    Full Text Available BACKGROUND: The occurrence of Parkinson's disease (PD is known to be associated both with increased nigrostriatal iron content and with low serum cholesterol and PD, but there has been no study to determine a potential relationship between these two factors. METHODS: High-resolution MRI (T1-, T2, and multiple echo T2*-weighted imaging and fasting lipid levels were obtained from 40 patients with PD and 29 healthy controls. Iron content was estimated from mean R2* values (R2* = 1/T2* calculated for each nigrostriatal structure including substantia nigra, caudate, putamen, and globus pallidus. This was correlated with serum cholesterol levels after controlling for age, gender, and statin use. RESULTS: In patients with PD, higher serum cholesterol levels were associated with lower iron content in the substantia nigra (R = -0.43, p = 0.011 for total-cholesterol, R = -0.31, p = 0.080 for low-density lipoprotein and globus pallidus (R = -0.38, p = 0.028 for total-cholesterol, R = -0.27, p = 0.127 for low-density lipoprotein, but only a trend toward significant association of higher total-cholesterol with lower iron content in the striatum (R = -0.34, p = 0.052 for caudate; R = -0.32, p = 0.061 for putamen. After adjusting for clinical measures, the cholesterol-iron relationships held or became even stronger in the substantia nigra and globus pallidus, but weaker in the caudate and putamen. There was no significant association between serum cholesterol levels and nigrostriatal iron content for controls. CONCLUSIONS: The data show that higher serum total-cholesterol concentration is associated with lower iron content in substantia nigra and globus pallidus in Parkinson's disease patients. Further studies should investigate whether this is mechanistic or epiphenomenological relationship.

    The topic of this book is the following optimisation problem: given a set of discrete variables and a set of functions, each depending on a subset of the variables, minimise the sum of the functions over all variables. This fundamental research problem has been studied within several different contexts of discrete mathematics, computer science and artificial intelligence under different names: Min-Sum problems, MAP inference in Markov random fields (MRFs) and conditional random fields (CRFs), Gibbs energy minimisation, valued constraint satisfaction problems (VCSPs), and, for two-state variabl

    To explore the reliability and feasibility of blood oxygenation level-dependent-based functional magnetic resonance imaging (BOLD-fMRI) to depict hypoxia in breast invasive ductal carcinoma. A total of 103 women with 104 invasive ductal carcinomas (IDCs) underwent breast BOLD-fMRI at 3.0 T. Histological specimens were analysed for tumour size, grade, axillary lymph nodes and expression of oestrogen receptors, progesterone receptors, human epidermal growth factor receptor 2, p53, Ki-67 and hypoxia inducible factor 1{alpha} (HIF-1{alpha}). The distribution and reliability of R2* were analysed. Correlations of the R2* value with the prognostic factors and HIF-1{alpha} were respectively analysed. The R2* map of IDC demonstrated a relatively heterogeneous signal. The mean R2* value was (53.4 {+-} 18.2) Hz. The Shapiro-Wilk test (W = 0.971, P = 0.020) suggested that the sample did not follow a normal distribution. The inter-rater and intrarater correlation coefficient was 0.967 and 0.959, respectively. The R2* values of IDCs were significantly lower in patients without axillary lymph nodes metastasis. The R2* value had a weak correlation with Ki67 expression (r = 0.208, P = 0.038). The mean R2* value correlated moderately with the level of HIF-1{alpha} (r = 0.516, P = 0.000). BOLD-fMRI is a simple and non-invasive technique that yields hypoxia information on breast invasive ductal carcinomas. (orig.)

    evaluated with life satisfaction. We nd that the mapping from changes in earnings to life satisfaction mimics the predicted S-curve remarkably well when the reference point is generated from individuals' past earnings. This nding is robust to a large set of alternative specications. In congruence...... with experimental evidence, we nd that earnings losses have around 2 times greater impact on life satisfaction than earnings gains. We emphasize that the S-curve we nd need not be causal, since the changes in earnings were based on observational data. However, we can rule out that certain other factors produced...

    A considerable amount of studies highlight positive assortative mating in terms of various aspects of mate value. However, there is a lack of studies that directly show how both partners' mate value and mate value differences are related to the satisfaction in heterosexual relationship. In the present study, the authors focused on women and analyzed how their mate value self-assessment and perception of their partners' mate value are related to female relationship satisfaction. The authors also classified them under 3 categories of couples defined by partners' mate value discrepancy, that is, in which a woman has higher, lower, and equal mate value than does her male partner. Women's relationship satisfaction was positively related to the perception of their partners' mate value but negatively correlated to their mate value self-assessment. Moreover, relationship satisfaction was the lowest in the category where woman has higher self-assessed mate value. The level of women's relationship satisfaction did not differ in 2 other categories of relationships. Our results suggest that women's perception of mate value and mate value asymmetry may significantly affect women's satisfaction from their relationships. The authors provide several possible, evolutionary-based explanatory mechanisms.

  8. DARHUBER: A Computer Program for Effect Size Estimation in Linear Regression and for Calculating the Significance of Difference between Observed and Expected R2 Values

    2016-01-01

    In linear multiple regression it is common practice to test whether the squared multiple correlation co efficient, R2, differs significantly from zero. Although frequently used, this test is misleading because the expected value of R2 is not zero under the null hypothesis that ρ, the population value of the multiple correlation coefficient, equals zero. The non-zero expected value of R2 has implications both for significance testing and effect size estimation involving the squared multipl...

    Full Text Available This paper examines the effect of perceived value and service quality on brand trust directly and indirectly through customer satisfaction. Brand trust can be defined as the relationship between consumers and the corporate that is based on trust and reliability of its performance. Questionnaires were given to guests of three-star hotels in Malang, Indonesia, with 158 surveys returned and 114 valid responses were analyzed. Reliability and validity were examined first, and partial least squares (PLS-SEM analysis was performed to evaluate the determinant coefficient (R2, predictive relevance (Q2, and effect size (f2. Results showed customer satisfaction partially mediates perceived value on brand trust, and fully mediates the relationship between service quality and brand trust. Future research in other developing countries, against different hotel class, with international guests, is recommended. Managerial implications were discussed.

    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.

    We extend the Schmittlein et al. model (1987) of customer lifetime value to include satisfaction. Customer purchases are modeled as Poisson events, and their rates of occurrence depend on the satisfaction of the most recent purchase encounter. Customers purchase at a higher rate when they are satisfied than when they are dissatisfied. A closed-form formula is derived for predicting total expected dollar spending from a customer base over a time period (0, ]. This formula reveals that approxim...

    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.

    Full Text Available This study aims to investigate the effects of utilitarian and hedonic values on young consumers’ satisfaction and behavioral intentions in fast-food and fast-casual restaurant sectors comparatively. Also this study investigates which value component (utilitarian or hedonic is more effective on satisfaction and behavioral intentions. The results show that utilitarian and hedonic values have significant effects on satisfaction and behavioral intentions for both fast-food and fast-casual restaurant sectors. Additionally, satisfaction has an influence on behavioral intentions in fast-food restaurant sector, but does not have a significant effect in fast-casual restaurant sector. Moreover, associations between hedonic value with satisfaction and behavioral intentions are significantly different between fast-food and fast-casual restaurant sectors. On the other hand, associations between utilitarian value with satisfaction and behavioral intentions and association between satisfactions with behavioral intentions are not significantly different between fast-food and fast-casual restaurant sectors.

    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

    Spatially confined atoms have been extensively investigated to model atomic systems in extreme pressures. For the simplest hydrogen-like atoms and isotropic harmonic oscillators, numerous physical quantities have been established with very high accuracy. However, the expectation value of employed the basis expansion method with cut-off Slater-type orbitals to investigate these two confined systems. Accurate values for several low-lying bound states were obtained by carefully examining the convergence with respect to the size of basis. A scaling law for < rn \\rangle was derived and it is used to verify the accuracy of numerical results. Comparison with other calculations show that the present results establish benchmark values for this quantity, which may be useful in future studies.

    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.

    2009-12-01

    Patient satisfaction has become an important indicator of process quality inside hospitals. Even so, the improvement of patient satisfaction cannot simply follow from the implementation of new incentives schemes and organisational arrangements; it also depends on hospitals' cultures and climates. This paper studies the impact of alternative models of organisational climate in hospital wards on patient satisfaction. Data gathered from seven public hospitals in Italy are used to explore this relationship. The theoretical approach adopted is the Competing Value Framework which classifies organisations according to their inward or outward focus and according to the importance assigned to control vs. flexibility. Results show that both a model stressing openness, change and innovation and a model emphasising cohesion and workers' morale are positively related to patient satisfaction, while a model based on managerial control is negatively associated with patient satisfaction.

    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.

    Full Text Available 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.

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 Much has been written about service quality impacts on customer satisfaction. However, little research on this perspective has been carried out in military settings. The aim of this study is to examine the relationship between service quality and customer satisfaction, and moderating effects of perceived value in military medical centre. A survey method was employed and data was collected from customers at medical centers under the administration of Malaysian army organization. Analysis was performed using SmartPLS path model analysis. The results show two important findings: first, the interaction between four service quality components (i.e., tangible, reliability, responsiveness and assurance and customers’ perceived value were significantly correlated with customer satisfaction. Second, the interaction between one service quality component (i.e., tangible were not significantly correlated with customer satisfaction. In overall, this result confirms that effect of tangible, reliability, responsiveness and assurance on customer satisfaction has been moderated by customers’ perceived value. Conversely, effect empathy on customer satisfaction has not been moderated by customers’ perceived value. Further, this study offers discussion, implications and conclusion.

    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.

    Full Text Available This paper concerns the issue of value conflicts in construction organizations. This research was conducted in the Malaysian construction industry to fill the gap in the knowledge in areas of organizational behaviour in the construction industry in terms of the possible effects of conflicts on the job satisfaction of internal construction stakeholders. The conflicts considered are those rooted in differences between personal and organizational values. This research targeted professional project consultants identified as architects, engineers, and quantity surveyors as the internal construction stakeholders in Malaysia. The personal-organizational values and the level of job satisfaction of the stakeholders were assessed using a questionnaire survey. To achieve the research objective, comparative and hierarchical regression analyses were performed. The results generated by the analyses indicated a high level of value conflicts in the construction organizations which significantly and negatively affected job satisfaction of the internal stakeholders. Therefore this research, through investigating the potential effect of value conflicts on the stakeholders’ job satisfaction, reveals the importance of the interaction between personal and organizational values in construction organizations which contributes to the extant literature of organizational behaviour in construction.

    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.

  9. 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.

    Objective To study the feasibility of MRI R2* for measurement of liver iron content ( LIC) in iron overload rabbit compared with the pathological findings and laboratory data, and explore the relationship between R2* and LIC. Materials and Methods 32 adult healthy New Zealand rabbits were randomly divided into four groups, group A(n =8), group B (n = 8 ) , group C ( n = 8 ) and control group ( n = 8 ). Three iron overload groups received intravenous injection of i-ron sucrose of different dose every one week for four weeks. All experimental animals underwent liver Bean with 2D MFGRE sequence by using GE Signa HDx 3. 0 T MR. The R2 * value were measured on R2 * Map with small region of interest (RO1) methods by one observer who had been trained to use the technology proficiently. The liver of experimental animals were sent for LIC assessment immediately after MR scan. SPSS 13.0 for Windows statistical software was used to compare the relationship between R2*value with small ROI methods and LIC. Results (l)The LIC increased with the increased in total dose of iron. (2)There was a significant exponent curve association between the R2 * value and LIC. Curve regression equation of the R2 ' value and LIC was Y = EXP( 1.950 + 16. 200X) ,R =0.894. A weak correlation (R = 0. 186) was displayed in animals with high LJC( above 20.0 mg/g dw).

    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 Inventory, LPI) was negatively correlated with turnover intent (r = 0.317, P Turnover Scale (ATS) (r = 0.099, 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.

    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.

    Ferrara, Sergio; Porrati, Massimo

    2015-01-01

    We formulate $R^2$ pure supergravity as a scale invariant theory built only in terms of superfields describing the geometry of curved superspace. The standard supergravity duals are obtained in both "old" and "new" minimal formulations of auxiliary fields. These theories have massless fields in de Sitter space as they do in their non supersymmetric counterpart. Remarkably, the dual theory of $R^2$ supergravity in the new minimal formulation is an extension of the Freedman model, describing a massless gauge field and a massless chiral multiplet in de Sitter space, with inverse radius proportional to the Fayet-Iliopoulos term. This model can be interpreted as the "de-Higgsed" phase of the dual companion theory of $R+R^2$ supergravity.

    Full Text Available Consumer’s values, Cultural values, Emotional Values and Word of mouth expressiveness, are good predictors for their buying decision satisfaction. In current study sample of 500 was taken to assess the consumer’s buying decision satisfaction in relation to the importance of their values associated with those decisions. This study also reveals how gender influences buying decision satisfaction. Consumer values have a positive and significant impact on buying decision satisfac-tion. While evaluation on the basis of gender and females have more emotional and word of mouth linkages than males, on the contrary to this, males are more concerned with cultural val-ues, and are less expressive and have a tendency to suppress their emotions while making buy-ing decisions.

    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.

    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

    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.

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

    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.

    There is a non-trivial four-derivative extension of the gravitational spectrum that is free of ghosts and phenomenologically viable. It is the so called $R^2$-gravity since it is defined by the only addition of a term proportional to the square of the scalar curvature. Just the presence of this term does not improve the ultraviolet behaviour of Einstein gravity but introduces one additional scalar degree of freedom that can account for the dark matter of our Universe.

    Full Text Available Service and value are the two inseparable concepts in experiential service environment. Service personal value is a concept that is subjectively assessed from a consumer perspective, and is associated with service value, consumer satisfaction and loyalty. In this context, the purpose of this study was to examine the relationships between services personal values, service value, satisfaction, and loyalty. Data were collected from persons (996 receiving services from private hospitals and state hospitals using convenience sampling method. The scales of service personal values, service value, satisfaction and loyalty were adapted from literature. Confirmatory factor analysis (CFA was used to investigate validity and reliability of the scales. Then, a structural equation model (SEM was developed and tested using data with Lisrel 8.80 software. The results of the study indicate significant relationships between services personal values, service value, satisfaction, and loyalty. The results of the study have significant implications as to how well private hospital managers design strategies of health service, satisfaction, and loyalty.

    Understanding healthcare performance from the patient's perspective has attracted more attention from the scholars and practitioners as consumers are becoming the driving force to the innovation of healthcare delivery in the knowledge economy (Morath 2003; Scott 2003). However, most of the studies have been constrained in the methods by which the clinical professionals assess what they perceived as the patient's value. This research attempts to examine the constructs for the conceptualization of patient value and its relationship with patient satisfaction. The results indicate that the providers' skills and knowledge and their respectful communication with the patients are the most important. These attributes followed by the providers' level of empathy and attention and the physical environment factors.

    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.

    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.

    Full Text Available Beyond satisfying needs, customer value is the key to establish and maintain long run relationships. Hence, providing excellent customer value as a driving force of customer relationships management performance plays a key role in gaining sustainable competitive advantage. The aim of this research is to investigate the relationships among dimensions of customer value, customer satisfaction, brand loyalty and customer relationship management performance. Data obtained from customers of thermal hotels in Afyon, was analyzed by using Structural Equation Modeling (SEM. Results reveal that emotional value being the most influential dimension and social value being the least influential one, dimensions of customer value affect customer satisfaction directly by 80%. Besides, it is revealed that customer satisfaction has strong effect on customer relationship management performance and brand loyalty and considerable part of this effect is mediated by the indirect effect of customer value. Thus, we can say that dimensions of customer value has an indirect effect on customer relationship management performance and brand loyalty mediated by customer satisfaction.

    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.

    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.

    Using a perceived reward model of overall job satisfaction, this study utilized a correlational research design with multiple regression analysis to determine the predictive power of extrinsic rewards and intrinsic rewards, collectively and individually, as determinants of overall job satisfaction among registered occupational therapists (OTR) working full-time in ambulatory care settings. The intrinsic rewards (task involvement and task autonomy), collectively and individually, were perceived to be significant overall job satisfaction determinants. General working conditions was the only significant extrinsic reward. Given the demand for OTRs in ambulatory care settings, a better understanding of factors that influence overall job satisfaction among OTRs could prove beneficial in developing appropriate recruitment and retention job design strategies.

    Full Text Available Despite its popularity, the concept of service quality in the marketingliterature is still ambiguously and vaguely defined. Several measurementscales have been proposed, but some of these take into accountonly the method of measurement and ignore the idea that the sameinstrument may not be able to be automatically applied in different industriesor in different cultures. Therefore the purpose of this paperis twofold: first to validate the perceived retail banking service scale inthe case of a small transitional economy of Europe, and second to researchservice quality-customer satisfaction relationship and the role ofperceived value within it. Content validity, face validity, construct validity,convergent validity, discriminant validity as well as nomologicalvalidity were assessed with EFA, CFA and SEM. The present research isthe first attempt to measure the relationships among the concepts researchedin the retailing banking industry in transitional economies inEurope. Therefore, its major finding, that the perceived value variablehas a potential to be mediating variable between perceived quality andcustomer satisfaction relationship in retail banking settings, could be ofinterest also for other researchers in transitional economies in Europeand also for researchers from other environments.

    2014-01-01

    Basic research in the biomedical field generates both knowledge that has a value per se regardless of its possible practical outcome and knowledge that has the potential to produce more practical benefits. 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.

    2016-12-01

    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.

  1. 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.

    Full Text Available Mechanochemical synthesis of submicron R2Fe14B particles with R = Dy, Nd, Pr has been performed successfully via high energy ball milling of rare-earth oxides, iron oxide and boron oxide in the presence of a reducing agent (Ca and a dispersant material (CaO, followed by annealing at 800 - 900 °C. In the R = Nd system, we were able to fabricate particles embedded in a CaO matrix with coercivity (Hc of 10.3 kOe after annealing at 900 °C for 5 min. After washing off the dispersant, the Hc was decreased to below 1 kOe because of hydrogen absorption that leads to the formation of the hydrated R2Fe14BHx phase that has a lower anisotropy. Upon removal of the hydrogen the coercivity was increased to 3.3 kOe. The average size of the Nd2Fe14B particles increases from 100 nm in a sample synthesized at 800 °C to 158 nm at 900 °C. The isotropic Dy2Fe14B particles showed a higher coercivity of 21 kOe in washed samples after annealing at 900 °C for 5 min. An average size of 71 nm is measured in samples synthesized at 800 °C and 107 nm at 900 °C. Fitting the high field M(H measurements in Nd2Fe14B to the law of approach to saturation gave values for the magnetocrystalline anisotropy for the washed sample 2.23 × 107 erg/cm3 and for the vacuum annealed sample 4.15 × 107 erg/cm3, both of which are lower than the bulk values. This would explain the lower values of Hc observed in the particles.

    Full Text Available Emotional communication and economic factors play an important role in having a satisfying relationship and a more successful marriage. 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.

  7. How Previous Visits Shape Trip Quality, Perceived Value, Satisfaction, and Future Behavioral Intentions: The Case of Forest-Based Ecotourism in Sri Lanka

    2013-03-01

    Full Text Available A better understanding on relationships between future behavioural intentions and its antecedents allow ecotourism operators to manipulate their ecotourism products to optimize customer satisfaction, and improve marketing efforts. Although the relationship between previous visits and future behavioural intentions have been previously studied, less attention has been given on understanding the process of how previous visits interact with other key determinants of behavioural intentions such as trip quality, perceived value, and satisfaction to form future behavioural intentions. This study proposes a model to examine the role of previous visits in predicting future behavioural intentions to participate in ecotourism, and the relationship between previous visits and future behavioural intentions is modelled in a quality-satisfaction domain. Results suggest previous visits, trip quality, satisfaction and perceived value as important predictors of ecotourists’ intention to revisit and recommend the destination, as well as their propensity to engage in ecotourism in the future. Trip quality was the most important determinant of future ecotourism behavioural intentions. Implications of the study are discussed in the perspective of ecotourism marketing.

    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.

