in ameliorating metabolic dysfunction

La documentation scientifique fait état de la présence, chez l’adulte, de cellules souches et progénitrices neurales (CSPN) endogènes dans les zones sous-ventriculaire et sous-granulaire du cerveau ainsi que dans le gyrus denté de l’hippocampe. De plus, un postulat selon lequel il serait également possible de retrouver ce type de cellules dans la moelle épinière et le néocortex des mammifères adultes a été énoncé. L’encéphalopathie de Wernicke, un trouble neurologique grave toutefois réversible qui entraîne un dysfonctionnement, voire une défaillance du cerveau, est causée principalement par une carence importante en thiamine (CT). Des observations récentes laissent envisager que les facteurs en cause dans la prolifération et la différenciation des CSPN pourraient également jouer un rôle important lors d’un épisode de CT. L’hypothèse, selon laquelle l’identification de nouveaux métabolites entrant dans le mécanisme ou la séquence de réactions se soldant en une CT pourraient en faciliter la compréhension, a été émise au moyen d'une démarche en cours permettant d’établir le profil des modifications métaboliques qui surviennent en de telles situations. Cette approche a été utilisée pour constater les changements métaboliques survenus au niveau du foyer cérébral dans un modèle de rats déficients en thiamine (rats DT), particulièrement au niveau du thalamus et du colliculus inférieur (CI). La greffe de CSPN a quant à elle été envisagée afin d’apporter de nouvelles informations sur la participation des CSPN lors d’un épisode de CT et de déterminer les bénéfices thérapeutiques potentiels offerts par cette intervention. Les sujets de l’étude étaient répartis en quatre groupes expérimentaux : un premier groupe constitué de rats dont la CT était induite par la pyrithiamine (rats DTiP), un deuxième groupe constitué de rats-contrôles nourris ensemble (« pair-fed control rats » ou rats PFC) ainsi que deux groupes de rats ayant subi une greffe de CSPN, soit un groupe de rats DTiP greffés et un dernier groupe constitué de rats-contrôles (rats PFC) greffés. Les échantillons de foyers cérébraux (thalamus et CI) des quatre groupes de rats ont été prélevés et soumis à des analyses métabolomiques non ciblées ainsi qu’à une analyse visuelle par microscopie à balayage électronique (SEM). Une variété de métabolites-clés a été observée chez les groupes de rats déficients en thiamine (rats DTiP) en plus de plusieurs métabolites dont la documentation ne faisait pas mention. On a notamment constaté la présence d’acides biliaires, d’acide cynurénique et d’acide 1,9— diméthylurique dans le thalamus, alors que la présence de taurine et de carnosine a été observée dans le colliculus inférieur. L’étude a de plus démontré une possible implication des CSPN endogènes dans les foyers cérébraux du thalamus et du colliculus inférieur en identifiant les métabolites-clés ciblant les CSPN. Enfin, les analyses par SEM ont montré une amélioration notable des tissus à la suite de la greffe de CSPN. Ces constatations suggèrent que l’utilisation de CSPN pourrait s’avérer une avenue thérapeutique intéressante pour soulager la dégénérescence symptomatique liée à une grave carence en thiamine chez l’humain.

Perfis e práticas dos profissionais de saúde mental em dois hospitais psiquiátricos de grande porte

