    Engaging students in active learning is linked to positive learning outcomes. This study aims to synthesise the peer-reviewed literature about 'active learning' in college science classroom settings. Using the methodology of an integrative literature review, 337 articles archived in the Educational Resources Information Center (ERIC) are examined. Four categories of in-class activities emerge: (i) individual non-polling activities, (ii) in-class polling activities, (iii) whole-class discussion or activities, and (iv) in-class group activities. Examining the collection of identified in-class activities through the lens of a theoretical framework informed by constructivism and social interdependence theory, we synthesise the reviewed literature to propose the active learning strategies (ALSs) model and the instructional decisions to enable active learning (IDEAL) theory. The ALS model characterises in-class activities in terms of the degrees to which they are designed to promote (i) peer interaction and (ii) social interdependence. The IDEAL theory includes the ALS model and provides a framework for conceptualising different levels of the general concept 'active learning' and how these levels connect to instructional decision-making about using in-class activities. The proposed ALS model and IDEAL theory can be utilised to inform instructional decision-making and future research about active learning in college science courses.

    This paper describes the design and outcomes of an educational intervention undertaken to improve the quality of delivery of a fourth-year engineering elective course - Industrial Wastewater and Solid Waste Management at the University of Queensland. The objective was to increase the level of active participation of students in planned active-learning classroom activities, including whole-class discussions and small group project-type work. According to a flipped classroom model, new online material in the form of webcasts was proposed to students before class. Students reacted very positively to the webcasts: the percentage of students viewing the webcast before planned workshop sessions ranged between 80% and 92% over the five weeks of the intervention. Enhanced engagement led also to increased attendance (85-92% at workshop sessions), and remarkable active participation in class (half of observed teams were ∼80% active). Remarkably, team performance as quantified by their report marks linearly correlated with the level of active participation in class.

  7. On the modernist elements of ‘Ithaca’ chapter in Joyce’s Ulysses: Engaging students in class discussion

    Directory of Open Access Journals (Sweden)

    Roohollah Datli Beigi

    2012-01-01

    Full Text Available   James Joyce's Ulysses is one of the hall-marks of modernism in the realm of the novel. In this novel, Joyce breaks away from old patterns, employs new techniques, and presents the modern state of man as well as his soul-lacking indeterminate communication with others. Freud's theories on the unique and private quality of man's mode of consciousness and the meddling of the past with present, stressed the twentieth-century man's ill-condition and his position among his fellow beings. Joyce portrays the modern man in his favorite chapter, ‘Ithaca,’ which has certain features that make the narrative structure in complete step with Joyce's themes regarding the modern man. This paper is an attempt to show how the human race is perceived by Joyce, revealing how the employed elements depict a modern picture of the modern man. This chapter contains many questions and answers that can be discussed in class and students can be engaged in novel-based dialogues and class discussion as an EFL practice.

    Introduction School physical activity and other activities with the body in focus hold the potential to benefit student’s positive mental health and psychosocial well-being. In-class activities (ICAs) (e.g. energizers, active breaks, brain breaks) can positively influence social connectedness......, physical self-perception, motivation and emotions. However, if all students are to benefit from the potential qualities of ICA, an inclusive environment is crucial. The purpose of this study was to investigate the implementation and impact of ICA in Danish public schools. Methods ICA is one of three...... tool to promote positive mental health and well-being in schools for all students. For many teachers, ICA is a challenging task, which calls for both competence development, supportive structures, materials and local school leadership....

    2014-01-01

    We investigated some of the key features of effective active learning by comparing the outcomes of three different methods of implementing active-learning exercises in a majors introductory biology course. Students completed activities in one of three treatments: discussion, writing, and discussion + writing. Treatments were rotated weekly between three sections taught by three different instructors in a full factorial design. The data set was analyzed by generalized linear mixed-effect models with three independent variables: student aptitude, treatment, and instructor, and three dependent (assessment) variables: change in score on pre- and postactivity clicker questions, and coding scores on in-class writing and exam essays. All independent variables had significant effects on student performance for at least one of the dependent variables. Students with higher aptitude scored higher on all assessments. Student scores were higher on exam essay questions when the activity was implemented with a writing component compared with peer discussion only. There was a significant effect of instructor, with instructors showing different degrees of effectiveness with active-learning techniques. We suggest that individual writing should be implemented as part of active learning whenever possible and that instructors may need training and practice to become effective with active learning.

  11. Inverse correlation between promoter strength and excision activity in class 1 integrons.

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Class 1 integrons are widespread genetic elements that allow bacteria to capture and express gene cassettes that are usually promoterless. These integrons play a major role in the dissemination of antibiotic resistance among Gram-negative bacteria. They typically consist of a gene (intI encoding an integrase (that catalyzes the gene cassette movement by site-specific recombination, a recombination site (attI1, and a promoter (Pc responsible for the expression of inserted gene cassettes. The Pc promoter can occasionally be combined with a second promoter designated P2, and several Pc variants with different strengths have been described, although their relative distribution is not known. The Pc promoter in class 1 integrons is located within the intI1 coding sequence. The Pc polymorphism affects the amino acid sequence of IntI1 and the effect of this feature on the integrase recombination activity has not previously been investigated. We therefore conducted an extensive in silico study of class 1 integron sequences in order to assess the distribution of Pc variants. We also measured these promoters' strength by means of transcriptional reporter gene fusion experiments and estimated the excision and integration activities of the different IntI1 variants. We found that there are currently 13 Pc variants, leading to 10 IntI1 variants, that have a highly uneven distribution. There are five main Pc-P2 combinations, corresponding to five promoter strengths, and three main integrases displaying similar integration activity but very different excision efficiency. Promoter strength correlates with integrase excision activity: the weaker the promoter, the stronger the integrase. The tight relationship between the aptitude of class 1 integrons to recombine cassettes and express gene cassettes may be a key to understanding the short-term evolution of integrons. Dissemination of integron-driven drug resistance is therefore more complex than previously thought.

    This study was performed to compare the antibacterial activities of three cavity disinfectants [chlorhexidine (CHX), NaOCl, urushiol] and to evaluate their effect on the microtensile bond strength of Scotchbond Universal Adhesive (3M-ESPE, St. Paul, MN, USA) in class I cavities. In both experiments, class I cavities were prepared in dentin. After inoculation with Streptococcus mutans, the cavities of control group were rinsed and those of CHX, NaOCl and urushiol groups were treated with each disinfectant. Standardized amounts of dentin chips were collected and number of S. mutans was determined. Following the same cavity treatment, same adhesive was applied in etch-and-rinse mode. Then, microtensile bond strength was evaluated. The number of S. mutans was significantly reduced in the cavities treated with CHX, NaOCl, and urushiol compared with control group (p<0.05). However, there was a significant bond strength reduction in NaOCl group, which showed statistical difference compared to the other groups (p<0.05).

    The application of active video games (AVGs) during cardiac rehabilitation (CR) sessions could potentially facilitate patient adherence. The feasibility, safety, and efficacy of in-class AVG supplementation as an alternative to conventional phase 2 programs were investigated. A pilot, evaluator-blinded, intention-to-treat, randomized controlled trial recruited 32 low-moderate risk CR participants and allocated them to conventional or AVG-supplemented exercise. Both groups experienced equal exercise loads for 6 weeks. Patients were assessed at baseline, end of the program, and after an 8-week followup. Adherence and safety-related outcomes were the primary endpoints. Secondary outcomes included change in exercise capacity, daily physical activity (PA), energy expenditure (EE), and psychometric profiling. Patients (males 81%; 60 ± 10 years) presented with typical cardiovascular risk factors and similar baseline characteristics. Participants did not perceive an increased risk of injury and were more interactive. At the end of the program, there was a lower tendency for dropping out (6% vs 19%, P > .05), a significant improvement in PA (322 vs 247 arbitrary acceleration units/min, P = .047) and related EE per body weight (13 vs 11 kcal/kg/d, P = .04) among AVG participants compared with controls. No significant differences between groups for adverse medical events, exercise capacity, affect toward exercise, anxiety, depression, or quality-of-life changes were reported. The additional use of AVGs during CR sessions is feasible, safe, and significantly improved daily PA and EE. A dropout reduction trend among its users, which needs to be confirmed in a larger trial, raises awareness to AVG supplementation as a promising strategy to increase CR adherence.

    So, your research is mentioned or gets discussed in social media, in blogs and other online channels. Do you care? Should you care? Will this exposure result in better science? Researchers probably should care, and most likely policy makers already care, because it matters how research, funded by them, is being portrayed in society. We have pretty solid ideas about how to quantify the impact of research on itself. This has been studied for decades in the fields of informetrics, bibliometrics and scientometrics. But how do you quantify the societal impact of research? You will need to assume that this impact can be measured in principle, and that is possible to come up with a recipe that quantifies this impact. Assuming that there is a societal impact seems quite reasonable for most disciplines in science. It is definitely true for parts of astronomy and physics. Just think of the attention given to the LHC or to the hunt for exoplanets. Enter the concept of "alternative metrics", or "altmetrics". As a result of the growing interest in altmetrics, various services (like the websites impactstory.org and altmetric.com) claim to have found a way to quantify the societal impact of research, either in a person-centric or publication-centric way. On this poster we explore, using data provided by altmetric.com, how astronomy fits in this altmetrics picture. How do popular science articles compare to those in the core astronomy journals? Is there any correlation between the altmetric measure and indicators like downloads, reads or citations? We briefly discuss the benefits that altmetrics might offer and the pitfalls involved in quantifying such measures.

    2016-06-01

    An active learning activity was used to engage students and enhance in-class learning of cell cycle regulation in a PharmD level integrated biological sciences course. The aim of the present study was to determine the effectiveness and perception of the in-class activity. After completion of a lecture on the topic of cell cycle regulation, students completed a 10-question multiple-choice quiz before and after engaging in the activity. The activity involved reading of a headline news article published by ScienceDaily.com entitled "One Gene Lost Equals One limb Regained." The name of the gene was deleted from the article and, thus, the end goal of the activity was to determine the gene of interest by the description in the story. The activity included compiling a list of all potential gene candidates before sufficient information was given to identify the gene of interest (p21). A survey was completed to determine student perceptions of the activity. Quiz scores improved by an average of 20% after the activity (40.1 ± 1.95 vs. 59.9 ± 2.14,Pactivity, found the news article interesting, and believed that the activity improved their understanding of cell cycle regulation. The majority of students agreed that the in-class activity piqued their interest for learning the subject matter and also agreed that if they understand a concept during class, they are more likely to want to study that concept outside of class. In conclusion, the activity improved in-class understanding and enhanced interest in cell cycle regulation. Copyright © 2016 The American Physiological Society.

  2. First-Year and Non-First-Year Student Expectations Regarding In-Class and Out-of-Class Learning Activities in Introductory Biology †

    Brown, Tanya L.; Brazeal, Kathleen R.; Couch, Brian A.

    2017-01-01

    National calls for teaching transformation build on a constructivist learning theory and propose that students learn by actively engaging in course activities and interacting with other students. While interactive pedagogies can improve learning, they also have the potential to challenge traditional norms regarding class participation and learning strategies. To better understand the potential openness of students to interactive teaching practices, we administered a survey during the first week of two sections of an introductory biology course to characterize how students envisioned spending time during class as well as what activities they expected to complete outside of class during non-exam weeks and in preparation for exams. Additionally, we sought to test the hypothesis that the expectations of first-year students differed from those of non-first-year students. Analyses of closed-ended and open-ended questions revealed that students held a wide range of expectations and that most students expressed expectations consistent with some degree of transformed teaching. Furthermore, first-year students expected more active learning in class, more out-of-class coursework during non-exam weeks, and more social learning strategies than non-first-year students. We discuss how instructor awareness of incoming student expectations might be used to promote success in introductory science courses. PMID:28512514

    The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students' fitness knowledge and fitness achievement. One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called "CrossFit Challenge" during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.

    Full Text Available The scores obtained by the military students are very important as a lot of opportunities depend on them: the choice of the branch, selection for different in and off-campus activities, the appointment to the workplace and so on. A qualifier, regardless of its form of effective expression, can make a difference in a given context of issuing a value judgment, in relation to the student's performance assessment. In our research we tried to find out what motives students, what determines them to get actively involved in the tasks they are given and the ways we can improve their participation in classes and assignments. In order to have an educated generation we need to have not only well prepared teachers but ones that are open-minded, flexible and in pace with the methodological novelties that can improve the teaching learning process in class. Along the years we have noticed that in classes where students constituted a cohesive group with an increasing degree of interaction between members, the results were better than in a group that did not appreciate team-work. In this article we want to highlight the fact that a teacher can bring to class the appropriate methods and procedures can contribute decisively to the strengthening of the group cohesion and high scores.

    To analyse the activity, content, contributors, and influencers of the Twitter discussion on urologic oncology. We performed a comprehensive quantitative and qualitative Twitter analysis for the hashtags #prostatecancer, #bladdercancer, #kidneycancer, and #testicularcancer. Symplur was used to analyse activity over different time periods and the top influencers of the Twitter discussion. Tweet Archivist and Twitonomy analysis tools were used to assess characteristics of content and contributors. Twitter discussion on urologic oncology in 2014 contained 100,987 tweets created by 39,326 participants. Mean monthly tweet activity was 6,603±2,183 for #prostatecancer, 866±923 for #testicularcancer, 457±477 for #bladdercancer and 401±504 for #kidneycancer. Twitter activity increased by 41% in 2013 and by 122% in 2014. The content analysis detected awareness, cancer, and risk as frequently mentioned words in urologic oncology tweets. Prevalently used related hashtags were the general hashtag #cancer, awareness hashtags, and the respective cancer/urology tag ontology hashtags. Contributors originated from 41 countries on 6 continents and had a mean of 5,864±4,747 followers. They tweeted from platforms on exclusively mobile devices (39%) more frequently than from desktop devices (29%). Health care organizations accounted for 58% of the top influencers in all cancers. The largest proportion of physicians were among the #prostatecancer and #kidneycancer (each 9%) influencers and individual contributors were most frequent in the discussion on #kidneycancer (57%) and #testicularcancer (50%). There is a significant and growing activity in the Twitter discussion on urologic oncology, particularly on #prostatecancer. The Twitter discussion is global, social, and mobile, and merits attention of stakeholders in health care as a promising communication tool. Copyright © 2016 Elsevier Inc. All rights reserved.

These dynamics can be influenced by student social identities. One social identity that has been unexamined in the context of undergraduate biology is the spectrum of lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) identities. In this exploratory interview study, we probed the experiences and perceptions of seven students who identify as part of the LGBTQIA community. We found that students do not always experience the undergraduate biology classroom to be a welcoming or accepting place for their identities. In contrast to traditional lectures, active-learning classes increase the relevance of their LGBTQIA identities due to the increased interactions among students during group work. Finally, working with other students in active-learning classrooms can present challenges and opportunities for students considering their LGBTQIA identity. These findings indicate that these students' LGBTQIA identities are affecting their experience in the classroom and that there may be specific instructional practices that can mitigate some of the possible obstacles. We hope that this work can stimulate discussions about how to broadly make our active-learning biology classes more inclusive of this specific population of students. © 2016 K. M. Cooper and S. E.

    Full Text Available In this article we problematize the issues related to teacher’s training in the English language amidst the emersion of new literacies, especially those mediated by digital technologies, based in my experience both as a teacher and a researcher in Degree Courses in Languages, both classroom based and distance learning. Based in referential about teachers’ beliefs, reflexive practices, new literacies, and teachers’ training for the use of technologies, we focus our experience in the development of institutional material for a distance learning teaching degree course, describing some of the activities developed as discussion forums. With that, our aim is to discuss ways to promote the reflection of future teachers about their beliefs and experiences, and the interaction of these with teaching concepts and theories, allowing them to establish connections between theory and practice during practice - in other words, through their engagement in online activities of a subject in a Supervised Internship in English.

    Full Text Available Recreational trail runners often participate in online community forums where they can freely read posted messages, join discussions and/or introduce new discussion topics. This tool can enhance learning as runners connect with other trail runners and reflect on how they can better organize their own practice. Studying forum activity would provide greater insight into the relationship between field practice and dedicated forums. The aim of this study was therefore to detect the topics discussed online by trail runners in order to understand how they collectively look for solutions that help them adapt to issues that emerge during actual practice. The discussion topics (n = 171 on the forum hosted by the Raidlight brand were examined using inductive content analysis, which distinguished two general dimensions. The first dimension was training and had four first-order themes (i.e., “specific trail running sessions”, “complementary trail running sessions”. “training plans” and “specific questions about races” grouped into two second-order themes (i.e., “training session contents” and “structure and schedule”. The second dimension was health and had seven first-order themes (i.e., “tendinitis”, “muscle issues”, “foot issues”, “sprains and fractures”, “pain”, “physiology” and “substances and practitioners” grouped into two second-order themes (i.e., “pain and injury” and “prevention”. The results indicate that the issues that trail runners discuss on forums are significant and that the successions of questions and solutions are a fruitful means for building, enriching and adjusting their activity as they cope with constraints. As a practical consequence, suggestions for improving such online platforms are made.

    Full Text Available The study investigated perceived ease of use and usefulness of Google Hangouts as an instructional/learning tool. Forty-two teacher education students at U.S and Japanese universities participated in an online cross-cultural activity using Google Hangouts and discussed cultural differences between the two countries and their teaching philosophies. After the activity, students responded to a survey to evaluate the ease of use and usefulness of Google Hangouts. Qualitative data were also collected through the survey to examine their overall learning experience. The results indicated that Google Hangouts is a useful instructional tool, but not easy to use. Although technical problems occurred during the conference, the activity provided valuable experiences for both U.S. and Japanese students. The study provides suggestions for how Google Hangouts can be integrated into online classrooms based on the findings.

  20. Social network activation: the role of health discussion partners in recovery from mental illness.

    In response to health problems, individuals may strategically activate their social network ties to help manage crisis and uncertainty. While it is well-established that social relationships provide a crucial safety net, little is known about who is chosen to help during an episode of illness. Guided by the Network Episode Model, two aspects of consulting others in the face of mental illness are considered. First, we ask who activates ties, and what kinds of ties and networks they attempt to leverage for discussing health matters. Second, we ask about the utility of activating health-focused network ties. Specifically, we examine the consequences of network activation at time of entry into treatment for individuals' quality of life, social satisfaction, ability to perform social roles, and mental health functioning nearly one year later. Using interview data from the longitudinal Indianapolis Network Mental Health Study (INMHS, N = 171), we focus on a sample of new patients with serious mental illness and a group with less severe disorders who are experiencing their first contact with the mental health treatment system. Three findings stand out. First, our results reveal the nature of agency in illness response. Whether under a rational choice or habitus logic, individuals appear to evaluate support needs, identifying the best possible matches among a larger group of potential health discussants. These include members of the core network and those with prior mental health experiences. Second, selective activation processes have implications for recovery. Those who secure adequate network resources report better outcomes than those who injudiciously activate network ties. Individuals who activate weaker relationships and those who are unsupportive of medical care experience poorer functioning, limited success in fulfilling social roles, and lower social satisfaction and quality of life later on. Third, the evidence suggests that social networks matter above and

    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.

    This trial was conducted to determine the dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) of the first in class NEDD8-activating enzyme (NAE) inhibitor, pevonedistat, and to investigate pevonedistat pharmacokinetics and pharmacodynamics in patients with acute myeloid leukaemia (AML) and myelodysplastic syndromes (MDS). Pevonedistat was administered via a 60-min intravenous infusion on days 1, 3 and 5 (schedule A, n = 27), or days 1, 4, 8 and 11 (schedule B, n = 26) every 21-days. Dose escalation proceeded using a standard '3 + 3' design. Responses were assessed according to published guidelines. The MTD for schedules A and B were 59 and 83 mg/m(2) , respectively. On schedule A, hepatotoxicity was dose limiting. Multi-organ failure (MOF) was dose limiting on schedule B. The overall complete (CR) and partial (PR) response rate in patients treated at or below the MTD was 17% (4/23, 2 CRs, 2 PRs) for schedule A and 10% (2/19, 2 PRs) for schedule B. Pevonedistat plasma concentrations peaked after infusion followed by elimination in a biphasic pattern. Pharmacodynamic studies of biological correlates of NAE inhibition demonstrated target-specific activity of pevonedistat. In conclusion, administration of the first-in-class agent, pevonedistat, was feasible in patients with MDS and AML and modest clinical activity was observed. © 2015 John Wiley & Sons Ltd.

    The amount of time allocated to physical activity in schools is declining. Time-efficient physical activity solutions that demonstrate their impact on academic achievement-related outcomes are needed to prioritize physical activity within the school curricula. "FUNtervals" are 4-min, high-intensity interval activities that use whole-body actions to complement a storyline. The purpose of this study was to (i) explore whether FUNtervals can improve selective attention, an executive function posited to be essential for learning and academic success; and (ii) examine whether this relationship is predicted by students' classroom off-task behaviour. Seven grade 3-5 classes (n = 88) were exposed to a single-group, repeated cross-over design where each student's selective attention was compared between no-activity and FUNtervals days. In week 1, students were familiarized with the d2 test of attention and FUNterval activities, and baseline off-task behaviour was observed. In both weeks 2 and 3 students completed the d2 test of attention following either a FUNterval break or a no-activity break. The order of these breaks was randomized and counterbalanced between weeks. Neither motor nor passive off-task behaviour predicted changes in selective attention following FUNtervals; however, a weak relationship was observed for verbal off-task behaviour and improvements in d2 test performance. More importantly, students made fewer errors during the d2 test following FUNtervals. In supporting the priority of physical activity inclusion within schools, FUNtervals, a time efficient and easily implemented physical activity break, can improve selective attention in 9- to 11-year olds.

    Bacterial enterotoxin superantigens bind directly to HLA class II molecules (HLA-DR) expressed on both APC and activated human T cells, and simultaneously bind to certain V beta chains of the TCR. In this report, we compared early T cell signaling events in human alloantigen-stimulated T cells when...... activated by HLA-DR ligation through antibody cross-linking or by direct enterotoxin superantigen binding. Both types of stimuli induced tyrosine phosphorylation of phosphatidylinositol-specific phospholipase C gamma 1 (PLC gamma 1) and an increase in intracellular calcium concentration; however......, superantigen-induced signaling was stronger than class II ligation alone. Antibody-mediated ligation of HLA-DR with CD3 resulted in augmented PLC gamma 1 activation and increased calcium mobilization, consistent with a mechanism of superantigen activity through a combination of class II and CD3/Ti signals...

In this study, we evaluated the impact of teaching physicians how to better communicate the benefits and risks of prostate cancer treatments on the willingness of patients to choose active surveillance. Decisions related to cancer are often guided by emotions and biases that lead most patients to seek radical treatment; however, we demonstrated that if discussions are framed differently, these biases can be overcome and more patients will choose active surveillance.

    Pevonedistat (TAK-924/MLN4924) is a novel inhibitor of NEDD8-activating enzyme (NAE) with single-agent activity in relapsed/refractory acute myeloid leukemia (AML). We performed a phase 1b study of pevonedistat (PEV) with azacitidine (AZA) based on synergistic activity seen preclinically. Primary objectives included safety and tolerability, and secondary objectives included pharmacokinetics (PK) and disease response. Patients ≥60 years with treatment-naive AML (unfit for standard induction therapy) received PEV 20 or 30 mg/m 2 IV on days 1, 3, and 5 combined with fixed-dose AZA (75 mg/m 2 IV/subcutaneously) on days 1 to 5, 8, and 9, every 28 days. The most common treatment-emergent adverse events were constipation (48%), nausea (42%), fatigue (42%), and anemia (39%). In total, 11 deaths were observed and considered unrelated to study therapy by the investigators. Transient elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were dose limiting. The recommended phase 2 dose (RP2D) of PEV in this combination is 20 mg/m 2 PEV PK was not altered by the addition of AZA. Overall response rate (ORR) based on an intent-to-treat analysis was 50% (20 complete remissions [CRs], 5 complete remission with incomplete peripheral count recovery, 7 partial remissions [PRs]), with an 8.3-month median duration of remission. In patients receiving ≥6 cycles of therapy (n = 23, 44%), ORR was 83%. In patients with TP53 mutations, the composite CR/PR rate was 80% (4/5). Two of these patients stayed on study for >10 cycles. Baseline bone marrow blast percentage or cytogenetic/molecular risk did not influence ORR.

    Sugar 4-epimerization reactions are important for the production of rare sugars and their derivatives, which have various potential industrial applications. For example, the production of tagatose, a functional sweetener, from fructose by sugar 4-epimerization is currently constrained because a fructose 4-epimerase does not exist in nature. We found that class II D-fructose-1,6-bisphosphate aldolase (FbaA) catalyzed the 4-epimerization of D-fructose-6-phosphate (F6P) to D-tagatose-6-phosphate (T6P) based on the prediction via structural comparisons with epimerase and molecular docking and the identification of the condensed products of C3 sugars. In vivo, the 4-epimerization activity of FbaA is normally repressed. This can be explained by our results showing the catalytic efficiency of D-fructose-6-phosphate kinase for F6P phosphorylation was significantly higher than that of FbaA for F6P epimerization. Here, we identified the epimerization reactions and the responsible catalytic residues through observation of the reactions of FbaA and L-rhamnulose-1-phosphate aldolases (RhaD) variants with substituted catalytic residues using different substrates. Moreover, we obtained detailed potential epimerization reaction mechanism of FbaA and a general epimerization mechanism of the class II aldolases L-fuculose-1-phosphate aldolase, RhaD, and FbaA. Thus, class II aldolases can be used as 4-epimerases for the stereo-selective synthesis of valuable carbohydrates.

    Full Text Available In class II and III obese individuals, lifestyle intervention is the first step to achieve weight loss and treat obesity-related comorbidities before considering bariatric surgery. A systematic review, meta-analysis, and meta-regression were performed to assess the impact of lifestyle interventions incorporating a physical activity (PA component on health outcomes of class II and III obese individuals.An electronic search was conducted in 4 databases (Medline, Scopus, CINAHL and Sportdiscus. Two independent investigators selected original studies assessing the impact of lifestyle interventions with PA components on anthropometric parameters, cardiometabolic risk factors (fat mass, blood pressure, lipid and glucose metabolism, behaviour modification (PA and nutritional changes, and quality of life in adults with body mass index (BMI ≥ 35 kg/m2. Estimates were pooled using a random-effect model (DerSimonian and Laird method. Heterogeneity between studies was assessed by the Cochran's chi-square test and quantified through an estimation of the I².Of the 3,170 identified articles, 56 met our eligibility criteria, with a large majority of uncontrolled studies (80%. The meta-analysis based on uncontrolled studies showed significant heterogeneity among all included studies. The pooled mean difference in weight loss was 8.9 kg (95% CI, 10.2-7.7; p < 0.01 and 2.8 kg/m² in BMI loss (95% CI, 3.4-2.2; p < 0.01. Long-term interventions produced superior weight loss (11.3 kg compared to short-term (7.2 kg and intermediate-term (8.0 kg interventions. A significant global effect of lifestyle intervention on fat mass, waist circumference, blood pressure, total cholesterol, LDL-C, triglycerides and fasting insulin was found (p<0.01, without significant effect on HDL-C and fasting blood glucose.Lifestyle interventions incorporating a PA component can improve weight and various cardiometabolic risk factors in class II and III obese individuals.