    2017-01-01

    Objective To obtain a comprehensive understanding of the job opinions of hospital professionals by conducting qualitative analyses of the open comments included in a job satisfaction survey and combining these results with the quantitative results. Design A cross-sectional survey targeting all Lausanne University Hospital professionals was performed in the fall of 2013. Material and methods The survey considered ten job satisfaction dimensions (e.g. self-fulfilment, workload, management, work-related burnout, organisational commitment, intent to stay) and included an open comment section. Computer-assisted qualitative analyses were conducted on these comments. Satisfaction rates on the included dimensions and professional groups were entered as predictive variables in the qualitative analyses. Participants Of 10 838 hospital professionals, 4978 participated in the survey and 1067 provided open comments. Data from 1045 respondents with usable comments constituted the analytic sample (133 physicians, 393 nurses, 135 laboratory technicians, 247 administrative staff, including researchers, 67 logistic staff, 44 psycho-social workers, and 26 unspecified). Results Almost a third of the comments addressed scheduling issues, mostly related to problems and exhaustion linked to shifts, work-life balance, and difficulties with colleagues’ absences and the consequences for quality of care and patient safety. The other two-thirds related to classic themes included in job satisfaction surveys. Although some comments were provided equally by all professional groups, others were group specific: work and hierarchy pressures for physicians, healthcare quality and patient safety for nurses, skill recognition for administrative staff. Overall, respondents’ comments were consistent with their job satisfaction ratings. Conclusion Open comment analysis provides a comprehensive understanding of hospital professionals’ job experiences, allowing better consideration of quality

    The resistor ladder (R/2R) digital-to-analogue converter (DAC) architecture is often used in high performance audio solutions due to its low-noise performance. Even high-end R/2R DACs suffer from static nonlinearity distortions. It was suspected that compensating for these nonlinearities would be possible. It was also suspected that this could improve audio quality in audio systems using R/2R DACs for digital-to-analogue (A/D) conversion. Through the use of models of the resistor ladder archi...

    2012-03-01

    Full Text Available Behavioral intentions have been much discussed in marketing literature. Surprisingly, except for airline industry, few studies have been found in transportation industries. This paper studies the public transport passengers’ behavioral intentions in Jakarta city, especially paratransit’s passengers. This paper explores the relationship between passengers’ behavioral intentions and other latent factors, including satisfaction, perceived value, perceived sacrifice, and service quality. The empirical data were drawn from 339 paratransit’s passengers using questionnaire method. Structural Equation Modeling technique is used to analyze the conceptualized relationship model. The empirical results reveal that perceived value and service quality significantly affect passengers’ behavioral intention. The results also show that perceived value is significantly affected by service quality and perceived sacrifice. From the empirical results, managerial implications are discussed.

    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%), pquality, 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.

Then the cultured cells were labeled with a ferumoxides-protamine sulfate complex. Iron uptake was analyzed with an electron microscope and Prussian blue staining. Agarose gel phantoms containing different amounts of EPCs (0–2.5 × 106 cells per milliliter of 1.0% agarose gel were analyzed with 3.0T R2 and R2* relaxometry. For in vivo tracking, liver injury was induced in healthy C57 mice (female, 6 weeks old, weight 19–20 g by administration of carbon tetrachloride by single intraperitoneal injection. The R2* and R2 mapping of injured and normal livers of C57 mice were conducted by using 3.0T magnetic resonance on Days 0, 1, 4, and 8 after intravenous SPIO-tagged cells transplantation.Results: Electron microscope and Perls Prussian blue stain revealed the efficiency of SPIO particles uptake was more than 95% and no structural changes of labeled cells were found compared with control group. R2 and R2* values were linearly correlated with the number of iron-loaded cells in the agarose gel phantoms, and R2* values were significantly greater than R2 (P<0.01. R2* values in all groups were obviously greater than R2 (P<0.01. The R2* values of the injured livers were greater than normal on Days 1 and 4 (P<0.01. No significant difference of R2 values could be found among the three groups.Conclusion: Quantitative R2* mapping provides a useful method for quantifying intravascular administered SPIO-tagged EPCs homing to

    2011-10-01

    We present traversable, Lorentzian wormholes in the framework of R^{2} gravity. These wormholes are obtained by assuming constant Ricci scalar and trace-less equation of state. The metric is asymptotically RW, and locally that of a Lorentzian wormhole. Dynamics of the cosmological background, as well as the expanding wormhole are discussed. Weak energy condition near the wormhole throat is also examined. It is shown that the positive energy density condition can be satisfied all-over a spacelike hypersurface at large enough cosmological times and small enough, positive cosmological constant.

    2017-04-01

    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.

  2. R + R$^{2}$ gravity as R + backreaction

    CERN Document Server

    Kung, J H

    1995-01-01

    Quadratic theory of gravity is a complicated constraint system. We investigate some consequences of treating quadratic terms perturbatively (higher derivative version of backreaction effects). This approach is shown to overcome some well known problems associated with higher derivative theories, i.e., the physical gravitational degree of freedom remains unchanged from those of Einstein gravity. Using such an interpretation of R + \\beta R^2 gravity, we investigate a classical and Wheeler DeWitt evolution of R + \\beta R^2 gravity for a particular sign of \\beta, corresponding to non- tachyon case. Matter is described by a phenomenological \\rho \\propto a(t)^{-n}. It is concluded that both the Friedmann potential U(a) ( {\\dot a}^2 + 2U(a) = 0 ) and the Wheeler DeWitt potential W(a) (\\left[-{\\partial^2\\over \\partial a^2} + 2W(a)\\right]\\psi (a) =0 ) develop repulsive barriers near a\\approx 0 for n>4 (i.e., p > {1\\over 3}\\rho ). The interpretations is clear. Repulsive barrier in U(a) implies that a contracting FRW un...

    Our hospital has a Housestaff Quality Council that fosters education and mentorship of medical residents for quality improvement methodologies. Medical residents on our council identified non-standardised storage rooms as a source of medical resident inefficiency and dissatisfaction. To improve value-add work, medical residents implemented and evaluated a quality improvement project of storage room supplies using the lean method. Using 5S principle and lean methodology, we designed and implemented a standardised supply cart with physician specific supplies. Between April 2014 and April 2015, 40 random observations (20 residents and 20 nurses) both before and after the standardised supply cart implementation were made. The duration time to locate an item was measured in seconds. The paths taken to locate items were drawn as spaghetti diagrams.

    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.

  3. Inflation in R2 supergravity with non-minimal superpotentials

    G.A. Diamandis

    2015-05-01

    Full Text Available We investigate the cosmological inflation in a class of supergravity models that are generalizations of non-supersymmetric R2 models. Although such models have been extensively studied recently, especially after the launch of the PLANCK and BICEP2 data, the class of models that can be constructed has not been exhausted. In this note, working in a supergravity model that is a generalization of Cecotti's model, we show that the appearance of new superpotential terms, which are quadratic in the superfield Λ that couples to the Ricci supermultiplet, alters substantially the form of the scalar potential. The arising potential has the form of the Starobinsky potential times a factor that is exponential in the inflaton field and dominates for large inflaton values. We show that the well-known Starobinsky inflation scenario is maintained only for unnaturally small fine-tuned values of the coupling describing the Λ2 superpotential terms. A welcome feature is the possible increase of the tensor to scalar ratio r, within the limits set by the new Planck and BICEP2 data.

  5. Dark energy and dimensional transmutation in $R^2$ gravity

    CERN Document Server

    Maggiore, Michele

    2015-01-01

    Recent work has shown that non-local modifications of gravity involving terms such as $m^2R\\Box^{-2}R$ (and no cosmological constant) provide a phenomenologically viable alternative to $\\Lambda$CDM. We discuss the possibility that such non-local terms emerge in the far infrared from the running of the coupling constant associated to the $R^2$ term in higher-derivative gravity, which is asymptotically free in the ultraviolet and strongly coupled in the infrared. In this scenario the mass scale $m$ of the non-local model emerges from dimensional transmutation, similarly to $\\Lambda_{\\rm QCD}$ for strong interactions, leading to a technically natural value of the scale associated to dark energy. We also argue that the emergence of the non-local term can be understood as a dynamical mass generation for the conformal mode, as a response of the vacuum to the strong infrared fluctuations that are generated by the anomaly-induced effective action.

    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.)

  11. Reducing U2R and R2L category false negative rates with support vector machines

    Directory of Open Access Journals (Sweden)

    Maček Nemanja

    2014-01-01

    Full Text Available The KDD Cup '99 is commonly used dataset for training and testing IDS machine learning algorithms. Some of the major downsides of the dataset are the distribution and the proportions of U2R and R2L instances, which represent the most dangerous attack types, as well as the existence of R2L attack instances identical to normal traffic. This enforces minor category detection complexity and causes problems while building a machine learning model capable of detecting these attacks with sufficiently low false negative rate. This paper presents a new support vector machine based intrusion detection system that classifies unknown data instances according both to the feature values and weight factors that represent importance of features towards the classification. Increased detection rate and significantly decreased false negative rate for U2R and R2L categories, that have a very few instances in the training set, have been empirically proven.

  12. Occurrence of exact R 2 inflation in non-local UV-complete gravity

    2016-11-01

    The R + R 2, shortly named " R 2" ("Starobinsky") inflationary model, represents a fully consistent example of a one-parameter inflationary scenario. This model has a "graceful exit" from inflation and provides a mechanism for subsequent creation and final thermalization of the standard matter. Moreover, it produces a very good fit of the observed spectrum of primordial perturbations. In the present paper we show explicitly that the R 2 inflationary spacetime is an exact solution of a range of weakly non-local (quasi-polynomial) gravitational theories, which provide an ultraviolet completion of the R 2 theory. These theories are ghost-free, super-renormalizable or finite at quantum level, and perturbatively unitary. Their spectrum consists of the graviton and the scalaron that is responsible for driving the inflation. Notably, any further extension of the spectrum leads to propagating ghost degrees of freedom. We are aimed at presenting a detailed construction of such theories in the so called Weyl basis. Further, we give a special account to the cosmological implications of this theory by considering perturbations during inflation. The highlight of the non-local model is the prediction of a modified, in comparison to a local R 2 model, value for the ratio of tensor and scalar power spectra r, depending on the parameters of the theory. The relevant parameters are under control to be successfully confronted with existing observational data. Furthermore, the modified r can surely meet future observational constraints.

    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.

    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.

    The purpose of this study was to demonstrate the feasibility of an asymmetric spin echo (ASE) single-shot echo planar imaging (EPI) sequence for the noninvasive quantitative measurement of intrarenal R(2) ' in humans within 20 s. The reproducibility of R(2) ' measurements with the ASE-EPI sequence was assessed in nine healthy young subjects in repeated studies conducted over three consecutive days. Moreover, we also evaluated whether the ASE-EPI sequence-measured R(2) ' reflected the intrarenal oxygenation changes induced by furosemide in another group of normal human subjects (n = 10). Different flow attenuation gradients (b = 0, 40 and 80 s/mm(2) ) were utilized to examine the impact of the intravascular signal contribution on the estimation of intrarenal R(2) '. In the absence of flow dephasing gradients (b = 0 s/mm(2) ), the computed coefficient of variation (CV) of R(2) ' was 21.31 ± 4.52%, and the estimated R(2) ' value decreased slightly, but not statistically significantly (p > 0.05), after the administration of furosemide in the medullary region. However, CV of R(2) ' was much smaller in the presence of flow dephasing gradients (9.68 ± 3.58% with b = 40 s/mm(2) and 10.50 ± 3.62% with b = 80 s/mm(2) ). Moreover, a significant reduction in R(2) ' in the renal medulla was obtained (p R(2) ' measurements did not differ between the b = 40 s/mm(2) and b = 80 s/mm(2) scans, suggesting that small diffusion gradients were sufficient to minimize the intravascular signal contribution. In summary, we have demonstrated that renal R(2) ' can be obtained rapidly using an ASE-EPI sequence. The measurement was highly reproducible and reflected the expected intrarenal oxygenation changes induced by furosemide.

    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.

    Full Text Available The present study analyzes the quality service perception and its relation with the satisfaction for the fast food consumers of hamburgers’ sector of the chain Burger King in Hermosillo, Sonora. By the application of Servperf of Cronin and Taylor methodology and a data regression method, through the coefficient of determination (R2 was determined that the independent variables explain the variability or variance of 82.9% in consumer satisfaction and that the explanatory variable which has the most influence in absolute value over the explained variable is reliability, due to its standardized beta is 0.301, being the highest score among the variables. To achieve the objective of this study, a quantitative and correlation investigation was designed, where data was collected from a survey structured by five dimensions, measured by 22 items. It was applied to a random and representative sample of 385 consumers, with a 95% level confidence and a ±5% of permissible error. An inferential statistical analysis allowed observing a positive relation between consumers’ satisfaction level and quality service. The results showed that Servperf is a valid instrument with psychometric characteristics of high reliability that makes it appropriate to measure quality service. The same way, it was observed an index of service global satisfaction of 69.27%, which according to the scale used implies clients are satisfied with the received service.

    2014-01-01

    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.

    2016-01-01

    We propose to couple the R2 performance measure and Particle Swarm Optimization in order to handle multi/many-objective problems. Our proposal shows that through a well-designed interaction process we could maintain the metaheuristic almost inalterable and through the R2 performance measure we did not use neither an external archive nor Pareto dominance to guide the search. The proposed approach is validated using several test problems and performance measures commonly adopted in the specialized literature. Results indicate that the proposed algorithm produces results that are competitive with respect to those obtained by four well-known MOEAs. Additionally, we validate our proposal in many-objective optimization problems. In these problems, our approach showed its main strength, since it could outperform another well-known indicator-based MOEA. PMID:27656200

  11. Spherical collapse for the Starobinsky $R^2$ model

    CERN Document Server

    Guo, Jun-Qi

    2015-01-01

    Spherical scalar collapse for the Starobinsky $R^2$ model is simulated to explore the black hole and singularity formation scenarios. This model was obtained by considering quantum-gravitational effects and would admit some cases of singularity-free cosmological spacetimes. It is found, however, that in gravitational collapse situations, when the matter field is strong enough, a black hole including central singularity can be formed. The nature of this singularity is examined, and it is seen that near the central singularity gravity dominates the repulsion from the $R^2$ term, so that in some circumstances the Ricci scalar $R$ is pushed to infinity by gravity. Therefore, the semi-classical effects as included here do not avoid the singularity problem in general relativity.

    The R^{2}-gravity contribution to energy loss of a hot plasma due to the gravitational bremsstrahlung is calculated in the linearized theory on the basis of classical Coulomb scattering of plasma constituents in small-angle scattering approximation. The explicit dependence of the gravitational luminosity on the plasma temperature is derived and its relevance to the Einstein gravity is demonstrated. The result when applied to the Sun as a hot plasma, shows very good agreement with available data.

    Zhengzheng Zhang

    2016-09-01

    Full Text Available R2MLwiN is a new package designed to run the multilevel modeling software program MLwiN from within the R environment. It allows for a large range of models to be specified which take account of a multilevel structure, including continuous, binary, proportion, count, ordinal and nominal responses for data structures which are nested, cross-classified and/or exhibit multiple membership. Estimation is available via iterative generalized least squares (IGLS, which yields maximum likelihood estimates, and also via Markov chain Monte Carlo (MCMC estimation for Bayesian inference. As well as employing MLwiN's own MCMC engine, users can request that MLwiN write BUGS model, data and initial values statements for use with WinBUGS or OpenBUGS (which R2MLwiN automatically calls via rbugs, employing IGLS starting values from MLwiN. Users can also take advantage of MLwiN's graphical user interface: for example to specify models and inspect plots via its interactive equations and graphics windows. R2MLwiN is supported by a large number of examples, reproducing all the analyses conducted in MLwiN's IGLS and MCMC manuals.

    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%.

    2011-01-01

    Full Text Available The paper reported that a simple chiral selective interface constructed by (1R, 2R-2-amino-1, 2-diphenyl ethanol had been developed to discriminate tryptophan enantiomers. Cyclic voltammetry (CV and electrochemical impedance spectroscopy (EIS were used for the characteristic analysis of the electrode. The results indicated that the interface showed stable and sensitive property to determine the tryptophan enantiomers. Moreover, it exhibited the better stereoselectivity for L-tryptophan than that for D-tryptophan. The discrimination characteristics of the chiral selective interface for discriminating tryptophan enantiomers, including the response time, the effect of tryptophan enantiomers concentration, and the stability, were investigated in detail. In addition, the chiral selective interface was used to determine the enantiomeric composition of L- and D-tryptophan enantiomer mixtures by measuring the relative change of the peak current as well as in pure enantiomeric solutions. These results suggested that the chiral selective interface has the potential for enantiomeric discrimination of tryptophan enantiomers.

    2014-01-01

    Full Text Available Basic research in the biomedical field generates both knowledge that has a value per se regardless of its possible practical outcome and that has the potential to produce more practical benefits. 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 study shows that basic researchers’ support for soft incentives is such that the transformative value of fundamental investigations can be increased without affecting the spirit of the basic research and scientists’ work satisfaction. After discussing the findings, we suggest a few examples of nudges and discuss one in more detail.

    Ben-Dayan, Ido; Torabian, Mahdi; Westphal, Alexander; Zarate, Lucila

    2014-01-01

    We study a model of inflation with terms quadratic and logarithmic in the Ricci scalar, where the gravitational action is $f(R)=R+\\alpha R^2+\\beta R^2 \\ln R$. These terms are expected to arise from one loop corrections involving matter fields in curved space-time. The spectral index $n_s$ and the tensor to scalar ratio yield $10^{-4}\\lesssim r\\lesssim0.03$ and $0.94\\lesssim n_s \\lesssim 0.99$. i.e. $r$ is an order of magnitude bigger or smaller than the original Starobinsky model which predicted $r\\sim 10^{-3}$. Further enhancement of $r$ gives a scale invariant $n_s\\sim 1$ or higher. Other inflationary observables are $d n_s/d\\ln k \\gtrsim -5.2 \\times 10^{-4},\\, \\mu \\lesssim 2.1 \\times 10^{-8} ,\\, y \\lesssim 2.6 \\times 10^{-9}$. Despite the enhancement in $r$, if the recent BICEP2 measurement stands, this model is disfavoured.

    2014-01-01

    The massive star-forming region Mon R2 hosts the closest ultra-compact HII region that can be spatially resolved with current single-dish telescopes. We used the IRAM-30m telescope to carry out an unbiased spectral survey toward two important positions (namely IF and MP2), in order to studying the chemistry of deuterated molecules toward Mon R2. We found a rich chemistry of deuterated species at both positions, with detections of C2D, DCN, DNC, DCO+, D2CO, HDCO, NH2D, and N2D+ and their corresponding hydrogenated species and isotopologs. Our high spectral resolution observations allowed us to resolve three velocity components: the component at 10 km/s is detected at both positions and seems associated with the layer most exposed to the UV radiation from IRS 1; the component at 12 km/s is found toward the IF position and seems related to the molecular gas; finally, a component at 8.5 km/s is only detected toward the MP2 position, most likely related to a low-UV irradiated PDR. We derived the column density of ...

    We study the primordial magnetic field generated by the simple model $f^2 FF$ in Starobinsky, $R^2$-inflationary, model. The scale invariant PMF is achieved at relatively high power index of the coupling function, $\\left| \\alpha \\right| \\approx 7.44$. This model does not suffer from the backreaction problem as long as, the rate of inflationary expansion, $H$, is in the order of or less than the upper bound reported by Planck ($\\le 3.6 \\times 10^{-5} M_\\rm{Pl}$) in both de Sitter and power law expansion, which show similar results. We calculate the lower limit of the reheating parameter, $R_\\rm{rad} > 6.888$ in $R^2$-inflation. Based on the upper limit obtained from CMB, we find that the upper limits of magnetic field and reheating energy density as, $\\left(\\rho_{B_\\rm{end}} \\right)_\\rm{CMB} < 1.184 \\times 10^{-20} M_\\rm{Pl}^4$ and $\\left(\\rho_\\rm{reh} \\right)_\\rm{CMB} < 8.480 \\times 10^{-22} M_\\rm{Pl}^4$.

