  1. The values of life.

    PubMed

    In Life's Dominion Dworkin aims at defusing the controversy about abortion and euthanasia by redefining its terms. Basically it is not a dispute about the right to life, but about its value. Liberals should grant that human life has not only a personal, but also an intrinsic value; conservatives should accept the principle of toleration which requires to let people decide for themselves about matters of intrinsic value. Dworkin fails, however, to distinguish between two kinds of personal value: (1) the value of something to a person, when he actually or dispositionally desires it, or finds it pleasant; and (2) the value of something to a person, when it's objectively contributes to his well-being, as defined by reference to his personal point of view, whether or not he ever perceives it as so contributing. He also fails to distinguish between two meanings of the concept of 'intrinsic value': (3) ultimate, i.e. non-instrumental personal value of kind (2); (4) the impersonal value of something which is not good-for-anybody, but simply good, i.e. not a constituent of someone's well-being. Dworkin argues that the human fetus from conception onwards has a value, that it is not a personal value of kind (1), and therefore must be an intrinsic value. But the value of the life of the fetus is not a personal value of kind (2) either and therefore not an intrinsic value of kind (3): it is normally a constituent of the well-being of the pregnant woman, but that doesn't constitute its value, and it is not good 'for' the fetus itself in the relevant sense, because it doesn't have a personal point of view. If, however, the fetus' life is allowed to have an intrinsic value of kind (4), the conservative cannot be refuted by appeal to the principle of toleration, for this only concerns intrinsic value of kind (3). The liberal, indeed, should recognize that the fetus' life has a value, but it is neither a personal value (1) or (2), nor an impersonal value (4), but rather a relational value which gradually develops from some point substantially later than conception.

  2. Life devoid of value?

    PubMed

    Rapp, M S

    1977-03-19

    6 arguments arise in response to Dr. Baunemann's letter to the Canadian Medical Association Journal: 1) defenders of abortion do not recommend abortion for fetuses that "may be deprived" of physical and emotional support; 2) a developing embryo is not a "human being" but rather a "potential" human being; 3) the concepts of Hoche and Binding did not directly lead to Nazi-inspired sterilizations and murders; 4) Hitler and Mussolini were staunch antiabortionists as well as proponents of euthanasia; 5) the recent drives for abortions and euthanasia derive from different sources; and 6) the term "proabortion" is misleading, as no supporter of abortion considers it a desirable act. This letter is then answered by Dr. Baunemann, who points out that Dr. Rapp has himself used the strawman argument, that a fetus is a human being with "potential", that Hitler's antiabortion stand stemmed from a desire for population increase, and that there is a connection between abortion and euthanasia.

    The possibility of weighting QALYs differently for different groups of patients has been a source of debate. Most recently, this debate has been extended to the relative value of QALYs at the end of life (EoL). The objective of this study is to provide evidence of societal preferences in relation to this topic. Three cross-sectional surveys were conducted amongst Spanish general population (n = 813). Survey 1 compared increases in life expectancy for EoL patients with health gains from temporary health problems. Survey 2 compared health gains for temporary health problems with quality of life gains at the EoL (palliative care). Survey 3 compared increases in life expectancy with quality of life gains, both for EoL patients. Preferences were elicited using Person Trade-Off (PTO) and Willingness to pay (WTP) techniques presenting two different durations of health benefit (6 and 18 months). Health benefits, measured in QALYs, were held constant in all comparisons. In survey 1 mean WTP was higher for life extending treatments than for temporary health problems and the majority of respondents prioritised life extension over temporary health problems in response to the PTO questions. In survey 2 mean WTP was higher for palliative care than for temporary health problems and 83% prioritized palliative care (for both durations) in the PTO questions. In survey 3 WTP values were higher for palliative care than for life extending treatments and more than 60% prioritized palliative care in the PTO questions. Our results suggest that QALYs gained from EoL treatments have a higher social value than QALYs gained from treatments for temporary health problems. Further, we found that people attach greater weight to improvements in quality of life than to life extension at the end of life. PMID:24820408

    Vaccines are effective tools to improve human health, but resources to pursue all vaccine-related investments are lacking. Benefit-cost and cost-effectiveness analysis are the two major methodological approaches used to assess the impact, efficiency, and distributional consequences of disease interventions, including those related to vaccinations. Childhood vaccinations can have important non-health consequences for productivity and economic well-being through multiple channels, including school attendance, physical growth, and cognitive ability. Benefit-cost analysis would capture such non-health benefits; cost-effectiveness analysis does not. Standard cost-effectiveness analysis may grossly underestimate the benefits of vaccines. A specific willingness-to-pay measure is based on the notion of the value of a statistical life (VSL), derived from trade-offs people are willing to make between fatality risk and wealth. Such methods have been used widely in the environmental and health literature to capture the broader economic benefits of improving health, but reservations remain about their acceptability. These reservations remain mainly because the methods may reflect ability to pay, and hence be discriminatory against the poor. However, willingness-to-pay methods can be made sensitive to income distribution by using appropriate income-sensitive distributional weights. Here, we describe the pros and cons of these methods and how they compare against standard cost-effectiveness analysis using pure health metrics, such as quality-adjusted life years (QALYs) and disability-adjusted life years (DALYs), in the context of vaccine priorities. We conclude that if appropriately used, willingness-to-pay methods will not discriminate against the poor, and they can capture important non-health benefits such as financial risk protection, productivity gains, and economic wellbeing.

    The magnitude of the value of a statistical life (VSL) is critical to the evaluation of many health and safety initiatives. To date, the large and rigorous VSL research literature has not explicitly accommodated publication selectivity bias (i.e., the reduced probability that insignificant or negative VSL values are reported). This study demonstrates that doing so is essential. For studies that employ hedonic wage equations to estimate VSL, correction for selection bias reduces the average value of a statistical life by 70-80%. Our meta-regression analysis also identifies several sources for the wide heterogeneity found among reported VSL estimates. PMID:22079490

    Workers at the oldest maternity hospital in Colombia experienced the privatization of health care and the flexibilization of their labor. Drawing on their experience, I illustrate how neoliberalism transforms the value of life. This transformation occurs first in terms of its moral worth: the worth of life changes over time, as people and public hospitals are stigmatized as the 'living memory' of the old. Second, the hospital buildings, the land on which they sit, and the roles of workers within the hospital are all transformed. Both similarities and differences emerge between a type of systemic or chronic violence that is inherent to the capitalist system and modern practices of torture. Examining how capitalist forces transform the value of life opens up new fields of inquiry to study links between critical political economy and subjectivity. PMID:26131618

    Little research has examined mean-level change in values across the life span. Using large cross-sectional data (N = 36,845) from the five geo-social regions in Brazil, this study examines how mean levels of basic values differ as a function of age (from age 12 to 65; M = 28) and whether age effects are moderated by gender. Results show that mean-level value change is substantial throughout the life course. We observed both linear and curvilinear patterns of change as well as differential patterns by gender. The observed value change is consistent with age-related life circumstances and psychosocial development. Age effects are also value dependent, supporting the notion that values have different functions for different developmental stages. PMID:26187119

    The concept of the person has come to be intimately connected with questions about the value of life. It is applied to those sorts of beings who have some special value or moral importance and where we need to prioritize the needs or claims of different sorts of individuals. "Person" is a concept designating individuals like us in some important respects, but possibly including individuals who are very unlike us in other respects. What are these respects and why are they important? This paper sets out to answer these questions and to develop a coherent and useful concept of the person. PMID:11657913

Veritivity, the main philosophical assumption of the Roy adaptation model, shapes it, and Roy's assumption of humanism in a unique way. Veritivity has a theocentric focus, with anthropological values. Roy views human beings as individuals in community with a loving Creator and with others. Truth, freedom, and moral ends are discussed in terms of veritivity and in terms of contemporary values. PMID:22753573

    2014-12-01

    All we know about life and our understanding of its distribution throughout the Universe is based on our understanding of how life originated and evolved, and how it has persisted here on Earth. As we have refined our list of requirements for earth-like organisms and explored the limits of our biosphere, a variety of possible extraterrestrial habitats that could support life have emerged. Although our access to other potentially habitable worlds is limited, we continue to increase our understanding of the environmental conditions on bodies in our solar system which can inform our search for appropriate analogue sites. There is no perfect analogue for other planetary habitable environments on Earth. Earth is a planet with plate tectonics, a hydrological cycle, a thick atmosphere and stronger gravity than most candidate systems. Moreover, present day Earth is a verdant, interconnected system resulting from billions of years of biosphere evolution. Such differences pose a challenge to analogue research and in particular limit the interpretation of the environment under study in important ways. Earth's extreme environments have been proposed as analogues of planetary environments. A common error is to assume if an environment is extreme or it is cold and dry it will make an excellent analogue site. The value of an analogue site is measured by a good assessment of the relevance of a site with rigorous attention to its Earth-based limitations is necessary and it will have different impacts depending on the question under study. Additionally, modern and ancient systems on earth can also be investigated in order to target a future search for as yet undetected terrestrial features and processes that preserve or indicate signs of past life. Despite any limitations, analogue research is essential and field research at these terrestrial sites represents a growing aspect of planetary science. Those relevant to the search for life are supported by NASA's Planetary Science, Technology through Analog Research (PSTAR).

    The requirement to reduce risk is moderated under British law by the notion of practicability or reasonable practicability. This implies that a balance should be struck, [ital inter alia], between the costs of a risk-reducing measure and its benefits in terms of life-saving and injury avoidance. Clearly, were lives and injuries valued in monetary terms, balances and imbalances would be all the more easily identified. This paper reports on progress on the application of the Relative Utility Loss Approach to the valuation of injuries in the consumer and transportation spheres in the United Kingdom. Although the tools are as yet imperfect, striking accord is noticed between evaluations of a range of serious and slight injuries obtained using three health state utility indices of disparate origin. 19 refs., 2 figs., 1 tab.

    2015-01-01

    Background In present-day life-insurance medical underwriting practice the risk assessment starts with a standard health declaration (SHD). Indication for additional medical screening depends predominantly on age and amount of insured capital. From a medical perspective it is questionable whether there is an association between the level of insured capital and medical risk in terms of mortality. The aim of the study is to examine the prognostic value of parameters from the health declaration and application form on extra mortality based on results from additional medical testing. Methods A history register-based cohort study was conducted including about 15.000 application files accepted between 2007 and 2010. Blood pressure, lipids, cotinine and glucose levels were used as dependent variables in logistic regression models. Resampling validation was applied using 250 bootstrap samples to calculate area under the curves (AUC’s). The AUC was used to discriminate between persons with and without at least 25% extra mortality. Results BMI and the overall assessment of the health declaration by an insurance physician or medical underwriter showed the strongest discrimination in multivariable analysis. Including all variables at minimum cut-off levels resulted in an AUC of 0.710 while by using a model with BMI, the assessment of the health declaration and gender, the AUC was 0.708. Including all variables at maximum cut-off levels lead to an AUC of 0.743 while a model with BMI, the assessment of the health declaration and age resulted in an AUC of 0.741. Conclusions The outcome of this study shows that BMI and the overall assessment of the health declaration were the dominant variables to discriminate between applicants for life-insurance with and without at least 25 percent extra mortality. The variable insured capital set by insurers as factor for additional medical testing could not be established in this study population. The indication for additional medical testing at underwriting life-insurance can possibly be done on limited variables instead of the obligatory medical testing based on age and the amount of insured capital.

    Purpose of the Study: To evaluate the extent to which religious affiliation and self-identified religious importance affect advance care planning (ACP) via beliefs about control over life length and end-of-life values. Design and Methods: Three hundred and five adults aged 55 and older from diverse racial and socioeconomic groups seeking outpatient care in New Jersey were surveyed. Measures included discussion of end-of-life preferences; living will (LW) completion; durable power of attorney for healthcare (DPAHC) appointment; religious affiliation; importance of religion; and beliefs about who/what controls life length, end-of-life values, health status, and sociodemographics. Results: Of the sample, 68.9% had an informal discussion and 46.2% both discussed their preferences and did formal ACP (LW and/or DPAHC). Conservative Protestants and those placing great importance on religion/spirituality had a lower likelihood of ACP. These associations were largely accounted for by beliefs about Gods controlling life length and values for using all available treatments. Implications: Beliefs and values about control account for relationships between religiosity and ACP. Beliefs and some values differ by religious affiliation. As such, congregations may be one nonclinical setting in which ACP discussions could be held, as individuals with similar attitudes toward the end of life could discuss their treatment preferences with those who share their views.

    Measurements at Isotope Products Laboratories (IPL) carried out with a hyper-pure germanium (HPGe) spectrometer have sought to improve upon the accepted half-life value for 95mTc. The uncertainty associated with the currently accepted value of (61+/-2) days allows for potentially significant improvement. Through a series of 65 measurements over the course of nearly 2 years, using multiple source-to-detector counting distances and multiple reference photopeaks, the authors have determined a half-life that agrees with the current value while reducing the uncertainty of the value by 25-fold.

    The fatality risk-money tradeoff that is the value of a statistical life (VSL) may vary with the nature of the fatality event. While all fatalities involve loss of future life expectancy, the morbidity effects and their duration may differ. This article analyzes fatality risks accompanied by morbidity effects of different duration to disentangle the mortality and morbidity components of VSL using data from the Census of Fatal Occupational Injuries (CFOI). The VSL is comprised of the sum of the value of the fatality risk and the value of the morbidity risk. Labor market valuations of morbidity risks are positive, even for fatalities that are caused by traumatic injuries. The value of the fatality risk is the dominant component of VSL, rather than the value of the morbidity risk. PMID:26896740

    1992-01-01

    Withdrawing life support is always difficult. When patients and health professionals are from different ethnic backgrounds, value systems that form the basis for such decisions may conflict. Many cultural groups do not place the same emphasis on patient autonomy and self-determination that Western society does and find the idea of terminating life support offensive. Although physicians should never assume patients will respond in a particular way because of their ethnic background, issues of life support should be discussed in a culturally sensitive way. African-American, Chinese, Jewish, Iranian, Filipino, Mexican-American, and Korean patients were surveyed about their views on life support. The findings reported here, although not meant to be definitive, should add to health professionals' understanding about diverse beliefs around life-and-death issues. By becoming aware of this diversity of beliefs, health professionals can avoid the damage to the physician-patient relationship caused by conflicting value systems. PMID:1413777

    2014-01-01

    Estimates of the value of a statistical life (VSL) establish the price government agencies use to value fatality risks. Transferring these valuations to other populations often utilizes the income elasticity of the VSL, which typically draw on estimates from meta-analyses. Using a data set consisting of 101 estimates of the income elasticity of VSL from 14 previously reported meta-analyses, we find that after accounting for potential publication bias the income elasticity of value of a statistical life is clearly and robustly inelastic, with a value of approximately 0.25-0.63. There is also clear evidence of the importance of controlling for levels of risk, differential publication selection bias, and the greater income sensitivity of VSL from stated preference surveys.

    PubMed Central

    Mortimer, Duncan; Segal, Leonie

    2008-01-01

    Background A number of recent findings imply that the value of a life saved, life-year (LY) saved or quality-adjusted life year (QALY) saved varies depending on the characteristics of the life, LY or QALY under consideration. Despite these findings, budget allocations continue to be made as if all healthy life-years are equivalent. This continued focus on simple health maximisation is partly attributable to gaps in the available evidence. The present study attempts to close some of these gaps. Methods Discrete choice experiment to estimate the marginal rate of substitution between cost, effectiveness and various non-health arguments. Odds of selecting profile B over profile A estimated via binary logistic regression. Marginal rates of substitution between attributes (including cost) then derived from estimated regression coefficients. Results Respondents were more likely to select less costly, more effective interventions with a strong evidence base where the beneficiary did not contribute to their illness. Results also suggest that respondents preferred prevention over cure. Interventions for young children were most preferred, followed by interventions for young adults, then interventions for working age adults and with interventions targeted at the elderly given lowest priority. Conclusion Results confirm that a trade-off exists between cost, effectiveness and non-health arguments when respondents prioritise health programs. That said, it is true that respondents were more likely to select less costly, more effective interventions confirming that it is an adjustment to, rather than an outright rejection of, simple health maximisation that is required.

    The closing address at the 1997 First International Conference on Healthcare Resource Allocation for HIV/AIDS and Other Life-Threatening Illnesses is presented. The address discusses the extrinsic value of life and the three forms of material value: spiritual, economic, and political, placed on life by an outside source. It is argued that if spiritual currency, rather than economic or political currency, drove public policy there would be greater progress in reducing the global rate of HIV and more options for care. Further, lack of identity of those afflicted with HIV reduces them to mere statistics, thus decreasing their economic and political clout. Giving identities to people who are sick not only increases empathy but also increases their survivability. The establishment of the Global Biography Project seeks to reestablish spiritual currency as the international currency that underlies every nation's healthcare policies. PMID:11364946

    Descriptive quality of life questionnaires are commonly administered in clinical trials, to evaluate outcomes from the patient's perspective alongside conventional clinical measures. When expressed in single index form as health state preference values (HSPVs), quality of life information is also relevant to economic evaluations. By combining HSPVs with survival information, quality adjusted life years (QALYs) may be derived for cost-utility analysis. Although HSPVs are rarely measured prospectively in cancer clinical trials, the UK Medical Research Council Cancer Therapy Committee recommends the routine administration of two specific quality of life questionnaires: the Rotterdam Symptom Checklist and the Hospital Anxiety Depression Scale. This study explores two potential methods for secondary derivation of HSPVs from these instruments, using data gathered in a clinical trial of two forms of radiotherapy for non-small cell cancer of the bronchus. The first method, secondary mapping to existing utility scales, was found to be infeasible from the above questionnaires. The second method used factor analysis to summarize the descriptive quality of life data collected through the questionnaires. This revealed five distinct factors prevalent in the trial population. Using these factors, simplified health state scenarios were developed from which direct measurement of HSPVs was feasible. As the resulting HSPVs and any QALYs that may be derived from them are cancer specific, their potential value in informing resource allocation would be limited to decisions within oncology services.

    Objectives To protect public health from risk, the Minister of Environment in Korea legislated an act concerning the registration and evaluation of chemical substances. In this study, we estimated the value of a statistical life (VSL) of carcinogenic chemicals to evaluate the socioeconomic analysis in Korea. Methods The estimation of the health benefit can be calculated through an individuals VSL and willingness to pay (WTP). To estimate the VSL and WTP, we used a contingent valuation method through a web-based survey. Results The survey is conducted with 1434 people living in Seoul and six large cities. An analysis of the survey is essential to review the distribution of the characteristics of the target population. The statistically significant variables affecting the WTP are location, age, household income, quality of life. Through the review of data, we secured statistical validity. The WTP was estimated as 41205 Korean won (KRW)/person, and the estimated VSL appeared as 796 million KRW/person. Conclusions There is a case in which the amount of statistical life value is estimated in connection with domestic environmental policy, fine dust, etc. However, there are no cases of evaluation for chemical. The utilization of this result is possible for conducting other study with chemicals. PMID:26206366

  20. Decomposing cross-country differences in quality adjusted life expectancy: the impact of value sets

    PubMed Central

    2011-01-01

    Background The validity, reliability and cross-country comparability of summary measures of population health (SMPH) have been persistently debated. In this debate, the measurement and valuation of nonfatal health outcomes have been defined as key issues. Our goal was to quantify and decompose international differences in health expectancy based on health-related quality of life (HRQoL). We focused on the impact of value set choice on cross-country variation. Methods We calculated Quality Adjusted Life Expectancy (QALE) at age 20 for 15 countries in which EQ-5D population surveys had been conducted. We applied the Sullivan approach to combine the EQ-5D based HRQoL data with life tables from the Human Mortality Database. Mean HRQoL by country-gender-age was estimated using a parametric model. We used nonparametric bootstrap techniques to compute confidence intervals. QALE was then compared across the six country-specific time trade-off value sets that were available. Finally, three counterfactual estimates were generated in order to assess the contribution of mortality, health states and health-state values to cross-country differences in QALE. Results QALE at age 20 ranged from 33 years in Armenia to almost 61 years in Japan, using the UK value set. The value sets of the other five countries generated different estimates, up to seven years higher. The relative impact of choosing a different value set differed across country-gender strata between 2% and 20%. In 50% of the country-gender strata the ranking changed by two or more positions across value sets. The decomposition demonstrated a varying impact of health states, health-state values, and mortality on QALE differences across countries. Conclusions The choice of the value set in SMPH may seriously affect cross-country comparisons of health expectancy, even across populations of similar levels of wealth and education. In our opinion, it is essential to get more insight into the drivers of differences in health-state values across populations. This will enhance the usefulness of health-expectancy measures.

    2009-03-01

    The value of a statistical life (VSL) is a very controversial topic, but one which is essential to the optimization of governmental decisions. We see a great variability in the values obtained from different studies. The source of this variability needs to be understood, in order to offer public decision-makers better guidance in choosing a value and to set clearer guidelines for future research on the topic. This article presents a meta-analysis based on 39 observations obtained from 37 studies (from nine different countries) which all use a hedonic wage method to calculate the VSL. Our meta-analysis is innovative in that it is the first to use the mixed effects regression model [Raudenbush, S.W., 1994. Random effects models. In: Cooper, H., Hedges, L.V. (Eds.), The Handbook of Research Synthesis. Russel Sage Foundation, New York] to analyze studies on the value of a statistical life. We conclude that the variability found in the values studied stems in large part from differences in methodologies. PMID:19100640

  4. Double impact of sterilizing pathogens: added value of increased life expectancy on pest control effectiveness.

    2012-06-01

    Sterilizing pathogens are commonly assumed not to affect longevity of infected individuals, and if they do then negatively. Examples abound, however, of species in which the absence of reproduction actually increases life expectancy. This happens because by decreasing the energy outlay on reproduction individuals with lowered reproduction can live longer. Alternatively, fertile individuals are more susceptible to predators or parasitoids if the latter can capitalize on mating signals of the former. Here we develop and analyze an SI epidemiological model to explore whether and to what extent does such a life expectancy prolongation due to sterilizing pathogens affect host dynamics. In particular, we are interested in an added value of increased life expectancy on the possibility of successful pest control, that is, the effect of increased lifespan and hence increased potential of the infected individuals to spread the disease on pest control effectiveness. We show that although the parameter range in which we observe an effect of increased lifespan of the sterilized individuals is not large, the effect itself can be significant. In particular, the increase in pest control effectiveness can be very dramatic when disease transmission efficiency is close to birth rate, mortality rate of susceptibles is relatively high (i.e.,the species is relatively short-lived), and sterilization efficiency is relatively high. Our results thus characterize pathogens that are promising candidates for an effective pest control and that might possibly be engineered if not occurring naturally. PMID:21710138

    Background There are numerous health-related quality of life (HRQol) measurements used in coronary heart disease (CHD) in the literature. However, only values assessed with preference-based instruments can be directly applied in a cost-utility analysis (CUA). Objective To summarize and synthesize instrument-specific preference-based values in CHD and the underlying disease-subgroups, stable angina and post-acute coronary syndrome (post-ACS), for developed countries, while accounting for study-level characteristics, and within- and between-study correlation. Methods A systematic review was conducted to identify studies reporting preference-based values in CHD. A multivariate meta-analysis was applied to synthesize the HRQoL values. Meta-regression analyses examined the effect of study level covariates age, publication year, prevalence of diabetes and gender. Results A total of 40 studies providing preference-based values were detected. Synthesized estimates of HRQoL in post-ACS ranged from 0.64 (Quality of Well-Being) to 0.92 (EuroQol European”tariff”), while in stable angina they ranged from 0.64 (Short form 6D) to 0.89 (Standard Gamble). Similar findings were observed in estimates applying to general CHD. No significant improvement in model fit was found after adjusting for study-level covariates. Large between-study heterogeneity was observed in all the models investigated. Conclusions The main finding of our study is the presence of large heterogeneity both within and between instrument-specific HRQoL values. Current economic models in CHD ignore this between-study heterogeneity. Multivariate meta-analysis can quantify this heterogeneity and offers the means for uncertainty around HRQoL values to be translated to uncertainty in CUAs. PMID:27011260

    Tracking performance of life insurance or similar insurance policy using standard statistical process control chart is complex because of many factors. In this work, we present the difficulty in doing so. However, with some modifications of the SPC charting framework, the difficulty can be manageable to the actuaries. So, we propose monitoring a simpler but natural actuarial quantity that is typically found in recursion formulas of reserves, profit testing, as well as present values. We shared some simulation results for the monitoring process. Additionally, some advantages of doing so is discussed.