    This study aims to investigate the ways to improve the cementitious properties of steel slag. The results show that the cementitious phase of steel slag is composed of silicate and aluminate, but the large particles of these phases make a very small contribution to the cementitious properties of steel slag. RO phase (CaO-FeO-MnO-MgO solid solution), Fe(3)O(4), C(2)F and f-CaO make no contribution to the cementitious properties of steel slag. A new kind of steel slag with more cementitious phase and less RO phase can be obtained by removing some large particles. This new steel slag possesses better cementitious properties than the original steel slag. The large particles can be used as fine aggregates for concrete. Adding regulating agent high in CaO and SiO(2) during manufacturing process of steel slag to increase the cementitious phase to inert phase ratio is another way to improve its cementitious properties. The regulating agent should be selected to adapt to the specific steel slag and the alkalinity should be increased as high as possible on the premise that the f-CaO content does not increase. The cooling rate should be enhanced to improve the hydration activity of the cementitious phase at the early ages and the grindability of steel slag. Copyright © 2010 Elsevier B.V.

    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.

    As the popularization of cultural relics and the rapid development of cultural tourism industry, a large number of cultural relic tourism resources goes into public eyes. Activation of relics has became an important way for tourist to contact and understand culture relics. The way of how to properly interpret the historical sense and cultural uniqueness to the masses of tourists in order to achieve social service functions of relic resources has always been research focal point of site protection and utilization, so nowadays it has important significance to protection and utilization of heritage resources in our country. From the point of activation of relics and based on the analysis of resource characteristic, the paper in depth discuss ways of activation of relics of the Old Summer Palace, in order to provide reference for sustainable development of sites tourism in China.

  1. Evaluation of Forensic DNA Traces When Propositions of Interest Relate to Activities: Analysis and Discussion of Recurrent Concerns

    When forensic scientists evaluate and report on the probative strength of single DNA traces, they commonly rely on only one number, expressing the rarity of the DNA profile in the population of interest. This is so because the focus is on propositions regarding the source of the recovered trace material, such as “the person of interest is the source of the crime stain.” In particular, when the alternative proposition is “an unknown person is the source of the crime stain,” one is directed to think about the rarity of the profile. However, in the era of DNA profiling technology capable of producing results from small quantities of trace material (i.e., non-visible staining) that is subject to easy and ubiquitous modes of transfer, the issue of source is becoming less central, to the point that it is often not contested. There is now a shift from the question “whose DNA is this?” to the question “how did it get there?” As a consequence, recipients of expert information are now very much in need of assistance with the evaluation of the meaning and probative strength of DNA profiling results when the competing propositions of interest refer to different activities. This need is widely demonstrated in day-to-day forensic practice and is also voiced in specialized literature. Yet many forensic scientists remain reluctant to assess their results given propositions that relate to different activities. Some scientists consider evaluations beyond the issue of source as being overly speculative, because of the lack of relevant data and knowledge regarding phenomena and mechanisms of transfer, persistence and background of DNA. Similarly, encouragements to deal with these activity issues, expressed in a recently released European guideline on evaluative reporting (Willis et al., 2015), which highlights the need for rethinking current practice, are sometimes viewed skeptically or are not considered feasible. In this discussion paper, we select and discuss

    For DOE's Used Fuel Disposition Campaign (UFDC), international collaboration is a beneficial and cost-effective strategy for advancing disposal science with regards to multiple disposal options and different geologic environments. While the United States disposal program focused solely on Yucca Mountain tuff as host rock over the past decades, several international programs have made significant progress in the characterization and performance evaluation of other geologic repository options, most of which are very different from the Yucca Mountain site in design and host rock characteristics. Because Yucca Mountain was so unique (e.g., no backfill, unsaturated densely fractured tuff), areas of direct collaboration with international disposal programs were quite limited during that time. The decision by the U.S. Department of Energy to no longer pursue the disposal of high-level radioactive waste and spent fuel at Yucca Mountain has shifted UFDC's interest to disposal options and geologic environments similar to those being investigated by disposal programs in other nations. Much can be gained by close collaboration with these programs, including access to valuable experience and data collected over recent decades. Such collaboration can help to efficiently achieve UFDC's long-term goals of conducting 'experiments to fill data needs and confirm advanced modeling approaches' (by 2015) and of having a 'robust modeling and experimental basis for evaluation of multiple disposal system options' (by 2020). This report discusses selected opportunities of active international collaboration, with focus on both Natural Barrier System (NBS) and Engineered Barrier System (EBS) aspects and those opportunities that provide access to field data (and respective interpretation/modeling) or allow participation in ongoing field experiments. This discussion serves as a basis for the DOE/NE-53 and UFDC planning process for FY12 and beyond.

    Full Text Available Abstract Background Medical students in clerkship are continuously confronted with real and relevant patient problems. To support clinical problem solving skills, students perform a Critical Appraisal of a Topic (CAT task, often resulting in a paper. Because such a paper may contain errors, students could profit from discussion with peers, leading to paper revision. Active peer discussion by a Computer Supported Collaborative Learning (CSCL environment show positive medical students perceptions on subjective knowledge improvement. High students’ activity during discussions in a CSCL environment demonstrated higher task-focussed discussion reflecting higher levels of knowledge construction. However, it remains unclear whether high discussion activity influences students’ decisions revise their CAT paper. The aim of this research is to examine whether students who revise their critical appraisal papers after discussion in a CSCL environment show more task-focussed activity and discuss more intensively on critical appraisal topics than students who do not revise their papers. Methods Forty-seven medical students, stratified in subgroups, participated in a structured asynchronous online discussion of individual written CAT papers on self-selected clinical problems. The discussion was structured by three critical appraisal topics. After the discussion, the students could revise their paper. For analysis purposes, all students’ postings were blinded and analysed by the investigator, unaware of students characteristics and whether or not the paper was revised.

    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.

    Many patients with chronic kidney disease (CKD) have difficulty becoming actively engaged in the pursuit of preemptive living donor kidney transplantation. The Talking About Live Kidney Donation (TALK) Study was a randomized controlled trial of the effectiveness of educational and social worker interventions designed to encourage early discussions and active pursuit of preemptive living donor kidney transplantation in patients with progressive CKD. We recruited participants with progressive CKD from academically affiliated nephrology practices in Baltimore, MD. Participants randomly received: (1) usual care (routine care with their nephrologists), the (2) TALK education intervention (video and booklet), or the (3) TALK social worker intervention (video and booklet plus patient and family social worker visits). We followed participants for 6 months to assess their self-reported achievement of behaviors reflecting their discussions about and/or pursuit of living donor kidney transplantation (discussions with family, discussions with physicians, initiating recipient evaluation, completing recipient evaluation, and identifying a potential living donor). We assessed outcomes through a questionnaire at 1-, 3-, and 6-months follow-up. Participants receiving usual care with their nephrologists (n = 44), TALK education (n = 43), and the TALK social worker (n = 43) were similar at baseline. TALK Study interventions improved participants' living donor kidney transplantation discussion and pursuit behaviors, with the social worker leading to greater patient activation (participants' predicted probability of achieving living donor kidney transplantation discussions, evaluations, or donor identification over 6 months): probabilities were 30% (95% CI, 20%-46%), 42% (95% CI, 33%-54%), and 58% (95% CI, 41%-83%), respectively, in the usual care, TALK education, and TALK social worker groups (P = 0.03). Our population was well educated and mostly insured, potentially limiting

    Full Text Available In this paper, I describe the face of modern civil justice and discuss four paradoxes which justify re-evaluating the role of the judge responsible for reviewing class action settlements, in light of modern judicial culture. I also critically evaluate the existing procedures applicable to the fairness review as well as the judicial role described in the caselaw and doctrine, before suggesting a revised, three-parted role for the reviewing judge in the class action settlement context. Ultimately, I suggest that to reach fairness of process and outcome in class action settlements, judges should remain active and creative in their inquisitorial assessment of proposed class action settlements. They should also remain conciliatory, participating in the search for solutions regarding the proposed settlement, always seeking to find the truth (and what is “just” about the proposed settlement, in the utmost respect for the rights of absent class members, the respect of their interests, and the additional consideration of the interests of the defendants and of the public. Dans cet article, je présente l’état de la face de la justice civile moderne et je discute quatre paradoxes qui justifient une réévaluation du rôle du juge responsable de la révision et de l’approbation d’un règlement de recours collectif, à la lumière de la culture juridique moderne. Je propose aussi une évaluation critique des procédures en place s’appliquant à l’évaluation du caracters équitable de la transaction, de même que le rôle du juge décrit dans la jurisprudence et la doctrine, avant de suggérer un rôle révisé. Ce rôle modifié se décline en trois parties. Finalement, je suggère que pour atteindre l’équité de procédure et de résultat dans le cas de règlements en recours collectif, les juges devraient demeurer actifs et créatifs en enquêtant pour évaluer des règlements proposés dans les cas de recours collectifs.

    Succeeding theories and empirical investigations have often been built over conceptual understanding to develop talent education. Opportunities provided by society are crucial at every point in the talent-development process. Abilities differ and can vary among boys and girls. Although they have some responsibility for their own growth and development, the educational system and psychosocial variables influence on the successful development of high levels of education. This research explores students’ attitudes to science education to establish why many disengage with the subject in class and what can be done to reverse this trend to produce unimaginable scientific and practical benefits to society. The control group is students from several schools with traditional education in Iran and the experimental group is teams who have taken part in several activities such as national and international tournaments (2005-2013). This research has two parts: 1—how innovation in teaching and 2—discussion and controversy in class can improve science education and cause motivation. The average scores are divided into 5 ranges in both experimental and traditional groups. As shown by Spearman’s correlation rank (ρ) the difference between boys’ and girls’ average scores is about (2.71) in the control group but it has decreased to (0.29) in the experimental group. The main point of discussion is on problems in class which advance a set of interrelated scientific arguments for outstanding achievement.

    Activities were introduced in Kashiwa city in the Tokyo metropolitan area to correspond to the elevated environmental radiation level after the disaster of the Fukushima Daiichi nuclear power plant. These were based on a strong cooperation between local governments and experts. Ambient dose rate and radioactivity of foodstuff produced inside of the city have been monitored. Representative ambient dose rates around living environments have almost already become their original levels of the pre-accident because of the decontamination activity, natural washout and effective half-lives of radioactivity. The internal annual dose due to radioactive cesium under the policy of 'Local Production for Local Consumption' is estimated as extremely low comparing the variation range due to natural radioactivity. Systematic survey around a retention basin has been started. All of these latest monitoring data would be one of the core information for the policy making as well as a cost-benefit discussion and risk communication. (authors)

    Instructors often give prompts that encourage students to articulate their beliefs and conceptions, as well as encourage students to understand the thoughts of their peers. This reflective discourse is used in a calculus-based introductory physics class at Lane Community College, where the instructor explicitly has discourse goals integrated into his course structure. We investigate whether students utilize this discourse when solving problems outside of the classroom context. We interviewed groups of students after the end of spring term, 2012. The students were asked to solve open-ended problems, with analysis focused on whether students applied this reflective discourse. Students were asked a series of follow-up questions to reflect upon their experiences in the course.

    2018-03-01

    Church and Haschenburger (2017, https://doi.org/10.1002/2016WR019675) make helpful distinctions around the issue of defining the active layer, with which we agree. We propose expanding discussion and definition of the "active layer" in fluvial bedload transport to include the concept of the "morphological active layer." This is particularly applicable to laterally unstable rivers (such as braided rivers) in which progressive morphological change over short time periods is the process by which much of the bedload transport occurs. The morphological active layer is also distinguished by variable lateral and longitudinal extent continuity over a range of flows and transport intensity. We suggest that the issue of forms of active layer raised by Church and Haschenburger opens up an important discussion on the nature of bedload transport in relation to river morpho-dynamics over the range of river types.

    Full Text Available The article is devoted to the importance of selecting the optimal methods of stimulation and motivation for learning. In modern conditions it is very important that the teacher did not give the students ready knowledge, but pointed out the way for the acquisition of knowledge, taught them to gain knowledge. This demands from the philologist the choice of effective forms of working with texts of different types and styles of speech, listening, speaking. In this connection a special attention should be paid to the lessons of speech development. There is a special group of methods to stimulate the development of communicative competence. Among them, the method of discussion, which is increasingly being used during the Russian language lessons. The specificity of using this method in class for teaching Russian as a foreign language, its basic functions (teaching, developing, educating are considered. The key rules for conducting a discussion at the Russian language classes, the main and additional functions-roles of the teacher, the participants, the minute-taker are analyzed. The advantages of the discussion in Russian in comparison to the discussion in the students’ native language are summarized.

    Recent studies in the field of special education have shown that in combination with software technology, high-tech commercial products can be applied as useful assistive technology devices to help people with disabilities. This study extended this concept to turn a Nintendo Wii Remote Controller into a high-performance limb action detector, in order to evaluate whether two students with Attention Deficit Hyperactivity Disorder (ADHD) could reduce their hyperactive behavior through an active reminder and stimulation in the form of the participants' preferred rewards. This study focused on one particular hyperactive behavior common to both students: standing up arbitrarily during class. The active reminder was in the form of vibration feedback provided via the built-in function of the Wii Remote Controller, which was controlled and triggered by a control system to remind participants when they were engaging in standing behavior. This study was performed according to a multiple baseline design across participants. The results showed that both participants significantly improved their control over their hyperactive behavior during the intervention phase, and retained this effective performance in the maintenance phase. The practical and developmental implications of the findings are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    In recognition of the potential benefits of ethanol and the merits of encouraging value-added agricultural development, a committee was formed to develop options for the role of the Ontario Ministry of Agriculture and Food in the further development of the ethanol industry in Ontario. A consultation with interested parties produced a discussion paper which begins with an outline of the role of ethanol as an alternative fuel. Ethanol issues which require industry consideration are presented, including the function of ethanol as a gasoline oxygenate or octane enhancer, environmental impacts, energy impacts, agricultural impacts, trade and fiscal implications, and regulation. The ethanol industry and distribution systems in Ontario are then described. The current industry consists of one ethanol plant and over 30 retail stations. The key issue for expanding the industry is the economics of producing ethanol. At present, production of ethanol in the short term depends on tax incentives amounting to 23.2 cents/l. In the longer term, a significant reduction in feedstock costs and a significant improvement in processing technology, or equally significant gasoline price increases, will be needed to create a sustainable ethanol industry that does not need incentives. Possible roles for the Ministry are identified, such as support for ethanol research and development, financial support for construction of ethanol plants, and active encouragement of market demand for ethanol-blended gasolines

    This article is a research conducted with qualitative approach with various case studies underlining a strategy that becomes the basis for classroom management. The article discusses and links to the learning revolution that becomes today’s demands, including a discussion that analyses the condition of learners. The article based its data preliminary study conducted in Manado in the province of North Sulawesi in Indonesia. This region has its own characteristics with the encounter of Muslims and the Protestant community for century. Due to its uniqueness 3 Moslem schools and 3 Protestant schools in Manado were selected to study. Data collection was conducted for a year, from May 2016 to April 2017.

The stages include observation and in-depth interviews and conducting focus group discussions. Two important thought about the essence of learning strategy and learning revolution in class were shared briefly within this article.

  4. 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.”

  8. Using self-efficacy theory to develop interventions that help older people overcome psychological barriers to physical activity: a discussion paper.

    Lee, Ling-Ling; Arthur, Antony; Avis, Mark

    2008-11-01

    Only a fifth of older people undertake a level of physical activity sufficient to lead to health benefit. Misconceptions about the ageing process and beliefs about the costs and benefits of exercise in late life may result in unnecessary self-imposed activity restriction. Thus, adhering to a physical activity can be difficult particularly when the benefits of exercise are often not immediate. Many of the barriers to engaging in physical activity among older people are attitudinal. It is therefore important to take account of the non-physical aspects of physical activity intervention programmes, such as increasing confidence. Self-efficacy is a widely applied theory used to understand health behaviour and facilitate behavioural modification, such as the increase of physical activity. This paper aims to examine the ways in which self-efficacy theory might be used in intervention programmes designed to overcome psychological barriers for increasing physical activity among older people. A number of studies have demonstrated that exercise self-efficacy is strongly associated with the amount of physical activity undertaken. Evidence from some trials supports the view that incorporating the theory of self-efficacy into the design of a physical activity intervention is beneficial. Physical activity interventions aimed at improving the self perception of exercise self-efficacy can have positive effects on confidence and the ability to initiate and maintain physical activity behaviour. There are a number of ways for nurses to facilitate older people to draw on the four information sources of self-efficacy: performance accomplishments, vicarious learning, verbal encouragement, and physiological and affective states. Research challenges that future studies need to address include the generalisability of exercise setting, the role of age as an effect modifier, and the need for more explicit reporting of how self-efficacy is operationalised in interventions.

  9. Are treatment effects of neurofeedback training in children with ADHD related to the successful regulation of brain activity? A review on the learning of regulation of brain activity and a contribution to the discussion on specificity.

    Full Text Available While issues of efficacy and specificity are crucial for the future of neurofeedback training, there may be alternative designs and control analyses to circumvent the methodological and ethical problems associated with double-blind placebo studies. Surprisingly, most NF studies do not report the most immediate result of their NF training, i.e. whether or not children with ADHD gain control over their brain activity during the training sessions. For the investigation of specificity, however, it seems essential to analyze the learning and adaptation processes that take place in the course of the training and to relate improvements in self-regulated brain activity across training sessions to behavioral, neuropsychological and electrophysiological outcomes. To this aim, a review of studies on neurofeedback training with ADHD patients, which include the analysis of learning across training sessions or relate training performance to outcome, is presented. Methods on how to evaluate and quantify learning of EEG regulation over time are discussed. Non-learning has been reported in a small number of ADHD-studies, but has not been a focus of general methodological discussion so far. For this reason, selected results from the brain-computer interface (BCI research on the so-called brain-computer illiteracy, the inability to gain control over one’s brain activity, are also included. It is concluded that in the discussion on specificity, more attention should be devoted to the analysis of EEG regulation performance in the course of the training and its impact on clinical outcome. It is necessary to improve the knowledge on characteristic cross-session and within-session learning trajectories in ADHD and to provide the best conditions for learning.

  1. A Comparative Discussion of the Catalytic Activity and CO2-Selectivity of Cu-Zr and Pd-Zr (Intermetallic Compounds in Methanol Steam Reforming

    Norbert Köpfle

    2017-02-01

    Full Text Available The activation and catalytic performance of two representative Zr-containing intermetallic systems, namely Cu-Zr and Pd-Zr, have been comparatively studied operando using methanol steam reforming (MSR as test reaction. Using an inverse surface science and bulk model catalyst approach, we monitored the transition of the initial metal/intermetallic compound structures into the eventual active and CO2-selective states upon contact to the methanol steam reforming mixture. For Cu-Zr, selected nominal stoichiometries ranging from Cu:Zr = 9:2 over 2:1 to 1:2 have been prepared by mixing the respective amounts of metallic Cu and Zr to yield different Cu-Zr bulk phases as initial catalyst structures. In addition, the methanol steam reforming performance of two Pd-Zr systems, that is, a bulk system with a nominal Pd:Zr = 2:1 stoichiometry and an inverse model system consisting of CVD-grown ZrOxHy layers on a polycrystalline Pd foil, has been comparatively assessed. While the CO2-selectivity and the overall catalytic performance of the Cu-Zr system is promising due to operando formation of a catalytically beneficial Cu-ZrO2 interface, the case for Pd-Zr is different. For both Pd-Zr systems, the low-temperature coking tendency, the high water-activation temperature and the CO2-selectivity spoiling inverse WGS reaction limit the use of the Pd-Zr systems for selective MSR applications, although alloying of Pd with Zr opens water activation channels to increase the CO2 selectivity.

    The panel discussion opened with a question concerning whether true quantification of myocardial sympathetic presynaptic function or receptor density can be obtained with currently available radiopharmaceuticals. What are the relative advantages of the two general approaches that have been proposed for quantification: (1) The assessment of tracer distribution volume in tissue following bolus injection and (2) quantification based on tracer displacement kinetics following administration of excess unlabeled tracer. It was pointed out that tracer kinetics for the delineation of presynaptic and postsynaptic binding sites by radiopharmaceuticals or radiolabeled receptor antagonists are rather complex, reflecting several physiologic processes that are difficult to separate. Several approaches were examined. The possibility of regional definition of receptor density by PET was questioned and it was noted that regions of interest can be applied to calculate regional receptor kinetics. However, due to the limited spatial resolution of PET, only average transmural values can be determined. The discussion then turned to the discrepancy between the known sparse parasympathetic innervation of the heart and the high density of muscarinic receptors observed with PET. Experiences with MIBG imaging were reported, including uptake in the transplanted heart and interaction of drugs with MIBG uptake

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Biliary complications often lead to acute and chronic liver injury after orthotopic liver transplantation (OLT). Bile composition and secretion depend on the integrated action of all the components of the biliary tree, starting from hepatocytes. Fatty livers are often discarded as grafts for OLT, since they are extremely vulnerable to conventional cold storage (CS). However, the insufficiency of donors has stimulated research to improve the usage of such marginal organs as well as grafts. Our group has recently developed a machine perfusion system at subnormothermic temperature (20°C; MP20) that allows a marked improvement in preservation of fatty and even of normal rat livers as compared with CS. We sought to evaluate the response of the biliary tree of fatty liver to MP20, and a suitable marker was essential to this purpose. Alkaline phosphatase (AlkP, EC 3.1.3.1), frequently used as marker of membrane transport in hepatocytes and bile ducts, was our first choice. Since no histochemical data were available on AlkP distribution and activity in fatty liver, we have first settled to investigate AlkP activity in the steatotic liver of fatty Zucker rats (fa/fa), using as controls lean Zucker (fa/+) and normal Wistar rats. The AlkP reaction in Wistar rats was in accordance with the existing data and, in particular, was present in bile canaliculi of hepatocytes in the periportal region and midzone, in the canals of Hering and in small bile ducts but not in large bile ducts. In lean ZR liver the AlkP reaction in Hering canals and small bile ducts was similar to Wistar rat liver but hepatocytes had lower canalicular activity and besides presented moderate basolateral reaction. The difference between lean Zucker and Wistar rats, both phenotypically normal animals, could be related to the fact that lean Zucker rats are genotypically heterozygous for a recessive mutated allele. In fatty liver, the activity in ductules and small bile ducts was unchanged, but most hepatocytes

    Understanding the dynamic nature of energy balance, and the interrelated and synergistic roles of diet and physical activity (PA) on body weight, will enable nutrition educators to be more effective in implementing obesity prevention education. Although most educators recognize that diet and PA are important for weight management, they may not fully understand their impact on energy flux and how diet alters energy expenditure and energy expenditure alters diet. Many nutrition educators have little training in exercise science; thus, they may not have the knowledge essential to understanding the benefits of PA for health or weight management beyond burning calories. This paper highlights the importance of advancing nutrition educators' understanding about PA, and its synergistic role with diet, and the value of incorporating a dynamic energy balance approach into obesity-prevention programs. Five key points are highlighted: (1) the concept of dynamic vs. static energy balance; (2) the role of PA in weight management; (3) the role of PA in appetite regulation; (4) the concept of energy flux; and (5) the integration of dynamic energy balance into obesity prevention programs. The rationale for the importance of understanding the physiological relationship between PA and diet for effective obesity prevention programming is also reviewed.

    Class B GPCRs can activate multiple signalling effectors with the potential to exhibit biased agonism in response to ligand stimulation. Previously, we highlighted key TM domain polar amino acids that were crucial for the function of the GLP-1 receptor, a key therapeutic target for diabetes and obesity. Using a combination of mutagenesis, pharmacological characterisation, mathematical and computational molecular modelling, this study identifies additional highly conserved polar residues located towards the TM helical boundaries of Class B GPCRs that are important for GLP-1 receptor stability and/or controlling signalling specificity and biased agonism. This includes (i) three positively charged residues (R3.30 227 , K4.64 288 , R5.40 310 ) located at the extracellular boundaries of TMs 3, 4 and 5 that are predicted in molecular models to stabilise extracellular loop 2, a crucial domain for ligand affinity and receptor activation; (ii) a predicted hydrogen bond network between residues located in TMs 2 (R2.46 176 ), 6 (R6.37 348 ) and 7 (N7.61 406 and E7.63 408 ) at the cytoplasmic face of the receptor that is important for stabilising the inactive receptor and directing signalling specificity, (iii) residues at the bottom of TM 5 (R5.56 326 ) and TM6 (K6.35 346 and K6.40 351 ) that are crucial for receptor activation and downstream signalling; (iv) residues predicted to be involved in stabilisation of TM4 (N2.52 182 and Y3.52 250 ) that also influence cell signalling. Collectively, this work expands our understanding of peptide-mediated signalling by the GLP-1 receptor. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

    Scientific studies which directly impact the larger society require an engagement between the scientists and the larger public. With respect to research on climate change, many third-party groups report on scientific findings and thereby serve as an intermediary between the scientist and the public. In many cases, the third-party reporting misinterprets the findings and conveys inaccurate information to the media and the public. To remedy this, many scientists are now taking a more active role in conveying their work directly to interested parties. In addition, some scientists are taking the further step of engaging with the general public to answer basic questions related to climate change - even on sub-topics which are unrelated to scientists' own research. Nevertheless, many scientists are reluctant to engage the general public or the media. The reasons for scientific reticence are varied but most commonly are related to fear of public engagement, concern about the time required to properly engage the public, or concerns about the impact to their professional reputations. However, for those scientists who are successful, these engagement activities provide many benefits. Scientists can increase the impact of their work, and they can help society make informed choices on significant issues, such as mitigating global warming. Here we provide some concrete steps that scientists can take to ensure that their public engagement is successful. These steps include: (1) cultivating relationships with reporters, (2) crafting clear, easy to understand messages that summarize their work, (3) relating science to everyday experiences, and (4) constructing arguments which appeal to a wide-ranging audience. With these steps, we show that scientists can efficiently deal with concerns that would otherwise inhibit their public engagement. Various resources will be provided that allow scientists to continue work on these key steps.

  14. Comparative discussion of the activated sludge and packed bed techniques in biological sewage water cleaning; Vergleichende Betrachtung von Belebungs- und Festbettverfahren fuer die biologische Abwasserreinigung

    It is reasonable to state that, given proper planning, erection and careful operation, both activated sludge plants and packed bed reactors with a biofilm are capable of meeting extremely high demands on the quality of the effluent. What was to be shown is the fact that operating behaviour and demands on measurement and control techniques differ considerably. Rating depends on different criteria, according to the technique chosen, and also cost calculation is largely determined in each case by special local conditions. All this makes it difficult to compare solutions with one another or to transfer experience gathered in one plant to another application. So the choice of the best possible method in a given case remains an interesting task.- One must try to make as objective a comparison as possible of different solutions according to the relevant criteria, beyond what is quantifiable merely in terms of finance.- Any decision taken on the basis of such a comparison is bound to reflect also the values that the decision-makers hold. But it should always be possible when taking decisions about processes to leave ideology out of consideration. (orig.)

