  2. Summary of group discussions

    International Nuclear Information System (INIS)

    2009-01-01

    A key aspect of the workshop was the interaction and exchange of ideas and information among the 40 participants. To facilitate this activity the workshop participants were divided into five discussions groups. These groups reviewed selected subjects and reported back to the main body with summaries of their considerations. Over the 3 days the 5 discussion groups were requested to focus on the following subjects: the characteristics and capabilities of 'good' organisations; how to ensure sufficient resources; how to ensure competence within the organisation; how to demonstrate organisational suitability; the regulatory oversight processes - including their strengths and weaknesses. A list of the related questions that were provided to the discussion groups can be found in Appendix 3. Also included in Appendix 3 are copies of the slides the groups prepared that summarised their considerations

    The Understanding Research series focuses on the process of writing up social research. The series is broken down into three categories: Understanding Statistics, Understanding Measurement, and Understanding Qualitative Research. The books provide researchers with guides to understanding, writing, and evaluating social research. Each volume demonstrates how research should be represented, including how to write up the methodology as well as the research findings. Each volume also reviews how to appropriately evaluate published research. Focus Group Discussions addresses the challenges associated with conducting and writing focus group research. It provides detailed guidance on the practical and theoretical considerations in conducting focus group discussions including: designing the discussion guide, recruiting participants, training a field team, moderating techniques and ethical considerations. Monique Hennink describes how a methodology section is read and evaluated by others, such as journal reviewers or ...

    The aim of this audit was to determine the effectiveness of large group tutorials for teaching neurology to medical students. Students were asked to complete a questionnaire rating their confidence on a ten point Likert scale in a number of domains in the undergraduate education guidelines from the Association of British Neurologists (ABN). We then arranged a series of interactive large group tutorials for the class and repeated the questionnaire one month after teaching. In the three core domains of neurological: history taking, examination and differential diagnosis, none of the students rated their confidence as nine or ten out of ten prior to teaching. This increased to 6% for history taking, 12 % in examination and 25% for differential diagnosis after eight weeks of tutorials. This audit demonstrates that in our centre, large group tutorials were an effective means of teaching, as measured by the ABN guidelines in undergraduate neurology.

    2003-01-01

    The popularization of problem-based learning (PBL) has drawn attention to the motivational and cognitive skills necessary for medical students in group learning. This study identifies the effect of motivational and cognitive factors on group productivity of PBL tutorial groups. A self-administered questionnaire was completed by 115 students at the end of PBL tutorials for 4 themes. The questionnaire explored student perceptions about effect of motivation, cohesion, sponging, withdrawal, interaction, and elaboration on group productivity. We further analyzed (a) differences in perceptions between male and female students, (b) effect of "problems," and (c) effect of student progress over time on group productivity. There were linear relations between a tutorial group's success and the factors studied. Significant differences were noted between male and female student groups. Students and tutors need to recognize symptoms of ineffective PBL groups. Our study emphasizes the need to take into account cultural issues in setting ground rules for PBL tutorials.

    2010-01-01

    In October 2005, a group of astronomy faculty and graduate students met to establish departmental support for participants in the UM Center for Teaching Excellence University Teaching and Learning Program. This program seeks to increase graduate students’ understanding of effective teaching methods, awareness of student learning, and appreciation of education as a scholarly pursuit. Our group has facilitated the submission of successful graduate student educational development grant proposals to the Center for Teaching Excellence (CTE). Completion of the CTE program results in a notation on the graduate student's transcript. Our discussion group met monthly during the first two years. The Astronomy Education Review, The Physics Teacher, The Washington Post, The Chronicle of Higher Education, and National Research Council publications were used to provide background for discussion. Beginning in 2007, the group began sponsoring monthly astronomy education lunches during the academic year to which the entire department was invited. Over the past two years, speakers have included graduate students, faculty, and guests, such as Jay Labov from the National Research Council. Topics have included the Astronomy Diagnostic Test, intelligent design versus evolution, active learning techniques, introducing the use of lecture tutorials, using effective demonstrations, confronting student misconceptions, engagement through clickers (or cards), and fostering critical thinking with ranking tasks. The results of an informal evaluation will be presented.

    Interactive communication on the Internet, as illustrated by the e-mail-based breast cancer discussion group, provides an alternative to the telephone, the fax machine and regular mail, and is a resource for communications research, the potential of which is only beginning to be appreciated. At least some of the messages posted to such discussion groups could be regarded as a form of "journaling". Such messages are eminently suitable for qualitative data analysis.

  12. How to conduct focus groups: researching group priorities through discussion.

    Science.gov (United States)

    1992-01-01

    Focus groups serve to uncover priorities and beliefs of a target group, but health project designers do not always take the time to seek this information beforehand. Focus groups also allow various local subgroups to communicate their concerns before the project starts. Focus groups can also breed ideas and dialogue that individual interviews cannot and they provide baseline information so managers can determine if attitudes or priorities have resulted from the project. Diverse people have different beliefs, e.g., women who have young children view oral rehydration therapy differently from women with no children. Project designers can use these basic differences to arrive at some conclusions about general attitudes. Focus group facilitators should have a discussion outline to help keep the group on the topic of concern. They should limit sessions to 60-90 minutes. Each focus groups should include 8-10 people. It is important to have members of various community subgroups in each group. Yet group designers should be careful not to include within the same group, those who may intimidate other people in the group, e.g., in situations where farmers depend on middlemen, farmers may not be open if middlemen are also in the focus group. Facilitators should launch each session with an attempt to encourage the members to be open and to feel comfortable. For example, in Malawi, a facilitator leads her focus group discussions with songs. Stories are another icebreaker. It is important that all focus groups centering around a certain project discuss the same topics. Facilitators need to stress to the group that all discussions are to be kept confidential. The designers should also carefully word the questions so that facilitators will not impart their bias. Facilitators should not direct the group to certain conclusions, but instead keep the discussions focused.

    2015-04-01

    It is increasingly common in physics classes for students to work together to solve problems and perform laboratory experiments. When students work together, they need to negotiate the roles and decision making within the group. We examine how a large group of students negotiates authority as part of their two week summer College Readiness Program at Rochester Institute of Technology. The program is designed to develop metacognitive skills in first generation and Deaf and hard-of-hearing (DHH) STEM undergraduates through cooperative group work, laboratory experimentation, and explicit reflection exercises. On the first full day of the program, the students collaboratively developed a sign for the word ``metacognition'' for which there is not a sign in American Sign Language. This presentation will focus on three aspects of the ensuing discussion: (1) how the instructor communicated expectations about decision making; (2) how the instructor promoted student-driven decision making rather than instructor-driven policy; and (3) one student's shifts in decision making behavior. We conclude by discussing implications of this research for activity-based physics instruction.

    2018-03-01

    The Focus Group Discussion (FGD) activity in Mathematical Physics learning has helped students perform the stages of problem solving reflectively. The FGD implementation was conducted to explore the problems and find the right strategy to improve the students' ability to solve the problem accurately which is one of reflective thinking component that has been difficult to improve. The research method used is descriptive qualitative by using single subject response in Physics student. During the FGD process, one student was observed of her reflective thinking development in solving the physics problem. The strategy chosen in the discussion activity was the Cognitive Apprenticeship-Instruction (CA-I) syntax. Based on the results of this study, it is obtained the information that after going through a series of stages of discussion, the students' reflective thinking skills is increased significantly. The scaffolding stage in the CA-I model plays an important role in the process of solving physics problems accurately. Students are able to recognize and formulate problems by describing problem sketches, identifying the variables involved, applying mathematical equations that accord to physics concepts, executing accurately, and applying evaluation by explaining the solution to various contexts.

    2014-01-01

    The analytic hierarchy process (AHP) has been increasingly applied as a technique for multi-criteria decision analysis in healthcare. The AHP can aid decision makers in selecting the most valuable technology for patients, while taking into account multiple, and even conflicting, decision criteria. This tutorial illustrates the procedural steps of the AHP in supporting group decision making about new healthcare technology, including (1) identifying the decision goal, decision criteria, and alternative healthcare technologies to compare, (2) structuring the decision criteria, (3) judging the value of the alternative technologies on each decision criterion, (4) judging the importance of the decision criteria, (5) calculating group judgments, (6) analyzing the inconsistency in judgments, (7) calculating the overall value of the technologies, and (8) conducting sensitivity analyses. The AHP is illustrated via a hypothetical example, adapted from an empirical AHP analysis on the benefits and risks of tissue regeneration to repair small cartilage lesions in the knee.

  17. Synthesis of the working group discussions

    International Nuclear Information System (INIS)

    2003-01-01

    The workshop was an important step in the establishment of a strategy to review the part of SKB's safety case that is devoted to the demonstration of the isolation function of a future spent fuel repository. The emphasis was on identification rather than resolution of issues in this workshop synthesis. Subsequent steps therefore have to be taken within the Swedish regulatory bodies to follow up on this report and suggest activities within the regulators research programmes, as well as organise more detailed issue evaluation for different experts group. Ongoing and planned activities within the SKB programme that are related to the issues identified in this report would have to be reviewed in detail. The great emphasis of isolation of spent nuclear fuel rather than, e.g., radionuclide retardation and dilution, featured in the SR97 performance assessment, suggests that the Swedish regulators have to be prepared to review this part of the coming PAs in greater detail. The specific features of the workshop that contributed to the rather comprehensive description of issues relevant for future licensing activities are: The combined consideration of the areas of the copper canister and bentonite buffer, the assessment of both chemical and mechanical aspects of EBS and canister integrity, the use of a published comprehensive performance assessment (SR-97) as a basis for discussions, the active participation by SKB providing additional information on recent developments. There is an educational value for external consultants and researchers, as well as SKI staff, in addressing the broad subject areas relevant for the EBS isolation function. However, a broad coverage to some extent necessitates rather superficial view of the various issues under consideration. It should be noted that the descriptions in this synthesis can by no means be regarded as fully comprehensive, and that additional key issues may be identified in the SKB programme as well as future regulatory

  18. On the Multilevel Nature of Meta-Analysis: A Tutorial, Comparison of Software Programs, and Discussion of Analytic Choices.

    Pastor, Dena A; Lazowski, Rory A

    2018-01-01

    The term "multilevel meta-analysis" is encountered not only in applied research studies, but in multilevel resources comparing traditional meta-analysis to multilevel meta-analysis. In this tutorial, we argue that the term "multilevel meta-analysis" is redundant since all meta-analysis can be formulated as a special kind of multilevel model. To clarify the multilevel nature of meta-analysis the four standard meta-analytic models are presented using multilevel equations and fit to an example data set using four software programs: two specific to meta-analysis (metafor in R and SPSS macros) and two specific to multilevel modeling (PROC MIXED in SAS and HLM). The same parameter estimates are obtained across programs underscoring that all meta-analyses are multilevel in nature. Despite the equivalent results, not all software programs are alike and differences are noted in the output provided and estimators available. This tutorial also recasts distinctions made in the literature between traditional and multilevel meta-analysis as differences between meta-analytic choices, not between meta-analytic models, and provides guidance to inform choices in estimators, significance tests, moderator analyses, and modeling sequence. The extent to which the software programs allow flexibility with respect to these decisions is noted, with metafor emerging as the most favorable program reviewed.

    Graduate medical students of India are taught Biochemistry by didactic lectures and they hardly get any opportunity to clarify their doubts and reinforce the concepts which they learn in these lectures. We used a combination of teaching-learning (T-L) methods (open book assignment followed by group tutorials) to study their efficacy in improving the learning outcome. About 143 graduate medical students were classified into low (75%: group 3, n = 46) achievers, based on their internal assessment marks. After the regular teaching module on the topics "Vitamins and Enzymology", all the students attempted an open book assignment without peer consultation. Then all the students participated in group tutorials. The effects on the groups were evaluated by pre and posttests at the end of each phase, with the same set of MCQs. Gain from group tutorials and overall gain was significantly higher in the low achievers, compared to other groups. High and medium achievers obtained more gain from open book assignment, than group tutorials. The overall gain was significantly higher than the gain obtained from open book assignment or group tutorials, in all three groups. All the three groups retained the gain even after 1 week of the exercise. Hence, optimal use of novel T-L methods (open book assignment followed by group tutorials) as revision exercises help in strengthening concepts in Biochemistry in this oft neglected group of low achievers in graduate medical education. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):321-325, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

    This article describes one librarian's experiences with creating, promoting, and assessing online library tutorials. Tutorials were designed to provide on-demand and accessible library instruction to nursing students at Michigan State University. Topics for tutorials were chosen based on the librarian's liaison experiences and suggestions from nursing faculty. The tutorials were created using Camtasia and required the application of several tools and techniques. Tutorials were promoted through Web pages, the ANGEL course management system, blog posts, librarian interactions, e-mails, and more. In order to assess the tutorials' perceived effectiveness, feedback was gathered using a short survey. Future plans for the nursing tutorials project are also discussed.

    2018-01-01

    In many domains of life, business and management, numerous problems are addressed by small groups of individuals engaged in face-to-face discussions. While research in social psychology has a long history of studying the determinants of small group performances, the internal dynamics that govern a group discussion are not yet well understood. Here, we rely on computational methods based on network analyses and opinion dynamics to describe how individuals influence each other during a group discussion. We consider the situation in which a small group of three individuals engages in a discussion to solve an estimation task. We propose a model describing how group members gradually influence each other and revise their judgments over the course of the discussion. The main component of the model is an influence network-a weighted, directed graph that determines the extent to which individuals influence each other during the discussion. In simulations, we first study the optimal structure of the influence network that yields the best group performances. Then, we implement a social learning process by which individuals adapt to the past performance of their peers, thereby affecting the structure of the influence network in the long run. We explore the mechanisms underlying the emergence of efficient or maladaptive networks and show that the influence network can converge towards the optimal one, but only when individuals exhibit a social discounting bias by downgrading the relative performances of their peers. Finally, we find a late-speaker effect, whereby individuals who speak later in the discussion are perceived more positively in the long run and are thus more influential. The numerous predictions of the model can serve as a basis for future experiments, and this work opens research on small group discussion to computational social sciences.

    2006-03-01

    Full Text Available Abstract Background The completeness of preferences is assumed as one of the axioms of expected utility theory but has been subject to little empirical study. Methods Fifteen non-health professionals was recruited and familiarised with the standard gamble technique. The group then met five times over six months and preferences were elicited independently on 41 scenarios. After individual valuation, the group discussed the scenarios, following which preferences could be changed. Changes made were described and summary measures (mean and median before and after discussion compared using paired t test and Wilcoxon Signed Rank Test. Semi-structured telephone interviews were carried out to explore attitudes to discussing preferences. These were transcribed, read by two investigators and emergent themes described. Results Sixteen changes (3.6% were made to preferences by seven (47% of the fifteen members. The difference between individual preference values before and after discussion ranged from -0.025 to 0.45. The average effect on the group mean was 0.0053. No differences before and after discussion were statistically significant. The group valued discussion highly and suggested it brought four main benefits: reassurance; improved procedural performance; increased group cohesion; satisfying curiosity. Conclusion The hypothesis that preferences are incomplete cannot be rejected for a proportion of respondents. However, brief discussion did not result in substantial number of changes to preferences and these did not have significant impact on summary values for the group, suggesting that incompleteness, if present, may not have an important effect on cost-utility analyses.

Teacher as a captain of class has the right to choose type of method used in the classroom for sake of students’ improvement. This study was designed as an attempt to help Master Students from a well established private university improve their reading comprehension skill through small group discussion. This study was participated by 30 students, later divided into two classes and served differently as an experimental group for the class A and a control group for the class B. Referring to the final data analysis of the study, it is found that there is an improving learning achievement in the experimental group, indicated by higher performance of posttest (20.333 than the pretest. Apart from this, further analysis was also conducted to find out whether or not small group discussion was able to show better performance than another teaching method applied in another different class. Based on the result of statistical calculation, it shows that small group discussion got better result 12.334 than that of another group. As a result, some suggestions were made by referring to result of the study.

    2013-06-01

    Full Text Available The aim of this study was to examine how men who have perpetrated violence toward their partners and participated in batterer group talked about being a father and how they perceived their own fatherhood. The discussion in the group was analyzed qualitatively by using the methods of content analysis. In traditional fatherhood, they talked about avoidant, passiveness, distant, indifference, and authoritative controlling ways of acting. These men also created an image of themselves as active and caring fathers, thus including empathy and nurture in the concept of fatherhood. This new fatherhood was considered an achieved goal and an objective for the men as being a father. Talking about fatherhood in these groups is important as fatherhood and relations to children are both an important motivator toward nonviolence.

    2005-12-01

    The aim of this paper is to identify and discuss the ethical considerations that have confronted and challenged the research team when researchers facilitate conversations using private electronic mail discussion lists. The use of electronic mail group conversations, as a collaborative data generation method, remains underdeveloped in nursing. Ethical challenges associated with this approach to data generation have only begun to be considered. As receipt of ethics approval for a study titled; 'Describing transition with people who live with chronic illness' we have been challenged by many ethical dilemmas, hence we believe it is timely to share the issues that have confronted the research team. These discussions are essential so we can understand the possibilities for research interaction, communication, and collaboration made possible by advanced information technologies. Our experiences in this study have increased our awareness for ongoing ethical discussions about privacy, confidentiality, consent, accountability and openness underpinning research with human participants when generating data using an electronic mail discussion group. We describe how we work at upholding these ethical principles focusing on informed consent, participant confidentiality and privacy, the participants as threats to themselves and one another, public-private confusion, employees with access, hackers and threats from the researchers. A variety of complex issues arise during cyberspace research that can make the application of traditional ethical standards troublesome. Communication in cyberspace alters the temporal, spatial and sensory components of human interaction, thereby challenging traditional ethical definitions and calling to question some basic assumptions about identity and ones right to keep aspects of it confidential. Nurse researchers are bound by human research ethics protocols; however, the nature of research by electronic mail generates moral issues as well as ethical

Research has shown, for instance, that students are using their mobile phones in classroom settings, a practice that holds both potential advantages and disadvantages. In group work, these interactions may have consequences for group dynamics in that orienting to a mobile phone can display a shift in an individual’s attention to the group. The current essay details a research project conducted on prob...

    van Veggel, Nieky; Amory, Jonathan

    2014-01-01

    Students embarking on a bioscience degree course, such as Animal Science, often do not have sufficient experience in mathematics. However, mathematics forms an essential and integral part of any bioscience degree and is essential to enhance employability. This paper presents the findings of a project looking at the effect of mathematics tutorials on a cohort of first year animal science and management students. The results of a questionnaire, focus group discussions and academic performance analysis indicate that small group tutorials enhance students' confidence in maths and improve students' academic performance. Furthermore, student feedback on the tutorial programme provides a deeper insight into student experiences and the value students assign to the tutorials.

  11. Assessing the flexibility of research-based instructional strategies: Implementing tutorials in introductory physics in the lecture environment

    Science.gov (United States)

    Kryjevskaia, Mila; Boudreaux, Andrew; Heins, Dustin

    2014-03-01

    Materials from Tutorials in Introductory Physics, originally designed and implemented by the Physics Education Group at the University of Washington, were used in modified form as interactive lectures under conditions significantly different from those suggested by the curriculum developers. Student learning was assessed using tasks drawn from the physics education research literature. Use of tutorials in the interactive lecture format yielded gains in student understanding comparable to those obtained through the canonical tutorial implementation at the University of Washington, suggesting that student engagement with the intellectual steps laid out in the tutorials, rather than the specific strategies used in facilitating such engagement, plays the central role in promoting student learning. We describe the implementation details and assessment of student learning for two different tutorials: one focused on mechanical waves, used at North Dakota State University, and one on Galilean relativity, used at Western Washington University. Also discussed are factors that may limit the generalizability of the results.

Thework methodology has been periodically evaluated and rened in order to overcome identied pro-blems. Thus, the objective of this study was to evaluate the Tutorial Program based on the stu-dentsachievement, to show implemented modications and proposed alternatives to adjust methodo-logies. The student-nal-grades were obtained from UFV les. Questionnaires were applied to thePrograms students at the end of each semester. Suggestions and criticism from tutors and coordinatingprofessors were discussed at weekly meetings. Along six semesters (2001-2003, a leveling o of thetutorial students was observed with the attending students (S, minimum of 75% attendance, averagegrade 71.3 that got grades close to the average of no-tutorial students (average grade 71.5. For thetutorial students with attendance below the required minimum (N, the average grade was 58.8. Thefailure rate for grade S students (7.4% was lower then that for no-tutorial students (9.9% and forgrade N students (27.9%. Based on the lled out questionnaire from tutorial students, we observeas follows: 96.7% stated that it is eective to participate in the Program and 79.9% modied theirstudy approach.

  14. The communication of social stereotypes: the effects of group discussion and information distribution on stereotypic appraisals.

    Science.gov (United States)

    Brauer, M; Judd, C M; Jacquelin, V

    2001-09-01

    Stereotypes are fundamentally social constructs, formulated and modified through discussion and interaction with others. The present studies examined the impact of group discussion on stereotypes. In both studies, groups of participants discussed their impressions about a hypothetical target group after having read behaviors performed by target group members. These behaviors included both stereotypic and counterstereotypic examples, and the distribution of these behaviors varied across discussion group members. In some groups only 1 member knew of the counterstereotypic behaviors; in other groups this information was distributed across all group members. In general, discussion led to a polarization of the target group stereotypes, but this effect was lessened when the counterstereotypic behaviors were concentrated in 1 group member. In this case, these counterstereotypic behaviors were discussed more and retained better.

  16. The influence of group discussion on performance judgments: rating accuracy, contrast effects, and halo.

    Palmer, Jerry K; Loveland, James M

    2008-03-01

    The authors investigated the effect of group discussion, such as may occur formally in panel interview scenarios, assessment centers, or 360-degree feedback situations, on judgments of performance. Research on group polarization suggests that the effect of group discussion combined with raters' preexisting impressions of ratees or interviewees should result in an extremitization of impressions. Thus, the authors hypothesized that group discussion would (a) make ratings less accurate, (b) polarize impressions that were already good or poor as reflected by greater contrast effects, and (c) increase positive halo. Results indicated that group discussion resulted in less accurate ratings and greater contrast effects. Additional analyses suggested that group discussion increased positive halo. The authors discuss implications for research on group or panel judgments.

    2014-02-01

    Full Text Available This paper analyzes the terminology in the Internet social networks tutorials. A tutorial is a specialized text, full of terms, aiming to teach an individual or group of individuals who need some guidelines to operationalize a computerized tool, such as a social network. It is necessary to identify linguistic and terminological characteristics from the specialized lexical units in this digital genre. Social networks terminology is described and exemplified here. The results show that it is possible to refer to two specific terminologies in tutorials which help to determine the terminological profile of the thematic area, specifically from the point of view of denomination.

  11. Effects of communication strategy training on EFL students’ performance in small-group discussions

    Directory of Open Access Journals (Sweden)

    Stuart Benson

    2013-10-01

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

    - Facebook (Menlo Park, California) is one of many online sites that provide potential educational tools for pathologists. We have each founded Facebook groups dedicated to anatomic pathology, in which members can share cases, ask questions, and contribute to discussions. - To report our experiences in founding and maintaining these Facebook groups and to characterize the contributed content. - We circulated a survey among the group founders, then compiled and analyzed the responses. - The groups varied in membership and in the quality of member contribution. Most posts were of pathology cases, although other topics (such as research articles) were also shared. All groups remained active and received posts from users all over the world, although all groups had many noncontributing members and received unwanted messages (which were screened and removed). Most founders were glad they had founded the groups because they provided an opportunity to both teach and learn. - Each analyzed Facebook group had a different character, and some downsides exist, but the groups all provided a no-cost way for pathologists and others across the world to interact online with many colleagues.

    A qualitative method using focus group discussions (FGDs) was applied in this study to identify people's perceptions on newspaper reporting pertaining to the Southern Separatist Movement (SSM) by different Yemeni newspapers. This paper also looked into the attitudes towards the movement and the popularity of the issue of Yemeni unification. Five FGD groups with a total of 30 participants discussed the subject and some other aspects related to it. The findings of the focu19 groups showed that the southern crisis and SSM had shaken the people's trust on the current form of the unity. The discussion with the groups revealed that media in general and the selected four papers from various political persuasions have no credibility and objectivity, but these papers are trying to instill democratic values which is consistent with their ideology, which have a serious impact on the value of liberal democracy. The participants assured that reporting on the southern cause and the SSM indicated the absence of professional journalism in the media and the political discourse in general.

    Full Text Available This paper reports on a case study of the use of Facebook in learning and teaching in higher education. Facebook was used as a venue for online discussion to support the existing Learning Management System (in this case Blackboard in the unit Internet Collaboration and Organisation as part of the Internet Communications degree taught fully online through Open Universities Australia (OUA. Students’ posts to both Facebook and the Blackboard discussion forum were analysed for content, length, and when throughout the study period they were posted. This is significant as much of the previous work in this area has relied on students self-reporting, rather than direct observation of student behaviour. These results were then compared to earlier instances of the same unit that ran within the previous twelve months, one fully online with OUA only using the Blackboard discussion group, and a second taught at Curtin University with both blended learning for students at the University’s Bentley campus as well as fully online for external students, that utilised both Blackboard and Facebook. The results show that Facebook greatly increases the level of student activity in online discussions, both absolutely and in the level of sustained activity across the unit’s study period. Facebook groups also had a different pattern of content from Blackboard. In Blackboard discussion is more focused on the set unit learning content, in Facebook students were using the groups to discuss administration and assignments and also bring in additional material from outside the units set learning materials. Facebook posts, while more sustained over the semester, were shorter in length. This study found that the addition of a Facebook discussion forum does not noticeably impact on the use of Blackboard’s discussion forum, but rather adds a new dimension to the mix of online interaction. The paper concludes that there is value in using both of these forums for student

    The growing body of evidence attesting to the effectiveness of clinical male circumcision in the prevention of HIV/AIDS transmission is prompting the majority of sub-Saharan African governments to move towards the adoption of voluntary medical male circumcision (VMMC). Even though it is recommended to consider collaboration with traditional male circumcision (TMC) providers when planning for VMMC, there is limited knowledge available about the TMC landscape and traditional beliefs. During 2010-11 over 25 focus group discussions (FGDs) were held with clan leaders, traditional cutters, and their assistants to understand the practice of TMC in four ethnic groups in Uganda. Cultural significance and cost were among the primary reasons cited for preferring TMC over VMMC. Ethnic groups in western Uganda circumcised boys at younger ages and encountered lower rates of TMC related adverse events compared to ethnic groups in eastern Uganda. Cutting styles and post-cut care also differed among the four groups. The use of a single razor blade per candidate instead of the traditional knife was identified as an important and recent change. Participants in the focus groups expressed interest in learning about methods to reduce adverse events. This work reaffirmed the strong cultural significance of TMC within Ugandan ethnic groups. Outcomes suggest that there is an opportunity to evaluate the involvement of local communities that still perform TMC in the national VMMC roll-out plan by devising safer, more effective procedures through innovative approaches.

    Generally, Faculty of Medicine of Udayana University applied Small Group Discussion (SGD) in its learning process. If group problem solving succeeds, each individual of the group will individually succeed. However, the success is also determined by each individual’s level of psychological well-being. When the students are in the high level of wellbeing, they will feel comfortable in small group discussion, and teamwork will be effective. Therefore, it is needed to conduct a research which investigates how psychological factors, such as traits, needs, cognitive, and social intelligence, influence students’ wellbeing in performing SGD. This research is also initiated by several cases of students who prefer individual learning and take SGD merely to fulfill attendance requirement. If the students have good wellbeing, they will take the SGD process optimally. The subject of this research was 100 students of Faculty of Medicine of Udayana University. This survey research used psychological test assessment, Psychological well-being scale, and Social Intelligence scale to gain data analyzed quantitatively. The results showed that all aspects of traits together with aspects ‘need for rules and supervision’ affect social intelligence. Furthermore, social intelligence factor with cognitive factors influence wellbeing of the students in the process of SGD.

    Internationally, family doctors seeking to enhance their skills in evidence-based mental health treatment are attending brief training workshops, despite clear evidence in the literature that short-term, massed formats are not likely to improve skills in this complex area. Reviews of the educational literature suggest that an optimal model of training would incorporate distributed practice techniques; repeated practice over a lengthy time period, small-group interactive learning, mentoring relationships, skills-based training and an ongoing discussion of actual patients. This study investigates the potential role of group-based training incorporating multiple aspects of good pedagogy for training doctors in basic competencies in brief cognitive behaviour therapy (BCBT). Six groups of family doctors (n = 32) completed eight 2-hour sessions of BCBT group training over a 6-month period. A baseline control design was utilised with pre- and post-training measures of doctors' BCBT skills, knowledge and engagement in BCBT treatment. Family doctors' knowledge, skills in and actual use of BCBT with patients improved significantly over the course of training compared with the control period. This research demonstrates preliminary support for the efficacy of an empirically derived group training model for family doctors. Brief CBT group-based training could prove to be an effective and viable model for future doctor training.

