    Metformin is a biguanide class of drug used for the treatment of diabetes mellitus. It is well known that serum protein-ligand binding interaction significantly influence the biodistribution of a drug. Current study was performed to characterize the binding mechanism of metformin with serum albumin. The binding interaction of the metformin with bovine serum albumin (BSA) was examined using UV-Vis absorption spectroscopy, fluorescence, circular dichroism, density functional theory and molecular docking studies. Absorption spectra and fluorescence emission spectra pointed out the weak binding of metformin with BSA as was apparent from the slight change in absorbance and fluorescence intensity of BSA in presence of metformin. Circular dichroism study implied the significant change in the conformation of BSA upon binding with metformin. Density functional theory calculations showed that metformin has non-planar geometry and has two energy states. The docking studies evidently signified that metformin could bind significantly to the three binding sites in BSA via hydrophobic, hydrogen bonding and electrostatic interactions. The data suggested the existence of non-covalent specific binding interaction in the complexation of metformin with BSA. The present study will certainly contribute to the development of metformin as a therapeutic molecule.

  2. Model conception concerning rewetting by flooding

    International Nuclear Information System (INIS)

    Thermohydraulics essentially influences the wetting temperature, which may be assumed for the flooding phase to be a function of pressure and subcooling of the fluid. A one-dimensional heat transfer model was shown to describe the phenomena in the pipe wall to be wetted in a sufficiently correct manner, if the dependence on fluid subcooling is considered for the wetting temperature. The influence of the parameters mass flow, subcooling of the flooding water, system pressure, heat production, channel cross-section, and steam content near the wetting front on the speed of the wetting front were shown.

    Crosscutting concerns such as logging,security,and transaction,are well supported in the programming level by aspect-oriented programming technologies.However,addressing these issues in the high-level architecture design still remains open.This paper presents a novel approach to supporting crosscutting concern modelling in the software architecture design of component-based systems.We introduce a new element named "Aspect"into our architecture description language,ABC/ADL,to clearly model the behavior of crosscutting concerns.Aspect is the first class entity as Component and Connector in ABC/ADL.ABC/ADL Connectors provide the weaving points where the component and aspect crosscut.This approach effectively enables "separation of concerns" in high-level architecture design,and facilitates black-box reuse of COTS components.

    Scenarios are important tools for long-term planning, and there is great interest in using integrated models in scenario studies. However, scenario definition and assessment are creative, as well as scientific, efforts. Using facilitated creative processes, we have worked with stakeholders to define regionally significant scenarios that encompass a broad range of hydroclimatic, socioeconomic, and institutional dimensions. The regional scenarios subsequently inform the definition of local scenarios that work with context-specific integrated models that, individually, can address only a subset of overall regional complexity. Based on concerns of stakeholders in the semi-arid US Southwest, we prioritized three dimensions that are especially important, yet highly uncertain, for long-term planning: hydroclimatic conditions (increased variability, persistent drought), development patterns (urban consolidation, distributed rural development), and the nature of public institutions (stressed, proactive). Linking across real-world decision contexts and integrated modeling efforts poses challenges of creatively connecting the conceptual models held by both the research and stakeholder communities.

    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.

    In recent years, protein science has been revolutionized by the discovery of intrinsically disordered proteins (IDPs). In contrast to the classical paradigm that a given protein sequence corresponds to a defined structure and an associated function, we now know that proteins can be functional in the absence of a stable three-dimensional structure. In many cases, disordered proteins or protein regions become structured, at least locally, upon interacting with their physiological partners. Many, sometimes conflicting, hypotheses have been put forward regarding the interaction mechanisms of IDPs and the potential advantages of disorder for protein-protein interactions. Whether disorder may increase, as proposed, e.g., in the “fly-casting” hypothesis, or decrease binding rates, increase or decrease binding specificity, or what role pre-formed structure might play in interactions involving IDPs (conformational selection vs. induced fit), are subjects of intense debate. Experimentally, these questions remain difficult to address. Here, we review experimental studies of binding mechanisms of IDPs using NMR spectroscopy and transient kinetic techniques, as well as the underlying theoretical concepts and numerical methods that can be applied to describe these interactions at the atomic level. The available literature suggests that the kinetic and thermodynamic parameters characterizing interactions involving IDPs can vary widely and that there may be no single common mechanism that can explain the different binding modes observed experimentally. Rather, disordered proteins appear to make combined use of features such as pre-formed structure and flexibility, depending on the individual system and the functional context.

  15. Evaluation of a sequential extraction process used for determining mercury binding mechanisms to coal combustion byproducts.

    Leaching of mercury from coal combustion byproducts is a concern because of the toxicity of mercury. Leachability of mercury can be assessed by using sequential extraction procedures. Sequential extraction procedures are commonly used to determine the speciation and mobility of trace metals in solid samples and are designed to differentiate among metals bound by different mechanisms and to different solid phases. This study evaluated the selectivity and effectiveness of a sequential extraction process used to determine mercury binding mechanisms to various materials. A six-step sequential extraction process was applied to laboratory-synthesized materials with known mercury concentrations and binding mechanisms. These materials were calcite, hematite, goethite, and titanium dioxide. Fly ash from a full-scale power plant was also investigated. The concentrations of mercury were measured using inductively coupled plasma (ICP) mass spectrometry, whereas the major elements were measured by ICP atomic emission spectrometry. The materials were characterized by X-ray powder diffraction and scanning electron microscopy with energy dispersive spectroscopy. The sequential extraction procedure provided information about the solid phases with which mercury was associated in the solid sample. The procedure effectively extracted mercury from the target phases. The procedure was generally selective in extracting mercury. However, some steps in the procedure extracted mercury from nontarget phases, and others resulted in mercury redistribution. Iron from hematite and goethite was only leached in the reducible and residual extraction steps. Some mercury associated with goethite was extracted in the ion exchangeable step, whereas mercury associated with hematite was extracted almost entirely in the residual step. Calcium in calcite and mercury associated with calcite were primarily removed in the acid-soluble extraction step. Titanium in titanium dioxide and mercury adsorbed onto

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

    International Nuclear Information System (INIS)

    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)

    A combination of spectral experiment and molecular modeling techniques has been used to characterize the binding mechanism between an active component 5-hydroxymethyl-furfural (5-HMF) of traditional Chinese medicine and human serum albumin (HSA) or bovine serum albumin (BSA). The interaction mechanism of 5-HMF binding with HSA/BSA is analyzed. Although the drug can bind with HSA/BSA to form stable complexes, there are some differences in the bond strength. The values of binding distances (r) are different and low, which indicated the occurrence of energy transfer. The drug had conformational effect on HSA/BSA, which resulted in different changes of hydrophobic environment of the binding domain in HSA/BSA. The 'phase diagram' of fluorescence revealed that the changes on the conformational pattern of proteins have been affected by drug conformed to the "all-or-none" pattern. The interactions between drug and protein influenced by Co(II) were also discussed. Its effects acting on 5-HMF-HSA/BSA interactions are different. The computational modeling method was used to study the interaction between 5-HMF and HSA/BSA. The results of molecular model studies revealed that the binding modes for drug-serum albumin systems are mainly hydrophobic interactions and hydrogen bonding. These results are in accordance with spectral results. The research results have given a better theoretical reference for the study of pharmacological mechanism of 5-hydroxymethyl-furfural.

    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. PMID:27414648

    A composite consisting of sulfur/dehydrogenated polyacrylonitrile is one of the most promising cathode materials for use in rechargeable lithium-sulfur batteries. However, the reported sulfur contents have been low, less than 50 wt%, which compromise the intrinsic high specific capacity and energy of elemental sulfur and hence decrease significantly the specific energy of the composite. To identify the potential to further increase the sulfur content, we elucidate the binding mechanism of sulfur and polyacrylonitrile in their composite. The heat treatment experiments at varying timespans with excess sulfur showed a constancy of sulfur content after a critical length of timespan, indicating the saturation of sulfur in the structure of dehydrogenated polyacrylonitrile. Based on molecular structure and size consideration, it is proposed that the binding involves the formation of an 8 membered ring of sulfur embedded between 4 heterocyclic rings of dehydrogenated polyacrylonitrile. From this model and experimental results, we show that there exists an upper limit of sulfur content in the sulfur/dehydrogenated polyacrylonitrile composite at 56 wt%.

    The main objective of the present study was to develop a valid and appropriate model to evaluate companies' efficiency and environmental performance, concerning health, safety, and environmental management system principles. The proposed model overcomes the shortcomings of the previous models developed in this area. This model has been designed on the basis of a mathematical method known as Data Envelopment Analysis (DEA). In order to differentiate high-performing companies from weak ones, one of DEA nonradial models named as enhanced Russell graph efficiency measure has been applied. Since some of the environmental performance indicators cannot be controlled by companies' managers, it was necessary to develop the model in a way that it could be applied when discretionary and/or nondiscretionary factors were involved. The model, then, has been modified on a real case that comprised 12 oil and gas general contractors. The results showed the relative efficiency, inefficiency sources, and the rank of contractors.

    Macrophage migration inhibitory factor (MIF) is a multi-functional protein that acts as a cytokine and as an enzyme. Recently, MIF was identified as a non-canonical ligand of G protein-coupled chemokine receptor CXCR2 with low nanomolar affinity in leukocyte arrest and chemotaxis, but the precise knowledge of the molecular determinants of the MIF-CXCR2 interface has remained unknown. Therefore, we employed homology modeling, protein-protein docking, molecular dynamics (MD) simulations, Molecular Mechanics/Generalized Born Surface Area (MM/GBSA) binding free energy calculations and MM/GBSA binding free energy decomposition to obtain insights into the molecular recognition of MIF with CXCR2. The predicted binding pattern of MIF-CXCR2 is in good agreement with the experimental data and sheds light on the functional role of important MIF-CXCR2 interface residues in association with binding and signaling. According to our predictions, the R11A/D44A double mutations of MIF exhibit a pronounced defect in the binding affinity of MIF to CXCR2, resulting in large conformational changes. The potential two-site binding model for the MIF-CXCR2 recognition was proposed: initialized primarily by the non-polar interactions including the van der Waals and hydrophobic interactions, the N-terminal region of CXCR2 contacts the N-like loop and β-sheet of MIF (site 1), and then the ECL2 and ECL3 regions of CXCR2 form strong interactions with the pseudo-(E)LR motif and C-terminus of MIF, which induces the molecular thermodynamic motion of TMs for signal transduction (site 2). This study will extend our understanding to the binding mechanisms of MIF to CXCR2 and provide useful information for the rational design of potent inhibitors selectively targeting the MIF-CXCR2 interactions.

    The ability of a forest gap model to simulate the effects of climate variability and extreme events depends on the temporal resolution of the weather data that are used and the internal processing of these data for growth, regeneration and mortality. The climatological driving forces of most current gap models are based on monthly means of weather data and their standard deviations, and long-term monthly means are used for calculating yearly aggregated response functions for ecological processes. In this study, the results of sensitivity analyses using the forest gap model FORSKA{sub -}P and involving climate data of different resolutions, from long-term monthly means to daily time series, including extreme events, are presented for the current climate and for a climate change scenario. The model was applied at two sites with differing soil conditions in the federal state of Brandenburg, Germany. The sensitivity of the model concerning climate variations and different climate input resolutions is analysed and evaluated. The climate variability used for the model investigations affected the behaviour of the model substantially. (orig.)

    2015-04-01

    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.

Also considered in this context are potential improvements that might be obtained by the additional use of a Monte Carlo ''quitting rule'', such as that defined by Woo (1991), to select the number of Monte Carlo sample runs to perform. By the Monte Carlo approach, each output-value sample (realization) is calculated as a function of a sample-value vector of stochastic realizations, each of which in turn corresponds to a value of a corresponding distributed input variable. Abstractions from the SZ model and the Biosphere model are both used as input to the TSPA model. Sets of stochastic realizations required for SZ and TSPA abstractions ''expensive'' to generate, so the practical issue addressed by a ''quitting rule'' is how to determine what number of realizations is ''enough'' for the purpose of characterizing sampling error in the Monte Carlo estimate obtained for a specified model output of concern. In the TSPA context, the model output of concern is generally considered the time evolution of the arithmetic mean value, an estimator of the expected value, of TSPA-generated annual dose D(t) to the defined receptor within 10,000 y after waste-repository closure. Recommendations below specifically address: (1) whether or not a Monte Carlo approach (such as one employing the Woo quitting rule) is an appropriate basis for undertaking SZ- or TSPA-related uncertainty analysis, and (2) what other method might be more appropriate. While the following discussion and recommendations

  16. Some subtleties concerning fluid flow and turbulence modeling in 4.-valve engines

    2011-01-01

    Full Text Available In this paper some results concerning the structure and evolution of fluid flow pattern during induction and compression in 4.- valve engines with tilted valves were presented. Results were obtained by dint of multidimensional modeling of non-reactive flows in arbitrary geometry with moving boundaries. During induction fluid flow pattern was characterized with organized tumble motion followed by small but clearly legible deterioration in the vicinity of BDC. During compression the fluid flow pattern is entirely three-dimensional and fully controlled by vortex motion located in the central part of the chamber. In order to annihilate negative effects of tumble deterioration and to enhance swirling motion one of the intake valves was deactivated. Some positive and negative effects of such attempt were elucidated. The effect of turbulence model alteration in the case of excessive macro flows was tackled as well. Namely, some results obtained with eddy-viscosity model i.e. standard k-ε model were compared with results obtained with k-ξ-f model of turbulence in domain of 4.-valve engine in-cylinder flow. Some interesting results emerged rendering impetus for further quest in the near future.

  17. Waterfowl populations of conservation concern: learning from diverse challenges, models, and conservation strategies

    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.

  18. Personality is of central concern to understand health: towards a theoretical model for health psychology.

    Science.gov (United States)

    Ferguson, Eamonn

    2013-05-01

    This paper sets out the case that personality traits are central to health psychology. To achieve this, three aims need to be addressed. First, it is necessary to show that personality influences a broad range of health outcomes and mechanisms. Second, the simple descriptive account of Aim 1 is not sufficient, and a theoretical specification needs to be developed to explain the personality-health link and allow for future hypothesis generation. Third, once Aims 1 and 2 are met, it is necessary to demonstrate the clinical utility of personality. In this review I make the case that all three Aims are met. I develop a theoretical framework to understand the links between personality and health drawing on current theorising in the biology, evolution, and neuroscience of personality. I identify traits (i.e., alexithymia, Type D, hypochondriasis, and empathy) that are of particular concern to health psychology and set these within evolutionary cost-benefit analysis. The literature is reviewed within a three-level hierarchical model (individual, group, and organisational) and it is argued that health psychology needs to move from its traditional focus on the individual level to engage group and organisational levels.

    1981-01-01

    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

    The increasing concern of the policy maker about eating behavior has focused on the spread of obesity and on the evidence of a consistent number of individuals dieting despite being underweight. As the latter behavior is often attributed to the social pressure to be thin, some governments have already taken actions to ban ultra-thin ideals and testimonials. Assuming that people are heterogeneous in their healthy weights, but are exposed to the same ideal body weight, this paper proposes a the...

    2014-05-01

    Full Text Available In this research we present a technique by using which, extended UML models can be converted to standard UML models so that existing MBT techniques can be applied directly on these models. Existing Model Based Testing (MBT Techniques cannot be directly applied to extended UML models due to the difference of modeling notation and new model elements. Verification of these models is also very important. Realizing and testing non functional requirements such as efficiency, portability and security, at model level strengthens the ability of model to turn down risk, cost and probability of system failure in cost effective way. Access control is most widely used technique for implementing security in software systems. Existing approaches for security modeling focus on representation of access control policies such as authentication, role based access control by introducing security oriented model elements through extension in Unified Modelling Language (UML. But doing so hinders the potential and application of MBT techniques to verify these models and test access control policies. In this research we introduce a technique secure State UML to formally design security models with secure UML and then transform it to UML state machine diagrams so that it can be tested, verified by existing MBT techniques. By applying proposed technique on case studies, we found the results that MBT techniques can be applied on resulting state machine diagrams and generated test paths have potential to identify the risks associated with security constraints violation.

