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

Peters, T.

The Savannah River National Laboratory (SRNL) prepared approximately 240 gallons of Caustic-Side Solvent Extraction (CSSX) solvent for use at the Salt Waste Processing Facility (SWPF). An Extraction, Scrub, and Strip (ESS) test was performed on a sample of the prepared solvent using a salt solution prepared by Parsons to determine cesium distribution ratios (D(Cs)), and cesium concentration in the strip effluent (SE) and decontaminated salt solution (DSS) streams. This data will be used by Parsons to help qualify the solvent for use at the SWPF. The ESS test showed acceptable performance of the solvent for extraction, scrub, and strip operations.more » The extraction D(Cs) measured 15.5, exceeding the required value of 8. This value is consistent with results from previous ESS tests using similar solvent formulations. Similarly, scrub and strip cesium distribution ratios fell within acceptable ranges.« less

Parent training (PT) is well established for reducing child externalizing problems; however, lower rates of engagement in PT among ethnic minority/immigrant families have been found. We assessed PT acceptability among Chinese immigrant parents and explored clinical and cultural factors that may be associated with acceptability. Participants were a community sample of 145 Chinese immigrant parents (84% mothers) between the ages of 32 and 65 years (M=43.3 years, SD=6.2) who had children (84 boys, 59 girls) between the ages of 4 and 17 years (M=10.7 years, SD=3.6). Results suggest that parents found positive reinforcement techniques significantly more acceptable, less problematic, and more likely to be supported by others than punishment-based techniques. Parents who endorsed the Chinese child-rearing value of shaming were less likely to find PT acceptable. Parents who reported greater dysfunction in parent-child interactions rated PT as more acceptable, and families with prior Child Protective Services (CPS) involvement rated PT as less acceptable. However, previous mental health treatment appears to bolster acceptability among parents with prior CPS involvement. Clinical implications for addressing barriers to PT engagement and future research directions are discussed. Copyright © 2011. Published by Elsevier Ltd.

Given the proximity and recent spread of rabies in Indonesia, effective rabies surveillance in dogs is a priority in Northern Australia and Papua New Guinea (PNG). Reporting of potential cases requires community engagement; therefore, the value and acceptability of such a system is critical to ensure sustainable surveillance. We used qualitative research methods to identify factors that influence the acceptability and value of community-based rabies surveillance. Thirty-two semi-structured interviews were conducted with informants in 16 communities in East Arnhem, the Northern Peninsula Area, the Torres Strait in Australia, and in Western Province, PNG. Thematic analysis identified common themes including the importance of verbal communication, particularly via radio, community meetings, and direct conversation. We also found that dogs have high value to community members through connection to culture, economic (especially hunting), and companionship. The greatest barrier to the reporting of sick dogs was insufficient veterinary services and the subsequent lack of treatment response. In some regions, acceptance that sick dogs are a normal daily occurrence and lack of trust of authorities were also barriers to reporting. The findings from this study will be used to design sustainable rabies surveillance in Northern Australia and PNG by utilizing traditional communication channels and building on existing and valued animal-management services. The methods and findings of this study complement previous quantitative research, so as to target surveillance to high-risk areas within these regions.

Sphericity determination using resonant ultrasound spectroscopy

A method is provided for grading production quantities of spherical objects, such as roller balls for bearings. A resonant ultrasound spectrum (RUS) is generated for each spherical object and a set of degenerate sphere-resonance frequencies is identified. From the degenerate sphere-resonance frequencies and known relationships between degenerate sphere-resonance frequencies and Poisson's ratio, a Poisson's ratio can be determined, along with a "best" spherical diameter, to form spherical parameters for the sphere. From the RUS, fine-structure resonant frequency spectra are identified for each degenerate sphere-resonance frequency previously selected. From each fine-structure spectrum and associated sphere parameter values an asphericity value is determined. The asphericity value can then be compared with predetermined values to provide a measure for accepting or rejecting the sphere.

This paper aims to describe 'Cognitive Existential Couple Therapy' (CECT), a novel couples-based intervention for men with early stage prostate cancer (PCa) and their partners, and to report preliminary findings from a pilot study that investigated the acceptability and feasibility of the intervention and the measures to be used in a subsequent randomised controlled trial. A manualised CECT programme was delivered to 12 couples facing a diagnosis of PCa within the previous 12 months by psychiatrists and clinical psychologists. Participants completed measures of psychological distress, marital function and coping pattern before and after CECT. Semi-structured interviews were conducted with nine couples shortly after the completion of CECT. The application of CECT was both feasible and acceptable as indicated by favourable participant compliance (10 of the 12 couples attended all six designated sessions), completion of measures before and after CECT and participation in semi-structured interviews by nine couples. Preliminary results included reduced levels of avoidance and hyperarousal after the programme, with this effect stronger in partners than in patients. Interviews demonstrated that couples valued the therapist's contribution to their overall care. Previous research suggests that a couple-focused psychological intervention is desirable in the context of early stage PCa. This pilot study has established that CECT is acceptable, feasible and valued by couples facing a recent PCa diagnosis and demonstrates a potential for reduced psychological distress following CECT. A randomised controlled trial is currently being undertaken to validate the efficacy of this novel approach. Copyright © 2011 John Wiley & Sons, Ltd.

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.

Fuzzy numbers and more generally linguistic values are approximate assessments, given by experts and accepted by decision-makers when obtaining value that is more accurate is impossible or unnecessary. Distance between two fuzzy numbers plays an important role in linguistic decision-making. It is reasonable to define a fuzzy distance between fuzzy objects. To achieve this aim, the researcher presents a new distance measure for fuzzy numbers by means of improved centroid distance method. The metric properties are also studied. The advantage is the calculation of the proposed method is far simple than previous approaches.

The National Environmental Protection Agency of Italy (APAT) performed a soil sampling intercomparison, inviting 14 regional agencies to test their own soil sampling strategies. The intercomparison was carried out at a reference site, previously characterised for metal mass fraction distribution. A wide range of sampling strategies, in terms of sampling patterns, type and number of samples collected, were used to assess the mean mass fraction values of some selected elements. The different strategies led in general to acceptable bias values (D) less than 2sigma, calculated according to ISO 13258. Sampling on arable land was relatively easy, with comparable results between different sampling strategies.

Our contribution focuses on the characterization of sleep apnea from a cardiac rate point of view, using Recurrence Quantification Analysis (RQA), based on a Heart Rate Variability (HRV) feature selection process. Three parameters are crucial in RQA: those related to the embedding process (dimension and delay) and the threshold distance. There are no overall accepted parameters for the study of HRV using RQA in sleep apnea. We focus on finding an overall acceptable combination, sweeping a range of values for each of them simultaneously. Together with the commonly used RQA measures, we include features related to recurrence times, and features originating in the complex network theory. To the best of our knowledge, no author has used them all for sleep apnea previously. The best performing feature subset is entered into a Linear Discriminant classifier. The best results in the “Apnea-ECG Physionet database” and the “HuGCDN2014 database” are, according to the area under the receiver operating characteristic curve, 0.93 (Accuracy: 86.33%) and 0.86 (Accuracy: 84.18%), respectively. Our system outperforms, using a relatively small set of features, previously existing studies in the context of sleep apnea. We conclude that working with dimensions around 7–8 and delays about 4–5, and using for the threshold distance the Fixed Amount of Nearest Neighbours (FAN) method with 5% of neighbours, yield the best results. Therefore, we would recommend these reference values for future work when applying RQA to the analysis of HRV in sleep apnea. We also conclude that, together with the commonly used vertical and diagonal RQA measures, there are newly used features that contribute valuable information for apnea minutes discrimination. Therefore, they are especially interesting for characterization purposes. Using two different databases supports that the conclusions reached are potentially generalizable, and are not limited by database variability. PMID:29621264

Nuclear DNA C‐values in 30 Species Double the Familial Representation in Pteridophytes

2002-01-01

Nuclear DNA C‐values and genome size are important biodiversity characters with fundamental biological significance. Yet C‐value data for pteridophytes, a diverse group of vascular plants with approx. 9000 extant species, remain scarce. A recent survey by Bennett and Leitch (2001, Annals of Botany 87: 335–345) found that C‐values were reported for only 48 pteridophyte species. To improve phylogenetic representation in this group and to check previously reported estimates, C‐values for 30 taxa in 17 families were measured using flow cytometry for all but one species. This technique proved generally applicable, but the ease with which C‐value data were generated varied greatly between materials. Comparing the new data with those previously published revealed several large discrepancies. After discounting doubtful data, C‐values for 62 pteridophyte species remained acceptable for analysis. The present work has increased the number of such species’ C‐values by 93 %, and more than doubled the number of families represented (from 10 to 21). Analysis shows that pteridophyte C‐values vary approx. 450‐fold, from 0·16 pg in Selaginella kraussiana to 72·7 pg in Psilotum nudum var. gasa. Superimposing C‐value data onto a robust phylogeny of pteridophytes suggests some possible trends in C‐value evolution and highlights areas for future work. PMID:12197518

Acceptability of financial incentives for health behaviour change to public health policymakers: a qualitative study.

Providing financial incentives contingent on healthy behaviours is one way to encourage healthy behaviours. However, there remains substantial concerns with the acceptability of health promoting financial incentives (HPFI). Previous research has studied acceptability of HPFI to the public, recipients and practitioners. We are not aware of any previous work that has focused particularly on the views of public health policymakers. Our aim was to explore the views of public health policymakers on whether or not HPFI are acceptable; and what, if anything, could be done to maximise acceptability of HPFI. We recruited 21 local, regional and national policymakers working in England via gatekeepers and snowballing. We conducted semi-structured in-depth interviews with participants exploring experiences of, and attitudes towards, HPFI. We analysed data using the Framework approach. Public health policymakers working in England acknowledged that HPFI could be a useful behaviour change tool, but were not overwhelmingly supportive of them. In particular, they raised concerns about effectiveness and cost-effectiveness, potential 'gaming', and whether or not HPFI address the underlying causes of unhealthy behaviours. Shopping voucher rewards, of smaller value, targeted at deprived groups were particularly acceptable to policymakers. Participants were particularly concerned about the response of other stakeholders to HPFI - including the public, potential recipients, politicians and the media. Overall, the interviews reflected three tensions. Firstly, a tension between wanting to trust individuals and promote responsibility; and distrust around the potential for 'gaming the system'. Secondly, a tension between participants' own views about HPFI; and their concerns about the possible views of other stakeholders. Thirdly, a tension between participants' personal distaste of HPFI; and their professional view that they could be a valuable behaviour change tool. There are aspects of design that influence acceptability of financial incentive interventions to public health policymakers. However, it is not clear that even interventions designed to maximise acceptability would be acceptable enough to be recommended for implementation. Further work may be required to help policymakers understand the potential responses of other stakeholder groups to financial incentive interventions.

Picture archiving and communication system (PACS) has allowed the medical images to be transmitted, stored, retrieved, and displayed in different locations of a hospital or health system. Using PACS in the emergency department will eventually result in improved efficiency and patient care. In spite of the abundant benefits of employing PACS, there are some challenges in implementing this technology like users' resistance to accept the technology, which has a critical role in PACS success. In this study, we will assess and compare user acceptance of PACS in the emergency departments of three different hospitals and investigate the effect of socio-demographic factors on this acceptance. A variant of technology acceptance model (TAM) has been used in order to measure the acceptance level of PACS in the emergency department of three educational hospitals in Iran. A previously used questionnaire was validated and utilized to collect the study data. A stepwise multiple regression model was used to predict factors influencing acceptance score as the dependent variable. Mean age of participants was 32.9 years (standard deviation [SD] = 6.08). Participants with the specialty degree got a higher acceptance score than the three other groups (Mean ± SD = 4.17 ± 0.20). Age, gender, degree of PACS usage and participant's occupation (profession) did not influence the acceptance score. In our multiple regression model, all three variables of perceived usefulness (PU), perceived ease of use (PEU) and the effect of PACS (change) had a significant effect in the prediction of acceptance. The most influencing factor was change with the beta of 0.22 (P value < 0.001). PACS is highly accepted in all three emergency departments especially among specialists. PU, PEU and change are factors influencing PACS acceptance. Our study can be used as an evidence of PACS acceptance in emergency wards.

Bisphenol A and Risk Management Ethics

Resnik, David B.; Elliot, Kevin C.

2013-01-01

It is widely recognized that endocrine disrupting compounds, such as Bisphenol A, pose challenges for traditional paradigms in toxicology, insofar as these substances appear to have a wider range of low-dose effects than previously recognized. These compounds also pose challenges for ethics and policymaking. When a chemical does not have significant low-dose effects, regulators can allow it to be introduced into commerce or the environment, provided that procedures and rules are in place to keep exposures below an acceptable level. This option allows society to maximize the benefits from the use of the chemical while minimizing risks to human health or the environment, and it represents a compromise between competing values. When it is not possible to establish acceptable exposure levels for chemicals that pose significant health or environmental risks, the most reasonable options for risk management may be to enact either partial or complete bans on their use. These options create greater moral conflict than other risk management strategies, leaving policymakers difficult choices between competing values. PMID:24471646

Several parameters (sodium chloride, moisture, intramuscular fat, total nitrogen, non-protein nitrogen, white precipitates, free tyrosine, L* a* b* values and acceptability) related with proteolysis during the curing were compared in dry-cured hams manufactured from refrigerated and frozen/thawed raw material. Pre-cure freezing increased the proteolysis levels significantly (p<0.05) in the zones of the ham where water losses and absorption of salt is slowest. Frozen hams present a high incidence of white precipitates, formed mainly by tyrosine crystals. The colour and acceptability scores are similar in frozen and refrigerated hams. The previous freezing and thawing process accentuates the water losses, salt absorption and proteolysis of the cured meat, although it does not significantly affect the sensory quality of the dry-cured ham.

Charge-changing and fragment production cross sections at 0circ have been obtained for interactions of 290 MeV/nucleon and 400MeV/nucleon carbon beams with C, CH2, Al, Cu, Sn, and Pb targets. Thesebeams are relevant to cancer therapy, space radiation, and the productionof radioactive beams. We compare to previously published results using Cand CH2 targets at similar beam energies. Due to ambiguities arising fromthe presence of multiple fragments on many events, previous publicationshave reported only cross sections for B and Be fragments. In this work wehave extracted cross sections for all fragment species, using dataobtained at three distinct values of angular acceptance, supplementedmore » bydata taken with the detector stack placed off the beam axis. A simulationof the experiment with the PHITS Monte Carlo code shows fair agreementwith the data obtained with the large acceptance detectors, but agreementis poor at small acceptance.

Though PHITS and NUCFRG2 reproduce thecharge-changing cross sections with reasonable accuracy, none of themodels is able to accurately predict the fragment cross sections for allfragment species and target materials.« less

Self-efficacy and pain acceptance as mediators of the relationship between pain and performance of valued life activities in women and men with rheumatoid arthritis.

To study whether personal factors (self-efficacy and pain acceptance) mediate the relationship between pain and performance of valued life activities in persons with rheumatoid arthritis. Persons with rheumatoid arthritis for at least four years ( n = 737; 73% women) answered a questionnaire measuring self-efficacy, pain acceptance, performance of valued life activities, and self-rated pain. Relationships among these constructs were explored using univariate and multivariate analyses. Structural equation modelling was then used to examine the mediational role of personal factors on the relationship between pain and performance of valued life activities. A direct negative association between pain and performance of valued life activities was identified ( Beta = .34, P < .001). This suggests that people with rheumatoid arthritis who had higher levels of pain has increased difficulties in performing valued life activities. Self-efficacy and activity engagement component of pain acceptance mediated the relationship between pain and performance of valued life activities, however the pain willingness component of pain acceptance did not influence participation in valued life activities. These findings highlight the importance of considering personal factors, such as pain acceptance and self-efficacy, in facilitating participation in valued life activities.

Since 1997, linac based stereotactic radiotherapy (SRT) of uveal melanoma has been continuously developed at the Department of Radiotherapy, Medical University Vienna. The aim of the present study was (i) to test a new type of radiochromic film (Gafchromic EBT) for dosimetric verification of class solutions for these treatments and (ii) to verify treatment plan acceptance criteria, which are based on gamma values statisitcs. An EPSON Expression 1680 Pro flat bed scanner was utilized for film reading. To establish a calibration curve, films were cut in squares of 2 x 2 cm2, positioned at 5 cm depth in a solid water phantom and were irradiated with different dose levels (0.5 and 5 Gy) in a 5 x 5 cm2 field at 6 MV. A previously developed solid phantom (polystyrene) was used with overall dimensions corresponding to an average human head. EBT films were placed at four different depths (10, 20, 25 and 30 mm) and all films were irradiated simultaneously. Four different treatment plans were verified that resemble typical clinical situations. These plans differed in irradiation technique (conformal mMLC or circular arc SRT) and in tumour size (PTV of 1 or 2.5 cm3). In-house developed software was applied to calculate gamma (gamma) index values and to perform several statistical operations (e.g. gamma-area histograms). At depths of 10 mm gamma1%, (gamma-value where 1% of the points have an equal or higher value in the region of interest) were between 1-3 and maximum gamma > 1 (% of gamma-values > 1 in the region of interest) areas were almost 30%. At larger depths, i.e. more close to the isocenter, gamma 1% was < 1 and gamma > 1 areas were mostly < 5%. Average gamma values were about 0.5. Besides the compromised accuracy in the buildup region, previously defined IMRT acceptance criteria [Stock et al., Phys. Med Biol. 50 (2005) 399-411] could be applied as well to SRT. Radiochromic EBT films, in combination with a flat-bed scanner, were found to be an ideal multidimensional dosimetric tool for treatment plan quality assurance. EBT films are a suitable and reliable dosimetric tool that could replace traditionally used radiographic films. The presented acceptance criteria for SRT treatment plans might be used as a benchmarking data-set for other stereotactic applications and/or other equipment (planning system and delivery hardware) combinations.

The aim of the present study was to determine the characteristics of an analytical method for determination of free sulphydryl (SH) groups of wheat gluten performed with previous gluten incubation for variable times (45, 90 and 135min) at variable temperatures (30 and 37°C), in order to determine its fitness-for-purpose. It was observed that the increase in temperature and gluten incubation time caused the increase in the amount of free SH groups, with more dynamic changes at 37°C. The method characteristics identified as relevant were: linearity, limit of detection, limit of quantification, precision (repeatability and reproducibility) and measurement uncertainty, which were checked within the validation protocol, while the method performance was monitored by X- and R-control charts. Identified method characteristics demonstrated its acceptable fitness-for-purpose, when assay included previous gluten incubation at 30°C. Although the method repeatability at 37°C was acceptable, the corresponding reproducibility did not meet the performance criterion on the basis of HORRAT value (HORRAT<2).

This study investigated whether this relationship is also found in patients with ABI. We also explored the impact of the perceived ability to live according to one's own values (life-values-match). A total of 68 individuals (18-65 years of age) with an acquired brain injury completed a battery of questionnaires. The relations between health-related QOL (SF-36) and disease specific QOL (EBIQ; European Brain Injury Questionnaire), and personal values (Schwartz Values Inventory) and acceptance (ICQ; Illness Cognitions Questionnaire) were investigated. An additional question measured the life-values-match. Rehabilitation professionals reported the extent of impairment involved. Acceptance was positively associated with mental aspects of health-related QOL and the EBIQ Core Scale, after demographic variables and the extent of impairment were introduced in the regression. In a post hoc analysis we found that the life-values-match mediated the relationship between acceptance and mental aspects of QOL. In patients with an ABI, promoting acceptance may be useful to protect QOL. Strengthening the life-values-match may be a way to accomplish this.

Self-administration of a multimedia health literacy measure in clinic settings is a novel concept. Demonstrated ease of use and acceptability will help predicate the future value of this strategy. We previously demonstrated the acceptability of a “Talking Touchscreen” for health status assessment. For this study, we adapted the touchscreen for self-administration of a new health literacy measure. Primary care patients (n=610) in clinics for underserved populations completed health status and health literacy questions on the Talking Touchscreen and participated in an interview. Participants were 51% female, 10% age 60+, 67% African American, 18% without a high school education, and 14% who had never used a computer. The majority (93%) had no difficulty using the touchscreen, including those who were computer-naïve (87%). Most rated the screen design as very good or excellent (72%), including computer-naïve patients (71%) and older patients (75%). Acceptability of the touchscreen did not differ by health literacy level. The Talking Touchscreen was easy to use and acceptable for self-administration of a new health literacy measure. Self-administration should reduce staff burden and costs, interview bias, and feelings of embarrassment by those with lower literacy. Tools like the Talking Touchscreen may increase exposure of underserved populations to new technologies. PMID:20845195

Negotiating Commercial Interests in Biospecimens.

Roberts, Jessica L

2017-03-01

Proposed changes to the Common Rule would require publicly funded researchers to disclose whether a subject's biospecimens could be used for commercial profit and whether the subject will share in those proceeds. Disclosing commercial interests will inform research participants that their tissue may have commercial value, a possibility that those individuals might not have previously considered. The proposed changes may then provide people with an opportunity to negotiate commercial rights in their biospecimens despite the well-accepted legal precedent that individuals maintain no interests in their excised tissue.

Kerosene-lampblack mixtures with addition of a ground colored chalk were used in an experiment on visualizing surface flows of swept shock boundary-layer interactions. The results show that contrasting colors intensify the visualization of different regions of the interaction surface, and help the eye in following the fine streaks to locate the upstream influence. The study confirms observations of the separation occurring at shock strength below accepted values. The superiority of the reported technique over the previous monochrome technique is demonstrated.

Background Picture archiving and communication system (PACS) has allowed the medical images to be transmitted, stored, retrieved, and displayed in different locations of a hospital or health system. Using PACS in the emergency department will eventually result in improved efficiency and patient care. In spite of the abundant benefits of employing PACS, there are some challenges in implementing this technology like users’ resistance to accept the technology, which has a critical role in PACS success. Objectives In this study, we will assess and compare user acceptance of PACS in the emergency departments of three different hospitals and investigate the effect of socio-demographic factors on this acceptance. Materials and Methods A variant of technology acceptance model (TAM) has been used in order to measure the acceptance level of PACS in the emergency department of three educational hospitals in Iran. A previously used questionnaire was validated and utilized to collect the study data. A stepwise multiple regression model was used to predict factors influencing acceptance score as the dependent variable. Results Mean age of participants was 32.9 years (standard deviation [SD] = 6.08). Participants with the specialty degree got a higher acceptance score than the three other groups (Mean ± SD = 4.17 ± 0.20). Age, gender, degree of PACS usage and participant’s occupation (profession) did not influence the acceptance score. In our multiple regression model, all three variables of perceived usefulness (PU), perceived ease of use (PEU) and the effect of PACS (change) had a significant effect in the prediction of acceptance. The most influencing factor was change with the beta of 0.22 (P value < 0.001). Conclusion PACS is highly accepted in all three emergency departments especially among specialists. PU, PEU and change are factors influencing PACS acceptance. Our study can be used as an evidence of PACS acceptance in emergency wards. PMID:27679692

Familism Values, Family Time, and Mexican-Origin Young Adults’ Depressive Symptoms

PubMed Central

Zeiders, Katharine H.; Updegraff, Kimberly A.; Umaña-Taylor, Adriana J.; McHale, Susan M.; Padilla, Jenny

2015-01-01

Using longitudinal data across eight years, this study examined how parents’ familism values in early adolescence predicted youths’ depressive symptoms in young adulthood via youths’ familism values and family time. We examined these processes among 246 Mexican-origin families using interview and phone-diary data. Findings revealed that fathers’ familism values predicted male and female youths’ familism values in middle adolescence. For female youth only, fathers’ familism values also predicted youths’ family time in late adolescence. The link between family time and young adults’ depressive symptoms depended on parental acceptance and adolescent gender: Among female and male youth, family time predicted fewer depressive symptoms, but only when paternal acceptance was high. For female adolescents only, family time predicted fewer depressive symptoms when maternal acceptance was high but more depressive symptoms when maternal acceptance was low. Findings highlight family dynamics as the mechanisms through which familism values have implications for youths’ adjustment. PMID:26778855

Infant acceptance of breast milk after maternal exercise.

PubMed

Wright, Kc S; Quinn, Timothy J; Carey, Gale B

2002-04-01

Previous research reported that breast milk lactic acid (LA) levels increase after lactating women complete a bout of exhaustive exercise, resulting in poor infant acceptance of the postexercise breast milk. This highly publicized finding may not apply to more practical, everyday exercise conditions of lactating women. The purpose of the present study was to reexamine the composition and infant acceptance of postexercise breast milk while controlling maternal diet, exercise intensity, and the method, timing, and assessment of infant feeding. Twenty-four women, 2 to 4 months' postpartum, completed 3 test sessions: a maximal oxygen uptake test, a 30-minute bout of moderate exercise, and a resting control session. One hour before and 1 hour after each session, participants fully expressed their milk, placed it in a bottle familiar to the infant, fed their infant, and rated their infant's acceptance of the milk. Each feeding was videotaped and viewed individually by 3 lactation consultants who rated infant acceptance; consultants were blinded to the test sessions. Milk was analyzed for LA and infant milk consumption was measured. There were no differences in presession versus postsession values for maternal skin temperature, breast milk temperature, and infant milk acceptance as judged by either the mothers or lactation consultants. These results prevailed despite a small but significant increase in breast milk LA premaximal versus postmaximal exercise (0.09 vs 0.21 mM, respectively); there was no difference in milk LA premoderate versus postmoderate exercise, or prerest versus postrest. These data support the hypothesis that moderate or even high-intensity exercise during lactation does not impede infant acceptance of breast milk consumed 1 hour postexercise.

Scholarship for Nuclear Communications and Methods for Evaluation of Nuclear Project Acceptability

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

Golay, Michael

This project aims to go beyond effective communication in understanding how to design nuclear enterprise projects that will gain stakeholder acceptability. Much of what we are studying is generally applicable to controversial projects, and we expect our results to be of broad value beyond the nuclear arena. Acceptability is more than effective communication; it also requires varying degrees of engagement with a disparate number of stakeholder groups. In the nuclear enterprise, previous attempts have been well designed physically (i.e., technologically sound), but have floundered by being insensitive concerning acceptance. Though effective communication is a necessary, but insufficient, condition for suchmore » success, there is a lack of scholarship regarding how to gain stakeholder acceptance for new controversial projects, including nuclear ones. Our work is building a model for use in assessing the performance of a project in the area of acceptability. In the nuclear-social nexus, gaining acceptance requires a clear understanding of factors regarded as being important by the many stakeholders that are common to new nuclear project (many of whom hold an effective veto power). Projects tend to become socially controversial when public beliefs, expert opinion and decision-maker understanding are misaligned. As such, stakeholder acceptance is hypothesized as both an ongoing process and an initial project design parameter comprised of complex, social, cognitive and technical components. Controversial projects may be defined as aspects of modern technologies that some people question, or are cautious about. They could range from genetic modifications, biological hazards, effects of chemical agents, nuclear radiation or hydraulic fracturing operations. We intend that our work will result in a model likely to be valuable for refining project design and implementation to increase the knowledge needed for successful management of stakeholder relationships.« less

Santiago, Régis Tadeu; Teodoro, Tiago Quevedo; Haiduke, Roberto Luiz Andrade

2014-06-21

The nuclear electric quadrupole moment (NQM) of the (63)Cu nucleus was determined from an indirect approach by combining accurate experimental nuclear quadrupole coupling constants (NQCCs) with relativistic Dirac-Coulomb coupled cluster calculations of the electric field gradient (EFG). The data obtained at the highest level of calculation, DC-CCSD-T, from 14 linear molecules containing the copper atom give rise to an indicated NQM of -198(10) mbarn. Such result slightly deviates from the previously accepted standard value given by the muonic method, -220(15) mbarn, although the error bars are superimposed.

The introduction of chromosomal microarray (CMA) into the prenatal setting has involved considerable deliberation due to the wide range of possible outcomes (e.g., copy number variants of uncertain clinical significance). Such issues are typically discussed in pre-test counseling for pregnant women to support informed decision-making regarding prenatal testing options. This research study aimed to assess the level of informed decision-making with respect to prenatal CMA and the factor(s) influencing decision-making to accept CMA for the selected prenatal testing procedure (i.e., chorionic villus sampling or amniocentesis). We employed a questionnaire that was adapted from a three-dimensional measure previously used to assess informed decision-making with respect to prenatal screening for Down syndrome and neural tube defects. This measure classifies an informed decision as one that is knowledgeable, value-consistent, and deliberated. Our questionnaire also included an optional open-ended question, soliciting factors that may have influenced the participants' decision to accept prenatal CMA; these responses were analyzed qualitatively. Data analysis on 106 participants indicated that 49% made an informed decision (i.e., meeting all three criteria of knowledgeable, deliberated, and value-consistent). Analysis of 59 responses to the open-ended question showed that "the more information the better" emerged as the dominant factor influencing both informed and uninformed participants' decisions to accept prenatal CMA. Despite learning about the key issues in pre-test genetic counseling, our study classified a significant portion of women as making uninformed decisions due to insufficient knowledge, lack of deliberation, value-inconsistency, or a combination of these three measures. Future efforts should focus on developing educational approaches and counseling strategies to effectively increase the rate of informed decision-making among women offered prenatal CMA.

Effect of blockage ratio on drag and pressure distributions for bodies of revolution at transonic speeds

1973-01-01

Experimental data were obtained in two wind tunnels for 13 models over a Mach number range from 0.70 to 1.02. Effects of increasing test-section blockage ratio in the transonic region near a Mach number of 1.0 included change in the shape of the drag curves, premature drag creep, delayed drag divergence, and a positive increment of pressures on the model afterbodies. Effects of wall interference were apparent in the data even for a change in blockage ratio from a very low 0.000343 to an even lower 0.000170. Therefore, models having values of blockage ratio of 0.0003 - an order of magnitude below the previously considered safe value of 0.0050 - had significant errors in the drag-coefficient values obtained at speeds near a Mach number of 1.0. Furthermore, the flow relief afforded by slots or perforations in test-section walls - designed according to previously accepted criteria for interference-free subsonic flow - does not appear to be sufficient to avoid significant interference of the walls with the model flow field for Mach numbers very close to 1.0.

Increasing the number of feminist scientists: why feminist aims are not served by the Underdetermination Thesis

NASA Astrophysics Data System (ADS)

Intemann, Kristen

2008-11-01

Recent feminist philosophers of science have argued that feminist values can contribute to rational decisions about which scientific theories to accept. On this view, increasing the number of feminist scientists is important for ensuring rational and objective theory acceptance. The Underdetermination Thesis has played a key role in arguments for this view [Anderson (1995) Hypatia 10(3), 50 84; Hankinson Nelson (1990) Who knows? From Quine to a feminist empiricism. Temple University Press, Philadelphia; Longino (1990) Science as social knowledge. Princeton University Press, Princeton; Longino (2002) The fate of knowledge. Princeton University Press, Princeton; Kourany (2003) Philosophy of Science 70, 1 14]. This thesis is alleged to open an argumentative “gap” between evidence and theory acceptance and provide a rationale for filling the gap with feminist values. While I agree with the conclusion that feminist values can contribute to rational decisions about which theories to accept, I argue that the Underdetermination Thesis cannot support this claim. First, using earlier arguments [Laudan (1990) in: R. Giere (ed) Minnesota studies in the philosophy of science, vol 14, pp 267 297; Slezak (1991) International Studies in Philosophy of Science 5, 241 256; Pinnick (1994) Philosophy of Science 61, 664 657] I show that Underdetermination cannot, by itself, establish that feminist values should fill the gap in theory acceptance. Secondly, I argue that the very use of the Underdetermination Thesis concedes that feminist values are extra-scientific, a-rational, factors in theory acceptance. This concession denies feminists grounds to explain why their values contribute to rational scientific reasoning. Finally, I propose two alternative ways to explain how feminist values can contribute to rational theory acceptance that do not rely on Underdetermination.

Digitally reconstructed radiograph-based study. Using a computer-based method to determine what degree of pelvic rotation is acceptable for measuring the pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS). The effectiveness of a geometrical formula used to calculate the angle of pelvic rotation proposed in a previous article was assessed. It is unclear whether PI, PT, and SS are valid with pelvic rotation while acquiring a radiograph. Ten 3-dimensionally reconstructed models were established with software and placed in a neutral orientation to orient all of the bones in a standing position. Next, 140 digitally reconstructed radiographs were obtained by rotating the models around the longitudinal axis of each pelvis in the software from 0 to 30 degrees at 2.5-degree intervals. PI, PT, and SS were measured. The rotation angle was considered to be acceptable when the change in the measured angle (compared with the "correct" position) was <6 degrees. The rotation angle (α) on the images was calculated by a geometrical formula. Consistency between the measured value and the set angle was assessed. The acceptable maximum angle of rotation for reliable measurements of PI was 17.5 degrees, and the changes in PT and SS were within an acceptable range (<6 degrees) when the pelvic rotation increased from 0 to 30 degrees. The effectiveness of the geometrical formula was shown by the consistency between the set and the calculated rotation angles of the pelvis (intraclass correlation coefficient=0.99). Our study provides insight into the influence of pelvic rotation on the PI, PT, and SS. PI changes with pelvic rotation. The acceptable maximum angle for reliable values of PI, PT, and SS was 17.5 degrees, and the rotation angle of the pelvis on a lateral spinopelvic radiograph can be calculated reliably.

SU-E-T-361: Energy Dependent Radiation/light-Field Misalignment On Truebeam Linear Accelerator

Sperling, N; Tanny, S; Parsai, E

2015-06-15

Purpose: Verifying the co-incidence of the radiation and light field is recommended by TG-142 for monthly and annual checks. On a digital accelerator, it is simple to verify that beam steering settings are consistent with accepted and commissioned values. This fact should allow for physicists to verify radiation-light-field co-incidence for a single energy and accept that Result for all energies. We present a case where the radiation isocenter deviated for a single energy without any apparent modification to the beam steering parameters. Methods: The radiation isocenter was determined using multiple Methods: Gafchromic film, a BB test, and radiation profiles measuredmore » with a diode. Light-field borders were marked on Gafchromic film and then irradiated for all photon energies. Images of acceptance films were compared with films taken four months later. A phantom with a radio-opaque BB was aligned to isocenter using the light-field and imaged using the EPID for all photon energies. An unshielded diode was aligned using the crosshairs and then beam profiles of multiple field sizes were obtained. Field centers were determined using Omni-Pro v7.4 software, and compared to similar scans taken during commissioning. Beam steering parameter files were checked against backups to determine that the steering parameters were unchanged. Results: There were no differences between the configuration files from acceptance. All three tests demonstrated that a single energy had deviated from accepted values by 0.8 mm in the inline direction. The other two energies remained consistent with previous measurements. The deviated energy was re-steered to be within our clinical tolerance. Conclusions: Our study demonstrates that radiation-light-field coincidence is an energy dependent effect for modern linacs. We recommend that radiation-light-field coincidence be verified for all energies on a monthly basis, particularly for modes used to treat small fields, as these may drift without influencing results from other tests.« less

The colorimetric values of two different kinds of esthetic stainless steel crowns were measured and compared with the colorimetric values of primary anterior teeth in Japanese children. The colorimetric values of resin composite-faced stainless steel crowns (Kinder Krown) and epoxy-coated stainless steel crowns (White Steel Crown) were measured with a color difference meter. The Commission Internationale de Eclairage L*, a*, b*, and delta E*ab values and Munsell value, chroma, and hue were calculated. The data were compared with previously reported colorimetric values of Japanese primary anterior teeth measured with the same color difference meter used in this study. Compared to Japanese primary anterior teeth, Kinder Krown Pedo I and Pedo II showed much higher L* values and lower hue; on the other hand, White Steel Crown showed much higher L*, a*, b* values, much higher value and chroma, and much lower hue. Color analysis revealed that the colors of the White Steel Crown and Kinder Krown Pedo I were substantially different from the color of Japanese primary anterior teeth. The color difference between Pedo II crowns and Japanese primary anterior teeth was relatively high, but the color of Pedo II might be acceptable for clinical use.

Infant temperament and feeding history predict infants’ responses to novel foods☆

Moding, Kameron J.; Birch, Leann L.; Stifter, Cynthia A.

2014-01-01

The purpose of the present study was to investigate whether infant temperament and previous feeding history were associated with infants’ acceptance and rejection of a novel food at 12 months of age. Mother–infant dyads (n = 89) were video-recorded during a novel food (hummus, cottage cheese) feeding task. Infants’ reactions (acceptance and rejection behaviors) and maternal responsiveness and affect during the interaction were coded from the recordings by teams of coders. Mothers reported on their infants’ temperamental approach via the Infant Behavior Questionnaire-Revised (IBQ-R) and their infants’ feeding history (previous exposure to solid foods and exclusive breastfeeding). Regression analyses revealed that infants rated lower on approach showed less acceptance of the first offer of novel food than infants rated higher on approach. Additionally, low approach infants who were previously exposed to a greater number of solid foods showed fewer rejection behaviors in response to the later offers of food. Exclusive breastfeeding for 4 months did not appear to have an effect on acceptance or rejection. Finally, greater maternal responsiveness was related to the infants’ acceptance of the new food whereas lower maternal responsiveness was associated with rejection of the novel food. These results suggest that the acceptance and rejection of new foods by infants is dependent upon their temperament and previous exposure to solid foods, as well as the manner in which mothers present the novel food.

Defining acceptable levels for ecological indicators: an approach for considering social values.

PubMed

Smyth, Robyn L; Watzin, Mary C; Manning, Robert E

2007-03-01

Ecological indicators can facilitate an adaptive management approach, but only if acceptable levels for those indicators have been defined so that the data collected can be interpreted. Because acceptable levels are an expression of the desired state of the ecosystem, the process of establishing acceptable levels should incorporate not just ecological understanding but also societal values. The goal of this research was to explore an approach for defining acceptable levels of ecological indicators that explicitly considers social perspectives and values. We used a set of eight indicators that were related to issues of concern in the Lake Champlain Basin. Our approach was based on normative theory. Using a stakeholder survey, we measured respondent normative evaluations of varying levels of our indicators. Aggregated social norm curves were used to determine the level at which indicator values shifted from acceptable to unacceptable conditions. For seven of the eight indicators, clear preferences were interpretable from these norm curves. For example, closures of public beaches because of bacterial contamination and days of intense algae bloom went from acceptable to unacceptable at 7-10 days in a summer season. Survey respondents also indicated that the number of fish caught from Lake Champlain that could be safely consumed each month was unacceptably low and the number of streams draining into the lake that were impaired by storm water was unacceptably high. If indicators that translate ecological conditions into social consequences are carefully selected, we believe the normative approach has considerable merit for defining acceptable levels of valued ecological system components.

2017-01-01

The transmission of positive values between parents and children is generally considered to be the hallmark of successful socialization. As this issue has been widely discussed but surprisingly little researched - especially with reference to core sport values - in this study we aimed to: 1) analyze adolescent athletes’ acceptance of the sport values their parents want to transmit to them (i.e., parental socialization values) and 2) examine the relationship between parental involvement in children’s sportive activity and adolescents’ acceptance of their parents’ socialization values. One hundred and seventy-two Italian adolescents (48.3% male, 51.7% female) who regularly practice team sports were asked to fill out a questionnaire which included the Youth Sport Values Questionnaire – 2 and the Parental Involvement in Sport Questionnaire. The dyadic correlations revealed that young athletes are in general willing to accept their parents’ socialization values in regards to sport. Moreover, from the relative weight analysis (a relatively new data analysis strategy), it emerged that parental involvement characterized by praise and understanding is the most important predictor of adolescents’ willingness to accept their parents’ sport values. Implications of these results and further expansion of the study are discussed. PMID:28344676

Compassionate liberals and polite conservatives: associations of agreeableness with political ideology and moral values.

Hirsh, Jacob B; DeYoung, Colin G; Xiaowen Xu; Peterson, Jordan B

2010-05-01

Political conservatism has been characterized by resistance to change and acceptance of inequality, with liberalism characterized by the polar opposite of these values. Political attitudes are heritable and may be influenced by basic personality traits. In previous research, conservatism (vs. liberalism) has been associated positively with Conscientiousness and negatively with Openness-Intellect, consistent with the association of conservatism with resistance to change. Less clear, however, are the personality traits relating to egalitarianism. In two studies, using a personality model that divides each of the Big Five into two aspects, the present research found that one aspect of Agreeableness (Compassion) was associated with liberalism and egalitarianism, whereas the other (Politeness) was associated with conservatism and traditionalism. In addition, conservatism and moral traditionalism were positively associated with the Orderliness aspect of Conscientiousness and negatively with Openness-Intellect. These findings contribute to a more nuanced understanding of personality's relation to political attitudes and values.

Quality by design for herbal drugs: a feedforward control strategy and an approach to define the acceptable ranges of critical quality attributes.

PubMed

Yan, Binjun; Li, Yao; Guo, Zhengtai; Qu, Haibin

2014-01-01

The concept of quality by design (QbD) has been widely accepted and applied in the pharmaceutical manufacturing industry. There are still two key issues to be addressed in the implementation of QbD for herbal drugs. The first issue is the quality variation of herbal raw materials and the second issue is the difficulty in defining the acceptable ranges of critical quality attributes (CQAs). To propose a feedforward control strategy and a method for defining the acceptable ranges of CQAs for the two issues. In the case study of the ethanol precipitation process of Danshen (Radix Salvia miltiorrhiza) injection, regression models linking input material attributes and process parameters to CQAs were built first and an optimisation model for calculating the best process parameters according to the input materials was established. Then, the feasible material space was defined and the acceptable ranges of CQAs for the previous process were determined. In the case study, satisfactory regression models were built with cross-validated regression coefficients (Q(2) ) all above 91 %. The feedforward control strategy was applied successfully to compensate the quality variation of the input materials, which was able to control the CQAs in the 90-110 % ranges of the desired values. In addition, the feasible material space for the ethanol precipitation process was built successfully, which showed the acceptable ranges of the CQAs for the concentration process. The proposed methodology can help to promote the implementation of QbD for herbal drugs. Copyright © 2013 John Wiley & Sons, Ltd.

2008-07-01

Effects of the dark-cutting condition were examined on commercially slaughtered beef carcass sides that were classified into groups exhibiting 1/3, 1/2, and full degrees of the dark-cutting (DEGDC) condition, as evaluated by a USDA-Agricultural Marketing Service grader (n = 20 per group). Twenty-nine muscles of each carcass side were evaluated to determine the ultimate pH and color (L*, a*, and b*). Fourteen beef muscles (biceps femoris, deep pectoral, chuck complexus, gluteus medius, infraspinatus, latissimus dorsi, psoas major, longissimus thoracis, longissimus lumborum, semimembranosus, semitendinosus, triceps brachii long head, tensor fasciae latae, and vastus lateralis) were evaluated using Warner-Bratzler Shear force (WBSF) and a trained sensory panel. The muscle x DEGDC interaction was significant for ultimate pH, L*, a*, and b* values (P < 0.05). When ultimate pH values of individual muscles were compared with the same muscles evaluated in a previous study, the 1/3, 1/2, and full DEGDC had 7, 9, and 5 muscles, respectively, that fell within a computed 95% prediction limit of what would be considered as a normal pH but were more variable as measured by within-class CV. Color values (L*, a*, and b*) of the muscles from dark-cutting carcasses were numerically lower than those from the normal carcasses. A survey designed to determine the ideal color range of beef lean for retail meat merchandisers (n = 34) and food service chefs (n = 33) across the United States resulted in data analyzed using principal components analysis of L*, a*, and b* values for muscles dissected in the study to estimate the true values for dark-cutting carcasses. Muscles that were within an acceptable color value range for food service chefs had the potential to add between $42.29 to $26.44 and $14.71 to $8.11 per side when valued at Choice and Select prices, respectively. Muscles that were within an acceptable color value range had the potential to add between $30.39 to $16.74 and $10.37 to $5.03 per side for retail meat merchandisers when acceptable muscles were valued at Choice and Select prices, respectively. No muscle x DEGDC interactions were detected for WBSF and sensory panel scores (P > 0.05), but differences were detected among muscles (P < 0.05). Several muscles were considered salvageable from the dark-cutting carcasses that were evaluated, and no significant differences in sensory scores or WBSF between DEGDC classes suggested equal sensory expectations for muscles from dark-cutting carcasses.

Value-based design for the elderly: An application in the field of mobility aids.

In the aging society, the need for the elderly to remain mobile and independent is higher than ever. However, many aids supporting mobility often fail to target real needs and lack acceptance. The aim of this study is to demonstrate how value-based design can contribute to the design of mobility aids that address real needs and thus, lead to high acceptance. We elicited values, facilitators, and barriers of mobility of older adults via ten in-depth interviews. Next, we held co-creation sessions, resulting in several designs of innovative mobility aids, which were evaluated for acceptance via nine in-depth interviews. The interviews resulted in a myriad of key values, such as "independence from family" and "doing their own groceries." Design sessions resulted in three designs for a wheeled walker. Their acceptance was rather low. Current mobility device users were more eager to accept the designs than non-users. The value-based approach offers designers a close look into the lives of the elderly, thereby opening up a wide range of innovation possibilities that better fit their actual needs. Product service systems seem to be a promising focus for targeting human needs in mobility device design.

The Heats of Formation of SiCl+n, for n=1-4

Bauschlicher, Charles W., Jr.; Partridge, Harry; Arnold, James O. (Technical Monitor)

1997-01-01

The heats of formation of SiCl(sub n) and SiCl+(sub n), for n=1-4, have been determined using the G2(B3LYP/MP2/CC) approach. The results for the neutral systems are in very good agreement with previous work. High level calibration calculations show that ion results have about the same accuracy as the neutrals, and allow us to refine the G2(B3LYP/MP2/CC) values. The calculations show that the adiabatic IP of SiCl4 is about 7 kcal/mol smaller than the accepted value. Using a rigid rotor/harmonic oscillator approximation, the temperature dependence of the heat of formation, heat capacity, and entropy are computed for 300 to 4000 K and fit to a polynomial.

Infant temperament and feeding history predict infants' responses to novel foods.