    2015-10-01

    It is accepted by hospital clinical governance that every clinician's "duty of care" includes hand hygiene, yet globally, health care workers (HCWs) continue to struggle with compliance. Focus group discussions were conducted to explore HCWs' barriers to hand hygiene in Vietnam. Twelve focus group discussions were conducted with HCWs from 6 public hospitals across Hanoi, Vietnam. Discussions included participants' experiences with and perceptions concerning hand hygiene. Tape recordings were transcribed verbatim and then translated into English. Thematic analysis was conducted by 2 investigators. Expressed frustration with high workload, limited access to hand hygiene solutions, and complicated guidelines that are difficult to interpret in overcrowded settings were considered by participants to be bona fide reasons for noncompliance. No participant acknowledged hand hygiene as a duty of care practice for her or his patients. Justification for noncompliance was the observation that visitors did not perform hand hygiene. HCWs did acknowledge a personal duty of care when hand hygiene was perceived to benefit her or his own health, and then neither workload or environmental challenges influenced compliance. Limited resources in Vietnam are amplified by overcrowded conditions and dual bed occupancy. Yet without a systematic systemic duty of care to patient safety, changes to guidelines and resources might not immediately improve compliance. Thus, introducing routine hand hygiene must start with education programs focusing on duty of care. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

    Full Text Available The rapid development of technology influence people‘s life in many aspects including the process of teaching and learning in university, school etc. Some social medias are popular in society, one of them is Facebook. This social networking can be used for any purposes Such as interacting, marketing, publishing, learning etc. The study aims to prove whether Facebook‘s group discussion can be effectively used to improve reading strategies which are normally developed through classroom interaction. It is an action research design involving one group consisting of 37 students randomly sampled out from a population of 198 students. A plan-act-observe-reflect design of the study will be carried out in two cycles. Each cycle involves pretest, treatment and post test. Cycle 1 is undertaken to see if there is a significant difference between the pretest and post test upon treatment. The indicator of success of the treatment is that the post test outscores the pretest. If it does, then Cycle 2 will be conducted to convince the results. If the two cycles show an increase in the mean scores, it can be claimed that the method is effective. In other words, Facebook‘s group discussion can be effectively used to improve reading strategies.

    As part of research investigating the complexities of managing fertility in Australia, public opinions about how Australians manage their fertility were sought from women and men. To identify public opinion about sexual and reproductive health in Australia. To ensure access to a diverse group of people throughout Australia, an online group was advertised and convened on Facebook from October through December 2013. In a closed-group moderated discussion, participants responded to questions about how people in Australia attempt to manage three aspects of fertility: avoiding pregnancy, achieving pregnancy, and difficulties conceiving. Nonidentifiable demographic information was sought; no personal accounts of fertility management were requested. The discussion transcript was analyzed thematically. There were 61 female and 2 male Facebook users aged 18 to 50 years living in Australia participating in the study. Four main themes about fertility management were identified: access, geographical location, knowledge, and cost. Participants reported that young people and people from rural areas face barriers accessing contraception and fertility services. Limited knowledge about sex and reproduction and the cost of fertility services and contraception were also said to impede effective fertility management. Reasons for inequalities in effective fertility management that are amenable to change were identified. Facebook is an effective method for gaining insights into public opinion about sexual and reproductive health.

    In Physics Department Universitas Negeri Semarang, Earth and Space Science subject is included in the curriculum of the third year of physics education students. There are various models of teaching earth and space science subject such as textbook method, lecturer, demonstrations, study tours, problem-solving method, etc. Lectures method is the most commonly used of teaching earth and space science subject. The disadvantage of this method is the lack of two ways interaction between lecturers and students. This research used small group discussion as a teaching method in Earth and Space science. The purpose of this study is to identify the conditions under which an efficient discussion may be initiated and maintained while students are investigating properties of earth and space science subjects. The results of this research show that there is an increase in student’s understanding of earth and space science subject proven through the evaluation results. In addition, during the learning process, student’s activeness also increase.

  18. The impact of service-specific staffing, case scheduling, turnovers, and first-case starts on anesthesia group and operating room productivity: a tutorial using data from an Australian hospital.

    McIntosh, Catherine; Dexter, Franklin; Epstein, Richard H

    2006-12-01

    In this tutorial, we consider the impact of operating room (OR) management on anesthesia group and OR labor productivity and costs. Most of the tutorial focuses on the steps required for each facility to refine its OR allocations using its own data collected during patient care. Data from a hospital in Australia are used throughout to illustrate the methods. OR allocation is a two-stage process. During the initial tactical stage of allocating OR time, OR capacity ("block time") is adjusted. For operational decision-making on a shorter-term basis, the existing workload can be considered fixed. Staffing is matched to that workload based on maximizing the efficiency of use of OR time. Scheduling cases and making decisions on the day of surgery to increase OR efficiency are worthwhile interventions to increase anesthesia group productivity. However, by far, the most important step is the appropriate refinement of OR allocations (i.e., planning service-specific staffing) 2-3 mo before the day of surgery. Reducing surgical and/or turnover times and delays in first-case-of-the-day starts generally provides small reductions in OR labor costs. Results vary widely because they are highly sensitive both to the OR allocations (i.e., staffing) and to the appropriateness of those OR allocations.

    Online social networking is increasingly being used among medical practitioners. However, few studies have evaluated its use in therapeutic endoscopy. Here, we aimed to analyze the shared topics and activities of a group of endoscopic retrograde cholangiopancreatography (ERCP) doctors in a social networking-based endoscopic retrograde cholangiopancreatography discussion group (EDG). Six ERCP trainers working in Xijing Hospital and 48 graduated endoscopists who had finished ERCP training in the same hospital were invited to join in EDG. All group members were informed not to divulge any private information of patients when using EDG. The activities of group members on EDG were retrospectively extracted. The individual data of the graduated endoscopists were collected by a questionnaire. From June 2014 to May 2015, 6924 messages were posted on EDG, half of which were ERCP related. In total, 214 ERCP-related topics were shared, which could be categorized into three types: sharing experience/cases (52.3%), asking questions (38.3%), and sharing literatures/advances (9.3%). Among the 48 graduated endoscopists, 21 had a low case volume of less than 50 per year and 27 had a high volume case volume of 50 or more. High-volume graduated endoscopists posted more ERCP-related messages (P=0.008) and shared more discussion topics (P=0.003) compared with low-volume graduated endoscopists. A survey showed that EDG was useful for graduated endoscopists in ERCP performance and management of post-ERCP complications, etc. A wide range of ERCP-related topics were shared on the social networking-based EDG. The ERCP-related behaviors on EDG were more active in graduated endoscopists with an ERCP case volume of more than 50 per year.

  20. Stakeholders' Perceptions on Shortage of Healthcare Workers in Primary Healthcare in Botswana: Focus Group Discussions.

    Directory of Open Access Journals (Sweden)

    Oathokwa Nkomazana

    Full Text Available An adequate health workforce force is central to universal health coverage and positive public health outcomes. However many African countries have critical shortages of healthcare workers, which are worse in primary healthcare. The aim of this study was to explore the perceptions of healthcare workers, policy makers and the community on the shortage of healthcare workers in Botswana.Fifteen focus group discussions were conducted with three groups of policy makers, six groups of healthcare workers and six groups of community members in rural, urban and remote rural health districts of Botswana. All the participants were 18 years and older. Recruitment was purposive and the framework method was used to inductively analyse the data.There was a perceived shortage of healthcare workers in primary healthcare, which was believed to result from an increased need for health services, inequitable distribution of healthcare workers, migration and too few such workers being trained. Migration was mainly the result of unfavourable personal and family factors, weak and ineffective healthcare and human resources management, low salaries and inadequate incentives for rural and remote area service.Botswana has a perceived shortage of healthcare workers, which is worse in primary healthcare and rural areas, as a result of multiple complex factors. To address the scarcity the country should train adequate numbers of healthcare workers and distribute them equitably to sufficiently resourced healthcare facilities. They should be competently managed and adequately remunerated and the living conditions and rural infrastructure should also be improved.

    The inappropriate translation of scientific information of geohazard (volcanic, landslide and crater lake outgassing) risks to any local population leaves people with incongruent views of the real dangers. Initial workshops organized under the supervision of the VLIR-OI (Flemish Interuniversity Council - Own Initiatives) members have led to the deployment of billboards as requested and drawn up by the locals. The VLIR-OI project has also organized focus group discussions (FGD) with the local stakeholders to find out in various cities, the state of preparedness, the response to emergency situations, the recovery from the emergency and the mitigation. Researchers have preferred open discussion with the local population and its representatives in order to elicit information that otherwise might not be found on a structured questionnaire. FGD provide a meaningful interactive opportunity to collect information and reflection on a wide range of input. The method provides an insight into problems that require a solution through a process of discovering the meaning attributed to certain events or issues. In this research four cardinal points as preparedness, response, recovery and mitigation (Fothergill, 1996) guided the FGD. The population (i.e. local town councils) were constituted by a mix of chiefs, engineers, technicians and civil servants and government officials. In all the three city councils concerned, the engineers in charge complained about the lack of strategic planning, and about the missing of an elaborated strategy for disasters. They are aware of the existence of an organigram in the "Département de l'Action Civile" in Yaounde but never received any "strategic" document. Therefore inappropriate actions might be taken by the municipalities themselves. Fortunately all people interrogated at the FDG always mentioned solidarity in any event.

    2015-01-01

    Background There are limited data to inform the choice between parental presence at clinical bedside rounds (PPCBR) and non-PPCBR in neonatal intensive care units (NICUs). Methods We performed a single-centre, survey-based, crossed-over randomised trial involving parents of all infants who were admitted to NICU and anticipated to stay >11 days. Parents were randomly assigned using a computer-generated stratified block randomisation protocol to start with PPCBR or non-PPCBR and then crossed over to the other arm after a wash-out period. At the conclusion of each arm, parents completed the ‘NICU Parental Stressor Scale’ (a validated tool) and a satisfaction survey. After completion of the trial, we surveyed all healthcare providers who participated at least in one PPCBR rounding episode. We also offered all participating parents and healthcare providers the opportunity to partake in a focus group discussion regarding PPCBR. Results A total of 72 parents were enrolled in this study, with 63 parents (87%) partially or fully completing the trial. Of the parents who completed the trial, 95% agreed that parents should be allowed to attend clinical bedside rounds. A total of 39 healthcare providers’ surveys were returned and 35 (90%) agreed that parents should be allowed to attend rounds. Nine healthcare providers and 8 parents participated in an interview or focus group, augmenting our understanding of the ways in which PPCBR was beneficial. Conclusions Parents and healthcare providers strongly support PPCBR. NICUs should develop policies allowing PPCBR while mitigating the downsides and concerns of parents and healthcare providers such as decreased education opportunity and confidentiality concerns.

  7. Mr. Traore introduces team supervision. Case scenarios for training and group discussion.

    Science.gov (United States)

    1993-01-01

    This supplement to "The Family Planning Manager" presents a case example and five case discussion questions to illustrate the concept of team supervision. In contrast to traditional supervision, where an emphasis is placed on inspection and the uncovering of deficiencies, team supervision uses a facilitative, advocacy-oriented approach. Problem-solving and decision-making responsibilities are assumed by the clinic staff, who identify and analyze problems in group meetings. Thus, the focus shifts from assessing individual performance to evaluating how well they meet clinic objectives as a team. In the team meetings, the visiting supervisor asks the team as a whole to analyze clinic problems and ensures that all staff members are aware of the significance of their contributions. The supervisor also clarifies the division of labor required for implementing solutions and performance standards. Staff are asked if they have concerns they would like communicated to the next organizational level. The supervisory report of the visit can serve as a guide for implementing the recommendations. This approach may require that supervisors and clinic managers receive training in problem solving, motivating staff, team building, and providing constructive feedback.

    Despite a body of evidence on racial/ethnic minority enrollment and retention in research, literature specifically focused on recruiting racially/ethnically diverse older adults for social science studies is limited. There is a need for more rigorous research on methodological issues and the efficacy of recruitment methods. Cultural obstacles to recruitment of racial/ethnic minority older adults include language barriers, lack of cultural sensitivity of target communities on the part of researchers, and culturally inappropriate assessment tools. Guided by the Consolidated Framework for Implementation Research (CFIR), this study critically appraised the recruitment of racial/ethnic minority older adults for focus groups. The initial approach involved using the physical and social infrastructure of the ElderSmile network, a community-based initiative to promote oral and general health and conduct health screenings in places where older adults gather, to recruit racial/ethnic minority adults for a social science component of an interdisciplinary initiative. The process involved planning a recruitment strategy, engaging the individuals involved in its implementation (opinion leaders in senior centers, program staff as implementation leaders, senior community-based colleagues as champions, and motivated center directors as change agents), executing the recruitment plan, and reflecting on the process of implementation. While the recruitment phase of the study was delayed by 6 months to allow for ongoing recruitment and filling of focus group slots, the flexibility of the recruitment plan, the expertise of the research team members, the perseverance of the recruitment staff, and the cultivation of change agents ultimately resulted in meeting the study targets for enrollment in terms of both numbers of focus group discussions (n = 24) and numbers of participants (n = 194). This study adds to the literature in two important ways. First, we leveraged the social and

    College or university is a critical period regarding unhealthy changes in eating behaviours in students. Therefore, the purpose of this study was to explore which factors influence Belgian (European) university students' eating behaviour, using a qualitative research design. Furthermore, we aimed to collect ideas and recommendations in order to facilitate the development of effective and tailored intervention programs aiming to improve healthy eating behaviours in university students. Using a semi-structured question guide, five focus group discussions have been conducted consisting of 14 male and 21 female university students from a variety of study disciplines, with a mean age of 20.6 ± 1.7 yrs. Using Nvivo9, an inductive thematic approach was used for data analysis. After the transition from secondary school to university, when independency increases, students are continuously challenged to make healthful food choices. Students reported to be influenced by individual factors (e.g. taste preferences, self-discipline, time and convenience), their social networks (e.g. (lack of) parental control, friends and peers), physical environment (e.g. availability and accessibility, appeal and prices of food products), and macro environment (e.g. media and advertising). Furthermore, the relationships between determinants and university students' eating behaviour seemed to be moderated by university characteristics, such as residency, student societies, university lifestyle and exams. Recommendations for university administrators and researchers include providing information and advice to enhance healthy food choices and preparation (e.g. via social media), enhancing self-discipline and self-control, developing time management skills, enhancing social support, and modifying the subjective as well as the objective campus food environment by e.g. making healthy foods price-beneficial and by providing vending machines with more healthy products. This is the first European

    1994-01-01

    This study determined if the training provided physics teaching assistants was sufficient to accomplish the objectives of inquiry-based tutorials for an introductory physics course. Qualitative research methods were used: (1) to determine if the Physics by Inquiry method was modeled; (2) to describe the process from the teaching assistant perspective; (3) to determine TA opinions on training methods; (4) to develop a frame of reference to better understand the role of TA's as instructional support staff. The study determined that the teaching assistants verbalized appropriate instructional actions, but were observed to use a predominantly didactic teaching style. TA's held a variety of perceptions and beliefs about inquiry -based learning and how science is learned. They felt comfortable in the role of tutorial instructor. They were satisfied with the training methods provided and had few suggestions to change or improve training for future tutorial instructors. A concurrent theme of teacher action dependent on teacher beliefs was sustained throughout the study. The TA's actions, as tutorial instructors, reflected their educational beliefs, student background and learning experiences. TA's performance as tutorial instructors depended on what they think and believe about learning science. Practical implications exist for training teaching assistants to be tutorial instructors. Some recommendations may be appropriate for TA's required to use instructional methods that they have not experienced as students. Interview prospective teaching assistants to determine educational experience and beliefs. Employ inexperienced teaching assistants whose perspectives match the proposed instructional role and who might be more receptive to modeling. Incorporate training into staff meetings. Provide time for TA's to experience the instructional model with simulation or role play as students and as instructors, accompanied by conference discussion. Use strategies known to enhance

    2016-01-01

    Full Text Available Introduction: The communication between faculty and students is a vital component of optimal facilitation of knowledge and learning. Various factors influence this dynamic. Aim: To assess communication levels between students and teachers in a dental college scenario via focus group discussion. Materials and Methods: The focus group discussion consisted of 10 groups; 5 groups representing the teachers, and 5 groups representing the students. Each group consisted of 6 participants. Hence there were a total of 30 teacher and 30 student participants. Focus group discussion was conducted for each of the groups for 30–45 min duration in the presence of a moderator and a note-taker. Open-ended questions were put across by the moderator to initiate and continue the discussions. The hand-written data taken by the note-taker were transcribed onto a computer on the same day of the discussion. Based on the transcription, domains were created for the student and teacher groups. Results: The issues raised by both the teacher and student groups in this focus group discussion were broadly classified into the following themes: (1 Past versus current scenario, (2 attitudes toward communication and learning, (3 hindrances to effective communication, and (4 potential solutions. Conclusions: Focus group discussion exposed many differences in the perceptions of teachers and students to communication. Each group, however, felt that bridging the teacher-student communication barrier was crucial to improve the teaching-learning experience. Many constructive solutions were provided by both the groups which can help to improve the quality of teaching-learning experience resulting in better quality of education.

    2017-06-01

    As research-based, self-paced electronic learning tools become increasingly available, a critical issue educators encounter is implementing strategies to ensure that all students engage with them as intended. Here, we first discuss the effectiveness of electronic learning tutorials as self-paced learning tools in large enrollment brick and mortar introductory physics courses and then propose a framework for helping students engage effectively with the learning tools. The tutorials were developed via research in physics education and were found to be effective for a diverse group of introductory physics students in one-on-one implementation. Instructors encouraged the use of these tools in a self-paced learning environment by telling students that they would be helpful for solving the assigned homework problems and that the underlying physics principles in the tutorial problems would be similar to those in the in-class quizzes (which we call paired problems). We find that many students in the courses in which these interactive electronic learning tutorials were assigned as a self-study tool performed poorly on the paired problems. In contrast, a majority of student volunteers in one-on-one implementation greatly benefited from the tutorials and performed well on the paired problems. The significantly lower overall performance on paired problems administered as an in-class quiz compared to the performance of student volunteers who used the research-based tutorials in one-on-one implementation suggests that many students enrolled in introductory physics courses did not effectively engage with the tutorials outside of class and may have only used them superficially. The findings suggest that many students in need of out-of-class remediation via self-paced learning tools may have difficulty motivating themselves and may lack the self-regulation and time-management skills to engage effectively with tools specially designed to help them learn at their own pace.

    This research is motivated by the belief in the importance of media in a learning process. Media as an intermediary serves to focus on the attention of learners. Selection of appropriate learning media is very influential on the success of the delivery of information itself both in terms of cognitive, affective and skills. Continental food is a course that studies food that comes from Europe and is very complex. To reduce verbalism and provide more real learning, then the tutorial media is needed. Media tutorials that are audio visual can provide a more concrete learning experience. The purpose of this research is to develop tutorial media in the form of video. The method used is the development method with the stages of analyzing the learning objectives, creating a story board, validating the story board, revising the story board and making video tutorial media. The results show that the making of storyboards should be very thorough, and detailed in accordance with the learning objectives to reduce errors in video capture so as to save time, cost and effort. In video capturing, lighting, shooting angles, and soundproofing make an excellent contribution to the quality of tutorial video produced. In shooting should focus more on tools, materials, and processing. Video tutorials should be interactive and two-way.

    Understanding how to govern emerging distributed research networks is essential to their success. Distributed research networks aggregate patient medical data from many institutions leaving data within the local provider security system. While much is known about patients' views on secondary medical research, little is known about their views on governance of research networks. We conducted six focus groups with patients from three medical centers across the U.S. to understand their perspectives on privacy, consent, and ethical concerns of sharing their data as part of research networks. Participants positively endorsed sharing their health data with these networks believing that doing so could advance healthcare knowledge. However, patients expressed several concerns regarding security and broader ethical issues such as commercialism, public benefit, and social responsibility. We suggest that network governance guidelines move beyond strict technical requirements and address wider socio-ethical concerns by fully including patients in governance processes.

    Full Text Available Postpartum care is an essential part of the experience of childbirth and parenthood. This study explores what women want from postnatal care. Three focus groups, using a semi-structured format, were conducted. A total of 12 mothers, up to six weeks postpartum, participated in the study, which was conducted in two clinics in the Western Cape Metropole. Data was transcribed from taped sessions and analysed using Burnard’s (1991 model of “thematic content analysis” . Seven major categories were identified: Information, Support, Organisation of services, Attitudes of the health team, Contact with other mothers, Practical assistance and Other services. Listening to women is an essential element in the provision of flexible and responsive postnatal care that meets the felt needs of women and families.

    This supplement to "The Family Planning Manager" presents a case example and four related discussion questions to advance administrative staff's ability to prepare a pilot project proposal and budget. In the hypothetical scenario, the Ministry of Health has requested proposals for projects from each region that would increase contraceptive prevalence and reduce discontinuation by a national average of 15%. Outlined, in this document, is a two-year project that would use outreach workers to visit the homes of recent discontinuers and attempt to understand their concerns. The goal was to improve the health of mothers and children in the region by reducing the discontinuation rate among first-time users of contraceptives, while the objective was to reduce the discontinuation rate among first-time users from 27% to 15% by the end of the project. Also developed is a budget for the first year of the project that itemizes expenditures for salaries and wages, benefits, fees, general administration, travel and associated expenses, supplies and equipment, purchased services, and education and training. Finally, the supplement presents a sample summary sheet for the proposed project.

    In May 2012, the Committee of Health and Medicinal Products issued a concept paper on the need to review the points to consider document on multiplicity issues in clinical trials. In preparation for the release of the updated guidance document, Statisticians in the Pharmaceutical Industry held a one-day expert group meeting in January 2013. Topics debated included multiplicity and the drug development process, the usefulness and limitations of newly developed strategies to deal with multiplicity, multiplicity issues arising from interim decisions and multiregional development, and the need for simultaneous confidence intervals (CIs) corresponding to multiple test procedures. A clear message from the meeting was that multiplicity adjustments need to be considered when the intention is to make a formal statement about efficacy or safety based on hypothesis tests. Statisticians have a key role when designing studies to assess what adjustment really means in the context of the research being conducted. More thought during the planning phase needs to be given to multiplicity adjustments for secondary endpoints given these are increasing in importance in differentiating products in the market place. No consensus was reached on the role of simultaneous CIs in the context of superiority trials. It was argued that unadjusted intervals should be employed as the primary purpose of the intervals is estimation, while the purpose of hypothesis testing is to formally establish an effect. The opposing view was that CIs should correspond to the test decision whenever possible. Copyright © 2013 John Wiley & Sons, Ltd.

    Yoshida, Yutaka; Langouche, Guido

    2013-01-01

    First textbook on Moessbauer Spectroscopy covering the complete field. Offers a concise introduction to all aspects of Moessbauer spectroscopy by the leading experts in the field. Tutorials on Moessbauer Spectroscopy. Since the discovery of the Moessbauer Effect many excellent books have been published for researchers and for doctoral and master level students. However, there appears to be no textbook available for final year bachelor students, nor for people working in industry who have received only basic courses in classical mechanics, electromagnetism, quantum mechanics, chemistry and materials science. The challenge of this book is to give an introduction to Moessbauer Spectroscopy for this level. The ultimate goal of this book is to give this audience not only a scientific introduction to the technique, but also to demonstrate in an attractive way the power of Moessbauer Spectroscopy in many fields of science, in order to create interest among the readers in joining the community of Moessbauer spectroscopists. This is particularly important at times where in many Moessbauer laboratories succession is at stake.

    Full Text Available Medienereignisse wie auch die Einführung und Verbreitung neuer Medientechnologien und Formate bringen mannigfaltige Wege des „Eintretens von Medien ins Leben“ mit sich. Im Projekt Globale Mediengenerationen (GMG wurden Medienerinnerungen aus der Kindheit im Kontext von Gruppendiskussionen am Beispiel dreier Generationen aus verschiedenen Ländern aller Kontinente untersucht. Dabei wurden medienbezogene Wissensbestände von drei Alterskohorten globaler Generationen analysiert. Der Artikel diskutiert methodologische Aspekte des Projekts und komplexe und selektive Prozesse des Erinnerns vergangener Ereignisse. Er untersucht Gemeinsamkeiten und Unterschiede des GMG-Ansatzes mit dem dokumentarischen Ansatz von Ralf Bohnsack, die beide in der Wissenssoziologie von Karl Mannheim verwurzelt sind. Darüber hinaus wird Medialität als basale methodologische Kategorie in Erwägung gezogen, nicht nur im Hinblick auf die Klärung begrifflicher Grundlagen, sondern auch als inhärente Dimension von Forschungsprozessen. Media events in general and the introduction and divulgence of new media technologies and formats in particular implicate various (new ways of “media entering life.” In the Global Media Generations (GMG research project, articulation of individuals’ memories of childhood experiences with the media was afforded by context of focus groups of three generations in different countries of six continents. In this project media related knowledge segments of different age cohorts have been analyzed and interpreted. The article deals with methodological questions of the project and complex processes of ‘remembering’ past events. It explores commonalities and differences of the GMG approach with Ralf Bohnsack’s documentary approach, both rooted in the sociology of knowledge of Karl Mannheim. Furthermore, mediality is taken into consideration as a basic methodological category, which means that it is perceived not only as subject matter to

  4. Adding problem-based learning tutorials to a traditional lecture-based curriculum: a pilot study in a dental school.

    2005-09-01

    This article reports on the implementation of a problem-based learning (PBL) tutorial in our advanced program for second year students within an existing curriculum. The program was opened on the last 5 days of the summer vacation and students could volunteer to be part of the group. Students separated themselves into small groups by random sampling. The PBL tutorials were done during the first 3 days for medical problems according to our original scenarios (based on medical cases), and during the last 2 days, students made presentations of their learning outcomes, using information technology (IT) by themselves. Throughout this program, students were expected to engage in self-learning, except for a 1(1/2)-h group session with a tutor. Assessment was done by attendance at a group session and by portfolio analysis. Following the portfolio analysis, students identified the number of learning issues (group A, 26 +/- 7 issues; group B, 20 +/- 3 issues; group C, 21 +/- 7 issues). Research, by questionnaire, revealed that 84% of the students were strongly interested in each scenario and 95% of the students felt familiar with each scenario. The levels of satisfaction with the tutor were different in the three groups. All of the students were comfortable in the discussion room and IT center. These results suggested that PBL tutorials are supported by the scenario, the tutor, and the location of the group session, as well as by self-learning. Moreover, one of the most important factors for a PBL tutorial that the student is ready for the free discussions and has enough time for individual self-learning.

  10. The undergraduate physics tutorial program at CSU Los Angeles assessment of utility and areas of interest

    Science.gov (United States)

    Avetyan, Smbat

    The Physics Education Research (PER) group at the University of Washington have researched traditional teaching methods and found that students in introductory physics are lacking a conceptual understanding of the physics material. The solution they put forth is an interactive tutorial program designed to meet the lack of conceptual understanding. Since the tutorial programs inception at CSU Los Angeles in Fall 2006 no evaluation has been successfully undertaken therefore the effect of the tutorial program in the physics 200 series is deeply obscure to the department. The research has shed light on the tutorial program and brought into context its effectiveness on the overall physics 200 series courses at CSU Los Angeles. The researcher has addressed the following research questions, what overall effect does the tutorial program have on the Physics 200 series curriculum? What is the size and significance of gains attributable to the undergraduate calculus based Physics 200 series tutorial program at CSU Los Angeles? What can we learn from gains about individual weekly lessons from the Physics 200 series tutorial courses? What is the correlation of tutorial gains with student final course grades? Are the gains from the tutorial program different for genders? Is there a difference in gains based on the different students' colleges?

  11. Tutorial on beam current monitoring

    International Nuclear Information System (INIS)

    Webber, Robert C.

    2000-01-01

    This paper is a tutorial level review covering a wide range of aspects related to charged particle beam current measurement. The tutorial begins with a look at the characteristics of the beam as a signal source, the associated electromagnetic fields, the influence of the typical accelerator environment on those fields, and the usual means of modifying and controlling that environment to facilitate beam current measurement. Short descriptions of three quite different types of current monitors are presented and a quantitative review of the classical transformer circuit is given. Recognizing that environmental noise pick-up may present a large source of error in quantitative measurements, signal handling considerations are given considerable attention using real-life examples. An example of a successful transport line beam current monitor implementation is presented and the tutorial concludes with a few comments about signal processing and current monitor calibration issues

    Applied optics course in Zhejiang University is a National Excellent Resource Sharing Course in China, and the online to offline teaching strategies have been implemented and shared with dozens of universities and colleges in China. Discussion is an important activity in teaching. In this paper our main consideration is designing the discussion questions and group works so as to develop the students' critical thinking, cooperative and sharing spirits, and communication abilities in the cosmopolitan era. Typical questions that connect different chapters and help the students to understand the relationship between each sub-system in both field of view and aperture are given for discussion. We inspire the students to complete group works such as ray trace programming by cooperation and then make presentations. All of these create a circumstance for sharing thoughts and developing intelligence and knowledge. A poll shows that the students pay more attention to optical design than before and have made progress in conversation and cooperation.

