Targeting CPS1 in the treatment of Carbamoyl phosphate synthetase 1 (CPS1) deficiency, a urea cycle disorder.

Diez-Fernandez, Carmen; Häberle, Johannes

2017-04-01

Carbamoyl phosphate synthetase 1 (CPS1) deficiency (CPS1D) is a rare autosomal recessive urea cycle disorder (UCD), which can lead to life-threatening hyperammonemia. Unless promptly treated, it can result in encephalopathy, coma and death, or intellectual disability in surviving patients. Over recent decades, therapies for CPS1D have barely improved leaving the management of these patients largely unchanged. Additionally, in many cases, current management (protein-restriction and supplementation with citrulline and/or arginine and ammonia scavengers) is insufficient for achieving metabolic stability, highlighting the importance of developing alternative therapeutic approaches. Areas covered: After describing UCDs and CPS1D, we give an overview of the structure- function of CPS1. We then describe current management and potential novel treatments including N-carbamoyl-L-glutamate (NCG), pharmacological chaperones, and gene therapy to treat hyperammonemia. Expert opinion: Probably, the first novel CPS1D therapies to reach the clinics will be the already commercial substance NCG, which is the standard treatment for N-acetylglutamate synthase deficiency and has been proven to rescue specific CPS1D mutations. Pharmacological chaperones and gene therapy are under development too, but these two technologies still have key challenges to be overcome. In addition, current experimental therapies will hopefully add further treatment options.

Fluid Ability (Gf and Complex Problem Solving (CPS

2017-07-01

Full Text Available Complex problem solving (CPS has emerged over the past several decades as an important construct in education and in the workforce. We examine the relationship between CPS and general fluid ability (Gf both conceptually and empirically. A review of definitions of the two factors, prototypical tasks, and the information processing analyses of performance on those tasks suggest considerable conceptual overlap. We review three definitions of CPS: a general definition emerging from the human problem solving literature; a more specialized definition from the “German School” emphasizing performance in many-variable microworlds, with high domain-knowledge requirements; and a third definition based on performance in Minimal Complex Systems (MCS, with fewer variables and reduced knowledge requirements. We find a correlation of 0.86 between expert ratings of the importance of CPS and Gf across 691 occupations in the O*NET database. We find evidence that employers value both Gf and CPS skills, but CPS skills more highly, even after controlling for the importance of domain knowledge. We suggest that this may be due to CPS requiring not just cognitive ability but additionally skill in applying that ability in domains. We suggest that a fruitful future direction is to explore the importance of domain knowledge in CPS.

We present a new transformation of call-by-value lambdaterms into continuation-passing style (CPS). This transformation operates in one pass and is both compositional and first-order. Because it operates in one pass, it directly yields compact CPS programs that are comparable to what one would...... write by hand. Because it is compositional, it allows proofs by structural induction. Because it is first-order, reasoning about it does not require the use of a logical relation. This new CPS transformation connects two separate lines of research.

SVM-Based Dynamic Reconfiguration CPS for Manufacturing System in Industry 4.0

Directory of Open Access Journals (Sweden)

Hyun-Jun Shin

2018-01-01

Full Text Available CPS is potential application in various fields, such as medical, healthcare, energy, transportation, and defense, as well as Industry 4.0 in Germany. Although studies on the equipment aging and prediction of problem have been done by combining CPS with Industry 4.0, such studies were based on small numbers and majority of the papers focused primarily on CPS methodology. Therefore, it is necessary to study active self-protection to enable self-management functions, such as self-healing by applying CPS in shop-floor. In this paper, we have proposed modeling of shop-floor and a dynamic reconfigurable CPS scheme that can predict the occurrence of anomalies and self-protection in the model. For this purpose, SVM was used as a machine learning technology and it was possible to restrain overloading in manufacturing process. In addition, we design CPS framework based on machine learning for Industry 4.0, simulate it, and perform. Simulation results show the simulation model autonomously detects the abnormal situation and it is dynamically reconfigured through self-healing.

In order to supplement defects of paper procedure, reduce human errors and enhance convenient operation, computer-based procedure system is being developed. CPS (Computerized Procedure System) including human-factor engineering design concept for KNGR (Korean Next Generation Reactor) has been also developed with the same object. K-CPS(KNGR CPS) has higher level of automation than paper procedure. It is fully integrated with control and monitoring systems. Combining statements and relevant components, which changes dynamically according to plant status enhances readability of procedure. This paper shows general design criteria on computer-based procedure system, the MMI design characteristics of K-CPS and the results of suitability evaluation for K-CPS by operator

Phylogenetic distribution and membrane topology of the LytR-CpsA-Psr protein family

Berger-Bächi Brigitte

2008-12-01

Full Text Available Abstract Background The bacterial cell wall is the target of many antibiotics and cell envelope constituents are critical to host-pathogen interactions. To combat resistance development and virulence, a detailed knowledge of the individual factors involved is essential. Members of the LytR-CpsA-Psr family of cell envelope-associated attenuators are relevant for β-lactam resistance, biofilm formation, and stress tolerance, and they are suggested to play a role in cell wall maintenance. However, their precise function is still unknown. This study addresses the occurrence as well as sequence-based characteristics of the LytR-CpsA-Psr proteins. Results A comprehensive list of LytR-CpsA-Psr proteins was established, and their phylogenetic distribution and clustering into subgroups was determined. LytR-CpsA-Psr proteins were present in all Gram-positive organisms, except for the cell wall-deficient Mollicutes and one strain of the Clostridiales. In contrast, the majority of Gram-negatives did not contain LytR-CpsA-Psr family members. Despite high sequence divergence, the LytR-CpsA-Psr domains of different subclusters shared a highly similar, predicted mixed a/β-structure, and conserved charged residues. PhoA fusion experiments, using MsrR of Staphylococcus aureus, confirmed membrane topology predictions and extracellular location of its LytR-CpsA-Psr domain. Conclusion The LytR-CpsA-Psr domain is unique to bacteria. The presence of diverse subgroups within the LytR-CpsA-Psr family might indicate functional differences, and could explain variations in phenotypes of respective mutants reported. The identified conserved structural elements and amino acids are likely to be important for the function of the domain and will help to guide future studies of the LytR-CpsA-Psr proteins.

Automated glycan assembly of a S. pneumoniae serotype 3 CPS antigen

Full Text Available Vaccines against S. pneumoniae, one of the most prevalent bacterial infections causing severe disease, rely on isolated capsular polysaccharide (CPS that are conjugated to proteins. Such isolates contain a heterogeneous oligosaccharide mixture of different chain lengths and frame shifts. Access to defined synthetic S. pneumoniae CPS structures is desirable. Known syntheses of S. pneumoniae serotype 3 CPS rely on a time-consuming and low-yielding late-stage oxidation step, or use disaccharide building blocks which limits variability. Herein, we report the first iterative automated glycan assembly (AGA of a conjugation-ready S. pneumoniae serotype 3 CPS trisaccharide. This oligosaccharide was assembled using a novel glucuronic acid building block to circumvent the need for a late-stage oxidation. The introduction of a washing step with the activator prior to each glycosylation cycle greatly increased the yields by neutralizing any residual base from deprotection steps in the synthetic cycle. This process improvement is applicable to AGA of many other oligosaccharides.

SLAE-CPS: Smart Lean Automation Engine Enabled by Cyber-Physical Systems Technologies.

In the context of Industry 4.0, the demand for the mass production of highly customized products will lead to complex products and an increasing demand for production system flexibility. Simply implementing lean production-based human-centered production or high automation to improve system flexibility is insufficient. Currently, lean automation (Jidoka) that utilizes cyber-physical systems (CPS) is considered a cost-efficient and effective approach for improving system flexibility under shrinking global economic conditions. Therefore, a smart lean automation engine enabled by CPS technologies (SLAE-CPS), which is based on an analysis of Jidoka functions and the smart capacity of CPS technologies, is proposed in this study to provide an integrated and standardized approach to design and implement a CPS-based smart Jidoka system. A set of comprehensive architecture and standardized key technologies should be presented to achieve the above-mentioned goal. Therefore, a distributed architecture that joins service-oriented architecture, agent, function block (FB), cloud, and Internet of things is proposed to support the flexible configuration, deployment, and performance of SLAE-CPS. Then, several standardized key techniques are proposed under this architecture. The first one is for converting heterogeneous physical data into uniform services for subsequent abnormality analysis and detection. The second one is a set of Jidoka scene rules, which is abstracted based on the analysis of the operator, machine, material, quality, and other factors in different time dimensions. These Jidoka rules can support executive FBs in performing different Jidoka functions. Finally, supported by the integrated and standardized approach of our proposed engine, a case study is conducted to verify the current research results. The proposed SLAE-CPS can serve as an important reference value for combining the benefits of innovative technology and proper methodology.

This paper describes the Japan Meteorological Agency/Meteorological Research Institute-Coupled Prediction System version 2 (JMA/MRI-CPS2), which was put into operation in June 2015 for the purpose of performing seasonal predictions. JMA/MRI-CPS2 has various upgrades from its predecessor, JMA/MRI-CPS1, including improved resolution and physics in its atmospheric and oceanic components, introduction of an interactive sea-ice model and realistic initialization of its land component. Verification of extensive re-forecasts covering a 30-year period (1981-2010) demonstrates that JMA/MRI-CPS2 possesses improved seasonal predictive skills for both atmospheric and oceanic interannual variability as well as key coupled variability such as the El Niño-Southern Oscillation (ENSO). For ENSO prediction, the new system better represents the forecast uncertainty and transition/duration of ENSO phases. Our analysis suggests that the enhanced predictive skills are attributable to incremental improvements resulting from all of the changes, as is apparent in the beneficial effects of sea-ice coupling and land initialization on 2-m temperature predictions. JMA/MRI-CPS2 is capable of reasonably representing the seasonal cycle and secular trends of sea ice. The sea-ice coupling remarkably enhances the predictive capability for the Arctic 2-m temperature, indicating the importance of this factor, particularly for seasonal predictions in the Arctic region.

Role of Ontologies for CPS Implementation in Manufacturing

Directory of Open Access Journals (Sweden)

Garetti Marco

2015-12-01

Full Text Available Cyber Physical Systems are an evolution of embedded systems featuring a tight combination of collaborating computational elements that control physical entities. CPSs promise a great potential of innovation in many areas including manufacturing and production. This is because we obtain a very powerful, flexible, modular infrastructure allowing easy (re configurability and fast ramp-up of manufacturing applications by building a manufacturing system with modular mechatronic components (for machining, transportation and storage and embedded intelligence, by integrating them into a system, through a network connection. However, when building such kind of architectures, the way to supply the needed domain knowledge to real manufacturing applications arises as a problem to solve. In fact, a CPS based architecture for manufacturing is made of smart but independent manufacturing components without any knowledge of the role they have to play together in the real world of manufacturing applications. Ontologies can supply such kind of knowledge, playing a very important role in CPS for manufacturing. The paper deals with this intriguing theme, also presenting an implementation of this approach in a research project for the open automation of manufacturing systems, in which the power of CPS is complemented by the support of an ontology of the manufacturing domain.

Blockchain-Oriented Coalition Formation by CPS Resources: Ontological Approach and Case Study

Directory of Open Access Journals (Sweden)

Alexey Kashevnik

2018-05-01

Full Text Available Cyber-physical systems (CPS, robotics, Internet of Things, information and communication technologies have become more and more popular over the last several years. These topics open new perspectives and scenarios that can automate processes in human life. CPS are aimed at interaction support in information space for physical entities communicated in physical space in real time. At the same time the blockchain technology that becomes popular last years allows to organize immutable distributed database that store all significant information and provide access for CPS participants. The paper proposes an approach that is based on ontology-based context management, publish/subscribe semantic interoperability support, and blockchain techniques. Utilization of these techniques provide possibilities to develop CPS that supports dynamic, distributed, and stable coalition formation of the resources. The case study presented has been implemented for the scenario of heterogeneous mobile robots’ collaboration for the overcoming of obstacles. There are two types of robots and an information service participating in the scenario. Evaluation shows that the proposed approach is applicable for the presented class of scenarios.

Streptococcus iniae cpsG alters capsular carbohydrate composition and is a cause of serotype switching in vaccinated fish.

Heath, Candice; Gillen, Christine M; Chrysanthopoulos, Panagiotis; Walker, Mark J; Barnes, Andrew C

2016-09-25

Streptococcus iniae causes septicaemia and meningitis in marine and freshwater fish wherever they are farmed in warm-temperate and tropical regions. Although serotype specific, vaccination with bacterins (killed bacterial cultures) is largely successful and vaccine failure occurs only occasionally through emergence of new capsular serotypes. Previously we showed that mutations in vaccine escapes are restricted to a limited repertoire of genes within the 20-gene capsular polysaccharide (cps) operon. cpsG, a putative UDP-galactose 4-epimerase, has three sequence types based on the insertion or deletion of the three amino acids leucine, serine and lysine in the substrate binding site of the protein. To elucidate the role of cpsG in capsular polysaccharide (CPS) biosynthesis and capsular composition, we first prepared isogenic knockout and complemented mutants of cpsG by allelic exchange mutagenesis. Deletion of cpsG resulted in changes to colony morphology and cell buoyant density, and also significantly decreased galactose content relative to glucose in the capsular polysaccharide as determined by GC-MS, consistent with epimerase activity of CpsG. There was also a metabolic penalty of cpsG knockout revealed by slower growth in complex media, and reduced proliferation in whole fish blood. Moreover, whilst antibodies raised in fish against the wild type cross-reacted in whole cell and cps ELISA, they did not cross-opsonise the mutant in a peripheral blood neutrophil opsonisation assay, consistent with reported vaccine escape. We have shown here that mutation in cpsG results in altered CPS composition and this in turn results in poor cross-opsonisation that explains some of the historic vaccination failure on fish farms in Australia.

2017-01-01

Full Text Available Access security and privacy have become a bottleneck for the popularization of future Cyber-Physical System (CPS networks. Furthermore, users’ need for privacy-preserved access during movement procedure is more urgent. To address the anonymous access authentication issue for CPS Wireless Mesh Network (CPS-WMN, a novel anonymous access authentication scheme based on proxy ring signature is proposed. A hierarchical authentication architecture is presented first. The scheme is then achieved from the aspect of intergroup and intragroup anonymous mutual authentication through proxy ring signature mechanism and certificateless signature mechanism, respectively. We present a formal security proof of the proposed protocol with SVO logic. The simulation and performance analysis demonstrate that the proposed scheme owns higher efficiency and adaptability than the typical one.

Highlights: • The main parameters of tritium generation and release from lithium capillary-porous system (CPS) under neutron irradiation at the IVG.1 M research reactor is described in paper. • In the experiments a very small tritium release was fixed likely due to its high solubility in liquid lithium. • If the lithium CPS will be used as a plasma facing material in temperature range up to 773 K under neutron irradiation only helium will release from lithium CPS into a vacuum chamber. - Abstract: This paper describes the main parameters of tritium generation and release from lithium capillary-porous system (CPS) under neutron irradiation at the IVG.1 M research reactor. The experiments were carried out using the method of mass-spectrometric registration of released gases and using a specially constructed ampoule device. Irradiation was carried out at different reactor thermal powers (1, 2 and 6 MW) and sample temperatures from 473 to 773 K. In the experiments a very small tritium release was detected likely due to its high solubility in liquid lithium. It can be caused by formation of lithium tritide during tritium diffusion to the lithium surface.

Diffusive Promotion by Velocity Gradient of Cytoplasmic Streaming (CPS in Nitella Internodal Cells.

Directory of Open Access Journals (Sweden)

Kenji Kikuchi

Full Text Available Cytoplasmic streaming (CPS is well known to assist the movement of nutrients, organelles and genetic material by transporting all of the cytoplasmic contents of a cell. CPS is generated by motility organelles that are driven by motor proteins near a membrane surface, where the CPS has been found to have a flat velocity profile in the flow field according to the sliding theory. There is a consistent mixing of contents inside the cell by CPS if the velocity gradient profile is flattened, which is not assisted by advection diffusion but is only supported by Brownian diffusion. Although the precise flow structure of the cytoplasm has an important role for cellular metabolism, the hydrodynamic mechanism of its convection has not been clarified. We conducted an experiment to visualise the flow of cytoplasm in Nitella cells by injecting tracer fluorescent nanoparticles and using a flow visualisation system in order to understand how the flow profile affects their metabolic system. We determined that the velocity field in the cytosol has an obvious velocity gradient, not a flattened gradient, which suggests that the gradient assists cytosolic mixing by Taylor-Aris dispersion more than by Brownian diffusion.

To simultaneously quantify and profile the complex mixture of short-, median-, and long-chain CPs (SCCPs, MCCPs, and LCCPs) in Australian sewage sludge, we applied and further validated a recently developed novel instrumental technique, using quadrupole time-of-flight high resolution mass spectrometry running in the negative atmospheric pressure chemical ionization mode (APCI-qTOF-HRMS). Without using an analytical column the cleaned extracts were directly injected into the qTOF-HRMS followed by quantification of the CPs by a mathematical algorithm. The recoveries of the four SCCP, MCCP and LCCP-spiked sewage sludge samples ranged from 86 to 123%. This APCI-qTOF-HRMS method is a fast and promising technique for routinely measuring SCCPs, MCCPs, and LCCPs in sewage sludge. Australian sewage sludge was dominated by MCCPs with concentrations ranging from 542 to 3645 ng/g dry weight (dw). Lower SCCPs concentrations (<57-1421 ng/g dw) were detected in the Australian sewage sludge, which were comparable with the LCCPs concentrations (116-960 ng/g dw). This is the first time that CPs were reported in Australian sewage sludge. The results of this study gives a first impression on the distribution of the SCCPs, MCCPs, and LCCPs in Australia wastewater treatment plants (WWTPs).

How social processes distort measurement: the impact of survey nonresponse on estimates of volunteer work in the United States.

Abraham, Katharine G; Presser, Stanley; Helms, Sara

2009-01-01

The authors argue that both the large variability in survey estimates of volunteering and the fact that survey estimates do not show the secular decline common to other social capital measures are caused by the greater propensity of those who do volunteer work to respond to surveys. Analyses of the American Time Use Survey (ATUS)--the sample for which is drawn from the Current Population Survey (CPS)--together with the CPS volunteering supplement show that CPS respondents who become ATUS respondents report much more volunteering in the CPS than those who become ATUS nonrespondents. This difference is replicated within subgroups. Consequently, conventional adjustments for nonresponse cannot correct the bias. Although nonresponse leads to estimates of volunteer activity that are too high, it generally does not affect inferences about the characteristics of volunteers.

2003-01-01

At present, at the Ignalina NPP the process of a wider use of the new uranium-erbium fuel of higher saturation and the manual control rods of new design is going on. These actions are directed to reducing the reactor control and protection system (CPS) cooling circuit voiding effect and to improving the technical and economical reactor operation parameters. Continuous withdrawal and falling out of CPS control rods lead to the reactivity and power changes in the reactor core. Therefore, important for safety is the evaluation of the CPS ability to compensate for the resulting excess reactivity in the reactor core, having the changed core loading conditions during such accidents. This article presents the calculation results of the continuous withdrawal and falling out of CPS control rods for the specific reactor core conditions of the Ignalina NPP Unit 2, i.e. during its operation on the maximum allowed power level of 4200 MW. The German code QUABOX/CUBBOX-HYCA with the improved CPS logic was used for the simulation of the above-mentioned transients. (author)

Representative national surveys in dwellings are important to unbiasedly evaluate the exposure of the general population to radon. In Italy, a representative national survey was conducted from 1989 to 1996, which involved about 5600 dwellings in 232 towns. Later on, some Regions carried out more detailed surveys, but a new national survey in dwellings is necessary in order to obtain a more thorough estimate of radon concentration distribution over the Italian territory. The need to make this survey in an affordable way led to implement a new approach based on the collaboration between the Istituto Superiore di Sanità and a national company with workplaces and employees' homes throughout the country. The intent is to carry out a proxy of a population representative survey by measuring radon concentration in the homes of a random sample of the company employees. The realisation of this survey was affordable, thanks to the availability of corporate e-mail for each employee, intranet service, and company internal mail service. A dedicated web procedure and e-questionnaires allowed to automatically manage the contact with employees and to collect their data, which were both cost- and time-saving. Using this e-mail contact approach, 53% of contacted employees consented to participate in the survey. Radon concentration passive measuring devices were distributed to about 7000 dwellings, using about 14000 CR-39 detectors (two measured rooms per dwelling). In order to reduce costs, the devices were exposed for 12 months instead of two consecutive 6-month periods (as with the former national survey). A first checking of the actual representativeness of the sample was done by comparing characteristics of dwellings and occupants in the sample with corresponding data from the latest National Census. This was accomplished thanks to the fact that the questions in the survey questionnaire were tailored to the categories adopted for the Census questionnaire. A preliminary

2017-01-01

Palliative sedation can be used for refractory symptoms during end-of-life care. However, continuous palliative sedation (CPS) for existential distress remains controversial due to difficulty determining when this distress is refractory. The aim was to determine the opinions and practices of Canadian palliative care physicians regarding CPS for existential distress. A survey focusing on experience and views regarding CPS for existential distress was sent to 322 members of the Canadian Society of Palliative Care Physicians. Eighty-one surveys returned (accessible target, 314), resulting in a response rate of 26%. One third (31%) of the respondents reported providing CPS for existential distress. On a 5-point Likert-type scale, 40% of participants disagreed, while 43% agreed that CPS could be used for existential distress alone. Differing opinions exist regarding this complex and potentially controversial issue, necessitating the education of health-care professionals and increased awareness within the general public.

In consequence of activities on uncovering the reasons for through faults formation in cooling tubes of reactor control and protection system (CPS) channels of Bilibino-2 reactor the conclusion is made that corrosion failure development takes place against the backdrop of periodic increase of total moisture in reactor space at transient and standby modes at top of cooling tubes of CPS channels. Formation of corrosion defects in cooling tubes of four CPS channels of unit 2 in 2011-2012 is specific factor for this plant unit and do not effect on operation of other plant units. It is pointed out that ingress of moisture into gas system of the reactor is the critical factor providing integrity of structure elements of EhPG-6 reactor core cooling system. This fact agrees nicely with the results obtained during operation AM reactor of the First NPP [ru

Scalp psoriasis is a difficult to treat and usually chronic manifestation of psoriasis. The CalePso study showed that CPS (Clobex(®) Shampoo) in maintenance therapy of scalp psoriasis (twice weekly) significantly increases the probability of keeping patient under remission during 6 months, compared with vehicle (40.3% relapses vs. 11.6% relapses, ITT). The objective of the study was to assess the cost-effectiveness of a maintenance therapy with CPS vs. its vehicle in nine European countries. A 24-week decision tree model was developed with 4-weekly time steps. The considered population has moderate scalp psoriasis successfully treated with a daily application of CPS up to 4 weeks. Data were taken from the CalePso study and from national experts' recommendations for alternative treatment choices, with their probabilities of success taken from literature to develop country-specific models. Health benefits are measured in disease-free days (DFD). The economic analysis includes drug and physician costs. A probabilistic sensitivity analysis (PrSA) assesses the uncertainty of the model. Depending on the country, the mean total number of DFDs per patient is 21-42% higher with CPS compared with vehicle, and the mean total cost is 11-31% lower. The mean costs per DFD are 30-46% lower with CPS compared with the vehicle. The PrSA showed in 1000 simulations that CPS is more effective vs. vehicle in 100% of the cases and less expensive than its vehicle in 80-99% of the cases. This model suggests that CPS is cost-effective in maintaining the success achieved in moderate scalp psoriasis patients. © 2011 The Authors.

Although virulence of Streptococcus pneumoniae is associated with its capsule, some pathogenic S. pneumoniae isolates lack capsules and are serologically nontypeable (NT). We obtained 64 isolates that were identified as NT "pneumococci" (i.e., bacteria satisfying the conventional definition but without the multilocus sequence typing [MLST]-based definition of S. pneumoniae) by the traditional criteria. All 64 were optochin sensitive and had lytA, and 63 had ply. Twelve isolates had cpsA, suggesting the presence of a conventional but defective capsular polysaccharide synthesis (cps) locus. The 52 cpsA-negative isolates could be divided into three null capsule clades (NCC) based on aliC (aliB-like ORF1), aliD (aliB-like ORF2), and our newly discovered gene, pspK, in their cps loci. pspK encodes a protein with a long alpha-helical region containing an LPxTG motif and a YPT motif known to bind human pIgR. There were nine isolates in NCC1 (pspK(+) but negative for aliC and aliD), 32 isolates in NCC2 (aliC(+) aliD(+) but negative for pspK), and 11 in NCC3 (aliD(+) but negative for aliC and pspK). Among 52 cpsA-negative isolates, 41 were identified as S. pneumoniae by MLST analysis. All NCC1 and most NCC2 isolates were S. pneumoniae, whereas all nine NCC3 and two NCC2 isolates were not S. pneumoniae. Several NCC1 and NCC2 isolates from multiple individuals had identical MLST and cps regions, showing that unencapsulated S. pneumoniae can be infectious among humans. Furthermore, NCC1 and NCC2 S. pneumoniae isolates could colonize mice as well as encapsulated S. pneumoniae, although S. pneumoniae with an artificially disrupted cps locus did not. Moreover, an NCC1 isolate with pspK deletion did not colonize mice, suggesting that pspK is critical for colonization. Thus, PspK may provide pneumococci a means of surviving in the nasopharynx without capsule. IMPORTANCE The presence of a capsule is critical for many pathogenic bacteria, including pneumococci.

Blob formation and transport is a major concern for investigators as it greatly reduces the efficiency of the devices. Initial results from CPS device confirm the role of fast neutrals inside the bulk plasma in the process of blob formation and transport. 2-D simulation of curvature and velocity shear instability in plasma structures suggest that in the presence of background plasma, secondary instability do not grow non-linearly to a high level and stabilizes the flow. Adiabaticity effect also creates a radial barrier for interchange modes. In the absence of background plasma the blob fragments even at the modest level of viscosity. The fast neutrals outside bulk plasma supposed to stabilize the system. The background plasma set up is aimed at creating fast neutrals outside main plasma column, hence; the background plasma set up is done in CPS device. The spatial behavior of plasma column in between electrodes is different for different base pressure in CPS device. The spatial variation of electron temperature of plasma column between electrodes is presented in this communication. Electron temperature is measured from emission spectroscopy data. The maximum electron temperature (line averaged) is ∼ 1.5 eV. (author)

Objective  To examine whether the increase in use of electronic cigarettes in the USA, which became noticeable around 2010 and increased dramatically by 2014, was associated with a change in overall smoking cessation rate at the population level. Design  Population surveys with nationally representative samples. Setting  Five of the US Current Population Survey-Tobacco Use Supplement (CPS-TUS) in 2001-02, 2003, 2006-07, 2010-11, and 2014-15. Participants  Data on e-cigarette use were obtained from the total sample of the 2014-15 CPS-TUS (n=161 054). Smoking cessation rates were obtained from those who reported smoking cigarettes 12 months before the survey (n=23 270). Rates from 2014-15 CPS-TUS were then compared with those from 2010-11 CPS-TUS (n=27 280) and those from three other previous surveys. Main outcome measures  Rate of attempt to quit cigarette smoking and the rate of successfully quitting smoking, defined as having quit smoking for at least three months. Results  Of 161 054 respondents to the 2014-15 survey, 22 548 were current smokers and 2136 recent quitters. Among them, 38.2% of current smokers and 49.3% of recent quitters had tried e-cigarettes, and 11.5% and 19.0% used them currently (every day or some days). E-cigarette users were more likely than non-users to attempt to quit smoking, 65.1% v 40.1% (change=25.0%, 95% confidence interval 23.2% to 26.9%), and more likely to succeed in quitting, 8.2% v 4.8% (3.5%, 2.5% to 4.5%). The overall population cessation rate for 2014-15 was significantly higher than that for 2010-11, 5.6% v 4.5% (1.1%, 0.6% to 1.5%), and higher than those for all other survey years (range 4.3-4.5%). Conclusion  The substantial increase in e-cigarette use among US adult smokers was associated with a statistically significant increase in the smoking cessation rate at the population level. These findings need to be weighed carefully in regulatory policy making regarding e-cigarettes and in planning tobacco

Shen, Jiajun; Feng, Dongqin

2018-03-01

In this paper, the cross-layer security problem of cyber-physical system (CPS) is investigated from the game-theoretic perspective. Physical dynamics of plant is captured by stochastic differential game with cyber-physical influence being considered. The sufficient and necessary condition for the existence of state-feedback equilibrium strategies is given. The attack-defence cyber interactions are formulated by a Stackelberg game intertwined with stochastic differential game in physical layer. The condition such that the Stackelberg equilibrium being unique and the corresponding analytical solutions are both provided. An algorithm is proposed for obtaining hierarchical security strategy by solving coupled games, which ensures the operational normalcy and cyber security of CPS subject to uncertain disturbance and unexpected cyberattacks. Simulation results are given to show the effectiveness and performance of the proposed algorithm.

However, the expression of TUSC3 in hepatocellular carcinoma (HCC tissues remains ambiguous. The purpose of this research was to investigate the expression of TUSC3 in HCC tissues and analyze the relationship between TUSC3 levels and clinicopathological characteristics and prognosis of HCC patients. Materials and methods: Immunohistochemistry was used to detect the expression of TUSC3 in HCC and the corresponding para-cancerous tissues from 92 samples of HCC patients. mRNA and protein expression levels of TUSC3 were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR and Western blot assays in 25 paired HCC and corresponding adjacent nontumor tissues. Furthermore, statistical analysis was applied to evaluate the correlation between TUSC3 level and the clinicopathological features and prognosis of HCC patients. Results: Immunohistochemical assay indicated that the expression of TUSC3 was significantly lower in HCC tissues when compared with the corresponding para-cancerous tissues (χ2=11.512, P=0.001. The analysis of clinicopathological characteristics showed that low expression of TUSC3 in HCC tissues was significantly associated with Edmondson grade, Barcelona Clinic Liver Cancer stage and tumor size (P=0.008, 0.009 and 0.020, respectively.

Population-representative surveys that assess childhood maltreatment and health are a valuable resource to explore the implications of child maltreatment for population health. Systematic identification and evaluation of such surveys is needed to facilitate optimal use of their data and to inform future research. To inform researchers of the existence and nature of population-representative surveys relevant to understanding links between childhood maltreatment and health; to evaluate the assessment of childhood maltreatment in this body of work. We included surveys that: 1) were representative of the non-institutionalized population of any size nation or of any geopolitical region ≥ 10 million people; 2) included a broad age range (≥ 40 years); 3) measured health; 4) assessed childhood maltreatment retrospectively; and 5) were conducted since 1990. We used Internet and database searching (including CINAHL, Embase, ERIC, Global Health, MEDLINE, PsycINFO, Scopus, Social Policy and Practice: January 1990 to March 2014), expert consultation, and other means to identify surveys and associated documentation. Translations of non-English survey content were verified by fluent readers of survey languages. We developed checklists to abstract and evaluate childhood maltreatment content. Fifty-four surveys from 39 countries met inclusion criteria. Sample sizes ranged from 1,287-51,945 and response rates from 15%-96%. Thirteen surveys assessed neglect, 15 emotional abuse; 18 exposure to family violence; 26 physical abuse; 48 sexual abuse. Fourteen surveys assessed more than three types; six of these were conducted since 2010. In nine surveys childhood maltreatment assessments were detailed (+10 items for at least one type of maltreatment). Seven surveys' assessments had known reliability and/or validity. Data from 54 surveys can be used to explore the population health relevance of child maltreatment. Assessment of childhood maltreatment is not comprehensive but there is

The study aims to identify community pharmacists' (CPs) utilization of information and communication technology (ICT); to develop and characterize a typology of CPs' utilization of ICT and to identify factors that can enhance or inhibit the use of these technologies. An online survey of the 7649 members of the Pharmacist Association of Barcelona who had a registered email account in 2006 was carried out. Factor analysis, cluster analysis and binomial logit modelling were undertaken. Multivariate analysis of the CPs' responses to the survey (648) revealed two profiles of adoption of ICT. The first profile (40.75%) represents those CPs who place high emphasis on ICT within their practice. This group is therefore referred to as 'integrated CPs'. The second profile (59.25%) represents those CPs who make less use of ICT and so are consequently labelled 'non-integrated CPs'. Statistical modelling was used to identify variables that were important in predisposing CPs to integrate ICT with their work. From the analysis it is evident that responses to questions relating to 'recommend patients going on line for health information'; 'patients discuss or share their Internet health information findings'; 'emphasis on the Internet for communication and dissemination' and 'Pharmacists Professional Association information' play a positive and significant role in the probability of being an 'integrated CP'. The integration of ICT within CPs' practices cannot be adequately understood and appreciated without examining how CPs are making use of ICT within their own practice, their organizational context and the nature of the pharmacists-client relationship.

Total synthesis of a Streptococcus pneumoniae serotype 12F CPS repeating unit hexasaccharide

Full Text Available The Gram-positive bacterium Streptococcus pneumoniae causes severe disease globally. Vaccines that prevent S. pneumoniae infections induce antibodies against epitopes within the bacterial capsular polysaccharide (CPS. A better immunological understanding of the epitopes that protect from bacterial infection requires defined oligosaccharides obtained by total synthesis. The key to the synthesis of the S. pneumoniae serotype 12F CPS hexasaccharide repeating unit that is not contained in currently used glycoconjugate vaccines is the assembly of the trisaccharide β-D-GalpNAc-(1→4-[α-D-Glcp-(1→3]-β-D-ManpNAcA, in which the branching points are equipped with orthogonal protecting groups. A linear approach relying on the sequential assembly of monosaccharide building blocks proved superior to a convergent [3 + 3] strategy that was not successful due to steric constraints. The synthetic hexasaccharide is the starting point for further immunological investigations.

The Classroom Performance System (CPS) is an instructional technology tool that increases student performance and addresses different learning styles. Instructional technologies are used to promote active learning; however, student embarrassment issue in a multicultural setting is not addressed. This study assessed the effect of the CPS on student participation, attendance, and achievement in multicultural college-level anatomy and physiology classes at South Texas College, where the first spoken language is not English. Quantitative method and quasi-experimental design were employed and comparative statistic methods and pre-post tests were used to collect the data. Participants were college students and sections of study were selected by convenient sampling. Participation was 100% during most of the lectures held and participation rate did not strike above 68% in control group. Attendance was significantly higher in CPS sections than the control group as shown by t-tests. Experimental sections had a higher increase in the pre-post test scores and student averages on lecture exams increased at a higher rate as compared to the control group. Therefore, the CPS increased student participation, attendance, and achievement in multicultural anatomy and physiology classes. The CPS can be studied in other settings where the first spoken language is English or in other programs, such as special education programs. Additionally, other variables can be studied and other methodologies can be employed.

The crystallization is reported of two bacterial tyrosine phosphatases which belong to different enzyme families despite their ability to catalyse identical reactions. Bacterial tyrosine kinases and their cognate phosphatases are key players in the regulation of capsule assembly and thus are important virulence determinants of these bacteria. Examples of the kinase/phosphatase pairing are found in Gram-negative bacteria such as Escherichia coli (Wzc and Wzb) and in Gram-positive bacteria such as Streptococcus pneumoniae (CpsCD and CpsB). Although Wzb and Cps4B are both predicted to dephosphorylate the C-terminal tyrosine cluster of their cognate tyrosine kinase, they appear on the basis of protein sequence to belong to quite different enzyme classes. Recombinant purified proteins Cps4B of S. pneumoniae TIGR4 and Wzb of E. coli K-30 have been crystallized. Wzb crystals belonged to space-group family P3 x 21 and diffracted to 2.7 Å resolution. Crystal form I of Cps4B belonged to space-group family P4 x 2 1 2 and diffracted to 2.8 Å resolution; crystal form II belonged to space group P2 1 2 1 2 1 and diffracted to 1.9 Å resolution

With the rapid development of cyber-physical systems (CPS), building cyber-physical systems with high quality of service (QoS) has become an urgent requirement in both academia and industry. During the procedure of building Cyber-physical systems, it has been found that a large number of functionally equivalent services exist, so it becomes an urgent task to recommend suitable services from the large number of services available in CPS. However, since it is time-consuming, and even impractical, for a single user to invoke all of the services in CPS to experience their QoS, a robust QoS prediction method is needed to predict unknown QoS values. A commonly used method in QoS prediction is collaborative filtering, however, it is hard to deal with the data sparsity and cold start problem, and meanwhile most of the existing methods ignore the data credibility issue. Thence, in order to solve both of these challenging problems, in this paper, we design a framework of QoS prediction for CPS services, and propose a personalized QoS prediction approach based on reputation and location-aware collaborative filtering. Our approach first calculates the reputation of users by using the Dirichlet probability distribution, so as to identify untrusted users and process their unreliable data, and then it digs out the geographic neighborhood in three levels to improve the similarity calculation of users and services. Finally, the data from geographical neighbors of users and services are fused to predict the unknown QoS values. The experiments using real datasets show that our proposed approach outperforms other existing methods in terms of accuracy, efficiency, and robustness.

