    To examine the effects of individual video-feedback on the generic communication skills, clinical competence (i.e. adherence to practice guidelines) and motivational interviewing skills of experienced practice nurses working in primary care. Continuing professional education may be necessary to refresh and reflect on the communication and motivational interviewing skills of experienced primary care practice nurses. A video-feedback method was designed to improve these skills. Pre-test/posttest control group design. Seventeen Dutch practice nurses and 325 patients participated between June 2010-June 2011. Nurse-patient consultations were videotaped at two moments (T0 and T1), with an interval of 3-6 months. The videotaped consultations were rated using two protocols: the Maastrichtse Anamnese en Advies Scorelijst met globale items (MAAS-global) and the Behaviour Change Counselling Index. Before the recordings, nurses were allocated to a control or video-feedback group. Nurses allocated to the video-feedback group received video-feedback between T0 and T1. Data were analysed using multilevel linear or logistic regression. Nurses who received video-feedback appeared to pay significantly more attention to patients' request for help, their physical examination and gave significantly more understandable information. With respect to motivational interviewing, nurses who received video-feedback appeared to pay more attention to 'agenda setting and permission seeking' during their consultations. Video-feedback is a potentially effective method to improve practice nurses' generic communication skills. Although a single video-feedback session does not seem sufficient to increase all motivational interviewing skills, significant improvement in some specific skills was found. Nurses' clinical competences were not altered after feedback due to already high standards. © 2014 John Wiley & Sons Ltd.

    Guideline adherence in physical therapy is far from optimal, which has consequences for the effectiveness and efficiency of physical therapy care. Programmes to enhance guideline adherence have, so far, been relatively ineffective. We systematically developed a theory-based Quality Improvement in Physical Therapy (QUIP) programme aimed at the individual performance level (practicing physiotherapists; PTs) and the practice organization level (practice quality manager; PQM). The aim of the study was to pilot test the multilevel QUIP programme's effectiveness and the fidelity, acceptability and feasibility of its implementation. A one-group, pre-test, post-test pilot study (N = 8 practices; N = 32 PTs, 8 of whom were also PQMs) done between September and December 2009. Guideline adherence was measured using clinical vignettes that addressed 12 quality indicators reflecting the guidelines' main recommendations. Determinants of adherence were measured using quantitative methods (questionnaires). Delivery of the programme and management changes were assessed using qualitative methods (observations, group interviews, and document analyses). Changes in adherence and determinants were tested in the paired samples T-tests and expressed in effect sizes (Cohen's d). Overall adherence did not change (3.1%; p = .138). Adherence to three quality indicators improved (8%, 24%, 43%; .000 ≤ p ≤ .023). Adherence to one quality indicator decreased (-15.7%; p = .004). Scores on various determinants of individual performance improved and favourable changes at practice organizational level were observed. Improvements were associated with the programme's multilevel approach, collective goal setting, and the application of self-regulation; unfavourable findings with programme deficits. The one-group pre-test post-test design limits the internal validity of the study, the self-selected sample its external validity. The QUIP programme has the potential to change physical

    Two versions (modified pre-test and modified post-test) of PIN-micro code were used to analyse the fuel rod behaviour of three FUMEX experiments. The experience of applying PIN-micro code with its simple structure and old conception of the steady-state operation shows significant difficulties in treating the complex processes like those in FUMEX experiments. These difficulties were partially overcame through different model modifications and corrections based on special engineering estimations and the results obtained as a whole do not seem unreasonable. The calculations have been performed by a group from two Bulgarian institutions in collaboration with specialists from the Kurchatov Research Center. 1 tab., 14 figs., 8 refs.

    Full Text Available The present study aimed to investigate the effectiveness of group cognitive behavioral therapy in reducing anxiety and depression and glycemic control in children with type I diabetes. The study was quasi- experimental with a pre-test, post-test design with control group. For this purpose, 30 children with diabetes were selected from Imam Reza Hospital in Mashhad. The children were randomly assigned into two experimental group (15 and control group (15. The experimental group was undergone eight 2-hour sessions of cognitive-behavioral training. Before and after the intervention, the Multidimensional Anxiety Scale for Children, which included four components of social anxiety, physical symptoms, harm avoidance, and separation anxiety, and Children Depression Inventory was administrated in both groups. The findings from the covariance analysis test revealed that depression and anxiety and glycemic control in experimental group was controlled at post-test and depression score in experimental group compared to the control group at post-test was decreased. The findings from the multivariate covariance analysis test between components of, physical symptoms, harm avoidance, separation anxiety, and social anxiety revealed meaningful differences between the two groups in social anxiety post-test score. Thus, cognitive behavior therapy can be effective for depression, anxiety, and blood sugar control in children.

    Oncology patients may respond to radiation treatment with anxiety expressed as stress, fear, depression, and frustration. This study aimed to investigate effects of music intervention on reducing pre-radiotherapy anxiety in oncology patients. Quasi-experimental study with purposeful sampling was conducted in the Department of Radiation Oncology, at Far Eastern Memorial Hospital, Taipei, Taiwan. Subjects were assigned into a music group (n = 100) receiving 15 min of music therapy prior to radiation and a control group (n = 100) receiving 15 min rest prior to radiation. Both groups were evaluated for pre- and post-test anxiety using the State-Trait Anxiety Inventory. Physiological indicators of anxiety were measured pre- and post-test. Baseline State/Trait scores and vital signs were comparable between groups (P > 0.05). Mean change in pre- and post-test State/Trait scores showed significant decreases from baseline to post-test in both groups (all P music therapy and control groups in mean change of State anxiety scores (mean decreases 7.19 and 1.04, respectively; P music and control groups (-5.69 ± 0.41 mmHg vs. -0.67 ± 1.29 mmHg, respectively; P = 0.009). Music therapy decreased State anxiety levels, Trait anxiety levels and systolic blood pressure in oncology patients who received the intervention prior to radiotherapy. Copyright © 2012 Elsevier Ltd.

    Childhood is important and critical period in human life. The foundation of ego is shaped in childhood. Play therapy is one of the successful strategies to help children with inner conflicts problems. This method of psychotherapy is base on the normal learning processes of children, provides solutions to relieve feelings of stress, and expands self-expression. Group play therapy can enhance the self-awareness, self- regulation, social communication, empathy and adoptability in children. Present study investigated the effects of play therapy on relational and emotional skills of pre-school children. For this purpose, the total numbers of 372 pre-school children were randomly selected, and divided into two equal groups (case and control). In next step, the BUSSE-SR methodology was used for evaluation and comparison of self-awareness, self-regulation, social interaction, empathy, adoptability, and control groups. Pre-test were performed for both groups and case group was involved in-group play therapy. According to the results of post-test, correlation of variables between case-control groups was examined by multivariate analysis of covariance. Frequency of boys and girls in our sample were 51.3 and 48.7 percent, respectively. The mean age of children was 5.1±0.6 year. According to the results of present study, play therapy significantly enhanced the social-emotional skills (Pplay therapy can be used in pre-school centers to help children learn problem-solving skills and communicate with others.

    As part of the PSI/HSK STARS project, pre-test calculations have been performed for a KKL turbine trip test at 109% power using the RETRAN-3D code. In this paper, we first present the results of these calculations, together with a description of the test and a comparison of the results with the measured plant data, and then discuss in more detail the differences between the pre-test results and the plant measurements, including the differences in the initial and boundary conditions, and how these differences influenced the calculated results. Finally, we comment on a series of post-test and sensitivity analyses, which were performed to resolve some of the discrepancies. The results of the pre-test (blind) calculations show good overall agreement with the experimental data, particularly for the maximum in the steam-line mass flow rate following the opening of the turbine bypass valves. This is of critical importance, since the steam-line flow has the least margin to the reactor scram limit. The agreement is especially good since the control rod banks used for the selected rod insertion were changed from those given in the test specification. Following a review of the comparison of the pre-test calculations with the measured data, several deficiencies in the RETRAN-3D model for KKL were identified and corrected as part of the post-test analysis. This allowed for both an improvement in the calculated results, and a deeper understanding of the behaviour of the turbine trip transient. (author)

    A flipped classroom approach has been implemented in an undergraduate fluid mechanics course. Students watch short on-line videos before class, participate in active in-class problem solving (in dyads), and complete individualized on-line quizzes weekly. In-class activities are designed to achieve a trifecta of: 1. developing problem solving skills, 2. learning subject content, and 3. developing inquiry skills. The instructor and assistants provide critical ``just-in-time tutoring'' during the in-class problem solving sessions. Comparisons are made with a simultaneous section offered in a traditional mode by a different instructor. Regression analysis was used to control for differences among students and to quantify the effect of the flipped fluid mechanics course. The dependent variable was the students' combined final examination and post-concept inventory scores and the independent variables were pre-concept inventory score, gender, major, course section, and (incoming) GPA. The R-square equaled 0.45 indicating that the included variables explain 45% of the variation in the dependent variable. The regression results indicated that if the student took the flipped fluid mechanics course, the dependent variable (i.e., combined final exam and post-concept inventory scores) was raised by 7.25 points. Interestingly, the comparison group reported significantly more often that their course emphasized memorization than did the flipped classroom group.

    Full Text Available BackgroundProgressive advances in technologies for DNA sequencing and decreasing costs are allowing an easier diffusion of genetic and genomic tests. Physicians’ knowledge and confidence on the topic is often low and not suitable for manage this challenge. Tailored educational programs are required to reach a more and more appropriate use of genetic technologies.MethodsA distance learning course has been created by experts from different Italian medical associations with the support of the Italian Ministry of Health. The course was directed to professional figures involved in prescription and interpretation of genetic tests. A pretest-post-test study design was used to assess knowledge improvement. We analyzed the proportion of correct answers for each question pre and post-test, as well as the mean score difference stratified by gender, age, professional status and medical specialty.ResultsWe reported an improvement in the proportion of correct answers for 12 over 15 questions of the test. The overall mean score to the questions significantly increased in the post-test, from 9.44 to 12.49 (p-value < 0.0001. In the stratified analysis we reported an improvement in the knowledge of all the groups except for geneticists; the pre-course mean score of this group was already very high and did not improve significantly.ConclusionDistance learning is effective in improving the level of genetic knowledge. In the future, it will be useful to analyze which specialists have more advantage from genetic education, in order to plan more tailored education for medical professionals.

    This quantitative, quasi-experimental research investigated if two instructional approaches, the Emporium Computer-Based (Group 2) versus the hands-on approach (Group 1), resulted any difference in student achievement in science for four-year-old prekindergarten students at a private childcare facility in North Carolina. Three research questions hypothesized these relationships: (a) Group 2 versus Group 1 assessed student achievement as theoretically based on Piaget and Vygotsky's perspectives of child development, (b) the instructional approaches related to gender, and (c) the instructional approaches interrelated to ethnicity. Using a two-factor ANOVA and ANCOVA techniques, involved a convenience sample of 126 four-year-old prekindergarten students of which a convenience sample of 126 participated. The Assessment of Measurements for Pre-K (AMP-K), pretest and posttest scores of each group of 63 students measured student achievement. The t tests determined if a significant difference in student achievement existed (dependent variable) with the Emporium Computer-Based versus hands-on instructional approaches (independent variables). The posttest scores of Group 2 (p = 0.00), indicated a significant difference in student achievement. However, gender and ethnicity variables had no effect on student achievement, male (M = 36.14, SD = 19.61) and female (M = 42.91, SD = 18.99) with (p = 0.49), and ethnicity resulted, F (1,125) = 1.65, (p = 0.20). These results suggested that further research on the Emporium Computer-Based instructional approach could improve students' intellectual abilities through more innovative practices.

    Full Text Available Objective: The present research was conducted to study the effect of play therapy on reducing behavioral problems of mal-adjusted children (children with oppositional defiant disorder. Method: By using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected, and among kindergartens of these areas, 3 kindergartens under the support of welfare organization were randomly selected. From pre-school children of these 3 kindergartens, 40 children that could have behavioral disorder according to their teachers and parents complaints, were carefully tested, and among them, by the results obtained from child symptom inventory questionnaire (CSI-4, teacher's form, and a researcher-made self-control checklist, 16 children who showed severe symptoms of oppositional defiant disorder were selected, and they were randomly divided into control and experimental group. This research is quasi-experimental, and is done by the use of pre-test, post-test, and control group. Results: values of calculated F for oppositional defiant disorder in control and experimental group is meaningful after fixing the effect of pre-test (F(1,12=74/94, P<0/001 so there is a meaningful difference between means of disobedience disorder post-test scores in experimental and control group by having the fixed effect of pre-test effect. Comparison of adjusted means of 2 groups shows that the mean of attention-deficit hyperactivity disorder (ADHD in experimental group (M=14/09 is lower than control group (M=36/66. Therefore, applying play therapy in experimental group in comparison with control group, who did not receive these instructions, caused reduction in attention-deficit hyperactivity disorder (ADHD in pre-school children. Conclusion: Results of this research show that the children's disobedience is reduced by benefiting from play therapy.

    It is generally assumed that learning in context increases performance. This study investigates the relationship between the characteristics of a paper-patient context (relevance and familiarity), the mechanisms through which the cognitive dimension of context could improve learning (activation of prior knowledge, elaboration and increasing retrieval cues), and test performance. A total of 145 medical students completed a pretest of 40 questions, of which half were with a patient vignette. One week later, they studied musculoskeletal anatomy in the dissection room without a paper-patient context (control group) or with (ir)relevant-(un)familiar context (experimental groups), and completed a cognitive load scale. Following a short delay, the students completed a posttest. Surprisingly, our results show that students who studied in context did not perform better than students who studied without context. This finding may be explained by an interaction of the participants' expertise level, the nature of anatomical knowledge and students' approaches to learning. A relevant-familiar context only reduced the negative effect of learning the content in context. Our results suggest discouraging the introduction of an uncommon disease to illustrate a basic science concept. Higher self-perceived learning scores predict higher performance. Interestingly, students performed significantly better on the questions with context in both tests, possibly due to a 'framing effect'. Since studies focusing on the physical and affective dimensions of context have also failed to find a positive influence of learning in a clinically relevant context, further research seems necessary to refine our theories around the role of context in learning.

    Pre-training evaluation and feedback have been shown to improve medical students' skills acquisition of basic life support (BLS) immediately following training. The impact of such training on BLS skills retention is unknown. This study was conducted to investigate effects of pre-training evaluation and feedback on BLS skills retention in medical students. Three hundred and thirty 3rd year medical students were randomized to two groups, the control group (C group) and pre-training evaluation and feedback group (EF group). Each group was subdivided into four subgroups according to the time of retention-test (at 1-, 3-, 6-, 12-month following the initial training). After a 45-min BLS lecture, BLS skills were assessed (pre-training evaluation) in both groups before training. Following this, the C group received 45 min training. 15 min of group feedback corresponding to students' performance in pre-training evaluation was given only in the EF group that was followed by 30 min of BLS training. BLS skills were assessed immediately after training (post-test) and at follow up (retention-test). No skills difference was observed between the two groups in pre-training evaluation. Better skills acquisition was observed in the EF group (85.3 ± 7.3 vs. 68.1 ± 12.2 in C group) at post-test (p<0.001). In all retention-test, better skills retention was observed in each EF subgroup, compared with its paired C subgroup. Pre-training evaluation and feedback improved skills retention in the EF group for 12 months after the initial training, compared with the control group. Copyright © 2013 Elsevier Ireland Ltd.

    This study compared the effectiveness of three approaches to improving visual perception among preschool children 4-6 years old with developmental delays: multimedia visual perceptual group training, multimedia visual perceptual individual training, and paper visual perceptual group training. A control group received no special training. This study employed a pretest-posttest control group of true experimental design. A total of 64 children 4-6 years old with developmental delays were randomized into four groups: (1) multimedia visual perceptual group training (15 subjects); (2) multimedia visual perceptual individual training group (15 subjects); paper visual perceptual group training (19 subjects); and (4) a control group (15 subjects) with no visual perceptual training. Forty minute training sessions were conducted once a week for 14 weeks. The Test of Visual Perception Skills, third edition, was used to evaluate the effectiveness of the intervention. Paired-samples t-test showed significant differences pre- and post-test among the three groups, but no significant difference was found between the pre-test and post-test scores among the control group. ANOVA results showed significant differences in improvement levels among the four study groups. Scheffe post hoc test results showed significant differences between: group 1 and group 2; group 1 and group 3; group 1 and the control group; and group 2 and the control group. No significant differences were reported between group 2 and group 3, and group 3 and the control group. The results showed all three therapeutic programs produced significant differences between pretest and posttest scores. The training effect on the multimedia visual perceptual group program and the individual program was greater than the developmental effect Both the multimedia visual perceptual group training program and the multimedia visual perceptual individual training program produced significant effects on visual perception.

    Long-term care institutions have become an option for older people who are dependent in daily living. However, insufficient attention has been focused on assessing the life satisfaction of those currently residing in these institutions in Taiwan. Previous research indicates that group reminiscence may improve the life satisfaction of older adults. However, there is currently no consensus regarding the implementation and evaluation of reminiscence interventions. To examine the effect of a structured group reminiscence protocol on the life satisfaction of institutionalized older adults. The study used a quasi-experimental design. A total of 48 older adults were conveniently recruited from two long-term care institutions in southern Taiwan. The experimental group (n = 23) received 8 weeks of structured-group reminiscence for 40 minutes weekly, while the control group (n = 25) received routine care from the institution. Both groups were evaluated using a life-satisfaction questionnaire before and after the intervention and again four weeks later. Life satisfaction scores were statistically similar on the pre-test and significantly different on both post-test questionnaires for the two groups. The scores for the experimental and control groups were pre-test: 24.22 vs 23.36 (p = .063); post-test I: 27.22 vs 23.32 (p < .001); and post-test II: 26.43 vs 23.00 (p < .001). The mean post-test scores for the experimental group were significantly higher than the pre-test score (p < .001). The generalized estimating equation test showed that the overall score of life satisfaction for the experimental group increased by 0.85-points (p = .042) more than the control group, which is a significant difference. The results support that the 8-week structured group reminiscence protocol effectively enhances life satisfaction in older adults. The results of this study may be referenced in the continuing education of nurses working in long-term care institutions in the context of helping

    Pre-eclampsia is an important cause of maternal morbidity and mortality. Its etiology is still unknown. Clinical symptoms correlate with activation of coagulation and inherited thrombophilia has been associated with pre-eclampsia. ABO blood group has been associated with thrombotic disorders and pre-eclampsia. We assessed ABO blood group, seven thrombophilia associated polymorphisms, and anti-beta2-glycoprotein I antibodies as risk factors for pre-eclampsia. We performed a population-based nested case-control study of 100,000 consecutive pregnancies in Finland. Cases and controls were identified by combining national registers and medical records were reviewed. We studied 248 cases fulfilling strict criteria for pre-eclampsia and 679 controls. Severe pre-eclampsia, early pre-eclampsia, and pre-eclampsia with intra-uterine growth restriction (IUGR) were analyzed separately. Blood group AB increased the risk for pre-eclampsia as a whole (OR 2.1, 95% CI 1.3-3.5), and in the three subgroups (OR 2.3, 3.8, 3.4; 95% CI 1.3-3.9, 2.0-7.1, 1.6-7.1). FV Leiden increased the risk as a whole (OR 1.7, 95% CI 0.8-3.9), and in the three subgroups, although not statistically significantly. Anti-beta2-glycoprotein I antibodies were not associated with pre-eclampsia. High body mass index, diabetes, first pregnancy, and twin pregnancy increased the risk from 1.5-fold to 8.2-fold. Our results confirm and extend the prior observation of blood group AB being a risk factor for pre-eclampsia. ABO blood group is known from all pregnant women. The value of blood group as risk factor for pre-eclampsia should be further assessed in prospective studies. In this study, FV Leiden was not statistically significant risk factor.

    Factors previously shown to influence patient care include effective decision making, team work, evidence based practice, staffing and job satisfaction. Clinical rounds have the potential to optimise these factors and impact on patient outcomes, but use of this strategy by intensive care nurses has not been reported. To determine the effect of implementing Nursing Rounds in the intensive care environment on patient care planning and nurses' perceptions of the practice environment and work satisfaction. Pre-test post-test 2 group comparative design. Two intensive care units in tertiary teaching hospitals in Australia. A convenience sample of registered nurses (n=244) working full time or part time in the participating intensive care units. Nurses in participating intensive care units were asked to complete the Practice Environment Scale-Nursing Work Index (PES-NWI) and the Nursing Worklife Satisfaction Scale (NWSS) prior to and after a 12 month period during which regular Nursing Rounds were conducted in the intervention unit. Issues raised during Nursing Rounds were described and categorised. The characteristics of the sample and scale scores were summarised with differences between pre and post scores analysed using t-tests for continuous variables and chi-square tests for categorical variables. Independent predictors of the PES-NWI were determined using multivariate linear regression. Nursing Rounds resulted in 577 changes being initiated for 171 patients reviewed; these changes related to the physical, psychological--individual, psychological--family, or professional practice aspects of care. Total PES-NWI and NWSS scores were similar before and after the study period in both participating units. The NWSS sub-scale of interaction between nurses improved in the intervention unit during the study period (pre--4.85±0.93; post--5.36±0.89, p=0.002) with no significant increase in the control group. Factors independently related to higher PES-NWI included

    Full Text Available In recent years, a number of studies have been conducted with regard to communication strategy training and performance on communicative tasks (Lam, 2009; Nakatani, 2010; Naughton, 2006. This study aims to add to the literature by examining how two strategies, clarifying/confirming and extending a conversation, and two methods of teaching the strategies, affected the interactional sequences and overall group discussion performance of EFL students at a university in Japan. Pre and posttreatment small-group discussions were recorded for assessment, and a stimulated recall interview was administered to determine the participants’ perceptions of their learning and language use. Posttest results reveal that the experimental groups that were taught predetermined phrases aimed at clarifying/confirming and extending a conversation employed such phrases more frequently than the control group. However, this employment of phrases did not lead to higher gains in group discussion skills as the control group enjoyed the largest gains from pre to posttest. The researchers consider the findings in light of previous research, and conclude with recommendations for future research on the topic with special regard to research design.

    Dental hygiene education continues to move beyond mastery of content material and skill development to learning concepts that promote critical-thinking and problem-solving skills. The purpose of this research was to evaluate the effectiveness of collaborative learning and determine the growth in intellectual development of 54 first-year dental hygiene students. The control group used traditional pre-clinical teaching and the experimental group used collaborative pedagogy for instrument introduction. All students were subjected to a post-test evaluating their ability to apply the principles of instrumentation. Intellectual development was determined using pre- and post-tests based on the Perry Scheme of Intellectual Development. Student attitudes were assessed using daily Classroom Assessment Activities and an end-of-semester departmental course evaluation. Findings indicated no significant difference between collaborative learning and traditional learning in achieving pre-clinical competence as evidenced by the students' ability to apply the principles of instrumentation. Advancement in intellectual development did not differ significantly between groups. Value added benefits of a collaborative learning environment as identified by the evaluation of student attitudes included decreased student reliance on authority, recognition of peers as legitimate sources of learning and increased self-confidence. A significant difference in student responses to daily classroom assessments was evident on the 5 days a collaborative learning environment was employed. Dental hygiene students involved in a pre-clinical collaborative learning environment are more responsible for their own learning and tend to have a more positive attitude toward the subject matter. Future studies evaluating collaborative learning in clinical dental hygiene education need to investigate the cost/benefit ratio of the value added outcomes of collaborative learning.

    The Jewish community has traditionally taken ownership of its health, and has taken great strides to raise awareness about genetic issues that affect the community, such as Tay-Sachs disease and Hereditary Breast and Ovarian Cancer syndrome. Thanks in part to these heightened awareness efforts, many Orthodox Jewish individuals are now using genetics services as they begin to plan their families. Due to unique cultural and religious beliefs and perceptions, the Orthodox Jewish patients who seek genetic counseling face many barriers to a successful counseling session, and often seek the guidance of programs such as the Program for Jewish Genetic Health (PJGH). In this article, we present clinical vignettes from the PJGH's clinical affiliate, the Reproductive Genetics practice at the Montefiore Medical Center. These cases highlight unique features of contemporary premarital counseling and screening within the Orthodox Jewish Community, including concerns surrounding stigma, disclosure, "marriageability," the use of reproductive technologies, and the desire to include a third party in decision making. Our vignettes demonstrate the importance of culturally-sensitive counseling. We provide strategies and points to consider when addressing the challenges of pre- and post-test counseling as it relates to genetic testing in this population.

    Full Text Available Abstract Background Many newly screened people living with HIV (PLHIV in Sub-Saharan Africa do not understand the importance of regular pre-antiretroviral (ARV care because most of them have been counseled by staff who lack basic counseling skills. This results in low uptake of pre-ARV care and late treatment initiation in resource-poor settings. The effect of providing post-test counseling by staff equipped with basic counseling skills, combined with home visits by community support agents on uptake of pre-ARV care for newly diagnosed PLHIV was evaluated through a randomized intervention trial in Uganda. Methods An intervention trial was performed consisting of post-test counseling by trained counselors, combined with monthly home visits by community support agents for continued counseling to newly screened PLHIV in Iganga district, Uganda between July 2009 and June 2010, Participants (N = 400 from three public recruitment centres were randomized to receive either the intervention, or the standard care (the existing post-test counseling by ARV clinic staff who lack basic training in counseling skills, the control arm. The outcome measure was the proportion of newly screened and counseled PLHIV in either arm who had been to their nearest health center for clinical check-up in the subsequent three months +2 months. Treatment was randomly assigned using computer-generated random numbers. The statistical significance of differences between the two study arms was assessed using chi-square and t-tests for categorical and quantitative data respectively. Risk ratios and 95% confidence intervals were used to assess the effect of the intervention. Results Participants in the intervention arm were 80% more likely to accept (take up pre-ARV care compared to those in the control arm (RR 1.8, 95% CI 1.4-2.1. No adverse events were reported. Conclusions Provision of post-test counseling by staff trained in basic counseling skills, combined with home visits by

    Full Text Available Abstract Background One potential concern with using mailed surveys containing trauma-related content is the possibility of re-traumatizing survivors without a trained mental health professional present. Prior research provides insufficient guidance regarding the prevalence and magnitude of this risk because the psychological harms of trauma-related surveys have typically been estimated using single post-test observations. Post-test observations cannot quantify magnitude of change in participants’ emotional states and may over or under estimate associations between participants’ characteristics (risk factors and post-survey upset. Methods We conducted two pre- and post-test studies in samples of former applicants for posttraumatic stress disorder disability benefits: 191 males who served during Gulf War I plus 639 male and 921 female Veterans who served sometime between 1955 and 1998. We used two 9-point items from the Self-Assessment Manikins to measure participants’ valence (sadness/happiness and arousal (tenseness/calmness before and after they completed mailed surveys asking about trauma-related symptoms or experiences. We examined the following potential predictors for post-survey sadness and tenseness: screening positive for posttraumatic stress disorder, having a serious mental illness, and history of military sexual assault or combat. Results After the survey, across the groups, 29.3–41.8% were sadder, 45.3–52.2% had no change in valence, and 12.9–22.5% were happier; 31.7–40.2% were tenser, 40.6–48.2% had no change in arousal, and 17.3–24.0% were calmer. The mean increase in sadness or tenseness post-survey was less than one point in all groups (SD’s < 1.7. Cohen’s d ranged from 0.07 to 0.30. Most hypothesized predictors were associated with greater baseline sadness or tenseness, but not necessarily with larger post-survey changes. Women with a history of military sexual assault had the largest net post

Previous studies of SBML for NTHC-insertion have been conducted at a local level. Objectives: Determine if SBML for NTHC-insertion can be effective when provided at a national continuing medical education (CME meeting. Describe the correlation of demographic factors, prior experience with NTHC-insertion and procedural self-confidence with simulated performance of the procedure. Design: Pre-test – post-test study. Setting: 2014 Canadian Society of Nephrology annual meeting. Participants: Nephrology fellows, internal medicine residents and medical students. Measurements: Participants were surveyed regarding demographics, prior NTHC-insertion experience, procedural self-confidence and attitudes regarding the training they received. NTHC-insertion skills were assessed using a 28-item checklist. Methods: Participants underwent a pre-test of their NTHC-insertion skills at the internal jugular site using a realistic patient simulator and ultrasound machine. Participants then had a training session that included a didactic presentation and 2 hours of deliberate practice using the simulator. On the following day, trainees completed a post-test of their NTHC-insertion skills. All participants were required to meet or exceed a minimum passing score (MPS previously set at 79%. Trainees who did not reach the MPS were required to perform more deliberate practice until the MPS was achieved. Results: Twenty-two individuals participated in SBML training. None met or exceeded the MPS at baseline with a median checklist score of 20 (IQR, 7.25 to 21. Seventeen of 22 participants (77% completed post-testing and improved their scores to a median of 27 (IQR, 26 to 28; p < 0.001. All met or exceeded the MPS on their first attempt.

    Simulation-based-mastery-learning (SBML) is an effective method to train nephrology fellows to competently insert temporary, non-tunneled hemodialysis catheters (NTHCs). Previous studies of SBML for NTHC-insertion have been conducted at a local level. Determine if SBML for NTHC-insertion can be effective when provided at a national continuing medical education (CME) meeting. Describe the correlation of demographic factors, prior experience with NTHC-insertion and procedural self-confidence with simulated performance of the procedure. Pre-test - post-test study. 2014 Canadian Society of Nephrology annual meeting. Nephrology fellows, internal medicine residents and medical students. Participants were surveyed regarding demographics, prior NTHC-insertion experience, procedural self-confidence and attitudes regarding the training they received. NTHC-insertion skills were assessed using a 28-item checklist. Participants underwent a pre-test of their NTHC-insertion skills at the internal jugular site using a realistic patient simulator and ultrasound machine. Participants then had a training session that included a didactic presentation and 2 hours of deliberate practice using the simulator.

    Surgical procedures are complex motion sequences that require a high level of preparation, training, and concentration. In recent years, Internet platforms providing surgical content have been established. Used as a surgical training method, the effect of multimedia-based training on practical surgical skills has not yet been evaluated. This study aimed to evaluate the effect of multimedia-based training on surgical performance. A 2 × 2 factorial, randomized controlled trial with a pre- and posttest design was used to test the effect of multimedia-based training in addition to or without practical training on 70 participants in four groups defined by the intervention used: multimedia-based training, practical training, and combination training (multimedia-based training + practical training) or no training (control group). The pre- and posttest consisted of a laparoscopic cholecystectomy in a Pelvi-Trainer and was video recorded, encoded, and saved on DVDs. These were evaluated by blinded raters using a modified objective structured assessment of technical skills (OSATS). The main evaluation criterion was the difference in OSATS score between the pre- and posttest (ΔOSATS) results in terms of a task-specific checklist (procedural steps scored as correct or incorrect). The groups were homogeneous in terms of demographic parameters, surgical experience, and pretest OSATS scores. The ΔOSATS results were highest in the multimedia-based training group (4.7 ± 3.3; p Multimedia-based training improved surgical performance significantly and thus could be considered a reasonable tool for inclusion in surgical curricula.

    Endotel dysfunction, vasoconstriction, and oxidative stress are described in the pathophysiology of pre-eclampsia, but its aetiology has not been revealed clearly. To examine whether there is a difference between the placentas of pre-eclamptic pregnant women and those of a control group in terms of their T2 star values. Case-control study. Twenty patients diagnosed with pre-eclampsia and 22 healthy controls were included in this study. The placentas obtained after births performed via Caesarean section were taken into the magnetic resonance imaging area in plastic bags within the first postnatal hour, and imaging was performed via modified DIXON-Quant sequence. Average values were obtained by performing T2 star measurements from four localisations on the placentas. T2 star values measured in the placentas of the control group were found to be significantly lower than those in the pre-eclampsia group (pstar value in the pre-eclamptic group was found to be 37.48 ms (standard deviation ± 11.3), this value was 28.74 (standard deviation ± 8.08) in the control group. The cut-off value for the T2 star value, maximising the accuracy of diagnosis, was 28.59 ms (area under curve: 0.741; 95% confidence interval: 0.592-0.890); sensitivity and specificity were 70% and 63.6%, respectively. This study, the T2 star value, which is an indicator of iron amount, was found to be significantly lower in the control group than in the pre-eclampsia group. This may be related to the reduction in blood flow to the placenta due to endothelial dysfunction and vasoconstriction, which are important in pre-eclampsia pathophysiology.

    The global environmental crisis intensifies particularly in developing nations. Environmental educators have begun to understand that changing the environmental impact requires not only changes in pro-environmental knowledge and attitudes but also in associated, self-determined motivation. This study was designed to test the hypothesis that a green chemistry curriculum changes Malaysian pre-service teachers' environmental motivation. Two comparable groups of pre-service teachers participated in this study. The students in the experimental group ( N = 140) did green chemistry experiments whereas the control group ( N = 123) did equivalent experiments in a traditional manner. Posttest results indicate that there is significant difference between both the groups for intrinsic motivation, integration, identification, and introjections scales and no differences for external regulation and amotivation scales. The qualitative analysis of interview data suggests that the changes are predominantly due to the personal satisfaction that participants derived from engaging in pro-environmental behavior.

    Full Text Available This research was done to analyze the effects of Coping with Burnout Program, developed on the basis of Solution-Focused Brief Therapy on the burnout levels of university students. To select the subjects that would participate in the research, Maslach Burnout Inventory­­–Student Survey was applied on 461 university students from the University of Sakarya. As a result of pre-interviews, 24 students who had experienced student burnout voluntarily participated in a Coping with Burnout Program. The students were randomly appointed to one of the experimental and control groups. At this stage, a six-session Coping with Burnout Program developed by the researcher was applied on the students from the experimental group. No application was performed on the students from the control group. A 2x3 design (experimental/ control groups X pretest/ posttest/ follow up was used in the research. The scores from the Maslach Burnout Inventory–Student Survey formed the dependent variable of the research, and the application of Coping with Burnout Program formed the independent variable of the research. The scale used in the research was applied on the groups as pretest two weeks before the sessions started, and as posttest two weeks after the sessions ended, and as follow-up two months after the posttest in order to determine the resistance of the experimental process. In the analysis of the data obtained through these processes, two-way analysis of variance (ANOVA was used to determine whether or not there was a significant difference between groups and the survey. The data obtained through the research proved that the Coping with Burnout Program decreased the burnout levels of the students in the experimental group as were determined with the Maslach Burnout Inventory–Student Survey, and follow up tests showed that the situation remained the same.

    Full Text Available Reading comprehension is one of the most important skills, especially in the EFL context. One way to improve reading comprehension is through strategy use. The present study aimed at investigating the effect of question-generation strategy on learners' reading comprehension. The participants in the study were 63 intermediate students from three intact groups in Resa institute in Boukan, They were randomly assigned to two experimental and one control groups. They were given two samples of the reading section of the standardized Preliminary English Test (PET as the pre- and post-tests. The students in the experimental group A generated text-based reading comprehension questions individually, and in the experimental group B  in groups of three but the learners in the control group answered the reading comprehension questions provided in the text. The results of ANOVA revealed that the students in the experimental group B, who employed group-question generation strategy, outperformed the experimental group A, who employed individual- question generation strategy and the control group in the reading comprehension post-test. The findings can have some implications for EFL teachers and syllabus designers.

    e-learning resources may be beneficial for complex or conceptually difficult topics. Leukaemia is one such topic, yet there are no reports on the efficacy of e-learning for leukaemia. This study compared the learning impact on senior medical students of a purpose-built e-learning module on leukaemia, compared with existing online resources. A randomised controlled trial was performed utilising volunteer senior medical students. Participants were randomly allocated to Study and Control groups. Following a pre-test on leukaemia administered to both groups, the Study group was provided with access to the new e-learning module, while the Control group was directed to existing online resources. A post-test and an evaluation questionnaire were administered to both groups at the end of the trial period. Study and Control groups were equivalent in gender distribution, mean academic ability, pre-test performance and time studying leukaemia during the trial. The Study group performed significantly better than the Control group in the post-test, in which the group to which the students had been allocated was the only significant predictor of performance. The Study group's evaluation of the module was overwhelmingly positive. A targeted e-learning module on leukaemia had a significant effect on learning in this cohort, compared with existing online resources. We believe that the interactivity, dialogic feedback and integration with the curriculum offered by the e-learning module contributed to its impact. This has implications for e-learning design in medicine and other disciplines.