    Arias, Ana; Scott, Raymond; Peters, Ove A; McClain, Elizabeth; Gluskin, Alan H

    2016-04-01

    The aim of this prospective quantitative study was to compare the effect of different instructional formats on dental students' skills and knowledge acquisition for access cavity preparation. All first-year dental students were invited to participate in this study conducted during the four consecutive two-week endodontic rotation courses at the University of the Pacific Arthur A. Dugoni School of Dentistry in spring semester 2015. Four alphabetically distributed intact groups of students were randomly allocated to two groups (n=70 each) that participated in either small-group discussion or a traditional lecture on access preparation. The first outcome measure was skill acquisition, measured by the quality of access cavities prepared in extracted teeth at the conclusion of the session. Two blinded raters scored direct observations on a continuous scale. Knowledge, the second outcome measure, was scored with a multiple-choice and open-ended question test at the end of each two-week session. Data were obtained for 134 of the 140 students, for a 96% response rate. The results showed that students in the small-group discussion groups scored significantly higher than those in the lecture groups when skill performance was tested (p=8.9 × 10(-7)). However, no significant differences were found in the acquisition of knowledge between the two groups on the written test. Active student participation was significantly related to improved manual skill acquisition, but the format of the session does not seem to have had a direct influence on acquired knowledge.

  2. Who is the competent physics student? A study of students' positions and social interaction in small-group discussions

    Science.gov (United States)

    Due, Karin

    2014-06-01

    This article describes a study which explored the social interaction and the reproduction and challenge of gendered discourses in small group discussions in physics. Data for the study consisted of video recordings of eight upper secondary school groups solving physics problems and 15 audiotaped individual interviews with participating students. The analysis was based on gender theory viewing gender both as a process and a discourse. Specifically discursive psychology analysis was used to examine how students position themselves and their peers within discourses of physics and gender. The results of the study reveal how images of physics and of "skilled physics student" were constructed in the context of the interviews. These discourses were reconstructed in the students' discussions and their social interactions within groups. Traditional gendered positions were reconstructed, for example with boys positioned as more competent in physics than girls. These positions were however also resisted and challenged.

    Creutzig, Christopher

    2004-01-01

    This book explains the basic use of the software package called MuPAD and gives an insight into the power of the system. MuPAD is a so-called com­ puter algebra system, which is developed mainly by Sciface Software and the MuPAD Research Group of the University of Paderborn in Germany. This introduction addresses mathematicians, engineers, computer scientists, natural scientists and, more generally, all those in need of mathematical com­ putations for their education or their profession. Generally speaking, this book addresses anybody who wants to use the power of a modern computer algebra package. There are two ways to use a computer algebra system. On the one hand, you may use the mathematical knowledge it incorporates by calling system functions interactively. For example, you can compute symbolic integrals or generate and invert matrices by calling appropriate functions. They comprise the system's mathematical intelligence and may implement sophisticated al­ gorithms. Chapters 2 through 15 discuss this...

    Full Text Available The purpose of the study is to examine the tutorial practices of in-service teachers to address the underachievement in the science education of K-12 students. Method: In-service teachers in Virginia and North Carolina were given a survey questionnaire to examine how they tutored students who were in need of additional instruction. Results: When these teachers were asked, “How do you describe a typical one-on-one science tutorial session?” the majority of their responses were categorized as teacher-directed. Many of the teachers would provide a science tutorial session for a student after school for 16-30 minutes, one to three times a week. Respondents also indicated they would rely on technology, peer tutoring, scientific inquiry, or themselves for one-on-one science instruction. Over half of the in-service teachers that responded to the questionnaire stated that they would never rely on outside assistance, such as a family member or an after school program to provide tutorial services in science. Additionally, very few reported that they incorporated the ethnicity, culture, or the native language of ELL students into their science tutoring sessions.

  9. The role of individualism and the Five-Factor Model in the prediction of performance in a leaderless group discussion.

    Waldman, David A; Atwater, Leanne E; Davidson, Ronald A

    2004-02-01

    Personality has seen a resurgence in the work performance literature. The Five-Factor Model (FFM) represents a set of personality factors that has received the most attention in recent years. Despite its popularity, the FFM may not be sufficiently comprehensive to account for relevant variation across performance dimensions or tasks. Accordingly, the present study also considers how individualism may predict additional variance in performance beyond the FFM. The study involved 152 undergraduate students who experienced a leaderless group discussion (LGD) exercise. Results showed that while the FFM accounted for variance in students' LGD performance, individualism (independence) accounted for additional, unique variance. Furthermore, analyses of the group compositions revealed curvilinear relationships between the relative amount of extraversion, conscientiousness, and individualism in relation to group-level performance.

  10. Selective traditions in group discussions: teachers' views about good science and the possible obstacles when encountering a new topic

    Science.gov (United States)

    Lundqvist, Eva; Sund, Per

    2016-11-01

    There is an ongoing discussion about what content that should be taught in science education and there are different views among teachers about what represent good science content. However, teachers are not isolated individuals making their own interpretations, but are part of institutionalised systems building on patterns in the selection of teaching goals and content. Earlier research shows that teachers teach in alignment with different selective traditions, which can be understood as well-developed teaching habits. Individual teachers seem to develop their personal habits on the basis of the contextual situations created by earlier generations of teachers. In order to find out which content teachers find representative for science education, we asked nine teachers to take part in group interviews to talk about what they value as "good" science content. The participants were grouped according to their selective traditions expressed in earlier studies. The method was used to dynamically explore, challenge and highlight teachers' views. The starting point for the group discussions is national tests in science. In Sweden, national tests in biology, physics and chemistry were introduced in secondary school science (year 9) in 2009. One overarching aim of these tests is to support the implementation of the science curricula and to include for example knowledge about socio-scientific issues (SSI). The content of the tests can consequently be seen as important for teachers to consider. The findings show that `resistance' to including SSI is not just an issue for individual teachers. As individuals teachers can create many kinds of obstacles, but still be interested in integrating SSI in their science teaching. However, in group discussions the teachers tend to collectively adopt the scientific rational discourse. This discourse is what joins them and creates their common identity as science teachers. In turn, they seek to free scientific knowledge from social knowledge

    2011-09-01

    Chronic nursing shortages have placed increasing pressure on many nursing schools to recruit greater numbers of students with the consequence of larger class sizes. Larger class sizes have the potential to lead to student disengagement. This paper describes a case study that examined the strategies used by a group of nursing lecturers to engage students and to overcome passivity in a Bachelor of Nursing programme. A non-participant observer attended 20 tutorials to observe five academics deliver four tutorials each. Academics were interviewed both individually and as a group following the completion of all tutorial observations. All observations, field notes, interviews and focus groups were coded separately and major themes identified. From this analysis two broad categories emerged: getting students involved; and engagement as a struggle. Academics used a wide variety of techniques to interest and involve students. Additionally, academics desired an equal relationship with students. They believed that both they and the students had some power to influence the dynamics of tutorials and that neither party had ultimate power. The findings of this study serve to re-emphasise past literature which suggests that to engage students, the academics must also engage. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2013-01-15

    Prolonged sexual abstinence after childbirth is a socio-cultural practice with health implications, and is described in several African countries, including Tanzania. This study explored discourses on prolonged postpartum sexual abstinence in relation to family health after childbirth in low-income suburbs of Dar es Salaam, Tanzania. Data for the discourse analysis were collected through focus group discussions with first-time mothers and fathers and their support people in Ilala, Dar es Salaam, Tanzania. In this setting, prolonged sexual abstinence intended at promoting child health was the dominant discourse in the period after childbirth. Sexual relations after childbirth involved the control of sexuality for ensuring family health and avoiding the social implications of non-adherence to sexual abstinence norms. Both abstinence and control were emphasised more with regard to women than to men. Although the traditional discourse on prolonged sexual abstinence for protecting child health was reproduced in Ilala, some modern aspects such as the use of condoms and other contraceptives prevailed in the discussion. Discourses on sexuality after childbirth are instrumental in reproducing gender-power inequalities, with women being subjected to more restrictions and control than men are. Thus, interventions that create openness in discussing sexual relations and health-related matters after childbirth and mitigate gendered norms suppressing women and perpetuating harmful behaviours are needed. The involvement of males in the interventions would benefit men, women, and children through improving the gender relations that promote family health.

    Marušić, Ana; Malički, Mario; von Elm, Erik

    2014-01-01

    Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

    2014-01-01

    Background The importance of long term rehabilitation for people with stroke is increasingly evident, yet it is not known whether such services can be materialised in countries with limited community resources. In this study, we explored the perception of rehabilitation professionals and people with stroke towards long term stroke rehabilitation services and potential approaches to enable provision of these services. Views from providers and users are important in ensuring whatever strategies developed for long term stroke rehabilitations are feasible and acceptable. Methods Focus group discussions were conducted involving 15 rehabilitation professionals and eight long term stroke survivors. All recorded conversations were transcribed verbatim and analysed using the principles of qualitative research. Results Both groups agreed that people with stroke may benefit from more rehabilitation compared to the amount of rehabilitation services presently provided. Views regarding the unavailability of long term rehabilitation services due to multi-factorial barriers were recognised. The groups also highlighted the urgent need for the establishment of community-based stroke rehabilitation centres. Family-assisted home therapy was viewed as a potential approach to continued rehabilitation for long term stroke survivors, given careful planning to overcome several family-related issues. Conclusions Barriers to the provision of long term stroke rehabilitation services are multi-factorial. Establishment of community-based stroke rehabilitation centres and training family members to conduct home-based therapy are two potential strategies to enable the continuation of rehabilitation for long term stroke survivors.

    Diagnostic imaging is under-represented in medical curricula globally. Adaptive tutorials, online intelligent tutoring systems that provide a personalized learning experience, have the potential to bridge this gap. However, there is limited evidence of their effectiveness for learning about diagnostic imaging. We performed a randomized mixed methods crossover trial to determine the impact of adaptive tutorials on perceived engagement and understanding of the appropriate use and interpretation of common diagnostic imaging investigations. Although concurrently engaged in disparate blocks of study, 99 volunteer medical students (from years 1-4 of the 6-year program) were randomly allocated to one of two groups. In the first arm of the trial on chest X-rays, one group received access to an adaptive tutorial, whereas the other received links to an existing peer-reviewed Web resource. These two groups crossed over in the second arm of the trial, which focused on computed tomography scans of the head, chest, and abdomen. At the conclusion of each arm of the trial, both groups completed an examination-style assessment, comprising questions both related and unrelated to the topics covered by the relevant adaptive tutorial. Online questionnaires were used to evaluate student perceptions of both learning resources. In both arms of the trial, the group using adaptive tutorials obtained significantly higher assessment scores than controls. This was because of higher assessment scores by senior students in the adaptive tutorial group when answering questions related to topics covered in those tutorials. Furthermore, students indicated significantly better engagement with adaptive tutorials than the Web resource and rated the tutorials as a significantly more valuable tool for learning. Medical students overwhelmingly accept adaptive tutorials for diagnostic imaging. The tutorials significantly improve the understanding of diagnostic imaging by senior students. Crown Copyright

    The General Medical Council has stipulated that greater importance must be placed on undergraduate students developing their ability to lead and work effectively as part of a team. Wales Universities' Officer Training Corps have attempted to meet this requirement through a third year interactive tutorial which aims to encourage students to recognise their strengths and limitations in the six outcomes of leadership, teamwork, accountability, management, feedback and communication. 16 tutorial groups of 10-15 students were each led by one officer who divided the tutorial group into three teams. The teams worked on complex planning exercises with an intrateam constructive feedback discussion to raise students' awareness of their strengths and limitations as individuals during the task, as perceived by others. The student perception was that all six learning outcomes were achieved by the session. 163 students returned feedback questionnaires and learning outcomes 1-4 were felt to have been addressed effectively or very effectively by 90%, 91%, 90% and 86% respondents, respectively. The fifth and sixth outcomes were less well achieved with only 66% and 64% respondents agreeing that the outcomes were achieved effectively or very effectively. Students commended the instructor's demonstration of leadership and the novel teaching method but improvements could be made in reinforcing why these skills are important.

    Despite their legal rights, individuals with disabilities face numerous obstacles to integration in the workplace which can result in their discharge from the labor force. Currently occupational physicians have few resources to help decide whether to integrate disabled workers in pre-placement, or in cases of return-to-work. A network of 13 discussion groups comprised of the occupational physicians of each regional clinic of a large Health Maintenance Organization (HMO) in Israel was created to deal with disability management dilemmas. A moderator compiles and shares the physicians' opinions and experiences with all network members thus assisting the consulting physician in decision-making. Successful management of three representative cases is described to illustrate real-life implementations of this network. The network enables both the consulting and other physicians to tap a large knowledge base and decision-making experience concerning cases of occupational disability management, contributing to professional development and improved service delivery. © 2018 Wiley Periodicals, Inc.

    In this article, we provide a brief tutorial on the estimation, analysis, and simulation on attitude networks using the programming language R. We first discuss what a network is and subsequently show how one can estimate a regularized network on typical attitude data. For this, we use open-access data on the attitudes toward Barack Obama during the 2012 American presidential election. Second, we show how one can calculate standard network measures such as community structure, centrality, and connectivity on this estimated attitude network. Third, we show how one can simulate from an estimated attitude network to derive predictions from attitude networks. By this, we highlight that network theory provides a framework for both testing and developing formalized hypotheses on attitudes and related core social psychological constructs.

    Globally, students with top academic performance and high intellectual capacity usually opt to study medicine. However, once students get enrolled, their academic performance varies widely. Such variations appear to be determined by various factors, one of them being types of learning strategies adopted by students. The learning strategies utilized by the students with better academic performance are likely to be more effective learning strategies. The objective is to identify effective learning strategies used by medical students. This study was carried out among the MBBS students of Final Professional Part I. Students were categorized into three groups namely: high, average, and low rankers based on overall academic performance in second Professional University examination. First, a questionnaire consisting of closed- and open-ended questions was administered to students, to find their learning strategies. Subsequently, focus group discussion and in-depth interviews were conducted for high- and low-rankers. Discussions were audio-recorded, transcribed, and analyzed. Key statements were highlighted, collated, and categorized into general themes and sub-themes. Evident themes which emerged as effective strategies were hard work in the form of regularity of studies, meticulous preparation of notes, constructive use of time, utilization of e-learning, learning styles and deep learning approach and regular ward visits. Intrinsic motivation, family support, balancing physical activities and studies, guidance by seniors, teachers, dealing with nonacademic issues such as language barriers and stress were also identified as important strategies. Disseminating effective learning strategies in a systematic manner may be helpful to students in achieving better academic outcomes. Furthermore, educationists need to modulate their teaching strategies based on students' feedback.

  8. Survey and online discussion groups to develop a patient-rated outcome measure on acceptability of treatment response in vitiligo

    Science.gov (United States)

    2014-01-01

    Background Vitiligo is a chronic depigmenting skin disorder which affects around 0.5-1% of the world’s population. The outcome measures used most commonly in trials to judge treatment success focus on repigmentation. Patient-reported outcome measures of treatment success are rarely used, although recommendations have been made for their inclusion in vitiligo trials. This study aimed to evaluate the face validity of a new patient-reported outcome measure of treatment response, for use in future trials and clinical practice. Method An online survey to gather initial views on what constitutes treatment success for people with vitiligo or their parents/carers, followed by online discussion groups with patients to reach consensus on what constitutes treatment success for individuals with vitiligo, and how this can be assessed in the context of trials. Participants were recruited from an existing database of vitiligo patients and through posts on the social network sites Facebook and Twitter. Results A total of 202 survey responses were received, of which 37 were excluded and 165 analysed. Three main themes emerged as important in assessing treatment response: a) the match between vitiligo and normal skin (how well it blends in); b) how noticeable the vitiligo is and c) a reduction in the size of the white patches. The majority of respondents said they would consider 80% or more repigmentation to be a worthwhile treatment response after 9 months of treatment. Three online discussion groups involving 12 participants led to consensus that treatment success is best measured by asking patients how noticeable their vitiligo is after treatment. This was judged to be best answered using a 5-point Likert scale, on which a score of 4 or 5 represents treatment success. Conclusions This study represents the first step in developing a patient reported measure of treatment success in vitiligo trials. Further work is now needed to assess its construct validity and responsiveness to

    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.

    A management-by-objective approach was used by the health care administration of the Kupat Holim Sick Fund to improve care of hypertension in 20 family practices in the city of Ashdod in central Israel. The doctor-nurse teams in these clinics met jointly on a regular basis with a physician-instructor, reviewed the results of their care of hypertension and discussed ways of improving it. Over a seven-year period, until 1988, the percentage of the population treated increased from 4.0% to 9.2% and percentage of treated patients who had diastolic pressure of 100 mmHg or more fell from 29.6% to 13.4%. Dropout rate ranged from 2.3% to 3.1% per year over the whole period. In 20 other practices in the Ashdod area in 1988 used for comparison, only 5.9% of the population was treated and the per cent treated was less than Ashdod for all age groups above 30. Dropout rate was higher, averaging 9.8% per year, and the percentage of patients with diastolic pressures of 100 mmHg or more was higher (18.1%). Thus the use of regular discussions with feedback to the health care team was associated with better detection, treatment and follow-up of hypertension.

    The aim of this project is to develop an interactive tutorial designed for medical students training in radiation protection in order to use its definitive version in a collaborative group of medical schools. The contents of the tutorial matchers the outlines proposed by the EC guidelines on education and training in Radiation Protection for Medical exposures (RP118), for medical and dental schools. The tutorial is organised in virtual lectures, following a similar structure than the traditional lectures, slides and explanations. There is a central script for each theme with a forward-return interaction. Additionally, branches with deeper explanations (drawings, images, videos,...) are provided to the user. The tutorial is being developed on a set of power Point presentations, linked between them. The user can choose two ways sto launch each lecture, based either on spoken (audio) or written explanations. We present the initial version of a useful tool for pre-graduate training of general practitioners in Radiation Protection, which is a complementary tool for personally adapted computed-based education. Most of the contents can be easily adapted for other students of health related careers (i. e. nurses, technologists...) The use of multimedia tools has been recommended in the field of radiation protection, but developing these tools is time consuming and needs expertise in both, educative and multimedia resources. This projects takes part of more than a dozen multimedia projects on different radiology related subjects developed in our department. (Author) 6 refs

    Co-morbid anxiety and depression in older adults is associated with worse physical and mental health outcomes and poorer response to psychological and pharmacological treatments in older adults. However, there is a paucity of research focused on testing the efficacy of the co-morbid treatment of anxiety and depression in older adults using psychological interventions. Accordingly, the primary objective of the current study was to test the effects of a group cognitive behavior therapy (CBT) program in treating co-morbid anxiety and depression in a sample of older age adults. A total of 133 community-dwelling participants aged ⩾60 years (mean age = 67.35, s.d. = 5.44, male = 59) with both an anxiety disorder and unipolar mood disorder, as assessed on the Anxiety Disorder Interview Schedule (ADIS), were randomly allocated to an 11-week CBT group or discussion group. Participants with Mini-Mental State Examination scores <26 were excluded. Participants were assessed pre-treatment, post-treatment and at 6 months follow-up on the ADIS, a brief measure of well-being, Geriatric Anxiety Inventory and Geriatric Depression Scale. Both conditions resulted in significant improvements over time on all diagnostic, symptom and wellbeing measures. Significant group × time interaction effects emerged at post-treatment only for diagnostic severity of the primary disorder, mean severity of all anxiety disorders, mood disorders, and all disorders, and recovery rates on primary disorder. Group CBT produced faster and sustained improvements in anxiety and depression on diagnostic severity and recovery rates compared to an active control in older adults.

    Household air pollution is a major cause of ill health, but few solutions have been effective to date. While many quantitative studies have been conducted, few have explored the lived experiences and perceptions of women who do the cooking, and as a result are those most exposed to household air pollution. In this study, we worked with groups of home cooks, and sought to use art as a means of engaging them in discussions of how household air pollution from cooking affects their lives. In the Terai district of southern Nepal, we held four focus groups that included 26 local women from urban and peri-urban areas, as well as six local artists. The women then met approximately weekly over four months, and produced images related to air pollution. Transcripts from the focus groups were reviewed independently by two authors, who initially categorised data deductively to pre-defined nodes, and subsequently inductively reviewed emergent themes. Women identified a number of health effects from air pollution. The main physical effects related to the eye and the respiratory system, and women and young children were seen as most vulnerable. The psychosocial effects of air pollution included reduced food intake by women and lethargy. Suggested solutions included modifications to the cooking process, changing the location of stoves, and increasing ventilation. The main barriers were financial. The lived experiences of women in southern Nepal around the problem of air pollution offers a more nuanced and context-specific understanding of the perceptions and challenges of addressing air pollution, which can be used to inform future interventions.

    College or university is a critical period regarding unhealthy changes in energy related behaviours in students. The first objective of this explorative study was to identify determinants of physical activity and sedentary behaviour in Belgian university students. Secondly, we aimed to collect ideas and recommendations to increase physical activity and decrease sedentary behaviours in university students. Using a semi-structured question guide, seven focus group discussions were conducted consisting of 17 male and 29 female university students from a variety of study disciplines, with a mean age of 20.7 ± 1.6 yrs. Using Nvivo9, an inductive thematic approach was used for data analysis. Students reported that both physical and sedentary activities were influenced by individual factors (e.g. perceived enjoyment, self-discipline, time and convenience), their social networks (e.g. (lack of) parental control, modelling, social support), physical environment (e.g. availability and accessibility, travel time/distance, prices), and macro environment (e.g. media and advertising). Furthermore, the relationships between determinants and university students' physical activity and sedentary behaviour seemed to be moderated by university characteristics, such as residency, university lifestyle, exams and academic pressure. Recommendations for future physical activity interventions include improving information strategies regarding on-campus sports activities, cheaper and/or more flexible sports subscriptions and formulas, including 'sports time' into the curricula, and providing university bicycles around campus. Students also believed that increasing students' physical activity might decrease their sedentary behaviour at the same time. The recommendations and ideas discussed in this study may facilitate the development of effective and tailored (multilevel) intervention programs aiming to increase physical activity and decrease sedentary behaviours in university students.

  15. Building shared understandings in introductory physics tutorials through risk, repair, conflict & comedy

    Science.gov (United States)

    Conlin, Luke D.

    Collaborative inquiry learning environments, such as The Tutorials in Physics Sensemaking, are designed to provide students with opportunities to partake in the authentic disciplinary practices of argumentation and sensemaking. Through these practices, groups of students in tutorial can build shared conceptual understandings of the mechanisms behind physical phenomena. In order to do so, they must also build a shared epistemological understanding of what they are doing together, such that their activity includes collaboratively making sense of mechanisms. Previous work (Conlin, Gupta, Scherr, & Hammer, 2007; Scherr & Hammer, 2009) has demonstrated that tutorial students do not settle upon only one way of understanding their activity together, but instead build multiple shared ways of understanding, or framing (Scherr & Hammer, 2009; Tannen, 1993a), their activity. I build upon this work by substantiating a preliminary finding that one of these shared ways of framing corresponds with increased evidence of the students' collaboratively making sense of physical mechanisms. What previous research has not yet addressed is how the students come to understand their activity as including collaborative sensemaking discussions in the first place, and how that understanding develops over the course of the semester. In this dissertation, I address both of these questions through an in-depth video analysis of three groups' discussions throughout the semester. To build shared understandings through scientific argumentation and collaborative sensemaking, the students need to continually make repairs of each other's understanding, but this comes with the risk of affective damage that can shut down further sensemaking discussions. By analyzing the discourse of the three groups' discussions throughout the semester, I show how each group is able to manage this essential tension as they each build and maintain a safe space to sensemake together. I find that the three groups differ in

    The 6-month exclusive breastfeeding rate in the Northeast region of Thailand has recently significantly decreased in contrast to all other regions in Thailand. The factors that have influenced this decrease remain unknown. Hence, it is suggested that an investigation into factors that could improve or hinder EBF for 6 months in Northeast Thailand may be required to inform the development of relevant interventions to improve this situation. This study aimed to identify perceived facilitators and barriers to providing exclusive breastfeeding for 6 months in Northeast Thailand among breastfeeding mothers. Six focus group discussions were conducted with a total of 30 mothers aged 20 to 40 years who had children aged between 4 and 6 months and were currently breastfeeding or had breastfeeding experience. Participants were recruited through self-selection sampling from Khonkaen hospital (urban), Numphong hospital (peri-urban) and private hospitals (urban) in Khonkaen, Thailand. Thematic analysis was employed to analyse the data. Five main themes, with 10 sub-themes, were identified as either facilitators (+) or barriers (-), or in some cases, as both (+/-). Breastfeeding knowledge, perceptions, maternal circumstances, support, and traditional food were the main identified themes. Mother's breastfeeding knowledge, intention to breastfeed, and social media were perceived as facilitators. Perceptions, employment, and formula milk promotion were perceived as barriers. Family, healthcare, and traditional food were perceived as both facilitators and barriers. The perception that social media was a way to access breastfeeding knowledge and support mothers in Northeast Thailand emerged as a new facilitating factor that had not previously been identified in Thai literature relating to facilitators and barriers to exclusive breastfeeding. Intention to breastfeed, family support, healthcare support and traditional food were mentioned by all groups, whereas mothers from urban

    Ongoing research by the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona Steward Observatory suggests that, although faculty realize that lecture-based instruction is ineffective for many students, they are not aware of what interactive teaching strategies are available, particularly for large enrollment courses. A major emphasis of the AAPT/AAS New Faculty Workshop was to introduce faculty to effective active-learning strategies based on an understanding of how people learn. Faculty were introduced to think-pair-share methods where students work together to explain difficult concepts to each other. Faculty were also introduced to authentic assessment strategies that go beyond using traditional multiple-choice tests. In particular, faculty were introduced to Lecture-Tutorials for Introductory Astronomy. The Lecture-Tutorials are instructional materials intended for use with collaborative student learning groups and are designed specifically to be easily integrated into existing courses centered on conventional lectures and do not require any outside equipment or a drastic course revision for implementation. The materials are based on research into student beliefs and reasoning difficulties and use effective instructional strategies that center on student learning. Each workshop presentation was complimented by a follow-up small group discussion session.

    In 2004 the Faculty of Medicine of Universidad de La Frontera in Chile implemented curricular changes, incorporating small group problem based learning in different carriers. To explore aspects that hamper or facilitate tutorial problem based learning from the perspective of tutors. Six in depth interviews and a focus group with tutors were carried out in 2010 and 2011. Data were analyzed through constant comparisons using the program ATLAS ti, guaranteeing credibility, reliance, validation and transferability. Five hundred and twenty eight (528) significance units were identified and 25 descriptive categories emerged. The categories of tutor motivation, methodological domain, tutor responsibility, tutor critical capacity, disciplinary domain, student participation and tutor-student interaction were emphasized. Three qualitative domains were generated, namely tutor skills, transformation of student roles and institutional commitment. Tutorial teaching is favored by teachers when the institutions train them in the subject, when there is administrative support and an adequate infrastructure and coordination.

    Teaching the anatomy of the canine larynx and hyoid apparatus is challenging because dissection disassembles and/or damages these structures, making it difficult to understand their three-dimensional (3D) anatomy and spatial interrelationships. This study assessed the effectiveness of an interactive, computerized 3D tutorial for teaching the anatomy of the canine larynx and hyoid apparatus using a randomized control design with students enrolled in the first-year professional program at Oregon State University College of Veterinary Medicine. All first-year students from 2 consecutive years were eligible. All students received the traditional methods of didactic teaching and dissection to learn the anatomy of the canine larynx and hyoid apparatus, after which they were divided into two statistically equal groups based on their cumulative anatomy test scores from the prior term. The tutorial group received an interactive, computerized tutorial developed by the investigators containing 3D images of the canine larynx and hyoid apparatus, while the control group received the same 3D images without the computerized tutorial. Both groups received the same post-learning assessment and survey. Sixty-three first-year students participated in the study, 28 in the tutorial group, and 35 in the control group. Post-learning assessment and survey scores were both significantly higher among students in the computerized tutorial group than those in the control group. This study demonstrates that a 3D computerized tutorial is more effective in teaching the anatomy of the canine hyoid apparatus and larynx than 3D images without a tutorial. Students likewise rated their learning experience higher when using the 3D computerized tutorial.

    Full Text Available The research and writing processes are often hidden mysteries to our students. A key point in the online tutorial Search and Write (Søk and Skriv has been to supply our students with tools to handle these processes. Learning cases embedded in the tutorial allow us to demonstrate a variety of working techniques and to better cater for a diverse student population. The tutorial can be used as an independent resource for students and as a teaching aid for both library sessions on information literacy and for faculty-led sessions on academic writing. Our tutorial is available in Norwegian and in English and thereby the tutorial can be used with both local and international students. An online tutorial is aimed at all students and therefore the information literacy content is of a general kind. The pedagogical foundation for the Search and Write tutorial is in contextual learning. Adding context to our general content has been important to us and we decided to develop learning cases for this purpose. In our online tutorial we have developed three sample student blogs, Kuhlthau’s information search process functions as a template in structuring the students’ stories. The blogs are learning cases, developed with the intent of illustrating various aspects of academic writing tasks. The blog stories are idealized and touch upon many of the known stumbling stones for student writers. Contextualising the search and write process like this let us explore the diversity of student assignments and from various fields of study. When our real-life students use Search and Write they may use their own research question as a point of departure. They can read the blog stories and relate these stories to their own experiences. They can use the How to brainstorm-tips provided in Sofie’s blog. Christian’s use of tutors, library staff and his writing group can provide guidance on who to ask for help.