We developed a quantitative method for attaining a representative sample during sampling survey of RI waste. Considering a source, process, and type of RI waste, the method computes the number of sample, confidence interval, variance, and coefficient of variance. We also systematize the method of sampling survey logically and quantitatively. The result of this study can be applied to sampling survey of low- and intermediate-level waste generated from nuclear power plant during the transfer process to disposal facility.

Pathologic complete response after neoadjuvant chemotherapy (NACT) correlates with overall survival (OS) in primary breast cancer. A recently described staging system based on pre-treatment clinical stage (CS), final pathological stage (PS), estrogen receptor (ER) status and nuclear grade (NG) leads to a refined estimation of prognosis in unselected patients. Its performance in luminal type breast cancers has not been determined. This study investigates the clinical utility of this CPS+EG score when restricted to hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) patients and compares the results to a cohort of unselected patients. The CPS+EG score was calculated for 6637 unselected patients and 2454 patients with HR+/HER2- tumours who received anthracycline/taxane-based NACT within 8 prospective German trials. Five-year disease-free survival (DFS) and OS were 75.6% and 84.1% for the unselected cohort and 80.6% and 87.8% for the HR+/HER2- subgroup, respectively. The CPS+EG system distinguished different prognostic groups with 5-year DFS ranging from 0% to 91%. The CPS+EG system leads to an improved categorisation of patients by outcome compared to CS, PS, ER or NG alone. When applying the CPS+EG score to the HR+/HER2- subgroup, a shift to lower scores was observed compared to the overall population, but 5-year DFS and OS for the individual scores were identical to that observed in the overall population. In HR+/HER2- patients, the CPS+EG staging system retains its ability to facilitate a refined stratification of patients according to outcome. It can help to select candidates for post-neoadjuvant clinical trials in luminal breast cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

Environmental airborn radioactivity survey around Burg El Arab Area, Western desert, Egypt

An environmental airborne radioactivity survey of approximately 250 square kilometres of Burg El Arab area was conducted by the Airborne Geophysical survey Division of the Geology and Raw Materials Department. The environmental levels of gamma radiation are measured so as to determine quickly the amount and extent of any possible future increase in radioactivity levels of the area by the proposed nuclear facility through normal operations or any accident that may occur. The aerial radiometric measurements were obtained by a continuously recording airborne scintillometer type RVS-1. installed in an Antonoff-2 aircraft, flying at an average speed of 170 Km/h, at a nominal ground clearance of 50 m. The survey was carried out along 84 parallel flight lines directed N-S, and spaced 250 m apart. The area is shown on the geological map as composed of four lithological units. The analysis of the data has proved that these units correspond to six distinct levels of characteristic radioactivity, as two of the lithological units could each be separated into two radioactivity levels on the basis of the radioactivity pattern. The six radiometric levels are, from north to south, beach limy sediments (15 to 101. and 97 to 191 cps), detrital limestone (201 to 354 cpt), saline lakes and salt deposits (262 to 444 cps), and alluvial deposits (307 to 308 and 412 to 742 cps)

The number of medical studies performed through online surveys has increased dramatically in recent years. Despite their numerous advantages (eg, sample size, facilitated access to individuals presenting stigmatizing issues), selection bias may exist in online surveys. However, evidence on the representativeness of self-selected samples in online studies is patchy. Our objective was to explore the representativeness of a self-selected sample of online gamers using online players' virtual characters (avatars). All avatars belonged to individuals playing World of Warcraft (WoW), currently the most widely used online game. Avatars' characteristics were defined using various games' scores, reported on the WoW's official website, and two self-selected samples from previous studies were compared with a randomly selected sample of avatars. We used scores linked to 1240 avatars (762 from the self-selected samples and 478 from the random sample). The two self-selected samples of avatars had higher scores on most of the assessed variables (except for guild membership and exploration). Furthermore, some guilds were overrepresented in the self-selected samples. Our results suggest that more proficient players or players more involved in the game may be more likely to participate in online surveys. Caution is needed in the interpretation of studies based on online surveys that used a self-selection recruitment procedure. Epidemiological evidence on the reduced representativeness of sample of online surveys is warranted.

Full text: Compartment-NT syndrom (CPS) of the legs is considered to have an ischaemic basis related to muscle swelling and pressure increase in a muscle compartment (MC) during isotonic work. We decided to study selected patients where CPS was suspected with exercise 201 TI SPECT of the legs to better define their diagnoses. Eighteen patients with probable CPS reproduced their leg pain(s) during isotonic work, and 100 MBq of 201 TI was given i.v. during continued work and pain. Anterior 300 sec. planar and 360 degree, elliptical SPECT studies were acquired five minutes after stress and again four hours later. Quantitation of whole calf and regional MC uptake was attempted after the first five patients were assessed qualitatively. Ten patients were men and eight were women. The mean age was 30.8 y. Four had localised posterior and three had anterior pain with 11 having mixed and bilateral symptoms. Five patients had had a bone scan in the past and nine had MC pressure studies done within a month of study. Six patients had had previous decompressive surgery and seven patients had surgery after stress/rest studies. Four asymptomatic cardiac patients (''controls'') were imaged after their cardiac 201 TI studies and data used for comparison. Mean age of controls was 33 years. Generally even muscle uptake was seen on stress images with mean washout of 201 TI of 12% (7-23%) being calculated on delayed images of controls. Painful MCs with qualitative reduction in uptake after stress showed a mean increase in 201 TI of 25.7% (6-39%) on delayed imaging. Three patients with dramatic improvement in symptoms after surgery had shown a mean increase of 25.2% in delayed uptake in MCs on pre-operative studies. One patient showed washout of 11 and 15% from posterior MCs and had a poor response to subsequent surgery. Further clinical follow up in a large group of patients will be required to fully identify the place of Stress 201 TI imaging of the legs in this difficult group of

In the United Kingdom, pharmaceutical services can be delivered by both community pharmacies (CPs) and dispensing doctor practices (DPs). Both must adhere to minimum standards set out in NHS regulations; however, no common framework exists to guide quality improvement. Previous phases of this research had developed a set of characteristics indicative of good pharmaceutical service provision. To ask key stakeholders to confirm, and rank the importance of, a set of characteristics of good pharmaceutical service provision. A two-round Delphi-type survey was conducted in south-west England and was sent to participants representing three stakeholder groups: DPs, CPs and patients/lay members. Participants were asked to confirm, and rank, the importance of these characteristics as representing good quality pharmaceutical services. Thirty people were sent the first round survey; 22 participants completed both rounds. Median ratings for the 23 characteristics showed that all were seen to represent important aspects of pharmaceutical service provision. Participants' comments highlighted potential problems with the practicality of the characteristics. Characteristics relating to patient safety were deemed to be the most important and those relating to public health the least important. A set of 23 characteristics for providing good pharmaceutical services in CPs and DPs was developed and attained approval from a sample of stakeholders. With further testing and wider discussion, it is hoped that the characteristics will form the basis of a quality improvement tool for CPs and DPs. © 2016 Royal Pharmaceutical Society.

The initial search identified 2776 surveys that were further screened for language, location, year, sample size, survey structure and representativeness. 44 surveys that passed the screening process were accessed and their codebooks were examined to see whether the two questions of interest were included. Eight datasets allowed extraction or estimation of relevant information. Survey quality was assessed with regards to response rates, sampling methods and data collection procedures. PRISMA guidelines were followed, with explicit rules for approaching derived variables and skip patterns. Proportions were pooled using random effects meta-analysis. The eight surveys used representative samples of the general adult population. Response rates varied from 45% to 88%. Survey methods were on par with the best practice in this field. Altogether 216,314 respondents were included of whom 60.3% (95%CI 51.3-69.3) ever tried a cigarette. Among those, 68.9% (95% CI 60.9-76.9%) progressed to daily smoking. Over two thirds of people who try one cigarette become, at least temporarily, daily smokers. The finding provides strong support for the current efforts to reduce cigarette experimentation among adolescents. The transition from trying the first cigarette through occasional to daily smoking usually implies that a recreational activity is turning into a compulsive need that has to be satisfied virtually continuously. The 'conversion rate' from initial experimentation to daily smoking is thus a potentially important metric of smoking behavior, but estimates of it based on

This exploratory study examines combinations of income-tested welfare benefits and earnings, as they relate to the likelihood of child maltreatment investigations among low-income families with young children participating in a nutritional assistance program in one U.S. state (Wisconsin). Using a sample of 1065 parents who received the Special Supplemental Nutrition Assistance Program for Women, Infants, and Children (WIC) benefits in late 2010 and early 2011, we find that relying on either work in the absence of other means-tested welfare benefits, or a combination of work and welfare benefits, reduces the likelihood of CPS involvement compared to parents who rely on welfare benefits in the absence of work. Additionally, we find that housing instability increases the risk of CPS involvement in this population. The findings from this investigation may be useful to programs serving low-income families with young children, as they attempt to identify safety net resources for their clientele.

Women with metastatic breast cancer (MBC) face numerous, complex treatment and advance care planning (ACP) decisions. Our aim was to develop a better understanding of women with MBC's decision-making preferences overtime and relative to specific types of decisions. Convergent, parallel mixed-methods study. Participants completed the Control Preferences Scale (CPS) and a semi-structured interview of decision-making experiences at enrollment (T1; n=22) and when facing a decision or 3 months later (T2; n=19). We categorized women's decision-making experience descriptions into one of the CPS decisional styles and compared them to their CPS response. We constructed an analytic grid that aligned the interview-determined treatment and ACP decisional preferences with the CPS categories at T1 and T2 and calculated Cohen's kappa coefficient and congruence percentages. Participants (n=22) were White (100%), averaged 62 years, married (54%), retired (45%), and had a bachelor's degree (45%). Congruence between CPS response and interview-determined treatment preferences at T1 was 32% (kappa=0.083) and 33% (kappa=0.120) at T2. Congruence between CPS survey response and interview-determined ACP preferences at T1 was 22.7% (kappa =0.092) at T1 and 11% (kappa = 0.011) at T2. Although women selected a "shared" treatment decision-making style using the CPS validated tool, when interviewed their descriptions generally reflected a passive process in which they followed the oncologists' treatment suggestions. Future research should explore whether the incongruence between stated and actual decision-making style is a function of misinterpreting the CPS choices or a true inconsistency that could lead to adverse consequences such as decisional regret.

Hussain, S.; Davis, T.

2012-12-01

Static and dynamic reservoir characterization was done on high resolution P-wave seismic data in Delhi Field, LA to study the complex stratigraphy of the Holt-Bryant sands and to delineate the CO2 flow path. The field is undergoing CO2 injection for enhanced oil recovery. The seismic data was bandwidth extended by Geotrace to decrease the tuning thickness effect. Once the authenticity of the added frequencies in the data was determined, the interpretation helped map thin Tuscaloosa and Paluxy sands. Cross-equalization was done on the baseline and monitor surveys to remove the non-repeatable noise in the data. Acoustic impedance (AI) inversion was done on the baseline and monitor surveys to map the changes in AI with CO2 injection in the field. Figure 1 shows the AI percentage change at Base Paluxy. The analysis helped identify areas that were not being swept by CO2. Figure 2 shows the CO2 flow paths in Tuscaloosa formation. The percentage change of AI with CO2 injection and pressure increase corresponded with the fluid substitution modeling results. Time-lapse interpretation helped in delineating the channels, high permeability zones and the bypassed zones in the reservoir.; Figure 1: P-impedance percentage difference map with a 2 ms window centered at the base of Paluxy with the production data from June 2010 overlain; the black dashed line is the oil-water contact; notice the negative impedance change below the OWC.

Interaction of valleys and circulation patterns (CPs on spatial precipitation patterns in southern Germany

Directory of Open Access Journals (Sweden)

M. Liu

2013-11-01

Full Text Available Topography exerts influence on the spatial precipitation distribution over different scales, known typically at the large scale as the orographic effect, and at the small scale as the wind-drift rainfall (WDR effect. At the intermediate scale (1~10 km, which is characterized by secondary mountain valleys, topography also demonstrates some effect on the precipitation pattern. This paper investigates such intermediate-scale topographic effects on precipitation patterns, focusing on narrow-steep valleys in the complex terrain of southern Germany, based on the daily observations over a 48 yr period (1960~2007 from a high-density rain-gauge network covering two sub-areas, Baden-Wuerttemberg (BW and Bavaria (BY. Precipitation data at the valley and non-valley stations are compared under consideration of the daily general circulation patterns (CPs classified by a fuzzy rule-based algorithm. Scatter plots of precipitation against elevation demonstrate a different behavior of valley stations comparing to non-valley stations. A detailed study of the precipitation time series for selected station triplets, each consisting of a valley station, a mountain station and an open station have been investigated by statistical analysis with the Kolmogorov–Smirnov (KS test supplemented by the One-way analysis of variance (One-way ANOVA and a graphical comparison of the mean precipitation amounts. The results show an interaction of valley orientation and the direction of the CPs at the intermediate scale, i.e. when the valley is shielded from the CP which carries the precipitation, the precipitation amount within the valley is comparable to that on the mountain crest, and both larger than the precipitation at the open station. When the valley is open to the CP, the precipitation within the valley is similar to the open station but much less than that on the mountain. Such phenomenon where the precipitation is "blind" to the valleys at the intermediate scale

2010-04-01

Addressing the risks of nanoparticles requires knowledge about release into the environment and occupational exposure. However, such information currently is not systematically collected; therefore, this risk assessment lacks quantitative data. The goal was to evaluate the current level of nanoparticle usage in Swiss industry as well as health, safety, and environmental measures, and the number of potentially exposed workers. A representative, stratified mail survey was conducted among 1626 clients of the Swiss National Accident Insurance Fund (SUVA), which insures 80,000 manufacturing firms, representing 84% of all Swiss manufacturing companies (947 companies answered the survey for a 58.3% response rate). The extrapolation to all Swiss manufacturing companies results in 1309 workers (95% confidence interval [CI]: 1073 to 1545) potentially exposed to nanoparticles in 586 companies (95% CI: 145 to 1027). This corresponds to 0.08% of workers (95% CI: 0.06% to 0.09%) and to 0.6% of companies (95% CI: 0.2% to 1.1%). The industrial chemistry sector showed the highest percentage of companies using nanoparticles (21.2%). Other important sectors also reported nanoparticles. Personal protection equipment was the predominant protection strategy. Only a few applied specific environmental protection measures. This is the first nationwide representative study on nanoparticle use in the manufacturing sector. The information gained can be used for quantitative risk assessment. It can also help policymakers design strategies to support companies developing a safer use of nanomaterial. Noting the current low use of nanoparticles, there is still time to proactively introduce protective methods. If the predicted "nano-revolution" comes true, now is the time to take action.

The Impact of Survey and Response Modes on Current Smoking Prevalence Estimates Using TUS-CPS: 1992-2003

Directory of Open Access Journals (Sweden)

Julia Soulakova

2009-12-01

Full Text Available This study identified whether survey administration mode (telephone or in-person and respondent type (self or proxy result in discrepant prevalence of current smoking in the adult U.S. population, while controlling for key sociodemographic characteristics and longitudinal changes of smoking prevalence over the 11-year period from 1992-2003. We used a multiple logistic regression analysis with replicate weights to model the current smoking status logit as a function of a number of covariates. The final model included individual- and family-level sociodemographic characteristics, survey attributes, and multiple two-way interactions of survey mode and respondent type with other covariates. The respondent type is a significant predictor of current smoking prevalence and the magnitude of the difference depends on the age, sex, and education of the person whose smoking status is being reported. Furthermore, the survey mode has significant interactions with survey year, sex, and age. We conclude that using an overall unadjusted estimate of the current smoking prevalence may result in underestimating the current smoking rate when conducting proxy or telephone interviews especially for some sub-populations, such as young adults. We propose that estimates could be improved if more detailed information regarding the respondent type and survey administration mode characteristics were considered in addition to commonly used survey year and sociodemographic characteristics. This information is critical given that future surveillance is moving toward more complex designs. Thus, adjustment of estimates should be contemplated when comparing current smoking prevalence results within a given survey series with major changes in methodology over time and between different surveys using various modes and respondent types.

This document presents results of a survey comprising a qualitative survey among residents at the vicinity of wind farms, a quantitative survey among the same kind of residents and among a sample representing the French population older than 18, and a qualitative survey among elected representatives of local communities. Graphs illustrate results in terms of opinion on wind energies, of relationship between information and confidence in a wind farm project. Three sets of residents living everyday at the vicinity of wind farms are synthesised in terms of opinion: the convinced ones, the unconcerned ones, and the upset ones. The opinions in terms of impacts (income for local communities and for farmers, the proof of a commitment for a virtuous ecological policy, a way to impulse a dynamics, or local curiosity) are also assessed. The main levers for a higher acceptance of wind farms are identified

Campylobacter jejuni NCTC12662 is sensitive to infection by many Campylobacter bacteriophages. Here we used this strain to investigate the molecular mechanism behind phage resistance development when exposed to a single phage and demonstrate how phase variable expression of one surface component...... influences phage sensitivity against many diverse C. jejuni phages. When C. jejuni NCTC12662 was exposed to phage F207 overnight, 25% of the bacterial cells were able to grow on a lawn of phage F207, suggesting that resistance develops at a high frequency. One resistant variant, 12662R, was further...... characterized and shown to be an adsorption mutant. Plaque assays using our large phage collection showed that seven out of 36 diverse capsular polysaccharide (CPS)-dependent phages could not infect 12662R, whereas the remaining phages formed plaques on 12662R with reduced efficiencies.

High-energy coordination polymers (CPs) not only exhibit good energetic performances but also have a good catalytic effect on the thermal decomposition of energetic materials. In this contribution, two high-energy CPs Cu2(DNBT)2(CH3OH)(H2O)3·3H2O (1) and [Cu3(DDT)2(H2O)2]n (2) (H2DNBT = 3,3‧-dinitro-5,5‧-bis(1H-1,2,4-triazole and H3DDT = 4,5-bis(1H-tetrazol-5-yl)-2H-1,2,3-triazole) were synthesized and structurally characterized. Furthermore, 1 was thermos-dehydrated to produce Cu2(DNBT)2(CH3OH)(H2O)3 (1a). The thermal decomposition kinetics of 1, 1a and 2 were studied by Kissinger's method and Ozawa's method. Thermal analyses and sensitivity tests show that all compounds exhibit high thermal stability and low sensitivity for external stimuli. Meanwhile, all compounds have large positive enthalpy of formation, which are calculated as being (1067.67 ± 2.62) kJ mol-1 (1), (1464.12 ± 3.12) kJ mol-1 (1a) and (3877.82 ± 2.75) kJ mol-1 (2), respectively. The catalytic effects of 1a and 2 on the thermal decomposition of ammonium dinitramide (ADN) were also investigated.

Measurement of sexual health in the U.S.: an inventory of nationally representative surveys and surveillance systems.

Science.gov (United States)

Ivankovich, Megan B; Leichliter, Jami S; Douglas, John M

2013-01-01

To identify opportunities within nationally representative surveys and surveillance systems to measure indicators of sexual health, we reviewed and inventoried existing data systems that include variables relevant to sexual health. We searched for U.S. nationally representative surveys and surveillance systems that provided individual-level sexual health data. We assessed the methods of each data system and catalogued them by their measurement of the following domains of sexual health: knowledge, communication, attitudes, service access and utilization, sexual behaviors, relationships, and adverse health outcomes. We identified 18 U.S.-focused, nationally representative data systems: six assessing the general population, seven focused on special populations, and five addressing health outcomes. While these data systems provide a rich repository of information from which to assess national measures of sexual health, they present several limitations. Most importantly, apart from data on service utilization, routinely gathered, national data are currently focused primarily on negative aspects of sexual health (e.g., risk behaviors and adverse health outcomes) rather than more positive attributes (e.g., healthy communication and attitudes, and relationship quality). Nationally representative data systems provide opportunities to measure a broad array of domains of sexual health. However, current measurement gaps indicate the need to modify existing surveys, where feasible and appropriate, and develop new tools to include additional indicators that address positive domains of sexual health of the U.S. population across the life span. Such data can inform the development of effective policy actions, services, prevention programs, and resource allocation to advance sexual health.

2016-03-01

Evaluate the efficacy of a child passenger safety (CPS) educational intervention on the CPS-related knowledge, attitude and anticipatory guidance behaviors of pediatric interns. All subjects were surveyed at baseline and 6 months. Intervention interns attended a CPS training module which included viewing an educational video, observing a car seat inspection appointment, hands-on practice and completion of a post-intervention survey. All 16 intervention interns completed the initial survey, the intervention and the immediate-post questionnaire. Thirteen (81%) completed the 6-month follow-up. The baseline survey was completed by 27/40 (67%) of control interns, 28/40 (70%) submitted a follow-up. The proportion of intervention interns who self-reported giving CPS guidance at all well-child visits increased by 31.3% (95% CI 6.1,56.5%); the control group had no change. Similar results were seen with self-reported knowledge and attitude. A CPS training module increases pediatric interns' knowledge, improves attitudes, and self-reported behaviors regarding CPS-related anticipatory guidance.

Spirituality and religiosity in psychotherapy--a representative survey among German psychotherapists.

Science.gov (United States)

Hofmann, Liane; Walach, Harald

2011-03-01

We report a survey in a near-representative sample of 895 German psychotherapists. Fifty-seven percent of the respondents referred to themselves as either spiritual or religious. Psychotherapists estimated that on average 22% of their patients bring in topics around spirituality and religion during the course of therapy. Two-thirds thought that topics around spirituality and religion should be part of the postgraduate and/or graduate curriculum. There was a clear difference between therapeutic orientations regarding how they felt about such issues, with CBT and psychodynamically oriented therapists placing less emphasis on spiritual issues and integrative and humanistic therapists more. However, differences between schools were less important than commonalities. We conclude that spirituality and religiosity are important topics for training and further research.

Japanese practicing physicians' relationships with pharmaceutical representatives: a national survey.

Directory of Open Access Journals (Sweden)

Sayaka Saito

Full Text Available BACKGROUND: Previous surveys on the relationship between physicians and pharmaceutical representatives (PRs have been of limited quality. The purpose of our survey of practicing physicians in Japan was to assess the extent of their involvement in pharmaceutical promotional activities, physician characteristics that predict such involvement, attitudes toward relationships with PRs, correlations between the extent of involvement and attitudes, and differences in the extent of involvement according to self-reported prescribing behaviors. METHODS AND FINDINGS: From January to March 2008, we conducted a national survey of 2621 practicing physicians in seven specialties: internal medicine, general surgery, orthopedic surgery, pediatrics, obstetrics-gynecology, psychiatry, and ophthalmology. The response rate was 54%. Most physicians met with PRs (98%, received drug samples (85% and stationery (96%, and participated in industry-sponsored continuing medical education (CME events at the workplace (80% and outside the workplace (93%. Half accepted meals outside the workplace (49% and financial subsidies to attend CME events (49%. Rules at the workplace banning both meetings with PRs and gifts predicted less involvement of physicians in promotional activities. Physicians valued information from PRs. They believed that they were unlikely to be influenced by promotional activities, but that their colleagues were more susceptible to such influence than themselves. They were divided about the appropriateness of low-value gifts. The extent of physician involvement in promotional activities was positively correlated with the attitudes that PRs are a valuable source of information and that gifts are appropriate. The extent of such involvement was higher among physicians who prefer to ask PRs for information when a new medication becomes available, physicians who are not satisfied with patient encounters ending only with advice, and physicians who prefer to

2013-01-01

Background: Chronic kidney disease is an important risk factor for death and cardiovascular-related morbidity, but estimates to date of its prevalence in Canada have generally been extrapolated from the prevalence of end-stage renal disease. We used direct measures of kidney function collected from a nationally representative survey population to estimate the prevalence of chronic kidney disease among Canadian adults. Methods: We examined data for 3689 adult participants of cycle 1 of the Canadian Health Measures Survey (2007–2009) for the presence of chronic kidney disease. We also calculated the age-standardized prevalence of cardiovascular risk factors by chronic kidney disease group. We cross-tabulated the estimated glomerular filtration rate (eGFR) with albuminuria status. Results: The prevalence of chronic kidney disease during the period 2007–2009 was 12.5%, representing about 3 million Canadian adults. The estimated prevalence of stage 3–5 disease was 3.1% (0.73 million adults) and albuminuria 10.3% (2.4 million adults). The prevalence of diabetes, hypertension and hypertriglyceridemia were all significantly higher among adults with chronic kidney disease than among those without it. The prevalence of albuminuria was high, even among those whose eGFR was 90 mL/min per 1.73 m2 or greater (10.1%) and those without diabetes or hypertension (9.3%). Awareness of kidney dysfunction among adults with stage 3–5 chronic kidney disease was low (12.0%). Interpretation: The prevalence of kidney dysfunction was substantial in the survey population, including individuals without hypertension or diabetes, conditions most likely to prompt screening for kidney dysfunction. These findings highlight the potential for missed opportunities for early intervention and secondary prevention of chronic kidney disease. PMID:23649413

This article examines domestic violence among women who participate in microfinance in Bangladesh. Secondary analysis of survey data from nationally representative Bangladesh Demographic and Health Survey was used to investigate the association between microfinance participation and domestic violence of 4,163 ever-married women between the ages of 18 and 49 years. Outcome measure is experience of domestic violence as measured by a modified Conflict Tactics Scale (CTS) and predictor variables include microfinance, binary indicator of relatively better economic status, autonomy, decision-making power, and demographic variables. The likelihood of experiencing domestic violence was not found to vary with microfinance participation. However, the interaction effect of microfinance and better economic status was found to be significantly associated with domestic violence (9% increased probability). Experience of domestic violence was negatively associated with older age, higher education of the husband, and autonomy. In Bangladesh, microfinance participation may be associated with a higher probability of experiencing domestic violence for women with relatively better economic status, but not for the poorest of the poor. © The Author(s) 2015.

2007-07-01

Full Text Available Abstract Background The objective of the present study was to compare three different sampling and questionnaire administration methods used in the international KIDSCREEN study in terms of participation, response rates, and external validity. Methods Children and adolescents aged 8–18 years were surveyed in 13 European countries using either telephone sampling and mail administration, random sampling of school listings followed by classroom or mail administration, or multistage random sampling of communities and households with self-administration of the survey materials at home. Cooperation, completion, and response rates were compared across countries and survey methods. Data on non-respondents was collected in 8 countries. The population fraction (PF, respondents in each sex-age, or educational level category, divided by the population in the same category from Eurostat census data and population fraction ratio (PFR, ratio of PF and their corresponding 95% confidence intervals were used to analyze differences by country between the KIDSCREEN samples and a reference Eurostat population. Results Response rates by country ranged from 18.9% to 91.2%. Response rates were highest in the school-based surveys (69.0%–91.2%. Sample proportions by age and gender were similar to the reference Eurostat population in most countries, although boys and adolescents were slightly underrepresented (PFR Conclusion School-based sampling achieved the highest overall response rates but also produced slightly more biased samples than the other methods. The results suggest that the samples were sufficiently representative to provide reference population values for the KIDSCREEN instrument.

Timberlake, David S

2016-08-01

Brand of smokeless tobacco was added to the most recent Tobacco Use Supplement to the Current Population Survey (TUS-CPS), but deleted from the Centers for Disease Control's National Adult Tobacco Survey. The objective of this study was to assess the utility of brand in distinguishing users of moist snuff. The sample consisted of participants from the 2010-2011 TUS-CPS who reported having used one of 14 brands of moist snuff in the past month (n = 2334). The brands were categorized into one of three types: snus, discount snuff, premium snuff. Multinomial logistic regression was employed for testing for associations between brand type and a series of demographic and tobacco use measures. Females, metropolitan residents, current smokers, and moderate users of snuff had significantly greater odds of using snus relative to premium snuff in the adjusted model (P discount versus premium snuff. Separate analyses among current smokers (n = 470) and former smokers (n = 70) revealed positive associations between smoking cessation attempts and smokers' switch to discount snuff. Differences among the three categories of snuff users are likely attributed to variations in marketing campaigns. The differences are sufficient to warrant inclusion of snuff brand in health surveys because brand type could serve as a proxy measure for snuff use and dependence. Inclusion of brand of moist snuff in health surveys will enable researchers to categorize snuff users by brand type. Findings from this study indicate that brand type, defined according to cost (ie, discount vs. premium brands) and type of preferred snuff (ie, snus vs. other moist snuff), can distinguish snuff users by various demographic and tobacco use measures. Consequently, categorization by brand type could be used as a proxy measure for studies whose surveys do not include detailed information on snuff use and behavior. © The Author 2016.

In Equatorial Guinea, as a result of the recent growth of the oil industry, there is an opportunity to address important public health problems through public and private initiatives. To propose effective nutrition and public health strategies, it is important first to have reliable information on the nutritional status of the population and the underlying factors affecting it. To assess the nutritional status and the prevalence of anemia among Equatoguinean children in a nationally representative sample and to identify the risk factors associated with the nutritional problems detected. The study was a cross-sectional survey using a multistaged, stratified, cluster-selected sample. The survey included a sociodemographic, health, and dietary questionnaire and measurement of hematocrit and anthropometric features, from which nutritional indicators based on the National Center for Health Statistics (NCHS) reference and the World Health Organization (WHO) standards were calculated. Logistic regression models were used for the multivariate analysis. A total of 552 children aged 0 to 60 months were surveyed. The overall prevalence of stunting (hemoglobin hemoglobin education, should be undertaken.

The prevalence of workaholism: a survey study in a nationally representative sample of Norwegian employees.

Directory of Open Access Journals (Sweden)

Cecilie Schou Andreassen

Full Text Available Workaholism has become an increasingly popular area for empirical study. However, most studies examining the prevalence of workaholism have used non-representative samples and measures with poorly defined cut-off scores. To overcome these methodological limitations, a nationally representative survey among employees in Norway (N = 1,124 was conducted. Questions relating to gender, age, marital status, caretaker responsibility for children, percentage of full-time equivalent, and educational level were asked. Workaholism was assessed by the use of a psychometrically validated instrument (i.e., Bergen Work Addiction Scale. Personality was assessed using the Mini-International Personality Item Pool. Results showed that the prevalence of workaholism was 8.3% (95% CI  = 6.7-9.9%. An adjusted logistic regression analysis showed that workaholism was negatively related to age and positively related to the personality dimensions agreeableness, neuroticism, and intellect/imagination. Implications for these findings are discussed.

Who Justifies Questionable Reporting Practices? Answers from a Representative Survey of Journalists in Germany

Directory of Open Access Journals (Sweden)

Philip Baugut

2017-07-01

Full Text Available Based on a secondary analysis of representative survey data of journalists in Germany (n= 1536, this paper draws attention to two variables that are important when it comes to explain whether journalists accept questionable reporting practices, such as paying people to obtain information or using confidential government documents without permission. First, perceived role achievement is important, as journalists who do not feel able to achieve an active role tend to accept questionable reporting practices more often. Second, however, this relationship is only true for journalists having a moderate tendency to the political left. Findings are explained by means of the theory of cognitive dissonance.

Vegetarian diet and mental disorders: results from a representative community survey

Science.gov (United States)

2012-01-01

Background The present study investigated associations between vegetarian diet and mental disorders. Methods Participants were drawn from the representative sample of the German Health Interview and Examination Survey and its Mental Health Supplement (GHS-MHS). Completely vegetarian (N = 54) and predominantly vegetarian (N = 190) participants were compared with non-vegetarian participants (N = 3872) and with a non-vegetarian socio-demographically matched subsample (N = 242). Results Vegetarians displayed elevated prevalence rates for depressive disorders, anxiety disorders and somatoform disorders. Due to the matching procedure, the findings cannot be explained by socio-demographic characteristics of vegetarians (e.g. higher rates of females, predominant residency in urban areas, high proportion of singles). The analysis of the respective ages at adoption of a vegetarian diet and onset of a mental disorder showed that the adoption of the vegetarian diet tends to follow the onset of mental disorders. Conclusions In Western cultures vegetarian diet is associated with an elevated risk of mental disorders. However, there was no evidence for a causal role of vegetarian diet in the etiology of mental disorders. PMID:22676203

Two novel Pb(II) coordination polymers (CPs) based on 4-(4-oxopyridin-1(4H)-yl) and 3-(4-oxopyridin-1(4H)-yl) phthalic acid: Band gaps, structures, and their photoelectrocatalytic properties in CO2-saturated system

Based on 4-(4-oxopyridin-1(4H)-yl) phthalic acid (H2L1) and 3-(4-oxopyridin-1(4H)-yl) phthalic acid (H2L2), two novel Pb(II) coordination polymers (CPs) formulated as [Pb4Cl4·(L1)2·H2O]n (CP 1), [Pb3Cl4·L2·H2O]n (CP 2) were solvothermally synthesized and characterized by single-crystal X-ray diffraction. The two novel Pb(II) CPs (CPs 1 and 2) possessed different structures. Density functional theory (DFT) calculations revealed the two CPs had different band structures yet the characteristic of semiconductors in common. Their valence band (VB) and conduction band (CB) positions were determined by Mott-Schottky and UV-visible diffuse reflectance analyses. The photoelectrocatalytic performance of the two CPs towards CO2 reduction were tested by photocurrent responses at various applied potentials. And the E =-1.4 V vs SCE (-0.74 V vs NHE) was selected as the required potential according to the regulation of photocurrent responses at various tested potentials in CO2-saturated system. The photoelectrocatalytic performance of CP 2 was superior to that of CP 1 owing to the well-matched CB position of CP 2 and CO2 reduction potentials at the required potential of -1.4 V vs SCE (-0.74 V vs NHE). In addition, the photoelectrolytic experiment were performed 1 h in the CO2-saturated 0.2 M Na2SO4 solution at the required potential of -1.4 V vs SCE (-0.74 V vs NHE) with and without illumination, and we initially demonstrated the influence of visible light in the CO2-saturated photoelectrocatalytic measurement system and the reason of stability in 1 h chronoamperometry.

Bedard, Jeffrey; Moore, Crystal Dea; Shelton, Wayne

2014-01-01

To provide preliminary evidence of the types and amount of involvement by healthcare industry representatives (HCIRs) in surgery, as well as the ethical concerns of those representatives. A link to an anonymous, web-based survey was posted on several medical device boards of the website http://www. cafepharma.com. Additionally, members of two different medical device groups on LinkedIn were asked to participate. Respondents were self-identified HCIRs in the fields of orthopedics, cardiology, endoscopic devices, lasers, general surgery, ophthalmic surgery, oral surgery, anesthesia products, and urologic surgery. A total of 43 HCIRs replied to the survey over a period of one year: 35 men and eight women. Respondents reported attending an average of 184 surgeries in the prior year and had an average of 17 years as an HCIR and six years with their current employer. Of the respondents, 21 percent (nine of 43) had direct physical contact with a surgical team or patient during a surgery, and 88 percent (38 of 43) provided verbal instruction to a surgical team during a surgery. Additionally, 37 percent (16 of 43) had participated in a surgery in which they felt that their involvement was excessive, and 40 percent (17 of 43) had attended a surgery in which they questioned the competence of the surgeon. HCIRs play a significant role in surgery. Involvement that exceeds their defined role, however, can raise serious ethical and legal questions for surgeons and surgical teams. Surgical teams may at times be substituting the knowledge of the HCIR for their own competence with a medical device or instrument. In some cases, contact with the surgical team or patient may violate the guidelines not only of hospitals and medical device companies, but the law as well. Further study is required to determine if the patients involved have any knowledge or understanding of the role that an HCIR played in their surgery. Copyright 2014 The Journal of Clinical Ethics.

