    In its function as a purely financial concept for company assessment, does shareholder value promote short-term thinking or can an enterprise's orientation towards shareholder value be sustainable? What contradictions exist between the yield, security and liquidity of an asset and ethically and ecologically correct behaviour? One of the authors shows why effective environmental protection and a simultaneous increase in shareholder value are both possible and sensible. Especially when the assessment of the future economic chances of an enterprise in a changing ecological frame of reference are being examined, the shareholder value approach is well suited as a conceptional basis - provided it is correctly used. Can shareholders replace environmental policy? This question is asked by another of the authors. Is a 'green' strategy good, simply because it generates more profit? Can green capitalism rescue the world? According to another contributor there is no real contradiction between the shareholder value approach and the stake holder concept. The shareholder value approach is primarily a method for looking at an enterprise from the capital investor's point of view. The stake holder concept can, on the other hand, be assigned to the strategic management category. It shows that enterprises must take account of stake holder requirements in order to permanently be able to reach their goals. A further contribution addresses the role played by pension funds. What responsibility is carried by a pension fund when it invests its assets? What are its objectives? Which role do socially and ecologically-oriented investments play? Is there really a contradiction between economy and ecology? How does a pension fund deal with possible conflicting objectives? Another contributor presents an investment foundation's integrated approach to socially responsible investment: First of all, investments should be made in those enterprises and countries that make exceptional contributions to

    Long-term memory can be adaptive as it allows animals to retain information that is crucial for survival, such as the appearance and location of key resources. This is generally examined by comparing choices of stimuli that have value to the animal with those that do not; however, in nature choices are rarely so clear cut. Animals are able to assess the relative value of a resource via direct comparison, but it remains unclear whether they are able to retain this information for a biologically meaningful amount of time. To test this, captive red-footed tortoises (Chelonoidis carbonaria) were first trained to associate visual cues with specific qualities and quantities of food, and their preferences for the different reward values determined. They were then retested after an interval of 18 months. We found that the tortoises were able to retain the information they had learned about the cues as indicators of relative reward values over this interval, demonstrating a memory for the relative quantity and quality of food over an extended period of time. This is likely to impact directly on an animal's foraging decisions, such as the exploitation of seasonally varying resources, with obvious fitness implications for the individual; however, the implications may also extend to the ecological interactions in which the animal is involved, affecting processes such as herbivory and seed dispersal. © 2017 The Author(s).

  5. Options: the value of flexibilities in long term uranium contracts

    1996-01-01

    It has been commonplace for uranium suppliers to offer utilities long-term contracts with significant quantity flexibilities. These are attractive to the utility for which the consumption of fuel is dependent on variable reactor performance and have given the suppliers an additional competitive tool. The return to a uranium market in which near-term supply is likely to be tight is a disincentive to suppliers to offer new contracts with flexibilities. Typical recent flexibility offers have been significantly less generous than in the past. A methodology is outlined which can be used to give a theoretical estimate of the value of the flexibility provision to the supplier and buyer. It is based on the similarity between flexibility provision and option contracts in the securities and commodity markets. By regarding flexibilities as ''embedded options'' it is possible to apply to them the Black-Scholes option pricing formula as long as the necessary inputs, such as the price of uranium, the loan rate and the volatility, are available. The formula does have its shortfalls, however; in particular, it cannot incorporate the political perturbations that are continually taking place in the uranium industry. (13 figures, 15 references).

    Multi-term fractional diffusion-wave equation along with the homogeneous/non-homogeneous boundary conditions has been solved using the method of separation of variables. It is observed that, unlike in the one term case, solution of multi-term fractional diffusion-wave equation is not necessarily non-negative, and hence does not represent anomalous diffusion of any kind.

    2013-01-01

    According to an influential view in corporate law writings and debates, pressure from shareholders leads companies to take myopic actions that are costly in the long term, and insulating boards from such pressure serves the long-term interests of companies as well as their shareholders. This board insulation claim has been regularly invoked in a wide range of contexts to support existing or tighter limits on shareholder rights and involvement. This paper subjects this view to a comprehensive ...

    Abstract: The economic valuation of ecosystem services is a key policy tool in stemming losses of biological diversity. It is proposed that the loss of ecosystem function and the biological resources within ecosystems is due in part to the failure of markets to recognize the benefits humans derive...... from ecosystems. Placing monetary values on ecosystem services is often suggested as a necessary step in correcting such market failures. We consider the effects of valuing different types of ecosystem services within an economic framework. We argue that provisioning and regulating ecosystem services...

    There is a trend towards value-based health service, striving to cut costs while generating value for the patient. The overall objective comprises higher-quality health services and improved patient safety and cost efficiency. The approach could align with patient-centred care, as it entails a focus on the patient's experience of her or his entire cycle of care, including the use of well-defined outcome measurements. Challenges arise when the approach is applied to health services for people living with long-term complex conditions that require support from various healthcare services. The aim of this work is to critically discuss the value-based approach and its implications for patients with long-term complex conditions. Two cases from clinical practice and research form the foundation for our reasoning, illustrating several challenges regarding value-based health services for people living with long-term complex conditions. Achieving value-based health services that provide the health outcomes that matter to patients and providing greater patient-centredness will place increased demands on the healthcare system. Patients and their informal caregivers must be included in the development and establishment of outcome measures. The outcome measures must be standardized to allow evaluation of specific conditions at an aggregated level, but they must also be sensitive enough to capture each patient's individual needs and goals. Healthcare systems that strive to establish value-based services must collaborate beyond the organizational boundaries to create clear patient trajectories in order to avoid fragmentation. The shift towards value-based health services has the potential to align healthcare-service delivery with patient-centred care if serious efforts to take the patient's perspective into account are made. This is especially challenging in fragmented healthcare systems and for patients with long-term- and multi-setting-care needs.

    It is important to have an accurate assessment of urinary protein when glomerulopathy or kidney injury is suspected. Currently available normal values for the neonate population have limited value, in part because they are based on small populations and obsolete creatinine assays. We have performed a prospective study with the aim to update the normal upper values of the urinary total protein-to-creatinine and albumin-to-creatinine ratios in term newborns. Urine samples were collected from 277 healthy, full-term newborns within the first 48 hours (D0-1) and between 72 and 120 h of life (D3-4). Total protein, albumin, creatinine and osmolality were measured and the upper limit of normal (upper-limit) values determined. At D0-1 and D3-4, the upper-limit values for the total protein-to-creatinine ratio were 1431 and 1205 mg/g (162 and 136 g/mol) and those for the albumin-to-creatinine ratio were 746 and 301 mg/g (84 and 34 g/mol), respectively. The upper-limit values were significantly higher at D0-1 than at D3-4 only for the albumin-to-creatinine ratio. This study determined the upper limit of normal values for urinary total protein-to-creatinine and albumin-to-creatinine ratios in the largest population of newborns studied to date. These values can therefore be considered as the most clinically relevant data currently available for the detection and diagnosis of glomerular injury in daily clinical practice in this population.

    Eighteen parameters of LIMCAL, a comprehensive food chain model for predicting ICRP 26 50-year committed effective dose equivalents to man due to long-term nuclear waste management are reviewed. The parameters are: soil bulk density, plowlayer depth, soil surface layer depth, resusupension factor, atmospheric dust load, deposition velocity, plant interception fraction, plant environmental half-time, translocation factor, time of above-ground exposure, plant yield, holdup time, animals' feed consumption rate, animals' water consumption rate, man's water consumption rate, food type calorie conversion factors, man's total caloric intake rate and food type calorie fractions. LIMCAL has both traditional and unique parameters. The former occur in most of the currently used assessment models for nuclear installations, whereas the latter do not. For each of the parameters of LIMCAL, a suitable generic value for long-term nuclear waste management was determined. Thus, the general literature and the values currently used or recommended by various agencies were reviewed

    Objective: To investigate the short-term prognostic value of thrombus precursor protein (TpP) in patients with unstable angina (UA). Methods: One hundred and ten cases of UA were selected. The TpP was measured by enzyme linked immunosorbent assay (ELISA). The cardiovascular events were observed in 6 months. Results: In the 100 cases of UA, the cardiovascular events were observed in 17 cases. There was an significant difference in three levels of TpP (P<0.05). The risk level was increasing as the increasing of the plasma level of TpP. Conclusion: The level of TpP has certain reference value and plays a role in forecasting of the short-term prognosis of the patients with UA. When the plasma level of TpP increases there is also an increase in OR. (authors)

    Long-term catchment studies are sentinel sites for detecting, documenting, and understanding ecosystem processes and environmental change. The small catchment approach fosters in-depth site-based hydrological, biogeochemical, and ecological process understanding, while a collective network of catchment observatories offers a broader context to synthesize understanding across a range of climates and geologies. The USGS Water, Energy, and Biogeochemical Budgets (WEBB) program is a network of five sites established in 1991 to assess the impact of climate and environmental change on hydrology and biogeochemistry. Like other networks, such as the USDA - Forest Service Experimental Forests and the Czech Geomon network, WEBB exploits gradients of climate, geology, and topography to understand controls on biogeochemical processes. We present examples from each site and some cross-site syntheses to demonstrate how WEBB has advanced catchment science and informed resource management and policy. WEBB has relied on strong academic partnerships, providing long-term continuity for shorter-term academic grants, which have offered rich graduate educational opportunities. Like other sites and networks, the long-term datasets and process understanding of WEBB provide context to detect and interpret change. Without this backdrop, we have no baseline to quantify effects of droughts, floods, and extreme events, and no test sites to validate process-based models. In an era of lean budgets for science funding, the long-term continuity of WEBB and other catchment networks is in jeopardy, as is the critical scientific value and societal benefits they embody.

    To establish reference haematological values (complete blood count) in healthy full-term newborns of Karachi. This is a cross sectional study design based on cord blood sample of 404 newborns and their mothers recruited from Sindh Government Qatar Hospital, Ziauddin University Hospital gole market campus, Sindh Government hospital, Liaquatabad and Chinniot maternity and child hospital. Karachi from July 2006 to April 2008. Both mother's and the new born baby's blood was collected in EDTA containing tubes and analyzed for different haematological parameters. The data entry and analysis was done on computer package SPSS (Statistical Packages of Social Sciences) version 12.0. The results were given in the text as mean, standard deviation and 95% confidence intervals of haematological values (complete blood count). The mean haemoglobin was found to be (14.99 +/- 1.47 gm), which is lower than the standard value described in literature. However the total WBCs count and platelet count were found to be (13.61 +/- 4.23) and (256. 25 +/- 76.54) respectively, which were similar to the other studies. Our values provide reference range for haematological values in healthy newborns of Karachi, for clinical use by our physicians.

    Full Text Available This article analyses the influence of the strategic alternative on the value level increase of the term deposits attracted from the Romanian’s population households, during the period 2012 – Q1/2015, depending on the change of the standards related to deposits granting in RON, EURO and other currencies, but also depending on the aggregate volume of deposits demand at a national level. One-way ANOVA represents the ideal model to emphasize that the average of the term deposits attracted from the population’s households during the last four years is influenced by the strategic alternative used by the credit institutions. The results of this analysis underlined the fact that there is a strong link between the strategic alternative adopted by the banks and the change of the value level of the term deposits intended for the population. The strategies to attract RON deposits proved to be more efficient compared to the strategies adopted by the banks for other currencies.

    Previous work has established that a narrated animation is more effective at communicating a complex biological process (signal transduction) than the equivalent graphic with figure legend. To my knowledge, no study has been done in any subject area on the effectiveness of animations versus graphics in the long-term retention of information, a primary and critical issue in studies of teaching and learning. In this study, involving 393 student responses, three different animations and two graphics-one with and one lacking a legend-were used to determine the long-term retention of information. The results show that students retain more information 21 d after viewing an animation without narration compared with an equivalent graphic whether or not that graphic had a legend. Students' comments provide additional insight into the value of animations in the pedagogical process, and suggestions for future work are proposed.

    Although low levels of free triiodothyronine and high levels of brain natriuretic peptide have been shown as independent predictors of death in chronic heart failure patients, few studies have compared their prognostic values. The aim of this prospective study was to measure free triiodothyronine and brain natriuretic peptide levels and to compare their prognostic values among such patients.A total of 334 patients (mean age, 62 ± 13 yr; 218 men) with ischemic and nonischemic dilated cardiomyopathy were included in the study. The primary endpoint was a major cardiac event.During the follow-up period, 92 patients (28%) experienced a major cardiac event. Mean free triiodothyronine levels were lower and median brain natriuretic peptide levels were higher in patients with major cardiac events than in those without. A significant negative correlation was found between free triiodothyronine and brain natriuretic peptide levels. Receiver operating characteristic curve analysis showed that the predictive cutoff values were triiodothyronine and > 686 pg/mL for brain natriuretic peptide. Cumulative survival was significantly lower among patients with free triiodothyronine 686 pg/mL. In multivariate analysis, the significant independent predictors of major cardiac events were age, free triiodothyronine, and brain natriuretic peptide.In the present study, free triiodothyronine and brain natriuretic peptide had similar prognostic values for predicting long-term prognosis in chronic heart failure patients. These results also suggested that combining these biomarkers may provide an important risk indicator for patients with heart failure.

  6. Realising the Real Benefits of Outsourcing: Measurement Excellence and Its Importance in Achieving Long Term Value

    Science.gov (United States)

    Oshri, Ilan; Kotlarsky, Julia

    These days firms are, more than ever, pressed to demonstrate returns on their investment in outsourcing. While the initial returns can always be associated with one-off cost cutting, outsourcing arrangements are complex, often involving inter-related high-value activities, which makes the realisation of long-term benefits from outsourcing ever more challenging. Executives in client firms are no longer satisfied with the same level of service delivery through the outsourcing lifecycle. They seek to achieve business transformation and innovation in their present and future services, beyond satisfying service level agreements (SLAs). Clearly the business world is facing a new challenge: an outsourcing delivery system of high-value activities that demonstrates value over time and across business functions. However, despite such expectations, many client firms are in the dark when trying to measure and quantify the return on outsourcing investments: results of this research show that less than half of all CIOs and CFOs (43%) have attempted to calculate the financial impact of outsourcing to their bottom line, indicating that the financial benefits are difficult to quantify (51%).

    Full Text Available Congenital hypothyroidism remains one of the most common preventable causes of mental retardation among children. Screening for congenital hypothyroidism remains one of the most cost-effective tools to prevent mental retardation in the population. Umbilical cord blood thyroid-stimulating hormone (TSH levels remain an attractive and a practical step for screening for congenital hypothyroidism. The aims of this study were as follows: (1 to find normative values of cord blood TSH for the study group and (2 to use cord blood TSH levels as a marker for screening of congenital hypothyroidism. Cord blood of 1824 neonates who were of term gestation, weighed >2.5 kg at birth, whose mothers were off thyroid medication were a part of the study group. Umbilical cord blood was collected at the time of delivery and TSH was estimated. All babies who had a cord blood TSH value of >20 mIU/L were called bay on day 7 of life for a full thyroid profile. Cord blood samples of 1824 neonates were tested for TSH. Male–female ratio was 979:845 = 1.15:1. The birth weights ranged between 2.5 and 4.5 kg with an average birth weight of 2.811 kg. Mean (standard deviation TSH value was 7.725 (8.99. TSH values ranged between 1.2 and 100 mIU/ml. TSH values corresponding to the 3rd, 10th, 25th, 50th, 90th, 95th, and 97th percentile were 2.32, 4.05, 5.67, 7.5, 12, 20.63, and 30.88, respectively. Out of the 88 babies recalled for repeat testing, 80 babies only turned up; eventually one turned out to be hypothyroid on repeat testing. The incidence of congenital hypothyroidism in our study was 1 in 1824. To conclude, we can safely use a cutoff of cord blood TSH value of >20 mIU/L for the purpose of screening for congenital hypothyroidism. For logistic angles, a higher cutoff of >30 mIU/L can be used. Large population-based studies are required to establish normative values for cord blood TSH in our country.

  8. The prognostic value of amplitude-integrated EEG in full-term neonates with seizures.

    Dandan Zhang

    Full Text Available Neonatal seizures pose a high risk for adverse outcome in survived infants. While the prognostic value of amplitude-integrated electroencephalogram (aEEG is well established in neonates with encephalopathy and asphyxia, neonatal seizure studies focusing on the direct correlation between early aEEG measurement and subsequent neurologic outcome are scarce. In this study, the prognostic value of aEEG features was systematically analyzed in 143 full-term neonates to identify prognostic indicators of neurodevelopmental outcome. Neonatal aEEG features of background pattern, cyclicity, and seizure activity, as well as the etiology of neonatal seizures, were significantly associated with neurodevelopmental outcome at one year of age. aEEG background pattern was highly associated with neurologic outcomes (χ² = 116.9, followed by aEEG cyclicity (χ² = 87.2 and seizure etiology (χ² = 79.3. Multiple linear regression showed that the four predictors explained 71.2% of the variation in neurological outcome, with standardized β coefficients of 0.44, 0.24, 0.22, and 0.14 for the predictors of aEEG background pattern, cyclicity, etiology, and aEEG seizure activity, respectively. This clinically applicable scoring system based on etiology and three aEEG indices would allow pediatricians to assess the risk for neurodevelopmental impairment and facilitate an early intervention in newborns developing seizures.

    A prospective romantic partner's desirability as a long-term partner may be affected by the values that he or she endorses. However, few studies have examined the effects of "values" on a person's desirability as a long-term partner. We hypothesized that individuals who endorse social values (vs. personal values) will be perceived as more desirable long-term partners (Hypothesis 1) and that the endorsement of social values will be especially desirable in a male (vs. female) long-term partner (Hypothesis 2). The current study employed a 2 (sex of prospective partner: male vs. female) × 2 (values of prospective partner: personal vs. social) × 2 (physical attractiveness of prospective partner: unattractive vs. highly attractive) mixed-model design. Participants were 339 undergraduates (174 men, 165 women), with ages varying between 18 and 33 years ( M = 19.9, SD = 3.6), and mostly in a romantic relationship (53.7%). Participants reported interest in a long-term relationship with prospective partners depicted in four scenarios (within subjects), each varying along the dimensions of values (personal vs. social) and physical attractiveness (unattractive vs. highly attractive). Individuals endorsing personal values (vs. social values) and men (vs. women) endorsing personal values were rated as less desirable as long-term partners. The current research adds to the partner preferences literature by demonstrating that an individual's ascribed values influence others' perceptions of desirability as a long-term partner and that these effects are consistently sex differentiated, as predicted by an evolutionary perspective on romantic partner preferences.

    The aim of our study was to evaluate the long-term prognostic value of transesophageal atrial pacing stress echocardiography (TAPSE) for the prediction of cardiovascular events (myocardial infarction) and mortality at 10-year follow-up. TAPSE was applied as a diagnostic modality in 93 consecutive patients (mean age 45 +/- 8 years) who were diagnosed for the cause of chest pain. Long-term follow-up data were obtained from 87 (94%) patients with a mean duration of follow-up of 92 +/- 4 months. Stress echocardiography was performed using TAPSE with a mean pacing rate of 142 +/- 18/min. Predefined cardiac events occurred during the follow-up period in 45 (52%) patients, including 24 (28%) with hard end points: 10 (12%) with nonfatal myocardial infarction and 17 who died (events overlap). Positive result of TAPSE was found in 47 (54%) patients and among those with positive TAPSE result, 16 died (94% of total mortality) and 21 had a hard event (death or infarction-88% of total prevalence). Survival free from hard events was noted in 37 (92%) patients with negative TAPSE and only in 26 (55%) of those with positive TAPSE ( P = .001). Independent predictive factors for mortality were TAPSE positivity (relative risk with 95% confidence interval [RR/CI] = 39.6 [36.3-42.9], P = .0006) and diabetes (RR/CI = 10.2 [8.6-11.8], P = .0026). Independent predictive factors for myocardial infarction were diabetes (RR/CI = 8.1 [6.3-9.9], P = .0186) and significant coronary stenosis in angiography (RR/CI = 9.0 [6.8-11.2], P = .0479). Independent predictive factors for death or nonfatal myocardial infarction were TAPSE positivity (RR/CI = 12.3 [11.1-13.3], P = .0001) and diabetes (RR/CI = 7.0 [5.8-8.2], P = .0018). Positive TAPSE result carries long-term prognostic information regarding mortality and risk of myocardial infarction that can be used to identify patients requiring more aggressive treatment. Negative TAPSE allows highly accurate definition of low-risk population with

    To examine burnout and work engagement among nurses in Japanese long-term care hospitals and their relation to nurses' and organisational work values, and nurse-organisation congruence of such values. Nursing managers must help improve nurses' well-being; however, no research has considered strategies to improve staff outcomes in long-term care hospitals. We propose that individual nurse's work values and the congruence of these values with those of their organisations may influence burnout and work engagement. We conducted a cross-sectional survey of nurses in long-term care hospitals. Multiple regression analyses were conducted to examine the effects of nurses' work values and nurse-organisation congruence in these values on burnout and work engagement. Higher individual intrinsic and altruistic work values were associated with improvements in nurses' burnout and work engagement. Nurse-organisation non-congruence in altruistic values was associated with lower work engagement, whereas that of intrinsic work values was not associated with either outcome variable. Promoting intrinsic and altruistic work values among nurses could be effective for improving both burnout and work engagement. Opportunities such as case conferences could foster intrinsic and altruistic work values through the review of good care practices and communication between managers/colleagues about feelings and thoughts. © 2018 John Wiley & Sons Ltd.

  13. Reporting on Long-Term Value Creation—The Example of Public Canadian Energy and Mining Companies

    Petra F. A. Dilling

    2016-09-01

    Full Text Available This study empirically analyzes reporting on long-term value creation for Canadian public mining and energy companies. It represents an important first step in determining the quality of reporting and its determinants for large public companies. In this exploratory empirical study, a reporting quality scoring index was developed to measure disclosure quality of long-term value creation reporting. Content analysis was used to examine financial and sustainability reports for a sample of twenty Canadian public mining and energy companies. Corporate disclosure quality scores were then calculated by assessing the quality of reporting in four main categories. The findings suggest that overall disclosure quality on long-term value creation is still low. Companies disclosing higher quality information on long-term value creation are of bigger size, operate in the basic materials sector, have an independent board, are listed in the Dow Jones Sustainability Index, experience higher stock volatility and use more words related to long-term value creation in their annual financial and non-financial reports. In order to increase and restore stakeholder trust and credibility as well as a tool to maintain stability, it is strongly recommended to introduce adequate mandatory standardization resulting in a set of internationally recognized reporting standards as well as a requirement for external assurance of reports.

    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.

    The purpose of the study was to determine the long-term prognostic value of normal adenosine stress cardiac magnetic resonance imaging (CMR) in patients referred for evaluation of myocardial ischemia. We reviewed 300 consecutive patients (age 65 ± 11 years, 74% male) with suspected or known coronary disease and normal wall motion who had undergone adenosine stress CMR negative for ischemia and scar. Most patients were at intermediate risk of coronary artery disease. The end points studied were all causes of mortality and major adverse cardiac events, including cardiac death, myocardial infarction, revascularization, and hospitalization for unstable angina. During a mean follow-up of 5.5 years (mean = 5.4 ± 1.1), 16 patients died because of various causes (cardiac death in 5 patients). Three patients had a nonfatal myocardial infarction, 7 patients were hospitalized for revascularization, and 11 were medically treated for unstable angina. The annual cardiac event rate was 1.3% (0.78% in the first 3 years and 1.9% between the fourth and sixth years). The predictors of major adverse cardiac events in a multivariate analysis model were as follows: advanced age (hazard ratio [HR] 1.15, 95% confidence interval [95% CI] 1.02-1.30), diabetes (HR 17.5, 95% CI 2.2-140), and the habit of smoking (HR 5.9, 95% CI 1.0-35.5). For all causes of mortality, the only predictor was diabetes (HR 11.4, 95% CI 1.76-74.2). Patients with normal stress CMR had an excellent outcome during the 3 years after the study. The cardiac event rate was higher between the fourth and sixth years. Over a 5.5-year period, a low event rate and excellent prognosis occurred in patients with normal adenosine stress CMR. Low- to intermediate-risk patients with a normal CMR are at low risk for subsequent cardiac events. Copyright © 2015 Elsevier Inc. All rights reserved.

  16. Risk analyses in nuclear engineerig, their value in terms of information, and their limits in terms of applicability

    International Nuclear Information System (INIS)

    Heuser, F.W.

    1983-01-01

    This contribution first briefly explains the main pillars of the deterministic safety concept as developed in nuclear engineering, and some basic ideas on risk analyses in general. This is followed by an outline of the methodology and main purposes of risk analyses. The German Risk Study is taken as an example to discuss selected aspects with regard to information value and limits of risk analyses. The main conclusions state that risk analyses are a valuable instrument for quantitative safety evaluation, leading to a better understanding of safety problems and their prevention, and allowing a comparative assessment of various safety measures. They furthermore allow a refined evaluation of a variety of accident parameters and other impacts determining the risk emanating from accidents. The current state of the art in this sector still leaves numerous uncertainties so that risk analyses yield information for assessments rather than for definite predictions. However, the urge for quantifying the lack of knowledge leads to a better and more precise determination of the gaps still to be filled up by researchers and engineers. Thus risk analyses are a useful help in defining suitable approaches and setting up standards, showing the tasks to be fulfilled in safety research in general. (orig./HSCH) [de

    Significant impact on the content, as well as the peculiarities of social rationality of postnonclassical type was made by the following factors: globalization, information revolution, philosophical writings of postmodernists, peculiarities of the post-nonclassical science development. Detailed study of rational activity in the context of post-nonclassical science involves access to the problems associated with the study of value attitude and how it ensures the development of human activity in the direction of the subject, how it transforms this content into a cultural experience that is realized in the system of certain standards, compliance with which determines the social character of the individual, his or her acts of thinking. Value orientations are relatively autonomous, as the representation of values is based primarily on the philosophical views. However, generated views affect the interests, goals, needs, activities, development of all aspects of human life and social structures. In value orientations is objectified not only the experience of the human himself, but also of the historical experience. Embodied in systems of norms, value orientations, and in the criteria, it becomes available to every individual and allows him or her to define the parameters of the cultural activities.

  7. Quasilinear parabolic variational inequalities with multi-valued lower-order terms

    Carl, Siegfried; Le, Vy K.

    2014-10-01

    In this paper, we provide an analytical frame work for the following multi-valued parabolic variational inequality in a cylindrical domain : Find and an such that where is some closed and convex subset, A is a time-dependent quasilinear elliptic operator, and the multi-valued function is assumed to be upper semicontinuous only, so that Clarke's generalized gradient is included as a special case. Thus, parabolic variational-hemivariational inequalities are special cases of the problem considered here. The extension of parabolic variational-hemivariational inequalities to the general class of multi-valued problems considered in this paper is not only of disciplinary interest, but is motivated by the need in applications. The main goals are as follows. First, we provide an existence theory for the above-stated problem under coercivity assumptions. Second, in the noncoercive case, we establish an appropriate sub-supersolution method that allows us to get existence, comparison, and enclosure results. Third, the order structure of the solution set enclosed by sub-supersolutions is revealed. In particular, it is shown that the solution set within the sector of sub-supersolutions is a directed set. As an application, a multi-valued parabolic obstacle problem is treated.

    Despite the research interest in modifying smoking behavior, therapeutic treatments that can produce long-term cessation have not been demonstrated rigorously. A follow-up study of two attitude change experiments (N = 173) examined the effects of a fear appeal, that is, increasing smokers' awareness and appreciation of the highly noxious consequences of smoking. Although this familiar type of information may be an integral component of many smoking treatment programs, its long-term suppressive effect has not been demonstrated in well-controlled experiments. The results disclosed that 3 months and also 1 year after treatment, a high-fear manipulation had increased significantly the percentage of smokers who were able to stop smoking completely.

    Observations and data from long-term experimental watersheds are the foundation of hydrology as a geoscience. They allow us to benchmark process understanding, observe trends and natural cycles, and are pre-requisites for testing predictive models. Long-term experimental watersheds also are places where new measurement technologies are developed. These studies offer a crucial evidence base for understanding and managing the provision of clean water supplies; predicting and mitigating the effects of floods, and protecting ecosystem services provided by rivers and wetlands. They also show how to manage land and water in an integrated, sustainable way that reduces environmental and economic costs. We present a number of compelling examples illustrating how hydrologic process understanding has been generated through comparing hypotheses to data, and how this understanding has been essential for managing water supplies, floods, and ecosystem services today.

  10. Flood effects on an Alaskan stream restoration project: the value of long-term monitoring

    Densmore, Roseann V.; Karle, Kenneth F.

    2009-01-01

    On a nationwide basis, few stream restoration projects have long-term programs in place to monitor the effects of floods on channel and floodplain configuration and floodplain vegetation, but long-term and event-based monitoring is required to measure the effects of these stochastic events and to use the knowledge for adaptive management and the design of future projects. This paper describes a long-term monitoring effort (15 years) on a stream restoration project in Glen Creek in Denali National Park and Preserve in Alaska. The stream channel and floodplain of Glen Creek had been severely degraded over a period of 80 years by placer mining for gold, which left many reaches with unstable and incised streambeds without functioning vegetated floodplains. The objectives of the original project, initiated in 1991, were to develop and test methods for the hydraulic design of channel and floodplain morphology and for floodplain stabilization and riparian habitat recovery, and to conduct research and monitoring to provide information for future projects in similar degraded watersheds. Monitoring methods included surveyed stream cross-sections, vegetation plots, and aerial, ground, and satellite photos. In this paper we address the immediate and outlying effects of a 25-year flood on the stream and floodplain geometry and riparian vegetation. The long-term monitoring revealed that significant channel widening occurred following the flood, likely caused by excessive upstream sediment loading and the fairly slow development of floodplain vegetation in this climate. Our results illustrated design flaws, particularly in regard to identification and analysis of sediment sources and the dominant processes of channel adjustment.

    1965-01-01

    The authors define the notions of use values and price of plutonium. They give a 'simplified parametrized model' simulating the equilibrium of the offer and the demand in time, concerning the plutonium and the price deriving from the relative scarcity of this metal, taking into account the technical and economic operating parameters of the various reactors confronted. This model is simple enough to allow direct computations and establish clear relations between the various parameters. The use of the linear programmes method allows on the other hand a wide extension of the model. This report includes three main parts: I - General description of the study (without detailed calculations) II - Mathematical development of the simplified parametrized model and application (the basic data and the results of the calculations are given) III - Appendices (giving the detailed computations of part II).

    The predictive value of short-term arm pain relief after 'indirect' cervical epidural steroid injection (ESI) for the 1-month treatment response has been previously demonstrated. It remained to be answered whether the long-term response could be estimated by the early post-interventional pain course as well. Prospective observational study, following a cohort of n = 45 patients for a period of 24 months after 'indirect' ESI for radiculopathy secondary to a single-level cervical disk herniation (CDH). Arm and neck pain on the visual analog scale (VAS), health-related quality of life with the Short Form-12 (SF-12), and functional outcome with the Neck Pain and Disability (NPAD) Scale were assessed. Any additional invasive treatment after a single injection (second injection or surgery) defined treatment outcome as 'non-response'. At 24 months, n = 30 (66.7%) patients were responders and n = 15 (33.3%) were non-responders. Non-responders exited the follow-up at 1 month (n = 10), at 3 months (n = 4), and at 6 months (n = 1). No patients were injected again or operated on between the 6- and 24-month follow-up. Patients with favorable treatment response at 24 months had significantly lower VAS arm pain (p  50% short term pain reduction was not a reliable predictor of the 24-month responder status. SF-12 and NPAD scores were better among treatment responders in the long term. Patients who require a second injection or surgery after 'indirect' cervical ESI for a symptomatic CDH do so within the first 6 months. Short-term pain relief cannot reliably predict the long-term outcome.