    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.

    2010-01-01

    Background The purpose of this study was to reduce the number of items, create a scoring method and assess the psychometric properties of the Freedom from Glasses Value Scale (FGVS), which measures benefits of freedom from glasses perceived by cataract and presbyopic patients after multifocal intraocular lens (IOL) surgery. Methods The 21-item FGVS, developed simultaneously in French and Spanish, was administered by phone during an observational study to 152 French and 152 Spanish patients who had undergone cataract or presbyopia surgery at least 1 year before the study. Reduction of items and creation of the scoring method employed statistical methods (principal component analysis, multitrait analysis) and content analysis. Psychometric properties (validation of the structure, internal consistency reliability, and known-group validity) of the resulting version were assessed in the pooled population and per country. Results One item was deleted and 3 were kept but not aggregated in a dimension. The other 17 items were grouped into 2 dimensions ('global evaluation', 9 items; 'advantages', 8 items) and divided into 5 sub-dimensions, with higher scores indicating higher benefit of surgery. The structure was validated (good item convergent and discriminant validity). Internal consistency reliability was good for all dimensions and sub-dimensions (Cronbach's alphas above 0.70). The FGVS was able to discriminate between patients wearing glasses or not after surgery (higher scores for patients not wearing glasses). FGVS scores were significantly higher in Spain than France; however, the measure had similar psychometric performances in both countries. Conclusions The FGVS is a valid and reliable instrument measuring benefits of freedom from glasses perceived by cataract and presbyopic patients after multifocal IOL surgery. PMID:20497555

    We evaluate quantum gravity corrections to the standard model Higgs potential $V(\\phi)$ a la Coleman-Weinberg and examine the stability question of $V(\\phi)$ at scales of Planck mass $M_{\\rm Pl}$. We compute the gravity one-loop corrections by using the momentum cut-off in Einstein gravity. The gravity corrections affect the potential in a significant manner for the value of $\\Lambda= (1 - 3)M_{\\rm Pl}.$ In view of reducing the UV cut-off dependence we also make a similar study in the $R^2$ gravity.

    The aim of this study was to examine the use of R2* mapping in maternal and fetal sub-regions of the placenta with the aim of providing a reference for blood oxygenation levels during normative development. There have been a number of MR relaxation studies of placental tissues in-utero, but none have reported R2* value changes with age, or examined differences in sub-regions of the placenta. Here specialized long-duration Multi-frame R2* imaging was used to create a stable estimate for R2* values in different placental regions in healthy pregnant volunteers not imaged for clinical reasons. 27 subjects were recruited and scanned up to 3 times during their pregnancy. A multi-slice dual echo EPI based BOLD acquisition was employed and repeated between 90 and 150 times over 3 to 5 minutes to provide a high accuracy estimate of the R2* signal level. Acquisitions were also repeated in 13 cases within a visit to evaluate reproducibility of the method in a given subject. Experimental results showed R2* measurements were highly repeatable within a visit with standard deviation of (0.76). Plots of all visits against gestational age indicated clear correlations showing decreases in R2* with age. This increase was consistent was also consistent over time in multiple visits of the same volunteer during their pregnancy. Maternal and fetal regional changes with gestational age followed the same trend with increase in R2* over the gestational age.

    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...

    Full Text Available Higher education institutions as equal participants in the contemporary market operations are intended to deliver value to its customers through improving the overall institutional performance. Factors and trends in the environment have a major impact on higher education and have significant implications for the quality of educational services. For many institutions of higher education, student satisfaction has remained 'trapped' in the departments where the acceptance and enrollment of freshmen was taking place. But the appearance of the Bologna Declaration initiated the need for the existence of a model of student satisfaction in order to control rates of student satisfaction (regarding education services, institutions, relationships, marketing and alumni activities. The quality of educational services through students' satisfaction and attitudes can be monitored by different methods / models of student satisfaction. The method of interviewing is the most common, but modern models suggest the need for consideration of various factors and aspects simultaneously.

    Edwards, Jeffrey R; Cable, Daniel M

    2009-05-01

    Research on value congruence has attempted to explain why value congruence leads to positive outcomes, but few of these explanations have been tested empirically. In this article, the authors develop and test a theoretical model that integrates 4 key explanations of value congruence effects, which are framed in terms of communication, predictability, interpersonal attraction, and trust. These constructs are used to explain the process by which value congruence relates to job satisfaction, organizational identification, and intent to stay in the organization, after taking psychological need fulfillment into account. Data from a heterogeneous sample of employees from 4 organizations indicate that the relationships that link individual and organizational values to outcomes are explained primarily by the trust that employees place in the organization and its members, followed by communication, and, to a lesser extent, interpersonal attraction. Polynomial regression analyses reveal that the relationships emanating from individual and organizational values often deviated from the idealized value congruence relationship that underlies previous theory and research. The authors' results also show that individual and organizational values exhibited small but significant relationships with job satisfaction and organizational identification that bypassed the mediators in their model, indicating that additional explanations of value congruence effects should be pursued in future research.

    Full Text Available Objective. To investigate the value of BOLD-based reversible transverse relaxation rate (R2′ MRI in detecting ischemic penumbra (IP in a monkey model of reversible middle cerebral artery occlusion (MCAO and time evolution of relative R2′ (rR2′ in infarcted core, IP, and oligemia. Materials and Methods. 6 monkeys were used to make MCAO by the microcatheter method. MR scans were performed at 0 h (1 h after MCAO, 1 h, 3 h, 6 h, 12 h, 24 h, and 48 h after reperfusion. R2′ was calculated using quantitative T2 and T2∗ maps. Ischemic area was subdivided into infracted core, IP and oligemia. rR2′ was calculated respectively. Results. Reversible MCAO model for 4/6 monkeys was made successfully. rR2values were significantly different at each time point, being highest in oligemia followed by IP and infarcted core (<.05. With reperfusion time evolution, rR2′ in infarcted core showed a decreased trend: sharply decreased within 6 hours and maintained at 0 during 6–48 hours (<.05. rR2values in IP and oligemia showed similar increased trend: sharply increased within 6 hours, maintained a plateau during 6–24 hours, and slightly increased until 48 hours. Conclusion. BOLD-based R2′ MRI can be used to describe changes of cerebral oxygen extract in acute ischemic stroke, and it can provide additional information in detecting IP. The time evolution rR2′ in infarcted core, IP, and oligemia is in accordance with the underlying pathophysiology.

    We report the first detection of the reactive ions CO+ and HOC+ towards ultracompact (UC) HII regions, particularly in Mon R2 and G29.96-0.02. We have observed two positions in Mon R2, namely the peak of the UC HII region and a position in the high density molecular cloud which bounds it. CO+ and HOC+ were detected at the UC HII region but not at the molecular cloud, as expected if the CO$^+$ and HOC$^+$ emissions arise in the PDR surrounding the \\uch. The measured CO$^+$ and HOC$^+$ column densities are of the order of 10$^{11}$ cm$^{-2}$ in both sources, which yields a strikingly low [HCO$^+$]/[HOC$^+$] abundance ratio of 460 in Mon R2. These values are similar to those found in some other well-known PDRs, like NGC 7023 and the Orion Bar. We briefly discuss the chemical implications of these results.

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

    Directory of Open Access Journals (Sweden)

    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

    Based on customer satisfaction theory and attribution theory,the author builds a customer satisfaction model. An empirical study was made on ways that influence consumer satisfaction according to survey data of customers in Beijing, Shanghai,Guangzhou,Wuhan,Zhengzhou and Xi'an. Research shows that the value of goods has a positive direct impact on customer satisfaction,while cost of goods has a direct negative impact on consumer satisfaction. The value of goods and cost of goods enlarge and strengthen the impact on customer satisfaction through the positive role of intermediate variables,such as satisfaction of commodities and service quality. Analysis shows that consumers need not only desirable commodity,but also satisfactory service. Therefore,in order to win customer satisfaction,enterprises should provide good products and great service at the same time.%基于消费者满意度理论和归因理论,构建了消费者满意度模型,采用对北京、上海、广州、武汉、郑州和西安6个城市消费者的调查数据,对影响消费者满意度的路径进行了实证研究。研究表明,商品价值对消费者满意度具有正向直接影响,商品成本对消费者满意度具有负向直接影响,商品价值和商品成本又通过中间变量商品满意度和服务质量的正向中介作用进而使其对消费者满意度的影响得以放大和强化;分析表明,消费者不仅需要中意的商品,更希望得到满意的服务,企业要想赢得消费者满意,应把商品和服务同时做好。

    We used a Web-based evaluation system to institute specific changes to various clinical teaching services in our integrated residency in an effort to optimize the overall quality of the educational experience and measured the resident satisfaction in these rotations. Residents rated 8 categories of experience on a scale of 1 to 5 (maximum summation score, 40 points). Data were analyzed by t-test for equality of means. A probability value of less than.05 was considered significant. Compliance with completion of the evaluations was 100%. The Chronbach's alpha reliability coefficient of the tool was 0.826. Tukey's estimate of power to achieve additivity was 1.5. Six under-performing services were re-engineered with prominent effects on 7 postgraduate year (PGY) rotations. On 2 general surgery services at 1 hospital, the workload was redistributed, and a dedicated team teaching time was instituted (PGY-3 [a]: before, 22 points/after, 31 points; P =.003; PGY-3 [b]: before, 25 points/after, 31 points; P =.004; PGY-1: before, 24 points/after, 29 points; P =.07). A general surgery service at another hospital redistributed coverage of the attending surgeons to create a nonteaching service (PGY-1: before, 22 points/-after, 27 points; P =.01). The transplantation service (PGY-3) was examined, and the role of the point was redefined (before, 24 points/after, 31 points; P =.01). One vascular service (PGY-2) redistributed cases and workload (before, 27 points/after, 22 points; P =.07). The vascular PGY-2 position was eliminated and replaced by a mid-level practitioner. The cardiothoracic service (PGY-1) rotation was converted into a preceptorship (before, 23 points/after, 30 points; P =.015). A web-based clinical rotation evaluation provides a means for the assessment of the impact of programmatic changes while preserving resident anonymity and maintaining accountability.

    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.

    A bacterial strain R-2, capable of degrading fipronil, was isolated from a long-term fipronil-polluted activated sludge in a fipronil manufacture factory. Strain R-2 was preliminarily identified as Paracoccus sp. based on its physiological and biochemical properties, as well as the 16S rRNA gene sequence analysis. Strain R-2 could utilize fipronil as the sole carbon source for growth, and degrade 85% of 50 mg/L fipronil within 3 d in mineral salts medium. The optimal pH value and temperature for fipronil degradation by strain R-2 were 6.0-7.0 and 30 ℃, respectively. The degrading rate showed a negative correlation with the initial concentration of fipronil. The addition of 0.1 mmol/L Zn2+or Fe3+ to the culture medium could significantly increase the degradation of fipronil. In both sterile and non-sterile soils, strain could remove 63.4%-71.2% of 100 μg/g fipronil within 10 d.%从长期受锐劲特污染的农药厂活性污泥中分离到一株锐劲特降解菌株R-2,根据其生理生化特征和16S rRNA基因序列同源性分析.将该菌株鉴定为Paracoccus sp..菌株R-2能以锐劲特为唯一碳源生长,在含有50 mg/L的锐劲特的基础盐培养基中,3 d的降解率达到85%.菌株R-2降解锐劲特的最适温度为30℃,最适pH值为6.0-7.0,其降解锐劲特的效率与锐劲特初始浓度呈负相关.添加0.1 mmol/L的Zn或Fe能够显著促进菌株对锐劲特的降解.灭菌与非灭菌土壤降解试验表明,菌株R-2均可以在10 d内降解63.4%-71.2%的100 μg/g的锐劲特.

    Multi-center studies are advantageous for enrolling participants of varying pathological and demographical conditions, and especially in neurological studies. Hence stability of the obtained quantitative R2* and susceptibility in multicenter studies is a key issue for their widespread applications. In this work, the stabilities of simultaneously obtained R2* and susceptibility are investigated and compared across 10 sites that are equipped with the same scanner and receiver coil, the same post-processing process was used to achieve consistent experiment setup. Two healthy adult volunteers (one male and female) participated in this study. High intraclass correlation coefficient was obtained for both susceptibility (0.94) and R2* (0.96). The coefficients of variance for all measurements obtained were smaller than 0.1, the largest variations of measurements in all the chosen ROIs fall within ±20% from the median value. Higher level of stability was obtained in R2* as compared to susceptibility at 1 mm resolution (P < 0.05) and at 1.5 mm (P < 0.01). PMID:28349957

    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.

    实证研究表明,在中国物流业中,服务质量对客户忠诚有直接的驱动作用,并通过客户价值对客户忠诚产生间接驱动作用,但不能通过客户满意对客户忠诚产生影响;情感因素对客户忠诚的形成不起作用,客户价值对服务质量与客户忠诚之间的关系具有调节效应。因此,企业应不断提升自身的服务质量,提升客户价值,避免陷入“满意误区”,把握客户的需求或关注点,从需求的角度设计和传递服务质量。%In China’s logistics industry,service quality has not only a direct but also an indirect impact through customer value on customer loyalty,whereas customer satisfactory has no significant mediating effect among them. The emotional factors have no impacts on customer loyalty;and customer value has the mediating effect on the relationship between service quality and customer loyalty. So,the enterprises should continuously improve their own service quality,improve customer value,avoid the misunderstanding on satisfaction,understand more about the customers’needs and focus,and design and deliver service quality from the angle of needs.

    To develop quantitative susceptibility mapping (QSM) of bone using an ultrashort echo time (UTE) gradient echo (GRE) sequence for signal acquisition and a bone-specific effective transverse relaxation rate ( R2*) to model water-fat MR signals for field mapping. Three-dimensional radial UTE data (echo times ≥ 40 μs) was acquired on a 3 Tesla scanner and fitted with a bone-specific signal model to map the chemical species and susceptibility field. Experiments were performed ex vivo on a porcine hoof and in vivo on healthy human subjects (n = 7). For water-fat separation, a bone-specific model assigning R2* decay mostly to water was compared with the standard models that assigned the same decay for both fat and water. In the ex vivo experiment, bone QSM was correlated with CT. Compared with standard models, the bone-specific R2* method significantly reduced errors in the fat fraction within the cortical bone in all tested data sets, leading to reduced artifacts in QSM. Good correlation was found between bone CT and QSM values in the porcine hoof (R(2)  = 0.77). Bone QSM was successfully generated in all subjects. The QSM of bone is feasible using UTE with a conventional echo time GRE acquisition and a bone-specific R2* signal model.

    As a critical step toward understanding the role of abnormal intracellular Ca(2+) release via the ryanodine receptor (RyR(2)) during the development of hypertension-induced cardiac hypertrophy and heart failure, this study examines two questions: 1) At what stage, if ever, in the development of hypertrophy and heart failure is RyR(2) hyperphosphorylated at Ser(2808)? 2) Does the spatial distribution of RyR(2) clusters change in failing hearts? Using a newly developed semiquantitative immunohistochemistry method and Western blotting, we measured phosphorylation of RyR(2) at Ser(2808) in the spontaneously hypertensive rat (SHR) at four distinct disease stages. A major finding is that hyperphosphorylation of RyR(2) at Ser(2808) occurred only at late-stage heart failure in SHR, but not in age-matched controls. Furthermore, the spacing between RyR(2) clusters was shortened in failing hearts, as predicted by quantitative model simulation to increase spontaneous Ca(2+) wave generation and arrhythmias.

    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.

  4. 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.

    Eugenol is a volatile phenylpropanoid that contributes to flower and ripe fruit scent. In ripe strawberry (Fragaria × ananassa) fruit receptacles, eugenol is biosynthesized by eugenol synthase (FaEGS2). However, the transcriptional regulation of this process is still unknown. We have identified and functionally characterized an R2R3 MYB transcription factor (emission of benzenoid II [FaEOBII]) that seems to be the orthologous gene of PhEOBII from Petunia hybrida, which contributes to the regulation of eugenol biosynthesis in petals. The expression of FaEOBII was ripening related and fruit receptacle specific, although high expression values were also found in petals. This expression pattern of FaEOBII correlated with eugenol content in both fruit receptacle and petals. The expression of FaEOBII was repressed by auxins and activated by abscisic acid, in parallel to the ripening process. In ripe strawberry receptacles, where the expression of FaEOBII was silenced, the expression of cinnamyl alcohol dehydrogenase1 and FaEGS2, two structural genes involved in eugenol production, was down-regulated. A subsequent decrease in eugenol content in ripe receptacles was also observed, confirming the involvement of FaEOBII in eugenol metabolism. Additionally, the expression of FaEOBII was under the control of FaMYB10, another R2R3 MYB transcription factor that regulates the early and late biosynthetic genes from the flavonoid/phenylpropanoid pathway. In parallel, the amount of eugenol in FaMYB10-silenced receptacles was also diminished. Taken together, these data indicate that FaEOBII plays a regulating role in the volatile phenylpropanoid pathway gene expression that gives rise to eugenol production in ripe strawberry receptacles.

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

    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.

    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.

    We present a near-infrared extinction map of a large region (approximately 2200 deg^2) covering the Orion, the Monoceros R2, the Rosette, and the Canis Major molecular clouds. We used robust and optimal methods to map the dust column density in the near-infrared (NICER and NICEST) towards ~19 million stars of the Two Micron All Sky Survey (2MASS) point source catalog. Over the relevant regions of the field, we reached a 1-sigma error of 0.03 mag in the K-band extinction with a resolution of 3 arcmin. We measured the cloud distances by comparing the observed density of foreground stars with the prediction of galactic models, thus obtaining d_{Orion A} = (371 +/- 10) pc, d_{Orion B} = (398 +/- 12) pc, $d_{Mon R2} = (905 +/- 37) pc, $d_{Rosette} = (1330 +/- 48) pc, and $d_{CMa} = (1150 +/- 64) pc, values that compare very well with independent estimates.

    The Eysenck Personality Questionnaire's (EPQ) N value (neuroticism) was used to evaluate information from 158 patients before ceramic crown treatment. Patient satisfaction was also evaluated using a satisfaction questionnaire 2 weeks post treatment. Patient expectations were not correlated with sex, age, or N value, and sex was not correlated with patient satisfaction other than in relation to crown shape. Total esthetic satisfaction and feature improvement were positively correlated with age, while satisfaction for five specific criteria was negatively correlated with N value and overall expectation. These observations underscore the importance of considering the physical and psychologic aspects of patient care when planning dental treatment.

    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.

    The type 2 ryanodine receptor (RyR2) is a Ca2+ release channel on the endoplasmic reticulum (ER) of several types of cells, including cardiomyocytes and pancreatic β cells. In cardiomyocytes, RyR2-dependent Ca2+ release is critical for excitation-contraction coupling; however, a functional role for RyR2 in β cell insulin secretion and diabetes mellitus remains controversial. Here, we took advantage of rare RyR2 mutations that were identified in patients with a genetic form of exercise-induced sudden death (catecholaminergic polymorphic ventricular tachycardia [CPVT]). As these mutations result in a "leaky" RyR2 channel, we exploited them to assess RyR2 channel function in β cell dynamics. We discovered that CPVT patients with mutant leaky RyR2 present with glucose intolerance, which was heretofore unappreciated. In mice, transgenic expression of CPVT-associated RyR2 resulted in impaired glucose homeostasis, and an in-depth evaluation of pancreatic islets and β cells from these animals revealed intracellular Ca2+ leak via oxidized and nitrosylated RyR2 channels, activated ER stress response, mitochondrial dysfunction, and decreased fuel-stimulated insulin release. Additionally, we verified the effects of the pharmacological inhibition of intracellular Ca2+ leak in CPVT-associated RyR2-expressing mice, in human islets from diabetic patients, and in an established murine model of type 2 diabetes mellitus. Taken together, our data indicate that RyR2 channels play a crucial role in the regulation of insulin secretion and glucose homeostasis.

