    To determine the usefulness of the R2* value in assessing the histopathological grade of glioma at magnetic resonance imaging and differentiating various brain tumours. Sixty-four patients with brain tumours underwent R2* mapping and diffusion-weighted imaging examinations. ANOVA was performed to analyse R2* values among four groups of glioma and among high-grade gliomas (grades III and IV), low-grade gliomas (grades I and II), meningiomas, and brain metastasis. Spearman's correlation coefficients were used to determine the relationships between the R2* values or apparent diffusion coefficient (ADC) and the histopathological grade of gliomas. R2* values of low- and high-grade gliomas were analysed with the receiver-operator characteristic curve. R2* values were significantly different among high-grade gliomas, low-grade gliomas, meningiomas, and brain metastasis, but not between grade I and grade II or between grade III and grade IV. The R2* value (18.73) of high-grade gliomas provided a very high sensitivity and specificity for differentiating low-grade gliomas. A strong correlation existed between the R2* value and the pathological grade of gliomas. R2* mapping is a useful sequence for determining grade of gliomas and in distinguishing benign from malignant tumours. R2* values are better than ADC for characterising gliomas. (orig.)

    To investigate the correlation between R2(*) value of enhanced T2 star-weighted angiography (ESWAN) sequence and primary hepatocellular carcinoma infiltration and tumor thrombus, and investigate the biological behavior of HCC. A total of 221 cases of patients' imaging data with MRI examination(including ESWAN sequence) diagnosed as primary HCC were retrospectively analyzed.All the patients were collected from January 2014 to September 2015 in the First Affiliated Hospital of Dalian Medical University.The differences of R2(*) values in different MR types of HCC were analyzed.All patients were divided into infiltration group and non-infiltration group, tumor thrombus group and non-tumor thrombus group, the R2(*) values of the paired groups were compared.The diagnostic efficiency of R2(*) in HCC infiltration and tumor thrombus were evaluated by ROC curve, and to find out the threshold values. The MR types of 221 patients included 90 cases of nodular type, 62 cases of massive type, 69 cases of diffuse type.70 patients had tumor thrombus.The R2(*) values of different MR types were (21.82±8.52), (24.17±8.84)and (34.45±11.73) Hz, respectively.There was no statistically significant difference between the nodular and the massive types (P=0.144), while the difference between the nodular and diffuse type, the massive and diffuse types were statistically significant(P=0.000). The R2(*) values of infiltration group and non-infiltration group were (34.45±11.73) and (22.78±8.70) Hz , the R2(*) values of tumor thrombus group and non-tumor thrombus group were (31.20±12.17) and (24.21±9.90) Hz, the difference also had statistically significant(t=7.397 and 4.534, P=0.000 and 0.000). The AUC of R2(*) values for infiltration and tumor thrombus were 0.804, 0.681. R2(*) ≥24.68 Hz was the threshold value to diagnose the infiltration and tumor thrombus. R2(*) value can be used as a MR non-enhancement quantitative index to evaluate the biological behavior of HCC.

    To evaluate the utility of MR R2*-mapping and the optimal time-point for assessing the response of pulmonary metastatic renal cell carcinoma (mRCC) to anti-angiogenic targeted therapy (aATT). The exploration-sample group and the validation-sample group consisted of 22 and 16 patients. The parameters of MR R2*-mapping, including the R2* value at each time-point (R2*{sub base}, R2*{sub 1cyc} and R2*{sub 2cyc}) and change between different time-points (R2*{sub (1cyc-base)/base}, R2*{sub (2cyc-base)/base} and R2*{sub (2cyc-1cyc)/1cyc}), were evaluated with a receiver-operating-characteristic analysis, and a cut-off value derived from the clinical outcome was applied to the Kaplan-Meier method to assess the value of R2* mapping and Response-Evaluation-Criteria in Solid Tumours (RECIST) during treatment evaluation. The inter-, intra-observer agreements and inter-scan consistency were excellent (p > 0.80). For the exploration-sample group, the areas under the curve for the parameters of MR R2* mapping were 0.55, 0.60, 0.83, 0.64, 0.88 and 0.83 for R2*{sub base}, R2*{sub 1cyc}, R2*{sub 2cyc}, R2*{sub (1cyc-base)/base}, R2*{sub (2cyc-base)/base} and R2*{sub (2cyc-1cyc)/1cyc.} For the validation-sample, R2*{sub (2cyc-base)/base} better predicted progression-free survival (p = 0.03) than RECIST and other R2* mapping parameters with a lower p value. Assessing aATT outcome based on changes in the R2* value between baseline and second treatment is more accurate than assessment at other time-points and assessment based on the RECIST. (orig.)

    Full Text Available This study aimed to identify the antecedents of value, satisfaction and worth of mouth (WOM for franchise and flagship store shoppers. The literature review and a in-depth interview with the flasgship store manager indicated that brand and product aspects, as well the store environment and services aspects influence value, satisfaction and WOM. Then, a structural model was adjusted and tested with data collected from a survey with 275 consumers. Findings indicate that WOM and satisfaction are mediated by hedonism and utilitarism. Brand and store aspects are determinants of hedonic value and store aspects are associated with utilitarism. In addiction, flagship shoppers are more satisfied and tend to recommend the brand more than franchise shoppers. 

  14. Is valuing positive emotion associated with life satisfaction?

    2014-08-01

    The experience of positive emotion is closely linked to subjective well-being. For this reason, campaigns aimed at promoting the value of positive emotion have become widespread. What is rarely considered are the cultural implications of this focus on happiness. Promoting positive emotions as important for "the good life" not only has implications for how individuals value these emotional states, but for how they believe others around them value these emotions also. Drawing on data from over 9,000 college students across 47 countries we examined whether individuals' life satisfaction is associated with living in contexts in which positive emotions are socially valued. The findings show that people report more life satisfaction in countries where positive emotions are highly valued and this is linked to an increased frequency of positive emotional experiences in these contexts. They also reveal, however, that increased life satisfaction in countries that place a premium on positive emotion is less evident for people who tend to experience less valued emotional states: people who experience many negative emotions, do not flourish to the same extent in these contexts. The findings demonstrate how the cultural value placed on certain emotion states may shape the relationship between emotional experiences and subjective well-being.

    Hospitals are experiencing an estimated 16.5% turnover rate of registered nurses costing from $44,380 - $63,400 per nurse-an estimated $4.21 to $6.02 million financial loss annually for hospitals in the United States of America. Attrition of all nurses is costly. Most past research has focused on the new graduate nurse with little focus on the mid-career nurse. Attrition of mid-career nurses is a loss for the profession now and into the future. The purpose of the study was to explore relationships of professional values orientation, career development, job satisfaction, and intent to stay in recently hired mid-career and early-career nurses in a large hospital system. A descriptive correlational study of personal and professional factors on job satisfaction and retention was conducted. Participants and research context: A convenience sample of nurses from a mid-sized hospital in a metropolitan area in the Southwestern United States was recruited via in-house email. Sixty-seven nurses met the eligibility criteria and completed survey documents. Ethical considerations: Institutional Review Board approval was obtained from both the university and hospital system. Findings indicated a strong correlation between professional values and career development and that both job satisfaction and career development correlated positively with retention. Newly hired mid-career nurses scored higher on job satisfaction and planned to remain in their jobs. This is important because their expertise and leadership are necessary to sustain the profession into the future. Nurse managers should be aware that when nurses perceive value conflicts, retention might be adversely affected. The practice environment stimulates nurses to consider whether to remain on the job or look for other opportunities.

    Full Text Available The servant leadership literature has a growing body of evidence pointing to the positive relationship between servant leadership and job satisfaction. Because many of these studies have focused on quantitative analyses of the subject, the present study brings a complementary qualitative perspective. This article presents the findings of a case study focused on the servant leadership practices of the McNeff family in their network of family-owned companies in Anoka, Minnesota. Using the six servant leadership themes developed by Laub, the study focused on interviews with the owners and survey results from employees. The researchers found that the servant leadership practices of the owners are contributing to the job satisfaction of the employees. In addition, the researchers found evidence to suggest that the theme of valuing people may have a disproportionately strong effect on the culture of a business or organization, and serve as the foundation on which other servant leadership behaviors may occur.

    To investigate how paraprofessional Community Nutrition Educators' (CNEs') perceptions of work context relate to job satisfaction and intention to leave the position. Cross-sectional statewide survey of program personnel. Expanded Food and Nutrition Education Program (EFNEP) sites (n = 32) serving low- income families in New York. CNEs delivering EFNEP (n = 115). CNE job satisfaction and intention to leave. Multivariate regression analysis predicting work attitudes from perceived work context, CNE personality traits, and characteristics of CNEs, supervisors, and programs. Despite low satisfaction with pay, overall job satisfaction was high and intention to leave was low. Satisfaction was positively related to CNEs' perceptions of program value, work relationships, and having a voice in relevant decisions (adjusted R(2) = 0.60). Intention to leave was negatively related to perceptions of program value and supervision and satisfaction with pay (adjusted R(2) = 0.36), but the latter relationship was found only among more educated CNEs. CNEs' satisfaction and intention to leave were strongly associated with perceptions of program value, work relationships, and consultative management. Intrinsically motivating work, often viewed as the domain of professionals, is critical for the morale and retention of paraprofessional nutrition educators.

    Objective: To evaluate the stability and repeatability of gradient-echo sampling of spin- echo (GESSE) sequence in measuring the R 2 ' value in volunteers, by comparison with traditional GRE sequence (T 2 * ]nap and T 2 map). Methods: Eight normal healthy volunteers were enrolled in this study and written informed consents were obtained from all subjects. MR scanning including sequences of GESSE, T 2 map and T 2 * map were performed in these subjects at resting status. The same protocol was repeated one day later. Raw data from GESSE sequence were transferred to PC to conduct postprocessing with the software built in house. R 2 ' map and OEF map were got consequently. To obtain quantitative R 2 ' and OEF values in the brain parenchyma, six ROIs were equally placed in the anterior, middle and posterior part of bilateral hemispheres. Both mean and standard deviation of R 2 ' and OEF were recorded. All images from T 2 * map and T 2 map were transferred to the Workstation for postprocessing. The ROIs were put at the same areas as those for GESSE sequence. R 2 ' is defined as R 2 ' = R 2 * - R 2 , R 2 * = 1/T 2 * . The R 2 ' value of GESSE sequence were compared with that of GRE sequence. Results: The mean R 2 ' values of GESSE at the first and second scan and those of the GRE were (4.21±0.92), (4.45±0.94) Hz and (7.37±1.47), (6.42±2.33) Hz respectively. The mean OEF values of GESSE at the first and second scan is 0.327±0.036 and 0.336± 0.035 respectively. The R 2 ' value and OEF value obtained from GESSE were not significantly different between the first and second scan (t=-0.83, -1.48, P>0.05). The R 2 ' value of first GRE imaging had significantly statistical difference from that of second GRE imaging (t=1.80, P 2 ' value of GESSE sequence was less than that of GRE sequence, and there was significantly statistical difference between them (t=1.71, P<0.05). Conclusion: The GESSE sequence has good stability and repeatability with promising clinical practicability

  6. MATERIALISTIC VALUES, SHOPPING, AND LIFE SATISFACTION IN ROMANIA

    Directory of Open Access Journals (Sweden)

    VALERIU FRUNZARU

    2015-11-01

    Full Text Available Numerous studies have shown that generally materialists are less happy than those lower in materialism. Several studies confirm that people who experience a lower level of life satisfaction are more interested in shopping; therefore materialism determines directly and indirectly (mediated by life satisfaction the desire of going shopping. There are only few studies that deal with this topic within Romanian consumers. The conceptual model proposed here was tested on a convenience sample of 390 Romanians. Using structural equation modelling, our findings confirm the hypothetical model only partially. Materialism leads to life dissatisfaction and shopping, but life dissatisfaction does not increase shopping. To the contrary, there is a positive relationship between life satisfaction and the desire for shopping. One possible explanation is that Romanians perceive materialism as a positive attitude. Anyway, nuances should be considered regarding the role of money and possession in bringing life satisfaction

    To correlate the R2* value obtained by iterative decomposition of water and fat with echo asymmetry and least-squares emission (IDEAL) with fibrotic focus (FF), microvessel density and hypoxic biomarker (HIF-1α) in breast carcinoma. Forty-two patients who were diagnosed with invasive ductal carcinoma (IDC) of the breast underwent breast MRI including IDEAL before surgery. The entire region of interest (ROI) was delineated on the R2* map, and average tumour R2* value was calculated for each ROI. Histological specimens were evaluated for the presence of FF, the microvessel density (the average microvessel density and the ratio of peripheral to central microvessel density), and the grading of HIF-1α. FF was identified in 47.6% (20/42) of IDCs. Average R2* value for IDC with FF (42.4±13.2 Hz) was significantly higher than that without FF (28.5±13.9 Hz) (P = 0.01). Spearman rank correlation suggested that the average R2* value correlated with the grade of HIF-1α and the ratio of peripheral to central microvessel density for IDCs (P < 0.001). Quantification of tumour R2* using IDEAL is associated with the presence of FF and the overexpression of HIF-1α, and may therefore be useful in predicting hypoxia of breast carcinoma. (orig.)

    To investigate the effect of some psychosocial variables on nurses' job satisfaction. Nurses' job satisfaction is one of the most important factors in determining individuals' intention to stay or leave a health-care organisation. Literature shows a predictive role of work climate, professional commitment and work values on job satisfaction, but their conjoint effect has rarely been considered. A cross-sectional questionnaire survey was adopted. Participants were hospital nurses and data were collected in 2011. Professional commitment and work climate positively predicted nurses' job satisfaction. The effect of intrinsic vs. extrinsic work value orientation on job satisfaction was completely mediated by professional commitment. Nurses' job satisfaction is influenced by both contextual and personal variables, in particular work climate and professional commitment. According to a more recent theoretical framework, work climate, work values and professional commitment interact with each other in determining nurses' job satisfaction. Nursing management must be careful to keep the context of work tuned to individuals' attitude and vice versa. Improving the work climate can have a positive effect on job satisfaction, but its effect may be enhanced by favouring strong professional commitment and by promoting intrinsic more than extrinsic work values. © 2013 John Wiley & Sons Ltd.

    Full Text Available The purpose of this paper is to explore the relationships among service quality features (responsiveness, assurance, and empathy, perceived value and customer satisfaction in the context of Malaysia. The empirical data are drawn from 102 members of an academic staff of a Malaysian public institution of higher learning using a survey questionnaire. The results indicate three important findings: firstly, the interaction between perceived value and responsiveness was not significantly correlated with customer satisfaction. Secondly, the interaction between perceived value and assurance also did not correlate significantly with customer satisfaction. Thirdly, the interaction between perceived value and empathy correlated significantly with customer satisfaction. Thus the results demonstrate that perceived value had increased the effect of empathy on customer satisfaction, but it had not increased the effect of responsiveness and assurance on customer satisfaction. In sum, this study confirms that perceived value act as a partial moderating variable in the service quality models of the organizational sample. In addition, implications and limitations of this study, as well as directions for future research are discussed.

    The professional values that are typically attributed to nursing managers influence the behaviors of staff nurses as well as of nursing managers. Therefore, the efficient planning and implementation of nursing services require that nursing managers raise their awareness of professional nursing values. This study aims to investigate the correlations between professional values, job satisfaction, and intent to leave the job and the institution. This descriptive and cross-sectional study was conducted on 216 nursing managers in nine different hospitals in Turkey. The data were collected using a personal information form, Nursing Professional Values Scale, Minnesota Job Satisfaction Questionnaire, and scales on intent to leave the job and the institution. Results indicate a positive correlation between the professional values of nurses and their job satisfaction and suggest a negative correlation between professional values and intent to leave the job and the institution. Furthermore, agency was found to be a determinant of job satisfaction. Strong professional values were found to increase job satisfaction and decrease the intent to leave the job and the institution.

    Personal values are defined as "desirable goals varying in importance that serve as guiding principles in people's lives," and have been shown to influence specialty choice and relate to practice satisfaction. We wished to examine further the relationship of personal values to practice satisfaction and also to a physician's willingness to care for the underserved. We also wished to study associations that might exist among personal values, practice satisfaction, and a variety of practice characteristics. We randomly surveyed a stratified probability sample of 1224 practicing family physicians about their personal values (using the Schwartz values questionnaire), practice satisfaction, practice location, breadth of practice, demographics, board certification status, teaching involvement, and the payor mix of the practice. Family physicians rated the benevolence (motivation to help those close to you) value type highest, and the ratings of the benevolence value type were positively associated with practice satisfaction (correlation coefficient = 0.14, P = .002). Those involved in teaching medical trainees were more satisfied than those who were not involved (P = .009). Some value-type ratings were found to be positively associated with caring for the underserved. Those whose practices consisted of more than 40% underserved (underserved defined as Medicare, Medicaid, and indigent populations) rated the tradition (motivation to maintain customs of traditional culture and religion) value type significantly higher (P = .02). Those whose practices consisted of more than 30% indigent care rated the universalism (motivation to enhance and protect the well-being of all people) value type significantly higher (P = .03). Family physicians who viewed benevolence as a guiding principle in their lives reported a higher level of professional satisfaction. Likewise, physicians involved in the teaching of medical trainees were more satisfied with their profession. Family physicians

    Although there is considerable evidence to support the direct effects of self-efficacy beliefs on academic achievement, very few studies have explored the motivational mechanism that mediates the self-efficacy-achievement relationship, and they are necessary to understand how and why self-efficacy affects students' academic achievement. Based on a socio-cognitive perspective of motivation, this study examines the relationships among academic self-efficacy, students' expectancy-value beliefs, teaching process satisfaction, and academic achievement. Its main aim is to identify some motivational-underlying processes through which students' academic self-efficacy affects student achievement and satisfaction. Student achievement and satisfaction are two of the most important learning outcomes, and are considered key indicators of education quality. The sample comprises 797 Spanish secondary education students from 36 educational settings and three schools. The scales that referred to self-efficacy and expectancy-value beliefs were administered at the beginning of the course, while student satisfaction and achievement were measured at the end of the course. The data analysis was conducted by structural equation modeling (SEM). The results revealed that students' expectancy-value beliefs (Subject value, Process expectancy, Achievement expectancy, Cost expectancy) played a mediator role between academic self-efficacy and the achievement/satisfaction relationship. These results provided empirical evidence to better understand the mechanism that mediates self-efficacy-achievement and efficacy-course satisfaction relationships. The implications of these findings for teaching and learning in secondary education are discussed.

    Full Text Available The purpose of this conducted study was to test the direct and indirect effects of internet banking quality and customer value to customer satisfaction. This study uses descriptive analysis and multiple regression analysis to examine these relationships. The study is based on a survey conducted with respondents who use internet banking in their day-to-day activities, and all questionnaire items are deemed valid and reliable. For data analysis, the descriptive analysis for the indicators, dimensions, and variables proved to be in a good category. Research findings and implications of the regression analysis show that internet banking quality and customer value had a greater direct impact on customer satisfaction, rather the partial relationships of these variables to satisfaction. In the partial relationships, customer value has a higher influence on customer satisfaction, than internet banking quality. As a research recommendation, banks should provide a more humanistic internet banking service for better consumer satisfaction. A major research limitation of the study is that it does not measure service quality of internet banking, and only focuses on customers of internet banking use of one single bank. The originality of this research relies on the insights of internet banking quality leading to customer satisfaction and increasing the value of a bank to its main target markets.

    This study aimed to describe the effect of nursing profession work-related values on job satisfaction among a sample of Iranian nurses. We used in-depth interviews with 30 nurses who worked in university-affiliated and public hospitals in Tehran, Iran. The results of thematic analysis of interviews are reported in four themes to present the participants' articulations in linking their work-related values to job satisfaction. The themes consist of values that "encourage tolerance," "enhance inner harmony," "reflect traditional commitment," "enhance unity," and are "centered around altruism and spiritual values." The most satisfied participants considered nursing a divine profession and a tool by which they could gain spiritual pleasure and satisfaction. Our findings highlight the potential role of nursing work-related values in reducing dissatisfaction with one's job. For the nursing profession, this may have implications in reducing job instability and turnover.

    Personal social values have been identified as important determinants of generalists' specialty choice. However, the personal values or "guiding principles" of generalist physicians have not been identified scientifically. To establish a benchmark, we measured the personal values of exemplary family physicians because they serve as role models for current and future physicians. We also explored the relationship between personal values and practice satisfaction. We obtained a list of 330 family physicians nominated for the American Academy of Family Physicians' (AAFP) Family Doctor of the Year award for the years 1988 through 1993. We asked them to complete the Schwartz Values Questionnaire, a 56-item instrument for measuring personal values. They also answered three questions concerning practice satisfaction. The return rate was 83%. The physicians' mean age was 63 years. They had been in practice an average of 34 years, 93% were male, and 52% practiced in rural areas. Honesty was rated as the most important of the 56 values, and social power as the least important. Of the 10 value types (groups of common values), the responding physicians rated "Benevolence" as most important and "Power" as least important. Practice satisfaction correlated positively with the Benevolence value type (r = .21, P = .001) and negatively with the Power value type (r = -.15, P = .023). Of the 10 value types, Benevolence was rated the most important and Power the least important by exemplary family physicians, and both value types also correlated, positively and negatively, respectively, with their practice satisfaction. These results have implications for the selection, training, and career satisfaction of generalist physicians.

    2009-07-01

    Full Text Available Compensation management literature highlights that income has three major features: salary, bonus and allowance. If the level and/or amount of income are distributed to employees based on proper rules this may increase pay satisfaction. More importantly, a thorough investigation in this area reveals that the effect of income distribution on pay satisfaction is not consistent if perceived value of money is present in organizations. The nature of this relationship is less emphasized in pay distribution literature. Therefore, this study was conducted to measure the effect of the perceived value of money and income distribution on pay satisfaction using 136 usable questionnaires gathered from employees who have worked in one city based local authority in Sabah, Malaysia (MSLAUTHORITY. Outcomes of hierarchical regression analysis showed that the interaction between perceived value of money and income distribution significantly correlated with pay satisfaction. This result confirms that perceived value of money does act as a moderating variable in the income distribution model of the organizational sample. In addition, discussion and implications of this study are elaborated.

  7. Measuring the value of nonwage employee benefits: building a model of the relation between benefit satisfaction and value.

    Science.gov (United States)

    Weathington, Bart L; Jones, Allan P

    2006-11-01

    Researchers have commonly assumed benefits that employees view as more valuable have a greater influence on their attitudes and behaviors. Researchers have used 2 common methods to measure benefit value: attaching a monetary value to benefits and using self-reports of benefit importance. The present authors propose that the 2 approaches are conceptually distinct and have different implications. They use a social exchange perspective to justify this distinction and integrate both approaches and benefit satisfaction into a more comprehensive model of benefit perception. Results suggest that both measures have practical applications depending on the nature of the exchange relationship between the organization and employees. However, this relationship depends on the specific benefit and on employee satisfaction with that benefit. Some benefits lend themselves to a monetary estimate, whereas others lend themselves more to a nonmonetary valuation.

    2014-07-01

    The purpose of this study was to examine the relationship of congruency of leadership support and value of patient outcomes between nurses and nurse managers and nurses' job satisfaction and turnover intent. Turnover most often has a negative effect on an organization. Leadership support and patient outcomes have been identified as important factors, but congruency has not been studied in great detail. This quantitative non-experimental study included registered nurses (92) and nurse managers (21) in five non-magnet hospitals in the United States. Value congruence on leadership support was correlated with job satisfaction: Satisfaction in Nursing Scale (SINs)-Workload Barriers (r = 0.327, Administrative Support r = 0.544 and Collegiality = 0.920, P congruence and leadership support (Leadership Practices Inventory, LPI) was negatively correlated with turnover intent (r = 0.317, P 0.05) was noted. Value congruence of leadership support is related to job satisfaction and may be a factor in turnover intent. Nurse Administrators can use these results to develop policies to address the turnover especially in the area of leadership support. © 2013 John Wiley & Sons Ltd.

    McFarland, Daniel C.; Ornstein, Katherine; Holcombe, Randall F.

    2016-01-01

    Background Hospital Value-Based Purchasing (HVBP) incentivizes quality performance based healthcare by linking payments directly to patient satisfaction scores obtained from Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys. Lower HCAHPS scores appear to cluster in heterogeneous population dense areas and could bias CMS reimbursement. Objective Assess nonrandom variation in patient satisfaction as determined by HCAHPS. Design Multivariate regression modeling was performed for individual dimensions of HCAHPS and aggregate scores. Standardized partial regression coefficients assessed strengths of predictors. Weighted Individual (hospital) Patient Satisfaction Adjusted Score (WIPSAS) utilized four highly predictive variables and hospitals were re-ranked accordingly. Setting 3,907 HVBP-participating hospitals. Patients 934,800 patient surveys, by most conservative estimate. Measurements 3,144 county demographics (U.S. Census), and HCAHPS. Results Hospital size and primary language (‘non-English speaking’) most strongly predicted unfavorable HCAHPS scores while education and white ethnicity most strongly predicted favorable HCAHPS scores. The average adjusted patient satisfaction scores calculated by WIPSAS approximated the national average of HCAHPS scores. However, WIPSAS changed hospital rankings by variable amounts depending on the strength of the predictive variables in the hospitals’ locations. Structural and demographic characteristics that predict lower scores were accounted for by WIPSAS that also improved rankings of many safety-net hospitals and academic medical centers in diverse areas. Conclusions Demographic and structural factors (e.g., hospital beds) predict patient satisfaction scores even after CMS adjustments. CMS should consider WIPSAS or a similar adjustment to account for the severity of patient satisfaction inequities that hospitals could strive to correct. PMID:25940305

    Full Text Available Numerous findings suggest that female preferences for certain features of male faces vary during the menstrual cycle. Similarly, changes during the cycle have also been found in women's commitment to a current relationship. Furthermore, from the perspective of securing benefits from extra-pair affairs, the differences between women with high vs. low mate value could be expected. In this study we have tried to connect these sets of findings: first, we explored differences between partnered and single women in their ratings of male facial attractiveness in different phases of the menstrual cycle; and second, their satisfaction with the current relationship in relation to the cycle phase and selfperceived mate value. Two groups of women (single vs. partnered rated the attractiveness of two sets of male faces (normal vs. symmetrical. Repeated measures ANOVA showed that women in a relationship gave higher ratings of attractiveness for both normal and symmetrical faces in the luteal phase compared to the early follicular phase of a cycle, while single women showed the opposite pattern. Analyses of satisfaction with their current relationship in relation to cycle phase and self-perceived mate value showed that women with higher mate value are generally more satisfied with their current partners, and show smaller differences in satisfaction in various phases of the cycle. The results are interpreted in terms of content-specificity of hormone mediated adaptive design.

    This study aimed to determine whether definable profiles existed in a cohort of nursing staff with regard to demographic characteristics, job satisfaction, acculturation, work environment, stress, cultural values and coping abilities. A survey was conducted in one hospital in Singapore from June to July 2012, and 814 full-time staff nurses completed a self-report questionnaire (89% response rate). Demographic characteristics, job satisfaction, acculturation, work environment, perceived stress, cultural values, ways of coping and intention to leave current workplace were assessed as outcomes. The two-step cluster analysis revealed three clusters. Nurses in cluster 1 (n = 222) had lower acculturation scores than nurses in cluster 3. Cluster 2 (n = 362) was a group of younger nurses who reported higher intention to leave (22.4%), stress level and job dissatisfaction than the other two clusters. Nurses in cluster 3 (n = 230) were mostly Singaporean and reported the lowest intention to leave (13.0%). Resources should be allocated to specifically address the needs of younger nurses and hopefully retain them in the profession. Management should focus their retention strategies on junior nurses and provide a work environment that helps to strengthen their intention to remain in nursing by increasing their job satisfaction. © 2014 Wiley Publishing Asia Pty Ltd.

  7. Job satisfaction and job values among beginning nurses: a questionnaire survey.

    Daehlen, Marianne

    2008-12-01

    Concepts such as the theory-practice gap and reality shock call attention to the challenges nurses experience in their professional lives. These challenges seem to be particularly acute in the transition from nursing school to work. Based on an assumption that the theories and skills taught in school are not directly applicable to nursing practice, beginning nurses may find that they are not prepared to do the work for which they have trained. Consequently, nurses may experience challenges to their work ideals, and their level of job satisfaction may decline. In addition, major life changes, such as buying a house/apartment, becoming a parent or getting married are likely to occur in the first year after graduation. Consequently, the emphasis on economic rewards may increase in the transition from school to work. To examine the relationship between work ideals, experiences of work and job satisfaction through a vital period in nurses' careers. To compare beginning nurses' job satisfaction, perceived job rewards and values with those of beginning doctors and teachers. Survey data were collected from two cohorts of students in several educational programs in Norway. The survey was repeated among the same respondents, as workers, 3 years after graduation. Almost 3000 students were originally invited to participate. The response rate in the surveys varied from 59% to 80%. Tabular analyses and linear regression models. The results indicate similarities in nurses', doctors' and teachers' preferences for work, but differences in what they obtain. In the transition from school to work, nurses increase their emphasis on high income and job security, and 3 years after graduating, nurses' emphasis on these two job values is higher than that of doctors and teachers. Nurses were fairly satisfied with their present job. In terms of level of job satisfaction and their preferences for work, the transition from school to work for nurses seems less dramatic than initially assumed.

    Full Text Available Investigations to determine whether program perceived value could influence program satisfaction, program card loyalty and store loyalty are critical to elucidate the roles and significance of the constructs and advancing management practice. Accordingly, in line with this research direction, this study aims to assess the effects of program perceived value offered by few leading retail superstores and departmental stores in Malaysia on its members’ loyalty towards the store. The data set utilized in this study has been obtained via quota sampling technique, where a sample of 153 retail loyalty programs’ members was analyzed. An integrative conceptual model was developed and tested using Structural Equation Modeling using AMOS program. The results exemplify that program perceived value is a strong driver of program satisfaction and program card loyalty. Unexpectedly, program perceived value is not a significant predictor of store loyalty but, it has an indirect effect on store loyalty mediated by program satisfaction. Continuous plea in marketing management is to make marketing instruments more efficient. In recent years introduction of customer relationship marketing instruments is strongly advocated, both in marketing theory and practice. Several researchers (e.g., Berry 1983; Berry and Parasuraman 1991; and Gronroos, 1994 have changed the focus of a marketing orientation from attracting short-term, discrete transactional customers to retaining long-lasting, intimate customer relationships. In fact Roberts, Varki, Brodie (2003, further suggested that it is best to describe relationship marketing as the formation of “bonds” between the company and the customer. Achieving an effective relationship in a consumer context is considered to be even more challenging than it is in a business-to-business context, given the generally more polygamous character of consumers as opposed to business customers (Keng and Ehrenberger 1984; Pressey and

  9. Social Networking Websites Usage and Life Satisfaction: A Study of Materialist Values Shared by Facebook Users

    Directory of Open Access Journals (Sweden)

    Valeriu Frunzaru

    2015-07-01

    Full Text Available This paper attempts to analyze how materialist values mediate the relationship between time spent on social networking websites (SNW and overall life satisfaction. Admittedly, younger generations spend more time on SNW compared to older generations, therefore we can anticipate that younger people are more affected by materialism and, consequently, less satisfied with their lives. The conceptual model proposed here was tested on a convenience sample of 390 Romanian adults. Using structural equation modeling, our findings validate the hypothesis that younger people spend more time on SNW; the SNW usage makes them more materialistic and, as a result, less satisfied with life. These findings raise ethical questions regarding the impact of SNW on overall life satisfaction. For example, Facebook, the most popular SNW in Romania, is a virtual social sphere where people become “friends”, give or receive “likes”, are “fans” of something or somebody, etc. Therefore, we argue that Facebook is a symbolical locus for quantitative manifestations of something intimate and private, like feelings or appreciations. Such materialist approach to friendship and relationships has a significant negative impact on life satisfaction.

    This study investigated the relationship between consumer value and customer satisfaction, seeking a better understanding of the motivations underlying "green product" purchases. Based on the influence of demographic factors, it further explores the moderation effects of buyers' socio-demographics on the link between value and satisfaction. Data were collected through a mail survey of American hybrid car buyers. Consumer value, satisfaction, and socio-demographic information were measured, and the proposed relationships among them were tested using hierarchical multiple regression analysis. This study's findings reveal that values (i.e., functional and social) significantly impact hybrid satisfaction and that the effects vary by sex and age. This research provides insight into the motivations of green product purchases by incorporating important consumer characteristics.