    To determine the value of the perfusion parameters in predicting short-term tumour response to synchronous radiochemotherapy for cervical squamous carcinoma. Ninety-three patients with cervical squamous carcinoma later than stage IIB were included in this study. Perfusion CT was performed for all these patients who subsequently received the same synchronous radiochemotherapy. The patients were divided into responders and non-responders according to short-term response to treatment. Baseline perfusion parameters of the two groups were compared. The perfusion parameters that might affect treatment effect were analysed by using a multivariate multi-regression analysis. The responders group had higher baseline permeability-surface area product (PS) and blood volume (BV) values than the non-responders group (P 0.05). At multivariate multi-regression analysis, BV, PS and tumour size were significant factors in the prediction of treatment effect. Small tumours usually had high PS and BV values, and thus had a good treatment response. Perfusion CT can provide some helpful information for the prediction of the short-term effect. Synchronous radiochemotherapy may be more effective in cervical squamous carcinoma with higher baseline PS and BV. (orig.)

    We investigated different aspects of facial expression evaluation in a homogeneous cohort of 42 seizure-free patients with 5 or more years of follow-up after temporal lobectomy (TL), with the aim of further characterizing the impairment in emotion and social cognition among patients. A group of healthy subjects matched for sex, age, and education served as controls. Four tasks of facial expression evaluation were used: (a) facial expression recognition, (b) rating of the intensity of facial expression, and (c) rating of valence (pleasantness) and (d) rating of arousal induced by facial expressions. Patients had a worse performance in the recognition task for all negative emotions, while no differences in intensity ratings were found. They also reported lower arousal ratings than controls for faces showing fear, anger, disgust, and neutral expressions, as well as lower valence ratings for all facial expressions except those showing happiness. Longer epilepsy duration before TL was negatively associated with ratings of arousal and intensity and positively associated with valence ratings for fearful facial expressions. This study showed that patients who become seizure-free after TL present long-term deficits in several aspects of facial expression evaluation. Longitudinal, prospective studies are needed to evaluate if social cognition improves or declines after TL. Copyright © 2014 Elsevier Inc. All rights reserved.

  16. The value and need for long term conservation of information regarding nuclear waste repositories

    1993-12-31

    An important question in safety assessment of all repositories where toxic waste is disposed is how long should information be available to society about the repository and its content? Future societies right to knowledge must be considered and actions must already today be taken to ensure that proper information conservation, transfer and retrieval are provided. Collection of relevant information must be planned for at the research, construction and the operational phase of a repository. One of the main areas for information conservation and transfer is to mitigate future human intrusion. A system for best possible mitigation of human intrusion should with the present knowledge comprise the following parts: (a) development of planning procedures for long-term conservation of gathered information (present and future national and international archives, markers etc.); (b) continuous follow up of the state-of-the-art of information media; (c) preparations for national rules and regulations on nuclear waste information; (d) participation in international cooperation on issues concerning nuclear waste information keeping, transfer and retrieval.

  17. Assessing the value of information for long-term structural health monitoring

    Science.gov (United States)

    Pozzi, Matteo; Der Kiureghian, Armen

    2011-04-01

    In the field of Structural Health Monitoring, tests and sensing systems are intended as tools providing diagnoses, which allow the operator of the facility to develop an efficient maintenance plan or to require extraordinary measures on a structure. The effectiveness of these systems depends directly on their capability to guide towards the most optimal decision for the prevailing circumstances, avoiding mistakes and wastes of resources. Though this is well known, most studies only address the accuracy of the information gained from sensors without discussing economic criteria. Other studies evaluate these criteria separately, with only marginal or heuristic connection with the outcomes of the monitoring system. The concept of "Value of Information" (VoI) provides a rational basis to rank measuring systems according to a utility-based metric, which fully includes the decision-making process affected by the monitoring campaign. This framework allows, for example, an explicit assessment of the economical justifiability of adopting a sensor depending on its precision. In this paper we outline the framework for assessing the VoI, as applicable to the ranking of competitive measuring systems. We present the basic concepts involved, highlight issues related to monitoring of civil structures, address the problem of non-linearity of the cost-to-utility mapping, and introduce an approximate Monte Carlo approach suitable for the implementation of time-consuming predictive models.

    Malignant pleural mesothelioma (MPM) is marked by its difficult diagnosis and poor prognosis. Medical thoracoscopy (MT) is an effective and safe procedure for the diagnosis of exudative pleural effusions and many factors associated with poor prognosis of MPM. We conducted this study to investigate the value of MT for diagnosing of MPM and to identify prognostic factors for MPM patients. From July 2005 through June 2014, a total of 833 patients with undiagnosed pleural effusions underwent MT and pleural biopsies were taken. Clinical data of all patients with MPM were retrospectively analyzed, and those with complete follow-up data were analyzed for prognostic factors. Eventually, MPM was the final diagnosis in 40 patients. Diagnostic efficiency of MT for MPM was 87.5%, since diagnosis of MPM failed to be established in 5 patients during the initial MT. Median survival was 17.1 mo (95% confidence interval: 13.6-20.7 mo). MT findings of pleural adhesion and plaques were adverse prognostic factors for MPM. In addition, old age, male gender, smoking history, histological type, poor staging, no treatment, low total protein level in pleural fluid, and computed tomographic findings such as pulmonary consolidation or infiltration, mediastinal lymphopathy, pulmonary mass or nodules, and pleural nodularity were also poor prognostic factors for MPM. MT is safe with a high positive rate in the diagnosis of MPM, and pleural adhesion and plaques seen under MT may be the adverse prognostic factors for MPM. Multiple clinical characteristics can affect the survival of MPM patients.

    In this paper, we discuss an initial-boundary value problem (IBVP) for the multi-term time-fractional diffusion equation with x-dependent coefficients. By means of the Mittag-Leffler functions and the eigenfunction expansion, we reduce the IBVP to an equivalent integral equation to show the unique existence and the analyticity of the solution for the equation. Especially, in the case where all the coefficients of the time-fractional derivatives are non-negative, by the Laplace and inversion L...

    This study sought to evaluate the long-term prognostic value of coronary computed tomography angiography (CTA) in asymptomatic patients with type 2 diabetes mellitus. There are limited data on the long-term prognostic impact of coronary CTA in asymptomatic patients with type 2 diabetes mellitus. This study analyzed clinical outcomes of 591 consecutive asymptomatic patients with type 2 diabetes mellitus who underwent coronary CTA (mean age 62.2 ± 8.3 years and 352 men [59.6%]). A cardiac event was defined as a composite of cardiac death, nonfatal myocardial infarction, unstable angina requiring hospitalization, or late coronary revascularization. Patients were categorized into 3 groups according to severity of coronary artery disease (CAD) on coronary CTA: normal coronary arteries, nonobstructive CAD (28.4%) had normal coronary arteries, whereas 236 (39.9%) patients had nonobstructive CAD and 187 (31.6%) had obstructive CAD. During the follow-up period (median 5.3 years [interquartile range: 4.7 to 5.8 years]), 37 cardiac events occurred in 29 patents: 10 cardiac deaths, 2 nonfatal myocardial infarctions, 8 cases of unstable angina, and 17 late coronary revascularizations. The 6-year event-free survival rates were 99.3 ± 0.7% in patients with normal coronary arteries, 96.7 ± 1.2% in patients with nonobstructive CAD, and 86.2 ± 3.0% in patients with obstructive CAD (log-rank p type 2 diabetes mellitus with normal coronary arteries or nonobstructive CAD on coronary CTA show excellent clinical outcomes over a follow-up period of more than 5 years, whereas prognosis is worse in patients with obstructive CAD. These findings suggest long-term prognostic value of coronary CTA for asymptomatic type 2 diabetes mellitus. Copyright © 2016 American College of Cardiology Foundation. Published by Elsevier Inc.

    Full Text Available Tendo em vista a importância do Value at Risk (VaR como medida de risco para instituições financeiras e agências de risco, o presente estudo avaliou se o modelo ARLS é mais preciso no cálculo do VaR de longo prazo que os modelos tradicionais, dada sua maior adequação para a previsão da volatilidade. Considerando a utilização do VaR pelos agentes de mercado como medida de risco para o gerenciamento de portfólios é importante sua adequada mensuração. A partir de dados diários dos mercados de ações e cambial dos BRICS (Brasil, Rússia, Índia, China e África do Sul foram calculadas as volatilidades futuras para 15 dias, 1 mês e 3 meses. Em seguida, calculou-se as medidas tradicionais de avaliação da precisão do VaR. Os resultados sugerem a superioridade do modelo ARLS para a previsão da volatilidade cambial, capaz de prever corretamente o número de violações em 33% dos casos, enquanto os modelos tradicionais não obtiveram um bom desempenho. Com relação ao mercado acionário, os modelos GARCH e ARLS apresentaram desempenho similar. O modelo GARCH é superior considerando a perda média quadrática. Esses resultados apontam para a escolha do modelo ARLS no cálculo do VaR de portfólios cambiais devido a maior precisão alcançada. Ajuda assim os agentes de mercado a melhor gerirem o risco de suas carteiras. Em relação ao mercado acionário, em função do desempenho similar dos modelos GARCH e ARLS, o modelo GARCH é o mais indicado devido a sua maior simplicidade e fácil implementação computacional. Having in mind the importance of Value at Risk (VaR as a risk measure for financial institutions and rating agencies, this study evaluated whether the ARLS model is more accurate in the calculation of the long term VaR than the traditional models, considering it is more appropriate for predicting the long-term volatility. Due to the fact that VaR s being used for market players as a measure of risk for the portfolio

  4. Long-term risks of metal contaminants in drinking water: a critical appraisal of guideline values for arsenic and vanadium

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Metal contaminants in drinking water represent a relevant health issue in several areas of the world. In Italy, because of the geological features of the territory, high arsenic and vanadium are frequently reported in ground waters in concentrations above current guideline values. The implications for public health of the presence of contaminants above their legal limit are directly related to the biological basis of the guideline value. In the case of arsenic there are still major uncertainties in the mechanism of carcinogenesis which prevent a precise evaluation of long-term risks. Thus, the guideline value endorsed in the European Community (10 µg/L has to be considered as a pragmatic tool rather than a quality objective, bearing in mind that "every effort should be made to keep concentrations as low as reasonably possible" (WHO, 2011. A reverse situation holds for vanadium, for which a strict national limit (50 µg/L was previously proposed in consideration of data gaps, and for which new evidence indicated a less stringent health-based limit.

  5. Ecocultural Attributes: Evaluating Ecological Degradation in Terms of Ecological Goods and Services Versus Subsistence and Tribal Values

    It is becoming increasingly clear that scientists, managers, lawyers, public policymakers, and the public must decide how to value what is provided by, and is a consequence of, natural resources. While “Western” scientists have clear definitions for the goods and services that ecosystems provide, we contend that these categories do not encompass the full totality of the values provided by natural resources. Partly the confusion results from a limited view of natural resources derived from the need to monetize the value of ecosystems and their component parts. Partly it derives from the “Western” way of separating natural resources from cultural resources or values, and partly it derives from the false dichotomy of assuming that ecosystems are natural, and anything constructed by man is not natural. In this article, we explore the previous assumptions, and suggest that because cultural resources often derive from, and indeed require, intact and unspoiled natural ecosystems or settings, that these values are rightly part of natural resources. The distinction is not trivial because of the current emphasis on cleaning up chemically and radiologically contaminated sites, on restoration of damaged ecosystems, on natural resource damage assessments, and on long-term stewardship goals. All of these processes depend upon defining natural resources appropriately. Several laws, regulations, and protocols depend upon natural resource trustees to protect natural resources on trust lands, which could lead to the circular definition that natural resources are those resources that the trustees feel they are responsible for. Where subsistence or tribal peoples are involved, the definition of natural resources should be broadened to include those ecocultural attributes that are dependent upon, and have incorporated, natural resources. For example, a traditional hunting and fishing ground is less valued by subsistence peoples if it is despoiled by contamination or physical

    Genome-wide association studies allow us to understand the genetics of complex diseases. Human metabolism provides information about the disease-causing mechanisms, so it is usual to investigate the associations between genetic variants and metabolite levels. However, only considering genetic variants and their effects on one trait ignores the possible interplay between different "omics" layers. Existing tools only consider single-nucleotide polymorphism (SNP)-SNP interactions, and no practical tool is available for large-scale investigations of the interactions between pairs of arbitrary quantitative variables. We developed an R package called pulver to compute p-values for the interaction term in a very large number of linear regression models. Comparisons based on simulated data showed that pulver is much faster than the existing tools. This is achieved by using the correlation coefficient to test the null-hypothesis, which avoids the costly computation of inversions. Additional tricks are a rearrangement of the order, when iterating through the different "omics" layers, and implementing this algorithm in the fast programming language C++. Furthermore, we applied our algorithm to data from the German KORA study to investigate a real-world problem involving the interplay among DNA methylation, genetic variants, and metabolite levels. The pulver package is a convenient and rapid tool for screening huge numbers of linear regression models for significant interaction terms in arbitrary pairs of quantitative variables. pulver is written in R and C++, and can be downloaded freely from CRAN at https://cran.r-project.org/web/packages/pulver/ .

    Communication in the intensive care unit (ICU) is an important component of quality ICU care. In this report, we evaluate the long-term effects of a quality improvement (QI) initiative, based on the VALUE communication strategy, designed to improve communication with family members of critically ill patients. We implemented a multifaceted intervention to improve communication in the ICU and measured processes of care. Quality improvement components included posted VALUE placards, templated progress note inclusive of communication documentation, and a daily rounding checklist prompt. We evaluated care for all patients cared for by the intensivists during three separate 3 week periods, pre, post, and 3 years following the initial intervention. Care delivery was assessed in 38 patients and their families in the pre-intervention sample, 27 in the post-intervention period, and 41 in follow-up. Process measures of communication showed improvement across the evaluation periods, for example, daily updates increased from pre 62% to post 76% to current 84% of opportunities. Our evaluation of this quality improvement project suggests persistence and continued improvements in the delivery of measured aspects of ICU family communication. Maintenance with point-of-care-tools may account for some of the persistence and continued improvements. Copyright © 2014 Elsevier Inc. All rights reserved.

    Aim: To determine the long-term prognostic value of SPECT myocardial perfusion imaging (MPI) for the occurrence of cardiovascular events in diabetic patients. Patients, methods: SPECT MPI of 210 consecutive Caucasian diabetic patients were analysed using Kaplan-Meier event-free survival curve and independent predictors were determined by Cox multivariate analyses. Results: Follow-up was complete in 200 (95%) patients with a median period of 3.0 years (0.8-5.0). The population was composed of 114 (57%) men, age 65 ± 10 years, 181 (90.5%) type 2 diabetes mellitus, 50 (25%) with a history of coronary artery disease (CAD) and 98 (49%) presenting chest pain prior to MPI. The prevalence of abnormal MPI was 58%. Patients with a normal MPI had neither cardiac death, nor myocardial infarction, independently of a history of coronary artery disease or chest pain. Among the independent predictors of cardiac death and myocardial infarction, the strongest was abnormal MPI (p 5-fold increase in cardiovascular events. This emphasizes the value of SPECT MPI in predicting and risk-stratifying cardiovascular events in diabetic patients. (orig.)

    On behalf of the Ministry of Environment the Austrian Academy of Science published guideline values for nitrogen dioxide in 1988. The scientific database concentrated on short-term effects of NO{sub 2} at that time. After checking the current literature it was clear that new data especially for long-term effects of NO{sub 2} were available which should lead to a limitation of an annual average. Two Austrian studies on children from Linz (capital of Upper Austria) showed that high long-term concentrations of NO{sub 2} were negatively associated with the flow parameters of terminal airways in spirometry (MEF{sub 25} and MEF{sub 50}) on a significant level. In addition the children showed an improvement in growth-dependent increase of lung function parameters when long-term NO{sub 2}-concentrations in the ambient air could be decreased by more than 40 {mu}g/m{sup 3}. The most pronounced benefit could be seen when the ambient level of NO{sub 2} decreased during periods of accelerated growth. Based on these and other results summarized in this review, the Austrian Academy of Science recommended an annual average of 30 {mu}g/m{sup 3} for NO{sub 2} in the ambient air not to be exceeded for health protection.

    Building on an approach applied to cardiovascular and cancer research, we estimated the economic returns from United Kingdom public- and charitable-funded musculoskeletal disease (MSD) research that arise from the net value of the improved health outcomes in the United Kingdom. To calculate the economic returns from MSD-related research in the United Kingdom, we estimated (1) the public and charitable expenditure on MSD-related research in the United Kingdom between 1970 and 2013; (2) the net monetary benefit (NMB), derived from the health benefit in quality adjusted life years (QALYs) valued in monetary terms (using a base-case value of a QALY of £25,000) minus the cost of delivering that benefit, for a prioritised list of interventions from 1994 to 2013; (3) the proportion of NMB attributable to United Kingdom research; and (4) the elapsed time between research funding and health gain. The data collected from these four key elements were used to estimate the internal rate of return (IRR) from MSD-related research investments on health benefits. We analysed the uncertainties in the IRR estimate using a one-way sensitivity analysis. Expressed in 2013 prices, total expenditure on MSD-related research from 1970 to 2013 was £3.5 billion, and for the period used to estimate the rate of return, 1978-1997, was £1.4 billion. Over the period 1994-2013 the key interventions analysed produced 871,000 QALYs with a NMB of £16 billion, allowing for the net NHS costs resulting from them and valuing a QALY at £25,000. The proportion of benefit attributable to United Kingdom research was 30% and the elapsed time between funding and impact of MSD treatments was 16 years. Our best estimate of the IRR from MSD-related research was 7%, which is similar to the 9% for CVD and 10% for cancer research. Our estimate of the IRR from the net health gain to public and charitable funding of MSD-related research in the United Kingdom is substantial, and justifies the research investments

    Missing values are commonly encountered on the Mini Mental State Examination (MMSE), particularly when administered to frail older people. This presents challenges for MMSE scoring in research settings. We sought to describe missingness in MMSEs administered in long-term-care facilities (LTCF) and to compare and contrast approaches to dealing with missing items. As part of the Care and Construction project in Nova Scotia, Canada, LTCF residents completed an MMSE. Different methods of dealing with missing values (e.g., use of raw scores, raw scores/number of items attempted, scale-level multiple imputation [MI], and blended approaches) are compared to item-level MI. The MMSE was administered to 320 residents living in 23 LTCF. The sample was predominately female (73%), and 38% of participants were aged >85 years. At least one item was missing from 122 (38.2%) of the MMSEs. Data were not Missing Completely at Random (MCAR), χ 2 (1110) = 1,351, p < 0.001. Using raw scores for those missing <6 items in combination with scale-level MI resulted in the regression coefficients and standard errors closest to item-level MI. Patterns of missing items often suggest systematic problems, such as trouble with manual dexterity, literacy, or visual impairment. While these observations may be relatively easy to take into account in clinical settings, non-random missingness presents challenges for research and must be considered in statistical analyses. We present suggestions for dealing with missing MMSE data based on the extent of missingness and the goal of analyses. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V.

The prevalence of abnormal MPI was 58%. Patients with a normal MPI had neither cardiac death, nor myocardial infarction, independently of a history of coronary artery disease or chest pain. Among the independent predictors of cardiac death and myocardial infarction, the strongest was abnormal MPI (p < 0.0001), followed by history of CAD (Hazard Ratio (HR) = 15.9; p = 0.0001), diabetic retinopathy (HR = 10.0; p = 0.001) and inability to exercise (HR = 7.7; p = 0.02). Patients with normal MPI had a low revascularisation rate of 2.4% during the follow-up period. Compared to normal MPI, cardiovascular events increased 5.2 fold for reversible defects, 8.5 fold for fixed defects and 20.1 fold for the association of both defects. Conclusion: Diabetic patients with normal MPI had on excellent prognosis independently of history of CAD. On the opposite, an abnormal MPI led to a > 5-fold increase in cardiovascular events. This emphasizes the value of SPECT MPI in predicting and risk-stratifying cardiovascular events in diabetic patients. (orig.)

    term experiments to implement novel observational systems. Through active collaboration with the teams in charge of the experiments, users will take advantage of the site characterization, historical data, monitoring setup and access to different treatments experimental field with differentiated properties induced by repeated treatment. • Access to soil and vegetation samples collected at different dates that may be reanalyzed a posteriori to take profit of technological progress. • Delivery of reference data on ecosystems subjected to a gradient of anthropogenic and climatic pressures. The research infrastructure level is appropriate to implement a harmonization policy for the measurement and observation protocols. Moreover it offers the possibility of developing an ambitious strategy in integrating data and models. These can contribute to the experimental process for protocol design or data quality control. Moreover, they offer an efficient way for promoting data reuse thus giving a strong added value to the existing data bases. Therefore, building interoperability between models and experimental platform data bases is an important objective to improve the quality of experimental infrastructure and provide users with seamless and integrated information systems. We present how this is operated in AnaEE-France with different tasks as the development of a controlled vocabulary, tools to annotate data and model variables with metadata based on ontologies and the development of webservice to harvest data from the data base to the modelling platform environment. Finally some examples of key results taking profit of the range of experiments are provided.

    To determine the frequency of different disorders requiring warfarin therapy and to see the target INR and warfarin dose requirement in Pakistani population. Study Design:Descriptive study. Setting and Duration of Study: The study was carried out at Armed Forces Institut e of Cardiology (AFIC) Rawalpindi, Military Hospital Rawalpindi and National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan from October 2010 to March 2012. Patients and Methods: Stable patients taking warfarin therapy were recruited after detailed medical history, physical examination and laboratory tests. The demographic and clinical data of individuals were entered in a pre-structured proforma. Patients suffering from hepatic and renal disease, any co-morbid disease or taking any concurrent medication or diet which would have affected warfarin therapy, were excluded. Data was analyzed using PSS version 20.0. Results: A total of 607 stable patients fulfilling the eligibility criteria, participated in the study. There were 297 (48.9%) male and 310 (51.1%) female patients. The mean age was 37.93 +- 12.23 years (range 18-65 years). The most common indication for warfarin therapy was valvular heart diseases (93.4%) followed by atrial fibrillation (2.3%) whereas other indications for warfarin use are less commonly seen in our study population. Patients had mean international normalized ratio (INR) value of 2.3 +9- 0.8 (range 1.5-3.5). Mean daily dose of warfarin calculated in 607 patients was 5.62 and 1.98 mg with the range of 0.36-15 g whereas mean weekly dose was 39.36 +- 13.8 mg with the range of 2.5-105 mg. Conclusion: In Pakistani population the most common indications for warfarin use are valvular heart diseases followed by atrial fibrillation. The mean INR values were within recommended range of 2-3. The mean daily dose observed in long-term therapy is comparable to the empirical dose of 5 mg routinely started in clinical practice. (author)

    The objective was to evaluate the prognostic value of exercise myocardial perfusion scintigraphy (MPS) in patients who underwent coronary artery bypass grafting (CABG). A retrospective, one-center study of 361 patients with multivessel coronary artery disease was carried out. All the patients underwent MPS after CABG due to worsened health status. MPS was performed at 4.5 years standard deviation (SD: 0.2), based on symptoms. MPS was carried out using Tc-99m methoxy isobutyl isonitrile and following a 1-day protocol (stress-rest). The end points were analyzed at 6.5 years (SD: 3.3) after MPS, on the average. SPSS software for Windows, version 13.0. The t-test or the χ 2 -test was used. Survival times were calculated. A multivariate Cox proportional hazards model was developed. During the follow-up, death occurred in 54 patients, and 37 patients experienced major adverse cardiovascular events (MACE). In the multivariate analysis, advanced age hazard ratio (HR: 1.45; 95% confidence interval [CI]: 1.4–2.02; P = 0.027), previous myocardial infarction (HR: 3.17; 95% CI: 1.22–8.2; P = 0.018), left ventricular ejection fraction of <40% (HR: 2.16; 95% CI: 1.2–3.89; P = 0.01), and the summed stress score (SSS) of ≥4 (HR: 1.87; 95% CI: 1.02–3.41; P = 0.04) were independent predictors of all-cause death. The summed difference score (SDS) was the only independent predictor of MACE (HR: 1.26; 95% CI: 1.06–1.48; P = 0.034). The parameters of MPS were found to have prognostic value in the long-term period after CABG. Advanced age, previous myocardial infarction, decreased left ventricular ejection fraction, and the abnormal SSS were associated with an increased risk of all-cause death. The SDS was found to be the only significant risk factor for MACE

    Full Text Available Background: Literature on prognosis of transient ischemic attack (TIA in Chinese is scarce. The short-term prognosis of TIA and the predictive value of the ABCD2 score in Hong Kong Chinese patients attending the emergency department (ED were studied to provide reference for TIA patient management in our ED. Methods: A cohort of TIA patients admitted through the ED to 13 acute public hospitals in 2006 was recruited through the centralized electronic database by the Hong Kong Hospital Authority (HA. All inpatients were e-coded by the HA according to the International Classification of Diseases, Ninth Revision (ICD9. Electronic records and hard copies were studied up to 90 days after a TIA. The stroke risk of a separate TIA cohort diagnosed by the ED was compared. Results: In the 1,000 recruited patients, the stroke risk after a TIA at days 2, 7, 30, and 90 was 0.2, 1.4, 2.9, and 4.4%, respectively. Antiplatelet agents were prescribed in 89%, warfarin in 6.9%, statin in 28.6%, antihypertensives in 39.3%, and antidiabetics in 11.9% of patients after hospitalization. Before the index TIA, the prescribed medications were 27.6, 3.7, 11.3, 27.1, and 9.7%, respectively. The accuracy of the ABCD2 score in predicting stroke risk was 0.607 at 7 days, 0.607 at 30 days, and 0.574 at 90 days. At 30 days, the p for trend across ABCD2 score levels was 0.038 (OR for every score point = 1.36, p = 0.040. Diabetes mellitus, previous stroke and carotid bruit were associated with stroke within 90 days (p = 0.038, 0.045, 0.030, respectively. A total of 45.4% of CTs of the brain showed lacunar infarcts or small vessel disease. There was an increased stroke risk at 90 days in patients with old or new infarcts on CT or MRI. Patients with carotid stenosis ≥70% had an increased stroke risk within 30 (OR = 6.335, p = 0.013 and 90 days (OR = 3.623, p = 0.050. Stroke risks at days 2, 7, 30, and 90 in the 289 TIA patients diagnosed by the ED were 0.35, 2.4, 5.2, and 6

    Full Text Available Available on the commercial market are a number of algorithms that enable assigning to pixels of a monochrome digital image suitable colors according to a strictly defined schedule. These algorithms have been recently used by professional film studios involved in the coloring of archival productions. This article provides an overview on the functionality of coloring algorithms in terms of their use to improve the interpretation quality of historical, black - and - white aerial photographs. The analysis covered intuitive (Recolored programs, as well as more advanced (Adobe After Effect, DaVinci Resolve programs. The use of their full functionality was limited by the too large information capacity of aerial photograph images. Black - and - white historical aerial photographs, which interpretation quality in many cases does not meet the criteria posed on photogrammetric developments, require an increase of their readability. The solution in this regard may be the process of coloring images. The authors of this article conducted studies aimed to determine to what extent the tested coloring algorithms enable an automatic detection of land cover elements on historical aerial photographs and provide color close to the natural. Used in the studies were archival black - and - white aerial photographs of the western part of Warsaw district made available by the Main Centre of Geodetic and Cartographic Documentation , the selection of which was associated with the presence in this area of various elements of land cover, such as water, forests, crops, exposed soils and also anthropogenic objects. In the analysis of different algorithms are included: format and size of the image, degree of automation of the process, degree of compliance of the result and processing time. The accuracy of the coloring process was different for each class of objects mapped on the photograph. The main limitation of the coloring process created shadows of anthropogenic objects

    Full Text Available ObjectiveTo evaluate the clinical value of five-stage prognostic system in predicting the short-term outcome of patients with liver cirrhosis, and to compare it with the Child-Turcotte-Pugh (CTP and Model of End-Stage Liver Disease (MELD scores. MethodsTwo hundred and one hospitalized patients with liver cirrhosis in the Department of Gastroenterology in the First Affiliated Hospital of Anhui Medical University from January 2011 to January 2014 were enrolled in the study and followed up for at least six months. Patients were classified accorded to the five-stage prognostic system, and the mortality rate in each stage was measured. The receiver operating characteristic (ROC curve and the area under the ROC curve (AUC were used to assess the accuracy of the five-stage prognostic system in predicting the short-term death risk of cirrhotic patients, which was then compared with the CTP and MELD scores. Categorical data were analyzed by chi-square test. Comparison of AUC was made by normal distribution Z test. Spearman′s correlation analysis was used to investigate the correlation of the five-stage prognostic system with the CTP and MELD scores. ResultsThe study used the admission time as the starting point and the death of patients or study termination time as the endpoint. Among the 201 patients, 50 (24.9% died within six months. Based on the five-stage prognostic system, the mortality rates for stages 1 to 5 were 0(0/11, 0(0/18, 4.2%(2/48, 16.3% (7/43, and 50.6%(41/81, respectively. In patients with decompensated cirrhosis (stages 3, 4, and 5, the mortality increased with stage, and the differences in mortality between patients in stages 3 and 4, 3 and 5, and 4 and 5 were all significant (χ2=3.89, 35.33, and 13.96, respectively; P=0.049, 0.000, and 0.049, respectively.

    Full Text Available Psychological research shows that subjective task value, a basic component of expectancyvalue theory as outlined by Eccles, predicts task choice (e.g., going to graduate school. However, Eccles’ approach has not been used to investigate adult learning so far. Therefore, the present study investigated a specific form of subjective task value and task choice, namely adults’ subjective task value of participation in education. Based on expectancy-value theory, qualitative content analyses of 16 interviews with adult learners (aged between 21 and 67 from varying age groups and educational backgrounds show a differentiation of positive value according to points of reference and a revised conceptualisation of cost as an independent component of subjective task value with four subcomponents. Apparently people estimate positive value and cost separately at first and only later weigh these components against each other to arrive at an overall evaluation of subjective task value, which, in turn, predicts participation in education. Moreover, results suggest a distinction between anticipated subjective task value prior to participation and subjective task value based on experience (i.e., in hindsight. Benefits of using expectancy-value theory for future research on adults’ participation in education are discussed.

  2. Outcomes of long-term outpatient tinnitus-coping therapy: psychometric changes and value of tinnitus-control instruments.

    Increasing tinnitus compliance and coping are desirable aims of successful treatment in chronic tinnitus. However, application of established procedures such as tinnitus retraining therapy (TRT) is often relatively short. In addition, the value of tinnitus control instruments (TCI) is questionable, especially for minor severity levels of tinnitus, and the comparability of treatment results is low. To evaluate long-term changes of tinnitus-related distress, defined psychometric data were collected in patients with compensated tinnitus (cT) or decompensated tinnitus (dT) during a standardized 2-yr outpatient tinnitus-coping therapy (TCT). In a prospective clinical investigation, the data of 70 tinnitus patients were recorded at the beginning and at 6-mo intervals, with a final investigation after 24 mo. The first group consisted of 40 patients with cT and dT who were randomly assigned to a treatment group and a waiting-list control group. After a period of 12 mo without treatment, the control group was treated similarly. The tinnitus questionnaire (TQ) of Goebel and Hiller, visual analog scales (VAS), and a severity questionnaire for tinnitus-associated complaints were used as psychodiagnostic instruments. Therapy components consisted of counseling, fitting patients with TCIs (TCI provision), auditory and relaxation training, and psychosomatic care if necessary. A second group of 30 patients with cT receiving TCT without TCI devices was investigated to evaluate the additive efficacy of TCI in cT. The initial TQ score did not differ between the treatment group and the waiting-list control group. After 12 mo, the control group did not show any significant changes, but the treatment group had improved significantly. During TCT, the combined data of both groups showed a statistically significant decrease of the TQ score in dT (59.1 to 34.8) and cT (32.8 to 24.0). These changes were especially reflected by the subscales of cognitive and emotional distress and also by the

    Free-flowing river segments provide refuges for many imperiled aquatic biota that have been extirpated elsewhere in their native ranges. These biodiversity refuges are also foci of conservation concerns because species persisting within isolated habitat fragments may be particularly vulnerable to local environmental change. We have analyzed long-term (14- and 20-y) survey data to assess evidence of fish species declines in two southeastern U.S. rivers where managers and stakeholders have identified potentially detrimental impacts of current and future land uses. The Conasauga River (Georgia and Tennessee) and the Etowah River (Georgia) form free-flowing headwaters of the extensively dammed Coosa River system. These rivers are valued in part because they harbor multiple species of conservation concern, including three federally endangered and two federally threatened fishes. We used data sets comprising annual surveys for fish species at multiple, fixed sites located at river shoals to analyze occupancy dynamics and temporal changes in species richness. Our analyses incorporated repeated site-specific surveys in some years to estimate and account for incomplete species detection, and test for species-specific (rarity, mainstem-restriction) and year-specific (elevated frequencies of low- or high-flow days) covariates on occupancy dynamics. In the Conasauga River, analysis of 26 species at 13 sites showed evidence of temporal declines in colonization rates for nearly all taxa, accompanied by declining species richness. Four taxa (including one federally endangered species) had reduced occupancy across the Conasauga study sites, with three of these taxa apparently absent for at least the last 5 y of the study. In contrast, a similar fauna of 28 taxa at 10 sites in the Etowah River showed no trends in species persistence, colonization, or occupancy. None of the tested covariates showed strong effects on persistence or colonization rates in either river. Previous studies

    Full Text Available This paper will focus on the study and identifying various threshold values for two commonly used edge detection techniques, which are Sobel and Canny Edge detection. The idea is to determine which values are apt in giving accurate results in identifying a particular leukemic cell. In addition, evaluating suitability of edge detectors are also essential as feature extraction of the cell depends greatly on image segmentation (edge detection. Firstly, an image of M7 subtype of Acute Myelocytic Leukemia (AML is chosen due to its diagnosing which were found lacking. Next, for an enhancement in image quality, noise filters are applied. Hence, by comparing images with no filter, median and average filter, useful information can be acquired. Each threshold value is fixed with value 0, 0.25 and 0.5. From the investigation found, without any filter, Canny with a threshold value of 0.5 yields the best result.

