Im Gegensatz dazu stellt das ''Integritaetskonzept'' als Umsetzung des Basissicherheitskonzepts unter Beruecksichtigung der jeweiligen anlagenspezifischen Voraussetzungen ein geschlossenes Gesamtkonzept dar, das der Notwendigkeit einer mehrstufigen Absicherung und ''laufender'' Aktualisierung Rechnung traegt. Das Integritaetskonzept ist Bestandteil des Alterungsmanagements fuer mechanische Komponenten und Systeme. Am Beispiel der Speisewasserleitung innerhalb Containment der Anlage GKN 1 wird dessen praktische Anwendung zum Nachweis der Integritaet aufgezeigt. (orig.)

Das Rhizom von Potentilla officinalis (PO) ist reich an Gerbstoffen und wird traditionell zur äußerlichen Behandlung von Entzündungen der Haut und der Schleimhäute verwendet. Ziel der vorliegenden Arbeit war die Bestätigung der antiinflammatorischen Eigenschaften von PO mittels eines UV-Erythem-Tests und einer klinischen Anwendungsstudie bei atopischer Haut. Die antiinflammatorische Wirkung eines PO-Extrakts (standardisiert auf 2 % Trockensubstanz) wurde in einer prospektiven, randomisierten, placebokontrollierten Doppelblindstudie mit 40 gesunden Erwachsenen im UV-Erythem-Test im Vergleich zu 1 % Hydrocortisonacetat untersucht. Im Rahmen einer prospektiven nicht kontrollierten Studie wurde die Wirkung und Verträglichkeit der 2 % PO-Creme an zwölf Erwachsenen und zwölf Kindern mit atopischer Haut nach Anwendung über zwei Wochen in einem definierten Testareal anhand eines Teil-SCORAD untersucht. Zusätzlich wurde die Beeinflussung der Hautrötung im Testareal photometrisch gemessen. Im UV-Erythem-Test zeigte die PO-Creme eine signifikante Reduktion des Erythemindex im Vergleich zum Vehikel. Die antiinflammatorische Wirkung des Verums entsprach der der 1 % Hydrocortisonacetat-Creme. Die klinische Studie bei Atopikern zeigte eine signifikante Abnahme des Teil-SCORAD und des Erythems im Testareal. Es wurden keine Unverträglichkeitsreaktionen beobachtet. PO als 2%ige Zubereitung besitzt entzündungshemmende Eigenschaften und ist wirksam und gut verträglich auf atopischer Haut. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

the studies showed, for the period of evaluation, an overall trend towards reduction. (orig.) [German] Ziel: Im Rahmen dieser Studie wurde die Anwendung radioaktiver Stoffe am Menschen in der nuklearmedizinischen Forschung und die damit fuer die Probanden verbundene Strahlenexposition analysiert. Methodik: Hierzu wurden die zwischen 1997 und 1999 vom Bundesamt fuer Strahlenschutz zusammen mit dem Bundesinstitut fuer Arzneimittel und Medizinprodukte begutachteten Antraege nach paragraph 41 Strahlenschutzverordnung ausgewertet. Ergebnisse: Der Schwerpunkt der begutachteten Studien zur diagnostischen Anwendung radioaktiver Stoffe hat sich seit 1998 von onkologischen auf neurologisch/psychiatrische Fragestellungen verlagert, wobei die Anzahl der PET-Studien stetig zunahm. Der Anteil der in diagnostische Studien einbezogenen gesunden Probanden ist von 7 auf 22% angestiegen. Therapeutische Anwendungen radioaktiver Stoffe nahmen seit 1997 um das Dreifache zu, wobei der Schwerpunkt im Bereich der Radioimmuntherapie und der endovaskulaeren Brachytherapie lag. Fuer bis zu 49% der untersuchten gesunden Probanden war die effektive Dosis hoeher als 5 mSv, fuer bis zu 6% dieser Probanden lag sie ueber 20 mSv. Bis zu 22% der Patienten erhielten im Rahmen diagnostischer Studien eine effektive Dosis von 20-50 mSv. Eine Ueberschreitung der 50-mSv-Grenze trat bei bis zu 3% der Patienten auf. Schlussfolgerungen: Trotz zunehmender Anwendung der PET behaelt die konventionelle Nuklearmedizin ihre Bedeutung in der medizinischen Forschung. Weiterentwicklungen auf dem Gebiet der Radiochemie und Molekularbiologie fuehrten zu einer zunehmenden Bedeutung der Radioimmuntherapie. Die Evaluierung neuer Radiopharmaka und die Erweiterung der biomedizinischen Grundlagenforschung resultierte in einem Anstieg des Anteils der in die Studien einbezogenen gesunden Probanden. Die studienbedingte Strahlenexposition der Probanden zeigte fuer den ausgewerteten Zeitraum insgesamt einen ruecklaeufigen Trend

After the new radiation protection ordinance has come into effect with July 20th, 2001 the approval process for application of radiation substances or ionizing radiation in medical research changed considerably with respect to the responsibility of the Federal Office for Radiation Protection as the approval authority, the participation of an approved ethic committee, the inclusion of an expert for medical physics for planning and execution of the study as well as stricter regulations for cover clause. On the contrary, existing regulations have been facilitated since the effective dose limit for volunteers has been increased from 10 to 20 mSv and a central procedure for approval of multicenter studies has been introduced. Moreover, the application of radioactive substances or ionizing radiation for research in people without or with restricted legal capacity is no more totally prohibited. At present, changes of the radiation protection ordinance and the atomic law cover clause ordinance with respect to medical research are in discussion. (orig.) [German] Nach In-Kraft-Treten der neuen Strahlenschutzverordnung vom 20.07.2001 ergeben sich wesentliche Aenderungen des Genehmigungsverfahrens fuer die Anwendung radioaktiver Stoffe oder ionisierender Strahlung in der medizinischen Forschung bezueglich der Zustaendligkeit des Bundesamts fuer Strahlenschutz als Genehmigungsbehoerde, der Einschaltung einer akkreditierten Ethikkommission, der Hinzuziehung eines Medizinphysik-Experten bei der Studien-Planung und -Anwendung sowie verschaerfter Regelungen zur Deckungsvorsorge. Eine gewisse Erleichterung bisher bestehender Regelungen ist in der Erhoehung des Grenzwerts der effektiven Dosis fuer Probanden von 10 auf 20 mSv sowie dem zentralen Genehmigungsverfahren fuer Multizenter-Studien zu sehen. Ausserdem ist eine Anwendung radioaktiver Stoffe oder ionisierender Strahlung in der Forschung an geschaeftsunfaehigen und beschraenkt geschaeftsfaehigen Probanden nicht mehr voellig

Before a magnetic resonance imaging (MRI) examination, implants in patients must be cleared for MR safety in order to exclude the risk of possible severe injuries and implant malfunction in an MR environment. The general contraindication for measurements of patients with implants still applies; however, in the recent past a way has been found to legally circumvent this contraindication. For this purpose special conditions are required: explicit implant identification and the original manufacturer's labelling are necessary, the required conditions for conditionally MR safe implants must be assured and a risk-benefit analysis with appropriate explanation to the patient has to be performed. This process can be very complex as the implants are often poorly documented and detailed information on the implant MR labelling is also often outdated or not easy to interpret. This article provides information about legal and normative principles of MR measurement of patients with implants. The possible physical interactions with implants will be briefly dealt with as well as possible strategies for better identification and investigation of implants and MR labelling. General approaches for minimizing the risk will be discussed using some examples. The second part deals with the content of MR implant labelling and the current test standards. Furthermore, the additional information from the operating instructions of the MR scanner that are necessary for the interpretation of the MR implant labelling, will be explained. The article concludes with an explanation of the current pattern for MR labelling of implants from the U.S. Food and Drug Administration (FDA) and an exemplary application. (orig.)

The shale gas production using the so-called fracking method represents for opponents the use of a high-risk technology. Proponents see it, however a technological advance, and the answer to current energy issues. For the citizens of a country, the debate involves mainly uncertainties, the technology is still associated with risks that are not only difficult to assess for the layman. Due to these uncertainties, there is a danger that scientific evidence for political purposes are exploited. Particularly exciting is therefore the question of how the subject is discussed in different countries. In Fracking in the conflict area between energy and environmental policies are the debates in natural gas country Netherlands and the country of energy transition, Germany are compared. Kerstin Kontry's research put emphasis on the parties to the debate actors, the course of the debate and the issues are discussed. The main question is to what extent the discussions are shaped by national factors. [German] Die Schiefergasfoerderung mit Hilfe der sogenannten Fracking-Methode stellt fuer Gegner die Anwendung einer Hochrisikotechnologie dar, Befuerworter sehen darin hingegen einen technologischen Fortschritt und die Antwort auf derzeitige Energiefragen. Fuer die Buerger eines Landes birgt die Debatte vor allem Unsicherheiten, ist die Technologie doch mit Risiken verbunden, die nicht nur fuer den Laien schwer einzuschaetzen sind. Aufgrund dieser Unsicherheiten droht die Gefahr, dass wissenschaftliche Erkenntnisse fuer politische Zwecke instrumentalisiert werden. Besonders spannend ist daher die Frage, wie die Thematik in unterschiedlichen Laendern diskutiert wird. In Fracking im Spannungsfeld zwischen Energie- und Umweltpolitik werden die Debatten im Erdgasland Niederlande und dem Land der Energiewende, Deutschland, verglichen. Den Schwerpunkt legt Kerstin Kontny dabei auf die an der Debatte beteiligten Akteure, den Verlauf der Debatte sowie die behandelten Themen. Dabei

PEM fuel cells are gaining increasing importance for use in automotive application. The goal of the research program reported here was to develop the basic technology and components for PEMFC stacks for use in transport applications. The sub-task of Degussa was to develop improved electrocatalysts for PEMFC single cells and stacks. The technical objectives of the research project were met. Electrocatalysts, characterized by a high Pt-dispersion, high surface area and excellent activity, were developed. With this material, considerable progress was made to reduce the total platinum loading of PEMFC cells and stacks to about 0,5 mgPt/cm{sup 2}. With this value, the goal of the program (<0,8 mg/cm{sup 2}) was significantly surpassed. Additionally, higher power densities of >0.4 W/cm{sup 2} were achieved at Degussa for hydrogen/air and reformate/air operation of the PEMFC. A CO-tolerant anode electrocatalyst, exhibiting a CO-tolerance of up to 100 ppm CO, enables the operation of PEMFC stacks with on-board generated methanol reformate. The performance of the new electrocatalyst materials was verified by DaimlerChrysler in a PEMFC demonstration stack at the end of the program. (orig.) [Deutsch] PEM-Brennstoffzellen gewinnen fuer die mobile Anwendung immer mehr an Bedeutung. Im Rahmen des hier beschriebenen Leitprojektes sollten die Basistechnologien fuer den Einsatz der PEM-Brennstoffzelle im mobilen Bereich (Elektrotraktion) entwickelt werden. Das Teilprojekt der Degussa befasst sich mit der Entwicklung von verbesserten Elektrokatalysatoren fuer PEM-Brennstoffzellenstacks. Die technischen Arbeitsziele des Vorhabens wurden erreicht. So konnten Elektrokatalysatoren bereitgestellt werden, die sich durch eine hohe Pt-Dispersion, eine grosse Pt-Oberflaeche sowie eine sehr gute Aktivitaet auszeichnen. Mit diesen Elektrokatalysatoren gelang es, die Platinbeladung der PEM-Elektroden (Anode und Kathode) erheblich abzusenken. Mit einer Gesamtplatinbeladung von 0,5 mg/cm{sup 2