    MR-based correction for photon attenuation in PET/MRI remains challenging, particularly for neurological applications requiring quantitation of data. Existing methods are either not sufficiently accurate or are limited by the computation time required. The goal of this study was to develop an MR-based attenuation correction method that accurately separates bone tissue from air and provides continuous-valued attenuation coefficients for bone. PET/MRI and CT datasets were obtained from 98 subjects (mean age [±SD]: 66yrs [±9.8], 57 females) using an IRB-approved protocol and with informed consent. Subjects were injected with 352±29MBq of (18)F-Florbetapir tracer, and PET acquisitions were begun either immediately or 50min after injection. CT images of the head were acquired separately using a PET/CT system. Dual echo ultrashort echo-time (UTE) images and two-point Dixon images were acquired. Regions of air were segmented via a threshold of the voxel-wise multiplicative inverse of the UTE echo 1 image. Regions of bone were segmented via a threshold of the R2* image computed from the UTE echo 1 and UTE echo 2 images. Regions of fat and soft tissue were segmented using fat and water images decomposed from the Dixon images. Air, fat, and soft tissue were assigned linear attenuation coefficients (LACs) of 0, 0.092, and 0.1cm(-1), respectively. LACs for bone were derived from a regression analysis between corresponding R2* and CT values. PET images were reconstructed using the gold standard CT method and the proposed CAR-RiDR method. The RiDR segmentation method produces mean Dice coefficient±SD across subjects of 0.75±0.05 for bone and 0.60±0.08 for air. The CAR model for bone LACs greatly improves accuracy in estimating CT values (28.2%±3.0 mean error) compared to the use of a constant CT value (46.9%±5.8, punits. From our analysis, we conclude that the proposed method closely approaches (<3% error) the gold standard CT-scaled method in PET reconstruction accuracy

    Full Text Available . The purpose of this study was to describe how companies in pharmaceutical and biological sectors can ensure their position in different markets by relying on sustainable, competitive advantages, resulting from the use of a well-defined marketing model with particular emphasis on brand improvement. As competition becomes more intense among companies and phenomena such as global marketing grow in importance, domestic industries in each country become obliged to improve their competitive advantages in order to survive from a marketing perspective. Customer satisfaction is among factors which could lead to the success and profitability of a company. The present research examined the relationship between brand value and customer behavioral intention. Accordingly, 80 questionnaires were distributed among customers, selected through random sampling in Tehran, Iran. The obtained data were analyzed by SPSS. Based on descriptive statistics, two aspects of customer behavioral intention included “product introduction” and “repeat purchase”, while two aspects of brand equity were “brand awareness” and “product introduction”. The research findings showed that factors such as “brand awareness” and “brand loyalty” directly affect customer behavioral intention and satisfaction.

    Hung, Chung-Jye; Chang, Hsin Hsin; Eng, Cheng Joo; Wong, Kit Hong

    Previous research has evaluated technology-based service encounters (TBSEs) in the delivery of health care by assessing patient satisfaction. This study examined service quality and perceived value of TBSEs used in health organisations from the perspective of clinical staff, with staff technology readiness as a moderator. A quantitative survey was conducted in Taiwan, across private and public healthcare organisations. Results showed that TBSEs had a direct effect on service quality and perceived value, which in turn had a direct effect on staff satisfaction in using TBSEs. However, service quality had no effect on perceived value when moderated by technology readiness. Theoretical and managerial implications of these findings are discussed.

    Student satisfaction is a quality measure of increasing importance in undergraduate programs, including nursing programs. To date theories of student satisfaction have focused primarily on students' perceptions of the educational environment rather than their perceptions of learning. Understanding how students determine satisfaction with learning is necessary to facilitate student learning across a range of educational contexts and meet the expectations of diverse stakeholders. To understand undergraduate nursing students' satisfaction with learning. Constructivist grounded theory methodology was used to identify how nursing students determined satisfaction with learning. Two large, multi-campus, nursing schools in Australia. Seventeen demographically diverse undergraduate nursing students studying different stages of a three year program participated in the study. Twenty nine semi-structured interviews were conducted. Students were invited to describe situations where they had been satisfied or dissatisfied with their learning. A constructivist grounded theory approach was used to analyse the data. Students are satisfied with learning when they shape a valued learning journey that accommodates social contexts of self, university and nursing workplace. The theory has three phases. Phase 1 - orienting self to valued learning in the pedagogical landscape; phase 2 - engaging with valued learning experiences across diverse pedagogical terrain; and phase 3 - recognising valued achievement along the way. When students experience a valued learning journey they are satisfied with their learning. Student satisfaction with learning is unique to the individual, changes over time and maybe transient or sustained, mild or intense. Finding from the research indicate areas where nurse academics may facilitate satisfaction with learning in undergraduate nursing programs while mindful of the expectations of other stakeholders such as the university, nurse registering authorities

    2017-10-01

    Ideally, college majors should be chosen to achieve self-realization and correspond to self-concept. However, some students select a major based on extrinsic factors, rather than aptitude or interests, because of a lack of employment opportunities. If they have negative college experiences with an unsatisfactory major, they might not engage fully in their occupation following graduation. This study aimed to identify factors affecting specialty satisfaction in preclinical practice nursing-college students. A cross-sectional descriptive survey. A nonprobability convenience sample of 312 nursing-college students at colleges in Deajeon City, South Korea. The survey questionnaire was distributed to those who agreed to participate. Freshmen and sophomore nursing students (n=312). Participants were 312 students at colleges in Deajeon City. A structured questionnaire was used to collect data, which were analyzed using SPSS/WIN. Positive psychological capital and nursing professional values were positively correlated with specialty satisfaction. Significant predictors for specialty satisfaction included hope and optimism (as components of positive psychological capital), the roles of nursing service and originality of nursing (as nursing professional values), and aptitude/interests and job value (as motives for selecting a major). The findings suggested that nursing students' specialty satisfaction was partially linked to positive psychological capital and professional values. Therefore, the promotion of positive factors should be useful in enhancing specialty satisfaction in preclinical-practice nursing-college students. Copyright © 2017 Elsevier Ltd.

    In their daily teaching and classroom management, teachers inevitably communicate and represent values. The purpose of this study was to explore relations between teachers' perception of school level values represented by the goal structure of the school and value consonance (the degree to which they felt that they shared the prevailing norms and values at the school), teachers' feeling of belonging, emotional exhaustion, job satisfaction, and motivation to leave the teaching profession. The participants were 231 Norwegian teachers in elementary school and middle school. Data were analyzed by means of structural equation modeling (SEM). Teachers' perception of mastery goal structure was strongly and positively related to value consonance and negatively related to emotional exhaustion, whereas performance goal structure, in the SEM model, was not significantly related to these constructs. Furthermore, value consonance was positively related to teachers' feeling of belonging and job satisfaction, whereas emotional exhaustion was negatively associated with job satisfaction. Job satisfaction was the strongest predictor of motivation to leave the teaching profession. A practical implication of the study is that educational goals and values should be explicitly discussed and clarified, both by education authorities and at the school level.

    To investigate the psychometric properties and relationships of perceived service quality, perceived value and overall satisfaction for residents with respect to their long-term care institutions. The five-point Likert scale questionnaire administered through facetoface interviews. Fourteen long-term care institutions located in central and southern Taiwan stratified according to services and accommodation population. One hundred and eighty long-term institutional care residents. Perceived service quality (the SERVPERF model), perceived value and overall satisfaction (models based on the literature on perceived value and satisfaction). Student's t-test on institutional location shows a significant difference between overall satisfaction for central and southern institution long-term care recipients. The correlation test revealed that the higher a resident's level of education, the higher the scores for perceived value. The factor loading results of confirmation factor analysis show acceptable levels of reliability and index-of-model fits for perceived service, perceived value and overall satisfaction. In addition, the results suggest that an additional construct, a positive attitude (happiness of outlook) towards long-term care institutions, is also an important factor in residents' overall satisfaction. The primary goal of long-term institutional care policy in Taiwan, as in other countries, is to provide residents with practical, cost-effective but high-quality care. On the basis of the results of in-depth interviews with long-term institutional care residents, this study suggests long-term care institutions arrange more family visit days to increase the accessibility and interaction of family and residents and thereby increase the happiness of outlook of the residents. © 2012 John Wiley & Sons Ltd.

    Alejandro Orgambídez-Ramos

    2013-09-01

    Full Text Available Since workforces are ageing throughout Europe, interest in the role of age in the workplace is increasing. Older workers with high work centrality are more likely to negotiate a relational contract and express higher levels of job satisfaction than older workers with low work centrality (Armstrong-Stassen and Schlosser, 2008. This study examines the role of work centrality and valued work outcomes as antecedents of job satisfaction. A cross sectional study using questionnaires was conducted. The sample consisted of 203 Spanish employees (M age = 55.78, SD = 3.01. Hierarchical multiple regression analyses have revealed that job satisfaction was significantly predicted by needed income and work centrality. When work is not an important part of older workers’ lives, they will prefer extrinsic outcomes and will not invest in the relationship with their organization (Grant & Wade-Benzoni, 2009. Implications for research and theory are explored in the conclusion.

    2007-01-01

    This study tests a consumer behavioral model on Taiwanese adolescents and young adults engaging in online gaming. The major focus is on how these consumers transfer the value of their experiences and lifestyles to satisfaction, which may assist in the further exploration of the specific consumption behavior characteristics of adolescents and young adults, particularly with regard to their social functioning and deep-seated psychological needs. Using a two-stage sampling design process, data were collected on a total of 211 consumers, with the statistical analysis methods adopted for this study including a reliability test, confirmatory factor analysis, and LISREL analysis. Our results indicate that causal relationships hold in certain experiential value and lifestyle constructs. In particular, two experiential value constructs (social function, empathy and escapism) and two lifestyle constructs (pursuit of recreation and taste for life, reference group) play major roles that affect satisfaction among adolescents and young adults in online gaming in Taiwan.

  20. Demographic factors and hospital size predict patient satisfaction variance--implications for hospital value-based purchasing.

    Science.gov (United States)

    McFarland, Daniel C; Ornstein, Katherine A; Holcombe, Randall F

    2015-08-01

    Hospital Value-Based Purchasing (HVBP) incentivizes quality performance-based healthcare by linking payments directly to patient satisfaction scores obtained from Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys. Lower HCAHPS scores appear to cluster in heterogeneous population-dense areas and could bias Centers for Medicare & Medicaid Services (CMS) reimbursement. Assess nonrandom variation in patient satisfaction as determined by HCAHPS. Multivariate regression modeling was performed for individual dimensions of HCAHPS and aggregate scores. Standardized partial regression coefficients assessed strengths of predictors. Weighted Individual (hospital) Patient Satisfaction Adjusted Score (WIPSAS) utilized 4 highly predictive variables, and hospitals were reranked accordingly. A total of 3907 HVBP-participating hospitals. There were 934,800 patient surveys by the most conservative estimate. A total of 3144 county demographics (US Census) and HCAHPS surveys. Hospital size and primary language (non-English speaking) most strongly predicted unfavorable HCAHPS scores, whereas education and white ethnicity most strongly predicted favorable HCAHPS scores. The average adjusted patient satisfaction scores calculated by WIPSAS approximated the national average of HCAHPS scores. However, WIPSAS changed hospital rankings by variable amounts depending on the strength of the predictive variables in the hospitals' locations. Structural and demographic characteristics that predict lower scores were accounted for by WIPSAS that also improved rankings of many safety-net hospitals and academic medical centers in diverse areas. Demographic and structural factors (eg, hospital beds) predict patient satisfaction scores even after CMS adjustments. CMS should consider WIPSAS or a similar adjustment to account for the severity of patient satisfaction inequities that hospitals could strive to correct. © 2015 Society of Hospital Medicine.

  8. Safe dismantling of the SVAFO research reactors R2 and R2-0 in Sweden

    International Nuclear Information System (INIS)

    ARNOLD, Hans-Uwe; BROY, Yvonne; Dirk Schneider

    2017-01-01

    The R2 and R2-0 reactors were part of the Swedish government's research program on nuclear power from the early 1960's. Both reactors were shut down in 2005 following a decision by former operator Studsvik Nuclear AB. The decommissioning of the R2 and R2-0 reactors is divided into three phases. The first phase - awarded to AREVA - involved dismantling of the reactors and associated systems in the reactor pool, treatment of the disassembled components as well as draining, cleaning and emptying the pool. In the second phase, the pool structure itself will be dismantled, while removal of remaining reactor systems, treatment and disposal of materials and clean-up will be carried out in the third stage. The entire work is planned to be completed before the end of this decade. The paper describes the several steps of phase 1 - starting with the team building, followed by the dismantling operations and covers challenges encountered and lessons learned as well. The reactors consist of 5.400 kg aluminum, 6.000 kg stainless steel restraint structures as well as, connection elements of the mostly flanged components (1.000 kg). The most demanding - from a radiological point of view - was the R2-0 reactor that was limited to ∼ 1 m"3 construction volumes but with an extremely heterogeneous activation profile. Based on the calculated radiological entrance data and later sampling, nuclide vectors for both reactors depending on the real placement of the single component and on the material (aluminum and stainless steel) were created. Finally, for the highest activated component from R2 reactor, 85 Sv/h were measured. The dismantling principles - adopted on a safety point of view - were the following: The always protected base area of the ponds served as a flexible buffer area for waste components and packaging. Specific protections were also installed on the walls to protect them from mechanical stress which may occur during dismantling work. A specific work platform was

Policies can increase the benefit potential to society of basic biomedical research by offering various kinds of incentives to basic researchers. In this paper we argue that soft incentives or "nudges" are particularly promising. However, to be well designed, these incentives must take into account the motivations, goals and views of the basic scientists. In the paper we present the results of an investigation that involved more than 300 scientists at Harvard Medical School and affiliated institutes. The results of this study suggest that some soft incentives could be valuable tools to increase the transformative value of fundamental investigations without affecting the spirit of the basic research and scientists' work satisfaction. After discussing the findings, we discuss a few examples of nudges for basic researchers in the biomedical fields.

    Full Text Available This study aims to test a model linking destination image, perceived value, tourist satisfaction, and tourist loyalty. Based on a sample of 300 tourists travelling by car from the World Natural Heritage Site of Tianchi, China, a new model of destination image was explored and data were analysed using partial least squares structural equation modelling (PLS-SEM. The results show that perceived value and satisfaction are direct antecedents of destination loyalty. Above all, perceived value and tourist satisfaction mediate the relationship between destination image and loyalty. Finally, this study discusses the theoretical and management implications of the findings in order to boost the tourism industry in the context of car trips.

    This study was done to examine the effects of nurses' perception of servant leadership on leader effectiveness, satisfaction and promoting additional effort. The focus was the mediating effects of leader trust and value congruence. Data were collected from 361 RN-BSN students and nurses participating in nationally attended in-service training programs. Data were analyzed using descriptive statistics and structural analysis with SPSS 17.0 windows program and Amos 7.0. Direct effects of nurses' perception of servant leadership were negative, but mediating effects of trust and value congruency were positively correlated with leader effectiveness, satisfaction and additional effort, that is servant leadership should be effective through mediating factors. The study results indicate that if the middle managers of nurses can build leader trust and value congruency between nurses through servant leadership, leader effectiveness, satisfaction and additional effort on the part of the nurses could result in a positive change in the long term.

  18. A General Bayesian Network Approach to Analyzing Online Game Item Values and Its Influence on Consumer Satisfaction and Purchase Intention

    Science.gov (United States)

    Lee, Kun Chang; Park, Bong-Won

    Many online game users purchase game items with which to play free-to-play games. Because of a lack of research into which there is no specified framework for categorizing the values of game items, this study proposes four types of online game item values based on an analysis of literature regarding online game characteristics. It then proposes to investigate how online game users perceive satisfaction and purchase intention from the proposed four types of online game item values. Though regression analysis has been used frequently to answer this kind of research question, we propose a new approach, a General Bayesian Network (GBN), which can be performed in an understandable way without sacrificing predictive accuracy. Conventional techniques, such as regression analysis, do not provide significant explanation for this kind of problem because they are fixed to a linear structure and are limited in explaining why customers are likely to purchase game items and if they are satisfied with their purchases. In contrast, the proposed GBN provides a flexible underlying structure based on questionnaire survey data and offers robust decision support on this kind of research question by identifying its causal relationships. To illustrate the validity of GBN in solving the research question in this study, 327 valid questionnaires were analyzed using GBN with what-if and goal-seeking approaches. The experimental results were promising and meaningful in comparison with regression analysis results.

  19. Good mates retain us right: investigating the relationship between mate retention strategies, mate value, and relationship satisfaction.

    Mate retention strategies are an important tool in keeping a partner, and their use is determined by the mate value (MV) of the partner one is trying to keep. The type of strategy used is also dependent on one's own MV: mates of lower MV are more prone to exhibiting strategies that are cost-inflicting for their partners, whereas partner-benefiting strategies are used by mates of higher value. The type of strategies used affects relationship satisfaction (RS), and is also affected by the perceived difference in MVs. However, it is unclear how someone's perception of their partner's MV is related to that partner's behavior and their own RS. To this aim, we investigated the relationship between these variables on a sample of 178 couples. Our results showed that benefit-inducing strategies were used more by--and towards--partners of higher MV, and were positively connected with RS. Cost-inflicting strategies were more used by--and towards--partners of lower MV, and were negatively connected with RS. Less MV difference was positively correlated with RS and benefiting strategies, and negatively correlated with cost-inflicting strategies. It seems that good mates use strategies that benefit their partners, which, in turn, make them more valuable and, consequently, their partner more satisfied.

    Highlights: • MRI with R2* relaxometry is suitable to detect iron overload of the pancreas. • Pancreatic iron overload can be present in HFE associated hereditary hemochromatosis. • R2* relaxometry of the pancreas should then be performed when liver iron is present. • It can be omitted in cases with no sign of hepatic iron. - Abstract: Purpose: To evaluate pancreatic iron in patients with human hemochromatosis protein associated hereditary hemochromatosis (HHC) using R2* relaxometry. Materials and methods: 81 patients (58 male, 23 female; median age 49.5, range 10–81 years) with HHC were retrospectively studied. All underwent 1.5 T magnetic resonance imaging (MRI) of the abdomen. A fat-saturated multi-gradient echo sequence with 12 echoes (TR = 200 ms; TE-initial 0.99 ms; Delta-TE 1.41 ms; 12 echoes; flip-angle: 20°) was used for the R2* quantification of the liver and the pancreas. Parameter maps were analyzed using regions of interest (3 in the liver and 2 in the pancreas) and R2* values were correlated. Results: 59/81 patients had a liver R2* ≥ 70 1/s of which 10/59 patients had a pancreas R2* ≥ 50 1/s. No patient presented with a liver R2* < 70 1/s and pancreas R2* ≥ 50 1/s. All patients with pancreas R2* values ≥ 50 1/s had liver R2* values ≥ 70 1/s. ROC analysis resulted in a threshold of 209.4 1/s for liver R2* values to identify HFE positive patients with pancreas R2* values ≥ 50 1/s with a median specificity of 78.87% and a median sensitivity of 90%. Conclusion: In patients with HHC R2* relaxometry of the pancreas should be performed when liver iron overload is present and can be omitted in cases with no sign of hepatic iron.

In this regard, we investigated the 10-year outcome of partners from three different economic levels regarding the relationship between emotional intelligence (EI and marital satisfaction.The research was designed as a descriptive-correlative survey and data were analyzed using Pearson correlation test and stepwise regression.Participants were 159 couples (N = 318 who were randomly selected through clustered sampling. The questionnaires included: Bar-on Emotional Intelligence (1997 and Enrich Marital satisfaction (1989.The findings revealed that the average values of emotional intelligence (m = 333.1 and marital satisfaction (m = 300.77 were high in the under-rich region (p<0.05. Moreover, there was no significant relationship between interpersonal and marital satisfaction within the under-rich region. On average, emotional intelligence accounted for 40.8% of marital satisfaction within those three regions (p<0.01.The results of the regression analysis showed that general mood is the most effective factor changing marital satisfaction in the three studied regions (R2= 0.34, rich (R2= 0.42 and semi-rich (R2= 0.52 regions (p<0.01. The most influential factor changing marital satisfaction in the under-rich (R2= 0.28 region was found to be stress management (p<0.01.

    Full Text Available Switching cost highlights the way how companies create barriers to proactively prevent customer defection which directly and significantly affects customer loyalty and then companies’ performance. The purpose of this paper is to provide empirical evidences about the impact of switching cost on customer loyalty by examining its mediating and moderating effects on the relationships between service value, customer satisfaction and customer loyalty. Specially, two difference types of switching costs, positive one and negative one, are proposed and tested independently in order to provide more insights about their impacts. The data about switching costs and other constructs are collected from 261 retail banking customers, and analysed using structural equation modelling and moderated path analysis. It is found that positive switching costs increase customer loyalty by partly transforming the effect of service value and customer satisfaction into customer loyalty. While negative switching cost only mediates the service value-loyalty relationship. Moreover, only negative switching cost has significant moderating effect on the satisfaction-loyalty relationships. Finally, the analysis reveals that negative switching cost might also weaken good impacts from positive switching cost on satisfaction-loyalty relationships.

  10. R2 inflation in anisotropic universes

    Berkin, A.L.

    1990-01-01

    The evolution of Bianchi type-I and type-IX universes for a theory of gravity with an εR 2 term added to the usual Lagrangian is considered. As in the spatially flat Robertson-Walker case considered previously by others, inflation is found to occur. For any amount of initial anisotropy, the anisotropy decays quickly relative to the length of the inflationary epoch, and the amount of expansion is enhanced by the anisotropy. The exceptions are Bianchi type-IX universes near or at isotropy. In these cases a wide range of initial parameters causes the universe to recollapse, thus reducing the phase space in which inflation can occur. The diagonal metric is shown to be the most general form in the R 2 theory for both Bianchi type-I universes with a perfect fluid and vacuum Bianchi type-IX models

  11. R 2 inflation to probe non-perturbative quantum gravity

    2018-03-01

    It is natural to expect a consistent inflationary model of the very early Universe to be an effective theory of quantum gravity, at least at energies much less than the Planck one. For the moment, R + R 2, or shortly R 2, inflation is the most successful in accounting for the latest CMB data from the PLANCK satellite and other experiments. Moreover, recently it was shown to be ultra-violet (UV) complete via an embedding into an analytic infinite derivative (AID) non-local gravity. In this paper, we derive a most general theory of gravity that contributes to perturbed linear equations of motion around maximally symmetric space-times. We show that such a theory is quadratic in the Ricci scalar and the Weyl tensor with AID operators along with the Einstein-Hilbert term and possibly a cosmological constant. We explicitly demonstrate that introduction of the Ricci tensor squared term is redundant. Working in this quadratic AID gravity framework without a cosmological term we prove that for a specified class of space homogeneous space-times, a space of solutions to the equations of motion is identical to the space of backgrounds in a local R 2 model. We further compute the full second order perturbed action around any background belonging to that class. We proceed by extracting the key inflationary parameters of our model such as a spectral index ( n s ), a tensor-to-scalar ratio ( r) and a tensor tilt ( n t ). It appears that n s remains the same as in the local R 2 inflation in the leading slow-roll approximation, while r and n t get modified due to modification of the tensor power spectrum. This class of models allows for any value of r complete R 2 gravity a natural target for future CMB probes.

  12. Understanding the value of social networks in life satisfaction of elderly people: a comparative study of 16 European countries using SHARE data.

    2016-12-01

    Networks of family and friends are a source of support and are generally associated with higher life satisfaction values among older adults. On the other hand, older adults who are satisfied with their life may be more able to develop and maintain a wider social network. For this reason, the causal link between size and composition of the social networks and satisfaction with life is yet to be explored. This paper investigates the effect of the 'size', (number of family and friends, and network) and the 'composition' (the proportion of friends over total number of persons) of the social network on life satisfaction among older adults (50+). Moreover, we also investigate the patterns of this relation between different European countries. Data from the 4 th wave of Survey of Health, Ageing and Retirement in Europe and an instrumental variable approach are used to estimate the extent of the relation between life satisfaction and size and composition of social networks. Respondents in Western and Northern European (WNE) countries report larger networks than respondents in Eastern and Southern European (ESE) countries. However, the positive relationship between network size and life satisfaction is consistent across countries. On the other hand, the share of friends in the network appears to be generally negatively related to satisfaction with life, though results are not statistically significant for all countries. Apparently, a larger personal network is important for older adults (50+) to be more satisfied with life. Our results suggest that this relation is particularly positive if the network is comprised of family members.

    To evaluate pancreatic iron in patients with human hemochromatosis protein associated hereditary hemochromatosis (HHC) using R2* relaxometry. 81 patients (58 male, 23 female; median age 49.5, range 10-81 years) with HHC were retrospectively studied. All underwent 1.5T magnetic resonance imaging (MRI) of the abdomen. A fat-saturated multi-gradient echo sequence with 12 echoes (TR=200ms; TE-initial 0.99ms; Delta-TE 1.41ms; 12 echoes; flip-angle: 20°) was used for the R2* quantification of the liver and the pancreas. Parameter maps were analyzed using regions of interest (3 in the liver and 2 in the pancreas) and R2* values were correlated. 59/81 patients had a liver R2*≥70 1/s of which 10/59 patients had a pancreas R2*≥50 1/s. No patient presented with a liver R2*pancreas R2*≥50 1/s. All patients with pancreas R2* values≥50 1/s had liver R2* values≥70 1/s. ROC analysis resulted in a threshold of 209.4 1/s for liver R2* values to identify HFE positive patients with pancreas R2* values≥50 1/s with a median specificity of 78.87% and a median sensitivity of 90%. In patients with HHC R2* relaxometry of the pancreas should be performed when liver iron overload is present and can be omitted in cases with no sign of hepatic iron. Copyright © 2017 Elsevier B.V.

  5. R2 dark energy in the laboratory

    2018-05-01

    We analyze the role, on large cosmological scales and laboratory experiments, of the leading curvature squared contributions to the low-energy effective action of gravity. We argue for a natural relationship c0λ2≃1 at low energy between the R2 coefficients c0 of the Ricci scalar squared term in this expansion and the dark energy scale Λ =(λ MPl)4 in four-dimensional Planck mass units. We show how the compatibility between the acceleration of the expansion rate of the Universe, local tests of gravity and the quantum stability of the model all converge to select such a relationship up to a coefficient which should be determined experimentally. When embedding this low-energy theory of gravity into candidates for its ultraviolet completion, we find that the proposed relationship is guaranteed in string-inspired supergravity models with modulus stabilization and supersymmetry breaking leading to de Sitter compactifications. In this case, the scalar degree of freedom of R2 gravity is associated to a volume modulus. Once written in terms of a scalar-tensor theory, the effective theory corresponds to a massive scalar field coupled with the universal strength β =1 /√{6 } to the matter stress-energy tensor. When the relationship c0λ2≃1 is realized, we find that on astrophysical scales and in cosmology the scalar field is ultralocal and therefore no effect arises on such large scales. On the other hand, the scalar field mass is tightly constrained by the nonobservation of fifth forces in torsion pendulum experiments such as Eöt-Wash. It turns out that the observation of the dark energy scale in cosmology implies that the scalar field could be detectable by fifth-force experiments in the near future.

  6. Predictive value of age for coping: the role of self-efficacy, social support satisfaction and perceived stress.

    2009-05-01

    The present study was prompted by the lack of agreement on how coping changes with age. We postulate that the effect of age on coping is mediated by coping resources, such as self-efficacy, perceived stress and social support satisfaction. The participants in the study were community dwelling and aged between 22 and 88 years old. Data were collected using the General Self Efficacy Scale, the Social Support Questionnaire, the Perceived Stress Scale, the Geriatric Depression Scale, the Social Readjustment Rating Scale (life-events) and the Way of Coping Checklist. We performed path analyses for two competitive structural models: M1 (age does not directly affect coping processes) and M2 (age directly affects coping processes). Our results supported a modified version of M2. Age was not found to predict either of two coping strategies: problem-focused coping is predicted by self-efficacy and social support satisfaction; emotion-focused coping is predicted by social support satisfaction and perceived stress. Changes in coping over the lifespan reflect the effectiveness with which a person's adaptive processes deal with age-associated changes in self-referred beliefs and environment perception.

    Statisticians most often use the linear mixed model to analyze Gaussian longitudinal data. The value and familiarity of the R(2) statistic in the linear univariate model naturally creates great interest in extending it to the linear mixed model. We define and describe how to compute a model R(2) statistic for the linear mixed model by using only a single model. The proposed R(2) statistic measures multivariate association between the repeated outcomes and the fixed effects in the linear mixed model. The R(2) statistic arises as a 1-1 function of an appropriate F statistic for testing all fixed effects (except typically the intercept) in a full model. The statistic compares the full model with a null model with all fixed effects deleted (except typically the intercept) while retaining exactly the same covariance structure. Furthermore, the R(2) statistic leads immediately to a natural definition of a partial R(2) statistic. A mixed model in which ethnicity gives a very small p-value as a longitudinal predictor of blood pressure (BP) compellingly illustrates the value of the statistic. In sharp contrast to the extreme p-value, a very small R(2) , a measure of statistical and scientific importance, indicates that ethnicity has an almost negligible association with the repeated BP outcomes for the study.

    GUTIERAIM: The aim of this correlational study was to examine the relations between organizational commitment, perceived organizational support, work values, person-organization fit, developmental experiences, and global job satisfaction among nursing faculty. The global nursing shortage is well documented. At least 57 countries have reported critical shortages. The lack of faculty is finally being recognized as a major issue directly influencing the ability to admit and graduate adequate numbers of nurses. As efforts increase to both recruit and retain faculty, the concept of organizational commitment and what it means to them is important to consider. A cross-sectional correlational design was used. The present study investigated the underlying structure of various organizational factors using structural equation modelling. Data were collected from a stratified random sample of nurse faculty during the academic year 2006-2007. The final model demonstrated that perceived organizational support, developmental experiences, person-organization fit, and global job satisfaction positively predicted nurse faculty's organizational commitment to the academic organization. Cross-validation results indicated that the final full SEM is valid and reliable. Nursing faculty administrators able to use mentoring skills are well equipped to build positive relationships with nursing faculty, which in turn, can lead to increased organizational commitment, productivity, job satisfaction, and perceived organizational support, among others. © 2012 Blackwell Publishing Ltd.

    Let X : R 2 / D → R 2 be a differentiable vector field, where D is compact. If the eigenvalues of the jacobian matrix DX z are (nonzero) purely imaginary, for all z element of R 2 / D . Then, X + v has a center type performance at infinity, for some v element of R 2 . More precisely, X + v has a periodic trajectory Γ subset of R2/ D which is surrounding D such that in the unbounded component of (R 2 / D )/ Γ all the trajectories of X + v are nontrivial cycles. In the case of global vector fields Y : R 2R 2 with Y (0) = 0, we prove that such eigenvalue condition implies the topological equivalency of Y with the linear vector field (x, y) → (-y, x).

    Quality, patient safety and value are important topics for graduate medical education (GME). Spaced education delivers case-based content in a structured longitudinal experience. Use of spaced education to deliver quality and safety education in GME at an institutional level has not been previously evaluated. To implement a spaced education course in quality, safety and value; to assess learner satisfaction; and to describe trainee knowledge in these areas. We developed a case-based spaced education course addressing learning objectives related to quality, safety and value. This course was offered to residents and fellows about two-thirds into the academic year (March 2014) and new trainees during orientation (June 2014). We assessed learner satisfaction by reviewing the course completion rate and a postcourse survey, and trainee knowledge by the per cent of correct responses. The course was offered to 1950 trainees. A total of 305 (15.6%) enrolled in the course; 265/305 (86.9%) answered at least one question, and 106/305 (34.8%) completed the course. Fewer participants completed the March programme compared with the orientation programme (42/177 (23.7%) vs 64/128 (50.0%), peducation can help deliver and assess learners' understanding of quality, safety and value principles. Offering a voluntary course may result in low completion. Learners were satisfied with their experience and were introduced to new concepts. Published by the BMJ Publishing Group Limited.

  13. Renormalization group procedure for potential −g/r2

    2018-02-01

    Full Text Available Schrödinger equation with potential −g/r2 exhibits a limit cycle, described in the literature in a broad range of contexts using various regularizations of the singularity at r=0. Instead, we use the renormalization group transformation based on Gaussian elimination, from the Hamiltonian eigenvalue problem, of high momentum modes above a finite, floating cutoff scale. The procedure identifies a richer structure than the one we found in the literature. Namely, it directly yields an equation that determines the renormalized Hamiltonians as functions of the floating cutoff: solutions to this equation exhibit, in addition to the limit-cycle, also the asymptotic-freedom, triviality, and fixed-point behaviors, the latter in vicinity of infinitely many separate pairs of fixed points in different partial waves for different values of g.

