  1. Discriminating binding mechanisms of an intrinsically disordered protein via a multi-state coarse-grained model

    Knott, Michael; Best, Robert B.


    Many proteins undergo a conformational transition upon binding to their cognate binding partner, with intrinsically disordered proteins (IDPs) providing an extreme example in which a folding transition occurs. However, it is often not clear whether this occurs via an “induced fit” or “conformational selection” mechanism, or via some intermediate scenario. In the first case, transient encounters with the binding partner favour transitions to the bound structure before the two proteins dissociate, while in the second the bound structure must be selected from a subset of unbound structures which are in the correct state for binding, because transient encounters of the incorrect conformation with the binding partner are most likely to result in dissociation. A particularly interesting situation involves those intrinsically disordered proteins which can bind to different binding partners in different conformations. We have devised a multi-state coarse-grained simulation model which is able to capture the binding of IDPs in alternate conformations, and by applying it to the binding of nuclear coactivator binding domain (NCBD) to either ACTR or IRF-3 we are able to determine the binding mechanism. By all measures, the binding of NCBD to either binding partner appears to occur via an induced fit mechanism. Nonetheless, we also show how a scenario closer to conformational selection could arise by choosing an alternative non-binding structure for NCBD

    Full Text Available The paper presents three operative models whose purpose is to improve the practice of preventive maintenance to a wide range of technical installations. Although the calculation criteria are different, the goal is the same: to determine the optimum time between two consecutive preventive interventions. The optimum criteria of these models are: - the maximum share of technical entity operating probabilities, in the case of the Ackoff - Sasieni [1] method; -the optimum time interval for preventive verification depending on the preventive-corrective maintenance costs imposed by the deciding factor, for the AsturioBaldin [2] model; - the minimum number of renewals – preventive and/or corrective maintenance operations [3

  7. A coupled channel study on a binding mechanism of positronic alkali atoms

    International Nuclear Information System (INIS)

    Kubota, Yoshihiro; Kino, Yasushi


    In order to investigate the binding mechanism of weakly bound states of positronic alkali atoms, we calculate the energies and wavefunctions using the Gaussian expansion method (GEM) where a positronium (Ps)-alkali ion channel and a positron-alkali atom channel are explicitly introduced. The energies of the bound states are updated using a model potential that reproduces well the observed energy levels of alkali atoms. The binding mechanism of the positronic alkali atom is analyzed by the wavefunctions obtained. The structure of the positronic alkali atom has been regarded as a Ps cluster orbiting the alkali ion, which is described by the Ps-alkali ion channel. We point out that the fraction having the positron-alkali atom configuration is small but plays an indispensable role for the weakly bound system

  9. Hydraulic root water uptake models: old concerns and new insights (United States)

    Couvreur, V.; Carminati, A.; Rothfuss, Y.; Meunier, F.; Vanderborght, J.; Javaux, M.


    Root water uptake (RWU) affects underground water dynamics, with consequences on plant water availability and groundwater recharge. Even though hydrological and climate models are sensitive to RWU parameters, no consensus exists on the modelling of this process. Back in the 1940ies, Van Den Honert's catenary approach was the first to investigate the use of connected hydraulic resistances to describe water flow in whole plants. However concerns such as the necessary computing when architectures get complex made this approach premature. Now that computing power increased dramatically, hydraulic RWU models are gaining popularity, notably because they naturally produce observed processes like compensatory RWU and hydraulic redistribution. Yet major concerns remain. Some are more fundamental: according to hydraulic principles, plant water potential should equilibrate with soil water potential when the plant does not transpire, which is not a general observation when using current definitions of bulk or average soil water potential. Other concerns regard the validation process: water uptake distribution is not directly measurable, which makes it hard to demonstrate whether or not hydraulic models are more accurate than other models. Eventually parameterization concerns exist: root hydraulic properties are not easily measurable, and would even fluctuate on an hourly basis due to processes like aquaporin gating. While offering opportunities to validate hydraulic RWU models, newly developed observation techniques also make us realize the increasing complexity of processes involved in soil-plant hydrodynamics, such as the change of rhizosphere hydraulic properties with soil drying. Surprisingly, once implemented into hydraulic models, these processes do not necessarily translate into more complex emerging behavior at plant scale, and might justify the use of simplified representations of the soil-plant hydraulic system.

  11. Modelling information dissemination under privacy concerns in social media (United States)

    Zhu, Hui; Huang, Cheng; Lu, Rongxing; Li, Hui


    Social media has recently become an important platform for users to share news, express views, and post messages. However, due to user privacy preservation in social media, many privacy setting tools are employed, which inevitably change the patterns and dynamics of information dissemination. In this study, a general stochastic model using dynamic evolution equations was introduced to illustrate how privacy concerns impact the process of information dissemination. Extensive simulations and analyzes involving the privacy settings of general users, privileged users, and pure observers were conducted on real-world networks, and the results demonstrated that user privacy settings affect information differently. Finally, we also studied the process of information diffusion analytically and numerically with different privacy settings using two classic networks.

  12. Computational Study of the Binding Mechanism of Actin-Depolymerizing Factor 1 with Actin in Arabidopsis thaliana.

    Directory of Open Access Journals (Sweden)

    Juan Du

    Full Text Available Actin is a highly conserved protein. It plays important roles in cellular function and exists either in the monomeric (G-actin or polymeric form (F-actin. Members of the actin-depolymerizing factor (ADF/cofilin protein family bind to both G-actin and F-actin and play vital roles in actin dynamics by manipulating the rates of filament polymerization and depolymerization. It has been reported that the S6D and R98A/K100A mutants of actin-depolymerizing factor 1 (ADF1 in Arabidopsis thaliana decreased the binding affinity of ADF for the actin monomer. To investigate the binding mechanism and dynamic behavior of the ADF1-actin complex, we constructed a homology model of the AtADF1-actin complex based on the crystal structure of AtADF1 and the twinfilin C-terminal ADF-H domain in a complex with a mouse actin monomer. The model was then refined for subsequent molecular dynamics simulations. Increased binding energy of the mutated system was observed using the Molecular Mechanics Generalized Born Surface Area and Poisson-Boltzmann Surface Area (MM-GB/PBSA methods. To determine the residues that make decisive contributions to the ADF1 actin-binding affinity, per-residue decomposition and computational alanine scanning analyses were performed, which provided more detailed information on the binding mechanism. Root-mean-square fluctuation and principal component analyses confirmed that the S6D and R98A/K100A mutants induced an increased conformational flexibility. The comprehensive molecular insight gained from this study is of great importance for understanding the binding mechanism of ADF1 and G-actin.

  13. The binding mechanism of a peptidic cyclic serine protease inhibitor

    Jiang, Longguang; Svane, Anna Sigrid P.; Sørensen, Hans Peter


    Serine proteases are classical objects for studies of catalytic and inhibitory mechanisms as well as interesting as therapeutic targets. Since small-molecule serine protease inhibitors generally suffer from specificity problems, peptidic inhibitors, isolated from phage-displayed peptide libraries......, have attracted considerable attention. Here, we have investigated the mechanism of binding of peptidic inhibitors to serine protease targets. Our model is upain-1 (CSWRGLENHRMC), a disulfide-bond-constrained competitive inhibitor of human urokinase-type plasminogen activator with a noncanonical...... inhibitory mechanism and an unusually high specificity. Using a number of modified variants of upain-1, we characterised the upain-1-urokinase-type plasminogen activator complex using X-ray crystal structure analysis, determined a model of the peptide in solution by NMR spectroscopy, and analysed binding...

  14. Binding mechanism and dynamic conformational change of C subunit of PKA with different pathways. (United States)

    Chu, Wen-Ting; Chu, Xiakun; Wang, Jin


    The catalytic subunit of PKA (PKAc) exhibits three major conformational states (open, intermediate, and closed) during the biocatalysis process. Both ATP and substrate/inhibitor can effectively induce the conformational changes of PKAc from open to closed states. Aiming to explore the mechanism of this allosteric regulation, we developed a coarse-grained model and analyzed the dynamics of conformational changes of PKAc during binding by performing molecular dynamics simulations for apo PKAc, binary PKAc (PKAc with ATP, PKAc with PKI), and ternary PKAc (PKAc with ATP and PKI). Our results suggest a mixed binding mechanism of induced fit and conformational selection, with the induced fit dominant. The ligands can drive the movements of Gly-rich loop as well as some regions distal to the active site in PKAc and stabilize them at complex state. In addition, there are two parallel pathways (pathway with PKAc-ATP as an intermediate and pathway PKAc-PKI as an intermediate) during the transition from open to closed states. By molecular dynamics simulations and rate constant analyses, we find that the pathway through PKAc-ATP intermediate is the main binding route from open to closed state because of the fact that the bound PKI will hamper ATP from successful binding and significantly increase the barrier for the second binding subprocess. These findings will provide fundamental insights of the mechanisms of PKAc conformational change upon binding.

  17. A model problem concerning ionic transport in microstructured solid electrolytes (United States)

    Curto Sillamoni, Ignacio J.; Idiart, Martín I.


    We consider ionic transport by diffusion and migration through microstructured solid electrolytes. The assumed constitutive relations for the constituent phases follow from convex energy and dissipation potentials which guarantee thermodynamic consistency. The effective response is determined by homogenizing the relevant field equations via the notion ofmulti-scale convergence. The resulting homogenized response involves several effective tensors, but they all require the solution of just one standard conductivity problem over the representative volume element. A multi-scale model for semicrystalline polymer electrolytes with spherulitic morphologies is derived by applying the theory to a specific class of two-dimensional microgeometries for which the effective response can be computed exactly. An enriched model accounting for a random dispersion of filler particles with interphases is also derived. In both cases, explicit expressions for the effective material parameters are provided. The models are used to explore the effect of crystallinity and filler content on the overall response. Predictions support recent experimental observations on doped poly-ethylene-oxide systems which suggest that the anisotropic crystalline phase can actually support faster ion transport than the amorphous phase along certain directions dictated by the morphology of the polymeric chains. Predictions also support the viewpoint that ceramic fillers improve ionic conductivity and cation transport number via interphasial effects.

  18. Concerning modeling of double-stage water evaporation cooling (United States)

    Shatskiy, V. P.; Fedulova, L. I.; Gridneva, I. V.


    The matter of need for setting technical norms for production, as well as acceptable microclimate parameters, such as temperature and humidity, at the work place, remains urgent. Use of certain units should be economically sound and that should be taken into account for construction, assembly, operation, technological, and environmental requirements. Water evaporation coolers are simple to maintain, environmentally friendly, and quite cheap, but the development of the most efficient solutions requires mathematical modeling of the heat and mass transfer processes that take place in them.

  19. An illustration of the Arena model: Conflicts concerning nuclear energy

    International Nuclear Information System (INIS)

    Renn, O.


    The author examines the current relevance of the debate on risk and presents a systematic survey of theoretical concepts of risk: Technical foundations, economic and psychological perspectives, sociological and cultural-anthropological perspectives as well as social mobilization and the arena model, arenas for settling conflicts being parliament, administrative institutions, the legal realm, the humanities and sciences, mass media etc. The arena model is illustrated using atomic energy as an example, whereby the following factors are taken into account: The political arena, the function of the normal authority, agents, the media as a medium for action and public opinion. Conclusion: Three elements are necessary for a rational and democratic policy for dealing with risks: Experts on the theoretical aspects of the issue must be consulted, the legitimate interests of those persons in the arena who are affected by the decision must be taken into acoount and a representative public opinion poll which determines whether the public is in favour of possible political options must be carried out, thus giving them the opportunity to participate in the decision-making procedure. The better a process is prestructured before such a participatory procedure is initiated, the more likely it is that acceptance and acceptability can be obtained. (orig./HSCH) [de

  20. Insights on Structural Characteristics and Ligand Binding Mechanisms of CDK2

    Directory of Open Access Journals (Sweden)

    Yan Li


    Full Text Available Cyclin-dependent kinase 2 (CDK2 is a crucial regulator of the eukaryotic cell cycle. However it is well established that monomeric CDK2 lacks regulatory activity, which needs to be aroused by its positive regulators, cyclins E and A, or be phosphorylated on the catalytic segment. Interestingly, these activation steps bring some dynamic changes on the 3D-structure of the kinase, especially the activation segment. Until now, in the monomeric CDK2 structure, three binding sites have been reported, including the adenosine triphosphate (ATP binding site (Site I and two non-competitive binding sites (Site II and III. In addition, when the kinase is subjected to the cyclin binding process, the resulting structural changes give rise to a variation of the ATP binding site, thus generating an allosteric binding site (Site IV. All the four sites are demonstrated as being targeted by corresponding inhibitors, as is illustrated by the allosteric binding one which is targeted by inhibitor ANS (fluorophore 8-anilino-1-naphthalene sulfonate. In the present work, the binding mechanisms and their fluctuations during the activation process attract our attention. Therefore, we carry out corresponding studies on the structural characterization of CDK2, which are expected to facilitate the understanding of the molecular mechanisms of kinase proteins. Besides, the binding mechanisms of CDK2 with its relevant inhibitors, as well as the changes of binding mechanisms following conformational variations of CDK2, are summarized and compared. The summary of the conformational characteristics and ligand binding mechanisms of CDK2 in the present work will improve our understanding of the molecular mechanisms regulating the bioactivities of CDK2.

  1. Two Differential Binding Mechanisms of FG-Nucleoporins and Nuclear Transport Receptors

    Directory of Open Access Journals (Sweden)

    Piau Siong Tan


    Full Text Available Summary: Phenylalanine-glycine-rich nucleoporins (FG-Nups are intrinsically disordered proteins, constituting the selective barrier of the nuclear pore complex (NPC. Previous studies showed that nuclear transport receptors (NTRs were found to interact with FG-Nups by forming an “archetypal-fuzzy” complex through the rapid formation and breakage of interactions with many individual FG motifs. Here, we use single-molecule studies combined with atomistic simulations to show that, in sharp contrast, FG-Nup214 undergoes a coupled reconfiguration-binding mechanism when interacting with the export receptor CRM1. Association and dissociation rate constants are more than an order of magnitude lower than in the archetypal-fuzzy complex between FG-Nup153 and NTRs. Unexpectedly, this behavior appears not to be encoded selectively into CRM1 but rather into the FG-Nup214 sequence. The same distinct binding mechanisms are unperturbed in O-linked β-N-acetylglucosamine-modified FG-Nups. Our results have implications for differential roles of distinctly spatially distributed FG-Nup⋅NTR interactions in the cell. : Archetypal-fuzzy complexes found in most FG-Nucleoporin⋅nuclear transport receptor complexes allow fast yet specific nuclear transport. Tan et al. show that FG-Nup214, located at the periphery of the nuclear pore complex, binds to CRM1⋅RanGTP via a coupled reconfiguration-binding mechanism, which can enable different functionalities e.g., cargo release. Keywords: intrinsically disordered protein, glycosylation, FG-Nup, nuclear transport receptors, binding mechanism, single-molecule FRET, molecular dynamics simulations

  3. DNA-cisplatin binding mechanism peculiarities studied with single molecule stretching experiments (United States)

    Crisafuli, F. A. P.; Cesconetto, E. C.; Ramos, E. B.; Rocha, M. S.


    We propose a method to determine the DNA-cisplatin binding mechanism peculiarities by monitoring the mechanical properties of these complexes. To accomplish this task, we have performed single molecule stretching experiments by using optical tweezers, from which the persistence and contour lengths of the complexes can be promptly measured. The persistence length of the complexes as a function of the drug total concentration in the sample was used to deduce the binding data, from which we show that cisplatin binds cooperatively to the DNA molecule, a point which so far has not been stressed in binding equilibrium studies of this ligand.

  5. Modelling categorical data to identify factors influencing concern for the natural environment in Iran. (United States)

    Parizanganeh, Abdolhossein; Lakhan, V Chris; Yazdani, Mahmoud; Ahmad, Sajid R


    Loglinear modelling techniques were used to identify the interactions and interrelationships underlying categorical environmental concern data collected from 9062 respondents in Iran. After fitting various loglinear models to the data, the most parsimonious model highlighted that a combination of interacting factors, namely educational attainment, age, gender, and residential location were responsible for influencing personal concern for the environment. Although high educational attainment had a close correspondence with high concern for the environment the loglinear results, when visualized with a geographical information system, demonstrated wide spatial variations in educational attainment and concern for the environment. Nearly two-thirds of the respondents were not highly educated, and were therefore not highly concerned for the environment. The finding that both rural and urban male and female respondents in the 15-24 years age category, with 10-12 years of education, had the strongest interaction with personal concern for the environment could be beneficial for policy planners to utilize education as the primary instrument to enhance environmental governance and prospects for sustainable development.

    Full Text Available The cases of accounting data manipulation that involve big firms, such as Enron and WorldCom, have affected auditor reputation. Enron and 95 other firms received unqualified opinion in the year prior to bankruptcy. This fact raises questions why firms receiving unqualified opinion stop operating. The assessment of going concern has to be delivered by auditor and added into audit opinion.  An auditor is responsible to evaluate whether there is substantial doubt about the entity’s ability to continue its operation for a reasonable period of time. This research aims to investigate the effect of bankruptcy prediction model, firm growth, leverage, and auditor reputation on going concern audit opinion. The result shows that bankruptcy prediction model affects the accuracy of going concern opinion issue. However, the firm growth, leverage, and auditor reputation do not do so.

  8. The Development of Empathic Concern in Siblings: A Reciprocal Influence Model. (United States)

    Jambon, Marc; Madigan, Sheri; Plamondon, André; Daniel, Ella; Jenkins, Jennifer M


    This study utilized actor-partner interdependence modeling to examine the bidirectional effects of younger (M age  = 18 months) and older siblings (M age  = 48 months) on later empathy development in a large (n = 452 families), diverse (42% immigrant) Canadian sample. Controlling for parenting, demographic characteristics, sibling relationship quality, and within-child stability in empathic concern, both younger and older siblings' observed empathic concern uniquely predicted relative increases in the other's empathy over a period of 18 months. The strength of the partner effects did not differ by birth order. Sex composition moderated the younger sibling partner effect, whereas age gap moderated the older sibling partner effect. This study highlights the important role that siblings play in enhancing the development of care and concern for others. © 2018 The Authors.

  9. Body image concerns in professional fashion models: are they really an at-risk group? (United States)

    Swami, Viren; Szmigielska, Emilia


    Although professional models are thought to be a high-risk group for body image concerns, only a handful of studies have empirically investigated this possibility. The present study sought to overcome this dearth of information by comparing professional models and a matched sample on key indices of body image and appeared-related concerns. A group of 52 professional fashion models was compared with a matched sample of 51 non-models from London, England, on indices of weight discrepancy, body appreciation, social physique anxiety, body dissatisfaction, drive for thinness, internalization of sociocultural messages about appearance, and dysfunctional investment in appearance. Results indicated that professional models only evidenced significantly higher drive for thinness and dysfunctional investment in appearance than the control group. Greater duration of engagement as a professional model was associated with more positive body appreciation but also greater drive for thinness. These results indicate that models, who are already underweight, have a strong desire to maintain their low body mass or become thinner. Taken together, the present results suggest that interventions aimed at promoting healthy body image among fashion models may require different strategies than those aimed at the general population.

  10. Using docking and alchemical free energy approach to determine the binding mechanism of eEF2K inhibitors and prioritizing the compound synthesis. (United States)

    Wang, Qiantao; Edupuganti, Ramakrishna; Tavares, Clint D J; Dalby, Kevin N; Ren, Pengyu


    A-484954 is a known eEF2K inhibitor with submicromolar IC50 potency. However, the binding mechanism and the crystal structure of the kinase remains unknown. Here, we employ a homology eEF2K model, docking and alchemical free energy simulations to probe the binding mechanism of eEF2K, and in turn, guide the optimization of potential lead compounds. The inhibitor was docked into the ATP-binding site of a homology model first. Three different binding poses, hypothesis 1, 2, and 3, were obtained and subsequently applied to molecular dynamics (MD) based alchemical free energy simulations. The calculated relative binding free energy of the analogs of A-484954 using the binding pose of hypothesis 1 show a good correlation with the experimental IC50 values, yielding an r (2) coefficient of 0.96 after removing an outlier (compound 5). Calculations using another two poses show little correlation with experimental data, (r (2) of less than 0.5 with or without removing any outliers). Based on hypothesis 1, the calculated relative free energy suggests that bigger cyclic groups, at R1 e.g., cyclobutyl and cyclopentyl promote more favorable binding than smaller groups, such as cyclopropyl and hydrogen. Moreover, this study also demonstrates the ability of the alchemical free energy approach in combination with docking and homology modeling to prioritize compound synthesis. This can be an effective means of facilitating structure-based drug design when crystal structures are not available.

    Ryynaenen, S.; Naett, H.; Valkonen, J.


    The TTS-Institute's Forestry Department has developed a computer-based cost calculation model for the production of wood chips and split firewood. This development work was carried out in conjunction with the nation-wide BIOENERGY -research programme. The said calculation model eases and speeds up the calculation of unit costs and resource needs in harvesting systems for wood chips and split firewood. The model also enables the user to find out how changes in the productivity and costs bases of different harvesting chains influences the unit costs of the system as a whole. The undertaking was composed of the following parts: clarification and modification of productivity bases for application in the model as mathematical models, clarification of machine and device costs bases, designing of the structure and functions of the calculation model, construction and testing of the model's 0-version, model calculations concerning typical chains, review of calculation bases, and charting of development needs focusing on the model. The calculation model was developed to serve research needs, but with further development it could be useful as a tool in forestry and agricultural extension work, related schools and colleges, and in the hands of firewood producers.

    The study was carried out concerning environmental factors and social hygienic portrait of rural residents. The analysis determined environmental, social and behavioral risk factors of health. The pathologies of risk for rural residents were substantiated. In conditions of degradation of accessibility of medical care to inhabitants residing outside of district centers specified by decreasing of capacity of hospital medical care and decreasing of accessibility of out-patient services, the visiting trips of physicians ’ teams and activities concerning development of hygienic literacy were organized in 2012-2014. This approach permitted ameliorating health indices and organization of medical care for the given category of citizen, including positive results in decreasing of mortality, timely diagnostic of diseases, reduction of number of emergency operations in central district hospitals and attenuation of intensity of impact of regulative risk factors. All this determined in the upshot social and economic effectiveness of advanced model of prevention of health disorders of rural residents.

  14. Explanatory models concerning the effects of small-area characteristics on individual health. (United States)

    Voigtländer, Sven; Vogt, Verena; Mielck, Andreas; Razum, Oliver


    Material and social living conditions at the small-area level are assumed to have an effect on individual health. We review existing explanatory models concerning the effects of small-area characteristics on health and describe the gaps future research should try to fill. Systematic literature search for, and analysis of, studies that propose an explanatory model of the relationship between small-area characteristics and health. Fourteen studies met our inclusion criteria. Using various theoretical approaches, almost all of the models are based on a three-tier structure linking social inequalities (posited at the macro-level), small-area characteristics (posited at the meso-level) and individual health (micro-level). No study explicitly defines the geographical borders of the small-area context. The health impact of the small-area characteristics is explained by specific pathways involving mediating factors (psychological, behavioural, biological). These pathways tend to be seen as uni-directional; often, causality is implied. They may be modified by individual factors. A number of issues need more attention in research on explanatory models concerning small-area effects on health. Among them are the (geographical) definition of the small-area context; the systematic description of pathways comprising small-area contextual as well as compositional factors; questions of direction of association and causality; and the integration of a time dimension.

    Mackinnon, Sean P; Kehayes, Ivy-Lee L; Leonard, Kenneth E; Fraser, Ronald; Stewart, Sherry H


    Partner-specific perfectionistic concerns (PC) include concern over mistakes, self-criticism, and socially prescribed perfectionism as it pertains to one's partner. The social disconnection model proposes that PC influences well-being indirectly through interpersonal problems. Thus, we hypothesized that social negativity (expressed anger, hostility, and rejection) would mediate the relationship between dyadic PC and subjective well-being. Data from 203 romantic dyads (92.1% heterosexual) were collected using self-report surveys and a four-wave, 4-week longitudinal design. Participants were predominantly female (53.1%), young (M = 22.69 years), and Caucasian (82.3%). Data were analyzed using an actor-partner interdependence model with multilevel structural equation modeling. There were significant actor effects at the between-subjects and within-subjects levels, and significant partner effects for the relationship between PC and social negativity at the within-subject level. Social negativity mediated the relationships between PC and both negative affect and life satisfaction. However, positive affect was more weakly related to PC and social negativity. The social disconnection model was supported. PC was positively associated with one's own social negativity and evoked hostile behaviors from one's partner. Hostile, rejecting behaviors reduced the well-being of the actor, but not the partner. Results suggest perfectionism may be best understood within an interpersonal context. © 2016 Wiley Periodicals, Inc.

  16. The influence of maternal modeling on body image concerns and eating disturbances in preadolescent girls. (United States)

    Handford, Charlotte M; Rapee, Ronald M; Fardouly, Jasmine


    Research suggests that mothers may influence the development of body image concerns and eating disturbances in their daughters by modeling negative body image beliefs and unhealthy eating behaviors. However, the causal nature of that mode of influence is yet to be established. This study implemented an experimental design to examine the impact of mothers' modeling of negative comments about their own appearance and diet on their daughters' body image concerns and eating behaviors. Participants were 8-12 year old girls and their mothers (N = 50). While viewing thin-ideal magazine advertisements with their daughter, mothers were instructed to make either negative comments about their own weight, shape, and diet or to make no appearance or diet related comments. Daughters' levels of body esteem, body satisfaction, and eating attitudes were assessed pre- and post-manipulation, and their actual eating habits were measured post-manipulation. Girls whose mothers had made self-critical comments about their own appearance and diet reported lower body esteem, lower body satisfaction, more problematic eating attitudes, and ate significantly fewer sweets than girls whose mothers had not made self-critical comments. These results have implications for disordered eating prevention programs, suggesting that greater emphasis be placed on discouraging negative modeling behaviors among mothers.

  17. Lead inhibition of DNA-binding mechanism of Cys(2)His(2) zinc finger proteins. (United States)

    Hanas, J S; Rodgers, J S; Bantle, J A; Cheng, Y G


    The association of lead with chromatin in cells suggests that deleterious metal effects may in part be mediated through alterations in gene function. To elucidate if and how lead may alter DNA binding of cysteine-rich zinc finger proteins, lead ions were analyzed for their ability to alter the DNA binding mechanism of the Cys(2)His(2) zinc finger protein transcription factor IIIA (TFIIIA). As assayed by DNase I protection, the interaction of TFIIIA with the 50-bp internal control region of the 5S ribosomal gene was partially inhibited by 5 microM lead ions and completely inhibited by 10 to 20 microM lead ions. Preincubation of free TFIIIA with lead resulted in DNA-binding inhibition, whereas preincubation of a TFIIIA/5S RNA complex with lead did not result in DNA-binding inhibition. Because 5S RNA binds TFIIIA zinc fingers, this result is consistent with an inhibition mechanism via lead binding to zinc fingers. The complete loss of DNase I protection on the 5S gene indicates the mechanism of inhibition minimally involves the N-terminal fingers of TFIIIA. Inhibition was not readily reversible and occurred in the presence of an excess of beta-mercaptoethanol. Inhibition kinetics were fast, progressing to completion in approximately 5 min. Millimolar concentrations of sulfhydryl-specific arsenic ions were not inhibitory for TFIIIA binding. Micromolar concentrations of lead inhibited DNA binding by Sp1, another Cys(2)His(2) finger protein, but not by the nonfinger protein AP2. Inhibition of Cys(2)His(2) zinc finger transcription factors by lead ions at concentrations near those known to have deleterious physiological effects points to new molecular mechanisms for lead toxicity in promoting disease.

  18. Modeled de facto reuse and contaminants of emerging concern in drinking water source waters (United States)

    Nguyen, Thuy; Westerhoff, Paul; Furlong, Edward T.; Kolpin, Dana W.; Batt, Angela L.; Mash, Heath E.; Schenck, Kathleen M.; Boone, J. Scott; Rice, Jacelyn; Glassmeyer, Susan T.


    De facto reuse is the percentage of drinking water treatment plant (DWTP) intake potentially composed of effluent discharged from upstream wastewater treatment plants (WWTPs). Results from grab samples and a De Facto Reuse in our Nation's Consumable Supply (DRINCS) geospatial watershed model were used to quantify contaminants of emerging concern (CECs) concentrations at DWTP intakes to qualitatively compare exposure risks obtained by the two approaches. Between nine and 71 CECs were detected in grab samples. The number of upstream WWTP discharges ranged from 0 to >1,000; comparative de facto reuse results from DRINCS ranged from 80% during lower streamflows. Correlation between chemicals detected and DRINCS modeling results were observed, particularly DWTPs withdrawing from midsize water bodies. This comparison advances the utility of DRINCS to identify locations of DWTPs for future CEC sampling and treatment technology testing.

  19. Concerns over modeling and warning capabilities in wake of Tohoku Earthquake and Tsunami (United States)

    Showstack, Randy


    Improved earthquake models, better tsunami modeling and warning capabilities, and a review of nuclear power plant safety are all greatly needed following the 11 March Tohoku earthquake and tsunami, according to scientists at the European Geosciences Union's (EGU) General Assembly, held 3-8 April in Vienna, Austria. EGU quickly organized a morning session of oral presentations and an afternoon panel discussion less than 1 month after the earthquake and the tsunami and the resulting crisis at Japan's Fukushima nuclear power plant, which has now been identified as having reached the same level of severity as the 1986 Chernobyl disaster. Many of the scientists at the EGU sessions expressed concern about the inability to have anticipated the size of the earthquake and the resulting tsunami, which appears likely to have caused most of the fatalities and damage, including damage to the nuclear plant.

  20. High school science teachers' perceptions of telecommunications utilizing a Concerns-Based Adoption Model (CBAM) (United States)

    Slough, Scott Wayne

    The purpose of this study was to describe high school science teachers' perceptions of telecommunications. The data were collected through open-ended ethnographic interviews with 24 high school science teachers from five different high schools in a single suburban school district who had been in an emerging telecommunications-rich environment for two and one-half years. The interview protocol was adapted from Honey and Henriquez (1993), with the Concerns-Based Adoption Model (CBAM) (Bailey & Palsha, 1992) providing a conceptual framework for data analysis. For this study, the emerging telecommunications-rich environment included a district-wide infrastructure that had been in place for two and one-half years that included a secure district-wide Intranet, 24 network connections in each classroom, full Internet access from the network, four computers per classroom, and a variety of formal and informal professional development opportunities for teachers. Categories of results discussed include: (a) teacher's profession use of telecommuunications; (b) teachers' perceptions of student's use of telecommunications; (c) teachers' perceptions of barriers to the implementation of telecommunications; (d) teachers' perceptions of supporting conditions for the implementation of telecommunications; (e) teachers' perceptions of the effect of telecommunications on high school science instruction; (f) teachers' perceptions of the effect of telecommunications on student's learning in high school science; and (g) the demographic variables of the sex of the teacher, years of teaching experience, school assignment within the district, course assignment(s), and academic preparation. Implications discussed include: (a) telecommunications can be implemented successfully in a variety of high school science classrooms with adequate infrastructure support and sufficient professional development opportunities, including in classes taught by females and teachers who were not previously

  2. Waterfowl populations of conservation concern: learning from diverse challenges, models, and conservation strategies (United States)

    Austin, Jane E.; Slattery, Stuart; Clark, Robert G.


    There are 30 threatened or endangered species of waterfowl worldwide, and several sub-populations are also threatened. Some of these species occur in North America, and others there are also of conservation concern due to declining population trends and their importance to hunters. Here we review conservation initiatives being undertaken for several of these latter species, along with conservation measures in place in Europe, to seek common themes and approaches that could be useful in developing broad conservation guidelines. While focal species may vary in their life histories, population threats and geopolitical context, most conservation efforts have used a systematic approach to understand factors limiting populations and o identify possible management or policy actions. This approach generally includes a priori identification of plausible hypotheses about population declines or status, incorporation of hypotheses into conceptual or quantitative planning models, and the use of some form of structured decision making and adaptive management to develop and implement conservation actions in the face of many uncertainties. A climate of collaboration among jurisdictions sharing these birds is important to the success of a conservation or management programme. The structured conservation approach exemplified herein provides an opportunity to involve stakeholders at all planning stages, allows for all views to be examined and incorporated into model structures, and yields a format for improved communication, cooperation and learning, which may ultimately be one of the greatest benefits of this strategy.

  3. Animal models in biological and biomedical research - experimental and ethical concerns. (United States)

    Andersen, Monica L; Winter, Lucile M F


    Animal models have been used in experimental research to increase human knowledge and contribute to finding solutions to biological and biomedical questions. However, increased concern for the welfare of the animals used, and a growing awareness of the concept of animal rights, has brought a greater focus on the related ethical issues. In this review, we intend to give examples on how animals are used in the health research related to some major health problems in Brazil, as well as to stimulate discussion about the application of ethics in the use of animals in research and education, highlighting the role of National Council for the Control of Animal Experimentation (Conselho Nacional de Controle de Experimentação Animal - CONCEA) in these areas. In 2008, Brazil emerged into a new era of animal research regulation, with the promulgation of Law 11794, previously known as the Arouca Law, resulting in an increased focus, and rapid learning experience, on questions related to all aspects of animal experimentation. The law reinforces the idea that animal experiments must be based on ethical considerations and integrity-based assumptions, and provides a regulatory framework to achieve this. This review describes the health research involving animals and the current Brazilian framework for regulating laboratory animal science, and hopes to help to improve the awareness of the scientific community of these ethical and legal rules.

  4. Is BAMM Flawed? Theoretical and Practical Concerns in the Analysis of Multi-Rate Diversification Models. (United States)

    Rabosky, Daniel L; Mitchell, Jonathan S; Chang, Jonathan


    Bayesian analysis of macroevolutionary mixtures (BAMM) is a statistical framework that uses reversible jump Markov chain Monte Carlo to infer complex macroevolutionary dynamics of diversification and phenotypic evolution on phylogenetic trees. A recent article by Moore et al. (MEA) reported a number of theoretical and practical concerns with BAMM. Major claims from MEA are that (i) BAMM's likelihood function is incorrect, because it does not account for unobserved rate shifts; (ii) the posterior distribution on the number of rate shifts is overly sensitive to the prior; and (iii) diversification rate estimates from BAMM are unreliable. Here, we show that these and other conclusions from MEA are generally incorrect or unjustified. We first demonstrate that MEA's numerical assessment of the BAMM likelihood is compromised by their use of an invalid likelihood function. We then show that "unobserved rate shifts" appear to be irrelevant for biologically plausible parameterizations of the diversification process. We find that the purportedly extreme prior sensitivity reported by MEA cannot be replicated with standard usage of BAMM v2.5, or with any other version when conventional Bayesian model selection is performed. Finally, we demonstrate that BAMM performs very well at estimating diversification rate variation across the ${\\sim}$20% of simulated trees in MEA's data set for which it is theoretically possible to infer rate shifts with confidence. Due to ascertainment bias, the remaining 80% of their purportedly variable-rate phylogenies are statistically indistinguishable from those produced by a constant-rate birth-death process and were thus poorly suited for the summary statistics used in their performance assessment. We demonstrate that inferences about diversification rates have been accurate and consistent across all major previous releases of the BAMM software. We recognize an acute need to address the theoretical foundations of rate-shift models for

  5. Results of a modeling workshop concerning preservation and protection of wetlands in North Dakota (United States)

    Andrews, Austin K.; Auble, Gregor T.; Ellison, Richard A.; Hamilton, David B.; Roelle, James E.


