The moral status of extraterrestrial life.

PubMed

Persson, Erik

2012-10-01

If we eventually discover extraterrestrial life, do we have any moral obligations for how to treat the life-forms we find; does it matter whether they are intelligent, sentient, or just microbial-and does it matter that they are extraterrestrial? In this paper, I examine these questions by looking at two of the basic questions in moral philosophy: What does it take to be a moral object? and What has value of what kind? I will start with the first of these questions by looking at the most important attempts to answer this question on our own planet and by asking whether and how they could be applied to extraterrestrial life. The results range from a very strong protection of all extraterrestrial life and all extraterrestrial environments, whether inhabited or not, to total exclusion of extraterrestrial life. Subsequently, I also examine whether extraterrestrial life that lacks moral status can have value to human or alien life with moral status, and if that could generate any obligations for how to treat extraterrestrial life. Based on this analysis, I conclude that extraterrestrial life-forms can have both instrumental value and end value to moral objects, which has strong implications for how to treat them.

An attempt to estimate the economic value of the loss of human life due to landslide and flood events in Italy

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.

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.

Preference elicitation studies reporting societal views on the relative value of end-of-life treatments have produced equivocal results. This paper presents an alternative method, combining Q methodology and survey techniques (Q2S) to determine the distribution of 3 viewpoints on the relative value of end-of-life treatments identified in a previous, published, phase of this work. These were Viewpoint 1, "A population perspective: value for money, no special cases"; Viewpoint 2, "Life is precious: valuing life-extension and patient choice"; and Viewpoint 3, "Valuing wider benefits and opportunity cost: the quality of life and death." A Q2S survey of 4,902 respondents across the United Kingdom measured agreement with these viewpoints; 37% most agreed with Viewpoint 1, 49% with Viewpoint 2, and 9% with Viewpoint 3. Regression analysis showed associations of viewpoints with gender, level of education, religion, voting preferences, and satisfaction with the NHS. The Q2S approach provides a promising means to investigate how in-depth views and opinions are represented in the wider population. As demonstrated in this study, there is often more than 1 viewpoint on a topic and methods that seek to estimate that averages may not provide the best guidance for societal decision-making. © 2018 The Authors.

2015-03-01

The appropriate thresholds for decisions on the cost-effectiveness of medical interventions remain controversial, especially in 'end-of-life' situations. Evidence of the values placed on different types of health gain by the general public is limited. Across nine European countries, 17,657 people were presented with different hypothetical health scenarios each involving a gain of one quality adjusted life year (QALY) and asked about their willingness to pay (WTP) for that gain. The questions included quality of life (QoL) enhancing and life extending health gains, and a scenario where respondents faced imminent, premature death. The mean WTP values for a one-QALY gain composed of QoL improvements were modest (PPP$11,000). When comparing QALY gains obtained in the near future, the valuation of life extension exceeded the valuation of QoL enhancing gains (mean WTP PPP$19,000 for a scenario in which a coma is avoided). The mean WTP values were higher still when respondents faced imminent, premature death (PPP$29,000). Evidence from the largest survey on the value of health gains by the general public indicated a higher value for life extending gains compared with QoL enhancing gains. A further modest premium may be indicated for life extension when facing imminent, premature death. Copyright © 2013 John Wiley & Sons, Ltd.

The comparative effectiveness and cost-effectiveness of vitreoretinal interventions.

PubMed

Brown, Melissa M; Brown, Gary C; Brown, Heidi C; Irwin, Blair; Brown, Kathryn S

2008-05-01

The comparative effectiveness of medical interventions has recently been emphasized in the literature, typically for interventions in a similar class. Value-based medicine, the practice of medicine based on the value (improvement in quality of life and/or length of life) conferred by medical interventions, allows a measure of comparative effectiveness of interventions across all of health care, no matter how disparate. This report discusses recent comparative effectiveness studies in the vitreoretinal literature. Vitreoretinal interventions have good to excellent comparative effectiveness compared with commonly utilized interventions across health care, such as treatment for osteoporosis and hyperlipidemia. They also tend to be cost-effective when an upper limit of $100 000/quality-adjusted life-year is utilized. Value can be measured using either or both of two outcomes - the quality-adjusted life-year gain and/or the percentage improvement in value - both of which allow for an evaluation of comparative effectiveness, which can be compared on the same scale for every intervention. This value can also be integrated with costs using the outcome of dollars expended per quality-adjusted life-year ($/quality-adjusted life-year, or the cost-utility ratio), which allows a comparison of cost-effectiveness across all interventions. The majority of vitreoretinal interventions confer considerable value and are cost-effective.

Precision half-life measurement of 11C: The most precise mirror transition F t value

Background: The precise determination of the F t value in T =1 /2 mixed mirror decays is an important avenue for testing the standard model of the electroweak interaction through the determination of Vu d in nuclear β decays. 11C is an interesting case, as its low mass and small QE C value make it particularly sensitive to violations of the conserved vector current hypothesis. The present dominant source of uncertainty in the 11CF t value is the half-life. Purpose: A high-precision measurement of the 11C half-life was performed, and a new world average half-life was calculated. Method: 11C was created by transfer reactions and separated using the TwinSol facility at the Nuclear Science Laboratory at the University of Notre Dame. It was then implanted into a tantalum foil, and β counting was used to determine the half-life. Results: The new half-life, t1 /2=1220.27 (26 ) s, is consistent with the previous values but significantly more precise. A new world average was calculated, t1/2 world=1220.41 (32 ) s, and a new estimate for the Gamow-Teller to Fermi mixing ratio ρ is presented along with standard model correlation parameters. Conclusions: The new 11C world average half-life allows the calculation of a F tmirror value that is now the most precise value for all superallowed mixed mirror transitions. This gives a strong impetus for an experimental determination of ρ , to allow for the determination of Vu d from this decay.

In recent years, precision measurements have led to considerable advances in several areas of physics, including fundamental symmetry. Precise determination of ft values for superallowed mixed transitions between mirror nuclides could provide an avenue to test the theoretical corrections used to extract the Vud matrix element from superallowed pure Fermi transitions. Calculation of the ft value requires the half-life, branching ratio, and Q value. 25Al decay is of particular interest as its half-life is derived from a series of conflicting measurements, and the largest uncertainty on the ft value stems from the half-life uncertainty. The life-time was determined by the β counting of implanted 25Al on a Ta foil that was removed from the beam for counting. The 25Al beam was produced by a transfer reaction and separated by the TwinSol facility of the Nuclear Science Laboratory of the University of Notre Dame. The 25Al results will be presented with preliminary results of more recent half-life measurements. The National Science Foundation.

Ecology of Floristic Quality Assessment: testing for correlations between coefficients of conservatism, species traits and mycorrhizal responsiveness

PubMed Central

Koziol, Liz; Bever, James D

2018-01-01

Abstract Many plant species are limited to habitats relatively unaffected by anthropogenic disturbance, so protecting these undisturbed habitats is essential for plant conservation. Coefficients of conservatism (C values) were developed as indicators of a species’ sensitivity to anthropogenic disturbance, and these values are used in Floristic Quality Assessment as a means of assessing natural areas and ecological restoration. However, assigning of these values is subjective and improved quantitative validation of C values is needed. We tested whether there are consistent differences in life histories between species with high and low C values. To do this, we grew 54 species of tallgrass prairie plants in a greenhouse and measured traits that are associated with trade-offs on the fast-slow continuum of life-history strategies. We also grew plants with and without mycorrhizal fungi as a test of these species’ reliance on this mutualism. We compared these traits and mycorrhizal responsiveness to C values. We found that six of the nine traits we measured were correlated with C values, and together, traits predicted up to 50 % of the variation in C values. Traits including fast growth rates and greater investment in reproduction were associated with lower C values, and slow growth rates, long-lived leaves and high root:shoot ratios were associated with higher C values. Additionally, plants with high C values and a slow life history were more responsive to mutualisms with mycorrhizal fungi. Overall, our results connect C values with life-history trade-offs, indicating that high C value species tend to share a suite of traits associated with a slow life history. PMID:29383232

Pursuit of communal values in an agentic manner: a way to happiness?

2014-01-01

The present research studies the association between traits, values, and life satisfaction. While values should influence the direction of an individual's goals and behavior, his/her traits impact effort-expenditure, efficiency, and persistence in goal-pursuit. We apply the framework of the "Big Two" of agency and communion (Bakan, 1966) for distinguishing the content of values and traits. While agentic content refers to qualities relevant for goal-attainment, such as assertiveness, competence or persistence, communal content refers to qualities relevant for the establishment and maintenance of social relationships, such as being friendly, helpful, or fair. We predict that high scores on communal values and high scores on agentic traits are associated with life satisfaction. We test these predictions in two studies conducted in different countries (Germany and Russia) with different cultural background. The findings support our reasoning: across both countries we find positive associations of communal values and agentic traits with life satisfaction; and individuals high in communal values and high in agentic traits are most satisfied with their lives. In Russia, the association of communal values with life satisfaction is moderated by agentic traits; in Germany, however, there is a main effect of communal values.

Terms such as sanctity and inviolability have failed to provide a legally coherent or ethically sound principle upon which to determine the scope of the intrinsic value of life against extrinsic , quality-of-life considerations in a medical context . In their recent work , Margaret Brazier and Suzanne Ost introduce a new term , reverence for life, which they suggest may be more appropriate when attempting to navigate the murky waters of the meaning of life and the value that should be attached to it . They suggest that reverence should be utilised as an alternative that better reflects the nuances and the realities of the dilemma . This paper explores the existing difficulties before considering how the principle of reverence might provide a principled compromise over when the presumption in favour of preserving life should be rebutted .

Assessing the quality of life history information in publicly available databases.

Thorson, James T; Cope, Jason M; Patrick, Wesley S

2014-01-01

Single-species life history parameters are central to ecological research and management, including the fields of macro-ecology, fisheries science, and ecosystem modeling. However, there has been little independent evaluation of the precision and accuracy of the life history values in global and publicly available databases. We therefore develop a novel method based on a Bayesian errors-in-variables model that compares database entries with estimates from local experts, and we illustrate this process by assessing the accuracy and precision of entries in FishBase, one of the largest and oldest life history databases. This model distinguishes biases among seven life history parameters, two types of information available in FishBase (i.e., published values and those estimated from other parameters), and two taxa (i.e., bony and cartilaginous fishes) relative to values from regional experts in the United States, while accounting for additional variance caused by sex- and region-specific life history traits. For published values in FishBase, the model identifies a small positive bias in natural mortality and negative bias in maximum age, perhaps caused by unacknowledged mortality caused by fishing. For life history values calculated by FishBase, the model identified large and inconsistent biases. The model also demonstrates greatest precision for body size parameters, decreased precision for values derived from geographically distant populations, and greatest between-sex differences in age at maturity. We recommend that our bias and precision estimates be used in future errors-in-variables models as a prior on measurement errors. This approach is broadly applicable to global databases of life history traits and, if used, will encourage further development and improvements in these databases.

Effect of Roller Geometry on Roller Bearing Load-Life Relation

NASA Technical Reports Server (NTRS)

Oswald, Fred B.; Zaretsky, Erwin V.; Poplawski, Joseph V.

2015-01-01

Cylindrical roller bearings typically employ roller profile modification to equalize load distribution, minimize stress concentration at roller ends and allow for a small amount of misalignment. The 1947 Lundberg-Palmgren analysis reported an inverse fourth power relation between load and life for roller bearings with line contact. In 1952, Lundberg and Palmgren changed their load-life exponent to 10/3 for roller bearings, assuming mixed line and point contact. The effect of roller-crown profile was reanalyzed in this paper to determine the actual load-life relation for modified roller profiles. For uncrowned rollers (line contact), the load-life exponent is p = 4, in agreement with the 1947 Lundberg-Palmgren value but crowning reduces the value of the exponent, p. The lives of modern roller bearings made from vacuum-processed steels significantly exceed those predicted by the Lundberg-Palmgren theory. The Zaretsky rolling-element bearing life model of 1996 produces a load-life exponent of p = 5 for flat rollers, which is more consistent with test data. For the Zaretsky model with fully crowned rollers p = 4.3. For an aerospace profile and chamfered rollers, p = 4.6. Using the 1952 Lundberg-Palmgren value p = 10/3, the value incorporated in ANSI/ABMA and ISO bearing standards, can create significant life calculation errors for roller bearings.

Can broader diffusion of value-based insurance design increase benefits from US health care without increasing costs? Evidence from a computer simulation model.

Evidence suggests that cost sharing (i.e.,copayments and deductibles) decreases health expenditures but also reduces essential care. Value-based insurance design (VBID) has been proposed to encourage essential care while controlling health expenditures. Our objective was to estimate the impact of broader diffusion of VBID on US health care benefits and costs. We used a published computer simulation of costs and life expectancy gains from US health care to estimate the impact of broader diffusion of VBID. Two scenarios were analyzed: (1) applying VBID solely to pharmacy benefits and (2) applying VBID to both pharmacy benefits and other health care services (e.g., devices). We assumed that cost sharing would be eliminated for high-value services (<$100,000 per life-year), would remain unchanged for intermediate- or unknown-value services ($100,000-$300,000 per life-year or unknown), and would be increased for low-value services (>$300,000 per life-year). All costs are provided in 2003 US dollars. Our simulation estimated that approximately 60% of health expenditures in the US are spent on low-value services, 20% are spent on intermediate-value services, and 20% are spent on high-value services. Correspondingly, the vast majority (80%) of health expenditures would have cost sharing that is impacted by VBID. With prevailing patterns of cost sharing, health care conferred 4.70 life-years at a per-capita annual expenditure of US$5,688. Broader diffusion of VBID to pharmaceuticals increased the benefit conferred by health care by 0.03 to 0.05 additional life-years, without increasing costs and without increasing out-of-pocket payments. Broader diffusion of VBID to other health care services could increase the benefit conferred by health care by 0.24 to 0.44 additional life-years, also without increasing costs and without increasing overall out-of-pocket payments. Among those without health insurance, using cost saving from VBID to subsidize insurance coverage would increase the benefit conferred by health care by 1.21 life-years, a 31% increase. Broader diffusion of VBID may amplify benefits from US health care without increasing health expenditures.

The effect of values and culture on life-support decisions.

PubMed Central

Klessig, J

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

Although clergy interact with approximately half of U.S. patients facing end-of-life medical decisions, little is known about clergy-congregant interactions or clergy influence on end-of-life decisions. The objective was to conduct a nationally representative survey of clergy beliefs and practices. A mailed survey to a nationally representative sample of clergy completed in March 2015 with 1005 of 1665 responding (60% response rate). The primary predictor variable was clergy religious values about end-of-life medical decisions, which measured belief in miracles, the sanctity of life, trust in divine control, and redemptive suffering. Outcome variables included clergy-congregant end-of-life medical conversations and congregant receipt of hospice and intensive care unit (ICU) care in the final week of life. Most U.S. clergy are Christian (98%) and affirm religious values despite a congregant's terminal diagnosis. Endorsement included God performing a miracle (86%), pursuing treatment because of the sanctity of life (54%), postponement of medical decisions because God is in control (28%), and enduring painful treatment because of redemptive suffering (27%). Life-prolonging religious values in end-of-life medical decisions were associated with fewer clergy-congregant conversations about considering hospice (adjusted odds ratio [AOR], 0.58; 95% CI 0.42-0.80), P < 0.0001), stopping treatment (AOR 0.58, 95% CI 0.41-0.84, P = 0.003), and forgoing future treatment (AOR 0.50, 95% CI 0.36-0.71, P < 0.001) but not associated with congregant receipt of hospice or ICU care. Clergy with lower medical knowledge were less likely to have certain end-of-life conversations. The absence of a clergy-congregant hospice discussion was associated with less hospice (AOR 0.45; 95% CI 0.29-0.66, P < 0.001) and more ICU care (AOR 1.67; 95% CI 1.14-2.50, P < 0.01) in the final week of life. American clergy hold religious values concerning end-of-life medical decisions, which appear to decrease end-of-life discussions. Clergy end-of-life education may enable better quality end-of-life care for religious patients. Copyright © 2017 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

Economics in "Global Health 2035": a sensitivity analysis of the value of a life year estimates.

Chang, Angela Y; Robinson, Lisa A; Hammitt, James K; Resch, Stephen C

2017-06-01

In "Global health 2035: a world converging within a generation," The Lancet Commission on Investing in Health (CIH) adds the value of increased life expectancy to the value of growth in gross domestic product (GDP) when assessing national well-being. To value changes in life expectancy, the CIH relies on several strong assumptions to bridge gaps in the empirical research. It finds that the value of a life year (VLY) averages 2.3 times GDP per capita for low- and middle-income countries (LMICs) assuming the changes in life expectancy they experienced from 2000 to 2011 are permanent. The CIH VLY estimate is based on a specific shift in population life expectancy and includes a 50 percent reduction for children ages 0 through 4. We investigate the sensitivity of this estimate to the underlying assumptions, including the effects of income, age, and life expectancy, and the sequencing of the calculations. We find that reasonable alternative assumptions regarding the effects of income, age, and life expectancy may reduce the VLY estimates to 0.2 to 2.1 times GDP per capita for LMICs. Removing the reduction for young children increases the VLY, while reversing the sequencing of the calculations reduces the VLY. Because the VLY is sensitive to the underlying assumptions, analysts interested in applying this approach elsewhere must tailor the estimates to the impacts of the intervention and the characteristics of the affected population. Analysts should test the sensitivity of their conclusions to reasonable alternative assumptions. More work is needed to investigate options for improving the approach.

What is the cost of a life in a disaster? - Examples, Practice and Global Analysis

NASA Astrophysics Data System (ADS)

Daniell, James; Kunz-Plapp, Tina; Schaefer, Andreas; Wenzel, Friedemann; Khazai, Bijan

2015-04-01

An analysis is presented based on historical evidence and global exposure metrics using the CATDAT Socioeconomic databases, in order to create a global distribution of the cost of life in a disaster using various metrics. Casualty insurance models require a value of life & mitigation and cost-benefit studies require a value of life in order to make decisions and set premiums. Although this is a contentious concept, there are two general approaches to human life costing: the first is based on human capital which looks at the production capacity and potential output as a proxy for future earning; the second looks at willingness to pay which estimates people's value on reducing risk and compensation payouts. A combination approach is used. For each of the 245 nations, a value of life is estimated using the following parameters:- (1) Age of people in a country using the life expectancy and distribution data in CATDAT (2) Output of the economy and wage distribution (3) Household and community interactions (4) Lost quality of life The range of statistical life costs are examined globally from different sources, with the range of a life value being from 10,000 up to in the order of 10 million between different countries. The difference of the cost for a fatality vs. that of a severe injury is also discussed with a severe injury often having higher costs than a fatality for loss purposes. The losses in terms of historical disasters are looked at and examined with the percentage of life cost shown as a proportion of total losses. The losses of a future major earthquake in a low seismicity region show some of the largest potential life cost losses with that of a M6.8 in Adelaide, Australia; having around 160 billion in life costs (25,000 deaths, 15,000 severe injuries). This study has benefits post-disaster for quantification of human capital losses in major disasters, and pre-disaster for the analysis of insurance and mitigation options.

The accountant as triage master: an economist's perspective on voluntary euthanasia and the value of life debate.

PubMed

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.

2015-01-01

Objective To estimate the willingness to pay (WTP) per quality-adjusted life year (QALY) value for life-saving treatments and to determine factors affecting the WTP per QALY value. Design A cross-sectional survey with multistage sampling and face-to-face interviews. Setting General population in the southern part of Thailand. Participants A total of 600 individuals were included in the study. Only 554 (92.3%) responses were usable for data analyses. Outcome measure Participants were asked for the maximum amount of WTP value for life-saving treatments by an open-ended question. EQ-5D-3L and visual analogue scale (VAS) were used to estimate additional QALY. Results The amount of WTP values varied from 0 to 720 000 Baht/year (approximately 32 Baht=US$1). The averages of additional QALY obtained from VAS and EQ-5D-3L were only slightly different (0.872 and 0.853, respectively). The averages of WTP per QALY obtained from VAS and EQ-5D-3L were 244720 and 243120 Baht/QALY, respectively. As compared to male participants, female participants were more likely to pay less for an additional QALY (p=0.007). In addition, participants with higher household incomes tended to have higher WTP per QALY values (p<0.001). Conclusions Our study added another WTP per QALY value specifically for life-saving treatments, which would complement the current cost-effectiveness threshold used in Thailand and optimise patient access to innovative treatments or technologies.

The development of memory efficiency and value-directed remembering across the life span: a cross-sectional study of memory and selectivity.

PubMed

Castel, Alan D; Humphreys, Kathryn L; Lee, Steve S; Galván, Adriana; Balota, David A; McCabe, David P

2011-11-01

Although attentional control and memory change considerably across the life span, no research has examined how the ability to strategically remember important information (i.e., value-directed remembering) changes from childhood to old age. The present study examined this in different age groups across the life span (N = 320, 5-96 years old). A selectivity task was used in which participants were asked to study and recall items worth different point values in order to maximize their point score. This procedure allowed for measures of memory quantity/capacity (number of words recalled) and memory efficiency/selectivity (the recall of high-value items relative to low-value items). Age-related differences were found for memory capacity, as young adults recalled more words than the other groups. However, in terms of selectivity, younger and older adults were more selective than adolescents and children. The dissociation between these measures across the life span illustrates important age-related differences in terms of memory capacity and the ability to selectively remember high-value information.

Half-lives of 214Pb and 214Bi.

PubMed

Martz, D E; Langner, G H; Johnson, P R

1991-10-01

New measurements on chemically separated samples of 214Bi have yielded a mean half-life value of 19.71 +/- 0.02 min, where the error quoted is twice the standard deviation of the mean based on 23 decay runs. This result provides strong support for the historic 19.72 +/- 0.04 min half-life value and essentially excludes the 19.9-min value, both reported in previous studies. New measurements of the decay rate of 222Rn progeny activity initially in radioactive equilibrium have yielded a value of 26.89 +/- 0.03 min for the half-life of 214Pb, where the error quoted is twice the standard deviation of the mean based on 12 decay runs. This value is 0.1 min longer than the currently accepted 214Pb half-value of 26.8 min.

High-Precision Half-Life Measurement for the Superallowed β+ Emitter 22Mg

NASA Astrophysics Data System (ADS)

Dunlop, Michelle

2017-09-01

High precision measurements of the Ft values for superallowed Fermi beta transitions between 0+ isobaric analogue states allow for stringent tests of the electroweak interaction. These transitions provide an experimental probe of the Conserved-Vector-Current hypothesis, the most precise determination of the up-down element of the Cabibbo-Kobayashi-Maskawa matrix, and set stringent limits on the existence of scalar currents in the weak interaction. To calculate the Ft values several theoretical corrections must be applied to the experimental data, some of which have large model dependent variations. Precise experimental determinations of the ft values can be used to help constrain the different models. The uncertainty in the 22Mg superallowed Ft value is dominated by the uncertainty in the experimental ft value. The adopted half-life of 22Mg is determined from two measurements which disagree with one another, resulting in the inflation of the weighted-average half-life uncertainty by a factor of 2. The 22Mg half-life was measured with a precision of 0.02% via direct β counting at TRIUMF's ISAC facility, leading to an improvement in the world-average half-life by more than a factor of 3.

Genetic value of herd life adjusted for milk production.

PubMed

Allaire, F R; Gibson, J P

1992-05-01

Cow herd life adjusted for lactational milk production was investigated as a genetic trait in the breeding objective. Under a simple model, the relative economic weight of milk to adjusted herd life on a per genetic standard deviation basis was equal to CVY/dCVL where CVY and CVL are the genetic coefficients of variation of milk production and adjusted herd life, respectively, and d is the depreciation per year per cow divided by the total fixed costs per year per cow. The relative economic value of milk to adjusted herd life at the prices and parameters for North America was about 3.2. An increase of 100-kg milk was equivalent to 2.2 mo of adjusted herd life. Three to 7% lower economic gain is expected when only improved milk production is sought compared with a breeding objective that included both production and adjusted herd life for relative value changed +/- 20%. A favorable economic gain to cost ratio probably exists for herd life used as a genetic trait to supplement milk in the breeding objective. Cow survival records are inexpensive, and herd life evaluations from such records may not extend the generation interval when such an evaluation is used in bull sire selection.

Evaluation of the 129I Half-Life Value Through Analyses of Primitive Meteorites

NASA Astrophysics Data System (ADS)

Pravdivtseva, Olga; Meshik, Alex; Hohenberg, Charles M.

The preserved record of decay of now-extinct 129I into 129Xe forms the basis of the I-Xe chronometer. Comparison of the high precision I-Xe and Pb-Pb ages of chondrules and pure mineral phases separated from eight meteorites suggests the 17.5 ÷ 14.6 Ma range for the 129I half-life, assuming that the 235U and 238U half-lives are correct. The mean value of 16 Ma indicates that the 15.7 Ma half-life of 129I used here for the I-Xe age calculations is most probably correct. Since the 129I half-life value only affects the relative I-Xe ages, the few Ma relative to the Shallowater standard, the absolute I-Xe ages are almost immune to this uncertainty in the 129I half-life.

2017-07-01

The study was carried out concerning value reference points and attitudes of native population of the Republic of Sakha (Yakutia) intended for health preservation. The analysis was applied to answers of 292 respondents residing in rural area of Yakutia. The analysis of answers of value motivation section demonstrated that for most respondents their health is a priority value of life. At that, most of respondents misunderstand and underestimate role of health in their life because they are unaware of health as an instrumental value. The health as an instrumental value gives its priority to persistence and diligence and hence ranks lower as compared with terminal value. The respondents assume that health mainly depends on diet, life-style, ecology. The results of analysis of answers to questions of "emotional" and "behavioral" sections testify in most of the respondents absence of comprehension about responsibility for one's own health, inadequate commitment to healthy life-style and passive attitude to health. The more active attitude to health is established in respondents of mature age that is rather related to deterioration of well-being feeling and presence of chronic diseases. In the younger age, most of respondents consider they are healthy and hence ignore prevention of diseases. Thereby, in spite of that health is mentioned by respondents as one of priority values most respondents are missing both attitudes to health preservation and clear-cut strategy of health-preserving behavior. In conditions of cardinal alteration of traditional way of life and life-style of native population of the North, behavioral habits of self-preserving behavior helping to survive in the severe climate conditions became inadequate. Nowadays, it is necessary to develop a new behavior strategy of health preservation.

Personal values influence behavior and decision making, but their long-term associations with health-related quality of life (HRQoL), frailty, and mortality are less clear. We studied these associations from midlife to old age in a 26-year follow-up of the Helsinki Businessmen Study (HBS) cohort. In 1974, 1320 clinically healthy men (born 1919-1934) reported in a 12-item questionnaire their personal values. In 2000, a mailed questionnaire, including assessment of HRQoL with RAND-36 (SF-36) instrument, was sent to survivors, and 1025 men responded. In 2000, the presence of phenotypic frailty was assessed using modified Fried criteria including indicators of shrinking, physical weakness, exhaustion, and physical inactivity. Mortality through December 31, 2000 was verified from national registries. Using a factor analysis, the data of the 12-item questionnaire of personal values were loaded in 3 factors: valuing health ("Health"), enjoyable and varying life ("Enjoyment"), and comfort and work-oriented life ("Work-life-balance"). Adjusted for age, we found a significant positive association between valuing "Health" in midlife and RAND-36 domains of Physical functioning (p = .032) and Vitality (p = .005) in old age. "Health" also predicted less frailty (p = .008), and "Enjoyment" was associated with higher mortality (p = .017). Value priorities of men assessed in midlife had long-term associations with HRQoL and frailty in old age, and they may also predict mortality.

Economics in “Global Health 2035”: a sensitivity analysis of the value of a life year estimates

PubMed Central

Chang, Angela Y; Robinson, Lisa A; Hammitt, James K; Resch, Stephen C

2017-01-01

Background In “Global health 2035: a world converging within a generation,” The Lancet Commission on Investing in Health (CIH) adds the value of increased life expectancy to the value of growth in gross domestic product (GDP) when assessing national well–being. To value changes in life expectancy, the CIH relies on several strong assumptions to bridge gaps in the empirical research. It finds that the value of a life year (VLY) averages 2.3 times GDP per capita for low– and middle–income countries (LMICs) assuming the changes in life expectancy they experienced from 2000 to 2011 are permanent. Methods The CIH VLY estimate is based on a specific shift in population life expectancy and includes a 50 percent reduction for children ages 0 through 4. We investigate the sensitivity of this estimate to the underlying assumptions, including the effects of income, age, and life expectancy, and the sequencing of the calculations. Findings We find that reasonable alternative assumptions regarding the effects of income, age, and life expectancy may reduce the VLY estimates to 0.2 to 2.1 times GDP per capita for LMICs. Removing the reduction for young children increases the VLY, while reversing the sequencing of the calculations reduces the VLY. Conclusion Because the VLY is sensitive to the underlying assumptions, analysts interested in applying this approach elsewhere must tailor the estimates to the impacts of the intervention and the characteristics of the affected population. Analysts should test the sensitivity of their conclusions to reasonable alternative assumptions. More work is needed to investigate options for improving the approach. PMID:28400950

How Should We Value a Planet?

NASA Astrophysics Data System (ADS)

Haqq-Misra, J.

2014-04-01

The idea that a planet or its biota may be intrinsically valuable, apart from its usefulness to humans, is contentious among ethicists, while difficulties abound in attempting to decide what is objectively better or worse for a planet or life. As a way of dissecting the issue of value and life, I present a two-axis comparative tool for ethical frameworks that considers the intrinsic or instrumental value placed upon organisms, environments, planetary systems, and space. I discuss ethical considerations relevant to contemporary space exploration, near-future human exploration of Solar System bodies, and long-term possibilities of interplanetary colonization. This allows for more transparent discussions of value with regard to future space exploration or the discovery of extraterrestrial life.

To quantify agreement between patients and their family members on their own values and preferences for use or non-use of life-sustaining treatments for the patient. Hospitalised patients aged 55 years or older with advanced pulmonary, cardiac, liver disease or metastatic cancer or aged 80 years or older from medical wards at 16 Canadian hospitals and their family members completed a questionnaire including eight items about values related to life-sustaining treatment and a question about preferences for life-sustaining treatments. We recruited a total of 313 patient-family member dyads. Crude agreement between patients and family members about values related to life-sustaining treatment was 42% across all eight items but varied widely: 20% when asking how important it was for the patient to respect the wishes of family members regarding their care; 72% when asking how important it was for the patient to be kept comfortable and suffer as little as possible. Crude agreement on preferences for life-sustaining treatment was 91% (kappa 0.60; 95%CI 0.45 to 0.75) when looking at preferences for cardiopulmonary resuscitation (CPR) versus no CPR but fell to 56% when including all five response options with varying degrees of resuscitative, medical or comfort options (kappa 0.39; 95%CI 0.31 to 0.47). There is appreciable disagreement between seriously ill hospitalised patients and family members in their values and preferences for life-sustaining treatment. Strategies are needed to improve the quality of advance care planning, so that surrogates are better able to honour patient's wishes at the end of life. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Beyond QALYs: Multi-criteria based estimation of maximum willingness to pay for health technologies.

PubMed

Nord, Erik

2018-03-01

The QALY is a useful outcome measure in cost-effectiveness analysis. But in determining the overall value of and societal willingness to pay for health technologies, gains in quality of life and length of life are prima facie separate criteria that need not be put together in a single concept. A focus on costs per QALY can also be counterproductive. One reason is that the QALY does not capture well the value of interventions in patients with reduced potentials for health and thus different reference points. Another reason is a need to separate losses of length of life and losses of quality of life when it comes to judging the strength of moral claims on resources in patients of different ages. An alternative to the cost-per-QALY approach is outlined, consisting in the development of two bivariate value tables that may be used in combination to estimate maximum cost acceptance for given units of treatment-for instance a surgical procedure, or 1 year of medication-rather than for 'obtaining one QALY.' The approach is a follow-up of earlier work on 'cost value analysis.' It draws on work in the QALY field insofar as it uses health state values established in that field. But it does not use these values to weight life years and thus avoids devaluing gained life years in people with chronic illness or disability. Real tables of the kind proposed could be developed in deliberative processes among policy makers and serve as guidance for decision makers involved in health technology assessment and appraisal.

Ethical dimensions of quality of life in aging: autonomy vs. collectivism in the United States and Canada.

PubMed

Clark, P G

1991-10-01

Ethical concepts lie at the core of how quality of life in aging is defined and enhanced. Although recent American attention has been largely focused on autonomy as an important value for quality of life in old age, there is real danger in emphasizing personal independence at the expense of community or collectivism. This conceptual analysis compares and contrasts these value orientations in the U.S. and Canada and examines their relationship to the concept of quality of life in aging. It also explores implications of the analysis for expanding our understanding of the importance of value dimensions in comparative gerontology, and suggests ways of integrating individualistic and collectivistic ideals in gerontological policies and programs.

"Nasi Uduk" is one of the Indonesian traditional food made from rice, steamed with coconut milk and seasoning. For optimizing shelf-life, canned "nasi uduk" for military and disaster-response ration, was packed using cylindrical cans of 72,63 × 53,04 mm (Ø × h) in size. One of the important aspects on quality assessment of preserved product was its rancidity. The aim of this research was to determine shelf-life of canned "nasi uduk" using ASLT method of Arrhenius model. Storage temperatures set up at 35, 45 and 55°C for 35 days. Optimization of sterilization process was conducted to achieve the optimum conditions of sterilization. Target lethality value (Fo), microorganism total plate count (TPC) and rancidity levels (TBA) were used as parameters in this research. The results showed that the optimum sterilization conditions were 121 °C for 20 minutes, TPC value of 9.5 × 101 CFU/ml and Fo value 4.14 minutes. Predicted shelf-life of canned "nasi uduk" was 9.6 months which was average TBA value still bellow of the critical point.

This study describes the impact of diabetes and the meaning of health-related quality of life (HRQOL) for 22 male and female patients in Korea. Open-ended interviews yielded six HRQOL themes: health, overall well-being, harmonious relationships and family responsibilities, a rewarding life, spiritual life, and material support. The physical impact of diabetes included decreased energy, limitations, and physical suffering; while its psychological/spiritual impact extended to general stress, helplessness, fear, depression, anger, and relationship with God. Like Americans, Koreans valued health, psychological well-being and interpersonal support. In addition, the Koreans valued smooth, harmonious interpersonal relationships, overall well-being pertaining to living a comfortable and honorable life.

Generation of Finite Life Distributional Goodman Diagrams for Reliability Prediction

NASA Technical Reports Server (NTRS)

Kececioglu, D.; Guerrieri, W. N.

1971-01-01

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.