  14. Does Fat Suppression via Chemically Selective Saturation (CHESS) Affect R2*-MRI for Transfusional Iron Overload Assessment? A Clinical Evaluation at 1.5 and 3 Tesla

    Purpose Fat suppression (FS) via chemically selective saturation (CHESS) eliminates fat-water oscillations in multi-echo gradient echo (mGRE) R2*-MRI. However, for increasing R2* values as seen with increasing liver iron content (LIC), the water signal spectrally overlaps with the CHESS band, which may alter R2*. Here, we investigate the effect of CHESS on R2* and describe a heuristic correction for the observed CHESS-induced R2* changes. Methods Eighty patients (49/31 female/male, mean age: 18.3±11.7 years) with iron overload were scanned with a non-FS and a CHESS-FS mGRE sequence at 1.5T and 3T. Mean liver R2* values were evaluated using 3 published fitting approaches. Measured and model-corrected R2* values were compared and statistically analyzed. Results At 1.5T, CHESS led to a systematic R2* reduction (PCHESS-induced R2* bias after correction (linear regression slopes: 1.032/0.927/0.981). No CHESS-induced R2* reductions were found at 3T. Conclusion The CHESS-induced R2* bias at 1.5T needs to be considered when applying R2*-LIC biopsy calibrations for clinical LIC assessment which were established without FS at 1.5T. The proposed model corrects the R2* bias and could therefore improve clinical iron overload assessment based on linear R2*-LIC calibrations. PMID:26308155

    To improve liver R2* mapping by incorporating adaptive neighborhood regularization into pixel-wise curve fitting. Magnetic resonance imaging R2* mapping remains challenging because of the serial images with low signal-to-noise ratio. In this study, we proposed to exploit the neighboring pixels as regularization terms and adaptively determine the regularization parameters according to the interpixel signal similarity. The proposed algorithm, called the pixel-wise curve fitting with adaptive neighborhood regularization (PCANR), was compared with the conventional nonlinear least squares (NLS) and nonlocal means filter-based NLS algorithms on simulated, phantom, and in vivo data. Visually, the PCANR algorithm generates R2* maps with significantly reduced noise and well-preserved tiny structures. Quantitatively, the PCANR algorithm produces R2* maps with lower root mean square errors at varying R2* values and signal-to-noise-ratio levels compared with the NLS and nonlocal means filter-based NLS algorithms. For the high R2* values under low signal-to-noise-ratio levels, the PCANR algorithm outperforms the NLS and nonlocal means filter-based NLS algorithms in the accuracy and precision, in terms of mean and standard deviation of R2* measurements in selected region of interests, respectively. The PCANR algorithm can reduce the effect of noise on liver R2* mapping, and the improved measurement precision will benefit the assessment of hepatic iron in clinical practice.

    R2R3-MYB transcription factors (TFs) have been shown to play important roles in plants, including in development and in various stress conditions. Phylogenetic analysis showed the presence of 249 R2R3-MYB TFs in Brassica napus, called BnaR2R3-MYB TFs, clustered into 38 clades. BnaR2R3-MYB TFs were distributed on 19 chromosomes of B. napus. Sixteen gene clusters were identified. BnaR2R3-MYB TFs were characterized by motif prediction, gene structure analysis, and gene ontology. Evolutionary analysis revealed that BnaR2R3-MYB TFs are mainly formed as a result of whole-genome duplication. Orthologs and paralogs of BnaR2R3-MYB TFs were identified in B. napus, B. rapa, B. oleracea, and Arabidopsis thaliana using synteny-based methods. Purifying selection was pervasive within R2R3-MYB TFs. K n /K s values lower than 0.3 indicated that BnaR2R3-MYB TFs are being functionally converged. The role of gene conversion in the formation of BnaR2R3-MYB TFs was significant. Cis-regulatory elements in the upstream regions of BnaR2R3-MYB genes, miRNA targeting BnaR2R3MYB TFs, and post translational modifications were identified. Digital expression data revealed that BnaR2R3-MYB genes were highly expressed in the roots and under high salinity treatment after 24 h. BnaMYB21, BnaMYB141, and BnaMYB148 have been suggested for improving salt-tolerant B. napus. BnaR2R3-MYB genes were mostly up regulated on the 14th day post inoculation with Leptosphaeria biglobosa and L. maculan. BnaMYB150 is a candidate for increased tolerance to Leptospheria in B. napus.

    Understanding patients' attitudes to their medical experience is essential for identifying value in the patient pathway, optimizing care and use of resources. This service evaluation was undertaken to determine patients' preferences and expectations for day case colonoscopy, a common gastrointestinal procedure for which there is limited such data. Patients attending for elective colonoscopy were invited to complete a composite, validated dedicated endoscopy questionnaire, with Likert-scale questions and a 15-point preference (ranking) scale of domains of endoscopy care that were considered most important (1) to least important (15) as contributing to a satisfactory experience. Two hundred and sixteen out of 224 patients returned questionnaires. Moderate to severe anxiety was recorded in 56% of patients, commonly with respect to anticipation of pain or the results of the procedure. The median values for ranked preference scores consistent with greatest importance for satisfaction were technical skill of the endoscopist (1), discomfort during the procedure (4), and manner of the endoscopist (5). Factors considered of relatively low importance included the single-sex environment (15) (although this was more important to female patients), noise levels (13), and explanation of delay (11). Only 14% of patients responded that they would be prepared to delay an appointment for a single-sex environment. Patients undergoing colonoscopy highly prioritize aspects of care relating to the interaction with the endoscopist and the procedure itself. Environment factors are considered to be less important. These findings may assist in service redesign around patient-identified value within the patient pathway.

  19. Scalaron from R2-gravity as a heavy field

    2018-05-01

    We study a model of inflation in which a scalar field χ is non-minimally coupled to Starobinsky's R2 gravity. After transforming it to the Einstein frame, a new scalar field, the scalaron phi, will appear and couple to χ with a nontrivial field metric, while χ acquires a positive mass via the non-minimal coupling. Initially inflation occurs along the phi direction with χ trapped near its origin by this induced mass. After phi crosses a critical value, it starts rolling down rapidly and proceeds to damped oscillations around an effective local minimum determined by the value of χ, while inflation still continues, driven by the χ field at this second stage where the effect of the non-minimal coupling becomes negligible. The presence of the damped oscillations during the transition from the first to second stage of inflation causes enhancement and oscillation features in the power spectrum of the curvature perturbation. Assuming that the oscillations may be treated perturbatively, we calculate these features by using the δ N formalism, and discuss its observational implications to large scale CMB anomalies or primordial black hole formation, depending on the scale of the features.

In this study, we construct quantum codes from cyclic codes over the ring R 2 , for arbitrary length n, with the restrictions μ 2 = 0, υ 2 = 0, w 2 = 0, μυ = υμ, μw = wμ, υw = wυ and μ (υw) = (μυ) w. Also, we give a necessary and sufficient condition for cyclic codes over R 2 that contains its dual. As a final point, we obtain the parameters of quantum error-correcting codes from cyclic codes over R 2 and we give an example of quantum error-correcting codes form cyclic codes over R 2 . (paper)

    We describe the fabrication of roll-to-roll (R2R) printed organic photovoltaic (OPV) modules using gravure printing and rotary screen-printing processes. These two-dimensional printing techniques are differentiating factors from coated OPVs enabling the direct patterning of arbitrarily shaped and sized features into visual shapes and, increasing the freedom to connect the cells in modules. The inverted OPV structures comprise five layers that are either printed or patterned in an R2R printing process. We examined the rheological properties of the inks used and their relationship with the printability, the compatibility between the processed inks, and the morphology of the R2R-printed layers. We also evaluate the dimensional accuracy of the printed pattern, which is an important consideration in designing arbitrarily-shaped OPV structures. The photoactive layer and top electrode exhibited excellent cross-dimensional accuracy corresponding to the designed width. The transparent electron transport layer extended 300 µm beyond the designed values, whereas the hole transport layer shrank 100 µm. We also examined the repeatability of the R2R fabrication process when the active area of the module varied from 32.2 cm2 to 96.5 cm2. A thorough layer-by-layer optimization of the R2R printing processes resulted in realization of R2R-printed 96.5 cm2 sized modules with a maximum power conversion efficiency of 2.1% (mean 1.8%) processed with high functionality.

    In the domain of mental health outcomes, increasing interest has been shown in complementing traditional symptom measures with measures of a patient's quality of life. The objective of this study was to evaluate the value of including the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) in the routine assessment battery used at a psychiatric hospital. The sample consisted of 1,276 consecutive inpatients treated at a private psychiatric hospital over a two-year period. Admission and discharge data were collected for the Q-LES-Q, the mental health subscales of the Medical Outcomes Short Form Questionnaire (SF-36), the Depression Anxiety Stress Scales, and the Health of the Nation Outcome Scale. Large patient improvements from admission to discharge were seen across all instruments (effect sizes from 0.8 to 1.5), including the Q-LES-Q (effect size 1.3). The Q-LES-Q correlated with existing symptom measures, and regression analyses revealed that quality of life predicted length of hospital stay even after symptoms of depression and anxiety were taken into account. Although the Q-LES-Q was correlated with symptom measures already in use, it added to the ability to predict patient length of stay, and showed some divergence from measures of clinical outcomes. This pattern was seen despite intentionally restricting the sample to patients with mood and affective disorder diagnoses. The value of considering quality of life in a comprehensive assessment of mental health outcomes is discussed.

    Objective: To investigate the effects of microwave exposure on motor learning and Glutamate receptor 2(GluR2) phosphorylation in rat cerebellum. Methods: The rabbits were trained for seven days to form eye-blink conditioning, and then divided randomly into control and microwave exposure group (at hours 0,3,24 and 72 subgroups after exposure, respectively). The rabbits were accepted 90 mW/cm 2 microwave exposure for 30 minutes, and the rectal temperature were detected immediately after exposure and specific absorption rate (SAR) value were calculated. Eye-blink conditioning were detected immediately after exposure, and cerebellar GluR2 protein and GluR2 phosphorylation were detected with Western blotting. Results: Rectal temperature of rabbits were increased by 3.02 degree C after exposure, and SAR value was 8.74 W/kg. The eye-blink conditioning decreased significantly after exposure, and cerebellar GluR2 protein expression had no significant alteration but phosphorylation reduced significantly after exposure. Conclusions: 90 mW/cm 2 microwave exposure has injurious effects on cerebellar GluR2 phosphorylation and motor learning. (authors)

    Serial surveillance of liver iron concentration (LIC) provides guidance for chelation therapy in patients with iron overload. The diagnosis of iron overload traditionally relies on core liver biopsy, which is limited by invasiveness, sampling error, cost and general poor acceptance by pediatric patients and parents. Thus noninvasive diagnostic methods such as MRI are highly attractive for quantification of liver iron concentration. To compare two MRI-based methods for liver iron quantification in children. 64 studies on 48 children and young adults (age range 4-21 years) were examined by gradient recalled echo (GRE) R2* and spin-echo R2 MRI at 1.5T to evaluate liver iron concentration. Scatter plots and Bland-Altman difference plots were generated to display and assess the relationship between the methods. With the protocols used in this investigation, Bland-Altman agreement between the methods is best when LIC is <20 mg/g dry tissue. Scatter plots show that all values with LIC <20 mg/g dry tissue fall within the 95% prediction limits. Liver iron concentration as determined by the R2* and R2 MR methods is statistically comparable, with no statistical difference between these methods for LIC <20 mg/g. (orig.)

    Full Text Available Objectives: This study aims to quantify the response of the transverse relaxation rate of the magnetic resonance (MR signal of the cerebral tissue in healthy volunteers to the administration of air with step-wise increasing percentage of oxygen. Materials and Methods: The transverse relaxation rate (R2FNx01 of the MR signal was quantified in seven volunteers under respiratory intake of normobaric gas mixtures containing 21, 50, 75, and 100% oxygen, respectively. End-tidal breath composition, arterial blood saturation (SaO 2 , and heart pulse rate were monitored during the challenge. R2FNx01 maps were computed from multi-echo, gradient-echo magnetic resonance imaging (MRI data, acquired at 3.0T. The average values in the segmented white matter (WM and gray matter (GM were tested by the analysis of variance (ANOVA, with Bonferroni post-hoc correction. The GM R2FNx01-reactivity to hyperoxia was modeled using the Hill′s equation. Results: Graded hyperoxia resulted in a progressive and significant (P < 0.05 decrease of the R2FNx01 in GM. Under normoxia the GM-R2FNx01 was 17.2 ± 1.1 s -1 . At 75% O 2 supply, the R2FNx01 had reached a saturation level, with 16.4 ± 0.7 s -1 (P = 0.02, without a significant further decrease for 100% O 2 . The R2FNx01-response of GM correlated positively with CO 2 partial pressure (R = 0.69 ± 0.19 and negatively with SaO 2 (R = -0.74 ± 0.17. The WM showed a similar progressive, but non-significant, decrease in the relaxation rates, with an increase in oxygen intake (P = 0.055. The Hill′s model predicted a maximum R2FNx01 response of the GM, of 3.5%, with half the maximum at 68% oxygen concentration. Conclusions: The GM-R2FNx01 responds to hyperoxia in a concentration-dependent manner, suggesting that monitoring and modeling of the R2FNx01-response may provide new oxygenation biomarkers for tumor therapy or assessment of cerebrovascular reactivity in patients.

    To compare the accuracy of R2CHADS2, CHADS2, and CHA2DS2-VASc scores vs the Society of Thoracic Surgeons (STS) score as predictors of morbidity and mortality after cardiovascular surgery. All patients who underwent cardiothoracic surgery at our institution from January 2008 to July 2013 were analyzed. Only those patients who fulfilled the criteria for STS score calculation were included. The R2CHADS2 score was computed as follows: 2 points for GFR < 60 mL/min/1.73 m(2) (R2), prior stroke or TIA (S2); 1 point for history of congestive heart failure (C), hypertension (H), age ≥75 years (A), or diabetes (D). Area under the curve (AUC) analysis was used to estimate the accuracy of the different scores. The end point variables included operative mortality, permanent stroke, and renal failure as defined by the STS database system. Of the 3,492 patients screened, 2,263 met the inclusion criteria. These included 1,160 (51%) isolated valve surgery, 859 (38%) coronary artery bypass graft surgery, and 245 (11%) combined procedures. There were 147 postoperative events: 75 (3%) patients had postoperative renal failure, 48 (2%) had operative mortality, and 24 (1%) had permanent stroke. AUC analysis revealed that STS, R2CHADS2, CHADS2, and CHA2DS2-VASc reliably estimated all postoperative outcomes. STS and R2CHADS2 scores had the best accuracy overall, with no significant difference in AUC values between them. The R2CHADS2 score estimates postoperative events with acceptable accuracy and if further validated may be used as a simple preoperative risk tool calculator. Copyright © 2016 Elsevier Inc.

    During LS1, the R2E project team will be working on a task as painstaking as it is crucial: to achieve a sixfold reduction in the number of electronic malfunctions caused by radiation. On their success depends the ability of the accelerator to function correctly at nominal energy. No mean challenge, considering it comes on top of the tenfold reduction already achieved since 2009.   The graph plots the rate of LHC beam dumps due to single-event effects against beam luminosity. An indication of the challenge that faces the R2E project teams during LS1! The origins of the project known as R2E (Radiation to Electronics) go back to 2007, when the CNGS (CERN Neutrinos to Gran Sasso) experiment was being commissioned. "Right from the outset, some CNGS control systems were causing problems. They would regularly break down in operations with beam," recalls Markus Brugger, head of the R2E project. "Even though the beam intensity was very low, we began to suspect that radiati...

  3. Radial Ultrashort TE Imaging Removes the Need for Breath-Holding in Hepatic Iron Overload Quantification by R2* MRI.

    2017-07-01

    The objective of this study is to evaluate radial free-breathing (FB) multiecho ultrashort TE (UTE) imaging as an alternative to Cartesian FB multiecho gradient-recalled echo (GRE) imaging for quantitative assessment of hepatic iron content (HIC) in sedated patients and subjects unable to perform breath-hold (BH) maneuvers. FB multiecho GRE imaging and FB multiecho UTE imaging were conducted for 46 test group patients with iron overload who could not complete BH maneuvers (38 patients were sedated, and eight were not sedated) and 16 control patients who could complete BH maneuvers. Control patients also underwent standard BH multiecho GRE imaging. Quantitative R2* maps were calculated, and mean liver R2* values and coefficients of variation (CVs) for different acquisitions and patient groups were compared using statistical analysis. FB multiecho GRE images displayed motion artifacts and significantly lower R2* values, compared with standard BH multiecho GRE images and FB multiecho UTE images in the control cohort and FB multiecho UTE images in the test cohort. In contrast, FB multiecho UTE images produced artifact-free R2* maps, and mean R2* values were not significantly different from those measured by BH multiecho GRE imaging. Motion artifacts on FB multiecho GRE images resulted in an R2* CV that was approximately twofold higher than the R2* CV from BH multiecho GRE imaging and FB multiecho UTE imaging. The R2* CV was relatively constant over the range of R2* values for FB multiecho UTE, but it increased with increases in R2* for FB multiecho GRE imaging, reflecting that motion artifacts had a stronger impact on R2* estimation with increasing iron burden. FB multiecho UTE imaging was less motion sensitive because of radial sampling, produced excellent image quality, and yielded accurate R2* estimates within the same acquisition time used for multiaveraged FB multiecho GRE imaging. Thus, FB multiecho UTE imaging is a viable alternative for accurate HIC assessment

    Purpose: To evaluate the correlations and relative contributions of components of a radiation oncology-specific patient satisfaction survey to their overall satisfaction scores. Methods and Materials: From September 2006 through August 2012, we prospectively collected data from 8069 patients receiving radiation treatments with a 26-question survey. Each question was rated on a 10-point Likert scale. We analyzed the correlation between scores for each question and the overall satisfaction question. We also dichotomized the scores to reflect satisfaction versus dissatisfaction and used logistic regression to assess the relationship between items in 4 domains (the patient–provider relationship, access and environmental issues, wait times, and educational information) and overall satisfaction. Results: Scores on all questions correlated with overall patient satisfaction scores (P 2 =0.4219), followed by wait times (R 2 =0.4000), access/environment (R 2 =0.3837), and patient education (R 2 =0.3700). The specific variables with the greatest effect on patient satisfaction were the care provided by radiation therapists (odds ratio 1.91) and pain management (odds ratio 1.29). Conclusions: We found that patients' judgment of provider relationships in an outpatient radiation oncology setting were the greatest contributors to their overall satisfaction ratings. Other measures typically associated with patient satisfaction (phone access, scheduling, and ease of the check-in process) correlated less strongly with overall satisfaction. These findings may be useful for other practices preparing to assess patient ratings of quality of care

  9. Shadow corrosion evaluation in the Studsvik R2 reactor

    International Nuclear Information System (INIS)

    Sanders, Ch.; Lysell, G.

    2000-01-01

    Post-irradiation examination has shown that increased corrosion occurs when zirconium alloys are in contact with or in proximity to other metallic objects. The observations indicate an influence of irradiation from the adjacent component as the enhanced corrosion occurs as a 'shadow' of the metallic object on the zirconium surface. This phenomenon could ultimately limit the lifetime of certain zirconium alloy components in the reactor. The Studsvik R2 materials test reactor has an In-Core Autoclave (INCA) test facility especially designed for water chemistry and materials research. The INCA facility has been evaluated and found suitable for shadow corrosion studies. The R2 reactor core containing the INCA facility was modeled with the Monte Carlo N-Particle (MCNP) code in order to evaluate the electron deposition in various materials and to develop a hypothesis of the shadow corrosion mechanism.

    In the United States, about 23 million people live within 6 meters of sea level. In many parts of the country, sea-level rise between 1960 and 2010 has already led to a 2-5-fold increase in the rate of `nuisance' flooding. On top of rising seas, intensifying hurricanes and more frequent extremes of heat, humidity and precipitation pose additional risks to coastal societies, economies and ecosystems. Addressing risks posed by changing climate conditions in coastal areas demands innovative strategies that intersect multiple disciplines including engineering, ecology, communication, climate science, and community planning. To be usable, it also requires engaging coastal stakeholders in the development of research questions, the assessment of implications of research for planning and policy, and the communication of research results. Yet traditional, disciplinary programs are poorly configured to train the workforce needed to assess coastal climate risk and to develop and deploy integrated strategies for increasing coastal climate resilience. Coastal Climate Risk & Resilience (C2R2) is an NSF Research Traineeship (NRT) working to prepare the workforce that will build coastal resilience in the face of climate risks. Through its trainee and certificate programs, C2R2 works with graduate students at Rutgers University from multiple disciplines to better integrate all the elements of coastal systems and to communicate effectively with coastal stakeholders. C2R2 students will acquire the knowledge and practical skills needed to become leading researchers and practitioners tackling the critical challenges of coastal resilience.

    Vukmir, Rade B

    2006-01-01

    This paper seeks to present an analysis of the literature examining objective information concerning the subject of customer service, as it applies to the current medical practice. Hopefully, this information will be synthesized to generate a cogent approach to correlate customer service with quality. Articles were obtained by an English language search of MEDLINE from January 1976 to July 2005. This computerized search was supplemented with literature from the author's personal collection of peer-reviewed articles on customer service in a medical setting. This information was presented in a qualitative fashion. There is a significant lack of objective data correlating customer service objectives, patient satisfaction and quality of care. Patients present predominantly for the convenience of emergency department care. Specifics of satisfaction are directed to the timing, and amount of "caring". Demographic correlates including symptom presentation, practice style, location and physician issues directly impact on satisfaction. It is most helpful to develop a productive plan for the "difficult patient", emphasizing communication and empathy. Profiling of the customer satisfaction experience is best accomplished by examining the specifics of satisfaction, nature of the ED patient, demographic profile, symptom presentation and physician interventions emphasizing communication--especially with the difficult patient. The current emergency medicine customer service dilemmas are a complex interaction of both patient and physician factors specifically targeting both efficiency and patient satisfaction. Awareness of these issues particular to the emergency patient can help to maximize efficiency, minimize subsequent medicolegal risk and improve patient care if a tailored management plan is formulated.

    of plant layout for proper scheduling of activities and form a robust basis for a D and D plan. The loss of expert knowledge between the time of plant shutdown and the beginning of D and D activities can be an obstacle to D and D efficiency. The WTR was shutdown for over 30 years between final shutdown and the beginning of D and D work. The obstacles can be reduced if: Plant drawings and records are updated during the operational phase of plant life so that such documents accurately reflect the condition of the plant at the time of final shutdown. In the case of WTR, drawings and records were segregated at the time of shutdown according to those records needed for D and D and those records that would not be needed. Unfortunately, plant staff confused the two groups of records and the records needed for D and D were discarded. If the reactor is associated with a large organization, a search of the organization for those with knowledge should be performed. The WTR D and D representatives indicated that if the records are up to date and of good quality, the need for personnel knowledge is diminished. Given the difference in labour rates between R2 and WTR, the work for an equivalent task at R2 would have to be performed about 30 to 40 percent more efficiently in order for the labour cost of the task to equal the WTR labour cost. The overall projected cost of the R2 D and D is MSEK 190.93 (2000 money values) compared to the WTR actual figure of MSEK 274.653 (1 USD approx. 10 SEK). The overall scale and composition of R2 is very similar to WTR, albeit with a smaller and lighter reactor vessel. With the major difference in labour rates, it is therefore somewhat surprising to find that the R2 estimate is approximately 30 per cent lower than the WTR actual cost. The adjusted project management WTR costs are just slightly more than the estimated project management costs for R2, whilst transport and disposal costs for WTR tend to be lower than for R2. Focus therefore turns to

    The use of a 4-bit digital-to-analog converter using two methods; Binary Weighted Resistors and R-2R Ladder is designed and presented in this paper. The main components that were used in constructing both circuits were different resistor values, operational amplifier (LM741) and single pole double throw switches. Both circuits were designed using MULTISIM software to be able to test the circuit for its ideal application and FRITZING software for the layout designing and fabrication to the printed circuit board. The implementation of both systems in an actual circuit benefits in determining and comparing the advantages and disadvantages of each. It was realized that the binary weighted circuit is more efficient DAC, having lower percentage error of 0.267% compared to R-2R ladder circuit which has a minimum of percentage error of 4.16%.

    R(2) effect-size measures are presented to assess variance accounted for in mediation models. The measures offer a means to evaluate both component paths and the overall mediated effect in mediation models. Statistical simulation results indicate acceptable bias across varying parameter and sample-size combinations. The measures are applied to a real-world example using data from a team-based health promotion program to improve the nutrition and exercise habits of firefighters. SAS and SPSS computer code are also provided for researchers to compute the measures in their own data.

    A pure gravity inflationary model for the Universe is examined which is based on adding an εR 2 term to the usual gravitational Lagrangian. The classical evolution is worked out, including eventual particle production and the subsequent join to radiation-dominated Friedmann behavior. We show that this model gives significant inflation essentially independent of initial conditions. The model has only one free parameter which is bounded from above by observational constraints on scalar and tensorial perturbations and from below by both the need for standard baryogenesis and the need for galaxy formation. This requires 10/sup 11/<ε/sup -1/2/<10/sup 13/ GeV

    This study aimed to (1) measure the degree of patient satisfaction among the clinical and nonclinical dental services offered at specialty dental centers and (2) investigate the factors associated with the degree of overall satisfaction. Four hundred and ninety-seven participants from five dental centers were recruited for this study. Each participant completed a self-administered questionnaire to measure patient satisfaction with clinical and nonclinical dental services. Analysis of variance, t-tests, a general linear model, and stepwise regression analysis was applied. The respondents were generally satisfied, but internal differences were observed. The exhibited highest satisfaction with the dentists' performance, followed by the dental assistants' services, and the lowest satisfaction with the center's physical appearance and accessibility. Females, participants with less than a bachelor's degree, and younger individuals were more satisfied with the clinical and nonclinical dental services. The stepwise regression analysis revealed that the coefficient of determination (R (2)) was 40.4%. The patient satisfaction with the performance of the dentists explained 42.6% of the overall satisfaction, whereas their satisfaction with the clinical setting explained 31.5% of the overall satisfaction. Additional improvements with regard to the accessibility and physical appearance of the dental centers are needed. In addition, interventions regarding accessibility, particularly when booking an appointment, are required.

    The effect of the pressure up to 1.4 GPa on the Curie temperature T c in the R 2 Fe 17 intermetallics with R = Nd, Er and Y was measured using a low field susceptibility technique. The identical character of the temperature dependence of susceptibility χ(T) of the R 2 Fe 17 intermetallics observed at ambient pressure (sharp step-like drop at T c ) is preserved at high pressures only in the case of Nd 2 Fe 17 . Pronounced broadening and splitting of the sharp drop of χ(T) was observed in Er 2 Fe 17 and Y 2 Fe 17 respectively. The initial pressure slopes of dTc/dp are large and negative for all studied compounds, having nearly the same values (dTc/dp = -36K/GPa for Nd 2 Fe 17 compound). The results are discussed from the point of view of the sensitivity of T c on the crystal structure, the number of nearest neighbors of Fe atoms and the possible effect of disordered structures in the R 2 Fe 17 intermetallics

    The level of the flux of hadrons with energy in the multi MeV range expected from the collimation system at Point 7 and from the collisions at the interaction Points 1, 5 and 8 will induce Single Event Errors (SEEs) of the standard electronics present in the equipment located around these Points. Such events would perturb LHC operation. As a consequence, within the framework of the R2E (Radiation to Electronics) Mitigation Project, the sensitive equipment will be shielded or relocated to safer areas. These mitigation activities will be performed mainly during Long Shutdown 1 (LS1). About 15 groups (including equipment owners) will be involved in these activities with work periods from a few days to several months. Some of them will have to work in parallel in several LHC points. This document presents these mitigation activities with their associated planning, organization process, and main concerns as identified today. (author)

    A discussion is presented of the different crystallographic forms that arise in the parent RM 5 (R rare earth including yttrium or thorium; M = Fe, Co or Ni) with CaCu 5 structure in which every third R is replaced by a pair of M. This results in the stoichiometric composition R 2 M 17 . Metallographic studies of well annealed and quenched specimens of CeFesub(x), HoFesub(x) and TmFesub(x) with x varying from 8 to 9.5 showed that only those with x = 8.5 consisted of one phase. Similar experiments with ThNisub(x) and YNisub(x), x varying from 6.5 to 8.5 revealed that in these cases, single phases were obtained with x = 7.5

    Full Text Available The purpose of this article is to investigate the effect of customer’s expectations and the perceived quality on customer’s loyalty with the mediating role of the perceived value and customer’s satisfaction. The statistic population of the article includes the customers of the agencies of Iran Khodro Company in Gilan province, the city of Rasht and due to the infinity of statistic population, the sample volume has been considered from the amount of 384, based on the Morgan table. After the collection of questionnaires, data has been analyzed by means of LISREL Software. The analysis of findings indicates that customer’s expectations of the products of Iran Khodro Company affected the perceived quality of the product as well as customer’s satisfaction positively and meaningfully. The research results have also indicated that the perceived quality of the products of Iran Khodro Company also has affected the perceived value of the product and the customer’s satisfaction, which has been representative of customer’s loyalty. In the area of customer’s perceptions of the quality of hardware, managers must pay more attention to beauty and charm of the surroundings and try to provide enough explanation and necessary response to customer’s questions about the selected automobiles. It is suggested to managers that by means of improving one of the dimensions of quality, they also improve customer’s perceptions and requests in other dimensions. Planning is necessary and required in order to improve the local space of agencies, improving the quality, and decreasing components prices. Planning for decreasing final price and supplying components with lower prices will be important.

  10. Microstructure in Zircaloy Creep Tested in the R2 Reactor

    2004-12-01

    Tubular specimens of Zircaloy-4 have been creep tested in bending in the R2 reactor in Studsvik. The creep deformation in the reactor core is accelerated in comparison with creep deformation outside the reactor core. The possible mechanisms behind this behaviour are described briefly. In order to determine which the actual mechanism is, the microstructure of the material creep tested in the R2 reactor has been examined by transmission electron microscopy. Due to the bending, material subjected to both tensile and compressive stress during creep was available. Since some of the proposed mechanisms might give microstructures which are different when the material is subjected to compressive or tensile stress it was assumed that examination of both types of material would give valuable information with regard to the operating mechanism. The result of the examination was that in the as-irradiated condition there were no obvious differences detected between materials which had been deformed in tension or compression. After a heat treatment to coarsen the irradiation induced microstructure there were still no significant differences between the two types of material. However it was now observed that in addition to dislocation loops the microstructure also contained network dislocations which presumably had been invisible in the electron microscope before heat treatment due to the high density of small dislocation loops in this state. It is therefore concluded that the most probable mechanism for irradiation creep in this case is climb and glide of the network dislocations. The role of irradiation is two-fold: It accelerates climb due to the production of point defects of which more interstitials than vacancies arrive to the network dislocations stopped at an obstacles. This leads to a net climb after which a dislocation is released from the obstacle and an amount of glide takes place. The second effect is the production of loops which serve as an increasing density of

  11. The R + var-epsilon R2 cosmology

    1988-01-01

    This thesis presents the study of a model cosmology based on the R + var-epsilon R 2 gravitational Lagrangian. It may be roughly divided into two distinct parts. First, the classical inflationary scenario is developed. Then, the formalism of quantum cosmology is employed to determined initial conditions for the classical model. In the work on the classical model, the evolution equations for an isotropic and homogeneous universe are solved to exhibit both early-time inflation and a smooth transition to subsequent radiation-dominated behavior. Then perturbations on this isotropic background are evolved through the model to provide constraints on the model parameters from the observational limits on anisotropy today. In the work on the wave function, the two boundary conditions of Vilenkin and Hartle and Hawking are compared. The wave functions obtained are restricted to the initial edge of classical Lorentzian inflationary trajectories as distributions over initial conditions for the classical inflationary model. It is found that Vilenkin's wave function prefers the universe to undergo a great deal of inflation, whereas Hartle and Hawking's wave function prefers the universe to undergo little inflation. Finally, both boundary conditions are shown to require the inhomogeneous perturbative modes start out in their ground states

    The lack of rural nursing studies makes it impossible to know whether rural and urban nurses perceive personal and organizational factors of job satisfaction similarly. Few reports of rural nurse job satisfaction are available. Since the unprecedented shortage of qualified rural nurses requires a greater understanding of what factors are important to retention, studies are needed. An analysis of the literature indicates job satisfaction is studied as both an independent and dependent variable. In this study, the concept is used to examine the intention to remain employed by measuring individual and organizational characteristics; thus, job satisfaction is used as a dependent variable. One hundred and three rural hospital nurses, from hospitals throughout the Northwest region of the United States were recruited for the study. Only nurses employed for more than one year were accepted. The sample completed surveys online. The McCloskey/Mueller Satisfaction Scale, the Gerber Control Over Practice Scale, and two open-ended job satisfaction questions were completed. The qualitative analysis of the open-ended questions identified themes which were then used to support the quantitative findings. Overall alphas were 0.89 for the McCloskey/Mueller Scale and 0.96 for the Gerber Control Over Practice Scale. Rural nurses indicate a preference for rural lifestyles and the incorporation of rural values in organizational practices. Nurses preferred the generalist role with its job variability, and patient variety. Most participants intended to remain employed. The majority of nurses planning to leave employment were unmarried, without children at home, and stated no preference for a rural lifestyle. The least overall satisfied nurses in the sample were employed from 1 to 3 years. Several new findings inform the literature while others support previous workforce studies. Data suggest some job satisfaction elements can be altered by addressing organizational characteristics and by

  13. Interleaved quantitative BOLD: Combining extravascular R2' - and intravascular R2-measurements for estimation of deoxygenated blood volume and hemoglobin oxygen saturation.