PubMed

Moding, Kameron J; Birch, Leann L; Stifter, Cynthia A

2014-12-01

The purpose of the present study was to investigate whether infant temperament and previous feeding history were associated with infants' acceptance and rejection of a novel food at 12 months of age. Mother-infant dyads (n = 89) were video-recorded during a novel food (hummus, cottage cheese) feeding task. Infants' reactions (acceptance and rejection behaviors) and maternal responsiveness and affect during the interaction were coded from the recordings by teams of coders. Mothers reported on their infants' temperamental approach via the Infant Behavior Questionnaire-Revised (IBQ-R) and their infants' feeding history (previous exposure to solid foods and exclusive breastfeeding). Regression analyses revealed that infants rated lower on approach showed less acceptance of the first offer of novel food than infants rated higher on approach. Additionally, low approach infants who were previously exposed to a greater number of solid foods showed fewer rejection behaviors in response to the later offers of food. Exclusive breastfeeding for 4 months did not appear to have an effect on acceptance or rejection. Finally, greater maternal responsiveness was related to the infants' acceptance of the new food whereas lower maternal responsiveness was associated with rejection of the novel food. These results suggest that the acceptance and rejection of new foods by infants is dependent upon their temperament and previous exposure to solid foods, as well as the manner in which mothers present the novel food.

Louis Essen and the Velocity of Light: From Wartime Radar to Unit of Length

NASA Astrophysics Data System (ADS)

Essen, Ray

2010-03-01

Louis Essen (1908-1997), working at the National Physical Laboratory in Teddington, England, was the first scientist to realize that the value for the velocity of light used widely during World War II was incorrect. In 1947 he published his first determination of it, which was 16 kilometers per second higher than the accepted value, causing a great deal of controversy in the scientific community. His new value was not accepted for several years, until it was shown that it improved the precision of range-finding by radar. Essen’s result has remained as the internationally accepted value despite a number of attempts to improve on it. I discuss Essen’s work and also examine other optical and nonoptical determinations that were made in the United States, and their limits of accuracy. I also identify the reasons why it took so long for Essen’s new value to be accepted, and how it led to changes in the definition of the units of length and time.

The Philpott-Javer postoperative endoscopic mucosal staging system for allergic fungal rhinosinusitis has previously demonstrated acceptable interrater reliability among rhinologists. There are, however, numerous learners involved in patient care at tertiary centers. This study aims to analyze the interrater and intrarater reliability of this system among learners in otolaryngology at different stages in training. A prospective analysis of retrospectively collected endoscopic photographs. A tertiary care teaching hospital (January 2013). Fifty patients undergoing routine follow-up. Three photographs from each of 50 patients undergoing routine postsurgical nasoendoscopy were reviewed. Images were played twice, 1 week apart, in 2 differently randomized cycles and scored according to Philpott-Javer criteria by a rhinologist, a rhinology fellow, a senior otolaryngology resident, a junior otolaryngology resident, and a medical student. Interobserver reliability was assessed using the intraclass correlation coefficient, while intrarater reliability was assessed by Shrout-Fleiss κ values. Agreement between each learner and the rhinologist was also assessed using κ values. The interclass correlation among the 5 raters was 0.7600 (95% confidence interval, 0.6917-0.8161) for the Philpott-Javer scoring system, suggesting substantial reliability. Intrarater data showed substantial to almost-perfect reliability (κ values between 0.668 and 0.815) among all raters using this system. There was also moderate to substantial agreement between the learners and the rhinologist (κ values between 0.534 and 0.710). Results suggest that the Philpott-Javer staging system has acceptable intrarater and interrater reliability among learners of differing levels of clinical experience and is suitable for evaluating progress following surgery.

The agencies method for coalition formation in experimental games

2012-01-01

In society, power is often transferred to another person or group. A previous work studied the evolution of cooperation among robot players through a coalition formation game with a non-cooperative procedure of acceptance of an agency of another player. Motivated by this previous work, we conduct a laboratory experiment on finitely repeated three-person coalition formation games. Human players with different strength according to the coalition payoffs can accept a transfer of power to another player, the agent, who then distributes the coalition payoffs. We find that the agencies method for coalition formation is quite successful in promoting efficiency. However, the agent faces a tension between short-term incentives of not equally distributing the coalition payoff and the long-term concern to keep cooperation going. In a given round, the strong player in our experiment often resolves this tension approximately in line with the Shapley value and the nucleolus. Yet aggregated over all rounds, the payoff differences between players are rather small, and the equal division of payoffs predicts about 80% of all groups best. One reason is that the voting procedure appears to induce a balance of power, independent of the individual player's strength: Selfish subjects tend to be voted out of their agency and are further disciplined by reciprocal behaviors.

The electron donating capacity of biochar is dramatically underestimated

2016-01-01

Biochars have gathered considerable interest for agronomic and engineering applications. In addition to their high sorption ability, biochars have been shown to accept or donate considerable amounts of electrons to/from their environment via abiotic or microbial processes. Here, we measured the electron accepting (EAC) and electron donating (EDC) capacities of wood-based biochars pyrolyzed at three different highest treatment temperatures (HTTs: 400, 500, 600 °C) via hydrodynamic electrochemical techniques using a rotating disc electrode. EACs and EDCs varied with HTT in accordance with a previous report with a maximal EAC at 500 °C (0.4 mmol(e−).gchar−1) and a large decrease of EDC with HTT. However, while we monitored similar EAC values than in the preceding study, we show that the EDCs have been underestimated by at least 1 order of magnitude, up to 7 mmol(e−).gchar−1 for a HTT of 400 °C. We attribute this existing underestimation to unnoticed slow kinetics of electron transfer from biochars to the dissolved redox mediators used in the monitoring. The EDC of other soil organic constituents such as humic substances may also have been underestimated. These results imply that the redox properties of biochars may have a much bigger impact on soil biogeochemical processes than previously conjectured. PMID:27628746

Group acceptance and commitment therapy (ACT) for bipolar disorder and co-existing anxiety - an open pilot study.

PubMed

Pankowski, Sara; Adler, Mats; Andersson, Gerhard; Lindefors, Nils; Svanborg, Cecilia

2017-03-01

Previous studies have supported acceptance and commitment therapy (ACT) for reducing impairment related to various chronic conditions. ACT may possibly be beneficial for bipolar disorder (BD) with co-existing anxiety, which is associated with a poorer treatment outcome. Efforts are needed to identify suitable psychological interventions for BD and co-existing anxiety. In this open clinical trial, we included 26 patients with BD type 1 or 2 at an outpatient psychiatric unit specializing in affective disorders. The intervention consisted of a 12-session manualized group treatment that included psychoeducation, mindfulness, engaging in values-based behaviour, cognitive defusion, acceptance and relapse prevention modules. Participants completed four self-report questionnaires covering anxiety symptoms (Beck Anxiety Inventory - BAI), depressive symptoms (Beck Depression Inventory - BDI-II), quality of life (Quality of Life Inventory - QOLI) and psychological flexibility (Acceptance and Action Questionnaire - AAQ-2) before, during and after the treatment. At post-treatment, the participants reported significant improvements in all outcome measures, with large effects (Cohen's d between 0.73 and 1.98). The mean reduction in anxiety symptoms was 45%. At post-treatment, 96% of the patients were classified as responders on at least one of the outcome measures. A limitation is that the trial is uncontrolled. The results suggest that ACT has the potential to be an effective treatment for BD patients with co-existing anxiety. Further randomized studies are warranted.

Assessment of interchangeability rate between 2 methods of measurements: An example with a cardiac output comparison study.

PubMed

Lorne, Emmanuel; Diouf, Momar; de Wilde, Robert B P; Fischer, Marc-Olivier

2018-02-01

The Bland-Altman (BA) and percentage error (PE) methods have been previously described to assess the agreement between 2 methods of medical or laboratory measurements. This type of approach raises several problems: the BA methodology constitutes a subjective approach to interchangeability, whereas the PE approach does not take into account the distribution of values over a range. We describe a new methodology that defines an interchangeability rate between 2 methods of measurement and cutoff values that determine the range of interchangeable values. We used a simulated data and a previously published data set to demonstrate the concept of the method. The interchangeability rate of 5 different cardiac output (CO) pulse contour techniques (Wesseling method, LiDCO, PiCCO, Hemac method, and Modelflow) was calculated, in comparison with the reference pulmonary artery thermodilution CO using our new method. In our example, Modelflow with a good interchangeability rate of 93% and a cutoff value of 4.8 L min, was found to be interchangeable with the thermodilution method for >95% of measurements. Modelflow had a higher interchangeability rate compared to Hemac (93% vs 86%; P = .022) or other monitors (Wesseling cZ = 76%, LiDCO = 73%, and PiCCO = 62%; P < .0001). Simulated data and reanalysis of a data set comparing 5 CO monitors against thermodilution CO showed that, depending on the repeatability of the reference method, the interchangeability rate combined with a cutoff value could be used to define the range of values over which interchangeability remains acceptable.

Cost-effectiveness acceptability curves and a reluctance to lose.

PubMed

Severens, Johan L; Brunenberg, Daniëlle E M; Fenwick, Elisabeth A L; O'Brien, Bernie; Joore, Manuela A

2005-01-01

Cost-effectiveness acceptability curves (CEACs) are a method used to present uncertainty surrounding incremental cost-effectiveness ratios (ICERs). Construction of the curves relies on the assumption that the willingness to pay (WTP) for health gain is identical to the willingness to accept (WTA) health loss. The objective of this paper is to explore the impact that differences between WTP and WTA health changes have on CEACs. Previous empirical evidence has shown that the relationship between WTP and WTA is not 1:1. The discrepancy between WTP and WTA for health changes can be expressed as a ratio: the accept/reject ratio (which can vary between 1 and infinity). Depending on this ratio, the area within the southwest quadrant of the cost-effectiveness plane in which any bootstrap cost-effect pairs will be considered to be cost effective will be smaller, resulting in a lower CEAC. We used data from two clinical trials to illustrate that relaxing the 1:1 WTP/WTA assumption has an impact on the CEACs. Given the difficulty in assessing the accept/reject ratio for every evaluation, we suggest presenting a series of CEACs for a range of values for the accept/reject ratio, including 1 and infinite. Although it is not possible to explain this phenomenon within the extra-welfarist framework, it has been shown empirically that individuals give a higher valuation to the removal of effective therapies than to the introduction of new therapies that are more costly and effective. In cost-effectiveness analyses where uncertainty of the ICER covers the southwest quadrant of the cost-effectiveness plane, the discrepancy between societies' WTP and WTA should be indicated by drawing multiple CEACs.

An assessment of the performance and quality control procedures of PACS workstation monitors used in Irish radiology departments

Wade, Cherrie; Brennan, Patrick C.; Mc Entee, Mark F.

2005-04-01

Diagnostic efficacy in soft-copy reporting relies heavily on the quality of workstation monitors and an investigation performed in 2002 demonstrated that CRT monitors in Dublin imaging departments were not operating at optimal levels. The current work examines the performance of CRTs being used in Dublin and other parts of Ireland to establish if problems reported in the earlier work have been rectified. All hospitals performing soft-copy reporting for general radiology using CRTs were included in the work. Examination of ambient lighting, calibration of monitors and analysis of CRT performance using the SMPTE test pattern and a selection of the AAPM test images was performed. Maximum luminance, spatial uniformity of luminance, temporal luminance stability, gamma, geometry, sharpness, veiling glare and spatial resolution of each monitor was evaluated. Ambient lighting in all reporting areas was within recommended levels. All the monitors were calibrated appropriately and were performing at acceptable levels for maximum luminance and temporal stability and only one of the thirty-three investigated failed to reach the standard for spatial uniformity. In contrast a number of the CRTs investigated showed poor adherence to acceptable levels for geometrical distortions, veiling glare and spatial resolution all of which are important influencers of image quality. Gamma values also appeared to be low for a number of monitors but this interpretation is provisional and subject to the establishment of ratified guideline values. The results demonstrate that although some improvement on the previous situation is evident, greater adherence to acceptable levels is required for certain parameters.

Potassium Isotopic Compositions of NIST Potassium Standards and 40Ar/39Ar Mineral Standards

NASA Technical Reports Server (NTRS)

Morgan, Leah; Tappa, Mike; Ellam, Rob; Mark, Darren; Higgins, John; Simon, Justin I.

2013-01-01

Knowledge of the isotopic ratios of standards, spikes, and reference materials is fundamental to the accuracy of many geochronological methods. For example, the 238U/235U ratio relevant to U-Pb geochronology was recently re-determined [1] and shown to differ significantly from the previously accepted value employed during age determinations. These underlying values are fundamental to accurate age calculations in many isotopic systems, and uncertainty in these values can represent a significant (and often unrecognized) portion of the uncertainty budget for determined ages. The potassium isotopic composition of mineral standards, or neutron flux monitors, is a critical, but often overlooked component in the calculation of K-Ar and 40Ar/39Ar ages. It is currently assumed that all terrestrial materials have abundances indistinguishable from that of NIST SRM 985 [2]; this is apparently a reasonable assumption at the 0.25per mille level (1s) [3]. The 40Ar/39Ar method further relies on the assumption that standards and samples (including primary and secondary standards) have indistinguishable 40K/39K values. We will present data establishing the potassium isotopic compositions of NIST isotopic K SRM 985, elemental K SRM 999b, and 40Ar/39Ar biotite mineral standard GA1550 (sample MD-2). Stable isotopic compositions (41K/39K) were measured by the peak shoulder method with high resolution MC-ICP-MS (Thermo Scientific NEPTUNE Plus), using the accepted value of NIST isotopic SRM 985 [2] for fractionation [4] corrections [5]. 40K abundances were measured by TIMS (Thermo Scientific TRITON), using 41K/39K values from ICP-MS measurements (or, for SRM 985, values from [2]) for internal fractionation corrections. Collectively these data represent an important step towards a metrologically traceable calibration of 40K concentrations in primary 40Ar/39Ar mineral standards and improve uncertainties by ca. an order of magnitude in the potassium isotopic compositions of standards.

Value Frameworks in Oncology: Comparative Analysis and Implications to the Pharmaceutical Industry.

2017-07-01

As the cost of oncology care continues to rise, composite value models that variably capture the diverse concerns of patients, physicians, payers, policymakers, and the pharmaceutical industry have begun to take shape. To review the capabilities and limitations of 5 of the most notable value frameworks in oncology that have emerged in recent years and to compare their relative value and application among the intended stakeholders. We compared the methodology of the American Society of Clinical Oncology (ASCO) Value Framework (version 2.0), the National Comprehensive Cancer Network Evidence Blocks, Memorial Sloan Kettering Cancer Center DrugAbacus, the Institute for Clinical and Economic Review Value Assessment Framework, and the European Society for Medical Oncology Magnitude of Clinical Benefit Scale, using a side-by-side comparative approach in terms of the input, scoring methodology, and output of each framework. In addition, we gleaned stakeholder insights about these frameworks and their potential real-world applications through dialogues with physicians and payers, as well as through secondary research and an aggregate analysis of previously published survey results. The analysis identified several framework-specific themes in their respective focus on clinical trial elements, breadth of evidence, evidence weighting, scoring methodology, and value to stakeholders. Our dialogues with physicians and our aggregate analysis of previous surveys revealed a varying level of awareness of, and use of, each of the value frameworks in clinical practice. For example, although the ASCO Value Framework appears nascent in clinical practice, physicians believe that the frameworks will be more useful in practice in the future as they become more established and as their outputs are more widely accepted. Along with patients and payers, who bear the burden of treatment costs, physicians and policymakers have waded into the discussion of defining value in oncology care, as well as pharmaceutical companies that seek to understand the impact of these value frameworks on each stakeholder, as they model the value and financial threshold of innovative, high-cost drugs.

Automated characterization of perceptual quality of clinical chest radiographs: Validation and calibration to observer preference

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

Samei, Ehsan, E-mail: samei@duke.edu; Lin, Yuan; Choudhury, Kingshuk R.

Purpose: The authors previously proposed an image-based technique [Y. Lin et al. Med. Phys. 39, 7019–7031 (2012)] to assess the perceptual quality of clinical chest radiographs. In this study, an observer study was designed and conducted to validate the output of the program against rankings by expert radiologists and to establish the ranges of the output values that reflect the acceptable image appearance so the program output can be used for image quality optimization and tracking. Methods: Using an IRB-approved protocol, 2500 clinical chest radiographs (PA/AP) were collected from our clinical operation. The images were processed through our perceptual qualitymore » assessment program to measure their appearance in terms of ten metrics of perceptual image quality: lung gray level, lung detail, lung noise, rib–lung contrast, rib sharpness, mediastinum detail, mediastinum noise, mediastinum alignment, subdiaphragm–lung contrast, and subdiaphragm area. From the results, for each targeted appearance attribute/metric, 18 images were selected such that the images presented a relatively constant appearance with respect to all metrics except the targeted one. The images were then incorporated into a graphical user interface, which displayed them into three panels of six in a random order. Using a DICOM calibrated diagnostic display workstation and under low ambient lighting conditions, each of five participating attending chest radiologists was tasked to spatially order the images based only on the targeted appearance attribute regardless of the other qualities. Once ordered, the observer also indicated the range of image appearances that he/she considered clinically acceptable. The observer data were analyzed in terms of the correlations between the observer and algorithmic rankings and interobserver variability. An observer-averaged acceptable image appearance was also statistically derived for each quality attribute based on the collected individual acceptable ranges. Results: The observer study indicated that, for each image quality attribute, the averaged observer ranking strongly correlated with the algorithmic ranking (linear correlation coefficient R > 0.92), with highest correlation (R = 1) for lung gray level and the lowest (R = 0.92) for mediastinum noise. There was a strong concordance between the observers in terms of their rankings (i.e., Kendall’s tau agreement > 0.84). The observers also generally indicated similar tolerance and preference levels in terms of acceptable ranges, as 85% of the values were close to the overall tolerance or preference levels and the differences were smaller than 0.15. Conclusions: The observer study indicates that the previously proposed technique provides a robust reflection of the perceptual image quality in clinical images. The results established the range of algorithmic outputs for each metric that can be used to quantitatively assess and qualify the appearance quality of clinical chest radiographs.« less

A microfluidic paper-based analytical device for the assay of albumin-corrected fructosamine values from whole blood samples.

Boonyasit, Yuwadee; Laiwattanapaisal, Wanida

2015-01-01

A method for acquiring albumin-corrected fructosamine values from whole blood using a microfluidic paper-based analytical system that offers substantial improvement over previous methods is proposed. The time required to quantify both serum albumin and fructosamine is shortened to 10 min with detection limits of 0.50 g dl(-1) and 0.58 mM, respectively (S/N = 3). The proposed system also exhibited good within-run and run-to-run reproducibility. The results of the interference study revealed that the acceptable recoveries ranged from 95.1 to 106.2%. The system was compared with currently used large-scale methods (n = 15), and the results demonstrated good agreement among the techniques. The microfluidic paper-based system has the potential to continuously monitor glycemic levels in low resource settings.

A web-based survey was used to distribute standardised photographs of beef M. longissimus lumborum with known colorimetrics (L*, a*, b*, hue, chroma, ratio of reflectance at 630nm and 580nm, and estimated deoxymyoglobin, oxymyoglobin and metmyoglobin concentrations) for scrutiny. Consumer demographics and perceived importance of colour to beef value were also evaluated. It was found that a* provided the most simple and robust prediction of beef colour acceptability. Beef colour was considered acceptable (with 95% acceptance) when a* values were equal to or above 14.5. Demographic effects on this threshold were negligible, but consumer nationality and gender did contribute to variation in the relative importance of colour to beef value. These results provide future beef colour studies with context to interpret objective colour measures in terms of consumer acceptance and market appeal. Crown Copyright © 2017.

The aim of this study was to find the difference in perceptibility and acceptability of changes done to various color coordinates of matched teeth, between trainee dental surgeons, and lay person. A photograph with a set of matched central incisor teeth was selected. In one of the central incisors, the color coordinates (hue, value, and chroma) were altered to a preset value. These pictures were presented to trainee dental surgeons and lay person and their level of perception of color change and acceptance of color change was registered and compared. It was found that trainee dental surgeons fared better in perceiving the color change and accepted less of the color changed specimens. The dimension of color that was more discerned both by lay person and trainee dental surgeons was value, hue, and last chroma. When compared to a lay person, dental surgeons are more acute in perceiving color changes and do not accept the color difference between teeth to a higher degree.

This document describes the code CERISE, Code d`Evaluations Radiologiques Individuelles pour des Situations en Enterprise et dans l`Environnement. This code has been developed in the frame of European studies to establish acceptance criteria of very low-level radioactive waste and materials. This code is written in Fortran and runs on PC. It calculates doses received by the different pathways: external exposure, ingestion, inhalation and skin contamination. Twenty basic scenarios are already elaborated, which have been determined from previous studies. Calculations establish the relation between surface, specific and/or total activities, and doses. Results can be expressed as doses for an average activitymore » unit, or as average activity limits for a set of reference doses (defined for each scenario analyzed). In this last case, the minimal activity values and the corresponding limiting scenarios, are selected and summarized in a final table.« less

2016-01-01

This study explores Chinese nurses' acceptance of PDA, using a questionnaire based on the framework of Technology Acceptance Model (TAM). 357 nurses were involved in the study. The results reveal the scores of the nurses' acceptance of PDA were means 3.18~3.36 in four dimensions. The younger of nurses, the higher nurses' title, the longer previous usage time, the more experienced using PDA, and the more acceptance of PDA. Therefore, the hospital administrators may change strategies to enhance nurses' acceptance of PDA, and promote the wide application of PDA.

Residential surface soil guidance applied worldwide to the pesticides added to the Stockholm Convention in 2009 and 2011.

PubMed

Jennings, Aaron A; Li, Zijian

2015-09-01

Due to the widespread use of agricultural and residential pesticides, the potential for pesticide soil contamination is a worldwide concern. In response, regulatory jurisdictions in at least 54 nations have promulgated guidance values to specify the maximum allowable concentration of pesticides in soils. Guidance values may be found for more than 700 pesticides. A previous analysis examined the values applied to the original "dirty dozen" persistent organic pollutant (POP) pesticides that were addressed in the 2001 Stockholm Convention (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene). Results are presented here for the "new POP" pesticides that were added to the Stockholm Convention in 2009 and 2011 (isomers of Hexachlorocyclohexane, Chlordecone, and isomers of Endosulfan). The guidance value extremes used worldwide for these pesticides vary by as much as 8.5 orders of magnitude and the randomness in their distributions resembles that of lognormal random variables. However, there are nonrandom value clusters in some distributions that may identify values around which consensuses are forming. The current value distributions imply that a wide range of human health risks are being accepted. Hopefully, the results presented will help regulatory jurisdictions and the regulated communities identify values that should be revised to be adequately protective of human health.

Costa, Ana Maria; de Paula, Lilian Marly; Bezerra, Ana Cristina Barreto

2008-01-01

The purpose of this study was to evaluate the use of a laser fluorescence device for detection of occlusal caries in permanent teeth. One hundred and ninety-nine non-cavitated teeth from 26 patients aged 10 to 13 years were selected. After dental prophylaxis, two previously calibrated dentists examined the teeth. Visual inspection, radiographic examination and laser measurements were performed under standardized conditions. The validation method was cavity preparation with a small cone-shaped diamond bur, when the two examiners agreed about the presence of dentin caries. It was found that the laser detection method produced high values of sensitivity (0.93) and specificity (0.75) and a moderate positive predictive value (0.63). The laser device showed the lowest value of likelihood ratio (3.68). Kappa coefficient showed good repeatability for all methods. Although the laser device had an acceptable performance, this equipment should be used as an adjunct method to visual inspection to avoid false positive results. PMID:19089284

Rapid determination of octanol-water partition coefficient using vortex-assisted liquid-liquid microextraction.

2014-02-21

Vortex-assisted liquid-liquid microextraction (VALLME) coupled with high-performance liquid chromatography (HPLC) is proposed here for the rapid determination of octanol-water partitioning coefficients (Kow). VALLME uses vortex agitation, a mild emulsification procedure, to disperse microvolumes of octanol in the aqueous phase thus increasing the interfacial contact area and ensuring faster partitioning rates. With VALLME, 2min were enough to achieve equilibrium conditions between the octanolic and aqueous phases. Upon equilibration, separation was achieved using centrifugation and the octanolic microdrop was collected and analyzed in a HPLC system. Six model compounds with logKow values ranging between ∼0.5 and 3.5 were used during the present investigations. The proposed method produced logKow values that were consistent with previously published values and the recorded uncertainty was well within the acceptable log unit range. Overall, the key features of the proposed Kow determination procedure comprised speed, reliability, simplicity, low cost and minimal solvent consumption. Copyright © 2014 Elsevier B.V.

2013-04-01

Overpressure is one important cause of domino effect in accidents of chemical process equipments. Some models considering propagation probability and threshold values of the domino effect caused by overpressure have been proposed in previous study. In order to prove the rationality and validity of the models reported in the reference, two boundary values of three damage degrees reported were considered as random variables respectively in the interval [0, 100%]. Based on the overpressure data for damage to the equipment and the damage state, and the calculation method reported in the references, the mean square errors of the four categories of damage probability models of overpressure were calculated with random boundary values, and then a relationship of mean square error vs. the two boundary value was obtained, the minimum of mean square error was obtained, compared with the result of the present work, mean square error decreases by about 3%. Therefore, the error was in the acceptable range of engineering applications, the models reported can be considered reasonable and valid.

2015-01-01

Background Mobile apps for people with diabetes offer great potential to support therapy management, increase therapy adherence, and reduce the probability of the occurrence of accompanying and secondary diseases. However, they are rarely used by elderly patients due to a lack of acceptance. Objective We investigated the question “Which factors influence the acceptance of diabetes apps among patients aged 50 or older?” Particular emphasis was placed on the current use of mobile devices/apps, acceptance-promoting/-inhibiting factors, features of a helpful diabetes app, and contact persons for technical questions. This qualitative study was the third of three substudies investigating factors influencing acceptance of diabetes apps among patients aged 50 or older. Methods Guided interviews were chosen in order to get a comprehensive insight into the subjective perspective of elderly diabetes patients. At the end of each interview, the patients tested two existing diabetes apps to reveal obstacles in (first) use. Results Altogether, 32 patients with diabetes were interviewed. The mean age was 68.8 years (SD 8.2). Of 32 participants, 15 (47%) knew apps, however only 2 (6%) had already used a diabetes app within their therapy. The reasons reported for being against the use of apps were a lack of additional benefits (4/8, 50%) compared to current therapy management, a lack of interoperability with other devices/apps (1/8, 12%), and no joy of use (1/8, 12%). The app test revealed the following main difficulties in use: nonintuitive understanding of the functionality of the apps (26/29, 90%), nonintuitive understanding of the menu navigation/labeling (19/29, 66%), font sizes and representations that were too small (14/29, 48%), and difficulties in recognizing and pressing touch-sensitive areas (14/29, 48%). Furthermore, the patients felt the apps lacked individually important functions (11/29, 38%), or felt the functions that were offered were unnecessary for their own therapy needs (10/29, 34%). The most important contents of a helpful diabetes app were reported as the ability to add remarks to measured values (9/28, 32%), the definition of thresholds for blood glucose values and highlighting deviating values (7/28, 25%), and a reminder feature for measurement/medication (7/28, 25%). The most important contact persons for technical questions were family members (19/31, 61%). Conclusions A lack of additional benefits and ease of use emerged as the key factors for the acceptance of diabetes apps among patients aged 50 or older. Furthermore, it has been shown that the needs of the investigated target group are highly heterogeneous due to varying previous knowledge, age, type of diabetes, and therapy. Therefore, a helpful diabetes app should be individually adaptable. Personal contact persons, especially during the initial phase of use, are of utmost importance to reduce the fear of data loss or erroneous data input, and to raise acceptance among this target group.

1996-01-01

Loin steaks were eaten by 67 consumers over a 15-wk period (n = 739 consumer observations) to determine the consumer acceptability of beef tenderness in the home and a "white table cloth" restaurant. Steaks were rated for tenderness, juiciness, flavor, and overall palatability on an 8-point scale. The acceptability levels for tenderness were established based on Warner-Bratzler shear (WBS) force values, tenderness ratings, and a chisquare analysis of the judgment of tenderness and overall acceptability by the same consumers in both the home and restaurant. Results based only on observations from consumers in Lubbock, TX indicated that the beef industry should target production of beef steaks that have a Warner-Bratzler shear force value of 4.1 kg or less to ensure high levels (98%) of consumer acceptability. Results suggest that an acceptable level of beef tenderness for consumers can be determined and WBS values can be used as criteria for determining which steaks will be considered acceptably tender to consumers before distribution to retail outlets. The beef industry needs to conduct a nationwide research study to determine whether the results from this study will apply to all U.S. beef consumers.

Social acceptance is a confession, compilation, and appreciation for an individual which come from other individual or social groups in their entirety which makes individual feels safe, comfortable, and their existence is appreciated. A cross-sectional study consisted of 42 pulmonary TB patients registered at Puskesmas Amplas was done to analyze their social acceptance in the society. Data was collected by direct interview using structured questionnaire. The result showed that majority had either high and very high social acceptance with 45.20% and 31.0% respectively with high family support and high self-confidence (73.8%). Bivariate analysis showed a significant association between family support and self confidence with social acceptance (p value<0.05). The correlation coefficient (r) of self confidenceis 0.629 while family support were is 0.455 (p-value<0.05). This study concludes that both family support and self-confidence have a significant correlation with social acceptance.

Introduction Parents play a key role in the development of eating habits in preschool children, as they are the food "gatekeepers." Repeated exposure to new foods can improve child food preferences and consumption. The objective of this study was to determine parent feeding strategies used to influence child acceptance of previously rejected foods (PRF). Methods We conducted eighteen focus groups (total participants = 111) with low-income African American and Hispanic parents of preschool children (3- to 5-year-olds) in Texas, Colorado, and Washington. Through thematic analysis, we coded transcripts and analyzed coded quotes to develop dominant emergent themes related to strategies used to overcome children's food refusal. Results We found three major themes in the data: parents most often do not serve PRF; parents value their child eating over liking a food; and parents rarely use the same feeding strategy more than once for a PRF. Desiring to reduce waste and save time, parents said they most often intentionally decided not to purchase or serve PRF to their children. Discussion Because parents' primary goal in child feeding is getting children to eat (over acceptance of a variety of foods), strategies to help parents promote consumption of less easily accepted foods could help parents with child feeding struggles and improve children's dietary quality.

Aim: The aim of this study was to find the difference in perceptibility and acceptability of changes done to various color coordinates of matched teeth, between trainee dental surgeons, and lay person. Materials and Methods: A photograph with a set of matched central incisor teeth was selected. In one of the central incisors, the color coordinates (hue, value, and chroma) were altered to a preset value. These pictures were presented to trainee dental surgeons and lay person and their level of perception of color change and acceptance of color change was registered and compared. Results: It was found that trainee dental surgeons fared better in perceiving the color change and accepted less of the color changed specimens. The dimension of color that was more discerned both by lay person and trainee dental surgeons was value, hue, and last chroma. Conclusion: When compared to a lay person, dental surgeons are more acute in perceiving color changes and do not accept the color difference between teeth to a higher degree. PMID:26538933

Dupuytren's disease: current state of the art.

PubMed

Henry, Mark

2014-03-01

This review article critically examines the current literature for Dupuytren's disease. Five procedures are considered: dermofasciectomy, limited fasciectomy, segmental aponeurectomy, needle aponeurotomy, and collagenase injection. Studies regarding the efficacy of these treatments focus primarily on the initial degree of correction, rate of recurrence, and complications. No one treatment has been declared superior and substantial controversy exists. Comparison between studies has been hampered by the absence of uniform definitions for clinical success and measurable disease progression. Traditional post-operative care includes formal therapy and night splinting, but recent studies have questioned the value of these adjuncts. The extent of involvement at which the surgeon should intervene was previously well accepted by convention, but as the paradigm shifts towards less invasive procedures, treatment may be offered at an earlier stage. Future research should be structured to recognize the value-based decision making used by patients when selecting treatment.

Glass Effect in Inbreeding-Avoidance Systems: Minimum Viable Population for Outbreeders

NASA Astrophysics Data System (ADS)

Tainaka, Kei-ichi; Itoh, Yoshiaki

1996-10-01

Many animals, birds and plants have evolved mechanisms to avoid inbreeding between close relatives.Such mating systems may have developed several methods for restricting mate choice.If fragmentation of habitats becomes serious, these methods may lead to a lack of acceptable mates. We call this “glass effect”which is a generalization of the so-called Allee effect.We present two inbreeding-avoidance (outbreeding) models.Both models show that outbreeders have a high risk infragmented environments.We thus obtain the minimum viable population (MVP). It is found that the value of MVP amounts to the range from several hundred to several thousand individuals.While this value is much larger than thoseobtained by the previous demographic theories,it is consistent with recent empirical estimations.Moreover, we find that the glass effect is caused bydynamically induced clusters of relatives.This suggests that genetic variation will be decreased by the outbreeding in a highly fragmented environment.

Pathways to happiness are multidirectional: Associations between state mindfulness and everyday affective experience.

PubMed

Blanke, Elisabeth S; Riediger, Michaela; Brose, Annette

2018-03-01

Mindfulness is commonly defined as a multidimensional mode of being attentive to, and aware of, momentary experiences while taking a nonjudgmental and accepting stance. These qualities have been linked to 2 different facets of affective well-being: being attentive is proposed to lead to an appreciation of experiences as they are, and thus to positive affect (PA). Accepting unpleasant experiences in a nonjudgmental fashion has been hypothesized to reduce negative affect (NA). Alternatively, however, attention may increase both positive and negative affectivity, whereas nonjudgmental acceptance may modify how people relate to their experiences. Previous research has considered such differential associations at the trait level, although a mindful mode may be understood as a state of being. Using an experience-sampling methodology (ESM) with smartphones, the present research therefore links different state mindfulness facets to positive and NA in daily life. Seventy students (50% female, 20-30 years old) of different disciplines participated in the study. Based on multidimensional assessments of self-reported state mindfulness and state affect, the findings corroborate the hypotheses on the differential predictive value of 2 mindfulness facets: Participants experienced more PA when they were attentive to the present moment and less NA when they nonjudgmentally accepted momentary experiences. Furthermore, only nonjudgmental acceptance buffered the impact of daily hassles on affective well-being. The study contributes to a more fine-grained understanding of the within-person mechanisms relating mindfulness to affective well-being in daily life. Future interventions may be able to enhance different aspects of affective well-being by addressing specific facets of mindfulness. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Atopic eczema or dermatitis (AD) is associated with atopy and is characterized by reduced skin hydration and an impaired skin barrier in the epidermis. We investigated the patient acceptability and efficacy of an emollient containing ceramide-precursor lipids and moisturizing factors (LMF) in AD. Consecutive AD patients were recruited. Swabs and cultures were obtained from the right antecubital fossa and the worst-affected eczematous area, and disease severity [according to the SCORing Atopic Dermatitis (SCORAD) Index], skin hydration, and transepidermal water loss (TEWL) were measured prior to and after 2 weeks' use of the LMF moisturizer. The general acceptability of treatment was documented as being 'very good', 'good', 'fair', or 'poor'. Twenty-four AD patients [mean age 13.8 (standard deviation 5.7) years] were recruited. Two thirds of the patients reported very good or good acceptability of the LMF moisturizer, whereas one third reported fair or poor acceptability. There were no inter-group differences in the pre-use clinical parameters of age, objective SCORAD score, pruritus score, sleep disturbance score, skin hydration, TEWL, topical corticosteroid use, oral antihistamine use, or acceptability of previously used proprietary emollients. However, patients in the fair/poor acceptability group were more likely to have Staphylococcus aureus colonization and to be female (odds ratio 13, 95 % confidence interval 1.7-99.4; p = 0.021). Following use of the LMF moisturizer, the objective SCORAD score, pruritus score, and sleep disturbance score were lower in the very good/good acceptability group than in the fair/poor acceptability group. The mean objective SCORAD score improved (from 31.5 to 25.7; p = 0.039) and skin hydration improved [from 30.7 arbitrary units (a.u.) to 36.0 a.u.; p = 0.021] in the very good/good acceptability group. When the data were analyzed for the strength of the agreement of the rating of acceptability, the κ values were 0.338 (fair) for use of body wash and 0.118 (poor) for use of emollients before and after the trial. The LMF moisturizer was considered acceptable by two thirds of the patients with AD. It seems that patients who found the moisturizer acceptable were less likely to be female or to be colonized by S. aureus before switching to the product, and they had less severe eczema, less pruritus, and less sleep disturbance after its use than patients who did not find the product acceptable. Gender and S. aureus colonization may have influenced the patient acceptability and clinical efficacy of the LMF moisturizer. The lack of agreement with regard to the acceptability of the moisturizer implies that there is room for parent/patient education to improve compliance.

The aim of this study was to objectively assess the patients' acceptance for awake craniotomy in a group of neurosurgical patients, who underwent this procedure for removal of lesions in or close to eloquent brain areas. Patients acceptance for awake craniotomy under local anesthesia and conscious sedation was assessed by a formal questionnaire (PPP33), initially developed for general surgery patients. The results are compared to a group of patients who had brain surgery under general anesthesia and to previously published data. The awake craniotomy (AC) group consisted of 37 male and 9 female patients (48 craniotomies) with age ranging from 18 to 71 years. The general anesthesia (GA) group consisted of 26 male and 15 female patients (43 craniotomies) with age ranging from 26 to 83 years. All patients in the study were included in the questionnaire analysis. In comparison to GA the overall PPP33 score for AC was higher (p=0.07), suggesting better overall acceptance for AC. The subscale scores for AC were also significantly better compared to GA for the two subscales "postoperative pain" (p=0.02) and "physical disorders" (p=0.01) and equal for the other 6 subscales. The results of the overall mean score and the scores for the subscales of the PPP33 questionnaire verify good patients' acceptance for AC. Previous studies have shown good patients' acceptance for awake craniotomy, but only a few times using formal approaches. By utilizing a formal questionnaire we could verify good patient acceptance for awake craniotomy for the treatment of brain tumors in or close to eloquent areas. This is a novel approach that substantiates previously published experiences. Copyright © 2011 Elsevier B.V. All rights reserved.

Beam Output Auditing (BOA) is one key process of the EORTC radiation therapy quality assurance program. Here the results obtained between 2005 and 2014 are presented and compared to previous results.For all BOA reports the following parameters were scored: centre, country, date of audit, beam energies and treatment machines audited, auditing organisation, percentage of agreement between stated and measured dose.Four-hundred and sixty-one BOA reports were analyzed containing the results of 1790 photon and 1366 electron beams, delivered by 755 different treatment machines. The majority of beams (91.1%) were within the optimal limit of ≤ 3%. Only 13 beams (0.4%; n = 9 electrons; n = 4 photons), were out of the range of acceptance of ≤ 5%. Previous reviews reported a much higher percentage of 2.5% or more of the BOAs with >5% deviation.The majority of EORTC centres present beam output variations within the 3% tolerance cutoff value and only 0.4% of audited beams presented with variations of more than 5%. This is an important improvement compared to previous BOA results.

Introduction: Radiographers evaluate anatomical structures to judge clinical acceptability of a radiograph. Whether a radiograph is deemed acceptable for diagnosis or not depends on the individual decision of the radiographer. Individual decisions cause variation in the accepted image quality. To minimise these variations definitions of acceptability, such as in RadLex, were developed. On which criteria radiographers attribute a RadLex categories to radiographs is unknown. Insight into these criteria helps to further optimise definitions and reduce variability in acceptance between radiographers. Therefore, this work aims the evaluation of the correlation between the RadLex classification and the evaluation of anatomical structures, using a Visual Grading Analysis (VGA) Methods: Four radiographers evaluated the visibility of five anatomical structures of 25 lateral cervical spine radiographs on a secondary class display with a VGA. They judged clinical acceptability of each radiograph using RadLex. Relations between VGAS and RadLex category were analysed with Kendall's Tau correlation and Nagelkerke pseudo-R². Results: The overall VGA score (VGAS) and the RadLex score correlate (rτ= 0.62, p<0.01, R2=0.72) strongly. The observers' evaluation of contrast between bone, air (trachea) and soft tissue has low value in predicting (rτ=0.55, p<0.01, R2=0.03) the RadLex score. The reproduction of spinous processes (rτ=0.67, p<0.01, R2=0.31) and the evaluation of the exposure (rτ=0.65, p<0.01, R2=0.56) have a strong correlation with high predictive value for the RadLex score. Conclusion: RadLex scores and VGAS correlate positively, strongly and significantly. The predictive value of bony structures may support the use of these in the judgement of clinical acceptability. Considerable inter-observer variations in the VGAS within a certain RadLex category, suggest that observers use of observer specific cut-off values.

[Possibility of using flour of pigeon pea in products prepared with rice or wheat flour].

The present study reports on the development of foods containing processed pigeon pea (Cajanus cajan) flour. The pigeon pea flours described in a previous publication were prepared from dehulled pigeon peas by cooking in autoclave, by extrusion-cooking and by cooking/dehydration by drum-drying. Mixtures of cooked pigeon peas and rice were first evaluated biological through a protein complementation design using NPR. The results of this study showed that the two products had high protein quality and were similar when mixed in ratios of 80:20 to 40:60. For the evaluation of the processed pigeon pea flour, mixtures with rice (80:20) were used. All pigeon pea flours gave similar protein quality values. On the basis of these results three products were developed and tested. One was a gruel ("atole"), a second a fruit-flavored thick drink with and without 15% milk. Cookies were also prepared with a series of blends of pigeon pea flour (extrusion-cooked) and wheat. The gruel and the fruit flavored products had high acceptability based on a sensory evaluation test. Cookies with 100% pigeon pea flour were unacceptable, however, mixtures of 75% wheat flour and 25% pigeon pea flour gave cookies of attractive appearance and good taste. The study showed the possibility of preparing and utilizing tropical grain legume flours for food products of relatively high acceptability and nutritive value.

Relationships of consumer sensory ratings, marbling score, and shear force value to consumer acceptance of beef strip loin steaks.

Logistic regression was used to quantify and characterize the effects of changes in marbling score, Warner-Bratzler shear force (WBSF), and consumer panel sensory ratings for tenderness, juiciness, or flavor on the probability of overall consumer acceptance of strip loin steaks from beef carcasses (n = 550). Consumers (n = 489) evaluated steaks for tenderness, juiciness, and flavor using nine-point hedonic scales (1 = like extremely and 9 = dislike extremely) and for overall steak acceptance (satisfied or not satisfied). Predicted acceptance of steaks by consumers was high (> 85%) when the mean consumer sensory rating for tenderness,juiciness, or flavor for a steak was 3 or lower on the hedonic scale. Conversely, predicted consumer acceptance of steaks was low (< or = 10%) when the mean consumer rating for tenderness, juiciness, or flavor for a steak was 5 or higher on the hedonic scale. As mean consumer sensory ratings for tenderness, juiciness, or flavor decreased from 3 to 5, the probability of acceptance of steaks by consumers diminished rapidly in a linear fashion. These results suggest that small changes in consumer sensory ratings for these sensory traits have dramatic effects on the probability of acceptance of steaks by consumers. Marbling score displayed a weak (adjusted R2 = 0.053), yet significant (P < 0.01), relationship to acceptance of steaks by consumers, and the shape of the predicted probability curve for steak acceptance was approximately linear over the entire range of marbling scores (Traces67 to Slightly Abundant97), suggesting that the likelihood of consumer acceptance of steaks increases approximately 10% for each full marbling score increase between Slight to Slightly Abundant. The predicted probability curve for consumer acceptance of steaks was sigmoidal for the WBSF model, with a steep decline in predicted probability of acceptance as WBSF values increased from 3.0 to 5.5 kg. Changes in WBSF within the high (> 5.5 kg) or low (< 3.0 kg) portions of the range of WBSF values had little effect on the probability of consumer acceptance of steaks.

The effect of survivalism--self-expressionism culture on black male suicide acceptability: a cross-national analysis.

PubMed

Stack, Steven; Kposowa, Augustine J

2011-04-01

Cultural explanations of black suicide have focused on the US and stressed religiosity as a protective factor. This paper adds to this literature by (1) expanding the analysis of the impact of religiosity on black suicide to 10 nations, and (2) assessing the extent to which a broader cultural construct (self expressionism) affects black suicide acceptability. Data are from Wave 4 of the World Values Surveys 1991-2001 and refer to 3580 black males nested in ten countries. A hierarchical linear regression model determined that religiosity predicted black suicide acceptability across ten nations. Self expressionism was positively associated with individual level suicide acceptability. Further, a cross-level interaction was found wherein individual level and societal level self expressionism combined to affect suicide acceptability. The variability in suicide acceptability among black males is predicted, in part, by both individual and group levels of adherence to values contained in a major cultural axis of nations: self expressionism. These new found associations compliment the impact of a standard predictor, religiosity, on suicide acceptability. Copyright © 2011 Elsevier Ltd. All rights reserved.

Relationship between consumer ranking of lamb colour and objective measures of colour.

2010-06-01

Given the lack of data that relates consumer acceptance of lamb colour to instrument measures a study was undertaken to establish the acceptability thresholds for fresh and displayed meat. Consumers (n=541) were asked to score 20 samples of lamb loin (m.longissimus thoracis et lumborum; LL) on an ordinal scale of 1 (very acceptable) to 5 (very unacceptable). A sample was considered acceptable by a consumer if it scored three or less. Ten samples were used for testing consumer response to fresh colour and 10 to test consumer response to colour during display of up to 4days. The colour of fresh meat was measured using a Minolta chromameter with a closed cone and a Hunter Lab Miniscan was used for measuring meat on display. For fresh meat when the a( *) (redness) and L( *) (lightness) values are equal to or exceed 9.5 and 34, respectively, on average consumers will consider the meat colour acceptable. However a( *) and L( *) values must be much higher (14.5 and 44, respectively) to have 95% confidence that a randomly selected consumer will consider a sample acceptable. For aged meat, when the wavelength ratio (630/580nm) and the a( *) values are equal to or greater than 3.3 and 14.8, respectively, on average consumers will consider the meat acceptable. These thresholds need to be increased to 6.8 for ratio (630/580nm) and 21.7 for a( *) to be 95% confident that a randomly selected consumer will consider a sample acceptable. Crown Copyright 2010.