This study aimed to assess the feasibility of offering a 6-week parenting program for mothers of pre-school children attending family health centres (FHCs in Karachi, the largest metropolitan city of Pakistan. Methods A pilot quasi-experimental trial was conducted. Two FHCs were selected, one as the intervention and the second as the control. A total of 57 mothers of pre-school children (n = 30 intervention; n = 27 control participated in this study. Mothers in the intervention group received SOS Help for parents module, while mothers in the control group received information about routine childcare. A parenting scale (PS was administered before the program was implemented and repeated 2 weeks after the program was completed in both groups. Statistical analysis was performed to compare participants’ attributes. Descriptive analysis was conducted to compare pre- and post-test mean scores along with standard deviation for parenting subscales in the intervention and control groups. Results A total of 50 mothers (n = 25 intervention; n = 25 control completed the 6-week program. Attrition was observed as 5/30 (17% in the intervention arm and 2/27 (2% in the control arm. Mothers commonly reported the burden of daily domestic and social responsibilities as the main reason for dropping out. Furthermore, the majority of participants in the control group recommended increasing the duration of weekly sessions from 1 to 1.5 hours, thereby decreasing the program period from 6 to 4 weeks. Mothers in intervention group reported substantial improvement in parenting skills as indicated by mean difference in their pre- and post-test scores for laxness and over

    It has been planned to give pre-clinical practice in the clinic, so-called inclusive clinical practice phase I, for fifth-grade students in the School of Dentistry, Faculty of Dentistry, Tokyo Medical and Dental University, to give them the clinical training needed to perform dental practice and clinical practicum for comprehensive patient care, namely inclusive clinical practice phase II. This study analyzed the educative efficiency of the class on nosocomial infection control (NIC) by comparing achievements pre- and post-test, and discussed appropriate education planning on the NIC for dental students. Sixty-two fifth-grade students in the 2007 academic year sat the pre- and post-tests; the mean score and standard deviation of these tests were 5.30 +/- 1.26 (n = 56) and 8.59 +/- 1.18 (n = 59), respectively. There was a statistically significant difference between them (paired t-test, p < 0.01). Another finding was that students with high scores in the post-test did not necessarily achieve high ratings in the pre-test. It is suggested that the introduction of pre- and post-tests and the clarification of main points in the class as a theme of NIC could be a useful tool for increasing the comprehension of students on the theme. Since students at lower grades will attend clinical practice in the university hospital, it is thought that students should be given NIC training early in the clinical course, and the current curriculum should be improved to increase the opportunity for students to study this important issue.

    Full Text Available Speaking is an important skill in language learning and EFL learners sometimes face difficulties when they want to speak. This study attempted to measure the effect of Kagan’s cooperative structures on speaking skill of Iranian EFL learners. The participants were selected from EFL learners studying at Ideal Language Institute. The Cambridge English Language Assessment was administered in order to select homogenous participants. Forty eight adult female EFL learners were selected as intermediate learners based on their results of the language proficiency test. They were divided into two groups, 24 as the control group and 24 as the experimental group. A pre-test was administered to both groups at the beginning of the experiment then, the students participated in 90 minute classes two times a week for eight sessions. At the end of the experiment, a post-test was assigned to both groups to determine whether the Kagan’s cooperative structures had positively affected the students’ speaking skills. The normality of data was tested through Skewness, Kurtosis, and K-S. To make sure the participants were homogenous, the parametric statistical technique of independent -samples t-test was calculated between the pre-tests of both groups and they were homogenous. Independent-samples t-test between the posttests of the experimental group and the control group was calculated and it showed that the participants of the experimental group outperformed the subjects of the control group. Moreover, paired-samples ttest between the pre-test and post-test of the experimental group was calculated and it was shown that the experimental participants progressed from the pre-test to the post-test. The study revealed that: (1 Kagan’s cooperative structures had a positive effect on the students’ speaking skills, (2 the experimental group obtained higher scores in the post-test than in the pre-test, making the difference between the pre-test and post-test scores

    Full Text Available Morphological Awareness (henceforth: MA, defined as the ability to understand the morphemic structure of the words, has been reported to affect various aspects of second language performance including reading comprehension ability, spelling performance, etc. Yet, the concept has been far less treated with reference to l2 listening transcription. Thus, against this background, this study aims to investigate the link between MA and listening transcription ability of Iranian pre-university students. To this aim, 40 pre-university students participated in the study, and were assigned to two control and experimental groups. Both groups were first given three short listening passages to transcribe as the pre-tests. The results of the independent-samples t-test revealed no significant difference between the two groups. The experimental group, then, received five one-hour sessions briefing them on the morphological realization of English words. The two groups were then given three short listening passages to transcribe as their post-tests. The results of the independent-samples t-tests attested to the significant difference between the two groups, thus, supporting the relationship between MA and listening transcription ability. The study concludes with some suggestions as to the incorporation of MA into L2 learning programs.

    Full Text Available Discovery Learning can be defined as the learning that takes place when the student is not presented with subject matter in the final form, rather he/she is required to find out the concepts by him/her self. This research aims to describe and analyze discovery learning method to strategically improve the comprehension and reasoning ability of Arabic pre-service teachers, which can motivate and enhance their creativity in order to enrich their insight about Arabic teaching as well, especially those who are in training centre. This research was undertaken in two classes of Makassar Religious Training Centre during June-August 2016. The design of this research is experiment with discovery learning approach with randomized pretest-posttest control group design. It was done randomly when to choosing the participants to be experiment and control group. Based on hypothesis testing, discovery learning has positive effects on the pre-service teachers’ Arabic ability in training centre to understand and analyze Arabic. Therefore, based on two-variance analysis; control and experiment group, there is difference on teachers’ comprehension and reasoning ability in learning Arabic between experiment and control group by using discovery learning and conventional method.

    Full Text Available Abstract Background e-learning resources may be beneficial for complex or conceptually difficult topics. Leukaemia is one such topic, yet there are no reports on the efficacy of e-learning for leukaemia. This study compared the learning impact on senior medical students of a purpose-built e-learning module on leukaemia, compared with existing online resources. Methods A randomised controlled trial was performed utilising volunteer senior medical students. Participants were randomly allocated to Study and Control groups. Following a pre-test on leukaemia administered to both groups, the Study group was provided with access to the new e-learning module, while the Control group was directed to existing online resources. A post-test and an evaluation questionnaire were administered to both groups at the end of the trial period. Results Study and Control groups were equivalent in gender distribution, mean academic ability, pre-test performance and time studying leukaemia during the trial. The Study group performed significantly better than the Control group in the post-test, in which the group to which the students had been allocated was the only significant predictor of performance. The Study group’s evaluation of the module was overwhelmingly positive. Conclusions A targeted e-learning module on leukaemia had a significant effect on learning in this cohort, compared with existing online resources. We believe that the interactivity, dialogic feedback and integration with the curriculum offered by the e-learning module contributed to its impact. This has implications for e-learning design in medicine and other disciplines.

    Preliminary posttest analyses have been completed on optical specimens exposed during the Omega II test series conducted on 14 July 2006. The Omega Facility, located at the Laboratory for Laser Energetics (LLE) at the University of Rochester was used to produce X-ray environments through the interaction of intense pulsed laser radiation upon germanium-loaded silica aerogels. The optical specimen testing was supported by GH Systems through experiment design, pre- and post-test analyses, specimen acquisition, and overall technical experience. The test specimens were fabricated and characterized by Surface Optics Corporation (SOC), San Diego, CA and were simple protected gold coatings on silica substrates. Six test specimens were exposed, five filtered with thin beryllium foil filters, and one unfiltered which was exposed directly to the raw environment. The experimental objectives were: (1) demonstrate that tests of optical specimens could be performed at the Omega facility; (2) evaluate the use and survivability of beryllium foil filters as a function of thickness; (3) obtain damage data on optical specimens which ranged from no damage to damage; (4) correlate existing thermal response models with the damage data; (5) evaluate the use of the direct raw environment upon the specimen response and the ability/desirability to conduct sensitive optical specimen tests using the raw environment; and (6) initiate the development of a protocol for performing optical coatings/mirror tests. This report documents the activities performed by GH Systems in evaluating and using the environments provided by LLNL, the PUFFTFT analyses performed using those environments, and the calculated results compared to the observed and measured posttest data

    Pre-exam anxiety syndrome is a common condition occurring in pre-exam students and directly affects their examination performance and physical state. Wrist-ankle acupuncture has significant therapeutic effects in treating mental disorders and may also relieve the symptoms of pre-exam anxiety syndrome. To assess the therapeutic effect of wrist-ankle acupuncture on pre-exam anxiety syndrome. A total of 60 students who met the inclusion criteria of pre-exam anxiety syndrome were enrolled from a university in Shanghai and they were randomly divided into treatment group and control group. There were 30 cases in each group, and no case failed to follow-up. In the treatment group, wrist-ankle acupuncture was adopted to point upper 1 bilaterally (impression between flexor carpi ulnaris tendon and ulnar margin), and there was no requirement for Deqi (arrival of qi). In the control group, sham acupuncture was adopted. The treatment was applied 3 times totally in both groups one week before the exam, once every other day, each time with the needles retained for 30 min. The therapeutic effects were compared between two groups. Before and after 3 treatments, Sarason Test Anxiety Scale (TAS) and Expectation and Treatment Credibility Scale (ETCS) were measured and evaluated. The therapeutic effect experienced by the treatment group was better than that of the control group (PETCS before treatment between the two groups. The scores of TAS after treatment in two groups were higher than those before treatment (PETCS than those in the control group (P<0.05, P<0.01). No adverse reaction was reported. Wrist-ankle acupuncture can relieve the symptoms of pre-exam anxiety syndrome significantly, and this therapy is highly safe.

    People with sickle cell disease (SCD) or sickle cell trait (SCT) may not have information about genetic inheritance needed for making informed reproductive health decisions. CHOICES is a Web-based, multimedia educational intervention that provides information about reproductive options and consequences to help those with SCD or SCT identify and implement an informed parenting plan. Efficacy of CHOICES compared with usual care must be evaluated. The purpose was to compare immediate posttest effects of CHOICES versus an attention-control usual care intervention (e-Book) on SCD-/SCT-related reproductive health knowledge, intention, and behavior. In a randomized controlled study, we recruited subjects with SCD/SCT from clinics, community settings, and online networks with data collected at sites convenient to the 234 subjects with SCD (n = 136) or SCT (n = 98). Their ages ranged from 18 to 35 years; 65% were women, and 94% were African American. Subjects completed a measure of sickle cell reproductive knowledge, intention, and behavior before and immediately after the intervention. Compared with the e-Book group, the CHOICES group had significantly higher average knowledge scores and probability of reporting a parenting plan to avoid SCD or SCD and SCT when pretest scores were controlled. Effects on intention and planned behavior were not significant. The CHOICES group showed significant change in their intention and planned behavior, whereas the e-Book group did not show significant change in their intention, but their planned behavior differed significantly. Initial efficacy findings are encouraging but warrant planned booster sessions and outcome follow-ups to determine sustained intervention efficacy on reproductive health knowledge, intention, and actual behavior of persons with SCD/SCT.

    Multiple training modalities for laparoscopy have different advantages, but little research has been conducted on the benefit of a training program that includes multiple different training methods compared to one method only. This study aimed to evaluate benefits of a combined multi-modality training program for surgical residents. Laparoscopic cholecystectomy (LC) was performed on a porcine liver as the pre-test. Randomization was stratified for experience to the multi-modality Training group (12 h of training on Virtual Reality (VR) and box trainer) or Control group (no training). The post-test consisted of a VR LC and porcine LC. Performance was rated with the Global Operative Assessment of Laparoscopic Skills (GOALS) score by blinded experts. Training (n = 33) and Control (n = 31) were similar in the pre-test (GOALS: 13.7 ± 3.4 vs. 14.7 ± 2.6; p = 0.198; operation time 57.0 ± 18.1 vs. 63.4 ± 17.5 min; p = 0.191). In the post-test porcine LC, Training had improved GOALS scores (+ 2.84 ± 2.85 points, p < 0.001), while Control did not (+ 0.55 ± 2.34 points, p = 0.154). Operation time in the post-test was shorter for Training vs. Control (40.0 ± 17.0 vs. 55.0 ± 22.2 min; p = 0.012). Junior residents improved GOALS scores to the level of senior residents (pre-test: 13.7 ± 2.7 vs. 18.3 ± 2.9; p = 0.010; post-test: 15.5 ± 3.4 vs. 18.8 ± 3.8; p = 0.120) but senior residents remained faster (50.1 ± 20.6 vs. 25.0 ± 1.9 min; p < 0.001). No differences were found between groups on the post-test VR trainer. Structured multi-modality training is beneficial for novices to improve basics and overcome the initial learning curve in laparoscopy as well as to decrease operation time for LCs in different stages of experience. Future studies should evaluate multi-modality training in comparison with single modalities. German Clinical Trials Register DRKS00011040.

    Full Text Available Adolescents are in a high-risk period developmentally, in terms of susceptibility to stress. A mindfulness intervention represents a potentially useful strategy for developing cognitive and emotion regulation skills associated with successful stress coping. Mindfulness strategies have been used successfully for emotional coping in adults, but are not as well studied in youth. This article details a novel proposal for the design of an 8-week randomized study to evaluate a high school-based mindfulness curriculum delivered as part of a two semester health class. A wellness education intervention is proposed as an active control, along with a waitlist control condition. All students enrolled in a sophomore (10th grade health class at a private suburban high school will be invited to participate (n = 300. Pre-test assessments will be obtained by youth report, parent ratings, and on-site behavioral testing. The assessments will evaluate baseline stress, mood, emotional coping, controlled attention, and working memory. Participants, divided into 13 classrooms, will be randomized into one of three conditions, by classroom: A mindfulness intervention, an active control (wellness education, and a passive control (waitlist. Waitlisted participants will receive one of the interventions in the following term. Intervention groups will meet weekly for 8 weeks during regularly scheduled health classes. Immediate post-tests will be conducted, followed by a 60-day post-test. It is hypothesized that the mindfulness intervention will outperform the other conditions with regard to the adolescents' mood, attention and response to stress.

METHOD: Pre-test were applied to parents of 21 children with benign epilepsy of childhood recently diagnosed, from 5 to 15 years, who participated in the groups at HC/Unicamp. There was a presentation of an educational video, discussion and application of the post-test 1. After six months, the post-test 2 was applied. RESULTS: The beliefs were: fear of swallowing the tongue during the seizures (76.19% and of a future mental disease (66.67%. Facing the epilepsy, fear and sadness appeared. 76.19% of the parents presented overprotection and 90.48%, expected a new seizure. In the post-test 1, the parents affirmed that the information offered had modified the beliefs. In the post-test 2, 80.95% didn't report great doubts about epilepsy and 90.48% considered their relationship with their children better. CONCLUSIONS: The demystification of beliefs supplied from the groups influenced the family positively, prevented behavior alterations and guaranteed effective care in the attendance to the child with epilepsy.

The study was quasi-experimental and utilized a pretest-posttest design for both experimental and control groups. Eighth grade female and male students from three schools in a large northeastern school district participated in this study. The achievement test consisted of 10 multiple choice and two open-response questions and used questions from state-wide and national assessments as well as teacher-constructed items. A 29 item Likert type instrument (McMillan, 1992) was administered to measure science self-efficacy and attitude toward science. The study was of 12 weeks duration. During the study, experimental group students were asked to perform collaborative concept map construction in single sex dyads using specific terms designated by the classroom teacher and the researcher. During classroom visitations, student perceptions of collaborative concept mapping were collected and were used to provide insight into the results of the quantitative data analysis. Data from the pre and posttest instruments were analyzed for both experimental and control groups using t-tests. Additionally, the three teachers were interviewed and their perceptions of the study were also used to gain insight into the results of the study. The analysis of data showed that experimental group females showed significantly higher gains in achievement than control group females. An additional analysis of data showed experimental group males showed significantly greater gains in

    Mental health complaints are quite common in health care employees and can have adverse effects on work functioning. The aim of this study was to evaluate an e-mental health (EMH) approach to workers' health surveillance (WHS) for nurses and allied health professionals. Using the waiting-list group of a previous randomized controlled trial with high dropout and low compliance to the intervention, we studied the pre- and posteffects of the EMH approach in a larger group of participants. We applied a pretest-posttest study design. The WHS consisted of online screening on impaired work functioning and mental health followed by online automatically generated personalized feedback, online tailored advice, and access to self-help EMH interventions. The effects on work functioning, stress, and work-related fatigue after 3 months were analyzed using paired t tests and effect sizes. One hundred and twenty-eight nurses and allied health professionals participated at pretest as well as posttest. Significant improvements were found on work functioning (p = 0.01) and work-related fatigue (p Work functioning had relevantly improved in 30% of participants. A small meaningful effect on stress was found (Cohen d = .23) in the participants who had logged onto an EMH intervention (20%, n = 26). The EMH approach to WHS improves the work functioning and mental health of nurses and allied health professionals. However, because we found small effects and participation in the offered EMH interventions was low, there is ample room for improvement.

    This study aimed to investigate the improvement to pre-service teacher’s communication skills through Higher Order Thinking Laboratory (HOT Lab) on electric circuit topic. This research used the quasi-experiment method with pretest-posttest control group design. Research subjects were 60 students of Physics Education in UIN Sunan Gunung Djati Bandung. The sample was chosen by random sampling technique. Students’ communication skill data collected using a communication skills test instruments-essays form and observations sheets. The results showed that pre-service teacher communication skills using HOT Lab were higher than verification lab. Student’s communication skills in groups using HOT Lab were not influenced by gender. Communication skills could increase due to HOT Lab based on problems solving that can develop communication through hands-on activities. Therefore, the conclusion of this research shows the application of HOT Lab is more effective than the verification lab to improve communication skills of pre-service teachers in electric circuit topic and gender is not related to a person’s communication skills.

    Emotional functioning plays a crucial role in the social development of children and adolescents. We examined the extent to which emotion control was related to the quality of friendships in pre-adolescents with and without hearing loss. We tested 350 pre-adolescents (75 deaf/hard of hearing in mainstream education (DHHm), 48 deaf/hard of hearing in special education (DHHs), and 227 hearing) through self-report. Outcomes confirmed a positive association between emotion control and positive friendships for all groups, with one notable exception: more approach strategies for emotion regulation were associated with more negative friendship features in the DHHs group. In addition, the DHHm group demonstrated high levels of emotion control, while their levels of positive friendship features were still lower compared to the hearing group.

    Full Text Available Learning a foreign language is a challenging process in which learners need motivation and encouragement through the use of modern techniques. The present paper investigates the effects digital stories may have on Iranian pre-intermediate EFL learners’ listening comprehension. To this end, the researchers carried out a quasi-experimental research in a language institution in Tabriz (Iran. In total, forty, 11-14-year-old female students participated in this research. Twenty students were in the experimental group and twenty in the control group. The Preliminary English Test (PET was administered at the beginning of the study to check whether all participants were homogeneous in terms of English language proficiency. A pre-test of listening comprehension was designed to gather initial data on the learners' listening skill prior to the treatment. The experimental group was presented with digital stories in a technology-equipped classroom. After the treatment, a post-test was administered to both groups to test the learners' progression in listening comprehension. Then, using an ANCOVA test, the performance of two groups was compared.The findings indicated that the experimental group outperformed the control group in the final test. The results raise interesting issues related to the use of technology in the context of foreign language learning, substantiating the link between technology rich environment and improved language learning.

    This paper presents the pre- and post-test results of the outcomes of a workshop designed to increase learning disability and mental health nurses' knowledge and skill to undertake interventions for service users at risk of, or with a diagnosis of, type 2 diabetes. Health literacy is also discussed as a way of explaining why such nurses may lack expertise in physical health care. Findings from the workshop show that learning disability and mental health nurses have the motivation to increase their health literacy (skills and knowledge) in diabetes care. The potential of such workshops, and how organisations looking forward to the future can build health literacy, is discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2013-03-01

    In this pilot project, one hour of lecture time was replaced with one hour of in-class assignments, which groups of students collaborated on. These in-class assignments consisted of problems or projects selected for the calculus-based introductory physics students The first problem was at a level of difficulty that the majority of the students could complete with a small to moderate amount of difficulty. Each successive problem was increasingly more difficult, the last problem being having a level of difficulty that was beyond the capabilities of the majority of the students and required some instructor intervention. The students were free to choose their own groups. Students were encouraged to interact and help each other understand. The success of the in-class exercises were measured using pre-tests and post-tests. The pre-test and post-test were completed by each student independently. Statistics were also compiled on each student's attendance record and the amount of time spent reading and studying, as reported by the student. Statistics were also completed on the student responses when asked if they had sufficient time to complete the pre-test and post-test and if they would have completed the test with the correct answers if they had more time. The pre-tests and post-tests were not used in the computation of the grades of the students.

    The aim of the research was to examine whether a role-focused self-help course intervention would decrease caregiver stress and distress, and functioning problems, among people who suffer stress because they combine paid work with informal care. A pre-registered (NTR 5528) randomized controlled design was applied (intervention vs. wait list control). Participants (n = 128) were people who had paid work and were suffering stress due to their involvement in informal care activities. Participants allocated to the intervention group (n = 65) received the role-focused self-help course. Control group members (n = 63) received this intervention after all measurements. Prior to the random allocation (pre-test), and 1 month (post-test 1) and 2 months (post-test 2) after allocation, all participants completed a questionnaire that measured their caregiver stress (primary outcome), distress, work functioning, negative care-to-work interference and negative care-to-social and personal life interference. Mixed model ANOVAs were used to test the effectiveness of the intervention. Two months after allocation, the intervention group participants had lower levels of caregiver stress and distress compared with the control group participants. The intervention did not directly resolve impaired work functioning or interference of care with work and social/personal life. The intervention decreases caregiver stress and distress in people who suffer stress because they combine paid work with informal caring.

    Full Text Available Teachers’ beliefs about family-school relationship vary in a continuum according to the role that parents and teachers have, and the power that they hold. Pre-service teachers also have beliefs about this relationship and their own competence to develop it. Two groups of pre-service teachers (second year students participated in this study. One group received specific training on family-school relationship and its improvement (116 students attending a degree in Early Childhood Education, who constituted the experimental group, EG. The other group was not trained (92 students attending a degree in Primary Education, who made up the control group, CG. The Beliefs about family-school Questionnaire (CCR was developed and applied before and after the EG was trained. Results show that students in the EG increased their beliefs about family-school collaboration in the post-test and decreased their beliefs about parental subordination to teachers’ authority and parents’ carelessness. Students in the CG kept their beliefs unchanged, which were significantly more prone to support teachers’ authority and parental subordination and parents’ carelessness compared to the EG.. Perceived competence for family-school relationship did not change significantly in either group. However, significant correlations between beliefs and perceived competence were found, pointing out the importance of working pre-service teachers’ beliefs about family-school collaboration.

    The aim of the study was to determine the effects of a simulated communication training course on nurses' communication competence, self-efficacy, communication performance, myocardial infarction knowledge, and general satisfaction with their learning experience. A randomized controlled trial was conducted with a pre-test and two post-tests. The experimental group underwent simulated communication training course and the control group received a case-based communication training course. The experimental group made more significant improvement in competence and self-efficacy in communication from pre-test to the second post-test than the control group. Although both groups' satisfaction with their learning experience significantly increased from the first post-test to the second post-test, the experimental group was found to be more satisfied with their learning experience than the control group. No significant differences in communication performance and myocardial infarction knowledge between the two groups were identified. Scenario-based communication training can be more fully incorporated into in-service education for nurses to boost their competence and self-efficacy in communication and enhance their communication performance in myocardial infarction patient care. Introduction of real-life communication scenarios through multimedia in communication education could make learners more motivated to practice communication, hence leading to improved communication capacity.

    Breast cancer is a malignant disease, which lead to second cause of that after cervical cancer in women. To date, lots of drugs and supplement have been developed and consumed by patients. Shark bone is one of the supplements that might inhibit the proliferation of cancer cells. The application of shark bone powder for supplementation in breast cancer cases still becomes controversy; but until now people are still many who consume as a supplement. This study aimed to prove the potency of shark bone powder in the inhibition of breast cancer proliferation and to propose the possibility of its biological mechanism. The pre-clinical experimental study used a controlled posttest controlled design with 25 white rats strains of DML-induced Sprague-Dawley strains. The cancer markers observed were p53, AgNORs, VEGF, Bcl-2, and Cas-3. The test subjects were divided into 3 groups: control group and 2 treatment groups fed modified with 60% and 90% respectively. A pre-clinical trial of shark bone powder showed that there was significant inhibition for the DMBA-induced anti proliferation and breast cell cancer (p breast cancer proliferation lies in concentration 30mg/BB/day.

    This study evaluated a positive parenting program to Brazilian mothers who used corporal punishment with their children. The intervention was conducted in four agencies serving vulnerable children, and at a home replica laboratory at the University. Mothers who admitted using corporal punishment were randomly assigned between experimental (n=20) and control group (n=20). The program consisted of 12 individual sessions using one unit from Projeto Parceria (Partnership Project), with specific guidelines and materials on positive parenting, followed by observational sessions of mother-child interaction with live coaching and a video feedback session in the lab. The study used an equivalent group experimental design with pre/post-test and follow-up, in randomized controlled trials. Measures involved: Initial Interview; Strengths and Difficulties Questionnaire (SDQ) - parent and child versions; Beck Depression Inventory (BDI); observational sessions with a protocol; and a Program Evaluation by participants. Analysis of mixed models for repeated measures revealed significant positive effects on the BDI and SDQ total scores, as well as less Conduct problems and Hyperactivity in SDQ measures from the experimental group mothers, comparing pre with post-test. Observational data also indicated significant improvement in positive interaction from the experimental group mothers at post-test, in comparison with controls. No significant results were found, however, in children's observational measures. Limitations of the study involved using a restricted sample, among others.

  17. Is it the intervention or the students? using linear regression to control for student characteristics in undergraduate STEM education research.

    Science.gov (United States)

    Theobald, Roddy; Freeman, Scott

    2014-01-01

    Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention or to differences in student characteristics when students cannot be assigned to control and treatment groups at random. Using pre- and posttest scores from an introductory biology course, we illustrate how the methods currently in wide use can lead to erroneous conclusions, and how multiple linear regression offers an effective framework for distinguishing the impact of an instructional intervention from the impact of student characteristics on test score gains. In general, we recommend that researchers always use student-level regression models that control for possible differences in student ability and preparation to estimate the effect of any nonrandomized instructional intervention on student performance.

    Full Text Available : This study aimed to investigate the effectiveness of group cognitive-behavioral therapy on aggression among addicts. Method: A quasi-experimental design along with pre-posttest stages, control group, and follow-up was employed for the conduct of this study. The number of 24 addicts referring to rehabilitation clinics in Tehran was selected as the sample size of this study via convenience sampling method in accordance with the inclusion criteria. These participants were randomly assigned to experimental and control groups. In this study, Buss-Perry Aggression Questionnaire was used for data collection purposes. Results: Data analysis showed that group cognitive-behavioral therapy reduces verbal and physical aggression, anger, and hostility in addicted people. However, this therapy only led to the reduction of verbal aggression, anger, and hostility in addicted people. Conclusion: Since aggression has a high comorbidity with substance abuse, this factor can be as an obstacle to withdrawal. Therefore, it must be considered in addiction treatment.

    Method: The study used a cluster randomised control trial design. The study included 211 Grade 7 participants from schools in the Cape Town Metropole. The CCR intervention was administered to 97 participants in the experimental group, whilst 114 participants in the control group did not receive the intervention. The Stuttering Resource Outcome Measure(SROM used as the outcome measure during pre- and post-test period. STATISTICA was used for in-depth data analysis. Results: An overall positive direction of change in scores was observed for the experimental group compared with the control group. However, the magnitude of change in the experimental group was not statistically significant (p = 0.2683. Male and female participants did not differ significantly in their scores on the SROM across pre-test and post-test periods. Participants who had exposure to individuals who stutter had significantly more positive scores on the SROM in the pre-test and post-test periods compared to those who had no direct exposure to stuttering. Conclusion: This result indicated the beginning of positive attitude change which may be attributed to the intervention. Further investigation is warranted.

The PANDA test P4 has provided data about how trapped air released from the drywell later in the transient affects PCCS performance in an adequate manner. The well-defined measurements can serve as an important database for the assessment of thermal hydraulic system analysis codes, especially for conditions that could be met in passively operated advanced reactors, i.e. low pressure and small driving forces. Based on the analysis of the test data, the test acceptance criteria have been met. The test P4 has been successfully completed and the instrument readings were with the permitted ranges. The PCCs showed a favorable and robust performance and a wide margin for decay heat removal from the containment. The PANDA P4 test demonstrated that trapped air, released from the drywell later in the transient, only temporarily and only slightly affected the performance of the passive containment cooling system. The analysis of the results of the RELAPS code showed that the overall behaviour of the test has been calculated quite well with regards to pressure, mass flow rates, and pool boil-down. This accounts both for the pre-test and the post-test simulations. However, due to the one-dimensional, stacked-volume modeling of the PANDA DW, WW, and GDCS vessels, 3D-effects such as in-vessel mixing and recirculation could not be calculated. The post-test MELCOR simulation showed an overall behaviour that is comparable to RELAPS. However, MELCOR calculated almost no air trapping in the PCC tubes that could hinder the steam condensation rate. This resulted in lower calculated

    This randomized controlled parallel trial investigates the effect of 3D animation on the increase and recall of knowledge on periodontitis by patients with periodontitis. The effects of a 3D animation (3D animation group) were compared with narration and drawing (control group) for periodontal patient education. A total of 68 periodontitis patients were stratified according to educational level and then randomly allocated to control or 3D animation groups. All patients received: (1) a pre-test (baseline knowledge), (2) a patient education video (3D animation or control video), (3) a post-test (knowledge immediately after looking at the video), and (4) a follow-up test (knowledge recall after 2 weeks). Each test contained 10 multiple-choice questions. There was no significant difference in baseline knowledge. Patients receiving the 3D animations had significantly higher scores for both the post-test and the follow-up test, when compared with patients receiving sketch animations. 3D animations are more effective than real-time drawings for periodontal patient education in terms of knowledge recall. 3D animations may be a powerful tool for assisting in the information process. © 2013 John Wiley & Sons A/S.

    We hypothesized that Theory of Planned Behavior (TPB) constructs (behavioral belief, attitude, subjective norm, perceived behavioral control, knowledge and behavioral intention) regarding preventive behaviors for obesity and type 2 diabetes will change favorably after completing the web-based intervention, HOT (Healthy Outcome for Teens) project, grounded in the TPB; and that passive online learning (POL) group will improve more than the active online learning (AOL) group. The secondary hypothesis was to determine to what extent constructs of the TPB predict intentions. 216 adolescents were recruited, 127 randomly allocated to the treatment group (AOL) and 89 to the control group (POL). The subjects completed a TPB questionnaire pre and post intervention. Both POL and AOL groups showed significant improvements from pretest to posttest survey. However, the results indicated no significant difference between POL and AOL for all constructs except behavioral belief. Correlational analysis indicated that all TPB constructs were significantly correlated with intentions for pretest and posttest for both groups. Attitude and behavioral control showed strongest correlations. Regression analysis indicated that TPB constructs were predictive of intentions and the predictive power improved post intervention. Behavioral control consistently predicted intentions for all categories and was the strongest predictor for pretest scores. For posttest scores, knowledge and attitude were the strongest predictors for POL and AOL groups respectively. Thus, HOT project improved knowledge and the TPB constructs scores for targeted behaviors, healthy eating and physical activity, for prevention of obesity and type 2 diabetes.

    Graduate medical students often get less opportunity for clarifying their doubts and to reinforce their concepts after lecture classes. The Medical Council of India (MCI) encourages group discussions among students. We evaluated the effect of identifying mistakes in a given set of wrong statements and their correction by a small group discussion by graduate medical students as a revision exercise. At the end of a module, a pre-test consisting of multiple-choice questions (MCQs) was conducted. Later, a set of incorrect statements related to the topic was given to the students and they were asked to identify the mistakes and correct them in a small group discussion. The effects on low, medium and high achievers were evaluated by a post-test and delayed post-tests with the same set of MCQs. The mean post-test marks were significantly higher among all the three groups compared to the pre-test marks. The gain from the small group discussion was equal among low, medium and high achievers. The gain from the exercise was retained among low, medium and high achievers after 15 days. Identification of mistakes in statements and their correction by a small group discussion is an effective, but unconventional revision exercise in biochemistry. Copyright 2014, NMJI.

    The purpose of this research was to determine if there were differences in academic performance between students who participated in traditional versus collaborative problem-based learning (PBL) instructional design approaches to physics curricula. This study utilized a quantitative quasi-experimental design methodology to determine the significance of differences in pre- and posttest introductory physics exam performance between students who participated in traditional (i.e., control group) versus collaborative problem solving (PBL) instructional design (i.e., experimental group) approaches to physics curricula over a college semester in 2008. There were 42 student participants (N = 42) enrolled in an introductory physics course at the research site in the Spring 2008 semester who agreed to participate in this study after reading and signing informed consent documents. A total of 22 participants were assigned to the experimental group (n = 22) who participated in a PBL based teaching methodology along with traditional lecture methods. The other 20 students were assigned to the control group (n = 20) who participated in the traditional lecture teaching methodology. Both the courses were taught by experienced professors who have qualifications at the doctoral level. The results indicated statistically significant differences (p traditional (i.e., lower physics posttest scores and lower differences between pre- and posttest scores) versus collaborative (i.e., higher physics posttest scores, and higher differences between pre- and posttest scores) instructional design approaches to physics curricula. Despite some slight differences in control group and experimental group demographic characteristics (gender, ethnicity, and age) there were statistically significant (p = .04) differences between female average academic improvement which was much higher than male average academic improvement (˜63%) in the control group which may indicate that traditional teaching methods

    This study examined the effects of GeoGebra on mathematics performance of students with different spatial visualization. A qusai-experimental, pretest-posttest control group design was conducted. A total of 71 students from two intact groups were involved in the study. They were in two groups and each group was randonly assigned to the experimental group (36 students) and control group (35 students). A spatial visual test to identify students with high or low visualization, and a mathematics performance pre-test were administered at the initial stage of this study. A post-test was administered after 12 weeks of treatment using GeoGebra. Analyses of Covarion (ANCOVA) was used to adjust for the pre-test score. Findings showed that the group with access to GeoGebra achieved significantly better test scores in the posttest as compared to the group which followed the traditional teaching method. A two-way ANCOVA used to analyse the effect of students' spatial visualization on post-test performance showed that there was no effect. The results from this study suggested that using GeoGebra had helped the students to score better in the posttest. However, there is no significance difference on mathematics performances on students with difference types of spatial visualisastion. This study indicates that GeoGebra is useful in enhancing the teaching and learning of mathematics.

    In-service education affects the quality of cancer care directly. Using classroom teaching to deliver in-service education is often ineffective due to participants' large workload and shift requirements. This study evaluated the learning effectiveness of different teaching methods in the dimensions of knowledge, attitude, and learning satisfaction. This study used a quasi-experimental study design. Participants were cancer ward nurses working at one medical center in northern Taiwan. Participants were divided into an experimental group and control group. The experimental group took an e-learning course and the control group took a standard classroom course using the same basic course material. Researchers evaluated the learning efficacy of each group using a questionnaire based on the quality of cancer nursing care learning effectiveness scale. All participants answered the questionnaire once before and once after completing the course. (1) Post-test "knowledge" scores for both groups were significantly higher than pre-test scores for both groups. Post-test "attitude" scores were significantly higher for the control group, while the experimental group reported no significant change. (2) after a covariance analysis of the pre-test scores for both groups, the post-test score for the experimental group was significantly lower than the control group in the knowledge dimension. Post-test scores did not differ significantly from pre-test scores for either group in the attitude dimension. (3) Post-test satisfaction scores between the two groups did not differ significantly with regard to teaching methods. The e-learning method, however, was demonstrated as more flexible than the classroom teaching method. Study results demonstrate the importance of employing a variety of teaching methods to instruct clinical nursing staff. We suggest that both classroom teaching and e-learning instruction methods be used to enhance the quality of cancer nursing care education programs. We

    2014-01-01

    In a prior study (Stein et al., 2013), we reported that rats pre-exposed to delayed rewards made fewer impulsive choices, but consumed more alcohol (12% wt/vol), than rats pre-exposed to immediate rewards. To understand the mechanisms that produced these findings, we again pre-exposed rats to either delayed (17.5 s; n = 32) or immediate (n = 30) rewards. In post-tests, delay-exposed rats made significantly fewer impulsive choices at both 15- and 30-s delays to a larger, later food reward than the immediacy-exposed comparison group. Behavior in an open-field test provided little evidence of differential stress exposure between groups. Further, consumption of either 12% alcohol or isocaloric sucrose in subsequent tests did not differ between groups. Because Stein et al. introduced alcohol concentration gradually (3–12%), we speculate that their group differences in 12% alcohol consumption were not determined by alcohol’s pharmacological effects, but by another variable (e.g., taste) that was preserved as an artifact from lower concentrations. We conclude that pre-exposure to delayed rewards generalizes beyond the pre-exposure delay; however, this same experimental variable does not robustly influence alcohol consumption. PMID:25418607

    While a number of instructional models focus on the use of analogies, research into their effectiveness in enhancing comprehension and retention of scientific concepts, particularly involving adult learners, has been limited. The purpose of this study was to determine the efficacy of using the common teaching strategy for comparing the function of a coral reef to that of a city by using an analogy-based instructional model termed FAR. The training program entitled "Marine Resource Management for Dive Professionals" (MRMDP) was developed for this study. It was targeted to professionals in the recreational scuba industry to improve their understanding of coal reef ecology, as well as orient them to pertinent marine resource management issues, and promote environmentally-responsible attitudes and diving practices among their clients. A quasi-experimental pre-post-delayed posttest control group design was used to explore five research questions and corresponding hypotheses. A 55-item researcher-developed test of coral reef ecology was administered pre and post instruction. The delayed posttest was self-administered by the subjects three weeks after course completion. Data on seven experiential variables hypothesized as research factors were collected. Ten MRMPD courses were taught in seven nations, involving 194 subjects (85 subjects in four control courses, 109 in six treatment course). The results were analyzed using multiple regression/correlation (MRC) techniques to determine: (1) any significant relationship between pretest performance and experiential variables, (2) treatment versus control group posttest performance, and (3) treatment versus control group delayed posttest performance. Within the treatment group, learning gains and retention were determined by t-test analysis. Results indicated: (1) all research factors except one were significant predictors of pretest scores in the presence of the covariate; (2) no significant difference was found between

    Double blind pre-test post-test control group design. To compare the isokinetic quadriceps torque, standardized stair-climbing task (SSCT) and pain during SSCT between subjects diagnosed with knee osteoarthritis pre and post kinesio tape (KT) application with and without tension. Strength of the quadriceps and torque producing capability is frequently found to be compromised in knee osteoarthritis. The efficacy of KT in improving isokinetic quadriceps torque in knee osteoarthritis is unknown, forming the basis for this study. Forty subjects were randomly allocated to either the experimental (therapeutic KT with tension) or control group (sham KT without tension) with the allocation being concealed. Pre and post test measurements of isokinetic quadriceps torque, SSCT and pain during SSCT were carried out by a blinded assessor. A large effect size with significant improvements in the peak quadriceps torque (concentric and eccentric at angular velocities of 90° per second and 120° per second), SSCT and pain were obtained in the experimental group when compared to the control group. Application of therapeutic KT is effective in improving isokinetic quadriceps torque, SSCT and reducing pain in knee osteoarthritis.

