    Full Text Available Despite numerous reports that active learning increases student understanding, many barriers still exist that prevent faculty from shedding the traditional passive lecture and adopting active learning strategies in the classroom. This study looks at the use of role play as an active learning technique to convey new material, or as reinforcement to traditional lecture. A pre- and post-test survey was utilized to determine student learning gains, along with an anonymous survey to determine student attitudes about role play. Student learning gains are similar regardless of class size, role-playing participation or learning style, and reflect an increase in lower order cognition. Attitudes and learning gains indicate role play is preferable as a reinforcement technique, although the order does not matter if both lecture and role play are utilized to convey information. These data provide insight into the best practices of role-playing implementation in concert with traditional lecture format.

    To evaluate the impact on pharmacy students of a communication course, which used role-playing to develop active-learning skills. Students role-playing pharmacists in patient care scenarios were critiqued by students and pharmacist faculty members. Grading was performed using the rubric inspired by Bruce Berger's Communication Skills for Pharmacists. Written skills were evaluated using student written critique questionnaires. Students completed precourse and postcourse self-assessment surveys. Preceptor evaluations were analyzed for course impact. Students demonstrated improvement in oral skills based on role-play scores (45.87/50) after practice sessions. The average score based on the student questionnaire was 9.31/10. Gain was demonstrated in all defined course objectives. Impact on introductory pharmacy practice experience (IPPE) communication objectives was insignificant. Student evaluations for course and teaching strategy reflected a high average. Study results demonstrated improvement in oral and written communication skills that may help improve interprofessional teamwork between pharmacists and other health care providers.

    2013-05-01

    Full Text Available In this article we discuss how and why role-play supports students in gaining insights into complex leadership situations. We give voice to the students by illustrating their experiences in a role-playing activity involving a human resource management issue designed, performed, and evaluated as part of a management program. The results show that the role-playing supports the students by stimulating them to understand the issue from various perspectives, hence performing an overall change of perspectives. The role-playing exercise also enabled the students to create a collective understanding of the situation. The active social interactions and conversations of role-playing contributed to establishing a sense of community among the students. We argue that role-play could be a viable and forceful pedagogical method whereby teachers give their students the opportunity to prepare for practice. However, to implement role-play as an alternative method of learning requires that the method is a part of the institutional learning space.

    Previous research in Malaysia indicates that there is a problem regarding attitude towards statistics among students. They didn't show positive attitude in affective, cognitive, capability, value, interest and effort aspects although did well in difficulty. This issue should be given substantial attention because students' attitude towards statistics may give impacts on the teaching and learning process of the subject. Teaching statistics using role play is an appropriate attempt to improve attitudes to statistics, to enhance the learning of statistical techniques and statistical thinking, and to increase generic skills. The objectives of the paper are to give an overview on role play in statistics learning and to access the effect of these activities on students' attitude and learning in action research framework. The computer tool entrepreneur role play is conducted in a two-hour tutorial class session of first year students in Faculty of Information Sciences and Technology (FTSM), Universiti Kebangsaan Malaysia, enrolled in Probability and Statistics course. The results show that most students feel that they have enjoyable and great time in the role play. Furthermore, benefits and disadvantages from role play activities were highlighted to complete the review. Role play is expected to serve as an important activities that take into account students' experience, emotions and responses to provide useful information on how to modify student's thinking or behavior to improve learning.

    Studying medicine is hard and it takes longer time compared to other majors. In addition, medical students find medical education boring. It is now necessary to turn medical education into an enjoyable and interesting way. The aim of this study is to evaluate the impact of an educational program related to how to learn taking medical history and how an effective patient-doctor interview should be. The program is structured in various scenarios, on the students learning skills, by the "role playing" method. A scenario prepared by the lecturer was employed in this study. While one of the students acted in a doctor role, the other one played in the role of patient's relative. The lecturer always played in the role of patient. After performing the role playing, students' written and oral feedbacks were gathered. Data were analysed by using SPSS 20.0 program. A total of 470 feedbacks (51.3% were given by the female students) were taken from the students. Thirty-three volunteer students, nineteen of them were male, took part in the role playing. In the patient-doctor interview, the field that students were best were greeting the patients and dealing only with patients during the examination. The mean scores were 3.81±0.95 and 3.79±0.94 respectively. The ability to "summarize" and to "address the patient with his/her name" had the lowest scores; the mean scores of the students in these areas were 2.94±1.11 and 2.70±1.31, respectively. Medical education is a long and tough process. Therefore, it should be interesting, attention getting and cheerful. Role playing can be effective in meeting that need.

    Recent studies of veterinary practice have suggested a correlation between well-developed communication skills and job satisfaction, career retention, customer satisfaction, decreased lawsuits, and financial remuneration for veterinarians. Veterinary educators are under growing pressure to teach functional communication skills to veterinary students; however, the methods employed have not been well evaluated. In this study we have evaluated veterinary student's attitudes to learning communication skills by participating in role play. The study indicates that experiential learning modalities such as role play are perceived as effective by students, despite reluctance to participate and some discomfort surrounding participation.

    Medication communication skills are vital aspects of patient care that may influence treatment outcomes. However, traditional pharmacology curriculum deals with imparting factual information, with little emphasis on patient communication. The current study aims to explore students' perceptions of role-play as an educational tool in acquiring communication skills and to ascertain the need of role-play for their future clinical practice. This questionnaire-based study was done in 2 nd professional MBBS students. A consolidated concept of six training cases, focusing on major communication issues related to medication prescription in pharmacology, were developed for peer-role-play sessions for 2 nd professional MBBS ( n = 122) students. Structured scripts with specific emphasis on prescription medication communication and checklists for feedback were developed. Prevalidated questionnaires measured the quantitative aspects of role-plays in relation to their relevance as teaching-learning tool, perceived benefits of sessions, and their importance for future use. Data analysis was performed using descriptive statistics. The role-play concept was well appreciated and considered an effective means for acquiring medication communication skills. The structured feedback by peers and faculty was well received by many. Over 90% of the students reported immense confidence in communicating therapy details, namely, drug name, purpose, mechanism, dosing details, and precautions. Majority reported a better retention of pharmacology concepts and preferred more such sessions. Most students consider peer-role-play as an indispensable tool to acquire effective communication skills regarding drug therapy. By virtue of providing experiential learning opportunities and its feasibility of implementation, role-play sessions justify inclusion in undergraduate medical curricula.

    Creative arts have been increasingly implemented in medical education. This study investigated the use of interactive theater and role play with professional actors in teaching breaking bad news to medical students. The objectives were to explore the contexts, approaches, experiences, and reactions in giving and receiving bad news. Second-year medical students participated in a required educational session that utilized interactive theater which helps students learn about the issues of breaking bad news to a patient with cancer. Following the interactive theater piece, professional actors provided students role play experiences in small groups with breaking bad news. Anonymous evaluation surveys were given out to all second-year medical students at the conclusion of the breaking bad news session. Surveys contained quantitative and qualitative responses. Three years of evaluations were analyzed. A total of 451 (88 %) students completed the evaluations. Comments were thematically analyzed. Ninety-four percent agreed that the theater piece prompted reflection on patient-provider communications, and 89 % agreed that it stimulated discussion on complex issues with breaking bad news. The two most common themes in student comments concerned the importance of realism in the theater piece, and the value of experiencing multiple perspectives. Use of professional actors during the role play exercises enhances the realism and pushed the students out of their own "comfort zones" in ways that may more closely approximate real life clinical situations. Interactive theater can be a potentially powerful tool to teach breaking bad news during medical school.

    This study used role-play demonstrations to train medical students to communicate drug therapy and evaluated the perceptions on this instructional approach. The second-year medical students who attended a prescription writing session (n = 133), participated in this study. Prescription communication was introduced by using role-play demonstrations. Participant's perceptions were explored by a self-administered questionnaire and focus group discussion. The academic achievement of attendees and nonattendees was compared with an objective structured performance evaluation (OSPE) station that tested students' competence in this skill. Most attendees responded to the questionnaire (81.2%). Almost all respondents expressed their desire to have similar demonstrations in other units. A large proportion of participants reported that role-play demonstrations helped them develop their communication skills, in general, confidence to communicate drug-related information in a prescription, and the ability to explain the aim of drug therapy to patients. Most trainees thought also that they developed skills to communicate instructions on drug use including drug dose, frequency of administration, duration of therapy, adverse drug reactions, and warnings. During the focus group interviews, students thought that role-play was useful but would be more beneficial if conducted frequently in small group as part of the curriculum implementation. The majority of students also reported improved competence in writing a complete prescription. Analysis of attendees and nonattendees grades in the OSPE showed that the former scored higher than the latter group (P = 0.016). Role-play demonstrations were well accepted by medical students and led to the development of their competence in communicating drug therapy to patients.

    Role plays and standardized patients are often used in medical education and have proven to be effective tools for enhancing the communication skills of medical students. Most course concepts need additional time and teaching staff, and there are only a few studies about role plays in the preclinical segment. We developed a highly consolidated concept for the curricular course of 2nd-year medical students, including ten role plays about five subjects: anamnesis, shared decision making, prevention, breaking bad news, and so-called "difficult interactions". Before the course, all students were asked about their expectations and attitudes toward the course. After the course, all students rated the course, their individual learning progress, whether their expectations had been fulfilled, and re-evaluated their attitudes. Questionnaires were self-report measures and had a quantitative and a short qualitative section and were analyzed with descriptive statistics. Group differences (sex, age, role played) were evaluated with t tests at a Bonferonni-corrected significance level of p = .03 and the non-parametric U-tests. Implementing this practical course concept is possible without incurring additional costs. This paper not only shows how that can be done but also provides 5 examples of role scripts for different training subjects. The course concept was highly appreciated by the students. More than 75% felt that they had learned important communication techniques and would be better able to handle difficult situations. Playing the doctor's role was felt to be more useful than playing the patient's role. Women admitted a higher degree of shyness in the beginning and gave higher ratings to their learning progress than men. Students' most frequent wish in the qualitative analysis was to be able to play the doctor's role at least once. The students' answers showed a differentiated pattern, thus suggesting that the influence of social desirability was minimal. Practical skills

    To evaluate the effect of using peer role-playing in learning the communication skills as a step in the development of the communication skills training course delivered to pre-clinical medical students. This study was conducted at the King Abdulaziz University, Jeddah, Saudi Arabia, between September 2014 and February 2015 and comprised medical students. Mixed methods design was used to evaluate the developed communication skills training course. Tests were conducted before and after the communication skills training course to assess the students' self-reported communication. After the course, the students completed a satisfaction survey. Focus groups were conducted to assess the behavioural and organisational changes induced by the course. SPSS 16 was used for data analysis.. Of the293 respondents, 246(84%) were satisfied with the course. Overall, 169(58%) subjects chose the lectures as the most helpful methods for learning the communication skills while 124(42%) considered practical sessions as the most helpful method. Besides, 237(81%) respondents reported that the role-play was beneficial for their learning, while 219(75%) perceived the video-taped role-play as an appropriate method for assessing the communication skills. Peer role-play was found to be a feasible and well-perceived alternative method in facilitating the acquisition of communication skills..

    To develop and evaluate an educational activity designed to teach the adolescent Home, Education and employment, Eating, Activities, Drugs, Sexuality, Suicide/depression, and Safety (HEADS) examination. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Participants were third-year medical students in their pediatric clerkships. Students received an article on the HEADS interview and attended an adolescent medicine educational session. The session included individualized goal-setting and coached role play. Students' skills in doing a HEADS interview were evaluated through a standardized patient encounter (SPE) with a checklist and a retrospective pre- and post-test survey. The SPE checklist was used to assess whether the students included questions in 6 key areas of a HEADS interview. One hundred fifty-two students participated. During the SPE, 90% of students queried the adolescent's home life, 91% education, 82% activities, 84% drug/substance abuse, 95% sexual history, and 61% symptoms of depression. Pre- and postintervention data were compared using the Kruskal-Wallis Test and showed a statistically significant difference in the students' ability to list key topic areas of the HEADS exam (P interview using the HEADS exam (P interview during a SPE. Only three-fifths of the students, however, included questions about symptoms of depression.

    Effective communication and interaction enable nurses to develop caring, empathetic, and respectful relationships with patients and families. However, most nurses feel a lack of preparation in the "soft" skills of communication, professionalism, and leadership. Nurse managers are seeking graduates with strong emotional quotient characteristics such as self-awareness, motivation, self-regulation, empathy, and social skills. Assisting nursing students to develop these intangible, high-level skills presents an ongoing challenge to nurse educators. This creative teaching learning strategy examines the use of psychosocial role-playing skits to enhance nursing student development of the soft skills of nursing. In this strategy, senior level nursing students work in small groups to develop and present realistic 3- to 5-minute skits based on common nurse-patient, nurse-family, or nurse-health care team interactions that incorporate the concepts of therapeutic communication, interpersonal interaction, empathy, active listening, teamwork, delegation, and/or professionalism, followed by a debriefing session. Student feedback suggests that confidence and competence related to the skills of therapeutic communication, interpersonal interaction, empathy, active listening, teamwork, delegation, and professionalism may improve by incorporating soft skill psychosocial role-playing into a nursing education course of study.

    Full Text Available Literature on school refusal has shown a link between school refusal and poor school performance. However, there has been little investigation into the individual underlying factors, and specifically factors directly related to the learning process, such as the learning goals of students and their expectations of success and/or failure. The main purpose of the present study is to investigate the influence of Learned Helplessness (LH and learning goals on school refusal. We hypothesized that LH and learning goals exert a unique role in predicting school refusal above and beyond the roles of academic achievement, age, and gender. The sample consisted of 201 Italian students with an average age of 11.93, with both low (57.2 % of students and high (42.8 % academic achievement. School refusal, LH, and learning goals were measured by means of questionnaires. The results confirm the hypothesis of this study; in fact, we found that learning goals and, above all, LH play a more predictive role of school refusal than academic achievement. These results extend previous studies on school refusal and, for the first time, they provide additional knowledge about this problem, analyzing the relationship between school refusal, learning goals, and LH, still neglected in the literature. Implications on the psychological well-being of students are discussed.

    Full Text Available Speaking is an important skill learned by English student although English covers four skills namely speaking, listening, speaking and writing. Speaking is the main bridge for the students to master English. Unfortunately the fact has shown that the students were quite difficult to improve their speaking skill because they were accustomed to use their native language language in their daily life than using English. The above facts signify that the lecturer should apply the techniques that can motivate students to speak and engage students in encouraging activities. One of the techniques that encourage students to speak is role play. Role play is the choice implemented by the researcher in improving the speaking skill of the first year students at ABA Balikpapan since using role play, the students can express their idea, opinion, and feeling well in their performance without being worried to make mistake. Based on the result of the study, it can be concluded that the result of this research was satisfying. This research claims that it was successful in the effort in improving students’ English speaking skill through Role-Play. Role-Play activity could increase the students’ motivation in joining the teaching and learning activity. Their motivation is reflected in their efforts in preparing the Role-Play.

    Nursing education can maintain its dynamic quality when it moves toward innovation and modern methods of teaching and learning. Therefore, teachers are required to employ up to date methods in their teaching plans. This study evaluated the effects of e-learning, lectures, and role playing on nursing students' learning, retention, and satisfaction. Sixty nursing students were selected as an experiment and control groups during two consecutive semesters. The educational content was presented as e-learning and role playing during one semester (experiment group) and as lectures in the next semester (control group). A questionnaire containing three parts was used to assess demographics, learning and satisfaction statuses. The questionnaire also included a final openended question to evaluate the students' ideas about the whole course. The mean scores of posttest were 16.13 ± 1.37 using role playing, 15.50 ± 1.44 using e-learning and 16.45 ± 1.23 using lectures. The differences between the mean scores of posttest and pretest were 12.84 ± 1.43, 12.56 ± 1.57, and 13.73 ± 1.53 in the mentioned methods, respectively. Lectures resulted in significantly better learning compared to role playing and e-learning. In contrast, retention rates were significantly lower using lectures than using role playing and e-learning. Students' satisfaction from e-learning was significantly lower than lecturing and role playing. Due to the lower rates of retention following lectures, the teachers are recommended to use student- centered approaches in their lectures. Since students' satisfaction with e-learning was lower than the other methods, further studies are suggested to explore the problems of e-learning in Iran.

  17. How Role Play Addresses the Difficulties Students Perceive when Writing Reflectively about the Concepts They are Learning in Science

    Science.gov (United States)

    Millar, Susan

    A fundamental problem which confronts Science teachers is the difficulty many students experience in the construction, understanding and remembering of concepts. This is more likely to occur when teachers adhere to a Transmission model of teaching and learning, and fail to provide students with opportunities to construct their own learning. Social construction, followed by individual reflective writing, enables students to construct their own understanding of concepts and effectively promotes deep learning. This method of constructing knowledge in the classroom is often overlooked by teachers as they either have no knowledge of it, or do not know how to appropriate it for successful teaching in Science. This study identifies the difficulties which students often experience when writing reflectively and offers solutions which are likely to reduce these difficulties. These solutions, and the use of reflective writing itself, challenge the ideology of the Sydney Genre School, which forms the basis of the attempt to deal with literacy in the NSW Science Syllabus. The findings of this investigation support the concept of literacy as the ability to use oral and written language, reading and listening to construct meaning. The investigation demonstrates how structured discussion, role play and reflective writing can be used to this end. While the Sydney Genre School methodology focuses on the structure of genre as a prerequisite for understanding concepts in Science, the findings of this study demonstrate that students can use their own words to discuss and write reflectively as they construct scientific concepts for themselves. Social construction and reflective writing can contribute to the construction of concepts and the development of metacognition in Science. However, students often experience difficulties when writing reflectively about scientific concepts they are learning. In this investigation, students identified these difficulties as an inability to understand

    Acute states of agitation (ASAs) are frequent in daily medical practice. However, training on real ASAs raises technical and ethical issues, whereas lecture-based teaching hardly addresses some educational objectives, e.g., improving relational skills and team-based coordination. Simulation-based medical education (SBME) is a promising medium to train students on managing ASAs. We have recently implemented a role-playing training module on ASAs. In this scenario, four to five students play the role of the staff, while a trained professional actor plays the agitated patient. A subsequent standardized debriefing is conducted by a senior psychiatrist. A first wave of 219 students participated in a one-session training of this ASA module in June 2015. They completed pre-session and post-session questionnaires aiming to collect "proof-of-concept" data. The pre-session questionnaire investigated: previous experience of ASA among students during their clinical training; previous participation in a role-playing SBME; and perceived knowledge of the good practice rules for managing ASAs. The post-session questionnaire investigated among the students if: they thought having been able to appropriately manage the simulated ASA; they found the SBME medium more fitted for training than real situations; they found that the SBME session faithfully reproduced a real ASA; and the session was found useful for transmitting the skills on correct management of ASA. The average level of stress induced by the training was assessed using a numerical rating scale (0-10). Two hundred and six of the 219 students completed the pre-session questionnaire (63% females; response rate 96.7%). A hundred and thirty four students played the scenario and completed the post-session questionnaire (65.7% females; response rate 100%). 38.3% of the responders reported having previously experienced a situation of ASA in their practice, and 31.1% deemed to know the good practices rules for managing an ASA.

    The world is changing significantly, and it is becoming increasingly globalised. This means that countries, businesses, and professionals must think and act globally to be successful. Many individuals, however, are not prepared with the global competency skills needed to communicate and perform effectively in a globalised system. To address this need, higher education institutions are looking for ways to instil these skills in their students. This paper explains one promising approach using current learning principles: transnational interactive online environments in engineering education. In 2011, the TU Dortmund and the University of Virginia initiated a collaboration in which engineering students from both universities took part in one online synchronous course and worked together on global topics. This paper describes how the course was designed and discusses specific research results regarding how interactive online role-playing simulations support students in gaining the global competency skills required to actively participate in today's international workforce.

    Debate and role play for learning critical thinking and communication skills are being increasingly used in various undergraduate medical schools worldwide. We aim to compare students' views about effectiveness of two teaching strategies; debate and role play to exercise critical thinking and communication skills during problem-based learning (PBL). This is a comparative, cross-sectional, and questionnaire-based study. Our subjects were second year undergraduate female medical students enrolled in Imam Abdulrahman Bin Faisal University (IAU), College of Medicine from September 2014-2016, divided into 10 small PBL groups (10-13 students/group/year). Students rated role play and debate as equally effective in improving communication skills. Debate was rated superior to role play in "opening new avenues of thinking" (p-value is 0.01), whereas in "integration of knowledge of basic medical sciences with clinical skills" and "reflection of real life experience" students rated role play being superior to debate (p-value 0.01 and 0.00, respectively). Both role play and debate are well accepted by the students in PBL curriculum as an effective teaching methodology. Both are perceived equally good in improving students' communication skills. Few aspects of critical thinking are improved more by role plays compared to debate and vice versa. © 2018 by The International Union of Biochemistry and Molecular Biology, 2018. © 2018 The International Union of Biochemistry and Molecular Biology.

    The purpose of this study was to examine whether social relationships were associated with sleep status in Chinese undergraduate students. A cross-sectional questionnaire survey was conducted in November 2012 at Huzhou Teachers College, China. The questionnaire involved demographic characteristics, personal lifestyle habits, social relationships and Pittsburgh Sleep Quality Index (PSQI). The associations between social relationships and sleep status were analyzed by using regression models after adjustment for potential factors. Poor sleep quality was prevalent among Chinese undergraduate students. Men tended to have better sleep than women. Lower social stress, better management of stress and good social support were correlated with better sleep status, and stress or support from friends, family and classmates were all related with sleep variables. While only weak associations between number of friends and sleep were detected. The results were consistent in men and women. Educators and instructors should be aware of the importance of social relationships as well as healthy sleep in undergraduates. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available This study investigated the use of the non-scripted role-play activities to improve the oral performance of Thai college students with high and low English proficiency. It attempted to address the following questions: a Do high and low proficiency students perform differently in non-scripted role-play based on scores obtained from pre- and post-tests? If so, how? ; and b Can non-scripted role-play enhance the students’ speaking skills? Which group of students performs better in the non-scripted role-play? The data examined were obtained from tape recorded role-play of 16 non-English-major students (8 each proficiency level during their pre- and post-tests at Yala Rajabhat University in Southern Thailand. The role- play conversations were transcribed and analyzed following the Conversation Analysis (CA framework. The study found that the post test scores of both groups were significantly higher than their pre-test scores at the level of 0.00. The t-test result also revealed that the low proficiency students showed a significant degree of speaking improvement in terms of manner of expression and ability to interact at the level of 0.04 and 0.02 respectively. On the other hand, while improving on the same aspects, the high proficiency students also showed significant improvement in terms of fluency (sig = 0.02. The findings indicated that non- scripted role-play activities helped improve the students’ speaking skills and develop their ability to use the language naturally. Close single-case analyses additionally revealed that despite being traditionally taught conversation lessons with more focus on form and meaning, the participants trained with role-play noticeably improved on the language functions of genuine conversation. It was recommended that role-play activities be used in company with function-focused conversation lessons for the learners’ greater benefits.

    This study aimed to investigate the effects of two educational methods on students' knowledge and performance regarding first aid at emergency scenes. In this semi-experimental study, the sample was selected randomly among male and female public high school students of Isfahan. Each group included 60 students. At first the knowledge and performance of students in first aid at emergency scene was assessed using a researcher-made questionnaire. Then necessary education was provided to the students within 10 sessions of two hours by lecturing and role playing. The students' knowledge and performance was as-sessed again and the results were compared. It was no significant relationship between the frequency distribution of students' age, major and knowledge and performance before the educational course in the two groups. The score of knowledge in performing CPR, using proper way to bandage, immobilizing the injured area, and proper ways of carrying injured person after the education was significantly increased in both groups. Moreover, the performance in proper way to bandage, immobilizing injured area and proper ways of carrying injured person after educational course was significantly higher in playing role group compared to lecturing group after education. Iran is a developing country with a young generation and it is a country with high risk of natural disasters; so, providing necessary education with more effective methods can be effective in reducing mortality and morbidity due to lack of first aid care in crucial moments. Training with playing role is suggested for this purpose.