In the Brazilian network of psychosocial care, health professionals are important actors in the process of transformation of mental health public policies among various services. In the reality of psychiatric hospitals, one should understand the need to expand the debate about the current context of practices developed. This study aimed at analyzing the process of psychiatric reform and the mental health policy in the State of Rio Grande do Norte (RN) from the profiles and practices of higher-level professionals in two psychiatric hospitals. This is a cross-sectional and descriptive research, with quantitative and qualitative data, conducted in two psychiatric hospitals of RN. The universe of the target population was 95 professionals, taking into account the margin of error of 8%, non-response rate and the inclusion criteria: holding effective link with the institution by means of approval in public examination for, at least, six months, being state or municipal servant; having a minimum weekly workload of 20 hours in service; participating in care and/or activities with patients and families in a direct way. The final sample consisted of 60 professionals. The tool for data collection was a questionnaire with closed and semi-open questions about socioeconomic profile, and mental health policies, practices and training. Quantitative data were tabulated in the statistical software SPSS, and simple and bivariate statistics, chi-square type, was used for analysis by adopting the significance level with the value p<0,05. In order to analyze data, the content analysis of Bardin was used. The qualitative findings obtained with the semi-open questions in Analyse Lexicale par Context d'un Ensemble de Segments de Texte (ALCESTE) were grouped into four thematic axes: Professional action in mental health; Mental health training; Scenarios of psychiatric reform and psychiatric hospitals; Mental health policies and practices: challenges for professionals in hospitals. The profile of professionals has revealed the majority of women (89,7%), nurses (36,7%), aged 50-59 years (42,9%), weekly workload of 40 hours (52,4% ), time of completion of graduation from six to 15 years (57%), and 21,4% reported to have specialization in mental health. Regarding the practices developed in individual care, it was found an association between those who do not build or partially conducts the therapeutic project and those who conduct care related to observation and annotation. In family care, it was obtained care consultation during crisis; and, in group care, recreational activities. In the analysis of thematic axes, it was noted that, despite changes identified in the profiles and practices of higher-level professionals in care services for mental health, with the implementation of new public policies for this field, the findings indicate the confluence of asymmetries and divergences in the actions of the teams in psychiatric hospitals, difficulties in managing services, frequent readmissions, reduced quantitative of available services and equipment, high demand of users, disarticulation of the network of psychosocial care, and the very shortage of skilled human resources to compose these services. Accordingly, the evidenced scenarios partially outline the current political and ideological mismatch of the national process of psychiatric reform that denies the role of care actions conducted within hospitals, although it has not gone far enough with the creation of new services that justify the total extinction of this institution

Trajetória de vida dos pescadores vítimas de lesão medular por mergulho: experiências, representações sociais e estresse

Spinal cord injury causes permanent disabling manifestations, affecting the anatomic integrity, bodily changes and functional limitations related to the disability state. It was aimed to analyze the social representation, stress level and experiences of fishermen victims of spinal cord injury caused by diving accident in the Northern beaches of Brazil. It is a descriptive - exploratory study with quantitative, qualitative and representational data developed i n fishermen’s villages in nine beaches of Northern shore/RN, between October 2013 to August 2014, after the approval of the Ethics Committee in Research of the Universidade Federal do Rio Grande do Norte, under the number 431.891/2013, CAAE 20818913.0.0000 .5537. The sample was composed by 44 fishermen with spinal cord injury, defined from inclusion and exclusion criteria of the participants. It was used as instrument to collect the data a semi structured interview. Quantitative data was analyzed by descrip tive statistics, showing the data through table, boxes and graphics by Microsoft Excel. Data from interviews were submitted to the software called Analyse Lexicale par Contexte d’un Ensemble de Segments de Texte (ALCESTE) using the analysis of the Social R epresentation Theory and Center Core Theory. It is shown the outcomes of the research through four articles, following the normative recommendations of the journals. Participants of the study were all male, age mean 49,6 years, elementary school (68,2%), m arried (77,3%); paraplegia sequel (50,0%). Most of them showed stress (75,0%), almost in the exhaustion stage (33,3%), prevalent insomnia symptoms (95,5%) in the last hours; hypertension (97,7%) in the last week and sexual troubles (95,5%) in the last mont h). Decompressive illness caused spinal cord injury (57,1%), occurred prevalently in low summer (75,0%), northern shore (96,4%), having as main consequences the paresthesia and pain in the upper and lower limbs (67,9%), followed by death (25,0%). Interview analysis under the understanding of Social Representation of spinal cord injury allowed the appearance of seven categories: Treatment: limitation and expectative; Spinal Cord injury: before and after; Retirement: reality yet to come; Disability: dependenc y, incapacity, vulnerability; Overcoming and autonomy; Self feelings: physics losses and new start; Life and labor: impediments, plans and changes. The center core of the representation is found in the first category by the expectative and limitation on th e treatment, meanwhile the outskirt elements are in seventh and third categories. Physics limitation for fishing activities and retirement expectative is the most outstanding of the structure. Social representation concerning spinal cord injury is found in a transaction moment between before and after with the prevented fishing activity, coping of the situation with the potential remaining. The anchoring is established in the desire for changes related to the improvements of life and health conditions exper ienced day by day through faith. This study finishes pointing out the range of the objectives, which topic is relevant for public health of fishermen. It is suggested prevention measures, promotion and health recovery of fishermen, besides safe, healthy an d worthy conditions as a compromise of social and health politics.