    Full Text Available When lay jurors are unfamiliar with key evidentiary issues, expert evidence, judicial instructions and group deliberation may enhance their understanding of this evidence. Systematic steps to assess the relationship between juror biases in cases of child sexual abuse are offered as an example to illustrate a programmatic research approach. Using pretest-posttest research designs, the effectiveness of three traditional legal procedural safeguards to reduce common jury misconceptions in the context of simulated trials were tested and compared. By measuring mock-juror knowledge before and after each intervention, knowledge gains attributable to these interventions were distinguished from practice effects. Unexpected increases in acquittals following deliberation underscored the importance of adding adequate control groups and of testing deliberation effects in jury simulation studies. Benefits of this research paradigm to assist courts, legal counsel and policy makers in devising effective methods to enhance jury decisions in complex criminal cases are discussed. Cuando los miembros del jurado popular no están familiarizados con los temas probatorios clave, las pruebas periciales, las instrucciones judiciales y la deliberación de grupo pueden mejorar su comprensión de las evidencias.

    Currently, many undergraduate nursing courses use blended-learning course formats with success; however, little evidence exists that supports the use of blended formats in introductory pathophysiology courses. The purpose of this study was to compare the scores on pre- and posttests and course satisfaction between traditional and blended course formats in an introductory nursing pathophysiology course. This study used a quantitative, quasi-experimental, nonrandomized control group, pretest-posttest design. Analysis of covariance compared pre- and posttest scores, and a t test for independent samples compared students' reported course satisfaction of the traditional and blended course formats. Results indicated that the differences in posttest scores were not statistically significant between groups. Students in the traditional group reported statistically significantly higher satisfaction ratings than students in the blended group. The results of this study support the need for further research of using blended learning in introductory pathophysiology courses in undergraduate baccalaureate nursing programs. Further investigation into how satisfaction is affected by course formats is needed. Copyright 2016, SLACK Incorporated.

    To test feasibility of a guided audio-visual relaxation intervention protocol for reducing stress and pain in adults with sickle cell disease. Sickle cell pain is inadequately controlled using opioids, necessitating further intervention such as guided relaxation to reduce stress and pain. Attention-control, randomized clinical feasibility pilot study with repeated measures. Randomized to guided relaxation or control groups, all patients recruited between 2013-2014 during clinical visits, completed stress and pain measures via a Galaxy Internet-enabled Android tablet at the Baseline visit (pre/post intervention), 2-week posttest visit and also daily at home between the two visits. Experimental group patients were asked to use a guided relaxation intervention at the Baseline visit and at least once daily for 2 weeks. Control group patients engaged in a recorded sickle cell discussion at the Baseline visit. Data were analysed using linear regression with bootstrapping. At baseline, 27/28 of consented patients completed the study protocol. Group comparison showed that guided relaxation significantly reduced current stress and pain. At the 2-week posttest, 24/27 of patients completed the study, all of whom reported liking the study. Patients completed tablet-based measures on 71% of study days (69% in control group, 72% in experiment group). At the 2-week posttest, the experimental group had significantly lower composite pain index scores, but the two groups did not differ significantly on stress intensity. This study protocol appears feasible. The tablet-based guided relaxation intervention shows promise for reducing sickle cell pain and warrants a larger efficacy trial.

    Research about the effect of Peer Assisted Learning (PAL) strategy on Plant Anatomy Course, which aims to improve anatomic competencies of prospective student’s biology teacher, has been done. This study used a quasi-experimental pre-test post-test control group design. The draft includes a group of students who were given a pre-test which is then followed by observing the PAL treatment process and post-test. The other students group (control) was given the pre-test and post-test only. The PAL program began with a discussion between the lecturer and the tutor about the pretest results and then discussion between the tutors and their tutees in the class about the responses items. After that, all students were assigned to answer a set of response items, and then did the posttest. The results showed that the PAL strategy can increase student’s anatomic literacy significantly and can increase student’s anatomic lab skills no significantly. Thus the PAL strategy implementation has a potential to improve student’s anatomic competencies. The generally students weaknesses were they lack practice in interpreting of research results in the graphs form and rarely shared about anatomic lab skills. All students respond positively to the PAL strategy.

    Virtual microscopy is being introduced in medical education as an approach for learning how to interpret information in microscopic specimens. It is, however, far from evident how to incorporate its use into existing teaching practice. The aim of the study was to explore the consequences of introducing virtual microscopy tasks into an undergraduate pathology course in an attempt to render the instruction more process-oriented. The research questions were: 1) How is virtual microscopy perceived by students? 2) Does work on virtual microscopy tasks contribute to improvement in performance in microscopic pathology in comparison with attending assistant-led demonstrations only? During a one-week period, an experimental group completed three sets of virtual microscopy homework assignments in addition to attending demonstrations. A control group attended the demonstrations only. Performance in microscopic pathology was measured by a pre-test and a post-test. Student perceptions of regular instruction and virtual microscopy were collected one month later by administering the Inventory of Intrinsic Motivation and open-ended questions. The students voiced an appreciation for virtual microscopy for the purposes of the course and for self-study. As for learning gains, the results indicated that learning was speeded up in a subgroup of students consisting of conscientious high achievers. The enriched instruction model may be suited as such for elective courses following the basic course. However, the instructional model needs further development to be suited for basic courses.

    Full Text Available Abstract Background Team-based learning (TBL, a new active learning method, has not been reported for neurology education. We aimed to determine if TBL was more effective than passive learning (PL in improving knowledge outcomes in two key neurology topics - neurological localization and neurological emergencies. Methods We conducted a modified crossover study during a nine-week internal medicine posting involving 49 third-year medical undergraduates, using TBL as the active intervention, compared against self-reading as a PL control, for teaching the two topics. Primary outcome was the mean percentage change in test scores immediately after (post-test 1 and 48 hours after TBL (post-test 2, compared to a baseline pre-test. Student engagement was the secondary outcome. Results Mean percentage change in scores was greater in the TBL versus the PL group in post-test 1 (8.8% vs 4.3%, p = 0.023 and post-test 2 (11.4% vs 3.4%, p = 0.001. After adjustment for gender and second year examination grades, mean percentage change in scores remained greater in the TBL versus the PL group for post-test 1 (10.3% vs 5.8%, mean difference 4.5%,95% CI 0.7 - 8.3%, p = 0.021 and post-test 2 (13.0% vs 4.9%, mean difference 8.1%,95% CI 3.7 - 12.5%, p = 0.001, indicating further score improvement 48 hours post-TBL. Academically weaker students, identified by poorer examination grades, showed a greater increase in scores with TBL versus strong students (p Conclusions Compared to PL, TBL showed greater improvement in knowledge scores, with continued improvement up to 48 hours later. This effect is larger in academically weaker students. TBL is an effective method for improving knowledge in neurological localization and neurological emergencies in undergraduates.

    This study entailed a 3 (instructional intervention) × 2 (assessment-type) between-subjects experimental design employing a pretest-intervention-posttest methodology. The instructional interventions were administered between subjects in three conditions: (a) dynamic instruction, (b) triarchic or theory of successful intelligence-control instruction, and (c) standard-control instruction. The assessment-type consisted between subjects of either (a) a group-administered dynamic posttest or (b) the same group-administered posttest interspersed with a control filler activity. Performance in different mathematics content areas taught in fourth grade was investigated. In total, 1,332 students and 63 classroom teachers in 24 schools across six school districts participated in the study. The results indicate the advantages of using dynamic instruction and assessment in regular classrooms while teaching mathematics, especially when the student body is highly ethnically diverse.

    This study compared the effects of reading-oriented tasks and writing-oriented tasks on students' reading comprehension of geometry proof (RCGP). The reading-oriented tasks were designed with reading strategies and the idea of problem posing. The writing-oriented tasks were consistent with usual proof instruction for writing a proof and applying it. Twenty-two classes of ninth-grade students ( N = 683), aged 14 to 15 years, and 12 mathematics teachers participated in this quasi-experimental classroom study. While the experimental group was instructed to read and discuss the reading tasks in two 45-minute lessons, the control group was instructed to prove and apply the same propositions. Generalised estimating equation (GEE) method was used to compare the scores of the post-test and the delayed post-test with the pre-test scores as covariates. Results showed that the total scores of the delayed post-test of the experimental group were significantly higher than those of the control group. Furthermore, the scores of the experimental group on all facets of reading comprehension except the application facet were significantly higher than those of the control group for both the post-test and delayed post-test.

    Full Text Available The aim of this study was to find out whether listening to English songs can improve pre-intermediate EFL learners’ listening comprehension. To this end, a non-randomized pretest-posttest control group design as one of the quasi-experimental research designs was employed. The sample of the study consisted of 40 male and female English learners from two classes in an Institute in Marand, Iran. The two classes were randomly assigned into the experimental and control groups.  Then, a PET test was used to check the homogeneity of both groups. The listening section of PET was also considered as the pretest of the study. Then, fifteen English songs were used in the experimental group during the treatment period. Each session, within 45 minutes, one song was played for and practiced with the learners. Meanwhile, the control group had their usual teacher -fronted class without listening to songs. At the end, both groups were post tested on their listening comprehension using the listening section of another version of PET. The collected data were analyzed using Independent-Samples and Paired-Samples t-tests. The results revealed a statistically significant improvement in the performance of the experimental group. It is implied that songs are not only an entertaining tool but they can also be used as a pedagogic material in improving learners’ listening comprehension.

    Decision making is impaired in hypoxic environments, which may have serious or even lethal consequences for mountaineers. An acclimatisation period prior to high altitude exposures may help to overcome adverse effects of hypoxia. Thus, we investigated possible effects of short-term pre-acclimatisation on decision making in hypoxia. In a randomized controlled study design, 52 healthy participants were allocated to a hypoxia group (HG: short-term pre-acclimatisation by the use of intermittent hypoxia 7×1h at F i O 2 =12.6%, equivalent to 4500m) or a control group (CG: sham pre-acclimatisation 7×1h at F i O 2 =20.9%, equivalent to 600m). The number of risky decisions was assessed using the Game of Dice Task at four time points during a 12-hours stay in hypoxia (F i O 2 =12.6%). 42 (HG: 27, CG: 25) participants completed the study. The number of risky decisions was significantly (p=0.048 as determined by 4×2 ANCOVA) reduced in the hypoxia group compared to the control group, partial η 2 =0.11, when the age-effect on decision making was controlled. Self-reported positive affective valence prior to decision making was negatively related to the number of risky decisions, rdecision making in hypoxia in a positive way and might be considered as a risk-reducing preparation method prior to exposures to hypoxic environments. Positive affective states seem to have a medium-sized protective effect against risky decision making. Copyright © 2017 Elsevier Inc. All rights reserved.

    The goal of this pilot study was to ascertain the effectiveness of an occupation-based after-school program for improving self-concept in children, ages five through eight. Fifty-four randomly selected children ages five through eight from two schools (one being the control group) with similar socioeconomic status along the Ohio River were involved in this research study. The Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PCSA; Harter & Pike, 1984) was administered to all participants (N = 54), four subtests were analyzed: cognitive competence, social competence with peers, physical competence in sports, and maternal acceptance. The experimental group (n = 25) attended occupation-based groups two times a week after school. The control group (n = 29) did not participate in an after-school program. Data from pre-test and post-test were analyzed using a t-test. Findings demonstrated that the experimental group improved their self-concept scores when compared to the control group in the areas of peer acceptance and cognitive competence. This would offer tentative evidence that an after-school program directed by occupational therapists that is designed to improve self-concept may be successful.

    The purpose of the present study was to determine the effect of composition (art or music) on the self-concept of hospitalized children. The music composition was created using the program Making More Music. The art composition was a drawing using standard medium. The Piers-Harris Children's Self-Concept Scale was used to measure self-concept. When examining subjects as one group, a significant difference from pre- to posttest for the Total score indicated an improved self-concept. Further analyses on each of the 6 categories indicated no significant differences. The art composition group had a significant difference from pre- to posttest for the Total score and for Popularity (POP). Although not significant, scores increased from pre- to posttest for Behavioral Adjustment (BEH), Physical Appearance (PHY), Freedom from Anxiety (FRE), and Happiness and Satisfaction (HAP). The music composition group had no significant difference from pre- to posttest for the Total score but a significant difference from pre- to posttest on Intellectual and School Status (INT) and Physical Appearance (PRY). Although not significant, scores increased from pre- to posttest for TOT, BEH, and HAP. There was a significant difference between the groups on 2 categories that indicated an improved self-concept for the music group under Intellectual and School Status and for the art group under Popularity.

    For a successful design and analysis of Sodium cooled Fast Reactor (SFR), it is required to have a reliable and well-proven system analysis code. To achieve this purpose, KAERI is enhancing the modeling capability of MARS code by adding the SFR-specific models such as pressure drop model, heat transfer model and reactivity feedback model. This version of MARS-LMR will be used as a basic tool in the design and analysis of future SFR systems in Korea. Before wide application of MARS-LMR code, it is required to verify and validate the code models through analyses for appropriate experimental data or analytical results. The end-of-life test of Phenix reactor performed by the CEA provided a unique opportunity to have reliable test data which is very valuable in the validation and verification of a SFR system analysis code. The KAERI joined this international program of the analysis of Phenix end-of-life natural circulation test coordinated by the IAEA from 2008. The main test of natural circulation was completed in 2009. Before the test the KAERI performed the pre-test analysis based on the design condition provided by the CEA. Then, the blind post-test analysis was also performed based on the test conditions measured during the test before the CEA provide the final test results. Finally, the final post-test analysis was performed recently to predict the test results as accurate as possible. This paper introduces the modeling approach of the MARS-LMR used in the final post-test analysis and summarizes the major results of the analysis

    Sala, Giovanni; Gobet, Fernand

    2017-12-01

    It has been proposed that playing chess enables children to improve their ability in mathematics. These claims have been recently evaluated in a meta-analysis (Sala & Gobet, 2016, Educational Research Review, 18, 46-57), which indicated a significant effect in favor of the groups playing chess. However, the meta-analysis also showed that most of the reviewed studies used a poor experimental design (in particular, they lacked an active control group). We ran two experiments that used a three-group design including both an active and a passive control group, with a focus on mathematical ability. In the first experiment (N = 233), a group of third and fourth graders was taught chess for 25 hours and tested on mathematical problem-solving tasks. Participants also filled in a questionnaire assessing their meta-cognitive ability for mathematics problems. The group playing chess was compared to an active control group (playing checkers) and a passive control group. The three groups showed no statistically significant difference in mathematical problem-solving or metacognitive abilities in the posttest. The second experiment (N = 52) broadly used the same design, but the Oriental game of Go replaced checkers in the active control group. While the chess-treated group and the passive control group slightly outperformed the active control group with mathematical problem solving, the differences were not statistically significant. No differences were found with respect to metacognitive ability. These results suggest that the effects (if any) of chess instruction, when rigorously tested, are modest and that such interventions should not replace the traditional curriculum in mathematics.

    Individuals with developmental disabilities may engage in automatically reinforced behaviors that may interfere with learning opportunities. Manipulation of motivating operations has been shown to reduce automatically maintained behavior in some individuals. Considering behavioral indicators of satiation may assist in identifying the point at which an abolishing operation has begun to effect behavior. The purpose of this study was to evaluate the effects of pre-session satiation of automatic reinforcement on subsequent levels of stereotypy and activity engagement during group activities for three males ages 5 to 13 years with developmental disabilities. Following functional analyses with analogue conditions, an alternating treatment design compared a pre-session access to stereotypy condition with a no-pre-session access condition prior to group activity sessions. Results indicated that pre-session satiation of the putative reinforcer produced by stereotypy was effective in decreasing stereotypy and increasing activity engagement during subsequent group activities for all participants. These findings add to the literature supporting the effectiveness of abolishing operations to decrease automatically maintained stereotypy. © The Author(s) 2013.

    The aim of our study was to determine if a fresh cadaver model is a viable method for teaching ultrasound (US)-guided breast biopsy of palpable breast lesions. Third-year medical students were assessed both preinstruction and postinstruction on their ability to perform US-guided needle aspiration or biopsy of artificially created masses using a 10-item checklist. Forty-one third-year medical students completed the cadaver laboratory as part of the surgery clerkship. Eight items on the checklist were found to be significantly different between pre-testing and post-testing. The mean preinstruction score was 2.4, whereas the mean postinstruction score was 7.10 (P cadaver models have been widely used in medical education. However, there are few fresh cadaver models that provide instruction on procedures done in the outpatient setting. Our model was found to be an effective method for the instruction of US-guided breast biopsy among medical students. Copyright © 2016 Elsevier Inc. All rights reserved.

    This meta-analysis examined the effects of process-based executive-function and working memory training (49 articles, 61 independent samples) in older adults (> 60 years). The interventions resulted in significant effects on performance on the trained task and near-transfer tasks; significant results were obtained for the net pretest-to-posttest gain relative to active and passive control groups and for the net effect at posttest relative to active and passive control groups. Far-transfer effects were smaller than near-transfer effects but were significant for the net pretest-to-posttest gain relative to passive control groups and for the net gain at posttest relative to both active and passive control groups. We detected marginally significant differences in training-induced improvements between working memory and executive-function training, but no differences between the training-induced improvements observed in older adults and younger adults, between the benefits associated with adaptive and nonadaptive training, or between the effects in active and passive control conditions. Gains did not vary with total training time. © The Author(s) 2014.

This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD) during 6 weeks and discussed. Then, students participated in a post-test. Students' perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001); but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128). In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

    Full Text Available The purpose of the study was to determine if six weeks of plyometric training can improve an athlete's agility. Subjects were divided into two groups, a plyometric training and a control group. The plyometric training group performed in a six week plyometric training program and the control group did not perform any plyometric training techniques. All subjects participated in two agility tests: T-test and Illinois Agility Test, and a force plate test for ground reaction times both pre and post testing. Univariate ANCOVAs were conducted to analyze the change scores (post - pre in the independent variables by group (training or control with pre scores as covariates. The Univariate ANCOVA revealed a significant group effect F2,26 = 25.42, p=0.0000 for the T-test agility measure. For the Illinois Agility test, a significant group effect F2,26 = 27.24, p = 0.000 was also found. The plyometric training group had quicker posttest times compared to the control group for the agility tests. A significant group effect F2,26 = 7.81, p = 0.002 was found for the Force Plate test. The plyometric training group reduced time on the ground on the posttest compared to the control group. The results of this study show that plyometric training can be an effective training technique to improve an athlete's agility

    Full Text Available Background: Disease transmission and barrier techniques are the key concerns during ultrasonic instrumentation as this procedure has the hazard of aerosol production which has a multitude of deleterious effects on the body. The aerosol produced can affect both the patient and the clinician. The aim of this study was to assess the importance of pre-procedural rinsing before scaling by ultrasonic instrumentation and to compare the efficacy of commercially available herbal mouth rinse and a Chlorhexidine gluconate mouth rinse with a control group. The study was conducted from 1 st February to 15 th April 2012 in a tertiary referral care hospital. The study was approved by the institutional ethical committee. This was a randomized single blinded interventional study, where in 36 patients equally divided into three groups participated. Material and Methods: Thirty six patients were recruited in this study aged between 18-35 years. All patients had plaque index scores between1.5-3.0, and were categorized into three groups. Patients with systemic diseases and on antibiotic therapy were excluded. Group A or control group underwent scaling with water as pre-procedural rinse, Group B used 20 ml of 0.2% Chlorhexidine and group C were administered 18 ml of a herbal pre-procedural rinse. Aerosol splatter produced during the procedure were collected on blood agar plates and sent for microbiologic analysis for the assessment of bacterial Colony Forming Units (CFUs. The mean CFUs and standard deviation (SD for each group were measured. Post hoc test was used to compare the differences between three groups, Control (A Chlorhexidine (B and Herbal (C. Results: The mean Colony Forming Units (CFUs for control group was 114.50, Chlorhexidine group was 56.75 and herbal rinse group was 47.38. Conclusion: Pre-procedural rinsing was found to be effective in reducing aerosol contamination during ultrasonic scaling though no statistically significant difference was found

    Full Text Available Pre-acting control in shock/impact isolation systems is studied. With pre-acting control, the isolation system begins to respond to an impact before this impact has been applied to the base. The limiting performance of the isolator with pre-acting control is investigated for a single-degree-of-freedom system subject to an instantaneous impact. The isolation performance index is defined as the maximum of the absolute value of the displacement of the object to be isolated relative to the base, provided that the magnitude of the control force transmitted to the object does not exceed a prescribed value. It is shown that there is a substantial advantage in the use of pre-acting isolators over isolators without pre-action. Particular attention is given to a pre-acting isolator based on a passive elastic element (a spring separating the object to be protected from the base. An example illustrates the calculation of the design parameters of such an isolator.

    Web-based modules may facilitate instruction on core topics in allergy and immunology (AI). Pretests (PTs) have been shown to improve learning in Web-based courses, but their effectiveness in comparison with advance organizers (AOs) is unknown. We performed a randomized controlled trial of a Web-based educational intervention for teaching the practical aspects of allergen immunotherapy (AIT). AI Fellows-in-Training were randomly assigned to receive the introduction to the modules in an AO outline (AO group) or as PT questions (PT group). The primary outcome was the difference in posttest scores between groups. The secondary outcome was the difference in PT and posttest scores in the PT group. Thirty participants in the AO group and 35 in the PT group completed the modules and the posttest. The mean (SD) posttest score for the AO group was 74% (14%) compared with 73% (9%) for the PT group, a mean difference of -1% (95% CI, -7%, 5%; p = 0.67). A multivariate analysis controlling for year-in-training and total time spent on the modules revealed virtually identical results. The mean (SD) PT score for the PT group increased from 49 (10%) to 73% (9%), a mean difference of 24% (95% CI, 19%, 28%; p < 0.0001). Introducing Web-based allergy education with PT questions or an AO resulted in similar posttest scores. Posttest scores in the PT group improved significantly compared with PT scores.

    Full Text Available This study sought to evaluate the effect of dialogue journal writing on writing performance as well as its different sub-components, namely content, organization, vocabulary, language use, and mechanics (Following Polio, 2013. Participants were 84 EFL intermediate learners who were selected based on their performance on Oxford Quick Placement Test (2004 and divided randomly into experimental and control groups. While the participants in the control group took part in descriptive writing pre and post-tests only, their counterparts in experimental group were asked to write 3 journals a week for about 6 months in the period between the pre- and post-tests. The instructor of the experimental group provided feedback to each journal entry mostly on its content and message to which the participants replied in a dialogic manner. Results of independent sample t-test located a significant difference between the experimental and control group regarding the overall writing performance, as well as the sub-components of content, organization, and vocabulary in the post-test. However, the obtained results did not reveal a significant effect of dialogue journal writing on language use and mechanics of writing performance. The results which promise implications for writing instructors, curriculum developers, and material designers are fully discussed.

    Evaluation of educational interventions is necessary prior to wide-scale rollout. Yet very few rigorous studies have been conducted on the effectiveness of tablet-based interventions, especially in the early years and in developing countries. This study reports a randomized control trial to evaluate the effectiveness of a tablet intervention for supporting the development of early mathematical skills in primary school children in Malawi. A total sample of 318 children, spanning Standards 1-3, attending a medium-sized urban primary school, were randomized to one of three groups: maths tablet intervention, non-maths tablet control, and standard face-to-face practice. Children were pre-tested using tablets at the start of the school year on two tests of mathematical knowledge and a range of basic skills related to scholastic progression. Class teachers then delivered the intervention over an 8-weeks period, for the equivalent of 30-min per day. Technical support was provided from the local Voluntary Service Overseas (VSO). Children were then post-tested on the same assessments as given at pre-test. A final sample of 283 children, from Standards 1-3, present at both pre- and post-test, was analyzed to investigate the effectiveness of the maths tablet intervention. Significant effects of the maths tablet intervention over and above standard face-to-face practice or using tablets without the maths software were found in Standards 2 and 3. In Standard 3 the greater learning gains shown by the maths tablet intervention group compared to both of the control groups on the tablet-based assessments transferred to paper and pencil format, illustrating generalization of knowledge gained. Thus, tablet technology can effectively support early years mathematical skills in developing countries if the software is carefully designed to engage the child in the learning process and the content is grounded in a solid well-constructed curriculum appropriate for the child's developmental

    This study examined the effectiveness of a domestic violence shelter and tested the impact of a self-compassion support group curriculum on outcomes valued by shelters such as autonomy, emotional restoration, and safety. Data were collected from 251 women staying in a domestic violence shelter who had the opportunity to attend a self-compassion support group during their stay. Women completed a pre- and posttest survey assessing self-compassion, empowerment, positive emotion, and perceptions of safety. First, women experienced a positive change ( N = 36) from pretest to posttest across all four outcome variables, suggesting the domestic violence shelter was effective at improving survivors' well-being. Second, participants who attended a self-compassion support group at least once reported more positive posttest scores compared with those who did not attend a group ( N = 79); however, this effect was limited to participants who stayed in shelter a short time. Women who stayed in shelter a longer amount of time experienced more positive posttest scores regardless of group attendance. Although the sample size was limited, analyses directly comparing the traditional shelter support group with the self-compassion support group show that both were equally effective. These findings provide support for shelter effectiveness in terms of improving well-being. They also suggest women who stay in shelter a short period of time may not experience as many shelter benefits unless they attend a support group. Therefore, shelters should consider offering support groups to women very soon after shelter entry. Furthermore, more research is needed to disentangle the benefits of self-compassion interventions over and above a general support group curriculum.

  13. Changes in cognitive control in pre-manifest Huntington's disease examined using pre-saccadic EEG potentials - a longitudinal study.

    2014-01-01

    It is well-known that Huntington's disease (HD) affects saccadic processing. However, saccadic dysfunctions in HD may be seen as a result of dysfunctional processes occurring at the oculomotor level prior to the execution of saccades, i.e., at a pre-saccadic level. Virtually nothing is known about possible changes in pre-saccadic processes in HD. This study examines pre-saccadic processing in pre-manifest HD gene mutation carriers (pre-HDs) by using clinically available EEG measures. Error rates, pre-saccadic EEG potentials and saccade onset EEG potentials were measured in 14 pre-HDs and case-matched controls performing prosaccades and antisaccades in a longitudinal study over a 15-month period. The results show that pre-saccadic potentials were changed in pre-HDs, relative to controls and also revealed changes across the 15-month longitudinal period. In particular, pre-saccadic ERP in pre-HDs were characterized by lower amplitudes and longer latencies, which revealed longitudinal changes. These changes were observed for anti-saccades, but not for pro-saccades. Overt saccadic trajectories (potentials) were not different to those in controls, showing that pre-saccadic processes are sensitive to subtle changes in fronto-striatal networks in pre-HDs. Deficits in pre-saccadic processes prior the execution of an erroneous anti-saccade can be seen as an effect of dysfunctional cognitive control in HD. This may underlie saccadic abnormalities and hence a major phenotype of HD. Pre-saccadic EEG potentials preceding erroneous anti-saccades are sensitive to pre-manifest disease progression in HD.

    Full Text Available Little is known about the influence of different stressors on fine motor skills, the concentration of testosterone (T, and their interaction in adolescents. Therefore, 62 high school students aged 14-15 years were randomly assigned to two experimental groups (exercise, psychosocial stress and a control group. Exercise stress was induced at 65-75% of the maximum heart rate by running for 15 minutes (n = 24. Psychosocial stress was generated by an intelligence test (HAWIK-IV, which was uncontrollable and characterized by social-evaluative-threat to the students (n = 21. The control group followed was part of a regular school lesson with the same duration (n = 28. Saliva was collected after a normal school lesson (pre-test as well as after the intervention/control period (post-test and was analyzed for testosterone. Fine motor skills were assessed pre- and post-intervention using a manual dexterity test (Flower Trail from the Movement Assessment Battery for Children-2. A repeated measure ANCOVA including gender as a covariate revealed a significant group by test interaction, indicating an increase in manual dexterity only for the psychosocial stress group. Correlation analysis of all students shows that the change of testosterone from pre- to post-test was directly linked (r = -.31, p = .01 to the changes in manual dexterity performance. Participants showing high increases in testosterone from pre- to post-test made fewer mistakes in the fine motor skills task. Findings suggest that manual dexterity increases when psychosocial stress is induced and that improvement of manual dexterity performance corresponds with the increase of testosterone.

    Full Text Available The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of  the virtual school of Tehran University of Medical Sciences called “SARMAD” to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD during 6 weeks and discussed. Then, students participated in a post-test. Students’ perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001; but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128. In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

    Full Text Available Our aim in this study was to test two programmes designed to lead preschool children to use conventional letters to spell the initial consonants of words. These programmes differed in terms of the characteristics of the vowels that followed those consonants. The participants were 45 five-year-old Portuguese children whose spelling was pre-syllabic - they used strings of random letters in their spelling, making no attempt to match the oral to the written language. They were divided into two experimental and a control group. Their age, level of intelligence, and phonological awareness were controlled. Their spelling was assessed in a pre- and a post-test. In-between, children from the experimental groups participated in two programmes where they had to think about the relationships between the initial consonant and the corresponding phoneme in different words: In Experimental Group 1, the initial consonants were followed by an open vowel, and in Experimental Group 2, these same consonants were followed by a closed vowel. The control group classified geometric shapes. Experimental Group 1 achieved better results than Experimental Group 2 following open vowels, being more able to generalize the phonological procedures to sounds that were not taught during the programmes. Both experimental groups used conventional letters to represent several phonemes in the post-test whereas the control group continued to produce pre-syllabic spellings.

    We investigated factors hypothesized to moderate the effects of cognitive behavioral group-based (CB group) and bibliotherapy depression prevention programs. Using data from two trials (N = 631) wherein adolescents (M age = 15.5, 62% female, 61% Caucasian) with depressive symptoms were randomized into CB group, CB bibliotherapy, or an educational brochure control condition, we evaluated the moderating effects of individual, demographic, and environmental factors on depressive symptom reductions and major depressive disorder (MDD) onset over 2-year follow-up. CB group and bibliotherapy participants had lower depressive symptoms than controls at posttest but these effects did not persist. No MDD prevention effects were present in the merged data. Relative to controls, elevated depressive symptoms and motivation to reduce depression amplified posttest depressive symptom reduction for CB group, and elevated baseline symptoms amplified posttest symptom reduction effects of CB bibliotherapy. Conversely, elevated substance use mitigated the effectiveness of CB group relative to controls on MDD onset over follow-up. Findings suggest that both CB prevention programs are more beneficial for youth with at least moderate depressive symptoms, and that CB group is more effective for youth motivated to reduce their symptoms. Results also imply that substance use reduces the effectiveness of CB group-based depression prevention. PMID:26480199

    To compare lecture-based learning (LBL) and discussion-based learning (DBL) by assessing immediate and long-term knowledge retention and application of practical knowledge in third- and fourth-year medical students. A prospective, randomized control trial was designed to study the effects of DBL. Medical students were randomly assigned to intervention (DBL) or control (LBL) groups. Both the groups were instructed regarding the management of gastroschisis. The control group received a PowerPoint presentation, whereas the intervention group was guided only by an objectives list and a gastroschisis model. Students were evaluated using a multiple-choice pretest (Pre-Test MC) immediately before the teaching session, a posttest (Post-Test MC) following the session, and a follow-up test (Follow-Up MC) at 3 months. A practical examination (PE), which tested simple skills and management decisions, was administered at the end of the clerkship (Initial PE) and at 3 months after clerkship (Follow-Up PE). Students were also given a self-evaluation immediately following the Post-Test MC to gauge satisfaction and comfort level in the management of gastroschisis. University of Iowa Hospitals and Clinics and the Carver College of Medicine, Iowa City, IA. A total of 49 third- and fourth-year medical students who were enrolled in the general surgery clerkship were eligible for this study. Enrollment into the study was completely voluntary.

    Chemistry is a complex knowledge domain. Specifically, research notes that Chemical Equilibrium presents greater cognitive challenges than other topics in chemistry. Cognitive Load Theory describes the impact a subject, and the learning environment, have on working memory. Intrinsic load is the facet of Cognitive Load Theory that explains the complexity innate to complex subjects. The purpose of this study was to build on the limited research into intrinsic cognitive load, by examining the effects of using multimedia screencasts as a pre-training technique to manage the intrinsic cognitive load of chemical equilibrium instruction for advanced high school chemistry students. A convenience sample of 62 fourth-year high school students enrolled in an advanced chemistry course from a co-ed high school in urban San Francisco were given a chemical equilibrium concept pre-test. Upon conclusion of the pre-test, students were randomly assigned to two groups: pre-training and no pre-training. The pre-training group received a 10 minute and 52 second pre-training screencast that provided definitions, concepts and an overview of chemical equilibrium. After pre-training both group received the same 50-minute instructional lecture. After instruction, all students were given a chemical equilibrium concept post-test. Independent sample t-tests were conducted to examine differences in performance and intrinsic load. No significant differences in performance or intrinsic load, as measured by ratings of mental effort, were observed on the pre-test. Significant differences in performance, t(60)=3.70, p=.0005, and intrinsic load, t(60)=5.34, p=.0001, were observed on the post-test. A significant correlation between total performance scores and total mental effort ratings was also observed, r(60)=-0.44, p=.0003. Because no significant differences in prior knowledge were observed, it can be concluded that pre-training was successful at reducing intrinsic load. Moreover, a significant

    This report presents selected results of posttest RELAP4 modeling of LOFT loss-of-coolant experiment L1-3A, a double-ended isothermal cold leg break with lower plenum emergency core coolant injection. Comparisons are presented between the pretest prediction, the posttest analysis, and the experimental data. It is concluded that pressurizer modeling is important for accurately predicting system behavior during the initial portion of saturated blowdown. Using measured initial conditions rather than nominal specified initial conditions did not influence the system model results significantly. Using finer nodalization in the reactor vessel improved the prediction of the system pressure history by minimizing steam condensation effects. Unequal steam condensation between the downcomer and core volumes appear to cause the manometer oscillations observed in both the pretest and posttest RELAP4 analysis

    The importance of using technologies such as e-learning in different disciplines is discussed in the literature. Researchers have measured the effectiveness of e-learning in a number of fields.Considering the lack of research on the effectiveness of online learning in dental education particularly in Iran, the advantages of these learning methods and the positive university atmosphere regarding the use of online learning. This study, therefore, aims to compare the effects of two methods of teaching (virtual versus traditional) on student learning. This post-test only design study approached 40, fifth year dental students of Shiraz University of Medical Sciences. From this group, 35 students agreed to participate. These students were randomly allocated into two groups, experimental (virtual learning) and comparison (traditional learning). To ensure similarity between groups, we compared GPAs of all participants by the Mann-Whitney U test (P > 0.05). The experimental group received a virtual learning environment courseware package specifically designed for this study, whereas the control group received the same module structured in a traditional lecture form. The virtual learning environment consisted of online and offline materials. Two identical valid, reliable post-tests that consisted of 40 multiple choice questions (MCQs) and 4 essay questions were administered immediately (15 min) after the last session and two months later to assess for knowledge retention. Data were analyzed by SPSS version 20. A comparison of the mean knowledge score of both groups showed that virtual learning was more effective than traditional learning (effect size = 0.69). The newly designed virtual learning package is feasible and will result in more effective learning in comparison with lecture-based training. However further studies are needed to generalize the findings of this study.

    Providing e-learning modules can be an effective strategy for enhancing gatekeepers' knowledge, self-confidence and skills in adolescent suicide prevention. The aim of this study was to test the effectiveness of an online training program called Mental Health Online which consists of eight short e-learning modules, each capturing an important aspect of the process of recognition, guidance and referral of suicidal adolescents (12-20 years). The primary outcomes of this study are participant's ratings on perceived knowledge, perceived self-confidence, and actual knowledge regarding adolescent suicidality. A randomized controlled trial will be carried out among 154 gatekeepers. After completing the first assessment (pre-test), participants will be randomly assigned to either the experimental group or the waitlist control group. One week after completing the first assessment the experimental group will have access to the website Mental Health Online containing the eight e-learning modules and additional information on adolescent suicide prevention. Participants in both conditions will be assessed 4 weeks after completing the first assessment (post-test), and 12 weeks after completing the post-test (follow-up). At post-test, participants from the experimental group are asked to complete an evaluation questionnaire on the modules. The waitlist control group will have access to the modules and additional information on the website after completing the follow-up assessment. Gatekeepers can benefit from e-learning modules on adolescent suicide prevention. This approach allows them to learn about this sensitive subject at their own pace and from any given location, as long as they have access to the Internet. Given the flexible nature of the program, each participant can compose his/her own training creating an instant customized course with the required steps in adolescent suicide prevention.

