Curriculum sequencing for an e-learning system based on learning styles

This work shows the use of adaptation techniques involved in an e-learning system that considers students' learning styles and students' knowledge states. The mentioned e-learning system is built on a multiagent framework designed to examine opportunities to improve the teaching and to motivate the students to learn what they want in a user-friendly and assisted environment

Cannabis dependence in Swiss adolescents: An exploration of the role of anxiety, coping styles and psychosocial difficulties

This naturalistic cross-sectional study explores how and to what extent cannabis dependence was associated with intrapersonal aspects (anxiety, coping styles) and interpersonal aspects of adolescent functioning (school status, family relationships, peer relationships, social life). A convenience sample of 110 adolescents (aged 12 to 19) was recruited and subdivided into two groups (38 with a cannabis dependence and 72 nondependent) according to DSM-IV-TR criteria for cannabis dependence. Participants completed the State-Trait Anxiety Inventory (STAI-Y), the Coping Across Situations Questionnaire (CASQ), and the Adolescent Drug Abuse Diagnosis (ADAD) interview investigating psychosocial and interpersonal problems in an adolescent's life. Factors associated with cannabis dependence were explored with logistic regression analyses. The results indicated that severity of problems in social life and peer relationships (OR = 1.68, 95% CI = 1.21 - 2.33) and avoidantcoping (OR = 4.22, 95% CI = 1.01 - 17.73) were the only discriminatory factors for cannabis dependence. This model correctly classified 84.5% of the adolescents. These findings are partially consistent with the "self-medication hypothesis" and underlined the importance of peer relationships and dysfunctional coping strategies in cannabis dependence in adolescence. Limitations of the study and implications for clinical work with adolescents are discussed.

Santé et styles de vie des adolescents âgés de 16 à 20 ans en Suisse (2002). SMASH 2002 : Swiss multicenter adolescent survey on health 2002

Le présent rapport décrit les grandes tendances qui se dégagent des résultats de l'Enquête SMASH 2002 et propose quelques hypothèses pour éclairer la compréhension et les enjeux de la situation actuelle ainsi que des pistes de réflexion pour l'avenir. Cette étude repose sur deux approches complémentaires de la santé: l'une donne la primauté aux aspects sociologiques des conduites de santé ("lifestyle"); l'autre, de nature épidémiologique, met l'accent sur la prévalence des comportements et procède à des analyses dans divers sous-groupes ou dans le temps. L'étude SMASH 2002 fournit une photographie de la situation des adolescents et de leur état de santé : besoins et comportements de santé, facteurs associés et évaluation des grands changements intervenus depuis une dizaine d'années. Ces données doivent permettre de réfléchir à une planification optimale des services de soins et des programmes de prévention et de promotion de la santé en faveur des adolescents.

Effects of web-based electrocardiography simulation on strategies and learning styles

OBJECTIVETo identify the association between the use of web simulation electrocardiography and the learning approaches, strategies and styles of nursing degree students.METHODA descriptive and correlational design with a one-group pretest-posttest measurement was used. The study sample included 246 students in a Basic and Advanced Cardiac Life Support nursing class of nursing degree.RESULTSNo significant differences between genders were found in any dimension of learning styles and approaches to learning. After the introduction of web simulation electrocardiography, significant differences were found in some item scores of learning styles: theorist (p < 0.040), pragmatic (p < 0.010) and approaches to learning.CONCLUSIONThe use of a web electrocardiogram (ECG) simulation is associated with the development of active and reflexive learning styles, improving motivation and a deep approach in nursing students.

Coparenting and Toddler's Interactive Styles in Family Coalitions

The current study examined the coparenting and toddler's interactive styles in family coalitions. According to structural family theory, boundaries between generations are clear in alliances, but disturbed in coalitions: the parents look to the child to regulate their conflictual relationship and the child attempts to meet this need. In a normative sample studied longitudinally during the Lausanne Trilogue Play situation (LTP, N=38), 15 coalition cases were detected. Styles of coparenting and of child's interactions were determined and compared in coalition and alliance cases at 18 months. Findings confirm the structural family model by showing the specific ways in which the coparenting and the toddler's interactive styles are associated in 3 different patterns of coalitions: binding, detouring, and triangulation. They illustrate how the child's triangular capacity, or her ability to simultaneously communicate with both parents, is used to regulate the parents' relationship. They suggest that the LTP observational paradigm is a promising assessment method of early family interactions. They point to the importance of assessing early the child's contribution to family coalitions.

Que promettent les styles d'interactions? Une approche sociologique de l'intimité conjugale

This article intends to grasp the stabilization process, deterioration or improvement of the conjugal intimacy over five years, based on a representative sample of couples living in Switzerland. The dynamics develop in different ways depending on the degree of autonomy of the partners, the gendering of household tasks, conjugal openess and the coping strategies of the couples.

Architectural and Functional Similarities between Trimeric ATP-Gated P2X Receptors and Acid-Sensing Ion Channels

ATP-gated P2X receptors and acid-sensing ion channels are two distinct ligand-gated ion channels that assemble into trimers. They are involved in many important physiological functions such as pain sensation and are recognized as important therapeutic targets. They have unrelated primary structures and respond to different ligands (ATP and protons) and are thus considered as two different ion channels. As a consequence, comparisons of the biophysical properties and underlying mechanisms have only been rarely made between these two channels. However, the recent determination of their molecular structures by X-ray crystallography has revealed unexpected parallels in the architecture of the two pores, providing a basis for possible functional analogies. In this review, we analyze the structural and functional similarities that are shared by these trimeric ion channels, and we outline key unanswered questions that, if addressed experimentally, may help us to elucidate how two unrelated ion channels have adopted a similar fold of the pore.

Anxiety and severity of illicit substance use in adolescence: Evaluating the mediating role of perceived coping styles

The purpose of this study was to examine whether coping styles (Active coping, Internal coping and Withdrawal coping) mediated the relationships between anxiety and severity of illicit substance use among a sample of 110 Swiss adolescents ages 12-19 (M=16.3, SD=1.66). The current study tested two competing models of anxiety on severity of illicit substance use. In the first model, we tested the direct effect of trait anxiety (STAI-Y anxiety score) on severity of illicit substance use (ADAD drug use severity rating), while in the second models we examined the mediating role of coping styles in the link between trait anxiety and severity of illicit substance use. Path models indicated that the associations between trait anxiety and severity of illicit substance use are partially mediated by active and withdrawal coping styles. Limitations of the findings and implications for prevention of substance use in adolescence are discussed.