    Full Text Available This article deals with the analysis of the language used in class by: (1 indicating the relevance of this type of analysis in the context of current research questions about the relations between language and education, (2 the analysis of the selected school classes and (3 by presenting methodological characteristics and possible research achievements of this form of analysis. Class language is here seen as one of school languages, and an item for the analysis of teaching and authentic evaluative information about education. Our research comprised the analyses of six classes in Belgrade elementary schools. The aim of the research was to identify and describe the language of the selected classes and to analyse the obtained information in the view of furthering language learning and learning by the use of language. Selected were three lessons in the first and three in the final classes, and planned so that pupils could be the main speakers (lesson repetition and elaboration. The analyses of the teaching contents were done, and the results showed that, compared to pupils, teachers do a major part of talking, that pupils usually give one word or short answers, that they communicate within uniform speech models and have no opportunity to develop a sense of ownership of the language of the lesson which is a precondition for further language learning and using language for school learning. The results also indicate certain contradictions in the identified language practice, which we deem important for further systematic research of language use and learning in our schools.

    The positive energy projection operators, just described by Prof. Sucher, convert the sick Hamiltonian, H/sub DC/, into a more robust one which can support bound states. They are however still a subject of some controversy. Prof. Grant pointed out that existing computer codes produce remarkable accuracy in numerical calculations which start from H/sub DC/ (with no projection operators) and so he questioned whether these operators were indeed necessary. In response, it was pointed out by several people in the audience that the codes implicitly limit the Dirac-Hartee-Fock wave functions to a normalizable sub-space and that this operation can be described as a projection operator which has the effect of eliminating the negative energy states which are not normalizable. This operation is however, not any of the three projection operators described by Sucher and so the question arises as to the sensitivity of the results (for the energy and wave functions) to the particular projection operators which are used. This appears to be an open question

  18. Caution, Student Experience May Vary: Social Identities Impact a Student’s Experience in Peer Discussions

    In response to calls for implementing active learning in college-level science, technology, engineering, and mathematics courses, classrooms across the country are being transformed from instructor centered to student centered. In these active-learning classrooms, the dynamics among students becomes increasingly important for understanding student experiences. In this study, we focus on the role a student prefers to assume during peer discussions, and how this preferred role may vary given a student’s social identities. In addition we explore whether three hypothesized barriers to participation may help explain participation difference in the classroom. These barriers are 1) students are excluded from the discussion by actions of their groupmates; 2) students are anxious about participating in peer discussion; and 3) students do not see value in peer discussions. Our results indicate that self-reported preferred roles in peer discussions can be predicted by student gender, race/ethnicity, and nationality. In addition, we found evidence for all three barriers, although some barriers were more salient for certain students than others. We encourage instructors to consider structuring their in-class activities in ways that promote equity, which may require more purposeful attention to alleviating the current differential student experiences with peer discussions.

    Full Text Available Walking, more specifically gait, is an essential component of daily living. Walking is a very different activity for individuals with a Body Mass Index (BMI of 40 or more (Class III obesity compared with those who are overweight or obese with a BMI between 26–35. Yet all obesity weight classes receive the same physical activity guidelines and recommendations. This observational study examined the components of function and disability in a group with Class III obesity and a group that is overweight or has Class I obesity. Significant differences were found between the groups in the areas of gait, body size, health condition, and activity capacity and participation. The Timed Up and Go test, gait velocity, hip circumference, and stance width appear to be most predictive of activity capacity as observed during gait assessment. The findings indicate that Class III-related gait is pathologic and not a normal adaptation.

    People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses' discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.

    Objective. To implement a learner-led, discussion-based course aimed at exposing second-year pharmacy learners to the study of emerging infectious diseases from a global health perspective and to assess the role and importance of pharmacists in the management of disease outbreaks. Design. Learners examined literature pertinent to an emerging infectious disease in a 3-credit, discussion-based course and participated in peer discussion led by a designated learner. Instructional materials included journal articles, audio-visual presentations, documentaries, book chapters, movies, newspaper/magazine articles, and other materials. Learning outcomes were measured based on the ability of learners to perform critical thinking and analysis, communicate with their peers, and participate in class discussions. Assessment. The course was offered to 2 consecutive cohorts consisting of 14 and 16 learners, respectively. Overall, every learner in the first cohort achieved a final grade of A for the course. In the second cohort, the overall grade distribution consisted of grades of A, B, and C for the course. Learner evaluations indicated that the active-learning, discussion-based environment significantly enhanced interest in the topic and overall performance in the course. Conclusion. The elective course on emerging infectious diseases provided in-depth exposure to disease topics normally not encountered in the pharmacy curriculum. Learners found the material and format valuable, and the course enhanced their appreciation of infectious diseases, research methodology, critical thinking and analysis, and their roles as pharmacists.

    Full Text Available Participation in physical education classes is a complex issue; many factors lead students to participate in classroom activities in different ways. This research examines how the way to take part in the class is influenced by experiences outside of school. In this way, seeks to analyze how the actions and family discourses influence the different interests of girls and boys, such as the participation in physical activities outside of school. Also, examines the influence of the participating inside of the school, and how expectations and understandings of bodily practices for boys and girls influence different ways to participate in classes when comparing the male and female gender. For this, held semi-structured interviews and classroom observations into four groups of the eighth year of two public schools in the city of Campinas-SP. The notes of this research indicated that the experience and knowledge of the body and body practice outside of school have the big influence on the ways of participating in classes. The cultural environment of the students gave different experiences and understandings for boys and girls in the knowledge that circulate in physical education classes and contributed in different ways to participate in class.

    In December 2007, the Forum on Stakeholder Confidence discussed its theme entitled 'Link between research, development and demonstration (RD and D) and stakeholder confidence'. It was remarked that regulators need a technical demonstration to aid in evaluating the safety case. Local stakeholders appreciate the opportunity to visualise technological arrangements. In both cases, demonstration adds to confidence in the feasibility of solutions. Some believe there is an important role for analogues in communication with stakeholders, if handled with integrity. To explore and benchmark current practices, it was decided to hold a topical session at the 9. regular meeting of the FSC on 4 June 2008 regarding the use of analogues for confidence building. The session opened with an introductory presentation by the session rapporteur. This incorporated input provided for the purpose by FSC members in cooperation with their country's representative to the NEA RWMC 'Integration Group on the Safety Case'. Three speakers then presented the various uses of analogues by implementers, regulators and scientists to build their own confidence; a fourth speaker dealt with the experience of using natural analogues in public information. The presentations addressed the use of analogues in the field of geological disposal of high-level waste (HLW) and long-lived intermediate level (ILW-LL) radioactive waste. Then the FSC participants split into two working groups for discussion. The outcome of these discussions was reported in plenary on 6 June 2008 and it was agreed to publish proceedings of the session. The present summary, prepared by the session rapporteur with input from the NEA Secretariat, captures the main points heard in the course of the event. It combines data from the formal presentations and remarks made in discussion. The latter represent viewpoints expressed by a group whose primary focus is not natural analogues but rather stakeholder interests. The summary and viewpoints

    Agents building social systems are characterized by complex states, and interactions among individuals can align their opinions. The Axelrod model describes how local interactions can result in emergence of cultural domains. We propose two variants of the Axelrod model where local consensus is reached either by listening and accepting one of neighbors' opinion or two agents discuss their opinion and achieve an agreement with mixed opinions. We show that the local agreement rule affects the character of the transition between the single culture and the multiculture regimes.

    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

    Effective leadership can be defined in many ways and is an essential element of successful organisations; poor leadership can result in problems such as low staff morale, high staff turnover and reduced productivity. Effective leadership behaviours are well documented in the literature and various leadership models have been proposed that illustrate these behaviours. This discussion paper does not focus on any particular model. Instead it considers the 'Leadership Qualities Framework' which was developed specifically for use within the UK National Health Service. This framework draws upon a range of leadership models and as such it gives a broad indication of leadership behaviours. The framework comprises three components - 'personal qualities', 'setting direction' and 'delivering the service'. This paper commences with an argument as to why effective leadership is important in organisations generally, and specifically within healthcare organisations. Various examples of leadership are illustrated from within and outside the NHS in order to demonstrate effective leadership behaviours. The Leadership Qualities Framework is then examined, along with scenarios to illustrate effective leadership behaviours in context (i.e. within a healthcare organisation). Subsequent reflections on the scenarios aim to identify leadership behaviours that are explained within the framework. The final element of this paper draws on [limited] published evidence of where consultant radiographers have demonstrated effective leadership behaviours. In this section the published evidence is examined and reflected upon. At the end of the article we indicate additional reading for those who wish to further develop their theoretical and practical leadership skills

    The metal failure cases discussed by P. Gupton (Monsanto Chem. Co.) at a joint meeting of the American Society of Metals (ASM) and the National Association of Corrosion Engineers Calgary Section (Calgary 1978) include a high-temperature (1775/sup 0/-1800/sup 0/F) failure in an HK 40 outside heater tube in a synthesis gas steam-methane reformer, resulting in two major fissures caused by carbonization and oxide deposits with high carbon and lead contents due to the use of remelt scrap material with high lead content; separation of a support pad from a 30 in. pipeline due to corrosion caused by molybdenum-peroxide action; oxidation of a section of 180/sup 0/ U-bend in a thermal ethylene cracking furnace due to fluxing reaction of a high sodium and calcium feed which collected in the return bed; stress corrosion cracking of an austenitic stainless cracker tube from high temperature and electrolytic attack; and other cases of metal failure caused by weld quality problems, use of contaminated material and inadequate designs, processing, and fabrication.

  18. Emission trading: A discussion paper

    International Nuclear Information System (INIS)

    1992-05-01

    Emission trading is a market-based incentive program designed to control air emissions in which a cap is placed on the total quantity of pollutants allowed to be emitted in an airshed. Appropriate shares of this amount are allocated among participating emission sources, and participants can buy or sell their shares. Advantages of emission trading include its potential to achieve air emission targets at a lower cost than the traditional command and control approach, and its ability to accommodate economic growth without compromising environmental quality. A study was conducted to evaluate the potential use of emission trading programs to achieve emission reduction goals set for nitrogen oxides, volatile organic compounds (VOC), and sulfur oxides. Emission trading programs in the USA are reviewed and a set of factors important for the success of emission trading are identified. Key policy and design issues related to an emission trading program are identified, explained, and discussed. Administrative issues are then analyzed, such as legislative authority, monitoring and enforcement requirements, and trading between jurisdictions. A preliminary assessment of emission trading for control of NOx and VOC in the Lower Fraser Valley indicates that emission trading would be feasible, but legislative authority to implement such a program would have to be introduced

    2015-01-01

    Bruxism is commonly considered a detrimental motor activity, potentially causing overload of the stomatognathic structures. The etiology of bruxism is unclear, but the condition has been associated with stress, occlusal disorders, allergies and sleep positioning. Due to its nonspecific pathology, bruxism may be difficult to diagnose. Unfortunately, very little data exists on the subject of a cause-and-effect relationship of bruxism to the point that expert opinions and cautionary approaches are still considered the best available sources for suggesting good practice indicators. The present paper reviewed current concepts on bruxism, etiology, diagnosis and management, underlining its effects on dental structures in an attempt to provide clinically useful suggestions based on scientifically sound data.

    We did not have laptops or computer networks in schools in 1968, when I started teaching physics. When classroom computers became available, followed by the internet, I greeted them as great educational tools. I developed my own website in order to provide reference material and assignments for my students. I found that online assignments were more likely than traditional ones to be completed. I also had my own system making password-protected grades available online. The parents loved it. I began giving some tests online. However, there is a downside to laptop use in class.

    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.

  3. Safety, tolerability, and preliminary activity of CUDC-907, a first-in-class, oral, dual inhibitor of HDAC and PI3K, in patients with relapsed or refractory lymphoma or multiple myeloma: an open-label, dose-escalation, phase 1 trial.

    Treatment options for patients with relapsed or refractory lymphoma and multiple myeloma are limited. CUDC-907 is an oral, first-in-class, small molecule that is designed to inhibit both histone deacetylase (HDAC) and PI3K enzymes, which are members of common oncogenic pathways in haematological malignancies. We aimed to assess overall safety and preliminary activity in this dose-escalation study of CUDC-907 monotherapy in patients with relapsed or refractory lymphoma and multiple myeloma. This open-label, first-in-man, phase 1 trial recruited adult patients (aged ≥18 years) with lymphoma or multiple myeloma who were refractory to or had relapsed after two or more previous regimens, from four US cancer centres. CUDC-907 was orally administered in a standard 3 + 3 dose-escalation design at four different dosing schedules, to which participants were sequentially assigned as follows: once daily, intermittently (twice or three times weekly; simultaneous enrolment), and daily for 5 days followed by a 2-day break (5/2), in 21-day cycles. Dosing started at 30 mg for the once-daily schedule and 60 mg for other schedules, escalating in 30 mg increments. Patients continued to receive CUDC-907 until disease progression or until other treatment discontinuation criteria were met. The primary objective was to determine the maximum tolerated dose (MTD) and recommended phase 2 dose, assessed in patients who received at least 66% of cycle 1 doses without modification and those who had a dose-limiting toxicity (DLT) in cycle 1 irrespective of dose modification. We assessed safety in all patients who received at least one dose of study drug. This ongoing trial is registered at ClinicalTrials.gov, number NCT01742988. Between Jan 23, 2013, and July 27, 2015, we enrolled 44 patients, of whom ten were sequentially assigned to CUDC-907 once-daily (MTD 60 mg), 12 to twice-weekly (MTD 150 mg), 15 to three-times-weekly (MTD 150 mg), and seven to the 5/2 dosing schedule (MTD 60 mg). 37

    This executive summary addresses the activities associated with the National Transuranic (TRU) Program managed by the Carlsbad Area Office (CAO). The CAO programmatically reports to the Assistant Secretary for Environmental Management and receives administrative support through the Albuquerque Operations Office. The mission of the Carlsbad Area Office (CAO) is to protect human health and the environment by opening and operating the Waste Isolation Pilot Plant for site disposal of TRU waste and by establishing an effective system for management of TRU waste from generation to disposal. It includes personnel assigned to the CAO, the Waste Isolation Pilot Plant (WIPP) site operations, and other activities associated with the National TRU Program. The CAO develops and directs implementation of the program, while the DOE Headquarters establishes policy and guidelines. The CAO assesses compliance with the program guidance, as well as the commonality of activities and assumptions among all the sites. Since the development of the February 28, 1997, database used to develop this Discussion Draft, the opening of the WIPP facility for receipt of Contact Handled waste has been delayed from November 1997 to May 1998. This slippage is significant enough to require a change in the milestones and volumes included in the documents to be reviewed by our stakeholders. Changes have been incorporated into this Discussion Draft and its supporting Project Baseline Summaries (PBSs)

    For road safety improvement, comparing and benchmarking performance are widely advocated as the emerging and preferred approaches. However, there is currently no universally agreed upon approach for the process of road safety benchmarking, and performing the practice successfully is by no means easy. This is especially true for the two core activities of which: (1) developing a set of road safety performance indicators (SPIs) and combining them into a composite index; and (2) identifying a meaningful reference (best-in-class), one which has already obtained outstanding road safety practices. To this end, a scientific technique that can combine the multi-dimensional safety performance indicators (SPIs) into an overall index, and subsequently can identify the 'best-in-class' is urgently required. In this paper, the Entropy-embedded RSR (Rank-sum ratio), an innovative, scientific and systematic methodology is investigated with the aim of conducting the above two core tasks in an integrative and concise procedure, more specifically in a 'one-stop' way. Using a combination of results from other methods (e.g. the SUNflower approach) and other measures (e.g. Human Development Index) as a relevant reference, a given set of European countries are robustly ranked and grouped into several classes based on the composite Road Safety Index. Within each class the 'best-in-class' is then identified. By benchmarking road safety performance, the results serve to promote best practice, encourage the adoption of successful road safety strategies and measures and, more importantly, inspire the kind of political leadership needed to create a road transport system that maximizes safety.

    Numerous studies have demonstrated that environmental parameters affect bivalve immunomarkers. In the present study, we tested the hypothesis that clams (Venerupis philippinarum) collected in sites with different environmental conditions respond differently to experimental contaminant exposure. Clams were collected at two sites within the Lagoon of Venice that are influenced differently by both anthropogenic impact and natural conditions: Marghera, which is characterised by relatively high contamination levels and restricted clam fishing, and Chioggia, which is inside a licensed clam culture area that is characterised by lower contamination levels. Total haemocyte count, haemocyte diameter and volume, lysozyme activity in both haemocyte lysate and cell-free haemolymph, superoxide dismutase and catalase activities in gills and digestive glands were measured at time 0 (clam sampling time), after 7 days of acclimation in the laboratory and after 1, 3 and 7 days of copper exposure. Interestingly, statistical analyses (three-way ANOVA and Canonical Correlation Analysis) revealed persistent differences in the biological responses of clams from the two sampling sites before and after copper exposure. Conversely, the influence of copper on cellular and biochemical parameters was negligible. Overall, the results obtained indicated that animals with a different ecological history respond differently to experimental contaminant exposure. In addition, this study suggested that immunomarkers and other biomarkers might be used to determine the origin of fishing products. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Critical thinking is often considered an essential learning outcome of institutions in higher education. Previous work has proposed three pedagogical strategies to address this goal: more active, student-centered in-class instruction, assessments which contain higher-order cognitive questions, and greater alignment within a classroom (i.e., high agreement of the cognitive level of learning objectives, assessments, and in-class instruction). Our goals were to determine which of these factors, individually or the interactions therein, contributed most to improvements in university students' critical thinking. We assessed students' higher-order cognitive skills in introductory non-majors biology courses the first and last week of instruction. For each of the fifteen sections observed, we also measured the cognitive level of assessments and learning objectives, evaluated the learner-centeredness of each classroom, and calculated an alignment score for each class. The best model to explain improvements in students' high-order cognitive skills contained the measure of learner-centeredness of the class and pre-quiz scores as a covariate. The cognitive level of assessments, learning objectives, nor alignment explained improvements in students' critical thinking. In accordance with much of the current literature, our findings support that more student-centered classes had greater improvements in student learning. However, more research is needed to clarify the role of assessment and alignment in student learning.

    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.

    1991-01-01

    A panel discussion on the radiotracer development process opened with a question regarding the role of toxicological studies in the process of obtaining a physician-sponsored Investigational New Drug (IND) for a new radiopharmaceutical. Panel members were uniformly supportive of new radiotracer development, expressing their opinions that the regulatory hurdles were there but could be overcome. Several institutions are actively working with regulatory agencies to determine just what toxicology data are relevant to new radiopharmaceutical development in the PET field. The FDA is beginning to understand that the pharmacology of PET tracer doses may be completely different from what is usually important in drug trials. The second part of the panel discussion centered on the role, if any, of the pharmaceutical companies in new radiotracer development. It was pointed out that what the radiochemist is looking for in a radiopharmaceutical is different from what these companies are searching for in a therapeutic drug. Panel and audience members responded to the question: What would a pharmaceutical company gain from collaboration with radiopharmaceutical research laboratories? Several examples were given such as providing crucial data from humans rather than animals; determining individualized drug doses to maximize the therapeutic index of a new drug regimen; and replacing the large amounts of time and money currently invested by drug companies in the radiolabeling and evaluation of metabolites of new drugs

    Rana and Sharma (2017) dispute our tectonic interpretation mainly on the basis of what they believe (climate?). However, we welcome their comments, as this gives us a chance to highlight the ambiguity inherent in discriminating the climate-tectonic imprints in morphotectonic records that are prevalent in current research. We should note that the paper published by Kothyari et al. (2017) was reviewed by national/international reviewers. We would like to emphasize the fact that the paper does not rule out the role of climate. However, most importantly, it presents significant features and observations that collection/assemblage points toward the dominant role of tectonics in their shaping, and not solely climate, as postulated by Rana and Sharma (2017). The objective of this paper is to identify tectonic signatures (geomorphology) in a monsoon - dominated, tectonically active terrain like the North Almora Thrust (NAT). These faults are marked by previous workers based on field evidence such as folding and faulting of lithological units; presence of slickensides parallel to the fault; offset of NAT owing to a transverse fault; and offset of drainage, drainage basin analysis, strath terraces, fluviolacustrine terraces, development of scarp, narrow river course, and deeply incised valleys. However, we disagree with the comments raised by Rana and Sharma (2017), because they are highly skewed toward the climate school of thought, and did not perceive the setting as a collection of landforms. Instead, they attempted to view them in isolation. Because these comments are important, we will try to further our research incorporating issues related to isolation of climate and tectonics imprints in the immediate future. We would like to thank Rana and Sharma (2017) for raising some basic questions on our work as this gave us an excellent opportunity to summarize and present the dominance of various processes and related landforms as earlier reported by Kothyari et al. (2017). A

    Full Text Available In striving to attain a higher degree of in-class student engagement, and target a larger number of preferred student-learning styles, this case study describes a multimodal teaching approach. PowerPoint slides have gradually gained popularity over the more traditional chalk and talk lecture design. The student population in today’s age seeks more non-passive modes of information delivery. Numerous novel approaches to enhance active learning, such as flipped classroom and problem-based learning, have recently been explored. While working well for therapeutic and lab-based courses, these formats may not be best-suited for all basic science topics. The importance of basic science in a pharmacy curriculum is well emphasized in the 2016 ACPE Standards. To actively involve students in a pharmacology lecture on diuretics, a session was designed to combine the PowerPoint and chalk talk approaches. Students created 10 concept diagrams following an instructor, who explained each step in the process using a document camera. For visual learners, these diagrams provided a layered representation of the information, gradually increasing in complexity. For learners with a preference for the reading learning style, the information was also available in corresponding PowerPoint slides. Scores from pre- and post-session quizzes indicated a high level of concept understanding and recall (median 1 [IQR 0 – 2] vs 4 [IQR 3 – 5]; p<0.001. The student perception survey data reported higher in-class attention levels (76%, an appreciation for the utility of self-created concept diagrams (88%, and a call for additional sessions being presented in this format (73%. Targeting a variety of student learning styles by using the active development of concept diagrams, in addition to traditional PowerPoint slides, can promote student engagement and enhance content understanding.   Type: Case Study

    Vic Montemayor - No one has been more passionate about improving the quality and effectiveness of the teaching of Medical Physics than Bill Hendee. It was in August of 2008 that the first AAPM Workshop on Becoming a Better Teacher of Medical Physics was held, organized and run by Bill Hendee. This was followed up in July of 2010 with a summer school on the same topic, again organized by Bill. There has been continued interest in alternate approaches to teaching medical physics since those initial gatherings. The momentum established by these workshops is made clear each year in the annual Innovation in Medical Physics Education session, which highlights work being done in all forms of medical physics education, from one-on-one residencies or classroom presentations to large-scale program revisions and on-line resources for international audiences. This symposium, presented on behalf of the Education Council, highlights the work of three finalists from past Innovation in Education sessions. Each will be presenting their approaches to and innovations in teaching medical physics. It is hoped that audience members interested in trying something new in their teaching of medical physics will find some of these ideas and approaches readily applicable to their own classrooms. Rebecca Howell - The presentation will discuss ways to maximize classroom learning, i.e., increasing the amount of material covered while also enhancing students’ understanding of the broader implications of the course topics. Specifically, the presentation will focus on two teaching methodologies, project based learning and flip learning. These teaching methods will be illustrated using an example of graduate medical physics course where both are used in conjunction with traditional lectures. Additionally, the presentation will focus on our experience implementing these methods including challenges that were overcome.

    It is the ultimate goal of the intended REACH process (Registration, Evaluation and Authorization of Chemicals) of the European Union to identify substances of hazardous properties and to evaluate the risks of human and environmental exposure. During the last few months there has been a controversial discussion as to what extent in vitro studies and consideration of structure activity relationship provide sufficient information to waive repeated exposure studies. Industry as well as certain regulatory agencies or NGOs support this approach and propose that repeated dose studies may only be required beyond 100 t/a. From a toxicological point of view it has to be stressed that this discussion primarily considers the cost reduction and protection of animals, whereas protection of human health and the environment are secondary. In vitro studies only allow identification of specific hazardous properties which can be detected by the specific test system. Moreover, appropriate information on the dose response of adverse effects, identification of thresholds and NOELs that are essential for risk characterization cannot be obtained from these studies. Consequently, identification of all relevant hazardous properties and endpoints of adverse effects can only be determined in the intact animal by repeated dose studies such as 28-day or 90-day studies. In the absence of such information the hazard identification is incomplete and there is no basis for appropriate risk assessment of human exposure. Thus, any waiving of repeated dose studies in animals bears the probability of unforeseen effects in case of acute or continuous human exposure. From this the undersigning European Toxicologists conclude: 1. The intention of REACH is to identify hazardous properties in order that a reliable risk assessment can be made and measures taken to deal with chemicals posing a significant risk. 2. The recent debate has centered on ways in which the well established in vivo methods for risk

  12. Gene Expression in Class 2 Integrons Is SOS-Independent and Involves Two Pc Promoters.

    Integrons are powerful bacterial genetic elements that permit the expression and dissemination of antibiotic-resistance gene cassettes. They contain a promoter Pc that allows the expression of gene cassettes captured through site-specific recombination catalyzed by IntI, the integron-encoded integrase. Class 1 and 2 integrons are found in both clinical and environmental settings. The regulation of intI and of Pc promoters has been extensively studied in class 1 integrons and the regulatory role of the SOS response on intI expression has been shown. Here we investigated class 2 integrons. We characterized the P intI2 promoter and showed that intI2 expression is not regulated via the SOS response. We also showed that, unlike class 1 integrons, class 2 integrons possess not one but two active Pc promoters that are located within the attI2 region that seem to contribute equally to gene cassette expression. Class 2 integrons mostly encode an inactive truncated integrase, but the rare class 2 integrons that encode an active integrase are associated with less efficient Pc2 promoter variants. We propose an evolutionary model for class 2 integrons in which the absence of repression of the integrase gene expression led to mutations resulting in either inactive integrase or Pc variants of weaker activity, thereby reducing the potential fitness cost of these integrons.