    Walters, Kristi L.

    The importance of student motivation and its connection to other learning variables (i.e., attitudes, knowledge, persistence, attendance) is well established. Collaborative work at the undergraduate level has been recognized as a valuable tool in large courses. However, motivation and collaborative group work have rarely been combined. This project utilized student motivation to learn biology to place non-major biology undergraduates in collaborative learning groups at East Carolina University, a mid-sized southeastern American university, to determine the effects of this construct on student learning. A pre-test measuring motivation to learn biology, attitudes toward biology, perceptions of biology and biologists, views of science, and content knowledge was administered. A similar post-test followed as part of the final exam. Two sections of the same introductory biology course (n = 312) were used and students were divided into homogeneous and heterogeneous groups (based on their motivation score). The heterogeneous groups (n = 32) consisted of a mixture of different motivation levels, while the homogeneous groups (n = 32) were organized into teams with similar motivation scores using tiers of high-, middle-, and low-level participants. Data analysis determined mixed perceptions of biology and biologists. These include the perceptions biology was less intriguing, less relevant, less practical, less ethical, and less understandable. Biologists were perceived as being neat and slightly intelligent, but not very altruistic, humane, ethical, logical, honest, or moral. Content knowledge scores more than doubled from pre- to post-test. Half of the items measuring views of science were not statistically significantly different from pre- to post-test. Many of the factors for attitudes toward biology became more agreeable from pre- to post-test. Correlations between motivation scores, participation levels, attendance rates, and final course grades were examined at both the

    The aim of this study was to determine the effectiveness of an assertive training for school-aged children on peer bullying and assertiveness. A quasi-experimental design using pre- and post-testing was conducted. Data were collected using a demographic questionnaire, an assertiveness scale, and the peer victimization scale. The training program was comprised of eight sessions which were implemented to intervention group. Descriptive characteristics were not statistically different between the groups (p>0.05). The peer victimization victim dimension results show that post-test mean scores of the students in the intervention group were lower than the pre-test mean scores (p0.05). A comparison of the mean pre-test/post-test scores of peer-victimization bully dimension of the students' intervention and control groups revealed that the mean post-test scores of the students in the each group decreased (p>0.05). An assertiveness training program increased the assertiveness level and reduced the state of being victims, but did not affect the state of being bullies. The results of this study can help children acquire assertive behaviors instead of negative behaviors such as aggression and shyness, and help them to build effective social communication.

    Observation and description are critical to the practice of medicine, and to ophthalmology in particular. However, medical education does not provide explicit training in these areas, and medical students are often criticized for deficiencies in these skills. We sought to evaluate the effects of formal observation training in the visual arts on the general and ophthalmologic observational skills of medical students. Randomized, single-masked, controlled trial. Thirty-six first-year medical students, randomized 1:1 into art-training and control groups. Students in the art-training group were taught by professional art educators at the Philadelphia Museum of Art, during 6 custom-designed, 1.5-hour art observation sessions over a 3-month period. All subjects completed pre- and posttesting, in which they described works of art, retinal pathology images, and external photographs of eye diseases. Grading of written descriptions for observational and descriptive abilities by reviewers using an a priori rubric and masked to group assignment and pretesting/posttesting status. Observational skills, as measured by description testing, improved significantly in the training group (mean change +19.1 points) compared with the control group (mean change -13.5 points), P = 0.001. There were significant improvements in the training vs. control group for each of the test subscores. In a poststudy questionnaire, students reported applying the skills they learned in the museum in clinically meaningful ways at medical school. Art observation training for first-year medical students can improve clinical ophthalmology observational skills. Principles from the field of visual arts, which is reputed to excel in teaching observation and descriptive abilities, can be successfully applied to medical training. Further studies can examine the impact of such training on clinical care. Copyright © 2017 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.

    The study aimed to evaluate the influence of virtual learning object (VLO) in the theoretical knowledge and skill practice of undergraduate dentistry students as it relates to zinc phosphate cement (ZPC). Only students enrolled in the dentistry course the course were included in the trial. Forty-six students received a live class regarding ZPC and were randomized by electronic sorting into the following 4 groups: VLO Immediate (GIVLOn=9), VLO longitudinal (GLVLOn=15) and two control groups without VLO (GICn=9 and GLCn=13). The immediate groups had access to VLO or a book for 20 min before the ability assessment, whereas the longitudinal groups had access to VLO or a book for 15 days. A pre- and posttest on theoretical knowledge and two laboratory skill tests, evaluated by blinded examiners, were performed regarding zinc phosphate cement manipulation in all groups. The students who used the VLO obtained better results in all the tests performed than the control students. The theoretical posttest showed a significant difference between the longitudinal groups, GLC (6.0 ± 1.15) and GLVLO (7.33 ± 1.43). The lower film thickness presented with a significant difference in the VLO groups: (GIC 25 ± 9.3) and GIVLO (16.24 ± 5.17); GLC (50 ± 27.08) and GLVLO (22.5±9.65). The higher setting time occurred in the VLO groups, and the immediate group showed a significant difference (GIC 896 ± 218.90) and GIVLO (1138.5 ± 177.95). The ZPC manipulated by the students who used the VLO had better mechanical properties in the laboratory tests. Therefore, the groups that used the VLO had clinical handling skills superior to its controls and greater retention of knowledge after 15 days. Copyright © 2015 Elsevier Ireland Ltd.

    Many hospitals opt for early postnatal discharge of newborns with a potential risk of readmission for neonatal hyperbilirubinemia. Assays/algorithms with the possibility to improve prediction of significant neonatal hyperbilirubinemia are needed to optimize screening protocols and safe discharge of neonates. This study investigated the predictive value of umbilical cord blood (UCB) testing for significant hyperbilirubinemia. Neonatal UCB bilirubin, UCB direct antiglobulin test (DAT), and blood group were determined, as well as the maternal blood group and the red blood cell antibody status. Moreover, in newborns with clinically apparent jaundice after visual assessment, plasma total bilirubin (TB) was measured. Clinical factors positively associated with UCB bilirubin were ABO incompatibility, positive DAT, presence of maternal red cell antibodies, alarming visual assessment and significant hyperbilirubinemia in the first 6 days of life. UCB bilirubin performed clinically well with an area under the receiver-operating characteristic curve (AUC) of 0.82 (95 % CI 0.80-0.84). The combined UCB bilirubin, DAT, and blood group analysis outperformed results of these parameters considered separately to detect significant hyperbilirubinemia and correlated exponentially with hyperbilirubinemia post-test probability. Post-test probabilities for neonatal hyperbilirubinemia can be calculated using exponential functions defined by UCB bilirubin, DAT, and ABO compatibility results. • The diagnostic value of the triad umbilical cord blood bilirubin measurement, direct antiglobulin testing and blood group analysis for neonatal hyperbilirubinemia remains unclear in literature. • Currently no guideline recommends screening for hyperbilirubinemia using umbilical cord blood. What is New: • Post-test probability for hyperbilirubinemia correlated exponentially with umbilical cord blood bilirubin in different risk groups defined by direct antiglobulin test and ABO blood group

    Research about the implementation of the Peer Assisted Learning (PAL) strategy in Plant Physiology lecture has carried out, in which it aims to improve students’ physiologic literacy. The PAL strategy began with a briefing by the lecturers to the students tutor about pretest questions, followed by the interaction between student tutors with their peers to discuss response problems, terminated by answering responsiveness questions individually. This study used a quasi-experimental method, one - group pre-test post-test design. This design includes a group of students observed in the pre-test phase (tests carried out before PAL treatment) which is then followed by treatment with PAL and ends with post-test. The other students group (control) was given the pre-test and post-test only. The results showed that the PAL strategy can increase student’s physiologic literacy significantly. One of the weaknesses of students’ physiologic literacy is that they have not been able to read the graph. The faculties are encouraged to begin introducing and teaching material using a variety of strategies with scientific literacy aspects, for example teaching research-based material. All students respond positively to the PAL strategy.

    Full Text Available The aim of this study was to ascertain the effects of a holistic short-term group intervention in the treatment of Irritable Bowel Syndrome (/BS with comorbid depression and anxiety. The sample consisted of 24 South African women who had been diagnosed with severe IBS. Furthermore, each participant had to have associated moderate to severe depression and anxiety. The group design was a pre-test, post-test control group design where the experimental group (n = 12 received group intervention and the members of the control group (n = 12 received no intervention until after completion of the research. All the participants completed the Functional Bowel Disorder Severity Index and the Depression and Anxiety subscales of the Personality Assessment Inventory before commencement of group therapy for Group 1 and one month after completion of this intervention. The effect of the intervention was determined by utilising comparative statistics. The findings indicate that holistic short-term group therapy results in significant improvement in terms of depreSSion and anxiety scores, but that IBS symptom severity remains unchanged. It is recommended that further research be conducted to ascertain whether holistic group therapy of a longer duration has a greater impact on the IBS symptom severity.

    Full Text Available Stress is one of the most important phenomena in this century that has had a great impact on people's mental and physical health and has become one of the main topics of organizational management. Primarily, nursing and taking care of patients is stressful itself. Therefore, in the working environment, any menace to organizational goals and reduction in the quality of nursing cares are due to stress. There are different therapeutic ways to deal with stress which cognitive behavioral therapy is one of them. The goal of this study was to examine the effects of cognitive behavior therapy on stress among nurses who worked at Yasuj Shahid Beheshti hospital in 2014. This was an experimental research that was carried out among 100 nurses working at Yasuj Shahid Beheshti hospital in 2014. The sampling type was available samples. After filling the DASS-42 questionnaire, we chose 30 cases that had the worst status from point of stress and were randomly divided into two groups: case and control groups. Each group consisted of 15 nurses. The cases were trained in 8 weeks, an hour a week, by a single clinical psychologist specialized in cognitive behavioral therapy. After the therapy, questionnaires were filled again by the two groups. Finally, two groups were compared together in view point of stress scores. For analysis of data we used the SPSS software and descriptive statistics, t-test and ANOVA. The mean and standard deviations of stress in case group on the pre-test were7.96 ± 18.73 and on the posttest were 6.295 ± 12.266 respectively, the mean and standard deviations of stress in the control group for pre-test were 8.413 ± 21.066 and for posttest were 9.019 ± 20.733 respectively. The mean and standard deviations of stress in case group on the pre-test were7.96 ± 18.73 and on the posttest were 6.295 ± 12.266 respectively, the mean and standard deviations of stress in the control group for pretest were 8.413 ± 21.066 and for posttest were 9.01 9

    Full Text Available BACKGROUND AND OBJECTIVE: Cancers are a broad group of diseases, each having their own etiology, treatment, and prognosis. The majority of cancer patients experience a period of mental stress during their disease. Given the effective role of life expectancy in dealing with chronic diseases, such as stomach cancer, this study aimed to evaluate the effects of cognitive-behavioral group therapy on increased life expectancy of male patients with gastric cancer. METHODS: This quasi-experiment was conducted on 92 male patients with gastric cancer referring to Tuba Medical Center, Sari, Iran in 2014. Patients were randomly divided into two groups of test (n=46 and control (n=46. The two groups completed the Adult Hope Scale (AHS by Snyder in pretest stage. At the next stage, samples of the test group were exposed to 10 sessions of cognitive-behavioral group therapy (each session: 90 min, while the control group did not receive any special treatment. Both study groups completed the questionnaire again at the posttest stage, followed by the comparison of results. FINDINGS: In terms of life expectancy, mean scores of the test and control groups at the pretest stage were 37.21±4.7 and 36.26±4.73, respectively. Meanwhile, mean scores of the mentioned groups at the posttest stage were 40.02±3.87 and 36.23±4.8, respectively. A significant increase was observed in the mean scores of test and control groups at the posttest stage compared to before the intervention. Moreover, a significant difference was found between the study groups regarding life expectancy and its components (p<0.01. CONCLUSION: According to the results, cognitive-behavioral group therapy could increase life expectancy in patients with gastric cancer.

    Full Text Available Training programs that include aerobics and strength exercises, either at the same session or alternate days are defined as concurrent training (CT. The objective of this study was to verify the effects of a CT program on biochemical parameters,cardiovascular fitness, body composition and neuromuscular aspects. Twenty two elderly women physically active were randomly allocated to one of the five groups: AS (aerobic exercises followed by strength training; n=5, SA (strength activities followed by aerobics exercises; n=5, AG (aerobics exercise only;n=5, SG (strength activities only; n=4, CG (control group; n=3. The program lasted 12 weeks. Tests of dynamic and static strength, flexibility, aerobic power, body composition and biochemical parameters were conducted. In the aerobics power test, AS and SA groups showed differences in the post-test compared to the CG. In dynamic strength test of upper limbs, the groups S, SA, AS showed statistical differences from the CG in the post-test (p=0.009, 0.006 and 0.002 respectively. Only the AS group presented some difference from the pre to post-tests (P=003. AG, SG, SA, AS showed differences in the post-test inrelation to the CG for the lower limbs strength test (p<0.001. From pre to post-test within the same group, the groups SG, SA and AS showed differences (p=0.001, 0.03, 0.02. Stretching, static strength, biochemical factors and body composition showed no association with any of the groups. We concluded that CT was equivalent to the strength and aerobics exercises performed exclusively.

    Mental health professionals experiencing work-related stress may experience burn out, leading to a negative impact on their organization and patients. The aim of this study was to examine the effects of yoga classes on work-related stress, stress adaptation, and autonomic nerve activity among mental health professionals. A randomized controlled trial was used, which compared the outcomes between the experimental (e.g., yoga program) and the control groups (e.g., no yoga exercise) for 12 weeks. Work-related stress and stress adaptation were assessed before and after the program. Heart rate variability (HRV) was measured at baseline, midpoint through the weekly yoga classes (6 weeks), and postintervention (after 12 weeks of yoga classes). The results showed that the mental health professionals in the yoga group experienced a significant reduction in work-related stress (t = -6.225, p control group revealed no significant changes. Comparing the mean differences in pre- and posttest scores between yoga and control groups, we found the yoga group significantly decreased work-related stress (t = -3.216, p = .002), but there was no significant change in stress adaptation (p = .084). While controlling for the pretest scores of work-related stress, participants in yoga, but not the control group, revealed a significant increase in autonomic nerve activity at midpoint (6 weeks) test (t = -2.799, p = .007), and at posttest (12 weeks; t = -2.099, p = .040). Because mental health professionals experienced a reduction in work-related stress and an increase in autonomic nerve activity in a weekly yoga program for 12 weeks, clinicians, administrators, and educators should offer yoga classes as a strategy to help health professionals reduce their work-related stress and balance autonomic nerve activities. © 2015 The Authors.

    Kinesthetic illusions by visual stimulation (KiNVIS) enhances corticomotor excitability and activates motor association areas. The purpose of this study was to investigate the effect of KiNVIS induction on muscular output function after short-term immobilization. Thirty subjects were assigned to 3 groups: an immobilization group, with the left hand immobilized for 12h (immobilization period); an illusion group, with the left hand immobilized and additionally subjected to KiNVIS of the immobilized part during the immobilization period; and a control group with no manipulation. The maximum voluntary contraction (MVC), fluctuation of force (force fluctuation) during a force modulation task, and twitch force were measured both before (pre-test) and after (post-test) the immobilization period. Data were analyzed by performing two-way (TIME×GROUP) repeated measures ANOVA. The MVC decreased in the immobilization group only (pre-test; 37.8±6.1N, post-test; 32.8±6.9N, p<0.0005) after the immobilization period. The force fluctuation increased only in the immobilization group (pre-test; 2.19±0.54%, post-test; 2.78±0.87%, p=0.007) after the immobilization period. These results demonstrate that induction of KiNVIS prevents negative effect on MVC and force fluctuation after 12h of immobilization. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available This study investigates the effect of synchronized metronome training (SMT on motor timing and how this training might affect golf shot accuracy. Twenty-six experienced male golfers participated (mean age 27 years; mean golf handicap 12.6 in this study. Pre- and post-test investigations of golf shots made by three different clubs were conducted by use of a golf simulator. The golfers were randomized into two groups: a SMT group and a Control group. After the pre-test, the golfers in the SMT group completed a 4-week SMT program designed to improve their motor timing, the golfers in the Control group were merely training their golf-swings during the same time period. No differences between the two groups were found from the pre-test outcomes, either for motor timing scores or for golf shot accuracy. However, the post-test results after the 4-weeks SMT showed evident motor timing improvements. Additionally, significant improvements for golf shot accuracy were found for the SMT group and with less variability in their performance. No such improvements were found for the golfers in the Control group. As with previous studies that used a SMT program, this study's results provide further evidence that motor timing can be improved by SMT and that such timing improvement also improves golf accuracy

    Typhoons hit Taiwan several times every year, which could cause serious flood disasters. Because mountainous terrains and steep landforms can rapidly accelerate the speed of flood flow during typhoon events, rivers cannot be a stable source of water supply. Reservoirs become the most effective floodwater storage facilities for alleviating flood damages in Taiwan. The pre-storm flood-control release can significantly increase reservoir storage capacity available to store floodwaters for reducing downstream flood damage, while the uncertainties of total forecasted rainfalls are very high in different stages of an oncoming typhoon, which may cause the risk of water shortage in the future. This study proposes adjustable pre-storm reservoir flood-control release rules in three designed operating stages with various hydrological conditions in the Feitsui Reservoir, a pivot reservoir for water supply to Taipei metropolitan in Taiwan, not only to reduce the risk of reservoir flood control and downstream flooding but also to consider water supply. The three operating stages before an oncoming typhoon are defined upon the timings when: (1) typhoon news is issued (3-7days before typhoon hit); (2) the sea warning is issued (2-4 days before typhoon hit); and (3) the land warning is issued (1-2 days before typhoon hit). We simulate 95 historical typhoon events with 3000 initial water levels and build some pre-storm flood-control release rules to adjust the amount of pre-release based on the total forecasted rainfalls at different operating stages. A great number of simulations (68.4 millions) are conducted to extract their major consequences and then build the adjustable pre-storm reservoir flood-control release rules. Accordingly, given a total forecasted rainfall and a water level, reservoir decision makers can easily identify the corresponding rule to tell the amount of pre-release in any stage. The results show that the proposed adjustable pre-release rules can effectively

    Full Text Available Breaking bad news is one of the most burdensome tasks physicians face in their everyday practice. It becomes even more challenging in the context of HIV+ patients because of stigma and discrimination. The aim of the current study is to evaluate the quality of giving HIV seroconversion news according to SPIKES protocol. Numbers of 154 consecutive HIV+ patients from Imam Khomeini Hospital testing and counseling center were enrolled in this study. Patients were inquired about how they were given the HIV news and whether or not they received pre- and post-test counseling sessions. Around 51% of them were men, 80% had high school education, and 56% were employed. Regarding marital status, 32% were single, and 52% were married at the time of the interview. Among them, 31% had received the HIV news in a counseling center, and only 29% had pre-test counseling. SPIKES criteria were significantly met when the HIV news was given in an HIV counseling and testing center (P.value<0.05. Low coverage of HIV counseling services was observed in the study. SPIKES criteria were significantly met when the HIV seroconversion news was given in a counseling center. The need to further train staff to deliver HIV news seems a priority in the field of HIV care and treatment.

    Transgender women in the U.S. have an alarmingly high incidence rate of HIV infection; condomless anal and vaginal sex is the primary risk behavior driving transmission. Young transgender women are the subpopulation at the highest risk for HIV. Despite this, there are no published randomized controlled efficacy trials testing interventions to reduce sexual risk for HIV among this group. This paper describes the design of a group-based intervention trial to reduce sexual risk for HIV acquisition and transmission in young transgender women. This study, funded by the National Institutes of Health, is a randomized controlled trial of a culturally-specific, empowerment-based, and group-delivered six-session HIV prevention intervention, Project LifeSkills, among sexually active young transgender women, ages 16-29 years in Boston and Chicago. Participants are randomized (2:2:1) to either the LifeSkills intervention, standard of care only, or a diet and nutrition time- and attention-matched control. At enrollment, all participants receive standardized HIV pre- and post-test counseling and screening for HIV and urogenital gonorrhea and chlamydia infections. The primary outcome is difference in the rate of change in the number of self-reported condomless anal or vaginal sex acts during the prior 4-months, assessed at baseline, 4-, 8-, and 12-month follow-up visits. Behavioral interventions to reduce sexual risk for HIV acquisition and transmission are sorely needed for young transgender women. This study will provide evidence to determine feasibility and efficacy in one of the first rigorously designed trials for this population.

    This randomized controlled trial examined the impact of the Coming Out Proud (COP) program on self-stigma, stigma stress, and depression. Research participants who experienced mental health challenges were randomly assigned to a three session COP program (n=51) or a waitlist control (n=75). Outcome measures that assessed the progressively harmful stages of self-stigma, stigma stress appraisals, and depression were administered at pre-test, post-test, and one-month follow-up. People completing COP showed significant improvement at post-test and follow-up in the more harmful aspects of self-stigma compared to the control group. COP participants also showed improvements in stigma stress appraisals. Women participating in COP showed significant post-test and follow-up reductions in depression after COP compared to the control group. Men did not show this effect. Future research should determine whether these benefits also enhance attitudes related to recovery, empowerment, and self-determination. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The NoTrap! (Noncadiamointrappola!) program is a school-based intervention, which utilizes a peer-led approach to prevent and combat both traditional bullying and cyberbullying. The aim of the present study was to evaluate the efficacy of the third Edition of the program in accordance with the recent criteria for evidence-based interventions. Towards this aim, two quasi-experimental trials involving adolescents (age M = 14.91, SD = .98) attending their first year at different high schools were conducted. In Trial 1 (control group, n = 171; experimental group, n = 451), latent growth curve models for data from pre-, middle- and post-tests showed that intervention significantly predicted change over time in all the target variables (victimization, bullying, cybervictimization, and cyberbullying). Specifically, target variables were stable for the control group but decreased significantly over time for the experimental group. Long-term effects at the follow up 6 months later were also found. In Trial 2 (control group, n = 227; experimental group, n = 234), the moderating effect of gender was examined and there was a reported decrease in bullying and cyberbullying over time (pre- and post-test) in the experimental group but not the control group, and this decrease was similar for boys and girls. © 2016 Wiley Periodicals, Inc.

  3. Can Visual Illusions Be Used to Facilitate Sport Skill Learning?

    2016-01-01

    Recently it has been reported that practicing putting with visual illusions that make the hole appear larger than it actually is leads to longer-lasting performance improvements. Interestingly, from a motor control and learning perspective, it may be possible to actually predict the opposite to occur, as facing a smaller appearing target should enforce performers to be more precise. To test this idea the authors invited participants to practice an aiming task (i.e., a marble-shooting task) with either a visual illusion that made the target appear larger or a visual illusion that made the target appear smaller. They applied a pre-post test design, included a control group training without any illusory effects and increased the amount of practice to 450 trials. In contrast to earlier reports, the results revealed that the group that trained with the visual illusion that made the target look smaller improved performance from pre- to posttest, whereas the group practicing with visual illusions that made the target appear larger did not show any improvements. Notably, also the control group improved from pre- to posttest.

    The course of Technology and Material Testing prepare students with the ability to do a variety of material testing in the study of mechanical engineering. Students find it difficult to understand the materials to make them unable to carry out the material testing in accordance with the purpose of study. This happens because they knowledge is not adequately supported by the competence to find and construct learning experience. In this study, quasy experiment research method with pre-post-test with control group design was used. The subjects of the study were students divided in two groups; control and experiment with twenty-two students in each group. Study result: their grades showed no difference in between the pre-test or post-test in control group, but the difference in grade existed between the pre-test and post-test in experiment group. Yet, there is no significant difference in the study result on both groups. The researcher recommend that it is necessary to develop Problem-Based Learning that suits need analysis on D3 Program for Mechanical Engineering Department at the State University of Padang, to ensure the compatibility between Model of Study and problems and need. This study aims to analyze how Problem-Based Learning effects on the course of Technology and Material Testing for the students of D3 Program of Mechanical Engineering of the State University of Padang.

    Infectious diseases are common among schoolchildren as a result of their poor hand hygiene, especially in those who have developmental disabilities. A quasi-experimental study using a pre- to post-test design with a control group was used to test the feasibility and sustainability of simplified 5-step handwashing techniques to measure the hand hygiene outcome for students with mild intellectual disability. Sickness-related school absenteeism was compared. The intervention group experienced a significant increase in the rating of their handwashing quality in both hands from pre- to post-test: left dorsum (+1.05, P absenteeism rate (0.0167) than the control group in the same year (0.028, P = .04).Students in this study showed better performance in simplified handwashing techniques and experienced lower absenteeism than those using usual practice in special education school settings. The simplified 5-step hand hygiene technique has been proven effective in reducing the spread of infectious diseases.

    Play therapy is a nursing intervention employed in multidisciplinary approaches to develop the social, emotional, and behavioral skills of children. In this study, we aim to determine the effects of play therapy on the social, emotional, and behavioral skills of pre-school children through the nursing process. A single-blind, prospective, randomized controlled study was undertaken. The design, conduct, and reporting of this study adhere to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. The participants included 4- to 5-year-old kindergarten children with no oral or aural disabilities and parents who agreed to participate in the study. The Pre-school Child and Family Identification Form and Social Competence and the Behavior Evaluation Scale were used to gather data. Games in the play therapy literature about nursing diagnoses (fear, social disturbance, impaired social interactions, ineffective coping, anxiety), which were determined after the preliminary test, constituted the application of the study. There was no difference in the average scores of the children in the experimental and control groups in their Anger-Aggression (AA), Social Competence (SC), and Anxiety-Withdrawal (AW) scores beforehand (t = 0.015, p = .988; t = 0.084, p = .933; t = 0.214, p = .831, respectively). The difference between the average AA and SC scores in the post-test (t = 2.041, p = .045; t = 2.692, p = .009, respectively), and the retests were statistically significant in AA and SC average scores in the experimental and control groups (t = 4.538, p = .000; t = 4.693; p = .000, respectively). In AW average scores, no statistical difference was found in the post-test (t = 0.700, p = .486), whereas in the retest, a significant difference was identified (t = 5.839, p = .000). Play therapy helped pre-school children to improve their social, emotional, and behavioral skills. It also provided benefits for the children to decrease their fear and anxiety levels, to improve

    To measure academic achievement of the multiple intelligence-based learning medium via a tablet device. This is a quasi-experimental research study (non-randomized control group pretest-posttest design) in 62 grade 1 elementary students (33 males and 29 females). Thirty-one students were included in an experimental group using purposive sampling by choosing a student who had highest multiple intelligence test scores in logical-mathematic. Then, this group learned by the new learning medium via a tablet which the application matched to logical-mathematic multiple intelligence. Another 31 students were included in a control group using simple random sampling and then learning by recitation. Both groups did pre-test and post-test vocabulary. Thirty students in the experimental group and 24 students in the control group increased post-test scores (odds ratio = 8.75). Both groups made significant increasing in post-test scores. The experimental group increased 9.07 marks (95% CI 8.20-9.93) significantly higher than the control group which increased 4.39 marks (95% CI 3.06-5.72) (t = -6.032, df = 51.481, p learning from either multiple intelligence-based learning medium via a tablet or recitation can contribute academic achievement, learningfrom the new medium contributed more achievement than recitation. The new learning medium group had higher post-test scores 8.75 times than the recitation group. Therefore, the new learning medium is more effective than the traditional recitation in terms of academic achievement. This study has limitations because samples came from the same school. However, the previous study in Thailand did notfind a logical-mathematical multiple intelligence difference among schools. In the future, long-term research to find how the new learning medium affects knowledge retention will support the advantage for life-long learning.

    Objectives To investigate the effectiveness of different applications of mentoring in an older adult exercise program, this study compared the physical fitness scores, the retention and participation rates of older adults trained by student mentors, peer mentors, peer mentors working independently of the researchers, and a non-exercising control group. Methods 106 older adults were recruited and assigned to one of the groups using quasi-randomization. All three experimental groups completed a 14-week intervention. Pre- and post-training assessments of fitness were completed, and retention and participation rates were compared. Results High retention and participation rates, as well as significant improvements in fitness scores from baseline to post-test were observed in all three mentored groups. While the control group showed improvement only in one fitness test, subjects in the mentored groups improved similarly in all measures, regardless of the type of mentoring received. Discussion These findings indicated effectiveness of the peer mentor model and suggested that with adequate preparation peer mentors may be capable of guiding older adult participants effectively without assistance from professional staff.

    2013-03-01

    Full Text Available This study used functional magnetic resonance imaging (fMRI to examine the influence of a 9-month physical activity program on task-evoked brain activation during childhood. The results demonstrated that 8- to 9-year-old children who participated in 60+ minutes of physical activity, 5 days per week, for 9 months, showed decreases in fMRI brain activation in the right anterior prefrontal cortex coupled with within-group improvements in performance on a task of attentional and interference control. Children assigned to a wait list control group did not show changes in brain function. Furthermore, at post-test, children in the physical activity group showed similar anterior frontal brain patterns and incongruent accuracy rates to a group of college-aged young adults. Children in the wait list control group still differed from the young adults in terms of anterior prefrontal activation and performance at post-test. There were no significant changes in fMRI activation in the anterior cingulate cortex for either group. These results suggest that physical activity during childhood may enhance specific elements of prefrontal cortex function involved in cognitive control.

    Objective: To compare intercostal nerve block before and after rib harvest in terms of mean postoperative pain score and mean postoperative tramadol usage. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Plastic Surgery, Mayo Hospital, KEMU, Lahore, from January 2011 to July 2012. Methodology: Patients (n = 120) of either gender with ASA class-I and II requiring autogenous costal cartilage graft were inducted. Patients having history of local anaesthetic hypersensitivity and age 60 years were excluded. Subjects were randomly assigned to pre-rib harvest (group-1) and post-rib harvest (group-2). Local anaesthetic mixture was prepared by adding 10 milliliters 2% lidocaine to 10 milliliters 0.5% bupivacaine to obtain a total 20 ml solution. Group-1 received local anaesthetic infiltration along the proposed incision lines and intercostals block before the rib harvest. Group-2 received the infiltration and block after rib harvest. Postoperative consumption of tramadol and pain scores were measured at 6 and 12 hours postoperatively using VAS. Results: Mean age was 31.43 A +- 10.78 years. The mean pain scores at 6 hours postoperatively were 1.033 A +- 0.609 and 2.4667 A +- 0.812 in pre-rib harvest and post-rib harvest groups respectively (p < 0.0001). The mean pain scores at 12 hours postoperatively were 1.45 A +- 0.565 and 3.65 A +- 0.633 in pre-rib harvest and post-rib harvest groups respectively (p < 0.0001). The mean tramadol used postoperatively in first 24 hours was 169 A +- 29.24 mg and 255 A +- 17.70 mg in prerib harvest and post-rib harvest groups respectively (p < 0.0001). Conclusion: Intercostal block administered before rib harvest as preemptive strategy result in decreased postoperative pain scores and narcotic use. (author)

    Achievement of the UNAIDS 90-90-90 targets in Sub-Sahara Africa is challenged by a weak care-cascade with poor linkage to care and retention in care. Community-based HIV testing and counselling (HTC) is widely used in African countries. However, rates of linkage to care and initiation of antiretroviral therapy (ART) in individuals who tested HIV-positive are often very low. A frequently cited reason for non-linkage to care is the time-consuming pre-ART assessment often requiring several clinic visits before ART-initiation. This two-armed open-label randomized controlled trial compares in individuals tested HIV-positive during community-based HTC the proposition of same-day community-based ART-initiation to the standard of care pre-ART assessment at the clinic. Home-based HTC campaigns will be conducted in catchment areas of six clinics in rural Lesotho. Households where at least one individual tested HIV positive will be randomized. In the standard of care group individuals receive post-test counselling and referral to the nearest clinic for pre-ART assessment and counselling. Once they have started ART the follow-up schedule foresees monthly clinic visits. Individuals randomized to the intervention group receive on the spot point-of-care pre-ART assessment and adherence counselling with the proposition to start ART that same day. Once they have started ART, follow-up clinic visits will be less frequent. First primary outcome is linkage to care (individual presents at the clinic at least once within 3 months after the HIV test). The second primary outcome is viral suppression 12 months after enrolment in the study. We plan to enrol a minimum of 260 households with 1:1 allocation and parallel assignment into both arms. This trial will show if in individuals tested HIV-positive during community-based HTC campaigns the proposition of same-day ART initiation in the community, combined with less frequent follow-up visits at the clinic could be a pragmatic approach to

    Deficits in emotion perception are common in people with schizophrenia and current research has focused on improving these deficits. In our previous research, we demonstrated that directing attention to salient facial features via attention shaping can improve these deficits among inpatients. In this study, we examined the efficacy of an enhanced attention shaping program that contains 192 emotional expressions from which 25 are randomly presented for training. We extended our previous work by using repeated administrations of the shaping intervention and testing its effect in outpatients with schizophrenia and impaired controls. Fifteen participants with schizophrenia and fourteen college student controls with emotion perception deficits were randomly assigned to 1, 3 or 5 sessions of attention shaping. Participants completed 2 outcome measures of emotion perception, the FEIT and BLERT, not presented during the training, and underwent eye tracking at pre and post-tests. All conditions and groups improved, but the largest improvements on the BLERT and FEIT were found for persons assigned to the 5 session condition. Performance on the shaping program was positively correlated with the two outcome measures of emotion perception. There was less support for changes in visual scanning of faces as there was a relative reduction in total scanning time from pre-test to post-test. Results are interpreted in terms of the efficacy of attention shaping as a means to improve emotion perception deficits. Copyright © 2010 Elsevier B.V. All rights reserved.

    Full Text Available This study was conducted to reveal what Memrise, an online vocabulary study tool, can offer to upper-intermediate EFL learners compared to traditional vocabulary exercises in L2 vocabulary learning. Two groups of upper-intermediate learners (N=80 were randomly assigned to the experimental group and the control group and were given the Vocabulary Knowledge Scale, VKS for short, as the pre-test and post-test. The participants in both groups were exposed to the target vocabulary items in the same reading text. While those in the experimental group created list of target vocabulary items collaboratively in Memrise and then studied the sets individually, the learners in the control group did traditional vocabulary exercises. The results of the post-tests indicated that there was a significant difference between the control group and the experimental group in favor of the experimental group. The researchers discuss possible pedagogical implications of this significant finding for EFL vocabulary instruction.

    Non-pharmacological means are being developed to enhance cognitive abilities in drug abusers. This study evaluated virtual reality (VR) as an intervention tool for enhancing cognitive and vocational outcomes in 90 young ketamine users (KU) randomly assigned to a treatment group (virtual reality group, VRG; tutor-administered group, TAG) or wait-listed control group (CG). Two training programmes with similar content but different delivery modes (VR-based and manual-based) were applied using a virtual boutique as a training scenario. Outcome assessments comprised the Digit Vigilance Test, Rivermead Behavioural Memory Test, Wisconsin Cart Sorting Test, work-site test and self-efficacy pre- and post-test and during 3- and 6-month follow-ups. The VRG exhibited significant improvements in attention and improvements in memory that were maintained after 3 months. Both the VRG and TAG exhibited significantly improved vocational skills after training which were maintained during follow-up, and improved self-efficacy. VR-based cognitive training might target cognitive problems in KU.

    This study examined a gratitude intervention repeating Emmons and McCullough study (2003) in a Spanish sample, Participants were randomly assigned to one of three conditions (gratitude, hassles and any event) and kept daily records during 2 weeks of gratitude, affect, quality of relationships, physical and subjective well-being. We added design features to assess the intervention long-term impact (follow-up measures), and to improve the design control (pre-treatment measures). Following the cited authors' analysis, i.e., comparing groups only in the post-test, we replicated their results, finding differences in positive affect and gratitude between the gratitude condition and the hassles condition. However, when including both the pre and the follow-up measures in the analysis, results were replicated only partially, as the difference in gratitude disappeared. Moreover, the difference in positive affect between groups in the post-test seemed to be influenced mainly by a decrease in positive affect in the hassles group. Post-test differences between groups in positive affect disappeared in the follow-up. Gratitude interventions may have an effect on well-being, but we consider other methods to promote gratitude besides gratitude journals should be tested.

    The aim of this study was to investigate that listening to music reduces the anxiety and distress of the patients who underwent ultrasound guided core biopsy in a clinic. One hundred patients underwent Ultrasound Guided Core Biopsy of the Breast. Each patients was allocated to one of two groups with different methods whether they listened to music or not. The experimental group listening to music are 50 patients and the control group are 50 patients. The difference of VAS anxiety score of pre-test and post-test was signifcant (p<0.001). Compared by the control group, the subjective distress of the patients listening to music such as pain and tension was significant (p<0.001) but nausea and dyspnea was not significant. The objective distress of the patients listening to music was statistically significant (p<0.001). The Differances of systolic blood pressure, diastolic blood pressure, pulse between pre-test and post-test were not signifcant. The results suggest that listening to music reduces the anxiety and distress of the patients who underwent ultrasound guided core biopsy in a clinic.