Can Broader Diffusion of Value-Based Insurance Design Increase Benefits from US Health Care without Increasing Costs? Evidence from a Computer Simulation Model

Background Evidence suggests that cost sharing (i.e.,copayments and deductibles) decreases health expenditures but also reduces essential care. Value-based insurance design (VBID) has been proposed to encourage essential care while controlling health expenditures. Our objective was to estimate the impact of broader diffusion of VBID on US health care benefits and costs. Methods and Findings We used a published computer simulation of costs and life expectancy gains from US health care to estimate the impact of broader diffusion of VBID. Two scenarios were analyzed: (1) applying VBID solely to pharmacy benefits and (2) applying VBID to both pharmacy benefits and other health care services (e.g., devices). We assumed that cost sharing would be eliminated for high-value services (<$100,000 per life-year), would remain unchanged for intermediate- or unknown-value services ($100,000–$300,000 per life-year or unknown), and would be increased for low-value services (>$300,000 per life-year). All costs are provided in 2003 US dollars. Our simulation estimated that approximately 60% of health expenditures in the US are spent on low-value services, 20% are spent on intermediate-value services, and 20% are spent on high-value services. Correspondingly, the vast majority (80%) of health expenditures would have cost sharing that is impacted by VBID. With prevailing patterns of cost sharing, health care conferred 4.70 life-years at a per-capita annual expenditure of US$5,688. Broader diffusion of VBID to pharmaceuticals increased the benefit conferred by health care by 0.03 to 0.05 additional life-years, without increasing costs and without increasing out-of-pocket payments. Broader diffusion of VBID to other health care services could increase the benefit conferred by health care by 0.24 to 0.44 additional life-years, also without increasing costs and without increasing overall out-of-pocket payments. Among those without health insurance, using cost saving from VBID to subsidize insurance coverage would increase the benefit conferred by health care by 1.21 life-years, a 31% increase. Conclusion Broader diffusion of VBID may amplify benefits from US health care without increasing health expenditures. Please see later in the article for the Editors' Summary PMID:20169114

Research on shelf-life prediction of canned fried rice using Accelerated Shelf-life Test (ASLT) of Arrhenius model has been conducted. The aim of this research to predict shelf life of canned-fried rice products. Lethality value of 121°C for 15 and 20 minutes and Total Plate count methods are used to determine time and temperatures of sterilization process.Various storage temperatures of ASLT Arrhenius method were 35, 45 and 55°C during 35days. Rancidity is one of the derivation quality of canned fried rice. In this research, sample of canned fried rice is tested using rancidity value (TBA). TBA value was used as parameter which be measured once a week periodically. The use of can for fried rice without any chemical preservative is one of the advantage of the product, additionaly the use of physicalproperties such as temperature and pressure during its process can extend the shelf life and reduce the microbial contamination. The same research has never done before for fried rice as ready to eat meal. The result showed that the optimum conditions of sterilization process were 121°C,15 minutes with total plate count number of 9,3 × 101 CFU/ml. Lethality value of canned fried rice at 121°C,15 minutes was 3.63 minutes. The calculated Shelf-life of canned fried rice using Accelerated Shelf-life Test (ASLT) of Arrhenius method was 10.3 months.

1 Pharmacokinetics and bioavailability of brotizolam after i.v. and oral administration were studied in healthy young volunteers. 2 Kinetic parameters after i.v. administration were: volume of distribution 0.66 ± 0.19 1/kg, total plasma clearance 113 ± 28 ml/min, distribution half-life 11 ± 6 min, and elimination half-life 4.8 ± 1.4 h (mean values ± s.d.). 3 Kinetic parameters after oral administration were: absorption lag-time 8 ± 12 min, absorption half-life 10 ± 11 min, and elimination half-life 5.1 ± 1.2 h (mean values ± s.d.). 4 Bioavailability of brotizolam was 70 ± 22% when calculated by comparing oral and intravenous area-under-curve values, corrected for intra-individual half-life differences. An alternative calculation method, which is relatively independent of large clearance variations, provided a bioavailability of 70 ± 24% (range: 47-117%). PMID:6661374

Update on value-based medicine.

PubMed

Brown, Melissa M; Brown, Gary C

2013-05-01

To update concepts in Value-Based Medicine, especially in view of the Patient Protection and Affordable Care Act. The Patient Protection and Affordable Care Act assures that some variant of Value-Based Medicine cost-utility analysis will play a key role in the healthcare system. It identifies the highest quality care, thereby maximizing the most efficacious use of healthcare resources and empowering patients and physicians.Standardization is critical for the creation and acceptance of a Value-Based Medicine, cost-utility analysis, information system, since 27 million different input variants can go into a cost-utility analysis. Key among such standards is the use of patient preferences (utilities), as patients best understand the quality of life associated with their health states. The inclusion of societal costs, versus direct medical costs alone, demonstrates that medical interventions are more cost effective and, in many instances, provide a net financial return-on-investment to society referent to the direct medical costs expended. Value-Based Medicine provides a standardized methodology, integrating critical, patient, quality-of-life preferences, and societal costs, to allow the highest quality, most cost-effective care. Central to Value-Based Medicine is the concept that all patients deserve the interventions that provide the greatest patient value (improvement in quality of life and/or length of life).

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

PubMed

Elvik, Rune

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.

Background Cystic fibrosis (CF) is a chronic, life-shortening disease with a significant treatment burden. To support young adults with CF in their everyday life, we previously conducted a life coaching feasibility trial (published elsewhere). The aim of the current study was to explore how life coaching was experienced by study participants within the context of their lives with CF. Methods A qualitative study using individual interviews. Respondents (n=14) were recruited from the intervention group after participation in life coaching. Data were analyzed from a phenomenologic-hermeneutical perspective, inspired by Ricoeur’s theory. Findings Periodic exacerbations of CF led to worry about disease progression, and interrupted the respondents’ ability to fulfill daily life roles satisfactory. The treatment burden demanded self-discipline and this was sometimes at the expense of social life or career. The young adults rarely spoke to others about their situation; therefore, they valued opening up to a professional coach about life and concerns. We identified three themes: 1) living an unpredictable life; 2) the conflict between freedom and the constraints of illness; and 3) the value of telling one’s story. In relation to all three themes, coaching promoted reflection over life situations, reframed thoughts, and facilitated finding new ways to manage everyday life. Conclusion Life coaching is an intervention that is valued for those who feel challenged by their CF disease. Coaching programs should be designed to include the participants, when they feel a need for coaching and are open for change. Screening parameters to identify persons who will most likely benefit from life coaching are needed. PMID:29720874

The vestiges of life in Eoarchean rocks have the potential to elucidate the origin of life. However, gathering evidence from many terrains is not always possible, and biogenic graphite has thus far been found only in the 3.7-3.8 Ga (gigayears ago) Isua supracrustal belt. Here we present the total organic carbon contents and carbon isotope values of graphite (δ13Corg) and carbonate (δ13Ccarb) in the oldest metasedimentary rocks from northern Labrador. Some pelitic rocks have low δ13Corg values of -28.2, comparable to the lowest value in younger rocks. The consistency between crystallization temperatures of the graphite and metamorphic temperature of the host rocks establishes that the graphite does not originate from later contamination. A clear correlation between the δ13Corg values and metamorphic grade indicates that variations in the δ13Corg values are due to metamorphism, and that the pre-metamorphic value was lower than the minimum value. We concluded that the large fractionation between the δ13Ccarb and δ13Corg values, up to 25‰, indicates the oldest evidence of organisms greater than 3.95 Ga. The discovery of the biogenic graphite enables geochemical study of the biogenic materials themselves, and will provide insight into early life not only on Earth but also on other planets.

Direct observation of the 218Po alpha-peak decay with a microcomputer-controlled alpha-spectrometer yielded a mean half-life value of 3.040 +/- 0.008 min, where the error quoted represents twice the standard deviation of the means from 38 separate decay measurements. The 1912 and 1924 218Po half-life measurements, which provided the 3.05-min value listed in nuclear tables for the past 60 y, are critically reviewed. Two more recent experiments, which yielded longer values of 3.11 min (Van Hise et al. 1982) and 3.093 min (Potapov and Soloshenkov 1986), are also discussed.

Vision and quality-of-life.

PubMed Central

Brown, G C

1999-01-01

OBJECTIVE: To determine the relationship of visual acuity loss to quality of life. DESIGN: Three hundred twenty-five patients with visual loss to a minimum of 20/40 or greater in at least 1 eye were interviewed in a standardized fashion using a modified VF-14, questionnaire. Utility values were also obtained using both the time trade-off and standard gamble methods of utility assessment. MAIN OUTCOME MEASURES: Best-corrected visual acuity was correlated with the visual function score on the modified VF-14 questionnaire, as well as with utility values obtained using both the time trade-off and standard gamble methods. RESULTS: Decreasing levels of vision in the eye with better acuity correlated directly with decreasing visual function scores on the modified VF-14 questionnaire, as did decreasing utility values using the time trade-off method of utility evaluation. The standard gamble method of utility evaluation was not as directly correlated with vision as the time trade-off method. Age, level of education, gender, race, length of time of visual loss, and the number of associated systemic comorbidities did not significantly affect the time trade-off utility values associated with visual loss in the better eye. The level of reduced vision in the better eye, rather than the specific disease process causing reduced vision, was related to mean utility values. The average person with 20/40 vision in the better seeing eye was willing to trade 2 of every 10 years of life in return for perfect vision (utility value of 0.8), while the average person with counting fingers vision in the better eye was willing to trade approximately 5 of every 10 remaining years of life (utility value of 0.52) in return for perfect vision. CONCLUSIONS: The time trade-off method of utility evaluation appears to be an effective method for assessing quality of life associated with visual loss. Time trade-off utility values decrease in direct conjunction with decreasing vision in the better-seeing eye. Unlike the modified VF-14 test and its counterparts, utility values allow the quality of life associated with visual loss to be more readily compared to the quality of life associated with other health (disease) states. This information can be employed for cost-effective analyses that objectively compare evidence-based medicine, patient-based preferences and sound econometric principles across all specialties in health care.

Gánti's chemoton model of the minimal chemical organization of living systems and life criteria for the living state and a living world are characterized. It is argued that these are better interpreted as part of a heuristic pursuit of an exact theoretical biology than as a "definition of life." Several problems with efforts to define life are discussed. Clarifying the proper use of Gánti's ideas to serve constructive engineering idealizations helps to show their enduring value.

2017-09-01

Caring for a relative with dementia is associated with physical and emotional health problems in caregivers. There are no studies analysing the role of personal values in the caregiver stress process. This study aims to analyse the psychometric properties of the Valued Living Questionnaire Adapted to Caregiving (VLQAC), and to explore the relationship between personal values and stressors, coping strategies and caregiver distress. A total of 253 individual interviews with caregivers of relatives with dementia were conducted, and the following variables were assessed: personal values, stressors, cognitive fusion, emotional acceptance, depression, anxiety, and satisfaction with life. An exploratory factor analysis and hierarchical regression analyses were carried out. Two factors were obtained, Commitment to Own Values and Commitment to Family Values which explain 43.42% of variance, with reliability coefficients (Cronbach's alpha) of .76 and .61, respectively. Personal values had a significant effect on emotional distress (depression and anxiety) and satisfaction with life, even when controlling for socio-demographic variables, stressors and coping strategies. Results suggest that the personal values construct of dementia caregivers is two-dimensional. The personal values of the caregivers play an important role in accounting for distress and satisfaction with life in this population.

To estimate the willingness to pay (WTP) per quality-adjusted life year (QALY) value for life-saving treatments and to determine factors affecting the WTP per QALY value. A cross-sectional survey with multistage sampling and face-to-face interviews. General population in the southern part of Thailand. A total of 600 individuals were included in the study. Only 554 (92.3%) responses were usable for data analyses. Participants were asked for the maximum amount of WTP value for life-saving treatments by an open-ended question. EQ-5D-3L and visual analogue scale (VAS) were used to estimate additional QALY. The amount of WTP values varied from 0 to 720,000 Baht/year (approximately 32 Baht=US$1). The averages of additional QALY obtained from VAS and EQ-5D-3L were only slightly different (0.872 and 0.853, respectively). The averages of WTP per QALY obtained from VAS and EQ-5D-3L were 244,720 and 243,120 Baht/QALY, respectively. As compared to male participants, female participants were more likely to pay less for an additional QALY (p=0.007). In addition, participants with higher household incomes tended to have higher WTP per QALY values (p<0.001). Our study added another WTP per QALY value specifically for life-saving treatments, which would complement the current cost-effectiveness threshold used in Thailand and optimise patient access to innovative treatments or technologies.

To explore specific cultural and religious beliefs and values concerning death and dying, truth telling, and advance care planning, and the preferences for end-of-life care among older persons from culturally and linguistically diverse backgrounds. Whilst literature indicates that culture impacts on end-of-life decision-making significantly, there is limited evidence on the topic. A cross-sectional survey. A total of 171 community older persons who make regular visits to 17 day care centres expressed in a questionnaire their; (1) beliefs about death and dying, truth telling, and advance care planning, and (2) preferences for end-of-life care. More than 92% of respondents believed that dying is a normal part of life, and more than 70% felt comfortable talking about death. Whilst respondents accepted dying as a normal part of life, 64% of Eastern Europeans and 53% of Asia/Pacific groups believed that death should be avoided at all costs. People from the Asia/Pacific group reported the most consensual view against all of the life-prolonging measures. Cultural and religious beliefs and values may have an impact on preferences for treatment at end-of-life. The study offers nurses empirical data to help shape conversations about end-of-life care, and thus to enhance their commitment to help people 'die well'. Information acquisition to extend understanding of each individual before proceeding with documentation of advance care planning is essential and should include retrieval of individuals' cultural and religious beliefs and values, and preferences for care. An institutional system and/or protocol that promote conversations about these among nurses and other healthcare professionals are warranted. © 2016 John Wiley & Sons Ltd.

Brain injury can be identified as early as day two of life in asphyxiated newborns treated with hypothermia, when using diffusion magnetic resonance imaging (MRI). However, it remains unclear whether these diffusion changes can predict future neurodevelopment. This study aimed to determine whether abnormal early diffusion changes in newborns treated with hypothermia are associated with adverse neurodevelopmental outcome at age two years. Asphyxiated newborns treated with hypothermia were enrolled prospectively. They underwent magnetic resonance imaging (MRI) at specific time points over the first month of life, including diffusion-weighted imaging and diffusion-tensor imaging. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values were measured in different regions of interest. Adverse neurodevelopmental outcome was defined as cerebral palsy, global developmental delay, and/or seizure disorder around age two years. ADC and FA values were compared between the newborns developing or not developing adverse outcome. Twenty-nine asphyxiated newborns treated with hypothermia were included. Among the newborns developing adverse outcome, ADC values were significantly decreased on days two to three of life and increased around day ten of life in the thalamus, posterior limb of the internal capsule, and the lentiform nucleus. FA values decreased in the same regions around day 30 of life. These newborns also had increased ADC around day ten of life and around day 30 of life, and decreased FA around day 30 of life in the anterior and posterior white matter. Diffusion changes that were evident as early as day two of life, when the asphyxiated newborns were still treated with hypothermia, were associated with later abnormal neurodevelopmental outcome.

'In a twilight world'? Judging the value of life for the minimally conscious patient.

PubMed

Huxtable, Richard

2013-09-01

The recent ruling from England on the case of M is one of very few worldwide to consider whether life-sustaining treatment, in the form of clinically assisted nutrition and hydration, should continue to be provided to a patient in a minimally conscious state. Formally concerned with the English law pertaining to precedent autonomy (specifically advance decision-making) and the best interests of the incapacitated patient, the judgment issued in M's case implicitly engages with three different accounts of the value of human life, which respectively emphasise its self-determined, intrinsic and instrumental value. The judge appeared to be most persuaded by the intrinsic value of life and he concluded that treatment ought to continue. Assessing whether his approach or conclusion were ethically appropriate involves significant substantive and evidential questions regarding where the burden of proof should lie and what standard of proof should be required when decisions are to be made about the fates of patients inhabiting 'twilight worlds'.

Associations between women's subjective perceptions of daily occupations and life satisfaction, and the role of perceived control.

PubMed

Håkansson, Carita; Björkelund, Cecilia; Eklund, Mona

2011-12-01

More knowledge is needed about the role of perceived control in the associations between different perceptions of daily occupations and positive health outcomes. The aim was to explore the associations between different subjective perceptions of daily occupations, in terms of occupational balance, occupational meaning, occupational value and satisfaction with occupations, and life satisfaction, and the role of perceived control in those associations. A questionnaire including questions about perceptions of daily occupations, perceived control and life satisfaction were answered by a random sample of 488 middle-aged Swedish women. Multiple logistic regression analysis was used to test the associations between perceptions of daily occupations and life satisfaction, and the role of perceived control. After adjustments for perceived control women who perceived a high level of satisfaction with work and leisure, occupational balance, occupational meaning and occupational value perceived greater life satisfaction than the other women. Perceived control was not significant in the model. It seems that occupational balance and occupational meaning were pivotal for the women's life satisfaction, but satisfaction with work and leisure, as well as perceived occupational value, was also of importance. The assumption that perceived control would have a role in the association between perceptions of occupations and life satisfaction was not confirmed. The results indicate that occupational therapists need to focus on occupational balance, occupational meaning, occupational value and satisfaction with work and leisure to promote positive health outcomes, in terms of life satisfaction, when working with middle-aged female clients. © 2011 The Authors.

Valuing reduced antibiotic use for pediatric acute otitis media.

PubMed

Meropol, Sharon B

2008-04-01

The 2004 American Academy of Pediatrics acute otitis media guidelines urge parents to weigh the benefits of reduced antibiotic use, adverse drug events, and future resistance versus risks of extra costs and sick days resulting from guideline use. The value of decreased antibiotic resistance has not been quantified. The objective was to perform cost-utility analysis, estimating the resistance value of implementing the guidelines for acute otitis media treatment for children <2 years of age. Outcomes were described with a common denominator and the value of avoiding resistance was estimated using a parental perspective. Decision analysis results were used for outcome probabilities. Published utilities were used to describe outcomes in quality-adjusted life-day units. The minimum resistance benefit value, where the benefits of the American Academy of Pediatrics guidelines would at least balance their costs, was defined as the guidelines' incremental costs minus their other benefits. For a child 2 to <6 months of age presenting to a primary care physician with possible otitis media, parents would need to value the resistance benefit at 0.77 quality-adjusted life-days per antibiotic prescription avoided for the guidelines' benefits to balance their costs. For the 6- to <24-month-old group, results were 0.67 quality-adjusted life-days per prescription avoided. Results were sensitive to the dollar cost utility; when willingness to pay ranged from $20,000 to $200,000 per quality-adjusted life-year, results ranged from 0.36 and 0.30 quality-adjusted life-days up to 4.10 and 3.57 quality-adjusted life-days for the 2- to <6-month-old and 6- to <24-month-old groups, respectively. Costs were driven by missed parent work days. From a societal perspective, trading 0.30 to 4 quality-adjusted life-days to avoid 1 antibiotic course might be desirable; from a parental perspective, this may not be as desirable. Parent demand for antibiotics may be rational when driven by the value of parent time. Other approaches that have the potential to reduce antibiotic use, such as wider use of influenza vaccine and improved rapid viral diagnostic techniques, might be more successful.

Increases in adult life expectancy in rural South Africa: valuing the scale-up of HIV treatment

PubMed Central

Bor, Jacob; Herbst, Abraham J; Newell, Marie-Louise; Bärnighausen, Till

2013-01-01

The scale-up of antiretroviral therapy (ART) is expected to raise adult life expectancy in populations with high HIV prevalence. Using data from a population cohort of over 101,000 individuals in rural KwaZulu-Natal, South Africa, we measured changes in adult life expectancy for 2000–2011. In 2003, the year before ART became available in the public sector health system, adult life expectancy was 49.2 years; by 2011, adult life expectancy had increased to 60.5 years – an 11.3-year gain. Based on standard monetary valuation of life, the survival benefits of ART far outweigh the costs of providing treatment in this community. These gains in adult life expectancy signify the social value of ART and have implications for investment decisions of individuals, governments, and donors. PMID:23430655

Valuing lives and allocating resources: a defense of the modified youngest first principle of scarce resource distribution.

PubMed

Tallman, Ruth

2014-06-01

In this paper, I argue that the 'modified youngest first' principle provides a morally appropriate criterion for making decisions regarding the distribution of scarce medical resources, and that it is morally preferable to the simple 'youngest first' principle. Based on the complete lives system's goal of maximizing complete lives rather than individual life episodes, I argue that essential to the value we see in complete lives is the first person value attributed by the experiencer of that life. For a life to be 'complete' or 'incomplete,' the subject of that life must be able to understand the concept of a complete life, to have started goals and projects, and to know what it would be for that life to be complete. As the very young are not able to do this, it can reasonably be said that their characteristically human lives have not yet begun, giving those accepting a complete lives approach good reason to accept the modified youngest first principle over a simple 'youngest first' approach. © 2012 John Wiley & Sons Ltd.

The value of a statistical life: a meta-analysis with a mixed effects regression model.

PubMed

Bellavance, François; Dionne, Georges; Lebeau, Martin

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.

Preference-based comparative effectiveness and cost–effectiveness: a review and relevance of value-based medicine for vitreoretinal interventions.

PubMed

Brown, Melissa M; Brown, Gary C; Lieske, Heidi B; Lieske, P Alexander

2012-05-01

This analysis discusses the comparative effectiveness and cost-effectiveness of vitreoretinal interventions, measured in quality-adjusted life years (QALYs) and percentage patient value (PPV gain, or improvement in quality of life and/or length of life). The material is relevant since the Patient Protection and Affordable Care Act enacted by Congress with the support of the President has emphasized the critical importance of patient-based preferences. The majority of preference-based, comparative effectiveness and cost-effectiveness vitreoretinal interventions assessed in the US healthcare literature are Value-Based Medicine analyses, thus comparable. These interventions confer a mean patient (human) value gain (improvement in quality of life) of 8.3% [SD 6.3%, 95% confidence interval (CI) + 2.6%]. The average cost-utility of these vitreoretinal interventions is US$23 026/QALY (SD US$24 508, 95% CI + US$8770). Most vitreoretinal interventions are very cost effective using a conventional US standard of US$50 000/QALY as the upper anchor for a very cost-effective intervention, and the World Health Organization of approximately US$142 200/QALY as the upper anchor for a cost-effective intervention. Most vitreoretinal interventions confer considerable patient value and are very cost effective. Further standardization across healthcare is needed in the preference-based, comparative and cost-utility (cost-effectiveness) arena. The metrics of PPV (percentage patient value) gain and US$/PPV (dollars expended per percentage patient value gain) or financial value gain may be more user-friendly than the QALY.

2016-01-01

Background To assess the impact of oral mucosa lesions on quality of life related to oral health (QLROH) and additionally to establish whether the etiopathogenicy of oral lesion is associated to the degree of QLROH impact. Material and Methods In this cross-sectional study performed on a non-probability sample of 247 consecutively patients attending the oral medicine and pathology clinic the Spanish version of Oral Health Impact Profile-49 questionnaire (OHIP-49-mx) was applied. Responses were recorded on Likert-type scale whose values ranged from 0 (never) to 4 (always). Values greater than the 50 percentile (median) were considered as indicative of poor quality of life. All patients were orally examined and diagnosed. In accordance to their etiopathogenicy 6 study groups were formed: 4 corresponded to MIND classification for diseases (Metabolic, Inflammatory, Neoplastic, and Development groups), with ≥2 diseases and no-lesion group. To identify possible differences of OHIP-49 values between study groups an ANOVA (one factor) parametric and a chi square tests were performed (SPSS®20.0). Results The OHIP-49-mx values were higher than the 50 percentile (established at 39) in metabolic, inflammatory, development, and ≥2 diseases groups, suggesting that this type of oral lesions negatively impact the quality of life. ≥2 diseasesgroup followed by metabolic and inflammatory diseases group (p 0.001) depicted worst quality of life. Functional limitation (p 0.003), pain, physical inability (p 0.001) and psychological disabilities dimensions exhibited greater values in all groups. Conclusions Injured oral mucosa negatively impacts quality of life, specifically functional limitation, physical inability and psychological disabilities could lead to social isolation.To our knowledge, this is the first time that an association between QLROH and the etiopathogenicy of oral mucosal diseases is established. Key words:Quality of life, quality of life related to oral health, oral mucosa lesions, etiopathogenicy, MIND classification. PMID:26827060

[The metaphysical dimension of animal ethics].

PubMed

Walz, Norbert

2008-01-01

Utilitarian ethics recognises animals as moral objects, but it does not attribute an absolute value to human or non-human individuals. Animal ethics according to Regan defines the non-human individual as an inherent value, but concedes that humans should be given precedence over animals if a situation involves a decision between life and death. Such life and death decisions relate to the fundamental structures of biological nature. To individuals these fundamental structures (the paradox of life and death) will necessarily appear absurd. The metaphysical dimension of animal ethics tries to shed light on the connections between life and death, body and mind that underly ethical discussions and searches for alternatives to the natural organisation of life.

A Comparison of the Influence of Anticipated Death Trajectory and Personal Values on End-of-Life Care Preferences: A Qualitative Analysis.

Supiano, Katherine P; McGee, Nancy; Dassel, Kara B; Utz, Rebecca

2017-08-17

We examined anticipated preferences for end-of-life (EOL) care in healthy older adults in the context of various terminal disease scenarios to explore the relationship between personal values and diseases and conditions that would influence EOL care choices. Qualitative Descriptive Analysis was used to derive themes and the relationship between EOL preference themes and personal value themes in 365 respondents in a national sample of healthy older adults who completed a survey on their anticipated preferences for end-of-life (EOL) care. Reluctance to burden close others was the most frequently voiced personal value across all conditions affecting EOL preferences, followed by the personal value of quality of life. Concern about whether one's wishes would be honored was more commonly voiced in the context of hypothetical, prospective terminal cancer than in neurological conditions. Respondents who voiced desire for autonomy in how they would die clearly attributed extreme pain as the primary influence on EOL preferences. Comprehensive assessment of patient personal values should include consideration of particular chronic disease scenarios and death trajectories to fully inform EoL preferences. Because personal values do influence EOL preferences, care should be taken to ascertain patient values when presenting diagnoses, prognoses, and treatment options. In particular, patients and families of patients with progressive neurological diseases will likely face a time when the patient cannot self-represent EOL wishes. Early discussion of values and preferences, particularly in the context of cognitive disease is vital to assure patient-directed care.

2014-01-01

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

Objectives The aims of this study were to evaluate correlates and predictors of life functioning and quality of life in bipolar disorder during a comparative effectiveness trial of moderate doses of lithium. Methods In the Lithium treatment moderate-dose use study (LiTMUS), 283 symptomatic outpatients with bipolar disorder type I or II were randomized to receive lithium plus ”optimal personalized treatment (OPT), or OPT alone. Participants were assessed using structured diagnostic interviews, clinician-rated blinded assessments, and questionnaires. We employ linear mixed effects models to test the effect of treatment overall and adjunct lithium specifically on quality of life or functioning. Similar models are used to examine the association of baseline demographics and clinical features with quality of life and life functioning. Results Quality of life and impaired functioning at baseline were associated with lower income, higher depressive severity, and more psychiatric comorbid conditions. Over six months, patients in both treatment groups improved in quality of life and life functioning (p-values < 0.0001); without a statistically significant difference between the two treatment groups (p-values > 0.05). Within the lithium group, improvement in quality of life and functioning were not associated with concurrent lithium levels at week 12 or week 24 (p-values > 0.05). Lower baseline depressive severity and younger age of onset predicted less improvement in functioning over six months. Conclusions Optimized care for bipolar disorder improves overall quality of life and life functioning, with no additional benefit from adjunct moderate doses of lithium. Illness burden and psychosocial stressors were associated with worse quality of life and lower functioning in individuals with bipolar disorder. PMID:25194782

Broadening Participation in the Life Sciences with Social-Psychological Interventions.

PubMed

Tibbetts, Yoi; Harackiewicz, Judith M; Priniski, Stacy J; Canning, Elizabeth A

Randomized controlled trials (RCTs) have recently documented the positive effects of social-psychological interventions on the performance and retention of underrepresented students in the life sciences. We review two types of social-psychological interventions that address either students' well-being in college science courses or students' engagement in science content. Interventions that have proven effective in RCTs in science courses (namely, utility-value [UV] and values-affirmation [VA] interventions) emphasize different types of student values-students' perceptions of the value of curricular content and students' personal values that shape their educational experiences. Both types of value can be leveraged to promote positive academic outcomes for underrepresented students. For example, recent work shows that brief writing interventions embedded in the curriculum can increase students' perceptions of UV (the perceived importance or usefulness of a task for future goals) and dramatically improve the performance of first-generation (FG) underrepresented minority students in college biology. Other work has emphasized students' personal values in brief essays written early in the semester. This VA intervention has been shown to close achievement gaps for women in physics classes and for FG students in college biology. By reviewing recent research, considering which interventions are most effective for different groups, and examining the causal mechanisms driving these positive effects, we hope to inform life sciences educators about the potential of social-psychological interventions for broadening participation in the life sciences. © 2016 Y.

Human dignity: intrinsic or relative value?

PubMed

Thiel, Marie-Jo

2010-09-01

Is human dignity an intrinsic value? Or is it a relative value, depending on the perception or assessment of quality of life? History had delineated some of its key features, but the advent of human rights and the Holocaust put special emphasis on this notion, particularly in the field of bioethics. But if modern medicine regards human dignity as crucial, it tends to support this notion while assessing and measuring it. The quality of life becomes the gauge for measuring human dignity, starting from a distinction between a viable and a non-viable existence, which may eventually lead to assisted death, or to letting die. This article argues that the concept of quality of life is of great relevant for medical practice, but on the condition of not being used as a standard to measure the dignity of the individual. Rather, the quality of life should be regarded as an imperative posed by human dignity, which is necessarily intrinsic. If the quality of life measures dignity, humankind is divided into two categories: lives worthy of living, and lives unworthy of living, and society becomes a jungle. Raising the quality of life as a requirement of the inherent human dignity does not solve automatically all problems and does not eliminate a feeling of unworthiness. But it ensures its 'human' value: the equal respect for every human being.

The Baseline Values and Assumptions Document (BVAD) provides analysts, modelers, and other life support researchers with a common set of values and assumptions which can be used as a baseline in their studies. This baseline, in turn, provides a common point of origin from which many studies in the community may depart, making research results easier to compare and providing researchers with reasonable values to assume for areas outside their experience. With the ability to accurately compare different technologies' performance for the same function, managers will be able to make better decisions regarding technology development.

Apparent Half-Lives of Dioxins, Furans, and Polychlorinated Biphenyls as a Function of Age, Body Fat, Smoking Status, and Breast-Feeding

2009-01-01

Objective In this study we reviewed the half-life data in the literature for the 29 dioxin, furan, and polychlorinated biphenyl congeners named in the World Health Organization toxic equivalency factor scheme, with the aim of providing a reference value for the half-life of each congener in the human body and a method of half-life estimation that accounts for an individual’s personal characteristics. Data sources and extraction We compared data from > 30 studies containing congener-specific elimination rates. Half-life data were extracted and compiled into a summary table. We then created a subset of these data based on defined exclusionary criteria. Data synthesis We defined values for each congener that approximate the half-life in an infant and in an adult. A linear interpolation of these values was used to examine the relationship between half-life and age, percent body fat, and absolute body fat. We developed predictive equations based on these relationships and adjustments for individual characteristics. Conclusions The half-life of dioxins in the body can be predicted using a linear relationship with age adjusted for body fat, smoking, and breast-feeding. Data suggest an alternative method based on a linear relationship between half-life and total body fat, but this approach requires further testing and validation with individual measurements.

The value of human life in contemporary society. The global biography project.

Nary, G

1997-12-01

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.

Life satisfaction, QALYs, and the monetary value of health.

PubMed

Huang, Li; Frijters, Paul; Dalziel, Kim; Clarke, Philip

2018-06-18

The monetary value of a quality-adjusted life-year (QALY) is frequently used to assess the benefits of health interventions and inform funding decisions. However, there is little consensus on methods for the estimation of this monetary value. In this study, we use life satisfaction as an indicator of 'experienced utility', and estimate the dollar equivalent value of a QALY using a fixed effect model with instrumental variable estimators. Using a nationally-representative longitudinal survey including 28,347 individuals followed during 2002-2015 in Australia, we estimate that individual's willingness to pay for one QALY is approximately A$42,000-A$67,000, and the willingness to pay for not having a long-term condition approximately A$2000 per year. As the estimates are derived using population-level data and a wellbeing measurement of life satisfaction, the approach has the advantage of being socially inclusive and recognizes the significant meaning of people's subjective valuations of health. The method could be particularly useful for nations where QALY thresholds are not yet validated or established. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

Advanced Life Support Research and Technology Development Metric: Fiscal Year 2003

NASA Technical Reports Server (NTRS)

Hanford, A. J.

2004-01-01

This document provides the official calculation of the Advanced Life Support (ALS) Research and Technology Development Metric (the Metric) for Fiscal Year 2003. As such, the values herein are primarily based on Systems Integration, Modeling, and Analysis (SIMA) Element approved software tools or reviewed and approved reference documents. The Metric is one of several measures employed by the National Aeronautics and Space Administration (NASA) to assess the Agency s progress as mandated by the United States Congress and the Office of Management and Budget. Because any measure must have a reference point, whether explicitly defined or implied, the Metric is a comparison between a selected ALS Project life support system and an equivalently detailed life support system using technology from the Environmental Control and Life Support System (ECLSS) for the International Space Station (ISS). More specifically, the Metric is the ratio defined by the equivalent system mass (ESM) of a life support system for a specific mission using the ISS ECLSS technologies divided by the ESM for an equivalent life support system using the best ALS technologies. As defined, the Metric should increase in value as the ALS technologies become lighter, less power intensive, and require less volume. For Fiscal Year 2003, the Advanced Life Support Research and Technology Development Metric value is 1.47 for an Orbiting Research Facility and 1.36 for an Independent Exploration Mission.

The purpose of the study was to identify, describe and find the relationship among values taught, values learned, attitude and performance in mathematics. The researcher used descriptive-correlational method of research to gather information and to describe the nature of situation. The following instruments were used in this study: Math Attitude Inventory, Inventory of Values Taught and Learned which were content validated by experts in the field of Mathematics, Values and Education. Generally, most of the values were taught by the teachers. All of the values were learned by the students. The following got the highest mean ratings for values taught: moral strength, sharing, charity, valuing life, love of God, truth and honesty, reason, alternativism and articulation. The following got highest mean ratings for values learned: patience/tolerance, sharing, charity, valuing life, faith, love of God, truth and honesty, analogical thinking, confidence and individual liberty. Majority of the respondents have moderately positive attitude towards mathematics. Positive statements in the Mathematics Attitude Inventory are "Generally true" while negative statements are "Neutral." In conclusion, values were taught by mathematics teacher, thus, learned by the students. Therefore, mathematics is very much related to life. Values can be learned and strengthened through mathematics; there is a significant relationship between values taught by the teachers and values learned by the students and attitude towards mathematics and performance in mathematics; values taught does not affect attitude towards mathematics and performance in mathematics. A student may have a positive attitude towards mathematics or have an exemplary performance in mathematics even if the mathematics teacher did not teach values; values learned does not affect attitude towards mathematics and performance in mathematics. A student may have a positive attitude towards mathematics or have an exemplary performance in mathematics even he/she did not learned values in his/her mathematics class.