    2015-01-01

    It is generally understood that happiness is an important goal of dementia care, though evaluation has been challenging. Concerns about cognitive and communicative limitations have led to the use of proxy reports to assess positive affect. However, proxy reports have been shown to differ from appraisals obtained by the person with Alzheimer's disease (AD). This article reports on a qualitative study of happiness in a sample of 12 persons with mild to moderate AD using photo-elicitation and individual interviews for data collection. Results demonstrate people with mild to moderate AD can provide meaningful evaluations of happiness, and that lifelong values continue to be important in the presence of AD. This study suggests photographs may offer a novel approach to obtain a contextualized understanding of happiness and other values in this population which may lead to the development of person centered interventions aimed to improve the individual's quality of life.

    Richardson, J

    1987-07-01

    The author, an economist, rebuts the contention that human life cannot and should not be economically evaluated and argues that such evaluations are made implicitly and inconsistently, resulting in a reduction of human welfare. He presents an economic framework for the analysis of costs and benefits in which the focal point, as in most value systems, is the tradeoff between life and quality of life. Therefore, as the quality of life decreases, society's efforts to preserve life should decrease. If the valuation of life includes self evaluation, then there should be less effort to preserve the life of an individual who wishes to die. Richardson concludes that voluntary euthanasia is a limiting case in which society accepts the individual's valuation of life. PMID:11651869

    1999-01-01

    The NASA Advanced Life Support (ALS) Program is required to provide a performance metric to measure its progress in system development. Extensive discussions within the ALS program have reached a consensus. The Equivalent System Mass (ESM) metric has been traditionally used and provides a good summary of the weight, size, and power cost factors of space life support equipment. But ESM assumes that all the systems being traded off exactly meet a fixed performance requirement, so that the value and benefit (readiness, performance, safety, etc.) of all the different systems designs are exactly equal. This is too simplistic. Actual system design concepts are selected using many cost and benefit factors and the system specification is then set accordingly. The ALS program needs a multi-parameter metric including both the ESM and a System Value Metric (SVM). The SVM would include safety, maintainability, reliability, performance, use of cross cutting technology, and commercialization potential. Another major factor in system selection is technology readiness level (TRL), a familiar metric in ALS. The overall ALS system metric that is suggested is a benefit/cost ratio, [SVM + TRL]/ESM, with appropriate weighting and scaling. The total value is the sum of SVM and TRL. Cost is represented by ESM. The paper provides a detailed description and example application of the suggested System Value Metric.

    The monetized value of avoided premature mortality typically dominates the calculated benefits of air pollution regulations; therefore, characterization of the uncertainty surrounding these estimates is key to good policymaking. Formal expert judgment elicitation methods are one means of characterizing this uncertainty. They have been applied to characterize uncertainty in the mortality concentration-response function, but have yet to be used to characterize uncertainty in the economic values placed on avoided mortality. We report the findings of a pilot expert judgment study for Health Canada designed to elicit quantitative probabilistic judgments of uncertainties in Value-per-Statistical-Life (VSL) estimates for use in an air pollution context. The two-stage elicitation addressed uncertainties in both a base case VSL for a reduction in mortality risk from traumatic accidents and in benefits transfer-related adjustments to the base case for an air quality application (e.g., adjustments for age, income, and health status). Results for each expert were integrated to develop example quantitative probabilistic uncertainty distributions for VSL that could be incorporated into air quality models. PMID:22571466

    Objective To identify the prevalence of disability in a wide range of life activities and identify factors associated with such disability using the Verbrugge and Jette disablement model as a framework. Methods Data were from a panel study of 548 individuals with rheumatoid arthritis, interviewed annually by telephone. Valued life activity (VLA) disability was assessed using a 26?item scale rating difficulty in carrying out each activity. Three types of summary measure were calculated: activities unable to perform, activities affected, and mean difficulty. Subscale scores were also calculated, corresponding to obligatory, committed, and discretionary activities, as defined in the disablement model. Disease status measures were examined as predictors of VLA disability using multiple regression analyses. Results Half the subjects were unable to do at least one VLA. Approximately 2%, 31.3%, and 40.2% were unable to do at least one obligatory, committed, and discretionary activity, respectively. Almost all (95%) reported at least one VLA affected by rheumatoid arthritis; 68.4%, 91.4%, and 92.5% reported at least one obligatory, committed, and discretionary activity, respectively, affected. Disease status measures were robust predictors of VLA disability, accounting for 2247% of the variation in VLA disability (with one exception). Adding the health assessment questionnaire (HAQ) to these models increased (p<0.0001) all model R2 values. HAQ score mediated the effects of many disease measures, consistent with the disablement model. Conclusion VLA disability was common, with more disability noted in committed and discretionary than obligatory activities. Because VLA disability has been linked to psychological wellbeing in previous studies, identification of factors that may protect against such disability is important. PMID:16249225

    PubMed

    Link, Hans-Jrgen

    2013-06-01

    Most of the reports on synthetic biology include not only familiar topics like biosafety and biosecurity but also a chapter on 'ethical concerns'; a variety of diffuse topics that are interrelated in some way or another. This article deals with these 'ethical concerns'. In particular it addresses issues such as the intrinsic value of life and how to deal with 'artificial life', and the fear that synthetic biologists are tampering with nature or playing God. Its aim is to analyse what exactly is the nature of the concerns and what rationale may lie behind them. The analysis concludes that the above-mentioned worries do not give genuine cause for serious concern. In the best possible way they are interpreted as slippery slope arguments, yet arguments of this type need to be handled with care. It is argued that although we are urged to be especially vigilant we do not have sufficiently cogent reasons to assume that synthetic biology will cause such fundamental hazards as to warrant restricting or refraining from research in this field.

    In January 2009, Britain's National Institute for Health and Clinical Excellence (NICE), following a very public debate triggered by its decision, six months earlier, provisionally to rule against the adoption by the National Health Service (NHS) of an expensive drug for advanced renal cancer, introduced a new policy for evaluating pharmaceuticals for patients nearing the end of their lives. NICE's so-called end-of-life (EOL) guidance for its Committees effectively advises them to deviate from the Institute's threshold range and to value the lives of (mostly) dying cancer patients more than the lives of those suffering from other, potentially curable, chronic or acute conditions. This article tells the story of the EOL guidance. Through looking at specific EOL decisions between 2009 and 2011 and the reactions by stakeholders to these decisions and the policy itself, it discusses the triggers for NICE's EOL guidance, the challenges NICE faces in implementing it and the policy's putative implications for the future role of NICE in the NHS, especially in the context of value-based reforms in the pricing and evaluation of pharmaceuticals, currently under consideration.

    Permanent magnets containing rare earth elements (REEs) such as Dysprosium and Neodymium offer an advantage over non-REE containing magnets (e.g., ferrite and AlNiCo) in terms of power relative to size. However, REE availability has varied significantly in recent years leading to volatility in the cost of rare earth permanent magnets (REPMs). The supply of REEs can be increased by recycling consumer products and industrial machinery that contain REPMs at product end-of-life (EOL). This paper discusses the REE recovery process for EOL products. The optimal dismantling of products is examined with an emphasis placed on obtaining used REPMs. The challenge of collecting, managing, transporting, and processing used products is addressed through the development of a cost model for REPM recovery. This model is used to investigate several EOL strategies for recovering REPMs. Sensitivity analysis is conducted to identify the key factors that influence value recovery economics. A hard disk drive serves as a case study for model demonstration.

    Reproduction in social organisms is shaped by numerous morphological, behavioural and life-history traits such as body size, cooperative breeding and age of reproduction, respectively. Little is known, however, about the relative influence of these different types of traits on reproduction, particularly in the context of environmental conditions that determine their adaptive value. Here, we use 14 years of data from a long-term study of wolves (Canis lupus) in Yellowstone National Park, USA, to evaluate the relative effects of different traits and ecological factors on the reproductive performance (litter size and survival) of breeding females. At the individual level, litter size and survival improved with body mass and declined with age (c. 4-5 years). Grey-coloured females had more surviving pups than black females, which likely contributed to the maintenance of coat colour polymorphism in this system. The effect of pack size on reproductive performance was nonlinear as litter size peaked at eight wolves and then declined, and litter survival increased rapidly up to three wolves, beyond which it increased more gradually. At the population level, litter size and survival decreased with increasing wolf population size and canine distemper outbreaks. The relative influence of these different-level factors on wolf reproductive success followed individual > group > population. Body mass was the primary determinant of litter size, followed by pack size and population size. Body mass was also the main driver of litter survival, followed by pack size and disease. Reproductive gains because of larger body size and cooperative breeding may mitigate reproductive losses because of negative density dependence and disease. These findings highlight the adaptive value of large body size and sociality in promoting individual fitness in stochastic and competitive environments. PMID:23043440

    Objective To describe the prevalence of using 4 specific behavioral accommodations (assistive devices, personal assistance, limits on the amount or kind of activities, and taking more time to perform activities) in the performance of valued life activities (VLAs), and to examine the impact of accounting for these accommodations on VLA disability scores. Methods Data were from a panel study of 467 individuals with rheumatoid arthritis (RA) interviewed annually by telephone. VLA disability was assessed using a 29-item scale, rating difficulty performing each activity and asking whether the 4 types of accommodations were used. An unadjusted difficulty score based solely on difficulty ratings was calculated, as well as 3 adjusted scores accounting for use of assistance or devices, use of assistance, devices, or limitations in activities, and use of all 4 accommodations. Results Accommodations were widely used by individuals with RA to perform daily activities. Limits and more time were used for more activities than assistance and devices. Adjustment for accommodations produced substantial increases in disability scores (e.g., the mean total VLA difficulty score increased by 84% after adjustment for all 4 accommodations). Conclusion The accommodations included on the Health Assessment Questionnaire, the most commonly used measure of functioning for RA, include only assistive devices and personal assistance, which were not the accommodations most frequently used in our sample. If assessments are intended to estimate total disease burden, they should include use of a broader range of accommodations to develop a more complete picture of how daily function is affected.

    We examined elevated mortality rates in Appalachian coal mining areas for 1979-2005, and estimated the corresponding value of statistical life (VSL) lost relative to the economic benefits of the coal mining industry. We compared age-adjusted mortality rates and socioeconomic conditions across four county groups: Appalachia with high levels of coal mining, Appalachia with lower mining levels, Appalachia without coal mining, and other counties in the nation. We converted mortality estimates to VSL estimates and compared the results with the economic contribution of coal mining. We also conducted a discount analysis to estimate current benefits relative to future mortality costs. The heaviest coal mining areas of Appalachia had the poorest socioeconomic conditions. Before adjusting for covariates, the number of excess annual age-adjusted deaths in coal mining areas ranged from 3,975 to 10,923, depending on years studied and comparison group. Corresponding VSL estimates ranged from $18.563 billion to $84.544 billion, with a point estimate of $50.010 billion, greater than the $8.088 billion economic contribution of coal mining. After adjusting for covariates, the number of excess annual deaths in mining areas ranged from 1,736 to 2,889, and VSL costs continued to exceed the benefits of mining. Discounting VSL costs into the future resulted in excess costs relative to benefits in seven of eight conditions, with a point estimate of $41.846 billion.

Unfortunately, the nutritionally enriched pulp of ripened palm has limited commercial use. Extraction of pulp has been accomplished by using water and heat to ensure maximum pulp recovery. Different recipes were tried for the preparation of two uncommon value added products like palm spread and palm toffee. On the basis of biochemical composition, organoleptic scores, microbial estimation and storage study both under ambient and refrigerated conditions; the suitable recipe was selected with the maximum acceptability. Gradual increase in total soluble solid (TSS), total sugar and reducing sugar while decrease in ascorbic acid, pH, β-carotene and protein content of processed products have been observed irrespective of storage condition. The results obtained from sensory evaluation and microbial status revealed that palm spread and toffee remained acceptable up to 9 months and 8 months, respectively at ambient temperature. The income per rupee investment for these two products was found to be remunerative. PMID:24741173

  5. The value of 'life at any cost': Talk about stopping kidney dialysis

    With the trend toward an older, sicker dialysis population in the USA, discussions of ethical issues surrounding dialysis have shifted from concerns about access to and availability of the therapy, to growing unease about non-initiation and treatment discontinuation. Recent studies report treatment withdrawal as the leading cause of death among elderly dialysis patients. Yet, the actual activities that move patients toward stopping treatment often remain obscure, even to clinicians and patients themselves. This paper explores that paradox, drawing on anthropological research among patients over age 70, their families, and clinicians in two California renal dialysis units. It concludes that many older patients sacrifice a sense of choice about dialysis in the present to maintain “choice” as both value and possibility for the future. Yet, patients desire more information and communication, provided earlier in their illness, about prognosis, how long they can expect to be on dialysis, and what the impact of the treatment will be on their daily lives. That, with time, there is a transition to be made from dialysis as “treatment” to end of life care could be better explained and managed to alleviate patients’ confusion and unneeded isolation.

    Background Influenza vaccination is administered throughout the influenza disease season, even as late as March. Given such timing, what is the value of vaccinating the population earlier than currently being practiced? Methods We used real data on when individuals were vaccinated in Allegheny County, Pennsylvania, and the following 2 models to determine the value of vaccinating individuals earlier (by the end of September, October, and November): Framework for Reconstructing Epidemiological Dynamics (FRED), an agent-based model (ABM), and FluEcon, our influenza economic model that translates cases from the ABM to outcomes and costs [health care and lost productivity costs and quality-adjusted life-years (QALYs)]. We varied the reproductive number (R0) from 1.2 to 1.6. Results Applying the current timing of vaccinations averted 223,761 influenza cases, $16.3 million in direct health care costs, $50.0 million in productivity losses, and 804 in QALYs, compared with no vaccination (February peak, R0 1.2). When the population does not have preexisting immunity and the influenza season peaks in February (R0 1.2–1.6), moving individuals who currently received the vaccine after September to the end of September could avert an additional 9634–17,794 influenza cases, $0.6–$1.4 million in direct costs, $2.1–$4.0 million in productivity losses, and 35–64 QALYs. Moving the vaccination of just children to September (R0 1.2–1.6) averted 11,366–1660 influenza cases, $0.6–$0.03 million in direct costs, $2.3–$0.2 million in productivity losses, and 42–8 QALYs. Moving the season peak to December increased these benefits, whereas increasing preexisting immunity reduced these benefits. Conclusion Even though many people are vaccinated well after September/October, they likely are still vaccinated early enough to provide substantial cost-savings. PMID:25590676

    Motorcyclists constitute a large proportion of total road casualties in Asian countries Unfortunately, studies conducted for the purpose of evaluating the cost of traffic crashes, and cost-benefit analyses of safety interventions, are almost nonexistent in these countries. The loss-of-output approach to valuing life has been used for many years, yet this method has also long been criticised as it results in significant resource misallocation. This study attempts to overcome this problem by estimating the value of a statistical life among motorcyclists using the willingness-to-pay method that is commonly used in developed countries. The study recommends adopting a value of MYR1.1 million (almost five times the previous estimate) per statistical life for public policy analysis involving motorcycle safety. PMID:15702934

    This article describes a potential way of counseling emerging adults from a life design perspective to construct a self that could enable them to be agents of both their own development and the development of others. Theoretical issues relating to a dynamic, developmental and systems framework of the understanding of wellbeing are described and the process involved is delineated. The research design was qualitative and comprised case studies. Six participants who subscribed to the definition of "emerging adults" and were comparatively representative of the ethnic diversity of South Africa, were selected purposively from a group of individuals who applied for career counseling in a private practice context. The intervention involved life design counseling and occurred over a period of 6 weeks. Information related to participants' self-construction was gathered using qualitative techniques, including the Career Interest Profile, the Career Construction Interview, a timeline, video clips, a collage, and semi-structured interviews. Following the intervention, the participants revealed heightened insights with regard to aspects of their sense of a relational-moral self. Results indicated that life design counseling could enhance elaborative personal development (enhancing self-awareness and reaping the benefits of developing an improved relational-moral self) and the promotion of an awareness of the importance to promote social justice in work-related contexts.

    The use of administrative data is common practice in public health research. The present field note describes the Continuous Working Life Sample (CWLS) and its use in health research. The CWLS is built on records generated by all contacts with the social security system (work contracts, disability, etc.), plus tax data (monetary gains, income, etc.) and census data (level of education, country of birth, etc.), but does not allow individuals to be identified. The CWLS was started in 2004 with 4% (1.1 million persons) of the total population who were either contributors to or beneficiaries of the social security system. The information on the individuals in the CWLS is updated annually and lost individuals are replaced. This continuous design allows the construction of a cohort with information on working life and financial status and evaluation of their relationship with work disability. Future connection with clinical records would enable analysis of other health-related outcomes. PMID:24698033

  2. New value packing technology extends service life

    1993-10-01

    New packing techniques can extend packing life and retain low stem leakage. The HPI can use these designs to avoid mandatory monitoring and repair schedules for valves that exceed the 500-ppm emission threshold. New EPA leakage limits will enforce monitoring and maintenance programs if more than 2% of the facility's valves exceed this limit. Because valves are dynamic, their control actions are prone to leakage. Also, the best fire-resistant packing material, graphite, has inherent deficiencies such as high compression stress and a high-friction coefficient that shortens its service life. Four basic principles overcome graphite packing's shortcomings for control valve applications. Examples show how these criteria improve sliding stem and rotary valve performance. Incorporating these principles into valve-packing designs can ensure long, low-maintenance service life, and the added benefit of low leakage. Graphite is a very important packing material for the HPI. Unlike fluoropolymer (e.g., PTFE) packing, graphite can tolerate high process temperature without decomposing or losing its sealing properties. More importantly, graphite packing is fire safe. It can survive a fire without a catastrophic failure that could add more flammable materials.

  3. Is valuing positive emotion associated with life satisfaction?

    PubMed

    Bastian, Brock; Kuppens, Peter; De Roover, Kim; Diener, Ed

    2014-08-01

    The experience of positive emotion is closely linked to subjective well-being. For this reason, campaigns aimed at promoting the value of positive emotion have become widespread. What is rarely considered are the cultural implications of this focus on happiness. Promoting positive emotions as important for "the good life" not only has implications for how individuals value these emotional states, but for how they believe others around them value these emotions also. Drawing on data from over 9,000 college students across 47 countries we examined whether individuals' life satisfaction is associated with living in contexts in which positive emotions are socially valued. The findings show that people report more life satisfaction in countries where positive emotions are highly valued and this is linked to an increased frequency of positive emotional experiences in these contexts. They also reveal, however, that increased life satisfaction in countries that place a premium on positive emotion is less evident for people who tend to experience less valued emotional states: people who experience many negative emotions, do not flourish to the same extent in these contexts. The findings demonstrate how the cultural value placed on certain emotion states may shape the relationship between emotional experiences and subjective well-being. PMID:24749643

    The purpose of the study was to examine whether psychosocial and spiritual well-being is associated with African-American dialysis patients' end-of-life treatment preferences and acceptance of potential outcomes of life sustaining treatment. Fifty-one African Americans with end stage renal disease (ESRD) completed a socio-demographic questionnaire and interview with measures of symptom distress, health-related quality of life, psychosocial and spiritual well-being, and preferences and values related to life sustaining treatment choices. The subjects were stratified by end-of-life treatment preferences and by acceptance of life sustaining treatment outcomes and compared for psychosocial and spiritual well-being as well as socio-demographic and clinical characteristics. Individuals who desired continued use of life sustaining treatment in terminal illness or advanced dementia had significantly lower spiritual well-being (p = .012). Individuals who valued four potential outcomes of life sustaining treatment as unacceptable showed a more positive, adaptive well-being score in the spiritual dimension compared to the group who valued at least one outcome as acceptable (p = .028). Religious involvement and importance of spirituality were not associated with end-of-life treatment preferences and acceptance of treatment outcomes. African Americans with ESRD expressed varied levels of psychosocial and spiritual well-being, and this characteristic was associated with life sustaining treatment preferences. In future research, the assessment of spirituality should not be limited to its intensity or degree but extended to other dimensions. PMID:19356896

    In the state of South Australia, infants with myelodysplasia have been treated by early intervention since 1963, and the majority have survived. Many are now adults, leading active lives despite having severe disabilities. A pilot study confirmed that this population has a high incidence of preventable ill health because of recurrent urinary infections, renal damage, and pressure ulcers. Many of these complications can be prevented by an outreach nursing service aimed at providing education in self-care, counseling, advocacy, and other appropriate nursing interventions, thus allowing clients to avoid hospitalization and maintain their independence. The study also showed that many clients were unaware of important social benefits, the knowledge of which should promote their financial independence. The outreach nursing service is an essential part of an integrated long-term support program for adults with myelodysplasia and other forms of congenital spinal paralysis. PMID:9832916

  3. Cadmium risks to freshwater life: derivation and validation of low-effect criteria values using laboratory and field studies

    USGS Publications Warehouse

    Mebane, Christopher A.

    2006-01-01

    In 2001, the U.S. Environmental Protection Agency (EPA) released updated aquatic life criteria for cadmium. Since then, additional data on the effects of cadmium to aquatic life have become available from studies supported by the EPA, Idaho Department of Environmental Quality (IDEQ), and the U.S. Geological Survey, among other sources. Updated data on the effects of cadmium to aquatic life were compiled and reviewed and low-effect concentrations were estimated. Low-effect values were calculated using EPA's guidelines for deriving numerical national water-quality criteria for the protection of aquatic organisms and their uses. Data on the short-term (acute) effects of cadmium on North American freshwater species that were suitable for criteria derivation were located for 69 species representing 57 genera and 33 families. For longer-term (chronic) effects of cadmium on North American freshwater species, suitable data were located for 28 species representing 21 genera and 17 families. Both the acute and chronic toxicity of cadmium were dependent on the hardness of the test water. Hardness-toxicity regressions were developed for both acute and chronic datasets so that effects data from different tests could be adjusted to a common water hardness. Hardness-adjusted effects values were pooled to obtain species and genus mean acute and chronic values, which then were ranked by their sensitivity to cadmium. The four most sensitive genera to acute exposures were, in order of increasing cadmium resistance, Oncorhynchus (Pacific trout and salmon), Salvelinus ('char' trout), Salmo (Atlantic trout and salmon), and Cottus (sculpin). The four most sensitive genera to chronic exposures were Hyalella (amphipod), Cottus, Gammarus (amphipod), and Salvelinus. Using the updated datasets, hardness dependent criteria equations were calculated for acute and chronic exposures to cadmium. At a hardness of 50 mg/L as calcium carbonate, the criterion maximum concentration (CMC, or 'acute' criterion) was calculated as 0.75 mug/L cadmium using the hardness-dependent equation CMC = e(0.8403 ? ln(hardness)-3.572) where the 'ln hardness' is the natural logarithm of the water hardness. Likewise, the criterion continuous concentration (CCC, or 'chronic' criterion) was calculated as 0.37 mug/L cadmium using the hardness-dependent equation CCC = (e(0.6247 ? ln(hardness)-3.384)) ? (1.101672 - ((ln hardness) ? 0.041838))). Using data that were independent of those used to derive the criteria, the criteria concentrations were evaluated to estimate whether adverse effects were expected to the biological integrity of natural waters or to selected species listed as threatened or endangered. One species was identified that would not be fully protected by the derived CCC, the amphipod Hyalella azteca. Exposure to CCC conditions likely would lead to population decreases in Hyalella azteca, the food web consequences of which probably would be slight if macroinvertebrate communities were otherwise diverse. Some data also suggested adverse behavioral changes are possible in fish following long-term exposures to low levels of cadmium, particularly in char (genus Salvelinus). Although ambiguous, these data indicate a need to periodically review the literature on behavioral changes in fish following metals exposure as more information becomes available. Most data reviewed indicated that criteria conditions were unlikely to contribute to overt adverse effects to either biological integrity or listed species. If elevated cadmium concentrations that approach the chronic criterion values occur in ambient waters, careful biological monitoring of invertebrate and fish assemblages would be prudent to validate the prediction that the assemblages would not be adversely affected by cadmium at criterion concentrations.