    The acquirement of basic knowledge of clinical trials and professional attitude in their practices is a general instructional objective in the Model Core Curriculum for Pharmaceutical Education. Unfortunately, the previous program of clinical trial education was not effective in the acquirement of a professional attitude in their practices. Then, we developed the new clinical trial education program using protocol through small group discussion (SGD) and roll-playing. Our program consists of 7 steps of practical training. In step 1, the students find some problems after presentation of the protocol including case and prescription. In step 2, they analyse the extracted problems and share the information obtained in SGD. In steps 3 and 5, five clinical case scenarios are presented to the students and they discuss which case is suitable for entry to the clinical trial or which case corresponds to the discontinuance criteria in the present designed protocol. In steps 4 and 6, the roll-playing is performed by teachers and students as doctors and clinical research coordinators (CRC) respectively. Further, we conducted a trial practice based on this program for the students. In the student's self-evaluation into five grades, the average score of the skill acquisition level in each step was 3.8-4.7 grade. Our clinical trial education program could be effective in educating the candidates for CRC or clinical pharmacists.

    Cooperative learning (CL) and role play are both efficient educational tools for enhancing Chinese student active learning and communication skills. This study was designed to obtain student feedback on the format of CL together with role play in the study of pharmacology in Chinese pharmaceutical undergraduates. CL was used in the self-study of new drugs used clinically but neglected in textbook and class teaching, so that groups of students were assigned to become "specialists" in one area of new drugs. Then, these "specialists" taught their new-found knowledge to other groups in role play approach involving an interaction between the pharmacist and a patient. Student perceptions of CL together with role play were examined using an eight-item survey instrument. Students were satisfied with CL together with role play. Majority of the students believed this teaching method enhanced their learning experience, made them gain more pharmacological expertise, increased the awareness of their career in future and self-educational abilities, and fostered their cooperation spirit and confidence. The materials on CL and role play were also believed pertinent. Only 63.4-76.5% and 63.1-37.3% of the students thought "CL and role-play were very funny" and "I felt very relaxed during CL together with role-play", respectively. CL together with role play is an efficient educational tool for enhancing student active-learning and communication skills. But Chinese students will take some time to adapt to this new teaching method.

    Increasing importance is attached to teaching generic skills to undergraduate students in various disciplines. This article describes an extracurricular, student-led activity for teaching generic skills using the Model United Nations over three months. The activity used the Health Care Simulation Model (HCSM) with peer learning and role-playing to accomplish its objectives. An interview was used to select from undergraduate and postgraduate dental students at Alexandria University, Alexandria, Egypt, to develop a group of staff to act as peer teachers after receiving training (n=77). These peer teachers provided training for 123 undergraduate dental students to serve as delegates who acted as trainees or peer learners. At the end of the training sessions, a conference was held in which the students played the roles of delegates representing officials responsible for health care systems in ten countries. The students reported improvement in generic skills, enjoyed several aspects of the experience, and disliked other aspects of the model to a lesser extent. In multivariate analysis, perceived usefulness of the HCSM was significantly greater for staff than delegates and increased as self-reported improvement in knowledge of health care systems increased. This study suggests that innovative, student-centered educational methods can be effective for teaching generic skills and factual information.

    Clinical skills are an important and necessary part of clinical competence. Simulation plays an important role in many fields of medical education. Although role-playing is common in communication training, there are no reports about the use of student role-plays in the training of technical clinical skills. This article describes an educational intervention with analysis of pre- and post-intervention self-selected student survey evaluations. After one term of skills training, a thorough evaluation showed that the skills-lab training did not seem very realistic nor was it very demanding for trainees. To create a more realistic training situation and to enhance students' involvement, case studies and role-plays with defined roles for students (i.e. intern, senior consultant) were introduced into half of the sessions. Results of the evaluation in the second term showed that sessions with role-playing were rated significantly higher than sessions without role-playing.

    The literature has seen a surge in research on the mental health impacts of technologies such as Facebook, video games, and massively-multiplayer online role-playing games such as World of Warcraft, but little is known regarding the mental health impact of non-video role-playing games, such as Dungeons & Dragons. The present study examines how psychiatrists' perceive role-playing games and whether they play them. Psychiatrists at a tertiary care centre in Canada completed a questionnaire assessing history of playing role-playing games and whether they associate them with psychopathology. Forty-eight psychiatrists responded. Twenty-three percent have played a role-playing game over their lifetimes. Twenty-two percent believed there was an association between psychopathology and role-playing games. A majority of psychiatrists who responded do not associate role-playing games with psychopathology. Implications for clinical practice and future research are discussed.

    During the first phases of adolescent development, young people have little self-efficacy and resistance against substance use. The aim of this study was to demonstrate the effectiveness of role-playing scenarios on the self-efficacy of students in resisting substance use. A pre test and post test study design was used with a single group. The study was carried out with 245 secondary school students. The scenario-based training, developed by the researchers, was presented by the school counselors once a week for 4 weeks. For this purpose, a booklet of scenarios was prepared for the teachers. The role-playing scenarios were intended to improve adolescents' abilities to say "no" to substance offers, to prevent them from becoming addicted to certain substances, and to call for help if needed. The data of the study were collected using the Personal Information Form and the Self-Efficacy for Adolescences Protecting Substance Abuse Scale . The obtained data were assessed using percentages, chi-square, t test, and F test in the SPSS software. Results showed that, after the training, the mean score in the Self-Efficacy for Adolescences Protecting Substance Abuse Scale increased significantly (103.20 ± 20.00) compared with before the training (92.11 ± 17.08) ( P < .05). Short-term outcomes of the class-based scenario training were observed to be effective in the development of students' self-efficacy to resist the temptations of substance use.

    Full Text Available The students often find some problems in practising English speaking. The problem frequently found is that their native language causes them difficult to use the foreign language. Other reason is because of motivation lack to practice the second language in daily conversation. They are also too shy and afraid to take part in the conversation. Many factors can cause the problem of the students’ speaking skills namely the students’ interest, the material, and the media among others including the technique in teaching English. There are many ways that can be done by the students to develop their ability in speaking English. The appropriate technique used by the English teacher also supports their interested in practising their speaking. One of the techniques that can be applied is role play.

    Bullying against nurses is becoming a pervasive problem. In this article, a role play simulation designed for undergraduate nursing students is described. In addition, the evaluation findings from a subsample of students who participated in a role play simulation addressing bullying behaviors are reported. Focus group sessions were completed with a subset of eight students who participated in the intervention. Sessions were audiorecorded, transcribed verbatim, and analyzed using Colaizzi's procedural steps for qualitative analysis. Themes derived from the data were "The Experience of Being Bullied", "Implementation of the Program", "Desired Outcome of the Program", and "Context of Bullying in the Nursing Profession". Role play simulation was an effective and active learning strategy to diffuse education on bullying in nursing practice. Bullying in nursing was identified as a problem worthy of incorporation into the undergraduate nursing curriculum. To further enhance the learning experience with role play simulation, adequate briefing instructions, opportunity to opt out of the role play, and comprehensive debriefing are essential.

    Effective communication among healthcare workers is critically important for patient safety and quality care. The purpose of this pilot study was to evaluate outcomes of a workshop designed to teach Chinese nursing students to use the Situation-Background-Assessment-Recommendation (SBAR) communication tool and examine their attitudes toward utilizing SBAR as a communication tool. A convenience sample of 18 master's degree nursing students at a Chinese university was introduced to SBAR through a workshop. The workshop combined the SBAR tool, video-stimulated recall and role-play case scenarios to illustrate potential positive and negative communication-related patient outcomes. Students completed a 12-item questionnaire before and after participating in the workshop. Four of the items examined the four elements of the SBAR tool (situation, background, assessment, recommendation, score range 0-20), and eight of the items evaluated students' self-perceived attitudes towards utilizing the SBAR tool in their clinical practice (score range 0-40). Pre- and post-workshop scores on the four elements of the SBAR tool demonstrate significant improvement in knowledge of SBAR (14.0±2.9 vs. 16.6±2.2, respectively; p=0.009). Pre- and post-workshop scores on the items testing students' self-perceived abilities also demonstrate significant improvement (26.9±3.5 vs. 32.6±4.5, respectively; p<0.01) in using SBAR. Total scores increased significantly from 40.9±5.0 to 49.2±5.9 (p<0.01). Moreover, 93.8% of the students agreed and strongly agreed that they would use SBAR during clinical practice. Participating in the SBAR workshop in combination with video-stimulated recall and role-play case scenarios significantly improved the Chinese nursing students' knowledge of SBAR and their self-perceived attitudes towards using SBAR tool. Future studies using a larger sample size and longer post-workshop follow-up are needed to confirm the long-term benefits of the workshop. Copyright

    Full Text Available Abstract Background To assess the student perspective on acceptability, realism, and perceived effect of communication training with peer role play (RP and standardised patients (SP. Methods 69 prefinal year students from a large German medical faculty were randomly assigned to one of two groups receiving communication training with RP (N = 34 or SP (N = 35 in the course of their paediatric rotation. In both groups, training addressed major medical and communication problems encountered in the exploration and counselling of parents of sick children. Acceptability and realism of the training as well as perceived effects and applicability for future parent-physician encounters were assessed using six-point Likert scales. Results Both forms of training were highly accepted (RP 5.32 ± .41, SP 5.51 ± .44, n.s.; 6 = very good, 1 = very poor and perceived to be highly realistic (RP 5.60 ± .38, SP 5.53 ± .36, n.s.; 6 = highly realistic, 1 = unrealistic. Regarding perceived effects, participation was seen to be significantly more worthwhile in the SP group (RP 5.17 ± .37, SP 5.50 ± .43; p Conclusions RP and SP represent comparably valuable tools for the training of specific communication skills from the student perspective. Both provide highly realistic training scenarios and warrant inclusion in medical curricula. Given the expense of SP, deciding which method to employ should be carefully weighed up. From the perspective of the students in our study, SP were seen as a more useful and more applicable tool than RP. We discuss the potential of RP to foster a greater empathic appreciation of the patient perspective.

    There has been a rapid growth of online teaching in the past few years, yet the implementation of role-play for formal educational activities in an online setting is growing more slowly. The use of online role-playing for the development of health professions educators is virtually un-documented in the literature. In the project reported here we use role-playing as a method to motivate and increase active participation in an online web-based discussion on community-based medical education (CBME). The Foundation for Advancement of International Medical Education & Research (FAIMER(®) ) Institute hosts virtual group discussions for fellows as part of its fellowship programmes, in order to deepen their knowledge base in health professions education and research. In June 2008, a group of seven FAIMER(®) fellows and faculty members moderated an online discussion on CBME using an online role-play exercise with other fellows and faculty members. Out of a total of 102 fellows, 36 (35.3%) participated actively, which exceeded the typical percentage of list server participation. In addition, a rich discussion resulted in a comprehensive report on the goals, challenges, logistical components, role of Health Ministry policy and the possible ethical mandate of CBME in developing countries. Online role-play encouraged distributed participation among a highly diverse international group of participants, supporting the conclusion that role-playing can be used effectively with mid-career health professional faculty members in the online environment. © Blackwell Publishing Ltd 2011.

    2012-01-01

    Learning and teaching have been conceptualized and executed in many styles, such as self-learning, peer learning, and interaction between the learner and mentor. Today, openness to alternative ideas and embracing innovative approaches in nursing education are encouraged in order to meet students' learning interests and needs, and to address ever-changing healthcare requests. Problem-based learning has been widely adopted in nursing education, with various positive effects on students' learning, such as motivated learning, team work, problem-solving skills and critical thinking. Role-plays have been demonstrated as an effective learning strategy that includes an active and experiential feature that facilitates students' autonomy in their health-related learning. However, there is a lack of discussion of whether and how role-play can be used in problem-based learning (PBL). This paper shows the development of a classroom-based innovation using role-play in the PBL class for higher diploma year-one nurse students (a total of 20 students, five per group). This paper consists of five sections: a) the literature on PBL and nurse education, and role-plays as the innovation; b) the PBL case scenario with the illustration of the two role-play scripts, c) student evaluation on role-play in the PBL class; d) discussions on both achievements and limitations of this innovation, and e) the conclusion. It is hoped that this paper will be an example to other nurse educators who are keen on exploring interactive and student-driven learning and teaching strategies in the PBL class.

    Full Text Available Accounting lesson is considered as a difficult lesson by most students in SMK/SMA. It is even sometimes worse with the less ability of accounting teachers to select learning methods thatcan attract students’ attention and thought. Therefore, it is necessary to find an alternative learning which can help students to involve in the real situation which is fun and memorable. The learning model which can fulfill the fun situation is the role playing. The steps to implement this model in the learning of accounting cycle for trade firm are to divide students in groups and to give each of them an opportunity to play a role. In practice, each student changers the role weekly based on the order. The model makesstuents easier to understand the basic accounting and leads the teachers evaluate the materials if the lack of conformity occurs during the learning.

    Role plays are extremely valuable tools to address different aspects of teaching social responsibility, because they allow students to "live through" complex ethical decision making dilemmas. While role plays are getting high marks from students because their entertainment value is high, their educational value depends on their closeness to students' work experience and the skills of the teacher in helping students comprehend the lessons they are meant to convey.

    The acquisition of knowledge and enhancing skills at actual time requires different approaches, involving students as much as possible, taking advantage of informal learning strengths and opportunities of formal learning. In this perspective, the game seems to be a perfect vehicle, not a single student's playing but a cooperative one. The GeoQuest project consists of an interactive role-playing game which involves all students using a patented system: the "teaching projector". This system allows the interaction of the class group through the use of smartphones and tablets, and it shows in real-time the game progress to the whole class. Our role-playing game is based on three routes at different degrees. The students, divided into several categories (physicist, chemists, disseminators, technicians, historians) have to follow a geological trail in order to discover the present and the past of the Earth. During the path, students have to pass some doors in teamwork; they allow assessment and represent the main sharing/disclosure moment. The doors allow to modulate the activities according to single lesson, teaching unit, module. Main Objectives: Working on PC by themselves, students could be even more alone: it needs a best fitting between ICT and cooperative learning. Role-playing helps students to reach their goals easily through cooperation; this in order to avoid the risk of loneliness of Inquiry Based Science Education, preserving entirely the educational value. Science Research now is based on field expert interaction: the role-playing game categories reflect the necessary team to get their goal. The several roles allow everyone to enhance their own skills. the "teaching projector" allows students to comment and to evaluate the groups activities and route them, providing real-time corrections to everybody. The playing categories represent all the aspects of the research areas: from scientists (physicists, chemists), to technicians, to disseminators and

    Full Text Available Teaching English for non English Department students will be quite a challenge as the students have various background and interest. Handling those students in a big number in a class that requires them to speak is another impending challenge. This is an action research on role-play in English classroom for Information Technology students. This study tries to see whether recorded-role play could maximize students‘ potential in speaking. This study involved 30 students taking English course in Information Technology Faculty. The students were given a situation in which they had to act the role play. They drafted the role -play before they recorded it. The result shows that students felt less tense in acting the role. They also got more time to practice their pronunciation before recording. It even gave students who felt reluctant and shy in the class to actively participate. In addition, students could play around with the supporting background sound to show their creativity. Surprisingly, most students do their best to show their effort in their speaking as the end-product would be played in the classroom, even the most quiet students performed really well. Finally, this recorded-role play proved to be an effective way to maximize students‘ potential in speaking.

    Gaydos, Matthew J.; Squire, Kurt D.

    2012-12-01

    Research has shown that video games can be good for learning, particularly for STEM topics. However, in order for games to be scalable and sustainable, associated research must move beyond considerations of efficacy towards theories that account for classroom ecologies of students and teachers. This study asks how a digital game called Citizen Science, built using tropes and conventions from modern games, might help learners develop identities as citizen scientists within the domain of lake ecology. We conducted an expert-novice study, revealing that games literacy was a mediating variable for content understanding. In a follow-up classroom implementation, games literacy also operated as a variable, although students drove the activity, which mediated this concern. The teacher devised a number of novel pedagogies, such as a field trip, in response to the unit. We found evidence for the most powerful learning occurring through these activities that were reinforced via the curriculum. Students were most engaged by Citizen Science's most "gamelike" features, and learners took up the core ideas of the game. Users also reported the experience was short of commercial gaming experiences, suggesting a tension between game cultures for learning and schools.

    2015-03-01

    This article provides a useful introduction to the art of role-playing in both the individual format and the group format using scripted group role-playing (SGRP). Role-playing can provide powerful learning opportunities, but to do so it must be done well. This article imparts guidance toward this goal. SGRP may greatly enhance the acquisition of critical complex interviewing skills, such as suicide assessment and uncovering domestic violence, in health care providers across all disciplines, an educational goal that has not been achievable to date. Although research is at an early stage of development, the hope represented by SGRP is tangible. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Insight: Exploring Hidden Roles in Collaborative Play

    Directory of Open Access Journals (Sweden)

    Tricia Shi

    2015-06-01

    Full Text Available This paper looks into interaction modes between players in co-located, collaborative games. In particular, hidden traitor games, in which one or more players is secretly working against the group mission, has the effect of increasing paranoia and distrust between players, so this paper looks into the opposite of a hidden traitor – a hidden benefactor. Rather than sabotaging the group mission, the hidden benefactor would help the group achieve the end goal while still having a reason to stay hidden. The paper explores what games with such a role can look like and how the role changes player interactions. Finally, the paper addresses the divide between video game and board game interaction modes; hidden roles are not common within video games, but they are of growing prevalence in board games. This fact, combined with the exploration of hidden benefactors, reveals that hidden roles is a mechanic that video games should develop into in order to match board games’ complexity of player interaction modes.

    Robitaille, Judith; Tousignant-Laflamme, Yannick; Guay, Manon

    2018-03-01

    During their training, musicians must develop good work habits that they will carry on throughout their professional career in order to avoid potential chronic health problems, such as musculoskeletal pain. The effect of sudden changes in instrument playing-time on the development of playing-related musculoskeletal pain (PRMP) has not been thoroughly investigated in music students playing bowed string instruments (BSI), even though they are regularly exposed to such changes to perfect their playing skills. To explore the association between sudden changes in instrument playing-time and changes in PRMP in BSI players. A prospective cohort study was completed with BSI students attending a summer music camp offering high-level training. Participants completed a self-administered 23-item questionnaire designed for the study upon arrival at camp (T1) and then 7 days later (T2). Ninety-three BSI students (16±4 yrs old) completed the questionnaires, for a 23% response rate. Their playing-time increased by 23±14 hrs between T1 and T2. Complaints in pain frequency (e.g., from never to most of the time) and intensity (19±24 mm on VAS) significantly increased between T1 and T2 and were correlated with an increase in playing-time. A sudden increase in playing-time, such as that experienced by elite BSI students attending an intensive music camp, was related to an increase in PRMP. However, in this study, changes in pain characteristics were only partly explained by the change in playing-time.

  15. Time perspective as a predictor of massive multiplayer online role-playing game playing.

    Lukavska, Katerina

    2012-01-01

    This article focuses on the relationship between the time perspective (TP) personality trait and massive multiplayer online role-playing game (MMORPG) playing. We investigate the question of frequency of playing. The TP was measured with Zimbardo's TP Inventory (ZTPI), which includes five factors-past negative, past positive, present hedonistic, present fatalistic, and future. The study used data from 154 MMORPG players. We demonstrated that TP partially explained differences within a group of players with respect to the frequency of playing. Significant positive correlations were found between present factors and the amount of time spent playing MMORPGs, and significant negative correlation was found between the future factor and the time spent playing MMORPGs. Our study also revealed the influence of future-present balance on playing time. Players who scored lower in future-present balance variables (their present score was relatively high compared with their future score) reported higher values in playing time. In contrast to referential studies on TP and drug abuse and gambling, present fatalistic TP was demonstrated to be a stronger predictor of extensive playing than present hedonistic TP, which opened the question of motivation for playing. The advantage of our study compared with other personality-based studies lies in the fact that TP is a stable but malleable personality trait with a direct link to playing behavior. Therefore, TP is a promising conceptual resource for excessive playing therapy.

    Role-playing games have grown and evolved into a large number of forms in the last thirty years, spanning digital as well as non-digital media. They demonstrate a wide variety in the number of participants, style of play and the formal and informal systems that govern them. Despite this diversity...... players at least seem to think they know when something is a role-playing game. Yet there is no commonly accepted definition which both captures games generally accepted as role-playing games and distinguishes them from other, similar, games which begs the question, whether roleplaying games are united...... by anything more than a colloquial name. Additionally, research involving these games is hampered by lack of a widely accepted definition of what constitutes a roleplaying game, as it is then not even possible to clearly delineate the subject of such research.

    2016-04-01

    Full Text Available Role plays have served an instrumental role in social work education by providing opportunities for students to acquire interaction skills. This project tested various online video conferencing tools to facilitate role plays for students who live in different locations and who are unable to be at the same place at the same time. Key features of the technology included the ability to facilitate real-time interaction, compatibility with laptops and Wi-Fi connections, and the ability to record sessions for later viewing and feedback. Method: Case study design. Results: Students were able to use the videoconferencing software with minimal support. Video quality was not always ideal with contributing factors being the time of day students used the software. There were no distinguishable time and effort demands associated with the online video conferencing compared to classroom role plays. Some students found use of the technology caused them to feel disconnected from their peers compared to face-to-face encounters, while other students found the encounter more intimate in that the pressure to perform in front of others was not felt. Implications: Video conferencing is a promising tool to facilitate social work role plays. Future research needs to assess the acquisition of specific skills compared to traditional classroom students.

    The Department of Defense (000) has successfully applied a number of methods for cultural familiarization training ranging from stand-up classroom training, to face-to-face live role-play, to so-called smart-cards. Recent interest has turned to the use of single and mUlti-player gaming technologies to augment these traditional methods of cultural familiarization. One such system, termed CulturePad, has been designed as a game-based role-play environment suitable for use in training and experimentation involving cultural roleplay scenarios. This paper describes the initial CulturePad effort focused on a literature review regarding the use of role-play for cultural training and a feasibility assessment of using a game-mediated environment for role-play. A small-scale pilot involving cultural experts was conducted to collect qualitative behavioral data comparing live role-play to game-mediated role-play in a multiplayer gaming engine.

  12. The Role of Play in Children’s Palliative Care

    Directory of Open Access Journals (Sweden)

    Sue Boucher

    2014-10-01

    Full Text Available Play is the universal language of childhood and the time and opportunity to play is every child’s right. The role of play as a vehicle for communication, a tool for distraction and its value in the holistic development of a normal child is without dispute. The role and value of play increase proportionately when a child is made more vulnerable through illness or disability. Despite this, providing time and opportunities to play can be overlooked or considered to be of little importance or relevance when the focus of the adult carers is the amelioration of clinical symptoms of the illness and on lessening the psychological impact the illness may have on the child. This paper outlines the role and the value of play as an integral component in the provision of palliative care for children with chronic, life-threatening and life-limiting conditions. It will show how providing appropriate equipment, sufficient time and relevant play opportunities not only improves the very sick child’s psychological wellbeing, but also allows the child to cast aside the confines and restrictions imposed upon them by their illness and for a few golden moments to be nothing more than a child at play.

  13. Using dramatic role-play to develop emotional aptitude

    Directory of Open Access Journals (Sweden)

    Russell Dinapoli

    2009-12-01

    Full Text Available As university educators, we need to prepare students for the transition from the information age to what Daniel H. Pink (2005 calls the conceptual age, which is governed by artistry, empathy and emotion, by including in the curricula activities that stimulate both hemispheres of the brain. This can be done by promoting activities that energize what Daniel Goleman (1995 refers to as emotional intelligence, and it further maintains that, as Paul Ekman (2003 suggests, the ability to detect feelings improves communication. Recognizing the need to include in the curricula procedures that help develop students’ right brain aptitudes and enhance their communication skills, I have endeavoured to introduce dramatic scene study as a sustained activity in my English for Specific Purposes courses at the Universidad de Valencia. My aim was to energize the students’ creative and emotional aptitudes, as well as to dynamize effective teamwork. This article sustains that dramatic role-play, based on scripted scene study and related improvisational activities, is one way of achieving this.