    2010-03-01

    Full Text Available This study focuses on the characterization of graphocentrism in microculture. We aim to describe, based on literacy studies, the presence of written language in the life of socially and historically situated subjects, thematizing the axiological capital of less favored socioeconomic contexts. Subjects are children undergoing schooling process, living in a district of Florianópolis, Santa Catarina, Brazil. Discussions on the theme are based on Barton (1994, Barton, Hamilton and Ivanic (2000, Heath (1982, and Street (1994, 2003. Looking at literacy from a sociocultural perspective implies understanding that subjects deal with written language in their daily life in different ways. It seems that school tends to teach subject matters defined beforehand, and this hampers the dialog with different social practices played by students who come from family environments with different schooling levels. This study is inserted in a project whose focus is the defense of a more sensible look of school concerning the different realities which constitute school itself, regarding the teaching of written language. The present research aims to answer the following questions: How can we configure the microculture (family, school, church, neighborhood – more or less graphocentric – where children attending 1st to 5th grade live, in an economically less privileged community of Florianópolis? How can we delineate the axiological capital regarding the mastering of written language by those children? What literacy events are more recurrent within that microculture? The data were collected by means of interviews, observations and field annotations, focusing on the visible elements of literacy events, similarly to what has been done by Hamiton (2000, such as participants, environments, artifacts, and activities. On the hand, the non-visible constituents of literacy practices, such as hidden participants, domain, resources, and routines, were observed during

    2014-01-01

    Background Efforts are made to enhance in-class learner engagement because it stimulates and enhances learning. However, it is not easy to quantify learner engagement. This study aimed to develop and validate an observation tool for instructor and student behaviors to determine and compare in-class learner engagement levels in four different class types delivered by the same instructor. Methods Observer pairs observed instructor and student behaviors during lectures in large class (LLC, n=2) with third-year medical students, lectures in small class (LSC, n=6) and case-based teaching sessions (CBT, n=4) with fifth-year students, and problem-based learning (PBL) sessions (~7 hours) with second-year students. The observation tool was a revised form of STROBE, an instrument for recording behaviors of an instructor and four randomly selected students as snapshots for 5-min cycles. Instructor and student behaviors were scored 1–5 on this tool named ‘in-class engagement measure (IEM)’. The IEM scores were parallel to the degree of behavior's contribution to active student engagement, so higher scores were associated with more in-class learner engagement. Additionally, the number of questions asked by the instructor and students were recorded. A total of 203 5-min observations were performed (LLC 20, LSC 85, CBT 50, and PBL 48). Results Interobserver agreement on instructor and student behaviors was 93.7% (κ=0.87) and 80.6% (κ=0.71), respectively. Higher median IEM scores were found in student-centered and problem-oriented methods such as CBT and PBL. A moderate correlation was found between instructor and student behaviors (r=0.689). Conclusions This study provides some evidence for validity of the IEM scores as a measure of student engagement in different class types. PMID:25308966

    Session 1 provided the opportunity to be informed of the Japanese institutional scene on geologic disposal as well as to acquaint the Japanese dignitaries and workshop participants with the RWMC Regulators' Forum, the challenges we face and the aims of the workshop. A lecture on accomplishments and issues in long-term safety regulation prepared discussions during the workshop. Session 2 - Fundamental Concepts and Evolution of International Guidance: One important point is that the use of language in this subject is not conducive to easy understanding by the public, certainly, and perhaps even by others. We need to consider how it might be made more accessible for the purpose of public involvement and regulatory dialogue. This might open the way to creating a readily comprehensible long-term objective for geological disposal that is consistent with the objectives for protecting society from the potential consequences of other activities with long-lived implications. The goal of the following presentations was to give an overall picture on these questions. Session 3 - Establishing Regulatory Criteria that Account for the Inherent Difficulties Associated with the Long-time Frames for Protection: Even though there have been significant developments in recent years and experience feedback from a number of ongoing geological disposal projects, international guidance remains rather difficult to understand and apply. The recent work from the RWMC-RF on long-term safety criteria for geological for geological disposal also shows that there are important differences between national criteria as well as differences in regulatory approach. It has emerged that we have no common basis for setting criteria as between different NEA countries and that the process of setting criteria is not readily explicable to the general public. Furthermore we are required, for the purposes of the international Joint Convention on the Safe Management of Spent Fuel and Radioactive Waste, to protect

    Online discussion has become one of the important strategies for the teacher to teach the students to think critically when conveying their ideas and become more proactive and creative. In this paper, padlet online discussion communication was conducted to examine its effectiveness in enhancing critical thinking. In this study, there are two types of critical thinking: macro and micro critical thinking. A total of 70 Universiti Utara Malaysia Management Foundation Programme students involved in this experimental research design. The students in treatment class are divided to few groups. Every group uses padlet online discussion to discuss the topic given. All the group members discuss and write their ideas in padlet. Ideas that are posted in padlet will be displayed in front of the class so that the entire group in the treatment class could see the given ideas. Paul's (1993) model was used to analyze student's macro and micro critical thinking in padlet online discussion and communication. The finding shows that students who used padlet online discussion backchannel communication have greater macro and micro critical thinking level than students who do not use online discussion.

    To compare the craniofacial growth characteristics of untreated subjects with Class II division 1 malocclusion with those of subjects with normal (Class I) occlusion from the prepubertal through the postpubertal stages of development. The Class II division 1 sample consisted of 17 subjects (11 boys and six girls). The Class I sample also consisted of 17 subjects (13 boys and four girls). Three craniofacial regions (cranial base, maxilla, and mandible) were analyzed on the lateral cephalograms of the subjects in both groups by means of thin-plate spline analysis at T1 (prepubertal) and T2 (postpubertal). Both cross-sectional and longitudinal comparisons were performed on both size and shape differences between the two groups. The results showed an increased cranial base angulation as a morphological feature of Class II malocclusion at the prepubertal developmental phase. Maxillary changes in either shape or size were not significant. Subjects with Class II malocclusion exhibited a significant deficiency in the size of the mandible at the completion of active craniofacial growth as compared with Class I subjects. A significant deficiency in the size of the mandible became apparent in Class II subjects during the circumpubertal period and it was still present at the completion of active craniofacial growth.

  11. Using Pre-Assessment and In-Class Questions to Change Student Understanding of Molecular Movements

    2017-05-01

    Full Text Available Understanding how different types of molecules move through cell membranes is a fundamental part of cell biology. To identify and address student misconceptions surrounding molecular movement through cell membranes, we surveyed student understanding on this topic using pre-class questions, in-class clicker questions, and subsequent exam questions in a large introductory biology course. Common misconceptions identified in student responses to the pre-class assessment questions were used to generate distractors for clicker questions. Two-tier diagnostic clicker questions were used to probe incoming common student misconceptions (first tier and their reasoning (second tier. Two subsequent lectures with assessment clicker questions were used to help students construct a new framework to understand molecular movement through cell membranes. Comparison of pre-assessment and post-assessment (exam performance showed dramatic improvement in students’ understanding of molecular movement: student answers to exam questions were 74.6% correct with correct reasoning while only 1.3% of the student answers were correct with correct reasoning on the pre-class assessment. Our results show that students’ conceptual understanding of molecular movement through cell membranes progressively increases through discussions of a series of clicker questions and suggest that this clicker-based teaching strategy was highly effective in correcting common student misconceptions on this topic.

  12. 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

    [Joint Press Release by the Government of the Republic of Chile and the European Southern Observatory. The text is issued simultaneously in Santiago de Chile (in Spanish) and at the ESO Headquarters in Garching (in English).] Today, Tuesday, 18 April 1995, at the ESO Headquarters in Garching (Germany), Mr. Roberto Cifuentes, Plenipotentiary Ambassador representing the Government of the Republic of Chile, and the Director General of the European Southern Observatory, Professor Riccardo Giacconi, have signed a Supplementary, Interpretative and Amending Agreement to the Convention of 6 November 1963 which governs the relations between Chile and this International Organisation. This Agreement which in practice signifies a widening and strengthening of the cooperative relations between the Organisation and the Chilean scientific community will hereafter be submitted for ratification by the National Congress of the Republic of Chile (the Parliament) and by the ESO Council. According to the Agreement signed today, Chilean astronomers will have privileged access within up to 10 percent observing time on all present and future ESO telescopes in Chile. Moreover, ESO accepts to incorporate into its labour regulations for Chilean personnel concepts like freedom of association and collective bargaining. This signing of the Supplementary, Interpretative and Amending Agreement to the original Convention of 1963 follows after months of constructive dialogue between the parties. It constitutes an important step towards a solution of some of the pending points on the current agenda for discussions between the Government of Chile and ESO. Among the issues still pending, ESO has informed the Government of Chile that respect for its immunities by the Chilean State is of vital importance for the continuation of the construction of the world's largest telescope at Paranal, as well as the continued presence of the Organisation in Chile.

    Full Text Available The purpose of this case study was to investigate online discussion as a means to promote critical reflection. The study was conducted during a semester-long graduate course on issues related to literacy instructional strategies. The participants in the study were four reading education candidates. During the semester they participated in online discussion about course readings and reflected on their own teaching experiences. The data sources were the online discussion postings, responses to questionnaires, and interviews. The results suggest that technology-mediated discussion strengthens the learning community, facilitates sharing of professional experience among participants, and enhances teacher reflection. The results also point to the multi-faceted nature of teacher reflection.

    Till, J E

    1995-09-01

    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.

  20. Cyclic subgroups in class groups of real quadratic fields

    International Nuclear Information System (INIS)

    Washington, L.C.; Zhang Xianke.

    1994-01-01

    While examining the class numbers of the real quadratic field Q(√n 2 + 3n + 9), we observed that the class number is often a multiple of 3. There is a simple explanation for this, namely -27 = (2n + 3) 2 - 4(n 2 + 3n + 9), so the cubes of the prime ideals above 3 are principal. If the prime ideals themselves are non-principal then 3 must divide the class number. In the present paper, we study this idea from a couple different directions. In the first section we present a criterion that allows us to show that the ideal class group of a real quadratic field has a cyclic subgroup of a given order n. We then give several families of fields to which this criterion applies, hence in which the ideal class groups contain elements of order n. In the second section, we discuss the situation where there is only a potential element of order p (=an odd prime) in the class group, such as the situation described above. We present a modification of the Cohen-Lenstra heuristics for the probability that in this situation the class number is actually a multiple of p. We also extend this idea to predict how often the potential element of order p is actually non-trivial. Both of these predictions agree fairly well with the numerical data. (author). 14 refs, 2 tabs

  1. In-Class Cycling to Augment College Student Academic Performance and Reduce Physical Inactivity: Results from an RCT

    Full Text Available Most college students sit 14 hours per week on average, excluding sedentary study time. Researchers observing workplace and elementary school settings with active workstations to combat sedentary behavior have shown enhanced cognition without distraction. Until now, incorporating active workstations in college classroom settings remained relatively unexplored. This study’s purpose was to assess academic performance using in-class stationary cycle desks during a semester-long lecture course. Twenty-one college students (19–24 years enrolled in a lecture course volunteered and were split into traditional sit (SIT and stationary cycle (CYC groups randomly, matched on a calculated factor equal to a physical activity (PA score (0–680 multiplied by grade point average (GPA; 4.0 scale. CYC pedaled a prescribed rate of perceived exertion (RPE of less than 2 out of 10 during a 50-min lecture, 3 × week for 12 weeks. CYC averaged 42 min, 7.9 miles, and 1.7 RPE during class throughout the semester. No significant differences (p > 0.05 were observed between CYC and SIT on in-class test scores or overall course grades. Although statistically insignificant, CYC had higher mean test scores and overall course grades vs. SIT (i.e., B+ vs. B, respectively. Low intensity cycling during a college lecture course maintained student academic performance and possibly reduced weekly sedentary behavior time.

  2. [Computer mediated discussion and attitude polarization].

    Shiraishi, Takashi; Endo, Kimihisa; Yoshida, Fujio

    2002-10-01

    This study examined the hypothesis that computer mediated discussions lead to more extreme decisions than face-to-face (FTF) meeting. Kiesler, Siegel, & McGuire (1984) claimed that computer mediated communication (CMC) tended to be relatively uninhibited, as seen in 'flaming', and that group decisions under CMC using Choice Dilemma Questionnaire tended to be more extreme and riskier than FTF meetings. However, for the same reason, CMC discussions on controversial social issues for which participants initially hold strongly opposing views, might be less likely to reach a consensus, and no polarization should occur. Fifteen 4-member groups discussed a controversial social issue under one of three conditions: FTF, CMC, and partition. After discussion, participants rated their position as a group on a 9-point bipolar scale ranging from strong disagreement to strong agreement. A stronger polarization effect was observed for FTF groups than those where members were separated with partitions. However, no extreme shift from their original, individual positions was found for CMC participants. There results were discussed in terms of 'expertise and status equalization' and 'absence of social context cues' under CMC.

    Discussing the theological beliefs that ground Catholic moral principles can make some people uncomfortable, even while others will appreciate it. But these reactions will sometimes be revealed not as the emotions they are, but as objections to the relative independence or dependence of morality on foundational beliefs. In the end, context should dictate whether one displays the theological beliefs that ground Catholic moral principles.

  20. Conflicting perspectives compromising discussions on cardiopulmonary resuscitation.

    LENUS (Irish Health Repository)

    Groarke, J

    2010-09-01

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    2017-09-01

    The aim of this study was to examine the potential of a self-designed Facebook page on Neuroscience, to supplement in-class teaching as a mode of blended learning. Posts were split into multiple choice questions (MCQs), general interest articles, neuroscience-related external links and resources, and lecture notes and PowerPoint presentations. The study was divided into three distinct phases: before, during, and after the Neuroscience block. Student responses were evaluated via a self-developed questionnaire. Grades achieved by students undertaking the block in 2015 and 2014 were recorded, as were the grades achieved by the same cohort in concurrent blocks in the same year of study. Results showed that ~80% of students reported that use of the page enhanced their overall subject knowledge and exam preparation. Highest page activity occurred during the Neuroscience block. Peak activity occurred directly before summative assessments, with MCQ posts having the highest impact. The cohort of students with access to the Facebook page achieved better grades in the block compared with the previous cohort, despite similar average performance in other subjects. We demonstrate the utility of Facebook as a powerful tool for undergraduate education, supplementing in-class teaching, and assisting in exam preparation, potentially increasing average student performance.

    2004-12-01

    Full Text Available The search for understanding the interactive processes of complex dynamic has motivated relative researches on the teacher's speech and its impact in the conduction of activities that are developed in the classroom. This work discusses the results of an activity of physics knowledge developed by three different student groups of three different primary schools. We focus our analysis about the way teachers organized their speeches to conduct that didactic activity and how those speeches influenced in the students argumentative construction. The results show that the teacher's speech, that mixes different discursive resources, contributes more significantly to the process of argument construction by the students.

    The aim of the present paper is to summarise current and future applications of dietary assessment technologies in nutrition surveys in developed countries. It includes the discussion of key points and highlights of subsequent developments from a panel discussion to address strengths and weaknesses of traditional dietary assessment methods (food records, FFQ, 24 h recalls, diet history with interviewer-assisted data collection) v. new technology-based dietary assessment methods (web-based and mobile device applications). The panel discussion 'Traditional methods v. new technologies: dilemmas for dietary assessment in population surveys', was held at the 9th International Conference on Diet and Activity Methods (ICDAM9), Brisbane, September 2015. Despite respondent and researcher burden, traditional methods have been most commonly used in nutrition surveys. However, dietary assessment technologies offer potential advantages including faster data processing and better data quality. This is a fast-moving field and there is evidence of increasing demand for the use of new technologies amongst the general public and researchers. There is a need for research and investment to support efforts being made to facilitate the inclusion of new technologies for rapid, accurate and representative data.

  1. Axial nonimaging characteristics of imaging lenses: discussion.

    Science.gov (United States)

    Siew, Ronian

    2016-05-01

    At observation planes away from the image plane, an imaging lens is a nonimaging optic. We examine the variation of axial irradiance with distance in image space and highlight the following little-known observation for discussion: On a per-unit-area basis, the position of the highest concentration in image space is generally not at the focal plane. This characteristic is contrary to common experience, and it offers an additional degree of freedom for the design of detection systems. Additionally, it would also apply to lenses with negative refractive index. The position of peak concentration and its irradiance is dependent upon the location and irradiance of the image. As such, this discussion also includes a close examination of expressions for image irradiance and explains how they are related to irradiance calculations beyond the image plane. This study is restricted to rotationally symmetric refractive imaging systems with incoherent extended Lambertian sources.

The CNSC is well situated to engage with proponents of SMR reactors in design reviews or licensing discussions. A risk-informed (graded) approach is possible in many instances for reactors but it is not a relaxation of requirements. The vendor design review process helps reduce regulatory risks by encouraging early engagement.

  9. Round table discussion during session 1

    2004-01-01

    The round table discussions of the first session of the Belgium Workshop addressed the following questions: - Accepting or refusing a person, an institution or a grouping as a legitimate Stakeholder who makes the decision and how? - How are the local partnerships built and organised? - How to obtain community support for the partnership's legitimate decisions/findings? - Experience teaches that no decision is reached solely by formal and legal processes. What role do informal processes play? - How can the informal procedures be accepted? Do they need to be made explicit? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. After the discussion, each table's findings were reported to the plenary. Most of the discussion concerned the local partnerships. Important findings were that the statutes for the partnerships were developed by the partnerships themselves and there were no legally binding rules handed down by the federal level. The partnerships are part of an informal process. A legally binding participation (i.e. within the EIA) will be initiated at a later stage. As the partnerships function outside of the formal legal procedure, they can function in a more flexible way. It was noted that the partnerships make recommendations, but it is not clear what the government will do with these recommendations. It was also argued that the process may cause conflicts between neighboring communities. As in other contexts visited by the FSC, the importance of the right of veto of the community was stressed, although this may cause a conflict between technical suitability and social acceptance. Access of the community to the local partnership is necessary. Finally it was accepted that time is needed to explain the recommendations to the broader community before any decisions are taken.

    The round table discussions of the second session of the FSC Belgium Workshop addressed the following questions: - Do local stakeholders have, internally or externally, all the expertise they need in order to address the issues raised by radioactive waste management projects? - Do institutional stakeholders have all the expertise they need to take local impacts into account? - What kinds of expert input are sought and attained by the different stakeholders? - Were any formal methods used to aid local partnerships perform technology assessments? Or other types of assessment? - How to maintain the knowledge and expertise achieved by the stakeholders? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. As in Session I, most of the round table discussion focussed specifically on the experience of the local partnerships. Many insights were shared about the nature and role of expertise in complex decision making. They are summarised below, on the basis of the feedback provided to the plenary by each round table. Some of these insights can be generalised to other contexts. All in all, a profile emerged of the local partnerships as a unique and effective tool to deal with knowledge issues in managing risk.

    2007-01-01

    Full Text Available In this concise review we discuss some of the complex edges of the concept of death that arose after the notorious advances in science and medicine over the last 50 years, in which the classical cardio-pulmonary criteria have led to the neurological criteria of death. New complicated questions like the definition of death and the operational criteria for diagnosing it have arisen and we think that they are far from being adequately and satisfactorily solved. A number of important issues -like the reliability and differences between cardio-pulmonary versus brain based criteria of death, if death is an event or a process, the meaning of integration and irreversibility- have not yet received sufficient attention. Here we have approached the death problem from two (biological complex system perspectives: the organism level and the cellular-molecular level. We also discuss issues from a third systemic approach, that is, the entire society, thus involving legal, religious, bioethical and political aspects of death. Our aim is to integrate new perspectives in order to promote further discussion on these critical yet frequently neglected issues

    O'Keefe, J. A.; Barkatt, A.; Glass, B. P.; Alterescu, S.

    J. J. Crovisier and J. Honnorez [1988] discuss an article by W. W. Maggs, “Mg May Protect Waste Under Glass” [Maggs, 1988] summarizing work by A. Barkatt (Catholic University, Washington, D.C.), B. P. Glass (University of Delaware, Newark), and S. Alterescu and J. A. O'Keefe (NASA/GSFC, Greenbelt, Md.). We found that seawater is orders of magnitude less corrosive t h an fresh water in attacking tektite glass; traced the protective effect to the presence of magnesium, at a level of about 1.3 g/L in seawater; and suggested that the effect might be useful in protecting nuclear waste glasses from corrosion.Crovisier and Honnorez first make the point that the rate of corrosion of glass is, in principle, a function of the ratio of surface area 5 to the effective volume V. This concept, which is usually discussed in American literature under the name of S/V effects, is discussed by Crovisier and Honnorez in terms of the “permeability of the environment.” These effects have been carefully considered throughout our work (see, for example, Barkatt et al. [19867rsqb;). It turns out that in the sea the effective S/V is so small that the effects referred to by Crovisier and Honnorez can be ignored.

    To describe oncology nurses' experiences discussing clinical trials with their patients, and to assess barriers to these discussions.
. A qualitative study designed to elicit narratives from oncology nurses. 
. Community- and academic-based oncology clinics throughout the United States.
. 33 oncology nurses involved in direct patient care in community-based and large hospital-based settings. The sample was drawn from members of the Oncology Nursing Society. 
. In-depth interviews were conducted and analyzed using a 
immersion/crystallization approach to identify themes and patterns. The analyses highlight specific issues, examples, and contexts that present challenges to clinical trial discussions with patients.
. Oncology nurses view their roles as patient educators and advocates to be inclusive of discussion of clinical trials. Barriers to such discussions include lack of knowledge and strategies for addressing patients' common misconceptions and uncertainty about the timing of discussions.
. These data indicate that enabling nurses to actively engage patients in discussions of clinical trials requires educational interventions to build self-efficacy and close knowledge gaps. 
. Oncology nurses can play a critical role in advancing cancer care by supporting patients in decision making about clinical trial participation. This will require training and education to build their knowledge, reduce barriers, and increase their self-efficacy to fulfill this responsibility in various clinical settings.

    The concept of risk, the methods for assessing risk and the acceptability of risk are discussed. The emphasis was laid on the three components for complete description of a risk: scenario, probability and consequence of an event. The disadvantages of the concept and presentation of risk used in some risk analysis were pointed out. The paper emphasized that it is necessary to explicitly consider the multi-dimensionality of risk in the assessment and management of risk. Several important factors influencing the acceptability of risk and the methodology for evaluating the acceptability of risk were also described

    The experts' discussion on reactor safety research deals with risk analysis, political realization, man and technics, as well as with the international state of affairs. Inspite of a controversy on individual issues and on the proportion of governmental and industrial involvment in reactor safety research, the continuation and intensification of corresponding research work is said to be necessary. Several participants demanded to consider possible 'conventional accidents' as well as a stronger financial commitment by the industry in this sector. The ratio 'man and technics' being an interface decisive for the proper functioning or failure of complex technical systems requires even more research work to be done. (GL) [de

  8. Brain plasticity, memory, and aging: a discussion

    Energy Technology Data Exchange (ETDEWEB)

    Bennett, E.L.; Rosenzweig, M.R.

    1977-12-01

    It is generally assumed that memory faculties decline with age. A discussion of the relationship of memory and aging and the possibility of retarding the potential decline is hampered by the fact that no satisfactory explanation of memory is available in either molecular or anatomical terms. However, this lack of description of memory does not mean that there is a lack of suggested mechanisms for long-term memory storage. Present theories of memory usually include first, neurophysiological or electrical events, followed by a series of chemical events which ultimately lead to long-lasting anatomical changes in the brain. Evidence is increasing for the biochemical and anatomical plasticity of the nervous system and its importance in the normal functioning of the brain. Modification of this plasticity may be an important factor in senescence. This discussion reports experiments which indicate that protein synthesis and anatomical changes may be involved in long-term memory storage. Environmental influences can produce quantitative differences in brain anatomy and in behavior. In experimental animals, enriched environments lead to more complex anatomical patterns than do colony or impoverished environments. This raises fundamental questions about the adequacy of the isolated animal which is frequently being used as a model for aging research. A more important applied question is the role of social and intellectual stimulation in influencing aging of the human brain.

    Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4% female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend's reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents’ social and moral development. PMID:23666555

    2013-03-01

    The author introduces a special section of Psychological Bulletin devoted to the study of disgust. After discussing conflicts between its supposed role as a basic emotion and its more recently understood involvement in responding to moral transgressions, the author summarizes 3 articles contained in the special section. Widen and Russell (2013) present a developmental account of disgust highlighting the ages at which children experience, express, understand, verbalize, and recognize disgust. The article shows that disgust is present early but that recognition of disgust in others is considerably delayed. Chapman and Anderson (2013) review evidence pertaining to the question of whether genuine disgust is elicited by moral transgressions. Their review covers data from self-report, brain imaging, facial behavior, and implicit measures gathered from both experimental and correlational studies. They conclude that moral transgressions elicit genuine disgust. Russell and Giner-Sorolla (2013) ask what types of moral transgressions are most likely to elicit pure disgust. They find that moral transgressions involving body violations are more likely than others to elicit such disgust. Moreover, they suggest that disgust elicited by body violations is likely to be more resistant to modification by context, situation, and efforts at rationalization. Taken together, the reviews support the view that rudiments of disgust to physical objects are present early in life but later become adapted to social influence and new moral purposes. Social implications are discussed. © 2013 American Psychological Association

    The first two presentations were given by specialists in human science, and focused more on the ethical aspects of the funding for decommissioning. Some new aspects or approaches were presented, which allowed to highlight the egalitarian and utilitarian approaches of inter-generational equity. The different ethical principles led to conclude on the need of a democratic debate on the subject, and the need of ethical guidance at international level. Some other key points, like the preservation of competences, funding and resources, were also considered in the light of the inter-generational community. The session was concluded by a presentation on the application of the ethical principles for the funding. Session 2: Actual experience in funding. The various mechanisms for funding have been analyses on their principle, current practice and merits. Three main aspects were analysed: How funds are raised? How are the funds managed? How to disburse when needed? The actual experience in different countries showed different mechanisms and return of experience. Session 3: Uncertainties. In most large industrial projects (construction, civil works, aerospace...), the return of experience shows that overrun (in time and cost) is a rather general tendency. But it depends on the type of project, on the degree of innovation, etc. Some means to avoid these overrun were presented. In the case of D and D, the main uncertainties affecting funding can be found in: cost estimate, inflow of resources, management of resources, time factor: when will the costs occur? Moreover, these uncertainties sources can also be inter-linked. One of the conclusions from this analysis is that the existing uncertainties in funding are good reasons not to postpone decommissioning operations to a too distant future. Presentations on return of experience were presented by several countries. Plenary discussions: The plenary discussions allowed to tackle the different aspects presented during the day. Some

    2014-09-01

    Full Text Available Historical ethical dilemmas are a valuable tool in bioethics courses. However, garnering student interest in reading and discussing the assigned cases in the classroom can be challenging. In an effort to actively engage undergraduate and graduate students in an Ethical Issues in Biotechnology course, an activity was developed to encourage reflection on a classical ethical dilemma between a patient, St. Martin, and his employer/caretaker, Beaumont. Two different texts were used to analyze the ethical ramifications of this relationship: a chapter in a popular press book and a short perspective in a medical journal. Participants read the book chapter for homework and discussed it in class. This easy read highlights the fundamental ethical issues in the relationship between two men. Students were then provided with a second text focusing on the scientific accomplishments achieved through Beaumont's experimentation on St. Martin. A structured worksheet prompted participants to reflect on their feelings after reading each text and create a concept map depicting the dilemma. Student-generated concept maps and written reflections indicate participants were able to list the ethical issues, analyze the situation, and evaluate the information provided. This activity not only encouraged higher-level thinking and reflection, it also mirrored the course's structured approach of using concept mapping and reflection to dissect ethical dilemmas.