    START domain proteins are conserved α/β helix-grip fold that play a role in the non-vesicular and intracellular transport of lipids and sterols. The mechanism and conformational changes permitting the entry of the ligand into their buried binding sites is not well understood. Moreover, their functions and the identification of cognate ligands is still an active area of research. Here, we report the solution structure of STARD6 and the characterization of its backbone dynamics on multiple time-scales through 15N spin-relaxation and amide exchange studies. We reveal for the first time the presence of concerted fluctuations in the Ω1 loop and the C-terminal helix on the microsecond-millisecond time-scale that allows for the opening of the binding site and ligand entry. We also report that STARD6 binds specifically testosterone. Our work represents a milestone for the study of ligand binding mechanism by other START domains and the elucidation of the biological function of STARD6. PMID:27340016

    Organic memory device having gold nanoparticle (Au NPs) has been introduced in the structure of metal-pentacene-insulator-silicon (MPIS) capacitor device, where the Au NPs layer was formed by a new bonding method. Biomolecule binding mechanism between streptavidin and biotin was used as a strong binding method for the formation of monolayered Au NPs on polymeric dielectric of poly vinyl alcohol (PVA). The self-assembled Au NPs was functioned to show storages of charge in the MPIS device. The binding by streptavidin and biotin was confirmed by AFM and UV-VIS. The UV-VIS absorption of the Au NPs was varied at 515 nm and 525 nm depending on the coating of streptavidin. The AFM image showed no formation of multi-stacked layers of the streptavidin-capped Au NPs on biotin-NHS layer. Capacitance-voltage (C-V) performance of the memory device was measured to investigate the charging effect from Au NPs. In addition, charge retention by the Au NPs storage was tested to show 10,000 s in the C-V curve.

    1993-06-22

    We have investigated the hormone- and DNA-binding mechanisms of the wild-type human estrogen receptor (hER) overproduced in insect cells using a baculovirus expression system. The recombinant hER was indistinguishable in size (67 kDa) and immunogenically from the native human estrogen receptor in MCF-7 breast carcinoma cells. The recombinant hER was purified to 70-80% homogeneity with a two-step procedure that included ammonium sulfate precipitation and oligonucleotide affinity chromatography using a unique Teflon affinity matrix. The recombinant hER bound estradiol with a positively cooperative mechanism. At hER concentrations in excess of 13 nM the Hill coefficient reached a maximal value of 1.6, whereas, at lower hER concentrations, the Hill coefficient approached 1.0, suggesting that the hER was dissociated to the monomeric species and site-site interactions were diminished. The hER specifically bound an estrogen responsive element (ERE) from chicken vitellogenin II gene as measured by the gel mobility assay, ethylation, and thymine interference footprinting. Specific interference patterns suggest a two-fold symmetry of the hER binding to the ERE with each monomer of the hER bound in the major groove of the DNA. These data indicate that the recombinant hER is valuable to define the biochemical and structural properties of the native estrogen receptor. PMID:8512933

    Full Text Available In  this  article,  I  will  focus  on  connections  between  media,  culture and society  in order to understand two prototypical Maori responses to the film. The two kinds of responses are captured in the following phrases: “The film should never have been made” and “That’s not fiction, that’s reality”. One of my objectives is to show how these particular Maori responses to this fiction-film are entangled with deep concerns about  ethnic  policies  and marginalization  in  general.  In  other  words,  the  film  is explored  as  a statement  about  Maori  –  Pakeha  inter-ethnic  relations  and ‘biculturalism’, which is the official term for the political  vision of the post-colonial nation. Subsequently, my analysis suggests insights from a deeper concern about the contexts  that  contribute  to  these  particular  Maori formulations  of  media-reality configurations, in addition to lessons of a more general character.

  12. Molecular Binding Mechanism of TtgR Repressor to Antibiotics and Antimicrobials.

    Directory of Open Access Journals (Sweden)

    Ana Maria Fernandez-Escamilla

    Full Text Available A disturbing phenomenon in contemporary medicine is the prevalence of multidrug-resistant pathogenic bacteria. Efflux pumps contribute strongly to this antimicrobial drug resistance, which leads to the subsequent failure of clinical treatments. The TtgR protein of Pseudomonas putida is a HTH-type transcriptional repressor that controls expression of the TtgABC efflux pump, which is the main contributor to resistance against several antimicrobials and toxic compounds in this microbe. One of the main strategies to modulate the bacterial resistance is the rational modification of the ligand binding target site. We report the design and characterization of four mutants-TtgRS77A, TtgRE78A, TtgRN110A and TtgRH114A - at the active ligand binding site. The biophysical characterization of the mutants, in the presence and in the absence of different antimicrobials, revealed that TtgRN110A is the variant with highest thermal stability, under any of the experimental conditions tested. EMSA experiments also showed a different dissociation pattern from the operator for TtgRN110A, in the presence of several antimicrobials, making it a key residue in the TtgR protein repression mechanism of the TtgABC efflux pump. We found that TtgRE78A stability is the most affected upon effector binding. We also probe that one mutation at the C-terminal half of helix-α4, TtgRS77A, provokes a severe protein structure distortion, demonstrating the important role of this residue in the overall protein structure and on the ligand binding site. The data provide new information and deepen the understanding of the TtgR-effector binding mechanism and consequently the TtgABC efflux pump regulation mechanism in Pseudomonas putida.

    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.

    2016-03-01

    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.

    Wang, J. S.; Yan, J. J.; Hu, S. H.; Yang, Y. S.

    2010-03-01

    The attempt of the author in this research is made to calculate a heat transfer coefficient (HTC) by combining the filmwise theory with the dropwise notion for ethanol-water mixtures condensation. A new model, including ethanol concentration, vapor pressure and velocity, is developed by introducing a characteristic coefficient to combine the two mentioned-above theories. Under different concentration, pressure and velocity, the calculation is in comparison with experiment. It turns out that the calculation value is in good agreement with the experimental result; the maximal error is within ±30.1%. In addition, the model is applied to calculate related experiment in other literature and the values obtained agree well with results in reference.

    Directory of Open Access Journals (Sweden)

    Mihaela Poienar

    2014-09-01

    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 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.

    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. PMID:26406884

The purpose of this research is to reveal the extent to which respondents acknowledge the influence of advertising in decision-making. It can be said that in order to protect society from the harmful effects of advertising, we can create a model with a series of measures that advertising is socially responsible and even beneficial for the society.

  6. Bridgman's concern

    International Nuclear Information System (INIS)

    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

    The ongoing plume debate appears to focus on upwellings characterized by large heads and smaller tails, that form from a deep or basal thermal boundary layer (BTBL), which are driven by temperature excesses in the range of 200° C. We use 3-D laboratory experiments to explore how upwellings might differ from this common plume description when BTBLs are influenced by subducted plates. An important aspect of the models is the representation of ridge chemical differentiation processes resulting in slabs with two distinct layers; a lighter, depleted upper mantle component (Harzburgite:H) and a heavier, iron-rich crustal component (Basalt/Eclogite:B/E). Laboratory experiments utilize a working fluid of glucose syrup with temperature dependent density and viscosity. Compositionally distinct mantle reservoirs are represented through isothermal density/viscosity contrasts controlled by water content. The ambient fluid (AF) is contained within a rectangular tank that is heated from below and cooled from above to produce background convection with a Rayleigh number of 10-5-10-6. Highly viscous, tabular slabs are produced by pouring compositionally distinct syrup from two slab reservoirs (B/E and H) into a mold which is chilled to -5° C. The viscous layered slab is emplaced at the fluid surface and subsequently sinks through, stalls and spreads within a BTBL roughly twice the slab thickness (1 cm). Results show that a wide variety in upwelling morphologies form when layered slabs reside within the BTBL and that plume heads/tails are largely dissimilar to those of the standard plume model. The manner in which the slab laminae vs. AF in the BTBL combine (or segregate) within upwellings depends on viscosity/density contrasts, how slabs collapse in the BTBL, and time. End-member regimes include: experiments dominated by a very light H-slab component with early, cold H-plumes and late, hot B/E-AF plumes and experiments where density differences between H, B/E and AF are small and

    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.

  9. Model calculations concerning rotation at high solar latitudes and the depth of the solar convection zone

    International Nuclear Information System (INIS)

    The author has previously carried out extensive nonlinear numerical simulations of convection in a rotating spherical shell, motivated by the problem of understanding the Sun's differential rotation. The polar vortex found in earlier calculations, but not observed on the Sun, disappears when shell depths as large as 40% of the radius are assumed. The equatorial acceleration is also enhanced, producing a closer fit to solar observations than previous calculations for depths of 20%. The reasons for the disappearance of the polar vortex are that in deeper layers the Reynolds stresses, which transport angular momentum toward the equator to form the equatorial acceleration, reach to higher latitudes, and the moment of inertia of the polar cap region is a smaller fraction of the total for the shell. Although the model used is for a stratified liquid (the Boussinesq approximation), we argue that deep layers are less likely to have a polar vortex than shallow ones in the compressible case too. This result favors a solar convection zone substantially deeper than previously inferred from stellar structure calculations applied to the Sun, but is consistent with recent inferences of a deep convection zone made from measurements of solar oscillations

    Most jurisdictions grant dental licensure to graduating students following successful completion of a clinical exam. Testing agencies, which are independent of dental schools, nevertheless conduct their exams at school facilities. Patient participation in these exams raises ethical concerns regarding such issues as unlicensed providers' performing irreversible procedures with minimal supervision and graduates' limited accessibility to provide follow-up treatment. To address these concerns, a collaborative effort between University at Buffalo School of Dental Medicine faculty and testing agency personnel was launched. The aims of this article are to describe the development and implementation of the resulting Buffalo Model, to highlight ethical advantages in its application, and to identify areas of improvement to be addressed in future iterations. With the Buffalo Model, modifications were made to the traditional exam format in order to integrate the exam into the school curriculum, enabling candidates to take it at various points during their fourth year. In addition, after calibration of school faculty members, 98.5% of cases verified by faculty were accepted by the Commission on Dental Competency Assessments for use in the exam. In two cases, restorative treatment completed during the exam did not meet the school's competency standard. This new approach ameliorates ethical concerns associated with clinical licensure exams because treatment is provided only to patients of record within a sequenced treatment plan and timely and appropriate treatment is provided to all patients. The results of this first year of implementation also suggest that calibrated faculty members will not show bias in the selection of lesions or competency evaluations of candidates. PMID:27251344

    Full Text Available We give in this paper a short review of some recent achievements within the framework of multiphase flow modeling. We focus first on a class of compressible two-phase flow models, detailing closure laws and their main properties. Next we briefly summarize some attempts to model two-phase flows in a porous region, and also a class of compressible three-phase flow models. Some of the main difficulties arising in the numerical simulation of solutions of these complex and highly non-linear systems of PDEs are then discussed, and we eventually show some numerical results when tackling two-phase flows with mass transfer. Nous présentons dans cet article quelques résultats récents concernant la modélisation et la simulation numérique des écoulements multiphasiques.

    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

    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.

    A meso-diaminopimelate dehydrogenase (DAPDH) from Clostridium tetani E88 (CtDAPDH) was found to have low activity toward the D-amino acids other than its native substrate. Site-directed mutagenesis similar to that carried out on the residues mutated by Vedha-Peters et al. resulted in a mutant enzyme with highly improved catalytic ability for the synthesis of D-amino acids. The crystal structures of the CtDAPDH mutant in apo form and in complex with meso-diaminopimelate (meso-DAP), D-leucine (D-leu), and 4-methyl-2-oxopentanoic acid (MOPA) were solved. meso-DAP was found in an area outside the catalytic cavity; this suggested a possible two-step substrate-binding mechanism for meso-DAP. D-leu and MOPA each bound both to Leu154 and to Gly155 in the open form of CtDAPDH, and structural analysis revealed the molecular basis for the expanded substrate specificity of the mutant meso-diaminopimelate dehydrogenases.

    2016-10-01

    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. PMID:27565363

    Synthetic tsunamis generated from source regions around the Pacific Basin are analyzed in terms of their relative impact on United States coastal locations.. The region of tsunami origin is as important as the expected magnitude and the predicted inundation for understanding tsunami hazard. The NOAA Center for Tsunami Research has developed high-resolution tsunami models capable of predicting tsunami arrival time and amplitude of waves at each location. These models have been used to conduct tsunami hazard assessments to assess maximum impact and tsunami inundation for use by local communities in education and evacuation map development. Hazard assessment studies conducted for Los Angeles, San Francisco, Crescent City, Hilo, and Apra Harbor are combined with results of tsunami forecast model development at each of seventy-five locations. Complete hazard assessment, identifies every possible tsunami variation from a pre-computed propagation database. Study results indicate that the Eastern Aleutian Islands and Alaska are the most likely regions to produce the largest impact on the West Coast of the United States, while the East Philippines and Mariana trench regions impact Apra Harbor, Guam. Hawaii appears to be impacted equally from South America, Alaska and the Kuril Islands.

  7. Interrelationships between densitometric, geometric, and mechanical properties of rat femora: inferences concerning mechanical regulation of bone modeling.

    1993-11-01

    A compensation for differences in bone material quality by bone geometric properties in femora from two different strains of rats was previously shown by us. A feedback mechanism controlling the mechanical properties of the integrated bones was then proposed, in accordance with Frost's mechanostat theory. Evidence of such a system is now offered by the finding of a negative correlation between the modeling-dependent cross-sectional architecture (moment of inertia) and the mineral-dependent stiffness (elastic modulus) of bone material in the femoral diaphyses of 45 normal Wistar rats of different sexes, ages, and sizes. The strength and stiffness of the integrated diaphyses were found to depend on both cross-sectional inertia and body weight, not on bone mineral density. These findings are interpreted as supporting the hypothesis that the architectural efficiency of diaphyseal cross-sectional design resulting from the spatial orientation of bone modeling during growth is optimized as a function of the body weight-dependent bone strain history, within the constraints imposed by bone stiffness. Results suggest a modulating role of biomass, related to the system set point determination, and explain the usually observed lack of a direct correlation between mineral density and strength or stiffness of long bones in studies of geometrically inhomogeneous populations.

    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.

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

    International Nuclear Information System (INIS)

    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.

    We select the per capita gross domestic product and rural residents’ per capita net income in Xinjiang as the indicator variables to measure economic growth and farmers’ income increase in Xinjiang, respectively. We establish the cointegration equation, the vector error correction (VEC) model, and use the impulse response function to conduct empirical analysis of the evolutive law concerning relationship between economic growth and farmers’ income increase in Xinjiang during the period 1978-2010. The results show that there is a cointegration relationship between economic growth in Xinjiang and farmers’ income increase; the former plays an important role in promoting the latter, following the evolutive law "first intensify, then abate, intensify again, and finally become stable". We put the following policy recommendations: providing preferential policies for farmers, scientifically and rationally guiding the transfer of rural labor; improving the function of agriculture, increasing the proportion of non-farm income; gradually bridging the widening income gap between urban and rural areas, coordinating urban and rural development.

The traditional way of independent spare parts allocation is expected to cause great errors when it is applied to the spare parts allocation with dependent failures concerned. This paper analyzes the relation between the spare parts support level of fault source parts and the failure rate of the dependent parts. Computing methods for expected backorder and support cost of various parts are put forward. Furthermore, an optimal allocation model for spare parts including its solution is proposed with cost as its object and within constraints of expected backorder quantity. Eventually, the rationality and the project applicability of this model are proved through a case study.

    trans-N-Caffeoyltyramine (TNC), which was isolated from the Cortex Lycii in our laboratory, is a phenolic amide compound with multiple pharmacological activities. The interaction between TNC and human serum albumin (HSA) was studied by Nuclear magnetic resonance (NMR) relaxation experiment, fluorescence spectroscopy, and docking simulation. NMR methodology is based on the analysis of selective and non-selective spin-lattice relaxation rate enhancements of TNC protons in the presence of the HSA. Result indicated that the interaction occurred between HSA and TNC, and changed the proton magnetic environment of TNC. Fluorescence spectroscopy confirmed that TNC displayed a strong capability to quench the fluorescence of HSA, and the acting forces for binding were hydrogen bonds and van der Waals forces. Furthermore, the circular dichroism, synchronous, and three-dimensional fluorescence spectra, which were employed to determine the conformation of protein, revealed that binding of TNC with HSA could induce conformational changes in HSA. In addition, the molecular modeling results exhibited that TNC mainly bonded to site I in sub-domain IIA of HSA. PMID:27131098

    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.