    In a recently signed letter, the Governor of North Dakota and the Assistant Secretary of the Interior for Fish and Wildlife and Parks charged a joint state-federal study group with examination of two separate questions: 1) mitigation for the Garrison Diversion Project; and 2) planning for long-range protection and preservation of fish and wildlife habitat in North Dakota. The cochair for this study group (the Secretary of the Interior's Field Representative, Denver, Colorado, and the Natural Resources Coordinator for North Dakota) further articulated the charge concerning the second of these two questions to include three steps: 1) development of a general plan for preservation and protection of migratory waterfowl and their associated wetland habitat; 2) a comprehensive analysis of alternative strategies, including opportunities and constraints, for achieving the goals articulated in Step 1; and 3) design of a coordinated state-federal public information program to assist in plan implementation. In order to obtain input from a variety of interests, the joint study group initiated step 2 activities with a five-day workshop in Bismarck, N. D.; December 8-12, 1980. The objectives of the workshop were: 1) to identify alternative strategies for preserving and enhancing waterfowl production habitat in North Dakota; 2) to identify opportunities and constraints associated with those alternatives; and 3) to promote communication and understanding of the implications of those alternatives for all affected parties. To achieve these objectives, the workshop utilized a group of concepts and techniques collectively known as Adaptive Environmental Assessment (AEA). Developed by Dr. C. S. Holling and his co-workers at the University of British Columbia, the AEA process involves planners, managers, scientists, and other interested parties in a structures atmosphere whose focus is the construction and examination of a computerized simulation model of the resource system under

  6. Trans-Binding Mechanism of Ubiquitin-like Protein Activation Revealed by a UBA5-UFM1 Complex

    Directory of Open Access Journals (Sweden)

    Walaa Oweis


    Full Text Available Modification of proteins by ubiquitin or ubiquitin-like proteins (UBLs is a critical cellular process implicated in a variety of cellular states and outcomes. A prerequisite for target protein modification by a UBL is the activation of the latter by activating enzymes (E1s. Here, we present the crystal structure of the non-canonical homodimeric E1, UBA5, in complex with its cognate UBL, UFM1, and supporting biochemical experiments. We find that UBA5 binds to UFM1 via a trans-binding mechanism in which UFM1 interacts with distinct sites in both subunits of the UBA5 dimer. This binding mechanism requires a region C-terminal to the adenylation domain that brings UFM1 to the active site of the adjacent UBA5 subunit. We also find that transfer of UFM1 from UBA5 to the E2, UFC1, occurs via a trans mechanism, thereby requiring a homodimer of UBA5. These findings explicitly elucidate the role of UBA5 dimerization in UFM1 activation.

  7. Family characteristics and health behaviour as antecedents of school nurses' concerns about adolescents' health and development: a path model approach. (United States)

    Poutiainen, Hannele; Levälahti, Esko; Hakulinen-Viitanen, Tuovi; Laatikainen, Tiina


    Family socio-economic factors and parents' health behaviours have been shown to have an impact on the health and well-being of children and adolescents. Family characteristics have also been associated with school nurses' concerns, which arose during health examinations, about children's and adolescents' physical health and psychosocial development. Parental smoking has also been associated with smoking in adolescents. The aim of this study was to determine to what extent school nurses' concerns about adolescents' physical health and psychosocial development related to family characteristics are mediated through parents' and adolescents' own health behaviours (smoking). A path model approach using cross-sectional data was used. In 2008-2009, information about health and well-being of adolescents was gathered at health examinations of the Children's Health Monitoring Study. Altogether 1006 eighth and ninth grade pupils in Finland participated in the study. The associations between family characteristics, smoking among parents and adolescents and school nurses' concerns about adolescents' physical health and psychosocial development were examined using a structural equation model. Paternal education had a direct, and, through fathers' and boys' smoking, an indirect association with school nurses' concerns about the physical health of boys. Paternal labour market status and family income were only indirectly associated with concerns about the physical health of boys by having an effect on boys' smoking through paternal smoking, and a further indirect effect on concerns about boys' health. In girls, only having a single mother was strongly associated with school nurses' concerns about psychosocial development through maternal and adolescent girl smoking. Socio-economic family characteristics and parental smoking influence adolescent smoking and are associated with school nurses' concerns about adolescents' physical health and psychosocial development. The findings

  9. Molecular binding mechanisms of aqueous cadmium and lead to siderophores, bacteria and mineral surfaces (United States)

    Mishra, Bhoopesh

    Recent studies have shown that diverse groups of bacteria adsorb metals to similar extents and uptake can be modeled using a universal adsorption model. In this study, XAFS has been used to resolve whether binding sites determined for single species systems are responsible for adsorption in more complex natural bacterial assemblages. Results obtained from a series of XAFS experiments on pure Gram positive and Gram negative bacterial strains and consortia of bacteria as a function of pH and Cd loading suggests that every bacterial strain has a complex physiology and they are all slightly different from each other. Nevertheless from the metal adsorption chemistry point of view, the main difference between them lies in the site ratio of three fundamental sites only - carboxyl, phosphoryl and sulfide. Two completely different consortia of bacteria (obtained from natural river water, and soil system with severe organic contamination) were successfully modeled in the pH range 3.4--7.8 using the EXAFS models developed for single species systems. Results thus obtained can potentially have very high impact on the modeling of the complex bacterial systems in realistic geological settings, leading to further refinement and development of robust remediation strategies for metal contamination at macroscopic level. In another study, solution speciation of Pb and Cd with DFO-B has been examined using a combination of techniques (ICP, TOC, thermodynamic modeling and XAFS). Results indicate that Pb does not complex with DFO-B at all until about pH 3.5, but forms a totally caged structure at pH 7.5. At intermediate pH conditions, mixture of species (one and two hydroxamate groups complexed) is formed. Cd on the other hand, does not complex until pH 5, forms intermediate complexes at pH 8 and is totally chelated at pH 9. Further studies were conducted for Pb sorption to mineral surface kaolinite with and without DFO-B. In the absence of DFO-B, results suggest outer sphere and inner

    The crystal and solution structures of the T. thermophilus NlpC/P60 d, l-endopeptidase as well as the co-crystal structure of its N-terminal LysM domains bound to chitohexaose allow a proposal to be made regarding how the enzyme recognizes peptidoglycan. LysM domains, which are frequently present as repetitive entities in both bacterial and plant proteins, are known to interact with carbohydrates containing N-acetylglucosamine (GlcNAc) moieties, such as chitin and peptidoglycan. In bacteria, the functional significance of the involvement of multiple LysM domains in substrate binding has so far lacked support from high-resolution structures of ligand-bound complexes. Here, a structural study of the Thermus thermophilus NlpC/P60 endopeptidase containing two LysM domains is presented. The crystal structure and small-angle X-ray scattering solution studies of this endopeptidase revealed the presence of a homodimer. The structure of the two LysM domains co-crystallized with N-acetyl-chitohexaose revealed a new intermolecular binding mode that may explain the differential interaction between LysM domains and short or long chitin oligomers. By combining the structural information with the three-dimensional model of peptidoglycan, a model suggesting how protein dimerization enhances the recognition of peptidoglycan is proposed.

  11. It's all a matter of necessity and concern: A structural equation model of adherence to antihypertensive medication. (United States)

    Wilhelm, Marcel; Rief, Winfried; Doering, Bettina K


    Hypertension is often treated pharmacologically, yet adherence is poor. Beliefs about antihypertensive medicine, i.e., the necessity-concern framework (NCF), are valuable for explaining adherence. Therefore, a model structure is transferred from hypercholesterolemia to hypertension, assuming a mediating role of the NCF. Patients with hypertension (n=273) were surveyed online about demographics, health- and treatment-related factors, control beliefs, necessity and concern beliefs about their medication, and adherence. The data were analyzed using structural equation modeling (SEM). Necessity was positively (β=0.26, p=0.009) and concern was negatively (β=-0.51, p=0.020) associated with adherence. The NCF mediated the influence of background variables on adherence. Necessity was associated with comorbidity (β=-0.36, pConcern was associated with side effects (β=0.38, pconcern framework as a mediating factor was confirmed in hypertension, explaining more variance than previous approaches (23%). A personalized, emotionally supportive doctor-patient communication could be key to addressing beliefs about medicine and therefore to increasing adherence. Copyright © 2017 Elsevier B.V.

    An extensive computer model describing the mass balance and economic characteristics of radioactive waste disposal systems was exercised in a series of runs designed using linear statistical methods. The most economically important variables were identified, their behavior characterized, and a simplified computer model prepared which runs on desk-top minicomputers. This simplified model allows the investigation of the effects of the seven most significant variables in each of four waste areas: Liquid Waste Storage, Liquid Waste Solidification, General Process Trash Handling, and Hulls Handling. 8 references, 1 figure, 12 tables

  13. Biosorption behaviors of uranium (VI) from aqueous solution by sunflower straw and insights of binding mechanism

    International Nuclear Information System (INIS)

    Lian Ai; Xuegang Luo; Xiaoyan Lin; Sizhao Zhang


    Uranium (VI)-containing water has been recognized as a potential longer-term radiological health hazard. In this work, the sorptive potential of sunflower straw for U (VI) from aqueous solution was investigated in detail, including the effect of initial solution pH, adsorbent dosage, temperature, contact time and initial U (VI) concentration. A dose of 2.0 g L -1 of sunflower straw in an initial U (VI) concentration of 20 mg L -1 with an initial pH of 5.0 and a contact time of 10 h resulted in the maximum U (VI) uptake (about 6.96 mg g -1 ) at 298 K. The isotherm adsorption data was modeled best by the nonlinear Langmuir-Freundlich equation. The equilibrium sorption capacity of sunflower straw was observed to be approximately seven times higher than that of coconut-shell activated carbon as 251.52 and 32.37 mg g -1 under optimal conditions, respectively. The positive enthalpy and negative free energy suggested the endothermic and spontaneous nature of sorption, respectively. The kinetic data conformed successfully to the pseudo-second-order equation. Furthermore, energy dispersive X-ray, fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy demonstrated that U (VI) adsorption onto sunflower straw was predominantly controlled by ion exchange as well as complexation mechanism. The study revealed that sunflower straw could be exploited for uranium remediation of aqueous streams as a promising adsorbent. (author)

  14. Two-stage DNA compaction induced by silver ions suggests a cooperative binding mechanism (United States)

    Jiang, Wen-Yan; Ran, Shi-Yong


    The interaction between silver ions and DNA plays an important role in the therapeutic use of silver ions and in related technologies such as DNA sensors. However, the underlying mechanism has not been fully understood. In this study, the dynamics of Ag+-DNA interaction at a single-molecule level was studied using magnetic tweezers. AgNO3 solutions with concentrations ranging from 1 μM to 20 μM led to a 1.4-1.8 μm decrease in length of a single λ-DNA molecule, indicating that Ag+ has a strong binding with DNA, causing the DNA conformational change. The compaction process comprises one linear declining stage and another sigmoid-shaped stage, which can be attributed to the interaction mechanism. Considering the cooperative effect, the sigmoid trend was well explained using a phenomenological model. By contrast, addition of silver nanoparticle solution induced no detectable transition of DNA. The dependence of the interaction on ionic strength and DNA concentration was examined via morphology characterization and particle size distribution measurement. The size of the Ag+-DNA complex decreased with an increase in Ag+ ionic strength ranging from 1 μM to 1 mM. Morphology characterization confirmed that silver ions induced DNA to adopt a compacted globular conformation. At a fixed [AgNO3]:[DNA base pairs] ratio, increasing DNA concentration led to increased sizes of the complexes. Intermolecular interaction is believed to affect the Ag+-DNA complex formation to a large extent.

  15. Studies on binding mechanism between carotenoids from sea buckthorn and thermally treated α-lactalbumin (United States)

    Dumitraşcu, Loredana; Ursache, Florentina Mihaela; Stănciuc, Nicoleta; Aprodu, Iuliana


    Sea buckthorn is a natural food ingredient rich in bioactive compounds such as carotenoids, tocopherols, sterols, flavonoids, lipids, vitamins, tannins and minerals. Herein, fluorescence and UV-vis techniques were used to study the interaction of heat treated α-lactalbumin (α-LA) with carotenoids from sea buckthorn berries extract (CSB) and β-carotene. Further atomic level details on the interaction between α-LA and β-carotene were obtained by means of molecular modelling techniques. The quenching rate constants, binding constants, and number of binding sites were calculated in the presence of CSB. The emission spectral studies revealed that, CSB have the ability to bind α-LA and form a ground state complex via static quenching process. Maximum degree of quenching was reached at 100 °C, where β-carotene and CSB quenched the Trp fluorescence of α-LA by 56% and 47%, respectively. In order to reveal the interaction between CSB and α-LA, the thermodynamic parameters were determined from the van't Hoff plot based on the temperature dependence of the binding constant. In agreement with the in silico observations, the thermodynamic parameters enabled us to consider that the association between α-LA and β-carotene is a spontaneous process driven by enthalpy, dominated mainly by the van der Waals interaction, but hydrophobic interactions might also be considered. The interaction between CSB and α-LA was further confirmed by UV-vis absorption spectra, where a blue shift of position was noticed at higher temperature suggesting the complex formation. The results provided here supply a better understanding of the binding of CSB to α-LA, which can be further exploited in designing new healthy food applications.

  17. A model proposal concerning balance scorecard application integrated with resource consumption accounting in enterprise performance management

    Directory of Open Access Journals (Sweden)



    Full Text Available The present study intended to investigate the “Balance Scorecard (BSC model integrated with Resource Consumption Accounting (RCA” which helps to evaluate the enterprise as matrix structure in its all parts. It aims to measure how much tangible and intangible values (assets of enterprises contribute to the enterprises. In other words, it measures how effectively, actively, and efficiently these values (assets are used. In short, it aims to measure sustainable competency of enterprises. As expressing the effect of tangible and intangible values (assets of the enterprise on the performance in mathematical and statistical methods is insufficient, it is targeted that RCA Method integrated with BSC model is based on matrix structure and control models. The effects of all complex factors in the enterprise on the performance (productivity and efficiency estimated algorithmically with cause and effect diagram. The contributions of matrix structures for reaching the management functional targets of the enterprises that operate in market competitive environment increasing day to day, is discussed. So in the context of modern management theories, as a contribution to BSC approach which is in the foreground in today’s administrative science of enterprises in matrix organizational structures, multidimensional performance evaluation model -RCA integrated with BSC Model proposal- is presented as strategic planning and strategic evaluation instrument.

  19. Some considerations concerning the challenge of incorporating social variables into epidemiological models of infectious disease transmission. (United States)

    Barnett, Tony; Fournié, Guillaume; Gupta, Sunetra; Seeley, Janet


    Incorporation of 'social' variables into epidemiological models remains a challenge. Too much detail and models cease to be useful; too little and the very notion of infection - a highly social process in human populations - may be considered with little reference to the social. The French sociologist Émile Durkheim proposed that the scientific study of society required identification and study of 'social currents'. Such 'currents' are what we might today describe as 'emergent properties', specifiable variables appertaining to individuals and groups, which represent the perspectives of social actors as they experience the environment in which they live their lives. Here we review the ways in which one particular emergent property, hope, relevant to a range of epidemiological situations, might be used in epidemiological modelling of infectious diseases in human populations. We also indicate how such an approach might be extended to include a range of other potential emergent properties to represent complex social and economic processes bearing on infectious disease transmission.

  1. The importance of modelling in European decisions concerning energy and environment

    International Nuclear Information System (INIS)

    Rossetti di Valdalbero, D.


    Under pressure as much from the economic crisis as from a desire to improve governance, political decision makers seek to evaluate economic and social impacts of their choices. Quantification of trend projections and alternative scenarios - developed with the aid of economic and energy models - provide a base on which to make these choices. Attempts to put figures on and to clarify contrasting options provoke animated debates, both about the quantitative tools used (a scientific question) and on their use (a political question). This article aims to show the importance of the modellers in providing answers to these questions, by analysing the process of European policy decisions on energy and the environment over the period 1995-2005.

  2. Parametric sensitivity of a CFD model concerning the hydrodynamics of trickle-bed reactor (TBR

    Directory of Open Access Journals (Sweden)

    Janecki Daniel


    Full Text Available The aim of the present study was to investigate the sensitivity of a multiphase Eulerian CFD model with respect to relations defining drag forces between phases. The mean relative error as well as standard deviation of experimental and computed values of pressure gradient and average liquid holdup were used as validation criteria of the model. Comparative basis for simulations was our own data-base obtained in experiments carried out in a TBR operating at a co-current downward gas and liquid flow. Estimated errors showed that the classical equations of Attou et al. (1999 defining the friction factors Fjk approximate experimental values of hydrodynamic parameters with the best agreement. Taking this into account one can recommend to apply chosen equations in the momentum balances of TBR.

  3. Considerations Concerning Matrix Diagram Transformations Associated with Mathematical Model Study of a Three-phase Transformer

    Directory of Open Access Journals (Sweden)

    Mihaela Poienar


    Full Text Available The clock hour figure mathematical model of a threephase transformer can be expressed, in the most plain form, through a 3X3 square matrix, called code matrix. The lines position reflect the modification in the high voltage windings terminal and the columns position reflect the modification in the low voltage winding terminal. The main changes on the transformer winding terminal are: the circular permutation of connection between windings; terminal supply reversal; reverse direction for the phase winding wrapping; reversal the beginning with the end for a phase winding; the connection conversion from N in Z between phase winding or inverse. The analytical form of these changes actually affect the configuration of the mathematical model expressed through a transformations diagram proposed and analyzed in two ways: bipolar version and unipolar version (fanwise. In the end of the paper are presented about the practical exploitation of the transformations diagram.

    Full Text Available Compliant materials are used in applications of robotics for final elements of robotic systems. Contact pressure between a spherical indenter and a linear viscoelastic halfspace is modeled for a cosine normal load. The Maxwell viscoelastic halfspace is described by relaxation function and creep function. For the working frequency domain, the material does not present obvious relaxation. Only for very low frequencies, the pressure variation presents a maximum during approaching delayed with respect to maximum force

  6. Numerical examinations of simplified spondylodesis models concerning energy absorption in magnetic resonance imaging

    Directory of Open Access Journals (Sweden)

    Hadert Nicole


    Full Text Available Metallic implants in magnetic resonance imaging (MRI are a potential safety risk since the energy absorption may increase temperature of the surrounding tissue. The temperature rise is highly dependent on implant size. Numerical examinations can be used to calculate the energy absorption in terms of the specific absorption rate (SAR induced by MRI on orthopaedic implants. This research presents the impact of titanium osteosynthesis spine implants, called spondylodesis, deduced by numerical examinations of energy absorption in simplified spondylodesis models placed in 1.5 T and 3.0 T MRI body coils. The implants are modelled along with a spine model consisting of vertebrae and disci intervertebrales thus extending previous investigations [1], [2]. Increased SAR values are observed at the ends of long implants, while at the center SAR is significantly lower. Sufficiently short implants show increased SAR along the complete length of the implant. A careful data analysis reveals that the particular anatomy, i.e. vertebrae and disci intervertebrales, has a significant effect on SAR. On top of SAR profile due to the implant length, considerable SAR variations at small scale are observed, e.g. SAR values at vertebra are higher than at disc positions.

  7. Some open questions concerning the neutral-shielding model of a fuelling pellet

    International Nuclear Information System (INIS)

    Chang, C.T.


    To obtain a better understanding of the implications and assumptions of the idealized neutral shielding model of Parks and Turnbull, the model is reformulated in a self consistent way. Due to the uncertainty of the actual ablation process occuring at the pellet surface, alternative boundary conditions are proposed. Their effect on the pellet ablation rate and the state of the ablated flow are examined by numerical analyses. The results show that the ablation rate is not sensitively affected but the ablatant state is markedly influenced by the boundary condition at the pellet surface. In particular, an increase of the energy flux received at the pellet surface by a factor of four hardly affect the ablation rate but changes the temperature and the density of the ablatant at the pellet surface by three orders of magnitude. Based on these obtained results, it is concluded that the idealized ablation model is adequate when pellet injection is used to fuel a plasma but requires modification when it is used to probe plasma properties and discharge conditions.

  8. Concerning the modelling of systems in terms of Quantum Electrodynamics: the special case of 'Cold Fusion'

    International Nuclear Information System (INIS)

    Abyaneh, Morteza; Fleischmann, Martin; Del Giudice, Emilio; Vitiello, Giuseppe


    A question we are asked repeatedly is: 'what are the causes of the opposition to your belief in the reality of 'Cold Fusion?'. This question is normally asked in the context of the statement that Quantum Mechanics shows that this phenomenon is impossible (a view that we share). Our answer is always based on the statement 'but what about the modelling of such systems in terms of QED?' which is always met by the insistence that Quantum Mechanics shows that Cold Fusion is impossible. We conclude that scientists do not understand QED or, if they have some understanding of this subject, then this must be subject to some major misconceptions. This pointless dialogue (perhaps more correctly described as two monologues conducted in parallel) and the insistence on the primacy of Quantum Mechanics in the modelling of systems in the Natural Sciences is unfortunate because it obscures the outcome of the investigations in the more normal fields of the Natural Sciences (more normal than Cold Fusion). A brief outline of the work which has led to the formulation of the concept of coherence will therefore be given under the aegis of the revolutions in our understanding of the Natural Sciences which has taken place since the latter part of the 19. Century. The main illustration of the way we can demonstrate the applicability of these concepts will be based on the study of nucleation and phase growth. The development of micro-electrode substrates allows us to study the statistics of the formation of the first nucleus; it will be shown that these statistics are strictly in line with concepts developed from QED coherence. We conclude that QED coherence is not just a concept to be confined to sub-atomic physics, cosmology etc. but that it pervades the modelling of the whole of the Natural Sciences including that of 'Cold Fusion'. Some of the major steps which have taken place in the development of this subject area will be illustrated

    Yi-Man Teng


    Full Text Available The study investigates consumers’ intent to patron green restaurants by application of the Value-Attitude-Behavior model. The present study examines the interrelationships among consumers’ values, attitudes, and environmental concerns, and explores how they relate to their intentions to visit green restaurants in Taiwan. Data were gathered by face-to-face surveys, conducted by trained interviewers in a variety of locations, including at train stations, supermarkets, department stores, shopping malls, and adult education classes to obtain data from a representative demographic profile. The findings of this study suggest that the personal values and general attitudes positively affect consumers’ intentions to visit a green restaurant. Additionally, the results found personal values and environmental concern have significant influence on the attitude toward green restaurants. Managerial implications and future directions of these findings were also discussed.

  11. Regulation of Ocean Iron Fertilization (OIF): a Model for Balancing Research, Environmental and Policy Concerns (United States)

    Leinen, M.; Lamotte, R.


    The potential of enhancing carbon sequestration by the biosphere for climate mitigation often raises questions of offsetting effects. These questions become more important as the scale of the enhancement increases. Ocean iron fertilization is accompanied by additional questions related to use of the ocean commons. The London Convention (LC) and London Protocol (LP), international treaties adopted in 1972 and 1996 respectively, were designed to prevent use of the ocean for disposal of toxic, harmful and radioactive pollutants. Recently the LC/LP has been called upon to decide whether climate mitigation activities, such as subseafloor injection of CO2 and OIF, are legal under the framework and, if so, how they should be regulated. The broad consultation with the science community by the LC/LP in developing their perspective, and the involvement of the NGO community in these deliberations, provides a model for the process that the international policy community can use to develop science-based regulatory guidelines for carbon mitigation projects involving the commons. And the substance of that emerging regulatory framework -- built on a national-level permitting process informed by internationally agreed guidelines and standards -- may also serve as a model for the oversight of other emerging technologies that take place in the global commons.

  12. Perfectionism, weight and shape concerns, and low self-esteem: Testing a model to predict bulimic symptoms. (United States)

    La Mela, Carmelo; Maglietta, Marzio; Caini, Saverio; Casu, Giuliano P; Lucarelli, Stefano; Mori, Sara; Ruggiero, Giovanni Maria


    Previous studies have tested multivariate models of bulimia pathology development, documenting that a confluence of perfectionism, body dissatisfaction, and low self-esteem is predictive of disordered eating. However, attempts to replicate these results have yielded controversial findings. The objective of the present study was to test an interactive model of perfectionism, weight and shape concerns, and self-esteem in a sample of patients affected by Eating Disorder (ED). One-hundred-sixty-seven ED patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), and they completed the Eating Disorder Examination Questionnaire (EDE-Q), the Rosenberg Self-Esteem Scale (RSES), and the Multidimensional Perfectionism Scale (MPS-F). Several mediation analysis models were fit to test whether causal effects of concern over weight and shape on the frequency of bulimic episodes were mediated by perfectionism and moderated by low levels of self-esteem. Contrary to our hypotheses, we found no evidence that the causal relationship investigated was mediated by any of the dimensions of perfectionism. As a secondary finding, the dimensions of perfectionism, perceived criticism and parental expectations, were significantly correlated with the presence of bulimic symptoms. The validity of the interactive model remains controversial, and may be limited by an inadequate conceptualization of the perfectionism construct.

  13. Exploring the binding sites and binding mechanism for hydrotrope encapsulated griseofulvin drug on γ-tubulin protein.

    Directory of Open Access Journals (Sweden)

    Shubhadip Das

    Full Text Available The protein γ-tubulin plays an important role in centrosomal clustering and this makes it an attractive therapeutic target for treating cancers. Griseofulvin, an antifungal drug, has recently been used to inhibit proliferation of various types of cancer cells. It can also affect the microtubule dynamics by targeting the γ-tubulin protein. So far, the binding pockets of γ-tubulin protein are not properly identified and the exact mechanism by which the drug binds to it is an area of intense speculation and research. The aim of the present study is to investigate the binding mechanism and binding affinity of griseofulvin on γ-tubulin protein using classical molecular dynamics simulations. Since the drug griseofulvin is sparingly soluble in water, here we also present a promising approach for formulating and achieving delivery of hydrophobic griseofulvin drug via hydrotrope sodium cumene sulfonate (SCS cluster. We observe that the binding pockets of γ-tubulin protein are mainly formed by the H8, H9 helices and S7, S8, S14 strands and the hydrophobic interactions between the drug and γ-tubulin protein drive the binding process. The release of the drug griseofulvin from the SCS cluster is confirmed by the coordination number analysis. We also find hydrotrope-induced alteration of the binding sites of γ-tubulin protein and the weakening of the drug-protein interactions.

  16. Flawed Assumptions, Models and Decision Making: Misconceptions Concerning Human Elements in Complex System

    International Nuclear Information System (INIS)



    The history of high consequence accidents is rich with events wherein the actions, or inaction, of humans was critical to the sequence of events preceding the accident. Moreover, it has been reported that human error may contribute to 80% of accidents, if not more (dougherty and Fragola, 1988). Within the safety community, this reality is widely recognized and there is a substantially greater awareness of the human contribution to system safety today than has ever existed in the past. Despite these facts, and some measurable reduction in accident rates, when accidents do occur, there is a common lament. No matter how hard we try, we continue to have accidents. Accompanying this lament, there is often bewilderment expressed in statements such as, ''There's no explanation for why he/she did what they did''. It is believed that these statements are a symptom of inadequacies in how they think about humans and their role within technological systems. In particular, while there has never been a greater awareness of human factors, conceptual models of human involvement in engineered systems are often incomplete and in some cases, inaccurate

  17. [Transparency as a prerequisite of innovation in health services research: deficits in the reporting of model projects concerning managed care]. (United States)

    Wiethege, J; Ommen, O; Ernstmann, N; Pfaff, H


    Currently, elements of managed care are being implemented in the German health-care system. The legal basis for these innovations are § 140, § 73, § 137, and §§ 63 et seq. of the German Social Code - Part 5 (SGB V). For the model projects according to §§ 63 et seq. of the German Social Code a scientific evaluation and publication of the evaluation results is mandatory. The present study examines the status of evaluation of German model projects. The present study has a mixed method design: A mail and telephone survey with the German Federal Social Insurance Authority, the health insurance funds, and the regional Associations of Statutory Health Insurance Physicians has been conducted. Furthermore, an internet research on "Medpilot" and "Google" has been accomplished to search for model projects and their evaluation reports. 34 model projects met the inclusion criteria. 13 of these projects had been terminated up to 30/9/2008. 6 of them have published an evaluation report. 4 model projects have published substantial documents. One model project in progress has published a meaningful interim report. 12 model projects failed to give information concerning the evaluator or the duration of the model projects. The results show a significant deficit in the mandatory reporting of the evaluation of model projects in Germany. There is a need for action for the legislator and the health insurance funds in terms of promoting the evaluation and the publication of the results. The institutions evaluating the model projects should obligate themselves to publish the evaluation results. The publication is an essential precondition for the development of managed care structures in the health-care system and in the development of scientific evaluation methods. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Towards understanding the E. coli PNP binding mechanism and FRET absence between E. coli PNP and formycin A. (United States)

    Prokopowicz, Małgorzata; Greń, Bartosz; Cieśla, Joanna; Kierdaszuk, Borys


    The aim of this study is threefold: (1) augmentation of the knowledge of the E. coli PNP binding mechanism; (2) explanation of the previously observed 'lack of FRET' phenomenon and (3) an introduction of the correction (modified method) for FRET efficiency calculation in the PNP-FA complexes. We present fluorescence studies of the two E. coli PNP mutants (F159Y and F159A) with formycin A (FA), that indicate that the aromatic amino acid is indispensable in the nucleotide binding, additional hydroxyl group at position 159 probably enhances the strength of binding and that the amino acids pair 159-160 has a great impact on the spectroscopic properties of the enzyme. The experiments were carried out in hepes and phosphate buffers, at pH7 and 8.3. Two methods, a conventional and a modified one, that utilizes the dissociation constant, for calculations of the energy transfer efficiency (E) and the acceptor-to-donor distance (r) between FA and the Tyr (energy donor) were employed. Total difference spectra were calculated for emission spectra (λ ex 280nm, 295nm, 305nm and 313nm) for all studied systems. Time-resolved techniques allowed to conclude the existence of a specific structure formed by amino acids at positions 159 and 160. The results showed an unexpected pattern change of FRET in the mutants, when compared to the wild type enzyme and a probable presence of a structure created between 159 and 160 residue, that might influence the binding efficiency. Additionally, we confirmed the indispensable role of the modification of the FRET efficiency (E) calculation on the fraction of enzyme saturation in PNP-FA systems. Copyright © 2017 Elsevier B.V.

  19. Bridgman's concern

    International Nuclear Information System (INIS)

    Graham, R.A.


    In 1956 P.W. Bridgman published a letter to the editor in the Journal of Applied Physics reporting results of electrical resistance measurements on iron under static high pressure. The work was undertaken to verify the existence of a polymorphic phase transition at 130 kbar (13 GPa) reported in the same journal and year by the Los Alamos authors, Bancroft, Peterson and Minshall for high pressure, shock-compression loading. In his letter, Bridgman reported that he failed to find any evidence for the transition. Further, he raised some fundamental concerns as to the state of knowledge of shock-compression processes in solids. Later it was determined that Bridgman's static pressure scale was in error, and the shock observations became the basis for calibration of pressure values in static high pressure apparatuses. In spite of the error in pressure scales, Bridgman's concerns on descriptions of shock-compression processes were perceptive and have provided the basis for subsequent fundamental studies of shock-compressed solids. The present paper, written in response to receipt of the 1993 American Physical Society Shock-Compression Science Award, provides a brief contemporary assessment of those shock-compression issues which were the basis of Bridgman's 1956 concerns

  1. Revealing vilazodone's binding mechanism underlying its partial agonism to the 5-HT1A receptor in the treatment of major depressive disorder. (United States)

    Zheng, Guoxun; Xue, Weiwei; Yang, Fengyuan; Zhang, Yang; Chen, Yuzong; Yao, Xiaojun; Zhu, Feng


    It has been estimated that major depressive disorder (MDD) will become the second largest global burden among all diseases by 2030. Various types of drugs, including selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and serotonin receptor partial agonist/reuptake inhibitors (SPARIs), have been approved and become the primary or first-line medications prescribed for MDD. SPARI was expected to demonstrate more enhanced drug efficacy and a rapid onset of action as compared to SSRI and SNRI. As one of the most famous SPARIs, vilazodone was approved by the FDA for the treatment of MDD. Because of the great clinical importance of vilazodone, its binding mechanism underlying its partial agonism to the 5-HT 1A receptor (5-HT 1A R) could provide valuable information to SPARIs' drug-like properties. However, this mechanism has not been reported to date; consequently, the rational design of new efficacious SPARI-based MDD drugs is severely hampered. To explore the molecular mechanism of vilazodone, an integrated computational strategy was adopted in this study to reveal its binding mechanism and prospective structural feature at the agonist binding site of 5-HT 1A R. As a result, 22 residues of this receptor were identified as hotspots, consistently favoring the binding of vilazodone and its analogues, and a common binding mechanism underlying their partial agonism to 5-HT 1A R was, therefore, discovered. Moreover, three main interaction features between vilazodone and 5-HT 1A R have been revealed and schematically summarized. In summary, this newly identified binding mechanism will provide valuable information for medicinal chemists working in the field of rational design of novel SPARIs for MDD treatment.

  2. Environmental Concerns (United States)

    Alma, Peter


    This series of A-level social biology topic books responds to the changing demands of social biology syllabuses, with each text dealing with a particular area of interest. Although the series is primarily intended for students of A-level social biology, the books will appeal to students studying a wide range of biological subjects at A-level. Environmental Concerns covers topics common to several A-level human and social biology syllabuses. It is particularly relevant to the human ecology and conservation options. The text focuses on the social and economic implications of current ecological issues as well as the basic biological concepts involved. It deals with the causes, effects and prevention of atmospheric and water pollution as well as with the disruption of ecosystems by changes in land use. The conflict of interests between conservation and exploitation is discussed, along with management techniques including the controversial method of culling to maintain diversity. The moral and aesthetic aspects of conservation and management are emphasised throughout, in addition to the scientific background of these techniques.

  3. Location of power stations and measures for local people model analysis concerning location negotiation with local fishery association

    Wakatani, Yoshifumi; Yamanaka, Yoshiro (Central Research Inst. of electric Power Industry, Tokyo (Japan))


    The recent negotiation of enterprisers and local people concerning the location of power stations tends to extend for long periods because of diversified arguing points and the information exchange of high density, and also to be complicated by the interrelation with other points. It is a large problem to seek the policy of such negotiation for enterprisers to respond to local people. In this study, as the first step, the policy and action appeared in location negotiations and the development of the negotiations were analyzed on the cases of location, and two kinds of the model analysis were carried out, taking fishery compensation negotiation as the object among them. The knowledge was obtained about what response to local fishery associations is effective to promote the location. The classification of location negotiation and the factors affecting the development of negotiation were investigated. It was shown to be effective to divide the process of location negotiation into five stages of advancement. The model analysis was carried out according to game theory and by gaming simulation method. The results are reported.

  4. Emissions of volatile organic compounds during the ship-loading of petroleum products: Dispersion modelling and environmental concerns. (United States)

    Milazzo, Maria Francesca; Ancione, Giuseppa; Lisi, Roberto


    Emissions due to ship-loading of hydrocarbons are currently not addressed neither by the Directive on the integrated pollution prevention or by other environmental regulations. The scope of this study is to point towards the environmental and safety concerns associated with such emissions, even if proper attention has not been given to this issue until now. In order to achieve this goal, the modelling of the emission volatile organic compounds (VOC), due to ship-load operations at refineries has been made by means of the definition of a simulation procedure which includes a proper treatment of the hours of calm. Afterwards, a quantitative analysis of VOC dispersion for an Italian case-study is presented with the primary aims: (i) to develop and verify the validity of the approach for the modelling of the emission sources and of the diffusion of these contaminants into the atmosphere by a proper treatment of the hours of calm and (ii) to identify their contribution to the total VOC emitted in a typical refinery. The calculated iso-concentration contours have also been drawn on a map and allowed the identification of critical areas for people protecting by the adoption of abatement solutions.

  6. Results of a modeling workshop concerning economic and environmental trends and concomitant resource management issues in the Mobile Bay area (United States)

    Hamilton, David B.; Andrews, Austin K.; Auble, Gregor T.; Ellison, Richard A.; Johnson, Richard A.; Roelle, James E.; Staley, Michael J.


    During the past decade, the southern regions of the U.S. have experienced rapid change which is expected to continue into the foreseeable future. Growth in population, industry, and resource development has been attributed to a variety of advantages such as an abundant and inexpensive labor force, a mild climate, and the availability of energy, water, land, and other natural resources. While this growth has many benefits for the region, it also creates the potential for increased air, water, and solid waste pollution, and modification of natural habitats. A workshop was convened to consider the Mobile Bay area as a site-specific case of growth and its environmental consequences in the southern region. The objectives of the modeling workshop were to: (1) identify major factors of economic development as they relate to growth in the area over the immediate and longer term; (2) identify major environmental and resource management issues associated with this expected growth; and (3) identify and characterize the complex interrelationships among economic and environmental factors. This report summarizes the activities and results of a modeling workshop concerning economic growth and concomitant resource management issues in the Mobile Bay area. The workshop was organized around construction of a simulation model representing the relationships between a series of actions and indicators identified by participants. The workshop model had five major components. An Industry Submodel generated scenarios of growth in several industrial and transportation sectors. A Human Population/Economy Submodel calculated human population and economic variables in response to employment opportunities. A Land Use/Air Quality Submodel tabulated changes in land use, shoreline use, and air quality. A Water Submodel calculated indicators of water quality and quantity for fresh surface water, ground water, and Mobile Bay based on discharge information provided by the Industry and Human

    communities which were conceptualized as being adapted to frequent storms. This behavior was generated by the set of assumptions about linkages and functional relationships used to construct the model. Areas of uncertainty included methods for extrapolating 96-hr LC50 so results to exposures of varying lengths and concentrations; recovery rates of benthic communities; responses to various depths and rates of burial; fate and effects of the plume in relationship to stratification layers; and long-term and sub-lethal effects of slightly elevated concentrations of discharged materials. Evaluation of the assumptions of the Soft Bottom Submodel suggest that the assumptions used may have been relatively liberal estimates of resiliency of these communities. Discussion of "closed" water bodies such as bays and estuaries indicated several reasons to expect different and more complex fate and effects behavior in these areas. These factors included different species and communities (such as aquatic macrophytes and oyster beds), more complex circulation and stratification patterns, and potentially more active resuspension processes. Much of the possible difference in behavior in these areas centers around the extent to which they are “closed” or in the relative residence times of water and sediments in these areas as they determine the long-term dispersion of discharged material. Despite the complexity and variability of these areas, a large body of knowledge (such as that concerning fate and physical effects of dredge spoil) that could be effectively employed in analysis of potential fate and physical effects in enclosed areas was identified.

