Les relations sociétés-natures à la lumière d’un sacrifice. Mémoire locale du développement et pratiques rizicoles en pays Baga Sitem (Guinée)
Résumé : Cet article pose des réflexions sur le thème de la mémoire locale du développement dans le cadre de la riziculture baga sitem en Guinée Maritime. Il s'agit de mettre en avant la mémoire des interventions extérieures en relation avec le contexte environnemental local en identifiant les phases de transformation des pratiques et des changements techniques mis en œuvre par les populations et les projets de développement. Nous partirons de l'exemple d'un sacrifice qui servira d'outil d'analyse pour saisir une part significative de l'histoire rizicole afin de considérer quelques implications sur les relations que les sociétés entretiennent avec les natures et leurs environnements.
Abstract : This essay analyses the local memory of development in the context of Baga Sitem rice-growing on the coast of Guinea. It seeks to highlight the memory of external interventions in relation to the local environment by identifying the stages by which populations and development projects transformed their respective practices and techniques. We begin with an example of a sacrifice which serves as an analytical framework for understanding an important part of the local rice-growing history and its implications for relations between societies and natures
La sexualité des adolescents: quelle évolution ces 40 dernières années?
Le contexte : Pour comprendre la manière dont a évolué la sexualité des adolescents ces dernières décennies, il importe de tenir compte de plusieurs changements sociaux qui ont considérablement modifié le contexte dans lequel les jeunes se développent du point de vue affectif et sexuel.
La famille telle qu’Ariès en a décrit l’avènement au cours du XVIIIème et XIXème siècle cède de plus en plus le pas à une famille nucléarisée voire recomposée(1). Le cadre relativement strict qui prévalait jusque dans les années 60-70 a été remplacé par des modèles éducatifs plus souples et parfois laxistes. L’un des événements majeurs de ces 50 dernières années est sans conteste la «révolution» de mai 68, qui a probablement largement contribué à la libéralisation des comportements sexuels, tant chez les jeunes que chez les adultes. L’éclatement des valeurs véhiculées auprès des jeunes, leur diversité placent ces derniers devant des choix qu’ils n’avaient pas à faire autrefois. Dans un contexte social favorisant l’hédonisme et le plaisir, les jeunes doivent développer leurs propres croyances, attitudes et standards face à leur sexualité
La sexualité à l’ère numérique : les adolescents et le sexting
Bien que la recherche commence à s’intéresser au sexting par rapport aux taux de prévalence et que des campagnes de prévention aient été créées pour cette problématique, des recherches plus approfondies sont nécessaires afin de comprendre tous les enjeux entourant la pratique chez les jeunes, particulièrement lorsqu’elle entraine des conséquences négatives.
Nos questions de recherche sont les suivantes :
Quelles sont les différents éléments qui définissent le sexting du point de vue des jeunes, des parents et des enseignants ? Quelle est la définition du sexting ?
Quelles sont les raisons qui peuvent motiver une personne à pratiquer le sexting (en termes d’envoi et de réception) mais aussi à transférer le contenu à d’autres personnes ?
Quels sont les risques, conséquences et réactions possibles, notamment en termes de jugement ?
Est-ce que la prévention relative au sexting est utile ? Que pourrait-on faire pour prévenir
Tobacco and cannabis use trajectories from adolescence to young adulthood
The main objective of this longitudinal research is to answer the following question: What is the relationship between tobacco and cannabis use trajectories from adolescence to young adulthood?
And more specifically we are interested in:
A. If the use of one of the substances (tobacco or cannabis) decreases overtime, does the use of the other one increase to compensate? Are other substances (such as alcohol, for example) also used to compensate in these cases?
B. Does the probability to become a tobacco smoker increase when cannabis use is heavier or has lasted longer?
C. What are the risk and protective factors that can predict that the use of tobacco and/or cannabis will increase or decrease overtime
Who Are Those Youths Who Consider Themselves as Unpopular?
Purpose: To examine the characteristics of adolescents and young adults (AYA) who perceive themselves as unpopular with peers from the same-sex, opposite-sex, or both.
Methods: We used the baseline wave (2014-15; N¼5179) of the Generation FRee longitudinal study, gathering a cantonal representative sample of in-school 15-24 year-olds. The web-based in school administered questionnaire included the 2 items “Among same-sex/opposite-sex peers, I am very popular” (yes/no). Respondents were divided into 4 groups: Those who perceived themselves as popular with same-sex and opposite-sex peers (POP; N¼3’164, 61.09%); as unpopular with same-sex and opposite-sex peers (UNPOP; N¼1’228, 23.71%); as unpopular with same-sex peers only (UNPOPSame; N¼284, 5.48%), and as unpopular with opposite-sex peers only (UNPOPOther; N¼503, 9.72%). At the bivariate level, groups were compared on sociodemographic data, making same-sex and opposite-sex friends easily, emotional well-being, school performance and track, and substance use (current smoking, past 30-days e-cigarette, cannabis, and alcohol misuse, and other illegal drug use ever). All significant variables (p<.05) were included in a multinomial logistic regression using POP as the reference category. Data are presented as Relative Risk Ratios (RRR) with 95% confidence intervals
Living With a Chronic Condition and Risk Behaviors
Purpose: To assess whether living with a chronic condition (CC) is associated with risk behaviors among youths.