The project investigated non-toxic additives for production of ice slurry. Ice slurry is an environment-friendly refrigerant that is increasingly used as a substitute for conventional refrigerants. In view of rising energy prices and an impending tax on climate-relevant refrigerants, ice slurry may soon be used for chilling of food in supermarkets. For this, ice slurry of about 0 C is required for normal cooling and of about -25 C for deep freezing. A very fine-grained, pumpable ice slurry is obtained with glucose as an additive, or with sodium chloride in eutectic concentration with small amounts of ethanol for deep freezing. Ethanol will refine the coarse crystal structure of the eutectic sodium chloride / water mixture and will also reduce the freezing point. Further, the method of primary crystallisation on a crystallised additive was developed. An industrial plant working by this principle will have less disturbances and wear during ice slurry production. [German] Die Projektarbeit befasste sich mit der Untersuchung lebensmittelvertraeglicher Additive zur Herstellung von Eisbrei. Eisbrei gilt als umweltfreundlicher Kaeltetraeger, der zunehmend in verschiedenen Bereichen zur Anwendung kommt und herkoemmliche Kaeltemittel ersetzen kann. Aufgrund steigender Energiekosten sowie einer eventuell anstehenden Besteuerung treibhauswirksamer Kaeltemittel, kann Eisbrei zukuenftig zur Kuehlung von Lebensmitteln in Supermaerkten verwendet werden. Dazu wird Eisbrei mit ca. 0 C fuer die Normalkuehlung, beziehungsweise mit ca. -25 C fuer die Tiefkuehlung benoetigt. Mit Glucose als Zusatzstoff laesst sich ein sehr feinkoerniger und damit pumpbarer Eisbrei fuer die Normalkuehlung erzeugen. Bei der Tiefkuehlung ist Natriumchlorid in einer eutektischen Konzentration mit geringen Mengen Ethanol empfehlenswert. Ethanol verfeinert die grobe Kristallstruktur des reinen eutektischen Natriumchlorid-Wasser-Gemisches und senkt den Gefrierpunkt. Des Weiteren wurde das Verfahren der

The ''Scratch Test'' is, arguably, the earliest and amongst the now most widely used techniques for evaluating a wide range of surface mechanical properties. Some of the areas where this test has been successfully used in the engineering field, both by research and industry, include the determination of the relative hardness of materials, characterizations of coatings, paints and thin-films, modeling of the wear of materials and the estimation of different material deformation characteristics when subjected to hard asperity damage. In this paper we have reviewed the ''state-of-the-art'' in the scratch method for polymeric materials. The paper provides some important theoretical models that have been developed in the field of scratching for material property characterizations. Results from different types of scratch tests (macro, micro and nano scales) on a range of polymeric materials are presented with critical discussion on the usefulness of each result. Finally, various areas for further research in scratching of polymer surfaces have been identified. (Abstract Copyright [2003], Wiley Periodicals, Inc.) [German] Der ''Ritztest'' ist wohl das aelteste und mit am meisten verwendete Verfahren zur Beurteilung von oberflaechenmechanischen Eigenschaften.

Encouraging Classroom Discussion

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.

Discussion in Postsecondary Classrooms

Curt Dudley-Marling

2013-11-01

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.”

Information and communication technology facilitates data acquisition, recording, evaluation and transmission in many fields of society, but even experts tend to get lost in the flood of data that are available. In order to make it possible to integrate new technological developments in information systems, the Minister of Environment and Transportation continues the project AJA (''Application of JAVA-based solutions'') which was started in 2000. AJA is a sequel to the GLOBUS project which was terminated in 1999. (GLOBUS - Globale Umweltsachdaten im UIS Baden-Wuerttemberg und anderen Systemen). [German] Die Bereiche Umwelt, Verkehr und Verwaltung profitieren bei der Erhebung, Erfassung, Auswertung, Darstellung und Weitergabe ihrer Daten in hohem Masse von Informations- und Kommunikationstechnik (IuK). Manche Darstellungsweisen und Berechnungen werden dadurch erst moeglich. Uebergreifende Zusammenhaenge koennen mit Hilfe der IuK aufgezeigt werden. Die Verwaltung muss Technologien einsetzen, wie sie in der Wirtschaft fuer die Zusammenfuehrung von verteilten Unternehmensdaten verwendet werden, um Entscheidungs grundlagen fuer die Unternehmenspolitik zu liefern (z.B. Data Warehouse). In solchen ''Warenhaeusern von Daten'' finden sich oft nur Experten zurecht. Unsere Herausforderung ist es, diese komplexen Zusammenhaenge nicht nur dem Experten, sondern auch dem Buerger auf moeglichst einfache und wirtschaftliche Weise zu vermitteln.

Emotional discussions reduce memory recall.

Science.gov (United States)

Soleti, Emanuela; Wright, Daniel B; Curci, Antonietta

2017-05-01

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.

In order to keep German brown coal competitive, new technologies for enhanced efficiency of power generation from brown coal were developed in the past few years. At a water content of 50-60 percent by weight, much energy is lost for evaporation. Reduction of the water content will incur a 5 percent effiency enhancement. A new process was developed at Dortmund university, i.e. mechanical/thermal dehydration in which the water contained in brown coal is removed by heat and mechanical pressure. The process is described, and its applicability for other moist fuels, e.g. peat or waste from the paper and wood processing industry ist discussed. (orig./SR) [Deutsch] Damit Braunkohle in Deutschland als heimischer und subventionsfreier Energietraeger diesen Stellenwert behaupten und in Zukunft weiter ausbauen kann, wurde in den letzten Jahren verstaerkt die Entwicklung neuer Technologien zur Effizienzsteigerung der Braunkohleverstromung vorangetrieben. Bei der Verbrennung von Braunkohlen mit Wassergehalten von 50-60 Gew.-% ist in herkoemmlichen Kraftwerken ein erheblicher Teil des Energieinhaltes zur Verdampfung des Wassers mit Hilfe von heissen Rauchgasen in sogenannten Mahltrockungsanlagen erforderlich. Durch eine energetisch guenstige Reduzierung des Wassergehaltes vor der Verbrennung sind hier Wirkungsgradsteigerungen um bis zu 5 Prozentpunkte moeglich. Ein neues, fuer diese Aufgabenstellung einsetzbares Verfahren ist das am Lehrstuhl Energieprozesstechnik und Stroemungsmechanik der Universitaet Dortmund entwickelte Mechanisch/Thermische Entwaesserungsverfahren (MTE-Verfahren). Durch die kombinierte Anwendung von Waerme und mechanischem Druck laesst sich das in der Kohle enthaltene Wasser in fluessiger Form entfernen. Neben der Darstellung des MTE-Verfahrens am Beispiel von Braunkohle soll im folgenden auch auf die Moeglichkeiten der Anwendung des Verfahrens fuer andere feuchte Brennstoffe wie Torf und Abfaelle aus der Papier- und Holzverarbeitung eingegangen werden

Chinese women's participation in fertility discussions.

Science.gov (United States)

Li, L

1993-01-01

In an attempt to better understand the process through which the family planning (FP) programs and socioeconomic developments in China affect fertility, women's participation in fertility discussions with their husbands are examined as an intermediate factor in a study based on results of a random survey of 6654 ever-married women of reproductive age from 7 cities and 30 counties of Guangdong. First, it must be noted that Chinese couples do have individual choices (albeit quite limited ones) about their fertility; they can choose to follow or ignore government policy or they can choose to remain childless. The present study has 3 major hypotheses: 1) the more a woman is involved in fertility discussions with her husband, the fewer children she will have; 2) urban women with a higher educational status will be more likely to have such discussions; and 3) women who are contacted individually by FP personnel are more likely to be involved in fertility discussions. After a discussion of data collection and variables (number of living children, education of wife and husband, age at marriage, residence, living with parents, contacted by FP personnel, and discussion with husband), the results are presented in terms of zero-order correlation coefficients indicating their relationships. The bivariate analysis supported the hypotheses. Multiple regression analysis showed that age at marriage, education of wives and husbands, FP contacts, and participation in discussions remain significant fertility determinants (but the correlation between fertility and residence becomes trivial). A further regression model indicated that a woman's educational attainment is the most significant positive indication of their participation in fertility discussions. These results imply that as women's status continues to improve in China and the deeply-rooted patriarchal tradition loses hold, increased gender equity and education will influence a fertility decline. FP personnel could also

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.

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.

Establishing an early and reliable diagnosis of rheumatoid arthritis (RA) is of major importance but can be a great clinical challenge leading to direct therapeutic consequences. No single epidemiological, genetic, clinical, serological or radiological test exists which can exclusively diagnose RA. In general diagnosis of RA includes a case history, clinical signs, laboratory abnormalities and radiological examinations, viz. conventional radiography of the joints of the hands and feet. This review summarizes the most important radiological features of RA and the radiological findings of its closest differential diagnoses. (orig.) [German] Eine fruehe Diagnosestellung bei rheumatoider Arthritis (RA) stellt eine grosse klinische Herausforderung dar, da sich daraus unmittelbare therapeutische Konsequenzen ableiten. Es gibt keinen epidemiologischen, genetischen, klinischen, serologischen oder radiologischen Test, mit dessen alleiniger Anwendung die Diagnose der RA definitiv gestellt werden kann. Die Diagnose der RA erfolgt durch die Kombination von Patientenanamnese, klinischen Zeichen und serologischen Biomarkern in Zusammenschau mit der radiologischen Diagnostik, allen voran der Anwendung konventioneller Roentgenbilder der Haende und Fuesse. In diesem Uebersichtsartikel werden die wichtigsten radiologischen Merkmale zur Diagnose der RA und der diagnostisch haeufigsten Differenzialerkrankungen dargestellt. (orig.)

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.

[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.

Online discussion: Enhancing students' critical thinking skills

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.

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

Viewer Discussion is Advised. Video Clubs Focus Teacher Discussion on Student Learning

2014-06-01

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. Tuttavia poche sono le conoscenze relative alla progettazione di ambienti di apprendimento basati su video che siano efficaci per la formazione degli insegnanti. Un modello promettente è il “video club” (Sherin, 2000. Video club uniscono insegnanti che guardano ed analizzano insieme segmenti video delle proprie rispettive classi. L'idea è che gli insegnanti, guardando e discutendo segmenti video centrati sul pensiero degli alunni, imparino ad adottare durante l’insegnamento pratiche d'identificazione e analisi di pensieri degli alunni degni di nota e possano poi utilizzare ciò che hanno imparato nelle decisioni didattiche. Questo articolo affronta le questioni da considerare quando si configura un video club per la formazione degli insegnanti, come ad esempio la definizione di obiettivi per l'utilizzo dei video, le norme per la visione e discussione dei rispettivi video, la selezione

Empowerment: a conceptual discussion.

Science.gov (United States)

Tengland, Per-Anders

2008-06-01

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.