    A mixed methods study was used to transcend the traditional pre-, post-test approach of citizen science evaluative research by integrating adults' test scores with their perceptions. We assessed how contributory entomology citizen science affects participants' science self-efficacy, self-efficacy for environmental action, nature relatedness and attitude towards insects. Pre- and post-test score analyses from citizen scientists ( n = 28) and a control group ( n = 72) were coupled with interviews ( n = 11) about science experiences and entomological interactions during participation. Considering quantitative data alone, no statistically significant changes were evident in adults following participation in citizen science when compared to the control group. Citizen scientists' pre-test scores were significantly higher than the control group for self-efficacy for environmental action, nature relatedness and attitude towards insects. Interview data reveal a notable discrepancy between measured and perceived changes. In general, citizen scientists had an existing, long-term affinity for the natural world and perceived increases in their science self-efficacy, self-efficacy for environmental action, nature relatedness and attitude towards insects. Perceived influences may act independently of test scores. Scale instruments may not show impacts with variances in individual's prior knowledge and experiences. The value of mixed methods on citizen science program evaluation is discussed.

    This study aimed to determine the effects of a plant cultivation-based horticultural therapy program for elderly people with mental health problems. Pre- and post-test design with experimental and control groups. Twenty-eight elderly Korean people with mental health problems participated from April to June 2017 at a farm located in Suwon, South Korea. The participants were randomly assigned to either the control (n = 14) or horticultural therapy group (n = 14); the latter participated in once-weekly sessions of a previously designed 10-session horticultural therapy program. The pre-test occurred 1 week before starting the horticultural therapy program. The post-test was completed within 1 week after finishing the final program session. Cortisol levels were measured in saliva samples collected from both groups. The Senior Fitness Test was used to assess physical functional ability in both groups. In the horticultural therapy group, the cortisol levels decreased significantly from before to after the horticultural therapy program, and the post-test scores for six subtests of the Senior Fitness Test improved significantly. No significant improvements were seen in either measure in the control group. This study demonstrates the potential ability of horticultural therapy to improve the stress levels and physical functional abilities of elderly people with mental health problems. In future studies, it would be interesting to verify the long-term effects of this horticultural therapy program and to compare its effects with regard to sex, age, and various mental symptoms.

    Sense of coherence (SOC) and mindfulness (MI) are believed to promote the health and well-being of individuals and organisations. The aim of this longitudinal study was to contribute to the literature on the development of SOC through training and interventions and thereby explore the development of these constructs in a group of senior professionals in the German Catholic Church. A sample of eight participants voluntarily enrolled for a 12-day training programme spread over a period of nine months to develop intercultural and inter-religious competencies, SOC and MI. Quantitative scores of the pre- and post-test SOC and MI questionnaires were qualitatively analysed. Results indicate that the majority of participants scored lower in the post-test on SOC and slightly higher in MI. The discussion explores the pitfalls in the development of these constructs in the study's participants and highlights the implications for theory and practice. Practical training implications for developing SOC and MI are offered.

    It is expected that nursing education improves abilities of students in solving problems, decision making and critical thinking in different circumstances. This study was performed to analyse the effects of care plans prepared using concept maps on the critical thinking dispositions of students. An experimental group and a control group were made up of a total of 80 freshman and sophomore students from the nursing department of a health school. The study used a pre-test post-test control group design. The critical thinking dispositions of the groups were measured using the California Critical Thinking Disposition Inventory. In addition, the care plans prepared by the experimental group students were evaluated using the criteria for evaluating care plans with concept maps. T-test was used in analysing the data. The results showed that there were no statistically significant differences in the total and sub-scale pre-test scores between the experimental group and control group students. There were also significant differences in the total and sub-scale post-test scores between the experimental group and control group students. There were significant differences between concept map care plan evaluation criteria mean scores of the experimental students. In the light of these findings, it could be argued that the concept mapping strategy improves critical thinking skills of students. © 2012 Blackwell Publishing Asia Pty Ltd.

    Ethics education is a critical component of training rehabilitation practitioners. There is a need for capacity-building among ethics educators regarding facilitating ethical decision-making among students. The purpose of this study was to evaluate the utility of an on-line ethics education module for occupational therapy clinician-educators (problem-based learning tutors/clinical placement preceptors/evidence-based practice facilitators). The Knowledge-to-Action Process informed development and evaluation of the module. Clinician-educators (n = 33) viewed the module and reported on its impact on knowledge and facilitation practices via pre, post, and follow-up questionnaires. Pre- and post-test data indicated improvement in self-reported ethics knowledge (t = 8.275, p ethics education module for clinician-educators. Future recommendations include broader consideration of context, adding supplemental knowledge translation components, and further research exploring outcomes with larger samples, longer follow-up and randomized trial methodology. Implications for Rehabilitation The on-line ethics module has potential to improve rehabilitation practice by addressing the noted gap in knowledge among clinician-educators. Viewing an on-line module regarding approaches to ethics education may not be sufficient to change clinician-educators' teaching practices. More time and opportunities to discuss ethics with student occupational therapists may be required to effect practice change among clinician-educators. Developing ethics education tools for clinician-educators requires ongoing and iterative input from knowledge users to optimize translation of ideas to practice.

    Research suggests that music is beneficial in teaching both social and academic skills to young children. The purpose of this study was to examine the effects of a music therapy program designed to teach reading skills versus the "Between the Lions" television program on the early literacy behaviors of Kindergarten children from a low socioeconomic background. Subjects (n = 86) were children, aged 5-7 years, enrolled in one of four different Kindergarten classes at a public elementary school in Northwest Florida. Each class was assigned one of four treatment conditions: Music/Video (sequential presentation of each condition), Music-Only, Video-Only, and no contact Control group. Growth in early literacy skills was measured using the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) and 3 subtests of the Test of Early reading Ability-3rd edition (TERA-3). Teachers' perceptions of classroom literacy behaviors were measured using a pre and poststudy survey. This study also compared on- and off-task behavior of students during video versus music conditions. Results of the 7 subtests measuring early literacy were varied. The Music/Video and Music-Only groups achieved the highest increases in mean scores from pre to posttest on 4 of the 7 subtests. Students in the Video-Only group scored significantly better on the phonemic segmentation portion of the DIBELS than peers in the Music/Video condition. Furthermore, strong correlations were found between the Letter Naming, Initial Sounds Fluency tests, and total raw score of the TERA-3 tests for both pre and posttesting. Additionally, graphic analysis of mean off-task behavior per session indicated that students were more off-task during both video conditions (video alone and video portion of Music/Video condition) than during the music conditions. Off-task behavior was consistently lower during music sessions for the duration of the study. This study confirmed that music increases the on-task behavior of students

    Full Text Available Background: Propofol is one of the widely used intravenous (i.v. anaesthetics, although pain on injection still remains a considerable concern for the anaesthesiologists. A number of techniques has been tried to minimize propofol-induced pain with variable results. Recently, a 5-HT 3 antagonist, ondansetron pre-treatment, has been shown to reduce propofol-induced pain. The aim of our randomized, placebo-controlled, double-blinded study was to determine whether pre-treatment with intravenous granisetron, which is routinely used in our practice for prophylaxis of post-operative nausea and vomiting, would reduce propofol-induced pain. Methods: Eighty-two women, aged 18-50 years, American society of Anaesthesiologist grading (ASA I-II, scheduled for various surgeries under general anaesthesia were randomly assigned to one of the two groups. One group received 2 mL 0.9% sodium chloride while the other group received 2 mL granisetron (1 mg/mL, and were accompanied by manual venous occlusion for 1 min. Then, 2 mL propofol was injected through the same cannula. Patients were asked by a blinded investigator to score the pain on injection of propofol with a four-point scale: 0=no pain, 1=mild pain, 2=moderate pain, 3=severe pain. Results: Twenty-four patients (60% complained of pain in the group pre-treated with normal saline as compared with six (15% in the group pre-treated with granisetron. Pain was reduced significantly in the granisetron group (P<0.05. Severity of pain was also lesser in the granisetron group compared with the placebo group (2.5% vs. 37.5%. Conclusion: We conclude that pre-treatment with granisetron along with venous occlusion for 1 min for prevention of propofol-induced pain was highly successful.

    Adolescence represents a critical period for the development of overweight that tracks into adulthood. This risk is significantly heightened for adolescents that become pregnant, many of whom experience postpartum weight retention. The aim of this study was to evaluate Balance Adolescent Lifestyle Activities and Nutrition Choices for Energy (BALANCE), a multicomponent obesity prevention intervention targeting postpartum adolescents participating in a national home visiting child development-parent education program. A group randomized, nested cohort design was used with 1325 adolescents, 694 intervention and 490 control, (mean age = 17.8 years, 52 % underrepresented minorities) located across 30 states. Participatory methods were used to integrate lifestyle behavior change strategies within standard parent education practice. Content targeted replacement of high-risk obesogenic patterns (e.g. sweetened drink and high fat snack consumption, sedentary activity) with positive behaviors (e.g. water intake, fruit and vegetables, increased walking). Parent educators delivered BALANCE through home visits, school based classroom-group meetings, and website activities. Control adolescents received standard child development information. Phase I included baseline to posttest (12 months); Phase II included baseline to follow-up (24 months). When compared to the control group, BALANCE adolescents who were ≥12 weeks postpartum were 89 % more likely (p = 0.02) to maintain a normal BMI or improve an overweight/obese BMI by 12 months; this change was not sustained at 24 months. When compared to the control group, BALANCE adolescents significantly improved fruit and vegetable intake (p = .03). In stratified analyses, water intake improved among younger BALANCE teens (p = .001) and overweight/obese BALANCE teens (p = .05) when compared to control counterparts. There were no significant differences between groups in sweetened drink and snack consumption

    Early adolescent girls' rates of drug use have matched, and in some instances, surpassed boys' rates. Though girls and boys share risk factors for drug use, girls also have gender-specific risks. Tailored interventions to prevent girls' drug use are warranted. This study developed and tested a web-based, drug abuse prevention program for adolescent girls. The nationwide sample of 13- and 14-year-old girls (N = 788) was recruited via Facebook ads. Enrolled girls were randomly assigned to the intervention or control condition. All girls completed pretest measures online. Following pretest, intervention girls interacted with the 9-session, gender-specific prevention program online. The program aimed to reduce girls' drug use and associated risk factors by improving their cognitive and behavioral skills around such areas as coping with stress, managing mood, maintaining a healthy body image, and refusing drug use offers. Girls in both conditions again completed measures at posttest and 1-year follow-up. At posttest, and compared to girls in the control condition, girls who received the intervention smoked fewer cigarettes and reported higher self-esteem, goal setting, media literacy, and self-efficacy. At 1-year follow-up, and compared to girls in the control condition, girls who received the intervention reported engaging in less binge drinking and cigarette smoking; girls assigned to the intervention condition also had higher alcohol, cigarette, and marijuana refusal skills, coping skills, and media literacy and lower rates of peer drug use. This study's findings support the use of tailored, online drug abuse prevention programming for early adolescent girls.

    Music performance anxiety affects numerous musicians, with many of them reporting impairment of performance due to this problem. This exploratory study investigated the effects of virtual reality exposure training on students with music performance anxiety. Seventeen music students were randomly assigned to a control group (n=8) or a virtual training group (n=9). Participants were asked to play a musical piece by memory in two separate recitals within a 3-week interval. Anxiety was then measured with the Personal Report of Confidence as a Performer Scale and the S-Anxiety scale from the State-Trait Anxiety Inventory (STAI-Y). Between pre- and post-tests, the virtual training group took part in virtual reality exposure training consisting of six 1-hour long sessions of virtual exposure. The results indicate a significant decrease in performance anxiety for musicians in the treatment group for those with a high level of state anxiety, for those with a high level of trait anxiety, for women, and for musicians with high immersive tendencies. Finally, between the pre- and post-tests, we observed a significant increase in performance quality for the experimental group, but not for the control group.

    The aim of this study was to investigate the influence of a ballroom dancing program on the postural balance of institutionalized elderly residents. The sample consisted of 59 sedentary elderly residents of long-stay institutions who were randomly assigned to a ballroom dancing experimental group (EG, n=30) or a control group (CG, n=29). The ballroom dancing program consisted of three 50-min sessions each week on alternate days over a 12-week period. The dances included the foxtrot, waltz, rumba, swing, samba and bolero. The medical records of the subjects were reviewed to determine the number of falls they experienced in the three months prior to the intervention. Postural static balance was assessed using a Lizard (Med. EU., Italy, 2010) stabilometric and posturometric platform. Only patients in the EG lost a significant amount of weight (Δ=-2.85 kg) when comparing the pre- and post-test postural balance assessments. The intergroup comparison revealed a reduced lower limb weight distribution difference in the EG post-test compared to the CG post-test (p=0.012). In the intragroup comparison, the EG patients experienced significantly fewer falls post-test relative to pre-test (pfalls in the EG post-test compared to the CG post-test (pbalance via a ballroom dancing program. This activity improved balance and reduced the number of falls in this elderly population. Copyright © 2014. Published by Elsevier Ireland Ltd.

    2015-01-01

    National Tobacco Control Programme was launched in India in year 2007-08. It was realized that community health workers can play an important role of agents for positive change to bring down the tobacco morbidity and mortality in the country. Keeping this in view, a health worker guide was developed by the Government of India, Ministry of Health and Family Welfare (GOI) in collaboration with The Union South-East Asia (The Union) in the year 2010. The guide provides the information needed by the most basic level of health workers to effectively address the problem of tobacco use in the community. A modular training was conducted in two jurisdictions in India (namely, Chandigarh and Hamirpur (Himachal Pradesh)) to assess the usefulness of the guide as training material for community health workers in undertaking tobacco control activities at community and village levels. A total of 271 participants were trained, which included 133 from Chandigarh and 138 from Hamirpur. The pre and post-training assessment of knowledge of health worker was done. There was marked increase in post-test scores as compared to the pretest scores. The health workers scoring more than 60% increased from 40% in the pretest to over 80% in the post-test. Only three workers had a post-test score of less than 30% against 54 workers in the pretest. The understanding on tobacco control had increased significantly after the training in each group. It is strongly recommended that such training should be replicated to all community health workers across all the states in India.

    Malaria is endemic in Nigeria, with significant records of mortality and morbidity. Adequate community involvement is central to a successful implementation of malaria control programs. This study assessed the effects of a training programme on knowledge of malaria prevention and control among community role model care givers. A descriptive cross sectional study of a pre-and post-test design method was conducted among 400 eligible community members in Osun State. Training was given in the form of organized lectures, health education and practical demonstration sessions. Scores of pre-test and post-test conducted after four months interval were compared. Multistage sampling method was adopted in selecting study participants, while data was analyzed using the SPSS software version 17.0. Mean age was 43.8 (±1.4) years. Average knowledge score of cause, transmission, risk factors and consequences, awareness of common symptoms and preventive practices improved during post-training test when compared with pr-training test. The overall descriptive mean knowledge score in pre-test and post-test were 2.1 and 3.5 respectively out of an average maximum score of 5.0, giving an increment of 66.7%. Role model care givers with formal education were twice and three times more likely to know about disease 'transmission' (OR 1.9, 95%CI 0.11-0.19, p=0.002) and 'consequences' (OR 2.9, 95%CI 0.25-0.65, p=0.040) respectively compared to those without formal education. Training on malaria improved the knowledge of malaria prevention and control among role model community care givers towards a successful implementation of malaria control programmes.

    The purpose of this study was to investigate the impact of the Iowa Children's Water Festival on selected Iowa fifth graders' attitudes toward the environment. The researcher evaluated fifth graders' attitudinal/behavioral changes toward the environment before and after their participation in the 2003 Iowa Children's Water Festival. Of the total number of 38 schools participating in the ICWF, 12 schools (participants n = 274) that completed both the pre/posttest Children's Attitudes Toward the Environment Scale (CATES) were assigned to the experimental group. Three of 12 schools (participants n = 42) that did not participate in the ICWF and returned the pretest CATES were assigned to the control group. Participants (n = 274) were compared to non-participants (n = 42) to determine whether there were substantial differences in the general attitudes toward the environment based on several factors (e.g., pre/posttest, gender, locale, and school type). A one-page survey instrument (CATES) was administered two times (pre/posttest) in a three week period for both groups. Descriptive, inferential statistics were used to investigate whether children who participated in the ICWF improved their attitudes toward the environment compared to children who did not participate in the educational event. An analysis of covariance was employed to test the hypothesis. ANCOVA (regression fashion) indicated that there was no difference in posttest CATES scores between those children who attended the ICWF compared to those who did not attend. To explore the long-term impacts of the participants' attitudinal/behavioral changes, a qualitative follow-up interview was conducted six months after the children's attendance at the 2003 ICWF. Six students from a central, rural elementary school that completed both the pre/posttest CATES were interviewed employing open-ended interview questions. The results suggested that not only are such factors as knowledge gain and behavioral changes critical

    Full Text Available This paper is a quasi-experimental research. It was aimed to investigate the significant difference on vocabulary achievement between two groups who were taught by using Mind Mapping strategy and those who were taught by using Making Notes strategy. The subjects of this study were the students in class 5B and 5D of An-Nissa Islamic Billingual Elementary School of Semarang. 5B was the experimental group and 5D was the control group. In this research, I gave them a pre-test, treatments, and a post-test. I used the same instrument in the pre-test for both groups. They were asked to answer some questions of vocabulary test. The treatments were given in three meetings. The treatment used in the experimental group was Mind Mapping strategy, while the treatment in the control group was Making Notes strategy. The post-test in both groups were conducted after the treatments by using the same instrument as the pre-test but the position of question numbers were reshuffled. The result of the test was analyzed by using t-test formula to know the difference of the students‘ achievement in vocabulary between two groups. The analysis of the test result showed that the experimental group got better score than the control group. That calculation revealed that the hypothesis 1 (Ha was accepted and the hypothesis 2 (Ho was rejected. Based on the proven hypotheses, I concluded that Mind Mapping strategy is more effective to be implemented in teaching vocabulary than Making Notes strategy.

    Preparing nursing students for the knowledge and skills required for the administration and monitoring of blood components is crucial for entry into clinical practice. Serious games create opportunities to develop this competency, which can be used as a self-directed learning strategy to complement existing didactic learning and simulation-based strategies. To describe the development and evaluation of a serious game to improve nursing students' knowledge, confidence, and performance in blood transfusion. An experiential gaming model was applied to guide the design of the serious game environment. A clustered, randomized controlled trial was conducted with 103 second-year undergraduate nursing students who were randomized into control or experimental groups. After a baseline evaluation of the participants' knowledge and confidence on blood transfusion procedure, the experimental group undertook a blood transfusion serious game and completed a questionnaire to evaluate their learning experience. All participants' clinical performances were evaluated in a simulated environment. The post-test knowledge and confidence mean scores of the experimental group improved significantly (pgame intervention compared to pre-test mean scores and to post-test mean scores of the control group (pgame positively. The study provided evidence on the effectiveness of a serious game in improving the knowledge and confidence of nursing students on blood transfusion practice. The features of this serious game could be further developed to incorporate additional scenarios with repetitive exercises and feedback to enhance the impact on clinical performance. Given the flexibility, practicality, and scalability of such a game, they can serve as a promising approach to optimize learning when blended with high-fidelity simulation. Copyright © 2017.

    Full Text Available Background and Aim: Statistics show that 30% to 40 % of  opium addicted fathers’ children are prone to substance abuse in the future. The present study aimed at assessing the effectiveness of cognitive therapy approach  to attitude changing of adolescents with substance dependent fathers. Materials and Methods:  In this controlled. field-trail randomized study. .data collection tool was “attitude to addiction questionnaire”. The study population was all male students in the first grade of high school in Maneh - Samalghan city. . Six sessions of group cognitive therapy based on the effectiveness of drug side-effects in drug-addicted fathers’ adolescent children’s attitude were held. The above-mentioned questionnaire was filled out before and after intervention. The obtained data  was fed into SPSS software (V: 16 using. Independent t-test .and paired t-test were used for analysis and P<0.05 was taken as the significant level. Results:  There were no significant differences between the two groups in pre-test regarding their attitude about drug abuse (P=.20%. Mean score variance from pre-test to post-test in the intervention group decreased, but in the control group, it showed a slight increase. This means that the intervention reduced the positive attitude towards drugs, but the changes were not statistically significant (p=0.57. Besides, among ten factors decisive in an individual’s attitude about addiction, only group cognitive therapy  was able  to decrease mean points of an individual’s attitude about drug abuse .. Significantly (P = 0.04. Conclusion: It was found that group cognitive therapy education about opium  addict complicationsdidn`t have a significant effect on the attitude of the students with addicted fathers. Thus, a change of adolescents’ attitude requires more research.

    Regulating emotions, refraining from impulsive, maladaptive behavior, and communicating effectively are considered primary treatment needs among jail inmates. Dialectical behavior therapy (DBT; Linehan, 1993a) skills address these deficits and have been implemented in long-term correctional settings, but have yet to be adapted for general population inmates in short-term jail settings. This study assessed the feasibility and acceptability of a DBT skills group in a jail setting, as well as its utility in improving coping skills and emotional/behavioral dysregulation. Male jail inmates participated in an 8-week DBT skills group and completed pre- and posttest assessments of coping skills, emotional/behavioral dysregulation, and measures of treatment acceptability. Out of 27 who started therapy, 16 completed it, primarily due to involuntary attrition such as transfer to another correctional facility. Although several logistical issues arose during this pilot study, preliminary results suggest that a brief DBT skills group is feasible and acceptable in a jail setting, and may improve coping skills and reduce externalization of blame among general population jail inmates. This study lays the groundwork for larger, controlled trials of abbreviated DBT skills groups for general population inmates in short-term jail settings.

  3. Grouped to Achieve: Are There Benefits to Assigning Students to Heterogeneous Cooperative Learning Groups Based on Pre-Test Scores?

    Science.gov (United States)

    Werth, Arman Karl

    Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

    2014-02-01

    Concept mapping, as a teaching strategy, has been shown to promote critical thinking and problem solving in educational settings. Dental clinicians must distinguish between critical and irrelevant characteristics in the delivery of care, thus necessitating reasoning skills to do so. One of the aims of the American Dental Education Association Commission on Change and Innovation (ADEA-CCI) is to identify deficiencies in curriculum which were meant to improve critical thinking and problem solving skills necessary in clinical practice. The purpose of this study was to compare 2 teaching strategies, traditional lecture and lecture supported by concept mapping exercises within collaborative working groups, to determine if there is a beneficial effect on meaningful learning. For this pilot study, the study population consisted of students from 2 geographically separated associate level dental hygiene programs in the southeastern U.S. A quasi-experimental control group pre- and post-test design was used. The degree of meaningful learning achieved by both programs was assessed by comparing pre- and post-test results. Both programs experienced a significant degree of meaningful learning from pre- to post-test. However, there was no statistically significant difference between the programs on the post-test. These results were in direct contrast to research in other disciplines on concept mapping and its effect on promoting meaningful learning. Further investigation into the study's outcome was obtained through a follow-up focus group. In spite of careful attention to methodology in the development of this research project, the focus group illuminated methodological failings that potentially impacted the outcome of the study. Recommendations are underscored for future conduct of educational research of this kind.

    We report on an experiment comparing examinations of concepts using slightly modified peer instruction (MPI) interventions with a conceptual conflict strategy based on collaborative groups (CG). Four interventions were utilized in two sections of an introductory physics course for science students. Both instructors and strategies were alternated in the two classes so that instructor dependence could be factored out and so that each class could serve as both an experimental and a control group. The gain on the Force Concept Inventory (FCI) used as a pre- and post-test is essentially the same in both classes. The instructors were experienced in use of MPI, but this was the first time that these instructors had used a collaborative group activity in their classes and only used it for the two interventions in each class described in this paper. CG appears to be more effective as a teaching method than PI. It also should be noted that the effectiveness of both teaching methods seems to be instructor independent as long as the instructors followed the same protocol. (author)

    Studies investigating the effectiveness of delirium e-learning tools in clinical practice are scarce. The aim of this study is to determine the effect of a delirium e-learning tool on healthcare workers' delirium recognition, delirium knowledge and care strain in delirium. A pilot pre-posttest study in a convenience sample of 59 healthcare workers recruited from medical, surgical, geronto-psychiatric and rehabilitation units of a university hospital. The intervention consisted of a live information session on how to use the e-learning tool and, a 2-month self-active learning program. The tool included 11 e-modules integrating knowledge and skill development in prevention, detection and management of delirium. Case vignettes, the Delirium Knowledge Questionnaire, and the Strain of Care for Delirium Index were used to measure delirium recognition, delirium knowledge and experienced care strain in delirium respectively. Subgroup analyses were performed for healthcare workers completing 0 to 6 versus 7 to 11 modules. The delirium recognition score improved significantly (mean 3.1 ± SD 0.9 versus 2.7 ± 1.1; P = 0.04), and more healthcare workers identified hypoactive (P = 0.04) and hyperactive (P = 0.007) delirium in the posttest compared to the pretest phase. A significant difference in the change of recognition levels over time between the 0 to 6 and 7 to 11 module groups was demonstrated (P = 0.03), with an improved recognition level in the posttest phase within the 7 to 11 module group (P = 0.007). After adjustment for potential confounders, this difference in the change over time was not significant (P = 0.07) and no change in recognition levels within the 7 to 11 module group was noted (P = 0.19). The knowledge score significantly improved in the posttest compared to the pretest phase (mean 31.7 ± SD2.6 versus 28.3 ± 4.5; P e-learning tool improved healthcare workers' delirium recognition and knowledge.

Pre-operative axillary ultrasound (US) and fine needle aspiration cytology (FNAC) assessments have become routine practice in many breast units, although the evidence base is still gathering. This study assessed the clinical utility of US+/-FNAC in patient selection for either axillary node clearance (ANC) or sentinel lymph node biopsy (SLNB) in patients undergoing surgery for operable breast cancer. Over a two-year period, 348 patients with a clinically negative axilla underwent axillary US. 67 patients with suspicious nodes on US also underwent FNAC. The sensitivity and specificity of axillary investigations to determine nodal involvement were 56% (confidence interval: 47-64%) and 90% (84-93%) for US alone, and 76% (61-87%) and 100% (65-100%) for FNAC combined with US, respectively. With a positive US, the post-test probability was 78%. A negative US carried a post-test probability of 25%. When FNAC was positive, the post-test probability was greater than unity. A negative FNAC yielded a post-test probability of 52%. All patients with positive FNAC and most patients with suspicious US were listed for axillary node clearance (ANC) after consideration at the multi-disciplinary team (MDT) meeting. With pre-operative axillary US+/-FNAC, 20% of patients were saved a potential second axillary procedure, facilitating a reduction in the overall re-operation rate to 12%. In this study, a positive pre-operative US+/-FNAC directs patients towards ANC. When the result is negative, other clinico-pathological factors need to be taken into account in the selection of the appropriate axillary procedure. Copyright © 2011 Elsevier Ltd.

    The profound impact of empathy training on quality nursing care has been recognized. Studies have shown that there has been little improvement in nurses' communication skills, and that they should work to enhance this area. Relevant training will lead to an improvement in nurses' empathic skills, which in turn, will enable them to understand their patients better, establish positive interpersonal relationships with them, and boost their professional satisfaction. To reveal the effect of empathy training on the empathic skills of nurses. This study was conducted as an experimental design. The research sample consisted of 48 nurses working at the pediatric clinics of Farabi hospital of Karadeniz Technical University in Turkey (N = 83). Two groups, an experimental group (group 1) and a control group (group 2) were determined after questionnaires were supplied to all nurses in the study sample. At first, it was intended to select these groups using a random method. However, since this may have meant that the experimental and control groups were formed from nurses working in the same service, the two groups were selected from different services to avoid possible interaction between them. The nurses in the Group 1 were provided with empathy training through group and creative drama techniques. Pre-tests and post-tests were conducted on both groups. Data was collected via a questionnaire designed around the topic "empathic skill scale-ESS", developed by Dokmen. The Kolmogorov Smirnov test was employed to assess whether the measurable data was suitable for normal distribution. Data was presented as numbers and percentage distributions, as mean ± standard deviation and Chi-square, and as student t tests and paired t tests. The level of significance was accepted as P nurses in the experimental group had a mean score of 146.7 ± 38.8 and 169.5 ± 22.1 in the ESS pre-test and post-test, respectively. Although the nurses in the control group had a pre-test mean score of 133

    This study aimed to assess the Parent-Adolescent Communication Toolkit, an online intervention designed to help improve parent communication with their adolescents. Participant preferences for two module delivery systems (sequential and unrestricted module access) were identified. Usability assessment of the PACT intervention was completed using pre-test and posttest comparisons. Usability data, including participant completion and satisfaction ratings were examined. Parents ( N  =   18) of adolescents were randomized to a sequential or unrestricted chapter access group. Parent participants completed pre-test measures, the PACT intervention and posttest measures. Participants provided feedback for the intervention to improve modules and provided usability ratings. Adolescent pre- and posttest ratings were evaluated. Usability ratings were high and parent feedback was positive. The sequential module access groups rated the intervention content higher and completed more content than the unrestricted chapter access group, indicating support for the sequential access design. Parent mean posttest communication scores were significantly higher ( p  Communication Toolkit has potential to improve parent-adolescent communication but further effectiveness assessment is required.

    Background and aims The fast development of e-learning and social forums demands us to update our understanding of e-learning and peer learning. We aimed to investigate if higher, pre-defined levels of e-learning or social interaction in web forums improved students' learning ability. Methods One hundred and twenty Danish medical students were randomized to six groups all with 20 students (eCases level 1, eCases level 2, eCases level 2+, eTextbook level 1, eTextbook level 2, and eTextbook level 2+). All students participated in a pre-test, Group 1 participated in an interactive case-based e-learning program, while Group 2 was presented with textbook material electronically. The 2+ groups were able to discuss the material between themselves in a web forum. The subject was head injury and associated treatment and observation guidelines in the emergency room. Following the e-learning, all students completed a post-test. Pre- and post-tests both consisted of 25 questions randomly chosen from a pool of 50 different questions. Results All students concluded the study with comparable pre-test results. Students at Level 2 (in both groups) improved statistically significant compared to students at level 1 (p>0.05). There was no statistically significant difference between level 2 and level 2+. However, level 2+ was associated with statistically significant greater student's satisfaction than the rest of the students (p>0.05). Conclusions This study applies a new way of comparing different types of e-learning using a pre-defined level division and the possibility of peer learning. Our findings show that higher levels of e-learning does in fact provide better results when compared with the same type of e-learning at lower levels. While social interaction in web forums increase student satisfaction, learning ability does not seem to change. Both findings are relevant when designing new e-learning materials.

    Cognitive impairment occurs in 40%-65% of patients with multiple sclerosis (MS). Several techniques for cognitive rehabilitation (CR) in these patients have been evaluated; however, the results have been controversial. In this study, we investigated the efficacy of group compensatory CR in patients with MS-related cognitive impairment. Thirty-four female patients with diagnosed relapsing-remitting MS and evidence of impaired cognitive function were included and randomized to intervention (n = 17) and control (n = 17) groups. CR intervention consisted of eight 2-hour sessions of comprehensive group CR over a 4-week period that focused on improvement of memory, attention, and executive function. As placebo, the control group received the same number of non-therapeutic group sessions. Assessment of cognitive function was performed before intervention (pretest), at the end of intervention (post-test), and 3 months later (follow-up). The study population included 34 patients with a mean age of 35.5 years. Statistical comparison of memory assessments at 3-month follow-up showed significantly higher scores in the CR group than in the control group (93.33 vs 86.40 for Addenbrooke's Cognitive Examination test and 16.58 vs 12.00 for visual memory, 19.32 vs 14.05 for verbal memory, and 51.28 vs 44.41 for general scores on the Memory Functioning Questionnaire test, respectively). Wisconsin card sorting test score comparison showed significantly lower total time consumption in the CR group than in the control group (308.1 vs 340.8 seconds, respectively). Behavior rating inventory of executive function-adult scores in all four subtests were significantly higher in the CR group than in the control group (40.25 vs 55.4 for behavioral regulation index, 51.16 vs 68.6 for metacognition index, and 97.41 vs 124.00 for global executive composite, respectively). Attention was the only domain in which we did not observe any significant variation between groups in terms of post-test

    Three-dimensional (3D) printing is an emerging technology capable of readily producing accurate anatomical models, however, evidence for the use of 3D prints in medical education remains limited. A study was performed to assess their effectiveness against cadaveric materials for learning external cardiac anatomy. A double blind randomized controlled trial was undertaken on undergraduate medical students without prior formal cardiac anatomy teaching. Following a pre-test examining baseline external cardiac anatomy knowledge, participants were randomly assigned to three groups who underwent self-directed learning sessions using either cadaveric materials, 3D prints, or a combination of cadaveric materials/3D prints (combined materials). Participants were then subjected to a post-test written by a third party. Fifty-two participants completed the trial; 18 using cadaveric materials, 16 using 3D models, and 18 using combined materials. Age and time since completion of high school were equally distributed between groups. Pre-test scores were not significantly different (P = 0.231), however, post-test scores were significantly higher for 3D prints group compared to the cadaveric materials or combined materials groups (mean of 60.83% vs. 44.81% and 44.62%, P = 0.010, adjusted P = 0.012). A significant improvement in test scores was detected for the 3D prints group (P = 0.003) but not for the other two groups. The finding of this pilot study suggests that use of 3D prints do not disadvantage students relative to cadaveric materials; maximally, results suggest that 3D may confer certain benefits to anatomy learning and supports their use and ongoing evaluation as supplements to cadaver-based curriculums.

    Motor practice in lucid dreams is a form of mental rehearsal where the dreamer can consciously rehearse motor skills in the dream state while being physically asleep. A previous pilot study showed that practice in lucid dreams can improve subsequent performance. This study aimed to replicate those findings with a different task (finger-tapping) and compare the effectiveness of lucid dream practice (LDP) not only to physical but also to mental practice (MP) in wakefulness. An online experiment was completed by 68 participants within four groups: LDP group, MP group, physical practice (PP) group and control (no practice) group. Pre-test was accomplished in the evening, post-test in the next morning, while the practice was done during the night. All three practice groups significantly improved their performance from pre-test to post-test, but no significant improvements were observed for the control group. Subjective sleep quality was not affected by night practice. This study thus corroborates the previous findings that practice in lucid dreams is effective in improving performance. Its effects seem to be similar to actual PP and MP in wakefulness. Future studies should establish reliable techniques for lucid dream induction and verify the effects of LDP in sleep laboratory conditions.

    We have characterized a suite of samples taken subsequent to the end of the Spent Fuel Test - Climax by petrographic and microanalytical techniques and determined their mineral assemblage, modal properties, and mineral chemistry. The samples were obtained immediately adjacent to the canister borehole at a variety of depths and positions within the canister drift, as well as radially outward from each canister hole. This method of sampling allows variations in post-test mineralogic properties to be evaluated on the basis of (1) depth along a particular canister hole and (2) position within the canister drift, with respect to the heat and radiation sources, and with respect to the pre - test samples. In no case did we find any significant correlation between the mineralogical properties and variables listed above. In short, the Spent Fuel Test - Climax has produced no identifiable mineralogical response in the Climax quartz monzonite. 12 refs., 11 figs., 5 tabs

    SAGES FUSE curriculum provides didactic knowledge on OR fire prevention. The objective of this study is to evaluate the impact of an immersive virtual reality (VR)-based OR fire training simulation system in combination with FUSE didactics. The study compared a control with a simulation group. After a pre-test questionnaire that assessed the baseline knowledge, both groups were given didactic material that consists of a 10-min presentation and reading materials about precautions and stopping an OR fire from the FUSE manual. The simulation group practiced on the OR fire simulation for one session that consisted of five trials within a week from the pre-test. One week later, both groups were reassessed using a questionnaire. A week after the post-test both groups also participated in a simulated OR fire scenario while their performance was videotaped for assessment. A total of 20 subjects (ten per group) participated in this IRB approved study. Median test scores for the control group increased from 5.5 to 9.00 (p = 0.011) and for the simulation group it increased from 5.0 to 8.5 (p = 0.005). Both groups started at the same baseline (pre-test, p = 0.529) and reached similar level in cognitive knowledge (post-test, p = 0.853). However, when tested in the mock OR fire scenario, 70% of the simulation group subjects were able to perform the correct sequence of steps in extinguishing the simulated fire whereas only 20% subjects in the control group were able to do so (p = 0.003). The simulation group was better than control group in correctly identifying the oxidizer (p = 0.03) and ignition source (p = 0.014). Interactive VR-based hands-on training was found to be a relatively inexpensive and effective mode for teaching OR fire prevention and management scenarios.