There is little systematic information about health risk behaviours among youth in Middle Eastern countries, leaving public health authorities unprepared to deal with emerging public health threats at a time of major social change. The Palestinian Youth Health Risk study investigates patterns of risk behaviours among Palestinian youth, their perceptions of the risks and benefits of such behaviours, and the relationship of exposure to violence with mental health and engagement in risk behaviours. We conducted a representative survey among 2500 individuals aged 15-24 years in the West Bank and East Jerusalem, permitting reliable comparison across sex and rural-urban divisions. A stratified 2-stage random sample was drawn from the 2007 population census, with strata formed by crossing the 12 governorates with urban, rural and refugee camp locations. Within strata, 208 survey clusters were sampled with probability proportional to size. Within each cluster, 14 households with youth of the appropriate age were sampled. Among youth aged 20-24 years, 22.4% of males and 11.6% of females reported trying alcohol; 10.5% of males and 4.3% of females reported trying drugs. Almost one quarter of unmarried youth aged 20-24 years reported any sexual experience. Tobacco use is high, even among younger youth (45.4% of males and 21.2% of females aged 15-19 smoke). Risk behaviours are higher among males, older youth and in urban areas and refugee camps. While smoking is of particular concern, prevention outreach for all behaviours should be directed at subgroups and areas identified as highest risk. Copyright © World Health Organization (WHO) 2018.

Agius, Matthew; Van Noten, Koen; Ermert, Laura; Mai, P. Martin; Krawczyk, CharLotte

2016-04-01

The European Geosciences Union is a bottom-up-organisation, in which its members are represented by their respective scientific divisions, committees and council. In recent years, EGU has embarked on a mission to reach out for its numerous 'younger' members by giving awards to outstanding young scientists and the setting up of Early Career Scientists (ECS) representatives. The division representative's role is to engage in discussions that concern students and early career scientists. Several meetings between all the division representatives are held throughout the year to discuss ideas and Union-wide issues. One important impact ECS representatives have had on EGU is the increased number of short courses and workshops run by ECS during the annual General Assembly. Another important contribution of ECS representatives was redefining 'Young Scientist' to 'Early Career Scientist', which avoids discrimination due to age. Since 2014, the Seismology Division has its own ECS representative. In an effort to more effectively reach out for young seismologists, a blog and a social media page dedicated to seismology have been set up online. With this dedicated blog, we'd like to give more depth to the average browsing experience by enabling young researchers to explore various seismology topics in one place while making the field more exciting and accessible to the broader community. These pages are used to promote the latest research especially of young seismologists and to share interesting seismo-news. Over the months the pages proved to be popular, with hundreds of views every week and an increased number of followers. An online survey was conducted to learn more about the activities and needs of early career seismologists. We present the results from this survey, and the work that has been carried out over the last two years, including detail of what has been achieved so far, and what we would like the ECS representation for Seismology to achieve. Young seismologists are

Medical cyber-physical systems (MCPS) are healthcare critical integration of a network of medical devices. These systems are progressively used in hospitals to achieve a continuous high-quality healthcare. The MCPS design faces numerous challenges, including inoperability, security/privacy, and high assurance in the system software. In the current work, the infrastructure of the cyber-physical systems (CPS) are reviewed and discussed. This article enriched the researches of the networked Medical Device (MD) systems to increase the efficiency and safety of the healthcare. It also can assist the specialists of medical device to overcome crucial issues related to medical devices, and the challenges facing the design of the medical device's network. The concept of the social networking and its security along with the concept of the wireless sensor networks (WSNs) are addressed. Afterward, the CPS systems and platforms have been established, where more focus was directed toward CPS-based healthcare. The big data framework of CPSs is also included.

Full Text Available Objectives: To examine the frequency of pharmaceutical company representative (PCR interactions with doctors in Libya and review possible associations between these interactions and the personal and practice setting characteristics of doctors. Method: An anonymous survey questionnaire was circulated to 1,000 Libyan doctors in selected public and private practice settings in Tripoli, Benghazi and Sebha. Results: A questionnaire return rate of 61% (608 returned questionnaires was achieved. Most respondents (94% reported that they had been visited by PCRs at least ‘once’ in the last year. Fifty per cent of respondents met with PCRs at least once a month, and 20% at least once a week. The following characteristics were significantly associated with meeting with a representative more than once a week: age, gender (male > female, years of practice, being a specialist (other than an anaesthesiologist or working in private practice. Ninety-one per cent of doctors reported that they had received at least one kind of relationship gift during the last year. Printed materials (79%, simple gifts (73% and drug samples (69% were the most common relationship products given to respondents. Reimbursements or sponsored items were reported by 33% of respondents. Physician specialists were more likely to receive drug samples or sponsored items than residents, general practitioners, anaesthesiologists or surgeons (P<0.01. Participants working in private practice alone or in both sectors were more likely to receive printed materials, simple gifts or free samples from PCRs than doctors working in the public sector (P<0.05. Conclusion: Libyan doctors are frequently visited by PCRs. Doctors, working in private practice or specialist practice, are especially targeted by promotional activities. An agreed code of conduct for pharmaceutical promotion in Libya between doctors and PCRs should be created.

Background To clarify the relationship between the general attitude towards gestational surrogacy and risk perception about pregnancy and infertility treatment. Materials and Methods This study analysed the data of nationally representative cross-sectional surveys from 2007 concerning assisted reproductive technologies. The participants represented the general Japanese population. We used this data to carry out multivariate analysis. The main outcome measures were adjusted odds ratios and 95% confidence intervals from logistic regression models for factors including the effect of pregnancy risk perception on the attitude toward gestational surrogacy. Results In this survey, 3412 participants responded (response rate of 68.2%). With regard to the attitude towards gestational surrogacy, 54.0% of the respondents approved of it, and 29.7% stated that they were undecided. The perception of a high level of risk concerning ectopic pregnancy, threatened miscarriage or premature birth, and pregnancy-induced hypertension influenced the participants’ attitudes towards gestational surrogacy. Moreover, this perception of risk also contributed to a disapproval of the technique. Conclusion Our findings suggest that a person who understands the risks associated with pregnancy might clearly express their disapproval of gestational surrogacy. PMID:24963363

Design and evaluation of representative indoor radon surveys

International Nuclear Information System (INIS)

Csige, I.; Csegzi, S.

2004-01-01

We have developed a procedure to design and evaluate representative indoor radon surveys. The procedure is based on random sampling of a population of houses and careful statistical analysis of measured indoor radon concentrations. The method is designed to estimate the fraction of houses in which annual average 222 Rn activity concentration may exceed a certain reference level. Measurements of annual average indoor 222 Rn activity concentration were done in sleeping rooms at pillow level using etched track type radon detectors. We applied the above procedure in an old fashioned village and in a fast developing small city in Transylvania, Romania. In the village almost all houses were single floor wooden made houses without cellar built with traditional technology on a geologically uniform area. The distribution of indoor 222 Rn activity concentration in a sample of 115 houses can almost perfectly be fitted with log-normal probability density function. The correlation coefficient of linear fitting on linearized scales was k = -0.9980. The percentages of houses expected to have annual average 222 Rn activity concentration higher than 400 Bq m -3 is less than 1 %, and of those higher than 600 Bq m -3 can be estimated to be around 0.1 %. The small city, on the other hand lies on a geologically inhomogeneous area, and house construction technology has also changed dramatically in past decades. The resulting distribution of measured indoor 222 Rn activity concentration in a sample of 116 houses cannot be fitted with any simple probability density function. Therefore the prediction of the fraction of houses in which the annual average 222 Rn activity concentration may exceed a certain reference level could not be done adequately. With certain assumptions we estimated that the percentages of houses expected to have annual average 222 Rn activity concentration higher than 400 Bq m -3 is between 3 and 7 %, and of those higher than 600 Bq m -3 can be estimated to be between

Self-reported use of novel psychoactive substances in a US nationally representative survey: Prevalence, correlates, and a call for new survey methods to prevent underreporting.

2015-11-01

In recent years, there has been an increase in emergence and use of novel psychoactive substances (NPS) in the US and worldwide. However, there is little published epidemiological survey data estimating the prevalence of use in the US. Data on self-reported NPS use came from the National Survey of Drug Use and Health (2009-2013), a national representative sample of non-institutionalized individuals in the US. Subjects were asked to provide names of (non-traditional) drugs they used that they were not specifically asked about. We examined lifetime prevalence and sociodemographic correlates of self-reported use of new and uncommon synthetic drugs (NPS) among subjects ages 12-34-years-old. 1.2% of subjects self-reported any use of the 57 NPS we examined. Use of psychedelic tryptamines (primarily DMT) was most common, followed by psychedelic phenethylamines (e.g., 2C series) and synthetic cannabinoids. Prevalence of self-reported use of NPS increased from 2009 to 2013 and use was most common among males, whites, older subjects, those of lower income, and among those residing in cities. Lifetime use of various other illicit drugs (e.g., LSD, cocaine, ecstasy/MDMA) was highly prevalent among NPS users. This the first study reporting on use of a variety of NPS in a nationally representative US sample; however, use appears to be underreported as other national data suggest higher rates of NPS (e.g., synthetic cannabinoid) use. Developing more adaptable survey tools and systematically assessing NPS use would allow researchers to ask about hundreds of NPS and improve reporting as new drugs continue to rapidly emerge.

2008-03-01

Full Text Available Counselling or prescribing drugs during pregnancy requires health professionals to assess risk/benefit ratio for women and their baby. A misperception of the risk may lead to inappropriate decisions for pregnancy outcomes. The aim of the present study was to assess teratogenic and/or foetotoxic risk perception of common medications by general practitioners (GPs and community pharmacists (CPs from the Midi-Pyrenees area.Methods: 103 GPs and 104 CPs were interviewed. For 21 given drugs, a visual-analogue scale was used to evaluate the risk to give birth to a malformed infant if the mother had taken the drug during first trimester of pregnancy. For 9 drugs, health professionals had to say if they thought there was a potential foetotoxic and/or neonatal risk when drugs were administered during late pregnancy.Results: 97% and 91% of GPs and CPs respectively thought that isotretinoin and thalidomide are teratogenic and more than 80% thought that amoxicillin and acetaminophen are safe in early pregnancy. However, 19% of the GPs and 33% of CPs answered there were no teratogenic risk for valproate. Around 11% of both GPs and CPs said that warfarin was safe during pregnancy. For 22% of GPs and for 13% and 27% of CPs respectively, ibuprofen and enalapril were safe on late pregnancy. For each drug, mean value of perceived teratogenic risk by health professionals was higher than values that can be found in scientific references. Concerning isotretinoin, thalidomide and metoclopramide, perceived teratogenic risk was higher for CPs.Conclusion: These data show that the potential teratogenic and foetotoxic risk of several commonly used drugs is unknown by health professionals. Conversely, GPs and CPs who think that a risk exists, overestimate it. This misperception can lead to inappropriate decisions for pregnancy outcomes.

2017-06-01

Micronutrient deficiencies are still highly prevalent in countries undergoing the nutrition transition, but nationally representative data documenting their burden in children are exceedingly rare. To examine the distribution and recent trends in micronutrient status biomarkers of Colombian children. We compared the distributions of plasma ferritin, serum zinc, and vitamin A in Colombian children between 2005 and 2010 using 2 cross-sectional, nationally representative surveys overall and by categories of sociodemographic variables. Analysis for ferritin included boys and nonpregnant girls aged 1 to 17 years. Analyses for zinc and vitamin A included children aged 1 to 4 years. The mean 2010 to 2005 differences in ferritin, zinc, and vitamin A were 2.5 µg/L (95% confidence interval [CI]: 1.3 to 3.7), -34.9 µg/dL (95% CI: -39.6 to -30.2), and -11.5 µg/dL (95% CI: -12.3 to -10.7), respectively, after adjusting for sociodemographic characteristics. These differences varied significantly by region of residence. In 2010, region of residence was a significant correlate for all 3 micronutrients. Other important correlates included age and maternal education for ferritin and body mass index-for-age Z score, maternal education, wealth index, food insecurity, and urbanicity for vitamin A. Plasma ferritin was slightly higher in 2010 than in 2005, whereas serum zinc and vitamin A were substantially lower in 2010. In the absence of obvious causal explanations, it is uncertain whether this decline represents a worsening of micronutrient status in Colombian children or an artifact due to systematic laboratory or data management errors incurred in the surveys.

This study assessed whether postal follow-up to a web-based physician survey improves response rates, response quality, and representativeness. We recruited primary care and gastroenterology chiefs at 125 Veterans Affairs medical facilities to complete a 10-min web-based survey on colorectal cancer screening and diagnostic practices in 2010. We compared response rates, response errors, and representativeness in the primary care and gastroenterology samples before and after adding postal follow-up. Adding postal follow-up increased response rates by 20-25 percentage points; markedly greater increases than predicted from a third e-mail reminder. In the gastroenterology sample, the mean number of response errors made by web responders (0.25) was significantly smaller than the mean number made by postal responders (2.18), and web responders provided significantly longer responses to open-ended questions. There were no significant differences in these outcomes in the primary care sample. Adequate representativeness was achieved before postal follow-up in both samples, as indicated by the lack of significant differences between web responders and the recruitment population on facility characteristics. We conclude adding postal follow-up to this web-based physician leader survey improved response rates but not response quality or representativeness. © The Author(s) 2013.

Design and characterization of calcium phosphate ceramic scaffolds for bone tissue engineering.

Science.gov (United States)

Denry, Isabelle; Kuhn, Liisa T

2016-01-01

Our goal is to review design strategies for the fabrication of calcium phosphate ceramic scaffolds (CPS), in light of their transient role in bone tissue engineering and associated requirements for effective bone regeneration. We examine the various design options available to meet mechanical and biological requirements of CPS and later focus on the importance of proper characterization of CPS in terms of architecture, mechanical properties and time-sensitive properties such as biodegradability. Finally, relationships between in vitro versus in vivo testing are addressed, with an attempt to highlight reliable performance predictors. A combinatory design strategy should be used with CPS, taking into consideration 3D architecture, adequate surface chemistry and topography, all of which are needed to promote bone formation. CPS represent the media of choice for delivery of osteogenic factors and anti-infectives. Non-osteoblast mediated mineral deposition can confound in vitro osteogenesis testing of CPS and therefore the expression of a variety of proteins or genes including collagen type I, bone sialoprotein and osteocalcin should be confirmed in addition to increased mineral content. CPS are a superior scaffold material for bone regeneration because they actively promote osteogenesis. Biodegradability of CPS via calcium and phosphate release represents a unique asset. Structural control of CPS at the macro, micro and nanoscale and their combination with cells and polymeric materials is likely to lead to significant developments in bone tissue engineering.

2012-03-01

Roughly half the labor force data in the Current Population Survey (CPS) are provided by proxy respondents, and since 1979, men's reliance on proxies has dropped dramatically while women's reliance on proxies has increased. Few authors, however, have examined how combining these first-hand and second-hand reports may influence our understanding of long-term economic trends. We exploit the outgoing rotation group structure of the CPS by matching individual records one year apart, and we find that self-reported wages are higher than proxy-reported wages even after controlling for all time invariant characteristics. Furthermore, we find that changes in the use of proxy respondents by men and women since 1979 have made current estimates of the gender wage gap larger than they would have been without changes in reporting status. This suggests that the gender wage gap has closed more than previously estimated. We recommend that researchers combine self and proxy responses with great care, especially when analyzing time trends or making gender comparisons. Copyright © 2011 Elsevier Inc.

Connectedness to nature (CN) influences motivation to have contact with outdoor natural environments. Spending leisure time in natural environments is beneficial for human health and well-being. Besides these positive effects, health risks of open-air activities are mainly related to unprotected sun light exposure-associated acute and chronic skin hazards. Thus, we conducted a cross-sectional, representative telephone survey among Austrian residents to study the association of perceived CN level with sun-exposure knowledge, tanning habits, and sun protective behaviour. In total, 1,500 study subjects (50.5% females) participated in this questionnaire survey. Although knowledge about tanning and motives to tan were similar among genders, females performed more photoprotective measures and were more connected to nature (all p nature connectedness and skin health-relevant recreational habits of Austrian residents. The findings suggest to integrate hitherto neglected gender-specific Public (Skin) Health promotion when counselling on the manifold health advantages of outdoor activities.

Major depressive disorder (MDD) is the most prevalent mental disorder in the general population and has been associated with socioeconomic factors. Beijing has undergone significant socioeconomic changes in last decade, however no large-scale community epidemiological surveys of MDD have been conducted in Beijing since 2003. To determine the prevalence of MDD and its socio-demographic correlates in a representative household sample of the general population in Beijing, China. Data were collected from the 2010 representative household epidemiological survey of mental disorders in Beijing. The multistage cluster random sampling method was used to select qualified subjects in 18 districts and counties, and then face-to-face interviews were administered using the Chinese version of Structured Clinical Interview for DSM-IV-TR Axis I Disorders-Patient Edition (SCID-I/P) during November 1, 2010 to December 31, 2010. 19,874 registered permanent residents were randomly identified and 16,032 (response rate=80.7%) completed face-to-face interviews. The time-point and life-time prevalence rates of MDD were estimated to be 1.10% (95% CI: 0.94-1.26%) and 3.56% (95% CI: 3.27-3.85%) respectively. Significant differences were found in sex, age, location of residence, marital status, education, employment status, personal/family monthly income, perception of family environment and relationship with others, when comparing residents with MDD to those without MDD. Those who were female, aged 45 or above, reported low family income, or reported an "average" or "poor" family environment were associated with a higher risk of MDD. The prevalence of MDD reported in this survey is relatively lower than that in other western countries. Female sex, age older than 45, low family income, and poor family environment appear to be independent risk factors for MDD. Copyright © 2015 Elsevier B.V. All rights reserved.

Inconsistent censoring in the public-use March Current Population Survey (CPS) limits its usefulness in measuring labor earnings trends. Using Pareto estimation methods with less-censored internal CPS data, we create an enhanced cell-mean series to capture top earnings in the public-use CPS. We find that previous approaches for imputing topcoded earnings systematically understate top earnings. Annual earnings inequality trends since 1963 using our series closely approximate those found by Kop...

Quality of Artemisinin-Containing Antimalarials in Tanzania's Private Sector--Results from a Nationally Representative Outlet Survey.

Science.gov (United States)

Act Consortium Drug Quality Project Team And The Impact Study Team

2015-06-01

Ensuring that artemisinin-containing antimalarials (ACAs) are of good quality is a key component of effective malaria treatment. There are concerns that a high proportion of ACAs are falsified or substandard, though estimates are rarely based on representative data. During a nationally representative survey in Tanzania, ACAs were purchased from private retail drug outlets, and the active pharmaceutical ingredient (API) was measured. All 1,737 ACAs contained the labeled artemisinin derivative, with 4.1% being outside the 85-115% artemisinin API range defined as acceptable quality. World Health Organization (WHO) prequalified drugs had 0.1 times the odds of being poor quality compared with non-prequalified ACAs for the artemisinin component. When partner components of combination therapies were also considered, 12.1% were outside the acceptable API range, and WHO prequalified ACAs had 0.04 times the odds of being poor quality. Although the prevalence of poor quality ACAs was lower than reported elsewhere, the minority of samples found to be substandard is a cause for concern. Improvements in quality could be achieved by increasing the predominance of WHO prequalified products in the market. Continued monitoring of quality standards is essential. © The American Society of Tropical Medicine and Hygiene.

The aim of this study was to survey GPs and community pharmacists (CPs) in Ireland regarding current practices of medication management, specifically medication reconciliation, communication between health care providers and medication errors as patients transition in care. A national cross-sectional survey was distributed electronically to 2364 GPs, 311 GP Registrars and 2382 CPs. Multivariable associations comparing GPs to CPs were generated and content analysis of free text responses was undertaken. There was an overall response rate of 17.7% (897 respondents-554 GPs/Registrars and 343 CPs). More than 90% of GPs and CPs were positive about the effects of medication reconciliation on medication safety and adherence. Sixty per cent of GPs reported having no formal system of medication reconciliation. Communication between GPs and CPs was identified as good/very good by >90% of GPs and CPs. The majority (>80%) of both groups could clearly recall prescribing errors, following a transition of care, they had witnessed in the previous 6 months. Free text content analysis corroborated the positive relationship between GPs and CPs, a frustration with secondary care communication, with many examples given of prescribing errors. While there is enthusiasm for the benefits of medication reconciliation there are limited formal structures in primary care to support it. Challenges in relation to systems that support inter-professional communication and reduce medication errors are features of the primary/secondary care transition. There is a need for an improved medication management system. Future research should focus on the identified barriers in implementing medication reconciliation and systems that can improve it. © The Author 2016. Published by Oxford University Press.

A survey of licensee staff members representing the several organizational elements in different licensee corporate and plant staffs was conducted by senior NRC management to obtain licensee views on the potential safety consequences and impact of NRC regulatory activities. The comments received addressed the full scope of NRC activities and the negative impact of agency actions on licensee resources, staff performance, planning and scheduling, and organizational effectiveness. The findings of the survey is that the pace and nature of regulatory actions have created a potential safety problem which deserves further evaluation by the agency

Until now older adults have not been a target group for surveys regarding their personal attitudes towards euthanasia, although they are closest to chronic illness and death. To determine the attitudes of older adults towards euthanasia and controversial topics in the context of illness, euthanasia and care (e. g. palliative care) on the basis of a representative sample. The study was based on a postal survey of a representative random sample of the population aged 65 years and older (n = 3500) from a city in southern Germany using a standardized questionnaire. A total of 1068 persons completed the questionnaire (response rate 30.5%). Assisted death was supported by 74.2% of the respondants and assisted suicide by 80.4%. According to multiple logistic regression analysis the support decreased with increasing strength of religious faith and a non-German country of origin. Of the participants 53.3% were worried about being a burden to their family, especially people with a limited state of health. People who shared this concern showed significantly more support for both types of euthanasia. More than 40% feared that people with severe and incurable illnesses would be more likely to be forced into a premature death (slippery slope argument). This concern was associated with a decreasing support of euthanasia. The results indicate that the strong approval of the legalization of assisted death and assisted suicide by older people is motivated not only by their desire for a self-determined death but also by fears and concerns. The findings have important implications for counseling, palliative care and treatment.

Capsular Sialyltransferase Specificity Mediates Different Phenotypes in Streptococcus suis and Group B Streptococcus

Directory of Open Access Journals (Sweden)

David Roy

2018-04-01

Full Text Available The capsular polysaccharide (CPS represents a key virulence factor for most encapsulated streptococci. Streptococcus suis and Group B Streptococcus (GBS are both well-encapsulated pathogens of clinical importance in veterinary and/or human medicine and responsible for invasive systemic diseases. S. suis and GBS are the only Gram-positive bacteria which express a sialylated CPS at their surface. An important difference between these two sialylated CPSs is the linkage between the side-chain terminal galactose and sialic acid, being α-2,6 for S. suis but α-2,3 for GBS. It is still unclear how sialic acid may affect CPS production and, consequently, the pathogenesis of the disease caused by these two bacterial pathogens. Here, we investigated the role of sialic acid and the putative effect of sialic acid linkage modification in CPS synthesis using inter-species allelic exchange mutagenesis. To this aim, a new molecular biogenetic approach to express CPS with modified sialic acid linkage was developed. We showed that sialic acid (and its α-2,6 linkage is crucial for S. suis CPS synthesis, whereas for GBS, CPS synthesis may occur in presence of an α-2,6 sialyltransferase or in absence of sialic acid moiety. To evaluate the effect of the CPS composition/structure on sialyltransferase activity, two distinct capsular serotypes within each bacterial species were compared (S. suis serotypes 2 and 14 and GBS serotypes III and V. It was demonstrated that the observed differences in sialyltransferase activity and specificity between S. suis and GBS were serotype unrestricted. This is the first time that a study investigates the interspecies exchange of capsular sialyltransferase genes in Gram-positive bacteria. The obtained mutants represent novel tools that could be used to further investigate the immunomodulatory properties of sialylated CPSs. Finally, in spite of common CPS structural characteristics and similarities in the cps loci, sialic acid exerts

El Ansari, Walid; Oskrochi, Reza; Phillips, Ceri

2009-01-01

A multi-site evaluation (survey) of five Kellogg-funded Community Partnerships (CPs) in South Africa was undertaken to explore the relationship between leadership skills and a range of 30 operational, functional and organisational factors deemed critical to successful CPs. The CPs were collaborative academic-health service-community efforts aimed at health professions education reforms. The level of agreement to eleven dichotomous ('Yes/No') leadership skills items was used to compute two measures of members' appreciation of their CPs' leadership. The associations between these measures and 30 CPs factors were explored, and the partnership factors that leadership skills explained were assessed after controlling. Respondents who perceived the leadership of their CPs favourably had more positive ratings across 30 other partnership factors than those who rated leadership skills less favourably, and were more likely to report a positive cost/ benefit ratio. In addition, respondents who viewed their CPs' leadership positively also rated the operational understanding, the communication mechanisms, as well as the rules and procedures of the CPs more favourably. Leadership skills explained between 20% and 7% of the variance of 10 partnership factors. The influence of leaders' skills in effective health-focussed partnerships is much broader than previously conceptualised.

What people believe about how memory works: a representative survey of the U.S. population.

Directory of Open Access Journals (Sweden)

Daniel J Simons

Full Text Available Incorrect beliefs about the properties of memory have broad implications: the media conflate normal forgetting and inadvertent memory distortion with intentional deceit, juries issue verdicts based on flawed intuitions about the accuracy and confidence of testimony, and students misunderstand the role of memory in learning. We conducted a large representative telephone survey of the U.S. population to assess common beliefs about the properties of memory. Substantial numbers of respondents agreed with propositions that conflict with expert consensus: Amnesia results in the inability to remember one's own identity (83% of respondents agreed, unexpected objects generally grab attention (78%, memory works like a video camera (63%, memory can be enhanced through hypnosis (55%, memory is permanent (48%, and the testimony of a single confident eyewitness should be enough to convict a criminal defendant (37%. This discrepancy between popular belief and scientific consensus has implications from the classroom to the courtroom.

This paper presents a study of the environments of SDSS quasi-stellar objects (QSOs) in the Spitzer Extragalactic Representative Volume Survey (SERVS). We concentrate on the high-redshift QSOs as these have not been studied in large numbers with data of this depth before. We use the IRAC 3.6-4.5 μm color of objects and ancillary r-band data to filter out as much foreground contamination as possible. This technique allows us to find a significant (>4σ) overdensity of galaxies around QSOs in a redshift bin centered on z ∼ 2.0 and an (>2σ) overdensity of galaxies around QSOs in a redshift bin centered on z ∼ 3.3. We compare our findings to the predictions of a semi-analytic galaxy formation model, based on the ΛCDM MILLENNIUM simulation, and find for both redshift bins that the model predictions match well the source density we have measured from the SERVS data.

Full Text Available Background: To clarify the relationship between the general attitude towards gestational surrogacyand risk perception about pregnancy and infertility treatment.Materials and Methods: This study analysed the data of nationally representative cross-sectionalsurveys from 2007 concerning assisted reproductive technologies. The participants represented thegeneral Japanese population. We used this data to carry out multivariate analysis. The main outcomemeasures were adjusted odds ratios and 95% confidence intervals from logistic regression modelsfor factors including the effect of pregnancy risk perception on the attitude toward gestationalsurrogacy.Results: In this survey, 3412 participants responded (response rate of 68.2%. With regard to theattitude towards gestational surrogacy, 54.0% of the respondents approved of it, and 29.7% statedthat they were undecided. The perception of a high level of risk concerning ectopic pregnancy,threatened miscarriage or premature birth, and pregnancy-induced hypertension influencedthe participants’ attitudes towards gestational surrogacy. Moreover, this perception of risk alsocontributed to a disapproval of the technique.Conclusion: Our findings suggest that a person who understands the risks associated with pregnancymight clearly express their disapproval of gestational surrogacy.

Empowerment and Intimate Partner Violence in Pakistan: Results From a Nationally Representative Survey.

2017-02-01

Using empowerment theory, the current study examines antecedents of lifetime experience of intimate partner violence, intimate partner violence experienced in the last 12 months, emotional violence, and husbands' controlling behaviors toward their wives in Pakistan. Using data from a subsample of 658 women from the nationally representative Pakistan Demographic and Health Survey 2012-2013, this study examined whether empowerment variables, such as household decision-making power, economic decision-making power, and adherence to patriarchy, operationalized as justification of wife beating, contribute to intimate partner violence using logistic regression analyses. Results indicate that adherence to patriarchal norms, household decision-making power, and higher education was found to be associated with lifetime prevalence of intimate partner violence. Adherence to patriarchal norms, economic decision-making power, and higher education was found significantly associated with intimate partner violence in the past 12 months. Adherence to patriarchal norms was significantly associated with experiencing emotional violence as well as controlling behaviors by husbands. In conclusion, women's adherence to patriarchal norms is a reflection of the patriarchal society in which they live; indeed, this was found to be the most important predictor of women's experience of intimate partner violence, when different types of violence were assessed. Implications for social work practice are discussed.

Full Text Available Appropriate infant and young child feeding could reduce morbidity and mortality and could improve cognitive development of children. However, nationwide data on exclusive breastfeeding and complementary feeding status in China are scarce. The aim of this study was to assess current exclusive breastfeeding and complementary feeding status in China. A national representative survey (Chinese National Nutrition and Health Survey of children aged under 6 years was done in 2013. Stratified multistage cluster sampling was used to select study participants. World Health Organization (WHO infant and young child feeding indicators were firstly used to assess exclusive breastfeeding and complementary feeding practice nationwide. In total, 14,458 children aged under two years (0 to <730 days were studied from 55 counties in 30 provinces in China. The crude exclusive breastfeeding rate under 6 months was 20.7% (908/4381 and the weighted exclusive breastfeeding rate was 18.6%. The crude prevalence of minimum dietary diversity, minimum meal frequency and minimum acceptable diet were 52.5% (5286/10,071, 69.8% (7027/10,071, and 27.4% (2764/10,071 among children aged 6–23 months, respectively. The weighted rate was 53.7%, 69.1%, and 25.1%, respectively. Residential area, household income and maternal education were positively associated with the three complementary feeding indicators. The exclusive breastfeeding rate under 6 months was low and complementary feeding practice was not optimal in China. Residential area, household income and maternal education might be used to target infants and young children to improve complementary feeding practice.

Despite the high global burden of diseases caused by tobacco, valid and comparable prevalence data for patterns of adult tobacco use and factors influencing use are absent for many low-income and middle-income countries. We assess these patterns through analysis of data from the Global Adult Tobacco Survey (GATS). Between Oct 1, 2008, and March 15, 2010, GATS used nationally representative household surveys with comparable methods to obtain relevant information from individuals aged 15 years or older in 14 low-income and middle-income countries (Bangladesh, Brazil, China, Egypt, India, Mexico, Philippines, Poland, Russia, Thailand, Turkey, Ukraine, Uruguay, and Vietnam). We compared weighted point estimates and 95% CIs of tobacco use between these 14 countries and with data from the 2008 UK General Lifestyle Survey and the 2006-07 US Tobacco Use Supplement to the Current Population Survey. All these surveys had cross-sectional study designs. In countries participating in GATS, 48·6% (95% CI 47·6-49·6) of men and 11·3% (10·7-12·0) of women were tobacco users. 40·7% of men (ranging from 21·6% in Brazil to 60·2% in Russia) and 5·0% of women (0·5% in Egypt to 24·4% in Poland) in GATS countries smoked a tobacco product. Manufactured cigarettes were favoured by most smokers (82%) overall, but smokeless tobacco and bidis were commonly used in India and Bangladesh. For individuals who had ever smoked daily, women aged 55-64 years at the time of the survey began smoking at an older age than did equivalently aged men in most GATS countries. However, those individuals who had ever smoked daily and were aged 25-34-years when surveyed started to do so at much the same age in both sexes. Quit ratios were very low (<20% overall) in China, India, Russia, Egypt, and Bangladesh. The first wave of GATS showed high rates of smoking in men, early initiation of smoking in women, and low quit ratios, reinforcing the view that efforts to prevent initiation and promote

ALL-IN-ONE LASER SCANNING METHODS FOR SURVEYING, REPRESENTING AND SHARING INFORMATION ON ARCHAEOLOGY. VIA FLAMINIA AND THE FURLO TUNNEL COMPLEX

Directory of Open Access Journals (Sweden)

P. Clini

2013-07-01

Full Text Available The aim of this paper is to describe the results of the laser scanner survey of an archaeological complex, aimed at knowledge, documentation and diagnostic operations to make premises secure. Archaeology has always been the most complex subject where the discipline of surveying is continually being put to the test and experimented with. The development in laser scanner technologies has led to an extremely important turning point in this field. Complex geometrical shapes or irregular surfaces, such as those in archaeology, are defined through surfaces that can be directly extrapolated from the point cloud with extremely high precision, allowing even the finest details to be mapped. The precision of this surveying technique together with the wide range of data that can be acquired and represented provide several opportunities for communication and investigation. This experimental work has concentrated on the Furlo tunnel complex, located along one of the most important infrastructural arteries from Roman antiquity, the Via Flaminia. The need in this case was to be able to acquire the entire rocky complex, extending the scan area as far as possible so as to assess the whole system in its entirety. The results of our metric and morphological survey provide an excellent basis for record the situation as it is today, so as to establish the initial temporal step to be used in future monitoring programmes. The accuracy of the survey allows static assessments and effective planning for future safety-oriented projects.

Although gestational surrogacy offers several advantages, this procedure has given rise to some ethical and legal issues. We aimed to clarify the factors affecting the attitude of the Japanese toward gestational surrogacy. Cross-sectional study. Nationwide opinion surveys concerning assisted reproductive technologies (ART) were carried out in 1999 and 2003. Participants included 2568 and 3647 people from the general public surveyed in 1999 and 2003, respectively (1564 people received only the questionnaire, and 2083 people received a questionnaire and brochure about ART). Multivariate-adjusted odds ratio and 95% confidence interval from logistic regression models for factors affecting the attitude toward gestational surrogacy. In both surveys, approximately half of respondents approved of gestational surrogacy; 20-30% disapproved of the procedure. People with high socioeconomic status clearly expressed their opinion on this issue. A liberal attitude toward gender role promoted approval of gestational surrogacy; a liberal attitude toward family had the opposite effect. Our findings suggest that socioeconomic status affects people's expression of their opinion regarding this issue, while attitudes toward this procedure were influenced by individual belief. Considering socioeconomic status and diversity of individual belief is required for further discussion on this topic.

A self-administered questionnaire covering (1) personal data, (2) lifestyle, (3) mental health status, and (4) feelings of anger and impulsivity was distributed to junior and senior high school students in Japan. Among the total of 10,955 junior high schools and 5,115 senior high schools nationwide, 130 and 110 were randomly selected, respectively. Of those, 92 junior and 80 senior high schools participated in the survey. The survey period was from December 2008 to the end of January 2009. A total of 95,680 questionnaires were collected. After excluding invalid responses, the remaining 94,777 responses (response rate: 62.3%) were analyzed. From the questions regarding anger and impulsivity, 8.7% (95% CI, 8.5%-8.9%) and 7.5% (95% CI, 7.3%-7.7%) of the participants were considered to have experienced intense anger and impulsivity, respectively. Logistic regression analysis indicated that the odds ratios for experiencing intense feelings of anger were significantly higher (all P values breakfast, did not wish to go to university, had short sleep duration, had decreased positive feelings, had increased depressive feelings, or used mobile phones for longer hours. The odds ratios for experiencing intense impulsivity were significantly higher among students who smoked, consumed alcohol, skipped breakfast, did not participate in club activities, had short sleep duration, had decreased positive feelings, had increased depressive feelings, or used mobile phones for longer hours. The results suggest that healthy lifestyle habits, good sleep habits, and improved mental health are important for preventing intense feelings of anger and impulsivity among adolescents. © Copyright 2016 Physicians Postgraduate Press, Inc.