    The single 2 dilation orthogonal wavelet multipliers in one dimensional case and single A-dilation (where A is any expansive matrix with integer entries and|detA|=2) wavelet multipliers in high dimensional case were completely characterized by the Wutam Consortium (1998) and Z. Y. Li, et al. (2010). But there exist no more results on orthogonal multivariate wavelet matrix multipliers corresponding integer expansive dilation matrix with the absolute value of determinant not 2 in L2(R2). In this paper, we choose as the dilation matrix and consider the 2I2-dilation orthogonal multivariate wavelet Y={y1,y2,y3}, (which is called a dyadic bivariate wavelet) multipliers. We call the 3×3 matrix-valued function A(s)=[ fi,j(s)]3×3, where fi,j are measurable functions, a dyadic bivariate matrix Fourier wavelet multiplier if the inverse Fourier transform of A(s)(cy1(s),cy2(s),cy3(s))⊤ = ( b g1(s), b g2(s), b g3(s))⊤ is a dyadic bivariate wavelet whenever (y1,y2,y3) is any dyadic bivariate wavelet. We give some conditions for dyadic matrix bivariate wavelet multipliers. The results extended that of Z. Y. Li and X. L. Shi (2011). As an application, we construct some useful dyadic bivariate wavelets by using dyadic Fourier matrix wavelet multipliers and use them to image denoising.

    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

    Full Text Available Orientation: There is much research on extrinsic motivation, job satisfaction and life satisfaction in organisations. However, empirical evidence on how such factors affect employees in public organisations in developing countries is lacking.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.

    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

    Full Text Available Introduction: Organizational climate is a perception of the organization's members about their organization and it will be able to influence their attitude. Conducive organizational climate is important to improve job satisfaction. Nurse's job satisfaction is needed to increase quality of health service care. The purpose of the study is to analyze the correlation between organizational climate and job satisfaction of nurse. Method: This study was a quantitative research that used a descriptive method with cross sectional survey design. The population was all nurses in IRNA Bedah of RSUD Kabupaten Sampang that consists of 15 people. The sample were 11 people recruited by using purposive sampling. The data was collected by using organizational climate questionnaire and job satisfaction questionnaire, interval scale was used with Likert scoring. The statistic analysis used Spearman's rho and content analysis. Result: The result of the statistic test shows that organizational climate had p = 0.003 which reveals that there was a correlation between organizational climate and job satisfaction of nurse in IRNA Bedah of RSUD Kabupaten Sampang, with r2 = 0.799 (within a range 0.60–0.799. It means that both variable had a strong positive correlation. Discussion: In conclusion, there was a positive correlation between organizational climate and job satisfaction with strong correlation. The writer suggests the next researchers to study dimension of organizational climate from Pines (1982, and factors to influence job satisfaction from McClelland (1962 so that they will be able to compare the correlation between organizational climate and job satisfaction by using another theory.

  16. How do uncertainties in NCEP R2 and CFSR surface fluxes impact tropical ocean simulations?

    2017-01-01

    NCEP/DOE reanalysis (R2) and Climate Forecast System Reanalysis (CFSR) surface fluxes are widely used by the research community to understand surface flux climate variability, and to drive ocean models as surface forcings. However, large discrepancies exist between these two products, including (1) stronger trade winds in CFSR than in R2 over the tropical Pacific prior 2000; (2) excessive net surface heat fluxes into ocean in CFSR than in R2 with an increase in difference after 2000. The goals of this study are to examine the sensitivity of ocean simulations to discrepancies between CFSR and R2 surface fluxes, and to assess the fidelity of the two products. A set of experiments, where an ocean model was driven by a combination of surface flux components from R2 and CFSR, were carried out. The model simulations were contrasted to identify sensitivity to different component of the surface fluxes in R2 and CFSR. The accuracy of the model simulations was validated against the tropical moorings data, altimetry SSH and SST reanalysis products. Sensitivity of ocean simulations showed that temperature bias difference in the upper 100 m is mostly sensitive to the differences in surface heat fluxes, while depth of 20 °C (D20) bias difference is mainly determined by the discrepancies in momentum fluxes. D20 simulations with CFSR winds agree with observation well in the western equatorial Pacific prior 2000, but have large negative bias similar to those with R2 winds after 2000, partly because easterly winds over the central Pacific were underestimated in both CFSR and R2. On the other hand, the observed temperature variability is well reproduced in the tropical Pacific by simulations with both R2 and CFSR fluxes. Relative to the R2 fluxes, the CFSR fluxes improve simulation of interannual variability in all three tropical oceans to a varying degree. The improvement in the tropical Atlantic is most significant and is largely attributed to differences in surface winds.

    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.

    Over the last few years, most health care facilities have become intensely aware of the need to increase patient satisfaction. However, with today's more consumer-driven market, this can be a daunting task for even the most experienced health care manager. Recent studies indicate that focusing on employee satisfaction and subsequent employee retention may be strong catalysts to patient satisfaction. This study offers a review of how employee satisfaction and retention correlate with patient satisfaction and also examines the current ways health care organizations are focusing on employee satisfaction and retention.

    Catecholaminergic polymorphic ventricular tachycardia is a malignant disease, due to mutations in proteins controlling Ca(2+) homeostasis. While the phenotype is characterized by polymorphic ventricular arrhythmias under stress, supraventricular arrhythmias may occur and are not fully characterized. Twenty-five relatives from a Spanish family with several sudden deaths were evaluated with electrocardiogram, exercise testing, and optional epinephrine challenge. Selective RyR2 sequencing in an affected individual and cascade screening in the rest of the family was offered. The RyR2(R420Q) mutation was generated in HEK-293 cells using site-directed mutagenesis to conduct in vitro functional studies. The exercise testing unmasked catecholaminergic polymorphic ventricular tachycardia in 8 relatives (sensitivity = 89%; positive predictive value = 100%; negative predictive value = 93%), all of them carrying the heterozygous RyR2(R420Q) mutation, which was also present in the proband and a young girl without exercise testing, a 91% penetrance at the end of the follow-up. Remarkably, sinus bradycardia, atrial and junctional arrhythmias, and/or giant post-effort U-waves were identified in patients. Upon permeabilization and in intact cells, the RyR2(R420Q) expressing cells showed a smaller peak of Ca(2+) release than RyR2 wild-type cells. However, at physiologic intracellular Ca(2+) concentration, equivalent to the diastolic cytosolic concentration, the RyR2(R420Q) released more Ca(2+) and oscillated faster than RyR2 wild-type cells. The missense RyR2(R420Q) mutation was identified in the N-terminus of the RyR2 gene in this highly symptomatic family. Remarkably, this mutation is associated with sinus bradycardia, atrial and junctional arrhythmias, and giant U-waves. Collectively, functional heterologous expression studies suggest that the RyR2(R420Q) behaves as an aberrant channel, as a loss- or gain-of-function mutation depending on cytosolic intracellular Ca(2

    One might expect Kristin Baird, RN, MHA, the author of a book about customer service in health care and vice president of business development at the small central Wisconsin health system Watertown Area Health Services, to know the value of measuring patient satisfaction. That assumption is correct. And since the system and its hospital, five clinics, and two senior housing complexes already engage in external benchmarking of financial and quality indicators, you might expect that they did the same with patient satisfaction. But here, you'd be wrong.

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

    The diverseness of terminology used in describing ocean data creates a barrier to 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 U.S. 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 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 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 within R2R or are specific to the U.S. The goal of this student project is to crosswalk local/national vocabularies to authoritative international ones, where they exist, or to vocabularies widely used by ODIP partners. Specifically, R2R developed the following crosswalks: UNOLS ports to SeaDataNet Ports Gazetteer, R2R Device Models to NVS SeaVoX Device Catalog, R2R Organizations to the European Directory of Marine Organizations (EDMO), and R2R chief scientist names to well known professional identifiers such as ORCID, Research Gate, Linkedin, etc. Mappings were done in simple spreadsheets using synonymy relationships, and will be published as part of the R2R Linked Data resources. The level of success in crosswalking was variable. All ports are successfully mapped. Both organizations and device models have initial mappings and R2R has added new terms to EDMO and SeaVoX Device Catalog vocabularies allowing for nearly complete coverage of

    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.

    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.

    Full Text Available Increasing in the popularity of regional sport tourism addresses the consumers to measure satisfaction of participants in order to provide high quality product or services. The literature declares the strong need of a reliable and valid scale in the area of sport tourism. For that purpose this paper describes the process of developing Tournament Satisfaction Scale (TOSS that can be used to asses athletes’ perception of satisfaction through sport tournaments. An item pool with 33 items was developed by literature reviews and interviews with experts in the area of sport tourism, sport management and coaching. Exploratory Factor Analysis with Maximum Likelihood extraction method and oblique rotation (direct oblimin was carried out by using the data obtained from 278 athletes in various sport branches participated in a tournament as a regional sport tourist. Exploratory Factor Analysis results yielded one factor with 22 items over .50 factor loading. The 22-item TOSS was found to explain 40.3% of the variance in tournament satisfaction. Cronbach alpha coefficient is 0.93 for TOSS indicating satisfactory reliability evidence. Overall, it can be concluded that the scale is reliable and valid tool for evaluating tournament satisfaction from the perceptions of athletes. In this way coaches, team managers, and tournament organizers would possible to obtain important clues about their performances.

    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.

    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

    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.

    GluR2, an α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor subunit, plays important roles in neuronal survival. We previously showed that exposure of cultured rat cortical neurons to several chemicals decreases GluR2 protein expression, leading to neuronal toxicity. Methoxychlor, the bis-p-methoxy derivative of dichlorodiphenyltrichloroethane, and fenvalerate, a synthetic pyrethroid chemical, have been used commercially as agricultural pesticides in several countries. In this study, we investigated the effects of long-term methoxychlor and fenvalerate exposure on neuronal glutamate receptors. Treatment of cultured rat cortical neurons with 1 or 10 µM methoxychlor and fenvalerate for 9 days selectively decreased GluR2 protein expression; the expression of other AMPA receptor subunits GluR1, GluR3, and GluR4 did not change under the same conditions. Importantly, the decreases in GluR2 protein expression were also observed on the cell surface membrane where AMPA receptors typically function. In addition, both chemicals decreased neuronal viability, which was blocked by pretreatment with 1-naphtylacetylspermine, an antagonist of GluR2-lacking AMPA receptors, and MK-801, an N-methyl-d-aspartate (NMDA) receptor antagonist. These results suggest that long-term exposure to methoxychlor and fenvalerate decreases GluR2 protein expression, leading to neuronal death via overactivation of GluR2-lacking AMPA and NMDA receptors.

    Full Text Available To study sensory processing, stimuli are delivered to the sensory organs of animals and evoked neural activity is recorded downstream. However, noise and uncontrolled modulatory input can interfere with repeatable delivery of sensory stimuli to higher brain regions. Here we show how channelrhodopsin-2 (ChR2 can be used to deliver continuous time-varying currents to neurons at any point along the sensory-motor pathway. To do this, we first deduce the frequency response function of ChR2 using a Markov model of channel kinetics. We confirm ChR2's frequency response characteristics using continuously-varying optical stimulation of neurons that express one of three ChR2 variants. We find that wild-type ChR2 and the E123T/H134R mutant (`CheTA' can pass continuously-varying stimuli with frequencies up to 70 Hz. Additionally, we find that wild-type ChR2 exhibits a strong resonance at 6-10 Hz. Together, these results indicate that ChR2-derived optogenetic tools are useful for delivering highly repeatable artificial stimuli that mimic in-vivo synaptic bombardment.

    Full Text Available Since changes in lung microstructure are important indicators for (early stage lung pathology, there is a need for quantifiable information of diagnostically challenging cases in a clinical setting, e.g. to evaluate early emphysematous changes in peripheral lung tissue. Considering alveoli as spherical air-spaces surrounded by a thin film of lung tissue allows deriving an expression for Carr-Purcell-Meiboom-Gill transverse relaxation rates R2 with a dependence on inter-echo time, local air-tissue volume fraction, diffusion coefficient and alveolar diameter, within a weak field approximation. The model relaxation rate exhibits the same hyperbolic tangent dependency as seen in the Luz-Meiboom model and limiting cases agree with Brooks et al. and Jensen et al. In addition, the model is tested against experimental data for passively deflated rat lungs: the resulting mean alveolar radius of RA = 31.46 ± 13.15 μm is very close to the literature value (∼34 μm. Also, modeled radii obtained from relaxometer measurements of ageing hydrogel foam (that mimics peripheral lung tissue are in good agreement with those obtained from μCT images of the same foam (mean relative error: 0.06 ± 0.01. The model's ability to determine the alveolar radius and/or air volume fraction will be useful in quantifying peripheral lung microstructure.

    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.

    Full Text Available The human aspect in the present context has acquired immense importance. 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.

    Most studies in the economics discourse argue that the impact of self-employment on job satisfaction is mediated by greater procedural freedom and autonomy. Values and personality traits are considered less likely to explain the utility difference between self-employed and salaried workers. Psychology scholars suggest that entrepreneurial satisfaction also depends, at least in part, on specific values and personality traits.

    The main objective of this report is to present a brief overview of the radiation environment that can be expected in areas where electronics is installed in the LHC. This covers particle energy spectra in addition to nominal integrated values of the High Energy Hadron (HEH) fluence, relevant for Single Event Effects (SEEs), Total Ionizing Dose (TID), and the 1 MeV neutron equivalent, relevant for displacement damage. The risk of thermal neutrons is considered by introducing the risk factor Rth. This report is presented as part of the R2E project and should create a foundation from which appropriate irradiation test criteria can be evaluated and determined.

  2. Life beyond MSE and R2 — improving validation of predictive models with observations

    Papritz, Andreas; Nussbaum, Madlene

    2017-04-01

    Machine learning and statistical predictive methods are evaluated by the closeness of predictions to observations of a test dataset. Common criteria for rating predictive methods are bias and mean square error (MSE), characterizing systematic and random prediction errors. Many studies also report R2-values, but their meaning is not always clear (correlation between observations and predictions or MSE skill score; Wilks, 2011). The same criteria are also used for choosing tuning parameters of predictive procedures by cross-validation and bagging (e.g. Hastie et al., 2009). For evident reasons, atmospheric sciences have developed a rich box of tools for forecast verification. Specific criteria have been proposed for evaluating deterministic and probabilistic predictions of binary, multinomial, ordinal and continuous responses (see reviews by Wilks, 2011, Jollie and Stephenson, 2012 and Gneiting et al., 2007). It appears that these techniques are not very well-known in the geosciences community interested in machine learning. In our presentation we review techniques that offer more insight into proximity of data and predictions than bias, MSE and R2 alone. We mention here only examples: (i) Graphing observations vs. predictions is usually more appropriate than the reverse (Piñeiro et al., 2008). (ii) The decomposition of the Brier score score (= MSE for probabilistic predictions of binary yes/no data) into reliability and resolution reveals (conditional) bias and capability of discriminating yes/no observations by the predictions. We illustrate the approaches by applications from digital soil mapping studies. Gneiting, T., Balabdaoui, F., and Raftery, A. E. (2007). Probabilistic forecasts, calibration and sharpness.

    Adolescence is a developmental phase associated with significant somatic and psychosocial changes. So far there are few studies on developmental aspects of life satisfaction. This cross-sectional study examines the effects of age and gender on adolescent's life satisfaction. 1,274 German adolescents (aged 11-16 years) participated in a school-based survey study. They completed the adolescent version of the Questions on Life Satisfaction (FLZ(M) - Fragen zur Lebenszufriedenheit), a multidimensional instrument measuring the subjective importance and satisfaction with eight domains of general and eight domains of health-related life satisfaction. Effects of gender and age were analysed using ANOVAs. Girls reported significantly lower general (F = 5.0; p = .025) and health-related life satisfaction (F = 25.3; p life domains, there was a significant decrease in general (F = 14.8; p life satisfaction (F = 8.0; p Satisfaction with friends remained on a high level, whereas satisfaction with family relations decreased. Only satisfaction with partnership/sexuality increased slightly, however this effect cannot compensate the general loss of satisfaction. Decreasing life satisfaction has to be considered as a developmental phenomenon. Associations with the increasing prevalence of depression and suicidal ideation during adolescence are discussed. Life satisfaction should be considered a relevant aspect of adolescent's well-being and functioning.

    Brain iron deposition has been proposed to play an important role in the pathophysiology of Alzheimer disease (AD). The aim of this study was to investigate the correlation of brain iron accumulation with the severity of cognitive impairment in patients with AD by using quantitative MR relaxation rate R2' measurements. Fifteen patients with AD, 15 age- and sex-matched healthy controls, and 30 healthy volunteers underwent 1.5T MR multi-echo T2 mapping and T2* mapping for the measurement of transverse relaxation rate R2' (R2'=R2*-R2). We statistically analyzed the R2' and iron concentrations of bilateral hippocampus (HP), parietal cortex (PC), frontal white matter (FWM), putamen (PU), caudate nucleus (CN), thalamus (TH), red nucleus (RN), substantia nigra (SN), and dentate nucleus (DN) of the cerebellum for the correlation with the severity of dementia. Two-tailed t-test, Student-Newman-Keuls test (ANOVA) and linear correlation test were used for statistical analysis. In 30 healthy volunteers, the R2' values of bilateral SN, RN, PU, CN, globus pallidus (GP), TH, and FWM were measured. The correlation with the postmortem iron concentration in normal adults was analyzed in order to establish a formula on the relationship between regional R2' and brain iron concentration. The iron concentration of regions of interest (ROI) in AD patients and controls was calculated by this formula and its correlation with the severity of AD was analyzed. Regional R2' was positively correlated with regional brain iron concentration in normal adults (r=0.977, PIron concentrations in bilateral HP, PC, PU, CN, and DN of patients with AD were significantly higher than those of the controls (Piron concentrations, especially in parietal cortex and hippocampus at the early stage of AD, were positively correlated with the severity of patients' cognitive impairment (Piron concentrations were, the more severe the cognitive impairment was.

    Background Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an arrhythmogenic disease for which electrophysiological studies (EPS) have shown to be of limited value. Objective We present a CPVT family in which marked post-pacing repolarization abnormalities during EPS were the only consistent phenotypic manifestation of RyR2 mutation carriers. Methods The study was prompted by the observation of transient marked QT prolongation preceding initiation of ventricular fibrillation during atrial fibrillation in a boy with a family history of sudden cardiac death (SCD). Family members underwent exercise and pharmacologic ECG testing with epinephrine, adenosine and flecainide. Non-invasive clinical tests were normal in 10 patients evaluated, except for both epinephrine and exercise-induced ventricular arrhythmias in 1. EPS included bursts of ventricular pacing and programmed ventricular extrastimulation reproducing short-long sequences. Genetic screening involved direct sequencing of genes involved in LQTS as well as RyR2. Results Six patients demonstrated a marked increase in QT interval only in the first beat after cessation of ventricular pacing and/or extrastimulation. All 6 patients were found to have a heterozygous missense mutation (M4109R) in RyR2. Two of them, presenting with aborted SCD also had a second missense mutation (I406T- RyR2). Four family members without RyR2 mutations did not display prominent post-pacing QT changes. Conclusions M4109R- RyR2 is associated with a high incidence of SCD. The contribution of I406T to the clinical phenotype is unclear. In contrast to exercise testing, marked post-pacing repolarization changes in a single beat accurately predicted carriers of M4109R- RyR2 in this family. PMID:21699856

    The RNA structure of the 3′ untranslated region (UTR) of the R2 retrotransposable element is recognized by the R2-encoded reverse transcriptase in a reaction called target primed reverse transcription (TPRT). To provide insight into structure–function relationships important for TPRT, we have created alignments that reveal the secondary structure for 22 Drosophila and five silkmoth 3′ UTR R2 sequences. In addition, free energy minimization has been used to predict the secondary structure for the 3′ UTR R2 RNA of Forficula auricularia. The predicted structures for Bombyx mori and F. auricularia are consistent with chemical modification data obtained with β-ethoxy-α-ketobutyraldehyde (kethoxal), dimethyl sulfate, and 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-p-toluene sulfonate. The structures appear to have common helices that are likely important for function. PMID:15146081

    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 breaks with the tradition of stovepipe portals built around complex search interfaces tightly bound to backend databases. Instead, we have adopted a Linked Data approach to publish our catalog content, based on the W3C Resource Description Framework (RDF) and Uniform Resource Identifiers (URIs). Our data model is published as a collection of W3C Simple Knowledge Organization System (SKOS) concepts, mapped to partner vocabularies such as those developed by the Global Change Master Directory (GCMD) and the pan-European SeaDataNet partnership, and our catalog content is published as collections of RDF resources with globally unique and persistent identifiers. The combination of exposing our data model, mapping local terms to community-wide vocabularies, and using reliable identifiers improves interoperability and reduces ambiguity. 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.