    2002-01-01

    This study compared the reports of satanic, sexual, and physical abuse of persons instructed to role-play either dissociative identity disorder (DID) (n = 33), major depression (n = 33), or a college student who experienced minor adjustment problems ("normal") (n = 33) across a number of trials that included role-played hypnosis. As hypothesized, more of the participants who were asked to role-play DID reported at least one instance of satanic ritual abuse and sexual abuse compared with those who role-played depression or a college student with minor adjustment problems. DID role-players reported more incidents of sexual abuse and more severe physical and sexual abuse than did the major depression role-players. Further, the DID role-players differed from the normal role-players on all the measures of frequency and severity of physical and sexual abuse. Participants in all groups reported more frequent and severe incidents of physical abuse after role-played hypnosis than they did prior to it.

    2016-01-01

    Objectives: Medication communication skills are vital aspects of patient care that may influence treatment outcomes. However, traditional pharmacology curriculum deals with imparting factual information, with little emphasis on patient communication. The current study aims to explore students’ perceptions of role-play as an educational tool in acquiring communication skills and to ascertain the need of role-play for their future clinical practice. Materials and Methods: This questionnaire-based study was done in 2nd professional MBBS students. A consolidated concept of six training cases, focusing on major communication issues related to medication prescription in pharmacology, were developed for peer-role-play sessions for 2nd professional MBBS (n = 122) students. Structured scripts with specific emphasis on prescription medication communication and checklists for feedback were developed. Prevalidated questionnaires measured the quantitative aspects of role-plays in relation to their relevance as teaching–learning tool, perceived benefits of sessions, and their importance for future use. Statistical Analysis: Data analysis was performed using descriptive statistics. Results: The role-play concept was well appreciated and considered an effective means for acquiring medication communication skills. The structured feedback by peers and faculty was well received by many. Over 90% of the students reported immense confidence in communicating therapy details, namely, drug name, purpose, mechanism, dosing details, and precautions. Majority reported a better retention of pharmacology concepts and preferred more such sessions. Conclusions: Most students consider peer-role-play as an indispensable tool to acquire effective communication skills regarding drug therapy. By virtue of providing experiential learning opportunities and its feasibility of implementation, role-play sessions justify inclusion in undergraduate medical curricula. PMID:28031605

    2014-06-01

    Most research studies investigating the prevalence of musculoskeletal disorders affecting musicians and music students have focused on classical music, while less is known about their prevalence in other music genres. The purpose of this study was to document cumulative and point prevalence of playing-related musculoskeletal disorders (PRMD) among music students in Iceland and, specifically, to identify differences between those studying classical vs rhythmic music. We hypothesized that students of classical music would report more frequent and more severe musculoskeletal disorders than students involved in rhythmic music, as classical instruments and composition typically require more demanding, sustained postures during practice and performance. A total of 74 students from two classical music schools (schools A and B) and 1 rhythmic school (school C) participated in the study by answering a questionnaire assessing PRMDs. The results showed that 62% of participants had, at some point in their musical career, suffered a PRMD. The cumulative prevalence was highest in music school A (71.4%) and lowest in music school C (38.9%). A statistically significant difference was identified between the cumulative prevalence of PRMD from schools A and B combined compared to music school C (p=0.019). Over 40% of participants reported a "current PRMD," and a significant difference was identified between the three schools (p=0.011), with the highest point prevalence being registered in music school A (66.6%) and the lowest in music school C (22.2%). The prevalence of PRMDs among Icelandic music students was high. The difference found between students who play classical vs rhythmic music may be explained by different demands of the instruments and composition on playing posture.

    2007-08-01

    To date, most research into massively multiplayer online role-playing games (MMORPGs) has examined the demographics of play. This study explored the social interactions that occur both within and outside of MMORPGs. The sample consisted of 912 self-selected MMORPG players from 45 countries. MMORPGs were found to be highly socially interactive environments providing the opportunity to create strong friendships and emotional relationships. The study demonstrated that the social interactions in online gaming form a considerable element in the enjoyment of playing. The study showed MMORPGs can be extremely social games, with high percentages of gamers making life-long friends and partners. It was concluded that virtual gaming may allow players to express themselves in ways they may not feel comfortable doing in real life because of their appearance, gender, sexuality, and/or age. MMORPGs also offer a place where teamwork, encouragement, and fun can be experienced.

    2012-09-01

    Recently, there have been growing concerns about excessive online gaming. Playing Massively Multiplayer Online Role-Playing Games (MMORPGs) appears to be particularly problematic, because these games require a high degree of commitment and time investment from the players to the detriment of occupational, social, and other recreational activities and relations. A number of gaming motives have been linked to excessive online gaming in adolescents and young adults. We assessed 175 current MMORPG players and 90 nonplayers using a Web-based questionnaire regarding their gaming behavior, problems as consequences of gaming, and game motivations and tested their statistical associations. Results indicated that (a) MMORPG players are significantly more likely to experience gaming-related problems relative to nonplayers, and that (b) the gaming motivations escapism and mechanics significantly predicted excessive gaming and appeared as stronger predictors than time investment in game. The findings support the necessity of using measures that distinguish between different types of online games. In addition, this study proves useful regarding the current discussion on establishing (online) gaming addiction as a diagnosis in future categorizations of psychopathology.

  6. NHE8 plays important roles in gastric mucosal protection

    2013-01-01

    Sodium/hydrogen exchanger (NHE) 8 is an apically expressed membrane protein in the intestinal epithelial cells. It plays important roles in sodium absorption and bicarbonate secretion in the intestine. Although NHE8 mRNA has been detected in the stomach, the precise location and physiological role of NHE8 in the gastric glands remain unclear. In the current study, we successfully detected the expression of NHE8 in the glandular region of the stomach by Western blotting and located NHE8 protein at the apical membrane in the surface mucous cells by a confocal microscopic method. We also identified the expression of downregulated-in-adenoma (DRA) in the surface mucous cells in the stomach. Using NHE8−/− mice, we found that NHE8 plays little or no role in basal gastric acid production, yet NHE8−/− mice have reduced gastric mucosal surface pH and higher incidence of developing gastric ulcer. DRA expression was reduced significantly in the stomach in NHE8−/− mice. The propensity for gastric ulcer, reduced mucosal surface pH, and low DRA expression suggest that NHE8 is indirectly involved in gastric bicarbonate secretion and gastric mucosal protection.

    Platelet derived growth factor (PDGF) plays a pivotal role in the remodeling of connective tissues. Emerging data indicate the distinctive role of PDGF receptor-α (PDGFRα) in this process. In the present study, the Pdgfra gene was systemically inactivated in adult mouse (α-KO mouse), and the role of PDGFRα was examined in the subcutaneously implanted sponge matrices. PDGFRα expressed in the fibroblasts of Pdgfra-preserving control mice (Flox mice), was significantly reduced in the sponges in α-KO mice. Neovascularized areas were largely suppressed in the α-KO mice than in the Flox mice, whereas the other parameters related to the blood vessels and endothelial cells were similar. The deposition of collagen and fibronectin and the expression of collagen 1a1 and 3a1 genes were significantly reduced in α-KO mice. There was a significantly decrease in the number and dividing fibroblasts in the α-KO mice, and those of macrophages were similar between the two genotypes. Hepatocyte growth factor (Hgf) gene expression was suppressed in Pdgfra-inactivated fibroblasts and connective tissue. The findings implicate the role of PDGFRα-dependent ECM and HGF production in fibroblasts that promotes the remodeling of connective tissue and suggest that PDGFRα may be a relevant target to regulate connective tissue remodeling.

    Full Text Available The present study examined effects of role-play experience on reading the mind of people with different perception. It is normally difficult but very important in daily life to understand people with different characteristics, including those with restricted color vision. We explored the mechanisms of reading the mind of people with different perception. Forty university students were introduced to a communication task in which the use of mindreading was essential. During each trial, participants viewed a shelf, presented on a laptop computer, which contained several familiar objects, and they were instructed to touch an object on the shelf following an instruction issued by a partner who stood at the opposite side of the shelf. There were two partners: one was a monkey with normal color vision and the other was a dog with restricted color vision. The monkey could see all the objects in the same colors as the participants, whereas the dog saw some objects in different colors (e.g., he saw as yellow objects that the participants saw as red. Participants were required to respond according to the partner's instruction. In the restricted color vision condition, the dog saw the colors of objects differently; thus, participants had to work out his intentions (i.e., mind read, according to his different perspective. In the normal color vision condition, all objects were in the same colors as those seen by the monkey. Before the test phase, the role-play group had a role-play experience in which participants assumed the role of people with restricted color vision. No-role-play participants made significantly more errors in the restricted color vision condition than in the normal color vision condition, whereas among role-play participants, there was no difference between conditions. These results suggest that role-play experience facilitates reading the mind of people with perceptual experiences different from our own.

    Describing the processes underlying play therapy is important for evidence based practice in child therapy. Employing play themes to describe children's play session contents is in widespread use by practitioners, but an adequate classification of these themes for non-directive play therapy practice has not yet been established. This article sets out to fill this gap by first describing how themes can be distinguished and distilled from the contents of play therapy contents. Second, a classification of main themes and sub-themes with exemplars to illustrate these concepts which is compatible with non-directive play therapy practice is set out. Finally a pilot project with experienced play therapists to test this classification in practice is suggested, along with the research questions that will need to be investigated in the shorter and longer terms.

  12. Does genomic imprinting play a role in autoimmunity?

    2011-01-01

    In the 19th century Gregor Mendel defined the laws of genetic inheritance by crossing different types of peas. From these results arose his principle of equivalence: the gene will have the same behaviour whether it is inherited from the mother or the father. Today, several key exceptions to this principle are known, for example sex-linked traits and genes in the mitochondrial genome, whose inheritance patterns are referred to as 'non mendelian'. A third, important exception in mammals is that of genomic imprinting, where transcripts are expressed in a monoallelic fashion from only the maternal or the paternal chromosome. In this chapter, we discuss how parent-of-origin effects and genomic imprinting may play a role in autoimmunity and speculate how imprinted miRNAs may influence the expression of many target autoimmune associated genes.

  13. Galactic Winds and the Role Played by Massive Stars

    Science.gov (United States)

    Heckman, Timothy M.; Thompson, Todd A.

    Galactic winds from star-forming galaxies play at key role in the evolution of galaxies and the intergalactic medium. They transport metals out of galaxies, chemically enriching the intergalactic medium and modifying the chemical evolution of galaxies. They affect the surrounding interstellar and circumgalactic media, thereby influencing the growth of galaxies though gas accretion and star formation. In this contribution we first summarize the physical mechanisms by which the momentum and energy output from a population of massive stars and associated supernovae can drive galactic winds. We use the prototypical example of M 82 to illustrate the multiphase nature of galactic winds. We then describe how the basic properties of galactic winds are derived from the data, and summarize how the properties of galactic winds vary systematically with the properties of the galaxies that launch them. We conclude with a brief discussion of the broad implications of galactic winds.

    Vascular depression in the elderly. Does inflammation play a role?Depression is the most common comorbidity in the elderly, and it is a major determinant of disability. The late-onset depression in highly associated to cardiovascular disease. Depressive symptoms may follow vascular brain damage, especially when mood regulating areas are affected. However depression is strongly associated to vascular disease even when there is no manifest brain damage. Recently great attention has been given to chronic inflammation, both related to depression and vascular disease. Both experimental and clinical evidence shows that a rise in the concentrations of proinflammatory cytokines and glucocorticoids in depressed patients is associated with defect in serotonergic function. Chronic inflammation may underlie many forms of depression associated with vascular disease and metabolic syndrome. The importance of the inflammation hypothesis of depression lies is that psychotropic drugs may have central anti-inflammatory action, and that new generation of central anti-inflammatory drugs may be useful in depression treatment.

    Downstream regulatory element antagonist modulator (DREAM), a transcriptional repressor, is known to modulate pain responses. However, it is unknown whether DREAM is expressed in anucleate platelets and plays a role in thrombogenesis. By using intravital microscopy with DREAM-null mice and their bone marrow chimeras, we demonstrated that both hematopoietic and nonhematopoietic cell DREAMs are required for platelet thrombus formation following laser-induced arteriolar injury. In a FeCl3-induced thrombosis model, we found that compared with wild-type (WT) control and nonhematopoietic DREAM knockout (KO) mice, DREAM KO control and hematopoietic DREAM KO mice showed a significant delay in time to occlusion. Tail bleeding time was prolonged in DREAM KO control mice, but not in WT or DREAM bone marrow chimeric mice. In vivo adoptive transfer experiments further indicated the importance of platelet DREAM in thrombogenesis. We found that DREAM deletion does not alter the ultrastructural features of platelets but significantly impairs platelet aggregation and adenosine triphosphate secretion induced by numerous agonists (collagen-related peptide, adenosine 5′-diphosphate, A23187, thrombin, or U46619). Biochemical studies revealed that platelet DREAM positively regulates phosphoinositide 3-kinase (PI3K) activity during platelet activation. Using DREAM-null platelets and PI3K isoform-specific inhibitors, we observed that platelet DREAM is important for α-granule secretion, Ca2+ mobilization, and aggregation through PI3K class Iβ (PI3K-Iβ). Genetic and pharmacological studies in human megakaryoblastic MEG-01 cells showed that DREAM is important for A23187-induced Ca2+ mobilization and its regulatory function requires Ca2+ binding and PI3K-Iβ activation. These results suggest that platelet DREAM regulates PI3K-Iβ activity and plays an important role during thrombus formation. PMID:27903531

    Although the pattern of BAP1 inactivation in ocular melanoma specimens and in the BAP1 cutaneous/ocular melanoma (CM/OM) predisposition syndrome suggests a tumor suppressor function, the specific role of this gene in the pathogenesis of cutaneous melanoma is not fully understood. We thus set out to characterize BAP1 in cutaneous melanoma and discovered an unexpected pro-survival effect of this protein. Tissue and cell lines analysis showed that BAP1 expression was maintained, rather than lost, in primary melanomas compared to nevi and normal skin. Genetic depletion of BAP1 in melanoma cells reduced proliferation and colony forming capability, induced apoptosis and inhibited melanoma tumor growth in vivo. On the molecular level, suppression of BAP1 led to a concomitant drop in the protein levels of survivin a member of anti-apoptotic proteins and a known mediator of melanoma survival. Restoration of survivin in melanoma cells partially rescued the growth-retarding effects of BAP1 loss. In contrast to melanoma cells, stable overexpression of BAP1 into immortalized but non-transformed melanocytes did suppress proliferation and reduce survivin. Taken together, these studies demonstrate that BAP1 may play a growth-sustaining role in melanoma cells, but that its impact on ubiquitination underpins a complex physiology which is context and cell dependent.

    2014-04-01

    Full Text Available Embryonic development of articular cartilage has not been well understood and the role of doublecortin (DCX in determination of chondrocyte phenotype is unknown. Here, we use a DCX promoter-driven eGFP reporter mouse model to study the dynamic gene expression profiles in mouse embryonic handplates at E12.5 to E13.5 when the condensed mesenchymal cells differentiate into either endochondral chondrocytes or joint interzone cells. Illumina microarray analysis identified a variety of genes that were expressed differentially in the different regions of mouse handplate. The unique expression patterns of many genes were revealed. Cytl1 and 3110032G18RIK were highly expressed in the proximal region of E12.5 handplate and the carpal region of E13.5 handplate, whereas Olfr538, Kctd15, and Cited1 were highly expressed in the distal region of E12.5 and the metacarpal region of E13.5 handplates. There was an increasing gradient of Hrc expression in the proximal to distal direction in E13.5 handplate. Furthermore, when human DCX protein was expressed in human adipose stem cells, collagen II was decreased while aggrecan, matrilin 2, and GDF5 were increased during the 14-day pellet culture. These findings suggest that DCX may play a role in defining chondrocyte phenotype.

    Adolescents as standardized patients are relatively new in medical education. Studies have mostly explored the impact of role playing on adolescents trained to perform standardized patient roles for assessment purposes. No studies were found with regard to the quality of adolescents' role playing. We evaluated the effects of performing a patient role on adolescents trained as simulated patients (SPs) for teaching purposes (in contrast to standardized patients) and evaluated the quality of adolescent SPs' role playing and feedback. Nine young women, aged 16 to 18 years, were trained to portray roles of adolescents asking their general practitioner for an oral contraceptive. Three adolescent men were trained to portray roles of some of the girls' boyfriends. Each role was developed in consultation with the individual adolescent and was largely based on her own personal experience. Students rated the quality of the adolescent SP's role playing and feedback after each SP encounter on a previously validated questionnaire (the Maastricht Assessment of Simulated Patients). Both the adolescent SPs and faculty teachers both completed questionnaires on their experiences. Three hundred forty-one students rated the quality of the SPs' role playing and feedback with a mean score of 7.5 of 10. The faculty teachers were also generally positive about the role playing and feedback. Nevertheless, there were some concerns about the quality of the feedback. Adolescent SPs reported no negative effects because of their performance. Generally, students and teachers were satisfied with the quality of the role playing and feedback provided by the adolescent SPs. The adolescent SPs experienced no negative effects related to their performance, which confirms earlier findings among adolescent standardized patients.

    Full Text Available This paper presents the results of the study of a cohort of college graduate and undergraduate students who participated in playing a Massively Multiplayer Online Role Playing Game (MMORPG as a gameplay rich with social interaction as well as intellectual and aesthetic features. Statistically significant differences among our participants' perception, sensation seeking, and satisfaction in relation to gameplay features are investigated. Our primary objective in this investigation was to look for certain aspects of game playing and sensation seeking that attracts a group of students to engage in long term gameplay online. Results support the majority of pre-planned hypotheses and show potential important considerations to take into account when developing gamified content for educational applications. Furthermore, the limitation of the data used in this study is presented and future directions to remove the current limitation and proliferate results through qualitative research into players' in-game social interactions. We suggest that finding similarities and underlying patterns of attraction among a diverse group of students could be beneficial in designing gameplay features to enhance student participation in the learning experience and improve learning performance.

    Objective To evaluate the role of copy number abnormalities detectable by chromosomal microarray (CMA) testing in patients with epilepsy at a tertiary care center. Methods We identified patients with ICD-9 codes for epilepsy or seizures and clinical CMA testing performed between October 2006 and February 2011 at Boston Children’s Hospital. We reviewed medical records and included patients meeting criteria for epilepsy. We phenotypically characterized patients with epilepsy-associated abnormalities on CMA. Results Of 973 patients who had CMA and ICD-9 codes for epilepsy or seizures, 805 patients satisfied criteria for epilepsy. We observed 437 copy number variants (CNVs) in 323 patients (1–4 per patient), including 185 (42%) deletions and 252 (58%) duplications. Forty (9%) were confirmed de novo, 186 (43%) were inherited, and parental data were unavailable for 211 (48%). Excluding full chromosome trisomies, CNV size ranged from 18 kb to 142 Mb, and 34% were over 500 kb. In at least 40 cases (5%), the epilepsy phenotype was explained by a CNV, including 29 patients with epilepsy-associated syndromes and 11 with likely disease-associated CNVs involving epilepsy genes or “hotspots.” We observed numerous recurrent CNVs including 10 involving loss or gain of Xp22.31, a region described in patients with and without epilepsy. Interpretation Copy number abnormalities play an important role in patients with epilepsy. Given that the diagnostic yield of CMA for epilepsy patients is similar to the yield in autism spectrum disorders and in prenatal diagnosis, for which published guidelines recommend testing with CMA, we recommend the implementation of CMA in the evaluation of unexplained epilepsy.

  7. Integration of simulations and visualizations into classroom contexts through role playing

    While simulations create a novel way to engage students, the idea of numerical modeling may be overwhelming to a wide swath of students - particularly non-geoscience majors or those students early in their earth science education. Yet even for these students, simulations and visualizations remain a powerful way to explore concepts and take ownership over their learning. One approach to bring these tools into the classroom is to introduce them as a component of a larger role-playing activity. I present two specific examples of how I have done this within a general education course broadly focused on water resources sustainability. In the first example, we have created an online multi-player watershed management game where players make management decisions for their individual farms, which in turn set the parameters for a watershed-scale groundwater model that continuously runs in the background. Through the simulation students were able to influence the behavior of the environment and see feedbacks on their individual land within the game. Though the original intent was to focus student learning on the hydrologic aspects of the watershed behavior, I have found that the value of the simulation is actually in allowing students to become immersed in a way that enables deep conversations about topics ranging from environmental policy to social justice. The second example presents an overview of a role playing activity focused on a multi-party negotiation of water rights in the Klamath watershed. In this case each student takes on a different role in the negotiation (e.g., farmer, energy producer, government, environmental advocate, etc.) and is presented with a rich set of data tying environmental and economic factors to the operation of reservoirs. In this case the simulation model is very simple, i.e., a mass balance calculator that students use to predict the consequences of their management decisions. The simplicity of the simulator, however, allows for

  8. Sex Differences in Depression: Does Inflammation Play a Role?

    Women become depressed more frequently than men, a consistent pattern across cultures. Inflammation plays a key role in initiating depression among a subset of individuals, and depression also has inflammatory consequences. Notably, women experience higher levels of inflammation and greater autoimmune disease risk compared to men. In the current review, we explore the bidirectional relationship between inflammation and depression and describe how this link may be particularly relevant for women. Compared to men, women may be more vulnerable to inflammation-induced mood and behavior changes. For example, transient elevations in inflammation prompt greater feelings of loneliness and social disconnection for women than for men, which can contribute to the onset of depression. Women also appear to be disproportionately affected by several factors that elevate inflammation, including prior depression, somatic symptomatology, interpersonal stressors, childhood adversity, obesity, and physical inactivity. Relationship distress and obesity, both of which elevate depression risk, are also more strongly tied to inflammation for women than for men. Taken together, these findings suggest that women's susceptibility to inflammation and its mood effects may contribute to sex differences in depression. Depression continues to be a leading cause of disability worldwide, with women experiencing greater risk than men. Due to the depression-inflammation connection, these patterns may promote additional health risks for women. Considering the impact of inflammation on women's mental health may foster a better understanding of sex differences in depression, as well as the selection of effective depression treatments.

  9. Negative ratings play a positive role in information filtering

    The explosive growth of information asks for advanced information filtering techniques to solve the so-called information overload problem. A promising way is the recommender system which analyzes the historical records of users’ activities and accordingly provides personalized recommendations. Most recommender systems can be represented by user-object bipartite networks where users can evaluate and vote for objects, and ratings such as “dislike” and “I hate it” are treated straightforwardly as negative factors or are completely ignored in traditional approaches. Applying a local diffusion algorithm on three benchmark data sets, MovieLens, Netflix and Amazon, our study arrives at a very surprising result, namely the negative ratings may play a positive role especially for very sparse data sets. In-depth analysis at the microscopic level indicates that the negative ratings from less active users to less popular objects could probably have positive impacts on the recommendations, while the ones connecting active users and popular objects mostly should be treated negatively. We finally outline the significant relevance of our results to the two long-term challenges in information filtering: the sparsity problem and the cold-start problem.

    The study investigated the "differential effect of role-playing enactments" hypothesis through self-evaluations of improvement in assertiveness by participants in an assertive training program. Twenty-two nonassertive Israeli students were trained in two groups: mimetic-replications (action modeling, n = 12) and spontaneous (self-produced action, n = 10) role-playing interventions. Comparisons of their scores on the Self-Expression College Scale (CSES) before and after the training showed that both groups significantly improved their self-evaluations, but the mimetic-replication group did better. In particular, this group scored significantly higher on the CSES first factor (the willingness to take risks in situations that involved other, significant persons).

    Full Text Available There is an increasing demand for an interdisciplinary approach in teaching water management. Computer-supported games and role plays offer the potential of creating an environment in which different disciplines come together and in which students are challenged to develop integrated understanding. Two examples are discussed. The River Basin Game is a common-pool resource game in which participants experience the risk of over-abstractions of water in a river basin and learn how this risk relates to the complexity of the system, the conflict between individual and group optimums and the difficulty in achieving good cooperation. The Globalization of Water Role Play makes participants familiar with the global dimension of water management by letting them experience how national governments can integrate considerations of water scarcity and domestic water productivities into decisions on international trade in commodities like food, cotton and bio-energy. The two examples illustrate that play sessions inspire participants to think about the functioning of systems as a whole and to develop good cooperative courses of action, whereby both uncertainties about the system and the presence of different values and perspectives among participants play a role.

