Full Text Available Abstract Background: Lack of adherence to pharmacological treatment is one of the main causes of low control rates in hypertension. Objective: To verify treatment adherence and associated factors, as well as blood pressure (BP control in participants of the Resistant Hypertension Optimal Treatment (ReHOT clinical trial. Method: Cross-sectional study including all 109 patients who had completed the ReHOT for at least 6 months. We excluded those participants who failed to respond to the new recruitment after three phone contact attempts. We evaluated the BP control by ambulatory BP monitoring (ABPM; controlled levels: 24-hour systolic and diastolic BP < 130 x 80 mmHg and analyzed the patients' treatment adherence using the Morisky Medication Adherence Scale (MMAS questionnaire validated by Bloch, Melo, and Nogueira (2008. The statistical analysis was performed with the software IBM SPSS statistics 21.0. We tested the normality of the data distribution with kurtosis and skewness. The variables tested in the study are presented with descriptive statistics. Comparisons between treatment adherence and other variables were performed with Student's t test for independent variables and Pearson's chi-square or Fisher's exact test. To conduct analyses among patients considering adherence to treatment and BP control, we created four groups: G0, G1, G2, and G3. We considered a 5% significance level in all tests. Results: During the ReHOT, 80% of the patients had good BP control and treatment adherence. Of 96 patients reevaluated in the present study, only 52.1% had controlled hypertension when assessed by ABPM, while 31.3% were considered adherent by the MMAS. Regarding other ABPM measures, we observed an absence of a nocturnal dip in 64.6% of the patients and a white-coat effect and false BP control in 23% and 12.5%, respectively. Patients' education level showed a trend towards being a determinant factor associated with lack of adherence (p = 0

Lauesen, Søren

2018-01-01

[Context and motivation] Traditional requirements describe what the system shall do. This gives suppliers little freedom to use what they have already. In contrast, problem-oriented requirements describe the customer’s demands: what he wants to use the system for and which problems he wants...... to remove. The supplier specifies how his system will deal with these issues. The author developed the problem-oriented approach in 2007 on request from the Danish Government, and named it SL-07.

Full Text Available Introduction. Nowadays, increasing the motivation of future specialists’ to mastering general and special professional competences is one of the acute issues of the higher education system. Despite a wide-spread popularity and a considerable amount of studies on the problem connected with motivation of training in higher education institution, researchers have not dealt with a mechanism of start of a motivational impulse of professional self-determination and professionalizing such as participation of students in extra-curricular activities and events of professionally oriented format. At the same time, students can find many skills demanded in the chosen profession and practical experience only on condition of their active participation in extra-curricular activities, which allow them to expand and deepen knowledge of the chosen profession received during the classroom activities; to solidify separate blocks of theoretical material in an informal situation.The aims of the research presented in the article are the following: to identify and study the process of motivation to participation in the organization of extra-curricular activities and events of professional orientation among students of different university courses; to disclose the potential of similar work for formation of additional research, organizational, communicatory and other skills and abilities necessary for becoming a valuable specialist. Methodology and research methods. Analytical review and generalization of psychological, pedagogical and methodical literature on the considered problem was conducted at the initial stage of work. The methodological research base involves: conceptual substantive and procedural approaches to studying the phenomenon of motivation; David McClelland’s Human Motivation Theory; Participatory Management Theory; Active Training Theory.

Full Text Available In Latin America, citizen's discontent with representative institutions has been shown by many scholars during last two decades. Latin American citizens express a general sentiment of disengagement and distrust from politics and politicians. This fact has re-launched the debate on the convenience of social participation in the policy-making process, beyond and complementing the electoral mechanism. Though, there is a lack of evidence to establish under what conditions Latin American citizens decide (or not to participate in public affairs to contribute to solve those problems. Theoretically based on the seminal work of Albert Hirschman (1977, the current study uses public opinion data from Latinbarometer (2008 to find the factors that increase (voice and decrease (exit the probability of citizens to participate in collective actions.

Mental health court outcomes: a comparison of re-arrest and re-arrest severity between mental health court and traditional court participants.

Moore, Marlee E; Hiday, Virginia Aldigé

2006-12-01

Mental health courts have been proliferating across the country since their establishment in the late 1990's. Although numerous advocates have proclaimed their merit, only few empirical studies have evaluated their outcomes. This paper evaluates the effect of one mental health court on criminal justice outcomes by examining arrests and offense severity from one year before to one year after entry into the court, and by comparing mental health court participants to comparable traditional criminal court defendants on these measures. Multivariate models support the prediction that mental health courts reduce the number of new arrests and the severity of such re-arrests among mentally ill offenders. Similar analysis of mental health court completers and non-completers supports the prediction that a "full dose" of mental health treatment and court monitoring produce even fewer re-arrests.

Quebec's health network has undertaken large-scale organizational changes to ensure the continuity, accessibility, and quality of health care and services for the population. This article describes the optimal approach for making changes to the organization of care and work for patients, health care workers, and organizations. This participative action research was carried out by means of interviews and document analysis. One hundred participants were involved, describing a total of 34 projects for significant organizational change. Results include an optimal approach broken down into 4 phases, each of which includes steps, facilitating factors, and potential difficulties. The phases of this approach are: (1) sharing the vision, mission, and values of the organization and identifying the purpose and need underlying the change; (2) building alliances and validating the involvement of the various players; (3) conceptualizing and planning the project; and (4) implementing changes and continuing evaluation. It is possible to rise to the challenge of finding new approaches to organize care and work by giving way to participation, mobilization, and innovation.

Agir de manière appropriée: la participation des jeunes à l'aménagement

Full Text Available La réflexion sur l’éthique et la participation des jeunes et des enfants à l’aménagement comporte au moins deux dimensions : d’une part, les justifications d’une telle participation ; d’autre part, les problèmes que la pratique participative fait émerger et face auxquels les cadres de référence conventionnels (non participatifs ne sont pas toujours utiles. Le présent article aborde ces deux dimensions et explore leurs liens à la lumière de trois méthodes distinctes en matière de théorie morale, soit l’éthique déontologique, l’éthique conséquentialiste et l’éthique de la vertu. Sur la base d’une expérience participative d’aménagement inscrite dans le programme Grandir en Ville de l’UNESCO, certaines contradictions entre les principes d’une pratique participative avec des enfants et la manière dont les problèmes éthiques sont parfois gérés sont mises en évidence. Two dimensions can be considered in a reflection on the ethics of participatory design and planning with children and youth: on the one hand, the justifications of participation; on the other hand, the issues that participatory practice may raise and that may come out of traditional (non participatory frames of reference. This paper explores the relationship between these two dimensions in the light of three distinct methodological approaches in moral theory: deontological ethics, utilitarian ethics and virtue ethics. Drawing on the experience of a UNESCO-Growing Up in Cities project, the paper stresses some contradictions between the principles of participatory practice and how the ethical issues are sometimes managed.

We propose a superconducting spin-triplet valve, which consists of a superconductor and an itinerant magnetic material, with the magnet showing an intrinsic non-collinear order characterized by a wave vector that may be aligned in a few equivalent preferred directions under the control of a weak external magnetic field. Re-orienting the spiral direction allows one to controllably modify long-range spin-triplet superconducting correlations, leading to spin-valve switching behavior. Our results indicate that the spin-valve effect may be noticeable. This bilayer may be used as a magnetic memory element for cryogenic nanoelectronics. It has the following advantages in comparison to superconducting spin valves proposed previously: (i) it contains only one magnetic layer, which may be more easily fabricated and controlled; (ii) its ground states are separated by a potential barrier, which solves the "half-select" problem of the addressed switch of memory elements.

This study aimed to provide useful materials for the realization of healthy and happy welfare society through the re-socialization of the retired elderly by identifying the effect of the push factors in the leisure sports participation of the retired elderly on re-socialization and recovery resilience. To achieve the study purpose, 304 subjects over the age of 55 residing in Seoul and Gyeonggin among the retired elderly were selected by using the method of systematic stratified cluster random sampling. As research methods, questionnaire papers were used. The data were collected and data which were judged to be incomplete or unreliable in responses were excluded from the analysis. After inputting data which are available to analysis and SPSS 18.0 program was used for statistical techniques. In this, data were processed by factor analysis, correlation analysis, and multiple regression analysis. The study results that were obtained from this analysis are as follows: First, the psychological stability among the push factors in the leisure sports participation of the elderly had a significant effect on re-socialization, while health pursuit had a significant effect on personal exchange and economic activity among the sub-factors of re-socialization. Second, psychological stability among the push factors in the leisure sports participation of the retired elderly had a significant effect on recovery resilience; personal relationships had an effect on empathy skills, impulse control, and self-efficacy; and health pursuit had a significant effect on impulse control, optimism, and self-efficacy.

The active presence of workers in different workplaces is very significant; additionally, consider their physical health is so imperative. Moreover, distinguishing the effective factors that can increase the amount of workers’ physical health and persuade them to exercise is essential; also, lack of attention to them leads to several difficulties. In the study, focused on 400 workers who worked for the newspaper in Tehran, Iran. One questionnaire for assessing demographic factors and cultural capital sport oriented were used. Findings of the study showed that cultural capital sport oriented have significant relationship with workers’ participation. Also, body image determined as the first reason for sport among workers. In overall, the sport has a noticeable role in workers’ life and it can grow their mind and body health. In this regard, the head of workers should be developed some methods for introducing workers to the sport; likewise, determined valuable programs for them to increase physical power and growing muscles.

2015-08-25

This paper studies conditions influencing the generosity of wealthy people. We conduct incentivized experiments with individuals who have at least €1 million in their bank account. The results show that millionaires are more generous toward low-income individuals in a giving situation when the other participant has no power, than in a strategic setting, where the other participant can punish unfair behavior. Moreover, the level of giving by millionaires is higher than in any other previous study. Our findings have important implications for charities and financial institutions that deal with wealthy individuals.

Epitaxial growth of ReS2(001) thin film via deposited-Re sulfurization

Urakami, Noriyuki; Okuda, Tetsuya; Hashimoto, Yoshio

2018-02-01

In this paper, we present the formation of large-size rhenium disulfide (ReS2) films via the sulfurization of Re films deposited on sapphire substrates. The effects of sulfurization temperature and pressure on the crystal quality were investigated. A [001]-oriented single crystal of ReS2 films with 6 × 10 mm2 area was realized. By sulfurizing Re films at 1100 °C, ReS2 films with well-defined sharp interfaces to c-plane sapphire substrates could be formed. Below and above the sulfurization temperature of 1100 °C, incomplete sulfurization and film degradation were observed. The twofold symmetry of the monocrystalline in-plane structure composed of Re-Re bonds along with Re-S bonds pointed to a distorted 1T structure, indicating that this structure is the most stable atomic arrangement for ReS2. For a S/Re compositional ratio equal to or slightly lower than 2.0, characteristic Raman vibrational modes with the narrowest line widths were observed. The typical absorption peak of ReS2 can be detected at 1.5 eV.

Full Text Available The magnetic anisotropies and easy axes of magnetization at room temperature were determined, and the effects of rare-earth (RE ions were clarified for RE-based cuprates, RE-doped bismuth-based cuprates and RE-doped Bi-based cobaltite regarding the grain orientation by magnetic field. The easy axis, determined from the powder orientation in a static field of 10 T, depended qualitatively on the type of RE ion for all three systems. On the other hand, the magnetization measurement of the c-axis oriented powders, aligned in static or rotating fields, revealed that the type of RE ion strongly affected not only the directions of the easy axis but also the absolute value of magnetic anisotropy, and an appropriate choice of RE ion is required to minimize the magnetic field used for grain orientation. We also studied the possibility of triaxial grain orientation in high-critical-temperature superconductors by a modulated oval magnetic field. In particular, triaxial orientation was attempted in a high-oxygen-pressure phase of orthorhombic RE-based cuprates Y2Ba4Cu7Oy. Although the experiment was performed in epoxy resin, which is not practical, in-plane alignment within 3° was achieved.

Schmidt, Carissa J; Zimmerman, Marc A; Stoddard, Sarah A

2018-06-07

Exposure to violence (ETV) during adolescence has been associated with negative effects in later life, and may negatively affect an individual's future orientation. Future orientation has important health implications and warrants being studied. Yet, few researchers have examined how ETV affects an individual's future orientation as a young adult. The purpose of this study was to examine the indirect effect of ETV during adolescence on future orientation as a young adult through perceived stress. We also tested the moderating effect of family participation on the relationship between perceived stress and future orientation. Longitudinal data from a sample of 316 African American participants (42.10% male and 57.90% female, Mage = 14.76 at Wave 1) from low socioeconomic backgrounds recruited from a Midwestern school district were used in the analysis. Multigroup structural equation modeling (SEM) was used to test our hypotheses. Our findings indicated that greater ETV during adolescence is associated with higher levels of perceived stress and, in turn, a more negative outlook on one's future as a young adult. This indirect effect occurred for individuals with lower family participation, but was not evident for individuals with greater family participation. These findings provide important implications for youth development interventions. © Society for Community Research and Action 2018.

Efficient sunlight harvesting and re-directioning onto small areas has great potential for more widespread use of precious high-performance photovoltaics but so far intrinsic solar concentrator loss mechanisms outweighed the benefits. Here we present an antenna concept allowing high light absorption without high reabsorption or escape-cone losses. An excess of randomly oriented pigments collects light from any direction and funnels the energy to individual acceptors all having identical orientations and emitting ~90% of photons into angles suitable for total internal reflection waveguiding to desired energy converters (funneling diffuse-light re-directioning, FunDiLight). This is achieved using distinct molecules that align efficiently within stretched polymers together with others staying randomly orientated. Emission quantum efficiencies can be >80% and single-foil reabsorption energy funneling, dipole re-orientation, and ~1.5-2 nm nearest donor-acceptor transfer occurs within hundreds to ~20 ps. Single-molecule 3D-polarization experiments confirm nearly parallel emitters. Stacked pigment selection may allow coverage of the entire solar spectrum.

We consider the nature of the nematic to isotropic phase transition in terms of the molecular orientational re-ordering, expressed by the variation of the order parameter, s, in the light of Landau's theory of second order phase transition. Then, we show how the de Gennes modification to the Landau thermodynamic potential converts the transition to first order which is in better agreement with the experimental observations.

Future-Oriented Dairy Farmers’ Willingness to Participate in a Sustainability Standard: Evidence from an Empirical Study in Germany

Directory of Open Access Journals (Sweden)

Henrike Luhmann

2016-07-01

Full Text Available As a major agricultural subsector, milk production plays an important role in the EU 28. Political decisions such as the abolition of the milk quota system in 2015, highly volatile milk prices, high bargaining power of retailers and fierce international competition have led to challenges for both farmers and dairies and have created a need to improve competitiveness. Furthermore, the dairy sector is increasingly subject to societal demands for higher animal welfare and ecological standards. The concept of sustainability in the form of a production standard can be seen as a means for both dairy farmers and dairies to gain competitive advantages and meet stakeholders’ demands. Farmers’ willingness to participate in a sustainability standard is a key factor for its successful implementation. One attractive target group for such a standard are future-oriented farmers who plan to stay in dairy farming in the long run. This study, therefore, focuses on future-oriented dairy farmers and investigates their willingness to participate in a comprehensive sustainability standard. A hierarchical agglomerative cluster analysis is conducted to identify different groups based on their willingness to participate. 211 farmers can be categorized into three different clusters: ‘halfhearted sustainability proponents’, ‘highly dedicated sustainability proponents’ and ‘profit-oriented sustainability refusers’. Further analysis provides insights into the determinants of farmers’ willingness to participate in a sustainability standard. The results of this study provide manifold starting points for deriving managerial implications for the successful implementation of sustainability standards in European dairy farming

Orientalist Orientals: re-conceptualizing Ottoman architecture in the late Empire

Directory of Open Access Journals (Sweden)

Sibel Bozdogan

2015-12-01

Full Text Available Review of Ahmet Ersoy, Architecture and the Late Ottoman Historical Imaginary: Reconfiguring the Architectural Past in a Modernizing Empire: Late Ottoman Empire’s concerted effort to forge a modern imperial identity to better position itself within the emerging world system was accompanied by a proto-nationalist desire for an authentic cultural past. In the field of art and architecture, the result was a new interest and patriotic pride in the Islamic artistic and architectural heritage of the Empire, along with an intense period of creative engagement with European artistic and scholarly discourses. The book offers a meticulously historicized account of what emerged as a major intellectual effort to construct a genealogy for Ottoman architecture, to make it intelligible in terms of Western architectural theory and above all, to recast it as a historically evolving style capable of revival in the modern world. In doing so, it critically engages with recent scholarly debates on modernity, historicism, romanticism, orientalism, nationalism, revivalism, cosmopolitanism, authenticity, eclecticism and hybridity among other topics. Taking issue with both the received “westernization paradigm” and its companion, the notorious “decline thesis” in terms of which the architecture of Ottoman Tanzimat has long been written, it gives us a more complex, more nuanced, more cosmopolitan and more ambivalent picture. As such, it makes a major contribution to Ottoman/ Turkish studies, to the historiography of Islamic architecture and to cross-cultural studies in general.

Motives for physical exercise participation as a basis for the development of patient-oriented exercise interventions in osteoarthritis: a cross-sectional study.

Science.gov (United States)

Krauss, Inga; Katzmarek, Uwe; Rieger, Monika A; Sudeck, Gorden

2017-08-01

Physical exercises are effective in the treatment of osteoarthritis (OA). There is consensus that exercise interventions should take into account the patient's preferences and needs in order to improve compliance to exercise regimes. One important personal factor is the patient's motivation for physical exercise. Health improvement is a relevant motive for exercise participation. Accordingly, exercise interventions primarily focus on health related needs such as strengthening and pain reduction. However exercising provides further many-faceted incentives that may foster exercise adherence. The present study aimed to characterize target groups for person-tailored exercise interventions in OA according to the International Classification of Functioning and Disability and Health (ICF). Target groups should be classified by similar individual exercise participation motive profiles and further described by their disease-related symptoms, limitations and psychological determinants of exercise behavior. Observational study via self-administered questionnaires. Community. We enrolled 292 adults with hip/knee OA living independently of assistance. Participants completed the Bernese Motive and Goal Inventory in Leisure and Health Sports (BMZI), the Hannover Functional Ability Questionnaire for Osteoarthritis, the WOMAC-Index (pain/stiffness), the General Self-efficacy Scale and a questionnaire on perceived barriers to exercise participation. The BMZI-scales served as active variables for cluster analysis (Ward's method), other scales were used as passive variables to further describe the identified clusters. Four clusters were defined using five exercise participation motives: health, body/appearance, esthetics, nature, and contact. Based on the identified motive profiles the target groups are labelled health-focused sports people; sporty, nature-oriented individualists; functionalists primarily motivated by maintaining or improving health through exercise; and nature-oriented

Gender, level of participation, and type of sport: differences in achievement goal orientation and attributional style.

Science.gov (United States)

Hanrahan, Stephanie J; Cerin, Ester

2009-07-01

Findings regarding gender differences in achievement goal orientations and attributional style have been somewhat inconsistent. One possible explanation for varied findings is that potentially confounding variables such as level of participation and type of sport have not been considered. Athletes (108 males and 164 females) from team and individual sports, competing at recreational and competitive levels, completed the Task and Ego Orientation in Sport Questionnaire, the Sport Attributional Style Scale, and a demographic questionnaire. Athletes competing in individual sports had a higher ego orientation than those from team sports, and females scored higher in task orientation than males. Individual sport athletes made more internal, stable, and global, and less externally controllable attributions for positive events, and more internal attributions for negative events than team sport athletes. Competitive female athletes made less global attributions for positive events than did recreational female athletes. This difference was not observed in male athletes. Competitive individual, but not team, athletes made less global attributions than recreational individual athletes. The significant interactions regarding globality suggest that the tradition in sport psychology attribution research to focus solely on internality, stability, and controllability may be inadequate. From an applied perspective, sport psychologists and coaches may find it beneficial to target individual sport athletes and males for interventions designed to enhance task orientation. Similarly, team sport athletes may be appropriate as a focus for attribution retraining programs.

In a learned helplessness experiment, students were exposed to an academic failure situation and were then tested on a series of problem-solving tasks, either immediately after the pretreatment or after a delay of 24 hours. Performance and cognitive concomitants were measured during both experimental periods. Results demonstrated that action orientation was associated with self-immunizing cognitions during helplessness training. Action-oriented participants improved their performance level even after repeated failure feedbacks. Moreover, action-oriented students assigned to the delayed test condition responded with increased striving for success and showed performance increments, even in comparison with control subjects. In contrast, state-oriented participants developed symptoms of helplessness and showed impaired performance during failure inductions. In later tests on problem-solving tasks, state-oriented groups responded with increased fear of failure. Independent of immediate or delayed test conditions, they soon lapsed into new performance decrements.

Ottoni-Wilhelm, Mark; Estell, David B; Perdue, Neil H

2014-01-01

This study investigated the relationship between the monetary giving and volunteering behavior of adolescents and the role-modeling and conversations about giving provided by their parents. The participants are a large nationally-representative sample of 12-18 year-olds from the Panel Study of Income Dynamics' Child Development Supplement (n = 1244). Adolescents reported whether they gave money and whether they volunteered. In a separate interview parents reported whether they talked to their adolescent about giving. In a third interview, parents reported whether they gave money and volunteered. The results show that both role-modeling and conversations about giving are strongly related to adolescents' giving and volunteering. Knowing that both role-modeling and conversation are strongly related to adolescents' giving and volunteering suggests an often over-looked way for practitioners and policy-makers to nurture giving and volunteering among adults: start earlier, during adolescence, by guiding parents in their role-modeling of, and conversations about, charitable giving and volunteering.

de Almeida, Sandra Aparecida; Nogueira, Jordana de Almeida; Silva, Antonia Oliveira; Torres, Gilson Vasconcelos

2011-03-01

This qualitative research aims to analyze how sexual orientation has been incorporated into pedagogic practices through the point of view of educators from public schools of fundamental teaching. Twenty three educators from Cajazeiras, Paralba, Brazil participated in the study. The focus group was elected as technique of investigation, and the empirical data obtained were organized according to the technique of analysis of content. It was realized that there is an effort of the actors to privilege contents related to sexual orientation in the school environment though they demand that a level of informative and subjective character about the "sexuality" be encouraged providing the educators with a space for re-significations of its internality of values. The information directed to self-care must transcend the limits of prevention and hygienisation, incorporating extensive, inclusive and reflective methodologies, which recognize human and social rights and promote the ethical construction of citizenship.

In the current research, we examined whether re-inclusion (i.e. the change from a previous state of exclusion to a new state of inclusion) was perceived differently by people with individualistic and collectivistic cultural backgrounds. Individualists (German and Austrian participants) but not collectivists (Chinese participants) experienced re-inclusion differently than continued inclusion: While collectivistic participants did not differentiate between both kinds of inclusion, individualistic participants showed reduced fulfilment of their psychological needs under re-inclusion compared to continued inclusion. The results moreover revealed that only participants from individualistic cultures expressed more feelings of exclusion when re-included than when continually included. These exclusionary feelings partially mediated the relationship between the different states of inclusion and basic need fulfilment. © 2014 International Union of Psychological Science.

Moessbauer effects on oriented nuclei

International Nuclear Information System (INIS)

Sayouti, E.H.

1984-01-01

Standard nuclear orientation methods (not sensitive to the polarization) do not give information on the sign of the magnetic moment. Mossbauer effect separates right-hand and left-hand circularly polarized components, thus its detection on oriented nuclei (T approximately 10 mK) gives the sign of the magnetic moment of oriented state. In this thesis we applied this method to study the 3/2 - ground states of 191 Pt and 193 Os, which are in the prolate-oblate transition region, where assignement of experimental levels to theoretical states is often umbiguous. We show that for those nuclei the sign of the magnetic moment is the signature of the configuration, and its determination establishes the correspondance between experimental and theoretical levels [fr

Re-orienting crop improvement for the changing climatic conditions of the 21st century

2012-06-01

Full Text Available Abstract A 70% increase in food production is required over the next four decades to feed an ever-increasing population. The inherent difficulties in achieving this unprecedented increase are exacerbated by the yield-depressing consequences of climate change and variations and by the pressures on food supply by other competing demographic and socioeconomic demands. With the dwindling or stagnant agricultural land and water resources, the sought-after increases will therefore be attained mainly through the enhancement of crop productivity under eco-efficient crop production systems. ‘Smart’ crop varieties that yield more with fewer inputs will be pivotal to success. Plant breeding must be re-oriented in order to generate these ‘smart’ crop varieties. This paper highlights some of the scientific and technological tools that ought to be the staple of all breeding programs. We also make the case that plant breeding must be enabled by adequate policies, including those that spur innovation and investments. To arrest and reverse the worrisome trend of declining capacities for crop improvement, a new generation of plant breeders must also be trained. Equally important, winning partnerships, including public-private sector synergies, are needed for 21st century plant breeding to bear fruits. We also urge the adoption of the continuum approach to the management of plant genetic resources for food and agriculture as means to improved cohesion of the components of its value chain. Compellingly also, the National Agricultural Research and Extension System of developing countries require comprehensive overhauling and strengthening as crop improvement and other interventions require a sustained platform to be effective. The development of a suite of actionable policy interventions to be packaged for assisting countries in developing result-oriented breeding programs is also called for.

Determination of the specific site occupation of rare earth additions in Y17SM06Lu07Fe5O12 thin films by the orientation dependence of characteristic x-ray emissions

The orientation dependence of characteristic x-ray emissions have been used to determine specific site occupations of Rare Earth additions in epitaxially grown films of Y 1 7 Sm 0 6 Lu 0 7 Fe 5 O 12 . A theoretical formulation based on the assumption of highly localized inner shell excitations was used not only to predict specific site sensitive orientations, but also to refine experimentally observed data employing a constrained least squares analysis to give probabilities for the occupation of the RE additions in the different crystallographic sites. Thus, it has been shown that in this compound the preference for the RE additions is a predominantly octahedral occupation with a probability greater than or equal to 95%. Some of the assumptions and limitations of the technique have also been discussed

Full Text Available Former researches on the contribution of organized sport to antisocial and pro-social behavior of the young have yielded discordant and contradictory results. However, in the majority of researches, it was determined that active practice of sport has a different effect on psycho-social development of male and female participants. We have undertaken the research with the aim of examining whether there is a connection between the participation of the pupils of secondary school age in organized sport activities and their pro-social value orientation and aggressiveness, and, if there is, whether there are gender differences in that connection. The sample consisted of 300 pupils of secondary school (Mathematical High School in Belgrade, out of which 150 (49 female and 101 male regularly practice sport for more than two years, and 150 pupils (84 male and 66 female do not practice organized sport. The indicators of practicing sport are: the length of practicing sport activities, regularity and intensity of training, participation in contests and the kind of sport (individual or team sport. The following variables of pro-social orientation were examined: readiness for cooperation, caring for other people, social responsibility and empathy. Aggressiveness was examined through aggressive tendencies towards others. All variables were examined by the application of appropriate questionnaires and evaluation scales which were answered by the pupils themselves. The results have shown significant (although low, positive correlations between practicing sport and pro-social values, as well as the negative (low correlation between practicing sport and aggression, for both genders of students. Statistically significant differences were found between boys and girls regarding pro-social orientation (higher level in girls, as well as aggressiveness (higher levels in boys. Significant correlations were lower and more numerous in male than in female respondents.

Rotational transition frequencies for rhenium pentacarbonyl hydride were measured in the 4-10 GHz range using a Flygare-Balle type microwave spectrometer. The rotational constants and Re nuclear quadrupole coupling constants for the four isotopomers, (1) H187Re(CO)5, (2) H185Re(CO)5, (3) D187Re(CO)5, and (4) D185Re(CO)5, were obtained from the spectra. For the most common isotopomer, B(1)=818.5464(2) MHz and eq Q(187Re)=-900.13(3) MHz. The Re-H bond length (r0) determined by fitting the rotational constants is 1.80(1) Å. Although the Re atom is located at a site of near-octahedral symmetry, the quadrupole coupling is large due to the large Re nuclear moments. A 2.7% increase in Re quadrupole coupling was observed for D-substituted isotopomers, giving a rather large isotope effect on the quadrupole coupling. The Cax-Re-Ceq angle is 96(1)°, when all Re-C-O angles are constrained to 180°.

Although coronary artery bypass graft surgery has significant effects on reducing the symptoms of coronary artery disease, there is not enough knowledge and understanding of lived experience of patients after surgery. Understanding lived experience of this group of patients would be helpful for healthcare staff to provide better services to the patients. The aim of this study was to describe with a deeper understanding, the lived experiences of patients after Coronary Artery Bypass Graft Surgery. Using a hermeneutic phenomenological approach and a Van-Manen analysis method, in-depth semi-structured interviews were conducted with eleven participants who had lived experienced of at least six months post - coronary artery bypass graft surgery. Re-birth was the main theme that emerged in the process of data analysis. This theme was derived from four sub-themes including "feels younger", ''vigorous heart'', ''intrepid life'' and ''oriented to be healthy''. Life after a coronary artery bypass graft surgery is often appreciated as a re-birth by persons with these experiences as surgery did not only provide a feeling of wellness, but also added a sensation of youthfulness and improvement in the quality of life for these participants. In addition, they would actively participate in health promotional activities such as; adherence to medication and diet regimes, changes in lifestyle to maintain their health.

The search for superhard materials, driven by their widespread use in industrial applications, highlights one of the most difficult problems in the field of materials science: the accurate characterization of a material's intrinsic physical properties. This paper reports on the full elastic tensor of two polycrystalline isotropic specimens and one specimen of ReB{sub 2} consisting of highly oriented grains. The high-monocrystal bulk modulus value extracted from the grain-oriented specimen, measured by resonant ultrasound spectroscopy, validates the ultra-incompressibility of ReB{sub 2}. An observed hardness of 40 GPa and a Debye temperature of 731 K were calculated for the ReB{sub 2} crystal, confirming its superhard and super-stiff properties. All the measured moduli of the ReB{sub 2} grain-oriented crystal exceed the comparable ones for the polycrystal by amounts that cannot be explained by averaging over direction, which may reveal why recent measurements reported on ReB{sub 2} containing excess boron yield values that are not as hard or incompressible as the crystal.

2002-01-01

Two molybdenite samples from the Middle-Low Reaches of the Yangtze River were dated by both Os-Os and Re-Os methods. Os-Os and Re-Os dating give identical age results for the two samples. An experiment of step distillation of Os-Os method suggests that no isotopic fractionation is observed between fractions obtained by the experiment. The results prove that the Os-Os method can avoid the problems in the Re-Os method, simplify the experimental procedure, give creditable age data, and have unique advantage that no quantitative extracting of Os is required

The Limits to Giving Back

Directory of Open Access Journals (Sweden)

Jade S. Sasser

2014-07-01

Full Text Available In this thematic section, authors consider the limitations on giving back that they faced in field research, or saw others face. For some authors, their attempts at giving back were severely limited by the scope of their projects, or their understandings of local cultures or histories. For others, very specific circumstances and historical interventions of foreigners in certain places can limit how and to what extent a researcher is able to have a reciprocal relationship with the participating community. Some authors, by virtue of their lesser positions of power relative to those that they were studying, simply decided not to give back to those communities. In each article it becomes apparent that how and in what ways people give back is unique (and limited both to their personal values and the contexts in which they do research.

Solange Maria Teixeira

2007-05-01

Full Text Available This text indicates essential elements needed for an analysis of direct democracy, materialized in processes of decentralization and civil society participation in spaces for deliberating public policies, in a context of reform of these policies in the 1990’s. It analyzes the national Policy for the Elderly and the experiences of elderly rights councils. It concludes that despite the fact that spaces for participation are contradictory and the orientations of participation of the various subjects are in conflict, the correlation of forces favorable to conservative forces, redirect social policies, giving them a new rationality and new legitimacy that distribute responsibilities to civil society. These changes reinforce a culture of privation in light of the clashes of the refractions of the social issue and transmute popular participation into consent and legitimization of the given order.

Full Text Available This study examines the empirical link between three dimensions of market orientation, namely, stu­dent orientation, competitor orientation and inter-functional coordination, and overall private uni­ver­sity per­formance in Kopertis X. It was based on an empirical investigation of private universities located in In­do­nesia’s provinces of West Sumatera, Riau, Jambi, and Kepulauan Riau. The primary data for the study were collected from a self-administered mail survey of 237 questionnaires from the private university re­sul­­ting in a sample of 114 usable responses being returned. From the application of the multiple re­gres­sion ana­lysis it was concluded that all three dimensions of market orientation had a significant impact on private un­iversity performance. Student orientation as a predictor variable is the strongest predictor of pri­vate uni­ver­­sity performance and followed by competitor orientation, and inter-functional coordination.

We re-order the long list factors according to how essential, important, and unique they are and discuss their significance and interrelationships. It is argued that bureacratic structure and operational modes are basically in conflict with features of successful PP programs (openness, two-way education, communication with nonexpert outsiders). If this is so, then it is not surprising that the factors essential for PP success in bureacracies involve extraordinary management efforts by agencies to bypass, compensate for, or overcome structural constraints. We conclude by speculating about the long-term viability of PP practices in the agency setting as well as the consequences for agencies that attempt the problematic task of introducing PP into their complex, mission-oriented organizations

Extracurricular participation and the development of school attachment and learning goal orientation: the impact of school quality.