Health care economic analyses and value-based medicine.

PubMed

Brown, Melissa M; Brown, Gary C; Sharma, Sanjay; Landy, Jennifer

2003-01-01

Health care economic analyses are becoming increasingly important in the evaluation of health care interventions, including many within ophthalmology. Encompassed with the realm of health care economic studies are cost-benefit analysis, cost-effectiveness analysis, cost-minimization analysis, and cost-utility analysis. Cost-utility analysis is the most sophisticated form of economic analysis and typically incorporates utility values. Utility values measure the preference for a health state and range from 0.0 (death) to 1.0 (perfect health). When the change in utility measures conferred by a health care intervention is multiplied by the duration of the benefit, the number of quality-adjusted life-years (QALYs) gained from the intervention is ascertained. This methodology incorporates both the improvement in quality of life and/or length of life, or the value, occurring as a result of the intervention. This improvement in value can then be amalgamated with discounted costs to yield expenditures per quality-adjusted life-year ($/QALY) gained. $/QALY gained is a measure that allows a comparison of the patient-perceived value of virtually all health care interventions for the dollars expended. A review of the literature on health care economic analyses, with particular emphasis on cost-utility analysis, is included in the present review. It is anticipated that cost-utility analysis will play a major role in health care within the coming decade.

Broadening Participation in the Life Sciences with Social–Psychological Interventions

2016-01-01

Randomized controlled trials (RCTs) have recently documented the positive effects of social–psychological interventions on the performance and retention of underrepresented students in the life sciences. We review two types of social–psychological interventions that address either students’ well-being in college science courses or students’ engagement in science content. Interventions that have proven effective in RCTs in science courses (namely, utility-value [UV] and values-affirmation [VA] interventions) emphasize different types of student values—students’ perceptions of the value of curricular content and students’ personal values that shape their educational experiences. Both types of value can be leveraged to promote positive academic outcomes for underrepresented students. For example, recent work shows that brief writing interventions embedded in the curriculum can increase students’ perceptions of UV (the perceived importance or usefulness of a task for future goals) and dramatically improve the performance of first-generation (FG) underrepresented minority students in college biology. Other work has emphasized students’ personal values in brief essays written early in the semester. This VA intervention has been shown to close achievement gaps for women in physics classes and for FG students in college biology. By reviewing recent research, considering which interventions are most effective for different groups, and examining the causal mechanisms driving these positive effects, we hope to inform life sciences educators about the potential of social–psychological interventions for broadening participation in the life sciences.

To assess the impact of oral mucosa lesions on quality of life related to oral health (QLROH) and additionally to establish whether the etiopathogenicy of oral lesion is associated to the degree of QLROH impact. In this cross-sectional study performed on a non-probability sample of 247 consecutively patients attending the oral medicine and pathology clinic the Spanish version of Oral Health Impact Profile-49 questionnaire (OHIP-49-mx) was applied. Responses were recorded on Likert-type scale whose values ranged from 0 (never) to 4 (always). Values greater than the 50 percentile (median) were considered as indicative of poor quality of life. All patients were orally examined and diagnosed. In accordance to their etiopathogenicy 6 study groups were formed: 4 corresponded to MIND classification for diseases (Metabolic, Inflammatory, Neoplastic, and Development groups), with ≥2 diseases and no-lesion group. To identify possible differences of OHIP-49 values between study groups an ANOVA (one factor) parametric and a chi square tests were performed (SPSS®20.0). The OHIP-49-mx values were higher than the 50 percentile (established at 39) in metabolic, inflammatory, development, and ≥2 diseases groups, suggesting that this type of oral lesions negatively impact the quality of life. ≥2 diseasesgroup followed by metabolic and inflammatory diseases group (p 0.001) depicted worst quality of life. Functional limitation (p 0.003), pain, physical inability (p 0.001) and psychological disabilities dimensions exhibited greater values in all groups. Injured oral mucosa negatively impacts quality of life, specifically functional limitation, physical inability and psychological disabilities could lead to social isolation.To our knowledge, this is the first time that an association between QLROH and the etiopathogenicy of oral mucosal diseases is established.

With the method of space substituting time, the structure of Camellia rosthorniana populations in three forest communities, i.e., Jiant bamboo forest, coniferous and broad-leaved mixed forest, and evergreen broad-leaved forest in Mt. Jinyun was investigated, and based on static life-tables, the fecundity tables and reproductive value tables of C. rosthorniana populations were constructed. Each reproductive parameter and its relation to bionomic strategies of C. rosthorniana populations were also analyzed. The results indicated that in evergreen broad-leaved forest, C. rosthorniana population had the longest life span and the greatest fitness. The stage of maximum reproductive value increased with increasing stability of the community. The sum of each population's reproductive value, residual reproductive value and total reproductive value for the whole life-history of C. rosthorniana also increased with increasing maturity of the community, showing their inherent relationships with reproductive fitness. As regards to bionomic strategy, C. rosthorniana showed mainly the characteristics of a k-strategies, but in less stable community, the reproductive parameters were greatly changed, showing some characteristics of a r-strategies.

The Value of Medical and Pharmaceutical Interventions for Reducing Obesity

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.

Reference values of oxygen saturation (SpO2) to guide care of low birth weight neonates have been obtained mainly from Caucasians. Data from African newborns are lacking. To determine the pre- and post-ductal SpO2values of low birth weight neonates within the first 72 h of life, compare SpO2values of moderate-late preterm and term low birth weight neonates and determine how mode of delivery affected SpO2in the first 24 h of life. An observational descriptive study was carried out on apparently healthy low birth weight newborns weighing 1500 to ≤2499 g. Pre and post ductal SpO2values were recorded at the following hours of life: 10-24 h, >24-48 h and >48-72 h using a NONIN® pulse oximeter. The ranges of pre- and post-ductal SpO2in the study were similar for both preterm and term neonates in the study (89%-100%). The mean (standard deviation [SD]) pre-ductal SpO2was 95.9% (2.3) and the mean (SD) post-ductal SpO2was 95.9% (2.1). There was a significant increase in pre-ductal SpO2from 10 to 24 h through >48-72 h of life (P = 0.027). The mode of delivery did not affect SpO2values within 10-24 h of life. The present study documented daily single pre- and post-ductal SpO2 values for preterm and term low birth weight neonates weighing 1500 g to <2500 g during the first 72 h of life. The overall range and mean pre- and post-ductal SpO2 were similar for both categories of stable low birth weight neonates in the study. There was no significant difference between SpO2ranges for late preterm compared to term low birth weight neonates. The results obtained could serve as guide in assessing SpO2of low birth weight neonates weighing between 1500 and 2499 g in the first 72 h of life.

In this work, the half-life of the short-lived silver radionuclides {sup 108}Ag and {sup 110}Ag were measured by following the activity of samples after they were irradiated in the IEA-R1 reactor. 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 both the Normalized Residuals and the Rajeval techniques, in order to reach the most exact and precise final values. To check the validity of dead-time correction, a second correction method was also employed by means of counting a long-lived {sup 60}Co radioactive sourcemore » together with the samples as a livetime chronometer. The final half-live values obtained using both dead-time correction methods were in good agreement, showing that the correction was properly assessed.

[Value-based medicine in ophthalmology].

2006-06-01

Value-based medicine (VBM) unifies costs and patient-perceived value (improvement in quality of life, length of life, or both) of an intervention. Value-based ophthalmology is of increasing importance for decisions in eye care. The methods of VBM are explained and definitions for a specific terminology in this field are given. The cost-utility analysis as part of health care economic analyses is explained. VBM exceeds evidence-based medicine by incorporating parameters of cost and benefits from an ophthalmological intervention. The benefit of the intervention is defined as an increase or maintenance of visual quality of life and can be determined by utility analysis. The time trade-off method is valid and reliable for utility analysis. The resources expended for the value gained in VBM are measured with cost-utility analysis in terms of cost per quality-adjusted life years gained (euros/QALY). Numerous cost-utility analyses of different ophthalmological interventions have been published. The fundamental instrument of VBM is cost-utility analysis. The results in cost per QALY allow estimation of cost effectiveness of an ophthalmological intervention. Using the time trade-off method for utility analysis allows the comparison of ophthalmological cost-utility analyses with those of other medical interventions. VBM is important for individual medical decision making and for general health care.

Estimation of social value of statistical life using willingness-to-pay method in Nanjing, China.

Rational decision making regarding the safety related investment programs greatly depends on the economic valuation of traffic crashes. The primary objective of this study was to estimate the social value of statistical life in the city of Nanjing in China. A stated preference survey was conducted to investigate travelers' willingness to pay for traffic risk reduction. Face-to-face interviews were conducted at stations, shopping centers, schools, and parks in different districts in the urban area of Nanjing. The respondents were categorized into two groups, including motorists and non-motorists. Both the binary logit model and mixed logit model were developed for the two groups of people. The results revealed that the mixed logit model is superior to the fixed coefficient binary logit model. The factors that significantly affect people's willingness to pay for risk reduction include income, education, gender, age, drive age (for motorists), occupation, whether the charged fees were used to improve private vehicle equipment (for motorists), reduction in fatality rate, and change in travel cost. The Monte Carlo simulation method was used to generate the distribution of value of statistical life (VSL). Based on the mixed logit model, the VSL had a mean value of 3,729,493 RMB ($586,610) with a standard deviation of 2,181,592 RMB ($343,142) for motorists; and a mean of 3,281,283 RMB ($505,318) with a standard deviation of 2,376,975 RMB ($366,054) for non-motorists. Using the tax system to illustrate the contribution of different income groups to social funds, the social value of statistical life was estimated. The average social value of statistical life was found to be 7,184,406 RMB ($1,130,032). Copyright © 2016 Elsevier Ltd. All rights reserved.

Death, time and the theory of relativity.

PubMed

Chochinov, Harvey Max

2011-09-01

Many people believe that spending large amounts of money on end-of-life care is unjustified and even irrational. This fails to recognize that the value of time, particularly quality time, appears to increase as death draws near. Paying for treatment that merely allows patients and families to avoid confronting the inevitability of death is wrong. However, palliative care, which can bolster the quality of a patient's remaining days, provides benefits that extend to the family and beyond. How can the notion of time gaining value toward the end of life be incorporated into conventional cost-benefit analyses? A standard QALY (Quality Adjusted Life Years) is the product of quality of life and time, without adjusting for any change in the value of time. An additional variable--a Valuation Index (Palliative) (or VIP)--needs to be factored into the equation, providing a rational explanation for what otherwise might be deemed irrational spending. When one recognizes the multitude of important things that happen as people approach the very end of life, the numbers start to add up. Copyright © 2011 U.S. Cancer Pain Relief Committee.

2011-06-23

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. 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. 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. 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.

The main value orientations of medical students are directly or indirectly associated with various components of health. On the other hand, the knowledge of the predominating effect of life style on health, hazards of nicotine and alcohol did not become a persuasion in the majority of students, and high value of health did not transform into motivation forits preservation. That is why special attention in the training of physicians should be paid to the formation of practical habits of fundamentals of healthy life style. Healthy life style, an obligatory component of professional status of a physician, promotes a higher general cognitive activity of students and formation of persuasion of future doctors in their obligatory personal involvement in the solution of the problem of healthy life style of the entire population.

Karma yoga: A path towards work in positive psychology

PubMed Central

Kumar, Arun; Kumar, Sanjay

2013-01-01

Karma yoga is the path that leads to salvation through action. Salvation is the ultimate state of consciousness. Work is the central and defining characteristic of life. It may have intrinsic value, instrumental value, or both. Instrumental value includes incentive, dignity and power, etc., which is the result expected from the work. The Gita teaches us to do work without thinking of result (work with intrinsic value). Attachment with the result leads to stress, competition and aggression. Stress further gives rise to heart ailments, depression and suicide. Positive psychology studies the factors and conditions leading to pleasurable and satisfying life. Understanding Karma yoga and its practice has a similar role that lead an individual towards work and leading to a satisfied life. This may play a unique role towards practical aspects of positive psychology to improve one's lifestyle and aid in the treatment of stress disorders. PMID:23858246

The Math–Biology Values Instrument: Development of a Tool to Measure Life Science Majors’ Task Values of Using Math in the Context of Biology

PubMed Central

Andrews, Sarah E.; Runyon, Christopher; Aikens, Melissa L.

2017-01-01

In response to calls to improve the quantitative training of undergraduate biology students, there have been increased efforts to better integrate math into biology curricula. One challenge of such efforts is negative student attitudes toward math, which are thought to be particularly prevalent among biology students. According to theory, students’ personal values toward using math in a biological context will influence their achievement and behavioral outcomes, but a validated instrument is needed to determine this empirically. We developed the Math–Biology Values Instrument (MBVI), an 11-item college-level self-­report instrument grounded in expectancy-value theory, to measure life science students’ interest in using math to understand biology, the perceived usefulness of math to their life science career, and the cost of using math in biology courses. We used a process that integrates multiple forms of validity evidence to show that scores from the MBVI can be used as a valid measure of a student’s value of math in the context of biology. The MBVI can be used by instructors and researchers to help identify instructional strategies that influence math–biology values and understand how math–biology values are related to students’ achievement and decisions to pursue more advanced quantitative-based courses.

2018-04-01

In order to study the effect of titanium dioxide photocatalysis technology on the quality of kiwifruit during shelf life, the texture properties of kiwifruit during shelf life were measured by simulating the effect of cross-ripening among fruits and vegetables under the mixed environment of different fruits and vegetables. The results showed that the kiwifruit after photocatalytic preservation maintained a more mature state in the middle and preliminary stage of shelf life, chewiness is better than the control group and the blank group, compared with the over-ripen control group and low-maturity blank group, experimental group has the best commodity value. Therefore, using nanometer photocatalytic preservation can effectively reduce the ripening effect of kiwifruit in the mixed environment, control the after-ripening of kiwifruit, and meanwhile maintain the commodity value of the kiwifruit during the shelf life.iO2, Photocatalysis, Kiwifruit, Shelf-life.

Rodriguez Mosquera, Patricia M; Imada, Toshie

2013-01-01

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

The Metric is one of several measures employed by the NASA to assess the Agency s progress as mandated by the United States Congress and the Office of Management and Budget. Because any measure must have a reference point, whether explicitly defined or implied, the Metric is a comparison between a selected ALS Project life support system and an equivalently detailed life support system using technology from the Environmental Control and Life Support System (ECLSS) for the International Space Station (ISS). This document provides the official calculation of the Advanced Life Support (ALS) Research and Technology Development Metric (the Metric) for Fiscal Year 2004. The values are primarily based on Systems Integration, Modeling, and Analysis (SIMA) Element approved software tools or reviewed and approved reference documents. For Fiscal Year 2004, the Advanced Life Support Research and Technology Development Metric value is 2.03 for an Orbiting Research Facility and 1.62 for an Independent Exploration Mission.

Outcome of children with nephrotic syndrome has continued to improve over time. However minimal data exist to describe health-related quality of life in children with nephrotic syndrome. This cross sectional study was conducted over a period of six months to assess the health related quality of life in children with nephrotic syndrome in the Department of Pediatric Nephrology, Dhaka Medical College Hospital, Bangladesh. Fifty children (age ranged 2-12 years) with nephrotic syndrome who had three or more relapses diagnosed at least one year back receiving treatment and on follow up were included in this study. Quality of Life scores were collected using Bengali translated instruments- the Pediatric Quality of Life Inventory™ (PedsQL™) version 4.0 Generic Scale and the Pediatric Quality of Life Questionnaire for Nephrotic Syndrome proxy-report from parents. Medical data and Demographic data were collected from medical records, and from parents in outpatient department or hospital ward. Interviews of eligible guardians were performed individually to collect quality of life (QoL) scores. Among 50 children, mean±SD age of the children was 7±2.92 years. Most children were male (58%). Female parents respondent during interview were 62%, most parents (48%) were very poor in socioeconomic condition. Most children had frequent relapses (60%). Median time since diagnosis was 2 years. Regarding PedsQL scores, child age with physical summary score (p value <0.001), child age with social summary score (p value 0.003), frequent relapse with kidney disease summary score (p value 0.04) and time since diagnosis (p value <0.001) were statistically significant. In conclusion physical and social summary score were worst. Frequent relapse found to be an important factor in impaired QoL. Prolonged duration of the disease activity was associated with significant impairment of QoL.

Gamma-ray bursts (GRBs) are copious sources of gamma rays whose interaction with a planetary atmosphere can pose a threat to complex life. Using recent determinations of their rate and probability of causing massive extinction, we explore what types of universes are most likely to harbor advanced forms of life. We use cosmological N-body simulations to determine at what time and for what value of the cosmological constant (Λ) the chances of life being unaffected by cosmic explosions are maximized. Life survival to GRBs favors Lambda-dominated universes. Within a cold dark matter model with a cosmological constant, the likelihood of life survival to GRBs is governed by the value of Λ and the age of the Universe. We find that we seem to live in a favorable point in this parameter space that minimizes the exposure to cosmic explosions, yet maximizes the number of main sequence (hydrogen-burning) stars around which advanced life forms can exist.

The Math-Biology Values Instrument: Development of a Tool to Measure Life Science Majors' Task Values of Using Math in the Context of Biology.

PubMed

Andrews, Sarah E; Runyon, Christopher; Aikens, Melissa L

2017-01-01

In response to calls to improve the quantitative training of undergraduate biology students, there have been increased efforts to better integrate math into biology curricula. One challenge of such efforts is negative student attitudes toward math, which are thought to be particularly prevalent among biology students. According to theory, students' personal values toward using math in a biological context will influence their achievement and behavioral outcomes, but a validated instrument is needed to determine this empirically. We developed the Math-Biology Values Instrument (MBVI), an 11-item college-level self--report instrument grounded in expectancy-value theory, to measure life science students' interest in using math to understand biology, the perceived usefulness of math to their life science career, and the cost of using math in biology courses. We used a process that integrates multiple forms of validity evidence to show that scores from the MBVI can be used as a valid measure of a student's value of math in the context of biology. The MBVI can be used by instructors and researchers to help identify instructional strategies that influence math-biology values and understand how math-biology values are related to students' achievement and decisions to pursue more advanced quantitative-based courses. © 2017 S.

The Arrhenius model of the shelf life prediction which based on the TBARS index was established in this study. The results showed that the significant changed of AV, POV, COV and TBARS with temperature increased, and the reaction rate constants k was obtained by the first order reaction kinetics model. Then the secondary model fitting was based on the Arrhenius equation. There was the optimal fitting accuracy of TBARS in the first and the secondary model fitting (R2≥0.95). The verification test indicated that the relative error between the shelf life model prediction value and actual value was within ±10%, suggesting the model could predict the shelf life of surimi cake.

The value-based medicine comparative effectiveness and cost-effectiveness of penetrating keratoplasty for keratoconus.

Roe, Richard H; Lass, Jonathan H; Brown, Gary C; Brown, Melissa M

2008-10-01

To perform a base case, comparative effectiveness, and cost-effectiveness (cost-utility) analysis of penetrating keratoplasty for patients with severe keratoconus. Visual acuity data were obtained from a large, retrospective multicenter study in which patients with keratoconus with less than 20/40 best corrected visual acuity and/or the inability to wear contact lenses underwent penetrating keratoplasty, with an average follow-up of 2.1 years. The results were combined with other retrospective studies investigating complication rates of penetrating keratoplasty. The data were then incorporated into a cost-utility model using patient preference-based, time trade-off utilities, computer-based decision analysis, and a net present value model to account for the time value of outcomes and money. The comparative effectiveness of the intervention is expressed in quality-of-life gain and QALYs (quality-adjusted life-years), and the cost-effectiveness results are expressed in the outcome of $/QALY (dollars spent per QALY). Penetrating keratoplasty in 1 eye for patients with severe keratoconus results in a comparative effectiveness (value gain) of 16.5% improvement in quality of life every day over the 44-year life expectancy of the average patient with severe keratoconus. Discounting the total value gain of 5.36 QALYs at a 3% annual discount rate yields 3.05 QALYs gained. The incremental cost for penetrating keratoplasty, including all complications, is $5934 ($5913 discounted at 3% per year). Thus, the incremental cost-utility (discounted at 3% annually) for this intervention is $5913/3.05 QALYs = $1942/QALY. If both eyes undergo corneal transplant, the total discounted value gain is 30% and the overall cost-utility is $2003. Surgery on the second eye confers a total discounted value gain of 2.5 QALYs, yielding a quality-of-life gain of 11.6% and a discounted cost-utility of $2238/QALY. Penetrating keratoplasty for patients with severe keratoconus seems to be a comparatively effective and cost-effective procedure when compared with other interventions across different medical specialties.

[Relation between personality traits and personal values in cocaine-dependent patients].

Saiz, Jesús; Álvaro, José Luis; Martínez, Isabel

2011-01-01

To describe the relationship between personal values and personality traits in cocaine-using patients and analyze their specificity in the explanation of different types of constructs. A study was carried out to explore the association between these variables in a group of 230 patients receiving treatment for cocaine dependence. The Portrait Values Questionnaire was used for measuring personal values, while the Big-Five Factors Questionnaire was used to measure personality traits. In addition, we explored the relationship of values and traits with the variables "degree of satisfaction with life" (life satisfaction) and "belonging to a religious association" (religiosity). A significant association was found between personal values and personality traits. At the same time, their conceptual and empirical differences were revealed, as it was demonstrated that personal values better explain "belonging to a religious association", whilst personality traits better explain "degree of satisfaction with life". Thus, it was found that personal values better explain behaviours that depend on greater cognitive control, while personality traits would have more influence on tendencies and behaviours that are subject to lower cognitive control levels. Considering the relationship between the two constructs, and given that cocaine use is associated with both high and low cognitive control, in explanations of cocaine use it would be appropriate to take into account the explanatory contribution of personal values and personality traits in a complementary way.

Does the working environment influence health care professionals' values, meaning in life and religiousness? Palliative care units compared with maternity wards.

2014-11-01

Increased altruism, self-transcendence, and quests for meaning in life (MiL) have been found in palliative care (PC) patients and their families who experience the finiteness of life. Similar changes were observed in healthy subjects who were experimentally confronted with their mortality. The study investigated how daily experiences of the transitoriness of life influence PC health care professionals' (HCPs) values, MiL, and religiousness. In a cross-sectional study, the Schwartz Value Survey, the Schedule for Meaning in Life Evaluation, and the Idler Index of Religiosity were used to investigate personal values, MiL, and private religiousness. HCPs working in PC (confronted with death) were compared with a control group of HCPs working at maternity wards (MWs) using multivariate models. Differences were considered to be statistically significant at P < 0.05. Seventy PC- and 70 MW-HCPs took part in the study (response rate 74.0%). No differences between the groups were found in overall MiL satisfaction scores. PC-HCPs were significantly more religious than MW-HCPs; they listed spirituality and nature experience more often as areas in which they experience MiL. Furthermore, hedonism was more important for PC-HCPs, and they had higher scores in openness-to-change values (stimulation and self-direction). MW-HCPs were more likely to list family as a MiL area. They assigned more importance to health and scored higher in conservation values (conformity and security). Duration of professional experience did not influence these results. Basic differences in values, MiL, and religiousness between PC-HCPs and MW-HCPs might have influenced the choice of working environment because no effect of job duration was observed. Longitudinal research is needed to confirm this hypothesis. Copyright © 2014 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc. All rights reserved.

Value priorities and their relations with quality of life in the Baby Boomer generation of Lithuanian nurses: a cross-sectional survey.

2007-11-08

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. 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 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. 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.

2018-06-08

International migration is an important issue for many high-income countries and is accompanied by opportunities as well as challenges. South Asians are the largest minority ethnic group in the United Kingdom, and this diaspora is reflective of the growing diversity of British society. An empirical study was performed to ascertain the faith-based values, beliefs, views and attitudes of participants in relation to their perception of issues pertaining to end-of-life care. Empirical observations from this study, as well as the extant knowledge-base from the literature, are used to support and contextualise our reflections against a socio-legal backdrop. We argue for accommodation of faith-based values of migrants at end-of-life within normative structures of receiving countries. We posit the ethically relevant principles of inclusiveness, integration and embedment, for an innovative bioethical framework as a vehicle for accommodating faith-based values and needs of migrants at end-of-life. These tenets work conjunctively, as well as individually, in respect of individual care, enabling processes and procedures, and ultimately for formulating policy and strategy. © 2018 John Wiley & Sons Ltd.

Value-Based Medicine and Pharmacoeconomics.

PubMed

Brown, Gary C; Brown, Melissa M

2016-01-01

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

In most mirror decays used for these tests, uncertainties in the f t values are dominated by the uncertainties in the half-lives. Purpose: Two precision half-life measurements were performed for the T =1 /2 β+ emitters, 17F and 33Cl, in order to eliminate the half-life as the leading source of uncertainty in their f t values. Method: Half-lives of 17F and 33Cl were determined using β counting of implanted radioactive ion beam samples on a moving tape transport system at the Système de Production d'Ions Radioactifs Accélérés en Ligne low-energy identification station at the Grand Accélérateur National d'Ions Lourds. Results: The 17F half-life result, 64.347 (35) s, precise to ±0.05 % , is a factor of 5 times more precise than the previous world average. The half-life of 33Cl was determined to be 2.5038 (22) s. The current precision of ±0.09 % is nearly 2 times more precise compared to the previous world average. Conclusions: The precision achieved during the present measurements implies that the half-life no longer dominates the uncertainty of the f t values for both T =1 /2 mirror decays 17F and 33Cl.

The aim of this research was to understand the characteristics of rural young suicides with major depression in China and the relationship of these events with Confucian values and negative life events. Our cases were 90 rural suicides with major depression with victims aged 15 to 34 years and living matched controls of the same gender, age (within 3 years), and county of residence. Confucian values appear to be a protective factor for men but a risk factor for women with regard to suicide with major depression. More attention should be paid to Confucian values in suicide prevention efforts.

Introduction The incremental cost-effectiveness ratio (ICER) is typically compared with a reference value to support the cost-effectiveness of a decision. One method for estimating this value is to estimate the willingness-to-pay (WTP) for a quality-adjusted life-year (QALY). This study was conducted to explore the WTP for a QALY in the Malaysian population. Methods A cross-sectional, contingent valuation study was conducted in Penang, Malaysia. Respondents were selected from randomly chosen geographical grids of Penang. Respondents’ sociodemographic information, qualities of life, and WTP for one additional QALY were collected using predesigned questionnaires in face-to-face interviews. WTP values were elicited using a double-bound dichotomous choice via a bidding game approach. The Heckman selection model was applied to the analysis of the mean WTP/QALY values, where the “protest zero” values, which may contribute to selection bias, were excluded. Results The mean value of WTP for an additional QALY gained was estimated to be MYR (Malaysian Ringgit) 29,080 (~USD 9,000). Key factors that affected the WTP include ethnicity and estimated monthly household income. Conclusion The study findings suggested that the cost-effectiveness threshold value as studied in Penang, Malaysia was estimated to be MYR 29,080. PMID:25364267

Previous experience has shown that school-based taekwondo training in the United States (US) results in many beneficial effect sregarding school education and the physical health of the adolescent participants; of especial significance, the training plays an important role in terms of exercise value and school-life adaptation. To explore this overall effect, a self-administered questionnaire was distributed to 401 adolescents over the age of 10 years. The survey comprisesa total of 29 questions that consist of 17 exercise-value-related questions (general, moral, and status) and 12 questions that are related to school-life adaptation (adaptation to teachers, adaptation to academic activities, adaptation to rule compliance, and adaptation to school activities). The survey results show that taekwondo training affects school-life adaptation by helping to improve student morality and by bolstering the students compliance with school rules during their schooling. The exercise value of taekwondo training is considered a necessity for US adolescents due to the corresponding educational aspects; in particular, the training plays a very important role in the maintenance of amenable student-teacher and student-peer relationships. From the previously mentioned findings, and if taekwondo teachers train their students carefully with educational missions in mind, it is expected that taekwondo training will play a very important role in the cultivation of anappropriate education value among US adolescents.

Uchida, S.; Muramatsu, Y.; Sumiya, M.

In order to obtain the biological half-life (Tb) of iodine deposited on rough rice grains, rice plants of four different growing stages--heading, milky, dough, and yellow ripe--were exposed to elemental gaseous iodine. After the exposure, the rough rice samples were collected at different intervals and analyzed for iodine to estimate the value of Tb. The average value of Tb obtained by the experiments at the dough and yellow ripe stages was about 200 d. This value is considerably larger than those for pasture grass and leafy vegetables.

The effect of compost-amendment and moisture status on the persistence of azoxystrobin [methyl (E)-2-{2-(6-(2-cyanophenoxy) pyrimidin-4-yloxy) phenyl}-3-methoxyacrylate], a strobilurin fungicide, in two rice-growing soils was studied. Azoxystrobin is more sorbed in the silt loam (K f – 4.66) soil than the sandy loam (K f – 2.98) soil. Compost-amendment at 5 % levels further enhanced the azoxystrobin sorption and the respective Kf values in silt loam and sandy loam soils were 8.48 and 7.6. Azoxystrobin was more persistent in the sandy loam soil than the silt loam soil. The half–life values of azoxystrobin in nonflooded and flooded silt loam soil were 54.7 and 46.3 days, respectively. The corresponding half–life values in the sandy loam soils were 64 and 62.7 days, respectively. Compost application enhanced persistence of azoxystrobin in the silt loam soil under both moisture regimes and half-life values in non–flooded and flooded soils were 115.7 and 52.8 days, respectively. However, compost enhanced azoxystrobin degradation in the sandy loam soil and half-life values were 59 (nonflooded) and 54.7 days (flooded). The study indicates that compost amendment enhanced azoxystrobin sorption in the soils. Azoxystrobin is more persistent in non-flooded soils than the flooded soils. Compost applications to soils had mixed effect on the azoxystrobin degradation.

The application of value-based medicine (VBM) tenets in the area of glaucoma research requires valid and reliable data concerning the quality of life with glaucoma. A multitude of instruments for measuring quality of life of patients with glaucoma have been employed in the past. Any instrument used would need to capture peripheral vision loss and its influence on patient-reported quality of life as this is one of the hallmarks of this disease. Cost-utility analyses can then be based on the reported quality of life and the cost of glaucoma therapy. Several cost-utility analyses have been applied in the field of glaucoma screening as well as treating ocular hypertension and based on this a recommendation regarding population subgroups which can be treated cost efficiently can be made.

Background Little guidance is available for health care providers who try to communicate with patients and their families in a culturally sensitive way about end-of-life care. Objective To explore the content and structure of end-of-life discussions that would optimize decision making by conducting focus groups with two diverse groups of patients that vary in ethnicity and socioeconomic status. Design Six focus groups were conducted; 3 included non-Hispanic white patients recruited from a University hospital (non-Hispanic white groups) and 3 included African-American patients recruited from a municipal hospital (African-American groups). A hypothetical scenario of a dying relative was used to explore preferences for the content and structure of communication. Participants Thirty-six non-Hispanic white participants and 34 African-American participants. Approach Content analysis of focus group transcripts. Results Non-Hispanic white participants were more exclusive when recommending family participants in end-of-life discussions while African-American participants preferred to include more family, friends and spiritual leaders. Requested content varied as non-Hispanic white participants desired more information about medical options and cost implications while African-American participants requested spiritually focused information. Underlying values also differed as non-Hispanic white participants expressed more concern with quality of life while African-American participants tended to value the protection of life at all costs. Conclusions The groups differed broadly in their preferences for both the content and structure of end-of-life discussions and on the values that influence those preferences. Further research is necessary to help practitioners engage in culturally sensitive end-of-life discussions with patients and their families by considering varying preferences for the goals of end-of-life care communication.

Lee, Yew Kong; Low, Wah Yun; Ng, Chirk Jenn

2013-01-01

Patient decisions are influenced by their personal values. However, there is a lack of clarity and attention on the concept of patient values in the clinical context despite clear emphasis on patient values in evidence-based medicine and shared decision making. The aim of the study was to explore the concept of patient values in the context of making decisions about insulin initiation among people with type 2 diabetes. We conducted individual in-depth interviews with people with type 2 diabetes who were making decisions about insulin treatment. Participants were selected purposively to achieve maximum variation. A semi-structured topic guide was used to guide the interviews which were audio-recorded and analysed using a thematic approach. We interviewed 21 participants between January 2011 and March 2012. The age range of participants was 28-67 years old. Our sample comprised 9 women and 12 men. Three main themes, 'treatment-specific values', 'life goals and philosophies', and 'personal and social background', emerged from the analysis. The patients reported a variety of insulin-specific values, which were negative and/or positive beliefs about insulin. They framed insulin according to their priorities and philosophies in life. Patients' decisions were influenced by sociocultural (e.g. religious background) and personal backgrounds (e.g. family situations). This study highlighted the need for expanding the current concept of patient values in medical decision making. Clinicians should address more than just values related to treatment options. Patient values should include patients' priorities, life philosophy and their background. Current decision support tools, such as patient decision aids, should consider these new dimensions when clarifying patient values.

A cross-sectional study investigated changes in patients' value systems following a diagnosis of cancer. Fifty patients at 1 to 6 months following cancer diagnosis, were asked to compare their current values with their recollection of past values. Using the Rokeach Value Survey we obtained statistically significant results showing that twenty-seven out of thirty-six values changed their importance from the patients' perspective: 16 values significantly increased, while 11 values significantly decreased in importance. Changes with respect to nine values were insignificant. We indentified clusters of values increasing in importance the most: Religious morality (Salvation, Forgiving, Helpful, Clean), Personal orientation (Self-Respect, True Friendship, Happiness), Self-constriction (Self-Controlled, Obedient, Honest), Family security (Family Security, Responsible), and Delayed gratification (Wisdom, Inner Harmony). We also observed that the following value clusters decreased in importance: Immediate gratification (An Exciting Life, Pleasure, A Comfortable Life); Self-expansion (Capable, Ambitious, Broadminded), Competence (A Sense of Accomplishment, Imaginative, Intellectual). The remaining values belonged to clusters that as a group changed slightly or not at all. Practical implications of the study are discussed.