    Full Text Available Each company is surrounded by the micro- and macro-environment affecting also its economic performance. These factors are not only individual accounting entries, but also analytical inputs as the internal company processes, management of costs or short-term financial decisions and specifically in the case of agriculture within the EU also the public subsidy schemes implemented through the EU Common Agricultural Policy. Groups of agricultural producers are created as a response to current market dynamics and the opportunity for each agricultural enterprise regardless the size. In this paper, the basis for agricultural cooperation is provided, traditional economic performance measures are presented and their applicability on the sample of agricultural producers’ groups and wholesale entities is empirically verified. Wholesale entities are analysed by its business activity and performance features to consider whether they are suitable peer group for comparing economic performance of examined agricultural producers’ group. Since the economic performance of agricultural producers’ groups directly affects the economic performance of all participating entities, and vice versa, their economic performance measurement may involve specific constraints. According to the structure and characteristics of agricultural producers’ groups may be inferred that whilst the common performance measurement techniques are applicable on the majority of companies, agricultural producers’ groups represent specific entities and therefore need adjusted performance measurement approach.

The purpose of this research is to join the UNESCO initiative by granting quality education, boosted by technology (Rose, 2013. Specifically, the objective is to analyze the impact of using a tutorial video on academic achievement, based on Gestalt psychology stimulating the sensation and perception cognitive capabilities. Using a 50 student sample was used, which was divided into two groups (experimental and control we test whether students that use a tutorial video based on sensation and perception increase their attention and interest to increase academic achievement. The experimental group was a virtual class with tutorial videos on the use of slopes, explanation of the equation, and a virtual graph generator. Both groups were a survey and an exam. The results show that a high impact on the grades and on the perception of knowledge in the experimental group; the average academic achievement of the experimental group was 9.31, against 2 in the control group. Thus, we conclude that the tutorial video presented stimulates cognitive capabilities and improves academic achievement with a 7.3 impact per additional unit of tutorial video, presented as reinforcement of the class.

    This paper describes the pilot evaluation of an Internet-based intervention, designed to teach counselors and problem gamblers about how electronic gambling machines (EGMs) work. This study evaluated the tutorial using assessment tools, such as rating scales and test of knowledge about EGMs and random chance. The study results are based on a number of samples, including problem gambling counselors ( n  = 25) and problem gamblers ( n  = 26). The interactive tutorial was positively rated by both clients and counselors. In addition, we found a significant improvement in scores on a content test about EGM games for both clients and counselors. An analysis of the specific items suggests that the effects of the tutorial were mainly on those items that were most directly related to the content of the tutorial and did not always generalize to other items. This tutorial is available for use with clients and for education counselors. The data also suggest that the tutorial is equally effective in group settings and in individual settings. These results are promising and illustrate that the tool can be used to teach counselors and clients about game design. Furthermore, research is needed to evaluate its impact on gambling behavior.

    2018-06-01

    Explicit emphasis on teaching science process skills leads to both gains in the skills themselves and, strikingly, deeper understanding of content. Here, we created and tested a series of online, interactive tutorials with the goal of helping undergraduate students develop science process skills. We designed the tutorials in accordance with evidence-based multimedia design principles and student feedback from usability testing. We then tested the efficacy of the tutorials in an introductory undergraduate biology class. On the basis of a multivariate ordinary least-squares regression model, students who received the tutorials are predicted to score 0.82 points higher on a 15-point science process skill assessment than their peers who received traditional textbook instruction on the same topic. This moderate but significant impact indicates that well-designed online tutorials can be more effective than traditional ways of teaching science process skills to undergraduate students. We also found trends that suggest the tutorials are especially effective for nonnative English-speaking students. However, due to a limited sample size, we were unable to confirm that these trends occurred due to more than just variation in the student group sampled.

    People with intellectual disability often have few friends and experience social exclusion. Recognising this gap, supported social groups with the aim of inclusion and interdependence were created by a supported employment provider. Interviews were undertaken with 10 adults with intellectual disability exploring their lived experiences of a supported social group. Data were analysed using descriptive phenomenology. Two themes emerged (i) supported engagement fosters wellbeing, and (ii) developing social belonging and connectedness. Participants not only acknowledged the support that they needed to participate, but also that the social group had changed their lives in many ways. Adults with intellectual disability want to socialise, have friends and be part of their community. For this to be achieved, they recognise the need to seek some form of support. With appropriate and targeted support, adults with intellectual disability can move from social exclusion towards supported inclusion and experience richer lives. © 2016 The Authors Journal of Applied Research in Intellectual Disabilities Published by John Wiley & Sons Ltd.

    Risk activities for acquisition of the human immunodeficiency virus (HIV) remain prevalent among urban adolescents. While interdisciplinary approaches to examine the variables contributing to risk/protective behaviors have been promoted, strategies for such explorations require further formulation. Recently we employed focus group discussions to explore factors placing urban adolescents at risk for engaging in HIV risk behaviors. The focus group format enables substantial interaction on a topic in a limited time period, but does not always provide expression of the full range of behavioral options. In this study we investigated the use of pile-sorts for confirmation of impressions from focus group discussions among 57 urban youths aged 10-14. The pile-sorts revealed some support for most of the views expressed in the group discussions. However, the sorts revealed more variability in views than was expressed in the group discussions. Substantial gender and age-based differences in perceptions were revealed with potentially important intervention implications.

    A medical imaging informatics infrastructure (MIII) platform is an organized method of selecting tools and synthesizing data from HIS/RIS/PACS/ePR systems with the aim of developing an imaging-based diagnosis or treatment system. Evaluation and analysis of these systems can be made more efficient by designing and implementing imaging informatics simulators. This tutorial introduces the MIII platform and provides the definition of treatment/diagnosis systems, while primarily focusing on the development of the related simulators. A medical imaging informatics (MII) simulator in this context is defined as a system integration of many selected imaging and data components from the MIII platform and clinical treatment protocols, which can be used to simulate patient workflow and data flow starting from diagnostic procedures to the completion of treatment. In these processes, DICOM and HL-7 standards, IHE workflow profiles, and Web-based tools are emphasized. From the information collected in the database of a specific simulator, evidence-based medicine can be hypothesized to choose and integrate optimal clinical decision support components. Other relevant, selected clinical resources in addition to data and tools from the HIS/RIS/PACS and ePRs platform may also be tailored to develop the simulator. These resources can include image content indexing, 3D rendering with visualization, data grid and cloud computing, computer-aided diagnosis (CAD) methods, specialized image-assisted surgical, and radiation therapy technologies. Five simulators will be discussed in this tutorial. The PACS-ePR simulator with image distribution is the cradle of the other simulators. It supplies the necessary PACS-based ingredients and data security for the development of four other simulators: the data grid simulator for molecular imaging, CAD-PACS, radiation therapy simulator, and image-assisted surgery simulator.

    2018-01-01

    This article is a how-to guide on Bayesian computation using Gibbs sampling, demonstrated in the context of Latent Class Analysis (LCA). It is written for students in quantitative psychology or related fields who have a working knowledge of Bayes Theorem and conditional probability and have experience in writing computer programs in the statistical language R . The overall goals are to provide an accessible and self-contained tutorial, along with a practical computation tool. We begin with how Bayesian computation is typically described in academic articles. Technical difficulties are addressed by a hypothetical, worked-out example. We show how Bayesian computation can be broken down into a series of simpler calculations, which can then be assembled together to complete a computationally more complex model. The details are described much more explicitly than what is typically available in elementary introductions to Bayesian modeling so that readers are not overwhelmed by the mathematics. Moreover, the provided computer program shows how Bayesian LCA can be implemented with relative ease. The computer program is then applied in a large, real-world data set and explained line-by-line. We outline the general steps in how to extend these considerations to other methodological applications. We conclude with suggestions for further readings.

    The terahertz range possesses significant untapped potential for applications including high-volume wireless communications, noninvasive medical imaging, sensing, and safe security screening. However, due to the unique characteristics and constraints of terahertz waves, the vast majority of these applications are entirely dependent upon the availability of beam control techniques. Thus, the development of advanced terahertz-range beam control techniques yields a range of useful and unparalleled applications. This article provides an overview and tutorial on terahertz beam control. The underlying principles of wavefront engineering include array antenna theory and diffraction optics, which are drawn from the neighboring microwave and optical regimes, respectively. As both principles are applicable across the electromagnetic spectrum, they are reconciled in this overview. This provides a useful foundation for investigations into beam control in the terahertz range, which lies between microwaves and infrared light. Thereafter, noteworthy experimental demonstrations of beam control in the terahertz range are discussed, and these include geometric optics, phased array devices, leaky-wave antennas, reflectarrays, and transmitarrays. These techniques are compared and contrasted for their suitability in applications of terahertz waves.

    Librarians at the Boston University Medical Center constructed two interactive online tutorials, "Introduction to EBM" and "Formulating a Clinical Question (PICO)," for a Family Medicine Clerkship and then quickly repurposed the existing tutorials to support an Evidence-based Dentistry course. Adobe's ColdFusion software was used to populate the tutorials with course-specific content based on the URL used to enter each tutorial, and a MySQL database was used to collect student input. Student responses were viewable immediately by course faculty on a password-protected Web site. The tutorials ensured that all students received the same baseline training and allowed librarians to tailor a subsequent library skills workshop to student tutorial answers. The tutorials were well-received by the medical and dental schools and have been added to mandatory first-year Evidence-based Medicine (EBM) and Evidence-based Dentistry (EBD) courses, meaning that every medical and dental student at BUMC will be expected to complete these tutorials.

    Uneven distribution of the medical workforce is globally recognised, with widespread rural health workforce shortages. There has been substantial research on factors affecting recruitment and retention of rural doctors, but little has been done to establish the motives and conditions that encourage allied health professionals to practice rurally. This study aims to identify aspects of recruitment and retention of rural allied health professionals using qualitative methodology. Six focus groups were conducted across rural NSW and analysed thematically using a grounded theory approach. The thirty allied health professionals participating in the focus groups were purposively sampled to represent a range of geographic locations, allied health professions, gender, age, and public or private work sectors. Five major themes emerged: personal factors; workload and type of work; continuing professional development (CPD); the impact of management; and career progression. 'Pull factors' favouring rural practice included: attraction to rural lifestyle; married or having family in the area; low cost of living; rural origin; personal engagement in the community; advanced work roles; a broad variety of challenging clinical work; and making a difference. 'Push factors' discouraging rural practice included: lack of employment opportunities for spouses; perceived inadequate quality of secondary schools; age related issues (retirement, desire for younger peer social interaction, and intention to travel); limited opportunity for career advancement; unmanageable workloads; and inadequate access to CPD. Having competent clinical managers mitigated the general frustration with health service management related to inappropriate service models and insufficient or inequitably distributed resources. Failure to fill vacant positions was of particular concern and frustration with the lack of CPD access was strongly represented by informants. While personal factors affecting recruitment and

    We wanted to investigate the treatment of nuclear energy in literature and cinema, to focus as much as possible on the civil applications of nuclear energy while at the same time trying not to stifle or suppress anything which contributors may feel relevant. We insisted and still do that the purpose was to have a forum for individual not for corporate views, thus the motto: Leave your logo at the door. The question we are dealing with is more related to emotions than anything else: corporations have no emotions. The Internet and e mails still allow fast and personal exchange. The site of the Uranium Institute hosted The Primary Circuit, the 'Internet pub that feeds your mind'. The idea was to have a discussion site for ideas on nuclear energy, the arts (particularly literature) and public perception. The largest body of nuclear related literature is that now known as Survivalist fiction. The separation between military applications and 'Atoms for Peace' was never a fact in people's mind

    The importance of neural networks has grown dramatically during this decade. While only a few years ago they were primarily of academic interest, now dozens of companies and many universities are investigating the potential use of these systems and products are beginning to appear. The idea of building a machine whose architecture is inspired by that of the brain has roots which go far back in history. Nowadays, technological advances of computers and the availability of custom integrated circuits, permit simulations of hundreds or even thousands of neurons. In conjunction, the growing interest in learning machines, non-linear dynamics and parallel computation spurred renewed attention in artificial neural networks. Many tentative applications have been proposed, including decision systems (associative memories, classifiers, data compressors and optimizers), or parametric models for signal processing purposes (system identification, automatic control, noise canceling, etc.). While they do not always outperform standard methods, neural network approaches are already used in some real world applications for pattern recognition and signal processing tasks. The tutorial is divided into six lectures, that where presented at the Third Graduate Summer Course on Computational Physics (September 3-7, 1990) on Parallel Architectures and Applications, organized by the European Physical Society: (1) Introduction: machine learning and biological computation. (2) Adaptive artificial neurons (perceptron, ADALINE, sigmoid units, etc.): learning rules and implementations. (3) Neural network systems: architectures, learning algorithms. (4) Applications: pattern recognition, signal processing, etc. (5) Elements of learning theory: how to build networks which generalize.

of the GOCE user toolbox have played a major role in paving the way to successful use of the GOCE data for
oceanography. The GUT version 2.2 was released in April 2014 and beside some bug-fixes it adds the capability for the computation of Simple Bouguer Anomaly (Solid-Earth). During this fall a new GUT version 3 has been released. GUTv3 was further developed through a collaborative effort where the scientific communities participate aiming
on an implementation of remaining functionalities facilitating a wider span of research in the fields of Geodesy,
Oceanography and Solid earth studies.
Accordingly, the GUT version 3 has:
 - An attractive and easy to use Graphic User Interface (GUI) for the toolbox,
 - Enhance the toolbox with some further software functionalities such as to facilitate the use of gradients,
anisotropic diffusive filtering and computation of Bouguer and isostatic gravity anomalies.
 - An associated GUT VCM tool for analyzing the GOCE variance covariance matrices.

    We sought to determine the effect of group discussion-based education on the self-management capability of patients with type 2 diabetes in Iran. This randomized control trial was conducted on 90 patients with type 2 diabetes. Participants were allocated randomly into one of two groups; intervention and control. The intervention group received the group discussion-based education while the control group received routine care only. The Lin's self-management questionnaire was completed at baseline and three months post-intervention. Statistical analysis, including the use of independent t -test, identified that in comparison to the control group, significant increases were observed in the scores of self-organization ( t =11.24, p health experts ( t = 7.31, p diet ( t = 5.22, p diabetes.

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

    Full Text Available This edited volume comprises a range of studies that have employed a group discussion technique in combination with a specific strategy for reconstructive social research—the so-called documentary method. The latter is an empirical research strategy based on the meta-theoretical premises of the praxeological sociology of knowledge, as developed by Ralf BOHNSACK. It seeks to access practice in a more appropriate manner, namely by differentiating between various dimensions of knowledge and sociality. It holds that habitual collective orientations, in particular, are best accessed through group discussions. Thus this book does not address the group discussion technique in general, as might be expected from the title. Instead, it presents various contributions from researchers interpreting transcripts of group discussions according to the documentary method. The chapters are grouped into three main sections, representing different frameworks of practice and habitual orientation: childhood, adolescence, and organizational or societal context. A fourth section includes chapters on further, potentially useful ways of employing this particular technique and approach, as well as a chapter on teaching it in a meaningful way. Each chapter is structured in the same way: introduction to the research field and focus; methodological discussion; exemplary interpretation of group discussions; and concluding remarks. Whilst the transcripts referred to by the authors are very helpfully presented in the chapters, there is a lack of methodological reflection on the group discussion technique itself, which, as mentioned above, is only evaluated in regard to the documentary method.

    As course directors, we wished to incorporate small group learning into our Evidence-based Medicine course for students to get feedback on the development of a well constructed, researchable clinical question. Scheduling of these groups was problematic. We sought to evaluate computer-mediated communication as an alternative to face-to-face small groups. Students were randomly assigned to either face-to-face small groups or asynchronous, electronic, small groups. Final examination scores were analyzed with an analysis of variance to determine if there were differences in student performance based on group type. Student survey items were analyzed using Fisher's Exact test to determine if there were differences in student attitudes based on group type. There were no significant differences found in overall student performance. Significant differences in student attitudes were found to exist with respect to: (1) participation in discussions, with face-to-face groups reporting greater participation; (2) putting more thought into comments, with electronic groups reporting more thought put into comments; and (3) difficulty relating to other students in the class, with electronic groups reporting more difficulty. We found electronic discussion groups (computer-mediated communication) to be a viable teaching/learning strategy with no adverse effects on student performance or attitudes.

    Full Text Available Hospital Pelopidas Silveira-IMIP/SES/SUS is a tertiary-unit, specialized in cardiology, neurology, neurosurgery and interventional radiology. It is the only hospital of Brazilian Public-Health-System (SUS with this profile and a 24h-acute-cardio/neurovascular facility. Challenges of Continuing-Education include a guaranteeing appropriate level of basic knowledge, b empowering clinical staff to remain up to date in current knowledge. HPS Continuing-Education Program is based on three branches: a Classroom-Tutorials (CT, b Online-Tutorials at "Pelopidas Digital" Virtual-Teaching-Platform (PD-VTP and c Daily-Practice Evaluation (DPE. This paper presents logistic details of HPS Continuing-Education Program. Training team coordinates tutorial meetings and performs continuous statistical analysis. Evaluation team visit hospital departments daily, observing in practice the incorporation of information provided, and retraining individuals in their work scenarios. Both teams perform curriculum development, meeting planning and creation of digital-training-modules. Tutorial meetings have pre/post-tests, allowing monitoring of attendance, topic significance and short-term retention. Tutorial groups are formed by 6-12 employees sharing similarities in training needs. CT is offered to 4 groups-of-interest: a nurses, b nursing assistants, c administrative staff, porters, drivers, d cleaning, laundry and security staff. Problematization and active strategies have resulted into an attractive, structured educational program customized to produce short-term results. The strategy is of interest to institutions sharing similar challenges.

    2002-12-01

    This study examined the effectiveness of a series of Web-based, multimedia tutorials on methods of human body composition analysis. Tutorials were developed around four body composition topics: hydrodensitometry (underwater weighing), dual-energy X-ray absorptiometry, bioelectrical impedance analysis, and total body electrical conductivity. Thirty-two students enrolled in the course were randomly assigned to learn the material through either the Web-based tutorials only ("Computer"), a traditional lecture format ("Lecture"), or lectures supplemented with Web-based tutorials ("Both"). All students were administered a validated pretest before randomization and an identical posttest at the completion of the course. The reliability of the test was 0.84. The mean score changes from pretest to posttest were not significantly different among the groups (65.4 plus minus 17.31, 78.82 plus minus 21.50, and 76 plus minus 21.22 for the Computer, Both, and Lecture groups, respectively). Additionally, a Likert-type assessment found equally positive attitudes toward all three formats. The results indicate that Web-based tutorials are as effective as the traditional lecture format for teaching these topics.

    Full Text Available Annette Burgess,1 Kim Oates,2 Kerry Goulston,2 Craig Mellis1 1Central Clinical School, Sydney Medical School, The University of Sydney, Sydney, NSW, Australia; 2Sydney Medical School, The University of Sydney, Sydney, NSW, Australia Background: Bedside teaching lies at the heart of medical education. The learning environment afforded to students during clinical tutorials contributes substantially to their knowledge, thinking, and learning. Situated cognition theory posits that the depth and breadth of the students' learning experience is dependent upon the attitude of the clinical teacher, the structure of the tutorial, and the understanding of tutorial and learning objectives. This theory provides a useful framework to conceptualize how students' experience within their clinical tutorials impacts their knowledge, thinking, and learning. Methods: The study was conducted with one cohort (n=301 of students who had completed year 1 of the medical program at Sydney Medical School in 2013. All students were asked to complete a three-part questionnaire regarding their perceptions of their clinical tutor's attributes, the consistency of the tutor, and the best features of the tutorials and need for improvement. Both quantitative and qualitative data were collected and analyzed using descriptive statistics. Results: The response rate to the questionnaire was 88% (265/301. Students perceived that their tutors displayed good communication skills and enthusiasm, encouraged their learning, and were empathetic toward patients. Fifty-two percent of students reported having the same communications tutor for the entire year, and 28% reported having the same physical examination tutor for the entire year. Students would like increased patient contact, greater structure within their tutorials, and greater alignment of teaching with the curriculum. Conclusion: Situated cognition theory provides a valuable lens to view students' experience of learning within the

    Full Text Available The use of short-lived audio-visual tutorials constitutes an educational resource very attractive for young students, widely familiar with this type of format similar to YouTube clips. Considered as "learning pills", these tutorials are intended to strengthen the understanding of complex concepts that because their dynamic nature can’t be represented through texts or diagrams. However, the inclusion of this type of content in eLearning platforms presents accessibility problems for students with visual or hearing disabilities. This paper describes this problem and shows the way in which a teacher could add captions and subtitles to their videos.

    2016-11-01

    One of the most common approaches to develop a Computational Fluid Dynamic (CFD) simulation for a new case study of interest is to search for the most similar, previously developed and validated CFD simulation among other works. A simple search would result into a pool of written/visual tutorials. However, users should spend significant amount of time and effort to find the most correct, compatible and valid tutorial in this pool and further modify it toward their simulation of interest. SFO is an open-source project with the core idea of saving the above-mentioned time and effort. This is done via documenting/sharing scientific and methodological approaches to develop CFD simulations for a wide spectrum of fundamental and industrial case studies in three different CFD solvers; STAR-CCM +, FLUENT and Open FOAM (SFO). All of the steps and required files of these tutorials are accessible and editable under the common roof of Github (a web-based Git repository hosting service). In this presentation we will present the current library of 20 + developed CFD tutorials, discuss the idea and benefit of using them, their educational values and explain how the next generation of open-access and live resource of CFD tutorials can be built further hand-in-hand within our community.

    Full Text Available Background and Objectives: Problems caused by menstruation are common among women. Focus group discussions are a method of data collection in which a small group of participants discuss a specified topic or issue. This study mainly aimed to determine the effects of health education based on focus group discussions on the promotion of health behaviors of female adolescents residing boarding centers of the Welfare Organization (Tehran, Iran during their menstruation periods. Materials and Methods: This quasi-experimental interventional study recruited all eligible 12-19-year-old female residents (n=61 of the boarding centers affiliated to the Welfare Organization, Tehran, Iran. The data collection tool was a questionnaire including demographic information and puberty health behaviors (health behaviors during the menstruation period. The questionnaires were completed through interviews before and one month after training. The educational intervention lasted for three months. Data were analyzed using paired t and Kolmogorov-Smirnov tests in SPSS16. Results: The mean scores of performance increased from 12.11±4.43 before the intervention to 16.50±2.79 after the intervention (P<0.001. Conclusion: Since the educational intervention based on focus group discussions had positive effects on the participants’ puberty health, such discussions are recommended to educate adolescent girls about puberty issues.

    Full Text Available We have investigated the efficacy of on-line, multimedia learning modules (MLMs as preparation for in-class, lecture-based tutorials in electromagnetism in a physics course for natural science majors (biology and marine science. Specifically, we report the results of a multiple-group pre/post-test research design comparing two groups receiving different treatments with respect to activities preceding participation in Tutorials in Introductory Physics. The different pre-tutorial activities were as follows: (1 students were assigned reading from a traditional textbook, followed by a traditional lecture; and (2 students completed on-line MLMs developed by the Physics Education Research Group at the University of Illinois at Urbana Champaign (UIUC, and commercially known as FlipItPhysics. The MLM treatment group earned significantly higher mid-term examination scores and larger gains in content knowledge as measured by the Conceptual Survey of Electricity and Magnetism (CSEM. Student attitudes towards “reformed” instruction in the form of active-engagement tutorials were also improved. Specifically, post-course surveys showed that MLM-group students believed class time was more effective and the instructor was more clear than reported by non-MLM students, even though there was no significant difference between groups with respect to in-class activities and the same instructor taught both groups. MLM activities can be a highly effective tool for some student populations, especially when student preparation and buy-in are important for realizing significant gains.

    People with intellectual and developmental disabilities (IDD) often demonstrate difficulties in social skills. The purpose of this study was to examine the effects of a comprehensive intervention program on the acquisition of social skills among students with mild IDD. Single subject multiple baseline design across situations was used for teaching five school-age children with mild IDD social skills embedded in school-based situations. Results demonstrate that the intervention program that included video modelling and games embedded with group discussions and simulations increased the level and use of adequate social behaviours within the school's natural environment. Results demonstrate the unique attribution of a comprehensive interactive program for acquisition and transfer of participants' social skills such as language pragmatics and social rules within the school environment. Group discussions and simulations were beneficial and enabled both group and personalized instruction through the unique application of the program designed for the study. © 2016 John Wiley & Sons Ltd.

    Preast, Vanessa; Danielson, Jared; Bender, Holly; Bousson, Maury

    2007-09-01

    Computer-aided instruction (CAI) was developed to teach veterinary students how to make blood smears. This instruction was intended to replace the traditional instructional method in order to promote efficient use of faculty resources while maintaining learning outcomes and student satisfaction. The purpose of this study was to evaluate the effect of a computer-aided blood smear tutorial on 1) instructor's teaching time, 2) students' ability to make blood smears, and 3) students' ability to recognize smear quality. Three laboratory sessions for senior veterinary students were taught using traditional methods (control group) and 4 sessions were taught using the CAI tutorial (experimental group). Students in the control group received a short demonstration and lecture by the instructor at the beginning of the laboratory and then practiced making blood smears. Students in the experimental group received their instruction through the self-paced, multimedia tutorial on a laptop computer and then practiced making blood smears. Data was collected from observation, interview, survey questionnaires, and smear evaluation by students and experts using a scoring rubric. Students using the CAI made better smears and were better able to recognize smear quality. The average time the instructor spent in the room was not significantly different between groups, but the quality of the instructor time was improved with the experimental instruction. The tutorial implementation effectively provided students and instructors with a teaching and learning experience superior to the traditional method of instruction. Using CAI is a viable method of teaching students to make blood smears.

  6. Bilingual asynchronous online discussion groups: design and delivery of an eLearning distance study module for nurse academics in a developing country.

    Lewis, Peter A; Mai, Van Anh Thi; Gray, Genevieve

    2012-04-01

    The advent of eLearning has seen online discussion forums widely used in both undergraduate and postgraduate nursing education. This paper reports an Australian university experience of design, delivery and redevelopment of a distance education module developed for Vietnamese nurse academics. The teaching experience of Vietnamese nurse academics is mixed and frequently limited. It was decided that the distance module should attempt to utilise the experience of senior Vietnamese nurse academics - asynchronous online discussion groups were used to facilitate this. Online discussion occurred in both Vietnamese and English and was moderated by an Australian academic working alongside a Vietnamese translator. This paper will discuss the design of an online learning environment for foreign correspondents, the resources and translation required to maximise the success of asynchronous online discussion groups, as well as the rationale of delivering complex content in a foreign language. While specifically addressing the first iteration of the first distance module designed, this paper will also address subsequent changes made for the second iteration of the module and comment on their success. While a translator is clearly a key component of success, the elements of simplicity and clarity combined with supportive online moderation must not be overlooked. Copyright © 2011 Elsevier Ltd.

    1993-07-01

    In 1974 the IAEA established a special Nuclear Safety Standards (NUSS) programme under which 5 Codes and 55 Safety Guides have been produced in the areas of Governmental Organization, Siting, Design, Operation and Quality Assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in a complex manner which ensured the best possible international consensus. This broad consensus is one of the reasons for a relatively general wording of the main principles and is sometimes a cause of problems in their application to the detailed design of nuclear power plants. The requirements, particularly those of the Codes, often need interpretation when applied to specific cases. In many areas national regulations and technical standards are available, but often even these do not answer all questions and only the practice used in applying certain rules fully reflects the outcome of the detailed consideration given to solving individual cases. In order to present further information on the application and interpretation in the NUSS Codes and Safety Guides, the preparation of a series of Safety Practice publications has been initiated. It is hoped that many Member States will be able to benefit from the experience presented in these documents.

    In 1974 the IAEA established a special Nuclear Safety Standards (NUSS) programme under which 5 Codes and 55 Safety Guides have been produced in the areas of Governmental Organization, Siting, Design, Operation and Quality Assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in a complex manner which ensured the best possible international consensus. This broad consensus is one of the reasons for a relatively general wording of the main principles and is sometimes a cause of problems in their application to the detailed design of nuclear power plants. The requirements, particularly those of the Codes, often need interpretation when applied to specific cases. In many areas national regulations and technical standards are available, but often even these do not answer all questions and only the practice used in applying certain rules fully reflects the outcome of the detailed consideration given to solving individual cases.

    Curriculum 2013 is the new national Curriculum in Indonesia that is targeted to be used in all Indonesian schools in 2019. At this time the teacher training continues but the number and locations of teachers very diffuse and time constraints to be an obstacle for the government to be able to conduct training for teachers. This research resulted in the e-tutorial which is designed for mathematics teachers in studying the process of Curriculum implementation. This product will assist the government in accelerating the preparation of teachers in implementation of Curriculum 2013. This e-tutorial contains the dynamics of Curriculum development, learning model, learning assessment, lesson plan, curriculum stages of implementation and government regulation that is relevant to the implementation of Curriculum 2013. The product development started with a needs analysis through discussions with mathematics teachers about their difficulties in the implementation of the Curriculum 2013. This e-tutorial was developed using Application of Adobe Director 11. This paper discusses the results of need analysis, process development and results of product revisions made based on input from teachers during the FGD. From the discussion, it can be concluded that this e-tutorial easily understood by teachers and help them to understand the implementation of Curriculum 2013

    Increased enrolments of Bachelor of Nursing (BN) students who speak English as a second language (ESL) can help create a multilingual and culturally diverse workforce that is better prepared to meet the needs of increasingly diverse health populations. However, although ESL enrolments are increasing, attrition rates for ESL students tend to be higher than those of native speakers of English, partly due to academic failure. At the same time, concerns have been expressed in some quarters about the low levels of English language of entering students. As it is unlikely that language entry levels to university will be raised, sustainable programmes that help ESL students better meet the academic challenges they may face need to be developed. So far, models of ESL support have been mostly an adjunct to their degree, voluntary and not well attended. This paper discusses a model using tutorials integrated into the first year nursing curriculum that were specifically designed for ESL students with low levels of English language proficiency. The paper also examines students' perceptions of such tutorials, which they found beneficial to their learning.