This study aimed to evaluate the work of professionals to care for families in Psychosocial Care Centers ( C APS) of Rio Grande do Norte ( RN), from the roles and functions performed by these professional services. For this, it was pointed out the following objectives: To describe the profile and the activities conducted by mental health teams in the RN CAPS ; Know the opinion of professionals in the mental health teams of the poli ti c , practices and training in mental health; Check the suitability of the roles and functions of professionals working in the RN CAPS in relation to care for families . This is an analytic al cross - sectional study of quantitative and qualitative approach . Data were c ollected through a questionnaire in 33 CAPS RN, between March and October 2014 , after being approved by the Research Ethics Committee / UFRN , opinion nº217.808 , CAAE : 10650612.8. 1001.5537 , on March 1 2013. T he sample was adopted , defined by inclusion and exclusion criteria , and is composed of 183 professionals. The database preparation followed two steps: 1. Preparation and processing of data of closed questions of the questionnai re concerning the characterization and practices in mental health research subjects through informational resource Statistical Package for Social Scienses (SPSS) Statistics version 20.0 ; 2. To check the significance level was chosen by applying the chi - squ are test. Preparation and treatment of the corpus formed by the answers to open questions relating to the policies, practices and training in psychiatry through Analyse lexicale pair Contexte software d' un Ensemble of Segments of Texte ( ALCESTE) together a nd categorized by content analysis technique , Bardin (2004) . The data analysis is supported in the literature . It m ade explicit the results through three articles waxing the following results. In the first, participants profile was characterized by a predo minance of females (76.5 %), aged 40 - 58 years ( 61.7 %). They work between 30 and 40 hours per week (63.5 %), working in mental health for over 10 years ( 98.4%). The sample directs the care of family groups ( 65.7%), predominantly the care team of social worke rs, nurses, psychologists and occupational therapists . The doctor performs emergency care without interaction with the staff (48.6%) . On the difficulties encountered in services are ranked in : materials and supplies ( 75.1%), financial ( 78.5%) and structura l ( 66.9%). The second article contains qualitative data organized into five categories : Promoting the rehabilitation of users of CAPS ; Needs training ; Conflicts and satisfactions of teamwork ; Practices developed in CAPS ; Effective difficulties of Mental He alth Policy . The third article highlights the inadequacy of care for families ( 93.4%) and comparing the care families and groups in CAPS both types show to be inadequate : family ( 92.63%), groups ( 92, 60%). The main data obtained reveal the urgent need for transformation in psychosocial care . It shows also the importance of investments in inputs, physical structure and training of human resources for the CAPS.

A reforma psiquiátrica e a política de saúde mental do Rio Grande do Norte: papéis e funções de profissionais e gestores