To assess the value conferred by photodynamic therapy (PDT) and the cost-utility of PDT for the treatment of classic, subfoveal choroidal neovascularization associated with age-related macular degeneration (ARMD). Average cost-utility analysis utilizing clinical trial data, patient-based time tradeoff utility preferences, and a third party insurer cost perspective. Five-year visual acuity data from the TAP (Treatment of Age-related Macular Degeneration With Photodynamic Therapy) Investigation were modeled into a 12-year, value-based, reference case, cost-utility model utilizing year 2004 Medicare costs and an outcome of dollar/QALY (dollars/quality-adjusted life-year). Discounting of outcomes and costs using net present value analysis with a 3% annual rate was performed as recommended by the Panel for Cost-Effectiveness in Health and Medicine. PDT with verteporfin (Visudyne) dye for classic subfoveal choroidal neovascularization confers an 8.1% quality of life (value) improvement over the 12-year life expectancy of the reference case, while during the last 8 years the value improvement is 9.5%. The average cost-utility of the intervention is dollar 31,103/QALY (quality-adjusted life-year). Extensive one-way sensitivity analysis values range from dollar 20,736/QALY if treatment efficacy is increased by 50% to dollar 62,207 if treatment efficacy is decreased by 50%, indicating robustness of the model. PDT using verteporfin dye to treat classic subfoveal choroidal neovascularization is a very cost-effective treatment by conventional standards. The marked improvement in cost-effectiveness compared with a previous report results from the facts that the treatment benefit increasingly accrues during 5 years of follow-up while the number of yearly treatments diminishes markedly during that time.

Background The results of recent studies suggest the usefulness of PCT for early diagnosis of neonatal sepsis, with varying results. The aim of this prospective multicenter study was to determine the behavior of serum PCT concentrations in both uninfected and infected neonates, and to assess the value of this marker for diagnosis of neonatal sepsis of vertical transmission. Methods PCT was measured in 827 blood samples collected prospectively from 317 neonates admitted to 13 acute-care teaching hospitals in Spain over one year. Serum PCT concentrations were determined by a specific immunoluminometric assay. The diagnostic efficacy of PCT at birth and within 12–24 h and 36–48 h of life was evaluated calculating the sensitivity, specificity, and likelihood ratio of positive and negative results. Results 169 asymptomatic newborns and 148 symptomatic newborns (confirmed vertical sepsis: 31, vertical clinical sepsis: 38, non-infectious diseases: 79) were studied. In asymptomatic neonates, PCT values at 12–24 h were significantly higher than at birth and at 36–48 h of life. Resuscitation at birth and chorioamnionitis were independently associated to PCT values. Neonates with confirmed vertical sepsis showed significantly higher PCT values than those with clinical sepsis. PCT thresholds for the diagnosis of sepsis were 0.55 ng/mL at birth (sensitivity 75.4%, specificity 72.3%); 4.7 ng/mL within 12–24 h of life (sensitivity 73.8%, specificity 80.8%); and 1.7 ng/mL within 36–48 h of life (sensitivity 77.6%, specificity 79.2%). Conclusion Serum PCT was moderately useful for the detection of sepsis of vertical transmission, and its reliability as a maker of bacterial infection requires specific cutoff values for each evaluation point over the first 48 h of life.

A potential gender bias in assessing quality of life - a standard gamble experiment among university students.

PubMed

Obaidi, Leath Al; Mahlich, Jörg

2015-01-01

There are several methodologies that can be used for evaluating patients' perception of their quality of life. Most commonly, utilities are directly elicited by means of either the time-trade-off or the standard-gamble method. In both methods, risk attitudes determine the quality of life values. Quality of life values among 31 Austrian undergraduate students were elicited by means of the standard gamble approach. The impact of several variables such as gender, side job, length of study, and living arrangements on the quality of life were identified using different types of regression techniques (ordinary least squares, generalized linear model, Betafit). Significant evidence was found that females are associated with a higher quality of life in all specifications of our estimations. The observed gender differences in quality of life can be attributed to a higher degree of risk aversion of women. A higher risk aversion leads to a higher valuation of given health states and a potential gender bias in health economic evaluations. This result could have implications for health policy planners when it comes to budget allocation decisions.

Productive activity and life satisfaction in Korean elderly women.

PubMed

Kim, Ju-Hyun

2013-01-01

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

Who should be saved when health resources are limited? Although bioethicists and policymakers continue to debate which metric should be used to evaluate health interventions, public policy is also subject to public opinion. We investigated how the public values life when evaluating vaccine-allocation policies during a flu epidemic. We found that people's ratings of the acceptability of policies were dramatically influenced by question framing. When policies were described in terms of lives saved, people judged them on the basis of the number of life years gained. In contrast, when the policies were described in terms of lives lost, people considered the age of the policy's beneficiaries, taking into account the number of years lived to prioritize young targets for the health intervention. In addition, young targets were judged as more valuable in general, but young participants valued young targets even more than older participants did.

Background: Highly active antiretroviral therapy regimens have resulted in the systemic/clinical healing for human immune deficiency virus-infected patients but the consequence of antiretroviral therapy on the whole quality of life has become a major concern. The current study correlates the relationship of quality of life with successful highly active antiretroviral therapy. Aim: To determine the health-related quality of life in human immune deficiency virus-infected patients on highly active anti-retroviral therapy regimen in tribal region of Chhattisgarh. Design: An open label prospective study. Materials and Methods: Health-related quality of life was assessed using a standardized questionnaire, the Medical Outcomes Survey Short Form 36. Physical health summary scores and mental health summary scores were compared of pre-Highly Active Anti-Retroviral Therapy (at baseline) and post 12 months of therapy. Results: The increase in CD4 cell counts was extremely significant (P < 0.0001). The Physical Composite Summary (P value = 0.0003) improved significantly, whereas the Mental Composite Summary (with a baseline value of 40.7), post 12 months, was calculated as 42.8 (P value = 0.2371) and was statistically not significant. Conclusion: Efficacy measurement is the key ingredient of highly active anti-retroviral therapy, which must also include assessment of health-related quality of life to maximize the holistic approach towards disease.

Vegetarian nutrition is gaining increasing public attention worldwide. While some studies have examined differences in motivations and personality traits between vegetarians and omnivores, only few studies have considered differences in motivations and personality traits between the 2 largest vegetarian subgroups: lacto-ovo-vegetarians and vegans. To examine differences between lacto-ovo-vegetarians and vegans in the distribution patterns of motives, values, empathy, and personality profiles. An anonymous online survey was performed in January 2014. Group differences between vegetarians and vegans in their initial motives for the choice of nutritional approaches, health-related quality of life (World Health Organization Quality of Life-BREF (WHOQOL-BREF)), personality traits (Big Five Inventory-SOEP (BFI-S)), values (Portraits Value Questionnaire (PVQ)), and empathy (Empathizing Scale) were analyzed by univariate analyses of covariance; P values were adjusted for multiple testing. 10,184 individuals completed the survey; 4,427 (43.5%) were vegetarians and 4,822 (47.3%) were vegans. Regarding the initial motives for the choice of nutritional approaches, vegans rated food taste, love of animals, and global/humanitarian reasons as more important, and the influence of their social environment as less important than did vegetarians. Compared to vegetarians, vegans had higher values on physical, psychological, and social quality of life on the WHOQOL-BREF, and scored lower on neuroticism and higher on openness on the BFI-S. In the PVQ, vegans scored lower than vegetarians on power/might, achievement, safety, conformity, and tradition and higher on self-determination and universalism. Vegans had higher empathy than vegetarians (all p < 0.001). This survey suggests that vegans have more open and compatible personality traits, are more universalistic, empathic, and ethically oriented, and have a slightly higher quality of life when compared to vegetarians. Given the small absolute size of these differences, further research is needed to evaluate whether these group differences are relevant in everyday life and can be confirmed in other populations. © 2016 S.

Did people "buy" what was "sold"? A qualitative evaluation of a contingent valuation survey information set for gains in life expectancy.

PubMed

Baker, R; Bartczak, A; Chilton, S; Metcalf, H

2014-01-15

A number of stated preferences studies have estimated a monetary value for the gains in life expectancy resulting from pollution control, using a Value of a Life Year (VOLY) approach. However, life expectancy gains are a complex concept and no attempt has been made, to date, to investigate peoples' understanding of what it is they are being asked to value. Past practice has been to focus on the outcome of a policy i.e. a gain to the average person of X months', providing no details on how the individual receives, or experiences this gain, a potentially important attribute to value. This paper sets up and reports the results from a structured debriefing exercise to qualitatively investigate an alternative approach which explicitly emphasises how this gain is delivered (on-going reductions in the risk of death). We find that, for the majority of respondents, the approach is effective in communicating the on-going nature of the gain and reduces or eliminates the use of the (incorrect) heuristic that it is an 'add-on' at the end of life, in poor health. Further refinements are required, however, to communicate the cumulative nature of these risk reductions and the lack of impact on quality of life. The lesson for stated preference studies in general is that structured debriefings can be very useful, highlighting such issues as the persistence of ill-defined attributes and the difficulties that respondents may encounter setting aside their preferences over attributes of the good that should not be included in the valuation.

Life-cycle assessment is usually based on regular discharges that occur at a more or less constant rate. Nevertheless, the more factors that are taken into account in the LCA the better picture it gives on the environmental aspects of a product. In this study an approach to incorporate accidental releases into a products` life-cycle assessment was developed. In this approach accidental releases are divided into two categories. The first category consists of those unplanned releases which occur with a predicted level and frequency. Due to the high frequency and small release size at a time, these accidental releases can bemore » compared to continuous emissions. Their global impacts are studied in this approach. Accidental releases of the second category are sudden, unplanned releases caused by exceptional situations, e.g. technical failure, action error or disturbances in process conditions. These releases have a singular character and local impacts are typical of them. As far as the accidental releases of the second category are concerned, the approach introduced in this study results in a risk value for every stage of a life-cycle, the sum of which is a risk value for the whole life-cycle. Risk value is based on occurrence frequencies of incidents and potential environmental damage caused by releases. Risk value illustrates the level of potential damage caused by accidental releases related to the system under study and is meant to be used for comparison of these levels of two different products.

Blood, sweat and plaster casts: Reviewing the history, composition, and scientific value of the Raymond A. Dart Collection of African Life and Death Masks.

PubMed

Houlton, T M R; Billings, B K

2017-10-01

This paper addresses the history, composition and scientific value of one of the most comprehensive facemask collections in Africa, the Raymond A. Dart Collection of African Life and Death Masks. Housed within the School of Anatomical Sciences at the University of the Witwatersrand (South Africa), it comprises 1110 masks (397 life, 487 death, 226 unknown). Life masks represent populations throughout Africa; death masks predominately southern Africa. Males preponderate by 75%. Recorded ages are error prone, but suggest most life masks are those of <35 year-olds, death masks of 36+ year-olds. A total of 241 masks have associated skeletons, 209 presenting a complete skull. Life masks date between 1927 and c.1980s, death masks 1933 and 1963. This historical collection presents uncanny associations with outmoded typological and evolutionary theories. Once perceived an essential scientific resource, performed craniofacial superimpositions identify the nose as the only stable feature maintained, with the remaining face best preserved in young individuals with minimal body fat. The facemask collection is most viable for teaching and research within the history of science, specifically physical anthropology, and presents some value to craniofacial identification. Future research will have to be conducted with appropriate ethical considerations to science and medicine. Copyright © 2017 Elsevier GmbH. All rights reserved.

The goal of value-based medicine analyses: comparability. The case for neovascular macular degeneration.

To evaluate the comparability of articles in the peer-reviewed literature assessing the (1) patient value and (2) cost-utility (cost-effectiveness) associated with interventions for neovascular age-related macular degeneration (ARMD). A search was performed in the National Library of Medicine database of 16 million peer-reviewed articles using the key words cost-utility, cost-effectiveness, value, verteporfin, pegaptanib, laser photocoagulation, ranibizumab, and therapy. All articles that used an outcome of quality-adjusted life-years (QALYs) were studied in regard to (1) percent improvement in quality of life, (2) utility methodology, (3) utility respondents, (4) types of costs included (eg, direct healthcare, direct nonhealthcare, indirect), (5) cost bases (eg, Medicare, National Health Service in the United Kingdom), and (6) study cost perspective (eg, government, societal, third-party insurer). To qualify as a value-based medicine analysis, the patient value had to be measured using the outcome of the QALYs conferred by respective interventions. As with value-based medicine analyses, patient-based time tradeoff utility analysis had to be utilized, patient utility respondents were necessary, and direct medical costs were used. Among 21 cost-utility analyses performed on interventions for neovascular macular degeneration, 15 (71%) met value-based medicine criteria. The 6 others (29%) were not comparable owing to (1) varying utility methodology, (2) varying utility respondents, (3) differing costs utilized, (4) differing cost bases, and (5) varying study perspectives. Among value-based medicine studies, laser photocoagulation confers a 4.4% value gain (improvement in quality of life) for the treatment of classic subfoveal choroidal neovascularization. Intravitreal pegaptanib confers a 5.9% value gain (improvement in quality of life) for classic, minimally classic, and occult subfoveal choroidal neovascularization, and photodynamic therapy with verteporfin confers a 7.8% to 10.7% value gain for the treatment of classic subfoveal choroidal neovascularization. Intravitreal ranibizumab therapy confers greater than a 15% value gain for the treatment of subfoveal occult and minimally classic subfoveal choroidal neovascularization. The majority of cost-utility studies performed on interventions for neovascular macular degeneration are value-based medicine studies and thus are comparable. Value-based analyses of neovascular ARMD monotherapies demonstrate the power of value-based medicine to improve quality of care and concurrently maximize the efficacy of healthcare resource use in public policy. The comparability of value-based medicine cost-utility analyses has important implications for overall practice standards and public policy. The adoption of value-based medicine standards can greatly facilitate the goal of higher-quality care and maximize the best use of healthcare funds.

2017-04-01

Cost-effectiveness analyses often inform healthcare reimbursement decisions. The preferred measure of effectiveness is the quality adjusted life year (QALY) gained, where the quality of life adjustment is measured in terms of utility. Areas covered: We assessed the availability and variation of utility values for health states associated with advanced or metastatic non-small cell lung cancer (NSCLC) to identify values appropriate for cost-effectiveness models assessing alternative treatments. Our systematic search of six electronic databases (January 2000 to August 2015) found the current literature to be sparse in terms of utility values associated with NSCLC, identifying 27 studies. Utility values were most frequently reported over time and by treatment type, and less frequently by disease response, stage of disease, adverse events or disease comorbidities. Expert commentary: In response to rising healthcare costs, payers increasingly consider the cost-effectiveness of novel treatments in reimbursement decisions, especially in oncology. As the number of therapies available to treat NSCLC increases, cost-effectiveness analyses will play a key role in reimbursement decisions in this area. Quantifying the relationship between health and quality of life for NSCLC patients via utility values is an important component of assessing the cost effectiveness of novel treatments.

The economic value of stream restoration

Collins, Alan; Rosenberger, Randy; Fletcher, Jerald

2005-02-01

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.

Diabetes is one of the diseases that required long treatment. Therapeutic outcome is one of the important factors that affect the quality of life. The purpose of this research is to know the effect of therapeutic result on quality of life in Abdul Azis Singkawang hospital. This study used Cross-sectional design. The inclusion criteria for this study was patients with type 2 diabetes mellitus (T2DM) outpatients over 18 years with ICD code X E.11. This study used the EQ-5D to measure patient's quality of life. We recruited 86 T2DM patients who met the inclusion criteria and were dominated by female respondents around 57%. The average value of quality of life EQ-5D was the index value 0.75±0.22 and visual analog scale 74.02±11.80. The result of the analysis showed that there was significant relationship between income and quality of life (p=0.001) and there was significant correlation between 2-hour PG and quality of life (p=0.037). The conclusion of this study was the therapeutic outcome affect the quality of life in 2-h PG, where the higher 2-h PG showed the low quality of life.

Which is more valuable, longer survival or better quality of life? Israeli oncologists' and family physicians' attitudes toward the relative value of new cancer and congestive heart failure interventions.

PubMed

2013-01-01

We determined how Israeli oncologists and family physicians value life-prolongation versus quality-of-life (QOL)-enhancing outcomes attributable to cancer and congestive heart failure interventions. We presented physicians with two scenarios involving a hypothetical patient with metastatic cancer expected to survive 12 months with current treatment. In a life-prolongation scenario, we suggested that a new treatment increases survival at an incremental cost of $50,000 over the standard of care. Participants were asked what minimum improvement in median survival the new therapy would need to provide for them to recommend it over the standard of care. In the QOL-enhancing scenario, we asked the maximum willingness to pay for an intervention that leads to the same survival as the standard treatment, but increases patient's QOL from 50 to 75 (on a 0-100 scale). We replicated these scenarios by substituting a patient with congestive heart failure instead of metastatic cancer. We derived the incremental cost-effectiveness ratio per quality-adjusted life-year (QALY) gained threshold implied by each response. In the life-prolongation scenario, the cost-effectiveness thresholds implied by oncologists were $150,000/QALY and $100,000/QALY for cancer and CHF, respectively. Cost-effectiveness thresholds implied by family physicians were $50,000/QALY regardless of the disease type. Willingness to pay for the QOL-enhancing scenarios was $60,000/QALY and did not differ by physicians' specialty or disease. Our findings suggest that family physicians value life-prolonging and QOL-enhancing interventions roughly equally, while oncologists value interventions that extend survival more highly than those that improve only QOL. These findings may have important implications for coverage and reimbursement decisions of new technologies.

2016-01-01

Evidence supports an inverse association of childhood socioeconomic status (SES) with systemic inflammation in adulthood. However, it remains to be determined whether this association is dependent on exposure to stressful life experiences. We predicted that the combination of a high number of recent negative life events and low childhood SES would be associated with the highest levels of both circulating interleukin (IL)-6 and lipopolysaccharide-stimulated production of IL-6. We tested this prediction among a community sample of 459 adults (47% male, mean [standard deviation] age = 42.8 [7.3] years). Inverse associations were found between childhood and adult SES indices with circulating IL-6 levels (r values between -0.07 and -0.16, p < .05) but not stimulated IL-6 levels (r values between -0.007 and 0.07, p > .05). The number of recent negative life events (mean [standard deviation] = 2.43 [2.34]) was not significantly related to subjective childhood SES and other SES indices (r values < 0.06, p > .10). Multivariate linear regression analyses revealed a significant association between the interaction of subjective childhood SES and recent negative life events and circulating IL-6 (β = -0.09, t(404) = -1.98, p = .049) and a marginally significant association with stimulated levels of IL-6 (β = -0.10, t(365) = -1.94, p = .054), whereas these covariate-adjusted models revealed no main effects for subjective SES or recent negative life events. The relationship between childhood SES and IL-6 seems to be moderated by recent life events, such that individuals with a relatively low childhood SES exhibit an inflammatory phenotype in the context of a high number of recent negative life events.

Religion and medical ethics.

Religious traditions of medical ethics tend to differ from more secular approaches by stressing limitations on autonomous decision-making, by more positively valuing the experience of suffering, and by drawing on beliefs and values that go beyond empiric verification. I trace the impact of these differences for some of the world's great religious traditions with respect to four issues: (1) religious conscientious objection to medical treatments; (2) end-of life decision-making, including euthanasia, physician-assisted suicide, and the withholding or withdrawing of life-sustaining treatments; (3) definitions of moral personhood (defining life's beginning and end); and (4) human sexuality. © 2013 Elsevier B.V.

Beyond the popular uses of the Internet by HCOs--for recruiting employees, purchasing supplies and promoting brand and service awareness--lie a host of opportunities to add value to consumers online. All HCO programs can be enhanced through online initiatives: wellness and health promotion, risk reduction, prevention, early detection, symptom management, life event management, acute treatment and rehabilitation, disease management and end-of-life improvement. And beyond online initiatives in each of these categories lies the potential to use the Net for reminding consumers, individually and collectively, of the health and quality of life benefits they are gaining, thereby adding to the HCO's marketing and PR success.

2014-07-01

This study compares differences in quality-adjusted life expectancy across the eight original National Occupational Research Agenda (NORA) industry sectors. Data from the 1997 to 2012 National Health Interview Survey (NHIS) were used to estimate quality-adjusted life years (QALYs) for all workers and by NORA sector. Differences in QALYs were calculated and translated into economic values using estimates of the societal willingness-to-pay per QALY. Mean QALYs across workers was 29.17 years. Among NORA sectors, wholesale, and retail trade workers had the highest average QALYs remaining (35.88), while mining workers had the lowest QALYs (31.4). The economic value of this difference ranges from $604,843 to $1,155,287 per worker depending on the societal willingness-to-pay per QALY. The value of life lost within some industries is very high relative to others. Additional investments in occupational safety, benefits, and health promotion initiatives may reduce these losses, but experimental research is needed to assess the effectiveness of such programs. © 2014 Wiley Periodicals, Inc.

Lindenfelser, Kathryn J; Hense, Cherry; McFerran, Katrina

2012-05-01

Research into the value of music therapy in pediatric palliative care (PPC) has identified quality of life as one area of improvement for families caring for a child in the terminal stages of a life-threatening illness. This small-scale investigation collected data in a multisite, international study including Minnesota, USA, and Melbourne, Australia. An exploratory mixed method design used the qualitative data collected through interviews with parents to interpret results from the PedsQL Family Impact Module of overall parental quality of life. Parents described music therapy as resulting in physical improvements of their child by providing comfort and stimulation. They also valued the positive experiences shared by the family in music therapy sessions that were strength oriented and family centered. This highlighted the physical and communication scales within the PedsQL Family Impact Module, where minimal improvements were achieved in contrast to some strong results suggesting diminished quality of life in cognitive and daily activity domains. Despite the significant challenges faced by parents during this difficult time, parents described many positive experiences in music therapy, and the overall score for half of the parents in the study did not diminish. The value of music therapy as a service that addresses the family-centered agenda of PPC is endorsed by this study.

Understanding individual dispersion from offshore natal areas to coastal nurseries during pelagic larval life is especially important for the sustainable management of exploited marine fish species. For several years, the hatching period, the larval life duration, the average growth rate and the otolith chemical composition (δ13C, δ18O, Sr:Ca and Ba:Ca) during the larval life were studied for young of the year (YOY) of sole collected in three main nurseries of the Gulf of Lions (GoL) (Thau, Mauguio and Berre). We investigated the spatial variation in the origin of the sole larvae which colonised the nurseries around the GoL, and whether temporal differences in environmental conditions during this life stage affected growth and larval life duration. The hatching period ranges from October to March, depending on year and site. Average ages at metamorphosis varied between 43 and 50 days, with the lowest and highest values consistently found for Mauguio and Berre, respectively. Otolith growth rates ranged between 2.7 and 3.2 μm d-1, with the lowest values in Thau and Mauguio and the highest in Berre. Otolith chemical composition during the larval life also varied, suggesting contrasted larval environmental histories in YOY among nurseries. In fishes from Berre and Mauguio, larval life was more influenced by the Rhône River, showing consistently higher larval Ba:Ca ratios (10/23 μmol mol-1) and lower δ13C (-6.5/-6.1‰) and δ18O values (-1.6/0.1‰) than for Thau (with Ba:Ca ratios < 8 μmol mol-1, δ13C ˜-2.3‰ and δ18O ˜1.5‰). Differences in larval otolith composition were observed for 2004, with higher Ba:Ca and lower δ13C and δ18O values than in the two other years. These differences were explained by changes in composition and chemical signatures of water masses after an exceptional flooding event of the Rhône River in late 2003.

High-precision half-life and branching-ratio measurements for the superallowed β+ emitter 26Alm were performed at the TRIUMF-ISAC radioactive ion beam facility. An upper limit of ≤ 15 ppm at 90% C.L. was determined for the sum of all possible non-analogue β+/EC decay branches of 26Alm, yielding a superallowed branching ratio of 100.0000+0-0.0015%. A value of T1/2 = 6:34654(76) s was determined for the 26Alm half-life which is consistent with, but 2.5 times more precise than, the previous world average. Combining these results with world-average measurements yields an ft value of 3037.58(60) s, the most precisely determined for any superallowed emitting nucleus to date. This high-precision ft value for 26Alm provides a new benchmark to refine theoretical models of isospin-symmetry-breaking effects in superallowed β decays.

A normative price for energy from an electricity generation system: An Owner-dependent Methodology for Energy Generation (system) Assessment (OMEGA). Volume 1: Summary

1981-01-01

The utility owned solar electric system methodology is generalized and updated. The net present value of the system is determined by consideration of all financial benefits and costs (including a specified return on investment). Life cycle costs, life cycle revenues, and residual system values are obtained. Break even values of system parameters are estimated by setting the net present value to zero. While the model was designed for photovoltaic generators with a possible thermal energy byproduct, it applicability is not limited to such systems. The resulting owner-dependent methodology for energy generation system assessment consists of a few equations that can be evaluated without the aid of a high-speed computer.

This study aimed at determining the effect of chitosan coating on shelf life extension of salmon ( Salmo salar ) fillets. The success of edible coatings depends highly on their effective wetting capacity of the surfaces on which they are applied. In this context in a first stage the surface properties of salmon fillets and the wetting capacity of the coatings on fish were evaluated. In terms of wettability there were no significant differences (p > 0.05) between the solutions presenting higher values (solutions 1-4); therefore, solution 1 with a spreading coefficient (Ws) of -4.73 mN m(-1), was chosen to be subsequently analyzed and applied on fish fillets. For shelf life analyses the fillets were coated and stored at 0 °C for 18 days. The control and coated fish samples were analyzed periodically for total aerobic plate count (TPC), pH, total volatile base nitrogen (TVB-N), trimethylamine (TMA), thiobarbituric acid (TBA), and ATP breakdown products (K value). The results showed that fish samples coated with chitosan presented a significant reduction (p < 0.05) for pH and K value after 6 days and for TVB, TMA, and TBA values after 9 days of storage, when compared to control samples. In terms of microbial growth, a slower increase in TPC was observed for the coated fish, indicating that chitosan-based coatings were effective in extending for an additional 3 days the shelf life of the salmon. These results demonstrate that chitosan-based coatings may be an alternative for extending the shelf life of salmon fillets during storage at 0 °C.

The present study examined the predictive value of emotional competence and the five-factor model of personality on the quality of life of children with asthma. Participants were 90 children (M age = 11.73, SD = 2.60) having controlled and partly controlled asthma, undergoing everyday treatment. Children filled in questionnaires assessing emotional competence and quality of life. Parents completed questionnaires assessing the personality of their child. Results showed that two emotional competences, bodily awareness and verbal sharing of emotions, were related to the quality of life of children with asthma. Moreover, one personality trait, benevolence, was associated with children's quality of life. Regression analyses showed that the predictive value of these three dimensions remained significant over and above asthma control and socio-demographic variables frequently associated with the quality of life of children with asthma (age, gender, and educational level of parents). These findings emphasize the importance of alerting the clinician who works with children with asthma to observe and assess the child's expression of emotions, attention to bodily sensations, and benevolence.

Objective To explore how statements drawn from patients’ written life stories can help general practitioners understand their patients’ maladaptive thought patterns and their negative schemata. Design Qualitative study of written life stories. Setting General practice in Copenhagen, Denmark. Subjects A total of 22 consecutive patients aged 23–49 years, who were invited by their GP to participate in cognitive therapy owing to depressive or anxiety-related disorders, including unexplained bodily symptoms. Theoretical frame of reference Beck's information-processing model of anxiety. Results Analysis of the written life stories disclosed aspects of negative expectations of life, the self, or the values and capabilities of others or of the patient him- or herself. Three main beliefs were identified: (1) the world is evil, (2) only the perfect is of value, and (3) emotions are dangerous. The patients describe events and experiences in negative terms that others might have interpreted as neutral or positive. For some this translated into a sort of all-or-nothing kind of thinking. Anger and other strong feelings were forbidden. Responsibility for the life of others was a dominant feature. Conclusions Written life stories reveal knowledge of the patient's dysfunctional thought patterns. This may be a useful shortcut in therapy. PMID:17354157

Working life tables, Bangladesh 1981.

Data from the 1981 Bangladesh Population Census were used to construct life tables for working men and women. Bangladesh has a dependency burden of 109 dependents to 100 economically active population. Labor force participation rates in 1981 were 74.1/100 population aged 10 years and over for males and 4.3/100 population aged 10 years and over for females. The age-specific economic activity rates provided the essential link in translating life table data to working life table data. It was calculated that a newborn Bangladesh male had a working life expectancy of 37.8 years and an overall life expectancy of 50.0 years; working life expectancy peaks at 44.2 years at 10 years of age. A newborn female has a working life expectancy of 1.8 years and an overall life expectancy of 49.0 years; a maximum working life expectancy of 2.4 years is obtained at 10 years of age. In the period 1962-81, male working life expectancy registered a slight decline at all ages, while female working life expectancy increased by about 6 months for ages up to 30 years. Mortality accounts for a loss of about 10% of gross years of active life in the 10-69-year goups and 20% in the 10-79-year age group. The male working life expectancy values for Bangladesh in 1981 correspond well with those found in India in 1971, Pakistan in 1978, and Sri Lanka in 1971. However, there is wide divergency in terms of female working life expectancy values: such rates were significantly higher in Sri Lanka and India than in Bangladesh up to the age of 30 years, after which point there was little divergence.

Predictive Performance Assessment: Trait and State Dimensions Should not be Confused

One of the major aims of performance investigation is to obtain a measure predicting real-life performance, in order to prevent consequences of a potential decrement. Whereas the predictive validity of such assessment has been extensively described for long-term outcomes, as is the case for testing in selection context, equivalent evidence is lacking regarding the short-term predictive value of cognitive testing, i.e., whether these results reflect real-life performance on an immediately subsequent task. In this series of experiments, we investigated both medium-term and short-term predictive value of psychophysiological testing with regard to real-life performance in two operational settings: military student pilots with regard to their success on an evaluation flight, and special forces candidates with regard to their performance on their training course. Our results showed some relationships between test performance and medium-term outcomes. However, no short-term predictive value could be identified for cognitive testing, despite the fact physiological data showed interesting trends. We recommend a critical distinction between "state" and "trait" dimensions of performance with regard to the predictive value of testing.

Background Patient decisions are influenced by their personal values. However, there is a lack of clarity and attention on the concept of patient values in the clinical context despite clear emphasis on patient values in evidence-based medicine and shared decision making. The aim of the study was to explore the concept of patient values in the context of making decisions about insulin initiation among people with type 2 diabetes. Methods and Findings We conducted individual in-depth interviews with people with type 2 diabetes who were making decisions about insulin treatment. Participants were selected purposively to achieve maximum variation. A semi-structured topic guide was used to guide the interviews which were audio-recorded and analysed using a thematic approach. We interviewed 21 participants between January 2011 and March 2012. The age range of participants was 28–67 years old. Our sample comprised 9 women and 12 men. Three main themes, ‘treatment-specific values’, ‘life goals and philosophies’, and ‘personal and social background’, emerged from the analysis. The patients reported a variety of insulin-specific values, which were negative and/or positive beliefs about insulin. They framed insulin according to their priorities and philosophies in life. Patients’ decisions were influenced by sociocultural (e.g. religious background) and personal backgrounds (e.g. family situations). Conclusions This study highlighted the need for expanding the current concept of patient values in medical decision making. Clinicians should address more than just values related to treatment options. Patient values should include patients’ priorities, life philosophy and their background. Current decision support tools, such as patient decision aids, should consider these new dimensions when clarifying patient values. PMID:24282518

Accurate shelf-life dating of food products is crucial for consumers and industries. Therefore, in this study we applied a science-based approach for shelf-life assessment, including accelerated shelf-life testing (ASLT), acceptability testing and the screening of analytical attributes for fast shelf-life predictions. Shelf-stable strawberry juice was selected as a case study. Ambient storage (20 °C) had no effect on the aroma-based acceptance of strawberry juice. The colour-based acceptability decreased during storage under ambient and accelerated (28-42 °C) conditions. The application of survival analysis showed that the colour-based shelf-life was reached in the early stages of storage (≤11 weeks) and that the shelf-life was shortened at higher temperatures. None of the selected attributes (a * and ΔE * value, anthocyanin and ascorbic acid content) is an ideal analytical marker for shelf-life predictions in the investigated temperature range (20-42 °C). Nevertheless, an overall analytical cut-off value over the whole temperature range can be selected. Colour changes of strawberry juice during storage are shelf-life limiting. Combining ASLT with acceptability testing allowed to gain faster insight into the change in colour-based acceptability and to perform shelf-life predictions relying on scientific data. An analytical marker is a convenient tool for shelf-life predictions in the context of ASLT. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

The effect of high hydrostatic pressure on antioxidant activity, total phenolic compounds, physicochemical characteristics, color, pectin methylesterase activity, and microbiological count were evaluated during the shelf life of Pêra-Rio orange juice. Pressurized (520 MPa, 60 ℃, for 360 s), non-processed and pasteurized (95 ℃/30 s) orange juice were compared at zero time of storage. Pressurized and pasteurized juices were studied during a refrigerated 90-day shelf life. Pressurization did not cause expressive change in physicochemical characteristics of Pêra-Rio orange juice along shelf life, but significantly reduced pectin methylesterase residual activity to 13% and microbiological counts below detection levels up to 68 days of storage, with small counts (30.0 × 10 CFU/mL mesophilic aerobic bacteria and 20.7 × 10 CFU/mL yeast and mold) at 90 days, capable of ensuring the juice's stability along shelf life. Lightness ( L*) and b* values were significantly reduced by high hydrostatic pressure during shelf life, while a* values were significantly higher. Ascorbic acid decreased around 80% during shelf life. Antioxidant activity remained stable after processing and during storage.

Qualitative Characteristics and Determining Shelf-Life of Milk Beverage Product Supplemented with Coffee Extracts

This study was conducted to establish the shelf-life of a milk beverage product supplemented with coffee extracts. Qualitative changes including peroxide value (PV), microorganism content, caffeine content, and sensory evaluation were measured periodically in beverages kept at 10, 20, and 30°C for 8 wk. Lipid oxidation of the product was measured by peroxide value analysis, and apparent changes were observed during a 4 wk storage period. Caffeine analysis revealed that the changes in caffeine content were negligible during the storage period. Total aerobic bacteria, Escherichia coli, yeast, and mold were not detected in the products during an 8 wk storage period. Sensory evaluation revealed that after 4 wk of storage overall acceptance was less than 3 points on a 5-point scale. In this study, PV was used as an indicator of the shelf-life of the milk beverage product. PV analysis revealed that a value of 20 meq/kg was the end of the shelf-life using the Arrhenius equation and the accelerated shelf-life test (ASLT). Assuming that the beverages are kept at 4°C during distribution, calculation of when the PV reached the quality limit point (20 meq/kg) was done with the equation ln(PV) = 0.3644X − 2.21834 and, using that equation, PV = e0.3644X-2.21834 was calculated. Therefore, 14.3086 wk was determined to be the shelf-life of the milk beverage supplemented with coffee when stored at 4°C. PMID:28515654

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

Wrongful life and birth.