    Landslide and flood events in Italy cause wide and severe damage to buildings and infrastructure, and are frequently involved in the loss of human life. The cost estimates of past natural disasters generally refer to the amount of public money used for the restoration of the direct damage, and most commonly do not account for all disaster impacts. Other cost components, including indirect losses, are difficult to quantify and, among these, the cost of human lives. The value of specific human life can be identified with the value of a statistical life (VLS), defined as the value that an individual places on a marginal change in their likelihood of death This is different from the value of an actual life. Based on information of fatal car accidents in Italy, we evaluate the cost that society suffers for the loss of life due to landslide and flood events. Using a catalogue of fatal landslide and flood events, for which information about gender and age of the fatalities is known, we determine the cost that society suffers for the loss of their life. For the purpose, we calculate the economic value in terms of the total income that the working-age population involved in the fatal events would have earned over the course of their life. For the computation, we use the pro-capita income calculated as the ratio between the GDP and the population value in Italy for each year, since 1980. Problems occur for children and retired people that we decided not to include in our estimates.

  5. Quality-of-life measures as providers of information on value-for-money of health interventions. Comparison and recommendations for practice.

    Three different approaches to measuring quality of life have been developed. Global scales (e.g. time trade-off, visual analogue), multi-attribute utility scales and multidimensional scales (which may be generic or disease-specific). Each of these approaches to measurement provides different kinds of information about quality of life and each can be used to provide information to healthcare purchasers concerning the relative value-for-money of health interventions. The value-for-money of health interventions, in terms of quality of life, can be demonstrated in 2 ways: a formula-driven approach based on cost-utility analysis, which uses scales generating the unit of a quality-adjusted life-year (i.e. global and multi-attribute utility); and a non-formula-driven approach, which uses scales generating multidimensional profiles of quality of life (i.e. multi-attribute utility and multidimensional). Analysis shows that no single approach is sufficient, and that healthcare purchasers should use a variety of types of information in their decision-making, including both cost-utility and informal approaches. Healthcare resource allocation is inevitably a value-dependent activity. PMID:10172916

  6. Cost-benefit analysis of ambulance and rescue helicopters in Norway: reflections on assigning a monetary value to saving a human life.

    2002-01-01

    This paper reports the results of a cost-benefit analysis undertaken in 1996 for a public commission set up to plan the future operation of state-owned ambulance and rescue helicopters in Norway. The analysis indicates that the benefits of ambulance missions flown by helicopters exceeds the costs by a factor of almost six. To do this analysis it was necessary to assign a monetary value to human life. Traditionally this has not been done in medicine, and may be widely regarded as inconsistent with medical ethics. The results of the cost-benefit analysis serve as the starting point to a more general discussion surrounding the economic value of activities designed to reduce human mortality. It is concluded that human preferences for the provision of health care or other life-saving interventions are probably too complex to be adequately represented by means of a single monetary value expressing the benefits of life-saving. The task of developing an inclusive framework for a normative approach to priority setting in injury prevention is daunting, and may be insoluble. It is important to assess the extent to which current value-of-life estimates depend on study methods and social context. PMID:14619252

    Pollination improves the yield of most crop species and contributes to one-third of global crop production, but comprehensive benefits including crop quality are still unknown. Hence, pollination is underestimated by international policies, which is particularly alarming in times of agricultural intensification and diminishing pollination services. In this study, exclusion experiments with strawberries showed bee pollination to improve fruit quality, quantity and market value compared with wind and self-pollination. Bee-pollinated fruits were heavier, had less malformations and reached higher commercial grades. They had increased redness and reduced sugar-acid-ratios and were firmer, thus improving the commercially important shelf life. Longer shelf life reduced fruit loss by at least 11%. This is accounting for 0.32 billion US$ of the 1.44 billion US$ provided by bee pollination to the total value of 2.90 billion US$ made with strawberry selling in the European Union 2009. The fruit quality and yield effects are driven by the pollination-mediated production of hormonal growth regulators, which occur in several pollination-dependent crops. Thus, our comprehensive findings should be transferable to a wide range of crops and demonstrate bee pollination to be a hitherto underestimated but vital and economically important determinant of fruit quality.

    Background The understanding of the values of nurses is especially important, since nurses constitute 80% of workforce in the healthcare system in Lithuania. In addition to that, nursing is one of the major constituents of healthcare. The aim of this study was to determine what values predominate in the cohort of Baby Boomer nurses, and to evaluate the relation of these values with quality of life using M. Rokeach's terminal and instrumental values scale. M.Rokeach distinguished terminal values (such as world peace, wisdom, and happiness), which are preferred end-states of existence, and instrumental values (such as responsibility and cooperation), which are preferred modes of conduct. Methods We performed a representative anonymous questionnaire-based inquiry of nurses working in regional hospitals of Lithuania. The nurses who participated in the study were distributed into four work cohorts: the Veterans, the Baby Boomers, the Generation Xers, and the Generation Nexters. The majority of the nurses belonged to the Baby Boomers and the Generation Xers cohorts. Since in Lithuania, like in the whole Europe, the representatives of the Baby Boomers generation are predominating among working people, we selected this cohort (N = 387) for the analysis. The survey data was processed using the SPSS statistical software package Results The main values in life were family security, tranquility, and a sense of accomplishment. However, such values as true friendship, equality, and pleasurable and leisured life were seen as rather insignificant. The most important instrumental values were honesty, skillfulness, and responsibility. Our study showed a statistically significant (albeit weak) correlation between the QOL and terminal values such as the sense of accomplishment, tranquility, equality, and pleasure, as well as the instrumental value – obedience. We detected a statistically significant relationship between good QOL and satisfaction with oneself, relationships with the surrounding people, and friends' support. Conclusion The findings of our study showed that, although Lithuania was under a totalitarian regime for 50 years, both the terminal and the instrumental values of the Baby Boomers generation are very similar to those of the same generation in other countries.

    The value of small changes in mortality risk, conventionally expressed as the value per statistical life (VSL), is a major determinant of the benefits of many environmental, health, and safety regulations and other policies. However, selecting an appropriate value is challenging. Different studies yield different results and analysts often find they lack estimates that are directly applicable to the policy they are assessing. Research-synthesis methods are widely used to address these concerns in many fields, yet we find only limited applications to estimating VSL. More structured, criteria-driven review of the available studies is an important first step. Additional meta-analyses that use such review as a starting point are needed to explore variation across studies as well as to adjust estimates to better fit different policy contexts. Carefully designed expert elicitation is significantly underutilized and is particularly important when the available research is limited or inconsistent. Although greater use of such methods is likely to enhance the credibility of the VSL estimates applied in policy analyses, as well as provide greater insights into the advantages and limitations of the available research, it is not clear how much the resulting estimates will vary from those currently used. In the United States, these estimates are generally around $9 million. PMID:25851065

    The importance of 10Be in different applications of accelerator mass spectrometry (AMS) is well-known. In this context the half-life of 10Be has a crucial impact, and an accurate and precise determination of the half-life is a prerequisite for many of the applications of 10Be in cosmic-ray and earth science research. Recently, the value of the 10Be half-life has been the centre of much debate. In order to overcome uncertainties inherent in previous determinations, we introduced a new method of high accuracy and precision. An aliquot of our highly enriched 10Be master solution was serially diluted with increasing well-known masses of 9Be. We then determined the initial 10Be concentration by least square fit to the series of measurements of the resultant 10Be/ 9Be ratio. In order to minimize uncertainties because of mass bias which plague other low-energy mass spectrometric methods, we used for the first time Heavy-Ion Elastic Recoil Detection (HI-ERD) for the determination of the 10Be/ 9Be isotopic ratios, a technique which does not suffer from difficult to control mass fractionation. The specific activity of the master solution was measured by means of accurate liquid scintillation counting (LSC). The resultant combination of the 10Be concentration and activity yields a 10Be half-life of T1/2 = 1.388 ± 0.018 (1 s, 1.30%) Ma. In a parallel but independent study (Chmeleff et al. [11]), found a value of 1.386 ± 0.016 (1.15%) Ma. Our recommended weighted mean and mean standard error for the new value for 10Be half-life based on these two independent measurements is 1.387 ± 0.012 (0.87%) Ma.

    2011-01-01

    Analysis of previous literature on the role of food in life in France and the United States suggests some fundamental differences in attitudes which may generalize outside of the food domain. Questionnaire results from French and American adults suggest that, compared to the French, Americans emphasize quantity rather than quality in making choices, Americans have a higher preference for variety, and Americans usually prefer comforts (things that make life easier) over joys (unique things that make life interesting). The American preference for quantity over quality is discussed in terms of the American focus on abundance as opposed to the French preference for moderation. The American preference for variety is reflective of Americans more personal as opposed to communal food and other values. PMID:21845184

    Objective To elicit health-related quality of life (HRQL) values associated with oral clefting by age using a visual analogue scale, and to explore the appropriateness of using health professionals as evaluators. Methods A representative group of health professionals working on craniofacial and/or cleft palate teams in the United States was sampled. Values (between 0 and 1) representing the HRQL associated with isolated and nonisolated oral clefting for infants, children, adolescents, and adults were obtained. The relationships between selected evaluator characteristics and values were also assessed. Results Of 330 professionals surveyed, 133 (40%) completed and returned reliable evaluations. Overall, HRQL values were clustered toward the right tail of the scale, indicating modest decreases in HRQL. Most evaluators reported feeling confident in completing the evaluations. HRQL values seemed to vary by team type (cleft palate only versus cleft palate/craniofacial care) and geographic location, but no major differences were found overall for any selected evaluator characteristics. Conclusions This study provides HRQL values for oral clefting based on preferences of health professionals that may be useful in evaluating the effectiveness and cost-effectiveness of prevention and treatment strategies, including those carried out in clinical trial studies. The clustered pattern of HRQL values suggests either a consensus among evaluators of a limited burden of oral clefting or an overall lack of understanding of the evaluation task. PMID:16854194

    This study aimed to examine the difficulties with performing valued life activities in relation to pain intensity in women and men with rheumatoid arthritis (RA). In total, 737 persons with RA (73 % women) from three rheumatology units in Sweden responded to a questionnaire measuring performance of 33 valued life activities and self-rated pain. The relationships between performance of valued life activities (VLAs) and pain (measured by visual analogue scale (VAS)) were analysed based on gender. Multiple linear regression analyses were conducted with the total VLA score as dependent variable. Women reported more pain and difficulties in performing valued life activities than men. Across genders, 85 % reported at least one valued life activity affected by RA. Significantly more women than men encountered difficulties in performing some activities such as cooking, gardening and meeting new people. Women reported higher pain intensity (35 mm) than men (31 mm). Almost all 33 difficulty ratings for valued life activities were higher among persons with high pain (>40 mm) than persons with lower pain. Difficulty ratings for valued life activities correlated positively with pain in persons with lower pain, but not among those with high pain. The results highlight the importance of addressing pain, especially among women with RA, as they reported pain to impact on their valued life activities. Interestingly, this was evident also in women with lower levels of pain. PMID:25618175

    Background Due to differences in current socio-economical situation and historically shaped values, different societies have their own concepts of high-quality life. This diversity of concepts interferes with quality of life (Qol) research in health sciences. Before deciding to apply a Qol assessment tool designed in and for another society, a researcher should answer the question: how will this instrument work under the specific circumstances of my research. Our study represents an example of the utilization of qualitative research methods to investigate the appropriateness of the Rheumatoid Arthritis Quality of Life Scale (RAQol) for the assessment of Qol in Estonian patients. Methods Semi-structured interviews were conducted with the rheumatoid arthritis (RA) patients of Tartu University Hospital and these were analyzed using the principles of the grounded theory. Results We described the significance of the questionnaire's items for our patients and also identified topics that were important for the Qol of Estonian RA patients, but that were not assessed by the RAQol. We concluded that the RAQol can be successfully adapted for Estonia; the aspects of Qol not captured by the questionnaire but revealed during our study should be taken into account in future research. Conclusions Our results show that qualitative research can successfully be used for pre-adaptation assessment of a Qol instrument's appropriateness. PMID:15579209

    Work preferences, life values, and personal views of top math/science graduate students (275 men, 255 women) were assessed at ages 25 and 35 years. In Study 1, analyses of work preferences revealed developmental changes and gender differences in priorities: Some gender differences increased over time and increased more among parents than among childless participants, seemingly because the mothers' priorities changed. In Study 2, gender differences in the graduate students' life values and personal views at age 35 were compared with those of profoundly gifted participants (top 1 in 10,000, identified by age 13 and tracked for 20 years: 265 men, 84 women). Again, gender differences were larger among parents. Across both cohorts, men appeared to assume a more agentic, career-focused perspective than women did, placing more importance on creating high-impact products, receiving compensation, taking risks, and gaining recognition as the best in their fields. Women appeared to favor a more communal, holistic perspective, emphasizing community, family, friendships, and less time devoted to career. Gender differences in life priorities, which intensify during parenthood, anticipated differential male-female representation in high-level and time-intensive careers, even among talented men and women with similar profiles of abilities, vocational interests, and educational experiences.

    Background Little is known about longitudinal associations between post-traumatic stress disorder (PTSD) and quality of life (QoL) after exposure to violence. The aims of the current study were to examine quality of life (QoL) and the predictive value of post-traumatic stress disorder (PTSD) for QoL in victims of non-domestic violence over a period of 12 months. Methods A single-group (n = 70) longitudinal design with three repeated measures over a period of 12 months were used. Posttraumatic psychological symptoms were assessed by using the Impact of Event Scale, a 15-item self-rating questionnaire comprising two subscales (intrusion and avoidance) as a screening instrument for PTSD. The questionnaire WHOQOL-Bref was used to assess QoL. The WHOQOL-BREF instrument comprises 26 items, which measure the following broad domains: physical health, psychological health, social relationships, and environment. Results of the analysis were summarized by fitting Structural Equation Modelling (SEM). Results For each category of PTSD (probable cases, risk level cases and no cases), the mean levels of the WHOQOL-Bref subscales (the four domains and the two single items) were stable across time of assessment. Individuals who scored as probable PTSD or as risk level cases had significantly lower scores on the QoL domains such as physical health, psychological health, social relationships and environmental than those without PTSD symptoms. In addition, the two items examining perception of overall quality of life and perception of overall health in WHOQOL showed the same results according to PTSD symptoms such as QoL domains. PTSD symptoms predicted lower QoL at all three assessments. Similarly PTSD symptoms at T1 predicted lower QoL at T2 and PTSD symptoms at T2 predicted lower QoL at T3. Conclusion The presence of PTSD symptoms predicted lower QoL, both from an acute and prolonged perspective, in victims of non-domestic violence. Focusing on the individual's perception of his/her QoL in addition to the illness may increase the treatment priorities and efforts. PMID:17517126

    2013-10-01

    Synthetic biology can be understood as expanding the abilities and aspirations of genetic engineering. Nonetheless, whereas genetic engineering has been subject to criticism due to its endangering biodiversity, synthetic biology may actually appear to prove advantageous for biodiversity. After all, one might claim, synthesizing novel forms of life increases the numbers of species present in nature and thus ought to be ethically recommended. Two perspectives on how to spell out the conception of intrinsic value of biodiversity are examined in order to assess this line of thought. At the cost of introducing two separate capacities of human knowledge acquisition, the 'admiration stance' turns out to reject outright the assumption of a synthetic species' intrinsic value and of an imperative to create novel species. The 'kinship stance' by contrast does ascribe value to both synthetic and natural species and organisms. Nonetheless, while from this perspective creating novel species may become an ethical demand under certain conditions, it favours changing organisms by getting in contact with them rather than synthesizing them. It is concluded that neither the admiration nor the kinship stance warrants a supposed general moral obligation to create novel species to increase biodiversity. PMID:24010852

    Values are desirable, trans-situational goals, varying in importance, that guide behavior. Research has demonstrated that universal values may alter in importance as a result of major life events. The present study examines the effect of spaceflight and the demands of astronauts' job position as life circumstances that affect value priorities. We employed thematic content analysis for references to Schwartz's well-established value markers in narratives (media interviews, journals, and pre-flight interviews) of seven Canadian astronauts and compared the results to the values of National Aeronautics and Space Administration (NASA) and Russian Space Agency (RKA) astronauts. Space flight did alter the level of importance of Canadian astronauts' values. We found a U-shaped pattern for the values of Achievement and Tradition before, during, and after flight, and a linear decrease in the value of Stimulation. The most frequently mentioned values were Achievement, Universalism, Security, and Self-Direction. Achievement and Self Direction are also within the top 4 values of all other astronauts; however, Universalism was significantly higher among the Canadian astronauts. Within the value hierarchy of Canadian astronauts, Security was the third most frequently mentioned value, while it is in seventh place for all other astronauts. Interestingly, the most often mentioned value marker (sub-category) in this category was Patriotism. The findings have important implications in understanding multi-national crew relations during training, flight, and reintegration into society.

    An efficient one-step process to synthesize highly porous (Ca-alginate-SiO2-polycation) shell: (Na-alginate-SiO2) core hybrid beads for cell encapsulation, yielding a reusable long-life photosynthetically active material for a sustainable manufacture of high-value metabolites is presented. Bead formation is based on crosslinking of an alginate biopolymer and mineralisation of silicic acid in combination with a coacervation process between a polycation and the silica sol, forming a semi-permeable external membrane. The excellent mechanical strength and durability of the monodispersed beads and the control of their porosity and textural properties is achieved by tailoring the silica and alginate loading, polycation concentration and incubation time during coacervation. This process has led to the formation of a remarkably robust hybrid material that confers exceptional protection to live cells against sheer stresses and contamination in a diverse range of applications. Dunaliella tertiolecta encapsulated within this hybrid core-shell system display high photosynthetic activity over a long duration (>1 year). This sustainable biotechnology could find use in high value chemical harvests and biofuel cells to photosynthetic solar cells (energy transformation, electricity production, water splitting technologies). Furthermore the material can be engineered into various forms from spheres to variable thickness films, broadening its potential applications. PMID:25721859

    Terrestrial land and its resources are finite, though, for economic and socio-cultural needs of humans, these natural resources are further exploited. It highlights the need to quantify the impact humans possibly have on the environment due to occupation and transformation of land. As a starting point of this paper (1(st) objective), the land use activities, which may be mainly socio-culturally or economically oriented, are identified in addition to the natural land-based processes and stocks and funds that can be altered due to land use. To quantify the possible impact anthropogenic land use can have on the natural environment, linked to a certain product or service, life cycle assessment (LCA) is a tool commonly used. During the last decades, many indicators are developed within the LCA framework in an attempt to evaluate certain environmental impacts of land use. A second objective of this study is to briefly review these indicators and to categorize them according to whether they assess a change in the asset of natural resources for production and consumption or a disturbance of certain ecosystem processes, i.e. ecosystem health. Based on these findings, two enhanced proxy indicators are proposed (3(rd) objective). Both indicators use net primary production (NPP) loss (potential NPP in the absence of humans minus remaining NPP after land use) as a relevant proxy to primarily assess the impact of land use on ecosystem health. As there are two approaches to account for the natural and productive value of the NPP remaining after land use, namely the Human Appropriation of NPP (HANPP) and hemeroby (or naturalness) concepts, two indicators are introduced and the advantages and limitations compared to state-of-the-art NPP-based land use indicators are discussed. Exergy-based spatially differentiated characterization factors (CFs) are calculated for several types of land use (e.g., pasture land, urban land). PMID:26808405

    The present study compares phase-dependent measures of local dynamic stability of daily life walking with 35 conventional gait features in their ability to discriminate between community-dwelling older fallers and nonfallers. The study reanalyzes 3D-acceleration data of 3-day daily life activity from 39 older people who reported less than 2 falls during one year and 31 who reported two or more falls. Phase-dependent local dynamic stability was defined for initial perturbation at 0%, 20%, 40%, 60%, and 80% of the step cycle. A partial least square discriminant analysis (PLS-DA) was used to compare the discriminant abilities of phase-dependent local dynamic stability with the discriminant abilities of 35 conventional gait features. The phase-dependent local dynamic stability λ at 0% and 60% of the step cycle discriminated well between fallers and nonfallers (AUC = 0.83) and was significantly larger (p < 0.01) for the nonfallers. Furthermore, phase-dependent λ discriminated as well between fallers and nonfallers as all other gait features combined. The present result suggests that phase-dependent measures of local dynamic stability of daily life walking might be of importance for further development in early fall risk screening tools.

    We model a value of statistical life (VSL) transfer function for application to road-safety engineering in developing countries through an income-disaggregated meta-analysis of scope-sensitive stated preference VSL data. The income-disaggregated meta-analysis treats developing country and high-income country data separately. Previous transfer functions are based on aggregated datasets that are composed largely of data from high-income countries. Recent evidence, particularly with respect to the income elasticity of VSL, suggests that the aggregate approach is deficient because it does not account for a possible change in income elasticity across income levels. Our dataset (a minor update of the OECD database published in 2012) includes 123 scope-sensitive VSL estimates from developing countries and 185 scope-sensitive estimates from high-income countries. The transfer function for developing countries gives VSL=1.3732E-4×(GDP per capita)(∧)2.478, with VSL and GDP per capita expressed in 2005 international dollars (an international dollar being a notional currency with the same purchasing power as the U.S. dollar). The function can be applied for low- and middle-income countries with GDPs per capita above $1268 (with a data gap for very low-income countries), whereas it is not useful above a GDP per capita of about $20,000. The corresponding function built using high-income country data is VSL=8.2474E+3×(GDP per capita)(∧).6932; it is valid for high-income countries but over-estimates VSL for low- and middle-income countries. The research finds two principal significant differences between the transfer functions modeled using developing-country and high-income-country data, supporting the disaggregated approach. The first of these differences relates to between-country VSL income elasticity, which is 2.478 for the developing country function and .693 for the high-income function; the difference is significant at p<0.001. This difference was recently postulated but not analyzed by other researchers. The second difference is that the traffic-risk context affects VSL negatively in developing countries and positively in high-income countries. The research quantifies uncertainty in the transfer function using parameters of the non-absolute distribution of relative transfer errors. The low- and middle-income function is unbiased, with a median relative transfer error of -.05 (95% CI: -.15 to .03), a 25th percentile error of -.22 (95% CI: -.29 to -.19), and a 75th percentile error of .20 (95% CI: .14 to .30). The quantified uncertainty characteristics support evidence-based approaches to sensitivity analysis and probabilistic risk analysis of economic performance measures for road-safety investments.

