    It is suggested that the energy difference between the Gamow-Teller and Fermi resonances is given, in units of MeV, by E sub(GT) - E sub(F) = 26A sup(-1/3) - 18.5 (N-Z)/A. The consequences of this result on the strenght of the spin and isopin dependent residual interaction, as well as on the effective axial-vector coupling constant, are discussed. (Author) [pt

    Full Text Available The total Gamow-Teller strengths and their energy distributions for 96Zr, 96Sr, 54Ca, 28O, 24C and 14C have been obtained within the framework of Random Phase Approximation (RPA. The effective interaction potential has been described by considering the commutativity of the Gamow-Teller operator with the central part of the nuclear Hamiltonian.

    A temperature dependence of collective nuclear excitations (giant resonances (GR) in particular) is a subject of theoretical and experimental investigations for many years. One of the reasons of this interest is that the GR properties at finite temperatures are quite important in understanding various astrophysical processes. For example, electron or neutrino capture on nuclei plays an essential role in the early presupernova collapse. In that context, it is important to know the dependence of the charge-exchange and/or magnetic resonance strength distribution from stellar media temperature. To study the problem, we apply the formalism based on the quasiparticle phonon model extended to finite temperature using the thermo field dynamics. Following the TFD prescriptions we have constructed a microscopic thermal Hamiltonian which describes collective vibrations in a hot nucleus. In this approach, the fragmentation of the giant vibrations at T≠0 is due to the coupling with thermal two-phonon configurations. The calculations are performed for selected nuclei from the Fe region. The Gamow-Teller strength distributions are calculated within the thermal RPA at different temperatures. Then they are used to study a temperature dependence of -decay rates for these nuclei in stellar media.

    Some aspects of the importance of neutrino-induced reactions on nuclei within supernova physics are discussed. It is argued that important constraints on the experimentally unknown cross sections can be obtained from experimental studies of the nuclear response in selected cases. Examples are neutral-current induced reactions on fp-shell nuclei extracted from high-resolution inelastic electron scattering data providing the M1 strength distributions and the production of the exotic heavy, odd-odd nuclei 138La and 180Ta through charged-current reactions dominated by Gamow-Teller transitions. The Gamow-Teller strength can deduced from the (3He,t) charge-exchange reaction at zero degree

    An analysis is made of the recent β+ decay measurements of Garcia et al., in order to see whether the 1981 37 Cl(p,n) 37 Ar measurements of Rapaport et al. are consistent with them. Garcia et al., were not able to determine the amount of Gamow-Teller strength in the isobaric analog state (IAS) or the Coulomb mixing of Fermi strength to a state near the IAS, and were forced to determine the amount of Gamow-Teller strength in the daughter 1371 keV state by making the branching ratios sum to unity. These uncertainties leave a range of possible values open which we investigate. We find that the experiments are consistent within part of this range. We also examine the effect of this range of allowed values on solar and supernova neutrino cross sections of 37 Cl and find weak dependence on the uncertainties described here. We discuss how this range can be narrowed so that the consistency of the two experiments can be conclusively tested

    It has been recognized for a number of years that certain spin-isospin components of the nucleon-nucleus effective interaction can be inferred from (p,n) reactions to states of known nuclear structure. For L = 0, S = 0 and L = 0, S = 1 transitions, the 0-degree (p,n) cross section can be related respectively to Fermi and Gamow-Teller beta decay matrix elements. If these transitions occur in the same nucleus, the ratio of isovector spin-flip to non-spin-flip effective interactions can be measured without regard for absolute normalization. The best reaction to measure this is /sup 14/C(p,n) which goes by a pure Gamow-Teller transition to the 1/sup /plus// state at 3.95 MeV in /sup 14/N, and Fermi transition to the 2.31 MeV 0/sup /plus// state. This work extends the ratio measurements made at lower energies (ref. 1, 2, 3) to 492 and 590 MeV. We also report on the /sup 13/C(p,n) reaction which goes by a pure GT transition to the 3.51 MeV 3/2/sup /minus// state in /sup 13/N, but by a mixed Fermi plus Gamow-Teller transition to the 1/2/sup /minus// ground state. 11 refs., 4 figs., 2 tabs.

    1999-10-01

    Recently it has been shown that pseudospin symmetry has its origins in a relativistic symmetry of the Dirac Hamiltonian[1]. Using this symmetry we relate single - nucleon relativistic magnetic moments of states in a pseudospin doublet to the relativistic magnetic dipole transitions between the states in the doublet, and we relate single - nucleon relativistic Gamow - Teller transitions within states in the doublet. We apply these relationships to the Gamow - Teller transitions from ^39Ca to its mirror nucleus ^39K [2] and to the systematics of forbidden magnetic dipole transitions. 1. J. N. Ginocchio and A.

