The present study examined the effects of using automatic speech recognition (ASR) technology on oral complexity in a flipped English as a Foreign Language (EFL) course. A total of 160 undergraduates were enrolled in a 14-week quasi-experiment. The experimental group (EG) and the control group (CG) were taught with a flipped approach, but the EG students needed to undertake an additional pre-class task with ASR technology. In each unit, all students’ in-class task performance was recorded, based on which the metrics of oral complexity were coded and computed. A two-way between- and within-subjects repeated measures design was conducted to examine the effects of the group factor, the time factor and the group × time interaction effects. The results showed that the EG students performed statistically better than their counterparts in the CG on lexical complexity and syntactic complexity. Moreover, significant improvement in phrasal complexity was witnessed over time in both groups. Significant group × time interaction effects were witnessed on overall complexity or subordination complexity. The gradients of the EG trajectories of the two metrics were greater than those of the CG. However, on phrasal complexity, the interaction effect was not significant.

The purpose of this study was to examine the effects of group and individual goal setting versus a control condition on bowling performance (BP), personal goals (PG), and perceived goal difficulty (PGD) across five weeks. Novice bowlers (N = 36) were randomly assigned to one of the three goal conditions. Three separate 3 × 5 (Goal Condition × Time: Weeks of Study) repeated measures analysis of variance (ANOVA) revealed significant main effects for time on BP and PGD, and significant group by time interaction effects on BP and PG. The significant group × time interaction effects revealed that participants in the group goal setting condition increased both BP and PG relatively more than participants in the other goal setting conditions. Therefore, group goal setting may enhance performance in an individual sport by potentially increasing personal goal setting under difficult performance demands.

Abstract. The experiment examined the effects 4 weeks of vitamin D (Vit D) supplementation versus placebo on musculoskeletal and psychomotor performance. Thirty-two college age males (Age: 22 ± 4 y, Height: 177.7 ± 8.3 cm, Weight: 81.5 ± 14.6 kg, BF%: 19.6 ± 7.9, Vit D: 20.0 ± 7.2 ng/ml). Participants were assigned to group (Vit D vs placebo) and remained blind throughout the study. The treatments were 4000 IU of Vit D3 or placebo (dextrose) administered daily for 4 weeks. The participants underwent baseline testing for isometric strength, explosive ability and psychomotor performance, which was repeated at week 2 and week 4. Isometric tests consisted of an Isometric Mid Thigh Pull on a Force Plate (IMTP) and an upper body isometric test (UBIST) using a load cell. Peak force during a countermovement jump (CMJ) was also determined via force plate. A psychomotor vigilance test (PVT) was used to measure sustained reaction time. Analysis of the UBIST data did not reveal a significant group × time interaction (p = 0.14; Vit D pre: 553.7 ± 168.3 N, post: 585.5 ± 150.2 N; Placebo pre: 677.7 ± 182.3 N, post: 649.8 ± 236.9 N). For IMTP no significant group × time interaction (p = 0.83; Vit D pre: 2596.4 ± 342.3 N, post: 2606.9 ± 378.3 N; Placebo pre: 2684.0 ± 432.9 N, post: 2762.6 ± 440.4 N) was found. CMJ analysis did not reveal interaction effects for group × time (p = 0.21; Vit D pre: 4429.7 ± 1619.0 N, post: 4938.5 ± 2374.8 N; Placebo pre: 5537.3 ± 3027.0 N, post: 6266.9 ± 4577.3 N). For PVT (mean reaction time) there was no significant interaction effects for group × time (p = 0.35; Vit D pre: 0.304 ± 0.041 sec, post: 0.301 ± 0.053 sec; Placebo pre: 0.295 ± 0.044 sec, post: 0.284 ± 0.029 sec). In conclusion, four weeks of Vit D supplementation was not effective in increasing musculoskeletal or psychomotor performance.