    The equilibrium concentration ratio is typically the parameter used to estimate organism activity concentrations within wildlife dose assessment tools. Whilst this is assumed to be fit for purpose, there are scenarios such as accidental or irregular, fluctuating, releases from licensed facilities when this might not be the case. In such circumstances, the concentration ratio approach may under- or over-estimate radiation exposure depending upon the time since the release. To carrying out assessments for such releases, a dynamic approach is needed. The simplest and most practical option is representing the uptake and turnover processes by first-order kinetics, for which organism- and element-specific biological half-life data are required. In this paper we describe the development of a freely available international database of radionuclide biological half-life values. The database includes 1907 entries for terrestrial, freshwater, riparian and marine organisms. Biological half-life values are reported for 52 elements across a range of wildlife groups (marine=9, freshwater=10, terrestrial=7 and riparian=3 groups). Potential applications and limitations of the database are discussed. PMID:26378959

    In 1825, the actuary Benjamin Gompertz read a paper, ‘On the nature of the function expressive of the law of human mortality, and on a new mode of determining the value of life contingencies’, to the Royal Society in which he showed that over much of the adult human lifespan, age-specific mortality rates increased in an exponential manner. Gompertz's work played an important role in shaping the emerging statistical science that underpins the pricing of life insurance and annuities. Latterly, as the subject of ageing itself became the focus of scientific study, the Gompertz model provided a powerful stimulus to examine the patterns of death across the life course not only in humans but also in a wide range of other organisms. The idea that the Gompertz model might constitute a fundamental ‘law of mortality’ has given way to the recognition that other patterns exist, not only across the species range but also in advanced old age. Nevertheless, Gompertz's way of representing the function expressive of the pattern of much of adult mortality retains considerable relevance for studying the factors that influence the intrinsic biology of ageing. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society. PMID:25750242

    The effect of individual engine component life distributions on engine life prediction was determined. A Weibull-based life and reliability analysis of the NASA Energy Efficient Engine was conducted. The engine s life at a 95 and 99.9 percent probability of survival was determined based upon the engine manufacturer s original life calculations and assumed values of each of the component s cumulative life distributions as represented by a Weibull slope. The lives of the high-pressure turbine (HPT) disks and blades were also evaluated individually and as a system in a similar manner. Knowing the statistical cumulative distribution of each engine component with reasonable engineering certainty is a condition precedent to predicting the life and reliability of an entire engine. The life of a system at a given reliability will be less than the lowest-lived component in the system at the same reliability (probability of survival). Where Weibull slopes of all the engine components are equal, the Weibull slope had a minimal effect on engine L(sub 0.1) life prediction. However, at a probability of survival of 95 percent (L(sub 5) life), life decreased with increasing Weibull slope.

  9. Diminishing willingness to pay per quality-adjusted life year: valuing acute foodborne illness.

    2011-09-01

    We design and conduct a stated-preference survey to estimate willingness to pay (WTP) to reduce foodborne risk of acute illness and to test whether WTP is proportional to the corresponding gain in expected quality-adjusted life years (QALYs). If QALYs measure utility for health, then economic theory requires WTP to be nearly proportional to changes in both health quality and duration of illness and WTP could be estimated by multiplying the expected change in QALYs by an appropriate monetary value. WTP is elicited using double-bounded, dichotomous-choice questions in which respondents (randomly selected from the U.S. general adult population,?n?= 2,858) decide whether to purchase a more expensive food to reduce the risk of foodborne illness. Health risks vary by baseline probability of illness, reduction in probability, duration and severity of illness, and conditional probability of mortality. The expected gain in QALYs is calculated using respondent-assessed decrements in health-related quality of life if ill combined with the duration of illness and reduction in probability specified in the survey. We find sharply diminishing marginal WTP for severity and duration of illness prevented. Our results suggest that individuals do not have a constant rate of WTP per QALY, which implies that WTP cannot be accurately estimated by multiplying the change in QALYs by an appropriate monetary value.

    Anecdote is defined as "a usually short narrative of an interesting, amusing, or biographical incident" and are not often deemed scientifically valuable (www.merriam-webster.com). Anecdotes can be analyzed, however, and those observations can become the initiation of important and groundbreaking work. In this article, we describe aecdotes of several cases which by themselves had seemingly little value. The value was added later, when these concepts were extrapolated to important projects, which expanded into series of experiences, which were reproducible and able to be analyzed and judged as valuable devices and/or methods. The authors recognize that some of the images are old and not of great quality but the information provided is as complete as possible and reliable. PMID:24468424

    Over the past 10 years, it has become unpopular to talk about definitions of life, under the assumption that attempts at a precise definition are counterproductive. Recent attempts have failed to meet strict philosophical criteria for definitions and have failed to reach consensus. I argue that provisional definitions are necessary for clear communications. Our current knowledge of biology justifies a number of universal claims about the category of life. Whether or not "life" represents a natural category, it maps to a number of important, observable processes. Given the importance of those processes and the extent of our knowledge, plural explicit definitions of life (and related categories) will be necessary for progress in astrobiology and origin-of-life studies as well as biology in general. I propose concrete categories related to, but not necessarily coextensive with, life for clear communication and hypothesis formation: Woese life, Darwin life, Haldane life. PMID:25415254

    There is some indication that life may have originated readily under primitive earth conditions. If there were multiple origins of life, the result could have been a polyphyletic biota today. Using simple stochastic models for diversification and extinction, we conclude: (1) the probability of survival of life is low unless there are multiple origins, and (2) given survival of life and given as many as 10 independent origins of life, the odds are that all but one would have gone extinct, yielding the monophyletic biota we have now. The fact of the survival of our particular form of life does not imply that it was unique or superior.

    In the 21st century, psychophysiology will face the challenge of establishing ethical principles and practical means for the genetic and social influencing of the development of human beings. Neuronal imprinting of beliefs and morality within infantile minds will be necessary for the peaceful coexistence of races and cultures. This process requires study and consideration, among others, of the following psychophysiological facts: (1) Genes do not transmit moral values. (2) Material support of physiological activities is necessary for the existence and development of mental functions. (3) Imprinting of human values is based on material changes within neuronal structures. (4) Early neuronal imprinting is performed without personal awareness or consent of the individual and depends on sensory inputs, mainly from the social structure of the group. (5) Biological structures lack values. Personal and social antagonisms do not depend on genes, but on cultural indoctrination. (6) Pleasure and punishment (positive and negative reinforcement) are the two main elements, which regulate animal and human behavior. (7) Values must be chosen by adults, who decide the questions 'why'? 'when'? 'which ones'?, 'who should teach'?, 'what?' and 'how'? (8) Many biological imperatives are shared by all animals and by all people. Human beings may be considered the 'crickets of the Universe', unable to understand the mysteries of nature because of our insufficient neuronal capacity. (9) Our emotional life is mainly related to the structure of the limbic system controlled by the neocortex. (10) New theories based on the integration of physics, chemistry, biology and other specific areas of knowledge, as proposed by the General Theory of Systems, will avoid 'opposites', favoring the acceptance of complementary aspects of reality. (11) Early education will promote preferential learning which depends on both genetic endowment and neuronal development influenced by experience. It is the responsibility of psychophysiology to establish the guidelines for better education, clarifying the material and psychological aspects of the mind. PMID:10677650

    2015-12-01

    Bioelectrical impedance analysis (BIA) and especially its derived parameter phase angle have been widely used in different populations. The variability of BIA measures has often been cited as a major limitation for its clinical use in evaluating nutritional status and overall health of patients. Cancer patients often present with malnourishment and cachexia, which complicate the course of treatment and affect outcomes. PubMed, CINAHL, EBSCO and Cochrane Library have been searched for relevant publications in English for BIA in cancer patients. Out of 197 total results, 27 original research articles related to BIA measures in cancer patients were included in this review. Studies indicate that the use of BIA and phase angle measures can benefit in the clinical management of cancer patients in multiple ways: in the prevention; diagnosis; prognosis; and outcomes related to treatments that affect nutritional and overall health status. Phase angle and fat-free mass measures were most commonly evaluated and correlated with nutritional status and survival rate. One limitation of BIA measures is the high interpatient variability which requires careful interpretation of results in the context of the individual patient rather than comparison with population data. The BIA and phase angle provide practitioners for the evaluation of nutritional and overall health status in cancer patients with a convenient and non-invasive technique and should be encouraged.

    1973-03-01

    Foods must furnish (i) calories, which can readily be measured, and (ii) raw materials necessary for the building and maintenance of metabolic machinery which makes possible fuel utilization. We have called this "beyond-calorie" quality of food its "trophic" value. This concept has more unity than appears on the surface, and is capable of approximate measurement by biological testing as our experiments show. The trophic value of a food cannot be ascertained from food composition tables because only a smattering of the necessary information is commonly furnished. A food cannot support life if it is missing, or deficient with respect to, any one of the necessary nutrients. A tabulation which includes only a few nutrients-e.g., calcium, thiamin, riboflavin, niacin, phosphorus, and iron-can be woefully misleading, especially if these individual nutrients have been added by way of fortification. THE MEASUREMENT WE HAVE APPLIED TO A NUMBER OF FOODS IS POTENTIALLY VALUABLE FOR COMPARING SIMILAR FOOD PRODUCTS: two grains, two breads, two milk products, or for comparison of the same food grown, processed, or preserved in different ways. By using essentially this method we have found that barnyard eggs are somewhat superior to battery eggs, but that whether they are fertile or infertile makes no difference. We are of the opinion that extensive biological testing of many commercial food products is highly desirable to help promote human health and better internal environments for our cells and tissues.

    The economic value of restoring Deckers Creek in Monongalia and Preston counties of West Virginia was determined from mail, Internet, and personal contact surveys. Multiattribute, choice experiments were conducted and nested logit models were estimated to derive the economic values of full restoration for three attributes of this creek: aquatic life, swimming, and scenic quality. Their relative economic values were that aquatic life > scenic quality ≈ swimming. These economic values imply that respondents had the highest value for aquatic life when fully restoring Deckers Creek to a sustainable fishery rather than a "put and take" fishery that cannot sustain fish populations. The welfare improvement estimates for full restoration of all three attributes ranged between 12 and 16 per month per household. Potential stream users (anglers) had the largest welfare gain from restoration, while nonangler respondents had the lowest. When these estimates were aggregated up to the entire watershed population, the benefit from restoration of Deckers Creek was estimated to be about $1.9 million annually. This benefit does not account for any economic values from partial stream restoration. On the basis of log likelihood tests of the nested logit models, two subsamples of the survey population (the general population and stream users) were found to be from the same population. Thus restoration choices by stream users may be representative of the watershed population, although the sample size of stream users was small in this research.

    The evolution of life has been a big enigma despite rapid advancements in the field of astrobiology, microbiology and genetics in recent years. The answer to this puzzle is as mindboggling as the riddle relating to evolution of the universe itself. Despite the fact that panspermia has gained considerable support as a viable explanation for origin of life on the earth and elsewhere in the universe, the issue, however, remains far from a tangible solution. This paper examines the various prevailing hypotheses regarding origin of life-like abiogenesis, RNA world, iron-sulphur world and panspermia, and concludes that delivery of life-bearing organic molecules by the comets in the early epoch of the earth alone possibly was not responsible for kick-starting the process of evolution of life on our planet.

    Tarrant, Mihael A; Cordell, H Ken

    2002-11-01

    Public values toward forests have changed since the late 1980s, from a commodity-oriented perspective toward a more inclusive (commodity and non-commodity) orientation. This study examines the influence of four indicators of population diversity (age, ethnic background, place of residence, and gender) on amenity values of forests, environmental attitudes, and forest value-attitude correspondence. Four values of public and private forests were assessed, wood production (utilitarian value), clean air (a life support value), scenic beauty (an aesthetic value), and heritage (a spiritual value). Environmental attitudes were measured using a modified version of the New Environmental Paradigm scale. Five hundred and forty-eight randomly selected residents of households in 13 states of the Southern United States participated in a telephone interview. Age and ethnic background were found to moderate the value-attitude relationship, with the strength of the association being dependent upon the type of forest (i.e., public or private) and the forest value (i.e., utilitarian, life support, spiritual, and aesthetic). Females, younger persons (less than 43 years old), and whites reported lower utilitarian values of forests than their respective counterparts. Results are interpreted within the context of an emerging post-material society, in which a biocentric orientation to forests and the natural environment may be favored more by a younger (versus older) generation and increasingly racially diverse U.S. population. Implications for managing forests using a multiple-values (versus multiple-uses) approach are discussed. PMID:12375089

    Objective To identify the prevalence of disability in a wide range of valued life activities (VLAs) among individuals with systemic lupus erythematosus (SLE), 1-year changes in such disability, and predictors of and changes in VLA disability. Methods Data were from 2 waves of a cohort of 829 individuals with SLE interviewed annually by telephone. VLA disability was assessed using a scale rating the difficulty of performing 21 activities. Scores were also calculated for subscales corresponding to obligatory, committed, and discretionary activities. Changes in VLA disability from baseline to 1-year followup were assessed. Sociodemographic and disease status measures were examined as predictors of and changes in VLA disability using multiple regression analyses. Results Almost half of the subjects were unable to perform ?1 VLA at baseline. Almost all (91%) reported ?1 VLA affected by SLE. One-quarter of the subjects experienced a significant increase in the number of activities they were unable to perform; approximately half experienced significant increases in the number of activities affected and in difficulty scores. Proportions of individuals whose disability increased and whose disability decreased were roughly equivalent. Disease status measures accounted for 6272% of the variation in VLA difficulty. More severe disease status was predictive of increases in VLA difficulty; few predictors of improvements were identified. Conclusion VLA disability was common, with more disability noted in committed and discretionary activities than in obligatory activities. Because VLA disability has been linked to psychological well-being in previous studies, identification of factors that may protect against such disability is important. PMID:18383406

  8. How to Assess the Value of Medicines?

    PubMed Central

    Simoens, Steven

    2010-01-01

    This study aims to discuss approaches to assessing the value of medicines. Economic evaluation assesses value by means of the incremental cost-effectiveness ratio (ICER). Health is maximized by selecting medicines with increasing ICERs until the budget is exhausted. The budget size determines the value of the threshold ICER and vice versa. Alternatively, the threshold value can be inferred from pricing/reimbursement decisions, although such values vary between countries. Threshold values derived from the value-of-life literature depend on the technique used. The World Health Organization has proposed a threshold value tied to the national GDP. As decision makers may wish to consider multiple criteria, variable threshold values and weighted ICERs have been suggested. Other approaches (i.e., replacement approach, program budgeting and marginal analysis) have focused on improving resource allocation, rather than maximizing health subject to a budget constraint. Alternatively, the generalized optimization framework and multi-criteria decision analysis make it possible to consider other criteria in addition to value. PMID:21607066

    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.

    2009-01-01

    Background Subclinical disability, the need for modifications in task performance or frequency without reporting difficulty in the task, has been identified as a stage along the disability continuum. We estimate the prevalence of subclinical disability in valued life activities (VLAs) among individuals with rheumatoid arthritis (RA), identify characteristics of individuals with VLA subclinical disability, and estimate the ability of VLA subclinical disability to predict later decrements in functioning. Methods Data were from three years of a longitudinal panel study of individuals with RA, for which annual structured telephone interviews are conducted (n=508 in year 1, 442 in year 3). Respondents rated difficulty in VLAs and then reported whether they used any of four behavioral modifications (limitations, extra time, help, equipment) for each. Subclinical disability was defined for each VLA as no reported difficulty with use of any modification. Multiple regression analyses identified predictors of subclinical disability in year 1, and the role of year 1 subclinical disability in development of overt disability between year 1 and year 3. Results Almost three quarters exhibited subclinical disability in at least one VLA in year 1. Duration of RA was consistently associated with subclinical disbility. Individuals with subclinical disability at baseline were significantly more likely to experience increases in functional limitations (OR=1.09 [1.01,1.18]) and VLA disability (Total VLA: OR=1.14 [1.06,1.23]) over a prospective two-year period. Conclusion Subclinical disability may be a valuable marker of individuals in a disability transition phase who are particularly susceptible to intervention to enable them to maintain functioning.

Part II of the value of imaging series reviews current initiatives that demonstrate value beyond the image interpretation. Standardizing processes, reducing the radiation dose of our examinations, clarifying written reports, improving communications with patients and providers, and promoting appropriate imaging through decision support are all ways we can provide safer, more consistent, and higher quality care. As payers and policy makers push to drive value, research that demonstrates the value of these endeavors, or lack thereof, will become increasingly sought after and supported. PMID:26683509

    Doctinary overlays on the definition of life can effectively be avoided by focusing discussion on microorganisms, their vital processes, and their genetic pedigree. To reach beyond these present and highly advanced forms of life and to inquire about its origin it is necessary to consider the requirements imposed by the environment. These requirements include geophysically and geochemically acceptable conjectures for the generation of source compounds, their concentration from dilute solution, and their selective combination into functional biomolecules. For vital function these macromolecules require programming in the form of specific sequence motifs. This critical programming constitutes the scientifically least understood process in the origin of life. Once this stage has been surpassed the laws of Darwinian evolution can operate in ways that are understood and experimentally demonstrated.

    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.

    I used thematic narrative analysis, informed by the developmental life course perspective, to formulate a line of semistructured questioning for interviews with 6 older adults who experienced ongoing symptoms of schizophrenia. From the 31 resulting interviews and 38 observation points, I developed life history narratives that yielded findings across four shared core themes. In this article I present my findings on the theme of narrative insight into schizophrenia in later years. Whereas only 2 of the participants had clinical insight into their mental illness, all had developed personal stories about their lives with schizophrenia. I discuss the significance of the shared narrative profile and the importance of using narrative insight to develop more effective clinical practices and to focus future research with older adults with schizophrenia.

  1. The relative value of growth.

    PubMed

    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. PMID:15807043

    Spending on drugs has become a target for cost-containment measures because of its continual growth, both in absolute terms and as a proportion of overall healthcare expenditures. However, considering drug spending in isolation from other healthcare components neglects the benefit of drugs to Canada's healthcare system, society and economy. Drugs, when used appropriately as part of overall disease management, have increased life expectancy and quality of life, have avoided more costly alternatives such as hospitalisation and surgery, and have decreased worker absenteeism and increased their productivity. Current evidence suggests that drugs represent good value for money and are an integral part of a cost-effective and sustainable healthcare system. Cost-containment measures should focus on appropriate use of medications and improving adherence to therapeutic regimens for optimal patient outcomes. PMID:16055940

  4. Methods of valuing environmental externalities

    1991-03-01

    Estimating a monetary value for environmental externalities provides an approximation of the societal value of reducing impacts on human health and the environment from electrical energy supply. This method can be used for comparison of resources, including utility and nonutility generation, demand-side management and off-system power purchases. A dollar estimate of the full societal cost of the supply option is established by placing a value on its air, water and terrestrial effects and adding these costs to the option's capital, operating and maintenance costs. This article provides a rationale for monetizing externalities and addresses the strengths and weaknesses of four techniques for monetizing, with examples of the application of each method. The authors preferred technique for incorporating externalities into utility planning in the near term - implied valuation through the estimation of the marginal cost of abatement - is discussed in detail. 2 tabs.

  5. The Value of Certainty (Invited)

    2009-12-01

    It is clear that Earth science data are valued, in part, for their ability to provide some certainty about the past state of the Earth and about its probable future states. We can sharpen this notion by using seven categories of value ● Warning Service, requiring latency of three hours or less, as well as uninterrupted service ● Information Service, requiring latency less than about two weeks, as well as unterrupted service ● Process Information, requiring ability to distinguish between alternative processes ● Short-term Statistics, requiring ability to construct a reliable record of the statistics of a parameter for an interval of five years or less, e.g. crop insurance ● Mid-term Statistics, requiring ability to construct a reliable record of the statistics of a parameter for an interval of twenty-five years or less, e.g. power plant siting ● Long-term Statistics, requiring ability to construct a reliable record of the statistics of a parameter for an interval of a century or less, e.g. one hundred year flood planning ● Doomsday Statistics, requiring ability to construct a reliable statistical record that is useful for reducing the impact of `doomsday' scenarios While the first two of these categories place high value on having an uninterrupted flow of information, and the third places value on contributing to our understanding of physical processes, it is notable that the last four may be placed on a common footing by considering the ability of observations to reduce uncertainty. Quantitatively, we can often identify metrics for parameters of interest that are fairly simple. For example, ● Detection of change in the average value of a single parameter, such as global temperature ● Detection of a trend, whether linear or nonlinear, such as the trend in cloud forcing known as cloud feedback ● Detection of a change in extreme value statistics, such as flood frequency or drought severity For such quantities, we can quantify uncertainty in terms of the entropy which is calculated by creating a set of discrete bins for the value and then using error estimates to assign probabilities, pi, to each bin. The entropy, H, is simply H = ∑i pi log2(1/pi) The value of a new set of observations is the information gain, I, which is I = Hprior - Hposterior The probability distributions that appear in this calculation depend on rigorous evaluation of errors in the observations. While direct estimates of the monetary value of data that could be used in budget prioritizations may not capture the value of data to the scientific community, it appears that the information gain may be a useful start in providing a `common currency' for evaluating projects that serve very different communities. In addition, from the standpoint of governmental accounting, it appears reasonable to assume that much of the expense for scientific data become sunk costs shortly after operations begin and that the real, long-term value is created by the effort scientists expend in creating the software that interprets the data and in the effort expended in calibration and validation. These efforts are the ones that directly contribute to the information gain that provides the value of these data.

    The phrase 'quality of life' is actually misleading. The designation suggests that the issue has to do with 1 quality, whereas in fact more qualities of life are indicated. Four of these qualities are: 1. the 'livability' of the surroundings, 2. the 'life-abilities' of the individual, 3. the 'utility of life' and 4. the subjective 'satisfaction' with a person's own life. The various qualities cannot meaningfully be collected together in an index. The most comprehensive measure of quality of life is how long and happily a person lives. The relationship between that and oral health has still hardly been studied. PMID:21491762

    2010-04-01

    We make an estimate of the likelihood function for the Higgs vacuum expectation value (vev) by imposing anthropic constraints on the existence of atoms while allowing the other parameters of the standard model to also be variable. We argue that the most important extra ingredients are the Yukawa couplings, and for the intrinsic distribution of Yukawa couplings we use the scale-invariant distribution which is favored phenomenologically. The result is successful phenomenologically, favoring values close to the observed vev. We also discuss modifications that can change these conclusions. Our work supports the hypothesis that the anthropic constraints could be the origin of the small Higgs vev.

  9. LATENT LIFE OF ARTERIES.

    Carrel, A

    1910-07-23

    When a segment of artery, killed by heat, formalin or glycerin is transplanted, it undergoes a rapid degeneration. Its muscle fibers disappear while the tissue of the host reacts by building a new wall of connective tissue. When the transplanted vessel has been preserved in a condition of latent life, no degeneration of the wall occurs, or the wall undergoes only partial degeneration. The muscle fibers can keep their normal appearance, even for a long time after the operation. It is, therefore, demonstrated that arteries can be preserved outside of the body in a condition of unmanifested actual life. The best method of preservation consists of placing the vessels, immersed in vaselin, in an ice box, the temperature of which is slightly above the freezing point. From a surgical standpoint, the transplantation of preserved vessels can be used with some safety. When the arteries were kept in defibrinated blood or vaselin and in cold storage, the proportion of positive results was 75 and 80 per cent., and this can probably be increased. PMID:19867337

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

    PubMed

    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.

    NASA Technical Reports Server (NTRS)

    2005-01-01

    The successful development of advanced aerospace engines depends greatly on the capabilities of high performance materials and structures. Advanced materials, such as nickel based single crystal alloys, metal foam, advanced copper alloys, and ceramics matrix composites, have been engineered to provide higher engine temperature and stress capabilities. Thermal barrier coatings have been developed to improve component durability and fuel efficiency, by reducing the substrate hot wall metal temperature and protecting against oxidation and blanching. However, these coatings are prone to oxidation and delamination failures. In order to implement the use of these materials in advanced engines, it is necessary to understand and model the evolution of damage of the metal substrate as well as the coating under actual engine conditions. The models and the understanding of material behavior are utilized in the development of a life prediction methodology for hot section components. The research activities were focused on determining the stress and strain fields in an engine environment under combined thermo-mechanical loads to develop life prediction methodologies consistent with the observed damage formation of the coating and the substrates.