The aim of this study was to compare vertical and horizontal adjustments of castable abutments after conducting casting and soldering procedures. Twelve external hexagonal implants (3.75 × 10 mm) and their UCLA abutments were divided according their manufacturer and abutment type: PUN (plastic UCLA, Neodent), PUC (plastic UCLA, Conexão), PU3i (plastic UCLA, Biomet 3i), and PUTN (plastic UCLA with Tilite milled base, Neodent). Three infrastructures of a fixed partial implant-supported bridge with 3 elements were produced for each group. The measurements of vertical (VM) and horizontal (HM) misfits were obtained via scanning electron microscopy after completion of casting and soldering. The corresponding values were determined to be biomechanically acceptable to the system, and the results were rated as a percentage. Statistical analysis establishes differences between groups by chi-square after procedures, and McNeman's test was applied to analyze the influence of soldering over casting (α ≤ .05). For the values of VM and HM, respectively, when the casting process was complete, it was observed that 83.25% and 100% (PUTN), 33.3% and 27.75% (PUN), 33.3% and 88.8% (PUC), 33.3% and 94.35% (PU3i) represented acceptable values. After completing the requisite soldering, acceptable values were 50% and 94.35% (PUTN), 16.6% and 77.7% (PUN), 38.55% and 77.7% (PUC), and 27.75% and 94.35% (PU3i). Within the limitations of this study, it can be concluded that the premachined abutments presented more acceptable VM values. The HM values were within acceptable limits before and after the soldering procedure for most groups. Further, the soldering procedure resulted in an increase of VM in all groups.

The role of phosphates for the Lu-Hf chronology of meteorites

The 176Lu-176Hf isotopic system is widely used for dating and tracing cosmochemical and geological processes, but still suffers from two uncertainties. First, Lu-Hf isochrons for some early Solar System materials have excess slope of unknown origin that should not be expected for meteorites with ages precisely determined with other isotopic chronometers. This observation translates to an apparent Lu decay constant higher than the one calculated by comparing ages obtained with various dating methods on terrestrial samples. Second, unlike the well constrained Sm/Nd value (to within 2%) for the chondritic uniform reservoir (CHUR), the Lu/Hf ratios in chondrites vary up to 18% when considering all chondrites, adding uncertainty to the Lu/Hf CHUR value. In order to better understand the Lu-Hf systematics of chondrites, we analyzed mineral fractions from the Richardton H5 chondrite to construct an internal Lu-Hf isochron, and set up a numerical model to investigate the effect of preferential diffusion of Lu compared to Hf from phosphate, the phase with the highest Lu-Hf ratio in chondrites, to other minerals. The isochron yields an age of 4647 ± 210 million years (Myr) using the accepted 176Lu decay constant of 1.867 ± 0.008 ×10-11yr-1. Combining this study with the phosphate fractions measured in a previous study yields a slope of 0.08855 ± 0.00072, translating to a 176Lu decay constant of 1.862 ± 0.016 ×10-11yr-1 using the Pb-Pb age previously obtained, in agreement with the accepted value. The large variation of the Lu/Hf phosphates combined with observations in the present study identify phosphates as the key in perturbing Lu-Hf dating and generating the isochron slope discrepancy. This is critical as apatite has substantially higher diffusion rates of rare earth elements than most silicate minerals that comprise stony meteorites. Results of numerical modeling depending of temperature peak, size of the grains and duration of the metamorphic event, show that diffusion processes in phosphate can produce an apparently older Lu-Hf isochron, while this effect will remain negligible in perturbing the Sm-Nd chronology. Our results suggest that only type 3 chondrites with the lowest metamorphic grade and large minerals with minimal diffusive effects are suitable for determination of the Lu-Hf CHUR values and the Lu decay constant respectively.

A new line for preparation of the graphite samples for 14C dating by Accelerator Mass Spectrometry (AMS) in the Zagreb Radiocarbon Laboratory has been validated by preparing graphite from various materials distributed within the Fifth International Radiocarbon Intercomparison (VIRI) study. 14C activity of prepared graphite was measured at the SUERC AMS facility. The results are statistically evaluated by means of the z-score and u-score values. The mean z-score value of 28 prepared VIRI samples is (0.06 ± 0.23) showing excellent agreement with the consensus VIRI values. Only one sample resulted in the u-score value above the limit of acceptability (defined for the confidence interval of 99%) and this was probably caused by a random contamination of the graphitization rig. After the rig had been moved to the new adapted and isolated room, all u-score values laid within the acceptable limits. Our LSC results of VIRI intercomparison samples are also presented and they are all accepted according to the u-score values.

Culturally-Competent Treatments for Asian Americans: The Relevance of Mindfulness and Acceptance-Based Psychotherapies

2011-01-01

The development of effective treatments for Asian Americans is important because treatment disparities continue to exist for this population. Because of their theoretical grounding in East Asian philosophies, mindfulness and acceptance-based psychotherapies appear to constitute promising ways to provide culturally responsive mental health care to Asian Americans. However, in practice these approaches often reflect conceptions of mental health that are more consistent with Western world views. We review points of intersection and divergence between Western-based mindfulness and acceptance psychotherapies and Asian American cultural values. We then propose a culturally syntonic approach that accentuates certain components of mindfulness and acceptance psychotherapies and adapts other components of these approaches to be more consistent with Asian American cultural values.

Physician Payment Methods and the Patient-Centered Medical Home: Comment on "A Troubled Asset Relief Program for the Patient-Centered Medical Home".

PubMed

Quinn, Kevin

This commentary analyzes the patient-centered medical home (PCMH) model within a framework of the 8 basic payment methods in health care. PCMHs are firmly within the fee-for-service tradition. Changes to the process and structure of the Resource Based Relative Value Scale, which underlies almost all physician fee schedules, could make PCMHs more financially viable. Of the alternative payment methods being considered, shared savings models are unlikely to transform medical practice whereas capitation models place unrealistic expectations on providers to accept epidemiological risk. Episode payment may strike a feasible balance for PCMHs, with newly available episode definitions presenting opportunities not previously available.

The magic of 4X mask reduction

Lercel, Michael

2006-06-01

Although changing the mask reduction factor from 4X to a larger value offers several technical advantages, previous attempts to enact this change have not identified enough clear technical advantages to overcome the impact to productivity. Improvements in mask manufacturing, mask polarization effects, and optics cost have not been thought to be sufficient reason to accept a reduced throughput and field size. This paper summarizes the latest workshop and discussion revisiting the mask reduction factor for 32nm half-pitch lithography with hyper-numerical aperture (NA) optical or extreme ultraviolet lithography (EUVL). The workshop consensus was strongly in favor of maintaining the current magnification ratio and field size as long as mask costs can be contained.

Variability of prediction of maximal oxygen concumption on the cycle ergometer using standard equations

Greenisen, Michael C.; Fortney, Suzanne M.; Lee, Stuart M. C.; Moore, Alan D.; Barrows, Linda H.

1993-01-01

Several investigations within the Exercise Countermeasures Project at the NASA Johnson Space Center focused on the assessment of maximum oxygen consumption (VO2(sub max)) within the Astronaut Corps pre- and postspace flight. Investigations during the Apollo era suggested that there was a significant decrease in postflight VO2(sub max) when compared to preflight values, and current studies have documented that this trend continues in the Space Shuttle era. It is generally accepted and was confirmed in our laboratory that VO2(sub max) can be predicted from submaximal measures taken during graded exercise tests on the cycle ergometer with respect to populations. However, previous work had not examined the effect of day-to-day variations in the physiologic responses that might alter these predictions for individuals. Stability of individual submaximal data over serial tests is important so that predicted changes in VO2(sub max) are reflective of actual VO2(sub max) changes. Therefore, the purpose of this investigation was to determine which of the accepted equations to predict VO2(sub max) would be less affected by normal daily physiologic changes.

Previous research has identified a set of core factors that influence moral judgments. The present study addresses the interplay between moral judgments and four factors: (a) incidental affects, (b) sociocultural context, (c) type of dilemma, and (d) participant's sex. We asked participants in two different countries (Colombia and Spain) to judge the acceptability of actions in response to personal and impersonal moral dilemmas. Before each dilemma an affective prime (erotic, pleasant or neutral pictures) was presented suboptimally. Our results show that: a) relative to neutral priming, erotic primes increase the acceptance of harm for a greater good (i.e., more utilitarian judgments), b) relative to Colombians, Spanish participants rated causing harm as less acceptable, c) relative to impersonal dilemmas, personal dilemmas reduced the acceptance of harm, and d) relative to men, women were less likely to consider harm acceptable. Our results are congruent with findings showing that sex is a crucial factor in moral cognition, and they extend previous research by showing the interaction between culture and incidental factors in the making of moral judgments.

Charge and energy dependence of the residence time of cosmic ray nuclei below 15 GeV/nucleon

1985-01-01

The relative abundance of nuclear species measured in cosmic rays at Earth has often been interpreted with the simple leaky box model. For this model to be consistent an essential requirement is that the escape length does not depend on the nuclear species. The discrepancy between escape length values derived from iron secondaries and from the B/C ratio was identified by Garcia-Munoz and his co-workers using a large amount of experimental data. Ormes and Protheroe found a similar trend in the HEAO data although they questioned its significance against uncertainties. They also showed that the change in the B/C ratio values implies a decrease of the residence time of cosmic rays at low energies in conflict with the diffusive convective picture. These conclusions crucially depend on the partial cross section values and their uncertainties. Recently new accurate cross sections of key importance for propagation calculations have been measured. Their statistical uncertainties are often better than 4% and their values significantly different from those previously accepted. Here, these new cross sections are used to compare the observed B/C+O and (Sc to Cr)/Fe ratio to those predicted with the simple leaky box model.

Monitoring health interventions – who's afraid of LQAS?

Pezzoli, Lorenzo; Kim, Sung Hye

2013-01-01

Lot quality assurance sampling (LQAS) is used to evaluate health services. Subunits of a population (lots) are accepted or rejected according to the number of failures in a random sample (N) of a given lot. If failures are greater than decision value (d), we reject the lot and recommend corrective actions in the lot (i.e. intervention area); if they are equal to or less than d, we accept it. We used LQAS to monitor coverage during the last 3 days of a meningitis vaccination campaign in Niger. We selected one health area (lot) per day reporting the lowest administrative coverage in the previous 2 days. In the sampling plan we considered: N to be small enough to allow us to evaluate one lot per day, deciding to sample 16 individuals from the selected villages of each health area, using probability proportionate to population size; thresholds and d to vary according to administrative coverage reported; α ≤5% (meaning that, if we would have conducted the survey 100 times, we would have accepted the lot up to five times when real coverage was at an unacceptable level) and β ≤20% (meaning that we would have rejected the lot up to 20 times, when real coverage was equal or above the satisfactory level). We classified all three lots as with the acceptable coverage. LQAS appeared to be a rapid, simple, and statistically sound method for in-process coverage assessment. We encourage colleagues in the field to consider using LQAS in complement with other monitoring techniques such as house-to-house monitoring. PMID:24206650

Patients' reactions to attempts to increase passive or active coping with surgery.

1998-09-01

It is generally regarded as valuable for patients to exercise control over aspects of their medical treatment. Although psychological and other interventions are commonly used with the aim of increasing patients' ability or willingness to control events, it is not known whether patients experience these procedures in the way assumed. The present study compared responses to (i) a psychological intervention designed to increase patients' readiness to exercise control and cope actively and (ii) a comparable intervention intended to induce acceptance and passive coping. Hip or knee arthroplasty patients were visited preoperatively by a researcher who administered the active (N = 15) or passive (N = 15) intervention in a dialogue with the patient. Patients' verbal responses to the interventions were analyzed qualitatively to identify the range of reactions to each type of intervention. Patients readily accepted the passive message on the grounds of doctors' and nurses' authority and the value of the patients' emotional detachment from their surgery. Few responses to the active message indicated acceptance that patients have control over their care and its outcomes; instead, recipients typically interpreted it in terms of the need for obedience to medical and nursing authority. In conclusion, patients do not automatically accept messages intended to change ways of coping. In particular, the attempt to increase patients' readiness to take control over aspects of care can be perceived by patients in an opposite way to that intended. This and previous studies suggest that patient control over aspects of treatment is a professional and theoretical construction that often means little to patients.

Muscle hardness is a mechanical property that represents transverse muscle stiffness. A quantitative method that uses ultrasound elastography for quantifying absolute human muscle hardness has been previously devised; however, its reliability and validity have not been completely verified. This study aimed to verify the reliability and validity of this quantitative method. The Young's moduli of seven tissue-mimicking materials (in vitro; Young's modulus range, 20-80 kPa; increments of 10 kPa) and the human medial gastrocnemius muscle (in vivo) were quantified using ultrasound elastography. On the basis of the strain/Young's modulus ratio of two reference materials, one hard and one soft (Young's moduli of 7 and 30 kPa, respectively), the Young's moduli of the tissue-mimicking materials and medial gastrocnemius muscle were calculated. The intra- and inter-investigator reliability of the method was confirmed on the basis of acceptably low coefficient of variations (≤6.9%) and substantially high intraclass correlation coefficients (≥0.77) obtained from all measurements. The correlation coefficient between the Young's moduli of the tissue-mimicking materials obtained using a mechanical method and ultrasound elastography was 0.996, which was equivalent to values previously obtained using magnetic resonance elastography. The Young's moduli of the medial gastrocnemius muscle obtained using ultrasound elastography were within the range of values previously obtained using magnetic resonance elastography. The reliability and validity of the quantitative method for measuring absolute muscle hardness using ultrasound elastography were thus verified.

Research suggests that psychological inflexibility may drive procrastination. Accordingly, interventions using acceptance and mindfulness methods to increase psychological flexibility may decrease procrastination. This study compared time management and acceptance-based behavioral interventions. College students' predictions of how much assigned reading they should complete were compared to what they did complete. Procrastination, anxiety, psychological flexibility, and academic values were also measured. Although a trend suggested that time management intervention participants completed more reading, no group differences in procrastination were revealed. The acceptance-based behavioral intervention was most effective for participants who highly valued academics. Clinical implications and future research are discussed.

Religion and suicide acceptability: a cross-national analysis.

PubMed

Stack, Steven; Kposowa, Augustine J

2011-01-01

Four perspectives (moral community thesis, religious integration, religious commitment, and social networks) guide the selection of variables in this study. Data are from the combined World Values/European Values Surveys for 2000 (50,547 individuals nested in 56 nations). The results of a multivariate hierarchical linear model support all four perspectives. Persons residing in nations with relatively high levels of religiosity, who are affiliated with one of four major faiths, are religiously committed, and are engaged with a religious network are found to be lower in suicide acceptability. The religious integration perspective, in particular, is empirically supported; affiliation with Islam is associated with low suicide acceptability. The findings provide strong support for an integrated model and demonstrate the usefulness of the moral community thesis in understanding suicide acceptability.

This study investigated the use of Acceptance and Commitment Therapy (ACT) as a treatment for music performance anxiety (MPA) in an uncontrolled pilot design. ACT is a newer, “third-wave” therapy that differs from previous MPA treatments, because its goal is not to reduce symptoms of MPA. Rather, ACT aims to enhance psychological flexibility in the presence of unwanted symptoms through the promotion of six core processes collectively known as the ACT “Hexaflex.” A small group of student vocalists (N = 7) from an elite choral college were recruited using objective criteria for evaluating MPA. Participants received 12 ACT sessions, and their baseline functioning served as a pre-treatment control. Treatment consisted of an orientation to ACT, identifying experientially avoidant behaviors, facilitation of Hexaflex processes, group performances in which valued behaviors were practiced in front of one another, meditations, homework, and completion of self-report measures before, during, and after treatment (at a 1- and 3-month follow-up). Improvements were observed in participants' cognitive defusion, acceptance of MPA symptoms, and psychological flexibility at post-treatment and follow-ups. Students also appeared to improve their performance quality and reduce their shame over having MPA. These results add to existing research suggesting ACT is a promising intervention for MPA, while also highlighting how vocal students may be less impaired by physical MPA symptoms. PMID:28674509

Short-beaked echidnas (Tachyglossus aculeatus) are myrmecophages, or ant and termite insectivore specialists, and replicating their exact diet in captivity is problematic. Diets for captive animals often incorporate raw meat, eggs and cat food mixed together with water, and vitamin and mineral supplements. These diets have promoted a number of health problems in captive echidnas, such as gastritis, cystitis, gut impaction, obesity, and diarrhea. A manufactured diet was designed and three echidnas from two zoos were transitioned onto this diet to assess the acceptability and digestibility of this diet for echidnas. The new "test" diet was readily accepted by the echidnas with a 1 week transition period. Daily digestible energy intake was 280 kJ kg -0.75 d -1 , similar to another myrmecophagous species. Digestibility values were above 74% for all macronutrients. It was determined that this diet was an acceptable replacement for the previous diets and it was decided that the remaining echidnas at both institutions would be transitioned to the new diet. The diet will also be used for wild echidnas being rehabilitated in the zoo hospitals prior to release and commercially available within Australia. Further data are being collected to assess the use of this diet for seasonal weight management, transitioning hand-reared puggles and effects on gastrointestinal tract health.

Laboratory experiments were conducted to determine the effective pressure law for permeability of tight sandstone rocks from the E-bei gas reservoir, China. The permeability k of five core samples was measured while cycling the confining pressure pc and fluid pressure pf. The permeability data were analyzed using the response-surface method, a statistical model-building approach yielding a representation of k in (pc, pf) space that can be used to determine the effective pressure law, i.e., peff = pc - κpf. The results show that the coefficient κ of the effective pressure law for permeability varies with confining pressure and fluid pressure as well as with the loading or unloading cycles (i.e., hysteresis effect). Moreover, κ took very small values in some of the samples, even possibly lower than the value of porosity, in contradiction with a well-accepted theoretical model. We also reanalyzed a previously published permeability data set on fissured crystalline rocks and found again that the κ varies with pc but did not observe κ values lower than 0.4, a value much larger than porosity. Analysis of the dependence of permeability on effective pressure suggests that the occurrence of low κ values may be linked to the high-pressure sensitivity of E-bei sandstones.

Physicians' evaluations of patients' decisions to refuse oncological treatment

Objective: To gain insight into the standards of rationality that physicians use when evaluating patients' treatment refusals. Design of the study: Qualitative design with indepth interviews. Participants: The study sample included 30 patients with cancer and 16 physicians (oncologists and general practitioners). All patients had refused a recommended oncological treatment. Results: Patients base their treatment refusals mainly on personal values and/or experience. Physicians mainly emphasise the medical perspective when evaluating patients' treatment refusals. From a medical perspective, a patient's treatment refusal based on personal values and experience is generally evaluated as irrational and difficult to accept, especially when it concerns a curative treatment. Physicians have a different attitude towards non-curative treatments and have less difficulty accepting a patient's refusal of these treatments. Thus, an important factor in the physician's evaluation of a treatment refusal is whether the treatment refused is curative or non-curative. Conclusion: Physicians mainly use goal oriented and patients mainly value oriented rationality, but in the case of non-curative treatment refusal, physicians give more emphasis to value oriented rationality. A consensus between the value oriented approaches of patient and physician may then emerge, leading to the patient's decision being understood and accepted by the physician. The physician's acceptance is crucial to his or her attitude towards the patient. It contributes to the patient's feeling free to decide, and being understood and respected, and thus to a better physician–patient relationship. PMID:15738431

Clinically Useful Spirometry in Preschool-Aged Children: Evaluation of the 2007 American Thoracic Society Guidelines

Rationale In 2007 the American Thoracic Society (ATS) recommended guidelines for acceptability and repeatability for assessing spirometry in preschool children. The authors aim to determine the feasibility of spirometry among children in this age group performing spirometry for the first time in a busy clinical practice. Methods First-time spirometry for children age 4 to 5 years old was selected from the Children’s Hospital Boston Pulmonary Function Test (PFT) database. Maneuvers were deemed acceptable if (1) the flow-volume loop showed rapid rise and smooth descent; (2) the back extrapolated volume (Vbe), the volume leaked by a subject prior to the forced maneuver, was ≤80 ml and 12.5% of forced vital capacity (FVC); and (3) cessation of expiratory flow was at a point ≤10% of peak expiratory flow rate (PEFR). Repeatability was determined by another acceptable maneuver with forced expiratory volume in t seconds (FEVt) and FVC within 10% or 0.1 L of the best acceptable maneuver. Post hoc analysis compared spirometry values for those with asthma and cystic fibrosis to normative values. Results Two hundred and forty-eight preschool children performed spirometry for the first time between August 26, 2006, and August 25, 2008. At least one technically acceptable maneuver was found in 82.3% (n = 204) of the tests performed. Overall, 54% of children were able to perform acceptable and repeatable spirometry based on the ATS criteria. Children with asthma or cystic fibrosis did not have spirometry values that differed significantly from healthy controls. However, up to 29% of the overall cohort displayed at least one abnormal spirometry value. Conclusions Many preschool-aged children are able to perform technically acceptable and repeatable spirometry under normal conditions in a busy clinical setting. Spirometry may be a useful screen for abnormal lung function in this age group. PMID:20653495

Conjoint Analysis (CJA), a statistical market-based technique that assesses the value consumers place on product characteristics, may be used to predict acceptability of hypothetical products. Rectal Microbicides (RM)-substances that would prevent HIV infection during receptive anal intercourse-will require acceptability data from potential users in multiple settings to inform the development process by providing valuable information on desirable product characteristics and issues surrounding potential barriers to product use. This study applied CJA to explore the acceptability of eight different hypothetical RM among 128 MSM in Lima and Iquitos, Peru; Guayaquil, Ecuador; and Rio de Janeiro, Brazil. Overall RM acceptability was highest in Guayaquil and lowest in Rio. Product effectiveness had the greatest impact on acceptability in all four cities, but the impact of other product characteristics varied by city. This study demonstrates that MSM from the same region but from different cities place different values on RM characteristics that could impact uptake of an actual RM. Understanding specific consumer preferences is crucial during RM product development, clinical trials and eventual product dissemination.

Free-Riding Behavior in Vaccination Decisions: An Experimental Study

2014-01-01

Individual decision-making regarding vaccination may be affected by the vaccination choices of others. As vaccination produces externalities reducing transmission of a disease, it can provide an incentive for individuals to be free-riders who benefit from the vaccination of others while avoiding the cost of vaccination. This study examined an individual's decision about vaccination in a group setting for a hypothetical disease that is called “influenza” using a computerized experimental game. In the game, interactions with others are allowed. We found that higher observed vaccination rate within the group during the previous round of the game decreased the likelihood of an individual's vaccination acceptance, indicating the existence of free-riding behavior. The free-riding behavior was observed regardless of parameter conditions on the characteristics of the influenza and vaccine. We also found that other predictors of vaccination uptake included an individual's own influenza exposure in previous rounds increasing the likelihood of vaccination acceptance, consistent with existing empirical studies. Influenza prevalence among other group members during the previous round did not have a statistically significant effect on vaccination acceptance in the current round once vaccination rate in the previous round was controlled for.

Recently, the use of the truncated area under the curve from 0 to 2 h (AUC(0-2)) of mycophenolic acid (MPA) has been proposed for therapeutic monitoring in liver transplant recipients. The aim of our study was the evaluation of the clinical usefulness of truncated AUC(0-2) in kidney transplant patients. Plasma MPA was measured in samples taken before the morning dose of mycophenolate mofetil, and one-half and 2 h post-dose, completing 63 MPA concentration-time profiles from 40 adult kidney transplant recipients. The AUC from 0 to 12 h (AUC(0-12)) was calculated using the validated algorithm of Pawinski et al. The truncated AUC(0-2) was calculated using the linear trapezoidal rule, and extrapolated to 0-12 h (trapezoidal extrapolated AUC(0-12)) as previously described. Algorithm calculated and trapezoidal extrapolated AUC(0-12) values showed high correlation (r=0.995) and acceptable dispersion (ma68=0.71 μg·h/mL), median prediction error (6.6%) and median absolute prediction error (12.6%). The truncated AUC(0-2) had acceptable diagnostic efficiency (87%) in the classification of subtherapeutic, therapeutic or supratherapeutic values with respect to AUC(0-12). However, due to the high inter-individual variation of the drug absorption-rate, the dispersion between both pharmacokinetic variables (ma68=6.9 μg·h/mL) was unacceptable. The substantial dispersion between truncated AUC(0-2) and AUC(0-12) values may be a serious objection for the routine use of MPA AUC(0-2) in clinical practice.

This paper aims to estimate the temperature equivalent to 10% (T10%), 50% (T50%) and 90% (T90%) of distilled volume in crude oils using (1)H NMR and support vector regression (SVR). Confidence intervals for the predicted values were calculated using a boosting-type ensemble method in a procedure called ensemble support vector regression (eSVR). The estimated confidence intervals obtained by eSVR were compared with previously accepted calculations from partial least squares (PLS) models and a boosting-type ensemble applied in the PLS method (ePLS). By using the proposed boosting strategy, it was possible to identify outliers in the T10% property dataset. The eSVR procedure improved the accuracy of the distillation temperature predictions in relation to standard PLS, ePLS and SVR. For T10%, a root mean square error of prediction (RMSEP) of 11.6°C was obtained in comparison with 15.6°C for PLS, 15.1°C for ePLS and 28.4°C for SVR. The RMSEPs for T50% were 24.2°C, 23.4°C, 22.8°C and 14.4°C for PLS, ePLS, SVR and eSVR, respectively. For T90%, the values of RMSEP were 39.0°C, 39.9°C and 39.9°C for PLS, ePLS, SVR and eSVR, respectively. The confidence intervals calculated by the proposed boosting methodology presented acceptable values for the three properties analyzed; however, they were lower than those calculated by the standard methodology for PLS.

Neural mechanisms of economic commitment in the human medial prefrontal cortex

2014-01-01

Neurobiologists have studied decisions by offering successive, independent choices between goods or gambles. However, choices often have lasting consequences, as when investing in a house or choosing a partner. Here, humans decided whether to commit (by acceptance or rejection) to prospects that provided sustained financial return. BOLD signals in the rostral medial prefrontal cortex (rmPFC) encoded stimulus value only when acceptance or rejection was deferred into the future, suggesting a role in integrating value signals over time. By contrast, the dorsal anterior cingulate cortex (dACC) encoded stimulus value only when participants rejected (or deferred accepting) a prospect. dACC BOLD signals reflected two decision biases–to defer commitments to later, and to weight potential losses more heavily than gains–that (paradoxically) maximised reward in this task. These findings offer fresh insights into the pressures that shape economic decisions, and the computation of value in the medial prefrontal cortex.

The objective was to determine the acceptability to women of oral emergency contraception (EC) that works by inhibiting ovulation, preventing implantation or disrupting implantation, and also to determine the characteristics of women associated with the acceptability of each posited mechanism of action. Women completed a self-administered, anonymous questionnaire asking whether they would consider using an EC pill based on each of three hypothetical mechanisms of action: inhibiting ovulation, preventing implantation or disrupting implantation. The questionnaire was distributed among women in Edinburgh, UK, (a) presenting for EC at a community pharmacy, (b) attending a clinic for insertion of intrauterine contraception (IUC) or (c) attending a clinic for an induced abortion. Descriptive analyses stratified women according to healthcare setting and personal characteristics. Univariable and multivariable analyses were used to establish factors which may predict acceptability of each EC pill's mechanism of action. Four hundred and nineteen out of 458 (91%) women responded to the survey. Overall, women reported that EC would be acceptable if it worked by inhibiting ovulation (89%), preventing implantation (83%) or disrupting implantation (75%). Among women seeking abortion, more would accept an EC pill which disrupted implantation compared to women seeking IUC (odds ratio, 2.19; 95% confidence interval, 1.30-3.69; p=.004). Based on multivariable analyses, factors associated with acceptability included previous use of EC, previously holding strong views against abortion and having had a previous abortion. For each of the posited mechanisms of action, a majority of women surveyed would be willing to consider oral EC to prevent unintended pregnancy. The scope of the study was limited, and further work on the views of women in the wider population is needed. This is important as the development of such drugs to prevent pregnancy is likely to raise political and ethical challenges, particularly in relation to disruption of implantation.

The influenza vaccine is recommended in older population. However the immunization coverage varies globally. It has been reported as low as 10-20 % in some countries. This study explored the acceptance of and willingness to pay for influenza vaccination, comparing acceptance and willingness to pay before and after health education. The study was conducted with 2693 older people in Bangkok, Thailand. Participants were divided into an education group (n = 1402) and a control group (n = 1291). A validated questionnaire measuring acceptance of and willingness to pay for vaccination was administered during semi-structured interviews before and after education. Data on factors influencing acceptance were analyzed. Participants' mean age was 69.5 years, 80 % were women and 82.1 % had at least one co-morbidity. Of the participants, 43.5 % had previously received vaccination more than once, although 92.8 % expressed acceptance of vaccination. Acceptance was associated with a positive attitude toward vaccination (OR 2.1, 95 % CI 1.5-2.9) and a history of receiving vaccination (OR 4.1, 95 % CI 2.8-6.1). At baseline, there were no differences between the education and control groups in terms of work status (p = 0.457), co-morbidities (p = 0.07), medical status (p = 0.243), and previous vaccination (p = 0.62), except for educational background (p = 0.004). Acceptance of vaccination increased to 95.8 % (p < 0.001) after education and willingness to pay increased to 82.1 % (p < 0.001). Education significantly affected those with primary school-level education and no previous vaccination history, with acceptance increasing from 83.3 to 92.6 % (p < 0.001); more than twice as high as the control group (OR 2.4, 95 % CI 1.2-4.7). Viewing an educational video increased the proportion of participants with a high level of knowledge from 29.2 to 49.2 % (p < 0.001), and increased the proportion of participants with a positive attitude from 52.4 to 70.7 % (p <0.001). No significant difference was found in any parameter between the first and second assessment in the control group. The strategies to increase positive attitudes may enhance the acceptance of vaccination. Health education using an educational video demonstrated a significant impact on acceptance, willingness to pay, knowledge and attitude in older people. This may lead to increased sustainability of the immunization program in older people.

Measurements of the kinetics of the reaction of OH with HNO3, and mechanisms of HNO3 removal from the stratosphere, are reported. Bimolecular rate constants were determined at temperatures between 224 and 366 K by monitoring the concentrations of OH radicals produced by HNO3 photolysis and HNO3 according to their resonance fluorescence and 184.9-nm absorption, respectively. The rate constant measured at 298 K is found to be somewhat faster than previously accepted values, with a negative temperature dependence. Calculations of a one-dimensional transport-kinetic atmospheric model on the basis of the new rate constant indicate reductions in O3 depletion due to chlorofluoromethane release and NOx injection, of magnitudes dependent on the nature of the reaction products.

The "We Card" program: tobacco industry "youth smoking prevention" as industry self-preservation.

PubMed

Apollonio, Dorie E; Malone, Ruth E

2010-07-01

The "We Card" program is the most ubiquitous tobacco industry "youth smoking prevention" program in the United States, and its retailer materials have been copied in other countries. The program's effectiveness has been questioned, but no previous studies have examined its development, goals, and uses from the tobacco industry's perspective. On the basis of our analysis of tobacco industry documents released under the 1998 Master Settlement Agreement, we concluded that the We Card program was undertaken for 2 primary purposes: to improve the tobacco industry's image and to reduce regulation and the enforcement of existing laws. Policymakers should be cautious about accepting industry self-regulation at face value, both because it redounds to the industry's benefit and because it is ineffective.

Ethically and legally, assertions that resuscitation is in a patient's best interest should be inversely correlated with willingness to forego intensive care (and accept comfort care) at the surrogate's request. Previous single country studies have demonstrated a relative devaluation of neonates when compared with other critically ill patients. In this international study, physicians in Argentina, Australia, Canada, Ireland, The Netherlands, Norway and the United States were presented with eight hypothetical vignettes of incompetent critically ill patients of different ages. They were asked to make assessments about best interest, respect for surrogate autonomy and to rank the patients in a triage scenario. In total, 2237 physicians responded (average response rate 61%). In all countries and scenarios, participants did not accept to withhold resuscitation if they estimated it was in the patient's best interest, except for scenarios involving neonates. Young children (other than neonates) were given high priority for resuscitation, regardless of existing disability. For neonates, surrogate autonomy outweighed assessment of best interest. In all countries, a 2-month-old-infant with meningitis and a multiply disabled 7-year old were resuscitated first in the triage scenario, with more variable ranking of the two neonates, which were ranked below patients with considerably worse prognosis. The value placed on the life of newborns is less than that expected according to predicted clinical outcomes and current legal and ethical theory relative to best interests. Value assessments on the basis of age, disability and prognosis appear to transcend culture, politics and religion in this domain.

The Women's Health Questionnaire (WHQ) is a validated and commonly used instrument for measuring climacteric-related symptoms. A revised version was previously developed. However, validation in a Finnish population is lacking. As it is important to use qualified instruments, we performed a validation study of the WHQ in a Finnish population. In all, 3,421 women, aged 41 to 54 years, formed the study population. In the original 36-item WHQ, the items were rated on a 1 to 4 scale and on a binary scale (0-1). The scaling of the revised 23-item WHQ was 0 to 100. We evaluated the psychometric properties (internal consistency, correlations between the symptom domains, factor structure, and sampling adequacy) in all three versions. For the 1 to 4 scale and on the revised version of the WHQ, the internal consistency was acceptable (the Cronbach's α coefficients >0.70) for most of the domains. On the binary scale, the majority of the coefficient values were below the acceptable level. The original symptom domains, especially those on the revised version, were recognizable from the factors in the exploratory factor analysis, but there were some limitations. The Kaiser-Meyer-Olkin values were high. The WHQ is a valid instrument for measuring climacteric-related symptoms in Finnish middle-aged women. The psychometric properties of the revised 23-item WHQ were as good or even better than those of the original 36-item WHQ. Thus, we encourage use of the revised version.

Tissue-mimicking phantoms, including bovine serum albumin phantoms and egg white phantoms, have been developed for, and in laboratory use for, real-time visualization of high intensity focused ultrasound-induced thermal coagulative necrosis since 2001. However, until now, very few data are available concerning their thermophysical properties. In this article, a step-wise transient plane source method has been used to determine the values of thermal conductivity, thermal diffusivity, and specific heat capacity of egg white phantoms with elevated egg white concentrations (0 v/v% to 40 v/v%, by 10 v/v% interval) at room temperature (~20 °C). The measured thermophysical properties were close to previously reported values; the thermal conductivity and thermal diffusivity were linearly proportional to the egg white concentration within the investigation range, while the specific heat capacity decreased as the egg white concentration increased. Taking account of large differences between real experiment and ideal model, data variations within 20 % were accepted.

The Workplace Experiences of Women with Fibromyalgia.

Fibromyalgia (FM) is a common pain syndrome that mostly affects women. Chronic pain and other symptoms often chalenge work for women with FM. This study aimed to explore how women with FM experience their work situations. A purposive sample of 15 women with FM was interviewed with in-depth qualitative interviews. Data were analysed using a hermeneutic approach. The results revealed that women with FM experienced incapacity to work as they had previously and eventually accepted that their work life had changed or reached its end. Since their work had great significance in their lives, feelings of loss and sorrow were common. Women who were working, unemployed, or on sick leave described feelings of fear for their future work situations. Women with FM greatly value their work. Their wish to perform work as before is however, not consistent with their abilities. As such, women with FM need support in continuing to work for as long as possible, after which they need support in finding new values in life. Copyright © 2016 John Wiley & Sons, Ltd.

Talar chondral defects can be a source of persistent ankle pain and disability. If untreated, there is an increased risk of osteoarthritis. The purpose of our study was to determine diagnostic accuracy of 3T MRI in detecting Outerbridge grades 3 and 4 articular cartilage lesions of the talus in a clinical setting, utilizing a standardized clinical MRI protocol. Patients who had a 3T ankle MRI and subsequent ankle surgery, by a single surgeon, were included in this study. MRI exams were performed 180 days or less before surgery. Seventy-nine ankles in 78 patients (mean age of 42.3 years) were included in this study. Mean body mass index was 26.3. A standard clinical MRI exam was performed on a 3T MRI scanner. Mean days from MRI to surgery was 39 days. All MRI exams were read and findings recorded by a musculoskeletal radiologist. Arthroscopic examination was performed by a single orthopaedic surgeon. Detailed arthroscopic findings and demographic data were collected prospectively and stored in a data registry. Of the 78 patients, 31 (39.2%) reported previous ankle surgery. Pain was the primary reason for seeking medical attention as reported by 95% of patients, followed by instability in 44% and loss of function with 42%. Prevalence of Outerbridge grade 3 and 4 talar articular cartilage defects identified at arthroscopy was 17.7%. The 3T MRI demonstrated a sensitivity of 0.714, specificity of 0.738, positive predictive value of 0.370, and negative predictive value of 0.923. Sensitivity and specificity levels were acceptable for detection of grades 3 and 4 articular cartilage defects of the talar dome using 3T MRI. The high negative predictive value may be beneficial in preoperative planning. While these values are acceptable, a high index of suspicion should be maintained in the appropriate clinical setting. © The Author(s) 2014.

Measuring surface topography with scanning electron microscopy. I. EZEImage: a program to obtain 3D surface data.

PubMed

Ponz, Ezequiel; Ladaga, Juan Luis; Bonetto, Rita Dominga

2006-04-01

Scanning electron microscopy (SEM) is widely used in the science of materials and different parameters were developed to characterize the surface roughness. In a previous work, we studied the surface topography with fractal dimension at low scale and two parameters at high scale by using the variogram, that is, variance vs. step log-log graph, of a SEM image. Those studies were carried out with the FERImage program, previously developed by us. To verify the previously accepted hypothesis by working with only an image, it is indispensable to have reliable three-dimensional (3D) surface data. In this work, a new program (EZEImage) to characterize 3D surface topography in SEM has been developed. It uses fast cross correlation and dynamic programming to obtain reliable dense height maps in a few seconds which can be displayed as an image where each gray level represents a height value. This image can be used for the FERImage program or any other software to obtain surface topography characteristics. EZEImage also generates anaglyph images as well as characterizes 3D surface topography by means of a parameter set to describe amplitude properties and three functional indices for characterizing bearing and fluid properties.

Becker, Curtis A.; Hayes, Brian C.; Gorman, Patrick C.

1991-01-01

User acceptance of new support systems typically was evaluated after the systems were specified, designed, and built. The current study attempts to assess user acceptance of an Automatic-Aided Target Recognition (ATR) system using an emulation of such a proposed system. The detection accuracy and false alarm level of the ATR system were varied systematically, and subjects rated the tactical value of systems exhibiting different performance levels. Both detection accuracy and false alarm level affected the subjects' ratings. The data from two experiments suggest a cut-off point in ATR performance below which the subjects saw little tactical value in the system. An ATR system seems to have obvious tactical value only if it functions at a correct detection rate of 0.7 or better with a false alarm level of 0.167 false alarms per square degree or fewer.

Grammaticality, Acceptability, and Probability: A Probabilistic View of Linguistic Knowledge.

PubMed

Lau, Jey Han; Clark, Alexander; Lappin, Shalom

2017-07-01

The question of whether humans represent grammatical knowledge as a binary condition on membership in a set of well-formed sentences, or as a probabilistic property has been the subject of debate among linguists, psychologists, and cognitive scientists for many decades. Acceptability judgments present a serious problem for both classical binary and probabilistic theories of grammaticality. These judgements are gradient in nature, and so cannot be directly accommodated in a binary formal grammar. However, it is also not possible to simply reduce acceptability to probability. The acceptability of a sentence is not the same as the likelihood of its occurrence, which is, in part, determined by factors like sentence length and lexical frequency. In this paper, we present the results of a set of large-scale experiments using crowd-sourced acceptability judgments that demonstrate gradience to be a pervasive feature in acceptability judgments. We then show how one can predict acceptability judgments on the basis of probability by augmenting probabilistic language models with an acceptability measure. This is a function that normalizes probability values to eliminate the confounding factors of length and lexical frequency. We describe a sequence of modeling experiments with unsupervised language models drawn from state-of-the-art machine learning methods in natural language processing. Several of these models achieve very encouraging levels of accuracy in the acceptability prediction task, as measured by the correlation between the acceptability measure scores and mean human acceptability values. We consider the relevance of these results to the debate on the nature of grammatical competence, and we argue that they support the view that linguistic knowledge can be intrinsically probabilistic.

A study on the optimum fast neutron flux for boron neutron capture therapy of deep-seated tumors.

PubMed

Rasouli, Fatemeh S; Masoudi, S Farhad

2015-02-01

High-energy neutrons, named fast neutrons which have a number of undesirable biological effects on tissue, are a challenging problem in beam designing for Boron Neutron Capture Therapy, BNCT. In spite of this fact, there is not a widely accepted criterion to guide the beam designer to determine the appropriate contribution of fast neutrons in the spectrum. Although a number of researchers have proposed a target value for the ratio of fast neutron flux to epithermal neutron flux, it can be shown that this criterion may not provide the optimum treatment condition. This simulation study deals with the determination of the optimum contribution of fast neutron flux in the beam for BNCT of deep-seated tumors. Since the dose due to these high-energy neutrons damages shallow tissues, delivered dose to skin is considered as a measure for determining the acceptability of the designed beam. To serve this purpose, various beam shaping assemblies that result in different contribution of fast neutron flux are designed. The performances of the neutron beams corresponding to such configurations are assessed in a simulated head phantom. It is shown that the previously used criterion, which suggests a limit value for the contribution of fast neutrons in beam, does not necessarily provide the optimum condition. Accordingly, it is important to specify other complementary limits considering the energy of fast neutrons. By analyzing various neutron spectra, two limits on fast neutron flux are proposed and their validity is investigated. The results show that considering these limits together with the widely accepted IAEA criteria makes it possible to have a more realistic assessment of sufficiency of the designed beam. Satisfying these criteria not only leads to reduction of delivered dose to skin, but also increases the advantage depth in tissue and delivered dose to tumor during the treatment time. The Monte Carlo Code, MCNP-X, is used to perform these simulations. Copyright © 2014 Elsevier Ltd. All rights reserved.

Results of recent microbicide and pre-exposure prophylaxis clinical trials have shown adherence to be a significant challenge with new HIV prevention technologies. As the vaginal ring containing dapivirine moves into two open label follow-on studies (HOPE/MTN-025 and DREAM) and other antiretroviral-based and multi-purpose prevention technology ring products advance through the development pipeline, there is a need for more accurate and reliable measures of adherence to microbicide ring products. We previously conducted a comprehensive landscape analysis to identify new technologies that could be applied to adherence measurement of vaginal rings containing antiretrovirals. To explore attitudes and perceptions towards the approaches that we identified, we conducted a survey of stakeholders with experience and expertise in microbicide and HIV prevention clinical trials. From May to July 2015 an electronic survey was distributed via email to 894 stakeholders; a total of 206 eligible individuals responded to at least one question and were included in the data analysis. Survey respondents were presented with various objective measures and asked about their perceived acceptability to trial participants, feasibility of implementation by study staff, usefulness for measuring adherence and ethical concerns. Methods that require no additional input from the participant and require no modifications to the existing ring product (i.e., measurement of residual drug or excipient, or a vaginal analyte that enters the ring) were viewed as being more acceptable to trial participants and more feasible to implement in the field. Respondents saw value in using objective measures to provide real-time feedback on adherence. However, approaches that involve unannounced home visits for sample collection or spot checks of ring use, which could provide significant value to adherence feedback efforts, were met with skepticism. Additional research on the acceptability of these methods to potential trial participants and trial staff is recommended. PMID:28708847

Technology acceptance perception for promotion of sustainable consumption.

PubMed

Biswas, Aindrila; Roy, Mousumi

2018-03-01

Economic growth in the past decades has resulted in change in consumption pattern and emergence of tech-savvy generation with unprecedented increase in the usage of social network technology. In this paper, the technology acceptance value gap adapted from the technology acceptance model has been applied as a tool supporting social network technology usage and subsequent promotion of sustainable consumption. The data generated through the use of structured questionnaires have been analyzed using structural equation modeling. The validity of the model and path estimates signifies the robustness of Technology Acceptance value gap in adjudicating the efficiency of social network technology usage in augmentation of sustainable consumption and awareness. The results indicate that subjective norm gap, ease-of-operation gap, and quality of green information gap have the most adversarial impact on social network technology usage. Eventually social networking technology usage has been identified as a significant antecedent of sustainable consumption.

When is it OK to be drunk? Situational and cultural variations in the acceptability of visible intoxication in the UK and Norway.

Research on norms regulating drunken behaviour has tended to focus on differences between different countries and cultures rather than variations within them. Here, we examine whether there are: (i) situation-specific differences in the acceptability of visible intoxication among students in the UK and Norway; (ii) whether there are situation-specific and overall differences in this regard between the two countries; and finally (iii) to what degree possible differences reflect individual characteristics such as use of alcohol, perceived harm of alcohol consumption, and broader value orientation. Students at one British (n=473) and one Norwegian (n=472) university responded to a survey including a battery of questions assessing the acceptability of visible intoxication in different situations, such as with friends, with work colleagues, with family members, and situations where children are present. Data were also collected regarding alcohol consumption, perceived harms of alcohol consumption, and value orientation. Analyses of covariance were performed to assess patterns in the acceptability of visible intoxication across different situations, and the relative contributions of country, alcohol consumption, perceived harm of alcohol consumption and human values. In both countries, visible intoxication was rated as most acceptable in situations involving friends and colleagues. Students from both countries rated visible intoxication least acceptable in situations where children are present. However, both overall, and in situations where children or family members are present, acceptability of visible intoxication scores were higher in the UK than Norway. These differences persisted after control for other variables. The study demonstrates large situational variation in acceptability of drunken behaviour, pointing to a fine-meshed set of norms regulating alcohol use and drunken behaviour within the two cultures, with the UK standing out as a more alcohol-liberal culture than Norway. Such differences underline how norms regulating drunken behaviour are culturally constituted. Copyright © 2015 Elsevier B.V. All rights reserved.

Geo-spatial aspects of acceptance of illegal hunting of large carnivores in Scandinavia.