    2016-04-01

    In the latter half of the 20th century, registered nurse education moved to university degree level. As a result, there has been a reduction in access for students to clinical experience. In numerous studies, nursing graduates have reported that they do not feel prepared for practice. The importance of maximising every learning opportunity during nursing school is paramount. At Edith Cowan University, a program was initiated that allows students to become enrolled nurses at the midway point of their degree to enable them to work and therefore gain experience in the clinical practice setting during their education. This study investigated the effect of the program on the nursing students' perception of their clinical abilities and explored their ability to link theory to practice. The research design for this study was a quasi-experimental, prospective observational cohort study. The study included 39 second-year nursing students not enrolled in the program (Group 1), 45 second-year nursing students enrolled in the program (Group 2), and 28 third-year nursing students who completed the program and are working as enrolled nurses (Group 3). Participants were asked to complete a Five Dimension of Nursing Scale questionnaire. The quantitative analyses showed that students in Group 1 had statistically significant higher pre-questionnaire perceived abilities across all domains, except in two dimensions when compared to Group 2. The post-questionnaire analysis showed that Group 1 had statistically significant lower perceived abilities in four of the five dimensions compared to Group 2. Group 1 also had significantly lower abilities in all dimensions compared to Group 3. Group 3 had a significantly higher perception of their clinical abilities compared to Group 2. This study highlights the value of meaningful employment for undergraduate nursing students by providing opportunities to increase confidence in clinical abilities. Copyright © 2016 Elsevier Ltd.

    The use of standardized patients is not very common in psychiatric nursing education and there has been no study conducted in Turkey. This study evaluated the impact of using standardized patients in psychiatric cases on the levels of motivation and perceived learning of the nursing students. This manuscript addressed the quantitative aspect of a doctoral thesis study in which both quantitative and qualitative methods were used. A pre-test and post-test were employed in the quantitative analysis in a randomized and controlled study design. The motivation scores, and interim and post-test scores for perceived learning were higher in the experimental group compared to pre-test scores and the scores of the control group. The students in the experimental group reported that they felt more competent about practical training in clinical psychiatry, as well as in performing interviews with patients having mental problems, and reported less anxiety about performing an interview when compared to students in the control group. It is considered that the inclusion of standardized patient methodology in the nursing education curriculum in order to improve the knowledge level and skills of students would be beneficial in the training of mental health nurses.

    Evidence has suggested that periodontal disease is associated with an increased risk of various adverse pregnancy and birth outcomes. However, several large clinical randomized controlled trials failed to demonstrate periodontal therapy during pregnancy reduced the incidence of adverse pregnancy and birth outcomes. It has been suggested that the pre-conception period may be an optimal period for periodontal disease treatment rather than during pregnancy. To date, no randomized controlled trial (RCT) has examined if treating periodontal disease before pregnancy reduces adverse birth outcomes. This study aims to examine if the pre-conception treatment of periodontal disease will lead to improved periodontal status during late pregnancy and subsequent birth outcomes. A sample of 470 (235 in each arm of the study) pre-conception women who plan to conceive within one year and with periodontal disease will be recruited for the study. All participants will be randomly allocated to the intervention or control group. The intervention group will receive free therapy including dental scaling and root planning (the standard therapy), supragingival prophylaxis, and oral hygiene education. The control group will only receive supragingival prophylaxis and oral hygiene education. Women will be followed throughout their pregnancy and then to childbirth. The main outcomes include periodontal disease status in late pregnancy and birth outcomes measured such as mean birth weight (grams), and mean gestational age (weeks). Periodontal disease will be diagnosed through a dental examination by measuring probing depth, clinical attachment loss and percentage of bleeding on probing (BOP) between gestational age of 32 and 36 weeks. Local and systemic inflammatory mediators are also included as main outcomes. This will be the first RCT to test whether treating periodontal disease among pre-conception women reduces periodontal disease during pregnancy and prevents adverse birth outcomes. If

    In a randomised controlled trial, we investigated whether a cognitive training based on rhythm-music and music improvisation exercises had positive effects on executive functions in older participants. Thirty-five residents in a guest home with mild-moderate cognitive impairment and healthy ageing were randomly assigned to an experimental group (n = 18) featuring cognitive music training composed of 12 bi-weekly 70-min sessions, and a control group (n = 17) attended 12 bi-weekly 45-min sessions of gymnastic activities offered by the institute. A neuropsychological test battery was administered at baseline and at the end of treatment, including the Mini-Mental State Examination, verbal fluency test, Trail Making Test A, attentional matrices test and clock-drawing test. Pre-test and post-test comparison showed a significant improvement for the experimental group reflected in the Mini-Mental State Examination (F(1,33) = 13.906; p music-rhythmic exercises and music improvisation exercises is associated with improved cognitive functions in older people with mild-moderate cognitive impairment regardless of the individual's degree of cognitive reserve.

    Full Text Available Abstract Background The Internet can increase access to psychosocial care for breast cancer survivors through online support groups. This study will test a novel prosocial online group that emphasizes both opportunities for getting and giving help. Based on the helper therapy principle, it is hypothesized that the addition of structured helping opportunities and coaching on how to help others online will increase the psychological benefits of a standard online group. Methods/Design A two-armed randomized controlled trial with pretest and posttest. Non-metastatic breast cancer survivors with elevated psychological distress will be randomized to either a standard facilitated online group or to a prosocial facilitated online group, which combines online exchanges of support with structured helping opportunities (blogging, breast cancer outreach and coaching on how best to give support to others. Validated and reliable measures will be administered to women approximately one month before and after the interventions. Self-esteem, positive affect, and sense of belonging will be tested as potential mediators of the primary outcomes of depressive/anxious symptoms and sense of purpose in life. Discussion This study will test an innovative approach to maximizing the psychological benefits of cancer online support groups. The theory-based prosocial online support group intervention model is sustainable, because it can be implemented by private non-profit or other organizations, such as cancer centers, which mostly offer face-to-face support groups with limited patient reach.

    Full Text Available Eye Movement Desensitization and Reprocessing is a psychotherapeutic approach with recognized efficiency in treating post-traumatic stress disorder (PTSD, which is being used and studied in other psychiatric diagnoses partially based on adverse and traumatic life experiences. Nevertheless, there is not enough empirical evidence at the moment to support its usefulness in a diagnosis other than PTSD. It is commonly accepted that the use of EMDR in severely traumatized patients requires an extended stabilization phase. Some authors have proposed integrating both the theory of structural dissociation of the personality and the adaptive information processing model guiding EMDR therapy. One of these proposals is the Progressive Approach. Some of these EMDR procedures will be evaluated in a group therapy format, integrating them along with emotional regulation, dissociation, and trauma-oriented psychoeducational interventions. Patients presenting a history of severe traumatization, mostly early severe and interpersonal trauma, combined with additional significant traumatizing events in adulthood were included. In order to discriminate the specific effect of EMDR procedures, two types of groups were compared: TAU (treatment as usual: psychoeducational intervention only vs. TAU+EMDR (the same psychoeducational intervention plus EMDR specific procedures. In pre-post comparison, more variables presented positive changes in the group including EMDR procedures. In the TAU+EMDR group, 4 of the 5 measured variables presented significant and positive changes: general health (GHQ, general satisfaction (Schwartz, subjective well-being, and therapy session usefulness assessment. On the contrary, only 2 of the 5 variables in the TAU group showed statistically significant changes: general health (GHQ, and general satisfaction (Schwartz. Regarding post-test inter-group comparison, improvement in subjective well-being was related to belonging to the group that

    Full Text Available This research examined the effect of a course designed with different content on pre-service science teachers’ self-efficacy beliefs and knowledge about organizing curriculum-based trips. A pre-test post-test quasi experimental design was used in the research. One-hundred and thirty pre-service science teachers participated in the research. The research was carried out within the context of an elective course called “Informal Learning Environments in Science Education” and was conducted over 14 weeks in total for two hours per week. The research data were obtained by means of a questionnaire, self–efficacy scale for designing curriculum-based field trips (CFTSES and semi-structured focus-group interviews. As a result of the research, it was found that the course content which included in-class and out-of-school setting practices in the 3rd group was the most effective. This was followed by the 2nd group which included only in-class implementations. The first group which was supported with visuals and theoretical related presented information was the group which was the least effected. The results of the research revealed that pre-service science teachers had mainly different concerns about safety, but that this did not deter them, as they still continued to design curriculum-based field trips for learners.

    Full Text Available The aim of this study is to examine the impact of metacognitive listening strategy instruction on the listening sub-skills performance of the Iranian pre-intermediate EFL learners at the Foreign Language Center, Imam Ali University. The current study has been conducted with 64 participants. They were assigned into two groups randomly, an experimental group (n: 32 and a control group (n: 32. To determine the listening comprehension ability of the participants, a listening comprehension pretest based on the listening sub-skills was administered to the participants before the experiment. Then, the experimental group received an eight-week treatment on metacognitive listening strategies. After the treatment phase, a posttest was given to the participants in both the experimental and control group. The results of the independent t-test showed that there is a statistically significant difference (3.29>2; df = 62 between the posttest scores of the experimental group and the control group. Metacognitive strategy training promoted students’ listening comprehension remarkably; therefore, it should be integrated into the listening instruction programs to help language learners become more effective listeners.

    Many of the cognitive behavioral models and therapeutic protocols developed so far for psychological disorders and chronic diseases have proved effective through clinical research. This study aimed to determine the effectiveness of teaching cognitive-behavioral techniques on locus of control in hemodialysis patients. This controlled clinical trial study was conducted in 2015 with 76 patients selected by census and treated with a hemodialysis machine in the dialysis department of Vali-Asr Hospital in the city of Meshkinshahr. A total of four patients were excluded because of their critical conditions while the rest, who were recruited, were randomly divided into two equal groups of 36 patients as the intervention and control groups. First, the locus of control was measured in both groups through a pretest, and cognitive-behavioral techniques were then taught to the intervention group during eight 45 to 90-minute sessions. The locus of control in patients of both groups was finally re-measured through a posttest. Data were collected using Rotter's Locus of Control Inventory. The Wilcoxon test and Mann-Whitney U test were respectively used in SPSS18 for data analysis. In the pretest and posttest stages respectively, 4.8% and 14.3% of samples in the control group as well as 14.3% and 33.3% of samples in the intervention group enjoyed internal locus of control. The difference between the pretest and posttest scores of internal locus of control in the intervention group was significant (p=0.004), which indicates the positive effect of cognitive-behavioral psychotherapeutic intervention on internalization of locus of control in this group. Given the external locus of control in most of the study patients and also the positive significant effect of cognitive-behavioral psychotherapy on internalization of locus of control in this group of patients, it appears necessary to have a psychology resident present in the hemodialysis department to teach the necessary cognitive

    This study applied the concepts of the Shewhart control chart to design a pre-alarm system for the nuclear power plant control room. As a support in detecting faults, the pre-alarm system reminded the operators of a change in the system state in its early stages. Two pre-alarm types were designed to compare with the original system, and all participants were requested to monitor each simulated system under both normal and abnormal states. The tasks for the participants included shutting down the reactor, searching for procedures, monitoring system parameters and executing secondary tasks. In each trial, the task performance, mental workload and situation awareness (SA) of the participants were measured. Results indicated that participants had lower mental workload, but equal SA, when monitoring the system with either type of pre-alarm designs, and lower alarm frequency and higher secondary task performance were obtained with the pre-alarm design. Therefore, the pre-alarm system effectively assisted the operators in monitoring tasks

    The purpose of this study was to use shear bond strength (SBS) and shear fatigue strength (SFS) testing to determine the influence on dentin bonding of phosphoric acid pre-etching times before the application of self-etch adhesives. Two single-step self-etch universal adhesives [Prime & Bond Elect (EL) and Scotchbond Universal (SU)], a conventional single-step self-etch adhesive [G-aenial Bond (GB)], and a two-step self-etch adhesive [OptiBond XTR (OX)] were used. The SBS and SFS values were obtained with phosphoric acid pre-etching times of 3, 10, or 15 s before application of the adhesives, and for a control without pre-etching. For groups with 3 s of pre-etching, SU and EL showed higher SBS values than control groups. No significant difference was observed for GB among the 3 s, 10 s, and control groups, but the 15 s pre-etching group showed significantly lower SBS and SFS values than the control group. No significant difference was found for OX among the pre-etching groups. Reducing phosphoric acid pre-etching time can minimize the adverse effect on dentin bonding durability for the conventional self-etch adhesives. Furthermore, a short phosphoric acid pre-etching time enhances the dentin bonding performance of universal adhesives. © 2016 Eur J Oral Sci.

    Items to be evaluated in the group control of elevators, and a typical control system are described. A new system in which the fuzzy rule base is employed is introduced together with the configuration. The items to be evaluated are waiting time, riding time, accuracy of forecasting, energy saving, and ease of usage. The everage waiting time of less than 20 seconds with less than 3% waiting rate of more than 60 seconds is accepted as a satisfactory service condition. There are many conflicting matters in group-controlling, and the study for the controlling must deal with the optimization of multi-purpose problems. The standards for group-control evaluation differ according to building structures and the tastes of users, and an important problem is where to give emphasis of the evaluation. The TRAFFIC PATTERN LEARNING METHOD has been applied in the system for careful control to accommodate the traffic. No specific function is provided for the evaluation, but the call allocation is made by fuzzy rule-base. The configuration of a new group-control system is introduced. 7 references, 7 figures, 1 table.

    Even though patients with type 1 diabetes mellitus (T1DM) are exempted from fasting, the vast majority elect to fast against the advice of their healthcare providers. We have previously reported the incidence of wide fluctuations in blood glucose (BG) along with "unrecognized" severe hypoglycemia during Ramadan fasting in adolescents with T1DM. This report compares the continuous glucose monitoring (CGM) data during fasting in adolescents with T1DM according to their Pre-Ramadan diabetes control. Children and adolescents with T1DM who intended to fast the month of Ramadan were asked to wear the CGM during fasting for a minimum of 3 days. Hypoglycemia, hyperglycemia, and severe hyperglycemia were identified as BG 300 mg/dL (16.7 mmol/L) respectively, while normoglycemia was identified as BG 70-200 mg/dL (3.9-11.1 mmol/L). Patients were categorized as well-controlled (Group 1) and poorly controlled (Group 2) if the pre-fasting HbA1C was ≤8% (64 mmol/mol) and >8%, respectively. We compared the mean BG and the percentages of time spent in hypoglycemia, hyperglycemia, and severe hyperglycemia between the two groups using Chi-square (significant difference when P value was fasting. Our data suggest that optimal glycemic control before Ramadan may reduce the potential risks associated with fasting and minimize glucose fluctuation.

    Asynchronous e-learning allows for targeted teaching, particularly advantageous when bedside and didactic education is insufficient. An asynchronous e-learning curriculum has not been studied across multiple centers in the context of a clinical rotation. We hypothesize that an asynchronous e-learning curriculum during the pediatric emergency medicine (EM) rotation improves medical knowledge among residents and students across multiple participating centers. Trainees on pediatric EM rotations at four large pediatric centers from 2012 to 2013 were randomized in a Solomon four-group design. The experimental arms received an asynchronous e-learning curriculum consisting of nine Web-based, interactive, peer-reviewed Flash/HTML5 modules. Postrotation testing and in-training examination (ITE) scores quantified improvements in knowledge. A 2 × 2 analysis of covariance (ANCOVA) tested interaction and main effects, and Pearson's correlation tested associations between module usage, scores, and ITE scores. A total of 256 of 458 participants completed all study elements; 104 had access to asynchronous e-learning modules, and 152 were controls who used the current education standards. No pretest sensitization was found (p = 0.75). Use of asynchronous e-learning modules was associated with an improvement in posttest scores (p effect (partial η(2) = 0.19). Posttest scores correlated with ITE scores (r(2) = 0.14, p e-learning is an effective educational tool to improve knowledge in a clinical rotation. Web-based asynchronous e-learning is a promising modality to standardize education among multiple institutions with common curricula, particularly in clinical rotations where scheduling difficulties, seasonality, and variable experiences limit in-hospital learning. © 2014 by the Society for Academic Emergency Medicine.

    Full Text Available Abstract Background Hospital HIV care and public sexual health care (a Sexual Health Care Centre services were integrated to provide sexual health counselling and sexually transmitted infections (STIs testing and treatment (sexual health care to larger numbers of HIV patients. Services, need and usage were assessed using a patient perspective, which is a key factor for the success of service integration. Methods The study design was a one-group pre-test and post-test comparison of 447 HIV-infected heterosexual individuals and men who have sex with men (MSM attending a hospital-based HIV centre serving the southern region of the Netherlands. The intervention offered comprehensive sexual health care using an integrated care approach. The main outcomes were intervention uptake, patients’ pre-test care needs (n=254, and quality rating. Results Pre intervention, 43% of the patients wanted to discuss sexual health (51% MSM; 30% heterosexuals. Of these patients, 12% to 35% reported regular coverage, and up to 25% never discussed sexual health topics at their HIV care visits. Of the patients, 24% used our intervention. Usage was higher among patients who previously expressed a need to discuss sexual health. Most patients who used the integrated services were new users of public health services. STIs were detected in 13% of MSM and in none of the heterosexuals. The quality of care was rated good. Conclusions The HIV patients in our study generally considered sexual health important, but the regular counselling and testing at the HIV care visit was insufficient. The integration of public health and hospital services benefited both care sectors and their patients by addressing sexual health questions, detecting STIs, and conducting partner notification. Successful sexual health care uptake requires increased awareness among patients about their care options as well as a cultural shift among care providers.

    To verify the efficacy of group voice therapy in the stage of readiness and identify which items of the URICA-Voice range are more sensitive to post-therapy change in patients with behavioral dysphonia. An intervention study was conducted on 49 patients with behavioral dysphonia. An eclectic approach to group therapy was implemented over eight sessions, the first and last sessions consisting of assessments. The URICA-Voice range was used to evaluate the stage of readiness at pre- and post-therapy assessments. A descriptive and inferential statistical analysis was implemented for the results. Most participants were female, did not make professional use of voice, and had membranous vocal fold lesions. Most of them were in the Contemplation stage at in both moments, pre- and post-therapy. There was no significant change in the comparison of pre- and post-therapy scores. The majority of patients showed a reduction in the stage of readiness and some advanced to a higher stage. In the comparison of URICA-V range items, seven questions had equal or inferior responses in the post-therapy assessment. There was no statistical difference when comparing the pre- and post-therapy total average score of the URICA-Voice range. There were significant changes in the stage of readiness of patients in pre- and post-group speech therapy assessments.

    Full Text Available Peripheral vascular disease in pre-diabetes may involve altered sympathetically-mediated vascular control. Thus, we investigated if pre-diabetes modifies baseline sympathetic Y(1-receptor (Y(1R and α(1-receptor (α(1R control of hindlimb blood flow (Q(fem and vascular conductance (VC.Q(fem and VC were measured in pre-diabetic ZDF rats (PD and lean controls (CTRL under infusion of BIBP3226 (Y(1R antagonist, prazosin (α(1R antagonist and BIBP3226+prazosin. Neuropeptide Y (NPY concentration and Y(1R and α(1R expression were determined from hindlimb skeletal muscle samples.Baseline Q(fem and VC were similar between groups. Independent infusions of BIBP3226 and prazosin led to increases in Q(fem and VC in CTRL and PD, where responses were greater in PD (p<0.05. The percent change in VC following both drugs was also greater in PD compared to CTRL (p<0.05. As well, Q(fem and VC responses to combined blockade (BIBP3226+prazosin were greater in PD compared to CTRL (p<0.05. Interestingly, an absence of synergistic effects was observed within groups, as the sum of the VC responses to independent drug infusions was similar to responses following combined blockade. Finally, white and red vastus skeletal muscle NPY concentration, Y(1R expression and α(1R expression were greater in PD compared to CTRL.For the first time, we report heightened baseline Y(1R and α(1R sympathetic control of Q(fem and VC in pre-diabetic ZDF rats. In support, our data suggest that augmented sympathetic ligand and receptor expression in pre-diabetes may contribute to vascular dysregulation.

    Background Patients with obstructive jaundice have various pathophysiological changes that affect the liver, kidney, heart, and the immune system. There is considerable controversy as to whether temporary relief of biliary obstruction prior to major definitive surgery (pre-operative biliary drainage) is of any benefit to the patient. Objectives To assess the benefits and harms of pre-operative biliary drainage versus no pre-operative biliary drainage (direct surgery) in patients with obstructive jaundice (irrespective of a benign or malignant cause). Search methods We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Clinical Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2012. Selection criteria We included all randomised clinical trials comparing biliary drainage followed by surgery versus direct surgery, performed for obstructive jaundice, irrespective of the sample size, language, and publication status. Data collection and analysis Two authors independently assessed trials for inclusion and extracted data. We calculated the risk ratio (RR), rate ratio (RaR), or mean difference (MD) with 95% confidence intervals (CI) based on the available patient analyses. We assessed the risk of bias (systematic overestimation of benefit or systematic underestimation of harm) with components of the Cochrane risk of bias tool. We assessed the risk of play of chance (random errors) with trial sequential analysis. Main results We included six trials with 520 patients comparing pre-operative biliary drainage (265 patients) versus no pre-operative biliary drainage (255 patients). Four trials used percutaneous transhepatic biliary drainage and two trials used endoscopic sphincterotomy and stenting as the method of pre-operative biliary drainage. The risk of bias was high in all trials. The proportion of patients with malignant obstruction varied between 60

    Introduction To determine the prevalence of sexual dysfunction in pre and postmenopausal women. Material and methods A cross-sectional, descriptive, comparative study was done in climacteric women from 40 to 59 years of age. Female sexual function was evaluated with the female sexual function index (FSFI) on the day of consultation. The comparison between pre and postmenopausal women and between those with or without sexual dysfunction was done with Mann Whitney U test, χ2, and Spearman’s correlation analysis was done. Results One hundred and ten women were studied, 55 were premenopausal (group 1) and 55 postmenopausal (group 2). The median of age in group 1 was 46 (40-58) years and in group 2 it was 53 (45-60) years. Premenopausal women had higher education level than postmenopausal women (p < 0.023). From those sexually active, 62.1% had sexual dysfunction. No statistically significant difference was found in education level, religion and marital status between women with or without sexual dysfunction. No difference in sexual dysfunction was found between premenopausal (62.1%) and postmenopausal (62.5%) women, but greater sexual dysfunction was found starting from 50 years age. Age negatively correlated with FSFI score (ρ = –0.324, p < 0.001). Conclusion In postmenopausal women, those older had a greater impairment in sexual function.

    Full Text Available This study investigates the effects of teaching semantic radicals in inferring the meanings of unfamiliar characters among nonnative Chinese speakers. A total of 54 undergraduates majoring in Chinese Language from a university in Hanoi, Vietnam, who had 1 year of learning experience in Chinese were assigned to two experimental groups that received instructional intervention, called “old-for-new” semantic radical teaching, through two counterbalanced sets of semantic radicals, with one control group. All of the students completed pre- and post-tests of a sentence cloze task where they were required to choose an appropriate character that fit the sentence context among four options. The four options shared the same phonetic radicals but had different semantic radicals. The results showed that the pre-test and post-test score increases were significant for the experimental groups, but not for the control group. Most importantly, the experimental groups successfully transferred the semantic radical strategy to figure out the meanings of unfamiliar characters containing semantic radicals that had not been taught. The results demonstrate the effectiveness of teaching semantic radicals for lexical inference in sentence reading for nonnative speakers, and highlight the ability of transfer learning to acquire semantic categories of sub-lexical units (semantic radicals in Chinese characters among foreign language learners.

    Full Text Available The aim of the study was to assess whether the Aggression Replacement Training (ART programme is effective in increasing social skills and decreasing problem behaviour. The sample consisted of 232 children (mean age 10.9 yrs, SD = 2.32, their parents and teachers. The study had a quasi-experimental design with intervention and control groups. Children were recruited from six schools and four social institutions from four regions in North-West Russia from 2010 to 2013. Social skills and externalizing behaviour were assessed with the Social Skills Rating Scale and analyzed by repeated measures ANOVA (GLM. In a pre and post-test assessment, the 30-hour ART programme was associated with a significant increase in social skills when assessed by children’s self-reports. The most reliable effects of the intervention were demonstrated in the two age groups of 6-9 and 10-14 years old. When both pre and post-test were assessed by parents and teachers, children from both the intervention and control groups demonstrated more social skills and less problem behaviour. Overall results point to a significant improvement of social skills among children from the intervention groups, but an improvement in social skills and reduction of problem behaviour have also been indicated among children from the control group. Findings are discussed in view to possible diffusion of treatment from children participating in an intervention to children from control groups.

    Few studies have evaluated the association of fruit and vegetable (FV) intake and pre-diabetes. However, these studies are very limited and incomplete. Therefore, the aim of our study was to compare FV consumption and their subgroups between pre-diabetic and control subjects. This case-control study included 300 individuals, 150 subjects with normal fasting blood glucose (FBG), and 150 pre-diabetic subjects who were matched for sex and age. We collected the participants' anthropometric and physical activity data and measured their blood glucose level. A 168 items semi-quantitative food frequency questionnaire (FFQ) was used for estimating the FV intake. After adjustment for confounding variables, participants in the lower quartiles of FV and total fruit intake were more likely to experience pre-diabetes compared with those in the higher quartiles (p trend < 0.007). In addition, cruciferous vegetables, other vegetables, and berries were inversely associated with pre-diabetes (p < 0.05), although a distinct dose-response relationship was not found. Unexpectedly, higher intake of dark yellow vegetables was significantly associated with a higher chance of pre-diabetes (p trend = 0.006). Other vegetable and fruit subgroups did not show any significant relationship with this disorder. Our findings suggest that higher intake of total FV and total fruits might be associated with lower odds ratio of pre-diabetes.

    Discriminating incipient Alzheimer's disease (AD) from major depression (MD) and age related memory decline is a challenge in clinical practice. Since AD is characterized by an early loss of neuronal and functional plasticity, a dynamic test strategy, such as the testing-the-limits (TtL) approach, that measures learning capacity can be a helpful diagnostic tool. To evaluate this, a short recognition paradigm consisting of a pre-test (baseline) and two post-test conditions with an interposed encoding instruction was developed and administered to individuals with incipient AD (n = 19; Mini Mental Status Examination (MMSE) 26.5), patients with depressive disorders (n = 11; MMSE 30), and healthy controls (n = 11; MMSE 30). In addition, participants completed a set of traditional neuropsychological tests that focused on the subjects' cognitive baseline performance. Intergroup comparisons (Kruskal-Wallis, U test) revealed significantly higher post-test failure rates in AD patients. Pre-test performance of MD and AD patients did not differ. Intra-group comparisons (Friedman, Wilcoxon test) showed that all three subject samples benefit from intervention in post-test 1. In contrast to MD and healthy individuals, who revealed significantly lower failure rates in post-test 2 compared to the pre-test, AD patients did not improve. Out of the 15 traditional test scores obtained, only two discriminated simultaneously between AD and each of the other groups. Our data confirm the finding of an impaired cognitive plasticity already present in very early stages of AD and illustrate the efficiency of a dynamic test approach in identifying incipient dementia.

  19. The influence of pre-Slavic ethnic groups on the hydronymy of present-day Slovakia

    Full Text Available In this paper, we focus on the influence of pre-Slavic ethnic groups on the hydronymy of present-day Slovakia. The migration of entire ethnic groups – especially after the dissolution of the Roman Empire – led to contact between native and incoming people. Ethnic contact also affected languages of these ethnic groups, as mutual influencing and borrowing of vocabulary occurred. Incoming ethnic groups had to find their way around in the new surroundings as well as identify and distinguish important landmarks, mainly hills, mountains and streams. We can approach the issue of pre-Slavic hydronyms from two points of view: one, by analyzing the names preserved from the time period before the arrival of Slavs in the territory of Slovakia, and two, by analyzing the names whose origin some authors consider to be pre-Slavic. The oldest name of a river from the Slovak region comes from the time period before the arrival of the Slavs. It was recorded by the Roman emperor Marcus Aurelius in years 166–180 AD as Granoua. It is a record of the river Hron at which Roman legions fought against the Germanic tribes of the Marcomanni and Quadi. Several historians and linguists believe that besides the rivers Dunaj, Morava and Tisa, other names of big rivers date from before the arrival of Slavs in the central Europe. In the paper, we analyse the names Dunaj, Morava, Váh, Hron, Tisa, Nitra and Hornád.

    Current teaching in pharmacology in undergraduate medical curriculum in India is primarily drug centered and stresses imparting factual knowledge rather than on pharmacotherapeutic skills. These skills would be better developed through active learning by the students. Hence modules that will encourage active learning were developed and compared with traditional methods within the Seth GS Medical College, Mumbai. After Institutional Review Board approval, 90 second year undergraduate medical students who consented were randomized into six sub-groups, each with 15 students. Pre-test was administered. The three sub-groups were taught a topic using active learning modules (active learning groups), which included problems on case scenarios, critical appraisal of prescriptions and drug identification. The remaining three sub-groups were taught the same topic in a conventional tutorial mode (tutorial learning groups). There was crossover for the second topic. Performance was assessed using post-test. Questionnaires with Likert-scaled items were used to assess feedback on teaching technique, student interaction and group dynamics. The active and tutorial learning groups differed significantly in their post-test scores (11.3 ± 1.9 and 15.9 ± 2.7, respectively, P active learning session as interactive (vs. 37/90 students in tutorial group) and enhanced their understanding vs. 56/90 in tutorial group), aroused intellectual curiosity (47/90 students of active learning group vs. 30/90 in tutorial group) and provoked self-learning (41/90 active learning group vs. 14/90 in tutorial group). Sixty-four students in the active learning group felt that questioning each other helped in understanding the topic, which was the experience of 25/90 students in tutorial group. Nevertheless, students (55/90) preferred tutorial mode of learning to help them score better in their examinations. In this study, students preferred an active learning environment, though to pass examinations, they

    Full Text Available Abstract Background Hemodialysis patients face numerous physical and psychological stresses that result in reduced health. The aim of this study is to determine the impact of an empowerment program on self-efficacy, quality of life, clinical indicators of blood pressure and interdialytic weight gain, and laboratory results in these patients. Methods This randomized, controlled trial was conducted at Boo Ali Sina Dialysis Center, Shiraz, Iran. A total of 48 hemodialysis patients participated in this study. After acquisition of informed consent, eligible patients were randomly divided into two groups, control and experimental. Pre-test data were obtained by using a demographic data form and two questionnaires for self-efficacy and quality of life. Blood pressure and interdialytic weight gain were measured. We extracted laboratory data from patients’ charts. A six-week empowerment intervention that included four individual and two group counselling sessions was performed for the experimental group. Six weeks after intervention, post-test data were obtained from both groups in the same manner as the pre-test. Data were analyzed by ANCOVA using SPSS v11.5. Results There were no statistically significant differences in demographic variables between the groups. Pre-test mean scores for self-efficacy, quality of life, blood pressure, interdialytic weight gain and laboratory results did not differ between the groups. There was a significant difference between the experimental and control groups in terms of pre-to post-intervention changes in overall self-efficacy scores, stress reduction, and decision making, in addition to overall quality of life and all dimensions included within quality of life based on this questionnaire. Additionally, the pre- to post-intervention changes in systolic/diastolic blood pressures, interdialytic weight gain, hemoglobin and hematocrit levels significantly differed between the groups. Conclusion Our study demonstrates

    In many countries, gastric cancer is not diagnosed until an advanced stage. An Internet-based e-learning system to improve the ability of endoscopists to diagnose gastric cancer at an early stage was developed and was evaluated for its effectiveness. The study was designed as a randomized controlled trial. After receiving a pre-test, participants were randomly allocated to either an e-learning or non-e-learning group. Only those in the e-learning group gained access to the e-learning system. Two months after the pre-test, both groups received a post-test. The primary endpoint was the difference between the two groups regarding the rate of improvement of their test results. 515 endoscopists from 35 countries were assessed for eligibility, and 332 were enrolled in the study, with 166 allocated to each group. Of these, 151 participants in the e-learning group and 144 in the non-e-learning group were included in the analysis. The mean improvement rate (standard deviation) in the e-learning and non-e-learning groups was 1·24 (0·26) and 1·00 (0·16), respectively (Pe-learning system to expand knowledge and provide invaluable experience regarding the endoscopic detection of early gastric cancer (R000012039).

    Full Text Available The objective of this study is to find out whether there is a significant difference in terms of writing skills improvements between the 8th grade students of SMP N 1 Prambanan Sleman who are given teacher’s written feedback and conference and those who are not in the academic year of 2011/2012. This study involved 71 students from two groups, Class VIII B (35 students as the experimental group and Class VIII A (36 students as the control group. The experimental group was given teacher’s written feedback and conference in the writing learning process, whereas the control group was given peer’s feedback. The data were obtained by using two essay writing tests. They were administered to the two groups as the pre-test and post-test. The pre-test was given to both groups before the treatment was given and the post-test was given after the treatment finished. The data of the pre-test and post-test of both groups were analyzed by means of descriptive and inferential statistics. After the data were tested and found to be homogeneous and normal, the hypothesis was tested using the analysis of covariance (ANCOVA. The results show that there is a significant difference in the writing ability between the students who are given teacher’s written feedback and conference and those who were not. It can be seen in the result of the hypothesis testing using ANCOVA. The significant value of 0.001 is less than the significance level of 0.05 (0.001 < 0.05, which means that the data of this study are considered to have a significant difference. Therefore, the hypothesis of this study is accepted. It means that the technique of giving teacher’s written feedback and conference significantly improves the students’ writing ability in the English teaching and learning process in SMP N 1 Prambanan Sleman.

    The bundle meltdown experiment CORA-W2, representing the behavior of a Russian type VVER-1000 fuel element, with one B 4 C/stainless steel absorber rod was selected by the OECD/CSNI as International Standard Problem (ISP-36). The experimental results of CORA-W2 serve as data base for comparison with analytical predictions of the high-temperature material behavior by various code systems. The first part of the experimental results is described in KfK 5363 (1994), the second part is documented in this report which contains the destructive post-test examination results. The metallographical and analytical (SEM/EDX) post-test examinations were performed in Germany and Russia and are summarized in five individual contributions. The upper half of the bundle is completely oxidized, the lower half has kept the fuel rods relatively intact. The post-test examination results show the strong impact of the B 4 C absorber rod and the stainless steel grid spacers on the ''low-temperature'' bundle damage initiation and progression. The B 4 C absorber rod completely disappeared in the upper half of the bundle. The multicomponent melts relocated and formed coolant channel blockages on solidification with a maximum extent of about 30% in the lower part of the bundle. At temperatures above the melting point of the ZrNb1 cladding extensive fuel dissolution occurred. (orig.) [de

    Having a big number of students in content subject of a language class is a challenge for teacher since it is quite difficult to accommodate students’ critical thinking and active participation at the same time. Therefore, Hedwig strategy is aimed to give room for students to explore themselves and get involved in the materials delivered in the class. Furthermore, by having group and regroup to deliver message in Hedwig strategy, students are forced to be active participated in classroom activities. The idea of Hedwig strategy is inspired by Jigsaw and Think-Pair-Share which have existed before. To know whether Hedwig strategy is effectively applied in content subject in large language class, it is proposed to do quasi experimental study with one class as an experimental group and one class as a control group. The experimental group is treated by using Hedwig strategy. Prior to the experimental study, it is performed research and development to develop the test for pre-test and post-test. For that reason, the research problem is what test is valid and reliable for an experimental study on the effectiveness of Hedwig strategy for the 4th semester students in Language Teaching Methodology class in English Education Department Universitas Brawijaya. This research reports half of the whole plan where the researchers developed test for pre-test and posttest to measure students’ improvement in understanding Language Teaching Methodology. In short, the test developed in this study will be used to carry out experimental study as pre-test and post-test

    Early undergraduate exposure to research helps in producing physicians who are better equipped to meet their professional needs especially the analytical skills. To assess the effectiveness and acceptability of small group method in teaching research methodology. Sixth semester medical undergraduates (III MBBS-part1) of a self-financed rural medical college. The workshop was of two full days duration consisting of daily two sessions by faculty for 30 minutes, followed by group activity of about four hours and presentation by students at the end of the day. A simple 8 steps approach was used. These steps are Identify a Problem, Refine the Problem, Determine a Solution, Frame the Question, Develop a Protocol, Take Action, Write the Report and Share your Experience. A Pre-test and post-test assessment was carried out using a questionnaire followed by anonymous feedback at the end of the workshop. The responses were evaluated by blinded evaluator. There were 95 (94.8%) valid responses out of the 99 students, who attended the workshop. The mean Pre-test and post-test scores were 4.21 and 10.37 respectively and the differences were found to be significant using Wilcoxon Sign Rank test (presearch methodology workshop can play a significant role in teaching research to undergraduate students in an interesting manner. However, the long term effect of such workshops needs to be evaluated.

    Although the process of diagnosing invariably begins with a heuristic, we encourage our learners to support their diagnoses by analytical cognitive processes, such as Bayesian reasoning, in an attempt to mitigate the effects of heuristics on diagnosing. There are, however, limited data on the use ± impact of Bayesian reasoning on the accuracy of disease probability estimates. In this study our objective was to explore whether Internal Medicine residents use a Bayesian process to estimate disease probabilities by comparing their disease probability estimates to literature-derived Bayesian post-test probabilities. We gave 35 Internal Medicine residents four clinical vignettes in the form of a referral letter and asked them to estimate the post-test probability of the target condition in each case. We then compared these to literature-derived probabilities. For each vignette the estimated probability was significantly different from the literature-derived probability. For the two cases with low literature-derived probability our participants significantly overestimated the probability of these target conditions being the correct diagnosis, whereas for the two cases with high literature-derived probability the estimated probability was significantly lower than the calculated value. Our results suggest that residents generate inaccurate post-test probability estimates. Possible explanations for this include ineffective application of Bayesian reasoning, attribute substitution whereby a complex cognitive task is replaced by an easier one (e.g., a heuristic), or systematic rater bias, such as central tendency bias. Further studies are needed to identify the reasons for inaccuracy of disease probability estimates and to explore ways of improving accuracy.