Science.gov (United States)

Fischer, Natalie; Theis, Désirée

2014-06-01

School motivation and attachment typically decline after the transition to middle school. According to the stage-environment fit approach, extracurricular activities are supposed to promote motivation. However, research has shown that the effects depend on the quality of the activities, which usually is measured by assessing students' individual perceptions. This article adds to previous studies in examining effects of school-based extracurricular participation on the development of individual motivation (learning goal orientation) and school attachment depending on the quality of the activities (i.e., amounts of challenge and social support) at the school level. We focused on the motivation development of 3,230 students at 98 schools who filled in questionnaires in Grades 5 (2005), 7 (2007), and 9 (2009). The quality of extracurricular activities was assessed on the basis of responses from 4,270 students in Grades 5, 7, and 9 at the same schools at the first measurement point (2005). Thus, individual development of the longitudinal sample was predicted by aggregated quality measures at the school level. Three-level hierarchical linear growth-curve models including school level, student level, and time were calculated. Cross-level interactions were analyzed to examine the influence of extracurricular participation on individual development as a function of school quality. Results show that the effects of extracurricular participation on the development of learning goal orientation are dependent on both features of school quality, whereas the development of school attachment in particular is influenced by activities offering social support. Thus, the effects of extracurricular activities are based not only on individual perceptions of activity features but also on school quality.

Norm, gender, and bribe-giving: Insights from a behavioral game.

Directory of Open Access Journals (Sweden)

Tian Lan

Full Text Available Previous research has suggested that bribery is more normative in some countries than in others. To understand the underlying process, this paper examines the effects of social norm and gender on bribe-giving behavior. We argue that social norms provide information for strategic planning and impression management, and thus would impact participants' bribe amount. Besides, males are more agentic and focus more on impression management than females. We predicted that males would defy the norm in order to win when the amount of their bribe was kept private, but would conform to the norm when it was made public. To test this hypothesis, we conducted two studies using a competitive game. In each game, we asked three participants to compete in five rounds of creative tasks, and the winner was determined by a referee's subjective judgment of the participants' performance on the tasks. Participants were allowed to give bribes to the referee. Bribe-giving norms were manipulated in two domains: norm level (high vs. low and norm context (private vs. public, in order to investigate the influence of informational and affiliational needs. Studies 1 and 2 consistently showed that individuals conformed to the norm level of bribe-giving while maintaining a relative advantage for economic benefit. Study 2 found that males gave larger bribes in the private context than in the public, whereas females gave smaller bribes in both contexts. We used a latent growth curve model (LGCM to depict the development of bribe-giving behaviors during five rounds of competition. The results showed that gender, creative performance, and norm level all influence the trajectory of bribe-giving behavior.

To understand the underlying process, this paper examines the effects of social norm and gender on bribe-giving behavior. We argue that social norms provide information for strategic planning and impression management, and thus would impact participants' bribe amount. Besides, males are more agentic and focus more on impression management than females. We predicted that males would defy the norm in order to win when the amount of their bribe was kept private, but would conform to the norm when it was made public. To test this hypothesis, we conducted two studies using a competitive game. In each game, we asked three participants to compete in five rounds of creative tasks, and the winner was determined by a referee's subjective judgment of the participants' performance on the tasks. Participants were allowed to give bribes to the referee. Bribe-giving norms were manipulated in two domains: norm level (high vs. low) and norm context (private vs. public), in order to investigate the influence of informational and affiliational needs. Studies 1 and 2 consistently showed that individuals conformed to the norm level of bribe-giving while maintaining a relative advantage for economic benefit. Study 2 found that males gave larger bribes in the private context than in the public, whereas females gave smaller bribes in both contexts. We used a latent growth curve model (LGCM) to depict the development of bribe-giving behaviors during five rounds of competition. The results showed that gender, creative performance, and norm level all influence the trajectory of bribe-giving behavior.

The effect of human foetal heart geometry and anisotropy on anatomy induced drift and self-termination of cardiac re-entry is studied here in MRI based 2D slice and 3D whole heart computer simulations. Isotropic and anisotropic models of 20 weeks of gestational age human foetal heart obtained from 100μm voxel diffusion tensor MRI data sets were used in the computer simulations. The fiber orientation angles of the heart were obtained from the orientation of the DT-MRI primary eigenvectors. In a spatially homogeneous electrophysiological monodomain model with the DT-MRI based heart geometries, cardiac re-entry was initiated at a prescribed location in a 2D slice, and in the 3D whole heart anatomy models. Excitation was described by simplified FitzHugh-Nagumo kinetics. In a slice of the heart, with propagation velocity twice as fast along the fibres than across the fibers, DT-MRI based fiber anisotropy changes the re-entry dynamics from pinned to an anatomical re-entry. In the 3D whole heart models, the fiber anisotropy changes cardiac re-entry dynamics from a persistent re-entry to the re-entry self-termination. The self-termination time depends on the re-entry’s initial position. In all the simulations with the DT-MRI based cardiac geometry, the anisotropy of the myocardial tissue shortens the time to re-entry self-termination several folds. The numerical simulations depend on the validity of the DT-MRI data set used. The ventricular wall showed the characteristic transmural rotation of the helix angle of the developed mammalian heart, while the fiber orientation in the atria was irregular.

DNA/MVA Vaccination of HIV-1 Infected Participants with Viral Suppression on Antiretroviral Therapy, followed by Treatment Interruption: Elicitation of Immune Responses without Control of Re-Emergent Virus.

Full Text Available GV-TH-01, a Phase 1 open-label trial of a DNA prime—Modified Vaccinia Ankara (MVA boost vaccine (GOVX-B11, was undertaken in HIV infected participants on antiretroviral treatment (ART to evaluate safety and vaccine-elicited T cell responses, and explore the ability of elicited CD8+ T cells to control viral rebound during analytical treatment interruption (TI. Nine men who began antiretroviral therapy (ART within 18 months of seroconversion and had sustained plasma HIV-1 RNA <50 copies/mL for at least 6 months were enrolled. Median age was 38 years, median pre-ART HIV-1 RNA was 140,000 copies/ml and mean baseline CD4 count was 755/μl. Two DNA, followed by 2 MVA, inoculations were given 8 weeks apart. Eight subjects completed all vaccinations and TI. Clinical and laboratory adverse events were generally mild, with no serious or grade 4 events. Only reactogenicity events were considered related to study drug. No treatment emergent viral resistance was seen. The vaccinations did not reduce viral reservoirs and virus re-emerged in all participants during TI, with a median time to re-emergence of 4 weeks. Eight of 9 participants had CD8+ T cells that could be stimulated by vaccine-matched Gag peptides prior to vaccination. Vaccinations boosted these responses as well as eliciting previously undetected CD8+ responses. Elicited T cells did not display signs of exhaustion. During TI, temporal patterns of viral re-emergence and Gag-specific CD8+ T cell expansion suggested that vaccine-specific CD8+ T cells had been stimulated by re-emergent virus in only 2 of 8 participants. In these 2, transient decreases in viremia were associated with Gag selection in known CD8+ T cell epitopes. We hypothesize that escape mutations, already archived in the viral reservoir, plus a poor ability of CD8+ T cells to traffic to and control virus at sites of re-emergence, limited the therapeutic efficacy of the DNA/MVA vaccine.clinicaltrials.gov NCT01378156.

Birth order, sibling sex ratio, handedness, and sexual orientation of male and female participants in a BBC internet research project.

Science.gov (United States)

Blanchard, Ray; Lippa, Richard A

2007-04-01

This study investigated the relations among sexual orientation, fraternal birth order (number of older brothers), and hand-preference. The participants were 87,798 men and 71,981 women who took part in a Web-based research project sponsored by the British Broadcasting Corporation (BBC). The results yielded some evidence confirming prior findings that non-right-handedness is associated with homosexuality in men and women, that older brothers increase the odds of homosexuality in men, and that the effect of older brothers on sexual orientation is limited to right-handed men. The evidence was weaker than in previous studies, however, probably because the usual relations among the variables of interest were partially obscured by the effects of other factors. Thus, the homosexual men and women had higher rates of non-right-handedness than their heterosexual counterparts, but the strongest handedness finding for both sexes was a marked tendency for participants who described themselves as ambidextrous also to describe themselves as bisexual. The birth order data were strongly affected by a tendency for the male participants to report an excess of older sisters, and the female participants to report an excess of older brothers. Statistical analyses confirmed that this was an artifact of the parental stopping rule, "Continue having children until you have offspring of both sexes." In subsequent analyses, participants were divided into those who did and did not have younger siblings, on the grounds that the data of the former would be less contaminated by the stopping rule. In the former subsample, the right-handed homo/bisexual males showed the typical high ratio of older brothers to older sisters, whereas the non-right-handed homo/bisexual males did not.

Low-temperature nuclear orientation

International Nuclear Information System (INIS)

Stone, N.J.; Postma, H.

1986-01-01

This book comprehensively surveys the many aspects of the low temperature nuclear orientation method. The angular distribution of radioactive emissions from nuclei oriented by hyperfine interactions in solids, is treated experimentally and theoretically. A general introductory chapter is followed by formal development of the theory of the orientation process and the anisotropic emission of decay products from oriented nuclei, applied to radioactive decay and to reactions. Five chapters on applications to nuclear physics cover experimental studies of alpha, beta and gamma emission, nuclear moment measurement and level structure information. Nuclear orientation studies of parity non-conservation and time reversal asymmetry are fully described. Seven chapters cover aspects of hyperfine interactions, magnetic and electric, in metals, alloys and insulating crystals, including ordered systems. Relaxation phenomena and the combined technique of NMR detection using oriented nuclei are treated at length. Chapters on the major recent development of on-line facilities, giving access to short lived nuclei far from stability, on the use of nuclear orientation for thermometry below 1 Kelvin and on technical aspects of the method complete the main text. Extensive appendices, table of relevant parameters and over 1000 references are included to assist the design of future experiments. (Auth.)

Mixing of multi-modal images for conformational radiotherapy: application to patient re positioning; Fusion d`images multi-modales pour la radiotherapie conformationnelle: application au repositionnement du patient

Energy Technology Data Exchange (ETDEWEB)

Vassal, P

1998-06-29

This study shows a procedure of patient re positioning by comparative evaluation between the position of the patient and the theoretical expected position of the patient; the stagger between the two information gives the error of installation in translation and rotation. A correction is calculated and applied to the treatment environment (position and orientation of the patient, position and orientation of the irradiation source). The control system allows to determine the precise position of the tumor volume. The echography allows to determine the position of an organ.The surface captor is used to localize the tumors of the face or of the brain, with the respect to the face, the acquisition and the treatment of information take only few minutes. The X rays imager is applied for the localization of bones structures. (N.C.)

Few studies have been conducted to assess the quality of orientation practices for ethics advisory committees that conduct ethics consultation. This survey study focused on several Harvard teaching hospitals, exploring orientation quality and committee members' self-evaluation in the American Society of Bioethics and Humanities (ASBH) ethics consultation competencies. We conducted a survey study that involved 116 members and 16 chairs of ethics advisory committees, respectively (52% and 62.5% response rates). Predictor variables included professional demographics, duration on committees and level of training. Outcome variables included familiarity with and preparedness in the ASBH competencies and satisfaction with orientations. We hypothesised that responses would be associated with both the aforementioned predictors and whether or not participants had encountered the ASBH competencies in training. A majority of respondents found their orientation curricula to be helpful (62%), although a significant portion of respondents did not receive any orientation (24%) or were unsatisfied with their orientation (14%). Familiarity with ASBH competencies was a statistically significant predictor of respondents' self-evaluation in particular categories (54% had heard of the competencies). Standard educational materials were reported as offered during orientation, such as readings (50%) and case studies (41%); different medium resources were less evidenced such as videos on ethics consultation (19%). Institutions should re-evaluate orientation practices for ethics committee members that perform ethics consultation. Integrating ASBH competencies and useful methods into a resourceful pedagogy will help improve both member satisfaction with orientation and preparation in consultation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Synthesis of ReN3 Thin Films by Magnetron Sputtering

Directory of Open Access Journals (Sweden)

G. Soto

2014-01-01

Full Text Available In this work ReNx films were prepared by reactive magnetron sputtering at room temperature and deposited on a silicon wafer. It was found that the diffractograms of the nitrogen-rich rhenium film are consistent with those produced by high-pressure high-temperature methods, under the assumption that the film is oriented on the substrate. Using density functional calculations it was found that the composition of this compound could be ReN3, instead of ReN2, as stated on previous works. The ReN3 compound fits in the Ama2 (40 orthorhombic space group, and due to the existence of N3 anions between Re layers it should be categorized as an azide. The material is exceptionally brittle and inherently unstable under indentation testing.

The study purpose was to contribute to a more complete understanding of the experience and meaning of family inheritance. The aim of this article is to describe and discuss the meaning of communication in inheritance experiences among Canadian families. A constructivist/interpretive methodological approach guided this research. Participants were recruited through purposive, convenience sampling from two cities and one town in southern and southwestern Ontario, Canada. Fifty face-to-face, semi-structured, audio-taped, in-depth interviews were conducted between June 2006 and April 2007. NVivo software was used to organize and analyze the data. A content analysis method guided data analysis. Participants interpreted the meaning of family structure, relationships, feelings, and past inheritance experiences to construct their family inheritance communication. Analysis of the findings revealed four themes regarding the role of communication in family inheritance including: (a) avoiding conflict and preserving biological ties , (b) resisting conversations about possessions , (c) achieving confidence with possession communication , and (d) lasting effects. Participants from non-blended and blended families experienced similar inheritance communication challenges related to past experience with their parents' wills and distribution of their own possessions. Participants with past positive inheritance experiences with parents adopted similar strategies when communicating their own inheritance wishes. Negative messages conveyed to participants by their parent's wills inspired participants to communicate in opposite ways in their own inheritance planning. The study findings are useful for gerontologists, lawyers, family counselors, and estate planners.

Sustainable development and social learning: Re-contextualising the space of orientation

Science.gov (United States)

Seddon, Terri

2016-10-01

In the lead-up to the 2007 Australian federal election, Labor candidate Kevin Rudd described climate change as the "great moral challenge of our generation". In the years since then, the heat in Australia has been rising - in terms of both temperature and climate politics -, but government action has slowed down. Endorsement of economic growth is prioritised, with only intermittent recognition of environmental costs. At grassroots level, citizens' attitudes are influenced by social norms. This kind of social learning is a major constraint on sustainability. Therefore, it seems useful to consider how educators might help build sustainable futures. To understand how historical context entangles social learning in ways that complicate policies associated with Education for Sustainable Development (ESD) and practices of Education for Sustainability (EfS), the author of this paper draws on the concept of "space of orientation". Focusing on adult education, she traces the contradiction between "globalisation" and "sustainability" through policy logics, relational practices in Australian adult education and the "necessary utopia" which provides a point of reference for making futures. She argues that spaces of orientation are a critical resource in this era of intensifying conflicts of interest between economic priorities of globalisation and environmental priorities intended to slow global warming, because they mediate context and orient learning in ways that clear a path towards sustainability through the entangled histories of this present.

Effect of mixing RE elements (Nd, Sm, Gd, Eu, Y, Yb) on the RE2BaCuO5/Nd4-2xBa2+2xCu2-xO10-2x phases in RE cuprate high-Tc superconductors

The phases RE 2 BaCuO 5 /RE 4 Ba 2 Cu 2 O 10 phases (where RE is a mixture of Nd, Sm, Gd, Eu, Y and Yb) have been synthesized in an oxygen atmosphere and subsequently characterized. The mixing of RE elements which inherently form the RE 2 BaCuO 5 phase through the peritectic decomposition of REBa 2 Cu 3 O 7-x (RE123) (i.e. Sm, Gd, Eu, Y, Yb), was observed to give homogeneous mixing of the elements in the 211 phase. In contrast it was found that on mixing Nd with other RE elements a mixture of the Nd 4-2x Ba 2+2x Cu 2-x O 10-2x (Nd422) and RE 2 BaCuO 5 (RE211) phases resulted. It was also observed that on mixing Nd with other REs a finite amount of the RE is substituted into the Nd422 phase and Nd into the RE211. (author)

Evaluation of Thermal Creep and Hydride Re-orientation Properties of High Burnup Spent Fuel Cladding under Long Term Dry storage

Energy Technology Data Exchange (ETDEWEB)

Kamimura, K [JNES (Japan)

2012-07-01

In Japan, spent fuels will be reprocessed as recyclable energy source at a reprocessing plant. The first commercial plant is under-constructing and will start operation in 2008. It is necessary that spent fuels should be stored in the independent interim storage facilities (ISF) until reprocessing. Utilities plan the operation of the first ISF in 2010. JNES has a mission to support the safety body by researching the data of technical standard and regulation. Investigating of spent fuel integrity during long term dry storage is one of them. The objectives are: 1) Evaluation of the effects of material design changes on creep properties of high burnup spent fuel cladding; 2) Evaluation of the effects of alloy elements and texture of irradiated Zircaloy on hydride re-orientation properties and the effects of radial hydrides on cladding mechanical properties; 3) Evaluation of the effects of temperature on irradiation hardening recovery.

Intricate Resonant Raman Response in Anisotropic ReS2.

The strong in-plane anisotropy of rhenium disulfide (ReS 2 ) offers an additional physical parameter that can be tuned for advanced applications such as logic circuits, thin-film polarizers, and polarization-sensitive photodetectors. ReS 2 also presents advantages for optoelectronics, as it is both a direct-gap semiconductor for few-layer thicknesses (unlike MoS 2 or WS 2 ) and stable in air (unlike black phosphorus). Raman spectroscopy is one of the most powerful characterization techniques to nondestructively and sensitively probe the fundamental photophysics of a 2D material. Here, we perform a thorough study of the resonant Raman response of the 18 first-order phonons in ReS 2 at various layer thicknesses and crystal orientations. Remarkably, we discover that, as opposed to a general increase in intensity of all of the Raman modes at excitonic transitions, each of the 18 modes behave differently relative to each other as a function of laser excitation, layer thickness, and orientation in a manner that highlights the importance of electron-phonon coupling in ReS 2 . In addition, we correct an unrecognized error in the calculation of the optical interference enhancement of the Raman signal of transition metal dichalcogenides on SiO 2 /Si substrates that has propagated through various reports. For ReS 2 , this correction is critical to properly assessing the resonant Raman behavior. We also implemented a perturbation approach to calculate frequency-dependent Raman intensities based on first-principles and demonstrate that, despite the neglect of excitonic effects, useful trends in the Raman intensities of monolayer and bulk ReS 2 at different laser energies can be accurately captured. Finally, the phonon dispersion calculated from first-principles is used to address the possible origins of unexplained peaks observed in the Raman spectra, such as infrared-active modes, defects, and second-order processes.

The spiral of distrust: (Non-)cooperation in a repeated trust game is predicted by anger and individual differences in negative reciprocity orientation.

Science.gov (United States)

Harth, Nicole S; Regner, Tobias

2017-12-01

This study investigated state anger and individual differences in negative reciprocity orientation as predictors of individuals' willingness to cooperate with strangers. In order to observe real behaviour, we used a trust game that was played over six periods. In the trust game, a first player (sender) determines how much of a certain endowment she/he wants to share with a second player (trustee), who then can give something back. We varied whether participants received feedback [feedback (yes, no)] about the trustee's behavioural decision (amount sent back). Supporting our hypotheses, the results suggest that feedback compared with no feedback about the trustee's behaviour increased anger. Specifically, information about low back transfers triggered anger and non-cooperation in return. Importantly, participants with a strong negative reciprocity orientation reported higher levels of anger and were less willing to cooperate with the trustee compared with those with low negative reciprocity orientation. Moreover, even when anger was low, individuals with a strong negative reciprocity orientation were less willing to cooperate compared with those with a low negative reciprocity orientation. Thus, negative reciprocity orientation seems to arouse a spiral of distrust. Theoretical and practical implications of these findings are discussed. © 2016 International Union of Psychological Science.

Exploring object-oriented technologies

CERN Multimedia

2000-01-01

Object oriented technologies are the corner stone of modern software development. A piece of software is today conceived, constructed and tested as a set of objects interacting with each other, rather than as a large sequential program. OO is present throughout the whole software life cycle allowing for maintainable code re-use, clean design and manageable complexity. OO is also the seed upon which other technologies are being built and deployed, such as distributed computing, component models, open interoperability, etc.This series of three seminars will provide a pragmatic overview on the main ideas behind OO software development and will explain the inner workings of the most outstanding technologies being built on OO, such as UML, CORBA, Component Models, Agent Oriented Computing, Business Objects, etc.

Rapid Syllable Transitions (ReST) treatment for Childhood Apraxia of Speech: the effect of lower dose-frequency.

Thomas, Donna C; McCabe, Patricia; Ballard, Kirrie J

2014-01-01

This study investigated the effectiveness of twice-weekly Rapid Syllable Transitions (ReST) treatment for Childhood Apraxia of Speech (CAS). ReST is an effective treatment at a frequency of four sessions a week for three consecutive weeks. In this study we used a multiple-baselines across participants design to examine treatment efficacy for four children with CAS, aged four to eight years, who received ReST treatment twice a week for six weeks. The children's ability to acquire new skills, generalize these skills to untreated items and maintain the skills after treatment was examined. All four children improved their production of the target items. Two of the four children generalized the treatment effects to similar untreated pseudo words and all children generalized to untreated real words. During the maintenance phase, all four participants maintained their skills to four months post-treatment, with a stable rather than rising profile. This study shows that ReST treatment delivered twice-weekly results in significant retention of treatment effects to four months post-treatment and generalization to untrained but related speech behaviors. Compared to ReST therapy four times per week, the twice-weekly frequency produces similar treatment gains but no ongoing improvement after the cessation of treatment. This implies that there may be a small but significant benefit of four times weekly therapy compared with twice-weekly ReST therapy. Readers will be able to define dose-frequency, and describe how this relates to overall intervention intensity.

[Empirical study of the market orientation of veterinarians in The Netherlands].

Linked to the theoretical framework of marketing in the veterinary practice, as explained in Schuurmans and Smidts (1) pp. 1-10 and Schuurmans and Smidts (2), an empirical research project has been undertaken. This research gives insight into the extent to which practices base their services on a marketing orientation. By means of telephone inquiries among a sample of 166 veterinarians, this was investigated. The research shows that veterinarians think more in a product-oriented way than in a market-oriented way, and they do not use all the opportunities a marketing orientation could bring to their services. This expresses itself, among others by not using market segmentation, by the inadequate use of the marketing mix elements communication and distribution, and by the fact that the opportunities of the marketing information system are hardly applied. By means of further research in individual practices it might be possible to give concrete advise fit for that practice. Research among the clients of the veterinarians might, beside many other kinds of research, also give valuable insights.

Little is known about the work patterns of re-employed people. We investigated the labour market attachment trajectories of re-employed people and assessed the influence of chronic diseases on these trajectories. The study was based on register data of 18 944 people (aged 18-60 years) who participated in a subsidised re-employment programme in Finland. Latent class growth analysis with zero-inflated Poisson was used to model the labour market attachment trajectories over a 6-year follow-up time. Multinomial logistic regression was used to examine the associations between chronic diseases and labour market attachment trajectories, adjusting for age, gender, educational level, size of town and calendar year in subsidised re-employment programme. We identified four distinct labour market attachment trajectories, namely: strengthening (a relatively stable attachment throughout the follow-up time; 77%), delayed (initial weak attachment increasing later; 6%), leavers (attachment declined with time; 10%) and none-attached (weak attachment throughout the study period; 7%). We found that severe mental problems strongly increased the likelihood of belonging in the leavers (OR 3.61; 95% CI 2.23 to 5.37) and none-attached (OR 3.41; 95% CI 1.91 to 6.10) trajectories, while chronic hypertension was associated with none-attached (OR 1.37; 95% CI 1.06 to 1.77) trajectory. The associations between other chronic diseases (diabetes, heart disease, asthma and arthritics) and labour market attachment trajectories were less evident. Re-employed people appear to follow distinct labour market attachment trajectories over time. Having chronic diseases, especially mental disorders appear to increase the risk for relatively poor labour market attachment. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Wang, L.C.; Tacconi, N.R. de; Chenthamarakshan, C.R.; Rajeshwar, K.; Tao, M.

2007-01-01

Copper (I) oxide (Cu 2 O) films were cathodically electrodeposited on Sn-doped indium oxide substrates. The influence of electrodeposition bath pH on grain orientation and crystallite shape was carefully re-examined using X-ray diffraction and scanning electron microscopy. In addition to the (100) and (111) preferred orientations identified in two previous sets of studies, as the bath pH was varied in the present study from ∼ 7.5 to ∼ 12, a third preferred orientation, (110), was identified in a narrow pH range, ∼ 9.4 to ∼ 9.9. A remarkable shift in the flat-band potential (spanning ∼ 500 mV) was measured in a non-aqueous electrolyte medium for the various Cu 2 O samples obtained from baths of varying pH

Un parfum d’Orient au cœur des villes d’eaux

2012-04-01

Full Text Available Les villes balnéaires et thermales accordent une large place à l’orientalisme. En France, cet orientalisme a tendance à se confondre en grande partie avec l’histoire de la perception de l’architecture islamique. Il participe à la redécouverte du mythe méditerranéen conçu au XIXe siècle ; dans la seconde moitié du siècle, cette représentation se marie avec le goût éclectique. Au cours de la première moitié du XXe siècle, la référence à l’Orient est porteuse d’autres valeurs culturelles, sa présence se fait plus discrète et évolue vers une conception plus épurée et régionaliste, qui se veut intégrée au monde méditerranéen.Seaside and spa resorts had a serious weakness for orientalism. In France, this orientalism can be placed within a larger historical context of how Islamic architecture was perceived. It belongs to the rediscovery and redefinition of the Mediterranean myth during the 19th century. During the second half of this century, it was a style that blended well with eclectic tastes. During the first half of the 20th century, architectural references to the Orient came to bear other cultural values. The orientalism became more discreet and evolved towards a style that was more refined and regionalist, seeing itself as an integral part of the Mediterranean world.

The reEnergize Program helped to build a market for residential and commercial energy evaluations and upgrades. The program provided incentives to encourage participants to save energy, save money, and make their homes and businesses more safe, healthy, and comfortable. As part of the Better Buildings Neighborhood Program (BBNP), the successful investment of this $10 million grant toward market development was the first grant funding collaboration between the cities of Omaha and Lincoln. Through more than three years of work, thousands of participants, contractors, and community members worked together to make the reEnergize Program a demonstration of how to “Build Energy Smart Communities.”

Datafication and empowerment: How the open data movement re-articulates notions of democracy, participation, and journalism

Directory of Open Access Journals (Sweden)

Stefan Baack

2015-07-01

Full Text Available This article shows how activists in the open data movement re-articulate notions of democracy, participation, and journalism by applying practices and values from open source culture to the creation and use of data. Focusing on the Open Knowledge Foundation Germany and drawing from a combination of interviews and content analysis, it argues that this process leads activists to develop new rationalities around datafication that can support the agency of datafied publics. Three modulations of open source are identified: First, by regarding data as a prerequisite for generating knowledge, activists transform the sharing of source code to include the sharing of raw data. Sharing raw data should break the interpretative monopoly of governments and would allow people to make their own interpretation of data about public issues. Second, activists connect this idea to an open and flexible form of representative democracy by applying the open source model of participation to political participation. Third, activists acknowledge that intermediaries are necessary to make raw data accessible to the public. This leads them to an interest in transforming journalism to become an intermediary in this sense. At the same time, they try to act as intermediaries themselves and develop civic technologies to put their ideas into practice. The article concludes with suggesting that the practices and ideas of open data activists are relevant because they illustrate the connection between datafication and open source culture and help to understand how datafication might support the agency of publics and actors outside big government and big business.

Impregnated tungsten cathodes half-coated with Re/W (or Os/W) alloy and Os Re W alloy at right angles were studied to compare the effects of Os Re W alloy coatings on the electron emission and emission mechanisms. Constant surface metal compositions of 32% Os--29% Re--39% W and 35% Os--26% Re--39% W were obtained from the activated surfaces initially coated with 40% Os--40% Re--20% W and 35% Os--45% Re--20% W alloys, respectively. Thermionic emission microscopy measurements showed that the Os Re W alloy-coated surface gives an average effective work function of 0.29, 0.08, and 0.03 eV lower than the uncoated, Re/W and Os/W alloy-coated surfaces. An effective work function of 1.73 eV was obtained from an activated Os Re W alloy surface. Auger studies exhibited a smaller BaO coverage and a higher barium coverage in excess of BaO stoichiometry on the Os Re W alloy-coated surface compared to the uncoated, Re/W and Os/W alloy-coated surfaces

Thanks to a set of semi-structured interviews, its transcription and further analysis of its contents, we have obtained valuable conclusions and reflections which indicate the importance that families give to participation, to the point that they are immerse in the process of transformation in a learning community (CdA. Among the conclusions obtained in the mentioned qualitative study, we have been able to observe the familiar perceptions about participation, the existing obstacles and determinants for it, the relationship between the different members of the educational community, the channels of participation, etc.; a whole range of considerations which provide useful information of political and pedagogical character. These considerations can orientate the implementation of school participation policies and the construction of a cohesive and active educational community.

Children diagnosed with Developmental Coordination Disorder (DCD) present with a variety of impairments in fine and gross motor function, which impact on their activity and participation in a variety of settings. This research aimed to determine if a 10-week group-based Cognitive Orientation to Daily Occupational Performance (CO-OP) intervention improved outcome measures across the impairment, activity and participation levels of the International Classification of Functioning, Disability and Health (ICF) framework. In this quasi-experimental, pre-post-test, 20 male children aged 8-10 years (x9y1m ± 9 m) with a confirmed diagnosis of DCD participated in either the 10 week group intervention based on the CO-OP framework (n = 10) or in a control period of regular activity for 10 weeks (n = 10). Outcome measures relating to impairment (MABC-2, motor overflow assessment), activity (Handwriting Speed Test) and participation [Canadian Occupational Performance Measure, (COPM) and Goal Attainment Scale) were measured at weeks 0 and 10 in the intervention group. Children who participated in the CO-OP intervention displayed improvements in outcome measures for impairment, activity and participation, particularly a reduction in severity of motor overflow. Parent and child performance and satisfaction ratings on the COPM improved from baseline to week 10 and all goals were achieved at or above the expected outcome. No significant changes were reported for the control group in impairment and activity (participation was not measured for this group). The strategies implemented by children in the CO-OP treatment group, targeted towards individualised goal attainment, show that CO-OP, when run in a group environment, can lead to improvements across all levels of the ICF. Development Coordination Disorder is a condition which has significant physical, academic and social impacts on a child and can lead to activity limitations and participation restrictions. Cognitive

Applying a message oriented middleware architecture to the TJ-II remote participation system

Sanchez, E.; Portas, A.; Pereira, A.; Vega, J.

2006-01-01

A message oriented middleware (MOM) has been introduced into the TJ-II data acquisition system to on-line distribute information. Java message service (JMS) has been chosen as the messaging application program interface (API) in order to ensure multiplatform portability. A library of C++ classes providing interface for JMS Java classes has been developed. This allows C++ programs to inter-communicate through JMS. In addition, a set of C wrapper functions has also been developed to provide basic messaging functionalities for C or FORTRAN programs. These functions are used in TJ-II LabView data acquisition applications. Several software applications that take advantage of the MOM architecture have been developed. Firstly, a general-user application allows monitoring of the data acquisition systems. Secondly, a simple application permits the visualization of TJ-II monitor signals with on-line data refreshing. These applications are written in the Java language, thereby ensuring its portability. These software tools provide new functionalities to the TJ-II remote participation system and are equally used in the local environment

We illustrate how Fortran 90 supports object-oriented concepts by example of plasma particle computations on the IBM SP. Our experience shows that Fortran 90 and object-oriented methodology give high performance while providing a bridge from Fortran 77 legacy codes to modern programming principles. All of our object-oriented Fortran 90 codes execute more quickly thatn the equeivalent C++ versions, yet the abstraction modelling capabilities used for scentific programming are comparably powereful.

Ferraro, F Richard; Grossman, Jennifer; Bren, Amy; Hoverson, Allysa

2002-10-01

An experiment was performed that examined the impact of stimulus orientation on performance on the Rey complex figure. A total of 48 undergraduates (24 men, 24 women) were randomly assigned to one of four Rey figure orientation groups (0 degrees, 90 degrees, 180 degrees, and 270 degrees ). Participants followed standard procedures for the Rey figure, initially copying it in whatever orientation group they were assigned to. Next, all participants performed a 15-20 min lexical decision experiment, used as a filler task. Finally, and unbeknownest to them, participants were asked to recall as much of the figure as they could. As expected, results revealed a main effect of Task (F = 83.92, p orientation was not significant, nor did orientation interact with task (Fs .57). The results are important from an applied setting, especially if testing conditions are less than optimal and a fixed stimulus position is not possible (e.g., testing at the bedside).

2009-01-01

We consider the problem of constructing Steiner minimum trees for a metric defined by a polygonal unit circle (corresponding to s = 2 weighted legal orientations in the plane). A linear-time algorithm to enumerate all angle configurations for degree three Steiner points is given. We provide...... a simple proof that the angle configuration for a Steiner point extends to all Steiner points in a full Steiner minimum tree, such that at most six orientations suffice for edges in a full Steiner minimum tree. We show that the concept of canonical forms originally introduced for the uniform orientation...... metric generalises to the fixed orientation metric. Finally, we give an O(s n) time algorithm to compute a Steiner minimum tree for a given full Steiner topology with n terminal leaves....