    Radioactive decay half-life measurements of (223)Ra, a member of the (235)U naturally occurring radioactive decay series, have been performed of a radiochemically pure solution with an ionisation chamber. The radioactive decay of (223)Ra was followed for 50 days, approximately 4.4 half-lives. The deduced half-life of (223)Ra was found to be 11.4358 (28) days, supporting the other published direct measurements. A detailed uncertainty budget is presented. A new evaluation of the published half-life values was performed, indicating significant variation across the existing published values, suggesting that further measurements of the half-life of (223)Ra are required. A new evaluated half-life has been calculated using a power moderated weighted mean of selected experimental values, with a new value of the recommended half-life for (223)Ra of 11.4354 (17) days.

A grid was used to analyse the criteria on which decisions were based, and the results were enriched by an analysis of interviews with the doctors in at these centres (31 interviews with doctors from the 18 centres). The goal was to describe in detail and to specify the criteria on which decisions to withhold or withdraw LST were based, extracted from the files. The second paper deals exclusively with the interviews with doctors and analyses their lifetimes experience and perception Methods We carried out semi-directed interviews with nephrologists from all the paediatric nephrology centres in France and the French-speaking regions of Switzerland and Belgium. Results We interviewed 46 paediatric nephrologists. Most were aware that decisions relating to LST are necessary and based on the assessment of the childs quality of life. According to them, decisions are not based on scientific criteria, but on the capacity to accept handicap, the familys past experiences and the doctors own projections. They report that their task is particularly difficult when their action may contribute to death (withdrawal of treatment, acceleration of the process). They feel that their duty is to help the families in the acceptation of the doctors decision rather than to encourage their participation in the decision-making process. Conclusions This paper shows that paediatric nephrologists differ in their opinions, mostly due to their own ethical convictions. This observation highlights the need to establish common rules taking into account the views held by doctors. This is the only way to establish an ethical code shared by professionals. PMID:16204280

    In this work, the half life of the ? decay of 52V was measured by following the activity of 32 samples of 50 ?g each after they were irradiated in the IEA-R1 reactor of IPEN-CNEN/SP. The results were then fitted using a non-paralizable dead time correction to the regular exponential decay and the individual half-life values obtained were then analyzed using different statistical methods (Weighted Average, Normalized Residuals and Rajeval Technique), resulting in a value of 3.733(4) min. The obtained result is somewhat smaller than tabulated one but the difference does not surpass two standard deviations.

  4. Second Life for Electric Vehicle Batteries: Answering Questions on Battery Degradation and Value

    Battery second use – putting used plug-in electric vehicle (PEV) batteries into secondary service following their automotive tenure – has been proposed as a means to decrease the cost of PEVs while providing low cost energy storage to other fields (e.g. electric utility markets). To understand the value of used automotive batteries, however, we must first answer several key questions related to National Renewable Energy Laboratory (NREL) has developed a methodology and the requisite tools to answer these questions, including NREL’s Battery Lifetime Simulation Tool (BLAST). Herein we introduce these methods and tools, and demonstrate their application. We have found that capacity fade from automotive use has a much larger impact on second use value than resistance growth. Where capacity loss is driven by calendar effects more than cycling effects, average battery temperature during automotive service – which is often driven by climate – is found to be the single factor with the largest effect on remaining value. Installing hardware and software capabilities onboard the vehicle that can both infer remaining battery capacity from in-situ measurements, as well as track average battery temperature over time, will thereby facilitate the second use of automotive batteries.

It must have been around three o'clock in the morning of a rather cold winter night in the late 1980s, when he connected his Atari 1040ST computer to a synthesizer to test the first prototype of a system, which he was developing for his thesis. The system, named CAMUS (short for Cellular Automata Music), implemented a method that he invented to render music from the behaviour of the Game of Life (GoL) cellular automata (CA).

    Describing lessons learned from Value Engineers (VE) studies at a government-funded research laboratory reveals how project managers were encouraged to use VE and how their projects benefited from the VE savings. The five major lessons were: An officer of ''free'' VE is a low-risk incentive to encourage the use of VE; More costs savings can be identified by VE studies than cost reviews or design reviews; Large projects can benefit from repeat VE studies; VE teams can identify surprising savings when allowed to challenge all design criteria; VE programs can be costs effective even though return on investment may vary among projects. 6 tabs.

    The half-life of ^44Ti, which is of interest in cosmology, has been measured by several groups of scientests over the past 30 years. These measurements give conflicting values which range from 49 to 66 years. For this reason a measurement of the ^44Ti half-life was undertaken at Argonne. The decay of mixed sources of ^44Ti and ^60Co has been followed at three institutions- Argonne, Jerusalem and Torino. Half-life values have been determined from the decay of ^44Ti gamma rays alone and also from the decay ^44Ti gamma rays relative to ^60Co whose life-time is very precisely known (5.2714 0.0005 y). The gamma ray spectra of the samples were measured with Ge detectors at regular intervals for 5 years. The measurements are complete and the analysis is underway. The details of the measurements and the half-life values obtained from these measurements will be presented.

    Background: In utero exposure of the fetus to a stressor can lead to disease in later life. Epigenetic mechanisms are likely mediators of later-life expression of early-life events. Objectives: We examined the current state of understanding of later-life diseases resulting from early-life exposures in order to identify in utero and postnatal indicators of later-life diseases, develop an agenda for future research, and consider the risk assessment implications of this emerging knowledge. Methods: This review was developed based on our participation in a National Research Council workshop titled “Use of in Utero and Postnatal Indicators to Predict Health Outcomes Later in Life: State of the Science and Research Recommendations.” We used a case study approach to highlight the later-life consequences of early-life malnutrition and arsenic exposure. Discussion: The environmental sensitivity of the epigenome is viewed as an adaptive mechanism by which the developing organism adjusts its metabolic and homeostatic systems to suit the anticipated extrauterine environment. Inappropriate adaptation may produce a mismatch resulting in subsequent increased susceptibility to disease. A nutritional mismatch between the prenatal and postnatal environments, or early-life obesogen exposure, may explain at least some of the recent rapid increases in the rates of obesity, type 2 diabetes, and cardiovascular diseases. Early-life arsenic exposure is also associated with later-life diseases, including cardiovascular disease and cancer. Conclusions: With mounting evidence connecting early-life exposures and later-life disease, new strategies are needed to incorporate this emerging knowledge into health protective practices.

    Classical mechanics is based upon a mechanical picture of nature that is fundamentally incorrect. It has been replaced at the basic level by a radically different theory: quantum mechanics. This change entails an enormous shift in one`s basic conception of nature, one that can profoundly alter the scientific image of man himself. Self-image is the foundation of values, and the replacement of the mechanistic self-image derived from classical mechanics by one concordant with quantum mechanics may provide the foundation of a moral order better suited to today`s times, a self-image that endows human life with meaning, responsibility, and a deeper linkage to nature as a whole.

  12. The Value of Clean Air

    NASA Astrophysics Data System (ADS)

    Shindell, D. T.

    2014-12-01

    How can society place a value on clean air? I present a multi-impact economic valuation framework called the Social Cost of Atmospheric Release (SCAR) that extends the Social Cost of Carbon (SCC) used previously for carbon dioxide (CO2) to a broader range of pollutants and impacts. Values consistently incorporate health impacts of air quality along with climate damages. The latter include damages associated with aerosol-induced hydrologic cycle changes that lead to net climate benefits when reducing cooling aerosols. Evaluating a 1% reduction in current global emissions, benefits with a high discount rate are greatest for reductions of co-emitted products of incomplete combustion (PIC), followed by sulfur dioxide (SO2), nitrogen oxides (NOx) and then CO2, ammonia and methane. With a low discount rate, benefits are greatest for CO2 reductions, though the sum of SO2, PIC and methane is substantially larger. These results suggest that efforts to mitigate atmosphere-related environmental damages should target a broad set of emissions including CO2, methane and aerosol/ozone precursors. Illustrative calculations indicate environmental damages are 410-1100 billion yr-1 for current US electricity generation ( 19-46 per kWh for coal, 4-24 for gas) and 3.80 (-1.80/+2.10) per gallon of gasoline ($4.80 (-3.10/+3.50) per gallon for diesel). These results suggest that total atmosphere-related environmental damages plus generation costs are much greater for coal-fired power than other types of electricity generation, and that damages associated with gasoline vehicles substantially exceed those for electric vehicles.

    Background Quality of life (QoL) for patients with inflammatory skin disease can be significant, but has been evaluated in just one study in dermatomyositis (DM). Objective To examine the relationship between the Cutaneous Disease and Activity Severity Index (CDASI), a DM-specific cutaneous severity instrument, and various QoL study instruments and to determine the impact of DM on QoL. Methods Skin-specific QoL instruments, the Skindex and the Dermatology Life Quality Index (DLQI), and global medical QoL instruments, the SF-36 and the HAQ-DI, were used. Pruritus was evaluated by a visual analogue scale (VAS) and a 010 scale in DM and CLE populations, respectively. Results There was a significant correlation between the CDASI and all skin-specific QoL scores (lowest p=0.0377). Using the SF-36, DM was found to have significantly worse QoL scores than the general population with the exception of bodily pain (all subscore p values <0.01). Furthermore, DM had a significantly lower vitality score, representing energy level, compared to CLE, HTN, diabetes, and recent MI scores (lowest p=0.003). There was a significantly lower mental health score, representing overall mood, to all compared diseases except CLE and clinical depression (p values < 0.01 when significant). We found that DM produces more pruritus than CLE (p < 0.0001). Limitations A larger patient population needs to be studied to further assess QoL in DM patients. Conclusion We conclude that DM has a large impact on QoL, even when compared to other diseases, and that DM skin disease activity correlates with a poorer QoL. PMID:21722989

    1999-07-01

    Over the past fifteen years, engineers from Mine Ventilation Services, Inc. (MVS) have measured numerous friction factors at many different types of mining operations. The results of these measurements indicate that standardized friction factors referenced in most ventilation textbooks are greater than those measured in the field for similar airway support systems. Many referenced friction factors are still based on G.E. McElroy's classic paper Engineering Factors in the Ventilation of Metal Mines published in 1935. Most mechanized mines now incorporate airways that are larger, have more advanced support systems, and more uniform openings. This paper describes the measurement techniques and results from friction factor measurements taken during ventilation surveys at various mines with differing support systems. A comparison between textbook and measured values is also presented.

    1999-01-01

    In this stunning picture of the giant galactic nebula NGC 3603, the crisp resolution of NASA's Hubble Space Telescope captures various stages of the life cycle of stars in one single view. To the upper left of center is the evolved blue supergiant called Sher 25. The star has a unique circumstellar ring of glowing gas that is a galactic twin to the famous ring around the supernova 1987A. The grayish-bluish color of the ring and the bipolar outflows (blobs to the upper right and lower left of the star) indicates the presence of processed (chemically enriched) material. Near the center of the view is a so-called starburst cluster dominated by young, hot Wolf-Rayet stars and early O-type stars. A torrent of ionizing radiation and fast stellar winds from these massive stars has blown a large cavity around the cluster. The most spectacular evidence for the interaction of ionizing radiation with cold molecular-hydrogen cloud material are the giant gaseous pillars to the right of the cluster. These pillars are sculptured by the same physical processes as the famous pillars Hubble photographed in the M16 Eagle Nebula. Dark clouds at the upper right are so-called Bok globules, which are probably in an earlier stage of star formation. To the lower left of the cluster are two compact, tadpole-shaped emission nebulae. Similar structures were found by Hubble in Orion, and have been interpreted as gas and dust evaporation from possibly protoplanetary disks (proplyds). This true-color picture was taken on March 5, 1999 with the Wide Field Planetary Camera 2.

Then some of the definitions of life presently used are cited and briefly discussed, starting with the definition adopted by NASA as a general working definition. It is shown that this is too limited if one wishes to provide a broad encompassing definition, and some extensions of it are presented and discussed.

    A narrative review is made on the subject, highlighting the research conducted in our country under the direction and support of FUNDONAR Foundation, by the use of the World Health Organization transcultural quality of life measure (WHOQOL). Quality of life measurements have shown the strong impact of depression on people's well being, and also on all life aspects that they believe important, depending on their personal and cultural expectations. Quality of life was considerably poorer in depressed persons than in individuals with some other frequent chronic diseases. This underscores that its assessment can be used in health care decision making and resource allocation. The impact of depression was also found to be related to the seriousness of the episode. Quality of life measurements could be useful to assess the effectiveness of different mood disorder interventions, beyond symptomatology, with focus on individuals' main subjective opinions and concerns.

  5. The Biological Value of Protein.

    Moore, Daniel R; Soeters, Peter B

    2015-01-01

    The biological value of a protein extends beyond its amino-acid composition and digestibility, and can be influenced by additional factors in a tissue-specific manner. In healthy individuals, the slow appearance of dietary amino acids in the portal vein and subsequently in the systemic circulation in response to bolus protein ingestion improves nitrogen retention and decreases urea production. This is promoted by slow absorption when only protein is ingested (e.g. casein). When a full meal is ingested, whey achieves slightly better nitrogen retention than soy or casein, which is very likely achieved by its high content of essential amino acids (especially leucine). Elderly people exhibit 'anabolic resistance' implying that more protein is required to reach maximal rates of muscle protein synthesis compared to young individuals. Protein utilization in inflammatory or traumatic conditions increases substantially in the splanchnic tissues containing most of the immune system, and in wounds and growing tissues. This happens especially in the elderly, which often suffer from chronic inflammatory activity due to disease, physical inactivity and/or the aging process itself. Consequently, the proportion of protein absorbed in the gut and utilized for muscle protein synthesis decreases in these situations. This compromises dietary-protein-induced stimulation of muscle protein synthesis and ultimately results in increased requirements of protein (∼1.2 g/kg body weight/day) to limit gradual muscle loss with age. To optimally preserve muscle mass, physical exercise is required. Exercise has both direct effects on muscle mass and health, and indirect effects by increasing the utilization of dietary protein (especially whey) to enhance rates of muscle protein synthesis.

  7. A loaf of bread: Price and value.

    PubMed

    Pearn, J

    1998-03-01

    In the Western world, the basic staple of nutrition is bread. It evolved, from Neolithic times in Mesopotamia and the Levant, from flour made from natural hybrids of emmer and einkorn. Its form has changed from that of a dark, coarse and heavy loaf, baked in the ashes, to the enriched artistic breads of the late twentieth century. Its variety of forms conferred status on those who ate its refined and whitened form. The wheel of fashion and nutrition has turned full circle to the quality-controlled, vitamin and mineral-enriched wholemeal loaf of the new millennium to come. Bread has changed from a staple not simply of nutrition itself, but to that of a 'functional food' whose fibre confers protection against preventible disease. The bread of the new century thus will be both a food and a medicine. So fundamental to Western life is bread, that its price has long been the last item to remain controlled, when all else is left to the dictates of a free market economy. Bread is the fundamental unit of exchange and forms the last link in a chain of commodities which starts from items of luxury to those of survival itself. The price of bread can thus be used as a currency datum. As such, the price of a loaf of bread, and the minutes of labour needed to produce it, can be used to measure the economy, and to give a measured perspective of its influence on a community's history. Costs, throughout history, can be expressed in 'bread units'. As such, the latter forms an absolute index of the worth of other items, particularly a person's labour. As such, bread and its value forms a partly independent measure of inflationary and other social influences. Bread remains a fundamental part not only of nutrition, but of life itself. PMID:24394891

    A process is given for separating scandium from trivalent iron values. In this process, an aqueous nitric acid solution is contacted with a water- immiscible alkyl phosphate solution, the aqueous solution containing the values to be separated, whereby the scandium is taken up by the alkyl phosphate. The aqueous so1ution is preferably saturated with magnesium nitrate to retain the iron in the aqueous solution. (AEC)

  11. The value of snow cover

    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 only and not even the main outcome from snow cover use. The value of snow cover for agriculture, water resources, industry and transportation is so naturally inside the activities that is not often quantified. However, any considerations of adaptation strategies for climate change with changing snow conditions need such quantification.

    Objective Because self-rated health (SRH) is strongly associated with health outcomes, it is important to identify factors that individuals take into account when they assess their health. We examined the role of valued life activities (VLAs), the wide range of activities deemed to be important to individuals, in SRH assessments. Study Design and Setting Data were from 3 cohort studies of individuals with different chronic conditions rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and chronic obstructive pulmonary disease (COPD). Each cohorts data were collected through structured telephone interviews. Logistic regression analyses identified factors associated with ratings of fair/poor SRH. All analyses included sociodemographic characteristics, general and disease-specific health-related factors, and general measures of physical functioning. Results Substantial portions of each group rated their health as fair/poor (RA 37%, SLE 47%, COPD 40%). In each group, VLA disability was strongly associated with fair/poor health (RA: OR=4.44 [1.86,10.62]; SLE: OR=3.60 [2.10,6.16]; COPD: OR=2.76 [1.30,5.85], even after accounting for covariates. Conclusion VLA disability appears to play a substantial role in individual perceptions of health, over and above other measures of health status, disease symptoms, and general physical functioning.

  15. [The quality of life in schizophrenia].

    2015-09-01

    The World Health Organization defines quality of life as individuals' perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards, and concerns. Quality of life (QoL) is a concept, which reflects multiple as well subjective as objective dimensions. In patients with schizophrenia, quality of life has been negatively correlated with depressive and anxiety symptoms (results seem more unconvincing concerning positive symptoms and cognitive deficits); the remission of positive and negative symptoms has been associated with a better quality of life, but the persistence of depressive symptoms decreases quality of life even when patients were or not in remission; second generation antipsychotics significantly increase more quality of life than first generation antipsychotics; and psychotherapies (rehabilitation, case management...) improve quality of life. Several general and disease-specific QoL scales have been developed and successfully tested in patients with schizophrenia. The most appropriate disease-specific scale is the Quality of Life Scale (Heinrichs et al., 1984) since it takes patients' cognitive deficits into account and because it allows to subtly measuring the patients' subjective feeling during a hetero-evaluation. The Quality of Life Scale is a 21-item scale based on a semi-structured interview, which is comprised of four subscales: interpersonal relations, instrumental role functioning, intra-psychic foundations, and use of common objects and activities. It has been designed initially to assess deficit symptoms in schizophrenia. It is a simple and quite short tool, which is intended for the use as an outcome criterion, a measure of change and an indicator of the efficacy of therapeutic interventions. Convincing metrological qualities have been described: content, construct and nomological validities; inter-raters and test-retest fidelities; it is sensitive to change and to treatments and negatively correlated with symptoms (PANSS) and with clinical state (CGI). Two of the recent major antipsychotic efficacy trials, CATIE and CUtLASS, both adopted the Quality of Life Scale as a measure of quality of life. PMID:26341538

  17. The beginning of human life

    PubMed Central

    2008-01-01

    Introduction The Jewish religion is characterized by a strict association between faith and practical precept. Jewish law has two sections, the written and the oral tradition. The foundation of the written law and the origin of authority is the Torah, the first five books of the Scripture. It is an expression of Gods revelation, teaching and guiding humanity. The oral laws interpret, expand, and elucidate the written Torah and behavior patterns regulate new rules and customs. The main parts of the oral law are as follows: the Mishnah, the Talmud, Post-Talmudic Codes and. Responsa Literature. Discussion Life is a process that has a beginning and an end. The consensus about the time when human life really begins is still not reached among scientists, philosophers, ethicists, sociologists and theologizes. The scientific data suggested that a single developmental moment marking the beginning of human life does not exist. Current biological perspectives on when human life begins range through fertilization, gastrulation, to birth and even after. The development of a newborn is a smoothly continuous process. Results Procreation is acknowledged in the Bible to be the gift of God. The (Halachic) Jewish interpretation of when human life begins is extracted predominantly from procreation is acknowledged in the Bible to be the gift of God. The Jewish interpretation of when human life begins is extracted predominantly from The Halachic sources. The Bible does not make any other direct references regarding the beginning of human life. Conclusion While the Talmud gives the full status of humanness to a child at birth, the rabbinical writings have partially extended the acquisition of humanness to the 13th postnatal day of life for full-term infants. The Babylonian Talmud Yevamot 69b states that: the embryo is considered to be mere water until the fortieth day. Afterwards, it is considered subhuman until it is born. The issues of abortion, embryo research, multifetal reduction and cloning will be discussed according to Jewish Law perspectives. Life is a process that has a beginning and an end. The consensus about the time when human life really begins is still not reached among scientists, philosophers, ethicists, sociologists and theologizes. The scientific data suggested that a single developmental moment marking the beginning of human life does not exist.

  18. Life of Pi and the moral wound.

    PubMed

    Allen, Thomas E

    2014-12-01

    The "moral wound," rendered symbolically in the form of the tiger in Life of Pi, is a complex trauma in which the victim, in order to survive in life-threatening circumstances, commits an ethical transgression against his or her deeply held values. Pi experiences such a trauma and deals with it by dissociating it in the form of the tiger and then has to simultaneously both preserve the tiger and wish it to disappear. Jonathan Shay's work relating the experiences of returning Vietnam veterans to Homer's Odyssey is used to further an understanding of both Life of Pi and American soldiers returning from the wars in Iraq and Afghanistan. Reasons are considered for the possible delayed effect of trauma as a factor in the increased suicide rate of older veterans. Finally, the concept of the "moral wound" is discussed, with an eye to its treatment. PMID:25503752

    A new determination of the (109)Cd half-life was made by a time series of measurements of an aqueous sample using a re-entrant type ionisation chamber. The measurement campaign covered a period of 6 years or approximately 4.7 half-lives of (109)Cd. The resulting value of 462.1 (3) days is in good agreement with the recently published values of 462.29 (30) days and 462.3 (8) days. This new half-life determination will allow evaluators to specify a recommended value of the (109)Cd half-life making it more accurate and precise. PMID:26640235

  20. Quality of life: does measurement help?

    PubMed

    Bergsma, J; Engel, G L

    1988-01-01

    'Quality of life' is a very frequently applied concept nowadays. One may doubt whether everyone has the same connotation in mind while using this expression and why 'quality of life' attracts so much attention. Is the idea a very old one or is it a new and noble value? It is argued here that changes such as in the number of aged people and of chronically disabled people, combined with spectacular developments in medical technology and with a rise in knowledge and assertivity, created an increased awareness of 'quality of life' and its interaction with medicine. Moreover, limitations to budgets and technological developments trigger an interest in new arguments. 'Quality of life' plays an increasing role in all sorts of medical decisions, be it in policy decisions or in individual clinical decisions, be it formally assessed or implicitly weighted. A number of examples is briefly described to illustrate the very broad and diffuse use of quality of life as a criterion. Subsequently we have tried to operationalize the concept on 4 levels: macro, meso, personal and physical. The macro level applies to the meaning of life in a society; assessments of quality of life play a role, for instance, in discussions on euthanasia and in political decisions on medical investments. Examples of the meso level are the hospital, with its internal processes and its ties to the rest of the world, but also the patient in his social environment. On the personal level the individual's frames of reference on health, illness, future, pain and hope - both of the patient and the doctor - are being considered. It is argued that legitimation of important decisions, investments and interventions requires measurement of quality of life in an objective way and on different levels. Quantifying quality, however, appears hardly feasible. Therefore 'quality of life' is frequently measured at the fourth level only, the level of physical activities. Confining measurement to the measurable induces the question of whether it really is 'quality of life' that is being quantified. Still, results from such measurements can be of help in decision making. Who decides in clinical situations and in what way should 'quality of life' be involved in decision making? In one solution, perhaps the old fashioned one, the doctor takes all responsibility, possibly from a paternalistic ideal. Conversely, should the doctor behave in a completely non-directive way, full autonomy is given to the patient.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:10291118

    An interdisciplinary study of water realized in High Schools of Bucharest and Oradea The paper studies the importance and the properties of water from different points of view. In the curricula the water is studied by sciences as Chemistry, Physics, Biology, Geography and Environmental Sciences, but the water is important also for History, Economy, Sociology, Religion, Arts, Sport, and so on. The students from "C.A.Rosetti High-school" from Bucharest and "Mihai Viteazul" from Oradea, guided by their teachers realized some interesting studies about water as physical, biological and chemical properties but also about economical importance of the water in our life, or about the aesthetic value of the water. The final products (CD-s, PowerPoint presentations, movies, drawings, posters and so on) are realized during the lessons from the curricula but also in non-formal education activities. So the students accomplished some research about water in specialised institutes, but also in the middle of nature. They studied the plants, insects and animals living in wetland areas. The students went to the springs, rivers , lakes, the Danube Delta and to the Black Sea and after that they organised workshops and seminars in order to disseminate their work.