    Imbalance leading to falls is common in people with multiple sclerosis (PwMS). To evaluate the effects of a balance group exercise programme (CoDuSe) on balance and walking in PwMS (Expanded Disability Status Scale, 4.0-7.5). A multi-centre, randomized, controlled single-blinded pilot study with random allocation to early or late start of exercise, with the latter group serving as control group for the physical function measures. In total, 14 supervised 60-minute exercise sessions were delivered over 7 weeks. Pretest-posttest analyses were conducted for self-reported near falls and falls in the group starting late. Primary outcome was Berg Balance Scale (BBS). A total of 51 participants were initially enrolled; three were lost to follow-up. Post-intervention, the exercise group showed statistically significant improvement ( p = 0.015) in BBS and borderline significant improvement in MS Walking Scale ( p = 0.051), both with large effect sizes (3.66; -2.89). No other significant differences were found between groups. In the group starting late, numbers of falls and near falls were statistically significantly reduced after exercise compared to before ( p balance and reduced perceived walking limitations, compared to no exercise. The intervention reduced falls and near falls frequency.

    Full Text Available Background: Declining physical activity (PA and associated health risk factors are well established. Workplace strategies to increase PA may be beneficial to ameliorate extensive sedentary behavior. This study assessed the effectiveness of two PA interventions in workplace settings. Methods: Interventions were conducted over 40 days targeting insufficiently active (<150 min/wk PA and/or obese (BMI ≥ 30 kg/m2 adults; participants were randomly allocated to instructor-led exercise sessions either after-work (n = 25 or in-work (n = 23 with a 60 minPA/day common goal, or a wait-listed control group (n = 23. The programme commenced with low-moderate physical activities and progressed to high intensity game style activities by week six. Adherence and compliance were determined using both objective measures of daily PA time from HR monitors and self-report responses to PA questionnaires. Cardiovascular and metabolic risk factors were measured pre- and post-intervention. Changes across the study were analysed using Chi square and repeat-measures ANOVA. Results: Adherence rates (completed pre and post-testing were not different between groups (76.0 vs 65.2%. Compliance for the instructor-led sessions was higher for the after-work group (70.4% vs 26.4%, respectively. Increased total PA and aerobic fitness, and decreased weight in both intervention groups were found relative to controls. The after-work group undertook more vigorous PA, and had greater weight loss and fasting blood glucose improvement, relative to in-work participants and controls. Conclusions: These workplace interventions resulted in rapid and dramatic increases in PA behaviour and important health benefits. Short, in-work PA sessions were less efficacious than longer after-work sessions.

    Full Text Available Many researchers stress the importance of lexical coherence and emphasize the need for teaching collocations at all levels of language proficiency. Thus, this study was conducted to measure the relative effectiveness of explicit (consciousness-raising approach versus implicit (input flood collocation instruction with regard to learners’ knowledge of both lexical and grammatical collocations. Ninety-five upper-intermediate learners, who were randomly assigned to the control and experimental groups, served as the participants of this study. While one of the experimental groups was provided with input flood treatment, the other group received explicit collocation instruction. In contrast, the participants in the control group did not receive any instruction on learning collocations. The results of the study, which were collected through pre-test, immediate post-test and delayed post-test, revealed that although both methods of teaching collocations proved effective, the explicit method of consciousness-raising approach was significantly superior to the implicit method of input flood treatment.

    Pre-pregnancy reduced plasma volume increases the risk on subsequent pre-eclamptic pregnancy. Reduced plasma volume is thought to reflect venous reserve capacity, especially when venous vasculature is constricted and sympathetic tone is elevated. As obesity might affect these variables and also relates to pre-eclampsia, increased body weight may underlie these observations. We hypothesized that the relationship between reduced venous reserve and preeclampsia is independent of body mass index (BMI). We compared the non-pregnant venous reserve capacity in 30 formerly pre-eclamptic women, equally divided in 3 BMI-classes (BMI 19.5-24.9, BMI 25-29.9, BMI ≥30) to 30 controls. Cases and controls were matched for BMI, age and parity. The venous reserve capacity was quantified by assessing plasma volume and venous compliance. The autonomic nervous system regulating the venous capacitance was evaluated with heart rate variability analysis in resting supine position and during positive head-up tilt (HUT). Formerly pre-eclamptic women had in supine position lower plasma volume than controls (1339 ± 79 vs 1547 ± 139 ml/m 2 (pBMI-matched controls, reduced venous reserve capacity. This is reflected by lower plasma volume and venous compliance, the autonomic balance is shifted towards sympathetic dominance and lower baroreceptor sensitivity. This suggests that not BMI, but underlying reduced venous reserve relates to pre-eclampsia. This article is protected by copyright. All rights reserved.

    Full Text Available Objectives: Substance abuse is one of the most outstanding socio-psychological hazards that can easily wreck one’s personal, family and social life. Reality Therapy is a type of Cognitive rehabilitation (known as psychosocial rehabilitation, and the application of this method in the treatment of different disorders has recently been the topic of research. The objective of this study was to examine the effectiveness of group reality therapy on the reduction of stress, anxiety and depression in addicts. Methods: A quasi-experimental study of pretest-posttest design, with a control group was conducted. The study population consisted of all addicts attending Tehran’s ‘Neda’ Rehab Clinic. First, the DASS-21 questionnaire was administered and then 40 people were selected from those who had scored average and higher. They were then randomly assigned to two test and control groups of 20 each. Analysis of co-variance was used to analyze the data, with which pretest scores were controlled, and the effect of the independent variable on posttest scores was evaluated. Results: Following the intervention, there were significant decreases in the mean scores of all three variables, i.e. stress, anxiety and depression in the test group (P<0.05. Discussion: Psychosocial rehabilitation based on reality therapy can be considered as an effective method for reducing stress, anxiety and depression in addicts and also as an adjunctive therapy in treating other ailments.

    2014-05-01

    This study describes a qualitative research design that focuses on nursing students who were aligned to different extra-curricular groups (a student representative committee, a Nurses' Day Committee and a magazine editorial team) within the School of Health. The study explores the nursing students' experiences and perceptions of belonging to an extra-curricular group within a pre-registration nursing course. Data were collected using focus groups. The findings of this study suggest that students who are members of extra-curricular groups perceive group membership to have many positive benefits. The findings were grouped into three main themes namely: employability, retention and personal gain. The findings suggest that students are clearly aware of their career development and expressed how group membership meant they were able to develop skills around employability. Students highlighted that they gained support and built lasting relationships through the groups which supported and reassured them which it was felt enabled them to progress successfully through the course. These themes reinforce the value of having established groups within a pre-registration curriculum. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Research on figuring out the ways to teach creative thinking skills via learning processes has been carried out. One of the methods applied to be efficient to teach creative thinking skills is laboratory work. Laboratory work is an important process in learning physics since students tend to find it hard to understand physical concepts if they are only taught verbally. Students will understand better when they are given real life examples and are allowed to learn the concepts through the laboratory work, whenever possible. The research was conducted at SMAN 1 Bringin by employing the quasi-experiment pre-test - post-test control group design. Creative thinking skills were measured based on four indicators: flexibility, fluency, originality, and detail. Results show that laboratory work was suitable to improve students’ fluent thinking ability with 77% students showing improvement, and it was also a fit to improve students’ original thinking with 84% students showing improvement. The experiment class revealed a gain of 0.51, taken from an average pre-test score of 45.64 compared to the average post-test score of 73.5, which is an increase of 27.86. Meanwhile, the control class resulted in a gain of 0.40, taken from an average pre-test score of 39.11 compared to the average post-test score of 83.44, which is an increase of 24.33.

    conducted. The reliability results prompted exploratory factory analyses, which resulted in two of the three subscale factors, cognitive and behavioral, being retained. One-within one-between subjects ANOVAs, independent samples t-test, and multiple linear regressions were also used to examine the impact of a multicultural science education, multimedia, and individual characteristics on students' engagement in science learning. Results. There were main effects found within subjects on posttest scores for the cognitive and behavioral subscales of student engagement. Both groups, using their respective versions of the multimedia science curriculum, reported increased engagement in science learning. There was also a statistical difference found for the experimental group at posttest on the measure of "online science was more interesting than school science." All five items unique to the posttest related to the multimedia variable were found to be significant predictors of cognitive and/or behavioral engagement. Conclusions. Engagement in science learning increased for both groups of participants; this finding is aligned with other significant research findings that more embracive and relevant pedagogies can potentially benefit all students. The significant difference found for the experimental group in relation to the multimedia usage was moderate and also may have reflected positive responses to other questions about the use of technology in science learning. As all five measures of multimedia usage were found to be significant predictors of student engagement in science learning, the indications were that: (a) technical difficulties did not impede engagement; (b) participants were better able to understand and visualize the physics concepts as they were presented in a variety of ways; (c) participants' abilities to use computers supported engagement; (d) participants in both groups found the online science curriculum more interesting compared to school science learning; and

    One of the most common symptoms observed in patients with dementia is agitation, and several non-pharmacological treatments have been used to control this symptom. However, because of limitations in research design, the benefit of non-pharmacological treatments has only been demonstrated in certain cases. The purpose of this study was to compare aroma-acupressure and aromatherapy with respect to their effects on agitation in patients with dementia. In this experimental study, the participants were randomly assigned to three groups: 56 patients were included in the aroma-acupressure group, 73 patients in the aromatherapy group, and 57 patients in the control group who received daily routine as usual without intervention. The Cohen-Mansfield Agitation Inventory (CMAI) scale and the heart rate variability (HRV) index were used to assess differences in agitation. The CMAI was used in the pre-test, post-test and post-three-week test, and the HRV was used in the pre-test, the post-test and the post-three-week test as well as every week during the four-week interventions. The CMAI scores were significantly lower in the aroma-acupressure and aromatherapy groups compared with the control group in the post-test and post-three-week assessments. Sympathetic nervous activity was significantly lower in the fourth week in the aroma-acupressure group and in the second week in the aromatherapy group, whereas parasympathetic nervous activity increased from the second week to the fourth week in the aroma-acupressure group and in the fourth week in the aromatherapy group. Aroma-acupressure had a greater effect than aromatherapy on agitation in patients with dementia. However, agitation was improved in both of the groups, which allowed the patients with dementia to become more relaxed. Future studies should continue to assess the benefits of aroma-acupressure and aromatherapy for the treatment of agitation in dementia patients. ChiCTR-TRC-14004810; Date of registration: 2014/6/12.

  10. Group performance and group learning at dynamic system control tasks

    Proper management of dynamic systems (e.g. cooling systems of nuclear power plants or production and warehousing) is important to ensure public safety and economic success. So far, research has provided broad evidence for systematic shortcomings in individuals' control performance of dynamic systems. This research aims to investigate whether groups manifest synergy (Larson, 2010) and outperform individuals and if so, what processes lead to these performance advantages. In three experiments - including simulations of a nuclear power plant and a business setting - I compare the control performance of three-person-groups to the average individual performance and to nominal groups (N = 105 groups per experiment). The nominal group condition captures the statistical advantage of aggregated group judgements not due to social interaction. First, results show a superior performance of groups compared to individuals. Second, a meta-analysis across all three experiments shows interaction-based process gains in dynamic control tasks: Interacting groups outperform the average individual performance as well as the nominal group performance. Third, group interaction leads to stable individual improvements of group members that exceed practice effects. In sum, these results provide the first unequivocal evidence for interaction-based performance gains of groups in dynamic control tasks and imply that employers should rely on groups to provide opportunities for individual learning and to foster dynamic system control at its best.

    Previous reports have suggested that action observation training (AOT) is beneficial in enhancing the early learning of new motor tasks; however, EEG-based investigation has received little attention for AOT. The purpose of this study was to illustrate the effects of AOT on hand dexterity and cortical activation in patients with post-stroke hemiparesis. Twenty patients with post-stroke hemiparesis were randomly divided into either the experimental group (EG) or control group (CG), with 10 patients in each group. Prior to the execution of motor tasks (carrying wooden blocks from one box to another), subjects in the EG and CG observed a video clip displaying the execution of the same motor task and pictures showing landscapes, respectively. Outcome measures included the box and block test (BBT) to evaluate hand dexterity and EEG-based brain mapping to detect changes in cortical activation. The BBT scores (EG: 20.50 ± 6.62 at pre-test and 24.40 ± 5.42 at post-test; CG: 20.20 ± 6.12 at pre-test and 20.60 ± 7.17 at post-test) revealed significant main effects for the time and group and significant time-by-group interactions (p < 0.05). For the subjects in the EG, topographical representations obtained with the EEG-based brain mapping system were different in each session of the AOT and remarkable changes occurred from the 2nd session of AOT. Furthermore, the middle frontal gyrus was less active at post-test than at pre-test. These findings support that AOT may be beneficial in altering cortical activation patterns and hand dexterity.

    Purpose: To examine effects of a teaching intervention on precise delineation of the prostate and rectum during planning of three-dimensional conformal radiotherapy (3D-CRT) for prostate cancer. Methods and Materials: A pretest, posttest, randomized controlled group design was used. During pretest all participants contoured prostate and rectum on planning CT. Afterward, they participated in two types of workshops. The experimental group engaged in an interactive teaching session focused on prostate and rectum MR anatomy compared with CT anatomy. The control group focused on 3D-CRT planning without mention of prostate or rectal contouring. The experimental group practiced on fused MR-CT images, whereas the control group practiced on CT images. All participants completed the posttest. Results: Thirty-one trainees (12 male, 19 female) were randomly assigned to two groups, 17 in the experimental arm, and 14 in the control group. Seventeen felt familiar or very familiar with pelvic organ contouring, 12 somewhat, and 2 had never done it. Thirteen felt confident with organ contouring, 13 somewhat, and 5 not confident. The demographics and composition of groups were analyzed with χ 2 and repeated-measures analysis of variance with the two groups (experimental or control) and two tests (pre- or posttest) as factors. Satisfaction with the course and long-term effects of the course on practice were assessed with immediate and delayed surveys. All performance variables showed a similar pattern of results. Conclusions: The training sessions improved the technical performance similarly in both groups. Participants were satisfied with the course content, and the delayed survey reflected that cognitively participants felt more confident with prostate and rectum contouring and would investigate opportunities to learn more about organ contouring.

    No known studies have tested the effectiveness of child abuse prevention programmes for adolescents in low- or middle-income countries. 'Parenting for Lifelong Health' ( http://tiny.cc/whoPLH ) is a collaborative project to develop and rigorously test abuse-prevention parenting programmes for free use in low-resource contexts. Research aims of this first pre-post trial in South Africa were: i) to identify indicative effects of the programme on child abuse and related outcomes; ii) to investigate programme safety for testing in a future randomised trial, and iii) to identify potential adaptations. Two hundred thirty participants (adolescents and their primary caregivers) were recruited from schools, welfare services and community-sampling in rural, high-poverty South Africa (no exclusion criteria). All participated in a 12-week parenting programme, implemented by local NGO childcare workers to ensure real-world external validity. Standardised pre-post measures with adolescents and caregivers were used, and paired t-tests were conducted for primary outcomes: abuse (physical, emotional abuse and neglect), adolescent behaviour problems and parenting (positive and involved parenting, poor monitoring and inconsistent discipline), and secondary outcomes: mental health, social support and substance use. Participants reported high levels of socio-economic deprivation, e.g. 60 % of adolescents had either an HIV-positive caregiver or were orphaned by AIDS, and 50 % of caregivers experienced intimate partner violence. i) indicative effects: Primary outcomes comparing pre-test and post-test assessments showed reductions reported by adolescents and caregivers in child abuse (adolescent report 63.0 % pre-test to 29.5 % post-test, caregiver report 75.5 % pre-test to 36.5 % post-test, both p child abuse and improved caregiver and adolescent outcomes. It showed high acceptability and unexpected community-level diffusion. Findings indicate needs for adaptations, and

    Full Text Available Virtual Reality is fast becoming a breakthrough in education technology and is headed towards a path where learning has become immersive. Virtual reality (VR offers both learners and educators a great opportunity to bridge gaps in the pedagogical sense. With the emergence of the Google Cardboard (GCB platform, a low-cost, virtual reality gadget comes a wide range of opportunities for educators and institutions to bring about an immersive type of learning environment for the 21st-century learner. Using Grade 6 Middle school students, this research explores the learning outcomes and student reactions using the GCB and Google Expeditions application. The study showed no significant difference in pre-test scores of the control and experimental group. There is however, a significant difference in the scores of the experimental group compared to the control group after post-test. Utilizing t-test in comparing the two groups, it was found that the mean of the post-test scores for Group A (experimental was significantly higher than Group B(control. The result of the independent samples t-test was significant, t(18 = 2.33, p = .032, suggesting that the mean of posttest score was significantly different between Groups A and B. This difference in score performance gives light to how VR can be used as a tool that enhances the learning experience. By using VR technology that is low cost and effective, more institutions will be able to help students learn better.

    Technology and computer models enhance the learning experience when appropriately utilized. Moreover, learning is significantly improved when effective visualization is combined with models of processes allowing for inquiry-based problem solving. Still, hands-on experiences in real scenarios result in better contextualization of related problems compared to virtual laboratories. Therefore, the role of scientific visualization, technology, and computer modeling is to enhance, not displace, the learning experience by supplementing real-world problem solving and experiences, although in some circumstances, they can adequately serve to take the place of reality. The key to improving scientific education is to embrace an inquiry-based approach that favorably uses technology. This study will attempt to evaluate the effect of adding interactive modeling to the geological sciences curriculum. An assessment tool, designed to assess student understanding of physical hydrology, was used to evaluate a curriculum intervention based on student learning with a data- and modeling-driven approach using COMSOL Multiphysics software. This intervention was implemented in an upper division and graduate physical hydrology course in fall 2012. Students enrolled in the course in fall 2011 served as the control group. Interactive modeling was added to the curriculum in fall 2012 to replace the analogous mathematical modeling done by hand in fall 2011. Pre- and post-test results were used to assess and report its effectiveness. Student interviews were also used to probe student reactions to both the experimental and control curricula. The pre- and post-tests asked students to describe the significant processes in the hydrological cycle and describe the laws governing these processes. Their ability to apply their knowledge in a real-world problem was also assessed. Since the pre- and post-test data failed to meet the assumption of normality, a non-parametric Kruskal-Wallis test was run to

    Physical inactivity is a serious issue for the American public. Because of conditions that result from inactivity, individuals incur close to $1 trillion USD in health-care costs, and approximately 250 000 premature deaths occur per year. Researchers have linked engaging in yoga to improved overall fitness, including improved muscular strength, muscular endurance, flexibility, and balance. Researchers have not yet investigated the impact of yoga on exercise adherence. The research team assessed the effects of 10 weeks of yoga classes held twice a week on exercise adherence in previously sedentary adults. The research team designed a randomized controlled pilot trial. The team collected data from the intervention (yoga) and control groups at baseline, midpoint, and posttest (posttest 1) and also collected data pertaining to exercise adherence for the yoga group at 5 weeks posttest (posttest 2). The pilot took place in a yoga studio in central New Jersey in the United States. The pretesting occurred at the yoga studio for all participants. Midpoint testing and posttesting occurred at the studio for the yoga group and by mail for the control group. Participants were 27 adults (mean age 51 y) who had been physically inactive for a period of at least 6 months prior to the study. Interventions The intervention group (yoga group) received hour-long hatha yoga classes that met twice a week for 10 weeks. The control group did not participate in classes during the research study; however, they were offered complimentary post research classes. Outcome Measures The study's primary outcome measure was exercise adherence as measured by the 7-day Physical Activity Recall. The secondary measures included (1) exercise self-efficacy as measured by the Multidimensional Self-Efficacy for Exercise Scale, (2) general well-being as measured by the General Well-Being Schedule, (3) exercise-group cohesion as measured by the Group Environment Questionnaire (GEQ), (4) acute feeling response

    Delirium is a common and serious complication of hospitalisation in older adults. It can lead to prolonged hospital stay, institutionalisation, and even death. However, it often remains unrecognised or is not managed adequately. The aim of this study was to evaluate the effects of an educational intervention for nursing staff on three aspects of clinical practice concerning delirium in older hospitalised patients: the frequency and correctness of screening for delirium using the 13-item Delirium Observation Screening score (DOS), and the frequency of geriatric consultations requested for older patients. The a priori expectations were that there would be an increase in all three of these outcomes. We designed an educational intervention and implemented this on two inpatient hospital units. Before providing the educational session, the nursing staff was asked to fill out two questionnaires about delirium in older hospitalised patients. The educational session was then tailored to each unit based on the results of these questionnaires. Additionally, posters and flyers with information on the screening and management of delirium were provided and participants were shown where to find additional information. Relevant data (outcomes, demographics and background patient data) were collected retrospectively from digital medical files. Data was retrospectively collected for four different time points: three pre-test and one post-test. There was a significant increase in frequency of delirium screening (P = 0.001), and both units showed an increase in the correctness of the screening. No significant effect of the educational intervention was found for the proportion of patients who received a geriatric consultation (P = 0.083). The educational intervention was fairly successful in making positive changes in clinical practice: after the educational session an improvement in the frequency and correctness of screening for delirium was observed.

    Background There are thousands of fitness-related smartphone applications (“apps”) available for free and purchase, but there is uncertainty if these apps help individuals achieve and maintain personal fitness. Technology usage attrition is also a concern among research studies on health technologies. Methods Usage of three fitness apps was examined over 5 months to assess adherence and effectiveness. Initially, 64 participants downloaded three free apps available on Android and iOS and 47 remained in the study until posttest. With a one group pre-posttest design and checkpoints at months 1, 3, and 5, exercise and exercise with fitness apps were examined in the framework of the Theory of Planned Behavior (TPB) using a validated survey. Apps were selected based on their function from the Functional Triad. Perceived fitness was also measured. T-tests, sign tests, Fisher’s exact tests, and linear and logistic regression were used to compare pre to posttests and users to non-users of the apps. Results Forty-seven participants completed both pre and posttests. Individual item scores indicated no significant change pre to posttest except for decreases observed in usefulness of using apps for exercise (attitude) (−0.78, Papps (subjective norm) (−1.02, Papps (perceived behavioral control) (−1.29, Papps over the next 2 weeks (behavioral intention) (Papps (−1.72, Papps (−2.56, Papp users (n=32) to non-users (n=15), there was only a significant difference in subscale total scores at posttest for attitude toward exercising using apps, which was significantly more favorable among users than non-users (32.3 vs. 27.6, PApp usage and effectiveness appears to have a connection to usefulness (attitude) and to perceived difficulties of exercising using apps (perceived behavioral control).

    2017-01-01

    This study aimed to examine the efficacy and maintenance of short-term (one-session) gated audiovisual speech training for improving auditory sentence identification in noise in experienced elderly hearing-aid users. Twenty-five hearing aid users (16 men and 9 women), with an average age of 70.8 years, were randomly divided into an experimental (audiovisual training, n = 14) and a control (auditory training, n = 11) group. Participants underwent gated speech identification tasks comprising Swedish consonants and words presented at 65 dB sound pressure level with a 0 dB signal-to-noise ratio (steady-state broadband noise), in audiovisual or auditory-only training conditions. The Hearing-in-Noise Test was employed to measure participants’ auditory sentence identification in noise before the training (pre-test), promptly after training (post-test), and 1 month after training (one-month follow-up). The results showed that audiovisual training improved auditory sentence identification in noise promptly after the training (post-test vs. pre-test scores); furthermore, this improvement was maintained 1 month after the training (one-month follow-up vs. pre-test scores). Such improvement was not observed in the control group, neither promptly after the training nor at the one-month follow-up. However, no significant between-groups difference nor an interaction between groups and session was observed. Conclusion: Audiovisual training may be considered in aural rehabilitation of hearing aid users to improve listening capabilities in noisy conditions. However, the lack of a significant between-groups effect (audiovisual vs. auditory) or an interaction between group and session calls for further research. PMID:28348542

    Parents play an important role in development and continuation of anxiety disorders in children. Yet the evidence on parent contribution in cognitive behavioral therapy (CBT) for childhood anxiety is limited. This open randomized trial examined the effectiveness of a parent-directed group CBT to manage children with anxiety disorders. Parents of 42 children aged 6-12 with primary anxiety disorders were allocated to a six, two-hour weekly intervention and a wait-list (WL) control. The Revised Children's Manifest Anxiety, Children's Depression Inventory, Strengths and Difficulties Questionnaire-Home Version, Depression-Anxiety-Stress Scale, Children Global Assessment Scale, and Global Relational Assessment of Functioning were used to assess children's and parents' functioning and emotional symptoms. Parents completed consumer satisfaction questionnaire. Parents in the CBT group reported significant improvement in their depressive symptoms (p=0.006) and the family functioning (p=0.04), as well as reduction in children's emotional symptoms (p=0.007). Clinician rating of children's functioning showed significant improvement in the CBT group(p=0.001). There was no significant difference in children rating of their anxiety within groups from pre- to post-intervention. Parents were satisfied mostly with the intervention. A brief parent-only CBT based intervention can be effective in the management of childhood anxiety.

    Recognizing facial expressions is an important social skill. In some psychological disorders such as schizophrenia, loss of this skill may complicate the patient's daily life. Prior research has shown that information technology may help to develop facial expression recognition skills through educational software and games. To examine if a computer game designed for teaching facial expressions would improve facial expression recognition skills of patients with schizophrenia. We developed a website composed of eight serious games. Thirty-two patients were given a pre-test composed of 21 facial expression photographs. Eighteen patients were in the study group while 14 were in the control group. Patients in the study group were asked to play the games on the website. After a period of one month, we performed a post-test for all patients. The median score of the correct answers was 17.5 in the control group whereas it was 16.5 in the study group (of 21) in pretest. The median post-test score was 18 in the control group (p=0.052) whereas it was 20 in the study group (pgames may be used for the purpose of educating people who have difficulty in recognizing facial expressions.

    Simulation training has been shown to be an effective way to teach crisis resource management (CRM) skills. Deliberate practice theory states that learners need to actively practice so that learning is effective. However, many residency programs have limited opportunities for learners to be "active" participants in simulation exercises. This study compares the effectiveness of learning CRM skills when being an active participant versus being an observer participant in simulation followed by a debriefing. Participants were randomized to two groups: active or observer. Active participants managed a simulated crisis scenario (pre-test) while paired observer participants viewed the scenario via video transmission. Then, a trained instructor debriefed participants on CRM principles. On the same day, each participant individually managed another simulated crisis scenario (post-test) and completed a post-test questionnaire. Two independent, blinded raters evaluated all videos using the Ottawa Global Rating Scale (GRS). Thirty-nine residents were included in the analysis. Normally distributed data were analyzed using paired and unpaired t-tests. Inter-rater reliability was 0.64. Active participants significantly improved from pre-test to post-test (P=0.015). There was no significant difference between the post-test performance of active participants compared to observer participants (P=0.12). We found that learning CRM principles was not superior when learners were active participants compared to being observers followed by debriefing. These findings challenge the deliberate practice theory claiming that learning requires active practice. Assigning residents as observers in simulation training and involving them in debriefing is still beneficial. Copyright © 2016 Société française d'anesthésie et de réanimation (Sfar).

    Full Text Available Investigating the efficiencies and deficiencies of reading strategies is one of the noticeable issues in the related theory and research in reading comprehension instruction. This study was to examine the impact of Directed Reading Thinking Activity (DRTA and Guided Reading (GR on reading comprehension. Sixty three Iranian students of grade one in Shahed high school in the city of Bojnourd took part in the study. They were assigned in three groups, one control and two experimental groups. The instruction lasted for ten weeks. This study utilized a pretest posttest control group in quantitative quasi- experimental design. The same reading comprehension test was administered as pre-test and post-test. The results were twofold: First, the instruction of learning strategies could foster reading comprehension skill. Second, while the explicit instruction of both strategies could improve the students' reading comprehension skill, Directed Reading Thinking Activity had a more significant positive effect than Guided Reading.

    In this study, we assessed whether an intervention designed to improve children's sibling relationships, the More Fun with Sisters and Brothers program (MFWSB), may also help parents manage their emotions more effectively. Families with at least 2 children between the ages of 4 and 8 years were randomly assigned to an intervention (n = 50) or wait-list control (n = 34) group. Parents completed pre- and posttest questionnaires on sibling warmth and agonism, their emotion regulation during sibling conflict, and their global emotion regulation styles. Program participation had a direct effect on 3 of the 4 emotion regulation outcomes for mothers. Mothers in the intervention versus control group reported lower levels of dysregulation and suppression and higher levels of reappraisal at posttest, controlling for pretest regulation scores. Additionally, path models examining posttest responses showed that participation in MFWSB led to lower levels of maternal and paternal negative reactivity in the sibling context via lower levels of sibling agonism, controlling for pretest levels of negative reactivity. Alternate path models, with parents' emotion regulation as mechanisms linking MFWSB and sibling relationship quality, were tested but not supported. Results highlight the value of a sibling-focused intervention for promoting parents' abilities to regulate their emotions. (c) 2015 APA, all rights reserved).

    Oral nifedipine is commonly used to treat pre-eclampsia, one of the most severe complications during pregnancy, but its clinical efficacy is less than ideal. Epigallocatechin gallate (EGCG), a natural compound from green tea, could benefit cardiovascular health especially hypertension. We investigated the clinical efficacy of EGCG, when complemented with oral nifedipine, in treating pre-eclampsia. A total of 350 pregnant women with severe pre-eclampsia were recruited and randomized to receive oral nifedipine, together with placebo (NIF+placebo) or EGCG (NIF+EGCG). The primary treatment outcome was the time needed to control blood pressure and interval time before a new hypertensive crisis, whereas the secondary treatment outcome was the number of treatment doses to effectively control blood pressure, maternal adverse effects and neonatal complications. Comparing NIF+EGCG group to NIF+placebo group, the time needed to control blood pressure was significantly shorter (NIF+EGCG 31.2±16.7 minutes, NIF+placebo 45.3±21.9 minutes; 95% CI 9.7-18.5 minutes), whereas interval time before a new hypertensive crisis was significantly prolonged (NIF+EGCG 7.2±2.9 hours, NIF+placebo 4.1±3.7 hours; 95% CI 2.3-3.9 hours), and the number of treatment dosages needed to effectively control blood pressure was also lower. Between the two treatment groups, no differences in incidence rates of maternal adverse effects or neonatal complications were observed. EGCG is both safe and effective in enhancing treatment efficacy of oral nifedipine against pregnancy-induced severe pre-eclampsia, but formal validation is required prior to its recommendation for use outside of clinical trials. © 2017 John Wiley & Sons Ltd.

We evaluated the effects and care costs of a specialized geriatric rehabilitation program aimed at preventing functional decline among at-risk hospitalized elderly.Methods: The prospective nonrandomized controlled trial reported here was performed in three hospitals in the Netherlands. One hospital implemented the Prevention and Reactivation Care Program (PReCaP, while two other hospitals providing usual care served as control settings. Within the PReCaP hospital we compared patients pre-implementation with patients post-implementation of the PReCaP (“within-hospital analysis”, while our nonrandomized controlled trial compared patients of the PReCaP hospital post-implementation with patients from the two control hospitals providing usual care (“between-hospital analysis”. Hospitalized patients 65 years or older and at risk of functional decline were interviewed at baseline and at 3 and 12 months using validated questionnaires to score functioning, depression, and health-related quality of life (HRQoL. We estimated costs per unit of care from hospital information systems and national data sources. We used adjusted general linear mixed models to analyze functioning and HRQoL.Results: Between-hospital analysis showed no difference in activities of daily living (ADL or instrumental activities of daily living (IADL between PReCaP patients and control groups.

    Conduct a pilot trial testing whether a new cognitive-behavioral (CB) group prevention program that incorporated cognitive-dissonance change principles was feasible and appeared effective in reducing depressive symptoms and major depressive disorder onset relative to a brochure control condition in college students with elevated depressive symptoms. 59 college students (M age = 21.8, SD = 2.3; 68% female, 70% White) were randomized to the 6-session Change Ahead group or educational brochure control condition, completing assessments at pretest, posttest, and 3-month follow-up. Recruitment and screening methods were effective and intervention attendance was high (86% attended all 6 sessions). Change Ahead participants showed medium-large reductions in depressive symptoms at posttest (M d = 0.64), though the effect attenuated by 3-month follow-up. Incidence of major depression onset at 3-month follow-up was 4% for Change Ahead participants versus 13% (difference ns). Change Ahead appears highly feasible and showed positive indications of reduced acute phase depressive symptoms and MDD onset relative to a minimal intervention control in this initial pilot. Given the brevity of the intervention, its apparent feasibility, and the lack of evidence-based depression prevention programs for college students, continued evaluation of Change Ahead appears warranted.

    Full Text Available This study attempted to determine the effect of background music while silent reading on Iranian EFL learners’ reading comprehension. The participants were 57 Iranian EFL learners between the ages of 14 and 16 in two 3rd grade high schoolclasses at pre-intermediate proficiency level. Before treatment,both experimental and control groups took a reading comprehension pretest. In the experimental group, the researchers played Mozart sonatas as background music and asked them to read the passage silently and then answer the reading comprehension questions. In the control group, the procedure was the same, but no music was played while silent reading by the students. After ten sessions, the students of both groups were asked to answer another independent but parallel form of reading section of PET as their post-test. The independent samples t-testresultsindicated that the experimental group outperformed the control group in reading comprehension posttest, and listening to background music while silent reading had a significantly positive effect on Iranian EFL learners’ reading comprehension. The results of the present study have implications for EFL students, teachers, and teacher educators as well as syllabus designers and materials developers.

In this quasi-experimental study, 64 students in term 4 in nursing college of Bukan and Miandoab were included in the study based on knowledge and performance questionnaire including 15 questions based on knowledge and 5 questions based on performance on care-taking in patients with diabetes were used as data collection tool whose reliability was confirmed by cronbach alpha (r=0.83 by the researcher. To compare the mean score of knowledge and performance in each group in pre-test step and post-test step, pair –t test and to compare mean of scores in two groups of control and intervention, the independent t- test was used. There was not significant statistical difference between two groups in pre terms of knowledge and performance score (p=0.784. There was significant difference between the mean of knowledge scores and diabetes performance in the post-test in the team-based learning group and lecture-based learning group (p=0.001. There was significant difference between the mean score of knowledge of diabetes care in pre-test and post-test in base learning groups (p=0.001. In both methods team-based and lecture-based learning approaches resulted in improvement in learning in students, but the rate of learning in the team-based learning approach is greater compared to that of lecturebased learning and it is recommended that this method be used as a higher education method in the education of students.

    Full Text Available Background and Aim: The majority of people experience problems and stressors, such as job layoffs and illnesses during their lives. However, the way people cope with stress varies. According to previous research, use of effective coping strategies can significantly reduce stress and tension. The aim of the present study was to investigate the effectiveness of stress coping strategies on hearing-impaired students.Methods: This is a quasi-experimental study with pre-test, post-test, and control group. The sample consisted of 40 hearing-impaired male students of guidance and high schools of the city of Sari, Iran, in the years 2010 and 2011. They were randomly selected and assigned to two experimental and control groups (n=20. The data collection tool was the General Health Questionnaire-28. The experimental group was administered eight sessions of stress coping strategies based on cognitive-behavioral techniques two hours weekly. Data were analyzed using statistical indices including mean, standard deviation, and two-way analysis of variance.Results: There was a significant difference between the pre-test and post-test scores in the subscales of somatic symptoms, anxiety and insomnia, depression, and social function (p<0.05. Moreover, after the eight sessions the rate of general health of the experimental group was higher than the control group.Conclusion: Stress coping strategies based on cognitive-behavioral techniques increased the general health of hearing-impaired people. Therefore, stress management training should be developed and expanded as an appropriate intervention.

    This study examined the effectiveness of two approaches used in elementary schools to improve children's handwriting. Participants were 72 New York City public school students from the first and second grades. A nonequivalent pretest-posttest group design was used in which students engaged in handwriting activities using two approaches: intensive handwriting practice and visual-perceptual-motor activities. Handwriting speed, legibility, and visual-motor skills were examined after a 12-wk Handwriting Club using multivariate analysis of variance. The results showed that students in the intensive handwriting practice group demonstrated significant improvements in handwriting legibility compared with students in the visual-perceptual-motor activity group. No significant effects in handwriting speed and visual-motor skills were found between the students in intensive handwriting practice group and the students in visual-perceptual-motor activities group. The Handwriting Club model is a natural intervention that fits easily into existing school curriculums and can be an effective short-term intervention (response to intervention Tier II).