    2009-12-01

    The present study evaluated whether virtual reality (VR) can enhance the realism of role plays designed to help college women resist sexual attacks. Sixty-two female undergraduate students were randomly assigned to either the Role Play (RP) or Virtual Role Play (VRP) conditions, which were differentiated only by the use of VR technology in the VRP condition. A multimethod assessment strategy was used to evaluate the effects of VR on the experienced realism of sexually threatening role plays. Realism was assessed by participant self-reports of negative affect and perceptions of realism, direct observation of participants' verbal displays of negative affect during the role plays, and measurements of participant heart rate during the role plays. Results indicated that VR can indeed heighten the realism of sexually threatening role plays. Discussion focuses on issues regarding the use of VR-enhanced role plays for helping college women resist sexual attacks.

    Melatonin is a possible protective agent in postburn gut pathophysiological dynamics. We investigated the role of endogenously-produced versus exogenously-administered melatonin in a major thermal injury rat model with well-characterized gut inflammatory complications. Our rationale is that understanding in vivo melatonin mechanisms in control and inflamed tissues will improve our understanding of its potential as a safe anti-inflammatory/antioxidant therapeutic alternative. Towards this end, we tested the hypothesis that the gut is both a source and a target for melatonin and that mesenteric melatonin plays an anti-inflammatory role following major thermal injury in rats with 3rd degree hot water scald over 30% TBSA. Our methods for assessing the gut as a source of melatonin included plasma melatonin ELISA measurements in systemic and mesenteric circulation as well as rtPCR measurement of jejunum and terminal ileum expression of the melatonin synthesizing enzymes arylalkylamine N-acetyltransferase (AA-NAT) and 5-hydroxyindole-O-methyltransferase (HIOMT) in sham versus day-3 postburn rats. Our melatonin ELISA results revealed that mesenteric circulation has much higher melatonin than systemic circulation and that both mesenteric and systemic melatonin levels are increased three days following major thermal injury. Our rtPCR results complemented the ELISA data in showing that the melatonin synthesizing enzymes AA-NAT and HIOMT are expressed in the ileum and jejunum and that this expression is increased three days following major thermal injury. Interestingly, the rtPCR data also revealed negative feedback by melatonin as exogenous melatonin supplementation at a dose of 7.43 mg (32 micromole/kg), but not 1.86 mg/kg (8 micromole/kg) drastically suppressed AA-NAT mRNA expression. Our methods also included an assessment of the gut as a target for melatonin utilizing computerized immunohistochemical measurements to quantify the effects of exogenous melatonin

  20. Learning through role-playing games: an approach for active learning and teaching

    Directory of Open Access Journals (Sweden)

    Marco Antonio Ferreira Randi

    Full Text Available This study evaluates the use of role-playing games (RPGs as a methodological approach for teaching cellular biology, assessing student satisfaction, learning outcomes, and retention of acquired knowledge. First-year undergraduate medical students at two Brazilian public universities attended either an RPG-based class (RPG group or a lecture (lecture-based group on topics related to cellular biology. Pre- and post-RPG-based class questionnaires were compared to scores in regular exams and in an unannounced test one year later to assess students' attitudes and learning. From the 230 students that attended the RPG classes, 78.4% responded that the RPG-based classes were an effective tool for learning; 55.4% thought that such classes were better than lectures but did not replace them; and 81% responded that they would use this method. The lecture-based group achieved a higher grade in 1 of 14 regular exam questions. In the medium-term evaluation (one year later, the RPG group scored higher in 2 of 12 questions. RPG classes are thus quantitatively as effective as formal lectures, are well accepted by students, and may serve as educational tools, giving students the chance to learn actively and potentially retain the acquired knowledge more efficiently.

  1. The role of play objects and object play in human cognitive evolution and innovation.

    In this contribution, we address a major puzzle in the evolution of human material culture: If maturing individuals just learn their parental generation's material culture, then what is the origin of key innovations as documented in the archeological record? We approach this question by coupling a life-history model of the costs and benefits of experimentation with a niche-construction perspective. Niche-construction theory suggests that the behavior of organisms and their modification of the world around them have important evolutionary ramifications by altering developmental settings and selection pressures. Part of Homo sapiens' niche is the active provisioning of children with play objects - sometimes functional miniatures of adult tools - and the encouragement of object play, such as playful knapping with stones. Our model suggests that salient material culture innovation may occur or be primed in a late childhood or adolescence sweet spot when cognitive and physical abilities are sufficiently mature but before the full onset of the concerns and costs associated with reproduction. We evaluate the model against a series of archeological cases and make suggestions for future research. © 2018 The Authors Evolutionary Anthropology Published by Wiley Periodicals, Inc.

    Abstract In this contribution, we address a major puzzle in the evolution of human material culture: If maturing individuals just learn their parental generation's material culture, then what is the origin of key innovations as documented in the archeological record? We approach this question by coupling a life‐history model of the costs and benefits of experimentation with a niche‐construction perspective. Niche‐construction theory suggests that the behavior of organisms and their modification of the world around them have important evolutionary ramifications by altering developmental settings and selection pressures.

    Climate change, its mitigation, and adaption to its impacts are among the greatest challenges of our times. Despite the importance of societal decisions in determining climate change outcomes, flawed mental models about climate change remain widespread, are often deeply entrenched, and present significant barriers to understanding and decision-making around climate change. Here, we describe two simulation role-playing games that combine active, affective, and analytical learning to enable shifts of deeply held conceptions about climate change. The games, World Climate and Future Climate, use a state-of-the-art decision support simulation, C-ROADS (Climate Rapid Overview and Decision Support) to provide users with immediate feedback on the outcomes of their mitigation strategies at the national level, including global greenhouse gas (GHG) emissions and concentrations, mean temperature changes, sea level rise, and ocean acidification. C-ROADS outcomes are consistent with the atmosphere-ocean general circulation models (AOGCMS), such as those used by the IPCC, but runs in less than one second on ordinary laptops, providing immediate feedback to participants on the consequences of their proposed policies. Both World Climate and Future Climate role-playing games provide immersive, situated learning experiences that motivate active engagement with climate science and policy. In World Climate, participants play the role of United Nations climate treaty negotiators. Participant emissions reductions proposals are continually assessed through interactive exploration of the best available science through C-ROADS. Future Climate focuses on time delays in the climate and energy systems. Participants play the roles of three generations: today's policymakers, today's youth, and 'just born.' The game unfolds in three rounds 25 simulated years apart. In the first round, only today's policymakers make decisions; In the next round, the young become the policymakers and inherit the

    Genetic diseases represent a significant public health challenge in China that will need to be addressed by a correspondingly large number of professional genetic counselors. However, neither an official training program for genetic counseling, nor formal board certification, was available in China before 2015. In 2009, a genetic counseling training program based on role-playing was implemented as a pilot study at the Third Military Medical University to train third-year medical students. Questionnaires on participant attitudes to the program and role-playing were randomly administered to 324 students after they had finished their training. Pre- and post-training instructional tests, focusing on 42 key components of genetic counseling, were administered randomly to 200 participants to assess mastery of each component. Finally, scores in final examinations of 578 participants from 2009 to 2011 were compared to scores obtained by 614 non-participating students from 2006 to 2008 to further assess program efficacy. Both the training program and the instructional strategy of role-playing were accepted by most participants. Students believed that role-playing improved their practice of genetic counseling and medical genetics, enhanced their communication skills, and would likely contribute to future professional performance. The average understanding of 40 of the key points in genetic counseling was significantly improved, and most students approached excellent levels of mastery. Scores in final examinations and the percentages of students scoring above 90 were also significantly elevated. Role-playing is a feasible and effective instructional strategy for training genetic counselors in China as well as in other developing countries.

    Full Text Available In this article we describe and analyze how autonomous learning emerges in third graders' socioaffective practices as reconstructed in written narratives. Results were obtained by analyzing and reflecting on classroom observation, interviews and written narratives done by the students which let us appreciate different behaviors and reactions the students usually went through. This study shows that children are able to recognize and reflect on the causes and consequences of situations thanks to the use of different socialization forms implemented by their parents; those forms help them become aware of their duties and homework. It also makes evident that social interaction, with family as the main contributors, plays an important role in children's development of autonomy.

  16. Could borate have played a role in the RNA World?

    Science.gov (United States)

    Grew, E. S.; Bada, J. L.; Hazen, R. M.

    2012-12-01

    Two scenarios have been proposed for boron to play a critical role in the stabilization of ribose and other sugars in the ribonucleic acid (RNA) World, >3.8 Ga ago. One scenario envisages oligomeric RNA being synthesized in subaerial intermountane desert valleys in which groundwater was enriched in borate from breakdown of tourmaline (Benner et al. 2012 doi: 10.1021/ar200332w). In the alternative scenario, borates are enriched in hydrothermal environments (3.8 Ma as they are today and (2) plate tectonics was the prevailing regime. The postulated non-marine borate deposits would have been associated with continental collision and subduction with volcanism releasing B, whereas in the second scenario, ocean floor caught up in an early phase of subduction is considered a favorable site for borate formation. Because borate deposits are typically ephemeral and poorly preserved, the lack of evidence in the geologic record for these scenarios does not invalidate them. For example, the oldest reported non-marine borate deposits analogous to the type postulated in first scenario are only 20 Ma, but metamorphosed borates of Precambrian age have been interpreted to have non-marine evaporite precursors, the oldest being 2.4-2.1 Ga in the Liaoning-Jilin area, China. The first B minerals so far reported in the geologic record are metamorphic dravite-schorl tourmalines in the 3.7-3.8 Ga Isua supracrustal belt (southern West Greenland), where there is good evidence for seafloor spreading and subduction. The precursors to the Isua tourmalines are reported to include B-bearing marine clay minerals and detrital tourmaline. The relatively high Li contents in zircon from Jack Hills, Australia, have been cited as evidence for the presence of granitic (s. l.) "protocontinental" crust by 4.3 Ga (Ushikuba et al. 2008 doi:10.1016/j.epsl.2008.05.032; Valley et al. 2010 Rec Geol Surv W Aust, 5-7), but the existence of conventional plate tectonics prior to 3.8 Ga remains controversial

    Pain and overuse are common problems for musicians. Up to 80% of professional musicians suffer from playing-related musculoskeletal disorders (PRMD). The prevalence rate in music students is very high as well. Sufficient data on the underlying musculoskeletal dysfunctions however is scarce. Additionally, the self-assessment of health in musicians seems to differ compared to non-musicians, which might influence their attitudes concerning preventive strategies. Evaluation of frequency of PRMD in music students, investigation of signs and symptoms in music students compared to non-music controls, comparison of self-reported health and well-being between the two groups. Prospective, cross-sectional, case control, non-randomized. Other (University volunteers). Music students in comparison to a non-music control group. Musculoskeletal examination and questionnaire of 36 volunteers of a music university and 19 volunteer students of an university of education were analyzed. The total number of musculoskeletal dysfunctions and differences between the student groups were examined. The personal pain and health self-rating were compared between music and non-music students. Eighty one percent of musicians experienced PRMD. Musicians experienced 6.19 pain regions on average compared to 4.31 of non-musicians. Musicians experiencing PRMD reported significantly (PMusic students presented with nearly the double amount (8.39 versus 4.37) of musculoskeletal dysfunctions per person compared to the non-music control group. Nevertheless, musicians significantly (P<0.05) rated their health more positively than the controls. Musicians presented with more pain regions and a higher amount of musculoskeletal dysfunctions. Further studies evaluating the clinical relevance and their role in the development of PRMD are warranted. Screening of musicians for musculoskeletal dysfunction may identify those musicians at increased risk. Early treatment may prevent PRMD in musicians. Additional

    2011-01-01

    Several studies have linked massively multiplayer online role-playing games (MMORPGs) with possible problematic usage or internet addiction. The main goal of the present study was to assess links between motivations to play in MMORPGs and addictive involvement in such types of games. A total of 696 gamers responded to an online survey. Five distinct motivations to play were identified in gamers: achievement, socializing, immersion, relaxing and escaping. Multiple regression analysis revealed that addictive MMORPG use patterns are predicted by achievement, escapism and socializing motives. Gender was also a significant predictor of problematic involvement in MMORPGs. Moreover, addictive MMORPG use positively correlated with the weekly time devoted to playing MMORPGs.

    2017-12-01

    To assess the role of an "empathy sensitizing module" (ESM) in ophthalmology postgraduates in promoting effective empathetic communication. Thirty-nine ophthalmology postgraduates were taught effective empathetic communication using specially designed module, comprising of five illustrative role-plays. We evaluated the impact of the training by (a) self-assessment of empathy quotient by residents using Jefferson Scale of Empathy (JSE scale) before and 6 weeks after ESM training and (b) nonparticipant observation (NPO) by trained faculty in real-life settings over the next 4 months. A peer-validated, self-designed checklist was used for NPO. The change in score was analyzed using Student's paired t -test. The faculty observed the use of empathy in real-life patient encounters of the trainees over the next 6 months. In addition, secondary qualitative data were collected and analyzed to assess the impact of the module on other stakeholders such as the role-playing undergraduate students and core faculty. Pretraining assessment revealed that concept of empathy during patient communication was understood by only 10% students. PostESM training, the self-rated mean empathy score, on JSE, significantly increased from 95.9 to 106.7 (of a maximum of 140). This was also confirmed by a significant improvement in externally rated empathy and soft skills scores (from 29.3 to 39.1; of a maximum of 55) using the NPO tool. Focus group discussion was done on the continued display of empathy by the trainees in real-life situation over 6 months of observation by the faculty. The group agreed that there was a gradual attrition of initial gain in empathy behavior over the observation period of 6 months. The spillover benefits of the training process were observed among the role-playing undergraduates as well. A thematic analysis of their reflections on the process revealed a substantial change with an improved understanding of effective communication. There is a definite scope for

Existing work is limited by the use of correlational designs and is thus unable to make causal inferences or remove self-selection biases from observed results. The recent development of online, socially integrated video games (massively multiplayer online role-playing games [MMORPGs]) has created a new experience for gamers. This randomized, longitudinal study examined the effects of being assigned to play different video game types on game usage, health, well-being, sleep, socializing, and academics. One hundred 18- to 20-year-old participants (73% male; 68% Caucasian) were randomly assigned to play arcade, console, solo computer, or MMORPG games for 1 month. The MMORPG group differed significantly from other groups after 1 month, reporting more hours spent playing, worse health, worse sleep quality, and greater interference in "real-life" socializing and academic work. In contrast, this group also reported greater enjoyment in playing, greater interest in continuing to play, and greater acquisition of new friendships. MMORPGs represent a different gaming experience with different consequences than other types of video games and appear to pose both unique risks and benefits from their use.

  18. A case study of the abductive reasoning processes of pre-service elementary education students in a role playing setting concerning a mock senate hearing on global climate change

    Petty, Michael Eugene

    Science education has a rich history of studies into the impact of analogical reasoning upon researcher and student alike. These have focused on how induction and deduction are utilized in determining the appropriateness of the analogy being scrutinized. Research in artificial intelligence has demonstrated that human cognition cannot be modeled with only inductive and deductive forms of logic. Charles S. Peirce proposed abduction as a form of logic central to the process of inquiry and discovery. This involves reasoning from observation to best explanation or hypothesis. Peirce's Theory of Signs provided the theoretical foundation and a model of abduction developed by Shank and Cunningham from Peirce's theory offered the conceptual basis for the study. This study uses discourse analysis to attempt to understand the abductive reasoning processes of two groups of students as they interpret new information concerning the political and scientific perspective of the Greening Earth Society and the Center for Disease Control in an authentic, undergraduate-level classroom setting. The five students were members of a capstone course in science education for pre-service elementary education majors who had an interest in science education. The entire class was comprised of fourteen students partitioned into five groups for the culminating exercise for the course. Analysis was carried out using journal entries, audiotapes of planning sessions, a brief summary of their understanding, and videotapes of the mock Senate hearings. The results demonstrated that different members of the group arrived at their understanding using different pathways suggested by the model. While some proceeded linearly, others skipped some stages and later came back to find supportive evidence to strengthen their beliefs. The model is useful in understanding their abductive processes and may provide insight into how we might consider the process in the design of future curriculum for elementary science

    2015-01-01

    Many industrialized countries are net importers of embodied energy and emissions, while many developing countries are net exporters. We examine the role of specialization in driving these trade patterns by conducting a spatial index decomposition analysis on the embodied energy in net exports for 41 economies. The results reveal that industrialized countries have generally offshored energy intensive production, which many developing countries specialize in. We find that specialization, on average, makes the biggest contribution, accounting for roughly 50% of a country's embodied energy in net exports. However, other factors, namely energy intensity and the trade balance, combine to make an equally important contribution. In summary, specialization, despite its significant role, is not the only cause of the embodied energy trade patterns observed between industrialized and developing countries. - Highlights: • The embodied energy in net exports is decomposed into three contributors. • The three contributors are intensity, specialization, and the trade balance. • On average, specialization accounts for roughly 50% of embodied energy flows. • The combination of intensity and trade balance effects is equally important.

    An interview elicits personal views on the role of and issues related to the OPEC Fund from one of those responsible for its founding. Hurtado comments that the Fund is not likely to change direction, although it accepts the agricultural and industrial development priorities of recipients. He also notes a weakness in the International Fund for Agricultural Development. A shortfall of income as Member Countries respond to falling oil prices will require some management changes in the future, but he sees greater unity among OPEC and Third World countries as a result of current economic strains. The industrialized world, which has provided only one sixth as much aid as OPEC, could apply its savings from current low import prices to help developing countries. North-South cooperation is cyclical, and he expects the current situation to have a positive effect on cooperation.

  6. Playable stories: Making programming and 3D role-playing game design personally and socially relevant

    Ingram-Goble, Adam

    This is an exploratory design study of a novel system for learning programming and 3D role-playing game design as tools for social change. This study was conducted at two sites. Participants in the study were ages 9-14 and worked for up to 15 hours with the platform to learn how to program and design video games with personally or socially relevant narratives. This first study was successful in that students learned to program a narrative game, and they viewed the social problem framing for the practices as an interesting aspect of the experience. The second study provided illustrative examples of how providing less general structure up-front, afforded players the opportunity to produce the necessary structures as needed for their particular design, and therefore had a richer understanding of what those structures represented. This study demonstrates that not only were participants able to use computational thinking skills such as Boolean and conditional logic, planning, modeling, abstraction, and encapsulation, they were able to bridge these skills to social domains they cared about. In particular, participants created stories about socially relevant topics without to explicit pushes by the instructors. The findings also suggest that the rapid uptake, and successful creation of personally and socially relevant narratives may have been facilitated by close alignment between the conceptual tools represented in the platform, and the domain of 3D role-playing games.

    The few studies directly comparing the methodological approach of peer role play (RP) and standardized patients (SP) for the delivery of communication skills all suggest that both methods are effective. In this study we calculated the costs of both methods (given comparable outcomes) and are the first to generate a differential cost-effectiveness analysis of both methods. Medical students in their prefinal year were randomly assigned to one of two groups receiving communication training in Pediatrics either with RP (N = 34) or 19 individually trained SP (N = 35). In an OSCE with standardized patients using the Calgary-Cambridge Referenced Observation Guide both groups achieved comparable high scores (results published). In this study, corresponding costs were assessed as man-hours resulting from hours of work of SP and tutors. A cost-effectiveness analysis was performed. Cost-effectiveness analysis revealed a major advantage for RP as compared to SP (112 vs. 172 man hours; cost effectiveness ratio .74 vs. .45) at comparable performance levels after training with both methods. While both peer role play and training with standardized patients have their value in medical curricula, RP has a major advantage in terms of cost-effectiveness. This could be taken into account in future decisions.

    This study investigated the association between religion, religiosity, and gambling using a cross-sectional sample of 570 American University of Beirut students, who self-filled an anonymous English questionnaire. About half (55%) were lifetime gamblers, of which 12% screened as problem/pathological gamblers. Controlling for other demographics and lifetime substance use, Christian students (vs. Muslims) had higher odds of lifetime gambling [6.6 (3.6, 12.2)], any strategic gambling [2.7 (1.2, 5.9)], social nonproblem gambling (SNPG) [7.6 (4.6, 12.3)], and problem/pathological gambling (PG) [6.8(1.8, 26.5)]. Students who never/rarely practiced their faith were 3.6 times as likely [95% CI: 1.5, 8.7] to report lifetime gambling, 3.7 times as likely to report SNPG (vs. NG) [95% CI: 1.3, 10.6], and 7 times as likely to screen for PG (vs. NG) [95% CI: 1.8, 27.4]. Decreased religious importance was associated with greater odds of lifetime gambling, SNPG and PG (vs. nongambling). Stronger associations were observed among Muslims. Religion and religiosity seem to play a protective role, particularly among Muslims whose faith strictly prohibits gambling. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

    Social play behavior, abundant in the young of most mammalian species, is thought to be important for social and cognitive development. Social play is highly rewarding, and as such, the expression of social play depends on its pleasurable and motivational properties. Since the motivational properties of social play have only sporadically been investigated, we developed a setup in which rats responded for social play under a progressive ratio schedule of reinforcement. Dopaminergic neurotransmission plays a key role in incentive motivational processes, and both dopamine and noradrenaline have been implicated in the modulation of social play behavior. Therefore, we investigated the role of dopamine and noradrenaline in the motivation for social play. Treatment with the psychostimulant drugs methylphenidate and cocaine increased responding for social play, but suppressed its expression during reinforced play periods. The dopamine reuptake inhibitor GBR-12909 increased responding for social play, but did not affect its expression, whereas the noradrenaline reuptake inhibitor atomoxetine decreased responding for social play as well as its expression. The effects of methylphenidate and cocaine on responding for social play, but not their play-suppressant effects, were blocked by pretreatment with the dopamine receptor antagonist α-flupenthixol. In contrast, pretreatment with the α2-adrenoceptor antagonist RX821002 prevented the play-suppressant effect of methylphenidate, but left its effect on responding for social play unaltered. In sum, the present study introduces a novel method to study the incentive motivational properties of social play behavior in rats. Using this paradigm, we demonstrate dissociable roles for dopamine and noradrenaline in social play behavior: dopamine stimulates the motivation for social play, whereas noradrenaline negatively modulates the motivation for social play behavior and its expression.

    Musicians from a wide range of backgrounds experience playing-related health problems including musculoskeletal disorders, hearing loss, and performance anxiety. Few studies have focused specifically on the health concerns of musicians in Malaysia. This study aimed to investigate playing-related health problems among student musicians at a university in Malaysia as well as their knowledge and awareness of playing-related health problems. Instrumental music students enrolled in undergraduate and post-graduate university music courses (n=98) participated in a self-report online survey which addressed aspects such as educational background, playing experience, knowledge and awareness of musicians' health issues, history of physical problems, lifestyle factors, and prevention and management strategies. Of the total participants, 28.9% reported that they were currently experiencing playing-related pain in a body part, and 46.4% had experienced playing-related pain at some time. More than half (56.7%) felt that they have not received enough information or advice on playing-related health during their current studies. Musicians who experienced playing-related pain, tension, and discomfort reported the main problem sites to be the fingers and hands, arms, neck, and shoulders. The study results demonstrate that Malaysian university music students are affected by similar types of playing-related physical problems as their counterparts around the world. A greater awareness and knowledge of injury prevention and management strategies is needed so that these music students can sustain healthy playing careers.

    • Cysteine is the metabolic precursor of essential biomolecules such as vitamins, cofactors, antioxidants and many defense compounds. The last step of cysteine metabolism is catalysed by O-acetylserine(thiol)lyase (OASTL), which incorporates reduced sulfur into O-acetylserine to produce cysteine. In Arabidopsis thaliana, the main OASTL isoform OAS-A1 and the cytosolic desulfhydrase DES1, which degrades cysteine, contribute to the cytosolic cysteine homeostasis. • Meta-analysis of the transcriptomes of knockout plants for OAS-A1 and for DES1 show a high correlation with the biotic stress series in both cases. • The study of the response of knockout mutants to plant pathogens shows that des1 mutants behave as constitutive systemic acquired resistance mutants, with high resistance to biotrophic and necrotrophic pathogens, salicylic acid accumulation and WRKY54 and PR1 induction, while oas-a1 knockout mutants are more sensitive to biotrophic and necrotrophic pathogens. However, oas-a1 knockout mutants lack the hypersensitive response associated with the effector-triggered immunity elicited by Pseudomonas syringae pv. tomato DC3000 avrRpm1. • Our results highlight the role of cysteine as a crucial metabolite in the plant immune response. © 2011 The Authors.