PubMed

Evgenia, Smyrnaki

2012-03-01

The main scope of the article is the bioethical and legal issues of wrongful birth and wrongful life with reference to doctors' medical liability. Nowadays, prenatal tests tend to substitute the eugenic practice of Spartan inspection to raise a strong and healthy child. Should the doctor misinform the parents that the child is healthy and the parents do not exercise the right to abort the pregnancy, the doctor can be held liable and claims on wrongful life or birth are raised against him. "Wrongful life" is an oxymoron itself since "life" which has an intrinsic value and sanctity is attributed a negative aspect and is regarded as damage. Courts around the world have awarded parents compensation on that legal ground. In the Perruche affair (2000), where the mother was wrongly diagnosed and gave birth to Nicholas, who had serious neurological problems, the court conferred the right on the child itself, causing an uproar in France. The decision was criticized for encouraging eugenics and diminishing the value of handicapped people. The different approaches to the above issues by different courts around the world (US, EU) with reference to (bio) ethical concerns are going to be examined. We will try to give an answer on whether it is possible for courts to support on legal and bioethical grounds that a child with disabilities should not have been born as a result of the doctor's negligent conduct. In such cases, the limits of normality and the value of life are challenged

2018-06-01

The present paper tackles an important but unmapped problem of the reliability estimations of smart materials. First, an experimental setup is developed for accelerated life testing of the shape memory alloy (SMA) springs. Generalized log-linear Weibull (GLL-Weibull) distribution-based novel approach is then developed for SMA spring life estimation. Applied stimulus (voltage), elongation and cycles of operation are used as inputs for the life prediction model. The values of the parameter coefficients of the model provide better interpretability compared to artificial intelligence based life prediction approaches. In addition, the model also considers the effect of operating conditions, making it generic for a range of the operating conditions. Moreover, a Bayesian framework is used to continuously update the prediction with the actual degradation value of the springs, thereby reducing the uncertainty in the data and improving the prediction accuracy. In addition, the deterioration of material with number of cycles is also investigated using thermogravimetric analysis and scanning electron microscopy.

The Bioethical Concept of Life for Life in Judaism, Catholicism, and Islam: Abortion When the Mother’s Life is in Danger

2010-01-01

Modern secular bioethics has focused on developing a set of universal principles to guide clinical decision making. However, this ignores the important role of religion in resolving bioethical questions. It is imperative that health-care providers understand these belief systems in order to traverse value conflicts and provide the highest quality care to a diverse population. This paper focuses on the process of bioethical deliberation in Judaism, Catholicism, and Islam. Abortion is normatively prohibited in each faith and through examining how each ethical code allows for abortion when the mother’s life is in peril due to the fetus, we highlight the value of unborn life in each faith. Orthodox Judaism uses the concept of rodef, or pursuer, to permit abortion in this scenario, Catholicism uses the moral concept of “double effect,” while Islamic law cites the maqāṣid, higher objectives of the law, to permit abortion in this scenario.

We have made a new determination of the half-life of the radioactive isotope 60Fe using high precision measurements of the number of 60Fe atoms and their activity in a sample containing over 10(15) 60Fe atoms. Our new value for the half-life of 60Fe is (2.62+/-0.04) x 10(6) yr, significantly above the previously reported value of (1.49+/-0.27) x 10(6) yr. Our new measurement for the lifetime of 60Fe has significant implications for interpretations of galactic nucleosynthesis, for determinations of formation time scales of solids in the early Solar System, and for the interpretation of live 60Fe measurements from supernova-ejecta deposits on Earth.

Work ability of nurses is an index of their job satisfaction and is a crucial factor in job quality and security. This study aimed to investigate the association between work ability and quality of working life and to determine the effective demographic and background variables, among nurses. The present study was conducted among nurses, working in educational hospitals under the supervision of Tehran University of Medical Sciences in 2014. Work Ability Index (WAI) and Work-related Quality of Life (WRQoL) were used. The mean WAI was significantly associated with total WRQoL score and the two of its sub-items including Stress at Work, and General Well-Being ( P -value=0.001). Moreover, the results showed a significant correlation between total WRQoL and WAI Subscales including mental resources ( P -value=0.001), number of current diseases ( P- value=0.02), and work ability in relation to the job demands ( P -value=0.04). The WRQoL and WAI showed significant associations with age and job experience ( P -value=0.001). The average score of WAI and WRQoL was statistically different among various working units ( P -value=0.001). Overall, results support the association between nurses work ability and WRQoL. Monitoring the WRQoL and work ability of employees would help organizations to know their status and take measures to ameliorate the working conditions.

The half-life of Th232 has been calculated by determining an absolute gamma-disintegration rate for Tl208 in equilibrium with Th232 for three old thorium nitrate salts and one natural thorite sample. The branching ratio, ??(??+??), for Bi212, a necessary parameter in the calculation, was also measured. The half-life of Th232 was found to be 1.42??1010 years within an estimated error of 5%, which is essentially in agreement with the presently accepted value. The branching ratio, ??(??+??), of Bi212 was found to be 0.362??0.006, about 7.4% higher than the currently accepted value. ?? 1956 The American Physical Society.

The pro-life argument from substantial identity and the pro-choice argument from asymmetric value: a reply to Patrick Lee.

PubMed

Reiman, Jeffrey

2007-07-01

Lee claims that foetuses and adult humans are phases of the same identical substance, and thus have the same moral status because: first, foetuses and adults are the same physical organism, and second, the development from foetus to adult is quantitative and thus not a change of substance. Versus the first argument, I contend that the fact that foetuses and adults are the same physical organism implies only that they are the same thing but not the same substance, much as living adults and their corpses are the same thing (same body) but not the same substance. Against Lee's second argument, I contend that Lee confuses the nature of a process with the nature of its result. A process of quantitative change can produce a change in substance. Lee also fails to show that foetuses are rational and thus have all the essential properties of adults, as required for them to be the same substance. Against the pro-choice argument from asymmetric value (that only the fact that a human has become conscious of its life and begun to count on its continuing can explain human life's asymmetric moral value, i.e. that it is vastly worse to kill a human than not to produce one), Lee claims that foetus's lives are asymmetrically valuable to them before consciousness. This leads to counterintuitive outcomes, and it confuses the goodness of life (a symmetric value that cannot account for why it is worse to kill a human than not produce one) with asymmetric value.

Rebranding exercise: closing the gap between values and behavior.

Segar, Michelle L; Eccles, Jacquelynne S; Richardson, Caroline R

Behavior can only be understood by identifying the goals to which it is attached. Superordinate-level goals are linked to individuals' values, and may offer insights into how to connect exercise with their core values and increase participation in sustainable ways. A random sample of healthy midlife women (aged 40-60y) was selected to participate in a year-long mixed-method study (n = 226). Superordinate goals were measured inductively and analyzed using grounded theory analysis. Attainment Value and Exercise Participation were quantitatively measured. An ANOVA and pairwise comparisons were conducted to investigate the differences between superordinate exercise goals in attainment value. This study fit a Linear Mixed Model to the data to investigate the fixed effects of superordinate goals on exercise participation, controlling for BMI and social support. Participants mainly exercised to achieve Healthy-Aging, Quality-of-Life, Current-Health, and Appearance/Weight superordinate goals. Despite equally valuing Healthy-Aging, Quality-of-Life, and Current-Health goals, participants with Quality-of-Life goals reported participating in more exercise than those with Current-Health (p < 0.01), and Healthy-Aging (p = 0.06) goals. Superordinate exercise goals related to health and healthy aging are associated with less exercise than those related to enhancing daily quality of life, despite being equally valued. While important, pursuing distant benefits from exercise such as health promotion, disease prevention, and longevity might not be as compelling to busy individuals compared to their other daily priorities and responsibilities. By shifting our paradigm from medicine to marketing, we can glean insights into how we can better market and "sell" exercise. Because immediate payoffs motivate behavior better than distant goals, a more effective "hook" for promoting sustainable participation might be to rebrand exercise as a primary way individuals can enhance the quality of their daily lives. These findings have important implications for how we as a culture, especially those in fitness-related businesses, health promotion, health care, and public health, prescribe and market exercise on individual and population levels.

The main objective of this study is to estimate the monetary value of the gains of healthy days and life expectancy due to the ambient air quality standard that came into effect in 2014 by estimating the country-specific value of a life year (VOLY) and the value of the healthier and longer life (VHLL) for Turkey. Contingent valuation method is adopted to reveal individuals’ willingness to pay for an improvement of health condition and the extension of their life expectancy by avoiding respiratory and lung related illnesses. VHLL is composed of two parts, WTP for an extension of one’s life years (VOLY) and for an increase in the number of healthy days throughout one’s life time (VHLL-VOLY). We found that close to 80% of WTP is allocated to the latter component of VHLL and only 20% is for VOLY mainly due to Islamic beliefs of the respondents. A total of 1314 observations are collected by face-to-face interviews from Afsin-Elbistan, Kutahya-Tavsanli and Ankara. The estimated VHLL and VOLY are [41,750 TL, 10,258 TL] with all the observations, [30,185 TL, 7132 TL] for Afsin-Elbistan, [31,718 TL, 7081 TL] for Kutahya-Tavsanli and [52,334 TL, 14,813 TL] for Ankara. The Inverse-U shaped relationship between Age and WTP is confirmed. The income elasticities of WTP is found to be close to 0.5 for all study areas while an Inverse-U shaped relationship between the household income and Income Elasticity of WTP is observed in the income group based analysis. Age and household income are the two prominent determinants of VHLL. PMID:28961227

Contingent valuation method is adopted to reveal individuals' willingness to pay for an improvement of health condition and the extension of their life expectancy by avoiding respiratory and lung related illnesses. VHLL is composed of two parts, WTP for an extension of one's life years (VOLY) and for an increase in the number of healthy days throughout one's life time (VHLL-VOLY). We found that close to 80% of WTP is allocated to the latter component of VHLL and only 20% is for VOLY mainly due to Islamic beliefs of the respondents. A total of 1314 observations are collected by face-to-face interviews from Afsin-Elbistan, Kutahya-Tavsanli and Ankara. The estimated VHLL and VOLY are [41,750 TL, 10,258 TL] with all the observations, [30,185 TL, 7132 TL] for Afsin-Elbistan, [31,718 TL, 7081 TL] for Kutahya-Tavsanli and [52,334 TL, 14,813 TL] for Ankara. The Inverse-U shaped relationship between Age and WTP is confirmed. The income elasticities of WTP is found to be close to 0.5 for all study areas while an Inverse-U shaped relationship between the household income and Income Elasticity of WTP is observed in the income group based analysis. Age and household income are the two prominent determinants of VHLL.

To explore the interaction between vision impairment, perceived quality of life loss and willingness to trade remaining life for vision gain. Community-based cross-sectional study. Legally blind or severely vision-impaired people selected randomly from the Association for the Blind of Western Australia register. Individuals were examined by consultant ophthalmologists and completed the Impact of Vision Impairment profile quality of life assessment and a Time Trade-Off evaluation. Vision-related utility values were calculated. The results were analysed using univariate and multivariate regression methods. IVI Rasch Logits and TTO utility values (TTO UV). 156 people volunteered to contribute to the study. The median age was 80 (19-97) years, and 56% were female. Being legally blind (logMAR > 1) (95% CI 1.1 to 5.2, P = 0.003), clinically depressed (95% CI -11.2 to -1.8, P = 0.007) or more than 40 years of age (95% CI 0.9 to 8.1, P = 0.015) significantly lowered overall impact of vision impairment scores. The emotional domain of impact of vision impairment was associated with willingness to trade part of remaining life. A 5-Logit increase in impact of vision impairment emotional score resulted in a 21% (95% CI 10 to 31) decrease in the odds of being likely to trade life for sight. The Australian definition of blindness compared with World Health Organisation or USA best separates those with perceived loss and appears useful in identifying vision loss-related morbidity. These results suggest that emotional health and lack of depression are important determinants for quality and value of life. © 2011 The Authors.

Define and establish the reference values of the CAVIPRES-30 Questionnaire, a health related quality of life questionnaire specific for prostate cancer patients. The CAVIPRES-30 was administered to 2,630 males with prostate cancer included by 238 Urologist belonging to the Spanish National Healthcare System. Descriptive analysis on socio-demographic and clinical data were performed, and multivariate analyses were used to corroborate that stratification variables were statistically significantly and independently associated to the overall score of the questionnaire. The variables Time since diagnosis of the illness, whether the patient had a Stable partner or not, if he was, or not, undergoing Symptomatic treatment were statistically significantly and independently associated (P < .001) to the overall score of the questionnaire. The reference values table of the CAVIPRES-30 questionnaire is made up of different kinds of information of each patient profile: sample size, descriptive statistics with regard to the overall score, Cronbach's alpha value (between .791 and .875) and the questionnaire's values are reported by deciles. The results of this study contribute new proof as to the suitability and usefulness of the CAVIPRES-30 questionnaire as an instrument for assessing individually the quality of life of prostate cancer.

By maintaining sufficient cerebral blood flow and oxygenation, the goal of cardiopulmonary resuscitation (CPR) is to preserve the pre-arrest neurological state. To date, cerebral monitoring abilities during CPR have been limited. Therefore, we investigated the time-course of cerebral oxygen saturation values (rSO₂) during advanced life support in out-of-hospital cardiac arrest. Our primary aim was to compare rSO₂ values during advanced life support from patients with return of spontaneous circulation (ROSC) to patients who did not achieve ROSC. We performed an observational study to measure rSO₂ using Equanox (Nonin, Plymouth, MI) from the start of advanced life support in the pre-hospital setting. rSO₂ of 49 consecutive out-of-hospital cardiac arrest patients were analyzed. The total increase from initial rSO₂ value until two minutes before ROSC or end of advanced life support efforts was significantly larger in the group with ROSC 16% (9 to 36) compared to the patients without ROSC 10% (4 to 15) (P = 0.02). Mean rSO₂ from the start of measurement until two minutes before ROSC or until termination of advanced life support was higher in patients with ROSC than in those without, namely 39% ± 7 and 31% ± 4 (P = 0.05) respectively. During pre-hospital advanced life support, higher increases in rSO₂ are observed in patients attaining ROSC, even before ROSC was clinically determined. Our findings suggest that rSO₂ could be used in the future to guide patient tailored treatment during cardiac arrest and could therefore be a surrogate marker of the systemic oxygenation state of the patient.

To assess the conferred value and average cost-utility (cost-effectiveness) for intravitreal ranibizumab used to treat occult/minimally classic subfoveal choroidal neovascularization associated with age-related macular degeneration (AMD). Value-based medicine cost-utility analysis. MARINA (Minimally Classic/Occult Trial of the Anti-Vascular Endothelial Growth Factor Antibody Ranibizumab in the Treatment of Neovascular AMD) Study patients utilizing published primary data. Reference case, third-party insurer perspective, cost-utility analysis using 2006 United States dollars. Conferred value in the forms of (1) quality-adjusted life-years (QALYs) and (2) percent improvement in health-related quality of life. Cost-utility is expressed in terms of dollars expended per QALY gained. All outcomes are discounted at a 3% annual rate, as recommended by the Panel on Cost-effectiveness in Health and Medicine. Data are presented for the second-eye model, first-eye model, and combined model. Twenty-two intravitreal injections of 0.5 mg of ranibizumab administered over a 2-year period confer 1.039 QALYs, or a 15.8% improvement in quality of life for the 12-year period of the second-eye model reference case of occult/minimally classic age-related subfoveal choroidal neovascularization. The reference case treatment cost is $52652, and the cost-utility for the second-eye model is $50691/QALY. The quality-of-life gain from the first-eye model is 6.4% and the cost-utility is $123887, whereas the most clinically simulating combined model yields a quality-of-life gain of 10.4% and cost-utility of $74169. By conventional standards and the most commonly used second-eye and combined models, intravitreal ranibizumab administered for occult/minimally classic subfoveal choroidal neovascularization is a cost-effective therapy. Ranibizumab treatment confers considerably greater value than other neovascular macular degeneration pharmaceutical therapies that have been studied in randomized clinical trials.

Strategic targeting of advance care planning interventions: the Goldilocks phenomenon.

PubMed

Billings, J Andrew; Bernacki, Rachelle

2014-04-01

Strategically selecting patients for discussions and documentation about limiting life-sustaining treatments-choosing the right time along the end-of-life trajectory for such an intervention and identifying patients at high risk of facing end-of-life decisions-can have a profound impact on the value of advance care planning (ACP) efforts. Timing is important because the completion of an advance directive (AD) too far from or too close to the time of death can lead to end-of-life decisions that do not optimally reflect the patient's values, goals, and preferences: a poorly chosen target patient population that is unlikely to need an AD in the near future may lead to patients making unrealistic, hypothetical choices, while assessing preferences in the emergency department or hospital in the face of a calamity is notoriously inadequate. Because much of the currently studied ACP efforts have led to a disappointingly small proportion of patients eventually benefitting from an AD, careful targeting of the intervention should also improve the efficacy of such projects. A key to optimal timing and strategic selection of target patients for an ACP program is prognostication, and we briefly highlight prognostication tools and studies that may point us toward high-value AD interventions.

Estimation of shelf life of natural rubber latex exam-gloves based on creep behavior.

Das, Srilekha Sarkar; Schroeder, Leroy W

2008-05-01

Samples of full-length glove-fingers cut from chlorinated and nonchlorinated latex medical examination gloves were aged for various times at several fixed temperatures and 25% relative humidity. Creep testing was performed using an applied stress of 50 kPa on rectangular specimens (10 mm x 8 mm) of aged and unaged glove fingers as an assessment of glove loosening during usage. Variations in creep curves obtained were compared to determine the threshold aging time when the amount of creep became larger than the initial value. These times were then used in various models to estimate shelf lives at lower temperatures. Several different methods of extrapolation were used for shelf-life estimation and comparison. Neither Q-factor nor Arrhenius activation energies, as calculated from 10 degrees C interval shift factors, were constant over the temperature range; in fact, both decreased at lower temperatures. Values of Q-factor and activation energies predicted up to 5 years of shelf life. Predictions are more sensitive to values of activation energy as the storage temperature departs from the experimental aging data. Averaging techniques for prediction of average activation energy predicted the longest shelf life as the curvature is reduced. Copyright 2007 Wiley Periodicals, Inc.

Advanced Life Support System Value Metric

NASA Technical Reports Server (NTRS)

Jones, Harry W.; Arnold, James O. (Technical Monitor)

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.

Plant carbon (C) content is one of the most important plant traits and is critical to the assessment of global C cycle and ecological stoichiometry; however, the global variations in plant C content remain poorly understood. In this study, we conducted a global analysis of the plant C content by synthesizing data from 4318 species to document specific values and their variation of the C content across plant organs and life forms. Plant organ C contents ranged from 45.0 % in reproductive organs to 47.9 % in stems at global scales, which were significantly lower than the widely employed canonical value of 50 %. Plant C content in leaves (global mean of 46.9 %) was higher than that in roots (45.6 %). Across life forms, woody plants exhibited higher C content than herbaceous plants. Conifers, relative to broad-leaved woody species, had higher C content in roots, leaves, and stems. Plant C content tended to show a decrease with increasing latitude. The life form explained more variation of the C content than climate. Our findings suggest that specific C content values of different organs and life forms developed in our study should be incorporated into the estimations of regional and global vegetation biomass C stocks.

This paper describes a comparative analysis of public transport alternatives in the city of Kaunas, Lithuania. An LCA (Life Cycle Assessment) inventory analysis of fuel chains was undertaken using the midi urban bus and a similar type of trolleybus. The inventory analysis of fuel chains followed the guidelines provided by the ISO 14040 and ISO 14044 standards. The ReCiPe Life Cycle Impact Assessment (LCIA) methodology was used to quantify weighted damage originating from five alternative fuel chains. The compressed biogas fuel chain had the lowest weighted damage value, namely 45.7 mPt/km, whereas weighted damage values of the fuel chains based on electricity generation for trolleybuses were 60.6 mPt/km (for natural gas) and 78.9 mPt/km (for heavy fuel oil). The diesel and compressed natural gas fuel chains exhibited considerably higher damage values of 114.2 mPt/km and 132.6 mPt/km, respectively. The comparative life cycle assessment of fuel chains suggested that biogas-powered buses and electric trolleybuses can be considered as the best alternatives to use when modernizing the public transport fleet in Kaunas.

Hanford, Anthony J.

2004-01-01

This document provides values at the assembly level for the subsystems described in the Fiscal Year 2004 Advanced Life Support Research and Technology Development Metric (Hanford, 2004). Hanford (2004) summarizes the subordinate computational values for the Advanced Life Support Research and Technology Development (ALS R&TD) Metric at the subsystem level, while this manuscript provides a summary at the assembly level. Hanford (2004) lists mass, volume, power, cooling, and crewtime for each mission examined by the ALS R&TD Metric according to the nominal organization for the Advanced Life Support (ALS) elements. The values in the tables below, Table 2.1 through Table 2.8, list the assemblies, using the organization and names within the Advanced Life Support Sizing Analysis Tool (ALSSAT) for each ALS element. These tables specifically detail mass, volume, power, cooling, and crewtime. Additionally, mass and volume are designated in terms of values associated with initial hardware and resupplied hardware just as they are within ALSSAT. The overall subsystem values are listed on the line following each subsystem entry. These values are consistent with those reported in Hanford (2004) for each listed mission. Any deviations between these values and those in Hanford (2004) arise from differences in when individual numerical values are rounded within each report, and therefore the resulting minor differences should not concern even a careful reader. Hanford (2004) u es the uni ts kW(sub e) and kW(sub th) for power and cooling, respectively, while the nomenclature below uses W(sub e) and W(sub th), which is consistent with the native units within ALSSAT. The assemblies, as specified within ALSSAT, are listed in bold below their respective subsystems. When recognizable assembly components are not listed within ALSSAT, a summary of the assembly is provided on the same line as the entry for the assembly. Assemblies with one or more recognizable components are further described by the indented entries below them. See Yeh, et al. (2002), Yeh, et al. (2003), and Yeh, et al. (2004) for details about ALSSAT organization. Except for the dry food mass listed within the Food Processing, Packaging, and Storage within the Food Subsystem, total values for assemblies would be the sum of their components. The Dry Food Mass, however, is that portion of the food system that was neglected during the computation of the Fiscal Year 2004 ALS R&TD Metric. It is listed here to provide a reference, but it is otherwise ignored in the overall totals. See Hanford (2004) for details of this process and supporting rationale. When applicable, the technology label from ALSSAT is listed in the second column, and the associated abbreviations are listed below in Section 4. For more details of the technologies assumed for each mission, please see Hanford (2004) for descriptions of each subsystem and an overall life support system schematic.

Eco-efficiency in extended supply chains: a case study of furniture production.

PubMed

Michelsen, Ottar; Fet, Annik Magerholm; Dahlsrud, Alexander

2006-05-01

This paper presents a methodology about how eco-efficiency in extended supply chains (ESCs) can be understood and measured. The extended supply chain includes all processes in the life cycle of a product and the eco-efficiency is measured as the relative environmental and value performance in one ESC compared to other ESCs. The paper is based on a case study of furniture production in Norway. Nine different environmental performance indicators are identified. These are based on suggestions from the World Business Council for Sustainable Development and additional indicators that are shown to have significant impacts in the life cycle of the products. Value performance is measured as inverse life cycle costs. The eco-efficiency for six different chair models is calculated and the relative values are shown graphically in XY-diagrams. This provides information about the relative performance of the products, which is valuable in green procurement processes. The same method is also used for analysing changes in eco-efficiency when possible alterations in the ESC are introduced. Here, it is shown that a small and realistic change of end-of-life treatment significantly changes the eco-efficiency of a product.

We propose from the Marxist perspective of the construction of knowledge, a theoretical and methodological framework for understanding social values by capturing everyday representations. We assume that scientific research brings together different dimensions: epistemological, theoretical and methodological that consistently to the other instances, proposes a set of operating procedures and techniques for capturing and analyzing the reality under study in order to expose the investigated object. The study of values reveals the essentiality of the formation of judgments and choices, there are values that reflect the dominant ideology, spanning all social classes, but there are values that reflect class interests, these are not universal, they are formed in relationships and social activities. Basing on the Marxist theory of consciousness, representations are discursive formulations of everyday life - opinion or conviction - issued by subjects about their reality, being a coherent way of understanding and exposure social values: focus groups show is suitable for grasping opinions while interviews show potential to expose convictions.

1998-01-01

The case manager's role in our complex health care system is demanding and draining without some self-reflective attention. The Wheel of Life is a key tool for individuals to assess how well they are leading a fully balanced life. The eight aspects of a balanced life--values, self-care, work, relationships, leisure, relaxation, exercise, and centering--are explained and discussed. A self-reflective activity is presented that encourages readers to assess their current life balance. This focused clarification of personal and professional life will facilitate a more fully balanced life with rewards for case managers as individuals, and for their family, clients, and the health care organization.

When it comes to measuring value, few HMOs can make the grade.

Like all organizations, managed care organizations (MCOs) must deliver value to customers, and to be sure of keeping them, ensure those customers know they have gained value. MCOs can choose any mix of insurance, protection, or experience value from particular encounters with customers, or durable value from their relationship with customers. Many have done a good job of tracking and enabling employers to appreciate the impact they have had on business performance, but few have done the same for the health and quality-of-life they deliver to consumers. MCOs already participate in the delivery of significant and enduring life value to consumers. It makes sense to track and remind consumers of the positive differences MCOs make, and thereby obtain member satisfaction, retention, and loyalty benefits, as well as image improvements for managed care as a whole. Some simple and inexpensive options for both tracking and reminding consumers are offered for consideration, including personalized annual health reports.

2017-05-31

Dementia is a term used to describe a collection of symptoms that include problems with memory, self-care, reasoning and communication. Care interventions that focus on preserving people's dignity and identity are therefore essential. Using Driscoll's reflective model to guide critical thinking, this article reflects on the use of one intervention, namely life story work, to promote person-centred care for people with dementia. It explores the value or effect of life story work for healthcare staff, the person with dementia and family members. It also highlights best practice guidelines that are useful to consider to promote its optimal success as an intervention in dementia care, for example, instigating it early in the dementia journey and embedding it in a supportive culture. It is important to highlight to nursing students the many positive aspects of incorporating life story work into practice.

Double jeopardy and the veil of ignorance--a reply.

1995-06-01

This paper discusses the attempt in this issue of the journal by Peter Singer, John McKie, Helga Kuhse and Jeff Richardson, to defend QALYs against the argument from double jeopardy which I first outlined in 1987. In showing how the QALY and other similar measures which combine life expectancy and quality of life and use these to justify particular allocations of health care resource, remain vulnerable to the charge of double jeopardy I am able to clarify some of the central issues concerning the value of life. In particular, the idea that the value of a life varies with its life expectancy and with its quality, understood in terms of its richness, variety, success etc, is subjected to special examination. It is shown how defenders of QALYs are committed to the view that so far from all lives being of equal value, all lives are necessarily of subtly different value. The paper then analyses the use to which the notorious 'veil of ignorance' has been put both by Singer et al and by others and shows how this device of John Rawls's cannot do the work so often assigned to it. The paper then considers the issue of hypothetical consent and the role that it can play in justifying disposing of the lives of people who have not in fact consented to their lives being disposed of in particular ways. Finally, the paper makes some points about the comprehensive nature of the data collection and storage which would be required by QALY advocates and points out the independent problems attaching to licensing such comprehensive collection and use of personal data.

The effect of a patient's age on the social valuation of health services remains controversial, with empirical results varying in magnitude and implying a different age-value profile. This article employs a new methodology to re-examine these questions. Data were obtained from 2 independent Web-based surveys that administered the Relative Social Willingness to Pay instrument. In the first survey, the age of the patient receiving a life-saving service was varied. Patients were left with either poor mental or physical health. In the second survey, patient age was varied for a service that fully cured the patient's poor mental or physical health. In total, therefore, 4 sets of age weights were obtained: weights for life-extending services with poor physical or mental health outcomes and weights for quality-of-life improvement for patients in poor mental or physical health. Results were consistent. Increasing age was associated in each case with a monotonic decrease in the social valuation of the services. The decrease in value was quantitatively small until age 60 years. By age 80 years, the social value of services had declined by about 50%. The decline commenced at an earlier age in the context of physical health, although the magnitude of the decrement by age 80 years was unrelated to the type of service. With 1 exception, there was little difference in the valuation of services by the age of the survey respondent. Respondents aged >60 years placed a lower, not higher, value on quality-of-life improvement for elderly individuals than other respondents. There was no difference in the valuation of life-extending services.

In an otherwise healthy patient with severe facial disfigurement secondary to burns, composite tissue allotransplantation (CTA) results in life-long immunosuppressive therapy and its associated risk. In this study, we assess the net gain of CTA of face (in terms of utilities) from the perspectives of patient, general public and medical expert, in comparison to the risks. Using the standard gamble (SG) and time-trade off (TTO) techniques, utilities were obtained from members of general public, patients with facial burns, and medical experts (n=25 for each group). The gain (or loss) in utility and quality adjusted life years (QALY) were estimated using face-to-face interviews. A sensitivity analysis using variable life expectancy was conducted. From the patient perspective, severe facial burn was associated with a health utility value of 0.53, and 27.1 QALYs as calculated by SG, and a health utility value of 0.57, and 28.9 QALYs as calculated by TTO. In comparison, CTA of the face was associated with a health utility value of 0.64, and 32.3 QALYs (or 18.2 QALYs years per sensitivity analysis) as calculated by SG, and a health utility value of 0.67, and 34.1 QALYs (or 19.2QALYs per sensitivity analysis) as calculated by TTO. However, a loss of 8.9 QALYs (by SG method) to 9.5 QALYs (by TTO method) was observed when the life expectancy was decreased in the sensitivity analysis. Similar results were obtained from the general population and medical experts perspectives. We found that severe facial disfigurement is associated with a significant reduction in the health-related quality of life, and CTA has the potential to improve this. Further, we found that a trade-off exists between the life expectancy and gain in the QALYs, i.e. if life expectancy following CTA of face is reduced, the gain in QALY is also diminished. This trade-off needs to be validated in future studies. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

The measurement and valuation of quality of life forms a major component of economic evaluation in health care and is a major issue in health services research. However, differing approaches exist in the measurement and valuation of quality of life from a health economics perspective. While some instruments such as the EQ-5D-3L focus on health-related quality of life alone, others assess quality of life in broader terms, for example, the newly developed ICECAP-O. The aim of this study was to utilize two generic preference-based instruments, the EQ-5D-3L and the ICECAP-O, to measure and value the quality of life of older adult patients receiving post-acute care. An additional objective was to compare the values obtained by each instrument with those generated from two community-based general population samples. Data were collected from a clinical patient population of older adults receiving post-acute outpatient rehabilitation or residential transition care and two Australian general population samples of individuals residing in the general community. The individual responses to the ICECAP-O and EQ-5D-3L instruments were scored using recently developed Australian general population algorithms. Empirical comparisons were made of the resulting patient and general population sample values for the total population and dis-aggregated according to age (65-79 and 80+ years) and gender. A total of 1,260 participants aged 65-99 years (n = 86 clinical patient sample, n = 385 EQ-5D-3L general population sample, n = 789 ICECAP-O general population sample) completed one or both of the EQ-5D-3L and ICECAP-O instruments. As expected, the patient group demonstrated lower quality of life than the general population sample as measured by both quality-of-life instruments. The difference in values between the patient and general population groups was found to be far more pronounced for the EQ-5D-3L than for the ICECAP-O. The ICECAP-O was associated with a mean difference in values of 0.04 (patient group mean 0.753, SD 0.18; general population group mean 0.795, SD 0.17, respectively, p = 0.033). In contrast, the EQ-5D-3L was associated with a mean difference in values of 0.19 (patient group mean 0.595, SD 0.20; general population group mean 0.789, SD 0.02, respectively, p ≤ 0.001). The study findings illustrate the magnitude of the difference in patient and general population values according to the instrument utilized, and highlight the differences in both the theoretical underpinnings and valuation algorithms for the EQ-5D-3L and ICECAP-O instruments. Further empirical work is required in larger samples and alternative patient groups to investigate the generalizability of the findings presented here.

Quality of life (QoL) refers to the degree of satisfaction, or the sense of well being, people experience in organizations including universities. The quality of life students experience in a university increases when they believe their needs are aligned with the goals of the university because they perceive that the university is responsive to their needs. Quality of University Life (QuL) refers to the students' ability to stabilize their life regarding social activities, academic performance, health and spiritual. A study was undertaken to investigate the accountability of Universiti Teknologi MARA (UiTM), Malaysia, in terms of teaching and learning. The objective of this paper is to identify and evaluate the determinants of QoL and QuL measurement models. Data from 788 students who responded to a set of questionnaire were collected from nine faculties. Factor analysis performed on the data resulted in six determinants for QuL; friendly, skills, satisfaction, interest, learning and feeling. Only two determinants, environment and quality represented QoL. Results indicated that the measures were highly reliable (in terms of internal consistency) based on Cronbach Alpha values ranging from 0.705 to 0.905 for QuL and 0.826 to 0.888 for QoL. Construct validity was supported by Average Variance Extraction values of more than 0.5 for QuL (0.481 - 0.724) and QoL. (0.503 and 0.519). The construct reliability (CR) values ranging between 0.623 to 0.882 for QuL and 0.731 to 0.815 for QoL suggested good reliability construct.

Criteria used by the National Institute for Health and Care Excellence (NICE) to assess life-extending, end-of-life (EoL) treatments imply that health gains from such treatments are valued more than other health gains. Despite claims that the policy is supported by societal values, evidence from preference elicitation studies is mixed and in-depth research has shown there are different societal viewpoints. Few studies elicit preferences for policies directly or combine different approaches to understand preferences. Survey questions were designed to investigate support for NICE EoL guidance at national and regional levels. These 'Decision Rule' and 'Treatment Choice' questions were administered to an online sample of 1496 UK respondents in May 2014. The same respondents answered questions designed to elicit their agreement with three viewpoints (previously identified and described) in relation to provision of EoL treatments for terminally ill patients. We report the findings of these choice questions and examine how they relate to each other and respondents' viewpoints. The Decision Rule questions described three policies: DA - a standard 'value for money' test, applied to all health technologies; DB - giving special consideration to all treatments for terminal illnesses; and DC - giving special consideration to specific categories of treatments for terminal illnesses e.g. life extension (as in NICE EoL guidance) or those that improve quality-of-life (QoL). Three Treatment Choices were presented: TA - improving QoL for patients with a non-terminal illness; TB - extending life for EoL patients; and TC - improving QoL at the EoL. DC received most support (45%) with most respondents giving special consideration to EoL only when treatments improved QoL. The most commonly preferred treatment choices were TA (51%) and TC (43%). Overall, this study challenges claims about public support for NICE's EoL guidance and the focus on life extension at EoL and substantiates existing evidence of plurality in societal values.

2012-11-01

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.