2013-01-01

Human-carnivore conflicts are complex and are influenced by: the spatial distribution of the conflict species; the organisation and intensity of management measures such as zoning; historical experience with wildlife; land use patterns; and local cultural traditions. We have used a geographically stratified sampling of social values and attitudes to provide a novel perspective to the human - wildlife conflict. We have focused on acceptance by and disagreements between residents (measured as Potential Conflict Index; PCI) towards illegal hunting of four species of large carnivores (bear, lynx, wolf, wolverine). The study is based on surveys of residents in every municipality in Sweden and Norway who were asked their opinion on illegal hunting. Our results show how certain social values are associated with acceptance of poaching, and how these values differ geographically independent of carnivore abundance. Our approach differs from traditional survey designs, which are often biased towards urban areas. Although these traditional designs intend to be representative of a region (i.e. a random sample from a country), they tend to receive relatively few respondents from rural areas that experience the majority of conflict with carnivores. Acceptance of poaching differed significantly between Norway (12.7-15.7% of respondents) and Sweden (3.3-4.1% of respondents). We found the highest acceptance of illegal hunting in rural areas with free-ranging sheep and strong hunting traditions. Disagreements between residents (as measured by PCI) were highest in areas with intermediate population density. There was no correlation between carnivore density and either acceptance of illegal hunting or PCI. A strong positive correlation between acceptance of illegal hunting and PCI showed that areas with high acceptance of illegal hunting are areas with high potential conflict between people. Our results show that spatially-stratified surveys are required to reveal the large scale patterns in social dynamics of human-wildlife conflicts.

This systematic literature review collects and summarizes research on consumer acceptance and preferences for nutrition-modified and functional dairy products, to reconcile, and expand upon, the findings of previous studies. We find that female consumers show high acceptance for some functional dairy products, such as yogurt enriched with calcium, fiber and probiotics. Acceptance for functional dairy products increases among consumers with higher diet/health related knowledge, as well as with aging. General interest in health, food-neophobia and perceived self-efficacy seem also to contribute shaping the acceptance for functional dairy products. Furthermore, products with "natural" matches between carriers and ingredients have the highest level of acceptance among consumers. Last, we find that brand familiarity drives consumers with low interest in health to increase their acceptance and preference for health-enhanced dairy products, such as probiotic yogurts, or those with a general function claim.

Facts and values: on the acceptability of risks in children's sport using the example of rugby - a narrative review.

PubMed

Quarrie, Kenneth Lincoln; Brooks, John H M; Burger, Nicholas; Hume, Patria A; Jackson, Steve

2017-08-01

A clash of values has been identified between those who assert that:1. all childhood injuries, regardless of origin, are inherently undesirable and should be prevented and;2. those who believe that some measure of injury to children is an acceptable compromise for the physical benefits associated with physical activity and the development of abilities to appraise and deal with risks.A debate regarding whether the tackles and collisions permitted in schools' rugby represent acceptable risks, and what steps should be taken if they do not, exemplifies the issue.Questions regarding the magnitude of injury risks in sport are issues of fact and can be quantified via the results of injury surveillance studies. Risks are neither high nor low in isolation; they are relatively high or low with reference to other activities or across groups participating in an activity. Issues of the acceptability of a given degree of risk are value dependent. Research regarding perceptions of risk reveals wide variations in the degree of risk people view as acceptable. Factors impacting on risk perception include whether the risks are well known and understood, whether they are 'dread' risks and the degree to which people undertake the risks voluntarily and feel they have control over them.Based on the evidence currently available, the risks to children playing rugby do not appear to be inordinately high compared with those in a range of other childhood sports and activities, but better comparative information is urgently needed. Further evidence, however, should not necessarily be expected to result in the resolution of acceptable risk debates-pre-existing values shape our perspectives on whether new evidence is relevant, valid and reliable. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Acceptance and valued living as critical appraisal and coping strengths for caregivers dealing with terminal illness and bereavement.

PubMed

Davis, Esther L; Deane, Frank P; Lyons, Geoffrey C B

2015-04-01

Informal caregivers of palliative care patients play an essential role in the coordination of care for patients during their final phases of life. However, undertaking a caregiving role can have enduring psychological consequences for caregivers and interfere with functioning. Studies have investigated a variety of factors associated with individual differences in caregiver psychosocial outcomes, but little is known about their relative impact, and there is a need for guiding models to support research in this area. A review of the literature was conducted on factors influencing the psychological distress and grief of caregivers. Drawing from acceptance and commitment therapy (ACT) and Stroebe and colleagues' integrative risk factor framework, we developed a process model to describe individual differences in caregiver psychological distress and grief. The model presents caregiver psychological distress and grief as functions of death attitudes and communication about death and dying, mediated by acceptance and valued living from an ACT perspective. An outline of the empirical and theoretical underpinnings for each component in the model is provided. SIGNIFICANT OF RESULTS: The presented model is an inherently strengths-based model that is concordant with acceptance- and values- (ACT) based interventions to facilitate coping in caregivers.

The purpose of this study was to provide quantitative evidence of patients' tolerance for therapeutic risks associated with psoriasis treatments that could offer psoriasis improvements beyond the PASI 75 benchmark. We used a discrete-choice experiment in which respondents chose between competing psoriasis treatments characterized by benefits (i.e. reduced plaque severity, reduced plaque area), risks (i.e. 10-year risk of tuberculosis, 10-year risk of death from infection), and treatment regimen. We analyzed choice data using random-parameters logit models for psoriasis affecting the body, face, or hands. Of 927 eligible members of the National Psoriasis Foundation who completed the survey, 28% were unwilling to accept any greater risk of treatment-related infection mortality. Among the remaining 72%, respondents were willing to accept higher risks of infection-related mortality associated with treatment to completely remove plaques covering only 1% of the body, compared to reducing lesions from 10 to 1% of the affected area. This finding was more pronounced for lesions on the face. Most patients placed greater value on eliminating even very small plaques compared to avoiding treatment-related risks. The perceived importance of complete versus near-complete clearance was stronger than previously documented.

Determination and evaluation of acceptable force limits in single-digit tasks.

PubMed

Nussbaum, Maury A; Johnson, Hope

2002-01-01

Acceptable limits derived from psychophysical methodologies have been proposed, measured, and employed in a range of applications. There is little existing work, however, on such limits for single-digit exertions and relatively limited evidence on several fundamental issues related to data collection and processing of a sequence of self-regulated exertion levels. An experimental study was conducted using 14 male and 10 female participants (age range 18-31 years) from whom maximal voluntary exertions and maximal acceptable limits (MALs) were obtained using the index finger and thumb. Moderate to high levels of consistency were found for both measures between sessions separated by one day. Single MAL values, determined from a time series of exertions, were equivalent across three divergent processing methods and between values obtained from 5- and 25-min samples. A critical interpretation of these and earlier results supports continued use of acceptable limits but also suggests that they should be used with some caution and not equated with safe limits. This research can be applied toward future development of exertion limits based on perceived acceptability.

Introduction This randomized pilot trial evaluated two training modalities for first-line, evidence-based pediatric obesity services (screening and goal-setting) among nursing students. Method Participants (N=63) were randomized to Live Interactive Training (Live) or Web-facilitated Self-study Training (Web). Pre-training, post-training, and one-month follow-up assessments evaluated training feasibility, acceptability, and impact (knowledge, and skill via simulation). Moderator (previous experience) and predictor (content engagement) analyses were conducted. Results Nearly-all (98%) participants completed assessments. Both trainings were acceptable, with higher ratings for Live and participants with previous experience (p’s<.05). Knowledge and skill improved from pre-training to post-training and follow-up in both conditions (p’s<.001). Live demonstrated greater content engagement (p’s<.01). Conclusions The training package was feasible, acceptable, and efficacious among nursing students. Given that Live had higher acceptability and engagement, and online training offers greater scalability, integrating interactive Live components within Web-based training may optimize outcomes, which may enhance practitioners’ delivery of pediatric obesity services.

Evaluation of the intake of radon through skin from thermal water

Sakoda, Akihiro; Ishimori, Yuu; Tschiersch, Jochen

2016-01-01

The biokinetics of radon in the body has previously been studied with the assumption that its absorption through the skin is negligibly small. This assumption would be acceptable except in specific situations, such as bathing in a radon hot spring where the radon concentration in thermal water is far higher than that in air. The present study focused on such a situation in order to better understand the biokinetics of radon. To mathematically express the entry of radon through the skin into the body, we first modified the latest sophisticated biokinetic model for noble gases. Values of an important parameter for the model—the skin permeability coefficient K (m s−1)—were derived using data from previous human studies. The analysis of such empirical data, which corresponded to radon concentrations in the air exhaled by subjects during and following bathing in radon-rich thermal water, revealed that the estimated K values had a log-normal distribution. The validity of the K values and the characteristics of the present model are then discussed. Furthermore, the impact of the intake of radon or its progeny via inhalation or skin absorption on radiation dose was also assessed for possible exposure scenarios in a radon hot spring. It was concluded that, depending on the radon concentration in thermal water, there might be situations in which the dose contribution resulting from skin absorption of radon is comparable to that resulting from inhalation of radon and its progeny. This conclusion can also apply to other therapeutic situations (e.g. staying in the pool for a longer period). PMID:26983980

Eating disorders have been described as possible 'culture-bound syndromes', with roots in Western cultural values and conflicts. They may, in fact, be more prevalent within various non-Western cultural groups than previously recognised, as Western values become more widely accepted. Cross-cultural experiences suggest that cultural change itself may be associated with increased vulnerability to eating disorders, especially when Western values about physical aesthetics are involved. to assess the eating attitudes and behaviours among adolescents in the urban ethnic city, Mumbai, a survey was conducted amongst 451 college students. the study, based in four junior colleges, comprised 451 subjects who completed a semi-structured questionnaire, a 26-item Eating Attitudes Test (EAT-26) and the Personal Assessment Inventory (IPAT). the results revealed faulty eating habits in 13.3% of the subjects. A statistically significant proportion perceived them-selves to have problems with eating, substance use, dieting and exercise practices, resorting to extreme measures to achieve weight loss. A high rate of faulty eating habits was observed in males. Higher scores on depression and suicidal ideation were reported in the population with faulty eating habits. a significant percentage of college-going populations in urban settings probably have faulty eating habits.

In many European countries, the last decade has been marked by an increasing debate about the acceptability and regulation of euthanasia and other end-of-life decisions in medical practice. Growing public sensibility to a 'right to die' for terminally ill patients has been one of the main constituents of these debates. Within this context, we sought to describe and compare acceptance of euthanasia among the general public in 33 European countries. We used the European Values Study data of 1999-2000 with a total of 41125 respondents (63% response rate) in 33 European countries. The main outcome measure concerned the acceptance of euthanasia (defined as 'terminating the life of the incurably sick', rated on a scale from 1 to 10). Results showed that the acceptance of euthanasia tended to be high in some countries (e.g. the Netherlands, Denmark, France, Sweden), while a markedly low acceptance was found in others (e.g. Romania, Malta and Turkey). A multivariate ordinal regression showed that weaker religious belief was the most important factor associated with a higher acceptance; however, there were also socio-demographic differences: younger cohorts, people from non-manual social classes, and people with a higher educational level tended to have a higher acceptance of euthanasia. While religious belief, socio-demographic factors, and also moral values (i.e. the belief in the right to self-determination) could largely explain the differences between countries, our findings suggest that perceptions regarding euthanasia are probably also influenced by national traditions and history (e.g. Germany). Thus, we demonstrated clear cross-national differences with regard to the acceptance of euthanasia, which can serve as an important basis for further debate and research in the specific countries.

Relations of children's proactive and reactive assertiveness to peer acceptance: moderating effects of social interest.

Lee, Han-Jong

2014-06-01

Previous studies on the social outcome of assertiveness reported mixed findings, failing to support the assumption that assertiveness promotes peer acceptance. In an attempt to provide explanations for the inconsistencies in prior findings, this study proposed making a distinction between proactive and reactive assertiveness and examined the moderating effects of social interest. A total of 441 fifth and sixth graders (232 boys, 209 girls; M age = 10.6 yr., SD = 0.6) participated in the study. Results indicated that proactive assertiveness was positively related to peer acceptance regardless of social interest. By contrast, reactive assertiveness was positively related to peer acceptance but only when social interest is high. When social interest is low, it was negatively associated with peer acceptance.

The documentation of the nursing process is an important but often neglected part of clinical documentation. Paper-based systems have been introduced to support nursing process documentation. Frequently, however, problems such as low quality of documentation are reported. It is unclear whether computer-based documentation systems can reduce these problems and which factors influence their acceptance by users. We introduced a computer-based nursing documentation system on four wards of the University Hospitals of Heidelberg and systematically evaluated its preconditions and its effects in a pretest-posttest intervention study. For the analysis of user acceptance, we concentrated on subjective data drawn from questionnaires and interviews. A questionnaire was developed using items from published questionnaires and items that had to be developed for the special purpose of this study. The quantitative results point to two factors influencing the acceptance of a new computer-based documentation system: the previous acceptance of the nursing process and the previous amount of self-confidence when using computers. On one ward, the diverse acceptance scores heavily declined after the introduction of the nursing documentation system. Explorative qualitative analysis on this ward points to further success factors of computer-based nursing documentation systems. Our results can be used to assist the planning and introduction of computer-based nursing documentation systems. They demonstrate the importance of computer experience and acceptance of the nursing process on a ward but also point to other factors such as the fit between nursing workflow and the functionality of a nursing documentation system.

Social-emotional competence and early adolescents' peer acceptance in school: Examining the role of afternoon cortisol.

Oberle, Eva

2018-01-01

The present study investigated the role of afternoon cortisol in social-emotional competence and peer acceptance in early adolescence. To date, research on basal cortisol activity and social development in childhood and adolescence has predominately focused on understanding maladjustment and dysfunction in development. The degree to which basal cortisol is also involved in positive adjustment and social functioning remains largely unexplored. A total of 154 early adolescents (46% female; Mean age = 11.26; SD = .65) from diverse ethnic backgrounds provided self-reports of perspective taking, peer reports of acceptance by classmates, peer reports of prosocial behaviors, and saliva samples to assess basal cortisol. As expected and in alignment with previous research, afternoon cortisol, perspective taking, prosocial behaviors, and peer acceptance were all positively correlated. Path analyses followed by bootstrapping analyses revealed that the direct path from higher afternoon cortisol to higher levels of prosocial behavior was fully mediated by perspective taking skills. The direct path from higher afternoon cortisol to peer acceptance was fully mediated by perspective taking skills and prosocial behavior. The findings are discussed within the broader context of previous research on cortisol and social adjustment in childhood and early adolescence. The practical relevance of the findings is considered.

The evil of banality: When choosing between the mundane feels like choosing between the worst.

Our most important decisions often provoke the greatest anxiety, whether we seek the better of two prizes or the lesser of two evils. Yet many of our choices are more mundane, such as selecting from a slate of mediocre but acceptable restaurants. Previous research suggests that choices of decreasing value should provoke decreasing anxiety. Here we show that this is not the case. Across three behavioral studies and one fMRI study, we find that anxiety and its neural correlates demonstrate a U-shaped function of choice set value, greatest when choosing between both the highest value and lowest value sets. Intermediate (moderate-value) choice sets provoke the least anxiety, even when they are just as difficult to select between as the choice sets at the two extremes. We show that these counterintuitive findings are accounted for by decision makers perceiving low-value items as aversive (i.e., negatively motivationally salient) rather than simply unrewarding. Importantly, though, neural signatures of these anxious reactions only appear when participants are required to choose one item from a set and not when simply appraising that set's overall value. Decision makers thus experience anxiety from competing avoidance motivations when forced to select among low-value options, comparable to the competing approach motivations they experience when choosing between high-value items. We further show that a common method of measuring subjective values (willingness to pay) can inadvertently censor a portion of this quadratic pattern, creating the misperception that anxiety simply increases linearly with set value. Collectively, these findings reveal the surprising costs of seemingly banal decisions. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The efficacy and safety of combination therapy (repaglinide plus pioglitazone) was compared to repaglinide or pioglitazone in 24-week treatment of type 2 diabetes. This randomized, multicenter, open-label, parallel-group study enrolled 246 adults (age 24-85) who had shown inadequate response in previous sulfonylurea or metformin monotherapy (HbA(1c) > 7%). Prior therapy was withdrawn for 2 weeks, followed by randomization to repaglinide, pioglitazone, or repaglinide/pioglitazone. In the first 12 weeks of treatment, repaglinide doses were optimized, followed by 12 weeks of maintenance therapy. Pioglitazone dosage was fixed at 30 mg per day. Baseline HbA(1c) values were comparable (9.0% for repaglinide, 9.1% for pioglitazone, 9.3% for combination). Mean changes in HbA(1c) values at the end of treatment were -1.76% for repaglinide/pioglitazone, -0.18% for repaglinide, +0.32% for pioglitazone. Fasting plasma glucose reductions were -82 mg/dl for combination therapy, -34 mg/dl for repaglinide, -18 mg/dl for pioglitazone. Minor hypoglycemia occurred in 5% of patients for the combination, 8% for repaglinide, and 3% for pioglitazone. Weight gains for combination therapy were correlated to individual HbA(1c) reductions. In summary, for patients who had previously failed oral antidiabetic monotherapy, the combination repaglinide/pioglitazone had acceptable safety, with greater reductions of glycemic parameters than therapy using either agent alone.

A potential of about −0.8 (±0.2) V (at 1 M versus normal hydrogen electrode) for the reduction of nitric oxide (NO) to its one-electron reduced species, nitroxyl anion (3NO−) has been determined by a combination of quantum mechanical calculations, cyclic voltammetry measurements, and chemical reduction experiments. This value is in accord with some, but not the most commonly accepted, previous electrochemical measurements involving NO. Reduction of NO to 1NO− is highly unfavorable, with a predicted reduction potential of about −1.7 (±0.2) V at 1 M versus normal hydrogen electrode. These results represent a substantial revision of the derived and widely cited values of +0.39 V and −0.35 V for the NO/3NO− and NO/1NO− couples, respectively, and provide support for previous measurements obtained by electrochemical and photoelectrochemical means. With such highly negative reduction potentials, NO is inert to reduction compared with physiological events that reduce molecular oxygen to superoxide. From these reduction potentials, the pKa of 3NO− has been reevaluated as 11.6 (±3.4). Thus, nitroxyl exists almost exclusively in its protonated form, HNO, under physiological conditions. The singlet state of nitroxyl anion, 1NO−, is physiologically inaccessible. The significance of these potentials to physiological and pathophysiological processes involving NO and O2 under reductive conditions is discussed. PMID:12177417

Ultra-precise single-ion atomic mass measurements on deuterium and helium-3

2015-04-01

The former University of Washington Penning Trap Mass Spectrometer (UW-PTMS), now located at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany, was used in the decade before the move to determine new values for the deuteron atomic mass, M (2H+) = 2.013 553 212 745(40) u, and the deuterium atomic mass, M (2H) = 2.014 101 778 052(40) u, both of which are now more than an order-of-magnitude more accurate than the previous best 1994-MIT measurements of these quantities. The new value for the deuteron’s mass can then be used with the accepted 2010-CODATA proton mass and the most recent 1999-measurement of the 2.2 MeV gamma-ray binding energy of the deuteron to refine the neutron’s mass to mn = 1.008 664 916 018(435) u which has about half the uncertainty relative to the value computed using that previous 1994-MIT deuterium measurement. As a result, further improvements of mn must now come from a more accurate determination of the wavelength of this gamma ray. In this same period of time, this spectrometer has also been used to determine new values for the helion atomic mass, M (3He2+) = 3.014 932 246 668(43) u, and the neutral helium-3 atomic mass, M (3He) = 3.016 029 321 675(43) u, which are both about 60 times more accurate than the 2006-SMILETRAP measurements, but disagree with the 4.4-times less-accurate 2015-Florida-State measurements by 0.76 nu. It is expected that these helium-3 results will be used in the future 3H/3He mass ratio (to be determined by the Heidelberg, Germany version of the old UW-PTMS) in order to generate a more accurate value for the tritium atomic mass.

Reassessment of True Core Collapse Differential Pressure Values for Filter Elements in Safety Critical Environments - 13076

Swain, Adam

2013-07-01

As the areas of application for diverse filter types increases, the mechanics and material sciences associated with the hardware and its relationship with more and more arduous process environments becomes critical to the successful and reliable operation of the filtration equipment. Where the filter is the last safe barrier between the process and the life environment, structural integrity and reliability is paramount in both the validation and the ethical acceptability of the designed equipment. Core collapse is a key factor influencing filter element selection, and is an extremely complex issue with a number of variables and failure mechanisms. It ismore » becoming clear that the theory behind core collapse calculations is not always supported with real tested data. In exploring this issue we have found that the calculation method is not always reflective of the true as tested collapse value, with the calculated values being typically in excess or even an order of magnitude higher than the tested values. The above claim is supported by a case study performed by the author, which disproves most of what was previously understood to be true. This paper also aims to explore the various failure mechanisms of different configurations of filter core, comparing calculated collapse values against real tested values, with a view to understanding a method of calculating their true collapse value. As the technology is advancing, and filter elements are being used in higher temperature, higher pressure, more radioactive and more chemically aggressive environments, confidence in core collapse values and data is crucial.

The “We Card” Program: Tobacco Industry “Youth Smoking Prevention” as Industry Self-Preservation

PubMed Central

Malone, Ruth E.

2010-01-01

The “We Card” program is the most ubiquitous tobacco industry “youth smoking prevention” program in the United States, and its retailer materials have been copied in other countries. The program's effectiveness has been questioned, but no previous studies have examined its development, goals, and uses from the tobacco industry's perspective. On the basis of our analysis of tobacco industry documents released under the 1998 Master Settlement Agreement, we concluded that the We Card program was undertaken for 2 primary purposes: to improve the tobacco industry's image and to reduce regulation and the enforcement of existing laws. Policymakers should be cautious about accepting industry self-regulation at face value, both because it redounds to the industry's benefit and because it is ineffective. PMID:20466965

Idiopathic Intracranial Hypertension in Children and Adolescents: An Update.

Cleves-Bayon, Catalina

2018-03-01

Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri syndrome (PTC) is a serious neurological disorder that can lead to irreversible visual loss. Predominantly a disorder affecting women in reproductive years, the pediatric population is not spared. In the past few years, the condition has been redefined, due to new accepted values for opening pressure in children and advances in neuroimaging. Emerging techniques in ophthalmology are being increasingly used to monitor disease in these patients. And, although the treatment tools have not changed in several years, important evidence for efficacy for acetazolamide finally came to light in recent years in the Idiopathic Intracranial Hypertension Treatment Trial (IIHTT). This review article provides an overview on recent advances in diagnosis, evaluation and treatment of IIH. © 2017 American Headache Society.

The 2009 pandemic of influenza A (H1N1) infection has alerted many governments to make preparedness plan to control the spread of influenza A (H1N1) infection. Vaccination for influenza is one of the most important primary preventative measures to reduce the disease burden. Our study aims to assess the willingness of nurses who work for the community nursing service (CNS) in Hong Kong on their acceptance of influenza A (H1N1) influenza vaccination. 401 questionnaires were posted from June 24, 2009 to June 30, 2009 to community nurses with 67% response rate. Results of the 267 respondents on their willingness to accept influenza A (H1N1) vaccine were analyzed. Twenty-seven percent of respondents were willing to accept influenza vaccination if vaccines were available. Having been vaccinated for seasonable influenza in the previous 12 months were significantly independently associated with their willingness to accept influenza A (H1N1) vaccination (OR = 4.03; 95% CI: 2.03-7.98). Similar to previous findings conducted in hospital healthcare workers and nurses, we confirmed that the willingness of community nurses to accept influenza A (H1N1) vaccination is low. Future studies that evaluate interventions to address nurses' specific concerns or interventions that aim to raise the awareness among nurses on the importance of influenza A (H1N1) vaccination to protect vulnerable patient populations is needed.

Boring in response to bark and phloem extracts from North American trees does not explain host acceptance behavior of Orthotomicus erosus (Coleoptera: Scolytidae).

PubMed

Walter, Abigail J; Kells, Stephen A; Venette, Robert C; Seybold, Steven J

2010-04-01

When invasive herbivorous insects encounter novel plant species, they must determine whether the novel plants are hosts. The Mediterranean pine engraver, Orthotomicus erosus (Wollaston), an exotic bark beetle poised to expand its range in North America, accepts hosts after contacting the bark. To test the hypothesis that O. erosus accepts hosts on the basis of gustatory cues, we prepared bark and phloem extracts from logs of four North American tree species that we had used in previous host acceptance experiments. Water, methanol, and hexane extracts of red pine, tamarack, balsam fir, and paper birch were presented alone and in combination on a neutral filter paper substrate in a section of a plastic drinking straw. Boring behavior in response to the three-extract combinations differed from the pattern of acceptance previously observed among species when the beetles were in contact with the bark surface. Only the aqueous extracts of tamarack, Larix laricina, increased the initiation and the extent of boring by O. erosus on the filter paper substrate. We conclude that the effects of extracted chemicals do not match the behavior of the beetles observed when penetrating excised bark and phloem discs, indicating that host selection by O. erosus may not be predictable from bark and phloem chemistry alone. Instead, host acceptance may be determined by nongustatory stimuli or by a combination of stimuli including gustatory and nongustatory cues.

Emotional and rational disease acceptance in patients with depression and alcohol addiction.

2008-01-21

The concept of a rational respectively emotional acceptance of disease is highly valued in the treatment of patients with depression or addiction. Due to the importance of this concept for the long-term course of disease, there is a strong interest to develop a tool to identify the levels and factors of acceptance. We thus intended to test an instrument designed to assess the level of positive psychological wellbeing and coping, particularly emotional disease acceptance and life satisfaction In an anonymous cross-sectional survey enrolling 115 patients (51% female, 49% male; mean age 47.6 +/- 10.0 years) with depression and/or alcohol addiction, the ERDA questionnaire was tested. Factor analysis of the 29-item construct (Cronbach's alpha = 0.933) revealed a 4-factor solution, which explained 59.4% of variance: (1) Positive Life Construction, Contentedness and Well-Being; (2) Conscious Dealing with Illness; (3) Rejection of an Irrational Dealing with Disease; (4) Disease Acceptance. Two factors could be ascribed to a rational, and two to an emotional acceptance. All factors correlated negatively with Depression and Escape, while several aspects of Life Satisfaction" (i.e. myself, overall life, where I live, and future prospects) correlated positively. The highest factor scores were found for the rational acceptance styles (i.e. Conscious Dealing with Illness; Disease Acceptance). Emotional acceptance styles were not valued in a state of depression. Escape from illness was the strongest predictor for several acceptance aspects, while life satisfaction was the most relevant predictor for "Positive Life Construction, Contentedness and Well-Being". The ERDA questionnaire was found to be a reliable and valid assessment of disease acceptance strategies in patients with depressive disorders and drug abuses. The results indicate the preferential use of rational acceptance styles even in depression. Disease acceptance should not be regarded as a coping style with an attitude of fatalistic resignation, but as a complex and active process of dealing with a chronic disease. One may assume that an emotional acceptance of disease will result in a therapeutic coping process associated with higher level of life satisfaction and overall quality of life.

Quality characteristics of fried lamb nuggets from low-value meat cuts: Effect of formulation and freezing storage.

PubMed

Medina, Milagros; Antequera, Teresa; Ruiz, Jorge; Jiménez-Martín, Estefanía; Pérez-Palacios, Trinidad

2015-10-01

This study revealed the possibility of manufacturing prefried lamb nuggets from low-value cuts (flank) and evaluated the effect of formulation (50:50 vs. 20:80 of leg/flank cuts) and freezing (-20 ℃ for two months) on different quality parameters. Frying process produced a decrease of water content, an increase in lipid oxidation indicators, and an intense browning of nuggets surface. The use of flank up to a 75% of the total meat in the formula led to higher fat contents and higher polyunsaturated fatty acid proportions in fried nuggets. This made them more prone to get oxidized during the freezing storage and subsequent final frying. Nuggets with a higher proportion of flank also showed lower shear force values. However, nuggets with both formulations showed similar sensory acceptance. Freezing storage of lamb meat nuggets for two months increased the levels of lipid oxidation indicators, but again not to a level high enough to influence the sensory perception by consumers. So that, frozen nuggets from both formulations showed similar consumer acceptance to freshly produced ones with quite good scores (3.46-3.86 out of 5). Thus, low-value lamb cuts are suitable for being processed into highly acceptable prefried frozen lamb nuggets, which constitutes an opportunity for adding value to the whole lamb value chain. © The Author(s) 2014.

Contingent valuation and pharmacists' acceptable levels of compensation for medication therapy management services.

Wang, Junling; Hong, Song Hee

2015-01-01

Pharmacists' acceptable level of compensation for medication therapy management (MTM) services needs to be determined using various economic evaluation techniques. Using contingent valuation method, determine pharmacists' acceptable levels of compensation for MTM services. A mailing survey was used to elicit Tennessee (U.S.) pharmacists' acceptable levels of compensation for a 30-minute MTM session for a new patient with 2 medical conditions, 8 medications, and an annual drug cost of $2000. Three versions of a series of double-bounded, closed-ended, binary discrete choice questions were asked of pharmacists for their willingness to accept (WTA) for an original monetary value ($30, $60, or $90) and then follow-up higher or lower value depending on their responses to the original value. A Kaplan-Meier approach was taken to analyze pharmacists' WTA, and Cox's proportional hazards model was used to examine the effects of pharmacist characteristics on their WTA. Three hundred and forty-eight pharmacists responded to the survey. Pharmacists' WTA for the given MTM session had a mean of $63.31 and median of $60. The proportions of pharmacists willing to accept $30, $60, and $90 for the given MTM session were 30.61%, 85.19%, and 91.01%, respectively. Pharmacists' characteristics had statistically significant association with their WTA rates. Pharmacists' WTA for the given MTM session is higher than current Medicare MTM programs' compensation levels of $15-$50 and patients' willingness to pay of less than $40. Besides advocating for higher MTM compensation levels by third-party payers, pharmacists also may need to charge patients to reach sufficient compensation levels for MTM services.

To determine the visual 50:50% acceptability thresholds for lightness, chroma and hue for dental ceramics using CIEDE2000(K(L):K(C):K(H)) formula, and to evaluate the formula performance using different parametric factors. A 30-observer panel evaluated three subsets of ceramic samples: lightness subset (|ΔL'/ΔE(00)| ≥ 0.9), chroma subset (|ΔC'/ΔE(00)| ≥ 0.9) and hue subset (|ΔH'/ΔE(00)| ≥ 0.9). A Takagi-Sugeno-Kang Fuzzy Approximation was used as fitting procedure, and the 50:50% acceptability thresholds were calculated. A t-test was used in statistical analysis of the thresholds values. The performance of the CIEDE2000(1:1:1) and CIEDE2000(2:1:1) colour difference formulas against visual results was tested using PF/3 performance factor. The 50:50% CIEDE2000 acceptability thresholds were ΔL' = 2.92 (95% CI 1.22-4.96; r(2) = 0.76), ΔC' = 2.52 (95% CI 1.31-4.19; r(2) = 0.71) and ΔH' = 1.90 (95% CI 1.63-2.15; r(2) = 0.88). The 50:50% acceptability threshold for colour difference (ΔE') for CIEDE2000(1:1:1) was 1.87, whilst corresponding value for CIEDE2000(2:1:1) was 1.78. The PF/3 values were 139.86 for CIEDE2000(1:1:1), and 132.31 for CIEDE2000(2:1:1). There was a statistically significant difference amongst CIEDE2000 50:50% acceptability thresholds for lightness, chroma and hue differences for dental ceramics.

2012-01-01

Background Pharmacists' acceptable level of compensation for medication therapy management (MTM) services needs to be determined using various economic evaluation techniques. Objectives Using contingent valuation method, determine pharmacists' acceptable levels of compensation for MTM services. Methods A mailing survey was used to elicit Tennessee (US) pharmacists' acceptable levels of compensation for a 30-minute MTM session for a new patient with 2 medical conditions, 8 medications, and an annual drug cost of $2,000. Three versions of a series of double-bounded, closed-ended, binary discrete choice questions were asked of pharmacists for their willingness-to-accept (WTA) for an original monetary value ($30, $60, or $90) and then follow-up higher or lower value depending on their responses to the original value. A Kaplan-Meier approach was taken to analyze pharmacists' WTA, and Cox's proportional hazards model was used to examine the effects of pharmacist characteristics on their WTA. Results Three hundred and forty-eight pharmacists responded to the survey. Pharmacists' WTA for the given MTM session had a mean of $63.31 and median of $60. The proportions of pharmacists willing to accept $30, $60, and $90 for the given MTM session were 30.61%, 85.19%, and 91.01%, respectively. Pharmacists' characteristics had statistically significant association with their WTA rates. Conclusions Pharmacists' WTA for the given MTM session is higher than current Medicare MTM programs' compensation levels of $15 to $50 and patients' willingness-to-pay of less than $40. Besides advocating for higher MTM compensation levels by third-party payers, pharmacists also may need to charge patients to reach sufficient compensation levels for MTM services. PMID:22436583

Beany and grassy flavors in raw edible bean flours reduce consumer acceptability of bean-based baked products. In order to improve consumer acceptability, beans may be further processed by cooking and germination. However, these operations drive up the cost of end-products. Therefore, it is necessary to develop formulations, using raw edible bean flours that have acceptable sensory attributes. In this study, cooked, germinated, and germinated/steam-blanched (GSB) pinto bean flours were used to make gluten-free cookies, and their sensory characteristics evaluated to determine how their consumer acceptability scores compared. Taste panelists (31) graded cookies made from raw pinto beans with an overall value of 6 on a 9-point hedonic scale ( p  < .05). This rating was not significantly different from cookies formulated with germinated and GSB flours. Therefore, gluten-free cookies can be made using raw pinto bean flours at a 40% inclusion level, with similar sensory characteristics as those prepared with flours treated by cooking and germination. Instrumental measurement of cookie hardness and color showed no significant difference in hardness, but significant differences in color. The germinated bean flour produced cookies with a significantly lower L* value and significantly higher a*, b*, Chroma and hue values compared to the other treatments. There was no significant difference in the cookie spread ratio. Proximate composition, water absorption index (WAI), water solubility index (WSI) and gelatinization properties of the flour treatments were characterized.

Henry Cavendish (1731-1810): hydrogen, carbon dioxide, water, and weighing the world.

West, John B

Henry Cavendish (1731-1810) was an outstanding chemist and physicist. Although he was not a major figure in the history of respiratory physiology he made important discoveries concerning hydrogen, carbon dioxide, atmospheric air, and water. Hydrogen had been prepared earlier by Boyle but its properties had not been recognized; Cavendish described these in detail, including the density of the gas. Carbon dioxide had also previously been studied by Black, but Cavendish clarified its properties and measured its density. He was the first person to accurately analyze atmospheric air and reported an oxygen concentration very close to the currently accepted value. When he removed all the oxygen and nitrogen from an air sample, he found that there was a residual portion of about 0.8% that he could not characterize. Later this was shown to be argon. He produced large amounts of water by burning hydrogen in oxygen and recognized that these were its only constituents. Cavendish also worked on electricity and heat. However, his main contribution outside chemistry was an audacious experiment to measure the density of the earth, which he referred to as "weighing the world." This involved determining the gravitational attraction between lead spheres in a specially constructed building. Although this was a simple experiment in principle, there were numerous complexities that he overcame with meticulous attention to experimental details. His result was very close to the modern accepted value. The Cavendish Experiment, as it is called, assures his place in the history of science. Copyright © 2014 the American Physiological Society.

We report on astrometric observations of H2O masers around the red supergiant VY Canis Majoris carried out with VLBI Exploration of Radio Astrometry (VERA). Based on astrometric monitoring for 13 months, we successfully measured a trigonometric parallax of 0.88±0.08 mas, corresponding to a distance of 1.14+0.11-0.09kpc. This is the most accurate determined distance to VY CMa and the first one based on an annual parallax measurement. The luminosity of VY CMa has been overestimated due to a previously accepted distance. With our result, we re-estimated the luminosity of VY CMa to be (3±0.5) × 105Lodot using the bolometric flux integrated over optical and IR wavelengths. This improved luminosity value makes the location of VY CMa on the Hertzsprung-Russell (HR) diagram much closer to the theoretically allowable zone (i.e. the left side of the Hayashi track) than previous ones, though the uncertainty in the effective temperature of the stellar surface still does not permit us to make a final conclusion.

A neural network based reputation bootstrapping approach for service selection

Wu, Quanwang; Zhu, Qingsheng; Li, Peng

2015-10-01

With the concept of service-oriented computing becoming widely accepted in enterprise application integration, more and more computing resources are encapsulated as services and published online. Reputation mechanism has been studied to establish trust on prior unknown services. One of the limitations of current reputation mechanisms is that they cannot assess the reputation of newly deployed services as no record of their previous behaviours exists. Most of the current bootstrapping approaches merely assign default reputation values to newcomers. However, by this kind of methods, either newcomers or existing services will be favoured. In this paper, we present a novel reputation bootstrapping approach, where correlations between features and performance of existing services are learned through an artificial neural network (ANN) and they are then generalised to establish a tentative reputation when evaluating new and unknown services. Reputations of services published previously by the same provider are also incorporated for reputation bootstrapping if available. The proposed reputation bootstrapping approach is seamlessly embedded into an existing reputation model and implemented in the extended service-oriented architecture. Empirical studies of the proposed approach are shown at last.

A practical approach to determination of laboratory GC-MS limits of detection.

Determination of limit of detection (LOD) values in a forensic laboratory serves a fundamental forensic requirement for assay performance. In addition to demonstrating assay capability, LOD values can also be used to fulfill certification requirements of a high-volume forensic drug laboratory. The LOD was defined as the lowest concentration of drug that the laboratory can detect in a specimen with forensic certainty at a minimum of 85% of the time. Overall batch acceptance criteria included acceptable quantitation of control materials (within 20% of target), acceptable chromatography (symmetry, peak integration, peak shape, peak, and baseline resolution), retention time within +/-1% of the extracted standard, and mass ion ratios within +/-20% of the extracted standard mass ion ratios. Individual specimen acceptance criteria were the same as the batch acceptance criteria excluding the quantitation requirement. Data were collected from all instruments on different runs. A minimum of ten data points was required for each certified instrument, and a minimum of 85% of data points was acceptable. Quantitation within +/-20% of the LOD concentration was not required, but acceptable mass ratios were required. Data points with poor chromatography (internal standard failed mass ratios; interference of the baseline, for example, shoulders; asymmetry; and baseline resolution) was omitted from the acceptable rate calculation. Data points with good chromatography with failed mass ion ratios were included in the acceptable rate calculation. With these criteria, we established the following LODs: 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid, 2 ng/mL; benzoylecgonine, 5 ng/mL; phencyclidine, 2.5 ng/mL; amphetamine, 150 ng/mL; methamphetamine, 100 ng/mL; codeine, 500 ng/mL; and morphine, 1000 ng/mL.

Quantification of uncertainty in machining operations for on-machine acceptance.

Claudet, Andre A.; Tran, Hy D.; Su, Jiann-Chemg

Manufactured parts are designed with acceptance tolerances, i.e. deviations from ideal design conditions, due to unavoidable errors in the manufacturing process. It is necessary to measure and evaluate the manufactured part, compared to the nominal design, to determine whether the part meets design specifications. The scope of this research project is dimensional acceptance of machined parts; specifically, parts machined using numerically controlled (NC, or also CNC for Computer Numerically Controlled) machines. In the design/build/accept cycle, the designer will specify both a nominal value, and an acceptable tolerance. As part of the typical design/build/accept business practice, it is required to verifymore » that the part did meet acceptable values prior to acceptance. Manufacturing cost must include not only raw materials and added labor, but also the cost of ensuring conformance to specifications. Ensuring conformance is a substantial portion of the cost of manufacturing. In this project, the costs of measurements were approximately 50% of the cost of the machined part. In production, cost of measurement would be smaller, but still a substantial proportion of manufacturing cost. The results of this research project will point to a science-based approach to reducing the cost of ensuring conformance to specifications. The approach that we take is to determine, a priori, how well a CNC machine can manufacture a particular geometry from stock. Based on the knowledge of the manufacturing process, we are then able to decide features which need further measurements from features which can be accepted 'as is' from the CNC. By calibration of the machine tool, and establishing a machining accuracy ratio, we can validate the ability of CNC to fabricate to a particular level of tolerance. This will eliminate the costs of checking for conformance for relatively large tolerances.« less

This study investigated the required coefficient of friction (RCOF) and the tangent of center of mass (COM)–center of pressure (COP) angle in the mediolateral (ML) and anteroposterior (AP) directions during turning at different walking speeds. Sixteen healthy young adults (8 males and 8 females) participated in this study. The participants were instructed to conduct trials of straight walking and 90° step and spin turns to the right at each of three self-selected speeds (slow, normal, and fast). The ML and AP directions during turning gait were defined using the orientation of the pelvis to construct a body-fixed reference frame. The RCOF values and COM–COP angle tangent in the ML direction during turning at weight acceptance phase were higher than those during straight walking, and those values increased with increasing walking speed. The ML component of the RCOF and COM–COP tangent values during weight acceptance for step turns were higher than those for spin turns. The mean centripetal force during turning tended to increase with an increase in walking speed and had a strong positive correlation with the RCOF values in the ML direction (R = 0.97 during the weight acceptance phase; R = 0.95 during the push-off phase). Therefore, turning, particularly step turn, is likely to cause lateral slip at weight acceptance because of the increased centripetal force compared with straight walking. Future work should test at-risk population and compare with the present results. PMID:28640853

A threshold method for immunological correlates of protection

PubMed Central

2013-01-01

Background Immunological correlates of protection are biological markers such as disease-specific antibodies which correlate with protection against disease and which are measurable with immunological assays. It is common in vaccine research and in setting immunization policy to rely on threshold values for the correlate where the accepted threshold differentiates between individuals who are considered to be protected against disease and those who are susceptible. Examples where thresholds are used include development of a new generation 13-valent pneumococcal conjugate vaccine which was required in clinical trials to meet accepted thresholds for the older 7-valent vaccine, and public health decision making on vaccination policy based on long-term maintenance of protective thresholds for Hepatitis A, rubella, measles, Japanese encephalitis and others. Despite widespread use of such thresholds in vaccine policy and research, few statistical approaches have been formally developed which specifically incorporate a threshold parameter in order to estimate the value of the protective threshold from data. Methods We propose a 3-parameter statistical model called the a:b model which incorporates parameters for a threshold and constant but different infection probabilities below and above the threshold estimated using profile likelihood or least squares methods. Evaluation of the estimated threshold can be performed by a significance test for the existence of a threshold using a modified likelihood ratio test which follows a chi-squared distribution with 3 degrees of freedom, and confidence intervals for the threshold can be obtained by bootstrapping. The model also permits assessment of relative risk of infection in patients achieving the threshold or not. Goodness-of-fit of the a:b model may be assessed using the Hosmer-Lemeshow approach. The model is applied to 15 datasets from published clinical trials on pertussis, respiratory syncytial virus and varicella. Results Highly significant thresholds with p-values less than 0.01 were found for 13 of the 15 datasets. Considerable variability was seen in the widths of confidence intervals. Relative risks indicated around 70% or better protection in 11 datasets and relevance of the estimated threshold to imply strong protection. Goodness-of-fit was generally acceptable. Conclusions The a:b model offers a formal statistical method of estimation of thresholds differentiating susceptible from protected individuals which has previously depended on putative statements based on visual inspection of data.

Peer acceptance among Chinese adolescents: the role of emotional empathy, cognitive empathy and gender.

PubMed

Huang, Heqing; Su, Yanjie

2014-10-01

Previous studies have found mixed results on the relationship between empathy and peer acceptance. Emotional and cognitive components of empathy were hypothesised to play different roles in peer acceptance, and the relationship between empathy and peer acceptance differed across genders. In this study, 375 Chinese adolescents completed self-report measures of emotional and cognitive empathy. They also provided peer nominations that allowed for the determination of social preference and social impact scores. The results showed that a boy's cognitive empathy positively correlated with the extent to which he was liked by his male classmates, whereas a girl's cognitive empathy positively correlated with her social impact among her female classmates. This study suggests that empathy does not affect peer acceptance among adolescents uniformly; instead, gender plays a determinative role in the dialectics between social acceptance and empathy. © 2014 International Union of Psychological Science.

Gerontechnology acceptance by elderly Hong Kong Chinese: a senior technology acceptance model (STAM).

Chen, Ke; Chan, Alan Hoi Shou

2014-01-01

The purpose of this study was to develop and test a senior technology acceptance model (STAM) aimed at understanding the acceptance of gerontechnology by older Hong Kong Chinese people. The proposed STAM extended previous technology acceptance models and theories by adding age-related health and ability characteristics of older people. The proposed STAM was empirically tested using a cross-sectional questionnaire survey with a sample of 1012 seniors aged 55 and over in Hong Kong. The result showed that STAM was strongly supported and could explain 68% of the variance in the use of gerontechnology. For older Hong Kong Chinese, individual attributes, which include age, gender, education, gerontechnology self-efficacy and anxiety, and health and ability characteristics, as well as facilitating conditions explicitly and directly affected technology acceptance. These were better predictors of gerontechnology usage behaviour (UB) than the conventionally used attitudinal factors (usefulness and ease of use).

How does trust affect acceptance of a nuclear power plant (NPP): A survey among people living with Qinshan NPP in China

PubMed Central

Feldman, Marcus W.

2017-01-01

It is difficult to know whether different dimensions of trust have different effects on local residents’ acceptance of nuclear power plants (NPPs). In previous research such trust has been considered as a single dimensional concept. This paper divides trust into goodwill trust and competence trust, and we explore the ways in which trust affects acceptance of NPPs through structural equation modeling. A survey of 491 people was conducted in Haiyan County, China, where the Qinshan nuclear power plant is located. We find that goodwill trust is significantly correlated with competence trust, and each can indirectly promote residents’ acceptance of NPPs but by different paths. Goodwill trust improves acceptance of NPPs by decreasing risk perception, while competence trust improves acceptance of NPPs by increasing benefit perception. However, the associations between goodwill trust and benefit perception, competence trust and risk perception, are not significant. PMID:29176852

2003-01-01

This study examines how wildlife value orientations, attitudes, and gender influence acceptance of lethal actions to control deer in Cuyahoga Valley National Park in Ohio. Data were collected from female and male residents (n = 659) in a nine-county area, the primary service area of the park. Females and males demonstrated significant differences in their wildlife value orientations, attitudes toward lethal deer control, beliefs about the outcome of lethal deer control, and perceived personal impacts of lethal deer control. Gender also acted as a moderator of the relationship between values, beliefs and attitudes. Results indicate that a focus on understanding differences between males and females is essential to public participation in decision making concerning this and similar issues.