    The current study was carried out to investigate the binding mechanism of a potential flavonoid compound 5-hydroxy-3‧,4‧,7-trimethoxyflavone (HTMF) with bovine serum albumin (BSA) using ultraviolet-visible, fluorescence, circular dichroism (CD) spectral measurements along with molecular docking and molecular dynamics (MD) simulation. It was confirmed from fluorescence spectra that the intrinsic fluorescence of BSA was robustly quenched by HTMF through a static quenching mechanism. The number of binding sites (n) for HTMF binding on BSA was found to be about one. The thermodynamic parameters estimated from the van't Hoff plot specified that hydrophobic force was the predominant force in the HTMF-BSA complex and there also exist hydrogen bonds and electrostatic interactions. The effect of HTMF on the BSA conformation examined using CD studies revealed that there is a decrease in the helical content of BSA upon HTMF interaction. The results of molecular docking study shed light on the binding mode which exposed that HTMF bind within the hydrophobic pocket of the subdomain IIIA of BSA. The stability of HTMF-BSA complex with respect to free protein was analyzed from the molecular dynamic studies. The electronic structure analysis of HTMF was achieved by using density functional theory (DFT) calculations at B3LYP/6-31G** level to support its antioxidant role. The results of computational analysis are in good consistence with the experimental data and the present findings suggested that HTMF exhibits a good binding propensity to BSA protein which will be helpful for the drug design.

  16. Concerning ethical risk assessment

    International Nuclear Information System (INIS)

    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.

  17. Adolescent fertility: worldwide concerns.

    Senderowitz, J; Paxman, J M

    1985-04-01

    There is growing concern over the adverse health, social, economic, and demographic effects of adolescent fertility. Morbidity and mortality rates ar significantly higher for teenage mothers and their infants, and early initiation of childbearing generally means truncated education, lower future family income, and larger completed family size. Adolescent fertility rates, which largely reflect marriage patterns, range from 4/1000 in Mauritania; in sub-Saharan Africa, virtually all rates are over 100. In most countries, adolescent fertility rates are declining due to rising age at marriage, increased educational and economic opportunities for young women, changes in social customs, increased use of contraception, and access to abortion. However, even if fertility rates were to decline dramatically among adolescent women in developing countries, their sheer numbers imply that their fertility will have a major impact on world population growth in the years ahead. The number of women in the world ages 15-19 years is expected to increase from 245 million in 1985 to over 320 million in the years 2020; 82% of these women live in developing countries. As a result of more and earlier premarital sexual activity, fostered by the lengthening gap between puberty and marriage, diminished parental and social controls, and increasing peer and media pressure to be sexually active, abortion and out-of-wedlock childbearing are increasing among teenagers in many developed and rapidly urbanizing developing countries. Laws and policies regarding sex education in the schools and access to family planning services by adolescents can either inhibit or support efforts to reduce adolescent fertility. Since contraceptive use is often sporadic and ineffective among adolescents, family planning services are crucial. Such programs should aim to reduce adolescents' dependence on abortion through preventive measures and increase awareness of the benefits of delayed sexual activity. Similarly, sex

    Emmanouilides, Christos E; Karampola, Maria I; Beredima, Maria

    2016-08-01

    As patents of the first introduced biologic therapeutics in oncology have begun to expire, competing pharmaceutical companies are allowed to produce and market the same protein as the original agent. These products are called biosimilars. Upon patent expiration, biosimilars would hopefully be a cheaper alternative to the original agent and that is the main reason for their existence. Although the financial aspect is similar to generics, the complex nature of these products generates the need for a distinct regulatory environment. Biosimilars are produced by DNA technology in bacteria, plant cells, or animal cells, while generics are produced by chemical synthesis. Details in the process of synthesis, selection of the microorganism, protein extraction, purification and manufacturing, affect the precise nature of the end product. Monoclonal antibodies are large proteins with four polypeptide chains and interact variably with each other and with the environment. It is important for payors to realize that biosimilars are different from generics; therefore, they need to develop different set of rules for approving, registering, and dispensing biosimilars. Regulators ought to respect the physicians' request for non-interchangeability and facilitate in any possible way of traceability. Such regulations along with a rigorous pharmacovigilance program will satisfy the concerns for true equivalence in activity and long-term safety. This is the only way to accumulate over time reliable safety information for new biosimilars. In conclusion, the wish born by the medical community and the society for a more affordable health system triggers the emergence of biosimilars, which could meet that goal if properly regulated.

  19. Lead toxicity: Current concerns

    Energy Technology Data Exchange (ETDEWEB)

    1993-04-01

    Over the 20-year period since the first issue of Environmental Health Perspectives was published, there has been considerable progress in the understanding of the potential toxicity of exposure to lead. Many of these advances have been reviewed in published symposia, conferences, and review papers in EHP. This brief review identifies major advances as well as a number of current concerns that present opportunities for prevention and intervention strategies. The major scientific advance has been the demonstration that blood lead (PbB) levels of 10-15 micrograms/dL in newborn and very young infants result in cognitive and behavioral deficits. Further support for this observation is being obtained by prospective or longitudinal studies presently in progress. The mechanism(s) for the central nervous system effects of lead is unclear but involve lead interactions within calcium-mediated intracellular messenger systems and neurotransmission. Effects of low-level lead exposure on blood pressure, particularly in adult men, may be related to the effect of lead on calcium-mediated control of vascular smooth muscle contraction and on the renin-angiotensin system. Reproductive effects of lead have long been suspected, but low-level effects have not been well studied. Whether lead is a carcinogen or its association with renal adenocarcinoma is a consequence of cystic nephropathy is uncertain. Major risk factors for lead toxicity in children in the United States include nutrition, particularly deficiencies of essential metals, calcium, iron, and zinc, and housing and socioeconomic status. A goal for the year 2000 is to reduce prevalence of blood lead levels exceeding 15 micrograms/dL. 97 refs.

    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.

  3. 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

    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 Tc, OER, OERbgr 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 agr and bgr values corresponding to those of generic radiosensitive tumours. According to the model predictions, a whole tumour with shorter Tc 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 OERbgr 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.

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

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

    1997-08-01

    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)

    Full Text Available This study analyses the application of law enforcement model on juvenille offender before the law. Especially, in investigations according to Act number 11, 2012 about Juvenille Penal Court system in Central Java. Since the act has been formally implemented, the penal court elements have been given two years time to prepare strategies in handling juvenille offender through Diversion with Restorative Justice approach. However, the implementation of Diversion needs several infrastructures such as Juvenille Investigators, Diversion Standard of Operation (SOP, and a proper place for investigating children and mediation process, including children cells. This is an empirical study with primary and secondary sources, including analysis of Acts, literature review, and expert review. The data analysis will be done qualitatively.

    Borg, J.; Bibring, J.P.; Cowsik, G.; Langevin, Y.; Maurette, M.

    1983-02-15

    In this paper we present our most recent results on ion implantation and erosion effects, intended to reproduce the superficial amorphous layers of radiation damage observed with a high voltage electron microscope on ..mu..m-sized grains extracted from the lunar regolith and which result from the exposure of the grains to the solar wind. We next outline theoretical computations which yield the thickness distribution of such amorphous layers as a function of the exposure time of the grains at the surface of the moon, the He/H ratio, and the speed distribution in the solar wind. From this model, the position of the peak in the solar wind speed distribution is the major parameter controlling the thickness of the amorphous layer.

    矿产勘查融资模式与一国的地质工作体制和机制密切相关,具有一定的国别特征。整体来看,在矿业发达国家的勘查投融资体制中,融资模式可分为两种:一种是以加拿大、澳大利亚等新兴矿业市场为代表的市场主导、多种金融手段为辅的模式;另一种是以英美为代表的以证券融资为主导的模式。我国是以政府投入和社会投资为主的分散型模式。各国矿产勘查投融资政策启示:(1)健全的政策性融资体系与市场性融资良性互动;(2)分类设计勘探采矿类上市公司上市渠道,加强资本市场对矿业勘查阶段的支持;(3)鼓励发展中介融资机构,提高矿业勘查阶段的科学性;(4)吸引外商投资,提升矿产勘查投融资市场环境。%Mineral exploration ifnancing model is closely related to one country's geological work system and mechanism, which has a certain national characteristics. As a whole, there are two ifnancing models in the exploration investment and ifnancing system of developed mining countries. One is market-oriented ifrst, various monetary measures second, represented by emerging mining markets such as Canada and Australia; the other is dominated by securities ifnancing, with the United Kingdom and the USA as representations. While, in China, the investment and ifnancing model is the decentralized mode with government investment and social investment as the focus. On this basis, this paper introduces the enlightenments drawn from international mineral exploration investment and ifnancing policy. These include: the benign interactions between a sound policy ifnancing system and market ifnancing; classifying the channel of their listing for listed companies of exploration and mining; enhancing the support of capital market for mining exploration stage; encouraging the development of intermediary ifnancing institutions; raising the scientiifc nature of the mining exploration stage

    1979-09-01

    The current reasons for concern about the diesel engine for light-duty vehicles are explained, and an overview of the major issues impacting upon future diesel-related policy considerations is presented. Light-duty diesels are of immediate concern because proposed environmental legislation could impact upon their market future as early as model year 1981. The environmental issues affecting these vehicles also have implications for other categories of diesels (heavy-duty mobile and stationary application). Part I presents background and overview information on the reasons for the diesel's emergence as a major concern in the regulatory area and Part II summarizes the issues surrounding the diesel in three major areas: protecting health and the environment; fuel conservation; and broad economic and programmaic trade-offs arising from the previous two areas.

Let F be a family of meromorphic functions in the unit disc △, and a be a nonzero finite complex number. If for any f ∈ F, the zeros of f are of multiplicity, f and f' share a, then there exists a positive number M such that for any f ∈ F, (1 -|z|~2)(|f'(z)|)/(1+|f(z)|~2)≤ M.

  2. Researches with the 'Fertexpert' model concerning the relationships between the efficiency indexes of the fertilizers usage in optimal economic rates and the agrochemical indexes of the soil and expected yields

    International Nuclear Information System (INIS)

    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, Rs, 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, P2O5 or K2O), 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 Rs 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)

    2013-12-01

    The two-domain taurocyamine kinase (TK) from Paragonimus westermani was suggested to have a unique substrate binding mechanism. We performed site-directed mutagenesis on each domain of this TK and compared the kinetic parameters Km(Tc) and Vmax with that of the wild-type to determine putative amino acids involved in substrate recognition and binding. Replacement of Y84 on domain 1 and Y87 on domain 2 with R resulted in the loss of activity for the substrate taurocyamine. Y84E mutant has a dramatic decrease in affinity and activity for taurocyamine while Y87E has completely lost catalytic activity. Substituting H and I on the said positions also resulted in significant changes in activity. Mutation of the residues A59 on the GS region of domain 1 also caused significant decrease in affinity and activity while mutation on the equivalent position on domain 2 resulted in complete loss of activity.

  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

    Science.gov (United States)

    Rudowicz, C.

    2008-07-01

    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.

  6. Phytotoxins: environmental micropollutants of concern?

    Science.gov (United States)

    Bucheli, Thomas D

    2014-11-18

    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.

    The problems of uranium mining and milling are related to the huge amount of waste containing radioactive as well as chemical pollutants. Tailings can be satisfactorly protected so that the environmental impact is minor in the short term. The methods to reduce the risks are many. The actual releases today in the Sillamaee region of the Baltic Sea from the tailings pond are relatively small and should not give rise to concern. However, the situation is unstable, which is why efforts to find remediation methods are justified

    2002-06-01

    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.

It will also look into the Revised Guidelines of the ICMJE vis-à-vis issues related to industry-sponsored research. Journals And Editors In the last chapter, we saw how conflict of interest related to individuals and institutions are discussed and resolved by AAMC. Conflict of interest because of industry's increasing clout has also engaged the attention of editors of important journals and some significant editorials in this connection are worth a close study by all concerned researchers and institutions, for they reflect reasoned responses to disturbing developments. The titles themselves reflect their concern:Is academic medicine for sale? (Angell, N Engl J Med , 2000Angell asks a piquant question of academic medical institutions:'Academic medical institutions are themselves growing increasingly beholden to industry. How can they justify rigorous conflict-of-interest policies for individual researchers when their own ties are so extensive?' Answering as to why Academia-industry connect flourishes, she says: 'Some academic institutions have entered into partnerships with drug companies to set up research centers and teaching programs in which students and faculty members essentially carry out industry research. Both sides see great benefit in this arrangement. For financially struggling medical centers, it means cash. For the companies that make the drugs and devices, it means access to research talent, as well as affiliation with a prestigious "brand." Asking herself the question: 'Why shouldn't clinical researchers have close ties to industry?' she answers it decisively tilts academia's inclinations to serve industry interests in various ways, rather than that of biomedical advance:'One obvious concern is that these ties will bias research, both the kind of work that is done and

    2016-01-01

    In order to obtain the biological active compound, α-mangostin, from the traditional native mangosteen (Garcinia mangostana L.), an extraction method for industrial application was explored. A high yield of α-mangostin (5.2%) was obtained by extraction from dried mangosteen pericarps with subsequent purification on macroporous resin HPD-400. The chemical structure of α-mangostin was verified mass spectrometry (MS), nuclear magnetic resonance (1H NMR and 13C NMR), infrared spectroscopy (IR) and UV-Vis spectroscopy. The purity of the obtained α-mangostin was 95.6% as determined by HPLC analysis. The binding of native α-mangostin to human serum albumin (HSA) or transferrin (TRF) was explored by combining spectral experiments with molecular modeling. The results showed that α-mangostin binds to HSA or TRF as static complexes but the binding affinities were different in different systems. The binding constants and thermodynamic parameters were measured by fluorescence spectroscopy and absorbance spectra. The association constant of HSA or TRF binding to α-mangostin is 6.4832×105 L/mol and 1.4652×105 L/mol at 298 K and 7.8619×105 L/mol and 1.1582×105 L/mol at 310 K, respectively. The binding distance, the energy transfer efficiency between α-mangostin and HSA or TRF were also obtained by virtue of the Förster theory of non-radiation energy transfer. The effect of α-mangostin on the HSA or TRF conformation was analyzed by synchronous spectrometry and fluorescence polarization studies. Molecular docking results reveal that the main interaction between α-mangostin and HSA is hydrophobic interactions, while the main interaction between α-mangostin and TRF is hydrogen bonding and Van der Waals forces. These results are consistent with spectral results.

    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.

    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. 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

  20. Food irradiation: benefits and concerns

    International Nuclear Information System (INIS)

    The benefits and concerns about treating foods with ionizing radiation are reviewed. Radioactivity cannot be induced in foods by treatment with gamma rays from 137Cs or 60Co, 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

    In this series, the Bulletin aims to explain the role of the Ombuds at CERN by presenting practical examples of misunderstandings that could have been resolved by the Ombuds if he had been contacted earlier. Please note that, in all the situations we present, the names are fictitious and used only to improve clarity.   Phil* was a candidate for a position in a different group from the one he had been working for. After his board had taken place, Phil asked for an appointment with the Ombuds. In his opinion, the interview went reasonably well. However Phil had some concerns as he had heard that there was no point in him applying as another candidate will get the position. He had decided to apply anyway, encouraged by other people, with the hope that he would get a good rating that could help him get a position in the future, if he didn't get present one. During the interview he was asked some questions that could only have been answered by candidates with  experience related ...

  2. X-ray Structure Analysis of Indazolium trans-[Tetrachlorobis(1H-indazole)ruthenate(III)] (KP1019) Bound to Human Serum Albumin Reveals Two Ruthenium Binding Sites and Provides Insights into the Drug Binding Mechanism

    2016-01-01

    Ruthenium(III) complexes are promising candidates for anticancer drugs, especially the clinically studied indazolium trans-[tetrachlorobis(1H-indazole)ruthenate(III)] (KP1019) and its analogue sodium trans-[tetrachlorobis(1H-indazole)ruthenate(III)] (NKP-1339). Several studies have emphasized the likely role of human serum proteins in the transportation and accumulation of ruthenium(III) complexes in tumors. Therefore, the interaction between KP1019 and human serum albumin was investigated by means of X-ray crystallography and inductively coupled plasma mass spectrometry (ICP-MS). The structural data unambiguously reveal the binding of two ruthenium atoms to histidine residues 146 and 242, which are both located within well-known hydrophobic binding pockets of albumin. The ruthenium centers are octahedrally coordinated by solvent molecules revealing the dissociation of both indazole ligands from the ruthenium-based drug. However, a binding mechanism is proposed indicating the importance of the indazole ligands for binding site recognition and thus their indispensable role for the binding of KP1019. PMID:27196130

  11. Moral considerations concerning income inequality

    Directory of Open Access Journals (Sweden)

    Jurjen P. de Vries

    2015-03-01

    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

  12. Occupational health concerns in the welding industry.

    Science.gov (United States)

    Korczynski, R E

    2000-12-01

    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.