    Full Text Available Conducting undergraduate studies in the English language, while only a small minority of students speak English at home, poses many problems to learning in the South African context. This article explores how restrictive language policies may influence proper learning and impact negatively on the self-understanding of students. It also explores how multilingualism could help to reduce the continued reliance on English, without doing away with English in its entirety. This is especially relevant in light of English and other colonial languages still being perceived as “languages of power” (Stroud & Kerfoot, 2013, p. 403. Therefore, attention is given to the link between language and power, especially in light of languages often being used to implement, display and preserve power. Language use in the classroom, especially with regard to codeswitching (also called translanguaging, is discussed. Finally, it explores the success that was achieved during multilingual tutorial sessions. In the tutorials, students were encouraged to explore the course work in their native languages, thereby internalising it and getting a better understanding thereof.

  12. Guidelines for Effective TAP (Translation for Academic Purposes Tutorial Courses

    Full Text Available An increasing need is felt by the university students, especially at Master’s or PhD level, to get a satisfactory command of English so as to manage great amounts of technical materials and articles published internationally. Public and private language institutions, however, have not responded to this need properly specially in non-English speaking countries including Iran. Therefore, the only way left for the students is to demand tutorial sessions which are rare, and if existing, of diverse questionable quality. There seems to be a dearth of base-line or criteria released in any form to define and guide the tutors’ approach and techniques which can be in accordance with university students’ needs and purposes. Aiming to fill this gap, the present paper attempts to be a pioneering research in the realm of TAP (Translation for Academic Purposes tutorial courses and intends to provide guidelines on text selection, role allocation, timing, rate, assignments and other relevant issues in this area. The guidelines are provided based on a post facto case study carried out by one of the authors which created the motive for this research and may further clarify the significance of the issues discussed. The recommended guidelines consist of 5 basic elements and 3 principles. It was discovered, and is expected for others as well, that following these guidelines helps to manage a TAP course in the best and most fruitful way with the least time wasted and with satisfactory result.

    2006-09-01

    Full Text Available The authors focus their analysis in this article on online focus groups (FGs, in an attempt to describe how the setting shapes the conversational features of the discussion and influences data construction. Starting from a review of current dominant viewpoints, they compare face-to-face discussion groups with different formats of online FGs about AIDS, from a discourse analysis perspective. They conducted 2 face-to-face FGs, 2 chats, 2 forums, and 2 forums+plus+chat involving 64 participants aged 18 to 25 and living in Italy. Their findings seem not only to confirm the hypothesis of a general difference between a face-to-face discussion setting and an Internet-mediated one but also reveal differences among the forms of online FG, in terms of both the thematic articulation of discourse and the conversational and relational characteristics of group exchange, suggesting that exchanges on HIV/AIDS are characterized by the setting. This characterization seems to be important for situating the choice of tool, according to research objectives, and for better defining the technical aspects of the research project.

    2016-10-01

    Simulation models are widely used in risk analysis to study the effects of uncertainties on outcomes of interest in complex problems. Often, these models are computationally complex and time consuming to run. This latter point may be at odds with time-sensitive evaluations or may limit the number of parameters that are considered. In this article, we give an introductory tutorial focused on parallelizing simulation code to better leverage modern computing hardware, enabling risk analysts to better utilize simulation-based methods for quantifying uncertainty in practice. This article is aimed primarily at risk analysts who use simulation methods but do not yet utilize parallelization to decrease the computational burden of these models. The discussion is focused on conceptual aspects of embarrassingly parallel computer code and software considerations. Two complementary examples are shown using the languages MATLAB and R. A brief discussion of hardware considerations is located in the Appendix. © 2016 Society for Risk Analysis.

    Lowered costs of genomic sequencing facilitate analyzing large segments of genetic data. Ethical debate has focused on whether and what kind of incidental or secondary findings (SFs) to report, and how to obtain valid informed consent. However, people's support needs after receiving SFs have received less attention. We explored Finnish adults' perspectives on reporting genetic SFs. In this qualitative study which included four focus group discussions (N = 23) we used four vignette letters, each reporting a genetic SF predisposing to a different disease: familial hypercholesterolemia, long QT syndrome, Lynch syndrome, and Li-Fraumeni syndrome. Transcribed focus group discussions were analyzed using inductive thematic analysis. Major themes were immediate shock, dealing with worry and heightened risk, fear of being left alone to deal with SFs, disclosing to family, and identified support needs. Despite their willingness to receive SFs, participants were concerned about being left alone to deal with them. Empathetic expert support and timely access to preventive care were seen as essential to coping with shock and worry, and disclosing SFs to family. Discussion around SFs needs to concern not only which findings to report, but also how healthcare systems need to prepare for providing timely access to preventive care and support for individuals and families.

    Evaluation of the effect of supportive expressive discussion groups on loneliness, hope and quality of life in breast cancer survivors. A randomized control trial including breast cancer patients who had completed chemotherapy and randomly allocated into two groups: intervention (n = 41) and control (n = 40). The intervention consisted of twelve weekly 90-min sessions for groups of six to eight breast cancer survivors. Data were obtained pre-to -post the intervention and at 8-week follow-up. The data were analyzed using a repeated-measures analysis of variance (ANOVA). The findings revealed a significant reduction in loneliness scores (F = 69.85, p hope (F = 20.8, p life from pre- to post-intervention, and then over the 8-week follow-up period in the intervention group, while scores of control participants did not show this pattern during the study. The strongest effects were found for global quality of life (effect size) = 0.59), for future perspectives (effect size = 0.51), emotional functioning (effect size = 0.35) and social functioning (effect size = 0.31). The intervention was effective on loneliness, hope and quality of life in the intervention group. The intervention needs further evaluation in a larger study and with other cancer types.

    This commentary summarizes a small-group discussion that recently occurred at the American Society for Microbiology annual general meeting, ASM Microbe, in Boston, Massachusetts, on 16-20 June 2016, on the topic 'why are so few women choosing to become academics?' Specifically, the discussion focused on asking what the actual and perceived barriers to academic STEM careers women face, and possible solutions to address them which would make women more likely to seek out academic careers. The conclusions reached suggest that, despite improvement in recent years, women and minorities still face complex barriers to STEM academic careers, and further research is needed to determine the best solutions to this problem. © FEMS 2017.

    On behalf of the Drug Metabolism Discussion Group, Regulatory Bioanalysis AstraZeneca (UK) recently organized and hosted an extremely successful Drug Metabolism Discussion Group Short Meeting on 'microsampling--the next big thing'. This attracted over 140 delegates and a strong line up of presenters of respected scientists within the field. This meeting focused on the impact of taking a reduced sample (5-20 µl) from an animal, or later in the clinic, particularly neonates. The agenda covered the spectrum of microsampling, from capillary plasma microsampling, as championed by Ove Jonsson and Kristian Königsson, through to dried blood spots. The day was split up in to three sections, the morning concentrating on the sampling aspects from animals. A highlight of the first section was the 'poster blitz' where four poster presenters gave a quick overview of their work. This introduced the poster session and created a good atmosphere for general debate between the delegates. The mid-session saw the bioanalytical challenges discussed from the discovery to the preclinical stage. To encourage interaction between the presenters and the audience, a panel discussion was used that led to interesting insights into study design from toxicological and bioanalytical viewpoints. The final session was left to clinical aspects of microsampling and a particularly interesting presentation from Hitesh Pandya from the Pediatric Respiratory Medicine Department (University of Leicester, Leicester, UK). An eloquent and hard-hitting presentation put into perspective the importance of advancements in this field that enables sample to be taken in a noninvasive manner. The meeting was well received with excellent feedback from all concerned.

  5. Fall risk awareness and safety precautions taken by older community-dwelling women and men--a qualitative study using focus group discussions.

    Directory of Open Access Journals (Sweden)

    Petra Pohl

    Full Text Available Daily life requires frequent estimations of the risk of falling and the ability to avoid a fall. The objective of this study was to explore older women's and men's understanding of fall risk and their experiences with safety precautions taken to prevent falls.A qualitative study with focus group discussions was conducted. Eighteen community-dwelling people [10 women and 8 men] with and without a history of falls were purposively recruited. Participants were divided into two groups, and each group met four times. A participatory and appreciative action and reflection approach was used to guide the discussions. All discussions were audio recorded and transcribed verbatim. Data were analysed by qualitative content analysis, and categories were determined inductively.Three categories describing the process of becoming aware of fall risks in everyday life were identified: 1] Facing various feelings, 2] Recognizing one's fall risk, and 3] Taking precautions. Each category comprised several subcategories. The comprehensive theme derived from the categories was "Safety precautions through fall risk awareness". Three strategies of ignoring [continuing a risky activity], gaining insight [realizing the danger in a certain situation], and anticipating [thinking ahead and acting in advance] were related to all choices of actions and could fluctuate in the same person in different contexts.The fall risk awareness process might be initiated for various reasons and can involve different feelings and precautions as well as different strategies. This finding highlights that there are many possible channels to reach older people with information about fall risk and fall prevention, including the media and their peers. The findings offer a deeper understanding of older peoples' conceptualizations about fall risk awareness and make an important contribution to the development and implementation of fall prevention programmes.

    Full Text Available Objective – This article discusses a series of actions taken by the Criss Library at the University of Nebraska at Omaha to implement organizational change, using the ClimateQUAL® survey and facilitated discussions with ThinkTank™ group decision software. The library had experienced significant changes over a five-year period, with a renovation of the facility and three reorganizations resulting in a 50% staff turnover. Recognizing the strain that years of construction and personnel changes had placed on the organization, there was a desire to uncover the mood of the employees and reveal the issues behind low morale, uneasiness, and fear.Methods – In November 2009, the library conducted a ClimateQUAL® survey to develop a baseline to assess the effectiveness of any changes. After the results were distributed to library faculty and staff, a series of two-hour facilitated discussions was held to gather opinions and ideas for solutions using thinkLets, a pattern language for reasoning toward a goal. The group support system ThinkTank™ software was loaded onto computers, and employees were able to add their ideas anonymously during the sessions. Finally, 12 employees (29% completed a four-question survey on their perceptions of the facilitated discussions.Results – The facilitated discussions returned 76 sub-themes in 12 categories: staffing and scheduling issues, staff unity/teamwork, communication, goodwill/morale, accountability, decision-making, policy issues, skills and training, leadership, ergonomics/physical work environment, respect, and bullying. An advisory team culled the 76 sub-themes into 40 improvement strategies. Five were implemented immediately, and the remaining 35 were scheduled to be presented to the faculty and staff via an online survey. Participants’ perceptions of the facilitated discussions were mixed. Eighty-three percent of respondents reported that they did not feel safe speaking out about issues, most

    The project was a result of the authority's continued work on the 1998 regulations on protection of human health and the environment in final disposal of spent nuclear fuel and nuclear waste. The idea behind the project, to involve persons from the municipalities participating in SKB's site selection investigation in focus group discussions, was that the questions and points of views that emerged in the discussions could serve as a basis for the authority's work of producing general guidelines associated with the regulations. The finished report would then be handed over to an expert group at the authority which answered or commented on the issues raised, and made a report on this to the participating municipalities Oskarshamn and Oesthammar. The result of discussions in two focus groups in Oskarshamn municipality and two in Oesthammar municipality in October 2002 is presented here, together with a presentation of the project's purpose and organisation. The results are presented in three main sections. The first concentrates on radiation and radioactivity since the task in the discussion groups was to attempt to clarify the issues and problems observed in this area in order to contribute to the authority's work of developing the general guidelines. The second section, on understanding of concepts, measurement, risk and safety, illustrates that the frequently asked and 'simple' knowledge related questions are only the tip of the iceberg where many of the participants have also thought about the more complex contexts and the fundamental problems in the risk and safety analysis, its validity and use. The third section of the report focuses primarily on content and information aspects. It provides a number of ideas about how information on current problems and important issues can be improved, how knowledge can be deepened in the site selection municipalities and how working methods in the process can be developed. The report mainly consists of a presentation of the

    Full Text Available Non-exclusive breast feeding in the early years of life is one of the most important factors in growth and development of infants. Therefore, exclusive breast feeding is recommended during the first six months of life. For determining the effective factors of non-exclusive breast feeding during the first six months of life, we used focus group discussion by participation of 60 mothers who had an infant under 6 months age and enjoyed non-exclusive breast feeding. Mothers divided into eight groups considering their occupation and number of child. All groups reported scanty of mother’s milk, mother’s occupation, mother’s illness, mother’s comfort, wrong beliefs, infant’s illness, doctors and health care providers recommendations, infant’s dependency to feeding bottle and pacifiers as the most frequent factors in using nonexclusive breast feeding. All mothers believed that health care centers, relatives and older members of family, books and pamphlets, mass media, physicians were their effective sources of awareness and promotion of exclusive breast feeding. Considering the presented ideas in all groups, it is realized that mothers during their pregnancy have sparse information about exclusive breast feeding and because of lack of enough essential training, some socio – cultural beliefs affects non-exclusive breast feeding. Mass media and especial training programs should be implemented to promote exclusive breast feeding in Bushehr Port.

    2003-01-01

    In connection to their work on developing a 'general advice document', based on the radiation protection law, the Swedish Radiation Authority (SSI) initiated a process in 2002 that welcomed comments and suggestions from the general public, specifically representatives and interested parties involved in the work related to a Swedish repository for high level nuclear wastes. The authority held a seminar in September, and presented the forthcoming task. The present paper summarises and exemplifies discussions in focus groups in October 2002, when participants from the municipalities of Oskarshamn and Oesthammar met to give their input to the authority's ongoing work. The questions and suggestions emerging from the focus groups are classified into three major areas in this presentation: 1. Issues related specifically to radiation and radioactivity. 2. Issues of comprehension of terminology, measurements, risk, and safety. 3. Issues concerning the information process and the transfer of knowledge. The discussion highlights that issues and comments raised by the public are not constrained to specific knowledge questions, e.g. on radiation or risk, but may relate to legal, strategic and political considerations, as well as the basics of the performed analyses and the related assumptions and evaluations. Ideas for improving public knowledge and for facilitating an exchange of information are outlined below

    To investigate the perceptions, behaviors, and recommendations that parents, school nurses, and teachers have regarding children's use of eyeglasses. Focus groups with parents, school nurses, and teachers were conducted. The study took place in one Southern California school district. There were 39 participants, including 24 parents, seven school nurses, and eight teachers. An experienced moderator guided the focus group discussions. Transcripts were analyzed using grounded theory techniques. Participants perceive visual impairment as a serious problem in the development of children. The lack of eyeglasses may lead to problems such as tiredness, headaches, inability to focus on school work, and decreased reading speed. Participants experienced disappointment, unhappiness, worry, and concern when they realized they needed eyeglasses at a young age. Negative societal perceptions toward eyeglasses, lack of eye doctors in minority communities, parental perceptions that children do not need eyeglasses, and peer bullying of children wearing eyeglasses are key obstacles to children's use of eyeglasses. Participants suggest school and national campaigns featuring respected public figures who wear eyeglasses to promote positive attitudes toward eyeglasses. Parents and teachers who closely follow the academic development of children have observed that visual impairment has negative consequences for the scholastic achievement of children. They recommend interventions to promote the attractiveness of eyeglasses in society. The participants discuss the need for a national preventative message for eye care similar to the message for dental care. The public health message should emphasize the importance of embracing and respecting differences among individuals.

    Full Text Available Peace journalism is fundamental like in any type of reporting. Thus, it facilitates reporters to disseminate information that would help attune to the development of a nation. Base on the available literature, the study discovered that the media have been variously blamed for their role in the exacerbation of different conflicts in complex and heterogeneous countries like Nigeria. The study uses social responsibility theory as a guiding principle. Likewise, Focus Group Discussions (FGD is applied as a methodological approach in data gathering among some selected members of NTA correspondents’ Damaturu, Yobe State. A total number of 10 practicing journalists were randomly selected in NTA, Damaturu. They discussed peace journalism practice and development in the Northeast of Nigeria. Arising from the discussions, the study concludes that all media organisations should imbibe the appropriate way of reporting peace journalism and development in the country, especially in the Northeast of Nigeria where cases of ethnic, religious, political and other types of conflicts have taken the lead.

To distinguish between these two accounts, Miller (1982) derived the well-known race model inequality, which has become a routine test for behavioral data in experiments...... with redundant signals. In this tutorial, we review the basic properties of redundant signals experiments and current statistical procedures used to test the race model inequality during the period between 2011 and 2014. We highlight and discuss several issues concerning study design and the test of the race...... model inequality, such as inappropriate control of Type I error, insufficient statistical power, wrong treatment of omitted responses or anticipations and the interpretation of violations of the race model inequality.

    In the nursing schools, the contrast between what is taught in the classrooms and what is practiced at the health care centers usually creates a great deal of confusion on the part of the students. The objective of this research is to ascertain the opinion of the students and of the professionals at the health care centers where they are doing their training with regard thereto in order to detect their problems and see what differences exist between primary and specialized care. This research was conducted throughout the first half of 2000 employing qualitative methodology, by means of four discussion groups comprised of students, former students, primary care training advisors and nursing professionals at the hospitals where the students of the school in question are doing their nursing training. The initial involvement employed was indirect. The comments of the nursing students and of their training advisors with regard to the practice nursing during the diploma studies reveal dissatisfaction on the part of both of these groups. In all of the groups point out anxiety as the leading factor involved in their teaching as well as learning activities and during professional training. The lack of identification as a group of professionals seems to be related to the lack of recognition on the part of the others, the demand for a degree being granted for their college studies and for the setting up of specialities would contribute to their social recognition and, as a result thereof, to their identification as a professional group. Until a solution is provided to the anxiety which the nursing professionals feel with regard to their professional practice, which they pass on to their students during nursing training, it will not be possible to achieve a higher degree of satisfaction with nursing training experiences either on the part of the training advisors or on the part of the students.

    Purpose - To assess an innovative tutoring program named 'Student-Led Objective Tutorial' (SLOT) among undergraduate medical students. Method - The program was conceptualized by the Pharmacology Unit of Faculty of Medicine and Health Sciences, Asian Institute of Medicine Science & Technology (AIMST), Malaysia and implemented in the middle of 2005. A cohort of 246 medical undergraduate students (spread across 5 consecutive batches) participated. Following a brief explanation on the purpose and nature of SLOT, each batch was divided into small groups and was given a reading assignment on 4 previously delivered lecture topics. Each group was asked to prepare 3-5 multiple choice questions (MCQs) of their own in PowerPoint format to be presented, in turns, to the whole class on the day of SLOT. The proceedings were facilitated by 2 lecturers. Student feedback on the efficacy and benefits were assessed through an anonymous self administered questionnaire. Results - About 76% (188) of the students favored SLOT. The acceptance rate of SLOT was higher among males. There was no significant difference between batches in their opinions on whether to pursue SLOT in future. The most prevalent positive comment was that SLOT enhanced learning skills, and the negative comment being, it consumed more time. Conclusions - SLOT is a novel tutorial method which can offset faculty shortage with advantages like enhanced interest among teachers and learners, uniform reach of content, opportunities for group learning, and involvement of visual aids as teaching-learning (T-L) method. SLOT unraveled the students' potential of peer tutoring both inside as well as outside the classroom. Consumer tutors (students) can be tapped as a resource for SLOT for all subjects and courses in healthcare teaching.

  19. The "magic" of tutorial centres in Hong Kong: An analysis of media marketing and pedagogy in a tutorial centre

    2014-12-01

    Why do more than three-quarters of Hong Kong's senior secondary students flock to tutorial centres like moths to light? What is the "magic" that is driving the popularity of the tutorial centre enterprise? Indeed, looking at the ongoing boom of tutorial centres in Hong Kong (there are almost 1,000 of them), it is difficult not to ask these questions. This paper examines the phenomenon of tutorial centres in Hong Kong and seeks to understand what draws students to these centres. Combining theories of marketing semiotics and emotion studies, the author investigates the pivotal role of media marketing in generating the "magic" of tutorial centres, whose advertising strategy includes, for example, a display of billboard posters featuring stylishly-dressed "celebrity teachers". The author reviews some of the literature available on the subject of tutorial centres. In a case study approach, he then maps out the pedagogy he observed in an English tutorial class, seeking heuristic insights into the kind of teaching students in the study were looking for. He argues that part of the "magical" attraction of what are essentially "cram schools" is their formulaic pedagogy of teaching and reinforcing exam skills. Finally, the paper considers the social implications of the tutorial centre industry in terms of media marketing of education and unequal access to tutorial services.

  20. Manifestations of Differential Cultural Capital in a University Classroom: Views from Classroom Observations and Focus Group Discussions in a South African University

    2014-11-01

    Full Text Available Based predominantly on Pierre Bourdieu’s social and cultural reproduction theory, particularly his notions of cultural capital and symbolic violence, this paper explores how first year post graduate Diploma in Higher Education (PGDHE university students from diverse socio-linguistic backgrounds differ in the levels at which they understand and express themselves in classroom activities. The paper’s thesis is that the diverse nature of South African classrooms presents a number of challenges not only for students but also for educators in terms of the use of English as a medium of instruction or the language for learning and teaching (LOLT. Owing to the fact that the South African Language in Education Policy (LiEP of 1997 empowers both learners and educators in schools to use any of the eleven South African official languages as a LOLT wherever that is reasonably possible, students whose English backgrounds were deficient in enculturating them in the use of English as a learning tool often encounter challenges in expressing their ideas in the classroom, whether in writing or in oral presentations. The discussion is anchored in the data elicited through two data collection methods, lesson observations in a Diploma in Higher Education, Research class composed of students from diverse racial and ethnic backgrounds and through focus group discussion sessions with 40 multi-ethnic Diploma in Higher Education students from the same classroom. The data management and analysis for this study was done thematically, with views emerging from the observations and focus group discussions being clustered into superordinate themes for convenience of the discussion of the findings. The findings of this study were that students from affluent socio-economic backgrounds who enter university with a rich and relevant English linguistic capital, values and attitudes enjoy an enormous advantage compared to their counterparts whose social class and linguistic

    Full Text Available This article reports on a small-scale study into how the Internet might be used for tutorial teaching in archaeology, which was undertaken by the authors as part of their project work for a Teaching Diploma at Oxford University. A workshop was developed to explore how the Internet and image-rich resources online could be exploited within the curriculum, and in turn what changes might need to be made to that curriculum in order to embed a critical, reflective approach to student learning. The practicalities of using the computer in the classroom were also investigated, in terms of available facilities, staff and student training, and the impact of computers on staff-student dynamics. Condron was also involved in a more extensive study of the use of C&IT (communication and information technologies in small-group teaching across a range of subjects (the ASTER project, to which the Oxford case studies have contributed.

    2011-01-01

    A great many computational algorithms developed over the past half-century have been motivated or suggested by biological systems or processes, the most well-known being the artificial neural networks. These algorithms are commonly grouped together under the terms soft or natural computing. A property shared by most natural computing algorithms is that they allow exploration of, or learning from, data. This property has proved extremely valuable in the solution of many diverse problems in science and engineering. The current paper is intended as a tutorial overview of the basic theory of some of the most common methods of natural computing as they are applied in the context of mechanical systems research. The application of some of the main algorithms is illustrated using case studies. The paper also attempts to give some indication as to which of the algorithms emerging now from the machine learning community are likely to be important for mechanical systems research in the future.

    For the past 3 yr, faculty at the University of New Mexico, Department of Biochemistry and Molecular Biology have been using interactive online Problem-Based Learning (PBL) case discussions in our large-enrollment classes. We have developed an illustrative tracking method to monitor student use of problem-solving strategies to provide targeted help to groups and to individual students. This method of assessing performance has a high interrater reliability, and senior students, with training, can serve as reliable graders. We have been able to measure improvements in many students' problem-solving strategies, but, not unexpectedly, there is a population of students who consistently apply the same failing strategy when there is no faculty intervention. This new methodology provides an effective tool to direct faculty to constructively intercede in this area of student development.

  6. Do we have a moral responsibility to compensate for vulnerable groups? A discussion on the right to health for LGBT people.

    Ekmekci, Perihan Elif

    2017-09-01

    Vulnerability is a broad concept widely addressed in recent scholarly literature. Lesbian, gay, bisexual, and transgender (LGBT) people are among the vulnerable populations with significant disadvantages related to health and the social determinants of health. Medical ethics discourse tackles vulnerability from philosophical and political perspectives. LGBT people experience several disadvantages from both perspectives. This article aims to justify the right to health for LGBT people and their particular claims regarding healthcare because they belong to a vulnerable group. Rawls' theory of justice and Norman Daniels' normal functioning approach will be discussed in this context. Despite the fact that the right to health can be justified by Daniels' normal functioning approach, there is still a theoretical gap in justifying the right to health for particular vulnerable populations such as LGBT peopleand discussing society's duty to compensate for these disadvantages. In search of solid theoretical grounds for the justification of the right to health for LGBT people, the present author takes the opportunity to utilize Daniels' flexible definition of normal functioning to show that normal functioning not only varies by age but also by different states of human existence, including sexual orientation and gender identity, and to propose replacing the life span approach with normal states of human existence.

    Full Text Available Household air pollution is a major cause of ill health, but few solutions have been effective to date. While many quantitative studies have been conducted, few have explored the lived experiences and perceptions of women who do the cooking, and as a result are those most exposed to household air pollution. In this study, we worked with groups of home cooks, and sought to use art as a means of engaging them in discussions of how household air pollution from cooking affects their lives. In the Terai district of southern Nepal, we held four focus groups that included 26 local women from urban and peri-urban areas, as well as six local artists. The women then met approximately weekly over four months, and produced images related to air pollution. Transcripts from the focus groups were reviewed independently by two authors, who initially categorised data deductively to pre-defined nodes, and subsequently inductively reviewed emergent themes. Women identified a number of health effects from air pollution. The main physical effects related to the eye and the respiratory system, and women and young children were seen as most vulnerable. The psychosocial effects of air pollution included reduced food intake by women and lethargy. Suggested solutions included modifications to the cooking process, changing the location of stoves, and increasing ventilation. The main barriers were financial. The lived experiences of women in southern Nepal around the problem of air pollution offers a more nuanced and context-specific understanding of the perceptions and challenges of addressing air pollution, which can be used to inform future interventions.

    We have written a software suite designed to facilitate solar data analysis by scientists, students, and the public, anticipating enormous datasets from future instruments. Our “STAR" suite includes an interactive learning section explaining 15 classes of solar events. Users learn software tools that exploit humans’ superior ability (over computers) to identify many events. Annotation tools include time slice generation to quantify loop oscillations, the interpolation of event shapes using natural cubic splines (for loops, sigmoids, and filaments) and closed cubic splines (for coronal holes). Learning these tools in an environment where examples are provided prepares new users to comfortably utilize annotation software with new data. Upon completion of our tutorial, users are presented with media of various solar events and asked to identify and annotate the images, to test their mastery of the system. Goals of the project include public input into the data analysis of very large datasets from future solar satellites, and increased public interest and knowledge about the Sun. In 2010, the Solar Dynamics Observatory (SDO) will be launched into orbit. SDO’s advancements in solar telescope technology will generate a terabyte per day of high-quality data, requiring innovation in data management. While major projects develop automated feature recognition software, so that computers can complete much of the initial event tagging and analysis, still, that software cannot annotate features such as sigmoids, coronal magnetic loops, coronal dimming, etc., due to large amounts of data concentrated in relatively small areas. Previously, solar physicists manually annotated these features, but with the imminent influx of data it is unrealistic to expect specialized researchers to examine every image that computers cannot fully process. A new approach is needed to efficiently process these data. Providing analysis tools and data access to students and the public have proven

    Primary health care (PHC) outreach teams are part of a policy of PHC re-engineering in South Africa. It attempts to move the deployment of community health workers (CHWs) from vertical programmes into an integrated generalised team-based approach to care for defined populations in municipal wards. There has little evaluation of PHC outreach teams. Managers' insights are anecdotal. This is descriptive qualitative study with focus group discussions with health district managers of Johannesburg, the largest city in South Africa. This was conducted in a sequence of three meetings with questions around implementation, human resources, and integrated PHC teamwork. There was a thematic content analysis of validated transcripts using the framework method. There were two major themes: leadership-management challenges and human resource challenges. Whilst there was some positive sentiment, leadership-management challenges loomed large: poor leadership and planning with an under-resourced centralised approach, poor communications both within the service and with community, concerns with its impact on current services and resistance to change, and poor integration, both with other streams of PHC re-engineering and current district programmes. Discussion by managers on human resources was mostly on the plight of CHWs and calls for formalisation of CHWs functioning and training and nurse challenges with inappropriate planning and deployment of the team structure, with brief mention of the extended team. Whilst there is positive sentiment towards intent of the PHC outreach team, programme managers in Johannesburg were critical of management of the programme in their health district. Whilst the objective of PHC reform is people-centred health care, its implementation struggles with a centralising tendency amongst managers in the health service in South Africa. Managers in Johannesburg advocated for decentralisation. The implementation of PHC outreach teams is also limited by

    Full Text Available There is considerable interest in the potential of private sector subsidies to increase availability and affordability of artemisinin-based combination therapies (ACTs for malaria treatment. A cluster randomized trial of such subsidies was conducted in 3 districts in Kenya, comprising provision of subsidized packs of paediatric ACT to retail outlets, training of retail staff, and community awareness activities. The results demonstrated a substantial increase in ACT availability and coverage, though patient counselling and adherence were suboptimal. We conducted a qualitative study in order to understand why these successes and limitations occurred.Eighteen focus group discussions were conducted, 9 with retailers and 9 with caregivers, to document experiences with the intervention. Respondents were positive about intervention components, praising the focused retailer training, affordable pricing, strong promotional activities, dispensing job aids, and consumer friendly packaging, which are likely to have contributed to the positive access and coverage outcomes observed. However, many retailers still did not stock ACT, due to insufficient supplies, lack of capital and staff turnover. Advice to caregivers was poor due to insufficient time, and poor recall of instructions. Adherence by caregivers to dosing guidelines was sub-optimal, because of a wish to save tablets for other episodes, doses being required at night, stopping treatment when the child felt better, and the number and bitter taste of the tablets. Caregivers used a number of strategies to obtain paediatric ACT for older age groups.This study has highlighted that important components of a successful ACT subsidy intervention are regular retailer training, affordable pricing, a reliable supply chain and community mobilization emphasizing patient adherence and when to seek further care.