    The decay of Po 218 is accompanied by the emission of 6.00-MeV alpha particles. The most suitable method for studying it is the alphaspectrometric method. To generate radon, the source for RaA, the authors used a preparation of Ra 226 with a high degree of purity. Targets were prepared for measuring the half-life on a radon setup. Approximately 30 sec after holding in a radon atmosphere the target was placed with the polonium deposited on it into a vacuum chamber. It was noted that the intensity of the peak at 6.70 MeV decreases at the same rate as the decay of Po 218, and the ratio of the intensities of their peaks was equal to 0.037 +/- 0.007%. The spectra (alpha was analyzed on an LP-4900 analyzer. The values of the half-life that were obtained are in good agreement with the values obtained previously.

  10. Inversion Concept of the Origin of Life

    NASA Astrophysics Data System (ADS)

    Kompanichenko, V. N.

    2012-06-01

    The essence of the inversion concept of the origin of life can be narrowed down to the following theses: 1) thermodynamic inversion is the key transformation of prebiotic microsystems leading to their transition into primary forms of life; 2) this transformation might occur only in the microsystems oscillating around the bifurcation point under far-from-equilibrium conditions. The transformation consists in the inversion of the balance "free energy contribution / entropy contribution", from negative to positive values. At the inversion moment the microsystem radically reorganizes in accordance with the new negentropy (i.e. biological) way of organization. According to this approach, the origin-of-life process on the early Earth took place in the fluctuating hydrothermal medium. The process occurred in two successive stages: a) spontaneous self-assembly of initial three-dimensional prebiotic microsystems composed mainly of hydrocarbons, lipids and simple amino acids, or their precursors, within the temperature interval of 100-300°C (prebiotic stage); b) non-spontaneous synthesis of sugars, ATP and nucleic acids started at the inversion moment under the temperature 70-100°C (biotic stage). Macro- and microfluctuations of thermodynamic and physico-chemical parameters able to sustain this way of chemical conversion have been detected in several contemporary hydrothermal systems. A minimal self-sufficient unit of life on the early Earth was a community of simplest microorganisms (not a separate microorganism).

  11. Uncertainty of Monetary Valued Ecosystem Services – Value Transfer Functions for Global Mapping

    2016-01-01

    Growing demand of resources increases pressure on ecosystem services (ES) and biodiversity. Monetary valuation of ES is frequently seen as a decision-support tool by providing explicit values for unconsidered, non-market goods and services. Here we present global value transfer functions by using a meta-analytic framework for the synthesis of 194 case studies capturing 839 monetary values of ES. For 12 ES the variance of monetary values could be explained with a subset of 93 study- and site-specific variables by utilizing boosted regression trees. This provides the first global quantification of uncertainties and transferability of monetary valuations. Models explain from 18% (water provision) to 44% (food provision) of variance and provide statistically reliable extrapolations for 70% (water provision) to 91% (food provision) of the terrestrial earth surface. Although the application of different valuation methods is a source of uncertainty, we found evidence that assuming homogeneity of ecosystems is a major error in value transfer function models. Food provision is positively correlated with better life domains and variables indicating positive conditions for human well-being. Water provision and recreation service show that weak ownerships affect valuation of other common goods negatively (e.g. non-privately owned forests). Furthermore, we found support for the shifting baseline hypothesis in valuing climate regulation. Ecological conditions and societal vulnerability determine valuation of extreme event prevention. Valuation of habitat services is negatively correlated with indicators characterizing less favorable areas. Our analysis represents a stepping stone to establish a standardized integration of and reporting on uncertainties for reliable and valid benefit transfer as an important component for decision support.

    Customer value theory's discovery has established to take customer and even customer value as the center position for research of marketing, which is good progress of marketing theory. However, in the past researches for customer value emphasized customer perceived value, there was no good answer on which customers perceived with what scale. This paper states that customer perceived value is established in value transmission mechanism of its rear, which is based on the role of consumption values. With a market environment's change, and the strength of consumer's sovereignty consciousness, especially when personal consumption is identified and developed to become a mainstream consume culture in nowadays society, the role of the transmission is increasingly in evidence. Studies of consumeption values are to deepen customer value theory.

    In 2010, the Venter lab announced that it had created the first bacterium with an entirely synthetic genome. This was reported to be the first instance of artificial life, and in the ethical and policy discussions that followed it was widely assumed that the creation of artificial life is in itself morally significant. We cast doubt on this assumption. First we offer an account of the creation of artificial life that distinguishes this from the derivation of organisms from existing life and clarify what we mean in asking whether the creation of artificial life has moral significance. We then articulate and evaluate three attempts to establish that the creation of artificial life is morally significant. These appeal to (1) the claim that the creation of artificial life involves playing God, as expressed in three distinct formulations; (2) the claim that the creation of artificial life will encourage reductionist attitudes toward the living world that undermine the special moral value accorded to life; and (3) the worry that artificial organisms will have an uncertain functional status and consequently an uncertain moral status. We argue that all three attempts to ground the moral significance of the creation of artificial life fail, because none of them establishes that the creation of artificial life is morally problematic in a way that the derivation of organisms from existing life forms is not. We conclude that the decisive moral consideration is not how life is created but what non-genealogical properties it possesses. PMID:23810562

    Despite the successful growth of the hospice movement during the past 30 years in the United States, almost 85% of Americans continue to die in hospitals or nursing homes. While the benefits of palliative care principles are well established, palliative care interventions remain underused in clinical practice in the settings in which most Americans die. Our premise is that physicians as a group perpetuate end-of-life suffering rather than ease the transition from life to death. We also believe that maintaining quality of life (QOL) at the end of life requires a multidimensional approach orchestrated by physicians drawing on the full range of available physical, psychological, social, and spiritual interventions. This article defines the meaning of QOL at the end of life and then examines the ramifications of failing to attend to QOL concerns in dying patients. It reviews strategies that physicians can use to advance palliative care approaches, thereby reducing terminally ill patients' suffering in the institutions in which most die. PMID:11126840

    2013-01-01

    We examine how family, money, and health explain variation in life satisfaction over the life cycle across seven global regions using data from the World Values Survey. With a life domain approach, we study whether the importance of the life domains varies by region and age groups and whether the variation explained by each factor is due to the magnitude or prevalence of each factor. Globally, family, money, and health explain a substantial fraction of life satisfaction, increasing from 12 percent in young adulthood to 15 percent in mature adulthood. Health is the most important factor, and its importance increases with age. Income is unimportant above age 50. Remarkably, the contribution of family is small across ages. Across regions health is most important in the wealthier, and income in the poorer regions of the world. Family explains a substantial fraction of life satisfaction only in Western Europe and Anglophone countries. Findings highlight that the population-level importance of family, money, and health in explaining variation in life satisfaction across regions is mainly attributable to the individual-level life satisfaction differences between people of different statuses rather than differences in the distribution of various states such as poor health across regions.

    Value of information (VOI) provides the ability to identify and prioritize useful information gathering for a geothermal prospect, either hydrothermal or for enhanced geothermal systems. Useful information provides a value greater than the cost of the information; wasteful information costs more than the expected value of the information. In this project we applied and refined VOI methodologies on selected geothermal prospects.

    2012-01-01

    This paper attempts to quantify the social, private, and public-finance values of reducing obesity through pharmaceutical and medical interventions. We find that the total social value of bariatric surgery is large for treated patients, with incremental social cost-effectiveness ratios typically under $10,000 per life-year saved. On the other hand, pharmaceutical interventions against obesity yield much less social value with incremental social cost-effectiveness ratios around $50,000. Our approach accounts for: competing risks to life expectancy; health care costs; and a variety of non-medical economic consequences (pensions, disability insurance, taxes, and earnings), which account for 20% of the total social cost of these treatments. On balance, bariatric surgery generates substantial private value for those treated, in the form of health and other economic consequences. The net public fiscal effects are modest, primarily because the size of the population eligible for treatment is small while the net social effect is large once improvements in life expectancy are taken into account.

    Followership is an emerging concept based on human factors science. It describes a set of skills and behaviours that help improve team performance. An effective leader creates vision, sets direction and enables a culture in which others can thrive and work together to deliver the goals. Like leadership, good followership is increasingly being recognised as an important component for high performance. Good followership is based on good communication and 'upward influencing' (Willson 2012). This article discusses the concept arid provides scenarios to illustrate examples of good and poor followership, and how they affect care. PMID:23734416

  11. Value of global weather sensors

    SciTech Connect

    Canavan, G.H.

    1998-12-23

    Long-range weather predictions have great scientific and economic potential, but require precise global observations. Small balloon transponders could serve as lagrangian trace particles to measure the vector wind, which is the primary input to long-range numerical forecasts. The wind field is difficult to measure; it is at present poorly sampled globally. Distance measuring equipment (DME) triangulation of signals from roughly a million transponders could sample it with sufficient accuracy to support {approximately} two week forecasts. Such forecasts would have great scientific and economic potential which is estimated below. DME uses small, low-power transmitters on each transponder to broadcast short, low-power messages that are detected by several small receivers and forwarded to the ground station for processing of position, velocity, and state information. Thus, the transponder is little more than a balloon with a small radio, which should only weigh a few grams and cost a few dollars.

  12. Absolute Planck Values: Moving Beyond the Arbitrary Assignment of Unity

    NASA Astrophysics Data System (ADS)

    Laubenstein, John

    2008-03-01

    Planck Values provide a valuable tool in efforts to understand basic universal relationships; however, they fall short of having any truly intrinsic value. Planck Values come with the assumption that unity can be assigned to up to five of the fundamental universal constants. While constraining these values to unity may be convenient, it by no means ensures that intelligent life anywhere in the universe would make the same assumptions. Further, the peculiar value of the inverse fine structure constant of 137 suggests that it is naive to assume that any of the physical constants are equal to unity or any other simplistic value. Through an analysis of gravitation and electrostatic force, the IWPD Research Center has derived a logical argument for a revised set of Planck Values that represent absolute values with true universal significance. Of greatest importance, is a recalculated Planck Mass that serves as a truly fundamental unit of mass at the quantum scale. This finding contrasts with the significantly large value associated with the current Planck Mass and provides new information that may be critical in the search to unify General Relativity with Quantum Mechanics.

    Data play a central role in most fields of science. In recent years, the amount of data from experiment, observation, and simulation has increased rapidly and data complexity has grown. Also, communities and shared storage have become geographically more distributed. Therefore, methods and techniques applied to scientific data need to be revised and partially be replaced, while keeping the community-specific needs in focus. The German Helmholtz Association project "Large Scale Data Management and Analysis" (LSDMA) aims to maximize the efficiency of data life cycles in different research areas, ranging from high energy physics to systems biology. In its five Data Life Cycle Labs (DLCLs), data experts closely collaborate with the communities in joint research and development to optimize the respective data life cycle. In addition, the Data Services Integration Team (DSIT) provides data analysis tools and services which are common to several DLCLs. This paper describes the various activities within LSDMA and focuses on the work performed in the DLCLs.

    2012-09-01

    This paper aims to inspire experimentalists to carry out proposed new chiroptical experiments springing from the theoretical study of the role of parity violation in the origin of biomolecular homochirality and to provide a brief update on the current status of calculations of the electroweak parity-violating energy difference (PVED) between enantiomers. If the PVED did select life's handedness, we would expect to find life on other planets consistently using the same hand as terrestrial biochemistry. Much more importantly, even finding the "wrong" hand (rather than a racemic mixture) on another planet could be the homochiral signature of life, and we discuss our proposal for chiroptical detection of life on extra-solar planets. The PVED may also have an exciting future as a "molecular footprint" of fundamental physics: comparison of calculated PVEDs with measured values could one day allow chemists to do "table-top particle physics" more cheaply with improved chiroptical techniques instead of ever larger particle accelerators. We discuss our proposed chiroptical method to measure the PVED by using molecular beams. To our knowledge, optical rotation has not yet been measured in molecular beams, but the rewards of doing so include a host of other "first ever" results in addition to measurement of the PVED.

  17. Psychosomatic medicine and the philosophy of life.

    PubMed

    2010-01-01

    Basing ourselves on the writings of Hans Jonas, we offer to psychosomatic medicine a philosophy of life that surmounts the mind-body dualism which has plagued Western thought since the origins of modern science in seventeenth century Europe. Any present-day account of reality must draw upon everything we know about the living and the non-living. Since we are living beings ourselves, we know what it means to be alive from our own first-hand experience. Therefore, our philosophy of life, in addition to starting with what empirical science tells us about inorganic and organic reality, must also begin from our own direct experience of life in ourselves and in others; it can then show how the two meet in the living being. Since life is ultimately one reality, our theory must reintegrate psyche with soma such that no component of the whole is short-changed, neither the objective nor the subjective. In this essay, we lay out the foundational components of such a theory by clarifying the defining features of living beings as polarities. We describe three such polarities: 1) Being vs. non-being: Always threatened by non-being, the organism must constantly re-assert its being through its own activity. 2) World-relatedness vs. self-enclosure: Living beings are both enclosed with themselves, defined by the boundaries that separate them from their environment, while they are also ceaselessly reaching out to their environment and engaging in transactions with it. 3) Dependence vs. independence: Living beings are both dependent on the material components that constitute them at any given moment and independent of any particular groupings of these components over time.We then discuss important features of the polarities of life: Metabolism; organic structure; enclosure by a semi-permeable membrane; distinction between "self" and "other"; autonomy; neediness; teleology; sensitivity; values. Moral needs and values already arise at the most basic levels of life, even if only human beings can recognize such values as moral requirements and develop responses to them. PMID:20089202

    Koonin, Eugene V

    2014-07-01

    All life on earth can be naturally classified into cellular life forms and virus-like selfish elements, the latter being fully dependent on the former for their reproduction. Cells are reproducers that not only replicate their genome but also reproduce the cellular organization that depends on semipermeable, energy-transforming membranes and cannot be recovered from the genome alone, under the famous dictum of Rudolf Virchow, Omnis cellula e cellula. In contrast, simple selfish elements are replicators that can complete their life cycles within the host cell starting from genomic RNA or DNA alone. The origin of the cellular organization is the central and perhaps the hardest problem of evolutionary biology. I argue that the origin of cells can be understood only in conjunction with the origin and evolution of selfish genetic elements. A scenario of precellular evolution is presented that involves cohesion of the genomes of the emerging cellular life forms from primordial pools of small genetic elements that eventually segregated into hosts and parasites. I further present a model of the coevolution of primordial membranes and membrane proteins, discuss protocellular and non-cellular models of early evolution, and examine the habitats on the primordial earth that could have been conducive to precellular evolution and the origin of cells.

    2003-11-01

    Agricultural and animal scientists need to embrace a new vision beyond the single-minded existing pursuit of biological efficiency. The public in the West is no longer concerned solely with cheap food. Other paramount issues define quality of life, including: health and safety of foods; nutritional value; traditional, regional, locally produced, and organic foods; animal welfare; sustainable farming, environment, and rural resources. The paper provides examples of how the credibility of animal scientists has been lost due to some recent unethical behavior. Research, teaching and application of agricultural and animal science, especially of biotechnology, need to be reshaped into a new "Quality of Life Agricultural Era" to replace the "Era of Intensification." This new era will need fresh assumptions, beliefs and leadership to match the emerging social agenda of the 21st century. Animal scientists have a special role in implementing this new plausibility structure. PMID:14601893

    A recent literature review of meaning and bereavement suggests a conceptual distinction between sense-making, or the integration of a loss with beliefs and narratives, and life significance, or perception of value associated with an aspect of one's life experience. The present study aims to develop and validate a new measure: the Perceived Life Significance Scale (PLSS). Exploratory (n = 353) and confirmatory (n = 483) factor analyses support three factors: active pursuit of goals and activities; emptiness/insignificance (reverse-scored); and receptivity to beauty in everyday life. The PLSS demonstrates convergent and discriminant validity with respect to general measures of meaning, negative affect, depression, and sense-making. PMID:25679540

    Neo-Darwinian evolutionary theory explains how the appearance of purposive design in the adaptations of living organisms can have come about without their intentionally being designed. The explanation relies crucially on the possibility of certain physical processes: mainly, gene replication and natural selection. In this paper, I show that for those processes to be possible without the design of biological adaptations being encoded in the laws of physics, those laws must have certain other properties. The theory of what these properties are is not part of evolution theory proper, yet without it the neo-Darwinian theory does not fully achieve its purpose of explaining the appearance of design. To this end, I apply constructor theory's new mode of explanation to express exactly within physics the appearance of design, no-design laws, and the logic of self-reproduction and natural selection. I conclude that self-reproduction, replication and natural selection are possible under no-design laws, the only non-trivial condition being that they allow digital information to be physically instantiated. This has an exact characterization in the constructor theory of information. I also show that under no-design laws an accurate replicator requires the existence of a ‘vehicle’ constituting, together with the replicator, a self-reproducer. PMID:25589566

    A brief investigation of the effects of oxidation on the calorific values of three Turkish lignite samples has been made. The lignite samples have been vacuum dried and oxidized in pure oxygen at 35, 45, and 55 C at 100 kPa for 10 days. The calorific values of the oxidized and unoxidized samples have been measured. A relation has been observed between the extent of oxidation and decrease in calorific value. Various possibilities of modeling the relation have been explored.

    The argument that the earth's early ocean was up to two times modern salinity was published in 'Nature' and presented at the 1998 Annual Meeting of the Geological Society of America in Toronto. The argument is bolstered by chemical data for fluid inclusions in Archean black smokers. The inclusions were 1.7 times the modern salinity causing the authors to interpret the parent fluids as evaporite brines (in a deep marine setting). I reinterpreted the data in terms of the predicted value of high Archean salinities. If the arguments I presented are on track, early life was either halophilic or non-marine. Halophiles are not among the most primitive organisms based on RNA sequencing, so here is an a priori argument that non-marine environments may have been the site of most early biologic evolution. This result carries significant implications for the issue of past life on Mars or current life on the putative sub-ice oceans on Europa and possibly Callisto. If the Cl/H2O ratio on these objects is similar to that of the earth, then oceans and oceanic sediments are probably not the preferred sites for early life. On Mars, this means that non-marine deposits such as caliche in basalt may be an overlooked potential sample target.

  18. Integrating Varieties of Life Course Concepts

    PubMed Central

    2012-01-01

    A body of work referred to as the “life course” framework (also known as “life course theory,” the “life course paradigm,” and the “life course perspective”) has been increasingly used to motivate and justify the examination of the relationships among variables in social and behavioral science, particularly in the study of population health and aging. Yet, there is very little agreement on what some of these concepts mean, and there is hardly any agreement on what the “life course” is. This article focuses on the different ways in which the concept oflife course” is used in the contemporary study of aging and human development, particularly with regard to health and well-being. Clarification is given for how “life course” is distinguished from “life span” and “life cycle,” among other “life” words. This work reviews the conceptual literature on the life course, beginning with its formative years in the 1960s and 1970s, through to the present time. Detailed research of several literatures across disciplines revealed five different uses of the term “life course”: (a) life course as time or age, (b) life course as life stages, (c) life course as events, transitions, and trajectories, (d) life course as life-span human development, and (e) life course as early life influences (and their cumulation) on later adult outcomes. To the extent the concept of life course has a multiplicity of meanings that are at variance with one another, this is problematic, as communication is thereby hindered. On the other hand, to the extent the concept of life course involves a rich tapestry of different emphases, this is a good thing, and the diversity of meanings should be retained. This paper proposes a conceptual integration based in part on Riley’s age stratification model that resolves the various meanings of life course into one general framework. Coupled with a demographic conceptualization of the life course, this framework embeds the concept oflife course” within a broader perspective of life-span development. This framework is proposed as an integrated perspective for studying the causes and consequences oflife course events and transitions” and understanding the manner by which “life events” and the role transitions they signify influence the life-span development of outcomes of interest across stages of the life cycle.

    1980-04-01

    Bilogical resources have always existed and been used, but an integrated approach to bioresource as a way for man to work with nature is emerging to replace the exploitation of nonrenewable materials and resources. A society oriented around bioresources could provide a more-equitable distribution of basic needs of an expanding population without exceeding the planet's capacity. Green plants contribute 60% of this resource with the remainder equally divided between animals and microorganisms. Assistance to Third World countries could become more effective with a shift from linear technology transfers to bioresource development. Three lines of approach are suggested: (1) recycling wastes and materials to increase the bio-yield, (2) research on enzyme technology and nitrogen fixation, and (3) a total systems approach to bioresource management. An inventory of bioresource characteristics underlines the need for new perceptions to deal with the fact that it is alive and that man's cooperation with the environment is required. (DCK)

    2016-03-01

    The half-life of (234)U has been measured using a novel approach. In this method, a uranium material was chemically purified from its thorium decay product at a well-known time. The ingrowth of the (230)Th daughter product in the material was followed by measuring the accumulated (230)Th daughter product relative to its parent (234)U nuclide using inductively coupled plasma mass spectrometry. Then, the (234)U decay constant and the respective half-life could be calculated using the radioactive decay equations based on the n((230)Th)/n((234)U) amount ratio. The obtained (234)U half-life is 244 900 ± 670 years (k = 1), which is in good agreement with the previously reported results in the literature with comparable uncertainty. The main advantages of the proposed method are that it does not require the assumption of secular equilibrium between (234)U and (238)U. Moreover, the calculation is independent from the (238)U half-life value and its uncertainty. The suggested methodology can also be applied for the remeasurement of the half-lives of several other long-lived radionuclides. PMID:26823129

    Gero, John S.; Kannengiesser, Udo

    This paper presents a view of innovation as a process that changes value systems of producers and adopters of creative design ideas. Value systems comprise interpretations of the function and behaviour of an artefact, encapsulated in a producers or adopters situation. Changes in these value systems can be induced using distinct classes of processes. The paper shows that innovation requires changes in the encapsulated value systems of both producers and adopters, driven by their interactions with the artefact and with each other. This provides the basis for a computational, agent-based framework for testing models of innovation.