  14. Maintaining Live Discussion in Two-Stage Open Peer Review

    Science.gov (United States)

    Sandewall, Erik

    2011-01-01

    Open peer review has been proposed for a number of reasons, in particular, for increasing the transparency of the article selection process for a journal, and for obtaining a broader basis for feedback to the authors and for the acceptance decision. The review discussion may also in itself have a value for the research community. These goals rely on the existence of a lively review discussion, but several experiments with open-process peer review in recent years have encountered the problem of faltering review discussions. The present article addresses the question of how lively review discussion may be fostered by relating the experience of the journal Electronic Transactions on Artificial Intelligence (ETAI) which was an early experiment with open peer review. Factors influencing the discussion activity are identified. It is observed that it is more difficult to obtain lively discussion when the number of contributed articles increases, which implies difficulties for scaling up the open peer review model. Suggestions are made for how this difficulty may be overcome. PMID:22363282

    Smith, Laura G E; Postmes, Tom

    2011-03-01

    In two studies, we demonstrate that small group discussions change the extent to which an activated stereotype affects performance in a relevant domain. In Study 1, female participants were asked why men are (or are not) better than them at maths. They generated their answers individually or through group discussion, and their subsequent maths performance was highest when they collectively challenged the stereotype and lowest when they collectively affirmed the stereotype. When participants affirmed the stereotype through discussion, they used more theories which supported the validity of the stereotype, compared to the individual thought condition; and consensus mediated the effect of group discussion on performance (relative to individual rumination). In Study 2, male and female participants affirmed or challenged the stereotype in same-gender discussion groups. After affirming the stereotype, women's performance decreased relative to their baseline scores and men's performance was 'lifted'. In contrast, when they challenged the stereotype, there was no difference between the performance of men and women on the maths test. This pattern of effects was mediated by confidence in mathematical ability. The findings support the idea that topical small group discussions can, in the short term, differentially alter the impact that stereotypes have on performance. ©2010 The British Psychological Society.

All panelists and the audience were asked to address the following questions • Why is the second law taught in so many different ways? Why so many textbooks on thermodynamics? Why so many schools of thought? • Some say that thermodynamics is limited to equilibrium, others that it extends to nonequilibrium. How is entropy defined for nonequilibrium states?

  17. An uplifting discussion of T-duality

    Harvey, Jeffrey A.; Moore, Gregory W.

    2018-05-01

    It is well known that string theory has a T-duality symmetry relating circle compactifications of large and small radius. This symmetry plays a foundational role in string theory. We note here that while T-duality is order two acting on the moduli space of compactifications, it is order four in its action on the conformal field theory state space. More generally, involutions in the Weyl group W ( G) which act at points of enhanced G symmetry have canonical lifts to order four elements of G, a phenomenon first investigated by J. Tits in the mathematical literature on Lie groups and generalized here to conformal field theory. This simple fact has a number of interesting consequences. One consequence is a reevaluation of a mod two condition appearing in asymmetric orbifold constructions. We also briefly discuss the implications for the idea that T-duality and its generalizations should be thought of as discrete gauge symmetries in spacetime.

    Full Text Available Open Access (OA, like any other model or strategy for the dissemination of knowledge, carries with it clear benefits as well as costs and downsides. These vary depending on the OA strategy in question, and in order for OA to bring maximum benefit to the world of scholarship, its costs and benefits need be examined carefully and dispassionately so that the former can be maximized and the latter minimized. Unfortunately, the OA advocacy community tends to resist all attempts to examine OA in this way, to the point that those who approach OA in a spirit of critical analysis (rather than celebration and evangelism are attacked and punished. This article describes the problem, provides examples of it, and proposes strategies for promoting a more rigorous and analytical discussion of OA.

    Full Text Available The aging population as well as the sexual liberation has caused many taboos to be broken, and even greater access to drugs that stimulate sexual activity provided for the elderly a sense of greater security to maintain sexual activity, this has generated an increase in cases of AIDS in these individuals. AIDS is a disease caused by the HIV virus that affects the body's immune system and presented as one of the most complex and challenging ever faced by mankind pandemics. Sexuality in the elderly that was neglected by researchers, professionals and society in general, until very recently, today is cause for concern. Based on this, the objective of this study was a reflection on the process of aging of the population and a rising rate of HIV infection among the elderly. It is intended to emphasize that, despite its increase, this segment still appears to be invisible to the eyes of society and the state and that the frequency and quality of sexual activity has not been accompanied by information and actions for the prevention of sexually transmitted diseases that portion of the population.

  1. WTC. A discussion on built space regeneration

    Full Text Available Before 9/11 WTC was an international landmark. The definition of the two high-rise buildings identity, their tourist, social, visual and economic significance, disappeared with the destruction of their materiality. As a result, the contemplative visual and unwritten discourse of the Lower Manhattan disappeared together with the architectural, urban, technological essence and also with the philosophy of stability and equilibrium of a prosperous society. At the social-mental level this event triggers a crisis in personal and collective consciences (of the American Nation but also of the Nations, and a crisis of humanity. The architectural - urban and ideas competition organized to select the best urban-social-architectural concept proved to be a difficult task. Not only it had to “fill” a particular place on earth, but it also needed to configure a philosophy of place that would ‘heal” the wounds of the local and international communities, namely the lack of security and prosperity brought on by a no longer hidden technology of aggression bringing cities and communities under threats never experienced before at times of peace. In its first part the article discusses the competition, proposals and the finalized urban project. The particular challenges related to the selection of design in the case of WTC are doubled by a certain complexity related to the institutional arrangements common to most large urban development projects. It is also clear that there is interdependency between the project governance and the project results. These aspects are discussed in the second part of the article.

  2. Round-table discussion on food irradiation

    The possibilities of using radiation for food preservation as a way of alleviating the food deficiency problem in a large part of the world has been studied for some 20 years. Since the idea was recognized as a viable one, scientists had to develop it along three levels: firstly, the technological problems and economic viability had to be faced; at the same time tests had to be initiated to prove the wholesomeness of the irradiated foodstuffs, and then public acceptance and confidence in the end product had to be established. Work is proceeding along these three lines and in some cases, success has been won on all fronts. In others, it is continuing. As a FLASHBACK to the situation TWO YEARS AGO, we thought it interesting to reprint excerpts from a round-table discussion at which scientists from five countries sat down to discuss the pros and cons of food irradiation. ost at the gathering was Dr. Rocco Basson, Director of Chemistry at Pelindaba, South Africa, and the man responsible for directing radiation processing in that country. With him were Dr. Lapidot, Head of the Radiation and Engineering and Processing Section of the Israel Atomic Energy Commission at Soreq; Dr. Saint-Lebe of the Radioagronomy Service, French Atomic Energy Commission, at Cadarache; Dr. Ulmann, then Director of the Food Irradiation Pilot Plant at Wageningen in Holland; and Mr. Roy Hickman, leader of the International Project in the Field of Irradiation, sponsored by the FAO, IAEA and the OECD Nuclear Energy Agency, centred at Karlsruhe in Germany.

    To investigate the cervical microleakage in Class II cavities restored with Sonicsys approx ceramic inserts and four resin-based materials. Forty noncarious and crack-free mandibular third molars were used. These teeth were randomly assigned to four groups each containing 10 teeth. No control group was created. On each tooth, one mesial boxlike cavity was prepared using the active head Sonicsys approx no. 3. The cervical margin of each cavity was in enamel about 1 mm coronal to the cementoenamel junction. According to manufacturer's instructions, the prepared cavities were restored using a Sonicsys approx ceramic inserts no.3 and four resin-based materials as follows: group 1, Tetric Flow; group 2, Admira Flow; group 3, Nexus 2; group 4, X-Flow. After finishing and polishing, all specimens were stored in distilled water for 7 days at 37 degrees C, thermocycled 1,000 cycles between 5 degrees and 55 degrees C, and stored for 24 hours in basic fuchsine 2%. All specimens were then embedded in clear acrylic resin and sectioned along a mesial-distal plane through the middle of the cervical margin. The cervical areas of the resulting sections were examined using an optical microscope to assess the dye penetration. The registered scores were analyzed using Kruskal-Wallis and Mann-Whitney U tests. Microleakage was detected in each experimental group. Kruskal-Wallis test revealed statistically significant differences among groups (P = .009, alpha = .01). The Mann-Whitney U test showed significant differences between Admira Flow group and Tetric Flow (P = .011, alpha = .05), Nexus 2 (P = .001, alpha = .01), and X-Flow (P = .004, alpha = .01), respectively. Within the limitations of this study, the extent of microleakage in the cervical area (enamel) of Class II cavities restored with Sonicsys approx ceramic inserts depends on the material used for luting. The highest leakage occurred when Admira flow was used.

  4. The nuclear power discussion in change. Nuclear controversy has shifted

    International Nuclear Information System (INIS)

    Schmidt-Kuester, Wolf J.; Popp, Manfred

    2015-01-01

    The public discussion on nuclear energy is not focused on power plant safety anymore. A globally good safety statistic and years of information activity on safety technology provided progress, even though all incidents are still discussed with great dedication. Nevertheless the field of disposal receives more prominence in public discussions since 1976; reprocessing of irradiated fuels and storage of nuclear waste follow the topic of nuclear power plants with temporary shift. During a long preparation time technical and operational know-how was gathered for both fields that is now available for use on large technical scale. For the entire disposal complex exists a comprehensive concept prepared by the federal government, which has to be put into practice together with the industry. The priority assignment for a dialogue with the public is to comprehensively inform on extend and quality of problem solutions and to highlight that even here the safety of the biological-cycle is the guiding principle for all considerations.

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 4, 2007) following the short presentations—each reported as a separate article in the present volume—by Seth Lloyd, Owen Maroney, Silviu Guiasu, Ping Ao, Jochen Gemmer, Bernard Guy, Gian Paolo Beretta, Speranta Gheorghiu-Svirschevski, and Dorion Sagan. All panelists and the audience were asked to address the following questions • Why is the second law true? Is it an inviolable law of nature? If not, is it possible to develop a perpetual motion machine of the second kind? • Are second law limitations objective or subjective, real or apparent, due to the nature of physical states or the representation and manipulation of information? Is entropy a physical property in the same sense as energy is universally understood to be an intrinsic property of matter? • Does the second law conflict with quantum mechanics? Are the differences between mechanical and thermodynamic descriptions of physical phenomena reconcilable? Does the reversible law of motion of hamiltonian mechanics and quantum mechanics conflict with the empirical observation of irreversible phenomena?

Based on the trend of historical data, some forecast that second-law efficiency of energy conversion will reach 80% by the end of the century. What technologies are at sight that might hold this promise? • Nanotechnologies and microtechnologies point towards the development of microscopic heat engines? How do second law limitations map down to these scales? • Combustion is the principal way of converting the chemical energy of fossil fuels to thermal energy, but it is highly irreversible. Are there promising ways to reduce combustion irreversibility? Are fuel cells the only alternative to combustion?

    2010-11-01

    With the rapid development of information science, the ancient Traditional Chinese Medicine is combining with it rapidly, and forming a new discipline: Traditional Chinese Medicine (TCM) Informatics. TCM information digitalization is the process of digital processing, which uses modern information technology to obtain, process, store, and analyze TCM-related data, information, and knowledge. It gathers research, application development, and service in an integrated whole. This article systematically analyzes the key research issues of TCM informatics (e.g., on data resources, data standard, data system construction). Also, the methodology and technology of TCM information digitalization research are thoroughly discussed. The starting point of the research on traditional Chinese medical information digitalization was in question. The research from the current study research was drawn from collected information that was stored, transferred, and utilized. This process helped to place an emphasis on the topic, as well as extending its research areas. In addition, an innovative TCM information virtual study center was set up to support a great deal of fundamental work.

    A review of the Dizziness Handicap Inventory (DHI). NUMBER OF STUDIES: Seventy-four studies. Articles published between January 1990 and May 2012 were identified by searches in PubMed electronic database. Of the 227 articles meeting the inclusion criteria 74 were reviewed. These articles are discussed under nine topics; Reliability, validity and internal consistency of the original version of DHI, relationship between vestibular/balance tests and DHI, association between DHI and the other scales related to balance impairments, exploratory factor analysis of the DHI, screening version of DHI, translations of DHI into other languages, the role of DHI to assess the success of the treatment of balance disorder, DHI results in various vestibular disorders, general characteristics of DHI in patients with balance impairment. Self reported measures represent unique pieces of the information important for the management of dizzy patients. DHI is the most widely used self reported measurement of patients with dizziness. It has been translated into fourteen languages, so it is widely accepted.

  15. Discussion on posting and labeling for radioprotection

    International Nuclear Information System (INIS)

    Suzuki, Fabio F.

    2009-01-01

    The radioprotection aims the protection of people against exposure to ionizing radiation or radioactive substances as well as the safety of radiation sources. As ionizing radiation is not perceived by human senses, the warning signs and labels on radiation sources and the safety posters in controlled and supervised areas have an important role to keep the doses and risks as low as reasonably achievable, to prevent radiological accidents and to mitigate their consequences. In Brazil, several technical regulations require such safety labels and posters, however, despite their importance, there is quite few guidance about their format or contents. In this paper the posting and labeling requirements for radiological control existing in Brazilian technical regulations are discussed, confronting them with national, foreign and international technical standards and by drawing up a parallel with requirements of technical regulations from other countries. Changes are suggested in some parts of the national regulations, to prevent some differences in the current guidance, allowing the optimization of posting and labeling programs of radiological facilities.

    1999-12-01

    Full Text Available The research programme on vicarious learning, part of which we report in this paper, has been aimed at exploring the idea that learning can be facilitated by providing learners with access to the experiences of other learners. We use Bandura's term vicarious learning to describe this (Bandura, 1986, and we believe it to be a paradigm that offers particular promise when seen as an innovative way of exploiting recent technical advances in multimedia and distance learning technologies. It offers the prospect of a real alternative to the building of intelligent tutors (which directly address the problem of allowing learners access to dialogue, but which have proved largely intractable in practice or to the direct support of live dialogues (which do not offer a solution to the problem of providing 'live' tutors - unless they are between peer learners. In the research reported here our main objectives were to develop techniques to facilitate learners' access to, especially, dialogues and discussions which have arisen when other learners were faced with similar issues or problems in understanding the material. This required us to investigate means of indexing and retrieving appropriate dialogues and build on these to create an advanced prototype system for use in educational settings.

  17. Indigenous healing practice: ayahuasca. Opening a discussion.

    Science.gov (United States)

    Prue, Robert; Voss, Richard W

    2014-01-01

    This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon, particularly as a curing ritual for drug addiction (Dobkin de Rios, 1970; Moir, 1998). Like peyote in the United States (Calabrese, 1997) ayahuasca use amongst the indigenous people of the Amazon is a form of cultural psychiatry. A review of the literature reveals very little commentary or discussion of shamanic practice in Pastoral Counseling (Pastoral Theology). The scant literature identifies an antithetical relationship at best. The current authors wonder about the possibility of to including shamanic practices in the context of pastoral counseling? This essay seeks to provide some basic information about the ritual use of ayahuasca and to offer a rationale for pastoral counselors to engage in a dialogue about its utility.

  18. Discussion of entanglement entropy in quantum gravity

    International Nuclear Information System (INIS)

    Ma, Chen-Te

    2018-01-01

    We study entanglement entropy in gravity theory with quantum effects. A simplest model is a two dimensional Einstein gravity theory. We use an n-sheet manifold to obtain an area term of entanglement entropy by summing over all background fields. Based on AdS/CFT correspondence, strongly coupled conformal field theory is expected to describe perturbative quantum gravity theory. An ultraviolet complete quantum gravity theory should not depend on a choice of an entangling surface. To analysis the problem explicitly, we analyze two dimensional conformal field theory. We find that a coefficient of a universal term of entanglement entropy is independent of a choice of an entangling surface in two dimensional conformal field theory for one interval to show a tentative evidence. Finally, we discuss that translational invariance in a quantum system at zero temperature, size goes to infinity and no mass scales, except for cut-off, possibly be a necessary condition in quantum gravity theory by ruing out a volume law of entanglement entropy.

    Active learning has gained increasing support as an effective pedagogical technique to improve student learning. One way to promote active learning in the classroom is the use of in-class activities in place of lecturing. As part of an NSF-funded project, a set of in-class activities have been created that use climate change topics to teach chemistry content. These activities use the Process Oriented Guided Inquiry Learning (POGIL) methodology. In this pedagogical approach a set of models and a series of critical thinking questions are used to guide students through the introduction to or application of course content. Students complete the activities in their groups, with the faculty member as a facilitator of learning. Through assigned group roles and intentionally designed activity structure, process skills, such as teamwork, communication, and information processing, are developed during completion of the activity. Each of these climate change activities contains a socio-scientific component, e.g., social, ethical and economic data. In one activity, greenhouse gases are used to explain the concept of dipole moment. Data about natural and anthropogenic production rates, global warming potential and atmospheric lifetimes for a list of greenhouse gases are presented. The students are asked to identify which greenhouse gas they would regulate, with a corresponding explanation for their choice. They are also asked to identify the disadvantages of regulating the gas they chose in the previous question. In another activity, where carbon sequestration is used to demonstrate the utility of a phase diagram, students use economic and environmental data to choose the best location for sequestration. Too often discussions about climate change (both in and outside the classroom) consist of purely emotional responses. These activities force students to use data to support their arguments and hypothesize about what other data could be used in the corresponding discussion to

  20. The Topology of a Discussion: The #Occupy Case.

    Directory of Open Access Journals (Sweden)

    Floriana Gargiulo

    Full Text Available We analyse a large sample of the Twitter activity that developed around the social movement 'Occupy Wall Street', to study the complex interactions between the human communication activity and the semantic content of a debate.We use a network approach based on the analysis of the bipartite graph @Users-#Hashtags and of its projections: the 'semantic network', whose nodes are hashtags, and the 'users interest network', whose nodes are users. In the first instance, we find out that discussion topics (#hashtags present a high structural heterogeneity, with a relevant role played by the semantic hubs that are responsible to guarantee the continuity of the debate. In the users' case, the self-organisation process of users' activity, leads to the emergence of two classes of communicators: the 'professionals' and the 'amateurs'.Both the networks present a strong community structure, based on the differentiation of the semantic topics, and a high level of structural robustness when certain sets of topics are censored and/or accounts are removed.By analysing the characteristics of the dynamical networks we can distinguish three phases of the discussion about the movement. Each phase corresponds to a specific moment of the movement: from declaration of intent, organisation and development and the final phase of political reactions. Each phase is characterised by the presence of prototypical #hashtags in the discussion.

  1. Frequency of Faith and Spirituality Discussion in Health Care.

    Science.gov (United States)

    Bergamo, David; White, Dawn

    2016-04-01

    Faith and spirituality are important in the lives of many individuals, and therefore, many patients. This study was performed to determine whether faith and spirituality are active part of the healthcare field and patients' receipt of these sometimes delicate topics. The nuances of the concepts of faith, spirituality, and religion and their implications in the healthcare setting are discussed. Benefits and detriments of faith and spirituality are reviewed in terms of how they relate to the health of the patient and to the healthcare field. With the focus of healthcare shifting to holistic care, this conversation may be more necessary than ever in practice, yet it seems many providers are not discussing these matters with patients. The study analyzes whether healthcare providers are discussing these topics with patients and how the discussion is received or would be received by patients. Findings demonstrate the infrequency of the discussion regardless of the fact that the majority of patients consider themselves faithful or spiritual. This study was approved by the Clarkson University Institutional Review Board on June 18, 2104.

    In Africa, Centres of Excellence should be oriented to build up scientific and technological capacity in the four topics of international Monitoring System related technologies, namely, seismic monitoring, hydro acoustic monitoring, infrasound monitoring and radionuclides monitoring. Training programs on these topics should be a major objective. A network of such centres should be established in a number of African countries. Centres should be equipped with means and materials for on-line course dispatch to interested training centres or research institutions. African centres should develop strong relationship among themselves through information and data exchange and sharing, harmonization of training programs. National data centres may be established as a component of the African Centre of Excellence. States Signatories may authorize the establishment of a specific fund to support the activities of the African center

    2014-03-01

    Full Text Available The task of identifying named entities from the discussion texts in Web forums faces the challenge of noisy names. As the names are often misspelled or abbreviated, the conventional techniques have failed to detect the noisy names properly. In this paper we propose a global context based framework for handling the noisy names. The framework is tested on a named entity recognition system designed to identify the names from the discussion texts in a homeopathy diagnosis discussion forum. The proposed global context-based framework is found to be effective in improving the accuracy of the named entity recognition system.

  4. [Demand for abortion. Pre-abortion discussion].

    Guiol, L

    1994-03-01

    The preabortion interview required by French law takes place between the medical consultation and the aspiration or administration of RU-486. The three marriage counselors at the Center for Social Gynecology in Marseilles have each undertaken a course of personal therapy to enable them to understand their own reactions and motivations as a way of improving their effectiveness with clients. The preabortion interview is an opportunity to listen to and support women who may be experiencing anguish, sadness, ambivalence, or aggressivity. Each client determines the content of the interview. Often the reason for the abortion is given, frequently in terms of economic problems, unemployment, or other justification. The women almost always state that they "cannot", not that they "do not want", to continue the pregnancy, as if external circumstances had made their decision. The decision is usually made with little discussion. Young adolescents are often astounded to find themselves pregnant. Among young girls, the pregnancy may represent an appeal to the parents for attention or understanding. Sometimes the abortion represents a repetition or a reminder of some difficult event in the past, such as a previous abortion or the death of a child. Often the abortion exacerbates problems in the couple's relationship. The mother often experiences rejection of the pregnancy by the father as rejection of herself. Repeat abortions raise questions about whether some aspect of counseling was neglected. The abortion request always occasions a great feeling of guilt, both for being pregnant and for refusing the pregnancy. The interview permits the client to express her feelings and may help her make sense of the experience.

  5. Do randomized controlled trials discuss healthcare costs?

    Directory of Open Access Journals (Sweden)

    G Michael Allan

    Full Text Available BACKGROUND: Healthcare costs, particularly pharmaceutical costs, are a dominant issue for most healthcare organizations, but it is unclear if randomized controlled trials (RCTs routinely discuss costs. Our objective was to assess the frequency and factors associated with the inclusion of costs in RCTs. METHODS AND FINDINGS: We randomly sampled 188 RCTs spanning three years (2003-2005 from six high impact journals. The sample size for RCTs was based on a calculation to estimate the inclusion of actual drug costs with a precision of +/-3%. Two reviewers independently extracted cost data and study characteristics. Frequencies were calculated and potential characteristics associated with the inclusion of costs were explored. Actual drug costs were included in 4.7% (9/188 of RCTs; any actual costs were included in 7.4% (14/188 of RCTs; and any mention of costs was included in 27.7% (52/188 of RCTs. As the amount of industry funding increased across RCTs, from non-profit to mixed to fully industry funded RCTs, there was a statistically significant reduction in the number of RCTs with any actual costs (Cochran-Armitage test, p = 0.005 and any mention of costs (Cochran-Armitage test, p = 0.02. Logistic regression analysis also indicated funding was associated with the inclusion of any actual cost (OR = 0.34, p = 0.009 or any mention of costs (OR = 0.63, p = 0.02. Journal, study conclusions, study location, primary author's country and product age were not associated with inclusion of cost information. CONCLUSION: While physicians are encouraged to consider costs when prescribing drugs for their patients, actual drug costs were provided in only 5% of RCTs and were not mentioned at all in 72% of RCTs. Industry funded trials were less likely to include cost information. No other factors were associated with the inclusion of cost information.

  6. Pulsar velocity observations: Correlations, interpretations, and discussion

    Helfand, D.J.; Tademaru, E.

    1977-01-01

    From an examination of the current sample of 12 pulsars with measured proper motions and the z-distribution of the much larger group of over 80 sources with measured period derivatives, we develop a self-consistent picture of pulsar evolution. The apparent tendency of pulsars to move parallel to the galactic plane is explained as the result of various selection effects. A method for calculating the unmeasurable radial velocity of a pulsar is presented; it is shown that the total space velocities thus obtained are consistent with the assumption of an extreme Population I origin for pulsars which subsequently move away from the plane with a large range of velocities. The time scale for pulsar magnetic field decay is derived from dynamical considerations. A strong correlation of the original pulsar field strength with the magnitude of pulsar velocity is discussed. This results in the division of pulsars into two classes: Class A sources characterized by low space velocities, a small scale height, and low values of P 0 P 0 ; and Class B sources with a large range of velocities (up to 1000 km s -1 ), a much greater scale height, and larger values of initial field strength. It is postulated that Class A sources originate in tight binaries where their impulse acceleration at birth is insufficient to remove them from the system, while the Class B sources arise from single stars or loosely bound binaries and are accelerated to high velocities by their asymmetric radiation force. The evolutionary picture which is developed is shown to be consistent with a number of constraints imposed by supernova rates, the relative frequency of massive binaries and Class A sources, theoretical field-decay times, and the overall pulsar galactic distribution

The Western Samoa legislator urged delegates to be aware of human development that was no more than the promotion of values associated with a market economy. Samoans increased their per capita caloric consumption. The food supply is provided locally, and 90% of exports are food products. Food security would be jeopardized by a fivefold increase in population. Samoan human development indicators were relatively good for a developing country. However, the country was still ranked as a low-income, food-deficit country. The Pakistani delegate explained that Pakistan's agriculture used the largest, continuous irrigation system in the world. However, the system operated inefficiently. There was concern that future high population growth would jeopardize food security. Another barrier was institutional mismanagement of irrigation and reliance on imports for staple items. Agricultural productivity must increase to meet the increased needs of continued population growth. All available land is currently under cultivation. Future strategies will necessitate international cooperation and innovative and environmentally sound technology. Professor Xuan remarked that increased population growth and rising demand, decreased water quality, and changing consumption patterns were a threat to water supplies. Sustainable increases in food production would entail better water management: reforestation to reduce and prevent water runoff, better technological exploitation of rain water, and more efficient use of irrigation systems. Better international financing schemes were needed for support of these policy changes. Professor Ness suggested free markets in water in order to price water at actual rates of consumption. Polluters should pay. Water management was also threatened by global warming.

    Healthcare costs, particularly pharmaceutical costs, are a dominant issue for most healthcare organizations, but it is unclear if randomized controlled trials (RCTs) routinely discuss costs. Our objective was to assess the frequency and factors associated with the inclusion of costs in RCTs. We randomly sampled 188 RCTs spanning three years (2003-2005) from six high impact journals. The sample size for RCTs was based on a calculation to estimate the inclusion of actual drug costs with a precision of +/-3%. Two reviewers independently extracted cost data and study characteristics. Frequencies were calculated and potential characteristics associated with the inclusion of costs were explored. Actual drug costs were included in 4.7% (9/188) of RCTs; any actual costs were included in 7.4% (14/188) of RCTs; and any mention of costs was included in 27.7% (52/188) of RCTs. As the amount of industry funding increased across RCTs, from non-profit to mixed to fully industry funded RCTs, there was a statistically significant reduction in the number of RCTs with any actual costs (Cochran-Armitage test, p = 0.005) and any mention of costs (Cochran-Armitage test, p = 0.02). Logistic regression analysis also indicated funding was associated with the inclusion of any actual cost (OR = 0.34, p = 0.009) or any mention of costs (OR = 0.63, p = 0.02). Journal, study conclusions, study location, primary author's country and product age were not associated with inclusion of cost information. While physicians are encouraged to consider costs when prescribing drugs for their patients, actual drug costs were provided in only 5% of RCTs and were not mentioned at all in 72% of RCTs. Industry funded trials were less likely to include cost information. No other factors were associated with the inclusion of cost information.