  9. A Two-pronged Binding Mechanism of IgG to the Neonatal Fc Receptor Controls Complex Stability and IgG Serum Half-life

    DEFF Research Database (Denmark)

    Jensen, Pernille Foged; Schoch, Angela; Larraillet, Vincent


    The success of recombinant monoclonal immunoglobulins (IgG) is rooted in their ability to target distinct antigens with high affinity combined with an extraordinarily long serum half-life, typically around 3 weeks. The pharmacokinetics of IgGs is intimately linked to the recycling mechanism...... half-life of ∼8 days. Here we dissect the molecular origins of excessive FcRn binding in therapeutic IgGs using a combination of hydrogen/deuterium exchange mass spectrometry and FcRn affinity chromatography. We provide experimental evidence for a two-pronged IgG-FcRn binding mechanism involving direct...

  10. Parental concern about vaccine safety in Canadian children partially immunized at age 2: a multivariable model including system level factors. (United States)

    MacDonald, Shannon E; Schopflocher, Donald P; Vaudry, Wendy


    Children who begin but do not fully complete the recommended series of childhood vaccines by 2 y of age are a much larger group than those who receive no vaccines. While parents who refuse all vaccines typically express concern about vaccine safety, it is critical to determine what influences parents of 'partially' immunized children. This case-control study examined whether parental concern about vaccine safety was responsible for partial immunization, and whether other personal or system-level factors played an important role. A random sample of parents of partially and completely immunized 2 y old children were selected from a Canadian regional immunization registry and completed a postal survey assessing various personal and system-level factors. Unadjusted odds ratios (OR) and adjusted ORs (aOR) were calculated with logistic regression. While vaccine safety concern was associated with partial immunization (OR 7.338, 95% CI 4.138-13.012), other variables were more strongly associated and reduced the strength of the relationship between concern and partial immunization in multivariable analysis (aOR 2.829, 95% CI 1.151-6.957). Other important factors included perceived disease susceptibility and severity (aOR 4.629, 95% CI 2.017-10.625), residential mobility (aOR 3.908, 95% CI 2.075-7.358), daycare use (aOR 0.310, 95% CI 0.144-0.671), number of needles administered at each visit (aOR 7.734, 95% CI 2.598-23.025) and access to a regular physician (aOR 0.219, 95% CI 0.057-0.846). While concern about vaccine safety may be addressed through educational strategies, this study suggests that additional program and policy-level strategies may positively impact immunization uptake.

  11. Why do we buy organic? Integrating knowledge, attitudes and concerns in a simultaneous equation model for Spanish consumers


    Gracia Royo, Azucena; Magistris, Tiziana de; Barreiro Hurlé, Jesús


    The behavior of the consumer for organic products has been largely explored in the academic literature, based both on actual and intended purchases. In Mediterranean Europe (mainly Italy, Spain and Greece) studies have shown that attitudes towards organic food, importance attached to different organic food attributes (human health, safety, etc.) and consumers’ concerns towards the environment are the most important factors that explain consumers’ organic food purchase decisions...

The D/C mosaic neurotoxin is the most toxic of the botulinum neurotoxins (BoNT) characterized to date. Here, we determined the crystal structure of the receptor binding domain of BoNT from strain OFD05 in complex with 3'-sialyllactose at a resolution of 3.0 A. In the structure, an electron density derived from the 3'-sialyllactose was confirmed at the cleft in the C-terminal subdomain. Alanine site-directed mutagenesis showed the significant contribution of the residues surrounding the cleft to ganglioside recognition. In addition, a loop adjoining the cleft also plays an important role in ganglioside recognition. In contrast, little effect was observed when the residues located around the surface previously identified as the protein receptor binding site in other BoNTs were substituted. The results of cell binding analysis of the mutants were significantly correlated with the ganglioside binding properties. Based on these observations, a cell binding mechanism of BoNT from strain OFD05 is proposed, which involves cooperative contribution of two ganglioside binding sites.

  13. Interaction of the protein transduction domain of HIV-1 TAT with heparan sulfate: binding mechanism and thermodynamic parameters. (United States)

    Ziegler, André; Seelig, Joachim


    The positively charged protein transduction domain of the HIV-1 TAT protein (TAT-PTD; residues 47-57 of TAT) rapidly translocates across the plasma membrane of living cells. This property is exploited for the delivery of proteins, drugs, and genes into cells. The mechanism of this translocation is, however, not yet understood. Recent theories for translocation suggest binding of the protein transduction domain (PTD) to extracellular glycosaminoglycans as a possible mechanism. We have studied the binding equilibrium between TAT-PTD and three different glycosaminoglycans with high sensitivity isothermal titration calorimetry and provide the first quantitative thermodynamic description. The polysulfonated macromolecules were found to exhibit multiple identical binding sites for TAT-PTD with only small differences between the three species as far as the thermodynamic parameters are concerned. Heparan sulfate (HS, molecular weight, 14.2 +/- 2 kDa) has 6.3 +/- 1.0 independent binding sites for TAT-PTD which are characterized by a binding constant K0 = (6.0 +/- 0.6) x 10(5) M(-1) and a reaction enthalpy deltaHpep0 = -4.6 +/- 1.0 kcal/mol at 28 degrees C. The binding affinity, deltaGpep0, is determined to equal extent by enthalpic and entropic contributions. The HS-TAT-PTD complex formation entails a positive heat capacity change of deltaCp0 = +135 cal/mol peptide, which is characteristic of a charge neutralization reaction. This is in contrast to hydrophobic binding reactions which display a large negative heat capacity change. The stoichiometry of 6-7 TAT-PTD molecules per HS corresponds to an electric charge neutralization. Light scattering data demonstrate a maximum scattering intensity at this stoichiometric ratio, the intensity of which depends on the order of mixing of the two components. The data suggest cross-linking and/or aggregation of HS-TAT-PTD complexes. Two other glycosaminoglycans, namely heparin and chondroitin sulfate B, were also studied with isothermal

  14. Maladaptive Five Factor Model personality traits associated with Borderline Personality Disorder indirectly affect susceptibility to suicide ideation through increased anxiety sensitivity cognitive concerns. (United States)

    Tucker, Raymond P; Lengel, Greg J; Smith, Caitlin E; Capron, Dan W; Mullins-Sweatt, Stephanie N; Wingate, LaRicka R


    The current study investigated the relationship between maladaptive Five-Factor Model (FFM) personality traits, anxiety sensitivity cognitive concerns, and suicide ideation in a sample of 131 undergraduate students who were selected based on their scores on a screening questionnaire regarding Borderline Personality Disorder (BPD) symptoms. Those who endorsed elevated BPD symptoms in a pre-screen analyses completed at the beginning of each semester were oversampled in comparison to those with low or moderate symptoms. Indirect effect (mediation) results indicated that the maladaptive personality traits of anxious/uncertainty, dysregulated anger, self-disturbance, behavioral dysregulation, dissociative tendencies, distrust, manipulativeness, oppositional, and rashness had indirect effects on suicide ideation through anxiety sensitivity cognitive concerns. All of these personality traits correlated to suicide ideation as well. The maladaptive personality traits of despondence, affective dysregulation, and fragility were positive correlates of suicide ideation and predicted suicide ideation when all traits were entered in one linear regression model, but were not indirectly related through anxiety sensitivity cognitive concerns. The implication for targeting anxiety sensitivity cognitive concerns in evidence-based practices for reducing suicide risk in those with BPD is discussed. Copyright © 2016 Elsevier Ireland Ltd.

  17. Docking based 3d-QSAR studies applied at the BRAF inhibitors to understand the binding mechanism

    International Nuclear Information System (INIS)

    Mahmood, U.; Haq, Z.U.


    BRAF is a great therapeutic target in a wide variety of human cancers. It is the member of Ras Activating Factor (RAF) family of serine/throenine kinase. The mutated form of the BRAF has diverted all the attention towards itself because of increase severity and elevated kinase activity. The RAF signal transduction cascade is a conserved protein pathway that is involved in cell cycle progression and apoptosis. The ERK regulates phosphorylation of different proteins either in cytosol or in nucleus but disorders in ERK signaling pathway cause mutation in BRAF. This cascade in these cells may provide selection of mutated BRAF in which valine is substituted with glutamatic acid at position 600. This mutation occurs in activation loop. A number of inhibitors reported to target different members of RAF, some of them have potential to target the BRAF as well. Major reason for failure of previously reported inhibitors was due to the highly conserved sequence and confirmation of catalytic cleft which is always a center of consideration for binding of inhibitors to suppress the kinase activity. This is the first attempt to study and understand the BARF inhibitors - protein interactions in detail by utilizing 3D-QSAR and molecular docking techniques. Most reliable techniques of 3D QSAR i.e Comparative Molecular Field Analysis (CoMFA) and Comparative Molecular Similarity Indices Analysis (CoMSIA) were applied for three different data sets. The data sets selected for better evaluation of BRAF inhibitors belongs to 2, 6-Disubstituted Pyrazine, Pyridoimidazolones and its derivatives. Our models would offer help to better understand the structure-activity relationships that exist for these classes of compounds and also facilitate the design of novel inhibitors with good chemical diversity.

  19. Whittling Down the Wait Time: Exploring Models to Minimize the Delay from Initial Concern to Diagnosis and Treatment of Autism Spectrum Disorder. (United States)

    Gordon-Lipkin, Eliza; Foster, Jessica; Peacock, Georgina


    The process from initial concerns to diagnosis of autism spectrum disorder (ASD) can be a long and complicated process. The traditional model for evaluation and diagnosis of ASD often consists of long wait-lists and evaluations that result in a 2-year difference between the earliest signs of ASD and mean age of diagnosis. Multiple factors contribute to this diagnostic bottleneck, including time-consuming evaluations, cost of care, lack of providers, and lack of comfort of primary care providers to diagnose autism. This article explores innovative clinical models that have been implemented to address this as well as future directions and opportunities. Copyright © 2016 Elsevier Inc. All rights reserved.

  20. Monetary Variables in Macmod. A note concerning the introduction of monetary variables in the Tanzanian macro economic model: Macmod


    Granberg, Per


    This paper discusses the relationship between money supply and production in Tanzania, wit special reference to Macmod, the macroeconomic model for Tanzania. The relationship between money supply and production is seen as being neither direct nor simple in nature: the paper argues that the money supply does not impact production directly, but via inflation. Other things being equal, one may consequently expect money supply to influence inflation, and inflation to affect production.

  1. Application of chemometric methods for assessment and modelling of microbiological quality data concerning coastal bathing water in Greece

    Agelos Papaioannou


    Full Text Available Background. Worldwide, the aim of managing water is to safeguard human health whilst maintaining sustainable aquatic and associated terrestrial, ecosystems. Because human enteric viruses are the most likely pathogens responsible for waterborne diseases from recreational water use, but detection methods are complex and costly for routine monitoring, it is of great interest to determine the quality of coastal bathing water with a minimum cost and maximum safety. Design and methods. This study handles the assessment and modelling of the microbiological quality data of 2149 seawater bathing areas in Greece over 10-year period (1997-2006 by chemometric methods. Results. Cluster analysis results indicated that the studied bathing beaches are classified in accordance with the seasonality in three groups. Factor analysis was applied to investigate possible determining factors in the groups resulted from the cluster analysis, and also two new parameters were created in each group; VF1 includes E. coli, faecal coliforms and total coliforms and VF2 includes faecal streptococci/enterococci. By applying the cluster analysis in each seasonal group, three new groups of coasts were generated, group A (ultraclean, group B (clean and group C (contaminated. Conclusions. The above analysis is confirmed by the application of discriminant analysis, and proves that chemometric methods are useful tools for assessment and modeling microbiological quality data of coastal bathing water on a large scale, and thus could attribute to effective and economical monitoring of the quality of coastal bathing water in a country with a big number of bathing coasts, like Greece.

  2. A Non-Linear Digital Computer Model Requiring Short Computation Time for Studies Concerning the Hydrodynamics of the BWR

    Energy Technology Data Exchange (ETDEWEB)

    Reisch, F; Vayssier, G


    This non-linear model serves as one of the blocks in a series of codes to study the transient behaviour of BWR or PWR type reactors. This program is intended to be the hydrodynamic part of the BWR core representation or the hydrodynamic part of the PWR heat exchanger secondary side representation. The equations have been prepared for the CSMP digital simulation language. By using the most suitable integration routine available, the ratio of simulation time to real time is about one on an IBM 360/75 digital computer. Use of the slightly different language DSL/40 on an IBM 7044 computer takes about four times longer. The code has been tested against the Eindhoven loop with satisfactory agreement.

  3. Experience in biosphere modelling and definition of exposed groups. Concerns on consideration of the long-term

    International Nuclear Information System (INIS)

    Pinedo, P.


    The long life of high level waste and their 'possible' releases, from the repository, in the far future during wide time frames, introduce difficulties on the ability of forecasting actual doses. Similar difficulties were found when trying to establish or recommend protection criteria for the environment and human health. The stochastic nature of the whole problem, from the causes that initiate radionuclides releases to the nature of the environmental conditions where impact is evaluated, made more complex the treatment of the radionuclide transport models and the analysis of radiological impact. The application of radiological protection principles to this management option, was also seen as different from other present-day practices. All this gave rise to the diversification of the research lines towards new areas that allow for the analysis of radionuclide transport, dose calculations and, criteria, in this new situation. The approach for the biosphere system based on the 'reference' concept, in essence the same idea as the one for the 'Reference man' concept, was promoted internationally, first within the BIOMOVS II Project and, afterwards, in the BIOMASS IAEA Programme. In parallel to the participation in these Projects and based on their conclusions, CIEMAT has been developing for ENRESA a methodology, which has to be updated and completed with recent developments from BIOMASS-Theme1. Notably, for the Justification and Identification step, the Description of Critical Groups and the use of the Data protocol. An application of this methodology was performed and published in 1998 and, its results and conclusions are summarised in the paper. Also, the paper includes main conclusions from the biosphere modelling applied in the last ENRESA2000 Spanish PA exercise and, difficulties found in the consistency between the scenario generation procedure, the treatment of the interface and the source term and, the use of the reference biosphere concept.

  4. Selection, Identification, and Binding Mechanism Studies of an ssDNA Aptamer Targeted to Different Stages of E. coli O157:H7. (United States)

    Zou, Ying; Duan, Nuo; Wu, Shijia; Shen, Mofei; Wang, Zhouping


    Enterohemorrhagic Escherichia coli O157:H7 ( E. coli O157:H7) is known as an important food-borne pathogen related to public health. In this study, aptamers which could bind to different stages of E. coli O157:H7 (adjustment phase, log phase, and stationary phase) with high affinity and specificity were obtained by the whole cell-SELEX method through 14 selection rounds including three counter-selection rounds. Altogether, 32 sequences were obtained, and nine families were classified to select the optimal aptamer. To analyze affinity and specificity by flow cytometer, an ssDNA aptamer named Apt-5 was picked out as the optimal aptamer that recognizes different stages of E. coli O157:H7 specifically with the K d value of 9.04 ± 2.80 nM. In addition, in order to study the binding mechanism, target bacteria were treated by proteinase K and trypsin, indicating that the specific binding site is not protein on the cell membrane. Furthermore, when we treated E. coli O157:H7 with EDTA, the result showed that the binding site might be lipopolysaccharide (LPS) on the outer membrane of E. coli O157:H7.

  5. Using model fish to study the biological mechanisms of cooperative behaviour: A future for translational research concerning social anxiety disorders? (United States)

    Soares, Marta C; Cardoso, Sónia C; Carvalho, Tamires Dos Santos; Maximino, Caio


    Human societies demand of its composing members the development of a wide array of social tools and strategies. A notable example is human outstanding ability to cooperate with others, in all its complex forms, depicting the reality of a highly demanding social framework in which humans need to be integrated as to attain physical and mental benefits. Considering the importance of social engagement, it's not entirely unexpected that most psychiatric disorders involve some disruption of normal social behaviour, ranging from an abnormal absence to a significant increase of social functioning. It is however surprising that knowledge on these social anxiety disorders still remains so limited. Here we review the literature focusing on the social and cooperative toolbox of 3 fish model species (cleaner fishes, guppies and zebrafish) which are amenable systems to test for social disorders. We build on current knowledge based on ethological information, arising from studies on cooperative behaviour in cleanerfishes and guppies, while profiting from the advantages of the intense use of zebrafish, to create novel paradigms aiming at the major socio-cognitive modules/dimensions in fish species. This focus may enable the discovery of putative conserved endpoints which are relevant for research into social disorders. We suggest that cross-species, cross-domain, functional and genetic approaches could provide a wider array of information on the neurobiological bases of social and cooperative behaviour, crucial to understanding the neural bases of social disorders and key to finding novel avenues towards treatment.

    Directory of Open Access Journals (Sweden)

    Yoshifumi Kido

    Full Text Available The objective of this study was to clarify consumer providers (CPs subjective experiences as members of a psychiatric multidisciplinary outreach team that provided services to individuals with a mental illness living in the community.A qualitative descriptive study was conducted through semi-structured interviews. Participants were clients hired as CPs in the Japanese Outreach Model Project from September 2011 until March 2014. Of the seventeen CPs, nine participated in this study. We looked at the CPs' subjective experiences of fulfillment and difficulty.In the process of providing services, CPs experienced both achievements and concerns. They had a sense of achievement by caring for their clients and they experienced that they themselves were recovering. They were also concerned about having inadequate knowledge and skills to provide psychiatric services to their clients. Further, there were concerns about their dual role on the multidisciplinary team and being support staff while they were still using mental health services themselves.The results show that the activities of CPs included fulfillment, recovery, and dilemmas. Clarifications will likely contribute to an increase in understanding and cooperation between CPs and other professionals with whom they work. Further studies are needed to investigate policies related to mental health consumers who are also providers of mental health services.

    Aerial vehicles have become indispensable. There are in this field UAV (Unconventional Aerial vehicle) and transportation airplanes and other aerospace vehicles for spatial tourism. Today, the research and development activity in aerospace industry is focused to obtain a good and efficient design for airplanes, to solve the problem of high pollution and to reduce the noise. For these goals are necessary to realize light and resistant components. The aerospace industry products are, generally, very complex concerning geometric shapes and the costs are high, usually. Due to the progress in this field (products obtained using FDM) was possible to reduce the number of used tools, welding belts, and, of course, to eliminate a lot of machine tools. In addition, the complex shapes are easier product using this high technology, the cost is more attractive and the time is lower. This paper allows to present a few aspects about FDM technology and the obtained structures using it, as follows: computer geometric modeling (different designing softs) to design and redesign complex structures using 3D printing, for this kind of vehicles; finite element analysis to identify what is the influence of design for different structures; testing the structures.

    Handler, Marc Zachary; Goldberg, David J


    Men are interested in reducing signs of aging, while maintaining a masculine appearance. A chief concern among men is maintenance of scalp hair. Men are also concerned with reducing under eye bags and dark circles. The concern of feminization is of significant importance. Neuromodulators remain the most common cosmetic procedure performed in men. Men often prefer a reduction in facial rhytids, as opposed to elimination of the lines. Softening facial lines in men is meant to maintain an appearance of wisdom, without appearing fragile. Men also wish to maintain a taut jawline and a slim waist and reduce breast tissue.

  15. Medical Students Raising Concerns. (United States)

    Druce, Maralyn R; Hickey, Andrea; Warrens, Anthony N; Westwood, Olwyn M R


    After a number of high-profile incidents and national reports, it has become clear that all health professionals and all medical students must be able to raise concerns about a colleague's behavior if this behavior puts patients, colleagues, or themselves at risk.Detailed evidence from medical students about their confidence to raise concerns is limited, together with examples of barriers, which impair their ability to do so. We describe a questionnaire survey of medical students in a single-center, examining self-reported confidence about raising concerns in a number of possible scenarios. Thematic analysis was applied to comments about barriers identified.Although 80% of respondents felt confident to report a patient safety issue, students were less confident around issues of probity, attitude, and conduct. This needs to be addressed to create clear mechanisms to raise concerns, as well as support for students during the process.

    Research suggests that fairness perceptions matter to people who are asked to evaluate the acceptability of risks or risk management. Two separate national random surveys (n = 305 and n = 529) addressed Americans' concerns about and acceptance of nanotechnology risk management in the context of the degree to which they view scientists and risk managers as fair. The first survey investigated general views about scientists across four proposed dimensions of fairness (distributional, procedural, interpersonal, and informational). The results show that respondents who believe that the outcomes of scientific research tend to result in unequal benefits (distributional fairness) and that the procedures meant to protect the public from scientific research are biased (procedural fairness) were more concerned about nanotechnology. Believing scientists would treat them with respect (interpersonal fairness) and ensure access to information (informational fairness) were not significant predictors of concern. The second study also looked at these four dimensions of fairness but focused on perceptions of risk managers working for government, universities, and major companies. In addition to concern, it also examined acceptance of nanotechnology risk management. Study 2 results were similar to those of study 1 for concern; however, only perceived informational fairness consistently predicted acceptance of nanotechnology risk management. Overall, the study points to the value of considering fairness perceptions in the study of public perceptions of nanotechnology. © 2011 Society for Risk Analysis.

  2. Empathic concern drives costly altruism (United States)

    FeldmanHall, Oriel; Dalgleish, Tim; Evans, Davy; Mobbs, Dean


    Why do we self-sacrifice to help others in distress? Two competing theories have emerged, one suggesting that prosocial behavior is primarily motivated by feelings of empathic other-oriented concern, the other that we help mainly because we are egoistically focused on reducing our own discomfort. Here we explore the relationship between costly altruism and these two sub-processes of empathy, specifically drawing on the caregiving model to test the theory that trait empathic concern (e.g. general tendency to have sympathy for another) and trait personal distress (e.g. predisposition to experiencing aversive arousal states) may differentially drive altruistic behavior. We find that trait empathic concern – and not trait personal distress – motivates costly altruism, and this relationship is supported by activity in the ventral tegmental area, caudate and subgenual anterior cingulate, key regions for promoting social attachment and caregiving. Together, this data helps identify the behavioral and neural mechanisms motivating costly altruism, while demonstrating that individual differences in empathic concern-related brain responses can predict real prosocial choice.

  4. Markets for Collective Concerns

    DEFF Research Database (Denmark)

    Frankel, Christian; Ossandón, José; Pallesen, Trine

    Despite the recent fall-out of finance, confidence in the market does not seem to be diminishing, but, on the contrary, market mechanisms are becoming key instruments to deal with core contemporary collective concerns, including global warming, education, environmental pollution, supply of energy......, quality of education, poverty and health care (Mirowski 2013). Recent research within STS has started to focus on such kind of arrangements and in this presentation we will critically engage with this literature. Our main results are twofold. On the one hand, we recognize there are important conceptual...... tools already available - such as 'matters of public concern' (Marres 2007) and 'hybrid forums' (Callon et al. 2001; Callon 2009)- that help in framing the particularity of these arrangements. On the other hand, previous STS-market research notions developed mostly in the field of finance studies cannot...

  5. Concern for older parts

    International Nuclear Information System (INIS)

    Titus, E.; Spink, T.; Cookson, B.; Tenera, L.P.


    For the last half decade, regulatory expectations of the procurement process for nuclear commercial-grade safety-related materials have increase. The changes have been driven by concern for fraudulent or misrepresented parts and the loss of original equipment manufacturers. The industry responded to these concerns by developing improved procurement programs that changed how parts were specified and received and provided for verification of attributes that were critical to the successful performance of safety functions(s). Like its counterparts, Duquesne Light Company (DLCo), Beaver Valley power station began applying these enhanced requirements to procurements initiated after January 1, 1990, in response to the Nuclear Management and Resources Council initiative on dedication. Procurements prior to this data were not subject to the new requirements

  6. The Question Concerning Thinking

    DEFF Research Database (Denmark)

    Riis, Søren


    Martin Heidegger's thought-provoking essay "The Question Concerning Technology" (1977a) placed technology at the heart of philosophy. Heidegger tried to show that the essence of technology provokes humans to think about the world in a very dangerous way. Yet if we follow Heidegger's analysis...... of technology, what role does that ascribe to philosophy? To be able to understand the programmatic scope of Heidegger's question ‘concerning' technology, we need to see it as inseparable from his famous thesis about the end of philosophy (1977c) and what he considers to be the ideal kind of thinking. However......, by doing so, we will in the end realize two important things. First, that Heidegger's declaration of the end of philosophy in fact also means the end of anything we can meaningfully call thinking. Second, that Heidegger's own thinking is completely different from his own ideal of thinking. Our question...

    psychology or Kübler-Ross’ theory about death stages. The complex concerns might be explained using Martin Heidegger’s phenomenological thinking. We aimed to illuminate dying patients´ existential concerns about the impending death through a descriptive analysis of semi-structured interviews with 17 cancer...... patients in Danish hospices. The main findings demonstrated how the patients faced the forthcoming death without being anxious of death but sorrowful about leaving life. Furthermore, patients expressed that they avoided thinking about death. However, some had reconstructed specific and positive ideas about...... afterlife and made accurate decisions for practical aspects of their death. The patients wished to focus on positive aspects in their daily life at hospice. It hereby seems important to have ongoing reflections and to include different theoretical perspectives when providing existential support to dying...

  8. Career Concerns in Teams


    Auriol, Emmanuelle; Friebel, Guido; Pechlivanos, Lambros


    We investigate how changes in the commitment power of a principal affect cooperation among agents who work in a team. When the principal and her agents are symmetrically uncertain about the agents' innate abilities, workers have career concerns. Then, unless the principal can commit herself to long-term wage contracts, an implicit sabotage incentive emerges. Agents become reluctant to help their teammates. Anticipating this risk, and in order to induce the desired level of cooperation, the pr...

    Full Text Available The issue of probabilities, uncertainties and risks has concerned society since ancient times. By probability we can see the possible realization of an act or event under certain conditions. Uncertainty is caused by emotional status of the decision maker due to more subjective factors or to the knowledge to achieve an objective. Risk is a combination of the two elements characterized by a possible description of probabilities under insecurity uncertainty conditions.

  11. Financial equilibrium with career concerns

    Directory of Open Access Journals (Sweden)

    Amil Dasgupta


    Full Text Available What are the equilibrium features of a financial market where a sizeable proportion of traders face reputational concerns? This question is central to our understanding of financial markets, which are increasingly dominated by institutional investors. We construct a model of delegated portfolio management that captures key features of the US mutual fund industry and embed it in an asset pricing framework. We thus provide a formal model of financial equilibrium with career concerned agents. Fund managers differ in their ability to understand market fundamentals, and in every period investors choose a fund. In equilibrium, the presence of career concerns induces uninformed fund managers to churn, i.e., to engage in trading even when they face a negative expected return. Churners act as noise traders and enhance the level of trading volume. The equilibrium relationship between fund return and net fund flows displays a skewed shape that is consistent with stylized facts. The robustness of our core results is probed from several angles.

  12. A twin study of body dysmorphic concerns. (United States)

    Monzani, B; Rijsdijk, F; Anson, M; Iervolino, A C; Cherkas, L; Spector, T; Mataix-Cols, D


    Dysmorphic concern refers to an excessive preoccupation with a perceived or slight defect in physical appearance. It lies on a continuum of severity from no or minimal concerns to severe concerns over one's appearance. The present study examined the heritability of dysmorphic concerns in a large sample of twins. Twins from the St Thomas UK twin registry completed a valid and reliable self-report measure of dysmorphic concerns, which also includes questions about perceived body odour and malfunction. Twin modelling methods (female twins only, n=3544) were employed to decompose the variance in the liability to dysmorphic concerns into additive genetic, shared and non-shared environmental factors. Model-fitting analyses showed that genetic factors accounted for approximately 44% [95% confidence intervals (CI) 36-50%] of the variance in dysmorphic concerns, with non-shared environmental factors and measurement error accounting for the remaining variance (56%; 95% CI 50-63%). Shared environmental factors were negligible. The results remained unchanged when excluding individuals reporting an objective medical condition/injury accounting for their concern in physical appearance. Over-concern with a perceived or slight defect in physical appearance is a heritable trait, with non-shared environmental factors also playing an important role in its causation. The results are relevant for various psychiatric disorders characterized by excessive concerns in body appearance, odour or function, including but not limited to body dysmorphic disorder.

    Institute of Scientific and Technical Information of China (English)



    In China, there is an old saying:food is the first necessity of humans. The main concern of the Chinese used to be the security of the food supply rather than the safety of the food itself. However,after a long time fighting food shortages,China became self-sufficient in food in 1995. At this time, the country began for the first time to regulate food safety. Yet China has still not established a legal systern efficient in ensuring this safety. Many problems are rooted in the administration regime and China's priority of economic development.

    International Nuclear Information System (INIS)

    Siddiqi, T.A.


    Increased concern about global climate change is leading to an examination of options for reducing the emissions of gases believed to be the principal contributors to the Greenhouse Effect. Carbon dioxide is believed to be the largest contributor to such an effect, and the use of fossil fuels is the largest source of carbon dioxide emissions. geothermal energy is likely to receive increased attention in the years ahead as a way to reduce emissions of CO 2 . Several countries in Asia and the Pacific already have active geothermal programs. The Philippines have the second-largest installed geothermal capacity in the world. Japan and New Zealand have used geothermal energy for several decades. The present and future contributions of geothermal energy to the overall energy supply and reductions in carbon dioxide emissions in Asia and the Pacific are discussed in this paper

    Magdalena Bobe


    Full Text Available The responsibility of organizations to the consumer has now become a permanent concern, the principles of ethics in their activities result in attracting new customers and thus in their remaining within competition. The present study aims to highlight the importance of producers’ accountability in ensuring the quality of foodstuffs obtained through sustainable methods of production and to correctly and completely inform the consumers. The research follows the quality analysis of a product with an “organic image” addressed to the market/consumers, by testing the physicochemical and microbiological characteristics in the laboratory of the National Research and Development Institute for Food Bio- Resources in Bucharest, as well as comparing the obtained results with the values stated in the producer’s specifications; the main purpose is checking the conformity and establishing the validity of the published nutritional information and the statements regarding the product’s quality made on the printed label.

  3. Identification of Ideal Multi-targeting Bioactive Compounds Against Mur Ligases of Enterobacter aerogenes and Its Binding Mechanism in Comparison with Chemical Inhibitors. (United States)

    Chakkyarath, Vijina; Natarajan, Jeyakumar


    Enterobacter aerogenes have been reported as important opportunistic and multi-resistant bacterial pathogens for humans during the last three decades in hospital wards. The emergence of drug-resistant E. aerogenes demands the need for developing new drugs. Peptidoglycan is an important component of the cell wall of bacteria and the peptidoglycan biochemical pathway is considered as the best source of antibacterial targets. Within this pathway, four Mur ligases MurC, MurD, MurE, and MurF are responsible for the successive additions of L-alanine and suitable targets for developing novel antibacterial drugs. As an inference from this fact, we modeled the three-dimensional structure of above Mur ligases using best template structures available in PDB and analyzed its common binding features. Structural refinement and energy minimization of the predicted Mur ligases models is also being done using molecular dynamics studies. The models of Mur ligases were further investigated for in silico docking studies using bioactive plant compounds from the literature. Interestingly, these results indicate that four plant compounds Isojuripidine, Atroviolacegenin, Porrigenin B, and Nummularogenin showing better docking results in terms of binding energy and number of hydrogen bonds. All these four compounds are spirostan-based compounds with differences in side chains and the amino acid such as ASN, LYS, THR, HIS, ARG (polar) and PHE, GLY, VAL, ALA, MET (non-polar) playing active role in binding site of all four Mur ligases. Overall, in the predicted model, the four plant compounds with its binding features could pave way to design novel multi-targeted antibacterial plant-based bioactive compounds specific to Mur ligases for the treatment of Enterobacter infections.

  4. Concerning ethical risk assessment

    International Nuclear Information System (INIS)

    Boeckle, F.


    After a fundamental consideration of the concept of responsibility and 'long-term responsibility' for late sequelae, the problems of an ehtical assessment of risks were illustrated: The concept of risk itself poses three problems - predicting the probability of occurrence, assessing the damage = subjective classification of the degree of damage, determining whether the advantages outweigh the risks. It is not possible to weigh the advantages and risks against each other without assessing the goals and the priorities which have been set. Here ethics is called for, because it concerns itself with the reasonableness of evaluative decisions. Its task is to enable us to become aware of and comprehend our system of values in all of its complexity in reference to real life. Ethics can only fulfill its task if it helps us to adopt an integral perspective, i.e. if it centers on the human being. 'One must assess all technical and economic innovations in terms of whether they are beneficial to the development of mankind on a long-term basis. They are only to be legitimized insofar as they prove themselves to be a means of liberating mankind and contributing to his sense of dignity and identity, as a means of bringing human beings together and encouraging them to care for one another, and as a means of protecting the natural basis of our existence.

  6. Addressing Thermal Model Run Time Concerns of the Wide Field Infrared Survey Telescope using Astrophysics Focused Telescope Assets (WFIRST-AFTA) (United States)

    Peabody, Hume; Guerrero, Sergio; Hawk, John; Rodriguez, Juan; McDonald, Carson; Jackson, Cliff


    The Wide Field Infrared Survey Telescope using Astrophysics Focused Telescope Assets (WFIRST-AFTA) utilizes an existing 2.4 m diameter Hubble sized telescope donated from elsewhere in the federal government for near-infrared sky surveys and Exoplanet searches to answer crucial questions about the universe and dark energy. The WFIRST design continues to increase in maturity, detail, and complexity with each design cycle leading to a Mission Concept Review and entrance to the Mission Formulation Phase. Each cycle has required a Structural-Thermal-Optical-Performance (STOP) analysis to ensure the design can meet the stringent pointing and stability requirements. As such, the models have also grown in size and complexity leading to increased model run time. This paper addresses efforts to reduce the run time while still maintaining sufficient accuracy for STOP analyses. A technique was developed to identify slews between observing orientations that were sufficiently different to warrant recalculation of the environmental fluxes to reduce the total number of radiation calculation points. The inclusion of a cryocooler fluid loop in the model also forced smaller time-steps than desired, which greatly increases the overall run time. The analysis of this fluid model required mitigation to drive the run time down by solving portions of the model at different time scales. Lastly, investigations were made into the impact of the removal of small radiation couplings on run time and accuracy. Use of these techniques allowed the models to produce meaningful results within reasonable run times to meet project schedule deadlines.

  7. Respect, trust, and the management of sickle cell disease pain in hospital: comparative analysis of concern-raising behaviors, preliminary model, and agenda for international collaborative research to inform practice (United States)

    Elander, James; Beach, Mary Catherine; Haywood, Carlton


    Background/objectives Qualitative interview studies suggest that adult patients’ experiences of hospital treatment for sickle cell disease (SCD) pain reflect an absence of respect by providers for patients, and an absence or breakdown of trust. Systematic comparisons between treatment settings could help identify contextual influences on respect and trust. Design Quantitative comparison of concern-raising behaviors (pain treatment outcomes indicating breakdowns of trust) among adult SCD patients in Baltimore, Maryland, USA, and London, UK, followed by analysis of potential explanations for differences, including socio-cultural and behavioral factors, with a preliminary model of the processes leading to concern-raising behaviors. Results Rates of concern-raising behaviors were significantly higher in Baltimore than London. The model identifies respect and trust as key factors which could be targeted in efforts to improve the quality of SCD pain management in hospital. Conclusion An agenda for international, interdisciplinary research to improve the treatment of SCD pain in hospital should include: comparative analyses between countries and treatment settings of factors that could influence respect and trust; research to test hypotheses derived from models about the roles of respect and trust in the treatment of pain; studies of the impact of healthcare structures and policy on patients’ experiences of care; research focusing on developmental and interpersonal processes related to respect and trust; applications of attribution and other social psychology theories; and development and evaluation of interventions to improve the hospital treatment of SCD pain by increasing respect and trust.