Attenuating initial beliefs: increasing the acceptance of anthropogenic climate change information by reflecting on values.

2014-05-01

Anthropogenic climate change information tends to be interpreted against the backdrop of initial environmental beliefs, which can lead to some people being resistant toward the information. In this article (N = 88), we examined whether self-affirmation via reflection on personally important values could attenuate the impact of initial beliefs on the acceptance of anthropogenic climate change evidence. Our findings showed that initial beliefs about the human impact on ecological stability influenced the acceptance of information only among nonaffirmed participants. Self-affirmed participants who were initially resistant toward the information showed stronger beliefs in the existence of climate change risks and greater acknowledgment that individual efficacy has a role to play in reducing climate change risks than did their nonaffirmed counterparts. © 2013 Society for Risk Analysis.

SCIENTIFIC AND SOCIAL VALUE JUDGMENTS FOR ORPHAN DRUGS IN HEALTH TECHNOLOGY ASSESSMENT.

2016-01-01

We explore how broader aspects of a treatment's value and the impact of the condition on patients not captured by routine health technology assessment (HTA) methods using clinical and economic evidence, defined as "other considerations," may influence HTA processes in different settings. Countries included were England, Scotland, Sweden, and France. Data sources were the publicly available reports on HTA recommendations. Ten drugs with European Medicines Agency orphan designation and appraised in England were selected. Qualitative thematic analysis was used to systematically identify and code all "other considerations" based on a previously developed methodological framework, which also coded whether it was provided by stakeholders, and how it influenced the decision. A classification framework of scientific and social value judgments was developed and used throughout the study. A total of 125 "other considerations" were identified and grouped into ten subcategories based on the information provided. Eighteen to 100 percent of these, depending on the agency, were put forward as one of the main reasons for the final decision potentially contributing to accepting a higher incremental cost-effectiveness ratio or uncertain evidence. Some of these were nonquantified or nonelicited and pertained to the assessor's judgment. A taxonomy of these value judgments was created to be used in future cases. Results also contributed to better defining the determinants of social value and improving accountability for reasonableness. The systematic identification of the scientific and social value judgments enables to better understanding the dimensions of value, which can be used to improve their transparency and consistent use across decisions and settings.

Longitudinal associations among parental acceptance, familism values, and sibling intimacy in Mexican-origin families.

2015-06-01

Prospective associations among parent-adolescent acceptance and familism values in early and middle adolescence and sibling intimacy in late adolescence and young adulthood were assessed in 246 Mexican-origin families. Older sibling gender and sibling gender constellation were investigated as moderators of these associations. Sibling intimacy was stable over time and younger siblings with older sisters reported higher levels of sibling intimacy than those with older brothers. As predicted, stronger familism values were associated with greater sibling intimacy, but this link was evident only for older sisters and for girl-girl dyads. The links from mother- and father-acceptance to sibling intimacy also depended on the gender constellation of the sibling dyad: Higher levels of maternal warmth were associated with greater sibling intimacy for older sisters and girl-girl sibling pairs but higher levels of paternal warmth were linked to greater sibling intimacy only for older siblings in mixed-gender sibling dyads. Findings are consistent with prior research on the role of gender in family relationships but extend this work to encompass the effects of both parents' and siblings' gender, as well as the role of sociocultural values in parents' socialization influences. © 2015 Family Process Institute.

Applying value sensitive design (VSD) to wind turbines and wind parks: an exploration.

PubMed

Oosterlaken, Ilse

2015-04-01

Community acceptance still remains a challenge for wind energy projects. The most popular explanation for local opposition, the Not in My Backyard effect, has received fierce criticism in the past decade. Critics argue that opposition is not merely a matter of selfishness or ignorance, but that moral, ecological and aesthetic values play an important role. In order to better take such values into account, a more bottom-up, participatory decision process is usually proposed. Research on this topic focusses on either stakeholder motivations/attitudes, or their behavior during project implementation. This paper proposes a third research focus, namely the 'objects' which elicit certain behavioral responses and attitudes-the wind turbine and parks. More concretely, this paper explores Value Sensitive Design (VSD) as way to arrive at wind turbines and parks that better embed or reflect key values. After a critical discussion of the notion of acceptance versus acceptability and support, the paper discusses existing literature on ecology and aesthetics in relation to wind turbine/park design, which could serve as 'building blocks' of a more integral VSD approach of the topic. It also discusses the challenge of demarcating wind park projects as VSD projects. A further challenge is that VSD has been applied mainly at the level of technical artifacts, whereas wind parks can best be conceptualized as socio-technical system. This new application would therefore expand the current practice of VSD, and may as a consequence also lead to interesting new insights for the VSD community. The paper concludes that such an outcome-oriented approach of wind turbines and park is worth exploring further, as a supplement to rather than a replacement of the process-oriented approach that is promoted by the current literature on community acceptance of wind parks.

Two-body contributions to the effective mass in nuclear effective interactions

2018-04-01

Starting from general expressions of well-chosen symmetric nuclear matter quantities derived for both zero- and finite-range effective theories, we derive some universal relations between them. We first show that, independently of the range, the two-body contribution is enough to describe correctly the saturation mechanism but gives an effective mass value around m*/m ≃0.4 when the other properties of the saturation point are set near their generally accepted values. Then, we show that a more elaborated interaction (for instance, an effective two-body density-dependent term on top of the pure two-body term) is needed to reach the accepted value m*/m ≃0.7 -0.8 .

Validation of odor concentration from mechanical-biological treatment piles using static chamber and wind tunnel with different wind speed values.

PubMed

Szyłak-Szydłowski, Mirosław

2017-09-01

The basic principle of odor sampling from surface sources is based primarily on the amount of air obtained from a specific area of the ground, which acts as a source of malodorous compounds. Wind tunnels and flux chambers are often the only available, direct method of evaluating the odor fluxes from small area sources. There are currently no widely accepted chamber-based methods; thus, there is still a need for standardization of these methods to ensure accuracy and comparability. Previous research has established that there is a significant difference between the odor concentration values obtained using the Lindvall chamber and those obtained by a dynamic flow chamber. Thus, the present study compares sampling methods using a streaming chamber modeled on the Lindvall cover (using different wind speeds), a static chamber, and a direct sampling method without any screens. The volumes of chambers in the current work were similar, ~0.08 m 3 . This study was conducted at the mechanical-biological treatment plant in Poland. Samples were taken from a pile covered by the membrane. Measured odor concentration values were between 2 and 150 ou E /m 3 . Results of the study demonstrated that both chambers can be used interchangeably in the following conditions: odor concentration is below 60 ou E /m 3 , wind speed inside the Lindvall chamber is below 0.2 m/sec, and a flow value is below 0.011 m 3 /sec. Increasing the wind speed above the aforementioned value results in significant differences in the results obtained between those methods. In all experiments, the results of the concentration of odor in the samples using the static chamber were consistently higher than those from the samples measured in the Lindvall chamber. Lastly, the results of experiments were employed to determine a model function of the relationship between wind speed and odor concentration values. Several researchers wrote that there are no widely accepted chamber-based methods. Also, there is still a need for standardization to ensure full comparability of these methods. The present study compared the existing methods to improve the standardization of area source sampling. The practical usefulness of the results was proving that both examined chambers can be used interchangeably. Statistically similar results were achieved while odor concentration was below 60 ou E /m 3 and wind speed inside the Lindvall chamber was below 0.2 m/sec. Increasing wind speed over these values results in differences between these methods. A model function of relationship between wind speed and odor concentration value was determined.

SU-E-I-27: Establishing Target Exposure Index Values for Computed Radiography

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

Murphy, N; Tchou, P; Belcher, K

2014-06-01

Purpose: To develop a standard set of target exposure index (TEI) values to be applied to Agfa Computed Radiography (CR) readers in accordance with International Electrotechnical Committee 62494-1 (ed. 1.0). Methods: A large data cohort was collected from six USAF Medical Treatment Facilities that exclusively use Agfa CR Readers. Dose monitoring statistics were collected from each reader. The data was analyzed based on anatomic region, view, and processing speed class. The Agfa specific exposure metric, logarithmic mean (LGM), was converted to exposure index (EI) for each data set. The optimum TEI value was determined by minimizing the number of studiesmore » that fell outside the acceptable deviation index (DI) range of +/− 2 for phototimed techniques or a range of +/−3 for fixed techniques. An anthropomorphic radiographic phantom was used to corroborate the TEI recommendations. Images were acquired of several anatomic regions and views using standard techniques. The images were then evaluated by two radiologists as either acceptable or unacceptable. The acceptable image with the lowest exposure and EI value was compared to the recommended TEI values using a passing DI range. Results: Target EI values were determined for a comprehensive list of anatomic regions and views. Conclusion: Target EI values must be established on each CR unit in order to provide a positive feedback system for the technologist. This system will serve as a mechanism to prevent under or overexposures of patients. The TEI recommendations are a first attempt at a large scale process improvement with the goal of setting reasonable and standardized TEI values. The implementation and effectiveness of the recommended TEI values should be monitored and adjustments made as necessary.« less

This randomized pilot trial evaluated two training modalities for first-line, evidence-based pediatric obesity services (screening and goal setting) among nursing students. Participants (N = 63) were randomized to live interactive training or Web-facilitated self-study training. Pretraining, post-training, and 1-month follow-up assessments evaluated training feasibility, acceptability, and impact (knowledge and skill via simulation). Moderator (previous experience) and predictor (content engagement) analyses were conducted. Nearly all participants (98%) completed assessments. Both types of training were acceptable, with higher ratings for live training and participants with previous experience (ps < .05). Knowledge and skill improved from pretraining to post-training and follow-up in both conditions (ps < .001). Live training demonstrated greater content engagement (p < .01). The training package was feasible, acceptable, and efficacious among nursing students. Given that live training had higher acceptability and engagement and online training offers greater scalability, integrating interactive live training components within Web-based training may optimize outcomes, which may enhance practitioners' delivery of pediatric obesity services.

Saranya, R.; Varadarajan, R.

2018-04-01

In many inventory models uncertainty is due to fuzziness and fuzziness is the closed possible approach to reality. In this paper, we proposed a fuzzy inventory model with acceptable shortage which is completely backlogged. We fuzzily the carrying cost, backorder cost and ordering cost using Triangular and Trapezoidal fuzzy numbers to obtain the fuzzy total cost. The purpose of our study is to defuzzify the total profit function by Graded Mean Integration Value Method. Further a numerical example is also given to demonstrate the developed crisp and fuzzy models.

Arsenic tolerance of cyanobacterial strains with potential use in biotechnology.

PubMed

Ferrari, Susana G; Silva, Patricia G; González, Diana M; Navoni, Julio A; Silva, Humberto J

2013-01-01

The arsenic content of various water bodies in Argentina is higher than the acceptable levels for human and animal uses. Cyanobacteria are widely distributed in aquatic environments and can bioaccumulate arsenic (As). This study presents the response of indigenous cyanobacteria to As(III) and As(V), including the species Tolypothrix tenuis, Nostoc muscorum and Nostoc minutum, previously used with biotechnological purposes. As(III) resulted more toxic than As(V) in all cases, causing cell death in the range of 5-20 mg/l. T. tenuis growth was sensitive to As(V) with lethal inhibition at 625 mg/l, whereas the Noctoc species were stimulated. EC50 values found were 73.34 mg/l for N. muscorum and 989.3 mg/l for N. minutum. Batch cultures of N. minutum showed improvements in both growth parameters and photosynthetic pigment content in the presence of 1,000 mg/l As(V). Increases of 66.7%, 75.5%, 40% and 20.7% in cell productivity, chlorophyll a, total carotenoids and C-phycocyanin respectively were observed, reaching a bioaccumulated arsenic value of 37.4 ¼g/g at the stationary growth phase.

Is the Factor-of-2 Rule Broadly Applicable for Evaluating the Prediction Accuracy of Metal-Toxicity Models?

PubMed

Meyer, Joseph S; Traudt, Elizabeth M; Ranville, James F

2018-01-01

In aquatic toxicology, a toxicity-prediction model is generally deemed acceptable if its predicted median lethal concentrations (LC50 values) or median effect concentrations (EC50 values) are within a factor of 2 of their paired, observed LC50 or EC50 values. However, that rule of thumb is based on results from only two studies: multiple LC50 values for the fathead minnow (Pimephales promelas) exposed to Cu in one type of exposure water, and multiple EC50 values for Daphnia magna exposed to Zn in another type of exposure water. We tested whether the factor-of-2 rule of thumb also is supported in a different dataset in which D. magna were exposed separately to Cd, Cu, Ni, or Zn. Overall, the factor-of-2 rule of thumb appeared to be a good guide to evaluating the acceptability of a toxicity model's underprediction or overprediction of observed LC50 or EC50 values in these acute toxicity tests.

2014-02-01

This study examines accuracy and comparability of 4 trademarked acoustic analysis software packages (AASPs): Praat, WaveSurfer, TF32, and CSL by using synthesized and natural vowels. Features of AASPs are also described. Synthesized and natural vowels were analyzed using each of the AASP's default settings to secure 9 acoustic measures: fundamental frequency (F0), formant frequencies (F1-F4), and formant bandwidths (B1-B4). The discrepancy between the software measured values and the input values (synthesized, previously reported, and manual measurements) was used to assess comparability and accuracy. Basic AASP features are described. Results indicate that Praat, WaveSurfer, and TF32 generate accurate and comparable F0 and F1-F4 data for synthesized vowels and adult male natural vowels. Results varied by vowel for women and children, with some serious errors. Bandwidth measurements by AASPs were highly inaccurate as compared with manual measurements and published data on formant bandwidths. Values of F0 and F1-F4 are generally consistent and fairly accurate for adult vowels and for some child vowels using the default settings in Praat, WaveSurfer, and TF32. Manipulation of default settings yields improved output values in TF32 and CSL. Caution is recommended especially before accepting F1-F4 results for children and B1-B4 results for all speakers.

The socio-legal acceptance of new technologies: a close look at artificial insemination.

PubMed

Bernstein, Gaia

2002-10-01

Heated debates often surround the introduction of an important new technology into society, as exemplified by current controversies surrounding human cloning and privacy protection on the Internet. Underlying these controversies are disruptions to central socio-legal values caused by these new technologies. Whether new technologies will eventually be accepted by society is often contingent on the reaction of the legal system. This mandates the formulation of a conceptual framework for understanding and structuring the way the law should react in cases surrounding the adoption of new technologies. By using the case study of artificial insemination this Article develops the tools for structuring the legal role in the acceptance process of new technologies. The three-century controversy surrounding the innovation of artificial insemination results from the innovations' disruption of the socio-legal value of the family. Artificial Insemination--although invented in the eighteenth-century--was rarely used until the 1930s, and only legalized in the 1960s. Its application to surrogacy and its use by unmarried women extends the controversy into the twenty-first century. The case study demonstrates the nature of the relationship among the technological, social and legal acceptance processes of new technologies, and analyzes the legal acceptance debate. The conceptual framework produced is useful in understanding and structuring the legal role in current debates surrounding the introduction and acceptance of new technologies.

Evaluation of the intake of radon through skin from thermal water.

Sakoda, Akihiro; Ishimori, Yuu; Tschiersch, Jochen

2016-07-01

The biokinetics of radon in the body has previously been studied with the assumption that its absorption through the skin is negligibly small. This assumption would be acceptable except in specific situations, such as bathing in a radon hot spring where the radon concentration in thermal water is far higher than that in air. The present study focused on such a situation in order to better understand the biokinetics of radon. To mathematically express the entry of radon through the skin into the body, we first modified the latest sophisticated biokinetic model for noble gases. Values of an important parameter for the model-the skin permeability coefficient K (m s(-1))-were derived using data from previous human studies. The analysis of such empirical data, which corresponded to radon concentrations in the air exhaled by subjects during and following bathing in radon-rich thermal water, revealed that the estimated K values had a log-normal distribution. The validity of the K values and the characteristics of the present model are then discussed. Furthermore, the impact of the intake of radon or its progeny via inhalation or skin absorption on radiation dose was also assessed for possible exposure scenarios in a radon hot spring. It was concluded that, depending on the radon concentration in thermal water, there might be situations in which the dose contribution resulting from skin absorption of radon is comparable to that resulting from inhalation of radon and its progeny. This conclusion can also apply to other therapeutic situations (e.g. staying in the pool for a longer period). © The Author 2016.

Cornelissen, Evelyn; Mitton, Craig; Davidson, Alan; Reid, Colin; Hole, Rachelle; Visockas, Anne-Marie; Smith, Neale

2016-06-20

Purpose - Program budgeting and marginal analysis (PBMA) is a priority setting approach that assists decision makers with allocating resources. Previous PBMA work establishes its efficacy and indicates that contextual factors complicate priority setting, which can hamper PBMA effectiveness. The purpose of this paper is to gain qualitative insight into PBMA effectiveness. Design/methodology/approach - A Canadian case study of PBMA implementation. Data consist of decision-maker interviews pre (n=20), post year-1 (n=12) and post year-2 (n=9) of PBMA to examine perceptions of baseline priority setting practice vis-à-vis desired practice, and perceptions of PBMA usability and acceptability. Findings - Fit emerged as a key theme in determining PBMA effectiveness. Fit herein refers to being of suitable quality and form to meet the intended purposes and needs of the end-users, and includes desirability, acceptability, and usability dimensions. Results confirm decision-maker desire for rational approaches like PBMA. However, most participants indicated that the timing of the exercise and the form in which PBMA was applied were not well-suited for this case study. Participant acceptance of and buy-in to PBMA changed during the study: a leadership change, limited organizational commitment, and concerns with organizational capacity were key barriers to PBMA adoption and thereby effectiveness. Practical implications - These findings suggest that a potential way-forward includes adding a contextual readiness/capacity assessment stage to PBMA, recognizing organizational complexity, and considering incremental adoption of PBMA's approach. Originality/value - These insights help us to better understand and work with priority setting conditions to advance evidence-informed decision making.

To understand the opinion and behavior of a group of college students about the degree of privacy considered appropriate in several clinical settings and in which situations breach of confidentiality is admitted. An anonymous questionnaire about confidentiality in clinical settings was answered by 711 college students. The study had a transversal, descriptive, qualitative-quantitative design. We studied recognition of the ethical criteria for confidentiality limitation, and in which situations, common in adolescent morbidity, disclosure of this information is accepted. Data analysis used Epi-Info 6.04 and Microsoft Excel, 1997. The research was approved by PUCRS' IRB. The ideal situation for disclosing information was considered by 82% of the adolescents as the previous granting of authorization, which differs from other forms of breaching confidentiality. In cases of non-authorized disclosure, most of them admitted that it in case of suicidal ideation (85%), violence (84.2%), sexual abuse (81.7%), nervous anorexia (81.3%) and risk of life to third parties (72.3%). Half of them agree to it in HIV/AIDS (57.9%), drug abuse (51.7%) and STD (44.7%) situations; less than one third accept it in situations of pregnancy (33.6%), homosexuality (20.7%) and sexual activity (15.6%). Participants assigned different grades to the value of confidentiality in their health care, accepting that information may be disclosed to others when the patient authorizes it. The higher the risk to their integrity, the easier it was for them to admit non-authorized disclosure of information, however in aspects related to their sexuality disclosure is practically denied.

Residents' willingness-to-pay for attributes of rural health care facilities.

As today's rural hospitals have struggled with financial sustainability for the past 2 decades, it is critical to understand their value relative to alternatives, such as rural health clinics and private practices. To estimate the willingness-to-pay for specific attributes of rural health care facilities in rural Kentucky to determine which services and operational characteristics are most valued by rural residents. We fitted choice experiment data from 769 respondents in 10 rural Kentucky counties to a conditional logit model and used the results to estimate willingness-to-pay for attributes in several categories, including hours open, types of insurance accepted, and availability of health care professionals and specialized care. Acceptance of Medicaid/Medicare with use of a sliding fee scale versus acceptance of only private insurance was the most valued attribute. Presence of full diagnostic services, an emergency room, and 24-hour/7-day-per-week access were also highly valued. Conversely, the presence of specialized care, such as physical therapy, cancer care, or dialysis, was not valued. In total, respondents were willing to pay $225 more annually to support a hospital relative to a rural health clinic. Rural Kentuckians value the services, convenience, and security that rural hospitals offer, though they are not willing to pay more for specialized care that may be available in larger medical treatment centers. The results also inform which attributes might be added to existing rural health facilities to make them more valuable to local residents. © 2014 National Rural Health Association.

We developed and validated an interinstrument comparison method for automatic hematology analyzers based on the 99th percentile coefficient of variation (CV) cutoff of daily means and validated in both patient samples and quality control (QC) materials. A total of 120 patient samples were obtained over 6 months. Data from the first 3 months were used to determine 99th percentile CV cutoff values, and data obtained in the last 3 months were used to calculate acceptable ranges and rejection rates. Identical analyses were also performed using QC materials. Two instrument comparisons were also performed, and the most appropriate allowable total error (ATE) values were determined. The rejection rates based on the 99th percentile cutoff values were within 10.00% and 9.30% for the patient samples and QC materials, respectively. The acceptable ranges of QC materials based on the currently used method were wider than those calculated from the 99th percentile CV cutoff values in most items. In two-instrument comparisons, 34.8% of all comparisons failed, and 87.0% of failed comparisons were successful when 4 SD was applied as an ATE value instead of 3 SD. The 99th percentile CV cutoff value-derived daily acceptable ranges can be used as a real-time interinstrument comparison method in both patient samples and QC materials. Applying 4 SD as an ATE value can significantly reduce unnecessarily followed recalibration in the leukocyte differential counts, reticulocytes, and mean corpuscular volume.

Karimnagar District has consistently achieved highest rates of no-scalpel vasectomy (NSV) in the past decade when compared to state and national rates. This study was conducted to elucidate the underlying causes for higher acceptance of NSV in the district. A community-based, case control study was conducted. Sampling techniques used were purposive and simple random sampling. A semi-structured questionnaire was used to evaluate the socio-demographic, family characteristics, contraceptive history and predictors of contraceptive choice in 116 NSV acceptors and 120 other contraceptive users (OCUs). Postoperative complications and experiences were ascertained in NSV acceptors. Age (χ(2)=11.79, P value = 0.008), literacy (χ(2)=17.95, P value = 0.03), duration of marriage (χ(2)=14.23, P value = 0.008) and number of children (χ(2)=10.45, P value = 0.01) were significant for acceptance of NSV. Among the predictors, method suggested by peer/ health worker (OR = 1.5, P value = 0.01), method does not require regular intervention (OR = 1.3, P value = 0.004) and permanence of the method (OR = 1.2, P value = 0.031) were significant. Acceptors were most satisfied with the shorter duration required to return to work and the most common complication was persistent postoperative pain among 12 (10.34%) of the acceptors. Advocating and implementing family planning is of high significance in view of the population growth in India and drawing from the demographic profile, predictors, pool of trainers and experiences in Karimnagar District, a similar achievement of higher rates of this simple procedure with few complications can be replicated.

Several new compounds are now available for castration resistant prostate cancer (CRPC). Individual costs range between $40,000 and $93,000 with mean survival extensions from 2.4 to 4.8 months. Currently, it remains unclear how patients with prostate cancer (PCa) value the effect of these therapies in the setting of CRPC. To assess patient understanding of core cancer concepts, opinions on the cost and overall benefit of CRPC drugs, whether out-of-pocket costs would change opinions and whether patients would ultimately opt out of CRPC drug treatment for an end-of-life (EOL) premium. We conducted a qualitative survey among patients with various PCa states ranging from active surveillance to CRPC and from various familial, financial and educational demographics. Through a series of hypothetical scenarios, we extrapolated opinions on CRPC drug value, efficacy and monetary worth. We assessed patient willingness to accept an EOL ($50,000) premium in lieu of CRPC drug treatment. Statistically, chi-squared analysis and Fisher's exact test were used when appropriate. In total, 103 patients completed the questionnaire, one-half of whom did not understand "advanced PCa" state and more than one-third of the concept of palliative care despite multiple meetings with Urologists. Patients willingness-to-pay and proposed drug value was higher than that accepted by government when government funded, with costs exceeding $250,000 per person, but lower than that accepted by government when self-funded. A majority (60%) would accept/consider the EOL premium in the setting of CRPC. Patients with higher education were more skeptical about CRPC drug value and more likely to accept the EOL premium (P = 0.003.) CONCLUSION: Patients have an incomplete understanding of their own disease prognosis and its therapeutic options. This ultimately influences patient decision-making. Education, income and out-of-pocket costs diminished opinion of CRPC drugs considerably. As such, an EOL premium should be considered in subsets of patients. Crown Copyright © 2018.

Watts, J. W.; Armstrong, T. W.; Colborn, B. L.

1996-01-01

Predictions of the LDEF mission's trapped proton and electron and galactic cosmic ray proton exposures have been made using the currently accepted models with improved resolution near mission end and better modeling of solar cycle effects. An extension of previous calculations, to provide a more definitive description of the LDEF exposure to ionizing radiation, is represented by trapped proton and electron flux as a function of mission time, presented considering altitude and solar activity variation during the mission and the change in galactic cosmic ray proton flux over the mission. Modifications of the AP8MAX and AP8MIN fluence led to a reduction of fluence by 20%. A modified interpolation model developed by Daly and Evans resulted in 30% higher dose and activation levels, which better agreed with measured values than results predicted using the Vette model.

Closed-circuit ejector cooling systems have never in the past achieved acceptable operating efficiencies in their vapor-compression cycle using standard refrigerants. Despite their long history, relative simplicity, quietness, rugged design, low maintenance and low cost, they could not compete with electric-motor-driven compressors. Phase I is an assessment of two immiscible fluids in an ejector cooling system with different latent heat capacity and molecular weights intended to require less heat in the boiler producing the propellant and taking more heat out in the evaporator cooling fluid. Actual tests corrected to standard conditions and neglecting thermal losses showed 0.5 closed-cycle thermal COP (excludingmore » stack losses), higher than ever previously achieved but below original expectations. Computer programs developed indicate higher COP values are attainable along with competitive first costs.« less

An upgraded interferometer-polarimeter system for broadband fluctuation measurements

Measuring high-frequency fluctuations (above tearing mode frequencies) is important for diagnosing instabilities and transport phenomena. The Madison Symmetric Torus interferometer-polarimeter system has been upgraded to utilize improved planar-diode mixer technology. The new mixers reduce phase noise and allow more sensitive measurements of fluctuations at high frequency. Typical polarimeter rms phase noise values of 0.05°–0.07° are obtained with 400 kHz bandwidth. The low phase noise enables the resolution of fluctuations up to 250 kHz for polarimetry and 600 kHz for interferometry. The importance of probe beam alignment for polarimetry is also verified; previously reported tolerances of ≤0.1 mm displacement for equilibriummore » and tearing mode measurements minimize contamination due to spatial misalignment to within acceptable levels for chords near the magnetic axis.« less

Sea urchin gonads are highly valued seafood that degenerates rapidly during the storage period. To study the influence of dissolved oxygen concentration on quality changes of sea urchin (Strongylocentrotus nudus) gonads, they were stored in artificial seawater saturated with oxygen, nitrogen or air at 5 ± 1 °C for 12 days. The sensory acceptability limit was 11-12, 6-7 and 7-8 days for gonads with oxygen, nitrogen or air packaging, respectively. Total volatile basic nitrogen (TVB-N) values reached 22.60 ± 1.32, 32.37 ± 1.37 and 24.91 ± 1.54 mg 100 g(-1) for gonads with oxygen, nitrogen or air packaging at the points of near to, exceeding and reaching the limit of sensory acceptability, indicating that TVB-N values of about 25 mg 100 g(-1) should be regarded as the limit of acceptability for sea urchin gonads. Relative ATP content values were 56.55%, 17.36% and 18.75% for gonads with oxygen, nitrogen or air packaging, respectively, on day 2. K-values were 19.37%, 25.05% and 29.02% for gonads with oxygen, nitrogen or air packaging, respectively, on day 2. Both pH and aerobic plate count values showed no significant difference (P > 0.05) for gonads with the three treatments. Gonads with oxygen packaging had lower sensory demerit point (P < 0.05) and TVB-N values (P < 0.05), and higher relative ATP content (P < 0.01) and K-values (P < 0.05), than that with nitrogen or air packaging, with an extended shelf life of 4-5 days during storage in artificial seawater at 5 ± 1 °C.

Embedded care managers are increasingly implemented as part of the care team within primary care practices, yet previous studies have indicated variability in acceptance by physicians and staff. This study assesses the acceptability of care managers among staff and physicians within the Michigan Primary Care Transformation (MiPCT) demonstration. Care manager acceptance was measured using a web-based survey distributed to practices participating in the MiPCT demonstration. Both physicians and staff reported high levels of care manager acceptance. Longer length of care manager employment at the practice, higher care manager FTE dedicated to care management, and care manager employed by practice were all significantly associated with care manager acceptance. The MiPCT demonstration found high care manager acceptance across all care team members. The high level of acceptance may be due to the structures and processes developed by MiPCT to support implementation of care managers and the length of the intervention period. The MiPCT demonstration confirms that following three years of implementation, embedded care managers are acceptable to both physicians and staff within primary care practices. Importantly, embeddedness, or the amount of time care managers are located within practices, is associated with increased acceptance. © Copyright 2017 by the American Board of Family Medicine.

Experimental characterization of the AFIT neutron facility. Master's thesis

1993-09-01

AFIT's Neutron Facility was characterized for room-return neutrons using a (252)Cf source and a Bonner sphere spectrometer with three experimental models, the shadow shield, the Eisenhauer, Schwartz, and Johnson (ESJ), and the polynomial models. The free-field fluences at one meter from the ESJ and polynomial models were compared to the equivalent value from the accepted experimental shadow shield model to determine the suitability of the models in the AFIT facility. The polynomial model behaved erratically, as expected, while the ESJ model compared to within 4.8% of the shadow shield model results for the four Bonner sphere calibration. The ratio ofmore » total fluence to free-field fluence at one meter for the ESJ model was then compared to the equivalent ratio obtained by a Monte Cario Neutron-Photon transport code (MCNP), an accepted computational model. The ESJ model compared to within 6.2% of the MCNP results. AFIT's fluence ratios were compared to equivalent ratios reported by three other neutron facilities which verified that AFIT's results fit previously published trends based on room volumes. The ESJ model appeared adequate for health physics applications and was chosen was chosen for calibration of the AFIT facility.

The use of energy beverages is high among the general population and military personnel. Previous studies have reported discrepancies between the actual amount of caffeine in products and the amount of caffeine on stated labels. Thus, the purpose of this study was to examine the content of caffeine listed on the labels of various energy drinks and energy shots. Top-selling energy drinks (n = 9) and energy shots (n = 5) were purchased from retail stores. Three of each of the 14 products were purchased and analyzed for caffeine content by an independent laboratory. Of the 14 products tested, 5 did not provide caffeine amounts on their facts panel-of those, 3 listed caffeine as an ingredient and 2 listed caffeine as part of a proprietary blend. The remaining 9 (of 14) products stated the amounts of caffeine on their labels, all of which were within 15% of the amount indicated on the label. In this study, although the energy beverages that indicated the amount of caffeine it contained had values within ±15% of the amount listed on the label, a potentially acceptable range, this finding is not acceptable with regard to current labeling regulations, which require added ingredients to total 100%.

Genetic testing will soon enter care for human immunodeficiency virus (HIV) and hepatitis C virus (HCV), and for addiction. There is a paucity of data on how to disseminate genetic testing into healthcare for marginalized populations. We explored drug users' perceptions of genetic testing. Six focus groups were conducted with 34 drug users recruited from syringe exchange programmes and an HIV clinic between May and June 2012. Individual interviews were conducted with participants reporting previous genetic testing. All participants expressed acceptance of genetic testing to improve care, but most had concerns regarding confidentiality and implications for law enforcement. Most expressed more comfort with genetic testing based on individual considerations rather than testing based on race/ethnicity. Participants expressed comfort with genetic testing in medical care rather than drug treatment settings and when specifically asked permission, with peer support, and given a clear rationale. Although participants understood the potential value of genetic testing, concerns regarding breaches in confidentiality and discrimination may reduce testing willingness. Safeguards against these risks, peer support, and testing in medical settings based on individual factors and with clear rationales provided may be critical in efforts to promote acceptance of genetic testing among drug users.

Consumer Acceptability of Intramuscular Fat

PubMed Central

Frank, Damian; Joo, Seon-Tea

2016-01-01

Fat in meat greatly improves eating quality, yet many consumers avoid visible fat, mainly because of health concerns. Generations of consumers, especially in the English-speaking world, have been convinced by health authorities that animal fat, particularly saturated or solid fat, should be reduced or avoided to maintain a healthy diet. Decades of negative messages regarding animal fats has resulted in general avoidance of fatty cuts of meat. Paradoxically, low fat or lean meat tends to have poor eating quality and flavor and low consumer acceptability. The failure of low-fat high-carbohydrate diets to curb “globesity” has prompted many experts to re-evaluate of the place of fat in human diets, including animal fat. Attitudes towards fat vary dramatically between and within cultures. Previous generations of humans sought out fatty cuts of meat for their superior sensory properties. Many consumers in East and Southeast Asia have traditionally valued more fatty meat cuts. As nutritional messages around dietary fat change, there is evidence that attitudes towards animal fat are changing and many consumers are rediscovering and embracing fattier cuts of meat, including marbled beef. The present work provides a short overview of the unique sensory characteristics of marbled beef and changing consumer preferences for fat in meat in general. PMID:28115880

The aim was to investigate the reliability and validity of the Socially Valued Role Classification Scale (SRCS), a domain-specific measure of role functioning designed for use with community residents with psychiatric disabilities. Test-retest reliability, concurrent validity, face validity, consumer and clinician acceptability and utility were examined. Sixty community residents with schizophrenia or schizoaffective disorder participated in this study where the SRCS was administered by telephone. Test-retest reliability showed good or very good agreement for subscale scores (intraclass correlations (ICCs): 0.78-0.89) and for items capturing amount of participation in domain-specific activities (ICC: 0.67-1.00). Greater variation was observed for items capturing assistance required with activities (κ: 0.40-0.75), and standard of activities performed (κ: 0.43-1.00). Concurrent validity was supported by moderate to very good associations in the directions expected. Face validity, user acceptability and utility in telephone interviews were adequate. These findings add to previous psychometric evidence and support the continued development of the SRCS for use in community mental health settings. The SRCS has promising utility for occupational therapists involved in psychiatric rehabilitation outcome measurement. © 2011 Queensland Health - QCMHR.

Natural radioactivity due to (226)Ra, (232)Th and (40)K in the common building materials collected from Baotou city of Inner Mongolia, China was measured using gamma-ray spectrometry. The radiation hazard of the studied building materials was estimated by the radium equivalent activity (Ra(eq)), internal hazard index (H(in)) and annual effective dose (AED). The concentrations of the natural radionuclides and Ra(eq) in the studied samples were compared with the corresponding results of other countries. The Ra(eq) values of the building materials are below the internationally accepted values (370 Bq kg(-1)). The values of H(in) in all studied building materials are less than unity. The AEDs of all measured building materials are at an acceptable level.

The aim of the current study was to use Structural Equation Modelling (SEM) to examine whether psychological flexibility (i.e. mindfulness, acceptance, valued-living) mediates the relationship between distress, irritable bowel syndrome (IBS) symptom frequency, and quality of life (QoL). Ninety-two individuals participated in the study (12 male, 80 female, M age  = 36.24) by completing an online survey including measures of visceral sensitivity, distress, IBS-related QoL, mindfulness, bowel symptoms, pain catastrophizing, acceptance, and valued-living. A final model with excellent fit was identified. Psychological distress significantly and directly predicted pain catastrophizing, valued-living, and IBS symptom frequency. Pain catastrophizing directly predicted visceral sensitivity and acceptance, while visceral sensitivity significantly and directly predicted IBS symptom frequency and QoL. Symptom frequency also had a direct and significant relationship with QoL. The current findings suggest that interventions designed to address unhelpful cognitive processes related to visceral sensitivity, pain catastrophizing, and psychological distress may be of most benefit to IBS-related QoL.

Design of Raft Foundations for High-Rise Buildings on Jointed Rock

This paper presents calculations of displacements and bending moments in a 2-m-thick reinforced-concrete foundation slab using three-dimensional finite-element software. A preliminary paper was presented by Justo et al. (Rock Mech Rock Eng 43:287-304, 2010). The slab is the base of a tower of 137 m height above foundation, supported on jointed and partly weathered basalt and scoria. Installation of rod extensometers at different depths below foundation allowed comparison between measured displacements and displacements calculated using moduli obtained from rock classification systems and three material models: elastic, Mohr-Coulomb and hardening (H). Although all three material models can provide acceptable results, the H model is preferable when there are unloading processes. Acceptable values of settlement may be achieved with medium meshing and an approximate distribution of loads. The absolute values of negative bending moments (tensions below) increase as the rock mass modulus decreases or when the mesh is refined. The paper stresses the importance of adequately representing the details of the distribution of loads and the necessity for fine meshing to obtain acceptable values of bending moments.

Single-step models including dominance can be an enormous computational task and can even be prohibitive for practical application. In this study, we try to answer the question whether a reduced single-step model is able to estimate breeding values of bulls and breeding values, dominance deviations and total genetic values of cows with acceptable quality. Genetic values and phenotypes were simulated (500 repetitions) for a small Fleckvieh pedigree consisting of 371 bulls (180 thereof genotyped) and 553 cows (40 thereof genotyped). This pedigree was virtually extended for 2,407 non-genotyped daughters. Genetic values were estimated with the single-step model and with different reduced single-step models. Including more relatives of genotyped cows in the reduced single-step model resulted in a better agreement of results with the single-step model. Accuracies of genetic values were largest with single-step and smallest with reduced single-step when only the cows genotyped were modelled. The results indicate that a reduced single-step model is suitable to estimate breeding values of bulls and breeding values, dominance deviations and total genetic values of cows with acceptable quality. © 2018 Blackwell Verlag GmbH.

Total DNA of a population of uncultured organisms was extracted from soil samples, and by using PCR methods, the genes encoding two different 2,5-diketo-D-gluconic acid reductases (DKGRs) were recovered. Degenerate PCR primers based on published sequence information gave internal gene fragments homologous to known DKGRs. Nested primers specific for the internal fragments were combined with random primers to amplify flanking gene fragments from the environmental DNA, and two hypothetical full-length genes were predicted from the combined sequences. Based on these predictions, specific primers were used to amplify the two complete genes in single PCRs. These genes were cloned and expressedmore » in Escherichia coli. The purified gene products catalyzed the reduction of 2,5-diketo-D-gluconic acid to 2-keto-L-gulonic acid. Compared to previously described DKGRs isolated from Corynebacterium spp., these environmental reductases possessed some valuable properties. Both exhibited greater than 20-fold-higher k{sub cat}/K{sub m} values than those previously determined, primarily as a result of better binding of substrate. The K{sub m} values for the two new reductases were 57 and 67 {mu}M, versus 2 and 13 mM for the Corynebacterium enzymes. Both environmental DKGRs accepted NADH as well as NADPH as a cosubstrate; other DKGRs and most related aldo-keto reductases use only NADPH. In addition, one of the new reductases was more thermostable than known DKGRs.« less

Necessary constraints for an equation of state to be physically acceptable

2018-04-01

We have pointed out the constraints required for an equation of state (EOS) to be physically acceptable and universally applicable for the entire range of compressions for a material at high pressures. We have discussed the boundary conditions valid at zero pressure and infinite pressure. The concept of infinite pressure behavior has been discussed. It has been emphasized that the Stacey reciprocal K-primed EOS satisfies all the necessary criterion for the validity of EOS. On the other hand, equations of state reported previously do not satisfy the condition of physical acceptability of an equation of state.

The objective of this study was to determine if Chardonnay grape seed pomace (GSP), a waste stream of wine production, could be used as a functional ingredient in brewed coffee. Two consumer panels were conducted to assess the acceptance of coffee at coffee replacement (w/w) values of 0% (control), 6.25%, 12.50%, 18.75%, or 25% GSP. The 1st consumer panel (n = 80) assessed the coffee samples served "black." The 2nd panel (n = 67) assessed the coffee samples with adjustment (that is, sweeteners, milk, and cream) options available. Consumer sensory evaluation involved evaluating the 5 treatments individually for acceptance of appearance, aroma, taste/flavor, and overall acceptance using a 9-point hedonic scale. A check-all-that-apply questionnaire surveyed the sensory attributes describing aroma, appearance, and taste/flavor of the samples. Oxygen radical absorbance capacity was used to measure the effects of antioxidant levels in GSP coffee samples. Results showed that GSP could be added at 6.25% replacement without significantly affecting the overall consumer acceptance of coffee compared to the control (0% GSP). Above 6.25% GSP supplementation, the coffee beverage was described as more tan, milky, watery/dilute, and mild, and was generally less accepted by the consumers. GSP also increased the antioxidant capacity of the coffee compared to the control (0% GSP), with no significant differences among replacement values. Therefore, 6.25% GSP replacement is recommended for creating coffee beverages acceptable to consumers. Further in vivo investigation may substantiate the free-radical scavenging capacity of GSP coffee and its potential health benefits. © 2016 Institute of Food Technologists®.

Evaluation of Brain Iron Content Based on Magnetic Resonance Imaging (MRI): Comparison among Phase Value, R2* and Magnitude Signal Intensity

PubMed Central

Yan, Shen-Qiang; Sun, Jian-Zhong; Yan, Yu-Qing; Wang, He; Lou, Min

2012-01-01

Background and Purpose Several magnetic resonance imaging (MRI) techniques are being exploited to measure brain iron levels increasingly as iron deposition has been implicated in some neurodegenerative diseases. However, there remains no unified evaluation of these methods as postmortem measurement isn't commonly available as the reference standard. The purpose of this study was to make a comparison among these methods and try to find a new index of brain iron. Methods We measured both phase values and R2* in twenty-four adults, and performed correlation analysis among the two methods and the previously published iron concentrations. We also proposed a new method using magnitude signal intensity and compared it with R2* and brain iron. Results We found phase value correlated with R2* in substantia nigra (r = −0.723, p<0.001) and putamen (r = −0.514, p = 0.010), while no correlations in red nucleus (r = −0.236, p = 0.268) and globus pallidus (r = −0.111, p = 0.605). And the new magnitude method had significant correlations in red nucleus (r = −0.593, p = 0.002), substantia nigra (r = −0.521, p = 0.009), globus pallidus (r = −0.750, p<0.001) and putamen (r = −0.547, p = 0.006) with R2*. A strong inverse correlation was also found between the new magnitude method and previously published iron concentrations in seven brain regions (r = −0.982, P<0.001). Conclusions Our study indicates that phase value may not be used for assessing the iron content in some brain regions especially globus pallidus. The new magnitude method is highly consistent with R2* especially in globus pallidus, and we assume that this approach may be acceptable as an index of iron content in iron-rich brain regions.

A critical flaw in Branigan & Pickering's (B&P's) advocacy of structural priming is the absence of a theory of priming. This undermines their claims about the value of priming as a methodology. In contrast, acceptability judgments enable clearer inferences about structure. It is important to engage thoroughly with the logic behind different structural diagnostics.

Physiologic correlates to background noise acceptance

NASA Astrophysics Data System (ADS)

Tampas, Joanna; Harkrider, Ashley; Nabelek, Anna

2004-05-01

Acceptance of background noise can be evaluated by having listeners indicate the highest background noise level (BNL) they are willing to accept while following the words of a story presented at their most comfortable listening level (MCL). The difference between the selected MCL and BNL is termed the acceptable noise level (ANL). One of the consistent findings in previous studies of ANL is large intersubject variability in acceptance of background noise. This variability is not related to age, gender, hearing sensitivity, personality, type of background noise, or speech perception in noise performance. The purpose of the current experiment was to determine if individual differences in physiological activity measured from the peripheral and central auditory systems of young female adults with normal hearing can account for the variability observed in ANL. Correlations between ANL and various physiological responses, including spontaneous, click-evoked, and distortion-product otoacoustic emissions, auditory brainstem and middle latency evoked potentials, and electroencephalography will be presented. Results may increase understanding of the regions of the auditory system that contribute to individual noise acceptance.

Effects of major-road vehicle speed and driver age and gender on left-turn gap acceptance.

PubMed

Yan, Xuedong; Radwan, Essam; Guo, Dahai

2007-07-01

Because the driver's gap-acceptance maneuver is a complex and risky driving behavior, it is a highly concerned topic for traffic safety and operation. Previous studies have mainly focused on the driver's gap acceptance decision itself but did not pay attention to the maneuver process and driving behaviors. Using a driving simulator experiment for left-turn gap acceptance at a stop-controlled intersection, this study evaluated the effects of major traffic speed and driver age and gender on gap acceptance behaviors. The experiment results illustrate relationships among drivers' left-turn gap decision, driver's acceleration rate, steering action, and the influence of the gap-acceptance maneuver on the vehicles in the major traffic stream. The experiment results identified an association between high crash risk and high traffic speed at stop-controlled intersections. The older drivers, especially older female drivers, displayed a conservative driving attitude as a compensation for reduced driving ability, but also showed to be the most vulnerable group for the relatively complex driving maneuvers.

Social acceptance and self-esteem: tuning the sociometer to interpersonal value.

PubMed

Anthony, Danu B; Holmes, John G; Wood, Joanne V

The authors draw on sociometer theory to propose that self-esteem is attuned to traits that garner others' acceptance, and the traits that garner acceptance depend on one's social role. Attunement of self-esteem refers to the linkage, or connection, between self-esteem and specific traits, which may be observed most clearly in the association between self-esteem and specific self-evaluations. In most roles, appearance and popularity determine acceptance, so self-esteem is most attuned to those traits. At the same time, interdependent social roles emphasize the value of communal qualities, so occupants of those roles have self-esteem that is more attuned to communal qualities than is the general norm. To avoid the biases of people's personal theories, the authors assessed attunement of self-esteem to particular traits indirectly via the correlation between self-esteem and self-ratings, cognitive accessibility measures, and an experiment involving social decision making. As hypothesized, self-esteem was generally more attuned to appearances than to communal qualities, but interdependent social roles predicted heightened attunement of self-esteem to qualities like kindness and understanding.