Since the initial inclusion of PTSD in the DSM nomenclature, PTSD symptomatology has been distributed across three symptom clusters. However, a wealth of empirical research has concluded that PTSD's latent structure is best represented by one of two four-factor models: Numbing or Dysphoria. Recently, a newly proposed five-factor Dysphoric Arousal model, which separates the DSM-IV's Arousal cluster into two factors of Anxious Arousal and Dysphoric Arousal, has gathered support across a variety of trauma samples. To date, the Dysphoric Arousal model has not been assessed using nationally representative epidemiological data. We employed confirmatory factor analysis to examine PTSD's latent structure in two independent population based surveys from American (NESARC) and Australia (NSWHWB). We specified and estimated the Numbing model, the Dysphoria model, and the Dysphoric Arousal model in both samples. Results revealed that the Dysphoric Arousal model provided superior fit to the data compared to the alternative models. In conclusion, these findings suggest that items D1-D3 (sleeping difficulties; irritability; concentration difficulties) represent a separate, fifth factor within PTSD's latent structure using nationally representative epidemiological data in addition to single trauma specific samples.

Post-communist countries have experienced rapid economic development and social changes, which have been accompanied by changes in health-related lifestyle behaviors, such as physical activity. The purpose of this study was to examine the associations of domain-specific physical activity and total sedentary time with BMI among adults in the Czech Republic. We surveyed a nationally representative sample (n = 4097) of the Czech Republic in fall 2007 using the International Physical Activity Questionnaire (long form). Multiple linear regression analyses were used to examine associations of physical activity, sedentary time and sociodemographic characteristics with BMI. Older age, lower educational attainment, and lower levels of leisure-time physical activity were associated with higher BMI. Compared with those living in large cities, men living in small towns and women living in small villages had higher BMI. This study has identified correlates of BMI in the Czech Republic. Although more evidence from longitudinal studies is needed, findings from the current study can inform interventions to prevent the rising obesity epidemic.

Racialized identity and health in Canada: results from a nationally representative survey.

Science.gov (United States)

Veenstra, Gerry

2009-08-01

This article uses survey data to investigate health effects of racialization in Canada. The operative sample was comprised of 91,123 Canadians aged 25 and older who completed the 2003 Canadian Community Health Survey. A "racial and cultural background" survey question contributed a variable that differentiated respondents who identified with Aboriginal, Black, Chinese, Filipino, Latin American, South Asian, White, or jointly Aboriginal and White racial/cultural backgrounds. Indicators of diabetes, hypertension and self-rated health were used to assess health. The healthy immigrant effect suppressed some disparity in risk for diabetes by racial/cultural identification. In logistic regression models also containing gender, age, and immigrant status, no racial/cultural identifications corresponded with significantly better health outcomes than those reported by survey respondents identifying as White. Subsequent models indicated that residential locale did little to explain the associations between racial/cultural background and health and that socioeconomic status was only implicated in relatively poor health outcomes for respondents identifying as Aboriginal or Aboriginal/White. Sizable and statistically significant relative risks for poor health for respondents identifying as Aboriginal, Aboriginal/White, Black, Chinese, or South Asian remained unexplained by the models, suggesting that other explanations for health disparities by racialized identity in Canada - perhaps pertaining to experiences with institutional racism and/or the wear and tear of experiences of racism and discrimination in everyday life - also deserve empirical investigation in this context.

In Australia telephone surveys have been the method of choice for ongoing jurisdictional population health surveys. Although it was estimated in 2011 that nearly 20% of the Australian population were mobile-only phone users, the inclusion of mobile phone numbers into these existing landline population health surveys has not occurred. This paper describes the methods used for the inclusion of mobile phone numbers into an existing ongoing landline random digit dialling (RDD) health survey in an Australian state, the New South Wales Population Health Survey (NSWPHS). This paper also compares the call outcomes, costs and the representativeness of the resultant sample to that of the previous landline sample. After examining several mobile phone pilot studies conducted in Australia and possible sample designs (screening dual-frame and overlapping dual-frame), mobile phone numbers were included into the NSWPHS using an overlapping dual-frame design. Data collection was consistent, where possible, with the previous years' landline RDD phone surveys and between frames. Survey operational data for the frames were compared and combined. Demographic information from the interview data for mobile-only phone users, both, and total were compared to the landline frame using χ2 tests. Demographic information for each frame, landline and the mobile-only (equivalent to a screening dual frame design), and the frames combined (with appropriate overlap adjustment) were compared to the NSW demographic profile from the 2011 census using χ2 tests. In the first quarter of 2012, 3395 interviews were completed with 2171 respondents (63.9%) from the landline frame (17.6% landline only) and 1224 (36.1%) from the mobile frame (25.8% mobile only). Overall combined response, contact and cooperation rates were 33.1%, 65.1% and 72.2% respectively. As expected from previous research, the demographic profile of the mobile-only phone respondents differed most (more that were young, males, Aboriginal

The aim of the present study was to analyze the relationship between bereavement and alcohol consumption accounting for time and gender differences on a nationally representative sample from Hungary ("Hungarostudy Epidemiological Panel Survey", N = 4457 Methods Drinking characteristics of mourning persons (alcohol consumption, dependence symptoms, and harmful consequences of alcohol use in the first three years of grief were examined among persons between 18-75 years using the Alcohol Use Disorders Identification Test (AUDIT. Results Men bereaved for one year scored higher on two dimensions of AUDIT (dependence symptoms and harmful alcohol use, while men bereaved for two years scored higher on all three dimensions of AUDIT compared to the non-bereaved. The rate of men clinically at-risk concerning alcohol consumption among the non-bereaved is 12.9%, and among men bereaved for one year is 18.4% (a non-significant difference, while 29.8% (p Conclusion Among bereaved men, the risk of alcohol related problems tends to be higher, which can be shown both among men bereaved for one year as well as men bereaved for two years. Considering the higher morbidity and mortality rates of bereaved men, alcohol consumption might play a mediator role. These facts draw attention to the importance of prevention, early recognition, and effective therapy of hazardous drinking in bereaved men.

We examined smoking cessation rate by education and determined how much of the difference can be attributed to the rate of quit attempts and how much to the success of these attempts. We analyzed data from the National Health Interview Survey (NHIS, 1991-2010) and the Tobacco Use Supplement to the Current Population Survey (TUS-CPS, 1992-2011). Smokers (≥ 25 years) were divided into lower- and higher-education groups (≤ 12 years and >12 years). A significant difference in cessation rate between the lower- and the higher-education groups persisted over the last 2 decades. On average, the annual cessation rate for the former was about two thirds that of the latter (3.5% vs 5.2%; Peducation group have consistently lagged behind their higher-education counterparts in quitting. In addition to the usual concern about improving their success in quitting, tobacco control programs need to find ways to increase quit attempts in this group.

Evidence shows that smoking tobacco using a waterpipe is significantly associated with diseases. Despite this, waterpipe use seems to be increasing worldwide, though nationally representative data are not widely available. The Global Adult Tobacco Survey (GATS) provides an opportunity to measure various indicators of waterpipe use from nationally representative surveys. Data were obtained for adults 15 years of age or older from 13 countries (Bangladesh, Brazil, China, Egypt, India, Mexico, Philippines, Russia, Thailand, Turkey, Ukraine, Uruguay and Vietnam) who completed GATS from 2008-2010. The GATS questionnaire collected data on current waterpipe use, including daily/less than daily prevalence and number of sessions per day/week. An optional waterpipe module measured former use, age of initiation, and level of consumption during a session. GATS was successful in producing nationally representative data on waterpipe use from 13 countries, many of which for the first time. The prevalence of waterpipe use among men was highest in Vietnam (13.0%) and Egypt (6.2%); among women, waterpipe use was highest in Russia (3.2%) and Ukraine (1.1%). While over 90% of adults in Ukraine thought smoking tobacco causes serious illness, only 31.4% thought smoking tobacco using a waterpipe causes serious illness. GATS data provide the ability to analyse waterpipe use within a country and across countries. Monitoring of waterpipe use at a national level will better enable countries to target tobacco control interventions such as education campaigns about the negative health effects of waterpipe use.

Contribution of correlated noise and selective decoding to choice probability measurements in extrastriate visual cortex.

Science.gov (United States)

Gu, Yong; Angelaki, Dora E; DeAngelis, Gregory C

2014-07-01

Trial by trial covariations between neural activity and perceptual decisions (quantified by choice Probability, CP) have been used to probe the contribution of sensory neurons to perceptual decisions. CPs are thought to be determined by both selective decoding of neural activity and by the structure of correlated noise among neurons, but the respective roles of these factors in creating CPs have been controversial. We used biologically-constrained simulations to explore this issue, taking advantage of a peculiar pattern of CPs exhibited by multisensory neurons in area MSTd that represent self-motion. Although models that relied on correlated noise or selective decoding could both account for the peculiar pattern of CPs, predictions of the selective decoding model were substantially more consistent with various features of the neural and behavioral data. While correlated noise is essential to observe CPs, our findings suggest that selective decoding of neuronal signals also plays important roles.

Whether a mixed type of craniopharyngioma (CP) exists and whether papillary craniopharyngioma (pCP) is on a histopathological continuum with Rathke's cleft cyst (RCC) remain controversial. Herein, we examined the expression and localization of β-catenin, BRAF p.V600E (V600E), and triggering receptor expressed on myeloid cells-1 (TREM-1) in 58 samples including 20 pCPs, 26 adamantinomatous craniopharyngiomas (aCP), and 12 RCCs. Five aCPs were diagnosed with mixed type CPs and the remaining 21 cases were pure aCPs. Four of the 12 RCCs presented with significant squamous epithelium (SE). V600E immunoreactivity was observed in all pCPs in the cytoplasm, but not in the nuclei. aCPs and RCCs, including mixed type CP, did not express V600E. Nuclear β-catenin translocation was detected exclusively in aCPs. TREM-1 was expressed in pCPs. Additionally, TREM-1 expression was detected in the SE of 5 "mixed type" CPs, while it was absent in pure aCPs. TREM-1 was expressed in 4 RCCs with SE, but not in the remaining 8 RCCs. TREM-1 mRNA levels were compared in cultured pCP and aCP cells. TREM-1 mRNA level was significantly (p < 0.001; up to 4.045 fold) higher in pCPs than in aCPs. Western blotting revealed a significantly (p < 0.001; up to 7.19 fold) lower level of TREM-1 expression in aCP cells compared to that in pCP cells. Our findings further supported that RCC and pCP may represent two ends of a morphological spectrum. A variant showing overlapping histological features of aCP and pCP should not be considered as a mixed type.

The future prospect of PV and CSP solar technologies: An expert elicitation survey

Bosetti, Valentina; Catenacci, Michela; Fiorese, Giulia; Verdolini, Elena

2012-01-01

In this paper we present and discuss the results of an expert elicitation survey on solar technologies. Sixteen leading European experts from the academic world, the private sector and international institutions took part in this expert elicitation survey on Photovoltaic (PV) and Concentrated Solar Power (CSP) technologies. The survey collected probabilistic information on (1) how Research, Development and Demonstration (RD and D) investments will impact the future costs of solar technologies and (2) the potential for solar technology deployment both in OECD and non-OECD countries. Understanding the technological progress and the potential of solar PV and CPS technologies is crucial to draft appropriate energy policies. The results presented in this paper are thus relevant for the policy making process and can be used as better input data in integrated assessment and energy models. - Highlights: ► With constant public support at least one solar technology will become cost-competitive with fossil fuels. ► Demonstration should become a key area of funding. ► Without climate policy (carbon price), by 2030 solar technologies will not be cost-competitive. ► The EU will first achieve a breakthrough in production costs. ► The share of electricity production from solar will never exceed 30%.

To determine the prevalence of suicidal ideation among Métis men and women (20-59 years) and identify its associated risk and protective factors using data from the nationally representative Aboriginal Peoples Survey (2006). Secondary analysis of previously collected data from a nationally representative cross-sectional survey. Across Canada, lifetime suicidal ideation was reported by an estimated 13.3% (or an estimated 34,517 individuals) of the total population of 20-to-59-year-old Métis. Of those who ideated, 46.2% reported a lifetime suicide attempt and 6.0% indicated that they had attempted suicide in the previous 12 months. Prevalence of suicidal ideation was higher among Métis men than in men who did not report Aboriginal identity in examined jurisdictions. Métis women were more likely to report suicidal ideation compared with Métis men (14.9% vs. 11.5%, respectively). Métis women and men had some common associated risk and protective factors such as major depressive episode, history of self-injury, perceived Aboriginal-specific community issues, divorced status, high mobility, self-rated thriving health, high self-esteem and positive coping ability. However, in Métis women alone, heavy frequent drinking, history of foster care experience and lower levels of social support were significant associated risk factors of suicidal ideation. Furthermore, a significant interaction was observed between social support and major depressive episode. Among Métis men, history of ever smoking was the sole unique associated risk factor. The higher prevalence of suicidal ideation among Métis women compared with Métis men and the observed gender differences in associations with some associated risk and protective factors suggest the need for gender-responsive programming to address suicidal ideation.

Full Text Available A multi-site evaluation (survey of five Kellogg-funded Community Partnerships (CPs in South Africa was undertaken to explore the relationship between leadership skills and a range of 30 operational, functional and organisational factors deemed critical to successful CPs. The CPs were collaborative academic-health service-community efforts aimed at health professions education reforms. The level of agreement to eleven dichotomous (‘Yes/No’ leadership skills items was used to compute two measures of members’ appreciation of their CPs’ leadership. The associations between these measures and 30 CPs factors were explored, and the partnership factors that leadership skills explained were assessed after controlling. Respondents who perceived the leadership of their CPs favourably had more positive ratings across 30 other artnership factors than those who rated leadership skills less favourably, and were more likely to report a positive cost/benefit ratio. In addition, respondents who viewed their CPs’ leadership positively also rated the operational understanding, the communication mechanisms, as well as the rules and procedures of the CPs more favourably. Leadership skills explained between 20% and 7% of the variance of 10 partnership factors. The influence of leaders’ skills in effective healthfocussed partnerships is much broader than previously conceptualised.

Providing patient care in community pharmacies in Australia.

To describe Australia's community pharmacy network in the context of the health system and outline the provision of services. The 5000 community pharmacies form a key component of the healthcare system for Australians, for whom health expenditures represent 9% of the Gross Domestic Product. A typical community pharmacy dispenses 880 prescriptions per week. Pharmacists are key partners in the Government's National Medicines Policy and contribute to its objectives through the provision of cognitive pharmaceutical services (CPS). The Third Community Pharmacy Agreement included funding for CPS including medication review and the provision of written drug information. Funding is also provided for a quality assurance platform with which the majority of pharmacies are accredited. Fifteen million dollars (Australian) have been allocated to research in community pharmacy, which has focused on achieving quality use of medicines (QUM), as well as developing new CPS and facilitating change. Elements of the Agreements have taken into account QUM principles and are now significant drivers of practice change. Although accounting for 10% of remuneration for community pharmacy, the provision of CPS represents a significant shift in focus to view pharmacy as a service provider. Delivery of CPS through the community pharmacy network provides sustainability for primary health care due to improvement in quality presumably associated with a reduction in healthcare costs. Australian pharmacy practice is moving strongly in the direction of CPS provision; however, change does not occur easily. The development of a change management strategy is underway to improve the uptake of professional and business opportunities in community pharmacy.

2014-01-01

CMOS pixel sensors (CPS) represent a novel technological approach to building charged particle detectors. CMOS processes allow to integrate a sensing volume and readout electronics in a single silicon die allowing to build sensors with a small pixel pitch ($\\sim 20 \\mu m$) and low material budget ($\\sim 0.2-0.3\\% X_0$) per layer. These characteristics make CPS an attractive option for vertexing and tracking systems of high energy physics experiments. Moreover, thanks to the mass production industrial CMOS processes used for the manufacturing of CPS the fabrication construction cost can be significantly reduced in comparison to more standard semiconductor technologies. However, the attainable performance level of the CPS in terms of radiation hardness and readout speed is mostly determined by the fabrication parameters of the CMOS processes available on the market rather than by the CPS intrinsic potential. The permanent evolution of commercial CMOS processes towards smaller feature sizes and high resistivity ...

Socioeconomic Inequality in mortality using 12-year follow-up data from nationally representative surveys in South Korea.

Investigations into socioeconomic inequalities in mortality have rarely used long-term mortality follow-up data from nationally representative samples in Asian countries. A limited subset of indicators for socioeconomic position was employed in prior studies on socioeconomic inequalities in mortality. We examined socioeconomic inequalities in mortality using follow-up 12-year mortality data from nationally representative samples of South Koreans. A total of 10,137 individuals who took part in the 1998 and 2001 Korea National Health and Nutrition Examination Surveys were linked to mortality data from Statistics Korea. Of those individuals, 1,219 (12.1 %) had died as of December 2012. Cox proportional hazard models were used to estimate the relative risks of mortality according to a wide range of socioeconomic position (SEP) indicators after taking into account primary sampling units, stratification, and sample weights. Our analysis showed strong evidence that individuals with disadvantaged SEP indicators had greater all-cause mortality risks than their counterparts. The magnitude of the association varied according to gender, age group, and specific SEP indicators. Cause-specific analyses using equivalized income quintiles showed that the magnitude of mortality inequalities tended to be greater for cardiovascular disease and external causes than for cancer. Inequalities in mortality exist in every aspect of SEP indicators, both genders, and age groups, and four broad causes of deaths. The South Korean economic development, previously described as effective in both economic growth and relatively equitable income distribution, should be scrutinized regarding its impact on socioeconomic mortality inequalities. Policy measures to reduce inequalities in mortality should be implemented in South Korea.

In Streptococcus agalactiae, the capsular polysaccharide (CPS) is recognized as a major virulence factor while the group B carbohydrate (GBC) is crucial for peptidoglycan biosynthesis and cell division. Despite the important roles of CPS and GBC, there is little information available on the molecular organization of these glycopolymers on the cell surface. Here, we use atomic force microscopy (AFM) and transmission electron microscopy (TEM) to analyze the nanoscale distribution of CPS and GBC in wild-type (WT) and mutant strains of S. agalactiae. TEM analyses reveal that in WT bacteria, peptidoglycan is covered with a very thin (few nm) layer of GBC (the ``pellicle'') overlaid by a 15-45 nm thick layer of CPS (the ``capsule''). AFM-based single-molecule mapping with specific antibody probes shows that CPS is exposed on WT cells, while it is hardly detected on mutant cells impaired in CPS production (ΔcpsE mutant). By contrast, both TEM and AFM show that CPS is over-expressed in mutant cells altered in GBC expression (ΔgbcO mutant), indicating that the production of the two surface glycopolymers is coordinated in WT cells. In addition, AFM topographic imaging and molecular mapping with specific lectin probes demonstrate that removal of CPS (ΔcpsE), but not of GBC (ΔgbcO), leads to the exposure of peptidoglycan, organized into 25 nm wide bands running parallel to the septum. These results indicate that CPS forms a homogeneous barrier protecting the underlying peptidoglycan from environmental exposure, while the presence of GBC does not prevent peptidoglycan detection. This work shows that single-molecule AFM, combined with high-resolution TEM, represents a powerful platform for analysing the molecular arrangement of the cell wall polymers of bacterial pathogens.

Although men have substantial decision-making power regarding condom use, the majority of HIV knowledge and prevention studies in the general Haitian population have been conducted among youth and women. We investigated attitudes towards intimate partner violence, knowledge of and use of condoms among 9,493 men in Haiti using data from the 2012 nationally representative Demographic and Health Survey. Only 36% of HIV-negative and 44% of HIV-positive men reported using a condom the last time th...

Limited information is available regarding the profile and clinical practice characteristics of the osteopathy workforce in Australia. This paper reports such information by analysing data from a nationally-representative sample of Australian osteopaths. Data was obtained from a workforce survey of Australian osteopathy, investigating the characteristics of the practitioner, their practice, clinical management features and perceptions regarding research. The survey questionnaire was distributed to all registered osteopaths across Australia in 2016 as part of the Osteopathy Research and Innovation Network (ORION) project. A total of 992 Australian osteopaths participated in this study representing a response rate of 49.1%. The average age of the participants was 38.0 years with 58.1% being female and the majority holding a Bachelor or higher degree qualification related to the osteopathy professional. Approximately 80.0% of the osteopaths were practicing in an urban area, with most osteopaths working in multi-practitioner locations, having referral relationships with a range of health care practitioners, managing patients a number of musculoskeletal disorders, and providing multi-model treatment options. A total of 3.9 million patients were estimated to consult with osteopaths every year and an average of approximate 3.0 million hours were spent delivering osteopathy services per year. Further research is required to provide rich, in-depth examination regarding a range of osteopathy workforce issues which will help ensure safe, effective patient care to all receiving and providing treatments as part of the broader Australian health system.

Full Text Available Individual skin health attitudes are influenced by various factors, including public education campaigns, mass media, family, and friends. Evidence-based, educative information materials assist communication and decision-making in doctor-patient interactions. The present study aims at assessing the prevailing use of skin health information material and sources and their impact on skin health knowledge, motives to tan, and sun protection. We conducted a questionnaire survey among a representative sample of Austrian residents. Print media and television were perceived as the two most relevant sources for skin health information, whereas the source physician was ranked third. Picking the information source physician increased participants’ skin health knowledge (p = 0.025 and sun-protective behavior (p < 0.001. The study results highlight the demand for targeted health messages to attain lifestyle changes towards photo-protective habits. Providing resources that encourage pro-active counseling in every-day doctor-patient communication could increase skin health knowledge and sun-protective behavior, and thus, curb the rise in skin cancer incidence rates.

Nutrition and health claims on foods can help consumers make healthier food choices. However, claims may have a ‘halo’ effect, influencing consumer perceptions of foods and increasing consumption. Evidence for these effects are typically demonstrated in experiments with small samples, limiting generalisability. The current study aimed to overcome this limitation through the use of a nationally representative survey. In a cross-sectional survey of 1039 adults across the island of Ireland, respondents were presented with three different claims (nutrition claim = “Low in fat”; health claim = “With plant sterols. Proven to lower cholesterol”; satiety claim = “Fuller for longer”) on four different foods (cereal, soup, lasagne, and yoghurt). Participants answered questions on perceived healthiness, tastiness, and fillingness of the products with different claims and also selected a portion size they would consume. Claims influenced fillingness perceptions of some of the foods. However, there was little influence of claims on tastiness or healthiness perceptions or the portion size selected. Psychological factors such as consumers’ familiarity with foods carrying claims and belief in the claims were the most consistent predictors of perceptions and portion size selection. Future research should identify additional consumer factors that may moderate the relationships between claims, perceptions, and consumption. PMID:29789472

The objective of this study was to assess the risk of lung cancer mortality in a nationally representative sample of U.S. workers by occupation. National Death Index linkage identified 1812 lung cancer deaths among 143,863 workers who participated in the 1987, 1988, and 1990-1994 National Health Interview Surveys. Current and former smoking status was predictive of lung cancer mortality (hazard ratio [HR] = 15.1 and 3.8, respectively). Occupations with significantly higher risk for age- and smoking-adjusted lung cancer mortality included heating/air/refrigeration mechanics (HR = 3.0); not specified mechanics and repairers (HR = 2.8); financial records processing occupations (HR = 1.8); freight, stock, and materials handlers (HR = 1.5); and precision production occupations (HR = 1.4). Although tobacco use continues to be the single most important risk factor for lung cancer mortality, occupational exposure to lung carcinogens should be targeted as well to further reduce the burden of lung cancer.

Sleepiness and Motor Vehicle Crashes in a Representative Sample of Portuguese Drivers: The Importance of Epidemiological Representative Surveys.

Sleepiness is considered to be a leading cause of crashes. Despite the huge amount of information collected in questionnaire studies, only some are based on representative samples of the population. Specifics of the populations studied hinder the generalization of these previous findings. For the Portuguese population, data from sleep-related car crashes/near misses and sleepiness while driving are missing. The objective of this study is to determine the prevalence of near-miss and nonfatal motor vehicle crashes related to sleepiness in a representative sample of Portuguese drivers. Structured phone interviews regarding sleepiness and sleep-related crashes and near misses, driving habits, demographic data, and sleep quality were conducted using the Pittsburgh Sleep Quality Index and sleep apnea risk using the Berlin questionnaire. A multivariate regression analysis was used to determine the associations with sleepy driving (feeling sleepy or falling asleep while driving) and sleep-related near misses and crashes. Nine hundred subjects, representing the Portuguese population of drivers, were included; 3.1% acknowledged falling asleep while driving during the previous year and 0.67% recalled sleepiness-related crashes. Higher education, driving more than 15,000 km/year, driving more frequently between 12:00 a.m. and 6 a.m., fewer years of having a driver's license, less total sleep time per night, and higher scores on the Epworth Sleepiness Scale (ESS) were all independently associated with sleepy driving. Sleepiness-related crashes and near misses were associated only with falling asleep at the wheel in the previous year. Sleep-related crashes occurred more frequently in drivers who had also had sleep-related near misses. Portugal has lower self-reported sleepiness at the wheel and sleep-related near misses than most other countries where epidemiological data are available. Different population characteristics and cultural, social, and road safety specificities may

Engagement and Action for Health: The Contribution of Leaders’ Collaborative Skills to Partnership Success

Ansari, Walid El; Oskrochi, Reza; Phillips, Ceri

2009-01-01

A multi-site evaluation (survey) of five Kellogg-funded Community Partnerships (CPs) in South Africa was undertaken to explore the relationship between leadership skills and a range of 30 operational, functional and organisational factors deemed critical to successful CPs. The CPs were collaborative academic-health service-community efforts aimed at health professions education reforms. The level of agreement to eleven dichotomous (‘Yes/No’) leadership skills items was used to compute two measures of members’ appreciation of their CPs’ leadership. The associations between these measures and 30 CPs factors were explored, and the partnership factors that leadership skills explained were assessed after controlling. Respondents who perceived the leadership of their CPs favourably had more positive ratings across 30 other partnership factors than those who rated leadership skills less favourably, and were more likely to report a positive cost/ benefit ratio. In addition, respondents who viewed their CPs’ leadership positively also rated the operational understanding, the communication mechanisms, as well as the rules and procedures of the CPs more favourably. Leadership skills explained between 20% and 7% of the variance of 10 partnership factors. The influence of leaders’ skills in effective health-focussed partnerships is much broader than previously conceptualised. PMID:19440289

Full Text Available Objective. To determine the prevalence of suicidal ideation among Métis men and women (20–59 years and identify its associated risk and protective factors using data from the nationally representative Aboriginal Peoples Survey (2006. Study design. Secondary analysis of previously collected data from a nationally representative cross-sectional survey. Results. Across Canada, lifetime suicidal ideation was reported by an estimated 13.3% (or an estimated 34,517 individuals of the total population of 20-to-59-year-old Métis. Of those who ideated, 46.2% reported a lifetime suicide attempt and 6.0% indicated that they had attempted suicide in the previous 12 months. Prevalence of suicidal ideation was higher among Métis men than in men who did not report Aboriginal identity in examined jurisdictions. Métis women were more likely to report suicidal ideation compared with Métis men (14.9% vs. 11.5%, respectively. Métis women and men had some common associated risk and protective factors such as major depressive episode, history of self-injury, perceived Aboriginal-specific community issues, divorced status, high mobility, self-rated thriving health, high self-esteem and positive coping ability. However, in Métis women alone, heavy frequent drinking, history of foster care experience and lower levels of social support were significant associated risk factors of suicidal ideation. Furthermore, a significant interaction was observed between social support and major depressive episode. Among Métis men, history of ever smoking was the sole unique associated risk factor. Conclusion. The higher prevalence of suicidal ideation among Métis women compared with Métis men and the observed gender differences in associations with some associated risk and protective factors suggest the need for gender-responsive programming to address suicidal ideation.

Full Text Available Abstract Background Cyclopropane fatty acids (CPA have been found in certain gymnosperms, Malvales, Litchi and other Sapindales. The presence of their unique strained ring structures confers physical and chemical properties characteristic of unsaturated fatty acids with the oxidative stability displayed by saturated fatty acids making them of considerable industrial interest. While cyclopropenoid fatty acids (CPE are well-known inhibitors of fatty acid desaturation in animals, CPE can also inhibit the stearoyl-CoA desaturase and interfere with the maturation and reproduction of some insect species suggesting that in addition to their traditional role as storage lipids, CPE can contribute to the protection of plants from herbivory. Results Three genes encoding cyclopropane synthase homologues GhCPS1, GhCPS2 and GhCPS3 were identified in cotton. Determination of gene transcript abundance revealed differences among the expression of GhCPS1, 2 and 3 showing high, intermediate and low levels, respectively, of transcripts in roots and stems; whereas GhCPS1 and 2 are both expressed at low levels in seeds. Analyses of fatty acid composition in different tissues indicate that the expression patterns of GhCPS1 and 2 correlate with cyclic fatty acid (CFA distribution. Deletion of the N-terminal oxidase domain lowered GhCPS's ability to produce cyclopropane fatty acid by approximately 70%. GhCPS1 and 2, but not 3 resulted in the production of cyclopropane fatty acids upon heterologous expression in yeast, tobacco BY2 cell and Arabidopsis seed. Conclusions In cotton GhCPS1 and 2 gene expression correlates with the total CFA content in roots, stems and seeds. That GhCPS1 and 2 are expressed at a similar level in seed suggests both of them can be considered potential targets for gene silencing to reduce undesirable seed CPE accumulation. Because GhCPS1 is more active in yeast than the published Sterculia CPS and shows similar activity when expressed in model

Although cancer patients (CPs) are increasingly likely to visit emergency department (ED), no population-based study has compared the characteristics of CPs and non-cancer patients (NCPs) who visit the ED and examined factors associated with hospitalization via the ED. In this study, we (1) compared characteristics and diagnoses between CPs and NCPs who visited the ED in a cancer center or general hospital; (2) compared characteristics and diagnoses between CPs and NCPs who were hospitalized via the ED in a cancer center or general hospital; and (3) investigated important factors associated with such hospitalization. We analyzed patient characteristic and diagnosis [based on International Classification of Diseases-9 (ICD-9) codes] data from the ED of a comprehensive cancer center (MDACC), 24 general EDs in Harris County, Texas (HCED), and the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 1/1/2007-12/31/2009. Approximately 3.4 million ED visits were analyzed: 47,245, 3,248,973, and 104,566 visits for MDACC, HCED, and NHAMCS, respectively, of which 44,143 (93.4%), 44,583 (1.4%), and 632 (0.6%) were CP visits. CPs were older than NCPs and stayed longer in EDs. Lung, gastrointestinal (excluding colorectal), and genitourinary (excluding prostate) cancers were the three most common diagnoses related to ED visits at general EDs. CPs visiting MDACC were more likely than CPs visiting HCED to be privately insured. CPs were more likely than NCPs to be hospitalized. Pneumonia and influenza, fluid and electrolyte disorders, and fever were important predictive factors for CP hospitalization; coronary artery disease, cerebrovascular disease, and heart failure were important factors for NCP hospitalization. CPs consumed more ED resources than NCPs and had a higher hospitalization rate. Given the differences in characteristics and diagnoses between CPs and NCPs, ED physicians must pay special attention to CPs and be familiar with their unique set of oncologic

No recent original studies on the pattern of diet are available for Saudi Arabia at the national level. The present study was performed to describe the consumption of foods and beverages by Saudi adults. The Saudi Health Interview Survey (SHIS) was conducted in 2013. Data were collected through interviews and anthropometric measurements were done. A diet history questionnaire was used to determine the amount of consumption for eighteen food or beverage items in a typical week. The study was a household survey in all thirteen administrative regions of Saudi Arabia. Participants were 10 735 individuals aged 15 years or older. Mean daily consumption was 70·9 (se 1·3) g for fruits, 111·1 (se 2·0) g for vegetables, 11·6 (se 0·3) g for dark fish, 13·8 (se 0·3) g for other fish, 44·2 (se 0·7) g for red meat, 4·8 (se 0·2) g for processed meat, 10·9 (se 0·3) g for nuts, 219·4 (se 5·1) ml for milk and 115·5 (se 2·6) ml for sugar-sweetened beverages. Dietary guideline recommendations were met by only 5·2 % of individuals for fruits, 7·5 % for vegetables, 31·4 % for nuts and 44·7 % for fish. The consumption of processed foods and sugar-sweetened beverages was high in young adults. Only a small percentage of the Saudi population met the dietary recommendations. Programmes to improve dietary behaviours are urgently needed to reduce the current and future burden of disease. The promotion of healthy diets should target both the general population and specific high-risk groups. Regular assessments of dietary status are needed to monitor trends and inform interventions.

A study on the representative sampling survey for the inspection of the clearance level for the radioisotope waste

International Nuclear Information System (INIS)

2007-01-01

Utilization facilities for radioisotope (RI) are increasing annually in South Korea, and the total number was 2,723, as of December 31, 2005. The inspection of a clearance level is a very important problem in order to ensure a social reliance for releasing radioactive materials to the environment. Korean regulations for such a clearance are described in Notice No. 2001-30 of the Ministry of Science and Technology (MOST) and Notice No. 2002-67 of the Ministry of Commerce, Industry and Energy (MOCIE). Most unsealed sources in RI waste drums at a storage facility are low-level beta-emitters with short half-lives, so it is impossible to measure their inventories by a nondestructive analysis. Furthermore, RI wastes generated from hospital, educational and research institutes and industry have a heterogeneous, multiple, irregular, and a small quantity of a waste stream. This study addresses a representative (master) sampling survey and analysis plan for RI wastes because a complete enumeration of waste drums is impossible and not desirable in terms of a cost and efficiency. The existing approaches to a representative sampling include a judgmental, simple random, stratified random, systematic grid, systematic random, composite, and adaptive sampling. A representative sampling plan may combine two or more of the above sampling approaches depending on the type and distribution of a waste stream. Stratified random sampling (constrained randomization) is proven to be adequate for a sampling design of a RI waste regarding a half-life, surface dose, undertaking time to a storage facility, and type of waste. The developed sampling protocol includes estimating the number of drums within a waste stream, estimating the number of samples, and a confirmation of the required number of samples. The statistical process control for a quality assurance plan includes control charts and an upper control limit (UCL) of 95% to determine whether a clearance level is met or not. (authors)

Selective and genetic constraints on pneumococcal serotype switching.

Directory of Open Access Journals (Sweden)

Nicholas J Croucher

2015-03-01

Full Text Available Streptococcus pneumoniae isolates typically express one of over 90 immunologically distinguishable polysaccharide capsules (serotypes, which can be classified into "serogroups" based on cross-reactivity with certain antibodies. Pneumococci can alter their serotype through recombinations affecting the capsule polysaccharide synthesis (cps locus. Twenty such "serotype switching" events were fully characterised using a collection of 616 whole genome sequences from systematic surveys of pneumococcal carriage. Eleven of these were within-serogroup switches, representing a highly significant (p < 0.0001 enrichment based on the observed serotype distribution. Whereas the recombinations resulting in between-serogroup switches all spanned the entire cps locus, some of those that caused within-serogroup switches did not. However, higher rates of within-serogroup switching could not be fully explained by either more frequent, shorter recombinations, nor by genetic linkage to genes involved in β-lactam resistance. This suggested the observed pattern was a consequence of selection for preserving serogroup. Phenotyping of strains constructed to express different serotypes in common genetic backgrounds was used to test whether genotypes were physiologically adapted to particular serogroups. These data were consistent with epistatic interactions between the cps locus and the rest of the genome that were specific to serotype, but not serogroup, meaning they were unlikely to account for the observed distribution of capsule types. Exclusion of these genetic and physiological hypotheses suggested future work should focus on alternative mechanisms, such as host immunity spanning multiple serotypes within the same serogroup, which might explain the observed pattern.