  13. Identity-driven differences in stakeholder concerns about hunting wolves.

    2014-01-01

    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.

  15. Public concerns and alternative nuclear power systems

    International Nuclear Information System (INIS)

    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

    Counselling of patients with chronic hepatitis C infections is often limited to discussions regarding how the virus is transmitted and what can be done to decrease the risk of transmission to others. The purpose of the present study was to document the principal concerns of newly diagnosed and follow-up patients with chronic hepatitis C, and thereby enhance counselling strategies and content. Seventy newly diagnosed and 115 follow-up patients with chronic hepatitis C virus (HCV) infection were initially asked in an open-ended manner (volunteered concerns) and then to prioritize from a prepared list of seven potential concerns (prioritized concerns), to identify those concerns that were of utmost importance to them. The most common volunteered concerns of newly diagnosed patients in decreasing order were: disease progression (27%), premature death (19%), infecting family members (13%), side-effects of treatment (11%) and miscellaneous others. In decreasing order, prioritized concerns included: infecting family members, development of liver cancer, infecting others, development of cirrhosis, social stigma of having liver disease, need for liver transplant and loss of employment. The principal volunteered and prioritized concerns of follow-up patients were similar to those of newly diagnosed patients. Volunteered and prioritized concerns were relatively consistent across the different genders, age groups, ethnic backgrounds, education level, marital status, employment, modes of viral acquisition and in the case of follow-up patients, duration of follow-up. These results indicate that health care providers who focus counselling efforts exclusively on viral transmission are unlikely to address other important concerns of newly diagnosed and follow-up patients with chronic HCV infection.

  1. Fukushima- Ocean Impacts and Public Concerns

    Science.gov (United States)

    Buesseler, K.

    2015-12-01

    The triple disaster of the March 11, 2011 earthquake, tsunami, and subsequent radiation releases at Fukushima Dai-ichi were unprecedented events for the ocean and society. This presentation will provide an overview of studies of Fukushima radionuclides in the ocean. The radioactive releases from Fukushima will be compared to natural and prior human sources. The fate of cesium is largely determined by its soluble nature in seawater, though uptake in sediments does occur via cesium's association with both detrital particles and biological uptake and sedimentation. Cesium's continued supply from the rivers and ongoing leakages at the nuclear power plants suggests that coastal sediments may remain contaminated for decades to come. Although levels of cesium in the ocean and being released from Fukushima more than four years later are orders of magnitude lower than in 2011, other isotopes such as strontium-90 remain of interest as they are elevated relative to cesium in the groundwater and storage tanks at the reactor site. Across the Pacific, Fukushima cesium is starting to be detectable along the west coast of North America. Although models suggest cesium will be at levels well below those considered of human health concern, the public is worried about the lack of ocean monitoring of Fukushima radionuclides. We addressed these public concerns by creating "Our Radioactive Ocean" a citizen-scientist crowd-funded campaign that provides a sampling kit that can use to sample their favorite beach. Once collected, samples are returned to WHOI for analyses of the isotopes of cesium that allow us to distinguish Fukushima cesium from other sources (http://OurRadioactiveOcean.org ). However to measure the low levels of cesium already in the ocean 20 liter samples are needed. To increase public participation, we will also present results from a new wearable sample collector, the "RadBand" which contains a small amount of cesium selective resin that surfers and swimmers can wear on

  4. Recent Advances Concerning Certain Class of Geophysical Flows

    CERN Document Server

    Li, Jinkai

    2016-01-01

    This paper is devoted to reviewing several recent developments concerning certain class of geophysical models, including the primitive equations (PEs) of atmospheric and oceanic dynamics and a tropical atmosphere model. The PEs for large-scale oceanic and atmospheric dynamics are derived from the Navier-Stokes equations coupled to the heat convection by adopting the Boussinesq and hydrostatic approximations, while the tropical atmosphere model considered here is a nonlinear interaction system between the barotropic mode and the first baroclinic mode of the tropical atmosphere with moisture. We are mainly concerned with the global well-posedness of strong solutions to these systems, with full or partial viscosity, as well as certain singular perturbation small parameter limits related to these systems, including the small aspect ratio limit from the Navier-Stokes equations to the PEs, and a small relaxation-parameter in the tropical atmosphere model. These limits provide a rigorous justification to the hydrost...

    2016-01-01

    Objective The goal of this study was to examine links between concerns about community violence and objective and subjective sleep parameters in an adolescent sample. Sex was considered as a moderator of effects. Design The study used a cross-sectional design. Participants The community-based sample included 252 adolescents (53% girls) with an average age of 15.79 years (SD = 0.81) from the Southeastern United States. The sample included 34% African American and 66% European American adolescents from a wide range of socioeconomic backgrounds. Measurements Adolescent-reported community violence concerns were assessed using a composite of 3 separate subscales that measured perceived community safety and threats of community and school violence. Sleep duration and quality were assessed using actigraphy, and subjective sleep problems and daytime sleepiness were measured with subscales of the School Sleep Habits Survey. Results Community violence predicted lower sleep efficiency, more long-wake episodes, and more sleep/wake problems and sleepiness. Sex-related moderation effects revealed that girls in the sample were more vulnerable to the effects of violence concerns on their objective sleep quality. Conclusions Findings highlight the role of community violence concerns on adolescents’ sleep, revealing that greater community violence concerns are linked with lower levels of actigraphy-based and subjective reports of sleep quality, particularly for adolescent girls. Consideration of the mechanisms by which violence concerns may affect sleep is discussed.

There is, however, growing concern in many OECD countries that nuclear education and training is decreasing, perhaps to problematic levels. This booklet, a summary of the full report, conveys the results of a pioneering survey on nuclear education and training in almost 200 organisations in 16 countries. The current situation is presented and causes for concern are examined. Recommendations are made as to the actions governments, academia and industry must take in order to assure that crucial present requirements are met and future options are not precluded. (authors)

  14. Coordination under the Shadow of Career Concerns

    DEFF Research Database (Denmark)

    Koch, Alexander; Morgenstern, Albrecht

    To innovate, firms require their employees to develop novel ideas and to coordinate with each other to turn these ideas into products, services or business strategies. Because the quality of implemented designs that employees are associated with affects their labor market opportunities, career...... concerns arise that can both be ‘good’ (enhancing incentives for effort in developing ideas) and ‘bad’ (preventing voluntary coordination). Depending on the strength of career concerns, either group-based incentives or team production are optimal. This finding provides a possible link between the increased...

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

    International Nuclear Information System (INIS)

    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. What factors mediate the relationship between global self-worth and weight and shape concerns?

    Science.gov (United States)

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

    2016-04-01

    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. PMID:26894257

    2016-03-01

    Predictors and outcomes of weight concerns in pre-adolescent and adolescent girls are well known, but few models have incorporated concerns reported directly by mothers as a predictor, and both eating and exercise outcomes. Using questionnaires, a comprehensive model of 232 pre-adolescent and early adolescent girls' weight concerns, eating restraint, and exercise behavior was tested. Structural equation modeling showed that daughters' weight concerns were predicted primarily by their perceptions of their mothers' concerns about the daughters' weight, as well as by daughters' BMI, appearance conversations with friends, and perceived media pressure. Mothers' concerns with their daughters' weight were indirectly associated with daughters' own concerns, via the daughters' perceptions of their mothers' concerns. Daughters' concerns with their weight were a strong predictor of eating restraint, but not exercise behavior. PMID:26803392

  15. The Concerns of Competent Novices during a Mentoring Year

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available In an innovative group mentoring approach, four experienced midwives mentored four new graduates during their first year of practice. The new graduates were in practice as case-loading registered midwives having completed a three year Bachelor of Midwifery degree. Detailed data about the new graduates’ concerns were collected throughout the year of the mentoring project. A range of practice areas—administrative, working environment, professional culture, clinical issues and the mentor group itself—were prominent issues. New graduates were concerned about their own professional development and about relationships with others particularly relationships within the hospital. Technical questions focussed more on craft knowledge that develops through experience than on clinical skills or knowledge. Identifying these concerns provides a foundation for mentors, preceptors and those designing professional development support programmes for the first year of practice. It may be that new graduate midwives educated in a profession with a narrowly defined scope of practice have a different range of concerns to new graduates who have wider scopes of practice. The use of a group model of mentoring for supporting new graduate midwives proved stimulating for mentors and highly supportive of new graduates.

  18. Relative concerns associated with genetics and surrogacy.

    Science.gov (United States)

    Kirk, M

    Assisted reproductive technologies, incorporating artificial insemination and in-vitro fertilization techniques, are widely practised across Europe. Concern about surrogacy prompted the UK Government to commission a review and consultation on surrogacy arrangements. The ensuing document was concerned primarily with the questions of payment to the surrogate, and the regulation of agencies involved in surrogacy arrangements. This author feels that more fundamental issues should first be debated by both health professionals and society. Genetic aspects of surrogacy merit special attention, particularly regarding the genetic contribution to parenthood and the ownership and use of genetic information. Health professionals need to be fully aware of the ethical implications of advances in genetics and technology when they are applied to assisted reproduction. PMID:9735720

    Most people would like to change something about their bodies and the way that they look, but for some it becomes an obsession. A healthy skin plays an important role in a person's physical and mental wellbeing, whereas a disfiguring appearance is associated with body image concerns. Skin diseases such as acne, psoriasis and vitiligo produce cosmetic disfigurement and patients suffering these and other visible skin conditions have an increased risk of depression, anxiety, feelings of stigmatization and self-harm ideation. Body image affects our emotions, thoughts, and behaviours in everyday life, but, above all, it influences our relationships. Furthermore, it has the potential to influence our quality of life. Promotion of positive body image is highly recommended, as it is important in improving people's quality of life, physical health, and health-related behaviors. Dermatologists have a key role in identifying body image concerns and offering patients possible treatment options. PMID:27283435

  20. 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

We assume a competitive labor market with unobservable effort, where firms condition wages on output as incentive for effort.

    Kaylor, Mary Beth; Wenning, Paul; Eddy, Christopher

    2015-01-01

    Recent research suggests that the resurgence of bed bugs in the U.S. has occurred at an alarming rate. Assumptions have been made that socioeconomic status is not associated with the prevalence of bed bug infestations. Little information is available at the local level, however, about the prevalence of bed bugs in private homes. The authors' pilot study aimed to identify prevalence, knowledge, and concern about bed bugs in one higher income village in Ohio utilizing survey methodology. Responses from 96 individuals who completed the Prevalence, Knowledge, and Concern About Bed Bugs survey were utilized for analysis. The majority of the sample respondents were white and 95% reported that they owned their residence. Only 6% knew someone with bed bugs. Additionally, 52% reported they were somewhat concerned about bed bugs. About 46% reported that they had changed their behavior. For a higher income area, the prevalence was dissimilar to the rate reported in the general public (about 20%). This suggests that bed bugs may be an environmental issue effecting low-income populations disproportionately. Further research is needed in areas of differing socioeconomic levels. PMID:26427264

    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.

  11. Probabilistic Key Management Practical Concerns in Wireless Sensor Networks

    Directory of Open Access Journals (Sweden)

    Rui Miguel Soares Silva

    2008-02-01

    Full Text Available The subject of Key Management in Wireless Sensor Networks has gained increased attention from the security community around the world in the last years. Several proposals were made concerning the peculiarities of resource constrains inherent to sensor devices. One of the most accepted proposals is based on random distribution of keys among the sensor nodes, which was followed by some variants in order to increase its security. In this paper we introduce the mathematical concepts behind this class of proposals through a step-by-step mathematical analysis. This leads to some practical concerns about its applicability to real world applications where the technological constrains strictly compromise the mathematical theoretical models. We demonstrate that the number of communication links needed to assure near 100% network connectivity, is in fact, impractical in nowadays applications.

    Many factors affect how people perceive the world and their environment, and how such perceptions affect lifestyle decisions, yet the relationship between personal perceptions about environmental hazards and diet is rarely examined. In this study, environmental concerns on a local and global scale were examined, along with dietary patterns, to determine if there were associations and age-related differences. The hypothesis that concerns about water pollution might be reflected in choices about seafood consumption was examined. Many aspects of dietary choices varied significantly by age, including (1) younger people ate more "fast food" than others, (2) subjects aged 22-32 yr ate more meals in restaurants than older or younger people, (3) older individuals drank more tea than younger subjects, while younger people drank more soda than older people, and (4) there were few significant differences in total fish and shellfish meals, although young people ate more meals of other types of meat. Individuals who rated their health the best reported significantly fewer seafood meals than others. People who listed pollution as the major environmental problem did not consume seafood less often than others. While pollution was listed as the most important environmental problem globally, people distinguished between air and water pollution only for Singapore. Although Singapore, with its rapidly expanding economy, has reason to be concerned about both water and air pollution, only 14% of those listing pollution as the main Singapore environmental problem mentioned "water pollution." Singapore has been able to take measures to reduce water pollution from internal sources. Respondents considered air pollution a greater problem, perhaps reflecting recent haze disasters from deliberately set forest fires in Indonesia, which are beyond the direct control of Singapore or Singaporeans.

However, the Not-In-My-Back- Yard (NIMBY) opposition and various concerns raised at public hearings may inhibit the expansion of wind energy in Illinois. This study aims to characterize the public beliefs and opinions toward wind energy in central Illinois.

    As a complicated concept with ethical implications, equity or fairness in the field of climate change mitigation concerns the relations not only between individual human beings but also between human beings and the nature. In this paper, after the review of equity between individuals, market and non-market attributes of emissions rights are distinguished and discussed. Based on the argument of equal per capita emissions rights, three types of emissions rights and the concept of minimum emissions rights as social security are proposed.

    An alarming rise in rates of paediatric population committing self-immolation acts is a growing social and medical problem. In recent times there seems to be a rising concern in paediatric population. A study was conducted at a government tertiary care burn centre over 5 years in paediatric age group of peer pressure leaving them vulnerable. A multidisciplinary care involving medical, psychological and social support is required. Identifying children at risk and proper counselling and support can form an important strategy at prevention rather than cure. PMID:26803366

    The safety of the food supply is a subject of intense interest to consumers, particularly as a result of large scale outbreaks that involve hundreds and sometimes thousands of consumers. During the last decade this concern about food safety has expanded to include the diets of companion animals as a result of several incidences of chemical toxicities and infectious disease transmission. This has led to increased research into the causes and controls for these hazards for both companion animals and their owners. The following summary provides an introduction to the issues, challenges, and new tools being developed to ensure that commercial pet foods are both nutritious and safe.

  4. Parental concerns in children requiring palliative care

    2008-01-01

    Full Text Available Children with advanced, life-limiting illness have unique needs which are different from those of adults. Pediatric palliative care is an under developed specialty. Aims : To identify concerns of parents of children with advanced, incurable cancers, and to elicit their attitudes toward revealing the diagnosis and prognosis to the sick child. Method : This study was carried out in a large tertiary cancer center in India. Parents of 20 pediatric palliative care patients attending the outpatient department were interviewed and emerging themes identified. Results : Parents showed varying degrees of anticipatory grief. Most families were financially strained. Most parents were reluctant to discuss disease and dying with the child. Siblings were rarely told or directly involved in care. There was resistance to allowing the palliative care team to communicate with the patient. Patients did not receive any formal support. Parents identified family and neighbors as the main sources of support. Conclusions : Parental attitudes hinder open communication with dying children in India. There is a need for research to explore the concerns of families of children with fatal illness. Specialist training is required for professionals working in pediatric palliative care to address this issue.

  6. Global Governance: Some concerns about authentic democracy addressed

    Directory of Open Access Journals (Sweden)

    Gillian Brock

    2011-05-01

    Full Text Available In this paper I take up a commonly voiced concern about the viability of global governance in general, and cosmopolitan democracy in particular, namely, whether genuine democracy can be achieved at the international level. Some (such as, Will Kymlicka argue that genuine democracy is only possible within nation-states, because authentic deliberation requires common nationality or identity, which generates the trust and solidarity necessary to sustain deliberation and democracy. Through analysis of the argument and consideration of the requirements of genuine democracy, we can see that these concerns can be addressed. I go on to suggest that the major challenge facing models of global governance is not one concerning lack of common identity, solidarity, or opportunities for authentic deliberation, rather, it lies elsewhere. We can assess global governance arrangements in terms of two main variables, which are sometimes in tension: effectiveness and accountability. We want systems of global governance to incorporate both considerations. Accountability can take the form of democratic procedures but alternative forms of accountability are also possible. Furthermore, a system of governance that both effectively attends to people’s interests and is suitably accountable can certainly claim to have adequate democratic credentials on the “Responsive Democracy” view I discuss.