    Full Text Available The increasing rate of autoimmunity in recent decades cannot be related to only genetic instabilities and disorders. Diet can directly influence our health. Studies have shown that there is a relationship between nutritional elements and alteration in the immune system. Among immune cells, the function of T lymphocyte is important in directing immune response. T CD4+ cells lead other immune cells to respond to pathogens by secreting cytokines. HIV+ patients, who have largely lost their T CD4+ cells, are susceptible to opportunistic infections, which do not normally affect healthy people. It seems that the metabolism of T cells is critical for their differentiation and their consequent functions. After activation, T cells need to undergo clonal expansion, which is a high energy- consuming process. Studies have shown that specific metabolites deprivation or their excess supply affects T CD4+cells subsets differentiation. Abnormal induction of subsets of T CD4+ cells causes some autoimmunity reactions and hyper-sensitivity as well, which may result from imbalance of diet uptake. In this mini-review, we describe the findings about fatty acids, glucose, amino acids, and vitamins, which are effective in determining the fates of T CD4+ cells. These findings may help us uncover the role of diet in autoimmune diseases.

    Cilia are microtubule-based structures that project into the extracellular space. Ciliary defects are associated with several human diseases, including polycystic kidney disease, primary ciliary dyskinesia, left-right axis patterning, hydrocephalus and retinal degeneration. However, the genetic and cellular biological control of ciliogenesis remains poorly understood. The IFT46 is one of the highly conserved intraflagellar transport complex B proteins. In zebrafish, ift46 is expressed in various ciliated tissues such as Kupffer’s vesicle, pronephric ducts, ears and spinal cord. We show that ift46 is localized to the basal body. Knockdown of ift46 gene results in multiple phenotypes associated with various ciliopathies including kidney cysts, pericardial edema and ventral axis curvature. In ift46 morphants, cilia in kidney and spinal canal are shortened and abnormal. Similar ciliary defects are observed in otic vesicles, lateral line hair cells, olfactory pits, but not in Kupffer’s vesicle. To explore the functions of Ift46 during mouse development, we have generated Ift46 knock-out mice. The Ift46 mutants have developmental defects in brain, neural tube and heart. In particular Ift46(−/−) homozygotes displays randomization of the embryo heart looping, which is a hallmark of defective left-right (L/R) axis patterning. Taken together, our results demonstrated that IFT46 has an essential role in vertebrate ciliary development. PMID:25722189

    Tinnitus impairs quality of life of about 1-2% of the whole population. In most severe situation, tinnitus may cause social isolation, depression and suicide. Drug treatments for tinnitus are generally ineffective, and the mechanisms of tinnitus are still undetermined. Accumulating evidence suggests that tinnitus is related to changes of widespread brain networks. Recent studies propose that paraflocculus (PFL), which is indirectly connected to various cortical regions, may be a gating zone of tinnitus. So we examined the electrophysiological changes and neurotransmitter alterations of the PFL in a rat model of sodium salicylate (SS)-induced tinnitus. We found that spontaneous firing rate (SFR) of the putative excitatory interneurons of the PFL was significantly increased. The level of glutamic acid, which is the main excitatory neurotransmitter in the nervous system, was also dramatically increased in the PFL after SS treatment. These results confirmed the hyperactivity of PFL in the rats with SS-treatment, which might be due to the increased glutamic acid. Then we examined the SFR of the auditory cortex (AC), the center for auditory perception, before and after electrical stimulation of the PFL. 71.4% (105/147) of the recorded neurons showed a response to the stimulation of the PFL. The result demonstrated that stimulation of the PFL could modulate the activity of the AC. Our study suggests a role of PFL in SS-induced tinnitus and AC as a potential target of PFL in the process of tinnitus. Copyright © 2017 Elsevier B.V. All rights reserved.

  15. Sleep apps: what role do they play in clinical medicine?

    Lorenz, Christopher P; Williams, Adrian J

    2017-11-01

    Today's smartphones boast more computing power than the Apollo Guidance Computer. Given the ubiquity and popularity of smartphones, are we already carrying around miniaturized sleep labs in our pockets? There is still a lack of validation studies for consumer sleep technologies in general and apps for monitoring sleep in particular. To overcome this gap, multidisciplinary teams are needed that focus on feasibility work at the intersection of software engineering, data science and clinical sleep medicine. To date, no smartphone app for monitoring sleep through movement sensors has been successfully validated against polysomnography, despite the role and validity of actigraphy in sleep medicine having been well established. Missing separation of concerns, not methodology, poses the key limiting factor: The two essential steps in the monitoring process, data collection and scoring, are chained together inside a black box due to the closed nature of consumer devices. This leaves researchers with little room for influence nor can they access raw data. Multidisciplinary teams that wield complete power over the sleep monitoring process are sorely needed.

    Hereditary hemochromatosis (HH) is an iron overload disease that is caused by mutations in HFE, HJV, and several other genes. However, whether HFE-HH and HJV-HH share a common pathway via hepcidin regulation is currently unclear. Recently, some HH patients have been reported to carry concurrent mutations in both the HFE and HJV genes. To dissect the roles and molecular mechanisms of HFE and/or HJV in the pathogenesis of HH, we studied Hfe(-/-), Hjv(-/-), and Hfe(-/-)Hjv(-/-) double-knockout mouse models. Hfe(-/-)Hjv(-/-) mice developed iron overload in multiple organs at levels comparable to Hjv(-/-) mice. After an acute delivery of iron, the expression of hepcidin (i.e., Hamp1 mRNA) was increased in the livers of wild-type and Hfe(-/-) mice, but not in either Hjv(-/-) or Hfe(-/-)Hjv(-/-) mice. Furthermore, iron-induced phosphorylation of Smad1/5/8 was not detected in the livers of Hjv(-/-) or Hfe(-/-)Hjv(-/-) mice. We generated and phenotypically characterized Hfe(-/-)Hjv(-/-) double-knockout mice. In addition, because they faithfully phenocopy clinical HH patients, these mouse models are an invaluable tool for mechanistically dissecting how HFE and HJV regulate hepcidin expression. Based on our results, we conclude that HFE may depend on HJV for transferrin-dependent hepcidin regulation. The presence of residual hepcidin in the absence of HFE suggests either the presence of an unknown regulator (e.g., TFR2) that is synergistic with HJV or that HJV is sufficient to maintain basal levels of hepcidin.

    Mr. Hirofunti Ando, Deputy Executive Director of the UNFPA, delivered the statement of Dr. Nafis Sadik, Executive Director of the UNFPA at the International Meeting of Parliamentarians on Population and Social Development. The International Conference of Parliamentarians on Population and Development (ICPPD) in Cairo in September 1994 made a significant impact on the attitudes and support of parliamentarians regarding population issues. The Asian Forum of Parliamentarians on Population and Development (AFPPD) brought together a group of parliamentarians from all over the world to discuss population issues and social development. The World Summit included in its deliberations the accumulated experiences of earlier international conferences dealing with social economic issues. The ICPD Program of Action addressed concerns relevant to the agenda of the Social Summit: the crucial contribution that early population stabilization will make towards the attainment of sustainable development; the significant role of integrated policies on population and development in creating employment; the importance of population policies and programs in alleviating poverty; the contributions of reproductive health policies, including high-quality family planning services, to the enhancement of the status of women and to the achievement of gender equality; the synergy between education, family planning, and the general improvement of the human condition; and the relationship between population pressures, poverty, and environmental degradation. The ICPD Program of Action also identified critically important population and development objectives, such as ensuring access to education, especially of girls; reducing infant, child, and maternal mortality; and providing universal access to reproductive health and family planning services. Now the challenge is to mobilize the necessary resources for the Social Summit.

    Background & aim: Awareness about the different aspects of health during puberty plays an important role in the health of girls and finally on their health future pregnancy. The aim of the present study was to to compare the effect of role playing and classical training methods in the the improvement of puberty health among secondary school girls in Yasouj City, Iran. Methods: In this study, the educational need during puberty school girls in the interview was determined. The two schools girls were randomly selected (students any school-60. Next, a knowledge and attitude questionnaire and a behavior checklist related to the main puberty health problems were completed. Then one of the schools randomly was selected as educational interventions schools and other were studied as controls. After grouping the students into four groups of 15, intervention were conducted in four sessions including: role-play, question and answer, and lecture.

    2009-11-01

    Massive multiplayer online role-playing games (MMORPGs) are very popular in China, which provides a potential platform for scientific research. We study the online-offline activities of avatars in an MMORPG to understand their game-playing behavior. The statistical analysis unveils that the active avatars can be classified into three types. The avatars of the first type are owned by game cheaters who go online and offline in preset time intervals with the online duration distributions dominated by pulses. The second type of avatars is characterized by a Weibull distribution in the online durations, which is confirmed by statistical tests. The distributions of online durations of the remaining individual avatars differ from the above two types and cannot be described by a simple form. These findings have potential applications in the game industry.

    Full Text Available Can the use of a method such as role play help reduce sexual risk behaviour among KwaZulu-Natal learners? A study was undertaken of the use of role plays by Grade 8 learners, at eight urban and rural KwaZulu-Natal high schools, as part of a programme to reduce the prevalence of teenage pregnancy. Within the framework of Bandura's Social Cognitive Theory, learners participated in role plays covering five topics - choice, self-respect and emotional abuse; partner coercion/negotiation about having sex; visiting the clinic for contraception; perceived and purchasing value of the child support grant; and testing for HIV. We report on the organisation, implementation and evaluation of the role plays. Data from facilitators, educators and learners were triangulated and suggest that role play has potential for building self-efficacy among learners with respect to sexual behaviour.

    2015-09-01

    The current study examined the severity of playing-related pain (PRP) problems among music students at the Prague State Conservatoire, as well as the various treatment methods used by these students and how they approach and deal with these phenomena while studying. In total, 180 instrumental students participated and completed a paper questionnaire. Of these, 88.9% reported that they had experienced PRP at least once in their lives, with 12.6% experiencing pain every time they play. The onset of PRP seemed to coincide with the transition period on entry to the conservatoire and was associated with the increase in hours of practice. Specific body regions associated with playing each particular instrument were most frequently affected, with females being more susceptible than males to the development of PRP. An alarming 35% of the affected students tended not to seek help at all, whereas those who did tended to seek advice first from their instrument tutor and second from medical doctors. Most students who visited doctors reported that medical treatments only partially helped them to overcome PRP problems. The most frequent treatment methods used were resting, gel or creams, and physical exercises. Students believed that inappropriate posture played a key role in the development of their PRP problems. Finally, students indicated a willingness to be aware of and educated about PRP issues during their studies. Further exploration of PRP problems among student musicians is warranted. Better understanding of differing attitudes toward, use of, and efficiency of various treatment methods after the occurrence of PRPs will provide additional insight for prevention and treatment.

  6. Sexually dimorphic role for vasopressin in the development of social play

    Directory of Open Access Journals (Sweden)

    Matthew J. Paul

    2014-02-01

    Full Text Available Despite the well-established role of vasopressin (AVP in adult social behavior, its role in social development is relatively unexplored. In this paper, we focus on the most prominent social behavior of juvenile rats, social play. Previous pharmacological experiments in our laboratory suggested that AVP regulates play in a sex- and brain region-specific manner in juvenile rats. Here we investigate the role of specific AVP systems in the emergence of social play. We first characterize the development of play in male and female Wistar rats and then ask whether the development of AVP mRNA expression correlates with the emergence of play. Unexpectedly, play emerged more rapidly in weanling-aged females than in males, resulting in a sex difference opposite of that typically reported for older, juvenile rats. AVP mRNA and play were correlated in males only, with a negative correlation in the bed nucleus of the stria terminalis and a positive correlation in the paraventricular nucleus of the hypothalamus. These findings support the hypothesis that AVP acts differentially on multiple systems in a sex-specific manner to regulate social play and suggest a role for PVN and BNST AVP systems in the development of play. Differential neuropeptide regulation of male and female social development may underlie well-documented sex differences in incidence, progression, and symptom severity of behavioral disorders during development.

    Palagi, Elisabetta

    2009-02-01

    Adult strepsirrhines have been completely neglected in the study of animal play. I focused on adult play fighting and the role of tail-play as a signal in ringtailed lemurs (Lemur catta). Tail-play is performed during play fighting, when lemurs anoint or, more rarely, wave their tails toward the playmate. During the prereproductive period, male and female lemurs engaged in play fighting with comparable frequencies, as was expected to occur in monomorphic species such as L. catta. The dyads showing low aggression rates engaged most frequently in play fighting, and polyadic play was frequently performed. Signals seem to be important in avoiding escalation to real aggression, especially when the playfulness of performers can be misunderstood by recipients. Tail-play was most frequent (a) in the dyads with low grooming rates (low familiarity degree) and (b) during the most risky play sessions (polyadic ones). Thus, tail-play can be considered as a useful tool for play communication in ringtailed lemurs. Copyright 2009 APA, all rights reserved.

    Student evaluation of teaching (SET) is often used in the assessment of faculty members' job performance and promotion and tenure decisions, but debate over this use of student evaluations has centered on the validity, reliability, and application of the data in assessing teaching performance. Additionally, the fear of student criticism has the potential of influencing course content delivery and testing measures. This Point/Counterpoint article reviews the potential utility of and controversy surrounding the use of SETs in the formal assessment of dental school faculty. Viewpoint 1 supports the view that SETs are reliable and should be included in those formal assessments. Proponents of this opinion contend that SETs serve to measure a school's effectiveness in support of its core mission, are valid measures based on feedback from the recipients of educational delivery, and provide formative feedback to improve faculty accountability to the institution. Viewpoint 2 argues that SETs should not be used for promotion and tenure decisions, asserting that higher SET ratings do not correlate with improved student learning. The advocates of this viewpoint contend that faculty members may be influenced to focus on student satisfaction rather than pedagogy, resulting in grade inflation. They also argue that SETs are prone to gender and racial biases and that SET results are frequently misinterpreted by administrators. Low response rates and monotonic response patterns are other factors that compromise the reliability of SETs.

    Full Text Available Almost all environmental problems are caused by human. Besides being good at environmental engineering theory and technology, to enhance the ability to solve environmental problems, the environmental practitioners need a closer understanding of the stance of different stakeholders. This study is an instructional design combining both "case method" and "role-playing" into the “Soil and Groundwater Talent Training Courses” in Taipei. The curriculum is based on the hexavalent chromium pollution case in Yunlin County. Each group of students is encouraged to play four roles, inculding leather factory owners, farmers, environmental officials, and soil testing professionals. Each group of students has to propose solution strategies after discussion and consultation. The study adopts a single group posttest design. The qualitative data were analyzed using content analysis. The quantitative data were analyzed through proportion and Pearson correlation. Results were as follows: (1 The solution strategies identified by the students include: “mutual communication”, “consensus-building”, and “the formation of an environmental committee". (2 More than 80% of students were satisfied with the instruction, and they found it helpful in terms of knowledge and skills in doing surveying. A moderate positive correlation exists between students’ participation and learning satisfaction. A reflection concerning this instruction design along with some recommendations are provided.

    Full Text Available Students with special education needs such as autism tend to have difficulty with appropriate play skills and leisure time skills. A lack of play may lead to inappropriate behaviors such as stereotypy or passivity. When students have a limited community of reinforcers it may be difficult for educators to find motivators that can be used to teach language, social, academics, and other skills. The present study tested a treatment package in a small group format on the on task painting behavior and stereotypy of four boys between 5 and 12 years old having autism. Using a delayed multiple baseline across students experimental design, a functional relationship was demonstrated between an observed increase in on task painting behavior and decrease in stereotypy of all four students as a function of their participation. Limitations of the present study were also discussed.

    The present study examined the effects of role-play experience on children's mindreading ability. Forty-one primary school children (20 boys, 21 girls, mean age: 9.37 years, range: 8-11 years) were introduced to a communication task in which the use of mindreading was essential. During each trial, participants viewed a shelf, presented on a laptop, which contained several familiar objects, and they were instructed to touch an object on the shelf following an order issued by a "manager" who stood at the opposite side of the shelf. There were two managers: one was a monkey manager with normal color vision, and the other was a dog manager with restricted color vision. The monkey manager could see all the objects in the same colors as the participants, whereas the dog manager saw some objects in different colors. Participants were required to respond according to the manager's instruction. In the restricted color vision condition, the dog manager saw the colors of objects differently; thus, participants had to work out his intentions, according to his different perspective. In the normal color vision condition, all objects were in the same colors as those seen by the monkey manager. Before the test phase, participants in the role-play group were provided a role-play experience in which they assumed the role of the dog manager with restricted color vision. The experimental data were analyzed using a 2 × 2 mixed-design ANOVA (role-play condition × communication partner condition) to examine differences in the error rate. Both main effects and its interaction were significant. According to the post-hoc analyses, participants in the no-role-play condition made significantly more errors in the restricted color vision condition than in the normal color vision condition, whereas no such difference was found among participants in the role-play condition. These results suggest that role-play experience could facilitate mindreading of characters with restricted color vision.

    The purpose is to make an appropriate list of terms that describe person's moment-to-moment changes in moods during psychodrama sessions. Seventy nurse students participated in a series of psychodrama sessions, consisting of a session of warming-up and two sessions of role playing. They rated their moods at the beginning of the sessions and after each session, on a five-point scale for each of the 55 terms, which were supposed to cover all kinds of moods during psychodrama sessions. After analyzing variations (using factor analyses) of subjects' ratings, three factors were found to be sufficient for describing their moods, and the terms in the list were eventually reduced to sixteen. Changes of moods analyzed through the ratings of sixteen scales were related significantly with subjects' performances of warming-up and role playing.

    The paper offers a review of the development of the concept of play and playing. The true beginnings of the development of the theories of play are set as late as in the 19th century. It is difficult to define play as such; it may much more easily be defined through its antipode--work. In the beginning, play used to be connected with education; it was not before Freud's theory of psychoanalysis and Piaget's developmental psychology that the importance of play in a child's development began to be explained in more detail. The paper further tackles the role of play in the adult age. Detailed attention is paid to psychodynamic and psychoanalytic authors, in particular D. W. Winnicott and his understanding of playing in the intermediary (transitional) empirical or experiential space. In other words, playing occupies a space and time of its own. The neuroscientific concept of playing is also tackled, in the connection with development as well.

    Role-based learning involves the process whereby learners acquire skills, knowledge and understanding through the assumption of roles within real-life settings. Role-play holds potential as an effective learning strategy for children; however, there is limited research on the use of role-play as a therapy method within the field of speech-language pathology. Children with language learning disability (LLD) typically present with difficulties in social communication, which can negatively affect their social and academic achievement. The aim of this study was to determine the effectiveness of role-play as a therapy approach targeting the pragmatic skills of stylistic variation and requesting for clarification in learners with LLD. The use of combined positivist and interpretivist paradigms allowed for the implementation of an embedded mixed methods design. An experimental pretest-posttest design was implemented. Eight participants, who were learners with a diagnosis of LLD, were purposefully selected. Data collection was conducted over five phases, utilising the Clinical Evaluation of Language Fundamentals (4th Ed.) Pragmatics Profile, discourse completion tasks, session plans and session records. Quantitative data were analysed using descriptive statistics and were supplemented by qualitative data from session records. Results revealed improvements in stylistic variation and requesting for clarification post role-play intervention, with minimal changes in the control group. Limitations of the study have been reported for consideration when interpreting results. Role-play as a therapy approach targeting two pragmatic skills, stylistic variation and requesting for clarification, was found to be beneficial for learners with LLD. Recommendations for the implementation of role-play as a therapy approach were made.

    To meet international goals for climate change mitigation and adaptation, as well as energy access and equity, there is an urgent need to explore and define energy policy paths forward. Despite this need, students, citizens, and decision-makers often hold deeply flawed mental models of the energy and climate systems. Here we describe a simulation role-playing game, World Energy, that provides an immersive learning experience in which participants can create their own path forward for global energy policy and learn about the impact of their policy choices on carbon dioxide emissions, temperature rise, energy supply mix, energy prices, and energy demand. The game puts players in the decision-making roles of advisors to the United Nations Sustainable Energy for All Initiative (drawn from international leaders from industry, governments, intergovernmental organizations, and citizens groups) and, using a state-of-the-art decision-support simulator, asks them to negotiate a plan for global energy policy. We use the En-ROADS (Energy Rapid Overview and Decision Support) simulator, which runs on a laptop computer in <0.1 sec. En-ROADS enables users to specify many factors, including R&D-driven cost reductions in fossil fuel-based, renewable, or carbon-neutral energy technologies; taxes and subsidies for different energy sources; performance standards and energy efficiency; emissions prices; policies to address other greenhouse gas emissions (e.g., methane, nitrous oxide, chlorofluorocarbons, etc.); and assumptions about GDP and population. In World Energy, participants must balance climate change mitigation goals with equity, prices and access to energy, and the political feasibility of policies. Initial results indicate participants gain insights into the dynamics of the energy and climate systems and greater understanding of the potential impacts policies.

  1. The games economists play: Why economics students behave more selfishly than other students.

    Directory of Open Access Journals (Sweden)

    Philipp Gerlach

    Full Text Available Do economics students behave more selfishly than other students? Experiments involving monetary allocations suggest so. This article investigates the underlying motives for the economic students' more selfish behavior by separating three potential explanatory mechanisms: economics students are less concerned with fairness when making allocation decisions; have a different notion of what is fair in allocations; or are more skeptical about other people's allocations, which in turn makes them less willing to comply with a shared fairness norm. The three mechanisms were tested by inviting students from various disciplines to participate in a relatively novel experimental game and asking all participants to give reasons for their choices. Compared with students of other disciplines, economics students were about equally likely to mention fairness in their comments; had a similar notion of what was fair in the situation; however, they expected lower offers, made lower offers, and were less willing to enforce compliance with a fair allocation at a cost to themselves. The economics students' lower expectations mediated their allocation decisions, suggesting that economics students behaved more selfishly because they expected others not to comply with the shared fairness norm.

    Full Text Available Online narrative (fiction-based role-playing games and massively multiplayer online role-playing games (MMORPGs provide a ludic structure in which role players enact the gender and sexuality of their avatars. To investigate how role players perceive and perform their avatars' gender and sexuality in online games, I invited role players from MMORPGs and narrative RPGs to participate in an online survey. This study examines how the online game environment mediates players' self-expression and their acceptance of minority identities. Qualitative analysis of the data collected suggests that players who demonstrate empathy with and examination of their avatars' genders and sexualities, and who experience a sense of belonging within the game structure, are able to form positive interpersonal relationships that allow them to accept others' expressed identities.

    Full Text Available Abstract. Uncertainty in the nation's economy, the impact of globalization as well as various crises and disasters are problems that may lead to national disintegration which make few groups want to secede from NKRI. All these problems unilaterally are evidences of the unreliability of civic education learning as a subject that mandates to maintain the integrity of NKRI, not in the macro scope but in giving civic education as early as possible from the elementary school. The learning outcomes of civic education learning do not only include the acquisition of knowledge, but more to the acquisition of feeling and behavior. Consequently, in the pre-cycle, the researcher found difficulties to integrate the two domains, which made the learning outcomes below the mini-mum mastery criteria, students’ behavior lacking the feeling of love to their homeland and stu-dents’ motivation in learning low. To solve the problems, the researcher used role play method and as a result, after two cycles, students’ learning outcomes increased. The percentage of stu-dents’ minimum mastery criteria increased from 52% (score 75 to 69% in cycle I and 96% in cycle II. In addition, the students’ were more motivated in learning, followed ceremony in an or-derly manner, and behaved in ways that reflect the love of homeland. It can be concluded that ap-plying role play method in the lesson of preserving the integrity of NKRI at Grade V SDN Cilengkrang North Sumedang Regencey, students’ learning outcomes could be improved.