  9. Bioethics and multiculturalism: nuancing the discussion.

    2018-02-01

    In his recent analysis of multiculturalism, Tom Beauchamp has argued that those who implement multicultural reasoning in their arguments against common morality theories, such as his own, have failed to understand that multiculturalism is neither a form of moral pluralism nor ethical relativism but is rather a universalistic moral theory in its own right. Beauchamp's position is indeed on the right track in that multiculturalists do not consider themselves ethical relativists. Yet, Beauchamp tends to miss the mark when he argues that multiculturalism is in effect a school of thought that endorses a form of moral universalism that is akin to his own vision of a common morality. As a supporter of multiculturalism, I would like to discuss some aspects of Beauchamp's comments on multiculturalism and clarify what a multicultural account of public bioethics might look like. Ultimately, multiculturalism is purported as a means of managing diversity in the public arena and should not be thought of as endorsing either a version of moral relativism or a universal morality. By simultaneously refraining from the promotion of a comprehensive common moral system while it attempts to avoid a collapse into relativism, multiculturalism can serve as the ethico-political framework in which diverse moralities can be managed and in which opportunities for ethical dialogue, debate and deliberation on the prospects of common bioethical norms are made possible. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Detection for space application is very demanding on the IR detector: all wavelengths, from visible-NIR (2- 3um cutoff) to LWIR (10-12.5um cutoff), even sometimes VLWIR (15um cutoff) may be of interest. Moreover, various scenarii are usually considered. Some are imaging applications where the focal plane array (FPA) is used as an optical element to sense an image. However, the FPA may also be used in spectrometric applications where light is triggered on the different pixels depending on its wavelength. In some cases, star pointing is another use of FPAs where the retina is used to sense the position of the satellite. In all those configurations, we might distinguish several categories of applications: • low flux applications where the FPA is staring at space and the detection occurs with only a few number of photons. • high flux applications where the FPA is usually staring at the earth. In this case, the black body emission of the earth and its atmosphere ensures usually a large number of photons to perform the detection. Those two different categories are highly dimensioning for the detector as it usually determines the level of dark current and quantum efficiency (QE) requirements. Indeed, high detection performance usually requires a large number of integrated photons such that high QE is needed for low flux applications, in order to limit the integration time as much as possible. Moreover, dark current requirement is also directly linked to the expected incoming flux, in order to limit as much as possible the SNR degradation due to dark charges vs photocharges. Note that in most cases, this dark current is highly depending on operating temperature which dominates detector consumption. A classical way to mitigate dark current is to cool down the detector to very low temperatures. This paper won't discuss the need for wavefront sensing where the number of detected photons is low because of a very narrow integration window. Rigorously, this kind of

    As the task of the engineering design activity of the international thermonuclear fusion experimental reactor (ITER), on 316 type stainless steel (SS316) and the compound system of SS316 and water, the shielding experiment using the D-T neutron source of FNS in Japan Atomic Energy Research Institute has been carried out. However, in these analyses, enormous working time and computing time were required for determining the Weight Window parameter. Limitation or complication was felt when the variance reduction by Weight Window method of MCNP code was carried out. For the purpose of avoiding this difficulty, investigation was performed on the effectiveness of the variance reduction by cell importance method. The conditions of calculation in all cases are shown. As the results, the distribution of fractional standard deviation (FSD) related to neutrons and gamma-ray flux in the direction of shield depth is reported. There is the optimal importance change, and when importance was increased at the same rate as that of the attenuation of neutron or gamma-ray flux, the optimal variance reduction can be done. (K.I.)

    A massive open online course, or MOOC, is an noncredit education activity that delivers learning content to anyone with access to the Internet. Individual courses are generally free of charge, while a certificate can have small costs. The University of Wisconsin-Madison has exploring the use of MOOC as part of its Wisconsin Idea. In the 2015, a series of MOOCs focusing on the environment were offered via Coursera. One of those MOOCS was "Changing Weather and Climate of the Great Lakes Region." This 4-week course features a new season each week through short lectures and activities covering Great Lakes weather, observed changes in the climate, and societal impacts of climate change. (https://www.coursera.org/course/greatlakesclimate) The MOOC conveyed information from NOAA's National Weather Service (NWS) Weather-Ready Nation initiative as well as findings from the recent National Climate Assessment and the Wisconsin Initiative on Climate Change Impacts (WICCI). The course was organized by members of the Department of Atmospheric and Oceanic Sciences and the Cooperative Institute for Meteorological Satellite Studies; material included discussion, videos for lectures as well as guest lecturers. There were also weekly visits by the course team to 21 public libraries throughout the state of WI. The library collaboration as facilitated by WiLS (Wisconsin Library Services - wils.org), who organized the application and selection process. The public libraries hosted local residents and course instructors in discussions of course content in the context of their communities as well as strategies to mitigate the climate change impacts. This presentation will discuss the public library discussions experience and the our evaluation of the impact of including a face-to-face component in the MOOC activity on engagement and learning.

  19. Discussion paper : offshore wind facilities renewable energy approval requirements

    International Nuclear Information System (INIS)

    2010-06-01

    This paper discussed a proposed shoreline exclusion zone for offshore wind projects in Ontario. Considerations relevant to offshore wind projects and the protection of human health, cultural heritage, and the environment were also discussed. The paper was prepared in order to provide greater clarity to renewable energy developers and to Ontario residents about the offshore wind policy that is currently being considered by the Ontario Government. Feedback received from the discussion paper will be used to propose policy and associated regulatory amendments. A 5 km shoreline exclusion zone for all offshore wind facilities was proposed. Some projects may be required to be located beyond the proposed exclusion zone. Proposed developments within the exclusion zone must meet all applicable requirements, including those related to cultural and natural heritage. The zone will establish a distance between drinking water intakes, and ensure that sediment dredging and other construction-related activities do not impact drinking water quality, and ensure that potential noise levels are within acceptable levels. The zone will establish a distance between near-shore activities and wind facilities, and also help to maintain the ecological health of inland waters. Guidelines and technical requirements for wind facility operators were also included.

    2016-01-01

    An increasing number of individuals turn to online health communities (OHC) for information, advice and support about their health condition or disease. As a result of users' active participation, these forums store overwhelming volumes of information, which can make access to this information challenging and frustrating. To help overcome this problem we designed a discussion visualization tool DisVis. DisVis includes features for overviewing, browsing and finding particular information in a discussion. In a between subjects study, we tested the impact of DisVis on individuals' ability to provide an overview of a discussion, find topics of interest and summarize opinions. The study showed that after using the tool, the accuracy of participants' answers increased by 68% (p-value = 0.023) while at the same time exhibiting trends for reducing the time to answer by 38% with no statistical significance (p-value = 0.082). Qualitative interviews showed general enthusiasm regarding tools for improving browsing and searching for information within discussion forums, suggested different usage scenarios, highlighted opportunities for improving the design of DisVis, and outlined new directions for visualizing user-generated content within OHCs.

    2013-01-01

    One of the most important skills in medicine is communication. It lies at the heart of the doctor-patient relationship, and is particularly important when one has been diagnosed with a potentially life-threatening condition. Words are powerful and too often can be interpreted in ways not intended. In our session at the 2013 ASCO Annual Meeting, we discuss the communication of cancer and ways we might want to consider discussions regarding treatment options and prognosis. We recognize that all patients are different and that approaches should be individualized, to reflect each person's needs (what they want to know) while respecting their limits (how much they want to know). We discuss the concept of shared decision making, and how it can be used when there is uncertainty in what treatments may (or may not) accomplish. Finally, we discuss the skills that constitute a toolkit for communication, which we hope can be tailored to meet the variable needs of those we are caring for and by doing so, can be of help to clinicians in their own practices. In the era of personalized medicine, treatments may become more complex, and more options may be available. We hope to encourage providers to welcome patients as active participants in their care by sharing information, requesting their input, and by engaging them in important processes such as advance care planning-to ensure their needs and wishes are respected in the present and for whatever may come in the future.

    A new informal activity, Technical discussions on Emissions and Atmospheric Modeling (TEAM), aims to improve the scientific understanding of emissions and atmospheric processes by leveraging resources through coordination, communication and collaboration between scientists in the Nation's environmental agencies. TEAM seeks to close information gaps that may be limiting emission inventory development and atmospheric modeling and to help identify related research areas that could benefit from additional coordinated efforts. TEAM is designed around webinars and in-person meetings on particular topics that are intended to facilitate active and sustained informal communications between technical staff at different agencies. The first series of TEAM webinars focuses on emissions of nitrogen oxides, a criteria pollutant impacting human and ecosystem health and a key precursor of ozone and particulate matter. Technical staff at Federal agencies with specific interests in emissions and atmospheric modeling are welcome to participate in TEAM.

  6. Administering Spatial and Cognitive Instruments In-class and On-line: Are These Equivalent?

    Williamson, Kenneth C.; Williamson, Vickie M.; Hinze, Scott R.

    2017-02-01

    Standardized, well-established paper-and-pencil tests, which measure spatial abilities or which measure reasoning abilities, have long been found to be predictive of success in the STEM (science, technology, engineering, and mathematics) fields. Instructors can use these tests for prediction of success and to inform instruction. A comparative administration of spatial visualization and cognitive reasoning tests, between in-class (proctored paper and pencil) and on-line (unproctored Internet) ( N = 457), was used to investigate and to determine whether the differing instrument formats yielded equal measures of spatial ability and reasoning ability in large first-semester general chemistry sections. Although some gender differences were found, findings suggest that some differences across administration formats, but that on-line administration had similar properties of predicting chemistry performance as the in-class version. Therefore, on-line administration is a viable option for instructors to consider especially when dealing with large classes.

    2014-01-01

    The safety-related fuses used in class-1E power system provide overcurrent protection for electrical system and isolate the class 1E circuit from a fault or overload condition. These days, the number of nuclear grade suppliers has been reduced. Accordingly, commercial grade, instead of safety-related, fuses are procured and used in the utilities through the dedication process. Therefore, this paper introduces the commercial grade fuse dedication process/engineering and how to assure the quality requirements with this process and engineering. The fuses used in class-1E power system are to protect overcurrent and to isolate fault. Therefore the fuse for acceptance in order to improve the quality and reliability for commercial grade fuses shall be dedicated. The fuse resistance value may be useful as an indicator of acceptance. The current carrying capacity test can change the fuse performance properties. Therefore these critical characteristics are needed for additional review and analysis with fuse manufactures

    The most frequent extraction regime consists of the removal of upper and lower premolars. Depending on anchorage requirements, camouflage treatment options, surgical intervention, or the absence of teeth in only one arch, it may become necessary to finalize the occlusion with a one-dental-unit discrepancy between the upper and lower dental arches. Guidelines are presented for finishing occlusions in Class II or Class III molar relation.

    Full Text Available Video is being used widely in professional development. Yet, little is known about how to design video-based learning environments that are productive for teacher learning. One promising model is a video club (Sherin, 2000. Video clubs bring teachers together to view and analyze video segments from one another’s classrooms. The idea is that by watching and discussing video segments focused on student thinking, teachers will learn practices for identifying and analyzing noteworthy student thinking during instruction and can use what they learn to inform their instructional decisions. This paper addresses issues to consider when setting up a video club for teacher education, such as defining goals for using video, establishing norms for viewing and discussing one another’s teaching, selecting clips for analysis, and facilitating teacher discussions. Si consiglia la discussione tra osservatori. Nei Video Club gli insegnanti mettono a fuoco le modalità con cui gli studenti apprendono.Il video è stato ampiamente utilizzato per la formazione professionale.

    Patient recall of treatment information is a key variable towards chronic disease (CD) management. It is unclear what communication and patient participation characteristics predict recall. To assess what aspects of doctor-patient communication predict patient recall of medication information. To describe lifestyle treatment recall, in CD primary care patients. Observational study within a RCT. Community-based primary care (PC) practices. Family physicians (n=18): practicing >5 years, with a CD patient caseload. Patients (n=159): >40 years old, English speaking, computer literate, off-target hypertension, type II diabetes and/or dyslipidaemia. Patient characteristics: age, education, number of CDs. Information characteristics: length of encounter, medication status, medication class. Communication variables: socio-emotional utterances, physician dominance and communication control scores and PACE (ask, check and express) utterances, measured by RIAS. Number of medication themes, dialogue and initiative measured by MEDICODE. Recall of CD, lifestyle treatment and medication information. Frequency of lifestyle discussions varied by topic. Patients recalled 43% (alcohol), 52% (diet) to 70% (exercise) of discussions. Two and a half of six possible medication themes were broached per medication discussion. Less than one was recalled. Discussing more themes, greater dialogue and patient initiative were significant predictors of improved medication information recall. Critical treatment information is infrequently exchanged. Active patient engagement and explicit conversations about medications are associated with improved treatment information recall in off-target CD patients followed in PC. Providers cannot take for granted that long-term off-target CD patients recall information. They need to encourage patient participation to improve recall of treatment information. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

    To evaluate gender differences of initial posters in threads dealing with bladder cancer on an online discussion board. 529 threads opened between 09/2005 and 03/2012 were screened on the largest German speaking bladder cancer online discussion board. 366 threads fulfilled the requirements for this study. Gender, age, number, status of concern and oncological situation of initiating posters as well as their motives and language style were analyzed following a standardized protocol. Threads were initiated in 45% (164/366) by men and in 55% (202/366) by women. Mean age of male initiating posters was 50 years and of female posters 44 years (p posters asked for medical information or therapeutic recommendations regarding diagnosis, treatment and prognosis. However, women significantly more often expressed their wish for emotional support (p = 0.034) and in tendency wanted to share their experiences with others (p = 0.057). Language analysis revealed that women significantly more often used a tentative language style than men (p = 0.003). Even though women are less often affected by bladder cancer, they are more active -especially for their concerned family members - on the evaluated discussion board than men. Whereas both genders equally often ask for medical information, women more often want to share their experiences and look for emotional support.

    International Nuclear Information System (INIS)

    Guigue, J.

    1994-01-01

    A brief survey involving 30 history and geography teachers from the Paris region shows that they address nuclear energy in class. National programs allow various approaches at different levels, without really focusing on the subject. The discussion brings the question down to a trivial issue, in accordance with the general french consensus, but that does not prevent pupils from asking questions, preoccupied as they are by certain choices which have already been made for the future. In order to answer those questions to the best extent possible in view of the underlying ethical problem, teachers would welcome better training, up-to-date, pluri-disciplinary and objective information, as well as appropriate and easy-to-use educational material

    2016-07-01

    Full Text Available This paper presents an exploratory action research study carried out by two English as a foreign language teachers in a private, non-profit institution in Bogota, Colombia, with a group of 12 learners in a B1 English course. These students faced difficulties elaborating on their ideas when discussing issues in class. The study placed emphasis on the use of argumentation outlines and peer assessment to boost learners’ argumentative abilities. Audio-taped conversations and open-ended interviews were used to understand the impact on the pedagogical intervention. Findings revealed that argumentation outlines and peer assessment can promote learners’ awareness and ability to engage in argumentation processes. Moreover, peer assessment appears to be an essential tool for enhancing personal and collaborative learning, as well as for promoting learner reflection and agency.

    Full Text Available Astrology, a pseudoscience, is highly popular in Turkey. Astrologers, who are its practitioners, produce discourses in the scientific field at the media and at their own platforms. Furthermore, it is possible to find some instances of astrology related activities in Turkish universities. In this article, demarcation of science from pseudoscience and the pseudoscientific status of astrology were discussed in a first place. Next, threats of astrological discourse within economic, educational and medical fields and their threats to society were expressed with some examples. Instances of the astrological activities within higher education institutions, such as an astrology-based master degree thesis, the astrology certificate programs, and an astrology column in an official medical school magazine were evaluated, and it was put forward that they contributed to increase the level of threat and it was also claimed that the existence of astrological activities in the universities contradicts the main purpose and principles of the higher education. In conclusion, some regulatory actions like the implementation of the scientific literacy and demarcation problem to each level of educational curriculum, a general policy for excluding the pseudoscience from higher education institutions and a recommended health warning at the top of the astrology were suggested.

    Full Text Available Approximately one million international students were enrolled at U.S. universities in the academic year 2015–2016, and the number has been steadily rising since. Although these students aim to increase intercultural communication skills, international knowledge, and critical thinking skills, some international students experience difficulty participating in class discussion. Several studies have revealed a range of obstacles to full participation in in-class discussions, including language, cultural differences, academic differences, and social isolation. Among these barriers, some studies have identified emotional factors that significantly affect learning. This study was an in-depth exploration of the adverse emotional factors that impede discussion participation. Using a qualitative approach, twenty-three international students at one university were interviewed, and their responses analyzed. Students reported that fear, embarrassment, social isolation, judgment and discrimination were barriers to participation. These findings are discussed in the context of a framework for reducing negative emotional states, employing self-efficacy theory. This framework was applied to the interview results and the author’s observation of international students’ behavior in dormitories and university offices. These findings suggest a possible intervention approach for educators to help international students express themselves in the classroom.

  18. Managing Active Learning Processes in Large First Year Physics Classes: The Advantages of an Integrated Approach

    Full Text Available Turning lectures into interactive, student-led question and answer sessions is known to increase learning, but enabling interaction in a large class seems aninsurmountable task. This can discourage adoption of this new approach – who has time to individualize responses, address questions from over 200 students and encourage active participation in class? An approach adopted by a teaching team in large first-year classes at a research-intensive university appears to provide a means to do so. We describe the implementation of active learning strategies in a large first-year undergraduate physics unit of study, replacing traditional, content-heavy lectures with an integrated approach to question-driven learning. A key feature of our approach is that it facilitates intensive in-class discussions by requiring students to engage in preparatory reading and answer short written quizzes before every class. The lecturer uses software to rapidly analyze the student responses and identify the main issues faced by the students before the start of each class. We report the success of the integration of student preparation with this analysis and feedback framework, and the impact on the in-class discussions. We also address some of the difficulties commonly experienced by staff preparing for active learning classes.

  19. Assessment of regulatory effectiveness. Peer discussions on regulatory practices

    International Nuclear Information System (INIS)

    1999-09-01

    This report arises from the seventh series of peer discussions on regulatory practices entitled 'Assessment of Regulatory Effectiveness'. The term 'regulatory effectiveness' covers the quality of the work and level of performance of a regulatory body. In this sense, regulatory effectiveness applies to regulatory body activities aimed at preventing safety degradation and ensuring that an acceptable level of safety is being maintained by the regulated operating organizations. In addition, regulatory effectiveness encompasses the promotion of safety improvements, the timely and cost effective performance of regulatory functions in a manner which ensures the confidence of the operating organizations, the general public and the government, and striving for continuous improvements to performance. Senior regulators from 22 Member States participated in two peer group discussions during March and May 1999. The discussions were focused on the elements of an effective regulatory body, possible indicators of regulatory effectiveness and its assessment. This report presents the outcome of these meetings and recommendations of good practices identified by senior regulators, which do not necessarily reflect those of the governments of the nominating Member States, the organizations they belong to, or the International Atomic Energy Agency. In order to protect people and the environment from hazards associated with nuclear facilities, the main objective of a nuclear regulatory body is to ensure that a high level of safety in the nuclear activities under its jurisdiction is achieved, maintained and within the control of operating organizations. Even if it is possible to directly judge objective safety levels at nuclear facilities, such safety levels would not provide an exclusive indicator of regulatory effectiveness. The way the regulatory body ensures the safety of workers and the public and the way it discharges its responsibilities also determine its effectiveness. Hence the

    Biologic measurements can furnish two kinds of information: measure of the individual worker's overall exposure; and measure of the worker's individual and characteristic response. Measurement of exposure may be made by: determining in blood, urine, hair, nails, other body fluids, and body tissues, the amount of substance to which the worker was exposed; by determining the amount of metabolite(s) of the substance in tissues and fluids; and by determining the amount of the substance in the exhaled breath. Measurements of response give an estimate of the physiologic status of the worker and may measure: changes in amount of some critical biochemical constituent; changes in activity of a critical enzyme; and changes in some physiologic function. Two schools of thought regarding biologic limit values or biological threshold limit values for hazardous materials are discussed

    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.

    resistance and high temperature operation over Si devices have aided in the paradigm shift towards wide bandgap devices. The low gate charge requirements of SiC MOSFETs enables use of these devices in radio frequency (RF) converters using resonant topologies operating at MHz frequency range. The RF...... are not commercially available and power modules have to be custom designed for these applications. This work demonstrates performance of various commercial MOSFET packages at frequency of 2.56 MHz.

    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.

  4. A taxonomy and discussion of software attack technologies

    Software is a complex thing. It is not an engineering artifact that springs forth from a design by simply following software coding rules; creativity and the human element are at the heart of the process. Software development is part science, part art, and part craft. Design, architecture, and coding are equally important activities and in each of these activities, errors may be introduced that lead to security vulnerabilities. Therefore, inevitably, errors enter into the code. Some of these errors are discovered during testing; however, some are not. The best way to find security errors, whether they are introduced as part of the architecture development effort or coding effort, is to automate the security testing process to the maximum extent possible and add this class of tools to the tools available, which aids in the compilation process, testing, test analysis, and software distribution. Recent technological advances, improvements in computer-generated forces (CGFs), and results in research in information assurance and software protection indicate that we can build a semi-intelligent software security testing tool. However, before we can undertake the security testing automation effort, we must understand the scope of the required testing, the security failures that need to be uncovered during testing, and the characteristics of the failures. Therefore, we undertook the research reported in the paper, which is the development of a taxonomy and a discussion of software attacks generated from the point of view of the security tester with the goal of using the taxonomy to guide the development of the knowledge base for the automated security testing tool. The representation for attacks and threat cases yielded by this research captures the strategies, tactics, and other considerations that come into play during the planning and execution of attacks upon application software. The paper is organized as follows. Section one contains an introduction to our research

    In this large cross-sectional study, we aimed to analyze growth trends in white subjects with Class III malocclusion using both skeletal and dental maturation staging. The sample consisted of 1091 pretreatment lateral cephalometric records of Class III patients (560 female, 531 male). Cephalometric dentoskeletal measurements were compared at subsequent stages in cervical vertebral maturation and Hellman's categorization of dental development by means of ANOVA with Bonferroni post-hoc tests in both sexes separately. The findings indicated that, in Class III malocclusion, the pubertal peak in mandibular growth occurs between stages 3 and 4 of cervical vertebral maturation, with average increases in total mandibular length of about 8 and 5.5 mm in Class III boys and girls, respectively. Significant changes in total mandibular length occur until young adulthood (18 years on average), with increases between late maturation stages (4 through 6) that were twice as large as in subjects with normal occlusion for the Class III females, and 3 times as large as in subjects with normal occlusion for the Class III males. Growth trends toward accentuated Class III profile and increased vertical dimension of the face also become apparent at late developmental stages (corresponding with complete eruption of the second and third molars).

    Human tumors exhibit increased glucose uptake and metabolism as a result of high demand for ATP and anabolic substrates and this metabolotype is a negative prognostic indicator for survival. Recent studies have demonstrated that cancer cells from several tissue origins and genetic backgrounds require the expression of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 4 (PFKFB4), a regulatory enzyme that synthesizes an allosteric activator of glycolysis, fructose-2,6-bisphosphate. We report the discovery of a first-in-class PFKFB4 inhibitor, 5-(n-(8-methoxy-4-quinolyl)amino)pentyl nitrate (5MPN), using structure-based virtual computational screening. We find that 5MPN is a selective inhibitor of PFKFB4 that suppresses the glycolysis and proliferation of multiple human cancer cell lines but not non-transformed epithelial cells in vitro. Importantly, 5MPN has high oral bioavailability and per os administration of a non-toxic dose of 5MPN suppresses the glucose metabolism and growth of tumors in mice.

    2013-08-01

    For more than a decade, industry analysts and policy makers have raised concerns about declining pharmaceutical innovation, citing declining numbers of new molecular entities (NMEs) approved in the United States each year. Yet there is little consensus on whether this is the best measure of "innovation." We examined NME approvals during 1987-2011 and propose the three distinct subcategories of NMEs--first-in-class, advance-in-class, and addition-to-class--to provide more nuanced and informative insights into underlying trends. We found that trends in NME approvals were largely driven by addition-to-class, or "me too," drug approvals, while first-in-class approvals remained fairly steady over the study period. Moreover, the higher proportion of first-in-class drug approvals over the most recent decade is an encouraging sign of the health of the industry as a whole.

    In this paper, we describe our recent approaches to introducing students in a beginning computer science class to the study of ethical issues related to computer science and technology. This consists of three components: lectures on ethics and technology, in-class discussion of ethical scenarios, and a reflective paper on a topic related to ethics or the impact of technology on society. We give both student reactions to these aspects, and instructor perspective on the difficulties and benefits in exposing students to these ideas.

    To study the adverse effects of sleep problems and sleep insufficiency on attention in class and pupils' acadamic achievements. A total of 1138 students from four primary schools at ages of 6-12 years were randomly sampled from four districts of Changsha city, Hunan Province June 2009 to April 2010. The inquired items included sleep problems, sleep time, sleep quality, attention in class and academic achievements. Teachers and parents observed the pupils according to the unified requirements for 3 months and then filled out the questionnaires. The total valid inquiry tables were 1091 with the answering rate of 95.87%, including 549 boys and 542 girls. The sleep quality was more poor in children with sleep problems or sleep insufficiency than in children with normal sleep. The sleep quality was reduced and aggravated along with the increasing sleep problems and the reducing sleep time. The attention in class and academic achievements in children with sleep problems or sleep insufficiency were more poor than in children with normal sleep. The sleep quality index was negatively correlated with attention in class and academic achievements. The attention in class was positively correlated with academic achievements. The decline in sleep quality directly affects the attention in class and reduce the academic achievements in primary school children.

    After more than half a century of intense efforts, the development of exoskeleton has seen major advances, and several remarkable achievements have been made. Reviews of developing history of exoskeleton are presented, both in active and passive categories. Major models are introduced, and typical technologies are commented on. Difficulties in control algorithm, driver system, power source, and man-machine interface are discussed. Current researching routes and major developing methods are mapped and critically analyzed, and in the process, some key problems are revealed. First, the exoskeleton is totally different from biped robot, and relative studies based on the robot technologies are considerably incorrect. Second, biomechanical studies are only used to track the motion of the human body, the interaction between human and machines are seldom studied. Third, the traditional developing ways which focused on servo-controlling have inborn deficiency from making portable systems. Research attention should be shifted to the human side of the coupling system, and the human ability to learn and adapt should play a more significant role in the control algorithms. Having summarized the major difficulties, possible future works are discussed. It is argued that, since a distinct boundary cannot be drawn in such strong-coupling human-exoskeleton system, the more complex the control system gets, the more difficult it is for the user to learn to use. It is suggested that the exoskeleton should be treated as a simple wearable tool, and downgrading its automatic level may be a change toward a brighter research outlook. This effort at simplification is definitely not easy, as it necessitates theoretical supports from fields such as biomechanics, ergonomics, and bionics.

