This study investigated use of choral reading with filtered components of speech and whispered speech on the frequency of stuttering. Three passages read by a normal adult male were lowpass filtered with kneepoint frequencies at 100 Hz (approximate glottal source), 500 Hz (source and first formant), and 1 kHz (source and the first two formants). Along with a whispered passage, a normal passage, and a control condition, these stimuli were used in a repeated-measures design with 12 adult stutterers as they read passages while listening to one of the stimuli. Frequencies of stuttering in each condition were analyzed. The choral speech, the 500-Hz, the 1-kHz, and the whispered speech conditions all decreased the frequency of stuttering while the 100-Hz stimuli did not. It is suggested that articulatory events, chiefly the encoded speech output from the vocal tract, create effective cues and may induce fluent speech in people who stutter.

Choral Reading

It is well known that stutterers experience significant decrements in their stuttering when they read or speak in unison with another person. Recently, Wingate suggested that the act of choral reading or speaking prompts the individual who is following the model speaker to emphasize vocalization and its continuity throughout the utterance. This modified vocalization may then be viewed as the immediate cause of the stutterers' reduced disfluency. To evaluate this hypothesis, ten stutterers and ten normal speakers were tested in a control and choral reading condition, In the former, subjects read in their habitual manner. In the latter, subjects read in unison with a recording of a normal adult male. Subjects' oral readings were audio-taped and then submitted to spectrographic analysis. Measures of vowel duration, peak vocal SPL and continuity of phonation were made and then treated statistically. The major findings of this study indicated that across the two conditions, both groups failed to modify their vocal SPL and continuity of phonation, They did, however, alter their vowel durations. The normal speakers increased theirs by a statistically insignificant amount, while the stutterers significantly shortened theirs. The results that pertained to vocal SPL and vowel durations seemed a function of each group's scores for these measures in the control condition as compared to the values for the same measures that were generated by the model speaker with whom subjects read in unison in the experimental condition. These and other findings and interpretations are discussed further relative to Wingate's "modified vocalization" hypothesis.

Abstract. Low precision of the inferences of data analyzed with univariate or multivariate models of the Analysis of Variance (ANOVA) in repeated-measures design is associated to the absence of normality distribution of data, nonspherical covariance structures and free variation of the variance and covariance, the lack of knowledge of the error structure underlying the data, and the wrong choice of covariance structure from different selectors. In this study, levels of statistical power presented the Modified Brown Forsythe (MBF) and two procedures with the Mixed-Model Approaches (the Akaike’s Criterion, the Correctly Identified Model [CIM]) are compared. The data were analyzed using Monte Carlo simulation method with the statistical package SAS 9.2, a split-plot design, and considering six manipulated variables. The results show that the procedures exhibit high statistical power levels for within and interactional effects, and moderate and low levels for the between-groups effects under the different conditions analyzed. For the latter, only the Modified Brown Forsythe shows high level of power mainly for groups with 30 cases and Unstructured (UN) and Autoregressive Heterogeneity (ARH) matrices. For this reason, we recommend using this procedure since it exhibits higher levels of power for all effects and does not require a matrix type that underlies the structure of the data. Future research needs to be done in order to compare the power with corrected selectors using single-level and multilevel designs for fixed and random effects.

ABSTRACT A hapten-radioimmunoassay for plasma oestradiol is described and information about the reliability of the method is given in detail. Oestradiol-3-hemisuccinate coupled to keyhole limpet haemocyanin is used for immunization of rabbits. The antiserum utilized for the assay is characterized by its titer, affinity and specificity. Following ether extraction and NaOH-light petroleum partition oestradiol is separated from crossreacting oestrogens by TLC. Oxidation of oestradiol on the plate is prevented by mercaptoethanol. To separate free and antibody bound ligand 250 μg dextran-coated charcoal per tube is used in the presence of bovine serum gammaglobulin (1 mg/ml). The between-assay precision based on 15 different determinations of control samples from normal adult male plasma was 9.4% (C. V.). The mean reagent blank value of 31 determinations was equivalent to 0.3 pg oestradiol and the detection limit in terms of the 99% confidence limit for a single blank value, was equivalent to 4.3 pg oestradiol. A procedure for detecting plasma blanks is described. Plasma oestradiol is separated from approximately all concomitant substances originally present in the sample by enzymatic conversion into oestrone and a second TLC. No plasma blanks could be detected with respect to normal adult male plasma. Normal values for adult males based on 51 subjects were characterized by a median of 17.2 pg/ml and the 95 percentiles of 9.5–27.6.