The main aim of the present study was to compare the effects of flywheel strength training and traditional strength training on fitness attributes. Thirty-six well trained junior basketball players (n = 36; 17.58 ± 0.50 years) were recruited and randomly allocated into: Flywheel group (FST; n = 12), traditional strength training group (TST; n = 12) and control group (CON; n = 12). All groups attended 5 basketball practices and one official match a week during the study period. Experimental groups additionally participated in the eight-week, 1–2 d/w equivolume intervention conducted using a flywheel device (inertia = 0.075 kg·m−2) for FST or free weights (80%1 RM) for TST. Pre-to post changes in lower limb isometric strength (ISOMET), 5 and 20 m sprint time (SPR5m and SPR20m), countermovement jump height (CMJ) and change of direction ability (t-test) were assessed with analyses of variance (3 × 2 ANOVA). Significant group-by-time interaction was found for ISOMET (F = 6.40; p = 0.000), CMJ (F = 7.45; p = 0.001), SPR5m (F = 7.45; p = 0.010) and T test (F = 10.46; p = 0.000). The results showed a significantly higher improvement in CMJ (p = 0.006; 11.7% vs. 6.8%), SPR5m (p = 0.001; 10.3% vs. 5.9%) and t-test (p = 0.045; 2.4% vs. 1.5%) for FST compared to the TST group. Simultaneously, th FST group had higher improvement in ISOMET (p = 0.014; 18.7% vs. 2.9%), CMJ (p = 0.000; 11.7% vs. 0.3%), SPR5m (p = 0.000; 10.3% vs. 3.4%) and t-test (p = 0.000; 2.4% vs. 0.6%) compared to the CON group. Players from the TST group showed better results in CMJ (p = 0.006; 6.8% vs. 0.3%) and t-test (p = 0.018; 1.5% vs. 0.6%) compared to players from the CON group. No significant group-by-time interaction was found for sprint 20 m (F = 2.52; p = 0.088). Eight weeks of flywheel training (1–2 sessions per week) performed at maximum concentric intensity induces superior improvements in CMJ, 5 m sprint time and change of direction ability than equivolumed traditional weight training in well trained junior basketball players. Accordingly, coaches and trainers could be advised to use flywheel training for developing power related performance attributes in young basketball players.

Abstract: The purpose of this study was to evaluate the short-term effects of massage therapy using gas discharge visualization (GDV), a computerized biophysical electrophoton capture (EPC), in tandem with traditional self-report measures to evaluate the use of GDV measurement to assess the bioenergetic whole-person effects of massage therapy.: This study used a single treatment group, pre–post-repeated measures design with a sample of 23 healthy adults. This study utilized a single 50-min full-body relaxation massage with participants. GDV measurement method, an EPC, and traditional paper-based measures evaluating pain, stress, muscle tension, and well-being were used to assess intervention outcomes.: Significant differences were found between pre- and post-measures of well-being, pain, stress, muscle tension, and GDV parameters. Pearson correlations indicate the GDV measure is correlated with pain and stress, variables that impact the whole person.: This study demonstrates that GDV parameters may be used to indicate significant bioenergetic change from pre- to post-massage. Findings warrant further investigation with a larger diverse sample size and control group to further explore GDV as a measure of whole-person bioenergetic effects associated with massage.

Background: Previous research has suggested that electrically coupled frequency modulation (FM) systems substantially improved speech-recognition performance in noise in individuals with cochlear implants (CIs). However, there is limited evidence to support the use of electromagnetically coupled (neck loop) FM receivers with contemporary CI sound processors containing telecoils. Purpose: The primary goal of this study was to compare speech-recognition performance in noise and subjective ratings of adolescents and adults using one of three contemporary CI sound processors coupled to electromagnetically and electrically coupled FM receivers from Oticon. Research Design: A repeated-measures design was used to compare speech-recognition performance in noise and subjective ratings without and with the FM systems across three test sessions (Experiment 1) and to compare performance at different FM-gain settings (Experiment 2). Descriptive statistics were used in Experiment 3 to describe output differences measured through a CI sound processor. Study Sample: Experiment 1 included nine adolescents or adults with unilateral or bilateral Advanced Bionics Harmony (n = 3), Cochlear Nucleus 5 (n = 3), and MED-EL OPUS 2 (n = 3) CI sound processors. In Experiment 2, seven of the original nine participants were tested. In Experiment 3, electroacoustic output was measured from a Nucleus 5 sound processor when coupled to the electromagnetically coupled Oticon Arc neck loop and electrically coupled Oticon R2. Data Collection and Analysis: In Experiment 1, participants completed a field trial with each FM receiver and three test sessions that included speech-recognition performance in noise and a subjective rating scale. In Experiment 2, participants were tested in three receiver-gain conditions. Results in both experiments were analyzed using repeated-measures analysis of variance. Experiment 3 involved electroacoustic-test measures to determine the monitor-earphone output of the CI alone and CI coupled to the two FM receivers. Results: The results in Experiment 1 suggested that both FM receivers provided significantly better speech-recognition performance in noise than the CI alone; however, the electromagnetically coupled receiver provided significantly better speech-recognition performance in noise and better ratings in some situations than the electrically coupled receiver when set to the same gain. In Experiment 2, the primary analysis suggested significantly better speech-recognition performance in noise for the neck-loop versus electrically coupled receiver, but a second analysis, using the best performance across gain settings for each device, revealed no significant differences between the two FM receivers. Experiment 3 revealed monitor-earphone output differences in the Nucleus 5 sound processor for the two FM receivers when set to the +8 setting used in Experiment 1 but equal output when the electrically coupled device was set to a +16 gain setting and the electromagnetically coupled device was set to the +8 gain setting. Conclusions: Individuals with contemporary sound processors may show more favorable speech-recognition performance in noise electromagnetically coupled FM systems (i.e., Oticon Arc), which is most likely related to the input processing and signal processing pathway within the CI sound processor for direct input versus telecoil input. Further research is warranted to replicate these findings with a larger sample size and to develop and validate a more objective approach to fitting FM systems to CI sound processors.