Practical radiation protection of the patient in radiological diagnostics; Praktischer Strahlenschutz am Patienten in der radiologischen Diagnostik

The use of radiation protection equipment can reduce the radiation exposure of patients. The aim was to show which patient shields should be used for the different types of examination. The results of multiple studies were compiled and analyzed and recommendations made for the use of patient shields. The absolute dose values and the protective effect were considered. Radiological protection should be used in many investigations; particularly in the case of CT investigations, a reasonable dose reduction potential exists due to the higher radiation dose. Based on these recommendations, workflow changes in some types of investigation are expected due to the use of additional patient shields. (orig.) [German] Durch die Verwendung von Strahlenschutzmitteln kann die Strahlenexposition von Patienten reduziert werden. Es soll dargestellt werden, welche Strahlenschutzmittel bei welchen Untersuchungen eingesetzt werden sollen. Die Ergebnisse von Studien wurden zusammengestellt, analysiert und daraus Empfehlungen fuer die Anwendung von Strahlenschutzmitteln erstellt. Dabei wurden die absoluten Dosiswerte und die Schutzwirkung beruecksichtigt. Bei vielen Untersuchungen sind Strahlenschutzmittel anzuwenden, insbesondere bei CT-Untersuchungen besteht aufgrund der hoeheren Strahlendosis ein gutes Dosisreduktionspotenzial. Aufgrund der Empfehlungen ist bei einigen Untersuchungsarten mit veraenderten Arbeitsablaeufen aufgrund der Anwendung weiterer Strahlenschutzmittel zu rechnen. (orig.)

A study of the application of the discrete-ordinate method (DOM) with remedy for the ray effects to the solution of surface radiation exchange is presented in this paper. The remedy for the ray effects is achieved by dividing the radiative intensity into the attenuated incident and the medium emitting components. To demonstrate the application of the technique, this work considers radiative heat transfer in a two-dimensional cylindrical enclosure filled with a nearly transparent medium. The results obtained by the present DOM are in excellent agreement with those by the radiosity/irradiation method. (orig.). With 4 figs., 3 tabs. [Deutsch] In der Arbeit wird ein Weg aufgezeigt, wie die Stoerstrahlungseffekte bei Anwendung der Methode der diskreten Ordinaten auf die Berechnung des Energietausches zwischen Oberflaechenstrahlern vermieden werden koennen. Dies laesst sich durch Aufspaltung der Strahlungsintensitaet in die abgeschwaechte einfallende und die vom Medium emittierte Komponente erreichen. Als Beispiel fuer die Anwendung dieses Verfahrens dient der Waermeaustausch durch Strahlung in einem zweidimensionalen zylindrischen Behaeltnis, das mit einem nahezu transparenten Medium befuellt ist. Die mit der modifizierten Methode erhaltenen Ergebnisse stimmen ausgezeichnet mit jenen nach dem klassischen Brutto-Verfahren ueberein. (orig.)

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.

Panel discussion: Nuclear cardiology

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

Summary of presentations and discussions

Takeuchi, Mitsuo

2008-01-01

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

2013-03-01

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.

Obtained adsorption isotherm are presented and discussed. Using the Tessiere's sequential extraction analysis a gross variability in binding of radionuclides on soils was found. The obtained results were processed with the correlation analysis and the compartment model

International Discussion Meeting on High-Tc Superconductors

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 ...

While quasistatic and kinematic methods for analysis and interpretation of deformation processes reached technical maturity long ago, dynamic models are still in the early development phase. Starting from an outline of the current state of knowledge and a proposal on the definition `Dynamic models`, two fundamentally different dynamic model approaches are described and discussed, i.e. input-output models and state models. Input-output models are discussed in some detail, and the results of such a model when applied to investigations of the deformation characteristics of an industria-scale turbine are presented. (orig.) [Deutsch] Waehrend im Bereich der s.g. quasi-statischen und kinematischen Verfahrensentwicklung zur Analyse und Interpretation von Deformationsprozessen nur noch wenige Verfeinerungen zu erwarten sind, steht man bei der Bereitstellung praxisreifer dynamischer Modelle noch weitestgehend am Anfang einer vielversprechenden Entwicklungsphase. Ausgehend von einem kurzen Ueberblick zum aktuellen Entwicklungsstand und einem Vorschlag zur Definition `Dynamischer Modelle` werden zwei grundsaetzlich verschiedene dynamische Modellansaetze - die Ein-Ausgangs-Modelle und Zustandsmodelle - beschrieben und bezueglich ihrer Vor- und Nachteile diskutiert. Nach einer tiefgruendigeren Behandlung von Ein-Ausgangs-Modellen folgen Ergebnisse der Anwendung eines solchen Modellansatzes zur Untersuchung des Deformationsverhaltens einer Grossturbine. (orig.)

Full Text Available O artigo discute a semiologia das afasias, que teve início no século XIX com Broca e Wernicke. Não é nosso objetivo fornecer uma lista exaustiva de sintomas e síndromes para tratar do tema, já que buscamos discutir criticamente por que a semiologia das afasias ainda se baseia principalmente em perspectivas orgânicas na prática clínica e na pesquisa científica. Também discutimos as contribuições de Luria e de Jakobson para uma melhor compreensão de como a linguagem está comprometida nas afasias e como a Lingüística Moderna, sobretudo a Neurolingüística Discursiva, pode iluminar o debate. Analisamos alguns dados para ilustrar os pressupostos teóricos e metodológicos das referidas abordagens e discutimos ainda o peso excessivo que as classificações têm no contexto clínico.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.

Challenges to code status discussions for pediatric patients.

Directory of Open Access Journals (Sweden)

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

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.

ECONOMIC DESIGN IN SOCIALISM: MODERN UNDERSTANDING OF DISCUSSION

Directory of Open Access Journals (Sweden)

A. V. Kovalev

2008-01-01

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. 

Dynamical networks of influence in small group discussions.

Science.gov (United States)

Moussaïd, Mehdi; Noriega Campero, Alejandro; Almaatouq, Abdullah

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.

Round table discussion during session 2

Mays, C.

2004-01-01

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.

Preoperative Surgical Discussion and Information Retention by Patients.

Science.gov (United States)

Feiner, David E; Rayan, Ghazi M

2016-10-01

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.

Round table discussion during session 1

International Nuclear Information System (INIS)

Aebersold, M.

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.

Smoothed Bootstrap und seine Anwendung in parametrischen Testverfahren

Directory of Open Access Journals (Sweden)

Handschuh, Dmitri

2015-03-01

Full Text Available In empirical research, the distribution of observations is usually unknown. This creates a problem if parametric methods are to be employed. The functionality of parametric methods relies on strong parametric assumptions. If these are violated the result of using classical parametric methods is questionable. Therefore, modifications of the parametric methods are required, if the appropriateness of their assumptions is in doubt. In this article, a modification of the smoothed bootstrap is presented (using the linear interpolation to approximate the distribution law suggested by the data. The application of this modification to statistical parametric methods allows taking into account deviations of the observed data distributions from the classical distribution assumptions without changing to other hypotheses, which often is implicit in using nonparametric methods. The approach is based on Monte Carlo method and is presented using one-way ANOVA as an example. The original and the modified statistical methods lead to identical outcomes when the assumptions of the original method are satisfied. For strong violations of the distributional assumptions, the modified version of the method is generally preferable. All procedures have been implemented in SAS. Test characteristics (type 1 error, the operating characteristic curve of the modified ANOVA are calculated.

Nuclear waste under glass, further discussion

Science.gov (United States)

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.

Evaluating Critical Thinking in Computer Mediated Communication Discussions

Directory of Open Access Journals (Sweden)

Faizah Mohamad

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

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

Smart functions might include, but are not limited to: automated data logging (reading, location, time); transfer (downloading) logged data to outside computer; computer assisted, remote calibration; linearity and dead time correction; performance trending; self diagnosis of faults; detector probe recognition; automated beta factor application; and automatic range selection. These smart functions are discussed

Radon in dwellings and lung cancer - a discussion

International Nuclear Information System (INIS)

Stranden, E.

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.

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 debate about death: an imperishable discussion?

Directory of Open Access Journals (Sweden)

FÉLIX BACIGALUPO

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

Shaping stereotypical behaviour through the discussion of social stereotypes.

Science.gov (United States)

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.

Best Friends’ Discussions of Social Dilemmas

Science.gov (United States)

McDonald, Kristina L.; Malti, Tina; Killen, Melanie; Rubin, Kenneth H.

2013-01-01

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

Considerable misgivings concerning the quality assurance systems exist among the energy supply enterprises. However, the proper utilisation of these systems creates cost transparency, increases economic efficiency and promotes customer satisfaction. A working group comprising representatives of the insular works and the propane-air producers for peak demand have critically examined the quality requirements in the field of product, operation, application and management of the gas supply on the basis of a well-defined performance commission. The evaluation of the enquiry at the member plants showed that, especially concerning the gas quality, network management, operational security and the organisational procedures, a demand for an efficient quality management exists. For a long-term execution of the service commission a certification according to ISO 9000-Series is recommended. (orig.) [Deutsch] In den Energieversorgungsunternehmen bestehen erhebliche Bedenken ueber die Nuetzlichkeit von Qualitaetssicherungssystemen. Deren richtige Anwendung schafft jedoch Kostentransparenz, steigert die Wirtschaftlichkeit und foerdert die Kundenzufriedenheit. Eine Arbeitsgruppe aus Vertretern der Inselwerke und der Propan-Luft-Spitzendeckung hat sich bei definiertem Leistungsauftrag mit den Qualitaetsanforderungen in den Bereichen Produkt, Betrieb, Anwendung und Management der Gasversorgung auseinandergesetzt. Die Auswertung der Umfrage bei den Mitgliedwerken zeigte, dass besonders bei der Gasqualitaet, der Netzbewirtschaftung, der Betriebssicherheit und der betrieblichen Ablauforganisation ein Bedarf an effizienter Qualitaetsbewirtschaftung besteht. Zur langfristigen Erfuellung des Dienstleistungsauftrages empfiehlt sich die Zertifizierung nach der ISO-9000er-Reihe. (orig.)

The purpose of the present study was to examine the suitability of plant/soil systems for cleaning organically polluted effluents and to assess the influence of plant growth and dissolved humic substances on processes leading to the elimination of organic pollutants. This involved an examination of sorption interactions between selected pollutants on the one hand and sand and root material on the other, use of vertically irrigated plant-bearing sand columns for simulating real plant-based wastewater treatment plants, assessment of the cleaning efficiency of these systems with respect to the employed model pollutants and determination of the contamination of the filter material and plants with pollutants. Radiotracer techniques were used to determine pollution paths of phenanthrene and its microbial degradation in the model system. [German] In der vorliegenden Arbeit wurde die Eignung von Pflanze/Boden-Systemen zur Reinigung carbochemisch belasteter Abwaesser untersucht und der Einfluss eines Pflanzenbewuchses sowie geloester Huminstoffe auf die Prozesse, die zur Entfernung organischer Schadstoffe fuehren, bewertet. Die Bearbeitung dieses Themas umfasste Untersuchungen zu Sorptionswechselwirkungen ausgewaehlter Schadstoffe mit Sand- und Wurzelmaterial, die Anwendung vertikal durchstroemter, bepflanzter Sandsaeulen zur Nachbildung realer Pflanzenklaeranlagen, die Erfassung der Reinigungseffizienz dieser Systeme fuer die Modellschadstoffe sowie die Bestimmung der Schadstoffkontamination des Filtermaterials und der Pflanzen. Unter Anwendung der Radiotracertechnik erfolgte darueber hinaus die Bestimmung der Schadstoffpfade von Phenanthren einschliesslich des mikrobiellen Abbaus im Modellsystem. (orig.)