    Attwood, Angela S

    2012-01-01

    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. PMID:22645036

  10. Some Findings Concerning Requirements in Agile Methodologies

    Science.gov (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.

  11. Operational concerns in addressing insider protection

    International Nuclear Information System (INIS)

    One of the greater challenges facing today's nuclear industry is developing and implementing an insider protection system. Thorough employee background investigations alone do not suffice as the system to assure that the authorized employee does not sabotage the facility. The real difficulties arise when physical or administrative barriers are placed in the operational environment of the plant. People have to be used to control the plant, and usually production is a key priority of management responsibilities. Implementing an insider protection system that provides the least operational impacts and meets the intended safeguards objectives has to be approached with a team attitude by all of management. Operational concerns are some of the most important considerations that must be factored into the insider protection system

    Full Text Available Oral cancer is the largest group of cancer that categorizes into the head and neck region and worldwide health problem. Exact cause of oral cancer is unknown. Risk factors for cancer could be varied including Iron deficiency anemi a, are alcohol, tobacco, immunologic susceptibility, gene mutations, epithelial cell growth, suppressor proteins and disease of chemotherapy, such as in cases of lymphoma and leukemia. Role of viruses have also been reported in the etiology. Dietary factor s such as high fat and low fiber may play a role in carcinogenesis in some sites. High incidence of alcoholism is relevant because alcohol intake has been related to an increase risk of developing oral cancer. Other signaling factors have also been propose d to have a role. The paper presents a review on oral cancer, its causes & concern.

  13. Visually depicting cancer fears: Beyond biomedical concerns

    Directory of Open Access Journals (Sweden)

    Carolyn Brooks

    2014-07-01

    Full Text Available This manuscript is a reaction to the high prevalence of breast cancer amongst Aboriginal women. Our work calls for more attention to the effects of race, gender, and class on cancer fears and related experiences. The shock of a cancer diagnosis and fears of recurrence can leave patients feeling that their lives are out of control. Combining the visual method of photovoice with focus groups and in-depth interviews, we develop an understanding of cancer experiences that includes fears related to: socio-economic realities; supporting families both emotionally and financially; environmental concerns, especially those that arise from living on reserve; race and racism; and cultural beliefs. Breast cancer experiences are shown to be significantly linked to history and the impact of colonization, neo-colonialism and point to the importance of a postcolonial feminist framework and cancer support policies informed by a lens of cultural safety.

  14. Three dialogues concerning robots in elder care.

    Metzler, Theodore A; Barnes, Susan J

    2014-01-01

    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. PMID:24320977

    2002-01-01

    Aiming at addressing the ethical aspects concerning nurses' managerial activities, the authors of this work referred to Etzioni and adopted a hospital classification as a reference of organization in which consent is based on the internalization of rules accepted as legitimate. Regarding patients, their need to adapt to medical behavior and hospital rules through internalization is considered to be a result of physicians', nurses' and the hospital's power. However, the authors view that such internalization is naive, without consent, especially by taking into account that most Brazilian patients do not know that they should or should not consent and are used to obeying. Thus, the work focused on nurses' managerial actions, indicating that they must be based on professional values, the Nursing ethical code as well as on the rights of hospitalized patients, thus integrating qualified care guided by respect, free consent and promotion of patients as the protagonists and subjects of care.

  16. Antifungal Drug Resistance - Concerns for Veterinarians

    2009-10-01

    Full Text Available In the 1990s, there were increased incidences of fungal infectious diseases in human population which might be due to increase in immunosuppressive diseases. But the major concern was increase in prevalence of resistance to antifungal drugs which were reported both in the fungal isolates of human beings and that of animal origin. In both animals and human beings, resistance to antimicrobial agents has important implications for morbidity, mortality and health care costs, because resistant strains are responsible for bulk of infection in animals and human beings, and large number of antimicrobial classes offers more diverse range of resistance mechanisms to study and resistance determinants move into standard well-characterized strains that facilitates the detailed study of molecular mechanisms of resistance in microorganisms. Studies on resistance to antifungal agents has been lagging behind that of antibacterial resistance for several reasons, the foremost reason might be fungal agents were not recognized as important animal and human pathogens, until relatively in recent past. But the initial studies of antifungal drug resistance in the early 1980s, have accumulated a wealth of knowledge concerning the clinical, biochemical, and genetic aspects of this phenomenon. Presently, exploration of the molecular aspects for antifungal drug resistance has been undertaken. Recently, the focus was on several points like developing a more detailed understanding of the mechanisms of antimicrobial resistance, improved methods to detect resistance when it occurs, methods to prevent the emergence and spread of resistance and new antimicrobial options for the treatment of infections caused by resistant organisms.

  17. The Death of the Concerned Intellectual?

    Directory of Open Access Journals (Sweden)

    Chongyi Feng

    2005-08-01

    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. HANFORD CHEMICAL VAPORS WORKER CONCERNS & EXPOSURE EVALUATION

    Energy Technology Data Exchange (ETDEWEB)

    ANDERSON, T.J.

    2006-12-20

    Chemical vapor emissions from underground hazardous waste storage tanks on the Hanford site in eastern Washington State are a potential concern because workers enter the tank farms on a regular basis for waste retrievals, equipment maintenance, and surveillance. Tank farm contractors are in the process of retrieving all remaining waste from aging single-shell tanks, some of which date to World War II, and transferring it to newer double-shell tanks. During the waste retrieval process, tank farm workers are potentially exposed to fugitive chemical vapors that can escape from tank headspaces and other emission points. The tanks are known to hold more than 1,500 different species of chemicals, in addition to radionuclides. Exposure assessments have fully characterized the hazards from chemical vapors in half of the tank farms. Extensive sampling and analysis has been done to characterize the chemical properties of hazardous waste and to evaluate potential health hazards of vapors at the ground surface, where workers perform maintenance and waste transfer activities. Worker concerns. risk communication, and exposure assessment are discussed, including evaluation of the potential hazards of complex mixtures of chemical vapors. Concentrations of vapors above occupational exposure limits-(OEL) were detected only at exhaust stacks and passive breather filter outlets. Beyond five feet from the sources, vapors disperse rapidly. No vapors have been measured above 50% of their OELs more than five feet from the source. Vapor controls are focused on limited hazard zones around sources. Further evaluations of vapors include analysis of routes of exposure and thorough analysis of nuisance odors.

  20. Concerns in Marine Renewable Energy Projects

    Energy Technology Data Exchange (ETDEWEB)

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

    2010-06-17

    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.

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

    International Nuclear Information System (INIS)

    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)

    Landeweer, Elleke G M; Abma, Tineke A; Widdershoven, Guy A M

    2011-05-01

    In the closed wards of mental health institutions, moral decisions are made concerning the use of forced seclusion. In this article we focus on how these moral decisions are made and can be improved. We present a case study concerning moral deliberations on the use of seclusion and its prevention among nurses of a closed mental health ward. Moral psychology provides an explanation of how moral judgments are developed through processes of interaction. We will make use of the Social Intuitionist Model of Jonathan Haidt that emphasizes the role of emotions, intuitions and the social context in moral judgments and reasoning. We argue that this model can help to explain social dynamics in the context of enforced seclusion. In the discussion we explore how moral psychology can be complemented with the normative perspective of dialogical ethics to develop strategies for improving psychiatric practices. We conclude that social processes play an important role in moral deliberations and that moral development can be fostered by bringing in new perspectives in the dialogue. Moral case deliberation provides a practical tool to systematically organize moral reflections among nurses on the work floor.

  6. Concerning the justiciability of demand forecasts

    International Nuclear Information System (INIS)

    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)

    R. N. Singh

    2012-12-01

    Full Text Available The paper is concerned with the hydrogeological appraisal of the proposed mining operations in theThar lignite field in Sindh, Pakistan. The Thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. In the Thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and makes highwall slopes potentially unsafe. It is, therefore, necessary to dewater the rock mass before commencingmining excavations. The paper describes the proposed mine dewatering scheme to facilitatedepressurising of the rock mass surrounding the mining excavations. Inflow prediction of groundwater tothe surface mining excavation was carried out using a SEEP/W finite element software package.

    2003-11-01

    Biotechnology was used in the first generation of so-called 'GM' crops to provide growers with complimentary and sometimes alternative crop management solutions to pesticides. Selected host genes or genes identified from other plants or non-plant sources are modified or transferred to a crop plant. The new or altered protein expression resulting from these modifications confer on the plant a desired physiological trait, such as resistance to particular herbicides or insect pests. Second generation modifications provide traits such as enhanced nutritional or health-promoting characteristics that are of benefit to consumers. The commonly raised concerns about possible implications for human health are: inherent toxicity of the novel gene and their products, the potential to express novel antigenic proteins or alter levels of existing protein allergens, the potential for unintended effects resulting from alterations of host metabolic pathways or over expression of inherently toxic or pharmacologically active substances and the potential for nutrient composition in the new food occur differing significantly from a conventional counterpart. Foods produced using biotechnology are subjected to far greater levels of scrutiny than foods produced by traditional plant breeding techniques. The accepted analytical, nutritional and toxicological methods employed to support this scrutiny and to assess and assure that a 'GM' food is a safe and nutritious as its 'non-GM' counterpart are discussed. The challenges associated with identifying unintended effects in whole GM foods and the promise new (proteomics/genomic) technologies offer opposite traditional toxicity testing paradigms are appraised.

    Full Text Available The purpose of this article is to analyse the International Civic and Citizenship Education Study (ICCS use of discussions on social and political issues and then problematize the meaning of “discussions” – in particular, the topic of discussion – through a qualitative analysis of actual discussions in the classroom. A qualitative study of classroom discussions is used to shed light on everyday preconditions between teacher and students. The topic of discussion,is analysed as a social and discursive construction. Political matters such as institutional issues and (international affairs in the ICCS-study are also mostly the focus for the teachers in the classroom study. However, the interaction between teachers and students would seem to indicate that choice of issues for discussion always is a political choice. If students are imagined througha lens of being citizens, already in school, then choice of issues for discussion could be understood as a process of negotiation between the teacher and the students. The issues for discussion can therefore be connected to a notion of legitimate democratic participation concerning mutually recognized issues.

  11. Wireless Network Security Vulnerabilities and Concerns

    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.

  12. Ubiquitous Health Monitoring Systems: Addressing Security Concerns

    Full Text Available Problem statement: It is important to secure the transmission of patient’s EHR in remote health monitoring systems. Security is among the main issues that need to be realized for the adaption of this monitoring technology. The face of healthcare is changing as ubiquitous computing technologies are being incorporated into the existing infrastructure. We specify the requirements, needed security mechanism, outstanding issues and the future challenges as well as the open problems that need to be achieved. Approach: Although there were benefits to technology, approaches that offer reliable privacy and security features must be presented to users in order to make these systems socially accepted. Results: We investigated the privacy and security implications generated from the deployment of remote health monitoring technology. To achieve these security requirements, building on the strengths of Transport Layer Security (TLS protocol, a trust negotiation approach was proposed. The application of this approach results in significant improvements in overcoming security related concerns compared to the traditional identity-based only access control techniques. Conclusion: We believe these considerations will eventually contribute toward an efficient and practical deployment of remote monitoring systems.

    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.

  14. [Tissue grafts: an activity concerning many patients].

    Tissue allografts mainly include corneas, bone (and cartilage, tendon, ligament, aponevrosis), skin, vessels and cardiac valves. All these grafts have been widely used for many years and were the subject of a large number of experimental and clinical studies. The different steps allowing the obtention of different tissue allografts have in fact a common organization through tissue procurement and banking activities. Tissue banks have a central situation ensuring security, safety, traceability and distribution of tissues. Appropriate organization of the banks, and respect of high level standards are thus mandatory. Tissue transplantation activity in France has been studied through national surveys: they concern more than 600 hospitals and clinics, and grafts procured in France (excluding imported allografts) are around 15,000 a year. Precise regulation implied by the bioethical law published in 1994 and homogeneous organization of the activity allow the use of stringent and regularly updated standards, allowing the distribution to the patients of safe grafts procured in ethical conditions. The actual shortage of tissue allografts in France implies increasing procurement through a better organization of retrieval in hospitals and clinics and donation promotion. PMID:9501596

  15. Resolving issues concerning Eskdalemuir geomagnetic hourly values

    2011-02-01

    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 http://www.wdc.bgs.ac.uk/, 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.

    2016-06-01

    The history of medicine is replete with examples of debunked myths, and in daily clinical dermatological practice, we must still counter many misconceptions regarding pigmented lesions, both with patients and other medical practitioners. Debunking myths and attempting to explain the reasons for these erroneous beliefs are the purposes of this review. The literature review has been partially guided by the results obtained from an online questionnaire conducted on an Italian website (www.vediamocichiara.it) from February 15, 2015 to March 15, 2015. The remaining discussed were selected on the basis of the existing literature and our personal experience. In order to explore these misconceptions, the following are the seven most salient questions that require investigation: (i) Is it dangerous to excise moles?; (ii) Is it dangerous to traumatize moles?; (iii) Are plantar moles worrisome?; (iv) Is it necessary to selectively apply sunscreen to moles?; (v) Is it inadvisable to partially biopsy a melanoma?; (vi) Do moles turn into melanoma?; and (vii) Is it necessary to perform sentinel lymph node biopsy for thin melanomas and for atypical Spitz naevi? Myths are ubiquitous, being prevalent in dermatological practice, with many of them concerning pigmented skin lesions. By encouraging critical analysis by patients and medical practitioners, the birth and perpetuation of myths can potentially be minimized, for the ultimate benefit of patients. This requires a scientific approach to be rigorously applied to dermatology, with critical questioning of unsubstantiated hypotheses including those emanating from the mass media as well as from respected sources.

  17. Recent concerns about stunning and slaughter.

    Gregory, N G

    2005-07-01

    This review summarises information that is relevant to concerns that have recently been expressed about stunning and slaughter. It is known that captive bolt stunning can result in brain material passing to the lungs via the jugular veins. If future studies show that BSE prions pass beyond the lungs to the edible carcass, there will be a move away from captive bolt stunning in large cattle towards electrical stunning. Greater use of electrical stunning in large cattle will increase the importance of blood splash in the beef industry. The theoretical causes of blood splash are reviewed to improve our understanding of this problem. In some situations it can be due to excessive venous pressure causing rupture of a capillary bed some distance from the source of the pressure rise, but it is not known whether this applies to electrical stunning. Gas stunning is replacing electrical stunning for poultry because it can reduce blood spots, which is a similar condition to blood splash. Several gas stunning methods are now being used, but it is not clear which of these is the most humane. Anoxic stunning leads to carcass convulsions and this causes more carcass damage. In fish, recent developments in electrical stunning are showing promise in overcoming problems with carcass damage. It is recommended that rock lobsters should be chilled or frozen before butchery, to ensure a humane death. PMID:22063747

  20. Polymyxins: Antimicrobial susceptibility concerns and therapeutic options

    2011-01-01

    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.

  1. Cholera:a great global concern

    Cholera, caused by the infection of toxigenicVibrio cholerae (V. cholerae)to humans, is a life threatening diarrheal disease with epidemic and pandemic potential. TheV. cholerae, both O1 and O139 serogroups, produce a potent enterotoxin (cholera toxin) responsible for the lethal symptoms of the disease. TheO1 serogroup has two biotypes (phenotypes), classical and El Tor; each of which has two major serotypes (based on antigenic responses), Ogawa and Inaba and the extremely rare Hikojima.V. choleraeO1 strains interconvert and switch between the Ogawa and Inaba serotypes. Fluid and electrolyte replacement is the mainstay of treatment of cholera patients; the severe cases require antibiotic treatment to reduce the duration of illness and replacement of fluid intake. The antibiotic therapy currently has faced difficulties due to the rapid emergence and spread of multidrug resistantV. cholerae causing several outbreaks in the globe. Currently, cholera has been becoming endemic in an increasing number of geographical areas, reflecting a failure in implementation of control measures. However, the current safe oral vaccines lower the number of resistant infections and could thus represent an effective intervention measure to control antibiotic resistance in cholera. Overall, the priorities for cholera control remain public health interventions through improved drinking water, sanitation, surveillance and access to health care facilities, and further development of safe, effective and appropriate vaccines. Thus, this review describes the facts and phenomena related to the disease cholera, which is still a great threat mainly to the developing countries, and hence a grave global concern too.

  2. Research and Development Concerning Coalbed Natural Gas

    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 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.