Background Disease management and chronic care models have evidenced success with heart failure (HF) patients but have not fully explored patients' engagement/activation in self- care. Objective Determine efficacy of a patient activation intervention (Heart PACT Program) compared to usual care on activation and self-care management in HF. Methods This study was a 4-year, randomized, 2-group, repeated-measures design (baseline, 3 months, and 6 months). Following consent, 84 patients were stratified by activation level and randomly assigned to usual care (n = 41), or usual care plus the activation intervention (n = 43). The primary outcome variables were patient activation using the Patient Activation Measure (PAM) (Hibbard et al., 2005), and self-care using the Self-Care for Heart Failure Index (SCHFI) (Riegel et al., 2004) and the Medical Outcomes Study (MOS) Specific Adherence Scale. The intervention consisted of individual meetings and phone call follow-up over 6 months based on the patient's level of activation: stage 1 or 2 (low activation), stage 3 (medium), or stage 4 (high) as assessed by the patient's self-report PAM score and brief interview. The leaders collaborated with patients to improve activation and self-management of HF: adhering to medications; monitoring weight, blood pressure, and symptoms; and implementing health behavior goals. Findings Participants were primarily male (99%), Caucasian (77%), and classified as NYHA III (52%). The mean age was 66 years (SD 11). The majority (71%) of participants reported 3 or more comorbid conditions. The intervention group compared to the usual care group showed a significant increase in activation/PAM scores from baseline to 6 months (significant group by time interaction linear contrast, F=16.90, p=.02). Although the baseline MOS mean was lower in the intervention group, results revealed a significant group by time effect (F=9.16, p = .001) with the intervention group improving more over time. There were no significant group by time interactions for the SCHFI. Conclusion Patient activation can be improved through targeted intervention. The patient activation model has the potential to change approaches to tailored patient education for self-management in heart failure.

The Positive Youth Development (PYD) approach identifies adolescents as resources to be empowered rather than problems to be solved. All adolescents have strengths and will fully develop when these strengths are integrated with healthy resources in the diverse environments where they live and interact. The objective of this study was twofold: (1) to present the Positive Development Program for Adolescents living in rural areas (DPAR Program) and (2) to pilot test the intervention program. The DPAR program was evaluated using a repeated-measures design before and after the intervention, with an intervention group and a control group. The sample consisted of 176 adolescents between 11 and 15 years old (M = 12.89, SD = 0.90) who belonged to two high schools with similar characteristics located in rural settings. A mixed-design analysis of variance was performed for each dependent variable. Results showed a significant increase in most of the study variables (self-esteem, self-efficacy, group identity, empathy, relational skills, assertiveness, and conflict resolution) and a significant decrease in alexithymia, as well as better academic performance. All this evidence indicates that the DPAR program is effective in promoting positive adolescent development and addresses the lack of programs based on the PYD approach in rural areas.

This study assessed the effectiveness of a strengths-based randomized controlled trial focused on fostering all 24 character strengths in a group of 75 participants from a University in Tunisia. Participants randomly assigned to the challenge condition (n = 40) received an email each day for 24 days, that highlighted a particular strength of the day including why the strength is valuable, how to implement the strength behaviourally, and a motto related to that strength. Those in the control condition (n = 35) simply received emails containing the motto for each strength daily for 24 days. We assessed all participants’ levels of happiness before the experiment (T0), the day following the experiment (T1), and one-month following the experiment (T2). Results from a 2 (group) X 3 (time) split plot ANOVA revealed a significant group-by-time interaction, such that at T2 the experimental group had greater happiness scores than the control group. These findings provide some evidence that even “minimalist” interventions (involving the receipt of emails encouraging character-strength development), might be effective for promoting gains in happiness even one month after the intervention.