    Quantitative BOLD (qBOLD), a non-invasive MRI method for assessment of hemodynamic and metabolic properties of the brain in the baseline state, provides spatial maps of deoxygenated blood volume fraction (DBV) and hemoglobin oxygen saturation (HbO 2 ) by means of an analytical model for the temporal evolution of free-induction-decay signals in the extravascular compartment. However, mutual coupling between DBV and HbO 2 in the signal model results in considerable estimation uncertainty precluding achievement of a unique set of solutions. To address this problem, we developed an interleaved qBOLD method (iqBOLD) that combines extravascular R 2 ' and intravascular R 2 mapping techniques so as to obtain prior knowledge for the two unknown parameters. To achieve these goals, asymmetric spin echo and velocity-selective spin-labeling (VSSL) modules were interleaved in a single pulse sequence. Prior to VSSL, arterial blood and CSF signals were suppressed to produce reliable estimates for cerebral venous blood volume fraction (CBV v ) as well as venous blood R 2 (to yield HbO 2 ). Parameter maps derived from the VSSL module were employed to initialize DBV and HbO 2 in the qBOLD processing. Numerical simulations and in vivo experiments at 3 T were performed to evaluate the performance of iqBOLD in comparison to the parent qBOLD method. Data obtained in eight healthy subjects yielded plausible values averaging 60.1 ± 3.3% for HbO 2 and 3.1 ± 0.5 and 2.0 ± 0.4% for DBV in gray and white matter, respectively. Furthermore, the results show that prior estimates of CBV v and HbO 2 from the VSSL component enhance the solution stability in the qBOLD processing, and thus suggest the feasibility of iqBOLD as a promising alternative to the conventional technique for quantifying neurometabolic parameters.

    The measurement of patient satisfaction is now an integral part of hospital market research. Just as consumer satisfaction is a function of the extent to which providers do things right, the value of consumer-oriented market research is directly related to whether the research itself is done right. The use of poorly designed consumer research instruments, no matter how well executed, can cause multicollinearity among the independent variables, which, in turn, can result in misleading conclusions.

  15. Spectroscopic studies of the iron and manganese reconstituted tyrosyl radical in Bacillus cereus ribonucleotide reductase R2 protein.

    Ane B Tomter

    Full Text Available Ribonucleotide reductase (RNR catalyzes the rate limiting step in DNA synthesis where ribonucleotides are reduced to the corresponding deoxyribonucleotides. Class Ib RNRs consist of two homodimeric subunits: R1E, which houses the active site; and R2F, which contains a metallo cofactor and a tyrosyl radical that initiates the ribonucleotide reduction reaction. We studied the R2F subunit of B. cereus reconstituted with iron or alternatively with manganese ions, then subsequently reacted with molecular oxygen to generate two tyrosyl-radicals. The two similar X-band EPR spectra did not change significantly over 4 to 50 K. From the 285 GHz EPR spectrum of the iron form, a g(1-value of 2.0090 for the tyrosyl radical was extracted. This g(1-value is similar to that observed in class Ia E. coli R2 and class Ib R2Fs with iron-oxygen cluster, suggesting the absence of hydrogen bond to the phenoxyl group. This was confirmed by resonance Raman spectroscopy, where the stretching vibration associated to the radical (C-O, ν(7a = 1500 cm(-1 was found to be insensitive to deuterium-oxide exchange. Additionally, the (18O-sensitive Fe-O-Fe symmetric stretching (483 cm(-1 of the metallo-cofactor was also insensitive to deuterium-oxide exchange indicating no hydrogen bonding to the di-iron-oxygen cluster, and thus, different from mouse R2 with a hydrogen bonded cluster. The HF-EPR spectrum of the manganese reconstituted RNR R2F gave a g(1-value of ∼2.0094. The tyrosyl radical microwave power saturation behavior of the iron-oxygen cluster form was as observed in class Ia R2, with diamagnetic di-ferric cluster ground state, while the properties of the manganese reconstituted form indicated a magnetic ground state of the manganese-cluster. The recent activity measurements (Crona et al., (2011 J Biol Chem 286: 33053-33060 indicates that both the manganese and iron reconstituted RNR R2F could be functional. The manganese form might be very important, as it has 8

    In Sweden the national fundamental values for care of older people state that care should ensure that they can live in dignity and with a sense of well-being. Our hypothesis was that a caregiver intervention targeting the national fundamental values would improve perceived empowerment, person-centered climate and life satisfaction among older people living in residential facilities. The study was a cluster-randomized controlled trial with a pre- and one post-test design, conducted in 27 units (17 study units) at 12 residential facilities for older people in five municipalities in central Sweden. The units in each municipality were randomly assigned to intervention or control group. The caregiver intervention was carried out using an interpretative approach with eight guided face-to-face seminars, where self-reflection and dialogue were used. Data were collected using questionnaires. The number of residents was 43 (78 %) in the intervention group and 37 (71 %) in the control group. The Chi-square test and Mann-Whitney U-tests were performed to detect differences between groups and Wilcoxon signed rank tests to explore differences in change over time within groups. Furthermore, generalized estimating equation (GEE) models were used to study effects of the intervention controlling for clustering effects. Primary outcome measures were empowerment, person-centered climate and life satisfaction. In the intervention group, improvements at follow-up were found in residents' self-reported empowerment (n = 42; p = 0.001, Median difference 4.0, 95 % CI 1.5;6.0), person-centered climate (n = 42; p ≤0.001, Median difference 8.0, 95 % CI 4.5;11.4) and life satisfaction regarding the factor quality of everyday activities (n = 40; p = 0.033, Median difference 9.7, 95 % CI 1.0;21.9) while disempowerment decreased (n = 43; p = 0.018, Median difference -1.3, 95 % CI -2.0;0.0). In the control group person-centered climate decreased (n = 37; p

    Clinical research professionals are faced with decreased funding and increased workloads; innovative methods of professional development programs are necessary to accommodate these factors. This study evaluated the feasibility, perceived satisfaction, and value of using webinars to educate clinical research professionals on reporting adverse events commonly experienced in pediatric oncology clinical trials. The setting incorporated synchronous web-based educational technology. Constructivist learning provides the theoretical framework for this study. Participants evaluated the professional development program at 2 time points: (a) at the conclusion and (b) 4 to 6 weeks afterward, using survey method. Synchronous webinars were both economical and effective in educating clinical research professionals across institutional sites. Participants reported exceptionally high levels of satisfaction with the accessibility, scope, quality, and interactivity of the professional development program. The vast majority of participants reported that the education would assist with reporting adverse events in pediatric oncology clinical trials and this perception persisted into clinical practice. Although the results of this study were intended to guide future educational efforts of the Children's Oncology Group, they may also apply to other cooperative groups.

    Theoretical researches are performed on the alpha-R2MoO6 (R = Y, Gd, Tb Dy, Ho, Er, Tm and Yb) and pyrochlore-type R2Mo2O7 (R = Y, Nd, Sm, Gd, Tb and Dy) rare earth molybdates by using chemical bond theory of dielectric description. The chemical bonding characteristics and their relationship with thermal expansion property and compressibility are explored. The calculated values of linear thermal expansion coefficient (LTEC) and bulk modulus agree well with the available experimental values. The calculations reveal that the LTECs and the bulk moduli do have linear relationship with the ionic radii of the lanthanides: the LTEC decreases from 6.80 to 6.62 10(-6)/K and the bulk modulus increases from 141 to 154 GPa when R goes in the order Gd, Tb Dy, Ho, Er, Tm, and Yb in the alpha-R2MoO6 series; while in the R2Mo2O7 series, the LTEC ranges from 6.80 to 6.61 10(-6)/K and the bulk modulus ranges from 147 to 163 GPa when R varies in the order Nd, Sm, Gd, Tb and Dy.

    Objective: To explore the value of MRI-R_2"* and to compare clinical effect of two iron chelators (Deferasirox and deferoxamine) in iron-overloaded patients. Methods: By completely randomized balanced design, 24 iron-overloaded patients were randomly divided into 2 groups, which consisted of 12 patients treated with Deferasirox and 12 patients treated with deferoxamine. The planned Deferasirox dose was 40 mg · kg"-"1 · d"-"1, and the deferoxamine dose was no less than 50 mg · kg"-"1 · d"-"1. All patients underwent quantitative MRI at the time points of the primary screening, 6 months and 12 months. Pair Wilcoxon rank sum test was used to compare the differences of liver R_2"* values of the 2 groups at various time points respectively. Wilcoxon rank sum test was used to compare the differences of change rate of liver R_2"* values between the two groups at the time point of 6 months, 12 months, respectively. Results: Deferasirox group's liver R_2"* values of primary screening, 6 months and 12 months were 1081, 889 and 712 Hz, while deferoxamine group's liver R_2"* values were 1042, 838 and 488 Hz. There was no statistically significant difference between liver R_2"* values of two groups at primary screening (Z = -0.029, P > 0.05). The change rate of liver R_2"* of Deferasirox group at 12 month was -32%, while it was -58% for the deferoxamine group, and there was statistically significant difference between the two groups (Z = -3.060, P < 0.01). The change rate of serum ferritin of Deferasirox group at 12 month was -15%, while it was -55% for the deferoxamine group, and there was statistically significant difference between the two groups (Z = -2.945, P < 0.01). Conclusion: By using MRI-R_2"*, it suggest that both Deferasirox and deferoxamine can effectively remove liver iron and deferoxamine is superior to Deferasirox. (authors)

    A Role 2 registry (R2R) was developed in 2008 by the US Joint Trauma System (JTS). The purpose of this project was to undertake a preliminary review of the R2R to understand combat trauma epidemiology and related interventions at these facilities to guide training and optimal use of forward surgical capability in the future. A retrospective review of available JTS R2R records; the registry is a convenience sample entered voluntarily by members of the R2 units. Patients were classified according to basic demographics, affiliation, region where treatment was provided, mechanism of injury, type of injury, time and method of transport from point of injury (POI) to R2 facility, interventions at R2, and survival. Analysis included trauma patients aged ≥18 years or older wounded in year 2008 to 2014, and treated in Afghanistan. A total of 15,404 patients wounded and treated in R2 were included in the R2R from February 2008 to September 2014; 12,849 patients met inclusion criteria. The predominant patient affiliations included US Forces, 4,676 (36.4%); Afghan Forces, 4,549 (35.4%); and Afghan civilians, 2,178 (17.0%). Overall, battle injuries predominated (9,792 [76.2%]). Type of injury included penetrating, 7,665 (59.7%); blunt, 4,026 (31.3%); and other, 633 (4.9%). Primary mechanism of injury included explosion, 5,320 (41.4%); gunshot wounds, 3,082 (24.0%); and crash, 1,209 (9.4%). Of 12,849 patients who arrived at R2, 167 (1.3%) were dead; of 12,682 patients who were alive upon arrival, 342 (2.7%) died at R2. This evaluation of the R2R describes the patient profiles of and common injuries treated in a sample of R2 facilities in Afghanistan. Ongoing and detailed analysis of R2R information may provide evidence-based guidance to military planners and medical leaders to best prepare teams and allocate R2 resources in future operations. Given the limitations of the data set, conclusions must be interpreted in context of other available data and analyses, not in isolation

    To assess the psychometric properties of the Arabic adaptation of the Hypomania-Check-List 32-item, second revision (HCL-32-R2) for the detection of bipolarity in major depressive disorder (MDD) inpatients suffering a current major depressive episode (MDE). The "Bipolar Disorders: Improving Diagnosis, Guidance, and Education" Arabic module of the HCL-32-R2 was administered to mother-tongue Arabic MDE inpatients between March 2013 and October 2014. Diagnostic and Statistical Manual Fourth edition (DSM-IV) diagnoses were made adopting the mini-international neuropsychiatric interview, using bipolar disorder (BD) patients as controls. In our sample (n=500, of whom, BD-I=329; BD-II=70; MDD=101), using a cut-off of 17 allowed the HCL-32-R2 to discriminate DSM-IV-defined MDD patients between "true unipolar" (HCL-32-R2(-)) and "sub-threshold bipolar depression" (HCL-32-R2(+)) with sensitivity=82% and specificity=77%. Area under the curve was .883; positive and negative predictive values were 93.44% and 73.23% respectively. Owing to clinical interpretability considerations and consistency with previous adaptations of the HCL-32, a two-factor solution (F1="hyperactive/elated" vs. F2="irritable/distractible/impulsive") was preferred using exploratory and confirmatory factors analyses. Item n.33 ("I gamble more") and n.34 ("I eat more") introduced in the R2 version of the HCL-32 loaded onto F1, though very slightly. Cronbach's alphas were F1=.86 and F2=.60. No cross-validation with any additional validated screening tool. Inpatients only sample; recall bias; no systematic evaluation of eventual medical/psychiatric comorbidities, current/lifetime pharmacological history, or record of severity of current MDE. In our sample, the HCL-32 fairly discriminated between MDD and BD-I but not BD-II, therefore soliciting for replication studies for use in Arabic-speaking depressed inpatients. Copyright © 2015.

    Based on plasma oscillations theory of solids, simple relations have been proposed for the calculation of bond length, specific gravity, homopolar energy gap, heteropolar energy gap, average energy gap, crystal ionicity, bulk modulus, electronic polarizability and dielectric constant of rare earth divalent R+2X and trivalent R+3X monochalcogenides. The specific gravity of nine R+2X, twenty R+3X, and bulk modulus of twenty R+3X monochalcogenides have been calculated for the first time. The calculated values of all parameters are compared with the available experimental and the reported values. A fairly good agreement has been obtained between them. The average percentage deviation of two parameters: bulk modulus and electronic polarizability for which experimental data are known, have also been calculated and found to be better than the earlier correlations.

    In an attempt to optimize leakage characteristics of α-C r2O3 thin films, its dielectric properties were investigated at local and macroscopic scale. The films were grown on Pd(111), Pt(111), and V2O3 (0001), supported on A l2O3 substrate. The local conductivity was measured by conductive atomic force microscopy mapping of C r2O3 surfaces, which revealed the nature of defects that formed conducting paths with the bottom Pd or Pt layer. A strong correlation was found between these electrical defects and the grain boundaries revealed in the corresponding topographic scans. In comparison, the C r2O3 film on V2O3 exhibited no leakage paths at similar tip bias value. Electrical resistance measurements through e-beam patterned top electrodes confirmed the resistivity mismatch between the films grown on different electrodes. The x-ray analysis attributes this difference to the twin free C r2O3 growth on V2O3 seeding.

    This article examines the subjective antecedents of life satisfaction of workers. Adopting a 'bottom-up' perspective, we assessed the unique influence that satisfaction with multiple life domains have on evaluative judgments of overall life satisfaction. Based on a nationwide sample of 530 Chilean workers, we simultaneously tested the effects of seven life domain satisfactions that have been consistently included in extant models of life satisfaction and subjective well-being. These were satisfaction with health, financial situation, social relationships, one's self-worth, leisure-time, family, and work. Having controlled for age and gender, results showed that satisfaction with one's financial situation was the dominant predictor of overall life satisfaction of workers, with a weight of .36. Satisfaction with family, work, and health had effects of .25, .14, and .14, respectively. Interestingly, satisfaction with one's self-worth, leisure-time, and social relationships did not have statistically significant effects on life satisfaction, although the first two showed t values near the critical value.

    We consider a higher derivative gravity theory in four dimensions with a negative cosmological constant and show that vacuum solutions of both Lifshitz type and Schroedinger type with arbitrary dynamical exponent z exist in this system. Then we find an analytic black hole solution which asymptotes to the vacuum Lifshitz solution with z = 3/2 at a specific value of the coupling constant. We analyze the thermodynamic behavior of this black hole and find that the black hole has zero entropy while non-zero temperature, which is very similar to the case of BTZ black holes in new massive gravity at a specific coupling. In addition, we find that the three dimensional Lifshitz black hole recently found by E. Ayon-Beato et al. has a negative entropy and mass when the Newton constant is taken to be positive.

    Job satisfaction is one of the most consistent variables related to employee retention and is especially relevant considering the shortage of radiation therapists and radiation therapy educators in the United States. To investigate job satisfaction levels among radiation therapy educators certified by the American Registry of Radiologic Technologists and employed in programs accredited by the Joint Review Committee on Education in Radiologic Technology. The long form of the Minnesota Satisfaction Questionnaire (MSQ) was mailed to 158 radiation therapy educators to measure job satisfaction. Overall job satisfaction and subscales were calculated based on MSQ methodology. A total of 90 usable surveys were returned for a 56.9% response rate. With a "general satisfaction" score of 69.64, radiation therapy educators ranked in the lowest 25th percentile of the nondisabled norm scale for job satisfaction. Respondents reported higher degrees of job satisfaction on the moral values, social service and achievement subscales. Lower job satisfaction levels were associated with the company policies and practices, advancement and compensation subscales. Radiation therapy educators report low job satisfaction. Educational institutions must tailor recruitment and retention efforts to better reflect the positive aspects of being a radiation therapy educator. Furthermore, improving retention and recruitment efforts might help offset the current shortages of radiation therapy educators and, ultimately, clinical radiation therapists.

  13. Magnetic anisotropy of some R2CO17 compounds

    The singular-point detection technique, in which the second derivative of the magnetization with respect to field is examined, has been used to determine the anisotropy field Bsub(A) = (2/Msub(s)) (K 1 + 2K 2 ) for Sm 2 Co 17 , Er 2 Co 17 , and Tm 2 Co 17 over the temperature range 77 - 300 K. Exrapolation of the initial part of the hard-direction magnetization curve for aligned powders enables K 1 and K 2 to be estimated. For Er 2 Co 17 and Tm 2 Co 17 the rare-earth (R) and cobalt sublattices are oppositely aligned, so that the onset of ordering of the R sublattice leads to a decrease in saturation magnetization as the temperature is lowered. This is in sharp contrast to the rapid increase in K 1 at low temperatures. By subtracting the corresponding Msub(s) values from that of Y 2 Co 17 the temperature dependence of the R sublattice can be determined. It is found that K 1 is directly proportional to the cube of this quantity, indicating the dominance of the rare-earth sublattice in determining the anisotropic properties of these compounds. For Sm 2 Co 17 the anisotropy constant varies very strongly with the reduced magnetization. (author)

    IL-10R2 is a shared cell surface receptor required for the activation of five class 2 cytokines (IL-10, IL-22, IL-26, IL-28, and IL-29) that play critical roles in host defense. To define the molecular mechanisms that regulate its promiscuous binding, we have determined the crystal structure of the IL-10R2 ectodomain at 2.14 {angstrom} resolution. IL-10R2 residues required for binding were identified by alanine scanning and used to derive computational models of IL-10/IL-10R1/IL-10R2 and IL-22/IL-22R1/IL-10R2 ternary complexes. The models reveal a conserved binding epitope that is surrounded by two clefts that accommodate the structural and chemical diversity of the cytokines. These results provide a structural framework for interpreting IL-10R2 single nucleotide polymorphisms associated with human disease.

  16. Preferential occupancy of R2 retroelements on the B chromosomes of the grasshopper Eyprepocnemis plorans.

    Directory of Open Access Journals (Sweden)

    Eugenia E Montiel

    Full Text Available R2 non-LTR retrotransposons exclusively insert into the 28S rRNA genes of their host, and are expressed by co-transcription with the rDNA unit. The grasshopper Eyprepocnemis plorans contains transcribed rDNA clusters on most of its A chromosomes, as well as non-transcribed rDNA clusters on the parasitic B chromosomes found in many populations. Here the structure of the E. plorans R2 element, its abundance relative to the number of rDNA units and its retrotransposition activity were determined. Animals screened from five populations contained on average over 12,000 rDNA units on their A chromosomes, but surprisingly only about 100 R2 elements. Monitoring the patterns of R2 insertions in individuals from these populations revealed only low levels of retrotransposition. The low rates of R2 insertion observed in E. plorans differ from the high levels of R2 insertion previously observed in insect species that have many fewer rDNA units. It is proposed that high levels of R2 are strongly selected against in E. plorans, because the rDNA transcription machinery in this species is unable to differentiate between R2-inserted and uninserted units. The B chromosomes of E. plorans contain an additional 7,000 to 15,000 rDNA units, but in contrast to the A chromosomes, from 150 to over 1,500 R2 elements. The higher concentration of R2 in the inactive B chromosomes rDNA clusters suggests these chromosomes can act as a sink for R2 insertions thus further reducing the level of insertions on the A chromosomes. These studies suggest an interesting evolutionary relationship between the parasitic B chromosomes and R2 elements.

    It has been argued that consensus on the responsibility to protect (R2P) was lost in the UN Security Council as a result of the NATO-led intervention in Libya in 2011. This argument assumes that there was more agreement on R2P before the Libyan intervention than there was afterwards. Yet a close examination of the Security Council’s use of language on R2P shows the opposite: R2P was highly contentious within the Security Council prior to the Libyan intervention, and less so afterwards.

  20. γ-Aminobutyric Acid Type B (GABAB) Receptor Internalization Is Regulated by the R2 Subunit*

    2011-01-01

    γ-Aminobutyric acid type B (GABAB) receptors are important for slow synaptic inhibition in the CNS. The efficacy of inhibition is directly related to the stability of cell surface receptors. For GABAB receptors, heterodimerization between R1 and R2 subunits is critical for cell surface expression and signaling, but how this determines the rate and extent of receptor internalization is unknown. Here, we insert a high affinity α-bungarotoxin binding site into the N terminus of the R2 subunit and reveal its dominant role in regulating the internalization of GABAB receptors in live cells. To simultaneously study R1a and R2 trafficking, a new α-bungarotoxin binding site-labeling technique was used, allowing α-bungarotoxin conjugated to different fluorophores to selectively label R1a and R2 subunits. This approach demonstrated that R1a and R2 are internalized as dimers. In heterologous expression systems and neurons, the rates and extents of internalization for R1aR2 heteromers and R2 homomers are similar, suggesting a regulatory role for R2 in determining cell surface receptor stability. The fast internalization rate of R1a, which has been engineered to exit the endoplasmic reticulum, was slowed to that of R2 by truncating the R1a C-terminal tail or by removing a dileucine motif in its coiled-coil domain. Slowing the rate of internalization by co-assembly with R2 represents a novel role for GPCR heterodimerization whereby R2 subunits, via their C terminus coiled-coil domain, mask a dileucine motif on R1a subunits to determine the surface stability of the GABAB receptor.

    2017-12-01

    The Rolling Deck to Repository program (R2R) is creating and evaluating a new browse portal based on the SuAVE platform and the R2R linked data graph. R2R manages the underway sensor data collected by the fleet of US academic research vessels, and provides a discovery and access point to those data at its website, www.rvdata.us. R2R has a database-driven search interface, but seeks a more capable and extensible browse interface that could be built off of the substantial R2R linked data resources. R2R's Linked Data graph organizes its data holdings around key concepts (e.g. cruise, vessel, device type, operator, award, organization, publication), anchored by persistent identifiers where feasible. The "Survey Analysis via Visual Exploration" or SuAVE platform (suave.sdsc.edu) is a system for online publication, sharing, and analysis of images and metadata. It has been implemented as an interface to diverse data collections, but has not been driven off of linked data in the past. SuAVE supports several features of interest to R2R, including faceted searching, collaborative annotations, efficient subsetting, Google maps-like navigation over an image gallery, and several types of data analysis. Our initial SuAVE-based implementation was through a CSV export from the R2R PostGIS-enabled PostgreSQL database. This served to demonstrate the utility of SuAVE but was static and required reloading as R2R data holdings grew. We are now working to implement a SPARQL-based ("RDF Query Language") service that directly leverages the R2R Linked Data graph and offers the ability to subset and/or customize output.We will show examples of SuAVE faceted searches on R2R linked data concepts, and discuss our experience to date with this work in progress.

  2. A descriptive study of high school Latino and Caucasian students' values about math, perceived math achievement and STEM career choice

    Rodriguez Flecha, Samuel

    The purpose of this study was to examine high school students' math values, perceived math achievement, and STEM career choice. Participants (N=515) were rural high school students from the U.S. Northwest. Data was collected by administering the "To Do or Not to Do:" STEM pilot survey. Most participants (n=294) were Latinos, followed by Caucasians (n=142). Fifty-three percent of the students rated their math achievement as C or below. Of high math students, 57% were male. Females were 53% of low math students. Caucasians (61%) rated themselves as high in math in a greater proportion than Latinos (39%). Latinos (58%) rated themselves as low in math in a greater proportion than Caucasians (39%). Math Values play a significant role in students' perceived math achievement. Internal math values (r =.68, R2 =.46, p =.001) influenced perceived math achievement regardless of gender (males: r =.70, R2 =.49, p =.001; females: r =.65, R2 =.43, p =.001), for Latinos (r =.66, R2 =.44, p =.001), and Caucasians (r =.72, R2 =.51, p =.001). External math values (r =.53, R2 =.28, p =.001) influenced perceived math achievement regardless of gender (males: r =.54, R2 =.30, p =.001; females: r =.49, R2 =.24, p =.001), for Latinos (r =.47, R2 =.22, p =.001), and Caucasians (r =.58, R2 =.33, p =.001). Most high-math students indicated an awareness of being good at math at around 11 years old. Low-math students said that they realized that math was difficult for them at approximately 13 years of age. The influence of parents, teachers, and peers may vary at different academic stages. Approximately half of the participants said there was not a person who had significantly impacted their career choice; only a minority said their parents and teachers were influencing them to a STEM career. Parents and teachers are the most influential relationships in students' career choice. More exposure to STEM role models and in a variety of professions is needed.

    2016-06-01

    In this work, we demonstrate that in the presence of ordered sub-voxel structure such as tubular organization, biomaterials with molecular isotropy exhibits only apparent R2* anisotropy, while biomaterials with molecular anisotropy exhibit both apparent R2* and susceptibility anisotropy by means of susceptibility tensor imaging (STI). To this end, R2* and STI from gradient echo magnitude and phase data were examined in phantoms made from carbon fiber and Gadolinium (Gd) solutions with and without intrinsic molecular order and sub-voxel structure as well as in the in vivo brain. Confidence in the tensor reconstructions was evaluated with a wild bootstrap analysis. Carbon fiber showed both apparent anisotropy in R2* and anisotropy in STI, while the Gd filled capillary tubes only showed apparent anisotropy on R2*. Similarly, white matter showed anisotropic R2* and magnetic susceptibility with higher confidence, while the cerebral veins displayed only strong apparent R2* tensor anisotropy. Ordered sub-voxel tissue microstructure leads to apparent R2* anisotropy, which can be found in both white matter tracts and cerebral veins. However, additional molecular anisotropy is required for magnetic susceptibility anisotropy, which can be found in white matter tracts but not in cerebral veins. Copyright © 2016 Elsevier Inc.

    2015-01-01

    We present R2U2, a novel framework for runtime monitoring of security properties and diagnosing of security threats on-board Unmanned Aerial Systems (UAS). R2U2, implemented in FPGA hardware, is a real-time, REALIZABLE, RESPONSIVE, UNOBTRUSIVE Unit for security threat detection. R2U2 is designed to continuously monitor inputs from the GPS and the ground control station, sensor readings, actuator outputs, and flight software status. By simultaneously monitoring and performing statistical reasoning, attack patterns and post-attack discrepancies in the UAS behavior can be detected. R2U2 uses runtime observer pairs for linear and metric temporal logics for property monitoring and Bayesian networks for diagnosis of security threats. We discuss the design and implementation that now enables R2U2 to handle security threats and present simulation results of several attack scenarios on the NASA DragonEye UAS.

    2007-08-01

    In recent years, mental health services across Europe have undergone major organizational change with a move from institutional to community care. In such a context, the impact of change on the job satisfaction of psychiatric nurses has received little attention in the literature. This paper reports on the job satisfaction of psychiatric nurses and data were collected in 2003. The population of qualified psychiatric nurses (n = 800) working in a defined geographical health board area was surveyed. Methodological triangulation with a between-methods approach was used in the study. Data were collected on job satisfaction using a questionnaire adopted from the Occupational Stress Indicator. A response rate of 346 (43%) was obtained. Focus groups were used to collect qualitative data. Factors influencing levels of job satisfaction predominantly related to the nurses work location. Other factors influencing job satisfaction included choice of work location, work routine, off duty/staff allocation arrangements, teamwork and working environment. The results of the study highlight to employers of psychiatric nurses the importance of work location, including the value of facilitating staff with choices in their working environment, which may influence the recruitment and retention of nurses in mental health services.

  6. Can multi-slice or navigator-gated R2* MRI replace single-slice breath-hold acquisition for hepatic iron quantification?

    Liver R2* values calculated from multi-gradient echo (mGRE) magnetic resonance images (MRI) are strongly correlated with hepatic iron concentration (HIC) as shown in several independently derived biopsy calibration studies. These calibrations were established for axial single-slice breath-hold imaging at the location of the portal vein. Scanning in multi-slice mode makes the exam more efficient, since whole-liver coverage can be achieved with two breath-holds and the optimal slice can be selected afterward. Navigator echoes remove the need for breath-holds and allow use in sedated patients. To evaluate if the existing biopsy calibrations can be applied to multi-slice and navigator-controlled mGRE imaging in children with hepatic iron overload, by testing if there is a bias-free correlation between single-slice R2* and multi-slice or multi-slice navigator controlled R2*. This study included MRI data from 71 patients with transfusional iron overload, who received an MRI exam to estimate HIC using gradient echo sequences. Patient scans contained 2 or 3 of the following imaging methods used for analysis: single-slice images (n = 71), multi-slice images (n = 69) and navigator-controlled images (n = 17). Small and large blood corrected region of interests were selected on axial images of the liver to obtain R2* values for all data sets. Bland-Altman and linear regression analysis were used to compare R2* values from single-slice images to those of multi-slice images and navigator-controlled images. Bland-Altman analysis showed that all imaging method comparisons were strongly associated with each other and had high correlation coefficients (0.98 ≤ r ≤ 1.00) with P-values ≤0.0001. Linear regression yielded slopes that were close to 1. We found that navigator-gated or breath-held multi-slice R2* MRI for HIC determination measures R2* values comparable to the biopsy-validated single-slice, single breath-hold scan. We conclude that these three R2* methods can be

    Liver R2* values calculated from multi-gradient echo (mGRE) magnetic resonance images (MRI) are strongly correlated with hepatic iron concentration (HIC) as shown in several independently derived biopsy calibration studies. These calibrations were established for axial single-slice breath-hold imaging at the location of the portal vein. Scanning in multi-slice mode makes the exam more efficient, since whole-liver coverage can be achieved with two breath-holds and the optimal slice can be selected afterward. Navigator echoes remove the need for breath-holds and allow use in sedated patients. To evaluate if the existing biopsy calibrations can be applied to multi-slice and navigator-controlled mGRE imaging in children with hepatic iron overload, by testing if there is a bias-free correlation between single-slice R2* and multi-slice or multi-slice navigator controlled R2*. This study included MRI data from 71 patients with transfusional iron overload, who received an MRI exam to estimate HIC using gradient echo sequences. Patient scans contained 2 or 3 of the following imaging methods used for analysis: single-slice images (n = 71), multi-slice images (n = 69) and navigator-controlled images (n = 17). Small and large blood corrected region of interests were selected on axial images of the liver to obtain R2* values for all data sets. Bland-Altman and linear regression analysis were used to compare R2* values from single-slice images to those of multi-slice images and navigator-controlled images. Bland-Altman analysis showed that all imaging method comparisons were strongly associated with each other and had high correlation coefficients (0.98 ≤ r ≤ 1.00) with P-values ≤0.0001. Linear regression yielded slopes that were close to 1. We found that navigator-gated or breath-held multi-slice R2* MRI for HIC determination measures R2* values comparable to the biopsy-validated single-slice, single breath-hold scan. We conclude that these three R2* methods can be

    The U.S. National Science Foundation supports a fleet of academic research vessels operating throughout the world's oceans. In addition to supporting the mission-specific goals of each expedition, these vessels routinely deploy a suite of underway environmental sensors, operating like mobile observatories. Recognizing that the data from these instruments have value beyond each cruise, NSF funded R2R in 2009 to ensure that these data are routinely captured, cataloged and described, and submitted to the appropriate national repository for long-term public access. In 2013, R2R joined the Ocean Data Interoperability Platform (ODIP; http://odip.org/). The goal of ODIP is to remove barriers to the effective sharing of data across scientific domains and international boundaries, by providing a forum to harmonize diverse regional systems. To advance this goal, ODIP organizes international workshops to foster the development of common standards and develop prototypes to evaluate and test potential standards and interoperability solutions. ODIP includes major organizations engaged in ocean data stewardship in the EU, US, and Australia, supported by the International Oceanographic Data and Information Exchange (IODE). Within the broad scope of ODIP, R2R focuses on contributions in 4 key areas: ● Implement a 'Linked Open Data' approach to disseminate data and documentation, using existing World Wide Web Consortium (W3C) specifications and machine-readable formats. Exposing content as Linked Open Data will provide a simple mechanism for ODIP collaborators to browse and compare data sets among repositories. ● Map key vocabularies used by R2R to their European and Australian counterparts. The existing heterogeneity among terms inhibits data discoverability, as a user searching on the term with which s/he is familiar may not find all data of interest. Mapping key terms across the different ODIP partners, relying on the backbone thesaurus provided by the NERC Vocabulary Server

    The food contaminant acrylamide (AA) is usually recognized as a probable human carcinogen. In addition, AA has also been found able to induce male infertility in animals. Interestingly, resent research work revealed that the toxic effect of AA on the ability of male reproduction in vivo may due to glycidamide (GA) which is the metabolite of AA. In this study, R2C Leydig cells was used to investigate the toxic effects of GA on progesterone production. GA caused dose-dependent inhibition on the cell growth, with IC 25 , IC 50, and IC 75 values found at 0.635, 0.872, and 1.198 mM, respectively. The results of single cell gel/Comet assay showed that GA significantly induced early-phase cell apoptosis, reduced progesterone production, as well as decreasing the protein expression of steroidogenic acute regulatory (StAR) in R2C cells. Furthermore, GA induced overproduction of intracellular reactive oxygen species (ROS), upregulated Bax expression, decreased mitochondrial membrane potential, and triggered mitochondria-mediated cell apoptosis. Consequently, the downstream effector caspase-3 was activated, resulting in Leydig cells apoptosis. Overall, our results showed that GA could damage R2C Leydig cells by the lesion of the ability of progesterone genesis and inducing cells apoptosis. Copyright © 2016 Elsevier Ltd.

