AbstractThis study investigates whether hyperaccessibility occurs for supraliminally or subliminally presented sweets-related stimuli after prior suppression of thoughts about sweets. Thirty-three students (all female; 18—25 years old) participated in the experiment. In the first phase, half of the experimental group was instructed to suppress all sweets-related thoughts. The other participants were given control instructions. In the second phase, as part of a modified Stroop task, participants were asked to state the colour of a stimulus as quickly as possible. This stimulus could be presented either subliminally or supraliminally. In both conditions, neutral control words as well as sweets words were used. It was found that the participants in the suppression group, compared to those in the control group, showed attentional bias for the sweet-related suppressed thoughts, but that this effect was determined by the reaction times of subliminally presented sweets words. No differences were found for the control words. In addition, the study explored whether there was a relationship between thought suppression and dietary restraint attitudes. The link to dietary behaviour, however, remains unclear.

Neurofeedback (NFB) is an operant conditioning procedure, by which the subject learns to control his/her EEG activity. On one hand, Learning Disabled (LD) children have higher values of theta EEG absolute and relative power than normal children, and on the other hand, it has been shown that minimum alpha absolute power is necessary for adequate performance. Ten LD children were selected with higher than normal ratios of theta to alpha absolute power (theta/alpha). The Test Of Variables of Attention (TOVA) was applied. Children were divided into two groups in order to maintain similar IQ values, TOVA values, socioeconomical status, and gender for each group. In the experimental group, NFB was applied in the region with highest ratio, triggering a sound each time the ratio fell below a threshold value. Noncontingent reinforcement was given to the other group. Twenty half-hour sessions were applied, at a rate of 2 per week. At the end of the 20 sessions, TOVA, WISC and EEG were obtained. There was significant improvement in WISC performance in the experimental group that was not observed in the control group. EEG absolute power decreased in delta, theta, alpha and beta bands in the experimental group. Control children only showed a decrease in relative power in the delta band. All changes observed in the experimental group and not observed in the control group indicate better cognitive performance and the presence of greater EEG maturation in the experimental group, which suggests that changes were due not only to development but also to NFB treatment.

This research examines the effect of educational games on self-concept levels of inclusive students enrolled in secondary schools. The research was conducted in two secondary schools in Golbasi district of Ankara, the capital of Turkey, in the spring semester of 2015 - 2016 academic year. The research employed semi-experimental design with pretest and posttest control group. Of a total of 24 students, 12 (4 girls, 8 boys) were included in the experimental group and the other 12 (6 girls, 6 boys) were included in the control group. Educational games program, an independent variable of the research, was applied for 11 weeks, 2 lessons per week. The program that did not include educational games was applied to the control group. Self-concept Scale (SCS) was used to collect data in the research. Independent group t test was used for data analysis, and for single-factor repeated measures, two-factor ANOVA test was used. The significance level was determined to be 0.05. At the end of this research, a significant difference was found in favor of the students in the experimental group in terms of physical competence, physical appearance, peer relationships and general self-concept dimensions of the self-concept scale. On the other hand, there was not any significant difference in favor of both groups in terms of the dimension of relations with parents of the scale.

Prolonged sitting has a detrimental effect on lipid metabolism and insulin sensitivity leading to increased risks of metabolic conditions. Attendees at conferences typically sit for long periods during oral presentations. The use of visual cues or ‘just-in-time’ prompts during oral presentations can inform audiences about the deleterious effects of prolonged sitting and encourage them to avoid sitting for long periods. It remains largely unclear whether these ‘just-prompts used in a conference setting are effective in reducing prolonged sitting. The ‘just-in-time’ prompts were used in two separate conference audiences- one focused on health and the other on language. Ten sessions were randomly assigned to the experimental group (EXPT, with the JIT prompt) and ten sessions to the control group (CON, without the JIT prompt). In both conferences, the proportion of the attendees who chose not to sit during the oral presentations in the EXPT conditions was less than 10%. The main finding was that the use of the JIT prompt to discourage sitting at the health conference where attendees were likely to be knowledgeable about the dangers of prolonged sitting was ineffective (EXPT vs CON conditions, p>0.05; ES=0.69) compared to conference attendees at a language conference (EXPT vs CON conditions, p<0.05, ES=1.14).

ABSTRACT: Given the numerous reports of anthelminthic resistance of sheep nematodes to different anthelmintic compounds, this study aimed to evaluate the resistance status of gastrointestinal nematodes from naturally infected sheep to monepantel in the state of Rio Grande do Sul. Four farms that present extensive raising system and absence of anthelmintic treatment for 60 days were selected for the study. Lambs that present counts of eggs per gram of feces (EPG) ≥200 (sensitivity of 50 EPG) one day (D-1) before the treatment were select for the study and randomly separated into two groups, a control group and an experimental group treated with monepantel. Feces were collected 9 days after the treatment (D+9) for EPG counts and fecal culture. The monepantel was 100% effective only on 2. The efficacy found on farm 1, 3, and 4 were 2.82%, 25.8%, and 78.4%, respectably. There were no viable larvae post-treatment at farm 2, but the genera Haemonchus, Trichostrongylus, Cooperia, and Strongyloides were resistant to it at the other farms. This study shows the presence of parasites resistant to the treatment with monepantel, pointing to the importance of monitoring its efficacy in sheep flocks of Rio Grande do Sul, Brazil.

Abstract Objective: To compare the effect of clockwise and counterclockwise torque on the primary stability of a mini-implant with a lever-arm–shaped upper structure. Materials and Methods: Twenty-four white rabbits were used for this study. Two screw-type mini-implants were placed in each tibia. In all, 96 screws were inserted. Two weeks later, a 2-N force was applied to the mini-implants without an upper structure in eight rabbits (control group). The mini-implants of the other 16 rabbits were loaded with an upper structure (experimental group). In the experimental group, the two left mini-implants were loaded in a clockwise direction (CW group) and the two right implants were loaded in a counterclockwise direction (CCW group). The rabbits were sacrificed at 1 week or 8 weeks after loading in both control and experimental groups. The removal torque value (RTV) was measured in 15 of 16 mini-implants in each group and the remaining implant was processed for histologic examination. Results: At 1 week there were no significant differences in the mean RTV between the control, CW, and CCW groups. At 8 weeks, the RTV was higher in the control and experimental groups than in the respective 1-week groups. At 8 weeks, there were no significant differences in the RTV between the control and CW groups, but the CCW group showed a lower RTV. Conclusions: CCW torque can decrease the stability of a mini-implant, whereas a CW torque has no effect.