    A more practice approach for the determination of monetary values of the unit collective dose for intervention against long-term exposure following a nuclear accident was proposed. In addition, the monetary values of the unit collective dose estimated from the proposed approach were compared with those estimated from the previous model, which are derived from assumptions of routine exposure and the same values are applied in a nuclear accident without modification, using Korea economic data. The monetary values based on the proposed approach showed a distinct difference depending on inequity in the distribution of individual doses. The discounting rate was also an important factor in determination of monetary values of the unit collective dose

    Most areas in Indonesia consist of clay soils with high plasticity so that to meet technical requirements the soil needs improvement, which is known as soil stabilization.There are three ways of soil stabilization process, i.e. mechanical, physical and chemical. In this study, chemical stabilization was performed, that was by adding stabilizing agents to the soil. The stabilizing agent used was the ash of Mount Sinabung. Since 2010 until now, Sinabung Mountain is still experiencing eruption that produces a lot of volcanic ash and it inconveniences the environment. So, it is expected that this research will be able to optimize the utilization of Sinabung ash. The purpose of this study was to investigate the effect of the addition of Mount Sinabung ash to CBR (California Bearing Ratio) value, to determine the effect of the curing time of one day and fourteen days mixture on the CBR value, and to find the mixed content with effective curing time to produce the largest CBR value. Based on this study, the soil type CL (Clay - Low Plasticity) was obtained, based on the classification of USCS (Unified Soil Classification System) and categorized as A-6 (6) based on the classification of AASHTO (American Association of State Highway and Transportation officials) with the most effective mixed stabilizer material which was the variation of 10% Mount Sinabung ash with fourteen days of curing time. The CBR value resulted from the mixture of 10% Sinabung ash that was cured within fourteen days was 8.95%. By the increase of the content of the Sinabung ash, the CBR value always improved to the level of 10%, Sinabung ash then decreased and became constant at the mixture of higher volcanic ash mixture but remained above the CBR value of the original soil.

At baseline, the cross-sectional area (CSA of the median nerve was measured with ultrasound at 4 levels on the forearm and wrist. PD signals were graded semi-quantitatively (0-3. Clinical outcomes were evaluated at each visit with the Boston Questionnaire (BQ and the DASH Questionnaire, as well as visual analogue scales for the patient's assessment of pain (painVAS and physician's global assessment (physVAS. The predictive values of baseline CSA and PD for clinical outcomes were determined with multivariate logistic regression models.Short-term and long-term follow-up data were available for 111 (82.2% and 105 (77.8% patients, respectively. There was a final diagnosis of CTS in 84 patients (125 wrists. Regression analysis revealed that the CSA, measured at the carpal tunnel inlet, predicted short-term clinical improvement according to BQ in CTS patients undergoing carpal tunnel surgery (OR 1.8, p = 0.05, but not in patients treated conservatively. Neither CSA nor PD assessments predicted short-term improvement of painVAS, physVAS or DASH, nor was any of the ultrasound parameters useful for the prediction of long-term clinical outcomes.Ultrasound assessment of the median nerve at the carpal tunnel inlet may predict short-term clinical improvement in CTS patients undergoing carpal tunnel release, but long-term outcomes are unrelated to ultrasound findings.

    Full Text Available Abstract Innovations seem crucial for contemporary enterprises willing to achieve the objective of increasing firm’s value. The aim of this paper is to examine, both conceptually and empirically, the relationship between innovations and tourism enterprises’ market value. Tourism sector was taken into consideration in order to fulfill the existing research gap. This focused paper was based on relevant market data. Event study and calendar time portfolio approaches were chosen to test investors’ responses to innovation announcements. Six tourism companies listed on the Main Market of Warsaw Stock Exchange were examined within the six years research period and 34 innovation announcements were identified. Polish Press Agency database and Warsaw Stock Exchange databases were used to collect data. Results indicate that innovations affected positively investors’ valuation of tourism enterprises. The average event day market value change equaled 0.63% and differed considerably from the one-year one of 3.02% meaning that investors adjust their initial reaction over time. Initially investors reacted mostly to marketing, distributional and external relations innovations while within one-year period they attributed the most value to marketing and external relations ones.

  2. Men still value physical attractiveness in a long-term mate more than women: rejoinder to Eastwick, Neff, Finkel, Luchies, and Hunt (2014).

    Sexual selection theory and parental investment theory suggest that partner physical attractiveness should more strongly affect men's relationship outcomes than women's relationship outcomes. Nevertheless, the contextual nature of this prediction makes serious methodological demands on studies designed to evaluate it. Given these theories suggest that men value observable aspects of partner attractiveness more than women do only in the context of long-term and reproductively viable relationships, they require that studies testing this sex difference involve (a) participants in long-term relationships, (b) women of child-bearing age, and (c) measures of physical attractiveness that assess observable aspects of appearance. In our original article (Meltzer, McNulty, Jackson, & Karney, 2014), we applied 7 methodological standards that allowed us to meet these 3 criteria and demonstrated that partner physical attractiveness is more strongly associated with men's long-term relationship satisfaction than women's long-term relationship satisfaction. Eastwick, Neff, Finkel, Luchies, and Hunt (2014), in contrast, described an unfocused meta-analysis, a refocused meta-analysis, and new data that all failed to meet these criteria and, not surprisingly, failed to demonstrate such a sex difference. We continue to believe that men value physical attractiveness more than women do, that such preferences have implications for their evaluations of long-term relationships, and that studies properly calibrated to detect such differences will do so.

Amendments have been made to the Employment Equity Act 55 of 1998 (EEA to include a specific provision to regulate equal pay claims in the form of section 6(4-(5 of the EEA. The amendments were made in terms of the Employment Equity Amendment Act 47 of 2013, which came into effect on 1 August 2014 by presidential proclamation. Prior to section 6(4, the EEA did not contain a specific provision regulating equal pay claims. Claims could be brought in terms of section 6(1 of the EEA, which prohibits unfair discrimination on a number of grounds. The recent amendments to the EEA in the form of section 6(4-(5 (including the Employment Equity Regulations and the Code of Good Practice on Equal Pay for Work of Equal Value in respect of equal pay claims is a response to the ILO's criticism of South Africa's failure to include specific equal pay provisions in the EEA. Section 6(4 of the EEA provides for three causes of action in respect of equal pay. They are as follows: (a equal pay for the same work; (b equal pay for substantially the same work; and (c equal pay for work of equal value. The first two causes of action are not difficult to understand as opposed to the third cause of action, which is complex. The ILO has recognised the complexity of the third cause of action, "equal pay for work of equal value". In Mangena v Fila South Africa 2009 12 BLLR 1224 (LC, the Labour Court remarked in the context of an equal pay for work of equal value claim that it does not have expertise in job grading and in the allocation of value to particular occupations. This article will deal with the third cause of action only, "equal pay for work of equal value". The

    Abdominal fat tissue aspiration was used in 22 long-term hemodialysis patients (5-17 years). Fourteen of these patients had carpal tunnel syndrome and amyloid deposits of beta 2-microglobulin in the synovium. One patient had a spontaneous rupture of the spleen with amyloid deposits in spleen vessels. Seven other patients presented carpal tunnel syndrome and/or articular pains, and radiological lytic lesions in bone, strongly suggesting an amyloid origin. As a control group, in 22 patients with biopsy-proven amyloidosis, abdominal fat tissue aspirates were performed and were studied under the same conditions: by light microscopy these tissues were stained with Congo red and examined with a polarizing microscope; these specimens were also studied by electron microscopy. In all hemodialyzed patients, no amyloid deposit was present in fat tissue with Congo red staining and by electron microscopy. On the contrary, amyloid was observed in 17 of 22 cases in other types of amyloidosis. It seems that this method which has been proved to be simple and sensitive for the diagnosis of systemic amyloidosis is not a good marker for the presence of amyloid in long-term hemodialysis patients.

  5. Long-term energy services security: What is it and how can it be measured and valued?

    The paper reviews some recent approaches towards measuring the extent of long-term energy security and security externality valuation. It starts out to discuss the contextual connotations of notions of 'energy security' in medium to long-term time frames and reviews some indicators that have been proposed to quantify it. Special attention is paid to two of these approaches, which the authors helped to develop, i.e. diversity-based indices and the Supply/Demand Index. The paper takes issue with conventional welfare economic approaches that neglect: (i) the scope on the demand side for raising security and (ii) negative feedback mechanisms of socio-political impacts of international rent transfers in fossil fuels exporting countries. The concept of energy services security is proposed with a demand-side focus. This enables application of an integrated approach to gauge the resilience of a society to meet the needs of its population for energy services over longer timescales ahead from various interrelated perspectives. Propositions are made on the attribution of security externalities to the use of fossil fuels, policies, and suggestions for further improvements of measures for energy services security.

    Several businesses and industries rely on rainfall forecasts to support their day-to-day operations. To deal with the uncertainty associated with rainfall forecast, some meteorological organisations have developed products, such as ensemble forecasts. However, due to the intensive computational requirements of ensemble forecasts, the spatial resolution remains coarse. For example, Environment and Climate Change Canada's (ECCC) Global Ensemble Prediction System (GEPS) data is freely available on a 1-degree grid (about 100 km), while those of the so-called High Resolution Deterministic Prediction System (HRDPS) are available on a 2.5-km grid (about 40 times finer). Potential users are then left with the option of using either a high-resolution rainfall forecast without uncertainty estimation and/or an ensemble with a spectrum of plausible rainfall values, but at a coarser spatial scale. The objective of this study was to evaluate the added value of coupling the Gibbs Sampling Disaggregation Model (GSDM) with ECCC products to provide accurate, precise and consistent rainfall estimates at a fine spatial resolution (10-km) within a forecast framework (6-h). For 30, 6-h, rainfall events occurring within a 40,000-km2 area (Québec, Canada), results show that, using 100-km aggregated reference rainfall depths as input, statistics of the rainfall fields generated by GSDM were close to those of the 10-km reference field. However, in forecast mode, GSDM outcomes inherit of the ECCC forecast biases, resulting in a poor performance when GEPS data were used as input, mainly due to the inherent rainfall depth distribution of the latter product. Better performance was achieved when the Regional Deterministic Prediction System (RDPS), available on a 10-km grid and aggregated at 100-km, was used as input to GSDM. Nevertheless, most of the analyzed ensemble forecasts were weakly consistent. Some areas of improvement are identified herein.

  7. Value Retention, Service Life, Use Intensity and Long-Term Productivity of Wood Chippers as Obtained from Contractor Records

    Full Text Available Acknowledging the absence of up-to-date empirical data on the value retention, service life and annual use of chipping machinery, in 2017 the authors surveyed the records kept by 50 contractors offering biomass chipping services. The machine fleet and operations in this survey could be taken as representative for most of Europe, where the biomass sector is well established and is facing further expansion. Data collection included the whole chipping unit, comprised of chipper, carrier and loader. Manually-fed units were excluded from the survey. The data pointed at a service life up to and exceeding 10,000 h and 10 years, which relieved any concerns about poor durability. Value retention was good, and may exceed that of other mainstream forestry equipment. Engine power was the main explanatory variable in any models to predict purchase price and productivity. The effect of this variable could explain most of the variability (>80% in the purchase price and productivity data. Results also pointed at the essential equivalence in price and productivity between PTO-driven (i.e., tractor powered and independent-engine chippers, once differences in engine power are accounted for. However, the distribution of purchase price between different components of the chipping unit was different between the two unit types, with the chipper accounting for a larger proportion of the total investment in independent-engine units. Machine power was also different, with most PTO-driven units being significantly smaller than independent-engine units, due to the limitations of existing tractors. Furthermore, half of the carriers assigned to a PTO-driven unit were subject to flexible use, i.e., they were not solely used for chipping work.

    To explore the risk factors associated with long-term mortality and the predictive value of Charlson comorbidity index (CCI) for long-term mortality in patients with pulmonary embolism (PE). A total of 234 patients with confirmed PE from the medical departments of West China Hospital of Sichuan University from January 2010 and December 2012 were enrolled, and these meeting the inclusion criteria were followed-up for 2 years after discharge. The long-term mortality was calculated and univariate and multivariate analysis were performed to identify the risk factors associated with long-term mortality of PE. All the patients were assessed the comorbidity burden with the CCI, and survival analysis was used to study its value in predicting long-term mortality in patients with PE. A total of 176 PE patients were finally included in this study, and 53 patients died during the follow-up period, with 2 years' mortality 30.1%. The univariate analysis showed diabetes (P=0.034), malignant neoplasm (P=0.001), chronic lung disease (P=0.035), liver disease (P=0.048), in bed for a long time (P=0.049), inappropriate anticoagulant therapy (P=0.016) were associated with the long-term mortality of PE patients. Among these risk factors, the multivariate analysis revealed malignant neoplasm (OR=9.28, 95%CI: 2.85-31.00, P=0.003), chronic lung disease (OR=2.96, 95%CI: 1.15-7.62, P=0.024), inappropriate anticoagulant therapy (OR=4.08, 95%CI: 1.64-10.20, P=0.003) were the independent risk factors. The median CCI scores for died PE patients during follow-up was higher than that for the survived PE patients ((2(1, 3) vs 1(0, 2), Prisk of long-term mortality compared with patients with no comorbidity (CCI=0) (95%CI: 1.14-6.00, P=0.024). The per 1-score increase of CCI was associated with 1.76-fold increased risk of long-term mortality in PE patients (95%CI: 1.04-2.97, P=0.035). Survival analysis showed that the 2-year cumulative survival of PE patients with CCI score≥1 was significant lower

    Data from open access biomolecular data resources, such as the European Nucleotide Archive and the Protein Data Bank are extensively reused within life science research for comparative studies, method development and to derive new scientific insights. Indicators that estimate the extent and utility of such secondary use of research data need to reflect this complex and highly variable data usage. By linking open access scientific literature, via Europe PubMedCentral, to the metadata in biological data resources we separate data citations associated with a deposition statement from citations that capture the subsequent, long-term, reuse of data in academia and industry.  We extend this analysis to begin to investigate citations of biomolecular resources in patent documents. We find citations in more than 8,000 patents from 2014, demonstrating substantial use and an important role for data resources in defining biological concepts in granted patents to both academic and industrial innovators. Combined together our results indicate that the citation patterns in biomedical literature and patents vary, not only due to citation practice but also according to the data resource cited. The results guard against the use of simple metrics such as citation counts and show that indicators of data use must not only take into account citations within the biomedical literature but also include reuse of data in industry and other parts of society by including patents and other scientific and technical documents such as guidelines, reports and grant applications.

    Six different calixarene-bonded phases were characterized by analyzing 36 and 26 solutes at pH 3 and 7, respectively. Dolan and Snyder's multiple term linear equation was used to correlate retention factors k' to parameters of the solutes and columns. The column parameters have been related to molecular properties of the stationary phases and new suggestions were made for the interpretation of steric selectivity. Ionic and polar interactions have been found dependent on pH value, while steric interactions are less dependent and hydrophobic interactions remain unchanged. Distinct differences of the supported interactions were confirmed between the calixarene-bonded and the common alkyl-bonded silicas. By use of the parameters, values of k' can be estimated with an average deviation of 2.50 and 7.92% at low and neutral pH-value, respectively.

    The chronically critically ill have survived acute critical illness but require prolonged mechanical ventilation. These patients are frequently transferred from acute care to long-term acute care hospitals (LTACHs) for prolonged recovery, yet many suffer setbacks requiring readmission to acute care. The patient's relatively improved condition while at the LTACH might be an opportunity for communication regarding care goals; however, there have been no prior studies of the feasibility of such conversations in the LTACH. To determine the feasibility, acceptability, and potential usefulness of conversations about serious illness with chronic critical illness patients or their surrogate decision makers after LTACH admission. We adapted an existing conversation guide for use in chronically critically ill (defined by tracheotomy for prolonged ventilation) LTACH patients or their surrogates to explore views about quality of life, understanding of medical conditions, expectations, and planning for setbacks. These conversations were conducted by one interviewer and summarized for the patients' clinicians. We surveyed patients, surrogates, and clinicians to assess acceptability. A total of 70 subjects were approached and 50 (71%) were enrolled, including 30 patients and 20 surrogates. The median duration of the conversation was 14 minutes 45 seconds [IQR 12:46, 19]. The presence of ongoing mechanical ventilation did not lead to longer conversations; in fact, conversations with patients were shorter than those with surrogates. The majority of subjects (81%) described the conversation as worthwhile. The majority of clinicians (73%) reported that the conversation offered a new and significant understanding of the patient's preferences if a setback were to occur. Conversations about serious illness care goals can be accomplished in a relatively short period of time, are acceptable to chronically critically ill patients and their surrogate decision makers in the LTACH, and are

    Peptide receptor radionuclide therapy (PRRT) with 90 Y and 177 Lu provides objective responses in neuroendocrine tumours, and is well tolerated with moderate toxicity. We aimed to identify clinical parameters predictive of long-term renal and haematological toxicity (myelodysplastic syndrome and acute leukaemia). Of 807 patients studied at IEO-Milan (1997-2013), 793 (98 %) received 177 Lu (278, 34.4 %), 90 Y (358, 44.4 %) or 177 Lu and 90 Y combined (157. 19.5 %), and 14 (2 %) received combinations of PRRT and other agents. Follow-up was 30 months (1-180 months). The parameters evaluated included renal risk factors, bone marrow toxicity and PRRT features. Data analysis included multiple regression, random forest feature selection, and recursive partitioning and regression trees. Treatment with 90 Y and 90 Y + 177 Lu was more likely to result in nephrotoxicity than treatment with 177 Lu alone (33.6 %, 25.5 % and 13.4 % of patients, respectively; p < 0.0001). Nephrotoxicity (any grade), transient and persistent, occurred in 279 patients (34.6 %) and was severe (grade 3 + 4) in 12 (1.5 %). In only 20-27 % of any nephrotoxicity was the disease modelled by risk factors and codependent associations (p < 0.0001). Hypertension and haemoglobin toxicity were the most relevant factors. Persistent toxicity occurred in 197 patients (24.3 %). In only 22-34 % of affected patients was the disease modelled by the clinical data (p < 0.0001). Hypertension (regression coefficient 0.14, p < 0.0001) and haemoglobin toxicity (regression coefficient 0.21, p < 0.0001) were pertinent factors. Persistent toxicity was associated with shorter PRRT duration from the first to the last cycle (mean 387 vs. 658 days, p < 0.004). Myelodysplastic syndrome occurred in 2.35 % of patients (modelled by the clinical data in 30 %, p < 0.0001). Platelet toxicity grade (2.05 ± 1.2 vs. 0.58 ± 0.8, p < 0.0001) and longer PRRT duration (22.6 ± 24 vs. 15.5 ± 9 months, p = 0.01) were relevant. Acute leukaemia

    Today, with the advent of modern processing techniques in the area of value addition to agri resources, food irradiation has made a big dent in terms of extension of shelf life and confidence of making the food free from microbial and other contaminants and need to be really harnessed more than what we are doing. However, there is still certain amount of stigma attached to this technology not because the technology is un-ripe but it is because of lack of awareness with the masses as regards to the safety of the foods that are processed by irradiation

    Quantifying and monitoring energy budgets at calderas, released in terms of heat output during unrest periods, is crucial to understand the state of activity, the system evolution and to draw a possible future eruptive scenario. Campi Flegrei, a restless caldera in Southern Italy, during the last years is experiencing clear signs of potential reawakening. Indeed, is now more important then ever to consider, analyse and monitor all the potential precursors, contributing to the caldera volcanic hazard assessment. We analysed the continuous long term (2006-2016) TIR images night-time collected at Pisciarelli site. This volcanic area, is located above a critical volume which recently showed an increase and clustering of earthquakes distribution and which shows the most impressive gas discharge (mainly H2O and CO2) at Campi Flegrei caldera. We treated in a statistical way the TIR images, defining an anomaly zone, which we compared to a background area. The pixel distributions, as function of the temperature, showed a generalized extreme value structure. The anomaly area, with a long tail toward high temperature values, showed a positive factor form ( f > 0, Frechet distribution). This value was constantly above zero and kept stable along the whole 2006-2016 period, while the scale factor was estimated with a decreasing trend (variance reduction). Pixels of the background TIR images, in contrast, showed a factor form between zero and a weakly negative value (f = 0 or f < 0) Gumbel or Weibull distribution). We used the location parameter as representative of the temperature distribution (which is very near the average temperature) and analysed its trend as function of time, removing the annual variation using a 365.25 days mobile average.

    In this study tools from extreme value theory (e.g. Coles, 2001; Ribatet, 2007) are applied for the first time in the field of stratospheric ozone research, as statistical analysis showed that previously used concepts assuming a Gaussian distribution (e.g. fixed deviations from mean values) of total ozone data do not address the internal data structure concerning extremes adequately. The study illustrates that tools based on extreme value theory are appropriate to identify ozone extremes and to describe the tails of the world's longest total ozone record (Arosa, Switzerland - for details see Staehelin et al., 1998a,b) (Rieder et al., 2010a). A daily moving threshold was implemented for consideration of the seasonal cycle in total ozone. The frequency of days with extreme low (termed ELOs) and extreme high (termed EHOs) total ozone and the influence of those on mean values and trends is analyzed for Arosa total ozone time series. The results show (a) an increase in ELOs and (b) a decrease in EHOs during the last decades and (c) that the overall trend during the 1970s and 1980s in total ozone is strongly dominated by changes in these extreme events. After removing the extremes, the time series shows a strongly reduced trend (reduction by a factor of 2.5 for trend in annual mean). Furthermore, it is shown that the fitted model represents the tails of the total ozone data set with very high accuracy over the entire range (including absolute monthly minima and maxima). Also the frequency distribution of ozone mini-holes (using constant thresholds) can be calculated with high accuracy. Analyzing the tails instead of a small fraction of days below constant thresholds provides deeper insight in time series properties. Excursions in the frequency of extreme events reveal "fingerprints" of dynamical factors such as ENSO or NAO, and chemical factors, such as cold Arctic vortex ozone losses, as well as major volcanic eruptions of the 20th century (e.g. Gunung Agung, El Chich

    In patients with carotid stenosis receiving medical treatment, carotid plaque echolucency has been thought to predict risk of future stroke and of other cardiovascular events. This study evaluated the prognostic value of pre-operative plaque echolucency for future stroke and cardiovascular death in patients undergoing carotid endarterectomy in the first Asymptomatic Carotid Surgery Trial (ACST-1). In ACST-1, 1832/3120 patients underwent carotid endarterectomy (CEA), of whom 894 had visual echolucency assessment according to the Gray-Weale classification. During follow-up patients were monitored both for peri-procedural (i.e. within 30 days) death, stroke, or MI, and for long-term risk of stroke or cardiovascular death. Unconditional maximum likelihood estimation was used to calculate odds ratios of peri-procedural risk and Kaplan-Meier statistics with log-rank test were used to compare cumulative long-term risks. Of 894 operated patients in whom echolucency was assessed, 458 plaques (51%) were rated as echolucent and peri-procedural risk of death/stroke/MI in these patients was non-significantly higher when compared with patients with non-echolucent plaques (OR 1.48 [95% CI 0.76-2.88], p = .241). No differences were found in the 10 year risk of any stroke (30/447 [11.6%] vs. 29/433 [11.0%], p = .900) or cardiovascular (non-stroke) death (85/447 [27.9%] vs. 93/433 [32.1%], p = .301). In ACST-1, carotid plaque echolucency assessment in patients undergoing CEA offered no predictive value with regard to peri-operative or long-term stroke risk or of cardiovascular (non-stroke) death.

    Full Text Available While hair samples are easier to collect and less expensive to store and transport than biological fluids, and hair nicotine characterizes tobacco exposure over a longer time period than blood or urine cotinine, information on its utility, compared with salivary cotinine, is still limited. We conducted a cross-sectional study with 289 participants (107 active smokers, 105 passive smokers with self-reported secondhand smoke (SHS exposure, and 77 non-smokers with no SHS exposure in Baltimore (Maryland, USA. A subset of the study participants (n = 52 were followed longitudinally over a two-month interval.  Median baseline hair nicotine concentrations for active, passive and non-smokers were 16.2, 0.36, and 0.23 ng/mg, respectively, while those for salivary cotinine were 181.0, 0.27, and 0.27 ng/mL, respectively. Hair nicotine concentrations for 10% of passive or non-smokers were higher than the 25th percentile value for active smokers while all corresponding salivary cotinine concentrations for them were lower than the value for active smokers. This study showed that hair nicotine concentration values could be used to distinguish active or heavy passive adult smokers from non-SHS exposed non-smokers. Our results indicate that hair nicotine is a useful biomarker for the assessment of long-term exposure to tobacco smoke.

    Long-term sequelae and events after coarctation repair are well described. However, the predictive value of variables from clinical follow-up investigation for late events and survival has rarely been investigated. All patients who participated in the prospective cross-sectional COALA Study in 2000 with a structural clinical investigation including blood pressure measurement and symptom-limited exercise test were contacted for reevaluation of survival, current clinical status and major cardiovascular events. Of 273 eligible patients, 209 were available for follow-up. Nine patients had died at a median age of 46years (range 30-64years), five of them due to cardiovascular complications. Late mortality after surgical intervention was 5.7% with a median age of 41years (range 16-64years). Twenty-five patients had a major cardiovascular event: 12 had procedures at the aortic valve or aortic arch, 8 had procedures for restenosis, 2 had endocarditis, 2 had a cerebrovascular insult and 1 an aortic dissection. The presence of bicuspid aortic valve (p=0.009), brachial-ankle blood pressure gradient >20mmHg (p<0.001) and reduced left ventricular function (p=0.002) correlated with major cardiovascular events. Surgical correction of coarctation of the aorta shows fairly low mortality in the long-term follow-up. Late morbidities include recoarctation, but also the consequences of the hemodynamics produced by a congenital bicuspid aortic valve, presence of which is predictive for aortic valve procedures: however the predictive value of clinical variables is limited.

    To assess the long-term healthcare costs and health outcomes in association with the access to new direct-acting antivirals (DAAs), during the first year of the National Strategic Plan for Chronic Hepatitis C (SPCHC) in patients with chronic hepatitis C (CHC) in Spain. A decision tree and a lifetime Markov model were developed to simulate the natural history, morbidity, and mortality of a cohort of 51,900 patients with CHC before (pre-DAA strategy) and after (post-DAA strategy) access to DAAs, following SPCHC approval. The percentage of patients treated, transition probabilities, disease management costs, health state utility values, sustained virologic response rates and treatment costs were obtained from the literature and published data from Spain. The results were expressed in terms of costs (€, 2016), quality-adjusted life years (QALYs) and prevention of clinical events, with an annual discount rate of 3%. The post-DAA strategy would prevent 8,667 cases of decompensated cirrhosis, 5,471 cases of hepatocellular carcinoma, 1,137 liver transplants and 9,608 liver-related deaths. The cohort of 51,900 patients would require investments of 1,606 and 1,230 million euros with the post-DAA and pre-DAA strategies, respectively. This would produce 819,674 and 665,703 QALYs. The use of new DAA-based treatments in CHC patients during the first year after the implementation of the SPCHC significantly reduced long-term morbidity and mortality and increased quality of life; demonstrating that this plan is an efficient use of public health resources.

    We sought to analyze the quality of life and the predictive value of clinical variables from previous follow-up study in patients late after surgical treatment of aortic coarctation on the quality of life. All patients, who have participated in the prospective cross-sectional COALA Study in 2000 with a structural clinical investigation including blood pressure measurement and symptom-limited exercise test were contacted for the health-related quality of life questionnaire SF-36 from January 2013 through December 2014. From 273 eligible patients, we received data from 135 patients, 9 of them died during the follow-up time at the median age of 46years (range 30-64years). Seventy-four patients did not participate in the study, other 64 patients moved to remote or unknown areas and could not be contacted. Quality of life was good in the fields of physical role and pain. However, patients reported a significant impairment in general health and in health transition, depending on the age. Arterial hypertension and variables from echocardiography or exercise testing from the COALA study were not predictive on functional health status. Quality of life in patients late after aortic coarctation repair is fairly good compared with healthy controls. Impairments in general health and health transition depend mainly on age, can be explained due to numerous comorbidities and reinterventions in long-term. The predictive value of the commonly assessed clinical variables on quality of life is limited. Copyright © 2017. Published by Elsevier B.V.