  8. Malaysia's contributions towards global climate change concerns

    International Nuclear Information System (INIS)

    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.

  11. Nuisance Odors: Is there a Concern - 12340

    International Nuclear Information System (INIS)

    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

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

  14. A few problems concerning population science.

    Science.gov (United States)

    Xu, D

    1981-05-27

    This paper discusses problems concerning population science in China within a Marxist perspective. In contrast to capitalism, the socialist society is built on the foundation of the socialist public ownership of the means of production. The socialist law of population, as distinct from the capitalist, means the inevitability of population planning under the socialist mode of production. If rapid population growth is allowed to continue, the yearly increment of material wealth will be conserved by the additional population which will thereby nullify the cultural and material needs of the people. Therefore, population growth planning is necessary to control reproduction and material production as well as the development of the national economy. 3 differences between Chinese population theory and that of the neoMalthusians are discussed: 1) whereas the neoMalthusians propose to safeguard the capitalist system, the Chinese theory is to consolidate the socialist system, 2) Malthusianism emphasizes population growth and ignores, unlike the Chinese system, the possibility of increasing production while achieving population control by degrees, and 3) responsibility for controlling "surplus population" is placed on the working people by neoMalthusians but on the elites in the Chinese system. Recent efforts in China are to control the population by reducing families to one child. In the past 30 years, a series of contradictions have developed in the development of the economy in relation to population growth: 1) distinct disproportion arises between the growth of the total population (66.7% between 1952-78) and that of the means of subsistence (5.4%/year between 1952-78); 2) if population growth is not controlled, a contradiction will occur between those of working ages and the growth of the means of production; and 3) the disproportion between the quality of population and the needs of the modern socialist system. Under the socialist system, population control is

    2013-01-01

    In recent years cloud computing is the subject of extensive research in the emerging field of information technology and has become a promising business.The reason behind this widespread interest is its abilityto increase the capacity and capability of enterprises,having no investment for new infrastructure,no software license requirement and no need of any training. Security concern is the main limitation factor in the growth of this new born technology.The secur-ity responsibilities of both,the provider and the consumer greatly differ between cloud service models.In this paper we discuss a variety of security risks,authentication issues,trust,and legal regularity in cloud environment with consumer perspective.Early research focused only on techni-cal and business consequences of cloud computing and ignored consumer perspective.There-fore,this paper discusses the consumer security and privacy preferences.

  16. Behavioural controversy concerning homo economicus: a Humean perspective

    2014-05-01

    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.

  17. Essays concerning the cellulosic biofuel industry

    Science.gov (United States)

    Rosburg, Alicia Sue

    Despite market-based incentives and mandated production, the U.S. cellulosic biofuel industry has been slow to develop. This dissertation explores the economic factors that have limited industry development along with important economic tradeoffs that will be encountered with commercial-scale production. The first essay provides an overview of the policies, potential, and challenges of the biofuel industry, with a focus on cellulosic biofuel. The second essay considers the economics of cellulosic biofuel production. Breakeven models of the local feedstock supply system and biofuel refining process are constructed to develop the Biofuel Breakeven (BioBreak) program, a stochastic, Excel-based program that evaluates the feasibility of local biofuel and biomass markets under various policy and market scenarios. An application of the BioBreak program is presented using expected market conditions for 14 local cellulosic biofuel markets that vary by feedstock and location. The economic costs of biofuel production identified from the BioBreak application are higher than frequently anticipated and raise questions about the potential of cellulosic ethanol as a sustainable and economical substitute for conventional fuels. Program results also are extended using life-cycle analysis to evaluate the cost of reducing GHG emissions by substituting cellulosic ethanol for conventional fuel. The third essay takes a closer look at the economic trade-offs within the biorefinery industry and feedstock production processes. A long-run biomass production through bioenergy conversion cost model is developed that incorporates heterogeneity of biomass suppliers within and between local markets. The model builds on previous literature by treating biomass as a non-commoditized feedstock and relaxes the common assumption of fixed biomass density and price within local markets. An empirical application is provided for switchgrass-based ethanol production within U.S. crop reporting districts

    Full Text Available The article revealed the opinions of the pupils’ parents about where should their children’s peers with minor mental disorders and/or physical disabilities learn and develop. Based uponthe results of studies conducted in 2002 and 2012 it becomes clear that the changes of education reality had impact also to the parents’ of pupils approach to integrated education: former vision of inclusive education became a reality. Respondents agree that their children may attend general education school together with their disabled peers. At the beginning of the year 2002 half of the respondents said that children with disabilities may learn in common classes. This is the model of natural integration. The study repeated after ten years revealed that the opinionsof the parents apparently had changed: 52 percent of respondents indicated that children with disabilities should learn in separate classes.

    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.

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.

  6. Current understanding concerning intestinal stem cells

    Science.gov (United States)

    Cui, Shuang; Chang, Peng-Yu

    2016-01-01

    In mammals, the intestinal epithelium is a tissue that contains two distinct pools of stem cells: active intestinal stem cells and reserve intestinal stem cells. The former are located in the crypt basement membrane and are responsible for maintaining epithelial homeostasis under intact conditions, whereas the latter exhibit the capacity to facilitate epithelial regeneration after injury. These two pools of cells can convert into each other, maintaining their quantitative balance. In terms of the active intestinal stem cells, their development into functional epithelium is precisely controlled by the following signaling pathways: Wnt/β-catenin, Ras/Raf/Mek/Erk/MAPK, Notch and BMP/Smad. However, mutations in some of the key regulator genes associated with these signaling pathways, such as APC, Kras and Smad4, are also highly associated with gut malformations. At this point, clarifying the biological characteristics of intestinal stem cells will increase the feasibility of preventing or treating some intestinal diseases, such as colorectal cancer. Moreover, as preclinical data demonstrate the therapeutic effects of colon stem cells on murine models of experimental colitis, the prospects of stem cell-based regenerative treatments for ulcerous lesions in the gastrointestinal tract will be improved all the same.

  8. PBT assessment and prioritization of contaminants of emerging concern: Pharmaceuticals.

    Science.gov (United States)

    Sangion, Alessandro; Gramatica, Paola

    2016-05-01

    The strong and widespread use of pharmaceuticals, together with incorrect disposal procedures, has recently made these products contaminants of emerging concern (CEC). Unfortunately, little is known about pharmaceuticals' environmental behaviour and ecotoxicity, so that EMEA (European Medicines Agency) released guidelines for the pharmaceuticals' environmental risk assessment. In particular, there is a severe lack of information about persistence, bioaccumulation and toxicity (PBT) of the majority of the thousands of substances on the market. Computational tools, like QSAR (Quantitative Structure Activity Relationship) models, are the only way to screen large sets of chemicals in short time, with the aim of ranking, highlighting and prioritizing the most environmentally hazardous for focusing further experimental studies. In this work we propose a screening method to assess the potential persistence, bioaccumulation and toxicity of more than 1200 pharmaceutical ingredients, based on the application of two different QSAR models. We applied the Insubria-PBT Index, a MLR (Multiple Linear Regression) QSAR model based on four simple molecular descriptors, implemented in QSARINS software, and able to synthesize the PBT potential in a unique cumulative value and the US-EPA PBT Profiler that assesses the PBT behaviour evaluating separately P, B and T. Particular attention was given to the study of Applicability Domain in order to provide reliable predictions. An agreement of 86% was found between the two models and a priority list of 35 pharmaceuticals, highlighted as potential PBTs by consensus, was proposed for further experimental validation. Moreover, the results of this computational screening are in agreement with preliminary experimental data in the literature. This study shows how in silico models can be applied in the hazard assessment to perform preliminary screening and prioritization of chemicals, and how the identification of the structural features, mainly

    2016-01-01

    The agricultural sector in Norway has undergone structural changes over the past 50 years. The objective of this study was to analyze the distribution of concerns about farm economy, work time, and mental complaints among Norwegian farmers. In a sample of single principal owner-operators (n = 2,676), we calculated the unadjusted and adjusted odd ratios (ORs) for concerns about the farm economy, concerns for insufficient time to complete work, and high symptom load of mental complaints. Structural equation modeling (SEM) was used to explore the associations between farm characteristics, concerns, and mental health. Farmers had a high probability for an increased symptom load of mental complaints. The level of farm income was more strongly associated with economic concerns and mental health concerns when a major part of total household income resulted from farming. The high workload required in farming combined with off-farm supplemental employment was additionally associated with higher levels of time concerns and mental complaints. Norwegian farmers have a relatively high workload both in farming and in off-farm work but are able to make sustainable plans for their individual workload needs. The high individual workload in both these arenas poses a challenge, but was not associated with a greater probability for a high symptom load of mental complaints.

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

    International Nuclear Information System (INIS)

    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

    2015-02-01

    Full Text Available To address public concerns that threat the sustain-ability of local societies, supporting public participation by shar-ing the background context behind these concerns is essentially important. We designed a SOCIA ontology, which was a linked data model, for sharing context behind local concerns with two approaches: (1 structuring Web news articles and microblogs about local concerns on the basis of geographical regions and events that were referred to by content, and (2 structuring public issues and their solutions as public goals. We moreover built a SOCIA dataset, which was a linked open dataset, on the basis of the SOCIA ontology. Web news articles and microblogs related to local concerns were semi-automatically gathered and structured. Public issues and goals were manually extracted from Web content related to revitalization from the Great East Japan Earthquake. Towards more accurate extraction of public concerns, we investigated feature expressions for extracting public concerns from microblogs written in Japanese. To address a technical issue about sample selection bias in our microblog corpus, we formulated a metric in mining feature expressions, i.e., bias-penalized information gain (BPIG. Furthermore, we developed a prototype of a public debate support system that utilized the SOCIA dataset and formulated the similarity between public goals for a goal matching service to facilitate collaboration.

    Involuntary autobiographical memories are conscious memories of personal events that come to mind with no preceding attempts at retrieval. It is often assumed that such memories are closely related to current concerns - i.e., uncompleted personal goals. Here we examined involuntary versus voluntary...... (deliberately retrieved) autobiographical memories in relation to earlier registered current concerns measured by the Personal Concern Inventory (PCI; Cox & Klinger, 2000). We found no differences between involuntary and voluntary memories with regard to frequency or characteristics of current concern related...... contents. However, memories related to current concerns were rated as more central to the person's identity, life story and expectations for the future than non-concern related memories, irrespective of mode of recall. Depression and PTSD symptoms correlated positively with the proportion of current...

  17. Targeting clinician concerns about exposure therapy: A pilot study comparing standard vs. enhanced training.

    Farrell, Nicholas R; Kemp, Joshua J; Blakey, Shannon M; Meyer, Johanna M; Deacon, Brett J

    2016-10-01

    Owing to concerns about the safety and tolerability of exposure therapy, many clinicians deliver the treatment in an overly cautious manner, which may limit its effectiveness. Although didactic training in exposure reduces clinician concerns about the treatment to a moderate extent, improved training strategies are needed to minimize these concerns and improve exposure delivery. The present study compared the effectiveness of a standard (i.e., didactic) exposure therapy training model to an "enhanced" training paradigm encompassing strategies derived from social-cognitive theory on attitude change. Clinicians (N = 49) were assigned to one of the two training approaches. Relative to standard training, clinicians who received enhanced training showed: (a) significantly greater reductions in concerns about exposure from pre- to post-training, and (b) superior self-reported delivery of the treatment. Reduction in concerns during training mediated the effects of training condition on clinicians' self-reported exposure delivery. These findings underscore the importance of addressing clinician concerns about exposure therapy in training contexts. PMID:27567972

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

    Directory of Open Access Journals (Sweden)

    Elias Frederico

    2013-12-01

    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.

    2016-01-01

    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.

  2. Animal welfare and society concerns finding the missing link.

    2014-11-01

    Young adults in developed countries are distanced from agriculture and the meat industry needs to do a better job of communicating with them. A major welfare concern is slaughter without stunning. Other concerns, such as poor stunning or high levels of bruising, can be easily corrected by management who is committed to maintaining high standards. Another concern is biological system overload, occurring when animals are bred for more productivity. Researchers and industry need to determine optimum production levels instead of maximums. Retailers are major drivers of animal welfare standards enforcement and they respond to pressure from both activists and consumers. PMID:24928166

    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.

    2016-07-01

    This study explored the fears and concerns of 19 Iranian diabetic women using a phenomenological approach. Semistructured individual interviews were conducted; each interview was transcribed verbatim and analyzed simultaneously using Van Manen's method. Data analysis resulted in the emergence of two main themes: (1) "a vague and uncertain future" with sub-themes of "fears of dependency," "loneliness," "disease complications," and "children's future"; and (2) "changing lifestyles" with sub-themes of "dietary restrictions" and "insulin injection." Psychological concerns are common in Iranian diabetic women. These concerns can contribute to poor disease self-management. Thus, it is hoped that identifying these concerns can lead to better management of these issues and a better outcome in diabetic patients. PMID:25305192

    2015-11-01

    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.

    We introduce a molecular dynamics/quantum mechanics/continuum solvent model (MD/QM/CSM) approach to investigate binding mechanisms of host-guest systems. The representative conformations of host, guest, and their complex generated from MD simulations at the molecular-mechanics level are used for binding free energy calculations based on a QM/CSM model. We use this approach to explore the binding mechanisms of β-cyclodextrin (β-CD) and 2, 6-di-methyl-β-CD (DM-β-CD) with various guest molecules. Our results suggest that solvent effects play a more important role in determining the relative binding affinities of DM-β-CD than those of β-CD mainly because the former is more flexible than the latter.

  7. When environmental action does not activate concern: the case of impaired water quality in two rural watersheds.

    2014-12-01

    Little research has considered how residents' perceptions of their local environment may interact with efforts to increase environmental concern, particularly in areas in need of remediation. This study examined the process by which local environmental action may affect environmental concern. A model was presented for exploring the effects of community-based watershed organizations (CWOs) on environmental concern that also incorporates existing perceptions of the local environment. Survey data were collected from area residents in two watersheds in southwestern Pennsylvania, USA, an area affected by abandoned mine drainage. The findings suggest that residents' perceptions of local water quality and importance of improving water quality are important predictors of level of environmental concern and desire for action; however, in this case, having an active or inactive CWO did not influence these perceptions. The implications of these findings raise important questions concerning strategies and policy making around environmental remediation at the local level.

  8. National income and environmental concern: Observations from 35 countries.

    Science.gov (United States)

    Lo, Alex Y

    2016-10-01

    National income produces mixed impacts on public environmental concern. In a cross-national survey, environmental concern was measured in terms of propensity to act and environmental risk perception. Results of a multilevel regression analysis show that these two measures respond to gross domestic product per capita in opposite ways. Citizens of advanced industrial countries are more likely than those of lower-income countries to contribute to environmental protection. However, they are less likely to see the harmful impacts on the environment as very dangerous. Using an indicator of national adaptive capacity, this article demonstrates that environmental risk perception is a function of a country's estimated capacity for coping with condition changes. The stronger sense of collective security among citizens of wealthier nations offers a possible explanation for the negative effects of national income. These results indicate the complex relationship between development and public environmental concern across countries.

    Zika virus, as highlighted by the World Health Organization in February 2016, has emerged as a public health emergency of international concern. Zika virus is enveloped and icosahedral, and has a nonsegmented, single-stranded, positive-sense RNA genome. It belongs to Flaviviridae family. Aedes aegypticus mosquito is the known vector. Transmission is anthroponotic (human to vector to human) during outbreaks, or occurs perinatally in utero, sexually, and via transfusion of infected blood. Zika virus is turning out to be a major public health concern. Not only has it shown dramatic teratogenic association and caused serious neurological concerns but it has also spread around the globe. Countries that have not yet been affected by Zika virus should adopt proper preventive methods to limit its spread in the population. PMID:27418843

However research into information system literature indicates that CEOs are valued as key players in the management of IT to secure that the IT strategy is aligned with the business strategy. Based on the fact that very little prior research exists on the CEOs' interests and concerns...... in relation to the ERP system in the second wave, we employed an interpretive explorative case study with a grounded approach carried out through open interviews with CEOs. The research was conducted in three mid-size Danish production companies all of which have an ERP system. The contribution of this paper...