    To evaluate the impact of current and prior video game playing on initial robotic simulation skill acquisition. This cross-sectional descriptive study (Canadian Task Force Classification II-1) was conducted at a medical university training center. The study subjects were medical students who currently played video games (Group I) and those who had not played video games in the last 2 years (Group II). The robotic skills of both groups were assessed using simulation. Twenty-two students enrolled in this study; however, only 21 completed it. The median age of the participants was 23 (22-24) years and 24 (23-26) years in Groups I and II, respectively. Among the participants, 15 (71.4%) were male and 6 (28.5%) were female, and 90.4% of the students started playing video games in primary school. When the 2 groups were compared according to the completion time of each exercise, Group I finished more quickly than Group II in the Peg Board-1 exercise (p>0.05), whereas Group II had better results in 3 exercises including Pick and Place, Ring and Rail, and Thread the Rings-1. However, none of the differences were found to be statistically significant (p>.05), and according to the overall scores based on the time to complete exercises, economy of motion, instrument collision, use of excessive instrument force, instruments out of view, and master workspace range, the scores were not statistically different between Groups I and II (p>.05). According to the basic robotic simulation exercise results, there was no difference between medical students who used to play video games and those who still played video games. Studies evaluating baseline visuospatial skills with larger sample sizes are needed.

  13. Ludic role of religious rituals. The use of play for religious ceremony

    2015-11-01

    Full Text Available This paper was made as part of a wider research I made about rituals and their meaning and roles they are playing in the religious system of thinking. The way they are thought, displayed, precisely followed as instructed and believed, makes them a powerful social act that has been always provided by any religion, and also a tool for religion to make the human society what it is today. After I speak about what is a ritual and its religious content in general, I am enumerating roles and functions of play and theatre in particular have, both for profane and religious purpose. Do we still use play/games as adults because they are rewarding, they give us pleasure? They are used as means of relaxation, or for continuing the age of childhood; or it is in our nature to play games in everything we do? In this paper I have emphasized play as adaptive potentiation or adaptive variability useful both in therapy, as in religious ceremony. The relation and comparison of rituals with play is due to the fact that playing is the most engaging behavior performed by man and animals, and it can be found as foundation of almost any ritualist activity.

    Directory of Open Access Journals (Sweden)

    Marinova T.Y.

    2015-09-01

    Full Text Available The paper addresses the issue of how massively multiplayer online role¬playing games (MMORPG affect the behavior of players. Basing on a series of research, the paper analyzes how massively multiplayer online role¬playing games are created and highlights their specifics that possibly contribute to the development of psychological addiction to such games. The authors describe the outcomes of their own research on motivation in persons with gaming addiction aged 18 and up, with over 1 year of gaming experience. These out-comes suggest that current traditional criteria developed for assessing gaming addiction cannot be applied to this particular form of addictive behavior.

    2017-08-01

    Medical students form an important part of the medical team; however, patients may not be fully aware of their role. Identifying students in the clinical setting is difficult because of their similar attire to other health care professionals. This parity may introduce unethical scenarios where patients may be speaking and consenting to individuals whom they do not recognise as students. A single-sided questionnaire was given to hospital in-patients during a 12-week period. Questions focused on the role of students. With their opinions, patients were given a list of clinical skills and asked whether or not they would allow a student to carry out these skills on themselves. The list included both required and non-required clinical skills by the General Medical Council (GMC). In total, 101 patients participated in the study: 34 males and 67 females. Age at admittance was 63.4 ± 18.0 years; 74.3 per cent of patients were able to identify a student, although 87.1 per cent believed that students should have a designated uniform. Patients were significantly more likely to allow a student to perform required skills on them, as opposed to non-required skills (p student made no difference in the likelihood of consenting to a skill being performed. Identifying students in the clinical setting is difficult CONCLUSIONS: The apparent trade-off between patient safety and providing students with learning opportunities has been of long standing concern. Patients consider GMC-required skills as largely appropriate; however, patients feel that students should be more identifiable, and increasing the awareness of the role and capabilities of a student in patient care is important. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    2017-09-01

    Full Text Available This article aims to analyze the play of make-believe for children with autism, focusing on the symbolic resources it uses in asserting roles. It is based on the theoretical contributions of the historical-cultural perspective, with Vygotsky as its main exponent. The research was carried out in a public school of Early Childhood Education, in Brasília. From the microgenetic analysis, the research had six children diagnosed with autism, at the ages of 4 and 6 years, included in Special Class, as participants. The play situations were videotaped and later transcribed in episode format. In the data analysis, we identified two axes, namely: 1 The construction of the role play and; 2 Assumption of roles by the child with autism: set design and imagery resources. The results reveal the role of the other (intentional participation in the constitution of play activity, especially the role of the adult. In addition, they demonstrate that pedagogical mediation, including the creation of 'scenarios', is fundamental for the extension of the symbolic experience of the child with autism.

    Full Text Available The present study examined the effects of role-play experience on children’s mindreading ability. Forty-one primary school children (20 boys, 21 girls, mean age: 9.37 years, range: 8–11 years were introduced to a communication task in which the use of mindreading was essential. During each trial, participants viewed a shelf, presented on a laptop, which contained several familiar objects, and they were instructed to touch an object on the shelf following an order issued by a manager who stood at the opposite side of the shelf. There were two managers: one was a monkey manager with normal color vision, and the other was a dog manager with restricted color vision. The monkey manager could see all the objects in the same colors as the participants, whereas the dog manager saw some objects in different colors. Participants were required to respond according to the manager's instruction. In the restricted color vision condition, the dog manager saw the colors of objects differently; thus, participants had to work out his intentions, according to his different perspective. In the normal color vision condition, all objects were in the same colors as those seen by the monkey manager. Before the test phase, participants in the role-play group were provided a role-play experience in which they assumed the role of the dog manager with restricted color vision. The experimental data were analyzed using a 2 x 2 mixed-design ANOVA (role-play condition x communication partner condition to examine differences in the error rate. Both main effects and its interaction were significant. According to the post-hoc analyses, participants in the no-role-play condition made significantly more errors in the restricted color vision condition than in the normal color vision condition, whereas no such difference was found among participants in the role-play condition. These results suggest that role-play experience could facilitate mindreading of characters with

    Whereas role-playing and table-top role-play games (RPGs) have been proven to have potential as therapeutic tools, playing RPGs is often stereotypically associated with social incompetence and psychiatric disorders. Knowledge regarding the stereotype and its implications is very scarce specifically among mental health practitioners. Therefore the present study aimed to narrow this gap in knowledge by examining the perception of Social Workers that are considered to be the forefront of mental health-care, in regard to the association between playing RPGs and mental health. A convenience sample of 130 Social Workers, recruited through social networks (e.g. Facebook, WhatsApp etc.), responded to an on-line survey dealing with their perception of their own knowledge on RPGs, the importance of such knowledge and the association between playing RPGs and mental illness. Results indicated an association between having higher knowledge of RPGs and lower perception of a link between playing RPGs and psychopathology. The study's findings emphasize the false stigma and its potential harmful implication on professionals' practice, especially in the context of intake process and primary diagnostic. The effect of familiarity is also discussed in light of the study's findings. • The perception of mental health professionals toward role playing games such as Dungeons and Dragons is understudied. • Social Workers' perception was measured in regard to the connection between use of RPGs and DSM-IV-TR psychopathology. • Greater knowledge of RPGs was found to be associated with lower perception of the connection between use of RPGs and DSM-IV-TR psychopathology.

    Knowledge about users interacting with Massively Multiplayer Online Role-Playing Games (MMORPG) is fundamental in order to prevent their potential negative effects on behavior. For this reason, the present study analyzed the relationship between styles of play and motivations. An online questionnaire asking for socio-demographic details, playing style, characteristics of the game played and motivations for playing, was answered by 430 Spanish-speaking MMORPG players (45.1% males). The identified profile for players, far away from the stereotype of an adolescent, consisted in a person who mainly plays on PvP (Player versus Player) servers, choosing the type of game according to his experience. Regarding motivations, they were interested in relating with other players through the game (Socialization), in discovering the game's possibilities and development of its adventures (Exploration), to a lesser extent in leadership and prestige (Achievement) and, lastly, identification with an avatar and escape from reality (Dissociation). Although part of the reason for playing was escapism and/or stress relief, the main motivation had a social nature. We conclude that MMORPG offer an attractive environment for a broad spectrum of people, and we have not been able to confirm the stereotype of a loner avoiding reality, taking refuge in games.

  7. Facebook levels the playing field: Dyslexic students learning through digital literacies

    Directory of Open Access Journals (Sweden)

    Owen Barden

    2014-02-01

    Full Text Available Dyslexia has an ambivalent relationship with learning technology. Any potential gains may be nullified if the technology is perceived to exacerbate stigma. This paper examines the use of an ‘everyday’ technology, Facebook, by a small group of sixth form students labelled as dyslexic. ‘Levelling the playing field’ is a phrase the participants used often when discussing what they wanted from learning technology. Because dyslexia usually is defined in terms of significant difficulties with literacy, we might reasonably anticipate that the participants would see Facebook as stigmatising rather than levelling the playing field, because of the very public literacy events that it demands. However, the data indicate that far from shying away from Facebook because of fear of their difficulties with literacy being exposed, the participants enthusiastically embraced it. The students saw Facebook as a desirable presence in their education, one that supported inclusion. For them, levelling the playing field with Facebook had five dimensions: keeping up to date and meeting deadlines; increased control over learning; developing metacognitive awareness; greater control over literacy process and demands; and being experts and helpers. The findings perhaps challenge some assumptions about dyslexia, literacy and learning, and may be of interest to teachers working with dyslexic students, or researchers studying learning in digitally mediated social networks.

    Dias, Roger Daglius; Scalabrini-Neto, Augusto

    2017-06-19

    To investigate acute stress response in residents playing nurse and physician roles during emergency simulations. Sixteen second-year internal medicine residents participated in teams of four (two playing physician roles and two playing nurse roles). Stress markers were assessed in 24 simulations at baseline (T1) and immediately after the scenario (T2), using heart rate, systolic and diastolic blood pressure, salivary α-amylase, salivary cortisol and salivary interleukin-1β. The State-Trait Anxiety Inventory was applied at T2. Continuous data were summarized for the median (1st-3rd interquartile ranges), and the Mann-Whitney U Test was used to compare the groups. The percent variations of the stress markers in the physician and nurse roles, respectively, were the following: heart rate: 70.5% (46.0-136.5) versus 53.0% (29.5-117.0), U=89.00, p=0.35; systolic blood pressure: 3.0% (0.0-10.0) versus 2.0% (-2.0-9.0), U=59.50, p=0.46; diastolic blood pressure: 5.5% (0.0-13.5) versus 0.0% (0.0-11.5), U=91.50, p=0.27; α-amylase: -5.35% (-62.70-73.90) versus 42.3% (12.4-133.8), U=23.00, p=0.08; cortisol: 35.3% (22.2-83.5) versus 42.3% (12.4-133.8), U=64.00, p=0.08); and interleukin-1β: 54.4% (21.9-109.3) versus 112.55% (29.7-263.3), U= 24.00, p=0.277. For the physician and nurse roles, respectively, the average heart rate was 101.5 (92.0-104.0) versus 91.0 (83.0-99.5) beats per minute, U=96.50, p=0.160; and the state anxiety inventory score was 44.0 (40.0-50.0) versus 42.0 (37.50-48.0) points, U= 89.50, p=0.319. Different roles during emergency simulations evoked similar participants' engagement, as indicated by acute stress levels. Role-play strategies can provide high psychological fidelity for simulation-based training, and these results reinforce the potential of role-play methodologies in medical education.

  12. Honouring Roles: The Story of a Principal and a Student

    Directory of Open Access Journals (Sweden)

    Jerome Cranston

    2012-11-01

    Full Text Available The importance of the teacher-student relationship in educational practice is well established, as is the idea of principal leadership in relationship to staff. Even though principal leadership is regarded as a factor in student success, the principal’s effect is usually assumed to take place via the teaching staff. There is an absence of research about the “lived experience” of direct principal-student relationships that shed lights on the ways in which these relationships playrole in student success and principal transformation. This paper presents two narratives written about a particular set of principal-student interactions experienced by the researcher (principal and participant (student.  The analysis uses a narrative inquiry approach to explore both the individual and collective meanings of this principal-student relationship. The stories and their derived meanings have the potential to enliven and  influence educational practice as they explore the subtleties of the principal-student relationship.

    2014-10-01

    To examine whether receipt of alcohol industry sponsorship is associated with problematic drinking in UK university students who play sport. University students (n = 2450) participating in sports were invited to complete a pen-and-paper questionnaire by research staff approaching them at sporting facilities and in university settings. Respondents were asked whether they, personally, their team and/or their club were currently in receipt of sponsorship (e.g. money, free or subsidized travel or sporting products) from an alcohol-related industry (e.g. bars, liquor stores, wholesalers), and whether they had solicited the sponsorship. Drinking was assessed using the Alcohol Use Disorders Identification Test (AUDIT). Questionnaires were completed by 2048 of those approached (response rate = 83%). Alcohol industry sponsorship was reported by 36% of the sample. After accounting for confounders (age, gender, disposable income and location) in multivariable models, receipt of alcohol sponsorship by a team (adjusted βadj  = 0.41, P = 0.013), club (βadj  = 0.73, P = 0.017), team and club (βadj  = 0.79, P = 0.002) and combinations of individual and team or club sponsorships (βadj  = 1.27, P 8). Respondents who sought out sponsorship were not at greater risk than respondents, or whose teams or clubs, had been approached by the alcohol industry. University students in the United Kingdom who play sport and who personally receive alcohol industry sponsorship or whose club or team receives alcohol industry sponsorship appear to have more problematic drinking behaviour than UK university students who play sport and receive no alcohol industry sponsorship. Policy to reduce or cease such sponsorship should be considered. © 2014 Society for the Study of Addiction.

    Cells respond to stress with repair, or are diverted into irreversible cell cycle exit (senescence) or are eliminated through programmed cell death. There are two major morphologically distinctive forms of programmed cell death, apoptosis and autophagic cell death. Apoptosis contribute to cell death, whereas autophagy can play a dual role in mediating either cell survival or death in response to various stress stimuli. Here we analysed cellular responses induced by IR. The understanding of an appropriate cellular stress response is of crucial importance in foreseeing the cell fate. Apoptotic feagures were not detected in HeLa under our experimental irradiation condition. Autophagic cell death in HeLa may play an important role in cell protection and can result in cell survival

  17. ROLE-PLAYS VS. NATURAL DATA: ASKING FOR A DRINK AT A CAFETERIA IN PENINSULAR SPANISH

    Rebeca Bataller

    2013-08-01

    Full Text Available The purpose of this study is to compare the data collected, via two methods, from two groups of Peninsular Spanish native speakers in a service encounter scenario. The methods chosen are open role-plays and naturally occurring interactions, two frequently used approaches in the field of pragmatics. The naturalistic data from this study consisted of request-for-service transactions at cafeterias in Valencia, Spain; these were recorded with audio equipment and then analyzed at the illocutionary and discourse levels. The features analyzed were the strategies and mitigating devices used in all phases of the interactions. The structure and length of interactions from each dataset were also compared. The results of this comparative study indicate that the role-play data resembled the naturalistic interactions in some respects, but there were also some significant differences between the two datasets that may be attributed to the particular type of collection method.

  18. On whether mirror neurons play a significant role in processing affective prosody.

    Science.gov (United States)

    Ramachandra, Vijayachandra

    2009-02-01

    Several behavioral and neuroimaging studies have indicated that both right and left cortical structures and a few subcortical ones are involved in processing affective prosody. Recent investigations have shown that the mirror neuron system plays a crucial role in several higher-level functions such as empathy, theory of mind, language, etc., but no studies so far link the mirror neuron system with affective prosody. In this paper is a speculation that the mirror neuron system, which serves as a common neural substrate for different higher-level functions, may play a significant role in processing affective prosody via its connections with the limbic lobe. Actual research must apply electrophysiological and neuroimaging techniques to assess whether the mirror neuron systems underly affective prosody in humans.

    INTRODUCTION: Despite initiatives to integrate treatment and care across organisations, patient trajectories in Danish health-care are not well coordinated. Coordination among many health-care professionals is essential, and it is frequently suggested that a single person should perform the task....... In the majority of cases, GPs had no access to information or were not informed about hospital decisions affecting the patients' trajectories, and they were therefore unable to perform a coordinating role. CONCLUSION: GPs only played a minor or no role at all as coordinators of individual cancer patient...

    2016-06-01

    Background Problematic Internet use (PIU) is an emerging entity with varied contents. Behavioral addictions have high comorbidity of attention deficit hyperactivity disorder and obsessive-compulsive spectrum disorders. Social networking site (SNS) addiction and role playing game (RPG) addiction are traditionally studied as separate entities. We present a case with excessive Internet use, with a particular focus on phenomenology and psychiatric comorbidities. Case presentation Fifteen-year-old girl with childhood onset attention deficit disorder, obsessive-compulsive disorder, adolescent onset trichotillomania, and disturbed family environment presented with excessive Facebook use. Main online activity was creating profiles in names of mainstream fictional characters and assuming their identity (background, linguistic attributes, etc.). This was a group activity with significant socialization in the virtual world. Craving, salience, withdrawal, mood modification, and conflict were clearly elucidated and significant social and occupational dysfunction was evident. Discussion This case highlights various vulnerability and sociofamilial factors contributing to behavioral addiction. It also highlights the presence of untreated comorbidities in such cases. The difference from contemporary RPGs and uniqueness of role playing on SNS is discussed. SNS role playing as a separate genre of PIU and its potential to reach epidemic proportions are discussed. Conclusions Individuals with temperamental vulnerability are likely to develop behavioral addictions. Identification and management of comorbid conditions are important. The content of PIU continues to evolve and needs further study.

    Heru, Alison M

    2011-01-01

    Problem-based learning (PBL) has been implemented in medical education world-wide. Despite its popularity, it has not been generally considered useful for residency programs. The author presents a model for the implementation of PBL in residency programs. The author presents a description of a PBL curriculum for teaching psychosomatic medicine to PGY 2 members in a psychiatry training program. The goals of PBL are to encourage self-directed learning; enhance curiosity, using case-based, contextualized learning; promote collaborative practice; and support patient-centered care. The addition of role-playing exercises helps PGY 2 residents to develop their skills from simply developing a differential diagnosis to being able to construct biopsychosocial formulations, and it provides these residents an opportunity to practice presenting case formulations to the patient and family. Residents and faculty enjoyed the PBL role-playing sessions. Residents wanted the learning objectives given to them rather than generating their own learning objectives, to move through the cases faster, and to receive more information and more cases. Teaching psychosomatic medicine, using PBL and role-playing, allows many of the proposed Academy of Psychosomatic Medicine residency core competencies to be met. However, further refinement of the PBL method needs to take place in order to adapt its use to residency programs.

    Expression of inositol-1,4,5-trisphosphate (IP3) receptor-binding protein (IRBIT) has been reported in epithelial cells. However, its role in pHi regulation is not well understood. In this study, we investigated the role of IRBIT in pHi regulation, mediated by Na(+)/H(+) exchangers (NHEs), in salivary glands. We measured pHi recovery from cell acidification in BCECF-loaded salivary HSG cells. Western blot and co-immunoprecipitation (CO-IP) assays were also performed, showing that NHE1, 2 and 3 are expressed, and IRBIT binds to NHE3. HOE642, a specific NHE1 blocker, inhibited pHi recovery, but 40% pH(i) recovery was still observed even at the highest concentration of HOE642. Furthermore, pretreatment of the cells with siIRBIT significantly inhibited pHi recovery, indicating that NHE3 potentially plays a role in pHi recovery as well. The amount of membrane-localized NHE3 and its interaction with IRBIT are also significantly increased by cell acidification. In addition, we found that Ste20p-related proline alanine-rich kinase (SPAK) reverses the effect of IRBIT on membrane NHE3 translocation. Taken together, we conclude that IRBIT plays an important role in pHi regulation, mediated by NHE3, and further regulated by SPAK. Copyright © 2013 Elsevier Inc. All rights reserved.

    Effectively handling telephone calls about nursing home (NH) residents is an important skill for healthcare professionals, but little formal training is typically provided. The objective of the current study was to describe and evaluate the effectiveness of a novel structured role-playing didactic session followed by an on-call NH longitudinal clinical experience. The effectiveness of the structured role-playing didactic session was compared in different learners, including geriatric medicine fellows (n = 10), family medicine residents and faculty (n = 14), nurse practitioner students (n = 31), and other learners (n = 7). The curriculum focused on common problems encountered while caring for NH residents during on-call periods. Learners rated themselves using an 18-item pre/post questionnaire including five attitude and 13 skills questions, using a 1-to-5 Likert scale. T-tests were used to compare means before and after sessions. Significant improvements were found in overall mean attitudes and skills scores. For all learners, the greatest improvements were seen in "comfort in managing residents at the NH," "managing feeding or gastrostomy tube dislodgement," "identifying different availability of medications, laboratory studies, and procedures in NH," and "describing steps to send NH residents to the emergency department." Geriatric medicine fellows' attitudes and skills improved significantly after the longitudinal clinical experience. The faculty survey demonstrated improved documentation, communication, and fellows' management of on-call problems after curriculum implementation. This novel curriculum used role-playing to provide training for on-call management of NH residents. This curriculum has been successfully disseminated on a national geriatrics educational resource website (POGOe) and is applicable to geriatric medicine fellowships, internal medicine and family medicine residency programs, and other training programs. © 2013, Copyright the Authors

    Okamoto, Shusuke; Kamada, Masaru; Yonekura, Tatsuhiro

    This letter proposes a prototyping tool for Web-based Multiuser Online Role-Playing Game (MORPG). The design goal is to make this tool simple and powerful. The tool is comprised of a GUI editor, a translator and a runtime environment. The GUI editor is used to edit state-transition diagrams, each of which defines the behavior of the fictional characters. The state-transition diagrams are translated into C program codes, which plays the role of a game engine in RPG system. The runtime environment includes PHP, JavaScript with Ajax and HTML. So the prototype system can be played on the usual Web browser, such as Fire-fox, Safari and IE. On a click or key press by a player, the Web browser sends it to the Web server to reflect its consequence on the screens which other players are looking at. Prospected users of this tool include programming novices and schoolchildren. The knowledge or skill of any specific programming languages is not required to create state-transition diagrams. Its structure is not only suitable for the definition of a character behavior but also intuitive to help novices understand. Therefore, the users can easily create Web-based MORPG system with the tool.

  14. Exploring Partnerships between Local Communities and Timber Companies: An Experiment Using the Role-Playing Games Approach

    Full Text Available Cooperation among stakeholders is widely accepted as an effective management strategy. This paper describes an experimental study that explores this cooperation using role-playing games, which is formulated within a multiagent simulation framework. This framework enables participants to take active roles in mimicking the collaborative decision environment and the behaviors and attitudes of the different stakeholders. The paper examines a forest plantation company in South Sumatra, Indonesia, which has cooperated with local communities since 2000. The experimental pilot study described in this paper explored the role of communication in partnership relationships between the company and the local communities living within and around the surroundings of the company's plantation. These partnerships were explored and analyzed using the gaming approach involving university students taking the role of forest stakeholders, from both the timber company and the local communities. Lessons learned from the game provided the rationale for the establishment of a communication institution called “Forum Sebahu Sejalan.” This formal forum was constituted after a facilitated ex-postinteraction between representatives from the timber company and local communities. Results and observations drawn from the interactions show the potentials of the RPG approach and the formal forum in crafting resilient partnerships among stakeholders.

    2016-05-01

    Routine school attendance is necessary for youth to develop into well-educated, successful adult citizens who will make significant contributions to society. Yet over 5 million students in the United States are chronically absent missing more than 10% of school in a year. The growing problem of chronic absenteeism among youth can be linked to increases in chronic health conditions in childhood such as allergies, asthma, diabetes, and obesity. School nurses are in an ideal position to play a vital role in reducing chronic student absenteeism, enabling youth to achieve their maximum learning potential. However, the role of the school nurse has not historically been recognized as a key factor for assisting youth to be present and regularly engaged in school. This feature article highlights a hospital-funded school nurse program within the state of Michigan that has reduced chronic absenteeism rates by placing school nurses into schools where previously there were none. The program implemented a number of initiatives that were instrumental in increasing the health and safety of students and provides a unique "before and after" glimpse of how school nursing reduces chronic student absenteeism rates and validates the essential role of the nurse within the educational system. © 2016 The Author(s).