    Discharge-planning decisions about long-term care (LTC) can be difficult and distressing for older people, families and discharge-planning health professionals. Retrospective research suggests that despite good intentions and a shared focus on the best interests of the older person, stakeholders may hold very different values about good outcomes and how to decide them. We aimed to compare the opinions and values of frail elders living at home, younger relatives and health professionals experienced in discharge-planning, prospectively: before, not after, a LTC decision. We interviewed three types of stakeholders (10 older people, 8 relatives and 18 health professionals) using a hypothetical vignette about a frail elder leaving hospital. In a mixed methods design, we quantitatively compared the discharge plans and decision-makers that stakeholders suggested, and qualitatively analysed the 36 interview transcripts for participants' articulation of underlying values during these discussions. Older participants often suggested safe restrictive options (residential care, proxy decision-making) for the hypothetical frail elder, while advocating autonomy for themselves. Younger people generally endorsed autonomous decision-making and less restrictive discharge options especially if the elder was mentally competent, but reported difficult ethical tensions between safety and autonomy. Individual personality and preferences, mental capacity, and the importance of personal care in supporting autonomy were central themes consistent with the Ecological Theory of Aging. Accordingly, discharge planners can usefully articulate the balance of safety and autonomy, conceptualizing home care as maintaining independence rather than accepting dependence. Ethical training should incorporate sophisticated models of practice specifying both psychological and physical safety as components of beneficence. Few elders adopt a consumer approach to LTC: health professionals can encourage mid

    Purpose: To determine whether post-treatment prostate-specific antigen (ptPSA) values at 12 months and other clinical parameters predict long-term PSA relapse-free survival (PRFS) following prostate seed brachytherapy. Methods and Materials: Records of 204 hormone-naieve patients with localized adenocarcinoma of the prostate treated at St. Mary's Regional Medical Center in Reno, NV, and at Carson Tahoe Regional Medical Center in Carson City, NV, between 1998 and 2003, using I-125 or Pd-103 seed brachytherapy, were retrospectively analyzed. Treatment planning was done using a preplanned, modified peripheral loading technique. A total of 185 of 204 patients had PSA records at 12 months after implant. Variables included were age, initial pretreatment PSA, Gleason score, T stage, National Comprehensive Cancer Network (NCCN) risk group (RG), perineural invasion (PNI), external beam boost, dose, and ptPSA levels at 12 months with cutpoints at {<=}1, 1.01 to 2.00, 2.01 to 3.00, and >3.00 ng/ml. Results: Median follow-up was 80 months, and median age was 69 years. The numbers of patients stratified by NCCN low, intermediate, and high RG were 110:65:10, respectively. Monotherapy and boost prescription doses were 145 Gy and 110 Gy for I-125, and 125 Gy and 100 Gy for Pd-103 seeds, respectively. The median dose (D90) was 95.4% of the prescribed dose. The 5-year PRFS at the 12-months ptPSA levels of {<=}1, 1.01 to 2.00, 2.01 to 3.00, and >3.00 ng/ml were 98.5%, 85.7%, 61.5%, and 22.2%, respectively. The 10-year PRFS at the 12-months ptPSA levels of {<=}1 and 1.01 to 2.00 ng/ml were 90.5% and 85.7%, respectively. In multivariate analysis, both ptPSA and PNI were significant independent predictors of PRFS. Hazard ratios (HR) for ptPSA levels at {<=}1, 1.01 to 2.00, 2.01 to 3.00, and >3.00 ng/ml at 12 months were 1, 4.96, 27.57, and 65.10, respectively. PNI had an HR of 6.1 (p = 0.009). Conclusions: Presence of PNI and ptPSA values at 12 months are strong prognostic

    The association of blood pressure levels during the acute phase of ischemic stroke with outcome remains controversial. The objective of this systematic review is to assess the predictive value for stroke outcome assessed by the modified Rankin scale score of systolic and diastolic blood pressure, measured by ambulatory blood pressure monitoring methods during the acute phase of ischemic stroke, compared with the values of casually derived blood pressure measurement on admission. We searched for studies with patients admitted within 24 h of stroke onset, and who had ambulatory blood pressure monitoring during the first 24 h of admission. We identified studies that reported blood pressure in those with good outcome and in those with poor outcome at end of follow-up, and performed a meta-analysis of the effect of mean blood pressure on outcome. High systolic and diastolic blood pressure levels derived with ambulatory blood pressure monitoring were associated with poor short-, medium-, and long-term outcome, but the same was not found for casual blood pressure measurements. An increase in systolic blood pressure of 9·1 mmHg (95% confidence interval: 6·6-11·6, P < 0·001; I(2)  = 9%) and an increase in diastolic blood pressure of 2·3 mmHg (95% confidence interval: 0·8-3·7, P = 0·002; I(2)  = 0%) were associated with poor outcome. Higher systolic and diastolic blood pressure levels derived with ambulatory blood pressure monitoring were associated with poor outcome. The same was not found for higher casual blood pressure measurements on admission, and it is possible that ambulatory blood pressure monitoring conveys better prognostic information. © 2015 World Stroke Organization.

    Background Limited research studies with a large sample size were performed to evaluate the prognostic value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) for in-hospital or long-term poor outcomes in patients with infective endocarditis. Methods A total of 703 patients with infective endocarditis were enrolled and divided into four groups according to admission NT-pro-BNP (pg/mL) quartiles: Q1 (3522). Multivariate regression was used to determine independent risk of NT-proBNP for in-hospital and one-year death. Results In-hospital death occurred in 9.0% of patients. The in-hospital mortality was increased from the lowest to the highest NT-proBNP quartiles (1.1%, 3.4%, 9.1% and 22.3%, P  2260 pg/mL had 76.2% sensitivity and 69.1% specificity for predicting in-hospital death. Kaplan-Meier analysis showed that patients with NT-proBNP > 2260 pg/ml had a worse prognosis than those without (log-rank test 18.84, P endocarditis.

    Purpose: Definition of the prognostic value of clinical and morphological findings in the mid-term follow-up of OCD of the femoral condyle and talus. Demonstration of the consolidation of OCD on MRI depending on different therapies. Materials and Methods: 76 patients were examined before and at an average of 30 months after conservative or surgical therapy using T 1 and T 2 weighted SE and 3D-FISP sequences and contrast enhanced studies. Six clinical (age, gender, site, duration and severity of symptoms, therapy) and six morphological (size, signal intensity, fragmentation, contrast enhancement, condition of cartilage, staging) data were registered on first MRI and correlated with the degree of consolidation of OCD (partial and complete remission, no change and progression) on control MRI. Results: Patients under 17 years showed partial or complete remissions in 73%, those of 17 years or older in 33%. Conservatively treated patients had a higher remission rate (54%) than those treated with different surgical techniques (drilling 50%, refixation 43%, abrasio 38%). Small OCDs had a higher remission rate than large lesions (63% vs. 33%). OCDs covered with intact cartilage healed better than lesions with chondral defects (61% vs. 26%). Contrast enhancing fragments had a better prognosis than non-enhancing lesions (100% vs. 40%). Conclusions: Prognosis of OCD can be better estimated when size of OCD, condition of cartilage and enhancement of contrast agent is graduated with MRI and patient age is registered. The consequences for therapy planning are great. (orig.) [de

    To determine the prognostic value of pro B-type natriuretic peptide (pro-BNP) to predict mortality after transcatheter aortic valve implantation (TAVI). Logistic EuroSCORE (LES) overestimates observed mortality after TAVI. A new risk score specific to TAVI is needed to accurately assess mortality and outcome. Eighty-five patients were included. Indications for TAVI were nonoperable or surgically high-risk patients (LES>20%). Pro-BNP was measured 24h before the procedure. Cox proportional hazards model was used to evaluate clinical factors. The predictive accuracy of these Cox models was determined by using time-dependent receiver operating characteristic (ROC) curves. Pro-BNP levels (log-transformed) were significantly higher in non-survivors than in survivors at 30 days (3.36 ± 0.43 vs. 3.81 ± 0.43, p<0.004) and at the end of follow-up (3.34 ± 0.42 vs. 3.63 ± 0.48, p<0.011). Multivariate analysis revealed that only increased log pro-BNP levels were associated with higher mortality rate at short [hazard ratio (HR) (95% confidence intervals (CI)]=5.35 (1.74-16.5), p=0.003] and long-term follow-ups [HR=11 (CI: 1.51-81.3), p=0.018]. LES was not associated with increased mortality at either time point [HR=1.03 (CI: 0.95-1.10), p=0.483 and HR=1.03 (CI: 0.98-1.07), p=0.230, respectively]. At 30, 90, 180, and 365 days, the c-index was 0.72 for log pro-BNP and 0.63 for LES (p=0.044). Pre-procedure log transform of plasma pro-BNP levels are an independent and strong predictor of short- and long-term outcomes after TAVI and are more discriminatory than LES.

    Full Text Available Introduction: Increased numbers of nucleated red blood cells (NRBC circulating in the blood of neonates can be associated with relative hypoxia and adverse outcomes. Thus, the aim of this study was to assess the NRBC count during the first week of life in neonates diagnosed with asphyxia as compared to healthy neonates and to determine the short-term morbidity and mortality for the affected babies. Methods: The cross-sectional study compared 15 healthy neonates with 15 neonates diagnosed with asphyxia confirmed by pH of cord blood or Apgar scores. The nucleated red blood cell (NRBC counts were calculated right after birth, and on days 3 and 7, and the hematological parameters of umbilical cord blood were also evaluated. The infants were followed for mortality and associated morbidity. Statistical analysis was conducted using the Mann-Whitney U test, analysis of variance, chi-square tests, and Pearson’s correlation coefficient. A p-value < 0.05 was considered as statistically significant. Results: The initial NRBC counts were significantly higher in the asphyxiated group than in the control group and the difference remained significant through the end of first week. All of the umbilical cord blood parameters were significantly lower in the study group and were negatively correlated with the NRBC count. At birth, higher NRBC count correlated with higher mortality. conclution: Results show that NRBC count is a useful predictive factor for neonatal asphyxia through the end of the first week of life, although a larger study population and a longer follow up period seems to be necessary.

    Questionnaires are valuable for population surveys of mental health. Different survey instruments may however give different results. The present study compares two mental health instruments, the Major Depression Inventory (MDI) and the Mental Health Inventory (MHI-5), in regard to their prediction of long-term sickness absence. Questionnaire data was collected from N = 4153 Danish employees. The questionnaire included the MDI and the MHI-5. The information of long-term sickness absence was obtained from a register. We used Cox regression to calculate covariance adjusted hazard ratios for long-term sickness absence for both measures. Both the MDI and the MHI-5 had a highly significant prediction of long-term sickness absence. A one standard deviation change in score was associated with an increased risk of long-term sickness absence of 27% for the MDI and 37% for the MHI-5. When both measures were included in the same analysis, the MHI-5 performed best. In general population surveys, the MHI-5 is a better predictor of long-term sickness absence than the MDI.

    Soil stabilization is an effort to improve engineering properties of soil. The conventional soil stabilization is by adding additives to the soil such as Portland cement, lime, and bitumen. The clay stabilization research was done by adding gypsum and volcanic ash. The research purposes were to find out the value of engineering properties of clay due to the addition of 2% gypsum and 2% - 15% volcanic ash. The soil was classified as Clay - Low Plasticity (CL) based on USCS and was classified as A-7-6 (10) based on AASHTO classification system. The UCT values of original soil and original soil plus 2% gypsum were 1.40 kg/cm2 and 1.66 kg/cm2 respectively. The CBR soaked and unsoaked values of original soil were 4.44% and 6.28% correspondingly. Meanwhile, CBR soaked and CBR unsoaked values of original soil plus 2% gypsum were 6.74% and 8.02% respectively. The research results showed that the additives materials of gypsum and volcanic ash improved the engineering properties of clay. The UCT result from the stabilized soil by 2% gypsum and 10% volcanic ash gave value of 2.79 kg/cm2 (increased 99.28% from original soil). For CBR test, the most effective mixture were in variation of 2% gypsum and 9% volcanic ash which gave value of 9.07% (104.27% increase from original soil) for CBR soaked and 10.29% (63.85% increase from original soil) for CBR unsoaked. The stabilized soil with 2% gypsum and 9% volcanic ash was classified as CL based on USCS and was classified as A-6 (4) based on AASHTO classification system.

    The aim of this study is to compare a two-wavelength light emitting diode-based tissue oximeter (INVOS), which is designed to show trends in tissue oxygenation, with a four-wavelength laser-based oximeter (FORE-SIGHT), designed to deliver absolute values of tissue oxygenation. Simultaneous values of cerebral tissue oxygenation (StO2) are measured using both devices in 15 term and 15 preterm clinically stable newborns on the first and third day of life. Values are recorded simultaneously in two periods between which oximeter sensor positions are switched to the contralateral side. Agreement between StO2 values before and after the change of sensor position is analyzed. We find that mean cerebral StO2 values are similar between devices for term and preterm babies, but INVOS shows StO2 values spread over a wider range, with wider standard deviations than shown by the FORE-SIGHT. There is relatively good agreement with a bias up to 3.5% and limits of agreement up to 11.8%. Measurements from each side of the forehead show better repeatability for the FORE-SIGHT monitor. We conclude that performance of the two devices is probably acceptable for clinical purposes. Both performed sufficiently well, but the use of FORE-SIGHT may be associated with tighter range and better repeatability of data.

    Combined application of metronidazole and short-term hyperglycemia under fractionated irradiation of sarcoma-45, 340 in white rats-males is studied. Tumors were γ-irradiated with 60 Co threefold in 48 hours at 15 Gy single dose or irradiated threefold in a week at 20, 25 and 30 Gy doses. Efficiency of experimental therapy is cheked by dynamics of tumor regression, a number of animals with tumors reabsorbed temporarily, a number of animals recovered and time of tumor grouth up to the initial volume. It is established that combined application of metronidazole and short-term hyperglycemia under fractionated irradiation increases essentially the efficiency of radiotherapy carried out by large fractions with great time intervals. 7 refs.; 1 fig.; 2 tabs

    Red Cell Distribution Width (RDW) prognostic value in patients with Acute Coronary Syndrome (ACS) has been well validated whereas that of Platelet Distribution Width (PDW) is less well known. Investigate the incremental prognostic value, on top of GRACE risk score, of a new variable resulting from the combination of RDW and PDW. Consecutive patients with ACS. Complete blood count, with RDW and PDW, was obtained. Primary endpoint was one-year all-cause mortality and Cox regression models were used to measure the influence of RDW and PDW on patients' survival time. A new combination categorical variable (RDW/PDW) was created with both discretized RDW and PDW and logistic regression models were used. Predictive value and discriminative ability of the model with GRACE risk score alone and of the model with inclusion of RDW/PDW was assessed. We included 787 patients. Hospital and one-year mortality rates were 5.1% and 7.8%, respectively. Both continuous RDW and PDW were independent predictors of death. The best cut-off for RDW was 13.9%, and 14.5% for PDW. Inclusion of RDW/PDW in a model with GRACE risk score improved the AUC from 0.81 (95% CI 0.75-0.86) to 0.84 (95% CI 0.79-0.90) (p=0.024) with an improvement in total NRI (56%) and IDI (0.048). Simple markers such as RDW and PDW can be useful in risk stratification of death after ACS. Combining both markers with GRACE risk score improved the predictive value for all-cause mortality and reduced the estimated risk of those who did not die. © The European Society of Cardiology 2014.

    This study explores experiences of patients suffering from Korsakoff's syndrome. It contributes to improved reflection on the value of patient knowledge. An ethics of care perspective states the importance of moving to patients in their vulnerable state of being, and to figure out patients' individual needs necessary to provide good care. The information given by patients suffering from Korsakoff's syndrome might be mistaken, invented and even not true. The value of these patients' experiences and knowledge had not been researched to date. Data from six in-depth interviews were analysed concurrently through the constant comparative method. The principles of voluntariness, confidentiality and anonymity were respected during the research process. Four important themes within patients' knowledge emerged: health condition, involuntary admission into the nursing home, the daily routine and interpretation of the caring abilities of healthcare professionals. The findings show that our respondents were able to provide a window into their inner perspective. This study deepens our understanding of the value of patient knowledge in situations where patients see the world in a different manner as do healthcare professionals. The conversations revealed personal subjective knowledge which our respondents create and live by. Healthcare professionals are encouraged to discover and affirm the understandings of these patients, and not be prepossessed due to the diagnosis or general nursing home rules. Understanding patients' unique knowledge through appreciation of the complexity and richness of different views on the situation can assist to give a more humane response to individual needs and pain. Health staff in healthcare institutions are encouraged to evaluate the - unintended - effect of rigidly applied nursing home rules, and the government is challenged to rethink its policy about care, and provide more resources permitting relational care that nurtures the dignity of

    The aims of this study were to investigate gross motor development in Greek infants and establish AIMS percentile curves and to examine possible association of AIMS scores with socioeconomic parameters. Mean AIMS scores of 1068 healthy Greek full-term infants were compared at monthly age level with the respective mean scores of the Canadian normative sample. In a subgroup of 345 study participants, parents provided, via interview, information about family socioeconomic status. Multiple linear regression analysis was performed to evaluate the relationship of infant motor development with socioeconomic parameters. Mean AIMS scores did not differ significantly between Greek and Canadian infants in any of the 19 monthly levels of age. In multiple linear regression analysis, the educational level of the mother and also whether the infant was being raised by grandparents/babysitter were significantly associated with gross motor development (p=0.02 and psocioeconomic factors are associated with the infants' motor development.

    to explore the use of social networking sites (SNS) by adolescent mothers in Western Australia (WA) in relation to social support and the building of social capital. a constructionist narrative inquiry approach was employed to guide the research design and processes. Approval was gained from the university human ethics department. Sampling was purposeful and data were collected using in-depth interviews with seven adolescent mothers in WA. interviews were undertaken within the homes of adolescent mothers across WA. from within three fundamental domains of social support; tangible, emotional and informational support, provided by SNS use, five key themes were identified from the narratives. 'Social connectedness' was identified as a form of tangible support, sometimes termed 'practical' or 'instrumental' support. This theme incorporates connectedness with family, friends, and peers and across new and existing social groups. Three themes were identified that relate to emotional support; 'increased parenting confidence'; 'reduced parental stress' and 'enhanced self-disclosure' afforded by use of SNS. 'Access to information' was identified in terms of informational support, with participants often highlighting SNS use as their primary portal for information and advice. the findings of this study suggest that SNS use affords adolescent mothers in WA access to tangible, informational and emotional support and thus is a valuable source of social capital for these mothers. This study provides a platform for further exploration into this phenomenon, and possible implications include the potential for midwives and health care professionals to promote the benefits of SNS use with, and for, this group of mothers, or to incorporate SNS use into modern health care practices to further develop the potential for improved social capital related outcomes for them.

    The chemical changes (oxidation/nitrosation) of meat proteins during digestion lead to a decrease in their nutritional value. Moreover, oxidized and nitrosated amino acids are suspected to promote various human pathologies. To investigate the mechanisms and the kinetics of these endogenous protein modifications, we used a dynamic artificial digestive system (DIDGI®) that mimics the physicochemical conditions of digestion. The combined effect of meat cooking and endogenous addition of ascorbate and nitrite was evaluated on protein oxidation (by measuring carbonyl groups), protein nitrosation (by measuring nitrosamines), and proteolysis. Considerable carbonylation was observed in the digestive tract, especially under the acidic conditions of the stomach. Nitrosamines, caused by ammonia oxidation, were formed in conditions in which no nitrite was added, although the addition of nitrite in the model significantly increased their levels. Meat cooking and nitrite addition significantly decreased protein digestion. The interactions between all the changes affecting the proteins are discussed. Copyright © 2017 Elsevier Ltd.

    Low haemoglobin concentrations may be predictive of incident tuberculosis (TB) and death in HIV-infected patients receiving antiretroviral therapy (ART), but data are limited and inconsistent. We examined these relationships retrospectively in a long-term South African ART cohort with multiple time-updated haemoglobin measurements. Prospectively collected clinical data on patients receiving ART for up to 8 years in a community-based cohort were analysed. Time-updated haemoglobin concentrations, CD4 counts and HIV viral loads were recorded, and TB diagnoses and deaths from all causes were ascertained. Anaemia severity was classified using World Health Organization criteria. TB incidence and mortality rates were calculated and Poisson regression models were used to identify independent predictors of incident TB and mortality, respectively. During a median follow-up of 5.0 years (IQR, 2.5-5.8) of 1,521 patients, 476 cases of incident TB and 192 deaths occurred during 6,459 person-years (PYs) of follow-up. TB incidence rates were strongly associated with time-updated anaemia severity; those without anaemia had a rate of 4.4 (95%CI, 3.8-5.1) cases/100 PYs compared to 10.0 (95%CI, 8.3-12.1), 26.6 (95%CI, 22.5-31.7) and 87.8 (95%CI, 57.0-138.2) cases/100 PYs in those with mild, moderate and severe anaemia, respectively. Similarly, mortality rates in those with no anaemia or mild, moderate and severe time-updated anaemia were 1.1 (95%CI, 0.8-1.5), 3.5 (95%CI, 2.7-4.8), 11.8 (95%CI, 9.5-14.8) and 28.2 (95%CI, 16.5-51.5) cases/100 PYs, respectively. Moderate and severe anaemia (time-updated) during ART were the strongest independent predictors for incident TB (adjusted IRR = 3.8 [95%CI, 3.0-4.8] and 8.2 [95%CI, 5.3-12.7], respectively) and for mortality (adjusted IRR = 6.0 [95%CI, 3.9-9.2] and adjusted IRR = 8.0 [95%CI, 3.9-16.4], respectively). Increasing severity of anaemia was associated with exceptionally high rates of both incident TB and mortality during

    Full Text Available Data from open access biomolecular data resources, such as the European Nucleotide Archive and the Protein Data Bank are extensively reused within life science research for comparative studies, method development and to derive new scientific insights. Indicators that estimate the extent and utility of such secondary use of research data need to reflect this complex and highly variable data usage. By linking open access scientific literature, via Europe PubMedCentral, to the metadata in biological data resources we separate data citations associated with a deposition statement from citations that capture the subsequent, long-term, reuse of data in academia and industry.  We extend this analysis to begin to investigate citations of biomolecular resources in patent documents. We find citations in more than 8,000 patents from 2014, demonstrating substantial use and an important role for data resources in defining biological concepts in granted patents to both academic and industrial innovators. Combined together our results indicate that the citation patterns in biomedical literature and patents vary, not only due to citation practice but also according to the data resource cited. The results guard against the use of simple metrics such as citation counts and show that indicators of data use must not only take into account citations within the biomedical literature but also include reuse of data in industry and other parts of society by including patents and other scientific and technical documents such as guidelines, reports and grant applications.

    Magnetic resonance spectroscopy can identify brain metabolic changes in perinatal asphyxia by providing ratios of metabolites, such as choline (Cho), creatine (Cr), N-acetyl aspartate (NAA) and lactate (Lact) [Cho/Cr, Lact/NAA, etc.]. The purpose of this study was to quantify the separate white and grey matter metabolites in a slab cranial to the ventricles and relate these to the outcome. A standard 2D-chemical shift imaging protocol was used for measuring a transverse volume of interest located cranial to the ventricles allowing for direct comparison of the metabolites in white and grey matter brain tissue in 24 term asphyxiated newborns aged 3 to 16 days. Cho, NAA and Lact showed significant differences between four subgroups of asphyxiated infants with more and less favourable outcomes. High levels of Cho and Lact in the grey matter differentiated non-survivors from survivors (P = 0.003 and P = 0.017, respectively). In perinatal asphyxia the levels of Cho, NAA and Lact in both white and grey matter brain tissue are affected. The levels of Cho and Lact measured in the grey matter are the most indicative of survival. It is therefore advised to include grey matter brain tissue in the region of interest examined by multivoxel MR spectroscopy. (orig.)

    Growth differentiation factor-15 (GDF-15), Cystatin C and C-reactive protein (CRP) have been discussed as biomarkers for prediction of cardiac diseases. The aim of this study was to investigate the predictive value of single and repeated measurements of GDF-15 compared to Cystatin C and CRP for incidence of heart failure (HF) and death due to coronary heart disease (CHD) in the general population. Levels of GDF-15, CRP and Cystatin C were determined in three repeated measurements collected 5 years apart in the DAN-MONICA (Danish-Multinational MONitoring of trends and determinants in Cardiovascular disease) cohort (participants at baseline n = 3785). Cox regression models adjusted for cardiovascular risk factors revealed significantly increased hazard ratios (HR) for GDF-15 for incident HF 1.36 (HR per interquartile range (IQR) increase, 95% confidence interval (CI): 1.16; 1.59) and for death from CHD 1.51 (HR per IQR increase, 95% CI: 1.31, 1.75) (both with p<0.001). Joint modeling of time-to-event and longitudinal GDF-15 over a median 27-year follow-up period showed that the marker evolution was positively associated with death of CHD (HR per IQR increase 3.02 95% CI: (2.26, 4.04), p < 0.001) and HF (HR per IQR increase 2.12 95% CI: (1.54, 2.92), p<0.001). However using Cox models with follow-up time starting at the time of the third examination, serial measurement of GDF-15, modeled as changes between the measurements, did not improve prediction over that of the most recent measurement. GDF-15 is a promising biomarker for prediction of HF and death due to CHD in the general population, which may provide prognostic information to already established clinical biomarkers. Repeated measurements of GDF-15 displayed only a slight improvement in the prediction of these endpoints compared to a single measurement.

Our study was designed to assess whether AGR is associated with the prognosis of gastric cancer patients. Patients and methods: A total of 507 gastric cancer patients between 2005 and 2012 were included. The AGR was defined as the ratio of serum albumin to nonalbumin and calculated by the equation: albumin/(total protein - albumin. Furthermore, AGR was divided into two groups (low and high using the X-tile software. Survival analysis stratified by AGR groups was performed. Results: The mean survival time for each group was 36.62 months (95% CI: 33.92–39.32 for the low AGR group and 48.95 months (95% CI: 41.93–55.96, P=0.003 for the high AGR group. Patients in the high group (AGR ≥1.93 had a significantly lower 5-year mortality in comparison with the low group (AGR <1.93 (52.4% vs 78.5%, P=0.003. The high AGR group showed obviously better overall survival than the low AGR group according to Kaplan–Meier curves (P=0.003. Multivariate analysis showed that AGR was an independent predictive factor of prognosis in gastric patients. Conclusion: Pretreatment AGR is a significant and independent predictive factor of prognosis. Keywords: gastric cancer, survival, inflammation, albumin–globulin ratio

    To study the predictive value of whole-body magnetic resonance (MR) imaging for the occurrence of cardiac and cerebrovascular events in a cohort of patients with diabetes mellitus (DM). This HIPAA-compliant study was approved by the institutional review board. Informed consent was obtained from all patients before enrollment into the study. The authors followed up 65 patients with DM (types 1 and 2) who underwent a comprehensive, contrast material-enhanced whole-body MR imaging protocol, including brain, cardiac, and vascular sequences at baseline. Follow-up was performed by phone interview. The primary endpoint was a major adverse cardiac and cerebrovascular event (MACCE), which was defined as composite cardiac-cerebrovascular death, myocardial infarction, cerebrovascular event, or revascularization. MR images were assessed for the presence of systemic atherosclerotic vessel changes, white matter lesions, and myocardial changes. Kaplan-Meier survival and Cox regression analyses were performed to determine associations. Follow-up was completed in 61 patients (94%; median age, 67.5 years; 30 women [49%]; median follow-up, 70 months); 14 of the 61 patients (23%) experienced MACCE. Although normal whole-body MR imaging excluded MACCE during the follow-up period (0%; 95% confidence interval [CI]: 0%, 17%), any detectable ischemic and/or atherosclerotic changes at whole-body MR imaging (prevalence, 66%) conferred a cumulative event rate of 20% at 3 years and 35% at 6 years. Whole-body MR imaging summary estimate of disease was strongly predictive for MACCE (one increment of vessel score and each territory with atherosclerotic changes: hazard ratio, 13.2 [95% CI: 4.5, 40.1] and 3.9 [95% CI: 2.2, 7.5], respectively), also beyond clinical characteristics as well as individual cardiac or cerebrovascular MR findings. These initial data indicate that disease burden as assessed with whole-body MR imaging confers strong prognostic information in patients with DM. Online

    The authors define the notions of use values and price of plutonium. They give a 'simplified parametrized model' simulating the equilibrium of the offer and the demand in time, concerning the plutonium and the price deriving from the relative scarcity of this metal, taking into account the technical and economic operating parameters of the various reactors confronted. This model is simple enough to allow direct computations and establish clear relations between the various parameters. The use of the linear programmes method allows on the other hand a wide extension of the model. This report includes three main parts: I - General description of the study (without detailed calculations) II - Mathematical development of the simplified parametrized model and application (the basic data and the results of the calculations are given) III - Appendices (giving the detailed computations of part II).

    To evaluate the long-term prognostic value of risk scores in the setting of drug-eluting stent (DES) implantation for uLMCA. Data on the prognostic value of novel risk scores developed to select the most appropriate revascularization strategy in patients undergoing DES implantation for uLMCA disease are relatively limited. The study represents a patient-level pooled analysis of the ISAR-LEFT-MAIN (607 patients randomized to paclitaxel-eluting or sirolimus-eluting stents) and the ISAR-LEFT-MAIN-2 (650 patients randomized to everolimus-eluting or zotarolimus-eluting stents) randomized trials. The Syntax Score (SxScore) as well the Syntax Score II (SS-II), the EuroSCORE and the Global Risk Classification (GRC) were calculated. The primary outcome was all-cause mortality. At a mean follow-up of 3 years there were 160 deaths (12.7%). The death-incidence was significantly higher in the upper tertiles than in the intermediate or lower ones for all risk scores (log-rank test P risk scores were able to stratify the mortality risk at long-term follow-up.

    Full Text Available This study is to examine the determinants of management’s fair value choice decision for reporting long term non-financial assets in companies listed on “Borsa Istanbul Equity Market” whose financial statements have to be prepared under International Accounting Standards / Inte rnational Financial Reporting Standards and thus Turkey Accounting Standards / Turkey Financial Reporting Standards. In this study, Watts and Zimmerman’s Positive Accounting Theory methodology is adopted, and Mann -Whitney U test and logistic regression analysis have been used to analyze data. As a result of analysis, it has been identified that companies reporting property, plant and equipment at revalued amount are funded by more debtand to besmaller companies than companies reporting those assets at amortized historical cost. However, the results indicate that debt contracting, political cost and information asymmetry factors are not the determinants of management’s decision for reporting long term non-financial assets at fair value. The company size explains the management’s decision for reporting property, plant and equipment at revalued amount,but contrary to what is predicted, the evaluation method is chosen by small companies

    Diabetic and new-onset diabetic patients with hypertension have higher cardiac morbidity than patients without diabetes. We aimed to investigate whether baseline predictors of cardiac morbidity, the major constituent of the primary endpoint in the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial, were different in patients with diabetes and new-onset diabetes compared to patients without diabetes. In total, 15,245 high-risk hypertensive patients in the VALUE trial were followed for an average of 4.2 years. At baseline, 5250 patients were diabetic by the 1999 World Health Organization criteria, 1298 patients developed new-onset diabetes and 8697 patients stayed non-diabetic during follow-up. Cardiac morbidity was defined as a composite of myocardial infarction and heart failure requiring hospitalization, and baseline predictors were identified by univariate and multivariate stepwise Cox regression analyses. History of coronary heart disease (CHD) and age were the most important predictors of cardiac morbidity in both diabetic and non-diabetic patients. History of CHD, history of stroke and age were the only significant predictors of cardiac morbidity in patients with new-onset diabetes. Predictors of cardiac morbidity, in particular history of CHD and age, were essentially the same in high-risk hypertensive patients with diabetes, new-onset diabetes and without diabetes who participated in the VALUE trial.

    ğerlendirilmiştir. Despite the recent scientific and technological developments, such problems as the state of violence and fear in the world, material and spiritual dissatisfaction, brutality, injustice, insensitivity towards what is happening in the world, unhappiness, and dissatisfaction with life render the importance of values education that is missing and its transmission and encourage the governments to revitalize some national and universal values and establish a new set of contemporary values, thus bring back the social control that has almost extincted. With this in mind, “values education” has been the subject of numerous studies all over the world. Since 1995, it has been seriously emphasized and designed as a project called “Living Values Education” to attempt to revitalize the values that are on the brink of extinction. In this regard, in contemplation of values being taught in schools, a set of target values within the curriculum of all the courses taught in primary and secondary education has been determined in our country as well, considering the relevance of these values to the courses. In this study, we have attempted to read the poems by Âşık Veysel, who is one of the most important characters of Turkish folk literature in the twentieth century, in terms of “values education” considering that many of his works enable the national and spiritual values of Turkish literature to be taught and transmitted and give advices to his target readers. The results of studying on 158 poems brought about the fact that Aşık Veysel told his readers many things in the scope of values education. After identifying over 60 different values, at different frequency of occurrence, within these poems that consist of about 900 quadrants, the findings are evaluated and interpreted in terms of values education.

