Objective: Currently, there are multiple bed-making tools utilized by consumers and businesses with the intention of increasing safety and reducing time to make a bed. In this study, we will compare musculoskeletal stress, time, and preference of making a bed using the EasyTuck pad versus three other bed-making tools and making a bed without any bed-making tool. Methods: A sample of ten subjects performed the task of making a queen size mattress bed with one bottom fitted sheet and one top flat sheet, using the EasyTuck pad versus three other bed-making tools, and making a bed without any bed-making tool, in a random order. Time to make the bed, forces on the low back, shoulders and wrist, and the number of times each individual bent forward were measured during each trial. In addition, subjective preferences were measured using a simple questionnaire. Results: Repeated measures analysis of variance was used to analyze the differences between the five different procedures. There were significant differences for all the measured variables. Regarding the time needed to make one bed, the EasyTuck pad had the least time range (80.6 s±4.3), which was approximately 40 s less than making the bed with no tool (p<0.001). Furthermore, for the overall lumbar spine impulse force, the EasyTuck pad had the largest overall reduction in this category (90.6%). Regarding the subjective data, the EasyTuck pad had an overall rating of 9.4 out of 10, compared to the other tools with ratings of 5.9, 5.1, and 3.4 out of 10, which was a statistically significant difference (p<0.001). Conclusion: Making beds on a regular basis poses risk of injury, especially for those who are required to perform this for their occupation. However, using assistive tools for bed-making, could minimize, and prevent injuries and overload to the lower back, and other parts of the body, making the bed-making task safer. Based on our findings, the EasyTuck pad was by far the most efficient and safest tool to assist in making beds, with the lowest possible risk of injury when compared to all the other tools tested.

This study examined the organizational impression management (OIM) strategies adopted by the US law firms on Twitter. The Diction software package for textual analysis of nearly 10,000 tweets, coupled with statistical analysis, was used to assess the significant differences among law firms over 5 years. Although higher revenue law firms were found to exhibit higher certainty and optimism than lower revenue firms, analysis via repeated measures analysis of variance did not show significant differences. When companies’ OIM strategies were observed over a period of 5 years, there was a statistically significant difference in activity between 2011 and 2014. The findings add to the body of corporate communications research through examination of social media OIM strategies used by financially successful US law firms.

Objective: To examine various institution and student demographics and the ratings of Satisfaction (SAT) and Importance (IMP) for several programmatic variables within Athletic Training Education Programs (ATEPs). Design and Setting: A survey of SAT and IMP ratings of programmatic variables conducted with accredited, entry-level ATEPs. Subjects: Students enrolled in their final semester/term. Measurements: Students' SAT and IMP was measured by asking students to rate, on a 10-point Likert scale, seven programmatic factors. Various institution/program (state versus private affiliation, athletic division, Carnegie classification, and university enrollment) and student (age, gender, self-reported grade point average) demographic data were collected. Results: The sample consisted of 403 students from 99 institutions. Total SAT and IMP was computed by calculating the mean score across all seven factors. An analysis of variance showed a significant difference (F2,275 = 4.25, P = .01) for SAT within Carnegie classification with master's institution students more satisfied than doctoral institution students. A repeated measures analysis found significant differences (F6,292 = 34.77, P &lt; .001) between SAT factors with students more satisfied with instructor availability than the other factors A repeated measures analysis found significant differences (F6,292 = 53.64, P &lt; .001) between IMP factors with the quality of instruction in the major and quality of clinical experiences rated higher than the other factors Conclusions: Our results revealed that the type of institution has a greater effect upon student ratings of SAT and IMP than the student characteristics themselves.

In cattle, core body temperature can be used as an important indicator of heat stress level. However, accurately recording core body temperature can be difficult and labor intensive. The objectives of the current study were 1) to compare the recorded tympanic and tail body temperature measurements in steers and 2) to determine the body temperature change of Angus and Brahman steers in a hot and humid environment. Data was analyzed using a repeated measure model where repeated measures were hourly tympanic and tail temperatures and their difference for individual steers during the day of the experiment. There was a significant breed effect (P=0.01), hour (P<0.0001) and breed by hour interaction (P<0.0001) for the tympanic temperature. Brahman steers, which are known to have superior thermotolerance, maintained a lower body temperature than the Angus steers during the afternoon under grazing conditions. In the Brahman steers there was only a minimal increase in the body temperature throughout the day, an evidence of the thermotolerance ability of the breed. In the Angus steers, which experienced an increase in their body temperature from hour to hour with a peak around 1600 hour; there was a significant difference between the tympanic and tail temperature during the times when the body temperature as measured by the tympanic recordings was the highest (1300 to 1700 hour). Our results indicate that the tympanic temperature can be used to accurately and continuously monitor core body temperature in a natural environment for up to several days and without disturbing the animal.