Methods: Data were drawn from the baseline wave (2014-15; N¼5179) of the GenerationFRee survey, a longitudinal study among post-mandatory youths aged 15-24 years in Fribourg, Switzerland. Students were divided into three groups depending on whether they reported having a CC or not: healthy controls (no CC: N¼4529; 46.2% females), CC without limitation (CCWL: N¼536; 52.6% females) and CC limiting daily activities (CCLDA: N¼114; 58.9% females). At the bivariate level groups were compared on sociodemographic data and six risk behaviors (current smoking; current (at least once in the past 30 days) alcohol misuse, cannabis use and use of other illegal drugs; violent behavior and antisocial behavior at least once in the past 12 months). In a second step, a multinomial logistic regression was conducted including all variables significant at the .05 level. Results are given as Relative Risk Ratios (RRR) with 95% confidence intervals
Is Internet use unhealthy? A cross-sectional study of adolescent Internet overuse.
OBJECTIVE: To assess whether problematic internet use is associated with somatic complaints and whether this association remains when checking for internet activity among a random sample of adolescents living in the canton of Vaud, Switzerland.
METHODS: Cross-sectional survey of 3,067 8th graders (50.3% females) divided into average (n = 2,708) and problematic (n = 359) Internet users and compared for somatic complaints (backache, overweight, headaches, musculoskeletal pain, sleep problems and sight problems) controlling for sociodemographic and internet-related variables. Logistic regressions were performed for each complaint and for all of them simultaneously controlling variables significant at the bivariate level.
RESULTS: At the multivariate level, when taken separately, problematic internet users were more likely to have a chronic condition (adjusted odds ratio [aOR] with 95% CI: 1.58 [1.11:2.23]) and to report back pain (aOR: 1.46 [1.04:2.05]), overweight (aOR: 1.74 [1.03:2.93]), musculoskeletal pain (aOR: 1.36 [1.00:1.84]) and sleep problems (aOR: 2.16 [1.62:2.88]). When considered in the full model, only sleep problems remained significant (aOR: 2.03 [1.50:2.74]).
CONCLUSIONS: Our results confirm that problematic internet users report health problems more frequently, with lack of sleep being the most strongly associated and seeming to act as mediator regarding the other ones. Clinicians should remember to screen for excessive internet use their patients complaining of sleep-related problems, back or musculoskeletal pain or overweight. Clinicians should advise parents to limit the amount of time their adolescent children can spend online for leisure activities. Furthermore, limiting the number of devices used to connect to the internet could help warrant enough sleeping time
From controlling to letting go : what are the psychosocial needs of parents of adolescents with a chronic illness?
While one of the main objectives of adolescence is to achieve autonomy, for the specific population of adolescents with a chronic illness (CI), the struggle for autonomy is accentuated by the limits implied by their illness. However, little is known concerning the way their parents manage and cope with their children's autonomy acquisition. Our aim was to identify the needs and preoccupations of parents of adolescents with CI in coping with their children's autonomy acquisition and to determine whether mothers and fathers coped differently. Using a qualitative approach, 30 parents of adolescents with CI participated in five focus groups. Recruitment took place in five specialized pediatric clinics from our university hospital. Thematic analysis was conducted. Transcript analyses suggested four major categories of preoccupations, those regarding autonomy acquisition, giving or taking on autonomy, shared management of treatment and child's future. Some aspects implied differences between mothers' and fathers' viewpoints and ways of experiencing this period of life. Letting go can be hard for the father, mother, adolescent or all three. Helping one or the other can in turn improve family functioning as a whole. Reported findings may help health professionals better assist parents in managing their child's acquisition of autonomy
Disordered Eating: The Young Male Side.
Disordered eating (DE) is known to predominate among girls, and historically studies have focused primarily on them. This cross-sectional study aimed to investigate the characteristics of adolescent and young adult males at risk of DE. Participants (N = 2269; 15-24 years) in a study assessing their lifestyle were divided into two groups based on the SCOFF five-question screening tool: a SCOFF[+] group for participants at risk of disordered eating, and a SCOFF[-] group for everyone else. SCOFF[+] participants were more likely to be overweight and obese; have a lower socio-economic status and non-Swiss parents; experience weight issues; and report a chronic condition, poorer emotional well-being and a less positive attitude towards life. With 10% of males at risk of DE, clinicians should be aware of their specific characteristics, which should be considered red flags. DE is no longer a female-specific issue
Daily internet time: towards an evidence-based recommendation?
Since 2001, a recommendation of no more than 2 h per day of screen time for children 2 years of age or older was adopted in many countries. However, this recommendation was rarely examined empirically. The goal of the present study was to question this recommendation in today's connected world.
We used data from the [email protected] survey (spring 2012), a representative sample of 8th graders in the Canton of Vaud, Switzerland (n = 2942, 50.6% female). Internet use, health outcomes, substance use, well-being and socio-demographic characteristics were considered. Bi-variate statistical analyses were performed.
All outcomes were significantly associated with the time spent on internet, more time being associated with a higher prevalence of adverse consequences. Youth spending on average one more hour on Internet per day than the reference category (1.5-2.5 h) did not differ in terms of adverse health outcomes. Differences began to appear on sleeping problems, tobacco use, alcohol misuse, cannabis use and sport inactivity with youth spending between 3.5 h and 4.5 h per day on internet.
This study demonstrates the absence of justification for setting a limit to only 2 h of screen time per day. Significant effects on health seem to appear only beyond 4 h per day and there may be benefits for those who spend less than an hour and a half on internet