This study was planned in an attempt to develop a scale for the quality of life in pediatric oncology patients aged 7-12, with child and parents forms. In collecting the study data, we used the Child and Parent Information Form, Visual Quality of Life Scale, Scale for Quality of Life Pediatric Oncology Patients Aged 7-12 and the Scale for the Quality of Life in Pediatric Oncology Patients Aged 7-12 for Parents. We also used Pearson correlation analysis, the Cronbach alpha coefficient, factor analysis and ROC analysis for the study data. In this study, the total Cronbach alpha value of the parent form was 0.96, the total factor load being 0.54-0.90 and the total variance explained was 82.5%. The cutoff point of the parent form was 93 points. The total Cronbach alpha value for the child form was 0.96, with a total factor load of 0.55-0.91 and the total variance being explained was 78.3%. The cutoff point of the child form was 65 points. This study suggests that the Scale for Quality of Life in Pediatric Oncology Patients Aged 7-12 Child and Parents Forms are valid and reliable instruments in assessing the quality of life of children.

A novel approach for calculating shelf life of minimally processed vegetables.

PubMed

Corbo, Maria Rosaria; Del Nobile, Matteo Alessandro; Sinigaglia, Milena

2006-01-15

Shelf life of minimally processed vegetables is often calculated by using the kinetic parameters of Gompertz equation as modified by Zwietering et al. [Zwietering, M.H., Jongenburger, F.M., Roumbouts, M., van't Riet, K., 1990. Modelling of the bacterial growth curve. Applied and Environmental Microbiology 56, 1875-1881.] taking 5x10(7) CFU/g as the maximum acceptable contamination value consistent with acceptable quality of these products. As this method does not allow estimation of the standard errors of the shelf life, in this paper the modified Gompertz equation was re-parameterized to directly include the shelf life as a fitting parameter among the Gompertz parameters. Being the shelf life a fitting parameter is possible to determine its confidence interval by fitting the proposed equation to the experimental data. The goodness-of-fit of this new equation was tested by using mesophilic bacteria cell loads from different minimally processed vegetables (packaged fresh-cut lettuce, fennel and shredded carrots) that differed for some process operations or for package atmosphere. The new equation was able to describe the data well and to estimate the shelf life. The results obtained emphasize the importance of using the standard errors for the shelf life value to show significant differences among the samples.

Static, Dynamic, and Fatigue Analysis of the Mechanical System of Ultrasonic Scanner for Inservice Inspection of Research Reactors

2018-02-01

This analysis is conducted to determine the effects of static and dynamic loads of the structure of mechanical system of Ultrasonic Scanner i.e., arm, column, and connection systems for inservice inspection of research reactors. The analysis is performed using the finite element method with 520 N static load. The correction factor of dynamic loads used is the Gerber mean stress correction (stress life). The results of the analysis show that the value of maximum equivalent von Mises stress is 1.3698E8 Pa for static loading and value of the maximum equivalent alternating stress is 1.4758E7 Pa for dynamic loading. These values are below the upper limit allowed according to ASTM A240 standards i.e. 2.05E8 Pa. The result analysis of fatigue life cycle are at least 1E6 cycle, so it can be concluded that the structure is in the high life cycle category.

Measuring quality of life in evaluating clinical interventions: an overview.

PubMed

Kind, P

2001-07-01

Health professionals provide care with some purpose in mind. It is reasonable to assume that they are therefore interested in observing and measuring health outcomes. In the recent past, it has become fashionable to describe health outcomes in terms of their impact on 'quality of life', a widely used term that is usually left undefined. Measures of health-related quality of life (HRQoL) are now in common usage in clinical studies. The construction of both generic and condition-specific measures of HRQoL relies heavily on the choice of descriptive domains, a process that often reflects the personal values of the developer of the instrument. Subjective valuation is a recurring phenomenon in the construction and application of HRQoL measures. These values should not be restricted to the private judgement of the clinician alone. The challenge for those evaluating clinical interventions is to make such values explicit and to extend the franchise to society as a whole.

2013-11-01

Acne is one of the most common dermatological diseases, and obsessive compulsive disorder is among the most frequent psychiatric conditions seen in dermatology clinics. Comorbidity of these conditions may therefore be expected. The aim of this study was to measure obsessive compulsive symptoms and quality of life in patients with acne vulgaris, compare them with those of healthy control subjects, and determine whether there is any predictive value of obsessive compulsive symptoms for quality of life in patients with acne. Obsessive compulsive symptoms and quality of life measurements of 146 patients with acne vulgaris and 94 healthy control subjects were made using the Maudsley Obsessive Compulsive Questionnaire and Short Form-36 in a cross-sectional design. Patients with acne vulgaris had lower scores for physical functioning, physical role dysfunction, general health perception, vitality, and emotional role dysfunction. They also had higher scores for checking, slowness, and rumination. The only predictor of physical functioning and vitality dimensions of health-related quality of life in these patients was rumination score. Obsessive compulsive symptoms in patients with acne vulgaris are higher than in controls, and this may correlate with both disease severity and quality of life for patients.

The economic value of innovative treatments over the product life cycle: the case of targeted trastuzumab therapy for breast cancer.

PubMed

Garrison, Louis P; Veenstra, David L

2009-01-01

Pharmacoeconomic analyses typically project the expected cost-effectiveness of a new product for a specific indication. This analysis develops a dynamic life-cycle model to conduct a multi-indication evaluation using the case of trastuzumab licensed in the United States for both early-stage and metastatic (or late-stage) human epidermal growth factor receptor 2 (HER2)-positive breast cancer therapy (early breast cancer [EBC]; metastatic breast cancer [MBC]), approved in 2006 and 1998, respectively. This dynamic model combined information on expected incremental cost-utility ratios for specific indications with an epidemiologically based projection of utilization by indication over the product life cycle-from 1998 to 2016. Net economic value was estimated as the cumulative quality-adjusted life years (QALYs) gained over the life cycle multiplied by a societal valuation of health gains ($/QALY) minus cumulative net direct treatment costs. Sensitivity analyses were performed under a range of assumptions. We projected that the annual number of EBC patients receiving trastuzumab will be more than three times that of MBC by 2016, in part because adjuvant treatment reduces the future incidence of MBC. Over this life cycle, the estimated overall incremental cost-effectiveness ratio (ICER) was $35,590/QALY with a total of 432,547 discounted QALYs gained. Under sensitivity analyses, the overall ICER varied from $21,000 to $53,000/QALY, and the projected net economic value resulting from trastuzumab treatment ranged from $6.2 billion to $49.5 billion. Average ICERs for multi-indication compounds can increase or decrease over the product life cycle. In this example, the projected overall life-cycle ICER for trastuzumab was less than one half of that in the initial indication. This dynamic perspective-versus the usual static one-highlights the interdependence of drug development decisions and investment incentives, raising important reimbursement policy issues.

Method of Fatigue-Life Prediction for an Asphalt Mixture Based on the Plateau Value of Permanent Deformation Ratio.

Sun, Yazhen; Fang, Chenze; Wang, Jinchang; Yuan, Xuezhong; Fan, Dong

2018-05-03

Laboratory predictions for the fatigue life of an asphalt mixture under cyclic loading based on the plateau value (PV) of the permanent deformation ratio (PDR) were carried out by three-point bending fatigue tests. The influence of test conditions on the recovery ratio of elastic deformation (RRED), the permanent deformation (PD) and PDR, and the trends of RRED, PD, and PDR were studied. The damage variable was defined by using PDR, and the relation of the fatigue life to PDR was determined by analyzing the damage evolution process. The fatigue equation was established based on the PV of PDR and the fatigue life was predicted by analyzing the relation of the fatigue life to the PV. The results show that the RRED decreases with the increase of the number of loading cycles, and the elastic recovery ability of the asphalt mixture gradually decreases. The two mathematical models proposed are based on the change laws of the RRED, and the PD can well describe the change laws. The RRED or the PD cannot well predict the fatigue life because they do not change monotonously with the fatigue life, and one part of the deformation causes the damage and the other part causes the viscoelastic deformation. The fatigue life decreases with the increase of the PDR. The average PDR in the second stage is taken as the PV, and the fatigue life decreases in a power law with the increase of the PV. The average relative error of the fatigue life predicted by the fatigue equation to the test fatigue life is 5.77%. The fatigue equation based on PV can well predict the fatigue life.

2018-05-01

Head and neck cancer (HNC) is a disease of older adults. Recurrent and metastatic head and neck squamous cell carcinoma portends a poor prognosis, with median overall survival of less than 12 months. Within this vulnerable population, significant treatment-related toxicities and physical and psychosocial sequelae can be devastating to quality of life at the end of life. Shared decision making and early comprehensive palliative and support services are at the crux of the approach to older adults with HNC. In doing so, low-value care that fails to meet the goals of patients and their caregivers at the end-of-life may be avoided. Copyright © 2018 Elsevier Inc. All rights reserved.

Wind velocity-change (gust rise) criteria for wind turbine design

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cliff, W.C.; Fichtl, G.H.

1978-07-01

A closed-form equation is derived for root mean square (rms) value of velocity change (gust rise) that occurs over the swept area of wind turbine rotor systems and an equation for rms value of velocity change that occurs at a single point in space. These formulas confirm the intuitive assumption that a large system will encounter a less severe environment than a small system when both are placed at the same location. Assuming a normal probability density function for the velocity differences, an equation is given for calculating the expected number of velocity differences that will occur in 1 hrmore » and will be larger than an arbitrary value. A formula is presented that gives the expected number of velocity differences larger than an arbitrary value that will be encountered during the design life of a wind turbine. In addition, a method for calculating the largest velocity difference expected during the life of a turbine and a formula for estimating the risk of exceeding a given velocity difference during the life of the structure are given. The equations presented are based upon general atmospheric boundary-layer conditions and do not include information regarding events such as tornados, hurricanes, etc.« less

Ethics of End of Life Decisions in Pediatrics: A Narrative Review of the Roles of Caregivers, Shared Decision-Making, and Patient Centered Values.

PubMed

Santoro, Jonathan D; Bennett, Mariko

2018-04-26

Background: This manuscript reviews unique aspects of end of life decision-making in pediatrics. Methods: A narrative literature review of pediatric end of life issues was performed in the English language. Results: While a paternalistic approach is typically applied to children with life-limiting medical prognoses, the cognitive, language, and physical variability in this patient population is wide and worthy of review. In end of life discussions in pediatrics, the consideration of a child’s input is often not reviewed in depth, although a shared decision-making model is ideal for use, even for children with presumed limitations due to age. This narrative review of end of life decision-making in pediatric care explores nomenclature, the introduction of the concept of death, relevant historical studies, limitations to the shared decision-making model, the current state of end of life autonomy in pediatrics, and future directions and needs. Although progress is being made toward a more uniform and standardized approach to care, few non-institutional protocols exist. Complicating factors in the lack of guidelines include the unique facets of pediatric end of life care, including physical age, paternalism, the cognitive and language capacity of patients, subconscious influencers of parents, and normative values of death in pediatrics. Conclusions: Although there have been strides in end of life decision-making in pediatrics, further investigation and research is needed in this field.

The shelf life extension of refrigerated grass carp (Ctenopharyngodon idellus) fillets by chitosan coating combined with glycerol monolaurate.

2017-08-01

A novel chitosan-based coating solution was prepared by combining glycerol monolaurate (GML) for shelf life extension of refrigerated grass carp fillets. The control and coated fillets were analyzed periodically for physicochemical (pH, thiobarbituric acid (TBA) value, total volatile basic nitrogen (TVB-N) value, K value, and shear force), microbiological (total viable counts (TVC), psychrophilic bacteria counts (PTC), Pseudomonads and H 2 S-producing bacteria) and sensorial characteristics. The results showed that chitosan-GML coated samples presented better quality preservation effects than chitosan coating alone. In addition, 2% chitosan enriched with 0.3% GML showed the significant (P<0.05) effectiveness in inhibiting microbial growth, nucleotide breakdown, the formation of alkaline components and texture deterioration, and maintaining sensory acceptability among the groups. These findings confirmed that chitosan coating enriched with GML was a promising method to extend the shelf life of refrigerated fillets. Copyright © 2017. Published by Elsevier B.V.

The reluctance to burden others as a value in end-of-life decision making: a source of inaccuracy in substituted judgment.

Most patients are decisionally incapacitated at the end of life, leaving final treatment decisions to proxies, whose substituted judgment is often inaccurate. We investigated the reluctance to burden others (RBO), a commonly cited patient value, as a possible source of proxy inaccuracy. In a sample of 202 elders and their proxies, elders responded to three burden-related questions and the Life-prolonging Treatment Preferences Questionnaire. Proxies used substituted judgment to respond to the same questions. Although RBO predicted treatment preferences for both elders and proxies, elders rated RBO significantly more important than did proxies. In addition, larger elder-proxy differences in RBO were associated with more inaccurate substituted judgment.

The incidence of fatality over the period 2010-2014 from automobile accidents in North Cyprus is 2.75 times greater than the average for the EU. With the prospect of North Cyprus entering the EU, many investments will need to be undertaken to improve road safety in order to reach EU benchmarks. The objective of this study is to provide local estimates of the value of a statistical life and injury along with the value of time savings. These are among the parameter values needed for the evaluation of the change in the expected incidence of automotive accidents and time savings brought about by such projects. In this study we conducted a stated choice experiment to identify the preferences and tradeoffs of automobile drivers in North Cyprus for improved travel times, travel costs, and safety. The choice of route was examined using mixed logit models to obtain the marginal utilities associated with each attribute of the routes that consumers choose. These estimates were used to assess the individuals' willingness to pay (WTP) to avoid fatalities and injuries and to save travel time. We then used the results to obtain community-wide estimates of the value of a statistical life (VSL) saved, the value of injury (VI) prevented, and the value per hour of travel time saved. The estimates for the VSL range from €315,293 to €1,117,856 and the estimates of VI from € 5,603 to € 28,186. These values are consistent, after adjusting for differences in incomes, with the median results of similar studies done for EU countries. Copyright © 2016 Elsevier Ltd. All rights reserved.

The monetary value of human lives lost due to neglected tropical diseases in Africa.

Neglected tropical diseases (NTDs) are an important cause of death and disability in Africa. This study estimates the monetary value of human lives lost due to NTDs in the continent in 2015. The lost output or human capital approach was used to evaluate the years of life lost due to premature deaths from NTDs among 10 high/upper-middle-income (Group 1), 17 middle-income (Group 2) and 27 low-income (Group 3) countries in Africa. The future losses were discounted to their present values at a 3% discount rate. The model was re-analysed using 5% and 10% discount rates to assess the impact on the estimated total value of human lives lost. The estimated value of 67 860 human lives lost in 2015 due to NTDs was Int$ 5 112 472 607. Out of that, 14.6% was borne by Group 1, 57.7% by Group 2 and 27.7% by Group 3 countries. The mean value of human life lost per NTD death was Int$ 231 278, Int$ 109 771 and Int$ 37 489 for Group 1, Group 2 and Group 3 countries, respectively. The estimated value of human lives lost in 2015 due to NTDs was equivalent to 0.1% of the cumulative gross domestic product of the 53 continental African countries. Even though NTDs are not a major cause of death, they impact negatively on the productivity of those affected throughout their life-course. Thus, the case for investing in NTDs control should also be influenced by the value of NTD morbidity, availability of effective donated medicines, human rights arguments, and need to achieve the NTD-related target 3.3 of the United Nations Sustainable Development Goal 3 (on health) by 2030.

Application of Pharmacokinetics and Pharmacodynamics in Product Life Cycle Management. A Case Study with a Carbidopa-Levodopa Extended-Release Formulation.

PubMed

Modi, Nishit B

2017-05-01

Increasing costs in discovering and developing new molecular entities and the continuing debate on limited company pipelines mean that pharmaceutical companies are under significant pressure to maximize the value of approved products. Life cycle management in the context of drug development comprises activities to maximize the effective life of a product. Life cycle approaches can involve new formulations, new routes of delivery, new indications or expansion of the population for whom the product is indicated, or development of combination products. Life cycle management may provide an opportunity to improve upon the current product through enhanced efficacy or reduced side effects and could expand the therapeutic market for the product. Successful life cycle management may include the potential for superior efficacy, improved tolerability, or a better prescriber or patient acceptance. Unlike generic products where bioequivalence to an innovator product may be sufficient for drug approval, life cycle management typically requires a series of studies to characterize the value of the product. This review summarizes key considerations in identifying product candidates that may be suitable for life cycle management and discusses the application of pharmacokinetics and pharmacodynamics in developing new products using a life cycle management approach. Examples and a case study to illustrate how pharmacokinetics and pharmacodynamics contributed to the selection of dosing regimens, demonstration of an improved therapeutic effect, or regulatory approval of an improved product label are presented.

An interspecies correlation model to predict acute dermal toxicity of plant protection products to terrestrial life stages of amphibians using fish acute toxicity and bioconcentration data.

2017-12-01

This paper presents a model to predict acute dermal toxicity of plant protection products (PPPs) to terrestrial amphibian life stages from (regulatory) fish data. By combining existing concepts, including interspecies correlation estimation (ICE), allometric relations, lethal body burden (LBB) and bioconcentration modelling, an equation was derived that predicts the amphibian median lethal dermal dose (LD 50 ) from standard acute toxicity values (96-h LC 50 ) for fish and bioconcentration factors (BCF) in fish. Where possible, fish BCF values were corrected to 5% lipid, and to parent compound. Then, BCF values were adjusted to an exposure duration of 96 h, in case steady state took longer to be achieved. The derived correlation equation is based on 32 LD 50 values from acute dermal toxicity experiments with 15 different species of anuran amphibians, comprising 15 different PPPs. The developed ICE model can be used in a screening approach to estimate the acute risk to amphibian terrestrial life stages from dermal exposures to PPPs with organic active substances. This has the potential to reduce unnecessary testing of vertebrates. Copyright © 2017 Elsevier Ltd. All rights reserved.

Incremental cost-effectiveness of laser therapy for choroidal neovascularization associated with histoplasmosis.

Brown, G C; Brown, M M; Sharma, S; Busbee, B; Brown, H

2000-01-01

Laser photocoagulation has been shown in a large clinical trial to be efficacious in reducing the degree of vision loss occurring secondary to choroidal neovascularization (CNV) associated with ocular histoplasmosis. Nevertheless, data are lacking concerning the impact of the therapy on quality of life and its value to stakeholders in health care. Recently, information concerning the utility value of visual states has become available. Accordingly, the authors undertook to ascertain the cost-effectiveness of laser photocoagulation for the treatment of extrafoveal CNV occurring in eyes with ocular histoplasmosis. Design--A computer simulation, econometric model is presented to evaluate the incremental cost-effectiveness of laser photocoagulation therapy, as compared with the natural course of the disease, for the treatment of patients with extrafoveal CNV associated with ocular histoplasmosis. The model applies long-term visual data from previous clinical trials, utility analysis (which reflects patient perceptions of quality of life), decision analysis with Markov modeling, and present value analysis with discounting to account for the time value of money. Outcome measure--Cost per quality-adjusted life-year gained from treatment. Laser photocoagulation therapy for extrafoveal CNV associated with ocular histoplasmosis costs $4167 1999 US dollars (at a 3% discount rate) for each quality-adjusted life-year gained from treatment. Sensitivity analysis shows that changing the discount rate substantially alters the cost-effectiveness, with a value of $1339 at a 0% discount rate and $56,250 at a 10% discount rate. Compared with therapeutic modalities for other disease entities, laser therapy for the treatment of extrafoveal CNV associated with ocular histoplasmosis appears to be a cost-effective treatment from the patient preference-based point of view.

A method for the inclusion of physical activity-related health benefits in cost-benefit analysis of built environment initiatives.

The built environment has a significant influence on population levels of physical activity (PA) and therefore health. However, PA-related health benefits are seldom considered in transport and urban planning (i.e. built environment interventions) cost-benefit analysis. Cost-benefit analysis implies that the benefits of any initiative are valued in monetary terms to make them commensurable with costs. This leads to the need for monetised values of the health benefits of PA. The aim of this study was to explore a method for the incorporation of monetised PA-related health benefits in cost-benefit analysis of built environment interventions. Firstly, we estimated the change in population level of PA attributable to a change in the built environment due to the intervention. Then, changes in population levels of PA were translated into monetary values. For the first step we used estimates from the literature for the association of built environment features with physical activity outcomes. For the second step we used the multi-cohort proportional multi-state life table model to predict changes in health-adjusted life years and health care costs as a function of changes in PA. Finally, we monetised health-adjusted life years using the value of a statistical life year. Future research could adapt these methods to assess the health and economic impacts of specific urban development scenarios by working in collaboration with urban planners.

To perform a value-based medicine analysis of clinical trials that evaluate the interventions of laser photocoagulation, intravitreal pegaptanib therapy, and photodynamic therapy (PDT) with verteporfin for the treatment of classic subfoveal choroidal neovascularization. Reference case cost-utility analysis using value-based medicine principles, which use patient-based utility values and standardized, input variable criteria. Data from participants in the Macular Photocoagulation Study, Pegaptanib for Neovascular Age-Related Macular Degeneration Study, and the Treatment of Age-Related Macular Degeneration with Photodynamic Therapy Study. Visual data were converted to a value-based format using time tradeoff utility analysis values from patients with macular degeneration. Costs were obtained from 2005 Medicare data. Outcomes (quality-adjusted life-years [QALYs]) and costs were discounted at a 3% annual rate. Interventional QALYs gained, percent improvement in quality of life, and dollars spent per QALY gained. Laser photocoagulation confers a 4.4% (P = 0.03 versus pegaptanib therapy) improvement in quality of life for the reference case, whereas pegaptanib therapy confers a 5.9% improvement and PDT confers an 8.1% (P = 0.0002 versus pegaptanib therapy) improvement. The cost-utility associated with laser photocoagulation is $8179, that for pegaptanib therapy is $66978, and that for PDT is $31544. All sensitivity analyses remain within the conventional standards of cost-effectiveness. Photodynamic therapy confers greater patient value than intravitreal pegaptanib therapy and laser photocoagulation for the treatment of classic subfoveal choroidal neovascularization. Despite the fact that laser photocoagulation is the most cost-effective intervention, both PDT and pegaptanib therapy deliver greater value, and thus are both preferred over laser photocoagulation. Using an economic measure, photodynamic therapy is the preferred treatment among these 3 interventions.

To determine which utility value assessment method is more suitable to evaluate changes in the quality of life due to dry eye symptoms. Dry eye outpatients with a presenting visual acuity of 20/25 or better in the worse-seeing eye were recruited. Presenting distance visual acuity, tear film break-up time, Schirmer I test and fluorescein were assessed. The severity of dry eye symptoms was assessed using the Ocular Surface Disease Index (OSDI), and utility values were measured using the time trade-off (TTO), standard gamble (SG1 and SG2) and rating scale (RS) methods. Different utility values were compared with each other. The most appropriate utility value method to evaluate quality-of-life changes solely due to dry eye symptoms is determined by calculating the correlation between the OSDI score and different utility values. A total of 104 patients were enrolled. The three sections of OSDI in the order of high to low scores were as follows: "environmental trigger," "eye discomfort" and "visual function." The utility scores measured with TTO, SG1, SG2 and RS were 0.95 ± 0.11, 0.96 ± 0.10, 0.99 ± 0.07 and 0.89 ± 0.10, respectively. The utility scores evaluated by the TTO, SG1, SG2 and RS methods were significantly different from each other (p < 0.05). Only the utility scores measured with RS were significantly correlated with the composite OSDI score, "environmental trigger" and "eye discomfort" section scores (p < 0.05). RS is more sensitive than TTO and SG for the evaluation of altered quality of life due to dry eye symptoms.

New analysis reexamines the value of cancer care in the United States compared to Western Europe.

Despite sharp increases in spending on cancer treatment since 1970 in the United States compared to Western Europe, US cancer mortality rates have decreased only modestly. This has raised questions about the additional value of US cancer care derived from this additional spending. We calculated the number of US cancer deaths averted, compared to the situation in Western Europe, between 1982 and 2010 for twelve cancer types. We also assessed the value of US cancer care, compared to that in Western Europe, by estimating the ratio of additional spending on cancer to the number of quality-adjusted life-years saved. Compared to Western Europe, for three of the four costliest US cancers-breast, colorectal, and prostate-there were approximately 67,000, 265,000, and 60,000 averted US deaths, respectively, and for lung cancer there were roughly 1,120,000 excess deaths in the study period. The ratio of incremental cost to quality-adjusted life-years saved equaled $402,000 for breast cancer, $110,000 for colorectal cancer, and $1,979,000 for prostate cancer-amounts that exceed most accepted thresholds for cost-effective medical care. The United States lost quality-adjusted life-years despite additional spending for lung cancer: -$19,000 per quality-adjusted life-year saved. Our results suggest that cancer care in the United States may provide less value than corresponding cancer care in Western Europe for many leading cancers.

Background: Work ability of nurses is an index of their job satisfaction and is a crucial factor in job quality and security. This study aimed to investigate the association between work ability and quality of working life and to determine the effective demographic and background variables, among nurses. Methods: The present study was conducted among nurses, working in educational hospitals under the supervision of Tehran University of Medical Sciences in 2014. Work Ability Index (WAI) and Work-related Quality of Life (WRQoL) were used. Results: The mean WAI was significantly associated with total WRQoL score and the two of its sub-items including Stress at Work, and General Well-Being (P-value=0.001). Moreover, the results showed a significant correlation between total WRQoL and WAI Subscales including mental resources (P-value=0.001), number of current diseases (P-value=0.02), and work ability in relation to the job demands (P-value=0.04). The WRQoL and WAI showed significant associations with age and job experience (P-value=0.001). The average score of WAI and WRQoL was statistically different among various working units (P-value=0.001). Conclusion: Overall, results support the association between nurses work ability and WRQoL. Monitoring the WRQoL and work ability of employees would help organizations to know their status and take measures to ameliorate the working conditions. PMID:29308385

Investing in a robotic milking system: a Monte Carlo simulation analysis.

PubMed

Hyde, J; Engel, P

2002-09-01

This paper uses Monte Carlo simulation methods to estimate the breakeven value for a robotic milking system (RMS) on a dairy farm in the United States. The breakeven value indicates the maximum amount that could be paid for the robots given the costs of alternative milking equipment and other important factors (e.g., milk yields, prices, length of useful life of technologies). The analysis simulates several scenarios under three herd sizes, 60, 120, and 180 cows. The base-case results indicate that the mean breakeven values are $192,056, $374,538, and $553,671 for each of the three progressively larger herd sizes. These must be compared to the per-unit RMS cost (about $125,000 to $150,000) and the cost of any construction or installation of other equipment that accompanies the RMS. Sensitivity analysis shows that each additional dollar spent on milking labor in the parlor increases the breakeven value by $4.10 to $4.30. Each dollar increase in parlor costs increases the breakeven value by $0.45 to $0.56. Also, each additional kilogram of initial milk production (under a 2x system in the parlor) decreases the breakeven by $9.91 to $10.64. Finally, each additional year of useful life for the RMS increases the per-unit breakeven by about $16,000 while increasing the life of the parlor by 1 yr decreases the breakeven value by between $5,000 and $6,000.

2018-01-01

Cost-utility analyses for acute myeloid leukemia (AML) require health state utility values (HSUVs) in order to calculate quality-adjusted life-years (QALYs) for each health state. This study reviewed AML-related HSUVs that could be used in economic evaluation studies. EMBASE, MEDLINE, and Cochrane databases were searched from January 2000 to November 2016 for relevant studies that reported quality of life (QoL) and HSUVs in AML. Identified relevant European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 values were mapped to HSUVs. HSUVs for each health state in the AML treatment pathway were then collated. Ten relevant studies were identified. Six were cost-effectiveness analyses utilizing HSUVs for calculation of QALYs, one was an effectiveness analysis (incremental QALY), and two were QoL studies reporting AML-specific utilities. An additional study reported QoL for patients undergoing stem cell transplantation (SCT). Since no study reported HSUVs for relapse, values from a study of secondary AML patients who failed prior treatment for myelodysplastic syndrome were used. Where multiple HSUVs were available, collected values were given priority over assumed values. AML treatment (induction, consolidation, or SCT) was associated with decreased HSUV, while post-treatment complete remission led to increased HSUV. There are some methodologically robust HSUVs that can be directly used in economic evaluations for AML. Careful interpretation is advised considering significant differences in methodologies and patient population (inclusion, size). We need to develop HSUVs with larger-sized studies, making greater use of condition-specific data.

The objective of our study was to clarify the impact of adverse events associated with the initial course of outpatient chemotherapy on the quality of life of breast cancer patients. We conducted a survey to assess the quality of life in 48 breast cancer patients before and after receiving their first course of outpatient chemotherapy at Gifu Municipal Hospital. Patients completed the European Quality of Life 5 Dimensions and Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs before and after 1 course of outpatient chemotherapy. European Quality of Life 5 Dimensions utility value and Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs total score decreased significantly after chemotherapy (p<0.001 and p = 0.018, respectively). The mean scores for the activity, physical condition, and psychological condition subscales of the Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs decreased significantly after chemotherapy (p = 0.003, p<0.001, and p = 0.032, respectively), whereas the social relationships score increased significantly (p<0.001). Furthermore, in the evaluation of quality of life according to individual adverse events, the decrease in quality of life after chemotherapy in terms of the European Quality of Life 5 Dimensions utility value and the Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs total score was greater in anorexic patients than in non-anorexic patients (p = 0.009 and p<0.001, respectively). This suggests that anorexia greatly reduces quality of life. Our findings reveal that anticancer drug-related adverse events, particularly anorexia, reduce overall quality of life following the first course of outpatient chemotherapy in current breast cancer patients. These findings are extremely useful and important in understanding the impact of anticancer drug-related adverse events on quality of life.

Value of public health and safety actions and radiation dose avoided

The values judged best to reflect the willingness of society to pay for the avoidance or reduction of risk were deduced from studies of costs of health care, transportation safety, consumer product safety, government agency actions, wage-risk compensation, consumer behavior (market) studies, and willingness-to-pay surveys. The results ranged from $1,400,000 to $2,700,000 per life saved. Applying the mean of these values ($2,100,000) and the latest risk per unit dose coefficients used by the ICRP (1991), which take into account risks to the general public, including genetic effects and nonfatal cancers, yields a value of dose avoided of $750 to $1,500more » per person-cSv for public exposures. The lower value applies if adjustments are made for years of life lost per fatality. A nominal value of $1,000 per person-cSv seems appropriate in light of the many uncertainties involved in deducing these values. These values are consistent with values recommended by several European countries for individual doses in the region of 1 mSv/y (100 mrem/y). Below this dose rate, most countries have values a factor of 7 to 10 lower, based on the assumption that society is less concerned with fatality risks below about 10{sup {minus}4}/y.« less

2016-11-01

A study was conducted to determine the resistance of OnDuty herbicide in paddy soil with different concentrations by using a broadleaf plant, Brassica juncea. The herbicide was used in the Clearfield® Production System that was adopted in Malaysia to overcome problems mainly caused by weedy rice. Evaluation of herbicide half-life was based on bioassay technique with different concentrations, i.e 0% (control), 50% (half dose), 100% (recommended dose) and 200% (double dose). The study was done in three replicates and followed the Complete Randomized Block Design (CRBD). Results showed that there was a correlation between the amount of herbicide doses and degradation period. The highest half-life value was shown by root inhibition in the double dose concentration of 33 days half-life, followed by the recommended dose with 23 days half-life. Meanwhile, the half dose treatment indicated a half-life value of 17 days for root and 11 days for shoot. Therefore, application of herbicides should follow the recommended dose as the degradation period will not be too long, hence providing maximum effectiveness of the herbicide to overcome weed infestation problems.

Advanced aircraft service life monitoring method via flight-by-flight load spectra

NASA Astrophysics Data System (ADS)

Lee, Hongchul

This research is an effort to understand current method and to propose an advanced method for Damage Tolerance Analysis (DTA) for the purpose of monitoring the aircraft service life. As one of tasks in the DTA, the current indirect Individual Aircraft Tracking (IAT) method for the F-16C/D Block 32 does not properly represent changes in flight usage severity affecting structural fatigue life. Therefore, an advanced aircraft service life monitoring method based on flight-by-flight load spectra is proposed and recommended for IAT program to track consumed fatigue life as an alternative to the current method which is based on the crack severity index (CSI) value. Damage Tolerance is one of aircraft design philosophies to ensure that aging aircrafts satisfy structural reliability in terms of fatigue failures throughout their service periods. IAT program, one of the most important tasks of DTA, is able to track potential structural crack growth at critical areas in the major airframe structural components of individual aircraft. The F-16C/D aircraft is equipped with a flight data recorder to monitor flight usage and provide the data to support structural load analysis. However, limited memory of flight data recorder allows user to monitor individual aircraft fatigue usage in terms of only the vertical inertia (NzW) data for calculating Crack Severity Index (CSI) value which defines the relative maneuver severity. Current IAT method for the F-16C/D Block 32 based on CSI value calculated from NzW is shown to be not accurate enough to monitor individual aircraft fatigue usage due to several problems. The proposed advanced aircraft service life monitoring method based on flight-by-flight load spectra is recommended as an improved method for the F-16C/D Block 32 aircraft. Flight-by-flight load spectra was generated from downloaded Crash Survival Flight Data Recorder (CSFDR) data by calculating loads for each time hack in selected flight data utilizing loads equations. From the comparison of interpolated fatigue life using CSI value and fatigue test results, it is obvious that proposed advanced IAT method via flight-by-flight load spectra is more reliable and accurate than current IAT method. Therefore, the advanced aircraft service life monitoring method based on flight-by-flight load spectra not only monitors the individual aircraft consumed fatigue life for inspection but also ensures the structural reliability of aging aircrafts throughout their service periods.

Flynn, Terry N; Louviere, Jordan J; Marley, Anthony AJ; Coast, Joanna; Peters, Tim J

2008-01-01

Background Researchers are increasingly investigating the potential for ordinal tasks such as ranking and discrete choice experiments to estimate QALY health state values. However, the assumptions of random utility theory, which underpin the statistical models used to provide these estimates, have received insufficient attention. In particular, the assumptions made about the decisions between living states and the death state are not satisfied, at least for some people. Estimated values are likely to be incorrectly anchored with respect to death (zero) in such circumstances. Methods Data from the Investigating Choice Experiments for the preferences of older people CAPability instrument (ICECAP) valuation exercise were analysed. The values (previously anchored to the worst possible state) were rescaled using an ordinal model proposed previously to estimate QALY-like values. Bootstrapping was conducted to vary artificially the proportion of people who conformed to the conventional random utility model underpinning the analyses. Results Only 26% of respondents conformed unequivocally to the assumptions of conventional random utility theory. At least 14% of respondents unequivocally violated the assumptions. Varying the relative proportions of conforming respondents in sensitivity analyses led to large changes in the estimated QALY values, particularly for lower-valued states. As a result these values could be either positive (considered to be better than death) or negative (considered to be worse than death). Conclusion Use of a statistical model such as conditional (multinomial) regression to anchor quality of life values from ordinal data to death is inappropriate in the presence of respondents who do not conform to the assumptions of conventional random utility theory. This is clearest when estimating values for that group of respondents observed in valuation samples who refuse to consider any living state to be worse than death: in such circumstances the model cannot be estimated. Only a valuation task requiring respondents to make choices in which both length and quality of life vary can produce estimates that properly reflect the preferences of all respondents.