Towards a Semantic Web of Things: A Hybrid Semantic Annotation, Extraction, and Reasoning Framework for Cyber-Physical System

Directory of Open Access Journals (Sweden)

Zhenyu Wu

2017-02-01

Full Text Available Web of Things (WoT facilitates the discovery and interoperability of Internet of Things (IoT devices in a cyber-physical system (CPS. Moreover, a uniform knowledge representation of physical resources is quite necessary for further composition, collaboration, and decision-making process in CPS. Though several efforts have integrated semantics with WoT, such as knowledge engineering methods based on semantic sensor networks (SSN, it still could not represent the complex relationships between devices when dynamic composition and collaboration occur, and it totally depends on manual construction of a knowledge base with low scalability. In this paper, to addresses these limitations, we propose the semantic Web of Things (SWoT framework for CPS (SWoT4CPS. SWoT4CPS provides a hybrid solution with both ontological engineering methods by extending SSN and machine learning methods based on an entity linking (EL model. To testify to the feasibility and performance, we demonstrate the framework by implementing a temperature anomaly diagnosis and automatic control use case in a building automation system.

Web of Things (WoT) facilitates the discovery and interoperability of Internet of Things (IoT) devices in a cyber-physical system (CPS). Moreover, a uniform knowledge representation of physical resources is quite necessary for further composition, collaboration, and decision-making process in CPS. Though several efforts have integrated semantics with WoT, such as knowledge engineering methods based on semantic sensor networks (SSN), it still could not represent the complex relationships between devices when dynamic composition and collaboration occur, and it totally depends on manual construction of a knowledge base with low scalability. In this paper, to addresses these limitations, we propose the semantic Web of Things (SWoT) framework for CPS (SWoT4CPS). SWoT4CPS provides a hybrid solution with both ontological engineering methods by extending SSN and machine learning methods based on an entity linking (EL) model. To testify to the feasibility and performance, we demonstrate the framework by implementing a temperature anomaly diagnosis and automatic control use case in a building automation system. Evaluation results on the EL method show that linking domain knowledge to DBpedia has a relative high accuracy and the time complexity is at a tolerant level. Advantages and disadvantages of SWoT4CPS with future work are also discussed.

Role of superconducting energy gap in extended BCS-Bose crossover theory

Chávez, I.; García, L. A.; de Llano, M.; Grether, M.

2017-10-01

The generalized Bose-Einstein condensation (GBEC) theory of superconductivity (SC) is briefly surveyed. It hinges on three distinct new ingredients: (i) Treatment of Cooper pairs (CPs) as actual bosons since they obey Bose statistics, in contrast to BCS pairs which do not obey Bose commutation relations; (ii) inclusion of two-hole Cooper pairs (2hCPs) on an equal footing with two-electron Cooper pairs (2eCPs), thus making this a complete boson-fermion (BF) model; and (iii) inclusion in the resulting ternary ideal BF gas with particular BF vertex interactions that drive boson formation/disintegration processes. GBEC subsumes as special cases both BCS (having its 50-50 symmetry of both kinds of CPs) and ordinary BEC theories (having no 2hCPs), as well as the now familiar BCS-Bose crossover theory. We extended the crossover theory with the explicit inclusion of 2hCPs and construct a phase diagram of Tc/TF versus n/nf, where Tc and TF are the critical and Fermi temperatures, n is the total number density and nf that of unbound electrons at T = 0. Also, with this extended crossover one can construct the energy gap Δ(T)/Δ(0) versus T/Tc for some elemental SCs by solving at least two equations numerically: a gap-like and a number equation. In 50-50 symmetry, the energy gap curve agrees quite well with experimental data. But ignoring 2hCPs altogether leads to the gap curve falling substantially below that with 50-50 symmetry which already fits the data quite well, showing that 2hCPs are indispensable to describe SCs.

Only a few studies have provided information on awareness, use, and harm perceptions of e-cigarettes in Europe. We fill the knowledge gap in Italy. We used data from a face-to-face survey conducted in 2013 of a sample of 3,000 individuals, representative of the Italian population aged ≥15 years (51.1 million inhabitants). Awareness of e-cigarettes was 91.1%; it was lowest among women (87.8%), the elderly (78.4%), those with less education (84.1%), and never-smokers (89.0%). Ever e-cigarette use was 6.8% overall and was inversely related to age, whereas no significant difference was observed according to sex. With regard to smoking status, 2.6% of never-smokers, 7.0% of ex-smokers, and 20.4% of current smokers tried the e-cigarette at least once. Regular e-cigarette use was 1.2% overall, 1.5% among men, and 0.9% among women, and it was highest among young (2.4%) and current smokers (3.7%). Among 36 e-cigarette regular users, 22.0% did not change their smoking habit, 67.7% reduced traditional cigarette consumption, and 10.4% quit smoking. After fewer than 3 years from the opening of the first Italian e-cigarette shop, more than 45 million Italians have heard about e-cigarettes, 3.5 million have tried e-cigaretts, and more than 600,000 Italians regularly use e-cigarettes. Three out of 4 e-cigarette users reported to have favorably modified their smoking habit; however, 90% of users did not quit smoking as a consequence of starting vaping e-cigarettes. Almost 900,000 Italian never-smokers, particularly young never-smokers, have tried this new and potentially addictive product at least once. © The Author 2014.

2015-06-01

Age-appropriate child restraints and rear seating dramatically reduce injury in vehicle crashes. Yet parents and caregivers struggle to comply with child passenger safety (CPS) recommendations, and frequently make mistakes when choosing and installing restraints. The purpose of this research was to evaluate various methods of framing CPS recommendations, and to examine the relative effectiveness on parents' knowledge, attitudes, and behavioral intentions related to best practices and proper use of child restraints. Emphasis framing is a persuasion technique that involves placing focus on specific aspects of the content in order to encourage or discourage certain interpretations of the content. A 5 (flyer group) X 2 (time) randomized experiment was conducted in which 300 parent participants answered a pre-survey, viewed one of four flyer versions or a no-education control version, and completed a post-survey. Surveys measured CPS knowledge, attitudes, perceptions of efficacy and risk, and behavioral intentions. The four flyers compared in this study all communicated the same CPS recommendations, but several versions were tested which each employed a different emphasis frame: (1) recommendations organized by the natural progression of seat types; (2) recommendations which focused on avoiding premature graduation; (3) recommendations which explained the risk-reduction rationale behind the information given; or (4) recommendations which were organized by age. In a fifth no-education (control) condition, participants viewed marketing materials. Analyses of covariance and pairwise comparisons indicated the risk-reduction rationale flyer outperformed other flyers for many subscales, and significantly differed from no-education control for the most subscales, including restraint selection, back seat knowledge, rear-facing knowledge and attitudes, total efficacy, overall attitudes, and stated intentions. This research provides insight for increasing caregiver understanding

The concept of meaning in life (MIL) has become a central one in recent years, particularly in psycho-oncology and palliative care. The Schedule for Meaning in Life Evaluation (SMILE) has been developed to allow individuals to choose the life areas that they consider to be important for their own MIL. This approach relates to the "World Health Organisation" definition of quality of life (QOL) as an individual's perception of his own position. The aims of this study were (i) to assess MIL in a representative sample of the Swiss population according to the three linguistic regions and (ii) to evaluate whether MIL constitutes a significant determinant of the perceived QOL. A telephone survey of the Swiss population, performed by a professional survey company, was conducted between November and December 2013. The interview included the SMILE, perceived QOL (0-10) and health status (1-5), and various sociodemographic variables. In the SMILE, an index of weighting (IOW, 20-100), an index of satisfaction (IOS, 0-100), and a total SMILE index (IOWS, 0-100) are calculated from the areas mentioned by the participants as providing MIL. Among the 6671 telephonic contacts realized, 1015 (15%) participants completed the survey: 405 French, 400 German and 210 Italian participants. "Family" (80.2%), "occupation/work" (51%), and "social relations" (43.3%) were the most cited MIL-relevant categories. Italian participants listed "health" more frequently than German and French participants (50.4% vs 31.5% and 24.8% respectively, χ(2) = 12.229, p = .002). Age, gender, education, employment, and marital status significantly influenced either the MIL scores or the MIL-relevant categories. Linear regression analyses indicate that 24.3% of the QOL variance (p = .000) is explained by health status (B = .609, IC = .490-.728, p = .000), MIL (B = .034, IC = .028-.041, p = .000) and socioeconomic status (F = 11.01, p = .000).

Dental visits represent an opportunity to identify and help patients quit smoking, yet dental settings remain an untapped venue for treatment of tobacco dependence. The purpose of this analysis was to assess factors that may influence patterns of tobacco-use-related practice among a national sample of dental providers. We surveyed a representative sample of general dentists practicing in the United States (N = 1,802). Multivariable analysis was used to assess correlates of adherence to tobacco use treatment guidelines and to analyze factors that influence providers' willingness to offer tobacco cessation assistance if reimbursed for this service. More than 90% of dental providers reported that they routinely ask patients about tobacco use, 76% counsel patients, and 45% routinely offer cessation assistance, defined as referring patients for cessation counseling, providing a cessation prescription, or both. Results from multivariable analysis indicated that cessation assistance was associated with having a practice with 1 or more hygienists, having a chart system that includes a tobacco use question, having received training on treating tobacco dependence, and having positive attitudes toward treating tobacco use. Providers who did not offer assistance but who reported that they would change their practice patterns if sufficiently reimbursed were more likely to be in a group practice, treat patients insured through Medicaid, and have positive attitudes toward treating tobacco dependence. Findings indicate the potential benefit of increasing training opportunities and promoting system changes to increase involvement of dental providers in conducting tobacco use treatment. Reimbursement models should be tested to assess the effect on dental provider practice patterns.

Development of generic floor response spectra for equipment qualification for seismic loads

International Nuclear Information System (INIS)

Curren, J.R.; Costantino, C.J.

1984-01-01

A generic floor response spectra has been developed for use in the qualification of electrical and mechanical equipment in operating nuclear power plants. Actual PWR and BWR - Mark I structural models were used as representative of a class of structures. For each model, the stiffness properties were varied, with the same mass, so as to extend the fundamental base structure natural frequency from 2 cps to 36 cps. This resulted in fundamental mode coupled natural frequencies as low as 0.86 cps and as high as 30 cps. The characteristics of 1000 floor response spectra were studied to determine the generic spectra. A procedure for its application to any operating plant has been established. The procedure uses as much or as little information that currently exists at the plant relating to the question of equipment qualification. A generic floor response spectra is proposed for the top level of a generic structure. Reduction factors are applied to the peak acceleration for equipment at lower levels

Government agencies, public health organisations and tobacco control researchers rely on accurate estimates of cigarette prices for a variety of purposes. Since the 1950s, the Tax Burden on Tobacco (TBOT) has served as the most widely used source of this price data despite its limitations. This paper compares the prices and collection methods of the TBOT retail-based data and the 2003 and 2006/2007 waves of the population-based Tobacco Use Supplement to the Current Population Survey (TUS-CPS). From the TUS-CPS, we constructed multiple state-level measures of cigarette prices, including weighted average prices per pack (based on average prices for single-pack purchases and average prices for carton purchases) and compared these with the weighted average price data reported in the TBOT. We also constructed several measures of tax avoidance from the TUS-CPS self-reported data. For the 2003 wave, the average TUS-CPS price was 71 cents per pack less than the average TBOT price; for the 2006/2007 wave, the difference was 47 cents. TUS-CPS and TBOT prices were also significantly different at the state level. However, these differences varied widely by state due to tax avoidance opportunities, such as cross-border purchasing. The TUS-CPS can be used to construct valid measures of cigarette prices. Unlike the TBOT, the TUS-CPS captures the effect of price-reducing marketing strategies, as well as tax avoidance practices and non-traditional types of purchasing. Thus, self-reported data like TUS-CPS appear to have advantages over TBOT in estimating the 'real' price that smokers face. Published by the BMJ Publishing Group Limited.

Attitudes of the German general population toward early diagnosis of dementia--results of a representative telephone survey.

Directory of Open Access Journals (Sweden)

Tobias Luck

Full Text Available BACKGROUND: Early detection of dementia has clearly improved. Even though none of the currently available treatments for the most common form of dementia, Alzheimer's dementia, promises a cure, early diagnosis provides several benefits for patients, caregivers, and health care systems. This study aimed to describe attitudes toward early diagnosis of dementia in the German general population. METHODS: A representative telephone survey of the German population aged 18+ years (n = 1,002 was conducted in 2011. RESULTS: The majority of respondents (69% would be willing to be examined for early diagnosis of dementia. Almost two thirds reported that they would prefer their general practitioner (GP as the first source of professional help. More than half of the respondents (55% stated their belief that dementia could be prevented. Respondents mostly indicated psychosocial prevention options. CONCLUSIONS: Our findings suggest that the general population in Germany is very open to early diagnosis of dementia; however, this seems connected with large expectations on the effectiveness of prevention options. Dementia awareness campaigns may be employed to carefully inform the public about the prevention options currently available and their efficacy. To exploit GPs' potential as a gatekeeper for early detection of dementia, their ability to identify patients with antecedent and mild stages of the disease must be improved.

Could information about herd immunity help us achieve herd immunity? Evidence from a population representative survey experiment.

Immunisation causes dramatic reductions in morbidity and mortality from infectious diseases; however, resistance to vaccination is nonetheless widespread. An understudied issue - explored here - is whether appeals to collective as opposed to individual benefits of vaccination encourage people to vaccinate. Knowledge of this is important not least with respect to the design of public health campaigns, which often lack information about the collective benefits of vaccination. Using a between-subjects experimental survey design, we test whether information about the effects of herd immunity influences people's decision to vaccinate. A representative sample of Norwegians was confronted with a hypothetical scenario in which a new and infectious disease is on its way to Norway. The sample was split in three - a control group and two treatment groups. The one treatment group was provided information about collective benefits of vaccination; the other was provided information about the individual benefits of vaccination. Both treatments positively affect people's decision to vaccinate; however, informing about the collective benefits has an even stronger effect than informing about the individual benefits. Our results suggest that people's decision about whether to vaccinate and thus contribute to herd immunity is influenced by concern for others. Thus, stressing the collective benefits of vaccination could increase the effectiveness of health campaigns.

Fertility preservation (FP) aims to help individuals overcome the infertility associated with cancer treatments such as chemotherapy and radiation. The objective of this study was to assess the awareness, attitudes and knowledge of oncologists' and clinical practitioners' (CPs) about fertility preservation and its options in Lebanon. This was a cross-sectional study with surveys carried out between March 2012 and February 2013 on CPs at the American University of Beirut Medical Centre and Saint Jude's Children Cancer Centre as well as all registered oncologists in Lebanon. Ninety percent of CPs (n = 88) and 94% of oncologists (n = 53) agreed that fertility preservation should be discussed with patient before their cancer treatment. Our data showed a gender bias in relation to patients being informed of their FP options, as well as conflicting knowledge of FP options available in Lebanon among oncologists. The CPs were more likely to have accurate knowledge of FP options and treatment than oncologists. A proactive approach is required to: (1) increase the awareness and knowledge of FP; (2) improve attitudes towards FP; and (3) encourage its communication between CPs, oncologists and patients in Lebanon. Increased education programs, awareness campaigns and development of dedicated FP centres are needed.

2018-05-01

Despite being a primary response to child abuse, it is currently unknown whether contact with child protection services (CPS) does more good than harm. The aim of the current study was to examine whether contact with CPS is associated with improved mental health outcomes among adult respondents who reported experiencing child abuse, after adjusting for sociodemographic factors and abuse severity. The data were drawn from the 2012 Canadian Community Health Survey-Mental Health (CCHS-2012), which used a multistage stratified cluster design (household-level response rate = 79.8%). Included in this study were individuals aged 18 years and older living in the 10 Canadian provinces (N = 23,395). Child abuse included physical abuse, sexual abuse, and exposure to intimate partner violence (IPV). Mental health outcomes included lifetime mental disorders, lifetime and past year suicidal ideation, plans, and attempts, and current psychological well-being and functioning and distress. All models were adjusted for sociodemographic factors and severity of child abuse. For the majority of outcomes, there were no statistically significant differences between adults with a child abuse history who had CPS contact compared to those without CPS contact. However, those with CPS contact were more likely to report lifetime suicide attempts. These findings suggest that CPS contact is not associated with improved mental health outcomes. Implications are discussed. Copyright © 2018 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Socio-demographic inequalities in the prevalence, diagnosis and management of hypertension in India: analysis of nationally-representative survey data.

Hypertension is a major contributing factor to the current epidemic of cardiovascular disease in India. Small studies suggest high, and increasing, prevalence especially in urban areas, with poor detection and management, but national data has been lacking. The aim of the current study was to use nationally-representative survey data to examine socio-demographic inequalities in the prevalence, diagnosis and management of hypertension in Indian adults. Using data on self-reported diagnosis and treatment, and blood pressure measurement, collected from 12,198 respondents aged 18+ in the 2007 WHO Study on Global Ageing and Adult Health in India, factors associated with prevalence, diagnosis and treatment of hypertension were investigated. 22% men and 26% women had hypertension; prevalence increased steeply with body mass index (wealth. Adequate blood pressure control was sub-optimal in urban men. Hypertension is very common in India, even among underweight adults and those of lower socioeconomic position. Improved detection is needed to reduce the burden of disease attributable to hypertension. Levels of treatment and control are relatively good, particularly in women, although urban men require more careful attention.

Paid employment and common mental disorders in 50-64-year olds: analysis of three cross-sectional nationally representative survey samples in 1993, 2000 and 2007.

Associations between employment status and mental health are well recognised, but evidence is sparse on the relationship between paid employment and mental health in the years running up to statutory retirement ages using robust mental health measures. In addition, there has been no investigation into the stability over time in this relationship: an important consideration if survey findings are used to inform future policy. The aim of this study is to investigate the association between employment status and common mental disorder (CMD) in 50-64-year old residents in England and its stability over time, taking advantage of three national mental health surveys carried out over a 14-year period. Data were analysed from the British National Surveys of Psychiatric Morbidity of 1993, 2000 and 2007. Paid employment status was the primary exposure of interest and CMD the primary outcome - both ascertained identically in all three surveys (CMD from the revised Clinical Interview Schedule). Multivariable logistic regression models were used. The prevalence of CMD was higher in people not in paid employment across all survey years; however, this association was only present for non-employment related to poor health as an outcome and was not apparent in those citing other reasons for non-employment. Odds ratios for the association between non-employment due to ill health and CMD were 3.05 in 1993, 3.56 in 2000, and 2.80 in 2007, after adjustment for age, gender, marital status, education, social class, housing tenure, financial difficulties, smoking status, recent physical health consultation and activities of daily living impairment. The prevalence of CMD was higher in people not in paid employment for health reasons, but was not associated with non-employment for other reasons. Associations had been relatively stable in strength from 1993 to 2007 in those three cross-sectional nationally representative samples.

Full Text Available Psorosis is a damaging disease of citrus that is widespread in many parts of the world. Citrus psorosis virus (CPsV, the type species of the genus Ophiovirus, is the putative causal agent of psorosis. Detection of CPsV by laboratory methods, serology in particular is a primary requirement for large-scale surveys but their production has been impaired by the difficulty of obtaining sufficient clean antigen for immunization. Specific PAbs against coat protein were produced in E. coli using recombinant DNA approach. The full length CP gene fragment was amplified by RT-PCR using total RNA extracted from CPsV infected citrus leaves and CP specific primers. The obtained product (1320bp was cloned, sequenced and sub-cloned into pET-30(+ expression vector. Expression was induced and screened in different bacterial clones by the presence of the expressed protein (48kDa and optimized in one clone. Expressed CP was purified using batch chromatography under denaturing conditions. Specificity of expressed protein was demonstrated by ELISA before used as antigen for raising PAbs in mice. Specificity of the raised PAbs to CPsV was verified by ELISA and western blotting. The raised PAbs were showed highly effectiveness in screening by ELISA comparing with the commercial antibodies purchased from Agritest, Valanzano, Italy.The expression of CPsV CP gene in E. coli, production of PAbs using recombinant protein as an antigen, the suitability of these antibodies for use in immunodiagnostics against the CPsV Egyptian isolate have been accomplished in this work. Keywords: CPsV, CP, PAbs, RT-PCR, ELISA, Western blotting

Full Text Available Nonresponse is a common issue affecting the vast majority of surveys. Efforts to convince those unwilling to participate in a survey might not necessary result in a better picture of the target population and can lead to higher, not lower, nonresponse bias.We investigate the impact of non-response in the European Commission & European Central Bank Survey on the Access to Finance of Enterprises (SAFE, which collects evidence on the financing conditions faced by European SMEs compared with those of large firms. This survey, conducted by telephone bi-annually since 2009 by the ECB and the European Commission, provides a valuable means to search for this kind of bias, given the high heterogeneity of response propensities across countries.The study relies on so-called “Representativity Indicators” developed within the Representativity Indicators of Survey Quality (RISQ project, which measure the distance to a fully representative response. On this basis, we examine the quality of the SAFE Survey at different stages of the fieldwork as well as across different survey waves and countries. The RISQ methodology relies on rich sampling frame information, which is however partly limited in the case of the SAFE. We also assess the representativeness of the SAFE particular subsample created by linking the survey responses with the companies’ financial information from a business register; this sub-sampling is another potential source of bias which we also attempt to quantify. Finally, we suggest possible ways how to improve monitoring of the possible nonresponse bias in the future rounds of the survey.

2016-01-01

Full Text Available Background: The role of Papanicolaou (Pap test in cervical cancer screening need not be overemphasized. While most Western countries have adopted the liquid-based cytology (LBC, which is considered superior, many developing countries are still using the conventional Pap smear (CPS technique. Objective: To compare the staining and cytomorphological features on conventional versus liquid-based cervicovaginal smears. Materials and Methods: One hundred and forty cervicovaginal smears prepared by the standard conventional and LBC techniques were interpreted as per the Bethesda system of reporting cervicovaginal smears. Twelve parameters were studied, compared, and statistically analyzed. A P value <0.05 was considered to be statistically significant. Results: 129/140 (92% of CPSs and 130/140 (93% LBC smears were satisfactory. LBC had a significantly shorter screening time (2.0 ± 0.08 vs 4.0 ± 0.65 and better representative material than that of CPS (50% vs 42%. Neutrophils were significantly more in CPS than LBC (96% vs 92% with a P value <0.05 while hemorrhagic background and red blood cells (RBCs were more prominent in CPS. LBC showed significant artifactual changes in squamous epithelial cells. Epithelial abnormalities ranging from atypical squamous cells of undetermined significance (ASCUS to high grade squamous intraepithelial lesion (HSIL were seen in 3% (4 and 2% (2 of CPSs and LBCs, respectively. Organisms were better picked up in CPS (99% in CPS vs 73% LBC with a value of P = 0.0001. Conclusion: Although a shorter screening time and cleaner background are the major advantages of LBC, CPS is not inferior to LBC. Considering the high cost, rather than the advantages associated with LBC, we feel that CPS is a better option for developing countries.

Cooper, Alannah Louise; Brown, Janie

2017-12-18

Low response rates to surveys have been a long-standing issue in research. This includes research involving nurses and midwives. To gain representative samples, appropriate measures to maximise response rates need to be used. To explore ways to maximise response rates from nurses and midwives, using a hospital-wide survey as an example. All nurses and midwives at the study hospital were invited to participate in a survey. To encourage participation and elicit an adequate response rate, several strategies were used. A total of 1,000 surveys were distributed and 319 (32%) were returned. All the required age groups, levels of experience and types of nursing registration were represented in the responses and data saturation was achieved. It is important to pay attention to obtaining a representative sample. Further investigation of response rates to surveys by nurses and midwives is warranted. Strategies to maximise response rates from a target population should be used when conducting surveys. ©2017 RCN Publishing Company Ltd. All rights reserved.

Function generation and regulation libraries and their application to the control of the new main power converter (POPS) at the CERN CPS

International Nuclear Information System (INIS)

King, Q.; Page, S.T.; Thiesen, H.; Veenstra, M.

2012-01-01

Power converter control for the LHC is based on an embedded control computer called a Function Generator/Controller (FGC). Every converter includes an FGC with responsibility for the generation of the reference current as a function of time and the regulation of the circuit current, as well as control of the converter state. With many new converter controls software classes in development it was decided to generalize several key components of the FGC software in the form of C libraries: function generation in libfg, regulation, limits and simulation in libreg and DCCT, ADC and DAC calibration in libcal. These libraries were first used in the software class dedicated to controlling the new 60 MW main power converter (POPS) at the CERN Proton Synchrotron (CPS) where regulation of both magnetic field and circuit current is supported. This paper reports on the functionality provided by each library and in particular libfg and libreg. The libraries are already being used by software classes in development for the next generation FGC for Linac4 converters, as well as the CERN SPS converter controls (MUGEF) and MedAustron converter regulation board.

[Psychotherapy and Religion: A Representative Survey Among Psychotherapists in Southern Germany].

Science.gov (United States)

Marquardt, Michael; Demling, Joachim Heinrich

2016-12-01

Objective: Religion and spirituality play an appreciable role as a problem area or as a resource for patients with mental disorders. It is therefore of interest what attitudes psychotherapists assume towards this complex range of issues in their work, but also in their personal lives. The majority of empirical studies on this subject originate from the USA, with little data being available from Europe and Germany. Our own survey among practising psychotherapists was designed to elucidate these questions. Method and Study Population: A cross-sectional study was conducted in the form of a written survey of all accessible practising psychotherapists in the area of Northern Bavaria (Franconian administrative districts; n=1 081, return rate 65%). Results: Around two-thirds of the therapists consider religion to be an important subject in psychotherapy, but only one-fifth of them routinely take a history of the patients' religious beliefs. The therapists' own closeness to religion correlates positively with the tendency to incorporate religion in their therapy. In around one-third of the therapists, religion holds an important place within their own world view, although significantly fewer psychotherapists than the general population of Franconia are bound to a specific confession. Around one-quarter had at least once consulted a pastor due to a patient, while each seventh therapist had at least once actively mediated contact to a pastor. Conclusions: Religion is a subject that is relevant for therapeutic practice, but a history of religious beliefs is rarely taken on a routine basis. The incorporation of religion into psychotherapy correlates with religious characteristics of the therapists ("personal bias"). There appears to be a "religiosity gap" between psychotherapists and the general population. Advanced training on the subject of "religion/spirituality" and increased consideration in supervision may counteract the danger of religious needs and religion

No information regarding the management of manure from beef cattle feedlots is available for Brazil. To fill this knowledge gap, a survey of 73 feedlots was conducted in 7 Brazilian states. In this survey, questions were asked regarding animal characteristics, their diets, and manure handling management from generation to disposal. These feedlots finished 831,450 animals in 2010. The predominant breed fed was Nellore, with average feeding periods of 60 to 135 d. Corn was the primary source of grain used in the feedlot diets (76% of surveyed animals) with concentrate inclusion levels ranging from 81 to 90% (38% of surveyed animals). The most representative manure management practice was the removal of manure from pens only at the end of the feeding period. Subsequently, the manure was stored in mounds before being applied to crop and pasture lands. Runoff, mainly from rainwater, was collected in retention ponds and used for agriculture. However, the quantity of runoff was not known. Manure was composted for only 20% of the animals in the survey and was treated in anaerobic digesters for only 1% of the animals. Manure from 59% of the cattle surveyed was used as fertilizer, providing a cost savings over the use of synthetic fertilizers. Overall, chemical analysis of the manure before application to fields was conducted for the manure of 56% of the surveyed animals, but the exact quantity applied (per hectare) was unknown for 48%. Feedlots representing 48% of the surveyed animals noted similar or greater crop and pasture yields when using manure, rather than synthetic fertilizers. In addition, 32% mentioned an increase in soil organic matter. Feedlots representing 88% of the surveyed cattle indicated that information concerning management practices that improve manure use efficiency is lacking. Feedlots representing 93% of the animals in the survey reported having basic information regarding the generation of energy and fertilizer with anaerobic digesters. However

Income Inequality and Adolescent Gambling Severity: Findings from a Large-Scale Italian Representative Survey

Full Text Available Background: Studies have shown that problems related to adult gambling have a geographical and social gradient. For instance, adults experiencing gambling-related harms live in areas of greater deprivation; are unemployed, and have lower income. However, little is known about the impact of socioeconomic inequalities on adolescent problem gambling. The main purpose of the present study was to investigate the contextual influences of income inequality on at-risk or problem gambling (ARPG in a large-scale nationally representative sample of Italian adolescents. A secondary aim was to analyze the association between perceived social support (from family, peers, teachers, and classmates and ARPG.Methods: Data from the 2013–2014 Health Behavior in School-aged Children Survey (HBSC Study was used for cross-sectional analyses of ARPG. A total of 20,791 15-year-old students completed self-administered questionnaires. Region-level data on income inequality (GINI index and overall wealth (GDP per capita were retrieved from the National Institute of Statistics (Istat. The data were analyzed using the multi-level logistic regression analysis, with students at the first level and regions at the second level.Results: The study demonstrated a North–South gradient for the prevalence of ARPG, with higher prevalence of ARPG in the Southern/Islands/Central Regions (e.g., 11% in Sicily than in Northern Italy (e.g., 2% in Aosta Valley. Students in regions of high-income inequality were significantly more likely than those in regions of low-income inequality to be at-risk or problem gamblers (following adjustment for sex, family structure, family affluence, perceived social support, and regionale wealth. Additionally, perceived social support from parents and teachers were negatively related to ARPG.Conclusions: Income inequality may have a contextual influence on ARPG. More specifically, living in regions of highest income inequality appeared to be a potential

Jubeli, Y.; Al-Hilal, M.; Al-Ali, A.

1998-06-01

A combination of several exploration techniques was carried out at the main phosphatic outcrop of Ain Laylon in the Syrian coastal region. The survey was extended along an E-W profile parallel to Wadi Al-Mzeraa over a distance of about 23 km from Ain Laylon site towards the shoreline of the Mediterranean Sea. The techniques used in this survey included soil radon emanometry, gamma ray spectrometry and soil geochemistry, with the purpose of evaluating the effects of weathering and erosion on the uranium-hearing phosphate formations in the study ares. Soil radon concentration and gamma ray total count rates found to be ranging between 115-472 pCi/l and 52-520 cps over the main phosphate deposit of Ain Layton and between 16-241 pCi/l and 15-300 cps along the profile of Wadi Al-Mzeraa - Rwemiyeh respectively. Some suitable elements such as U, Zn, Pb, Cr, Fe and Sr were also analyzed to trace the dispersion pattern of uranium and its controls throughout the area. The results showed that the distribution of both radon emission and gamma ray activity, in accordance with chemical uranium and some associated trace elements, were almost identical over the study area. The anomalously high values in all cases were basically found to be related to the main phosphatic outcrop and to the reprecipitation processes at their vicinity following the alteration of the phosphates. The prevailing topographic conditions of the drainage system has probably played a crucial role in carrying the uraniferous solutions from its phosphatic source down to the nearby sedimentary environment. This appears to be sufficient enough to produce an anomalous halo resulting in the detection of some relatively high radon and gamma values of about 7 and 15 times the background respectively, especially close to the main phosphate outcrop. A notable gradual decrease was then observed at the following sampling sites along the pathway west of Ain Laylon site approaching the background level at a distance of

To determine opinions and attitudes of the German general population toward the treatment methods of reproductive medicine: egg donation, surrogate mothering, and reproductive cloning. Representative survey. German general population: face-to-face interviews at home with 2,110 persons, aged 18-50 years. Patients were not included. No interventions took place. Approval and disapproval of treatment methods of reproductive medicine and preimplantation genetic diagnosis were assessed by questionnaires regarding medical, age, reasons, or general. Overall, the diverse treatment methods of reproductive medicine found comparable rates of approval and disapproval. Legalization of egg donation was approved by a slight majority (50.8%), particularly for medical reasons (35.9%). Surrogate mothering found lower overall rates of approval (43.7%), 28.5% supported an admission for medical reasons. Reproductive cloning was rejected by the vast majority (82.9%). Attitudes to reproductive medicine were affected by age and the individual reproductive experiences. New techniques in reproductive medicine and their development provide hope and health promises for affected couples but also entail long-term risks and ethical issues. Balancing the individual's right to a reproductive autonomy and choice and ethical standards will constitute a future challenge for society. Results demonstrate considerable uncertainty and information deficits in the community.

Adverse childhood experiences among children placed in and adopted from foster care: Evidence from a nationally representative survey.

Science.gov (United States)

Turney, Kristin; Wildeman, Christopher

2017-02-01

Despite good reason to believe that children in foster care are disproportionately exposed to adverse childhood experiences (ACEs), relatively little research considers exposure to ACEs among this group of vulnerable children. In this article, we use data from the 2011-2012 National Survey of Children's Health (NSCH), a nationally representative sample of non-institutionalized children ages 0-17 in the United States, to estimate the association between foster care placement and exposure to an array of ACEs. In adjusted logistic regression models, we find that children placed in foster care or adopted from foster care, compared to their counterparts, were more likely to experience parental divorce or separation, parental death, parental incarceration, parental abuse, violence exposure, household member mental illness, and household member substance abuse. These children were also more likely to experience ACEs than children across different thresholds of socioeconomic disadvantage (e.g., children in households with incomes below the poverty line) and across different family structures (e.g., children in single-mother families). These results advance our understanding of how children in foster care, an already vulnerable population, are disproportionately exposed to ACEs. This exposure, given the link between ACEs and health, may have implications for children's health and wellbeing throughout the life course. Copyright © 2016 Elsevier Ltd. All rights reserved.

Community participation in peripheral public health facilities has in many countries focused on including community representatives in Health Facility Management Committees (HFMCs). In Kenya, HFMC roles are being expanded with the phased implementation of the Health Sector Services Fund (HSSF). Under HSSF, HFMCs manage facility funds which are dispersed directly from central level into facility bank accounts. We assessed how prepared HFMCs were to undertake this new role in advance of HSSF roll out, and considered the implications for Kenya and other similar settings. Data were collected through a nationally representative sample of 248 public health centres and dispensaries in 24 districts in 2010. Data collection included surveys with in-charges (n = 248), HFMC members (n = 464) and facility users (n = 698), and record reviews. These data were supplemented by semi-structured interviews with district health managers in each district. Some findings supported preparedness of HFMCs to take on their new roles. Most facilities had bank accounts and HFMCs which met regularly. HFMC members and in-charges generally reported positive relationships, and HFMC members expressed high levels of motivation and job satisfaction. Challenges included users' low awareness of HFMCs, lack of training and clarity in roles among HFMCs, and some indications of strained relations with in-charges. Such challenges are likely to be common to many similar settings, and are therefore important considerations for any health facility based initiatives involving HFMCs. Most HFMCs have the basic requirements to operate. However to manage their own budgets effectively and meet their allocated roles in HSSF implementation, greater emphasis is needed on financial management training, targeted supportive supervision, and greater community awareness and participation. Once new budget management roles are fully established, qualitative and quantitative research on how HFMCs are adapting to

Further assessment of survey results from the beaches around Sellafield

Contaminated material continues to be found on the beaches, estuaries and salt marshes. An initial apparent fall in the frequency of discovery of highly contaminated samples has not been sustained. In the last week of surveys reported here, a change was noted in the type of contaminated material found. Results averaged on the entire period from 19 November 1983 to 13 February 1984 suggest that about 2 items every kilometre might be found giving a reading in excess of 1 mR/L βγ and 1 item every few kilometres giving a reading in excess of 10 mR/h βγ, with actual contact dose rates possible of about a hundred times higher than apparent instrument readings. A member of the public could pick up an item contaminated in excess of the 10 mR/h βγ or 1000 cps criterion and hold it for sufficiently long to sustain an appreciable dose to the skin surface. These and laboratory studies of contaminated materials confirmed the Board's views that the only situations of concern are those of prolonged handling of debris and contamination of the skin, rather than intake by ingestion or inhalation.