Getting to Darwin: Obstacles to Accepting Evolution by Natural Selection

NASA Astrophysics Data System (ADS)

Thagard, Paul; Findlay, Scott

2010-06-01

Darwin’s theory of evolution by natural selection is central to modern biology, but is resisted by many people. This paper discusses the major psychological obstacles to accepting Darwin’s theory. Cognitive obstacles to adopting evolution by natural selection include conceptual difficulties, methodological issues, and coherence problems that derive from the intuitiveness of alternative theories. The main emotional obstacles to accepting evolution are its apparent conflict with valued beliefs about God, souls, and morality. We draw on the philosophy of science and on a psychological theory of cognitive and emotional belief revision to make suggestions about what can be done to improve acceptance of Darwinian ideas.

We present here the methodology and results of the Operational Acceptance Test (OAT) performed on the new Kennedy Space Center (KSC) 50-MHz Doppler Radar Wind Profiler (DRWP). On day-of-launch (DOL), space launch vehicle operators have used data from the DRWP to invalidate winds in prelaunch loads and trajectory assessments due to the DRWP's capability to quickly identify changes in the wind profile within a rapidly-changing wind environment. The previous DRWP has been replaced with a completely new system, which needs to undergo certification testing before being accepted for use in range operations. The new DRWP replaces the previous three-beam system made of coaxial cables and a copper wire ground plane with a four-beam system that uses Yagi antennae with enhanced beam steering capability. In addition, the new system contains updated user interface software while maintaining the same general capability as the previous system. The new DRWP continues to use the Median Filter First Guess (MFFG) algorithm to generate a wind profile from Doppler spectra at each range gate. DeTect (2015) contains further details on the upgrade. The OAT is a short-term test designed so that end users can utilize the new DRWP in a similar manner to the previous DRWP during mission operations at the Eastern Range in the midst of a long-term certification process. This paper describes the Marshall Space Flight Center Natural Environments Branch's (MSFC NE's) analyses to verify the quality and accuracy of the DRWP's meteorological data output as compared to the previous DRWP. Ultimately, each launch vehicle program has the responsibility to certify the system for their own use.

Has the UK Clinical Aptitude Test improved medical student selection?

Wright, Sarah R; Bradley, Philip M

2010-11-01

In 2006, the United Kingdom Clinical Aptitude Test (UKCAT) was introduced as a new medical school admissions tool. The aim of this cohort study was to determine whether the UKCAT has made any improvements to the way medical students are selected. Regression analysis was performed in order to study the ability of previous school type and gender to predict UKCAT, personal statement or interview scores in two cohorts of accepted students. The ability of admissions scores and demographic data to predict performance on knowledge and skills examinations was also studied. Previous school type was not a significant predictor of either interview or UKCAT scores amongst students who had been accepted onto the programme (n = 307). However, it was a significant predictor of personal statement score, with students from independent and grammar schools performing better than students from state-maintained schools. Previous school type, personal statements and interviews were not significant predictors of knowledge examination performance. UKCAT scores were significant predictors of knowledge examination performance for all but one examination administered in the first 2 years of medical school. Admissions data explained very little about performance on skills (objective structured clinical examinations [OSCEs]) assessments. The use of personal statements as a basis for selection results in a bias towards students from independent and grammar schools. However, no evidence was found to suggest that students accepted from these schools perform any better than students from maintained schools on Year 1 and 2 medical school examinations. Previous school type did not predict interview or UKCAT scores of accepted students. UKCAT scores are predictive of Year 1 and 2 examination performance at this medical school, whereas interview scores are not. The results of this study challenge claims made by other authors that aptitude tests do not have a place in medical school selection in the UK. © Blackwell Publishing Ltd 2010.

Although there are current efforts to integrate herbal medicine (HM) into mainstream healthcare in Ghana, there is paucity of empirical evidence on the acceptability and concurrent use of HM, in the formal health facilities in Ghana. This study sought to determine client perception, disclosure and acceptability of integrating herbal medicine in mainstream healthcare in Kumasi, Ghana. A cross-sectional study was conducted from May to August, 2015. Five hundred patients presenting at the outpatient departments of Kumasi South, Suntreso and Tafo Government Hospitals in Kumasi were randomly selected. Interviews were conducted with the use of structured questionnaires. A logistic regression analysis, using backward selection, was conducted to determine the influence of socio-demographic and facility related factors on the odds of using HM at the facility. All statistical tests were two-sided and considered significant at a p-value of <0.05. Majority of the study respondents were females (64.8%) and the median age was 36 years. Less than half, 42.2%, of the respondents utilized HM services when they visited the health facility. Reasons for using HM at the facility level included 'being effective' (24.4%), 'easy to access' (25.3%) and 'being comparatively cheaper' (16%). About 86% never disclosed previous use of HM to their health care providers. Socio-economic status and perception of service provision influenced use of herbal medicines. Respondents who rated themselves wealthy had increased odds of using herbal medicines at the health facility as compared to those who rated themselves poor (OR = 4.9; 95%CI = 1.6-15.3). This study shows that integration of herbal medicine is feasible and herbal medicines may be generally accepted as a formal source of healthcare in Ghana. The results of this study might serve as a basis for improvement and upscale of the herbal medicine integration programme in Ghana.

Objectives To explore factors influencing the likelihood of antenatal vaccine acceptance of both routine UK antenatal vaccines (influenza and pertussis) and a hypothetical group B Streptococcus (GBS) vaccine in order to improve understanding of how to optimise antenatal immunisation acceptance, both in routine use and clinical trials. Setting An online survey distributed to women of childbearing age in the UK. Participants 1013 women aged 18–44 years in England, Scotland and Wales. Methods Data from an online survey conducted to gauge the attitudes of 1013 women of childbearing age in England, Scotland and Wales to antenatal vaccination against GBS were further analysed to determine the influence of socioeconomic status, parity and age on attitudes to GBS immunisation, using attitudes to influenza and pertussis vaccines as reference immunisations. Factors influencing likelihood of participation in a hypothetical GBS vaccine trial were also assessed. Results Women with children were more likely to know about each of the 3 conditions surveyed (GBS: 45% vs 26%, pertussis: 79% vs 63%, influenza: 66% vs 54%), to accept vaccination (GBS: 77% vs 65%, pertussis: 79% vs 70%, influenza: 78% vs 68%) and to consider taking part in vaccine trials (37% vs 27% for a hypothetical GBS vaccine tested in 500 pregnant women). For GBS, giving information about the condition significantly increased the number of respondents who reported that they would be likely to receive the vaccine. Health professionals were the most important reported source of information. Conclusions Increasing awareness about GBS, along with other key strategies, would be required to optimise the uptake of a routine vaccine, with a specific focus on informing women without previous children. More research specifically focusing on acceptability in pregnant women is required and, given the value attached to input from healthcare professionals, this group should be included in future studies.

Development, Implementation, and Evaluation of a Telemedicine Service for the Treatment of Acute Stroke Patients: TeleStroke

PubMed Central

2012-01-01

Background Health care service based on telemedicine can reduce both physical and time barriers in stroke treatments. Moreover, this service connects centers specializing in stroke treatment with other centers and practitioners, thereby increasing accessibility to neurological specialist care and fibrinolytic treatment. Objective Development, implementation, and evaluation of a care service for the treatment of acute stroke patients based on telemedicine (TeleStroke) at Virgen del Rocío University Hospital. Methods The evaluation phase, conducted from October 2008 to January 2011, involved patients who presented acute stroke symptoms confirmed by the emergency physician; they were examined using TeleStroke in two hospitals, at a distance of 16 and 110 kilometers from Virgen del Rocío University Hospital. We analyzed the number of interconsultation sheets, the percentage of patients treated with fibrinolysis, and the number of times they were treated. To evaluate medical professionals’ acceptance of the TeleStroke system, we developed a web-based questionnaire using a Technology Acceptance Model. Results A total of 28 patients were evaluated through the interconsultation sheet. Out of 28 patients, 19 (68%) received fibrinolytic treatment. The most common reasons for not treating with fibrinolysis included: clinical criteria in six out of nine patients (66%) and beyond the time window in three out of nine patients (33%). The mean “onset-to-hospital” time was 69 minutes, the mean time from admission to CT image was 33 minutes, the mean “door-to-needle” time was 82 minutes, and the mean “onset-to-needle” time was 150 minutes. Out of 61 medical professionals, 34 (56%) completed a questionnaire to evaluate the acceptability of the TeleStroke system. The mean values for each item were over 6.50, indicating that respondents positively evaluated each item. This survey was assessed using the Cronbach alpha test to determine the reliability of the questionnaire and the results obtained, giving a value of 0.97. Conclusions The implementation of TeleStroke has made it possible for patients in the acute phase of stroke to receive effective treatment, something that was previously impossible because of the time required to transfer them to referral hospitals.

Consumer acceptance of technology-based food innovations: lessons for the future of nutrigenomics.

2007-07-01

Determinants of consumer adoption of innovations have been studied from different angles and from the perspectives of various disciplines. In the food area, the literature is dominated by a focus on consumer concern. This paper reviews previous research into acceptance of technology-based innovation from both inside and outside the food domain, extracts key learnings from this literature and integrates them into a new conceptual framework for consumer acceptance of technology-based food innovations. The framework distinguishes 'distal' and 'proximal' determinants of acceptance. Distal factors (characteristics of the innovation, the consumer and the social system) influence consumers' intention to accept an innovation through proximal factors (perceived cost/benefit considerations, perceptions of risk and uncertainty, social norm and perceived behavioural control). The framework's application as a tool to anticipate consumer reaction to future innovations is illustrated for an actual technology-based innovation in food science, nutrigenomics (the interaction between nutrition and human genetics).

Contents of 16 polycyclic aromatic hydrocarbons were analyzed in 30 soil samples from 15 locations in Novi Sad, Serbia, assessing for the first time the corresponding health risks in the Serbian urban zone. Total concentrations were in the range of 22-2247 μg kg -1 , with a mean and median value of 363 and 200 μg kg -1 , respectively. Comparison with the relevant maximum allowed contents proposed by the Serbian government and with the Dutch target values implied that soils from the urban area of Novi Sad were "suitable as residential soils" and that no intervention would be needed if the current levels were retained. Seven diagnostic ratios were calculated, indicating the pyrogenic sources of PAHs as the dominant. Cancer risks in humans via accidental ingestion, inhalation of soil particles, and dermal contact with soil were estimated. Cancer risk for soil ingestion by children was the highest. The total lifetime carcinogenic risk as sum of individual cancer risks for seven carcinogenic polycyclic aromatic hydrocarbons was within the range 10 -4 to 10 -6 , indicating acceptable risks at 30 and 47% of sites for children and adults, respectively. However, for the rest of the samples, total lifetime cancer risk was >10 -4 indicating over the acceptable risk, even though the contents in soil were not of concern as the comparison with the environmental guidance previously showed. This could be explained by (a) the dominant concentrations of higher molecular weight compounds with 4 to 6 rings, among which there are compounds with higher toxicity equivalents, but also with (b) the extreme conditions used for the conservative risk assessment under maximal exposure frequency, exposure time, and ingestion rates.

DNAPL sources of carbon tetrachloride (CT) vapors are of interest at the Radioactive Waste Management Complex (RWMC) at the Idaho National Engineering and Environmental Laboratory (INEEL). The site is underlain by thick fractured basalt that includes sedimentary interbeds, each are a few meters thick. Daily atmospheric pressure fluctuations serve as driving forces for CT vapor transport in the subsurface. Other important transport processes for vapor movement include gas-phase diffusion and density-driven transport. The objective of this research is to investigate the influence and relative importance of these processes on gaseous transport of CT. Gas pressure and vapor concentration measurements were conducted at various depths in two wells. A numerical multiphase flow model (TOUGH2), calibrated to field pressure data, is used to conduct sensitivity analyses to elucidate the importance of the different transport mechanisms. Results show that the basalt is highly permeable to vertical air flow. The pressure dampening occurs mainly in the sedimentary interbeds. Model-calibrated permeability values for the interbeds are similar to those obtained in a study by the U.S. Geological Survey for shallow sediments, and an order of magnitude higher than column-scale values obtained by previous studies conducted by INEEL scientists. The transport simulations indicate that considering the effect of barometric pressure changes is critical to simulating transport of pollutants in the vadose zone above the DNAPL source. Predicted concentrations can be orders of magnitude smaller than actual concentrations if the effect is not considered. Below the DNAPL vapor source, accounting for density and diffusion alone would yield acceptable results provided that a 20% error in concentrations are acceptable, and that simulating concentrations trends (and not actual concentrations) is the primary goal.

Current methods of assessing nerve blocks, such as loss of perception to cold sensation, are subjective at best. Transcutaneous nerve stimulation is an alternative method that has previously been used to measure the current perception threshold (CPT) in individuals with neuropathic conditions, and various devices to measure CPT are commercially available. Nevertheless, the device must provide reproducible results to be used as an objective tool for assessing nerve blocks. We recruited ten healthy volunteers to examine CPT reproducibility using the Neurometer(®) and the Stimpod NMS450 peripheral nerve stimulator. Each subject's CPT was determined for the median (second digit) and ulnar (fifth digit) nerve sensory distributions on both hands - with the Neurometer at 5 Hz, 250 Hz, and 2000 Hz and with the Stimpod at pulse widths of 0.1 msec, 0.3 msec, 0.5 msec, and 1.0 msec, both at 5 Hz and 2 Hz. Intraclass correlation coefficients (ICC) were also calculated to assess reproducibility; acceptable ICCs were defined as ≥ 0.4. The ICC values for the Stimpod ranged from 0.425-0.79, depending on pulse width, digit, and stimulation; ICCs for the Neurometer were 0.615 and 0.735 at 250 and 2,000 Hz, respectively. These values were considered acceptable; however, the Neurometer performed less efficiently at 5 Hz (ICCs for the second and fifth digits were 0.292 and 0.318, respectively). Overall, the Stimpod device displayed good to excellent reproducibility in measuring CPT in healthy volunteers. The Neurometer displayed poor reproducibility at low frequency (5 Hz). These results suggest that peripheral nerve stimulators may be potential devices for measuring CPT to assess nerve blocks.

The decision-making process for the fate of frozen embryos by Japanese infertile women: a qualitative study

2012-01-01

Background Previous studies have found that the decision-making process for stored unused frozen embryos involves much emotional burden influenced by socio-cultural factors. This study aims to ascertain how Japanese patients make a decision on the fate of their frozen embryos: whether to continue storage discard or donate to research. Methods Ten Japanese women who continued storage, 5 who discarded and 16 who donated to research were recruited from our infertility clinic. Tape-recorded interviews were transcribed and analyzed for emergent themes. Results A model of patients’ decision-making processes for the fate of frozen embryos was developed, with a common emergent theme, “coming to terms with infertility” resulting in either acceptance or postponing acceptance of their infertility. The model consisted of 5 steps: 1) the embryo-transfer moratorium was sustained, 2) the “Mottainai”- embryo and having another child were considered; 3) cost reasonability was taken into account; 4) partner’s opinion was confirmed to finally decide whether to continue or discontinue storage. Those discontinuing, then contemplated 5): the effect of donation. Great emotional conflict was expressed in the theme, steps 2, 4, and 5. Conclusions Patients’ 5 step decision-making process for the fate of frozen embryos was profoundly affected by various Japanese cultural values and moral standards. At the end of their decision, patients used culturally inherent values and standards to come to terms with their infertility. While there is much philosophical discussion on the moral status of the embryo worldwide, this study, with actual views of patients who own them, will make a significant contribution to empirical ethics from the practical viewpoint.

This study examines in detail the psychological variables underlying ideological political orientation, and structure and contents of this orientation, in Sweden and Latvia. Individual political orientation is conceptualized on two dimensions: acceptance vs. rejection of social change and acceptance vs. rejection of inequality. Swedish (N = 320) and Latvian (N = 264) participants completed measures of political orientation, Social Dominance Orientation (SDO), Right Wing Authoritarianism (RWA), self vs. other orientation, tolerance for ambiguity, humanism and normativism, core political values, system justification, as well as moral foundations questionnaire and portrait values questionnaire. The results showed that the relation among the measured variables was similar in both samples. Swedish participants showed stronger endorsement of egalitarian attitudes and social values, whereas we found more self-enhancing and socially conservative values and attitudes among the Latvian participants. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

A study of MRI gradient echo signals from discrete magnetic particles with considerations of several parameters in simulations.

PubMed

Kokeny, Paul; Cheng, Yu-Chung N; Xie, He

2018-05-01

Modeling MRI signal behaviors in the presence of discrete magnetic particles is important, as magnetic particles appear in nanoparticle labeled cells, contrast agents, and other biological forms of iron. Currently, many models that take into account the discrete particle nature in a system have been used to predict magnitude signal decays in the form of R2* or R2' from one single voxel. Little work has been done for predicting phase signals. In addition, most calculations of phase signals rely on the assumption that a system containing discrete particles behaves as a continuous medium. In this work, numerical simulations are used to investigate MRI magnitude and phase signals from discrete particles, without diffusion effects. Factors such as particle size, number density, susceptibility, volume fraction, particle arrangements for their randomness, and field of view have been considered in simulations. The results are compared to either a ground truth model, theoretical work based on continuous mediums, or previous literature. Suitable parameters used to model particles in several voxels that lead to acceptable magnetic field distributions around particle surfaces and accurate MR signals are identified. The phase values as a function of echo time from a central voxel filled by particles can be significantly different from those of a continuous cubic medium. However, a completely random distribution of particles can lead to an R2' value which agrees with the prediction from the static dephasing theory. A sphere with a radius of at least 4 grid points used in simulations is found to be acceptable to generate MR signals equivalent from a larger sphere. Increasing number of particles with a fixed volume fraction in simulations reduces the resulting variance in the phase behavior, and converges to almost the same phase value for different particle numbers at each echo time. The variance of phase values is also reduced when increasing the number of particles in a fixed voxel. These results indicate that MRI signals from voxels containing discrete particles, even with a sufficient number of particles per voxel, cannot be properly modeled by a continuous medium with an equivalent susceptibility value in the voxel.

The first objective of this study was to investigate whether police violence is more tolerated when the victim is a member of a social minority (e.g., Moroccan immigrants and Romanian Gypsies in Spain) than when the victim is a member of the social majority (e.g., Spaniards). The second objective was to use Schwartz value theory to examine the moderating role of values on attitudes towards tolerance of police violence. The participants were 207 sociology and social work students from a public university in Madrid. Overall, in this study, police violence was more accepted when the victim was a member of a social minority; F(2, 206) = 77.91, p = .001, ηp 2 = 0.433, and in general, values moderated this acceptance. Thus, greater adherence to the conservation and self-promotion values subsystems would strengthen support for police violence towards a social minority member. On the other hand, greater adherence to the openness to change and self-transcendence subsystems diminish this support.

Acceptance of dying: a discourse analysis of palliative care literature.

PubMed

Zimmermann, Camilla

2012-07-01

The subject of death denial in the West has been examined extensively in the sociological literature. However, there has not been a similar examination of its "opposite", the acceptance of death. In this study, I use the qualitative method of discourse analysis to examine the use of the term "acceptance" of dying in the palliative care literature from 1970 to 2001. A Medline search was performed by combining the text words "accept or acceptance" with the subject headings "terminal care or palliative care or hospice care", and restricting the search to English language articles in clinical journals discussing acceptance of death in adults. The 40 articles were coded and analysed using a critical discourse analysis method. This paper focuses on the theme of acceptance as integral to palliative care, which had subthemes of acceptance as a goal of care, personal acceptance of healthcare workers, and acceptance as a facilitator of care. For patients and families, death acceptance is a goal that they can be helped to attain; for palliative care staff, acceptance of dying is a personal quality that is a precondition for effective practice. Acceptance not only facilitates the dying process for the patient and family, but also renders care easier. The analysis investigates the intertextuality of these themes with each other and with previous texts. From a Foucauldian perspective, I suggest that the discourse on acceptance of dying represents a productive power, which disciplines patients through apparent psychological and spiritual gratification, and encourages participation in a certain way to die.

In Defense of a Social Value Requirement for Clinical Research

PubMed Central

Wendler, David; Rid, Annette

2017-01-01

Many guidelines and commentators endorse the view that clinical research is ethically acceptable only when it has social value, in the sense of collecting data which might be used to improve health. A version of this social value requirement is included in the Declaration of Helsinki and the Nuremberg Code, and is codified in many national research regulations. At the same time, there have been no systematic analyses of why social value is an ethical requirement for clinical research. Recognizing this gap in the literature, recent articles by Alan Wertheimer and David Resnik argue that the extant justifications for the social value requirement are unpersuasive. Both authors conclude, contrary to almost all current guidelines and regulations, that it can be acceptable across a broad range of cases to conduct clinical research which is known prospectively to have no social value. The present paper assesses this conclusion by critically evaluating the ethical and policy considerations relevant to the claim that clinical research must have social value. This analysis supports the standard view that social value is an ethical requirement for the vast majority of clinical research studies and should be mandated by applicable guidelines and policies.

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.

Emotional responses to interpersonal rejection

PubMed Central

Leary, Mark R.

2015-01-01

A great deal of human emotion arises in response to real, anticipated, remembered, or imagined rejection by other people. Because acceptance by other people improved evolutionary fitness, human beings developed biopsychological mechanisms to apprise them of threats to acceptance and belonging, along with emotional systems to deal with threats to acceptance. This article examines seven emotions that often arise when people perceive that their relational value to other people is low or in potential jeopardy, including hurt feelings, jealousy, loneliness, shame, guilt, social anxiety, and embarrassment. Other emotions, such as sadness and anger, may occur during rejection episodes, but are reactions to features of the situation other than low relational value. The article discusses the evolutionary functions of rejection-related emotions, neuroscience evidence regarding the brain regions that mediate reactions to rejection, and behavioral research from social, developmental, and clinical psychology regarding psychological and behavioral concomitants of interpersonal rejection.

Introduction: Karimnagar District has consistently achieved highest rates of no-scalpel vasectomy (NSV) in the past decade when compared to state and national rates. This study was conducted to elucidate the underlying causes for higher acceptance of NSV in the district. Materials and Methods: A community-based, case control study was conducted. Sampling techniques used were purposive and simple random sampling. A semi-structured questionnaire was used to evaluate the socio-demographic, family characteristics, contraceptive history and predictors of contraceptive choice in 116 NSV acceptors and 120 other contraceptive users (OCUs). Postoperative complications and experiences were ascertained in NSV acceptors. Results: Age (χ2=11.79, P value = 0.008), literacy (χ2=17.95, P value = 0.03), duration of marriage (χ2=14.23, P value = 0.008) and number of children (χ2=10.45, P value = 0.01) were significant for acceptance of NSV. Among the predictors, method suggested by peer/ health worker (OR = 1.5, P value = 0.01), method does not require regular intervention (OR = 1.3, P value = 0.004) and permanence of the method (OR = 1.2, P value = 0.031) were significant. Acceptors were most satisfied with the shorter duration required to return to work and the most common complication was persistent postoperative pain among 12 (10.34%) of the acceptors. Conclusion: Advocating and implementing family planning is of high significance in view of the population growth in India and drawing from the demographic profile, predictors, pool of trainers and experiences in Karimnagar District, a similar achievement of higher rates of this simple procedure with few complications can be replicated.

Although prisons have been noted as important venues for HIV testing, few studies have explored the factors within this context that may influence HIV test acceptance. Moreover, there is a dearth of research related to HIV and incarcerated populations in middle and low-income countries, where both the burden of HIV and the number of people incarcerated is higher compared to high-income countries. This study explores the relationship between HIV coping self-efficacy, HIV-related stigma, and HIV test acceptance in the largest prisons in Jamaica. A random sample of inmates (n=298) recruited from an HIV testing demonstration project were asked to complete a cross-sectional quantitative survey. Participants who reported high HIV coping self-efficacy (adjusted odds ratio (AOR) 1.86: 95% confidence interval CI 1.24-2.78, p-value=0.003), some perceived risk of HIV (AOR 2.51: 95% (CI) 1.57-4.01, p-value=0.000), and low HIV testing stigma (AOR 1.71: 95% CI 1.05-2.79, p-value=0.032) were more likely to test for HIV. Correlates of HIV coping self-efficacy included external and internal HIV stigma (AOR 1.28: 95% CI 1.25-1.32, p-value=0.000 and AOR 1.76: 95% CI 1.34-2.30, p-value=0.000, respectively), social support (AOR 2.09: 95% CI 1.19-3.68, p-value=0.010), and HIV knowledge (AOR 2.33: 95% CI 1.04-5.22, p-value=0.040). Policy and programs should focus on the interrelationships of these constructs to increase participation in HIV testing in prison.

High-Speed Research: Sonic Boom, Volume 1

NASA Technical Reports Server (NTRS)

Edwards, Thomas A. (Editor)

1994-01-01

The second High-Speed Research Program Sonic Boom Workshop was held at NASA Ames Research Center May 12-14, 1993. The workshop was organized into three sessions dealing with atmospheric propagation, acceptability, and configuration design. Volume 1 includes papers on atmospheric propagation and acceptability studies. Significant progress is noted in these areas in the time since the previous workshop a year earlier. In particular, several papers demonstrate an improved capability to model the effect of atmospheric turbulence on sonic booms. This is a key issue in determining the stability and acceptability of shaped sonic booms. In the area of acceptability, the PLdB metric has withstood considerable scrutiny and is validated as a loudness metric for a wide variety of sonic boom shapes. The differential loudness of asymmetric sonic booms is better understood, too.

Self-acceptance of stuttering: A preliminary study.

PubMed

De Nardo, Thales; Gabel, Rodney M; Tetnowski, John A; Swartz, Eric R

2016-01-01

This study explored the relationship between self-acceptance of stuttering and (1) psychosocial factors (self-esteem, hostility towards others, emotional support, and perceived discrimination); (2) treatment history (support group participation, therapy duration, and perceived therapy success); and (3) previously reported variables in self-acceptance of stuttering, which include age and stuttering severity. Participants were 80 adults who stutter who were recruited with assistance from the National Stuttering Association and Board Certified Specialists in Fluency Disorders. Participants completed an electronic survey composed of an acceptance of stuttering scale, psychosocial scales, and a participant information questionnaire. Statistical analysis identified significant correlations between participants' reports of self-acceptance of stuttering and self-esteem, perceived discrimination, hostility towards others, and perceived therapy outcome. Self-esteem was positively correlated with self-acceptance, while hostility towards others and perceived discrimination was negatively correlated with self-acceptance. Participants who perceived their therapy outcome to be successful were significantly more likely to report higher levels of self-acceptance. No significant relationships were found between self-acceptance of stuttering and support group participation, emotional support, stuttering severity, and participant age. This exploratory investigation has provided a foundation for future studies on the self-acceptance of stuttering. The findings indicate common psychosocial variables in self-acceptance of stuttering and of other disabilities. The significant relationships between self-acceptance of stuttering and psychosocial and therapeutic variables found need to be further explored to identify its causalities and clinical implications. The reader will be able to (1) discuss the importance of assessing self-acceptance of stuttering, (2) summarize the literature on self-acceptance of disability, and (3) describe the significant findings related to self-acceptance of stuttering and psychosocial, therapeutic variables.

Williamson, Brittany; Aplin, Tammy; de Jonge, Desleigh; Goyne, Matthew

2017-11-01

To explore the acceptability and value of three wearable GPS devices for older persons and individuals with a disability and safety concerns when accessing the community. This pilot study explored six wearers' and their support persons' experience of using three different wearable GPS devices (a pendant, watch, and mini GPS phone), each for a two-week period. Participants identified safety as the main value of using a wearable GPS device. The acceptability and value of these devices was strongly influenced by device features, ease of use, cost, appearance, the reliability of the GPS coordinates, the wearer's health condition and the users familiarity with technology. Overall, participants indicated that they preferred the pendant. Wearable GPS devices are potentially useful in providing individuals who have safety concerns with reassurance and access to assistance as required. To ensure successful utilization, future device design and device selection should consider the user's familiarity with technology and their health condition. This study also revealed that not all wearable GPS devices provide continuous location tracking. It is therefore critical to ensure that the device's location tracking functions address the wearer's requirements and reason for using the device. Implications for Rehabilitation The acceptability and usability of wearable GPS devices is strongly influenced by the device features, ease of use, cost, appearance, the reliability of the device to provide accurate and timely GPS coordinates, as well as the health condition of the wearer and their familiarity with technology. Wearable GPS devices need to be simple to use and support and training is essential to ensure they are successfully utilized. Not all wearable GPS devices provide continuous location tracking and accuracy of location is impacted by line of sight to satellites. Therefore, care needs to be taken when choosing a suitable device, to ensure that the device's location tracking features are based on the wearer's requirements and value behind using the device.

Text recycling: acceptable or misconduct?

PubMed

Harriman, Stephanie; Patel, Jigisha

2014-08-16

Text recycling, also referred to as self-plagiarism, is the reproduction of an author's own text from a previous publication in a new publication. Opinions on the acceptability of this practice vary, with some viewing it as acceptable and efficient, and others as misleading and unacceptable. In light of the lack of consensus, journal editors often have difficulty deciding how to act upon the discovery of text recycling. In response to these difficulties, we have created a set of guidelines for journal editors on how to deal with text recycling. In this editorial, we discuss some of the challenges of developing these guidelines, and how authors can avoid undisclosed text recycling.

Paying less but harvesting more: the effect of unconscious acceptance in regulating frustrating emotion.

PubMed

Ding, NanXiang; Yang, JieMin; Liu, YingYing; Yuan, JiaJin

2015-08-01

Previous studies indicate that emotion regulation may occur unconsciously, without the cost of cognitive effort, while conscious acceptance may enhance negative experiences despite having potential long-term health benefits. Thus, it is important to overcome this weakness to boost the efficacy of the acceptance strategy in negative emotion regulation. As unconscious regulation occurs with little cost of cognitive resources, the current study hypothesizes that unconscious acceptance regulates the emotional consequence of negative events more effectively than does conscious acceptance. Subjects were randomly assigned to conscious acceptance, unconscious acceptance and no-regulation conditions. A frustrating arithmetic task was used to induce negative emotion. Emotional experiences were assessed on the Positive Affect and Negative Affect Scale while emotion- related physiological activation was assessed by heart-rate reactivity. Results showed that conscious acceptance had a significant negative affective consequence, which was absent during unconscious acceptance. That is, unconscious acceptance was linked with little reduction of positive affect during the experience of frustration, while this reduction was prominent in the control and conscious acceptance groups. Instructed, conscious acceptance resulted in a greater reduction of positive affect than found for the control group. In addition, both conscious and unconscious acceptance strategies significantly decreased emotion-related heart-rate activity (to a similar extent) in comparison with the control condition. Moreover, heart-rate reactivity was positively correlated with negative affect and negatively correlated with positive affect during the frustration phase relative to the baseline phase, in both the control and unconscious acceptance groups. Thus, unconscious acceptance not only reduces emotion-related physiological activity but also better protects mood stability compared with conscious acceptance. This suggests that the clinical practice of acceptance therapy may need to consider using the unconscious priming of an accepting attitude, instead of intentionally instructing people to implement such a strategy, to boost the efficacy of acceptance in emotion regulation.

Relationship between colorimetric (instrumental) evaluation and consumer-defined beef colour acceptability.

2016-11-01

The relationship between instrumental colorimetric values (L*, a*, b*, the ratio of reflectance at 630nm and 580nm) and consumer perception of acceptable beef colour was evaluated using a web-based survey and standardised photographs of beef m. longissimus lumborum with known colorimetrics. Only L* and b* were found to relate to average consumer opinions of beef colour acceptability. Respondent nationality was also identified as a source of variation in beef colour acceptability score. Although this is a preliminary study with the findings necessitating additional investigation, these results suggest L* and b* as candidates for developing instrumental thresholds for consumer beef colour expectations.

Effective interventions promoting healthier eating behavior among adolescents are urgently needed. One factor that has been shown to impact effectiveness is whether the target population accepts the intervention. While previous research has assessed adults' acceptance of eating-related interventions, research on the opinion of adolescents is lacking. The current study addressed this gap in the literature. Two thousand seven hundred sixty four adolescents (aged 10-17 years) from four European countries answered questions about individual characteristics (socio-demographics, anthropometrics, and average daily intake of healthy and unhealthy foods) and the acceptability of ten eating-related intervention strategies. These strategies varied in type (either promoting healthy eating or discouraging unhealthy eating), level of intrusiveness, setting (home, school, broader out-of-home environment), and change agent (parents, teacher, policy makers). Based on adolescents' acceptability ratings, strategies could be clustered into two categories, those promoting healthy eating and those discouraging unhealthy eating, with acceptability rated significantly higher for the former. Acceptability of intervention strategies was rated moderate on average, but higher among girls, younger, overweight and immigrant adolescents, and those reporting healthier eating. Polish and Portuguese adolescents were overall more accepting of strategies than UK and Dutch adolescents. Adolescents preferred intervention strategies that promote healthy eating over strategies that discourage unhealthy eating. Level of intrusiveness affected acceptability ratings for the latter type of strategies only. Various individual and behavioral characteristics were associated with acceptability. These findings provide practical guidance for the selection of acceptable intervention strategies to improve adolescents' eating behavior.

The calibration of plane parallel ionisation chambers for the measurement of absorbed dose in electron beams of low to medium energies. Part 2: The PTW/MARKUS chamber.

PubMed

Cross, P; Freeman, N

1997-06-01

The purpose of Part 2 study of calibration methods for plane parallel ionisation chambers was to determine the feasibility of using beams of calibration of the MARKUS chamber other than the standard AAPM TG39 reference beams of 60Co and a high energy electron beam (E0 > or = 15 MeV). A previous study of the NACP chamber had demonstrated an acceptable level of accuracy with corresponding spread of -0.5% to +0.8% for its calibration in non-standard situations (medium to low energy electron and photon beams). For non-standard situations the spread in NDMARKUS values was found to be +/-2.5%. The results suggest that user calibrations of the MARKUS chamber in non-standard situations are associated with more uncertainties than is the case with the NACP chamber.

Precise knowledge of the fundamental properties of the proton is essential for our understanding of atomic structure as well as for precise tests of fundamental symmetries. We report on a direct high-precision measurement of the magnetic moment μ p of the proton in units of the nuclear magneton μ N The result, μ p = 2.79284734462 (±0.00000000082) μ N , has a fractional precision of 0.3 parts per billion, improves the previous best measurement by a factor of 11, and is consistent with the currently accepted value. This was achieved with the use of an optimized double-Penning trap technique. Provided a similar measurement of the antiproton magnetic moment can be performed, this result will enable a test of the fundamental symmetry between matter and antimatter in the baryonic sector at the 10 -10 level.

Social interaction anxiety and the discounting of positive interpersonal events.

PubMed

Vassilopoulos, Stephanos P; Banerjee, Robin

2010-10-01

Recent research has indicated that individuals with social interaction anxiety make biased interpretations of positive social interactions, with greater general apprehension in response to such events and more negative predictions about the future. There has also been some preliminary evidence for a second facet of interpretation bias, namely a failure to accept others' positive reactions at face value, but this has so far not been adequately studied. The present study developed a new measure of this "discounting" dimension and utilized a nonclinical sample of undergraduate students to provide an initial analysis of the scale. Results provide early support for the psychometric properties of our scale, and indicate that discounting mediates the relationship between social interaction anxiety and low positive affect, over and above the previously studied aspect of positive event interpretation bias. The implications for treatment interventions and further research are discussed.

Determining fundamental properties of matter created in ultrarelativistic heavy-ion collisions

NASA Astrophysics Data System (ADS)

2014-03-01

Posterior distributions for physical parameters describing relativistic heavy-ion collisions, such as the viscosity of the quark-gluon plasma, are extracted through a comparison of hydrodynamic-based transport models to experimental results from 100AGeV+100AGeV Au +Au collisions at the Relativistic Heavy Ion Collider. By simultaneously varying six parameters and by evaluating several classes of observables, we are able to explore the complex intertwined dependencies of observables on model parameters. The methods provide a full multidimensional posterior distribution for the model output, including a range of acceptable values for each parameter, and reveal correlations between them. The breadth of observables and the number of parameters considered here go beyond previous studies in this field. The statistical tools, which are based upon Gaussian process emulators, are tested in detail and should be extendable to larger data sets and a higher number of parameters.

The law of diminishing returns in clinical medicine: how much risk reduction is enough?

PubMed

Mold, James W; Hamm, Robert M; McCarthy, Laine H

2010-01-01

The law of diminishing returns, first described by economists to explain why, beyond a certain point, additional inputs produce smaller and smaller outputs, offers insight into many situations encountered in clinical medicine. For example, when the risk of an adverse event can be reduced in several different ways, the impact of each intervention can generally be shown mathematically to be reduced by the previous ones. The diminishing value of successive interventions is further reduced by adverse consequences (eg, drug-drug, drug-disease, and drug-nutrient interactions), as well as by the total expenditures of time, energy, and resources, which increase with each additional intervention. It is therefore important to try to prioritize interventions based on patient-centered goals and the relative impact and acceptability of the interventions. We believe that this has implications for clinical practice, research, and policy.

Women's experiences of coping with pregnancy termination for fetal abnormality.

PubMed

Lafarge, Caroline; Mitchell, Kathryn; Fox, Pauline

2013-07-01

Pregnancy termination for fetal abnormality (TFA) can have significant psychological consequences. Most previous research has been focused on measuring the psychological outcomes of TFA, and little is known about the coping strategies involved. In this article, we report on women's coping strategies used during and after the procedure. Our account is based on experiences of 27 women who completed an online survey. We analyzed the data using interpretative phenomenological analysis. Coping comprised four structures, consistent across time points: support, acceptance, avoidance, and meaning attribution. Women mostly used adaptive coping strategies but reported inadequacies in aftercare, which challenged their resources. The study's findings indicate the need to provide sensitive, nondirective care rooted in the acknowledgment of the unique nature of TFA. Enabling women to reciprocate for emotional support, promoting adaptive coping strategies, highlighting the potential value of spending time with the baby, and providing long-term support (including during subsequent pregnancies) might promote psychological adjustment to TFA.

Statistics of equivalent width data and new oscillator strengths for Si II, Fe II, and Mn II. [in interstellar medium

NASA Technical Reports Server (NTRS)

Van Buren, Dave

1986-01-01

Equivalent width data from Copernicus and IUE appear to have an exponential, rather than a Gaussian distribution of errors. This is probably because there is one dominant source of error: the assignment of the background continuum shape. The maximum likelihood method of parameter estimation is presented for the case of exponential statistics, in enough generality for application to many problems. The method is applied to global fitting of Si II, Fe II, and Mn II oscillator strengths and interstellar gas parameters along many lines of sight. The new values agree in general with previous determinations but are usually much more tightly constrained. Finally, it is shown that care must be taken in deriving acceptable regions of parameter space because the probability contours are not generally ellipses whose axes are parallel to the coordinate axes.

Mixed integer nonlinear programming model of wireless pricing scheme with QoS attribute of bandwidth and end-to-end delay

NASA Astrophysics Data System (ADS)

Irmeilyana, Puspita, Fitri Maya; Indrawati

2016-02-01

The pricing for wireless networks is developed by considering linearity factors, elasticity price and price factors. Mixed Integer Nonlinear Programming of wireless pricing model is proposed as the nonlinear programming problem that can be solved optimally using LINGO 13.0. The solutions are expected to give some information about the connections between the acceptance factor and the price. Previous model worked on the model that focuses on bandwidth as the QoS attribute. The models attempt to maximize the total price for a connection based on QoS parameter. The QoS attributes used will be the bandwidth and the end to end delay that affect the traffic. The maximum goal to maximum price is achieved when the provider determine the requirement for the increment or decrement of price change due to QoS change and amount of QoS value.

Failure to rapidly identify high-value information due to inappropriate output may alter user acceptance and satisfaction. The information needs for different intensive care unit (ICU) providers are not the same. This can obstruct successful implementation of electronic medical record (EMR) systems. We evaluated the implementation experience and satisfaction of providers using a novel EMR interface-based on the information needs of ICU providers-in the context of an existing EMR system. This before-after study was performed in the ICU setting at two tertiary care hospitals from October 2013 through November 2014. Surveys were delivered to ICU providers before and after implementation of the novel EMR interface. Overall satisfaction and acceptance was reported for both interfaces. A total of 246 before (existing EMR) and 115 after (existing EMR+novel EMR interface) surveys were analyzed. 14% of respondents were prescribers and 86% were non-prescribers. Non-prescribers were more satisfied with the existing EMR, whereas prescribers were more satisfied with the novel EMR interface. Both groups reported easier data gathering, routine tasks & rounding, and fostering of team work with the novel EMR interface. This interface was the primary tool for 18% of respondents after implementation and 73% of respondents intended to use it further. Non-prescribers reported an intention to use this novel interface as their primary tool for information gathering. Compliance and acceptance of new system is not related to previous duration of work in ICU, but ameliorates with the length of EMR interface usage. Task-specific and role-specific considerations are necessary for design and successful implementation of a EMR interface. The difference in user workflows causes disparity of the way of EMR data usage. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Testing for acute fish toxicity is an integral part of the environmental safety assessment of chemicals. A true replacement of primary fish tissue was recently proposed using cell viability in a fish gill cell line (RTgill-W1) as a means of predicting acute toxicity, showing good predictivity on 35 chemicals. To promote regulatory acceptance, the predictivity and applicability domain of novel tests need to be carefully evaluated on chemicals with existing high-quality in vivo data. We applied the RTgill-W1 cell assay to 38 fragrance chemicals with a wide range of both physicochemical properties and median lethal concentration (LC50) values and representing a diverse range of chemistries. A strong correlation (R 2  = 0.90-0.94) between the logarithmic in vivo LC50 values, based on fish mortality, and the logarithmic in vitro median effect concentration (EC50) values based on cell viability was observed. A leave-one-out analysis illustrates a median under-/overprediction from in vitro EC50 values to in vivo LC50 values by a factor of 1.5. This assay offers a simple, accurate, and reliable alternative to in vivo acute fish toxicity testing for chemicals, presumably acting mainly by a narcotic mode of action. Furthermore, the present study provides validation of the predictivity of the RTgill-W1 assay on a completely independent set of chemicals that had not been previously tested and indicates that fragrance chemicals are clearly within the applicability domain.

The feasibility and acceptability of teaching medical students to use PDA clinical decision support tools via a Web-based course have not been previously evaluated. A total of 119 third-year family medicine clerkship students completed a baseline survey on PDA use, attended an introductory PDA lecture, and were invited to voluntarily access a Web-based course through Blackboard. All students had been previously issued with PDAs in their second year. At baseline, 95% of students reported having removed their PDA from its box, 59% reported using it weekly, and 71% had loaded medical applications. From August 2006--March 2007, 36 students accessed the course 610 times (range 8-54). The PDA cases comprised 63% of hits, course resources 30% of hits, and course information 6% of hits. Students evaluated the course equally to other clerkship didactics. It is feasible and acceptable to students to teach PDA decision support tools in an online course. In our setting, for the minority of students who chose to learn online, the format was successful and met their needs.

A new approach in psychotherapy: ACT (acceptance and commitment therapy).

PubMed

McHugh, Louise

2011-09-01

Acceptance and commitment therapy (ACT) focuses on enhancing psychological flexibility in the service of achieving core life values. One thing that distinguishes ACT from other psychotherapies is its grounding in empirical behavioural science. The results of the latter suggest that the capacity for human language can produce seriously negative psychological effects under certain circumstances. ACT is a therapeutic approach in which the negative effects of human language are undermined so as to support flexible values based living. ACT therapeutic work involves six key processes proposed under the "hexaflex" model. ACT has received considerable empirical support at a number of different levels of analysis.

The regulatory function of self-esteem: testing the epistemic and acceptance signaling systems.

The authors draw on sociometer theory (e.g., Leary, 2004) and self-verification theory (e.g., Swann, 1997) to propose an expanded model of the regulatory function of self-esteem. The model suggests that people not only possess an acceptance signaling system that indicates whether relational value is high or low but also possess an epistemic signaling system that indicates whether social feedback is consistent or inconsistent with chronic perceived relational value (i.e., global self-esteem). One correlational study and 5 experiments, with diverse operationalizations of social feedback, demonstrated that the epistemic signaling system responds to self-esteem consistent or inconsistent relational-value feedback with increases or deceases in epistemic certainty. Moreover, Studies 3-6 demonstrated that the acceptance and epistemic signaling systems respond uniquely to social feedback. Finally, Studies 5 and 6 provide evidence that the epistemic signaling system is part of a broader self-regulatory system: Self-esteem inconsistent feedback caused cognitive efforts to decrease the discrepancy between self-views and feedback and caused depleted self-regulatory capacity on a subsequent self-control task.

Most cost-effective concentrated photovoltaics (CPV) systems are based on an optical train comprising two stages, the first being a Fresnel lens. Among them, the Fresnel-Köhler (FK) concentrator stands out owing to both performance and practical reasons. We describe the experimental measurements procedure for FK concentrator modules. This procedure includes three main types of measurements: electrical efficiency, acceptance angle, and irradiance uniformity at the solar cell plane. We have collected here the performance features of two different FK prototypes (ranging different f-numbers, concentration ratios, and cell sizes). The electrical efficiencies measured in both prototypes are high and fit well with the models, achieving values up to 32.7% (temperature corrected, and with no antireflective coating on SOE or POE surfaces) in the best case. The measured angular transmission curves show large acceptance angles, again perfectly matching the expected values [measured concentration acceptance product (CAP) values over 0.56]. The irradiance pattern on the cell (obtained with a digital camera) shows an almost perfectly uniform distribution, as predicted by raytrace simulations. All these excellent on-sun results confirm the FK concentrator as a potentially cost-effective solution for the CPV market.

Tissue viability imaging: microvascular response to vasoactive drugs induced by iontophoresis.