    Full Text Available Context: Anemia is a major contributor to morbidity and mortality among women of reproductive age. Progress toward reducing the burden of anemia has been little despite efforts through decades. Aims: We conducted this study to unearth the microlevel determinants of anemia among women of reproductive age. Settings and Design: This qualitative study was conducted in Urban Health Centre (UHC, Chetla. Subjects and Methods: A focus group discussion was held among all the eight health staffs, who were involved in reproductive and child health-related service delivery under UHC, Chetla. Analysis Used: A thematic analysis of the transcript was performed. Results: We found that socioeconomic factors like poverty and social neglect, diet and nutrition related factors, lack of personal hygiene, and worm infestation contributed to the burden of anemia, and this was reinforced by factors related to service delivery, such as lack of supply of drugs and supplements, and inadequate training of health workers as well as poor media accountability. Conclusions: Because of easy reversibility and implementation, health service delivery-related issues should be addressed closely through monitoring and evaluation and appropriate and timely action should be taken to improve the effectiveness of the services.

    Full Text Available The authors present a tutorial description of adaptive fractal analysis (AFA. AFA utilizes an adaptive detrending algorithm to extract globally smooth trend signals from the data and then analyzes the scaling of the residuals to the fit as a function of the time scale at which the fit is computed. The authors present applications to synthetic mathematical signals to verify the accuracy of AFA and demonstrate the basic steps of the analysis. The authors then present results from applying AFA to time series from a cognitive psychology experiment on repeated estimation of durations of time to illustrate some of the complexities of real-world data. AFA shows promise in dealing with many types of signals, but like any fractal analysis method there are special challenges and considerations to take into account, such as determining the presence of linear scaling regions.

    2009-10-12

    In this tutorial the main concepts and applications of experimental design in chemistry will be explained. Unfortunately, nowadays experimental design is not as known and applied as it should be, and many papers can be found in which the "optimization" of a procedure is performed one variable at a time. Goal of this paper is to show the real advantages in terms of reduced experimental effort and of increased quality of information that can be obtained if this approach is followed. To do that, three real examples will be shown. Rather than on the mathematical aspects, this paper will focus on the mental attitude required by experimental design. The readers being interested to deepen their knowledge of the mathematical and algorithmical part can find very good books and tutorials in the references [G.E.P. Box, W.G. Hunter, J.S.

    2017-09-01

    Full Text Available Abstract Objective – This article aims to assess student achievement of higher-order information literacy learning outcomes from online tutorials as compared to in-person instruction in science and health science courses. Methods – Information literacy instruction via online tutorials or an in-person one-shot session was implemented in multiple sections of a biology (n=100 and a kinesiology course (n=54. After instruction, students in both instructional environments completed an identical library assignment to measure the achievement of higher-order learning outcomes and an anonymous student survey to measure the student experience of instruction. Results – The data collected from library assignments revealed no statistically significant differences between the two instructional groups in total assignment scores or scores on specific questions related to higher-order learning outcomes. Student survey results indicated the student experience is comparable between instruction groups in terms of clarity of instruction, student confidence in completing the course assignment after library instruction, and comfort in asking a librarian for help after instruction. Conclusions – This study demonstrates that it is possible to replace one-shot information literacy instruction sessions with asynchronous online tutorials with no significant reduction in student learning in undergraduate science and health science courses. Replacing in-person instruction with online tutorials will allow librarians at this university to reach a greater number of students and maintain contact with certain courses that are transitioning to completely online environments. While the creation of online tutorials is initially time-intensive, over time implementing online instruction could free up librarian time to allow for the strategic integration of information literacy instruction into other courses. Additional time savings could be realized by incorporating auto

    Highlights: •The concepts of warping and alignment are introduced. •The most important warping methods are critically reviewed and explained. •Reference selection, evaluation and place of warping in preprocessing are discussed. •Some pitfalls, especially for LC–MS and similar data, are addressed. •Examples are provided, together with programming scripts to rework and extend them. -- Abstract: Warping methods are an important class of methods that can correct for misalignments in (a.o.) chemical measurements. Their use in preprocessing of chromatographic, spectroscopic and spectrometric data has grown rapidly over the last decade. This tutorial review aims to give a critical introduction to the most important warping methods, the place of warping in preprocessing and current views on the related matters of reference selection, optimization, and evaluation. Some pitfalls in warping, notably for liquid chromatography–mass spectrometry (LC–MS) data and similar, will be discussed. Examples will be given of the application of a number of freely available warping methods to a nuclear magnetic resonance (NMR) spectroscopic dataset and a chromatographic dataset. As part of the Supporting Information, we provide a number of programming scripts in Matlab and R, allowing the reader to work the extended examples in detail and to reproduce the figures in this paper.

  12. Tutorial: Determination of thermal boundary resistance by molecular dynamics simulations

    Science.gov (United States)

    Liang, Zhi; Hu, Ming

    2018-05-01

    Due to the high surface-to-volume ratio of nanostructured components in microelectronics and other advanced devices, the thermal resistance at material interfaces can strongly affect the overall thermal behavior in these devices. Therefore, the thermal boundary resistance, R, must be taken into account in the thermal analysis of nanoscale structures and devices. This article is a tutorial on the determination of R and the analysis of interfacial thermal transport via molecular dynamics (MD) simulations. In addition to reviewing the commonly used equilibrium and non-equilibrium MD models for the determination of R, we also discuss several MD simulation methods which can be used to understand interfacial thermal transport behavior. To illustrate how these MD models work for various interfaces, we will show several examples of MD simulation results on thermal transport across solid-solid, solid-liquid, and solid-gas interfaces. The advantages and drawbacks of a few other MD models such as approach-to-equilibrium MD and first-principles MD are also discussed.

    Full Text Available Abstract Background The health workforce in Australia is ageing, particularly in rural areas, where this change will have the most immediate implications for health care delivery and workforce needs. In rural areas, the sustainability of health services will be dependent upon nurses and allied health workers being willing to work beyond middle age, yet the particular challenges for older health workers in rural Australia are not well known. The purpose of this research was to identify aspects of work that have become more difficult for rural health workers as they have become older; and the age-related changes and exacerbating factors that contribute to these difficulties. Findings will support efforts to make workplaces more 'user-friendly' for older health workers. Methods Nurses and allied health workers aged 50 years and over were invited to attend one of six local workshops held in the Hunter New England region of NSW, Australia. This qualitative action research project used a focus group methodology and thematic content analysis to identify and interpret issues arising from workshop discussions. Results Eighty older health workers from a range of disciplines attended the workshops. Tasks and aspects of work that have become more difficult for older health workers in hospital settings, include reading labels and administering medications; hearing patients and colleagues; manual handling; particular movements and postures; shift work; delivery of babies; patient exercises and suturing. In community settings, difficulties relate to vehicle use and home visiting. Significant issues across settings include ongoing education, work with computers and general fatigue. Wider personal challenges include coping with change, balancing work-life commitments, dealing with attachments and meeting goals and expectations. Work and age-related factors that exacerbate difficulties include vision and hearing deficits, increasing tiredness, more complex

    2014-06-01

    This longitudinal study reports the results of a replication of Tutorials in Introductory Physics in high schools of a Latin-American country. The main objective of this study was to examine the suitability of Tutorials for local science education reform. Conceptual learning of simple resistive electric circuits was determined by the application of the single-response multiple-choice test "Determining and Interpreting Resistive Electric Circuits Concepts Test" (DIRECT) to high school classes taught with Tutorials and traditional instruction. The study included state and privately run schools of different socioeconomic profiles, without formal laboratory space and equipment, in classes of mixed-gender and female-only students, taught by novice and experienced instructors. Results systematically show that student learning is significantly higher in the Tutorials classes compared with traditional teaching for all of the studied conditions. The results also show that long-term learning (one year after instruction) in the Tutorials classes is highly satisfactory, very similar to the performance of the samples of college students used to develop the test DIRECT. On the contrary, students following traditional instruction returned one year after instruction to the poor performance (students attending seven universities in Spain and four Latin-American countries. Some replication and adaptation problems and difficulties of this experience are noted, as well as recommendations for successful use of Tutorials in high schools of similar educational systems.

    Tutorials on Mössbauer Spectroscopy Since the discovery of the Mössbauer Effect many excellent books have been published for researchers and for doctoral and master level students.  However, there appears to be no textbook available for final year bachelor students, nor for people working in industry who have received only basic courses in classical mechanics, electromagnetism, quantum mechanics, chemistry and materials science.  The challenge of this book is to give an introduction to Mössbauer Spectroscopy for this level.  The ultimate goal of this book is to give this audience not only a scientific introduction to the technique, but also to demonstrate in an attractive way the power of Mössbauer Spectroscopy in many fields of science, in order to create interest among the readers in joining the community of Mössbauer spectroscopists.  This is particularly important at times where in many Mössbauer laboratories succession is at stake.

    Full Text Available As in other developing nations, important concerns surrounding education in Indonesia involve two issues: quantity versus quality. Quality concerns have now been somewhat addressed by the establishment of the Indonesian Open Learning University (Universitas Terbuka in 1984. The concern for quality, however, has not yet been completely resolved. Learning support, believed to be key for achieving good quality distance education, has been limited. This paper presents the results of two pilot projects that examined tutorials provided via Internet and Fax-Internet technologies. It is a report that also shows that the Universitas Terbuka is faced with both visible and invisible challenges. Visible challenges include limitations in the availability of technology infrastructure and issues of inadequate access, while invisible challenges include the readiness of Indonesian people to adopt and take advantage of new technology for educational purposes. Despite the results of the pilot project, it is suggested that Universitas Terbuka should continue to utilize Internet and Fax-Internet as two of its communication channels with students.

    Gas discharge plasmas formed at atmospheric pressure and near room temperature have recently been shown to be potentially useful for surface and wound sterilization, antisepsis, bleeding cessation, wound healing, and cancer treatment, among other biomedical applications. This tutorial review summarizes the field, stressing the likely role of reactive oxygen and nitrogen species created in these plasmas as the biologically and therapeutically active agents. Reactive species, including radicals and non-radical compounds, are generated naturally within the body and are now understood to be essential for normal biological functions. These species are known to be active agents in existing therapies for wound healing, infection control, and cancer treatment. But they are also observed at elevated levels in persons with many diseases and are associated with aging. The physical and chemical complexity of plasma medical devices and their associated biochemical effects makes the development of safe, effective plasma medical devices and procedures a challenge, but encouragingly rapid progress has been reported around the world in the last several years

    2005-05-01

    Full Text Available The turbo decoding algorithm of a decade ago constituted a milestone in error-correction coding for digital communications, and has inspired extensions to generalized receiver topologies, including turbo equalization, turbo synchronization, and turbo CDMA, among others. Despite an accrued understanding of iterative decoding over the years, the “turbo principle” remains elusive to master analytically, thereby inciting interest from researchers outside the communications domain. In this spirit, we develop a tutorial presentation of iterative decoding for parallel and serial concatenated codes, in terms hopefully accessible to a broader audience. We motivate iterative decoding as a computationally tractable attempt to approach maximum-likelihood decoding, and characterize fixed points in terms of a “consensus” property between constituent decoders. We review how the decoding algorithm for both parallel and serial concatenated codes coincides with an alternating projection algorithm, which allows one to identify conditions under which the algorithm indeed converges to a maximum-likelihood solution, in terms of particular likelihood functions factoring into the product of their marginals. The presentation emphasizes a common framework applicable to both parallel and serial concatenated codes.

    2014-11-01

    As healthcare costs climb around the world, public and private payers alike are demanding evidence of a treatment's value to support approval and reimbursement decisions. Health economics and outcomes research, or HEOR, offers tools to answer questions about a treatment's value, as well as its real-world effects and cost-effectiveness. Given that nutrition interventions have to compete for space in budgets along with biopharmaceutical products and devices, nutrition is now increasingly coming to be evaluated through HEOR. This tutorial introduces the discipline of HEOR and motivates its relevance for nutrition. We first define HEOR and explain its role and relevance in relation to randomized controlled trials. Common HEOR study types--including burden of illness, effectiveness studies, cost-effectiveness analysis, and valuation studies--are presented, with applications to nutrition. Tips for critically reading HEOR studies are provided, along with suggestions on how to use HEOR to improve patient care. Directions for future research are discussed. © 2014 Abbott Nutrition.

The effect of electronic defect disorders in semiconductors appears to control the overall performance of several solid-state ionic devices that include oxide ion conducting solid oxide fuel cells (O-SOFCs), proton conducting solid oxide fuel cells (H-SOFCs), batteries, solar cells, and chemical (gas) sensors. Thus, the present study aims to assess the advances made in typical n- and p-type metal oxide semiconductors with respect to their use in ionic devices. The present paper briefly outlines the key challenges in the development of n- and p-type materials for various applications and also tries to present the state-of-the-art of defect disorders in technologically related semiconductors such as TiO(2), and perovskite-like and fluorite-type structure metal oxides.

    Tutors report difficult incidents and distressing conflicts that adversely affect learning in their problem-based learning (PBL) groups. Faculty development (training) and peer support should help them to manage this. Yet our understanding of these problems and how to deal with them often seems inadequate to help tutors. The aim of this study was to categorise difficult incidents and the interventions that skilled tutors used in response, and to determine the effectiveness of those responses. Thirty experienced and highly rated tutors in our Year 1 and 2 medical curriculum took part in semi-structured interviews to: identify and describe difficult incidents; describe how they responded, and assess the success of each response. Recorded and transcribed data were analysed thematically to develop typologies of difficult incidents and interventions and compare reported success or failure. The 94 reported difficult incidents belonged to the broad categories 'individual student' or 'group dynamics'. Tutors described 142 interventions in response to these difficult incidents, categorised as: (i) tutor intervenes during tutorial; (ii) tutor gives feedback outside tutorial, or (iii) student or group intervenes. Incidents in the 'individual student' category were addressed relatively unsuccessfully (effective 75% of the time) by response (iii). None of the interventions worked well when used in response to problems related to 'group dynamics'. Overall, 59% of the difficult incidents were dealt with successfully. Dysfunctional PBL groups can be highly challenging, even for experienced and skilled tutors. Within-tutorial feedback, the treatment that tutors are most frequently advised to apply, was often not effective. Our study suggests that the collective responsibility of the group, rather than of the tutor, to deal with these difficulties should be emphasised.

  10. What is CCZN-armalcolite? A crystal-chemical discussion and an ad-hoc incursion in the crichtonite-minerals group

    Full Text Available The status of CCZN-armalcolite, commonly still believed to be a variety of armalcolite s.s., is questionable in view of partial evidence suggesting that it would represent a distinct phase, as initially claimed by its discoverers. Because of the rarity of the mineral, combined with its habitual small grain-size, no successful structural investigation could be undertaken so far. Therefore we attempted a chemical overview of existing and original data pertaining to CCZN-armalcolite. With the view of systematizing structure-composition relationships, we analyzed the topology of large cations – bearing close-packed oxides, while extending the nomenclature in use in order to accommodate further topologies. By using relevant chemical plots, a fair compositional match between CCZN-armalcolite and the crichtonite group minerals was demonstrated, as well as a chemical incompatibility with armalcolite. Stoichiometric crichtonite compositions and matching optical properties allowed identification of at least part of “CCZN-armalcolites” with the mineral loveringite of the crichtonite group. A detailed inspection of structure-composition relationships in crichtonites allowed an insight in their trends and range of chemical variation, as well as a comparison between them and a group of “CCZN-armalcolites” slightly differing from known crichtonites. These “CCZN-armalcolites” departing from normal chemical trends in crichtonites either represent an ordered variety of non-stoichiometric crichtonite or a new group of close-packed oxides. Their composition clustering around formula AM16O30 is temptingly consistent with an hypothetical structure intermediate between magnetoplumbites and crichtonites, based on close-packed stacking of layers made up by triangular clusters of octahedra, stuffed with large cations. A model of such a structure, not encountered so far in minerals, is outlined, displaying a hexagonal symmetry P , with a ≈ 7.45Å and c

    Teaching methods that provide an opportunity for individual engagement and focussed feedback are required to create an active learning environment for case-based teaching in large groups. A prospective observational controlled study was conducted to evaluate whether the use of an audience response system (ARS) would promote an active learning environment during case-based discussions in large groups, have an impact on student motivation and improve long-term retention. Group A (N = 83) participated in large group case discussions where student participation was voluntary, while for group B (N = 86) an ARS was used. Data collection methods included student and teacher surveys, student focus group interviews, independent observations and 1-year post-course testing. Results indicated that the use of an ARS provided an active learning environment during case-based discussions in large groups by favouring engagement, observation and critical reflection and by increasing student and teacher motivation. Although final exam results were significantly improved in group B, long-term retention was not significantly different between groups. It was concluded that ARS use significantly improved the learning experience associated with case-based discussions in a large group of undergraduate students.

  13. Tutorial: Asteroseismic Data Analysis with DIAMONDS

    Science.gov (United States)

    Corsaro, Enrico

    Since the advent of the space-based photometric missions such as CoRoT and NASA's Kepler, asteroseismology has acquired a central role in our understanding about stellar physics. The Kepler spacecraft, especially, is still releasing excellent photometric observations that contain a large amount of information not yet investigated. For exploiting the full potential of these data, sophisticated and robust analysis tools are now essential, so that further constraining of stellar structure and evolutionary models can be obtained. In addition, extracting detailed asteroseismic properties for many stars can yield new insights on their correlations to fundamental stellar properties and dynamics. After a brief introduction to the Bayesian notion of probability, I describe the code Diamonds for Bayesian parameter estimation and model comparison by means of the nested sampling Monte Carlo (NSMC) algorithm. NSMC constitutes an efficient and powerful method, in replacement to standard Markov chain Monte Carlo, very suitable for high-dimensional and multimodal problems that are typical of detailed asteroseismic analyses, such as the fitting and mode identification of individual oscillation modes in stars (known as peak-bagging). Diamonds is able to provide robust results for statistical inferences involving tens of individual oscillation modes, while at the same time preserving a considerable computational efficiency for identifying the solution. In the tutorial, I will present the fitting of the stellar background signal and the peak-bagging analysis of the oscillation modes in a red-giant star, providing an example to use Bayesian evidence for assessing the peak significance of the fitted oscillation peaks.

  14. Analysis of information security reliability: A tutorial

    International Nuclear Information System (INIS)

    Kondakci, Suleyman

    2015-01-01

    This article presents a concise reliability analysis of network security abstracted from stochastic modeling, reliability, and queuing theories. Network security analysis is composed of threats, their impacts, and recovery of the failed systems. A unique framework with a collection of the key reliability models is presented here to guide the determination of the system reliability based on the strength of malicious acts and performance of the recovery processes. A unique model, called Attack-obstacle model, is also proposed here for analyzing systems with immunity growth features. Most computer science curricula do not contain courses in reliability modeling applicable to different areas of computer engineering. Hence, the topic of reliability analysis is often too diffuse to most computer engineers and researchers dealing with network security. This work is thus aimed at shedding some light on this issue, which can be useful in identifying models, their assumptions and practical parameters for estimating the reliability of threatened systems and for assessing the performance of recovery facilities. It can also be useful for the classification of processes and states regarding the reliability of information systems. Systems with stochastic behaviors undergoing queue operations and random state transitions can also benefit from the approaches presented here. - Highlights: • A concise survey and tutorial in model-based reliability analysis applicable to information security. • A framework of key modeling approaches for assessing reliability of networked systems. • The framework facilitates quantitative risk assessment tasks guided by stochastic modeling and queuing theory. • Evaluation of approaches and models for modeling threats, failures, impacts, and recovery analysis of information systems

    2017-05-09

    For the 2016 tutorial, NCAR/CGD requested a total budget of $70,000 split equally between DOE and NSF. The funds were used to support student participation (travel, lodging, per diem, etc.). Lectures and practical session support was primarily provided by local participants at no additional cost (see list below). The seventh annual Community Earth System Model (CESM) tutorial (2016) for students and early career scientists was held 8 – 12 August 2016. As has been the case over the last few years, this event was extremely successful and there was greater demand than could be met. There was continued interest in support of the NSF’s EaSM Infrastructure awards, to train these awardees in the application of the CESM. Based on suggestions from previous tutorial participants, the 2016 tutorial experience again provided direct connection to Yellowstone for each individual participant (rather than pairs), and used the NCAR Mesa Library. The 2016 tutorial included lectures on simulating the climate system and practical sessions on running CESM, modifying components, and analyzing data. These were targeted to the graduate student level. In addition, specific talks (“Application” talks) were introduced this year to provide participants with some in-depth knowledge of some specific aspects of CESM.

  17. A tutorial on the principles of harmonic intonation for trombonists

    Science.gov (United States)

    Keener, Michael Kenneth

    A Tutorial on the Principles of Harmonic Intonation for Trombonists includes a manual containing background information, explanations of the principles of harmonic intonation, and printed musical examples for use in learning and practicing the concepts of harmonic intonation. An audio compact disk containing music files corresponding to the printed music completes the set. This tutorial is designed to allow performing musicians and students to practice intonation skills with the pitch-controlled music on the compact disc. The music on the CD was recorded in movable-comma just intonation, replicating performance parameters of wind, string, and vocal ensembles. The compact disc includes sixty tracks of ear-training exercises and interval studies with which to practice intonation perception and adjustment. Tuning notes and examples of equal-tempered intervals and just intervals are included on the CD. The intonation exercises consist of musical major scales, duets, trios, and quartet phrases to be referenced while playing the printed music. The CD tracks allow the performer to play scales in unison (or practice other harmonic intervals) or the missing part of the corresponding duet, trio, or quartet exercise. Instructions in the manual guide the user through a process that can help prepare musicians for more accurate musical ensemble performance. The contextual essay that accompanies the tutorial includes a description of the tutorial, a review of related literature, methodology of construction of the tutorial, evaluations and outcomes, conclusions and recommendations for further research, and a selected bibliography.

    Cervical cancer claims the lives of 275,000 women each year; most of these deaths occur in low-or middle-income countries. In Kenya, cervical cancer is the leading cause of cancer-related mortality among women of reproductive age. Kenya's Ministry of Public Health and Sanitation has developed a comprehensive strategy to prevent cervical cancer, which includes plans for vaccinating preteen girls against human papillomavirus (HPV) by 2015. To identify HPV vaccine communication and mobilization needs, this research sought to understand HPV vaccine-related perceptions and concerns of male and female caregivers and community leaders in four rural communities of western Kenya. We conducted five focus groups with caregivers (n = 56) and 12 key-informant interviews with opinion leaders to explore cervical cancer-related knowledge, attitudes and beliefs, as well as acceptability of HPV vaccination for 9-12 year-old girls. Four researchers independently reviewed the data and developed codes based on questions in interview guides and topics that emerged organically, before comparing and reconciling results through a group consensus process. Cervical cancer was not commonly recognized, though it was understood generally in terms of its symptoms. By association with cancer and genital/reproductive organs, cervical cancer was feared and stigmatized. Overall acceptability of a vaccine that prevents cervical cancer was high, so long as it was endorsed by trusted agencies and communities were sensitized first. Some concerns emerged related to vaccine safety (e.g., impact on fertility), program intent, and health equity. For successful vaccine introduction in Kenya, there is a need for communication and mobilization efforts to raise cervical cancer awareness; prompt demand for vaccination; address health equity concerns and stigma; and minimize potential resistance. Visible endorsement by government leaders and community influencers can provide reassurance of the vaccine's safety

    Symptoms of endometriosis, including pelvic pain, back and nerve pain, and gastrointestinal pain, often begin in adolescence. Yet, research on the experience of these debilitating symptoms among young people is scarce. Of particular concern is the influence of adolescent girls' social context. This study qualitatively examined how, among adolescents, endometriosis and symptoms suggestive of endometriosis is perceived at the family, peer/school and community/society levels. Eight focus groups were conducted; vignettes were used to elicit participants' perceptions of factors that may shape girls' experiences of endometriosis. Data were analysed using constant comparison analysis. An ethnically diverse sample of girls and boys ages 14-18 (n=54) residing in New York City. Fifteen themes emerged and were distilled to eight cross-cutting factors that influence perceptions of endometriosis at different levels of the ecological model: distrust of community healthcare providers, societal stigma of menstruation, peer stigma of endometriosis symptoms, distrust of school healthcare providers, lack of endometriosis knowledge among peers and school personnel, inequitable gender norms, invisibility of symptoms and the stigma of teen sex among parents. Further, these factors may compound symptoms' impact on individual girl's social, educational and emotional well-being. Findings underscore the importance of understanding the social environment of girls experiencing symptoms suggestive of endometriosis and educating and engaging their peers, family and school personnel to create a supportive, informed social climate. Efforts should specifically include stigma reduction campaigns targeted towards female and male adolescents. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available This longitudinal study reports the results of a replication of Tutorials in Introductory Physics in high schools of a Latin-American country. The main objective of this study was to examine the suitability of Tutorials for local science education reform. Conceptual learning of simple resistive electric circuits was determined by the application of the single-response multiple-choice test “Determining and Interpreting Resistive Electric Circuits Concepts Test” (DIRECT to high school classes taught with Tutorials and traditional instruction. The study included state and privately run schools of different socioeconomic profiles, without formal laboratory space and equipment, in classes of mixed-gender and female-only students, taught by novice and experienced instructors. Results systematically show that student learning is significantly higher in the Tutorials classes compared with traditional teaching for all of the studied conditions. The results also show that long-term learning (one year after instruction in the Tutorials classes is highly satisfactory, very similar to the performance of the samples of college students used to develop the test DIRECT. On the contrary, students following traditional instruction returned one year after instruction to the poor performance (<20% shown before instruction, a result compatible with the very low level of conceptual knowledge of basic physics recently determined by a systematic study of first-year students attending seven universities in Spain and four Latin-American countries. Some replication and adaptation problems and difficulties of this experience are noted, as well as recommendations for successful use of Tutorials in high schools of similar educational systems.

La tutoría académica concreta el proceso educativo sustentado en estándares de calidad, características y necesidades de aprendizaje del estudiante; se desenvuelve confrontando actividades pedagógicas y consolida solidaridades. En este contexto, el estudio se realizó con el propósito de realizar la analítica de la solidaridad que surge de la relación tutorial. Método. Desde el ámbito de la hermenéutica, se realizó un estudio en cuatro fases: analítica, comprensiva, reconstructiva, crítica. Se construyó el concepto de solidaridad en la relación tutorial con propuestas de Gadamer, Habermas, Adela Cortina y Edgar Morín. Las categorías de análisis fueron: construcción social del sentido en la relación tutorial, relación tutorial de naturaleza epistémica, compleja, infinita y cambiante; y práctica tutorial generadora de solidaridades. Resultados. La solidaridad como praxis humana orientada al cuidado del otro (Fürsorge promueve el encuentro con el estudiante. La tutoría académica regula la experiencia vital de la dualidad enseñar-aprender; articula la decisión del docente y alumno con la responsabilidad solidaria. El docente concreta un asentimiento aconsejado por la amistad de estar-ahí-con el estudiante, acompañándolo, posibilitando elecciones y decisiones entre posibilidades para una vida sustentable mediante la virtud de la phrónesis. Conclusiones. La solidaridad en la relación tutorial como horizonte de sentido engarza la cosmovisión del binomio docente-estudiante en la relación tutorial. Dado el vínculo social, se ubica en el escenario de la relación tutorial el sentido originario de la amistad y la solidaridad con los siguientes baremos: compasión, saber hacer, confidencialidad, confianza, conciencia de sí mismo y del otro, tacto, escucha atenta y solícita, comprensión del otro.