BACKGROUND Hypertension is a serious health issue and a major cardiovascular disease and stroke risk factor. In hypertensive patients, various health educational models have been used to improve their lifestyle, but the findings are inconsistent. OBJECTIVE The study assessed the effects of a lifestyle intervention program using modified Beliefs, Attitude, Subjective Standards, Enabling Factors (BASNEF) model among non-adherent hypertensive respondents in relation to the introduction of a lifestyle intervention program in the management of hypertension. METHODS This is a quantitative quasi-experimental research particularly utilizing a repeated-measures design of within-subjects approach on the 50 non-adherent patients diagnosed with essential hypertension at Moalboal, Cebu, Philippines in 2019. The respondents received five sessions of trainings based on modified BASNEF model. The Morisky Medication Adherence instrument was used. The first phase included a demographic questionnaire and the last phase comprised the evaluation of the program. Frequencies, percentages, means and standard deviations for descriptive statistics while t-test, repeated measures, ANOVA, and Pearson product moment correlation for inferential statistics. RESULTS The result indicated that the phase 1 mean (146.5) of the systolic readings differ significantly from the phase 4 mean (134.92) of the systolic readings. However, since these two means came from phases that were not consecutive, the result, as a whole, did not show a significant decrease or change when analyzed chronologically from one phase to the next. CONCLUSIONS The study has established that BASNEF model approach can be an effective BP management technique.

Purpose: This study aimed to test the effectiveness of High-Need Community-Dwelling Older Adults Care Delivery Model (HCOACDM) in Taiwan. Methods: A cluster randomized controlled trial with repeated measures design was conducted in eight community care centers, involving 145 high-need older adults who were assigned to the intervention group or comparison group. The HCOACDM was provided over 6 months. Functional ability, quality of life, depressive symptoms, and health care and social service utilizations were measured at baseline, at 3 months, and 6 months into the intervention. The participants’ satisfaction was measured at the end of 6-month intervention. Results: Positive effects were shown on all variables in the intervention group at both the 3-month and 6-month intervals (all p < .05). The intervention group had a higher satisfaction with care delivery than the comparison group ( p < .05). Discussion: The promising findings supported a long-term implementation of the HCOACDM as applicable and beneficial.

The purpose of this study was to analyze the acute effects of a standardized water training session on the shoulder rotators strength and balance in age group swimmers, in order to understand whether a muscle-strengthening workout immediately after the water training is appropriate. A repeated measures design was implemented with two measurements performed before and after a standardized swim session. 127 participants were assembled in male (n = 72; age: 16.28 ± 1.55 years, height: 174.15 ± 7.89 cm, weight: 63.97 ± 6.51 kg) and female (n = 55; age: 15.29 ± 1.28 years, height: 163.03 ± 7.19 cm, weight: 52.72 ± 5.48 kg) cohorts. The isometric torque of the shoulder internal (IR) and external (ER) rotators, as well as the ER/IR ratios, were assessed using a hand-held dynamometer. Paired sample t-tests and effect sizes (Cohen’s d) were used (p ≤ 0.05). No significant differences were found on the shoulder rotators strength or balance in males after training. Females exhibited unchanged strength values after practice, but there was a considerable decrease in the shoulder rotators balance of the non-dominant limb (p < 0.01 d = 0.366). This indicates that a single practice seems not to affect the shoulders strength and balance of adolescent swimmers, but this can be a gender specific phenomenon. While muscle-strengthening workout after the water session may be appropriate for males, it can be questionable regarding females. Swimming coaches should regularly assess shoulder strength levels in order to individually identify swimmers who may or may not be able to practice muscle strengthening after the water training.

BackgroundHigh-Fidelity Simulation (HFS) has great potential to improve decision-making in clinical practice. Previous studies have found HFS promotes self-confidence, but its effectiveness in clinical practice has not been established. The aim of this research is to establish if HFS facilitates learning that informs decision-making skills in clinical practice using MultipleCriteria DecisionMaking Theory (MCDMT).MethodsThe sample was 2nd year undergraduate pre-registration adult nursing students.MCDMT was used to measure the students’ experience of HFS and how it developed their clinical decision-making skills. MCDMT requires characteristic measurements which for the learning experience were based on five factors that underpin successful learning, and for clinical decision-making, an analytical framework was used. The study used a repeated-measures design to take two measurements: the first one after the first simulation experience and the second one after clinical placement. Baseline measurements were obtained from academics. Data were analysed using the MCDMT tool.ResultsAfter their initial exposure to simulation learning, students reported that HFS provides a high-quality learning experience (87%) and supports all aspects of clinical decision-making (85%). Following clinical practice, the level of support for clinical decision-making remained at 85%, suggesting that students believe HFS promotes transferability of knowledge to the practice setting.ConclusionOverall, students report a high level of support for learning and developing clinical decision-making skills from HFS. However, there are no comparative data available from classroom teaching of similar content so it cannot be established if these results are due to HFS alone.