    2011-01-01

    Full Text Available Abstract 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. R2R software is available at http://breaker.research.yale.edu/R2R and as an Additional file.

    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.

    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.

    Despite considerable interest in the study of job satisfaction and dissatisfaction, our understanding of these phenomena has not increased substantially in the past 30 years. It is argued that a major reason for this lack of progress is the implicit conception of casuality accepted by most psychologists. It is called the policy of "correlation…

    Companies that embrace client orientation are preoccupied by measuring the level of satisfaction of those who consume their products or utilizes their products. That is why, customer satisfaction has to be transposed in measurable parameters that can be understood and influenced. Nevertheless, measuring customer satisfaction involves a lot of problems.

    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.

    In the heart, electrical stimulation of cardiac myocytes increases the open probability of sarcolemmal voltage-sensitive Ca2+ channels and flux of Ca2+ into the cells. This increases Ca2+ binding to ligand-gated channels known as ryanodine receptors (RyR2). Their openings cause cell-wide release of Ca2+, which in turn causes muscle contraction and the generation of the mechanical force required to pump blood. In resting myocytes, RyR2s can also open spontaneously giving rise to spatially-confined Ca2+ release events known as "sparks." RyR2s are organized in a lattice to form clusters in the junctional sarcoplasmic reticulum membrane. Our recent work has shown that the spatial arrangement of RyR2s within clusters strongly influences the frequency of Ca2+ sparks. We showed that the probability of a Ca2+ spark occurring when a single RyR2 in the cluster opens spontaneously can be predicted from the precise spatial arrangements of the RyR2s. Thus, "function" follows from "structure." This probability is related to the maximum eigenvalue (λ1) of the adjacency matrix of the RyR2 cluster lattice. In this work, we develop a theoretical framework for understanding this relationship. We present a stochastic contact network model of the Ca2+ spark initiation process. We show that λ1 determines a stability threshold for the formation of Ca2+ sparks in terms of the RyR2 gating transition rates. We recapitulate these results by applying the model to realistic RyR2 cluster structures informed by super-resolution stimulated emission depletion (STED) microscopy. Eigendecomposition of the linearized mean-field contact network model reveals functional subdomains within RyR2 clusters with distinct sensitivities to Ca2+. This work provides novel perspectives on the cardiac Ca2+ release process and a general method for inferring the functional properties of transmembrane receptor clusters from their structure.

    Imaging report turnaround time (RTAT) is an important measure of radiology performance and has become the leading priority in customer satisfaction surveys conducted among nonradiologists, who may not be familiar with the imaging workflow. Our aim was to assess physicians' expected RTAT for commonly ordered studies and determine if satisfaction correlates with met expectations. Retrospective review of inpatient imaging was conducted at a single academic institution, and RTAT for 18,414 studies was calculated. Examinations were grouped by study type, priority, and time of day. A cross-sectional survey instrument was completed by 48 internal medicine and surgery resident physicians with questions regarding RTAT and their level of satisfaction with various examinations. Actual RTAT ranged from 1.6 to 26.0 hours, with chest radiographs and computed tomographies generally faster than magnetic resonance images and ultrasounds. Urgent (STAT) examinations and those ordered during business hours have shorter RTAT. The time for image interpretation largely contributed to the RTAT because of the lack of night-time radiology coverage. Referring physician expectations were consistently shorter than actual RTAT, ranging from 30 minutes to 24 hours. Overall satisfaction scores were inversely correlated with RTAT, with a strong correlation to the time from study order to imaging (r(2) = 0.63) and a weak correlation to the image interpretation time (r(2) = 0.17). Satisfaction scores did not correlate with whether the actual RTAT met expectations (r(2) = 0.06). Referring physician satisfaction is likely multifactorial. Although RTAT has been reported as a priority, shortening turnaround time alone may not directly improve clinician satisfaction. Copyright © 2015 AUR. Published by Elsevier Inc. All rights reserved.

    While the importance of tourist satisfaction has been recognized by academic researchers for at least four decades, adequate tourist satisfaction models have not been developed or validated. This study presents a tourist satisfaction model for a destination and explores the antecedents (tourist expectations, destination image, perceived quality, and perceived value) and the consequences (tourist complaints and tourist loyalty) of tourist satisfaction using Guilin for the case study. Structural equation modeling results support the tourist satisfaction model of tourist expectations, destination image, perceived quality, and per-ceived value as four key antecedents of tourist satisfaction, with tourist satisfaction having a negative effect on tourist complaints and a positive effect on tourist loyalty. Managerial implications are drawn from the study findings and suggestions are given for future work.

    本文考察感知价值、满意度对继续使用意向的作用机理。基于以往研究,本文首先提出了3G用户继续使用意向概念模型与假设,然后对假设进行了实证检验。研究结果表明感知价值和满意度对继续使用意向具有重要作用。满意度是继续使用意向最强的预测因子。感知有用性和感知使用成本不仅直接作用于继续使用意向,也通过满意度间接作用于继续使用意向。感知易用性和感知形象提升直接作用于继续使用意向,满意度不起中介作用。%The revenue of telecommunication operators from 3G services is largely determined by users' intention to continue using 3G services.To enhance the continuance intention of 3G users,we need to know determinants of users' continuance intention.Synthesizing theories from the theory of reasoned action(TRA),the technology acceptance model(TAM) and the expectation-confirmation theory (ECT),we built and tested a theoretical model of determinants of users' continuance intention.The perceived values were composed of perceived usefulness,perceived ease of use,perceived image and perceived cost.We hypothesized that four dimensions of perceived values not only had direct effects but also had indirect direct effect via satisfaction on users' continuance intention. The data was collected from 3G users through questionnaires in China.The measurement scales were developed from relevant scales in extant literature to ensure content validity.The measurement scales were pretested and refined to ensure high convergent validity and discriminant validity before large scale surveys.We used structural equation modeling to analyze the data and test the hypotheses. The results suggest that users' continuance intention is determined by satisfaction and perceived values.Perceived usefulness and perceived cost has not only direct but also indirect effects via satisfaction on continuance intention.Perceived ease of use and perceived

    The purpose of this study was to assess satisfaction with specific aspects of care for acute neck pain and explore the relationship between satisfaction with care, neck pain, and global satisfaction. This study was a secondary analysis of patient satisfaction from a randomized trial of spinal manipulation therapy (SMT) delivered by doctors of chiropractic, home exercise and advice (HEA) delivered by exercise therapists, and medication (MED) prescribed by a medical doctors for acute/subacute neck pain. Differences in satisfaction with specific aspects of care were analyzed using a linear mixed model. The relationship between specific aspects of care and (1) change in neck pain (primary outcome of the randomized trial) and (2) global satisfaction were assessed using Pearson's correlation and multiple linear regression. Individuals receiving SMT or HEA were more satisfied with the information and general care received than MED group participants. Spinal manipulation therapy and HEA groups reported similar satisfaction with information provided during treatment; however, the SMT group was more satisfied with general care. Satisfaction with general care (r = -0.75 to -0.77; R(2) = 0.55-0.56) had a stronger relationship with global satisfaction compared with satisfaction with information provided (r = -0.65 to 0.67; R(2) = 0.39-0.46). The relationship between satisfaction with care and neck pain was weak (r = 0.17-0.38; R(2) = 0.08-0.21). Individuals with acute/subacute neck pain were more satisfied with specific aspects of care received during spinal manipulation therapy or home exercise interventions compared to receiving medication. The relationship between neck pain and satisfaction with care was weak. Copyright © 2014 National University of Health Sciences. Published by Elsevier Inc. All rights reserved.

  15. RyR2 modulates a Ca2+-activated K+ current in mouse cardiac myocytes.

    Full Text Available In cardiomyocytes, Ca2+ entry through voltage-dependent Ca2+ channels (VDCCs binds to and activates RyR2 channels, resulting in subsequent Ca2+ release from the sarcoplasmic reticulum (SR and cardiac contraction. Previous research has documented the molecular coupling of small-conductance Ca2+-activated K+ channels (SK channels to VDCCs in mouse cardiac muscle. Little is known regarding the role of RyRs-sensitive Ca2+ release in the SK channels in cardiac muscle. In this study, using whole-cell patch clamp techniques, we observed that a Ca2+-activated K+ current (IK,Ca recorded from isolated adult C57B/L mouse atrial myocytes was significantly decreased by ryanodine, an inhibitor of ryanodine receptor type 2 (RyR2, or by the co-application of ryanodine and thapsigargin, an inhibitor of the sarcoplasmic reticulum calcium ATPase (SERCA (p<0.05, p<0.01, respectively. The activation of RyR2 by caffeine increased the IK,Ca in the cardiac cells (p<0.05, p<0.01, respectively. We further analyzed the effect of RyR2 knockdown on IK,Ca and Ca2+ in isolated adult mouse cardiomyocytes using a whole-cell patch clamp technique and confocal imaging. RyR2 knockdown in mouse atrial cells transduced with lentivirus-mediated small hairpin interference RNA (shRNA exhibited a significant decrease in IK,Ca (p<0.05 and [Ca2+]i fluorescence intensity (p<0.01. An immunoprecipitated complex of SK2 and RyR2 was identified in native cardiac tissue by co-immunoprecipitation assays. Our findings indicate that RyR2-mediated Ca2+ release is responsible for the activation and modulation of SK channels in cardiac myocytes.

    We aimed to evaluate the feasibility of quantification of liver, pancreas, spleen, vertebral bone marrow, and renal cortex R2* and magnetic resonance imaging-proton density fat fraction (MRI-PDFF) and to evaluate the correlations among them in patients with transfusion-related iron overload. A total of 9 patients (5 boys, 4 girls) who were referred to our clinic with suspicion of hepatic iron overload were included in this study. All patients underwent T1-independent volumetric multi-echo gradient-echo imaging with T2* correction and spectral fat modeling. MRI examinations were performed on a 1.5 T MRI system. All patients had hepatic iron overload. Severe hepatic iron overload was recorded in 5/9 patients (56%), and when we evaluated the PDFF maps of these patients, we observed an extensive patchy artifact in the liver in 4 of 5 patients (R2* greater than 671 Hz). When we performed MRI-PDFF measurements despite these artifacts, we observed artifactual high MRI-PDFF values. There was a close correlation between average pancreas R2* and average pancreas MRI-PDFF (p=0.003, r=0.860). There was a significant correlation between liver R2* and average pancreas R2* (p=0.021, r=0.747), liver R2* and renal cortex R2* (p=0.020, r=0.750), and average pancreas R2* and renal cortex R2* (p=0.003, r=0.858). There was a significant negative correlation between vertebral bone marrow R2* and age (p=0.018, r=-0.759). High iron content of the liver, especially with a T2* value shorter than the first echo time can spoil the efficacy of PDFF calculation. Fat deposition in the pancreas is accompanied by pancreatic iron overload. There is a significant correlation between hepatic siderosis and pancreatic siderosis. Renal cortical and pancreatic siderosis are correlated, too.

    Objectives: Although many studies were focused on the assessment of patients' satisfaction, few studies have specifically addressed this issue for knee osteoartritis. Global rating of change (GRC) scales are very commonly used in clinical research, particularly in the musculoskeletal area. The purpose of this study was to evaluate the patients’ satisfaction of the Mulligan’s Mobilization with Movement (MWM) techniques, Passive Mobilization (PM) techniques and physical therapy modalities (PTM) (superficial heat or cold, Transcutaneous Electrical Nerve Stimulation (TENS) and therapeutic ultrasound) in subjects with osteoarthritis of the knee. Methods: Thirty subjects with bilateral osteoarthritis of the knee were randomly assigned to the MWM group (n=21) or the PM group (n=21) or PTM group (n=22). The duration of treatment was a maximum of 5 weeks (12 sessions) in all groups. The subjects’ satisfaction were assessed before and after treatment by the GRC scales. One-way analysis of variance was used to compare the groups. When significance was observed, pairwise post hoc tests were performed using Tukey’s test. Results: Mean age and body mass index (BMI) of our study group were 54±7 years and 31±5 kg/m²,respectively in the MWM group, 56±6 years and 31±4 kg/m²,respectively in the PM group and 57±6 years and 32±5 kg/m²,respectively in the PTM group There were no significant differences between the groups with respect to age, BMI and GRC before treatment (p>0.05). Patients satisfaction of the three groups after treatment were significantly different (F=6.732 p=0.002). Pairwise comparisons of the treatment groups revealed a significant difference in the patients’ satisfaction between MWM and PTM (p=0.007), and between PM and PTM (p=0.007); there was no significant difference between MWM and PM (p>0.05). Conclusion: Manual therapy seemed to be superior to physical therapy modalities for the patients’ satisfaction. Therefore, we suggest that

    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.

    To assess whether development of health services in Norway has been well balanced in terms of satisfaction; time series variation has been compared for population satisfaction with health services and physician job satisfaction. Data were retrieved from the following sources and years: the reference panel of The Research Institute of the Norwegian Medical Association on physician job satisfaction in the years 1994, 2000, 2002 and 2006; the municipal surveys of TNS Gallup on population satisfaction with health care (primary) in the years 1995 - 2000, 2003 and 2005 and in 1999, 2000 and 2003 for satisfaction with hospitals, and from the Norwegian part of the International Social Survey Program (ISSP) on population willingness to allocate resources to public health care (in 1990 and 2006). Time series of physician satisfaction were computed from changes in satisfaction between consecutive surveys. Time series of population satisfaction were computed from annual regression-adjusted means that control for the association between satisfaction and observable personal characteristics. On a scale from 10 to 70, hospital doctors' job satisfaction increased from 50.2 in 1994 to 52.3 in 2006. General practitioners' job satisfaction increased from 52.3 to 55.5 in the same period. From 1995 to 2005, consumer satisfaction with primary care increased from 4.43 to 4.54 and with hospital services from 4.23 to 4.47 (on a scale from 1 to 6). The proportion of the population who believes more public resources should be spent on health care increased from 82.7 % in 1990 to 85.2 % in 2006. The development in the health care sector seems to be balanced in the sense that views of the population and health personnel have followed parallel trajectories. A large and increasing share of the population is willing to allocate more resources to health care.

    Rapid saltatory nerve conduction is facilitated by myelin structure, which is produced by Schwann cells (SC) in the peripheral nervous system (PNS). Proper development and degeneration/regeneration after injury requires regulated phenotypic changes of SC. We have previously shown that glutamate can induce SC proliferation in culture. Here we show that glutamate signals through metabotropic glutamate receptor 2 (mGluR2) to induce Erk phosphorylation in SC. mGluR2-elicited Erk phosphorylation requires ErbB2/3 receptor tyrosine kinase phosphorylation to limit the signaling cascade that promotes phosphorylation of Erk, but not Akt. We found that Gβγ and Src are involved in subcellular signaling downstream of mGluR2. We also found that glutamate can transform myelinating SC to proliferating SC, while inhibition of mGluR2 signaling can inhibit demyelination of injured nerves in vivo. These data suggest pathophysiological significance of mGluR2 signaling in PNS and its possible therapeutic importance to combat demyelinating disorders including Charcot-Marie-Tooth disease.

    In order to construct objective relatively mapping relationship model between customer requirements and product technical characteristics, a novel approach based on customer satisfactions information digging from case products and satisfaction information of expert technical characteristics was put forward in this paper. Technical characteristics evaluation values were expressed by rough number, and technical characteristics target sequence was determined on the basis of efficiency, cost type and middle type in this method. Use each calculated satisfactions of customers and technical characteristics as input and output elements to construct BP network model. And we use MATLAB software to simulate this BP network model based on the case of electric bicycles.

    2013-01-01

    The purpose of this study is to explain the effect of participation in productive activities on life satisfaction and its implications for social evaluation of productive aging. This study uses data collected from 1,250 elderly women living in urban areas. The regression model was used to examine the influence of elderly women's participation in productive activities on their life satisfaction. Elderly women who participate in volunteer work, learning, and social group activities commonly recognized their activities as meaningful, feeling like worthwhile members of society, and evaluated such activities as very positive. In contrast, elderly women who participated in household chores and family care activities expressed a negative life satisfaction. The difference in life satisfaction regarding productive activities stems not only from the physical and environmental differences but also from the gap between the official social value underpinned by the recognition of surrounding people, their support, and the value of productive activities.

    Full Text Available Abstract Over-activation of AMPARs (α−amino-3-hydroxy-5-methylisoxazole-4-propionic acid subtype glutamate receptors is implicated in excitotoxic neuronal death associated with acute brain insults, such as ischemic stroke. However, the specific molecular mechanism by which AMPARs, especially the calcium-impermeable AMPARs, induce neuronal death remains poorly understood. Here we report the identification of a previously unrecognized molecular pathway involving a direct protein-protein interaction that underlies GluR2-containing AMPAR-mediated excitotoxicity. Agonist stimulation of AMPARs promotes GluR2/GAPDH (glyceraldehyde-3-phosphate dehydrogenase complex formation and subsequent internalization. Disruption of GluR2/GAPDH interaction by administration of an interfering peptide prevents AMPAR-mediated excitotoxicity and protects against damage induced by oxygen-glucose deprivation (OGD, an in vitro model of brain ischemia.

    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.

  9. Design and implementation of adaptive PI control schemes for web tension control in roll-to-roll (R2R) manufacturing.

    Science.gov (United States)

    Raul, Pramod R; Pagilla, Prabhakar R

    2015-05-01

    In this paper, two adaptive Proportional-Integral (PI) control schemes are designed and discussed for control of web tension in Roll-to-Roll (R2R) manufacturing systems. R2R systems are used to transport continuous materials (called webs) on rollers from the unwind roll to the rewind roll. Maintaining web tension at the desired value is critical to many R2R processes such as printing, coating, lamination, etc. Existing fixed gain PI tension control schemes currently used in industrial practice require extensive tuning and do not provide the desired performance for changing operating conditions and material properties. The first adaptive PI scheme utilizes the model reference approach where the controller gains are estimated based on matching of the actual closed-loop tension control systems with an appropriately chosen reference model. The second adaptive PI scheme utilizes the indirect adaptive control approach together with relay feedback technique to automatically initialize the adaptive PI gains. These adaptive tension control schemes can be implemented on any R2R manufacturing system. The key features of the two adaptive schemes is that their designs are simple for practicing engineers, easy to implement in real-time, and automate the tuning process. Extensive experiments are conducted on a large experimental R2R machine which mimics many features of an industrial R2R machine. These experiments include trials with two different polymer webs and a variety of operating conditions. Implementation guidelines are provided for both adaptive schemes. Experimental results comparing the two adaptive schemes and a fixed gain PI tension control scheme used in industrial practice are provided and discussed.