2016-01-01

Streptococcus suis serotype 2 is an encapsulated bacterium and one of the most important bacterial pathogens in the porcine industry. Despite decades of research for an efficient vaccine, none is currently available. Based on the success achieved with other encapsulated pathogens, a glycoconjugate vaccine strategy was selected to elicit opsonizing anti-capsular polysaccharide (anti-CPS) IgG antibodies. In this work, glycoconjugate prototypes were prepared by coupling S. suis type 2 CPS to tetanus toxoid, and the immunological features of the postconjugation preparations were evaluated in vivo. In mice, experiments evaluating three different adjuvants showed that CpG oligodeoxyribonucleotide (ODN) induces very low levels of anti-CPS IgM antibodies, while the emulsifying adjuvants Stimune and TiterMax Gold both induced high levels of IgGs and IgM. Dose-response trials comparing free CPS with the conjugate vaccine showed that free CPS is nonimmunogenic independently of the dose used, while 25 μg of the conjugate preparation was optimal in inducing high levels of anti-CPS IgGs postboost. With an opsonophagocytosis assay using murine whole blood, sera from immunized mice showed functional activity. Finally, the conjugate vaccine showed immunogenicity and induced protection in a swine challenge model. When conjugated and administered with emulsifying adjuvants, S. suis type 2 CPS is able to induce potent IgM and isotype-switched IgGs in mice and pigs, yielding functional activity in vitro and protection against a lethal challenge in vivo, all features of a T cell-dependent response. This study represents a proof of concept for the potential of glycoconjugate vaccines in veterinary medicine applications against invasive bacterial infections. PMID:27113360

Sample representativeness verification of the FADN CZ farm business sample

Directory of Open Access Journals (Sweden)

Marie Prášilová

2011-01-01

Full Text Available Sample representativeness verification is one of the key stages of statistical work. After having joined the European Union the Czech Republic joined also the Farm Accountancy Data Network system of the Union. This is a sample of bodies and companies doing business in agriculture. Detailed production and economic data on the results of farming business are collected from that sample annually and results for the entire population of the country´s farms are then estimated and assessed. It is important hence, that the sample be representative. Representativeness is to be assessed as to the number of farms included in the survey and also as to the degree of accordance of the measures and indices as related to the population. The paper deals with the special statistical techniques and methods of the FADN CZ sample representativeness verification including the necessary sample size statement procedure. The Czech farm population data have been obtained from the Czech Statistical Office data bank.

Evidence suggests that adult per-capita alcohol consumption, as estimated from self-reports of nationally representative surveys, underestimates 'true' consumption, as measured as the sum of recorded and unrecorded consumption. The proportion of total adult alcohol per capita reported in representative surveys is usually labelled 'coverage'. The aim of the present paper was to estimate coverage for South Africa under different scenarios of alcohol use assessment and 'true' consumption. Five nationally representative surveys from South Africa were used to estimate the prevalence of drinking and the grams per day among current drinkers. All surveys used a complex multi-stage sampling frame that was accounted for by using survey weights. The total (recorded and unrecorded), the recorded and the adjusted total adult per-capita alcohol consumption in South Africa served as different estimates of the 'true' consumption. South Africa. Alcohol use information was assessed on a total of 8115, 16 398 and 13 181 adults (15 years or older) in surveys from the years 2003, 2005 and 2008, respectively. Two surveys in 2012 included 27 070 and 18 688 adults. Coverage of the alcohol use reported in the surveys was calculated, compared with the 'true' adult per-capita alcohol. The survey data covered between 11.8% [2005; 95% uncertainty interval (UI) = 9.3-16.2%)] and 19.4% (2003; 95% UI = 14.9-24.2%) of the total alcohol used per capita. The highest coverage of 27.9% (95% UI = 22.4-36.8%) was observed when looking only at recorded alcohol in 2003. Evidence from five nationally representative surveys assessing alcohol use suggests that less than 20% of the total adult per-capita alcohol consumption in South Africa is reported in surveys. © 2016 Society for the Study of Addiction.

To assess Australian adult physicians' views about evidence-based medicine (EBM) and quality improvement (QI). Cross-sectional postal survey of two hundred and forty-four randomly selected Australian physicians (78.5% response rate). Physicians' views about the promotion of EBM and QI and their impact on patient care, strategies to support better clinical practice and self-reported understanding of EBM terms. Sixty-eight per cent (95% confidence interval (CI): 62-74%) of physicians had a positive view of the current promotion of EBM in Australia. Significantly fewer (45%; 95% CI: 38-51%) were so positive about QI (P evidence, significantly fewer (21%; 95% CI: 17-27%) agreed they had sufficient time to do so (P Australian physicians have positive views of EBM, QI appears less well regarded. Initiatives to improve quality and safety that incorporate principles and language of EBM will likely be received better by physicians than isolated QI. Further enhancement of EBM requires concomitant attention to physician training, workplace infrastructure and supportive professional development.

The goal of this study was to obtain a representative estimate on concentration of natural radionuclides in private well water and the radiation exposure from drinking water of people living outside public water supply in Finland. According to earlier studies, the number of private well users in Finland is about 10% of the population. Nonetheless, this group receives more than half of the collective radiation dose due to natural radioactivity in drinking water. In a random sampling study 2,000 persons, not using a public water supply as their drinking water according to the Population Register Centre were selected to the survey. Among subjects who gave their consent, about 500 private well users were selected in the study. Activity concentration of radon ( 222 Rn), radium ( 226 Ra), uranium ( 238 U and 234 U), lead ( 210 Pb) and polonium ( 210 Po), and mass concentration of uranium were determined from 288 drilled wells and 184 wells dug in soil. The concentrations of natural radionuclides were several times higher in drilled wells than in wells dug in soil. The average radon concentration in drilled wells was 460 Bq/l and in dug wells 50 Bq/l. The highest concentrations were found in Southern Finland, in Uusimaa region, and in South-Western Finland. Additionally, occasional high concentrations were found all over Finland. The average uranium concentration in drilled wells was 21 μg/l and in dug wells 1 μg/l. Spatial distribution of uranium was essentially similar to that of radon. The average radium concentration in drilled wells was 0.05 Bq/l and in dug wells 0.02 Bq/l. Unlike radon and uranium, the highest radium concentrations were found in coastal area. The average lead concentration in drilled wells was 0.040 Bq/l and in dug wells 0.013 Bq/l and the average polonium concentration 0.048 Bq/l and 0.007 Bq/l, respectively. Spatial distributions of lead and polonium were similar to that of radon. The average annual effective dose from natural radionuclides for

The present study assesses the association between childhood exposure to parental violence and perpetration of marital violence as adults among a representative sample of 3,396 men in Bangladesh. We used secondary analysis of survey data from the nationally representative Bangladesh Demographic and Health Survey 2007 to examine factors associated with perpetration of martial violence among 3,396 ever-married men between the ages of 16 and 50 years. Outcome measure, marital violence perpetration, was measured using a modified Conflict Tactics Scale, and predictor variables included childhood exposure to parental violence, justification of marital violence, marital duration, religion, and demographic variables. Results indicate that marital violence perpetration is significantly associated with childhood exposure to marital violence, suggesting a cycle of violence that is maintained across generations. Implications for policy and practice are discussed. © The Author(s) 2015.

Directory and survey of particle physicists

1997-04-01

In order to develop a clearer understanding of the demographics of the U.S. particle physics workforce, the US Department of Energy, the National Science Foundation, and the Division of Particles and Fields of the American Physical Society commissioned a survey and census of particle physicists employed in the United States. This survey and census were conducted in 1995, with an update of the census in April 1997. The agencies and the scientific community were represented for the 1995 efforts by Dr. Robert Woods (DOE), Dr. William Chinowsky (NSF), and Prof. Uriel Nauenberg (DPF); for the current census, by Dr. Robert Diebold (DOE), Dr. Marvin Goldberg (NSF), and Dr. Patricia Rankin (NSF). The survey/census were carried out with the assistance of the Particle Data Group at Lawrence Berkeley National Laboratory. In order to obtain an accurate study of the current workforce and of future needs, we requested that all HEP physicists fill out and return the 1995 survey. There were 2494 respondents. For the 1997 census, a representative of each university and laboratory was asked to provide information on all persons at that institution who spend at least 50% of their research time on particle physics. In some cases this includes accelerator physicists. The total number of physicists in the 1997 census is 3492 from 155 institutions in the United States. The full survey questionnaires are shown. The primary one was addressed to individual particle physicists, while the secondary one was addressed to principal investigators and sought information about people leaving the field. There are many possible tables and plots from this survey, with a variety of correlations. Those chosen are representative of a cross-section of the demographic results. It should be emphasized that this survey was a snapshot in time, and does not have the same capabilities as would a series of surveys that are periodic in time. Care should be taken in interpreting the results of the tables and plots

Flaws in previous studies mean that findings of J-shaped risk curves for gambling should be disregarded. The current study aims to estimate the shape of risk curves for gambling losses and risk of gambling-related harm (a) for total gambling losses and (b) disaggregated by gambling activity. Four cross-sectional surveys. Nationally representative surveys of adults in Australia (1999), Canada (2000), Finland (2011) and Norway (2002). A total of 10 632 Australian adults, 3120 Canadian adults, 4484 people aged 15-74 years in Finland and 5235 people aged 15-74 years in Norway. Problem gambling risk was measured using the modified South Oaks Gambling Screen, the NORC DSM Screen for Gambling Problems and the Problem Gambling Severity Index. Risk curves for total gambling losses were estimated to be r-shaped in Australia {β losses = 4.7 [95% confidence interval (CI) = 3.8, 6.5], β losses(2 =)  -7.6 (95% CI = -17.5, -4.5)}, Canada [β losses = 2.0 (95% CI = 1.3, 3.9), β losses(2 =)  -3.9 (95% CI = -15.4, -2.2)] and Finland [β losses = 3.6 (95% CI = 2.5, 7.5), β losses(2 =)  -4.4 (95% CI = -34.9, -2.4)] and linear in Norway [β losses = 1.6 (95% CI = 0.6, 3.1), β losses(2 =)  -2.6 (95% CI = -12.6, 1.4)]. Risk curves for different gambling activities showed either linear, r-shaped or non-significant relationships. Player loss-risk curves for total gambling losses and for different gambling activities are likely to be linear or r-shaped. For total losses and electronic gaming machines, there is no evidence of a threshold below which increasing losses does not increase the risk of harm. © 2015 Society for the Study of Addiction.

Comparison of neighborhood-scale residential wood smoke emissions inventories using limited and intensive survey data

International Nuclear Information System (INIS)

Baxter, T.E.

1998-01-01

Emission inventory based estimations of pollutants resulting from residential combustion of wood are typically determined by collecting survey data that represent a single but relatively large area. While the pollutants in wood smoke emissions may represent a relatively low fraction (<10%) of an area's total annual emissions mass inventory, they can concentrate within the specific neighborhood areas where emitted. Thus, while the representativeness of a large-area survey approach is valid and useful, its application for estimating wood smoke pollutant levels within any particular neighborhood may be limited. The ability to obtain a better estimation of pollutant levels for evaluating potential health-related impacts within neighborhoods where wood smoke pollutants can concentrate requires survey data more representative of the particular area. This study compares residential wood combustion survey data collected from six residential neighborhoods in the metropolitan area of Flagstaff, Arizona. The primary purpose of this study is to determine the ability of data collected from a limited neighborhood-scale survey effort to represent that neighborhood's wood fuel consumption characteristics and wood smoke emissions. In addition, the variation that occurs between different neighborhoods regarding residential consumption of wood is also evaluated. Residential wood combustion survey data were collected compare wood burning device distribution, wood types and quantities burned, and emission rates. One neighborhood was surveyed once at approximately a 10% distribution rate and again at a 100% distribution rate providing data for evaluating the ability of a limited-effort survey to represent a more intensive survey. Survey methodology, results and recommendations are presented

Capsular Polysaccharide is a Main Component of Mycoplasma ovipneumoniae in the Pathogen-Induced Toll-Like Receptor-Mediated Inflammatory Responses in Sheep Airway Epithelial Cells

Full Text Available Mycoplasma ovipneumoniae (M. ovipneumoniae is characterized as an etiological agent of primary atypical pneumonia that specifically infects sheep and goat. In an attempt to better understand the pathogen-host interaction between the invading M. ovipneumoniae and airway epithelial cells, we investigated the host inflammatory responses against capsular polysaccharide (designated as CPS of M. ovipneumoniae using sheep bronchial epithelial cells cultured in an air-liquid interface (ALI model. Results showed that CPS derived from M. ovipneumoniae could activate toll-like receptor- (TLR- mediated inflammatory responses, along with an elevated expression of nuclear factor kappa B (NF-κB, activator protein-1 (AP-1, and interferon regulatory factor 3 (IRF3 as well as various inflammatory-associated mediators, representatively including proinflammatory cytokines, such as IL1β, TNFα, and IL8, and anti-inflammatory cytokines such as IL10 and TGFβ of TLR signaling cascade. Mechanistically, the CPS-induced inflammation was TLR initiated and was mediated by activations of both MyD88-dependent and MyD88-independent signaling pathways. Of importance, a blockage of CPS with specific antibody led a significant reduction of M. ovipneumoniae-induced inflammatory responses in sheep bronchial epithelial cells. These results suggested that CPS is a key virulent component of M. ovipneumoniae, which may play a crucial role in the inflammatory response induced by M. ovipneumoniae infections.

The 'maximum individual' concept based on US NRC Regulatory Guide 1.109 has been used for the public dose calculation in Korea. However, the 'maximum individual' results in largely overestimating the public dose. In Korea, the adoption of the 'representative person' is under consideration. The 'representative person' was recommended by ICRP Publication No. 101. In this study, individual habits (consumption of foodstuffs, use of local resources) of representative person have been analyzed or investigated. The age-specific food consumption rates of the representative person were derived from the Korean national dietary survey by government in 2005. The foodstuffs are classified into 12 classes - grain, fruits, kimchi, vegetables, milk, beef, pork, poultry, fishes, mollusca, crustacea, and seaweeds. The use of local resources such as the self-sufficiency of foodstuffs was investigated by using the questionnaire survey to the public members within 2 km from four nuclear power plant sites in Korea. The 95th percentile values are used for the top-two pathways such as grain and kimchi, but the average values are used for other foods. The results show that the effective dose from new habit data is about 30% lower than that from the existing data. (author)

Investigating why and for whom management ethnic representativeness influences interpersonal mistreatment in the workplace.

Lindsey, Alex P; Avery, Derek R; Dawson, Jeremy F; King, Eden B

2017-11-01

Preliminary research suggests that employees use the demographic makeup of their organization to make sense of diversity-related incidents at work. The authors build on this work by examining the impact of management ethnic representativeness-the degree to which the ethnic composition of managers in an organization mirrors or is misaligned with the ethnic composition of employees in that organization. To do so, they integrate signaling theory and a sense-making perspective into a relational demography framework to investigate why and for whom management ethnic representativeness may have an impact on interpersonal mistreatment at work. Specifically, in three complementary studies, the authors examine the relationship between management ethnic representativeness and interpersonal mistreatment. First, they analyze the relationship between management ethnic representativeness and perceptions of harassment, bullying, and abuse the next year, as moderated by individuals' ethnic similarity to others in their organizations in a sample of 60,602 employees of Britain's National Health Service. Second, a constructive replication investigates perceived behavioral integrity as an explanatory mechanism that can account for the effects of representativeness using data from a nationally representative survey of working adults in the United States. Third and finally, online survey data collected at two time points replicated these patterns and further integrated the effects of representativeness and dissimilarity when they are measured using both objective and subjective strategies. Results support the authors' proposed moderated mediation model in which management ethnic representation is negatively related to interpersonal mistreatment through the mediator of perceived behavioral integrity, with effects being stronger for ethnically dissimilar employees.

Full Text Available Sugar-containing beverages are often seen as a negative influence on diet quality and body weight control. The present study examines the consumption of 100% fruit juice (FJ based on a seven-day dietary survey in a representative sample of French adults (n = 1607. About a half of the participants (44% consumed FJ, most often at breakfast time (60%. Average intake in FJ consumers was 115.6 ± 4.0 mL/day (46.3 ± 1.7 kcal/day. Prevalence of consumption increased with education and income and decreased with age, but no association was observed with body mass index (BMI, physical activity, or smoking. In consumers, FJ brought 2% daily energy and contributed larger proportions of vitamins (B1 7%, B2 3%, B5 5%, B6 6%, B9 10%, C 32%, E 9%, beta-carotene 5%, minerals (magnesium 4%, potassium 7%, and free sugars (19%. FJ consumers ingested more whole fruits, vegetables, and many other foods than non-consumers did. Free sugars represented 11.2% of the daily energy in FJ consumers versus 8.6% in non-consumers. This cross-sectional survey reveals that FJ contributes to diet quality without association with excess body weight. These observations should be confirmed in longitudinal studies. They support the view that contribution to diet quality should be specifically recognized in the context of the World Health Organization (WHO recommended decrease of free sugar intake.

Tritrichomonas foetus (T. foetus) is a flagellated protozoan parasite that is recognized as a significant cause of diarrhea in domestic cats with a prevalence rate as high as 30%. No drugs have been shown to consistently eliminate T. foetus infection in all cats. Cysteine proteases (CPs) have been identified as mediators of T. foetus-induced adhesion-dependent cytotoxicity to the intestinal epithelium. These CPs represent novel targets for the treatment of feline trichomonosis. However, cats also produce CPs that are part of life-critical systems. Thus, parasitic CPs need to be selectively targeted to reduce the potential for host toxicity. Previous studies have demonstrated the importance of a specific CP, CP30, in mediating bovine and human trichomonad cytopathogenicity. This CP has also recently been identified in feline T. foetus, although the function of this protease in the feline genotype remains unknown. Furthermore, the study objectives were to characterize the presence of CP30 in feline T. foetus isolates and to evaluate the effect of targeted inhibition of CP30 on feline T. foetus-induced adhesion dependent cytotoxicity.

Criminal investigations in child protective services cases: an empirical analysis.

Cross, Theodore P; Chuang, Emmeline; Helton, Jesse J; Lux, Emily A

2015-05-01

This study analyzed the frequency and correlates of criminal investigation of child maltreatment in cases investigated by child protective service (CPS), using national probability data from the National Survey of Child and Adolescent Well-Being. Criminal investigations were conducted in slightly more than 25% of cases. Communities varied substantially in percentage criminally investigated. Sexual abuse was the most frequent type of maltreatment criminally investigated followed by physical abuse. Logistic regression results indicated that criminal investigations were more likely when caseworkers perceived greater harm and more evidence; when CPS conducted an investigation rather than an assessment; when a parent or a legal guardian reported the maltreatment; and when cases were located in communities in which CPS and police had a memorandum of understanding (MOU) governing coordination. Most variation between communities in criminal investigation remained unexplained. The findings suggest the potential of MOUs for communities wanting to increase criminal investigation. © The Author(s) 2014.

In 1991 a wood fuel survey of 450 randomly selected households, representing 1% of the total number of households in Prince Edward Island, was conducted. The survey indicated that 49.8% of the households burned wood, up from 42.1% of households in the 1988-1989 survey. The wood burning households consumed an average of 4.92 cords of wood, consistent with the 4.90 cords in the 1989 survey. The total residential wood consumption was estimated at ca 100,377 cords, an increase from the 89,000 cords used in 1988-89. Wood cutters represented 23.4% of respondents, with buyers representing 25.4% of respondents. The wood burning appliances used by the respondents were: airtight wood stove 39.9%, wood furnace 22.5%, kitchen wood stove 15.7%, combined wood/oil furnace 8.9%, Franklin/non-airtight 4.4%, Kemac unit 4.4%, fireplace insert 3.1%, and open fireplace 1%. The most frequent response among rural wood users cited price as an advantage of wood fuel, while the most frequent response of urban users cited the quality of the heat. 9 figs., 47 tabs

There have been obstacles for internal migrants in China in accessing local public health services for some time. This study aimed to estimate the utilization of local public health services and its determinants among internal migrants. Data were from the 2014 and 2015 nationally representative cross-sectional survey of internal migrants in China. Multivariate logistic regressions were used to estimate the relationship between socioeconomic, migration, and demographic characteristics and public health services utilization. Our results showed that internal migrants in more developed eastern regions used less public health services. Those with higher socioeconomic status were more likely to use public health services. The years of living in the city of residence were positively associated with the utilization of public health services. Compared to migration within the city, migration across provinces significantly reduced the probability of using health records (OR = 0.88, 95% CI: 0.86-0.90), health education (OR = 0.97, 95% CI: 0.94-1.00), and health education on non-communicable diseases (OR = 0.92, 95% CI: 0.89-0.95) or through the Internet (OR = 0.96, 95% CI: 0.94-0.99). This study concludes that public health services coverage for internal migrants has seen great improvement due to government subsidies. Internal migrants with lower socioeconomic status and across provinces need to be targeted. More attention should be given to the local government in the developed eastern regions in order to narrow the regional gaps.

To examine the association of the Supplemental Nutrition Assistance Program (SNAP) and diet quality among low-income adults. We examined US nationally representative data from the National Health and Nutrition Examination Surveys 2003-2004, 2005-2006, 2007-2008, and 2009-2010. The data were analyzed from October 7, 2013, to March 1, 2014. The analytic sample consisted of 4211 low-income adults aged 20 to 64 years, of whom 1830 participate in SNAP. We adhered to the National Cancer Institute method in calculating the Healthy Eating Index 2010 and other dietary indicators, such as empty calorie intake. Bivariate and multivariable regression was used to compare SNAP participants and income-eligible nonparticipants among the full sample and subsamples of age, sex, race/ethnicity, and food insecurity. Compared with low-income nonparticipants, adjusted analyses reveal that SNAP participants had lower dietary quality scores overall (42.58 vs 44.36, P≤.0001) and lower scores for fruits and vegetables, seafood and plant proteins (1.55 vs 1.77, P≤.0022), and empty calories (9.03 vs 9.90, P≤.0001), but they exhibited comparable scores on whole grain, refined grain, total dairy, total protein, fatty acid, and sodium intakes. The association between SNAP participation and lower dietary quality was statistically significant among women, Hispanics, young adults, and individuals who were food secure. Our analyses suggest that SNAP participants have lower dietary quality than their income-eligible nonparticipant counterparts. Although SNAP has an important role in providing nutrition assistance to eligible low-income individuals, interventions are warranted to improve the dietary quality of participants.

Using Linked Survey Paradata to Improve Sampling Strategies in the Medical Expenditure Panel Survey

Directory of Open Access Journals (Sweden)

Mirel Lisa B.

2017-06-01

Full Text Available Using paradata from a prior survey that is linked to a new survey can help a survey organization develop more effective sampling strategies. One example of this type of linkage or subsampling is between the National Health Interview Survey (NHIS and the Medical Expenditure Panel Survey (MEPS. MEPS is a nationally representative sample of the U.S. civilian, noninstitutionalized population based on a complex multi-stage sample design. Each year a new sample is drawn as a subsample of households from the prior year’s NHIS. The main objective of this article is to examine how paradata from a prior survey can be used in developing a sampling scheme in a subsequent survey. A framework for optimal allocation of the sample in substrata formed for this purpose is presented and evaluated for the relative effectiveness of alternative substratification schemes. The framework is applied, using real MEPS data, to illustrate how utilizing paradata from the linked survey offers the possibility of making improvements to the sampling scheme for the subsequent survey. The improvements aim to reduce the data collection costs while maintaining or increasing effective responding sample sizes and response rates for a harder to reach population.

Malaria is endemic throughout Malawi, but little is known about quality of malaria case management at publicly-funded health facilities, which are the major source of care for febrile patients. In April-May 2011, we conducted a nationwide, geographically-stratified health facility survey to assess the quality of outpatient malaria diagnosis and treatment. We enrolled patients presenting for care and conducted exit interviews and re-examinations, including reference blood smears. Moreover, we assessed health worker readiness (e.g., training, supervision) and health facility capacity (e.g. availability of diagnostics and antimalarials) to provide malaria case management. All analyses accounted for clustering and unequal selection probabilities. We also used survey weights to produce estimates of national caseloads. At the 107 facilities surveyed, most of the 136 health workers interviewed (83%) had received training on malaria case management. However, only 24% of facilities had functional microscopy, 15% lacked a thermometer, and 19% did not have the first-line artemisinin-based combination therapy (ACT), artemether-lumefantrine, in stock. Of 2,019 participating patients, 34% had clinical malaria (measured fever or self-reported history of fever plus a positive reference blood smear). Only 67% (95% confidence interval (CI): 59%, 76%) of patients with malaria were correctly prescribed an ACT, primarily due to missed malaria diagnosis. Among patients without clinical malaria, 31% (95% CI: 24%, 39%) were prescribed an ACT. By our estimates, 1.5 million of the 4.4 million malaria patients seen in public facilities annually did not receive correct treatment, and 2.7 million patients without clinical malaria were inappropriately given an ACT. Malawi has a high burden of uncomplicated malaria but nearly one-third of all patients receive incorrect malaria treatment, including under- and over-treatment. To improve malaria case management, facilities must at minimum have

High Assurance Control of Cyber-Physical Systems with Application to Unmanned Aircraft Systems

Science.gov (United States)

Kwon, Cheolhyeon

With recent progress in the networked embedded control technology, cyber attacks have become one of the major threats to Cyber-Physical Systems (CPSs) due to their close integration of physical processes, computational resources, and communication capabilities. While CPSs have various applications in both military and civilian uses, their on-board automation and communication afford significant advantages over a system without such abilities, but these benefits come at the cost of possible vulnerability to cyber attacks. Traditionally, most cyber security studies in CPSs are mainly based on the computer security perspective, focusing on issues such as the trustworthiness of data flow, without rigorously considering the system's physical processes such as real-time dynamic behaviors. While computer security components are key elements in the hardware/software layer, these methods alone are not sufficient for diagnosing the healthiness of the CPSs' physical behavior. In seeking to address this problem, this research work proposes a control theoretic perspective approach which can accurately represent the interactions between the physical behavior and the logical behavior (computing resources) of the CPS. Then a controls domain aspect is explored extending beyond just the logical process of the CPS to include the underlying physical behavior. This approach will allow the CPS whose physical operations are robust/resilient to the damage caused by cyber attacks, successfully complementing the existing CPS security architecture. It is important to note that traditional fault-tolerant/robust control methods could not be directly applicable to achieve resiliency against malicious cyber attacks which can be designed sophisticatedly to spoof the security/safety monitoring system (note this is different from common faults). Thus, security issues at this layer require different risk management to detect cyber attacks and mitigate their impact within the context of a unified

Who and where are the uncounted children? Inequalities in birth certificate coverage among children under five years in 94 countries using nationally representative household surveys.

Science.gov (United States)

Bhatia, Amiya; Ferreira, Leonardo Zanini; Barros, Aluísio J D; Victora, Cesar Gomes

Birth registration, and the possession of a birth certificate as proof of registration, has long been recognized as a fundamental human right. Data from a functioning civil registration and vital statistics (CRVS) system allows governments to benefit from accurate and universal data on birth and death rates. However, access to birth certificates remains challenging and unequal in many low and middle-income countries. This paper examines wealth, urban/rural and gender inequalities in birth certificate coverage. We analyzed nationally representative household surveys from 94 countries between 2000 and 2014 using Demographic Health Surveys and Multiple Indicator Cluster Surveys. Birth certificate coverage among children under five was examined at the national and regional level. Absolute measures of inequality were used to measure inequalities in birth certificate coverage by wealth quintile, urban/rural residence and sex of the child. Over four million children were included in the analysis. Birth certificate coverage was over 90% in 29 countries and below 50% in 36 countries, indicating that more than half the children under five surveyed in these countries did not have a birth certificate. Eastern & Southern Africa had the lowest average birth certificate coverage (26.9%) with important variability among countries. Significant wealth inequalities in birth certificate coverage were observed in 74 countries and in most UNICEF regions, and urban/rural inequalities were present in 60 countries. Differences in birth certificate coverage between girls and boys tended to be small. We show that wealth and urban/rural inequalities in birth certificate coverage persist in most low and middle income countries, including countries where national birth certificate coverage is between 60 and 80%. Weak CRVS systems, particularly in South Asia and Africa lead rural and poor children to be systematically excluded from the benefits tied to a birth certificate, and prevent these

Recently it has become an important subject to reduce exposure to radiation from radioactive corrosion products (CPs) during maintenance and repair works in reactor plants. Metallic sodium is used as cooling material in fast reactor plants, leading to different CP behaviours compared to light water reactors. In the present study, a computer code for analyzing behaviours of CPs in fast reactor plants is developed. The analysis code, called PSYCHE, makes it possible to perform consistent analysis of production, migration and deposition of CPs in primary circuits together with dose rate around piping of apparatus in cooling systems. An analysis model is developed based on test results on CP behaviour in out-pile sodium. The model, called the ''dissolution-deposition model'', can reproduce atom-selective behaviour, transient phenomenon and downstream effect of CPs, which represent mass transfer phenomena in sodium. Verification of this code is carried out on the basis of CP measurements made in ''Joyo''. The calculation vs. measurement ratio is found to be 0.5 - 2 for CP deposition density in piping for cooling systems and 0.7 - 1.3 for dose rate, demonstrating that this code can give reasonable results. Analysis is also made to predict future changes in total amount of deposited CP in ''Joyo''. (Nogami, K.)

Dementia and representative democracy: Exploring challenges and implications for democratic citizenship.

Science.gov (United States)

Sonnicksen, Jared

2016-05-01

Despite growing recognition of the rights of people with dementia for full citizenship, issues related to democracy, whether from theoretical or practical perspectives, remain neglected. Especially since discourses on dementia have expanded to this rights-based approach, it is imperative to begin to examine the meanings and practices of democracy within a context of dementia. Accordingly, the purpose of this article is to assess implications of dementia in the context of democracy. Rather than surveying the variety of democratic concepts, it will focus the analytical framework on representative democracy and then outline several challenges to and for representative democracy and citizens with dementia. The intention is to begin to identify paths for ensuring representation, inclusion and participation for those who have dementia. © The Author(s) 2016.

Impact of 4 Lactobacillus plantarum capsular polysaccharide clusters on surface glycan composition and host cell signaling

Directory of Open Access Journals (Sweden)

Remus Daniela M

2012-11-01

Full Text Available Abstract Background Bacterial cell surface-associated polysaccharides are involved in the interactions of bacteria with their environment and play an important role in the communication between pathogenic bacteria and their host organisms. Cell surface polysaccharides of probiotic species are far less well described. Therefore, improved knowledge on these molecules is potentially of great importance to understand the strain-specific and proposed beneficial modes of probiotic action. Results The Lactobacillus plantarum WCFS1 genome encodes 4 clusters of genes that are associated with surface polysaccharide production. Two of these clusters appear to encode all functions required for capsular polysaccharide formation (cps2A-J and cps4A-J, while the remaining clusters are predicted to lack genes encoding chain-length control functions and a priming glycosyl-transferase (cps1A-I and cps3A-J. We constructed L. plantarum WCFS1 gene deletion mutants that lack individual (Δcps1A-I, Δcps2A-J, Δcps3A-J and Δcps4A-J or combinations of cps clusters (Δcps1A-3J and Δcps1A-3I, Δcps4A-J and assessed the genome wide impact of these mutations by transcriptome analysis. The cps cluster deletions influenced the expression of variable gene sets in the individual cps cluster mutants, but also considerable numbers of up- and down-regulated genes were shared between mutants in cps cluster 1 and 2, as well as between mutant in cps clusters 3 and 4. Additionally, the composition of overall cell surface polysaccharide fractions was altered in each mutant strain, implying that despite the apparent incompleteness of cps1A-I and cps3A-J, all clusters are active and functional in L. plantarum. The Δcps1A-I strain produced surface polysaccharides in equal amounts as compared to the wild-type strain, while the polysaccharides were characterized by a reduced molar mass and the lack of rhamnose. The mutants that lacked functional copies of cps2A-J, cps3A-J or cps4A

Recent studies suggest a possible link between post-traumatic stress disorder (PTSD) and obesity risk, which would have implications for the development of obesity-related diseases in this population. The present study examined the association between PTSD and obesity and whether this association differed by sex in a representative sample of the US population. A secondary objective was to determine whether the association between PTSD and obesity was mediated by binge eating disorder (BED). Data were from the Collaborative Psychiatric Epidemiology Surveys (CPES), which comprises three nationally representative cross-sectional surveys that were conducted between 2001 and 2003. Logistic regression analyses weighted to represent the general US adult population were performed. In the total sample of 20,013 participants, rates of obesity were 24.1% for persons without a lifetime history of PTSD and 32.6% among persons with PTSD in the past year. Adjusting for socio-demographic characteristics, depression, substance and alcohol abuse/dependence, and psychotropic medication status, past year PTSD was associated with greater likelihood of obesity (odds ratio (OR) = 1.51; 95% confidence interval (CI) = 1.18, 1.95), with no differences by gender. BED did not statistically mediate the relationship between PTSD and obesity. The present study provides support for a link between PTSD and obesity. Findings further existing literature by indicating that the association is consistent across sexes and is not statistically mediated by BED.

1995-01-01

ARIES (Autonomous Robotic Inspection Experimental System) is under development for the Department of Energy (DOE) to survey and inspect drums containing low-level radioactive waste stored in warehouses at DOE facilities. This paper focuses on the mechanical deployment system-referred to as the camera positioning system (CPS)-used in the project. The CPS is used for positioning four identical but separate camera packages consisting of vision cameras and other required sensors such as bar-code readers and light stripe projectors. The CPS is attached to the top of a mobile robot and consists of two mechanisms. The first is a lift mechanism composed of 5 interlocking rail-elements which starts from a retracted position and extends upward to simultaneously position 3 separate camera packages to inspect the top three drums of a column of four drums. The second is a parallelogram special case Grashof four-bar mechanism which is used for positioning a camera package on drums on the floor. Both mechanisms are the subject of this paper, where the lift mechanism is discussed in detail

Assessing the value of the NHIS for studying changes in state coverage policies: the case of New York.

Science.gov (United States)

Long, Sharon K; Graves, John A; Zuckerman, Stephen

2007-12-01

(1) To assess the effects of New York's Health Care Reform Act of 2000 on the insurance coverage of eligible adults and (2) to explore the feasibility of using the National Health Interview Survey (NHIS) as opposed to the Current Population Survey (CPS) to conduct evaluations of state health reform initiatives. We take advantage of the natural experiment that occurred in New York to compare health insurance coverage for adults before and after the state implemented its coverage initiative using a difference-in-differences framework. We estimate the effects of New York's initiative on insurance coverage using the NHIS, comparing the results to estimates based on the CPS, the most widely used data source for studies of state coverage policy changes. Although the sample sizes are smaller in the NHIS, the NHIS addresses a key limitation of the CPS for such evaluations by providing a better measure of health insurance status. Given the complexity of the timing of the expansion efforts in New York (which encompassed the September 11, 2001 terrorist attacks), we allow for difference in the effects of the state's policy changes over time. In particular, we allow for differences between the period of Disaster Relief Medicaid (DRM), which was a temporary program implemented immediately after September 11th, and the original components of the state's reform efforts-Family Health Plus (FHP), an expansion of direct Medicaid coverage, and Healthy New York (HNY), an effort to make private coverage more affordable. 2000-2004 CPS; 1999-2004 NHIS. We find evidence of a significant reduction in uninsurance for parents in New York, particularly in the period following DRM. For childless adults, for whom the coverage expansion was more circumscribed, the program effects are less promising, as we find no evidence of a significant decline in uninsurance. The success of New York at reducing uninsurance for parents through expansions of both public and private coverage offers hope for new

Attitudes Toward Intimate Partner Violence and Associations With Condom Use Among Men in Haiti: An Analysis of the Nationally Representative Demographic Health Survey.