    Didactic lectures are frequently used to improve compliance with practice guidelines. This study assessed the knowledge of health-care providers (HCPs) at a tertiary-care hospital of its evidence-based thromboprophylaxis guidelines and the impact of didactic lectures on their knowledge. The hospital launched a multifaceted approach to improve thromboprophylaxis practices, which included posters, a pocket-size guidelines summary and didactic lectures during the annual thromboprophylaxis awareness days. A self-administered questionnaire was distributed to HCPs before and after lectures on thromboprophylaxis guidelines (June 2010). The questionnaire, formulated and validated by two physicians, two nurses and a clinical pharmacist, covered various subjects such as risk stratification, anticoagulant dosing and the choice of anticoagulants in specific clinical situations. Seventy-two and 63 HCPs submitted the pre- and post-test, respectively (62% physicians, 28% nurses, from different clinical disciplines). The mean scores were 7.8 ± 2.1 (median = 8.0, range = 2-12, maximum possible score = 15) for the pre-test and 8.4 ± 1.8 for the post-test, P = 0.053. There was no significant difference in the pre-test scores of nurses and physicians (7.9 ± 1.7 and 8.2 ± 2.4, respectively, P = 0.67). For the 35 HCPs who completed the pre- and post-tests, their scores were 7.7 ± 1.7 and 8.8 ± 1.6, respectively, P = 0.003. Knowledge of appropriate anticoagulant administration in specific clinical situations was frequently inadequate, with approximately two-thirds of participants failing to adjust low-molecular-weight heparin doses in patients with renal failure. Education via didactic lectures resulted in a modest improvement of HCPs' knowledge of thromboprophylaxis guidelines. This supports the need for a multifaceted approach to improve the awareness and implementation of thromboprophylaxis guidelines.

    Full Text Available BACKGROUND AND AIMS: Examinations today are often computerized and the primary motivation and curriculum is often based on the examinations. This study aims to test if competition widgets in e-learning quiz modules improve post-test and follow-up test results and self-evaluation. The secondary aim is to evaluate improvements during the training period comparing test-results and number of tests taken. METHODS: Two groups were randomly assigned to either a quiz-module with competition widgets or a module without. Pre-, post- and follow up test-results were recorded. Time used within the modules was measured and students reported time studying. Students were able to choose questions from former examinations in the quiz-module. RESULTS: Students from the competing group were significantly better at both post-and follow-up-test and had a significantly better overall learning efficiency than those from the non-competing group. They were also significantly better at guessing their post-test results. CONCLUSION: Quiz modules with competition widgets motivate students to become more active during the module and stimulate better total efficiency. They also generate improved self-awareness regarding post-test-results.

    Full Text Available In Recent studies underline the fact that adolescents are, at many times, likely to experience serious communication problems with their families and close environments. So, the aim of this study is to determine positive impact of sport-related games, which are performed as extracurricular activities, on high school students’ communication skills. In the study, pre, & post-tests was utilized with the control group’s experimental patterns. Two participant groups were made up of totally 30 high school students, 15 of whom would be in the experimental group and the rest of whom were in the control group. The former group was given sport- related 20 applications for 10 weeks during which the latter group would not deal with any extracurricular activities. Meanwhile, before and after the applications, data was collected by means of “The Communication Skills Scale” which was developed by Korkut (1996 and then analysed through “two-way ANCOVA” test techniques. Results clarify that the considerable gap in scores of the students’ pre, & post-tests perception concerning their communication skills are clearly attributed to sport-related games and it was also established that scores of the students in the experimental group were meaningfully higher than ones in the control group. However, perception of communication skills in the both groups was not significantly different by sex of the students. Moreover, the common effect of sex and participation on sport- related games was not found statistically meaningful in terms of communication skills. Consequently, it could be said that sport-related games impact positively communication skills.

    Mass fatality incidents can overwhelm local, state and national resources quickly. Dental hygienists are widely distributed and have the potential to increase response teams' capacity. However, appropriate training is required. The literature is void of addressing this type of training for dental hygienists and scant in dentistry. Hence, the purpose of this study was to assess one facet of such training: Whether the use of multimedia is likely to enhance educational outcomes related to mass fatality training. A randomized, double-blind, pre- and post-test design was used to evaluate the effectiveness of comparable educational modules for 2 groups: a control group (n=19) that received low media training and a treatment group (n=20) that received multimedia training. Participants were second-year, baccalaureate dental hygiene students. Study instruments included a multiple-choice examination, a clinical competency-based radiology lab scored via a standardized rubric, and an assessment of interest in mass fatality education as a specialty. ANOVA was used to analyze results. Participants' pre- and post-test scores and clinical competency-based radiology lab scores increased following both educational approaches. Interest in mass fatality training also increased significantly for all participants (p=0.45). There was no significant difference in pre- and post-test multiple choice scores (p=0.6455), interest (p=0.9133) or overall competency-based radiology lab scores (p=0.997) between groups. Various educational technique may be effective for mass fatality training. However, mass fatality training that incorporates multimedia is an appropriate avenue for training instruction. Continued research about multimedia's role in this specialty area is encouraged. Copyright © 2015 The American Dental Hygienists’ Association.

    [Purpose] The purpose of this study was to investigate not only the effects of stimulatory vibration but also the retained effects 2 weeks after the last session of the intervention. [Subjects and Methods] Ten subjects with post-stroke hemiplegia were recruited in this study. The experimental group (EG) received vibratory stimulation for 30 minutes in each session, three times a week for 2 weeks. Grip strength (GS), box-and-block test (BBT), and Weinstein monofilament were used to assess hand strength, dexterity, and sensory in the affected hand, respectively. [Results] A significant difference was found between the pre- and post-follow-up BBT. Significant differences were found among the pre-posttest, post-follow-up test, and pre-follow-up test results for GS and BBT. [Conclusion] This study was conducted with 10 subjects, without a control group, to verify the pure effect of the intervention. As a result, significant positive effects were observed in the post-test and follow-up test of GS and BBT. Therefore, repeated vibratory stimulation influenced GS and BBT after the 2-week intervention and retained the effect for 2 more weeks.

    Full Text Available We used a novel approach to examine whether it is possible to improve the perceptual–cognitive skill of pattern recognition using a video-based training intervention. Moreover, we investigated whether any improvements in pattern recognition transfer to an improved ability to make anticipation judgments. Finally, we compared the relative effectiveness of verbal and visual guidance interventions compared to a group that merely viewed the same sequences without any intervention and a control group that only completed pre- and post-tests. We found a significant effect for time of testing. Participants were more sensitive in their ability to perceive patterns and distinguish between novel and familiar sequences at post- compared to pre-test. However, this improvement was not influenced by the nature of the intervention, despite some trends in the data. An analysis of anticipation accuracy showed no change from pre- to post-test following the pattern recognition training intervention, suggesting that the link between pattern perception and anticipation may not be strong. We present a series of recommendations for scientists and practitioners when employing training methods to improve pattern recognition and anticipation.

    The present study offers a cross-cultural examination of the effect of prayer on forgiveness. American (n = 51) and Indian (n = 100) participants either prayed for their romantic partner (prayer condition) or described their romantic partner's physical attributes (control condition). Prayers were self-guided and lasted 3 minutes. Pre-test and post-test measures of retaliation were completed. Results showed that participants in the prayer group showed statistically significant decreases in retaliation motives from pre-test to post-test and the magnitude of this change was not different across cultures. Control groups in both cultures showed no change. Because of the religious diversity present in the Indian sample, the robustness of the effect of prayer on forgiveness was tested across Christian, Hindu and Muslim Indians. Religious affiliation did not moderate the effect of prayer on forgiveness in this sample. Results suggest that a brief prayer is capable of producing real change in forgiveness and this change is consistent across American and Indian cultures and across three different religious groups in India. Brief prayer for others that enhances forgiveness may be useful for individuals in close relationships, in certain counselling settings and for people in many different walks of life. © 2015 International Union of Psychological Science.

    Affhalter, Maria Geralyn

    An action research project using science inquiry labs and cooperative learning groups examined the effects of same-gender and co-educational classrooms on science achievement and teacher-assigned or self-selected group roles on students' role preferences. Fifty-nine seventh grade students from a small rural school district participated in two inquiry labs in co-educational classrooms or in an all-female classroom, as determined by parents at the beginning of the academic year. Students were assigned to the same cooperative groups for the duration of the study. Pretests and posttests were administered for each inquiry-based science lab. Posttest assessments included questions for student reflection on role assignment and role preference. Instruction did not vary and a female science teacher taught all class sections. The same-gender classroom and co-ed classrooms produced similar science achievement scores on posttests. Students' cooperative group roles, whether teacher-assigned or self-selected, produced similar science achievement scores on posttests. Male and female students shared equally in favorable and unfavorable reactions to their group roles during the science inquiry labs. Reflections on the selection of the leader role revealed a need for females in co-ed groups to be "in charge". When reflecting on her favorite role of leader, one female student in a co-ed group stated, "I like to have people actually listen to me".

    To evaluate the effects of 10 weeks of aerobic exercise on depressive and anxiety symptoms and self-esteem of breast cancer survivors. Experimental, crossover. Midwestern university town. Twenty-four breast cancer survivors (mean time following surgery 41.8 months; ranging from 1 to 99 months) recruited via mail and cancer support groups. The mean age of the sample was 48.9 years. Subjects were assigned randomly into exercise (EX), exercise-plus-behavior modification (EX + BM), and control groups. EX and EX + BM groups exercised aerobically four days/week at > or = 60% of age-predicted maximum heart rate for 10 weeks. Data were collected pretest, post-test, and crossover (12 weeks following post-test). Because pretest or post-test scores showed no statistical differences between EX and EX + BM groups, data were combined to form one group. Aerobic exercise (four days/ week; 30-40 minutes/session), depression, (Beck Depression inventory), anxiety (Speilberger State-Trait Anxiety Inventory), and self-esteem (Rosenberg Self-Esteem Inventory). Pre- to post-test analyses revealed that women who exercised had significantly less depression and state and trait anxiety over time compared to controls. After the crossover, the control group demonstrated comparable improvements in both depressive and state anxiety scores. Self-esteem did not change significantly. Subjects who received exercise recommendations from their physicians exercised significantly more than subjects who received no recommendation. Mild to moderate aerobic exercise may be of therapeutic value to breast cancer survivors with respect to depressive and anxiety symptoms but not to self-esteem. A physician's recommendation to exercise appears to be an important factor in a patient's exercise adherence. To Improve depressive and anxiety symptoms following breast cancer surgery, healthcare professionals should consider recommending mild to moderate exercise.

    To foster nursing professionals, nursing education requires the integration of knowledge and practice. Nursing students in their senior year experience considerable stress in performing the core nursing skills because, typically, they have limited opportunities to practice these skills in their clinical practicum. Therefore, nurse educators should revise the nursing curricula to focus on core nursing skills. To identify the effect of an intensive clinical skills course for senior nursing students on their self-confidence and clinical competence. A quasi-experimental post-test study. A university in South Korea during the 2015-2016 academic year. A convenience sample of 162 senior nursing students. The experimental group (n=79) underwent the intensive clinical skills course, whereas the control group (n=83) did not. During the course, students repeatedly practiced the 20 items that make up the core basic nursing skills using clinical scenarios. Participants' self-confidence in the core clinical nursing skills was measured using a 10-point scale, while their clinical competence with these skills was measured using the core clinical nursing skills checklist. Independent t-test and chi-square tests were used to analyze the data. The mean scores in self-confidence and clinical competence were higher in the experimental group than in the control group. This intensive clinical skills courses had a positive effect on senior nursing students' self-confidence and clinical competence for the core clinical nursing skills. This study emphasizes the importance of reeducation using a clinical skills course during the transition from student to nursing professional. Copyright © 2017. Published by Elsevier Ltd.

    This study replicated and extended previous evaluations of the Signs of Suicide (SOS) prevention program in a high school population using a more rigorous pre-test post-test randomized control design than used in previous SOS evaluations in high schools (Aseltine and DeMartino 2004; Aseltine et al. 2007). SOS was presented to an ethnically diverse group of ninth grade students in technical high schools in Connecticut. After controlling for the pre-test reports of suicide behaviors, exposure to the SOS program was associated with significantly fewer self-reported suicide attempts in the 3 months following the program. Ninth grade students in the intervention group were approximately 64% less likely to report a suicide attempt in the past 3 months compared with students in the control group. Similarly, exposure to the SOS program resulted in greater knowledge of depression and suicide and more favorable attitudes toward (1) intervening with friends who may be exhibiting signs of suicidal intent and (2) getting help for themselves if they were depressed or suicidal. In addition, high-risk SOS participants, defined as those with a lifetime history of suicide attempt, were significantly less likely to report planning a suicide in the 3 months following the program compared to lower-risk participants. Differential attrition is the most serious limitation of the study; participants in the intervention group who reported a suicide attempt in the previous 3 months at baseline were more likely to be missing at post-test than their counterparts in the control group.

    Caregivers of patients with heart failure experience burden and negative health outcomes. Adequate support for family caregivers improves their well-being and the quality of care provided to the patients. However, little is known about the benefits of interventions for caregivers of patients with heart failure in China. To test the effects of a multidisciplinary supportive program for family caregivers on caregiver burden, quality of life, and depression. A randomized controlled design with repeated measures was used in this study. A total of 118 participants were randomized into experimental (n=59) and control groups (n=59) from May to December 2014 in one hospital in Chengdu, People's Republic of China. Participants in the experimental group received a 3-month multidisciplinary supportive program, consisting of three 60-min sessions of group classes, three 30-min peer support groups, and regular telephone follow-ups and consultations, while participants in the control group received usual care only. Outcomes were caregiver burden, quality of life, and depression. Data were collected at baseline, post-test (3 months after discharge), and 3 months after post-test (6 months after discharge). The repeated measures analysis of variance was used to examine the effects of groups, changes over time, and time-group interaction on outcome variables. There were significant improvements in caregiver burden, mental health, and depression after post-test and 3 months after post-test in the experimental group. However, there was no significant improvement in caregivers' physical health at either 3 or 6 months following discharge. A multidisciplinary supportive program for caregivers of heart failure patients had positive effects and provides a unique perspective of an intervention considering Chinese culture and customs.

    The present document deals with Relap5/Mod3.2 analysis of the International Standard Problem (ISP-42) exercise performed in PANDA facility on April 21-22, 1998. PANDA is installed at PSI (Paul Scherrer Institute). PANDA is a large-scale thermal-hydraulic test facility suitable for the simulation of passive containment for Advanced Light Water Reactors (ALWR). The work focuses phase A of the ISP-42 experiment, including the break in the main steam line, and the Passive Containment Cooling System Start-Up. The objective is to investigate the start-up phenomenology of passive cooling system when steam is injected into cold vessel filled with air and to observe the resulting system behavior. A detailed nodalization was set-up at the University of Pisa, in order to model 3-D flow paths with a 1-D code. The comparison between pre-test predictions and experimental data is discussed. Overall time behavior is reasonably well predicted, showing a rather good and robust overall code behavior in the simulation of the global test scenario. The results of a preliminary post-test analysis are discussed, including the comparison with the experimental data. (authors)

    Full Text Available Infection in pregnancy may be involved in the aetiology of pre-eclampsia. However, a clear association between acute maternal infection and pre-eclampsia has not been established. We assessed whether acute urinary tract infection, respiratory tract infection, and antibiotic drug prescriptions in pregnancy (a likely proxy for maternal infection are associated with an increased risk of pre-eclampsia.We used a matched nested case-control design and data from the UK General Practice Research Database to examine the association between maternal infection and pre-eclampsia. Primiparous women aged at least 13 years and registered with a participating practice between January 1987 and October 2007 were eligible for inclusion. We selected all cases of pre-eclampsia and a random sample of primiparous women without pre-eclampsia (controls. Cases (n=1533 were individually matched with up to ten controls (n=14236 on practice and year of delivery. We calculated odds ratios and 95% confidence intervals for pre-eclampsia comparing women exposed and unexposed to infection using multivariable conditional logistic regression. After adjusting for maternal age, pre-gestational hypertension, diabetes, renal disease and multifetal gestation, the odds of pre-eclampsia were increased in women prescribed antibiotic drugs (adjusted odds ratio 1.28;1.14-1.44 and in women with urinary tract infection (adjusted odds ratio 1.22;1.03-1.45. We found no association with maternal respiratory tract infection (adjusted odds ratio 0.91;0.72-1.16. Further adjustment for maternal smoking and pre-pregnancy body mass index made no difference to our findings.Women who acquire a urinary infection during pregnancy, but not those who have a respiratory infection, are at an increased risk of pre-eclampsia. Maternal antibiotic prescriptions are also associated with an increased risk. Further research is required to elucidate the underlying mechanism of this association and to determine

    Workplace design can impact workday physical activity (PA) and sedentary time. The purpose of this study was to evaluate PA behavior among university employees before and after moving into a new building. A pre-post, experimental versus control group study design was used. PA data were collected using surveys and accelerometers from university faculty and staff. Accelerometry was used to compare those moving into the new building (MOVERS) and those remaining in existing buildings (NONMOVERS) and from a control group (CONTROLS). Survey results showed increased self-reported PA for MOVERS and NONMOVERS. All 3 groups significantly increased in objectively collected daily energy expenditure and steps per day. The greatest steps per day increase was in CONTROLS (29.8%) compared with MOVERS (27.5%) and NONMOVERS (15.9%), but there were no significant differences between groups at pretest or posttest. Self-reported and objectively measured PA increased from pretest to posttest in all groups; thus, the increase cannot be attributed to the new building. Confounding factors may include contamination bias due to proximity of control site to experimental site and introduction of a university PA tracking contest during postdata collection. Methodology and results can inform future studies on best design practices for increasing PA.

    Stress, pre-term labour and birth outcomes Preliminary studies have suggested that stress may be associated with the onset, treatment and outcomes of pre-term labour; however, a systematic comparison of the stress of women with and without pre-term labour has not been reported. Therefore, the purpose of this exploratory study was to compare the stress (daily hassles and mood states) and birth outcomes of black and white women who experienced pre-term labour (PTL) during pregnancy with those who did not. The convenience sample consisted of 35 pregnant women hospitalized in 1996-1997 for the treatment of PTL (24-35 weeks gestation) and 35 controls matched on age, race, parity, gestational age and method of hospital payment. Women in the PTL group had significantly higher tension-anxiety and depression-dejection on the Profile of Mood States (POMS), lower mean birthweight and mean gestational age, and a higher percentage of babies born <37 weeks and weighing 2500 g or less. Black women in the PTL group and white women in the control group had significantly higher scores on the fatigue sub-scale of the POMS and the work and future security sub-scales of the Daily Hassles Scale. Women in the PTL group whose babies weighed 2500 g or less had significantly higher scores on the health, inner concern and financial responsibility sub-scales of the Daily Hassles Scale. The findings from this study indicate the need for further exploration of the interaction of race and stress in understanding and preventing PTL and low birthweight and the need to examine the role of social support in preventing pre-term birth after an episode of PTL.

    1986-01-01

    Transient Reactor Test (TREAT) Facility experiment M2 was performed to evaluate the transient behavior of metal-alloy fuel under accident conditions to investigate the inherent safety features of the fuel in integral fast reactor (IFR) system designs. Objectives were to obtain early information on the key fuel behavior characteristics at transient overpower (TOP) conditions in metal-fueled fast reactors; namely, margin to cladding breach and extent of axial self-extrusion of fuel within intact cladding. The onset of cladding breaching depends on fuel/cladding eutectic formation, as well as cladding pressurization and melting. Driving forces for fuel extrusion are fission gas, liquid sodium, and volatile fission products trapped within the fuel matrix. The post-test examination provided data essential for correctly modeling fuel behavior in accident codes

    Full Text Available The purpose of present study was to investigate the effect of life skills training on the mother-child relationship in mothers of children with hearing problems. The study’s procedure was experimental with pretest-posttest design employing a control group. The participants include 36 mothers of children with hearing problems in Shiraz who were selected by an available sampling method and assigned into experimental and control group, randomly; hence, each group included 18 mothers. Both groups had undergone a pre-test. The experimental group received life skills training in 12 sessions while the control group did not. After the intervention period the post-test was administered for both groups. The Roth mother-child relationship strategies scale (1961 was employed to assess the mother-child relationship strategies. The data analyses by ANCOVA showed that there was a significant effect in the mean score of mother-child relationship in mothers of children with hearing problems in the experimental group (p<0/0001 and increased the acceptance of child and reduced the overprotection, the overindulgence and the child rejection among the mothers of experimental group. Therefore, life skills training program construction and employment are highly recommendable to improve mother-child relationship strategies among mothers of children with hearing problems.

    2015-09-01

    This experiment tested whether pre-exposing a taste would reduce its ability to overshadow conditioning to a target taste and whether this effect would depend on the delay between pre-exposure and conditioning. Two groups of rats were pre-exposed to an interfering taste (HCl) either a week before conditioning (Group Distal) or the day preceding conditioning (Group Proximal). In the single conditioning trial, rats were given the target taste (sucrose) and 65min later were injected with lithium. The groups differed as to what they were given to drink 50min after sucrose: The Distal, Proximal and Novel groups were given HCl, while the Control group was given water. Pre-exposure to HCl reduced overshadowing of the sucrose aversion by HCl in Group Proximal but not in Group Distal. Possible explanations for the latter result include extinction of the context-HCl association and loss of context control over an HCl-no outcome association. Copyright © 2015 Elsevier B.V.

    Full Text Available Flipped learning, one of the most popular and conspicuous instructional models of recent time, can be considered as a pedagogical approach in which the typical lecture and homework elements of a course are reversed. Flipped learning transforms classrooms into interactive and dynamic places where the teacher guides the students and facilitates their learning. The current study explores the impact of flipped instruction on students’ foreign language writing skill which is often perceived as boring, complex and difficult by English as a Foreign Language (EFL learners. The study compares flipped and traditional face-to-face writing classes on the basis of writing performances. Employing a pre- and post-test true experimental design with a control group, the study is based on a mixed-method research. The experimental group consisting of 23 English Language Teaching (ELT students attending preparatory class were instructed for fifteen weeks through Flipped Writing Class Model while the control group comprising 20 ELT preparatory class students followed traditional face-to-face lecture-based writing class. Independent and paired samples t-tests were carried out for the analyses of the data gathered through the pre-and post-tests. The results indicated that there was a statistically significant difference between the experimental and control groups in terms of their writing performances based on the employed rubric. It was found that the students in the experimental group outperformed the students in the control group after the treatment process. The results of the study also revealed that the great majority of the students in the experimental group held positive attitudes towards Flipped Writing Class Model.

    Education on the subject of groundwater is crucial for sustainability. Nevertheless, international studies with students across different age groups have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Drawing from international research, a multimedia learning program Zwischen Regenwolke und Wasserhahn (between the rain cloud and the tap) was developed, which incorporates specific insights from the fields of conceptual change research, multimedia research, and the model of educational reconstruction. The effectiveness of the learning program was ascertained by means of two studies with Austrian seventh grade pupils as well as teacher-training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge of groundwater were determined in a pre- and post-test. The pupils and students greatly benefitted from working through the learning software independently. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results indicate that theory-guided multimedia learning programs can play an important role in the transfer of research results to classroom settings, especially in science education.

    Pre-harvest sprouting results in significant economic loss for the grain industry around the world. Lack of adequate seed dormancy is the major reason for pre-harvest sprouting in the field under wet weather conditions. Although this trait is governed by multiple genes it is also highly heritable....... A major QTL controlling both pre-harvest sprouting and seed dormancy has been identified on the long arm of barley chromosome 5H, and it explains over 70% of the phenotypic variation. Comparative genomics approaches among barley, wheat and rice were used to identify candidate gene(s) controlling seed...... dormancy and hence one aspect of pre-harvest sprouting. The barley seed dormancy/pre-harvest sprouting QTL was located in a region that showed good synteny with the terminal end of the long arm of rice chromosome 3. The rice DNA sequences were annotated and a gene encoding GA20-oxidase was identified...

    Clinical nursing practice is important because it helps nursing students experience realities of clinical nursing that cannot be learned through theoretical education. This study aimed to evaluate the effect of an interactive nursing skills mobile application for nursing students. Sixty-six senior nursing students were randomly assigned to experimental or control groups. The experimental group used an interactive nursing skills mobile application for 1 week. The control group was provided with a mobile application containing noninteractive nursing video contents for 1 week. Before (pre-test) and 1 week after (post-test) using the mobile application, participants' knowledge of clinical nursing skills, self-efficacy of nursing practice, and nursing skills performance were assessed. The experimental group showed a significantly higher value for knowledge after 1 week of treatment via their mobile application than the control group (t = 3.34, p = .001). In addition, they showed significantly improved self-efficacy before and after intervention (t = 2.46, p = .017) than the control group. The experimental group's nursing skills performance was also significantly enhanced after intervention (t = 7.05, p mobile application with systematic contents was an effective method for students to experience practical nursing skills. Developing and applying a mobile application with other nursing contents that can be effectively used across all range of nursing students is recommended. Copyright © 2018.

The study sample included 110 people; 55 in the test group, and 55 in the control group. They were randomly selected and replaced through the single-stage cluster sampling. To collect the data, a questionnaire was used. Pre-test was performed before the training session in two groups. After training course, a post-test was taken. For data analysis, the independent t-test, was used. The average pre-test score of the test group was 182 +/- 34.15, while for the control group it was 191 +/- 30.37 (p motivation in learning increased significantly after imparting training in note-taking skills. Authorities in the educational system should invest more for promotion of such skills.

    The present research was conducted to study the effect of play therapy on reducing behavioral problems of children with oppositional defiant disorder. Using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected. Among kindergartens of these areas, 3 kindergartens which were supported by the welfare organization were randomly selected. Of all the pre-school children of these 3 kindergartens, 40 children who could have behavioral disorder, according to their teachers and parents, were carefully tested. Of them, 16 children who showed severe symptoms of oppositional defiant disorder, were selected via the results obtained from the child symptom inventory questionnaire (CSI-4), teacher's form, and a researcher-made self-control checklist, Then, the subjects were randomly divided into one control and one experimental group. This research is quasi-experimental, and is conducted using pre-test, post-test, and control group. Values of the calculated F for oppositional defiant disorder in control group and experimental group was meaningful after fixing the effect of pre-test (Pplay therapy reduced severity of ADHD in those children in experimental group compared to those in control group who did not receive such instructions. Results of this research demonstrates that children's disobedience can be reduced by play therapy.

    Full Text Available Hemodialysis as the most common renal replacement therapy alone cannot ensure the health and survival of the patient's life and along with it, training and consulting about self-care and adherence is one of the fundamental pillars of treatment. This study was conducted to determine the impact of telenursing consultation by using networks to promote the self-efficacy and weight control in patients treating with hemodialysis. This study was a clinical trial for two groups and had a pre-test and two post-test. 52 patients under treatment by hemodialysis were divided randomly into two groups of experimental and control groups. The experimental group received consultations by using the telegram software and the control group received usual nursing care for a month. The data were collected by the weight control of the patients before and after the sessions of hemodialysis and general self-efficacy questionnaire and were analyzed by SPSS software version 20, and using descriptive statistics and analytical tests. The two groups did not have a significant statistically differences in demographic variables. The average rates of the self-efficacy after intervention in the experimental group was significantly more than the control group and also the average overweight after the intervention was significantly lower. telenursing consultation by using the social networks is effective on the improvement of self-efficacy and weight control in patients treating with hemodialysis and due to the shortage of nurses and their high volume of work it can be used as a new way for training.

    The purpose of this study was to determine the effectiveness of an inquiry approach to science and language teaching to further develop classification and oral communication skills of bilingual Mexican American third graders. A random sample consisting of 64 subjects was selected for experimental and control groups from a population of 120 bilingual Mexican American third graders. The Solomon Four-Group experimental design was employed. Pre- and posttesting was performed by use of the Goldstein-Sheerer Object Sorting Test, (GSOST) and the Test of Oral Communication Skills, (TOCS). The experimental group participated in a sequential series of science lessons which required manipulation of objects, exploration, peer interaction, and teacher-pupil interaction. The children made observations and comparisons of familiar objects and then grouped them on the basis of perceived and inferred attributes. Children worked individually and in small groups. Analysis of variance procedures was used on the posttest scores to determine if there was a significant improvement in classification and oral communication skills in the experimental group. The results on the posttest scores indicated a significant improvement at the 0.01 level for the experimental group in both classification and oral communication skills. It was concluded that participation in the science inquiry lessons facilitated the development of classification and oral communication skills of bilingual children.

    This paper, through discussion of a teaching intervention at two secondary schools in Hong Kong, demonstrates the learning advancement brought about by group work and dissects the facilitating role of teachers in collaborative discussions. One-hundred and fifty-two Secondary Two (Grade 8) students were divided into three pedagogical groups, namely 'whole-class teaching', 'self-directed group work' and 'teacher-supported group work' groups, and engaged in peer-review, team debate, group presentation and reflection tasks related to a junior secondary science topic (i.e. current electricity). Pre- and post-tests were performed to evaluate students' scientific conceptions, alongside collected written responses and audio-recorded discussions. The results indicate that students achieved greater cognitive growth when they engaged in cooperative learning activities, the interactive and multi-sided argumentative nature of which is considered to apply particularly well to science education and Vygotsky's zone of proximal development framework. Group work learning is also found to be most effective when teachers play a role in navigating students during the joint construction of conceptual knowledge.

    Many adolescents experience sexual harassment and victims of sexual harassment have higher risks regarding well-being and health behaviors such as higher risks of suicidal thoughts, suicidal ideation and feeling unsafe at school. A peer-performed play and school lessons on preventing sexual harassment behavior were presented to secondary school students. We evaluated its effectiveness, using a cluster-randomized controlled design to assign schools to an experimental condition [n = 14 schools; 431 students (51 % female)] and a control condition [n = 11 schools; 384 students (51 % female)]. To measure the effects of the intervention at first post-test and 6-month follow-up, our multilevel analyses used a two-level random intercept model. Outcome measures were sexual harassment behaviors, behavioral determinants and distal factors influencing these behaviors. At post-test, students in the experimental group reported a reduced intention to commit sexual harassment behavior and higher self-efficacy in rejecting it. At post-test and follow-up there was a significant positive effect on social norms for rejecting sexual harassment behavior. At follow-up, sexual self-esteem was higher in students in the experimental group than in the control group. Effects on these determinants will benefit adolescents' future sexual behaviors. In combination, the play and lessons, possibly together with continued sexual health education and skills programs on social-emotional learning in subsequent school years, have potential for preventing sexual harassment behavior.

    The purpose of the study was to determine the effect of a support program on the resilience of female family caregivers of stroke patients. This is a randomized controlled trial. The sample consisted 70 female family caregivers (34 experimental, 36 control group). Data were collected three times (pretest-posttest, follow-up test). Data were collected using the demographical data form, the Family Index of Regenerativity and Adaptation-General. A significant difference was determined between the experimental and control group's follow-up test scores for relative and friend support, social support and family-coping coherence. A significant difference was determined between the experimental group's mean pretest, posttest and follow-up test scores in terms of family strain, relative and friend support, social support, family coping-coherence, family hardiness and family distress. These results suggest that the Support Program contributes to the improvement of the components of resilience of family caregivers of stroke patients. Copyright © 2016 Elsevier Inc.

    To assess the feasibility of a pre-operative occupational therapy intervention for patients undergoing primary total hip replacement. Single blinded feasibility randomised controlled trial, with data collection prior to the intervention, and at 4, 12, and 26 weeks following surgery. Recruitment from two NHS orthopaedic outpatient centres in the West Midlands, UK. Patients awaiting primary total hip replacement due to osteoarthritis were recruited. Following pre-operative assessment, patients were individually randomised to intervention or control by a computer-generated block randomisation algorithm stratified by age and centre. The intervention group received a pre-surgery home visit by an occupational therapist who discussed expectations, assessed home safety, and provided appropriate adaptive equipment. The control group received treatment as usual. The study assessed the feasibility of recruitment procedures, delivery of the intervention, appropriateness of outcome measures and data collection methods. Health related quality of life and resource use were recorded at 4, 12 and 26 weeks. Forty-four participants were recruited, 21 were randomised to the occupational therapy intervention and 23 to usual care. Analysis of 26 week data included 18 participants in the intervention group and 21 in the control. The intervention was delivered successfully with no withdrawals or crossovers; 5/44 were lost to follow-up with further missing data for participation and resource use. The feasibility study provided the information required to conduct a definitive trial. Burden of assessment would need to be addressed. A total of 219 patients would be required in an efficacy trial. © The Author(s) 2015.

    This study examines the effect of communication strategy instruction on EFL students' oral communicative ability and their strategic competence. In a 14-week English as a Foreign Language (EFL) course (English Use II) based on Communicative Language Teaching approach, 80 learners were divided into two groups. The strategy training group ([Formula: see text]) received CS training based on a training program designed for the purpose of the present research, whereas the control group ([Formula: see text]) received only the normal communicative course using Click On 3, with no explicit focus on CSs. The communication strategies targeted in the training program included circumlocution (paraphrase), appeal for help, asking for repetition, clarification request, confirmation request, self-repair, and guessing. Pre- and post-test procedures were used to find out the effect of strategy training on language proficiency and CS use. The effect of the training was assessed by three types of data collection: the participants' pre- and post-IELTS speaking test scores, transcription data from the speaking IELTS test, and 'Click On' Exit Test scores. The findings revealed that participants in the strategy training group significantly outperformed the control group in their IELTS speaking test scores. The results of the post-test transcription data also confirmed that the participants in the strategy training group used more CSs, which could be attributed to the CS training program. The findings of the present research have implications for language teachers, and syllabus designers.

    Sixty-six community-residing elderly (mean age = 72.5) were categorized as depressed (mean = 11.3) or nondepressed (mean = 3.9) based on Beck Depression Inventory scores. After a pre-test battery measuring short-term memory and crystallized/fluid intelligence, the subjects responded to a word association task, disguised as a test of interpersonal empathy, under response dependent or response independent reinforcement conditions, or were assigned to a no treatment control. A post-test battery of alternate forms followed. Four of seven measures showed significant pre- to post-test declines in performance. For two of these four, response dependent reinforcement prevented otherwise significant declines. With pre-test differences statistically controlled, depression produced significant post-test deficits in three measures. Response dependent reinforcement eliminated this depression deficit in one measure. The results indicate that depression may exacerbate fatigue effects for the elderly and response dependent reinforcement may prevent fatigue-caused deficits in short-term memory.

    Full Text Available The study aimed to investigate the influence of the cross-linguistic variation on the construction of boundarycrossing motion events in the translation production of the Turkish speakers of L2 English and to measure the impact of explicit instruction and metalinguistic awareness on the learners’ understanding of typological differences and hence their development of L2 ways of expressing motion events. To this aim, the study followed a pre-test post-test quasi-experimental research design, involving a treatment and a control group. A total of 46 second-year university students participated in the study. They were all majoring in English at the English Language Teaching Department, at a state university in Turkey. The control (18 females and 5 males and the treatment group (14 females and 9 males received a two-week instructional treatment, the first group receiving an implicit instruction, and the second an explicit instruction of the boundary-crossing motion event constructions. Prior to the instructional intervention, a pre-test was administered to the participants. Mann-Whitney U test run on the mean scores obtained from the pre-tests indicated no significant differences between the control and the treatment group, U = 282.5, z = .416, p = .678. Within-group analysis based on post-test results after the termination of the instructional treatment revealed that while the implicit instruction had no effect on learners’ acquisition of motion events, z = 1.842, p = .066., the explicit instruction had a significant effect on L1 Turkish learners’ development of their knowledge of L2-like English patterns in construing motion events. Similarly, between-group analysis revealed that the treatment group (Mdn = 4.00, who received an explicit instruction significantly outperformed the control group (Mdn = 2.00, who received implicit instruction, U = 410.5, z = 3.257, p = .001. The study concluded with the implications of findings for English

    To investigate whether a comprehensive exercise program was effective in improving physical function among institutionalized older adults and whether adding whole-body vibration to the program conferred additional therapeutic benefits. A single-blinded randomized controlled trial was conducted. This study was carried out in residential care units. In total, 73 older adults (40 women, mean age: 82.3 ± 7.3 years) were enrolled into this study. Participants were randomly allocated to one of the three groups: strength and balance program combined with whole-body vibration, strength and balance program without whole-body vibration, and social and recreational activities consisting of upper limb exercises only. All participants completed three training sessions per week for eight weeks. Assessment of mobility, balance, lower limb strength, walking endurance, and self-perceived balance confidence were conducted at baseline and immediately after the eight-week intervention. Incidences of falls requiring medical attention were recorded for one year after the end of the training period. A significant time × group interaction was found for lower limb strength (five-times-sit-to-stand test; P = 0.048), with the exercise-only group showing improvement (pretest: 35.8 ± 16.1 seconds; posttest: 29.0 ± 9.8 seconds), compared with a decline in strength among controls (pretest: 27.1 ± 10.4 seconds; posttest: 28.7 ± 12.3 seconds; P = 0.030). The exercise with whole-body vibration group had a significantly better outcome in balance confidence (pretest: 39.2 ± 29.0; posttest: 48.4 ± 30.6) than the exercise-only group (pretest: 35.9 ± 24.8; posttest: 38.2 ± 26.5; P = 0.033). The exercise program was effective in improving lower limb strength among institutionalized older adults but adding whole-body vibration did not enhance its effect. Whole-body vibration may improve balance confidence without enhancing actual balance performance.

    Groundwater is a crucial topic in education for sustainable development. Nevertheless, international studies with students of different ages have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Building upon international research a multimedia learning program ("Between the raincloud and the tap") was developed. Insights from the fields of conceptual change research, multimedia research, and the Model of Educational Reconstruction were specifically implemented. Two studies were conducted with Austrian pupils (7th grade) and teacher training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge regarding groundwater were determined in a pre- and post-test. The pupils and students greatly profited from independently working through the learning software. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results speak for the fact that theory-guided multimedia learning programs can play an important role in the transfer of research results into the classroom, particularly in science education.