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.

Summary of the presentations and discussions

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

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.

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.

Undergraduate nursing students have been documented to experience ethical distress during their clinical training and felt poorly supported in discussing the ethical issues they encountered. Research aims: This study was aimed at exploring nursing students' perceived opportunity to discuss ethical issues that emerged during their clinical learning experience and associated factors. An Italian national cross-sectional study design was performed in 2015-2016. Participants were invited to answer a questionnaire composed of four sections regarding: (1) socio-demographic data, (2) previous clinical learning experiences, (3) current clinical learning experience quality and outcomes, and (4) the opportunity to discuss ethical issues with nurses in the last clinical learning experience (from 0 - 'never' to 3 - 'very much'). Participants and research context: Participants were 9607 undergraduate nursing students who were attending 95 different three-year Italian baccalaureate nursing programmes, located at 27 universities in 15 Italian regions. Ethical considerations: This study was conducted in accordance with the Human Subject Research Ethics Committee guidelines after the research protocol was approved by an ethics committee. Overall, 4707 (49%) perceived to have discussed ethical issues 'much' or 'very much'; among the remaining, 3683 (38.3%) and 1217 (12.7%) students reported the perception of having discussed, respectively, 'enough' or 'never' ethical issues emerged in the clinical practice. At the multivariate logistic regression analysis explaining 38.1% of the overall variance, the factors promoting ethical discussion were mainly set at the clinical learning environment levels (i.e. increased learning opportunities, self-directed learning, safety and nursing care quality, quality of the tutorial strategies, competences learned and supervision by a clinical nurse). In contrast, being male was associated with a perception of less opportunity to discuss ethical issues

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 advancing biological knowledge of disease processes plays a central part in the progress of modern psychiatry. An essential contribution comes from the functional and structural brain imaging techniques (CT, MRI, SPECT, PET). Their application is important for biological oriented research in psychiatry and there is also a growing relevance in clinical aspects. This development is taken into account by recent diagnostic classification systems in psychiatry. The capabilities and limitations of functional brain imaging in the context of research and clinic will be presented and discussed by examples and own investigations. (orig.)

Does Feedback Influence Student Postings to Online Discussions?

Directory of Open Access Journals (Sweden)

Katrina A. Meyer, Ph.D.

2007-07-01

Full Text Available Feedback theory proposes that feedback influences the behavior of a system and its parts and that is governed by rules. This exploratory study attempts to test this theory in a graduate-level class on leadership theory. Twelve students were asked to participate in five online discussions, each lasting one week. The questions for each discussion were selected to be provocative and rich, without having any correct answer. At the end of the discussion, students were asked to indicate which posting and poster they felt was “best” or most valuable and why they felt the posting was “best.” There is mixed evidence that the voting influenced subsequent postings; some individuals did improve while others were consistently good or poor posters. Students selected postings that were (in declining frequency of occurrence: thoughtful or thought-provoking, well written or justified, uplifting, presented new information, same as their own opinions, changed me, or complex. These reasons are similar to those of the instructor, although the students’ difficulty in choosing and rationalizing a choice and the frequency at which students chose posts that captured their own thoughts and opinions are of some concern. This study provides some evidence that these graduate students could evaluate their own discussions without the instructor intruding or dictating an evaluation scheme, although this may not be true for other groups of online students.

These include requirements for a permanent increase of the level of performance of technical components and structures by the introduction of new materials, joining technologies and design principles, the problem of ageing components and life extension, an increased emphasis on non-destructive in-service inspection combined with improved NDT techniques, and also a number of failure events caused by fatigue and fracture The aim of the present paper is to give a brief state-of-the-art review on how fracture mechanics is applied in different industrial branches today. This is based on standards and guidelines in the aerospace industry, in the nuclear and fossil power generation, in the chemical and petrochemical and the pipeline industry, in civil engineering, offshore technique and other fields. Based on the review an outlook is given on a future development that would be reasonable and desirable from the point of view of a basically unified philosophy of fracture mechanics application.

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...

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.

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.

Online discussions with pregnant and parenting adolescents: perspectives and possibilities.

Science.gov (United States)

Valaitis, Ruta K; Sword, Wendy A

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.

Use of fracture mechanics in the US industry

Energy Technology Data Exchange (ETDEWEB)

Landes, J.D. [GKSS-Forschungszentrum Geesthacht GmbH (Germany). Inst. fuer Materialforschung

2001-07-01

The modern fracture mechanics technology began in the US in the 1960's. It was developed in response to failure problems that could not be explained by current technology. Some segments of the US industry were quick to embrace this new technology. The period of 1960 to middle 1980's marked a time of active fracture mechanics research in the US industry. From this various codes and assessment procedures have been developed to apply the fracture mechanics approach to evaluate the safety and reliability of critical structural components. This report discusses the US industry use of fracture mechanics. It considers the historical developments, some of the fracture mechanics tools that are available and present practices. Several different industry segments that have used the fracture mechanics approach are considered. These include aerospace, military, power generation, petrochemical and pipelines, metal producers, and construction/transportation. Their current use of the fracture mechanics methods involves the implementation of codes and procedures, the development of software packages, the use of outside consulting groups and some in-house research efforts.

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.

Images of three animal cadaver hips, 8 dissected patient femoral heads and 18 hip joints of human corpses, all either with arthrosis stage I-III or artificial cartilage defects, were compared with their corresponding anatomic sections. Additional histomorphologic examinations of the arthrotic cartilages were conducted, and MR-Imaging of 20 healthy and 21 arthrotic patient hips was performed using a specific traction method. Using a T{sub 1}-weighted 3-dimensional gradient-echo sequence and a traction of the hip joint, it was possible due to the low-signal imaging of the joint space to separate in vivo the high-signal femoral head cartilage from the high-signal acetabular cartilage. In horizontal position of the phase-encoding parameter, minimisation of the chemical-shift artifact, mainly in the ventro-lateral areas, was accomplished. MRI measurements of the articular cartilage widths showed significant correlations (p < 0.001) with the corresponding anatomic sections. At the same time the T{sub 1} 3-dimensional gradient-echo sequence of the lateral femoral head with r = 0.94 showed the lowest deviations of the measurements. It was possible with MR-Imaging to distinguish four cartilage qualities.

Teacher’s communication skill plays an important role, one of which is to guide a class discussion for teaching purposes. This study aimed to investigate a teacher’s mathematical communication profile in facilitating and guiding a class discussion. This study is qualitative. A junior teacher of high school (i.e., a teacher with 1 to 5 year teaching experience) teaching mathematics at X-Social Class was selected as the subject of this study. The data was collected by observing the teacher’s mathematical communication in facilitating and guiding a discussion with the rules of sinus as the teaching material, and it was followed by a deep interview. The result showed that the junior teacher facilitated and guided a class discussion include providing responses (answer) addressing students’ difficulties and providing chances for students to propose and explain their ideas and be active in discussion. The junior teacher provides responses at sharp, optimal, and specific manner. In addition, she provides chances for her students to explain their thinking and have a discussion in anticipative, observative, selective, and connective manner. However, the study found that some of high-school teachers develop mathematical communication skills and use them to develop students’ mathematical communication skills.

Impact of discussion on preferences elicited in a group setting

Milne Ruairidh

2006-03-01

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

2001-03-01

Purpose: To compare the indications for biopsy with and without the use of the Breast Imaging Reporting and Data System. Material and methods: Biopsies using the ABBI were performed in 62 patients with 64 non-palpable evident mammographic lesions. The initial decision for biopsy was made by non-radiologists due to suspicious microcalcifications (n=53) and masses (n=11). The indication was retrospectively reassessed by adopting the BI-RADS classification by three radiologists in consensus. The positive predictive value (PPV) of both indication strategies was assessed and compared. Results: Biopsies adopting ABBI were performed without major side-effects and were diagnostic. Carcinoma was present in 14 lesions: nine specimens were diagnosed as DCIS and five as invasive carcinomas. For the 50 benign lesions histology revealed mastopathies (26/50) and fibroadenomas (8/50) as the most frequent diagnosis. The positive predictive value (PPV) for the initial indication was 22%, whereas PPV for BI-RADS based indications (categories 4 and 5) was 31%. Conclusion: ABBI enables stereotactically-guided procedures that result in representative and diagnostic biopsies. Standardized criteria like BI-RADS improve the PPV and should be a mandatory part of mammographic evaluation. Radiologists should remain involved in the decision making. (orig.) [German] Ziel: Perkutane stereotaktische Biopsien mit dem ABBI stellen eine neue Alternative in der Abklaerung nicht palpabler Mammalaesionen dar.

Material und Methoden: Insgesamt wurde bei 62 Patientinnen mit 64 Laesionen eine Biopsie mit dem ABBI System durchgefuehrt. Die primaere Indikation zur ABBI Biopsie wurde von Nicht-Radiologen aufgrund von Mikrokalzifikationen in 53 Faellen und einer unklaren Verdichtung in 11 Faellen gestellt.

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.

Samplaski, Mary K

2018-01-01

To examine posts on Internet discussion groups related to vasectomies, and identify common ideas through a structured theme analysis. Internet discussion boards were identified using the search term "vasectomy." Three discussion boards were identified as having the most posts and were chosen for analysis. Using an iterative and structured analysis process, each post was analyzed using thematic analysis in 3 steps (open coding, axial coding, and selective coding) to determine common themes. A total of 129 posts were analyzed. The most common posts related to changes in sexual function after vasectomy. The second most common theme was pain after vasectomy. There were also posts about considerations before vasectomy, planning for postvasectomy care, what to expect after vasectomy, potential issues after vasectomy and how to manage these, and feelings about vasectomy. Some of the information present did not have a factual basis. Posts dedicated to postvasectomy pain and sexual dysfunction were of the highest quantity. There was no medical provider input to these discussion boards. Educational efforts should be targeted to these areas and should include a health-care professional. Copyright © 2017 Elsevier Inc.

Nakikj, Drashko; Mamykina, Lena

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.

Hoadley, Christopher M.

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.

Two NaNiCl{sub 2}-battery types including the battery controller and peripheral equipment have been developed for the application in fork lift trucks and driverless transportation. The batteries have been tested and evaluated on bench testing as well as in fork lift trucks and driverless trucks in practical application. The field tests have been performed by the subcontractors Still, Mercedes-Benz and Indumat. All test results have shown that the NaNiCl{sub 2}-battery (ZEBRA-battery) is well suited for the application in industrial traction. A series development together with a cost reduction programme have to be performed ahead of the introduction of the ZEBRA-battery into the market for industrial traction batteries. (orig.) [Deutsch] Im Rahmen des Vorhabens wurden zwei NaNiCl{sub 2}-Batterietypen, eine fuer die Anwendung in Gabelstaplern, die andere fuer den Einsatz in fahrerlosen Transportsystemen (FTS), einschliesslich des Batteriesteuergeraetes und der Batterieperipherie entwickelt. Die Batterien wurden auf Teststaenden im Labor sowie in Gabelstaplern und FTS unter Praxisbedingungen erprobt. Der praktische Einsatz erfolgte bei den Unterauftragnehmern Still, Mercedes-Benz und Indumat. Die Ergebnisse haben gezeigt, dass die NaNiCl{sub 2}-Batterie (ZEBRA-Batterie) fuer die Anwendung in Gabelstaplern und FTS geeignet ist. Insbesondere wurde nachgewiesen, dass die NaNiCl{sub 2}-Batterie im Gegensatz zu anderen Batteriesystemen einen Zweischichtbetrieb von Gabelstaplern ohne Batteriewechsel ermoeglicht. Vor Einfuehrung der ZEBRA-Batterie in den Flurfoerdermarkt muss die Serienentwicklung bei gleichzeitiger Senkung der Herstellkosten durchgefuehrt werden. (orig.)