Science.gov (United States)

Conserve, Donaldson F; Whembolua, Guy-Lucien S; Surkan, Pamela J

2016-03-01

Although men have substantial decision-making power regarding condom use, the majority of HIV knowledge and prevention studies in the general Haitian population have been conducted among youth and women. We investigated attitudes toward intimate partner violence, knowledge of, and use of condoms among 9493 men in Haiti using data from the 2012 nationally representative Demographic and Health Survey. Only 36% of HIV-negative and 44% of HIV-positive men reported using a condom the last time they had had sex. Logistic regression revealed that believing it was justified for a man to hit or beat his wife if she refuses to have sex with him was associated with a lower odds of condom use. The odds of using a condom during last sex was higher among men who reported knowing condoms can prevent HIV and who had been tested for HIV. Given the low rate of condom use among men in Haiti, these findings suggest that interventions promoting HIV knowledge, HIV testing, and gender-violence prevention among men may also increase condom use. © The Author(s) 2014.

Aim: The aim of this study was to evaluate the perceptions of general practitioners (GPs) and community pharmacists (CPs) in Penang, Malaysia, towards consumer reporting of Adverse Drug Reactions (ADRs). Methodology: A cross-sectional mail survey was adopted for the performance of the study. Survey questionnaires were sent to 192 CPs and 400 GPs in the state of Penang, Malaysia. Reminders were sent to all the non-respondents after 3 weeks of the initial mailing. Data which were collected from the questionnaires were analyzed by using the Statistical Package for Social Science (SPSS), version 15. The Chi-square test was used to determine as to whether there was any significant difference between expected and observed frequencies at the alpha level of 0.05. Results: Only 104 respondents (47 CPs and 57 GPs) returned the survey, with a response rate of 18.0%- a figure which could be considered to be low. This study indicated that GPs and CPs were aware about the importance and benefits of consumer reporting. A majority of them (88.0%) thought that consumer reporting would add more benefits to the existing pharmacovigilance program. Similarly, 97% of the respondents agreed that reporting of ADRs was necessary and 87.0% respondents had seen ADRs among their patients. However, 57 of them (6.0%), had not been aware that the national program in Malaysia allowed consumers to report ADRs. A majority of them (97.0%) agreed that consumers needed more education regarding ADR reporting. Most of them (84.0%) thought that consumers could not write valid reports which were similar to reports which were made by healthcare professionals (HCPs). A majority of the respondents (68.0%) had not heard about the consumer reporting program in Malaysia and half of them did not believe that consumer reporting could overcome under-reporting, which was the main problem of the national pharmacovigilance program in Malaysia. Conclusion: The GPs and CPs were aware about the importance and benefits

The responsibility for safely managing the Tank Farms at Hanford belongs to Lockheed Martin Hanford Corporation which is part of the six company Project Hanford Management Team led by Fluor Daniel Hanford, Inc.. These Tank Farm Facilities contain numerous outdoor contamination areas which are surveyed at a periodicity consistent with the potential radiological conditions, occupancy, and risk of changes in radiological conditions. This document describes the survey documentation and data tracking method devised to track the results of contamination surveys this process is referred to as indexing. The indexing process takes a representative data set as an indicator for the contamination status of the facility. The data are further manipulated into a single value that can be tracked and trended using standard statistical methodology. To report meaningful data, the routine contamination surveys must be performed in a manner that allows the survey method and the data collection process to be recreated. Three key criteria are necessary to accomplish this goal: Accurate maps, consistent documentation, and consistent consolidation of data meeting these criteria provides data of sufficient quality to be tracked. Tracking of survey data is accomplished by converting the individual survey results into a weighted value, corrected for the actual number of survey points. This information can be compared over time using standard statistical analysis to identify trends. At the Tank Farms, the need to track and trend the facility's radiological status presents unique challenges. Many of these Tank Farm facilities date back to the second world war. The Tank Farm Facilities are exposed to weather extremes, plant and animal intrusion, as well as all of the normal challenges associated with handling radiological waste streams. Routine radiological surveys did not provide a radiological status adequate for continuing comparisons

Although spirometry is the gold-standard diagnostic test for obstructive airways diseases, it remains poorly utilised in clinical practice. We aimed to investigate the use of spirometry across India, the change in its usage over a period of time and to understand the reasons for its under-utilisation. Two nationwide surveys were conducted in the years 2005 and 2013, among four groups of doctors: chest physicians (CPs), general physicians (GenPs), general practitioners (GPs) and paediatricians (Ps). A total of 1,000 physicians from each of the four groups were randomly selected from our database in the years 2005 and 2013. These surveys were conducted in 52 cities and towns across 15 states in India. A questionnaire was administered to the physicians, which captured information about their demographic details, type of practice and use of spirometry. The overall response rates of the physicians in 2005 and 2013 were 42.8% and 54.9%, respectively. Spirometry was reported to be used by 55% CPs, 20% GenPs, 10% GPs and 5% Ps in 2005, and this increased by 30.9% among CPs (P value spirometry varied between 2005 and 2013. In all, 32.2% of physicians were unaware of which predicted equation they were using. The use of spirometry in India is low, although it seems to have improved over the years. The reasons identified in this study for under-utilisation should be used to address initiatives to improve the use of spirometry in clinical practice.

Subjective measures of household resilience to climate variability and change: insights from a nationally representative survey of Tanzania

Directory of Open Access Journals (Sweden)

Full Text Available Promoting household resilience to climate extremes has emerged as a key development priority. Yet tracking and evaluating resilience at this level remains a critical challenge. Most quantitative approaches rely on objective indicators and assessment frameworks, but these are not fully satisfactory. Much of the difficulty arises from a combination of conceptual ambiguities, challenges in selecting appropriate indicators, and in measuring the many intangible aspects that contribute to household resilience. More recently, subjective measures of resilience have been advocated in helping to overcome some of the limitations of traditional objective characterizations. However, few large-scale studies of quantitative subjective approaches to resilience measurement have been conducted. In this study, we address this gap by exploring perceived levels of household resilience to climate extremes in Tanzania and the utility of standardized subjective methods for its assessment. A nationally representative cross-sectional survey involving 1294 individuals was carried out by mobile phone in June 2015 among randomly selected adult respondents aged 18 and above. Factors that are most associated with resilience-related capacities are having had advance knowledge of a previous flood, and to a lesser extent, believing flooding to be a serious community problem. Somewhat surprisingly, though a small number of weak relationships are apparent, most socio-demographic variables do not exhibit statistically significant differences with regards to perceived resilience-related capacities. These findings may challenge traditional assumptions about what factors characterize household resilience, offering a motivation for studying both subjective and objective perspectives, and understanding better their relationship to one another. If further validated, subjective measures may offer potential as both a complement and alternative to traditional objective methods of resilience

A largely unaddressed issue in lower income countries and the Philippines, in particular, is the role of alcohol marketing and its potential link to early alcohol use among youth. This study examines the associations between exposures to alcohol marketing and Filipino youths' drinking prevalence and drunkenness. Cross-sectional analyses were used to examine the Global School-based Student Health Survey (GSHS) conducted in Philippines (2011). The self-administered questionnaires were completed by students primarily 13 to 16 years of age (N = 5,290). Three statistical models were computed to test the associations between alcohol marketing and alcohol use, while controlling for possible confounding factors. Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR: 1.84; 95% CI=1.06-3.21) among youths after controlling for demographic and psychosocial characteristics, peer environment, and risky behaviors. In addition, seeing alcohol ads in newspapers and magazines (AOR: 1.65, 95% CI=1.05-2.58) and seeing ads at sports events, concerts or fairs (AOR: 1.50, 95% CI =1.06-2.12) were significantly associated with increased reports of drunkenness. There are significant associations between alcohol marketing exposure and increased alcohol use and drunkenness among youth in the Philippines. These findings highlight the need to put policies into effect that restrict alcohol marketing practices as an important prevention strategy for reducing alcohol use and its dire consequences among vulnerable youth.

Public health practitioners, policy makers, and researchers alike have called for more data on individual worker's perceptions about workplace environment, job satisfaction, and training needs for a quarter of a century. The Public Health Workforce Interests and Needs Survey (PH WINS) was created to answer that call. Characterize key components of the public health workforce, including demographics, workplace environment, perceptions about national trends, and perceived training needs. A nationally representative survey of central office employees at state health agencies (SHAs) was conducted in 2014. Approximately 25,000 e-mail invitations to a Web-based survey were sent out to public health staff in 37 states, based on a stratified sampling approach. Balanced repeated replication weights were used to account for the complex sampling design. A total of 10,246 permanently employed SHA central office employees participated in PH WINS (46% response rate). Perceptions about training needs; workplace environment and job satisfaction; national initiatives and trends; and demographics. Although the majority of staff said they were somewhat or very satisfied with their job (79%; 95% confidence interval [CI], 78-80), as well as their organization (65%; 95% CI, 64-66), more than 42% (95% CI, 41-43) were considering leaving their organization in the next year or retiring before 2020; 4% of those were considering leaving for another job elsewhere in governmental public health. The majority of public health staff at SHA central offices are female (72%; 95% CI, 71-73), non-Hispanic white (70%; 95% CI, 69-71), and older than 40 years (73%; 95% CI, 72-74). The greatest training needs include influencing policy development, preparing a budget, and training related to the social determinants of health. PH WINS represents the first nationally representative survey of SHA employees. It holds significant potential to help answer previously unaddressed questions in public health

In this work, two new diacids, di(m-carboxyphenyl) succinate (m-dCPS) and di(o-carboxyphenyl) succinate (o-dCPS), were synthesized by reaction of m-, o-hydroxy benzoic acid with succinic chloride, respectively. Their corresponding copolymers with sebacic acid (SA), P(m-dCPS:SA) and P(o-dCPS:SA), were prepared by melt copolycondensation and characterized by NMR, UV and DSC methods. Compared with inherently fluorescent poly[di(p-carboxyphenyl) succinateco-sebacic anhydride] (P(p-dCPS:SA)), P(m-dCPS:SA) and P(o-dCPS:SA) displayed different luminescent properties. P(m-dCPS:SA) could emit fluorescence under the excitation of both visible and UV light, while P(o-dCPS:SA) could only emit fluorescence when excited with UV light. Degradation rate of the two new copolyanhydrides increased with the increase of SA fraction in the copolymers. In addition, P(o-dCPS:SA) degraded more rapidly than P(m-dCPS:SA) with the same composition. Typical surface-degradation characteristics of these copolyanhydrides were observed.

STATISTICAL MODELS OF REPRESENTING INTELLECTUAL CAPITAL

Directory of Open Access Journals (Sweden)

Andreea Feraru

2016-06-01

Full Text Available This article entitled Statistical Models of Representing Intellectual Capital approaches and analyses the concept of intellectual capital, as well as the main models which can support enterprisers/managers in evaluating and quantifying the advantages of intellectual capital. Most authors examine intellectual capital from a static perspective and focus on the development of its various evaluation models. In this chapter we surveyed the classical static models: Sveiby, Edvisson, Balanced Scorecard, as well as the canonical model of intellectual capital. Among the group of static models for evaluating organisational intellectual capital the canonical model stands out. This model enables the structuring of organisational intellectual capital in: human capital, structural capital and relational capital. Although the model is widely spread, it is a static one and can thus create a series of errors in the process of evaluation, because all the three entities mentioned above are not independent from the viewpoint of their contents, as any logic of structuring complex entities requires.

2018-02-06

Based on a survey of 9512 ninth-grade students conducted in Lower Saxony in 2013, this paper examines the prevalence of cyberbullying perpetration and the correlates of this behavior. Binary logistic multilevel regression was used in order to analyze correlates of sexual and psychological cyberbully perpetration. In the preceding semester, 2.4% of the adolescents were perpetrators of psychological cyberbullying and 0.4% bullied someone online sexually. Low levels of empathy, frequent consumption of violent media, and being victims of aggressive online behaviors are correlated with the risk that a child will become a bully. Female adolescents are less likely than boys to engage in sexual cyberbullying perpetration, but they are more likely to engage in psychological cyberbullying perpetration. Only a small share of adolescents engage in sexual and psychological cyberbullying perpetration. Both behaviors differ in their correlates, however being a victim of aggressive online behaviors increase the risk for perpetration of both behaviors, respectively.

Identifying Risk Factors for Recent HIV Infection in Kenya Using a Recent Infection Testing Algorithm: Results from a Nationally Representative Population-Based Survey.

Directory of Open Access Journals (Sweden)

Andrea A Kim

Full Text Available A recent infection testing algorithm (RITA that can distinguish recent from long-standing HIV infection can be applied to nationally representative population-based surveys to characterize and identify risk factors for recent infection in a country.We applied a RITA using the Limiting Antigen Avidity Enzyme Immunoassay (LAg on stored HIV-positive samples from the 2007 Kenya AIDS Indicator Survey. The case definition for recent infection included testing recent on LAg and having no evidence of antiretroviral therapy use. Multivariate analysis was conducted to determine factors associated with recent and long-standing infection compared to HIV-uninfected persons. All estimates were weighted to adjust for sampling probability and nonresponse.Of 1,025 HIV-antibody-positive specimens, 64 (6.2% met the case definition for recent infection and 961 (93.8% met the case definition for long-standing infection. Compared to HIV-uninfected individuals, factors associated with higher adjusted odds of recent infection were living in Nairobi (adjusted odds ratio [AOR] 11.37; confidence interval [CI] 2.64-48.87 and Nyanza (AOR 4.55; CI 1.39-14.89 provinces compared to Western province; being widowed (AOR 8.04; CI 1.42-45.50 or currently married (AOR 6.42; CI 1.55-26.58 compared to being never married; having had ≥ 2 sexual partners in the last year (AOR 2.86; CI 1.51-5.41; not using a condom at last sex in the past year (AOR 1.61; CI 1.34-1.93; reporting a sexually transmitted infection (STI diagnosis or symptoms of STI in the past year (AOR 1.97; CI 1.05-8.37; and being aged <30 years with: 1 HSV-2 infection (AOR 8.84; CI 2.62-29.85, 2 male genital ulcer disease (AOR 8.70; CI 2.36-32.08, or 3 lack of male circumcision (AOR 17.83; CI 2.19-144.90.

Most adolescents begin alcohol consumption during adolescence, heavy alcohol use by adolescents is common, and alcohol-related harm amongst adolescents is a major public health burden. Parents are a common source of alcohol amongst adolescents, but little is known about how parental supply of alcohol has changed over recent years. This study examines national trends in parental supply of alcohol to adolescent children in Australia since 1998. Six Australian National Drug Strategy Household Surveys (1998-2013) yielded rates of parental supply of current and first ever alcohol consumed. Lifetime and current alcohol use were also estimated. The surveys were conducted for households across all Australian states and territories. Surveyed adolescents were aged 14-17 years (N = 7357, 47.6 % male). Measures included the reported source of currently consumed alcohol and first ever alcoholic beverage (parents/friends/others), lifetime alcohol use, number of standard alcohol units consumed on drinking days, and frequency of alcohol use. Corrected Pearson chi-squared tests were used to compare survey years. There was a significant drop in parental supply of current alcohol use from 21.3 % in 2004 to 11.79 % in 2013 (p supply coincided with legislative changes on parental supply of alcohol to adolescents, but causality cannot be established because of the variation in the timing and reach of parental supply legislation, and small samples in some states. There were downward trends in adolescent experimentation, quantity and frequency of alcohol use across years, with the largest drop in alcohol use in 2010 and 2013. In Australia, there has been a substantial reduction in parental supply of alcohol to adolescents from 2010, and this factor may partially account for reductions in adolescent alcohol use.

Research has indicated that many video games are saturated with stereotypes of women and that these contents may cultivate sexism. The purpose of this study was to assess the relationship between video game exposure and sexism for the first time in a large and representative sample. Our aim was also to measure the strength of this association when two other significant and well-studied sources of sexism, television exposure and religiosity, were also included in a multivariate model. A representative sample of 13520 French youth aged 11-19 years completed a survey measuring weekly video game and television exposure, religiosity, and sexist attitudes toward women. Controlling for gender and socioeconomic level, results showed that video game exposure and religiosity were both related to sexism. Implications of these results for future research on sexism in video games are discussed.

We perform an analysis of photometric redshifts estimated by using a non-representative training sets in magnitude space. We use the ANNz2 and GPz algorithms to estimate the photometric redshift both in simulations as well as in real data from the Sloan Digital Sky Survey (DR12). We show that for the representative case, the results obtained by using both algorithms have the same quality, either using magnitudes or colours as input. In order to reduce the errors when estimating the redshifts with a non-representative training set, we perform the training in colour space. We estimate the quality of our results by using a mock catalogue which is split samples cuts in the r-band between 19.4 manage to define a photometric estimator which fits well the spectroscopic distribution of galaxies in the mock testing set, but with a larger scatter. To complete this work, we perform an analysis of the impact on the detection of clusters via density of galaxies in a field by using the photometric redshifts obtained with a non-representative training set.

For the past five years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). Eligible projects have ranged from grape-based plasma production in a microwave oven to observation of the effects of viscosity in a fluid model of quark-gluon plasma. Most projects have been aimed at applications, including fusion, thrusters, lighting, materials processing, and GPS improvements. However diagnostics (spectroscopy), technology (magnets), and theory (quark-gluon plasmas) have also been represented. All of the CPS award-winning projects so far have been based on experiments, with two awards going to women students and three to men. Since the award was initiated, both the number and quality of plasma projects has increased. The CPS expects this trend to continue, and looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2010 fair in San Jose on May 11-12.

To look at the trends in prevalence of generalised (body mass index (BMI) ≥ 25 kg/m2) and abdominal obesity (waist circumference (WC) >102 cm, men; > 88 cm, women) among older people from 1993 to 2008, prevalence of chronic disease by overweight/obesity and WC categories in England 2005 and evaluate the association of these measures with chronic diseases. Analyses of nationally representative cross-sectional population surveys, the Health Survey for England (HSE). Non-institutionalised men and women aged ≥ 65 years (in HSE 2005, 1512 men and 1747 women). Height, weight, waist circumference, blood pressure measurements were taken according to standardised HSE protocols. Information collected on socio-demographic, health behaviour and doctor diagnosed health conditions. Generalised obesity and abdominal obesity increased among men and women from 1993 to 2008. In 2005, the HSE 2005 focussed on older people. 72% of men and 68% of women aged over 65 were either overweight or obese. Prevalence of raised WC was higher in women (58%) than in men (46%). The prevalence of diabetes and arthritis was higher in people with generalised obesity in both sexes. Men were more likely to have had a joint replacement and had a higher prevalence of stroke if they were overweight only but women were more likely to have had a joint replacement only if they were obese (13%) and had a higher risk of falls with generalised obesity. The pattern was similar for the prevalence of chronic diseases by raised WC. Multivariate analysis showed that generalised and abdominal obesity was independently associated with risk of hypertension, diabetes and arthritis in both men and women. In women only, there was an association between generalised obesity and having a fall in the last year (OR: 1.5), and between abdominal obesity and having a joint replacement (OR: 1.9, p=0.01). Complications of obesity such as diabetes, hypertension and arthritis, are more common in men and women aged over 65 who are

Full Text Available This article evaluates the effect of the choice of survey recruitment mode on the value of water quality in lakes, rivers, and streams. Four different modes are compared: bringing respondents to one central location after phone recruitment, mall intercepts in two states, national phone-mail survey, and an Internet survey with a national, probability-based panel. The modes differ in terms of the representativeness of the samples, non-response rates, sample selection effects, and consistency of responses. The article also shows that the estimated value of water quality can differ substantially depending on the survey mode. The national Internet panel has the most desirable properties with respect to performance on the four important survey dimensions of interest.

The nature of community pharmacy is changing, shifting from the preparation and distribution of medicines to the provision of cognitive pharmaceutical services (CPS); however, often the provision of traditional services leaves little time for innovative services. This study investigated the time community pharmacists spend on the tasks and activities of daily practice and to what extent they are able to implement CPS-related services in daily practice. Self-reporting work sampling was used to register the activities of community pharmacists. A smartphone application, designed specifically for this purpose, alerted participants to register their current activity five times per working day for 6 weeks. Participants also completed an online survey about baseline characteristics. Ninety-one Dutch community pharmacists provided work-sampling data (7848 registered activities). Overall, 51.5% of their time was spent on professional activities, 35.4% on semi-professional activities, and 13.1% on non-professional activities. The proportion of time devoted to CPS decreased during the workweek, whereas the time spent on traditional task increased. This study shows it is feasible to collect work-sampling data using smartphone technology. Community pharmacists spent almost half of their time on semi-professional and non-professional activities, activities that could be delegated to other staff members. In practice, the transition to CPS is hampered by competing traditional tasks, which prevents community pharmacists from profiling themselves as pharmaceutical experts in daily practice.

1989-01-01

The Florida Institute of Phosphate Research (FIPR) recently sponsored a statewide survey to identify all significant land areas in Florida where the state's environmental radiation rule should be applied. Under this rule, newly constructed buildings must be tested for radiation levels unless approved construction techniques are used. Two parallel surveys - a land-based survey and a population-based survey - were designed and conducted to address the objective. Each survey included measurements in more than 3000 residences throughout the state. Other information sources that existed at the outset of the study, such as geologic profiles mapped by previous investigators and terrestrial uranium levels characterized through aerial gamma radiation surveys, were also examined. Initial data analysis efforts focused on determining the extent of evidence of radon potential for each of 67 counties in the state. Within 18 countries that were determined to have definite evidence of elevated radon potential, more detailed spatial analyses were conducted to identify areas of which the rule should apply. A total of 74 quadrangles delineated by the U.S. Geological Survey, representing about 7% of those constituting the state, were identified as having elevated radon potential and being subject to the rule

Despite social media use being one of the most popular activities among adolescents, prevalence estimates among teenage samples of social media (problematic) use are lacking in the field. The present study surveyed a nationally representative Hungarian sample comprising 5,961 adolescents as part of the European School Survey Project on Alcohol and Other Drugs (ESPAD). Using the Bergen Social Media Addiction Scale (BSMAS) and based on latent profile analysis, 4.5% of the adolescents belonged to the at-risk group, and reported low self-esteem, high level of depression symptoms, and elevated social media use. Results also demonstrated that BSMAS has appropriate psychometric properties. It is concluded that adolescents at-risk of problematic social media use should be targeted by school-based prevention and intervention programs.

Peer crowds are macro-level subcultures that share similarities across geographic areas. Over the past decade, dozens of studies have explored the association between adolescent peer crowds and risk behaviors, and how they can inform public health efforts. However, despite the interest, researchers have not yet reported on crowd size and risk levels from a representative sample, making it difficult for practitioners to apply peer crowd science to interventions. The current study reports findings from the first statewide representative sample of adolescent peer crowd identification and health behaviors. Weighted data were analyzed from the 2015 Virginia Youth Survey of Health Behaviors ( n = 4,367). Peer crowds were measured via the I-Base Survey™, a photo-based peer crowd survey instrument. Frequencies and confidence intervals of select behaviors including tobacco use, substance use, nutrition, physical activity, and violence were examined to identify high- and low-risk crowds. Logistic regression was used to calculate adjusted odds ratios for each crowd and behavior. Risky behaviors clustered in two peer crowds. Hip Hop crowd identification was associated with substance use, violence, and some depression and suicidal behaviors. Alternative crowd identification was associated with increased risk for some substance use behaviors, depression and suicide, bullying, physical inactivity, and obesity. Mainstream and, to a lesser extent, Popular, identities were associated with decreased risk for most behaviors. Findings from the first representative study of peer crowds and adolescent behavior identify two high-risk groups, providing critical insights for practitioners seeking to maximize public health interventions by targeting high-risk crowds.

Representativeness of the LifeLines Cohort Study.

Full Text Available LifeLines is a large prospective population-based three generation cohort study in the north of the Netherlands. Different recruitment strategies were adopted: recruitment of an index population via general practitioners, subsequent inclusion of their family members, and online self-registration. Our aim was to investigate the representativeness of the adult study population at baseline and to evaluate differences in the study population according to recruitment strategy.Demographic characteristics of the LifeLines study population, recruited between 2006-2013, were compared with the total adult population in the north of the Netherlands as registered in the Dutch population register. Socioeconomic characteristics, lifestyle, chronic diseases, and general health were further compared with participants of the Permanent Survey of Living Conditions within the region (2005-2011, N = 6,093. Differences according to recruitment strategy were assessed.Compared with the population of the north of the Netherlands, LifeLines participants were more often female, middle aged, married, living in a semi-urban place and Dutch native. Adjusted for differences in demographic composition, in LifeLines a smaller proportion had a low educational attainment (5% versus 14% or had ever smoked (54% versus 66%. Differences in the prevalence of various chronic diseases and low general health scores were mostly smaller than 3%. The age profiles of the three recruitment groups differed due to age related inclusion criteria of the recruitment groups. Other differences according to recruitment strategy were small.Our results suggest that, adjusted for differences in demographic composition, the LifeLines adult study population is broadly representative for the adult population of the north of the Netherlands. The recruitment strategy had a minor effect on the level of representativeness. These findings indicate that the risk of selection bias is low and that risk estimates

Obtaining Samples Representative of Contaminant Distribution in an Aquifer

International Nuclear Information System (INIS)

Schalla, Ronald; Spane, Frank A.; Narbutovskih, Susan M.; Conley, Scott F.; Webber, William D.

2002-01-01

Historically, groundwater samples collected from monitoring wells have been assumed to provide average indications of contaminant concentrations within the aquifer over the well-screen interval. In-well flow circulation, heterogeneity in the surrounding aquifer, and the sampling method utilized, however, can significantly impact the representativeness of samples as contaminant indicators of actual conditions within the surrounding aquifer. This paper identifies the need and approaches essential for providing cost-effective and technically meaningful groundwater-monitoring results. Proper design of the well screen interval is critical. An accurate understanding of ambient (non-pumping) flow conditions within the monitoring well is essential for determining the contaminant distribution within the aquifer. The ambient in-well flow velocity, flow direction and volumetric flux rate are key to this understanding. Not only do the ambient flow conditions need to be identified for preferential flow zones, but also the probable changes that will be imposed under dynamic conditions that occur during groundwater sampling. Once the in-well flow conditions are understood, effective sampling can be conducted to obtain representative samples for specific depth zones or zones of interest. The question of sample representativeness has become an important issue as waste minimization techniques such as low flow purging and sampling are implemented to combat the increasing cost of well purging and sampling at many hazardous waste sites. Several technical approaches (e.g., well tracer techniques and flowmeter surveys) can be used to determine in-well flow conditions, and these are discussed with respect to both their usefulness and limitations. Proper fluid extraction methods using minimal, (low) volume and no purge sampling methods that are used to obtain representative samples of aquifer conditions are presented

Alcohol marketing and drunkenness among students in the Philippines: findings from the nationally representative Global School-based Student Health Survey

Science.gov (United States)

2013-01-01

Background A largely unaddressed issue in lower income countries and the Philippines, in particular, is the role of alcohol marketing and its potential link to early alcohol use among youth. This study examines the associations between exposures to alcohol marketing and Filipino youths’ drinking prevalence and drunkenness. Methods Cross-sectional analyses were used to examine the Global School-based Student Health Survey (GSHS) conducted in Philippines (2011). The self-administered questionnaires were completed by students primarily 13 to 16 years of age (N = 5290). Three statistical models were computed to test the associations between alcohol marketing and alcohol use, while controlling for possible confounding factors. Results Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR: 1.84; 95% CI = 1.06–3.21) among youths after controlling for demographic and psychosocial characteristics, peer environment, and risky behaviors. In addition, seeing alcohol ads in newspapers and magazines (AOR: 1.65, 95% CI = 1.05–2.58) and seeing ads at sports events, concerts or fairs (AOR: 1.50, 95% CI = 1.06–2.12) were significantly associated with increased reports of drunkenness. Conclusions There are significant associations between alcohol marketing exposure and increased alcohol use and drunkenness among youth in the Philippines. These findings highlight the need to put policies into effect that restrict alcohol marketing practices as an important prevention strategy for reducing alcohol use and its dire consequences among vulnerable youth.

Explaining discrepancies in reproductive health indicators from population-based surveys and exit surveys: a case from Rwanda.

Science.gov (United States)

Meekers, D; Ogada, E A

2001-06-01

Reproductive health programmes often need exit surveys and population-based surveys for monitoring and evaluation. This study investigates why such studies produce discrepant estimates of condom use, sexual behaviour and condom brand knowledge, and discusses the implications for future use of exit surveys for programme monitoring. Logistic regression is used to explain differences between a household survey of 1295 persons and an exit survey among a random sample of 2550 consumers at retail outlets in RWANDA: Discrepancies in ever use of condoms and risky sexual behaviours are due to differences in socioeconomic status of the two samples. After controls, exit surveys at most outlet types have the same results as the household survey. Only exit surveys at bars, nightclubs and hotels yield significantly different estimates. However, the above-average knowledge of Prudence Plus condoms in the exit interviews is not attributable to socioeconomic or demographic variables, most likely because respondents have seen the product at the outlets. Information about condom use and sexual behaviour obtained from exit surveys appears as accurate as that obtained through household surveys. Nevertheless, exit surveys must be used cautiously. Because exit surveys may include wealthier and better-educated respondents, they are not representative of the general population. The composition of exit survey samples should be validated through existing household surveys. Comparisons across survey types are generally unadvisable, unless they control for sample differences. When generalizing to the population at large is not needed (e.g. for studies aimed at identifying the characteristics and behaviour of users of particular products or services), exit surveys can provide an appropriate alternative to household surveys.

2010-01-01

A Digital Survey Meter based on PIC16F628 Microcontroller was designed using simple Geiger-Muller Counter ZP1320 made by Centronic in the UK as detector. The sensitivity of this tube is about 9 counts/s at 10μGy/h. It is sensitive to gamma and beta particles over 0.25 MeV. It has a sensitive length of 28mm. Count rate versus dose rate is quite linear up to about 10 4 counts/s. Indication is given by a speaker which emits one click for each count. In addition to the acoustic alarm, the meter works according one of three different measurement modes selected using appropriate 3 states switch: 1- Measurement of Dose rate ( in μGy/h) and counting rate ( in CPS) , for High counting rates. 2- Measurement of Dose rate ( in μGy/h) and counting rate ( in CPM), for Low counting rates. 3- Accumulated Counting with continues display for No. of Counts and Counting Time with a period of 2 Sec. The results are Displayed on an Alphanumerical LCD Display, and the circuit will give many hours of operation from a single 9V PP3 battery. The design of the circuit combines between accuracy, simplicity and low power consumption. We built 2 Models of this design, the first only with an internal detector, and the second is equipped with an External Detector. (author)

GUASOM is a data mining tool designed for knowledge discovery in large astronomical spectrophotometric archives developed in the framework of Gaia DPAC (Data Processing and Analysis Consortium). Our tool is based on a type of unsupervised learning Artificial Neural Networks named Self-organizing maps (SOMs). SOMs permit the grouping and visualization of big amount of data for which there is no a priori knowledge and hence they are very useful for analyzing the huge amount of information present in modern spectrophotometric surveys. SOMs are used to organize the information in clusters of objects, as homogeneously as possible according to their spectral energy distributions, and to project them onto a 2D grid where the data structure can be visualized. Each cluster has a representative, called prototype which is a virtual pattern that better represents or resembles the set of input patterns belonging to such a cluster. Prototypes make easier the task of determining the physical nature and properties of the objects populating each cluster. Our algorithm has been tested on the ALHAMBRA survey spectrophotometric observations, here we present our results concerning the survey segmentation, visualization of the data structure, separation between types of objects (stars and galaxies), data homogeneity of neurons, cluster prototypes, redshift distribution and crossmatch with other databases (Simbad).

Full Text Available Colubrid snakes of the South American genus Phalotris are difficult to detect because of their secretive habits, and thus they are poorly represented in collections. The species Phalotris cuyanus and P. tricolor, the southernmost representatives of the tricolor species group, were studied to determine the limits of intraspecific variation of P. cuyanus and to consolidate the taxonomic relationship between both species, the phenetically and geographically closest members in the group. The distribution of selected external characters (cephalic, ventral and subcaudal scales, coloration pattern, width of white and black collars, and hemipenis morphology were analyzed. Comparative data on the other members of the group, P. mertensi and P. matogrossensis, are briefly discussed. Males of P. cuyanus have a higher number of ventral scales than males of P. tricolor (mean of 220.3 vs. 204.6. Cephalic melanism varies among individuals and does not have discriminant orgeographic value for this species group. The white nuchal collar may partially cover the parietal scales in the four species. The black collar is moderately narrow in P. cuyanus, but it can be up to 12 scales wide in P. tricolor. Vertebral dotting is neither constant nor exclusive of any species. The four species of the group are wellcharacterized by combinations of character states for each one. We suggest considering to P. cuyanus as an evolutionary species typical of the Monte biogeographic province.

Full Text Available Abstract Background Musculoskeletal impairment (MSI is an important cause of morbidity and mortality worldwide, especially in developing countries. Prevalence studies for MSI in the developing world have used varying methodologies and are seldom directly comparable. This study aimed to develop a new tool to screen for and diagnose MSI and to pilot test the methodology for a national survey in Rwanda. Methods A 7 question screening tool to identify cases of MSI was developed through literature review and discussions with healthcare professionals. To validate the tool, trained rehabilitation technicians screened 93 previously identified gold standard 'cases' and 86 'non cases'. Sensitivity, specificity and positive predictive value were calculated. A standardised examination protocol was developed to determine the aetiology and diagnosis of MSI for those who fail the screening test. For the national survey in Rwanda, multistage cluster random sampling, with probability proportional to size procedures will be used for selection of a cross-sectional, nationally representative sample of the population. Households to be surveyed will be chosen through compact segment sampling and all individuals within chosen households will be screened. A pilot survey of 680 individuals was conducted using the protocol. Results: The screening tool demonstrated 99% sensitivity and 97% specificity for MSI, and a positive predictive value of 98%. During the pilot study 468 out of 680 eligible subjects (69% were screened. 45 diagnoses were identified in 38 persons who were cases of MSI. The subjects were grouped into categories based on diagnostic subgroups of congenital (1, traumatic (17, infective (2 neurological (6 and other acquired(19. They were also separated into mild (42.1%, moderate (42.1% and severe (15.8% cases, using an operational definition derived from the World Health Organisation's International Classification of Functioning, Disability and Health

Objective To provide an overview of beverage consumption patterns using the first nationally representative survey of dietary intake in Brazil. Design Beverage consumption data were obtained by 1-day food records in an individual dietary survey. Setting nationwide cross-sectional survey, 2008–09. Subjects nationally representative sample of individuals ≥10 years (n=34,003). Results Beverages contributed to 17.1% of total energy consumption. Caloric coffee beverages provided the greatest level of energy overall (464 kJ or 111 kcal/d). Individuals from 10 to 18 (243 kJ or 58 kcal/d) and from 19 to 39 years old (230 kJ or 55 kcal/d consumed higher proportion of energy from sugar sweetened soft drinks than individuals over this age (142 kJ or 34 kcal/d for those 40–59 and 79 kJ or 19 kcal/d for those >60 years old). Conclusions Overall, the contribution of beverages, particularly sugary beverages, to total energy consumption in Brazil represents an important public health challenge and is comparable with those from other countries.

Current priorities for diarrhoeal disease prevention include use of sanitation and safe water. There have been few attempts to quantify the importance of animal faeces in drinking-water contamination, despite the presence of potentially water-borne zoonotic pathogens in animal faeces. This study aimed to quantify the relationship between livestock ownership and point-of-consumption drinking-water contamination. Data from nationally representative household surveys in Nepal, Bangladesh, and Ghana, each with associated water quality assessments, were used. Multinomial regression adjusting for confounders was applied to assess the relationship between livestock ownership and the level of drinking-water contamination with E. coli. Ownership of five or more large livestock (e.g. cattle) was significantly associated with drinking-water contamination in Ghana (RRR=7.9, 95% CI=1.6 to 38.9 for medium levels of contamination with 1-31cfu/100ml; RRR=5.2, 95% CI=1.1-24.5 for high levels of contamination with >31cfu/100ml) and Bangladesh (RRR=2.4, 95% CI=1.3-4.5 for medium levels of contamination; non-significant for high levels of contamination). Ownership of eight or more poultry (chickens, guinea fowl, ducks or turkeys) was associated with drinking-water contamination in Bangladesh (RRR=1.5, 95% CI=1.1-2.0 for medium levels of contamination, non-significant for high levels of contamination). These results suggest that livestock ownership is a significant risk factor for the contamination of drinking-water at the point of consumption. This indicates that addressing human sanitation without consideration of faecal contamination from livestock sources will not be sufficient to prevent drinking-water contamination.