  13. Discussion of thermal extraction chamber concepts for Lunar ISRU

    Pfeiffer, Matthias; Hager, Philipp; Parzinger, Stephan; Dirlich, Thomas; Spinnler, Markus; Sattelmayer, Thomas; Walter, Ulrich

    The Exploration group of the Institute of Astronautics (LRT) of the Technische Universitüt a München focuses on long-term scenarios and sustainable human presence in space. One of the enabling technologies in this long-term perspective is in-situ resource utilization (ISRU). When dealing with the prospect of future manned missions to Moon and Mars the use of ISRU seems useful and intended. The activities presented in this paper focus on Lunar ISRU. This basically incorporates both the exploitation of Lunar oxygen from natural rock and the extraction of solar wind implanted particles (SWIP) from regolith dust. Presently the group at the LRT is examining possibilities for the extraction of SWIPs, which may provide several gaseous components (such as H2 and N2) valuable to a human presence on the Moon. As a major stepping stone in the near future a Lunar demonstrator/ verification experiment payload is being designed. This experiment, LUISE (LUnar ISru Experiment), will comprise a thermal process chamber for heating regolith dust (grain size below 500m), a solar thermal power supply, a sample distribution unit and a trace gas analysis. The first project stage includes the detailed design and analysis of the extraction chamber concepts and the thermal process involved in the removal of SWIP from Lunar Regolith dust. The technique of extracting Solar Wind volatiles from Regolith has been outlined by several sources. Heating the material to a threshold value seems to be the most reasonable approach. The present paper will give an overview over concepts for thermal extraction chambers to be used in the LUISE project and evaluate in detail the pros and cons of each concept. The special boundary conditions set by solar thermal heating of the chambers as well as the material properties of Regolith in a Lunar environment will be discussed. Both greatly influence the design of the extraction chamber. The performance of the chamber concepts is discussed with respect to the

    Full Text Available In class of Phonetic phonology, students having confusion about a huge differences of each symbol and its phoneme between Indonesia and English. Only by giving them a lecturer in each meeting would not satisfy their needs. As it simply cannot keep up with it, learners have to be able to process and investigate their curiosity on their own autonomously.  Oral presentation is believed as one of implementations to promote learner autonomy in University environment. 32 students in the class divided into 10 groups presented several topics about phonetic and phonology. The data were collected through observation, interview, and questionaire. Then, they were analyzed using the steps in case study research method. The finding shows that oral presentation had given them “freedom”to discover and autonomy to do their own learning. They also given good response relating of  what they had learnt dan investigated during teaching learning in Phonetic and Phonology Class.

    2014-10-15

    Full text: Many apparatus today are complicated in that they consist of many components. The risk associated with these complicated apparatus is a product of their unreliable system components and sub-components. The components are a collection of inter-related individual components/ sub-components that can be correlated in a direct cause and effect manner and thus failures can be historically retraced or predicted. Once the confines of the complicated apparatus is extended to include such inputs as humans operating the equipment, man-machine interfaces, multiple processes surrounding the operation of the apparatus, etc., the whole system becomes complex. Complex systems are based on interdependencies versus dependencies, and risk becomes a product of improperly aligned or poorly integrated activities. Cause and effect becomes more loosely coupled and both path and circumstance dependent. To better understand and improve our defence in depth strategies we need to better understand and discuss complex systems and hence allow better erection of protective barriers. (author)

  9. Severe accidents and operator training - discussion of potential issues

    International Nuclear Information System (INIS)

    Vidard, Michel

    1997-01-01

    R and D programs developed throughout the world allowed significant progress in the understanding of physical phenomena and Severe Accident Management (SAM) programs started in many OECD countries. Basically, the common denominator to all these SAM programs was to provide utility operators with procedures or guidelines allowing to deal with complex situations not formally considered in the Design Basis, including accidents where a significant portion of the core had molten. These SAM procedures or guidelines complement the traditional accident management procedures (event, symptom or physical-state oriented) and should allow operators to deal with a reasonably bounding set of situations. Dealing with operator or crisis team training, it was recognized that training would be beneficial but that training programs were lagging, i.e. though training sessions were either organized or contemplated after implementation of SAM programs, they seemed to be somewhat different from more traditional training sessions on Accident Management. After some explanations on the differences between Design Basis Accidents (DBAs) and Beyond Design Basis Accidents (BDBAs), this paper underlines some potential difficulties for training operators and discuss problems to be addressed by organisms contemplating SAM training sessions consistent with similar activities for less complex events

    Philosophy of science offers a rich lineage of analysis concerning the nature of scientific explanation, but the vast majority of this work, aiming to provide an analysis of the relation that binds a given explanans to its corresponding explanandum, presumes the proper analytic focus rests at the level of individual explanations. There are, however, other questions we could ask about explanation in science, such as: What role(s) does explanatory practice play in science? Shifting focus away from explanations, as achievements, toward explaining, as a coordinated activity of communities, the functional perspective aims to reveal how the practice of explanatory discourse functions within scientific communities given their more comprehensive aims and practices. In this paper, I outline the functional perspective, argue that taking the functional perspective can reveal important methodological roles for explanation in science, and consequently, that beginning here provides resources for developing more adequate responses to traditional concerns. In particular, through an examination of the ideal gas law, I emphasize the normative status of explanations within scientific communities and discuss how such status underwrites a compelling rationale for explanatory power as a theoretical virtue.

  11. Science and Faith: Discussing Astronomy Research with Religious Audiences

    Koekemoer, Anton M.

    2006-12-01

    An important component of our outreach as research astronomers involves interaction with the religious community. From my personal perspective, being an active research astronomer who is also a practicing Christian, I am sometimes invited to present the latest astronomical research to church audiences and other religious groups; belonging to both communities thereby provides a valuable means of contributing to the dialogue between science and religion. These opportunities can be used to explain that science and religion are not necessarily in conflict but can be considered to be quite complementary. For instance, an important aspect of religion deals with the purpose of our existence, while science is more focussed on providing physical explanations for what we observe in the world, using a well-defined scientific process. Hence, religious believers need not necessarily abandon their faith in order to accept mainstream scientific research; these address very different and complementary aspects of our existence. Recent ideas such as Intelligent Design attempt to address the scientific method, but do not address the ultimate religious question of purpose and do not contribute towards reconciling science and religion in this sense. Ultimately, every individual arrives at their own understanding of this rather complex interplay; I will present some personal reflections on general approaches for discussing mainstream astronomical research with religious audiences, aimed at helping to advance the dialogue between religion and science in general.

  12. Effectiveness of Using Online Discussion Forum for Case Study Analysis

    Full Text Available Business schools are exploring new pedagogical approaches to learning in order to deal with challenges such as increased class sizes, limited funding support, and difficulties in facilitating and encouraging active participation and learning among a diverse cohort of students. This paper reports on a study of the effectiveness of a pedagogical approach that blends online discussion board and case study. Analysing quantity and quality of online postings and comparing accounting students’ performance with previous cohort, this study observes a significant improvement in student learning. Appropriate design and delivery strategies and clear assessment criteria for assessment and use have provided an effective learning vehicle for students, helped them overcome their own language related barriers, and encouraged them to participate in a nonthreatening environment. This approach further complemented the benefits of peer-to-peer learning and case study pedagogy. Reported increase in workload for students and marking load for academics and measuring the value of learning, however, are some of the challenges that need further attention by researchers.

  13. Discussion of OECD LWR Uncertainty Analysis in Modelling Benchmark

    2013-01-01

    The demand for best estimate calculations in nuclear reactor design and safety evaluations has increased in recent years. Uncertainty quantification has been highlighted as part of the best estimate calculations. The modelling aspects of uncertainty and sensitivity analysis are to be further developed and validated on scientific grounds in support of their performance and application to multi-physics reactor simulations. The Organization for Economic Co-operation and Development (OECD) / Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC) has endorsed the creation of an Expert Group on Uncertainty Analysis in Modelling (EGUAM). Within the framework of activities of EGUAM/NSC the OECD/NEA initiated the Benchmark for Uncertainty Analysis in Modelling for Design, Operation, and Safety Analysis of Light Water Reactor (OECD LWR UAM benchmark). The general objective of the benchmark is to propagate the predictive uncertainties of code results through complex coupled multi-physics and multi-scale simulations. The benchmark is divided into three phases with Phase I highlighting the uncertainty propagation in stand-alone neutronics calculations, while Phase II and III are focused on uncertainty analysis of reactor core and system respectively. This paper discusses the progress made in Phase I calculations, the Specifications for Phase II and the incoming challenges in defining Phase 3 exercises. The challenges of applying uncertainty quantification to complex code systems, in particular the time-dependent coupled physics models are the large computational burden and the utilization of non-linear models (expected due to the physics coupling).

  14. Occlusal stability in Class II, Division 1, deep bite cases followed up for many years after orthodontic treatment.

    1998-12-01

    This case report analyzes long-term occlusal stability that can be achieved in Class II, Division 1, deep bite cases with active treatment finished during the period of maxillomandibular growth. The analysis was designed to identify occlusal features common to two cases at the end of active treatment and to study how the occlusion changed with growth and jaw movement to achieve stability. The following occlusal features were shared by the two cases at the end of active treatment: (1) AB plane and axes of the maxillary and mandibular posterior teeth were perpendicular to functional occlusal plane; (2) the axis of the lower incisor was almost perpendicular to DC-L1i line; (3) the anterior occlusion was overcorrected to or near an edge-to-edge relationship. Items 1 and 2 remained unchanged throughout the follow-up periods, regardless of growth status, and the overjet and overbite increased during maxillomandibular growth after treatment. During the period of mandibular growth alone, after the end of retention, the axes of maxillary incisors tipped labially; as a result, F line became parallel to CDM line by the end of growth. The labial tipping of maxillary incisors brought the lower incisal edge into contact with or extremely near the inflection point (Bp).1 By the end of growth, the tangent of Bp became parallel to or coincident with DC-L1i line and perpendicular to the axis of the lower incisor, and the DC-L1i lines at various times posttreatment were almost parallel to each other in the two cases. Overjet increased as the maxillary incisors tipped labially, providing proper protrusive and retrusive paths for mandibular guidance. The angle between the functional occlusal plane and CDM line stayed almost the same as at the end of active treatment in the two cases, suggesting a possible change in the angle of eminence in harmony with the functional occlusal plane. These factors apparently contributed to the long-term occlusal stability in the two cases.

    With the rapid development of online communities, mining and extracting quality knowledge from online discussions becomes very important for the industrial and marketing sector, as well as for e-commerce applications and government. Most of the existing techniques model a discussion as a social network of users represented by a user-based graph without considering the content of the discussion. In this paper we propose a new multilayered mode to analysis online discussions. The user-based and message-based representation is combined in this model. A novel frequent concept sets based clustering method is used to cluster the original online discussion network into topic space. Domain ontology is used to improve the clustering accuracy. Parallel methods are also used to make the algorithms scalable to very large data sets. Our experimental study shows that the model and algorithms are effective when analyzing large scale online discussion data.

  17. Risk perception and benefits perception. Survey results and discussion

    The fact that the risks deriving from different activities involving the same radiation exposure are seen very differently by a single population is a highly significant one. Exactly identical risks are considered oppositely, depending on the origin of radiation (whether produced by medical applications or by nuclear power plants, resulting from natural radiation or from artificial radiation). It appears as if there was good radiation and bad radiation..! One of the purposes of the paper is the discussion of causes. The acceptance of a given risk by a certain section of the population is closely related to the benefits that the group expects to receive-either consciously or unconsciously-from the activity producing the risk. Consequently, an analysis of the factors influencing the eventual rejection of a practice should explore not only fears, but also hopes...! On the basis of a risk-perception survey carried out in a population sector attending hospitals-including both patients and physicians-, a prior objective analysis of the results obtained was performed and, later on, the various statements by those surveyed were studied. The design of the survey allowed for a comparative assessment of the perception of different risks depending on the people's educational and social level. An epistemological study was made on the validity involved in the use of the data resulting from the survey, so as to reach different conclusions. The population's opinion about the capacity for response, the qualification and the mitigation means available to the State authorities in order to face an eventual radiological emergency plays a leading role in risk perception. In an analysis of the relevant factors involved in risk and benefits perception by the population (in the real world), attention must be paid to the existence of organized opinion groups representing the interest of a given sector. Of course, the population's confidence in the experts providing the information is a key

  18. Optimized Design and Discussion on Middle and Large CANDLE Reactors

    2012-08-01

    Full Text Available CANDLE (Constant Axial shape of Neutron flux, nuclide number densities and power shape During Life of Energy producing reactor reactors have been intensively researched in the last decades [1–6]. Research shows that this kind of reactor is highly economical, safe and efficiently saves resources, thus extending large scale fission nuclear energy utilization for thousands of years, benefitting the whole of society. For many developing countries with a large population and high energy demands, such as China and India, middle (1000 MWth and large (2000 MWth CANDLE fast reactors are obviously more suitable than small reactors [2]. In this paper, the middle and large CANDLE reactors are investigated with U-Pu and combined ThU-UPu fuel cycles, aiming to utilize the abundant thorium resources and optimize the radial power distribution. To achieve these design purposes, the present designs were utilized, simply dividing the core into two fuel regions in the radial direction. The less active fuel, such as thorium or natural uranium, was loaded in the inner core region and the fuel with low-level enrichment, e.g. 2.0% enriched uranium, was loaded in the outer core region. By this simple core configuration and fuel setting, rather than using a complicated method, we can obtain the desired middle and large CANDLE fast cores with reasonable core geometry and thermal hydraulic parameters that perform safely and economically; as is to be expected from CANDLE. To assist in understanding the CANDLE reactor’s attributes, analysis and discussion of the calculation results achieved are provided.

    Screening mammography for younger women and prostate-specific antigen (PSA) measurement have controversial benefits and known potential adverse consequences. While providing informed consent and eliciting patient preference have been advocated for these tests, little is known about how often these discussions take place or about barriers to these discussions. We administered a survey to medical house staff and attending physicians practicing primary care. The survey examined physicians' likelihood of discussing screening mammography and PSA testing, and factors influencing the frequency and quality of these discussions. For the three scenarios, 16% to 34% of physicians stated that they do not discuss the screening tests. The likelihood of having a discussion was significantly associated with house staff physicians' belief that PSA screening is advantageous; house staff and attending physicians' intention to order a PSA test, and attending physicians' intention to order a mammogram; and a controversial indication for screening. The most commonly identified barriers to discussions were lack of time, the complexity of the topic, and a language barrier. Physicians report they often do not discuss cancer screening tests with their patients. Our finding that physicians' beliefs and intention to order the tests, and extraneous factors such as time constraints and a language barrier, are associated with discussions indicates that some patients may be inappropriately denied the opportunity to choose whether to screen for breast and prostate cancer.

    To examine the separation of the pterygomaxillary region at the posterior nasal spine level after Le Fort I osteotomy in Class III patients. The study group consisted of 37 Japanese patients with mandibular prognathism and asymmetry, with maxillary retrognathism or asymmetry. A total of 74 sides were examined. Le Fort I osteotomy was performed without a pterygoid osteotome, with an ultrasonic curette used to remove interference at the pterygomaxillary region. Postoperative computed tomography (CT) was analyzed for all patients. The separation of the pterygomaxillary region and the location of the descending palatine artery were assessed. Although acceptable separation between the maxilla and pterygoid plates was achieved in all patients, an exact separation of the pterygomaxillary junction at the posterior nasal spine level was found in only 18 of 74 sides (24%). In 29 of 74 sides (39.2%), the separation occurred anterior to the descending palatine artery. In 29 of 74 sides (39.2%), complete separation between the maxilla and lateral and/or medial pterygoid plate was not achieved, but lower level separation of the maxilla and pterygoid plate was always complete. The maxillary segments could be moved to the postoperative ideal position in all cases. Le Fort I osteotomy without an osteotome does not always induce an exact separation at the pterygomaxillary junction at the posterior nasal spine level, but the ultrasonic bone curette can remove the interference between maxillary segment and pterygoid plates more safely.

  3. RateMyProfessors.com versus formal in-class student evaluations of teaching

    2007-05-01

    Full Text Available Using data for 426 instructors at the University of Maine, we examined the relationship between RateMyProfessors.com (RMP indices and formal in-class student evaluations of teaching (SET. The two primary RMP indices correlate substantively and significantly with their respective SET items: RMP overall quality correlates r = .68 with SET item, Overall, how would you rate the instructor?; and RMP ease correlates r = .44 with SET item, How did the work load for this course compare to that of others of equal credit? Further, RMP overall quality and RMP ease each correlates with its corresponding SET factor derived from a principal components analysis of all 29 SET items: r = .57 and .51, respectively. While these RMP/SET correlations should give pause to those who are inclined to dismiss RMP indices as meaningless, the amount of variance left unexplained in SET criteria limits the utility of RMP. The ultimate implication of our results, we believe, is that higher education institutions should make their SET data publicly available online.

    Online learning formats are prevalent in current higher education. Given the changing student demographics and the drive for creativity in educating a technology-savvy student, it is imperative to incorporate innovative and alternative learning modalities to engage these students. This pilot study was designed as a quality improvement program evaluation comparing the effects of an online learning module with traditional classroom delivery of transcultural nursing content using a posttest two-group survey design in associate degree nursing students. The students' perceived knowledge and confidence were investigated after receiving the lecture for both the online and in-class groups. Data analysis revealed the online cohort perceived themselves as more knowledgeable concerning the ways that cultural factors influence nursing care, but not more confident in providing culturally competent care. Due to the students' perceived knowledge gain, this pilot study supports the use of online learning modules as being more effective than the traditional classroom delivery of transcultural nursing content.

    2009-04-01

    Our aim in this study was to investigate the position of the glenoid fossa in subjects with Class III malocclusion associated with mandibular protrusion to better clarify the role of this craniofacial component in Class III skeletal disharmony. A sample of 30 subjects, aged 8 years +/- 6 months, with skeletal and dental Class III malocclusion associated with mandibular protrusion, normal skeletal vertical relationships, and normal mandibular dimensions, was compared with a control group of 33 subjects with skeletal and dental Class I relationships. The comparisons between the Class III group and the control group on the cephalometric measures for the assessment of glenoid fossa position were performed with the Mann-Whitney U test at P <0.05. Subjects with Class III malocclusion had a significantly more mesial position of the glenoid fossa, when compared with the control group as measured with 3 parameters. An anterior position of the glenoid fossa is a possible diagnostic anatomic feature of Class III malocclusion associated with mandibular protrusion. An effective measurement to evaluate glenoid fossa position in craniofacial relationships is the cephalometric distance from the glenoid fossa to the frontomaxillary-nasal suture.

    Our aim in this study was to evaluate the prevalence of temporomandibular disorders (TMD) in Class III patients treated with mandibular cervical headgear (MCH) and fixed appliances. The sample of 75 patients included 25 patients with no previous orthodontic treatment, 25 Class I patients who had undergone orthodontic treatment with fixed appliances and without extractions, and 25 patients with dentoskeletal Class III disharmonies treated with MCH and fixed appliances. The Helkimo index was used to test the prevalence of TMD symptoms in the 3 groups. The prevalence rates of the Helkimo index in the 3 groups were compared with the z score on proportions. No statistically significant differences in the prevalence rates of the Helkimo index scores in the 3 groups were found (P = .367). Most subjects in the 3 groups had an Helkimo index of zero (66.7%). Subjects with Class III malocclusions treated with MCH and fixed appliances do not have greater prevalence of TMD symptoms than do Class I subjects treated with fixed appliances or untreated subjects.

    Full Text Available Objectives The purpose of this study was to evaluate the microleakage of 4 temporary materials in teeth with Class II-type endodontic access preparations by using a glucose penetration model. Materials and Methods Glucose reaction test was performed to rule out the presence of any reaction between glucose and temporary material. Class II-type endodontic access preparations were made in extracted human premolars with a single root (n = 10. Each experimental group was restored with Caviton (GC, Spacer (Vericom, IRM (Dentsply-Caulk, or Fuji II(GC. Microleakage of four materials used as temporary restorative materials was evaluated by using a glucose penetration model. Data were analyzed by the one-way analysis of variance followed by a multiple-comparison Tukey test. The interface between materials and tooth were examined under a scanning electron microscope (SEM. Results There was no significant reaction between glucose and temporary materials used in this study. Microleakage was significantly lower for Caviton and Spacer than for Fuji II and IRM. SEM observation showed more intimate adaptation of tooth-restoration interfaces in Caviton and Spacer than in IRM and Fuji II. Conclusions Compared to IRM and Fuji II, Caviton and Spacer can be considered better temporary sealing materials in Class II-type endodontic access cavities.

    Norms and guidelines are formed for safe disposal of hospital waste but question is whether these guidelines are being followed and if so, to what extent. Hence, this study was conducted with objective to study the knowledge and practices about hospital waste disposal and universal safety precautions in class IV employee and to study its relationship with education, occupation and training. A cross-sectional study was carried out in a teaching hospital in Mumbai using semi-structured questionnaire in which Class IV employee were included. Questionnaire was filled by face to face interview. Data were analyzed using SPSS. 48.7% Class IV employee were not trained. More than 40% were following correct practices about disinfection of infectious waste. None of the respondents were using protective footwear while handling hospital waste. Only 25.5% were vaccinated for hepatitis B. 16% had done HIV testing due to contact with blood, body fluid, needle stick injury. Knowledge and practices about hospital waste disposal and universal precaution were statistically significant in trained respondents. Training of employees should be given top priority; those already in service should be given on the job training at the earliest.

    1979-01-01

    Recovery from X-ray-induced damage in class B oocytes of Drosophila melanogaster was studied by the dose-fractionation technique. A total dose of 5000 R was delivered either as a single exposure or as two fractions of 2000 R and 3000 R separated by increasing time intervals. The use of attached-X females made it possible to study simultaneously the induction of dominant lethals and of chromosome aberrations (detachments of the attached-X chromosome). The same repair kinetics were observed for sublethal damage and for the lesions leading to detachments. The time-response curves were of similar shape: a plateau was reached within 20 to 30 min and half of the repairable damage disappeared in 5 to 7 min. It is concluded that the same type of X-ray-induced primary lesion in chromosomes is responsible for the induction of detachments and for dominant lethals. As primary lesions actual chromosome breaks or lesions leading to breaks and chromosome rearrangements are assumed. (author)

  11. Importance and difficulties of cooperative learning application in class teaching from teachers' perspective

    2016-01-01

    Full Text Available Based on previous knowledge of cooperative learning two approaches stand out in researching the importance of cooperative learning: a the first approach tries to examine the effects, conditions and mechanisms by which educational outcomes are realized in the application of cooperative learning; and b the second approach moves the focus towards attitudes and perceptions of teachers and students on the relevance of cooperative learning. By applying descriptive-analytical technique we conducted a research aimed at examining the opinions of teachers (N=305 about the importance and difficulties in application of cooperative learning in the context of class teaching. The results show that the teachers had positive attitudes towards the importance of cooperative learning for reaching various educational goals and socio-affective and cognitive development of students. It turned out that the opinions of the teachers were not determined by the level of their education or work experience. Additionally, it turned out that the teachers' opinions about the difficulties of application in class are due more to work organization and were not assessed from the aspect of knowledge, attitudes and convictions of the participants in the teaching process. The obtained results, although generally encouraging for teaching practice indicate a need for further advancement of this segment of the teacher's work in order to understand better the value of cooperative learning and consider more critically the difficulties for its application in classroom.

    2005-10-01

    The Internet is an innovative strategy to increase public participation. It is important to include pregnant and parenting teens' perspectives when planning programs to meet their needs. This qualitative study explored online discussions as a strategy to enhance participation by this population. Findings showed that online communication was preferred over face-to-face group discussions. Being anonymous online encouraged open and honest feedback. Participants experienced various forms of social support, however, there was an overall lack of teen involvement online. Strategies to engage adolescents in online discussions and reduce barriers are discussed. Strategies included the use of teen moderators, home computer access, technical support, and engagement in naturally flowing online discussions to meet social support needs. Blending researchers' with teens' needs for social support in an online environment is encouraged. With careful planning and design, online communications can result in mutual benefits for researchers, service providers, and pregnant and parenting adolescents.

  14. Examining how discussing underrepresentation may mediate female engagement in physics

    Science.gov (United States)

    Lock, Robynne M.; Tompkins, Reganne; Hazari, Zahra

    2013-04-01

    Despite the large number of female students taking high school physics, only about a fifth of physics bachelor's degrees are awarded to women. In a previous study, we tested five factors commonly proposed to positively impact female students' choice of a physical science career using multivariate matching methods on national survey data. Four of these factors (having a single-sex class, having female scientist guest speakers, having a female physics teacher, and discussing the work of female scientists) were found to have no effect. The only factor found to have a positive effect was the explicit discussion of the underrepresentation of women in physics. In order to explore this further, a case study of the classes of one teacher reported to discuss the underrepresentation of women was conducted. Two classroom underrepresentation discussions were recorded, students and teacher were interviewed, and relevant student work was collected. Analyzing the case study data, we report on how discussing underrepresentation may mediate female engagement in physics.

    Aird, H. M.

    2015-12-01

    An interdisciplinary active learning course was introduced at the University of Puget Sound entitled 'Mineral Resources and the Environment'. Various formative assessment and active learning techniques that have been effective in other courses were adapted and implemented to improve student learning, increase retention and broaden knowledge and understanding of course material. This was an elective course targeted towards upper-level undergraduate geology and environmental majors. The course provided an introduction to the mineral resources industry, discussing geological, environmental, societal and economic aspects, legislation and the processes involved in exploration, extraction, processing, reclamation/remediation and recycling of products. Lectures and associated weekly labs were linked in subject matter; relevant readings from the recent scientific literature were assigned and discussed in the second lecture of the week. Peer-based learning was facilitated through weekly reading assignments with peer-led discussions and through group research projects, in addition to in-class exercises such as debates. Writing and research skills were developed through student groups designing, carrying out and reporting on their own semester-long research projects around the lasting effects of the historical Ruston Smelter on the biology and water systems of Tacoma. The writing of their mini grant proposals and final project reports was carried out in stages to allow for feedback before the deadline. Speakers from industry were invited to share their specialist knowledge as guest lecturers, and students were encouraged to interact with them, with a view to employment opportunities. Formative assessment techniques included jigsaw exercises, gallery walks, placemat surveys, think pair share and take-home point summaries. Summative assessment included discussion leadership, exams, homeworks, group projects, in-class exercises, field trips, and pre-discussion reading exercises

    1980-01-01

    A discussion of the lung cancer risk associated with radon exposure inside dwellings is presented. The risk factors found for miners are discussed and modified according to the lower mean breathing rates inside dwellings and the differences in atmosphere. Statistical information on the lung cancer incidence in the Norwegian population indicates that a 'doubling exposure rate' of radon daughters inside dwellings may be about 2-3 WLM/yr. This corresponds to a radon concentration of about 10-15 pCi/l. These values are used in a discussion of the consequences of a future reduction of the mean ventilation rates in modern houses.