  3. Towards a definition of life.

    Macklem, Peter T; Seely, Andrew

    2010-01-01

    This article offers a new definition of life as a "self-contained, self-regulating, self-organizing, self-reproducing, interconnected, open thermodynamic network of component parts which performs work, existing in a complex regime which combines stability and adaptability in the phase transition between order and chaos, as a plant, animal, fungus, or microbe." Open thermodynamic networks, which create and maintain order and are used by all organisms to perform work, import energy from and export entropy into the environment. Intra- and extracellular interconnected networks also confer order. Although life obeys the laws of physics and chemistry, the design of living organisms is not determined by these laws, but by Darwinian selection of the fittest designs. Over a short range of normalized energy consumption, open thermodynamic systems change from deeply ordered to chaotic, and life is found in this phase transition, where a dynamic balance between stability and adaptability allows for homeokinesis. Organisms and cells move within the phase transition with changes in metabolic rate. Seeds, spores and cryo-preserved tissue are well within the ordered regime, while health probably cannot be maintained with displacements into the chaotic regime. Understanding life in these terms may provide new insights into what constitutes health and lead to new theories of disease. PMID:20639603

    Life Investigation For Enceladus (LIFE) presents a low-cost sample return mission to Enceladus, a body with high astrobiological potential. There is ample evidence that liquid water exists under ice coverage in the form of active geysers in the "tiger stripes" area of the southern Enceladus hemisphere. This active plume consists of gas and ice particles and enables the sampling of fresh materials from the interior that may originate from a liquid water source. The particles consist mostly of water ice and are 1-10?? in diameter. The plume composition shows H(2)O, CO(2), CH(4), NH(3), Ar, and evidence that more complex organic species might be present. Since life on Earth exists whenever liquid water, organics, and energy coexist, understanding the chemical components of the emanating ice particles could indicate whether life is potentially present on Enceladus. The icy worlds of the outer planets are testing grounds for some of the theories for the origin of life on Earth. The LIFE mission concept is envisioned in two parts: first, to orbit Saturn (in order to achieve lower sampling speeds, approaching 2 km/s, and thus enable a softer sample collection impact than Stardust, and to make possible multiple flybys of Enceladus); second, to sample Enceladus' plume, the E ring of Saturn, and the Titan upper atmosphere. With new findings from these samples, NASA could provide detailed chemical and isotopic and, potentially, biological compositional context of the plume. Since the duration of the Enceladus plume is unpredictable, it is imperative that these samples are captured at the earliest flight opportunity. If LIFE is launched before 2019, it could take advantage of a Jupiter gravity assist, which would thus reduce mission lifetimes and launch vehicle costs. The LIFE concept offers science returns comparable to those of a Flagship mission but at the measurably lower sample return costs of a Discovery-class mission. PMID:22970863

  9. An Aristotelian Account of Minimal Chemical Life

    NASA Astrophysics Data System (ADS)

    Bedau, Mark A.

    2010-12-01

    This paper addresses the open philosophical and scientific problem of explaining and defining life. This problem is controversial, and there is nothing approaching a consensus about what life is. This raises a philosophical meta-question: Why is life so controversial and so difficult to define? This paper proposes that we can attribute a significant part of the controversy over life to use of a Cartesian approach to explaining life, which seeks necessary and sufficient conditions for being an individual living organism, out of the context of other organisms and the abiotic environment. The Cartesian approach contrasts with an Aristotelian approach to explaining life, which considers life only in the whole context in which it actually exists, looks at the characteristic phenomena involving actual life, and seeks the deepest and most unified explanation for those phenomena. The phenomena of life might be difficult to delimit precisely, but it certainly includes life's characteristic hallmarks, borderline cases, and puzzles. The Program-Metabolism-Container (PMC) model construes minimal chemical life as a functionally integrated triad of chemical systems, which are identified as the Program, Metabolism, and Container. Rasmussen diagrams precisely depict the functional definition of minimal chemical life. The PMC model illustrates the Aristotelian approach to life, because it explains eight of life's hallmarks, one of life's borderline cases (the virus), and two of life's puzzles.

    The methodology of developing finite life distributional Goodman diagrams and surfaces is described for presenting allowable combinations of alternating stress and mean stress to the design engineer. The combined stress condition is that of an alternating bending stress and a constant shear stress. The finite life Goodman diagrams and surfaces are created from strength distributions developed at various ratios of alternating to mean stress at particular cycle life values. The conclusions indicate that the Von Mises-Hencky ellipse, for cycle life values above 1000 cycles, is an adequate model of the finite life Goodman diagram. In addition, suggestions are made which reduce the number of experimental data points required in a fatigue data acquisition program.

  14. The social value of clinical research

    PubMed Central

    2014-01-01

    Background International documents on ethical conduct in clinical research have in common the principle that potential harms to research participants must be proportional to anticipated benefits. The anticipated benefits that can justify human research consist of direct benefits to the research participant, and societal benefits, also called social value. In first-in-human research, no direct benefits are expected and the benefit component of the risks-benefit assessment thus merely exists in social value. The concept social value is ambiguous by nature and is used in numerous ways in the research ethics literature. Because social value justifies involving human participants, especially in early human trials, this is problematic. Discussion Our analysis and interpretation of the concept social value has led to three proposals. First, as no direct benefits are expected for the research participants in first-in-human trials, we believe it is better to discuss a risk- value assessment instead of a risk - benefit assessment. This will also make explicit the necessity to have a clear and common use for the concept social value. Second, to avoid confusion we propose to limit the concept social value to the intervention tested. It is the expected improvement the intervention can bring to the wellbeing of (future) patients or society that is referred to when we speak about social value. For the sole purpose of gaining knowledge, we should not expose humans to potential harm; the ultimate justification of involving humans in research lies in the anticipated social value of the intervention. Third, at the moment only the validity of the clinical research proposal is a prerequisite for research to take place. We recommend making the anticipated social value a prerequisite as well. Summary In this paper we analyze the use of the concept social value in research ethics. Despite its unavoidable ambiguity, we aim to find a best use of the concept, subject to its role in justifying involving humans in first-in-human research. PMID:25189994

    2006-10-01

    The objective of this study was to estimate the value of pregnancy for dairy cows. Effects of the stage of gestation, stage of lactation, lactation number, milk yield, milk price, replacement heifer cost, probability of pregnancy, probability of involuntary culling, and breeding decisions were studied. A bioeconomic model was used, and breeding and replacement decisions were optimized. A general Holstein herd in the United States was modeled. The average value of a new pregnancy was $278. The value of a new pregnancy increased with days in milk early in lactation but typically decreased later in lactation. Relatively high-producing cows and first-lactation cows reached greater values, and their values peaked later in lactation. The average cost of a pregnancy loss (abortion) was $555. The cost of a pregnancy loss typically increased with gestation length. Sensitivity analyses showed that an increased probability of pregnancy, an increased persistency of milk yield, and a smaller replacement heifer cost greatly reduced the average value of a pregnancy. The value of a new pregnancy was negative for relatively high-producing first-lactation cows when persistency of lactation and the probability of pregnancy were increased. Breeding was delayed when the value of pregnancy was negative. Changes in milk price, absolute milk yield, and probability of involuntary culling had less effect on the value of pregnancy. The value of pregnancy and optimal breeding decisions for individual cows were greatly dependent on the predicted daily milk yield for the remaining period of lactation. An improved understanding of the value of pregnancy may support decision making in reproductive management when resources are limited. PMID:16960063

    This study estimates the capacity value of a concentrating solar power (CSP) plant at a variety of locations within the western United States. This is done by optimizing the operation of the CSP plant and by using the effective load carrying capability (ELCC) metric, which is a standard reliability-based capacity value estimation technique. Although the ELCC metric is the most accurate estimation technique, we show that a simpler capacity-factor-based approximation method can closely estimate the ELCC value. Without storage, the capacity value of CSP plants varies widely depending on the year and solar multiple. The average capacity value of plants evaluated ranged from 45%?90% with a solar multiple range of 1.0-1.5. When introducing thermal energy storage (TES), the capacity value of the CSP plant is more difficult to estimate since one must account for energy in storage. We apply a capacity-factor-based technique under two different market settings: an energy-only market and an energy and capacity market. Our results show that adding TES to a CSP plant can increase its capacity value significantly at all of the locations. Adding a single hour of TES significantly increases the capacity value above the no-TES case, and with four hours of storage or more, the average capacity value at all locations exceeds 90%.

    One possible definition for the origin of life on Earth is the time at which the interval between devastating environmental insults by impact exceeded the timescale for establishing self-replicating proto-organisms. A quantitative relationship for the Hadean (pre-3,800 Myr ago) and Early Archean (3,800 to 3,400 Myr) impact flux can be derived from the lunar and terrestrial impact records. Also, the effects of impact-related processes on the various environments proposed for abiogenesis (the development of life through chemical evolution from inorganic materials) can be estimated. Using a range of plausible values for the timescale for abiogenesis, the interval in time when life might first have bootstrapped itself into existence can be found for each environment. We find that if the deep marine hydrothermal setting provided a suitable site, abiogenesis could have happened as early as 4,000 to 4,200 Myr ago, whereas at the surface of the Earth abiogenesis could have occurred between 3,700 and 4,000 Myr.

There is no effective treatment or cure to SSc, so it is important improve global health of these patients and reduce morbidity and mortality associated with SSc. It was made a literature review about quality of life in patients with SSc, regarding the several factors that should be considered and evaluated when attending to SSc patients. It was also considered the validated scales and questionnaires used to measure outcomes in patients with SSc. We concluded that it is important to have an interdisciplinary approach to SSc patients considering the patient's cognitive representations of the disease and what they value most like mobility and hand function, pain, fatigue, sleep, depression and body image.

Moral and ethical concepts result from an evaluation process of human behavior and social relationships. From the marxist insight of people it is known that this is historically concrete and not eternally existing in the nature of man. It is based on concrete people within concrete social situations. Moral values are dependent on social concepts and include human motivations. There is a close relationship between human needs and interests on the one hand and ethical values on the other hand. In abortion too, the single decision of the person does not constitute an ethical value. Abortion cannot be considered independent from the woman, nor from social reality. Reasons for legal abortion have changed through the years according to social needs; before and after World War II poverty, hardship, malnutrition; today it mainly is a question of woman's need for equality in education, profession, and family. Population policies play a role: "soldiers for Hitler" during World War II; preservation of the German race; influx of foreign people with large families. Ethical naturalism "survival of the fittest" is rejected. "Human life" cannot be separated from "developing human life"; zygote, embryo, fetus and newborn are all inseparable stages in human life. A newborn child is not purely biological, like an animal; social aspects are involved. Human nature is a product of history. The developing embryo has no significance as a primary basis for induced abortion but secondarily serves only to determine the optimal time period for abortion. To base abortion on the nature of prenatal human life means nothing more than to orient oneself to an abstract concept. Ethical values reflect basic life interests of the human society and are historical products and not the kind of generalities which lend themselves to eternal perpetuation. PMID:7281787

    2005-01-01

    The ordinary-language concept of values has a complex history in psychology and in science generally. The traditional fact-value distinction commonly found in traditional scientific perspectives has been challenged by the varieties of philosophical pragmatism, which have similarities to Skinner's radical behaviorism. Skinner's challenge to the fact-value distinction maintained that the phenomena of both "facts" and "values" are a matter of contingencies of environment-behavior interaction, and both phenomena may be observed when a scientist does research or makes recommendations in applied settings based on that research. Some of the processes and variables relevant to an analysis of values as behavioral phenomena are described, and examples of both nonverbal and verbal contingencies are considered, along with implications for the values of an individual and a culture. If the various issues of methodology can be addressed successfully, then behavior analysis will be in the position to move beyond descriptive studies of values, such as those found in humanistic psychology, by providing analyses of the variables of which values are a function.

  8. The origin of cellular life

    NASA Technical Reports Server (NTRS)

    Ingber, D. E.

    2000-01-01

    This essay presents a scenario of the origin of life that is based on analysis of biological architecture and mechanical design at the microstructural level. My thesis is that the same architectural and energetic constraints that shape cells today also guided the evolution of the first cells and that the molecular scaffolds that support solid-phase biochemistry in modern cells represent living microfossils of past life forms. This concept emerged from the discovery that cells mechanically stabilize themselves using tensegrity architecture and that these same building rules guide hierarchical self-assembly at all size scales (Sci. Amer 278:48-57;1998). When combined with other fundamental design principles (e.g., energy minimization, topological constraints, structural hierarchies, autocatalytic sets, solid-state biochemistry), tensegrity provides a physical basis to explain how atomic and molecular elements progressively self-assembled to create hierarchical structures with increasingly complex functions, including living cells that can self-reproduce.

    Available disease-specific questionnaires like the Acromegaly Quality of Life questionnaire have confirmed that quality of life (QoL) is impaired in acromegaly, especially in active disease. Successful therapy improves QoL, but it may not normalize completely even after endocrine cure; furthermore, there is not always a correlation between growth hormone (GH) and insulin-like growth factor 1 and subjective health perception of QoL. Appearance is the dimension most affected and has the highest impact on the patient's QoL. Worse QoL is associated with the presence of musculoskeletal pain, headache (if only medical therapy, not surgery, has been provided), having required treatment with radiotherapy, being older, of female gender, with a longer disease duration, coexisting diabetes mellitus, a higher BMI or becoming GH deficient after treatment for acromegaly.

    2003-01-01

    This is an essay in the history of observation of the natural and social worlds. It explores how nineteenth-century Paris became a field and object of scientific observation and how the everyday lives, and even the health, of scientists living in the city and leaving the city for the "country" modeled observations and theoretical interpretation. The story concerns the first important work in the research school of Louis Pasteur to focus on a human and urban disease, diphtheria, rather than animal and rural ones. An urban field practice emerged from characteristically Parisian forms and literary fictions of street life and public space, leisure, spectacle, and crowds. Some of these, such as transcience, were (and still are) viewed as not only characteristic of "modern life," but also the source of new practices and sensibilities in painting and literature. Microbiological studies elsewhere --such as in New York and Hamburg--were based on very different urban structures, patterns of everyday life, national cultures, and aspects of modernity.

    2003-06-01

    Effective design reuse in electronic products has the potential to provide very large cost savings, substantial time-to-market reduction, and extra sources of revenue. Unfortunately, critical reuse opportunities are often missed because, although they provide clear value to the corporation, they may not benefit the business performance of an internal organization. It is therefore crucial to provide tools to help reuse partners participate in a reuse transaction when the transaction provides value to the corporation as a whole. Value-based Reuse Management (VRM) addresses this challenge by (a) ensuring that all parties can quickly assess the business performance impact of a reuse opportunity, and (b) encouraging high-value reuse opportunities by supplying value-based rewards to potential parties. In this paper we introduce the Value-Based Reuse Management approach and we describe key results on electronic designs that demonstrate its advantages. Our results indicate that Value-Based Reuse Management has the potential to significantly increase the success probability of high-value electronic design reuse.

    In recent decades, a profound conceptual transformation has occurred comprising different areas of biological research, leading to a novel understanding of life processes as much more dynamic and changeable. Discoveries in plants and animals, as well as novel experimental approaches, have prompted the research community to reconsider established concepts and paradigms. This development was taken as an incentive to organise a workshop in May 2014 at the Academia Nazionale dei Lincei in Rome. There, experts on epigenetics, regeneration, neuroplasticity, and computational biology, using different animal and plant models, presented their insights on important aspects of a dynamic architecture of life, which comprises all organisational levels of the organism. Their work demonstrates that a dynamic nature of life persists during the entire existence of the organism and permits animals and plants not only to fine-tune their response to particular environmental demands during development, but underlies their continuous capacity to do so. Here, a synthesis of the different findings and their relevance for biological thinking is presented. PMID:26949518

    Sometimes, conditions of critically ill patients unable to communicate, force us to decide whether or not to continue treatment. The most frequent elements we have to consider in individual patients, are survival at any cost and reduced future physical functioning and quality of life. In this article, we highlight existing literature's inability to precisely determine a given patient's preferences or to guess what they might be. Confronted with this crucial decision, the intensivist must therefore avoid the misstep of imposing their own values and expectations upon the patients. Patients even when unable to communicate must remain the master of their own destiny through their health care surrogate. If the question of their values and expectations, their advanced directives or their health care surrogate have been addressed or evoked beforehand by the family doctor, the chosen treatment modalities taken by the parties involved at a critical moment will thus allow the patient to remain the main actor of his care and destiny.

  2. Arginine, scurvy and Cartier's "tree of life"

    PubMed Central

    2009-01-01

    Several conifers have been considered as candidates for "Annedda", which was the source for a miraculous cure for scurvy in Jacques Cartier's critically ill crew in 1536. Vitamin C was responsible for the cure of scurvy and was obtained as an Iroquois decoction from the bark and leaves from this "tree of life", now commonly referred to as arborvitae. Based on seasonal and diurnal amino acid analyses of candidate "trees of life", high levels of arginine, proline, and guanidino compounds were also probably present in decoctions prepared in the severe winter. The semi-essential arginine, proline and all the essential amino acids, would have provided additional nutritional benefits for the rapid recovery from scurvy by vitamin C when food supply was limited. The value of arginine, especially in the recovery of the critically ill sailors, is postulated as a source of nitric oxide, and the arginine-derived guanidino compounds as controlling factors for the activities of different nitric oxide synthases. This review provides further insights into the use of the candidate "trees of life" by indigenous peoples in eastern Canada. It raises hypotheses on the nutritional and synergistic roles of arginine, its metabolites, and other biofactors complementing the role of vitamin C especially in treating Cartier's critically ill sailors.

    A methodology for deriving a first order dollar value estimate for advanced solar cells which consists of defining scenarios for solar array production and launch to orbit and the associated costs for typical spacecraft, determining that portion affected by cell design and performance and determining the attributable cost differences is presented. Break even values are calculated for a variety of cells; confirming that efficiency and related effects of radiation resistance and temperature coefficient are major factors; array tare mass, packaging and packing factor are important; but cell mass is of lesser significance. Associated dollar values provide a means of comparison.

  4. Derivation of the extrinsic values of biological diversity from its intrinsic value and of both from the first principles of evolution.

    PubMed

    White, Peter S

    2013-12-01

    Conservation ethics have been based on 2 philosophical value systems: extrinsic value (defined broadly to include all values that derive from something external to the thing valued) and intrinsic value. Valuing biological diversity on the basis of an extrinsic value system is problematic because measurement is often difficult; extrinsic value changes as spatial or temporal scales change; extrinsic value differs on the basis of external factors; some species have trivial or negative extrinsic values; and extrinsic value varies across human cultures and societies and with such factors as socioeconomic conditions, individual experiences, and educational backgrounds. Valuing biological diversity on the basis of an intrinsic value system also poses challenges because intrinsic value can be seen as a disguised form of human extrinsic value; intrinsic value is initially ambiguous as to which objects or characteristics of biological diversity are to being valued; all aspects of biological diversity (e.g., species and ecosystems) are transitory; species and ecosystems are not static concrete entities; and intrinsic value of one species is often in conflict with the intrinsic value of other species. Extrinsic and intrinsic value systems share a common origin, such that extrinsic values are always derived from intrinsic value and life mutely expresses both intrinsic and extrinsic values-these are derived from and are products of biological evolution. Probing the values that underlie conservation helps the community clearly articulate its aims.

    Seemingly intangible ecosystem characteristics that preoccupy ecologists, like ecosystem stability and the responsiveness of populations to environmental variation, have quantifiable economic values. We show how to derive these values, and how their consideration should change environmental decision making. To illustrate these concepts, we use a simple reserve design model. When resource managers choose a particular landscape configuration, their decision affects both the mean abundance of species and the temporal variation in abundances. Population stability and related phenomena have economic value, because management actions affect the variance of ecosystem components. In our example, a larger reserve size is recommended when accounting for the stability of the managed ecosystem. PMID:12777632

  6. Optimistic biases in observational learning of value.

    PubMed

    Nicolle, A; Symmonds, M; Dolan, R J

    2011-06-01

    Action-outcome contingencies can be learnt either by active trial-and-error, or vicariously, by observing the outcomes of actions performed by others. The extant literature is ambiguous as to which of these modes of learning is more effective, as controlled comparisons of operant and observational learning are rare. Here, we contrasted human operant and observational value learning, assessing implicit and explicit measures of learning from positive and negative reinforcement. Compared to direct operant learning, we show observational learning is associated with an optimistic over-valuation of low-value options, a pattern apparent both in participants' choice preferences and their explicit post-hoc estimates of value. Learning of higher value options showed no such bias. We suggest that such a bias can be explained as a tendency for optimistic underestimation of the chance of experiencing negative events, an optimism repressed when information is gathered through direct operant learning.

  7. Value of the energy data base

    King, D.W.; Griffiths, J.M.; Roderer, N.K.; Wiederkehr, R.R.V.

    1982-03-31

    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.

  8. The remarkable life of Erwin Schrdinger's What Is Life?

    2015-01-01

    In the seven decades since Schrdinger's book was published, it has gone through stages of differing appraisal, starting with guarded approbation in the 1940s. When several luminaries in molecular biology described the work as influencing their careers, the book's renown increased. In What Is Life?, Schrdinger examined genetics from the perspective of a theoretical physicist, and conjured up ideas that dilettantes admired and experts slighted. Schrdinger sowed his most important ideas in terms of metaphors, allowing readers considerable latitude for interpretation. Some found nothing worthwhile in the book, only chemical naivete and ignorance of work that had already been done. Others found deep inspiration and a desire to understand biological reproduction, even if it required new paradigms of physical science. What Is Life?--like the ancient parable of the blind men and an elephant--is an example of the ineffable nature of truth, pitting subjective experience against the totality of the reality. The legacy of What Is Life? may ultimately be respect for different opinions. PMID:26665967

  11. The conception of life in synthetic biology.

    Deplazes-Zemp, Anna

    2012-12-01

    The phrase 'synthetic biology' is used to describe a set of different scientific and technological disciplines, which share the objective to design and produce new life forms. This essay addresses the following questions: What conception of life stands behind this ambitious objective? In what relation does this conception of life stand to that of traditional biology and biotechnology? And, could such a conception of life raise ethical concerns? Three different observations that provide useful indications for the conception of life in synthetic biology will be discussed in detail: 1. Synthetic biologists focus on different features of living organisms in order to design new life forms, 2. Synthetic biologists want to contribute to the understanding of life, and 3. Synthetic biologists want to modify life through a rational design, which implies the notions of utilising, minimising/optimising, varying and overcoming life. These observations indicate a tight connection between science and technology, a focus on selected aspects of life, a production-oriented approach to life, and a design-oriented understanding of life. It will be argued that through this conception of life synthetic biologists present life in a different light. This conception of life will be illustrated by the metaphor of a toolbox. According to the notion of life as a toolbox, the different features of living organisms are perceived as various rationally designed instruments that can be used for the production of the living organism itself or secondary products made by the organism. According to certain ethical positions this conception of life might raise ethical concerns related to the status of the organism, the motives of the scientists and the role of technology in our society.

    We determined the value of Cs-137 compared to Co-60 as a source for the irradiation of fruit (apples and cherries), pork and medical supplies. Cs-137, in the WESF capsule form, had a value of approximately $0.40/Ci as a substitute for Co-60 priced at approximately $1.00/Ci. The comparison was based on the available curies emitted from the surface of each capsule. We developed preliminary designs for fourteen irradiation facilities; seven were based on Co-60 and seven were based on Cs-137. These designs provided the basis for estimating capital and operating costs which, in turn, provided the basis for determining the value of Cs-137 relative to Co-60 in these applications. We evaluated the effect of the size of the irradiation facility on the value of Cs-137. The cost of irradiation is low compared to the value of the product. Irradiation of apples for disinfestation costs $.01 to .02 per pound. Irradiation for trichina-safe pork costs $.02 per pound. Irradiation of medical supplies for sterilization costs $.07 to .12 per pound. The cost of the irradiation source, either Co-60 or Cs-137, contributed only a minor amount to the total cost of irradiation, about 5% for the fruit and hog cases and about 20% for the medical supply cases. We analyzed the sensitivity of the irradiation costs and Cs-137 value to several key assumptions.