How Has Elderly Migration Changed in the Twenty-First Century? What the Data Can-and Cannot-Tell Us.

Science.gov (United States)

Conway, Karen Smith; Rork, Jonathan C

2016-08-01

Interstate elderly migration has strong implications for state tax policies and health care systems, yet little is known about how it has changed in the twenty-first century. Its relative rarity requires a large data set with which to construct reliable measures, and the replacement of the U.S. Census long form (CLF) with the American Community Survey (ACS) has made such updates difficult. Two commonly used alternative migration data sources-the Current Population Survey (CPS) and the Statistics of Income (SOI) program of the Internal Revenue Service (IRS)-suffer serious limitations in studying the migration of any subpopulation, including the elderly. Our study informs migration research in the post-2000 era by identifying methodological differences between data sources and devising strategies for reconciling the CLF and ACS. Our investigation focusing on the elderly suggests that the ACS can generate comparable migration data that reveal a continuation of previously identified geographic patterns as well as changes unique to the 2000s. However, its changed definition of residence and survey timing leaves us unable to construct a comparable national migration rate, suggesting that one must use national trends in the smaller CPS to investigate whether elderly migration has increased or decreased in the twenty-first century.

The INSuLa project consisted of a national survey on health and safety at work involving all the relevant actors such as workers, employers, occupational physicians (MC), worker safety representatives (RLS), prevention and safety service in the workplace (SPSAL). The survey aimed, on one hand, at investigating workers' risk perceptions at the workplace and, on another hand, at exploring the general level of awareness about the enforcement of the Legislative Decree 81/2008 and subsequent amendments. The survey was conducted on a stratified sample of8000 workers representative of the national situation taking into consideration some of the most important socio-demographic and occupational variables, such as gender, geographic area, age, type of contract and sector of activity. The analysis of the results presented here and the subsequent secondary analyses will contribute to identify the needs and critical issues for implementing preventive interventions at the workplaces, also in consideration of the emerging risks and changes in the world of work.

A survey of variational principles

International Nuclear Information System (INIS)

Lewins, J.D.

1993-01-01

In this article survey of variational principles has been given. Variational principles play a significant role in mathematical theory with emphasis on the physical aspects. There are two principals used i.e. to represent the equation of the system in a succinct way and to enable a particular computation in the system to be carried out with greater accuracy. The survey of variational principles has ranged widely from its starting point in the Lagrange multiplier to optimisation principles. In an age of digital computation, these classic methods can be adapted to improve such calculations. We emphasize particularly the advantage of basic finite element methods on variational principles.

Highlights: • We review the toxic effects of chlorophenols (CPs) and underlying mechanisms in fish. • CPs induce lethal effects, oxidative stress, endocrine disruption, reproductive toxicity and apoptosis in fish. • CPs exhibit toxicity through multiple signaling pathways in fish and different pathways co-exist under the same conditions. • Studies on DNA methylation provide new insights into our understanding of epigenetic mechanisms of CPs-induced toxicity. • Mechanisms studies on CPs toxicity performed under environmental concentrations need more attentions. - Abstract: Chlorophenols (CPs) are ubiquitous contaminants in the environment primarily released from agricultural and industrial wastewater. These compounds are not readily degraded naturally, and easily accumulate in organs, tissues and cells via food chains, further leading to acute and chronic toxic effects on aquatic organisms. Herein, we review the available literature regarding CP toxicity in fish, with special emphasis on the potential toxic mechanisms. CPs cause oxidative stress via generation of reactive oxygen species, induction of lipid peroxidation and/or oxidative DNA damage along with inhibition of antioxidant systems. CPs affect immune system by altering the number of mature B cells and macrophages, while suppressing phagocytosis and down-regulating the expression of immune factors. CPs also disrupt endocrine function by affecting hormone levels, or inducing abnormal gene expression and interference with hormone receptors. CPs at relatively higher concentrations induce apoptosis via mitochondria-mediated pathway, cell death receptor-mediated pathway, and/or DNA damage-mediated pathway. CPs at relatively lower concentrations promote cell proliferation, and foster cancers-prone environment by increasing the rate of point mutations and oxidative DNA lesions. These toxic effects in fish are induced directly by CPs per se or indirectly by their metabolic products. In addition, recent

2012-03-01

The capsular polysaccharide (CPS) of the important oral streptococcus Streptococcus anginosus, which causes endocarditis, and the genes for its synthesis have not been clarified. In this study, we investigated the gene locus required for CPS synthesis in S. anginosus. Southern hybridization using the cpsE gene of the well-characterized bacterium S. agalactiae revealed that there is a similar gene in the genome of S. anginosus. By using the colony hybridization technique and inverse PCR, we isolated the CPS synthesis (cps) genes of S. anginosus. This gene cluster consisted of genes containing typical regulatory genes, cpsA-D, and glycosyltransferase genes coding for glucose, rhamnose, N-acetylgalactosamine, and galactofuranose transferases. Furthermore, we confirmed that the cps locus is required for CPS synthesis using a mutant strain with a defective cpsE gene. The cps cluster was found to be located downstream the nrdG gene, which encodes ribonucleoside triphosphate reductase activator, as is the case in other oral streptococci such as S. gordonii and S. sanguinis. However, the location of the gene cluster was different from those of S. pneumonia and S. agalactiae. Copyright © 2011 The Society for Biotechnology, Japan. Published by Elsevier B.V.

The present study examined the association between having older siblings who gamble and adolescent at-risk/problem gambling and how parents (i.e., parental knowledge of their whereabouts) and peers might moderate such effects. Data were drawn from the ESPAD ® Italia2012 survey (European School Survey Project on Alcohol and Other Drugs) comprising a nationally representative Italian sample of adolescents. The analysis was carried out on a subsample of 10,063 Italian students aged 15-19 years (average age = 17.10; 55 % girls) who had at least one older sibling and who had gambled at some point in their lives. Respondents' problem gambling severity, older gambler sibling, gambler peers, parental knowledge, and socio-demographic characteristics were individually assessed. Multinomial logistic regression analyses including two- and three-way interactions were conducted. The odds of being an at-risk/problem gambler were higher among high school students with older siblings that gambled and those with peers who gambled. Higher parental knowledge (of who the adolescent was with and where they were in their leisure time) was associated with lower rates of at-risk/problem gambling. There was also an interaction between gamblers with older siblings and parental knowledge. The combination of having siblings who gambled and a greater level of parental knowledge was associated with lower levels of problem gambling. The present study confirmed the occurrence of social risk processes (older siblings and peers who gambled) and demonstrated that gambling among older siblings and peers represents an important contextual factor for increased at-risk/problem gambling. However, parental knowledge appears to be sufficient to counterbalance the influence of older siblings.

Problematic Social Media Use: Results from a Large-Scale Nationally Representative Adolescent Sample.

Directory of Open Access Journals (Sweden)

Full Text Available Despite social media use being one of the most popular activities among adolescents, prevalence estimates among teenage samples of social media (problematic use are lacking in the field. The present study surveyed a nationally representative Hungarian sample comprising 5,961 adolescents as part of the European School Survey Project on Alcohol and Other Drugs (ESPAD. Using the Bergen Social Media Addiction Scale (BSMAS and based on latent profile analysis, 4.5% of the adolescents belonged to the at-risk group, and reported low self-esteem, high level of depression symptoms, and elevated social media use. Results also demonstrated that BSMAS has appropriate psychometric properties. It is concluded that adolescents at-risk of problematic social media use should be targeted by school-based prevention and intervention programs.

Online recruitment is feasible, low-cost, and can provide high-quality epidemiological data. However, little is known about the feasibility of recruiting postpartum women online, or sample representativeness. The current study investigates the feasibility of recruiting a population of postpartum women online for health research and examines sample representativeness. Two samples of postpartum women were compared: those recruited online as participants in a brief survey of new mothers (n=1083) and those recruited face-to-face as part of a nationally representative study (n=579). Sociodemographic, general health, and mental health characteristics were compared between the two samples. Obtaining a sample of postpartum women online for health research was highly efficient and low-cost. The online sample over-represented those who were younger (aged 25-29 years), were in a de facto relationship, had higher levels of education, spoke only English at home, and were first-time mothers. Members of the online sample were significantly more likely to have poor self-rated health and poor mental health than the nationally representative sample. Health differences remained after adjusting for sociodemographic differences. Potential exists for feasible and low-cost e-epidemiological research with postpartum populations; however, researchers should consider the potential influence of sample nonrepresentativeness. ©Liana S Leach, Peter Butterworth, Carmel Poyser, Philip J Batterham, Louise M Farrer.

The effects of health literacy are thought to be based on interactions between patients' skill levels and health care system demands. Little health literacy research has focused on attributes of health care organizations. We examined whether the attribute of individuals' experiences with front desk staff, patient engagement through bringing questions to a doctor visit, and health literacy skills were related to two patient-reported outcomes. We administered a telephone survey with two sampling frames (i.e., household landline, cell phone numbers) to a randomly selected statewide sample of 3358 English-speaking adult residents of Missouri. We examined two patient-reported outcomes - whether or not respondents reported knowing more about their health and made better choices about their health following their last doctor visit. Multivariable logistic regression models were used to examine the independent contributions of predictor variables (i.e., front desk staff, bringing questions to a doctor visit, health literacy skills). Controlling for self-reported health, having a personal doctor, time since last visit, number of chronic conditions, health insurance, and sociodemographic characteristics, respondents who had a good front desk experience were 2.65 times as likely (95% confidence interval [CI]: 2.13, 3.30) and those who brought questions were 1.73 times as likely (95% CI: 1.32, 2.27) to report knowing more about their health after seeing a doctor. In a second model, respondents who had a good front desk experience were 1.57 times as likely (95% CI: 1.26, 1.95) and those who brought questions were 1.66 times as likely (95% CI: 1.29, 2.14) to report making better choices about their health after seeing a doctor. Patients' health literacy skills were not associated with either outcome. Results from this representative statewide survey may indicate that one attribute of a health care organization (i.e., having a respectful workforce) and patient engagement through

A method to generate generic floor response spectra for operating nuclear power plants

A free-field earthquake response spectra was used to generate horizontal earthquake time histories. The excitation was applied through the soil and into the various structures to produce responses in equipment. An entire range of soil conditions was used with each structure, from soft soil to solid rock. Actual PWR and BWR - Mark I structural models were used as representative of a class of structures. For each model, the stiffness properties were varied, with the same mass, so as to extend the fundamental base structure natural frequency from 2 cps to 36 cps. This resulted in fundamental mode coupled natural frequencies as low as 0.86 cps and as high as 30 cps. From all of these models of soils and structures, floor response spectra were generated at each floor level. The natural frequencies of the structures were varied to obtain maximum response conditions. The actual properties were first used to locate the natural frequencies. The stiffness properties were than varied, with the same mass, to extend the range of the fundamental base structure natural frequency. The intention was to have the coupled structural material frequencies in the vicinity of the peak amplitude frequency content of the excitation spectrum. Particular attention was therefore given to the frequency band between 2 Hz and 4 Hz. A horizontal generic floor response spectra is proposed for the top level of a generic structure. Reduction factors are applied to the peak acceleration for equipment at lower levels. (orig./HP)

Independent inventors are important but little-researched members of the US technical community. The survey reported on here is the first in modern times to attempt to provide a profile of the US independent inventor that goes beyond a single geographical or organizational locale. The report that follows provides an overview of the demographics, practices and concerns of the modern US inventor as represented by the members of leading US inventor organizations. It is by no means comprehensive but seeks to be indicative of the issues raised in the survey each which will be dealt with more comprehensively in future publications.

Is the cluster risk model of parental adversities better than the cumulative risk model as an indicator of childhood physical abuse?: findings from two representative community surveys.

Science.gov (United States)

Fuller-Thomson, E; Sawyer, J-L

2014-01-01

Screening strategies for childhood physical abuse (CPA) need to be improved in order to identify those most at risk. This study uses two regionally representative community samples to examine whether a cluster or cumulative model of risk indicators (i.e. parental divorce, parental unemployment, and parental addictions) explains a larger proportion of the variation in CPA. Data were drawn from Statistics Canada's National Population Health Survey (1994-1995) and Canadian Community Health Survey 3.1 (2005). Response rates were greater than 80% in both samples. Each survey had approximately 13,000 respondents aged 18 and over who answered questions about the above adverse childhood experiences. A gradient was shown with similar outcomes in each data set. Only 3.4% of adults who experienced none of the three risk indicators reported they had been physically abused during childhood or adolescence. The prevalence of CPA was greater among those who experienced parental divorce alone (8.3%-10.7%), parental unemployment alone (8.9%-9.7%) or parental addictions alone (18.0%-19.5%). When all three risk indicators were present, the prevalence of CPA ranged from 36.0%-41.0% and the age-sex-race adjusted odds were greater than 15 times that of individuals with none of the three risk indicators. The cluster model explained a statistically significantly larger proportion of the variation than the cumulative model although the difference between the two models was modest. For the purposes of parsimony, the cumulative model may be the better alternative. Adults who were exposed to two or more childhood risk indicators were much more likely to report that they were physically abused during their childhood than those with only one or no risk factors. Medical professionals may use this information on cumulative risk factors to more effectively target screening for potential CPA. Future research should include prospective studies. © 2012 John Wiley & Sons Ltd.

The BAT AGN Spectroscopic Survey (BASS)

2017-08-01

We present the Swift BAT AGN Spectroscopic Survey (BASS) and discus the first four papers. The catalog represents an unprecedented census of hard-X-ray selected AGN in the local universe, with ~90% of sources at zpast studies. Consistent with previous surveys, we find an increase in the fraction of un-obscured (type 1) AGN, as measured from broad Hbeta and Halpha, with increasing 14-195 keV and 2-10 keV luminosity. We find the FWHM of the emission lines to show broad agreement with the X-ray obscuration measurements. Compared to narrow line AGN in the SDSS, the X-ray selected AGN in our sample with emission lines have a larger fraction of dustier galaxies suggesting these types of galaxies are missed in optical AGN surveys using emission line diagnostics.

Results of investigation into running away current-plasma sheath (CPS) of noncylindrical Z-pinch are given. Experimental chamber was filled with neon up to 3 torr pressure. Store of energy was equal to 20 kJ. CPS radiation spectrum scanning was recorded in the phase of its convergence to the system axis by means of an electron-optical converter of the AGAT type. Electron temperature in the inflection region on CPS constituted 3 eV. Possibilities of magnetic field diffusion through neon CPS and appearance of CPS running away mode are shown. CPS plasma spectra indicated that radiation can be recorded only from a CPS head near-anode part and its external peripheral regions moving from the axis and emitting considerably less quantity of radiation

Histone H3 lysine 4 (H3K4) methylation is catalyzed by the highly evolutionarily conserved multiprotein complex known as Set1/COMPASS or MLL/COMPASS-like complexes from yeast to human, respectively. Here we have reconstituted fully functional yeast Set1/COMPASS and human MLL/COMPASS-like complex in vitro and have identified the minimum subunit composition required for histone H3K4 methylation. These subunits include the methyltransferase C-terminal SET domain of Set1/MLL, Cps60/Ash2L, Cps50/RbBP5, Cps30/WDR5, and Cps25/Dpy30, which are all common components of the COMPASS family from yeast to human. Three-dimensional (3D) cryo-EM reconstructions of the core yeast complex, combined with immunolabeling and two-dimensional (2D) EM analysis of the individual subcomplexes reveal a Y-shaped architecture with Cps50 and Cps30 localizing on the top two adjacent lobes and Cps60-Cps25 forming the base at the bottom. EM analysis of the human complex reveals a striking similarity to its yeast counterpart, suggesting a common subunit organization. The SET domain of Set1 is located at the juncture of Cps50, Cps30, and the Cps60-Cps25 module, lining the walls of a central channel that may act as the platform for catalysis and regulative processing of various degrees of H3K4 methylation. This structural arrangement suggested that COMPASS family members function as exo-methylases, which we have confirmed by in vitro and in vivo studies.

How to Maintain Computerized Procedure System in the same Version

International Nuclear Information System (INIS)

Jung, Yeon Sub

2016-01-01

CPS(Computerized Procedure System) has been introduced in advanced nuclear power plant worldwide. Korean CPS complies with this trend. It has been applied to Shinkori3,4 and all their successors including BNPP1,2,3,4. CPS is designed by KHNP CRI, and developed by Westinghouse or Doosan. Initial design has been improved by reflecting operator experience, human factor V and V, and advanced engineering method. Design improvement makes CPS differ from plant to plant. For example CPS in Shinhanul cannot interpret CP(Computerized Procedure) of ShinKori3, 4. Different CPS makes it difficult to utilize CP and train operators. Therefore it is important to keep CPS in single version. Note that typical text editors in the office are kept in single version. On the other hand, plant monitoring systems in main control room are actually different. Because CPS is positioned between text editor and monitoring system, goal to maintain CPS in single version is not an easy task. From Shinkori3,4, lots of improvements are achieved in CPS. This improvement surely makes operation easy and will not introduce human errors. Side effect of improvement is that PXS and CPS ES may not be compatible among nuclear power plants. So the side effect should be avoided by minimizing change of XML. Initial XML had been developed for Shinkori3,4. The XML has been modified slightly for Shinhanul1,2. PXS and CPS ES are being developed for the same version for all nuclear power plants of APR1400

2014-01-01

Background Nonprobability Web surveys using volunteer panels can provide a relatively cheap and quick alternative to traditional health and epidemiological surveys. However, concerns have been raised about their representativeness. Objective The aim was to compare results from different Web panels with a population-based probability sample survey (n=8969 aged 18-44 years) that used computer-assisted self-interview (CASI) for sensitive behaviors, the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3). Methods Natsal-3 questions were included on 4 nonprobability Web panel surveys (n=2000 to 2099), 2 using basic quotas based on age and sex, and 2 using modified quotas based on additional variables related to key estimates. Results for sociodemographic characteristics were compared with external benchmarks and for sexual behaviors and opinions with Natsal-3. Odds ratios (ORs) were used to express differences between the benchmark data and each survey for each variable of interest. A summary measure of survey performance was the average absolute OR across variables. Another summary measure was the number of key estimates for which the survey differed significantly (at the 5% level) from the benchmarks. Results For sociodemographic variables, the Web surveys were less representative of the general population than Natsal-3. For example, for men, the average absolute OR for Natsal-3 was 1.14, whereas for the Web surveys the average absolute ORs ranged from 1.86 to 2.30. For all Web surveys, approximately two-thirds of the key estimates of sexual behaviors were different from Natsal-3 and the average absolute ORs ranged from 1.32 to 1.98. Differences were appreciable even for questions asked by CASI in Natsal-3. No single Web survey performed consistently better than any other did. Modified quotas slightly improved results for men, but not for women. Conclusions Consistent with studies from other countries on less sensitive topics, volunteer Web

The impact of a Classroom Performance System on learning gains in a biology course for science majors

Science.gov (United States)

Marin, Nilo Eric

This study was conducted to determine if the use of the technology known as Classroom Performance System (CPS), specifically referred to as "Clickers", improves the learning gains of students enrolled in a biology course for science majors. CPS is one of a group of developing technologies adapted for providing feedback in the classroom using a learner-centered approach. It supports and facilitates discussion among students and between them and teachers, and provides for participation by passive students. Advocates, influenced by constructivist theories, claim increased academic achievement. In science teaching, the results have been mixed, but there is some evidence of improvements in conceptual understanding. The study employed a pretest-posttest, non-equivalent groups experimental design. The sample consisted of 226 participants in six sections of a college biology course at a large community college in South Florida with two instructors trained in the use of clickers. Each instructor randomly selected their sections into CPS (treatment) and non-CPS (control) groups. All participants filled out a survey that included demographic data at the beginning of the semester. The treatment group used clicker questions throughout, with discussions as necessary, whereas the control groups answered the same questions as quizzes, similarly engaging in discussion where necessary. The learning gains were assessed on a pre/post-test basis. The average learning gains, defined as the actual gain divided by the possible gain, were slightly better in the treatment group than in the control group, but the difference was statistically non-significant. An Analysis of Covariance (ANCOVA) statistic with pretest scores as the covariate was conducted to test for significant differences between the treatment and control groups on the posttest. A second ANCOVA was used to determine the significance of differences between the treatment and control groups on the posttest scores, after

Elucidation of terpenoid metabolism in Scoparia dulcis by RNA-seq analysis.

Yamamura, Yoshimi; Kurosaki, Fumiya; Lee, Jung-Bum

2017-03-07

Scoparia dulcis biosynthesize bioactive diterpenes, such as scopadulcic acid B (SDB), which are known for their unique molecular skeleton. Although the biosynthesis of bioactive diterpenes is catalyzed by a sequence of class II and class I diterpene synthases (diTPSs), the mechanisms underlying this process are yet to be fully identified. To elucidate these biosynthetic machinery, we performed a high-throughput RNA-seq analysis, and de novo assembly of clean reads revealed 46,332 unique transcripts and 40,503 two unigenes. We found diTPSs genes including a putative syn-copalyl diphosphate synthase (SdCPS2) and two kaurene synthase-like (SdKSLs) genes. Besides them, total 79 full-length of cytochrome P450 (CYP450) genes were also discovered. The expression analyses showed selected CYP450s associated with their expression pattern of SdCPS2 and SdKSL1, suggesting that CYP450 candidates involved diterpene modification. SdCPS2 represents the first predicted gene to produce syn-copalyl diphosphate in dicots. In addition, SdKSL1 potentially contributes to the SDB biosynthetic pathway. Therefore, these identified genes associated with diterpene biosynthesis lead to the development of genetic engineering focus on diterpene metabolism in S. dulcis.

Mobile Computerized Procedure System for the Improved Situation Awareness among Field Workers and Main Control Room Operators

International Nuclear Information System (INIS)

Lee, Sungjin; Seong, Nokyu; Jung, Yeonsub

2013-01-01

This paper explains the technical issues of the mobile CPS (m-CPS) in the conceptual development stage. The proposed m-CPS can be developed with many recent technologies in the various industry fields based on CRI CPS. Performance and stability of CRI CPS have been tested several times until now. It is expected that more human errors can be reduced by the m-CPS through improved situation awareness and human performance tools for local workers and MCR operators. Some considerations as well as mentioned ones will be reflected in the m-CPS development. Human errors can occur during the test and maintenance of the generator, safety injection system and reactor coolant inventory in nuclear power plants (NPPs). Most of human errors have been occurred by the omission of the prevention techniques such as the self-check, the peer-check, the concurrent verification and etc. Another important reason is the insufficient information sharing among main control room (MCR) operators and field workers. Various field service automation tools have been developed with recent information technology in many countries. APR1400 computerized procedure system (CPS) has been developed for the MCR operators of Shin-Kori 3 and 4 units. Especially, the concurrent verification support design is applied in the construction project of Shin-Hanul 1 and 2 CPS. KHNP central research institute (CRI) expects that the extended application of CPS including the field activity, that is a kind of mobile CPS, can enhance the reduction of human errors

Evidence-based clinical guidelines in Kyrgyz Republic.

Health from 31.12.2008 №704.This methodology was based on the international guideline SIGN-50 [3], as part of the strategy, it was decided to adapt clinical guidelines of the advanced countries of the world to the organizational characteristics of health care in the Kyrgyz Republic. According to the adopted methodology, the development of clinical guidelines should include the following steps: choose a theme, create a multidisciplinary group to conduct a search of existing clinical guidelines and assess their quality, if necessary, conduct an additional search of evidence, make recommendations and draw up the text of clinical guidelines, conduct peer review and consultations, approve clinical guidelines in the pilot, approve the clinical management of the Ministry of Health, publish and distribute, put into practice, monitor the effectiveness of implementation, provide for the revision and updating of clinical guidelines as new credible information appears. In the future, these CGs will be considered as a basis for the development of the CP in accordance with the possibilities of health care organizations of the country. Figuratively speaking, the CG answers the question - "What can be done in an ideal situation? ', And CP -" What should be done in a country?".The Ministry of Health over the period 2008-2014 years approved 41 CGs and 118 CPs for common diseases. It should be noted that only 31.7% of them were represented by the corresponding CGs. Among the approved CPs only 15.3% were based on the corresponding CGs. All of the CGs and CPs (100%) identified experts who prepared the documents and to whom they are addressed.

Two CPs ([Cd{sub 3}(BTC){sub 2}(TIB){sub 2}(H{sub 2}O){sub 4}].(H{sub 2}O){sub 2}){sub n} (1) and ([Zn{sub 3}(BTC){sub 2}(TIB){sub 2}].(H{sub 2}O){sub 6}){sub n} (2) composed of tripodal linkers BTC (1,3,5-benzenetricarboxylate) and TIB (1,3,5-tris(imidazol-1-ylmethyl)benzene) were synthesized via solvothermal route and structurally characterized. Single crystal structural analysis reveals 1 possesses a novel 3D framework structure, whereas 2 represents a previously established compound. Owing to the d{sup 10} configuration of metal nodes and robust 3D frameworks, 1 and 2 exhibit excellent fluorescence properties which have been exploited to sense organic nitro compounds in vapor phase. Compound 1 demonstrates selective sensing of nitromethane over structurally similar methanol with ca. 70 and 43% fluorescence quenching in case of former and later. Similarly, 58% fluorescence quenching was observed in case of nitrobenzene over the structurally resembling toluene for which 30% quenching was observed. Compound 2 did not show any preference for nitro compounds and exhibited comparable fluorescence quenching when exposed to the vapors of nitro or other geometrically resembling organic molecules. Furthermore, adsorption experiments revealed that 1 and 2 can uptake 2.74 and 14.14 wt% molecular iodine respectively in vapor phase which can be released in organic solvents such as hexane and acetonitrile. The maximal iodine uptake in case of 1 and 2 corresponds to 0.15 and 0.80 molecules of iodine per formula unit of respective frameworks. Comprehensive structural description, thermal stability and luminescence behavior for both CPs has also been presented. - Graphical abstract: Two 3D luminescent CPs comprising mixed tripodal ligands have been hydrothermally synthesized and structurally characterized. Iodine encapsulation capacity of synthesized CPs is evaluated and their fluorescence quenching in presence of small organic molecules is exploited for sensing of nitro

Unlike other technical disciplines, digital instrumentation and controls (DI and C) is a field which reflects the constant evolution in electrical and electronics technologies. The continual evolution in DI and C technology presents challenges for power plant operators, designers, suppliers, as well as the regulators. Contemporary regulations and guidance can be made either obsolete or insufficient as technology changes push the boundaries of what was originally considered or completely change the assumptions that were the foundation when they were first enacted. As such, producing timely and practical guidance is essential to the safe operation of nuclear plants. The goal of MDEP is not to independently develop new regulatory standards. The overall philosophy of MDEP DICWG is to use the collective knowledge and experiences from nuclear power regulatory organisations from around the world to effectively and efficiently create CPs to address current and future DI and C topics of concern to its member countries. The CPs provide an effective and efficient means to convey a general framework that includes input from both member countries and international standards organisations. Each CP produced by DICWG represents an agreed upon approach to address the specific topic for which it has been created. CPs are not legally binding and do not constitute additional obligations for the regulatory organisations or the licensees but are guidelines, recommendations or assessments that the MDEP participants agree are good to highlight during their safety reviews of new reactors. MDEP member countries may decide to implement the CPs through their own national regulatory processes. The topics that are addressed in current and upcoming CPs reflect a wide variety of technical topics that are challenging in the DI and C field and oftentimes require a holistic approach to reach resolution. The topics for CPs are selected based upon the use of DI and C in new reactor designs, issues of

Evaluation studies of population-based tobacco control interventions often rely on large-scale survey data from numerous respondents across many geographic areas to provide evidence of their effectiveness. Significant challenges for survey research have emerged with the evolving communications landscape, particularly for surveying hard-to-reach populations such as youth and young adults. This study combines the comprehensive coverage of an address-based sampling (ABS) frame with the timeliness of online data collection to develop a nationally representative longitudinal cohort of young people aged 15-21. We constructed an ABS frame, partially supplemented with auxiliary data, to recruit this hard-to-reach sample. Branded and tested mail-based recruitment materials were designed to bring respondents online for screening, consent and surveying. Once enrolled, respondents completed online surveys every 6 months via computer, tablet or smartphone. Numerous strategies were utilized to enhance retention and representativeness RESULTS: Results detail sample performance, representativeness and retention rates as well as device utilization trends for survey completion among youth and young adult respondents. Panel development efforts resulted in a large, nationally representative sample with high retention rates. This study is among the first to employ this hybrid ABS-to-online methodology to recruit and retain youth and young adults in a probability-based online cohort panel. The approach is particularly valuable for conducting research among younger populations as it capitalizes on their increasing access to and comfort with digital communication. We discuss challenges and opportunities of panel recruitment and retention methods in an effort to provide valuable information for tobacco control researchers seeking to obtain representative, population-based samples of youth and young adults in the U.S. as well as across the globe. © Article author(s) (or their employer

To examine the environmental pollution associated with e-waste recycling activities, the concentrations of organohologenated pollutants (OHPs), i.e., short- and medium-chain chlorinated paraffins (SCCPs and MCCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and several other halogenated flame retardants (OHFRs), were investigated in surface particulates from the workshop floors of four major e-waste recycling sites (Taizhou, Guiyu, Dali and Qingyuan) in China. The mean levels of SCCPs, MCCPs, PCBs, PBDEs and OHFRs in surface particulates ranged from 30,000–61,000, 170,000–890,000, 2700–27,000, 52,000–240,000, and 62,000–140,000 ng/g dry weight (dw), respectively. OHFRs, including decabromodiphenyl ethane, dechlorane plus, 1,2-bis(2,4,6-tribromophenoxy)ethane, tetrabromobisphenol A, hexabromocyclododecanes, polybrominated biphenyls, hexabromobenzene, pentabromotoluene, and pentabromoethylbenzene, were frequently (> 50% detection frequency) detected in surface particulates with mean concentration ranges of 39,000–63,000, 310–2700, 98–16,000, 21,000–56,000, 55–5700, 1700–27,000, 42–1600, 3.2–220, and 5.8–12 ng/g dw, respectively. The composition of OHPs varied depend on the e-waste items processing in different regions. Guiyu and Dali were typical sites contaminated by halogenated flame retardants (HFRs) and CPs, respectively, while Qingyuan, and Taizhou were representative PCB-polluted regions.

Full Text Available The analysis of natural phenomena applied to architectural planning and design is facing the most fascinating and elusive of the four dimensions through which man attempts to define life within the universe: time. We all know what time is, said St. Augustine, but nobody knows how to describe it. Within architectural projects and representations, time rarely appears in explicit form. This paper presents the results of a research conducted by students of NABA and of the Polytechnic of Milan with the purpose of representing time considered as a key element within architectural projects. Student investigated new approaches and methodologies to represent time using the two-dimensional support of a sheet of paper.

Background Israeli citizens have been exposed to intense and ongoing terrorism since September 2000. We previously studied the mental health impact of terrorism on the Israeli population (Bleich et al., 2002), however the long-term impact of ongoing terrorism has not yet been examined. The present study evaluated the psychological sequelae of 44 months of terrorism in Israel, and sought to identify factors that may contribute to vulnerability and resilience. Methods This was a telephone survey using strata sampling of 828 households, which reached a representative sample of 702 adult Israeli residents (84.8% contact rate). In total, 501 people (60.5%) agreed to participate. The methodology was similar to that of our previous study. Exposure to terrorism and other traumatic events, number of traumatic stress-related symptoms (TSRS), percentage of respondents with symptom criteria for post-traumatic stress disorder (PTSD), traumatic stress (TS) resiliency and feelings of depression, anxiety, optimism, sense of safety, and help-seeking were the main outcome measures. Results In total, 56 participants (11.2%) were directly exposed to a terrorist incident, and 101 (20.2%) had family members or friends exposed. Respondents reported a mean ± SD of 5.0 ± 4.5 TSRS; 45 (9%) met symptom criteria for PTSD; and 72 (14.4%) were TS-resilient. There were 147 participants (29.5%) who felt depressed, 50 (10.4%) felt anxious, and almost half (235; 47%) felt life-threatening danger; 48 (9.7%) felt the need for professional help. Women and people of Arab ethnicity had more TSRS, more PTSD, and less TS resiliency. Injury following a life-threatening experience, a major stressful life event, and a major loss of income were associated with PTSD. Immigrant status, lower education, low sense of safety, low sense of social support, high societal distress, and injury following life-threatening experiences were associated with TSRS. TSRS did not increase with exposure severity. This study

ESR teleradiology survey: results.

Science.gov (United States)

2016-08-01

With recent developments of teleradiology technology and services, it has become necessary to better evaluate its extent and use among different countries in Europe. With this goal in mind, the ESR launched two specific surveys intended to gather the current state of adoption and implementation of teleradiology in clinical practice. A special focus on differentiating between insourcing teleradiology services among partners of the same organisation and outsourcing to external services was an essential part of the design of these surveys. The first survey was addressed to 44 national societies of different countries in Europe, while the second survey was intended for all practicing radiologist ESR members. While the results of these surveys reported here may provide a wealth of information to better understand the trends in adoption of teleradiology in Europe, they only represent a snapshot at a certain point in time. The rapid development of telecommunication tools as well as a fundamental change in practice and healthcare economics will certainly influence these observations in the upcoming years. These data, however, will provide objective and relevant parameters for supporting the efforts of experts and policy makers in promoting appropriate criteria and guidelines for adequate use of teleradiology in clinical practice. Main Messages • Understand concepts and challenges of teleradiology • Provide insight into current trends and solutions for teleradiology • Compare differences in teleradiolgy strategies between countries in Europe • Establish a reference on statistical data of usage of teleradiology in Europe.

The values and distribution of the radioelements e U, e Th, % K and Ur units in the surface geological formations of the west and south sectors of Syrian region, were estimated using carbone gamma ray spectrometric survey. The radiometric maps were prepared, as well as, many geological profiles, cross sections studied in different locations and geochemical samples were analyzed by laboratory gamma ray spectrometry and by x-ray diffractometry, the results of the all sets were compared. In general, the survey shows, low radioelement concentrations in the area, especially on basic rocks (Jabal Al-arab, Hawran) south Syria, and on ultra basic rocks (ophiolitic complex) north-west Syria, but there are some separate anomalous spots were connected with phosphate rocks, detected on cretaceous and Palaeogene age. Some times we noticed high radioelement concentrations haloes associated with fractured zones were already arise from secondary uranium mineralization, as a result of solutions movement through fissures in carbonatic and/or chalk like limestone rocks. finally, the obtained concentrations, represent a background values which has no significant importance for uranium exploration point of view.

Full Text Available The article described the study of the relevance of the role and place of religious contents among young people in the postconflict areas of the South of Russia, the rate of experiences of mythological fear had been explored with the help of the survey, as well as individual psychological characteristics of subjects had been studied by methods of  Eysenck, Schmieschek, J. Rotter and Taylor. Those representatives of the surveyed youth sample experiencing a high level of mythological fear could fall into the danger zone of initiation in the group of non-traditional religious sects, as well as come under extremists’ influence, since manip-ulation of consciousness and human behavior, depending on individual psychological characteristics and by using of mythological content, such as fear of possession by jinni, is most effective. The study was attended by representatives of Islam at the age of 19-21, divided by gender: 100 young men and 100 girls. The study was aimed at identifying indi-vidual personality characteristics of temperament, character accentuations, locus of control, the level of personal anxiety and the results of a content analysis of the survey done by the author of the article were identified in accordance with five scales. Results of the study revealed that about 80% of subjects experiencing a high level of mythological fears had the same peculiar correlation indices. In connection with the results of research, we had worked out and suggested a complex of psycho-pedagogical support consisting of four modules for the purpose of education, preventive and corrective activities with young people experiencing a high level of mythological fear (fear of possession by jinni.