An Exploratory Study on the Re-finding Behavior on the Web

2010-06-01

Full Text Available It is common for users to relocate information previously found on the web. However, their search behaviors in initial finding and the subsequent re-finding may differ due to the dynamic nature and contextual diversity of the web. This study used experiment, observation, interview, and questionnaires to investigate the characteristics of re-finding behavior and compare users’ performance in finding and re-finding. Though not significantly different, the study participants used more search tools, combined various strategies to obtain contextual clues of finding process, utilized more complex search tactics, and had more interactions with search engines used. Findings also show that participants spent less time in re-finding than in finding, yet the cognitive loading and difficulties increased in re-finding. Participants were satisfied with the results obtained in re-finding, but they also claimed that the search performance would be better if the system offered more functions to support recall of previous search results. Participants’ satisfaction with search performance also varied by task type. Based on the findings, this study recommends that re-finding efficiency may be improved by enhancing recall functionalities in browsers and by using personal information management tools.

ACCOUNTING AND TAX TREATMENT OF THE RE-EVALUATION OF THE TANGIBLE ASSETS

Directory of Open Access Journals (Sweden)

Daniela CRETU

2013-01-01

Full Text Available The methods of patrimonial evaluation are recognised on a large scale by the specialists in the Continental Europe, while the specialists in the North America almost ignore them, they consider as a realistic economic value the one that results from the update of the forecast cash-flows. The Romanian financial school does not mention at present a basic orientation related to the continental or American opinion. In general, it can be found out that the attitude of the Romanian authors, specialised in the accounting domain, is for the patrimonial methods, and those in financial professional domain, is for the financial and stock methods. According to the International Standards for business evaluation, the “asset based approach is the way to estimate the value of a business and /or the participations to it, using methods based on the market value of the individual assets of the business, decreasing its debts”. The entities can proceed to the re-evaluation of the tangible assets that exist at the end of the financial exercise, so that they are presented to their true value in accounting, reflecting the results of this re-evaluation in the financial reports made for that exercise. In this context, the present paper proposes the analysis of the accounting and tax treatmentforeseen by the accounting regulations, according to the European directives, and to the procedures of evaluation and re-evaluation of the tangible assets.

Design of Introspective Circuits for Analysis of Cell-Level Dis-orientation in Self-Assembled Cellular Systems

Directory of Open Access Journals (Sweden)

Nicholas Jesse Macias

2016-02-01

Full Text Available This paper discusses a novel approach to managing complexity in a large self-assembled system, by employing the self-assembling components themselves to address the complexity. Challenges are discussed, including the question of how to deal with elements that are assembled in different orientations from each other, and a solution based on the idea of introspective circuits is described. A methodology for determining a single cell’s orientation from an adjacent cell is given. An algorithm is then described for using such re-oriented edge cells to determine orientation of more-interior cells, thus allowing re-orientation of an entire 2D region of cells. Test procedures are described, and results are presented to show better-than-linear time performance (O(sqrt(n. The significance of this work is discussed, not only in terms of managing arrays of dis-oriented cells, but more importantly as an example of the usefulness of local, distributed self-configuration to create and use introspective circuitry. Finally, future work is discussed, including extension to 3D collections of cells.

The individual-oriented and social-oriented Chinese bicultural self: testing the theory.

Science.gov (United States)

Lu, Luo

2008-06-01

The author proposes a bicultural self theory for contemporary Chinese individuals, encompassing 2 main components: the individual-oriented self and the social-oriented self. The social orientation is rooted in traditional Chinese conceptualization of the self, whereas the individual orientation has evolved and developed under Western influences along with recent societal modernization. The author conducted a series of 5 studies to test the theory and relate the model to important issues in current personality and social psychological research, such as cultural individualism-collectivism, self-construals, motivation, cognition, emotion, and well-being. A total of 977 university students in Taiwan participated. The author found that contrasting self-aspects were differentially associated with the aforementioned constructs, as theoretically predicted. This evidence thus generally supported the bicultural self model.

Predictors of homeless services re-entry within a sample of adults receiving Homelessness Prevention and Rapid Re-Housing Program (HPRP) assistance.

Brown, Molly; Vaclavik, Danielle; Watson, Dennis P; Wilka, Eric

2017-05-01

Local and national evaluations of the federal Homelessness Prevention and Rapid Re-Housing Program (HPRP) have demonstrated a high rate of placement of program participants in permanent housing. However, there is a paucity of research on the long-term outcomes of HPRP, and research on rehousing and prevention interventions for single adults experiencing homelessness is particularly limited. Using Homeless Management Information System data from 2009 to 2015, this study examined risk of return to homeless services among 370 permanently housed and 71 nonpermanently housed single adult HPRP participants in Indianapolis, Indiana. Kaplan-Meier survival curves were conducted to analyze time-to-service re-entry for the full sample, and the homelessness prevention and rapid rehousing participants separately. With an average follow-up of 4.5 years after HPRP exit, 9.5% of the permanently housed HPRP participants and 16.9% of those nonpermanently housed returned to homeless services. By assistance type, 5.4% of permanently housed and 15.8% of nonpermanently housed homelessness prevention recipients re-entered services, and 12.8% of permanently housed and 18.2% of nonpermanently housed rapid rehousing recipients re-entered during the follow-up period. Overall, veterans, individuals receiving rapid rehousing services, and those whose income did not increase during HPRP had significantly greater risk of returning to homeless services. Veterans were at significantly greater risk of re-entry when prevention and rehousing were examined separately. Findings suggest a need for future controlled studies of prevention and rehousing interventions for single adults, aiming to identify unique service needs among veterans and those currently experiencing homelessness in need of rehousing to inform program refinement.

Student goal orientation in learning inquiry skills with modifiable software advisors

Science.gov (United States)

Shimoda, Todd Adrian

A computer support environment (SCI-WISE) for learning and doing inquiry was designed. The system incorporates software advisors that give task completion advice (eg., forming hypotheses), general purpose advice (e.g., brainstorming), or system modification advice. Advisors' knowledge includes concepts, strategies, examples, referrals to other advisors, and criteria for evaluating good products and skills. Students using SCI-WISE can select the advisors' advice type (specific, general, or hints), and when advisors give advice (anytime, alert, or ask). Students can also modify the advisors' knowledge. The system is designed partly on a theoretical framework that assumes giving students higher levels of agency will facilitate higher-level goal orientation (such as knowledge-building) and produce higher levels of competence. In two studies of sixth graders, science students took a pretest of an open-ended inquiry question and a questionnaire that measured their goal orientations. The students worked in pairs on an inquiry project about memory, using one of two versions of SCI-WISE, one modifiable and one not modifiable. After finishing the project, the students took a posttest similar to the pretest, and evaluated the system. The main hypotheses predicted that knowledge-oriented students using the modifiable version would rate the system higher, use it more effectively, and do better on the inquiry posttest than task-oriented students. The results supported many of the hypotheses generated from the theoretical framework. Knowledge-oriented students tended to rate SCI-WISE higher, use more general purpose and system development advisors, and select more general advice and hints than task-oriented students. On the posttest inquiry test, students with higher goal orientations scored higher on average, particularly when paired with another knowledge oriented student. The studies also showed that goal orientation was not correlated with grade point average. Finally, the

Barriers to participation in vocational orientation programmes among prisoners

2015-11-01

Full Text Available This study investigates the barriers to prisoners’ participation in vocational education, as well as the predictors of different types of barriers. Survey data derived from a project in a remand prison in Belgium (N=468 provided the empirical evidence for the analyses. The results indicate that facing situational and informational barriers are most common. Based on the different kinds of barriers, various types of non-participants can be distinguished and multinomial logistic regression analyses are conducted to identify in what way participants of vocational education differ from various types of non-participants. For instance, prisoners with a poor understanding of the Dutch language and those who never/rarely receive visitors participate less in vocational education as they are more likely to be confronted with informational barriers. We conclude this article by discussing paths for future research and implications for policy and practice to anticipate the barriers for those who want to participate in vocational education.

Objective To date there is limited published evidence on the efficacy of tobacco control mass media campaigns in China. This study aimed to evaluate the impact of a mass media campaign “Giving Cigarettes is Giving Harm” (GCGH) on Chinese smokers’ knowledge of smoking-related harms and attitudes toward cigarette gifts. Methods Population-based, representative data were analyzed from a longitudinal cohort of 3,709 adult smokers who participated in the International Tobacco Control China Survey conducted in six Chinese cities before and after the campaign. Logistic regression models were estimated to examine associations between campaign exposure and attitudes about cigarettes as gifts measured post-campaign. Poisson regression models were estimated to assess the effects of campaign exposure on post-campaign knowledge, adjusting for pre-campaign knowledge. Findings Fourteen percent (n=335) of participants recalled the campaign within the cities where the GCGH campaign was implemented. Participants in the intervention cities who recalled the campaign were more likely to disagree that cigarettes are good gifts (71% vs. 58%, pcampaign-targeted knowledge than those who did not recall the campaign (Mean=1.97 vs. 1.62, pcampaign-targeted knowledge were similar in both cities, perhaps due to a secular trend, low campaign recall, or contamination issues. Conclusions These findings suggest that the GCGH campaign increased knowledge of smoking harms, which could promote downstream cessation. Findings provide evidence to support future campaign development to effectively fight the tobacco epidemic in China. PMID:24813427

Radiation safety training courses are indispensable educational programs for radiation workers. We have two kinds of courses, which are held before use of radioisotope (beginner's training course) and held annually (re-training course). The interval between two courses was found to give some effects for radiation worker's recognition and knowledge on radiation safety through the result of examination and questionnaire on the radiation safety after training. The average scores of participants indicated that the short interval (3 months) was better than the long interval (almost one year). Furthermore, the average scores of participants in the 2003 training course were higher than those in the 2002 and 2001 training courses. Several participants were found to lack in the basic radiation safety attitude and knowledge. In order to improve these results, the practical training should be given additionally for workers, who lacked in understanding. (author)

The importance of a servant leader orientation.

Jenkins, Marjorie; Stewart, Alice C

2010-01-01

Ensuring a quality nursing workforce for the future in a time of increasing labor shortage and declining nurse satisfaction is a key challenge to the health care industry. Understanding what impacts job satisfaction is vital to solving the problem of nurse attrition. We suggest that the approach to supporting staff in the care giving role requires additional expectations of managers who supervise inpatient nursing staff. This study empirically tested the impact of nurse managers' servant leadership orientation on nurse job satisfaction. Nurses providing direct bedside patient care within inpatient departments of a five-hospital system were asked to respond to four questionnaires. Seventeen departments participated. There were 346 available nurses across the departments. The average response rate was 73% across all of the units surveyed. Hypotheses were tested using multivariate regression analysis of the nurse-nurse manager dyad. Statistical findings of this study provided evidence that behaviors and attitudes of the nurse manager do impact employee job satisfaction. Departments where staff perceived that managers had higher servant leadership orientation demonstrated significant positive impact on individual employee job satisfaction. Nursing is a unique occupation in that it requires both competence in professional service and compassion in patient caregiving. Hospitals are not factories dealing with inanimate objects or data. The results of this research suggested that the management approach in a health care environment might be enhanced by a more servant-oriented management approach. Specific policy changes that may be implied on the basis of findings of this research include key areas of management selection, management development, and management reward/evaluation.

Screening for Sexual Orientation in Psychiatric Emergency Departments

Currier, Glenn W.

2015-01-01

Full Text Available Introduction: Our goal was to explore whether emergency department (ED patients would disclose their sexual orientation in a research evaluation and to examine demographic and clinical characteristics of patients by self-identified sexual orientation. Methods: Participants (n=177 presented for psychiatric treatment at three urban EDs in New York City, Rochester, NY, and Philadelphia, PA. Participants were interviewed in the context of a larger study of a standardized suicide risk assessment. We assessed participants’ willingness to answer questions regarding sexual orientation along three dimensions: a self-description of sexual orientation, a self-description of sexual attraction, and the gender of any prior sexual partners. Results: No participants (0/177 refused to respond to the categorical question about sexual orientation, 168/177 (94.9% agreed to provide information about prior sexual partners, and 100/109 (91.7% provided information about current sexual attraction toward either gender. Of all 177 participants, 154 (87.0% self-identified as heterosexual, 11 (6.2% as bisexual, 10 (5.6% as gay or lesbian, and 2 (1.1% indicated they were not sure. As compared with heterosexual patients, lesbian, gay and bisexual (LGB patients were significantly younger and more likely to be non-white, but did not differ significantly in terms of education, income, employment, or religious affiliation or participation. Further, LGB participants did not differ from self-identified heterosexual participants for lifetime suicide attempt rate or lifetime history of any mood, substance-related, psychotic spectrum, or other Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV Axis I disorder. Of self-identified heterosexual participants 5.6% (5/89 reported sexual attraction as other than ‘only opposite sex,’ and 10.3% (15/142 of sexually active ‘heterosexual’ participants reported previous same-gender sexual partners.

The favorable nuclear properties of rhenium-188 for therapeutic application are described, together with new methods for the preparation of high yield and stable 188 Re radiopharmaceuticals characterized by the presence of the nitride rhenium core in their final chemical structure. 188 Re is readily available from an 188 W/ 188 Re generator system and a parallelism between the general synthetic procedures applied for the preparation of nitride technetium-99m and rhenium-188 theranostics radiopharmaceuticals is reported. Although some differences between the chemical characteristics of the two metallic nitrido fragments are highlighted, it is apparent that the same general procedures developed for the labelling of biologically active molecules with technetium-99m can be applied to rhenium-188 with minor modification. The availability of these chemical strategies, that allow the obtainment, in very high yield and in physiological condition, of 188 Re radiopharmaceuticals, gives a new attractive prospective to employ this radionuclide for therapeutic applications.

Despite powerful evidence that informal social support contributes to survivors' safety and well-being, mainstream domestic violence (DV) programs have not developed comprehensive models for helping isolated survivors re-engage with these networks. Although many advocates use network-oriented strategies informally, they often do so without resources, funding, or training. This qualitative focus group study explored advocates' use and perceptions of network-oriented strategies. Advocates working in a range of DV programs across one state described the importance of network-oriented work and articulated its five dimensions, including helping survivors build their capacity to form healthy relationships, identify helpful and harmful network members, re-engage with existing networks, develop new relationships, and respond more effectively to network members. © The Author(s) 2015.

The quiescent Microgravity environment can be quite dynamic. Thermocapillary flow about "large" static bubbles on the order of 1mm in diameter was easily observed by following smaller tracer bubbles. The bubble induced flow was seen to disrupt a large dendritic array, effectively distributing free branches about the solid-liquid interface. "Small" dynamic bubbles were observed to travel at fast velocities through the mushy zone with the implication of bringing/detaching/redistributing dendrite arm fragments at the solid-liquid interface. Large and small bubbles effectively re-orient/re-distribute dendrite branches/arms/fragments at the solid liquid interface. Subsequent initiation of controlled directional solidification results in growth of dendrites having random orientations which significantly compromises the desired science.

Task-oriented maximally entangled states

International Nuclear Information System (INIS)

Agrawal, Pankaj; Pradhan, B

2010-01-01

We introduce the notion of a task-oriented maximally entangled state (TMES). This notion depends on the task for which a quantum state is used as the resource. TMESs are the states that can be used to carry out the task maximally. This concept may be more useful than that of a general maximally entangled state in the case of a multipartite system. We illustrate this idea by giving an operational definition of maximally entangled states on the basis of communication tasks of teleportation and superdense coding. We also give examples and a procedure to obtain such TMESs for n-qubit systems.

Human ASPM participates in spindle organisation, spindle orientation and cytokinesis

Woods C Geoffrey

2010-11-01

Full Text Available Abstract Background Mutations in the Abnormal Spindle Microcephaly related gene (ASPM are the commonest cause of autosomal recessive primary microcephaly (MCPH a disorder characterised by a small brain and associated mental retardation. ASPM encodes a mitotic spindle pole associated protein. It is suggested that the MCPH phenotype arises from proliferation defects in neural progenitor cells (NPC. Results We show that ASPM is a microtubule minus end-associated protein that is recruited in a microtubule-dependent manner to the pericentriolar matrix (PCM at the spindle poles during mitosis. ASPM siRNA reduces ASPM protein at the spindle poles in cultured U2OS cells and severely perturbs a number of aspects of mitosis, including the orientation of the mitotic spindle, the main determinant of developmental asymmetrical cell division. The majority of ASPM depleted mitotic cells fail to complete cytokinesis. In MCPH patient fibroblasts we show that a pathogenic ASPM splice site mutation results in the expression of a novel variant protein lacking a tripeptide motif, a minimal alteration that correlates with a dramatic decrease in ASPM spindle pole localisation. Moreover, expression of dominant-negative ASPM C-terminal fragments cause severe spindle assembly defects and cytokinesis failure in cultured cells. Conclusions These observations indicate that ASPM participates in spindle organisation, spindle positioning and cytokinesis in all dividing cells and that the extreme C-terminus of the protein is required for ASPM localisation and function. Our data supports the hypothesis that the MCPH phenotype caused by ASPM mutation is a consequence of mitotic aberrations during neurogenesis. We propose the effects of ASPM mutation are tolerated in somatic cells but have profound consequences for the symmetrical division of NPCs, due to the unusual morphology of these cells. This antagonises the early expansion of the progenitor pool that underpins cortical

An Investigation of the Academic Information Finding and Re-finding Behavior on the Web

Full Text Available Academic researchers often need and re-use relevant information found after a period of time. This preliminary study used various methods, including experiments, interviews, search log analysis, sequential analysis, and observation to investigate characteristics of academic information finding and re-finding behavior. Overall, the participants in this study entered short queries either in finding or re-finding phases. Comparatively speaking, the participants entered greater number of queries, modified more queries, browsed more web pages, and stayed longer on web pages in the finding phase. On the other hand, in the re-finding phase, they utilized personal information management tools to re-find instead of finding again using search engine, such as checking browsing history; moreover, they tend to input less number of queries and stayed shorter on web pages. In short, the participants interacted more with the retrieval system during the finding phase, while they increased the use of personal information management tools in the re-finding phase. As to the contextual clues used in re-finding phase, the participants used less clues from the target itself, instead, they used indirect clues more often, especially location-related information. Based on the results of sequential analysis, the transition states in the re-finding phase was found to be more complex than those in the finding phase. Web information finding and re-finding behavior is an important and novel area of research. The preliminary results would benefit research on Web information re-finding behavior, and provide useful suggestions for developing personal academic information management systems.

Hearld, Larry R; Alexander, Jeffrey A; Mittler, Jessica N

2012-01-01

A touted advantage of multisectoral health care alliances is their ability to coordinate diverse constituencies and pursue community health goals in ways that allow them to make greater progress than each constituency could independently. However, participating organizations may have goals that do not entirely overlap or necessarily align with the alliance's goals, which can weaken or undermine an alliance's efforts. Fostering changes within participating organizations in ways that are consistent with the alliance's goals (i.e., alliance-oriented change) may be one mechanism by which alliances can coordinate diverse activities and improve care in their local communities. We examined whether alliance-oriented change within participating organizations is associated with alliance decision-making and conflict management style, level of participation, perceptions of alliance participation benefits and costs, and awareness of alliance activities within participating organizations. The study used two rounds of survey data collected from organizational participants of 14 alliances participating in the Robert Wood Johnson Foundation's Aligning Forces for Quality program. Alliance participants generally reported low levels of alliance-oriented change within their organizations as a result of the alliance and its activities. However, participants reporting higher levels of internal change in response to alliance activities had more positive perceptions of alliance decision-making style, higher levels of participation in alliance activities, more positive perceptions of alliance participation benefits relative to costs, and greater awareness of alliance activities across multiple levels of their respective organizations. Despite relatively low levels of alliance-oriented change within participating organizations, alliances may still have the means to align the goal orientations of a diverse membership and foster change that may extend the reach of the alliance in the community.

The questionnaire was adapted to Slovene in several steps (two independent translations by experts, reaching agreement, retranslation; modification and its psychometric properties were examined with 1064 participants, aged 18 to 91 years. The participants also rated their satisfaction with life. Confirmatory factor analysis indicated adequate fit of the expected three-factor model. Results showed satisfactory internal consistency of the three scales (alpha coefficients ranged from 0.70 to 0.83 and satisfactory itemtotal correlations. Inter-correlation coefficients suggested low associations between orientation to pleasure and orientation to meaning, while orientation to engagement was moderately related to the other two orientations to happiness. Men and women did not differ statistically significantly in their self-reported orientations to happiness, while age of the participants had a significant, though small negative effect on orientation to pleasure. After accounting for demographic characteristics orientations to pleasure and engagement significantly improved the prediction of subjective life satisfaction. Results also indicate that satisfaction with life was highest in participants relatively high on all three orientations to happiness.

Rhenium Dichalcogenides: Layered Semiconductors with Two Vertical Orientations.

Science.gov (United States)

Hart, Lewis; Dale, Sara; Hoye, Sarah; Webb, James L; Wolverson, Daniel

2016-02-10

The rhenium and technetium diselenides and disulfides are van der Waals layered semiconductors in some respects similar to more well-known transition metal dichalcogenides (TMD) such as molybdenum sulfide. However, their symmetry is lower, consisting only of an inversion center, so that turning a layer upside-down (that is, applying a C2 rotation about an in-plane axis) is not a symmetry operation, but reverses the sign of the angle between the two nonequivalent in-plane crystallographic axes. A given layer thus can be placed on a substrate in two symmetrically nonequivalent (but energetically similar) ways. This has consequences for the exploitation of the anisotropic properties of these materials in TMD heterostructures and is expected to lead to a new source of domain structure in large-area layer growth. We produced few-layer ReS2 and ReSe2 samples with controlled "up" or "down" orientations by micromechanical cleavage and we show how polarized Raman microscopy can be used to distinguish these two orientations, thus establishing Raman as an essential tool for the characterization of large-area layers.

Re-assessment of seismic loads in conjunction with periodic safety review

International Nuclear Information System (INIS)

Jonczyk, Josef

2002-01-01

The objective of this paper is the fundamental consideration of a safeguard-aim-oriented approach for use in the re-assessment of seismic events with regard to the periodic safety review (PSR) of nuclear power plants (NPP). The re-assessment aspects of site-specific design earthquakes (DEQ), specially the procedure for seismic hazard analysis, will not, however, be considered in detail here. The proposed assessment concept clearly presents a general approach for safety assessments. The approach is based on a successive screening review of components that are considered sufficiently earthquake-resistant. In this respect, the principle of maximum practical application of the design documentation has been considered in the re-assessment process. On the other hand, the safeguard-aim-oriented evaluation will also be applied with regard to whether the requirements of the safety regulations are fulfilled with respect to the safety goals. The review in conjunction with PSR does not, however, attempt to perform this under all technical aspects. Moreover, it is possible to make extensive use of experimental knowledge and engineering judgement with regard to the structural capacity behaviour in case of a seismic event. Compared with design procedures, however, this proposed approach differs from the one applied in licensing procedures, in which such assessment freedom will not usually be exhausted. (author)

Disasters are recurring to global problems, which results in homelessness. The affected region had economical, environmental and social problems as well. In relief and reconstruction phases, the need for integrated management appeared in order to use the national sources actively and productively. Especially housing implementations had an important role for future development of the affected region. For accelerating the reconstruction of the region and forming a sustainable community, which maintains itself socially, environmentally and economically over time; energy usage for construction should be kept to a minimum. Past research in Turkey shows that the cost of temporary houses (to be used as the short term shelter) had a ratio of 10-15% of the total expenses of whole construction activity. For saving money and protecting the environment and conserving scarce resources, the affected region must consider the option of temporary houses to meet their short and long-term need during the reconstruction process. After the end of usage, temporary houses should be able to be re-used for the same or new function. This study is a test of re-design and re-use of a temporary housing site; by using recycled materials, minimum energy and voluntary participation so that this site can finally become a permanent housing site.

Anderl, Christine; Steil, Regina; Hahn, Tim; Hitzeroth, Patricia; Reif, Andreas; Windmann, Sabine

2018-06-01

Social anxiety is known to impair interpersonal relationships. These impairments are thought to partly arise from difficulties to engage in affiliative interactions with others, such as sharing favors or reciprocating prosocial acts. Here, we examined whether individuals high compared to low in social anxiety differ in giving towards strangers in an economic game paradigm. One hundred and twenty seven non-clinical participants who had been pre-screened to be either particularly high or low in social anxiety played an incentivized Trust Game to assess trustful and reciprocal giving towards strangers in addition to providing information on real life interpersonal functioning (perceived social support and attachment style). We found that reciprocal, but not trustful giving, was significantly decreased among highly socially anxious individuals. Both social anxiety and reciprocal giving furthermore showed significant associations with self-reported real life interpersonal functioning. Participants played the Trust Game with the strategy method; results need replication with a clinical sample. Individuals high in social anxiety showed reduced reciprocal, but intact trustful giving, pointing to a constraint in responsiveness. The research may contribute to the development of new treatment and prevention programs to reduce the interpersonal impairments in socially anxious individuals. Copyright © 2017 Elsevier Ltd.

Aesthetic Judgement of Orientation in Modern Art

Directory of Open Access Journals (Sweden)

George Mather

2012-01-01

Full Text Available When creating an artwork, the artist makes a decision regarding the orientation at which the work is to be hung based on their aesthetic judgement and the message conveyed by the piece. Is the impact or aesthetic appeal of a work diminished when it is hung at an incorrect orientation? To investigate this question, Experiment 1 asked whether naïve observers can appreciate the correct orientation (as defined by the artist of 40 modern artworks, some of which are entirely abstract. Eighteen participants were shown 40 paintings in a series of trials. Each trial presented all four cardinal orientations on a computer screen, and the participant was asked to select the orientation that was most attractive or meaningful. Results showed that the correct orientation was selected in 48% of trials on average, significantly above the 25% chance level, but well below perfect performance. A second experiment investigated the extent to which the 40 paintings contained recognisable content, which may have mediated orientation judgements. Recognition rates varied from 0% for seven of the paintings to 100% for five paintings. Orientation judgements in Experiment 1 correlated significantly with “meaningful” content judgements in Experiment 2: 42% of the variance in orientation judgements in Experiment 1 was shared with recognition of meaningful content in Experiment 2. For the seven paintings in which no meaningful content at all was detected, 41% of the variance in orientation judgements was shared with variance in a physical measure of image content, Fourier amplitude spectrum slope. For some paintings, orientation judgements were quite consistent, despite a lack of meaningful content. The origin of these orientation judgements remains to be identified.

Preparation and characterization of sintered Mo-Re alloys

Morito, F.

1993-01-01

By the method of powder metallurgy, we have tried to fabricate Mo-Re alloys, which were electron beam weldable. Severe quality control was carried out during the whole fabrication process focused to reducing oxygen contamination. It is inevitable that the starting raw powders of Mo and Re were both high purity with 99.99 mass% up. Moreover, high vacuum sintering was performed before final sintering with high-purity hydrogen gas. As a result, we obtained electron beam weldable Mo-Re alloys, the total oxygen content of which was about 10 mass ppm or less, respectively. Several specimens were melted by electron beam welding (EBW) method. It was found that EBW gives an easy and effective survey to examine the weldability and the quality of the materials. Fracture surfaces examined by AES exhibited very low content of oxygen, carbon and nitrogen or that less than detectability limit. In conclusion, we have succeeded to obtain defect-free welds of sintered Mo-Re alloys. Furthermore it was found that Mo-Re alloys showed excellent potentialities not only in mechanical properties at low temperature but also in the respects of microstructure. (orig.)

Visual communication materials for rural audiences: re-orienting artists and copy-writers.

Chen, P

1989-01-01

An agency of the Indian government cooperated with a United Nations Children Fund to produce posters for the child survival and development program in India. To make the posters and other visual communications more effective a workshop was planned for the artists, visualizers, and copywriters. Previous experience had shown that some visual materials were not always oriented to the local contexts and villages often misinterpreted the messages of these materials. The 12 day workshop was designed to assist artists to better understand the audiences needs. there had been little pretesting of art work for health communication and no consideration of the visual literacy of the audience. The first project in the workshop consisted of artists and copywriters visiting villages to pretest posters presently in circulation. After some reservations they quickly found that the villagers perception of the posters was entirely different than the message being conveyed. By going back and getting the villagers perceptions of common sights related to maternal and child health, the artist could better prepare communication materials. They also collected basic sociological data at each village. New posters were then prepared with the help of inputs from midwives, nurses, and other health care workers. By pretesting these materials again they were able to clarify the messages, and repeated testing showed the posters were more understandable. The participants in the workshop found that visual communications materials demand proper understanding of the subject matter and the audience. Pretesting of materials is necessary before production, and changes should be made to reflect the local culture and surroundings. Posters for rural illiterate audiences should have the minimum written text needed and visual literacy must be assessed.

PurposeTo describe a technique involving REcanalisation and Balloon-Oriented puncture for Re-insertion of dialysis catheter in Nonpatent central veins (REBORN) and to report long-term results.Materials and MethodsThis is a retrospective study of ten subjects in whom dialysis catheters were inserted using the REBORN technique from March 2012 to October 2014 and followed up till April 2016. Data on the duration of catheter usage, complications and reasons for removal were obtained. Seven patients had partially occluded lower internal jugular veins (IJV) recanalised in an antegrade fashion via a more cranial puncture. The balloon was then inflated at usual puncture site with an 18G needle. The collapsed balloon was cannulated with a guide wire, and both balloon and guide wire were advanced together into the superior vena cava. This was followed by tunnelled catheter placement using standard techniques. Two patients had catheters placed in the subclavian vein using a similar antegrade technique, and one patient had catheter placed via the left IJV following retrograde recanalisation from a right femoral puncture.ResultsMean duration of catheter use was 278 days (range 32–503). Three catheters were removed due to matured arteriovenous accesses. Four patients had successful catheter change over the same subcutaneous track due to catheter malfunction. One catheter was removed after 7 months because of sepsis. No complications were reported.ConclusionThe REBORN technique allows for the preservation of central veins for future haemodialysis access, which can be challenging in patients requiring long-term dialysis.

This article explores gift-giving practices using data collected through interviews in Hong Kong. I argue that Chinese culture promotes the familial over the private self and that the attainment of family-oriented goals represents an important measure of self-realization and self-fulfillment. Although each individual also has a private or inner self (chi), it is also subject to the collective will. This idea is in keeping with Confucian ideals that encourage the individual to focus on develop...

Perceived Average Orientation Reflects Effective Gist of the Surface.

Cha, Oakyoon; Chong, Sang Chul

2018-03-01

The human ability to represent ensemble visual information, such as average orientation and size, has been suggested as the foundation of gist perception. To effectively summarize different groups of objects into the gist of a scene, observers should form ensembles separately for different groups, even when objects have similar visual features across groups. We hypothesized that the visual system utilizes perceptual groups characterized by spatial configuration and represents separate ensembles for different groups. Therefore, participants could not integrate ensembles of different perceptual groups on a task basis. We asked participants to determine the average orientation of visual elements comprising a surface with a contour situated inside. Although participants were asked to estimate the average orientation of all the elements, they ignored orientation signals embedded in the contour. This constraint may help the visual system to keep the visual features of occluding objects separate from those of the occluded objects.

Bastida Virgili, B.; Krag, H.; Lips, T.; De Pasquale, E.

2010-09-01

The first ATV was launched on 9th March 2008 and, after a successful mission, the last phase was a controlled destructive re-entry on 29th September 2008, shortly after 13:30 UTC, in which the remains of the ATV and its load fell into the South Pacific Ocean. In order to better understand the re-entry processes, an insitu optical observation campaign was launched to record and analyze the ATV controlled re-entry with several instruments on board of two airplanes and also from the ISS. This observation campaign was successful and triggered several different still-ongoing studies on the extraction and analysis of data to draw conclusions on the adequacy of the re-entry break-up and explosion models used for the safety analysis of the ATV re-entry. This paper addresses the validation process for ESA’s model for re-entry survivability and on-ground risk assessment for explosive re-entry events using the observation data. The underlying rationale is to improve the models for the benefit of planning and execution of future controlled re-entries and in risk calculation in case of uncontrolled ones. The re-entry trajectory of the ATV, the explosive event and the trajectories of the fragments are simulated with the existing ESA tools and the EVOLVE explosion model. Additional software has been developed to simulate airborne sensor field of view(FOV) crossings based on the aircraft trajectories, attitude profile, sensor mounts and FOVs. Sensor performance and object radiation are modeled in order to generate synthetic images for the different sensors in the ISS and the two airplanes. These synthetic images and synthetic videos are compared with the available reentry observations of the ATV. This paper will present the software and techniques to generate synthetic imagery. It will give results of the comparison between the simulated and the real trajectories and fragmentation and explain the subsequent validation process of the ESA re-entry tools and the potential

Sexual orientation and spatial memory.

Cánovas, Ma Rosa; Cimadevilla, José Manuel

2011-11-01

The present study aimed at determining the influence of sexual orientation in human spatial learning and memory. Participants performed the Boxes Room, a virtual reality version of the Holeboard. In Experiment I, a reference memory task, the position of the hidden rewards remained constant during the whole experiment. In Experiment II, a working memory task, the position of rewards changed between blocks. Each block consisted of two trials: One trial for acquisition and another for retrieval. The results of Experiment I showed that heterosexual men performed better than homosexual men and heterosexual women. They found the rewarded boxes faster. Moreover, homosexual participants committed more errors than heterosexuals. Experiment II showed that working memory abilities are the same in groups of different sexual orientation. These results suggest that sexual orientation is related to spatial navigation abilities, but mostly in men, and limited to reference memory, which depends more on the function of the hippocampal system.