  8. A spatio-temporal simulation model of the response of solid tumours to radiotherapy in vivo: parametric validation concerning oxygen enhancement ratio and cell cycle duration

    International Nuclear Information System (INIS)

    Antipas, Vassilis P; Stamatakos, Georgios S; Uzunoglu, Nikolaos K; Dionysiou, Dimitra D; Dale, Roger G


    Advanced bio-simulation methods are expected to substantially improve radiotherapy treatment planning. To this end a novel spatio-temporal patient-specific simulation model of the in vivo response of malignant tumours to radiotherapy schemes has been recently developed by our group. This paper discusses recent improvements to the model: an optimized algorithm leading to conformal shrinkage of the tumour as a response to radiotherapy, the introduction of the oxygen enhancement ratio (OER), a realistic initial cell phase distribution and finally an advanced imaging-based algorithm simulating the neovascularization field. A parametric study of the influence of the cell cycle duration T c , OER, OER β for the beta LQ parameter on tumour growth, shrinkage and response to irradiation under two different fractionation schemes has been made. The model has been applied to two glioblastoma multiforme (GBM) cases, one with wild type (wt) and another one with mutated (mt) p53 gene. Furthermore, the model has been applied to a hypothetical GBM tumour with α and β values corresponding to those of generic radiosensitive tumours. According to the model predictions, a whole tumour with shorter T c tends to repopulate faster, as is to be expected. Furthermore, a higher OER value for the dormant cells leads to a more radioresistant whole tumour. A small variation of the OER β value does not seem to play a major role in the tumour response. Accelerated fractionation proved to be superior to the standard scheme for the whole range of the OER values considered. Finally, the tumour with mt p53 was shown to be more radioresistant compared to the tumour with wt p53. Although all simulation predictions agree at least qualitatively with the clinical experience and literature, a long-term clinical adaptation and quantitative validation procedure is in progress

    Gallice, Aurélie; Birkved, Morten; Kech, Sébastien

    obtained applying SewageLCI 1.0 model reveal that it’s possible to account for many of the variations in emission quantities of chemicals, caused by variations in the chemical fate properties and in the composition of national waste water treatment grids. The results indicate that the total emission...... treatment is emission to surface water recipients, other environmental compartments such as agricultural soil may receive considerable loads of chemicals emitted by the national specific waste water grids. The SewageLCI 1.0 presentation and case study reveal how broad inclusion of chemicals emitted......Lack of inventory data on chemical emissions often forces life cycle assessors to rely on crude emissions estimates (e.g. 100 % of the applied chemical mass is assumed emitted) or in the worst case to omit chemical emissions due to lack of emission data.

  10. Implications and concerns of deep-seated disposal of hydrocarbon exploration produced water using three-dimensional contaminant transport model in Bhit Area, Dadu District of Southern Pakistan. (United States)

    Ahmad, Zulfiqar; Akhter, Gulraiz; Ashraf, Arshad; Fryar, Alan


    A three-dimensional contaminant transport model has been developed to simulate and monitor the migration of disposal of hydrocarbon exploration produced water in Injection well at 2,100 m depth in the Upper Cretaceous Pab sandstone, Bhit area in Dadu district of Southern Pakistan. The regional stratigraphic and structural geological framework of the area, landform characteristics, meteorological parameters, and hydrogeological milieu have been used in the model to generate the initial simulation of steady-state flow condition in the underlying aquifer's layers. The geometry of the shallow and deep-seated characteristics of the geological formations was obtained from the drilling data, electrical resistivity sounding surveys, and geophysical well-logging information. The modeling process comprised of steady-state simulation and transient simulation of the prolific groundwater system of contamination transport after 1, 10, 30 years of injection. The contaminant transport was evaluated from the bottom of the injection well, and its short- and long-term effects were determined on aquifer system lying in varying hydrogeological and geological conditions.

  11. Some observations concerning blade-element-momentum (BEM) methods and vortex wake methods, including numerical experiments with a simple vortex model

    Energy Technology Data Exchange (ETDEWEB)

    Snel, H. [Netherlands Energy Research Foundation ECN, Renewable Energy, Wind Energy (Netherlands)


    Recently the Blade Element Momentum (BEM) method has been made more versatile. Inclusion of rotational effects on time averaged profile coefficients have improved its achievements for performance calculations in stalled flow. Time dependence as a result of turbulent inflow, pitching actions and yawed operation is now treated more correctly (although more improvement is needed) than before. It is of interest to note that adaptations in modelling of unsteady or periodic induction stem from qualitative and quantitative insights obtained from free vortex models. Free vortex methods and further into the future Navier Stokes (NS) calculations, together with wind tunnel and field experiments, can be very useful in enhancing the potential of BEM for aero-elastic response calculations. It must be kept in mind however that extreme caution must be used with free vortex methods, as will be discussed in the following chapters. A discussion of the shortcomings and the strength of BEM and of vortex wake models is given. Some ideas are presented on how BEM might be improved without too much loss of efficiency. (EG)

  14. Parents' concern about their children's weight. (United States)

    Lampard, Amy M; Byrne, Susan M; Zubrick, Stephen R; Davis, Elizabeth A


    Firstly, to investigate the degree of concern parents feel about their children's weight (parental concern). Secondly, to identify factors that influence this concern, and to test a model of parental concern using structural equation modeling. A total of 347 non-overweight, overweight, and obese children (aged 6-13; Mean = 9.5, SD = 1.8) and their parents. Children and their parents attended an assessment session during which they were weighed and measured. Parents were administered a structured interview, which included the Eating Disorder Examination, and completed the Pediatric Quality of Life Inventory (parent proxy), and the Children's Body Image Scale. Eighty-two percent of parents of overweight children, and 18% of parents of obese children reported little parental concern. Higher parental concern was associated with higher child Body Mass Index, less parental underestimation of child body size, and lower child health-related quality of life. Interventions targeting childhood obesity should aim to optimise parental concern by reducing parents' underestimation of child body size and increasing their awareness of the effects of overweight and obesity on children's health and quality of life.

  15. Maternal Concern for Child Undereating. (United States)

    Brown, Callie L; Pesch, Megan H; Perrin, Eliana M; Appugliese, Danielle P; Miller, Alison L; Rosenblum, Katherine; Lumeng, Julie C

    To describe features of maternal concern for her child undereating; examine maternal and child correlates of maternal concern for undereating; and determine whether maternal concern for undereating is associated with feeding practices. This was a cross-sectional analysis of an observational study with 286 mother-child dyads (mean child age, 71 months). Maternal concern for undereating was assessed using a semistructured interview. Mothers completed questionnaires to assess picky eating, food neophobia, and feeding practices. Feeding practices were further assessed using videotaped mealtime observations. Logistic regression was used to assess the association of maternal and child characteristics with maternal concern for undereating. Regression was used to assess the association of maternal concern for undereating with feeding practices, controlling for covariates. Over a third of mothers (36.5%) expressed concern that their child does not eat enough. Correlates of concern for undereating included child body mass index z-score (BMIz; odds ratio [OR] = 0.58; 95% confidence interval [CI], 0.43-0.77) and picky eating (OR = 2.41; 95% CI, 1.26-4.59). Maternal concern for undereating was associated with greater reported pressure to eat (relative risk [RR] = 1.97; 95% CI, 1.55-2.50), greater observed bribery (OR = 2.63; 95% CI, 1.50-4.60), and higher observed pressure (OR = 1.90; 95% CI, 1.08-3.36) during mealtimes. Mothers of children who are picky eaters and have a lower BMIz are more likely to be concerned that their children do not eat enough, and maternal concern for undereating is associated with pressuring and bribing children to eat. Pediatricians might address maternal concern for undereating by advising feeding practices that do not involve pressure and bribery, particularly among healthy weight children.

    Koch, Alexander; Morgenstern, Albrecht


    concerns arise. The effects of career concerns can both be 'good' (enhancing incentives for effort in developing ideas) and 'bad' (preventing voluntary coordination). Our model shows how a firm can take these conflicting forces into account through the design of its explicit incentive system and the way......A firm's innovation process requires employees to develop novel ideas and to coordinate with each other to turn the tacit knowledge embodying these ideas into better products and services. Such work outcomes provide signals about employees' abilities to the labor market, and therefore career...

  17. Women trafficking: causes, concerns, care! (United States)

    Khowaja, Shaneela Sadaruddin; Tharani, Ambreen Jawed; Agha, Ajmal; Karamaliani, Rozina Sherali


    Pakistan is both a country of origin and destination as far as women trafficking is concerned. Poverty, gender discrimination, lack of education, and ignorance about legal rights are some of the underlying causes. Available data suggest several areas of concern, like, for instance: direct health effects, maladaptive coping leading to the use of illicit drugs, and inaccessibility to healthcare facilities. Therefore, numerous interventions would be required at three levels: the prevention of trafficking, the protection of victims and the prosecution of the traffickers.

  19. Radioactive waste below regulatory concern

    International Nuclear Information System (INIS)

    Neuder, S.M.


    The U.S. Nuclear Regulatory Commission (NRC) published two notices in the Federal Register concerning radioactive waste below regulatory concern. The first, a Commission Policy Statement and Implementation Plan published August 29, 1986, concerns petition to exempt specific radioactive waste streams from the regulations. The second, an Advanced Notice of Proposed Rulemaking published Decemger 2, 1986, addresses the concept of generic rulemaking by the NRC on radioactive wastes that are below regulatory concern. Radioactive waste determined to be below regulatory concern would not be subject to regulatory control and would not need to go to a licensed low-level radioactive waste disposal site. The Policy Statement and Implementation Plan describe (1) the information a petitioner should file in support of a petition to exempt a specific waste stream, (2) the decision criteria the Commission intends to use for judging the petition, and (3) the internal administrative procedures to use be followed in order to permit the Commission to act upon the petition in an expedited manner

    Budoi, G.; Berca, M.; Borlan, Z.; Gavriluta, I.; Soare, M.; Danuso, F.; Bireescu, L.


    The 'Fertexpert' model allows undertaking researches concerning the variation of efficiency indexes for fertilizers usage in the case of many crops depending on the content of available soil nutrients (the values of soil agrochemical indexes - IA) and on the expected yield, R s , when fertilization are applied in optimal economic rates, DOE. The physical efficiency indexes calculated and researched are the following: the total physical yield increase, SFR (kg/ha), the specific average yield increase, SSp (kg/kg N, P 2 O 5 or K 2 O), the specific consumption of active substance (a.s.) from fertilizer, CSp (kg a.s./1 kg average yield increase). The economic efficiency indexes computed are: the total profit, in monetary units/ha, the specific profit, in monetary units/l monetary unit spent with fertilization, PSp, and in monetary units/kg a.s., PSpsa. The model also allows the study of DOE variation depending on R s and IA. Starting from the made calculations, there can be drown up specific graphics that can then be used in practice and for research purposes to. Refs. 6 (author)

  5. Clarification of the confusion concerning the crystal-field quantities vs the zero-field splitting quantities in magnetism studies: Part II-Survey of literature dealing with model studies of spin systems

    International Nuclear Information System (INIS)

    Rudowicz, C.


    For respective quantities, i.e., Hamiltonians, parameters, and energy level splittings, related to two physically distinct notions X and Y, various cases of confused terminology have been identified in literature. Referring to a quantity related actually to the notion Y using incorrectly the name of another well-defined notion X constitutes, what may be defined for short as, the type X=Y confusion. An ongoing survey of magnetism literature indicates that quantities related to zero-field splitting (ZFS) or equivalently fine structure (FS) are most often confused with those related to crystal-field (CF) or equivalently ligand field (LF). In this review the CF=ZFS confusion cases, i.e., labelling actual ZFS/FS quantities as purportedly 'CF/LF' ones, appearing in magnetism studies are surveyed and clarified. Part I covers the cases occurring in literature dealing with specific compounds. In this part model studies of spin systems are surveyed. The cases of terminology mixing up actual ZFS/FS quantities with purported CF/LF ones are identified and presented comprehensively in tabular form. To facilitate discussion, problems pertinent for the CF=ZFS confusion are categorized into several groups, including origin of the two notions, physical consequences, usage of specific numerical values, invoking real magnetic spin systems, and properties of spin S=1/2 systems. Physical implications of this confusion for interpretation of model results are also considered. Overall implications of incorrect terminology go beyond simple semantic issues and concern possible misinterpretation of data describing various physical properties of models studied. Such terminology contributes also to misleading keyword classifications of papers in journals and scientific databases. Other types of confusion identified in survey of magnetism literature will be discussed in separate reviews

    Energy Technology Data Exchange (ETDEWEB)



    For the purpose of reducing energy consumption and CO2 discharge in a cement plant in Indonesia, R and D was conducted on new clinker cooling system, high performance kiln combustion system, and technology for steady kiln operation and control, with the fiscal 1999 results reported. In the research on the optimum clinker cooling system, a new type clinker cooling system (CCS) was developed in which air beams are applied only to stationary grate rows, in an air beam type clinker cooling system where cooling air is fed to each block, with grate plates used as the air duct. This year, in an actual machine testing equipment (capacity 2,500 t/d), the whole heat recuperation area was modified for the CCS, with the operation started since February, 1999, aiming at the optimal clinker cooling effect and high heat recovery efficiency. The heat quantity for the entire system showed a decrease of 60 kcal/kg in the heat consumption rate through CCS modification, kiln burner adjustment, etc. So long as the demonstration plant is concerned, design of a new type burner and study/design for the kiln stabilization were nearly completed.

  7. Hypochondriacal Concerns: Management Through Understanding (United States)

    Holder-Perkins, Vicenzio; Wise, Thomas N.; Williams, Darren E.


    The medically unexplained complaint is often a symptom of hypochondriacal concerns. Patients with hypochondriasis may be managed with either naive realism or consideration of morbid categorization or via dimensional assessment of illness beliefs and behaviors. Naive realism will foster focus somatization and promote regression as well as lead to needless tests and treatments. Attention to categorical entities such a major depression or anxiety disorders will alert the clinician to comorbid psychiatric disorders that respond to traditional psychiatric treatments. Finally, by assessing the domains of illness behaviors such as disease conviction, beliefs in organic versus psychological causes, and denial, the clinician can document and then confront abnormal cognitive schema that revolve around somatic concerns that are a proxy for psychosocial difficulties.

  10. Weight, shape, and muscularity concerns in male and female adolescents: Predictors of change and influences on eating concern. (United States)

    Hoffmann, Svenja; Warschburger, Petra


    The purpose of this study was to examine the impact of age and weight status on adolescents' body dissatisfaction and its change over 20 months in a gender-comparing design. The influence of body image concern on eating concern was also investigated. In a prospective study, 675 male and female adolescents aged 12-16 were assessed using self-report questionnaires on weight, shape, muscularity, and eating concerns. Height and weight measurements were taken by trained personnel. Data were analyzed using structural equation modeling. Analyses of latent means revealed more pronounced weight/shape concern in females than males and more pronounced muscularity concern in males than females. Weight/shape concern increased in females over time, whereas muscularity concern remained stable in both genders. Baseline levels of weight/shape concern could be predicted by age and weight status in females and by weight status in males. The only predictor of change in weight/shape concern was weight status in males. Baseline levels of muscularity concern could be predicted by age in females and by weight status in males. Similar effects were found for changes in muscularity concern in both genders. Increases in weight/shape and muscularity concern were associated with more pronounced eating concern. The results confirm gender differences in distinctive facets of body image concern and its prediction. The relevance of increase in body image concern in adolescents is underlined by its association with eating concern in both genders. Further explanatory variables for change in body dissatisfaction should be examined in future studies. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:139-147). © 2016 Wiley Periodicals, Inc.

  13. Phytotoxins: environmental micropollutants of concern? (United States)

    Bucheli, Thomas D


    Natural toxins such as mycotoxins or phytotoxins (bioactive compounds from fungi and plants, respectively) have been widely studied in food and feed, where they are stated to out-compete synthetic chemicals in their overall human and animal toxicological risk. A similar perception and awareness is yet largely missing for environmental safety. This article attempts to raise concern in this regard, by providing (circumstantial) evidence that phytotoxins in particular can be emitted into the environment, where they may contribute to the complex mixture of organic micropollutants. Exposures can be orders-of-magnitude higher in anthropogenically managed/affected (agro-)ecosystems than in the pristine environment.

  14. Food biotechnology: benefits and concerns. (United States)

    Falk, Michael C; Chassy, Bruce M; Harlander, Susan K; Hoban, Thomas J; McGloughlin, Martina N; Akhlaghi, Amin R


    Recent advances in agricultural biotechnology have highlighted the need for experimental evidence and sound scientific judgment to assess the benefits and risks to society. Nutrition scientists and other animal biologists need a balanced understanding of the issues to participate in this assessment. To date most modifications to crop plants have benefited producers. Crops have been engineered to decrease pesticide and herbicide usage, protect against stressors, enhance yields and extend shelf life. Beyond the environmental benefits of decreased pesticide and herbicide application, consumers stand to benefit by development of food crops with increased nutritional value, medicinal properties, enhanced taste and esthetic appeal. There remains concern that these benefits come with a cost to the environment or increased risk to the consumer. Most U.S. consumers are not aware of the extent that genetically modified foods have entered the marketplace. Consumer awareness of biotechnology seems to have increased over the last decade, yet most consumers remain confused over the science. Concern over the impact on the safety of the food supply remains low in the United States, but is substantially elevated in Europe. Before a genetically engineered crop is introduced into commerce it must pass regulatory scrutiny by as many as four different federal regulatory bodies to ensure a safe food supply and minimize the risk to the environment. Key areas for more research are evaluation of the nutritional benefits of new crops, further investigation of the environmental impact, and development of better techniques to identify and track genetically engineered products.

    Full Text Available Nanotechnology deals with the construction of new materials, devices, and different technological systems with a wide range of potential applications at the atomic and molecular level. Nanomaterials have attracted great attention for numerous applications in chemical, biological, and industrial world because of their fascinating physicochemical properties. Nanomaterials and nanodevices are being produced intentionally, unintentionally, and manufactured or engineered by different methods and released into the environment without any safety test. Nantoxicity has become the subject of concern in nanoscience and nanotechnology because of the increasing toxic effects of nanomaterials on the living organisms. Nanomaterials can move freely as compared to the large-sized particles; therefore, they can be more toxic than bulky materials. This review article delineates the toxic effects of different types of nanomaterials on the living organisms through different sources, like water, air, contact with skin, and the methods of determinations of these toxic effects.

  17. [Several problems concerning population investment]. (United States)

    Liu, Z


    Population investment is a major topic in the studies of population and economic relations. In this particular area, numerous theoretical and practical problems are still in need of solution. Concerning the problem of population concept, there are three different approaches: (1) to determine the definition of population investment from the relationship between the population growth and the capital from national income used for investment, including investment in the newly increased population and investment in the entire population; (2) to explain population investment from the economic viewpoint that people are producers; and (3) to explain population investment from the expense needed to change a simple labor force to a skillful labor force. The expenses include educational costs, maintanance spending, wages needed to compensate workers in labor, costs for workers to master and learn modern scientific techniques to be used for production, and the costs of keeping a young labor force in the next generation.

  18. [Obesity in children. Current concerns]. (United States)

    Casado de Frías, Enrique


    In the last years there has been a growing interest in chilhood obesity in all developed countries. There is a great concern that is prevalence has raised 2-3 fold during the last 20 years. In the spanish chilhood population the obesity prevalence is estimated around 13%. Of note also, a number of other pathologies develop concomitantly with obesity during chilhood. These include type 2 diabetes, a range of respiratory problems, a metabolic syndrome, liver steatosis and seudotumor cerebri among others. Taking for granted that chilhood obesity in its roots is an exogenous disorder, preventive interventions should focus on modifying those ethiologies, improving the ways and nature of chilhood nutrition and its social and ludic behaviours.

  19. HEPA filter concerns - an overview

    Energy Technology Data Exchange (ETDEWEB)

    Leonard, J.F. [Department of Energy, Washington, DC (United States)


    The U.S. Department of Energy (DOE) recently initiated a complete review of the DOE High Efficiency Particulate Air (HEPA) Filter Program to identify areas for improvement. Although this process is currently ongoing, various issues and problems have already been identified for action that not only impacts the DOE HEPA filter program, but potentially the national and international air cleaning community as well. This paper briefly reviews a few of those concerns that may be of interest, and discusses actions initiated by the DOE to address the associated issues and problems. Issues discussed include: guidance standards, in-place testing, specifications, Test Facilities, portable units, vacuum cleaners, substitute aerosols, filter efficiencies, aging/shelf life/service life, fire suppression, handbook, Quality Products List (QPL), QA testing, and evaluations.

    Climate change is already causing, and is expected to continue to cause, a range of health impacts that vary across different population groups in the United States. The vulnerability of any given group is a function of its sensitivity to climate change related health risks, its exposure to those risks, and its capacity for responding to or coping with climate variability and change. Vulnerable groups of people, described here as populations of concern, include those with low income, some communities of color, immigrant groups (including those with limited English proficiency), Indigenous peoples, children and pregnant women, older adults, vulnerable occupational groups, persons with disabilities, and persons with preexisting or chronic medical conditions. Planners and public health officials, politicians and physicians, scientists and social service providers are tasked with understanding and responding to the health impacts of climate change. Collectively, their characterization of vulnerability should consider how populations of concern experience disproportionate, multiple, and complex risks to their health and well-being in response to climate change. Some groups face a number of stressors related to both climate and non-climate factors. For example, people living in impoverished urban or isolated rural areas, floodplains, coastlines, and other at-risk locations are more vulnerable not only to extreme weather and persistent climate change but also to social and economic stressors. Many of these stressors can occur simultaneously or consecutively. Over time, this “accumulation” of multiple, complex stressors is expected to become more evident1 as climate impacts interact with stressors associated with existing mental and physical health conditions and with other socioeconomic and demographic factors.

  1. Alternative energy and environmental concerns

    International Nuclear Information System (INIS)


    The New Brunswick Market Design Committee will address environmental concerns within the context of the new energy policy and market rules for the newly restructured electric power industry. The new rules that come with power restructuring will in some ways facilitate environmental protection but they can also complicate it. With open access markets, it will be possible to coordinate evolving energy frameworks with current environmental objectives. Restructuring provides an opportunity to create incentives and guidelines to operate in an environmentally sustainable manner, as suggested in the New Brunswick Energy Policy, White Paper which outlines green pricing, the development of a provincial Climate Change Action Plan, and promotion of alternative energy. The Market Design Committee examined the environmental concerns listed within the White Paper that pertain to the generation and transmission of electricity. These include the integration of energy and environmental policy. Other issues addressed in this report were trans-boundary and global air emissions, the development of a provincial climate change action plan, and a federal-provincial climate change framework agreement. New Brunswick will encourage the development of pilot studies that demonstrate the benefits of renewable and alternative technologies and that help promote the market to manufacture, sell and maintain renewable and alternative technologies in small-scale on-site power generation. This report also discussed the 4 key air pollutants for which specific treatment has been defined, including sulphur dioxide, nitrogen oxides, mercury and carbon dioxide. Recommendations for reducing these emissions include the use of renewable energy sources, the use of lower carbon fuels, increased efficiency of power transmission/generation/distribution systems, reducing power demand by the industrial sector, and promoting energy efficient building codes. 34 refs., 1 tab

  3. Food irradiation: benefits and concerns

    International Nuclear Information System (INIS)

    Thayer, D.W.


    The benefits and concerns about treating foods with ionizing radiation are reviewed. Radioactivity cannot be induced in foods by treatment with gamma rays from 137 Cs or 60 Co, X-ray sources of 5 MeV or lower energy, or electrons of 10 MeV or lower energy. The evidence supports the safety and efficacy of using ionizing radiation for insect disinfestation of grains; dried spices, vegetables and fruits; and fresh fruit. Species and dose dependent phytotoxic and vitamin changes may occur in some fruits at greater doses than currently approved by the U.S. Food and Drug Administration. Irradiation can inactivate protozoan or helminth parasites and significantly decrease the probability of viable food-borne bacterial pathogens in fish, poultry, and red meats. The titers of amino acids, fatty acids, and vitamins of chicken meat sterilized by thermal, electron-beam, or gamma radiation are presented. On the whole, the data support the safely and efficacy of the process

  5. Mobile phones and health concerns

    International Nuclear Information System (INIS)

    Vaikuntam, Shreenivas; Pushparaja


    As Mobile Cellular phone ownership grows throughout the developed as well as the developing world, concerns about the health risks due to radio frequency emissions from the mobile phone base stations and due to usage of mobile handsets are slowly growing. This article has a look at the concepts used in the mobile phone technology, the power outputs from base stations and mobile handsets, the quantities Specific Energy Absorption Rate (SAR) and power density as a means to assess the effects on biological tissue. The precautionary approach to manage the health risks from mobile phones by specifying exposure guidelines is explored. Having surveyed the relevant epidemiological surveys and finding them inconclusive, NRPB, United Kingdom's national regulatory body has issued exposure guidelines based on the potential of RF radiation to cause illness or injury through heating of body tissues. USA's Federal Communications Commission (FCC) limits are also listed for comparison. ICNIRP has issued two-tier guidelines, differentiating between occupational and public exposure. The public exposure limits are kept at one-fifth of the occupational exposure limits. The evidence till date, suggests that exposure to RF radiation below NRPB and ICNIRP limits do not cause adverse effects to the general population. However, the gaps in our knowledge warrant a precautionary approach. (author)

  6. Public concern for nuclear power

    International Nuclear Information System (INIS)

    Bibb, W.R.


    Three principles that the U.S. must follow in order to maintain its present way of life are stated: practice of energy conservation; substitution of the more plentiful fuels for the scarce; and development of synthetic fuels and unconventional energy sources. After describing the organizing of the energy agencies and reviewing the history of the nuclear power program in the U.S., the author then discusses the public's concern for nuclear energy which includes radioactive discharges, reactor safety, high-level wastes, and shipment of radioactive materials. He refers to the study by Dr. Norman C. Rasmussen released in 1974, which indicates that the likelihood of a person living in the general vicinity of a reactor being injured in any one year in a reactor accident is one chance in 150 million as compared to his chance of being injured in an automobile accident in that same year as one in 130. On a broader societal viewpoint, if there were 100 reactors operating in the U.S., one individual of the 15 million inhabitants living in the vicinity of these reactors might be killed and two individuals might be injured every 25 years as compared to 1.5 million injuries and 55,000 fatalities in 1974 due to automobile accidents. The author concludes that public acceptance of nuclear power will depend on whether these plants, after a reasonable maturing period, deliver the reliable, economic, and safe power that has been proclaimed

  7. Myths concerning alpine skiing injuries. (United States)

    Johnson, Robert J; Ettlinger, Carl F; Shealy, Jasper E


    There are many commonly discussed myths about ski safety that are propagated by industry, physicians, and skiers. Through a review of the literature concerning 12 such topics, this article demonstrates that the following are untrue: (1) Broken legs have been traded for blown-out knees. (2) If you know your DIN (a slang term for release indicator value), you can adjust your own bindings. (3) Toe and heel piece settings must be the same to function properly. (4) Formal ski instruction will make you safer. (5) Very short skis do not need release bindings. (6) Spending a lot of money on children's equipment is not worth the cost. (7) Children need plenty of room in ski boots for their growing feet. (8) If you think you are going to fall, just relax. (9) Exercise can prevent skiing injuries. (10) Lower release settings can reduce the risk of anterior cruciate ligament injury. (11) Buying new ski equipment is safer than renting. (12) Skiing is among the most dangerous of activities. It is important for the skiing public, physicians, and all those interested in improving skiing safety to verify the measures they advocate. The statements analyzed here are simply untrue and have the potential to cause harm if taken as fact by those exposed to these unsupported opinions.

    The analytical programme developed by the firm I.B.M. for ECAP electronic circuits, operated initially on the IBM 1620 computer with a certain limitation on the size of the network studied, but already equipped from the conversational angle (type-writer). The IBM 360 computers made it possible to increase the size of the network treated to 50 nodes and 200 branches, but the conversational aspect was suppressed in the ECAP 360 version. With a view to making use of the possibilities of hybrid computers, we have adapted this latter version to the EAI 8400 computer. Without diminishing it in any way, we have modified it so as to provide it with conversational characteristics by using the computers control panel; to give it still further flexibility we have made it possible to record curves during the calculation operation, and to obtain a division of the printed results. To obtain the curves, use was made of analog digital converters of the interface of the hybrid unit EAI 8900 of which the EAI 8400 computer represents the numerical section. The modifications made concern in particular the A.C. analysis and the transient analysis. They facilitate and complete the input of the data; they allow modifications to be made for the calculation of these analyses; they also improve the presentation of the results and facilitate their interpretation. They constitute finally the version ECASAC, i.e. the programme ECAP 360 made conversational by use of a type-writer, with automatic output of the curves. (author) [fr

  11. Zika virus: Current concerns in India

    Directory of Open Access Journals (Sweden)

    Sumit Bhardwaj


    Full Text Available With confirmation of Zika virus (ZIKV presence in India, screening of a large number of febrile illness samples yielded only four positive cases. In this review, we address the current concern with context to India. The possible reasons for low level of Zika prevalence in India have been discussed, by extracting some probable explanations from previous experience of chikungunya virus-vector model/studies. In the current context, it is hypothesized that Indian mosquito strains have lower susceptibility gradient/threshold for ZIKV. The very low positivity in the humans also indicates low levels of mosquito-human-mosquito transmission cycle. There is also a need to look for the existence of any such animal cycle/sylvatic involvement in India. The recently detected four cases in India show local transmission of ZIKV suggesting that ZIKV might have been present in India since long time. The earlier vector-virus relationship studies with chikungunya suggested that in due course of time, ZIKV might become a major public health concern in the future.

  12. Forms of concern: toward an intersubjective perspective. (United States)

    Tolmacz, Rami


    The growing interest in the issue of concern, which appeared relatively late in psychoanalytical literature, resulted in several distinctions. Winnicott distinguished between concern as an expression of guilt and concern as a manifestation of joy, Brenman Pick distinguished between real concern and spurious concern, and Bowlby distinguished between sensitive and compulsive caregiving. The basic concepts of Buber's dialogical philosophy and intersubjective approaches in psychoanalysis have created fertile ground for the study of concern, and enabled us to conceptualize these distinctions in a way that has heretofore been lacking in psychoanalytical thought.

  19. Moral considerations concerning income inequality

    Directory of Open Access Journals (Sweden)

    Jurjen P. de Vries


    Full Text Available The income inequality evident today has reached ethically unwarranted levels. In the Old and New Testament the Bible teaches us that disparity in wealth ought to meet the norms of justice and equity. Differences in income must be proportional to differences in the workers’performance and the responsibilities they assume. Employers and trade unions have the duty to ensure that these boundaries are respected. The government’s obligation is to take measures against the abuse of power monopolies, but it does not have to pursue income equality as such. Finally, where greed still rules society, Christians have the task to model a different life. In die hedendaagse samelewing kan aansienlike inkomsteverskille nie eties verantwoordword nie. In sowel die Ou as Nuwe Testament leer die Bybel ons dat verskille in inkomste aan die norm van regverdigheid en billikheid moet voldoen. Inkomsteverskille moet in ’n sinvolle verhouding tot die verskil in prestasie en verantwoordelikheid staan. Werkgewers en vakbonde moet in hierdie opsig die nodige grense in stand hou. Die owerheid kan maatreëls instel teen die wanpraktyke van magsmonopolieë, maar nie teen inkomste-ongelykhede as sulks nie. Wanneer hebsug die botoon in ’n samelewing voer, is dit die taak van Christene om’n eie lewenstyl te handhaaf. In de hedendaagse maatschappij zijn de inkomensverschillen groter dan ethisch verantwoord is. Het Oude en Nieuwe Testament van de Bijbel leren dat financiële verhoudingen moeten voldoen aan de normen van rechtvaardigheid en billijkheid. Inkomensverschillen moeten in redelijke verhouding staan tot het verschil in prestatie en verantwoordelijkheid. Werkgevers en vakorganisaties moeten hier de verantwoorde grenzen bewaken. De overheid neemt maatregelen tegen misbruik van machtsmonopolies ten eigen bate, maar voor haar is nivellering niet een doel op zich. En als in de maatschappij de hebzucht nog de boventoon voert, is het de taak van christenen hier een eigen

  20. Sexual concerns among kidney transplant recipients. (United States)

    Muehrer, Rebecca J; Lanuza, Dorothy M; Brown, Roger L; Djamali, Arjang


    Little is known about the specific sexual concerns of kidney transplant (KTx) recipients. The primary objectives of this study were to: (i) describe the importance of sexuality to KTx recipients; (ii) investigate the sexual concerns of KTx recipients; and (iii) examine the relationship between sexual concerns and quality of life (QOL). A secondary objective was to examine potential sexual concern differences by gender, pre-transplant dialysis status, and donor type. This study employed a cross-sectional, descriptive, correlational design. Sexual concerns were identified using the Sexual Concerns Questionnaire, which contains seven subscales. QOL was measured with the SF-8 and the QOL Uniscale. Nearly 73% of subjects rated sexuality as important. Subscales indicating highest area of sexual concerns were communication with healthcare providers about sexuality (Mean (M) = 2.70) and sexual pleasure concerns (M = 2.45). Higher concern ratings regarding health consequences of sexual activity, quality of sexual relationship, sexual pleasure, sexual functioning problems, and pessimistic beliefs about treatment were significantly, inversely related to QOL. Women had significantly higher scores on the Sexual Pleasure and Communication with Healthcare Providers subscales than men. This study reports the sexual concerns of KTx recipients' who are an average of four yr since surgery, and the relationship of these concerns to QOL. © 2014 John Wiley & Sons A/S.

  1. Occupational health concerns in the welding industry. (United States)

    Korczynski, R E


    The Workplace Safety and Health Branch initiated a proactive study in the welding industry in Manitoba. Eight welding companies participated in this study. Health concerns raised by welders were welders' flash, sore/red/teary eyes, headaches, nosebleeds, and a black mucous discharge from their nasal membrane. Most welders expressed concern regarding excessive smoke levels in the workplace and inadequate ventilation. Types of welding identified were MIG mild steel, MIG stainless steel, and TIG aluminum. Monitoring involved an assessment of noise levels, fume composition, and carbon monoxide and ozone concentrations. Metal analyses were according to National Institute for Occupational Safety and Health (NIOSH) Method 7300. Noise dosimeters used were the Quest model 100 and Micro 14 & 15. Carbon monoxide was monitored using the Gastech Model 4700 and ozone using the AID Portable Ozone Meter Model 560. In Manitoba, a hearing conservation program is required when the equivalent sound exposure level (normalized Lex 8-hr) exceeds 80 dBA-weighted. The American Conference of Governmental Industrial Hygienists' threshold limit value-time weighted average (ACGIH TLV-TWA) for iron is 5.0 mg/m3, manganese is 0.2 mg/m3, carbon monoxide is 25 ppm, and ozone is 0.05 ppm (heavy work), 0.08 ppm (moderate work), and 0.1 ppm (light work). Welders' personal exposures to manganese ranged from 0.01-4.93 mg/m3 (N = 42; AM = 0.5; GM = 0.2; SD +/- 0.9; GSD +/- 3.2) and to iron ranged from 0.04-16.29 mg/m3 (N = 42; AM = 3.0; GM = 1.4; SD +/- 3.5; GSD +/- 2.5). Noise exposures ranged from 79-98 dBA (N = 44; AM = 88.9; GM = 88.8; SD +/- 4.2; GSD +/- 1.0). Carbon monoxide levels were less than 5.0 ppm (at source) and ozone levels varied from 0.4-0.6 ppm (at source). Ventilation upgrades in the workplace were required in most welding shops. Only 7 percent of the welders wore respiratory protection. A hearing conservation program and hearing protection were required at all monitored workplaces.

  2. Performance concerns for high duty fuel cycle

    International Nuclear Information System (INIS)

    Esposito, V.J.; Gutierrez, J.E.