Value Assessment at the Point of Care: Incorporating Patient Values throughout Care Delivery and a Draft Taxonomy of Patient Values.

PubMed

Armstrong, Melissa J; Mullins, C Daniel

2017-02-01

Incorporation of patient values is a key element of patient-centered care, but consistent incorporation of patient values at the point of care is lacking. Shared decision making encourages incorporation of patient values in decision making, but associated tools often lack guidance on value assessment. In addition, focusing on patient values relating only to specific decisions misses an opportunity for a more holistic approach to value assessment that could impact other aspects of clinical encounters, including health care planning, communication, and stakeholder involvement. In this commentary, we propose a taxonomy of values underlying patient decision making and provide examples of how these impact provision of health care. The taxonomy describes four categories of patient values: global, decisional, situational, and external. Global values are personal values impacting decision making at a universal level and can include value traits and life priorities. Decisional values are the values traditionally conceptualized in decision making, including considerations such as efficacy, toxicity, quality of life, convenience, and cost. Situational values are values tied to a specific moment in time that modify patients' existing global and decisional values. Finally, discussion of external values acknowledges that many patients consider values other than their own when making decisions. Recognizing the breadth of values impacting patient decision making has implications for both overall health care delivery and shared decision making because value assessments focusing only on decisional values may miss important patient considerations. This draft taxonomy highlights different values impacting decision making and facilitates a more complete value assessment at the point of care.

This study evaluated the lifetime future net tax revenues from individuals conceived after IVF relative to those naturally conceived. A model based on the method of generational accounting was developed to evaluate investments in IVF. Calculations were based on average investments paid and received from the government by an individual. All costs were discounted to their net present values and adjusted for survival. The lifetime net present value of IVF-conceived individuals was -€81,374 (the minus sign reflecting negative net present value). The lifetime net present value of IVF-conceived men and women were -€47,091 and -€123,177, respectively. The lifetime net present value of naturally conceived individuals was -€70,392; respective amounts for men and women were -€36,109 and -€112,195. The model was most sensitive to changes in the growth of healthcare costs, economic growth and the discount rate. Therefore, it is concluded that, similarly to naturally conceived individuals in the Netherlands, IVF-conceived individuals have negative discounted net tax revenue at the end of life. The analytic framework described here undervalues the incremental value of an additional birth because it only considers the fiscal consequences of life and does not take into consideration broader macroeconomic benefits.

To propose and test a new accelerated aging protocol for solid-state, small molecule pharmaceuticals which provides faster predictions for drug substance and drug product shelf-life. The concept of an isoconversion paradigm, where times in different temperature and humidity-controlled stability chambers are set to provide a critical degradant level, is introduced for solid-state pharmaceuticals. Reliable estimates for temperature and relative humidity effects are handled using a humidity-corrected Arrhenius equation, where temperature and relative humidity are assumed to be orthogonal. Imprecision is incorporated into a Monte-Carlo simulation to propagate the variations inherent in the experiment. In early development phases, greater imprecision in predictions is tolerated to allow faster screening with reduced sampling. Early development data are then used to design appropriate test conditions for more reliable later stability estimations. Examples are reported showing that predicted shelf-life values for lower temperatures and different relative humidities are consistent with the measured shelf-life values at those conditions. The new protocols and analyses provide accurate and precise shelf-life estimations in a reduced time from current state of the art.

Life of LED-Based White Light Sources

2005-09-01

Even though light-emitting diodes (LEDs) may have a very long life, poorly designed LED lighting systems can experience a short life. Because heat at the p-n-junction is one of the main factors that affect the life of the LED, by knowing the relationship between life and heat, LED system manufacturers can design and build long-lasting systems. In this study, several white LEDs from the same manufacturer were subjected to life tests at different ambient temperatures. The exponential decay of light output as a function of time provided a convenient method to rapidly estimate life by data extrapolation. The life of these LEDs decreases in an exponential manner with increasing temperature. In a second experiment,several high-power white LEDs from different manufacturers were life-tested under similar conditions. Results show that the different products have significantly different life values.

The aim of this study was to evaluate the long-term clinical and economic outcomes associated with exenatide or insulin glargine, added to oral therapy in individuals with type 2 diabetes inadequately controlled with combination oral agents in the UK setting. A published and validated computer simulation model of diabetes was used to project long-term complications, life expectancy, quality-adjusted life expectancy and direct medical costs. Probabilities of diabetes-related complications were derived from published sources. Treatment effects and patient characteristics were extracted from a recent randomised controlled trial comparing exenatide with insulin glargine. Simulations incorporated published quality of life utilities and UK-specific costs from 2004. Pharmacy costs for exenatide were based on 20, 40, 60, 80 and 100% of the US value (as no price for the UK was available at the time of analysis). Future costs and clinical benefits were discounted at 3.5% annually. Sensitivity analyses were performed. In the base-case analysis exenatide was associated with improvements in life expectancy of 0.057 years and in quality-adjusted life expectancy of 0.442 quality-adjusted life years (QALYs) versus insulin glargine. Long-term projections demonstrated that exenatide was associated with a lower cumulative incidence of most cardiovascular disease (CVD) complications and CVD-related death than insulin glargine. Using the range of cost values, evaluation results showed that exenatide is likely to fall in a range between dominant (cost and life saving) at 20% of the US price and cost-effective (with an ICER of 22,420 pounds per QALY gained) at 100% of the US price, versus insulin glargine. Based on the findings of a recent clinical trial, long-term projections indicated that exenatide is likely to be associated with improvement in life expectancy and quality-adjusted life expectancy compared to insulin glargine. The results from this modelling analysis suggest that that exenatide is likely to represent good value for money by generally accepted standards in the UK setting in individuals with type 2 diabetes inadequately controlled on oral therapy.

Advanced Life Support System Value Metric

NASA Technical Reports Server (NTRS)

Jones, Harry W.; Rasky, Daniel J. (Technical Monitor)

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 led to the following approach. 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 considered to be exactly equal. This is too simplistic. Actual system design concepts are selected using many cost and benefit factors and the system specification is defined after many trade-offs. 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/[ESM + function (TRL)], with appropriate weighting and scaling. The total value is given by SVM. Cost is represented by higher ESM and lower TRL. The paper provides a detailed description and example application of a suggested System Value Metric and an overall ALS system metric.

Recently, high strength tungsten (W) alloyed steels have been developed for use in power plants with higher steam conditions for environmental reasons as well as the improvement of thermal efficiency resulting in lower fuel costs. In order to establish a creep modeling of high strength martensitic steel and to understand the basic role of W in tungsten alloyed 9-12Cr steels, conventional martensitic steels (X20CrMoV121, X20CrMoWV121, and Mod9Cr-1Mo) and tungsten alloyed steels (NF616 and HCM12A) were employed for creep tests and creep behavior analyses by the Ω method. The proposed creep model, which takes into account both primary and tertiary creep, satisfactorily described the creep curves and accurately predicted creep life, as martensitic steel undergoes a relatively large amount of primary creep, up to nearly 30%, over its normal life. The tungsten alloyed steels exhibited a smaller minimum creep rate and a larger stress exponent compared to the conventional steels. In addition, in tungsten alloyed steel, the Ω value features strong stress dependence such that creep life is prolonged at lower stresses due to high Ω values. The importance of the Ω value from the standpoint of creep strengthening in primary and tertiary creep is discussed.

Years of Life Lost Due to External Causes of Death in the Lodz Province, Poland

2014-01-01

Background The aim of the study is the analysis of years of life lost due to external causes of death, particularly due to traffic accidents and suicides. Materials and Methods The study material includes a database containing information gathered from 376,281 death certificates of inhabitants of the Lodz province who died between 1999 and 2010. The Lodz province is characterized by the highest mortality rates in Poland. The SEYLLp (Standard Expected Years of Life Lost per living person) and the SEYLLd (per death) indices were used to determine years of life lost. Joinpoint models were used to analyze time trends. Results In 2010, deaths due to external causes constituted 6.0% of the total number of deaths. The standardized death rate (SDR) due to external causes was 110.0 per 100,000 males and was five times higher than for females (22.0 per 100,000 females). In 2010, the SEYLLp due to external causes was 3746 per 100,000 males and 721 per 100,000 females. Among males, suicides and traffic accidents were the most common causes of death (the values of the SEYLLp were: 1098 years and 887 years per 100,000 people, respectively). Among females, the SEYLLp values were 183 years due to traffic accidents and 143 years due to suicides (per 100,000 people). Conclusions A decrease in the number of years of life lost due to external causes is much higher among females. The authors observe that a growing number of suicides contribute to an increase in the value of the SEYLLp index. This directly contributes to over-mortality of males due to external causes. The analysis of the years of life lost focuses on the social and economic aspects of premature mortality due to external causes. PMID:24810942

Systematic review of the impact of urinary tract infections on health-related quality of life.

2012-12-01

What's known on the subject? and What does the study add? Values for equivalent health states can vary substantially depending on the measure used and method of valuation; this has a direct impact on the results of economic analyses. To date, the majority of existing economic evaluations that include UTI as a health state refer to an analysis in which the Index of Well Being was used to estimate the quality of life experienced by young women with UTIs. Currently, there are no validated methods or filters for systematically searching for the type of generic quality of life data required for decision analytic models. This study is the only systematic review of quality of life in people with UTI in the literature. Twelve studies were identified which report quality of life using a variety of generic methods; the results of these papers were summarized in a way that is useful for a health researcher seeking to populate a decision model, design a clinical study or assess the effect of UTI on quality of life relative to other conditions. One research group provided previously unpublished data from a large cohort study; these scores were mapped to EuroQol 5-Dimension values using published algorithms and probabilistic simulations. The aim of this review was to identify studies that have evaluated the impact of symptomatic urinary tract infection (UTI) and UTI-associated bacteraemia on quality of life, and to summarize these data in a way that is useful for a health researcher seeking to populate a cost-utility model, design a clinical study or assess the effect of UTIs on quality of life relative to other conditions. We conducted a systematic search of the literature using MEDLINE, EMBASE, the NHS Economic Evaluations database, Health Technology Assessment database, Health Economics Evaluations database, Cost-Effectiveness Analysis Registry and EuroQol website. Studies that reported utility values for symptomatic UTI or UTI-associated bacteraemia derived from a generic QoL measurement tool or expert opinion were included. Studies using disease-specific instruments were excluded. Twelve studies were identified that included a generic measure of health-related quality of life for patients with UTIs. These measures included: the short-form (SF)-36 and SF-12 questionnaires; the Health Utilities Index Mark 2; Quality of Well Being; the Index of Well Being, standard gamble; the Health and Activity Limitation Index; and expert opinion. The authors of studies using either of the SF questionnaires were contacted for additional data. One research group provided previously unpublished data from a large cohort study; these scores were mapped to EuroQol 5-Dimension (EQ-5D) values using published algorithms and probabilistic simulations. The present review provides health researchers with several sources from which to select utility values to populate cost-utility models. It also shows that very few studies have measured quality of life in patients with UTI using generic preference-based measures of health and none have evaluated the impact of this health state on quality of life in children. Future studies ought to consider the inclusion of commonly used preference-based measures of health, such as the EQ-5D, in all patient populations experiencing symptomatic UTI or UTI-related complications. © 2012 NATIONAL CLINICAL GUIDELINE CENTRE OF ROYAL COLLEGE OF PHYSICIANS.

To use contingent valuation (CV) to derive individual consumer values for both health and broader benefits of a public-health intervention directed at lifestyle behaviour change (LBC) and to examine the feasibility and validity of the method. Participants of a lifestyle intervention trial (n = 515) were invited to complete an online CV survey. Respondents (n = 312) expressed willingness to invest money and time for changes in life expectancy, health-related quality of life (HRQOL) and broader quality of life aspects. Internal validity was tested for by exploring associations between explanatory variables (i.e. income, paid work, experience and risk factors for cardiovascular diseases) and willingness to invest, and by examining ordering effects and respondents' sensitivity to the scope of the benefits. The majority of respondents (94.3%) attached value to benefits of LBC, and 87.4% were willing to invest both money and time. Respondents were willing to invest more for improvements in HRQOL (€42/month; 3 h/week) and broader quality of life aspects (€40/month; 2.6 h/week) than for improvements in life expectancy (€24/month; 2 h/week). Protest answers were limited (3%) and findings regarding internal validity were mixed. The importance of broader quality of life outcomes to consumers suggests that these outcomes are relevant to be considered in the decision making. Our research showed that CV is a feasible method to value both health and broader outcomes of LBC, but generalizability to other areas of public health still needs to be examined. Mixed evidence regarding internal validity pleads for caution to use CV as only the base for decision making. © 2014 John Wiley & Sons Ltd.

Human neutrophils have traditionally been thought to have a short half-life in blood; estimates vary from 4 to 18 hours. This dogma was recently challenged by stable isotope labeling studies with heavy water, which yielded estimates in excess of 3 days. To investigate this disparity, we generated new stable isotope labeling data in healthy adult subjects using both heavy water (n = 4) and deuterium-labeled glucose (n = 9), a compound with more rapid labeling kinetics. To interpret results, we developed a novel mechanistic model and applied it to previously published (n = 5) and newly generated data. We initially constrained the ratio of the blood neutrophil pool to the marrow precursor pool (ratio = 0.26; from published values). Analysis of heavy water data sets yielded turnover rates consistent with a short blood half-life, but parameters, particularly marrow transit time, were poorly defined. Analysis of glucose-labeling data yielded more precise estimates of half-life (0.79 ± 0.25 days; 19 hours) and marrow transit time (5.80 ± 0.42 days). Substitution of this marrow transit time in the heavy water analysis gave a better-defined blood half-life of 0.77 ± 0.14 days (18.5 hours), close to glucose-derived values. Allowing the ratio of blood neutrophils to mitotic neutrophil precursors (R) to vary yielded a best-fit value of 0.19. Reanalysis of the previously published model and data also revealed the origin of their long estimates for neutrophil half-life: an implicit assumption that R is very large, which is physiologically untenable. We conclude that stable isotope labeling in healthy humans is consistent with a blood neutrophil half-life of less than 1 day. © 2016 by The American Society of Hematology.

Diabetes mellitus disease is one of the chronic diseases which can cause a fatal risk if its management is not appropriate. The purpose of this study was to determine the relationship between perception and quality of life in Dok II Jayapura hospital. This study used an observational research design with cross sectional approach with prospective sampling in diabetic patients in internal disease policemen who were underwent outpatient treatment at Dok II Jayapura hospital. Research instruments used EQ-5D (European Quality-5 Dimension) and B-IPQ (Brief Illness Perception Quetionare). Data analysis used was univariate analysis by using percentage or mean value, bivariate using T-test or Mann-Whitney test, and multivariate using multiple linear regression. There were 80 T2DM patients who met the inclusion criteria. Based on patient demographic data, there were 29 people (36.6%) male patients and 51 people (63.8%) female patients, with mean age of patient (55.79±10.52) year. Perception has correlation with quality of life influenced by index value on treatment control (6.73±1.475) and emotional response (3.11±2.199) and by visual analog scale on understanding (5.99±1.587), duration (6.50±2.968), and personal controls (6.20±1.641). Based on the results obtained to improve the quality of life of T2DM patients that is on the index value on the control of treatment and emotional response and on visual analog scale on the understanding, duration and personal control should be changed so that the quality of life of patients increases. The family history, social status and type of treatment factors also affect the quality of life.

Predicting pedestrian flow: a methodology and a proof of concept based on real-life data.

PubMed

Davidich, Maria; Köster, Gerta

2013-01-01

Building a reliable predictive model of pedestrian motion is very challenging: Ideally, such models should be based on observations made in both controlled experiments and in real-world environments. De facto, models are rarely based on real-world observations due to the lack of available data; instead, they are largely based on intuition and, at best, literature values and laboratory experiments. Such an approach is insufficient for reliable simulations of complex real-life scenarios: For instance, our analysis of pedestrian motion under natural conditions at a major German railway station reveals that the values for free-flow velocities and the flow-density relationship differ significantly from widely used literature values. It is thus necessary to calibrate and validate the model against relevant real-life data to make it capable of reproducing and predicting real-life scenarios. In this work we aim at constructing such realistic pedestrian stream simulation. Based on the analysis of real-life data, we present a methodology that identifies key parameters and interdependencies that enable us to properly calibrate the model. The success of the approach is demonstrated for a benchmark model, a cellular automaton. We show that the proposed approach significantly improves the reliability of the simulation and hence the potential prediction accuracy. The simulation is validated by comparing the local density evolution of the measured data to that of the simulated data. We find that for our model the most sensitive parameters are: the source-target distribution of the pedestrian trajectories, the schedule of pedestrian appearances in the scenario and the mean free-flow velocity. Our results emphasize the need for real-life data extraction and analysis to enable predictive simulations.

[Policy decisions from a societal perspective: local or national evaluation of health related quality of life not necessary].

PubMed

Buskens, E

2005-07-09

Research among a sample of the Dutch population has shown that different relative values are assigned to some of the five sub-domains of the 'Euro-Quality of life, five dimensions' (EQ-5D) questionnaire when compared to the current English values. These findings might be interpreted as proof that the resulting 'tariffs' should also differ across countries. Conversely, one could argue that the current Oxford tariffs are simply inadequate. Clearly, decisions for individual patients should be based on the individual's preferences. However, policy decisions taken from a societal perspective should be based on a global value system. It would seem that a single Western European tariff would be preferable to a whole range of national tariffs.

Achieving high value care for all and the perverse incentives of 340B price agreements.

PubMed

Whittington, Melanie D; Campbell, Jonathan D; McQueen, R Brett

2018-04-01

Section 340B of the Public Health Service Act requires drug manufacturers to enter into price agreements with the Department of Health and Human Services. These agreements result in variation in the price paid to acquire a drug by sector, which complicates the price used in cost-effectiveness analyses. We describe the transactions and sectors in a 340B agreement using a multiple sclerosis drug. Cost-effectiveness estimates were calculated for the drug using drug prices from the manufacturer and payer perspective. We found the amount paid to the manufacturer (340B price) was a good value ($118,256 per quality-adjusted life-year); however, from the payer drug cost perspective, good value ($196,683 per quality-adjusted life-year) was not achieved. Given that emerging value frameworks incorporate cost-effectiveness, these price variations may have downstream negative consequences, including inaccurate coverage and reimbursement policy recommendations. Upcoming policy changes to the 340B program should incentivize pricing schemes hinged on transparency and value.

Experiences of spirituality and spiritual values in the context of nursing - an integrative review.

PubMed

Rudolfsson, Gudrun; Berggren, Ingela; da Silva, António Barbosa

2014-01-01

Spirituality is often mistakenly equated with religion but is in fact a far broader concept. The aim of this integrative review was to describe experiences of the positive impact of spirituality and spiritual values in the context of nursing. The analysis was guided by Whittemore and Knafl's integrative review method. The findings revealed seven themes: 'Being part of a greater wholeness', 'Togetherness - value based relationships', 'Developing inner strength', 'Ministering to patients', 'Maintaining one's sense of humanity', 'Viewing life as a gift evokes a desire to 'give back'' and 'Achieving closure - life goes on'. It is difficult to draw definite conclusions, as spirituality involves many perspectives on various levels of awareness. However, spirituality was considered more inclusive, fluid and personal. Furthermore, it emerged that spirituality and spiritual values in the context of nursing are closely intertwined with the concept of caring.

Rebranding exercise: closing the gap between values and behavior

PubMed Central

2011-01-01

Background Behavior can only be understood by identifying the goals to which it is attached. Superordinate-level goals are linked to individuals' values, and may offer insights into how to connect exercise with their core values and increase participation in sustainable ways. Methods A random sample of healthy midlife women (aged 40-60y) was selected to participate in a year-long mixed-method study (n = 226). Superordinate goals were measured inductively and analyzed using grounded theory analysis. Attainment Value and Exercise Participation were quantitatively measured. An ANOVA and pairwise comparisons were conducted to investigate the differences between superordinate exercise goals in attainment value. This study fit a Linear Mixed Model to the data to investigate the fixed effects of superordinate goals on exercise participation, controlling for BMI and social support. Results Participants mainly exercised to achieve Healthy-Aging, Quality-of-Life, Current-Health, and Appearance/Weight superordinate goals. Despite equally valuing Healthy-Aging, Quality-of-Life, and Current-Health goals, participants with Quality-of-Life goals reported participating in more exercise than those with Current-Health (p < 0.01), and Healthy-Aging (p = 0.06) goals. Conclusions Superordinate exercise goals related to health and healthy aging are associated with less exercise than those related to enhancing daily quality of life, despite being equally valued. While important, pursuing distant benefits from exercise such as health promotion, disease prevention, and longevity might not be as compelling to busy individuals compared to their other daily priorities and responsibilities. By shifting our paradigm from medicine to marketing, we can glean insights into how we can better market and "sell" exercise. Because immediate payoffs motivate behavior better than distant goals, a more effective "hook" for promoting sustainable participation might be to rebrand exercise as a primary way individuals can enhance the quality of their daily lives. These findings have important implications for how we as a culture, especially those in fitness-related businesses, health promotion, health care, and public health, prescribe and market exercise on individual and population levels.

High-precision measurements of the half-life and β-branching ratios for the β- decay of 26Na to 26Mg have been measured in β-counting and γ-decay experiments, respectively. A 4π proportional counter and fast tape transport system were employed for the half-life measurement, whereas the γ rays emitted by the daughter nucleus 26Mg were detected with the 8π γ-ray spectrometer, both located at TRIUMF's isotope separator and accelerator radioactive beam facility. The half-life of 26Na was determined to be T1/2=1.07128±0.00013±0.00021s, where the first error is statistical and the second systematic. The logft values derived from these experiments are compared with theoretical values from a full sd-shell model calculation.

To describe comparative effectiveness and assess its role in crafting new healthcare policy. Senate Bill S.3408 would establish a nongovernment-affiliated Healthcare Comparative Effectiveness Research Institute that would work with healthcare experts and stakeholders in healthcare to prioritize interventions and services to be studied. A value-based medicine system of standardized comparative effectiveness and cost-effectiveness data using utilities would allow physicians to assess the total value (improvement in quality of life and/or length of life) conferred by interventions. Standardized comparativeness and cost-effectiveness data will give physicians an information system to identify the interventions that confer the greatest value to patients, and thus deliver higher quality care than possible with evidence-based data alone while allowing the most cost-effective care.

Evidence base medicine (EBM) is based on objective evidence, which provides best available knowledge for physicians to scientifically make medical and therapeutic decisions for the care of all individual patients in order to improve the effectiveness of treatment and to prolong the life of patients. EBM has made a significant progress in clinical practice. But medical therapies cannot always bring a better life quality and clinically, patients' preference should be always taken into account. Value-based medicine medicine (VBM) is the practice of medicine that emphasizes the value received from an intervention. It takes evidence-based data to a higher level by combining the parameters of patient-perceived value with the cost of an intervention. The fundamental instrument of VBM is cost-utility analysis. VBM will provide a better practice model to evaluate the therapeutic package and cost effectiveness for individual and general health care.

Harris levels two main criticisms against our original defence of QALYs (Quality Adjusted Life Years). First, he rejects the assumption implicit in the QALY approach that not all lives are of equal value. Second, he rejects our appeal to Rawls's veil of ignorance test in support of the QALY method. In the present article we defend QALYs against Harris's criticisms. We argue that some of the conclusions Harris draws from our view that resources should be allocated on the basis of potential improvements in quality of life and quantity of life are erroneous, and that others lack the moral implications Harris claims for them. On the other hand, we defend our claim that a rational egoist, behind a veil of ignorance, could consistently choose to allocate life-saving resources in accordance with the QALY method, despite Harris's claim that a rational egoist would allocate randomly if there is no better than a 50% chance of being the recipient.

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

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

Morals and markets.

PubMed

Falk, Armin; Szech, Nora

2013-05-10

The possibility that market interaction may erode moral values is a long-standing, but controversial, hypothesis in the social sciences, ethics, and philosophy. To date, empirical evidence on decay of moral values through market interaction has been scarce. We present controlled experimental evidence on how market interaction changes how human subjects value harm and damage done to third parties. In the experiment, subjects decide between either saving the life of a mouse or receiving money. We compare individual decisions to those made in a bilateral and a multilateral market. In both markets, the willingness to kill the mouse is substantially higher than in individual decisions. Furthermore, in the multilateral market, prices for life deteriorate tremendously. In contrast, for morally neutral consumption choices, differences between institutions are small.

Based on the Effort-Reward-Imbalance Model by Siegrist a study was undertaken to find out (a) in what way young doctors assess effort and reward during their specialist training; (b) whether there are certain job stress patterns over time; and (c) what the correlations are, if any, between perceived job stress, health and satisfaction with life. Within the framework of a prospective study (2001 - 2007) 370 doctors who had just qualified and were residents in the German-speaking part of Switzerland were assessed four times by means of anonymized questionnaires. Job stress, measured by the Effort-Reward-Imbalance scale, as well as health and satisfaction with life were assessed in these doctors' 2nd (T2), 4th (T3), and 6th (T4) year of specialist training ("residents"). Stress patterns of the participants were evaluated, based on the effort and reward scale values at T2, T3, and T4, by two-step cluster analysis. Gender differences between the clusters were calculated by the 2 test and differences in the continuous variables by analysis of variance with repeated measurements. During residency the percentage of doctors who experienced an Effort-Reward-Imbalance (ratio between effort and reward ERI > 1) increased from 18% at T2 to 20 % at T3 to 25 % at T4. The cluster analysis revealed two clusters: Type 1 (67%) with effort values below average and reward values above average (ER balance) across the three measurement points, and type 2 (33 %) with effort values above average and reward values below average (ER imbalance). Subjects in cluster 2 showed unfavorable values, when compared with those in cluster 1, in overcommitment, in workload and in the health variables (anxiety, depression, physical and psychological well-being), as well as in their assessed satisfaction with life at all three measurement points. One third of the doctors experienced stress at work, caused by an effort-reward imbalance. This had a negative impact on their health and satisfaction with life. Regular supervision and goal-oriented career counselling provided by senior physicians could contribute to young doctors not feeling so much stressed at work, feeling well and being more content with their work.

Life history reconstruction of modern and fossil sockeye salmon ( Oncorhynchus nerka) by oxygen isotopic analysis of otoliths, vertebrae, and teeth: Implication for paleoenvironmental reconstructions

We evaluate the use of oxygen isotope values of biogenic apatite for tracking freshwater to marine migration in modern and fossil Pacific sockeye salmon. Oxygen isotope analyses of otoliths, vertebrae, and teeth of three anadromous modern sockeye salmon from Alaska establish a basis for the interpretation of fossil vertebrae and tooth apatite from Pleistocene sockeye salmon of the Skokomish River Valley, Washington. High resolution δ18O profiles in salmon otoliths provide, at a monthly resolution, a detailed record of individual history including continental rearing, migration to sea, seasonal variation in sea surface temperatures during marine life, and spawning migration before capture. Pacific salmon teeth are constantly renewed with the last set of teeth forming under the influence of freshwater. Therefore, they do not allow inference concerning sea-run versus landlocked life history in fossil salmon. Salmon vertebrae are also ambiguous indicators of life history regarding fresh versus marine water because centra are minimally ossified in the freshwater stages of life and the outermost layer of vertebral bone might be resorbed to provide nutrients during the non-feeding phase of the spawning migration. Therefore, δ18O values of accretionary growth rings in sea-run salmon vertebrae are dominated by the marine signal only if they are not diagenetically altered in freshwater deposits. In Pleistocene sockeye reported here, neither the teeth nor vertebral apatite present clear marine δ18O values due to the combined effects of tooth replacement and diagenetic alteration of bone and dentine. δ18O(PO 4) values of fossil vertebrae are intermediate between δ18O(PO 4) values of enamel and basal tooth dentin. Assuming a similar rate of isotope exchange of vertebrae and dentine with freshwater during diagenesis, these results are interpreted to reflect formation of the teeth under the influence of freshwater, and formation of the vertebrae under the influence of oceanic water. Our approach demonstrates that when appropriate knowledge of tissue formation is available, isotopic differences between altered and unaltered tissue holds promise of distinguishing between marine and freshwater origin of the tissues.

Physical activity, psychosocial health, and life goals among youth.

The main goal of the present study is to investigate the relationship between youth's physical activity, their psychosocial health and well-being, and their life goals. Data were collected among students (n = 1109, age range between 14 and 21 years of age, mean: 16.5 years, SD = 1.3 years) enrolled in the secondary schools of the Southern Plain Region (three counties), Hungary. Our findings support previous results that more active students have a better self-perceived health and fitness, lower levels of depressive symptoms and higher levels of life satisfaction. In addition, students who are regularly active prefer less extrinsic values as life goals for their future. However, there are no significant differences by physical activity status in terms of intrinsic values (except for physical health). These findings suggest that physical activity is not per se a beneficial health behavior only through its functions. In community health programs, a health-related physical education approach should be addressed to improve the psychosocial benefits of physical activity.

Life and Job Satisfaction as Predictors of the Incidence of Diabetes.

Shirom, Arie; Toker, Sharon; Melamed, Samuel; Berliner, Shlomo; Shapira, Itzhak

2012-03-01

We studied the hypothesised effects of baseline levels of life satisfaction and of job satisfaction on the incidence of diabetes. Participants were 2,305 apparently healthy men and women who underwent routine health checks at two points in time, about 20 months apart. New cases of diabetes (N=104) were defined based on fasting glucose value > 125, or glycosylated hemoglobin value > 6.5, or self-reported physician diagnosis of diabetes and taking medications to treat it. Life satisfaction was measured using the scale constructed by Diener et al. (1985) while job satisfaction was assessed based on the Survey of Working Conditions. In the analyses, we controlled for socio-demographic predictors, for known physiological and behavioral precursors of diabetes, and for depressive symptoms. There was support for our hypothesis that the higher the baseline levels of life satisfaction, the lower the incidence of diabetes. However, job satisfaction did not predict the incidence of diabetes. We obtained the same results when limiting the analysis to new cases of diabetes based on objective criteria only and when using as predictors both life and job satisfaction. We suggest that life satisfaction could be a protective factor reducing the risk of diabetes. © 2011 The Authors.

Esthetics is an important part of quality of life and a frequent reason for orthodontic treatment demand. It was the aim of this study to investigate whether esthetic impairments, related to overjet and overbite, can be assessed with an established oral health-related quality of life instrument. Data from 1968 participants (age: 16-90 years; 69.8% female) from three German surveys were analyzed. Esthetic impairments of oral health-related quality of life were measured with four questions of the Oral Health Impact profile (OHIP), which comprise esthetic aspects of oral health-related quality of life. Higher values represent greater esthetic impairment (sum score: 0-16). Overbite and overjet values were categorized (≤ - 1 mm, 0-1 mm, 2-3 mm, 4-5 mm, ≥ 6 mm). The specific impact of each category on esthetic impairment, in relation to the reference category (2-3 mm), was calculated in linear regression analyses. The type of relationship and the specific impact of overbite and overjet were evaluated in regression analyses with fractional polynomials. Overbite ranged from - 5 to 15 mm (mean: 3.2 mm) and overjet from - 7 to 19 mm (mean: 3.1 mm). Both an increase and a decrease in overjet, in relation to the reference category, resulted in more esthetic-related oral health-related quality of life impairments. However, in this model, only the effect for increased overjet was statistically significant (4-5 mm: + 0.4 OHIP points; ≥ 6 mm: + 0.9 OHIP points). In the regression analysis with fractional polynomials, both an increase and a decrease in overjet resulted in more esthetic impairments, characterized by a U-shaped relationship. No association could be verified for overbite. A substantial increase or decrease of overjet from the reference values is associated with esthetic impairments of oral health-related quality of life, whereas the extent of overbite seems to have no impact on esthetics.

Socioeconomic factors and mortality in urban settings: the case of Barcelona, Spain.

1995-01-01

STUDY OBJECTIVE--This study aimed to describe the relationship between health and socioeconomic indicators in the 38 neighbourhoods of the city of Barcelona, Spain. DESIGN--Mortality data for 1983-89 and socioeconomic data for each of the 38 neighbourhoods of Barcelona were used. Mortality indicators used were the comparative mortality figure, the ratio of potential years of life lost, and life expectancy at birth. Socioeconomic indicators were the percentage of unemployed, the percentage of illiteracy, monthly telephone usage, the average power and age of cars, and the average rateable value of buildings and of land. The statistical correlation between socioeconomic indicators and mortality indicators was studied by Spearman's rank correlation coefficient. SETTING--The 38 neighbourhoods of Barcelona, Spain. MEASUREMENTS AND MAIN RESULTS--The comparative mortality figure ranged from 87.41-152.43 and the ratio of potential years of life lost from 74.94-237.31 in both sexes. Both the absolute difference and the ratio of the value for the neighbourhood with lowest mortality and that with highest mortality were larger when premature mortality was examined. Life expectancy at birth ranged from 64.77-75.32 years in men and 75.04-81.51 in women. All correlations between mortality and socioeconomic indicators were high and statistically significant: the higher the unemployment and illiteracy levels and the older the cars, the greater the comparative mortality figure and ratio of potential years of life lost, and the lower the life expectancy (negative correlations). Conversely, the higher the telephone use, the more powerful the cars, and the greater the rateable value, the lower the mortality (negative correlations) and the greater the life expectancy. These correlations were greater in males than in females. The highest correlations were with illiteracy. CONCLUSIONS--This study has detected significant differences in mortality in a large town in the Mediterranean region of Europe. Images PMID:7499987

Can the NICE "end-of-life premium" be given a coherent ethical justification?

PubMed

Cookson, Richard

2013-12-01

In 2009 the UK National Institute for Health and Clinical Excellence (NICE) announced that its health technology appraisal committees would henceforth give special additional weight to health gains from life-extending end-of-life treatments. This was a response to mounting concern from NICE's stakeholders that effective new drugs for end-stage cancer often fail NICE's standard test of cost effectiveness. This change of policy may be justifiable on procedural grounds as the result of a democratic political process responding to stakeholder concerns. However, according to the "accountability for reasonableness" framework proposed by the philosopher Norman Daniels and endorsed by NICE, there also needs to be transparency about the substantive ethical grounds for public health care resource allocation decisions. In that spirit, I analyze eleven potentially relevant justifications for the NICE "end-of-life premium," drawn from the economics and philosophy literature: (1) rule of rescue, (2) fair chances, (3) ex post willingness to pay, (4) caring externality, (5) financial protection, (6) symbolic value, (7) diminishing marginal value of future life years, (8) concentration of benefits, (9) dread, (10) time to set your affairs in order, and (11) severity of illness. I conclude that none of them yields a coherent ethical justification for the NICE end-of-life premium.

Psychosomatic medicine and the philosophy of life.

Schwartz, Michael A; Wiggins, Osborne P

2010-01-21

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.