    In making calculations for the purposes of radiation protection, numerical values for parameters used in the calculations are selected. In some cases, data directly applicable to the set of conditions for which the calculations are to be made are unavailable. Therefore, the selection of the values for these parameters may be based on more general data available from the literature or other sources. These values may be referred to as 'default values', that is, values used in default of those based on directly applicable data. The following policy will be applied by Atomic Energy Control Board (AECB) staff in reviewing the radiation protection aspects of submissions associated with licensing, in participating with other organizations in the development of codes and standards, and in any other work which relies to some extent on using default values

    National and international guidelines recommend fasting lipid panel measurement for risk stratification of patients for prevention of cardiovascular events. However, the prognostic value of fasting versus nonfasting low-density lipoprotein cholesterol (LDL-C) is uncertain. Patients enrolled in the National Health and Nutrition Examination Survey III (NHANES-III), a nationally representative cross-sectional survey performed from 1988 to 1994, were stratified on the basis of fasting status (≥8 or fasting and nonfasting cohorts with similar baseline characteristics. The risk of outcomes as a function of LDL-C and fasting status was assessed with the use of receiver operating characteristic curves and bootstrapping methods. The interaction between fasting status and LDL-C was assessed with Cox proportional hazards modeling. Primary outcome was all-cause mortality. Secondary outcome was cardiovascular mortality. One-to-one matching based on propensity score yielded 4299 pairs of fasting and nonfasting individuals. For the primary outcome, fasting LDL-C yielded prognostic value similar to that for nonfasting LDL-C (C statistic=0.59 [95% confidence interval, 0.57-0.61] versus 0.58 [95% confidence interval, 0.56-0.60]; P=0.73), and LDL-C by fasting status interaction term in the Cox proportional hazards model was not significant (Pinteraction=0.11). Similar results were seen for the secondary outcome (fasting versus nonfasting C statistic=0.62 [95% confidence interval, 0.60-0.66] versus 0.62 [95% confidence interval, 0.60-0.66]; P=0.96; Pinteraction=0.34). Nonfasting LDL-C has prognostic value similar to that of fasting LDL-C. National and international agencies should consider reevaluating the recommendation that patients fast before obtaining a lipid panel. © 2014 American Heart Association, Inc.

    To investigate whether the addition of left ventricular ejection fraction (LVEF) to the TIMI risk score enhances the prediction of in-hospital and long-term death in ST segment elevation myocardial infarction (STEMI) patients. 673 patients with STEMI were divided into three groups based on TIMI risk score for STEMI: low-risk group (TIMI ≤3, n = 213), moderate-risk group (TIMI 4-6, n = 285), and high-risk group (TIMI ≥7, n = 175). The predictive value was evaluated using the receiver operating characteristic. Multivariate logistic regression was used to determine risk predictors. The rates of in-hospital death (0.5 vs 3.2 vs 10.3 %, p risk group. Multivariate analysis showed that TIMI risk score (OR 1.24, 95 % CI 1.04-1.48, P = 0.015) and LVEF (OR 3.85, 95 % CI 1.58-10.43, P = 0.004) were independent predictors of in-hospital death. LVEF had good predictive value for in-hospital death (AUC: 0.838 vs 0.803, p = 0.571) or 1-year death (AUC: 0.743 vs 0.728, p = 0.775), which was similar to TIMI risk score. When compared with the TIMI risk score alone, the addition of LVEF was associated with significant improvements in predicting in-hospital (AUC: 0.854 vs 0.803, p = 0.033) or 1-year death (AUC: 0.763 vs 0.728, p = 0.016). The addition of LVEF to TIMI risk score enhanced net reclassification improvement (0.864 for in-hospital death, p value to TIMI risk score.

    Full Text Available Orkhon Inscriptions is one of the largest cultural heritages of the Turkish nation. These cultural assets are the property of being the memory of the nation they were born through. Indeed since these monuments transfer the values they contain to the future, they have a characteristic that is the masterpiece of the Turkish nation which plays a significant role. What a nation keeps alive is its values. In this sense, for the Turkish nation, it is important that these monuments is examined in terms of the transfer value and is used in educational activities. The aim of this study is to identify the values in Tunyuquq Monument which is the first of Orkhon Inscriptions and to determine the importance of these values in Turkish value transfer. In the study, the descriptive analysis, one of the qualitative research techniques, has been used. By the researcher, values form was prepared in consultation with experts and the value elements in Tunyuquq Monument were determined and then with the problem of the study, the following conclusions were reached: ?\tIn Tunyuquq Monument, about 179 value elements have been identified, directly or indirectly, including 25 different values of the Turkish nation.

    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.

Method Fifty-two of 62 male inmates of a semi-open prison (Givenich Penitentiary Centre, the only such unit in Luxembourg, and 69 LTU registered at the Luxembourg Employment Administration completed a questionnaire exploring: 1 mental health (measured by means of scales GHQ12 and CES-D; 2 employment commitment; 3 availability of a support network, self-esteem, empowerment; and 4 socio-demographic characteristics. Results Compared with LTU, inmates were younger, more had work experience (54.9% vs 26.1%, and more were educated to only a low level (71.1% vs 58.0%. The link between employment commitment and mental health in the LTU was the opposite of that seen among the prisoners: the more significant the perceived importance of employment, the worse the mental health (GHQ12 p = 0.003; CES-D p Conclusion The two groups clearly need professional support. Future research should further investigate the link between different forms of professional help and mental health. Randomized controlled trials could be carried out in both groups, with interventions to improve work commitment for prisoners and to help with getting a job for LTU. For those LTU who value employment but cannot find it, the best help may be psychological support.

    The aim of this study was to quantify pancreatic exocrine function in normal subjects and in patients with chronic pancreatitis (CP) before and after pancreatic duct drainage procedures (PDDP) with dynamic secretin-enhanced magnetic resonance (MR) cholangiopancreatography (S-MRCP). Pancreatic exocrine secretions [quantified by pancreatic flow output (PFO) and total excreted volume (TEV)] were quantified twice in ten healthy volunteers and before and after treatment in 20 CP patients (18 classified as severe, one as moderate, and one as mild according to the Cambridge classification). PFO and TEV were derived from a linear regression between MR-calculated volumes and time. In all subjects, pancreatic exocrine fluid volume initially increased linearly with time during secretin stimulation. In controls, the mean PFO and TEV were 6.8 ml/min and 97 ml; intra-individual deviations were 0.8 ml/min and 16 ml. In 10/20 patients with impaired exocrine secretions before treatment, a significant increase of PFO and TEV was observed after treatment (P<0.05); 3/20 patients presented post-procedural acute pancreatitis and a reduced PFO. The S-MRCP quantification method used in the present study is reproducible and provides normal values for PFO and TEV in the range of those obtained from previous published intubation studies. The initial results in CP patients have demonstrated non-invasively a significant short-term improvement of PFO and TEV after PDDP. (orig.)

    McMillan, John; Walker, Simon; Hope, Tony

    2014-01-01

    This article argues that hope is of value in clinical ethics and that it can be important for clinicians to be sensitive to both the risks of false hope and the importance of retaining hope. However, this sensitivity requires an understanding of the complexity of hope and how it bears on different aspects of a well-functioning doctor-patient relationship. We discuss hopefulness and distinguish it, from three different kinds of hope, or 'hopes for', and then relate these distinctions back to differing accounts of autonomy. This analysis matters because it shows how an overly narrow view of the ethical obligations of a clinician to their patient, and autonomy, might lead to scenarios where patients regret the choices they make.

  1. Fair Value or Market Value?

    Bogdan Cosmin Gomoi

    2014-12-01

    Full Text Available When taking into consideration the issue of defining the “fair value” concept, those less experimented in the area often fall in the “price trap”, which is considered as an equivalent of the fair value of financial structures. This valuation basis appears as a consequence of the trial to provide an “accurate image” by the financial statements and, also, as an opportunity for the premises offered by the activity continuing principle. The specialized literature generates ample controversies regarding the “fair value” concept and the “market value” concept. The paper aims to debate this issue, taking into account various opinions.

    2014-08-26

    Vaccination has led to remarkable health gains over the last century. However, large coverage gaps remain, which will require significant financial resources and political will to address. In recent years, a compelling line of inquiry has established the economic benefits of health, at both the individual and aggregate levels. Most existing economic evaluations of particular health interventions fail to account for this new research, leading to potentially sizable undervaluation of those interventions. In line with this new research, we set forth a framework for conceptualizing the full benefits of vaccination, including avoided medical care costs, outcome-related productivity gains, behavior-related productivity gains, community health externalities, community economic externalities, and the value of risk reduction and pure health gains. We also review literature highlighting the magnitude of these sources of benefit for different vaccinations. Finally, we outline the steps that need to be taken to implement a broad-approach economic evaluation and discuss the implications of this work for research, policy, and resource allocation for vaccine development and delivery.

    Organizations that follow the principles of good Earned Value Management (EVM) create an environment that allows teams to successfully operate and thrive ? even in the face of challenges that could negatively impact their projects. Earned Value Project Management (EVPM) is a methodology used to measure and communicate the real physical progress of a project taking into account the work completed, the time taken and the costs incurred to complete that work. As a result, EVPM allows more educated and effective management decision-making, which helps evaluate and control project risk by measuring project progress in monetary terms. In the first two editions of Earned Value Project Management, Quentin W. Fleming and Joel M.

    Full Text Available Dede Korkut Stories are unique masterpieces of Turkish culture. These stories have an important position among the works that based on expression in Turkish literature. Dede Korkut Stories have been listened and read pleasantly by Turks; because of this fact, Anatolian Turks felt a deep love and commitment against the ancestors of Oghuz. The places such as Greek Province, Georgia, Karadervent, Avnik Castle and Bayburt Fortress mentioned in the story of Bamsı Beyrek have indicated that episodes have occurred in Anatolia and at a wider context in South Caucasus. When being looked at the names of the places, it can be viewed that Dede Korkut Stories have common sounds and heritages of Caucasian people within its structure. Whether oral or written, searching Dede Korkut Stories which have a literary identity, by a variety of methods, has an importance in terms of understanding how deep meanings those stories, which are the masterworks of Turkish culture, have. These stories have both sensual dimension and a deeper multi – layer spiritual structure. In this study when in the sensual dimension the states of indicators against each other providing dramatic action have been pursued, in the deep structure the returning process of Bamsı Beyrek, protagonist of the story, back to home has been analyzed by the means of showing conflict states of values. In the study, the content of the story is tried to be interpreted by describing the phenomenons. This study aims to evaluate the story in terms of homosemiotics. Dede Korkut Hikâyeleri, Türk kültürünün eşsiz şaheserleridir. Bu hikâyeler, Türk edebiyatında anlatıma/tahkiyeye dayalı eserler arasında önemli bir konuma sahiptir. Dede Korkut Hikâyeleri, Türkler tarafından sevilerek dinlenmiş ve okunmuş; böylece ataları Oğuzlara karşı, Anadolu Türklerinin derin bir sevgi ve bağlılık duymasına vesile olmuştur.

  6. Value of Fundamental Science

    Science.gov (United States)

    Burov, Alexey

    Fundamental science is a hard, long-term human adventure that has required high devotion and social support, especially significant in our epoch of Mega-science. The measure of this devotion and this support expresses the real value of the fundamental science in public opinion. Why does fundamental science have value? What determines its strength and what endangers it? The dominant answer is that the value of science arises out of curiosity and is supported by the technological progress. Is this really a good, astute answer? When trying to attract public support, we talk about the ``mystery of the universe''. Why do these words sound so attractive? What is implied by and what is incompatible with them? More than two centuries ago, Immanuel Kant asserted an inseparable entanglement between ethics and metaphysics. Thus, we may ask: which metaphysics supports the value of scientific cognition, and which does not? Should we continue to neglect the dependence of value of pure science on metaphysics? If not, how can this issue be addressed in the public outreach? Is the public alienated by one or another message coming from the face of science? What does it mean to be politically correct in this sort of discussion?

  7. Impact of Obstructive Sleep Apnea on the Levels of Placental Growth Factor (PlGF and Their Value for Predicting Short-Term Adverse Outcomes in Patients with Acute Coronary Syndrome.

    Directory of Open Access Journals (Sweden)

    Antonia Barcelo

    Full Text Available Placental growth factor (PlGF induces angiogenesis and promotes tissue repair, and plasma PlGF levels change markedly during acute myocardial infarction (AMI. Currently, the impact of obstructive sleep apnea (OSA in patients with AMI is a subject of debate. Our objective was to evaluate the relationships between PlGF levels and both the severity of acute coronary syndrome (ACS and short-term outcomes after ACS in patients with and without OSA.A total of 538 consecutive patients (312 OSA patients and 226 controls admitted for ACS were included in this study. All patients underwent polygraphy in the first 72 hours after hospital admission. The severity of disease and short-term prognoses were evaluated during the hospitalization period. Plasma PlGF levels were measured using an electrochemiluminescence immunoassay.Patients with OSA were significantly older and more frequently hypertensive and had higher BMIs than those without OSA. After adjusting for age, smoking status, BMI and hypertension, PlGF levels were significantly elevated in patients with OSA compared with patients without OSA (19.9 pg/mL, interquartile range: 16.6-24.5 pg/mL; 18.5 pg/mL, interquartile range: 14.7-22.7 pg/mL; p1, even after adjustment.The results of this study show that in patients with ACS, elevated plasma levels of PlGF are associated with the presence of OSA and with adverse outcomes during short-term follow-up.ClinicalTrials.gov NCT01335087.

    Accumulation of phosphorus (P) in agricultural topsoils can contribute to leaching of P which may cause eutrophication of surface waters. An understanding of P mobilization processes in the plough layer is needed to improve agricultural management strategies. We compare leaching of total dissolved...... and particulate P through the plough layer of a typical Danish sandy loam soil subjected to three different P fertilizer regimes in a long-term field experiment established in 1975. The leaching experiment used intact soil columns (20cm diameter, 20cm high) during unsaturated conditions. The three soils had small...

    Policies to reduce unnecessary hospitalizations after percutaneous coronary intervention (PCI) are intended to improve healthcare value by reducing costs while maintaining patient outcomes. Whether facility-level hospitalization rates after PCI are associated with cost of care is unknown. We studied 32,080 patients who received PCI at any 1 of 62 Veterans Affairs hospitals from 2008 to 2011. We identified facility outliers for 30-day risk-standardized hospitalization, mortality, and cost. Compared with the risk-standardized average, 2 hospitals (3.2%) had a lower-than-expected hospitalization rate, and 2 hospitals (3.2%) had a higher-than-expected hospitalization rate. We observed no statistically significant variation in facility-level risk-standardized mortality. The facility-level unadjusted median per patient 30-day total cost was $23,820 (interquartile range, $19,604-$29,958). Compared with the risk-standardized average, 17 hospitals (27.4%) had lower-than-expected costs, and 14 hospitals (22.6%) had higher-than-expected costs. At the facility level, the index PCI accounted for 83.1% of the total cost (range, 60.3%-92.2%), whereas hospitalization after PCI accounted for only 5.8% (range, 2.0%-12.7%) of the 30-day total cost. Facilities with higher hospitalization rates were not more expensive (Spearman ρ=0.16; 95% confidence interval, -0.09 to 0.39; P=0.21). In this national study, hospitalizations in the 30 day after PCI accounted for only 5.8% of 30-day cost, and facility-level cost was not correlated with hospitalization rates. This challenges the focus on reducing hospitalizations after PCI as an effective means of improving healthcare value. Opportunities remain to improve PCI value by reducing the variation in total cost of PCI without compromising patient outcomes. © 2015 American Heart Association, Inc.

    The standardization for the clinical use of drug therapy for cerebral infarction (CI) has not yet determined in some aspects. In this paper, we discussed the efficacies of different drug therapies (aspirin, aspirin plus dipyridamole, aspirin plus clopidogrel, aspirin plus warfarin, cilostazol, warfarin, and ticlopidine) for CI. We searched databases of PubMed and Cochrane Library from the inception to April, 2017, randomized controlled trials (RCTs) met the inclusion and exclusion criteria were enrolled in this study. The network meta-analysis integrated evidences of direct and indirect comparisons to assess odd ratios (OR) and surface under the cumulative ranking curves (SUCRA) value. Thirteen eligible RCTs including 7 drug therapies were included into this network meta-analysis. The network meta-analysis results showed that CI patients who received aspirin plus dipyridamole presented lower mortality when compared with those received aspirin plus clopidogrel (OR = 0.46, 95% CI = 0.18-0.99), indicating aspirin plus dipyridamole therapy had better efficacy for CI. As for intracranial hemorrhage (ICH), stroke recurrence, and adverse event (AE) rate, there were no significant differences of efficacy among 7 drug therapies. Besides, SUCRA values demonstrated that in the 7 drug therapies, aspirin plus dipyridamole therapy was more effective than others (mortality: 80.67%; ICH: 76.6%; AE rate: 90.2%). Our findings revealed that aspirin plus dipyridamole therapy might be the optimum one for patients with CI, which could help to improve the survival of CI patients.

    Relative changes in B-type natriuretic peptide (BNP) and amino terminal pro-BNP (NT-proBNP) levels may help to assess the risk of congestive heart failure (CHF). However, whether these levels at the time of admission enable the prediction of outcomes with acute exacerbation remains unknown. The current study determined the abilities of BNP, NT-proBNP and their ratio to predict in-hospital and long-term outcomes of patients with CHF. Patients who were admitted to the cardiac care unit of Juntendo University Hospital (Tokyo, Japan) with acute CHF onset were consecutively enrolled into the present observational study. Serum levels of BNP and NT-proBNP were immediately measured on admission, and other biomarkers and clinical data were also investigated. Of 195 enrolled patients, 16 (8.2%) succumbed to CHF in hospital and 124 (69.3%) reached the endpoint of mortality or readmission following a median follow-up of 14 months. Multiple linear regression analysis revealed body mass index, low density lipoprotein cholesterol, hemoglobin, estimated glomerular filtration rate and C-reactive protein as independent predictors of the NT-proBNP/BNP ratio. BNP, NT-proBNP and their ratio were significantly higher among those who succumbed to CHF than in those who remained alive in hospital (P<0.05). Logistic regression analysis indicated that the ratio was an independent predictor for in-hospital mortality and long-term outcomes. In conclusion, the ratio of NT-proBNP to BNP more effectively predicts in-hospital outcomes than either factor alone and it may also help to predict outcomes among patients with acute exacerbation of HF.

  14. Use value, exchange value, and resource scarcity

    International Nuclear Information System (INIS)

    Stern, D.I.

    1999-01-01

    The literature on natural resource scarcity indicators is reviewed. Scarcity indicators can be classified by what is being measured: value of the resource stock or value of extracted resource commodities; whose value is considered: social vs. private scarcity; and by the mode of valuation considered: exchange value and use value. Prices and rents are common measures of exchange value or indicators of ''exchange scarcity'' and unit costs can be seen as use value indicators or indicators of u se scarcity . The major aim of this paper is to demonstrate the links between productivity indicators such as unit costs and the classical concept of use value. The two classes of indicator relate to John Commons' discussions of scarcity and efficiency, and a marginal vs. a non-marginal approach to value and scarcity. The classical use value concept also has wider relevance for issues of valuation in energy, resource, and environmental policy. (author)

    To investigate correlates of valuing physical attractiveness in a mate, it was hypothesized that valuing physical attractiveness in a mate would correlate with sex and valuing promiscuous sex, status, personal physical attractiveness, beauty, and order. Men and women college students completed measures of the extent to which they valued physical attractiveness in a mate and other variables. Valuing physical attractiveness in a mate was correlated with sex (men valued physical attractiveness in a mate more than did women) and valuing promiscuous sex and status, and, for women, valuing personal physical attractiveness. The results were explained in terms of evolutionary theory.

    The clinical relevance of low IGF-I levels, caused by cranial radiotherapy, in adult childhood cancer survivors has not been studied extensively. We evaluated whether IGF-I is a useful marker for altered body composition and growth hormone deficiency (GHD) in this group. We analyzed retrospective data from 610 adult childhood cancer survivors, retrieved from the late effects clinic. Median age at diagnosis was 6 years (interquartile range 3-11) and follow-up time was 18 years (13-24). We assessed IGF-I standard deviation scores (SDS), anthropometrical measures, growth hormone stimulation tests in patients with clinical signs of GHD, and measures of body composition (assessed by dual X-ray absorptiometry, Lunar Prodigy). In 58 cranially irradiated acute leukemia survivors (25 Gy (24-25)) and 56 locally irradiated brain tumor survivors (42 Gy (35-54)) we found significantly lower IGF-I SDS (P body mass index (P = 0.01), higher waist-hip ratio (WHR; P = 0.001), higher total fat percentage SDS (P body mass SDS (P body mass (r = 0.15, P = 0.01). In patients with low IGF-I levels, IGF-I did not significantly differ between subjects with and without GHD as determined by GH-stimulation testing (P = 0.39). This study shows that IGF-I has limited value as a marker for alterations in body composition in adult childhood cancer survivors. Copyright © 2011 Wiley Periodicals, Inc.

    Background: A joint analysis of data from centers involved in the Spanish Cooperative Initiative for Intraoperative Electron Radiotherapy was performed to investigate long-term outcomes of locally recurrent soft tissue sarcoma (LR-STS) patients treated with a multidisciplinary approach. Methods and Materials: Patients with a histologic diagnosis of LR-STS (extremity, 43%; trunk wall, 24%; retroperitoneum, 33%) and no distant metastases who underwent radical surgery and intraoperative electron radiation therapy (IOERT; median dose, 12.5 Gy) were considered eligible for participation in this study. In addition, 62% received external beam radiation therapy (EBRT; median dose, 50 Gy). Results: From 1986 to 2012, a total of 103 patients from 3 Spanish expert IOERT institutions were analyzed. With a median follow-up of 57 months (range, 2-311 months), 5-year local control (LC) was 60%. The 5-year IORT in-field control, disease-free survival (DFS), and overall survival were 73%, 43%, and 52%, respectively. In the multivariate analysis, no EBRT to treat the LR-STS (P=.02) and microscopically involved margin resection status (P=.04) retained significance in relation to LC. With regard to IORT in-field control, only not delivering EBRT to the LR-STS retained significance in the multivariate analysis (P=.03). Conclusion: This joint analysis revealed that surgical margin and EBRT affect LC but that, given the high risk of distant metastases, DFS remains modest. Intensified local treatment needs to be further tested in the context of more efficient concurrent, neoadjuvant, and adjuvant systemic therapy.

  19. Values beyond value? Is anything beyond the logic of capital?

    2014-03-01

    We are living in a time when it is frequently assumed that the logic of capital has subsumed every single aspect of our lives, intervening in the organization of our intimate relations as well as the control of our time, including investments in the future (e.g. via debt). The theories that document the incursion of this logic (often through the terms of neoliberalism and/or governmentality) assume that this logic is internalized, works and organizes everything including our subjectivity. These theories performatively reproduce the very conditions they describe, shrinking the domain of values and making it subject to capital's logic. All values are reduced to value. Yet values and value are always dialogic, dependent and co-constituting. In this paper I chart the history by which value eclipses values and how this shrinks our sociological imagination. By outlining the historical processes that institutionalized different organizations of the population through political economy and the social contract, producing ideas of proper personhood premised on propriety, I detail how forms of raced, gendered and classed personhood was formed. The gaps between the proper and improper generate significant contradictions that offer both opportunities to and limits on capitals' lines of flight. It is the lacks, the residues, and the excess that cannot be captured by capital's mechanisms of valuation that will be explored in order to think beyond the logic of capital and show how values will always haunt value. © London School of Economics and Political Science 2014.

    The prognostic value of rest 201 Tl/stress 99m Tc-tetrofosmin myocardial perfusion single-photon emission computed tomography (SPECT) for the prediction of future hard cardiac events, including acute myocardial infarction (AMI), unstable angina (UAP) and cardiac death, and the implications for risk stratification has not yet been defined in a Japanese population. The 1,988 patients who underwent rest 201 Tl/stress 99m Tc-tetrofosmin SPECT were identified and followed up for the occurrence of AMI, UAP and cardiac death. The mean follow-up interval was 26.9±15.8 months. The 142 patients were revascularized within 60 days after SPECT and they were censored from the prognostic analysis. Summed stress score (SSS), summed rest score and summed difference score (SDS) were calculated using a 5-point scoring (Normal: 0, No uptake: 4) and a 20-segment model; 22 cases of myocardial infarction, 31 of UAP and 22 cardiac deaths occurred (1.2%, 1.7% and 1.2%, respectively). Multivariate Cox regression analysis showed that hypertension (Wald 6.37, p<0.05) and SDS (Wald 8.77, p<0.01) were independent predictors of AMI and UAP. Advanced age (Wald 16.0, p<0.001), SSS (Wald 10.9, p<0.01) and SDS (Wald 4.58, p<0.05) were independent predictors of cardiac death. Myocardial perfusion SPECT yields prognostic information toward the identification of acute coronary syndrome and cardiac death. (author)

    By focusing on its mission values, a hospital can enhance the quality of patient care, improve staff morale, promote cost-effectiveness, and achieve a competitive advantage in the hospital marketplace. Since 1979 Saint Joseph Hospital, Kansas City, MO, has conducted a project to clarify and apply its values to the organization's overall direction and the everyday work setting. The project has proven that a concentration on mission values can benefit both the hospital's basic "spirit" and its bottom line. Twelve guiding principles are essential to creating a values-focused hospital: 1. Begin with a commitment. 2. Identify, involve, and educate "stakeholders". 3. Identify and use appropriate resources. 4. Assess organizational needs. 5. Identify the organization's values. 6. Translate mission values into everyday language. 7. Use an explicit, visible process built with a core set of process tools. 8. Document and showcase results. 9. Link the values work to the organization's overall direction and goals and to day-to-day management issues. 10. Think and act strategically. 11. Weave values focus into the fabric of the organization to ensure permanence and long-term success. 12. Model behavior on values.

  8. Indigenous environmental values as human values

    Directory of Open Access Journals (Sweden)

    Monica Gratani

    2016-12-01

    Full Text Available The claim that in natural resource management (NRM a change from anthropocentric values and ethics to eco-centric ones is necessary to achieve sustainability leads to the search for eco-centric models of relationship with the environment. Indigenous cultures can provide such models; hence, there is the need for multicultural societies to further include their values in NRM. In this article, we investigate the environmental values placed on a freshwater environment of the Wet Tropics by a community of indigenous Australians. We discuss their environmental values as human values, and so as beliefs that guide communities’ understanding of how the natural world should be viewed and treated by humans. This perspective represents a step forward in our understanding of indigenous environmental values, and a way to overcome the paradigm of indigenous values as valued biophysical attributes of the environment or processes happening in landscapes. Our results show that the participant community holds biospheric values. Restoring these values in the NRM of the Wet Tropics could contribute to sustainability and environmental justice in the area.

  9. Value and power in economics

    Directory of Open Access Journals (Sweden)

    Josifidis Kosta

    2012-01-01

    Full Text Available In this article we rethink the field of value in economic theory. First, we prove that the transhistorical and nominalist approaches show different weaknesses and can not account for the constitutive dimensions of value. Within this context, we demonstrate why value emerged in the first place and what epistemological dimensions it provided and enabled for economic reflexivity. In addition, we demonstrate that it is impossible to understand inherent value as an immanent property of goods in economic transactions and we critique the approach that renders value to the theory of price. Economic relations reflect value-related aspects without which the relations could not be understood. We then analyze the interrelations between power and value, proving the constitutive dimension of power in understanding value, demonstrated in selected examples. We treat power as a constellation in which economic agents act on other subjects to provoke certain activity. Power may occur only where the behaviour of subjects is not entirely determined. Finally, one additional selected example shows the range of this theory of power in terms of positional goods.

  15. Valuing future citizens' values regarding risk

    Valuing present citizen's values regarding the risks they face is an important aspect of risk assessment and risk acceptability. Conferences like VALDOR are held for this reason. Governments like Sweden have national referendums on various risk-prone enterprises. The results of these referendums can determine the future of these programs. In the United States, when guidelines are set for determining acceptable levels of risk, the relevant federal agencies are often required to provide a comment period regarding proposed guidelines in order to ascertain the judgments, including the weights place on certain values, of individual members of society as well as stakeholder groups. After the comment period ends, the agency decides on the acceptable level of risk, taking into account the comments from present citizens. Do we also have a duty to value the not-yet-existing values of future citizens, especially if the risks created by the activities of present citizens extend into the future to citizens not yet living? If so, are there any circumstances which entitle us to de-value those not-yet-existing values. In this paper, I ground my discussion of the question of valuing future citizens' values in one of the areas of focus of the VALDOR conference: nuclear waste management and specifically the question facing the United States' program regarding an acceptable dose standard associated with the release of radioactivity into the biosphere from an underground repository. The underlying conference theme to which this discussion may be attached is community environmental justice as it applies to future citizens. I focus on the role that uncertainty plays is providing justice between present and future citizens

  4. Valuing Our Values: Conflicts Between Principles and Practice

    International Nuclear Information System (INIS)

    Sjoelander, Annika

    2003-01-01

    The strong attendance and support for this and previous years' VALDOR symposia provides evidence of a collective vision that new approaches are required for society to meet the challenges presented by complex decisions on risk. We are all exposed to doubts about the capacity of the (late-)modern society's structures and institutions to deal with such decisions. These doubts are interwoven with an apparent distrust of specialist roles in the decision making process, not only those that are played by experts and scientists, but also the roles of politicians and journalists. In general, one can say that we try to identify sources of conflict in decisions on risk, and that we try to find a 'better' way - a way that is both holistic and truly democratic, rather than fragmented and controlled by the balance of power between competing interest groups. To sum up, we find that several of the problems associated with the practice of valuing our values can be understood, at least in general terms, in relation to the way in which questions about values are framed as well as received. Despite the fact that we appear to know exactly what we mean when we talk about transparency and values, we are not at all 'experts' in handling values, whether as senders or receivers in the communication chain. There is a need for more mature contexts when it comes to valuing our values. From our perspective, it also seems important to understand better how to frame questions about values in ways that are not threatening to the individual. And, last but not least, it is important to acknowledge and build on existing good practice within specialist roles in the risk discourse, such as ways for exposing the judgements and uncertainties that are part of risk assessment and multi-attribute analysis

  5. The relative value of growth.

    Mass, Nathaniel J

    2005-04-01

    Most executives would say that adding a point of growth and gaining a point of operating-profit margin contribute about equally to shareholder value. Margin improvements hit the bottom line immediately, while growth compounds value over time. But the reality is that the two are rarely equivalent. Growth often is far more valuable than managers think. For some companies, convincing the market that they can grow by just one additional percentage point can be worth six, seven, or even ten points of margin improvement. This article presents a new strategic metric, called the relative value of growth (RVG), which gives managers a clear picture of how growth projects and margin improvement initiatives affect shareholder value. Using basic balance sheet and income sheet data, managers can determine their companies' RVGs, as well as those of their competitors. Calculating RVGs gives managers insights into which corporate strategies are working to deliver value and whether their companies are pulling the most powerful value-creation levers. The author examines a number of well-known companies and explains what their RVG numbers say about their strategies. He reviews the unspoken assumption that growth and profits are incompatible over the long term and shows that a fair number of companies are effective at delivering both. Finally, he explains how managers can use the RVG framework to help them define strategies that balance growth and profitability at both the corporate and business unit levels.

  6. Value of credit bureau reports

    Directory of Open Access Journals (Sweden)

    Brković Milan

    2017-01-01

    Full Text Available An efficient system of credit information sharing contributes to solving the problem of information asymmetry on the credit and financial markets in general. The consequences of the global economic and financial crisis revealed an increasing demand for reliable information and data which could close the existing gap in their insufficiency, misuse or inadequate analytical value for the economic and financial policy makers. In that sense, more attention is directed to the usefulness of credit information sharing and the practical value of information and data contained in credit bureau reports for the purposes of achieving the overall economic policy goals. The fulfillment of that role depends mostly on the credit information sharing system and its characteristics, participants, and procedures. A credit bureau report in the best possible manner reflects all advantages and disadvantages of the established credit information exchange system in terms of its analytical value for the purposes of efficient macroeconomic and macrofinancial policies.

  7. Political Values or the Value of Politics

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available This essay was motivated by the gap between proclaimed democratic principles and the perceptions of politics which are exhibited by the citizens in transitional countries -more specifically in the Republic of Macedonia. It is based on research data collected in the past few decades, which illustrate that, in their political actions, the citizens are highly motivated by personal benefits and profits, rather than by their internalized values and ideologies. Non-democratic, authoritarian values prevail, while politics is perceived as a value itself, in the most materialistic meaning of the word. It creates a suitable milieu for growth of corruption, nepotism and clientelism. The authors conclude that such a circulus vitsiosus is a corner stone of the Macedonian political regime, and an enormous obstacle for the advancement of the participative, democratic political culture in reality, in spite of its formal acceptance.

  13. The forecaster's added value

    Turco, M.; Milelli, M.