AbstractPain perception is a subjective experience and highly variable across time. Brain responses evoked by nociceptive stimuli are highly associated with pain perception and also showed considerable variability. To date, the test–retest reliability of laser-evoked pain perception and its associated brain responses across sessions remain unclear. Here, an experiment with a within-subject repeated-measures design was performed in 22 healthy volunteers. Radiant-heat laser stimuli were delivered on subjects’ left-hand dorsum in two sessions separated by 1–5 days. We observed that laser-evoked pain perception was significantly declined across sessions, coupled with decreased brain responses in the bilateral primary somatosensory cortex (S1), right primary motor cortex, supplementary motor area, and middle cingulate cortex. Intraclass correlation coefficients between the two sessions showed “fair” to “moderate” test–retest reliability for pain perception and brain responses. Additionally, we observed lower resting-state brain activity in the right S1 and lower resting-state functional connectivity between right S1 and dorsolateral prefrontal cortex in the second session than the first session. Altogether, being possibly influenced by changes of baseline mental state, laser-evoked pain perception and brain responses showed considerable across-session variability. This phenomenon should be considered when designing experiments for laboratory studies and evaluating pain abnormalities in clinical practice.

Abstract Background Adequate immunization coverage in rural communities remain a challenge in Nigeria. Traditional birth attendants (TBAs) form an integral part of the social, cultural and religious fabric in most rural communities in Nigeria. Despite their limitations in handling the complications of childbirth, TBAs are widely accepted and patronized, especially in rural areas. The objectives of the project were to empower TBAs and assess the use of a culturally adapted audio-visual workshop intervention to change their knowledge, attitude and willingness to promote immunization uptake. Methods A repeated-measures design that used a convenience sampling technique to select 90 TBAs from the three geopolitical zones of Imo State, Nigeria. The TBAs were engaged through a culturally adapted audio-visual workshop. Data were collected before and immediately after intervention using a pretested questionnaire. Chi square test was done to determine any significant association with the zone of practice and paired sample t-test analysis to determine any significant pre and post intervention change. Level of significance was set at p ≤ ·05. Results More than half of the TBAs had at most, a secondary level of education (54·4%). The average length of time they practiced as TBAs was 16 years with an average of ten birth deliveries per month. After the intervention, all the respondents (100%) reported a willingness to always promote immunization uptake and also, there was a statistically significant increase in Knowledge (p < ·000). Similarly, the level of knowledge in the post intervention period appeared to be significantly associated with the zone of practice (p = ·027). Conclusion The workshop intervention empowered the TBAs irrespective of their zones of residence by successfully improving their knowledge, though at varying levels; and consequently, their willingness to always promote immunization uptake.

This is the first study to report the whole match, ball-in-play (BiP), ball-out-of-play (BoP), and Max BiP (worst case scenario phases of play) demands of professional soccer players competing in the English Championship. Effective playing time per soccer game is typically <60 min. When the ball is out of play, players spend time repositioning themselves, which is likely less physically demanding. Consequently, reporting whole match demands may under-report the physical requirements of soccer players. Twenty professional soccer players, categorized by position (defenders, midfielders, and forwards), participated in this study. A repeated measures design was used to collect Global Positioning System (GPS) data over eight professional soccer matches in the English Championship. Data were divided into whole match and BiP data, and BiP data were further sub-divided into different time points (30–60 s, 60–90 s, and >90 s), providing peak match demands. Whole match demands recorded were compared to BiP and Max BiP, with BiP data excluding all match stoppages, providing a more precise analysis of match demands. Whole match metrics were significantly lower than BiP metrics (p < 0.05), and Max BiP for 30–60 s was significantly higher than periods between 60–90 s and >90 s. No significant differences were found between positions. BiP analysis allows for a more accurate representation of the game and physical demands imposed on professional soccer players. Through having a clearer understanding of maximum game demands in professional soccer, practitioners can design more specific training methods to better prepare players for worst case scenario passages of play.