In the face of severe resource constraints, health care systems are seeking both to control costs and to ensure maximum benefits for the resources consumed. The use of Quality Adjusted Life Years (QALYs) is becoming more widely advocated as a decision aid in the solution of resource allocation problems. The QALY combines two dimensions of health outcome--the quantity of life and its quality--in such a way that choices between different services with different purposes can be made using comparisons based on common units of measurement. The combination of these two dimensions allows comparisons between services with different objectives, such as curing and caring services. The QALY, however, lacks a third dimension which is vital to the decision-making process to which it is intended to contribute: the worth of a specific life relative to others. This paper presents results based on interviews of 719 residents of Cardiff drawn at random from the electoral register. The results suggest that further development of the novel methodology used to establish the relative value placed on various human lives is worthwhile. Evidence is given which indicates that the public consider lives to be of unequal worth. The results also show that these values are consistent for different types of choices phrased in different ways on a large number of control variables, implying the existence of a cultural stable value system which is a necessary prerequisite if consensus values of human life are to be used to assist decision-making in non-private health care systems.(ABSTRACT TRUNCATED AT 250 WORDS)

Objective— To understand high-performing frontline employees’ values as reflected in their narratives of day-to-day interactions in a large health care organization. Methods— A total of 150 employees representing various roles within the organization were interviewed and asked to share work-life narratives (WLNs) about value-affirming situations (i.e. situations in which they believed their actions to be fully aligned with their values) and value-challenging situations (i.e. when their actions or the actions of others were not consistent with their values), using methods based on appreciative inquiry. Results— The analysis revealed 10 broad values. Most of the value-affirming WLNs were about the story-teller and team providing care for the patient/family. Half of the value-challenging WLNs were about the story-teller or a patient and barriers created by the organization, supervisor, or physician. Almost half of these focused on “treating others with disrespect/respect”. Only 15% of the value-challenging WLNs contained a resolution reached by the participants, often leaving them describing unresolved and frequently negative feelings. Conclusions— Appreciative inquiry and thematic analysis methods were found to be an effective tool for understanding the important and sometimes competing role personal and institutional values play in day-to-day work. There is remarkable potential in using WLNs as a way to surface and reinforce shared values and, perhaps more importantly, respectfully to identify and discuss conflicting personal and professional values.

Alaska Native (AN) college students experience higher attrition rates than their non-Native peers. Understanding the factors that contribute to quality of life ("what makes life good") for AN students will help inform supportive programs that are congruent with their culture and college life experiences. Co-develop a conceptual model and a measure of quality of life (QOL) that reflects the experiences of AN college students. Six focus groups were conducted with 26 AN college students. Within a community-academic partnership, interactive data collection activities, co-analysis workgroup sessions and an interactive findings forum ensured a participant-driven research process. Students identified and operationally defined eight QOL domains (values, culture and traditions, spirituality, relationships, basic needs, health, learning and leisure). The metaphor of a tree visually illustrates how the domains values, culture and traditions and spirituality form the roots to the other domains that appear to branch out as students navigate the dual worldviews of Native and Western ways of living. The eight QOL domains and their items identified during focus groups were integrated into a visual model and an objective QOL measure. The hope is to provide a useful tool for developing and evaluating university-based programs and services aimed toward promoting a positive QOL and academic success for AN students.

A scheme of relationships among life-history characters is developed on assumptions of determinate growth and dependence of juvenile mortality on the specific growth rate. It is shown that constraints on the relative neonate size, (W0/W infinity), and minimum value of the biotic potential, (rmax), lead to "triangular" shape of life history set on the plain defined by juvenile and adult mortality. This completely coincides with the Ramenskiĭ++--Grime (C-S-R) classification of life-history strategies. Phylogenetic constraints can reduce this set to a relatively narŕow r/K-continuum specifically oriented for a certain taxon. Similar restrictions generate models of life history optimization which predict interspecific allometries between life-history traits.

A high-precision half-life measurement for the superallowed β+ emitter Alm26 was performed at the TRIUMF-ISAC radioactive ion beam facility yielding T1/2=6346.54±0.46stat±0.60systms, consistent with, but 2.5 times more precise than, the previous world average. The Alm26 half-life and ft value, 3037.53(61) s, are now the most precisely determined for any superallowed β decay. Combined with recent theoretical corrections for isospin-symmetry-breaking and radiative effects, the corrected Ft value for Alm26, 3073.0(12) s, sets a new benchmark for the high-precision superallowed Fermi β-decay studies used to test the conserved vector current hypothesis and determine the Vud element of the Cabibbo-Kobayashi-Maskawa quark mixing matrix.

As medical technology continues increasing the possibility of living a longer life, the public's valuing of these developments must be considered. This study examines attitudes toward extending the human life span within a student population at a Christian university. Religious factors were hypothesized to affect life extension desirability. Scores on measures of willingness to defer to God's will, meaning derived from religion, positive afterlife beliefs, and intrinsic religiosity were significantly and inversely related to life extension desirability. Implications of these findings are discussed, including encouraging medical practitioners to respect decision-making processes of religious persons who may find life extension interventions undesirable.

Using a survey to estimate health expectancy and quality-adjusted life expectancy to assess inequalities in health and quality of life.

There has been a policy debate in the United Kingdom about moving beyond traditional measures of life expectancy and economic output to developing more meaningful ways of measuring national well-being. To test whether quality adjusted life expectancy (QALE) was a useful indicator of health inequalities. EuroQol five-dimensional questionnaire data from a well-being survey was combined with actuarial life expectancy (LE) data to estimate healthy LE (HLE), that is, years of life lived in good health, and QALE, that is, quality-adjusted life-years (QALYs) lived for Wirral, a borough in the north west of England. The gap between Wirral and the most deprived areas was 4.45 years for LE, 5.34 for QALE, and 7.55 for HLE. The gap in QALE was 20% greater than the gap in LE, while the gap in HLE was 70% greater. The fact that the QALE gap value lies between the HLE value and the LE value suggests that QALE is a more sensitive indicator than HLE, as in this study QALE is derived from 243 possible EuroQol five-dimensional questionnaire profiles whereas HLE is based only on whether or not an individual rates his or her health as good, a binary variable. This study discusses how QALE could be a useful indicator for measuring health inequalities in future, especially as cost utility and QALYs are seen as the gold standard used by the National Institute for Health and Clinical Excellence in the United Kingdom to measure outcomes for health interventions in England, and discusses how a monetary valuation of QALYs could be used to put a societal cost on health inequalities.

Project Lifespan-based Nonstationary Hydrologic Design Methods for Changing Environment

NASA Astrophysics Data System (ADS)

Xiong, L.

2017-12-01

Under changing environment, we must associate design floods with the design life period of projects to ensure the hydrologic design is really relevant to the operation of the hydrologic projects, because the design value for a given exceedance probability over the project life period would be significantly different from that over other time periods of the same length due to the nonstationarity of probability distributions. Several hydrologic design methods that take the design life period of projects into account have been proposed in recent years, i.e. the expected number of exceedances (ENE), design life level (DLL), equivalent reliability (ER), and average design life level (ADLL). Among the four methods to be compared, both the ENE and ER methods are return period-based methods, while DLL and ADLL are risk/reliability- based methods which estimate design values for given probability values of risk or reliability. However, the four methods can be unified together under a general framework through a relationship transforming the so-called representative reliability (RRE) into the return period, i.e. m=1/1(1-RRE), in which we compute the return period m using the representative reliability RRE.The results of nonstationary design quantiles and associated confidence intervals calculated by ENE, ER and ADLL were very similar, since ENE or ER was a special case or had a similar expression form with respect to ADLL. In particular, the design quantiles calculated by ENE and ADLL were the same when return period was equal to the length of the design life. In addition, DLL can yield similar design values if the relationship between DLL and ER/ADLL return periods is considered. Furthermore, ENE, ER and ADLL had good adaptability to either an increasing or decreasing situation, yielding not too large or too small design quantiles. This is important for applications of nonstationary hydrologic design methods in actual practice because of the concern of choosing the emerging nonstationary methods versus the traditional stationary methods. There is still a long way to go for the conceptual transition from stationarity to nonstationarity in hydrologic design.

Jewish views on abortion.

PubMed

Jakobovits, I

1968-01-01

In Jewish law right and wrong, good and evil, are absolute values which transcend time, place, and environment. They defy definition by human intuition or expediency. Jewish law derives from the Divine revelation at Mount Sinai as expounded by sages faithful to, and authorized by, its writ. The Talmud rules that if a woman is in hard travail, and her life must be saved, the child must be aborted and extracted. The mother's life comes first. The fetus is not a human life until it is born. But 19th century Rabbinical works state that it is immoral to destroy a monster child. Modern rabbis are unanimous in condemning abortion, feticide, or infanticide as an unconscionable attack on human life. However, Jewish law allows abortion if the pregnancy will cause severe psychological damage to the mother. No civilized society could survive without laws which occasionally cause some suffering or personal anguish. One human life is worth a million lives, because each life is infinite in value. In cases of rape or incest Jewish law still does not sanction abortion. Man's procreative responsibilities are serious and carry rights and obligations which would be upset by liberalized abortion laws. If a person kills a person who is mortally wounded, the killer is guilty of a moral offense.

Many publicly-funded health systems apply cost-benefit frameworks in response to the moral dilemma of how best to allocate scarce healthcare resources. However, implementation of recommendations based on costs and benefit calculations and subsequent challenges have led to 'special cases' with certain types of health benefits considered more valuable than others. Recent debate and research has focused on the relative value of life extensions for people with terminal illnesses. This research investigates societal perspectives in relation to this issue, in the UK. Q methodology was used to elicit societal perspectives from a purposively selected sample of data-rich respondents. Participants ranked 49 statements of opinion (developed for this study), onto a grid, according to level of agreement. These 'Q sorts' were followed by brief interviews. Factor analysis was used to identify shared points of view (patterns of similarity between individuals' Q sorts). Analysis produced a three factor solution. These rich, shared accounts can be broadly summarised as: i) 'A population perspective - value for money, no special cases', ii) 'Life is precious - valuing life-extension and patient choice', iii) 'Valuing wider benefits and opportunity cost - the quality of life and death'. From the factor descriptions it is clear that the main philosophical positions that have long dominated debates on the just allocation of resources have a basis in public opinion. The existence of certain moral positions in the views of society does not ethically imply, and pragmatically cannot mean, that all are translated into policy. Our findings highlight normative tensions and the importance of critically engaging with these normative issues (in addition to the current focus on a procedural justice approach to health policy). Future research should focus on i) the extent to which these perspectives are supported in society, ii) how respondents' perspectives relate to specific resource allocation questions, and iii) the characteristics of respondents associated with each perspective.

Analysis of the Seismic Performance of Isolated Buildings according to Life-Cycle Cost

PubMed Central

Dang, Yu; Han, Jian-ping; Li, Yong-tao

2015-01-01

This paper proposes an indicator of seismic performance based on life-cycle cost of a building. It is expressed as a ratio of lifetime damage loss to life-cycle cost and determines the seismic performance of isolated buildings. Major factors are considered, including uncertainty in hazard demand and structural capacity, initial costs, and expected loss during earthquakes. Thus, a high indicator value indicates poor building seismic performance. Moreover, random vibration analysis is conducted to measure structural reliability and evaluate the expected loss and life-cycle cost of isolated buildings. The expected loss of an actual, seven-story isolated hospital building is only 37% of that of a fixed-base building. Furthermore, the indicator of the structural seismic performance of the isolated building is much lower in value than that of the structural seismic performance of the fixed-base building. Therefore, isolated buildings are safer and less risky than fixed-base buildings. The indicator based on life-cycle cost assists owners and engineers in making investment decisions in consideration of structural design, construction, and expected loss. It also helps optimize the balance between building reliability and building investment. PMID:25653677

External causes of death are the third most common causes of death, after cardiovascular diseases and malignant neoplasms, in inhabitants of Poland. External causes of death pose the greatest threat to people aged 5-44, which results in a great number of years of life lost. The aim of the study is the analysis of years of life lost due to external causes of death among rural inhabitants in Poland, particularly due to traffic accidents and suicides. The study material included a database created on the basis of 2,100,785 certificates of rural inhabitants in Poland in the period 1999-2012. The SEYLL p (Standard Expected Years of Life Lost per living person) and the SEYLL d (per death) indices were used to determine years of life lost due to external causes of death. Joinpoint models were used to analyze time trends. In the period 1999-2012, 151,037 rural inhabitants died due to external causes, including 27.2% due to traffic accidents and 25.2% due to suicides. In 2012, the SEYLL p was 1,817 per 100,000 males and 298 per 100,000 females. Among males, suicides (SEYLL p = 633 years per 100,000) and traffic accidents (SEYLL p = 473 years per 100,000) contributed to the largest number of years of life lost. Among females, SEYLLp values were: 109 years due to traffic accidents and 69 years due to suicides (per 100,000). Among males, SEYLL p values started to decrease in 2008 at the average annual rate of 3.2%. In the group of females in the period 1999-2012, SEYLL p values were decreasing by 2.4% per year. The decreasing trend of the number of lost years of life due to external causes among rural inhabitants does not apply to suicides among men. The SEYLL p due to this group of causes has been steadily increasing since 1999. Analysis of the years of life lost focuses on the social and economic aspects of premature mortality due to external causes.

In order to evaluate the impact of tooth loss in patient's quality of life, 50 volunteers were selected among patients who use the Public Health Services in treatment for their complete denture's placement or replacement. The Oral Health Impact Profile (OHIP-14) and a socio-demographic data collection were applied before treatment. The values were founded through the weight of each question in association with Likert's Scale. As higher was the score, higher was the impact in the quality of life. In this survey 82% were female, 52% of patients between 41 and 60 years old (average: 59.1), and 34% married. The higher values of OHIP-14 dimensions in patient's quality of life were: Psychological Discomfort (122), Physical Pain (121), Psychological Disability (113), Physical Disability (109), Functional Limitation (93), Handicap (82) and Social Disability (76). As it could be observed, the lost of teeth or the use of inadequate prosthesis could bring negative impacts in life's quality, especially regarding preoccupation, stress with mouth problems and shame, although people perceive minor impacts in social relationships and development of their daily activities. This information can be relevant to prepare dentists to raise their knowledge about edentulous people and how to work with them.

Environmental evaluation of high-value agricultural produce with diverse water sources: case study from Southern California

Bell, Eric M.; Stokes-Draut, Jennifer R.; Horvath, Arpad

Meeting agricultural demand in the face of a changing climate will be one of the major challenges of the 21st century. California is the single largest agricultural producer in the United States but is prone to extreme hydrologic events, including multi-year droughts. Ventura County is one of California’s most productive growing regions but faces water shortages and deteriorating water quality. The future of California’s agriculture is dependent on our ability to identify and implement alternative irrigation water sources and technologies. Two such alternative water sources are recycled and desalinated water. The proximity of high-value crops in Ventura County to both dense population centers and the Pacific Ocean makes it a prime candidate for alternative water sources. This study uses highly localized spatial and temporal data to assess life-cycle energy use, life-cycle greenhouse gas emissions, operational costs, applied water demand, and on-farm labor requirements for four high-value crops. A complete switch from conventional irrigation with groundwater and surface water to recycled water would increase the life-cycle greenhouse gas emissions associated with strawberry, lemon, celery, and avocado production by approximately 14%, 7%, 59%, and 9%, respectively. Switching from groundwater and surface water to desalinated water would increase life-cycle greenhouse gas emissions by 33%, 210%, 140%, and 270%, respectively. The use of recycled or desalinated water for irrigation is most financially tenable for strawberries due to their relatively high value and close proximity to water treatment facilities. However, changing strawberry packaging has a greater potential impact on life-cycle energy use and greenhouse gas emissions than switching the water source. While this analysis does not consider the impact of water quality on crop yields, previous studies suggest that switching to recycled water could result in significant yield increases due to its lower salinity.

Toxicity of copper to early-life stage Kootenai River white sturgeon, Columbia River white sturgeon, and rainbow trout

USGS Publications Warehouse

Little, E.E.; Calfee, R.D.; Linder, G.

2012-01-01

White sturgeon (Acipenser transmontanus) populations throughout western North America are in decline, likely as a result of overharvest, operation of dams, and agricultural and mineral extraction activities in their watersheds. Recruitment failure may reflect the loss of early-life stage fish in spawning areas of the upper Columbia River, which are contaminated with metals from effluents associated with mineral-extraction activities. Early-life stage white sturgeon (A. transmontanus) from the Columbia River and Kootenai River populations were exposed to copper during 96-h flow-through toxicity tests to determine their sensitivity to the metal. Similar tests were conducted with rainbow trout (RBT [Oncorhynchus mykiss]) to assess the comparative sensitivity of this species as a surrogate for white sturgeon. Exposures were conducted with a water quality pH 8.1-8.3, hardness 81-119 mg/L as CaCO2, and dissolved organic carbon 0.2-0.4 mg/L. At approximately 30 days posthatch (dph), sturgeon were highly sensitive to copper with median lethal concentration (LC50) values ranging from 4.1 to 6.8 μg/L compared with 36.5 μg/L for 30 dph RBT. White sturgeon at 123-167 dph were less sensitive to copper with LC50 values ranging from 103.7 to 268.9 μg/L. RBT trout, however, remained more sensitive to copper at 160 dph with an LC50 value of 30.9 μg/L. The results indicate that high sensitivity to copper in early-life stage white sturgeon may be a factor in recruitment failure occurring in the upper Columbia and Kootenai rivers. When site-specific water-quality criteria were estimated using the biotic ligand model (BLM), derived values were not protective of early-life stage fish, nor were estimates derived by water-hardness adjustment.

The burden of advanced COPD is high globally; however, little is known about how often end of life strategies are used by this population. To describe trends in the use of end of life care strategies by people with advanced COPD in Ontario, Canada. A population-based repeated cross-sectional study examining end of life care strategies in individuals with advanced COPD was conducted. Annual proportions of individuals who received formal palliative care, long-term oxygen therapy or opioids from 2004 to 2014 were determined. Results were age- and sex- standardized as well as stratified by age, sex, socioeconomic status, urban/rural residence and immigrant status. Measurement/Main Results: There were 151,912 persons with advanced COPD in Ontario between 2004 and 2014. Use of formal palliative care services increased 1% per year from 5.3% in 2004 to 14.3% in 2014 (p value for trend <0.001), while use of long-term oxygen therapy increased 1.1% per year from 26.4% in 2004 to 35.3% in 2013 (p value for trend <0.001). The use of opioids was relatively stable (40.0% in 2004 and 41.8% in 2014, p value for trend=0.08). Younger individuals were less likely to use formal palliative care services and long-term oxygen therapy. Males were less likely than females to receive long-term oxygen therapy and opioids. The proportion of people with advanced COPD using end of life strategies, although increasing, remains low. Efforts should focus on increasing access to such strategies as well as educating patients and providers of their benefits.

The value of parent-to-parent support has been noted in research with parents of children who have a range of special needs and chronic medical conditions, however, less is known about the benefit of such mentorship for parents caring for seriously ill and dying children. Findings from a qualitative study with mothers of seriously ill children, including those whose children had died, provided rich and detailed information about the personal and practical resources they received from other parents. Personal recommendations to parents by parents included the value of seeking out mentorship and appreciating the small things in life, while practical suggestions encompassed encouraging parents to become informed and to advocate for their children's best interests. Mothers also identified professionals with end-of-life training as instrumental agents of support.

Undesirable recent life events in the period of three months preceding primary depressive illness were studied in two Arabian Gulf countries: Qatar (235 patients) and Kuwait (164 patients). Transit population patients, who come to these countries from employment, differ from native patients in the significant predominance of work as a source of recent life events. The difference is discussed in relation to the existential committments and attitudes to work among native and transient populations. Intergenerational conflict as an undesirable recent life event is prevalent among family recent life events in native patients where rapid sociocultural changes are associated with conflict of traditional and modern value systems.

There is some evidence that posttraumatic stress disorder (PTSD) and early life adversity may influence metabolic outcomes such as obesity, diabetes, and cardiovascular disease. However, whether and how these interact is not clear. We analyzed data from a cross-sectional and longitudinal study to determine how PTSD severity influences obesity, insulin sensitivity, and key measures and biomarkers of cardiovascular risk. We then looked at how PTSD and early life adversity may interact to impact these same outcomes. PTSD severity is associated with increasing risk of obesity, diabetes, and cardiovascular disease, with higher symptoms correlating with higher values of BMI, leptin, fibrinogen, and blood pressure, and lower values of insulin sensitivity. PTSD and early life adversity have an additive effect on these metabolic outcomes. The longitudinal study confirmed findings from the cross sectional study and showed that fat mass, leptin, CRP, sICAM-1, and sTNFRII were significantly increased with higher PTSD severity during a 2.5 year follow-up period. Individuals with early life adversity and PTSD are at high risk and should be monitored carefully for obesity, insulin resistance, and cardiometabolic risk. Copyright © 2015 Elsevier B.V.

Gas diffusion liquid storage bag and method of use for storing blood

NASA Technical Reports Server (NTRS)

Bank, H.; Cleland, E. L. (Inventor)

1979-01-01

The shelf life of stored whole blood may be doubled by adding a buffer which maintains a desired pH level. However, this buffer causes the generation of CO2 which, if not removed at a controlled rate, causes the pH value of the blood to decrease, which shortens the useful life of the blood. A blood storage bag is described which permits the CO2 to be diffused out at a controlled rate into the atmosphere, thereby maintaining the desired pH value and providing a bag strong enough to permit handling.

Prolonging thermal barrier coated specimen life by thermal cycle management

Hendricks, R. C.; Mcdonald, G.; Poolos, N. P.

1981-01-01

Thermal barrier coatings applied to the heated side of engine components such as seals, combustor, and blades of a gas turbine offer a potential increase in efficiency through the use of higher gas temperatures or less cooling air or benefits arising from extended component life by reducing component metal temperatures. The considered investigation has the objective to show that while a thermal barrier coated (TBC) specimen can be brought to a fixed temperature using various fuel-air ratio (F/A) values, lower calculated stresses are associated with lower (F/A) values. This implies that control of (F/A) values (i.e., rates of heat input) during the starting transient and to a lesser extent during shutdown and operation, offers a potential method of improving TBC lifetime through thermal cycle management.

A field biochemical epidemiology study was conducted using the Michigan cohort consisting of 51 rural residents exposed to polybrominated biphenyls (PBB). The study had three major objectives: (a) to determine the serum half-life of the major PBB congener, hexabromobiphenyl (HBB), in the human, (b) to determine if the PBB-exposed subjects had elevated cytochrome P-450I function as determined by the caffeine breath test (CBT) and the caffeine urinary metabolite ratio (CMR), and (c) to determine the applicability of the CBT and CMR in field studies. PBB serum levels were detected in 36 of the 51 PBB-exposed subjects. The serum half-life ofmore » HBB was determined by comparing the current serum HBB values to the subject's previous serum values obtained 5 to 8 years earlier. The median HBB half-life was 12 years (range 4-97 years). The CBT and CMR were elevated in the subjects exposed to PBBs as compared to the values obtained from urban nonsmokers and were similar to those found in adults who smoke. A gender effect was seen in the PBB-exposed subjects. There was a correlation between the CBT and the HBB serum values but not between CMR and HBB serum values. The CBT and CMR were easily conducted in the field and appear to be useful metabolic probes of cytochrome P-450I activity in human environmental toxicology.« less

The effect of individual differences and manipulated life expectancies on the willingness to engage in sexual coercion.

PubMed

Dunkel, Curtis S; Mathes, Eugene

2011-12-16

The role of the individual difference variables of mate value, short-term and long-term mating preferences, and life history strategy along with the manipulated variable of life expectancy were used to predict differences in the willingness to engage in sexually coercive behaviors. Short-term preferences and long-term preferences were correlated with the willingness to engage in sexual coercion at all life expectancies. Life history strategy was correlated with the willingness to engage in sexual coercion at only the shortest and longest life expectancies. Most importantly short-term and long-term mating preferences interacted with life expectancy to predict the willingness to engage in sexually coercive behaviors. Short life expectancies increased willingness in individuals with high short-term and low long-term preferences. The results are discussed in terms of the varying theories of sexual coercion with emphasis put on a life history approach.

Over the years many different psychologists and psychoanalysts have found value in the concept of the self-narrative, or the "life story." Narrative thought demands an appreciation of the particulars of time and place and a focus on multidimensional understanding of events, people, emotion, and motivation. By using the life story or…

From maturity to value-added innovation: lessons from the pharmaceutical and agro-biotechnology industries.

PubMed

Mittra, James; Tait, Joyce; Wield, David

2011-03-01

The pharmaceutical and agro-biotechnology industries have been confronted by dwindling product pipelines and rapid developments in life sciences, thus demanding a strategic rethink of conventional research and development. Despite offering both industries a solution to the pipeline problem, the life sciences have also brought complex regulatory challenges for firms. In this paper, we comment on the response of these industries to the life science trajectory, in the context of maturing conventional small-molecule product pipelines and routes to market. The challenges of managing transition from maturity to new high-value-added innovation models are addressed. Furthermore, we argue that regulation plays a crucial role in shaping the innovation systems of both industries, and as such, we suggest potentially useful changes to the current regulatory system.

Meaning in life is a multi-faceted construct that has been conceptualized in diverse ways. It refers broadly to the value and purpose of life, important life goals, and for some, spirituality. We developed a measure of meaning in life derived from this conceptualization and designed to be a synthesis of relevant theoretical and empirical traditions. Two samples, all cancer patients, provided data for scale development and psychometric study. From exploratory and confirmatory factor analyses the Meaning in Life Scale (MiLS) emerged, and includes four aspects: Harmony and Peace, Life Perspective, Purpose and Goals, Confusion and Lessened Meaning, and Benefits of Spirituality. Supporting data for reliability (internal consistency, test–retest) and construct validity (convergent, discriminant, individual differences) are provided. The MiLS offers a theoretically based and psychometrically sound assessment of meaning in life suitable for use with cancer patients. PMID:16838197

Kinetics of changes in shelf life parameters during storage of pearl millet based kheer mix and development of a shelf life prediction model.

PubMed

Bunkar, Durga Shankar; Jha, Alok; Mahajan, Ankur; Unnikrishnan, V S

2014-12-01

Pearl millet, dairy whitener and sugar powder were blended for preparing pearl millet kheer mix. Pearl millet based kheer mix samples were stored at 8, 25, 37 and 45 °C under nitrogen flushing environment. Changes in HMF and TBA formation in the dry mix and sensory changes in reconstituted kheer were studied upto 180 days. In fresh dry mix, the average value of HMF recorded was 4.87 μmol/g which increased to 11.23, 13.67, 18.13, and 21.43 μmol/g at 8, 25, 37 and 45 °C, respectively after 180 days of storage. From an initial value of 0.067, the TBA value increased to 0.219, 0.311, 0.432 and 0.613 at 532 nm at 8, 25, 37 and 45 °C, respectively after 180 days of storage. Data generated from the chemical kinetics of HMF and TBA development that progressed during storage of pearl millet kheer mix were modeled using Arrhenius equations to predict the shelf life of the product. Changes in HMF and TBA followed first order reaction kinetics. It was found that the potential shelf life of the pearl millet based kheer mix was 396 days at 8 and 288 days at 25 °C, respectively.

Self-efficacy has emerged as a potential predictor of quality of life for adults who stutter. Research has focused primarily on the positive relationship self-efficacy has to treatment outcomes, but little is known about the relationship between self-efficacy and quality of life for adults who stutter. The purpose of this mixed- methods study is to determine the predictive value of self-efficacy and its relationship to quality of life for adults who stutter. The Self-Efficacy Scale for Adult Stutterers and the Overall Assessment of the Speaker's Experience with Stuttering were administered to 39 adults who stutter, aged 18- 77. Percentage of syllables stuttered was calculated from a conversational speech sample as a measure of stuttered speech frequency. Qualitative interviews with semi-structured probes were conducted with 10 adults and analyzed using thematic analysis to explore the lived experience of adults who stutter. Self-efficacy emerged as a strong positive predictor of quality of life for adults living with a stuttered speech disorder. Stuttered speech frequency was a moderate negative predictor of self-efficacy. Major qualitative themes identified from the interviews with the participants were: encumbrance, self-concept, confidence, acceptance, life-long journey, treatment, and support. Results provide clarity on the predictive value of self-efficacy and its relationship to quality of life and stuttered speech frequency. Findings highlight that the unique life experiences of adults who stutter require a multidimensional approach to the assessment and treatment of stuttered speech disorders. Crown Copyright © 2017.

Well-being development at the end of life is often characterized by steep deteriorations, but individual differences in these terminal declines are substantial and not yet well understood. This study moved beyond typical consideration of health predictors and explored the role of social orientation and engagement. To do so, we used social variables at the behavioral level (self-ratings of social participation) and the motivational level (valuing social and family goals), assessed 2 to 4 years before death. We applied single- and multiphase growth models to up to 27-year annual longitudinal data from 2,910 now deceased participants of the nation-wide German Socio-Economic Panel Study (Mage at death = 74 years; SD = 14; 48% women). Results revealed that leading a socially active life and prioritizing social goals in late life were independently associated with higher late-life well-being, less pronounced late-life decline, and a later onset of terminal decline. Significant interaction effects suggested that the combination of (reduced) social participation and (lowered) social goals magnifies the effects of each other. Findings also indicated that less decline in social participation was associated with less severe rates and a later onset of well-being decline. We found little evidence that valuing family goals is associated with late-life trajectories of well-being. Associations were independent of key correlates of well-being and mortality, including age at death, gender, education, disability, hospital stays, and goals in other life domains. We discuss possible pathways by which maintaining social orientation into late life may help mitigate terminal decline in well-being. (c) 2016 APA, all rights reserved).

Ferriman, Kimberley; Lubinski, David; Benbow, Camilla P

2009-09-01

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.

Review article: Medical decision models of Helicobacter pylori therapy to prevent gastric cancer.

PubMed

Sonnenberg, A; Inadomi, J M

1998-02-01

The aim of the present article is to study the utility of Helicobacter pylori eradication programmes in decreasing the incidence of gastric cancer. Three types of decision models are employed to pursue this aim, i.e. decision tree, present value, and declining exponential approximation of life expectancy (DEALE). 1) A decision tree allows one to model the interaction of multiple variables in great detail and to calculate the marginal cost, as well as the marginal cost-benefit ratio, of a preventive strategy. The cost of gastric cancer, the efficacy of H. pylori therapy in preventing cancer, and the cumulative probability of developing gastric cancer exert the largest influence on the marginal cost of cancer prevention. The high cost of future gastric cancer and a high efficacy of therapy make screening for H. pylori and its eradication the preferred strategy. 2) The present value is an economic method to adjust future costs or benefits to their current value using a discount rate and the length of time between now and a given time point in the future. It accounts for the depreciation of money and all material values over time. During childhood, the present value of future gastric cancer is very low. Vaccination of children to prevent gastric cancer would need to be very inexpensive to be practicable. Cancer prevention becomes a feasible option, only if the time period between the preventive measures and the occurrence of gastric cancer can be made relatively short. 3) The DEALE provides a means to calculate the increase in life expectancy that would occur, if death from a particular disease became preventable. Life expectancy of the general population is hardly affected by gastric cancer. For life expectancy to increase appreciably by vaccination or antibiotic therapy directed against H. pylori infection, these interventions would need to be focused towards a sub-population with an a priori high risk for gastric cancer.

Predictors of life satisfaction among caregivers of individuals with multiple sclerosis.

Research on life satisfaction among caregivers of persons with multiple sclerosis (MS) is sparse. This study examined the extent to which MS-specific disease and psychosocial characteristics predict caregiver life satisfaction. Participants were 64 caregivers of patients with MS and the patients for whom they care. Multiple regression analysis indicated that caregiver perception of illness uncertainty and patients' unawareness of deficits have unique value in predicting caregiver life satisfaction, even after accounting for general financial status. Gender and level of social support were also important contributing factors to caregiver life satisfaction. The findings suggest that duration and severity of the patients' illness take a greater toll on life satisfaction of caregivers with low versus high social support, particularly among women caregivers.

Long-Term Effects of Tetanus Toxoid Inoculation on the Demography and Life Expectancy of the Cayo Santiago Rhesus Macaques

Tetanus was a major cause of mortality in the free-ranging population of rhesus monkeys on Cayo Santiago prior to 1985 when the entire colony was given its first dose of tetanus toxoid. The immediate reduction in mortality that followed tetanus toxoid inoculation (TTI) has been documented, but the long-term demographic effects of eliminating tetanus infections have not. This study uses the Cayo Santiago demographic database to construct comparative life tables 12 years before, and 12 years after, TTI. Life tables and matrix projection models are used to test for differences in: (i) survival among all individuals as well as among social groups, (ii) long-term fitness of the population, (iii) age distribution, (iv) reproductive value, and (v) life expectancy. A retrospective life table response experiment (LTRE) was performed to determine which life cycle transition contributed most to observed changes in long-term fitness of the population post-TTI. Elimination of clinical tetanus infections through mass inoculation improved the health and well-being of the monkeys. It also profoundly affected the population by increasing survivorship and long-term fitness, decreasing the differences in survival rates among social groups, shifting the population’s age distribution towards older individuals, and increasing reproductive value and life expectancy. These findings are significant because they demonstrate the long-term effects of eradicating a major cause of mortality at a single point in time on survival, reproduction, and overall demography of a naturalistic population of primates.

We describe a novel Internet-based method for building consensus and clarifying conflicts in large stakeholder groups facing complex issues, and we use the method to survey and map the scientific and organizational perspectives of the artificial life community during the Seventh International Conference on Artificial Life (summer 2000). The issues addressed in this survey included artificial life's main successes, main failures, main open scientific questions, and main strategies for the future, as well as the benefits and pitfalls of creating a professional society for artificial life. By illuminating the artificial life community's collective perspective on these issues, this survey illustrates the value of such methods of harnessing the collective intelligence of large stakeholder groups.

Dignity therapy is a novel therapeutic approach designed to decrease suffering, enhance quality of life and bolster a sense of dignity for patients approaching death. The benefits of dignity therapy were previously documented in a sample of 100 terminally ill patients. One of the products of dignity therapy is a transcript of the edited therapy session(s). In this qualitative study, 50 of the 100 (17 from Winnipeg, Manitoba, Canada, and 33 from Perth, Australia) dignity therapy transcripts were randomly drawn, and independently coded and analysed by three investigators using a grounded theory approach. The transcripts revealed that dignity therapy serves to provide a safe, therapeutic environment for patients to review the most meaningful aspects of their lives in such a manner that their core values become apparent. The most common values expressed by the patients included 'Family', 'Pleasure', 'Caring', 'A Sense of Accomplishment', 'True Friendship', and 'Rich Experience'. Exemplars of each of these values illustrate the pervasive, defining role of values in our lives. The findings are discussed in terms of values theory, the role of dignity therapy, and consideration of values clarification in clinicians' efforts to enhance the dignity of terminally ill patients.