    2016-04-01

    Since the introduction of Channelrhodopsin-2 (ChR2) to neuroscience, optogenetics technology was developed, making it possible to activate specific neurons or circuits with spatial and temporal precision. Various ChR2 transgenic animal models have been generated and are playing important roles in revealing the mechanisms of neural activities, mapping neural circuits, controlling the behaviors of animals as well as exploring new strategy for treating the neurological diseases in both central and peripheral nervous system. An animal including humans senses environments through Aristotle's five senses (sight, hearing, smell, taste and touch). Usually, each sense is associated with a kind of sensory organ (eyes, ears, nose, tongue and skin). Is it possible that one could hear light, smell light, taste light and touch light? When ChR2 is targeted to different peripheral sensory neurons by viral vectors or generating ChR2 transgenic animals, the animals can sense the light as various sensations such as hearing, touch, pain, smell and taste. In this review, we focus on ChR2 transgenic animals in the peripheral nervous system. Firstly the working principle of ChR2 as an optogenetic actuator is simply described. Then the current transgenic animal lines where ChR2 was expressed in peripheral sensory neurons are presented and the findings obtained by these animal models are reviewed.

    We have conducted simultaneous JHK{sub s}-band imaging circular and linear polarimetry of the Monoceros R2 (Mon R2) cluster. We present results from deep and wide near-infrared linear polarimetry of the Mon R2 region. Prominent and extended polarized nebulosities over the Mon R2 field are revisited, and an infrared reflection nebula associated with the Mon R2 cluster and two local reflection nebulae, vdB 67 and vdB 69, is detected. We also present results from deep imaging circular polarimetry in the same region. For the first time, the observations show relatively high degrees of circular polarization (CP) in Mon R2, with as much as approximately 10% in the K{sub s} band. The maximum CP extent of a ring-like nebula around the Mon R2 cluster is approximately 0.60 pc, while that of a western nebula, around vdB 67, is approximately 0.24 pc. The extended size of the CP is larger than those seen in the Orion region around IRc2, while the maximum degree of CP of ∼10% is smaller than those of ∼17% seen in the Orion region. Nonetheless, both the CP size and degree of this region are among the largest in our infrared CP survey of star-forming regions. We have also investigated the time variability of the degree of the polarization of several infrared sources and found possible variations in three sources.

    The purpose of this study was to compare histogram analysis of apparent diffusion coefficient (ADC) and R2* for differentiating low-grade from high-grade clear cell renal cell carcinoma (RCC). Forty-six patients with pathologically confirmed clear cell RCC underwent preoperative BOLD and DWI MRI of the kidneys. ADCs based on the entire tumor volume were calculated with b value combinations of 0 and 800 s/mm(2). ROI-based R2* was calculated with eight TE combinations of 6.7-22.8 milliseconds. Histogram analysis of tumor ADCs and R2* values was performed to obtain mean; median; width; and fifth, 10th, 90th, and 95th percentiles and histogram inhomogeneity, kurtosis, and skewness for all lesions. Thirty-three low-grade and 13 high-grade clear cell RCCs were found at pathologic examination. The TNM classification and tumor volume of clear cell RCC significantly correlated with histogram ADC and R2* (ρ = -0.317 to 0.506; p histogram ADC and R2* indexes, 10th percentile ADC had the highest accuracy (91.3%) in discriminating low- from high-grade clear cell RCC. R2* in discriminating hemorrhage was achieved with a threshold of 68.95 Hz. At this threshold, high-grade clear cell RCC had a significantly higher prevalence of intratumor hemorrhage (high-grade, 76.9%; low-grade, 45.4%; p Histogram analysis of ADC and R2* allows differentiation of low- from high-grade clear cell RCC with high accuracy.

    Carotenoids are yellow, orange, and red pigments that contribute to the beautiful colors and nutritive value of many flowers and fruits. The structural genes in the highly conserved carotenoid biosynthetic pathway have been well characterized in multiple plant systems, but little is known about the transcription factors that control the expression of these structural genes. By analyzing a chemically induced mutant of Mimulus lewisii through bulk segregant analysis and transgenic experiments, we have identified an R2R3-MYB, Reduced Carotenoid Pigmentation 1 (RCP1), as the first transcription factor that positively regulates carotenoid biosynthesis during flower development. Loss-of-function mutations in RCP1 lead to down-regulation of all carotenoid biosynthetic genes and reduced carotenoid content in M. lewisii flowers, a phenotype recapitulated by RNA interference in the wild-type background. Overexpression of this gene in the rcp1 mutant background restores carotenoid production and, unexpectedly, results in simultaneous decrease of anthocyanin production in some transgenic lines by down-regulating the expression of an activator of anthocyanin biosynthesis. Identification of transcriptional regulators of carotenoid biosynthesis provides the 'toolbox' genes for understanding the molecular basis of flower color diversification in nature and for potential enhancement of carotenoid production in crop plants via genetic engineering. © 2015 The Authors.

    Larger Danish banks score lower on customer satisfaction than minor Danish banks. The purpose of this empirical qualitative study is to enlighten this satisfaction paradox. The findings revealed that different satisfactions models are in play. More specifically, the larger banks in Denmark have...... undergone a transformation from a physical realm to a virtual realm. Hence, the personal relationship between the customer and bank employee has also changed. The customer perception of this is rather problematic. More specifically, the changes have diminished customers possibilities to form satisfaction...... judgments. Moreover, the larger banks also loose valuable insights in what the customers value. Without this knowledge a string of strategic business decisions will not be made based on ideal information. The originality of this study is examining and emphasizing coherence in satisfaction models in a buyer...

    2014-05-01

    The heterogeneity of terminology used in describing data creates a barrier to the efficient discovery and re-use of data, particularly across institutional, programmatic, and disciplinary boundaries. Here we explore the outcomes of a student project to crosswalk terms between the Rolling Deck to Repository (R2R) program and other international systems, as part of the Ocean Data Interoperability Platform (ODIP). R2R is a US program developing and implementing an information management system to preserve and provide access to routine underway data collected by U.S academic research vessels. R2R participates in ODIP, an international forum for improving the interoperability and effective sharing of marine data resources through technical workshops and joint prototypes. The vocabulary mapping effort lays a foundation for future ocean data portals through which users search and access international ocean data using familiar terms. R2R describes its data with a suite of controlled vocabularies (http://www.rvdata.us/voc) some of which were developed locally or are specific to the US. The goal of this student project is to crosswalk local/national vocabularies to authoritative international vocabularies, where they exist, or to vocabularies widely used by ODIP partners. Specifically, R2R developed the following crosswalks: R2R science party names to ORCID person identifiers, UNOLS ports to SeaDataNet Ports Gazetteer, R2R Device Models to NVS SeaVoX Device Catalog, and R2R Organizations to the European Directory of Marine Organizations (EDMO). Mappings were done in simple spreadsheets using synonymy relationships only, and will be published as part of the R2R Linked Data resources. The level of success in crosswalking was variable. The majority of ports were successfully mapped. Differences in the character sets (i.e. whether diacritic marks were used) caused automated matching to fail occasionally, but the number of ports was small enough that these could be manually

    Full Text Available Traffic accidents are terrible scourge that occur in many countries, specially for developing countries where transportation affairs like tangled yarn. Besides functioning as an engine compartment cover, the hood of modern compact SUV can also help to manage the impact energy of a pedestrian’s head in a vehicle-pedestrian impact. This paper presents outer hood design of Esemka R2 that has a potential to improve hood’s ability and also to absorb the impact energy of a pedestrian’s head. The developed method for the design of an outer hood configuration aims to provide a robust design and homogeneous of Head Injury Criterion (HIC for impact position at WAD 1000 and three different thicknesses (1.25 mm, 1.35 mm & 1.50 mm of outer hood panel of Esemka R2 compact SUV, taking into consideration the limited space available for deformation. The non-linear Finite Element Analysis (FEA software (Explicit Dynamics was used in this research to simulate the testing procedurs of head impact for child pedestrian. The results show that the average of comparison dimensional of outer hood panel of Esemka R2 was 4.89 mm. The minimum of deformation space meet the requirement for HIC value which required obtaining robust and homogeneous head impact performance. Outer hood thickness and materials were identified as the factors to influence the stress and HIC value of the hood. By comparing all outer hood panels, aluminium alloy as the best selected material which has the lowest value is 32.78% for the pedestrian protection.

    An effective synthesis of chiral atropoisomeric biaryl phosphine-olefin compounds via palladium-catalyzed enantioselective C-H olefination has been developed for the first time. The reactions are operationally simple, tolerate wide functional groups, and have a good ee value. Notably, P(O)R 2 not only acts as the directing group to direct C-H activation in order to make a useful ligand but also serves to facilitate composition of the product in a useful manner in this transformation.

    2017-01-01

    Dynamic monitoring of software and system health of a complex cyber-physical system requires observers that continuously monitor variables of the embedded software in order to detect anomalies and reason about root causes. There exists a variety of techniques for code instrumentation, but instrumentation might change runtime behavior and could require costly software re-certification. In this paper, we present R2U2E, a novel realization of our real-time, Realizable, Responsive, and Unobtrusive Unit (R2U2). The R2U2E observers are executed in parallel on a dedicated 16-core EPIPHANY co-processor, thereby avoiding additional computational overhead to the system under observation. A DMA-based shared memory access architecture allows R2U2E to operate without any code instrumentation or program interference.

    Science.gov (United States)

    2011-01-01

    Background With continuing identification of novel structured noncoding RNAs, there is an increasing need to create schematic diagrams showing the consensus features of these molecules. RNA structural diagrams are typically made either with general-purpose drawing programs like Adobe Illustrator, or with automated or interactive programs specific to RNA. Unfortunately, the use of applications like Illustrator is extremely time consuming, while existing RNA-specific programs produce figures that are useful, but usually not of the same aesthetic quality as those produced at great cost in Illustrator. Additionally, most existing RNA-specific applications are designed for drawing single RNA molecules, not consensus diagrams. Results We created R2R, a computer program that facilitates the generation of aesthetic and readable drawings of RNA consensus diagrams in a fraction of the time required with general-purpose drawing programs. Since the inference of a consensus RNA structure typically requires a multiple-sequence alignment, the R2R user annotates the alignment with commands directing the layout and annotation of the RNA. R2R creates SVG or PDF output that can be imported into Adobe Illustrator, Inkscape or CorelDRAW. R2R can be used to create consensus sequence and secondary structure models for novel RNA structures or to revise models when new representatives for known RNA classes become available. Although R2R does not currently have a graphical user interface, it has proven useful in our efforts to create 100 schematic models of distinct noncoding RNA classes. Conclusions R2R makes it possible to obtain high-quality drawings of the consensus sequence and structural models of many diverse RNA structures with a more practical amount of effort.

    Tributyltin (TBT), which has been widely used as an antifouling agent in paints, is a common environmental pollutant. Although the toxicity of high-dose TBT has been extensively reported, the effects of low concentrations of TBT are relatively less well studied. We have previously reported that low-concentration TBT decreases α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-type glutamate receptor subunit 2 ( GluR2 ) expression in cortical neurons and enhances neuronal vulnerability to glutamate. However, the mechanism of this TBT-induced GluR2 decrease remains unknown. Therefore, we examined the effects of TBT on the activity of transcription factors that control GluR2 expression. Exposure of primary cortical neurons to 20 nM TBT for 3 h to 9 days resulted in a decrease in GluR2 mRNA expression. Moreover, TBT inhibited the DNA binding activity of nuclear respiratory factor-1 (NRF-1), a transcription factor that positively regulates the GluR2 . This result indicates that TBT inhibits the activity of NRF-1 and subsequently decreases GluR2 expression. In addition, 20 nM TBT decreased the expression of genes such as cytochrome c, cytochrome c oxidase (COX) 4, and COX 6c, which are downstream of NRF-1. Our results suggest that NRF-1 inhibition is an important molecular action of the neurotoxicity induced by low-concentration TBT.

The NSF-funded Rolling Deck to Repository (R2R) program is working with the fleet community to routinely document, assess, and preserve data from the underway sensor systems on each vessel. The R2R facility maintains a master catalog of vessels, instrument systems, operating institutions, cruises, personnel, and data sets. In less than two years, the catalog has grown to over 2,000 cruises including unique identifiers for vessel deployments, project titles, chief scientists, dates, ports, survey targets, and navigation tracks. This master catalog is of great value to peer data systems, ranging from large national data centers to small disciplinary data offices, as an aid in organizing, extending, and quality controlling their own collections and finding related data from authoritative sources.

    The Rolling Deck to Repository (R2R; http://rvdata.us/) program is developing infrastructure to routinely document, assess, and preserve the underway sensor data from U.S. academic research vessels. The R2R master catalog of vessels, instrument systems, operating institutions, cruises, personnel, data sets, event logs, and field reports has grown to over 2,200 cruises in less than two years, and is now accessible via Web services. This catalog is of great value to peer data systems, ranging from large inter/national data centers to small disciplinary data offices, as an aid in quality controlling their own collections and finding related data from authoritative sources.

R2R's metric of success is the degree to which peer data systems harvest and reuse our content. R2R is working collaboratively with the NOAA National Data Centers and the NSF-funded Biological and Chemical Oceanography Data Management Office (BCO-DMO) on a range of Linked Data pilot applications, including production of ISO-compliant metadata and deployment of a RDF Query Language (SPARQL) interface. Our objective is to support a distributed, loosely federated network of

  10. R2SM: a package for the analytic computation of the R2 Rational terms in the Standard Model of the Electroweak interactions

    The analytical package written in FORM presented in this paper allows the computation of the complete set of Feynman Rules producing the Rational terms of kind R 2 contributing to the virtual part of NLO corrections in the Standard Model of the Electroweak interactions. Building block topologies filled by means of generic scalars, vectors and fermions, allowing to build these Feynman Rules in terms of specific elementary particles, are explicitly given in the R ξ gauge class, together with the automatic dressing procedure to obtain the Feynman Rules from them. The results in more specific gauges, like the 't Hooft Feynman one, follow as particular cases, in both the HV and the FDH dimensional regularization schemes. As a check on our formulas, the gauge independence of the total Rational contribution (R 1 +R 2 ) to renormalized S-matrix elements is verified by considering the specific example of the H →γγ decay process at 1-loop. This package can be of interest for people aiming at a better understanding of the nature of the Rational terms. It is organized in a modular way, allowing a further use of some its files even in different contexts. Furthermore, it can be considered as a first seed in the effort towards a complete automation of the process of the analytical calculation of the R 2 effective vertices, given the Lagrangian of a generic gauge theory of particle interactions.

    2014-07-01

    Full Text Available The paper proposes a structure of a composite Index of Local Government Employees Satisfaction (ESI in Poland. The index provides a based on four sub-indices synthetic assessment of the level of employee satisfaction with the employment in local government offices. The sub-indices have been constructed using an exploratory factor analysis with the VARIMAX one. The ESI and sub-indices values have been normalized in the range of [0–100%], wherein higher ESI values indicate higher employee satisfaction. The proposed approach is used to assess the level of employee satisfaction with the employment in some local government units in the West Pomerania province. The analysis was based on the results of the measurements made in 2009–2010 by comparing the results of two groups of employees separated on the basis of a criterion of their place of employment.

    The ability to evaluate the cerebral microvascular structure and function is crucial for investigating pathological processes in brain disorders. Previous angiographic methods based on blood oxygen level-dependent (BOLD) contrast offer appropriate visualization of the cerebral vasculature, but these methods remain to be optimized in order to extract more comprehensive information. This study aimed to integrate the advantages of BOLD MRI in both structural and functional vascular assessments. The BOLD contrast was manipulated by a carbogen challenge, and signal changes in gradient-echo images were computed to generate ΔR2* maps. Simultaneously, a functional index representing the regional cerebral blood volume was derived by normalizing the ΔR2* values of a given region to those of vein-filled voxels of the sinus. This method is named 3D gas ΔR2*-mMRA (microscopic MRA). The advantages of using 3D gas ΔR2*-mMRA to observe the microvasculature include the ability to distinguish air-tissue interfaces, a high vessel-to-tissue contrast, and not being affected by damage to the blood-brain barrier. A stroke model was used to demonstrate the ability of 3D gas ΔR2*-mMRA to provide information about poststroke revascularization at 3 days after reperfusion. However, this technique has some limitations that cannot be overcome and hence should be considered when it is applied, such as magnifying vessel sizes and predominantly revealing venous vessels.

    Xiong, Dehua; Cheng, Jinshu; Li, Hong

    2010-01-01

    The crystallization behavior and microstructure of R 2 O-Al 2 O 3 -SiO 2 (R means K, Na and Li) glass were investigated by means of differential scanning calorimeter (DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The crystallization kinetic parameters including the crystallization apparent activation energy (E a ), the Avrami parameter (n), glass transition temperature (T g ) and the activity energy of glass transition (E t ) were also measured with different methods. The results have shown that: the DSC traces of composition A parent glass have two different precipitation crystallization peaks corresponding to E a1 (A) = 151.4 kJ/mol (Li 2 SiO 3 ) and E a2 (A) = 623.1 kJ/mol (Li 2 Si 2 O 5 ), the average value of n = 1.70 (Li 2 Si 2 O 5 ) for the surface crystallization and E t (A) = 202.8 kJ/mol. And E a (B) = 50.7 kJ/mol (Li 2 SiO 3 ), the average value of n = 3.89 (Li 2 SiO 3 ) for the bulk crystallization and E t (B) = 220.4 kJ/mol for the composition B parent glass. Because of the content of R 2 O is bigger than composition A, composition B parent glass has a lower E a , T g and a larger n, E t .

    The aim of this study was to investigate whether MR imaging of trabecular bone structure using magnetic inhomogeneity measurements is related to the amount of bone mineral in human vertebrae. Weight, bone mineral content (BMC DXA ), bone mineral per area (BMA DXA ) and bone mineral density (BMD CT ) were determined in 12 defatted human lumbar vertebrae (L2-L4) by weighing, dual X-ray absorptiometry (DXA) and CT. Inhomogeneity caused by susceptibility differences between trabecular bone and surrounding water was studied with MR imaging at 1.5 T using the GESFIDE sequence. The pulse sequence determines the transverse relaxation rate R2 * and its two components, the non-reversible transverse relaxation rate (R2) and the reversible transverse relaxation rate (R2'; i. e. relaxation rate due to magnetic susceptibility) in a single scan. Voxel size was 0.9 x 1.9 x 5.0 mm. Positive significant correlations between R2' and weight, BMC DXA , BMA DXA and BMD CT were observed (r > 0.61 and p DXA and BMD CT (r > 0.66 and p DXA . Thus, R2' measurements are related to the amount of bone mineral, but they also provide information which is not obtainable from bone mineral measurements. (orig.) (orig.)

    Tributyltin (TBT), a common environmental contaminant, is widely used as an antifouling agent in paint. We previously reported that exposure of primary cortical neurons to TBT in vitro decreased the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit glutamate receptor 2 (GluR2) expression and subsequently increased neuronal vulnerability to glutamate. Therefore, to identify whether GluR2 expression also decreases after TBT exposure in vivo, we evaluated the changes in GluR2 expression in the mouse brain after prenatal or postnatal exposure to 10 and 25 ppm TBT through pellet diets. Although the mean feed intake and body weight did not decrease in TBT-exposed mice compared with that in control mice, GluR2 expression in the cerebral cortex and hippocampus decreased after TBT exposure during the prenatal period. These results indicate that a decrease in neuronal GluR2 may be involved in TBT-induced neurotoxicity, especially during the fetal period.

    This study showed that an R2R3-MYB transcription factor, OjMYB1, is involved in anthocyanin biosynthesis and accumulation in Oenanthe javanica. Anthocyanins can be used as safe natural food colorants, obtained from many plants. R2R3-MYB transcription factors (TFs) play important roles in anthocyanins biosynthesis during plant development. Oenanthe javanica is a popular vegetable with high nutritional values and numerous medical functions. O. javanica has purple petioles that are mainly due to anthocyanins accumulation. In the present study, the gene encoding an R2R3-MYB TF, OjMYB1, was isolated from purple O. javanica. Sequencing results showed that OjMYB1 contained a 912-bp open reading frame encoding 303 amino acids. Sequence alignments revealed that OjMYB1 contained bHLH-interaction motif ([DE]Lx2[RK]x3Lx6Lx3R) and ANDV motif ([A/G]NDV). Phylogenetic analysis indicated that the OjMYB1 classified into the anthocyanins biosynthesis clade. Subcellular localization assay showed that OjMYB1 was a nuclear protein in vivo. The heterologous expression of OjMYB1 in Arabidopsis could enhance the anthocyanins content and up-regulate the expression levels of the structural genes-related anthocyanins biosynthesis. Yeast two-hybrid assay indicated that OjMYB1 could interact with AtTT8 and AtEGL3 proteins. Enzymatic analysis revealed that overexpression of OjMYB1 gene up-regulated the enzyme activity of 3-O-glycosyltransferase encoded by AtUGT78D2 in transgenic Arabidopsis. Our results provided a comprehensive understanding of the structure and function of OjMYB1 TF in O. javanica.

    Full Text Available Drought stress can trigger the production of ABA in plants, in response to adverse conditions, which induces the transcript of stress-related marker genes. The R2R3 MYB TFs are implicated in regulation of various plants developmental, metabolic and multiple environmental stress responses. Here, a R2R3-MYB cloned gene, GaMYB62L, was transformed in Arabidopsis and was functionally characterized. The GaMYB62L protein contains two SANT domains with a conserved R2R3 imperfect repeats. The GaMYB62L cDNA is 1,017 bp with a CDS of 879, encodes a 292-residue polypeptide with MW of 38.78 kD and a pI value of 8.91. Overexpressed GaMYB62L transgenic Arabidopsis have increased proline and chlorophyll content, superior seed germination rate under salt and osmotic stress, less water loss rate with reduced stomatal apertures, high drought avoidance as compared to WT on water deprivation and also significant plant survival rates at low temperature. In addition, overexpressed GaMYB62L lines were more sensitive to ABA mediated germination and root elongation assay. Moreover, ABA induced GaMYB62L overexpression, enhanced the expression of ABA stress related marker genes like RD22, COR15A, ADH1, and RD29A. Together, overexpression of GaMYB62L suggested having developed better drought, salt and cold tolerance in transgenic Arabidopsis and thus presented it as a prospective candidate gene to achieve better abiotic stress tolerance in cotton crop.

    Rare earth sesquiselenides of the Th 3 P 4 structure show variable electric properties over their homogeneity range, i.e., ranging from metallic (R 3 Se 4 ) to semimetallic (R 2 Se/sub 3-x/, where 0.14 > x > 0) to semiconducting (R 2 Se 3 ). The composition change is due to the formation of metal vacancies in the Th 3 P 4 structure with no vacancies at R 3 Se 4 and 4.75 at. % vacancies at R 2 Se 3 . The rare earth sesquiselenides are also refractory materials and therefore are of interest for high temperature thermoelectric applications. Preliminary results of thermoelectric power and electrical resistivity measurements on the light lanthanide sesquiselenides (La through Sm) are presented

    The Autonomous Rendezvous, Control And Docking Experiment — Reflight 2 (ARCADE-R2) is a technology demonstrator aiming to prove automatic attitude determination and control, rendezvous and docking capabilities for small scale spacecraft and aircraft. The development of such capabilities could be fundamental to create, in the near future, fleets of cooperative, autonomous unmanned aerial vehicles for mapping, surveillance, inspection and remote observation of hazardous environments; small-class satellites could also benefit from the employment of docking systems to extend and reconfigure their mission profiles. ARCADE-R2 is designed to test these technologies on a stratospheric flight on board the BEXUS-17 balloon, allowing to demonstrate them in a harsh environment subjected to gusty winds and high pressure and temperature variations. In this paper, ARCADE-R2 architecture is introduced and the main results obtained from a stratospheric balloon flight are presented.

  8. Thermal instability observations during ramp tests in the Studsvik R2 reactor

    Roennberg, G.; Kjaer-Pedersen, N.

    1984-01-01

    A series of ramp tests on ENC-built BWR fuel from the Big Rock Point reactor was performed in September 1982 in the Studsvik R2 Reactor. The tests involved segmented rods with a burnup of 18 MWd/KgU, and constituted part of the Fuel Performance Improvement Program sponsored by the United States Department of Energy. Rods of different designs were tested. The reference design had solid, dished pellets and was unpressurized. The alternative designs were annular pellets and sphere-pac. Some of the rods with annular pellets were prepressurized, and some were not. During the ramp tests the rod power is controlled by a helium depressurization loop which causes a strictly linear power ramp versus time. The thermal output of the test rig is measured calorimetrically, the data immediately being recorded on a strip chart and later processed by a computer. Furthermore, elongation detectors permit the immediate recording of the rod length variation versus time. For some of the rods the thermal output went constant for a fraction of a minute after reaching a certain value, then continued to rise, while the helium depressurization continued to proceed linearly with time. For the duration of this plateau of the thermal output curve the slope of the elongation detector signal was significantly higher than before, but fell back to its original value after the plateau. This observation was made only for the reference rods. None of the annular rods, with or without prepressurization, nor the sphere-pac rods, showed the effect. When observed, the effect occurred at about 40 kw/m. The effect is attributed to fission gas release rapidly being enhanced by thermal feedback. The increase in stored energy associated with the temperature rise in the fuel causes the delay in thermal output. The larger available internal volume and/or the prepressurization of the annular rods, and the lack of a distinct fuel-clad gap for the sphere-pac rods prevented the effect from occurring in those other

    A selective sweep is the result of strong positive selection driving newly occurring or standing genetic variants to fixation, and can dramatically alter the pattern and distribution of allelic diversity in a population. Population-level sequencing data have enabled discoveries of selective sweeps associated with genes involved in recent adaptations in many species. In contrast, much debate but little evidence addresses whether "selfish" genes are capable of fixation-thereby leaving signatures identical to classical selective sweeps-despite being neutral or deleterious to organismal fitness. We previously described R2d2, a large copy-number variant that causes nonrandom segregation of mouse Chromosome 2 in females due to meiotic drive. Here we show population-genetic data consistent with a selfish sweep driven by alleles of R2d2 with high copy number (R2d2(HC)) in natural populations. We replicate this finding in multiple closed breeding populations from six outbred backgrounds segregating for R2d2 alleles. We find that R2d2(HC) rapidly increases in frequency, and in most cases becomes fixed in significantly fewer generations than can be explained by genetic drift. R2d2(HC) is also associated with significantly reduced litter sizes in heterozygous mothers, making it a true selfish allele. Our data provide direct evidence of populations actively undergoing selfish sweeps, and demonstrate that meiotic drive can rapidly alter the genomic landscape in favor of mutations with neutral or even negative effects on overall Darwinian fitness. Further study will reveal the incidence of selfish sweeps, and will elucidate the relative contributions of selfish genes, adaptation and genetic drift to evolution. © The Author 2016.

  10. MiR-2 family regulates insect metamorphosis by controlling the juvenile hormone signaling pathway.

    Science.gov (United States)

    Lozano, Jesus; Montañez, Raúl; Belles, Xavier

    2015-03-24

    In 2009 we reported that depletion of Dicer-1, the enzyme that catalyzes the final step of miRNA biosynthesis, prevents metamorphosis in Blattella germanica. However, the precise regulatory roles of miRNAs in the process have remained elusive. In the present work, we have observed that Dicer-1 depletion results in an increase of mRNA levels of Krüppel homolog 1 (Kr-h1), a juvenile hormone-dependent transcription factor that represses metamorphosis, and that depletion of Kr-h1 expression in Dicer-1 knockdown individuals rescues metamorphosis. We have also found that the 3'UTR of Kr-h1 mRNA contains a functional binding site for miR-2 family miRNAs (for miR-2, miR-13a, and miR-13b). These data suggest that metamorphosis impairment caused by Dicer-1 and miRNA depletion is due to a deregulation of Kr-h1 expression and that this deregulation is derived from a deficiency of miR-2 miRNAs. We corroborated this by treating the last nymphal instar of B. germanica with an miR-2 inhibitor, which impaired metamorphosis, and by treating Dicer-1-depleted individuals with an miR-2 mimic to allow nymphal-to-adult metamorphosis to proceed. Taken together, the data indicate that miR-2 miRNAs scavenge Kr-h1 transcripts when the transition from nymph to adult should be taking place, thus crucially contributing to the correct culmination of metamorphosis.

    2015-04-01

    In recent years, a growing number of funding agencies and professional societies have issued policies calling for open access to research data. The Rolling Deck to Repository (R2R) program is working to ensure open access to the environmental sensor data routinely acquired by the U.S. academic research fleet. Currently 25 vessels deliver 7 terabytes of data to R2R each year, acquired from a suite of geophysical, oceanographic, meteorological, and navigational sensors on over 400 cruises worldwide. R2R is working to ensure these data are preserved in trusted repositories, discoverable via standard protocols, and adequately documented for reuse. R2R maintains a master catalog of cruises for the U.S. academic research fleet, currently holding essential documentation for over 3,800 expeditions including vessel and cruise identifiers, start/end dates and ports, project titles and funding awards, science parties, dataset inventories with instrument types and file formats, data quality assessments, and links to related content at other repositories. A Digital Object Identifier (DOI) is published for 1) each cruise, 2) each original field sensor dataset, 3) each post-field data product such as quality-controlled shiptrack navigation produced by the R2R program, and 4) each document such as a cruise report submitted by the science party. Scientists are linked to personal identifiers, such as the Open Researcher and Contributor ID (ORCID), where known. Using standard global identifiers such as DOIs and ORCIDs facilitates linking with journal publications and generation of citation metrics. Since its inception, the R2R program has worked in close collaboration with other data repositories in the development of shared semantics for oceanographic research. The R2R cruise catalog uses community-standard terms and definitions hosted by the NERC Vocabulary Server, and publishes ISO metadata records for each cruise that use community-standard profiles developed with the NOAA Data

    In this paper we consider a diffusion system with the Belousov-Zhabotinskii (BZ for short) chemical reaction. Following Brazhnik and Tyson [4] and Pérez-Muñuzuri et al. [45], who predicted V-shaped fronts theoretically and discovered V-shaped fronts by experiments respectively, we give a rigorous mathematical proof of their results. We establish the existence of V-shaped traveling fronts in R2 by constructing a proper supersolution and a subsolution. Furthermore, we establish the stability of the V-shaped front in R2.