    The purpose of this student annual meeting is to address topics that are becoming more relevant to medical physicists, but are not frequently addressed, especially for students and trainees just entering the field. The talk is divided into two parts: medical billing and regulations. Hsinshun Wu – Why should we learn radiation oncology billing? Many medical physicists do not like to be involved with medical billing or coding during their career. They believe billing is not their responsibility and sometimes they even refuse to participate in the billing process if given the chance. This presentation will talk about a physicist’s long career and share his own experience that knowing medical billing is not only important and necessary for every young medical physicist, but that good billing knowledge could provide a valuable contribution to his/her medical physics development. Learning Objectives: The audience will learn the basic definition of Current Procedural Terminology (CPT) codes performed in a Radiation Oncology Department. Understand the differences between hospital coding and physician-based or freestanding coding. Apply proper CPT coding for each Radiation Oncology procedure. Each procedure with its specific CPT code will be discussed in detail. The talk will focus on the process of care and use of actual workflow to understand each CPT code.

    The world wide web opens up new opportunities to interconnect electronic and classroom teaching and to promote active student participation. In this project article we describe the use of internet discussion forums as part of a student-centred teaching concept of pharmacology and discuss its advantages and disadvantages based on evaluation data and current literature. Final year medical students at the Technische Universität München (Munich, Germany) with the elective pharmacology moderated an internet forum that allowed all students to discuss pharmacology-related questions. Evaluation results of forum participants and elective students demonstrated a learning benefit of internet forums in pharmacology teaching. Internet discussion forums offer an easy-to-implement and effective way to actively engage students and increase the learning benefit of electronic and classroom teaching in pharmacology.

  9. Architectural education online and in-class synergies: reshaping the course and the learner

    Directory of Open Access Journals (Sweden)

    Olga Ioannou

    2015-10-01

    Full Text Available Architectural courses have been traditionally planned in the context of a physical classroom where the direct rapport of the students with the instructor is an unswerving condition for learning. This model was formed, however, at a time when learning was not impacted by technology. Although digital media have infiltrated architectural practice, they still elude architectural design education. The author argues that the integration of online educational practices in architectural curricula can benefit design education immensely by raising interaction and making students assume responsibility for their learning. To demonstrate the gains of online and in-class synergy in architectural education a blended course was set up at the postgraduate program of the National Technical University of Athens, School of Architecture. Current trends of online learning were carefully examined in regard to their compatibility with the architectural design culture of “learning by doing”. The course was eventually founded on the core principles of the connectivist model where learning consists of the ability to construct and traverse networks of connections (Downes, 2012. This approach was chosen because of its affinity to the design praxis where similarly students are required to make critical connections in order to map spatial phenomena and reconstruct the real. Course content was redesigned to comply with its new medium. Students were offered multiple channels of communication. They were also asked to contribute to the content material. Course data analysis demonstrated an unprecedented level of participation, exchange and student satisfaction as expressed in the surveys that followed the course’s completion.

    Hauser, K.

    2002-01-01

    Open Spirit is the realization of a long sought after dream to create an open systems approach to G and G computing. The focus is on developing a plug-and-play, platform independent, vendor neutral application framework to enable workflow optimization for the oil and gas industry. Through Open Spirit, Oil and gas clients can either develop or purchase Open Spirit enabled applications and combine those applications together to optimize a particular workflow. Currently Open Spirit supports GeoQuest's Geo Frame and Landmark's Open Works project data stores. There are three primary benefits to using Open Spirit enabled applications. Users of Open Spirit enabled applications can access data from a variety of data sources without having to move or reformat the data. This reduces the time to get the information into the appropriate application and eliminates the need to have multiple copies of the same data, simplifying data management efforts. Second, Open Spirit bridges the gap between Unix and PC applications. Through Open Spirit, any applications developed for the NT platform can access information residing in a Unix project data store. Third, Open Spirit supports the concept of a virtual project set. A user can combine any number project data stores (GeoFrame, Open Works, Finder, RECALL and PDS/Tigress) and use the combined project sets as if they were a single project. The data is not moved, but instead accessed dynamically through Open Spirit from the appropriate native data store. Open Spirit allows interpreters to develop their own Best-in-Class workflow and to mix and match the applications they determine to be the best of their interpretation teams independent of vendor

    2016-07-01

    Full Text Available Background and Aims: Microleakage is one of the most common problems in bonding systems, which cause different clinical shortcomings such as post operative sensitivity, marginal discoloration and pulp necrosis that can decrease those using bonding systems. The aim of this study was to compare the microleakage of three self etch bonding agents (generation 6 and 7 in class 5 composite cavities. Materials and Methods: In this experimental study, 30 facial class 5 cavities were prepared in 30 human premolar teeth which were freshly extracted for orthodontic purposes. Cl V cavities were prepared in 2*3*2 mm dimensions. Occlusal margins were in enamel and gingival ones in cementum and randomly divided into 3 groups of 10 each. Then the cavities were treated by clearhil SE Bond (Kuraray, Japan, G Bond (GC, Japan, and Opti Bond Solo Plus (Kerr, USA, according to the manufacturers’ insductions. Then the cavities were filled using Z100 resin composite. The specimens were then immersed in a 50% AgNo solution for 24 hrs. Then, the teeth were cut buccolingually to be evaluated for dye penetration with stereomicroscope. Data were analyzed using Kruskal-Wallis test. Results: This study revealed that Opti bond solo plus had type1 microleakage (dye penetration up to 1/3 of cavity in 80% of specimen, and type 4 microleakage (along axial wall in 10%. Clearfil SE bond had no leakage in 50%, type1 in 40% and type 2 (up to 2/3 of cavity in 10%. But there was no significant difference in the microleakage at the gingival margins between 3 groups (P>0.05. Conclusion: Clearfil SE Bond and G bond could prevent microleakage more effectively than that of Opti Bond Solo Plus on the occlusal margins. However, no difference in the microleakage on the gingival surfaces was found.

    The main purpose of the present systematic review was to evaluate the quantitative effects of the pendulum appliance and modified pendulum appliances for maxillary molar distalization in Class II malocclusion. Our systematic search included MEDLINE, EMBASE, CINAHL, PsychINFO, Scopus and key journals and review articles; the date of the last search was 30 January 2017. We graded the methodological quality of the studies by means of the Quality Assessment Tool for Quantitative Studies, developed for the Effective Public Health Practice Project (EPHPP). In total, 203 studies were identified for screening, and 25 studies were eligible. The quality assessment rated four (16%) of the study as being of strong quality and 21 (84%) of these studies as being of moderate quality. The pendulum appliances showed mean molar distalization of 2-6.4 mm, distal tipping of molars from 6.67° to 14.50° and anchorage loss with mean premolar and incisor mesial movement of 1.63-3.6 mm and 0.9-6.5 mm, respectively. The bone anchored pendulum appliances (BAPAs) showed mean molar distalization of 4.8-6.4 mm, distal tipping of molars from 9° to 11.3° and mean premolar distalization of 2.7-5.4 mm. Pendulum and modified pendulum appliances are effective in molar distalization.

    Okolo, Cynthia M; Ferretti, Ralph P; MacArthur, Charles A

    2007-01-01

    In this study, we examined the nature of whole-class discussion and teachers' instruction during discussion about historical topics in one inclusive, middle-grade classroom. We videotaped and analyzed 4 lessons to determine the nature of discussion sequences, rates of participation, and instructional challenges encountered by the teacher and students. We triangulated our analysis of observational data with teacher interviews. The results showed high rates of student participation, with no differences between students with and without disabilities. The teacher initiated and controlled the discussion, and nearly all student responses were from teacher to student rather than from student to student. The teacher encountered three challenges in developing students' understanding, and we identify specific practices she used to address these challenges. Based on students' response to measures administered by project staff and on their scores on statewide tests, this teacher's practices seemed to be highly effective.

    1999-01-01

    Abstract This paper is motivated by the need to discuss the quality of life as a part of the background for devising environmental strategies. When environmental strategies are devised, it is often more or less tacitly assumed that we should try to avoid measures that imply a decrease in the level....... The critical perspective is developed by dealing with welfare or the quality of life: what does it mean to have a good life? On the basis of this discussion, the relationship between consumption and welfare can then be assessed. The approach to the discussion of the quality of life in this paper is first...... with the different themes in the discussion of the quality of life. The point of departure is taken in some critical considerations related to the traditional conceptualization of welfare. After that, some inspiration from the debate on basic needs is outlined and supplemented with some reflections on the dual...

    2008-06-01

    Full Text Available This paper presents an investigation of whether computer mediated communication (CMC can develop critical thinking in language classrooms. The research was conducted at a university branch campus in Malaysia over a period of 12 weeks. It involved three groups of learners in which each group was exposed to different discussion modes. The first group was exposed to a CMC discussion mode, the second group was exposed to a mixed mode of CMC and face-to-face (F2F discussions and the third group had only the face-to-face mode of discussion. The critical thinking development in these three conditions was evaluated based on the content analysis method used by Newman, Johnson, Cochrane and Webb (1995. This research reports the findings which hopefully will give some insight to other teaching practitioners who are interested in incorporating IT in their classrooms

    CERN Document Server

    1988-01-01

    In the past two years conferences on superconductivity have been characterized by the attendance of hundreds of scientists. Consequently, the organizers were forced to schedule numerous parallel sessions and poster presentations with an almost unsurveyable amount of information. It was, therefore, felt that a more informal get-together, providing ample time for a thourough discussion of some topics of current interest in high-temperature superconductivity, was timely and benefitial for leading scientists as well as for newcomers in the field. The present volume contains the majority of papers presented at the International Discussion Meeting on High-Tc Superconductors held at the Mauterndorf Castle in the Austrian Alps from February 7 to 11, 1988. Each subject was introduced in review form by a few invited speakers and then discussed together with the contributed poster presentations. These discussion sessions chaired by selected scientists turned out to be the highlights of the meeting, not only because all ...

    Katherine E Kruse

    Full Text Available In the context of serious or life-limiting illness, pediatric patients and their families are faced with difficult decisions surrounding appropriate resuscitation efforts in the event of a cardiopulmonary arrest. Code status orders are one way to inform end-of-life medical decision making. The objectives of this study are to evaluate the extent to which pediatric providers have knowledge of code status options and explore the association of provider role with (1 knowledge of code status options, (2 perception of timing of code status discussions, (3 perception of family receptivity to code status discussions, and (4 comfort carrying out code status discussions.Nurses, trainees (residents and fellows, and attending physicians from pediatric units where code status discussions typically occur completed a short survey questionnaire regarding their knowledge of code status options and perceptions surrounding code status discussions.Single center, quaternary care children's hospital.203 nurses, 31 trainees, and 29 attending physicians in 4 high-acuity pediatric units responded to the survey (N = 263, 90% response rate. Based on an objective knowledge measure, providers demonstrate poor understanding of available code status options, with only 22% of providers able to enumerate more than two of four available code status options. In contrast, provider groups self-report high levels of familiarity with available code status options, with attending physicians reporting significantly higher levels than nurses and trainees (p = 0.0125. Nurses and attending physicians show significantly different perception of code status discussion timing, with majority of nurses (63.4% perceiving discussions as occurring "too late" or "much too late" and majority of attending physicians (55.6% perceiving the timing as "about right" (p<0.0001. Attending physicians report significantly higher comfort having code status discussions with families than do nurses or trainees

    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.

    Full Text Available This paper examines how the discussion tool is used to promote critical thinking in an online environment at Marshall University. The significance of critical thinking in higher education has been brought to attention at both national and local levels. The paper studies the use of discussions as an approach to promote critical thinking in a number of English as a Second Language (ESL courses offered by Marshall University's Graduate School of Education and Professional Development (GSEPD program. At the end of the semester, a qualitative survey was developed to identify the effectiveness of such discussions, and the opportunities for improvement. The survey was sent to all students in these three classes. These students were all full time teachers in Elementary and Secondary schools in West Virginia. Out of 21 students, 15 of them have responded to the three questions asked in the survey. Almost all the respondents have found discussion helpful in enhancing learning and critical thinking. Most students support the involvement of an online instructor in the online discussion, and faculty members involved in these discussions function as helpers in the development of critical thinking skills.

    Teenagers' communication with their partners about sex and their use of condoms may be influenced by the discussions teenagers have with their parents about sex. However, little is known about the process of parent-teenager communication on this topic. Understanding both what parents discuss with their children and how they discuss it may lead to a greater understanding of teenagers' sexual behavior. Interviews were conducted with 372 sexually active black and Hispanic youth aged 14-17 from Alabama, New York and Puerto Rico. Regression analyses were used to examine parent-teenager discussions about sexuality and about sexual risk, and parental communication skills as predictors of teenagers' discussions about sexual risk with a partner and teenagers' condom use. Parent-teenager discussions about sexuality and sexual risk were associated with an increased likelihood of teenager-partner discussions about sexual risk and of teenagers' condom use, but only if parents were open, skilled and comfortable in having those discussions. Teenagers' communication with their partner about sexual risk also was associated with greater condom use, but the relationship between parent-teenager communication and teenagers' condom use was independent of this association. The influence on teenagers of parent-teenager discussions about sexuality and sexual risk depends on both what parents say and how they say it. Programs that foster parent-teenager communication about sexuality and sexual risk must emphasize both of these aspects.

    Full Text Available This article describes and analyzes efforts to use collaborative asynchronous discussion forums in a three semester online education program for NGO leaders and managers in Slovakia. Slovakia, as a country with autocratic styles of teacher-centered education, presents strong barriers to the implementation of collaborative learning activities. The authors used Garrison’s four stage cognitive processing categories to analyze some of the online discussions in the program. The two higher order critical thinking categories – integration and solution – appeared in student discussions only when prompted by specific instructional techniques.

    2016-04-01

    Discussion of religion and/or spirituality in the medical consultation is desired by patients and known to be beneficial. However, it is infrequent. We aimed to identify why this is so. We set out to answer the following research questions: Do doctors report that they ask their patients about religion and/or spirituality and how do they do it? According to doctors, how often do patients raise the issue of religion and/or spirituality in consultation and how do doctors respond when they do? What are the known facilitators and barriers to doctors asking their patients about religion and/or spirituality? A mixed qualitative/quantitative review was conducted to identify studies exploring the physician's perspective on discussion of religion and/or spirituality in the medical consultation. We searched nine databases from inception to January 2015 for original research papers reporting doctors' views on discussion of religion and/or spirituality in medical consultations. Papers were assessed for quality using QualSyst and results were reported using a measurement tool to assess systematic review guidelines. Overall, 61 eligible papers were identified, comprising over 20,044 physician reports. Religion and spirituality are discussed infrequently by physicians although frequency increases with terminal illness. Many physicians prefer chaplain referral to discussing religion and/or spirituality with patients themselves. Such discussions are facilitated by prior training and increased physician religiosity and spirituality. Insufficient time and training were the most frequently reported barriers. This review found that physician enquiry into the religion and/or spirituality of patients is inconsistent in frequency and nature and that in order to meet patient needs, barriers to discussion need to be overcome. © The Author(s) 2015.

    To enhance continuing professional development and address the risk that professional isolation poses, the UK General Optical Council introduced a requirement for all optometrists to engage in at least one case-based discussion per 3 year cycle of continuing education. In this paper, we explore participants' impression of the acceptability, effectiveness and long-term impact-on-practice of case-based discussion as a mode of continuing education. Case-based discussion participants attended an evening session comprising a lecture and a group discussion. They completed three questionnaires: prior to the session, immediately post-session and 3-4 months post-session. We coded the questionnaires to allow matching. Seventy-five case-based discussion groups were held with 379 participants; 377 completed both pre- and post-questionnaires and 331 (88%) returned a follow-up questionnaire. Case-based discussions were an acceptable method of learning, with many preferring it to distance-learning. Prior to the event, women, employees and part-time workers were more likely to have concerns about participating. In terms of learning, gaps in knowledge were more likely to be revealed in those who work in isolation. The respondents highlighted social aspects, reassurance of practice as well as new learning. Participants significantly improved self-confidence ratings in all key learning areas. At three months post-session, the majority (75%) self-reported that they had implemented their intended changes to practice. The evaluation showed that participants felt that case-based discussion developed their knowledge, notably for sole practitioners, and influenced later workplace practice. The peer interaction of this mode of continuing education can combat professional isolation. © 2014 The Authors Ophthalmic & Physiological Optics © 2014 The College of Optometrists.

  4. Scaffolding scientific discussion using socially relevant representations in networked multimedia

    1999-11-01

    How do students make use of social cues when learning on the computer? This work examines how students in a middle-school science course learned through on-line peer discussion. Cognitive accounts of collaboration stress interacting with ideas, while socially situated accounts stress the interpersonal context. The design of electronic environments allows investigation into the interrelation of cognitive and social dimensions. I use on-line peer discussion to investigate how socially relevant representations in interfaces can aid learning. First, I identify some of the variables that affect individual participation in on-line discussion, including interface features. Individual participation is predicted by student attitudes towards learning from peers. Second, I describe the range of group outcomes for these on-line discussions. There is a large effect of discussion group on learning outcomes which is not reducible to group composition or gross measures of group process. Third, I characterize how students (individually) construct understanding from these group discussions. Learning in the on-line discussions is shown to be a result of sustained interaction over time, not merely encountering or expressing ideas. Experimental manipulations in the types of social cues available to students suggest that many students do use socially relevant representations to support their understanding of multiple viewpoints and science reasoning. Personalizing scientific disputes can afford reflection on the nature of scientific discovery and advance. While there are many individual differences in how social representations are used by students in learning, overall learning benefits for certain social representations can be shown. This work has profound implications for design of collaborative instructional methods, equitable access to science learning, design of instructional technology, and understanding of learning and cognition in social settings.

    To assess how much information communicated to patients is understood and retained after preoperative discussion of upper extremity procedures. A prospective study was designed by recruiting patients prior to undergoing upper extremity surgical procedures after a detailed discussion of their operative technique, postoperative care and treatment outcomes. Patients were given the same 20-item questionnaire to fill out twice, at two pre operative visits. An independent evaluator filled out a third questionnaire as a control. Various discussion points of the survey were compared among the 3 questionnaires and retained information and perceived comprehension were evaluated. The average patients' age was 50.3 (27-75) years The average time between the two surveys preoperative 1 and preoperative 2 was 40.7 (7-75) days,. The average patient had approximately 2 years of college or an associate's degree. Patients initially retained 73% (52-90%) of discussion points presented during preoperative 1 and 61% (36-85%) of the information at preoperative 2 p = .002. 50% of patients felt they understood 100% of the discussion, this dropped to only 10% at their preoperative 2 visit. 15% of our patients did not know what type of anesthesia they were having at preoperative 2. A communication barrier between patients and physicians exists when patients are informed about their preoperative surgical discussion. The retention of information presented is worsened with elapsing time from the initial preoperative discussion to the second preoperative visit immediately prior to surgery. Methods to enhance patients' retention of information prior to surgery must be sought and implemented which will improve patients' treatment outcome.

    Examine association of comprehensiveness of colorectal cancer (CRC) screening discussion by primary care physicians (PCPs) with completion of CRC screening. Observational study in Kaiser Permanente Northwest, a group-model health maintenance organization. A total of 883 participants overdue for CRC screening received an automated telephone call (ATC) between April and June 2009 encouraging CRC screening. Between January and March 2010, participants completed a survey on PCPs' discussion of CRC screening and patient beliefs regarding screening. receipt of CRC screening (assessed by electronic medical record [EMR], 9 months after ATC). Primary independent variable: comprehensiveness of CRC screening discussion by PCPs (7-item scale). Secondary independent variables: perceived benefits of screening (4-item scale assessing respondents' agreement with benefits of timely screening) and primary care utilization (EMR; 9 months after ATC). The independent association of variables with CRC screening was assessed with logistic regression. Average scores for comprehensiveness of CRC discussion and perceived benefits were 0.4 (range 0-1) and 4.0 (range 1-5), respectively. A total of 28.2% (n = 249) completed screening, 84% of whom had survey assessments after their screening date. Of screeners, 95.2% completed the fecal immunochemical test. More comprehensive discussion of CRC screening was associated with increased screening (odds ratio [OR] = 1.51, 95% confidence interval [CI] = 1.03-2.21). Higher perceived benefits (OR = 1.46, 95% CI = 1.13-1.90) and 1 or more PCP visits (OR = 5.82, 95% CI = 3.87-8.74) were also associated with increased screening. More comprehensive discussion of CRC screening was independently associated with increased CRC screening. Primary care utilization was even more strongly associated with CRC screening, irrespective of discussion of CRC screening.

    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.

  8. Semiology of aphasias: a critical discussion / Semiologia das afasias: uma discussão crítica

    Full Text Available The article discusses the semiology of aphasias, which started being developed in the 19th century by Broca and Wernicke. We do not provide an exhaustive list of symptoms and syndromes to address the theme, since we aim to critically discuss why the semiology of aphasias is still based mainly on organic perspectives in clinical practice and scientific research. We also discuss the contributions of Luria and Jakobson to a better understanding of how language is affected in aphasias and how Modern Linguistics, in special the Discursive Neurolinguistics, may enlighten the debate. We analyze some data to illustrate the theoretical and methodological assumptions of the above mentioned approaches and also discuss the excessive strength that classifications have in the clinical context.

    This study was undertaken to determine when patients feel that physician inquiry about spirituality or religious beliefs is appropriate, reasons why they want their physicians to know about their spiritual beliefs, and what they want physicians to do with this information. Trained research assistants administered a questionnaire to a convenience sample of consenting patients and accompanying adults in the waiting rooms of 4 family practice residency training sites and 1 private group practice in northeastern Ohio. Demographic information, the SF-12 Health Survey, and participant ratings of appropriate situations, reasons, and expectations for physician discussions of spirituality or religious beliefs were obtained. Of 1,413 adults who were asked to respond, 921 completed questionnaires, and 492 refused (response rate = 65%). Eighty-three percent of respondents wanted physicians to ask about spiritual beliefs in at least some circumstances. The most acceptable scenarios for spiritual discussion were life-threatening illnesses (77%), serious medical conditions (74%) and loss of loved ones (70%). Among those who wanted to discuss spirituality, the most important reason for discussion was desire for physician-patient understanding (87%). Patients believed that information concerning their spiritual beliefs would affect physicians' ability to encourage realistic hope (67%), give medical advice (66%), and change medical treatment (62%). This study helps clarify the nature of patient preferences for spiritual discussion with physicians.

  10. ECONOMIC DESIGN IN SOCIALISM: MODERN UNDERSTANDING OF DISCUSSION

    Full Text Available Necessity of improvement of the system pertaining to distribution of limited resources obligatory leads to reduction of state interference in these processes. While discussing the economic design in socialism in the period of 1920–1930 the Austrian school presented significant arguments against any interference in resource distribution. Socialists’ objections (initial idea of socialism as money-free economy; possibility to determine price structure that excludes deficit and glut in the market fail to pass theoretical and time testing. The existing opinion that the Austrians are losers in this discussion is related to their permanent additional arguments without acknowledging their own mistakes that had been made in their previous discussions and declaring that their opponents occupy positions at the second line of the defense. Last works of Austrian representatives re-consider final results of the discussion about the possibility of economic design in socialism taking into account changes in general approach to evaluation of the results of scientific discussion

    Full Text Available In this article seeks to discuss the connections between men and health addressing some scratches of masculinity. At first, bring up some data from the thematic seminar "Being a man today: discussing some scratches masculinity," presented at the International Seminar Reviews Routes III, held in Porto Alegre, Brazil, in 2011. Therefore, we discuss the process of male socialization and scores some aspects of everyday life that can endanger / or scratch threaten masculinity, such as seeking care and even the aging process itself. It is noted that the heteronormative masculinity configures itself as the hegemonic model, stand out among other models. So, being a man is to fulfill roles and prescriptions which are rooted in a society that is structured on the basis of gender, even for this have to endanger your health.

  12. Synthetic biology analysed tools for discussion and evaluation

    CERN Document Server

    2016-01-01

    Synthetic biology is a dynamic, young, ambitious, attractive, and heterogeneous scientific discipline. It is constantly developing and changing, which makes societal evaluation of this emerging new science a challenging task, prone to misunderstandings. Synthetic biology is difficult to capture, and confusion arises not only regarding which part of synthetic biology the discussion is about, but also with respect to the underlying concepts in use. This book offers a useful toolbox to approach this complex and fragmented field. It provides a biological access to the discussion using a 'layer' model that describes the connectivity of synthetic or semisynthetic organisms and cells to the realm of natural organisms derived by evolution. Instead of directly reviewing the field as a whole, firstly our book addresses the characteristic features of synthetic biology that are relevant to the societal discussion. Some of these features apply only to parts of synthetic biology, whereas others are relevant to synthetic bi...

  13. Social and legal dimensions discussion of conscientious refusal in Turkey

    Full Text Available Even though the discussion of conscientious objection, the refusal of military service due to individual’s moral values or religious beliefs, is new in Turkey, the subject has become the focus of intense interest. The discussion of conscientious objection in Turkey has come the to the fore with the heated debates between the glorification of the dynamics of Turkish social structure towards military service and the critique of militarism and conscientious objection’s legal dimensions, as well. Since the reduction of discussions in this context in Turkey to the legal dimension is the ignorance of social reality constituting basis to the legal dimension, the subject is examined with reference to the social and historical outlook on this issue and the study is built on dimensions.

  14. Suppression and repression: A theoretical discussion illustrated by a movie

    Full Text Available The first translations of Freud's work into Portuguese have presented problems because they were not translated from the German language. More than a hundred years after the beginning of Psychoanalysis, there are still many discussions on Freud's metapsychology and a considerable difficulty in obtaining a consensus on the translation of some concepts. This paper refers back to Freud's concepts of primal repression, repression and suppression. In order to discuss such concepts, we have made use of a film, co-produced by Germans and Argentineans, which is named "The Song in me" (Das Lied in mir, released to the public in 2011 and directed by Florian Micoud Cossen. Through this motion picture, the following of Freud's concepts are analyzed, and the differentiation between them is discussed: suppression and repression, as well as the importance of their precise translation.

    1958-07-01

    Theoretical discussions of the diamagnetic effects and of the mirror enhancement brought about by the ion centrifugal force are presented and experiments are discussed. The successive operation of three models of Ixion are reported. The models differ primarily in the ranges of electric and magnetic fields which were used and in the series inductances of the electrical leads which in each case connected Ixion to energized capacitor banks. The first two models are with metallic center electrodes, while the latest version, Ixion III, has a 'plasma center electrode' It is believed that these experiments demonstrate the containment of a rotating plasma, although impurities are limiting the energy that can be contained.

    Full Text Available Existing literature on education and technology has frequently highlighted the usefulness of online discussion forums for distance courses; however, the majority of such investigations have focused their attention only on text-based forums. The objective of this paper is to determine if the embedding of streamed videos in online discussion forums generates educational dialogue and consequently the feedback that students need in a Management Accounting Course. The findings suggest some interesting issues, such as: students prefer text answers except in complex questions, and videos never replace text commentaries and explanations, but rather complement them.
