We investigated whether camera placement affects peer teachers’ focus of attention during reflection. Preservice music teachers ( N = 14) reflected on peer teaching videos that had been recorded simultaneously from a head-mounted camera and a tripod-mounted camera at the back of the classroom. Participants completed the teaching reflection cycle twice, providing their observation comments in response to open-ended prompts. Responses were coded, with a single sentence as the unit of analysis, and a three-way repeated measures analysis of variance (ANOVA) revealed a significant difference in comment frequencies according to comment type (student-focused or teacher-focused) but not according to camera placement or trial. Our results corroborate previous research indicating that undergraduate peer teachers focus more on themselves than on their peers, and suggest that placing the camera in a position that shows the students, rather than the teacher, does not seem to affect this tendency. We discuss the implications for peer teaching experiences in teacher education courses.

Mindfulness meditation has frequently used sound and music as an important component. However, research on effective music stimuli is scarce. After a series of studies evaluating the most effective, useful, and preferred auditory stimuli, we were interested in exploring whether these effective musical features were transferred to new music. In this study, we evaluate our original music stimuli with three new stimuli composed under similar principles. Non-musician and musician participants ( N = 114) in a multisite study evaluated their mindfulness state after listening to four music stimuli, and rated their usefulness and preference. Results from a repeated-measures analysis of variance (ANOVA) at each site indicated no significant difference in mindfulness effectiveness. Friedman’s ANOVAs for the usefulness of the music stimuli showed similar non-significant results in both sites. A mixed model among sites did not show significant differences among groups. Preference rankings were not significantly different for non-musicians, but musicians did show a statistically significant preference of the Original stimuli over Stimulus 2, probably due to sound quality. These results indicate the feasibility of transferring previously researched and effective musical features to new stimuli. Identifying the effective “active ingredients” of music interventions may be one way of supporting evidence-based practice in music therapy.

This study was carried out using 80 multiparous Awassi ewes during breeding season to compare the effects of controlled internal drug release (CIDR) withdrawal time on ewe fertility. Ewes were equally and randomly allotted into 4 groups (n = 20/group). Ewes had a CIDR inserted for 3, 6, 9, or 12 days with intramuscular administration of 300 IU of equine chorionic gonadotropin (eCG) at withdrawal time. Oestrus was detected using vasectomized ram starting 12 h after CIDR withdrawal and repeated every 12 h up to 84 h. Blood samples were collected from all groups at the time of CIDR withdrawal for measuring of oestradiol (E2) and progesterone (P4) serum concentrations using commercial ELISA kits and micro-titrimetric plates. Timed insemination was performed 48 h post CIDR withdrawal in all groups. Pregnancy was diagnosed by ultrasonography at day 23 post-insemination and confirmed at day 35. Comparisons among groups were evaluated using Chi Square (χ2) test in all measured parameters except hormones levels, which analysed by repeated-measures analysis of variance (ANOVA), using SAS (SAS Institute Inc., Cary, NC, USA). A difference was considered significant at P < 0.05 level. The results revealed that the retention, vaginal discharge and drawstring breakage rates after CIDR removal were insignificantly differed between all groups. On the other hand, pregnancy rate was significantly (P ≤ 0.05) higher in 9-d and 6-d groups (68.4 and 60%, respectively) than the 3-d group. While, no significant difference was detected between 12d group and other groups. The heat detection rate was significantly (P ≤ 0.05) higher in 12d group (100%) than 6-d and 3-d groups (80 and 45%, respectively). While, no significant difference was detected between 12-d and 9-d groups in heat detection rate. P4 was significantly higher in the 12-d group (13.4 ± 3.06 ng mL−1) than other groups. While E2 was significantly lower in the 12-d group (1.6 ± 0.06 pg mL−1) than other groups. These results indicated that withdrawal of CIDR devices after 9 days are efficient in synchronizing oestrus in ewes and provided higher pregnancy rate.

Objectives: Environmental cues, such as pictures, could be helpful in improving room-finding and wayfinding abilities among older patients. The aim of this study was to identify picture categories that are preferred and easily remembered by older patients and cognitively impaired patients and which therefore might be suitable for use as environmental cues in acute care settings. Methods: Twelve pictures were presented to a sample of older patients ( n = 37). The pictures represented different categories: familiarity (familiar vs. unfamiliar), type of shot (close-up vs. wide shot), and picture content (nature vs. animal vs. urban). We tested the patients’ votes of preference and abilities to identify and immediately recall pictures. Cognitively impaired patients ( n = 14) were assessed by the abbreviated mental test and the mini mental state examination and were compared with patients without cognitive impairments ( n = 23) using a repeated measures analysis of variance. Results: The results showed a main effect of familiarity on positive vote and recall of pictures. The absence of interaction effects of familiarity and group indicated an overall impact of familiarity on the sample. Within cognitively impaired patients, a significant difference in recall of picture content between urban (20%) and animal (9%) was found. Conclusions: Pictures, which patients were able to relate to in terms of familiarity and the characteristics urban and nature, seem to be suitable for use as environmental cues. Besides functioning as such, we assume, based on literature, that pictures could further enhance the ambiance or serve as prompts for communication and interaction.