    2009-09-01

    To the authors' knowledge there are relatively few studies that try to answer this topic: "Are humans able to add value to computer-generated forecasts and warnings ?". Moreover, the answers are not always positive. In particular some postprocessing method is competitive or superior to human forecast (see for instance Baars et al., 2005, Charba et al., 2002, Doswell C., 2003, Roebber et al., 1996, Sanders F., 1986). Within the alert system of ARPA Piemonte it is possible to study in an objective manner if the human forecaster is able to add value with respect to computer-generated forecasts. Every day the meteorology group of the Centro Funzionale of Regione Piemonte produces the HQPF (Human QPF) in terms of an areal average for each of the 13 regional warning areas, which have been created according to meteo-hydrological criteria. This allows the decision makers to produce an evaluation of the expected effects by comparing these HQPFs with predefined rainfall thresholds. Another important ingredient in this study is the very dense non-GTS network of rain gauges available that makes possible a high resolution verification. In this context the most useful verification approach is the measure of the QPF and HQPF skills by first converting precipitation expressed as continuous amounts into ‘‘exceedance'' categories (yes-no statements indicating whether precipitation equals or exceeds selected thresholds) and then computing the performances for each threshold. In particular in this work we compare the performances of the latest three years of QPF derived from two meteorological models COSMO-I7 (the Italian version of the COSMO Model, a mesoscale model developed in the framework of the COSMO Consortium) and IFS (the ECMWF global model) with the HQPF. In this analysis it is possible to introduce the hypothesis test developed by Hamill (1999), in which a confidence interval is calculated with the bootstrap method in order to establish the real difference between the

    We offer a formal treatment of choice behavior based on the premise that agents minimize the expected free energy of future outcomes. Crucially, the negative free energy or quality of a policy can be decomposed into extrinsic and epistemic (or intrinsic) value. Minimizing expected free energy is therefore equivalent to maximizing extrinsic value or expected utility (defined in terms of prior preferences or goals), while maximizing information gain or intrinsic value (or reducing uncertainty about the causes of valuable outcomes). The resulting scheme resolves the exploration-exploitation dilemma: Epistemic value is maximized until there is no further information gain, after which exploitation is assured through maximization of extrinsic value. This is formally consistent with the Infomax principle, generalizing formulations of active vision based upon salience (Bayesian surprise) and optimal decisions based on expected utility and risk-sensitive (Kullback-Leibler) control. Furthermore, as with previous active inference formulations of discrete (Markovian) problems, ad hoc softmax parameters become the expected (Bayes-optimal) precision of beliefs about, or confidence in, policies. This article focuses on the basic theory, illustrating the ideas with simulations. A key aspect of these simulations is the similarity between precision updates and dopaminergic discharges observed in conditioning paradigms.

  5. Overstating values: medical facts, diverse values, bioethics and values-based medicine.

    Science.gov (United States)

    Parker, Malcolm

    2013-02-01

    Fulford has argued that (1) the medical concepts illness, disease and dysfunction are inescapably evaluative terms, (2) illness is conceptually prior to disease, and (3) a model conforming to (2) has greater explanatory power and practical utility than the conventional value-free medical model. This 'reverse' model employs Hare's distinction between description and evaluation, and the sliding relationship between descriptive and evaluative meaning. Fulford's derivative 'Values Based Medicine' (VBM) readjusts the imbalance between the predominance of facts over values in medicine. VBM allegedly responds to the increased choices made available by, inter alia, the progress of medical science itself. VBM attributes appropriate status to evaluative meaning, where strong consensus about descriptive meaning is lacking. According to Fulford, quasi-legal bioethics, while it can be retained as a kind of deliberative framework, is outcome-based and pursues 'the right answer', while VBM approximates a democratic, process-oriented method for dealing with diverse values, in partnership with necessary contributions from evidence-based medicine (EBM). I support the non-cognitivist underpinnings of VBM, and its emphasis on the importance of values in medicine. But VBM overstates the complexity and diversity of values, misrepresents EBM and VBM as responses to scientific and evaluative complexity, and mistakenly depicts 'quasi-legal bioethics' as a space of settled descriptive meaning. Bioethical reasoning can expose strategies that attempt to reduce authentic values to scientific facts, illustrating that VBM provides no advantage over bioethics in delineating the connections between facts and values in medicine. © 2011 Blackwell Publishing Ltd.

    Objective The role of cost-effectiveness analysis (CEA) in incentivizing innovation is controversial. Critics of CEA argue that its use for pricing purposes disregards the ‘value of innovation’ reflected in new drug development, whereas supporters of CEA highlight that the value of innovation is already accounted for. Our objective in this article is to outline the limitations of the conventional CEA approach, while proposing an alternative method of evaluation that captures the value of innovation more accurately. Method The adoption of a new drug benefits present and future patients (with cost implications) for as long as the drug is part of clinical practice. Incidence patients and off-patent prices are identified as two key missing features preventing the conventional CEA approach from capturing 1) benefit to future patients and 2) future savings from off-patent prices. The proposed CEA approach incorporates these two features to derive the total lifetime value of an innovative drug (i.e., the value of innovation). Results The conventional CEA approach tends to underestimate the value of innovative drugs by disregarding the benefit to future patients and savings from off-patent prices. As a result, innovative drugs are underpriced, only allowing manufacturers to capture approximately 15% of the total value of innovation during the patent protection period. In addition to including the incidence population and off-patent price, the alternative approach proposes pricing new drugs by first negotiating the share of value of innovation to be appropriated by the manufacturer (>15%?) and payer (price that satisfies this condition. Conclusion We argue for a modification to the conventional CEA approach that integrates the total lifetime value of innovative drugs into CEA, by taking into account off-patent pricing and future patients. The proposed approach derives a price that allows manufacturers to capture an agreed share of this value, thereby incentivizing

    2008-03-01

    Expectancy-Value Model (EVM) is the most structured model in psychology to predict attitudes by measuring attitudinal attributes (AAs) and relevant external variables. Because health value could be categorized as attitude, we aimed to apply EVM to explore its usefulness in explaining variances in health values and investigate underlying factors. Focus group discussion was carried out to identify the most common and significant AAs toward 5 different health states (coded as 11111, 11121, 21221, 32323, and 33333 in EuroQol Five-Dimension (EQ-5D) descriptive system). AAs were measured in a sum of multiplications of subjective probability (expectancy) and perceived value of attributes with 7-point Likert scales. Health values were measured using visual analog scales (VAS, range 0-1). External variables (age, sex, ethnicity, education, housing, marital status, and concurrent chronic diseases) were also incorporated into survey questionnaire distributed by convenience sampling among eligible respondents. Univariate analyses were used to identify external variables causing significant differences in VAS. Multiple linear regression model (MLR) and hierarchical regression model were used to investigate the explanatory power of AAs and possible significant external variable(s) separately or in combination, for each individual health state and a mixed scenario of five states, respectively. Four AAs were identified, namely, "worsening your quality of life in terms of health" (WQoL), "adding a burden to your family" (BTF), "making you less independent" (MLI) and "unable to work or study" (UWS). Data were analyzed based on 232 respondents (mean [SD] age: 27.7 [15.07] years, 49.1% female). Health values varied significantly across 5 health states, ranging from 0.12 (33333) to 0.97 (11111). With no significant external variables identified, EVM explained up to 62% of the variances in health values across 5 health states. The explanatory power of 4 AAs were found to be between 13

    Recent controversy regarding the meaning and usefulness of weak values is reviewed. It is argued that in spite of recent statistical arguments by Ferrie and Combes, experiments with anomalous weak values provide useful amplification techniques for precision measurements of small effects in many realistic situations. The statistical nature of weak values is questioned. Although measuring weak values requires an ensemble, it is argued that the weak value, similarly to an eigenvalue, is a property of a single pre- and post-selected quantum system. This article is part of the themed issue `Second quantum revolution: foundational questions'.

  13. Recovery actinide values

    1979-01-01

    A process is described for partitioning and recovering actinide values from acidic waste solutions resulting from reprocessing of irradiated nuclear fuels by adding hydroxylammonium nitrate and hydrazine to the waste solution to adjust the valence of the neptunium and plutonium values in the solution to the +4 oxidation state, thus forming a feed solution and contacting the feed solution with an extractant of di-hexoxyethyl phosphoric acid in an organic diluent whereby the actinide values, most of the rare earth values and some fission product values are taken up by the extractant. Separation is achieved by contacting the loaded extractant with two aqueous strip solutions, a nitric acid solution to selectively strip the americium, curium and rare earth values and an oxalate solution of tetramethylammonium hydrogen oxalate and oxalic acid or trimethylammonium hydrogen oxalate to selectively strip the neptunium, plutonium and fission product values. Uranium values remain in the extractant and may be recovered with a phosphoric acid strip. The neptunium and plutonium values are recovered from the oxalate by adding sufficient nitric acid to destroy the complexing ability of the oxalate, forming a second feed, and contacting the second feed with a second extractant of tricaprylmethylammonium nitrate in an inert diluent whereby the neptunium and plutonium values are selectively extracted. The values are recovered from the extractant with formic acid. (author)

    Enterprise and Solution Architecture are key in today’s business environment. It is surprising that the foundation and business case for these activities are nonexistent; the financial value for the business of these activities is largely undetermined. To determine business value of enterprise and solution architecture, this thesis shows how to measure and quantify, in business terms, the value of enterprise architecture-based on business transformation and the value of solution architecture.

  16. Closing the value gap

    International Nuclear Information System (INIS)

    Snyder, A.V.

    1992-01-01

    It's a predicament. For the most part, investor-owned electric utilities trade at a deep discount to the actual (that is, replacement-cost) value to their assets. That's because most utilities fail to earn real returns large enough to justify raising and investing capital. The result is a value gap, where overall market value is significantly lower than the replacement costs of the assets. This gap is wider for utilities than for virtually any other industry in our economy. In addition to providing education and awareness, senior management must determine which businesses and activities create value and which diminish it. Then, management must allocate capital and human resources appropriately, holding down investments in value-diminishing areas until they can improve their profitability, and aggressively investing in value-enhancing businesses while preserving their profitability. But value management must not stop with resource-allocation decisions. To create a lasting transition to a value management philosophy, the utility's compensation system must also change: executives will have motivation to create value when compensation stems from this goal, not from such misleading accounting measures as earnings-per-share growth or ROE. That requires clear value-creation goals, and the organization must continuously evaluate top management's performance in light of the progress made toward those goals

    A profession's values guide daily practice and professional behaviours. They clarify what professionalism means to a profession, by providing insight into the values that members of the profession aim to uphold and profess. There has been limited research into the values of the Australian physiotherapy profession, and as such, the values that guide practice and constitute professionalism are not explicit. This study aimed to make a preliminary identification of the values of the profession, by exploring the shared professional values of 14 Australian physiotherapists. This study was guided by a qualitative approach and constructivist paradigm. Purposive sampling was employed to identify physiotherapists who could contribute rich information to the study. Semi-structured interviews were conducted and analysed using an inductive data analysis method. The emerging professional values formed three main themes. The first theme, 'the patient and the patient-therapist partnership', incorporated values such as having patient trust and working collaboratively with patients. The theme labelled 'physiotherapy knowledge, skills and practice' included the values of having an evidence base and respecting professional boundaries. The last theme, 'altruistic values', was inclusive of values such as honesty, empathy and caring. The values that emerged went beyond philanthropic values, to values that guided every day practice, professional relationships and the responsibilities of being a professional. The results contribute to research orientated towards identifying the values of the profession and in doing so, clarifying what professionalism means to the Australian physiotherapy profession. Differences between the values identified by the American Physical Therapy Association and the study reported in this paper highlight the importance of identifying the values of the profession within the Australian context. In terms of practice implications, physiotherapists may be prompted to

    Horowitz, Mardi J

    2009-12-01

    As psychoanalysts, we sometimes seem to regard values as radioactive materials that must be handled with heavy lead gloves. But the gloves should not be so thick that they interfere with the goal of sorting out values. Reasons for our hesitation to deal with issues related to values may include real disagreements with the morals of a patient, a fear of evoking unproductive and negative emotional states, and our own unresolved conflicts about value dilemmas. Psychoanalytic technique should at times include clear verbal statements of values. By being explicit about what is often implicit, we can help our patients in their work of ameliorating harsh, primitive, and critical attitudes and to self-own rules, principles, and codes of conduct. A patient with reprioritized personal values may then function with heightened interpersonal compassion, kindness, and cooperation, gaining in return love, intimacy, respect, and self-esteem.

    2015-01-01

    Neural correlates of value have been extensively reported in a diverse set of brain regions. However, in many cases it is difficult to determine whether a particular neural response pattern corresponds to a value-signal per se as opposed to an array of alternative non-value related processes, such as outcome-identity coding, informational coding, encoding of autonomic and skeletomotor consequences, alongside previously described “salience” or “attentional” effects. Here, I review a number of experimental manipulations that can be used to test for value, and I identify the challenges in ascertaining whether a particular neural response is or is not a value signal. Finally, I emphasize that some non-value related signals may be especially informative as a means of providing insight into the nature of the decision-making related computations that are being implemented in a particular brain region.

    Full Text Available This paper deals with the importance of values ​​in business development. The authors remind M. Weber and his study about the impact of Protestantism on business development. After defining the concept of value, attention is focused on the theory of R.K. Merton, T. Parsons, R. Inglehart. Using the critical sociological approach the authors reflect on the research strategies in the area of values. In this context is mentioned for example the issue of ideal and real cultures – ideal cultures consist of norms and values to which people officially claim, e.g. values of Christian civilization, values of Central Europe; so-called universal values are very often (or should be a base for legal norms. Real cultures represent a pattern according to which people act and regard it socially acceptable. In this context is also discussed the question of individualism without responsibility that is typical for current western society as well as for the Czech society of last decades. Value orientations are patterns for expected roles, culturally defined types of human relations, expressing the basic attitudes in social interaction. The level of prevailing business values is visible also in many multinational corporations espousing the concept of corporate social responsibility within their promotion but violating it in reality.

    The conventional premise that metrology is a "non-value-added necessary evil" is a misleading and dangerous assertion, which must be viewed as obsolete thinking. Many metrology applications are key enablers to traditionally labeled "value-added" processing steps in lithography and etch, such that they can be considered integral parts of the processes. Various key trends in modern, state-of-the-art processing such as optical proximity correction (OPC), design for manufacturability (DFM), and advanced process control (APC) are based, at their hearts, on the assumption of fine-tuned metrology, in terms of uncertainty and accuracy. These trends are vehicles where metrology thus has large opportunities to create value through the engineering of tight and targetable process distributions. Such distributions make possible predictability in speed-sorts and in other parameters, which results in high-end product. Additionally, significant reliance has also been placed on defect metrology to predict, improve, and reduce yield variability. The necessary quality metrology is strongly influenced by not only the choice of equipment, but also the quality application of these tools in a production environment. The ultimate value added by metrology is a result of quality tools run by a quality metrology team using quality practices. This paper will explore the relationships among present and future trends and challenges in metrology, including equipment, key applications, and metrology deployment in the manufacturing flow. Of key importance are metrology personnel, with their expertise, practices, and metrics in achieving and maintaining the required level of metrology performance, including where precision, matching, and accuracy fit into these considerations. The value of metrology will be demonstrated to have shifted to "key enabler of large revenues," debunking the out-of-date premise that metrology is "non-value-added." Examples used will be from critical dimension (CD

  8. CREATING VALUE WITHIN CONSUMPTION CULTURE

    Directory of Open Access Journals (Sweden)

    Daniel Adrian Gârdan

    2016-12-01

    Full Text Available The issue of culture consumption is a particular concern within the modern marketing theory. Culture can be seen as representing a body of knowledge, beliefs, values, attitudes, symbols etc, developed in a certain period of time by a group of individuals, items transmitted with the help of a social learning process to other generations within the group. Thus, the consumption of culture will identify itself with the consumption of any product, service or a combination of them, directly resulted as manifestation of culture, expressions of artistic creativity specific for a certain cultural space. The present paper proposes the analysis of the phenomenon referring to the culture consumption in terms of specific characteristics. The paper reviews the features specific to the modern consumer of culture, the relationship that exists between the individuals’ level of education and the culture consumption and value creation process or augmentation of the intrinsic value of an artistic product as a result of the contribution that the culture consumer can bring himself. The authors highlight the fact that within extremely complex processes which are defining the culture consumption, consumers can assume an active role, becoming on their turn co-participants in the cultural goods and services value creation and transmission. The modern consumer benefits more than ever from the advantages offered by the information technology, being called to respond to major challenges of the postmodernism paradigm in terms of culture consumption. Globalization and other social economic and politic phenomena have profoundly changed the reports between individual and culture, between self and other members of the society, causing synthesis and essential transformations of culture consumption, of culture consumers typologies, and not least of the very forms of artistic expression related to cultural goods and services.

  12. Values in dialogic pedagogy

    Directory of Open Access Journals (Sweden)

    Eugene Matusov

    2015-02-01

    Full Text Available In November 2014 on the Dialogic Pedagogy Journal Facebook page, there was an interesting discussion of the issue of values in dialogic pedagogy[1]. The main issue can be characterized as the following. Should dialogic pedagogy teach values? Should it avoid teaching values? Is there some kind of a third approach? The participants of the Facebook discussions were focusing on teaching values in dialogic pedagogy and not about teaching aboutvalues. On the one hand, it seems to be impossible to avoid teaching values. However, on the other hand, shaping students in some preset molding is apparently non-dialogic and uncritical (Matusov, 2009. In the former case, successful teaching is defined by how well and deeply the students accept and commit to the taught values. In the latter case, successful dialogic teaching may be defined by students’ critical examination of their own values against alternative values in a critical dialogue. Below, Eugene Matusov and Jay Lemke, active participants of this Facebook dialogue, provide their reflection on this important issue and encourage readers to join their reflective dialogue.[1] See in a public Facebook domain: https://www.facebook.com/DialogicPedagogyJournal/posts/894734337204533, https://www.facebook.com/DialogicPedagogyJournal/posts/896916850319615

    CERN Document Server

    Bolc, Leonard

    1992-01-01

    Many-valued logics were developed as an attempt to handle philosophical doubts about the "law of excluded middle" in classical logic. The first many-valued formal systems were developed by J. Lukasiewicz in Poland and E.Post in the U.S.A. in the 1920s, and since then the field has expanded dramatically as the applicability of the systems to other philosophical and semantic problems was recognized. Intuitionisticlogic, for example, arose from deep problems in the foundations of mathematics. Fuzzy logics, approximation logics, and probability logics all address questions that classical logic alone cannot answer. All these interpretations of many-valued calculi motivate specific formal systems thatallow detailed mathematical treatment. In this volume, the authors are concerned with finite-valued logics, and especially with three-valued logical calculi. Matrix constructions, axiomatizations of propositional and predicate calculi, syntax, semantic structures, and methodology are discussed. Separate chapters deal w...

  4. Professional values, aesthetic values, and the ends of trade.

    Science.gov (United States)

    Edgar, Andrew

    2011-05-01

    Professionalism is initially understood as a historical process, through which certain commercial services sought to improve their social status (and economic reward) by separating themselves from mere crafts or trades. This process may be traced clearly with the aspiration of British portrait painters (headed by Sir Joshua Reynolds), in the eighteenth century, to acquire a social status akin to that of already established professionals, such as clerics and doctors. This may be understood, to a significant degree, as a process of gentrification. The values of the professional thereby lie as much in the etiquette and other social skills with which they deal with their clients, than with any distinctive form of skill or value. Professionalisation as gentrification seemingly says little about the nature of modern professionalism. However, if this process is also construed as one in which the goals and achievements of the profession come to be subject to radical reflection, then something significant about professional values emerges. On this account, the profession is distinguished from craft or trade on the grounds that the goals of the profession, and the effectiveness of any attempt to realise them, are not transparent to the client. While a lay person will typically have the competence necessary to judge whether or not a craft worker has achieved their goal, that person will not necessarily be able to recognise the values that determine the success of a medical operation. It will be concluded that the values of a profession are articulated intrinsically to the profession, in terms of the contested understanding that the professionals themselves have of the meaning of the profession and the narratives within which its history is to be told.

    In this paper, the author presents a new method for finding identities for hypergeoemtric series, such as the (Gauss) hypergeometric series, the generalized hypergeometric series and the Appell-Lauricella hypergeometric series. Furthermore, using this method, the author gets identities for the hypergeometric series F(a,b;c;x) and shows that values of F(a,b;c;x) at some points x can be expressed in terms of gamma functions, together with certain elementary functions. The author tabulates the values of F(a,b;c;x) that can be obtained with this method and finds that this set includes almost all previously known values and many previously unknown values.

    We present a perturbative approach to include tensor terms in the Gogny interaction. We do not change the values of the usual parameterisations, with the only exception of the spin-orbit term, and we add tensor terms whose only free parameters are the strengths of the interactions. We identify observables sensitive to the presence of the tensor force in Hartree-Fock, Hartree-Fock-Bogoliubov and random phase approximation calculations. We show the need of including two tensor contributions, at least: a pure tensor term and a tensor-isospin term. We show results relevant for the inclusion of the tensor term for single-particle energies, charge-conserving magnetic excitations and Gamow-Teller excitations. (orig.)

We reconcile the two approaches by introducing risk aversion and utility maximization. We show that if the aggregate consumption ...

    Harmonization of certified values in Reference Materials (RMs) can be carried out by applying nuclear analytical techniques to RMs of various matrix types and concentration levels. Although RMs generally should not be used as primary standards the cross evaluation of concentrations in RMs leads to better compatibility of reference values and thus to a greater agreement between analytical results from different laboratories using these RMs for instrument calibration and quality assurance.

    Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

    Full Text Available Value Creation Reporting: Answering the Question ‘Value to Whom’ according to the International Integrated Reporting Framework The principal function of integrated reporting is the reporting of value and this phenomenon seems the most philosophical part of the International Framework. This paper discusses what the value concept refers to in the Framework: Value to investors, value to society or value to present and future generations? In this sense, we try to answer this question by highlighting the dynamics of capital formations according to interrelations between capitals and demonstrating the value creation process in the short, medium, and longer term. We show that (1 „profit” is the result of short term value creation, which indicates the „value to value chain stakeholders”, (2 „expected fair value of equity” represents the „value to investors” and (3 „longer term value” represents the „value to society” according to the International Framework. Additionally, we touch on the inadequacies of the current Framework and suggest future research opportunities within the scope of value creation reporting. To our knowledge, this study is the first to provide a detailed framework on the dynamics of capitals usage and it attempts to show the intersection of accounting and finance in terms of value creation reporting.

    2008-10-01

    Full Text Available The seminal propositions by Modigliani and Miller started a new study area in modern finance theory. Over time, their basic assumptions were relaxed, to the extent that, nowadays, situations in which they can be fully applied, with consistent and satisfactory results, are rare. On the other hand, as this simple set of propositions became known worldwide and was easily applicable, it was adopted as a rule of thumb for general enterprise valuation. However, in situations without methodological bias, the resulting enterprise values obtained by traditional methodologies are abstruse and do not allow for the analysis and management of the individual values that make up the firm and own capital values. In order to avoid this kind of abstruseness in company valuation, this study theoretically deducts an alternative valuation methodology, which permits the identification of assets’ value independently of their financing; moreover, we identify the gain on debt value that the debt provides to the shareholders, the debt tax shield and the value loss of assets and tax shield due to the increase in shareholder risk because of the leverage capital structure.

  6. Anomalous vacuum expectation values

    International Nuclear Information System (INIS)

    Suzuki, H.

    1986-01-01

    The anomalous vacuum expectation value is defined as the expectation value of a quantity that vanishes by means of the field equations. Although this value is expected to vanish in quantum systems, regularization in general produces a finite value of this quantity. Calculation of this anomalous vacuum expectation value can be carried out in the general framework of field theory. The result is derived by subtraction of divergences and by zeta-function regularization. Various anomalies are included in these anomalous vacuum expectation values. This method is useful for deriving not only the conformal, chiral, and gravitational anomalies but also the supercurrent anomaly. The supercurrent anomaly is obtained in the case of N = 1 supersymmetric Yang-Mills theory in four, six, and ten dimensions. The original form of the energy-momentum tensor and the supercurrent have anomalies in their conservation laws. But the modification of these quantities to be equivalent to the original one on-shell causes no anomaly in their conservation laws and gives rise to anomalous traces

  7. The Economic Value of Water

    Directory of Open Access Journals (Sweden)

    Pedro Arrojo Agudo

    1999-10-01

    Full Text Available The economic term of water is seen from the perspective of an ecological economy, an Aristotelian sense that integrates social values, environmental considerations and financial issues. Water should thus be conceptualized as an “ecosocial” good and not merely as a simple factor of production. Therefore, the focus of water management should not limit itself to managing a scarce resource. Rather the focus should be to articulate an institutional framework that would allow for the use of management tools based on the financial value of water (pricing policies, fiscal incentives, economic penalties for inefficiency... fixed to a somewhat interventionist market, or which answers to administration mechanisms, with constraints setting the conditions of sustainablity that the sound management of water requires in each territory. This approach brings to the table a profoundly territorial andcontextualized view of water management within the paradigm of Sustainable Development. Having said this does not imply disregarding the classical economic science tools of cost/benefit analysis, though. Quite the contrary: today, economic science can provide highly useful, multiple concepts and traditional techniques to the creation of a new model of the economic management of water. At bottom, the challenge is to take advantage of the previous conceptual and methodological body of work, refining the work in some cases,contextualizing it in others, and above all, complementing the previous work with other value-based perspectives to develop a multi-criteria decision-making model for the management and financial assessment of water policies.

  8. 10 ways to create shareholder value.

    Science.gov (United States)

    Rappaport, Alfred

    2006-09-01

    Executives have developed tunnel vision in their pursuit of shareholder value, focusing on short-term performance at the expense of investing in long-term growth. It's time to broaden that perspective and begin shaping business strategies in light of the competitive landscape, not the shareholder list. In this article, Alfred Rappaport offers ten basic principles to help executives create lasting shareholder value. For starters, companies should not manage earnings or provide earnings guidance; those that fail to embrace this first principle of shareholder value will almost certainly be unable to follow the rest. Additionally, leaders should make strategic decisions and acquisitions and carry assets that maximize expected value, even if near-term earnings are negatively affected as a result. During times when there are no credible value-creating opportunities to invest in the business, companies should avoid using excess cash to make investments that look good on the surface but might end up destroying value, such as ill-advised, overpriced acquisitions. It would be better to return the cash to shareholders in the form of dividends and buybacks. Rappaport also offers guidelines for establishing effective pay incentives at every level of management; emphasizes that senior executives need to lay their wealth on the line just as shareholders do; and urges companies to embrace full disclosure, an antidote to short-term earnings obsession that serves to lessen investor uncertainty, which could reduce the cost of capital and increase the share price. The author notes that a few types of companies--high-tech start-ups, for example, and severely capital-constrained organizations--cannot afford to ignore market pressures for short-term performance. Most companies with a sound, well-executed business model, however, could better realize their potential for creating shareholder value by adopting the ten principles.

  13. Values in Time Discounting.

    Science.gov (United States)

    Heilmann, Conrad

    2017-10-01

    Controversies about time discounting loom large in decisions about climate change. Prominently, a particularly controversial debate about time discounting in climate change decision-making has been conducted within climate economics, between the authors of Stern et al. (Stern review on the economics of climate change, 2006) and their critics (most prominently Dasgupta in Comments on the Stern review's economics of climate change, 2006; Tol in Energy Environ 17(6):977-981, 2006; Weitzman in J Econ Lit XLV:703-724, 2007; Nordhaus in J Econ Lit XLV:686-702, 2007). The article examines the role of values in this debate. Firstly, it is shown that time discounting is a case in which values are key because it is at heart an ethical problem. Secondly, it is argued that time discounting in climate economics is a case of economists making frequent and routine references to ethical values and indeed conduct ethical debates with each other. Thirdly, it is argued that there is evidence for deep and pervasive entanglement between facts and values in the prevalent methodologies for time discounting. Finally, it is argued that this means that economists have given up the 'value-free ideal' concerning time discounting, and discussed how the current methodology of time discounting in economics can be improved.

    2001-01-01

    For more than 30 years, the author has studied the model-theoretic aspects of the theory of valued fields and multi-valued fields. Many of the key results included in this book were obtained by the author whilst preparing the manuscript. Thus the unique overview of the theory, as developed in the book, has been previously unavailable. The book deals with the theory of valued fields and mutli-valued fields. The theory of Prüfer rings is discussed from the `geometric' point of view. The author shows that by introducing the Zariski topology on families of valuation rings, it is possible to distinguish two important subfamilies of Prüfer rings that correspond to Boolean and near Boolean families of valuation rings. Also, algebraic and model-theoretic properties of multi-valued fields with near Boolean families of valuation rings satisfying the local-global principle are studied. It is important that this principle is elementary, i.e., it can be expressed in the language of predicate calculus. The most important...

    What are the targets and criteria on which national energy policy should be based. What priorities should be set, and how can different social interests be matched. To answer these questions, a new instrument of decision theory is presented which has been applied with good results to controversial political issues in the USA. The new technique is known under the name of value tree analysis. Members of important West German organisations (BDI, VDI, RWE, the Catholic and Protestant Church, Deutscher Naturschutzring, and ecological research institutions) were asked about the goals of their organisations. These goals were then ordered systematically and arranged in a hierarchical tree structure. The value trees of different groups can be combined into a catalogue of social criteria of acceptability and policy assessment. The authors describe the philosophy and methodology of value tree analysis and give an outline of its application in the development of a socially acceptable energy policy. (orig.) [de

  3. R-values

    International Nuclear Information System (INIS)

    Roberts, K.

    2009-01-01

    I'll try to keep this short and simple. R LANL = (beta cpm of X exp on system 'A')/ (beta cpm of 99 Mo exp on system 'A')/ (beta cpm of X on system 'A', from thermal on 235 U)/ (beta cpm of 99 Mo on system 'A', from thermal on 235 U). As I understand it, the above equation is the historical (as well as current) way of determining R-values using data from beta counting at LANL. The ratio in the denominator, a little 'r', is the 'baseline' or 'calibration' value for a specific beta detector. Over time, if the detector 'drifts' one would see a variation in this 'r' during a thermal calibration measurement. This baseline is what LANL likes to track to monitor specific detector performance - this is not relevant to LLNL where gamma detection is used for determining R-values. LANL states that uncertainty is only dependent upon the count statistics for the isotopes measured. If one tries to convert this to an atom basis, the uncertainties will increase due to the incorporation of the uncertainties in the nuclear data used to convert the cpm to atoms. LLNL switched to gamma detection methods in the 1970s thus replacing our beta counting effort. The equation below is how we have since determined R-values. The numerator ratios atom values of isotopes that are determined by measuring gamma cpm (usually? using several peaks per isotope) and then converting to particle decay in dpm using detector efficiency for each peak and the appropriate branch ratio for each gamma emission. Isotope decay is then converted to atoms using specific activity, mass or volume?, and Avogadro's number. The denominator is simply the ratio of published, cumulative fission product chain yields for isotopes produced in a thermal irradiation on 235U - values of England and Ryder are used by LLNL for the NTNF program. Uncertainties in LLNL R-values are dependent upon gamma counting statistics as well as the nuclear data for each isotope. R LLNL = (Atoms of X exp )/(Atoms of 99 Mo exp )/(Cumulative

  5. Implementing Target Value Design.

    Alves, Thais da C L; Lichtig, Will; Rybkowski, Zofia K

    2017-04-01

    An alternative to the traditional way of designing projects is the process of target value design (TVD), which takes different departure points to start the design process. The TVD process starts with the client defining an allowable cost that needs to be met by the design and construction teams. An expected cost in the TVD process is defined through multiple interactions between multiple stakeholders who define wishes and others who define ways of achieving these wishes. Finally, a target cost is defined based on the expected profit the design and construction teams are expecting to make. TVD follows a series of continuous improvement efforts aimed at reaching the desired goals for the project and its associated target value cost. The process takes advantage of rapid cycles of suggestions, analyses, and implementation that starts with the definition of value for the client. In the traditional design process, the goal is to identify user preferences and find solutions that meet the needs of the client's expressed preferences. In the lean design process, the goal is to educate users about their values and advocate for a better facility over the long run; this way owners can help contractors and designers to identify better solutions. This article aims to inform the healthcare community about tools and techniques commonly used during the TVD process and how they can be used to educate and support project participants in developing better solutions to meet their needs now as well as in the future.