Full text of publication follows: The nuclear business community is undergoing immense changes and challenges due to consolidation of the power industry and plant owners, shifts in the needs of plant owners, addition of new competitors, loss of old competitors, aging of the workforce, loss of personnel to competing industries, and the advances in electronic communications. These changes have significantly perturbed existing business models and relationships in the nuclear industry as well as the broader power, engineering, construction, equipment, and commodities fields. Vendors have responded to these challenges in a number of different ways. The participants for this panel have been selected from a diverse set of vendor organization types so that a broad spectrum of evaluation and approaches will be discussed. The participants in this panel discussion will provide insights into their views of the challenges to a successful nuclear business. They will provide insights into the expectations and approaches by each party in the client vendor relationship. Also discussed will be an overview of the strategies that each panelist views as potential success paths to nurture and grow the client-vendor relationship today with their insights into the future.

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.

To discuss illicit nuclear trafficking

Balatsky, Galya I [Los Alamos National Laboratory; Severe, William R [Los Alamos National Laboratory; Wallace, Richard K [Los Alamos National Laboratory

2010-01-01

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

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.

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.

Nuclear medicine offers a wide range of possibilities to investigate dementia. Various SPECT and PET tracers will be introduced in this article first. Different questions concerning evaluation of dementia are discussed taking Alzheimer's disease (AD) as an example. It is important to perform nuclear medicine investigations on high technical level, using standardized methods as statistical parametric mapping (SPM) for evaluation. If neuroprotective therapies are available, an early diagnosis, the determination of risk factors and longitudinal investigations will be the focus of interest and the main goal of nuclear medicine. Apart from measuring cerebral perfusion and glucose metabolism the development of new ligands, concerning the cholinergic system and the visualization of amyloid plaques, is of great importance. (orig.) [German] Nuklearmedizin bietet bei der Erfassung und Beurteilung eines dementiellen Prozesses eine Vielzahl von Untersuchungsmoeglichkeiten. Anhand des Morbus Alzheimer (DAT) werden in dem vorliegenden Artikel neben einer kurzen Schilderung der zur Verfuegung stehenden Methoden die verschiedenen nuklearmedizinisch relevante Fragestellungen angefuehrt, zu deren Beantwortung die funktionelle Bildgebung Informationen liefern kann. Durch den Einsatz bestimmter, standardisierter Auswerteverfahren wie statistical parametric mapping (SPM) ist es moeglich, entscheidende Hinweise zur Diagnose und Differenzialdiagnose der DAT zu erlangen. In Zukunft werden, insbesondere bei einer Verfuegbarkeit neuroprotektiver Therapien, eine moeglichst fruehe Diagnosestellung und die Erfassung von Risikofaktoren sowie die Moeglichkeit einer Verlaufsbeobachtung in den Mittelpunkt des Interesses und in das Zentrum nuklearmedizinischer Untersuchungen ruecken.

The ethics of research using electronic mail discussion groups.

Kralik, Debbie; Warren, Jim; Price, Kay; Koch, Tina; Pignone, Gino

2005-12-01

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

Panel discussion: In vivo pet modeling and data analysis

International Nuclear Information System (INIS)

Koeppe, R.A.

1991-01-01

Following the first afternoon session on in vivo PET modeling and data analysis, a panel assembled to discuss in greater detail some of the issues pertinent to the kinetic analysis of PET data. The discussion was opened with a comment on some of the diofficulties of PET imaging in the study of neurotransmitter and receptor systems, including resolution limitations, image distortions, and levels of nonspecific binding. Dr. Hutchins reiterated that the imaging distortions predicted by his simulation studies include both open-quotes scaleclose quotes and open-quotes shape open-quotes distortions. Then the panel discussed the issue of registration of functional (PET) and anatomic (MRI or CT) images. The use of an anatomic image as a road map or guide to where one is in the physiologic PET image is a very important part of performing PET studies. It is at least as important to align a dynamic PET sequence internally, from frame to frame, as it is to align the PET study to an anatomic study. If a dynamic imaging procedure will take 30-90 min or more, a method is needed to assure that the patient has not moved substantially during the procedure or that the movement can be accounted for. Several possibilities were discussed. The next topic considered the issue of model complexity versus model reduction. If a model is too complex, it cannot provide accurate estimates of the model parameters due to the lack of identifiability of individual parameters. Modeling approaches such as simplifying the model to two parameters and changing the experimental protocol to provide more information so model simplification is not necessary were discussed on the basis of the tradeoff between procedural complexity and quality of information

Some Themes in the Discussion of the Quality of Life

DEFF Research Database (Denmark)

Røpke, Inge

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...

Student decision making in large group discussion

Science.gov (United States)

Kustusch, Mary Bridget; Ptak, Corey; Sayre, Eleanor C.; Franklin, Scott V.

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.

Patients' willingness to discuss costs of treatment alternatives with their physicians is uncertain. To explore public attitudes toward doctor-patient discussions of insurer and out-of-pocket costs and to examine whether several possible communication strategies might enhance patient receptivity to discussing costs with their physicians. Focus group discussions and pre-discussion and post-discussion questionnaires. Two hundred and eleven insured individuals with mean age of 48 years, 51 % female, 34 % African American, 27 % Latino, and 50 % with incomes below 300 % of the federal poverty threshold, participated in 22 focus groups in Santa Monica, CA and in the Washington, DC metro area. Attitudes toward discussing out-of-pocket and insurer costs with physicians, and towards physicians' role in controlling costs; receptivity toward recommended communication strategies regarding costs. Participants expressed more willingness to talk to doctors about personal costs than insurer costs. Older participants and sicker participants were more willing to talk to the doctor about all costs than younger and healthier participants (OR = 1.8, p = 0.004; OR = 1.6, p = 0.027 respectively). Participants who face cost-related barriers to accessing health care were in greater agreement than others that doctors should play a role in reducing out-of-pocket costs (OR = 2.4, p = 0.011). Participants did not endorse recommended communication strategies for discussing costs in the clinical encounter. In contrast, participants stated that trust in one's physician would enhance their willingness to discuss costs. Perceived impediments to discussing costs included rushed, impersonal visits, and clinicians who are insufficiently informed about costs. This study suggests that trusting relationships may be more conducive than any particular discussion strategy to facilitating doctor-patient discussions of health care costs.

Identity Presentation: The Construction of Identity in Asynchronous Discussion

Directory of Open Access Journals (Sweden)

Brian Morgan

2008-08-01

Full Text Available This study examines the use of e-mail as a tool for long term discussion between teachers and grade six students. E-mail messages between grade six students and teachers were collected over the course of one academic year. Methods of conversation analysis within a framework of social practice are used to examine the data. While identity is more readily constructed and more fully developed in contexts which allow for physical embodiment such as face-to-face discussion, this analysis found that identity can be constructed in a context that does not provide for the physical embodiment of identity: Identity was constructed using the social, cultural, and technological tools provided and supported by e-mail to develop social practices germane to the e-mail discussion. This study has implications for further understanding the relation between identity, goals, constraints and affordances, and the collaborative creation of social practices in asynchronous computer mediated communication.

Vaccine Hesitancy in Discussion Forums: Computer-Assisted Argument Mining with Topic Models.

Science.gov (United States)

Skeppstedt, Maria; Kerren, Andreas; Stede, Manfred

2018-01-01

Arguments used when vaccination is debated on Internet discussion forums might give us valuable insights into reasons behind vaccine hesitancy. In this study, we applied automatic topic modelling on a collection of 943 discussion posts in which vaccine was debated, and six distinct discussion topics were detected by the algorithm. When manually coding the posts ranked as most typical for these six topics, a set of semantically coherent arguments were identified for each extracted topic. This indicates that topic modelling is a useful method for automatically identifying vaccine-related discussion topics and for identifying debate posts where these topics are discussed. This functionality could facilitate manual coding of salient arguments, and thereby form an important component in a system for computer-assisted coding of vaccine-related discussions.

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.

The power of words: discussing decision making and prognosis.

Dizon, Don S; Politi, Mary C; Back, Anthony L

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 discussion of the relativistic equal-time equation

International Nuclear Information System (INIS)

Chengrui, Q.; Danhua, Q.

1981-03-01

Ruan Tu-nan et al have proposed an equal-time equation for composite particles which is derived from Bethe-Salpeter (B-S) equation. Its advantage is that the kernel of this equation is a completely definite single rearrangement of the B-S irreducible kernel without any artificial assumptions. In this paper we shall give a further discussion of the properties of this equation. We discuss the behaviour of this equation as the mass of one of the two particles approaches the limit M 2 → infinite in the ladder approximation of single photon exchange. We show that up to order O(α 4 ) this equation is consistent with the Dirac equation. If the crossed two photon exchange diagrams are taken into account the difference between them is of order O(α 6 ). (author)

Round-table discussion on food irradiation

International Nuclear Information System (INIS)

1973-01-01

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.

Mathias, Clinton

2015-08-25

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.

Notes on a methodological discussion: autobiography, critique and time

Directory of Open Access Journals (Sweden)

Gunvor Løkken

2010-06-01

Full Text Available After having tried for some time to overview the contemporary field of qualitative research to give a lecture for a professorship in that area, my idea at the outset of writing this article was to address whether changes in qualitative research should be viewed as recurrent revolutions as highlighted by Denzin and Lincoln (2000; 2005, or as a field of continuing key themes and long-standing tensions, as conceptualized by Atkinson, Coffey and Delamont (2003. However, during my writing, after one detour into the May 2009 issue of Current Sociology and a second detour into the July 2009 issue of Qualitative Research, my attention focused on to how critical debate and review are displayed in different methodological positions of qualitative research. In my reading, the discussion in Current Sociology between main stream and postmodern methodological positioning revealed an utterly one-way feminist critique; this was also the case in one of three book reviews of The Handbook of Qualitative Research (Denzin and Lincoln, 2005 in the referred issue of Qualitative Research. My puzzle over this critical stance, and my third detour, into Yvonne Lincoln’s discussion of twenty-five years of qualitative and new paradigm research in the January 2010 Issue of Qualitative Inquiry, helped evolve the following notes on a methodological discussion.