    One of the goals of the nuclear industry is to achieve economic performance such that nuclear power plants are competitive in a de-regulated market. The manner in which nuclear fuel is designed and operated lies at the heart of economic viability. In this sense reliability, operating flexibility and low costs are the three major requirements of the NPP today. The translation of these three requirements to the design is part of our work. The challenge today is to produce a fuel design which will operate with long operating cycles, high discharge burnup, power up-rating and while still maintaining all design and safety margins. European Fuel Group (EFG) understands that to achieve the required performance high duty/energy fuel designs are needed. The concerns for high duty design includes, among other items, core design methods, advanced Safety Analysis methodologies, performance models, advanced material and operational strategies. The operational aspects require the trade-off and evaluation of various parameters including coolant chemistry control, material corrosion, boiling duty, boron level impacts, etc. In this environment MAEF is the design that EFG is now offering based on ZIRLO alloy and a robust skeleton. This new design is able to achieve 70 GWd/tU and Lead Test Programs are being executed to demonstrate this capability. A number of performance issues which have been a concern with current designs have been resolved such as cladding corrosion and incomplete RCCA insertion (IRI). As the core duty becomes more aggressive other new issues need to be addressed such as Axial Offset Anomaly. These new issues are being addressed by combination of the new design in concert with advanced methodologies to meet the demanding needs of NPP. The ability and strategy to meet high duty core requirements, flexibility of operation and maintain acceptable balance of all technical issues is the discussion in this paper. (authors)

  3. Identity-driven differences in stakeholder concerns about hunting wolves. (United States)

    Lute, Michelle L; Bump, Adam; Gore, Meredith L


    Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT) has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet) with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666) cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

  4. Public attitudes toward health information exchange: perceived benefits and concerns. (United States)

    Dimitropoulos, Linda; Patel, Vaishali; Scheffler, Scott A; Posnack, Steve


    To characterize consumers' attitudes regarding the perceived benefits of electronic health information exchange (HIE), potential HIE privacy and security concerns, and to analyze the intersection of these concerns with perceived benefits. A cross-sectional study. A random-digit-dial telephone survey of English-speaking adults was conducted in 2010. Multivariate logistic regression models examined the association between consumer characteristics and concerns related to the security of electronic health records (EHRs) and HIE. A majority of the 1847 respondents reported they were either "very" or "somewhat" concerned about privacy of HIE (70%), security of HIE (75%), or security of EHRs (82%). Concerns were significantly higher (P security, and 60% would permit HIE for treatment purposes even if the physician might not be able to protect their privacy all of the time. Over half (52%) wanted to choose which providers access and share their data. Greater participation by consumers in determining how HIE takes place could engender a higher degree of trust among all demographic groups, regardless of their varying levels of privacy and security concerns. Addressing the specific privacy and security concerns of minorities, individuals 40 to 64 years old, and employed individuals will be critical to ensuring widespread consumer participation in HIE.

  5. Predicting user concerns about online privacy in Hong Kong. (United States)

    Yao, Mike Z; Zhang, Jinguang


    Empirical studies on people's online privacy concerns have largely been conducted in the West. The global threat of privacy violations on the Internet calls for similar studies to be done in non-Western regions. To fill this void, the current study develops a path model to investigate the influence of people's Internet use-related factors, their beliefs in the right to privacy, and psychological need for privacy on Hong Kong people's concerns about online privacy. Survey responses from 332 university students were analyzed. Results from this study show that people's belief in the right to privacy was the most important predictor of their online privacy concerns. It also significantly mediated the relationship between people's psychological need for privacy and their concerns with privacy violations online. Moreover, while frequent use of the Internet may increase concerns about online privacy issues, Internet use diversity may actually reduce such worries. The final model, well supported by the observed data, successfully explained 25% of the variability in user concerns about online privacy.

DOE-ONS identified six areas of concern, with specific findings in each area. The six concerns deal with: (1) Technical Specification surveillance, (2) human factors issues, (3) emergency lighting, (4) fire protection issues, (5) the Unreviewed Safety Question process, and (6) the critique process. This report addresses each of these six concerns and Westinghouse's actions to resolve them

  8. Safety studies concerning nuclear power reactors

    International Nuclear Information System (INIS)

    Bailly, Jean; Pelce, Jacques


    The safety of nuclear installations poses different technical problems, whether concerning pressurized water reactors or fast reactors. But investigating methods are closely related and concern, on the one hand, the behavior of shields placed between fuel and outside and, on the other, analysis of accidents. The article is therefore in two parts based on the same plan. Concerning light water reactors, the programme of studies undertaken in France accounts for the research carried out in countries where collaboration agreements exist. Concerning fast reactors, France has the initiative of their studies owing to her technical advance, which explains the great importance of the programmes under way [fr

  9. Public concerns and alternative nuclear power systems

    International Nuclear Information System (INIS)

    Mayo, L.H.


    The basic task undertaken in this study was to assess the relative public acceptability of three general types of nuclear power systems as alternatives to the existing Light Water Reactor (LWR) system. Concerns registered toward nuclear power constituted the basic data for this assessment. The primary measure adopted for determining the significance of concerns was the degree of difficulty posed by the concern to the nuclear power decisional structure in the establishment and maintenance of norms to control risks or to advance intended energy objectives. Alleviations or exacerbations of concern resulting from particular attributes of alternative systems were measured from an LWR baseline

  11. General experiments concerning particle-matter interactions

    International Nuclear Information System (INIS)

    Dauvergne, D.


    The author gathers in this document several papers he has already published in order to shed light on different aspects concerning ion-crystal interactions. This document is divided into 3 chapters. In the first chapter the author presents results obtained from experiments dedicated to charge exchanges and energy released by heavy ions in channeling conditions. Different processes involved in ion-electron interactions are considered: The tri-electronic recombination, the electron capture through nuclear excitation (NEEC), resonant transfer and excitation (RTE), resonant transfer and double excitation (RTDE) and electron impact ionization (EII). The second chapter deals with the measurement of nuclear fission times through crystal blocking experiments. The crystal blocking technique allows the measurement in a model-independent way of the recoil distance covered by the excited nucleus during the whole fission process (starting from the initial collision and ending at the scission point). The last chapter is dedicated to the photon impact ionization through the conversion of a high-energy photon into an electron-positron pair

  17. What risks are Chinese people concerned about? (United States)

    Xie, Xiaofei; Wang, Mei; Xu, Liancang


    The aim of this study is to investigate public perceived risk on various issues in present-day China. Two surveys were conducted in urban China in 1996 and 1998. In the first survey, risk perceptions of different occupational groups are compared. Gender differences within each occupational group are also analyzed. In the second survey, participants with diverse employment status were recruited. The overall risk rankings of both surveys indicate great concern with risks that threaten national stability and economic development, and less concern with high-technology risk such as threat from a nuclear power plant. It is also found that employees from high-profit firms are more concerned about macroscopic catastrophic risks, whereas laid-off workers and employees from money-losing enterprises are more concerned about daily life or self-concerned risks. The importance of actual exposure to risk, mass media coverage, culture, and psychometric dimensions are discussed.

  18. Dimensions of the epilepsy foundation concerns index. (United States)

    Loring, David W; Larrabee, Glenn J; Meador, Kimford J; Lee, Gregory P


    We performed principal component analysis (PCA) of the Epilepsy Foundation Concerns Index scale in 189 patients undergoing evaluation for epilepsy surgery. We identified a five-factor solution in which there were no varimax-rotated factors consisting of fewer than two questions. Factor 1 reflects affective impact on enjoyment of life, Factor 2 reflects general autonomy concerns, Factor 3 reflects fear of seizure recurrence, Factor 4 reflects concern of being a burden to one's family, and Factor 5 reflects a perceived lack of understanding by others. Multiple regression using the Quality of Life in Epilepsy--89 question version; Minnesota Multiphasic Personality Inventory--2; Wechsler Adult Intelligence Scale--third edition; and verbal and visual memory tests as predictors demonstrated a different pattern of association with the factor and summary scores. We conclude that the Epilepsy Foundation Concerns Index is multidimensional, and using a global score based on all items may mask specific concerns that may be relevant when applied to individual patients.

  20. Examining weight concern and delay discounting in adolescent females. (United States)

    Thamotharan, Sneha; Lange, Krista; Ramos, Ashley; Fields, Sherecce


    Pediatric obesity is a growing public health concern that contributes to high rates of negative long-term physical and mental health outcomes. Research focused on identifying risk for pediatric obesity has linked delay discounting, or an inclination for immediate rewards, as well as weight concern to individuals with greater Body Mass Index (BMI). The current study seeks to fill a void in the literature by examining how these two variables interact to promote higher BMI in female adolescents. Adolescent (n=60) females between the ages of 13-19years (mage=17.45, SD=1.74) of age completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Delay Discounting Questionnaire. A mediation model examined whether delay discounting accounted for the relationship between weight concern and BMI. Results indicate that in the current study weight concern was negatively related to delay discounting and delay discounting was negatively related to BMI. The overall model revealed that a partial mediation occurred [b=1.28, t(60)=4.92, pconcerns contribute to greater BMI. Nevertheless, the results indicate that prevention and interventions should identify females with high levels of both weight concern and impulsivity as an increased risk for experiencing pediatric obesity and long-term negative health outcomes.

  1. Are empathy and concern psychologically distinct? (United States)

    Jordan, Matthew R; Amir, Dorsa; Bloom, Paul


    Researchers have long been interested in the relationship between feeling what you believe others feel-often described as empathy-and caring about the welfare of others-often described as compassion or concern. Many propose that empathy is a prerequisite for concern and is therefore the ultimate motivator of prosocial actions. To assess this hypothesis, the authors developed the Empathy Index, which consists of 2 novel scales, and explored their relationship to a measure of concern as well as to measures of cooperative and altruistic behavior. A series of factor analyses reveal that empathy and concern consistently load on different factors. Furthermore, they show that empathy and concern motivate different behaviors: concern for others is a uniquely positive predictor of prosocial action whereas empathy is either not predictive or negatively predictive of prosocial actions. Together these studies suggest that empathy and concern are psychologically distinct and empathy plays a more limited role in our moral lives than many believe.

  4. Understanding community traits - understanding public concerns

    International Nuclear Information System (INIS)

    Wlodarczyk, T.


    No two communities are alike. Therefore, one should not expect that public concerns and socio-economic effects of a proposed undertaking would be the same everywhere. Public concerns and the potential for social and economic effects of nuclear waste management facilities in one community will be different from those in another because communities differ in their fundamental sociological and economic traits. Research and experience with various types of nuclear and hazardous waste management facilities, generating stations and other energy developments across Canada and the United States indicate that an analysis of only a few key community traits can yield a more thorough understanding of the ways in which a community might perceive and respond to a project, the kinds of concerns that might dominate the public agenda, and the types of socio-economic effects that will be of primary concern.

    Environment concern is one important aspect for supply chain sustainability (SCS). Nowadays, company's activities give a lot of impact on the environment. Through these activities, there are other SCS issue of environment were identified. In this paper, the proposed SCS issue of environmental concern will be determined from Corporate Sustainability Report (CSR). Using a total weightage of 0.333 (after dividing into three aspects of sustainability), each proposed issues will be classified according to the company activities in order to determined weightage for each issue. Those weightages then will be used in developing of score metric for SCS in design phase. Result shows that the carbon footprint is the major concern for SCS of environment while environmental management system is a lowest concern for SCS environment.

  11. Concern for Others Leads to Vicarious Optimism. (United States)

    Kappes, Andreas; Faber, Nadira S; Kahane, Guy; Savulescu, Julian; Crockett, Molly J


    An optimistic learning bias leads people to update their beliefs in response to better-than-expected good news but neglect worse-than-expected bad news. Because evidence suggests that this bias arises from self-concern, we hypothesized that a similar bias may affect beliefs about other people's futures, to the extent that people care about others. Here, we demonstrated the phenomenon of vicarious optimism and showed that it arises from concern for others. Participants predicted the likelihood of unpleasant future events that could happen to either themselves or others. In addition to showing an optimistic learning bias for events affecting themselves, people showed vicarious optimism when learning about events affecting friends and strangers. Vicarious optimism for strangers correlated with generosity toward strangers, and experimentally increasing concern for strangers amplified vicarious optimism for them. These findings suggest that concern for others can bias beliefs about their future welfare and that optimism in learning is not restricted to oneself.

  18. Concern for others leads to vicarious optimism


    Kappes, A.; Faber, N. S.; Kahane, G.; Savulescu, J.; Crockett, M. J.


    An optimistic learning bias leads people to update their beliefs in response to better-than-expected good news but neglect worse-than-expected bad news. Because evidence suggests that this bias arises from self-concern, we hypothesized that a similar bias may affect beliefs about other people’s futures, to the extent that people care about others. Here, we demonstrated the phenomenon of vicarious optimism and showed that it arises from concern for others. Participants predicted the likelihood...

    Repacholi, M.H.


    Although modern offices have traditionally been thought to be among the safest places to work, over the past few years office workers have become concerned that video display terminals could be causing a variety of health problems. Extensive testing has occurred in many countries to determine if VDTs emit hazardous levels of ionizing or non-ionizing radiation. Results of these surveys suggest that radiation emissions are not of concern but that ergonomic factors in the office environment may need to be improved

  20. Understanding parenting concerns in cancer survivors with minor and young-adult children. (United States)

    Inhestern, Laura; Bultmann, Johanna Christine; Beierlein, Volker; Möller, Birgit; Romer, Georg; Koch, Uwe; Bergelt, Corinna


    Parents with cancer are concerned about the impact of their disease on their children. However, parenting concerns and associated factors in cancer survivors have not previously been analyzed. The purpose of this study is to examine parenting concerns and to test a path model for understanding parenting concerns in cancer survivors. In a cross-sectional study, a total of 1416 parents with cancer (mean age 47.5years, 74% women) having minor or young-adult children were recruited through two cancer registries. Parenting concerns were assessed using the Parenting Concerns Questionnaire. Structural equation modeling (SEM) was used to analyze the associations between social support, parenting confidence, emotional distress, family functioning and parenting concerns. Mothers reported higher total parenting concerns than fathers (peffects of emotional distress and parenting confidence on parenting concerns. Family dysfunctioning was associated with lower concerns. An indirect association between social support and parenting concerns was identified. Parenting concerns in cancer survivors display the need for interventions and after care programs that focus on affected families with minor and young adult children. The results of the structural path model illustrate the associations between psychological and interactional factors. Supporting parents with cancer in their parenting confidence and strengthen social support and family functioning may not only reduce the long-term burden on the parents themselves but also the burden on the entire family.

    Michelle L Lute

    Full Text Available Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666 cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

    For the purpose of curtailing energy consumption in the steel industry, a heavy energy consuming industry in Thailand, a model project was carried out for waste heat recovery on a billet reheating furnace, with the fiscal 1999 results compiled. This model project is to install a high efficiency recuperator and the latest combustion control system in the existing furnace in a SISCO (The Siam Iron and Steel Co., Ltd.) plant in Thailand. This year, following the preceding year, the construction manual was prepared, as were the test run manual, performance verification manual, operation and maintenance manual, etc. Supervisors were also dispatched to the site, giving guidance of the installation work, test run and the demonstrative operation, on the basis of these documents. Operation for verifying performance of the equipment was implemented on November 17, 1999, with the intended results obtained. Subsequently, operation maintenance instructors were dispatched, with energy saving effect proved through the collection/analysis of operation data and monitoring, for example. Further, as the dissemination activities, pamphlets and videos were prepared, and seminars were held, among others. (NEDO)

  4. Concern as motivation for protection: an investigation of mothers' concern about daughters' breast cancer risk. (United States)

    Neuberger, Lindsay; Silk, Kami J; Yun, Doshik; Bowman, Nicholas David; Anderson, Jennifer


    The present study surveyed mothers with daughters (N = 386) to investigate how mothers' concern about their daughters' breast cancer risk influenced intentions to engage in preventive behaviors. Using protection motivation theory as a framework, self-efficacy, response efficacy, and level of concern were posited to influence protective behavioral intention in distinct ways. Results from regression analyses indicate that self-efficacy, response efficacy, and mothers' concern are significant predictors of intentions to engage in preventive behaviors with daughters. In addition, a content analysis of mothers' open-ended reasons for their concern about their daughters' breast cancer risk yield a list of specific concerns and trends that vary by concern level and individual comment valence. The authors discuss implications for incorporating mothers' concerns into breast cancer prevention messages as a novel strategy for campaign designers.

  6. Going Concern Disclosure for Local Governments

    Directory of Open Access Journals (Sweden)

    Nancy Chun Feng


    Full Text Available Going concern opinions (GCOs indicate that auditors have significant doubt about an entity’s ability to continue operation one year after the financial statement date. This study addresses the following research questions: What are the factors that motivate auditors to issue GCOs to governmental entities? Does a governmental entity disclose going concern uncertainty in the footnotes or the MD&A section of annual financial reports (AFRs either the year before or the year when the entity receives a GCO? To what extent does the entity disclose the GCO factors used by auditors? We find that auditors most often cited two reasons, “Deficiency in Funds” and “Losses or Revenue Declines,” accounting for the majority of reasons given for a going concern opinion. Further, the disclosure is most likely to be in the notes to the AFRs. In addition, we find that going concern reporting varies by auditor type (state auditors vs. public accounting firms, government size, and government type. We also find some evidence that going concern disclosures improve after the enactment of GASB No. 56. The results of our study should be of interest to stakeholders’ interested in lead indicators of fiscal distress.

  10. Special nutritional concerns for the female athlete. (United States)

    Gabel, Kathe A


    Inadequate dietary intake is the primary nutritional concern of today's female athlete. As these athletes fail to consume enough energy to support the physical demands of training, they become at risk for disordered eating, amenorrhea, and osteoporosis, conditions collectively identified as the female athlete triad. This review addresses nutritional concerns of the female athlete, identification of those at risk, relationship of energy intake to menstrual irregularities, and recently identified chronic diseases associated with the female athlete triad. Strategies are offered to prevent harmful behaviors leading to the comorbidities associated with inadequate dietary intakes.

  11. Ethnic differences in ecological concerns: Spanish-speaking Hispanics are more concerned than others

    International Nuclear Information System (INIS)

    Burger, Joanna; Greenberg, Michael


    We postulated that environmental concern encompasses a wide range of different issues, often lumping pollution with habitat loss (or land use) and ecological resources (fish and wildlife). In this paper, we compare perceptions about a range of environmental and ecological resource issues, and explore ethnic/racial differences. We surveyed 1513 residents of New Jersey about 'environmental concerns', using both general environmental questions (two questions: How serious are environmental problems in New Jersey? Are you concerned about the loss of open space?) and ecological resource questions (12 questions: e.g., how important is planting trees in your neighborhood, how concerned are you about loss of breeding and feeding habitat for fish and birds?) in New Jersey. Not all concerns were rated equally. For the ecological questions, there were no ethnic differences in concerns over preserving areas around water supplies, loss of places to hunt and fish, and loss of places for quiet walks and cycling, but there were for the other 9 ecological concerns. For eight of these nine concerns, Spanish-speaking Hispanics were more concerned than others (including English-speaking Hispanics). We divided the ecological resources into three categories: ecological services (clean water and safety), ecological resources (fish and wildlife), and recreational services. The strongest correlates of people's association with enlarging and enhancing recreational services were Spanish-speaking Hispanics, who are supportive of regulations and believe local government is not doing enough for environmental problems. People concerned about the loss of ecological resources and open space believe the federal government and the state are not doing enough for the environment, were non-Hispanic White, want continued environmental regulations, were longer-term residents, were high school graduates, and were older (45-54 years). People interested in ecological services were college-educated, non

  12. Food concerns and support for environmental food policies and purchasing. (United States)

    Worsley, Anthony; Wang, Wei C; Burton, Melissa


    Consumer support for pro environmental food policies and food purchasing are important for the adoption of successful environmental policies. This paper examines consumers' views of food policy options as their predisposition to purchase pro environmental foods along with their likely demographic, educational and cognitive antecedents including food and environmental concerns and universalism values (relating to care for others and the environment). An online survey to assess these constructs was conducted among 2204 Australian adults in November 2011. The findings showed strong levels of support for both environmental food policies (50%-78% support) and pro environmental food purchasing (51%-69% intending to purchase pro environmental foods). Confirmatory factor analysis and structural equation modelling showed that different cognitive mediators exist along pathways between demographics and the two outcome variables. Support for food policy was positively related to food and environment concerns (std. Beta = 0.25), universalism (0.41), perceived control (0.07), and regulatory issues (0.64 but negatively with food security issues (-0.37). Environment purchasing intentions were positively linked to food and nutrition concerns (0.13), food and environment concerns (0.24), food safety concerns (0.19), food and animal welfare concerns (0.16), universalism (0.25), female gender (0.05), education (0.04), and perceived influence over the food system (0.17). In addition, health study in years 11 and 12 was positively related to the beginning of both of these pathways (0.07 for each). The results are discussed in relation to the opportunities that communications based on the mediating variables offer for the promotion of environmental food policies and purchasing.

  9. What factors mediate the relationship between global self-worth and weight and shape concerns? (United States)

    Murphy, Edel; Dooley, Barbara; Menton, Aoife; Dolphin, Louise


    The primary aim of this study was to investigate whether the relationship between global self-worth and weight concerns and global self-worth and shape concerns was mediated by pertinent body image factors, while controlling for gender and estimated BMI. Participants were 775 adolescents (56% male) aged 12-18years (M=14.6; SD=1.50). Mediation analysis revealed a direct and a mediated effect between global self-worth and two body image models: 1) weight concerns and 2) shape concerns. The strongest mediators in both models were physical appearance, restrained eating, and depression. Partial mediation was observed for both models, indicating that body image factors which span cognitive, affective, and behavioral constructs, explain the association between global self-worth and weight and shape concerns. Implications for future research, weight and shape concern prevention and global self-worth enhancement programs are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    One of the main activities to be undertaken by CNEA will be to provide technological assistance to NASA in problems concerning NPP operation. Works on life extensions of NPP are included in these activities. To fulfill these requirements the Atomic Energy National Commission (CNEA) has constituted a technical committee for Nuclear Power Plants Support (CAPCEN). CAPCEN should be the knowledge reservoir of those issues concerning the performance, safety and life extension of Nuclear Power Plants. One of CAPCEN's most important activities is to promote research work connected with such issues. The main technical areas are: Pressure Vessel and Piping, Heat Exchanges and Fuel Channels and Reactor Inner Components. Efforts are focused on the identification of the main components susceptible of ageing, the study of their ageing mechanisms, the follow-up of their behaviour during operation, and the measures taken to extend their life.

    Vieth, D.L.


    The Governor of Nevada was notified in 1983 that the Yucca Mountain site is a potentially acceptable site for a nuclear waste storage site. A series of public hearings held produced nearly 400 comments on issues concerning the site nomination. Areas of primary public concern are the impact of the proposed nuclear site on tourism, transportation, and socioeconomic impact on adjacent communities. Results of recent studies showed no impact of high-level waste transport on tourism in the Las Vegas area and on analysis of data accumulated over the 25 to 30 years that high-level radioactive wastes have been transported on Nevada highways showed that no one has been evacuated from their home as the result of an accident involving radioactive waste. A comparison of the possible effects of construction of a nuclear waste storage facility at the Yucca mountain site with the effects of Nevada Test Site indicate that the impact on communities will be minimal

  13. Some Behaviorial Science Measurement Concerns and Proposals. (United States)

    Nesselroade, John R; Molenaar, Peter C M


    Primarily from a measurement standpoint, we question some basic beliefs and procedures characterizing the scientific study of human behavior. The relations between observed and unobserved variables are key to an empirical approach to building explanatory theories and we are especially concerned about how the former are used as proxies for the latter. We believe that behavioral science can profitably reconsider the prevailing version of this arrangement because of its vulnerability to limiting idiosyncratic aspects of observed/unobserved variable relations. We describe a general measurement approach that takes into account idiosyncrasies that should be irrelevant to the measurement process but can intrude and may invalidate it in ways that distort and weaken relations among theoretically important variables. To clarify further our major concerns, we briefly describe one version of the measurement approach that fundamentally supports the individual as the primary unit of analysis orientation that we believe should be preeminent in the scientific study of human behavior.

  14. Environmental concerns gaining importance in industry operations

    International Nuclear Information System (INIS)



    This paper reports that environmental concerns have leapt to the forefront of industry's concerns in operating in Latin America. The United Nations Conference on Environment and Development in Rio de Janeiro June 3-14 focused a strong world spotlight on the region's environmental and commercial resources. Protection of the region's rain forests, which accounts for a huge share of the world's total, is emerging as an especially contentious issue. Ecuador's Oriente region may well prove the litmus test of how or whether oil and gas companies are able to operate in Latin American rain forests. Controversy over industry operations in the Oriente have heated to the point that environmentalist and native groups have routinely picketed company offices in Quito and used mass fundraiser mailings in North America

    A pandemic is a human medical problem but must be understood at multiple levels. Analysis of social and commercial forces is vital, and, more comprehensively, an ecological framework is necessary for an inclusive picture. Ecological health webworked with political and social determinants surrounds issues of human health. In this constellation of both natural and social factors, ethical concerns will arise at these multiple levels, from human health to the conservation and health of wild nature.

    The objectives of the present research are related to the approaches concerning the “performance audit” concept in the specialized literature and practice as well as the clear delimitation of this concept of financial audit and internal audit. For a clear emphasis of the objectives and principles of the performance audit, I highlighted the similarities and differences among the three types of audit by means of several criteria such as: audit standards, audited subjects, nature of the audit ev...

  20. The Auditor's Going-Concern Opinion Decision


    Tae G. Ryu; Chul-Young Roh


    In this study, we expand on several previous studies related to the materiality judgments and the auditor's propensity to issue a going-concern opinion to financially troubled but non-bankrupt companies. We test the auditor's materiality thresholds by investigating whether there is any significant difference in accuracy among audit firms, especially between Big Six (Five) and non-Big Six (Five) audit firms. Binary logit regression is used to analyze 1,332 firms that were non-bankrupt but fina...

  1. Below regulatory concern - or simply exempt?

    International Nuclear Information System (INIS)

    Brodsky, A.


    The US Nuclear Regulatory Commission published a policy statement last summer on ''below regulatory concern'' (BRC), which exempted small quantities of radioactive material from regulatory control and would allow the deregulated disposal of some low level waste. The policy drew opposition from several groups. NRC is not planning to revise its BRC policy statement, but wants to develop a concensus on how to implement the policy. Although the Commission's publication of a long needed policy framework for guiding exemption decisions should be welcomed by those of us who have been concerned with making such decisions, there is an urgent need for further consensus building. The policy statement offers only broad guidelines, some of which could be confusing and seem contradictory. The policy statement by itself could further erode public confidence in the NRC's commitment to specific limits of risk, and the ability of its staff to independently evaluate the risks. Another reason why it is appropriate and urgent to embark upon consensus building involving all parties and the public, is that the risks of low level radioactive waste disposal as practiced and proposed in the United States have long been exaggerated in biased reports that receive most media attention. A consensus process needs to be established so that the public can have confidence that its concerns have been properly addressed. (author)

  2. Environmental Concerns, Environmental Policy and Green Investment. (United States)

    Gao, Xuexian; Zheng, Haidong


    Environmental regulators often use environmental policy to induce green investment by firms. However, if an environmental policy fails to exert a long-run effect on regulating the economic agents' behavior, it may be more reasonable to think of the firm as the leader in the game, since the investment in green technology is usually a strategic decision. In this paper, we consider a three-stage Stackelberg game to address the interaction between a profit-maximizing firm (Stackelberg leader) facing emission-dependent demand, and the environmental regulator (Stackelberg follower). The firm decides on the green technology level in the first stage of the game based on its understanding of the regulator's profits function, especially an environmental concern that is introduced as an exogenous variable. In the current research, we show that high levels of the regulator's environmental concerns do not necessarily lead to the choice of green technology by the firm, and green investment level depends on the combined effects of the market and operational factors for a given level of the regulator's environmental concerns. The result also shows that increasing environmental awareness amongst the consumers is an effective way to drive the firm's green investment.

    Full Text Available Understanding consumer behaviour in online environments is the basic factor to build an effective consumer-retailer relationship structure. The purpose of this study is to explore the influences of different values and concerns affecting search and purchase intentions of consumers and to build an integrated model, which could explain the purchase intentions of consumers in Turkey, where the majority of the population is under the age of 30. An integrated model of motivation and concern factors on the online shopping is developed to test the causal effect variables. Current study points out that hedonic value is a determinant of the consumer intention to search and purchase. Search intention has a direct impact on purchase intention. Utilitarian value does not have a significant impact on the search intention but it does have an important impact on the purchase intention. From the concern factors perspective, security has a significant impact on both search and purchase intentions, whereas there is no impact for privacy.

  5. Psychological treatment of social anxiety disorder improves body dysmorphic concerns. (United States)

    Fang, Angela; Sawyer, Alice T; Aderka, Idan M; Hofmann, Stefan G


    Social anxiety disorder and body dysmorphic disorder are considered nosologically distinct disorders. In contrast, some cognitive models suggest that social anxiety disorder and body dysmorphic disorder share similar cognitive maintenance factors. The aim of this study was to examine the effects of psychological treatments for social anxiety disorder on body dysmorphic disorder concerns. In Study 1, we found that 12 weekly group sessions of cognitive-behavioral therapy led to significant decreases in body dysmorphic symptom severity. In Study 2, we found that an attention retraining intervention for social anxiety disorder was associated with a reduction in body dysmorphic concerns, compared to a placebo control condition. These findings support the notion that psychological treatments for individuals with primary social anxiety disorder improve co-occurring body dysmorphic disorder symptoms.

    He, Jianhong; Zhang, Lei; Lu, Binbin; Li, Lin


    This paper studies the pricing strategy in the closed-loop supply chain with Nash bargaining when considering fairness concerns and risk aversion. Mainly, the authors argue that behavioral factors (i.e., fairness concern and risk aversion) should be introduced into pricing process. They consider three different pricing models: the first is that both manufacturer and retailer have fairness concern; the second is both manufacturer and retailer have risk aversion and the final is manufacturer ha...

  9. General and smoking cessation weight concern in a Hispanic sample of light and intermittent smokers. (United States)

    Landrau-Cribbs, Erica; Cabriales, José Alonso; Cooper, Theodore V


    This study assessed general and cessation related weight concerns in a Hispanic sample of light (≤10 cigarettes per day) and intermittent (non-daily smoking) smokers (LITS) participating in a brief smoking cessation intervention. Three hundred and fifty-four Hispanic LITS (Mage=34.2, SD=14; 51.1% male; 57.9% Mexican American; 59.0% daily light, 41.0% intermittent) completed baseline measures assessing demographics, tobacco use/history, stage of change (SOC), general weight concern, and cessation related weight concern. Three multiple logistic regression models examined potential predictors (i.e., age, gender, SOC, cigarettes per month, smoking status [daily vs non-daily], weight, cessation related weight concern, general weight concern) of general weight concern, cessation related weight concern, and past 30day abstinence (controlling for the intervention). Study results indicated that a majority of participants reported general weight concern (59.6%), and slightly more than a third (35.6%) reported post cessation weight gain concern (mean and median weight tolerated before relapse were within the 10-12lb range). Lower weight and endorsing general weight concern were associated with cessation related weight concern. Female gender, higher weight, and endorsing cessation related weight concern were associated with general weight concern. Monthly cigarette use was associated with smoking cessation at the three-month follow-up. The results indicate a substantial prevalence of general weight concern and non-trivial rates of cessation related weight concern in Hispanic LITS attempting to quit, and greater success in quitting among those who reported lower rates of cigarettes smoked per month.

  10. Ionising Radiation and Cabin Crew Concerns

    International Nuclear Information System (INIS)

    Balouet, J.C.


    The trend in flying at higher altitudes and latitudes results in increased exposure to cosmic radiation. The biological incidence of highest energy particles and heavy ions is not well documented. Crew members flying transpolar routes are already exposed to levels of about 6 mSv.y -1 , and are expected to exceed this level in a number of cases. Epidemiological studies are important in risk assessment. Organisation of monitoring campaigns, aircrew information, solar flares and related high levels of exposures, pregnancy related issues, medical control, recognition of occupational exposure during illness, including cancer cases, and social protection, are also major concerns.

  12. Nanotechnology in medicine: concepts and concerns

    International Nuclear Information System (INIS)

    Cancino, Juliana; Marangoni, Valeria S.; Zucolotto, Valtencir


    The recent advances in the development of nanomaterials have opened new and exciting opportunities for their applications in medicine. These applications include molecular imaging, drug-delivery, and photothermal therapy. Despite the progress in medicinal applications of nanomaterials, several key problems remain unaddressed. Recent advances in this area include the enhancement of sensitivity in early diagnosis and therapy, in addition to investigations into the possible toxicity of nanomaterials. However, since little is known about the toxicity of nanomaterials, the regulation of these materials is a slow and complex process. This paper reviews the current scenario in the applications of nanomaterials in medicine as well as the main concerns and regulatory questions. (author)

  15. Radiation safety concerns during interventional radiology

    International Nuclear Information System (INIS)

    Victor Raj, D.; Livingstone, Roshan Samuel


    Interventional radiological procedures are on the increase by virtue of the fact that these procedures replace highly invasive surgical and other procedures. Radiation dose to patients and hospital workers are of significance since these procedures tend to impart large dose to them. Moreover, long term risk from radiation absorbed by patients is of concern since the life expectancy of major fraction of patients is long after undergoing the procedure. This study intends to measure radiation dose imparted to patients as well as personnel- radiologists, technologists, nurses, etc. and estimate the risk factor involved

  16. Genital size: a common adolescent male concern. (United States)

    Lee, Peter A; Reiter, Edward O


    Long before adolescence, males hear insinuations about adequacy of penis size. This concern may heighten during teen years and persist to varying degrees into adulthood. Men tend to underestimate their own penis size. This chapter provides objective information about anatomy and growth of the penis, including data about normal sizes. Published data indicate that, although full growth may be reached at different ages during adolescence, size is similar for most adult males. Hopefully, this information will provide the basis for teenaged males to develop a healthy perspective and to avoid intimidation by unfounded claims about sexual enhancement or size enlargement techniques.

  17. Adolescent homosexuality and concerns regarding disclosure. (United States)

    Harrison, Therese W


    Development of sexual identity in middle childhood and early adolescence is a natural process. However, it is more stressful for homosexual adolescents. Society continues to stigmatize and marginalize homosexuality. To avoid rejection and hostility, homosexual adolescents are pressured to hide their sexual identities. This fact compounds the anticipated normal developmental concerns of adolescence, and can create unique problems for the homosexual adolescents. Homosexuality can place them at risk for social stigmatization, isolation, depression, suicide, abuse, and rejection by their families and friends. During this exceptionally stressful time, both adolescent students and their families need anticipatory guidance and support. In providing anticipatory guidance, this article discusses critical roles played by professionals who work with adolescents in community or school settings. Included are insights into development of this normal variant of sexual attraction and orientation, risks that homosexual adolescent students may face as well as their disclosure concerns, and possible reactions families may have following disclosure. Supporting homosexual adolescents and their families is emphasized with regard to sensitively providing information, disclosure decisions, coping with stigmatization, and resiliency factors.

  18. The law concerning indemnification of nuclear damage

    International Nuclear Information System (INIS)


    This Law aims at determining the basic system concerning indemnification for nuclear damage caused by the operation of reactors, fabrication, reprocessing and use of nuclear fuel materials as well as the transportation, storing or disposal of such materials or those contaminated by such materials (including fission products) accompanying these operations in view of protecting the sufferers and contributing to the wholesome development of atomic energy enterprises. The ''nuclear damage'' referred to in this Law is the damages caused by the action during the process of fission of nuclear fuel materials or the action of radiation or the poisonous action of said nuclear fuel materials or matters contaminated by said materials (those causing poisoning or deuteropathy in human bodies by taking in or inhaling such materials). Upon giving nuclear damage by the operation of reactors and others, the atomic energy entrepreneurs concerned are responsible for indemnifying the damage. Atomic energy entrepreneurs should not operate reactors without first taking the measures for indemnifying nuclear damages. Said measures are conclusion of nuclear damage indemnification responsibility insurance contract and nuclear damage indemnification contract or deposit, by which 6,000 million yen may be earmarked for such indemnification per factory, place of business or nuclear ship

  19. European Union concerns with its energy dependence

    International Nuclear Information System (INIS)

    Commeau, N.


    European Union (E.U.) produces only half its needs concerning energy. It is expected that by 2030, the energy balance will be 86% for fossil energies, 8% for renewable energies and 6% for nuclear energy. Different scenario show that the dependence of E.U will worsen and reach 70% unless a common strategy is launched to curb the tendency. E.U is elaborating a common policy concerning energy, this policy rests on 4 axis: 1) monitoring the increase of the energy consumption by promoting energy savings in housing and transport, 2) directing the energy demand towards less polluting energy by using taxes, public funding and European regulations as incentive tools, 3) sustaining a constant dialogues with energy exporting countries in order to get a more stable energy market and have a benefiting influence on prices, and 4) developing new routes of importation of energy by for instance contributing to the construction of new oil or gas pipeline networks.