    2010-01-01

    Objectives: To set up and validate a patient satisfaction questionnaire based on Iowa Satisfaction in Anesthesia Scale (ISAS) for evaluating the degree of patient satisfaction in anesthesia. Materials and Methods: We established and validated a survey questionnaire of 13 questions measuring the following dimensions adequacy of patient information; participation in decision making, nurse patient relation, accessibility of communication with the anesthesiologist, patient fear and anxiety and the post anesthesia care management. The process passed through three steps: instrument validation, survey conduction and data analysis. Cronbach's alpha was used to measure the reliability and standard psychometric techniques were used to measure instrument validity. Results: Our modified instrument shows good reliability which is obvious with a Cronbach's alpha value of 0.72 and all the perspectives of validity (face, content and construct). Also, 173 (21.54%) patients achieved an overall satisfaction score of less than 85% female patients are were less satisfied than male patients. Educated patients were less satisfied, and those belonging to ASA group I and II were significantly less satisfied. Dimensions pinpointed are related to information and decision making, adverse events in recovery room, fear and anxiety contributed to patient dissatisfaction. Conclusion: The instrument used for the evaluation of patient satisfaction in anesthesia is a valid tool for the Arabic speaking patients. There is room for improvement in the anesthesia care, mainly in the dimension of information, decision making and postoperative anesthesia care. PMID:25885236

    2010-12-01

    With its global capability and diverse array of sensors, the academic research fleet is an integral component of ocean exploration. The Rolling Deck to Repository (R2R) Program provides a central shore-side gateway for underway data from the U.S. academic research fleet. In addition to ensuring preservation and documentation of routine underway data, R2R is also developing automated quality assessment (QA) tools for a variety of underway data types. Routine post-cruise QA will enable prompt feedback to shipboard operators and to provide the science community with sufficient background information for data analysis. Based on community feedback, R2R will perform data reduction to generate enhanced data products for select data types including gravity and magnetics. In the development of these tools, R2R seeks input from the scientific community, engaging specialists for each data type and requesting feedback from operators and scientists to deliver the most relevant and useful metadata. Development of data acquisition best practices that are being assembled within the community for some data types will also be important components of R2R QA development. Protocols for gravity and magnetics QA will include the development of guidelines for minimal and optimal metadata for each data type that will enable data reduction and optimize data re-use. Metadata including instrument specifications, navigational offsets, and calibration information will be important inputs for both data reduction and QA. Data reduction will include merging these geophysical data types with high-quality R2R-generated navigation data products, cleaning the data and applying instrument corrections. Automated routines that are being developed will then be used to assess data quality, ultimately producing a Quality Assessment Certificate (QAC) that will provide the science community with quality information in an easily accessible and understandable format. We present progress to date and invite

    2016-01-01

    Full Text Available The quality of built environment usually influences the walkability of a city. This is because each pedestrian walk differently on different type of facilities or built environment provided to them. This paper aims to investigate whether gender differences influences the pedestrian perception and satisfaction level at three sidewalks located within the Kuala Lumpur City Center by means of questionnaire survey. A total of 317 pedestrians were involved in the questionnaire survey at the three different sidewalk locations. The result shows significant differences in mean satisfaction value between male and female pedestrians. Female pedestrian give lower satisfaction value for overall travel experience at Jalan Tuanku Abdul Rahman but higher satisfaction value at Petaling Street and Bukit Bintang compared to male pedestrian. Overall, the satisfaction level was rated between acceptable to satisfactory regardless of gender differences. Improvements should be made for the safety parameter because both male and female pedestrian gives lowest satisfaction level in that area.

    NSF-supported oceanographic research expeditions support diverse scientific investigations across all disciplines of ocean sciences, targeting important questions ranging from the impacts of global change on ocean chemistry and ecosystems, to the structure and dynamics of ocean circulation and the nature of volcanic and earthquake processes at the global plate boundaries. Research vessels coordinated by the University-National Oceanographic Laboratory System (UNOLS) are the primary oceanographic research platforms, and operate as essential mobile observing platforms for ocean science. Ships ranging from “global” to “local” class are capable of operating throughout the deep oceans and within coastal and inland waterways. Each vessel is equipped with a suite of sensors, including geophysical, water column, and meteorological sensors, that are available for continuous operation during each expedition. The “underway” datasets obtained from these sensors provide characterization of basic environmental conditions for the oceans and are of high value for later reuse for building global syntheses, climatologies, and historical time series of ocean properties. The recently funded Rolling Deck to Repository (R2R) Project aims to develop a comprehensive plan for fleet-wide data management to ensure preservation and accessibility of our national oceanographic research data resources. The R2R Portal (www.rvdata.us) is being developed as a central shore-side data gateway through which underway data from oceanographic expeditions can be routinely cataloged and securely transmitted to the national long-term digital data archives including the National Geophysical Data Center (NGDC) and the National Oceanographic Data Center (NODC). R2R will provide essential data documentation services for every expedition along with new tools to improve documentation of the wide array of shipboard data collection activities typical of modern expeditions. Protocols will be developed

    Fallarino, Lorenzo; Binek, Christian; Berger, Andreas

    2015-06-01

    The magnetoelectric antiferromagnet α -C r2O3 (chromia) is known to possess a roughness insensitive net equilibrium magnetization at the (0001) surface, called boundary magnetization (BM), which is coupled to the bulk antiferromagnetic order parameter. In order to verify whether this symmetry sensitive BM persists in alloys, we investigate the impact of diamagnetic dilution on chromia thin films alloyed with the isostructural α -A l2O3 (alumina). Single-crystalline C r2 -xA lxO3 thin films with (0001) surface orientation and varying stoichiometry have been grown by sputter codeposition in the concentration range between x =0 and x =0.6 . For these samples, we find the corundum crystal structure, the antiferromagnetic ordering, and the boundary magnetization to be preserved. We also find that the critical temperature TN can be tuned by alloying with α -A l2O3 , using the BM as a probe to study the magnetic phase transition. Furthermore, we were able to evaluate the critical exponent and the absolute BM values for different samples. Both properties corroborate that the observed magnetic signals originate from the BM rather than the bulk of the samples.

    Arko, Robert; Carbotte, Suzanne; Chandler, Cynthia; Smith, Shawn; Stocks, Karen

    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

    2009-12-01

    The Rolling Deck to Repository (R2R) project was recently launched with the ambitious goal of documenting “routine underway data” from the US academic research fleet and delivering those data to established national archives. Data distributions will be submitted by 18 operating institutions for 30 vessels, from hundreds of cruises per year. R2R will be responsible for digital data collected with instruments that are part of the ship’s permanent equipment and are routinely operated and recorded by the ship’s technicians. Examples include navigation, multibeam, subbottom, gravimeter, magnetics, ADCP, CTD, meteorology, etc. It is anticipated that most underway data will be promptly and publicly released. However R2R will have the ability to securely embargo any specific datasets identified in advance by the chief scientist, for a proprietary hold period of up to two years as mandated by the NSF 04-004 Division of Ocean Sciences Data and Sample Policy. It is important to note that there are data types that R2R will not address. For example, the chief scientist will continue to be responsible for the documentation and archiving of data from specific instruments brought on board by the scientific party, not part of the ship’s standard equipment. Similarly, data collected with National Facility assets including the National Deep Submergence Facility (NDSF), Ocean Bottom Seismograph Instrument Pool (OBSIP) and the National Marine Seismic Facility (NMSF) will continue to be submitted to the appropriate archiving facility directly by those facilities, rather than through R2R. Soon after the shipboard data is received by R2R, the entire original distribution will be safely stored in a deep archive for long-term preservation, and a cataloging process will be undertaken to assemble data sets for delivery to National Data Centers, as described more fully in the invited presentation by Robert Arko, “Rolling Deck to Repository: Technical Design - Experiences and

    Consider the existence of nontrivial solutions of homogeneous Dirichlet problem for a nonlinear elliptic equation with the critical potential in R2. By establishing a weighted inequality with the best constant, determine the critical potential in R2, and study the eigenvalues of Laplace equation with the critical potential. By the Pohozaev identity of a solution with a singular point and the Cauchy-Kovalevskaya theorem, obtain the nonexistence result of solutions with singular points to the nonlinear elliptic equation. Moreover, for the same problem, the existence results of multiple solutions are proved by the mountain pass theorem.

    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.

    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.

    We discuss explicit examples of BPS solutions in four-dimensional N=2 supergravity with R^2-interactions. We demonstrate how to construct solutions by iteration. Generically, the presence of higher-curvature interactions leads to non-static spacetime line elements. We comment on the existence of horizons for multi-centered solutions.

  1. Occurrence of exact $R^2$ inflation in non-local UV-complete gravity

    2016-01-01

    The $R+R^2$, shortly named "$R^2$" ("Starobinsky") inflationary model, represents a fully consistent example of a one-parameter inflationary scenario. This model has a "graceful exit" from inflation and provides a mechanism for subsequent creation and final thermalization of the standard matter. Moreover, it produces a very good fit of the observed spectrum of primordial perturbations. In the present paper we show explicitly that the $R^2$ inflationary spacetime is an exact solution of a range of weakly non-local (quasi-polynomial) gravitational theories, which provide an ultraviolet completion of the $R^2$ theory. These theories are ghost-free, super-renormalizable or finite at quantum level, and perturbatively unitary. Their spectrum consists of the graviton and the scalaron that is responsible for driving the inflation. Notably, any further extension of the spectrum leads to propagating ghost degrees of freedom. We are aimed at presenting a detailed construction of such theories in the so called Weyl basis...

    Context. Monoceros R2 (Mon R2), at a distance of 830 pc, is the only ultra-compact H ii region (UC H ii) where its associated photon-dominated region (PDR) can be resolved with the Herschel Space Observatory. Aims. Our aim is to investigate observationally the kinematical patterns in the interface regions (i.e., the transition from atomic to molecular gas) associated with Mon R2. Methods. We used the HIFI instrument onboard Herschel to observe the line profiles of the reactive ions CH+, OH+ and H2O+ toward different positions in Mon R2. We derive the column density of these molecules and compare them with gas-phase chemistry models. Results. The reactive ion CH+ is detected both in emission (at central and red-shifted velocities) and in absorption (at blue-shifted velocities). OH+ is detected in absorption at both blue- and red-shifted velocities, with similar column densities. H2O+ is not detected at any of the positions, down to a rms of 40 mK toward the molecular peak. At this position, we find that the OH...

    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

    The Two-Factor Theory of job satisfaction distinguishes between intrinsic-motivation (i.e. recognition, responsibility) and extrinsic-hygiene (i.e. job security, salary, working conditions) factors. The presence of intrinsic-motivation facilitates higher satisfaction and performance, whereas the absences of extrinsic factors help mitigate against dissatisfaction. The consideration of these factors and their impact on dentists' job satisfaction is essential for the recruitment and retention of dentists. The objective of the study is to assess the level of job satisfaction of German dentists and the factors that are associated with it. This cross-sectional study was based on a job satisfaction survey. Data were collected from 147 dentists working in 106 dental practices. Job satisfaction was measured with the 10-item Warr-Cook-Wall job satisfaction scale. Organizational characteristics were measured with two items. Linear regression analyses were performed in which each of the nine items of the job satisfaction scale (excluding overall satisfaction) were handled as dependent variables. A stepwise linear regression analysis was performed with overall job satisfaction as the dependent outcome variable, the nine items of job satisfaction and the two items of organizational characteristics controlled for age and gender as predictors. The response rate was 95.0%. Dentists were satisfied with 'freedom of working method' and mostly dissatisfied with their 'income'. Both variables are extrinsic factors. The regression analyses identified five items that were significantly associated with each item of the job satisfaction scale: 'age', 'mean weekly working time', 'period in the practice', 'number of dentist's assistant' and 'working atmosphere'. Within the stepwise linear regression analysis the intrinsic factor 'opportunity to use abilities' (β = 0.687) showed the highest score of explained variance (R(2) = 0.468) regarding overall job satisfaction. With respect to the Two

  12. 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.

    A Constraint Satisfaction Problem (CSP) consists of a set of variables, a domain of values for each variable and a set of constraints. The objective is to assign a value for each variable such that all constraints are satisfied. CSPs continue to receive increased attention because of both their high complexity and their omnipresence in academic, industrial and even real-life problems. This is why they are the subject of intense research in both artificial intelligence and operations research. This book introduces the classic CSP and details several extensions/improvements of both formalisms a

    Several Pt(IV) and Pt(II) complexes containing 1R,2R-cyclohexanediamine (1R,2R-dach) as a carrier ligand were synthesized. The cytotoxicities and the uptake of the platinum complexes by leukemia L1210 cells were compared in order to study the correlation between their structures and cytotoxicities. [Pt(II)Cl2(1R,2R-dach)], [(Pt(II)(oxalato)(1R,2R-dach)], and [Pt(II)(malonato)(1R,2R-dach)], which have excellent anticancer properties, exhibited very high cytotoxicities and were easily taken up by leukemia L1210 cells. [Pt(IV)Cl4(1R,2R-dach)], trans(Cl)-[Pt(IV)Cl2(oxalato)(1R,2R-dach)], and trans(Cl)-[Pt(IV)Cl2(malonato)(1R,2R-dach)] also had high cytotoxicities. After a short incubation time, the uptake of [Pt(II)Cl2(1R,2R-dach)], [Pt(II)(oxalato)(1R,2R-dach)], and [Pt(II)(malonato)(1R,2R-dach)] by leukemia L1210 cells were respectively very similar to those of [Pt(IV)Cl4(1R,2R-dach)], trans(Cl)-[Pt(IV)Cl2(oxalato)(1R,2R-dach)], and trans(Cl)-[Pt(IV)Cl2(malonato)(1R,2R-dach)]. In addition, trans(OH)-[Pt(IV)(OH)2Y2(1R,2R-dach)] (Y2: oxalato or malonato) did not exhibit cytotoxicity towards leukemia L1210 cells, whereas trans(Cl)-[Pt(IV)Cl2Y2(1R,2R-dach)] (Y2: oxalato or malonato) were highly cytotoxic. The accumulation of trans(OH)-[Pt(IV)(OH)2Y2(1R,2R-dach)] in leukemia L1210 cells was much lower than that of trans(Cl)-[Pt(IV)Cl2Y2(1R,2R-dach)]. Platinum(IV) complexes, in which leaving groups are replaced by hydroxide groups, have decreased cytotoxic activity, because the hydroxide groups of the platinum(IV) complex reduce the uptake of platinum by the cells. trans(OH),cis(Cl)-[Pt(IV)(OH)2Cl2(1R,2R-dach)], which has hydroxide and chloride groups, was easily incorporated into the cells and exhibited the high cytotoxic activity. This behavior indicates that the chloride group apparently overcomes the ameliorating effect of the hydroxide group.

    Organizational culture refers to the beliefs and values that have existed in an organization for a long time, and to the beliefs of the staff and the foreseen value of their work that will influence their attitudes and behavior. Administrators usually adjust their leadership behavior to accomplish the mission of the organization, and this could influence the employees' job satisfaction. It is therefore essential to understand the relationship between organizational culture, leadership behavior and job satisfaction of employees. A cross-sectional study was undertaken that focused on hospital nurses in Taiwan. Data was collected using a structured questionnaire; 300 questionnaires were distributed and 200 valid questionnaires were returned. To test the reliability of the data, they were analyzed by Cronbach's α and confirmatory factors. Correlation analysis was used on the relationships between organizational cultures, leadership behavior and job satisfaction. Organizational cultures were significantly (positively) correlated with leadership behavior and job satisfaction, and leadership behavior was significantly (positively) correlated with job satisfaction. The culture within an organization is very important, playing a large role in whether it is a happy and healthy environment in which to work. In communicating and promoting the organizational ethos to employees, their acknowledgement and acceptance of it can influence their work behavior and attitudes. When the interaction between the leadership and employees is good, the latter will make a greater contribution to team communication and collaboration, and will also be encouraged to accomplish the mission and objectives assigned by the organization, thereby enhancing job satisfaction.

    Research on doctor career satisfaction has often focused on factors such as income, specialty, gender, work hours, autonomy, patient load, lifestyle preferences, work environment, and insurance regulations. Other educational, personal and professional factors have not received sufficient empirical attention. This study was designed to test the following five hypotheses that doctors' career satisfaction is associated with: (i) Higher satisfaction with their undergraduate medical education; (ii) Greater academic and clinical competence; (iii) More involvement in teaching and research activities; (iv) Higher orientation toward lifelong learning; and (v) Increased professional accomplishments. A survey was mailed in 2006 to a national sample of 5349 doctors in the United States who graduated from Jefferson Medical College between 1975 and 2000; 3170 (59%) returned completed surveys. Based on responses to a career satisfaction question, doctors were classified into three groups: Highly satisfied (top third, n=1078); moderately satisfied (middle third, n=1031); and least satisfied (bottom third, n=1061). These groups were compared on a number of variables. All five research hypotheses were confirmed. Additionally, no significant association was observed between career satisfaction, age, years in practice, gender, or ethnicity; however, career satisfaction was associated with doctors' specialties. The findings suggest that factors such as satisfaction with medical education, medical school class rank, assessments of clinical competence, teaching, and research activities, orientation toward lifelong learning, and professional accomplishments should be considered for a more comprehensive understanding of doctors' career satisfaction. © Blackwell Publishing Ltd 2010.

    2011-05-01

    To examine the factors that impact career satisfaction for various surgical specialties. An acute shortage of surgeons is anticipated in the future. Career dissatisfaction can make this already difficult situation worse. It is important to understand and address factors that influence career satisfaction of surgeons to prolong tenure of existing surgeons and understand anticipated needs of future surgeons. The Center for Studying Health System Change 2008 Health Tracking Physician Survey data were used in this study. Regression analysis was done to examine the impact of various practice-related factors, compensation-related factors, practice location, extent of minority patient, and various demographics on career satisfaction of various surgical specialties (n = 762). Among practice related factors, although threat of malpractice had a significant negative impact on career satisfaction, ability to provide quality care to patients and time with patients had a significant positive impact on career satisfaction of surgical specialists. Among compensation related factors, income and financial incentives to expand services had a significant positive impact on career satisfaction. Among practice location factors, those who primarily worked in medical schools were significantly more satisfied with their careers than others. Among minority factors, those treating a large proportion of Hispanic patients were significantly less likely to be satisfied with their careers. Ability to provide quality care, time with patients, income, and financial incentives had a significant positive impact on career satisfaction. Similarly, threat of malpractice and high proportion of Hispanic patients had a negative impact on career satisfaction.

    Providing and maintaining customer satisfaction is one of the most important challenges facing business today. Although this is a relatively new concept, research into this area has grown since the early 1980s. One ongoing debate in consumer satisfaction circles is the extent to which it is a cognitive process or an emotional state. The two theories that best explain customer satisfaction are disconfirmation paradigm and expectancy-value concept. Disconfirmation theory postulates that cus...

  20. The Wide Distribution and Change of Target Specificity of R2 Non-LTR Retrotransposons in Animals

    Science.gov (United States)

    Seto, Yosuke; Fujiwara, Haruhiko

    2016-01-01

    Transposons, or transposable elements, are the major components of genomes in most eukaryotes. Some groups of transposons have developed target specificity that limits the integration sites to a specific nonessential sequence or a genomic region to avoid gene disruption caused by insertion into an essential gene. R2 is one of the most intensively investigated groups of sequence-specific non-LTR retrotransposons and is inserted at a specific site inside of 28S ribosomal RNA (rRNA) genes. R2 is known to be distributed among at least six animal phyla even though its occurrence is reported to be patchy. Here, in order to obtain a more detailed picture of the distribution of R2, we surveyed R2 using both in silico screening and degenerate PCR, particularly focusing on actinopterygian fish. We found two families of the R2C lineage from vertebrates, although it has previously only been found in platyhelminthes. We also revealed the apparent movement of insertion sites of a lineage of actinopterygian R2, which was likely concurrent with the acquisition of a 28S rRNA-derived sequence in their 3′ UTR. Outside of actinopterygian fish, we revealed the maintenance of a single R2 lineage in birds; the co-existence of four lineages of R2 in the leafcutter bee Megachile rotundata; the first examples of R2 in Ctenophora, Mollusca, and Hemichordata; and two families of R2 showing no target specificity. These findings indicate that R2 is relatively stable and universal, while differences in the distribution and maintenance of R2 lineages probably reflect characteristics of some combination of both R2 lineages and host organisms.

    to motivation and independent in their genesis, although there is interaction between them: the lack of satisfaction at work and job satisfaction. Both aspects are analyzed in this paper and their influence in the creation of economic value in business. In this scenario, it is fundamental that the firm identify and know the expectations of each one of its workers. This will allow to establish strategies to harmonize these expectations with the organizational objectives and the creation of economic value. This type of initiative tends to reduce the lack of satisfaction and to improve personal motivation.

  7. On the limit cycle for the 1/r^2 potential in momentum space

    Hammer, H W; Swingle, Brian G.