    Science.gov (United States)

    Soref, Richard

    2018-02-01

    Recent developments in waveguided 2 × 2 and N × M photonic switches are reviewed, including both broadband and narrowband resonant devices for the Si, InP, and AlN platforms. Practical actuation of switches by electro-optical and thermo-optical techniques is discussed. Present datacom-and-computing applications are reviewed, and potential applications are proposed for chip-scale photonic and optoelectronic integrated switching networks. Potential is found in the reconfigurable, programmable "mesh" switches that enable a promising group of applications in new areas beyond those in data centers and cloud servers. Many important matrix switches use gated semiconductor optical amplifiers. The family of broadband, directional-coupler 2 × 2 switches featuring two or three side-coupled waveguides deserves future experimentation, including devices that employ phase-change materials. The newer 2 × 2 resonant switches include standing-wave resonators, different from the micro-ring traveling-wave resonators. The resonant devices comprise nanobeam interferometers, complex-Bragg interferometers, and asymmetric contra-directional couplers. Although the fast, resonant devices offer ultralow switching energy, ˜1 fJ/bit, they have limitations. They require several trade-offs when deployed, but they do have practical application.

    Montgomery, Michele

    2015-08-01

    Although numerical models that researchers use to analyze large astronomy data sets may be easily found on NASA websites, tutorials on how to use these models and understanding the products of the models are lacking. Thus, communication with the public is ineffective. Where the public could easily engage with data and models to determine if their work and lives could be impacted, and if so, to plan accordingly, a lack of good tutorials typically results in the public waiting for a tweet, a post on Facebook, an announcement on a NASA webpage, an alert sent via text message or email, etc. An example is a solar flare or coronal mass ejection event that may impact GPS devices, the precision of which is heavily relied upon by several sectors of the public and military. To allow the public to engage in real time with solar data and NASA developed heliophysics software, we have developed tutorials. In this work, we present our tutorials made for NASA's Living With a Star Program on the such as Integrated Space Weather Analysis (ISWA) layout and the WSA-ENLIL-CONE Model to analyze a CME Evolution that occurred in 2010. We present our results and our analysis of the public's ability to understand the model's predictions of whether the event will impact Earth. By training the public to use the data and to understand model predictions, we turn passive recipients into engaged and self-supporting users of NASA data of space weather events.

  2. Tutorial Video Series: Using Stakeholder Outreach to Increase ...

    Science.gov (United States)

    The limited amount of toxicity data on thousands of chemicals found in consumer products has led to the development of research endeavors such as the U.S. EPA’s Toxicity Forecaster (ToxCast). ToxCast uses high-throughput screening technology to evaluate thousands of chemicals for potential toxicity. At the end of 2013, U.S. EPA released ToxCast chemical data on almost 2,000 chemicals through the interactive Chemical Safety for Sustainability (iCSS) Dashboard. The iCSS Dashboard provides public access to the high-throughput screening data that can be used to inform the evaluation of the safety of chemicals. U.S. EPA recognized early in the development of ToxCast that stakeholder outreach was needed in order to translate the complex scientific information featured in the iCSS Dashboard and data, with the goal of educating the diverse user community through targeted efforts to increase data usage and analysis. Through survey feedback and the request of stakeholders, a series of tutorial videos to demonstrate how to access and use the data has been planned, and the first video of the series has been released to guide data usage. This presentation will describe the video tutorial strategy including an overview of: 1) Stakeholder outreach goals and approach; 2) Planning, production, and dissemination of tutorial videos; 3) Overview of Survey Feedback; 4) Overview of tutorial video usage statistics and usage of the ToxCast data. This stakeholder-outreach approach

  13. Robust variance estimation with dependent effect sizes: practical considerations including a software tutorial in Stata and spss.

    Science.gov (United States)

    Tanner-Smith, Emily E; Tipton, Elizabeth

    2014-03-01

    Methodologists have recently proposed robust variance estimation as one way to handle dependent effect sizes in meta-analysis. Software macros for robust variance estimation in meta-analysis are currently available for Stata (StataCorp LP, College Station, TX, USA) and spss (IBM, Armonk, NY, USA), yet there is little guidance for authors regarding the practical application and implementation of those macros. This paper provides a brief tutorial on the implementation of the Stata and spss macros and discusses practical issues meta-analysts should consider when estimating meta-regression models with robust variance estimates. Two example databases are used in the tutorial to illustrate the use of meta-analysis with robust variance estimates. Copyright © 2013 John Wiley & Sons, Ltd.

  14. Beyond the Letter of the Law: Accessibility, Universal Design, and Human-Centered Design in Video Tutorials

    Directory of Open Access Journals (Sweden)

    Amanda S. Clossen

    2014-05-01

    Full Text Available This article demonstrates how Universal and Human-Centered Design approaches can be applied to the process of library video tutorial creation in order to enhance accessibility. A series of questions that creators should consider in order to focus their design process is discussed. These questions break down various physical and cognitive limitations that users encounter, providing a framework for future video creation that is not dependent on specific software. By approaching accommodations more holistically, videos are created with accessibility in mind from their conception. Working toward the ideal of a video tutorial that is accessible to every user leads to the creation of more clearly worded, effective learning objects that are much more inclusive, making instructional concepts available to users of all abilities.

  16. Tutorial on the Psychophysics and Technology of Virtual Acoustic Displays

    Science.gov (United States)

    Wenzel, Elizabeth M.; Null, Cynthia (Technical Monitor)

    1998-01-01

    Virtual acoustics, also known as 3-D sound and auralization, is the simulation of the complex acoustic field experienced by a listener within an environment. Going beyond the simple intensity panning of normal stereo techniques, the goal is to process sounds so that they appear to come from particular locations in three-dimensional space. Although loudspeaker systems are being developed, most of the recent work focuses on using headphones for playback and is the outgrowth of earlier analog techniques. For example, in binaural recording, the sound of an orchestra playing classical music is recorded through small mics in the two "ear canals" of an anthropomorphic artificial or "dummy" head placed in the audience of a concert hall. When the recorded piece is played back over headphones, the listener passively experiences the illusion of hearing the violins on the left and the cellos on the right, along with all the associated echoes, resonances, and ambience of the original environment. Current techniques use digital signal processing to synthesize the acoustical properties that people use to localize a sound source in space. Thus, they provide the flexibility of a kind of digital dummy head, allowing a more active experience in which a listener can both design and move around or interact with a simulated acoustic environment in real time. Such simulations are being developed for a variety of application areas including architectural acoustics, advanced human-computer interfaces, telepresence and virtual reality, navigation aids for the visually-impaired, and as a test bed for psychoacoustical investigations of complex spatial cues. The tutorial will review the basic psychoacoustical cues that determine human sound localization and the techniques used to measure these cues as Head-Related Transfer Functions (HRTFs) for the purpose of synthesizing virtual acoustic environments. The only conclusive test of the adequacy of such simulations is an operational one in which

    International Nuclear Information System (INIS)

    1993-01-01

    In 1974 the IAEA established a Nuclear Safety Standards (NUSS) programme within which 5 Codes and 55 Safety Guides have been produced in the areas of Governmental Organization, Siting, Design, Operation and Quality Assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in such a manner as to ensure the broadest international consensus. This broad consensus is one of the reasons for the relatively general wording of the main principles and sometimes causes problems when these principles are applied in the design of nuclear power plants. The requirements, particularly those of the Codes, often need interpretation in specific cases. In many areas national regulations and technical standards are available, but often these leave some questions unanswered and their practical application on a case-by-case basis is necessary. To assist in the application and interpretation of the NUSS Safety Standards and Safety Guides, the preparation of a number of Safety Practices publications has been commenced. Ibis publication is intended to assist regulators and also operating organizations. It is a compilation of the reports of the 1991/92 Peer Group discussions which considered regulatory good practices relating to monitoring and assessment of the ageing of nuclear power plants. Therefore names of participated countries in this documents are those at time of 1991/92 Peer Group discussions. It identifies those common regulatory features which require continuous reinforcement and examples of good regulatory practices that were recommended by senior regulators in the Peer Group discussions.

  19. Modeling and Analysis of Cellular Networks using Stochastic Geometry: A Tutorial

    KAUST Repository

    Elsawy, Hesham; Salem, Ahmed Sultan; Alouini, Mohamed-Slim; Win, Moe Z.

    2016-01-01

    This paper presents a tutorial on stochastic geometry (SG) based analysis for cellular networks. This tutorial is distinguished by its depth with respect to wireless communication details and its focus on cellular networks. The paper starts by modeling and analyzing the baseband interference in a baseline single-tier downlink cellular network with single antenna base stations and universal frequency reuse. Then, it characterizes signal-to-interference-plus-noise-ratio (SINR) and its related performance metrics. In particular, a unified approach to conduct error probability, outage probability, and transmission rate analysis is presented. Although the main focus of the paper is on cellular networks, the presented unified approach applies for other types of wireless networks that impose interference protection around receivers. The paper then extends the unified approach to capture cellular network characteristics (e.g., frequency reuse, multiple antenna, power control, etc.). It also presents numerical examples associated with demonstrations and discussions. To this end, the paper highlights the state-of-the- art research and points out future research directions.

    Chemical analysis based on colour changes recorded with imaging devices is gaining increasing interest. This is due to its several significant advantages, such as simplicity of use, and the fact that it is easily combinable with portable and widely distributed imaging devices, resulting in friendly analytical procedures in many areas that demand out-of-lab applications for in situ and real-time monitoring. This tutorial review covers computer vision-based analytical (CVAC) procedures and systems from 2005 to 2015, a period of time when 87.5% of the papers on this topic were published. The background regarding colour spaces and recent analytical system architectures of interest in analytical chemistry is presented in the form of a tutorial. Moreover, issues regarding images, such as the influence of illuminants, and the most relevant techniques for processing and analysing digital images are addressed. Some of the most relevant applications are then detailed, highlighting their main characteristics. Finally, our opinion about future perspectives is discussed. Copyright © 2015 Elsevier B.V.

  3. Calibration in atomic spectrometry: A tutorial review dealing with quality criteria, weighting procedures and possible curvatures

    International Nuclear Information System (INIS)

    Mermet, Jean-Michel

    2010-01-01

    Calibration is required to obtain analyte concentrations in atomic spectrometry. To take full benefit of it, the adequacy of the coefficient of determination r 2 is discussed, and its use is compared with the uncertainty due to the prediction bands of the regression. Also discussed from a tutorial point of view are the influence of the weighting procedure and of different weighting factors, and the comparison between linear and quadratic regression to cope with curvatures. They are illustrated with examples based on the use of ICP-AES with nebulization and laser ablation, and of LIBS. Use of a calibration graph over several orders of magnitude may be problematic as well as the use of a quadratic regression to cope with possible curvatures. Instrument softwares that allow reprocessing of the calibration by selecting standards around the expected analyte concentration are convenient for optimizing the calibration procedure.

  4. Using Recursive Regression to Explore Nonlinear Relationships and Interactions: A Tutorial Applied to a Multicultural Education Study

    Directory of Open Access Journals (Sweden)

    Kenneth David Strang

    2009-03-01

    Full Text Available This paper discusses how a seldom-used statistical procedure, recursive regression (RR, can numerically and graphically illustrate data-driven nonlinear relationships and interaction of variables. This routine falls into the family of exploratory techniques, yet a few interesting features make it a valuable compliment to factor analysis and multiple linear regression for method triangulation. By comparison, nonlinear cluster analysis also generates graphical dendrograms to visually depict relationships, but RR (as implemented here uses multiple combinations of nominal and interval predictors regressed on a categorical or ratio dependent variable. In similar fashion, multidimensional scaling, multiple discriminant analysis and conjoint analysis are constrained at best to predicting an ordinal dependent variable (as currently implemented in popular software. A flexible capability of RR (again as implemented here is the transformation of factor data (for substituting codes. One powerful RR feature is the ability to treat missing data as a theoretically important predictor value (useful for survey questions that respondents do not wish to answer. For practitioners, the paper summarizes how this technique fits within the generally-accepted statistical methods. Popular software such as SPSS, SAS or LISREL can be used, while sample data can be imported in common formats including ASCII text, comma delimited, Excel XLS, and SPSS SAV. A tutorial approach is applied here using RR in LISREL. The tutorial leverages a partial sample from a study that used recursive regression to predict grades from international student learning styles. Some tutorial portions are technical, to improve the ambiguous RR literature.

  5. Critical analysis of a computer-assisted tutorial on ECG interpretation and its ability to determine competency.

    Science.gov (United States)

    Burke, J F; Gnall, E; Umrudden, Z; Kyaw, M; Schick, P K

    2008-01-01

    We developed a computer-based tutorial and a posttest on ECG interpretation for training residents and determining competency. Forty residents, 6 cardiology fellows, and 4 experienced physicians participated. The tutorial emphasized recognition and understanding of abnormal ECG features. Active learning was promoted by asking questions prior to the discussion of ECGs. Interactivity was facilitated by providing rapid and in-depth rationale for correct answers. Responses to questions were recorded and extensively analyzed to determine the quality of questions, baseline knowledge at different levels of training and improvement of grades in posttest. Posttest grades were used to assess improvement and to determine competency. The questions were found to be challenging, fair, appropriate and discriminative. This was important since the quality of Socratic questions is critical for the success of interactive programs. The information on strengths and weakness in baseline knowledge at different levels of training were used to adapt our training program to the needs of residents. The posttest revealed that the tutorial contributed to marked improvement in feature recognition. Competency testing distinguished between residents with outstanding grades and those who needed remediation. The strategy for critical evaluation of our computer program could be applied to any computer-based educational program, regardless of topic.

  6. Automated problem generation in Learning Management Systems: a tutorial

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available The benefits of solving problems have been widely acknowledged by literature. Its implementation in e–learning platforms can make easier its management and the learning process itself. However, its implementation can also become a very time–consuming task, particularly when the number of problems to generate is high. In this tutorial we describe a methodology that we have developed aiming to alleviate the workload of producing a great deal of problems in Moodle for an undergraduate business course. This methodology follows a six-step process and allows evaluating student’s skills in problem solving, minimizes plagiarism behaviors and provides immediate feedback. We expect this tutorial encourage other educators to apply our six steps process, thus benefiting themselves and their students of its advantages.

    Recent advances in photon counting detection technology have led to significant research interest in X-ray imaging. As a tutorial level review, this paper covers a wide range of aspects related to X-ray photon counting detector characterization. The tutorial begins with a detailed description of the working principle and operating modes of a pixelated X-ray photon counting detector with basic architecture and detection mechanism. Currently available methods and techniques for charactering major aspects including energy response, noise floor, energy resolution, count rate performance (detector efficiency), and charge sharing effect of photon counting detectors are comprehensively reviewed. Other characterization aspects such as point spread function (PSF), line spread function (LSF), contrast transfer function (CTF), modulation transfer function (MTF), noise power spectrum (NPS), detective quantum efficiency (DQE), bias voltage, radiation damage, and polarization effect are also remarked. A cadmium telluride (CdTe) pixelated photon counting detector is employed for part of the characterization demonstration and the results are presented. This review can serve as a tutorial for X-ray imaging researchers and investigators to understand, operate, characterize, and optimize photon counting detectors for a variety of applications.

    Hypothetico-deductive reasoning (HDR) is an essential learning activity and a learning outcome in problem-based learning (PBL). It is important for medical students to engage in the HDR process through argumentation during their small group discussions in PBL. This study aimed to analyze the quality of preclinical medical students' argumentation according to each phase of HDR in PBL. Participants were 15 first-year preclinical students divided into two small groups. A set of three 2-hour discussion sessions from each of the two groups during a 1-week-long PBL unit on the cardiovascular system was audio-recorded. The arguments constructed by the students were analyzed using a coding scheme, which included four types of argumentation (Type 0: incomplete, Type 1: claim only, Type 2: claim with data, and Type 3: claim with data and warrant). The mean frequency of each type of argumentation according to each HDR phase across the two small groups was calculated. During small group discussions, Type 1 arguments were generated most often (frequency=120.5, 43%), whereas the least common were Type 3 arguments (frequency=24.5, 8.7%) among the four types of arguments. The results of this study revealed that the students predominantly made claims without proper justifications; they often omitted data for supporting their claims or did not provide warrants to connect the claims and data. The findings suggest instructional interventions to enhance the quality of medical students' arguments in PBL, including promoting students' comprehension of the structure of argumentation for HDR processes and questioning.

    To compare perception of students on usefulness of interactive tutorials and clinically-oriented problem-solving tutorials. The cross-sectional study was carried out from January 2012 to November 2013 at Bahria University Medical and Dental College, Karachi. The perception of medical students on usefulness of interactive tutorials and clinically-oriented problem-solving tutorials was acquired through a questionnaire distributed to medical students having completed the first two years of studies. The responses on various aspects of learning of physiology were acquired on a scale of poor, good or excellent. The learning abilities and acquired skills were compared in terms of not at all, to some extent, and to great extent. Data was analysed using SPSS 15. Of the hundred students initially enrolled, complete response was obtained from 83(83%). Of them, 47(57%) were females. There was significant difference in understanding of structure and function by clinically-oriented problem-solving tutorials (p=0.04). The students preferred clinically-oriented problem-solving tutorials as far as understating of difficult concepts was concerned (pskills were improved by interactive tutorials (p=0.02) whereas clinical reasoning skills acquired by clinically-oriented problem-solving tutorials was found to be significantly better (pskills were acquired more by clinically-oriented problem-solving tutorials that helped in better understanding of structure and functions.

    To explore healthcare staffs' and managers' perceptions of how and when discrete event simulation modelling can be used as a decision support in improvement efforts. Two focus group discussions were performed. Two settings were included: a rheumatology department and an orthopaedic section both situated in Sweden. Healthcare staff and managers (n=13) from the two settings. Two workshops were performed, one at each setting. Workshops were initiated by a short introduction to simulation modelling. Results from the respective simulation model were then presented and discussed in the following focus group discussion. Categories from the content analysis are presented according to the following research questions: how and when simulation modelling can assist healthcare improvement? Regarding how, the participants mentioned that simulation modelling could act as a tool for support and a way to visualise problems, potential solutions and their effects. Regarding when, simulation modelling could be used both locally and by management, as well as a pedagogical tool to develop and test innovative ideas and to involve everyone in the improvement work. Its potential as an information and communication tool and as an instrument for pedagogic work within healthcare improvement render a broader application and value of simulation modelling than previously reported. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Qualitative research methodologies are being used more frequently in audiology as it allows for a better understanding of the perspectives of people with hearing impairment. This article describes why and how international interdisciplinary qualitative research can be conducted. This paper is based on a literature review and our recent experience with the conduction of an international interdisciplinary qualitative study in audiology. We describe some available qualitative methods for sampling, data collection, and analysis and we discuss the rationale for choosing particular methods. The focus is on four approaches which have all previously been applied to audiologic research: grounded theory, interpretative phenomenological analysis, conversational analysis, and qualitative content analysis. This article provides a review of methodological issues useful for those designing qualitative research projects in audiology or needing assistance in the interpretation of qualitative literature.

    2013-01-01

    Deep unsupervised learning in stochastic recurrent neural networks with many layers of hidden units is a recent breakthrough in neural computation research. These networks build a hierarchy of progressively more complex distributed representations of the sensory data by fitting a hierarchical generative model. In this article we discuss the theoretical foundations of this approach and we review key issues related to training, testing and analysis of deep networks for modeling language and cognitive processing. The classic letter and word perception problem of McClelland and Rumelhart (1981) is used as a tutorial example to illustrate how structured and abstract representations may emerge from deep generative learning. We argue that the focus on deep architectures and generative (rather than discriminative) learning represents a crucial step forward for the connectionist modeling enterprise, because it offers a more plausible model of cortical learning as well as a way to bridge the gap between emergentist connectionist models and structured Bayesian models of cognition.

    Extensive air showers are a very unique phenomenon. In the more than six decades since their discovery by Auger et al. we have learned a great deal about these extremely energetic events and gained deep insights into high-energy phenomena, particle physics and astrophysics. In this Tutorial, Reference Manual and Data Book Peter K. F. Grieder provides the reader with a comprehensive view of the phenomenology and facts of the various types of interactions and cascades, theoretical background, experimental methods, data evaluation and interpretation, and air shower simulation. He discusses astrophysical aspects of the primary radiation and addresses the questions that continue to puzzle researchers. The book is divided into two parts, each in its own separate volume: Part I in Volume I deals mainly with the basic theoretical framework of the processes that determine an air shower and ends with a summary of ways to extract information on the primary radiation from air shower observations.

    Full Text Available This case study describes the use of a web-based synchronous chat application, run during computing tutorials. The chat room was moderated by a paid demonstrator, who assisted and encouraged students whenever possible. Most of the discussion was banter, which acted as a lubricant for relevant factual communication. Students were permitted a degree of anonymity, but nevertheless learned to treat the facility in a useful manner. The application and its mode of employment were found to be both motivating and supportive. Use was evaluated by questionnaire and an analysis of student input. As a result of the experience, it is suggested that abuse will certainly occur and may be minimised by technical improvements, but never eliminated. The Rogerian approach adopted was found to have transferred emphasis from teaching a topic to the learning of generic skills.

    The present study provided a group learning activity called "Ambulatory Medicine Tutorial-AMT" for 5th year medical students in order to facilitate learning experience at ambulatory setting and to improve medical students' clinical performance. This research aimed specifically to study the effect of AMT. Two groups of twenty 5th-year medical students were enrolled during their ambulatory medicine blocks. Each medical student was assigned to have 8 ambulatory sessions. AMT was assigned to one group while the other group only used conventional learning activity. At the end of the present study, total internal medicine scores, patient satisfaction surveys, and data on average time spent on each clinical encounter were collected and compared. The AMT group received a higher total internal medicine score as compared to the conventional group (76.2 +/- 3.6 vs. 72.9 +/- 2.8, p = 0.003). The AMT group could reduce average time spent on each clinical encounter within their first-6 ambulatory sessions while the conventional group could acquire the same skill later in their last 2 ambulatory sessions. There was no significant difference found on comparing patient satisfaction scores between the 2 groups. AMT helped improving medical students' outcomes as shown from higher total internal medicine score as well as quicker improvement during real-life clinical encounters, AMT could be a good alternative learning activity for medical students at ambulatory setting.

    2009-05-01

    Full Text Available [english] Aims: Interactive, student-centered teaching methods have replaced traditional teacher-centered didactic formats in many modern medical curricula in the past few years. However, in the natural sciences such as biochemistry, interactive teaching methods are not well proven. The present study was conducted to compare the effect of the teaching format on the performance of undergraduate students in biochemistry and their evaluation of the respective format. Methods: A total of 421 second-year students were randomized into two groups: The control group was taught in a traditional lecture-like format, whereas the study group dealt with the same topic in an interactive group discussion. At the end of each lesson, students performed a multiple-choice test and completed a questionnaire. The same MCQ test was repeated 4–6 weeks after the last lesson. Results: Students who were taught in a lecture-like format performed significantly better in the first MCQ test immediately after the lesson than students taught in the interactive format. However, in the second MCQ test, there was no difference between the two groups. In the questionnaire, students rated the lecture-based course significantly better than the interactive group discussion. Conclusion: One reason why students prefer a didactic lecture to an interactive group discussion might be due to the subject biochemistry, which is strongly knowledge-based. Students perceived that the transfer of knowledge by a professional lecturer was more effective than the knowledge obtained in a student-centered discussion group. Other reasons might be the method of assessment and the overall design of the curriculum.

  13. Tutorial for Wave Equation Inversion of Skeletonized Data

    KAUST Repository

    2017-04-25

    Full waveform inversion of seismic data is often plagued by cycle skipping problems so that an iterative optimization method often gets stuck in a local minimum. To avoid this problem we simplify the objective function so that the iterative solution can quickly converge to a solution in the vicinity of the global minimum. The objective function is simplified by only using parsimonious and important portions of the data, which are defined as skeletonized data. We now present a mostly non-mathematical tutorial that explains the theory of skeletonized inversion. We also show its effectiveness with examples.

    2003-01-01

    Every day, the number of didactic materials presented through Internet, is greater. However, we have not effective tools to obtain the potential academic yield of such a media. The complexity of the Internet protocols, in spite of the easy handling, makes it almost impossible. In this work, a didactic tool to analyse graphically the navigation through a tutorial on radiation protection is presented. For its visualisation, some subjects related with the biogical effects of radiation and with radiological quantities and units have been selected. The graphical representation shows the tour travelled by the user, in our case students of Medicine, and the time employed in eyeing each one of the nodes. The answers to problems about the contents of each node and its graphical representation in the navigation map allow us to follow the learning progress of the students as well as their standard of navigation. The graphical representation analysis of multiple users permits to detect some of the mistakes in the design of the tutorial and to suggest to the author a method for amending these mistakes. The system is developed on LINEX, but it is easily adaptable to other operating systems. (Author) 7 refs

    The overall aim of this intervention study was to investigate, and measure quantitatively, the psychological effects of structured student tutorial support, on undergraduate students' level of stress, self-esteem and cognitive coping. A quantitative research approach was adopted using a quasi-experimental design (post-test only, non-equivalent control group design) in order to ascertain whether there were any significant differences between the experimental conditions (n=25) and a control group (n=25). The independent variable was structured student tutorial support and the dependent variables were student stress, self-esteem and cognitive coping. A total of 50 subjects were randomly assigned to either the experimental or control group. Quantitative data were collected using: the Student Nurse Stress Index (Jones, M.C., Johnston, D.W., 1997a. The derivation of a 22 item Student Nurse Stress Index, using exploratory, confirmatory and multi-sample confirmatory factor analytic techniques.

Analysis of the stressful effects of hospitalisation and source isolation on coping and psychological constructs. International Journal of Nursing Practice 4(2), 84-97). The methods of data analysis were the application of the t-test and descriptive statistics. The results indicated a significantly lower level of stress in the experimental group (t=-3.85, p=0.001) and a significantly higher self esteem (t=4.11, p=0.001). Results also suggested that students who were provided with structured tutorial support perceived they coped more effectively with their studies (t=4.65, p=0.001). The

  7. Symmetry Theory in Molecular Physics with Mathematica A new kind of tutorial book

    CERN Document Server

    McClain, William

    2008-01-01

    Prof. McClain has indeed produced "a new kind of tutorial book." It is written using the logic engine Mathematica, which permits concrete exploration and development of every concept involved in Symmetry Theory. The book may be read in your hand, or on a computer screen with Mathematica running behind it. It is intended for students of chemistry and molecular physics who need to know mathematical group theory and its applications, either for their own research or for understanding the language and concepts of their field. The book has three major parts: Part I begins with the most elementary symmetry concepts, showing how to express them in terms of matrices and permutations. These are then combined into mathematical groups. Many chemically important point groups are constructed and kept in a Mathematica package for easy reference. No other book gives such easy access to the groups themselves. The automated group construction machinery allows you to tabulate new groups that may be needed in research, such as ...

  8. Integrating Electromagnetic Data with Other Geophysical Observations for Enhanced Imaging of the Earth: A Tutorial and Review

    Science.gov (United States)

    Moorkamp, Max

    2017-09-01

    In this review, I discuss the basic principles of joint inversion and constrained inversion approaches and show a few instructive examples of applications of these approaches in the literature. Starting with some basic definitions of the terms joint inversion and constrained inversion, I use a simple three-layered model as a tutorial example that demonstrates the general properties of joint inversion with different coupling methods. In particular, I investigate to which extent combining different geophysical methods can restrict the set of acceptable models and under which circumstances the results can be biased. Some ideas on how to identify such biased results and how negative results can be interpreted conclude the tutorial part. The case studies in the second part have been selected to highlight specific issues such as choosing an appropriate parameter relationship to couple seismic and electromagnetic data and demonstrate the most commonly used approaches, e.g., the cross-gradient constraint and direct parameter coupling. Throughout the discussion, I try to identify topics for future work. Overall, it appears that integrating electromagnetic data with other observations has reached a level of maturity and is starting to move away from fundamental proof-of-concept studies to answering questions about the structure of the subsurface. With a wide selection of coupling methods suited to different geological scenarios, integrated approaches can be applied on all scales and have the potential to deliver new answers to important geological questions.

We prepared a 5-min video tutorial on the management of shoulder dystocia, using a simulator that includes maternal pelvic and baby models. We performed a survey among obstetric personnel in order to assess their opinion on the tutorial by inviting them to watch the video tutorial and answer an online questionnaire. Five multiple-choice questions were set, focusing on the video's main objectives: clarity, simplicity and usefulness. Following the collection of answers, global and category-weighted analyses were conducted for each question. Out of 956 invitations sent, 482 (50.4%) answered the survey. More than 90% of all categories found the video tutorial to be clinically relevant and clear. For revising the management of shoulder dystocia most obstetric personnel would use the video tutorial together with traditional textbooks. In conclusion, our video tutorial was considered by health personnel as a useful complementary training tool.

    Full Text Available RESUMEN El acompañamiento tutorial, en los últimos años, ha venido cobrando relevancia debido a la implicancia que tiene en el desempeño socioemocional y académico de los estudiantes, es por ello que muchas universidades diseñan planes institucionales que permiten a sus estudiantes fortalecer habilidades y capacidades. En ese sentido, el presente estudio pretende conocer cuáles son las percepciones que tiene un grupo de 30 estudiantes, entre 15 y 18 años, provenientes del interior del país, respecto a las actividades desarrolladas en el programa tutorial del semestre 2014-1. Se empleó un diseño cualitativo de tipo fenomenológico, y para la recolección de datos se emplearon grupos focales y técnicas proyectivas. Los resultados indican que el programa tutorial es concebido por los estudiantes como un espacio de apoyo, escucha que favorece al proceso de adaptación a la vida universitaria, aunque, también, señalan que éste debe ajustarse de acuerdo a las constantes necesidades del grupo. ABSTRACT Tutorial support has become more relevant in recent years because of its implications on the socio-emotional and academic performance of students. Consequently, many universities are implementing institutional plans designed to enable students to strengthen their skills and abilities. In that sense, the study seeks to examine the perception of a group of 30 inland students, between the ages of 15 and 18, with respect to the activities developed during the 2014-1 tutorial program. A qualitative phenomenological design was used, as well as focus groups and projective techniques for the data collection process. The results indicate that students view the tutorial program as a space for support and attention, which contributes to the college-life adjustment process; however, they indicate that it should be adapted to the group’s ever-changing needs.