  1. Cessation-related weight concern among homeless male and female smokers. (United States)

    Pinsker, Erika Ashley; Hennrikus, Deborah Jane; Erickson, Darin J; Call, Kathleen Thiede; Forster, Jean Lois; Okuyemi, Kolawole Stephen


    Concern about post-cessation weight gain is a barrier to making attempts to quit smoking; however, its effect on smoking cessation is unclear. In this study we examine cessation-related weight concern among the homeless, which hasn't been studied. Homeless males (n = 320) and females (n = 110) participating in a smoking cessation RCT in the Twin Cities, Minnesota from 2009 to 2011 completed surveys on cessation-related weight concern, smoking status, and components from the Behavioral Model for Vulnerable Populations. Generalized estimating equations were used to examine baseline predictors of cessation-related weight concern at baseline, the end of treatment, and 26-weeks follow-up. Logistic regression models were used to examine the relationship between cessation-related weight concern and smoking status at the end of treatment and follow-up. Females had higher cessation-related weight concern than males. Among males, older age, Black race, higher BMI, depression, and having health insurance were associated with higher cessation-related weight concern. Among females, nicotine dependence, greater cigarette consumption, indicating quitting is more important, older age of smoking initiation, and less support to quit from family were associated with higher cessation-related weight concern. In multivariate analyses, cessation-related weight concern decreased over time among females. Cessation-related weight concern wasn't associated with smoking cessation. Although several types of characteristics predicted cessation-related weight concern among males, only smoking characteristics predicted cessation-related weight concern among females. Given the small proportion of quitters in this study (8% of males and 5% of females), further research on the impact of cessation-related weight concern on smoking cessation among the homeless is warranted.

  4. C. Linnaeus' ideas concerning retribution and fate

    Directory of Open Access Journals (Sweden)

    K. Rob. V. Wikman


    Full Text Available Linnæus' Nemesis divina has been interpreted in different ways. Crucial is its central problem: the ideas of fate and retribution, but these are, in turn, dependent on Linnæus' conception of God and nature and not least on his opinions concerning the unity and coherence of the natural and ethical order of the world. From whatever sources Linnæus may have derived his religious ideas and whatever changes they may have undergone, his religious attitude in face of the works of nature remained unshaken. But Linnæus' religion, as we find it fragmentarily in these literary sources, was entirely undogmatic, untheological and, from a Christian point of view, even heterodox. Partly, this was in accord with his belief in the necessary immanent coherence in the processes of nature and the concomitant idea of the righteous divine order of the world.

    After placing the development work on reactivity accidents in the various actions decided upon further to the Chernobyl accident, this note describes the first results obtained and the further developments. As a general rule, the Chernobyl accident has not provided, from a strictly technical viewpoint, any fundamentally new material which had previouly been unknown. Analysis have made it possible to more clearly establish the safety importance of certain operating rules, in particular concerning handling whithin coolant system pumps. They have not show the need to modify the design of the french PWR.s.

  6. Evaluating minerals of environmental concern using spectroscopy (United States)

    Swayze, G.A.; Clark, R.N.; Higgins, C.T.; Kokaly, R.F.; Livo, K. Eric; Hoefen, T.M.; Ong, C.; Kruse, F.A.


    Imaging spectroscopy has been successfully used to aid researchers in characterizing potential environmental impacts posed by acid-rock drainage, ore-processing dust on mangroves, and asbestos in serpentine mineral deposits and urban dust. Many of these applications synergistically combine field spectroscopy with remote sensing data, thus allowing more-precise data calibration, spectral analysis of the data, and verification of mapping. The increased accuracy makes these environmental evaluation tools efficient because they can be used to focus field work on those areas most critical to the research effort. The use of spectroscopy to evaluate minerals of environmental concern pushes current imaging spectrometer technology to its limits; we present laboratory results that indicate the direction for future designs of imaging spectrometers.

  7. Certain problems concerning wavelets and wavelets packets

    International Nuclear Information System (INIS)

    Siddiqi, A.H.


    Wavelets is the outcome of the synthesis of ideas that have emerged in different branches of science and technology, mainly in the last decade. The concept of wavelet packets, which are superpositions of wavelets, has been introduced a couple of years ago. They form bases which retain many properties of wavelets like orthogonality, smoothness and localization. The Walsh orthornomal system is a special case of wavelet packet. The wavelet packets provide at our disposal a library of orthonormal bases, each of which can be used to analyze a given signal of finite energy. The optimal choice is decided by the entropy criterion. In the present paper we discuss results concerning convergence, coefficients, and approximation of wavelet packets series in general and wavelets series in particular. Wavelet packet techniques for solutions of differential equations are also mentioned. (author). 117 refs

  8. Natural History Specimen Digitization: Challenges and Concerns

    Directory of Open Access Journals (Sweden)

    Ana Vollmar


    Full Text Available A survey on the challenges and concerns invovled with digitizing natural history specimens was circulated to curators, collections managers, and administrators in the natural history community in the Spring of 2009, with over 200 responses received. The overwhelming barrier to digitizing collections was a lack of funding, based on a limited number of sources, leaving institutions mostly responsible for providing the necessary support. The uneven digitization landscape leads to a patchy accumulation of records at varying qualities, and based on different priorities, ulitimately influencing the data's fitness for use. The survey also found that although the kind of specimens found in collections and their storage can be quite varible, there are many similar challenges when digitizing including imaging, automated text scanning and parsing, geo-referencing, etc. Thus, better communication between domains could foster knowledge on digitization leading to efficiencies that could be disseminated through documentation of best practices and training.

  9. Caffeinated alcohol beverages: a public health concern. (United States)

    Attwood, Angela S


    Consumption of alcohol mixed with caffeinated energy drinks is becoming popular, and the number of pre-mixed caffeinated alcohol products on the worldwide market is increasing. There is public health concern and even occasional legal restriction relating to these drinks, due to associations with increased intoxication and harms. The precise nature and degree of the pharmacological relationship between caffeine and alcohol is not yet elucidated, but it is proposed that caffeine attenuates the sedative effects of alcohol intoxication while leaving motor and cognitive impairment unaffected. This creates a potentially precarious scenario for users who may underestimate their level of intoxication and impairment. While legislation in some countries has restricted production or marketing of pre-mixed products, many individuals mix their own energy drink-alcohol 'cocktails'. Wider dissemination of the risks might help balance marketing strategies that over-emphasize putative positive effects.

  11. Some Findings Concerning Requirements in Agile Methodologies (United States)

    Rodríguez, Pilar; Yagüe, Agustín; Alarcón, Pedro P.; Garbajosa, Juan

    Agile methods have appeared as an attractive alternative to conventional methodologies. These methods try to reduce the time to market and, indirectly, the cost of the product through flexible development and deep customer involvement. The processes related to requirements have been extensively studied in literature, in most cases in the frame of conventional methods. However, conclusions of conventional methodologies could not be necessarily valid for Agile; in some issues, conventional and Agile processes are radically different. As recent surveys report, inadequate project requirements is one of the most conflictive issues in agile approaches and better understanding about this is needed. This paper describes some findings concerning requirements activities in a project developed under an agile methodology. The project intended to evolve an existing product and, therefore, some background information was available. The major difficulties encountered were related to non-functional needs and management of requirements dependencies.

    Full Text Available This paper offers a definition of the intellectual covering both professional and moral dimensions: An intellectual is a specialist who creates and communicates symbolised knowledge as means of living, and hopefully intervenes in social and political affairs in the name of universal values, truth and justice. "Symbolised knowledge" is used in the definition to avoid the confusion with other forms of knowledge derived from direct personal experience in production and life. The purpose of using "specialist" as the subject term is to exclude those categories such politicians, soldiers and business people who exercise political, military, financial and other forms of power instead of intellectual power in their social function. This paper argues that there are many roles played by intellectuals, and the social location and function of intellectuals can be fundamentally different in different societies. When production and communication of knowledge are taken as the primary concern of intellectuals, ‘the death of the concerned intellectual’ becomes an unwarranted anxiety, because there is no reason to believe that knowledge and truth will no longer be pursued and valued by humankind. Political marginalisation of critical intellectuals, where it is a reality, seems to be caused not so much by the lack of power of intellectuals as by the lack of solidarity among intellectuals to fight for a common cause. The problem lies as much in the lack of enthusiasm among intellectuals to transcend the boundaries of their professional relevance and intervene in broad social and political issues, as in institutional structures consuming too much energy and time of the intellectuals and seducing them to give up their social responsibilities for personal career.

  18. International codes concerning the security of radioisotopes

    International Nuclear Information System (INIS)

    Kusama, Keiji


    Explained is the title subject with international and Japanese official argument or publications and actions, where the security is defined as protection of sealed and unsealed radioisotopes (RI) from malicious acts. IAEA worked out the Code of Conduct on the Safety and Security of Radioactive Sources in 2004 based on its preceding argument and with the turning point of the terrorism 3.11 (2001), and Nuclear Security Recommendations on radioactive material and associated facilities (2011), for whose prerequisite, Security of radioactive sources: implementing guide (2009) and Security in the transport of radioactive material (2008) had been drawn up. The Code of Conduct indicates the security system to regulate the sealed sources that each nation has to build up through legislation, setup of regulatory agency, registration of the sources, provision of concerned facilities with radiation protection, etc. For attaining this purpose, IAEA defined Guidance on the Import and Export of Radioactive Sources (2005, 2012), Categorization of radioactive sources (2005) and Dangerous quantities of radioactive material (D-VALUES) (2006). For updating the related matters, IAEA holds international conferences somewhere in the world every year. The Nuclear Security Recommendations indicate the nation's responsibility of building up and maintaining the security system above with well-balanced measures between the safe and secure use of RI without the invalid inhibition of their usage. Japan government worked out the concept essential for ensuring the nuclear security in Sep. 2011, in which for RI, defined were the risk and benefit in use and security, and securing role of the present legal systems concerning the safety handling and objective RI involved in their registration system. Securing measures of RI in such usage as medical and industrial aids must be of advanced usefulness and safety in harmony with activities of other countries. (T.T)

  19. Concerns About Lung Cancer Among Prisoners. (United States)

    Renault, Luc; Perrot, Emmanuel; Pradat, Eric; Bartoli, Christophe; Greillier, Laurent; Remacle-Bonnet, Anne; Telmon, Norbert; Mazières, Julien; Molinier, Laurent; Couraud, Sébastien


    Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients. We performed a multi-center observational case-control study. Cases were prisoners diagnosed with lung cancer from 2005 to 2013. Controls were non-prisoner lung cancer patients selected from hospital databases and randomly matched to cases (targeted case-control ratio: 1:3). Incidence rates in both groups were calculated using national statistics. Seventy-two cases and 170 controls met inclusion criteria. Cases were mainly men (99%). Mean age at diagnosis was 52.9 (± 11.0) in cases and 64.3 (± 10.1) in controls (p < 0.0001). More case patients were current smokers compared to control patients (83% vs 53%; p < 0.0001). We found no significant differences between the two groups as concerns histologic types, TNM stages at diagnosis, initially-employed treatments, times to management or survival. Incidence rates (2008-2012) in male prisoners were higher than those in the general population in all concerned age groups. There is a shift of lung cancer toward young people in prisons. However, the presentation, management, and prognosis of lung cancer are similar between prisoners and non-prisoners. These finding could justify a specific screening policy for the incarcerated populations.

  20. The association between early generative concern and caregiving with friends from early to middle adolescence. (United States)

    Lawford, Heather L; Doyle, Anna-Beth; Markiewicz, Dorothy


    Generativity, defined as concern for future generations, is theorized to become a priority in midlife, preceded by a stage in which intimacy is the central issue. Recent research, however, has found evidence of generativity even in adolescence. This longitudinal study explored the associations between caregiving in friendships, closely related to intimacy, and early generative concern in a young adolescent sample. Given the importance of close friendships in adolescence, it was hypothesized that responsive caregiving in early adolescent friendships would predict later generative concern. Approximately 140 adolescents (56 % female, aged 14 at Time 1) completed questionnaires regarding generative concern and responsive caregiving with friends yearly across 2 years. Structural equation modeling revealed that caregiving predicted generative concern 1 year later but generative concern did not predict later caregiving. These results suggest that caregiving in close friendships plays an important role in the development of adolescents' motivation to contribute to future generations.

  1. Concern for Lost Income Following Donation Deters Some Patients From Talking to Potential Living Donors. (United States)

    Rodrigue, James R; Schold, Jesse D; Mandelbrot, Didier A; Taber, David J; Phan, Van; Baliga, Prabhakar K


    Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

  3. Reporter Concerns in 300 Mode-Related Incident Reports from NASA's Aviation Safety Reporting System (United States)

    McGreevy, Michael W.


    A model has been developed which represents prominent reporter concerns expressed in the narratives of 300 mode-related incident reports from NASA's Aviation Safety Reporting System (ASRS). The model objectively quantifies the structure of concerns which persist across situations and reporters. These concerns are described and illustrated using verbatim sentences from the original narratives. Report accession numbers are included with each sentence so that concerns can be traced back to the original reports. The results also include an inventory of mode names mentioned in the narratives, and a comparison of individual and joint concerns. The method is based on a proximity-weighted co-occurrence metric and object-oriented complexity reduction.

  4. Concerns in Marine Renewable Energy Projects

    Energy Technology Data Exchange (ETDEWEB)

    Kramer, Sharon; Previsic, Mirko; Nelson, Peter; Woo, Sheri


    To accelerate the adoption of these emerging marine hydrokinetic technologies, navigational and environmental issues and concerns must be identified and addressed. As hydrokinetic projects move forward, various stakeholders will need to be engaged; one of the key issues that project proponents face as they engage stakeholders is that many conflicting uses and environmental issues are not well-understood. Much of this lack of understanding comes from a limited understanding of the technologies themselves. To address this issue, in September 2008, RE Vision consulting, LLC, was selected by the Department of Energy, under their market acceleration program, to apply a scenario-based assessment approach to the emerging hydrokinetic technology sector. The goal was to improve understanding of potential environmental and navigation impacts of these technologies and focus stakeholders on the critical issues. To meet this goal, the study established baseline scenarios for wave and tidal power conversion at potential future deployment sites. The scenarios captured variations in technical approaches and deployment scales and thus grounded the analysis in realistic constraints. The work conducted under this award provides an important foundation to other market acceleration activities carried out by the DOE and other stakeholders in this sector. The scenarios were then evaluated using a framework developed by H.T. Harvey & Associates to identify and characterize key environmental concerns and uncertainties. In collaboration with PCCI and the U.S. Coast Guard, navigation issues were assessed and guidelines developed to assure the safe operation of these systems. Finally, the work highlights “next steps” to take to continue development and adoption of marine hydrokinetic energy. Throughout the project, close collaboration with device developers, project developers and regulatory stakeholders was pursued to ensure that assumptions and constraints are realistic.

  7. Regulations concerning liability, financial security, and the financing of decommissioning

    International Nuclear Information System (INIS)

    Mutschler, U.


    It is self-evident that any sensible reform in the area of liability has to work from the concern for the protection of the injured parties. After the introduction of unlimited liability in 1985 the only remaining starting point for improving the position of an assumed injured partly is that of provision of funds. In view of the responsibility of the respective consative parties for the spheres concerned it is the task of the state and the industry to raise sufficient provision funds to meet the requirements for the protection of the injured parties. Prompted by the existence of corresponding models in foreign legal systems, decommissioning provisions have been discovered as a new field of atomic energy law requiring regularization. Model considerations on how to improve decommissioning provisions show that legislative action is not required to achieve the desired aim. Financial provisions are regularizable solely on the basis of the law in force. Changes are required neither in atomic energy law nor in commercial law nor in tax law. (orig./HSCH) [de

  8. Three dialogues concerning robots in elder care. (United States)

    Metzler, Theodore A; Barnes, Susan J


    The three dialogues in this contribution concern 21st century application of life-like robots in the care of older adults. They depict conversations set in the near future, involving a philosopher (Dr Phonius) and a nurse (Dr Myloss) who manages care at a large facility for assisted living. In their first dialogue, the speakers discover that their quite different attitudes towards human-robot interaction parallel fundamental differences separating their respective concepts of consciousness. The second dialogue similarly uncovers deeply contrasting notions of personhood that appear to be associated with respective communities of nursing and robotics. The additional key awareness that arises in their final dialogue links applications of life-like robots in the care of older adults with potential transformations in our understandings of ourselves - indeed, in our understandings of the nature of our own humanity. This series of dialogues, therefore, appears to address a topic in nursing philosophy that merits our careful attention. © 2013 John Wiley & Sons Ltd.

  9. Female feticide in India: Issues and concerns

    Directory of Open Access Journals (Sweden)

    Garg S


    Full Text Available The preference for a son continues to be a prevalent norm in the traditional Indian household. This is evident from the declining sex ratio which has dropped to alarming levels, especially in the northern states according to Census 2001 reports. The proliferation and abuse of advanced technologies coupled with social factors contributing to the low status of women such as dowry, concerns with family name and looking up to the son as a breadwinner has made the evil practice of female feticide to become common in the middle and higher socioeconomic households, especially in the northern states. Despite the existence of the Prenatal Diagnostic Techniques Act, there is a dire need to strengthen this law since the number of convictions is despairingly low as compared to the burden posed by this crime. Moreover, it is necessary to gear efforts against the cultural, economic and religious roots of this social malady by woman empowerment and intensive Information, Education and Communication campaigns. The medical colleges and professional bodies have a vital role to play by sensitizing medical students who are the doctors of tomorrow.

  10. Concerning the justiciability of demand forecasts

    International Nuclear Information System (INIS)

    Nierhaus, M.


    This subject plays at present in particular a role in the course of judicial examinations of immediately enforceable orders for the partial construction licences of nuclear power plants. The author distinguishes beween three kinds of forecast decisions: 1. Appraising forecast decisions with standards of judgment taken mainly from the fields of the art, culture, morality, religion are, according to the author, only legally verifyable to a limited extent. 2. With regard to forecast decisions not arguable, e.g. where the future behaviour of persons is concerned, the same should be applied basically. 3. In contrast to this, the following is applicable for programmatic, proceedingslike, or creative forecast decisions, in particular in economics: 'An administrative estimation privilege in a prognostic sense with the consequence that the court has to accept the forecast decision which lies within the forecast margins and which cannot be disproved, and that the court may not replace this forecast decision by its own probability judgment. In these cases, administration has the right to create its own forecast standards.' Judicial control in these cases was limited to certain substantive and procedural mistakes made by the administration in the course of forecast decision finding. (orig./HP) [de

  12. The law concerning indemnification of nuclear damage

    International Nuclear Information System (INIS)


    The law defines the basic system of indemnification of nuclear damage by the operation of reactors to protect sufferers and help the sound development of atomic energy business. The operation of reactors means hereunder the operation of reactors, processing, reprocessing and the uses of nuclear fuel materials as well as transport, storage and disposal of nuclear fuel materials or things contaminated by them, which accompany with those procedures. The nuclear damage signifies injuries due to functions of fission of nuclear fuel materials or radiation or poisonous functions of things contaminated by them. When nuclear damage happens by the operation of reactors, the atomic energy enterpriser concerned shall indemnify the damage. Atomic energy undertakers shall not operate reactors without taking measures for compensation. The measures shall be the conclusion of nuclear damage compensation insurance contracts and indemnification contracts or the deposit. The amount of less than yen 10 milliards specified by the order and acknowledged by the Director General of Science and Technology Agency shall be allotted to the compensation by these measures for each works, enterprise or nuclear ship. The government shall assist atomic energy enterprisers to indemnify, when such compensation surpasses the amount assigned and the support is considered necessary. (Okada, K.)

  13. Resolving issues concerning Eskdalemuir geomagnetic hourly values

    Directory of Open Access Journals (Sweden)

    S. Macmillan


    Full Text Available The hourly values of the geomagnetic field from 1911 to 1931 derived from measurements made at Eskdalemuir observatory in the UK, and available online from the World Data Centre for Geomagnetism at, have now been corrected. Previously they were 2-point averaged and transformed from the original north, east and vertical down values in the tables in the observatory yearbooks. This paper documents the course of events from discovering the post-processing done to the data to the final resolution of the problem. As it was through the development of a new index, the Inter-Hour Variability index, that this post-processing came to light, we provide a revised series of this index for Eskdalemuir and compare it with that from another European observatory. Conclusions of studies concerning long-term magnetic field variability and inferred solar variability, whilst not necessarily consistent with one another, are not obviously invalidated by the incorrect hourly values from Eskdalemuir. This series of events illustrates the challenges that lie ahead in removing any remaining errors and inconsistencies in the data holdings of different World Data Centres.

  14. Hypochondriacal concerns and somatization in panic disorder. (United States)

    Furer, P; Walker, J R; Chartier, M J; Stein, M B


    To clarify the relationship between panic disorder and the symptoms of hypochondriasis and somatization, we evaluated these symptoms and diagnoses in patients attending an Anxiety Disorders Clinic. Structured clinical interviews, self-report measures, and symptom diaries were used to assess 21 patients with panic disorder, 23 patients with social phobia, and 22 control subjects with no psychiatric disorders. Ten of the patients with panic disorder (48%) also met DSM-IV criteria for hypochondriasis, whereas only one of the patients with social phobia and none of the healthy control subjects met the criteria for this diagnosis. None of the participants met DSM-IV criteria for somatization disorder, even though both anxiety groups reported high levels of somatic symptoms. The panic disorder group reported higher levels of fear about illness and disease conviction and endorsed more somatic symptoms than did the other groups. A higher proportion of panic disorder patients reported previously diagnosed medical conditions (48%) as compared with patients with social phobia (17%) or healthy control subjects (14%). The panic disorder patients with DSM-IV hypochondriasis obtained higher scores on measures of hypochondriacal concerns, somatization, blood-injury phobia, and general anxiety and distress than did the panic disorder patients without hypochondriasis. The results suggest a strong association between panic disorder and hypochondriasis.

  15. Denture plaque--past and recent concerns. (United States)

    Nikawa, H; Hamada, T; Yamamoto, T


    This paper critically reviews the history of denture plaque and identifies some concerns with the presence of Candida in the mouth. This review covers literature sources related to Candida albicans and its relationship to denture plaque. The articles selected for this review are from referred journals and describe C. albicans and its relationship to oral, gastrointestinal and pleuropulmonary infections. The relationship to caries, root caries and periodontal disease is also covered. Denture plaque containing Candida could cause not only oral candidiasis, like oral thrush or denture-induced stomatitis, but also caries, root caries and periodontitis of abutment teeth. However, there is only limited experimental evidence or information available on the cariogenicity of Candida. The continuous swallowing or aspiration of micro-organisms from denture plaque exposes patients, particularly the immunocompromised host or medicated elderly, to the risks of unexpected infections. The term, 'denture plaque' has been used throughout the review. However, the term 'plaque on denture' should be used because the microbial flora and its pathogenicity of denture plaque resembles those of plaque formed on the tooth surface, so called dental plaque. In addition, the term 'denture related stomatitis' would be preferable to 'denture induced stomatitis', since the inflammation of (palatal) mucosa is not induced by the denture, but by wearing the denture or by plaque on the denture.

  17. Benchmarketing - Fashionable Term Concerning Traditional Processes

    Directory of Open Access Journals (Sweden)

    Mircea Udrescu


    Full Text Available Marketing is a major factor to boost the competitiveness of the firm in an environment which is more and more turbulent. It centers the company’s management as being the ideal satisfaction of the current and potential consumer. This is why, in our conception, the marketing’s management represents a subsystem of the company’s’ general management by which shall be administered to specific activities, and also designed to contour the company’s’ activity object. In this article, the intent is to highlight the fact that the benchmarketing has come loose from cultivating the traditional process to the innovative organizational culture product. In this paper, the authors consider benchmarketing as a process of qualitative organizational culture adaptation to market requirements, depending on the context, so as to ensure the improvement of the economic criteria of appreciation of the business lucrative activities. Based on direct observations concerning small firms, followed by analysis, comparison and synthesis, the authors suggest taking into consideration the theoretical and practical benchmarketings’ approach, as being the current strategy of acquiring and cultivating excellence, as initiation philosophy and business development.

  18. Zika Virus Infection: Current Concerns and Perspectives. (United States)

    Maharajan, Mari Kannan; Ranjan, Aruna; Chu, Jian Feng; Foo, Wei Lim; Chai, Zhi Xin; Lau, Eileen YinYien; Ye, Heuy Mien; Theam, Xi Jin; Lok, Yen Ling


    The Zika virus outbreaks highlight the growing importance need for a reliable, specific and rapid diagnostic device to detect Zika virus, as it is often recognized as a mild disease without being identified. Many Zika virus infection cases have been misdiagnosed or underreported because of the non-specific clinical presentation. The aim of this review was to provide a critical and comprehensive overview of the published peer-reviewed evidence related to clinical presentations, various diagnostic methods and modes of transmission of Zika virus infection, as well as potential therapeutic targets to combat microcephaly. Zika virus is mainly transmitted through bites from Aedes aegypti mosquito. It can also be transmitted through blood, perinatally and sexually. Pregnant women are advised to postpone or avoid travelling to areas where active Zika virus transmission is reported, as this infection is directly linked to foetal microcephaly. Due to the high prevalence of Guillain-Barre syndrome and microcephaly in the endemic area, it is vital to confirm the diagnosis of Zika virus. Zika virus infection had been declared as a public health emergency and of international concern by the World Health Organisation. Governments and agencies should play an important role in terms of investing time and resources to fundamentally understand this infection so that a vaccine can be developed besides raising awareness.

  19. Safety concerns in composite manufacturing and machining (United States)

    Asmatulu, Eylem; Alonayni, Abdullah; Alamir, Mohammed


    Because of the superior properties, composites have been used in many industrial applications, including aerospace, wind turbines, ships, cars, fishing rods, storage tanks, swimming pool panels, and baseball bats. Each application may require different combinations of reinforcements and matrices, which make the manufacturing safety even more challenging while working on these substances. In this study, safety issues in composite manufacturing and machining were investigated in detail, and latest developments were provided for workers. The materials most frequently used in composite manufacturing, such as matrix (polyester, vinylester, phenolic, epoxies, methyl ethyl ketone peroxide, benzoil peroxide, hardeners, and solvents), and reinforcement materials (carbon, glass and Kevlar fibers, honeycomb and foams) can be highly toxic to human body. These materials can also be very toxic to the environment when dumped out uncontrollably, creating major future health and environmental concerns. Throughout the manufacturing process, workers inhale vapors of the liquid matrix, hardeners and solvents / thinners, as well as reinforcement materials (chopped fibers and particles) in airborne. Milling, cutting and machining of the composites can further increase the toxic inhalations of airborne composite particles, resulting in major rashes, irritation, skin disorders, coughing, severe eye and lung injury and other serious illnesses. The major portions of these hazardous materials can be controlled using appropriate personal protective equipment for the chemicals and materials used in composite manufacturing and machining. This study provides best possible safety practices utilized in composite manufacturing facilities for workers, engineers and other participants.

  20. Advances in lactoferrin research concerning bovine mastitis. (United States)

    Shimazaki, Kei-Ichi; Kawai, Kazuhiro


    Lactoferrin is a multifunctional, iron-binding glycoprotein found in milk and other exocrine secretions. Lactoferrin in milk plays vital roles in the healthy development of newborn mammals, and is also an innate resistance factor involved in the prevention of mammary gland infection by microorganisms. Inflammation of the udder because of bacterial infection is referred to as mastitis. There have been many investigations into the relationships between lactoferrin and mastitis, which fall into several categories. The main categories are fluctuations in the lactoferrin concentration of milk, lactoferrin activity against mastitis pathogens, elucidation of the processes underlying the onset of mastitis, participation of lactoferrin in the immune system, and utilization of lactoferrin in mastitis treatment and prevention. This minireview describes lactoferrin research concerning bovine mastitis. In the 1970s, many researchers reported that the lactoferrin concentration fluctuates in milk from cows with mastitis. From the late 1980s, many studies clarified the infection-defense mechanism in the udder and the contribution of lactoferrin to the immune system. After the year 2000, the processes underlying the onset of mastitis were elucidated in vivo and in vitro, and lactoferrin was applied for the treatment and prevention of mastitis.

  1. Wireless Network Security Vulnerabilities and Concerns (United States)

    Mushtaq, Ahmad

    The dilemma of cyber communications insecurity has existed all the times since the beginning of the network communications. The problems and concerns of unauthorized access and hacking has existed form the time of introduction of world wide web communication and Internet's expansion for popular use in 1990s, and has remained till present time as one of the most important issues. The wireless network security is no exception. Serious and continuous efforts of investigation, research and development has been going on for the last several decades to achieve the goal of provision of 100 percent or full proof security for all the protocols of networking architectures including the wireless networking. Some very reliable and robust strategies have been developed and deployed which has made network communications more and more secure. However, the most desired goal of complete security has yet to see the light of the day. The latest Cyber War scenario, reported in the media of intrusion and hacking of each other's defense and secret agencies between the two super powers USA and China has further aggravated the situation. This sort of intrusion by hackers between other countries such as India and Pakistan, Israel and Middle East countries has also been going on and reported in the media frequently. The paper reviews and critically examines the strategies already in place, for wired network. Wireless Network Security and also suggests some directions and strategies for more robust aspects to be researched and deployed.

  2. Lawsuits concerning nuclear power generation in FRG

    International Nuclear Information System (INIS)

    Saito, Osamu


    The confirmation of the courts of justice is required for the permission of power stations. This proposition is not in the laws in FRG, but in view of the recent judicatory regulation, it seems to be the norm established experimentally. From the character of German nation, more than 40 specialists and the committees independent of administration take part in the procedure of administrative permission, but considering the temporary procedure, the processes of five classes of courts join in these. Based on the background of such situation, the author outlined the traditional practice in the legislation and administration in the field of nuclear power generation, then investigated into the decisions of Freiburg and Wuerzburg courts of administrative litigation in 1977 and the decision of the federal constitutional court in 1978. Confronting the same technology of light water reactors, the Freiburg court said that the device protecting from the burst of a pressure vessel is necessary, but the Wuerzburg court did not demand it. The confrontations similar to it were seen in the requirements for the utilization of radioactive substances and the final storage of them. The recent decision of the federal constitutional court is concerned with FBRs, and the court discussed the problem of ''residual risks''. The studies on the German decisions are useful for Japan.

  3. Colourism: a global adolescent health concern. (United States)

    Craddock, Nadia; Dlova, Ncoza; Diedrichs, Phillippa C


    Colourism, a form of prejudice and discrimination based solely upon skin colour, stands to jeopardize the physical health, wellbeing and life chances of adolescents of colour, globally. Research shows that adolescents can experience colourism at school and college, in the criminal justice system, at work and in the media they consume. It is therefore unsurprising that adolescents of colour often express a desire for lighter skin tones and/or are dissatisfied with their skin tone. Although research is scarce, some studies include older adolescents in their samples of skin-lightening product users. This is significant as the evidence is clear that the unmonitored use of skin-lightening products can be harmful to physical and psychological health, with evidence linking skin-lightening use to skin damage, kidney failure and depression. Although it is evident that colourism is central to the lives of adolescents of colour, more research is needed concerning the use of skin-lightening products among adolescents.

    In December, 1998, The Project Formulation meeting on application of Nuclear Techniques to address red tide (Harmful Algal Bloom concerns) was held in Manila Philippines. This is an IAEA/RCA project with the participation of Australia, China, Indonesia, Malaysia, Pakistan, The Philippines, Thailand and Vietnam. The main objectives of this project (RAS/8/076) included: - Conduct of segmentation studies to gain information on the natural histories of sediments and to correlated these with Red Tide occurrences. - Development of descriptive and predictive of the behaviour of Algal Bloom as affected by the interplay of the causative organism with the environment parameters in the water column and sediments. - Development and field testing of a rapid assay technique based on tritium - labeled saxitoxin for toxin determination. The first phase has been completed in 2002 and the second phase will be completed in 2004. In the two years of 2001 - 2002 Ted Tide occurred in very larger area in Vietnam, for example, in the coast of Binh Thuan Province with the density of 39.10 9 cells/litre. The Ministry of science - technology environment of Vietnam has support 5.000 USD each years for sediment and algal sampling in Cam Ranh Bay (Nha Trang, 11 o 45N and 10 o 15E) and Ha Long Bay in the North - East of Vietnam (21 o 15 and 107 o 3E) and in 2003 in Tuy Phong Bay (Binh Thuan province) (10 o 15N, 108 o 45E). Three sediment core has been taken from Cam Ranh Bay, Ha Long Bay and Tuy Phong Bay. The volume of sediment core is Φ = 8 cm and h = 60 cm. The algal samples have been collected by Bongo nets in Cam Ranh, Ha Long Bay and Tuy Phong Bay. (author)

  6. Polymyxins: Antimicrobial susceptibility concerns and therapeutic options

    Directory of Open Access Journals (Sweden)

    V Balaji


    Full Text Available The increasing prevalence of multidrug-resistant nosocomial pathogens such as Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae poses a great challenge to the treating physicians. The paucity of newer effective antimicrobials has led to renewed interest in the polymyxin group of drugs, as a last resort for treatment of gram-negative bacterial infections. There is a dearth of information on the pharmacological properties of colistin, leading to difficulties in selecting the right dose, dosing interval, and route of administration for treatment, especially in critically-ill patients. The increasing use of colistin over the last few years necessitates the need for accurate and reliable in vitro susceptibility testing methods. Development of heteroresistant strains as a result of colistin monotherapy is also a growing concern. There is a compelling need from the clinicians to provide options for probable and possible colistin combination therapy for multidrug-resistant bacterial infections in the ICU setting. Newer combination drug synergy determination tests are being developed and reported. There are no standardized recommendations from antimicrobial susceptibility testing reference agencies for the testing and interpretation of these drug combinations. Comparison and analysis of these reported methodologies may help to understand and assist the microbiologist to choose the best method that produces accurate results at the earliest. This will help clinicians to select the appropriate combination therapy. In this era of multidrug resistance it is important for the microbiology laboratory to be prepared, by default, to provide timely synergistic susceptibility results in addition to routine susceptibility, if warranted. Not as a favour or at request, but as a responsibility.

  7. Nuclear education and training: cause for concern?

    International Nuclear Information System (INIS)

    Yamagata, Hiroshi


    Nuclear power plants have played an important role in electricity generation in the OECD member countries, contributing an average 24% over the past few years. One major criterion for the success of this technology has always been the education and training of competent personnel in all sectors of nuclear development and application. The high level of competence and know-how reached must be maintained in the future. Qualified personnel is required for running existing plants, building new nuclear power plants - at present especially in Japan and Korea - and for all activities associated with supply and waste management, decommissioning, and for all applications of nuclear technology above and beyond energy generation. The number of university graduates in the OECD countries is decreasing alarmingly, among other reasons because of the diminished attractiveness of these courses as a consequence of the reduced number of nuclear engineering courses offered in curricula. A broad-based program of disseminating basic information in nuclear technology in university curricula is urgently required. In industry, internal advanced and in-career training measures and programs are offered to ensure broad-based qualification as well as specialization in nuclear subjects of the staff, as demands are rising and flexibility is required of all staff members. This development implies that governments in particular are called upon to ensure, by long-term planning, that nuclear competence is preserved in science and research, in industry and applications, as part of their areas of responsibility and competence.

  8. Aviation Safety Concerns for the Future (United States)

    Smith, Brian E.; Roelen, Alfred L. C.; den Hertog, Rudi


    The Future Aviation Safety Team (FAST) is a multidisciplinary international group of aviation professionals that was established to identify possible future aviation safety hazards. The principle was adopted that future hazards are undesirable consequences of changes, and a primary activity of FAST became identification and prioritization of possible future changes affecting aviation. Since 2004, FAST has been maintaining a catalogue of "Areas of Change" (AoC) that could potentially influence aviation safety. The horizon for such changes is between 5 to 20 years. In this context, changes must be understood as broadly as possible. An AoC is a description of the change, not an identification of the hazards that result from the change. An ex-post analysis of the AoCs identified in 2004 demonstrates that changes catalogued many years previous were directly implicated in the majority of fatal aviation accidents over the past ten years. This paper presents an overview of the current content of the AoC catalogue and a subsequent discussion of aviation safety concerns related to these possible changes. Interactions among these future changes may weaken critical functions that must be maintained to ensure safe operations. Safety assessments that do not appreciate or reflect the consequences of significant interaction complexity will not be fully informative and can lead to inappropriate trade-offs and increases in other risks. The FAST strongly encourages a system-wide approach to safety risk assessment across the global aviation system, not just within the domain for which future technologies or operational concepts are being considered. The FAST advocates the use of the "Areas of Change" concept, considering that several possible future phenomena may interact with a technology or operational concept under study producing unanticipated hazards.