Bach, Michael; Schäfer, Kerstin

2016-01-01

Assessment of visual acuity is a well standardized procedure at least for expert opinions and clinical trials. It is often recommended not giving patients feedback on the correctness of their responses. As this viewpoint has not been quantitatively examined so far, we quantitatively assessed possible effects of feedback on visual acuity testing. In 40 normal participants we presented Landolt Cs in 8 orientations using the automated Freiburg Acuity Test (FrACT, feedback was provided in 2 x 4 conditions: (A) no feedback, (B) acoustic signals indicating correctness, (C)visual indication of correct orientation, and (D) a combination of (B) and (C). After each run the participants judged comfort. Main outcome measures were absolute visual acuity (logMAR), its test-retest agreement (limits of agreement) and participants' comfort estimates on a 5-step symmetric Likert scale. Feedback influenced acuity outcome significantly (p = 0.02), but with a tiny effect size: 0.02 logMAR poorer acuity for (D) compared to (A), even weaker effects for (B) and (C). Test-retest agreement was high (limits of agreement: ± 1.0 lines) and did not depend on feedback (p>0.5). The comfort ranking clearly differed, by 2 steps on the Likert scale: the condition (A)-no feedback-was on average "slightly uncomfortable", the other three conditions were "slightly comfortable" (pFeedback affected neither reproducibility nor the acuity outcome to any relevant extent. The participants, however, reported markedly greater comfort with any kind of feedback. We conclude that systematic feedback (as implemented in FrACT) offers nothing but advantages for routine use.

Women's health is an important task in society. The aim of this qualitative study that used a phenomenological approach was to explain women's personal experiences of giving birth in Gonabad city that had positive experiences of giving birth in order to establish quality cares and the related factors of midwifery cares for this physiological phenomenon. The participants were 21 primiparae women who gave a normal and or uncomplicated giving birth in the hospital of Gonabad University of medical sciences. Based on a purposeful approach in-depth interviews were continued to reach data saturation. The data were collected through open and semi-structured interactional in-depth interviews with all the participants. All the interviews were taped, transcribed and then analyzed through a qualitative content analysis method to identify the concepts and themes. Some categories were emerged. A quiet and safe environment was the most urgent need of the most women giving birth. Unnecessary routine interventions that are performed on all women regardless of their needs and should be avoided were considered such as: "absolute rest, establishing vein, frequent vaginal examinations, fasting and early Amniotomy". All the women wanted to take part actively in their giving birth, because they believed it could affect their giving birth. We hope that the women's experiences of giving birth will be a pleasant and enjoyable experience for all the mothers giving birth.

Re-passivation Potential of Alloy 22 in Chloride plus Nitrate Solutions using the Potentiodynamic-Galvano-static-Potentiostatic Method

International Nuclear Information System (INIS)

Evans, Kenneth J.; Rebak, Raul B.

2007-01-01

In general, the susceptibility of Alloy 22 to suffer crevice corrosion is measured using the Cyclic Potentiodynamic Polarization (CPP) technique. This is a fast technique that gives rather accurate and reproducible values of re-passivation potential (ER1) in most cases. In the fringes of susceptibility, when the environment is not highly aggressive, the values of re-passivation potential using the CPP technique may not be highly reproducible, especially because the technique is fast. To circumvent this, the re-passivation potential of Alloy 22 was measured using a slower method that combines Potentiodynamic-Galvano-static-Potentiostatic steps (called here the Tsujikawa-Hisamatsu Electrochemical or THE method). The THE method applies the charge to the specimen in a more controlled way, which may give more reproducible re-passivation potential values, especially when the environment is not aggressive. The values of re-passivation potential of Alloy 22 in sodium chloride plus potassium nitrate solutions were measured using the THE and CPP methods. Results show that both methods yield similar values of re-passivation potential, especially under aggressive conditions. (authors)

Heather Zimmerman and Jennifer Weible's (Cult Stud Sci Educ, 2016) use of place-based pedagogy in high school science education honors their participants' lived experiences and the rural communities from which they come. They raise an unresolved tension in their findings: Why did the youth in their study, who clearly learned a lot about the local watershed, not feel empowered or knowledgeable enough to propose collective, action-oriented strategies to address the poor quality of the water? We use this tension as a focus point of our response, drawing on one author's (Huffling's) biography and David Gruenewald's (Educ Res 32:3-12, 2003. doi: 10.3102/0013189X032004003) critical pedagogy of place to re-imagine the curriculum that Zimmerman and Weible describe. We provide strategies that align with Gruenewald's (2003) constructs of decolonization and reinhabitation that could promote youths' collective empowerment.

Sociality Mental Modes Modulate the Processing of Advice-Giving: An Event-Related Potentials Study

Full Text Available People have different motivations to get along with others in different sociality mental modes (i.e., communal mode and market mode, which might affect social decision-making. The present study examined how these two types of sociality mental modes affect the processing of advice-giving using the event-related potentials (ERPs. After primed with the communal mode and market mode, participants were instructed to decide whether or not give an advice (profitable or damnous to a stranger without any feedback. The behavioral results showed that participants preferred to give the profitable advice to the stranger more slowly compared with the damnous advice, but this difference was only observed in the market mode condition. The ERP results indicated that participants demonstrated more negative N1 amplitude for the damnous advice compared with the profitable advice, and larger P300 was elicited in the market mode relative to both the communal mode and the control group. More importantly, participants in the market mode demonstrated larger P300 for the profitable advice than the damnous advice, whereas this difference was not observed at the communal mode and the control group. These findings are consistent with the dual-process system during decision-making and suggest that market mode may lead to deliberate calculation for costs and benefits when giving the profitable advice to others.

Orientation Transfer in Vernier and Stereoacuity Training.

Science.gov (United States)

Snell, Nathaniel; Kattner, Florian; Rokers, Bas; Green, C Shawn

2015-01-01

Human performance on various visual tasks can be improved substantially via training. However, the enhancements are frequently specific to relatively low-level stimulus dimensions. While such specificity has often been thought to be indicative of a low-level neural locus of learning, recent research suggests that these same effects can be accounted for by changes in higher-level areas--in particular in the way higher-level areas read out information from lower-level areas in the service of highly practiced decisions. Here we contrast the degree of orientation transfer seen after training on two different tasks--vernier acuity and stereoacuity. Importantly, while the decision rule that could improve vernier acuity (i.e. a discriminant in the image plane) would not be transferable across orientations, the simplest rule that could be learned to solve the stereoacuity task (i.e. a discriminant in the depth plane) would be insensitive to changes in orientation. Thus, given a read-out hypothesis, more substantial transfer would be expected as a result of stereoacuity than vernier acuity training. To test this prediction, participants were trained (7500 total trials) on either a stereoacuity (N = 9) or vernier acuity (N = 7) task with the stimuli in either a vertical or horizontal configuration (balanced across participants). Following training, transfer to the untrained orientation was assessed. As predicted, evidence for relatively orientation specific learning was observed in vernier trained participants, while no evidence of specificity was observed in stereo trained participants. These results build upon the emerging view that perceptual learning (even very specific learning effects) may reflect changes in inferences made by high-level areas, rather than necessarily fully reflecting changes in the receptive field properties of low-level areas.

The study of molybdenites through the 187Re-187Os chronometer

Luck, J.M.; Allegre, C.J.

1982-01-01

We determined the Re and Os concentrations in 11 molybdenites of various ages (30-2700 m.y.) and from various areas. No 'common' osmium has been detected and Os was found to be purely radiogenic. Therefore, by comparing the concentrations, we were able to determine 187 Re- 187 Os ages. For most samples these ages are in good agreement with those measured in surrounding rocks and probably correspond to the age of mineralization. However, two or three Re-Os ages seem unreliable being probably related to some rhenium leaching through later metamorphic and/or hydrothermal events: this shows that the petrographic characteristics of ores and the type of crystallization of MoS 2 are important in choosing samples suitable for dating. Re and Os determinations combined with careful petrographic investigations may give important clues on the genesis and evolution of molybdenum ores. (orig.)

Full Text Available Now days lesbian, gay, bisexual, and transgender are abbreviated as LGBT is the most popular word and being sensible in the world, especially in Indonesia. Based on human right principles, any person in the world including in Indonesia is free to express their gender identity and sexual orientation, even the same sex marriage, freely from unlawful discrimination and violations (Office of Personnel Management, 2015; Yogyakarta Principles, 2006. However, because of the culture and religion differences backgrounds, Indonesians have given this issue various responses. In general, Indonesian public opinion on LGBT are split into two different groups, one minority group is proponent to present of LGBT and any things related to it, and another majority groups are opponent. Objective of this editorial is to discuss how sexual orientation develop from prenatal until emerging of clinical manifestation in adulthood, by no mean to support either group. Otherwise, to give more insight about how male and female get their appropriate sexual orientations and why some of them get inappropriate sexual orientations.

Turbulence modeling for flows around convex features giving rapid eddy distortion

International Nuclear Information System (INIS)

Tucker, P.G.; Liu, Y.

2007-01-01

Reynolds averaged Navier-Stokes model performances in the stagnation and wake regions for turbulent flows with relatively large Lagrangian length scales (generally larger than the scale of geometrical features) approaching small cylinders (both square and circular) is explored. The effective cylinder (or wire) diameter based Reynolds number, Re W ≤ 2.5 x 10 3 . The following turbulence models are considered: a mixing-length; standard Spalart and Allmaras (SA) and streamline curvature (and rotation) corrected SA (SARC); Secundov's ν t -92; Secundov et al.'s two equation ν t -L; Wolfshtein's k-l model; the Explicit Algebraic Stress Model (EASM) of Abid et al.; the cubic model of Craft et al.; various linear k-ε models including those with wall distance based damping functions; Menter SST, k-ω and Spalding's LVEL model. The use of differential equation distance functions (Poisson and Hamilton-Jacobi equation based) for palliative turbulence modeling purposes is explored. The performance of SA with these distance functions is also considered in the sharp convex geometry region of an airfoil trailing edge. For the cylinder, with Re W ∼ 2.5 x 10 3 the mixing length and k-l models give strong turbulence production in the wake region. However, in agreement with eddy viscosity estimates, the LVEL and Secundov ν t -92 models show relatively little cylinder influence on turbulence. On the other hand, two equation models (as does the one equation SA) suggest the cylinder gives a strong turbulence deficit in the wake region. Also, for SA, an order or magnitude cylinder diameter decrease from Re W = 2500 to 250 surprisingly strengthens the cylinder's disruptive influence. Importantly, results for Re W W = 250 i.e. no matter how small the cylinder/wire its influence does not, as it should, vanish. Similar tests for the Launder-Sharma k-ε, Menter SST and k-ω show, in accordance with physical reality, the cylinder's influence diminishing albeit slowly with size. Results

Rare-Earth Calcium Oxyborate Piezoelectric Crystals ReCa4O(BO33: Growth and Piezoelectric Characterizations

Fapeng Yu

2014-07-01

Full Text Available Rare-earth calcium oxyborate crystals, ReCa4O(BO33 (ReCOB, Re = Er, Y, Gd, Sm, Nd, Pr, and La , are potential piezoelectric materials for ultrahigh temperature sensor applications, due to their high electrical resistivity at elevated temperature, high piezoelectric sensitivity and temperature stability. In this paper, different techniques for ReCOB single-crystal growth are introduced, including the Bridgman and Czochralski pulling methods. Crystal orientations and the relationships between the crystallographic and physical axes of the monoclinic ReCOB crystals are discussed. The procedures for dielectric, elastic, electromechanical and piezoelectric property characterization, taking advantage of the impedance method, are presented. In addition, the maximum piezoelectric coefficients for different piezoelectric vibration modes are explored, and the optimized crystal cuts free of piezoelectric cross-talk are obtained by rotation calculations.

Fabrication of thermoelectric Bi-based cobaltites with large magnetic anisotropy (Δχ = χ c - χ ab ) and relatively low resistivity using a crystallochemical process is reported. Doping of various rare earth (RE) ions into the Ca site in [(Bi 0.5 Pb 0.5 ) 2 Ca 2 O 4 ] y CoO 2 [(Bi, Pb)Ca222] enhanced Δχ comparable to that of [Ca 2 CoO 3-δ ] 0.62 CoO 2 . Tailoring of the Sr-doping level in Dy-doped (Bi, Pb)Ca222 enabled the resistivity to be reduced without decreasing Δχ. The magnetically c-axis-oriented (Sr, Dy)-doped (Bi, Pb)Ca222 bulk exhibited improved thermoelectric performance compared with the Sr-free RE-doped BiCa222 and a-axis grain-oriented [(Bi 0.5 Pb 0.5 ) 2 Sr 2 O 4 ] ∼0.55 CoO 2

Fast and accurate edge orientation processing during object manipulation

Flanagan, J Randall; Johansson, Roland S

Quickly and accurately extracting information about a touched object’s orientation is a critical aspect of dexterous object manipulation. However, the speed and acuity of tactile edge orientation processing with respect to the fingertips as reported in previous perceptual studies appear inadequate in these respects. Here we directly establish the tactile system’s capacity to process edge-orientation information during dexterous manipulation. Participants extracted tactile information about edge orientation very quickly, using it within 200 ms of first touching the object. Participants were also strikingly accurate. With edges spanning the entire fingertip, edge-orientation resolution was better than 3° in our object manipulation task, which is several times better than reported in previous perceptual studies. Performance remained impressive even with edges as short as 2 mm, consistent with our ability to precisely manipulate very small objects. Taken together, our results radically redefine the spatial processing capacity of the tactile system. PMID:29611804

188 Re from 188 W- 188 Re generator, is recently introduced in therapeutic nuclear medicine and made it possible to use whenever needed. We synthesized MAG 2 GABA-Biocytin (MGB), labelled with 188 Re for pretargeted radioimmunotherapy and evaluated biological behavior of 188 Re-MGB. N-hydroxysuccinimidyl ester of S-benzoyl mercaptoacetyldiglycine (NHS-MAG 2 ) was synthesized first, reacted with aminobutyric acid(GABA) to give MAG 2 GABA and then converted to NHS-MAG 2 GABA and conjugated to biocytin to give the MGB. To label MGB with 188 Re (50mA), ag, 200ml 1M tartrate pH7, 200 l stannous (10mg/mL) and 180MBq perrhenate were mixed and heated for 30min at 100 deg. C. The reactant was purified with C 18 Sep-Pak. HPLC analysis of the 188 Re-MGB performed on reverse phase C 18 column with a gradient. To see the stability, 188 Re-MGB was added to serum at 37 deg. C. Binding capacity of 188 Re-MGB to avidin or streptavidin was determined by size exclusion HPLC system. Biodistribution was studied in ICR normal mice(n=4/group), from 5min to 120min. In Raji cells tumour bearing nude mice(n=3), biotinylated Lym-1(40MEG) injection after 48 h, streptavidin(50MEG) was injected. 24 h later, 188 Re-MGB(0.5MEG) was injected, and biodistribution was observed 2 h later. 188 Re-MGB was obtained with labelling yield 98%. Stability in serum was maintained over 70% until 3 h. Binding capacity of 188 Re-MGB to streptavidin was greater than avidin. In normal mice, 188 Re-MGB was excreted via hepatobiliary pathway,%ID/g of GI tract was 52.1 at 120min. In Raji cells tumour bearing nude mice, liver and colon were higher than those of normal mouse. Tumour uptake at 120min was 0.05%ID/g. 188 Re-MGB was effectively labelled and retained binding activity with streptavidin. 188 Re-MGB may have a role in pretargeted radioimmunotherapy. (author)

The relationship between the social network and physical health has been studied extensively and it has consistently been shown that individuals live longer, have fewer physical symptoms of illness, and have lower blood pressure when they are a member of a social network than when they are isolated. Much of the research has focused on the benefits of receiving social support from the network and the effects of giving to others within the network have been neglected. The goal of the present research was to systematically investigate the relationship between giving and ambulatory blood pressure. Systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate were recorded every 30 min during the day and every 60 min at night during a 24-h period. Linear mixed models analyses revealed that lower systolic and diastolic blood pressure and mean arterial pressure were related to giving social support. Furthermore, correlational analyses revealed that participants with a higher tendency to give social support reported greater received social support, greater self-efficacy, greater self-esteem, less depression, and less stress than participants with a lower tendency to give social support to others. Structural equation modeling was also used to test a proposed model that giving and receiving social support represent separate pathways predicting blood pressure and health. From this study, it appears that giving social support may represent a unique construct from receiving social support and may exert a unique effect on health.

An Ada-based preprocessor language for concurrent object oriented programming

International Nuclear Information System (INIS)

Almulla, M.; Al-Haddad, M.; Loeper, H.

2001-01-01

In this paper, implementation issues of concurrent-objected programming using Ada 95 are addressed. Ada is not a pure object-oriented language; in order to make it so, a uniform template for structuring object classes is proposed. The template constitutes a basis for an Ada-based preprocessor language that handles concurrent object-oriented programming. The preprocessor accepts Ada-like object-oriented programs (object classes, subclasses and main program) as input and produces Ada 95 concurrent object-oriented program units as output. The preprocessor language has the advantage of adding a new component to the class specification called the protocol, which specifies the order for requesting methods f an object. The preprocessor also touches on the extensibility of object classes issue. It supports defining class hierarchies by inheritance and aggregation. In addition, the preprocessor language supports the re-use of Ada packages, which are not necessarily written according to the object-oriented approach. The paper also investigates the definition of circular dependent object classes and proposes a solution for introducing a collection of classes. (author)

2017-12-01

Although much later compared to other industries including aerospace, automobile, oil and gas etc., digital technology development has been cresting towards an exponential curve in the construction industry. Technological diversity and abundance change the game from “what you can” to “what you want”. Society is changing at an unprecedented rate. Consequently adaptability will be crucial. This research paper explores the integration of digital adaptive technologies that transform the construction industry from the mass production to that of a possible client-oriented mass customization. The focus on the design, construction and performance stages of a building project, currently undergoing major overhaul faces a paradigm shift globally that will impact and compel attention for the next three decades with viable solutions such as Building Information Modelling (BIM) to manage massive data cum information. Customization maximizes clients’ participation during the design process thereby achieving greater effective value and higher satisfaction. A study between customized and standardized examples will investigate how adaptive customization will shift the design paradigm from cost to value centric. This action research will explore different aspects of emerging innovative systems already in place pushing the edge of frontiers, and transforming the building industry landscape whether micro or giga, to compliment new technologies to create an unprecedented exhilaration of freshness over the mundane, routine and mediocrity. Three identified fundamental aspects that are instrumental to Client-oriented Building Mass Customization (CoBMC) are design option visualization, parametric product information and n-dimensional modelling. The study concluded that a paradigm shift is therefore inevitable for every stakeholder including clients who will need to re-examine their roles, capabilities, and competencies in preparation towards challenging future.

Extending our previous work 'Fields on the Poincare group and quantum description of orientable objects' (Gitman and Shelepin 2009 Eur. Phys. J. C 61 111-39), we consider here a classification of orientable relativistic quantum objects in 3+1 dimensions. In such a classification, one uses a maximal set of ten commuting operators (generators of left and right transformations) in the space of functions on the Poincare group. In addition to the usual six quantum numbers related to external symmetries (given by left generators), there appear additional quantum numbers related to internal symmetries (given by right generators). Spectra of internal and external symmetry operators are interrelated, which, however, does not contradict the Coleman-Mandula no-go theorem. We believe that the proposed approach can be useful for the description of elementary spinning particles considered as orientable objects. In particular, it gives a group-theoretical interpretation of some facts of the existing phenomenological classification of spinning particles.

Full Text Available We consider reflection principle for classical solutions of the homogeneous real Monge–Ampère equation. We show that both the odd and the even reflected functions satisfy the Monge–Ampère equation if the second-order partial derivatives have continuous limits on the reflection boundary. In addition to sufficient conditions, we give some necessary conditions. Before stating the main results, we present elementary formulas for the reflected functions and study their differentiability properties across the reflection boundary. As an important special case, we finally consider extension of polynomials satisfying the homogeneous Monge–Ampère equation.

Peer support is an emerging form of person-driven active health care. Chronic conditions such as Ménière's disease (a disorder of the inner ear) need continuing rehabilitation and support that is beyond the scope of routine clinical medical practice. Hence, peer-support programs can be helpful in supplementing some of the rehabilitation aspects. The aim of this study was to design a computerized data collection system for the peer support of Menière's disease that is capable in profiling the subject for diagnosis and in assisting with problem solving. The expert program comprises several data entries focusing on symptoms, activity limitations, participation restrictions, quality of life, attitude and personality trait, and an evaluation of disease-specific impact. Data was collected from 740 members of the Finnish Ménière's Federation and utilized in the construction and evaluation of the program. The program verifies the diagnosis of a person by using an expert system, and the inference engine selects 50 cases with matched symptom severity by using a nearest neighbor algorithm. These cases are then used as a reference group to compare with the person's attitude, sense of coherence, and anxiety. The program provides feedback for the person and uses this information to guide the person through the problem-solving process. This computer-based peer-support program is the first example of an advanced computer-oriented approach using artificial intelligence, both in the profiling of the disease and in profiling the person's complaints for hearing loss, tinnitus, and vertigo. ©Jyrki Rasku, Ilmari Pyykkö, Hilla Levo, Erna Kentala, Vinaya Manchaiah.

Strong oriented chromatic number of planar graphs without short cycles

2008-01-01

Full Text Available Let M be an additive abelian group. A strong oriented coloringof an oriented graph G is a mapping φ from V(G to M such that (1 φ(u ≠ φ(v whenever uv is an arc in G and (2 φ(v - φ(u ≠ -(φ(t - φ(z whenever uv and zt are two arcs in G. We say that G has a M-strong-oriented coloring. The strong oriented chromatic number of an oriented graph, denoted by χ s (G, is the minimal order of a group M, such that G has M-strong-oriented coloring. This notion was introduced by Nešetřil and Raspaud. In this paper, we pose the following problem: Let i ≥ 4 be an integer. Let G be an oriented planar graph without cycles of lengths 4 to i. Which is the strong oriented chromatic number of G ? Our aim is to determine the impact of triangles on the strong oriented coloring. We give some hints of answers to this problem by proving that: (1 the strong oriented chromatic number of any oriented planar graph without cycles of lengths 4 to 12 is at most 7, and (2 the strong oriented chromatic number of any oriented planar graph without cycles of length 4 or 6 is at most 19.

Software SCMS re-engineering for a objected oriented language (JAVA) for use in construction of segmented phantoms

International Nuclear Information System (INIS)

Possani, Rafael Guedes

2012-01-01

Recent treatment planning systems depend strongly on CT images and the tendency is that the internal dosimetry procedures in nuclear medicine therapy be also based on images, such as magnetic resonance imaging (MRI) and computed tomography (CT), to extract anatomical and histological information, as well as, functional imaging or activities map as PET and SPECT. This information associated with a radiation transport simulation software is used to estimate internal dose in patients undergoing treatment in nuclear medicine. This work aims to re-engineer the software SCMS, which is an interface software between the Monte Carlo code MCNP, and the medical images, that carry information from the patient in treatment. In other words, the necessary information contained in the images are interpreted and presented in a specific format to the Monte Carlo MCNP code to perform the simulation of radiation transport. Therefore, the user does not need to understand the complex process of inputting data on MCNP, as the SCMS is responsible for automatically constructing anatomical data from the patient, as well as the radioactive source data. The SCMS was originally developed in Fortran-77. In this work it was rewritten in an object-oriented language (JAVA). New features and data options have also been incorporated into the software. Thus, the new software has a number of improvements, such as intuitive GUI and a menu for the selection of the energy spectra correspondent to a specific radioisotope stored in a XML data bank. The new version also supports new materials and the user can specify an image region of interest for the calculation of absorbed dose. (author)

Full Text Available Sex role orientation, i.e. a person’s masculinity or femininity, influences cognitive and emotional performance, like biological sex. While it is now widely accepted that sex differences are modulated by the hormonal status of female participants (menstrual cycle, hormonal contraceptive use, the question, whether hormonal status and sex hormones also modulate participants sex role orientation has hardly been addressed previously. The present study assessed sex role orientation and hormonal status as well as sex hormone levels in three samples of participants from two different cultures (Northern American, Middle European. Menstrual cycle phase did not affect participant’s masculinity or femininity, but had a significant impact on reference group. While women in their follicular phase (low levels of female sex hormones determined their masculinity and femininity in reference to men, women in their luteal phase (high levels of female sex hormones determined their masculinity and femininity in reference to women. Hormonal contraceptive users rated themselves as significantly more feminine and less masculine than naturally cycling women. Furthermore, the impact of biological sex on the factorial structure of sex role orientation as well as the relationship of estrogen to masculinity/femininity was modulated by culture. We conclude that culture and sex hormones interactively affect sex role orientation and hormonal status of participants should be controlled for when assessing masculinity and/or femininity.

2001-06-01

The present study compared redo coronary artery bypass grafting (Re-OPCAB) techniques with conventional redo coronary artery bypass grafting (Re-CABG) with particular focus on myocardial damage and clinical outcome parameters. Redo OPCAB (Re-OPCAB) was performed on 20 consecutive patients (15 males, mean age 63.2 +/- 9.3 years) using either the anterolateral approach for minimally invasive direct coronary artery bypass (n = 4) or the Octopus technique with regular sternotomy (n = 16). The Re-CABG group consisted of 20 consecutive patients (18 males, mean age 67.1 +/- 6.6 years). Groups did not differ in the number of atherosclerotic risk factors, or left ventricular, renal or liver function. Duration of surgery, number of bypass grafts and amount of transfused red blood cells did not differ significantly between both groups. Requirement of epinephrine (mg/h) within the first 24 h was lower in the Re-OPCAB group (Re-OPCAB: 0.14 +/- 0.22 vs. CABG: 0.88 +/- 0.97; p<0.01). In addition, CKMB levels at 24 h after operation were lower in the Re-OPCAB group (Re-OPCAB: 10.0 +/- 10.1 vs. Re-CABG: 38.7 +/- 28.1 U/l, p<0.001). There were no acute myocardial infarctions or deaths in the perioperative period. In the CABG group, there was a longer time period to extubation (hours) (Re-OPCAB: 9.8 +/- 3.9 vs. Re-CABG: 28.7 +/- 25.5; p<0.001), and the length of ICU stay was significantly prolonged (OPCAB: 1.3 +/- 0.5 versus Re-CABG: 4.4 +/- 8.7; p<0.001). The graft patency rate at follow-up was 95% in the Re-OPCAB group. Re-OPCAB results in decreased cardiac specific enzyme release, reduced requirement of inotropes and comparable clinical outcome in the early postoperative period. It is an appropriate alternative to conventional Re-CABG in selected patients awaiting reoperation for myocardial revascularization. Larger prospective and randomized trials are required to select the appropriate patient who benefits most from one or the other treatment regime.

We propose here the use of cathodic electrodeposition as tool to fabricate implant coatings consisting in nano/micro single crystals of hydroxyapatite (HA), preferentially orientated along the c-axis. Coating characterization is the base of this work, where we discuss the mechanisms related to the deposition of oriented hydroxyapatite thin films. It is shown that when deposited on titanium alloys, the HA coating is constituted by two distinct regions with different morphologies: at a distance of few microns from the substrate, large HA single crystals are oriented along the c-axis and appear to grow up from a base material, consisting in an amorphous HA. This organized system has a great importance for cell investigation once the variables involved in the cell/surface interaction are reduced. The use of such systems could give a new insight on the effect of particular HA orientation on the osteoblast cells.

Participation in social forestry re-examined: a case-study from Bangladesh.

Science.gov (United States)

Khan, N A; Begum, S A

1997-08-01

Bangladesh has enthusiastically launched social forestry projects that make grandiose promises of seeking local community involvement and participation in the management of forest resources. This study examines the functioning of the Chandra Agroforestry Research and Demonstration Project to evaluate the actual extent and nature of popular participation it entails. After discussing the project and its locale, the methodology of the study is described as an analysis of qualitative and quantitative data collected in the period February-August 1994. The theoretical framework was based on a modified version of Zaman's framework that uses prevalence and opportunity as the indicators of participation. Analysis of prevalence indicators reveals that professional foresters make all major decisions for the project without consulting the farmers involved. The government also has sole responsibility for monitoring and evaluating the project, and the farmers are skeptical that the government will allow them to profit from the benefits arising from the project. Analysis of opportunity indicators shows that the project is not decentralized, cooperative and collaborative linkages have not been made, project flexibility has been sacrificed to bureaucracy, and the incentives promised to the farmers have not materialized. It is concluded that the participation of local residents in the Chandra project has been insignificant but that the project has succeeded in reducing 1) the historical distrust and conflict between forestry officials and local farmers, 2) encroachment on government lands, and 3) the rate of deforestation. In addition, the project has given participating farmers a sense of security.

The aim of this study was to evaluate the knowledge of sports participants regarding emergency management of dental trauma and the awareness about mouthguards. A specific questionnaire regarding knowledge, experiences and behaviours after dental trauma and the use of mouthguard was distributed to 359 sports participants up to 18 years of age. The sports involved were basketball, swimming, volleyball, soccer, tennis, badminton, handball, athleticism, golf, gymnastics, water polo and karate. The questions were focused on personal experience, awareness of first aid and dental emergency procedures and knowledge about mouthguards. The results showed that 10.9% had experienced a kind of dental trauma, and 12.5% would look for a dentist for treatment in emergency. 34.5% would re-implant the avulsed tooth, 33.4% would maintain the avulsed tooth in handkerchief and 25.3% would maintain it in saline solution. 41.1% were aware of the possibility of oral injuries during sports practice, and 55.4% knew about mouthguards, but only 11.2% of the participants reported to use them. There was a statistically significant difference between the experienced participants (>5 years) and less-experienced group (aesthetic' was significantly high in experienced participants. The less-experienced participants significantly stated that they had never heard about mouthguards before. Our results showed a lack of knowledge of sports participants about management and prevention of traumatic dental injuries. Educational programs should be organized to give information about emergency treatment and promote the use of mouthguards to sport participants. © 2014 John Wiley & Sons A/S.

Indigenous concepts of orientation of South Sulawesian sailors

Directory of Open Access Journals (Sweden)

Horst H. Liebner

2005-01-01

Full Text Available This article presents some initial results of ongoing research on concepts of orientation of some maritime-orientated ethnic groups of South Sulawesi. I will not discuss the technicalities of indigenous navigation, but focus on the underlying concepts and categories of spatial orientation. I approach this through an analysis of the expressions and terms used by contemporary ‘traditional’ sailors and navigators to indicate a destination or direction. After outlining the problem and giving examples of spatial terminology used by South Sulawesian fishermen, sailors, and inter-island traders, in the second section I explain in detail the directional terms employed by the sailor-traders of Bira as an example of the complexity and sophistication of these patterns. The third and fourth sections place the discussion in the wider context of migration and settlement of insular Southeast Asia.

Re-irradiation of the human spinal cord

Sminia, P.; Oldenburger, F.; Hulshof, M.C.C.M.; Slotman, B.J.; Schneider, J.J.

2002-01-01

Purpose: Experimental animal data give evidence of long-term recovery of the spinal cord after irradiation. By extrapolation of these data, re-irradiation regimes were designed for eight patients who required palliative radiotherapy. As a consequence of reirradiation, their spinal cords were exposed to cumulative doses exceeding the tolerance dose. Radiobiological and clinical data are presented. Patients and method: Eight patients were re-irradiated on the cervical (n=1), thoracic (n=5) and lumbar (n=2) spinal cord. The time interval between the initial and re-treatment ranged from 4 months to 12.7 years (median: 2.5 years). (Re-)treatment schemes were designed and analyzed on basis of the biologically effective dose (BED) according to the linear-quadratic model. The repair capacity (α/β ratio) for the cervico-thoracic and lumbar spinal cord was assumed to be 2 Gy and 4 Gy, with a BED tolerance of 100 Gy and 84 Gy, respectively. Results: The cumulative irradiation dose applied to the spinal cord varied between 125 and 172% of the BED tolerance . During follow-up, ranging from 33 days to >4.5 years (median: 370 days) none of the patients developed neurological complications. Seven patients died from tumor progression, and one patient is still alive. Conclusion: Long-term recovery of the spinal cord from radiation injury, which has been demonstrated in rodents and primates, may also occur in humans. (orig.) [de

Sexual orientation and gender: stereotypes and beyond.

Science.gov (United States)

Sandfort, Theo G M

2005-12-01

In this essay, I explore empirical research about the relationship between sexual orientation and gender. Both concepts have multiple meanings, which hinder an unequivocal understanding of the relationship between the two concepts. One of the first studies assumed to establish a relationship between male homosexuality and femininity was conducted by L. M. Terman and C. C. Miles (1936). The study actually gives a much more complicated picture of the relationship. Terman and Miles actually found two groups of homosexual men with, respectively, extremely high masculinity and extremely high femininity scores. Subsequently, various other studies examined the relationship between sexual orientation and gender, introducing the concept of androgyNY. While these studies were executed, major changes took place in the homosexual world, which have been characterized as the masculinization of culture. It is unclear how these changes relate to the masculine and feminine properties of the men involved. Various suggestions are made for further research on the relation between gender and sexual orientation.

Shroder, Deborah Y; Lippert, Lisa G; Goldman, Yale E

2016-11-22

Subdomains of macromolecules often undergo large orientation changes during their catalytic cycles that are essential for their activity. Tracking these rearrangements in real time opens a powerful window into the link between protein structure and functional output. Site-specific labeling of individual molecules with polarized optical probes and measurement of their spatial orientation can give insight into the crucial conformational changes, dynamics, and fluctuations of macromolecules. Here we describe the range of single molecule optical technologies that can extract orientation information from these probes, review the relevant types of probes and labeling techniques, and highlight the advantages and disadvantages of these technologies for addressing specific inquiries.

