BackgroundIn addition to plant species biology and ecology, understanding the folk knowledge systems related to the use of plant species and how this knowledge system influences the conservation of plant species is an important issue in the implementation of sustainable strategies of biodiversity conservation programs. This study aimed at providing information on the use and local knowledge variation on Chrysophyllum albidum G. Don a multipurpose tree species widely used in southern Benin.MethodsData was collected through 210 structured interviews. Informants were randomly selected from ten villages. The fidelity level and use value of different plant parts of C. albidum were estimated. The variation in ethnobotanical knowledge was assessed by comparing the use value between ethnic, gender and age groups. In order to assess the use pattern of the different plant parts in folk medicine, a correspondence analysis was carried out on the frequency citation of plant parts.ResultsFour categories of use (food, medicine, firewood and timber) were recorded for C. albidum. With respect to the different plant parts, the fleshy pulp of the African star apple fruit showed high consensus degree as food among the informants. Fifteen diseases were reported to be treated by the different parts of C. albidum in the region. Correspondence analysis revealed the specificity of each part in disease treatment. There was no significant difference among ethnic groups regarding the ethno-botanical use value of C. albidum. However, significant difference existed between genders and among age groups regarding the knowledge of the medical properties of this species.ConclusionsC. albidum is well integrated in the traditional agroforestry system of the southern Benin. Despite its multipurpose character, this species remains underutilized in the region. Considering the current threat of habitat degradation, action is needed in order to ensure the long term survival of the species and local communities’ livelihoods.

Social and familial maladjustment is the inability to conform to a group's habits and norms and to participate in its activities and productions. The purpose of this study is to study the social representations of the social and familial maladjustment of adolescents and young people. This is a case study, using a mixed method essentially qualitative, set in a closed educational center in the Department of Littoral in Benin. The study concerned adolescents and young people admitted to the center and their referents. The respondents in the target population were all male and aged 10 to 23 with an average age of 18 years. The social representations of maladjustment, according to young people and their referents are similar. They concern social disqualification, inadequate educational attitudes, the absence of familial model, educational failure linked to adolescents or young people and mystical-religious representations. Adolescents and young people define themselves as deviants while their referents define them as delinquents. This create an insecurity feeling and a need to protect society. Adults have to integrate themselves earlier in the prevention of this phenomenon with the help and /or child psychiatrist lead.

The developmental path of the minor may be marked by particular situations such as conflicts with the law, various crimes. The situations, contexts and processes that lead to crime are multiple. Thus, the aim of our research was to study the characteristics of minors judged for crime, seen in a judicial space. This was a retrospective, cross-sectional, descriptive study carried out at the Cotonou First Instance Court. Data were collected from the judicial files of minors tried for crime by the juvenile court ruling on criminal matters from 1 January 2011 to 31 December 2015; 34 files were taken into account. The respondents were all adolescents aged between 10 and 18 years. The majority of them were tried for homicide (61.7%) and rape (32.4%). For 35.3% of the minors tried for crime, the relationship with opposite sex parent had poor quality. These minors received a firm prison sentence (88.2%), and 11.8% of them were placed in a foster centre without receiving a prison sentence. Crimes committed by minors calls into question our ability to supervise and provide a safe and appropriate framework for the psychological construction of children and adolescents in our society. Measures should be taken in terms of prevention at various levels to reduce the risk of children developing criminal behaviour.