  13. A Review of Universal Grammar Concerning Second Language Acquisition Research

    Institute of Scientific and Technical Information of China (English)

    李倩

    2014-01-01

    Chomsky’s Universal Grammar (UG) theory not only answers“the logical problem of language acquisition”, but also provides insights and thoughts for second language acquisition (SLA) research on both theoretical and empirical level. However, there are many problems of UG-based research. On the theoretical aspect, UG-based approach left untouched many areas apart from“core grammar”and the continual development of the theory is problematic to second language researchers. On the empiri-cal aspects, most experiments reveal problems with the design and data collection process. In short, the evaluation of UG concern-ing SLA should be developmental and comprehensive.

    There is a burgeoning body of academic literature (e.g. Becken, 2007; Gössling et al, 2006; Hares et al, 2010) that examines if and how consumer concern about climate change manifests itself in tourist behavioural practices. These works build on a wealth of previous studies that consider how consumer concern over issues of sustainable development may also affect tourist behaviour. Indeed, whilst tourism’s climate impacts have lately been a hot topic, there is no doubt that issues of climate c...

    Deploying cloud computing in an enterprise infrastructure bring significant security concerns. Successful implementation of cloud computing in an enterprise requires proper planning and understanding of emerging risks, threats, vulnerabilities, and possible countermeasures. We believe enterprise should analyze the company/organization security risks, threats, and available countermeasures before adopting this technology. In this paper, we have discussed security risks and concerns in cloud computing and enlightened steps that an enterprise can take to reduce security risks and protect their resources. We have also explained cloud computing strengths/benefits, weaknesses, and applicable areas in information risk management.

  18. Construct validity of the Concern For Appropriateness scale.

    Cutler, B L; Wolfe, R N

    1985-06-01

    Construct validity of the Concern For Appropriateness scale (CFA; Lennox & Wolfe, 1984), a measure of the tendency to adopt protective self-presentation styles, is examined using a multitrait-multimethod approach. Self-ratings on the CFA and ratings by suitemates constitute the two methods, and concern for appropriateness, interpersonal trust, and boredom susceptibility are assessed with each. Multitrait-multimethod analysis shows that the CFA scale exhibits convergent validity against peer ratings and discriminant validity against boredom susceptibility, the only other variable demonstrating convergence. Results indicate that the CFA exhibits construct validity and might therefore prove useful as an operationalization for self-presentation tendencies. PMID:16367476

  19. Hydraulic "fracking": are surface water impacts an ecological concern?

    Science.gov (United States)

    Burton, G Allen; Basu, Niladri; Ellis, Brian R; Kapo, Katherine E; Entrekin, Sally; Nadelhoffer, Knute

    2014-08-01

    Use of high-volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural gas and oil deposits to be recovered from shale formations. Millions of liters of local groundwaters are utilized to generate extensive fracture networks within these low-permeability reservoirs, allowing extraction of the trapped hydrocarbons. Although the technology is relatively standardized, the geographies and related policies and regulations guiding these operations vary markedly. Some ecosystems are more at risk from these operations than others because of either their sensitivities or the manner in which the HVHF operations are conducted. Generally, the closer geographical proximity of the susceptible ecosystem to a drilling site or a location of related industrial processes, the higher the risk of that ecosystem being impacted by the operation. The associated construction of roads, power grids, pipelines, well pads, and water-extraction systems along with increased truck traffic are common to virtually all HVHF operations. These operations may result in increased erosion and sedimentation, increased risk to aquatic ecosystems from chemical spills or runoff, habitat fragmentation, loss of stream riparian zones, altered biogeochemical cycling, and reduction of available surface and hyporheic water volumes because of withdrawal-induced lowering of local groundwater levels. The potential risks to surface waters from HVHF operations are similar in many ways to those resulting from agriculture, silviculture, mining, and urban development. Indeed, groundwater extraction associated with agriculture is perhaps a larger concern in the long term in some regions. Understanding the

  20. Managing nuclear knowledge: A SCK-CEN Concern

    International Nuclear Information System (INIS)

    Full text: Managing knowledge can be seen as the processes governing the creation, the dissemination and the utilisation of knowledge. Any organisation and specially a research centre will need a continuously updated body of knowledge as a basis of its sustained existence. Since its very beginning, SCK-CEN has always been a knowledge-based organisation aiming to solve topical problems based on experiences in the field, model-oriented experiments and fundamental research. Preserving and enhancing our institutional memory has become vital for the SCK-CEN. We are therefore pursuing our efforts to stimulating preservation and sharing of Nuclear Knowledge. Our knowledge exists in different forms and formats ranging from dispersed pieces of technical or scientific information on different media to a complex reservoir of people with the required educational background, expertise and acquired insights to apply that knowledge safely and effectively. SCK-CEN decided in 2001 to tackle this strategic concern by adopting a practical knowledge management (KM) approach. Our programme started in 2002 is built on 'what already exists'. KM activities were identified all over our organisation - building databases, assembling nuclear and technical information, implementing QA procedures, conducting training, writing publications - so that every researcher or technical staff can lay claim to it. However, a coordinated approach to Knowledge Management requires an efficient re-use of the recorded knowledge and an effective transfer of the available knowledge. This approach ensures an added value to our research work and guarantees on the long term the preservation of our institutional memory. The objective of the KM programme is the continuous improvement of the information management coupled with the elicitation of tacit knowledge, the stimulation of collaboration and the knowledge transfer. KM also enhances the information objects by adding or linking related additional information and

  1. Exploring domestic energy-saving: The role of environmental concern and background variables

    International Nuclear Information System (INIS)

    The main purpose of this paper is to investigate whether residents' environmental concern has any effect on their energy-saving curtailments and efficiency investments. The novelty of the present work lies in the fact that it seeks to investigate this topic in a multi-country setting, exploiting data from nine OECD countries (Australia, Canada, Czech Republic, France, Italy, South Korea, Netherlands, Norway and Sweden), and also in that it employs a latent variable model which allows us to examine the conditions necessary for the results to be comparable across different countries. Novel in this paper is also the focus on the role of environmental concern as a factor of several curtailments and efficiency investments. Our results suggest that people with higher environmental concern are on average more likely to perform energy-saving curtailments and also are more likely to have some energy-efficiency retrofits installed in dwellings. Most of the socio-economic and demographic variables have mixed effects on efficiency investments and curtailments. However, some interesting patterns emerged with respect to the age of respondents, household income, education and gender of respondents, and also the size of household. - Highlights: ► People with higher environmental concern are more likely to perform energy-saving curtailments. ► People with higher environmental concern are more likely to introduce some energy efficiency retrofits. ► Older people are more concerned about environmental problems, invest in efficiency and curtail more. ► Formal level of education does not play prominent role with respect to domestic energy-saving. ► Wealthier people are more likely to invest in energy efficiency but less likely to curtail.

    AIM: To document the concerns and expectations of parents of children with inflammatory bowel disease (IBD)within the context of a multidisciplinary IBD clinic, and to highlight the importance of a holistic approach to the care of these children.METHODS: The parents of 60 children with IBD were surveyed by mailed questionnaire. Parents were asked to provide details of their concerns regarding their child's condition and to express their expectations of medical care. In addition, enquiry was made in respect to the respondents' learning about IBD.RESULTS: Forty-six questionnaires (77%) returned. Fiftytwo percent of the patients were male. Patients were aged a mean of 10.9 (±4.1) years and diagnosed at an average age of 2.1 (±1.8) years previously. The most common concerns expressed by the parents related to the side- effects of medications and the future prospects for their child. Overall, parents were satisfied with aspects of care within the IBD clinic but many suggested additional personnel such as counselors or educators should be available. Parents also reported the need for continuing education and easy access to up-to-date information.CONCLUSION: Parents of children and adolescents with IBD have many common concerns regarding their child's condition. On-going attention to holistic care, including psychosocial and educational elements for patients and families, is appropriate in the context of the chronic and unpredictable nature of IBD.

    2015-10-01

    In 2014, a series of reforms, called as the Health Sector Evolution Plan (HSEP), was launched in the health system of Iran in a stepwise process. HSEP was mainly based on the fifth 5-year health development national strategies (2011-2016). It included different interventions to: increase population coverage of basic health insurance, increase quality of care in the Ministry of Health and Medical Education (MoHME) affiliated hospitals, reduce out-of-pocket (OOP) payments for inpatient services, increase quality of primary healthcare, launch updated relative value units (RVUs) of clinical services, and update tariffs to more realistic values. The reforms resulted in extensive social reaction and different professional feedback. The official monitoring program shows general public satisfaction. However, there are some concerns for sustainability of the programs and equity of financing. Securing financial sources and fairness of the financial contribution to the new programs are the main concerns of policy-makers. Healthcare providers' concerns (as powerful and influential stakeholders) potentially threat the sustainability and efficiency of HSEP. Previous experiences on extending health insurance coverage show that they can lead to a regressive healthcare financing and threat financial equity. To secure financial sources and to increase fairness, the contributions of people to new interventions should be progressive by their income and wealth. A specific progressive tax would be the best source, however, since it is not immediately feasible, a stepwise increase in the progressivity of financing must be followed. Technical concerns of healthcare providers (such as nonplausible RVUs for specific procedures or nonefficient insurance-provider processes) should be addressed through proper revision(s) while nontechnical concerns (which are derived from conflicting interests) must be responded through clarification and providing transparent information.

    The desire to achieve a normal, culturally acceptable body is often seen as the main driver of food-consumption practices adopted by individuals who are concerned about their body weight. In social research into weight management self-control is therefore often a central theme. Turning the focus...... towards practices and values related to food shopping, this study adds to our understanding of central features in perceptions of normality among people with weight concerns. In a qualitative study 25 people who participated in a dietary intervention trial in Denmark were interviewed and five people were...... observed. The study shows that the aim of achieving a normal body does not eclipse the importance of enacting values linked to ideas of the ‘normal consumer’. Using empirical examples, the study illuminates how consumer freedom is attained in ways that are both complementary to, and in conflict with...

  6. Energy decisions reframed as justice and ethical concerns

    Science.gov (United States)

    Sovacool, Benjamin K.; Heffron, Raphael J.; McCauley, Darren; Goldthau, Andreas

    2016-05-01

    All too often, energy policy and technology discussions are limited to the domains of engineering and economics. Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns. We conclude by proposing an energy justice framework centred on availability, affordability, due process, transparency and accountability, sustainability, equity and responsibility, which highlights the futurity, fairness and equity dimensions of energy production and use.

    1992-05-01

    Environmental health concerns in the Persian Gulf are peculiar to the geography of the region. Prevention of heat and solar injury deserves primary consideration, but cold injury also may occur in the desert. Immunizations are recommended against a number of diseases, while malarial chemoprophylaxis is necessary in Iraq and Kuwait. In addition to malaria, other parasitic diseases deserve consideration. Diarrheal diseases, diseases from the desert dust, and products of infected desert animals are of concern. Additional natural hazards are venomous bites from scorpions and desert snakes. Finally, threats of enemy action necessitated protection from nuclear biological and chemical weapons and LASER eye/skin injury. Unexploded ordinance will constitute a continuing hazard into the future. PMID:1495114

  8. Tainting the soul: purity concerns predict moral judgments of suicide.

    Science.gov (United States)

    Rottman, Joshua; Kelemen, Deborah; Young, Liane

    2014-02-01

    Moral violations are typically defined as actions that harm others. However, suicide is considered immoral even though the perpetrator is also the victim. To determine whether concerns about purity rather than harm predict moral condemnation of suicide, we presented American adults with obituaries describing suicide or homicide victims. While harm was the only variable predicting moral judgments of homicide, perceived harm (toward others, the self, or God) did not significantly account for variance in moral judgments of suicide. Instead, regardless of political and religious views and contrary to explicit beliefs about their own moral judgments, participants were more likely to morally condemn suicide if they (i) believed suicide tainted the victims' souls, (ii) reported greater concerns about purity in an independent questionnaire, (iii) experienced more disgust in response to the obituaries, or (iv) reported greater trait disgust. Thus, suicide is deemed immoral to the extent that it is considered impure.

    The nanoparticles are a miracle invention of the century that has opened novel avenues of applications in various fields. The safety aspect of exposure to nanoparticles for humans, plants, animals, soil micro-flora, and ecosystem at large has been questioned. The safety concern can be addressed by laboratory studies to assess the actual risk and recommend exposure limits and related regulation. There is also a suggestion for considering the nanoparticle form of conventional compounds as a new...

  11. Individual environmental concern in the world polity: A multilevel analysis.

    2013-03-01

    The authors assess the extent to which national-level integration in the world polity influences individual-level concern for the environment. While theoretically-derived propositions about such relationships have a deep history in comparative sociology, they-with few exceptions-remain untested. Consistent with past research, employed national-level measures of world polity integration include the relative presence of environmental international nongovernmental organizations (EINGOs) and the existence of environmental ministries. Results of multilevel analyses of individual-level environmental concern in 37 nations indicate that both forms of world polity integration increase the likelihood of individual-level environmental concern, net of other national-level factors and individual-level characteristics; although we find stronger support for the influence of EINGOs as a key variable indicating world polity connection. The findings provide unique support for world polity theory, suggesting that future research should consider how elements of world polity integration influence other forms of individual attitudes and behaviors. The results also highlight the importance in considering global and transnational factors when assessing the determinants of individual attitudes about the environment.

    Full Text Available The purpose of the paper was to establish and compare consumer preferences concerning the methods of fruit production (traditional or organic ones in the years 2001, 2003 and 2006 and the relations between the preferences and the socio-economic and demographic features of the consumers. The analysis was conducted on the basis of the data from surveys carried out among the inhabitants of Lublin. Results of those surveys point out that certain features of the consumers such as the sex, incomes and the family type significantly differentiated preferences concerning the method of fruit production. Increased incomes were connected with greater acceptance of the organic method, and their decrease was related to greater frequency of indicating the conventional method. Interest in the method of production, while buying the fruit was significantly higher among men than among women. Declaring the willingness to pay more for organic fruit was also correlated with the consumers’ sex. Besides, in 2006 it was not too strongly related to the incomes of the respondents. In the years 2001 and 2006 changeability of preferences con-cerning the willingness to pay a higher price for organic fruit and no change in the interest in the technology of fruit production while purchasing the fruit were shown.

Zika virus is enveloped and icosahedral, and has a nonsegmented, single-stranded, positive-sense RNA genome. It belongs to Flaviviridae family. Aedes aegypticus mosquito is the known vector. Transmission is anthroponotic (human to vector to human during outbreaks, or occurs perinatally in utero, sexually, and via transfusion of infected blood. Zika virus is turning out to be a major public health concern. Not only has it shown dramatic teratogenic association and caused serious neurological concerns but it has also spread around the globe. Countries that have not yet been affected by Zika virus should adopt proper preventive methods to limit its spread in the population.

    Perinatal depression is prevalent and linked with a host of adverse consequences for women and newborns. Rates of engagement in depression treatment are, however, strikingly low among pregnant and postpartum women, with the majority of affected women receiving no mental health treatment. Research indicates that perinatal women are extremely reluctant to take antidepressant medications, yet the nature of women's concerns and treatment decision- making patterns have not been well documented. Developing a clearer understanding of women's treatment preferences and behaviors may help identify solutions to the under-treatment of perinatal depression. In this mixed methods study, we conducted in-depth interviews with 61 pregnant women, approximately half of whom were experiencing clinical levels of depression. In addition to assessing psychiatric diagnoses, symptoms, and functional impairment, we conducted qualitative interviews addressing women's preferences for depression treatment, concerns, and decision-making patterns. Consistent with prior reports, women were significantly more likely to voice a preference for non-pharmacologic depression treatments, as opposed to antidepressant medications. Many depressed women reported a great degree of uncertainty regarding how to treat their depression, and those with more severe depression symptoms were more likely to endorse decisional conflict. Analysis of qualitative comments yielded detailed information about the nature of women's concerns and preferences related to use of antidepressant medications and other aspects of treatment engagement. We discuss findings in the context of improving patient-centered care for perinatal depression.

  15. Why Do You Believe in God? Relationships between Religious Belief, Analytic Thinking, Mentalizing and Moral Concern.

    Directory of Open Access Journals (Sweden)

    Anthony Ian Jack

    Full Text Available Prior work has established that analytic thinking is associated with disbelief in God, whereas religious and spiritual beliefs have been positively linked to social and emotional cognition. However, social and emotional cognition can be subdivided into a number of distinct dimensions, and some work suggests that analytic thinking is in tension with some aspects of social-emotional cognition. This leaves open two questions. First, is belief linked to social and emotional cognition in general, or a specific dimension in particular? Second, does the negative relationship between belief and analytic thinking still hold after relationships with social and emotional cognition are taken into account? We report eight hypothesis-driven studies which examine these questions. These studies are guided by a theoretical model which focuses on the distinct social and emotional processing deficits associated with autism spectrum disorders (mentalizing and psychopathy (moral concern. To our knowledge no other study has investigated both of these dimensions of social and emotion cognition alongside analytic thinking. We find that religious belief is robustly positively associated with moral concern (4 measures, and that at least part of the negative association between belief and analytic thinking (2 measures can be explained by a negative correlation between moral concern and analytic thinking. Using nine different measures of mentalizing, we found no evidence of a relationship between mentalizing and religious or spiritual belief. These findings challenge the theoretical view that religious and spiritual beliefs are linked to the perception of agency, and suggest that gender differences in religious belief can be explained by differences in moral concern. These findings are consistent with the opposing domains hypothesis, according to which brain areas associated with moral concern and analytic thinking are in tension.