2008-07-01

Full Text Available As it is known, the management adaptability to the changes taking place in the environment where it is acting represents a key factor for survival and development of an organization. As a reaction to the external signals, the internal change may be superficial when it affects only the development of activity in different sectors, or might be profound, when it changes the main processes and rules of the business and even the philosophy of the company’s existence. Speaking about structural changes, one of the most common approaches of the modern management is the re-design of the business architecture. The new architectural models such as Service Oriented Architecture (SOA, presented in this paper, come with important advantages, but their implementation is not always very easy. This paper tries to present some of the most common encountered contextual characteristics which are able to start the implementation of Service Oriented Architecture, some advantages of this concept as well as some practical approaches of implementing.

Goal-Oriented Ethics: Framing the Goal-Setting Concretely

Directory of Open Access Journals (Sweden)

Mathew Illathuparampil

2017-10-01

Full Text Available Joseph Selling, professor emeritus from KU Leuven, Belgium, recently made a significant contribution towards ethical methodology. It is in fact a continuation of the in-house conversations that have been in vogue about methods in moral reasoning since Vatican II in the discipline called theological ethics. What is specific about Selling’s attempt is that he re-orients or reframes the evaluation of the moral event to consider human intentionality or motivation before considering human behavior or human acts. He convincingly establishes his method by a meticulous reading of Thomas Aquinas. This paper is a response to the goal-oriented ethics that he has posited. As illustrated below, this paper evaluates the goal-oriented approach as solid and sufficient. While fully endorsing this approach, this paper argues that the process of ethical goal-setting is to be framed concretely. In a concrete historical context, so that a goal-oriented approach fully serves its purpose, this paper proposes that it is to be reinforced by four supportive pillars, which are in fact assumed by Selling in his work. They are openness to human sciences, conversation among various narratives, positing a theological frame for ethical reasoning, and recourse to non-discursive reasoning.

Traditional gift-giving (TGG) is an important element of familial obligations among Pacific families. Migration from Pacific homelands to New Zealand and other countries has had an impact on participation in TGG., Many anecdotal accounts have suggested that TGG diminishes when Pacific persons marry outside their ethnic groups. While TGG is an indicator of social cohesion TGG can have direct influence on disposable income. The practice of TGG impacts on health as Income and social cohesion are key determinants of health. Thus TGG Health and social cohesion are closely interrelated and interdependent. The data for this paper is taken from a longitudinal cohort study of 1,398 Pacific children and their families in South Auckland, New Zealand. The study sought participants' responses to questions pertaining to the amounts gifted, the frequency of giving, recipients of the gifting and their reasons for participating and not participating in TGG. The assumption explored in this paper is that as Pacific peoples move outside their social sphere and become more acculturated with other ethnic groups, TGG was more likely to diminish rather than increase. This paper addresses the TGG participation rates among Pacific peoples in inter-ethnic relationships and intra-ethnic relationships. It argues that couples in an intra-ethnic intimate relationship are more likely to participate in traditional gift-giving than those who are in inter-ethnic intimate relationships. While this is true for most PI inter ethnic relationships the level of participation increases further with inter-ethnic intimate relationships among Tongans and Samoans who are also the largest participators of all ethnic groups in traditional gift-giving.

2006-01-01

Medical logic modules are a procedural representation for sharing task-specific knowledge for decision support systems. Based on the premise that clinicians may perceive object-oriented expressions as easier to read than procedural rules in Arden Syntax-based medical logic modules, we developed a method for improving the readability of medical logic modules. Two approaches were applied: exploiting the concept-oriented features of the Medical Entities Dictionary and building an executable Java program to replace Arden Syntax procedural expressions. The usability evaluation showed that 66% of participants successfully mapped all Arden Syntax rules to Java methods. These findings suggest that these approaches can play an essential role in the creation of human readable medical logic modules and can potentially increase the number of clinical experts who are able to participate in the creation of medical logic modules. Although our approaches are broadly applicable, we specifically discuss the relevance to concept-oriented nursing terminologies and automated processing of task-specific nursing knowledge.

2000-01-01

A successful one year long, field scale demonstration of the use of groundwater re-infection at Fernald was recently completed bringing DOE one step closer to achieving an accelerated site remediation (DOE 2000). The demonstration marks the end of a several year effort to evaluate whether: re-injection could be conducted efficiently at Fernald, and if the approved aquifer remedy at Fernald would benefit by incorporating re-infection. Evaluation of re-injection technology involved not only technical considerations, but also participation and cooperation of regulators and stakeholders. The demonstration was considered to be unique in that it was integrated into the design of the current approved aquifer remedy and utilized the existing remediation infrastructure. Information collected during the demonstration indicated that re-injection wells could be operated efficiently at Fernald and that the current approved groundwater remedy should be modified to include the use of re-injection

Tórtora, Giuliana; Ares, Gastón

2018-04-01

Time orientation can influence health-related behaviors, including food consumption. The aim of the present work was to study the influence of time orientation on food choice, using cookie labels as case study. A choice-conjoint task was designed using labels differing in type of cookie (chocolate chips vs. granola), front-of-pack nutrition information (nutritional warnings vs. Facts Up Front system) and nutritional claim (no claim vs. "0% cholesterol. 0% trans fat"). An online study was conducted, in which 155 participants evaluated 8 pairs of cookie labels and selected the one they would buy if they were in the supermarket. Then, they were asked to complete a consideration of future consequences scale (CFC) adapted to eating habits, as well as a questionnaire about socio-demographic characteristics. Time orientation influenced participants' choices of cookies labels; particularly the importance attached to type of cookie. Participants with greater consideration of future consequences preferred the granola cookies, associated with health, while those who prioritized immediate consequences preferred chocolate chip cookies. In addition, nutritional warnings discouraged choice regardless of participants' time orientation. Results from the present work provide additional evidence of the influence of time preferences on food choices and suggest that strategies to stimulate and generate a more future-oriented perspective on eating habits could contribute to more healthful food choices.

Reframing the goals of care conversation: "we're in a different place".

Back, Anthony L; Trinidad, Susan B; Hopley, Elizabeth K; Edwards, Kelly A

2014-09-01

Existing recommendations for communicating with patients with metastatic cancer about redefining goals of care when anticancer treatment is unlikely to provide benefit are based on limited evidence. This study was designed to elicit patient and family views on commonly used communication practices. Participants were 37 patients with metastatic gastrointestinal cancer and 20 bereaved family members who listened to audiorecordings of oncology fellows instructed to discuss a transition in goals of care with a standardized patient for whom evidence-based palliative chemotherapy was no longer effective. During semistructured qualitative interviews, participants commented on the audiorecordings to give feedback on what they liked or disliked about the oncologist's communication. These comments were transcribed and analyzed. Three preferred communication practices were identified from participants' comments. The first practice involves a necessary disruption of the patient's expectations about "trying another chemo" ("We're in a different place"). The second practice is offering actionable responses to the disruption ("Here's what we can do now"). The third practice is to find a new place that acknowledges death is closer yet still allows for "living forward" ("Use your inner wisdom"). This study of patient and family feedback indicates that patients and families perceive a conversation about goals of care to require disruption of an existing routine, followed by a process of searching and then reconfiguration, rather than a logical decision process. These findings suggest that assessing quality from patient perspectives must take into account a period of disruption and chaos.

Re-Vitalizing Worthiness: A theory of overcoming suicidality

Directory of Open Access Journals (Sweden)

Evelyn Gordon, RPN, Reg. Fam. Ther. & Sup. (FTAI, MSc, Ph.D.

2011-06-01

Full Text Available Rates of suicide and suicidality have risen in many countries in recent years and in Ireland this trend has been particularly evident among young men (NOSP, 2005, focusing attention on how best to respond to this group. Although mental health professionals have been identified as a key group to respond to the suicidal person, it has been suggested that they are ill-prepared for working in this area (Maltsberger & Goldblatt, 1996; Ting et al., 2006; Cutcliffe & Stevenson, 2007. This study aimed to address these issues by developing a theoretical understanding of suicidality among young men to inform professional practice. Using Classic Grounded Theory (Glaser & Strauss, 1967, in-depth one-to-one interviews were conducted with 17 young men who had been suicidal and had been in contact with the mental health services. The substantive theory that emerged, re-vitalizing worthiness in overcoming suicidality, describes the psychosocial process that young men go through to resolve their main concern, which centres on their painful pull between life and death. Overcoming suicidality involves moving from a death orientation to a life orientation while incorporating the inevitability of death into their new sense of being. This transition entails identity re-configuration whereby young men emerge as individuals of value who are deserving of life. The process is influenced significantly by personal insights and interpersonal interactions that influence their suicide trajectories and life pathways. The theory contributes to the fields of suicidology and mental health by providing a theoretical understanding of overcoming suicidality and identifying professional and social practices that facilitate and impede this process.

The Functional Role of Resignation Orientation on Goal Engagement, Self-Esteem, Life Satisfaction, and Depression.

Asano, Kenichi; Ishimura, Ikuo; Kodama, Masahiro

2014-11-06

Several studies in Europe and North America have highlighted the importance of resignation or giving up. Research has shown that resignation is as important as goal attainment. Hence, this study examines, using path analysis, the effect of resignation orientation on goal disengagement and reengagement. Furthermore, this study attempts to clarify the implication of resignation orientation for elements of mental well-being. Questionnaires were completed by 261 Japanese college students. Results showed that proactive resignation orientation promotes reestablishment of alternative goals while negative resignation orientation encourages disengagement of the unattainable goals. The findings help explain the functional role of resignation orientation and can inform the development of treatment for resignation-related depression.

To identify and describe the impact of a coping and physical activity-oriented rehabilitation intervention on alcoholic liver disease patients after hepatic encephalopathy in terms of their interaction with professionals and relatives. Patients who have experienced alcohol-induced hepatic encephalopathy have reduced quality of life, multiple complications, and social problems, and rehabilitation opportunities for these patients are limited. A grounded theory study and an evaluation study of a controlled intervention study. Semi-structured interviews were conducted with 10 alcoholic liver disease patients who were diagnosed with hepatic encephalopathy and participated in a coping and physical activity-oriented rehabilitation intervention. Richard S. Lazarus's theory of stress and coping inspired the interview guide. The significance of a coping and physical activity-oriented rehabilitation intervention on alcoholic liver disease patients' ability to cope with problems after surviving alcohol-induced hepatic encephalopathy in terms of their interaction with professionals and relatives was characterised by the core category 'regain control over the diseased body'. This is subdivided into three separate categories: 'the experience of being physically strong', 'togetherness' and 'self-control', and they impact each other and are mutually interdependent. Alcoholic liver disease patients described the strength of the rehabilitation as regaining control over the diseased body. Professionals and relatives of patients with alcoholic liver disease may need to focus on strengthening and preserving patients' control of their diseased body by facilitating the experience of togetherness, self-control and physical strength when interacting with and supporting patients with alcoholic liver disease. A coping and physical activity-oriented rehabilitation intervention may help alcoholic liver disease patients to regain control over their diseased body and give patients the experience

Prior research has found higher rates of mental health problems among sexual minority individuals. We examine treatment-seeking for depression, as well as its relationship with sexual orientation, in a large, multilingual, international sample. Participants in an automated, quintilingual internet-based depression screening tool were screened for depression, and completed several background measures, including sexual orientation (with an option to decline to state) and past and current depression treatment seeking. 3695 participants screened positive for current or past depression and responded to the sexual orientation question. Those who declined to state their sexual orientation were far less likely to seek any treatment than individuals endorsing any orientation; they were especially unlikely to seek psychotherapy. Individuals identifying as bisexual sought both psychotherapy and alternative treatments at a higher rate than other groups. An interaction was observed between sexual orientation and gender, such that lesbian women were especially likely to have used psychotherapy. Other variables that emerged as significant predictors of treatment-seeking for depression included age and participant's language. Limitations include possible misinterpretation of translated terms due to regional differences, and possible limits to generalizability due to this study being conducted on the internet. Our results suggest that individuals who decline to state their sexual orientation may be more likely to forgo effective treatments for depression. Further studies of depression service utilization should focus on developing treatment modalities that could better engage sexual minority individuals, especially those who are reluctant to disclose their orientation.

Consistently Showing Your Best Side? Intra-individual Consistency in #Selfie Pose Orientation

Science.gov (United States)

Lindell, Annukka K.

2017-01-01

Painted and photographic portraits of others show an asymmetric bias: people favor their left cheek. Both experimental and database studies confirm that the left cheek bias extends to selfies. To date all such selfie studies have been cross-sectional; whether individual selfie-takers tend to consistently favor the same pose orientation, or switch between multiple poses, remains to be determined. The present study thus examined intra-individual consistency in selfie pose orientations. Two hundred selfie-taking participants (100 male and 100 female) were identified by searching #selfie on Instagram. The most recent 10 single-subject selfies for the each of the participants were selected and coded for type of selfie (normal; mirror) and pose orientation (left, midline, right), resulting in a sample of 2000 selfies. Results indicated that selfie-takers do tend to consistently adopt a preferred pose orientation (α = 0.72), with more participants showing an overall left cheek bias (41%) than would be expected by chance (overall right cheek bias = 31.5%; overall midline bias = 19.5%; no overall bias = 8%). Logistic regression modellng, controlling for the repeated measure of participant identity, indicated that sex did not affect pose orientation. However, selfie type proved a significant predictor when comparing left and right cheek poses, with a stronger left cheek bias for mirror than normal selfies. Overall, these novel findings indicate that selfie-takers show intra-individual consistency in pose orientation, and in addition, replicate the previously reported left cheek bias for selfies and other types of portrait, confirming that the left cheek bias also presents within individuals’ selfie corpora.

2008-01-01

We examined whether or not increasing visual perceptual load or visual working memory (WM) load would affect the exogenous orienting of visuo-spatial attention, in order to assess whether or not exogenous orienting is genuinely automatic. In Experiment 1, we manipulated visual perceptual load by means of a central morphing shape that in some trials morphed into a particular target shape (a rectangle) that participants had to detect. In Experiment 2, the possibility that the presentation of any changing stimulus at fixation would eliminate exogenous orienting was ruled out, by presenting two alternating letters at fixation. In Experiment 3, we manipulated visual WM load by means of arrays consisting of three (low-load) or five (high-load) randomly located coloured squares. The participants had to remember these items in order to judge whether a cued square had been presented in the same or different colour at the end of each trial. In all the experiments, exogenous visuo-spatial attentional orienting was measured by means of an orthogonal spatial cuing task, in which the participants had to discriminate the elevation (up vs. down) of a visual target previously cued by a spatially nonpredictive visual cue. The results showed that increasing the perceptual load of the task eliminated the exogenous orienting of visuo-spatial attention. By contrast, increasing the WM load had no effect on spatial orienting. These results are discussed in terms of the light that they shed on claims regarding the automaticity of visuo-spatial exogenous orienting.

On line nuclear orientation: opportunity and challenge

International Nuclear Information System (INIS)

Stone, N.J.

1985-01-01

The development of the on-line nuclear orientation (OLNO) technique is reviewed. The present potential of the technique is discussed in the light of the attainable temperatures, the use of ion implantation and the required isotope flux. Limitations associated with spin-lattice relaxation are considered in some detail and a survey of accessible nuclei is presented. An outline comparison is given between OLNO and other methods for producing orientation of nuclei, for measuring nuclear spins and static moments and for the study of level structure and transition probabilities. The conclusion is drawn that the method in its present form has extensive potential over a wide range of nuclei. Future prospects for in-beam polarisation giving access to nuclei of shorter half lives are referred to briefly. (Auth.)

Abiola, T; Udofia, O; Abdullahi, A T

2014-01-01

Attitude and orientation of doctors to the doctor-patient relationship has a direct influence on delivery of high quality health- care. No study to the knowledge of these researchers has so far examined the practice orientation of doctors in Nigeria to this phenomenon. The aims of this study were to determine the orientation of Kano doctors to the practice of doctor-patient relationship and physicians' related-factors. Participants were doctors working in four major hospitals (i.e., two federal-owned and two state-owned) servicing Kano State and its environs. The Patient-Practitioner Orientation Scale (PPOS) and a socio-demographic questionnaire were completed by the 214 participants. The PPOS has 18 items and measures three parameters of a total score and two dimension of "sharing" and "caring". The mean age of participants was 31.72 years (standard deviation = 0.87), with 22% being females, 40.7% have been practicing for ≥ 6 years and about two-third working in federal-owned health institution. The Cronbach's alpha of total PPOS scores was 0.733 and that of two sub-scale scores of "sharing" and "caring" were 0.659 and 0.546 respectively. Most of the doctors' orientation (92.5%) was towards doctor-centered (i.e., paternalistic) care, majority (75.2%) upheld the view of not sharing much information and control with patients, and showing little interest in psychosocial concerns of patients (i.e., 'caring'=93.0%). Respondents' characteristics that were significantly associated with high doctor 'caring' relationship orientation were being ≥ 30-year-old and practicing for ≥ 6 years. Working in State-owned hospitals was also significantly associated with high doctor "sharing" orientation. This paper demonstrated why patient-centered medical interviewing should be given top priority in medical training in Nigeria, and particularly for federal health institutions saddled with production of new doctors and further training for practicing doctors.

Care-giving as a Canadian-Vietnamese tradition: 'it's like eating, you just do it'.

Donovan, Rhonda; Williams, Allison M

2015-01-01

The objective of this study was to examine how Vietnamese family caregivers (FCGs) perceive, manage and experience end-of-life care-giving for seriously ill family members. Using an instrumental case study design, this longitudinal qualitative research employed the use of cultural brokers/language interpreters to help ensure that the research was conducted in a culturally-appropriate manner. Participants (n = 18) discussed their experiences of care-giving within the context of a traditional cultural framework, which was found to influence their motivations and approaches to care-giving, as well as their propensities towards the use of various supports and services. The study was carried out in southern Ontario, Canada, and participants were providing home-based care-giving in the community. Data were collected throughout 2010 and 2011. The ways in which care-giving was perceived and expressed are reflected in three themes: (i) Natural: identity and care work; (ii) Intentional: whole-person care; and (iii) Intensive: standards, struggle and the context of care. This research confirms the need for culturally-appropriate services and supports while illustrating that Vietnamese FCGs not only value, but are also likely to use healthcare and social services if they are language-accessible, built on trust and demonstrate respect for their values as individuals, regardless of culture. © 2014 The Authors.

Rhenium Re

International Nuclear Information System (INIS)

Busev, A.I.; Tiptsova, V.G.; Ivanov, V.M.

1978-01-01

The basic methods for determining rhenium in various objects are presented. The gravimetric determination of rhenium is based on a quantitative precipitation of ReO 4 - ions with tetraphenylarsonium chloride. The determination is not hindered by tungstates and molybdates. The potentiometric determination of rhenium in alloys (>=0.5% Re) is based on perrhenate ion reduction to Re(4) with the titrated solution of the Cr(2) salt. Re(7) is titrated in a hot sulfuric acid solution in the presence of KJ. The relative error of the method is 1 to 3%. The photometric determination of rhenium is performed by the rhodamide method in molybdenum-and tungsten-containing alloys and catalytically, in rocks, after it has been separated in the form of sulfide. The extraction-photometric determination of rhenium is carried out with the aid of methyl violet (analysis of a stock with a high content of Mo, W, Ta, Nb, Ti ahd Zr) and thio-oxine (the determination of Re is hindered by Au, Pt, Pd, Ru, Os, Rh, Ir). Also described are methods for differential-spectrophotometric determination of Re with the aid of thiocarbamide, as well as with the aid of dimethylglyoxime in the presence of SnCl 2 in an acid medium when Re is determined in its alloys with niobium and hafnium. It takes 2 hours to analyze the Hf-Re alloy and 3 hours to analyze the Nb-Re alloy, the standard deviation being 0.005 at 30-50% Re and 0.027 to 0.019 at 10-50% Re

Feature-based attentional modulation of orientation perception in somatosensation

Directory of Open Access Journals (Sweden)

Meike Annika Schweisfurth

2014-07-01

Full Text Available In a reaction time study of human tactile orientation detection the effects of spatial attention and feature-based attention were investigated. Subjects had to give speeded responses to target orientations (parallel and orthogonal to the finger axis in a random stream of oblique tactile distractor orientations presented to their index and ring fingers. Before each block of trials, subjects received a tactile cue at one finger. By manipulating the validity of this cue with respect to its location and orientation (feature, we provided an incentive to subjects to attend spatially to the cued location and only there to the cued orientation. Subjects showed quicker responses to parallel compared to orthogonal targets, pointing to an orientation anisotropy in sensory processing. Also, faster reaction times were observed in location-matched trials, i.e. when targets appeared on the cued finger, representing a perceptual benefit of spatial attention. Most importantly, reaction times were shorter to orientations matching the cue, both at the cued and at the uncued location, documenting a global enhancement of tactile sensation by feature-based attention. This is the first report of a perceptual benefit of feature-based attention outside the spatial focus of attention in somatosensory perception. The similarity to effects of feature-based attention in visual perception supports the notion of matching attentional mechanisms across sensory domains.

A severe capacity limit in the consolidation of orientation information into visual short-term memory.

Becker, Mark W; Miller, James R; Liu, Taosheng

2013-04-01

Previous research has suggested that two color patches can be consolidated into visual short-term memory (VSTM) via an unlimited parallel process. Here we examined whether the same unlimited-capacity parallel process occurs for two oriented grating patches. Participants viewed two gratings that were presented briefly and masked. In blocks of trials, the gratings were presented either simultaneously or sequentially. In Experiments 1 and 2, the presentation of the stimuli was followed by a location cue that indicated the grating on which to base one's response. In Experiment 1, participants responded whether the target grating was oriented clockwise or counterclockwise with respect to vertical. In Experiment 2, participants indicated whether the target grating was oriented along one of the cardinal directions (vertical or horizontal) or was obliquely oriented. Finally, in Experiment 3, the location cue was replaced with a third grating that appeared at fixation, and participants indicated whether either of the two test gratings matched this probe. Despite the fact that these responses required fairly coarse coding of the orientation information, across all methods of responding we found superior performance for sequential over simultaneous presentations. These findings suggest that the consolidation of oriented gratings into VSTM is severely limited in capacity and differs from the consolidation of color information.

Development of a generic seed crystal for the fabrication of large grain (RE)-Ba-Cu-O bulk superconductors

International Nuclear Information System (INIS)

Shi, Y; Babu, N Hari; Cardwell, D A

2005-01-01

The critical current density, J c , irreversibility field, B irr , and magnetic field trapping ability of (LRE)-Ba-Cu-O bulk superconductors, where LRE is a light rare earth element such as Nd, Sm, Eu and Gd, are generally superior to those of the more common melt-processed Y-Ba-Cu-O (YBCO). The lack of availability of a suitable seed crystal to grow large, single grain (LRE)-Ba-Cu-O superconductors with controlled orientation, however, has hindered severely the development of these materials for engineering applications over the past ten years. In this communication we report for the first time the development of a generic seed crystal that can be used to fabricate any rare earth (RE) based (RE)-Ba-Cu-O ((RE)BCO) superconductor in the form of a large single grain with controlled orientation. The new seed crystal will potentially enable large grain (LRE)-Ba-Cu-O bulk superconductors to be fabricated routinely, as is the case for YBCO. This will enable the field trapping and current-carrying characteristics of these materials to be explored in more detail than has been possible to date. (rapid communication)

Pierre Bourdieu and Jacques Rancière on art/aesthetics and politics: the origins of disagreement, 1963-1985.

Science.gov (United States)

Robbins, Derek

2015-12-01

Rancière published two substantial criticisms of the work of Bourdieu in the early 1980s. It is possible that these were provoked by his sense that he needed to oppose what he considered to be the sociological reduction of aesthetic taste offered by Bourdieu in Distinction (Bourdieu 1986 [1979]) at precisely the moment when he (Rancière) was beginning to articulate his commitment to the potential of aesthetic expression as a mode of political resistance. Except in so far as it draws upon some of the retrospective reflections offered by Rancière in his introductions to the re-issues of his early texts, this paper examines the parallel development of the thinking of the two men up to the mid-1980s--but not beyond. The discussion is situated socio-historically and, by definition, does not seek to offer comparatively any transhistorical assessment of the values of the positions adopted by the two men. I argue that Rancière misrepresented the character of Bourdieu's sociological work by failing to recognize the underlying phenomenological orientation of his thinking. Bourdieu suppressed this orientation in the 1960s but, after the May events of 1968, it enabled him to expose the extent to which the practices of both science and art operate within constructed 'fields' in strategic distinction from popular primary experience. The challenge is to introduce an ongoing dialogue between primary and constructed cultures rather than to suppose that either social science or art possesses intrinsic autonomy. © London School of Economics and Political Science 2015.

Chemical effects of nuclear transformations in mixed crystals. 7. Chemical effects of the 35Cl(n,γ)36Cl nuclear reaction in K2ReCl6-K2ReBr6 mixed crystals

The solid-state reactions occurring during the moderation of recoiling 36 Cl, produced by the (n,γ) reaction, have been studied in K 2 ReCl 6 -K 2 ReBr 6 mixed crystals. The main reaction products are Re 36 ClCl 5 2- , Re 36 ClBr 5 2- , and 36 Cl - , but the more intimately mixed species Re 36 ClCl/sub n/Br/sub 5-n/ 2- (n = 1, 2, 3, 4) are found in significant amounts. The production of the different recoil-labeled species can be explained by elementary impact models: 6% of the recoils do not leave their original lattice site (primary retetion); between 6% and 23%, dependent upon the mixed-crystal composition, appear as interstitials; 31 to 48% give rise to direct displacement reactions of one halide ligand; and 40% produce larger disruption by substitution of at least two halide ligands. The results have been compared with Roessler's 38 Cl recoil experiments

Peer attitudes towards adolescent participants in male- and female-oriented sports.

Alley, Thomas R; Hicks, Catherine M

2005-01-01

This study examined gender stereotypes in peer ratings of femininity and masculinity for adolescent participants in three sports. Following a preliminary study of gender stereotyping of several sports, high school students rated unfamiliar cohorts each of whom was described in a single paragraph as either a male or female dedicated participant in one of three sports. A total of 12 different descriptive paragraphs were used in a 2 (race) x 2 (sex) x 3 (sport) design. Each of these paragraphs, although short, ascribed a variety of traits that could be seen by raters as the independent variables: name (initials only), age, race, gender, hours of practice per week, number of competitions/performances per year, sport, and self-confidence. For this reason, raters were highly unlikely to surmise that sex and sport were the primary independent variables in the study. As predicted, there was a consistent decrease in rated femininity and increase in masculinity for both male and female adolescent targets as they switched from participating in a "feminine" (ballet) to a neutral (tennis) to a "masculine" (karate) sport. These results suggest that sex stereotypes for certain sports may influence who elects to participate and how participants are viewed by others.

Monetary rewards influence retrieval orientations.

Reward anticipation during learning is known to support memory formation, but its role in retrieval processes is so far unclear. Retrieval orientations, as a reflection of controlled retrieval processing, are one aspect of retrieval that might be modulated by reward. These processes can be measured using the event-related potentials (ERPs) elicited by retrieval cues from tasks with different retrieval requirements, such as via changes in the class of targeted memory information. To determine whether retrieval orientations of this kind are modulated by reward during learning, we investigated the effects of high and low reward expectancy on the ERP correlates of retrieval orientation in two separate experiments. The reward manipulation at study in Experiment 1 was associated with later memory performance, whereas in Experiment 2, reward was directly linked to accuracy in the study task. In both studies, the participants encoded mixed lists of pictures and words preceded by high- or low-reward cues. After 24 h, they performed a recognition memory exclusion task, with words as the test items. In addition to a previously reported material-specific effect of retrieval orientation, a frontally distributed, reward-associated retrieval orientation effect was found in both experiments. These findings suggest that reward motivation during learning leads to the adoption of a reward-associated retrieval orientation to support the retrieval of highly motivational information. Thus, ERP retrieval orientation effects not only reflect retrieval processes related to the sought-for materials, but also relate to the reward conditions with which items were combined during encoding.

Sexual orientation disparities in adolescent depressive symptoms are well established, but reasons for these disparities are less well understood. We modeled sexual orientation disparities in depressive symptoms from late adolescence into young adulthood and evaluated family satisfaction, peer support, cyberbullying victimization, and unmet medical needs as potential mediators. Data were from waves 2 to 6 of the NEXT Generation Health Study ( n = 2396), a population-based cohort of US adolescents. We used latent growth models to examine sexual orientation disparities in depressive symptoms in participants aged 17 to 21 years, conduct mediation analyses, and examine sex differences. Relative to heterosexual adolescents, sexual minority adolescents (those who are attracted to the same or both sexes or are questioning; 6.3% of the weighted sample) consistently reported higher depressive symptoms from 11th grade to 3 years after high school. Mediation analyses indicated that sexual minority adolescents reported lower family satisfaction, greater cyberbullying victimization, and increased likelihood of unmet medical needs, all of which were associated with higher depressive symptoms. The mediating role of cyberbullying victimization was more pronounced among male than female participants. Sexual minority adolescents reported higher depressive symptoms than heterosexual adolescents from late adolescence into young adulthood. Collectively, low family satisfaction, cyberbullying victimization, and unmet medical needs accounted for >45% of differences by sexual orientation. Future clinical research is needed to determine if interventions targeting these psychosocial and health care-related factors would reduce sexual orientation disparities in depressive symptoms and the optimal timing of such interventions.

this study explored the views of three cohorts of final year midwifery students, regarding their confidence in giving advice to women on contraception and sexual health in the postnatal period. The project also investigated knowledge of contraception using a factual quiz, based on clinical scenarios regarding contraception and sexual health in the postpartum period. a mixed method design using qualitative data from focus groups, and mixed qualitative and quantitative data from a paper based questionnaire was used. the project was carried out in one higher educational institution in England. findings demonstrate that expressed confidence varies according to contraceptive method, with most confidence being reported when advising on the male condom. The findings of the factual quiz indicate that students applied theoretical knowledge poorly in a practically oriented context. These findings also indicated that most students limited advice to general advice. the paper concludes that midwifery students need more practically oriented education in contraception and sexual health, and that the role of mentors is very important in helping students feel confident when giving advice in this area.

1982-09-01

This investigation examined the effects of orienting task-controlled processing on the text recall of younger (18 to 32 years), middle-aged (39 to 51 years), and older (59 to 76 years) adults. The participants were presented with a 500-word narrative text. Three groups performed orienting tasks (syntactic, stylistic, advice) within an incidental memory paradigm. A fourth group was asked for intentional recall. Analysis indicated a significant age by orienting task interaction. Younger adults recalled more propositions when recall was intentional or when it was preceded by a deep-orienting task than when it was preceded by a shallow-orienting task. Middle-aged and older adults recalled more propositions when recall was intentional than when it was incidental, regardless of the depth of the orienting task. There were no significant differences in intentional recall. In addition, a significant age x orienting task x propositional level interaction indicated that younger adults recalled more of the main ideas of the text following deep processing, whereas the middle-aged and older adults recalled more of these ideas following intentional processing.

Kenichi Asano

2014-10-01

Full Text Available Several studies in Europe and North America have highlighted the importance of resignation or giving up. Research has shown that resignation is as important as goal attainment. Hence, this study examines, using path analysis, the effect of resignation orientation on goal disengagement and reengagement. Furthermore, this study attempts to clarify the implication of resignation orientation for elements of mental well-being. Questionnaires were completed by 261 Japanese college students. Results showed that proactive resignation orientation promotes reestablishment of alternative goals while negative resignation orientation encourages disengagement of the unattainable goals. The findings help explain the functional role of resignation orientation and can inform the development of treatment for resignation-related depression.

Animal Bodies, Colonial Subjects: (ReLocating Animality in Decolonial Thought

Directory of Open Access Journals (Sweden)

Billy-Ray Belcourt

2014-12-01

Full Text Available In this paper, I argue that animal domestication, speciesism, and other modern human-animal interactions in North America are possible because of and through the erasure of Indigenous bodies and the emptying of Indigenous lands for settler-colonial expansion. That is, we cannot address animal oppression or talk about animal liberation without naming and subsequently dismantling settler colonialism and white supremacy as political machinations that require the simultaneous exploitation and/or erasure of animal and Indigenous bodies. I begin by re-framing animality as a politics of space to suggest that animal bodies are made intelligible in the settler imagination on stolen, colonized, and re-settled Indigenous lands. Thinking through Andrea Smith’s logics of white supremacy, I then re-center anthropocentrism as a racialized and speciesist site of settler coloniality to re-orient decolonial thought toward animality. To critique the ways in which Indigenous bodies and epistemologies are at stake in neoliberal re-figurings of animals as settler citizens, I reject the colonial politics of recognition developed in Sue Donaldson and Will Kymlicka’s recent monograph, Zoopolis: A Political Theory of Animal Rights (Oxford University Press 2011 because it militarizes settler-colonial infrastructures of subjecthood and governmentality. I then propose a decolonized animal ethic that finds legitimacy in Indigenous cosmologies to argue that decolonization can only be reified through a totalizing disruption of those power apparatuses (i.e., settler colonialism, anthropocentrism, white supremacy, and neoliberal pluralism that lend the settler state sovereignty, normalcy, and futurity insofar as animality is a settler-colonial particularity.