  11. A Tutorial on Parallel and Concurrent Programming in Haskell

    Peyton Jones, Simon; Singh, Satnam

    This practical tutorial introduces the features available in Haskell for writing parallel and concurrent programs. We first describe how to write semi-explicit parallel programs by using annotations to express opportunities for parallelism and to help control the granularity of parallelism for effective execution on modern operating systems and processors. We then describe the mechanisms provided by Haskell for writing explicitly parallel programs with a focus on the use of software transactional memory to help share information between threads. Finally, we show how nested data parallelism can be used to write deterministically parallel programs which allows programmers to use rich data types in data parallel programs which are automatically transformed into flat data parallel versions for efficient execution on multi-core processors.

    2012-01-01

    Space Telecommunications Radio System (STRS) Architecture Standard provides a NASA standard for software-defined radio. STRS is being demonstrated in the Space Communications and Navigation (SCaN) Testbed formerly known as Communications, Navigation and Networking Configurable Testbed (CoNNeCT). Ground station radios communicating the SCaN testbed are also being written to comply with the STRS architecture. The STRS Architecture Tutorial Overview presents a general introduction to the STRS architecture standard developed at the NASA Glenn Research Center (GRC), addresses frequently asked questions, and clarifies methods of implementing the standard. The STRS architecture should be used as a base for many of NASA s future telecommunications technologies. The presentation will provide a basic understanding of STRS.

    Pereira, Francisco; Mitchell, Tom; Botvinick, Matthew

    2009-03-01

    Interpreting brain image experiments requires analysis of complex, multivariate data. In recent years, one analysis approach that has grown in popularity is the use of machine learning algorithms to train classifiers to decode stimuli, mental states, behaviours and other variables of interest from fMRI data and thereby show the data contain information about them. In this tutorial overview we review some of the key choices faced in using this approach as well as how to derive statistically significant results, illustrating each point from a case study. Furthermore, we show how, in addition to answering the question of 'is there information about a variable of interest' (pattern discrimination), classifiers can be used to tackle other classes of question, namely 'where is the information' (pattern localization) and 'how is that information encoded' (pattern characterization).

    He, Ji-Huan

    2014-11-01

    This tutorial review of fractal-Cantorian spacetime and fractional calculus begins with Leibniz's notation for derivative without limits which can be generalized to discontinuous media like fractal derivative and q-derivative of quantum calculus. Fractal spacetime is used to elucidate some basic properties of fractal which is the foundation of fractional calculus, and El Naschie's mass-energy equation for the dark energy. The variational iteration method is used to introduce the definition of fractional derivatives. Fractal derivative is explained geometrically and q-derivative is motivated by quantum mechanics. Some effective analytical approaches to fractional differential equations, e.g., the variational iteration method, the homotopy perturbation method, the exp-function method, the fractional complex transform, and Yang-Laplace transform, are outlined and the main solution processes are given.

  15. Multi-objective optimization using genetic algorithms: A tutorial

    International Nuclear Information System (INIS)

    Konak, Abdullah; Coit, David W.; Smith, Alice E.

    2006-01-01

    Multi-objective formulations are realistic models for many complex engineering optimization problems. In many real-life problems, objectives under consideration conflict with each other, and optimizing a particular solution with respect to a single objective can result in unacceptable results with respect to the other objectives. A reasonable solution to a multi-objective problem is to investigate a set of solutions, each of which satisfies the objectives at an acceptable level without being dominated by any other solution. In this paper, an overview and tutorial is presented describing genetic algorithms (GA) developed specifically for problems with multiple objectives. They differ primarily from traditional GA by using specialized fitness functions and introducing methods to promote solution diversity

  16. Tutorial on Using Regression Models with Count Outcomes Using R

    Directory of Open Access Journals (Sweden)

    A. Alexander Beaujean

    2016-02-01

    Full Text Available Education researchers often study count variables, such as times a student reached a goal, discipline referrals, and absences. Most researchers that study these variables use typical regression methods (i.e., ordinary least-squares either with or without transforming the count variables. In either case, using typical regression for count data can produce parameter estimates that are biased, thus diminishing any inferences made from such data. As count-variable regression models are seldom taught in training programs, we present a tutorial to help educational researchers use such methods in their own research. We demonstrate analyzing and interpreting count data using Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial regression models. The count regression methods are introduced through an example using the number of times students skipped class. The data for this example are freely available and the R syntax used run the example analyses are included in the Appendix.

    2008-04-01

    We present results from a comparative study of student understanding for students who attended recitation classes that used different teaching methods. The purpose of the study was to evaluate which teaching methods would be the most effective for recitation classes associated with large lectures in introductory physics courses. Student volunteers from our introductory calculus-based physics course at the University of Cincinnati attended a special recitation class that was taught using one of four different teaching methods. A total of 272 students were divided into approximately equal groups for each method. Students in each class were taught the same topic, ``Changes in Energy and Momentum,'' from ``Tutorials in Introductory Physics'' by Lillian McDermott, Peter Shaffer and the Physics Education Group at the University of Washington. The different teaching methods varied in the amount of student and teacher engagement. Student understanding was evaluated through pretests and posttests. Our results demonstrate the importance of the instructor's role in teaching recitation classes. The most effective teaching method was for students working in cooperative learning groups with the instructors questioning the groups using Socratic dialogue. In addition, we investigated student preferences of modes of instruction through an open-ended survey. Our results provide guidance and evidence for the teaching methods which should be emphasized in training course instructors.

  18. Partial Least Squares tutorial for analyzing neuroimaging data

    2014-09-01

    Full Text Available Partial least squares (PLS has become a respected and meaningful soft modeling analysis technique that can be applied to very large datasets where the number of factors or variables is greater than the number of observations. Current biometric studies (e.g., eye movements, EKG, body movements, EEG are often of this nature. PLS eliminates the multiple linear regression issues of over-fitting data by finding a few underlying or latent variables (factors that account for most of the variation in the data. In real-world applications, where linear models do not always apply, PLS can model the non-linear relationship well. This tutorial introduces two PLS methods, PLS Correlation (PLSC and PLS Regression (PLSR and their applications in data analysis which are illustrated with neuroimaging examples. Both methods provide straightforward and comprehensible techniques for determining and modeling relationships between two multivariate data blocks by finding latent variables that best describes the relationships. In the examples, the PLSC will analyze the relationship between neuroimaging data such as Event-Related Potential (ERP amplitude averages from different locations on the scalp with their corresponding behavioural data. Using the same data, the PLSR will be used to model the relationship between neuroimaging and behavioural data. This model will be able to predict future behaviour solely from available neuroimaging data. To find latent variables, Singular Value Decomposition (SVD for PLSC and Non-linear Iterative PArtial Least Squares (NIPALS for PLSR are implemented in this tutorial. SVD decomposes the large data block into three manageable matrices containing a diagonal set of singular values, as well as left and right singular vectors. For PLSR, NIPALS algorithms are used because it provides amore precise estimation of the latent variables. Mathematica notebooks are provided for each PLS method with clearly labeled sections and subsections. The

    2018-04-23

    When estimating the average effect of a binary treatment (or exposure) on an outcome, methods that incorporate propensity scores, the G-formula, or targeted maximum likelihood estimation (TMLE) are preferred over naïve regression approaches, which are biased under misspecification of a parametric outcome model. In contrast propensity score methods require the correct specification of an exposure model. Double-robust methods only require correct specification of either the outcome or the exposure model. Targeted maximum likelihood estimation is a semiparametric double-robust method that improves the chances of correct model specification by allowing for flexible estimation using (nonparametric) machine-learning methods. It therefore requires weaker assumptions than its competitors. We provide a step-by-step guided implementation of TMLE and illustrate it in a realistic scenario based on cancer epidemiology where assumptions about correct model specification and positivity (ie, when a study participant had 0 probability of receiving the treatment) are nearly violated. This article provides a concise and reproducible educational introduction to TMLE for a binary outcome and exposure. The reader should gain sufficient understanding of TMLE from this introductory tutorial to be able to apply the method in practice. Extensive R-code is provided in easy-to-read boxes throughout the article for replicability. Stata users will find a testing implementation of TMLE and additional material in the Appendix S1 and at the following GitHub repository: https://github.com/migariane/SIM-TMLE-tutorial. © 2018 The Authors.

    Federline, M.

    2004-01-01

    The subject of this seminar was 'Strategy Selection for Decommissioning of Nuclear Facilities' and it was clear throughout that safety of D and D operations continues to be of importance in that selection, particularly in regard to the condition of the site and the risk it represents. In this context, it was specifically noted that a safety case for D and D needs to be kept under continuous review and needs to be flexible enough to accommodate appropriate modification as the work progresses and the nature of the risk changes. It was also noted that the hazard presented by a facility in decommissioning is normally significantly less than during the operating phase (for a reactor, for example, the fuel has been removed, there are no pressurised systems and no high operating temperatures). The changing plant configuration and the reduced hazard potential lead to the observation that the safety management arrangements also need appropriate adjustment from those employed during the operating phase. It was recalled that a Task Group of the WPDD is addressing safety issues on an ongoing basis. It was also clear from the detailed presentations that techniques for D and D are already available and that they have been successfully demonstrated in practice. Nevertheless, because the costs of dismantling nuclear facilities make up at least a third of the overall D and D costs, there seemed to be a strong case for continuing R and D in this area in order to improve the cost effectiveness of such techniques. It was noted, however, that the extent of such R and D is now somewhat limited and that further work is first required to identify the most effective areas for future R and D projects. Also, throughout the seminar, it was emphasised that strategy selection must remain flexible since it is highly dependent on financing, societal input, technical feasibility, waste management options, and regulatory processes. Against this well-established background, Allan Duncan, as

    Electrochemistry is truly an interdisciplinary science and plays an important role in different branches of science and technology. The present Discussion Meet on ElectroAnalytical Techniques (DM- ELANTE-2008) is focused on the update of various electroanalytical techniques which have brought out a substantial change in electroanalytical chemistry. The aim of this Discussion Meet is to provide a forum to all the electroanalytical scientists to discuss their recent findings and information, learn from the mutual experiences and interests, and to promote cooperation both nationally and internationally. It is proposed to have tutorial lectures as well as invited talks during the Discussion Meet on various electroanalytical techniques including Electrochemical Impedance Spectroscopy (EIS), Spectro-electrochemistry, Scanning Electrochemical Microscopy (SECM), Electrochemical Quartz Crystal Microbalance (EQCM), Surface Plasmon Resonance (SPR) etc. Papers relevant to INIS are indexed separately

  2. Discussion in Postsecondary Classrooms

    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

    2014-10-01

    Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

    2017-01-01

    Neurofeedback is attracting renewed interest as a method to self-regulate one’s own brain activity to directly alter the underlying neural mechanisms of cognition and behavior. It not only promises new avenues as a method for cognitive enhancement in healthy subjects, but also as a therapeutic tool. In the current article, we present a review tutorial discussing key aspects relevant to the development of electroencephalography (EEG) neurofeedback studies. In addition, the putative mechanisms underlying neurofeedback learning are considered. We highlight both aspects relevant for the practical application of neurofeedback as well as rather theoretical considerations related to the development of new generation protocols. Important characteristics regarding the set-up of a neurofeedback protocol are outlined in a step-by-step way. All these practical and theoretical considerations are illustrated based on a protocol and results of a frontal-midline theta up-regulation training for the improvement of executive functions. Not least, assessment criteria for the validation of neurofeedback studies as well as general guidelines for the evaluation of training efficacy are discussed. PMID:28275344

    Computer programming course is theoretical. Sufficient practice is necessary to facilitate conceptual understanding and encouraging creativity in designing computer programs/animation. The development of tutorial video in an Android-based blended learning is needed for students’ guide. Using Android-based instructional material, students can independently learn anywhere and anytime. The tutorial video can facilitate students’ understanding about concepts, materials, and procedures of programming/animation making in detail. This study employed a Research and Development method adapting Thiagarajan’s 4D model. The developed Android-based instructional material and tutorial video were validated by experts in instructional media and experts in physics education. The expert validation results showed that the Android-based material was comprehensive and very feasible. The tutorial video was deemed feasible as it received average score of 92.9%. It was also revealed that students’ conceptual understanding, skills, and creativity in designing computer program/animation improved significantly.

    1996-05-01

    This progress report describes the development and student use of World-Wide-Web-based prelaboratory exercises in senior-level Instrumental Analysis during the 1995 Fall semester. The laboratory preparation exercises contained hypermedia tutorials and multiple-choice questions that were intended to familiarize the students with the experiments and instrumentation before their laboratory session. The overall goal of our work is to explore ways in which computer and network technology can be applied in education to improve the cost-effectiveness and efficacy of teaching. The course material can be accessed at http://www.chem.vt.edu/chem-ed/4114/Fall1995.html. The students were instructed to read their experimental procedure and to do the relevant laboratory preparation exercise. The individual tutorial documents were primarily text that provided basic theoretical and experimental descriptions of analytical and instrumental methods. The documents included hyperlinks to basic concepts, simple schematics, and color graphics of experimental set-ups or instrumentation. We chose the World-Wide Web (WWW) as the delivery platform for this project because of the ease of developing, distributing, and modifying hypermedia material in a client-server system. The disadvantage of the WWW is that network bandwidth limits the size and sophistication of the hypermedia material. To minimize internet transfer time, the individual documents were kept short and usually contained no more than 3 or 4 inline images. After reading the tutorial the students answered several multiple-choice questions. The figure shows one example of a multiple-choice question and the response page. Clicking on the "Submit answer" button calls a *.cgi file, which contains instructions in the PERL interpretive language, that generates the response page and saves the date, time, and student's answer to a file on the server. Usage and student perception of the on-line material was evaluated from server logs and

  13. Online Pedagogical Tutorial Tactics Optimization Using Genetic-Based Reinforcement Learning.

    2015-01-01

    Tutorial tactics are policies for an Intelligent Tutoring System (ITS) to decide the next action when there are multiple actions available. Recent research has demonstrated that when the learning contents were controlled so as to be the same, different tutorial tactics would make difference in students' learning gains. However, the Reinforcement Learning (RL) techniques that were used in previous studies to induce tutorial tactics are insufficient when encountering large problems and hence were used in offline manners. Therefore, we introduced a Genetic-Based Reinforcement Learning (GBML) approach to induce tutorial tactics in an online-learning manner without basing on any preexisting dataset. The introduced method can learn a set of rules from the environment in a manner similar to RL. It includes a genetic-based optimizer for rule discovery task by generating new rules from the old ones. This increases the scalability of a RL learner for larger problems. The results support our hypothesis about the capability of the GBML method to induce tutorial tactics. This suggests that the GBML method should be favorable in developing real-world ITS applications in the domain of tutorial tactics induction.

    Full Text Available This study assessed student perceptions about an online information literacy tutorial, CORE (Comprehensive Online Research Education, to plan for the next generation of tutorials. The CORE tutorial includes seven modules: “Planning Your Project,” “Topic Exploration,” “Types of Information,” “Search Tools,” “Search Strategies,” “Evaluating Sources,” and “Copyright, Plagiarism, and Citing Sources.” First-year students in biology and nursing courses responded to a survey after they completed the CORE modules. The students liked learning through an online tutorial. They thought that the tutorial could be improved with shorter modules and the addition of video and audio content. Few students reported learning important information from the “Copyright, Plagiarism, and Citing Sources,” “Evaluating Resources,” and “Types of Information” modules. They suggested topics for additional tutorials: how to use library databases and Microsoft Excel; how to evaluate the quality of information, how to cite references in a bibliography, and how to find statistics.

    Radar altimetry is very much a technique expanding its applications. Even If quite a lot of effort has been invested for oceanography users, the use of Altimetry data for cryosphere application, especially with the new ESA CryoSat-2 mission data is still somehow tedious for new Altimetry data products users. ESA and CNES therfore developed the Basic Radar Altimetry Toolbox a few years ago, and are improving and upgrading it to fit new missions and the growing number of altimetry uses. The Basic Radar Altimetry Toolbox is an "all-altimeter" collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data. The software is able: - to read most distributed radar altimetry data, from ERS-1 & 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, Jason- 2, CryoSat, the future Saral missions and is ready for adaptation to Sentinel-3 products - to perform some processing, data editing and statistic, - and to visualize the results. It can be used at several levels/several ways: - as a data reading tool, with APIs for C, Fortran, Matlab and IDL - as processing/extraction routines, through the on-line command mode - as an educational and a quick-look tool, with the graphical user interface As part of the Toolbox, a Radar Altimetry Tutorial gives general information about altimetry, the technique involved and its applications, as well as an overview of past, present and future missions, including information on how to access data and additional software and documentation. It also presents a series of data use cases, covering all uses of altimetry over ocean, cryosphere and land, showing the basic methods for some of the most frequent manners of using altimetry data. It is an opportunity to teach remote sensing with practical training. It has been available since April 2007, and had been demonstrated during training courses and scientific meetings. About 2000 people downloaded it (Summer 2011), with many "newcomers" to altimetry among them

    Radar altimetry is very much a technique expanding its applications. If quite a lot of efforts have been made for oceanography users (including easy-to-use data), the use of those data for cryosphere application, especially with the new ESA CryoSat-2 mission data is still somehow tedious, especially for new Altimetry data products users. ESA and CNES thus had the Basic Radar Altimetry Toolbox developed a few years ago, and are improving and upgrading it to fit new missions and the growing number of altimetry uses. The Basic Radar Altimetry Toolbox is an "all-altimeter" collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data. The software is able: - to read most distributed radar altimetry data, from ERS-1 & 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, Jason- 2, CryoSat and the future Saral missions, - to perform some processing, data editing and statistic, - and to visualize the results. It can be used at several levels/several ways: - as a data reading tool, with APIs for C, Fortran, Matlab and IDL - as processing/extraction routines, through the on-line command mode - as an educational and a quick-look tool, with the graphical user interface As part of the Toolbox, a Radar Altimetry Tutorial gives general information about altimetry, the technique involved and its applications, as well as an overview of past, present and future missions, including information on how to access data and additional software and documentation. It also presents a series of data use cases, covering all uses of altimetry over ocean, cryosphere and land, showing the basic methods for some of the most frequent manners of using altimetry data. It is an opportunity to teach remote sensing with practical training. It has been available from April 2007, and had been demonstrated during training courses and scientific meetings. About 1200 people downloaded it (Summer 2010), with many "newcomers" to altimetry among them, including teachers

    The roundtable discussion began with remarks by the chairman who pointed out the complicated nature of plutonium chemistry. Judging from the papers presented at this symposium, he noticed a pattern which indicated to him the result of diminished funding for investigation of basic plutonium chemistry and funding focused on certain problem areas. Dr. G.L. silver pointed to plutonium chemists' erroneous use of a simplified summary equation involving the disproportionation of Pu(EV) and their each of appreciation of alpha coefficients. To his appreciation of alpha coefficients. To his charges, Dr. J.T. Bell spoke in defense of the chemists. This discussion was followed by W.W. Schulz's comments on the need for experimental work to determine solubility data for plutonium in its various oxidation states under geologic repository conditions. Discussion then turned to plutonium pyrachemical process with Dana C. Christensen as the main speaker. This paper presents edited versions of participants' written version

  19. OAI-PMH for resource harvesting, tutorial 2

    2005-01-01

    A variety of examples have arisen in which the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) has been used for applications beyond bibliographic metadata interchange. One of these examples is the use of OAI-PMH to harvest resources and not just metadata. Advanced resource discovery and preservations capabilities are possible by combining complex object formats such as MPEG-21 DIDL, METS and SCORM with the OAI-PMH. In this tutorial, we review community conventions and practices that have provided the impetus for resource harvesting. We show how the introduction of complex object formats for the representation of resources leads to a robust, OAI-PMH-based framework for resource harvesting. We detail how complex object formats fit in the OAI-PMH data model, and how (compound) digital objects can be represented using a complex object format for exposure by an OAI-PMH repository. We also cover tools that are available for the implementation of an OAI-PMH-based resource harvesting solution. Fu...

    2015-06-01

    Given the growing prominence of computational modeling in the acquisition research community, we present a tutorial on how to use computational modeling to investigate learning strategies that underlie the acquisition process. This is useful for understanding both typical and atypical linguistic development. We provide a general overview of why modeling can be a particularly informative tool and some general considerations when creating a computational acquisition model. We then review a concrete example of a computational acquisition model for complex structural knowledge referred to as syntactic islands. This includes an overview of syntactic islands knowledge, a precise definition of the acquisition task being modeled, the modeling results, and how to meaningfully interpret those results in a way that is relevant for questions about knowledge representation and the learning process. Computational modeling is a powerful tool that can be used to understand linguistic development. The general approach presented here can be used to investigate any acquisition task and any learning strategy, provided both are precisely defined.

    Microsimulation models are becoming increasingly common in the field of decision modeling for health. Because microsimulation models are computationally more demanding than traditional Markov cohort models, the use of computer programming languages in their development has become more common. R is a programming language that has gained recognition within the field of decision modeling. It has the capacity to perform microsimulation models more efficiently than software commonly used for decision modeling, incorporate statistical analyses within decision models, and produce more transparent models and reproducible results. However, no clear guidance for the implementation of microsimulation models in R exists. In this tutorial, we provide a step-by-step guide to build microsimulation models in R and illustrate the use of this guide on a simple, but transferable, hypothetical decision problem. We guide the reader through the necessary steps and provide generic R code that is flexible and can be adapted for other models. We also show how this code can be extended to address more complex model structures and provide an efficient microsimulation approach that relies on vectorization solutions.

    Full Text Available Oscillatory neuronal activity may provide a mechanism for dynamic network coordination. Rhythmic neuronal interactions can be quantified using multiple metrics, each with their own advantages and disadvantages. This tutorial will review and summarize current analysis methods used in the field of invasive and non-invasive electrophysiology to study the dynamic connections between neuronal populations. First, we review metrics for functional connectivity, including coherence, phase synchronization, phase-slope index, and Granger causality, with the specific aim to provide an intuition for how these metrics work, as well as their quantitative definition. Next, we highlight a number of interpretational caveats and common pitfalls that can arise when performing functional connectivity analysis, including the common reference problem, the signal to noise ratio problem, the volume conduction problem, the common input problem, and the trial sample size bias problem. These pitfalls will be illustrated by presenting a set of MATLAB-scripts, which can be executed by the reader to simulate each of these potential problems. We discuss of how these issues can be addressed using current methods.

  4. The equatorial E-region and its plasma instabilities: a tutorial

    Full Text Available In this short tutorial we first briefly review the basic physics of the E-region of the equatorial ionosphere, with emphasis on the strong electrojet current system that drives plasma instabilities and generates strong plasma waves that are easily detected by radars and rocket probes. We then discuss the instabilities themselves, both the theory and some examples of the observational data. These instabilities have now been studied for about half a century (!, beginning with the IGY, particularly at the Jicamarca Radio Observatory in Peru. The linear fluid theory of the important processes is now well understood, but there are still questions about some kinetic effects, not to mention the considerable amount of work to be done before we have a full quantitative understanding of the limiting nonlinear processes that determine the details of what we actually observe. As our observational techniques, especially the radar techniques, improve, we find some answers, but also more and more questions. One difficulty with studying natural phenomena, such as these instabilities, is that we cannot perform active cause-and-effect experiments; we are limited to the inputs and responses that nature provides. The one hope here is the steadily growing capability of numerical plasma simulations. If we can accurately simulate the relevant plasma physics, we can control the inputs and measure the responses in great detail. Unfortunately, the problem is inherently three-dimensional, and we still need somewhat more computer power than is currently available, although we have come a long way.

  5. Quantification of low molecular weight compounds by MALDI imaging mass spectrometry - A tutorial review.

    2017-07-01

    Matrix-assisted laser desorption/ionization (MALDI)-mass spectrometry imaging (MSI) permits label-free in situ analysis of chemical compounds directly from the surface of two-dimensional biological tissue slices. It links qualitative molecular information of compounds to their spatial coordinates and distribution within the investigated tissue. MALDI-MSI can also provide the quantitative amounts of target compounds in the tissue, if proper calibration techniques are performed. Obviously, as the target molecules are embedded within the biological tissue environment and analysis must be performed at their precise locations, there is no possibility for extensive sample clean-up routines or chromatographic separations as usually performed with homogenized biological materials; ion suppression phenomena therefore become a critical side effect of MALDI-MSI. Absolute quantification by MALDI-MSI should provide an accurate value of the concentration/amount of the compound of interest in relatively small, well-defined region of interest of the examined tissue, ideally in a single pixel. This goal is extremely challenging and will not only depend on the technical possibilities and limitations of the MSI instrument hardware, but equally on the chosen calibration/standardization strategy. These strategies are the main focus of this article and are discussed and contrasted in detail in this tutorial review.

    Full Text Available Introduction: Due to increased cognitive and social congruence with their tutees, near peer teachers (NPTs may be capable of more effectively delivering course material. This study examines NPTs as pathology tutors alongside more traditional teachers (e.g., consultants and registrars to explore their acceptability, effectiveness, and years of ‘distance’ between tutors and tutees. Method: In total, 240 first- and second-year undergraduate medical students were taught set material in a pathology tutorial setting by NPTs (fourth-year medical students, registrars, or consultants. Learners were then asked to provide feedback using a 15-item, Likert-type scale. Results: On 11 of the 15 items, there were no significant differences in students’ median ratings. However, NPTs were perceived to be significantly more approachable than consultants, more aware of learning outcomes, more receptive to student input, and more invested in exam success. Compared with second-year students, first-year students showed a preference towards registrar tutors in terms of perceived gain of knowledge and use of time. In contrast, second-year students showed a preference towards NPTs, who provided more perceived knowledge gain and investment in exam success. No significant differences were found regarding consultant tutors. Discussion: Perhaps due to increased congruence with tutees, NPTs show promise as tutors within medical curricula. This provides advantages not only to tutees, but also to tutors – who may gain vital teaching experience and offer an effective supplement to ‘traditional’ faculty educators.

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

    Research suggests that introductory physics students often have difficulty using a concept in contexts different from the ones in which they learned it without explicit guidance to help them make the connection between the different contexts. We have been investigating advanced students' learning of quantum mechanics concepts and have developed interactive tutorials which strive to help students learn these concepts. Two such tutorials, focused on the Mach-Zehnder interferometer (MZI) and the double-slit experiment (DSE), help students learn how to use the concept of "which-path" information to reason about the presence or absence of interference in these two experiments in different situations. After working on a pretest that asked students to predict interference in the MZI with single photons and polarizers of various orientations placed in one or both paths of the MZI, students worked on the MZI tutorial which, among other things, guided them to reason in terms of which-path information in order to predict interference in similar situations. We investigated the extent to which students were able to use reasoning related to which-path information learned in the MZI tutorial to answer analogous questions on the DSE (before working on the DSE tutorial). After students worked on the DSE pretest they worked on a DSE tutorial in which they learned to use the concept of which-path information to answer questions about interference in the DSE with single particles with mass sent through the two slits and a monochromatic lamp placed between the slits and the screen. We investigated if this additional exposure to the concept of which-path information promoted improved learning and performance on the DSE questions with single photons and polarizers placed after one or both slits. We find evidence that both tutorials promoted which-path information reasoning and helped students use this reasoning appropriately in contexts different from the ones in which they had learned

The new electricity market in Ontario has introduced the energy trader, who enters into a contract with the consumer, based on the spot price set by the Independent Electricity Market Operator. Every contract has a fixed price payer as well as floating-price payers. If the floating price for a given amount of energy is higher than the fixed price, then the consumer gets the difference. Confusion, however, arises with the purchase of retail physical power in the market, particularly in deciding a fixed rate that the consumer will be paying. Different billing options were also discussed with emphasis on mid to large retail customers that have portfolios in the tens of MW and up to 100 MW or more. figs.

    2016-12-01

    To examine the relationship between students' collaborative performance in a problem-based learning (PBL) environment and their personality traits. Methods:This retrospective, cross-sectional study was conducted using student data of a PBL program between 2013 and 2014 at Sungkyunkwan University School of Medicine, Seoul, South Korea. Eighty students were included in the study. Student data from the Temperament and Character Inventory were used as a measure of their personality traits. Peer evaluation scores during PBL were used as a measure of students' collaborative performance. Results: Simple regression analyses indicated that participation was negatively related to harm avoidance and positively related to persistence, whereas preparedness for the group work was negatively related to reward dependence. On multiple regression analyses, low reward dependence remained a significant predictor of preparedness. Grade-point average (GPA)  was negatively associated with novelty seeking and cooperativeness and was positively associated with persistence.  Conclusion: Medical students who are less dependent on social reward are more likely to complete assigned independent work to prepare for the PBL tutorials. The findings of this study can help educators better understand and support medical students who are at risk of struggling in collaborative learning environments.