    Machine learning methods and in particular random forests (RFs) are a promising alternative to standard single SNP analyses in genome-wide association studies (GWAS). RFs provide variable importance measures (VIMs) to rank SNPs according to their predictive power. However, in contrast to the established genome-wide significance threshold, no clear criteria exist to determine how many SNPs should be selected for downstream analyses. We propose a new variable selection approach, recurrent relative variable importance measure (r2VIM). Importance values are calculated relative to an observed minimal importance score for several runs of RF and only SNPs with large relative VIMs in all of the runs are selected as important. Evaluations on simulated GWAS data show that the new method controls the number of false-positives under the null hypothesis. Under a simple alternative hypothesis with several independent main effects it is only slightly less powerful than logistic regression. In an experimental GWAS data set, the same strong signal is identified while the approach selects none of the SNPs in an underpowered GWAS. The novel variable selection method r2VIM is a promising extension to standard RF for objectively selecting relevant SNPs in GWAS while controlling the number of false-positive results.

    Full Text Available Cellular phone is one of the most profitable industries in the world and especially in middle east regions. There is a growing competition among different firms in this market and the market share is exchanged very quickly depending on the features and equipments introduced. Customer satisfaction plays an important role on retaining present marker share or absorbing new customers. In this paper, we present an empirical study to measure the effects of different factors influencing customer satisfaction such as the effect of perceived expectations on perceived quality and the effect of perceived expectation on perceived value. The survey is performed among customers who live in Tehran, the capital city of Iran and it shows there are some meaningful and positive relationship between perceived expectations and other factors such as perceived quality and perceived value. There is also positive relationship between perceived quality and perceived value. perceived expectation and customer satisfaction.

    Maričić Branko R.

    2012-01-01

    Full Text Available Customer satisfaction is important in business management as a basis for long-term profitability of a single line of products and services and the company as a whole. Customer satisfaction in modern market conditions is characterized by a large number of alternatives that can satisfy the same need or desire of consumers, and are a prerequisite for the retention, loyalty, and positive verbal communication between companies and vendors on one hand and consumers on the other. Companies are investing more and more investment and management efforts in improving customer satisfaction. Improving customer satisfaction and its measurement involves the taking of appropriate marketing strategies and tactics, as well as corrective measures. This paper presents the well-known attempts to measure customers' satisfaction at the macro and micro level of marketing analysis. The index of consumer satisfaction is an important indicator of achieved quality and market performance of companies and can be measured on a micro and macro level. National customer satisfaction indexes are useful framework for analyzing the competitiveness of national economies, industries and individual companies and are used for a variety of other aspects of observation and analysis. Standardization of consumer satisfaction indexes in different countries allows comparability of the data, giving a new quality of analysis in the era of globalization and internationalization of business.

    2016-09-01

    Transcription factors R2R3MYB family have been associated with the control of secondary metabolites, development of structures, cold tolerance and response to biotic and abiotic stress, among others. In recent years, genomes of Rosaceae botanical family are available. Although this information has been used to study the karyotype evolution of these species from an ancestral genome, there are no studies that treat the evolution and diversity of gene families present in these species or in the botanical family. Here we present the first comparative study of the R2R3MYB subfamily of transcription factors in three species of Rosaceae family (Malus domestica, Prunus persica and Fragaria vesca). We described 186, 98 and 86 non-redundant gene models for apple, peach and strawberry, respectively. In this research, we analyzed the intron-exon structure and genomic distribution of R2R3MYB families mentioned above. The phylogenetic comparisons revealed putative functions of some R2R3MYB transcription factors. This analysis found 44 functional subgroups, seven of which were unique for Rosaceae. In addition, our results showed a highly collinearity among some genes revealing the existence of conserved gene models between the three species studied. Although some gene models in these species have been validated under several approaches, more research in the Rosaceae family is necessary to determine gene expression patterns in specific tissues and development stages to facilitate understanding of the regulatory and biochemical mechanism in this botanical family.

    This article introduces the importance of equivalence framing for understanding how satisfaction measures affect citizens’ evaluation of public services. Does a 90 percent satisfaction rate have a different effect than a logically equivalent 10 percent dissatisfaction rate? Two experiments were...... conducted on citizens’ evaluations of hospital services in a large, nationally representative sample of Danish citizens. Both experiments found that exposing citizens to a patient dissatisfaction measure led to more negative views of public service than exposing them to a logically equivalent satisfaction...... metric. There is some support for part of the shift in evaluations being caused by a negativity bias: dissatisfaction has a larger negative impact than satisfaction has a positive impact. Both professional experience at a hospital and prior exposure to satisfaction rates reduced the negative response...

  16. R2R Eventlogger: Community-wide Recording of Oceanographic Cruise Science Events

    Maffei, A. R.; Chandler, C. L.; Stolp, L.; Lerner, S.; Avery, J.; Thiel, T.

    2012-12-01

    Methods used by researchers to track science events during a science research cruise - and to note when and where these occur - varies widely. Handwritten notebooks, printed forms, watch-keeper logbooks, data-logging software, and customized software have all been employed. The quality of scientific results is affected by the consistency and care with which such events are recorded and integration of multi-cruise results is hampered because recording methods vary widely from cruise to cruise. The Rolling Deck to Repository (R2R) program has developed an Eventlogger system that will eventually be deployed on most vessels in the academic research fleet. It is based on the open software package called ELOG (http://midas.psi.ch/elog/) originally authored by Stefan Ritt and enhanced by our team. Lessons have been learned in its development and use on several research cruises. We have worked hard to find approaches that encourage cruise participants to use tools like the eventlogger. We examine these lessons and several eventlogger datasets from past cruises. We further describe how the R2R Science Eventlogger works in concert with the other R2R program elements to help coordinate research vessels into a coordinated mobile observing fleet. Making use of data collected on different research cruises is enabled by adopting common ways of describing science events, the science instruments employed, the data collected, etc. The use of controlled vocabularies and the practice of mapping these local vocabularies to accepted oceanographic community vocabularies helps to bind shipboard research events from different cruises into a more cohesive set of fleet-wide events that can be queried and examined in a cross-cruise manner. Examples of the use of the eventlogger during multi-cruise oceanographic research programs along with examples of resultant eventlogger data will be presented. Additionally we will highlight the importance of vocabulary use strategies to the success of the

    TNF-related apoptosis-inducing ligand receptor-2 (TRAIL-R2) is produced both by decidual and trophoblast cells during pregnancy and known to participate in apoptosis. In this study, we aimed to determine and to compare maternal serum and placental TRAIL-R2 levels in patients with placenta accreta, non-adherent placenta previa and in healthy pregnancies. We also aimed to analyze the association of placenta accreta with the occurrence of previous C-sections. A total of 82 pregnant women were enrolled in this case-control study (27 placenta accreta patients, 26 non-adherent placenta previa patients and 29 age-, and BMI-matched healthy, uncomplicated pregnant controls). TRAIL-R2 levels were studied in both maternal serum and placental tissue homogenates. Determining the best predictor(s) which discriminate placenta accreta was analyzed by multiple logistic regression analyses. Adjusted odds ratios and 95% confidence intervals were also calculated. Both placental and serum TRAIL-R2 levels were significantly lower in placenta accreta group (median 34.82 pg/mg and 19.85 pg/mL, respectively) when compared with both non-adherent placenta previa (median 39.24 pg/mg and 25.99 pg/mL, respectively) and the control groups (median 41.62 pg/mg and 25.87 pg/mL, respectively) (p Placental TRAIL-R2 levels and previous cesarean section were found to be significantly associated with placenta accreta (OR: 0.934 95% CI 0.883-0.987, p = 0.016 and OR:7.725 95% CI: 2.717-21.965, p Placental and serum TRAIL-R2 levels were positively correlated. Decreased levels of placental TRAIL-R2 and previous history of cesarean section were found to be significantly associated with placenta accreta, suggesting a possible role of apoptosis in abnormal trophoblast invasion.

  18. Improved R2* liver iron concentration assessment using a novel fuzzy c-mean clustering scheme

    International Nuclear Information System (INIS)

    Saiviroonporn, Pairash; Viprakasit, Vip; Krittayaphong, Rungroj

    2015-01-01

    In thalassemia patients, R2* liver iron concentration (LIC) measurement is a common clinical tool for assessing iron overload and for determining necessary chelator dose and evaluating its efficacy. Despite the importance of accurate LIC measurement, existing methods suffer from LIC variability, especially at the severe iron overload range due to inclusion of vessel parts in LIC calculation. In this study, we build upon previous Fuzzy C-Mean (FCM) clustering work to formulate a scheme with superior performance in segmenting vessel pixels from the parenchyma. Our method (MIX-FCM) combines our novel 2D-FCM with the existing 1D-FCM algorithm. This study further assessed possible optimal clustering parameters (OP scheme) and proposed a semi-automatic (SA) scheme for routine clinical application. Segmentation of liver parenchyma and vessels was performed on T2* images and their LIC maps in 196 studies from 147 thalassemia major patients. We used manual segmentation as the reference. 1D-FCM clustering was performed on the acquired image alone and 2D-FCM used both the acquired image and its LIC data. To execute the MIX-FCM method, the best outcome (OP-MIX-FCM) was selected from the aforementioned methods and was compared to the SA-MIX-FCM scheme. We used the percent value of the normalized interquartile range (nIQR) to its median to evaluate the variability of all methods. 2D-FCM clustering is more effective than 1D-FCM clustering at the severe overload range only, but inferior for other ranges (where 1D-FCM provides suitable results). This complementary performance between the two methods allows MIX-FCM to improve results for all ranges. OP-MIX-FCM clustering error was 2.1 ± 2.3 %, compared with 10.3 ± 9.9 % and 7.0 ± 11.9 % from 1D- and 2D-FCM clustering, respectively. SA-MIX-FCM result was comparable to OP-MIX-FCM result, with both schemes showing ability to decrease overall nIQR by approximately 30 %. Our proposed 2D-FCM algorithm is not as superior to 1D-FCM as

  19. Voltage-dependent modulation of cardiac ryanodine receptors (RyR2 by protamine.

    Directory of Open Access Journals (Sweden)

    Paula L Diaz-Sylvester

    Full Text Available It has been reported that protamine (>10 microg/ml blocks single skeletal RyR1 channels and inhibits RyR1-mediated Ca2+ release from sarcoplasmic reticulum microsomes. We extended these studies to cardiac RyR2 reconstituted into planar lipid bilayers. We found that protamine (0.02-20 microg/ml added to the cytosolic surface of fully activated RyR2 affected channel activity in a voltage-dependent manner. At membrane voltage (V(m; SR lumen-cytosol = 0 mV, protamine induced conductance transitions to several intermediate states (substates as well as full block of RyR2. At V(m>10 mV, the substate with the highest level of conductance was predominant. Increasing V(m from 0 to +80 mV, decreased the number of transitions and residence of the channel in this substate. The drop in current amplitude (full opening to substate had the same magnitude at 0 and +80 mV despite the approximately 3-fold increase in amplitude of the full opening. This is more similar to rectification of channel conductance induced by other polycations than to the action of selective conductance modifiers (ryanoids, imperatoxin. A distinctive effect of protamine (which might be shared with polylysines and histones but not with non-peptidic polycations is the activation of RyR2 in the presence of nanomolar cytosolic Ca2+ and millimolar Mg2+ levels. Our results suggest that RyRs would be subject to dual modulation (activation and block by polycationic domains of neighboring proteins via electrostatic interactions. Understanding these interactions could be important as such anomalies may be associated with the increased RyR2-mediated Ca2+ leak observed in cardiac diseases.

    We report the detection of a new radio recombination line (RRL) maser object toward the IRS2 source in the MonR2 ultracompact H II region. The continuum emission at 1.3 mm and 0.85 mm and the H30{alpha} and H26{alpha} lines were observed with the Submillimeter Array (SMA) at angular resolutions of {approx}0.''5-3''. The SMA observations show that the MonR2-IRS2 source is very compact and remains unresolved at spatial scales {<=}400 AU. Its continuum power spectrum at millimeter wavelengths is almost flat ({alpha} = -0.16, with S{sub {nu}}{proportional_to}{nu}{sup {alpha}}), indicating that this source is dominated by optically thin free-free emission. The H30{alpha} and H26{alpha} RRL emission is also compact and peaks toward the position of the MonR2-IRS2 source. The measured RRL profiles are double peaked with the H26{alpha} line showing a clear asymmetry in its spectrum. Since the derived line-to-continuum flux ratios ({approx}80 and 180 km s{sup -1} for H30{alpha} and H26{alpha}, respectively) exceed the LTE predictions, the RRLs toward MonR2-IRS2 are affected by maser amplification. The amplification factors are, however, smaller than those found toward the emission-line star MWC349A, indicating that MonR2-IRS2 is a weakly amplified maser. Radiative transfer modeling of the RRL emission toward this source shows that the RRL masers arise from a dense and collimated jet embedded in a cylindrical ionized wind, oriented nearly along the direction of the line of sight. High-angular resolution observations at submillimeter wavelengths are needed to unveil weakly amplified RRL masers in very young massive stars.

  1. Decommissioning of the Nuclear Reactors R2 and R2-0 at Studsvik, Sweden. General Data as called for under Article 37 of the Euratom Treaty

    International Nuclear Information System (INIS)

    2009-01-01

    This document describes the plans for decommissioning of the nuclear research and material test reactors R2 and R2-0, situated at the Studsvik site close to the city of Nykoeping, Sweden. The purpose of the document is to serve as information for the European Commission, and to fulfil the requirements of Article 37 of the Euratom Treaty. Studsvik is situated on the Baltic coast, about 20 km east of Nykoeping and 80 km southwest of Stockholm. The site comprises the reactors R2 and R2-0 and several facilities for material investigation and radioactive waste treatment and storage. The reactors were used for a number of different purposes from 1960 until June 2005, when they were shut down following a decision by the operator. Decommissioning of the reactor facility is planned to be completed in 2016 after dismantling and conditioning of radioactive parts and demolition of the facility. Solid and liquid radioactive wastes from the dismantling activities will be treated and stored on-site awaiting final disposal. The waste treatment facilities, which are situated in other buildings at the Studsvik site, are planned to continue operation during and after the decommissioning of the reactor facility. All nuclear fuel has been transferred to a separate storage facility and is being shipped to the US according to existing agreements. The objective of the planned dismantling activities is to achieve clearance of the facility to make it possible to either demolish the buildings or use them for other purposes. The operator has divided the planning for dismantling and demolition of the facility into three phases [1]: Dismantling 1, including primary system decontamination, dismantling of the reactors with systems in the reactor pool, draining, cleaning and temporary covering of the reactor pool. This phase has begun and is due to last till approximately December 2009. Dismantling 2, including dismantling of systems in the reactor facility, removal of equipment, radiological

    In this work we report the synthesis of polycrystalline samples of Bi 5 FeTi 3 O 15 and Bi 3 R 2 FeTi 3 O 15 new compounds with R=Nd, Sm, Gd, Dy, Ho and Yb. The materials were synthesized by the standard solid state reaction recipe from high purity (99.99%) powders. The structural characteristics of materials were analyzed by X-ray diffraction experiments. Rietveld refinement by the GSAS code was performed, taking the input data from the ICSD 74037 database. Results reveal that materials crystallized in orthorhombic single-phase structures and space group Fmm2. Measurements of polarization as a function of applied electric field were carried out using a Radiant Technology polarimeter. We determine the occurrence of hysteretic behaviors, which are characteristic of ferroelectric materials. The main values of remnant and coercive applied fields were observed for substitutions with Yb and Nd, which have the main atomic radii.

The determination of the local susceptibility tensor {chi(parallel to),chi(perpendicular)} provides a universal description of the field induced structures in the paramagnetic phase (2-270 K), whatever the field value (1-7 T) and direction. Comparison of the thermal variations of chi(parallel to) and chi(perpendicular) with calculations using the rare earth crystal field shows that exchange and dipolar interactions must be taken into account. We determine the molecular field tensor in each case and show that it can be strongly anisotropic.

    Scribes are increasingly being used in clinical practice despite a lack of high-quality evidence regarding their effects. Our objective was to evaluate the effect of medical scribes on physician satisfaction, patient satisfaction, and charting efficiency. We conducted a randomized controlled trial in which physicians in an academic family medicine clinic were randomized to 1 week with a scribe then 1 week without a scribe for the course of 1 year. Scribes drafted all relevant documentation, which was reviewed by the physician before attestation and signing. In encounters without a scribe, the physician performed all charting duties. Our outcomes were physician satisfaction, measured by a 5-item instrument that included physicians' perceptions of chart quality and chart accuracy; patient satisfaction, measured by a 6-item instrument; and charting efficiency, measured by time to chart close. Scribes improved all aspects of physician satisfaction, including overall satisfaction with clinic (OR = 10.75), having enough face time with patients (OR = 3.71), time spent charting (OR = 86.09), chart quality (OR = 7.25), and chart accuracy (OR = 4.61) (all P values patient satisfaction. Scribes increased the proportion of charts that were closed within 48 hours (OR =1.18, P =.028). To our knowledge, we have conducted the first randomized controlled trial of scribes. We found that scribes produced significant improvements in overall physician satisfaction, satisfaction with chart quality and accuracy, and charting efficiency without detracting from patient satisfaction. Scribes appear to be a promising strategy to improve health care efficiency and reduce physician burnout. © 2017 Annals of Family Medicine, Inc.

    Full Text Available This study aims to investigate, through the development and operationalized constructs of service quality, service charge, perceived value, and customer satisfaction; customersatisfaction and its determinants of the banking industry in Bangladesh. An exploratory factor analysis and structural equation modeling was used to analyze data. Measurement model and structural model indicate that service quality and fair service charge both havepositive direct impact on customer satisfaction in a mass service industry (i.e., banking industry. It was further observed that they also have indirect influence on customer satisfaction through perceive value, i.e. perceived value has mediating role betweenquality, charge fairness and satisfaction. Bank managers are recommended to formulate operations and marketing strategies that focus on desires of customers to enhance level of satisfaction.

  7. Determinants of customer satisfaction with service encounter

    Full Text Available Service encounters are the focal point of a customer’s perception of a service in terms of its quality, value and customer satisfaction. The paper researches the influence of the components of a service encounter on customer satisfaction. Among several factors that determine customer satisfaction the quality of service, which is related to the characteristics of service, plays an important role. However, a direct insight into the reasons that make a service encounter satisfactory or unsatisfactory is provided by the critical incident technique, where causes of dis/satisfaction differ primarily depending on whether they derive from interpersonal contact or from contact with technology. The evidence of service, which includes people, process and the physical evidence, plays a critical role in a customer’s dis/satisfaction. The influence of these elements cannot be observed separately; it must be observed in their interaction during the delivery of service and their strongest effect is achieved during face-to-face service encounters that have the characteristics of a theatre metaphor. Even though a high level of satisfaction may be achieved after the recovery of a service, enterprises should aim to conduct excellent service encounters right from the start.

    Thioredoxin reductase 2 (TrxR2) is a selenium (Se) containing protein. Se deficiency is associated with an endemic osteoarthropathy characterized by impaired cartilage formation. It is unclear whether TrxR2 have roles in cartilage function. We examined the effects of TrxR2 on chondrogenic ATDC5 cells through shRNA-mediated gene silencing of TrxR2. We demonstrated TrxR2 deficiencies could enhance chondrogenic differentiation and apoptosis of ATDC5 cells. TrxR2 deficiencies increased accumulation of cartilage glycosaminoglycans (GAGs) and mineralization. TrxR2 deficiencies also stimulated expression of extracellular (ECM) gene including Collagen II and Aggrecan. The enhanced chondrogenic properties were further confirmed by activation of Akt signaling which are required for chondrogenesis. In addition, TrxR2 deficiencies promoted chondrocyte proliferation through acceleration of cell cycle progression by increase in both S and G2/M phase cell distribution accompanied with induction of parathyroid hormone-related protein (PTHrP). Moreover, TrxR2 deficiencies induced chondrocyte death via apoptosis and increased cell sensitivity to exogenous oxidative stress. Furthermore, TrxR2 deficiencies induced emission of mitochondrial reactive oxygen species (ROS) without alteration of mitochondrial membrane potential and intracellular ATP content. Finally, treatment of TrxR2 deficiency cells with N-acetylcysteine (NAC) inhibited mitochondrial ROS production and chondrocyte apoptosis. NAC also prevented chondrogenic differentiation of TrxR2 deficiency cells by suppression of ECM gene expression, GAGs accumulation and mineralization, as well as attenuation of Akt signaling. Thus, TrxR2-mediated mitochondrial integrity is indispensable for chondrogenic differentiation of ATDC5 cells. TrxR2 deficiency-induced impaired proliferation and death of chondrocytes may be the pathological mechanism of the osteoarthropathy due to Se deficiency. Notably, this study also uncover the roles of

    Products are now developed based on what customers desire, and thus attractive quality creation has become crucial. In studies on customer satisfaction, methods for analyzing quality attributes and enhancing customer satisfaction have been proposed to facilitate product development. Although substantial studies have performed to assess the impact of the attributes on customer satisfaction, little research has been conducted that quantitatively calculate the odds of customer satisfaction for the Kano classification, fitting a nonlinear relationship between attribute-level performance and customer satisfaction. In the present study, the odds of customer satisfaction were determined to identify the classification of quality attributes, and took customer psychology into account to suggest how decision-makers should prioritize the allocation of resources. A novel method for quantitatively assessing quality attributes was proposed to determine classification criteria and fit the nonlinear relationship between quality attributes and customer satisfaction. Subsequently, a case study was conducted on bicycle user satisfaction to verify the novel method. The concept of customer satisfaction odds was integrated with the value function from prospect theory to understand quality attributes. The results of this study can serve as a reference for product designers to create attractive quality attributes in their products and thus enhance customer satisfaction.

    Monitoring and managing customers' satisfaction are key features to benefit from today's competitive environment. In higher education context, only a few studies are available on satisfaction and loyalty of the main customers who are the students, which signifies the need to investigate the field more thoroughly. The aim of this research is to measure the strength of determinants of students' satisfaction and the importance of antecedents in students' satisfaction and loyalty in Denmark. Our research model is the modification of European Performance Satisfaction Index (EPSI), which takes the university's image direct effects on students' expectations into account from students' perspective. The structural equation model of student satisfaction and loyalty has been evaluated using partial least square path modelling. Our findings confirm that the EPSI framework is applicable on student satisfaction and loyalty among Danish universities. We show that all the relationships among variables of the research model are significant except the relationship between quality of software and students' loyalty. Results further verify the significance of antecedents in students' satisfaction and loyalty at Danish universities; the university image and student satisfaction are the antecedents of student loyalty with a significant direct effect, while perceived value, quality of hardware, quality of software, expectations, and university image are antecedents of student satisfaction. Eventually, our findings may be of an inspiration to maintain and improve students' experiences during their study at the university. Dedicating resources to identified important factors from students' perception enable universities to attract more students, make them highly satisfied and loyal.

    本文以社会交换的理论和价值观领导理论为基础,探讨了CEO变革型领导行为及其价值观对中层管理者工作绩效和工作满意度的跨层次影响。研究结果表明,CEO变革型领导行为有助于提升中层管理者的工作绩效和工作满意度,而组织支持知觉则在其中起着部分中介的作用。同时,CEO价值观对CEO变革型领导行为与组织支持知觉之间的关系具有调节的作用。木文的研究成果有利于进一步完善变革型领导理论,对企业实践也有一定的启示意义。%This study mainly focuses on the effect of transformational leadership behavior on the job perfonnance and job satisfaction of middle-level managers. Using the approach of multi-level research among leaders and middle-level managers, we found that CEO transformational leadership behavior has a significant and positive effect on the job performance and job satisfaction of middle-level managers. Moreover, based on the social exchange theory and the value leadership theory, we further discuss the mediating effect of the middlelevel manager's organizational support perception on the relationship between CEO transformational leadership behavior and middle-level manager's job performance and job satisfaction. We also discuss the CEO values' mediating effect on the relationship between CEO transformational leadership behavior and organizational support perception. Our results show that CEO transformational behavior helps to improve the job performance and job satisfaction of middle-level managers and that organizational support perception plays a partial mediating effect. This finding shows that transformational leadership behavior has a direct effect on the job performance and job satisfaction of middle-level managers through strengthening their organizational support perception. Moreover, CEO's values have a moderating effect on their transformational leadership behavior: altruistic values strengthen

    Tributyltin (TBT), which has been widely used as an antifouling agent in paints, is a common environmental pollutant. Although the toxicity of high-dose TBT has been extensively reported, the effects of low concentrations of TBT are relatively less well studied. We have previously reported that low-concentration TBT decreases ?-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-type glutamate receptor subunit 2 (GluR2) expression in cortical neurons and enhances neuronal vulnerability ...

    2013-04-01

    The Rolling Deck to Repository (R2R) program is developing infrastructure to ensure the underway sensor data from U.S. academic oceanographic research vessels are routinely and consistently documented, preserved in long-term archives, and disseminated to the science community. The entire R2R Catalog is published online as a Linked Data collection, making it easily accessible to encourage discovery and integration with data at other repositories. We are developing the R2R Linked Data collection with specific goals in mind: 1.) We facilitate data access and reuse by publishing the richest possible collection of resources to describe vessels, cruises, instruments, and datasets from the U.S. academic fleet, including data quality assessment results and clean trackline navigation; 2.) We facilitate data citation through the entire lifecycle from field acquisition to shoreside archiving to journal articles and global syntheses, by publishing Digital Object Identifiers (DOIs) for datasets and encoding them directly into our Linked Data resources; and 3.) We facilitate federation with other repositories such as the Biological and Chemical Oceanography Data Management Office (BCO-DMO), InterRidge Vents Database, and Index to Marine and Lacustrine Geological Samples (IMLGS), by reciprocal linking between RDF resources and supporting the RDF Query Language. R2R participates in the Ocean Data Interoperability Platform (ODIP), a joint European-U.S.-Australian partnership to facilitate the sharing of data and documentation across international borders. We publish our controlled vocabularies as a Simple Knowledge Organization System (SKOS) concept collection, and are working toward alignment with SeaDataNet and other community-standard terms using the NERC Vocabulary Server (NVS). http://rvdata.us/

  14. Job satisfaction among control room operators of electrical systems.

    Macaia, Amanda A Silva; Marqueze, Elaine C; Rotenberg, Lúcia; Fischer, Frida Marina; Moreno, Claudia R C

    2012-01-01

    Shift workers from control centers of electrical systems are a group that has received little attention in Brazil. This study aimed to compare workers' job satisfaction at five control centers of a Brazilian company electrical system, and according to their job titles. The Organization Satisfaction Index (OSI) questionnaire to assess job satisfaction was used. ANOVA was used to compare OSI means, according to job title and control center. The results showed that there is no difference in job satisfaction among job titles, but a significant difference was found according to the control center. A single organizational culture cannot be applied to several branches. It is required to implement actions that would result in job satisfaction improvements among workers of all studied control rooms centers. The high level of education of operators working in all centers might have contributed to the similar values of perceived satisfaction among distinct job titles.

  15. Maslow and the motivation hierarchy: measuring satisfaction of the needs.

    Taormina, Robert J; Gao, Jennifer H

    2013-01-01

    For each of the 5 needs in Maslow's motivational hierarchy (physiological, safety-security, belongingness, esteem, and self-actualization), operational definitions were developed from Maslow's theory of motivation. New measures were created based on the operational definitions (1) to assess the satisfaction of each need, (2) to assess their expected correlations (a) with each of the other needs and (b) with four social and personality measures (i.e., family support, traditional values, anxiety/worry, and life satisfaction), and (3) to test the ability of the satisfaction level of each need to statistically predict the satisfaction level of the next higher-level need. Psychometric tests of the scales conducted on questionnaire results from 386 adult respondents from the general population lent strong support for the validity and reliability of all 5 needs measures. Significant positive correlations among the scales were also found; that is, the more each lower-level need was satisfied, the more the next higher-level need was satisfied. Additionally, as predicted, family support, traditional values, and life satisfaction had significant positive correlations with the satisfaction of all 5 needs, and the anxiety/worry facet of neuroticism had significant negative correlations with the satisfaction of all the needs. Multiple regression analyses revealed that the satisfaction of each higher-level need was statistically predicted by the satisfaction of the need immediately below it in the hierarchy, as expected from Maslow's theory.

    High performance resistive magnet technology was used to develop a design for a compact, low cost version of the fusion engineering device FED. We refer to this design as FED-R2, for FED-resistive magnet design 2 to distinguish it from the larger resistive magnet design for FED which uses demountable coils (FED-R1). The main objectives of FED-R2 are: (1) to demonstrate reliable, quasi-steady state (long pulse, high duty factor) operation with Q/sub p/ approx. 5; (2) to demonstrate Q/sub p/ > 5 operation for a limited number of pulses; (3) to provide high neutron flux for irradiation of nuclear test modules with a total area greater tha 20m 2 ; (4) to utilize steady-state RF current drive if this option appears promising. Based upon the costing codes at the Fusion Engineering Design Center and upon TFTR costs, the estimated direct costs of FED-R2 would be on the range 380 to 460M, a factor of about 2 below that of the baseline FED design

    Pyrochlore R2B2O7 where R3 + stands for rear-earth ion and B4 + for a nonmagnetic cation such as Sn4 +or Ti4 +consist of an important family of geometrically frustrated magnets, which have been the focus of extensive investigations over last decades. To further enlarge the R2B2O7, we have chosen to stabilize the Pt-based cubic pyrochlores under HPHT conditions for two reasons: (1) Pt4 + is in a low-spin state which ionic radius is located in between Ti4 + (0.605\\x85) and Sn4 + (0.69\\x85), and (2) Pt4 + has a spatially much more extended 5d orbitals and thus enhanced Pt 5d-O 2p hybridizations that might modify the local anisotropic exchange interactions. Such an effect has never been taken into account in the previous studies. In this work, we will present the detailed characterizations on the pyrochlores R2Pt2O7 obtained under HPHT conditions.

    The cash crops grown in an agro-climatic region are prone to infection by various fungal pathogens. The use of chemical fungicides over the years has resulted in emergence of resistant fungal strains, thereby necessitating the development of effective and environmental friendly alternatives. The natural antagonistic interactions among different microbial populations have been exploited as an eco-friendly approach for controlling fungal pathogens resistant to synthetic chemicals. Morphologically distinct bacterial cultures (150), isolated from rhizospheric soils of wheat, rice, onion and tomato plants were screened for their antifungal potential against seven phytopathogenic fungi prevalent in the State of Punjab (India). The bacterial isolate R2, identified as Bacillus vallismortis, supported more than 50% inhibition of different phytopathogenic fungi (Alternaria alternata, Rhizoctonia oryzae, Fusarium oxysporum, Fusarium moniliforme, Colletotrichum sp, Helminthosporium sp and Magnaporthe grisea) in dual culture plate assay. The thin layer chromatography based bio-autography of acid-precipitated biomolecules (APB) indicated the presence of more than one type of antifungal molecule, as evidenced from zones of inhibition against the respective fungal pathogen. The initial analytical studies indicated the presence of surfactin, iturin A and fengycin-like compounds in APB. The antifungal activity of whole cells and APB of isolate R2 was evaluated by light and scanning electron microscopy. The wheat grains treated with APB and exposed to spores of A. alternata showed resistance to the development of black point disease, thereby indicating the potential application of R2 and its biomolecules at field scale level.

    Brain iron accumulates during aging and has been associated with neurodegenerative disorders including Alzheimer's disease. Magnetic resonance (MR)-based R2* mapping enables the in vivo detection of iron content in brain tissue. We investigated if during normal brain aging iron load relates to cognitive impairment in region-specific patterns in a community-dwelling cohort of 336 healthy, middle aged, and older adults from the Austrian Stroke Prevention Family Study. MR imaging and R2* mapping in the basal ganglia and neocortex were done at 3T. Comprehensive neuropsychological testing assessed memory, executive function, and psychomotor speed. We found the highest iron concentration in the globus pallidus, and pallidal and putaminal iron was significantly and inversely associated with cognitive performance in all cognitive domains, except memory. These associations were iron load dependent. Vascular brain lesions and brain volume did not mediate the relationship between iron and cognitive performance. We conclude that higher R2*-determined iron in the basal ganglia correlates with cognitive impairment during brain aging independent of concomitant brain abnormalities. The prognostic significance of this finding needs to be determined. Copyright © 2015 Elsevier Inc. All rights reserved.

    Research purpose: To examine the relationships between extrinsic motivation, job satisfaction and life satisfaction amongst employees in a public organisation. Motivation for the study: Labour strife is an endemic phenomenon in South Africa’s public sector as evidenced by the high incidences of industrial action and labour turnover. This study contributes to this subject by identifying the extrinsic factors that could be optimised with a view to enhancing job and life satisfaction amongst government employees. Research approach, design and method: The study used the quantitative research survey approach: a questionnaire was administered to 246 employees in a South African public organisation. Extrinsic motivation factors were identified using principal components analysis. Mean score ranking was used to compare the relative importance of all factors. The conceptual framework was tested using Spearman’s rank correlation analysis and linear regression analysis. Main findings: Statistically significant relationships were observed between job satisfaction and four extrinsic motivation factors: remuneration, quality of work life, supervision and teamwork. The relationship with promotion was insignificant, but a statistically significant relationship was established with life satisfaction. Practical/managerial implications: The findings may be used to implement strategies for enhancing employee performance and industrial relations within public organisations. Contribution/value-add: The study provides evidence of the interplay between extrinsic motivation, job satisfaction and life satisfaction for public servants in developing countries.