No IT solution is known that can manage study participants, enhance quality of data, support re-contacting of participants, plan study visits, and keep track of informed consent procedures and recruitments that may be subject to change over time. In business settings management of personal is one of the major aspects of customer relationship management systems (CRMS). To evaluate whether CRMS are suitable IT solutions for study participant management in biomedical research. Three boards of experts in the field of biomedical research were consulted to get an insight into recent IT developments regarding study participant management systems (SPMS). Subsequently, a requirements analysis was performed with stakeholders of a major biomedical research project. The successive suitability evaluation was based on the comparison of the identified requirements with the features of six CRMS. Independently of each other, the interviewed expert boards confirmed that there is no generic IT solution for the management of participants. Sixty-four requirements were identified and prioritized in a requirements analysis. The best CRMS was able to fulfill forty-two of these requirements. The non-fulfilled requirements demand an adaption of the CRMS, consuming time and resources, reducing the update compatibility, the system's suitability, and the security of the CRMS. A specific solution for the SPMS is favored instead of a generic and commercially-oriented CRMS. Therefore, the development of a small and specific SPMS solution was commenced and is currently on the way to completion.

Embodied memory allows accurate and stable perception of hidden objects despite orientation change.

Rotating a scene in a frontoparallel plane (rolling) yields a change in orientation of constituent images. When using only information provided by static images to perceive a scene after orientation change, identification performance typically decreases (Rock & Heimer, 1957). However, rolling generates optic flow information that relates the discrete, static images (before and after the change) and forms an embodied memory that aids recognition. The embodied memory hypothesis predicts that upon detecting a continuous spatial transformation of image structure, or in other words, seeing the continuous rolling process and objects undergoing rolling observers should accurately perceive objects during and after motion. Thus, in this case, orientation change should not affect performance. We tested this hypothesis in three experiments and found that (a) using combined optic flow and image structure, participants identified locations of previously perceived but currently occluded targets with great accuracy and stability (Experiment 1); (b) using combined optic flow and image structure information, participants identified hidden targets equally well with or without 30° orientation changes (Experiment 2); and (c) when the rolling was unseen, identification of hidden targets after orientation change became worse (Experiment 3). Furthermore, when rolling was unseen, although target identification was better when participants were told about the orientation change than when they were not told, performance was still worse than when there was no orientation change. Therefore, combined optic flow and image structure information, not mere knowledge about the rolling, enables accurate and stable perception despite orientation change.

Additional renewable energy growth through small-scale community orientated energy policies

International Nuclear Information System (INIS)

Hain, J.J.; Ault, G.W.; Galloway, S.J.; Cruden, A.; McDonald, J.R.

2005-01-01

This paper summarises the energy policies that the UK Government has enacted in order to achieve its renewable targets by 2010. Current policies are designed primarily to support large-scale renewable projects through Renewable Obligation Certificates, Levy Exemption Certificates and capital grant schemes. Non-profit domestic and non-profit community renewable projects are also eligible for grant support. First-hand experience of privately owned renewable projects indicate that existing renewable policy is insufficient in its support of both small-scale and community-based profit oriented renewable energy (RE) schemes. Primary and secondary survey information suggests that people living in regions where RE will be situated may generally be inclined to support broader uses of renewables in these regions. Small-scale renewables can make a significant cumulative contribution to the RE mix. The results reported in this paper support the contention that the Government could go further towards approaching its targets through rural-focused changes to its energy incentive programmes

Molecular dynamics simulations on PGLa using NMR orientational constraints

NMR data obtained by solid state NMR from anisotropic samples are used as orientational constraints in molecular dynamics simulations for determining the structure and dynamics of the PGLa peptide within a membrane environment. For the simulation the recently developed molecular dynamics with orientational constraints technique (MDOC) is used. This method introduces orientation dependent pseudo-forces into the COSMOS-NMR force field. Acting during a molecular dynamics simulation these forces drive molecular rotations, re-orientations and folding in such a way that the motional time-averages of the tensorial NMR properties are consistent with the experimentally measured NMR parameters. This MDOC strategy does not depend on the initial choice of atomic coordinates, and is in principle suitable for any flexible and mobile kind of molecule; and it is of course possible to account for flexible parts of peptides or their side-chains. MDOC has been applied to the antimicrobial peptide PGLa and a related dimer model. With these simulations it was possible to reproduce most NMR parameters within the experimental error bounds. The alignment, conformation and order parameters of the membrane-bound molecule and its dimer were directly derived with MDOC from the NMR data. Furthermore, this new approach yielded for the first time the distribution of segmental orientations with respect to the membrane and the order parameter tensors of the dimer systems. It was demonstrated the deuterium splittings measured at the peptide to lipid ratio of 1/50 are consistent with a membrane spanning orientation of the peptide.

Oriented matroids—combinatorial structures underlying loop quantum gravity

Science.gov (United States)

Brunnemann, Johannes; Rideout, David

2010-10-01

We analyze combinatorial structures which play a central role in determining spectral properties of the volume operator (Ashtekar A and Lewandowski J 1998 Adv. Theor. Math. Phys. 1 388) in loop quantum gravity (LQG). These structures encode geometrical information of the embedding of arbitrary valence vertices of a graph in three-dimensional Riemannian space and can be represented by sign strings containing relative orientations of embedded edges. We demonstrate that these signature factors are a special representation of the general mathematical concept of an oriented matroid (Ziegler G M 1998 Electron. J. Comb.; Björner A et al 1999 Oriented Matroids (Cambridge: Cambridge University Press)). Moreover, we show that oriented matroids can also be used to describe the topology (connectedness) of directed graphs. Hence, the mathematical methods developed for oriented matroids can be applied to the difficult combinatorics of embedded graphs underlying the construction of LQG. As a first application we revisit the analysis of Brunnemann and Rideout (2008 Class. Quantum Grav. 25 065001 and 065002), and find that enumeration of all possible sign configurations used there is equivalent to enumerating all realizable oriented matroids of rank 3 (Ziegler G M 1998 Electron. J. Comb.; Björner A et al 1999 Oriented Matroids (Cambridge: Cambridge University Press)), and thus can be greatly simplified. We find that for 7-valent vertices having no coplanar triples of edge tangents, the smallest non-zero eigenvalue of the volume spectrum does not grow as one increases the maximum spin jmax at the vertex, for any orientation of the edge tangents. This indicates that, in contrast to the area operator, considering large jmax does not necessarily imply large volume eigenvalues. In addition we give an outlook to possible starting points for rewriting the combinatorics of LQG in terms of oriented matroids.

Eastwick, Paul W; Richeson, Jennifer A; Son, Deborah; Finkel, Eli J

2009-09-01

The present research examined the association of political orientation with ingroup favoritism in two live romantic contexts. In Study 1, White participants had sequential interactions with both a White and Black confederate and reported their romantic desire for each. In Study 2, both White and Black participants speed-dated multiple potential romantic partners and reported whether they would be interested in meeting each speed-dating partner again. In both studies, White participants' political conservatism positively predicted the strength of the ingroup-favoring bias: White conservatives were less likely than White liberals to desire Black (interracial) relative to White potential romantic partners. In contrast, Black participants' political conservatism negatively predicted the strength of the ingroup-favoring bias: Consistent with system-justification theory, Black conservatives were more likely than Black liberals to desire White (interracial) relative to Black potential romantic partners. Political orientation may be a key factor that influences the initiation of interracial romantic relationships.

Sexual Orientation as a Peripheral Cue in Advertising: Effects of Models' Sexual Orientation, Argument Strength, and Involvement on Responses to Magazine Ads.

Science.gov (United States)

Ivory, Adrienne Holz

2017-10-12

This study examines how sexual orientation of couples featured in magazine advertisements affects heterosexual viewers' responses using the elaboration likelihood model as a framework. A 3 × 2 × 2 × 3 experiment tested effects of sexual orientation, argument strength, involvement, and attitudes toward homosexuality on heterosexuals' attitudes toward the couple, advertisement, brand, and product, purchase intentions, and recall. Results indicate that consumers were accepting of ads with lesbian portrayals. Participants showed more negative attitudes toward gay male portrayals, but attitudes toward heterosexual and lesbian ads were similar. This effect was moderated by participants' attitudes toward homosexuals. Low-involvement consumers showed more negative attitudes toward homosexual portrayals than toward heterosexual portrayals, indicating that sexual orientation may have served as a peripheral cue negatively impacting attitudes toward the couple and ad under low elaboration. These effects were not observed for attitudes toward the brand and product, purchase intentions, or recall.

Gender role, sexual orientation and suicide risk.

There has been interest in the relationship between homosexuality, gender role and suicide risk. Though homosexuals are more likely to identify as cross-gender, research has not simultaneously examined sexual orientation and gender role in assessing suicide risk. In the current study, the unique and interactive effects of sexual orientation and gender role were assessed in regard to suicidal ideation, related psychopathology and measures of coping. 77 participants were recruited from an undergraduate psychology subject pool (n=47) or from gay, lesbian and transgender student organizations (n=30) and assessed on measures of gender role, homosexuality, and psychopathology. Consistent with expectations, cross-gender role (i.e., personality traits associated with the opposite sex) is a unique predictor of suicidal symptoms. Moreover, gender role accounted for more of the overall variance in suicidal symptoms, positive problem orientation, peer acceptance and support, than sexual orientation. After accounting for gender role, sexual orientation contributed little to the variance in suicidal symptoms, associated pathology and problem-solving deficits. There was no support for gender role by sexual orientation interaction effects. The cross-sectional nature of the data limits statements regarding causality. Cross-gendered individuals, regardless of sexual orientation, appear to have higher risk for suicidal symptoms. Researchers and clinicians should assess gender role in evaluations of youth samples.

The orientation distribution of tunneling-related quantities

Seif, W. M.; Refaie, A. I.; Botros, M. M.

2018-03-01

In the nuclear tunneling processes involving deformed nuclei, most of the tunneling-related quantities depend on the relative orientations of the participating nuclei. In the presence of different multipole deformations, we study the variation of a few relevant quantities for the α-decay and the sub-barrier fusion processes, in an orientation degree of freedom. The knocking frequency and the penetration probability are evaluated within the Wentzel-Kramers-Brillouin approximation. The interaction potential is calculated with Skyrme-type nucleon-nucleon interaction. We found that the width of the potential pocket, the Coulomb barrier radius, the penetration probability, the α-decay width, and the fusion cross-section follow consistently the orientation-angle variation of the radius of the deformed nucleus. The orientation distribution patterns of the pocket width, the barrier radius, the logarithms of the penetrability, the decay width, and the fusion cross-section are found to be highly analogous to pattern of the deformed-nucleus radius. The curve patterns of the orientation angle distributions of the internal pocket depth, the Coulomb barrier height and width, as well as the knocking frequency simulate inversely the variation of the deformed nucleus radius. The predicted orientation behaviors will be of a special interest in predicting the optimum orientations for the tunneling processes.

Selective enhancement of orientation tuning before saccades.

Ohl, Sven; Kuper, Clara; Rolfs, Martin

2017-11-01

Saccadic eye movements cause a rapid sweep of the visual image across the retina and bring the saccade's target into high-acuity foveal vision. Even before saccade onset, visual processing is selectively prioritized at the saccade target. To determine how this presaccadic attention shift exerts its influence on visual selection, we compare the dynamics of perceptual tuning curves before movement onset at the saccade target and in the opposite hemifield. Participants monitored a 30-Hz sequence of randomly oriented gratings for a target orientation. Combining a reverse correlation technique previously used to study orientation tuning in neurons and general additive mixed modeling, we found that perceptual reports were tuned to the target orientation. The gain of orientation tuning increased markedly within the last 100 ms before saccade onset. In addition, we observed finer orientation tuning right before saccade onset. This increase in gain and tuning occurred at the saccade target location and was not observed at the incongruent location in the opposite hemifield. The present findings suggest, therefore, that presaccadic attention exerts its influence on vision in a spatially and feature-selective manner, enhancing performance and sharpening feature tuning at the future gaze location before the eyes start moving.

Modern psychometrics for assessing achievement goal orientation: a Rasch analysis.

Muis, Krista R; Winne, Philip H; Edwards, Ordene V

2009-09-01

A program of research is needed that assesses the psychometric properties of instruments designed to quantify students' achievement goal orientations to clarify inconsistencies across previous studies and to provide a stronger basis for future research. We conducted traditional psychometric and modern Rasch-model analyses of the Achievement Goals Questionnaire (AGQ, Elliot & McGregor, 2001) and the Patterns of Adaptive Learning Scale (PALS, Midgley et al., 2000) to provide an in-depth analysis of the two most popular instruments in educational psychology. For Study 1, 217 undergraduate students enrolled in educational psychology courses participated. Thirty-four were male and 181 were female (two did not respond). Participants completed the AGQ in the context of their educational psychology class. For Study 2, 126 undergraduate students enrolled in educational psychology courses participated. Thirty were male and 95 were female (one did not respond). Participants completed the PALS in the context of their educational psychology class. Traditional psychometric assessments of the AGQ and PALS replicated previous studies. For both, reliability estimates ranged from good to very good for raw subscale scores and fit for the models of goal orientations were good. Based on traditional psychometrics, the AGQ and PALS are valid and reliable indicators of achievement goals. Rasch analyses revealed that estimates of reliability for items were very good but respondent ability estimates varied from poor to good for both the AGQ and PALS. These findings indicate that items validly and reliably reflect a group's aggregate goal orientation, but using either instrument to characterize an individual's goal orientation is hazardous.

SummaryOngoing political controversies around the world exemplify a long-standing and widespread preoccupation with the acceptability of homosexuality. Nonheterosexual people have seen dramatic surges both in their rights and in positive public opinion in many Western countries. In contrast, in much of Africa, the Middle East, the Caribbean, Oceania, and parts of Asia, homosexual behavior remains illegal and severely punishable, with some countries retaining the death penalty for it. Political controversies about sexual orientation have often overlapped with scientific controversies. That is, participants on both sides of the sociopolitical debates have tended to believe that scientific findings-and scientific truths-about sexual orientation matter a great deal in making political decisions. The most contentious scientific issues have concerned the causes of sexual orientation-that is, why are some people heterosexual, others bisexual, and others homosexual? The actual relevance of these issues to social, political, and ethical decisions is often poorly justified, however. © The Author(s) 2016.

Notched Strength of Woven Fabric Kenaf Composites with Different Fiber Orientations

Directory of Open Access Journals (Sweden)

Ahmad Hilton

2017-01-01

Full Text Available The awareness of implementing sustainable materials in construction industry is gaining good attention among engineers worldwide. Kenaf fibers are local renewable materials to combine with epoxy polymers matrix in producing lightweight composite materials which may replace imported synthetic fiber composites especially in developing countries. Other benefits of using kenaf fiber composites are relatively cheap, less abrasive and less hazardous during fabrication handling. Current study investigates parametric study on notched strength of woven fabric kenaf composite plates with different fiber orientations and circular hole sizes. Stress concentration occurred at the notch edge promotes to micro-damage events such as matrix cracking and fiber fracture as remote tensile loading applied. Current study showed that 0° fiber orientation gives optimum notched strength, plates with larger fiber tilting than 0° are associated with further strength reduction. Kenaf fibers give an alternative to material designers to opt woven fabric kenaf composites in low and medium load bearing applications.

Recommendations for citizen-oriented risk communication

International Nuclear Information System (INIS)

Fertmann, R.

2005-01-01

The purpose of recommendations for citizen-oriented risk communication should be to provide ''banisters'' which leave the players their freedom of action and allow them to adapt communicative structures to the situation at hand. Uncertainty and controversial issues at the levels of information, participation and assessment are identified as potential stumbling blocks in risk communication. The experiences gained in Hamburg shed a light on a diversity of processes in risk communication, which the present paper proceeds to evaluate. One of its essential recommendations is to have dialogic processes develop into forms of participation. A guide on risk communication which was formulated in the USA has been adapted to conditions as they prevail in Germany. The adapted version is more practically oriented than the rules of the EPA or the more recent CDC recommendations. Suitable success criteria include a fair procedure, a common baseline of what is known and not known, the acceptance of different assessment criteria, and the exchange of the pros and cons of different options

Moving event and moving participant in aspectual conceptions

Directory of Open Access Journals (Sweden)

Izutsu Katsunobu

2016-06-01

Full Text Available This study advances an analysis of the event conception of aspectual forms in four East Asian languages: Ainu, Japanese, Korean, and Ryukyuan. As earlier studies point out, event conceptions can be divided into two major types: the moving-event type and the moving-participant type, respectively. All aspectual forms in Ainu and Korean, and most forms in Japanese and Ryukyuan are based on that type of event conception. Moving-participant oriented Ainu and movingevent oriented Japanese occupy two extremes, between which Korean and Ryukyuan stand. Notwithstanding the geographical relationships among the four languages, Ryukyuan is closer to Ainu than to Korean, whereas Korean is closer to Ainu than to Japanese.

Estimating three-dimensional orientation of human body parts by inertial/magnetic sensing.

Sabatini, Angelo Maria

2011-01-01

User-worn sensing units composed of inertial and magnetic sensors are becoming increasingly popular in various domains, including biomedical engineering, robotics, virtual reality, where they can also be applied for real-time tracking of the orientation of human body parts in the three-dimensional (3D) space. Although they are a promising choice as wearable sensors under many respects, the inertial and magnetic sensors currently in use offer measuring performance that are critical in order to achieve and maintain accurate 3D-orientation estimates, anytime and anywhere. This paper reviews the main sensor fusion and filtering techniques proposed for accurate inertial/magnetic orientation tracking of human body parts; it also gives useful recipes for their actual implementation.

Electron re-scattering from aligned linear molecules using the R-matrix method

International Nuclear Information System (INIS)

Harvey, A G; Tennyson, J

2009-01-01

Electron re-scattering in a strong laser field provides an important probe of molecular structure and processes. The laser field drives the ionization of the molecule, followed by acceleration and subsequent recollision of the electron with the parent molecular ion, the scattered electrons carry information about the nuclear geometry and electronic states of the molecular ion. It is advantageous in strong field experiments to work with aligned molecules, which introduces extra physics compared to the standard gas-phase, electron-molecule scattering problem. The formalism for scattering from oriented linear molecules is presented and applied to H 2 and CO 2 . Differential cross sections are presented for (re-)scattering by these systems concentrating on the most common, linear alignment. In H 2 these cross sections show significant angular structure which, particularly for a scattering angle of 90 deg., are predicted to vary significantly between re-collisions stimulated by an even or an odd number of photons. In CO 2 these cross sections are zero indicating the necessity of using non-parallel alignment with this molecule.

Nagler, Philipp; Plechinger, Gerd; Schueller, Christian; Korn, Tobias [Institut fuer Experimentelle und Angewandte Physik, Universitaet Regensburg, 93040, Regensburg (Germany)

2016-02-15

ReS{sub 2} has recently emerged as a new member in the rapidly growing family of two-dimensional materials. Unlike MoS{sub 2} or WSe{sub 2}, the optical and electrical properties of ReS{sub 2} are not isotropic due to the reduced symmetry of the crystal. Here, we present layer-dependent Raman measurements of ReS{sub 2} samples ranging from monolayers to ten layers in the ultralow frequency regime. We observe layer breathing and shear modes which allow for easy assignment of the number of layers. Polarization-dependent measurements give further insight into the crystal structure and reveal an energetic shift of the shear mode which stems from the in-plane anisotropy of the shear modulus in this material.

THE LIMITED EFFECT OF COINCIDENT ORIENTATION ON THE CHOICE OF INTRINSIC AXIS (.).

Science.gov (United States)

Li, Jing; Su, Wei

2015-06-01

The allocentric system computes and represents general object-to-object spatial relationships to provide a spatial frame of reference other than the egocentric system. The intrinsic frame-of-reference system theory, which suggests people learn the locations of objects based upon an intrinsic axis, is important in research about the allocentric system. The purpose of the current study was to determine whether the effect of coincident orientation on the choice of intrinsic axis was limited. Two groups of participants (24 men, 24 women; M age = 24 yr., SD = 2) encoded different spatial layouts in which the objects shared the coincident orientation of 315° and 225° separately at learning perspective (0°). The response pattern of partial-scene-recognition task following learning reflected different strategies for choosing the intrinsic axis under different conditions. Under the 315° object-orientation condition, the objects' coincident orientation was as important as the symmetric axis in the choice of the intrinsic axis. However, participants were more likely to choose the symmetric axis as the intrinsic axis under the 225° object-orientation condition. The results suggest the effect of coincident orientation on the choice of intrinsic axis is limited.

Highlights: • We synthesized Co or Ni co-doped (Ca, RE)FeAs_2 with RE = La–Gd. • Co or Ni co-doping improved superconducting properties of all (Ca, RE)FeAs_2 samples. • T_c of (Ca, RE)FeAs_2 decreased with decreasing ionic radii of RE"3"+. • Eu doped samples showed exceptionally low T_c and long interlayer distance. • Long interlayer distance of Eu doped samples suggested co-existence of Eu"2"+ and Eu"3"+. - Abstract: Dependence of superconducting properties of (Ca, RE)(Fe, TM)As_2 [(Ca, RE)112, TM: Co, Ni)] on RE elements (RE = La–Gd) was systematically investigated. Improvement of superconducting properties by Co or Ni co-doping was observed for all (Ca, RE)112, which is similar to Co-co-doped (Ca, La)112 or (Ca, Pr)112. T_c of Co-co-doped samples decreased from 38 K for RE = La to 29 K for RE = Gd with decreasing ionic radii of RE"3"+. However, Co-co-doped (Ca, Eu)112 showed exceptionally low T_c = 21 K probably due to the co-existence of Eu"3"+ and Eu"2"+ suggested by longer interlayer distance d_F_e_–_F_e of (Ca, Eu)112 than other (Ca, RE)112.

The role of personal values in children's costly sharing and non-costly giving.

Science.gov (United States)

Abramson, Lior; Daniel, Ella; Knafo-Noam, Ariel

2018-01-01

This study examined whether children's values, global and abstract motivations serving as guiding principles, are organized similarly to those of adults, whether values can predict individual differences in children's sharing behaviors, and whether the normative nature of the situation influences the expression of these individual differences. Children (N=243, ages 5-12years) participated in a values ranking task as part of a visit to a science museum. The majority of children (n=150) also participated in a task examining costly sharing (i.e., sharing that results in giving up part of one's own resources) and non-costly giving (i.e., giving that does not influence one's own share). Starting from 5years of age, children showed a structure of values similar to that of adolescents and adults, specifically contrasting preferences for opposing values (i.e., self-transcendence with self-enhancement and openness to change with conservation). Importance given to self-transcendence values related positively to costly sharing but not to non-costly giving, indicating that in situations where it is more normative to share, individual differences in values are less expressed in children's actual sharing. In addition, children's sex and age moderated the relation between values and behavior. Children's values are an important aspect of their developing personalities. Taking them into consideration can greatly promote the research of prosocial and normative development as well as our understanding of individual differences in children's behavior.

Full Text Available The aim of this article is an attempt to determine which knowledge-oriented strategies can give metal industry enterprises the best results in achieving and maintaining a competitive advantage. To determine which of these discussed in the literature and implemented in various organizations knowledge-oriented strategies may prove to be the most effective in the metal industry, empirical research has begun. A chosen strategy of knowledge management and supporting strategies are the basis of a choice of methods and means of intended implementation. The choice of a specific knowledge management strategy may also result in the need for changes in an organization, particularly in an information system, internal communication, work organization and human resource management.

Ward, Sarah; Wiedemann, Lukas; Stinear, Cathy; Stinear, James; McDaid, Andrew

2017-07-01

Walking function post-stroke is characterized by asymmetries in gait cycle parameters and joint kinematics. The Re-Link Trainer is designed to provide kinematic constraint to the paretic lower limb, to guide a physiologically normal and symmetrical gait pattern. The purpose of this pilot study was to assess the immediate influence of the Re-Link Trainer on measures of gait symmetry in healthy adults. Participants demonstrated a significantly lower cadence and a 62% reduction in walking speed in the Re-Link Trainer compared to normal walking. The step length ratio had a significant increase from 1.0 during normal walking to 2.5 when walking in the Re-Link Trainer. The results from this pilot study suggest in its current iteration the Re-Link Trainer imposes an asymmetrical constraint on lower limb kinematics.

Lee, Hee Gyoun [Korea Polytechnic University, Siheung (Korea, Republic of)

2017-06-15

This study presents a simple method to control the seed orientation which leads to the various growth characteristics of a single grain REBCO (RE: rare-earth elements) bulk superconductors. Seed orientation was varied systematically from c-axis to a-axis with every 30 degree rotation around b-axis. Orientations of a REBCO single grain was successfully controlled by placing the seed with various angles on the prismatic indent prepared on the surface of REBCO powder compacts. Growth pattern was changed from cubic to rectangular when the seed orientation normal to compact surface was varied from c-axis to a-axis. Macroscopic shape change has been explained by the variation of the wetting angle of un-reacted melt depending on the interface energy between YBa2Cu3O7-y (Y123) grain and melt. Higher magnetic levitation force was obtained for the specimen prepared using tilted seed with an angle of 30 degree rotation around b-axis.

Re-fabrication and Instrumentation - resume and outlook

International Nuclear Information System (INIS)

Kleeman, Hans-Joerg; Oberlaender, Barbara C.

2005-01-01

The special technique ''re-fabrication and instrumentation'' applied at the Institute for Energy Technology (IFE) makes further testing and measuring of irradiated fuel rods in the Halden Boiling Water Reactor (HBWR) possible. Machines, necessary for such operations, were designed and produced at IFE in the years 1991-92. Hot Lab-operations called ''re-fabrication'' include all modifications necessary to load an irradiated fuel rod, commercial or experimental, into the Halden reactor for further testing. ''Instrumentation'' includes all operations necessary to fit instruments into an irradiated fuel rod segment to measure for instance the temperature in the centreline of the fuel stack, pressure increase in the fuel rod and/or changes of the rod length during reactor experiments. The machines used are referred to as: ''Cutting and Grinding Unit'' for machining of the canning; ''Freezing and Drilling Unit'' for drilling of the centreline thermocouple hole in the active fuel stack;''Welding and Drying Unit'' a TIG welding machine for the circumferential welds and the seal welding; and a hydraulic ''Encapsulation Bench''. The ''Welding and Drilling Unit'' includes also a ''He-leak test chamber'' and a ''Hydraulic Press''. In addition, different types of PIE methods are used in quality assurance and documenting of the work done with the fuel rod. For example neutron radiography, visual inspection, dimension measurement, free volume measurements, equipment to measure the flow capability through the fuel stack and different function tests of the measuring devices. This paper will give an overview of the work done so far with this equipment and give information about new equipment which will be installed soon to deal with even more complicated test fuel designs.

2011-08-26

An improved separation method for chlorophyll metabolites in Oriental tobacco leaf was developed. While Oriental leaf still gives the green color even after the curing process, little attention has been paid to the detailed composition of the remaining green pigments. This study aimed to identify the green pigments using non aqueous reversed phase chromatography (NARPC). To this end, liquid chromatograph (LC) equipped with a photo diode array detector (DAD) and an atmospheric pressure chemical ionization/mass spectrometer (APCI/MSD) was selected, because it is useful for detecting low polar non-volatile compounds giving green color such as pheophytin a. Identification was based on the wavelength spectrum, mass spectrum and retention time, comparing the analytes in Oriental leaf with the commercially available and synthesized components. Consequently, several chlorophyll metabolites such as hydroxypheophytin a, solanesyl pheophorbide a and solanesyl hydroxypheophorbide a were newly identified, in addition to typical green pigments such as chlorophyll a and pheophytin a. Chlorophyll metabolites bound to solanesol were considered the tobacco specific components. NARPC expanded the number of detectable low polar chlorophyll metabolites in Oriental tobacco leaf.

2017-09-01

In 2009, government of Malaysia has announced a National Renewable Energy Policy and Action Plan as part of their commitment to accelerate the growth in renewable energies (RE). However, an adoption of RE as a main source of energy is still at an early stage due to lack of public awareness and acceptance on RE. Up to date, there are insufficient studies done on the reasons behind this lack of awareness and acceptance. Therefore, this paper is interested to investigate the public acceptance towards development of RE by measuring their willingness to pay slightly more for energy generated from RE sources, denote as willingness level and whether the importance for the electricity to be supplied at absolute lowest possible cost regardless of source and environmental impact, denote as importance level and other socio-economic factors could improve their willingness level. Both qualitative and quantitative research methods are used to achieve the research objectives. A total of 164 respondents from local universities in Malaysia participated in a survey to collect this relevant information. Using Ordered Probit model, the study shows that among the relevant socio-economic factors, age seems to be an important factor to influence the willingness level of the respondents. This paper concludes that younger generation are more willing to pay slightly more for energy generated from RE sources as compared to older generation. One of the possible reason may due to better information access by the younger generation on the RE issues and its positive implication to the world. Finding from this paper is useful to help policy maker in designing RE advocacy programs that would be able to secure public participation. These efforts are important to ensure future success of the RE policy.

Report on the 2nd Research Coordination Meeting on The Development of Therapeutic Radiopharmaceuticals Based on 188Re and 90Y for Radionuclide. Working Document

International Nuclear Information System (INIS)

2010-01-01

Radionuclide therapy is practiced for the treatment of malignant disorders of various organs and tissues as well as for treating certain other diseases such as rheumatoid arthritis. Advances in understanding tumor biology as well as developments in peptide chemistry and monoclonal antibody technology are opening new opportunities for the development of therapeutic radiopharmaceuticals, thereby widening the scope of radionuclide therapy. In addition, particulate based radiopharmaceuticals are useful for treating hepatocarcinoma as well as in radiation synovectomy. With the establishment of new products the demand and application of therapeutic nuclear medicine is expected to grow rapidly. While there are a large number of radioisotopes proposed for targeted therapy, practical considerations had been limiting the number of usable isotopes. Generator-produced radionuclides are an attractive option for the large scale on-site availability of therapeutic isotopes. The IAEA’s CRP on the ‘Development of generator technologies for therapeutic radionuclides’ (2004-2007) was successful in developing technologies for the preparation of 188 W/ 188 Re and 90 Sr/ 90 Y generators for eluting 188 Re and 90 Y of high radionuclidic and chemical purity usable for research applications in the development of therapeutic radiopharmaceuticals. The IAEA’s CRP on ‘The development of therapeutic radiopharmaceuticals based on 188 Re and 90 Y for radionuclide therapy’ was formulated to focus on enhancing the capacity of the 90 Sr/ 90 Y generator; to develop and validate quality control methods for the generator eluate; and to develop therapeutic radiopharmaceuticals based on 188 Re and 90 Y. The first RCM of the CRP was held in Polatom, Warsaw, Poland from 30 June to 4 July 2008. The meeting reviewed the work going on in the different participating laboratories, and the facilities, expertise and capabilities of the different participating groups, and formulated the work plan of

The objective of this study was to explore the relationship between non-disclosure of sexual orientation to parents and sexual risk behaviors among gay and bisexual men who have sex with men (MSM) in China. A total of 295 eligible participants (gay n = 179, bisexual n = 116) were recruited from MSM venues and MSM organizations in Anhui Province, China. Overall, 16.6 % of participants chose to disclose their sexual orientation to parents. Fewer bisexual participants chose to disclose their sexual orientation than gay participants (9.5 vs. 21.2 %, p sexual orientation to parents was positively associated with the number of female sex partners (AOR = 3.40) and with engagement in unprotected anal intercourse with men (AOR = 2.49) among gay MSM, in the past 6 months. Our findings indicated that HIV/AIDS intervention programs should promote the disclosure of sexual orientation and should design interventions specific to gay and bisexual MSM separately.

The Institute of Medicine and The Joint Commission recommend routine documentation of patients' sexual orientation in health care settings. Currently, very few health care systems collect these data since patient preferences and health care professionals' support regarding collection of data about patient sexual orientation are unknown. To identify the optimal patient-centered approach to collect sexual orientation data in the emergency department (ED) in the Emergency Department Query for Patient-Centered Approaches to Sexual Orientation and Gender Identity study. An exploratory, sequential, mixed-methods design was used first to evaluate qualitative interviews conducted in the Baltimore, Maryland, and Washington, DC, areas. Fifty-three patients and 26 health care professionals participated in the qualitative interviews. Interviews were followed by a national online survey, in which 1516 (potential) patients (244 lesbian, 289 gay, 179 bisexual, and 804 straight) and 429 ED health care professionals (209 physicians and 220 nurses) participated. Survey participants were recruited using random digit dialing and address-based sampling techniques. Qualitative interviews were used to obtain the perspectives of patients and health care professionals on sexual orientation data collection, and a quantitative survey was used to gauge patients' and health care professionals' willingness to provide or obtain sexual orientation information. Mean (SD) age of patient and clinician participants was 49 (16.4) and 51 (9.4) years, respectively. Qualitative interviews suggested that patients were less likely to refuse to provide sexual orientation than providers expected. Nationally, 154 patients (10.3%) reported that they would refuse to provide sexual orientation; however, 333 (77.8%) of all clinicians thought patients would refuse to provide sexual orientation. After adjustment for demographic characteristics, only bisexual patients had increased odds of refusing to provide sexual

Participation: A Descending Road of the Metaphysical Cognition of Being

Full Text Available When we see in the world the fact that there are many beings, and we indicate that the particular beings exist in a compositional way, we face the task of learning about a new problem: how can we define and determine the relations between beings and between the elements within a being? Although the theory of participation has roots that go back to Plato, and so to a philosophy in which the pluralism of being was rejected and which accepted an identity-based conception of being, participation finds its ontological rational justification only (and ultimately in the pluralistic and compositional conception of being. With the description of participation as a “descending road” in the cognition of being, we are restricting ourselves to the presentation of how participation is understood in realistic metaphysics (while we shall leave aside the history of the question. We will show the aspects of participation that provide a foundation for wisdom-oriented cognition, and we will show the specific character of participation-oriented cognition as a “descending road.”