When one is studying the physiology of the cutaneous microcirculation there is a need for relevant non-invasive and versatile techniques. In this study we used a new optical device, the tissue viability imager (TiVi), to map changes in cutaneous microvascular concentrations of red blood cells during iontophoresis of vasoactive substances (noradrenaline (NA) and phenylephrine (Phe) for vasoconstriction and acetylcholine (ACh) and sodium nitroprusside (SNP) for vasodilatation). We aimed to present data both individually and pooled, using a four-variable logistic dose response model that is commonly used in similar in vitro vascular studies. The accuracy of the TiVi was also investigated by calculating the coefficient of variation and comparing it with similar tests previously done using laser Doppler imaging. Tests were also performed using the TiVi and LDPI simultaneously to further compare the two methods. Results showed that the TiVi is capable of quantifying vascular responses to iontophorised noradrenaline and phenylephrine without the need to increase background flow first. Fitting the TiVi data to the dose response model resulted in ED(50)-values with narrow confidence intervals and acceptable r(2) values. Mean ED(50)-values for the TiVi did not differ significantly from similar values obtained using laser Doppler. Results further seem to suggest that when the blood perfusion increases during vasodilatation in skin the initial phase relies mainly on an increase in red blood cell concentration whereas the further perfusion increase is due to an increase in red blood cell velocity.

Lateralised sleep spindles relate to false memory generation.

PubMed

Shaw, John J; Monaghan, Padraic

2017-12-01

Sleep is known to enhance false memories: After presenting participants with lists of semantically related words, sleeping before recalling these words results in a greater acceptance of unseen "lure" words related in theme to previously seen words. Furthermore, the right hemisphere (RH) seems to be more prone to false memories than the left hemisphere (LH). In the current study, we investigated the sleep architecture associated with these false memory and lateralisation effects in a nap study. Participants viewed lists of related words, then stayed awake or slept for approximately 90min, and were then tested for recognition of previously seen-old, unseen-new, or unseen-lure words presented either to the LH or RH. Sleep increased acceptance of unseen-lure words as previously seen compared to the wake group, particularly for RH presentations of word lists. RH lateralised stage 2 sleep spindle density relative to the LH correlated with this increase in false memories, suggesting that RH sleep spindles enhanced false memories in the RH.

Effect of flaxseed flour incorporation on the physical properties and consumer acceptability of cereal bars.

PubMed

Khouryieh, H; Aramouni, F

2013-12-01

Extensive research has revealed numerous nutritional and health benefits of flaxseed due primarily to its nutrients content. The objective of this study was to evaluate the effect of flaxseed flour addition on the physical and sensory characteristics of cereal bars. Four formulations of the flaxseed cereal bars were prepared by partially replacing oats with flaxseed flour added at levels of 0 (control), 6%, 12% and 18%. There were no significant differences (p > 0.05) in water activity, moisture and firmness values between the flaxseed bars and control. Flaxseed addition significantly (p < 0.05) decreased lightness and increased redness of the bars. There were no significant differences (p > 0.05) between the 12% flax cereal bars and the control with respect to sensory attributes and overall acceptability. The overall acceptability for both 12% flax bars and the control was in between 'like moderately' and 'like slightly' on the 9-point hedonic scale. The overall acceptability was most highly correlated with flavor acceptability for both control (r = 0.80) and 12% flax (r = 0.82) cereal bars. Flaxseed bars provided 12% dietary fiber of the daily recommended value. These results indicated that flaxseed flour incorporation up to 12% substantially enhanced the nutritional qualities of the cereal bars without affecting their sensory and quality properties.

[Acceptance and Commitment Therapy in the Treatment of Chronic Disease].

PubMed

Kuba, Katharina; Weißflog, Gregor

2017-12-01

Acceptance and Commitment Therapy (ACT) is an intervention representing a transdiagnostic and contextual approach that assumes that psychological suffering is caused by experiential avoidance. The primary intention of ACT is not to eliminate symptoms and to treat mental disorders. Instead, ACT aims to increase psychological flexibility, i. e. to broaden the repertoire of cognitions and behaviors when facing inner and outer aversive events or experiences. Psychological flexibility can be enhanced by working with the 6 core components of the ACT model. Experience-focused methods like metaphors and exercises for acceptance play a crucial role in the therapeutic work. In short, with ACT patients can learn: ▪ that rigid and inflexible attempts to fight aversive experience are problematic ▪ a mindful experience of inner and outer experience ▪ to differentiate between unchangeable and changeable events (acceptance) ▪ to identify values or respectively life goals and to behave in a way that is consistent with them (commitment)The therapeutic focus of ACT is to create a balance between acceptance and behavioral change consistent with chosen values. Chronic diseases are often associated with aversive inner and outer experiences. A growing number of studies support the efficacy of ACT. There is evidence that ACT can increase psychological flexibility and potentially also lead to better self-management within the context of chronic somatic diseases. © Georg Thieme Verlag KG Stuttgart · New York.

Acceptance and Commitment Therapy modules: Differential impact on treatment processes and outcomes.

Villatte, Jennifer L; Vilardaga, Roger; Villatte, Matthieu; Plumb Vilardaga, Jennifer C; Atkins, David C; Hayes, Steven C

2016-02-01

A modular, transdiagnostic approach to treatment design and implementation may increase the public health impact of evidence-based psychosocial interventions. Such an approach relies on algorithms for selecting and implementing treatment components intended to have a specific therapeutic effect, yet there is little evidence for how components function independent of their treatment packages when employed in clinical service settings. This study aimed to demonstrate the specificity of treatment effects for two components of Acceptance and Commitment Therapy (ACT), a promising candidate for modularization. A randomized, nonconcurrent, multiple-baseline across participants design was used to examine component effects on treatment processes and outcomes in 15 adults seeking mental health treatment. The ACT OPEN module targeted acceptance and cognitive defusion; the ACT ENGAGED module targeted values-based activation and persistence. According to Tau-U analyses, both modules produced significant improvements in psychiatric symptoms, quality of life, and targeted therapeutic processes. ACT ENGAGED demonstrated greater improvements in quality of life and values-based activation. ACT OPEN showed greater improvements in symptom severity, acceptance, and defusion. Both modules improved awareness and non-reactivity, which were mutually targeted, though using distinct intervention procedures. Both interventions demonstrated high treatment acceptability, completion, and patient satisfaction. Treatment effects were maintained at 3-month follow up. ACT components should be considered for inclusion in a modular approach to implementing evidence-based psychosocial interventions for adults. Copyright © 2015 Elsevier Ltd. All rights reserved.

This pilot trial investigated the short and long-term effects of Acceptance Training (ACT) intervention on acceptance, perceived health, functional status, anxiety, and depression in elders with chronic conditions living in retirement communities (RCs). The ACT intervention combined Rational Emotive Behavior Therapy with music, relaxation, and guided imagery during six weekly 2-hour sessions. Face-to-face interviews were conducted with 16 African-American and 46 White elders across four data collection points in six randomly selected RCs using well-established measures of perceived health, functional status, anxiety, and depression, and a measure of acceptance of chronic conditions adapted from a previous measure of acceptance of diabetes. While changes were found in perceived health, functional status, anxiety, and depression, the most significant changes occurred in the elders' acceptance of chronic conditions immediately after the intervention (t = -2.62, p < .02), and these changes persisted for 6 and 12 weeks (t's = -2.74, -3.32, p's < .01), respectively. Although a 40% attrition rate reduced the sample size from 62 (N = 62) to 37 (N = 37), the significant increases in acceptance over time provide initial evidence for the fidelity of the ACT intervention.

Objectives. We assessed whether an intervention based on acceptance and commitment therapy (ACT) and mindfulness was successful in promoting positive mental health by enhancing psychological flexibility. Methods. Participants were 93 adults with mild to moderate psychological distress. They were randomly assigned to the group intervention (n = 49) or to a waiting-list control group (n = 44). Participants completed measures before and after the intervention as well as 3 months later at follow-up to assess mental health in terms of emotional, psychological, and social well-being (Mental Health Continuum–Short Form) as well as psychological flexibility (i.e., acceptance of present experiences and value-based behavior, Acceptance and Action Questionnaire-II). Results. Regression analyses showed that compared with the participants on the waiting list, participants in the ACT and mindfulness intervention had greater emotional and psychological well-being after the intervention and also greater psychological flexibility at follow-up. Mediational analyses showed that the enhancement of psychological flexibility during the intervention mediated the effects of the intervention on positive mental health. Conclusions. The intervention is effective in improving positive mental health by stimulating skills of acceptance and value-based action. PMID:20966360

Two interforaminal dental implants in is a common treatment option for denture retention in edentulous patients. Economic methods to assess the patient's quality of life include the willingness to pay (WTP) for implant treatment and willingness to accept (WTA) to forgo implant treatment. The purpose of this study was to assess the monetary value of implant retained complete dentures using WTP and WTA. We included a convenience sample of 16 patients from a previously published cohort study on the survival of immediately loaded implants in edentulous patients to assess WTP and WTA for this treatment option. The average maximum WTP for implant treatment was 4606 (95% CI: 2991-6222) Swiss Francs. Out of the 16 patients, only 5 were willing to trade their implants for money, with a mean WTA of CHF 33'500 (range: 3000-100'000).All patients would agree to undergo the implant surgery procedure again. The results of the present study show that most patients are not willing to trade the increase in quality of life after implant surgery against money, suggesting that WTA exceeds by large WTP for the same health condition.

An electrical analogy relating the Atlantic multidecadal oscillation to the Atlantic meridional overturning circulation.

PubMed

Kurtz, Bruce E

2014-01-01

The Atlantic meridional overturning circulation (AMOC) is the northward flow of surface water to subpolar latitudes where deepwater is formed, balanced by southward abyssal flow and upwelling in the vicinity of the Southern Ocean. It is generally accepted that AMOC flow oscillates with a period of 60-80 years, creating a regular variation in North Atlantic sea surface temperature known as the Atlantic multidecadal oscillation (AMO). This article attempts to answer two questions: how is the AMOC driven and why does it oscillate? Using methods commonly employed by chemical engineers for analyzing processes involving flowing liquids, apparently not previously applied to trying to understand the AMOC, an equation is developed for AMOC flow as a function of the meridional density gradient or the corresponding temperature gradient. The equation is based on the similarity between the AMOC and an industrial thermosyphon loop cooler, which circulates a heat transfer liquid without using a mechanical pump. Extending this equation with an analogy between the flow of heat and electricity explains why the AMOC flow oscillates and what determines its period. Calculated values for AMOC flow and AMO oscillation period are in good agreement with measured values.

2017-06-01

To extend the evidence on the reliability and construct validity of the Five-Factor Model Rating Form (FFMRF) in its self-report version, two independent samples of Italian participants, which were composed of 510 adolescent high school students and 457 community-dwelling adults, respectively, were administered the FFMRF in its Italian translation. Adolescent participants were also administered the Italian translation of the Borderline Personality Features Scale for Children-11 (BPFSC-11), whereas adult participants were administered the Italian translation of the Triarchic Psychopathy Measure (TriPM). Cronbach α values were consistent with previous findings; in both samples, average interitem r values indicated acceptable internal consistency for all FFMRF scales. A multidimensional graded item response theory model indicated that the majority of FFMRF items had adequate discrimination parameters; information indices supported the reliability of the FFMRF scales. Both categorical (i.e., item-level) and scale-level regression analyses suggested that the FFMRF scores may predict a nonnegligible amount of variance in the BPFSC-11 total score in adolescent participants, and in the TriPM scale scores in adult participants.

Previous studies indicate that prostate cancer antigen 3 (PCA3) is highly expressed in prostatic tumors. However, its clinical value has not been characterized. The aim of this study was to investigate the clinical value of the urine PCA3 test in the diagnosis of prostate cancer by pooling the published data. Clinical trials utilizing the urine PCA3 test for diagnosing prostate cancer were retrieved from PubMed and Embase. A total of 46 clinical trials including 12,295 subjects were included in this meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR), diagnostic odds ratio (DOR) and area under the curve (AUC) were 0.65 (95% confidence interval [CI]: 0.63-0.66), 0.73 (95% CI: 0.72-0.74), 2.23 (95% CI: 1.91-2.62), 0.48 (95% CI: 0.44-0.52), 5.31 (95% CI: 4.19-6.73) and 0.75 (95% CI: 0.74-0.77), respectively. In conclusion, the urine PCA3 test has acceptable sensitivity and specificity for the diagnosis of prostate cancer and can be used as a non-invasive method for that purpose.

To validate the SQLS scale in Colombian patients diagnosed with schizophrenia. The self-report scale was applied to 251 patients. Measures of test-retest reliability, internal consistency and correlation inter-scales with the SF-12 were made by applying the scale 2 days later in 28 patients, and 30 days later in 38; 50 patients filled-out the SF-12 scale to determine the concurrent validity. Three domains were found with all of them having Cronbach's alphas >0.7. The three factors model did not show adequate fit indexes. Test-retest evaluation showed satisfactory correlation values (>0.86). Sensitivity to change did not shown significant differences between the repeated measures. As regards concurrent validity, acceptable correlation values were found only in SF-12 domains related to mental health and functioning. The SQLS has a factorial structure consistent with previous reports, adequate internal consistency and temporal stability. However, a more detailed examination of some of these items is required, considering that the measurement of the construct does not appear to be adequate.

SenseCam: A new tool for memory rehabilitation?

PubMed

Dubourg, L; Silva, A R; Fitamen, C; Moulin, C J A; Souchay, C

2016-12-01

The emergence of life-logging technologies has led neuropsychologist to focus on understanding how this new technology could help patients with memory disorders. Despite the growing number of studies using life-logging technologies, a theoretical framework supporting its effectiveness is lacking. This review focuses on the use of life-logging in the context of memory rehabilitation, particularly the use of SenseCam, a wearable camera allowing passive image capture. In our opinion, reviewing SenseCam images can be effective for memory rehabilitation only if it provides more than an assessment of prior occurrence in ways that reinstates previous thoughts, feelings and sensory information, thus stimulating recollection. Considering the fact that, in memory impairment, self-initiated processes are impaired, we propose that the environmental support hypothesis can explain the value of SenseCam for memory retrieval. Twenty-five research studies were selected for this review and despite the general acceptance of the value of SenseCam as a memory technique, only a small number of studies focused on recollection. We discuss the usability of this tool to improve episodic memory and in particular, recollection. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Target and beam-target spin asymmetries in exclusive pion electroproduction for Q 2 > 1 GeV 2 . II. e p → e π 0 p

Beam-target double-spin asymmetries and target single-spin asymmetries were measured for the exclusive π + electroproduction reaction γ*p→nπ +. The results were obtained from scattering of 6-GeV longitudinally polarized electrons off longitudinally polarized protons using the CEBAF Large Acceptance Spectrometer at Jefferson Laboratory. The kinematic range covered is 1.1 < W < 3 GeV and 1 < Q 2 < 6GeV 2. Results were obtained for about 6000 bins in W, Q 2, cos(θ*), and Φ*. Except at forward angles, very large target-spin asymmetries are observed over the entire W region. Reasonable agreement is found with phenomenological fits to previous datamore » for W < 1.6 GeV, but very large differences are seen at higher values of W. A generalized parton distributions (GPD)-based model is in poor agreement with the data. As a result, when combined with cross-sectional measurements, the present results provide powerful constraints on nucleon resonance amplitudes at moderate and large values of Q 2, for resonances with masses as high as 2.4 GeV.« less

Molecular recognition is of paramount interest in many applications. Here we investigate a series of host-guest systems previously used in the SAMPL4 blind challenge by using molecular simulations and the AMOEBA polarizable force field. The free energy results computed by Bennett's acceptance ratio (BAR) method using the AMOEBA polarizable force field ranked favorably among the entries submitted to the SAMPL4 host-guest competition [Muddana, et al., J. Comput.-Aided Mol. Des., 2014, 28, 305-317]. In this work we conduct an in-depth analysis of the AMOEBA force field host-guest binding thermodynamics by using both BAR and the orthogonal space random walk (OSRW) methods. The binding entropy-enthalpy contributions are analyzed for each host-guest system. For systems of inordinate binding entropy-enthalpy values, we further examine the hydrogen bonding patterns and configurational entropy contribution. The binding mechanism of this series of host-guest systems varies from ligand to ligand, driven by enthalpy and/or entropy changes. Convergence of BAR and OSRW binding free energy methods is discussed. Ultimately, this work illustrates the value of molecular modelling and advanced force fields for the exploration and interpretation of binding thermodynamics.

The objective of this research was to evaluate the texture and consumer acceptability of goat meat frankfurter formulations with no added fat (NAF), beef fat (BF), or canola oil (CO). Consumer sensory evaluation, fat, and moisture and texture profile analyses were performed on goat meat frankfurters produced with the fat sources BF, CO, and NAF. For sensory evaluations, NAF was less tender (P = 0.007; 4.90 vs. 4.11 and 4.35 for BF and CO, respectively) and the flavor was liked less (P = 0.004; 4.59 vs. 3.83 and 4.30 for BF and CO, respectively); BF was scored as the juiciest (P = 0.003; 3.86 vs. 4.49 and 4.58 for CO and NAF, respectively); and CO had the least amount of flavor (P = 0.029; 3.65 vs. 3.12 and 3.10 for BF and NAF, respectively). Moisture was least (P < 0.001) in CO (46.59%), followed by BF (48.57%) and NAF (55.80%). The amount of fat was not different (P = 0.761) in BF (24.36%) or CO (24.43%) but was less (P < 0.001) in NAF (9.06%), as expected. The NAF had the most protein (P < 0.001; 34.14%), followed by CO (27.98%) and BF (26.07%). For texture profile analyses, NAF had the least hardness value (P = 0.008; 3.92 vs. 4.48 and 4.40 for BF and CO, respectively) and least chewiness value (P = 0.026; 2.89 vs. 3.39 and 3.29 for BF and CO, respectively). Beef fat and CO were not different for hardness (P = 0.596) or chewiness (P = 0.530). No differences were observed in springiness (P = 0.954) or resilience (P = 0.561). The sensory panelists tended to prefer BF for overall acceptability. Results from these data revealed that value-added goat meat products received acceptable sensory scores; therefore, continued research and development will greatly expand the knowledge of goat meat and increase the acceptance of value-added products.

The dual challenge of increasing numbers of older adults and overall increases in those with some form of insurance is driving the need to develop and evaluate novel methods of primary care delivery such as telehealth. The goal of this study was to explore the acceptability and usability of a remote presence robot (RPR) in a simulated primary care wellness encounter for older adults. A descriptive exploratory study was used to determine the acceptability and usability of the RPR operated by an APRN 250 miles from 13 older adults residing in a high rise during a simulated primary care visit. The results support previous research that technology such as the RPR can be both acceptable and useful for an older adult and primary care provider but only in certain circumstances.

1998-01-01

Physicians' acceptance of telemedicine is an important managerial issue facing health-care organizations that have adopted, or are about to adopt, telemedicine. Most previous investigations of the acceptance of telemedicine have lacked theoretical foundation and been of limited scope. We examined technology acceptance and usage among physicians and specialists from 49 clinical departments at eight public tertiary hospitals in Hong Kong. Out of the 1021 questionnaires distributed, 310 were completed and returned, a 30% response rate. The preliminary findings suggested that use of telemedicine among clinicians in Hong Kong was moderate. While 18% of the respondents were using some form of telemedicine for patient care and management, it accounted for only 6.3% of the services provided. The intensity of their technology usage was also low, accounting for only 6.8% of a typical telemedicine-assisted service. These preliminary findings have managerial implications.

Complex band structure and electronic transmission eigenchannels

Jensen, Anders; Strange, Mikkel; Smidstrup, Søren; Stokbro, Kurt; Solomon, Gemma C.; Reuter, Matthew G.

2017-12-01

It is natural to characterize materials in transport junctions by their conductance length dependence, β. Theoretical estimations of β are made employing two primary theories: complex band structure and density functional theory (DFT) Landauer transport. It has previously been shown that the β value derived from total Landauer transmission can be related to the β value from the smallest |ki| complex band; however, it is an open question whether there is a deeper relationship between the two. Here we probe the details of the relationship between transmission and complex band structure, in this case individual eigenchannel transmissions and different complex bands. We present calculations of decay constants for the two most conductive states as determined by complex band structure and standard DFT Landauer transport calculations for one semi-conductor and two molecular junctions. The molecular junctions show that both the length dependence of the total transmission and the individual transmission eigenvalues can be, almost always, found through the complex band structure. The complex band structure of the semi-conducting material, however, does not predict the length dependence of the total transmission but only of the individual channels, at some k-points, due to multiple channels contributing to transmission. We also observe instances of vertical bands, some of which are the smallest |ki| complex bands, that do not contribute to transport. By understanding the deeper relationship between complex bands and individual transmission eigenchannels, we can make a general statement about when the previously accepted wisdom linking transmission and complex band structure will fail, namely, when multiple channels contribute significantly to the transmission.

Thermodynamic properties of tungsten

Grimvall, Göran; Thiessen, Maria; Guillermet, Armando Fernández

1987-11-01

Tungsten has several unusual thermodynamic properties, e.g., very high values of the melting point, the entropy of fusion, the expansion on melting and the lattice anharmonicity. These features are given a semiquantitative explanation, based on the electron density of states N(E). Our treatment includes a numerical calculation of the electronic heat capacity from N(E) and a calculation of the entropy Debye temperature FTHETAS(T) from the vibrational part of the experimental heat capacity. FTHETAS(T) decreases by 36% from 300 K to the melting temperature 3695 K, the largest drop in FTHETAS for elemental metals. Recent quantum-mechanical ab initio calculations of the difference, Hβ/α, in Gibbs energy at T=0 K between the metastable fcc tungsten and the stable bcc phase yield Hβ/α=50+/-5 kJ/mol, which is much larger than the ``experimental'' values Hβ/α=10 and 19 kJ/mol derived from previous semiempirical analyses [the so-called calculation of phase diagrams (``CALPHAD'') method] of binary phase diagrams containing tungsten. We have reanalyzed CALPHAD data, using the results of the first part of this paper. Because of the shapes of N(E) of α-W and β-W, some usually acceptable CALPHAD procedures give misleading results. We give several estimates of Hβ/α, using different assumptions about the hypothetical melting temperature Tβf of fcc W. The more realistic of our estimates gives Hβ/α=30 kJ/mol or larger, thus reducing considerably the previous discrepancy between CALPHAD and ab initio results. The physical picture emerging from this work should be of importance in refinements of the CALPHAD method.

(1) Cash payments should not be accepted from any health-related industry, which might create a conflict of interest, unless it is payment for legitimate research purposes, and the cash is not for purposes of marketing. (2) Marketing gifts, which benefit the patient, are acceptable as long as they are not of substantial value...like equal or less than $100. (3) Conferences (including a "mo dest" meal) sponsored by industry are acceptable when they serve a genuine educational function, and promote objective and scientific activity. (4) Professional people should understand and appreciate the marketing forces, which are endeavoring to influence our behavior. To interact with marketing people is appropriate, not unethical. However we must not be influenced in any way that would disadvantage our patients.

H, C, O stable isotope ratios and the content of some heavy elements of 31 Romanian single-strength organic apple juices collected from four Transylvanian areas are discussed in this study. The aim of this study was to measure the 2H/1H, 18O/16O, 13C/12C ratios of these juices and their elemental profile and to establish a database of authentic values to be used for adulteration and authenticity testing. Our results have shown mean values of δ 18O = −4.2‰ and δDδ−46.5‰, respectively, for apples from Transylvania and at the same time the mean value of δ 13C = −28.2‰. The content of Cd, Pb, U, Zn, As was below the acceptable limits stipulated in US-EPA standard for drinking water. Cu and Cr limits exceeded for one single juice; Ni content for some apple juices from Maramures, Alba, and Cluj was higher than the acceptable value. PMID:22666164

Discrimination of synthesized English vowels by American and Korean listeners

Yang, Byunggon

2004-05-01

This study explored the discrimination of synthesized English vowel pairs by 27 American and Korean, male and female listeners. The average formant values of nine monophthongs produced by ten American English male speakers were employed to synthesize the vowels. Then, subjects were instructed explicitly to respond to AX discrimination tasks in which the standard vowel was followed by another one with the increment or decrement of the original formant values. The highest and lowest formant values of the same vowel quality were collected and compared to examine patterns of vowel discrimination. Results showed that the American and Korean groups discriminated the vowel pairs almost identically and their center formant frequency values of the high and low boundary fell almost exactly on those of the standards. In addition, the acceptable range of the same vowel quality was similar among the language and gender groups. The acceptable thresholds of each vowel formed an oval to maintain perceptual contrast from adjacent vowels. Pedagogical implications of those findings are discussed.

A commercial adzuki bean extract (AE) was evaluated for antioxidant effectiveness in cured and uncured cooked pork sausages. TBARS values, instrumental color evaluation and sensory panel scores were assessed. For uncured sausages, AE at 0.2% was equally effective as 0.1% butylated hydroxytoluene (BHT) in reducing TBARS values. Similarly, AE at 0.2% significantly (P<0.01) reduced the TBARS in cured sausages. Incorporation of 0.2% AE into sausages produced higher (P<0.05) CIE lab color a* value and lower (P<0.05) L* and b* values. Sensory panels did not detect any difference in color, odor, taste, flavor, and overall acceptance in uncured pork sausages with addition of 0.2% AE. However, there were adverse changes in the color and odor of cured sausages, even though the taste, flavor, and overall acceptance were similar. Therefore, the results suggest that AE is a potential antioxidant. Copyright © 2011 Elsevier Ltd. All rights reserved.

To increase legume consumption and give a better protein quality in the snack products, mixtures of fried beans-corn were formulate in different proportions: 60:40 (A); 50:50 (B) and 40:60 (C). Fried corn used in mixtures was previously soaked in a predetermined solution (NaOH/EDTA) and then blanched. Three beans varieties (Pinto 114, Suave 85 and Tórtola Inia) were mixed with fried yellow dent corn in the above described proportions, obtaining nine mixtures whose physical, chemical and sensorial characteristics were evaluated. The mixtures were very homogeneous in all the analyzed characteristics. The protein content for the A mix was the greatest, nevertheless the sensorial analysis showed the last acceptance. The moisture content and water activity of these mixtures was low assuring a good microbiological stability under storage conditions. The protein contribution of each species in different prepared mixtures determined the selection of the best cereal/legume mix. From a nutritional stand point the best results were obtained when the 50% of protein was supplied by bans and the 50% by corn. From the mixtures tried in this study, mix C with bean Pinto 114 one closed to the recommended conditions. Nevertheless, for each cereal/legume mix, the best proportion was C, due to its better acceptability, even though it had less nutritional value.

Mentors require competence at a diverse array of skills to mentor students during clinical practice. According to the latest evidence, competence at mentoring includes: knowledge, skills and attributes of individual students' learning objectives, core elements of nursing, learning processes, a reciprocal and trustful relationship, feedback, evaluation, cooperation with stakeholders, and the mentor's personal qualities. The purpose of the study was to test psychometric properties of a mentor's competence instrument developed to self-evaluate mentors' competence at mentoring nursing students in clinical practice. A cross-sectional, descriptive, explorative study design was used. Data were collected from mentors at five university hospitals in Finland in 2016. A total of 576 mentors participated in this study. The instrument was developed through systematic review, experts' evaluations, and pilot versions of the instrument tested in previous studies. The construct validity and reliability of the instrument were tested using exploratory factor analysis (EFA) with promax rotation and Cronbach's alpha. A 10-factor model showed that the instrument has acceptable construct validity. Cronbach's alpha values for the subscales observed ranged from 0.76 to 0.90. The instrument exhibited acceptable psychometric properties, thereby proving itself a valuable tool for evaluating mentors' competence at mentoring students. Further assessments of its reliability, validity and generality for measuring mentor's competence for mentoring students in different contexts and cultures are recommended.

In 2006, the Housestaff Association presented the Dean at Oregon Health and Science University (OHSU) with a proposal to effectively end the influence of the pharmaceutical industry on campus. The Dean convened a workgroup to examine the issue, and faculty, residents, and medical students were surveyed on their views and interactions. Authors present here the responses from medical students. A web-based, anonymous survey was sent to all OHSU medical students in 2007; 59% completed it. The survey included items measuring attitudes about the pharmaceutical industry and interactions with pharmaceutical representatives (PRs). Only 5% of clinical and 7% of preclinical students agreed that PRs have an important teaching role, and fewer than 1 in 6 believed that PRs provided useful and accurate information on either new or established drugs; 54% of clinical students indicated that PRs should be restricted from making presentations on campus, versus 32% of preclinical students, and only 30% of clinical students agreed that accepting gifts had no impact on their own prescribing, versus 50% of preclinical students. Students who acknowledged the influence of PRs and perceived less educational benefit were less likely to accept gifts such as textbooks; however, 84% of clinical students had attended an on-campus event sponsored by a pharmaceutical company in the previous year. Only a small proportion of OHSU medical students value interactions with PRs, but many still attend events sponsored by pharmaceutical companies.

This study was conducted to analyze the microbiological contamination status of raw beef distributed in Korea, and evaluate the suitability of current aerobic plate count (APC) guidelines. We analyzed five years (2010-2014) of microbiological monitoring data obtained from the Ministry of Food and Drug Safety and investigated the microbiological status of raw beef collected from meat packing centers and meat shops in the Seoul/Gyeonggi, Gangwon, and Chungcheong regions in August 2015. From 2010-2014, most raw beef (>94%) displayed APC levels of < 1.0 × 106 CFU/g. However, raw beef samples collected from all three regions in August 2015 had comparatively higher APC levels than those reported in previous years. To evaluate the relationship between the APC level and quality, changes in beef loin were evaluated during cold storage for 15 days at 4°C. On day 11, the mean APC level (4.7 × 106 CFU/g) conformed to current guidelines in Korea (1.0 × 107 CFU/g) and the pH value was 5.82. However, the sensory evaluation score for color and overall acceptability was under 3.0, meaning that the beef loin was not acceptable for eating. These results suggest that current APC guideline for raw beef should be lowered to 1.0 × 106 CFU/g to improve both the microbiological safety and palatability of raw beef. PMID:29725223

Assessment of the commercial viability of selected options for on-orbit servicing (OOS)

NASA Astrophysics Data System (ADS)

Graham, Andrew Robert; Kingston, Jennifer

2015-12-01

The aim of this paper is to determine the commercial viability of on-orbit servicing of communications satellites in geostationary orbit. Previous studies have shown the technical feasibility of servicing as well as the financial viability of some missions, in particular refuelling, therefore this paper analyses these repair missions and life extension missions. A simple parametric model for simulating communications satellite revenue streams is developed and the results are used to determine the maximum possible revenue for a servicing satellite operator. From this, the maximum cost of the servicing satellite as a proportion of the cost of the communications satellite is determined under three profit scenarios representing zero profit, acceptable profit to an operator in a mature industry and acceptable profit to an operator in an emerging industry. The results show that while servicing is financially viable (zero profit scenario), those missions which result in an increase in Comsat life which is a multiple of the mission duration are more likely to be commercially viable. Refuelling is therefore viable in all cases but life extension in most cases is only marginally viable. Repair missions to satellites which are partially operable are also unlikely to deliver sufficient value to justify carrying out servicing. Also the timing of a servicing mission in relation to the expected remaining life expectancy is a major factor in determining the mission's viability.

Prophylactic human papillomavirus (HPV) vaccines provide promise as a key component of future cervical cancer prevention programs in the Latin America and the Caribbean region. The successful introduction and acceptance of these vaccines will depend on a range of factors including awareness of cervical cancer as a problem, affordability of the vaccine, political will, competition with other vaccines, feasibility of vaccine delivery and acceptability of the vaccine among the range of groups who will influence uptake. While existing data about acceptability from Latin America and the Caribbean is scarce, it is clear that health policymakers, providers and the general public lack knowledge about HPV and cervical cancer. Furthermore, they would value more local epidemiologic data related to cervical cancer. Price is currently a major barrier to vaccine acceptability and a priority for advocacy. More research is required in Latin America and the Caribbean to determine what messages and strategies will work in these communities.

The perceived healthiness of functional foods. A conjoint study of Danish, Finnish and American consumers' perception of functional foods.

PubMed

Bech-Larsen, Tino; Grunert, Klaus G

2003-02-01

Functional foods presumably enable the consumer to lead a healthier life without changing eating habits. Whether consumers accept this proposition or not is potentially influenced by their perceptions of the healthiness of the processing methods, enrichment components, food-types, and health claims used in the production and marketing of functional foods. Because consumers may perceive functional enrichment as interfering with nature, cultural values pertaining to man's manipulation of nature may also influence consumer acceptance of functional foods. The purpose of the study described here is to clarify to which extent Danish, Finnish and American consumers' perceptions of the healthiness of functional foods are explained by the factors mentioned above. The general results indicate that values pertaining to man's manipulation of nature is only modestly related to the acceptance of functional foods, whereas the use of different health claims, processing methods, enrichments, product types, and especially the interactions between the two latter, are important determinants of consumers' perceptions of the healthiness of functional foods.

Much debate exists regarding the need, acceptability, and value of humanitarian medical assistance. We conducted a cross-sectional study on 457 children under 5 years from four remote riverine communities in the Peruvian Amazon and collected anthropometric measures, blood samples (1–4 years), and stool samples. Focus groups and key informant interviews assessed perspectives regarding medical aid delivered by foreigners. The prevalence of stunting, anemia, and intestinal parasites was 20%, 37%, and 62%, respectively. Infection with multiple parasites, usually geohelminths, was detected in 41% of children. The prevalence of intestinal parasites both individual and polyparasitism increased with age. Participants from smaller communities less exposed to foreigners expressed lack of trust and fear of them. However, participants from all communities were positive about foreigners visiting to provide health support. Prevalent health needs such as parasitic infections and anemia may be addressed by short-term medical interventions. There is a perceived openness to and acceptability of medical assistance delivered by foreign personnel. PMID:25846293

The purpose of this study was to retrospectively evaluate the results from a Helical TomoTherapy Hi-Art treatment system relating to quality controls based on daily static and dynamic output checks using statistical process control methods. Individual value X-charts, exponentially weighted moving average charts, and process capability and acceptability indices were used to monitor the treatment system performance. Daily output values measured from January 2014 to January 2015 were considered. The results obtained showed that, although the process was in control, there was an out-of-control situation in the principal maintenance intervention for the treatment system. In particular, process capability indices showed a decreasing percentage of points in control which was, however, acceptable according to AAPM TG148 guidelines. Our findings underline the importance of restricting the acceptable range of daily output checks and suggest a future line of investigation for a detailed process control of daily output checks for the Helical TomoTherapy Hi-Art treatment system.

In laboratory tests, patterns of toxicity were consistent with previous data on pyrethroids. The midge Chaoborus obscuripes was most sensitive (48- and 96-h EC50 = 2.8 ng/L). Other insect larvae (Hemiptera, Ephemeroptera) and macrocrustacea (Amphipoda, Isopoda) were also relatively sensitive, with 48- and 96-h EC50 values between 10 and 100 ng/L. Generally, microcrustacea (Cladocera, Copepoda) and larvae of certain insect groups (Odonata and Chironomidae) were less sensitive, with 48-h EC50 values higher than 100 ng/L. Mollusca and Plathelminthes were insensitive and were unaffected at concentrations at and above the water solubility (5 microg/L). Generally, the EC50 values based on initial population responses in field enclosures were similar to values derived from laboratory tests with the same taxa. Also, the corresponding fifth and tenth percentile hazard concentrations (HC5 and HC10) were similar (laboratory HC5 = 2.7 ng/L and field HC5 = 4.1 ng/L; laboratory and field HC10 = 5.1 ng/L), at least when based on the same sensitive taxonomic groups (insects and crustaceans) and when a similar concentration range was taken into account. In the three field enclosure experiments and at a treatment level of 10 ng/L, consistent effects were observed for only one population (Chaoborus obscuripes), with recovery taking place within 3 to 6 weeks. The laboratory HC5 (2.7 ng/L) and HC10 (5.1 ng/L) based on acute EC50 values of all aquatic arthropod taxa were both lower than this 10 ng/L, a concentration that might represent the "regulatory acceptable concentration." The HC5 and HC10 values in this study in The Netherlands (based on static laboratory tests with freshwater arthropods) were very similar to those derived from a previous study in the United Kingdom (1.4 and 3.3 ng/L). This suggests that for pesticides like lambda-cyhalothrin, HC5 values based on static laboratory tests may provide a conservative estimate of the potential for community-level effects under field conditions. While these HC5 values are conservative for initial effects, they do not provide information on recovery potential, which may be important for regulatory decision-making.

Objective. This study examined the use of psychological acceptance and experiential avoidance, two key concepts of Acceptance and Commitment Therapy (ACT), in the psychological recovery process of people with enduring mental illness. Method. Sixty-seven participants were recruited from the metropolitan, regional, and rural areas of New South Wales, Australia. They all presented some form of chronic mental illness (at least 12 months) as reflected in DSM-IV Axis I diagnostic criteria. The Acceptance and Action Questionnaire (AAQ-19) was used to measure the presence of psychological acceptance and experiential avoidance; the Recovery Assessment Scale (RAS) was used to examine the levels of psychological recovery; and the Scales of Psychological Well-Being was used to observe if there are benefits in utilizing psychological acceptance and experiential avoidance in the recovery process. Results. An analysis of objectively quantifiable measures found no clear correlation between the use of psychological acceptance and recovery in mental illness as measured by the RAS. The data, however, showed a relationship between psychological acceptance and some components of recovery, thereby demonstrating its possible value in the recovery process. Conclusion. The major contribution of this research was the emerging correlation that was observed between psychological acceptance and positive levels of psychological well-being among individuals with mental illness.

This work described study protocols on the production of Palm-Based Standard Reference Materials for iodine value and slip melting point. Thirty-three laboratories collaborated in the inter-laboratory proficiency tests for characterization of iodine value, while thirty-two laboratories for characterization of slip melting point. The iodine value and slip melting point of palm oil, palm olein and palm stearin were determined in accordance to MPOB Test Methods p3.2:2004 and p4.2:2004, respectively. The consensus values and their uncertainties were based on the acceptability of statistical agreement of results obtained from collaborating laboratories. The consensus values and uncertainties for iodine values were 52.63 ± 0.14 Wijs in palm oil, 56.77 ± 0.12 Wijs in palm olein and 33.76 ± 0.18 Wijs in palm stearin. For the slip melting points, the consensus values and uncertainties were 35.6 ± 0.3 °C in palm oil, 22.7 ± 0.4 °C in palm olein and 53.4 ± 0.2 °C in palm stearin. Repeatability and reproducibility relative standard deviations were found to be good and acceptable, with values much lower than that of 10%. Stability of Palm-Based Standard Reference Materials remained stable at temperatures of −20 °C, 0 °C, 6 °C and 24 °C upon storage for one year. PMID:19609396

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.

A possibility for a determination of the fine structure constant in experiments on the bound-electron g-factor is examined. It is found that studying a specific difference of the g-factors of B- and H-like ions of the same spinless isotope in the Pb region to the currently accessible experimental accuracy of 7 x 10(-10) would lead to a determination of the fine structure constant to an accuracy which is better than that of the currently accepted value. Further improvements of the experimental and theoretical accuracy could provide a value of the fine structure constant which is several times more precise than the currently accepted one.

Since the inception of the U.S. Geological Survey National Field Quality Assurance Program, over 85,000 proficiency samples have been analyzed by water-quality analysts. This includes more than 10,000 alkalinity samples, more than 15,000 pH samples, and more than 16,000 specific conductance samples, which were analyzed from 1990 through 1997, and a total of more than 43,000 proficiency samples analyzed from 1979 through 1989. The analyte values were evaluated to determine the fourth-spread, a measure of the width of the middle half of the data, and the F-pseudosigma, a robust replacement for the standard deviation, for each of the different measurement ranges. The result of the statistical evaluation showed that the vast majority of reference sample measurements made by water-quality analysts were within acceptable ranges. From 1990 to 1997, the measurement of pH had the highest level of acceptable results, 98.4 percent, followed by specific conductance with 95.2 percent acceptable results, and alkalinity with 88.6 percent acceptable results. The statistical summary of pH indicates the calculated fourth-spread values for the entire tested range is +0.06 pH units. For specific conductance, the magnitude of the fourth-spread increases as the magnitude of the specific conductance ranges increases. The average relative fourth-spread percent for all reported specific conductance values is +1.8 percent. From 1990 through 1997, the evaluation of the results for alkalinity measurement for the average fourth-spread was determined to be + 3.3 milligrams per liter as calcium carbonate.

Single-Photon Emission of a Hydrogenlike Atom

NASA Astrophysics Data System (ADS)

Skobelev, V. V.

2016-11-01

Implementing a previously obtained, original solution of the Dirac equation for an electron in the field of a nucleus ( Ze) expressed in terms of the wave function of the corresponding Schrödinger equation and its derivatives in spherical coordinates and the spin projection operator Σ3 associated with the eigenfunction, taking into account in each component of the spinor the leading term of the expansion in the small parameter ( Zα), α = e 2 / ħc ≈ 1 / 137, the partial probabilities W of emission of a photon ( Zα)* → ( Zα) + γ have been calculated. Here two orthogonal states of the linear polarization of the photon, and also the spin states of the electron, which previously had not been taken into consideration, have been taken into account in the transverse gauge. It turns out that the probabilities W of emission of a photon per unit time for any allowed transitions are proportional to (Zα)4, as was previously accepted, and the selection rules for the quantum number m have the usual form Δ m = 0,±1. It was found that a spin flip does not take place during emission. In contrast to the customary situation with the selection rules for the quantum number l being of the form Δ l = ±1, for Δ m = ±1 there also exist integrals over dcosθ which are not equal to zero for undetermined odd values of Δ l. In this, and also in a fundamentally different dependence of the amplitude on the quantum numbers consist the differences from the traditional approach to the problem. Necessary conditions are formulated, under the fulfillment of which the selection rules for l are not changed, having values Δ l = ±1 for arbitrary Δ m, but it was not possible, however, to give a complete proof of these rules.

Dengue viruses have spread widely in recent decades and cause tens of millions of infections mostly in tropical and subtropical areas. Vaccine candidates are being studied aggressively and may be ready for licensure soon. We surveyed patients with past or upcoming travel to dengue-endemic countries to assess rates and determinants of acceptance for four hypothetical dengue vaccines with variable efficacy and adverse event (AE) profiles. Acceptance ratios were calculated for vaccines with varied efficacy and AE risk. Acceptance of the four hypothetical vaccines ranged from 54% for the vaccine with lower efficacy and serious AE risk to 95% for the vaccine with higher efficacy and minor AE risk. Given equal efficacy, vaccines with lower AE risk were better accepted than those with higher AE risk; given equivalent AE risk, vaccines with higher efficacy were better accepted than those with lower efficacy. History of Japanese encephalitis vaccination was associated with lower vaccine acceptance for one of the hypothetical vaccines. US-born travelers were more likely than non-US born travelers to accept a vaccine with 75% efficacy and a risk of minor AEs (p = 0.003). Compared with North American-born travelers, Asian- and African-born travelers were less likely to accept both vaccines with 75% efficacy. Most travelers would accept a safe and efficacious dengue vaccine if one were available. Travelers valued fewer potential AEs over increased vaccine efficacy. © 2013 International Society of Travel Medicine.

"Let's get the best quality research we can": public awareness and acceptance of consent to use existing data in health research: a systematic review and qualitative study.

PubMed

Hill, Elizabeth M; Turner, Emma L; Martin, Richard M; Donovan, Jenny L

2013-06-04

Opt-in consent is usually required for research, but is known to introduce selection bias. This is a particular problem for large scale epidemiological studies using only pre-collected health data. Most previous studies have shown that members of the public value opt-in consent and can perceive research without consent as an invasion of privacy. Past research has suggested that people are generally unaware of research processes and existing safeguards, and that education may increase the acceptability of research without prior informed consent, but this recommendation has not been formally evaluated. Our objectives were to determine the range of public opinion about the use of existing medical data for research and to explore views about consent to a secondary review of medical records for research. We also investigated the effect of the provision of detailed information about the potential effect of selection bias on public acceptability of the use of data for research. We carried out a systematic review of existing literature on public attitudes to secondary use of existing health records identified by searching PubMed (1966-present), Embase (1974-present) and reference lists of identified studies to provide a general overview, followed by a qualitative focus group study with 19 older men recruited from rural and suburban primary care practices in the UK to explore key issues in detail. The systematic review identified twenty-seven relevant papers and the findings suggested that males and older people were more likely to consent to a review of their medical data. Many studies noted participants' lack of knowledge about research processes and existing safeguards and this was reflected in the focus groups. Focus group participants became more accepting of the use of pre-collected medical data without consent after being given information about selection bias and research processes. All participants were keen to contribute to NHS-related research but some were concerned about data-sharing for commercial gain and the potential misuse of information. Increasing public education about research and specific targeted information provision could promote trust in research processes and safeguards, which in turn could increase the acceptability of research without specific consent where the need for consent would lead to biased findings and impede research necessary to improve public health.

Visualization of seismic tomography on Google Earth: Improvement of KML generator and its web application to accept the data file in European standard format

NASA Astrophysics Data System (ADS)

Yamagishi, Y.; Yanaka, H.; Tsuboi, S.

2009-12-01

We have developed a conversion tool for the data of seismic tomography into KML, called KML generator, and made it available on the web site (http://www.jamstec.go.jp/pacific21/google_earth). The KML generator enables us to display vertical and horizontal cross sections of the model on Google Earth in three-dimensional manner, which would be useful to understand the Earth's interior. The previous generator accepts text files of grid-point data having longitude, latitude, and seismic velocity anomaly. Each data file contains the data for each depth. Metadata, such as bibliographic reference, grid-point interval, depth, are described in other information file. We did not allow users to upload their own tomographic model to the web application, because there is not standard format to represent tomographic model. Recently European seismology research project, NEIRES (Network of Research Infrastructures for European Seismology), advocates that the data of seismic tomography should be standardized. They propose a new format based on JSON (JavaScript Object Notation), which is one of the data-interchange formats, as a standard one for the tomography. This format consists of two parts, which are metadata and grid-point data values. The JSON format seems to be powerful to handle and to analyze the tomographic model, because the structure of the format is fully defined by JavaScript objects, thus the elements are directly accessible by a script. In addition, there exist JSON libraries for several programming languages. The International Federation of Digital Seismograph Network (FDSN) adapted this format as a FDSN standard format for seismic tomographic model. There might be a possibility that this format would not only be accepted by European seismologists but also be accepted as the world standard. Therefore we improve our KML generator for seismic tomography to accept the data file having also JSON format. We also improve the web application of the generator so that the JSON formatted data file can be uploaded. Users can convert any tomographic model data to KML. The KML obtained through the new generator should provide an arena to compare various tomographic models and other geophysical observations on Google Earth, which may act as a common platform for geoscience browser.