    Research purpose: The aim of the study was to investigate the relationship between employee satisfaction and life satisfaction amongst university academics in South Africa. Motivation for the study: The study occupies the gap in literature focusing on the interaction between employee satisfaction and life satisfaction amongst South African university academics. Research design, approach and method: A three-section survey questionnaire was administered to 273 academics recruited from three universities in Gauteng, South Africa. After a confirmatory factor analysis, hypotheses were tested using a combination of Kendall’s tau correlation coefficient and regression analysis. Main findings: Correlation tests revealed strong positive relationships between life satisfaction and three factors: workplace flexibility, skills utilisation and autonomy. Regression analysis showed that workplace flexibility, skills utilisation and autonomy were statistically significant. Practical/managerial implications: Research findings could expedite the generation of strategies for meeting the employment needs and expectations of university academics, thereby reducing the shortage of university academics in South Africa. Contributions/value-add: The conceptual framework proposed in this study is a useful tool for conceptualising the relationship between employee satisfaction and life satisfaction in the higher education environment.

    The Birth Satisfaction Scale - Revised (BSS-R) is a valid and reliable scale designed to assess women's experiences of labour and childbirth. To assess factor structure, validity, and reliability of the Turkish Birth Satisfaction Scale - Revised (T-BSS-R) using data collected from a Turkish population. Istanbul Ministry of Health Zeynep Kamil Women's and Children's Training and Research Hospital. A convenience sample of healthy child-bearing women (n = 120) who had experienced a spontaneous vertex delivery at full term. A survey was conducted post backtranslating the T-BSS-R, with survey data analysed using confirmatory factor analysis. Factor modelling found three subscales embedded in the T-BSS-R, which indicated a good model fit, χ 2 = 44.67, CFI = .94; RMSEA = .057; SRMR = .075. A Chi-square value of 1.33 also indicated a good fit. Means for the T-BSS-R subdimensions (1) Stress Experienced (T-BSS-SE-R) = 6.86 ± 3.10, (2) Women's Attributes (T-BSS-WA-R) = 2.84 ± 1.89, (3) Quality of Care (T-BSS-QC-R) = 10.69 ± 3.19 and total scale = 20.39 ± 5.98. The Cronbach alpha coefficient for total scale = 0.71 and for subdimensions T-BSS-SE-R = 0.55, T-BSS-WA-R = 0.44 and T-BSS-QC-R = -0.74. Data analysis determined that the T-BSS-R is a valid and reliable instrument to measure birth satisfaction in a population of Turkish women.

    As a continuing effort to enhance the quality of palliative care for the dying, this study examined (1) the prevalence of spirituality among hospice interdisciplinary team (IDT) members; (2) whether spirituality is related to job satisfaction; and (3) the structural path relationships among four variables: spiritual belief, integration of spirituality at work, self actualization and job satisfaction. The study surveyed 215 hospice IDT members who completed the Jarel Spiritual Well-Being Scale, the Chamiec-Case Spirituality Integration and Job Satisfaction Scales. Multiple regression and structural path modeling methods were applied to explain the path relationships involving all four variables. The IDT members surveyed were: nurses, 46.4%; home health aids, 24.9%; social workers, 17.4%; chaplains, 4.2%; physicians, 2.3%; and other, 4.8%. Ninety-eight percent of the respondents viewed themselves as having spiritual well-being. On a 0-100 scale, IDT staff reported high spiritual belief (mean = 89.4) and they were self-actualizing (mean = 82.6). Most reported high job satisfaction (mean = 79.3) and spiritual integration (mean = 67.9). In multiple regression, spirituality, integration and self-actualization explained 22% of the variation in job satisfaction (R = 0.48; adjusted R(2) = 0.218; df = 3,175; F = 17.2; p = 0.001). Structural path models revealed that job satisfaction is more likely to be realized by a model that transforms one's spirituality into processes of integrating spirituality at work and self actualization (chi(2) = 0.614; df = 1; p = 0.433) than a model that establishes a direct path from spirituality to job satisfaction (chi(2) = 1.65; df = 1; p = 0.199). Hospice IDT member's integration of their spirituality at work and greater self actualization significantly improve job satisfaction.

  8. A R2R3-MYB transcription factor from Epimedium sagittatum regulates the flavonoid biosynthetic pathway.

    Wenjun Huang

    Full Text Available Herba epimedii (Epimedium, a traditional Chinese medicine, has been widely used as a kidney tonic and antirheumatic medicine for thousands of years. The bioactive components in herba epimedii are mainly prenylated flavonol glycosides, end-products of the flavonoid pathway. Epimedium species are also used as garden plants due to the colorful flowers and leaves. Many R2R3-MYB transcription factors (TFs have been identified to regulate the flavonoid and anthocyanin biosynthetic pathways. However, little is known about the R2R3-MYB TFs involved in regulation of the flavonoid pathway in Epimedium. Here, we reported the isolation and functional characterization of the first R2R3-MYB TF (EsMYBA1 from Epimedium sagittatum (Sieb. Et Zucc. Maxim. Conserved domains and phylogenetic analysis showed that EsMYBA1 belonged to the subgroup 6 clade (anthocyanin-related MYB clade of R2R3-MYB family, which includes Arabidopsis AtPAP1, apple MdMYB10 and legume MtLAP1. EsMYBA1 was preferentially expressed in leaves, especially in red leaves that contain higher content of anthocyanin. Alternative splicing of EsMYBA1 resulted in three transcripts and two of them encoded a MYB-related protein. Yeast two-hybrid and transient luciferase expression assay showed that EsMYBA1 can interact with several bHLH regulators of the flavonoid pathway and activate the promoters of dihydroflavonol 4-reductase (DFR and anthocyanidin synthase (ANS. In both transgenic tobacco and Arabidopsis, overexpression of EsMYBA1 induced strong anthocyanin accumulation in reproductive and/or vegetative tissues via up-regulation of the main flavonoid-related genes. Furthermore, transient expression of EsMYBA1 in E. sagittatum leaves by Agrobacterium infiltration also induced anthocyanin accumulation in the wounded area. This first functional characterization of R2R3-MYB TFs in Epimedium species will promote further studies of the flavonoid biosynthesis and regulation in medicinal plants.

Yeast two-hybrid and transient luciferase expression assay showed that EsMYBA1 can interact with several bHLH regulators of the flavonoid pathway and activate the promoters of dihydroflavonol 4-reductase (DFR) and anthocyanidin synthase (ANS). In both transgenic tobacco and Arabidopsis, overexpression of EsMYBA1 induced strong anthocyanin accumulation in reproductive and/or vegetative tissues via up-regulation of the main flavonoid-related genes. Furthermore, transient expression of EsMYBA1 in E. sagittatum leaves by Agrobacterium infiltration also induced anthocyanin accumulation in the wounded area. This first functional characterization of R2R3-MYB TFs in Epimedium species will promote further studies of the flavonoid biosynthesis and regulation in medicinal plants.

    The NSF-funded Rolling Deck to Repository (R2R) project envisions the academic research fleet as an integrated global observing system, with routine “underway” sensor data flowing directly from research vessels to a central shore-side repository. It is a complex endeavor involving many stakeholders - technicians at sea, data managers on shore, ship schedulers, clearance officers, funding agencies, National Data Centers, data synthesis projects, the science community, and the public - working toward a common goal of acquiring, documenting, archiving, evaluating, and disseminating high-quality scientific data. The technical design for R2R is guided by several key principles: 1) The data pipeline is modular, so that initial stages (e.g. inventory and review of data shipments, posting of catalog records and track maps) may proceed routinely for every cruise, while later stages (e.g. quality assessment and production of file-level metadata) may proceed at different rates for different data types; 2) Cruise documentation (e.g. sailing orders, review/release of data inventories, vessel profiles) is gathered primarily via an authenticated Web portal, linked with the UNOLS scheduling database to synchronize vocabularies and eliminate redundancies; and 3) Every data set will be documented and delivered to the appropriate National Data Center for long-term archiving and dissemination after proprietary holds are cleared, while R2R maintains a master cruise catalog that links all the data sets together. This design accommodates the diversity of instrument types, data volumes, and shipment schedules among fleet operators. During its pilot development period, R2R has solicited feedback at community workshops, UNOLS meetings, and conference presentations, including fleet-wide surveys of current practices and instrument inventories. Several vessel operators began submitting cruise data and documentation during the pilot, providing a test bed for database development and Web

  11. Decommissioning of the Nuclear Reactors R2 and R2-0 at Studsvik, Sweden. General Data as called for under Article 37 of the Euratom Treaty

    Energy Technology Data Exchange (ETDEWEB)

    2009-01-15

    This document describes the plans for decommissioning of the nuclear research and material test reactors R2 and R2-0, situated at the Studsvik site close to the city of Nykoeping, Sweden. The purpose of the document is to serve as information for the European Commission, and to fulfil the requirements of Article 37 of the Euratom Treaty. Studsvik is situated on the Baltic coast, about 20 km east of Nykoeping and 80 km southwest of Stockholm. The site comprises the reactors R2 and R2-0 and several facilities for material investigation and radioactive waste treatment and storage. The reactors were used for a number of different purposes from 1960 until June 2005, when they were shut down following a decision by the operator. Decommissioning of the reactor facility is planned to be completed in 2016 after dismantling and conditioning of radioactive parts and demolition of the facility. Solid and liquid radioactive wastes from the dismantling activities will be treated and stored on-site awaiting final disposal. The waste treatment facilities, which are situated in other buildings at the Studsvik site, are planned to continue operation during and after the decommissioning of the reactor facility. All nuclear fuel has been transferred to a separate storage facility and is being shipped to the US according to existing agreements. The objective of the planned dismantling activities is to achieve clearance of the facility to make it possible to either demolish the buildings or use them for other purposes. The operator has divided the planning for dismantling and demolition of the facility into three phases [1]: Dismantling 1, including primary system decontamination, dismantling of the reactors with systems in the reactor pool, draining, cleaning and temporary covering of the reactor pool. This phase has begun and is due to last till approximately December 2009. Dismantling 2, including dismantling of systems in the reactor facility, removal of equipment, radiological

    2012-01-01

    This paper analyzes consumer satisfaction in the energy sector in Kenya to assess the quality and level of service delivery. By use of the European Consumer Satisfaction Index (ECSI), the paper estimates consumer satisfaction in biomass, petroleum, electricity and renewable energy subsectors. The findings are that consumer satisfaction is highest in the renewable energy sub sector at 74.7% followed by petroleum at 62.8%. The electricity sub sector has the lowest consumer satisfaction of 53.06%. Further, it is found that the image of renewable energy providers is also the highest at 72.5% followed by that of petroleum companies at 63.1%. In the electricity sub sector, perceived value scored the highest at 64.2%. The paper concludes that image of a service provider, loyalty of consumers, consumer expectations, perceived value, perceived quality and the way complains are handled are very important factors that determine consumer satisfaction levels. It is recommended that for monitoring and evaluation purposes in the performance of the energy sector, the Energy RegulatoryCommission(ERC) could use the consumer satisfaction index level to evaluate whether the regulatory policies and their implementation are bearing fruit where a high index would be associated with good performance and vice versa. - Highlights: ► The paper estimates consumer satisfaction in biomass, petroleum, electricity and renewable energy subsectors. ► Consumer satisfaction is highest in the renewable energy sub sector at 74.7%. ► The electricity sub sector has the lowest consumer satisfaction of 53.06%. ► Image of renewable energy providers is also the highest at 72.5%. ► Factors explaining consumer satisfaction are; Image, consumers’ loyalty, expectations, perceived value, and perceived quality.

  16. Development of a simple measurement method for GluR2 protein expression as an index of neuronal vulnerability

    Full Text Available In vitro estimating strategies for potential neurotoxicity are required to screen multiple substances. In a previous study, we showed that exposure to low-concentrations of some chemicals, such as organotin, decreased the expression of GluR2 protein, which is a subunit of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA-type glutamate receptors, and led to neuronal vulnerability. This result suggested that GluR2 decreases as an index of neuronal cell sensitivity and vulnerability to various toxic insults. Accordingly, we developed a versatile method that is a large scale determination of GluR2 protein expression in the presence of environmental chemicals by means of AlphaLISA technology. Various analytical conditions were optimized, and then GluR2 protein amount was measured by the method using AlphaLISA. The GluR2 amounts were strongly correlated with that of measured by western blotting, which is currently used to determine GluR2 expression. An ideal standard curve could be written with the authentic GluR2 protein from 0 ng to 100 ng. Subsequently, twenty environmental chemicals were screened and nitenpyram was identified as a chemical which lead to decrease in GluR2 protein expression. This assay may provide a tool for detecting neurotoxic chemicals according to decreases in GluR2 protein expression.

    R-2-hydroxyglutarate (R-2HG), produced at high levels by mutant isocitrate dehydrogenase 1/2 (IDH1/2) enzymes, was reported as an oncometabolite. We show here that R-2HG also exerts a broad anti-leukemic activity in vitro and in vivo by inhibiting leukemia cell proliferation/viability and by promoting cell-cycle arrest and apoptosis. Mechanistically, R-2HG inhibits fat mass and obesity-associated protein (FTO) activity, thereby increasing global N 6 -methyladenosine (m 6 A) RNA modification in R-2HG-sensitive leukemia cells, which in turn decreases the stability of MYC/CEBPA transcripts, leading to the suppression of relevant pathways. Ectopically expressed mutant IDH1 and S-2HG recapitulate the effects of R-2HG. High levels of FTO sensitize leukemic cells to R-2HG, whereas hyperactivation of MYC signaling confers resistance that can be reversed by the inhibition of MYC signaling. R-2HG also displays anti-tumor activity in glioma. Collectively, while R-2HG accumulated in IDH1/2 mutant cancers contributes to cancer initiation, our work demonstrates anti-tumor effects of 2HG in inhibiting proliferation/survival of FTO-high cancer cells via targeting FTO/m 6 A/MYC/CEBPA signaling.

    Full Text Available Abstract Background Primary care teams' job satisfaction is an important issue in quality of care. The purpose of our study was to evaluate the job satisfaction of general practitioners (GPs and non-physician staff and to explore the elements that may impact on overall job satisfaction for GPs and non-physician staff separately. Methods The study was based on data from the European Practice Assessment and used an observational design. Job satisfaction was measured with the 10-items Warr-Cook-Wall questionnaire with 7-point-Likert scales. Job satisfaction of GPs and non-physician staff was compared and impact on overall job satisfaction was analysed with stepwise linear regression analyses for both samples separately. Results The study population consisted of 2878 non-physician staff (mean age: 38 years and 676 GPs (mean age: 50 years. The actual mean working time per week of GPs was 50.0 hours and of practice staff 26.0 hours. Both were satisfied with colleagues and fellow workers (mean = 5.99 and mean = 6.18 respectively and mostly dissatisfied with their income (mean = 4.40 and mean = 4.79 respectively. For GPs the opportunity to use their abilities (β = 0.638 and for non-physician staff recognition for their work (β = 0.691 showed the highest scores of explained variance (R2 = 0.406 and R2 = 0.477 respectively regarding overall job satisfaction. Conclusions Non-physician staff evaluate their job satisfaction higher than GPs except recognition for work. Job satisfaction of members of primary care teams is important because poor satisfaction is associated with suboptimal healthcare delivery, poor clinical outcomes and higher turnover of staff.

    2013-01-01

    We studied the relationship between perceived social image and life satisfaction in four different cultural groups. One-hundred nine Indian (63 females, 46 males), 67 Pakistani/Bangladeshi (36 females, 31 males), 76 White British (43 females, 33 males), and 94 European Americans (43 females, 48 males) completed measures on the cultural importance of social image, positive and negative emotions, academic achievement, and perceived social image. Indian and Pakistani/Bangladeshi participants valued social image more than White British and European-American participants. Consistent with this value difference, a positive perceived social image predicted life satisfaction among Indian and Pakistani/Bangladeshi participants only. For these participants, perceived social image predicted life satisfaction above and beyond the effects of emotions and academic achievement. Academic achievement only predicted life satisfaction among White British and European Americans. Emotions were significant predictors of life satisfaction for all participants.

    Full Text Available Background and Purpose: Shiraz University of Medical Sciences as one of the oldest and largest universities of medicine in Iran with 50 years history has more than 450 faculty members and 5000 students. This study is an attempt to find out the level of job satisfaction among Shiraz University ofMedical Sciences’ faculty members.Methods: In midterm of 2003-2004, data on job satisfaction level among 404 faculty members from all schools of Shiraz University of Medical Sciences were collected. The translation of Spector’s job satisfaction score was used including 34 questions in 9 items of job satisfaction and each one based on Likert’s Scale with score an of 1-5. A question related to overall job satisfaction of faculty members was added.Results: Of all faculties,, 252 responded to the questionnaire and 70.1% expressed satisfaction in response the added question. The mean scores of job satisfaction in items of coworkers, work nature, supervision, management methods, academic relations, promotion, salary and suitable benefits were3.771, 3.265, 2.557, 2.454, 2.395, and 2.376 out of 5 respectively (F=223.8, p=0.0001. In the promotion item, the satisfaction of female faculty was lower than male subjects. The level of job satisfaction was not different between clinical faculty members of Medical School with or without private activity. The results of linear regression analysis between the items of job satisfaction revealed that reimbursement and fringe benefits could predict the overall job satisfaction (r2=0.70, p<0.01.Conclusion: As a whole, the faculty members of the university were satisfied with their jobs, but a correction in reimbursement, benefits and promotion regulations especially in lower academic ranks is needed to improve the level of job satisfaction in this group.Key words: JOB SATISFACTION, FACULTY MEMBER, BASIC AND CLINICAL DEPARTMENTS, FULLTIME, PART-TIME

    Based on emotional contagion theory and the value-profit chain literatures, the present study posits a number of hypotheses that show how managers in the small store, small number of employees retail context may affect store employees, customers, and potentially store performance. With data from 306 store managers, 1,615 store customer-contact employees, and 57,656 customers of a single retail chain, the authors examined relationships among store manager job satisfaction and job performance, store customer-contact employee job satisfaction and job performance, customer satisfaction with the retailer, and a customer-spending-based store performance metric (customer spending growth over a 2-year period). Via path analysis, several hypothesized direct and interaction relations among these constructs are supported. The results suggest implications for academic researchers and retail managers.

    To determine the perceived quality variables related to satisfaction and to identify the influence of sociodemographic factors on user satisfaction with hospital emergencies. A telephone survey was conducted with a specifically designed questionnaire for use in a sample of 3,600 users of hospital emergency services in nine public hospitals in 2008 and 2009. The adjusted model including all perceived quality and sociodemographic variables explained 47.1% of the variance (adjusted R(2)). Of all the independent variables included, only eight were significant in predicting the level of patient satisfaction. These variables were related to the patient's opinion of the relationship with medical staff (p = 0.041), nurses' and porters' professionalism (p = 0.010 and 0.022), infrastructure (cleanliness and comfort) (p = 0.033 and 0.008), information received at discharge (p = 0.000), waiting time in the emergency department (p = 0.000) and the perception of treatment-diagnosis without failure (p = 0.028). The variables influencing emergency patients' satisfaction were determined, allowing areas where corrective action could be introduced to be identified. In addition, possible confounding factors that should be controlled for when comparing results among distinct hospitals were identified. The emergency satisfaction questionnaire is a useful instrument to evaluate and improve quality of care. Copyright © 2011 SESPAS. Published by Elsevier Espana. All rights reserved.

  13. Kinematic Study of Ionized and Molecular Gases in Ultracompact HII Region in Monoceros R2

    Monoceros R2 (Mon R2) is an UltraCompact HII region (UCHII) surrounded by several PhotoDissociation Regions (PDRs). It is an excellent example to investigate the chemistry and physics of early stage of massive star formation due to its proximity (830pc) and brightness. Previous studies suggest that the wind from the star holds the ionized gas up against the dense molecular core and the higher pressure at the head drives the ionized gas along the shell. In order for the model to work, there should be evidence for dense molecular gas along the shell walls, irradiated by the UCHII region and perhaps entrained into the flow along the walls.We obtained the Immersion Grating INfrared Spectrograph (IGRINS) spectra of Mon R2 to study the kinematic patterns in the areas where ionized and molecular gases interact. The position-velocity maps from the high resolution (R~45,000) H- and K-band (1.4-2.5μm) IGRINS spectra demonstrate that the ionized gases (Brackett and Pfund series, He and Fe emission lines; Δv ≈ 40km/s) flow along the walls of the surrounding clouds. This is consistent with the model by Zhu et al. (2008). In the PV maps of the H2 emission lines there is no obvious motion (Δv ≈ 10km/s) of the molecular hydrogen right at the ionization boundary. This implies that the molecular gas is not taking part in the flow as the ionized gas is moving along the cavity walls.This work used the Immersion Grating Infrared Spectrograph (IGRINS) that was developed under a collaboration between the University of Texas at Austin and the Korea Astronomy and Space Science Institute (KASI) with the financial support of the US National Science Foundation (NSF; grant AST-1229522), of the University of Texas at Austin, and of the Korean GMTProject of KASI.

    Previous studies on the family of inter-metallic rare-earth compounds R 2 PdSi 3 revealed multifaceted magnetic properties, for instance, spin-glass like behavior. Experimental observations include: Signs of a crystallographic superstructure, complicated magnetic structures both in zero field and in applied magnetic fields as well as a generic phase in applied fields for compounds in the series with the heavy rare-earths R=Gd, Tb, Dy, Ho, Er and Tm. This thesis expands the studies on the magnetic properties of R 2 PdSi 3 employing mainly neutron scattering on single crystals with the focus on the compounds with R=Ho, Er and Tm. A detailed analysis of the crystallographic superstructure using modulation wave approach and group theory is presented. The resulting structure implies the existence of two different rare-earth sites with reduced symmetry and an arrangement of the different sites according to sequences as determined by the superstructure. It is shown that the reduced symmetry of the rare-earth sites is explicitly observed in the energy spectra of inelastic neutron scattering. The results on the magnetic structures and excitations are shown and discussed in the framework of the superstructure model. Specifically the generic phase in applied fields is interpreted as a direct consequence of the crystallographic superstructure. It is rather unusual that a crystallographic superstructure is playing such a decisive, and through the field dependence also tunable role in determining the magnetic properties as observed in R 2 PdSi 3 . The mediating interactions between the crystallographic part and the magnetic part of the system are discussed. (orig.)

    Full Text Available ABSTRACT This paper aimed to investigate the impact of levels of selectivity on the performance of equity funds using a methodology applied for the first time ever (as far as we know in the Brazilian market. As an indicator of the activity level of a fund, we proposed the coefficient of determination (R2 of the regression of its returns over market returns. In total, 867 funds were analyzed in the period between November 2004 and October 2014. The hypothesis tested is that more selective funds perform better to compensate for their higher operating costs. This hypothesis was confirmed in the Brazilian market. Dynamic equally-weighted portfolios of funds were simulated, according to their past R2 and alphas, with monthly rebalancing and 12-month moving windows. The portfolio of the most selective funds had a Sharpe ratio of 0.0494, on a monthly basis, while the portfolio of the least selective funds had a Sharpe ratio of -0.0314. Performance was also higher in evaluations involving excess returns, Jensen’s alpha, and accumulated returns, as well as when compared to randomly selected portfolios. Moreover, past performance (as measured by Jensen’s alpha was also a predictor of future performance. Particularly, the portfolio composed by funds with a higher past alpha and lower past R2 presented a Sharpe ratio of 0.1483 and a Jensen’s alpha of 0.87% (significant at 1%, while the one composed of funds with a lower past alpha and lower activity level presented a Sharpe ratio of -0.0673 and an alpha of -0.32% (also significant at 1%.

    Doctors' job satisfaction has been discussed internationally in recent years based on reports of increasing professional dissatisfaction. We have studied Norwegian doctors' job satisfaction and their general satisfaction with life. A survey was conducted among a representative sample of practicing Norwegian doctors in 2008. The validated 10-item Job Satisfaction Scale was used to assess job satisfaction. 1,072 (65 %) doctors responded. They reported a mean job satisfaction of 5.3 on a scale from 1 (very dissatisfied) to 7 (very satisfied). Job satisfaction increased with increasing age. Private practice specialists reported the highest level of job satisfaction (5.8), and general practitioners reported higher job satisfaction (5.5) than hospital doctors (5.1). Among specialty groups, community doctors scored highest (5.6) and doctors in surgical disciplines lowest (5.0). While long working hours was negatively correlated with job satisfaction, the perception of being professionally updated and having part-time affiliation(s) in addition to a regular job were positively correlated with job satisfaction. 52.9 % of doctors reported a very high general satisfaction. Norwegian doctors have a high level of job satisfaction. Satisfaction with life in general is also high and at least in line with that in the Norwegian population.

    LWR fuel testing is performed in the R2 reactor by irradiation in both loops and so-called boiling capsules. The loops have forced cooling, and the power can be measured calorimetrically by conventional instrumentation. The boiling capsules have convection cooling, and it has therefore been necessary to develop a special technique for power measurement, the delayed neutron detector (DND). The DND is a pneumatic rabbit system, which activates small uranium samples in the boiling capsules and counts the delayed neutrons for determination of the fission rate. This report describes the equipment used, the procedure of measurement, and the method of evaluation. (atuhor)

    Though the Baecklund transformation on time-like surfaces with constant mean curvature surfaces in R 2,1 has been obtained, it is not easy to obtain corresponding surfaces because the procedure of solving the related integrable system cannot be avoided when the Baecklund transformation is used. For sake of this, in this article, some special work is done to reform the Baecklund transformation to a recursion formula, by which we can construct time-like surfaces with constant mean curvature form known ones just by quadrature procedure.

    The local magnetic anisotropy of R ions in R2Fe14B (R = Dy, Ho) systems is studied based on a microscopic effective spin model constructed from the information obtained by using first-principles calculations. By taking into account up to 6-th order crystal electric field parameters, the model satisfactory describes the observed magnetization curves and the temperature dependence of anisotropy constants. We found that at low temperatures, the noncollinear structure appears in the Ho2Fe14B system reflecting the local magnetic anisotropy.

    The Rolling Deck to Repository (R2R) program is developing infrastructure to ensure the underway sensor data from NSF-supported oceanographic research vessels are routinely and consistently documented, preserved in long-term archives, and disseminated to the science community. We have published the entire R2R Catalog as a Linked Data collection, making it easily accessible to encourage linking and integration with data at other repositories. We are developing the R2R Linked Data collection with specific goals in mind: 1.) We facilitate data access and reuse by providing the richest possible collection of resources to describe vessels, cruises, instruments, and datasets from the U.S. academic fleet, including data quality assessment results and clean trackline navigation. We are leveraging or adopting existing community-standard concepts and vocabularies, particularly concepts from the Biological and Chemical Oceanography Data Management Office (BCO-DMO) ontology and terms from the pan-European SeaDataNet vocabularies, and continually re-publish resources as new concepts and terms are mapped. 2.) We facilitate data citation through the entire data lifecycle from field acquisition to shoreside archiving to (ultimately) global syntheses and journal articles. We are implementing globally unique and persistent identifiers at the collection, dataset, and granule levels, and encoding these citable identifiers directly into the Linked Data resources. 3.) We facilitate linking and integration with other repositories that publish Linked Data collections for the U.S. academic fleet, such as BCO-DMO and the Index to Marine and Lacustrine Geological Samples (IMLGS). We are initially mapping datasets at the resource level, and plan to eventually implement rule-based mapping at the concept level. We work collaboratively with partner repositories to develop best practices for URI patterns and consensus on shared vocabularies. The R2R Linked Data collection is implemented as a

    The Rolling Deck to Repository (R2R; http://rvdata.us/) program curates underway environmental sensor data from the U.S. academic oceanographic research fleet, ensuring data sets are routinely and consistently documented, preserved in long-term archives, and disseminated to the science community. Currently 25 in-service vessels contribute 7 terabytes of data to R2R each year, acquired from a full suite of geophysical, oceanographic, meteorological, and navigational sensors on over 400 cruises worldwide. To accommodate this large volume and variety of data, R2R has developed highly efficient stewardship procedures. These include scripted "break out" of cruise data packages from each vessel based on standard filename and directory patterns; automated harvest of cruise metadata from the UNOLS Office via Web Services and from OpenXML-based forms submitted by vessel operators; scripted quality assessment routines that calculate statistical summaries and standard ratings for selected data types; adoption of community-standard controlled vocabularies for vessel codes, instrument types, etc, provided by the NERC Vocabulary Server, in lieu of maintaining custom local term lists; and a standard package structure based on the IETF BagIt format for delivering data to long-term archives. Documentation and standard post-field products, including quality-controlled shiptrack navigation data for every cruise, are published in multiple services and formats to satisfy a diverse range of clients. These include Catalog Service for Web (CSW), GeoRSS, and OAI-PMH discovery services via a GeoNetwork portal; OGC Web Map and Feature Services for GIS clients; a citable Digital Object Identifier (DOI) for each dataset; ISO 19115-2 standard geospatial metadata records suitable for submission to long-term archives as well as the POGO global catalog; and Linked Open Data resources with a SPARQL query endpoint for Semantic Web clients.

    Full Text Available Male height is associated with high mate value. In particular, tall men are perceived as more attractive, dominant and of a higher status than shorter rivals, resulting in a greater lifetime reproductive success. Female infidelity and relationship dissolution may therefore present a greater risk to short men. It was predicted that tall men would report greater relationship satisfaction and lower jealousy and mate retention behavior than short men. Ninety eight heterosexual men in a current romantic relationship completed a questionnaire. Both linear and quadratic relationships were found between male height and relationship satisfaction, cognitive and behavioral jealousy. Tall men reported greater relationship satisfaction and lower levels of cognitive or behavioral jealousy than short men. In addition, linear and quadratic relationships were found between male height and a number of mate retention behaviors. Tall and short men engaged in different mate retention behaviors. These findings are consistent with previous research conducted in this area detailing the greater attractiveness of tall men.

    Job satisfaction is an important factor in health care settings. Strong empirical evidence supports a causal relationship between job satisfaction, patient safety and quality of care. However, there have not been any studies exploring the job satisfaction of Malaysian nurses. The main purpose of this qualitative descriptive study was to explore the factors related to feelings of job satisfaction as well as job dissatisfaction experienced by registered nurses in Malaysia. A convenient sample of 46 Malaysian nurses recruited from a large hospital (number of beds = 895) participated in the study. A total of seven focus group discussions were conducted with nurses from surgical, medical and critical care wards. A semi-structured interview guide was used to facilitate the interviews, which were audio-recorded, transcribed verbatim and checked. The transcripts were used as data and were analysed using a thematic approach. The study identified three main themes that influenced job satisfaction: (1) nurses' personal values and beliefs; (2) work environment factors and (3) motivation factors. Concerning the nurses' personal values and beliefs, the ability to help people made the nurses felt honoured and happy, which indirectly contributed to job satisfaction. For work environment factors, team cohesion, benefit and reward, working conditions play an important role in the nurses' job satisfaction. Motivation factors, namely, professional development and clinical autonomy contributed to job satisfaction. It is important for nurse leaders to provide more rewards, comfortable work environments and to understand issues that affect nurses' job satisfaction. Our findings highlight the importance of factors that can improve nurses' job satisfaction. The study provides basic information for hospital administrators in planning effective and efficient policies to improve nursing job satisfaction in order to increase the quality of patient care and decrease nursing turnover. © 2014

    There remains a lack of investigation into which factors patients and families value the most in their experience at pediatric dermatology clinics. Most of the current literature on quality improvement in dermatology does not encompass the pediatric population. To determine the drivers that are most predictive of a positive patient experience, we observed the indirect relationship between several factors of the patient experience and their role in patient satisfaction. Patient satisfaction surveys were distributed after their visits to patients at four pediatric dermatology clinics in one children's academic health system. Data were collected and organized into the top 30 survey variables with which patients expressed satisfaction on a 5-point Likert scale. Pearson product-moment correlation coefficients (r) for each variable with regard to "likelihood of your recommending our practice to others" were calculated. A total of 516 families completed patient satisfaction surveys. Analyses of top box scores showed that the strongest predictors of patient satisfaction were the likelihood of recommending care provider (r = .77, P = dermatology. Identifying such variables that shape patients' assessments of their experience can guide future quality improvement plans in the specialty. © 2017 Wiley Periodicals, Inc.