(Y 1-x Er x ) 2 Ba 4 Cu 7 O 15-y [(Y,Er)247] was synthesized for clarifying a magnetic role of Er ion. The three magnetization axes of (Y,Er)247 were obtained from tri-axial orientation using a modulated rotation magnetic field. Magnetic anisotropy of Er ion is roughly ten times higher than that for Y247 at room temperature. Importance of rare-earth ions was shown for reduction of required magnetic fields in the tri-axial magnetic orientation. We report the tri-axial grain-orientation effects under a modulated rotation magnetic field for (Y 1-x Er x ) 2 Ba 4 Cu 7 O y [(Y, Er)247]. The magnetic easy axis at room temperature was drastically changed around x ∼ 0.1; however, the Er-doping levels for the conversion of magnetic easy axes from the c-axis to the ab-direction and from the a- to b-axes were quite different. Tri-axial single-ion magnetic anisotropy of Er 3+ was roughly 10 times greater than tri-axial magnetic anisotropy generated by both the superconducting CuO 2 plane and the blocking Cu-O chain layer. An appropriate choice of rare-earth (RE) ions in RE-based cuprate superconductors enables the reduction of the required magnetic field for the production of bulks and thick films based on the magnetic orientation technique.

Although studies have shown that sexual orientation can be judged from faces, this research has not considered how age-related differences in perceivers or targets affect such judgments. In the current work, we evaluated whether accuracy differed among young adults (YA) and older adults (OA) for young and old men's faces by recruiting a sample of YA and OA in the lab, a community sample of sexual minority men, and a sample of online participants. We found that OA and YA judged sexual orientation with similar accuracy. Perceptions of gender atypicality mediated the difference in judging older and younger targets' sexual orientation. Although participants used positive affect to correctly discern sexual orientation regardless of target age, perceptions of masculinity were valid only for judgments of YA. © 2016 by the Society for Personality and Social Psychology, Inc.

Waste reduction by re-use of low activated material - 16035

International Nuclear Information System (INIS)

Ehrlicher, Ulrich; Pauli, Heinz

2009-01-01

A multidisciplinary institute, equipped with research reactors and accelerator-driven research installations produces and, in the case of PSI, collects radioactive waste on one hand and requires material, especially for shielding purpose, on the other hand. The legislative framework for radiation protection, financial reasons and limited storage capacity strongly force Paul Scherrer Institute and comparable facilities to minimize radioactive waste. Besides free release of inactive components, recycling and re-use of low-level radioactive material in controlled areas are the best means for waste minimization. The re-use of slightly activated steel plates as a shielding material and the recycling of irradiated reactor graphite as a filling material embedded in mortar may give examples and encouragement for similar activities. Besides the advantages for radiation protection, the financial benefit can be measured in millions of dollars. (authors)

Object-oriented fault tree evaluation program for quantitative analyses

Science.gov (United States)

Patterson-Hine, F. A.; Koen, B. V.

1988-01-01

Object-oriented programming can be combined with fault free techniques to give a significantly improved environment for evaluating the safety and reliability of large complex systems for space missions. Deep knowledge about system components and interactions, available from reliability studies and other sources, can be described using objects that make up a knowledge base. This knowledge base can be interrogated throughout the design process, during system testing, and during operation, and can be easily modified to reflect design changes in order to maintain a consistent information source. An object-oriented environment for reliability assessment has been developed on a Texas Instrument (TI) Explorer LISP workstation. The program, which directly evaluates system fault trees, utilizes the object-oriented extension to LISP called Flavors that is available on the Explorer. The object representation of a fault tree facilitates the storage and retrieval of information associated with each event in the tree, including tree structural information and intermediate results obtained during the tree reduction process. Reliability data associated with each basic event are stored in the fault tree objects. The object-oriented environment on the Explorer also includes a graphical tree editor which was modified to display and edit the fault trees.

Tuned by experience: How orientation probability modulates early perceptual processing.

Science.gov (United States)

Jabar, Syaheed B; Filipowicz, Alex; Anderson, Britt

2017-09-01

Probable stimuli are more often and more quickly detected. While stimulus probability is known to affect decision-making, it can also be explained as a perceptual phenomenon. Using spatial gratings, we have previously shown that probable orientations are also more precisely estimated, even while participants remained naive to the manipulation. We conducted an electrophysiological study to investigate the effect that probability has on perception and visual-evoked potentials. In line with previous studies on oddballs and stimulus prevalence, low-probability orientations were associated with a greater late positive 'P300' component which might be related to either surprise or decision-making. However, the early 'C1' component, thought to reflect V1 processing, was dampened for high-probability orientations while later P1 and N1 components were unaffected. Exploratory analyses revealed a participant-level correlation between C1 and P300 amplitudes, suggesting a link between perceptual processing and decision-making. We discuss how these probability effects could be indicative of sharpening of neurons preferring the probable orientations, due either to perceptual learning, or to feature-based attention.

Retrieving self-vocalized information: An event-related potential (ERP) study on the effect of retrieval orientation.

Science.gov (United States)

Rosburg, Timm; Johansson, Mikael; Sprondel, Volker; Mecklinger, Axel

2014-11-18

Retrieval orientation refers to a pre-retrieval process and conceptualizes the specific form of processing that is applied to a retrieval cue. In the current event-related potential (ERP) study, we sought to find evidence for an involvement of the auditory cortex when subjects attempt to retrieve vocalized information, and hypothesized that adopting retrieval orientation would be beneficial for retrieval accuracy. During study, participants saw object words that they subsequently vocalized or visually imagined. At test, participants had to identify object names of one study condition as targets and to reject object names of the second condition together with new items. Target category switched after half of the test trials. Behaviorally, participants responded less accurately and more slowly to targets of the vocalize condition than to targets of the imagine condition. ERPs to new items varied at a single left electrode (T7) between 500 and 800ms, indicating a moderate retrieval orientation effect in the subject group as a whole. However, whereas the effect was strongly pronounced in participants with high retrieval accuracy, it was absent in participants with low retrieval accuracy. A current source density (CSD) mapping of the retrieval orientation effect indicated a source over left temporal regions. Independently from retrieval accuracy, the ERP retrieval orientation effect was surprisingly also modulated by test order. Findings are suggestive for an involvement of the auditory cortex in retrieval attempts of vocalized information and confirm that adopting retrieval orientation is potentially beneficial for retrieval accuracy. The effects of test order on retrieval-related processes might reflect a stronger focus on the newness of items in the more difficult test condition when participants started with this condition.

Sex differences in face processing are mediated by handedness and sexual orientation.

Science.gov (United States)

Brewster, Paul W H; Mullin, Caitlin R; Dobrin, Roxana A; Steeves, Jennifer K E

2011-03-01

Previous research has demonstrated sex differences in face processing at both neural and behavioural levels. The present study examined the role of handedness and sexual orientation as mediators of this effect. We compared the performance of LH (left-handed) and RH (right-handed) heterosexual and homosexual male and female participants on a face recognition memory task. Our main findings were that homosexual males have better face recognition memory than both heterosexual males and homosexual women. We also demonstrate better face processing in women than in men. Finally, LH heterosexual participants had better face recognition than LH homosexual participants and also tended to be better than RH heterosexual participants. These findings are consistent with differences in the organisation and laterality of face-processing mechanisms as a function of sex, handedness, and sexual orientation.

The effects of paradigmatic orientations of education research and discourse

Science.gov (United States)

Smithson, John Lawrence

This essay presents an examination of contemporary disputes over methodological and epistemological foundations underlying inquiry within the field of education research; investigating the obstacles to communication and understanding found in scholarly exchanges occurring across competing paradigmatic orientations. Terminological challenges to cross-paradigmatic communication are examined, identifying three specific terminological difficulties, referred to as homonym, contextual, and onti-stemic problems. Nicholas Burbules' model of dialogue, based upon characteristics of convergence, divergence, inclusive and critical traits, is adopted and applied to a sample of cross-paradigmatic exchanges found in recent educational research journals. Examination of those exchanges reveals certain strategies associated with cross-paradigmatic communication. These strategies, labeled as trivialization, caricaturization, and re-direction, are shown to be detrimental to the mutual understanding of the interlocutors. The model is then extended to address examples of paradigmatic orientations within methodological and epistemological contexts in order to consider the relationship between the various orientations represented in the literature of interest. Methodological and epistemological orientations are shown to be loosely coupled, with unexpected shifts in paradigmatic values found among researchers' methodological and epistemological commitments. Finally, the nature of the relationship between competing paradigmatic orientations is examined, with particular attention given to four types of incommensurability (ontological, linguistic, epistemological, and values incommensurability). I conclude that, though difficult, cross-paradigmatic communication is necessary in order to provide a multi-paradigmatic perspective that takes us beyond the fractured picture of educational phenomena available from current research approaches.

Full Text Available Many researchers have said that there are differences in the ways people give direction between males and females, especially in spatial task (cardinal directions, topography, mileage, building, right/left markers (e.g., Lawton, 2001; Dabbs et al., 1998. Here, the thesis investigates what differences occur between both genders in giving direction. The respondents are 25 females and 25 males of fifth semester Binus University students majoring in English Literature. The respondents answered with a certain route from Binus’s Anggrek Campus to Senayan City. The study was conducted by qualitative and quantitative method. From the data analysis, the writer discovered that gender does affect in selecting the key words in explaining direction it is found that there were differences in choosing key words in giving direction between females and males. The difference is women use more than twice spatial references than men do. In terms of verbal abilities, it was confirmed that female use longer explanation. However, in other aspects such as serial orientation and maintenance words, the result is inconclusive.

Tack, C J; Plasschaert, A J M

2006-05-01

As part of a revised dental curriculum, a 3(rd) year module on medical subjects was developed based on a mixture of self-study and problem-oriented approach using cases. Pairs of students had to select a specific medical problem and solve a paper patient case using a problem-solving cycle. Results were presented in working groups and by writing an essay. The quality of the presentations was assessed by colleague students and by the teacher supervisor; the expert teacher in the field graded the essay. The results contributed for 40% to the overall grade of the module. A questionnaire filled out by 94% of the participating students showed that 85% of the students agreed in preferring this way of handling medical problems as compared with conventional, lecture-based education. Almost all of them enjoyed the provided opportunity to give a case presentation. The problem-oriented model was assessed as useful by 73% of the students. Knowledge concerning the topic chosen turned out to be higher than knowledge of other topics. Although this study cannot prove that this mode of education actually results in a better ability to cope with medical problems, it may contribute in several ways to the final competences in the area of general medicine in the undergraduate dental curriculum.

In recent years wellbeing has been linked increasingly with children's rights, often characterised as central to their realisation. Indeed it has been suggested that the two concepts are so intertwined that their pairing has become something of a mantra in the literature on childhood. This paper seeks to explore the nature of the relationship between wellbeing and participation rights, using a recently developed 'rights-based' measure of children's participation in school and community, the Children's Participation Rights Questionnaire (CPRQ), and an established measure of subjective wellbeing - KIDSCREEN-10. The data for the study came from the Kids' Life and Times (KLT) which is an annual online survey of Primary 7 children carried out in Northern Ireland. In 2013 approximately 3800 children (51 % girls; 49 % boys) from 212 schools participated in KLT. The findings showed a statistically significant positive correlation between children's overall scores on the KIDSCREEN-10 subjective wellbeing measure and their perceptions that their participation rights are respected in school and community settings. Further, the results indicated that it is the social relations/autonomy questions on KIDSCREEN-10 which are most strongly related to children's perceptions that their participation rights are respected. Exploration of the findings by gender showed that there were no significant differences in overall wellbeing; however girls had higher scores than boys on the social relations/autonomy domain of KIDSCREEN-10. Girls were also more positive than boys about their participation in school and community. In light of the findings from this study, it is suggested that what lies at the heart of the relationship between child wellbeing and children's participation rights is the social/relational aspects of both participation and wellbeing.

Oriented open-closed string theory revisited

International Nuclear Information System (INIS)

Zwiebach, B.

1998-01-01

String theory on D-brane backgrounds is open-closed string theory. Given the relevance of this fact, we give details and elaborate upon our earlier construction of oriented open-closed string field theory. In order to incorporate explicitly closed strings, the classical sector of this theory is open strings with a homotopy associative A ∞ algebraic structure. We build a suitable Batalin-Vilkovisky algebra on moduli spaces of bordered Ricmann surfaces, the construction of which involves a few subtleties arising from the open string punctures and cyclicity conditions. All vertices coupling open and closed strings through disks are described explicitly. Subalgebras of the algebra of surfaces with boundaries are used to discuss symmetries of classical open string theory induced by the closed string sector, and to write classical open string field theory on general closed string backgrounds. We give a preliminary analysis of the ghost-dilaton theorem. copyright 1998 Academic Press, Inc

Ho, Rong-Ming; Lu, Kai-Yuan; Lo, Ting-Ya; Dehghan, Ashkan; Shi, An-Chang; Prokopios, Georgopanos; Avgeropoulos, Apostolos

Controlling the orientation of nanostructured thin films of block copolymers (BCPs) is essential for next generation lithography. In the thin-film state, how to achieve the perpendicular orientation of the nanostructured microdomains remains challenging due to the interfacial effects from the air and also the substrate, especially for the blocks with silicon containing segments which usually have different surface energies, favoring parallel microdomain orientation. Here, we show that entropic effect can be used to control the orientation of BCP thin films. Specifically, we used the architecture of star-block copolymers consisting of polystyrene (PS) and poly(dimethylsiloxane) (PDMS) blocks to regulate the entropic contribution to the self-assembled nanostructures. Moreover, we aim to achieve the formation of perpendicular orientation from the air surface via surface plasma treatment to neutralize the interfacial energy difference. By combining the architecture effect (entropy effect) on BCP self-assembly and the surface plasma treatment (enthalpy effect), well-defined perpendicular PDMS microdomains in the PS-b-PDMS thin film can be formed from the bottom of non-neutral substrate and the top of the thin film surface, giving great potential for lithographic applications.

The Practical Realities of Giving Back

Directory of Open Access Journals (Sweden)

Ashton Bree Wesner

2014-07-01

Full Text Available In this thematic section, authors consider practical ways of giving back to the communities in which they conduct research. Each author discusses their evolving thoughts on how to give back in these practical ways. Some of these authors discuss giving back by giving money, food, rides, parties, and water bottles. In other cases, authors discuss giving back by creating jobs in the short or long term, grant writing, advocacy, and education. Story-telling is also a theme that many of the authors in this section discuss. For some authors, non-material forms of giving back are critical—simply maintaining social ties to the communities in which they worked, or sharing humor. The authors consider the utility of their attempts at giving back, and in some cases present their personal philosophy or guidelines on the subject.

Des terres pour l’agro-industrie internationale ? Un dilemme pour la politique foncière malgache

Full Text Available Les manœuvres d’appropriation foncière à grande échelle tentées fin 2008 par les entreprises Daewoo Logistics et Varun International, largement relayées par les médias et dénoncées par diverses organisations, ont participé à la déstabilisation du gouvernement Ravalomanana. Les montages de ces deux grands projets agro-industriels ont suivi des trajectoires différentes, l’un choisissant de contrôler d’immenses superficies par bail emphytéotique, l’autre privilégiant des formes de contractualisation de la production, mais tous deux ont été abandonnés face à des mouvements de contestation basés sur l’inaliénabilité de la « terre des ancêtres ». Le rejet de ces projets d’envergure encore inédite et en partie tournés vers des cultures d’exportation est compréhensible tant les retombées économiques et sociales paraissaient incertaines. Madagascar ne saurait néanmoins se priver d’investissements dans le secteur agricole, mais des choix de développement, orientés par une meilleure connaissance des processus en cours, restent à opérer en toute transparence, afin de combiner développement de l’agro-business et promotion des exploitations familiales. Pour l’instant, ces incertitudes marquent une politique foncière qui, même rénovée, hésite entre la formalisation de droits sur le sol au profit du plus grand nombre grâce à une décentralisation de la gestion foncière et l’octroi de vastes espaces à des firmes internationales suivant des procédures accélérées.

Reaalsuse re/presenteerimise strateegiad etenduskunstides / Strategies to Re-(Present Reality in the Performing Arts

Anneli Saro

2014-12-01

Full Text Available Contemporary theatre, and performing arts in general, no longer seems to be interested in the representation of illusion and reality. There seems to be an increasing emphasis on free play or/and an immediate presentation of reality. And, thus, the mainstream is moving towards the aesthetics of performance art and happenings, where recurrence is shunned and improvisation is emphasized on one hand, while the boundary between performance and reality is obscured on the other. This means that representative theatre, where performers and objects signify someone/something other, is retreating to give way to presentative theatre, where the performers and objects primarily signify themselves.  In the light of the aforementioned, this paper attempts to answer the following questions: how has the presentation of reality in theatre changed over the last forty years, how does presentative theatre differ from representative theatre and does presentative theatre arrive at a deeper/more objective understanding of reality or merely create yet another illusion? In order to answer these questions, the complicated relationship between art and reality as well as issues intrinsic to realist theatre are analysed. The author attempts to prove that it is difficult to find anything fundamentally new in 21st century theatre practice. A lot of the currently fashionable strategies are further developments of older waves, such as realism, or experiments placed in a new temporal and cultural context.  Considering the physical relationship between performing arts and reality, the third section of the paper analyses three strategies of (re-presenting reality: 1. Presenting the elements of reality on stage: performances of documentary material in as authentic a manner as possible, i.e. the self-presentations of so-called regular people or actors, etc. 2. Giving reality an artistic framework: audience tours through the city led by guide(s/performer(s or audio guides. 3

Market oriented approach by public utilities

Energy Technology Data Exchange (ETDEWEB)

Mantel, J J; Verkuil, J M

1989-08-01

Public utilities, especially the larger ones, have an image of being inefficient, technocratic and bureaucratic institutions, unresponsive to modern lifestyles, growing consumerism, differentiated customer needs and changing social values. Improving this image and increasing customer satisfaction requires the adoption of a systematic market oriented approach, based on an appropriate segmentation of the client and general public. This article gives the broad outline of such an approach followed by some generally applicable practical recommendations. Finally it stresses the importance of human aspects of organizational behaviour and, consequently, the crucial part of corporate culture. 2 figs., 1 tab.

The neural mechanisms of re-experiencing mental fatigue sensation: a magnetoencephalography study.

Full Text Available There have been several studies which have tried to clarify the neural mechanisms of fatigue sensation; however fatigue sensation has multiple aspects. We hypothesized that past experience related to fatigue sensation is an important factor which contributes to future formation of fatigue sensation through the transfer to memories that are located within specific brain structures. Therefore, we aimed to investigate the neural mechanisms of fatigue sensation related to memory. In the present study, we investigated the neural activity caused by re-experiencing the fatigue sensation that had been experienced during a fatigue-inducing session. Thirteen healthy volunteers participated in fatigue and non-fatigue experiments in a crossover fashion. In the fatigue experiment, they performed a 2-back test session for 40 min to induce fatigue sensation, a rest session for 15 min to recover from fatigue, and a magnetoencephalography (MEG session in which they were asked to re-experience the state of their body with fatigue that they had experienced in the 2-back test session. In the non-fatigue experiment, the participants performed a free session for 15 min, a rest session for 15 min, and an MEG session in which they were asked to re-experience the state of their body without fatigue that they had experienced in the free session. Spatial filtering analyses of oscillatory brain activity showed that the delta band power in the left Brodmann's area (BA 39, alpha band power in the right pulvinar nucleus and the left BA 40, and beta band power in the left BA 40 were lower when they re-experienced the fatigue sensation than when they re-experienced the fatigue-free sensation, indicating that these brain regions are related to re-experiencing the fatigue sensation. Our findings may help clarify the neural mechanisms underlying fatigue sensation.

Full Text Available Nowadays, multi-camera platforms combining nadir and oblique cameras are experiencing a revival. Due to their advantages such as ease of interpretation, completeness through mitigation of occluding areas, as well as system accessibility, they have found their place in numerous civil applications. However, automatic post-processing of such imagery still remains a topic of research. Configuration of cameras poses a challenge on the traditional photogrammetric pipeline used in commercial software and manual measurements are inevitable. For large image blocks it is certainly an impediment. Within theoretical part of the work we review three common least square adjustment methods and recap on possible ways for a multi-camera system orientation. In the practical part we present an approach that successfully oriented a block of 550 images acquired with an imaging system composed of 5 cameras (Canon Eos 1D Mark III with different focal lengths. Oblique cameras are rotated in the four looking directions (forward, backward, left and right by 45° with respect to the nadir camera. The workflow relies only upon open-source software: a developed tool to analyse image connectivity and Apero to orient the image block. The benefits of the connectivity tool are twofold: in terms of computational time and success of Bundle Block Adjustment. It exploits the georeferenced information provided by the Applanix system in constraining feature point extraction to relevant images only, and guides the concatenation of images during the relative orientation. Ultimately an absolute transformation is performed resulting in mean re-projection residuals equal to 0.6 pix.

Spontaneous growth of whiskers on RE-bearing intermetallic compounds of Sn-RE, In-RE, and Pb-RE

International Nuclear Information System (INIS)

Liu Meng; Xian Aiping

2009-01-01

A phenomenon of the whiskers growth on the bulk rare earth (RE)-intermetallic compounds of NdSn 3 , NdIn 3 , and LaPb 3 is reported. The whiskers formed spontaneously on all of the RE-intermetallic compounds after exposed to room ambience (21-28 deg. C/20-56% RH, relative humidity) for several days. Among the samples, the propensity of whisker growth for NdSn 3 is the strongest, on which the tin whiskers were flourishing and covered all of the surfaces after exposed to room ambience for 22 days; while LaPb 3 is the secondary and NdIn 3 is the last one. Observed by SEM, the whiskers were exhibited as different morphology, size, and number density. The XRD analysis confirms the existence of RE(OH) 3 after whiskers formed, also, the weight gain curve of the samples exposed to room ambience supports that a spontaneous chemical reaction of the RE-intermetallic compounds with water in room ambience takes place. In discussion, it is proposed that the fresh metal atoms released by the chemical reaction could be causative to result in nucleation and spontaneous growth of the whiskers, while the anisotropy of crystal structure could be a reason to understand the difference of the whisker growth behaviors between Sn and Pb.

Drawing from developmental and cultural adaptation perspectives and using a longitudinal design, this study examined: (a) mean-level changes in Mexican-origin adolescents’ cultural orientations and adjustment from early to late adolescence; and (b) bidirectional associations between cultural orientations and adjustment using a cross-lag panel model. Participants included 246 Mexican-origin, predominantly immigrant families that participated in home interviews and a series of nightly phone calls when target adolescents were 12 years and 18 years of age. Girls exhibited more pronounced declines in traditional gender role attitudes than did boys, and all youth declined in familism values, time spent with family, and involvement in Mexican culture. Bidirectional relations between cultural orientations and adjustment emerged, and some associations were moderated by adolescent nativity and gender. PMID:22966929

We assessed the effect of basic orientation to the simulation environment on anxiety, confidence, and clinical decision making. Twenty-four graduating medical students participated in a two-week surgery preparatory curriculum, including three simulations. Baseline anxiety was assessed pre-course. Scenarios were completed on day 2 and day 9. Prior to the first simulation, participants were randomly divided into two groups. Only one group received a pre-simulation orientation. Before the second simulation, all students received the same orientation. Learner anxiety was reported immediately preceding and following each simulation. Confidence was assessed post-simulation. Performance was evaluated by surgical faculty. The oriented group experienced decreased anxiety following the first simulation (p = 0.003); the control group did not. Compared to the control group, the oriented group reported less anxiety and greater confidence and received higher performance scores following all three simulations (all p simulation orientation reduces anxiety while increasing confidence and improving performance.

Full Text Available The present work is a synthesis of my Master’s Degree dissertation in which I tried toidentify the factors that have influenced the implementation of Participatory InstitutionalEvaluation in a public primary school of the periphery of Campinas, a Brazilianmunicipality in the state of Sao Paulo. Based on the concept of negotiated quality, theenactment of the institutional evaluation model proposed required the constitution ofan Evaluation Commission by representatives of diverse actors of the school community.The research consisted of a qualitative case study, using data collected from October2005 to December 2006, when I entered the school environment in order to support theschool to develop its evaluation process. Four categories of analysis were constructedto reflect on the school political pedagogical project, the educational culture of theschool principal, the nuances of participation and the potentialities of participativeinstitutional evaluation. The results acknowledge the potential of participative institutionalevaluation as a means for democratic management and for technical and politicalcapacity building at the school level aimed at overcoming problems faced by theschool.

Full Text Available Background The relation of positive orientation (a basic predisposition to think positively of oneself, one’s life and one’s future and personality traits is still disputable. The purpose of the described research was to verify the hypothesis that positive orientation has predictive efficiency beyond the five-factor model. Participants and procedure One hundred and thirty participants (at the mean age M = 24.84 completed the following questionnaires: the Self-Esteem Scale (SES, the Satisfaction with Life Scale (SWLS, the Life Orientation Test-Revised (LOT-R, the Positivity Scale (P-SCALE, the NEO Five Factor Inventory (NEO-FFI, the Self-Concept Clarity Scale (SCC, the Generalized Self-Efficacy Scale (GSES and the Life Engagement Test (LET. Results The introduction of positive orientation as an additional predictor in the second step of regression analyses led to better prediction of the following variables: purpose in life, self-concept clarity and generalized self-efficacy. This effect was the strongest for predicting purpose in life (i.e. 14% increment of the explained variance. Conclusions The results confirmed our hypothesis that positive orientation can be characterized by incremental validity – its inclusion in the regression model (in addition to the five main factors of personality increases the amount of explained variance. These findings may provide further evidence for the legitimacy of measuring positive orientation and personality traits separately.

Multiple emotions: a person-centered approach to the relationship between intergroup emotion and action orientation.

Fernando, Julian W; Kashima, Yoshihisa; Laham, Simon M

2014-08-01

Although a great deal of research has investigated the relationship between emotions and action orientations, most studies to date have used variable-centered techniques to identify the best emotion predictor(s) of a particular action. Given that people frequently report multiple or blended emotions, a profitable area of research may be to adopt person-centered approaches to examine the action orientations elicited by a particular combination of emotions or "emotion profile." In two studies, across instances of intergroup inequality in Australia and Canada, we examined participants' experiences of six intergroup emotions: sympathy, anger directed at three targets, shame, and pride. In both studies, five groups of participants with similar emotion profiles were identified by cluster analysis and their action orientations were compared; clusters indicated that the majority of participants experienced multiple emotions. Each action orientation was also regressed on the six emotions. There were a number of differences in the results obtained from the person-centered and variable-centered approaches. This was most apparent for sympathy: the group of participants experiencing only sympathy showed little inclination to perform prosocial actions, yet sympathy was a significant predictor of numerous action orientations in regression analyses. These results imply that sympathy may only prompt a desire for action when experienced in combination with other emotions. We suggest that the use of person-centered and variable-centered approaches as complementary analytic strategies may enrich research into not only the affective predictors of action, but emotion research in general.

Full Text Available This study will re-think A Long Story under the guidance of Daniel Frampton’s perspective of “filmosophy” which theorises film as a ‘being’ independent from any external effect, and acknowledges that film  has a ‘mind’ and is ‘able to think’ in its own way. To be clear on re-thinking how A Long Story ‘thinks’ of the concept of ‘recurrence’ in its dramatic structure, this study first will give a detailed explanation of “filmosophy”. Then, it will elaborate the particular ‘intentions’ and ‘choices’ that the film is responsible of whilst constructing itself upon the idea of ‘recurrence’. Finally, this study will focus on a particular scene and explain its significance on locating ‘recurrence’ as the ‘whole knowledge’ the film keeps in mind.

Zhan, Yujie; Wang, Mo; Shi, Junqi

2015-09-01

Bridge employment refers to the labor force participation after people retire from career jobs. It is becoming a prevalent phenomenon for retirees transitioning from employment to complete work withdrawal. Building on existing literature on retirement transition and older adults' work motivation, the present study examined the effects of 3 motivational orientations (i.e., status striving, communion striving, and generativity striving) in relating to retirees' bridge employment participation (i.e., bridge employment status and bridge employment work hours). This study also applied the social gender role theory to examine the effect of gender in moderating the effects of motivational orientations. Data from 507 Chinese retirees in Beijing revealed that communion striving and generativity striving were positively related to bridge employment participation. Further, gender moderated the effect of status striving such that status striving was positively related to bridge employment participation for male retirees but not for female retirees. In addition, exploratory analysis was conducted to examine the effects of the same set of motivational orientations on postretirement volunteering activities. Results showed that status striving was negatively related to volunteering after retirement. The findings are discussed in terms of their theoretical implications for the bridge employment literature and practical implications for recruiting and retaining older workers.

Peixoto, Maria Manuela; Nobre, Pedro

2016-01-01

Personality traits, namely neuroticism, have been suggested as vulnerability factors for the development and maintenance of sexual dysfunction in heterosexual samples. However, no evidence was found regarding homosexual samples. This study aimed to analyze the differences on personality traits between heterosexual and homosexual men and women with and without sexual problems. Participants were 285 individuals (142 men, 143 women) who completed a web-based survey. Participants answered the NEO Five-Factor Inventory, the Brief Symptomatology Inventory, and questions regarding sexual problems. The groups of men and women with and without sexual problems were matched for sociodemographic variables. A 2 (Group) × 2 (Sexual Orientation) multivariate analysis of covariance was conducted separately for each gender. Results indicated a significant main effect for group and for sexual orientation in male and female samples. Men with sexual problems scored higher on neuroticism, whereas women with sexual problems scored higher on neuroticism and lower on extraversion when compared with healthy controls, regardless of sexual orientation. In addition, gay men scored higher on neuroticism and lesbian women scored higher on conscientiousness compared with the heterosexual groups. The present findings emphasize the central role of neuroticism on sexual problems in both men and women regardless of sexual orientation.

Are larks future-oriented and owls present-oriented? Age- and sex-related shifts in chronotype-time perspective associations.

Science.gov (United States)

Nowack, Kati; van der Meer, Elke

2013-12-01

The chronotype (morningness/eveningness) relates to individual differences in circadian preferences. Time perspective (past, present, future) refers to the preference to rely on a particular temporal frame for decision-making processes and behavior. First evidence suggests that future time perspective is associated with greater morningness and present time perspective with greater eveningness. However, little is known about how chronotype-time perspective relationships may alter over the life span. This present study investigated links between chronotype and time perspective more thoroughly by taking age and sex into account as well. Seven hundred six participants aged between 17 and 74 completed German adaptations of the Morningness--Eveningness Questionnaire (MEQ) and Zimbardo Time Perspective Inventory (ZTPI). Controlling for age and sex, relationships between morningness and future time perspective as well as between eveningness and present time perspective were replicated. These findings were supported by significant associations between time perspective and midpoint of sleep. Future time perspective was linked to earlier midpoints of sleep, indicating an early chronotype. Present time perspective was associated with later midpoints of sleep, indicating a late chronotype. However, age and sex had an impact on the chronotype-time perspective relationships. In all age groups, male larks were more future-oriented and less present-oriented, male owls more present-oriented and less future-oriented. The same conclusion could be drawn for female adolescents and young adults. For female adults above 30, there was no interrelationship between morningness and future time perspective but between eveningness and past time perspective. Female adult owls were more present-oriented as well as more past-oriented. Female adult larks were less present-oriented and less past-oriented. Findings are discussed in the light of neuroendocrine and serotonergic functioning.

2015-10-01

Consumer participation in design, delivery and evaluation of occupational therapy educational programs is a recently introduced requirement for accreditation. It aligns with the principle of recovery, which underpins Australian mental health policy. Graduates' capabilities for recovery-oriented practice are thought to be enhanced through learning from consumers' lived experience. This structured literature review evaluates the current evidence for mental health consumer participation in health professional education to inform occupational therapy educators. Searches were completed in five online databases, one journal and published reading lists on the topic. Studies were included if they addressed mental health consumer participation in health professional education programs, were published in peer reviewed journals between 2000 and 2014 and were in English. Articles were critically reviewed, and analysed for key findings related to stages of the educational process and recovery-oriented practice capabilities. An emerging body of evidence for consumer participation in mental health education was identified. Studies are characterised by a lack of quality and a low to medium level of evidence. Findings relate to design, planning, delivery and evaluation of education as well as to most aspects of recovery-oriented practice. Emphases on exploratory research and proximal outcomes, and a reliance on published outcome measurement instruments designed for other purposes are key limitations in this body of evidence. This study identifies a weak evidence base for the requirement for consumer participation in occupational therapy programs, specifically related to mental health curricula. A research agenda is proposed in response. © 2015 Occupational Therapy Australia.

The paper presents the experience of re-interpretation of Beethoven’s Ninth Symphony sounding in the films directed by Kubrick (A Clockwork Orange and Tarkovsky (Nostalghia. This refers to the total rethinking of the classical art sample carried out within a cultural context due to the "past life" of a musical work. Consideration of filmmusic performed in reliance on the rhetorical canon as the trinity of Ethos, Logos, and Pathos. In the terminology of Bakhtin, Logos and Ethos are identified at the level of cognitive and ethical aspects of content. As a result, their co-existence creates Pathos like a unit, which "produced and perceived via art". Giving aware of the fact that in "perception a musical work, the intense deepening of ethical moment is permissible" [Bakhtin], author connects filmmusic specific feature with the experience of re-expression of musical language into pictorial speech.