    2006-01-01

    The renormalization of the attractive 1/r^2 potential has recently been studied using a variety of regulators. In particular, it was shown that renormalization with a square well in position space allows multiple solutions for the depth of the square well, including, but not requiring a renormalization group limit cycle. Here, we consider the renormalization of the 1/r^2 potential in momentum space. We regulate the problem with a momentum cutoff and absorb the cutoff dependence using a momentum-independent counterterm potential. The strength of this counterterm is uniquely determined and runs on a limit cycle. We also calculate the bound state spectrum and scattering observables, emphasizing the manifestation of the limit cycle in these observables.

  8. R2 Correction and Its Implication of Present Cosmic Accelerating Behavior

    2004-01-01

    In this work we show an R + αR2 model of the universe in which certain quadratic correction is considered. Our results indicate that the R2 term can act as the present impetus of cosmic acceleration, but there may be a future collapsing universe with this component damped. This model can also tolerate a negative cosmological constant A,although there seems to be no need for a non-vanishing one. In our simplification, this curvature component has a stationary equation of state, which is similar to radiation. Unlike other dark energy models, this "missing" energy has a negative density. Some details and effects on cold dark matter and A-relevant model have been discussed in the frame of curvature-squared gravity theories.

    2016-01-01

    Models of geometric flows pertaining to $\\mathcal{R}^2$ scale invariant (super) gravity theories coupled to conformally invariant matter fields are investigated. Related to this work are supersymmetric scalar manifolds that are isomorphic to the K\\"{a}hlerian spaces $\\mathcal{M}_n=SU(1,1+k)/U(1)\\times SU(1+k)$ as generalizations of the non-supersymmetric analogs with $SO(1,1+k)/SO(1+k)$ manifolds. For curved superspaces with geometric evolution of physical objects, a complete supersymmetric theory has to be elaborated on nonholonomic (super) manifolds and bundles determined by non-integrable superdistributions with additional constraints on (super) field dynamics and geometric evolution equations. We also consider generalizations of Perelman's functionals using such nonholonomic variables which result in the decoupling of geometric flow equations and Ricci soliton equations with supergravity modifications of the $R^2$ gravity theory. As such, it is possible to construct exact non-homogeneous and locally aniso...

  11. Patient satisfaction with medical care

    M. A. Sadovoy

    2017-01-01

    Full Text Available Patients’ evaluation of medical care is becoming more and more important due to expanding patient-centered care. For this purpose a complex index of patient satisfaction with healthcare is used. This parameter reflects the correspondence of actual healthcare services to patient’s expectations that were formed under the influence of cultural, social, economic factors, and personal experience of each patient. Satisfaction is a subjective parameter, thus, a grade of satisfaction is barely connected with quality of healthcare services itself. Moreover, medical organizations should always take into account specific features of each patient, since they can have an influence on customer attitude to medical services.This article comprises the review of publications studying determinants of patient satisfaction. In the course of the study, we analyzed data received by research teams from different countries.According to the review, we made some conclusions. First, determinants of patient satisfaction with healthcare can be divided in two groups. The first group of factors includes patients’ characteristics such as age, gender, ethnical and cultural features. However, researches from different countries revealed that there is a difference in the importance of factors belonging to this group and their influence on satisfaction of certain patient cohorts. The second group includes factors that belong to the process of healthcare services delivery and its organization. Moreover, it was found that patient satisfaction level is changing in a waveform. Thus, medical organization should not only try to increase patient satisfaction level but also maintain it. AS a result, it necessary to monitor patient satisfaction with healthcare services. That is why there is a distinct need for the development of a new tool or adaptation of existing instrument of satisfaction measurement, which would be unitized for all medical organizations in the Russian Federation

    There is a surge of interest in subjective well-being (SWB), which concerns how individuals feel about their happiness. Life satisfaction tends to be influenced by individual psychological traits and external social factors. The aim of this study was to examine the relationship between individual character and SWB. Data from 3522 university students were analyzed in this study. Character profiles were evaluated using the Temperament and Character Inventory-Revised Short version (TCI-RS). Life satisfaction was assessed using the Satisfaction with Life Scale (SWLS). All statistical tests regarding the correlations between each character profile and life satisfaction were conducted using ANOVAs, t-tests, multiple linear regression models and correlation analyses. The creative (SCT) profile was associated with the highest levels of life satisfaction, whereas the depressive (sct) profile was associated with the lowest levels of life satisfaction. Additionally, high self-directedness, self-transcendence and cooperation were associated with high life satisfaction. The results of gender-adjusted multiple regression analysis showed that the effects of self-directedness were the strongest in the assessment of one's quality of life, followed by self-transcendence and cooperativeness, in that order. All of the three-character profiles were significantly correlated with one's quality of life, and the character profiles of TCI-RS explained 27.6% of life satisfaction in total. Among the three-character profiles, the self-directedness profile was most associated with life satisfaction. Our study was cross-sectional, and self-reported data from students at a single university were analyzed. The results of this study showed that, among the character profiles, the effects of self-directedness were the strongest for predicting life satisfaction. Copyright © 2014 Elsevier Inc.

    2012-12-01

    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. A core element of this infrastructure is a master catalog of research vessels, cruises, sensor systems, underway datasets, navigation products, field reports, event logs, file formats, people, organizations, and funding awards that is maintained uniformly across the research fleet. All NSF-supported vessel operators now submit their underway cruise data and documentation directly to R2R, per the revised Division of Ocean Sciences (OCE) Sample and Data Policy published in 2011. R2R ingests this content into the fleet catalog, assigning globally unique and persistent identifiers at the cruise, dataset, and file (granule) levels. The catalog is aligned with community-standard vocabularies, working collaboratively with the NOAA Data Centers, UNOLS Office, and pan-European SeaDataNet project; and includes links to related data at other inter/national repositories. In response to community demand, we are extending the catalog to include instrument-specific metadata such as installation details, patch tests, and calibration results. The entire R2R catalog is published on the Web as "Linked Data", making it easily accessible to encourage integration with other repositories. Selected content is also published in formal metadata records according to ISO and W3C standards, suitable for submission to long-term archives. We are deploying both faceted (classification/filter) and Web map-based browse and search interfaces.

    1996-01-01

    Random matrix theory (RMT) provides a common mathematical formulation of distinct physical questions in three different areas: quantum chaos, the 1-d integrable model with the $1/r^2$ interaction (the Calogero-Sutherland-Moser system), and 2-d quantum gravity. We review the connection of RMT with these areas. We also discuss the method of loop equations for determining correlation functions in RMT, and smoothed global eigenvalue correlators in the 2-matrix model for gaussian orthogonal, unitary and symplectic ensembles.

    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 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 placenta accreta, suggesting a possible role of apoptosis in abnormal trophoblast invasion.

    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/

    Previous work has shown that if an attractive 1/r^2 potential is regularized at short distances by a spherical square-well potential, renormalization allows multiple solutions for the depth of the square well. The depth can be chosen to be a continuous function of the short-distance cutoff R, but it can also be a log-periodic function of R with finite discontinuities, corresponding to a renormalization group (RG) limit cycle. We consider the regularization with a delta-shell potential. In this case, the coupling constant is uniquely determined to be a log-periodic function of R with infinite discontinuities, and an RG limit cycle is unavoidable. In general, a regularization with an RG limit cycle is selected as the correct renormalization of the 1/r^2 potential by the conditions that the cutoff radius R can be made arbitrarily small and that physical observables are reproduced accurately at all energies much less than hbar^2/mR^2.

    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.

    Cancer cell migration is involved in tumour metastasis. However, the relationship between calcium signalling and cancer migration is not well elucidated. In this study, we used the human lung adenocarcinoma A549 cell line to examine the role of endoplasmic reticulum protein 44 (ERP44), which has been reported to regulate calcium release inside of the endoplasmic reticulum (ER), in cell migration. We found that the inositol 1,4,5-trisphosphate receptors (IP3Rs/ITPRs) inhibitor 2-APB significantly inhibited A549 cell migration by inhibiting cell polarization and pseudopodium protrusion, which suggests that Ca2+ is necessary for A549 cell migration. Similarly, the overexpression of ERP44 reduced intracellular Ca2+ release via IP3Rs, altered cell morphology and significantly inhibited the migration of A549 cells. These phenomena were primarily dependent on IP3R2 because wound healing in A549 cells with IP3R2 rather than IP3R1 or IP3R3 siRNA was markedly inhibited. Moreover, the overexpression of ERP44 did not affect the migration of the human neuroblastoma cell line SH-SY5Y, which mainly expresses IP3R1. Based on the above observations, we conclude that ERP44 regulates A549 cell migration mainly via an IP3R2-dependent pathway.

    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.

    2011-01-01

    Constraint satisfaction problems (CSPs) lie at the heart of many modern industrial and commercial tasks. An important new collection of CSPs has recently been emerging that differ from classical problems in that they impose constraints on the class of algorithms that can be used to solve them. In computer network applications, these constraints arise as the variables within the CSP are located at physically distinct devices that cannot communicate. At each instant, every variable only knows if all its constraints are met or at least one is not. Consequently, the CSP's solution must be found using a decentralized approach. Existing algorithms for solving CSPs are either centralized or distributed, both of which violate these algorithmic constraints. In this article we present the first algorithm for solving CSPs that fulfills these new requirements. It is fully decentralized, making no use of a centralized controller or message-passing between variables. We prove that this algorithm converges with probability ...

    The NSF-funded Rolling Deck to Repository (R2R) project is working with U.S. academic research vessel operators to ensure the documentation and preservation of data from routine “underway” (meteorological, geophysical, and oceanographic) sensor systems. A standard pipeline is being developed in which data are submitted by vessel operators directly to a central repository; inventoried in an integrated fleet-wide catalog; organized into discrete data sets with persistent unique identifiers; associated with essential cruise-level metadata; and delivered to the National Data Centers for archiving and dissemination. Several vessels including Atlantis, Healy, Hugh R. Sharp, Ka'imikai-O-Kanaloa, Kilo Moana, Knorr, Marcus G. Langseth, Melville, Oceanus, Roger Revelle, and Thomas G. Thompson began submitting data and documentation to R2R during the project’s pilot phase, and a repository infrastructure has been established. Cruise metadata, track maps, and data inventories are published at the R2R Web portal, with controlled vocabularies drawn from community standards (e.g. International Council for the Exploration of the Sea (ICES) ship codes). A direct connection has been established to the University-National Oceanographic Laboratory System (UNOLS) Ship Time Request and Scheduling System (STRS) via Web services to synchronize port codes and cruise schedules. A secure portal is being developed where operators may login to upload sailing orders, review data inventories, and create vessel profiles. R2R has established a standard procedure for submission of data to the National Geophysical Data Center (NGDC) that incorporates persistent unique identifiers for cruises, data sets, and individual files, using multibeam data as a test bed. Once proprietary holds are cleared and a data set is delivered to NGDC, the R2R catalog record is updated with the URL for direct download and it becomes immediately available to integration and synthesis projects such as the NSF

    Scientific event logs, used by the science party to record scientific sampling events that occur during a research cruise, have been used in various ways for decades. An event log is very important for documenting the occurrence of a sampling event and its location, time, relative sequence, and related details. Event logging, done well, can provide important documentation about scientific data collected during a cruise, and enable more efficient use of those data by cruise participants and future researchers. When the resultant event log is a digital data file, with content generated programmatically and controlled by term vocabularies, it becomes an even more valuable addition to the full complement of data sets generated during the cruise. However, such a tool is only effective if it is used. Through field testing, several key factors were identified that encourage the use of such a tool: the ability to customize the tool to represent the science implementation plan, proposed sampling scheme, cruise personnel and instrumentation; the ability to retrieve date, time and location data automatically from the shipboard network and the ability to enter events quickly and from any location on the ship. This presentation provides an overview of both the current version 1 and soon to be released version 2 of the Rolling Deck to Repository (R2R) research cruise Event Logger system. The R2R Event Logger application is built upon a pre-existing, open-source, weblog product called ELOG (ELOG URL: http://midas.psi.ch/elog/). We provide an oceanographer's view of the full process by which: 1) the R2R Event Logger application is configured and tested to meet the unique needs of a research cruise; 2) the R2R project works with the ship operator to install the Event Logger on the ship designated for the cruise, 3) the Event Logger is configured to automatically retrieve location, time, and other pertinent information from the shipboard network; 4) a copy of the event log file is

  11. Synaptic AMPA receptor subunit trafficking is independent of the C terminus in the GluR2-lacking mouse.

    Glutamate is the primary excitatory neurotransmitter in the brain, and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) type glutamate receptors mediate most fast synaptic transmission. AMPA receptors are tetrameric assemblies composed from four possible subunits (GluR1-4). In hippocampal pyramidal cells, AMPA receptors are heteromeric receptors containing the GluR2 subunit and either GluR1 or GluR3. It is generally accepted that the trafficking of GluR1/GluR2 receptors to synapses requires activity, whereas GluR2/GluR3 receptors traffic constitutively. It has been suggested that the trafficking is governed by the cytoplasmic C termini of the subunits. Because the basis for this theory relied on the introduction of unnatural, homomeric, calcium-permeable AMPA receptors, we have used the GluR2(-/-) knock out mouse to determine whether the expression of mutated forms of GluR2 can rescue WT synaptic responses. We find that GluR2, lacking its entire C terminus, or a GluR2 chimera containing the C terminus of GluR1, is capable of trafficking to the synapse in the absence of activity. These findings suggest that the GluR2 C terminus is not required for GluR2 synaptic insertion.

  12. 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.

    Full Text Available There are few studies that focus on the influence that contextual aspects have in marital satisfaction (Meléndez, Aleixandre,& Saez, 1993.However, nowadays the reasons for a divorce are related to the actual social situation (Khalfani-Cox, 2009. Thus, the aim of this study is to identify contextual aspects that are associ-ated with marital satisfaction; in order to accomplish this objective, we conducted two studies. The purpose of the first study was to identify recent context aspects that influence marital satisfaction throughout an open question, which was ap-plied to 131 people. The results indicate that the dimensions of economic, labor time, home safety, stress in the environment, and the place where they live influ-ence marital satisfaction. In the second study, based on the information obtained previously, we formed indicators that were applied together with a scale of mari-tal satisfaction to105 couples. The results show that the context is closely related to marital satisfaction. In addition, the results determine that men give greater importance to the economic and employment situation than women do. Overall, this study indicates that sex differences prove that the roles and cultural expecta-tions have remained in the dynamics of the relationship and thus influence the assessment of marital satisfaction.

    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

    Full Text Available Changes in today's business environment require companies to orient to strategic marketing. The company accepting strategic marketing has a proactive approach and focus on continuous review and reappraisal of existing and seeking new strategic business areas. Difficulties in achieving target profit and growth require turning marketing from the dominant viewpoint of the tangible product to creating superior value and developing relationships with customers. Value orientation implies gaining competitive advantage through continuous research and understanding of what value represents to the consumers and discovering new ways to meet their required values. Strategic marketing investment requires that the investment in the creation of values should be regularly reviewed in order to ensure a focus on customers with high profit potential and environmental value. This increases customer satisfaction and retention and long-term return on investment of companies.

    The objective of this study was to gain a better understanding of the multiple determinants to food satisfaction from a consumer perspective. The study includes two focus groups with a total of 20 consumers varying in gender, age, employment and food interest. The results were divided into sections based on the main themes that arose from analysing the focus groups; i) sensory properties, ii) physical wellbeing, iii) expectations and desires, iv) the food context and v) comparison of the importance of the various determinants to satisfaction. Factors important for food satisfaction appear before as well as during and after intake. Before intake, the important factors are; expectations and desires based on memories about previous food experiences and the context in which the food is perceived. Physical wellbeing was mentioned important for the feeling of satisfaction, included in physical wellbeing is the experience of an appropriate energy level after intake. In general the sensory experience seems to be the primary determinant to satisfaction. The hedonic experience of eating could be enhanced by the social company and knowledge about the food inclusive health value and origin. Findings from the study will prospectively be used to develop a questionnaire. The questionnaire will be applied in case studies to measure factors influential in food satisfaction.

    To estimate the impact of nursing home work practices, specifically compensation and working conditions, on job satisfaction of nursing assistants employed in nursing homes. Data are from the 2004 National Nursing Assistant Survey, responses by the nursing assistants' employers to the 2004 National Nursing Home Survey, and county-level data from the Area Resource File. Multinomial logistic regression was used to estimate effects of compensation and working conditions on nursing assistants' overall job satisfaction, controlling for personal characteristics and local labor market characteristics. Wages, benefits, and job demands, measured by the ratio of nursing assistant hours per resident day, were associated with job satisfaction. Consistent with previous studies, job satisfaction was greater when nursing assistants felt respected and valued by their employers and had good relationships with supervisors. Nursing assistants were more satisfied when they had enough time to complete their work, when their work was challenging, when they were not subject to mandatory overtime, and where food was not delivered to residents on trays. This is the first investigation of nursing assistant job satisfaction using a nationally representative sample of nursing assistants matched to information about their employing nursing homes. The findings corroborate results of previous studies in showing that compensation and working conditions that provide respect, good relationships with supervisors, and better staffing levels are important to nursing assistant job satisfaction.

    Purpose Although extensive research exists regarding job satisfaction, many previous studies used a more restrictive, quantitative methodology. The purpose of this qualitative study is to capture the perceptions of hospital nurses within generational cohorts regarding their work satisfaction. Design/methodology/approach A preliminary qualitative, phenomenological study design explored hospital nurses' work satisfaction within generational cohorts - Baby Boomers (1946-1964), Generation X (1965-1980) and Millennials (1981-2000). A South Florida hospital provided the venue for the research. In all, 15 full-time staff nurses, segmented into generational cohorts, participated in personal interviews to determine themes related to seven established factors of work satisfaction: pay, autonomy, task requirements, administration, doctor-nurse relationship, interaction and professional status. Findings An analysis of the transcribed interviews confirmed the importance of the seven factors of job satisfaction. Similarities and differences between the generational cohorts related to a combination of stages of life and generational attributes. Practical implications The results of any qualitative research relate only to the specific venue studied and are not generalizable. However, the information gleaned from this study is transferable and other organizations are encouraged to conduct their own research and compare the results. Originality/value This study is unique, as the seven factors from an extensively used and highly respected quantitative research instrument were applied as the basis for this qualitative inquiry into generational cohort job satisfaction in a hospital setting.

    Prevailing views of marital functioning generally adopt the view that marital problems predict decreases in marital satisfaction, but alternative theoretical perspectives raise the possibility that lowered satisfaction can also predict increases in problems. The current study sought to integrate and compare these perspectives by examining the bidirectional cross-lagged associations between newlyweds' reports of their marital satisfaction and marital problems over the first 4 years of marriage. Using annual assessments from 483 heterosexual newlywed couples, we find evidence for problem-to-satisfaction linkages as well as satisfaction-to-problem linkages. Satisfaction was a stronger predictor of marital problems early in marriage but not as time passed; by Year 4 only problem-to-satisfaction linkages remained significant. These findings are consistent with the idea that couples with more problems go on to report lower levels of satisfaction and couples with lower levels of satisfaction go on to report more marital problems. This dynamic interplay between global judgments about relationship satisfaction and ongoing specific relationship difficulties highlights the value of examining bidirectional effects to better understand marital functioning over time. © 2016 Family Process Institute.

    parts of business ethics given prominence to especially one term, namely `value'. The question that interests me is the following: What does the articulation of ethics and morality in terms of values mean for ethics and morality as such. Or, to put the question in a more fashionably way: What...... is the value of value for morality and ethics?To make things a bit more precise, we can make use of the common distinction between ethics and morality, i.e. that morality is the immediate, collective and unconscious employment of morals, whereas ethics is the systematic, individual and conscious reflections...

    Fiese, B H; Tomcho, T J

    2001-12-01

    This study examined the relation between marital satisfaction and religious holiday ritual practices. One hundred twenty couples, married 9 years on average, completed measures of religious holiday practices (current family and family-of-origin) and marital satisfaction. Couples were interviewed about how important religion was to their family life. Marital satisfaction was related to religious holiday rituals beyond a global indication of religiousness. A different pattern was found for husbands and wives, with husbands' satisfaction more closely linked to ritual meaning and wives' satisfaction associated with routine practices. Family-of-origin rituals were connected across generations. Wives' marital satisfaction was related to husbands' report of religious holiday rituals but not the converse. Results are discussed in terms of how rituals affirm relationships, connect values and beliefs, and may have differential meaning for men and women.