Science.gov (United States)

Appleton, Jessica; Fowler, Cathrine; Brown, Nicola

2017-08-01

Childhood obesity is an increasing concern for parents and health professionals alike. Parents' perception of obesity as a current health issue for their children is important for the everyday parenting and health choices parents make. As parents are frequently going online to seek and exchange information about parenting and child health, asynchronous online discussion forums provide an opportunity to investigate their perceptions and concerns. Understanding parents' perceptions, beliefs and attitudes is important in any childhood obesity prevention and intervention. To explore parents' perceptions, perspectives and concerns regarding childhood obesity expressed on asynchronous online discussion forums. A qualitative descriptive approach using template analysis to analyse a novel data collection strategy of 34 purposefully sampled threads from two Australian-based asynchronous online discussion forums. Parents on the discussion forum displayed an understanding of childhood obesity as a public health concern, the discussion incorporated issues such as providing a healthy diet and lifestyle for children. Parents shared their own opinions and experiences that challenged or conceded to the status quo of the discussion. Parents discussed the role of health professionals in obesity prevention. There were varied opinions on the relevance of health professionals, particularly nurses, monitoring of growth and risk of obesity. This exploratory study highlights that parents perceive childhood obesity as an important public health concern, and that they understand the key public health messages of prevention and intervention. Yet, for many it is difficult to successfully implement these messages into their everyday lives. Health professionals need to play a key role in providing non-judgemental, innovative support and advice to parents to successfully implement prevention and intervention strategies.

ETHICS AND POLITICAL ACTION IN MARXISM: ELEMENTS FOR A CONTEMPORARY DISCUSSION

Full Text Available The present article attempts to discussions around the relationship between ethics and political activism within Marxism. Thus, we have chosen to discuss the theme from the classic texts of Marx and Gramsci. Despite the clear limitation of the number of authors discussed, it can be argued that the problems and solutions raised by Marx and Gramsci cross the Marxist debate in general, allowing therefore to glimpse some dilemmas and opportunities related to the central issue in the field.

Fuel ethanol discussion paper

International Nuclear Information System (INIS)

1992-01-01

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

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.

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

Pre-screening Discussions and Prostate-Specific Antigen Testing for Prostate Cancer Screening.

Science.gov (United States)

Li, Jun; Zhao, Guixiang; Hall, Ingrid J

2015-08-01

For many men, the net benefit of prostate cancer screening with prostate-specific antigen (PSA) tests may be small. Many major medical organizations have issued recommendations for prostate cancer screening, stressing the need for shared decision making before ordering a test. The purpose of this study is to better understand associations between discussions about benefits and harms of PSA testing and uptake of the test among men aged ≥40 years. Associations between pre-screening discussions and PSA testing were examined using self-reported data from the 2012 Behavioral Risk Factor Surveillance System. Unadjusted prevalence of PSA testing was estimated and AORs were calculated using logistic regression in 2014. The multivariate analysis showed that men who had ever discussed advantages of PSA testing only or discussed both advantages and disadvantages were more likely, respectively, to report having had a test within the past year than men who had no discussions (ptesting with their healthcare providers were more likely (AOR=2.75, 95% CI=2.00, 3.79) to report getting tested than men who had no discussions. Discussions of the benefits or harms of PSA testing are positively associated with increased uptake of the test. Given the conflicting recommendations for prostate cancer screening and increasing importance of shared decision making, this study points to the need for understanding how pre-screening discussions are being conducted in clinical practice and the role played by patients' values and preferences in decisions about PSA testing.

2016-03-01

Full Text Available The Internet affords users a unique and low-cost way to engage with news, politics, and one another. Although young people are the most likely age cohort to go online, it is questionable whether young people take advantage of the Internet as a deliberative space. We examine the way college students perceive the online world as a venue for political discussion by analyzing responses from six focus groups conducted with college students across the United States. Using deliberative theory as a guide, we examine focus group participants’ thoughts about political discussion both online and offline. Our findings indicate that young people’s preferences for online discussions about politics and the news consistently link to the ideals of deliberation. Young people prefer engaging with others who are knowledgeable and remain flexible and calm during discussions. Goals for engaging in conversations about politics primarily revolved around sharing information and opinions. Participants preferred civil discourse that focuses on commonalities rather than differences between people. This study provides greater insight into how the rising generation currently engages with politics and the news and reasons why many people hesitate to participate in online discussions about public affairs.

Venkatapuram's Capability theory of Health: A Critical Discussion.

Science.gov (United States)

Tengland, Per-Anders

2016-01-01

The discussion about theories of health has recently had an important new input through the work of Sridhar Venkatapuram. He proposes a combination of Lennart Nordenfelt's holistic theory of health and Martha Nussbaum's version of the capability approach. The aim of the present article is to discuss and evaluate this proposal. The article starts with a discussion of Nordenfelt's theory and evaluates Venkatapuram' critique of it, that is, of its relativism, both regarding goals and environment, and of the subjectivist theory of happiness used. Then the article explains why Nordenfelt's idea of a reasonable environment is not a problem for the theory, and it critiques Venkatapuram's own incorporation of the environment into the concept of health, suggesting that this makes the concept too wide. It contends, moreover, that Venkatapuram's alternative theory retains a problem inherent in Nordenfelt's theory, namely, that health is conceived of as a second-order ability. It is argued that health should, instead, be defined as first-order abilities. This means that health cannot be seen as a capability, and also that health cannot be seen as a meta-capability of the kind envisioned by Venkatapuram. It is, furthermore, argued that the theory lacks one crucial aspect of health, namely, subjective wellbeing. Finally, the article tries to illustrate how health, in the suggested alternative sense, as first-order abilities, fits into Nussbaum's capability theory, since health as an 'actuality' is part of all the 'combined capabilities' suggested by Nussbaum. © 2016 John Wiley & Sons Ltd.

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.

'Breaking Good News': Neurologists' experiences of discussing SUDEP with patients in Scotland.

Science.gov (United States)

Nisbet, Tom; Turbull, Sue; Mulhern, Sharon; Razvi, Saif

2017-05-01

Since the findings of a Fatal Accident Inquiry (FAI) in 2010, clinicians working in Scotland have been advised to discuss the risk of Sudden Unexpected Death in Epilepsy (SUDEP) with patients immediately or soon after a diagnosis of epilepsy is made. A thematic analysis was used to describe the experiences discussing SUDEP of 10 clinicians (six Consultant Neurologists and four Neurology Registrars) working in Scotland. Contrary to previous research, clinicians appear to be routinely discussing SUDEP in a standardized fashion with newly diagnosed patients and the FAI appears to have instigated this change in practice. Clinicians are ambivalent about the practice and whether this is a Breaking Bad News (BBN) experience. Clinicians appear to anticipate that patients will be anxious or distressed discussing SUDEP, despite their experiences that patients do not react this way. There are further concerns that the pressure to discuss SUDEP, as a result of the FAI, hinders effective communication of the SUDEP message. Implications for guideline development are discussed.

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.

The 'Magic Light': A Discussion on Laser Ethics.

Science.gov (United States)

Stylianou, Andreas; Talias, Michael A

2015-08-01

Innovations in technology and science form novel fields that, although beneficial, introduce new bio-ethical issues. In their short history, lasers have greatly influenced our everyday lives, especially in medicine. This paper focuses particularly on medical and para-medical laser ethics and their origins, and presents the complex relationships within laser ethics through a three-dimensional matrix model. The term 'laser' and the myth of the 'magic light' can be identified as landmarks for laser related ethical issues. These ethical issues are divided into five major groups: (1) media, marketing, and advertising; (2) economic outcomes; (3) user training; (4) the user-patient/client relationship; and (5) other issues. In addition, issues arising from two of the most common applications of lasers, laser eye surgery and laser tattoo removal, are discussed. The aim of this paper is to demonstrate that the use of medical and para-medical lasers has so greatly influenced our lives that the scientific community must initiate an earnest discussion of medical laser ethics.

ENDORSING REFLECTIVE TECHNIQUES TO PROLIFERATE STUDENTS’ INTERACTIONS AND UTTERANCES IN A DISCUSSION FORUM

Directory of Open Access Journals (Sweden)

Marwito Wihadi

2012-12-01

Full Text Available High Intermediate-2 students’ brief responses in a discussion forum cause a long-expected discussion last in a couple of minutes in mixed-ability classes, depicting a minority of students are overtly dominant, while others are precisely passive. What yields discussions endure immaturely stems from both unclear roles of participants and their inadequate techniques to expand both interactions and spoken discourse. Therefore, Teacher-researcher assigned each participant in a discussion group of three to put reflection into practice, referring to the self-selected and discussed topics. The data were gained through non-participant observations, in which the teacher-researcher observed and recorded a singled-out group. A sample recording was, subsequently, transcribed and analyzed regarding with the number of exchanges in a five-minute discussion intake and the number of content words that students generated. It was found that employing reflective techniques, students were able to keep a particular topic being discussed at full. As a result, the number of content words multiplied. These findings resulted classroom teachers in insightful use of reflective techniques as one of the ways to proliferate students’ benefits in a discussion forum. Adequately practiced, students would be able to employ the techniques preponderantly, multiplying interactions among discussion members.

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

Science.gov (United States)

1992-01-01

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

Discussing dementia-related behaviors during medical visits for people with Alzheimer's disease.

Hunsaker, Amanda E; Schmidt, Karen; Lingler, Jennifer H

2010-05-01

Research suggests that caregivers appreciate support from primary care physicians (PCPs) regarding dementia care; however, there remains a need for studies examining the role that PCPs play in behavior management. The purpose of this study was to quantitatively characterize the discussion on dementia-related behaviors (DRBs) during PCP visits and compare findings to an independently administered assessment of DRBs exhibited within a period of 4 weeks prior to the PCP visit. Twenty-five PCP visits of persons with dementia, in which caregivers coattended the visit, were audio-recorded and analyzed for occurrence of DRB discussion. Disruptive behaviors were reported by 80% of caregivers via independent assessment, yet discussed in 23% of medical visits. Dementia-related behavior discussion occurred in visits where caregivers independently reported significantly higher behavior frequency and behavior-related burden. Implications of findings for ways PCPs can assist the caregiver in behavior management are discussed.

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.

Accelerating Cleanup: Focus on 2006. Discussion draft

International Nuclear Information System (INIS)

1997-01-01

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)

Panel discussion: Chemistry aspects of pet radiotracers

International Nuclear Information System (INIS)

Kilbourn, M.R.

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

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.

1990-12-01

A summary of the discussion at the HIGH p T session is presented. There was a clear consensus at this session that Jets and Jet Phenomena in Relativistic Heavy Ion collisions would best be studied using leading particles, in the same way that these phenomena were originally mapped out in p-p collisions. The new topic of ''Jet Quenching in Nuclei'' was extensively discussed. It was clear that this proposed phenomenon could also be studied by measuring fragmentation functions in Deeply Inelastic Lepton-Nucleus Scattering; but there was controversy over whether the effect should be seen in proton-Nucleus reactions. Other hard-scattering phenomena, including ''Mini-jets,'' single particle inclusive production, the ''Cronin Effect,'' and direct photon production, are mentioned. 26 refs., 3 figs

In online communities, antisocial behavior such as trolling disrupts constructive discussion. While prior work suggests that trolling behavior is confined to a vocal and antisocial minority, we demonstrate that ordinary people can engage in such behavior as well. We propose two primary trigger mechanisms: the individual's mood, and the surrounding context of a discussion (e.g., exposure to prior trolling behavior). Through an experiment simulating an online discussion, we find that both negat...

Disgust discussed: introduction to the special section.

Science.gov (United States)

Pole, Nnamdi

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

Peer Observation of Rounds Leads to Collegial Discussion of Teaching.