The needbased motivational theories relate need and psychological gratification to motivation and jobsatisfaction; they consider performance as the endresult. However, Lawler and Porter postulatereversely that job performance leads to job satisfaction. The study focuses on testing the degree anddirection of the relationship between Performance and Job Satisfaction with intervening variablessuch as job relations, commitment, role conflict, value system, motivation and organizational climateand with socio-economic variables. The study is conducted on 928 employees drawn from 13 publicsector and 5 private sector organizations using simple random sampling and males as the matchingsample in the State of Andhra Pradesh, India. It isevident from the study that the performance levelof the employees is significantly lesser than theirjob satisfaction level. The analysis leads to state thatall those performing well are satisfied and all those satisfied do not perform well indicating thatperformance leads to job satisfaction, job satisfaction does not lead necessarily to performance andthe relationship is intertwined. This empirical evidence supports the theory of Lawler and Porter andsets direction for future studies at micro level.

    Using a sample of 310 married respondents from one U.S. Midwestern state, a test was conducted to examine the association of financial satisfaction and financial stressors in a spouse's decision to stay married to the same person or leave the relationship. The role of demographic and socioeconomic variables, religiosity, psychological constructs, financial satisfaction, and financial stressors as factors influencing marital satisfaction was tested. Financial stressors were measured using a list of financial stressors adapted from the literature. Financial satisfaction was measured with a one-item scale. The Kansas Marital Satisfaction Scale was used as a validation tool to assess whether individuals would marry or not marry again. Religiosity and financial satisfaction were positively associated with marital satisfaction. A negative interaction between financial satisfaction and financial stressors was also noted. Findings suggest that respondents who are financially satisfied tend to be more stable in their marriages.

    From the analysis for various mobile robots competed in DARPA Robotics Challenge, there are some drawbacks in using two or four legs because bipedal locomotion is not yet suitable for maintaining stability and quadrupedal locomotion is difficult to go through narrow aisles. Motivated by the above observations, we propose a K-R2D2 robot platform with three legs arranged in the form of a triangle like as R2-D2 robot which is a fictional robot character in the Star Wars movies. This robot has 3 legs with tracks in each sole of the leg. It is statically stable since there are three contact points to ground. In addition, three legs are also possible to design a structure walking stairs that can expand and contract in the vertical direction. This paper has presented the conceptual design, it is developed on the purpose of quick response instead of emergent workers to the extreme conditions disasters. This robot is emergency response robot platform KR2D2 with three legs, which is statically stable to walk or wheel depending on the terrains and move quickly as possible as on uneven terrain or stairs.

    Shadow corrosion is a phenomenon which occurs when zirconium alloys are in contact with or in proximity to other metallic objects in a boiling water reactor environment (BWR, RBMK, SGHWR etc.). An enhanced corrosion occurs on the zirconium alloy with the appearance of a 'shadow' of the metallic object. The magnitude of the shadow corrosion can be significant, and is potentially limiting for the lifetime of certain zirconium alloy components in BWRs and other reactors with a similar water chemistry. In order to evaluate the suitability of the In-Core Autoclave (INCA) in the Studsvik R2 materials testing reactor as an experimental facility for studying shadow corrosion, a demonstration test has been performed. A number of test specimens consisting of Zircaloy-2 tubing in contact with Inconel were exposed in an oxidising water chemistry. Some of the specimens were placed within the reactor core and some above the core. The conclusion of this experiment after post irradiation examination is that it is possible to use the INCA facility in the Studsvik R2 reactor to develop a significant level of shadow corrosion after only 800 hours of irradiation.

  17. Minimal $R+R^2$ Supergravity Models of Inflation Coupled to Matter

    Ferrara, S

    2014-01-01

    The supersymmetric extension of "Starobinsky" $R+\\alpha R^2$ models of inflation is particularly simple in the "new minimal" formalism of supergravity, where the inflaton has no scalar superpartners. This paper is devoted to matter couplings in such supergravity models. We show how in the new minimal formalism matter coupling presents certain features absent in other formalisms. In particular, for the large class of matter couplings considered in this paper, matter must possess an R-symmetry, which is gauged by the vector field which becomes dynamical in the "new minimal" completion of the $R+\\alpha R^2$ theory. Thus, in the dual formulation of the theory, where the gauge vector is part of a massive vector multiplet, the inflaton is the superpartner of the massive vector of a nonlinearly realized R-symmetry. The F-term potential of this theory is of no-scale type, while the inflaton potential is given by the D-term of the gauged R-symmetry. The absolute minimum of the potential is always exactly supersymmetri...

    The sweet taste receptors T1r2 and T1r3 are included in the T1r taste receptor family that belongs to class C of the G protein-coupled receptors. Heterodimerization of T1r2 and T1r3 is required for the perception of sweet substances, but little is known about the mechanisms underlying this heterodimerization, including membrane trafficking. We developed tagged mouse T1r2 and T1r3, and human T1R2 and T1R3 and evaluated membrane trafficking in human embryonic kidney 293 (HEK293) cells. We found that human T1R3 surface expression was only observed when human T1R3 was coexpressed with human T1R2, whereas mouse T1r3 was expressed without mouse T1r2 expression. A domain-swapped chimera and truncated human T1R3 mutant showed that the Venus flytrap module and cysteine-rich domain (CRD) of human T1R3 contain a region related to the inhibition of human T1R3 membrane trafficking and coordinated regulation of human T1R3 membrane trafficking. We also found that the Venus flytrap module of both human T1R2 and T1R3 are needed for membrane trafficking, suggesting that the coexpression of human T1R2 and T1R3 is required for this event. These results suggest that the Venus flytrap module and CRD receive taste substances and play roles in membrane trafficking of human T1R2 and T1R3. These features are different from those of mouse receptors, indicating that human T1R2 and T1R3 are likely to have a novel membrane trafficking system.

    We report on the high-pressure syntheses and detailed characterizations of two effective pseudospin S =1 /2 XY pyrochlores E r2P t2O7 and Y b2P t2O7 via x-ray/neutron powder diffraction, dc and ac magnetic susceptibility, and specific-heat measurements down to 70 mK. We found that both compounds undergo long-range magnetic transitions at TN ,C≈0.3 K , which are ascribed to an antiferromagnetic- and ferromagnetic-type order for E r2P t2O7 and Y b2P t2O7 , respectively, based on the field dependence of their transition temperatures as well as the systematic comparisons with other similar pyrochlores R2B2O7 (R =Er ,Yb ;B =Sn ,Ti ,Ge ). The observed TN of E r2P t2O7 is much lower than that expected from the relationship of TN versus the ionic radius of B4 + derived from the series of E r2B2O7 , while the TC of Y b2P t2O7 is the highest among the series of ferromagnetic compounds Y b2B2O7 (B =Sn ,Pt ,Ti ). Given the monotonic variation of the lattice constant as a function of the B -cation size across these two series of R2B2O7 (R =Er ,Yb ), the observed anomalous values of TN ,C in the Pt-based XY pyrochlores imply that another important factor beyond the nearest-neighbor R -R distance is playing a role. In light of the anisotropic exchange interactions Jex={Jz z,J±,J±±,Jz ± } for the S =1 /2 XY pyrochlores, we have rationalized these observations by considering a weakened (enhanced) antiferromagnetic planar J± (ferromagnetic Ising-like Jz z) due to strong Pt 5 d -O 2 p hybridization within the plane perpendicular to the local [111] direction.

    The literature documents that job satisfaction is positively correlated with worker performance and pro- ductivity. We examine whether aggregate job satisfaction in a certain labor market environment can have an impact on individual-level job satisfaction. If the answer is yes, then policies targeted to increase job satisfaction can increase productivity not only directly, but through spillover externalities too. We seek an answer to this question using two different data sets from the United...

    With informatics providing an increasingly important set of tools for geoscientists, it is critical to train the next generation of scientists in information and data techniques. The NSF-supported Rolling Deck to Repository (R2R) Program works with the academic fleet community to routinely document, assess, and preserve the underway sensor data from U.S. research vessels. The Ocean Data Interoperability Platform (ODIP) is an EU-US-Australian collaboration fostering interoperability among regional e-infrastructures through workshops and joint prototype development. The need to align terminology between systems is a common challenge across all of the ODIP prototypes. Five R2R students were supported to address aspects of semantic interoperability within ODIP. Developing a vocabulary matching service that links terms from different vocabularies with similar concept. The service implements Google Refine reconciliation service interface such that users can leverage Google Refine application as a friendly user interface while linking different vocabulary terms. Developing Resource Description Framework (RDF) resources that map Shipboard Automated Meteorological Oceanographic System (SAMOS) vocabularies to internationally served vocabularies. Each SAMOS vocabulary term (data parameter and quality control flag) will be described as an RDF resource page. These RDF resources allow for enhanced discoverability and retrieval of SAMOS data by enabling data searches based on parameter. Improving data retrieval and interoperability by exposing data and mapped vocabularies using Semantic Web technologies. We have collaborated with ODIP participating organizations in order to build a generalized data model that will be used to populate a SPARQL endpoint in order to provide expressive querying over our data files. Mapping local and regional vocabularies used by R2R to those used by ODIP partners. This work is described more fully in a companion poster. Making published Linked Data

    In a changing and flexible labour market it is important to clarify the role of environmental and personal variables that contribute to obtaining adequate levels of job satisfaction. The aim of the present study is to analyze the direct effects of employability and personal initiative on intrinsic, extrinsic and social job satisfaction, clarifying their cumulative and interactive effects. The study has been carried out in a sample of 1319 young Spanish workers. Hypotheses were tested by means of the moderated hierarchical regression analysis. Results show that employability and personal initiative predict in a cumulative way the intrinsic, extrinsic and social job satisfaction. Moreover, the interaction between employability and personal initiative increases the prediction of these two variables on intrinsic and extrinsic job satisfaction. Results also indicate that higher values of employability when initiative is also high are associated to higher levels of intrinsic and extrinsic satisfaction. These results have implications for theory and practice in a context of new employment relations.

    2005-08-01

    To determine the financial impact of poor customer satisfaction and the value of information gained from using a 1-question customer-satisfaction survey in a medical setting. A single-question customer-satisfaction survey was collected from customers presenting to an academic otolaryngology head and neck surgery outpatient clinic. The overall response rate was 25%, overall net promoter score was 67.3%, lowest net promoter score occurred on Wednesday and Friday, overall net potential referrals were 872, and potential lost revenue from dissatisfied customers equaled US 2.3 million dollars. A single-question customer-satisfaction survey may help identify areas of customer dissatisfaction that lead to a significant source of lost revenue. The competitive forces in today's health care environment require medical practices to address issues related to customer satisfaction.

    We examined the association between older adults' mealtime interactions at senior centers in Shanghai and their life satisfaction. Competing hypotheses, derived from socioemotional selectivity theory and activity theory, were tested. Data were obtained from the 2011 Shanghai senior center service utilization survey ( N = 320). Relationships between respondents' mealtime interactions and life satisfaction were tested using multilevel regression modeling. After adjusting for demographics, interactions with tablemates (companionship, self-disclosure, and instrumental support) were positively associated with respondents' life satisfaction. These associations varied by senior centers. However, the number of tablemates was not significantly associated with respondents' life satisfaction. Findings support the activity-theory-based hypothesis that mealtime interactions are related to older adults' life satisfaction independent of the number of tablemates. This study illuminates the value of social interactions in the context of community dining programs for the rapidly increasing older population in urban China.

    Full Text Available The purpose of this study was to verify a model of user’s satisfaction of an e-learning environment based upon platform using behaviors. This is a non-experimental study. The data was collected from system management logs and users satisfaction survey after learning service. Total 314 users were invited in this study. First, theory model was identified. Second, the satisfaction survey results were prepared. Third, the behavior data of each survey subject were prepared. A CFA procedure were conducted to verify whether the data fits into the model. The model fit is positive with χ2 = 2.06, p-value=.151, df= 1, RMSEA=.058. The proposed two-factor theory model with simple structure fit the data. The love e-learning and satisfaction of e-learning factors are significantly supporting the hypothesis of a relationship between the factors. The findings suggested that identifying satisfaction from behavior is possible.

  11. Detection of maltodextrin and its discrimination from sucrose are independent of the T1R2 + T1R3 heterodimer.

    Smith, Kimberly R; Spector, Alan C

    2017-10-01

    Maltodextrins, such as Maltrin and Polycose, are glucose polymer mixtures of varying chain lengths that are palatable to rodents. Although glucose and other sugars activate the T1R2 + T1R3 "sweet" taste receptor, recent evidence from T1R2- or T1R3-knockout (KO) mice suggests that maltodextrins, despite their glucose polymer composition, activate a separate receptor mechanism to generate a taste percept qualitatively distinguishable from that of sweeteners. However, explicit discrimination of maltodextrins from prototypical sweeteners has not yet been psychophysically tested in any murine model. Therefore, mice lacking T1R2 + T1R3 and wild-type controls were tested in a two-response taste discrimination task to determine whether maltodextrins are 1 ) detectable when both receptor subunits are absent and 2 ) perceptually distinct from that of sucrose irrespective of viscosity, intensity, and hedonics. Most KO mice displayed similar Polycose sensitivity as controls. However, some KO mice were only sensitive to the higher Polycose concentrations, implicating potential allelic variation in the putative polysaccharide receptor or downstream pathways unmasked by the absence of T1R2 + T1R3. Varied Maltrin and sucrose concentrations of approximately matched viscosities were then presented to render the oral somatosensory features, intensity, and hedonic value of the solutions irrelevant. Although both genotypes competently discriminated Maltrin from sucrose, performance was apparently driven by the different orosensory percepts of the two stimuli in control mice and the presence of a Maltrin but not sucrose orosensory cue in KO mice. These data support the proposed presence of an orosensory receptor mechanism that gives rise to a qualitatively distinguishable sensation from that of sucrose.

    2007-12-01

    Customer satisfaction is defined as a measure of how a firm's product or service performs compared to customer's expectations. It has long been a subject of research due to its importance for measuring marketing and business performance. A lot of models have been developed for its measurement. This paper propose a simulation model using employee satisfaction as one of the most important factors leading to customer satisfaction (the others being expectations and disconfirmation of expectations). Data obtained from a two-year survey in customers of banks in Greece were used. The application of three approaches regarding employee satisfaction resulted in greater customer satisfaction when there is serious effort to keep employees satisfied.

    Adam, S.; Adam, G.; Burzo, E.

    1985-12-01

    Crystal-field effects are expected to be important in R 2 Fe 14 B compounds. Within a model-independent approach, it is proved that four distinct rare-earth sites exist with respect to the crystalline electric fields, namely, R(4f; z=0), R(4f; z=0.5 c), R(4g; z=0), and R(4g; z=0.5 c), and relationships are established between the corresponding crystal-fields coefficients. Further, generalized Stevens parametrizations of the crystal field coefficients are derived at three levels of approximation for the interatomic forces inside the crystal. A crystal lattice dressing effect upon the radial electronic integrals is found to occur, the magnitude of which depends on the deviation of the interatomic forces from Coulombian. Finally, computation of crystal-field coefficients in Nd 2 Fe 14 B leads to results which raise questions about the validity of the simple Coulomb point-charge model. (author)

  18. Problems with change in R2 as applied to theory of reasoned action research.

    Science.gov (United States)

    Trafimow, David

    2004-12-01

    The paradigm of choice for theory of reasoned action research seems to depend largely on the notion of change in variance accounted for (DeltaR2) as new independent variables are added to a multiple regression equation. If adding a particular independent variable of interest increases the variance in the dependent variable that can be accounted for by the list of independent variables, then the research is deemed to be 'successful', and the researcher is considered to have made a convincing argument about the importance of the new variable. In contrast to this trend, I present arguments that suggest serious problems with the paradigm, and conclude that studies on attitude-behaviour relations would advance the field of psychology to a far greater extent if researchers abandoned it.

    1991-01-01

    Irradiation of 7 LEU fuel elements is underway in the Studsvik R2 reactor. Four of these have 490 g U-235, and three 320 g U-235 loading, and the enrichment is 19.7% for all of them. The irradiation of LEU fuel started in 1987. The heavier elements have burnup figures 67% (CERCA), 50% (B and W), 47% (NUKEM) and 19% (B and W). One of the lighter elements has reached a burnup of 65%. To support the whole-core conversion process, reactor physical calculations were performed to see if a one-step conversion is possible with a suitable fuel management strategy such that all HEU fuel is burned up. The calculations show that it is possible to perform such a conversion with fuel elements containing 400 g U-235. (orig.)

    Up to the present time, Mitsubishi has manufactured approximately 3000 fuel assemblies for Japanese PWRs, of which performance in reactors is satisfactory under base load operation. For the forthcoming load following age in Japan, expected in mid eighties, Mitsubishi is performing various R and D programs, so that load following operation can be smoothly introduced with current good performance maintained. R and D programs consist of two phases. One is the verification and demonstration of power ramping and cycling capability of the current design fuels, and the other is the development of remedy fuels with more operational margin. This paper describes the recent results obtained for the former phase, especially for the following two programs: (1) Power cycling and ramp test in R-2; (2) Power ramp demonstration (PRD) in Mihama Unit 2 (PRD-1). PIE works for power cycling and ramp test rods have been almost completed. The second PRD will be performed early in 1983

    ESR of incorporated Cu 2+ was used in the detection of micro-inhomogeneity in xR 2 O x yMgO x (100-x-y)B 2 O 3 glasses. The inhomogeneous region determined by ESR was found to be far wider than that obtained by opalescence. It was concluded that in the glasses of x + y approx. 2+ tends to accelerate the simultaneous formation of boroxol and diborate groups and in the glasses of x + y approx. < 15, boroxol group and pyroborate ion. The conclusion was confirmed by laser Raman scattering. Molecular volume was measured over the whole glass-forming region to explore the correlation between the micro-structure and a macroscopic property of the glasses. It showed no marked change at the specified composition where micro-structure changed. (orig.)

    2018-04-01

    A Python package, pyres, was written to handle common as well as specialized input and output tasks for the R2 electrical resistivity (ER) modeling program. Input steps including handling field data, creating quadrilateral or triangular meshes, and data filtering allow repeatable and flexible ER modeling within a programming environment. pyres includes non-trivial routines and functions for locating and constraining specific known or separately-parameterized regions in both quadrilateral and triangular meshes. Three basic examples of how to run forward and inverse models with pyres are provided. The importance of testing mesh convergence and model sensitivity are also addressed with higher-level examples that show how pyres can facilitate future research-grade ER analyses.

  3. The essential role of AMPA receptor GluR2 subunit RNA editing in the normal and diseased brain

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available AMPA receptors are comprised of different combinations of GluR1-GluR4 (also known as GluA1-GluA4 and GluR-A to GluR-D subunits. The GluR2 subunit is subject to Q/R site RNA editing by the ADAR2 enzyme, which converts a codon for glutamine (Q, present in the GluR2 gene, to a codon for arginine (R found in the mRNA. AMPA receptors are calcium (Ca2+-permeable if they contain the unedited GluR2(Q subunit or if they lack the GluR2 subunit. While most AMPA receptors in the brain contain the edited GluR2(R subunit and are therefore Ca2+-impermeable, recent evidence suggests that Ca2+-permeable GluR2-lacking AMPA receptors are important in synaptic plasticity and learning. However, the presence of Ca2+-permeable AMPA receptors containing unedited GluR2 leads to excitotoxic cell loss. Recent studies have indicated that RNA editing of GluR2 is deregulated in diseases, such as amyotrophic lateral sclerosis (ALS, as well in acute neurodegenerative conditions, such as ischemia. More recently, studies have investigated the regulation of RNA editing and possible causes for its deregulation during disease. In this review, we will explore the role of GluR2 RNA editing in the healthy and diseased brain and outline new insights into the mechanisms that control this process.

More than 600 biological samples of archaea, bacteria (as biofilms and in planktonic form, lichens, fungi, plant seeds, triops eggs, mosses and 150 samples of organic compounds were exposed to the harsh space environment and to parameters similar to those on the Mars surface. Radiation dosimeters distributed over the whole facility complemented the scientific payload. Three extravehicular activities later the chemical samples were returned to Earth on March 2, 2016, with Soyuz 44S, having spent 588 days in space. The biological samples arrived back later, on June 18, 2016, with 45S, after a total duration in space of 531 days. The exposure of the samples to Low Earth Orbit vacuum lasted for 531 days and was divided in two parts: protected against solar irradiation during the first 62 days, followed by exposure to solar radiation during the subsequent 469 days. In parallel to the space mission, a Mission Ground Reference (MGR experiment with a flight identical Hardware and a complete flight identical set of samples was performed at the premises of DLR (German Aerospace Center in Cologne by MUSC (Microgravity User Support Center, according to the mission data either downloaded from the ISS (temperature data, facility status, inner pressure status or provided by RedShift Design and Engineering BVBA, Belgium (calculated ultra violet radiation fluence data.

    As one of the adverse effects of oxaliplatin, a key agent in colon cancer chemotherapy, a taste disorder is a severe issue in a clinical situation because it decreases the quality of life of patients. However, there is little information on the mechanism underlying the oxaliplatin-induced taste disorder. Here, we examined the molecular and behavioral characteristics of the oxaliplatin-induced taste disorder in rats. Oxaliplatin (4-16 mg/kg) was administered to Sprague-Dawley (SD) rats intraperitoneally for 2 d. Expression levels of mRNA and protein of taste receptors in circumvallate papillae (CP) were measured by real-time quantitative polymerase chain reaction (PCR) and immunohistochemistry, respectively. Taste sensitivity was assessed by their behavioral change using a brief-access test. Morphological change of the taste buds in CP was evaluated by hematoxyline-eosin (HE) staining, and the number of taste cells in taste buds was counted by immunohistochemical analysis. Among taste receptors, the expression levels of mRNA and protein of T1R2, a sweet taste receptor subunit, were increased transiently in CP of oxaliplatin-administered rats on day 7. In a brief-access test, the lick ratio was decreased in oxaliplatin-administered rats on day 7 and the alteration was recovered to the control level on day 14. There was no detectable alteration in the morphology of taste buds, number of taste cells or plasma zinc level in oxaliplatin-administered rats. These results suggest that decreased sensitivity to sweet taste in oxaliplatin-administered rats is due, at least in part, to increased expression of T1R2, while these alterations are reversible.

    This study estimated the relative influence of age/generation and tenure on job satisfaction and workplace climate perceptions. Data from the 2004, 2008, and 2012 Veterans Health Administration All Employee Survey (sample sizes >100 000) were examined in general linear models, with demographic characteristics simultaneously included as independent variables. Ten dependent variables represented a broad range of employee attitudes. Age/generation and tenure effects were compared through partial η(2) (95% confidence interval), P value of F statistic, and overall model R(2). Demographic variables taken together were only weakly related to employee attitudes, accounting for less than 10% of the variance. Consistently across survey years, for all dependent variables, age and age-squared had very weak to no effects, whereas tenure and tenure-squared had meaningfully greater partial η(2) values. Except for 1 independent variable in 1 year, none of the partial η(2) confidence intervals for age and age-squared overlapped those of tenure and tenure-squared. Much has been made in the popular and professional press of the importance of generational differences in workplace attitudes. Empirical studies have been contradictory and therefore inconclusive. The findings reported here suggest that age/generational differences might not influence employee perceptions to the extent that human resource and management practitioners have been led to believe.

    This study explores the characteristics of professional nursing work environments that may affect nursing turnover and satisfaction within a large Ecuadorian hospital. Nursing turnover is a challenge and may compromise patient care. Work dissatisfaction contributes to high turnover. Improving nurse satisfaction can contribute to better patient outcomes. Eighty-eight nurses participated in a quantitative and qualitative survey focusing on nursing satisfaction, turnover and selected organisation characteristics. Issues that may affect nurse satisfaction and turnover were identified using questions from the Nursing Work Index: pay, insufficient number of nurses, undervaluing of nurses by public and the medical team, limited advancement opportunities, lack of autonomy and inflexibility in schedule. Other themes identified from qualitative data are reported. The top factor of decreased satisfaction was low pay as indicated by the Nursing Work Index. The qualitative results showed that low pay was the factor for nurse turnover. Additional factors related to nursing satisfaction can be addressed to improve nurse retention. Along with increasing nursing pay, strategies to consider in decreasing turnover and increasing satisfaction included: providing opportunities for nursing advancement, promoting the value of nursing, creating clinical protocols and enhancing autonomy. This study adds to knowledge about nursing needs and satisfaction in South America. © 2013 John Wiley & Sons Ltd.

    2016-03-01

    This study aims to undertake a concept analysis of job satisfaction in the nursing profession. Around current global shortage of nurses, it is important to stabilize the nursing workforce. Nurses' job satisfaction has been found to be related to intention to leave. In the nursing profession, there is a lack of evidence to support the attributes of nurses' job satisfaction. Walker and Avant's approach of concept analysis was used. The main attributes of job satisfaction from this study are (1) fulfillment of desired needs within the work settings, (2) happiness or gratifying emotional responses towards working conditions, and (3) job value or equity. These attributes are influenced by antecedent conditions like demographic, emotional, work characteristics and environmental variables. Additionally, the consequences of nurses' job satisfaction have a significant impact on both nurses and patients. This study integrated both the content and process of motivational theories to generate the attributes of job satisfaction in nursing that overcome the limitation of the previous studies, which looked only at the definitions of nurses' job satisfaction based on content motivational theories. The findings of this study can facilitate both nursing researchers to develop a cultural adaption instrument and policy makers to improve clinical nursing practice. This analysis provides nurse managers with a new perspective to deal with nurses' job satisfaction by taking into account all the attributes that influence it in the nursing field. © 2015 International Council of Nurses.

    To evaluate the automated two-point Dixon screening sequence for the detection and estimated quantification of hepatic iron and fat compared with standard sequences as a reference. One hundred and two patients with suspected diffuse liver disease were included in this prospective study. The following MRI protocol was used: 3D-T1-weighted opposed- and in-phase gradient echo with two-point Dixon reconstruction and dual-ratio signal discrimination algorithm (''screening'' sequence); fat-saturated, multi-gradient-echo sequence with 12 echoes; gradient-echo T1 FLASH opposed- and in-phase. Bland-Altman plots were generated and correlation coefficients were calculated to compare the sequences. The screening sequence diagnosed fat in 33, iron in 35 and a combination of both in 4 patients. Correlation between R2* values of the screening sequence and the standard relaxometry was excellent (r = 0.988). A slightly lower correlation (r = 0.978) was found between the fat fraction of the screening sequence and the standard sequence. Bland-Altman revealed systematically lower R2* values obtained from the screening sequence and higher fat fraction values obtained with the standard sequence with a rather high variability in agreement. The screening sequence is a promising method with fast diagnosis of the predominant liver disease. It is capable of estimating the amount of hepatic fat and iron comparable to standard methods.

    To evaluate the automated two-point Dixon screening sequence for the detection and estimated quantification of hepatic iron and fat compared with standard sequences as a reference. One hundred and two patients with suspected diffuse liver disease were included in this prospective study. The following MRI protocol was used: 3D-T1-weighted opposed- and in-phase gradient echo with two-point Dixon reconstruction and dual-ratio signal discrimination algorithm (''screening'' sequence); fat-saturated, multi-gradient-echo sequence with 12 echoes; gradient-echo T1 FLASH opposed- and in-phase. Bland-Altman plots were generated and correlation coefficients were calculated to compare the sequences. The screening sequence diagnosed fat in 33, iron in 35 and a combination of both in 4 patients. Correlation between R2* values of the screening sequence and the standard relaxometry was excellent (r = 0.988). A slightly lower correlation (r = 0.978) was found between the fat fraction of the screening sequence and the standard sequence. Bland-Altman revealed systematically lower R2* values obtained from the screening sequence and higher fat fraction values obtained with the standard sequence with a rather high variability in agreement. The screening sequence is a promising method with fast diagnosis of the predominant liver disease. It is capable of estimating the amount of hepatic fat and iron comparable to standard methods.

    This study explores whether different religions experience different levels of happiness and life satisfaction and in case this is affected by country economic and cultural environment. Using World Value Survey (from 1981 to 2014), this study found that individual religiosity and country level of development play a significant role in shaping people's subjective well-being (SWB). Protestants, Buddhists and Roman Catholic were happier and most satisfied with their lives compared to other religious groups. Orthodox has the lowest SWB. Health status, household's financial satisfaction and freedom of choice are means by which religious groups and governments across the globe can improve the SWB of their citizens.

    Full Text Available The present study investigated the role of emotional intelligence and emotional schema in marital satisfaction among women. A sample of 200 married women (100 employed and 100 household women was selected randomly and completed measures of emotional schemas, emotional intelligence, and marital satisfaction. The results of stepwise regression analysis showed that attention and clarity components of emotional intelligence are significant predictors of most marital satisfaction dimensions. Also, blame, agreement, simplistic view of emotions and higher values towards emotional schemas predicted different dimensions of marital satisfaction. Based on the findings it can be concluded that the emotional intelligence and effective emotional schema play a key role in marital satisfaction.

    To evaluate the accuracy and sensitivity of quantitative susceptibility mapping (QSM) and transverse relaxation rate (R2*) mapping in the measurement of brain iron deposition. Super paramagnetic iron oxide (SPIO) phantoms and mouse models of Parkinson's disease (PD) related to iron deposition in the substantia nigra (SN) underwent 7.0 T magnetic resonance (MR) scans (Bruker, 70/16) with a multi-echo 3D gradient echo sequence, and the acquired data were processed to obtain QSM and R2*. Linear regression analysis was performed for susceptibility and R2* in the SPIO phantoms containing 5 SPIO concentrations (30, 15, 7.5, 3.75 and 1.875 µg/mL) to evaluate the accuracy of QSM and R2* in quantitative iron analysis. The sensitivities of QSM and R2* mapping in quantitative detection of brain iron deposition were assessed using mouse models of PD induced by 1-methyl-4-phenyl-1,2,3,6-tetrahy-dropyridine (MPTP) in comparison with the control mice. In SPIO phantoms, QSM provided a higher accuracy than R2* mapping and their goodness-of-fit coefficients (R 2 ) were 0.98 and 0.89, respectively. In the mouse models of PD and control mice, the susceptibility of the SN was significantly higher in the PD models (5.19∓1.58 vs 2.98∓0.88, n=5; Pbrain iron deposition than R2*, and the susceptibility derived by QSM can be a potentially useful biomarker for studying PD.

    In patients with stable international normalized ratios, 12-week extended-interval warfarin monitoring can be considered; however, predictors of success with this strategy are unknown. The previously validated SAMe-TT 2 R 2 score (considering sex, age, medical history, treatment, tobacco, and race) predicts anticoagulation control during standard follow-up (every 4 weeks), with lower scores associated with greater time in therapeutic range. To evaluate the ability of the SAMe-TT 2 R 2 score in predicting success with extended-interval warfarin follow-up in patients with previously stable warfarin doses. In this post hoc analysis of a single-arm feasibility study, baseline SAMe-TT 2 R 2 scores were calculated for patients with ≥1 extended-interval follow-up visit. The primary analysis assessed achieved weeks of extended-interval follow-up according to baseline SAMe-TT 2 R 2 scores. A total of 47 patients receiving chronic anticoagulation completed a median of 36 weeks of extended-interval follow-up. The median baseline SAMe-TT 2 R 2 score was 1 (range 0-5). Lower SAMe-TT 2 R 2 scores appeared to be associated with greater duration of extended-interval follow-up achieved, though the differences between scores were not statistically significant. No individual variable of the SAMe-TT 2 R 2 score was associated with achieved weeks of extended-interval follow-up. Analysis of additional patient factors found that longer duration (≥24 weeks) of prior stable treatment was significantly associated with greater weeks of extended-interval follow-up completed ( P = 0.04). Conclusion and Relevance: This pilot study provides limited evidence that the SAMe-TT 2 R 2 score predicts success with extended-interval warfarin follow-up but requires confirmation in a larger study. Further research is also necessary to establish additional predictors of successful extended-interval warfarin follow-up.

  19. Distance Constraint Satisfaction Problems

    We study the complexity of constraint satisfaction problems for templates Γ that are first-order definable in ({ Z}; {suc}), the integers with the successor relation. Assuming a widely believed conjecture from finite domain constraint satisfaction (we require the tractability conjecture by Bulatov, Jeavons and Krokhin in the special case of transitive finite templates), we provide a full classification for the case that Γ is locally finite (i.e., the Gaifman graph of Γ has finite degree). We show that one of the following is true: The structure Γ is homomorphically equivalent to a structure with a certain majority polymorphism (which we call modular median) and CSP(Γ) can be solved in polynomial time, or Γ is homomorphically equivalent to a finite transitive structure, or CSP(Γ) is NP-complete.

    Full Text Available The loyalty programs are often part of a comprehensive strategy for customer relationship and provide a good way to identify and maintain customers with greater value than others. The main objective of this paper is to show the role of loyalty programs affecting customer satisfaction in retail. The purpose of the empirical research was to discover the effects of loyalty programs on customer satisfaction. Research has shown (N= 53 that the loyalty program is not the determinating factor. All other examined factors such as product range, price, locationof the store and customers relationship proved to be the more relevant for consumer satisfaction.