This study arose from an interest in knowing the reality of mental health care in Rio Grande do Norte (RN) on the advances and challenges in the intersectoral agreements paths and consolidation of the Psychosocial Care Network (RAPS) from the state. Considering problematic and concerns were defined as objectives: Identify the knowledge of managers of Rio Grande do Norte on the National Mental Health Policy (PNSM) in the RN State; Describe the activities developed by health professionals in the individual service offered in the CAPS from RN; Understanding the relationship of managers’ knowledge on national mental health policy in professionals’ practice working in the the CAPS from the countryside. It is a descriptive study with a quantitative and qualitative approach, carried out in 30 CAPS from RN’s countryside, where 183 professionals answered a structured questionnaire with closed questions about the activities they do in individual care; and 19 mental health coordinators of municipalities and the state coordinator of RAPS were interviewed about their knowledge on the Mental Health Policy. Data were collected after approval by the Research Ethics Committee of the Federal University of Rio Grande do Norte, with the number 508.430 CAAE: 25851913.7.0000.5537 from August through October of 2014 in 26 municipalities with CAPS from the state. Quantitative data were tabulated and analyzed using a descriptive statistics aided by the software Statistical Package for the Social Scienses (SPSS) version 20.0. The qualitative data were prepared in a corpus and analyzed through software Analyse Lexicale par Contexte d’um Ensemble de Segments de Texte (ALCESTE) that allow to perform textual statistical analysis and categorization from their comments, submitted to Bardin content analysis. Five categories were generated approaching the managers’ knowledge, namely: Back to society: leadership and users’ role and autonomy; The gap between policy and practice; Barriers that affect the service; Structuring the Psychosocial Care Network; Multidisciplinary team: attribuitios and activities. The CAPS professionals’ ages ranged from 20 to 58 years, prevailing females, with 76.5% of the total, the majority were social workers (16.8%), psychologists (15.3%), nurses (14.8%) and nursing technicians (14.8%). The results showed precariousness in care associated with physical workload regard to high workload and low wages of the CAPS professionals' and, also, it was possible to observe a large involvement of professionals in care delivery, despite the difficulties encountered in services. It was found little knowledge in managers regarding the National Mental Health Policy having as causes of this reality the poor education and training of these professionals. The responses of professionals working in care reveals strong consistency with what is expected of a psychosocial care service. Points up as a thesis of this study that the psychiatric reform and mental health policy in Rio Grande do Norte is following a structural expansion process, but with precariousness of services from a still unprepared management to act in a psychosocial context.

Representações sociais de familiares sobre o atendimento das emergências psiquiátricas

The reformist movements in the field of mental health have pointed battle flags, among which the prioritization of production of mental health care out of the asylum environment should be highlighted, aiming the reduction of psychiatric beds, greater control over the hospitalization, family co-participation and the rescue of the citizenship of the social players involved. With the progressive reduction of asylum beds, associated with a lot of structural problems in the health services, the occurrence of crises outside the hospital environment has been increasingly frequent, thus giving the family an important therapeutic role. In face of this scenario, there is an urgent need to understand the social construction of the care for psychiatric emergencies, identifying the meanings assigned by family members to their constituent aspects. This study seeks to answer the following research question: what are the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte? Therefore, the aim is to analyze the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte. This is an exploratory and descriptive study, with a mixed approach, making use of multimethods: for collection, the semi-structured interview and the Technique of Free Association of Words; for data analysis, the Thematic Analysis of Bardin and its steps was used, with the informational support of the softwares ALCESTE (Analyse Lexicale par Contexte d'un Ensemble de Segments de Texte) and Iramuteq (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires); and the theoretical support of social representations. The study participants totaled 72, and they were selected from the following criteria: older than18 years, with degree of kinship with users suffering from some mental and behavioral disorder, and who have already witnessed a situation of crisis, rescued by the SAMU or other means and taken to the psychiatric hospital or general emergency room. Preliminary results point out: 1.Previous note of the research project with the aim to disseminate it in the scientific community and ensure the intellectual property of the work; 2.The contextual analysis of the care for emergencies in the study place. Reflection about the phenomenon provide a name to the care for the psychiatric emergencies, which is called immediate context; the technical and operational aspects that influence the care, as a specific/ general context; and mental health policies in Brazil are identified as metacontext; 3. The systematic review from randomized clinical trials in the databases PubMed, COCHRANE, LILACS, SciELO and SCIRUS, with the use of the descriptors: ‘Physical restraint’, ‘Psychiatric emergency services’, ‘Restraint’, ‘Physical and Emergency Services’, ‘Psychiatric’. Only one work met the search protocol criteria: a short-term essay that records limited results about the proportion of people who are in restraint and seclusion. It does not show statistically significant results in relation to indications, contraindications and risks of the use of physical restraint; 4. The social representations of the care for psychiatric emergencies. The study results point to the presence of five thematic categories: 1. feeling in the face of the crisis/care; 2. thoughts and perspectives about the crisis/care; 3. centrality of care in the medical- medication-hospitalization triad; 4. the thinking/acting in the face of the use of physical restraint and police force; 5. periodicity of crises. The central core of the representation is in the first category, whilst the peripheral elements are in the third and fifth categories. The contrast zone is in the second and fourth categories. The sadness is the most prominent element of the structure. The social representations about the care for psychiatric crises are at a time of transition between the hegemonic and reformist models, with the traditional aspects being predominant, but already showing peripheral and contrast elements that point to a possible change in the representational field.