Substantial evidence shows that people who place a relatively high priority on materialistic values/goals consume more products and incur more debt, have lower-quality interpersonal relationships, act in more ecologically destructive ways, have adverse work and educational motivation, and report lower personal and physical well-being. Experimentally activating materialistic aims causes similar outcomes. Given these ills, researchers have investigated means of decreasing people's materialism. Successful interventions encourage intrinsic/self-transcendent values/goals, increase felt personal security, and/or block materialistic messages from the environment. These interventions would likely be more effective if policies were also adopted that diminished contemporary culture's focus on consumption, profit, and economic growth.

    Stanković Ljiljana

    2009-01-01

    Full Text Available The complexity of business environment imposes the need for continuous change and reexamination of business marketing strategies of enterprises. Theory and practice of strategic management and marketing show that the activities of marketing, which are closely connected to corporate strategy, are the key drivers of growth. There is a positive correlation between competition intensity, marketing strategy and business performance of companies. Even though, managers of many companies don't see a clear connection between marketing strategy and business performance, numerous empirical research show that the companies which possess and efficiently use marketing resources and capabilities are more successful. In knowledge-based economics, the development of value oriented marketing strategies for all participants in the chain is a supposition of the survival, growth and development of companies. Competitive advantage is the essence of any strategy. Acquisition and maintenance of competitive advantage is more successful if the potentials for value creation are used efficiently. The paper examines the critical factors that influence alignment and transformation of marketing strategies in accordance with changes in value estimation. Superior value, is created in different network classes. Theory and practice researches create a reliable basis for the development of new concepts, marketing strategy business models that will contribute to competitive advantage of enterprises and the economy.

  18. Radiology's value chain.

    Science.gov (United States)

    Enzmann, Dieter R

    2012-04-01

    A diagnostic radiology value chain is constructed to define its main components, all of which are vulnerable to change, because digitization has caused disaggregation of the chain. Some components afford opportunities to improve productivity, some add value, while some face outsourcing to lower labor cost and to information technology substitutes, raising commoditization risks. Digital image information, because it can be competitive at smaller economies of scale, allows faster, differential rates of technological innovation of components, initiating a centralization-to-decentralization technology trend. Digitization, having triggered disaggregation of radiology's professional service model, may soon usher in an information business model. This means moving from a mind-set of "reading images" to an orientation of creating and organizing information for greater accuracy, faster speed, and lower cost in medical decision making. Information businesses view value chain investments differently than do small professional services. In the former model, producing a better business product will extend image interpretation beyond a radiologist's personal fund of knowledge to encompass expanding external imaging databases. A follow-on expansion with integration of image and molecular information into a report will offer new value in medical decision making. Improved interpretation plus new integration will enrich and diversify radiology's key service products, the report and consultation. A more robust, information-rich report derived from a "systems" and "computational" radiology approach will be facilitated by a transition from a professional service to an information business. Under health care reform, radiology will transition its emphasis from volume to greater value. Radiology's future brightens with the adoption of a philosophy of offering information rather than "reads" for decision making. Staunchly defending the status quo via turf wars is unlikely to constitute a

  20. Value in assessing new vaccines

    Directory of Open Access Journals (Sweden)

    Giuseppe La Torre

    2009-09-01

    Full Text Available Vaccination strategies are recognised as one of the most powerful interventions in the field of Public health worldwide, capable of reducing both morbidity and mortality. There is wide availability of new vaccines, at least in Developed Countries, that have the potential to control infectious diseases, while on the other hand there are new vaccines that will become available in the next few years. This paper aims to describe the different perspectives one could take into account in valuing particularly new vaccines. The epidemiological approach has been one of underlying principles in setting priorities for immunization programs. The introduction in the health market of a new vaccine is based on the assessment of the related burden of infection/disease and the consequent impact on population health. In the economic evaluation approach several types of analysis are available. The budget impact analysis is concerned more with the immediate impact; in this sense cost is considered instead of value as well as giving higher consideration to short-term effects, while cost-effectiveness or cost-utility analysis can be utilised to examine effects in the long term. In the field of vaccinations a public approach through the use of media campaigns or non-profit organisations, might or might not push politicians and physicians to take action to address a perceived health problem via a vaccine. A Health Technology Assessment approach has been developed in some European countries to examine, in a multidisciplinary way, the clinical, economic, organizational, ethical, juridical, social and cultural implications of the introduction or the implementation of a specific technology. The HTA approach in Italy was demonstrated to be a comprehensive tool in assessing the introduction of a new vaccine, giving insight to the issue to several stakeholders, i.e. decision makers, researchers, and patients.

  2. Rights and Intentions in Value Modeling

    Science.gov (United States)

    Johannesson, Paul; Bergholtz, Maria

    In order to manage increasingly complex business and IT environments, organizations need effective instruments for representing and understanding this complexity. Essential among these instruments are enterprise models, i.e. computational representations of the structure, processes, information, resources, and intentions of organizations. One important class of enterprise models are value models, which focus on the business motivations and intentions behind business processes and describe them in terms of high level notions like actors, resources, and value exchanges. The essence of these value exchanges is often taken to be an ownership transfer. However, some value exchanges cannot be analyzed in this way, e.g. the use of a service does not influence ownership. The goal of this chapter is to offer an analysis of the notion of value exchanges, based on Hohfeld's classification of rights, and to propose notation and practical modeling guidelines that make use of this analysis.

  3. The total value equation: a suggested framework for understanding value creation in diagnostic radiology.

    Science.gov (United States)

    Heller, Richard E

    2014-01-01

    As a result of macroeconomic forces necessitating fundamental changes in health care delivery systems, value has become a popular term in the medical industry. Much has been written recently about the idea of value as it relates to health care services in general and the practice of radiology in particular. Of course, cost, value, and cost-effectiveness are not new topics of conversation in radiology. Not only is value one of the most frequently used and complex words in management, entire classes in business school are taught around the concept of understanding and maximizing value. But what is value, and when speaking of value creation strategies, what is it exactly that is meant? For the leader of a radiology department, either private or academic, value creation is a core function. This article provides a deeper examination of what value is, what drives value creation, and how practices and departments can evaluate their own value creation efficiencies. An equation, referred to as the Total Value Equation, is presented as a framework to assess value creation activities and strategies. Copyright © 2014 American College of Radiology.

    2012-07-01

    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

  18. Valuing diversity in energy supply

    International Nuclear Information System (INIS)

    Skea, Jim

    2010-01-01

    There is renewed interest in the role of supply diversity in promoting energy security. This paper explores ways of valuing diversity. A possible incentive mechanism for promoting diversity which takes account of underlying 'disparities' between different technology options is developed. The mechanism provides a way of trading off cost and diversity and results in an 'efficient' cost-diversity frontier by analogy with financial portfolio theory. If all technologies are believed to be equally disparate, the appropriate mechanism is a 'levy' imposed on market share. If the technologies are not equally disparate, the levy needs to be adjusted by technology-specific multipliers that take account of levels of disparity and patterns of market share. The analysis is applied to two stylised situations. In the long-run equilibrium case, the implications of both different patterns of disparity and different values attached to diversity are investigated. The paper also explores the implications of applying such a mechanism to the current Great Britain electricity system. The implications in terms of financial flows, for both the market as a whole and for individual operators, are investigated. Finally, the appropriateness of such a mechanism in the light of other policy goals, and possible future research directions, is discussed. (author)

    Full Text Available In addition to its intrinsic value (nature working as it is; species are the product of a long history of continuing evolution by means of ecological processes, and so they have the right to continued existence, biodiversity also plays a fundamental role as ecosystem services in the maintenance of natural ecological processes. The economic or utilitarian values of biodiversity rely upon the dependence of man on biodiversity; products that nature can provide: wood, food, fibers to make paper, resins, chemical organic products, genes as well as knowledge for biotechnology, including medicine and cosmetic sub-products. It also encompasses ecosystem services, such as climate regulation, reproductive and feeding habitats for commercial fish, some organisms that can create soil fertility through complex cycles and interactions, such as earthworms, termites and bacteria, in addition to fungi responsible for cycling nutrients like nitrogen, phosphorus and sulfur and making them available to plant absorption. These services are the benefits that people indirectly receive from natural ecosystem functions (air quality maintenance, regional climate, water quality, nutrient cycling, reproductive habitats of commercial fish, etc. with their related economic values.

    2009-01-01

    This paper analyzes the Generic Clearance Values established for natural and artificial radionuclides with the objective of evaluating their degree of conservatism in views of adopting them into the regulatory body. Generic clearance values for natural radionuclides have been chosen by experts judgments as the optimum boundary between, on one hand, the ubiquitous unmodified soil concentrations and, on the other hand, activity concentrations in ores, mineral sands, industrial residues and wastes. For artificial radionuclides the clearance levels have been derived from the scenarios postulated in the document 'Safety Reports Series Nr 44' of the IAEA considering quantitative exemption criteria. A set of 8 scenarios were postulated covering external, ingestion and inhalation exposure pathways. For each radionuclide, the generic clearance level was derived as the more restrictive value obtained from the scenarios, that is the lowest ratio between the applicable individual dose and the dose per unit activity concentration (Bq/g). The individual dose was calculated by a formula depending on each scenario and pathway, with different parameters, such as exposure time, dosimetric factors, dilution factor, density of the material, geometric factors, etc. It was concluded that the basis and parameters used for the derivation of the generic clearance levels are quite conservative and therefore its the adoption in Argentina has been recommended. It is expected that their implementation will contribute to optimize the regulatory management system. (author)

    Advancements in next-generation sequencing have greatly enhanced the development of biomarker-driven cancer therapies. The affordability and availability of next-generation sequencers have allowed for the commercialization of next-generation sequencing platforms that have found widespread use for clinical-decision making and research purposes. Despite the greater availability of tumor molecular profiling by next-generation sequencing at our doorsteps, the achievement of value-based care, or improving patient outcomes while reducing overall costs or risks, in the era of precision oncology remains a looming challenge. In this review, we highlight available data through a pre-established and conceptualized framework for evaluating value-based medicine to assess the cost (efficiency), clinical benefit (effectiveness), and toxicity (safety) of genomic profiling in cancer care. We also provide perspectives on future directions of next-generation sequencing from targeted panels to whole-exome or whole-genome sequencing and describe potential strategies needed to attain value-based genomics.

  7. Value Encounters - Modeling and Analyzing Co-creation of Value

    Science.gov (United States)

    Weigand, Hans

    Recent marketing and management literature has introduced the concept of co-creation of value. Current value modeling approaches such as e3-value focus on the exchange of value rather than co-creation. In this paper, an extension to e3-value is proposed in the form of a “value encounter”. Value encounters are defined as interaction spaces where a group of actors meet and derive value by each one bringing in some of its own resources. They can be analyzed from multiple strategic perspectives, including knowledge management, social network management and operational management. Value encounter modeling can be instrumental in the context of service analysis and design.

    Occupational injuries, accidents, trips of equipment, emergencies, and idle times represent a loss from each megawatt hour which we could have supplied to the network, or other costs related to settlement or compensation for damages. All of it can be caused by short lack of attention while doing a routine job, ignoring safety indicators, and rules. Such behaviour would not be a characteristic of a professional. People working at the nuclear power plants are the first ones to learn about the Values and Behaviour Model. (author)

    The Community Solar Value Project (CSVP) is designed to assist electric utilities in designing better community solar programs. Better programs seek new sources of value to promote “win-win” solutions between utilities and their customers. The CSVP focused on five “challenge areas” in identifying new sources of value: - Strategic solar design for community solar projects (including technology choices, siting, orientation, and related issues) - Market research and targeted marketing approaches (for program design and for customer recruitment) - Procurement and financing (for establishing best practices that can bring economies of scale and economies of expertise) - Integration of “companion measures” (such as storage and demand-response options that can benefit customer and utility net load shapes) - Pricing in program design (including best practices for integration of identified value in program prices or credits) The CSVP directly engaged the Sacramento Municipal Utility District (SMUD), the Public Service Company of New Mexico (PNM), and more than a dozen other utilities to develop improved community solar program designs. The outcomes include a plan at SMUD for over 100 MW or more of community and shared solar and support for new or expanded programs at 15 other utilities so far. Resulting best-practice solutions have not only informed program applications, but also have generated discussion among experts and industry associations about the new opportunities and challenges CSVP has brought forth. In these ways, the CSVP has impacted community solar programs and DER plans, competitive innovations and policies nationwide. The CSVP team has been led by Extensible Energy under John Powers, President and CEO. Jill Cliburn, of Santa Fe, NM-based Cliburn and Associates, has served as Principal Investigator. The team also benefitted from expertise from Navigant, Olivine Inc. and Millennium Energy, LLC, in addition to the collaborative and cost

Using a simple formulation of scheduling utility, we show that the maximal expected utility is linear in the mean and standard deviation of trip duration, regardless...... of the form of the standardised distribution of trip durations. This insight provides a unification of the scheduling model and models that include the standard deviation of trip duration directly as an argument in the cost or utility function. The results generalise approximately to the case where the mean...

  12. Steganography based on pixel intensity value decomposition

    Science.gov (United States)

    Abdulla, Alan Anwar; Sellahewa, Harin; Jassim, Sabah A.

    2014-05-01

    This paper focuses on steganography based on pixel intensity value decomposition. A number of existing schemes such as binary, Fibonacci, Prime, Natural, Lucas, and Catalan-Fibonacci (CF) are evaluated in terms of payload capacity and stego quality. A new technique based on a specific representation is proposed to decompose pixel intensity values into 16 (virtual) bit-planes suitable for embedding purposes. The proposed decomposition has a desirable property whereby the sum of all bit-planes does not exceed the maximum pixel intensity value, i.e. 255. Experimental results demonstrate that the proposed technique offers an effective compromise between payload capacity and stego quality of existing embedding techniques based on pixel intensity value decomposition. Its capacity is equal to that of binary and Lucas, while it offers a higher capacity than Fibonacci, Prime, Natural, and CF when the secret bits are embedded in 1st Least Significant Bit (LSB). When the secret bits are embedded in higher bit-planes, i.e., 2nd LSB to 8th Most Significant Bit (MSB), the proposed scheme has more capacity than Natural numbers based embedding. However, from the 6th bit-plane onwards, the proposed scheme offers better stego quality. In general, the proposed decomposition scheme has less effect in terms of quality on pixel value when compared to most existing pixel intensity value decomposition techniques when embedding messages in higher bit-planes.

  13. Evaluating long term forecasts

    The U.S. Department of Energy's Energy Information Administration (EIA), and its predecessor organizations, has published projections of U.S. energy production, consumption, distribution and prices annually for over 30 years. A natural issue to raise in evaluating the projections is an assessment of their accuracy compared to eventual outcomes. A related issue is the determination of the sources of 'error' in the projections that are due to differences between the actual versus realized values of the associated assumptions. One way to do this would be to run the computer-based model from which the projections are derived at the time the projected values are realized, using actual rather than assumed values for model assumptions; and, compare these results to the original projections. For long term forecasts, this approach would require that the model's software and hardware configuration be archived and available for many years, possibly decades, into the future. Such archival creates many practical problems; and, in general, it is not being done. This paper reports on an alternative approach for evaluating the projections. In the alternative approach, the model is run many times for cases in which important assumptions are changed individually and in combinations. A database is assembled from the solutions and a regression analysis is conducted for each important projected variable with the associated assumptions chosen as exogenous variables. When actual data are eventually available, the regression results are then used to estimate the sources of the differences in the projections of the endogenous variables compared to their eventual outcomes. The results presented here are for residential and commercial sector natural gas and electricity consumption. (author)

  14. The value of diversity

    International Nuclear Information System (INIS)

    Jones, P.M.S.

    1994-01-01

    Although the adoption of a range of fuels employing different technologies incurs extra cost, diversity can provide a measure of security against supply disruption, fuel price escalation and environmental regulatory changes. Attempts to set a value to diversity in the United Kingdom are reviewed. Most of these have explored the economic impact of different mixes of fuels and/or technologies against a series of postulated fuel price and energy demand scenarios. They depend on the reliability of the cost and technical performance inputs, and subjective judgements about future price and demand developments; these factors undermine confidence in quantitative outputs of such methods. The novel approach of Stirling is presented. This seeks to derive an optimum plant/fuel mix using generation costs for a wide range of options and a marginal value for incremental changes in diversity, based on a specified diversity index. Stirling's approach could be argued to support the maintenance or expansion of the existing nuclear component of United Kingdom power supplies and an increase in the contribution from renewables. However, problems within the method which is still under development limits the weight that can be attached to its findings at present. Given the closely comparable financial costs, a reasonable balance at this time would seem to consist of the available level of low cost renewables and roughly equal tranches of gas, nuclear and coal. A smaller coal-fired component would be appropriate if environmental costs are taken into account. (19 references). (UK)

    At a time of fake news, hacks, leaks, and unverified reports, many people are unsure whom to believe. How can we communicate in ways that make individuals question their assumptions and learn? My colleagues at The Hastings Center and many journalists and scientists are grappling with this question and have, independently, reached the same first step: recognize that facts can't be fully understood without probing their connection to values. "Explaining the basics is important, of course, but we also need to diversify our approach to the coverage of science-particularly as it intersects with the matrix of cultural, religious, social, and political values of our readers," said an article in Undark, an online magazine of science journalism. An editorial in Nature called for scientists to engage directly with citizens in debates over climate change and genome editing, noting that "the ethical issues can be critically dependent on the science, for example, in understanding where the boundaries between non-heritable and heritable genome modifications might be."

    The calculations which underlie efforts to balance marketing spending on customer acquisition and customer retention are usually based on either single- period customer profitability or forecasts of customer lifetime value (CLTV). This paper argues instead for risk-adjusted CLTV, which is termed the economic value (EV) of a customer, as the means for marketing to assess both customer profitability and shareholder value gains.

  18. The value of place

    Dentzau, Michael W.

    2014-03-01

    This commentary seeks to expand the dialogue on place-based science education presented in Katie Lynn Brkich's article, where the connections fifth grade students make between their formal earth science curriculum and their lived experiences are highlighted. The disconnect between the curriculum the students are offered and their immediate environment is clear, and we are presented with examples of how they strive to make connections between the content and what they are familiar with—namely their surroundings. "Place" is identified as a term with complex meanings and interpretations, even in the scope of place-based science education, and understanding how the term is used in any given scenario is essential to understanding the implications of place-based education. Is place used as a location, locale or a sense of place? To understand "place" is to acknowledge that for the individual, it is highly situational, cultural and personal. It is just such attributes that make place-based education appealing, and potentially powerful, pedagogically on one hand, yet complex for implementation on the other. The argument is posed that place is particularly important in the context of education about the environment, which in its simplest manifestation, connects formal science curriculum to resources that are local and tangible to students. The incorporation of place in such a framework seeks to bridge the gap between formal school science subjects and students' lived experiences, yet acknowledges the tensions that can arise between accommodating place meanings and the desire to acculturate students into the language of the scientific community. The disconnect between guiding policy frameworks and the reality of the Next Generation Science Standards is addressed opening an avenue for further discussion of the importance of socio-cultural frameworks of science learning in an ever increasing era of accountability.

  19. The Contribution of Intellectual Capital to Value Creation

    2013-12-01

    Full Text Available This paper studies the marginal contribution of intellectual capital (IC components to company value using a hedonic pricing framework. The ANOVA is used to identify group differences among different national markets and industries. Two models have been developed to reflect the time effect: one related to the immediate creation of value and another for the long term. As could be expected, the contribution of IC to companies’ value creation differs significantly between countries and industries. Both models, short- and long-term, are significant and with a normal explanatory power. We have found both positive and negative coefficients. Human capital plays a critical positive role in value creation in the short term. Structural and relational capital becomes more relevant in the long term. However, in the long term, the results obtained regarding the effect of human capital are unclear.

    Health care is in a state of transition, shifting from volume-based success to value-based success. Hospital executives and referring physicians often do not understand the total value a radiology group provides. A template for easy, cost-effective implementation in clinical practice for most radiology groups to demonstrate the value they provide to their clients (patients, physicians, health care executives) has not been well described. A value management program was developed to document all of the value-added activities performed by on-site radiologists, quantify them in terms of time spent on each activity (investment), and present the benefits to internal and external stakeholders (outcomes). The radiology value-added matrix is the platform from which value-added activities are categorized and synthesized into a template for defining investments and outcomes. The value management program was first implemented systemwide in 2013. Across all serviced locations, 9,931.75 hours were invested. An annual executive summary report template demonstrating outcomes is given to clients. The mean and median individual value-added hours per radiologist were 134.52 and 113.33, respectively. If this program were extrapolated to the entire field of radiology, approximately 30,000 radiologists, this would have resulted in 10,641,161 uncompensated value-added hours documented in 2013, with an estimated economic value of $2.21 billion.

    In order to unveil the value of network connectivity, we formalize the construction of ecological networks in forest environments as an optimal control dynamic graph-theoretic problem. The network is based on a set of bioreserves and patches linked by ecological corridors. The node dynamics, built upon the consensus protocol, form a time evolutive Mahalanobis distance weighted by the opportunity costs of timber production. We consider a case of complete graph, where the ecological network is fully connected, and a case of incomplete graph, where the ecological network is partially connected. The results show that the network equilibrium depends on the size of the reception zone, while the network connectivity depends on the environmental compatibility between the ecological areas. Through shadow prices, we find that securing connectivity in partially connected networks is more expensive than in fully connected networks, but should be undertaken when the opportunity costs are significant.

    A discussion on how Westcoast Gas Services Inc., is striving to meet customer satisfaction was presented. A strategic business unit called storage, transportation and service is a customer-centered, energy service enterprise dedicated to providing value-added service. The company is placing emphasis on better coordination of sales and marketing activities, especially in areas of customer relationship management and product development. Deregulation was responsible for the changing marketplace. It resulted in increased competition, energy alliances and multi-fuel opportunities. Some of the ways Westcoast Gas Service plans to survive and prosper in this new world of competition were outlined. Among the ideas mentioned were consumer orientation, superior information about consumers and competitors, quick adaptation to changing market conditions, anticipation of consumer needs, and appropriate product development

The author’s intention is to stress the main points of divergence between moralistic-valuable rhetoric and the foreign policy practice of the U.S. In that sense, the examples of the American stand, i.e. the active treatment of the Yugoslav crisis, on the one hand, and the crisis in the Persian Gulf, on the other hand, is considered. The author’s conclusion is that the foreign policy of the only current super-power is still directed by interests rather then by values. In the concluding part, the author presents an anthropologic argument in favor of reestablishing "balance of power" as the only guarantee for peace and stability of the world.

    As electricity markets deregulate and energy tariffs increasingly expose customers to commodity price volatility, it is difficult for energy consumers to assess the economic value of investments in technologies that manage electricity demand in response to changing energy prices. The key uncertainties in evaluating the economics of demand-response technologies are the level and volatility of future wholesale energy prices. In this paper, we demonstrate that financial engineering methodologies originally developed for pricing equity and commodity derivatives (e.g., futures, swaps, options) can be used to estimate the value of demand-response technologies. We adapt models used to value energy options and assets to value three common demand-response strategies: load curtailment, load shifting or displacement, and short-term fuel substitution-specifically, distributed generation. These option models represent an improvement to traditional discounted cash flow methods for assessing the relative merits of demand-side technology investments in restructured electricity markets.

  11. The innovation value chain.

    Hansen, Morten T; Birkinshaw, Julian

    2007-06-01

    The challenges of coming up with fresh ideas and realizing profits from them are different for every company. One firm may excel at finding good ideas but may have weak systems for bringing them to market. Another organization may have a terrific process for funding and rolling out new products and services but a shortage of concepts to develop. In this article, Hansen and Birkinshaw caution executives against using the latest and greatest innovation approaches and tools without understanding the unique deficiencies in their companies' innovation systems. They offer a framework for evaluating innovation performance: the innovation value chain. It comprises the three main phases of innovation (idea generation, conversion, and diffusion) as well as the critical activities performed during those phases (looking for ideas inside your unit; looking for them in other units; looking for them externally; selecting ideas; funding them; and promoting and spreading ideas companywide). Using this framework, managers get an end-to-end view of their innovation efforts. They can pinpoint their weakest links and tailor innovation best practices appropriately to strengthen those links. Companies typically succumb to one of three broad "weakest-link" scenarios. They are idea poor, conversion poor, or diffusion poor. The article looks at the ways smart companies - including Intuit, P&G, Sara Lee, Shell, and Siemens- modify the best innovation practices and apply them to address those organizations' individual needs and flaws. The authors warn that adopting the chain-based view of innovation requires new measures of what can be delivered by each link in the chain. The approach also entails new roles for employees "external scouts" and "internal evangelists," for example. Indeed, in their search for new hires, companies should seek out those candidates who can help address particular weaknesses in the innovation value chain.

    An assessment was made of the Energy Data Base (EDB) of the Department of Energy's Technical Information Center (TIC). As the major resource containing access information to the world's energy literature, EDB products and services are used extensively by energy researchers to identify journal articles, technical reports and other items of potential utility in their work. The approach taken to assessing value begins with the measurement of extent of use of the EDB. Apparent value is measured in terms of willingness to pay. Consequential value is measured in terms of effect - for searching, the cost of reading which results; and for reading, the savings which result from the application of the information obtained in reading. Resulting estimates of value reflect value to the searchers, the reader, and the reader's organization or funding source. A survey of the 60,000 scientists and eingineers funded by the DOE shows that annually they read about 7.1 million journal articles and 6.6 million technical reports. A wide range of savings values were reported for one-fourth of all article readings and three-fourths of all report readings. There was an average savings of $590 per reading of all articles; there was an average savings of $1280 for technical reports. The total annual savings attributable to reading by DOE-funded scientists and engineers is estimated to be about $13 billion. An investment of $5.3 billion in the generation of information and about $500 million in processing and using information yields a partial return of about $13 billion. Overall, this partial return on investment is about 2.2 to 1. In determining the value of EDB only those searches and readings directly attributable to it are included in the analysis. The values are $20 million to the searchers, $117 million to the readers and $3.6 billion to DOE.

    The term "critical values" can be defined to entail laboratory test results that significantly lie outside the normal (reference) range and necessitate immediate reporting to safeguard patient health, as well as those displaying a highly and clinically significant variation compared to previous data. The identification and effective communication of "highly pathological" values has engaged the minds of many clinicians, health care and laboratory professionals for decades, since these activities are vital to good laboratory practice. This is especially true in hemostasis, where a timely and efficient communication of critical values strongly impacts patient management. Due to the heterogeneity of available data, this paper is hence aimed to analyze the state of the art and provide an expert opinion about the parameters, measurement units and alert limits pertaining to critical values in hemostasis, thus providing a basic document for future consultation that assists laboratory professionals and clinicians alike. KEY MESSAGES Critical values are laboratory test results significantly lying outside the normal (reference) range and necessitating immediate reporting to safeguard patient health. A broad heterogeneity exists about critical values in hemostasis worldwide. We provide here an expert opinion about the parameters, measurement units and alert limits pertaining to critical values in hemostasis.

    Full Text Available The management of the enterprise's value is largely aimed at increasing the investment attractiveness of the enterprise. The search for new methods and techniques for managing the property complex faces a number of problems that are a promise of developing scientific approaches to the development of new progressive methods of making managerial decisions. The article considers alternative options for improving the quality of enterprise management and suggests the direction of improving the organization’s cost management system. A number of limiting factors, which allowed the author to determine the target indicators of the presented model, determines the presented objective function of enterprise value. It is permissible to change and expand the composition of the indicators and the approaches used to assess the value of the enterprise. The recommended model allows determining the reserves of increasing the efficiency of the enterprise, affecting the value of the property complex. Dependence of the singled out evaluation criteria and the targets of strategies for increasing the value of enterprises is indicated. The main stages of the enterprise value management process are considered as a single concept of increasing the current value of the organization. The characteristic of the concept of management aimed at creating valueValue Based Management (VBM is presented. The main principles of VBM aimed at qualitative improvement of strategic and operational decisions at all levels of management of the organization are singled out.

    Traditional transportation planning and evaluation practices treat walking as a minor transport mode. However, it is evident that walking is a critical component of the transport system. This paper presents a series of methods to evaluate the value of walking and walkability, which is defined as the quality of walking conditions, including safety, comfort and convenience. The socio-economic benefits of walking and walkability were discussed, including basic mobility, consumer cost savings and reduced external costs. Efficient land use, community livability, improved public health, economic development and support for equity objectives were also presented as potential benefits. It was concluded that walking receives less than its appropriate share of transportation resources, and that improvements in walkability can provide a high economic return on investment. Increased government funding to walking facilities and programs was recommended. Other recommendations included: shifting road space from traffic and parking lanes to sidewalks and paths; and policies to create more walkable safety and comfort. These recommendations comply with other transport and land use management reforms to reduce automobile dependency and create greater accessibility. refs., tabs., figs.

    Full Text Available Over the last two decades, inclusion and participation have become leading policy concepts within the Dutch chronic care and social welfare sector. People with an intellectual or psychiatric disability ought to get a chance to participate in, and belong to, the mainstream of our society—on the basis of equality and equivalence. Although on an international level this pursuit has been going on for at least five decades, it still raises all kinds of questions and debates. What does it mean if we want people with intellectual and/or psychiatric disabilities to participate in our society? Based on which idea(ls about humanity do we define equality and equivalence? And by doing so, how much space is left for individual differences? In the following dialogue the two authors navigate the tension between similarity and difference in thinking about—and working towards—more space for marginalized people. In an attempt to withstand the contemporary dominance of equality thinking, marked by a strong focus on tenability and autonomy—and by extension an increasing climate of taboo around vulnerability and dependency—both authors stress the importance of recognizing and valuing difference, while discussing encounters between people with and without a severe intellectual and/or multiple disability.

  2. Digital Information and Value

    2015-11-01

    Full Text Available Digital information changes the ways in which people and organisations interact. This paper examines the nature of this change in the context of the author’s Model for Information (MfI. It investigates the relationship between outcomes and value, selection processes and some attributes of information and explores how this relationship changes in the move from analogue to digital information. Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change. The relationships established in the paper enable an analysis of, and guide changes to, these conventions enabling a more effective use of digital information.

    Full Text Available At present, in terms of intercultural communication, the role of the axiological aspect in teaching foreign languages is growing. When thinking about the values and anti-values in the phraseology of Russian and German it is advisable to take into account their hierarchy which can be presented as the axiological scale. This investigation benefits from the following methods: axiological linguistic method, method of cognitive analysis, comparative method, processing of lexicographical sources. The result of the study is formation of the axiological scale and development on its basis of the taxonomic model of values and anti-values in the phraseology of the Russian and German languages. The taxonomic model of values and anti-values in the phraseology of the language allows submitting axiological hierarchy reflecting the inter-layer differentiation of values and anti-values represented by axiological phraseology. Axiological scale and taxonomic model of values and anti-values in the Russian and German phraseology can be used in linguistic axiological research of different languages.

    Full Text Available It is too easy to make light of ‘new literacies’ by saying things like: “Well, there are always newer ones coming along”. Such remarks suggest new literacies have a similar kind of life trajectory to an automobile: new in 2009, semi-new in 2010, and old hat by 2011. Against this kind of “that’s so yesterday” perspective, we suggest in this article that ‘new literacies’ are best understood in terms of an historical period of social, cultural, institutional, economic, and intellectual change that is likely to span many decades – some of which are already behind us. We associate new literacies with an historical conjuncture and an ascending social paradigm. From this perspective we suggest that the kinds of practices we currently identify as new literacies will cease to be ‘new’ once the social ways characterizing the ascending paradigm have become sufficiently establised and grounded to be regarded as conventional. Furthermore we suggest that at the heart of the idea of new ethos stuff is the idea of technological change aligning with a range of increasingly popular values.