Science.gov (United States)

Pierce, J Rush; Rendón, Patrick; Rao, Deepti

2018-01-01

Faculty in the Division of Hospital Medicine provide most of the clinical teaching for learners at our institution. The majority of these faculty are Assistant Professors with limited formal instruction in clinical teaching. Previous Divisional strategies to improve clinical teaching ability included discussion of effective teaching behaviors, developing written expectations for teaching faculty, and instituting seminars on effective clinical teaching. Heretofore, the Division had not utilized a direct observation exercise. We developed a direct observation exercise to encourage discussion of teaching techniques and contemplation of change. Using a social learning model, we developed a peer-to-peer observation followed by a nonevaluative discussion. We created a tool for describing teaching behaviors in 5 domains that were similar to or different from the usual behavior of the observing peer: learner presentations, team leadership, bedside teaching, professionalism, and other. After the observation, the observing and observed faculty met to discuss observed teaching behaviors. Both faculty members discussed and then recorded any teaching behaviors that they planned to adopt or change. We implemented this intervention in a 22-member Academic Division of Hospital Medicine at a tertiary care medical center in the United States. A high proportion were junior faculty and graduates of our residency program. We reviewed records of 28 of 31 observations that were completed during the initial 9-month period of implementation and later surveyed faculty. The exercise resulted in planned changes in teaching behaviors that included instituting new methods to improve teaching team leadership, triaging of patients seen on rounds, faculty behaviors during oral presentations, giving real-time feedback, use of technology and humor, demonstrating physical examination findings, and modeling professional behaviors. Faculty later reported adoption of new teaching behaviors that were

In online communities, antisocial behavior such as trolling disrupts constructive discussion. While prior work suggests that trolling behavior is confined to a vocal and antisocial minority, we demonstrate that ordinary people can engage in such behavior as well. We propose two primary trigger mechanisms: the individual's mood, and the surrounding context of a discussion (e.g., exposure to prior trolling behavior). Through an experiment simulating an online discussion, we find that both negative mood and seeing troll posts by others significantly increases the probability of a user trolling, and together double this probability. To support and extend these results, we study how these same mechanisms play out in the wild via a data-driven, longitudinal analysis of a large online news discussion community. This analysis reveals temporal mood effects, and explores long range patterns of repeated exposure to trolling. A predictive model of trolling behavior shows that mood and discussion context together can explain trolling behavior better than an individual's history of trolling. These results combine to suggest that ordinary people can, under the right circumstances, behave like trolls.

Methodological challenges in qualitative content analysis: A discussion paper.

Science.gov (United States)

Graneheim, Ulla H; Lindgren, Britt-Marie; Lundman, Berit

2017-09-01

This discussion paper is aimed to map content analysis in the qualitative paradigm and explore common methodological challenges. We discuss phenomenological descriptions of manifest content and hermeneutical interpretations of latent content. We demonstrate inductive, deductive, and abductive approaches to qualitative content analysis, and elaborate on the level of abstraction and degree of interpretation used in constructing categories, descriptive themes, and themes of meaning. With increased abstraction and interpretation comes an increased challenge to demonstrate the credibility and authenticity of the analysis. A key issue is to show the logic in how categories and themes are abstracted, interpreted, and connected to the aim and to each other. Qualitative content analysis is an autonomous method and can be used at varying levels of abstraction and interpretation. Copyright © 2017 Elsevier Ltd. All rights reserved.

Discussions about end-of-life care are often difficult for patients and clinicians, and inadequate communication poses a barrier to patients receiving the care they desire. To understand factors that facilitate end-of-life care discussions that guide interventions to improve care. We examined baseline data from an ongoing randomized trial to evaluate associations between patients' self-reported desire for, and occurrence of, discussions about end-of-life care and factors influencing these discussions. Factors included emotional symptoms and barriers and facilitators to discussions. The sample included patients with serious illness (n = 473) and their primary or specialty care clinicians (n = 128). Regression analyses were adjusted for confounders and clustered patients under clinicians. Patients who endorsed each of three barriers to discussions were less likely to have had a discussion with their clinician (P-values ranging from communication about end-of-life care is associated with patient factors including communication barriers and facilitators and symptoms of depression and anxiety. Understanding these factors may facilitate design of effective communication interventions. Copyright © 2016 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

2014-03-01

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.

2005-11-01

The spread and use of computer-games including (interactive) depictions of violence are considered a moral problem, particularly if played by children and youths. This essay expresses an opinion on H. Volper's (2004) demand of condemning certain contents by media ethics. At the same time, an overview on the spread and use of "violent games" by children and youths is offered. As a matter of fact, the share of these titles in the complete range must not be estimated too high, certain titles on the other hand are extremely wide-spread. Finally, Fritz's and Fehr's thesis of the cultural conflict "computer game" (2004) is discussed, demonstrated at the example of the discussion on the Internet, and on the basis of this thesis a mediating position between the two cultures including audience ethics (Funiok 1999) is presented.

Provincial export project review requirements (project justification, environmental impacts, socio-economic impact assessment) and proposed legislative changes are first reviewed. The concepts and objectives of value added, economic rent, opportunity costs, economic (benefit-cost) analysis, and socio-economic impact analysis are explained. Employment issues including unemployed labor, employment benefits, and regional and occupational considerations are then discussed, as well as transfers to various levels of government in the form of taxes, subsidies, resource royalties, and depletion costs. 8 refs., 4 tabs

Victims' barriers to discussing domestic violence in clinical consultations: a qualitative enquiry.

Science.gov (United States)

Othman, Sajaratulnisah; Goddard, Chris; Piterman, Leon

2014-05-01

Victims of domestic violence frequently attend health care facilities. In many cases, their abusive experience is neither disclosed nor discussed during clinical consultations. This study examined the barriers faced by women when discussing abuse with health care providers, specifically in cases involving Malaysian women with a history of domestic violence. A qualitative study using in-depth interviews was conducted with 10 women with a history of domestic violence residing at a shelter. Purposive sampling was conducted until data saturation. Using the grounded theory approach of analysis, themes that emerged from these interviews were then further analyzed to examine the barriers faced by these women. Women who experienced domestic violence faced multiple barriers while discussing their accounts of abuse with others. Values placed on the privacy of domestic violence; upholding the traditional gender roles; preserving the family unity; minimizing the abuse, the feeling of shame, self-blame; and fearing their abuser generally create internal barriers when discussing their encounters of abuse with health care providers. The perceived unknown role of health care professionals when dealing with patients experiencing domestic violence as well as the previous negative experiences in clinical consultations acted as external barriers for discussing abuse with health care providers. Women with domestic violence experiences faced internal and external barriers to discussing their abuse during clinical consultations. Physicians and health care providers must consider domestic violence in consultations with female patients. A good doctor-patient relationship that encompasses empathy, confidence, trust, support, assurance, confidentiality, and guidance can help patients with abusive backgrounds overcome these barriers, leading to the disclosure and discussion of their abusive encounters. Proper education, guidelines, and support for health care providers are required to help

Table talk: How mothers and adolescents across socioeconomic status discuss food.

Science.gov (United States)

Fielding-Singh, Priya; Wang, Jennifer

2017-08-01

This article reports findings from a qualitative study of food practices among families of differing socioeconomic circumstances. Using in-depth interviews from sixty-two families in the San Francisco Bay Area in 2015-2016, we find socioeconomic differences in how mothers and adolescents talk about food. Across SES, mothers and adolescents engage in discussions about healthy eating. However, these conversations are more commonplace and embedded within high-SES family life than among low-SES families. Beyond conversations about 1) healthy eating, the topics of 2) food quality and 3) price are discussed to varying degrees across SES. Within high-SES families, frequent discussions of healthy eating are paired with dialogue highlighting the importance of consuming higher quality food. Price is largely absent as a topic of conversation among high-SES families. On the other end of the socioeconomic spectrum, low-SES mothers and adolescents frequently engage in conversations about price when discussing food. Mentions of food quality are rare, but when they do occur, they underscore important trade-offs between food's healthiness, quality and price. Given prior research showing the impact of dialogue between parents and adolescents on adolescents' dietary behaviors, these findings help us understand how family discussions contribute to shaping adolescents' approaches to food. An important implication is that high-SES families' discussions of food quality may strengthen messages about healthy eating, while conversations about affordability within low-SES families may highlight financial barriers to healthy eating.

2013-09-01

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.

Discussing the possibility of observation of parity violation in heavy ion collisions

International Nuclear Information System (INIS)

Voloshin, Sergei A.

2000-01-01

It was recently argued that in heavy ion collisions the parity could be broken. This paper addresses the question of the possibility of the experimental detection of the effect. We discuss how parity violating effects would modify the final particle distributions and how one could construct variables sensitive to the effect, and which measurement would be the (most) conclusive. Discussing different observables we also discuss the question of whether the ''signals'' can be faked by ''conventional'' effects (such as anisotropic flow, etc.) and make estimates of the signals

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

1998-01-01

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

End of life discussion in an academic family health team in Kingston, Ontario, Canada

Reta French

2013-01-01

Full Text Available Background: End-of-life (EOL discussions remain difficult in non-terminal patients as death is often perceived as a taboo and uncertainty. However, the call for proper EOL discussions has recently received public attention and media coverage. Evidence also reveals that non-terminal patients are more satisfied with health-care encounters when EOL has been discussed. Objectives and Methods: The objective of this study was to explore the prevalence of EOL discussions in non-terminal adult patients, the perceived barriers to such discussions and suggested methods for improvement. A study mixed-methods study was performed by a group of PGY1 family medicine residents in an academic health team in Kingston, Ontario. Results: EOL discussion was performed in a very small proportion of non-terminal patient encounters. Compared with attending physicians, residents were less likely to discuss EOL issues and reported more perceived barriers. Conclusion: Our findings reflect the need for an early and open approach in conducting EOL discussion for non-terminal healthy patients.

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.

On May 13, 2014, a 1-hour panel discussion session titled "Gender-specific Regulatory Challenges to Product Approval" was held during the Academic Emergency Medicine consensus conference, "Gender-specific Research in Emergency Medicine: Investigate, Understand, and Translate How Gender Affects Patient Outcomes." The session sought to bring together leaders in emergency medicine (EM) research, authors, and reviewers in EM research publications, as well as faculty, fellows, residents, and students engaged in research and clinical practice. A panel was convened involving a representative from the Office of Women's Health of the U.S. Food and Drug Administration, two pharmaceutical executives, and a clinical EM researcher. The moderated discussion also involved audience members who contributed significantly to the dialogue. Historical background leading up to the session along with the main themes of the discussion are reproduced in this article. These revolve around sex- and gender-specific research, statistical analysis of sex and gender, clinical practice, financial costs associated with pharmaceutical development, adaptive design, and specific recommendations on the regulatory process as it affects the specialty of EM. © 2014 by the Society for Academic Emergency Medicine.

Energy summit discussions with Federal Chancellor Merkel - potential legislative consequences

International Nuclear Information System (INIS)

Heller, W.