    2017-06-01

    The Nanosilver Linings role play case offers participants first-person experience with interpersonal interaction in the context of the wicked problems of emerging technology macroethics. In the fictional scenario, diverse societal stakeholders convene at a town hall meeting to consider whether a nanotechnology-enabled food packaging industry should be offered incentives to establish an operation in their economically struggling Midwestern city. This original creative work was built with a combination of elements, selected for their established pedagogical efficacy (e.g. active learning, case-based learning) and as topical dimensions of the realistic scenario (e.g. nanosilver in food packaging, occupational safety and health). The product life cycle is used as a framework for integrated consideration of scientific, societal, and ethical issues. The Nanosilver Linings hypothetical case was delivered through the format of the 3-hour workshop Ethics when Biocomplexity meets Human Complexity, providing an immersive, holistic ethics learning experience for STEM graduate students. Through their participation in the Nanosilver Linings case and Ethics when Biocomplexity meets Human Complexity workshop, four cohorts of science and engineering doctoral students reported the achievement of specific learning objectives pertaining to a range of macroethics concepts and professional practices, including stakeholder perspectives, communication, human values, and ethical frameworks. Automated text analysis of workshop transcripts revealed differences in sentiment and in ethical framework (consequentialism/deontology) preference between societal stakeholder roles. These resources have been recognized as ethics education exemplars by the U.S. National Academy of Engineering .

    Full Text Available This study explored the impact of role-playing on the quality of peer feedback and learners’ perception of this strategy in a case-based learning activity with VoiceThread in an online course. The findings revealed potential positive impact of role-playing on learners’ generation of constructive feedback as role-playing was associated with higher frequency of problem identification in the peer comments. Sixty percent of learners perceived the role-play strategy useful in assisting them to compose and provide meaningful feedback. Multiple motivations drove learners in making decisions on role choice when responding to their peers, mostly for peer benefits. Finally, 90% of learners reported the peer feedback useful or somewhat useful. Based on the findings of this study, we discussed educational and instructional design implications and future directions to further the line of research using role-play strategy to enhance peer feedback activity.

  1. Transforming Water Supply Regimes in India: Do Public-Private Partnerships Have a Role to Play?

    2010-10-01

    Full Text Available Public-private partnerships (PPP are an important governance strategy that has recently emerged as a solution to enhance the access of marginalised residents to urban infrastructures. With the inception of neo-liberal economic reforms in India, in Indian cities too PPP has emerged as an innovative approach to expand coverage of water supply and sanitation infrastructures. However, there has been little study of the dynamics of partnership efforts in different urban contexts: What role do they play in transforming existing infrastructure regimes? Do reform strategies such as partnerships result in increased privatisation or do they make the governance of infrastructures more participative? Reviewing some of the recent literature on urban political analysis, this article develops the concept of water supply regime to describe the context of water provision in three metropolitan cities in India. To further our understanding of the role of PPP within regimes, this article sketches five cases of water supply and sanitation partnerships located within these three metropolitan cities. From these empirical studies, the article arrives at the conclusion that while PPP are always products of the regime-context they are inserted within, quite often strategic actors in the partnership use the PPP to further their interests by initiating a shift in the regime pathway. This leads us to conclude that PPPs do play a role in making water supply regimes more participative but that depends on the nature of the regime as well as the actions of partners.

  2. The PICALM protein plays a key role in iron homeostasis and cell proliferation.

    Directory of Open Access Journals (Sweden)

    Paula B Scotland

    Full Text Available The ubiquitously expressed phosphatidylinositol binding clathrin assembly (PICALM protein associates with the plasma membrane, binds clathrin, and plays a role in clathrin-mediated endocytosis. Alterations of the human PICALM gene are present in aggressive hematopoietic malignancies, and genome-wide association studies have recently linked the PICALM locus to late-onset Alzheimer's disease. Inactivating and hypomorphic Picalm mutations in mice cause different degrees of severity of anemia, abnormal iron metabolism, growth retardation and shortened lifespan. To understand PICALM's function, we studied the consequences of PICALM overexpression and characterized PICALM-deficient cells derived from mutant fit1 mice. Our results identify a role for PICALM in transferrin receptor (TfR internalization and demonstrate that the C-terminal PICALM residues are critical for its association with clathrin and for the inhibitory effect of PICALM overexpression on TfR internalization. Murine embryonic fibroblasts (MEFs that are deficient in PICALM display several characteristics of iron deficiency (increased surface TfR expression, decreased intracellular iron levels, and reduced cellular proliferation, all of which are rescued by retroviral PICALM expression. The proliferation defect of cells that lack PICALM results, at least in part, from insufficient iron uptake, since it can be corrected by iron supplementation. Moreover, PICALM-deficient cells are particularly sensitive to iron chelation. Taken together, these data reveal that PICALM plays a critical role in iron homeostasis, and offer new perspectives into the pathogenesis of PICALM-associated diseases.

    Soy-based infant formula contains high levels of isoflavones. These estrogen-like compounds have been shown to induce changes in sexually dimorphic behaviors in animals exposed in early development. We examined gender-role play behavior in relation to soy-based and non-soy-based infant feeding methods among children in the Avon Longitudinal Study of Parents and Children. We studied 3,664 boys and 3,412 girls. Four exposure categories were created using data from questionnaires administered at 6 and 15 months postpartum: primarily breast, early formula (referent), early soy, and late soy. Gender-role play behavior was assessed using the Pre-School Activities Inventory (PSAI). Associations between infant feeding and PSAI scores at 42 months of age were assessed using linear regression. Post hoc analyses of PSAI scores at 30 and 57 months were also conducted. Early-infancy soy use was reported for approximately 2% of participants. Mean [95% confidence interval (CI)] PSAI scores at 42 months were 62.3 (62.0, 62.6) and 36.9 (36.6, 37.2) for boys and girls, respectively. After adjustment, early soy (vs. early formula) feeding was associated with higher (less feminine) PSAI scores in girls (β = 2.66; 95% CI: 0.19, 5.12) but was not significantly associated with PSAI scores in boys. The association between soy exposure and PSAI scores in girls was substantially attenuated at 30 and 57 months. Although not consistent throughout childhood, early-life soy exposure was associated with less female-typical play behavior in girls at 42 months of age. Soy exposure was not significantly associated with play behavior in boys.

  4. What role did the Hikurangi subduction zone play in the M7.8 Kaikoura earthquake?

    The 2016 M7.8 Kaikoura earthquake ruptured at least a dozen faults in the northern South Island of New Zealand, within the transition from the Hikurangi subduction zone (in the North Island) to the transpressive Alpine Fault (in the central South Island). The role that the southern end of the Hikurangi subduction zone played (or did not play) in the Kaikoura earthquake remains one of the most controversial aspects of this spectacularly complex earthquake. Investigations using near-field seismological and geodetic data suggest a dominantly crustal faulting source for the event, while studies relying on teleseismic data propose that a large portion of the moment release is due to rupture of the Hikurangi subduction interface beneath the northern South Island. InSAR and GPS data also show that a large amount of afterslip (up to 0.5 m) occurred on the subduction interface beneath the crustal faults that ruptured in the M7.8 earthquake, during the months following the earthquake. Modeling of GPS velocities for the 20 year period prior to the earthquake indicate that interseismic coupling was occurring on the Hikurangi subduction interface beneath the northern South Island, in a similar location to the suggested coseismic and postseismic slip on the subduction interface. We will integrate geodetic, seismological, tsunami, and geological observations in an attempt to balance the seemingly conflicting views from local and teleseismic data regarding the role that the southern Hikurangi subduction zone played in the earthquake. We will also discuss the broader implications of the observed coseismic and postseismic deformation for understanding the kinematics of the southern termination of the Hikurangi subduction zone, and its role in the transition from subduction to strike-slip in the central New Zealand region.

  5. DICER-LIKE2 plays a primary role in transitive silencing of transgenes in Arabidopsis.

    2008-03-01

    Full Text Available Dicer-like (DCL enzymes play a pivotal role in RNA silencing in plants, processing the long double-stranded RNA (dsRNA that triggers silencing into the primary short interfering RNAs (siRNAs that mediate it. The siRNA population can be augmented and silencing amplified via transitivity, an RNA-dependent RNA polymerase (RDR-dependent pathway that uses the target RNA as substrate to generate secondary siRNAs. Here we report that Arabidopsis DCL2-but not DCL4-is required for transitivity in cell-autonomous, post-transcriptional silencing of transgenes. An insertion mutation in DCL2 blocked sense transgene-induced silencing and eliminated accumulation of the associated RDR-dependent siRNAs. In hairpin transgene-induced silencing, the dcl2 mutation likewise eliminated accumulation of secondary siRNAs and blocked transitive silencing, but did not block silencing mediated by primary siRNAs. Strikingly, in all cases, the dcl2 mutation eliminated accumulation of all secondary siRNAs, including those generated by other DCL enzymes. In contrast, mutations in DCL4 promoted a dramatic shift to transitive silencing in the case of the hairpin transgene and enhanced silencing induced by the sense transgene. Suppression of hairpin and sense transgene silencing by the P1/HC-Pro and P38 viral suppressors was associated with elimination of secondary siRNA accumulation, but the suppressors did not block processing of the stem of the hairpin transcript into primary siRNAs. Thus, these viral suppressors resemble the dcl2 mutation in their effects on siRNA biogenesis. We conclude that DCL2 plays an essential, as opposed to redundant, role in transitive silencing of transgenes and may play a more important role in silencing of viruses than currently thought.

  6. Trusted Sources: The Role Scientific Societies Can Play in Improving Public Opinions on Climate Change

    McEntee, C.; Cairns, A.; Buhrman, J.

    2012-12-01

    Public acceptance of the scientific consensus regarding climate change has eroded and misinformation designed to confuse the public is rapidly proliferating. Those issues, combined with an increase of politically motivated attacks on climate scientists and their research, have led to a place where ideology can trump scientific consensus as the foundation for developing policy solutions. The scientific community has been, thus far, unprepared to respond effectively to these developments. However, as a scientific society whose members engage in climate science research, and one whose organizational mission and vision are centered on the concepts of science for the benefit of humanity and ensuring a sustainable future, the American Geophysical Union can, and should, play an important role in reversing this trend. To that end, in 2011, AGU convened a Leadership Summit on Climate Science Communication, in which presidents, executive directors, and senior public policy staff from 17 scientific organizations engaged with experts in the social sciences regarding effective communication of climate science and with practitioners from agriculture, energy, and the military. The discussions focused on three key issues: the environment of climate science communication; public understanding of climate change; and the perspectives of consumers of climate science-based information who work with specific audiences. Participants diagnosed previous challenges and failings, enumerated the key constituencies that need to be effectively engaged, and identified the critical role played by cultural cognition—the influence of group values, particularly around equality and authority, individualism, and community; and the perceptions of risk. Since that meeting, AGU has consistently worked to identify and explore ways that it, and its members, and improve the effectiveness of their communication with the public about climate change. This presentation will focus on the insights AGU has

    2008-01-01

    The term stimulus, as it was used in science from its earliest appearance in the sixteenth century up to the beginning of the nineteenth century, shows a gradual progress in denotation from the physical object designed to produce nervous and muscular excitation to the generically conceived event or object that initiates sensory or motor activity. To this shift corresponds a shift in the understanding of sensory experience. Johannes Muller's law of specific energy of sensory nerves played a major role in the shift, and Hermann von Helmholtz gave the shift its most thorough philosophical explanation.

    Frequently, when an environmental issue requiring quantitative analysis surfaces, the development of a model synthesizing all aspects of the problem and applicable at each stage of the decision process is proposed. A more desirable alternative is to generate models specifically designed to meet the requirements of each level in decision making and which can be adapted in response to the changing status of the environmental issue. Various models of the global carbon cycle constructed to predict levels of CO 2 in the atmosphere as a result of man's activities are described to illustrate this point. In summary, the progression of models developed to analyze the global carbon cycle in resolving the CO 2 /climate issue indicates the changing character of models depending on the immediate role they play in environmental decision making. The dominant and successful role served by models in the carbon cycle problem points to the desirability of this flexible approach

    Full Text Available Behçet's Disease is a complex inflammatory disease, of unknown aetiology. While disease pathogenesis remains unclear, a strong relationship between Behçet’s Disease and HLA-B*51 has been established over the last 30 years. A number of theories exist regarding the cause of Behçet's Disease, however few are able to account for the increased rates of HLA-B*51 positive individuals, particularly around the Mediterranean basin and Middle East where the prevalence is highest. This review outlines current immunogenetic data on Behçet’s disease and the immunoregulatory role natural killer cells may play. It also describes the interaction of the killer immunoglobulin-like receptor - KIR3DL1 with its ligand Bw4, which is found on HLA-B51. Finally, CD94/NKG2D, MICA and ERAP are outlined with regard to their potential roles in Behçet’s disease.

    The role played by the Coulombic traction for an interface crack in dissimilar piezoelectric materials is clarified. Based on the extended Stroh theory, the Coulombic traction, usually neglected in piezoelectric fracture, is imposed on the interface crack surfaces. It is found that the low-capacitance medium (air or vacuum) inside the crack gap yields some large Coulombic traction as compared to the applied mechanical loading whether the remanent polarization of piezoelectric material is considered or not. Thus, previous investigations based on the traction-free condition underestimate the role of the Coulombic traction and in turn may yield unexpected errors for the effective stress intensity factor (SIF) and energy release rate (ERR) at the crack tip.

    Full Text Available Gender education as an important part of education, affects by the role and attitudes of teachers. Including gender perspective in schools is a prerequisite in alienable of human development, instead insuring gender equality it is considered as respecting human rights. Elimination of the gender stereotypes has a two-fold significance since itemsurest gender equality not only in the school system but even in the society as a whole. Gender stereotype messages, regardless by hidden or displayed form, unilaterally influence the development of the personality in its appearance as well as the formation of the individual. Children learn about gender identity simply by observing what happens in different circumstances around. In education exist gender disparities, which can be assessed by means of measurable indicators. So, the content of the curricula and instructive texts, the interactive relationships teacher-students, the institutional ambiance, etc. play an important role into the preservation and transmission of the gender disparity stereotypes through the messages they convey. The purpose of thestudy is to perform a systematic research in order to show the scale and shape in which gender stereotypes are portrayed and shown in social life, even through the role model of teacher and their affecting the education for a democratic society. To achieve this goal, we use the method of studying the existing literature; a detailed analysis of the questionnaires and interviews content with school directors and teachers of pre-university education in city: Shkodër, Tiranë, Elbasan, Pogradec, Korçë. Parents and teachers attitudes, seems to be a role model and affect the education of students. Therefore it is necessary before to teach students about gender equality, teachers need to be careful in their behavior about gender equality as an integral part of thinking. Need to have successful teacher, to get successful students otherwise should be successful

  7. Histidine Metabolism and IGPD Play a Key Role in Cefquinome Inhibiting Biofilm Formation of Staphylococcus xylosus

    2018-04-01

    Full Text Available Staphylococcus xylosus (S. xylosus is an AT-rich and coagulase-negative Staphylococcus (CNS. It is normally regarded as non-pathogenic, however, recent studies have demonstrated that it is related to human opportunistic infections and bovine mastitis. In addition, S. xylosus strains have the ability to form biofilm. Biofilms are also involved in chronic infections and antibiotic resistance, there are only a few reports about cefquinome inhibiting S. xylosus biofilm formation and the protein targets of cefquinome. In our study, we found that sub-MICs of cefquinome were sufficient to inhibit biofilm formation. To investigate the potential protein targets of cefquinome, we used iTRAQ for the analyses of cells at two different conditions: 1/2-MIC (0.125 μg/mL cefquinome treatment and no treatment. Using iTRAQ technique and KEGG database analysis, we found that proteins differently expression in histidine metabolism pathway may play a role in the process by which 1/2-MIC (0.125 μg/mL cefquinome inhibits S. xylosus biofilm formation. Interestingly, we found a sharply down-regulated enzyme [A0A068E9J3 imidazoleglycerol-phosphate dehydratase (IGPD] involved in histidine metabolism pathway in cefquinome-treated cells. We demonstrated the important role of IGPD in sub-MICs cefquinome inhibiting biofilm formation of S. xylosus by gene (hisB knockout, IGPD enzyme activity and histidine content assays. Thus, our data sheds light on important role of histidine metabolism in S. xylosus biofilm formation; especially, IGPD involved in histidine metabolism might play a crucial role in sub-MICs cefquinome inhibition of biofilm formation of S. xylosus, and we propose IGPD as an attractive protein target of cefquinome.

  8. LKR/SDH plays important roles throughout the tick life cycle including a long starvation period.

    Banzragch Battur

    Full Text Available BACKGROUND: Lysine-ketoglutarate reductase/saccharopine dehydrogenase (LKR/SDH is a bifunctional enzyme catalyzing the first two steps of lysine catabolism in plants and mammals. However, to date, the properties of the lysine degradation pathway and biological functions of LKR/SDH have been very little described in arthropods such as ticks. METHODOLOGY/PRINCIPAL FINDINGS: We isolated and characterized the gene encoding lysine-ketoglutarate reductase (LKR, EC 1.5.1.8 and saccharopine dehydrogenase (SDH, EC 1.5.1.9 from a tick, Haemaphysalis longicornis, cDNA library that encodes a bifunctional polypeptide bearing domains similar to the plant and mammalian LKR/SDH enzymes. Expression of LKR/SDH was detected in all developmental stages, indicating an important role throughout the tick life cycle, including a long period of starvation after detachment from the host. The LKR/SDH mRNA transcripts were more abundant in unfed and starved ticks than in fed and engorged ticks, suggesting that tick LKR/SDH are important for the starved tick. Gene silencing of LKR/SDH by RNAi indicated that the tick LKR/SDH plays an integral role in the osmotic regulation of water balance and development of eggs in ovary of engorged females. CONCLUSIONS/SIGNIFICANCE: Transcription analysis and gene silencing of LKR/SDH indicated that tick LKR/SDH enzyme plays not only important roles in egg production, reproduction and development of the tick, but also in carbon, nitrogen and water balance, crucial physiological processes for the survival of ticks. This is the first report on the role of LKR/SDH in osmotic regulation in animals including vertebrate and arthropods.

    Context/PurposeWe experienced a new teaching and learning technology: a Computer Class Role Playing Game (RPG) to perform educational activity in classrooms through an interactive game. This approach is new, there are some experiences on educational games, but mainly individual and not class-based. Gaming all together in a class, with a single scope for the whole class, it enhances peer collaboration, cooperative problem solving and friendship. MethodsTo perform the research we experimented the games in several classes of different degrees, acquiring specific questionnaire by teachers and pupils. Results Experimental results were outstanding: RPG, our interactive activity, exceed by 50% the overall satisfaction compared to traditional lessons or Power Point supported teaching. InterpretationThe appreciation of RPG was in agreement with the class level outcome identified by the teacher after the experimentation. Our work experience get excellent feedbacks by teachers, in terms of efficacy of this new teaching methodology and of achieved results. Using new methodology more close to the student point of view improves the innovation and creative capacities of learners, and it support the new role of teacher as learners' "coach". ConclusionThis paper presents the first experimental results on the application of this new technology based on a Computer game which project on a wall in the class an adventure lived by the students. The plots of the actual adventures are designed for deeper learning of Science, Technology, Engineering, Mathematics (STEM) and Social Sciences & Humanities (SSH). The participation of the pupils it's based on the interaction with the game by the use of their own tablets or smartphones. The game is based on a mixed reality learning environment, giving the students the feel "to be IN the adventure".

  10. Does the magnetic expansion factor (fs) play a role in solar wind acceleration?

    For the past 25 years, magnetic expansion factor (fs) has been a key parameter used in the calculation of terminal solar wind speed (vsw) in both the Wang-Sheeley-Arge (WSA) model and its predecessor the Wang-Sheeley (WS) model. Since the discovery of an inverse relationship between fs and vsw, the physical role that magnetic expansion factor plays in the acceleration of the solar wind has been explored and debated. In this study, we investigate whether magnetic expansion factor plays a causal role in determining the terminal speed of the solar wind or merely serves as proxy. To do so, we explore how fs, as determined by WSA, relates to vsw for two different scenarios: 1) extended periods where the fast solar wind emerges from the centers of large coronal holes, and 2) periods where the solar wind emerges from pseudostreamers. For these same scenarios, we will also consider an alternative empirical relationship between solar wind speed and the minimum angular distance at the photosphere of a solar wind source to the nearest coronal hole boundary (i.e., DCHB, θb). We then compare these two different prediction techniques directly with heliospheric observations (i.e., ACE, STEREO-A & B, Ulysses) of solar wind speed to determine whether one clearly out performs the other.

    The gut microbiome, an aggregate genome of trillions of microorganisms residing in the human gastrointestinal tract, is now known to play a critical role in human health and predisposition to disease. It is also involved in the biotransformation of xenobiotics and several recent studies have shown that the gut microbiota can affect the pharmacokinetics of orally taken drugs with implications for their oral bioavailability. Review of Pubmed, Web of Science and Science Direct databases for the years 1957-2016. Recent studies make it clear that the human gut microbiota can play a major role in the metabolism of xenobiotics and, the stability and oral bioavailability of drugs. Over the past 50 years, more than 30 drugs have been identified as a substrate for intestinal bacteria. Questions concerning the impact of the gut microbiota on drug metabolism, remain unanswered or only partially answered, namely (i) what are the molecular mechanisms and which bacterial species are involved? (ii) What is the impact of host genotype and environmental factors on the composition and function of the gut microbiota, (iii) To what extent is the composition of the intestinal microbiome stable, transmissible, and resilient to perturbation? (iv) Has past exposure to a given drug any impact on future microbial response, and, if so, for how long? Answering such questions should be an integral part of pharmaceutical research and personalised health care.

    The purpose of this study was to implement and measure the effectiveness of a single-session assertiveness music therapy role playing protocol for psychiatric inpatients. Participants (N=133) were randomly assigned by group to one of three conditions: (a) Assertiveness Music Therapy, (b) No Music Assertiveness, or (c) Music No Assertiveness. Participants in both assertiveness conditions role played a number of different commonly occurring scenarios at an inpatient psychiatric facility and in the community. There were no significant between-group differences in posttest quality of life, locus of control, or other subscales. However, participants in both assertiveness conditions tended to have slightly higher internal locus of control and overall quality of life scores than participants in the music no assertiveness condition. Additionally, the assertiveness music therapy condition had higher attendance rates than the other conditions. A higher percentage of participants from both the assertiveness music therapy and music no assertiveness conditions indicated they thought their session was the most helpful/therapeutic group therapy session in which they had participated; this was not the case for the assertiveness no music condition. Future research is warranted to measure the effects of protocols that can help psychiatric patients generalize skills learned in treatment.

    Sexual risk reduction interventions are often ineffective for women who drink alcohol. The present study examines whether an alcohol-related sexual risk reduction intervention successfully trains women to increase assertive communication behaviors and decrease aggressive communication behaviors. Women demonstrated their communication skills during interactive role-plays with male role-play partners. Young, unmarried, and nonpregnant African American women (N = 228, ages 18-24) reporting unprotected vaginal or anal sex and greater than three alcoholic drinks in the past 90 days were randomly assigned to a control, a sexual risk reduction, or a sexual and alcohol risk reduction (NLITEN) condition. Women in the NLITEN condition significantly increased assertive communication behavior compared to women in the control condition, yet use of aggressive communicative behaviors was unchanged. These data suggest assertive communication training is an efficacious component of a sexual and alcohol risk reduction intervention. Public health practitioners and health educators may benefit from group motivational enhancement therapy (GMET) training and adding a GMET module to existing sexual health risk reduction interventions. Future research should examine GMET's efficacy in combination with other evidence-based interventions within other populations and examine talking over and interrupting one's sexual partner as an assertive communication behavior within sexual health contexts. © 2016 Society for Public Health Education.