    Full Text Available When Su Cleyle and I first decided to start Evidence Based Library and Information Practice, one of the things we agreed upon immediately was that the journal be open access. We knew that a major obstacle to librarians using the research literature was that they did not have access to the research literature. Although Su and I are both academic librarians who can access a wide variety of library and information literature from our institutions, we belong to a profession where not everyone has equal access to the research in our field. Without such access to our own body of literature, how can we ever hope for practitioners to use research evidence in their decision making? It would have been contradictory to the principles of evidence based library and information practice to do otherwise.One of the specific groups we thought could use such an open access venue for discovering research literature was school librarians. School librarians are often isolated and lacking access to the research literature that may help them prove to stakeholders the importance of their libraries and their role within schools. Certainly, school libraries have been in decline and the use of evidence to show value is needed. As Ken Haycock noted in his 2003 report, The Crisis in Canada’s School Libraries: The Case for Reform and Reinvestment, “Across the country, teacher-librarians are losing their jobs or being reassigned. Collections are becoming depleted owing to budget cuts. Some principals believe that in the age of the Internet and the classroom workstation, the school library is an artifact” (9. Within this context, school librarians are looking to our research literature for evidence of the impact that school library programs have on learning outcomes and student success. They are integrating that evidence into their practice, and reflecting upon what can be improved locally. They are focusing on students and showing the impact of school libraries and

    Full Text Available Two value concepts are dominant in the social sciences: (1 Schwartz's theory of basic human values, measured through the Portrait Values Questionnaire (ESS and (2 Inglehart's postmaterialism and Welzel's extension to the self-expression values scale (WVS/EVS. To advance research in values, two questions need to be addressed: (1 Are the concepts and measurements of values in the different approaches interchangeable? (2 Which of the concepts performs better for explaining moral and social attitudes? This study contributes to the discussion on value concepts by comparing these value instruments using individual level data from an online access panel (n = 762 and assessing the performance of values instruments for microexplanations of moral (end-of-life attitudes and sexual morality and social attitudes (xenophobia. Overall, the measurement model of basic human values with the PVQ provides a sound basis for comparing the Schwartz values to postmaterialism and self-expression values. In both cases, there are positive correlations with universalism and self-direction and negative correlations with tradition/conformity and security, which do not exceed 0.4. Regarding the performance, it turns out that the Schwartz values are in toto a more powerful tool than both Inglehart's postmaterialism and Welzel's self-expression values, in terms of explained variance as well as in terms of standardized effects.

The purpose of this study was to analyze the Cc cases in our material with respect to all prognostic values including histological type and grade, vascular invasion, perineural invasion, and tumor border features. There were investigated 149 cases of resection specimen with colorectal cancer, which were fixed in buffered neutral formalin and embedded in paraffin. Tissue sections (4(µm thick were cut and stained with H&E. Adenocarcinoma was the most frequent histological type found in 85,90% of cases, in 60,94% of males and 39,06% of females; squamous cell carcinoma in 7,38%, in 63,63% of males and 36,36% of females; mucinous carcinoma in 4,68%, in 57,15% of males and 42,85% of females; while adenosquamous carcinoma, undifferentiated carcinoma and carcinoma in situ in 0,71% of cases each. Dukes' classification was used in order to define the depth of invasion. Dukes B was found in 68,45% of cases, whereas in 31,54% of cases Dukes C was found. As far as histological grading is concerned, Cc was mostly with moderate differentiation (75,16% with neither vascular nor perineural invasion. Resection margins were in all cases free of tumor. Our data indicate that the pathologic features of the resection specimen constitute the most powerful predictors of postoperative outcome in Cc. Dukes' stage and degree of differentiation provide independent prognostic information in Cc. However, differentiation should be assessed by the worst pattern.

  14. Adaptive value of sex in microbial pathogens.

    2008-05-01

    Explaining the adaptive value of sex is one of the great outstanding problems in biology. The challenge comes from the difficulty in identifying the benefits provided by sex, which must outweigh the substantial costs of sex. Here, we consider the adaptive value of sex in viruses, bacteria and fungi, and particularly the information available on the adaptive role of sex in pathogenic microorganisms. Our general theme is that the varied aspects of sex in pathogens illustrate the varied issues surrounding the evolution of sex generally. These include, the benefits of sex (in the short- and long-term), as well as the costs of sex (both to the host and to the pathogen). For the benefits of sex (that is, its adaptive value), we consider three hypotheses: (i) sex provides for effective and efficient recombinational repair of DNA damages, (ii) sex provides DNA for food, and (iii) sex produces variation and reduces genetic associations among alleles under selection. Although the evolution of sex in microbial pathogens illustrates these general issues, our paper is not a general review of theories for the evolution of sex in all organisms. Rather, we focus on the adaptive value of sex in microbial pathogens and conclude that in terms of short-term benefits, the DNA repair hypothesis has the most support and is the most generally applicable hypothesis in this group. In particular, recombinational repair of DNA damages may substantially benefit pathogens when challenged by the oxidative defenses of the host. However, in the long-term, sex may help get rid of mutations, increase the rate of adaptation of the population, and, in pathogens, may infrequently create new infective strains. An additional general issue about sex illustrated by pathogens is that some of the most interesting consequences of sex are not necessarily the reasons for which sex evolved. For example, antibiotic resistance may be transferred by bacterial sex, but this transfer is probably not the reason sex

    The purpose of this study was to measure professional and personal values among nurses, and to identify the factors affecting these values. The participants were 323 Israeli nurses, who were asked about 36 personal values and 20 professional values. The three fundamental professional nursing values of human dignity, equality among patients, and prevention of suffering, were rated first. The top 10 rated values all concerned nurses' responsibility towards patients. Altruism and confidentiality were not highly rated, and health promotion and nursing research were rated among the last three professional values. For personal (instrumental) values, honesty, responsibility and intelligence were rated first, while ambition and imagination were rated 14th and 16th respectively out of 18. Significant differences (P personal and professional values rated as functions of culture, education, professional seniority, position and field of expertise. The results may assist in understanding the motives of nurses with different characteristics and help to promote their work according to professional ethical values.

  19. Do We Really Value Learning?

    Science.gov (United States)

    Moore, John W.

    1999-01-01

    University faculty think of their institutions as places in which learning is valued and pride themselves on the discovery of new knowledge. Indeed universities have been unusually successful in supporting research and developing new knowledge that has been enormously beneficial to society, and university faculty value learning far more than the average. But some kinds of learning are more valued than others-a fact that I believe is detrimental to the long-term welfare of both universities and society. By far the most valued learning is by someone who discovers what nobody else has learned before. We call the process of achieving such learning "research". It is the coin of the academic realm, at least partly because it is easy to evaluate. Those who do it creatively can reap the rewards of respect from their colleagues, better facilities and instrumentation from their institutions, regional and national awards from their disciplinary societies, and increased funding from government and industry for their endeavors. Significantly less valued are activities that help others to learn, especially when the learning involves things already known by many. We call such activities "teaching", although the dictionary definition of "teach" ("to show how to do something; give instructions to; train") is not broad enough to encompass the range of activities currently being used to encourage learning. There is a widespread notion that teaching is easy and requires no real creativity. Nontenured faculty are often warned that time spent on teaching will be thought of as "wasted", and those well established in research have been criticized for spending too much of their time on the "unproductive" activity of teaching. Teaching is held out to students as a fall-back position in case their other career plans do not pan out, and sometimes those who educate teachers are willing to accept less than the highest quality from the students to whom they provide credentials. Those who employ

    Full Text Available The climate regime addresses one of the most important challenges facing humankind today. However, while the environmental and economic sides of the problem are well represented, it lacks the inclusion of social and human aspects. The human rights regime, in contrast, is a regime which has been established precisely to implement human values. This article ex-plains the problems of climate change in terms of human values and argues that some proce-dures from the human rights regime offer possibilities for improvement. It is submitted that through the inclusion of human rights instruments, such as individual communication, pro-gressive realisation and authoritative interpretation, the inclusion of human values into the climate regime will be facilitated. This article presents these instruments and discusses their potential for inclusion in the climate regime.

    Full Text Available This paper attempts to integrate Value Stream Map (VSM with the cost aspects. A value stream map provides a blueprint for implementing lean manufacturing concepts by illustrating information and materials flow in a value stream. The objective of the present work is to integrate the various cost aspects. The idea is to introduce a cost line, which enhances the clarity in decision making. The redesigned map proves to be effective in highlighting the improvement areas, in terms of quantitative data. TAKT time calculation is carried out to set the pace of production. Target cost is set as a bench mark for product cost. The results of the study indicates that implementing VSM led to reduction in the following areas: processing lead time by 34%, processing cycle time was reduced by 35%, Inventory level by 66% and product cost from Rs 137 to Rs 125. It was found that adopting VSM in a small scale industry can make significant improvements.

    2014-11-01

    Full Text Available Values affect humans’ perception of situations and problems and guide our actions. The objective of this study was to explore the values of dairy farmers, and whether their values influenced their decisions to maintain dairy farming or to buy consultancy services. During late fall 2007 we visited and interviewed 90 farmers. First we did a qualitative analysis of the data and then we merged the interview data with the existing database of financial data from the year 2007 to do statistical analyses. We also checked whether the farmers still produced milk in 2013, six years after the interviews.  Most farmers had terminal values like keeping up the tradition and to have an interesting work. Value combinations with instrumental values such as to earn money and to produce milk were common. Realizing that many farmers prioritize terminal values over instrumental values has important consequences for dairy companies, dairy consultants and politicians.

    Snow is the natural resource, like soil and water. It has specific properties which allow its use not just for skiing but also for houses cooling in summer (Swedish experience), for air fields construction (Arctic and Antarctic), for dams (north of Russia), for buildings (not only snow-houses of some Polar peoples but artistic hotel attracting tourists in Sweden), and as art material (Sapporo snow festival, Finnish events), etc. "Adjustment" of snow distribution and amount is not only rather common practice (avalanche-protection constructions keeping snow on slopes) but also the practice with long history. So-called "snow irrigation" was used in Russia since XIX century to protect winter crop. What is now named "artificial snow production", is part of much larger pattern. What makes it special—it is unavoidable in present climate and economy situation. 5% of national income in Austria is winter tourism. 50% of the economy in Savoy relay on winter tourism. In terms of money this can be less, but in terms of jobs and income involved this would be even more considerable in Switzerland. As an example—the population of Davos is 14000 in Summer and 50000 in Winter. Skiing is growing business. In present time you can find ski slopes in Turkey and Lebanon. To keep a cite suitable for attracting tourists you need certain amount of sunny days and certain amount of snow. The snow cannons are often the only way to keep a place running. On the other hand, more artificial snow does not necessary attract more tourists, while heavy natural snowfall does attract them. Artificial snow making is costly and requires infrastructure (ponds and electric lines) with very narrow range of weather conditions. Related companies are searching for alternatives and one of them can be "weather regulation" by distribution of some chemical components in clouds. It did not happen yet, but can happen soon. The consequences of such interference in Nature is hardly known. The ski tourism is not the

  12. Leadership values in academic medicine.

    To gain a deeper understanding of the guiding core values that deans of academic medical centers (AMCs) considered most essential for their leadership and the major leadership challenges that confront them. In 2003-04, semistructured interviews of 18 deans at U.S. colleges of medicine or AMCs were organized around four dimensions: background, leadership challenges, organizational effectiveness, and systems enablers/restrainers for leadership. A values Q-sort was used to determine how widely core values were shared among deans and how the complex challenges they faced did or did not align with these values. Fourteen of the 18 (78%) deans identified financial difficulties as their most pressing leadership challenge, followed by weak institutional alignment (61%), staffing problems (33%), and poor morale (28%). Open, candid communication was reported as the most effective means of addressing these complex problems. Enacting espoused shared values and having a positive attitude were identified as the most important enablers of systemic leadership, whereas micromanagement and difficult people were the major restraints. Q-sort results on 38 positive leadership values indicated that participants considered integrity most essential. Integrity was positively correlated with humanistic values and negatively correlated with results. Vision, another highly espoused value, correlated strongly with performance-oriented values but correlated negatively with humanistic values. A dynamic tension exists in AMCs between humanistic values and performance-based core values. The ability to manage that tension (i.e., when to prioritize one set of values over the other) is inherent in a dean's work.

  13. Age and personal values: Similar value circles with shifting priorities.

    This study examined the relationship of personal values to age using data from two representative surveys. We hypothesized that individuals organize personal values, regardless of their age, as a circle with the same order of values on this circle but that older persons are closer to conservation and more remote from openness to change and closer to self-transcendence and more distant from self-enhancement. The structural stability of the value circle over age was largely confirmed across and within individuals. Different age groups exhibited a tendency to more strongly cluster those values that they rated as relatively important. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    There is a growing interest in values-led inquiries within participatory design. One approach argues that working with values is a recursive 3-phase process that supports the emergence, development and grounding of values. In this paper we focus solely upon the emergence phase, proposing...... an approach that can support the emergence of values during the initial phase of a values-led inquiry. To illustrate this approach and to ground our discussion, we draw from a recent participatory design case where we were engaged in the design of digital technology to support the experiences of young adults...... with severe intellectual disabilities, in an art museum. By describing how we establish, negotiate and the debrief values during this initial phase of a values-led inquiry.

  17. Neurocognitive Mechanisms Underlying Value-Based Decision-Making: From Core Values to Economic Value

    2013-07-01

    Full Text Available Value plays a central role in practically every aspect of human life that requires a decision: whether we choose between different consumer goods, whether we decide which person we marry or which political candidate gets our vote, we choose the option that has more value to us. Over the last decade, neuroeconomic research has mapped the neural substrates of economic value, revealing that activation in brain regions such as ventromedial prefrontal cortex (VMPFC, ventral striatum or posterior cingulate cortex reflects how much an individual values an option and which of several options he/she will choose. However, while great progress has been made exploring the mechanisms underlying concrete decisions, neuroeconomic research has been less concerned with the questions of why people value what they value, and why different people value different things. Social psychologists and sociologists have long been interested in core values, motivational constructs that are intrinsically linked to the self-schema and are used to guide actions and decisions across different situations and different time points. Core value may thus be an important determinant of individual differences in economic value computation and decision-making. Based on a review of recent neuroimaging studies investigating the neural representation of core values and their interactions with neural systems representing economic value, we outline a common framework that integrates the core value concept and neuroeconomic research on value-based decision-making.

  2. Introduction: Long term prediction

    International Nuclear Information System (INIS)

    Beranger, G.

    2003-01-01

    Making a decision upon the right choice of a material appropriate to a given application should be based on taking into account several parameters as follows: cost, standards, regulations, safety, recycling, chemical properties, supplying, transformation, forming, assembly, mechanical and physical properties as well as the behaviour in practical conditions. Data taken from a private communication (J.H.Davidson) are reproduced presenting the life time range of materials from a couple of minutes to half a million hours corresponding to applications from missile technology up to high-temperature nuclear reactors or steam turbines. In the case of deep storage of nuclear waste the time required is completely different from these values since we have to ensure the integrity of the storage system for several thousand years. The vitrified nuclear wastes should be stored in metallic canisters made of iron and carbon steels, stainless steels, copper and copper alloys, nickel alloys or titanium alloys. Some of these materials are passivating metals, i.e. they develop a thin protective film, 2 or 3 nm thick - the so-called passive films. These films prevent general corrosion of the metal in a large range of chemical condition of the environment. In some specific condition, localized corrosion such as the phenomenon of pitting, occurs. Consequently, it is absolutely necessary to determine these chemical condition and their stability in time to understand the behavior of a given material. In other words the corrosion system is constituted by the complex material/surface/medium. For high level nuclear wastes the main features for resolving problem are concerned with: geological disposal; deep storage in clay; waste metallic canister; backfill mixture (clay-gypsum) or concrete; long term behavior; data needed for modelling and for predicting; choice of appropriate solution among several metallic candidates. The analysis of the complex material/surface/medium is of great importance

  19. Make your values mean something.

    Science.gov (United States)

    Lencioni, Patrick M

    2002-07-01

    Take a look at this list of corporate values: Communication. Respect. Integrity. Excellence. They sound pretty good, don't they? Maybe they even resemble your own company's values. If so, you should be nervous. These are the corporate values of Enron, as claimed in its 2000 annual report. And they're absolutely meaningless. Indeed, most values statements, says the author, are bland, toothless, or just plain dishonest. And far from being harmless, as some executives assume, they're often highly destructive. Empty values statements create cynical and dispirited employees and undermine managerial credibility. But coming up with strong values--and sticking to them--isn't easy. Organizations that want their values statements to really mean something should follow four imperatives. First, understand the different types of values: core, aspirational, permission-to-play, and accidental. Confusing them with one another can bewilder employees and make management seem out of touch. Second, be aggressively authentic. Too many companies view a values initiative in the same way they view a marketing launch: a onetime event measured by the initial attention it receives, not by its content. Third, own the process. Values initiatives are about imposing a set of fundamental, strategically sound beliefs on a broad group of people. That's why the best values efforts are driven by small teams. Finally, weave core values into everything. It's not enough to hang your values statement on the wall; it must be integrated into every employee-related process--hiring methods, performance management systems, even dismissal policies. Living by stated corporate values is difficult. But the benefits of doing so can be profound; so can the damage from adopting a hollow set of corporate values.

  20. Value-Based Medicine and Pharmacoeconomics.

    Science.gov (United States)

    Brown, Gary C; Brown, Melissa M

    2016-01-01

    Pharmacoeconomics is assuming increasing importance in the pharmaceutical field since it is entering the public policy arena in many countries. Among the variants of pharmacoeconomic analysis are cost-minimization, cost-benefit, cost-effectiveness and cost-utility analyses. The latter is the most versatile and sophisticated in that it integrates the patient benefit (patient value) conferred by a drug in terms of improvement in length and/or quality of life. It also incorporates the costs expended for that benefit, as well as the dollars returned to patients and society from the use of a drug (financial value). Unfortunately, one cost-utility analysis in the literature is generally not comparable to another because of the lack of standardized formats and standardized input variables (costs, cost perspective, quality-of-life measurement instruments, quality-of-life respondents, discounting and so forth). Thus, millions of variants can be used. Value-based medicine® (VBM) cost-utility analysis standardizes these variants so that one VBM analysis is comparable to another. This system provides a highly rational methodology that allows providers and patients to quantify and compare the patient value and financial value gains associated with the use of pharmaceutical agents for example. © 2016 S.

    Health values are important components of medical decisions. Experimental data suggest that people value health in complex and dynamic ways. Prospect theory is a descriptive theory of choice that may accurately characterize how people assign values to health states. The authors first provide background on prospect theory and how it can be applied to health values. Next, they review the relevant health research and find mixed support for prospect theory. Last, they discuss implications of prospect theory for cost-effectiveness analysis. The application of prospect theory to health deserves further research because it may help clarify the link between health and values.

    Value sensitivity - the ability to recognize value-related issues when they arise in practice - is an indispensable competence for medical practitioners to enter decision-making processes related to ethical questions. However, the psychological competence of value sensitivity is seldom an explicit subject in the training of medical professionals. In this contribution, we outline the traditional concept of moral sensitivity in medicine and its revised form conceptualized as value sensitivity and we propose an instrument that measures value sensitivity. We developed an instrument for assessing the sensitivity for three value groups (moral-related values, values related to the principles of biomedical ethics, strategy-related values) in a four step procedure: 1) value identification (n = 317); 2) value representation (n = 317); 3) vignette construction and quality evaluation (n = 37); and 4) instrument validation by comparing nursing professionals with hospital managers (n = 48). We find that nursing professionals recognize and ascribe importance to principle-related issues more than professionals from hospital management. The latter are more likely to recognize and ascribe importance to strategy-related issues. These hypothesis-driven results demonstrate the discriminatory power of our newly developed instrument, which makes it useful not only for health care professionals in practice but for students and people working in the clinical context as well.

    In light of the recent exodus of foreign insurers from Taiwan and the local insurers’ outcries against the International Financial Reporting Standard (IFRS) 4 Insurance Contracts, we examine the value relevance of financial statements for life insurance firms, with particular interests to the embedded value (EV) disclosure. We find that the EV of equity has an incremental information role for book value of equity, which indicates that the accounting mismatching problem in the insurance indust...

    The value evaluation and accounting of crop germplasm not only provides the theory and method for the price of germplasm, thus makes further lawful and fair transactions, but also ensures the benefits of crop germplasm owners and is also instructive in keeping the foodstuff safety. This paper founded a multidimensional value accounting system, which included physical accounting, value accounting and quality index accounting; individual accounting and total accounting; quantity accounting and quality accounting.

  14. The Value of RFID Benefits vs Costs

    CERN Document Server

    2013-01-01

    RFID technology presents a great potential for creating competitive advantage. By automating and simplifying data collection, it lets users more accurately track assets and monitor key indicators, which in turn gives greater visibility to the operations. However, the benefits received from this technology will be determined by how well it is integrated with the business processes and overall information flow. Because of the fact that the decision to deploy RFID technology in an enterprise is a business decision instead of a technology decision, cost-benefit analysis is a key component of this decision. If an RFID deployment cannot be justified in terms of its economic value to the company, it is not likely to help the company; and consequently, it is not likely to remain a viable deployment over the long term.   The Value of RFID describes the business value of RFID and explains the costs and benefits of this technology comprehensively. Different investment evaluation models are proposed to use in various ap...

    Caregivers' commitment to personal values is linked to caregivers' well-being, although the effects of personal values on caregivers' guilt have not been explored to date. The goal of this study is to analyze the relationship between caregivers´ commitment to personal values and guilt feelings. Participants were 179 dementia family caregivers. Face-to-face interviews were carried out to describe sociodemographic variables and assess stressors, caregivers' commitment to personal values and guilt feelings. Commitment to values was conceptualized as two factors (commitment to own values and commitment to family values) and 12 specific individual values (e.g. education, family or caregiving role). Hierarchical regressions were performed controlling for sociodemographic variables and stressors, and introducing the two commitment factors (in a first regression) or the commitment to individual/specific values (in a second regression) as predictors of guilt. In terms of the commitment to values factors, the analyzed regression model explained 21% of the variance of guilt feelings. Only the factor commitment to family values contributed significantly to the model, explaining 7% of variance. With regard to the regression analyzing the contribution of specific values to caregivers' guilt, commitment to the caregiving role and with leisure contributed negatively and significantly to the explanation of caregivers' guilt. Commitment to work contributed positively to guilt feelings. The full model explained 30% of guilt feelings variance. The specific values explained 16% of the variance. Our findings suggest that commitment to personal values is a relevant variable to understand guilt feelings in caregivers.

  17. The value prescription: relative value theorem as a call to action.

    2012-01-01

    The Joint Commission of Pharmacy Practitioners Future Vision of Pharmacy Practice 2015 (2005) and Project Destiny (2008) clearly defined a vision for transforming community practice pharmacy from a culture of dispensing drugs to the provision of services. Several viable service offerings were identified. Pharmacy has not yet fully capitalized on these opportunities. Pharmacy must demonstrate value in providing these services to remain viable in the marketplace. Many pharmacists do not understand how value is created and lack sufficient marketing skills to position their practice for long-term success. The relative value theorem (RVT) describes in simple terms the key elements that drive purchase decisions and thus marketing decisions: (P+S)×PV=RV (P, price; S, service; PV, perceived value; RV, relative value). A consumer compares the P, extra S, and PV of the purchase against all potential uses of their scarce resources before deciding what to buy. Evidence suggests that understanding and applying the principles of RVT is a critical skill for pharmacy professionals in all practice settings to master if they plan to remain viable players in the health care marketplace of the future.

    For many years electric utilities found it easy to provide value to their shareholders. With a monopoly service and decreasing costs it was easy to sell 70% more electricity each year and earn attractive returns. In the last 20 years electric utilities have teamed that it is not possible to provide value to their shareholders without providing value to their customers. Detroit Edison is learning that customer value is not always what the utility thinks it is. There is no better way to find out what customers value than to ask them. Detroit Edison has done a lot of direct asking in the last couple of years, through market research and individual interviews, and has learned indirectly from customers when a particular program does not succeed as we thought it should. Two areas where more has been learned about customer value are Demand Side Management (DSM) and Power Quality

  1. What Is the Value of Value-Based Purchasing?

    Science.gov (United States)

    Tanenbaum, Sandra J

    2016-10-01

    Value-based purchasing (VBP) is a widely favored strategy for improving the US health care system. The meaning of value that predominates in VBP schemes is (1) conformance to selected process and/or outcome metrics, and sometimes (2) such conformance at the lowest possible cost. In other words, VBP schemes choose some number of "quality indicators" and financially incent providers to meet them (and not others). Process measures are usually based on clinical science that cannot determine the effects of a process on individual patients or patients with comorbidities, and do not necessarily measure effects that patients value; additionally, there is no provision for different patients valuing different things. Proximate outcome measures may or may not predict distal ones, and the more distal the outcome, the less reliably it can be attributed to health care. Outcome measures may be quite rudimentary, such as mortality rates, or highly contestable: survival or function after prostate surgery? When cost is an element of value-based purchasing, it is the cost to the value-based payer and not to other payers or patients' families. The greatest value of value-based purchasing may not be to patients or even payers, but to policy makers seeking a morally justifiable alternative to politically contested regulatory policies.

  10. The Value Of Enhanced Neo Surveys

    Science.gov (United States)

    Harris, Alan W.

    2012-10-01

    NEO surveys have now achieved, more or less, the “Spaceguard Goal” of cataloging 90% of NEAs larger than 1 km in diameter, and thereby have reduced the short-term hazard from cosmic impacts by about an order of magnitude, from an actuarial estimate of 1,000 deaths per year (actually about a billion every million years, with very little in between), to about 100 deaths per year, with a shift toward smaller but more frequent events accounting for the remaining risk. It is fair to ask, then, what is the value of a next-generation accelerated survey to “retire” much of the remaining risk. The curve of completion of survey versus size of NEA is remarkably similar for any survey, ground or space based, visible light or thermal IR, so it is possible to integrate risk over all sizes, with a time variable curve of completion to evaluate the actuarial value of speeding up survey completion. I will present my latest estimate of NEA population and completion of surveys. From those I will estimate the “value” of accelerated surveys such as Pan-STARRS, LSST, or space-based surveys, versus continuing with current surveys. My tentative conclusion is that we may have already reached the point in terms of cost-benefit where accelerated surveys are not cost-effective in terms of reducing impact risk. If not yet, we soon will. On the other hand, the surveys, which find and catalog main-belt and other classes of small bodies as well as NEOs, have provided a gold mine of good science. The scientific value of continued or accelerated surveys needs to be emphasized as the impact risk is increasingly “retired.”

  11. Achieving Value in Primary Care: The Primary Care Value Model.

    2016-03-01

    The patient-centered medical home (PCMH) model provides a compelling vision for primary care transformation, but studies of its impact have used insufficiently patient-centered metrics with inconsistent results. We propose a framework for defining patient-centered value and a new model for value-based primary care transformation: the primary care value model (PCVM). We advocate for use of patient-centered value when measuring the impact of primary care transformation, recognition, and performance-based payment; for financial support and research and development to better define primary care value-creating activities and their implementation; and for use of the model to support primary care organizations in transformation. © 2016 Annals of Family Medicine, Inc.

  12. Value for Whom, by Whom’: Investigating Value Constructs in Non-Profit Project Portfolios

    Directory of Open Access Journals (Sweden)

    Karyne Cheng Siew Ang

    2016-11-01

    Full Text Available In most non-profit organisations (NPOs, there are multiple programs, projects or initiatives running simultaneously. The management of multiple projects in organisations can be coined as project portfolio management (PPM (Archer & Ghasemzadeh 1999; Pennypacker & Dye 2002.  In any project-based organisation, it is critical that selected projects align with and deliver the organisation’s strategy or mission. Decisions about project funding are strategic decisions, particularly when there are resource limitations. In PPM decision making, the allocation of resources to projects requires a clear judgement of value across multiple perspectives. Value has often been expressed in financial terms, however increasingly research indicates that non-financial considerations are equally important in evaluating value. A key task in project portfolio management is to maximise value across the portfolio.  However, value can be a subjective notion, as each person may have different expectations of what is valuable. The involvement of diverse stakeholder interests could create complexities in decision making in non-profit organisations due to value being interpreted in different ways by the stakeholders. Furthermore in order to achieve its purpose, non-profits depend heavily on donors, patrons and sponsors - stakeholders who contribute to the portfolio but are often not the direct recipients of the services provided by the non-profit organisation (Kaplan 2012. Non-profit portfolios often compete with other initiatives for resources and attention from the same donors and sponsors, and may need to constantly justify the value they provide to these stakeholders. Most research about value in PPM has been conducted in the ‘for-profit’ sector. Recent value-based studies in the project portfolio field stress the importance of considering both commercial and non-commercial value in portfolio decision making (Killen, du Plessis & Young 2012; Kopman 2013; Martinsuo

  15. Effluent monitoring: Its purpose and value

    International Nuclear Information System (INIS)

    Schoen, A.A.

    1978-01-01

    The purpose of effluent monitoring is described in terms of the primary objectives, the most important of which is to verify that the facility is functioning as it was designed and that the waste treatment and effluent control systems are performing as planned and expected. The object of a monitoring programme should be periodically re-examined to ensure that the programme serves a contemporary purpose. The value of the effluent monitoring programme is determined by the extent to which users of the monitoring data, i.e. the operator, the regulating authorities and the public, accept the result as indicating that the plant is operating safely, and in an environmentally acceptable manner. The credibility of the monitoring results is therefore the most important factor determining the value of an effluent monitoring programme. (author)

  19. EU, Eastern Europe and Values Imperialism

    Directory of Open Access Journals (Sweden)

    Stephen White

    2014-01-01

    Full Text Available This paper proposes an idea of'values imperialism'as a helpful way of conceptualising the relationship between the EU and the states that came within its sphere of influence after the end of the Cold War, particularly its 'neighbours' in Eastern Europe. Values imperialism places its emphasis on the 'superstructure', including norms, laws and social practices. EU larger objective was that the assumptions about government and ownership that were favoured by the dominant powers (EU and the West in the broad term should be absorbed and recapitulated by those countries that were subordinate. The broad framework ofsubordination was established by the Partnership and Cooperation Agreements that began to be concluded from 1994 onwards. Patterns of'values imperialism'could also be discovered in the EU Common Strategies on Russia and Ukraine that were adopted in 1999. Article also points out several cases when the EU intervened directly in the domestic affairs of the Eastern Europe countries in a manner that was not always compatible with the provisions on state sovereignty: a 'European Instrument for Democracy and Human Rights', launched in 2006, interventions ofEU representatives in the work of local courts and organisation of exit polls, which could be used to discredit the official election results and in this way to undermine the position of local governments. Finally, the author concludes that the EU used 'values imperialism'practices in order to extend its influence, particularly in the Eastern Europe.

  20. Metro nature, environmental health, and economic value.

    Science.gov (United States)

    Wolf, Kathleen L; Robbins, Alicia S T

    2015-05-01

    Nearly 40 years of research provides an extensive body of evidence about human health, well-being, and improved function benefits associated with experiences of nearby nature in cities. We demonstrate the numerous opportunities for future research efforts that link metro nature, human health and well-being outcomes, and economic values. We reviewed the literature on urban nature-based health and well-being benefits. In this review, we provide a classification schematic and propose potential economic values associated with metro nature services. Economic valuation of benefits derived from urban green systems has largely been undertaken in the fields of environmental and natural resource economics, but studies have not typically addressed health outcomes. Urban trees, parks, gardens, open spaces, and other nearby nature elements-collectively termed metro nature-generate many positive externalities that have been largely overlooked in urban economics and policy. Here, we present a range of health benefits, including benefit context and beneficiaries. Although the understanding of these benefits is not yet consistently expressed, and although it is likely that attempts to link urban ecosystem services and economic values will not include all expressions of cultural or social value, the development of new interdisciplinary approaches that integrate environmental health and economic disciplines are greatly needed. Metro nature provides diverse and substantial benefits to human populations in cities. In this review, we begin to address the need for development of valuation methodologies and new approaches to understanding the potential economic outcomes of these benefits.