Giving what one should: explanations for the knowledge-behavior gap for altruistic giving.

Science.gov (United States)

Blake, Peter R

2018-04-01

Several studies have shown that children struggle to give what they believe that they should: the so-called knowledge-behavior gap. Over a dozen recent Dictator Game studies find that, although young children believe that they should give half of a set of resources to a peer, they typically give less and often keep all of the resources for themselves. This article reviews recent evidence for five potential explanations for the gap and how children close it with age: self-regulation, social distance, theory of mind, moral knowledge and social learning. I conclude that self-regulation, social distance, and social learning show the most promising evidence for understanding the mechanisms that can close the gap. Copyright © 2017 Elsevier Ltd.

In prostate radiation therapy, inter-fractional organ motion/deformation has posed significant challenges on reliable daily dose delivery. To correct for this issue, off-line re-optimization and online re-positioning have been used clinically. In this paper, we propose an adaptive images guided radiation therapy (AIGRT) scheme that combines these two correction methods in an anatomy-driven fashion. The AIGRT process first tries to find a best plan for the daily target from a plan pool, which consists of the original CT plan and all previous re-optimized plans. If successful, the selected plan is used for daily treatment with translational shifts. Otherwise, the AIGRT invokes the re-optimization process of the CT plan for the anatomy of the day, which is afterward added to the plan pool as a candidate for future fractions. The AIGRT scheme is evaluated by comparisons with daily re-optimization and online re-positioning techniques based on daily target coverage, organs at risk (OAR) sparing and implementation efficiency. Simulated treatment courses for 18 patients with re-optimization alone, re-positioning alone and AIGRT shows that AIGRT offers reliable daily target coverage that is highly comparable to daily re-optimization and significantly improves from re-positioning. AIGRT is also seen to provide improved OAR sparing compared to re-positioning. Apart from dosimetric benefits, AIGRT in addition offers an efficient scheme to integrate re-optimization to current re-positioning-based IGRT workflow.

2018-01-01

Pedagogical content knowledge (PCK) is an essential kind of knowledge that teacher have for teaching particular content to particular students for enhance students' understanding, therefore, teachers with adequate PCK can give content to their students in an understandable way rather than transfer subject matter knowledge to learner. This study explored science student teachers' PCK for teaching science using Content representation base methodology. Research participants were 68 4th year science student teachers from department of General Science, faculty of Education, Phuket Rajabhat University. PCK conceptualization for teaching science by Magnusson et al. (1999) was applied as a theoretical framework in this study. In this study, Content representation (CoRe) by Loughran et al. (2004) was employed as research methodology in the lesson preparation process. In addition, CoRe consisted of eight questions (CoRe prompts) that designed to elicit and portray teacher's PCK for teaching science. Data were collected from science student teachers' CoRes design for teaching a given topic and student grade. Science student teachers asked to create CoRes design for teaching in topic `Motion in one direction' for 7th grade student and further class discussion. Science student teachers mostly created a same group of science concepts according to subunits of school science textbook rather than planned and arranged content to support students' understanding. Furthermore, they described about the effect of student's prior knowledge and learning difficulties such as students' knowledge of Scalar and Vector quantity; and calculating skill. These responses portrayed science student teacher's knowledge of students' understanding of science and their content knowledge. However, they still have inadequate knowledge of instructional strategies and activities for enhance student learning. In summary, CoRes design can represented holistic overviews of science student teachers' PCK related

Ryska, Todd A

2003-05-01

The purpose of the study was to evaluate measures of competitiveness, motivational orientation, and perceived purposes of participation as predictors of sportsmanship in a sample of 319 young participants in sports. Hierarchical regression analyses indicated that intrinsic reasons for sports participation, such as enhanced self-esteem and task mastery, predicted higher levels on multiple dimensions of sportsmanship, above and beyond the influence of competitiveness, motivational orientation, and various demographic variables. In contrast, extrinsic purposes for participation in sports, such as to obtain social status and a high-status career, contributed to lower levels on 3 of the 4 sportsmanship dimensions. These results are discussed with regard to developing a competitive sport setting that promotes ethical standards of interpersonal behavior for young participants in sports.

The article presents a best practice model that can be utilized by food system actors to assist with (re)building trust in the food system, before, during and after a food incident defined as 'any situation within the food supply chain where there is a risk or potential risk of illness or confirmed illness or injury associated with the consumption of a food or foods' (Commonwealth of Australia. National Food Incident Response Protocol. Commonwealth of Australia, Canberra, 2012). Interviews were undertaken with 105 actors working within the media, food industry and food regulatory settings across Australia, New Zealand (NZ) and the United Kingdom (UK). Interview data produced strategy statements, which indicated participant views on how to (re)build consumer trust in the food system. These included: (i) be transparent, (ii) have protocols and procedures in place, (iii) be credible, (iv) be proactive, (v) put consumers first, (vi) collaborate with stakeholders, (vii) be consistent, (viii) educate stakeholders and consumers, (ix) build your reputation and (x) keep your promises. A survey was designed to enable participants to indicate their agreement/disagreement with the ideas, rate their importance and provide further comment. The five strategies considered key to (re)building consumer trust were used to develop a model demonstrating best practice strategies for (re)building consumer trust in the food system before, during and after a food incident. In a world where the food system is increasingly complex, strategies for (re)building and fostering consumer trust are important. This study offers a model to do so which is derived from the views and experiences of actors working across the food industry, food regulation and the media. © The Author 2016.

The self-orientation of mammalian cells in optical tweezers—the importance of the nucleus

International Nuclear Information System (INIS)

Perney, Nicolas M B; Horak, Peter; Melvin, Tracy; Hanley, Neil A

2012-01-01

Here we present the first evidence showing that eukaryotic cells can be stably trapped in a single focused Gaussian beam with an orientation that is defined by the nucleus. A mammalian eukaryotic cell (in suspension) is trapped and is re-oriented in the focus of a linearly polarized Gaussian beam with a waist of dimension smaller than the radius of the nucleus. The cell reaches a position relative to the focus that is dictated by the nucleus and nuclear components. Our studies illustrate that the force exerted by the optical tweezers at locations within the cell can be predicted theoretically; the data obtained in this way is consistent with the experimental observations.

Radionuclide therapy is practiced for the treatment of malignant disorders of various organs and tissues as well as for treating certain other diseases such as rheumatoid arthritis. Advances in understanding tumor biology as well as developments in peptide chemistry and monoclonal antibody technology are opening new opportunities for the development of therapeutic radiopharmaceuticals, thereby widening the scope of radionuclide therapy. In addition, particulate based radiopharmaceuticals are useful for treating hepatocarcinoma as well as in radiation synovectomy. With the establishment of new products the demand and application of therapeutic nuclear medicine is expected to grow rapidly. While there are a large number of radioisotopes proposed for targeted therapy, practical considerations had been limiting the number of usable isotopes. Generator-produced radionuclides are an attractive option for the large scale on-site availability of therapeutic isotopes. The IAEA’s CRP on the ‘Development of generator technologies for therapeutic radionuclides’ (2004-2007) was successful in developing technologies for the preparation of {sup 188}W/{sup 188}Re and {sup 90}Sr/{sup 90}Y generators for eluting {sup 188}Re and {sup 90}Y of high radionuclidic and chemical purity usable for research applications in the development of therapeutic radiopharmaceuticals. The IAEA’s CRP on ‘The development of therapeutic radiopharmaceuticals based on {sup 188}Re and {sup 90}Y for radionuclide therapy’ was formulated to focus on enhancing the capacity of the {sup 90}Sr/{sup 90}Y generator; to develop and validate quality control methods for the generator eluate; and to develop therapeutic radiopharmaceuticals based on {sup 188}Re and {sup 90}Y. The first RCM of the CRP was held in Polatom, Warsaw, Poland from 30 June to 4 July 2008. The meeting reviewed the work going on in the different participating laboratories, and the facilities, expertise and capabilities of the different

The risks associated with consumer magazines giving advice on complementary therapies.

Mantle, Fiona

The increased popularity of complementary and alternative medicine (CAM) has led to increased demand for information on it, giving rise to the concept of "new experts". However, there is concern about the quality and accuracy of this information, much of which is published in popular magazines and written by contributors with no medical qualifications. To examine the extent of CAM product advice in women's and health magazines, and the potential for adverse drug/herbal interaction. Fifteen women's magazines were examined over one month. A total of 150 articles were identified, of which 131 were written by non-medically qualified contributors, mainly journalists. Out of the 150, 95 discussed ingested herbs which had the potential for adverse interactions and are contraindicated for certain groups. The findings have legal and ethical implications. The re-evaluation of the journalists' code of conduct to reflect this development in journalism should be considered.

Ongley, Sophia F; Nola, Marta; Malti, Tina

2014-01-01

This study investigated the role of moral reasoning and moral emotions (i.e., sympathy and guilt) in the development of young children's donating behavior (N = 160 4- and 8-year-old children). Donating was measured through children's allocation of resources (i.e., stickers) to needy peers and was framed as a donation to "World Vision." Children's sympathy was measured with both self- and primary caregiver-reports and participants reported their anticipation of guilt feelings following actions that violated prosocial moral norms, specifically the failure to help or share. Participants also provided justifications for their anticipated emotions, which were coded as representing moral or non-moral reasoning processes. Children's moral reasoning emerged as a significant predictor of donating behavior. In addition, results demonstrated significant developmental and gender effects, with 8-year-olds donating significantly more than 4-year-olds and 4-year-old girls making higher value donations than boys of the same age. We discuss donation behaviors within the broader context of giving and highlight the moral developmental antecedents of giving behaviors in childhood.

A phenomenon of the whiskers growth on the bulk rare earth (RE)-intermetallic compounds of NdSn{sub 3}, NdIn{sub 3}, and LaPb{sub 3} is reported. The whiskers formed spontaneously on all of the RE-intermetallic compounds after exposed to room ambience (21-28 deg. C/20-56% RH, relative humidity) for several days. Among the samples, the propensity of whisker growth for NdSn{sub 3} is the strongest, on which the tin whiskers were flourishing and covered all of the surfaces after exposed to room ambience for 22 days; while LaPb{sub 3} is the secondary and NdIn{sub 3} is the last one. Observed by SEM, the whiskers were exhibited as different morphology, size, and number density. The XRD analysis confirms the existence of RE(OH){sub 3} after whiskers formed, also, the weight gain curve of the samples exposed to room ambience supports that a spontaneous chemical reaction of the RE-intermetallic compounds with water in room ambience takes place. In discussion, it is proposed that the fresh metal atoms released by the chemical reaction could be causative to result in nucleation and spontaneous growth of the whiskers, while the anisotropy of crystal structure could be a reason to understand the difference of the whisker growth behaviors between Sn and Pb.

Effect of substituted rare earth element in (Yb1-xNd x)Ba2Cu3O y thin film on growth orientation and superconducting properties

We studied the orientation and superconducting properties in (Yb 1-x Nd x )Ba 2 Cu 3 O y (Yb/Nd123) thin films as a function of Yb/Nd composition ratio x. As a results, we needed so high oxygen pressure as to increase x for obtaining the c-axis oriented films. J c -B curves in the Yb/Nd123 thin films were superior to that in YBa 2 Cu 3 O y thin film. Since a RE fluctuation in a composition in the Yb/Nd123 thin films was observed with TEM-EDX, we speculated the pinning centers in the Yb/Nd123 thin films were strongly affected by the RE fluctuation

Most smoking cessation programs lack strategies to reach relapsed participants and encourage a new quit attempt. We used a multimodal intervention to encourage past quitline registry participants to recycle into services. We invited 3,510 past quitline participants back to quitline services, using messages consecutively delivered through Interactive Voice Response (IVR), followed by postcard and email reminders, 2 Short Messaging Services (SMS) texts, and a final cycle of IVR. The primary study outcome was recycling into a new quitline-assisted quit attempt. We used statistical analyses to assess rates and predictors of recycling (socioeconomic, health- and tobacco-related variables) with study participants and compared the study sample with registry participants not selected for the study (comparison group). Quitline services were re-initiated by 12.2% of the intervention sample and 1.9% of the comparison group (z = 6.03, P < .001, effect size of 0.44). Most re-enrollments were done via direct IVR-transfer to the quitline. Predictors of re-enrollment were age (odds ratio [OR] = 1.45 for every 10 years of age; 95% confidence interval [CI], 1.34-1.57), number of years smoking (OR = 1.27; 95% CI, 1.18-1.36), and reporting cancer (OR = 2.32; 95% CI, 1.47-3.68) or chronic obstructive pulmonary disease (OR = 1.55; 95% CI, 1.16-2.10). Living with other smokers was correlated with a lower chance of recycling into treatment (OR = 0.72; 95% CI, 0.57-0.91). Recycling previous quitline participants using a proactive, IVR-based intervention is effective in reinitiating quitline-assisted quit attempts. Older, long-term smokers reporting chronic conditions are more likely than younger smokers to re-engage in quitline support when these methods are used.

The Raman tensor of a crystal is the derivative of its polarizability tensor and is dependent on the symmetries of the crystal and the Raman-active vibrational mode. The intensity of a particular mode is determined by the Raman selection rule, which involves the Raman tensor and the polarization configurations. For anisotropic two-dimensional (2D) layered crystals, polarized Raman scattering has been used to reveal the crystalline orientations. However, due to its complicated Raman tensors and optical birefringence, the polarized Raman scattering of triclinic 2D crystals has not been well studied yet. Herein, we report the anomalous polarized Raman scattering of 2D layered triclinic rhenium disulfide (ReS 2 ) and show a large circular intensity differential (CID) of Raman scattering in ReS 2 of different thicknesses. The origin of CID and the anomalous behavior in polarized Raman scattering were attributed to the appearance of nonzero off-diagonal Raman tensor elements and the phase factor owing to optical birefringence. This can provide a method to identify the vertical orientation of triclinic layered materials. These findings may help to further understand the Raman scattering process in 2D materials of low symmetry and may indicate important applications in chiral recognition by using 2D materials.

The effect of hand position on perceived finger orientation in left- and right-handers.

Science.gov (United States)

Fraser, Lindsey E; Harris, Laurence R

2017-12-01

In the absence of visual feedback, the perceived orientation of the fingers is systematically biased. In right-handers these biases are asymmetrical between the left and right hands in the horizontal plane and may reflect common functional postures for the two hands. Here we compared finger orientation perception in right- and left-handed participants for both hands, across various hand positions in the horizontal plane. Participants rotated a white line on a screen optically superimposed over their hand to indicate the perceived position of the finger that was rotated to one of seven orientations with the hand either aligned with the body midline, aligned with the shoulder, or displaced by twice the shoulder-to-midline distance from the midline. We replicated the asymmetric pattern of biases previously reported in right-handed participants (left hand biased towards an orientation ~30° inward, right hand ~10° inward). However, no such asymmetry was found for left-handers, suggesting left-handers may use different strategies when mapping proprioception to body or space coordinates and/or have less specialization of function between the hands. Both groups' responses rotated further outward as distance of the hand from the body midline increased, consistent with other research showing spatial orientation estimates diverge outward in the periphery. Finally, for right-handers, precision of responses was best when the hand was aligned with the shoulder compared to the other two conditions. These results highlight the unique role of hand dominance and hand position in perception of finger orientation, and provide insight into the proprioceptive position sense of the upper limbs.

Ontologies and Formation Spaces for Conceptual ReDesign of Systems

Full Text Available This paper discusses ontologies, methods for developing them and languages for representing them. A special ontology for computational support of the Conceptual ReDesign Process (CRDP is introduced with a simple illustrative example of an application. The ontology denoted as Global context (GLB combines features of general semantic networks and features of UML language. The ontology is task-oriented and domain-oriented, and contains three basic strata – GLBExpl(stratum of Explanation, GLBFAct (stratum of Fields of Activities and GLBEnv (stratum of Environment, with their sub-strata. The ontology has been developed to represent functions of systems and their components in CRDP. The main difference between this ontology and ontologies which have been developed to identify functions (the semantic details in those ontologies must be as deep as possible is in the style of the description of the functions. In the proposed ontology, Formation Spaces were used as lower semantic categories the semantic deepness of which is variable and depends on the actual solution approach of a specialised Conceptual Designer.

In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known.We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM" patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase.

Origin of the OFF state variability in ReRAM cells

2014-01-01

This work exploits the switching dynamics of nanoscale resistive random access memory (ReRAM) cells with particular emphasis on the origin of the observed variability when cells are consecutively cycled/programmed at distinct memory states. It is demonstrated that this variance is a common feature of all ReRAM elements and is ascribed to the formation and rupture of conductive filaments that expand across the active core, independently of the material employed as the active switching core, the causal physical switching mechanism, the switching mode (bipolar/unipolar) or even the unit cells' dimensions. Our hypothesis is supported through both experimental and theoretical studies on TiO 2 and In 2 O 3  : SnO 2 (ITO) based ReRAM cells programmed at three distinct resistive states. Our prototypes employed TiO 2 or ITO active cores over 5 × 5 µm 2 and 100 × 100 µm 2 cell areas, with all tested devices demonstrating both unipolar and bipolar switching modalities. In the case of TiO 2 -based cells, the underlying switching mechanism is based on the non-uniform displacement of ionic species that foster the formation of conductive filaments. On the other hand, the resistive switching observed in the ITO-based devices is considered to be due to a phase change mechanism. The selected experimental parameters allowed us to demonstrate that the observed programming variance is a common feature of all ReRAM devices, proving that its origin is dependent upon randomly oriented local disorders within the active core that have a substantial impact on the overall state variance, particularly for high-resistive states.

Poor sleep quality affects spatial orientation in virtual environments

Directory of Open Access Journals (Sweden)

Silvana Valera

2016-07-01

Full Text Available Sleep is well known to have a significant impact on learning and memory. Specifically, studies adopting an experimentally induced sleep loss protocol in healthy individuals have provided evidence that the consolidation of spatial memories, as acquired through navigating and orienteering in spatial surroundings, is negatively affected by total sleep loss. Here, we used both objective and subjective measures to characterize individuals' quality of sleep, and grouped participants into either a poor (insomnia-like or normal (control sleep quality group. We asked participants to solve a wayfinding task in a virtual environment, and scored their performance by measuring the time spent to reach a target location and the number of wayfinding errors made while navigating. We found that participants with poor sleep quality were slower and more error-prone than controls in solving the task. These findings provide novel evidence that pre-existing sleep deficiencies in otherwise healthy individuals affects negatively the ability to learn novel routes, and suggest that sleep quality should be accounted for among healthy individuals performing experimental spatial orientation tasks in virtual environments.

Although registries can rapidly identify clinical study participants, it is unknown which follow up methods for recruiting are most effective. Our goal is to examine the efficacy of three communication strategies for recruiting and enrolling patients who were identified via a contact registry (i.e., registry linked to a consent to re-contact program). Patients who met the study criteria were identified via the contact registry and targeted for recruitment. In condition 1, patients established in the university hepatology specialty clinics were contacted one time via phone call by the study coordinator and asked to participate (C1). In condition 2, non-established specialty clinic patients were mailed an IRB-approved letter with study information and instructions for calling the study coordinator to participate (C2). Condition 2A included patients who called within two weeks of receiving the letter (C2A); condition 2B included patients who did not call after receiving the letter but were subsequently contacted via phone call. A registry identified 1,060 patients, of which 661were eligible and targeted for recruiting. All 37 patients were reached in C1 and 17 (45.9%) were recruited. Nineteen of the 624 patients in C2A were reached and 10 were recruited whereas 120 of the 605 patients in C2B were reached and 53 (8.7%) were recruited. Seventy patients enrolled with C2B being the most effective (total, cost) recruitment strategy ( n = 50) ( p recruiting.

2013-01-01

Sexual orientation was examined as a moderator in the relation between biological sex and interpersonal problems. Participants were 60 lesbians, 45 heterosexual women, 37 gay men, and 39 heterosexual men, who completed the Inventory of Interpersonal Problems-Circumplex. Sexual orientation was found to moderate one of the eight interpersonal problems under study. Heterosexual women scored significantly higher than lesbian women in Non-assertive. Although hypothesized, gay men did not differ from heterosexual men along the Dominant-Cold quadrant. Implications of these results are discussed.

Little information exists about the causal relationships of sport and exercise participation with goal orientations, perceived athletic competence and intrinsic motivation in physical education. A longitudinal study was conducted involving 882 Greek students who completed questionnaires on three occasions: 3 - 5 weeks into the academic year, 3 - 6 weeks before the end of the academic year, and 7 months later. The data were analysed using structural equation models, controlling for age. Task orientation and intrinsic motivation in physical education at the beginning of the academic year predicted sport and exercise participation 7 and 14 months later. Perceived athletic competence both at the beginning and end of the academic year predicted sport and exercise participation 7 and 14 months later, while ego orientation did not predict sport and exercise involvement at either time. Previous sport and exercise participation had positive effects on task orientation and perceived athletic competence 3 - 6 weeks before the end of the academic year and predicted all cognitive-affective constructs 7 months later. These results imply that the cultivation of task orientation, intrinsic motivation in physical education and perceived athletic competence will help to promote sport and exercise participation in adolescence.

A simple greedy algorithm for dynamic graph orientation

DEFF Research Database (Denmark)

Berglin, Edvin; Brodal, Gerth Stølting

2017-01-01

Graph orientations with low out-degree are one of several ways to efficiently store sparse graphs. If the graphs allow for insertion and deletion of edges, one may have to flip the orientation of some edges to prevent blowing up the maximum out-degree. We use arboricity as our sparsity measure....... With an immensely simple greedy algorithm, we get parametrized trade-off bounds between out-degree and worst case number of flips, which previously only existed for amortized number of flips. We match the previous best worst-case algorithm (in O(log n) flips) for general arboricity and beat it for either constant...... or super-logarithmic arboricity. We also match a previous best amortized result for at least logarithmic arboricity, and give the first results with worst-case O(1) and O(sqrt(log n)) flips nearly matching degree bounds to their respective amortized solutions....

2005-01-01

In the present study, we examined the impact of cultural value orientations (i.e., the personally oriented value of individualism, and the socially oriented values of collectivism, familism, romanticism, and spiritualism) on accommodation (i.e., voice and loyalty, rather than exit and neglect, responses to partners' anger or criticism) in heterosexual and gay relationships; and we examined the impact of internalized homophobia (i.e., attitudes toward self, other, and disclosure) on accommodation specifically in gay relationships. A total of 262 heterosexuals (102 men and 162 women) and 857 gays (474 men and 383 women) participated in the present study. Consistent with hypotheses, among heterosexuals and gays, socially oriented values were significantly and positively related to accommodation (whereas the personally oriented value of individualism was unrelated to accommodation); and among gays in particular, internalized homophobia was significantly and negatively related to accommodation. Implications for the study of heterosexual and gay relationships are discussed.

Full Text Available The aim of this study is to examine the problem solving skills of orienteering athletes in terms of different variables. 157 male and 43 female orienteering athletes, making a total of 200 athletes that joined the 3rd Level of Turkey Championship in 2015 have participated in this study which is in a survey model. The data collection tools were the Problem Solving Inventory and Personal Information Form that were formed by Heppner & Peterson (1982 and adapted into Turkish by Şahin, Şahin & Heppner (1993. In the data analysis, descriptive statics, anova, t test and Tukey test have been utilized. In the line with the findings, it has been determined that the difference between the total mean values (85.55+20.45 that the orienteering athletes got from the problem solving inventory and their age, marital status, sports age, the years of practice in orienteering sports, and the status of being national player is significant (p<0.05. It has been found that male orienteering athletes perform higher evaluating approach compared to the female athletes, and that as the age levels increase, the problem solving skill is affected more positively. Furthermore, it has been determined that the perceptions of the participants that have more experience and sports age in orienteering sports and that do orienteering sports at a national level are more positive in the matter of problem solving skills.

A major obstacle in the utilization of Mo thin films in flexible electronics is their brittle fracture behavior. Within this study, alloying with Re is explored as a potential strategy to improve the resistance to fracture. The sputter-deposited Mo 1-x Re x films (with 0 ≤ x ≤ 0.31) were characterized in terms of structural and mechanical properties, residual stresses as well as electrical resistivity. Their deformation behavior was assessed by straining 50 nm thin films on polyimide substrates in uniaxial tension, while monitoring crack initiation and propagation in situ by optical microscopy and electrical resistance measurements. A significant toughness enhancement occurs with increasing Re content for all body-centered cubic solid solution films (x ≤ 0.23). However, at higher Re concentrations (x > 0.23) the positive effect of Re is inhibited due to the formation of dual-phase films with the additional close packed A15 Mo 3 Re phase. The mechanisms responsible for the observed toughness behavior are discussed based on experimental observations and electronic structure calculations. Re gives rise to both increased plasticity and bond strengthening in these Mo-Re solid solutions.

Fraternal Birth Order, Handedness, and Sexual Orientation in a Chinese Population.

Xu, Yin; Zheng, Yong

2017-01-01

We examined the relationship between handedness, fraternal birth order, and sexual orientation in a Chinese population, and analyzed the influence of the components assessing sexual orientation and criteria classifying individuals as homosexual on this relationship. A large sample of heterosexual, bisexual, and homosexual men and women participated in a web-based survey. Our results showed that homosexual women are more likely to be non-right-handed than heterosexual women, regardless of how sexual orientation was defined, whereas bisexual women are more likely to be non-right-handed than heterosexual women when sexual orientation was assessed via sexual attraction and sexual identity. Bisexual men are more likely to be non-right-handed than heterosexual men when sexual orientation was assessed via sexual attraction. We found neither a fraternal birth-order effect nor an interaction between sibling sex ratio, handedness, and sexual orientation. The small number of siblings may be the reason why we could not replicate the fraternal birth-order effect in this Chinese population, which highlights the importance of cultural differences in the understanding of handedness, fraternal birth order, and sexual orientation.

Motivated prediction of future feelings: effects of negative mood and mood orientation on affective forecasts.

Science.gov (United States)

Buehler, Roger; McFarland, Cathy; Spyropoulos, Vassili; Lam, Kent C H

2007-09-01

This article examines the role of motivational factors in affective forecasting. The primary hypothesis was that people predict positive emotional reactions to future events when they are motivated to enhance their current feelings. Three experiments manipulated participants' moods (negative vs. neutral) and orientation toward their moods (reflective vs. ruminative) and then assessed the positivity of their affective predictions for future events. As hypothesized, when participants adopted a reflective orientation, and thus should have been motivated to engage in mood-regulation processes, they predicted more positive feelings in the negative than in the neutral mood condition. This pattern of mood-incongruent affective prediction was not exhibited when participants adopted a ruminative orientation. Additionally, within the negative mood condition, generating affective forecasts had a more positive emotional impact on reflectors than on ruminators. The findings suggest that affective predictions are sometimes driven by mood-regulatory motives.

Giving birth with rape in one's past: a qualitative study.

Rape is one of the most traumatizing violations a woman can be subjected to, and leads to extensive health problems, predominantly psychological ones. A large proportion of women develop a form of posttraumatic stress termed Rape Trauma Syndrome. A previous study by our research group has shown that women with a history of rape far more often had an operative delivery in their first birth and those who gave birth vaginally had second stages twice as long as women with no history of sexual assault. The aim of this study is to examine and illuminate how women previously subjected to rape experience giving birth for the first time and their advice on the kind of birth care they regard as good for women with a history of rape. A semi-structured interview with 10 women, who had been exposed to rape before their first childbirth. Data on the birth experience were analyzed by qualitative content analysis. The main theme was "being back in the rape" with two categories: "reactivation of the rape during labor," with subcategories "struggle," "surrender," and "escape" and "re-traumatization after birth," with the subcategories "objectified," "dirtied," and "alienated body." A rape trauma can be reactivated during the first childbirth regardless of mode of delivery. After birth, the women found themselves re-traumatized with the feeling of being dirtied, alienated, and reduced to just a body that another body is to come out of. Birth attendants should acknowledge that the common measures and procedures used during normal birth or cesarean section can contribute to a reactivation of the rape trauma. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

Anti-tobacco television advertisement campaigns may convey messages on smoking-related health consequences and create norms against giving cigarettes. Altogether, 156 and 112 slots of a television advertisement "Giving cigarettes is giving harm" were aired on Suzhou and Yizheng, respectively, over one month in 2010. Participants were recruited from 15 locations in Suzhou and 8 locations in Yizheng using a street intercept method. Overall 2306 residents aged 18-45 years completed questionnaires, including 1142 before the campaign and 1164 after, with respective response rates of 79.1% and 79.7%. Chi square tests were used to compare the difference between categorical variables. After the campaign, 36.0% of subjects recalled that they had seen the advertisement. Residents of Suzhou had a higher recall rate than those of Yizheng (47.6% vs. 20.6%, P advertisement were more likely not to give cigarettes in the future than those who reported not seeing the advertisement (38.7% vs. 27.5%, P advertisements helped change societal norms and improve health behavior. Continuous and adequate funding of anti-tobacco media campaigns targeted at different levels of the general population is needed, in conjunction with a comprehensive tobacco control effort.

The effects of ayahuasca ritual participation on gay and lesbian identity.

Cavnar, Clancy

2014-01-01

The practice of drinking ayahuasca-a psychoactive brew indigenous to the Amazon-has been investigated in several studies and shown to have positive long-term effects on mental states, and a particularly strong positive effect on perceptions of identity. This article discusses if these previous findings can be found in the experience of gay people, who are often taught by their culture and religion that their lifestyles, values, and sexual orientation are unacceptable. The qualitative study examined the interview responses of 17 self-identified gay and lesbian participants who had drunk ayahuasca in a ceremonial context within the past three years, regarding their self-perceptions and integration of group beliefs. Participants drank either in shamanic or Santo Daime ceremonies or, in the case of one participant, with an Afro-Brazilian group that used ayahuasca. Participants reported affirmation of their sexual orientation, and no participants reported negative effects on perception of identity. Additional positive effects in other areas of their lives, which they attributed to ayahuasca sessions, contributed to the overall positive outcomes that were reported by this group as a result of their ritual participation.

Differences in self-orientation (or "self-construal") may affect how the visual environment is attended, but the neural and cultural mechanisms that drive this remain unclear. Behavioral studies have demonstrated that people from Western backgrounds with predominant individualistic values are perceptually biased towards local-level information; whereas people from non-Western backgrounds that support collectivist values are preferentially focused on contextual and global-level information. In this study, we compared two groups differing in predominant individualistic (N = 15) vs collectivistic (N = 15) self-orientation. Participants completed a global/local perceptual conflict task whilst undergoing functional Magnetic Resonance Imaging (fMRI) scanning. When participants high in individualistic values attended to the global level (ignoring the local level), greater activity was observed in the frontoparietal and cingulo-opercular networks that underpin attentional control, compared to the match (congruent) baseline. Participants high in collectivistic values activated similar attentional control networks o only when directly compared with global processing. This suggests that global interference was stronger than local interference in the conflict task in the collectivistic group. Both groups showed increased activity in dorsolateral prefrontal regions involved in resolving perceptual conflict during heightened distractor interference. The findings suggest that self-orientation may play an important role in driving attention networks to facilitate interaction with the visual environment.

Full Text Available In history didactics the concept of historical consciousness has become an important theoretical framework in developing a meaningful history education. One significant aspect of historical consciousness is to give students a “usable past” to orient to possible futures. Previous research has shown that history is important when students think about the future but that their use of history in meaning-making is simplistic and based on present-day-thinking. Much research has focused on advancing students’ ability to use history in orientation to possible futures, but less attention has been focused on contemporary studies and its role in the process of orientation. By introducing a tentative concept, civic consciousness, the issue of students’ orientation is explored by studying students’ perspectives on democracy in past-present-future. The data consists of 142 narratives and reveals a pattern of normative stances, process orientation and action orientation. These aspects are considered to be important components of civic consciousness and these have implications for how social studies educators should address the challenges of preparing students for the future.

Due to developments of the health market, economic aspects of the health system are more relevant. In this upcoming market the patient is regarded as customer and the doctor as provider of medical services. Studies on customer orientation in the ambulant medicine lag behind this dynamic. An aim of the study is to comprehend the attitudes of the doctors referring to the customer orientation. In a second step the findings are discussed according to statements of health-care paticipants. Developments in role comprehension of doctor and patient are focused to gain results in scientific and practical applications. Guideline-supported, partly narrative interviews with n=9 gynaecologists and n=11 general practitioners in Freiburg/Germany are recorded, transcribed and reviewed in a qualitative analysis. The statements of the doctors show patient satisfaction has an incremental meaning sspecially regarding the sequence of patient relationship and economic management of the doctor's workplace. The doctor's role comprehension meets with a refusal of the role of salesman and the patient as customer. The method of interviews is suitable to gather empirical impressions of the doctors. The control sample is adequate, however a bias due to inhomogeneous thematic affinitiy and local social-demographics might be possible. The customer orientation has become an important factor in doctor-patient relationtships. The relevance of the doctor-patient conversation and the risk of misuse of the patient confidence are mentioned by the doctors. The doctor as paternalistic care provider gives way to the customer-focused service provider. The doctor's necessity of autonomyssss and dependency on patient satisfaction have potential for conflict. Intensive mention of customer orientation in medicine in the media emphasises its importance. Rational handling with the possibilities of individual health markets is a prospective challange. Further research could be established in all aspects of