AbstractBiomechanical imbalances and inefficient functional movements are considered contributing factors to running-related injuries. Clinical Pilates uses a series of exercises focused on retraining normal movement patterns. This study investigated whether a 6-week course of Clinical Pilates improves functional movement and thereby, potentially, reduces the risk of running-related injuries associated with movement dysfunction. A modified functional movement screen was used to analyze the functional movement ability of forty runners. Forty participants completed a 6-week course of Clinical Pilates delivered by a Clinical Pilates instructor. The movement screen was carried out 3 times for each runner: 6 weeks pre-intervention (baseline), within one week pre-intervention (pre) and within one week post-intervention (post). Repeated-measures analysis of variance and post-hoc tests found significant increases in scores between baseline and post (mean±SD; 13.4±2.4 vs. 17.0±1.7, p<0.01) and pre and post (mean±SD; 13.5±2.5 vs. 17.0±1.7, p<0.01), but no significant difference between baseline and pre (p=0.3). A 6-week course of Clinical Pilates significantly improves functional movement in recreational runners, and this may lead to a reduction in the risk of running-related injuries.

The design of this study is a quasi-experimental. The sample used in this study was eight respondents with certain criteria. Treat physical activity twice on different days with 4 measurements of uric acid levels. The method of this study is repeated measure analysis. When subjects are measured repeatedly, requiring fewer subjects per experiment, then repeated measures analysis can be used. The results showed that the treatment of badminton had a significant effect on changes in uric acid levels with a probability value of 0,038. These results were obtained by using the Greenhouse-Geisser test where the assumptions of normality and homogeneity were satisfied. From the marginal test results using pairwise comparisons, there was a significant difference in the average uric acid levels at 15 minutes after exercise and 9 hours the following day, where there was a decrease of 1.169 mg/dl. Badminton can reduce uric acid levels, which is indicated by a decrease of 0.15 mg/dl at 09.00 the next day compared to before exercise. Marginally, this decrease is not statistically significant, but regular badminton can be an option for physical activity for those who want to reduce uric acid levels.

BACKGROUND: Various interventions have been recommended to increase ankle dorsiflexion range of motion (DFROM); however, few studies have investigated the long-term effects of applying gastrocnemius stretching with talus-stabilizing taping (GSTST). OBJECTIVE: To compare the effects of gastrocnemius stretching (GS) and GSTST on DFROM and balance in subjects with limited DFROM. METHODS: Twenty-six subjects with limited DFROM were randomly allocated to either the GS group (n= 13) or GSTST group (n= 13) for 6 weeks. Maximum DFROM before heel-off during gait, passive DFROM, posterior talar glide, flexibility of the gastrocnemius, and the lower-quarter Y-balance test (YBT-LQ) were assessed pre-intervention and post-intervention. Two-way repeated-measures analysis of variance was used to compare the changes in variables. RESULTS: The GSTST group had greater maximum DFROM before heel-off, passive DFROM, and posterior talar glide than the GS group. Gastrocnemius flexibility and YBT-LQ scores increased significantly post-intervention in both groups; however, there was no significant difference between the groups. CONCLUSIONS: GSTST is recommend for improving ankle DFROM and balance in subjects with limited DFROM.

Objective: We evaluated learning retention in interns exposed to simulation. It was hypothesized that learning would degrade after 6 months and there would be a difference in retention between interns who played a critical role versus those who did not. Methods: A total of 23 groups of 5 to 9 interns underwent a cardiac scenario twice during 1 simulation experience and again 6 months later. We captured 69 recordings (23 before debrief at baseline [PrDV], 23 after debrief at baseline [PoDV], and 23 at 6-month follow-up [FUV]). Students were assigned different roles, including the critical role of “doctor” in a blinded, haphazard fashion. At 6-month follow-up, 12 interns who played the role of doctor initially were assigned that role again, while 11 interns who played noncritical roles initially were newly assigned to doctor. All videos of intern performance were scored independently and in a blinded fashion, by 3 judges using a 15-item check list. Results: Repeated-measures analysis of variance for interns completing all 3 time points indicated a significant difference between time points (F2,22 = 112, p = .00). Contrasts showed a statistically significant difference between PrDV and PoDV (p = .00), and PrDV and FUV (p = .00), but no difference between PoDV and FUV (p = .98). This was consistent with results including all data points. Checklist scores were more than double for PoDV recordings (16) and FUV (15), compared to PrDV recordings (6.6). Follow-up scores comparing old to new doctors showed no statistically significant difference (15.4 vs 15.2 respectively, t21 = 0.26, p = .80, d = .11). Conclusions: Learning retention was maintained regardless of role.

Background: Nowadays, the high prevalence of hypertension and its serious complications for affected patients have made this disease a major health issue worldwide. Hypertension, like other chronic diseases, reduces the patients’ quality of life. Maintaining and improving their lifestyles requires the serious support of families. Objectives: This study aimed to explore the effect of the family-centered empowerment model on the quality of life of patients with hypertension. Methods: This clinical trial was performed on 70 hypertensive patients who were referred to two comprehensive health centers in Zahedan University of Medical Sciences in Zahedan, southeastern Iran, in 2020. The participants were selected and randomly allocated based on the inclusion criteria to the intervention (n = 35) and control (n = 35) groups using the consort. The participants in the intervention group received training in four 60-min sessions individually based on the family empowerment model. To collect data, a personal information form and the Quality of Life Questionnaire for hypertensive patients were used. The questionnaire was completed before the intervention and one and three months after the intervention by a self-report method. The collected data were analyzed by SPSS-22 using the independent samples t test, chi-square test, and repeated-measures analysis of variance. Results: The results of repeated-measures analysis of variance regarding the effect of time and group on the quality of life showed a statistically significant difference in the second and third phases between the two groups. In other words, the two variables of intervention and time affected the mean score of quality of life, and a statistically significant difference was observed in the measured time intervals (P < 0.001). Conclusions: This study showed that implementing the family-centered empowerment model improves the quality of life of patients with hypertension. Therefore, we recommend employing this method by nurses to engage the patients with chronic diseases and their families in the process of treatment.