Abstract Context Muscle damage and delayed onset muscle soreness (DOMS) can occur following intense exercise. Various modalities have been studied to improve blood lactate accumulation, which is a primary reason for DOMS. It has been well established that active recovery facilitates blood lactate removal more rapidly that passive recovery due to the pumping action of the muscle. The pedal pump is a manual lymphatic technique used in osteopathic manipulative medicine to increase lymphatic drainage throughout the body. Pedal pump has been shown to increase lymphatic flow and improve immunity. This may improve circulation and improve clearance of metabolites post-exercise. Objective This study compared the use of pedal pump lymphatic technique to passive supine recovery following maximal exercise. Methods 17 subjects (male n = 10, age 23 ± 3.01; female n = 7, age 24 ± 1.8), performed a maximal volume O2 test (VO2 max) using a Bruce protocol, followed by a recovery protocol using either pedal pump technique or supine passive rest for 10 min, followed by sitting for 10 min. Outcome measures included blood lactate concentration (BL), heart rate (HR), systolic blood pressure (SBP) and VO2. Subjects returned on another day to repeat the VO2 max test to perform the other recovery protocol. All outcomes were measured at rest, within 1- minute post-peak exercise, and at minutes 4, 7, 10 and 20 of the recovery protocols. A 2 × 6 repeated measures ANOVA was used to compare outcome measures (p ≤ 0.05). Results No significant differences were found in VO2, HR, or SBP between any of the recovery protocols. There was no significant difference in BL concentrations for recovery at minutes 4, 7, or 10 (p > 0.05). However, the pedal pump recovery displayed significantly lower BL concentrations at minute 20 of recovery (p = 0.04). Conclusion The pedal pump significantly decreased blood lactate concentrations following intense exercise at recovery minute 20. The use of manual lymphatic techniques in exercise recovery should be investigated further.

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.

Background: Although assessment of passive maximum foot dorsiflexion angle is performed routinely, there is a paucity of information regarding adolescents’ foot and foot segment motion during this procedure. There are currently no trials investigating the kinematics of the adolescent foot during passive foot dorsiflexion. Methods: A six-camera optoelectronic motion capture system was used to collect kinematic data using the Oxford Foot Model. Eight female amateur gymnasts 11 to 16 years old (mean age, 13.2 years; mean height, 1.5 m) participated in the study. A dorsiflexing force was applied to the forefoot until reaching maximum resistance with the foot placed in the neutral, pronated, and supinated positions in random order. The maximum foot dorsiflexion angle and the range of movement of the forefoot to hindfoot, tibia to forefoot, and tibia to hindfoot angles were computed. Results: Mean ± SD maximum foot dorsiflexion angles were 36.3° ± 7.2° for pronated, 36.9° ± 4.0° for neutral, and 33.0° ± 4.9° for supinated postures. One-way repeated-measures analysis of variance results were nonsignificant among the 3 groups (P = .70), as were the forefoot to tibia angle and hindfoot to tibia angle variations (P = .091 and P = .188, respectively). Forefoot to hindfoot angle increased with the application of force, indicating that in adolescents, the forefoot does not lock at any particular posture as portrayed by the traditional Rootian paradigm. Conclusions: Participants had very flexible foot dorsiflexion, unlike those in another study assessing adolescent athletes. This finding, together with nonsignificant statistical results, implies that foot dorsiflexion measurement may be performed at any foot posture without notably affecting results.

Methodological Considerations

This study had two primary purposes: (1) to investigate the effect of register, direction, and magnitude on musicians’ evaluation of chamber ensemble intonation, and (2) determine whether a novel nonparametric technique, ordinal pattern analysis (OPA), was a viable alternative to repeated-measures analysis of variance (rANOVA). I digitally mastered a recording of a string quartet performing a phrase from Capriol Suite by altering the intonation of the violin or cello voice ±20 and 30 cents sharp and flat. Participants ( N = 72) completed a discrimination task and an evaluation task with the recordings, with task order, and within-task item order presented in a random order. Analysis using rANOVA revealed significant differences due to register, direction, and magnitude: Excerpts with cello errors were rated as more in tune than excerpts with violin errors; excerpts with flat errors were rated as more in tune than excerpts with sharp errors, and excerpts with 20-cent magnitude errors were rated as more in tune than excerpts with 30-cent magnitude errors. OPA results were consistent with rANOVA results. Substantive implications for music teaching and learning are discussed alongside methodological considerations and implications for music education research using repeated-measures designs.

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.

<p><strong>INTRODUCTION: </strong>Perioperative hyperglycemia has been shown to be related to higher levels of morbidity and mortality in patients on cardiopulmonary bypass (CPB) undergoing coronary artery bypass grafting (CABG), both diabetic and non-diabetic. Blood electrolytes, like sodium, potassium, calcium, and chloride play a very important role in the normal functioning of the body and can lead to a variety of clinical disorders if they become deficient. A minimal number of studies have been conducted on the simultaneous perioperative changes in both blood glucose and electrolyte levels during CPB in Pakistan. Therefore, our aim is to record and compare the changes in blood glucose and electrolyte levels during CPB in diabetic and non-diabetic patients.</p><p><strong>MATERIALS &amp; METHODS: </strong>This was a prospective, observational study conducted on 200 patients who underwent CABG with CPB, from October 2014 to March 2015. The patients were recruited from the Cardiac Surgery Ward, Civil Hospital Karachi after they complied with the inclusion criteria. Repeated-measures analysis of variance (ANOVA) was used to compare the trend of the changes perioperatively for the two groups.</p><p><strong>RESULTS: </strong>There was no significant difference in changes in blood glucose between the two groups (<em>P</em> = 0.62). The only significant difference detected between the two groups was for PaCO<sub>2</sub> (<em>P</em> = 0.001). Besides, further analysis revealed insignificant group differences for the trend changes in other blood electrolytes (<em>P</em> &gt; 0.05).</p><p><strong>CONCLUSION: </strong>Our findings highlighted that there is no significant difference in blood electrolytes changes and the increase in blood glucose levels between diabetic and non-diabetic patients.</p>