  9. Research and Development Concerning Coalbed Natural Gas

    Energy Technology Data Exchange (ETDEWEB)

    William Ruckelshaus


    The Powder River Basin in northeastern Wyoming is one of the most active areas of coalbed natural gas (CBNG) development in the western United States. This resource provides clean energy but raises environmental concerns. Primary among these is the disposal of water that is co-produced with the gas during depressurization of the coal seam. Beginning with a few producing wells in Wyoming's Powder River Basin (PRB) in 1987, CBNG well numbers in this area increased to over 13,600 in 2004, with projected growth to 20,900 producing wells in the PRB by 2010. CBNG development is continuing apace since 2004, and CBNG is now being produced or evaluated in four other Wyoming coal basins in addition to the PRB, with roughly 3500-4000 new CBNG wells permitted statewide each year since 2004. This is clearly a very valuable source of clean fuel for the nation, and for Wyoming the economic benefits are substantial. For instance, in 2003 alone the total value of Wyoming CBNG production was about $1.5 billion, with tax and royalty income of about $90 million to counties, $140 million to the state, and $27 million to the federal government. In Wyoming, cumulative CBNG water production from 1987 through December 2004 was just over 380,000 acre-feet (2.9 billion barrels), while producing almost 1.5 trillion cubic feet (tcf) of CBNG gas statewide. Annual Wyoming CBNG water production in 2003 was 74,457 acre-feet (577 million barrels). Total production of CBNG water across all Wyoming coal fields could total roughly 7 million acre-feet (55.5 billion barrels), if all of the recoverable CBNG in the projected reserves of 31.7 tcf were produced over the coming decades. Pumping water from coals to produce CBNG has been designated a beneficial water use by the Wyoming State Engineer's Office (SEO), though recently the SEO has limited this beneficial use designation by requiring a certain gas/water production ratio. In the eastern part of the PRB where CBNG water is generally of good

  13. Multiple sclerosis severity and concern about falling: Physical, cognitive and psychological mediating factors. (United States)

    van Vliet, Rob; Hoang, Phu; Lord, Stephen; Gandevia, Simon; Delbaere, Kim


    Concern about falling can have devastating physical and psychological consequences in people with multiple sclerosis (MS). However, little is known about physical and cognitive determinants for increased concern about falling inthis group. To investigate direct and indirect relationships between MS severity and concern about falling using structural equation modelling (SEM). Two hundred and ten community-dwelling people (21-73 years) with MS Disease Steps 0-5 completed several physical, cognitive and psychological assessments. Concern about falling was assessed using the Falls Efficacy Scale-International. Concern about falling was significantly associated with MS Disease Step and also balance, muscle strength, disability, previous falls, and executive functioning. SEM revealed a strong direct path between MS Disease Step and concern about falling (r = 0.31, p concern about falling in people with MS and had an excellent goodness-of-fit. The relationship between MS severity and increased concern about falling was primarily mediated by reduced physical ability (especially if this resulted in disability and falls) and less so by executive functioning. This suggests people with MS have a realistic appraisal of their concern about falling.

     Warfarin and direct oral anticoagulants (DOACs) are used for the initial treatment and secondary prevention of venous thromboembolism (VTE), and have similar efficacy. Patient concerns and preferences are important considerations when selecting an anticoagulant, yet these are not well studied.  VTE patients ( n  = 519) were surveyed from online sources (, and National Blood Clot Alliance Facebook followers [ n  = 495]) and a haematology clinic in Vermont ( n  = 24).  Patients were 83% females and on average (±standard deviation [SD]) 45.7 ± 13.1 years; 65% self-reported warfarin as their initial VTE treatment and 35% a DOAC. Proportions reporting being extremely concerned about the following outcomes were as follows: recurrent VTE 33%, major bleeding 21%, moderate bleeding 16% and all-cause death 29%. When asked about oral anticoagulant characteristics, patients strongly preferred anticoagulants that are reversible (53%), and for which blood drug levels can be monitored (30%). Lower proportions agreed with statements that regular blood testing is inconvenient (18%), that they are comfortable using the newest drug versus an established drug (15%) and that it is difficult to change their diet to accommodate their anticoagulant (17%). In multivariable-adjusted models, patients tended to have had as their initial treatment, and to currently be taking, the oral anticoagulant option they personally preferred.  Patients held the greatest concern for recurrent VTE and mortality, regardless of which treatment they were prescribed. Potential weaknesses of warfarin (e.g., dietary restrictions, regular monitoring) were generally not considered onerous, while warfarin's advantages (e.g., ability to monitor) were viewed favourably.

  16. Food safety concerns of fast food consumers in urban Ghana. (United States)

    Omari, Rose; Frempong, Godfred


    In Ghana, out-of-home ready-to-eat foods including fast food generally have been associated with food safety problems. Notwithstanding, fast food production and consumption are increasing in Ghana and therefore this study sought to determine the food safety issues of importance to consumers and the extent to which they worry about them. First, through three focus group discussions on consumers' personal opinions about food safety issues, some emergent themes were obtained, which were used to construct an open-ended questionnaire administered face-to-face to 425 respondents systematically sampled from 20 fast food restaurants in Accra. Findings showed that most fast food consumers were concerned about food hazards such as pesticide residue in vegetables, excessive use of artificial flavour enhancers and colouring substances, bacterial contamination, migrated harmful substances from plastic packages, and general unhygienic conditions under which food is prepared and sold. Consumers also raised concerns about foodborne diseases such as cholera, typhoid, food poisoning, diarrhoea, bird flu and swine flu. The logistic regression model showed that being male increased the likelihood of worrying about general food safety issues and excessive use of flavour enhancers than in females while being youthful increased the likelihood of being worried about typhoid fever than in older consumers. These findings imply that consumers in urban Ghana are aware and concerned about current trends of food safety and foodborne disease challenges in the country. Therefore, efforts targeted at improving food safety and reducing incidences of foodborne diseases should not only focus on public awareness creation but should also design more comprehensive programmes to ensure the making of food safety rules and guidelines and enforcing compliance to facilitate availability and consumers' choice of safe foods.

  17. Concerns about cultural neurosciences: a critical analysis. (United States)

    Martínez Mateo, Marina; Cabanis, Maurice; Cruz de Echeverría Loebell, Nicole; Krach, Sören


    Ten years ago, neuroscientists began to study cultural phenomena by using functional MRI. Since then the number of publications in this field, termed cultural neuroscience (CN), has tremendously increased. In these studies, particular concepts of culture are implied, but rarely explicitly discussed. We argue that it is necessary to make these concepts a topic of debate in order to unravel the foundations of CN. From 40 fMRI studies we extracted two strands of reasoning: models investigating universal mechanisms for the formation of cultural groups and habits and, models assessing differences in characteristics among cultural groups. Both strands simplify culture as an inflexible set of traits and specificities. We question this rigid understanding of culture and highlight its hidden evaluative nature.

  19. Malaysia's contributions towards global climate change concerns

    International Nuclear Information System (INIS)

    Yuzlaini Mohd Yusop; Yvonne Lunsong; Norhayati Kamaruddin


    Concerns about Green House Gas (GHG) emissions and global climate change were voiced by the scientific community as far back as the International Geophysical year in 1957 when climate changes scenarios and impacts were analysed. More recently, the United Nations Framework Convention on climate change (UNFCCC) was adopted in 1992, renewing a global acknowledgement and commitment towards curbing GHG emissions. Little progress was made until the adoption of Kyoto Protocol in December 1997, over 5 years later. Basically, developed countries would not commit to strong measures if there were no global effort (i. e. corresponding efforts by developing countries) while developing countries are waiting for developed countries to show concrete results first. Since 1950, developed countries cumulatively produced more than 80% of worldwide GHG emissions. Between 1950 and 1990, North America alone contributed 40 billion tons of carbon while Western and Eastern Europe contributed 57 billion tons. Developing countries produced only 24 billion tons of carbon emissions during the same period. At present, per capita emission in developed countries are also about ten times higher than those of developing countries. This imbalance has caused most developing countries to adopt a wait till others do it stance and justifiably so. Nonetheless, curbing GHG emissions should be a larger community effort (which includes business and the public) and not just the efforts of Governments and officials. Thus, the deciding factors should make more business or economic sense. It is likely that business and the general public would listen and contribute positively if they are made aware of potential cost savings and international competitiveness to be derived from these efforts. During the current economic slowdown, especially in East Asia, it makes business sense to defer the capital investment in new electricity generating capacity and related energy supply infrastructure.

  20. Nuisance Odors: Is there a Concern - 12340

    Energy Technology Data Exchange (ETDEWEB)

    Brounstein, Robert A. [TerranearPMC, Los Alamos New Mexico 87544 (United States)


    Nuisance odors are generally thought of as just being annoying or unpleasant and not causing any physiological harm to our internal organs or other biologic systems. Yet during an excavation of buried animal remains, field workers experienced a multitude of symptoms that are associated with exposures to toxic materials. An examination of the decomposition process revealed that there is a potential off-gassing of a number of common, yet harmful chemicals including ammonia, mercaptans, hydrogen sulfide, butyric acid and phenol. In addition, other compounds, that have limited information such as established health data and occupational exposure limits, were also potential contaminants-of-concern. While a variety of monitoring and sampling techniques were used to assess worker exposures, all results indicated non-detectable airborne concentrations. Nevertheless, workers were experiencing such symptoms as nausea and headaches. As such, protective measures were necessary for field personnel to continue work while having confidence that the project was instituting sincere steps to ensure their health and safety. Researching the possible reasons for the causes of workers exhibiting adverse health effects from nuisance odors revealed that such exposures initiate electrochemical pathways, starting from the olfactory bulb to the brain, followed by a transfer of information to such biologic systems as the hypothalamus and pituitary gland. These systems, in turn, secrete hormones that cause a number of involuntary reactions; many of which are observed as typical adverse health effects, when in fact, they are merely reactions caused by the brain's memory; most likely created from previous experiences to unpleasant odors. The concern then focuses of how the Occupational Safety and Health community shall respond to such workplace exposures. Future work in this area may need to focus on the viability of current occupational exposure limits and the possibility of revising these

    Scientific and technical development is primarily meant to improve the quality of life and to reduce mortality. The increased risk thus caused for the individual leads to a longer life expectation of man and to the ethical question of choosing the safety of a technical system. One must critically choose between justifiable effort and risk. Experience in reactor engineering (technical systems with hypothetical extreme risks) leads to considerations of the analysis to determine the risk of large chemical plants for inhabited neighbourhoods and attempts to design a conceptive and computer model for a safety analysis which can be of use in decisions regarding new planning.

  2. Understanding the interplay of cancer patients' instrumental concerns and emotions. (United States)

    Brandes, Kim; van der Goot, Margot J; Smit, Edith G; van Weert, Julia C M; Linn, Annemiek J


    1) to assess patients' descriptions of concerns, and 2) to inform a conceptual framework in which the impact of the nature of concerns on doctor-patient communication is specified. Six focus groups were conducted with 39 cancer patients and survivors. In these focus groups participants were asked to describe their concerns during and after their illness. Concerns were described as instrumental concerns (e.g., receiving insufficient information) and emotions (e.g., sadness). Patients frequently explained their concerns as an interplay of instrumental concerns and emotions. Examples of the interplay were "receiving incorrect information" and "frustration", and "difficulties with searching, finding and judging of information" and "fear". Instrumental concerns need to be taken into account in the operationalization of concerns in research. Based on the interplay, the conceptual framework suggests that patients can express instrumental concerns as emotions and emotions as instrumental concerns. Consequently, providers can respond with instrumental and emotional communication when patients express an interplay of concerns. The results of this study can be used to support providers in recognizing concerns that are expressed by patients in consultations. Copyright © 2017 Elsevier B.V. All rights reserved.

  3. Behavioural controversy concerning homo economicus: a Humean perspective

    Khandakar Elahi


    Full Text Available In his monumental masterpiece, A Treatise on Human Nature, which explains the methodology of human reasoning concerning matters of fact and describes the roles that passions and morals play in it, Hume arrives at an enormously interesting maxim: An academic controversy cannot continue for long unless the disputants assign different meanings to the major terms employed in the debate. This theory has been applied in this paper to examine the behavioural criticisms about Homo Economicus (HE, the pivotal perception in the neoclassical microeconomic model.To achieve this objective, the paper discusses the origin and evolution of the concept, reviews behavioural criticisms, summarises the main tenets of Hume’s philosophy of human knowledge and finally examines the behavioural opinions from Hume’s perspective. The paper concludes that Hume’s theory convincingly explains the reason why the HE controversy is continuing for over half century- a fact that both the mainstream and behavioural economists are ignoring.

    This paper presents the application of AI tools for the on-line identification of load structure in distribution networks. The authors have considered Artificial Neural Networks (ANN) which are known as valuable and fast tools for pattern identification or completion. This approach to the load model allows a more detailed analysis directed towards the optimization of system structure and working conditions. Traditional methods produce good results but raise the processing time problem, especially when applied to large systems. For such cases another approach appeal to the Genetic Algorithms, which are frequently referenced in the literature concerned with PDS (reconfiguration of open loop radial networks, optimal var-sources distribution, optimal selection of transformer tap position).

  5. Development of an international BRC [Below Regulatory Concern] limit

    International Nuclear Information System (INIS)

    Kennedy, W.E. Jr.


    The International Atomic Energy Agency (IAEA) has recently investigated the exemption from regulatory control of radiation sources containing limited quantities of radioactive materials. Early efforts were entitled de minimis and were aimed at establishing a philosophical basis and radiation dose limits. The main objectives of more recent work on exemption are to illustrate a method for developing practical radiological criteria, to establish generic criteria, and to determine the practicability of the preliminary exemption principles. The method used to develop the criteria relies on models to evaluate the potential radiation exposure pathways and scenarios for individuals and population groups potentially present following the unrestricted release of materials. This paper describes the assessment methods, presents the generic results expressed in terms of the limiting concentrations of selected radionuclides in municipal waste, and provides a comparison with recent regulatory efforts in the United States for considering selected wastes being Below Regulatory Concern (BRC). 17 refs., 4 tabs

  6. Social, Psychological and Health Concerns of People Living with HIV/AIDS in Mysore District, Karnataka. (United States)

    Sebastian, Shibu Thomas; Siddanna, Sunitha


    One of the significant health and social problem the world facing today is Acquired immune deficiency syndrome (AiDS). The patients affected with HIV and their family may face various psychosocial problems during diagnosis and treatment due to the stigma associated with this disease. The objective of the study was to identify social, psychological and health concerns of people living with HIV/AIDS (PLWHA) and its association with the demographic factors in Mysore District, Karnataka, India. A questionnaire based study was conducted among 194 participants in Mysore District, Karnataka state who were receiving care and support services. A 22-item questionnaire provided information regarding social, psychological and health concerns of PLWHA in Mysore district. A general linear regression model was used for assessing the predictors of social, psychological and health concerns. The main social concern was that of "Fear of Losing a loved one" whereas the main psychological concern was "Too much worry", "No cure for AIDS" was the highly rated health concern. Males had more social, psychological and health concerns when compared to females but was not statistically significant. Employed people were having fewer psychological concerns when compared to unemployed people. Unemployed people were having fewer health concerns than employed people. For every unit increase in age there were fewer social and health concerns and both these findings were statistically significant. PLWHA in the present study reported that they were concerned about social, psychological and health issues in spite of the fact they were attending counseling. Health care workers, including those in public health sector should be educated about the importance of these factors that influence the health of the population they are caring for.

    Reese, Jennifer Barsky; Beach, Mary Catherine; Smith, Katherine Clegg; Bantug, Elissa T; Casale, Kristen E; Porter, Laura S; Bober, Sharon L; Tulsky, James A; Daly, Mary B; Lepore, Stephen J


    Breast cancer patients commonly experience sexual concerns, yet rarely discuss them with clinicians. The study examined patient and provider experiences and preferences related to communication about breast cancer-related sexual concerns with the goal of informing intervention development. Patient data (n = 28) were derived from focus groups and interviews with partnered and unpartnered women treated for breast cancer reporting sexual concerns. Provider data (n = 11) came from interviews with breast cancer oncologists and nurse practitioners. Patient and provider data were analyzed separately using the framework method of qualitative analysis. Findings revealed individual and institutional barriers to effective communication about sexual concerns and highlighted key communication facilitators (e.g., a positive patient-provider relationship, patient communication as a driver of provider communication, and vice versa). Patients expressed preferences for open, collaborative communication; providers expressed preferences for focused intervention targets (identifying concerns, offering resources/referrals) and convenient format. A model of effective communication of sexual concerns was developed to inform communication interventions. Findings suggest that to improve patient-provider communication about sexual concerns, knowledge and skills-based interventions that activate patients and that equip providers for effective discussions about sexual concerns are needed, as are institutional changes that could incentivize such discussions.

    Phillips, L Alison; Diefenbach, Michael A; Kronish, Ian M; Negron, Rennie M; Horowitz, Carol R


    Patients' medication-related concerns and necessity-beliefs predict adherence. Evaluation of the potentially complex interplay of these two dimensions has been limited because of methods that reduce them to a single dimension (difference scores). We use polynomial regression to assess the multidimensional effect of stroke-event survivors' medication-related concerns and necessity beliefs on their adherence to stroke-prevention medication. Survivors (n = 600) rated their concerns, necessity beliefs, and adherence to medication. Confirmatory and exploratory polynomial regression determined the best-fitting multidimensional model. As posited by the necessity-concerns framework (NCF), the greatest and lowest adherence was reported by those necessity weak concerns and strong concerns/weak Necessity-Beliefs, respectively. However, as could not be assessed using a difference-score model, patients with ambivalent beliefs were less adherent than those exhibiting indifference. Polynomial regression allows for assessment of the multidimensional nature of the NCF. Clinicians/Researchers should be aware that concerns and necessity dimensions are not polar opposites.

  12. The Necessity-Concerns-Framework: A Multidimensional Theory Benefits from Multidimensional Analysis (United States)

    Phillips, L. Alison; Diefenbach, Michael; Kronish, Ian M.; Negron, Rennie M.; Horowitz, Carol R.


    Background Patients’ medication-related concerns and necessity-beliefs predict adherence. Evaluation of the potentially complex interplay of these two dimensions has been limited because of methods that reduce them to a single dimension (difference scores). Purpose We use polynomial regression to assess the multidimensional effect of stroke-event survivors’ medication-related concerns and necessity-beliefs on their adherence to stroke-prevention medication. Methods Survivors (n=600) rated their concerns, necessity-beliefs, and adherence to medication. Confirmatory and exploratory polynomial regression determined the best-fitting multidimensional model. Results As posited by the Necessity-Concerns Framework (NCF), the greatest and lowest adherence was reported by those with strong necessity-beliefs/weak concerns and strong concerns/weak necessity-beliefs, respectively. However, as could not be assessed using a difference-score model, patients with ambivalent beliefs were less adherent than those exhibiting indifference. Conclusions Polynomial regression allows for assessment of the multidimensional nature of the NCF. Clinicians/Researchers should be aware that concerns and necessity dimensions are not polar opposites. PMID:24500078

  5. Carbon Emission Reduction with Regard to Retailer’s Fairness Concern and Subsidies

    Directory of Open Access Journals (Sweden)

    Linghong Zhang


    Full Text Available This paper considers the impact of consumer environmental awareness (CEA, retailer’s fairness concern, and government subsidies on the two echelon supply chain with one manufacturer and one retailer. The manufacturer produces green products with carbon emission reduction. The government provides two types of alternative subsidies: a fixed subsidy (referred to as an F-type subsidy or a discount subsidy (referred to as a D-type subsidy to encourage the manufacturer to produce a product with a high carbon emission reduction rate. We aim to provide optimal solutions to the manufacturer and the retailer with regard to the retailer’s fairness concern and government subsidies; thus we discuss four decision scenarios: the benchmark model without the fairness concern and subsidy, the model with the retailer’s fairness concern, the model with fairness concern and the F-type subsidy, and the model with fairness concern and the D-type subsidy. We provide explicit solutions and numerical examples of the optimal carbon emission reduction rate, wholesale price, and retail price. Our study has four main findings: firstly, high consumer environmental awareness will benefit both the manufacturer and the retailer in the above four scenarios; secondly, the fairness concern and subsidy have a counter effect on the optimal strategies (the subsidy could alleviate the negative influence caused by retailer’s fairness concern; thirdly, the government could subsidize the retailer when there is unfairness in the supply chain so that the manufacturer could produce a product with lower carbon emission; finally, using the subsidy related to the environmental quality will be more helpful for improving environment quality, especially when the government has a budget constraint.

  6. The economics of dentistry: a neglected concern. (United States)

    Shariati, Batoul; MacEntee, Michael I; Yazdizadeh, Maryam


    Demand for economic evaluations in health care is growing with expectations that they will help to develop regional and national policies on health and social programmes. We present here the scope, quality and content of systematic reviews and meta-analyses relating to the economics of dentistry published over the last 15 years. To review the quality and outcome of systematic reviews and meta-analyses relating to the economics of dental treatments, preventions and services. A systematic search was conducted in 14 electronic databases for systematic reviews and meta-analyses published between January 1997 and July 2011 on the economics of oral disorders and oral health care. Review papers were extracted by two independent investigators to identify the characteristics, results and quality of the reviews and to highlight gaps in knowledge about the economics of dentistry. From 3150 unique references, we found 73 systematic reviews or meta-analyses of dental economics as primary or secondary outcomes. The focus of 12 of them was on the cost or cost-effectiveness of dental prevention, 54 on treatment, five on prevention and treatment and two on delivery of dental services. However, only 12 of the systematic reviews drew conclusions from economic data, and four of them constructed an economic model from synthesized data. Overall, the quality was good in the 12 systematic reviews but poor in the original studies. There is very little helpful data published on the economics of dentistry. © 2013 John Wiley & Sons A/S.

    International Nuclear Information System (INIS)

    Fourmentraux, G.


    This presentation is a report of the studies carried out by the Work Group on Functioning Safety of Programmable Automatic Control Devices and by the Group for Prevention Studies (GEP) from the CEA. The objective of these groups is to evaluate the methods which could be used to estimate the functioning safety of control and instrumentation systems involved in the Important Elements for Safety (EIS) of the Basic Nuclear Installations (INB) of the CEA, and also to carry out a qualification of automatic control devices. Norms, protocols and tools for the evaluation are presented. The problem comprises two aspects: the evaluation of fault avoidance techniques and the evaluation of fault control techniques used during the conceiving. For the fault avoidance techniques, the quality assurance organization, the environment tests, and the software quality plans are considered. For the fault control techniques, the different available tools and fault injection models are analysed. The results of an analysis carried out with the DEF.I tool from the National Institute for Research and Safety (INRS) are reported. (J.S.). 23 refs

  8. Some open questions concerning biological growth

    Directory of Open Access Journals (Sweden)

    Escudero, Carlos


    Full Text Available We briefly review the properties of radially growing interfaces and their connection to biological growth. We focus on simplified models which result from the abstraction of only considering domain growth and not the interface curvature. Linear equations can be exactly solved and the phenomenology of growth can be inferred from the explicit solutions. Nonlinear equations pose interesting open questions that are summarized herein.

    En este trabajo revisamos brevemente las propiedades de las superficies que crecen de forma radial y su conexión con el crecimiento biológico. Nos vamos a concentrar en modelos simplificados que resultan de la abstracción de sólo considerar el crecimiento del dominio y no la curvatura de la interfaz. Las ecuaciones lineales se pueden resolver exactamente y la fenomenología del crecimiento puede ser inferida de las soluciones explítas. Las ecuaciones no lineales dan lugar a interesantes problemas abiertos que vamos a resumir aquí.

  9. Residual stress concerns in containment analysis

    International Nuclear Information System (INIS)

    Costantini, F.; Kulak, R. F.; Pfeiffer, P. A.


    The manufacturing of steel containment vessels starts with the forming of flat plates into curved plates. A steel containment structure is made by welding individual plates together to form the sections that make up the complex shaped vessels. The metal forming and welding process leaves residual stresses in the vessel walls. Generally, the effect of metal forming residual stresses can be reduced or virtually eliminated by thermally stress relieving the vesseL In large containment vessels this may not be practical and thus the residual stresses due to manufacturing may become important. The residual stresses could possibly tiect the response of the vessel to internal pressurization. When the level of residual stresses is significant it will affect the vessel's response, for instance the yielding pressure and possibly the failure pressure. The paper will address the effect of metal forming residual stresses on the response of a generic pressure vessel to internal pressurization. A scoping analysis investigated the effect of residual forming stresses on the response of an internally pressurized vessel. A simple model was developed to gain understanding of the mechanics of the problem. Residual stresses due to the welding process were not considered in this investigation

  10. Thresholds of Toxicological Concern - Setting a threshold for testing below which there is little concern. (United States)

    Hartung, Thomas


    Low dose, low risk; very low dose, no real risk. Setting a pragmatic threshold below which concerns become negligible is the purpose of thresholds of toxicological concern (TTC). The idea is that such threshold values do not need to be established for each and every chemical based on experimental data, but that by analyzing the distribution of lowest or no-effect doses of many chemicals, a TTC can be defined - typically using the 5th percentile of this distribution and lowering it by an uncertainty factor of, e.g., 100. In doing so, TTC aims to compare exposure information (dose) with a threshold below which any hazard manifestation is very unlikely to occur. The history and current developments of this concept are reviewed and the application of TTC for different regulated products and their hazards is discussed. TTC lends itself as a pragmatic filter to deprioritize testing needs whenever real-life exposures are much lower than levels where hazard manifestation would be expected, a situation that is called "negligible exposure" in the REACH legislation, though the TTC concept has not been fully incorporated in its implementation (yet). Other areas and regulations - especially in the food sector and for pharmaceutical impurities - are more proactive. Large, curated databases on toxic effects of chemicals provide us with the opportunity to set TTC for many hazards and substance classes and thus offer a precautionary second tier for risk assessments if hazard cannot be excluded. This allows focusing testing efforts better on relevant exposures to chemicals.

  11. Romanian concern for advanced fuels development

    International Nuclear Information System (INIS)

    Ohai, Dumitru


    The Institute for Nuclear Research (ICN), a subsidiary of Romanian Authority for Nuclear Activities, at Pitesti - Romania, has developed a preliminary design of a fuel bundle with 43 elements named SEU 43 for high burnup in CANDU Reactor. A very high experience in nuclear fuels manufacturing and control has also been accumulated. Additionally, on the nuclear site Pitesti there is the Nuclear Fuel Plant (NFP) qualified to manufacturing CANDU 6 type fuel, the main fuel supplier for NPP Cernavoda. A very good collaboration of ICN with NFP can lead to a low cost upgrading the facilities which ensure at present the CANDU standard fuel fabrication to be able of manufacturing also SEU 43 fuel for extended burnup. The financial founds are allocated by Romanian Authority for Nuclear Activities of the Ministry of Industry and Resources to sustain the departmental R and D program 'Nuclear Fuel'. This Program has the main objective to establish a technology for manufacturing a new CANDU fuel type destined for extended burnup. It is studied the possibility to use the Recovered Uranium (RU) resulted from LWR spent fuel reprocessing facility existing in stockpiles. The International Agency for Atomic Energy (IAEA) sustains also this program. By ROM/4/025/ Model Project, IAEA helps ICN to solve the problems regarding materials (RU, Zircaloy 4 tubes) purchasing, devices' upgrading and personnel training. The paper presents the main actions needing to be create the technical base for SEU 43 fuel bundle manufacturing. First step, the technological experiments and experimental fuel element manufacturing, will be accomplished in ICN installations. Second step, the industrial scale, need thorough studies for each installation from NFP to determine tools and technology modification imposed by the new CANDU fuel bundle manufacturing. All modifications must be done such as to the NFP, standard CANDU and SEU fuel bundles to be manufactured alternatively. (author)

  12. On a conjecture concerning helly circle graphs

    Directory of Open Access Journals (Sweden)

    Durán Guillermo


    Full Text Available We say that G is an e-circle graph if there is a bijection between its vertices and straight lines on the cartesian plane such that two vertices are adjacent in G if and only if the corresponding lines intersect inside the circle of radius one. This definition suggests a method for deciding whether a given graph G is an e-circle graph, by constructing a convenient system S of equations and inequations which represents the structure of G, in such a way that G is an e-circle graph if and only if S has a solution. In fact, e-circle graphs are exactly the circle graphs (intersection graphs of chords in a circle, and thus this method provides an analytic way for recognizing circle graphs. A graph G is a Helly circle graph if G is a circle graph and there exists a model of G by chords such that every three pairwise intersecting chords intersect at the same point. A conjecture by Durán (2000 states that G is a Helly circle graph if and only if G is a circle graph and contains no induced diamonds (a diamond is a graph formed by four vertices and five edges. Many unsuccessful efforts - mainly based on combinatorial and geometrical approaches - have been done in order to validate this conjecture. In this work, we utilize the ideas behind the definition of e-circle graphs and restate this conjecture in terms of an equivalence between two systems of equations and inequations, providing a new, analytic tool to deal with it.

  13. Patients' and parents' concerns and decisions about orthodontic treatment. (United States)

    Kazancı, Fatih; Aydoğan, Cihan; Alkan, Özer


    Patients' and parents' expectations are important in orthodontic treatment decision making. The literature generally demonstrates the perceived benefits of orthodontic treatment, but patients' and their parents' concerns about orthodontic treatment have not been investigated comprehensively. The aim of this study was to identify patients' and parents' concerns about orthodontic treatment and compare them according to sex, age, and treatment demand level. One hundred and eighty-nine children and their parents were interviewed about concerns related to orthodontic treatment. Patients and parents were asked about orthodontic treatment decisions. Answers were recorded as "yes," "no," or "don't know." Chi-squared and Fisher's exact tests were used to compare concerns between age groups, sexes, and treatment demand levels. Kappa statistics were used to assess agreement between patients and their parents. Concerns about orthodontic treatment were gathered under 10 items as follows: "feeling pain," "the appearance of braces," "being teased," "avoiding smiling," "speech problems," "dietary changes," "problems with transportation," "economic problems," "long treatment duration," and "missing school." There was no statistically significant difference in concerns between the sexes or age groups. Some concern items and treatment demand were inversely related in patients. The results of this study demonstrate patients' and parents' concerns about orthodontic treatment. Differences between the concerns of patients with different treatment demands imply that children might reject orthodontic treatment because of their concerns. Appropriate consultation of patients addressing their concerns may help reduce anxiety and improve the acceptance of treatment.

  14. Inflow shortages in deregulated power markets - Reasons for concern?

    Bye, Torstein; Bruvoll, Annegrete; Aune, Finn Roar [Research Department, Statistics Norway, P.O. Box 8131 Dep., 0033 Oslo (Norway)


    In many countries hydropower constitutes a large share of the electricity producing capacity. In the earlier regulated electricity markets, production capacities exceeded demand due to security of supply concerns. The present deregulated markets base investments upon profitability alone, and security of supply issues are claimed to be less important. Market operators trust the pricing mechanism in competitive markets to clear. Then low inflow constitutes a less problem. Several markets, both under regulated and deregulated regimes, have faced serious droughts. Some of them have experienced problems with market clearance (Chile, Brazil, California) while other markets functioned well (The Nordic market). Important features to the market response are the flexibility of demand, the pattern of inflow shortage, the storage capacities, the possibility of trade between regions with different production technologies, and the market design and concentration. We apply an empirical based market model to simulate the effects under two inflow shortage scenarios in an international market with combined hydro and thermal capacities and restricted transmission capacities. We compare the scenarios with actual events and show that the model and the real market outcome are comparable. The simulations do not reveal any problems with the functioning of the market, which should calm down the anxiousness about security of supply in deregulated markets with stochastic energy supply.

  16. How does market concern derived from the Internet affect oil prices?

    International Nuclear Information System (INIS)

    Guo, Jian-Feng; Ji, Qiang


    Highlights: • The impact of market concern derived from the Web on oil volatility is analysed. • It has an equilibrium relationship between oil prices and long-run market concern. • The short-run market concerns have an asymmetric influence on oil price volatility. • The Internet can exaggerate the impact of information shocks on oil price. - Abstract: With the acceleration of oil marketisation and the rapid development of electronic information carriers, external information shocks can be easily and quickly transmitted to the oil market through the Internet. This paper analyses the impact of short- and long-run market concerns, derived from search query volumes in Google for different domains around the oil market on oil volatility using co-integration and the modified EGARCH model. Empirical results suggest there is a long-term equilibrium relationship between oil prices and long-run market concern for oil prices and oil demand. The short-run market concerns for the 2008 financial crisis and the Libyan war convulsion have a significant and asymmetric influence on oil price volatility. This indicates that market concern transmitted through the Internet can strengthen the linkage between oil price changes and external events by influencing the expectation of market traders, and to some extent it can exaggerate the impact of nonfundamental information shocks

  17. Prospective Study of Fertility Concerns and Preservation Strategies in Young Women With Breast Cancer (United States)

    Ruddy, Kathryn J.; Gelber, Shari I.; Tamimi, Rulla M.; Ginsburg, Elizabeth S.; Schapira, Lidia; Come, Steven E.; Borges, Virginia F.; Meyer, Meghan E.; Partridge, Ann H.


    Purpose Most research regarding fertility in young women with breast cancer has focused on long-term survivors. Little is known about how fertility concerns affect treatment decisions or fertility preservation strategies at the time of initial cancer diagnosis. Patients and Methods As part of an ongoing prospective multicenter cohort study, we surveyed women with newly diagnosed early-stage breast cancer at age ≤ 40 years. The baseline survey included sociodemographic, medical, and treatment data as well as a modified Fertility Issues Survey, including fertility concern and preservation items. Univariable and multivariable modeling were used to investigate predictors of greater fertility concern. Results Among the first 620 eligible respondents included in this analysis, median age was 37 years (range, 17 to 40 years); 425 women (68%) discussed fertility issues with their physicians before starting therapy, and 319 (51%) were concerned about becoming infertile after treatment. Because of concerns about fertility, four women (1%) chose not to receive chemotherapy, 12 (2%) chose one chemotherapy regimen over another, six (1%) considered not receiving endocrine therapy, 19 (3%) decided not to receive endocrine therapy, and 71 (11%) considered receiving endocrine therapy for < 5 years; 65 (10%) used fertility preservation strategies. Greater concern about fertility was associated with younger age, nonwhite race, not having children, and receipt of chemotherapy. Conclusion Many young women with newly diagnosed breast cancer have concerns about fertility, and for some, these substantially affect their treatment decisions. Only a minority of women currently pursue available fertility preservation strategies in this setting. PMID:24567428

    Full Text Available Audit report with modification of going concern indicates that in auditor’s opinion there is a risk that auditee could not survive. This going concern modification is not expected by companies because it would decrease public trust on the company’s image. This research aims to investigate the impact of financial condition, company growth, and auditor reputation on going concern audit opinion. The research object includes manufacturer listed on Indonesia Stock Exchange during 2008-2010 with 78 observations obtained using purposive sampling method. Data then is analyzed using logistic regression analysis. The result shows that the financial condition proxied by bankruptcy prediction model affect going concern auditor opinion negatively and significantly. While company size which is proxied by sales growth and auditor reputation which is proxied by audit firm size do not significantly affect the opinion.

  19. Coordinating Leader-Follower Supply Chain with Sustainable Green Technology Innovation on Their Fairness Concerns. (United States)

    Du, Bisheng; Liu, Qing; Li, Guiping


    Sustainable green technology innovation is essential in all the stages of the supply chain development. The members of the supply chain in each stage need to invest in sustainable green technology innovation research and development. However, whether the sustainable green technology innovation investments and profits for all the members are fairness concerned is a critical factor to motivate the supply chain members. Motivated by a real business investigation, in this study, a supply chain model with one supplier and one manufacturer is analyzed. We consider fairness concerns for the supplier and the manufacturer with sustainable green technology innovation development. We derive the optimal results in both with and without fairness concern. The results indicate that fairness concerns can promote and coordinate the supply chain members without advantage inequity averseness, to invest more on their sustainable green technology innovation development.

  20. Associations among Life Events, Empathic Concern, and Adolescents' Prosocial and Aggressive Behaviors Toward Specific Targets. (United States)

    Davis, Alexandra N; Luce, Haley; Davalos, Natasha


    The goal of the present study was to examine the links between life events and adolescents' social behaviors (prosocial and aggressive behaviors) toward specific targets and to examine how empathic concern may play a role in these associations. The study examined two hypotheses: both the mediating role of empathic concern and the moderating role of empathic concern. The sample included 311 high school students from the Midwest (M age = 16.10 years; age range = 14-19 years; 58.7% girls; 82.7% White, 13.6% Latino). The results demonstrated support for the moderation model as well as complex links between life events and prosocial and aggressive behaviors toward specific targets. The discussion focuses on the role of empathic concern in understanding how life events are ultimately associated with adolescents' social development.

  2. Drivers of going concern audit opinions: empirical evidence from Indonesia

    Directory of Open Access Journals (Sweden)

    Suroto Lina Rahmawati


    Full Text Available The study of the going concern audit opinions is an important component within the enhancement of firms’ responsibility and stewardship. A going concern audit opinions implies that the independent auditor doubt the future of the firm. This study aimed to examine the drivers of the likelihood of the going-concern audit opinions. Previous studies revealed that there were inconsistent drivers influencing the going-concern audit opinion. This study shows similar results to prior works. The result indicates that firms’ financial condition and profitability significantly affect the likelihood of the going-concern audit opinion, while firms’ size and leverage are not the determinants of the intensity of the going concern audit opinion.