    Submarine hydrothermal vents above serpentinite produce chemical potential gradients of aqueous and ionic hydrogen, thus providing a very attractive venue for the origin of life. This environment was most favourable before Earth's massive CO2 atmosphere was subducted into the mantle, which occurred tens to approximately 100 Myr after the moon-forming impact; thermophile to clement conditions persisted for several million years while atmospheric pCO2 dropped from approximately 25 bar to below 1 bar. The ocean was weakly acid (pH ∼ 6), and a large pH gradient existed for nascent life with pH 9–11 fluids venting from serpentinite on the seafloor. Total CO2 in water was significant so the vent environment was not carbon limited. Biologically important phosphate and Fe(II) were somewhat soluble during this period, which occurred well before the earliest record of preserved surface rocks approximately 3.8 billion years ago (Ga) when photosynthetic life teemed on the Earth and the oceanic pH was the modern value of approximately 8. Serpentinite existed by 3.9 Ga, but older rocks that might retain evidence of its presence have not been found. Earth's sequesters extensive evidence of Archaean and younger subducted biological material, but has yet to be exploited for the Hadean record. PMID:21930576

    Nutraceuticals are important natural bioactive compounds that confer health-promoting and medical benefits to humans. Globally growing demands for value-added nutraceuticals for prevention and treatment of human diseases have rendered nutraceuticals a multi-billion dollar market. However, supply limitations and extraction difficulties from natural sources such as plants, animals or fungi, restrict the large-scale use of nutraceuticals. Metabolic engineering via microbial production platforms has been advanced as an eco-friendly alternative approach for production of value-added nutraceuticals from simple carbon sources. Microbial platforms like the most widely used Escherichia coli and Saccharomyces cerevisiae have been engineered as versatile cell factories for production of diverse and complex value-added chemicals such as phytochemicals, prebiotics, polysaccaharides and poly amino acids. This review highlights the recent progresses in biological production of value-added nutraceuticals via metabolic engineering approaches. PMID:26716360

    The relative merits of molecular and paleontological dates of major branching points in the tree of life are currently debated. In some cases, molecular date estimates are up to twice as old as paleontological dates. However, although it is true that paleontological dates are often too young (missing fossils), molecular dates are often too old (statistical bias). Intense study of the dating of major splits in the tree of mammals has shown rapprochement as fossil dates become older and molecular dates become younger. PMID:12805535

    1993-01-01

    In "From Value Chain to Value Constellation: Designing Interactive Strategy" (July-August 1993), Richard Normann and Rafael Ramírez argue that successful companies increasingly do not just add value, they reinvent it. The key strategic task is to reconfigure roles and relationships among a constellation of actors--suppliers, business partners, customers--in order to mobilize the creation of value in new forms and by new players. What is so different about this new logic of value? It breaks down the distinction between products and services and combines them into activity-based "offerings" from which customers can create value for themselves. But as potential offerings become more complex, so do the relationships necessary to create them. As a result, a company's strategic task becomes the reconfiguration and integration of its compentencies and customers. Normann and Ramírez provide three illustrations of these new rules of strategy. IKEA has blossomed into the world's largest retailer of home furnishings by redefining the relationships and organizational pratices of the furniture business. Danish pharmacies and their national organization have used the opportunity of health care reform to reconfigure their relationships with customers, doctors, hospitals, drug manufacturers, and with Danish and international health organizations.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:10129057

    2006-06-01

    Bootstrap Analysis is a common tool in cladistics, and consequently many authors tend to believe that it could be close to a test of monophyly. In fact, it is only a procedure to calculate the redundancy of a certain character pattern among taxa. To demonstrate this, we set up a study with questionable data: Four skulls of great apes and humans were digitally photographed, and the pixels' brightness values were simply transformed to a one-zero-matrix, which was then used to calculate a Wagner tree with PHYLIP. As a rule, the higher the resolution of the photos is, the higher are the bootstrap values of supported taxa (and the lower are the bootstrap values of non-supported data). Redundancy of intertaxic information might indeed be an indicator of phylogenetic relationship, but can also be due to other reasons, like functional-adaptive needs in morphology, or semantic needs in a DNA-code. As a result, we tend to believe that high bootstrap values are actually less important than low ones. It is safer, based on a low bootstrap value, to claim that a certain taxon is not well supported by certain data. Therefore, we recommend discussions of low bootstrap values in future publications.

    The main aim of every aesthetic surgery is to offer patients a subjective benefit. Today, the construct "health-related quality of life" (HRQOL) is considered one of the most important parameters in the evaluation of treatment. Several recent studies using validated tools to measure HRQOL show that otoplasty leads to a significant and long-lasting increase in the HRQOL of children and adults suffering from protruding ears. However, irreversible auricular deformities after failed otoplasty can be more emotionally draining for the patient than the preoperative state. The respective risk is higher when using cartilage rasping or cutting techniques compared with pure suture techniques. PMID:25527381

    Previous work has identified a distributed network of neural systems involved in appraising the value of rewards, such as when winning $100 versus $1. These studies, however, confounded monetary value and the number used to represent it, which leads to the possibility that some elements in the network may be specialized for processing numeric rather than monetary value. To test this hypothesis, we manipulated numeric magnitude and units to construct a range of economic rewards for simple decisions (e.g., 1, $1, 100, $100). Consistent with previous research in numerical cognition, results showed that blood-oxygen-level-dependent (BOLD) activity in intraparietal sulcus was correlated with changes in numeric magnitude, independent of monetary value, whereas activity in orbitofrontal cortex was correlated with monetary value, independent of numeric magnitude. Finally, region-of-interest analyses revealed that the BOLD response to numeric magnitude, but not monetary value, described a compressive function. Together, these findings highlight the importance of numerical cognition for understanding how the brain processes monetary rewards. PMID:24958687

    Abstract This paper discusses how we intend to take forward the vision of a Bibliography of Life in the ViBRANT project. The underlying principle of the Bibliography is to provide taxonomists and others with a freely accessible bibliography covering the whole of life. Such a bibliography has been achieved for specific study areas within taxonomy, but not for “life” as a whole. The creation of such a comprehensive tool has been hindered by various social and technical issues. The social concerns focus on the willingness of users to contribute to the Bibliography. The technical concerns relate to the architecture required to deliver the Bibliography. These issues are discussed in the paper and approaches to addressing them within the ViBRANT project are described, to demonstrate how we can now seriously consider building a Bibliography of Life. We are particularly interested in the potential of the resulting tool to improve the quality of bibliographic references. Through analysing the large number of references in the Bibliography we will be able to add metadata by resolving known issues such as geographical name variations. This should result in a tool that will assist taxonomists in two ways. Firstly, it will be easier for them to discover relevant literature, especially pre-digital literature; and secondly, it will be easier for them to identify the canonical form for a citation The paper also covers related issues relevant to building the tool in ViBRANT, including implementation and copyright, with suggestions as to how we could address them.

    The mosquito parasite, Coelomomyces psorophorae (Blastocladiales, Chytridiomycetes) alternates obligately between the larvae of Culiseta inornata and the copepod Cyclops vernalis. Isogametes, derived from heterothallic, wall-less gametangia which develop in the copepod, fuse to produce a diploid zygote that subsequently infects the mosquito host. Zoospores from the resistant sporangia which are produced in the haemocoel of the mosquito infect the copepod. A tentative life-history is proposed and implications of these discoveries for the biology, taxonomy, and possible role of Coelomomyces in biological control are discussed. Images PMID:235761

    Health and disease can only be distinguished by accurate and reliable reference values of a particular laboratory test. It is now a proven fact that there is considerable variation in hematology reference intervals depending on the demographic and preanalytical variables. There are evidences that values provided by manufacturers do not have appropriate application for all populations. Moreover, reference ranges provided by different laboratory manuals and books also do not solve this problem. We are presenting here normal reference ranges of Malaysian population. These values were determined by using Sysmex XE-2100 and ACL 9000 hematology and coagulation analyzers. Results from this study showed that there were considerable differences in the reference values from manufacturers, western population or laboratory manuals compared with those from the local population.

    A considerable amount of uncertainty surrounds the length of human life. The standard deviation in adult life span is about 15 years in the U.S., and theory and evidence suggest it is costly. I calibrate a utility-theoretic model of preferences over length of life and show that one fewer year in standard deviation is worth about half a mean life year. Differences in the standard deviation exacerbate cross-sectional differences in life expectancy between the U.S. and other industrialized countries, between rich and poor countries, and among poor countries. Accounting for the cost of life-span variance also appears to amplify recently discovered patterns of convergence in world average human well-being. This is partly for methodological reasons and partly because unconditional variance in human length of life, primarily the component due to infant mortality, has exhibited even more convergence than life expectancy.

    The current research aimed to address the inconsistent findings regarding cultural differences in attitudes toward older adults by differentiating the effects of personal and cultural values. In Study 1, we used data from the sixth wave of the World Values Survey to examine attitudes toward older adults across cultures, and how different personal values (i.e., communal vs. agentic) and cultural values (i.e., individualism) predicted these attitudes. The results of hierarchical linear modeling analyses showed that after controlling for potential covariates, personal communal values positively correlated with positive attitudes toward older adults; however, cultural individualistic values did not. To further examine the causal effects of personal values (vs. cultural values), we conducted an experimental study and confirmed that priming personal values rather than cultural values had significant effects on ageism attitudes. The present studies help to reconcile conflicting results on cultural differences in attitudes toward older adults. (PsycINFO Database Record PMID:26691301

    A life cycle assessment has been done to compare the potential environmental impacts of various gasoline blends that meet octane and vapor pressure specifications. The main blending components of alkylate, cracked gasoline, and reformate have different octane and vapor pressure values as well as different potential environmental impacts. Because the octane and vapor pressure values are nonlinearly related to impacts, the results of this study show that some blends are better for the environment than others. To determine blending component compositions, simulations of a reformer were done at various operating conditions. The reformate products of these simulations had a wide range of octane values and potential environmental impacts. Results of the study indicate that for low-octane gasoline (95 Research Octane Number), lower reformer temperatures and pressures generally decrease the potential environmental impacts. However, different results are obtained for high-octane gasoline (98 RON), where increasing reformer temperatures and pressures increase the reformate octane values faster than the potential environmental impacts. The higher octane values for reformate allow blends to have less reformate, and therefore high-octane gasoline can have lower potential environmental impacts when the reformer is operated at higher temperatures and pressures. In the blends studied, reformate and cracked gasoline have the highest total impacts, of which photochemical ozone creation is the largest contributor (assuming all impact categories are equally weighted). Alkylate has a much lower total potential environmental impact but does have higher impact values for human toxicity by ingestion, aquatic toxicity, terrestrial toxicity, and acidification. Therefore, depending on environmental priorities, different gasoline blends and operating conditions should be chosen to meet octane and vapor pressure specifications. PMID:12953887

    U.S. regulations require offsets for aquatic ecosystems damaged during land development, often through restoration of alternative resources. What effect does large-scale wetland and stream restoration have on surrounding land values? Restoration effects on real estate values have substantial implications for protecting resources, increasing tax base, and improving environmental policies. Our analysis focuses on the three-county Raleigh-Durham-Chapel Hill, North Carolina region, which has experienced rapid development and extensive aquatic ecological restoration (through the state's Ecosystem Enhancement Program [EEP]). Since restoration sites are not randomly distributed across space, we used a genetic algorithm to match parcels near restoration sites with comparable control parcels. Similar to propensity score analysis, this technique facilitates statistical comparison and isolates the effects of restoration sites on surrounding real estate values. Compared to parcels not proximate to any aquatic resources, we find that, 1) natural aquatic systems steadily and significantly increase parcel values up to 0.75 mi away, and 2) parcels <0.5 mi from EEP restoration sites have significantly lower sale prices, while 3) parcels >0.5 mi from EEP sites gain substantial amenity value. When we control for intervening water bodies (e.g. un-restored streams and wetlands), we find a similar inflection point whereby parcels <0.5 mi from EEP sites exhibit lower values, and sites 0.5-0.75 mi away exhibit increased values. Our work points to the need for higher public visibility of aquatic ecosystem restoration programs and increased public information about their value. PMID:23792789

  4. Obesity, longevity, quality of life

    PubMed Central

    2010-01-01

    Previous investigations demonstrated that optimization of murine immunological reactivity in tissue culture required a sulfhydryl compound; the most effective being 2-mercaptoethanol (2-Me). Since these reports, 2-Me was found beneficial for both growth/function of other cell-types in vitro, including those of other species, and when fed orally, it impeded and/or reversed some in situ physiological changes associated with aging. More recently, thiol-containing compounds possessing oxidation-reduction potentials weaker than 2-Me were found to impart beneficial effects for many other, including human, diseases. Based on these effects, the research herein addressed the question: What consequences might dietary 2-Me impart on health and disease of mice other than those associated with aging? The main parameters monitored over the lifetime of individual animals exposed to dietary 10−3 M 2-Me in their drinking water were: quality of life (obesity and development of recumbent, emaciated and/or cachectic health, longevity, and appearance of tumors. Instead of anticipated toxic attributes, the following unique benefits were found: mean survival of a moderately-lived strain (A/J) was increased 40.8%, high-fat-diet obesity was curtailed in C57BL/10 mice, and a goal of aging intervention protocols, namely preventing loss of quality of life during aging (recumbent, emaciated and/or cachectic) was achieved.

It is well known that the current environment of an individual can affect body weight, however, growing evidence suggests that the environment in very early life may be particularly important in determining long term obesity risk. This was prompted by a series of epidemiological studies demonstrating a relationship between suboptimal early growth and later risk of obesity. Evidence from human studies as well as animal models have shown that alterations in nutrition and growth in utero and during early postnatal life can have permanent effects on systems mediating regulation of energy balance. Rapid postnatal growth in particular has been associated with increased risk of developing obesity while slower postnatal growth lowers this risk. Alterations in pathways mediating energy homeostasis have been associated with both patterns of early growth. These include changes in structure and function of neuronal pathways in the brain which lead to deregulation of pathways mediating energy balance. In addition to the alterations at the central level, early nutrition can have detrimental long-lasting effects on peripheral physiological systems, for example the storage of fat and utilization of nutrients that make an individual more prone to development of obesity. The fundamental mechanisms underlying these programmed changes are still to be fully defined, although epigenetic mechanisms may play an important role. PMID:23749690

  6. Importance of life cycle assessment

    Bridges, J.S.

    1994-06-16

    The paper presents Life Cycle Assessment (LCA) as a tool to assist the waste professional with integrated waste management. LCA can be the connection between the waste professional and designer/producer to permit the waste professional to encourage the design of products so material recovery is most efficient and markets can be better predicted. The waste professional can better monitor the involvement of the consumer in waste management by using LCA and looking upstream at how the consumer actually reacts to products and packaging. LCA can also help the waste professional better understand the waste stream.

  8. Rock Surfaces as Life Indicators: New Ways to Demonstrate Life and Traces of Former Life

    Life and its former traces can only be detected from space when they are abundant and exposed to the planetary atmosphere at the moment of investigation by orbiters. Exposed rock surfaces present a multifractal labyrinth of niches for microbial life. Based upon our studies of highly stress-resistant microcolonial fungi of stone monument and desert rock surfaces, we propose that microbial biofilms that develop and become preserved on rock surfaces can be identified remotely by the following characteristics: (1) the existence of spectroscopically identifiable compounds that display unique adsorption, diffraction, and reflection patterns characteristic of biogenerated organic compounds (e.g., chlorophylls, carotenes, melanins, and possibly mycosporines), (2) demonstrably biogenic geomorphological features (e.g., biopitting, biochipping, and bioexfoliation), and (3) biominerals produced in association with biofilms that occupy rock surfaces (e.g., oxalates, forsterite, and special types of carbonates, sulfides, and silicates). Such traces or biosignatures of former life could provide macroscopically visible morphotypes and chemically identifiable products uniquely indicative of life.

    Understanding the origin of cellular life on Earth requires the discovery of plausible pathways for the transition from complex prebiotic chemistry to simple biology, defined as the emergence of chemical assemblies capable of Darwinian evolution. We have proposed that a simple primitive cell, or protocell, would consist of two key components: a protocell membrane that defines a spatially localized compartment, and an informational polymer that allows for the replication and inheritance of functional information. Recent studies of vesicles composed of fatty-acid membranes have shed considerable light on pathways for protocell growth and division, as well as means by which protocells could take up nutrients from their environment. Additional work with genetic polymers has provided insight into the potential for chemical genome replication and compatibility with membrane encapsulation. The integration of a dynamic fatty-acid compartment with robust, generalized genetic polymer replication would yield a laboratory model of a protocell with the potential for classical Darwinian biological evolution, and may help to evaluate potential pathways for the emergence of life on the early Earth. Here we discuss efforts to devise such an integrated protocell model. PMID:20484387

  11. Human Value, Dignity, and the Presence of Others.

    In the health care professions, the meaning of--and implications for--'dignity' and 'value' are progressively more important, as scholars and practitioners increasingly have to make value judgments when making care decisions. This paper looks at the various arguments for competing sources of human value that medical professionals can consider--human rights, autonomy, and a higher-order moral value--and settles upon a foundational model that is related to (though distinct from) the Kantian model that is popular within the medical community: human value is foundational; human dignity, autonomy, and rights derive from the relational quality of human dignity. Moral dignity is expressed though the relationships we cultivate, the communal ends we pursue, and the rights we enjoy. Correlatively, human dignity is inseparable from its ground (i.e., morality), and the relationship between these two is best represented for Kant in the humanities formulation. The foundational model of dignity ensures that human value is non-circularly derived, but is ultimately tied to expressions of individual human dignity that comes from the dignity of morality. Linking Kant's dignity of humanity to the dignity of morality affords a unique and efficacious response to the discussion of human value. In one sense, dignity is amplificatory, since its worth is inextricable with that of autonomy and the rights afforded to the autonomous. But that isn't to say that the worth of dignity is merely amplificatory. Rather, human dignity indicates the absolute inner value (MM 6:435) found in each individual in virtue of being human (MM 6:435, 462). That inner worth engenders certain universal rights--derivable from the dignity and fundamental rational appeal of morality--just as it provides for the possibility for a community of beings to seek to live the moral life.

  12. A Rooted Net of Life

    PubMed Central

    2011-01-01

    Abstract Phylogenetic reconstruction using DNA and protein sequences has allowed the reconstruction of evolutionary histories encompassing all life. We present and discuss a means to incorporate much of this rich narrative into a single model that acknowledges the discrete evolutionary units that constitute the organism. Briefly, this Rooted Net of Life genome phylogeny is constructed around an initial, well resolved and rooted tree scaffold inferred from a supermatrix of combined ribosomal genes. Extant sampled ribosomes form the leaves of the tree scaffold. These leaves, but not necessarily the deeper parts of the scaffold, can be considered to represent a genome or pan-genome, and to be associated with members of other gene families within that sequenced (pan)genome. Unrooted phylogenies of gene families containing four or more members are reconstructed and superimposed over the scaffold. Initially, reticulations are formed where incongruities between topologies exist. Given sufficient evidence, edges may then be differentiated as those representing vertical lines of inheritance within lineages and those representing horizontal genetic transfers or endosymbioses between lineages.

    Background: Opposing groups of scientists have recently engaged in a heated dispute over a preliminary European Commission (EC) report on its regulatory policy for endocrine-disrupting chemicals. In addition to the scientific issues at stake, a central question has been how scientists can maintain their objectivity when informing policy makers. Objectives: Drawing from current ethical, conceptual, and empirical studies of objectivity and conflicts of interest in scientific research, we propose guiding principles for communicating scientific findings in a manner that promotes objectivity, public trust, and policy relevance. Discussion: Both conceptual and empirical studies of scientific reasoning have shown that it is unrealistic to prevent policy-relevant scientific research from being influenced by value judgments. Conceptually, the current dispute over the EC report illustrates how scientists are forced to make value judgments about appropriate standards of evidence when informing public policy. Empirical studies provide further evidence that scientists are unavoidably influenced by a variety of potentially subconscious financial, social, political, and personal interests and values. Conclusions: When scientific evidence is inconclusive and major regulatory decisions are at stake, it is unrealistic to think that values can be excluded from scientific reasoning. Thus, efforts to suppress or hide interests or values may actually damage scientific objectivity and public trust, whereas a willingness to bring implicit interests and values into the open may be the best path to promoting good science and policy.

    The investigation of biological systems highly depends on the possibilities that allow scientists to visualize and quantify biomolecules and their related activities in real-time and non-invasively. G-protein coupled receptors represent a family of very dynamic and highly regulated transmembrane proteins that are involved in various important physiological processes. Since their localization is not confined to the cell surface they have been a very attractive "moving target" and the understanding of their intracellular pathways as well as the identified protein-protein-interactions has had implications for therapeutic interventions. Recent and ongoing advances in both the establishment of a variety of labeling methods and the improvement of measuring and analyzing instrumentation, have made fluorescence techniques to an indispensable tool for GPCR imaging. The illumination of their complex life cycle, which includes receptor biosynthesis, membrane targeting, ligand binding, signaling, internalization, recycling and degradation, will provide new insights into the relationship between spatial receptor distribution and function. This review covers the existing technologies to track GPCRs in living cells. Fluorescent ligands, antibodies, auto-fluorescent proteins as well as the evolving technologies for chemical labeling with peptide- and protein-tags are described and their major applications concerning the GPCR life cycle are presented.

  15. Early Life Nutrition, Epigenetics and Programming of Later Life Disease

    The global pandemic of obesity and type 2 diabetes is often causally linked to marked changes in diet and lifestyle; namely marked increases in dietary intakes of high energy diets and concomitant reductions in physical activity levels. However, less attention has been paid to the role of developmental plasticity and alterations in phenotypic outcomes resulting from altered environmental conditions during the early life period. Human and experimental animal studies have highlighted the link between alterations in the early life environment and increased risk of obesity and metabolic disorders in later life. This link is conceptualised as the developmental programming hypothesis whereby environmental influences during critical periods of developmental plasticity can elicit lifelong effects on the health and well-being of the offspring. In particular, the nutritional environment in which the fetus or infant develops influences the risk of metabolic disorders in offspring. The late onset of such diseases in response to earlier transient experiences has led to the suggestion that developmental programming may have an epigenetic component, as epigenetic marks such as DNA methylation or histone tail modifications could provide a persistent memory of earlier nutritional states. Moreover, evidence exists, at least from animal models, that such epigenetic programming should be viewed as a transgenerational phenomenon. However, the mechanisms by which early environmental insults can have long-term effects on offspring are relatively unclear. Thus far, these mechanisms include permanent structural changes to the organ caused by suboptimal levels of an important factor during a critical developmental period, changes in gene expression caused by epigenetic modifications (including DNA methylation, histone modification, and microRNA) and permanent changes in cellular ageing. A better understanding of the epigenetic basis of developmental programming and how these effects may be transmitted across generations is essential for the implementation of initiatives aimed at curbing the current obesity and diabetes crisis.

    This study estimated the value of solar thermal-generated industrial process heat (IPH) as a function of process heat temperature. The value of solar thermal energy is equal to the cost of producing energy from conventional fuels and equipment if the energy produced from either source provides an equal level of service. This requirement put the focus of this study on defining and characterizing conventional process heat equipment and fuels. Costs (values) were estimated for 17 different design points representing different combinations of conventional technologies, temperatures, and fuels. Costs were first estimated for median or representative conditions at each design point. The cost impact of capacity factor, efficiency, fuel escalation rate, and regional fuel price differences were then evaluated by varying each of these factors within credible ranges.

    Methods of construction and required metrologic properties of quality of life scales are reviewed while looking for such tools in the field of urinary tract infections. To capture the subjectivity of patients, to reach a simple measure scale, to build a reliable tool, are conflicting aims. Although they appeared several years ago and are broadly spread in all medical fields, including urology, quality of life scales are still in early ages and are not always widely admitted. Quality of life scales can be criticized, but they capture specific data and are very useful in some fields. Today, there are no quality of life scales in the field of urinary infectiology.