2006-01-01

The energy summit discussions held by Federal Chancellor Merkel are to converge in a consistent energy policy concept by late 2007. The second summit held on October 9, 2006 was prepared by three working groups. Working Group 1 was to handle 'International Aspects', Working Group 2, the 'National Aspects of Energy Supply', and Working Group 3, finally, 'Research and Energy Efficiency'. The reports dealing with international aspects and with research and energy efficiency were in the focus of discussions at the summit. The report about national aspects had not yet reached the level of maturity required for discussion. None of the reports contained anything under the headings of 'Setting aside the Gorleben Moratorium' and 'Continued Exploration of the Salt Dome for a Repository' and 'Extension of the Plant Life of Our Nuclear Power Plants'. This sounds very easy and is urgently required, but it is neither announced nor seriously debated in politics. If these legislative measures were taken and the rhetoric about the broad energy mix turned into energy policy reality, many problems in climate protection, in energy supply continuity, and in competitive electricity supply could be solved more easily.

2016-08-01

Patients with brachial plexus injury (BPI) and their family members contribute to Internet discussion groups dedicated to BPI. We hypothesized that a thematic analysis of posts from BPI Internet discussion groups would reveal common themes related to the BPI patient experience, providing topics for patient education and counseling. Internet discussion boards were identified using the search term "brachial plexus injury support group" in Google, Bing, and Yahoo! search engines. Two discussion boards had substantially more posts than other Web sites and were chosen for analyses. Posts from January 1, 2015, through January 1, 2016, were examined. Using an iterative and established process, 2 investigators (M.T.M. and C.J.D) independently analyzed each post using thematic analysis in 3 steps (open coding, axial coding, and selective coding) to determine common themes. In this process, each post was reviewed 3 times. A total of 328 posts from the 2 leading discussion boards were analyzed. Investigators reached a consensus on themes for all posts. One central theme focused on emotional aspects of BPI. Four other central themes regarding information support were identified: BPI disease, BPI treatment, recovery after BPI treatment, and process of seeking care for BPI. Examination of posts on Internet support groups for BPI revealed recurring concerns, questions, and opinions of patients and their family members. The most common themes related to disease information, treatment, recovery, and the emotional element of BPI. These findings provide a helpful starting point in refining topics for patient education and support that are targeted on patients' interests and concerns.

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

Theoretical and experimental discussion of Ixion, a possible thermonuclear device

Energy Technology Data Exchange (ETDEWEB)

Boyer, K; Hammel, J E; Longmire, C L; Nagle, D; Ribe, F L; Riesenfeld, W B [Los Alamos Scientific Laboratory, University of California, Los Alamos, NM (United States)

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.

Discussion of the duality in three dimensional quantum field theory

Energy Technology Data Exchange (ETDEWEB)

Ma, Chen-Te, E-mail: yefgst@gmail.com

2017-05-10

We discuss the duality in three dimensional quantum field theory at infrared limit. The starting point is to use a conjecture of a duality between the free fermion and the interacting scalar field theories at the Wilson–Fisher fixed point. The conjecture is useful for deriving various dualities in three dimensions to obtain a duality web. The study is also interesting for understanding the dualities, or equivalence of different theories from the perspective of the renormalization group flow. We first discuss the “derivation” without losing the holonomy. Furthermore, we also derive these dualities from the mean-field study, and consider the extension of the conjecture or dualities at finite temperature.

Minutes of the Hampstead Clinic's Diagnostic Profile Research Group during a fifteen-month period (1964-1965) are reviewed and discussed. A wide range of topics were considered and discussed, with a special focus on the affective life, object relations, and ego function of atypical children in comparison to the early ego functions and differentiation of normal and neurotic children. These lively clinical and theoretical discussions and their implications for therapeutic work with a wide range of children, demonstrate the multifaceted leadership and contributions of Anna Freud as teacher, clinician, and thinker, and of the Hampstead Clinic as a major center for psychoanalytic studies.

2013-12-01

Initiating advance care planning (ACP) discussions in the home may prevent avoidable hospitalizations by elucidating goals of care. Area agencies on aging care managers (AAACMs) work in the home with high-risk consumers. To determine which AAACM characteristics contribute to an increased frequency of ACP discussions. Cross-sectional investigator-generated surveys administered to AAACMs at 3 AAAs in Ohio. Of 289 AAACMs, 182 (63%) responded. The more experience and comfort AAACMs felt with ACP discussions, the more likely they were to initiate ACP discussions. It may be necessary to build interactive educational experiences where, for example, AAACMs are asked to fill out their own advance directives and/or facilitate others in ACP discussions to improve experience and comfort with ACP discussions.

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

Science.gov (United States)

Palmer, Jerry K; Loveland, James M

2008-03-01

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

Hunsaker, Amanda E.; Schmidt, Karen; Lingler, Jennifer H.

2011-01-01

Research suggests that caregivers appreciate support from primary care physicians (PCPs) regarding dementia care; however, there remains a need for studies examining the role that PCPs play in behavior management. The purpose of this study was to quantitatively characterize the discussion on dementia-related behaviors (DRBs) during PCP visits and compare findings to an independently administered assessment of DRBs exhibited within a period of 4 weeks prior to the PCP visit. Twenty-five PCP visits of persons with dementia, in which caregivers coattended the visit, were audio-recorded and analyzed for occurrence of DRB discussion. Disruptive behaviors were reported by 80% of caregivers via independent assessment, yet discussed in 23% of medical visits. Dementia-related behavior discussion occurred in visits where caregivers independently reported significantly higher behavior frequency and behavior-related burden. Implications of findings for ways PCPs can assist the caregiver in behavior management are discussed. PMID:20147601

Full Text Available Ein 77-jähriger Patient war wegen manifester neurogener Claudicatio spinalis bei bekannter lumbaler Spinalkanalstenose in 3 Segmenten an einer auswärtigen Institution mit perkutanen interspinösen Implantaten versorgt worden, wonach sich die klinische Symptomatik nicht änderte. Erst die mikrochirurgische Dekompression und die Entfernung der Platzhalter führten zu einer deutlichen Besserung der Beschwerden und Verlängerung der schmerzfreien Gehstrecke. Anhand dieses Falles wird die Verwendung von interspinösen Platzhaltern beleuchtet. In der bisherigen klinischen Anwendung fehlen noch die Langzeitergebnisse. Eine korrekte Indikationsstellung zur Intervention bei Spinalkanalstenose ist Voraussetzung für ein zufriedenstellendes postoperatives Ergebnis.

Full Text Available In diesem Aufsatz werde ich zwei Tempora der Vergangenheit im Deutschen behandeln, das Doppelperfekt und das Doppelplusquamperfekt. Ein Grund dafür, gerade diese beiden Formen zu beschreiben, liegt darin, daß sie einerseits in den Grammatiken kaum berücksichtigt werden, in entsprechenden linguistischen Arbeiten aber einen neuen Aufschwung bekommen haben. Für die Beschreibung beziehe ich mich überwiegend auf die Arbeiten von HAUSER-SUIDA & HOPPE-BEUGEL (1972, EROMS (1984, THIEROFF (1992 und VATER (1994. Die Formen werden zuerst rein formal und dann in ihrer Bedeutung und Anwendung beschrieben, ergänzt durch Beispiele, die den oben genannten. Arbeiten entnommen wurden.

Full Text Available Ausgehend von der Notwendigkeit einer qualitativ-empirisch fundierten medienpädagogischen Professionsforschung erörtert der Beitrag, wie das Gruppendiskussionsverfahren für diesen Zweck nutzbar gemacht werden kann. Anhand der exemplarischen Rekonstruktion medienpädagogischer Orientierungsmuster von in der offenen Jugendarbeit tätigen Pädagogen/-innen mit Hilfe der dokumentarischen Methode wird die praktische Anwendung des Verfahrens demonstriert und kritisch reflektiert. Dabei wird u. a. deutlich, dass das Gruppendiskussionsverfahren gut geeignet ist, zur Schliessung existierender Lücken der medienpädagogischen Professionsforschung beizutragen und gleichzeitig einen vielversprechenden Ansatz zur Entwicklung einer regelmässig eingeforderten reflexiven Professionalisierung zu leisten vermag.

Discussion on the thermal conductivity enhancement of nanofluids

Science.gov (United States)

2011-01-01

Increasing interests have been paid to nanofluids because of the intriguing heat transfer enhancement performances presented by this kind of promising heat transfer media. We produced a series of nanofluids and measured their thermal conductivities. In this article, we discussed the measurements and the enhancements of the thermal conductivity of a variety of nanofluids. The base fluids used included those that are most employed heat transfer fluids, such as deionized water (DW), ethylene glycol (EG), glycerol, silicone oil, and the binary mixture of DW and EG. Various nanoparticles (NPs) involving Al2O3 NPs with different sizes, SiC NPs with different shapes, MgO NPs, ZnO NPs, SiO2 NPs, Fe3O4 NPs, TiO2 NPs, diamond NPs, and carbon nanotubes with different pretreatments were used as additives. Our findings demonstrated that the thermal conductivity enhancements of nanofluids could be influenced by multi-faceted factors including the volume fraction of the dispersed NPs, the tested temperature, the thermal conductivity of the base fluid, the size of the dispersed NPs, the pretreatment process, and the additives of the fluids. The thermal transport mechanisms in nanofluids were further discussed, and the promising approaches for optimizing the thermal conductivity of nanofluids have been proposed. PMID:21711638

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.

When contemplating tracheostomy placement in a pediatric patient, a family-physician conference is often the setting for the disclosure of risks and benefits of the procedure. Our objective was to compare benefits and risks of tracheostomy presented during family-physician conferences to an expert panel's recommendations for what should be presented. We conducted a retrospective review of 19 transcripts of audio-recorded family-physician conferences regarding tracheostomy placement in children. A multicenter, multidisciplinary expert panel of clinicians was surveyed to generate a list of recommended benefits and risks for comparison. Primary analysis of statements by clinicians was qualitative. Single-center PICU of a tertiary medical center. Family members who participated in family-physician conferences regarding tracheostomy placement for a critically ill child from April 2012 to August 2014. We identified 300 physician statements describing benefits and risks of tracheostomy. Physicians were more likely to discuss benefits than risks (72% vs 28%). Three broad categories of benefits were identified: 1) tracheostomy would limit the impact of being in the PICU (46%); 2) perceived obstacles of tracheostomy can be overcome (34%); and 3) tracheostomy optimizes respiratory health (20%). Risks fell into two categories: tracheostomy involves a big commitment (71%), and it has complications (29%). The expert panel's recommendations were similar to risks and benefits discussed during family conferences; however, they suggested physicians present an equal balance of discussion of risks and benefits. When discussing tracheostomy placement, physicians emphasized benefits that are shared by physicians and families while minimizing the risks. The expert panel recommended a balanced approach by equally weighing risks and benefits. To facilitate educated decision making, physicians should present a more extensive range of risks and benefits to families making this critical

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.

The on-going campaign Respect@CERN was re-launched this year on Tuesday 5 May with a discussion forum led by Alan Richter, an expert consultant in ethics and diversity. Seeing so many colleagues in the Council Chamber for this kick-off event was a clear indication of interest in the topic as well as a willingness to engage in promoting a respectful workplace. Now, the discussion continues through the dedicated website.   “Accelerating Respect @ CERN” was the thought-provoking title of the kick-off event of our campaign and, indeed, the speaker presented several ways of achieving workplace respect with a selection of models that provided us with a springboard for the conversation to start. Participants were invited through an interactive survey to consider four of the building blocks that serve to shape a respectful working place: swift and deep trust; awareness of possible unconscious bias; awareness of cultural differences in ways to address conflict; and an appreciative...