  10. Factors influencing job satisfaction in post-transition economies: the case of the Czech Republic.

    2015-01-01

    This paper presents an analysis of factors influencing job satisfaction in post-transition economies on the example of the Czech Republic. Our research shows that women reported higher levels of job satisfaction compared to men. Education proved to be statistically significant in one of three indicators of job satisfaction. Personal income and workplace relationships proved to be positively and significantly related to all the three indicators of job satisfaction. Most of the occupational dummies were significantly related to two out of three indicators of job satisfaction. In addition, we found that Czech entrepreneurs enjoy and value their job, which indicates strong self-selection for doing business in post-transition economies. However, human capital expressed by the level of education was significant factor for job satisfaction, meaning that well-educated people might not be satisfied with their jobs or feel that their education and experience are wasted in the market economy.

  11. 1r2dinv: A finite-difference model for inverse analysis of two dimensional linear or radial groundwater flow

    Science.gov (United States)

    Bohling, G.C.; Butler, J.J.

    2001-01-01

    We have developed a program for inverse analysis of two-dimensional linear or radial groundwater flow problems. The program, 1r2dinv, uses standard finite difference techniques to solve the groundwater flow equation for a horizontal or vertical plane with heterogeneous properties. In radial mode, the program simulates flow to a well in a vertical plane, transforming the radial flow equation into an equivalent problem in Cartesian coordinates. The physical parameters in the model are horizontal or x-direction hydraulic conductivity, anisotropy ratio (vertical to horizontal conductivity in a vertical model, y-direction to x-direction in a horizontal model), and specific storage. The program allows the user to specify arbitrary and independent zonations of these three parameters and also to specify which zonal parameter values are known and which are unknown. The Levenberg-Marquardt algorithm is used to estimate parameters from observed head values. Particularly powerful features of the program are the ability to perform simultaneous analysis of heads from different tests and the inclusion of the wellbore in the radial mode. These capabilities allow the program to be used for analysis of suites of well tests, such as multilevel slug tests or pumping tests in a tomographic format. The combination of information from tests stressing different vertical levels in an aquifer provides the means for accurately estimating vertical variations in conductivity, a factor profoundly influencing contaminant transport in the subsurface. ?? 2001 Elsevier Science Ltd.

    Full Text Available Purpose: The aim of this study is to review and summarize the main satisfaction scales used in publications about human Resource Management and educational research, in order to adapt the satisfaction scales of the Job Diagnostic Survey (JDS to higher education and validate it with a sample of university students and to assess the concept of satisfaction in two different ways: as a single-item measure, with a global indicator and as a multi-item measure, analyzed as a global model and composed by several scales. Design/methodology/approach: Confirmatory factor analysis with maximum likelihood, using structural equations model, was employed to assess the model fit in 152 business management undergraduates. Findings and Originality/value: The satisfaction model measured as multi-item scale present an acceptable fit. Even though, some of the satisfaction scales did not present a satisfactory fit, they can be used and interpreted independently with carefulness. Nevertheless, the satisfaction single-item scale presents a better fit and has been validated as a simpler and less costly measure of satisfaction. Originality/value: In the current process of change that is taking place in universities according to the plan developed by the European Space of higher Education, validated instruments as the satisfaction scale of JDS, adapted to teaching, may facilitate this process through the diagnosis, and follow-up of changes in satisfaction levels in university classrooms.

    MYB transcription factors of the R2R3-MYB family have been shown to play important roles in many plant processes. A sugarcane R2R3-MYB gene (ScMYB2) and its two alternative forms of transcript (ScMYB2S1 and ScMYB2S2) were identified in this study. The deduced protein of ScMYB2S1 is a typical plant R2R3-MYB protein, while ScMYB2S2 encodes a truncated protein. Real-time qPCR analysis revealed that ScMYB2S1 is suppressed under PEG-simulated drought stress in sugarcane, while ScMYB2S2 is induced at later treatment stage. A senescence symptom was observed when ScMYB2S1 was injected into tobacco leaves mediated by Agrobacterium, but no symptom for ScMYB2S2. Further investigation showed that the expression levels of 4 senescence-associated genes, NtPR-1a, NtNYC1, NtCAT3 and NtABRE, were markedly induced in tobacco leaves after ScMYB2S1-injection, while they were not sensitive to ScMYB2S2-injection. Moreover, MDA and proline were also investigated after injection. Similarly, MDA and proline levels were induced by ABA and ScMYB2S1, while inhibited by ScMYB2S2. We propose that ScMYB2, by alternatively splicing two transcripts (ScMYB2S1 and ScMYB2S2), is involved in an ABA-mediated leaf senescence signaling pathway and play positive role in respond to drought-induced senescence in sugarcane. The results of this study provide information for further research in sugarcane stress processes. PMID:28167824

    Bulb color is an important consumer trait for onion (Allium cepa L., Allioideae, Asparagales). The bulbs accumulate a range of flavonoid compounds, including anthocyanins (red), flavonols (pale yellow), and chalcones (bright yellow). Flavonoid regulation is poorly characterized in onion and in other plants belonging to the Asparagales, despite being a major plant order containing many important crop and ornamental species. R2R3-MYB transcription factors associated with the regulation of distinct branches of the flavonoid pathway were isolated from onion. These belonged to sub-groups (SGs) that commonly activate anthocyanin (SG6, MYB1) or flavonol (SG7, MYB29) production, or repress phenylpropanoid/flavonoid synthesis (SG4, MYB4, MYB5). MYB1 was demonstrated to be a positive regulator of anthocyanin biosynthesis by the induction of anthocyanin production in onion tissue when transiently overexpressed and by reduction of pigmentation when transiently repressed via RNAi. Furthermore, ectopic red pigmentation was observed in garlic (Allium sativum L.) plants stably transformed with a construct for co-overexpression of MYB1 and a bHLH partner. MYB1 also was able to complement the acyanic petal phenotype of a defined R2R3-MYB anthocyanin mutant in Antirrhinum majus of the asterid clade of eudicots. The availability of sequence information for flavonoid-related MYBs from onion enabled phylogenetic groupings to be determined across monocotyledonous and dicotyledonous species, including the identification of characteristic amino acid motifs. This analysis suggests that divergent evolution of the R2R3-MYB family has occurred between Poaceae/Orchidaceae and Allioideae species. The DNA sequences identified will be valuable for future analysis of classical flavonoid genetic loci in Allium crops and will assist the breeding of these important crop species.

    The aim of this study was to examine the relationship between athletes' perceptions of role ambiguity and satisfaction. The relationship between these multidimensional constructs was investigated at the beginning and at the end of the season, as well as from early season to end of season. Consistent with the a prioi hypothesis, concurrent analyses revealed lower perceived role ambiguity was associated with higher athlete satisfaction. Specifically, role ambiguity, as represented by the dimension Scope of Responsibilities on offence, was significantly related to the leadership facets of athlete satisfaction (i.e. ability utilization, strategy, and training/instruction) both at the beginning and at the end of the season. However, contrary to expectations, role ambiguity at the beginning of the season was not predictive of athlete satisfaction at the end of the season. The implications of the results are discussed and future research is suggested.

    2000-04-01

    Since Asian Americans have demographic and labor force characteristics more similar to Euro-Americans than African Americans, one might predict that their job satisfaction would be more like the former than the latter. And, because Asian Americans originating from different countries are heterogeneous in language, culture, and recency of immigration, one might predict that they may report obtaining different amounts of satisfaction from their jobs. However, data from 21 nationally representative opinion surveys from 1972 through 1996 suggest the opposite. Asian Americans (n = 199) reported job satisfaction more like African Americans (n = 1,231) than Euro-Americans (n = 10,709), and Asian Americans from China (n = 53), Japan (n = 44), India (n = 55), and the Philippines (n = 47) reported similar job satisfaction. These differences persisted when age, education, occupation, and personal income were held constant.

    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.

    2009-01-01

    This paper analyzes the kinematic optimization design of the 4R 2-DOF parallel mechanism taking into account the force transmissibility. Three indices are introduced to reflect the force transmissibility. Based on these indices and their performance charts, the optimization design process with respect to the work-space is presented in detail. The results show that the designed mechanism is not only far from every sin-gularity but also has good force transmissibility in its workspace. These kinematic optimization indices can be extended to other parallel mechanisms.

    Cerebrovascular reactivity (CVR)-weighted blood-oxygenation-level-dependent magnetic resonance imaging (BOLD-MRI) experiments are frequently used in conjunction with hyperoxia. Owing to complex interactions between hyperoxia and hypercapnia, quantitative effects of these gas mixtures on BOLD responses, blood and tissue R2*, and blood oxygenation are incompletely understood. Here we performed BOLD imaging (3 T; TE/TR=35/2,000 ms; spatial resolution=3 × 3 × 3.5 mm3) in healthy volunteers (n=12; age=29±4.1 years) breathing (i) room air (RA), (ii) normocapnic–hyperoxia (95% O2/5% N2, HO), (iii) hypercapnic–normoxia (5% CO2/21% O2/74% N2, HC-NO), and (iv) hypercapnic–hyperoxia (5% CO2/95% O2, HC-HO). For HC-HO, experiments were performed with separate RA and HO baselines to control for changes in O2. T2-relaxation-under-spin-tagging MRI was used to calculate basal venous oxygenation. Signal changes were quantified and established hemodynamic models were applied to quantify vasoactive blood oxygenation, blood–water R2*, and tissue–water R2*. In the cortex, fractional BOLD changes (stimulus/baseline) were HO/RA=0.011±0.007; HC-NO/RA=0.014±0.004; HC-HO/HO=0.020±0.008; and HC-HO/RA=0.035±0.010; for the measured basal venous oxygenation level of 0.632, this led to venous blood oxygenation levels of 0.660 (HO), 0.665 (HC-NO), and 0.712 (HC-HO). Interleaving a HC-HO stimulus with HO baseline provided a smaller but significantly elevated BOLD response compared with a HC-NO stimulus. Results provide an outline for how blood oxygenation differs for several gas stimuli and provides quantitative information on how hypercapnic BOLD CVR and R2* are altered during hyperoxia.

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

    We study Lagrangian submanifolds foliated by (n-1)-spheres in R2n for n≥3. We give a general parametrization for such submanifolds, and refine that description when the submanifold is special Lagrangian, self-similar, Hamiltonian stationary or has mean curvature vector of constant length. In all these cases, the submanifold is centered, i.e. invariant under the action of SO(n). It suffices then to solve a simple ODE in two variables to describe the geometry of the solutions.

    2012-10-01

    Full Text Available This article deals with the significance of autonomy and relatedness as central needs in intimate relationships. It examines the influences of need satisfaction on relationship quality and progressive union formation (“institutionalisation” processes of intimate relationships. Using a random sample of 1,914 couples in a longitudinal, dyadic survey design, we ascertained the actor and partner effects of autonomy and relatedness on relationship quality and the union formation process. A cluster analysis resulted in four types of relationship need satisfaction, distinguished by high values in both domains, high values in only one of the domains, or low need satisfaction in both domains. Balanced fulfilment of autonomy and relatedness predicts the comparatively highest values of relationship satisfaction and future orientation (commitment. Moreover, low need satisfaction in relationships reduces the progress of union formation processes (cohabitation, marriage, childbirth. Women demonstrate more intense actor and partner effects of relationship need satisfaction than men.

  3. Distinct human and mouse membrane trafficking systems for sweet taste receptors T1r2 and T1r3.

    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.

    2016-01-01

    Conventional overconstrained parallel manipulators have been widely studied both in industry and academia, however the structural synthesis of hybrid mechanisms with additional constraints is seldom studied, especially for the four degrees of freedom(DOF) hybrid mechanisms. In order to develop a manipulator with additional constraints, a class of important spatial mechanisms with coupling chains(CCs) whose motion type is two rotations and two translations(2R2T) is presented. Based on screw theory, the combination of different types of limbs which are used to construct parallel mechanisms and coupling chains is proposed. The basic types of the general parallel mechanisms and geometric conditions of the kinematic chains are given using constraint synthesis method. Moreover, the 2R2T motion pattern hybrid mechanisms which are derived by adding coupling chains between different serial kinematic chains(SKCs) of the corresponding parallel mechanisms are presented. According to the constraint analysis of the mechanisms, the movement relationship of the moving platform and the kinematic chains is derived by disassembling the coupling chains. At last, fourteen novel hybrid mechanisms with two or three serial kinematic chains are presented. The proposed novel hybrid mechanisms and construction method enrich the family of the spatial mechanisms and provide an instruction to design more complex hybrid mechanisms.

  5. Dark matter and inflation in R + ζR2 supergravity

    As is well known, the gravitational degrees of freedom contained in R + ζR2 (super)gravity lead to Starobinsky's potential, in a one-field setting for inflationary Cosmology that appears favored by Planck data. In this letter we discuss another interesting aspect of this model, related to gravitino production, with emphasis on the corresponding mass spectrum. Assuming that supersymmetry is broken at a very high scale, Super Heavy Gravitino Dark Matter (SHGDM) and Starobinsky's inflation can be coherently unified in a R + ζR2 supergravity. Gravitinos are assumed to be the Lightest Supersymmetric Particles (LSP) and are non-thermally produced during inflation, in turn originated by a scalar with a Starobinsky's potential. Gravitino mass runs with the inflaton field, so that a continuous spectrum of superheavy gravitinos emerges. The theory is implemented with a U(1)R gauge symmetry. However, in a string UV completion, U(1)R-symmetry can be broken by non-perturbative string instantons, while for consistency of our scenario U(1)R gauge symmetry breaking must be broken in order to generate a soft mass terms for the gravitino and gauginos. R-parity violating operators can be generated at non-perturbative level. Gravitinos can decay into very energetic neutrinos and photons in cosmological time scale, with intriguing implications for high energy cosmic rays experiments.

    The R2PdSi3 intermetallic compounds have been reported to crystallize in a hexagonal AlB2-derived structure, with the rare earth atoms on the Al sites and Pd and Si atoms randomly distributed on the B sites. However, the intricate magnetic properties observed in the series of compounds have always suggested complications to the assumed structure. To clarify the situation, x-ray and neutron diffraction measurements were performed on the heavy rare earth compounds with R=Gd, Tb, Dy, Ho, Er, Tm, which revealed the existence of a crystallographic superstructure. The superstructure features a doubled unit cell in the hexagonal basal plane and an octuplication along the perpendicular c direction with respect to the primitive cell. No structural transition was observed between 300 and 1.5 K. Extended x-ray absorption fine structure (EXAFS) analysis as well as density functional theory (DFT) calculations were utilized to investigate the local environments of the respective atoms. In this paper the various experimental results will be presented and it will be shown that the superstructure is mainly due to the Pd-Si order on the B sites. A structure model will be proposed to fully describe the superstructure of Pd-Si order in R2PdSi3. The connection between the crystallographic superstructure and the magnetic properties will be discussed in the framework of the presented model.

    This paper provides an overview of the ARCADE-R2 experiment, a technology demonstrator that aimed to prove the feasibility of small-scale satellite and/or aircraft systems with automatic (a) attitude determination, (b) control and (c) docking capabilities. The experiment embodies a simplified scenario in which an unmanned vehicle mock-up performs rendezvous and docking operations with a fixed complementary unit. The experiment is composed by a supporting structure, which holds a small vehicle with one translational and one rotational degree of freedom, and its fixed target. The dual system features three main custom subsystems: a relative infrared navigation sensor, an attitude control system based on a reaction wheel and a small-scale docking mechanism. The experiment bus is equipped with pressure and temperature sensors, and wind probes to monitor the external environmental conditions. The experiment flew on board the BEXUS 17 stratospheric balloon on October 10, 2013, where several navigation-control-docking sequences were executed and data on the external pressure, temperature, wind speed and direction were collected, characterizing the atmospheric loads applied to the vehicle. This paper describes the critical components of ARCADE-R2 as well as the main results obtained from the balloon flight.

    Context. After the release of the gamma-ray source catalog produced by the Fermi satellite during its first two years of operation, a significant fraction of sources still remain unassociated at lower energies. In addition to well-known high-energy emitters (pulsars, blazars, supernova remnants, etc.) theoretical expectations predict new classes of gamma-ray sources. In particular, gamma-ray emission could be associated with some of the early phases of stellar evolution, but this interesting possibility is still poorly understood. Aims. The aim of this paper is to assess the possibility of the Fermi gamma-ray source 2FGL J0607.5-0618c being associated with the massive star forming region Monoceros R2. Methods. A multi-wavelength analysis of the Monoceros R2 region is carried out using archival data at radio, infrared, X-ray, and gamma-ray wavelengths. The resulting observational properties are used to estimate the physical parameters needed to test the different physical scenarios. Results. We confirm the 2FG...

    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.

    Ultracompact (UC) HII regions constitute one of the earliest phases in the formation of a massive star and are characterized by extreme physical conditions (Go>10^5 Habing field and n>10^6 cm^-3). The UC HII Mon R2 is the closest one and therefore an excellent target to study the chemistry in these complex regions. We carried out a 3mm and 1mm spectral survey using the IRAM 30-m telescope towards three positions that represent different physical environments in Mon R2: (i) the ionization front (IF) at (0",0"); two peaks in the molecular cloud (ii) MP1 at the offset (+15",-15") and (iii) MP2 at the farther offset (0",40"). In addition, we carried out extensive modeling to explain the chemical differences between the three observed regions. We detected more than thirty different species. We detected SO+ and C4H suggesting that UV radiation plays an important role in the molecular chemistry of this region. We detected the typical PDR molecules CN, HCN, HCO, C2H, and c-C3H2. While the IF and the MP1 have a chemis...

    We present observations using the Baade Magellan and Canada-France-Hawaii telescopes showing that main-belt comet 324P/La Sagra, formerly known as P/2010 R2, has become active again for the first time since originally observed to be active in 2010-2011. The object appears point-source-like in March and April 2015 as it approached perihelion (true anomaly of ~300 deg), but was ~1 mag brighter than expected if inactive, suggesting the presence of unresolved dust emission. Activity was confirmed by observations of a cometary dust tail in May and June 2015. We find an apparent net dust production rate of <0.1 kg/s during these observations. 324P is now the fourth main-belt comet confirmed to be recurrently active, a strong indication that its activity is driven by sublimation. It now has the largest confirmed active range of all likely main-belt comets, and also the most distant confirmed inbound activation point at R~2.8 AU. Further observations during the current active period will allow direct comparisons o...

    Full Text Available Background:Patient satisfaction with the cosmetic result of spinal fusion surgery was studied in 40 cases of adolescent idiopathic scoliosis.Neutral or dissatisfied patients were compared with satisfied patients in several physical and psychological characteristics. The aim of the study was to determine whether adolescents generally report satisfaction with the postoperative appearance of their back after the correction of severe curves and whether preoperative medical and/or psychological factors could distinguish between patients who report satisfaction with the cosmetic surgical result from those who report neutrality or dissatisfaction. Previous reports emphasize the need for medical outcome research that evaluates both patient satisfaction and technical success. Patient satisfaction with spinal surgery has largely been evaluated in retrospective studies and most consistently is related to postoperative cosmesis and degree of curve correction. Methods: 40 adolescents with idiopathic scoliosis without any comorbidity who were 10 years of age or older were studied preoperatively by physical and psychological measurements. Results: Of patients undergoing surgical correction of severe curves, 50% reported satisfaction with the cosmetic result. Neutral or dissatisfied patients were more likely to have a King II or King IV curve types and less correction than satisfied patients. Preoperative psychological difficulties (P< 0.05 and unmet expectations regarding postoperative cosmesis (P<0.05 were more common among neutral or dissatisfied patients. Conclusion: Most adolescents with idiopathic scoliosis expressed satisfaction with the cosmetic surgical result. Preoperative physical characteristics, psychological difficulties, and unrealistic expectations regarding postoperative cosmesis are associated with patient neutrality or dissatisfaction.