La pauvreté au masculin: De l'autoréalisation de soi à la "Vie Nue"

À l’origine de la présente thèse, il y a d’abord mes 25 ans d’engagement citoyen au sein du mouvement de lutte contre la pauvreté au Québec, notamment en défense collective des droits des personnes assistées sociales. C’est à travers cet engagement qu’a émergé la question de recherche de cette thèse : existe-t-il un lien entre l’expérience de pauvreté des hommes en situation de pauvreté et leur socialisation de genre? Afin de répondre à cette question de recherche, j’ai utilisé comme données secondaires pour cette thèse, 27 entrevues réalisées en 2006-2007 auprès d’hommes prestataires d’aide sociale par le Centre de recherche de Montréal sur les inégalités sociales, les discriminations et les pratiques alternatives de citoyenneté (CREMIS). Une analyse qualitative par catégories conceptualisantes a été utilisée pour analyser en profondeur 17 de ses 27 entrevues avec comme toile de fond une posture ontologique inspirée de l’approche de conscientisation de Paolo Freire, une posture épistémologique constructiviste, postmoderniste et critique, ainsi qu’un univers théorique et conceptuel inspiré de deux domaines de recherche : celui des études sur la pauvreté et celui des études sur les masculinités. Les résultats de l’analyse des entrevues ont permis d’en arriver aux quatre principaux constats suivants : 1) l’existence d’un lien entre pauvreté et masculinités, notamment l’adhésion des répondants à un certain nombre d’attributs de la masculinité hégémonique, et l’influence de cet idéal de la masculinité sur leur parcours d’autoréalisation de soi, ainsi que sur les stratégies et moyens utilisés pour faire face à différents obstacles; 2) l’inscription du parcours des répondants dans un projet ego-identitaire parsemé d’obstacles difficiles à surmonter pour des hommes appartenant à la classe des travailleurs génériques et disposant d’un capital humain, culturel et social qui, au fil de leur parcours, se détériore, rendant de plus en plus difficile leur projet d’autoréalisation de soi; 3) le constat que l’aide publique, plutôt que d’assurer un filet de protection sociale, punissait les hommes rencontrés en les poussant à la « vie nue » et que l’aide sociale agissait comme un appareil répressif d’État de maintien de l’oppression de l’ordre de genre : 4) la nécessité, pour la pratique du travail social, de développer une aide formelle adaptée aux besoins des hommes en situation de pauvreté en misant sur leur capacité de résilience comme levier d’intervention, mais aussi d’agir sur les causes structurelles de la pauvreté des hommes, notamment de déconstruire la masculinité hégémonique et de revendiquer un meilleur filet de sécurité sociale.

GENETIC EVALUATION OF SEED TRAITS FROM INTRASPECIFIC CROSSING OF GENETICALLY DISTINCT WATERMELON VARIETIES

Citrullus lanatus (Thunb.) Matsumura and Nakai (Cucurbitaceae) is an important cucurbit crop worldwide. Global production of watermelon is about 90 million metric tonnes per annum, making it among the top five most consumed fresh fruits. The objective of this study was to evaluate seed variability in different segregating populations, and determine heritability of traits of watermelon. Interspecific crosses were made between two cultivars of C. lanatus (Bebu and Wlêwlê Small Seeds (WSS) were performed at Research Station of Nangui Abrogoua University in Abidjan, Côte d’Ivoire. There was wide variability between parental, F1, BC1 (first generation of back-crossing) and F2 seeds. Seeds of all hybrid populations were intermediate versus those of the parents. Also, crossing did not affect F1 and F2 seed characters, but affected those of BC1 because of maternal effects. Thus, back-crossing on Bebu cultivar produced seeds which looked like those of Bebu; while back-crossing on WSS cultivar produced seeds similar to those of WSS. Principal Component Analysis (PCA) and individuals repartitioning revealed that Bebu and WSS cultivars were genetically distinct and showed three main groups: two groups from each parental line and one from a recombinant line (hybrids). F2 population had a wide individual’s dispersion, and contained seeds of all other populations. High heritability was observed for all evaluated characters.