    Full Text Available Mental models play an important role in the evolution of an individual's so-called knowledge. Using such representations, students can explain, foresee, and attribute causality to observed phenomena. In the case of Chemistry, the ability to work mentally with models assumes great importance, due to the microscopic component that is characteristic of this science. With the objective of exploring students' ability to work with models, 27 students of the Chemistry Institute of UNESP were asked to describe the mechanisms of dissolution, in water, of NaCl, HCl and HCN, as well as the partial dissolution of I2. Due to difficulties of access to complex descriptors of these processes, each student was asked to explain the phenomena using words and drawings. The results of these investigations were analyzed, and enabled construction of a framework representing the Chemistry students' theoretical training, especially with respect to their most important transferred skill: an ability to model the physical world.

    Full Text Available The environmental concern influences the purchase intention for green products in retail? In order to assess whether the consumer has intention to purchase green products for retail, in this study is investigated the influence of environmental concern on the buying behavior of the individual in the acquisition of green products at retail. Therefore, we performed an exploratory quantitative through a survey with a sample of 176 consumers residing in the southern city of São Paulo, answering about their perception about how he believes that other individuals of society respond to the same items. A scale was developed based on two previous studies. That scale was applied and validated for ten experts has proven effective for measuring environmental perception and purchase intention of the respondents. Data analysis was done by structural equation modeling, using the PLS measurement model. Results show that the consumer has intention to purchase green products for retail. However, not observed in the same proportion when it comes to its perception as a member of society, that is, the answers provided have a tendency for social desirability, ie, the consumer responds to the concern about being politically correct.

    This study investigated the perceptions on and adaptations to climate change impacts of 235 pangasius farmers in the Mekong Delta, Vietnam. Data were collected using semi-structured household surveys in six provinces, from three regions along the Mekong river branches. A Chi-Square test was used to determine the association between variables, and a logit regression model was employed to identify factors correlated with farmer's perception and adaptation. Less than half of respondents were concerned about climate change and sought suitable adaptation measures to alleviate its impacts. Improving information on climate change and introducing early warning systems could improve the adaptive capacity of pangasius farmers, in particularly for those farmers, who were not concerned yet. Farmers relied strongly on technical support from government agencies, but farmers in the coastal provinces did not express the need for training by these institutions. This contrasting result requires further assessment of the effectiveness of adaptation measures such as breeding salinity tolerant pangasius. PMID:25674502

    In the context of AD area consolidation activities a redesign of the AD-target is planned. The information presented in this report is a starting point to this purpose. The current design dates from late 80’s and it was obtained after more than 10 years of iterations and improvements of the material choices and conceptual designs due to the complexity of physical phenomena occurring inside the target material. The present report summarizes this process from the existing documents found in the literature as well as the inherent concerns which will have to be faced in the future design. Two major concerns which limit the target operation life were identified (i) shock wave effects and (ii) radiation damage. Therefore, a deep study of these phenomena and development of reliable models will be the way forward for the next steps in the re-design process.

    Wahid Murad, M. D.; Siwar, Chamhuri

    This study has developed three Logistic Regression Models to determine and analyze the factors that could affect knowledge, attitude and behavior of the urban poor concerning solid waste management. To pursue the objective, the study has collected primary data from the level of living conditions of the poor residing in the squatters and low-cost flats of Kuala Lumpur city, Malaysia. The empirical results of the study are exciting as they provide evidence to the effect that knowledge, attitude and behavior of the urban poor communities concerning solid waste management are adequate and satisfactory. Hence, the low socio-economic profile of the urban poor has not been proven as causal to environmental degradation. The study suggests that it is inherent to improve the quality of lifestyles of the poor to enable them to come out of poverty threshold, even though an adequate and satisfactory solid waste management system exists amongst the communities.

  2. Concerning the neutron level and the neutron RMS value in a linear feedback model of point reactor kinetics with one group of delayed neutrons and driven by random reactivity noise: application of the Runge-Kutta method to solve a system of stochastic ordinary differential equations

    International Nuclear Information System (INIS)

    A power noise model of point reactor kinetics with instantaneous negative reactivity feedback is considered. It is driven by stationary coloured Gaussian random reactivity noise. The model contains one group of delayed neutrons. They show partially destabilizing effects at intermediate power states. The neutron steady-state value and the neutron RMS value are obtained as functions of the reactivity excitation strength for different power states via computer simulation. The reactivity noise data are generated by a method based on the Rice formula, and the Langevin equations of the model are directly treated by the Runge-Kutta method. Results are compared with data obtainable from the Wieer-Hermite functional method in a first-order approximation

  3. Nuclear education and training: from concern to capability

    International Nuclear Information System (INIS)

    The OECD Nuclear Energy Agency (NEA) first published in 2000 Nuclear Education and Training: Cause for Concern?, which highlighted significant issues in the availability of human resources for the nuclear industry. Ten years on, Nuclear Education and Training: From Concern to Capability considers what has changed in that time and finds that, while some countries have taken positive actions, in a number of others human resources could soon be facing serious challenges in coping with existing and potential new nuclear facilities. This is exacerbated by the increasing rate of retirement as the workforce ages. This report provides a qualitative characterisation of human resource needs and appraises instruments and programmes in nuclear education and training initiated by various stakeholders in different countries. In this context, it also examines the current and future uses of nuclear research facilities for education and training purposes. Regarding the nuclear training component of workforce competence, it outlines a job taxonomy which could be a basis for addressing the needs of workers across this sector. It presents the taxonomy as a way of enhancing mutual recognition and increasing consistency of education and training for both developed and developing countries. Contents: 1 - A decade of change: Background; The evolving environment; A key resource - a competent workforce; 2 - Review of nuclear education and associated facilities: Introduction; Education and training - progress over the last decade; Present use of research infrastructure for education and training in NEA member countries; 3 - Towards a blueprint for workforce development: The benefits of a competent nuclear workforce; Classifying competence; Analysis ; 4 - Ensuring capability - the recommendations: Nuclear human resource features and requirements; Ten years on - the developments; Approach to developing a common job taxonomy; 5 - Appendices: Recommendations from Nuclear Education and Training

    The study investigated the views of graduate students on various environmental concerns. There were thirty (30) respondents, enrolled at Benguet State University of the Republic of the Philippines during the period March-May 2009, distributed as follows: nine for Master of Arts (MA) in Physics, two for MA General Science, fifteen for MA Mathematics, and four for MA Applied Statistics. There were ten males and twenty females. Likert-type responses for sixty-nine items were elicited through a questionnaire regarding levels of a) awareness, b) perceived knowledge, c) agreement, d) commitment, and e) expectations. Data analysis involved tests on means, based on the assumption that the responses were interval data. Results indicated that respondents lacked awareness about important national documents (such as Philippine Agenda 21 and Philippine Environment Code), perceived that they had a great knowledge of environmental topics (e.g., climate change and global warming), agreed to various environmental issues (involving balance of nature and sustainable development, among others), held a strong commitment to do action (especially in terms of integrating environmental education with their classes, if they were teachers), and held great expectations of the University's roles as an Organic Agriculture University (such as integrating environmental concerns in the curriculum, or introducing adaptation strategies for dealing with environmental problems, among others). In general, the respondents held similar perceptions, whether grouped according to sex or degree program. The major implication is that the MA Physics program, like the other three, can be a fertile ground for the inclusion of environmental concerns, towards the goal of producing solutions for both local and global challenges.

    Full Text Available In this paper we made an analysis of the loyalty in the auto market. We selected a sample from the residents of Craiova and asked them about their intentions concerning satisfaction, repurchase and recommendation regarding their cars. We used as auto market as the base of our study, since the car industry is very attractive to customers. We documented some correlation among the three dimensions of the loyalty. At the applicative level we found out that the loyalty toward the German cars is much higher than the loyalty for the cars from other countries. Further studies are needed to investigate the complex dimensions of the loyalty in-depth.

    Increased use of hydraulic fracturing ("fracking") in unconventional oil and natural gas (O & NG) development from coal, sandstone, and shale deposits in the United States (US) has created environmental concerns over water and air quality impacts. In this perspective we focus on how the production of unconventional O & NG affects air quality. We pay particular attention to shale gas as this type of development has transformed natural gas production in the US and is set to become important in the rest of the world. A variety of potential emission sources can be spread over tens of thousands of acres of a production area and this complicates assessment of local and regional air quality impacts. We outline upstream activities including drilling, completion and production. After contrasting the context for development activities in the US and Europe we explore the use of inventories for determining air emissions. Location and scale of analysis is important, as O & NG production emissions in some US basins account for nearly 100% of the pollution burden, whereas in other basins these activities make up less than 10% of total air emissions. While emission inventories are beneficial to quantifying air emissions from a particular source category, they do have limitations when determining air quality impacts from a large area. Air monitoring is essential, not only to validate inventories, but also to measure impacts. We describe the use of measurements, including ground-based mobile monitoring, network stations, airborne, and satellite platforms for measuring air quality impacts. We identify nitrogen oxides, volatile organic compounds (VOC), ozone, hazardous air pollutants (HAP), and methane as pollutants of concern related to O & NG activities. These pollutants can contribute to air quality concerns and they may be regulated in ambient air, due to human health or climate forcing concerns. Close to well pads, emissions are concentrated and exposure to a wide range of

    Free-living amoebae are the most likely protozoa implicated in health concerns of the indoor environment. These amoebae can be the source of allergic reactions, eye infections or, on rare occasions, encephalitis. While too large to be effectively aerosolized, free- living amoebae can support the multiplication of pathogens such as Legionella which are easily aerosolized and infectious via the pulmonary route. Traditional detection methods for free-living amoebae are laborious and time consuming. Newer techniques for rapidly detecting and quantitating free-living amoebae such as monoclonal antibodies, flow cytometry, gene probes, and laser optics have or could be employed. 25 refs.

    It is likely that the complex law concerning alcohol and drugs in the workplace is one of the reasons for unwillingness to resolve the problem of intake of such psychoactive substances by employees. 'Iherefore, the author made an attempt to depict Polish legislation in this field based on the review of legal acts and regulations, as well as on their extensive judiciary interpretation. Such an information can be used by employers in developing their workplace policy of diminishing the intake of psychoactive substances by employees. This information can also be helpful for the bodies supporting workplaces in solving problems derived from alcohol and drugs consumption, such as occupational medicine specialists and local governments.

    Blindness from retinopathy of prematurity (ROP) in Australian and New Zealand is an uncommon event although 3% of oxygen saturation targeting trial results might mean the adoption of higher targets than formerly in very preterm infants and will require vigilance to ensure all eligible infants are examined appropriately. A true screening examination for acute ROP might involve non-opthalmologists obtaining photographic retinal images and remote reading of these. Although treatment with laser gives good outcomes, there is interest in intravitreal anti-vascular endothelial factor agents, but issues concerning the systemic safety and retinal results of such treatment are unresolved.

  17. Altering Visual Perception Abnormalities: A Marker for Body Image Concern.

    Directory of Open Access Journals (Sweden)

    Francesca L Beilharz

    Full Text Available The body image concern (BIC continuum ranges from a healthy and positive body image, to clinical diagnoses of abnormal body image, like body dysmorphic disorder (BDD. BDD and non-clinical, yet high-BIC participants have demonstrated a local visual processing bias, characterised by reduced inversion effects. To examine whether this bias is a potential marker of BDD, the visual processing of individuals across the entire BIC continuum was examined. Dysmorphic Concern Questionnaire (DCQ; quantified BIC scores were expected to correlate with higher discrimination accuracy and faster reaction times of inverted stimuli, indicating reduced inversion effects (occurring due to increased local visual processing. Additionally, an induced global or local processing bias via Navon stimulus presentation was expected to alter these associations. Seventy-four participants completed the DCQ and upright-inverted face and body stimulus discrimination task. Moderate positive associations were revealed between DCQ scores and accuracy rates for inverted face and body stimuli, indicating a graded local bias accompanying increases in BIC. This relationship supports a local processing bias as a marker for BDD, which has significant assessment implications. Furthermore, a moderate negative relationship was found between DCQ score and inverted face accuracy after inducing global processing, indicating the processing bias can temporarily be reversed in high BIC individuals. Navon stimuli were successfully able to alter the visual processing of individuals across the BIC continuum, which has important implications for treating BDD.

  18. Parvovirus transmission by blood products - a cause for concern?

    Science.gov (United States)

    Norja, Päivi; Lassila, Riitta; Makris, Mike

    2012-11-01

    The introduction of dual viral inactivation of clotting factor concentrates has practically eliminated infections by viruses associated with significant pathogenicity over the last 20 years. Despite this, theoretical concerns about transmission of infection have remained, as it is known that currently available viral inactivation methods are unable to eliminate parvovirus B19 or prions from these products. Recently, concern has been raised following the identification of the new parvoviruses, human parvovirus 4 (PARV4) and new genotypes of parvovirus B19, in blood products. Parvoviruses do not cause chronic pathogenicity similar to human immunodeficiency virus or hepatitis C virus, but nevertheless may cause clinical manifestations, especially in immunosuppressed patients. Manufacturers should institute measures, such as minipool polymerase chain reaction testing, to ensure that their products contain no known viruses. So far, human bocavirus, another new genus of parvovirus, has not been detected in fractionated blood products, and unless their presence can be demonstrated, routine testing during manufacture is not essential. Continued surveillance of the patients and of the safety of blood products remains an important ongoing issue.

  19. Ultimate concerns in late modernity: Archer, Bourdieu and reflexivity.

    Science.gov (United States)

    Farrugia, David; Woodman, Dan

    2015-12-01

    Through a critique of Margaret Archer's theory of reflexivity, this paper explores the theoretical contribution of a Bourdieusian sociology of the subject for understanding social change. Archer's theory of reflexivity holds that conscious 'internal conversations' are the motor of society, central both to human subjectivity and to the 'reflexive imperative' of late modernity. This is established through critiques of Bourdieu, who is held to erase creativity and meaningful personal investments from subjectivity, and late modernity is depicted as a time when a 'situational logic of opportunity' renders embodied dispositions and the reproduction of symbolic advantages obsolete. Maintaining Archer's focus on 'ultimate concerns' in a context of social change, this paper argues that her theory of reflexivity is established through a narrow misreading and rejection of Bourdieu's work, which ultimately creates problems for her own approach. Archer's rejection of any pre-reflexive dimensions to subjectivity and social action leaves her unable to sociologically explain the genesis of 'ultimate concerns', and creates an empirically dubious narrative of the consequences of social change. Through a focus on Archer's concept of 'fractured reflexivity', the paper explores the theoretical necessity of habitus and illusio for understanding the social changes that Archer is grappling with. In late modernity, reflexivity is valorized just as the conditions for its successful operation are increasingly foreclosed, creating 'fractured reflexivity' emblematic of the complex contemporary interaction between habitus, illusio, and accelerating social change.

  20. Health and fracking: should the medical profession be concerned?

    Mash, Rachel; Minnaar, Jolynn; Mash, Bob

    2014-05-01

    The use of natural gas that is obtained from high-volume hydraulic fracturing (fracking) may reduce carbon emissions relative to the use of coal and have substantial economic benefits for South Africa. However, concerns have been raised regarding the health and environmental impacts. The drilling and fracking processes use hundreds of chemicals as well as silica sand. Additional elements are either released from or formed in the shale during drilling. These substances can enter the environment in various ways: through failures in the well casing; via alternative underground pathways; as wastewater, spills and leaks on the wellpad; through transportation accidents; and as air pollution. Although many of these chemicals and elements have known adverse health effects, there is little evidence available on the health impacts of fracking. These health concerns have not yet been fully addressed in policy making, and the authors recommend that the voice of health professionals should be part of the public debate on fracking and that a full health impact assessment be required before companies are given the go-ahead to drill.  PMID:25212197