    Family physicians (FPs) are increasingly involved in delivering genetic services. Familiarization with aspects of genetic counseling may enable FPs to help patients make informed choices. Exploration of interactive role-play as a means to raise FPs' awareness of the process and content of genetic counseling. FPs attending two large Canadian family medicine conferences in 2005 were eligible -- 93 participated. FPs discussed a case during a one-on-one session with a genetic counselor. Evaluation involved pre and post intervention questionnaires FPs' baseline genetic knowledge was self-rated as uniformly poor. Baseline confidence was highest in eliciting family history and providing psychosocial support and lowest in discussing risks/benefits of genetic testing and counseling process. Post-intervention, 80% of FPs had better appreciation of family history and 97% indicated this was an effective learning experience. Role-play with FPs is effective in raising awareness of the process and content of genetic counseling and may be applied to other health disciplines.

    Silent mating type information regulation 2 homologue 1 (SIRT1) activity and content increased significantly in overload-induced hypertrophy. SIRT1-mediated signalling through Akt, the endothelial nitric oxide synthase mediated pathway, regulates anabolic process in the hypertrophy of skeletal muscle. The regulation of catabolic signalling via forkhead box O 1 and protein ubiquitination is SIRT1 dependent. Overload-induced changes in microRNA levels regulate SIRT1 and insulin-like growth factor 1 signalling. Significant skeletal muscle mass guarantees functional wellbeing and is important for high level performance in many sports. Although the molecular mechanism for skeletal muscle hypertrophy has been well studied, it still is not completely understood. In the present study, we used a functional overload model to induce plantaris muscle hypertrophy by surgically removing the soleus and gastrocnemius muscles in rats. Two weeks of muscle ablation resulted in a 40% increase in muscle mass, which was associated with a significant increase in silent mating type information regulation 2 homologue 1 (SIRT1) content and activity (P overload-induced hypertrophy. These findings, along with the well-known regulatory roles that SIRT1 plays in modulating both anabolic and catabolic pathways, allow us to propose the hypothesis that SIRT1 may actually play a crucial causal role in overload-induced hypertrophy of skeletal muscle. This hypothesis will now require rigorous direct and functional testing. © 2017 The Authors. The Journal of Physiology © 2017 The Physiological Society.

  16. Involving consumers in product design through collaboration: the case of online role-playing games.

    2010-12-01

    The release of software attributes to users by software designers for the creation of user-designed forms is regarded as a producer-consumer collaboration, leading consumers to expend significant effort on a specific product. This article identifies such software/product attributes within online role-playing games and then explores how consumers' prior experience affects the evaluation of such attributes. In this article, product attributes comprise customized, content, and interactive externality-sensitive and complementary externality-sensitive attributes, with the value of each attribute being greater for experts than for novices. In Study 1, data were collected and analyzed for the purpose of identifying such features in online role-playing games. The results can also be generalized to convergent products, such as TV games that have been redesigned as online games or mobile games found in Study 2. For the introduction of a convergent product to be successful, our research suggests that the potential market-segment focus should be on knowledgeable consumers who accept such products more readily.

    The exercise pressor reflex arises from contracting skeletal muscle and is believed to play a role in evoking the cardiovascular responses to static exercise, effects that include increases in arterial pressure and heart rate. This reflex is believed to be evoked by the metabolic and mechanical stimulation of thin fiber muscle afferents. Lactic acid is known to be an important metabolic stimulus evoking the reflex. Until recently, the only antagonist for acid-sensitive ion channels (ASICs), the receptors to lactic acid, was amiloride, a substance that is also a potent antagonist for both epithelial sodium channels as well as voltage-gated sodium channels. Recently, a second compound, A-317567, has been shown to be an effective and selective antagonist to ASICs in vitro. Consequently, we measured the pressor responses to the static contraction of the triceps surae muscles in decerebrate cats before and after a popliteal arterial injection of A-317567 (10 mM solution; 0.5 ml). We found that this ASIC antagonist significantly attenuated by half (Pacid injection into the popliteal artery. In contrast, A-317567 had no effect on the pressor responses to tendon stretch, a pure mechanical stimulus, and to a popliteal arterial injection of capsaicin, which stimulated transient receptor potential vanilloid type 1 channels. We conclude that ASICs on thin fiber muscle afferents play a substantial role in evoking the metabolic component of the exercise pressor reflex.

    2016-11-01

    Symbiotic bacteria are a common feature of many animals, particularly invertebrates, from both aquatic and terrestrial habitats. These bacteria have increasingly been recognized as performing an important role in maintaining invertebrate health. Both ecto- and endoparasitic helminths have also been found to harbour a range of bacterial species which provide a similar function. The part symbiotic bacteria play in sustaining homeostasis of free-living invertebrates exposed to anthropogenic pressure (climate change, pollution), and the consequences to invertebrate populations when their symbionts succumb to poor environmental conditions, are increasingly important areas of research. Helminths are also susceptible to environmental stress and their symbiotic bacteria may be a key aspect of their responses to deteriorating conditions. This article summarizes the ecophysiological relationship helminths have with symbiotic bacteria and the role they play in maintaining a healthy parasite and the relevance of specific changes that occur in free-living invertebrate-bacteria interactions under anthropogenic pressure to helminths and their bacterial communities. It also discusses the importance of understanding the mechanistic sensitivity of helminth-bacteria relationships to environmental stress for comprehending the responses of parasites to challenging conditions.

  19. Perineuronal nets play a role in regulating striatal function in the mouse.

    Directory of Open Access Journals (Sweden)

    Hyunchul Lee

    Full Text Available The striatum is the primary input nucleus of the basal ganglia, a collection of nuclei that play important roles in motor control and associative learning. We have previously reported that perineuronal nets (PNNs, aggregations of chondroitin-sulfate proteoglycans (CSPGs, form in the matrix compartment of the mouse striatum during the second postnatal week. This period overlaps with important developmental changes, including the attainment of an adult-like gait. Here, we investigate the identity of the cells encapsulated by PNNs, characterize their topographical distribution and determine their function by assessing the impact of enzymatic digestion of PNNs on two striatum-dependent behaviors: ambulation and goal-directed spatial learning. We show PNNs are more numerous caudally, and that a substantial fraction (41% of these structures surrounds parvalbumin positive (PV+ interneurons, while approximately 51% of PV+ cells are ensheathed by PNNs. The colocalization of these structures is greatest in dorsal, lateral and caudal regions of the striatum. Bilateral digestion of striatal PNNs led to an increase in both the width and variability of hind limb gait. Intriguingly, this also resulted in an improvement in the acquisition rate of the Morris water maze. Together, these data show that PNNs are associated with specific elements of striatal circuits and play a key role in regulating the function of this important structure in the mouse.

    1990-09-01

    The effects of a thromboxane A2 (TxA2)-endoperoxide receptor antagonist, SQ 29548, on jejunal blood flow, oxygen uptake, and capillary filtration coefficient (Kfc) were determined in anesthetized dogs under resting conditions and during the presence of predigested food in the jejunal lumen in three series of experiments. In series 1, 2.0 micrograms intra-arterial administration of SQ 29548 was found to abolish completely the vasoconstrictor action of graded doses (0.05-2.0 micrograms) of intra-arterial injection of a TxA2-endoperoxide analogue, U44069. SQ 29548 (2.0 micrograms ia) per se did not significantly alter resting jejunal blood flow, oxygen uptake, capillary pressure, or Kfc. Before SQ 29548, placement of food plus bile into the jejunal lumen increased blood flow +42 +/- 9%, oxygen uptake +28 +/- 7%, and Kfc +24 +/- 6%. After SQ 29548, the food placement increased blood flow +37 +/- 8%, oxygen uptake +52 +/- 11%, and Kfc +63 +/- 20%. The food-induced increases in oxygen uptake and Kfc after SQ 29548 were significantly greater than those induced before the blocking of TxA2-endoperoxide receptors by SQ 29548. Our study indicates that endogenous thromboxane does not play a role in regulating jejunal blood flow, capillary filtration, and oxygen uptake under resting conditions. However, it plays a role in limiting the food-induced increases in jejunal oxygen uptake and capillary exchange capacity without influencing the food-induced hyperemia.

  4. Three members of the 6-cys protein family of Plasmodium play a role in gamete fertility.

    Directory of Open Access Journals (Sweden)

    Melissa R van Dijk

    2010-04-01

    Full Text Available The process of fertilization is critically dependent on the mutual recognition of gametes and in Plasmodium, the male gamete surface protein P48/45 is vital to this process. This protein belongs to a family of 10 structurally related proteins, the so called 6-cys family. To identify the role of additional members of this family in Plasmodium fertilisation, we performed genetic and functional analysis on the five members of the 6-cys family that are transcribed during the gametocyte stage of P. berghei. This analysis revealed that in addition to P48/45, two members (P230 and P47 also play an essential role in the process of parasite fertilization. Mating studies between parasites lacking P230, P48/45 or P47 demonstrate that P230, like P48/45, is a male fertility factor, consistent with the previous demonstration of a protein complex containing both P48/45 and P230. In contrast, disruption of P47 results in a strong reduction of female fertility, while males remain unaffected. Further analysis revealed that gametes of mutants lacking expression of p48/45 or p230 or p47 are unable to either recognise or attach to each other. Disruption of the paralog of p230, p230p, also specifically expressed in gametocytes, had no observable effect on fertilization. These results indicate that the P. berghei 6-cys family contains a number of proteins that are either male or female specific ligands that play an important role in gamete recognition and/or attachment. The implications of low levels of fertilisation that exist even in the absence of these proteins, indicating alternative pathways of fertilisation, as well as positive selection acting on these proteins, are discussed in the context of targeting these proteins as transmission blocking vaccine candidates.

    The rootless duckweed Wolffia globosa can accumulate and tolerate relatively large amounts of arsenic (As); however, the underlying mechanisms were unknown. W. globosa was exposed to different concentrations of arsenate with or without L-buthionine sulphoximine (BSO), a specific inhibitor of γ-glutamylcysteine synthetase. Free thiol compounds and As(III)–thiol complexes were identified and quantified using HPLC – high resolution ICP-MS – accurate mass ESI-MS. Without BSO, 74% of the As accumulated in the duckweed was complexed with phytochelatins (PCs), with As(III)–PC 4 and As(III)–PC 3 being the main species. BSO was taken up by the duckweed and partly deaminated. The BSO treatment completely suppressed the synthesis of PCs and the formation of As(III)–PC complexes, and also inhibited the reduction of arsenate to arsenite. BSO markedly decreased both As accumulation and As tolerance in W. globosa. The results demonstrate an important role of PCs in detoxifying As and enabling As accumulation in W. globosa. - Highlights: ► W. globosa can accumulate and tolerate relatively large amounts of arsenic. ► Majority of the As accumulated in W. globosa was complexed with phytochelatins (PCs). ► As(III)–PC 4 and As(III)–PC 3 are the main complex species. ► Complexation of arsenite with phytochelatins plays a key role in As tolerance and accumulation. - Complexation of arsenite with phytochelatins plays a key role in both arsenic tolerance and accumulation in the aquatic macrophyte Wolffia globosa.

    Microbial biofilms are tolerant to antibiotic treatment and therefore cause problematic infections. Knowledge about the molecular mechanisms underlying biofilm-associated antimicrobial tolerance will aid the development of antibiofilm drugs. Screening of a Streptococcus mutans transposon mutant library for genes that are important for biofilm-associated antimicrobial tolerance provided evidence that the dlt genes play a role in the tolerance of S. mutans biofilms towards gentamicin. The minimum bactericidal concentration for biofilm cells (MBC-B) for a dltA transposon mutant was eight-fold lower than that of the wild-type. The minimum bactericidal concentration for planktonic cells (MBC-P) was only slightly reduced, indicating that the mechanism involved in the observed antimicrobial tolerance has a predominant role specifically in biofilms. Experiments with a knockout dltA mutant and complemented strain confirmed that the dlt genes in S. mutans play a role in biofilm-associated tolerance to gentamicin. Confocal laser scanning microscopy analyses of biofilms grown on glass slides showed that the dltA mutant produced roughly the same amount of biofilm as the wild-type, indicating that the reduced antimicrobial tolerance of the dltA mutant is not due to a defect in biofilm formation. The products of the dlt genes have been shown to mediate alanylation of teichoic acids, and in accordance the dltA mutant showed a more negatively charged surface than the wild-type, which likely is an important factor in the reduced tolerance of the dltA mutant biofilms towards the positively charged gentamicin.

    Diabetic retinopathy is one of the leading causes of blindness. There are several risk factors, such as the duration of diabetes or glycemic control of the patient; however, several biochemical factors also alter the process. Our aim was to investigate the role of soluble E-selectin in the formation of diabetic retinopathy. Fifty-seven patients (37 female and 20 male, aged 61.71 ± 12.31 years) and 14 healthy control subjects (ten female and four male, aged 63.06 ± 10.46 years) were enrolled in the study. We measured the soluble E-selectin level in the plasma of patients by ELISA. All patients underwent careful ophthalmological examination, including ophthalmoscopy and color fundus photography, while diabetic retinopathy grading was performed in line with the 2012 classification of the American Academy of Ophthalmology (AAO). The soluble E-selectin level was significantly higher in patients with diabetes compared to controls (32.95 ng/ml vs. 26.55 ng/ml, p = 0.03). Dividing patients into groups by the presence of retinopathy, the E-selectin level was also significantly higher in the retinopathy group (p diabetic patients by the severity of retinopathy (groups A, B, and C, by the guidelines of the AAO), however, we did not find any significant difference in soluble E-selectin levels, although it tended to be higher in group B. An elevated E-selectin level can play a role in the development of diabetic retinopathy, but it does not seem to alter disease severity. However, glycemic control and the reduction of cardiovascular risk factors may also alter the level of E-selectin that might play a role in the prevention of diabetic retinopathy.

    Full Text Available Senataxin, mutated in the human genetic disorder ataxia with oculomotor apraxia type 2 (AOA2, plays an important role in maintaining genome integrity by coordination of transcription, DNA replication, and the DNA damage response. We demonstrate that senataxin is essential for spermatogenesis and that it functions at two stages in meiosis during crossing-over in homologous recombination and in meiotic sex chromosome inactivation (MSCI. Disruption of the Setx gene caused persistence of DNA double-strand breaks, a defect in disassembly of Rad51 filaments, accumulation of DNA:RNA hybrids (R-loops, and ultimately a failure of crossing-over. Senataxin localised to the XY body in a Brca1-dependent manner, and in its absence there was incomplete localisation of DNA damage response proteins to the XY chromosomes and ATR was retained on the axial elements of these chromosomes, failing to diffuse out into chromatin. Furthermore persistence of RNA polymerase II activity, altered ubH2A distribution, and abnormal XY-linked gene expression in Setx⁻/⁻ revealed an essential role for senataxin in MSCI. These data support key roles for senataxin in coordinating meiotic crossing-over with transcription and in gene silencing to protect the integrity of the genome.

    Full Text Available The G-protein coupled receptor 55 (GPR55 is activated by lysophosphatidylinositols and some cannabinoids. Recent studies found prominent roles for GPR55 in neuropathic/inflammatory pain, cancer and bone physiology. However, little is known about the role of GPR55 in CNS development and function. To address this question, we performed a detailed characterization of GPR55 knockout mice using molecular, anatomical, electrophysiological, and behavioral assays. Quantitative PCR studies found that GPR55 mRNA was expressed (in order of decreasing abundance in the striatum, hippocampus, forebrain, cortex, and cerebellum. GPR55 deficiency did not affect the concentrations of endocannabinoids and related lipids or mRNA levels for several components of the endocannabinoid system in the hippocampus. Normal synaptic transmission and short-term as well as long-term synaptic plasticity were found in GPR55 knockout CA1 pyramidal neurons. Deleting GPR55 function did not affect behavioral assays assessing muscle strength, gross motor skills, sensory-motor integration, motor learning, anxiety or depressive behaviors. In addition, GPR55 null mutant mice exhibited normal contextual and auditory-cue conditioned fear learning and memory in a Pavlovian conditioned fear test. In contrast, when presented with tasks requiring more challenging motor responses, GPR55 knockout mice showed impaired movement coordination. Taken together, these results suggest that GPR55 plays a role in motor coordination, but does not strongly regulate CNS development, gross motor movement or several types of learned behavior.

    Full Text Available The cytotoxin-associated gene (Cag pathogenicity island is a strain-specific constituent of Helicobacter pylori (H. pylori that augments cancer risk. CagA translocates into the cytoplasm where it stimulates cell signaling through the interaction with tyrosine kinase c-Met receptor, leading cellular proliferation. Identified as a potential gastric stem cell marker, cluster-of-differentiation (CD CD44 also acts as a co-receptor for c-Met, but whether it plays a functional role in H. pylori-induced epithelial proliferation is unknown. We tested the hypothesis that CD44 plays a functional role in H. pylori-induced epithelial cell proliferation. To assay changes in gastric epithelial cell proliferation in relation to the direct interaction with H. pylori, human- and mouse-derived gastric organoids were infected with the G27 H. pylori strain or a mutant G27 strain bearing cagA deletion (∆CagA::cat. Epithelial proliferation was quantified by EdU immunostaining. Phosphorylation of c-Met was analyzed by immunoprecipitation followed by Western blot analysis for expression of CD44 and CagA. H. pylori infection of both mouse- and human-derived gastric organoids induced epithelial proliferation that correlated with c-Met phosphorylation. CagA and CD44 co-immunoprecipitated with phosphorylated c-Met. The formation of this complex did not occur in organoids infected with ∆CagA::cat. Epithelial proliferation in response to H. pylori infection was lost in infected organoids derived from CD44-deficient mouse stomachs. Human-derived fundic gastric organoids exhibited an induction in proliferation when infected with H. pylori that was not seen in organoids pre-treated with a peptide inhibitor specific to CD44. In the well-established Mongolian gerbil model of gastric cancer, animals treated with CD44 peptide inhibitor Pep1, resulted in the inhibition of H. pylori-induced proliferation and associated atrophic gastritis.

    Light is a key stimulus for plant biological functions, several of which are controlled by light-activated kinases known as phototropins, a group of kinases that contain two light-sensing domains (LOV, Light-Oxygen-Voltage domains) and a C-terminal serine/threonine kinase domain. The second sensory domain, LOV2, plays a key role in regulating kinase enzymatic activity via the photochemical formation of a covalent adduct between a LOV2 cysteine residue and an internally-bound flavin mononucleotide (FMN) chromophore. Subsequent conformational changes in LOV2 lead to the unfolding of a peripheral Jα helix, and ultimately, phototropin kinase activation. To date, the mechanism coupling bond formation and helix dissociation has remained unclear. Previous studies found that a conserved glutamine residue (Q513 in the Avena sativa phototropin 1 LOV2 (AsLOV2) domain) switches its hydrogen-bonding pattern with FMN upon light stimulation. Located in the immediate vicinity of the FMN binding site, this Gln residue is provided by the Iβ strand that interacts with the Jα helix, suggesting a route for signal propagation from the core of the LOV domain to its peripheral Jα helix. To test whether Q513 plays a key role in tuning the photochemical and transduction properties of AsLOV2, we designed two point mutations, Q513L and Q513N, and monitored the effects on the chromophore and protein using a combination of UV-visible absorbance and circular dichroism spectroscopy, limited proteolysis, and solution NMR. The results show that these mutations significantly dampen the changes between the dark and lit state AsLOV2 structures, leaving the protein in a pseudo-dark state (Q513L) or a pseudo-lit state (Q513N) conformation. Further, both mutations changed the photochemical properties of this receptor, particularly the lifetime of the photoexcited signaling states. Together, these data establish that this residue plays a central role in both spectral tuning and signal propagation from

    Tissue growth and remodeling are known to govern mechanical homeostasis in biological tissue, but their relative contributions to homeostasis remain unclear. Here, we use mechanical models, fueled by experimental findings, to demonstrate that growth and remodeling have different effects on heart valve stretch homeostasis during physiological postnatal development. Two developmental stages were considered: early-stage (from infant to adolescent) and late-stage (from adolescent to adult) development. Our models indicated that growth and remodeling play opposing roles in preserving tissue stretch and with time. During early-stage development, excessive tissue stretch was decreased by tissue growth and increased by remodeling. In contrast, during late-stage development tissue stretch was decreased by remodeling and increased by growth. Our findings contribute to an improved understanding of native heart valve adaptation throughout life, and are highly relevant for the development of tissue-engineered heart valves.

    A large online community has recently formed around autonomous sensory meridian response (ASMR), a pleasant and poorly understood somatic reaction to specific interpersonal triggers. Its web-based manifestations include a variety of amateur videos designed to elicit the reaction, many of which feature protracted imitations of a clinician's physical exam. This analysis considers through a literary lens the proximity of this phenomenon to clinical diagnostics, focusing in particular on characterizations of spiritual isolation elaborated in Love in the Ruins (1971), the third novel by physician-writer Walker Percy (1916-1990). Within this speculative framework, the tendency to derive pleasure from clinical milieus, real or constructed, may be interpreted as a quality particular to the postmodern psyche. Viewing web-based clinical role-play in light of Percy's writing also underscores the possibility that routine diagnostic assessments may have independent therapeutic implications.

    Activation of caspase-11 by some Gram-negative bacteria triggers the caspase-1/interleukin 1β (IL-1β) pathway, independent of canonical inflammasomes. Acinetobacter baumannii is a Gram-negative, conditionally pathogenic bacterium that can cause severe pulmonary infection in hospitalized patients. A. baumannii was revealed to activate canonical and noncanonical inflammasome pathways in bone marrow-derived macrophages (BMDMs). Pulmonary infection of caspase-11 -/- mice with A. baumannii showed that caspase-11 deficiency impaired A. baumannii clearance, exacerbated pulmonary pathological changes, and enhanced susceptibility to A. baumannii These data indicate that the caspase-11-mediated innate immune response plays a crucial role in defending against A. baumannii .

    Massive multiplayer online role-playing games (MMORPGs) have been very popular in the past few years. The profit of an MMORPG company is proportional to how many users registered, and the instant number of online avatars is a key factor to assess how popular an MMORPG is. We use the online-offline logs on an MMORPG server to reconstruct the instant number of online avatars per second and investigate its statistical properties. We find that the online avatar number exhibits one-day periodic behavior and clear intraday pattern, the fluctuation distribution of the online avatar numbers has a leptokurtic non-Gaussian shape with power-law tails, and the increments of online avatar numbers after removing the intraday pattern are uncorrelated and the associated absolute values have long-term correlation. In addition, both time series exhibit multifractal nature.

  18. Does Islam play a role in anti-immigrant sentiment? An experimental approach.

    Are Muslim immigrants subjected to targeted opposition (i.e., Islamophobia) on their pathway to US citizenship? Using a list experiment and a representative sample of the US population, we compare explicit and implicit opposition to Muslim and Christian immigrants. We find that Muslim immigrants, relative to Christian immigrants, experience greater explicit resistance. However, when social desirability bias is taken into account via the list experiment, we find that opposition to Christian and Muslim immigrants is the same. The explanation is that respondents conceal a significant amount of opposition to Christian immigrants. Muslim immigrants, on the other hand, are afforded no such protection. We find that religiosity or denomination do not play a significant role in determining implicit or explicit opposition. We conclude that Islamophobia, which is only explicitly expressed, is best understood as reflective of social desirability bias from which Muslim immigrants do not benefit.

  19. Lectins in fish skin: do they play a role in host-monogenean interactions?

    Mucus samples from rainbow trout skin with or without infections by Gyrodactylus derjavini were tested for the presence of lectins reacting with mannose, galactose and lactose. The samples inhibited the binding of biotinylated lectins (from Canavalia ensiformis, Artocarpus integrifolia and Erythrina corallodendron, respectively) to microtitre plates with covalently bound carbohydrates (mannopyranoside, galactopyranoside and lactose, respectively). However, the inhibition of C. ensiformis and A. integrifolia lectins was slightly greater when mucus from infected (but recovering) fish was used, suggesting an increase of mannose and galactose binding lectins in fish skin exposed to parasites. As mannose, galactose and lactose are present on the glycocalyx of Gyrodactylus derjavini, it is suggested that lectins could play a dual role in interactions between fish hosts and their monogenean parasites. Thus, recognition between parasite and host and also host responses towards parasite infections could both, at least partly, involve carbohydrate-lectin binding.
