Teacher-Child Interaction Training (TCIT), adapted from Parent-Child Interaction Therapy (PCIT), ... more Teacher-Child Interaction Training (TCIT), adapted from Parent-Child Interaction Therapy (PCIT), is a classroom-based program designed to provide teachers with behavior management skills that foster positive teacher-student relationships and to improve student behavior by creating a more constructive classroom environment. The purpose of this pilot study was to evaluate TCIT in more classrooms than previously reported in the literature, with older children than previously reported, using random assignment of classrooms to TCIT or to a no-TCIT control condition and conducting all but two sessions within the classroom to enhance feasibility. Participants included 11 kindergarten and first grade classroom teachers and their 118 students from three urban, public schools in Manhattan, with five classrooms randomly assigned to receive TCIT and six to the no-TCIT control condition. Observations of teacher skill acquisition were conducted before, during, and after TCIT for all 11 teachers, and teacher reports of student behavior were obtained at these same time points. Teacher satisfaction with TCIT was assessed following training. Results suggested that after receiving TCIT, teachers increased rates of positive attention to students' appropriate behavior, decreased rates of negative attention to misbehavior, reported significantly less distress related to student disruptive behavior, and reported high satisfaction with the training program. Our study supports the growing evidence-base suggesting that TCIT is a promising approach for training teachers in positive behavior management strategies and for improving student disruptive behavior in the classroom.

Based on a mestizo group in Mexico, this study assesses a) the use value (UV) of the local flora, b) gendered differences in plant species, and c) the association between socio-economic variables and ethnobotanical knowledge. Methods: To assess the degree of knowledge of plant resources, we conducted 41 interviews collecting information on knowledge of local plant resources and the socio-economic situation of the informant. We also collected free listings of useful plants by category of use to identify the UV of each species. With the support of key informants, we photographed and collected the plant material recorded during the interviews and free listings on five different habitats. Paired t-tests and a Wilcoxon signed rank test were used to determine differences in the number of species known by men and women. Differences in distribution were analyzed by means of the Shapiro-Wilk's W normality tests. To determine the association of socio-economic factors and ethnobotanical knowledge, we used a non-metric multidimensional scaling analysis (NMDS). Results: Informants listed 185 species. Medicinal plants constituted the most diverse group (90 species). Tropical deciduous forest is the habitat that concentrates the highest proportion of plant resources (80 species). The use-values were classified into three groups: A (4-6 UV; three species), B (0.35-1.37 UV; 39 species) and C (0-0.29 UV; 143 species). High-quality wood species and those associated to religious ceremonies had the highest UV. Women's and men's knowledge of plant species showed statistically significant differences at the interspecific and the intracategorical levels (Student's test, T15 = 4.8, p < 0.001). Occupation, gender and age were statistically significant associated to ethnobotanical knowledge (p < 0.05), whereas income, education level, and place of origin were not.

The cultivation of medicinal plants in Naxi communities and associated the ethnomedical knowledge base for maintaining and utilizing these resources is at risk with expanded commercialization of natural resources, development policies and rapid socioeconomic change in China. Research is needed to understand the medicinal plant species maintained in Naxi homegardens, their associated use and contribution to community wellbeing, and how these practices and knowledge base varies between Naxi healers and farmers in order to develop plans for biodiversity conservation and preservation of ethnomedical practices. The main objective of this study is to document and compare medicinal plant species in Naxi homegardens and associated ethnomedical knowledge between Naxi healers and farmers.