Development of quantitative risk acceptance criteria

Griesmeyer, J. M.; Okrent, D.

Some of the major considerations for effective management of risk are discussed, with particular emphasis on risks due to nuclear power plant operations. Although there are impacts associated with the rest of the fuel cycle, they are not addressed here. Several previously published proposals for quantitative risk criteria are reviewed. They range from a simple acceptance criterion on individual risk of death to a quantitative risk management framework. The final section discussed some of the problems in the establishment of a framework for the quantitative management of risk.

Beliefs and social behavior in a multi-period ultimatum game

PubMed Central

Azar, Ofer H.; Lahav, Yaron; Voslinsky, Alisa

2015-01-01

We conduct a multi-period ultimatum game in which we elicit players' beliefs. Responders do not predict accurately the amount that will be offered to them, and do not get better in their predictions over time. At the individual level we see some effect of the mistake in expectations in the previous period on the responder's expectation about the offer in the current period, but this effect is relatively small. The proposers' beliefs about the minimum amount that responders will accept is significantly higher than the minimum amount responders believe will be accepted by other responders. The proposer's belief about the minimal acceptable offer does not change following a rejection. Nevertheless, the proposer's offer in the next period does increase following a rejection. The probability of rejection increases when the responder has higher expectations about the amount that will be offered to him or higher beliefs about the minimal amount that other responders will accept.

Are photographic records reliable for orthodontic screening?

PubMed

Mandall, N A

2002-06-01

The aim of the study was to evaluate the reliability of a panel of orthodontists for accepting new patient referrals based on clinical photographs. Eight orthodontists from Greater Manchester, Lancashire, Chester, and Derbyshire observed clinical photographs of 40 consecutive new patients attending the orthodontic department, Hope Hospital, Salford. They recorded whether or not they would accept the patient, as a new patient referral, in their department. Each consultant was asked to take into account factors, such as oral hygiene, dental development, and severity of the malocclusion. Kappa statistic for multiple-rater agreement and kappa statistic for intra-observer reliability were calculated. Inter-observer panel agreement for accepting new patient referrals based on photographic information was low (multiple rater kappa score 0.37). Intra-examiner agreement was better (kappa range 0.34-0.90). Clinician agreement for screening and accepting orthodontic referrals based on clinical photographs is comparable to that previously reported for other clinical decision making.

An acceptance model for smart glasses based tourism augmented reality

Obeidy, Waqas Khalid; Arshad, Haslina; Huang, Jiung Yao

2017-10-01

Recent mobile technologies have revolutionized the way people experience their environment. Although, there is only limited research on users' acceptance of AR in the cultural tourism context, previous researchers have explored the opportunities of using augmented reality (AR) in order to enhance user experience. Recent AR research lack works that integrates dimensions which are specific to cultural tourism and smart glass specific context. Hence, this work proposes an AR acceptance model in the context of cultural heritage tourism and smart glasses capable of performing augmented reality. Therefore, in this paper we aim to present an AR acceptance model to understand the AR usage behavior and visiting intention for tourists who use Smart Glass based AR at UNESCO cultural heritage destinations in Malaysia. Furthermore, this paper identifies information quality, technology readiness, visual appeal, and facilitating conditions as external variables and key factors influencing visitors' beliefs, attitudes and usage intention.

Labeling Sexual Victimization Experiences: The Role of Sexism, Rape Myth Acceptance, and Tolerance for Sexual Harassment.

PubMed

LeMaire, Kelly L; Oswald, Debra L; Russell, Brenda L

2016-01-01

This study investigated whether attitudinal variables, such as benevolent and hostile sexism toward men and women, female rape myth acceptance, and tolerance of sexual harassment are related to women labeling their sexual assault experiences as rape. In a sample of 276 female college students, 71 (25.7%) reported at least one experience that met the operational definition of rape, although only 46.5% of those women labeled the experience "rape." Benevolent sexism, tolerance of sexual harassment, and rape myth acceptance, but not hostile sexism, significantly predicted labeling of previous sexual assault experiences by the victims. Specifically, those with more benevolent sexist attitudes toward both men and women, greater rape myth acceptance, and more tolerant attitudes of sexual harassment were less likely to label their past sexual assault experience as rape. The results are discussed for their clinical and theoretical implications.

Physicochemical and Sensory Characteristics of Sponge Cakes with Rubus coreanus Powder

Lee, Jun Ho

2015-01-01

To develop new type of sponge cake, the effects of partial (0~40%) replacement with Rubus coreanus powder (RCP) on the quality characteristics of sponge cakes were investigated. The pH level and moisture content ranged from 4.05~8.23 and 28.49~36.59, respectively, and significantly decreased upon addition of RCP (P<0.05). Baking loss rate and cake firmness significantly increased with higher RCP content in the formulation, whereas morphological characteristics of cakes such as height, volume, and symmetry indices significantly decreased (P<0.05). For crumb color values, L*- and b*-values significantly decreased while a*-value significantly increased as a result of RCP substitution (P<0.05). Hedonic sensory results indicated that sponge cakes supplemented with 30~40% RCP showed the most favorable acceptance scores for most of the sensory attributes evaluated. Overall, Rubus coreanus sponge cake could be developed with comparable physicochemical qualities without sacrificing consumer acceptability. PMID:26451358

Military handbook: Metallic materials and elements for aerospace vehicle structures, volume 1

NASA Astrophysics Data System (ADS)

1994-11-01

Since many aerospace companies manufacture both commercial and military products, the standardization of metallic materials design data, which are acceptable to government procuring or certification agencies, is very beneficial to those manufacturers as well as governmental agencies. Although the design requirements for military and commercial products may differ greatly, the required design values for the strength of materials and elements and other needed material characteristics are often identical. Therefore this publication is to provide standardized design values and related design information for metallic materials and structural elements used in aerospace structures. The data contained herein or from approved items in the minutes of MIL-RDBK-5 coordination meetings are acceptable to the Air Force, the Navy, the Army, and the Federal Aviation Administration. Approval by the procuring or certificating agency must be obtained for the use of design values for products not contained herein.

Mental Health: The Search for a Definition

PubMed Central

Tucker, D. K.; le Riche, W. Harding

1964-01-01

Various attempts to define the concept of “mental health” are examined. Value judgments permeate much mental health literature. Their use militates against obtaining an objective definition, capable of universal application. The acceptance of a definition including a value judgment implies taking an attitude toward a particular society and its social ideals. Present limits of competence only allow us to describe “mental health” conceptually. Such “untechnical” proposals are liable to be confused with “technical” (“scientific”) propositions. Multiple criteria are likely to be helpful in improving our concept of “mental health”. The intrusion of morals into the world of health is discussed as part of the contemporary intellectual dilemma of determined human behaviour versus human responsibility and the reality of moral values. It is suggested that “mental health” might consist simply of an individual's possession of insight into his own personality, combined with an honest recognition and acceptance of his condition.

2008-07-01

A problem commonly encountered in programs for prevention of mother-to-child-transmission (PMTCT) of HIV in sub-Saharan Africa is low rates of HIV test acceptance among pregnant women. In this study, we examined risk factors and reasons for HIV test refusal among 432 women attending three antenatal care clinics offering PMTCT in urban and semi-urban parts of the Mbarara district, Uganda. Structured interviews were performed following pre-test counselling. Three-hundred-eighty women were included in the study, 323 (85%) of whom accepted HIV testing. In multivariate analysis, testing site (Site A: OR = 1.0; Site B: OR = 3.08; 95%CI: 1.12-8.46; Site C: OR = 5.93; 95%CI: 2.94-11.98), age between 30 and 34 years (<20 years: OR = 1.0; 20-24 years: OR = 1.81; 95%CI: 0.58-5.67; 25-29 years: OR = 2.15; 95%CI: 0.66-6.97; 30-34 years: OR = 3.88; 95%CI: 1.21-13.41), mistrust in reliability of the HIV test (OR = 20.60; 95%CI: 3.24-131.0) and not having been tested for HIV previously (OR = 2.15; 95%CI: 1.02-4.54) were associated with test refusal. Testing sites operating for longer durations had higher rates of acceptance. The most common reasons claimed for test refusal were: lack of access to antiretroviral therapy (ART) for HIV-infected women (88%; n=57), a need to discuss with partner before decision (82%; n=57) and fear of partner's reaction (54%; n=57). Comparison with previous periods showed that the acceptance rate increased with the duration of the program. Our study identified risk factors for HIV test refusal among pregnant women in Uganda and common reasons for not accepting testing. These findings may suggest modifications and improvements in the performance of HIV testing in this and similar populations.

Mindfulness-based stress reduction and cognitive behavioral therapy for chronic low back pain: similar effects on mindfulness, catastrophizing, self-efficacy, and acceptance in a randomized controlled trial.

Cognitive behavioral therapy (CBT) is believed to improve chronic pain problems by decreasing patient catastrophizing and increasing patient self-efficacy for managing pain. Mindfulness-based stress reduction (MBSR) is believed to benefit patients with chronic pain by increasing mindfulness and pain acceptance. However, little is known about how these therapeutic mechanism variables relate to each other or whether they are differentially impacted by MBSR vs CBT. In a randomized controlled trial comparing MBSR, CBT, and usual care (UC) for adults aged 20 to 70 years with chronic low back pain (N = 342), we examined (1) baseline relationships among measures of catastrophizing, self-efficacy, acceptance, and mindfulness and (2) changes on these measures in the 3 treatment groups. At baseline, catastrophizing was associated negatively with self-efficacy, acceptance, and 3 aspects of mindfulness (nonreactivity, nonjudging, and acting with awareness; all P values <0.01). Acceptance was associated positively with self-efficacy (P < 0.01) and mindfulness (P values <0.05) measures. Catastrophizing decreased slightly more posttreatment with MBSR than with CBT or UC (omnibus P = 0.002). Both treatments were effective compared with UC in decreasing catastrophizing at 52 weeks (omnibus P = 0.001). In both the entire randomized sample and the subsample of participants who attended ≥6 of the 8 MBSR or CBT sessions, differences between MBSR and CBT at up to 52 weeks were few, small in size, and of questionable clinical meaningfulness. The results indicate overlap across measures of catastrophizing, self-efficacy, acceptance, and mindfulness and similar effects of MBSR and CBT on these measures among individuals with chronic low back pain.

Both treatments were effective compared with UC in decreasing catastrophizing at 52 weeks (omnibus P = 0.001). In both the entire randomized sample and the sub-sample of participants who attended ≥6 of the 8 MBSR or CBT sessions, differences between MBSR and CBT at up to 52 weeks were few, small in size, and of questionable clinical meaningfulness. The results indicate overlap across measures of catastrophizing, self-efficacy, acceptance, and mindfulness, and similar effects of MBSR and CBT on these measures among individuals with CLBP.

To evaluate the occurrence of out-of acceptable ranges and accuracy of antimicrobial susceptibility tests, we applied a new statistical tool to the Inter-Laboratory Quality Control Program established by the Kyushu Quality Control Research Group. First, we defined acceptable ranges of minimum inhibitory concentration (MIC) for broth microdilution tests and inhibitory zone diameter for disk diffusion tests on the basis of Clinical and Laboratory Standards Institute (CLSI) M100-S21. In the analysis, more than two out-of acceptable range results in the 20 tests were considered as not allowable according to the CLSI document. Of the 90 participating laboratories, 46 (51%) experienced one or more occurrences of out-of acceptable range results. Then, a binomial test was applied to each participating laboratory. The results indicated that the occurrences of out-of acceptable range results in the 11 laboratories were significantly higher when compared to the CLSI recommendation (allowable rate < or = 0.05). The standard deviation indices(SDI) were calculated by using reported results, mean and standard deviation values for the respective antimicrobial agents tested. In the evaluation of accuracy, mean value from each laboratory was statistically compared with zero using a Student's t-test. The results revealed that 5 of the 11 above laboratories reported erroneous test results that systematically drifted to the side of resistance. In conclusion, our statistical approach has enabled us to detect significantly higher occurrences and source of interpretive errors in antimicrobial susceptibility tests; therefore, this approach can provide us with additional information that can improve the accuracy of the test results in clinical microbiology laboratories.

Men who have sex with men (MSM) may benefit from human papillomavirus (HPV) vaccine due to increased risk for HPV infection and related disease. We assessed HPV vaccine acceptability and sexual experience prior to disclosure to Health Care Providers (HCP) to understand implications of targeted vaccination strategies for MSM. From July 2008 to February 2009, 1169 MSM aged ≥19 years were recruited at community venues in Vancouver. We assessed key variables from a self-administered questionnaire and independent predictors of HPV vaccine acceptability using multivariate logistic regression. Of 1041 respondents, 697 (67.0%) were willing to receive HPV vaccine and 71.3% had heard of HPV. Significant multivariate predictors of higher vaccine acceptability were (adjusted odds ratio [95% CI]): previous diagnosis of genital warts (1.7 [1.1, 2.6]), disclosure of sexual behavior to HCP (1.6 [1.1, 2.3]), annual income at least $20,000 (1.5 [1.1, 2.1]), previous hepatitis A or B vaccination (1.4 [1.0, 2.0]), and no recent recreational drug use (1.4 [1.0, 2.0]). Most MSM (78.7%) had disclosed sexual behavior to HCP and median time from first sexual contact with males to disclosure was 6.0 years (IQR 2-14 years); for men ≤26 years these were 72.0% and 3.0 years (IQR 1-8 years) respectively. Willingness to receive HPV vaccine was substantial among MSM in Vancouver; however, acceptability varied by demographics, risk, and health history. HPV vaccine programs delivered by HCP would offer limited benefit given the duration of time from sexual debut to disclosure to HCP. Crown Copyright © 2012. Published by Elsevier Ltd.

Pain relief is nearly regarded as the right of patients in modern day health care. Women undergo excruciating pain during normal vaginal delivery (NVD). However, the acceptance of labor analgesia (LA) has remained very poor. The present study was aimed to assess the correlation of previous exposure to such pain (parity) and school education with LA acceptance. The present comparative study was conducted with a total 400 consented participants. A questionnaire was used to collect sociodemographic variables, acceptance/nonacceptance of LA, and the reasons for not opting for LA in upcoming delivery were noted. Participants were divided into primiparous, multiparous, and nulliparous (control). They were also grouped as per school education and compared taking illiterates as controls. Data are presented in absolute number. Fisher's exact test is used for comparison; P < 0.05 was considered statistically significant. Seventy (17.5%) multiparous and 38% primiparous participants were compared with 44.5% nulliparous women. Only 2.75% participants were illiterate. 69.50% were rural inhabitant and 81.50% believed in Hinduism. 87.14% multiparous, 84.21% primiparous, and 88.76% nulliparous women declined LA ( P > 0.05). The desire to experience NVD without LA as a reason for nonacceptance was significantly less among primiparous and multiparous as compared to nulliparous ( P < 0.0001), but not among literate and illiterate participants ( P > 0.295 in all). Previous labor pain significantly reduces the desire to experience NVD without LA, but still more than 80% parturients of any parity do not want LA due to one or more reasons. School education has no impact on LA acceptance.

This paper describes the Controller Acceptability Study 1 (CAS-1) experiment that was conducted by NASA Langley Research Center personnel from January through March 2014 and presents partial CAS-1 results. CAS-1 employed 14 air traffic controller volunteers as research subjects to assess the viability of simulated future unmanned aircraft systems (UAS) operating alongside manned aircraft in moderate-density, moderate-complexity Class E airspace. These simulated UAS were equipped with a prototype pilot-in-the-loop (PITL) Detect and Avoid (DAA) system, specifically the Self-Separation (SS) function of such a system based on Stratway+ software to replace the see-and-avoid capabilities of manned aircraft pilots. A quantitative CAS-1 objective was to determine horizontal miss distance (HMD) values for SS encounters that were most acceptable to air traffic controllers, specifically HMD values that were assessed as neither unsafely small nor disruptively large. HMD values between 0.5 and 3.0 nautical miles (nmi) were assessed for a wide array of encounter geometries between UAS and manned aircraft. The paper includes brief introductory material about DAA systems and their SS functions, followed by descriptions of the CAS-1 simulation environment, prototype PITL SS capability, and experiment design, and concludes with presentation and discussion of partial CAS-1 data and results.

Longitudinal records of blood pressure (BP) and heart rate (HR) around the clock for days, weeks, months, years, and even decades obtained by manual self-measurements (during waking) and/or automatically by ambulatory monitoring reveal, in addition to well-known large within-day variation, also considerable day-to-day variability in most people, whether normotensive or hypertensive. As a first step, the circadian rhythm is considered along with gender differences and changes as a function of age to derive time-specified reference values (chronodesms), while reference values accumulate to also account for the circaseptan variation. Chronodesms serve for the interpretation of single measurements and of circadian and other rhythm parameters. Refined diagnoses can thus be obtained, namely MESOR-hypertension when the chronome-adjusted mean value (MESOR) of BP is above the upper limit of acceptability, excessive pulse pressure (EPP) when the difference in MESOR between the systolic (S) and diastolic (D) BP is too large, CHAT (circadian hyper-amplitude tension) when the circadian BP amplitude is excessive, DHRV (decreased heart rate variability) when the standard deviation (SD) of HR is below the acceptable range, and/or ecphasia when the overall high values recurring each day occur at an odd time (a condition also contributing to the risk associated with 'non-dipping'). A non-parametric approach consisting of a computer comparison of the subject's profile with the time-varying limits of acceptability further serves as a guide to optimize the efficacy of any needed treatment by timing its administration (chronotherapy) and selecting a treatment schedule best suited to normalize abnormal patterns in BP and/or HR. The merit of the proposed chronobiological approach to BP screening, diagnosis and therapy (chronotheranostics) is assessed in the light of outcome studies. Elevated risk associated with abnormal patterns of BP and/or HR variability, even when most if not all measurements lie within the range of acceptable values, becomes amenable to treatment as a critical step toward prevention (prehabilitation) to reduce the need for rehabilitation (the latter often after costly surgical intervention).

Although vaccination against the Human Papilloma Virus (HPV) reduces the risk of related morbidities, the vaccine uptake remains low in adolescents. This has been attributed to limited parental knowledge and misconceptions. In this cross sectional study, we assessed the (1) clarity of educational material informing Hispanic mothers about HPV, cervical cancer and the HPV vaccine, (2) determined vaccination acceptability and (3) identified predictors of vaccine acceptance in an underserved health setting. 418 Hispanic mothers received the educational material and completed an anonymous survey. 91 % of participants understood most or all of the information provided. 77 % of participants reported vaccine acceptance for their children; this increased to 84 % when only those with children eligible to receive vaccination were included. Significant positive predictors of maternal acceptance of the HPV vaccine for their children were understanding most or all of the provided information, older age and acceptance of the HPV vaccine for themselves. Concerns about safety and general dislike of vaccines were negatively associated with HPV vaccine acceptance. Prior knowledge, level of education, previous relevant gynecologic history, general willingness to vaccinate and other general beliefs about vaccines were not significantly associated with HPV vaccine acceptance. The majority of participants reported understanding of the provided educational material. Vaccine acceptability was fairly high, but was even higher among those who understood the information. This study documents a cost-effective way to provide Hispanic mothers with easy-to-understand HPV-related information that could increase parental vaccine acceptability and future vaccine uptake among their children.

The body mass index (BMI) is widely accepted as a measure of overweight and obesity in children. There are no BMI reference charts for Algerian children and adolescents. The purpose of this study was to construct BMI percentile curves appropriate for children aged 6-18 years in Algeria. The weight and height of 7772 (54.9% girls) healthy schoolchildren from Constantine (eastern Algeria) were measured in 2008/2009. Weight and height for age curves based on the same sample were published previously. The BMI for age percentile curves were estimated in girls and boys separately using the LMS smoothing method. In both sexes, the median BMI increased with age. Girls had lower BMI values than boys before the age of 10 years but they were higher after this age until 18 years of age. Within the study population, the prevalence of overweight (including obesity) and obesity in girls and boys together was 13.7% and 3.0%, respectively, according to the International Obesity Task Force (IOTF) and 16.9% and 4.9% according to the World Health Organization (WHO) (2007). The median BMI curves of Algerian girls and boys were generally lower than those observed in other Arab countries. Compared with other references, the median BMI values of girls were lower than those of a Belgian Flemish population and WHO 2007 until 14 years of age and higher than the French reference between 7 and 18 years of age. The BMI values of Algerian boys were close to the Belgian (Flemish population), French and WHO 2007 references between 6 and 9 years of age and generally lower thereafter. These BMI curves are complementary to the height and weight charts published previously for the assessment of growth in children and adolescents. They were developed according to international guidelines and could serve as a national reference. They could be used as a complement to the 0- to 5-year-old WHO 2006 standards.

Expert views on societal responses to different applications of nanotechnology: a comparative analysis of experts in countries with different economic and regulatory environments

NASA Astrophysics Data System (ADS)

Gupta, Nidhi; Fischer, Arnout R. H.; George, Saji; Frewer, Lynn J.

2013-08-01

The introduction of different applications of nanotechnology will be informed by expert views regarding which (types of) application will be most societally acceptable. Previous research in Northern Europe has indicated that experts believe that various factors will be influential, predominant among these being public perceptions of benefit, need and consumer concern about contact with nanomaterials. These factors are thought by experts to differentiate societal acceptance and rejection of nanotechnology applications. This research utilises a larger sample of experts ( N = 67) drawn from Northern America, Europe, Australasia, India and Singapore to examine differences in expert opinion regarding societal acceptance of different applications of nanotechnology within different technological environments, consumer cultures and regulatory regimes. Perceived risk and consumer concerns regarding contact with nano-particles are thought by all experts to drive rejection, and perceived benefits to influence acceptance, independent of country. Encapsulation and delivery of nutrients in food was thought to be the most likely to raise societal concerns, while targeted drug delivery was thought most likely to be accepted. Lack of differentiation between countries suggests that expert views regarding social acceptance may be homogenous, independent of local contextual factors.

Exposure Range For Cine Radiographic Procedures

NASA Astrophysics Data System (ADS)

Moore, Robert J.

1980-08-01

Based on the author's experience, state-of-the-art cine radiographic equipment of the type used in modern cardiovascular laboratories for selective coronary arteriography must perform at well-defined levels to produce cine images with acceptable quantum mottle, contrast, and detail, as judged by consensus of across section of American cardiologists/radiologists experienced in viewing such images. Accordingly, a "standard" undertable state-of-the-art cine radiographic imaging system is postulated to answer the question of what patient exposure range is necessary to obtain cine images of acceptable quality. It is shown that such a standard system would be expected to produce a 'tabletop exposure of about 25 milliRoentgens per frame for the "standard" adult patient, plus-or-minus 33% for accept-able variation of system parameters. This means that for cine radiography at 60 frames per second (30 frames per second) the exposure rate range based on this model is 60 to 120 Roentgens per minute (30 to 60 Roentgens per minute). The author contends that studies at exposure levels below these will yield cine images of questionable diagnostic value; studies at exposure levels above these may yield cine images of excellent visual quality but having little additional diagnostic value, at the expense of added patient/personnel radiation exposure and added x-ray tube heat loading.

Natural and Anthropogenic Factors Controlling the Down Profile Increase in δ13C of Soil Organic Matter

NASA Astrophysics Data System (ADS)

Serach, L.; Breecker, D.

2016-12-01

The increases in the stable C isotope ratio (δ13C) of soil organic carbon (SOC) with depth common in well-drained soils are widely accepted as being due to the C isotope fractionation between CO2 and SOC during microbial respiration. However, results from previous studies that investigate C isotope fractionation during respiration are conflicting. Respired CO2 with 13C values lower, higher and not significantly different than the associated SOC have been reported in the literature. This project aims to quantify the contribution of isotopic fractionation during microbial respiration to the down-profile shift in δ13C values by means of a long-term (2 year) incubation of topsoil (0-2cm). The topsoil used in the incubations was collected from undisturbed temperate and tropical forests. At each location, soil profiles from 0-20 cm depth were also collected and the down profile trends in concentrations and δ13C values of bulk organic carbon were measured. The CO2-SOC carbon isotope enrichment factor ɛCO2-SOM required to explain each profile was then calculated. We compared these calculated ɛCO2-SOM values with empirical values determined from soil incubations. ɛCO2-SOM values were determined from incubations as the difference between δ13C values of headspace CO2 and bulk SOC. We have thus far measured these δ13C values at 1,4 and 7 months, allowing us to track if and when empirical ɛCO2-SOM values reach the magnitude required to explain the profiles. Thus far, all empirical ɛCO2-SOM values are either too small or of the wrong sign to explain the profiles, suggesting that a mechanism other than C isotope fractionation during microbial respiration may be responsible. Therefore, we are also investigating the possibility that the anthropogenic increase in concentrations of atmospheric CO2, through its influence on δ13C values of C3 plants, explains a substantial portion of the typical down profile increase in SOC δ13C values.

Estimation of the Mean Axon Diameter and Intra-axonal Space Volume Fraction of the Human Corpus Callosum: Diffusion q-space Imaging with Low q-values.

2016-01-01

Q-space imaging (QSI) is a diffusion-weighted imaging (DWI) technique that enables investigation of tissue microstructure. However, for sufficient displacement resolution to measure the microstructure, QSI requires high q-values that are usually difficult to achieve with a clinical scanner. The recently introduced "low q-value method" fits the echo attenuation to only low q-values to extract the root mean square displacement. We investigated the clinical feasibility of the low q-value method for estimating the microstructure of the human corpus callosum using a 3.0-tesla clinical scanner within a clinically feasible scan time. We performed a simulation to explore the acceptable range of maximum q-values for the low q-value method. We simulated echo attenuations caused by restricted diffusion in the intra-axonal space (IAS) and hindered diffusion in the extra-axonal space (EAS) assuming 100,000 cylinders with various diameters, and we estimated mean axon diameter, IAS volume fraction, and EAS diffusivity by fitting echo attenuations with different maximum q-values. Furthermore, we scanned the corpus callosum of 7 healthy volunteers and estimated the mean axon diameter and IAS volume fraction. Good agreement between estimated and defined values in the simulation study with maximum q-values of 700 and 800 cm(-1) suggested that the maximum q-value used in the in vivo experiment, 737 cm(-1), was reasonable. In the in vivo experiment, the mean axon diameter was larger in the body of the corpus callosum and smaller in the genu and splenium, and this anterior-to-posterior trend is consistent with previously reported histology, although our mean axon diameter seems larger in size. On the other hand, we found an opposite anterior-to-posterior trend, with high IAS volume fraction in the genu and splenium and a lower fraction in the body, which is similar to the fiber density reported in the histology study. The low q-value method may provide insights into tissue microstructure using a 3T clinical scanner within clinically feasible scan time.

Skepticism and Denial: Drawing a line

NASA Astrophysics Data System (ADS)

Byrne, J. M.; Brown, M. B.; Peacock, K.

2016-12-01

Climate denialism is distinct from a merely skeptical attitude towards generally accepted views in climate science. But drawing the line between them takes care—there are similarities between skepticism and denial, including a shared reluctance to accept conclusions that nearly all qualified scientists take to be well-justified. Here we will explore both how to draw the line, and how to effectively communicate the differences between denial and skepticism. Identifying which of these two terms best describes someone's attitude turns on whether they reject a generally accepted view based on a `high threshold' for acceptance of conclusions in general, or from a preference that the conclusion in question be false. In most cases, denialism manifests in disregard and mistreatment of evidence, including selective quotation, credulous endorsement of bad sources and incredulous rejection of good sources. Historically, current accepted views became dominant as alternatives were excluded and arguments supporting current views accumulated. The accumulated record of evidence and successful application of those views sets a high bar for proposed alternatives to them. Pure skeptics may refuse to endorse generally accepted views without rejecting or distorting the strong evidence for those views, and typically support policy responses based on the implications of that evidence. But deniers who reject scientific conclusions reject the evidence for those views while endorsing views that a true skeptic would regard as less plausible and well-supported than the accepted views. Thus motivated cognition is the key to defining denial. Pascal's famous argument for belief in God illustrates the problem: even assuming God's existence to be extremely improbable, the expected value of believing is far higher than the expected value of disbelieving. But Pascal's argument undermines its own methodology: without reasons to rely on beliefs as reliable guides to successful action, cost-benefit calculations cannot be justified at all. The contribution of this work to the proposed course will aim to ensure students learn how the basic principles needed to understand anthropogenic warming emerged, and why those principles are solidly grounded.

Improvements in Depression and Mental Health After Acceptance and Commitment Therapy are Related to Changes in Defusion and Values-Based Action.

PubMed

Bramwell, Kate; Richardson, Thomas

2018-01-01

Acceptance and commitment therapy (ACT) has been found to be effective for various mental health disorders but the processes through which it affects change remain unclear. Much process research in the area is on physical rather than mental health, and focuses on the broad concept of psychological flexibility with little research on specific mechanisms identified in theory such as fusion and values. This study explored whether there was a relationship between two of the main ACT processes (cognitive defusion and values) and levels of depression and distress. Thirty-three participants completed questionnaires at the start and end of their treatment measuring general mental health and distress, depression, levels of cognitive fusion and how much they were living in line with their values and how important their values were to them. Results showed reductions in levels of fusion and increases in values-based action were significantly related to reductions in distress and depression. There was no correlation between changes in values importance and changes in distress or depression. This study therefore suggests decreased defusion and increased values-based action is an important mechanism in the efficacy of ACT in those with depression and mental health problems. The study is however limited by a small sample size and future research with a sample large enough for mediation analysis would be beneficial.

Acceptance Probability (P a) Analysis for Process Validation Lifecycle Stages.

This paper introduces an innovative statistical approach towards understanding how variation impacts the acceptance criteria of quality attributes. Because of more complex stage-wise acceptance criteria, traditional process capability measures are inadequate for general application in the pharmaceutical industry. The probability of acceptance concept provides a clear measure, derived from specific acceptance criteria for each quality attribute. In line with the 2011 FDA Guidance, this approach systematically evaluates data and scientifically establishes evidence that a process is capable of consistently delivering quality product. The probability of acceptance provides a direct and readily understandable indication of product risk. As with traditional capability indices, the acceptance probability approach assumes that underlying data distributions are normal. The computational solutions for dosage uniformity and dissolution acceptance criteria are readily applicable. For dosage uniformity, the expected AV range may be determined using the s lo and s hi values along with the worst case estimates of the mean. This approach permits a risk-based assessment of future batch performance of the critical quality attributes. The concept is also readily applicable to sterile/non sterile liquid dose products. Quality attributes such as deliverable volume and assay per spray have stage-wise acceptance that can be converted into an acceptance probability. Accepted statistical guidelines indicate processes with C pk > 1.33 as performing well within statistical control and those with C pk < 1.0 as "incapable" (1). A C pk > 1.33 is associated with a centered process that will statistically produce less than 63 defective units per million. This is equivalent to an acceptance probability of >99.99%.

The two study sites are comprised of three coal-fired electrical generating units (EGUs) located in southwest Indiana. The sites are characterized by tall, buoyant stacks,flat terrain, multiple SO2 monitors, and relatively isolated locations. AERMOD v12060 and AERMOD v12345 with BETA options were evaluated at each study site. For the six monitor-receptor pairs evaluated, AERMOD showed generally good agreement with monitor values for the hourly 99th percentile SO2 design value, with design value ratios that ranged from 0.92 to 1.99. AERMOD was within acceptable performance limits for the Robust Highest Concentration (RHC) statistic (RHC ratios ranged from 0.54 to 1.71) at all six monitors. Analysis of the top 5% of hourly concentrations at the six monitor-receptor sites, paired in time and space, indicated poor model performance in the upper concentration range. The amount of hourly model predicted data that was within a factor of 2 of observations at these higher concentrations ranged from 14 to 43% over the six sites. Analysis of subsets of data showed consistent overprediction during low wind speed and unstable meteorological conditions, and underprediction during stable, low wind conditions. Hourly paired comparisons represent a stringent measure of model performance; however given the potential for application of hourly model predictions to the SO2 NAAQS design value, this may be appropriate. At these two sites, AERMOD v12345 BETA options do not improve model performance. A regulatory evaluation of AERMOD utilizing quantile-quantile (Q-Q) plots, the RHC statistic, and 99th percentile design value concentrations indicates that model performance is acceptable according to widely accepted regulatory performance limits. However, a scientific evaluation examining hourly paired monitor and model values at concentrations of interest indicates overprediction and underprediction bias that is outside of acceptable model performance measures. Overprediction of 1-hr SO2 concentrations by AERMOD presents major ramifications for state and local permitting authorities when establishing emission limits.

Objectives and importance of study: Yoga improves balance and mobility, and therefore has potential as a fall prevention strategy, yet its validity for preventing falls has not been established. The Otago Exercise Programme (OEP) and tai chi are proven to prevent falls. This study aimed to evaluate the perceptions and preferences of older people towards a yoga-based program with potential to decrease falls, to compare these perceptions to the views expressed about the OEP and tai chi, and to identify participant characteristics associated with a preference for the yoga program. Survey. Participants were 235 community-dwellers aged 60 years or older who were not participating or had not previously participated (within the past 10 years) in yoga-based exercise. Participants completed a self-report survey measuring demographics, physical activity level and attitude. They then viewed explanations of the yoga-based program, the OEP and tai chi. Participants completed the Attitudes to Falls-Related Interventions Scale (AFRIS) to measure program acceptability and identified their preferred program. Acceptability scores and preference were compared between the programs, and factors associated with yoga preference were identified with analysis of variance. The mean age of participants (69% female) was 69.4 years (standard deviation 7.4). All programs were rated as equally acceptable (p = 0.17), with AFRIS scores ranging from 28.1 to 29.4. Eighty-two people (35%) preferred yoga, 32% chose the OEP and 33% chose tai chi. Overall, people who preferred yoga were significantly younger, healthier, less fearful of falling, and perceived exercise more positively than people who preferred the OEP (p values ranged from 0.03 to <0.001). The characteristics of people who preferred yoga and those who preferred tai chi did not vary significantly. Yoga was perceived to be appropriate and was as popular as two validated fall prevention programs. Yoga warrants further investigation as a fall prevention strategy, particularly for 'younger' and healthier people aged 60 years or older.

As publishing is essential but competitive for researchers, difficulties in writing and submitting medical articles to biomedical journals are disabling. The DIAzePAM (Difficultés des Auteurs à la Publication d'Articles Médicaux) survey aimed to assess the difficulties experienced by researchers in the AP-HP (Assistance Publique - Hôpitaux de Paris, i.e., Paris Hospitals Board, France), the largest public health institution in Europe, when preparing articles for biomedical journals. The survey also aimed to assess researchers' satisfaction and perceived needs. A 39-item electronic questionnaire based on qualitative interviews was addressed by e-mail to all researchers registered in the AP-HP SIGAPS (Système d'Interrogation, de Gestion et d'Analyse des Publications Scientifiques) bibliometric database. Between 28 May and 15 June 2015, 7766 researchers should have received and read the e-mail, and 1191 anonymously completed the questionnaire (<45 years of age: 63%; women: 55%; physician: 81%; with PhD or Habilitation à Diriger des recherches--accreditation to direct research--: 45%). 94% of respondents had published at least one article in the previous 2 years. 76% of respondents felt they were not publishing enough, mainly because of lack of time to write (79%) or submit (27%), limited skills in English (40%) or in writing (32%), and difficulty in starting writing (35%). 87% of respondents would accept technical support, especially in English reediting (79%), critical reediting (63%), formatting (52%), and/or writing (41%), to save time (92%) and increase high-impact-factor journal submission and acceptance (75%). 79% of respondents would appreciate funding support for their future publications, for English reediting (56%), medical writing (21%), or publication (38%) fees. They considered that this funding support could be covered by AP-HP (73%) and/or by the added financial value obtained by their department from previous publications (56%). The DIAzePAM survey highlights difficulties experienced by researchers preparing articles for biomedical journals, and details room for improvement.

Diffusion-weighted imaging and fluorine-18-fluorodeoxyglucose PET are increasingly being recognized as feasible oncological techniques. The apparent diffusion coefficient (ADC) measured by diffusion-weighted imaging and the standardized uptake value (SUV) from fluorine-18-fluorodeoxyglucose PET have similar clinical applications. The aim of this study was to assess the correlation between these two parameters in various cancers. Several major databases were searched for eligible studies. The correlation coefficient (ρ) values were pooled in a random-effects model. Begg's test was used to analyze the existence of publication bias and the sources of heterogeneity were explored in subgroup analyses on the basis of study design, diagnostic method, scanning modality, and tumor type. Thirty-five articles were accepted. The pooled ρ value of all of the accepted studies was -0.30 (95% confidence interval: -0.33 to -0.27), and notable heterogeneity was present (I=69.4%, P<0.001), which indicated a relatively weak negative correlation. The pooled ρ values were -0.26, -0.33, -0.32, and -0.33 for the SUVmax/ADCmean, SUVmax/ADCmin, SUVmean/ADCmean, and SUVmean/ADCmin relationships, respectively. The study design and diagnostic method were potential sources of heterogeneity. Lung cancer showed a stronger correlation (ρ=-0.42) than head and neck cancer (ρ=-0.27), cervical cancer (ρ=-0.21), and breast cancer (ρ=-0.23). A Begg's test indicated no significant publication bias among the accepted studies (P>0.05). The two functional parameters of ADC and SUV showed a very weak inverse correlation, which may contribute toward a sophisticated characterization of tumor biology. However, the findings require further validation with trials with large samples and different tumor types.

To evaluate inter-rater and intra-rater agreement on the Nordic Orofacial Test-Screening (NOT-S) examination applied to children, adolescents and young adults with cerebral palsy (CP). Using the NOT-S examination, two speech and language pathologists independently assessed video recordings of 48 subjects with CP aged 5-22 years and representing all CP sub-diagnoses and levels of gross motor function and manual ability. Thirty-one subjects were reassessed. Fifteen out of 17 items in the NOT-S examination domains (1) Face at rest, (2) Nose breathing, (3) Facial expression, (4) Masticatory muscle and jaw function, (5) Oral motor function and (6) Speech were rated using a 'yes' (dysfunction observed)/'no' format, generating an overall score of 0-6. Inter-rater agreement: Twelve out of 15 items and five out of six domains showed acceptable unweighted kappa values (κ = 0.46-1.00). The lowest kappa value was found for domain 4 (κ = -0.04), although it had high inter-rater agreement (92%). The linear weighted kappa value for the overall NOT-S examination score was 0.65 (95% CI = 0.49-0.82). Intra-rater agreement: All items and domains showed acceptable unweighted kappa values (items 0.58-1.00 and 0.59-1.00, domains 0.81-1.00 and 0.62-0.89) for both raters. The linear weighted kappa value for the overall NOT-S examination score was 0.81 (95% CI = 0.63-0.99) for rater A and 0.54 (95% CI = 0.25-0.82) for rater B. The NOT-S examination has acceptable inter-rater and intra-rater agreement when used in young individuals with CP.

Background Wearable activity trackers are newly emerging technologies with the anticipation for successfully supporting aging-in-place. Consumer-grade wearable activity trackers are increasingly ubiquitous in the market, but the attitudes toward, as well as acceptance and voluntary use of, these trackers in older population are poorly understood. Objective The aim of this study was to assess acceptance and usage of wearable activity trackers in Canadian community-dwelling older adults, using the potentially influential factors as identified in literature and technology acceptance model. Methods A mixed methods design was used. A total of 20 older adults aged 55 years and older were recruited from Southwestern Ontario. Participants used 2 different wearable activity trackers (Xiaomi Mi Band and Microsoft Band) separately for each segment in the crossover design study for 21 days (ie, 42 days total). A questionnaire was developed to capture acceptance and experience at the end of each segment, representing 2 different devices. Semistructured interviews were conducted with 4 participants, and a content analysis was performed. Results Participants ranged in age from 55 years to 84 years (mean age: 64 years). The Mi Band gained higher levels of acceptance (16/20, 80%) compared with the Microsoft Band (10/20, 50%). The equipment characteristics dimension scored significantly higher for the Mi Band (P<.05). The amount a participant was willing to pay for the device was highly associated with technology acceptance (P<.05). Multivariate logistic regression with 3 covariates resulted in an area under the curve of 0.79. Content analysis resulted in the formation of the following main themes: (1) smartphones as facilitators of wearable activity trackers; (2) privacy is less of a concern for wearable activity trackers, (3) value proposition: self-awareness and motivation; (4) subjective norm, social support, and sense of independence; and (5) equipment characteristics matter: display, battery, comfort, and aesthetics. Conclusions Older adults were mostly accepting of wearable activity trackers, and they had a clear understanding of its value for their lives. Wearable activity trackers were uniquely considered more personal than other types of technologies, thereby the equipment characteristics including comfort, aesthetics, and price had a significant impact on the acceptance. Results indicated that privacy was less of concern for older adults, but it may have stemmed from a lack of understanding of the privacy risks and implications. These findings add to emerging research that investigates acceptance and factors that may influence acceptance of wearable activity trackers among older adults. PMID:29141837

Insects have long been consumed as part of the diets of many Asian, African, and South American cultures. However, despite international agencies such as the Food and Agriculture Organization of the United Nations advocating the nutritional, environmental, and economic benefits of entomophagy, attitudinal barriers persist in Western societies. In Australia, the indigenous ‘bush tucker’ diet comprising witchetty grubs, honey ants, and Bogong moths is quite well known; however, in most Australian locales, the consumption of insects tends to occur only as a novelty. Therefore, this study aimed to investigate the awareness and acceptance of insects as food. An online survey of 820 consumers found that 68% of participants had heard of entomophagy, but only 21% had previously eaten insects; witchetty grubs, ants, grasshoppers, and crickets were the most commonly tasted insects. Taste, appearance, safety, and quality were identified as the factors that were most likely to influence consumer willingness to try eating insects, but consumer attitudes towards entomophagy were underpinned by both food neophobia (i.e., reluctance to eat new or novel foods) and prior consumption of insects. Neophobic consumers were far less accepting of entomophagy than neophilic consumers, while consumers who had previously eaten insects were most accepting of insects as food. Incorporating insects into familiar products (e.g., biscuits) or cooked meals also improved their appeal. Collectively, these findings can be used by the food industry to devise production and/or marketing strategies that overcome barriers to insect consumption in Australia.

Opt out antenatal HIV testing has significantly reduced mother to child transmission of HIV, but seroconversion during pregnancy from undiagnosed HIV positive male partners remains a risk. The authors report on a pilot initiative for sexual health and HIV screening for male partners of women attending antenatal ultrasound examination at Homerton Hospital, London. Men attending with their female partners for routine ultrasound examination between 1 August 2010 and 31 January 2011 were offered on-site serology for HIV, syphilis, hepatitis B and hepatitis C and urine testing for Neiserria gonorrhoeae and Chlamydia trachomatis. were followed up through the genitourinary medicine service. Referral pathways were established for men with positive results. 1243 male partners of 2400 women attended ultrasound examinations, of whom 430 accepted testing (acceptance rate 35% and coverage rate 18%). Median age was 32 years (range 19-52). 112/430 (26%) male partners were of black ethnicity. 41% had previously had a HIV test. There was no difference in prior HIV testing between whites and non-whites. 16 infections were diagnosed, including two cases of hepatitis C, eight cases of hepatitis B and six cases of C trachomatis. No HIV diagnoses were made. The authors have shown that it is acceptable and feasible to engage heterosexual men for testing in this setting. Of those men who accepted HIV testing, more than half had never been previously tested. 4% of men tested had an infection, which had the potential to affect the outcome of the pregnancy.

Postpartum Depression (PPD) is a known entity affecting not only the women but the whole family. It affects women more harshly and chronically due to their increased stress sensitivity, maladaptive coping strategies and multiple social roles in the community. To estimate the commonly associated risk factors of PPD among the women coming to a tertiary hospital in New Delhi, India. It was a longitudinal study conducted at the antenatal clinic for a period of one year. Total 260 women were screened at > 36 weeks of gestation, of which 149 postnatal women completed the questionnaire for PPD at six weeks of their delivery. The inform consent, demographical data and obstetrical details from each participant was taken before commencing the screening. Various risk factors and their association were determined by odds-ratio and significant association was accepted at < 5% level of error. In order to identify the most important confounding variables, logistic regression analysis was used. PPD is a common mental health problem seen among the postnatal women as it was found in 12.75% (19 out of 149) of subjects at six weeks of their delivery. Moreover, it has significant association with the young maternal age (p-value=0.040), birth of the female child (p-value=0.015), previous stressful life events (p-value= 0.003), low self-esteem and feeling of loneliness (p-value=0.007). This study provides important information regarding the risk factors associated with development of PPD in this region of India. Female sex of the new born and the younger age play an important role in the development of PPD.

To predict the three-dimensional dose distribution of our total body irradiation technique, using a commercial treatment planning system (TPS). In vivo dosimetry, using metal oxide field effect transistors (MOSFETs) and thermoluminescence detectors (TLDs), was used to verify the calculated dose distributions. A total body computed tomography scan was performed and loaded into our TPS, and a three-dimensional-dose distribution was generated. In vivo dosimetry was performed at five locations on the patient. Entrance and exit dose values were converted to midline doses using conversion factors, previously determined with phantom measurements. The TPS-predicted dose values were compared with the MOSFET and TLD in vivo dose values. The MOSFET and TLD dose values agreed within 3.0% and the MOSFET and TPS data within 0.5%. The convolution algorithm of the TPS, which is routinely applied in the clinic, overestimated the dose in the lung region. Using a superposition algorithm reduced the calculated lung dose by approximately 3%. The dose inhomogeneity, as predicted by the TPS, can be reduced using a simple intensity-modulated radiotherapy technique. The use of a TPS to calculate the dose distributions in individual patients during total body irradiation is strongly recommended. Using a TPS gives good insight of the over- and underdosage in a patient and the influence of patient positioning on dose homogeneity. MOSFETs are suitable for in vivo dosimetry purposes during total body irradiation, when using appropriate conversion factors. The MOSFET, TLD, and TPS results agreed within acceptable margins.