  4. Concern About Petrochemical Health Risk Before and After a Refinery Explosion (United States)

    Cutchin, Malcolm P.; Martin, Kathryn Remmes; Owen, Steven V.; Goodwin, James S.


    On March 23, 2005, a large explosion at an oil refinery in Texas City, Texas caused 15 deaths and approximately 170 injuries. Little is known about how such an industrial accident influences concern about environmental health risks. We used measures of environmental health concern about nearby petrochemical production with a sample of Texas City residents to understand patterns of concern and change in concern after an industrial accident, as well as individual and contextual factors associated with those patterns. Survey interviews with residents of Texas City, Texas (N =315) both pre- and postexplosion using a brief Concern About Petrochemical Health Risk Scale (CAPHRS) and other questions were used to collect pertinent predictor information. CAPHRS baseline, postexplosion, and change scores were compared and modeled using ordinary least squares (OLS) regression and a mixed model. Higher preexplosion CAPHRS scores were predicted by younger adults, foreign-born Hispanics, non-Hispanic blacks, lower- and middle-income groups, and those who live with someone who has worked at the petrochemical plants. Higher CAPHRS change scores are predicted by the same variables (except income), as well as proximity to, or perception of, the explosion, and reports of neighborhood damage. Findings suggest these groups’ concern scores could indicate a greater vulnerability to psychological and physical harm generated by concern and stress arising from local petrochemical activities. A clearer understanding of concern about actual environmental health risks in exposed populations may enhance the evolving theory of stress and coping and eventually enable public health professionals to develop appropriate mitigation strategies.

  6. Do Online Privacy Concerns Predict Selfie Behavior among Adolescents, Young Adults and Adults? (United States)

    Dhir, Amandeep; Torsheim, Torbjørn; Pallesen, Ståle; Andreassen, Cecilie S.


    Selfies, or self-portraits, are often taken and shared on social media for online self-presentation reasons, which are considered essential for the psychosocial development and well-being of people in today’s culture. Despite the growing popularity and widespread sharing of selfies in the online space, little is known about how privacy concerns moderate selfie behavior. In addition to this, it is also not known whether privacy concerns across age and gender groups influence selfie behavior. To address this timely issue, a survey assessing common selfie behaviors, that is, frequency of taking (individual and group selfies), editing (cropping and filtering), and posting selfies online, and social media privacy concerns (over personal data being accessed and misused by third parties) was conducted. The web-survey was administered to 3,763 Norwegian social media users, ranging from 13 to 50 years, with a preponderance of women (n = 2,509, 66.7%). The present study investigated the impact of privacy concerns on selfie behaviors across gender and age groups (adolescent, young adult, and adult) by use of the structural equation modeling approach. The results suggest that young adults have greater privacy concerns compared to adolescents and adults. Females have greater privacy concerns than males. Greater privacy concerns among female social media users were linked to lower engagement in selfie behavior, but privacy concerns did not influence selfie behavior in the case of male adolescents and young adults. Overall, privacy concerns were more consistently and inversely related to selfie behavior (taking and posting) among females than males. The study results have theoretical as well as practical implications for both researchers and policy makers. PMID:28588530

There is currently a lack of evidence regarding the self-reported concerns of SCT patients before and after SCT.Aim and design: This exploratory study performed a secondary analysis of self-reported, written concerns of SCT patients before and after transplant to determine patients' concerns.Methods: Content analysis of text box entries of SCT patients collected between 2005 and 2007 at the Seattle Cancer Care Alliance. Text box entries were collected as part of symptom assessment using the Electronic Self-Report Assessment – Cancer instrument. The assessment was presented to 137 patients undergoing SCT at two time points: prior to ambulatory visits before any therapy had begun (T1 and at the first visit after hospital discharge following SCT (T2.Results: Text box entries were made before (n = 52 and after (n = 87 the transplant, resulting in 139 text box entries made by 137 patients representing 133 concerns. Using content analysis, the entries were categorized and ranked according to frequency. After symptom concerns, patients ranked work and financial issues the most frequent concerns prior to SCT. After SCT, symptoms remained the most frequently entered area of concern, followed by survival.Conclusion: Oncology providers need to assess SCT patients for work and financial concerns before and after transplant. Appropriate and timely referrals may ease the burden of these concerns for patients. Thus, assessment of financial and work concerns by the oncology team should be an integral part of quality health care for patients undergoing SCT.Keywords: self-report, electronic

  10. Fiscal 1999 survey report on basic feasibility concerning model project for energy conservation in fiber dyeing and processing industry in Thailand; 1999 nendo Tai ni okeru sen'i senshoku kako sangyo no sho energy ka model jigyo ni kakawaru kihonteki jisshi kanosei chosa hokokusho

    Energy Technology Data Exchange (ETDEWEB)



    A feasibility study was conducted for the implementation of the optimum model project in the fiber dyeing and processing industry in Thailand. This paper describes the results of fiscal 1999. Seventy percent of about 400 companies are those heavily consuming energy, while small-scale businesses having a production capacity of less than one million yards/month take the sixty percent of the industry. Their energy conserving measures are behind. Measures against ground subsidence and drainage cost these companies greatly. Trade competition with China and others is being intensified. Although designated under the Energy Saving Promotion Act, the plants are not enjoying the privilege. Needed for the energy saving measures are grasp of the current situation such as energy consumption status, thorough operation management, improvement of energy efficiency in the present production facilities, renewal/additional installation of production equipment, and implementation of developmental energy saving measures. As energy conservation measures are deemed adaptable to the industry if the investment recovery period is two years or less, diagnostic analysis was made on six plants, with diffusion of the result examined. The total energy consumption of the industry was estimated to be reducible by 35% through high-recovery-rate measures such as improvement of boilers, recovery of exhaust heat, control of energy consumption rate, and introduction of dyeing machines having low liquor ratio.

  11. Social Justice Attitudes and Concerns for Labor Standards

    Directory of Open Access Journals (Sweden)

    Michaela Schulz


    Full Text Available This study utilizes an adapted version of the Social Justice Scale to capture and assess the extent to which social-justice-related values and attitudes toward labor standards relate to consumer intentions and behaviors. This social cognitive model assesses, based on Ajzen’s theory of planned behavior, how “perceived behavior control” affects these behaviors either directly or indirectly through consumers’ intentions. It is hypothesized that individuals who value fairness and equity in social interactions are going to be more likely to engage with businesses that are known for ethical business practices and abstain from firms that are known to violate labor rights. The results confirm that consumers who are concerned with social justice are less likely to conduct business with enterprises that have the reputation of violating both human rights and labor rights. However, the results also reveal that consumers with low levels of “perceived behavioral control” justify their consumer behaviors as they do not think that they can make a difference.

    To assess the character and degree of concerns of glaucoma patients and identify demographic/clinical factors affecting the concerns. Prospective cross-sectional study. A questionnaire that addressed patients' concerns was administered to consecutive glaucoma patients. Severity of concern was scored with a scale of 0-5 in order of increasing severity. Age, sex, intraocular pressure, visual field (VF) mean deviation (MD), number of antiglaucoma medications, history of glaucoma surgery, and employment status were recorded. Questionnaire results of 152 patients (mean VF MD, -8.03 ± 7.86 dB [better eye] and -16.06 ± 10.22 dB [worse eye]; mean age, 69 ± 14 years) were analyzed. Severity of concern was greatest for general eyesight (2.92/5.00) and visual symptoms (2.78/5.00), followed by activities (2.20/5.00) and socioeconomic factors (2.13/5.00), and then ocular symptoms (1.69/5.00) (P factors correlated with VF MD of the better eye (r = -0.245; P = .003) and age (r = -0.260; P = .001). Glaucoma patients reported varied degrees of concern regarding items associated with quality of life. Certain items may be more concerning than others. Severity of some concerns increased with more severe VF loss, prior glaucoma surgery, or younger age. Copyright © 2017 Elsevier Inc. All rights reserved.

  11. Can Health and Environmental Concerns Meet in Food Choices?

    Directory of Open Access Journals (Sweden)

    Alessia Cavaliere


    Full Text Available The objective of the study is to analyze if there is a relationship between health and environmental sustainability concerns in food choices. We used data of 300 Italian consumers collected through a vis-à-vis survey. We performed cross-tabulations and chi-square tests for a selected set of variables measuring both types of concerns, segmenting the sample by age, gender and education. Our results suggest that the association between health and environmental concerns is often statistically significant, though we observe a high variable specificity of the associations. Socio-demographic conditions seem to play a role in determining the association between the two concerns, with middle-aged and/or highly-educated respondents showing a stronger association between health and environmental concerns.

  12. E-books: nurse faculty use and concerns. (United States)

    Abell, Cathy H; Garrett-Wright, Dawn


    The purpose of this study was to identify nurse educators' stage of concern regarding e-books and examine relationships between stage of concern and demographic variables. The use of e-books is growing, and nursing faculty must be prepared to use this evolving technology. A descriptive design was used with a convenience sample of 50 nurse educators attending a professional conference. Data were collected using a demographic questionnaire and the Stages of Concern (SoC) questionnaire. Sixty-four percent of participants' first high stage was Stage 0 (awareness); 22 percent had a first high stage of Stage 1 (informational). Using ordinal regression, no statistical significance was noted with the highest Stage of Concern and age (p = .431) or experience as a nurse educator (p = .893). Findings indicate low usage, faculty concerns, and the need for ongoing education regarding e-books.

  13. Spreading disease: a controversy concerning the metaphysics of disease. (United States)

    D'Amico, R


    This article concerns the metaphysics of disease. Is disease a fixed feature of the world or a social value or preference? I argue that disease is not a value-laden concept and thus debates concerning it differ fundamentally from debates concerning health, harm, or suffering where evaluative judgements are central. I show how the so-called social constructionist view of disease has been motivated both by ethical concerns with medical practices and general theoretical doubts about scientific naturalism. If I can show that ethical concerns about medical treatment can be answered without adopting social constructionism, that leaves only the broader theoretical question of naturalism. I cannot completely answer those theoretical doubts, but I show that the theoretical motivation is less convincing when it is separated from the moral challenge often accompanying it. I conclude that a convincing defense of the non-naturalistic conception of disease is rarely attempted and proves more difficult and counter-intuitive than its proponents assume.

  14. Comparing human papillomavirus vaccine concerns on Twitter: a cross-sectional study of users in Australia, Canada and the UK. (United States)

    Shapiro, Gilla K; Surian, Didi; Dunn, Adam G; Perry, Ryan; Kelaher, Margaret


    Opposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK. Using a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter. The content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK. 16 789 Twitter users who posted 43 852 tweets about HPV vaccines. The proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users. Tweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to 'perceived barriers' being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns. The proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  15. Factors that contribute to the body image concern of female college students. (United States)

    Silva, Wanderson Roberto; Dias, Juliana Chioda Ribeiro; Maroco, João; Campos, Juliana Alvares Duarte Bonini


    To estimate the contribution of sociodemographic and labor variables and body mass index to body image concern. In order to estimate body image concern, the Body Shape Questionnaire (BSQ) and the Weight Concerns Scale (WCS) were applied. A confirmatory factor analysis of scales was carried out. The reason χ2 by degree of freedom ratio (χ2/df ), Comparative Fit Index (CFI), Normed Fit Index (NFI), and root mean square error of approximation (RMSEA) were used. Convergent validity was assessed through the average variance extracted and composed reliability and the internal consistency through standardized Cronbach's alpha coefficient (α). A structural model was developed, and the body image concern was the second-order main construct. The model appropriation was evaluated based on the goodness-of-fit indices. The z test was used to estimate the significance of trajectories (β) using a 5% significance level. Totally, 595 female college students participated in the study, with a mean age of 20.42 ± 2.44 years. The entire model, with the inclusion of all independent variables, showed unsatisfactory adjustment and was refined. The final model presented a satisfactory adjustment (χ2/df = 5.75; CFI = 0.87; NFI = 0.85; RMSEA = 0.09) with inclusion of medication use because of studies (β = 0.08; p = 0.04), academic performance (β = 0.09; p = 0.02), economic class (β = 0.08; p = 0.03), and body mass index (β = 0.44; p concern. Medication use due to studies, academic performance, economic class and body mass index significantly contribute to body image concern.

  16. Perspective taking and empathic concern in adolescence: gender differences in developmental changes. (United States)

    Van der Graaff, Jolien; Branje, Susan; De Wied, Minet; Hawk, Skyler; Van Lier, Pol; Meeus, Wim


    Empathy is an important social skill and is believed to play an essential role in moral development (Hoffman, 2000). In the present longitudinal study, the authors investigated adolescents' development of perspective taking and empathic concern from age 13 to 18 years (mean age at Wave 1 = 13 years, SD = 0.46) and examined its association with pubertal status. Adolescents (283 boys, 214 girls) reported for 6 consecutive years on their dispositional perspective taking and empathic concern and for 4 consecutive years on pubertal status. Latent growth curve modeling revealed gender differences in levels and developmental trends. Gender differences in perspective taking emerged during adolescence, with girls' increases being steeper than those of the boys. Girls also showed higher levels of empathic concern than did boys. Whereas girls' empathic concern remained stable across adolescence, boys showed a decrease from early to middle adolescence with a rebound to the initial level thereafter. Boys who were physically more mature also reported lower empathic concern than did their less physically developed peers. The current study supports theoretical notions that perspective taking develops during adolescence as a result of cognitive development. Moreover, the results suggest that pubertal maturation plays a role in boys' development of empathic concern. PsycINFO Database Record (c) 2014 APA, all rights reserved.

  17. Affluence and objective environmental conditions: Evidence of differences in environmental concern in metropolitan Brazil. (United States)

    Nawrotzki, Raphael J; Guedes, Gilvan; do Carmo, Roberto Luiz


    In an age of climate change, researchers need to form a deepened understanding of the determinants of environmental concern, particularly in countries of emerging economies. This paper provides a region-specific investigation of the impact of socio-economic status (SES) and objective environmental conditions on environmental concern in urban Brazil. We make use of data that were collected from personal interviews of individuals living in the metropolitan areas of Baixada Santista and Campinas, in the larger São Paulo area. Results from multilevel regression models indicate that wealthier households are more environmentally concerned, as suggested by affluence and post-materialist hypotheses. However, we also observe that increasing environmental concern correlates with a decline in objective environmental conditions. Interactions between objective environmental conditions and SES reveal some intriguing relationships: Among poorer individuals, a decline in environmental conditions increases environmental concern as suggested by the objective problems hypothesis, while for the wealthy, a decline in environmental conditions is associated with lower levels of environmental concern.

  3. An analysis of electronic health record-related patient safety concerns (United States)

    Meeks, Derek W; Smith, Michael W; Taylor, Lesley; Sittig, Dean F; Scott, Jean M; Singh, Hardeep


    Objective A recent Institute of Medicine report called for attention to safety issues related to electronic health records (EHRs). We analyzed EHR-related safety concerns reported within a large, integrated healthcare system. Methods The Informatics Patient Safety Office of the Veterans Health Administration (VA) maintains a non-punitive, voluntary reporting system to collect and investigate EHR-related safety concerns (ie, adverse events, potential events, and near misses). We analyzed completed investigations using an eight-dimension sociotechnical conceptual model that accounted for both technical and non-technical dimensions of safety. Using the framework analysis approach to qualitative data, we identified emergent and recurring safety concerns common to multiple reports. Results We extracted 100 consecutive, unique, closed investigations between August 2009 and May 2013 from 344 reported incidents. Seventy-four involved unsafe technology and 25 involved unsafe use of technology. A majority (70%) involved two or more model dimensions. Most often, non-technical dimensions such as workflow, policies, and personnel interacted in a complex fashion with technical dimensions such as software/hardware, content, and user interface to produce safety concerns. Most (94%) safety concerns related to either unmet data-display needs in the EHR (ie, displayed information available to the end user failed to reduce uncertainty or led to increased potential for patient harm), software upgrades or modifications, data transmission between components of the EHR, or ‘hidden dependencies’ within the EHR. Discussion EHR-related safety concerns involving both unsafe technology and unsafe use of technology persist long after ‘go-live’ and despite the sophisticated EHR infrastructure represented in our data source. Currently, few healthcare institutions have reporting and analysis capabilities similar to the VA. Conclusions Because EHR-related safety concerns have complex

  4. Acquiring Consumer Trust: Minimizing the GAP Between Environmental Concern and Environmental Consumption

    Directory of Open Access Journals (Sweden)

    Elias Frederico


    Full Text Available Environmental management has become an important managerial tool for creating conditions for greater competitiveness of organizations. A significant portion of the population considers environmental issues while consuming. However, despite the proposed relationship between environmental concern and consumption, some studies have identified a gap between declared environmental concern and consumer behavior. One possible explanation for this gap is the lack of trust in the ethics of retailers and the perception that environmental appealing offers would be only artifices of marketing. Thus, this paper aims to analyze the moderating effect of trust in the relationship between Environmental concern and environmental purchase intention. To operationalize the study, an online survey was conducted among 696 Brazilian consumers. The sample was characterized as non-probabilistic. Validated scales were used to measure the variables and data were analyzed using structural equation modeling. The results show that there is a significant relationship between environmental concern and environmental purchase intention, however, the low explanatory power of the model points to the gap between discourse and practice. By analyzing the trust of consumers as moderating variable, it is clear that, by increasing consumers’ trust, the gap between environmental concern and consumption is diminished.

  5. Synthesis of common management concerns associated with dam removal (United States)

    Tullos, Desiree D.; Collins, Mathias J.; Bellmore, J. Ryan; Bountry, Jennifer A.; Connolly, Patrick J.; Shafroth, Patrick B.; Wilcox, Andrew C.


    Managers make decisions regarding if and how to remove dams in spite of uncertainty surrounding physical and ecological responses, and stakeholders often raise concerns about certain negative effects, regardless of whether or not these concerns are warranted at a particular site. We used a dam-removal science database supplemented with other information sources to explore seven frequently-raised concerns, herein Common Management Concerns (CMCs). We investigate the occurrence of these concerns and the contributing biophysical controls. The CMCs addressed are: degree and rate of reservoir sediment erosion, excessive channel incision upstream of reservoirs, downstream sediment aggradation, elevated downstream turbidity, drawdown impacts on local water infrastructure, colonization of reservoir sediments by non-native plants, and expansion of invasive fish. Biophysical controls emerged for some of the concerns, providing managers with information to assess whether a given concern is likely to occur at a site. To fully assess CMC risk, managers should concurrently evaluate site conditions and identify the ecosystem or human uses that will be negatively affected if the biophysical phenomenon producing the CMC occurs. We show how many CMCs have one or more controls in common, facilitating the identification of multiple risks at a site, and demonstrate why CMC risks should be considered in the context of other factors like natural watershed variability and disturbance history.

    While concern and narcissism seem to be contradictory in nature, clinical evidence and theoretical writings on pathological forms of concern--tracing their origin to deficiencies in early relationships with primary caretakers--suggest that the actual relationship between these two characteristics might be much more complicated. We respond to a study aimed to add empirical data to the clinical and theoretical knowledge examined the relationships between self-object functions, types of narcissism and pathological concern. The findings of the study showed that pathological concern was positively associated with self-object needs and that this association was mediated by covert narcissism. Our discussion focuses on the developmental and psychodynamic sources of pathological concern, as well as its significance in the intrapersonal and interpersonal domains.

  7. Examining the Role of Psychological Inflexibility, Perspective Taking and Empathic Concern in Generalized Prejudice


    Levin, Michael E.; Luoma, Jason B.; Vilardaga, Roger; Lillis, Jason; Nobles, Richard; Hayes, Steven C.

  12. Correlates of dysmorphic concern in people seeking cosmetic enhancement (United States)

    Castle, David J.; Molton, Michael; Hoffman, Keturah; Preston, Neil J.; Phillips, Katharine A.


    Objective To determine the clinical correlates of dysmorphic concern in persons seeking cosmetic enhancement from cosmetic physicians. Method A questionnaire survey of 137 patients attending the practices of two cosmetic physicians. Results Four subjects (2.9%; 95% CI = 0.8%–7.3%) had a diagnosis of body dysmorphic disorder (BDD), but many more expressed overconcern with physical appearance (‘dysmorphic concern’). Dysmorphic concern accounted for a substantial amount of the variance for mood, social anxiety, and impairment in work and social functioning, while concerns related to how self or others perceive the putative flaw in appearance, impacted significantly on work and leisure activities, but did not apparently influence mood and social anxiety to any significant degree. Conclusions Dysmorphic concern is a broad dimensional construct that is related to both inter- and intrapsychic distress and disablement associated with people seeking cosmetic enhancement PMID:15209836

    We investigate how moral concerns about permit trading affect an endogenous pollution permit trading equilibrium, where governments choose non-cooperatively the amount of permits they allocate to domestic industries. Politicians may feel reluctant to allow permit trading and/or may prefer that abatement is undertaken domestically because of moral concerns. This will have an effect on the initial permit allocations, and, therefore, on global emissions. The impact on global emissions depends on the precise formulation of the moral concerns, but under reasonable assumptions, we show that global emissions may increase. Thus, doing what is perceived as good does not always yield the desired outcome. However, this can be offset by restrictions on permit trading when governments have moral concerns about this trade.

    Full Text Available Company's ability to survive is a fundamental uncertainty faced in the preparation and auditing financial statements. Provision of going-concern opinion on these financial statements the company is still being debated. Public Accountant Professional Standards in section 341 states that the auditor is responsible for evaluating whether there is a major doubt on the ability of entities in the continued survival of the appropriate period of time, not more than one year from the date of the financial statements being audited. This research analyzed the financial and non financial factors that affected the provision of going-concern opinion. This research used samples of 63 companies with 315 observations, taken from years 2005-2009. The logistic regression analysis showed that the company's financial condition variables, mitigating evidence, and disclosure significantly influence the acceptance of going-concern opinion. Enterprise risk was not significant at propensity of going-concern opinion.

  12. Dynamics of the public concern and risk communication program implementation. (United States)

    Zaryabova, Victoria; Israel, Michel


    The public concern about electromagnetic field (EMF) exposure varies due to different reasons. A part of them are connected with the better and higher quality of information that people receive from science, media, Internet, social networks, industry, but others are based on good communication programs performed by the responsible institutions, administration and persons. Especially, in Bulgaria, public concern follows interesting changes, some of them in correlation with the European processes of concern, but others following the economic and political processes in the country. Here, we analyze the dynamics of the public concern over the last 10 years. Our explanation of the decrease of the people's complaints against EMF exposure from base stations for mobile communication is as a result of our risk communication program that is in implementation for >10 years.

  8. Empathic Concern Is Part of a More General Communal Emotion

    Directory of Open Access Journals (Sweden)

    Janis H. Zickfeld


    Full Text Available Seeing someone in need may evoke a particular kind of closeness that has been conceptualized as sympathy or empathic concern (which is distinct from other empathy constructs. In other contexts, when people suddenly feel close to others, or observe others suddenly feeling closer to each other, this sudden closeness tends to evoke an emotion often labeled in vernacular English as being moved, touched, or heart-warming feelings. Recent theory and empirical work indicates that this is a distinct emotion; the construct is named kama muta. Is empathic concern for people in need simply an expression of the much broader tendency to respond with kama muta to all kinds of situations that afford closeness, such as reunions, kindness, and expressions of love? Across 16 studies sampling 2918 participants, we explored whether empathic concern is associated with kama muta. Meta-analyzing the association between ratings of state being moved and trait empathic concern revealed an effect size of, r(3631 = 0.35 [95% CI: 0.29, 0.41]. In addition, trait empathic concern was also associated with self-reports of the three sensations that have been shown to be reliably indicative of kama muta: weeping, chills, and bodily feelings of warmth. We conclude that empathic concern might actually be a part of the kama muta construct.

  10. General practitioners' knowledge and concern about electromagnetic fields. (United States)

    Berg-Beckhoff, Gabriele; Breckenkamp, Jürgen; Larsen, Pia Veldt; Kowall, Bernd


    Our aim is to explore general practitioners' (GPs') knowledge about EMF, and to assess whether different knowledge structures are related to the GPs' concern about EMF. Random samples were drawn from lists of GPs in Germany in 2008. Knowledge about EMF was assessed by seven items. A latent class analysis was conducted to identify latent structures in GPs' knowledge. Further, the GPs' concern about EMF health risk was measured using a score comprising six items. The association between GPs' concern about EMF and their knowledge was analysed using multiple linear regression. In total 435 (response rate 23.3%) GPs participated in the study. Four groups were identified by the latent class analysis: 43.1% of the GPs gave mainly correct answers; 23.7% of the GPs answered low frequency EMF questions correctly; 19.2% answered only the questions relating EMF with health risks, and 14.0% answered mostly "don't know". There was no association between GPs' latent knowledge classes or between the number of correct answers given by the GPs and their EMF concern, whereas the number of incorrect answers was associated with EMF concern. Greater EMF concern in subjects with more incorrect answers suggests paying particular attention to misconceptions regarding EMF in risk communication.

  11. Formation of modern theoretical regulations about organization concerning management development

    Directory of Open Access Journals (Sweden)

    Zhalinska I.V.


    Full Text Available The article deals with the scientific concepts about an organization as the entity of management concerning management development. The author studies the principal theoretical regulations about an organization within the most spread schools of management and context of development of other managerial concepts in particular, strategic management. It is found out that an organization and its development had not considered as the factor of an effective activity before. Researches paid their attention to single aspects of organization activity where the aspects allowed to increase economic efficiency. However, the objective complication of conditions of enterprises’ activities caused the necessity of scientific research of adequate models of functioning and development of organizations, which currently cannot be provided by traditional management concepts. Thus, theoretical and practical prerequisites arise for a separate scientific set of researches within the science of management such as the theory of an organization. The article describes the main classified approaches to the models of an organization. The paper researches the challenges in present management, and those ones, which have caused the crisis in modern management. It is singled out the following actual aspects of modern organizational processes as the all-round use of modern information and computer systems, the development of integration and in cooperation in management, the appearance of new management technologies, the use of new assessment criteria for organization activity, striving for organizational shifts and innovations. Due to the generalization of the study results, the authors single out such key aspects in the development of the science of management, as the crisis of traditional management influences upon practical activity of modern organizations; the achievements of traditional management schools are becoming necessary, but not determinant factors of organization

  12. Body image concern and selective attention to disgusting and non-self appearance-related stimuli. (United States)

    Onden-Lim, Melissa; Wu, Ray; Grisham, Jessica R


    Although selective attention to one's own appearance has been widely documented in studies of body dysmorphic disorder (BDD), little is known about attentional bias toward non-self appearance-related stimuli in BDD. Furthermore, despite reports of heightened experience of disgust in BDD, it is unknown whether these individuals differentially attend to disgusting stimuli and whether disgust is important in processing of unattractive stimuli. We used a dot probe procedure to investigate the relationship between dysmorphic concern, a defining feature of BDD, and selective attention to faces, attractive, unattractive and disgusting images in a female heterosexual student population (N=92). At the long stimulus presentation (1000 ms), dysmorphic concern was positively associated with attention to faces in general and attractive appearance-related images. In contrast, at the short stimulus presentation (200 ms), there was a positive association between dysmorphic concern and disgusting images. Implications for theoretical models of BDD are discussed.

  14. Clues to patients' explanations and concerns about their illnesses. A call for active listening. (United States)

    Lang, F; Floyd, M R; Beine, K L


    Most patients who experience illness symptoms develop an explanatory model. More frequently than physicians realize, these attributions involve serious and potentially life-threatening medical conditions. Only a minority of patients spontaneously disclose or "offer" their ideas, concerns, and expectations. Often patients suggest or imply their ideas through "clues." Active listening is a skill for recognizing and exploring patients' clues. Without this communication skill, patients' real concerns often go unrecognized by health care professionals. Qualitative techniques including videotape analysis, postinterviewing debriefing, and interpersonal process recall were used to identify types of clues. We propose a taxonomy of clues that includes (1) expression of feelings (especially concern or worry), (2) attempts to understand or explain symptoms, (3) speech clues that underscore particular concerns of the patient, (4) personal stories that link the patient with medical conditions or risks, and (5) behaviors suggestive of unresolved concerns or unmet expectations. This clue taxonomy will help physicians recognize patients' clues more readily and thereby improve their active listening skills. A deeper understanding of the true reasons for the visit should result in increased patient satisfaction and improved outcomes.

  15. Marine environmental contamination: public awareness, concern and perceived effectiveness in five European countries. (United States)

    Jacobs, Silke; Sioen, Isabelle; De Henauw, Stefaan; Rosseel, Yves; Calis, Tanja; Tediosi, Alice; Nadal, Martí; Marques, António; Verbeke, Wim


    Given the potential of Perceived Consumer Effectiveness (PCE) in shaping pro-environmental behavior, the relationships between PCE, awareness of causes of contaminants in the marine environment, and concern about marine environmental contamination were investigated using Structural Equation Modeling (SEM). PCE is the belief that an individual has in being able to make a difference when acting alone. A web-based survey was performed in one western European country (Belgium), one northern European country (Ireland) and three southern European countries (Italy, Portugal and Spain), resulting in a total sample size of 2824 participants. The analyses confirm that European citizens are concerned about marine environmental problems. Participants from the southern countries reported the highest concern. In addition, the study participants did not have a strong belief in themselves in being capable of making a difference in tackling marine environmental problems. However, a higher awareness, which was associated with a higher degree of concern, enhanced the belief that an individual can make a difference in tackling marine environmental problems, though only when a concrete action was proposed. Consequently, information campaigns focusing on pro-environmental behavior are recommended to raise public awareness about marine environmental problems and at the same time explicitly refer to concrete possible actions. The findings indicate that when only awareness and concern are raised without mentioning a concrete action, PCE might even decrease and render the communication effort ineffective.

  16. Concern about HIV and AIDS among older people in the slums of Nairobi, Kenya. (United States)

    Chepngeno-Langat, Gloria; Falkingham, Jane C; Madise, Nyovani J; Evandrou, Maria


    The article explores the way that social networks and personal experiences affect perceived HIV-related concerns among people aged 50 years or older living in a low resource neighborhood with high HIV prevalence in Nairobi, Kenya. Multiple logistic regression is used to model the association between the reporting of an HIV-related concern and individual-level characteristics, personal experiences, and social interaction. The main concerns regarding HIV reported by older people in the study included caring for orphaned children (65%), caring for people with AIDS (48%), and losing material and social support from adult children (36%). Interestingly, 38% of respondents voiced concerns about HIV infection among older people. Respondents who had been individually affected by HIV and AIDS, who were part of a wide social network, or who participated in community activities were frequently more likely to report a concern. The findings highlight the significance of the role of social interaction and social networks in the diffusion of information and knowledge. These findings have implications for HIV and AIDS policy and programs, highlighting the potential for social networks and community-level interventions to educate and increase awareness about HIV and AIDS among older people. Community leaders can make good peer educators and communication agents for HIV/AIDS campaigns. Additionally, the recognized high level of personal vulnerability to HIV infection among older people suggests the need for targeted sexual behavior change programs among this often neglected group. © 2012 Society for Risk Analysis.

    Hopia, Hanna; Lottes, Ilsa; Kanne, Mariël


    Healthcare professionals encounter ethical dilemmas and concerns in their practice. More research is needed to understand these ethical problems and to know how to educate professionals to respond to them. To describe ethical dilemmas and concerns at work from the perspectives of Finnish and Dutch healthcare professionals studying at the master's level. Exploratory, qualitative study that used the text of student online discussions of ethical dilemmas at work as data. Participants' online discussions were analyzed using inductive content analysis. The sample consisted of 49 students at master's level enrolled in professional ethics courses at universities in Finland and the Netherlands. Permission for conducting the study was granted from both universities of applied sciences. All students provided their informed consent for the use of their assignments as research data. Participants described 51 problematic work situations. Among these, 16 were found to be ethical dilemmas, and the remaining were work issues with an ethical concern and did not meet criteria of a dilemma. The most common problems resulted from concerns about quality care, safety of healthcare professionals, patients' rights, and working with too few staff and inadequate resources. The results indicated that participants were concerned about providing quality of care and raised numerous questions about how to provide it in challenging situations. The results show that it was difficult for students to differentiate ethical dilemmas from other ethical work concerns. Online discussions among healthcare providers give them an opportunity to relate ethical principles to real ethical dilemmas and problems in their work as well as to critically analyze ethical issues. We found that discussions with descriptions of ethical dilemmas and concerns by health professionals provide important information and recommendations not only for education and practice but also for health policy. © The Author(s) 2015.

  18. A concern-based method to prioritize spill response activities

    Lamarche, A.; Bart, H.


    The Shoreline Cleanup Assessment Team (SCAT) of the Emergencies Division of Environment Canada in the Ontario Region developed a computerized method to help rank segments of shoreline according to levels of concern in the event of an oil spill. The original SCAT approach was designed to allow survey teams to acquire information about the state of shoreline spills so that assessments of oilings would be comparable in time and space. The SCAT method, which allows several decision makers to obtain an unbiased evaluation of the oiling situation, has been recognized in both Canada and the United States as a method that ensures the consistency of data gathering and processing for prioritization purposes. The concern-based prioritization system was integrated within the computerized response tools used by the SCAT team using tools such as the Great Lakes Electronic Environmental Sensitivities Atlas (GLEESA), a geographic information system (GIS) of environmental data, and Shore Assess, a GIS based computerized system used to provide support during a response phase of a spill. It was noted that this method is considered to be a practical response tool designed around the principles of performance support and cybernetics to help decision makers set priorities. It is not designed for pre-impact assessment. Instead, it ensures that existing knowledge of the spill characteristics and environmental conditions are used in a consistent and logical method to prioritize contingency plans. The factors used to evaluate concern for oiling, shoreline type and land use were described. Factors for concern assessment of biological organisms include the status of organisms as being either endangered, threatened, vulnerable, special concern, or not at risk. Characteristics of the species, potential effect of the pollutant and potential effect from response activities are other factors for concern. The method evaluates the concern for every category using a simple algorithm which is

    Full Text Available The financial audit is called in to take the responsibilities on prevention of shocking events in the life of a company. Therefore we have to look into both of some concepts and the practice of financial audit so as to improve its performance and utility. On this purpose we assume some proposals to going concern concept and its practically use improvement. Thus, taking in account the actual statements of the IFAC documents (ISA 570 and the latest results on 'going concern research (A. Rosman 2011, Bihmani and Co. 2009, Geiger, Raghunandan and Rama 2005, N. Kuruppu and Co. 2002 we consider something more might be done to accurately clarify the concept and to meet the investors requirements regarding financial auditors responsibilities on the future of the audited companies. We are going to focus on subjects such as: which are the responsibilities of the financial audit and the management regarding the going concern, what kind of audit should be performed on the matter of a company future, which are the best methods to analyze the future going of a company, where the information should comes from and how compulsory a mission of audit on 'going concern' should be. Using a sample of a couple of listed companies filing for bankruptcy we reached a conclusion regarding the connection between going concern opinion and its real effects. The conclusion consists in the fact that there is not a compulsory connection between the going concern opinion and the decision for bankruptcy. On this basis and, as a result of studying the conclusions of the upper named authors, we assume the idea that a separate going concern audit mission should be conceived, organized and performed. In this sense the concept of going concept, itself, should be improved. In our opinion a new concept of going concern would have better practical results regarding both methodology of performing the assessment of an entity as going concern and the responsibility of financial auditors in

  20. Food colors: Existing and emerging food safety concerns. (United States)

    Oplatowska-Stachowiak, Michalina; Elliott, Christopher T


    Food colors are added to different types of commodities to increase their visual attractiveness or to compensate for natural color variations. The use of these additives is strictly regulated in the European Union, the United States, and many other countries worldwide. There is a growing concern about the safety of some commonly used legal food colorants and there is a trend to replace the synthetic forms with natural products. Additionally, a number of dyes with known or suspected genotoxic or carcinogenic properties have been shown to be added illegally to foods. Robust monitoring programs based on reliable detection methods are required to assure the food is free from harmful colors. The aim of this review is to present an up to date status of the various concerns arising from use of color additives in food. The most important food safety concerns in the field of food colors are lack of uniform regulation concerning legal food colors worldwide, possible link of artificial colors to hyperactive behavior, replacement of synthetic colors with natural ones, and the presence of harmful illegal dyes-both known but also new, emerging ones in food. The legal status of food color additives in the EU, United States, and worldwide is summarized. The reported negative health effects of both legal and illegal colors are presented. The European Rapid Alert System for Food and Feed notifications and US import alerts concerning food colors are analyzed and trends in fraudulent use of color additives identified. The detection methods for synthetic colors are also reviewed.