    In the present work we perform a systematic shell-model study of Gamow-Teller transition-strength distributions in s d shell nuclei using ab initio effective interactions. The ab initio effective interactions are based on in-medium similarity renormalization-group and coupled-cluster effective interaction approaches. The aim of the present work is to test the predictive power of ab initio effective interactions by using the available experimental data of Gamow-Teller strength distributions in s d shell nuclei. We perform calculations for 20Ne→20F , 23Na→23Mg , 23Na→23Ne , 24Mg→24Na , 24Mg→24Al , 25Mg→25Al , 26Mg→26Na , 26Mg→26Al , 26Si→26Al , 27Al→27Si , 28Si→28P , 31P→31Si , and 32S→32P transitions. For comparison we also show the results obtained by using the phenomenological USDB Hamiltonian. The phenomenological USDB results of the Gamow-Teller (GT+ and GT-) strength distributions show reasonable agreements with the experimental data in comparison with the ab initio interactions. We also calculate the electron-capture reaction rates for 23Na(e-,ν )23Ne and 25Mg(e-,ν )25Na using ab initio and USDB interactions.

  12. Gamow-Teller strength functions from (→p,→p') scattering experiments

    1987-01-01

    We present here recent (→p, →'p) results from TRIUMF that are relevant to the determination of spin-flip isovector strength functions in nuclei. Distortion factors needed for the extraction of nuclear-structure information have been deduced from cross sections and analyzing powers in elastic scattering for several energies and targets. Nonrelativistic optical potentials obtained by folding effective nucleon (N)-nucleus interactions with nuclear densities are found to overpredict both elastic and reaction cross sections, whereas Dirac calculations that include Pauli blocking are in good agreement with the data. Spin observables (S nn and A y ) for the quasi-elastic region in 54 Fe(→p, →p) at 290 MeV provide some evidence for the reduction of the effective proton mass predicted in relativistic mean-field theories as a consequence of the attractive scalar field in the nuclear medium. The energy dependence of the effective N-nucleus interaction at small momentum transfers has been investigated using isoscalar and isovector 1 + states in 28 Si as probe states. We find that the cross sections for the isovector transitions are in good agreement with predictions for the dominant Vστ part of the Franey-Love interaction. Gamow-Teller (GT) strength functions have been obtained in 24 Mg and 54 Fe from measurements of both cross sections and spin-flip probabilities S nn . The spin-flip cross sections σS nn are particularly useful in heavier nuclei to discriminate against a continuous background of ΔS = 0 excitations. In the (s, d) shell where full shell-model wave functions are available, the GT quenching factors (g A eff / g A free ) 2 ≅ 0.7 are in good agreement with those from recent (p, n) and (n, p) experiments. We show that a state-by-state comparison of (p, p') and (e, e') results has the potential of identifying pionic current contributions in (e, e'). The GT quenching factors in 54 Fe are smaller than in the (s, d) shell probably because of severely

    Beta-decay studies of very proton-rich nuclides allow to investigate the phenomenon of quenching of Gamow-Teller transitions. A presentation of the experimental techniques is followed by the discussion of preliminray results of the measurements in comparison to shell-model calculations. A corresponding reinvestigation is discussed. A mass-separated 48 Mn beam was used from 12 C( 40 Ca,p3n) reactions. The 48 Mn decay spectroscopy was performed simultaneously in two beam lines of the mass separator. (G.P.) 13 refs.; 2 figs

    The tensor terms of the Skyrme effective interaction are included in the self-consistent Hartree-Fock plus Random Phase Approximation (HF-RPA) model. The Gamow-Teller (GT) strength function of 9 0Z r and 2 08P b are calculated with and without the tensor terms. The main peaks are moved downwards by about 2 MeV when including the tensor contribution. About 10% of the non-energy weighted sum rule is shifted to the excitation energy region above 30 MeV by the RPA tensor correlations. The contribution of the tensor terms to the energy weighted sum rule is given analytically, and compared to the outcome of RPA. A microscopic origin of the quenching of GT sum rule is discussed in relation with the coupling to giant spin-quadrupole excitations by the tensor interactions.(author)

    Gamow-Teller (GT) transitions in atomic nuclei are sensitive to both nuclear shell structure and effective residual interactions. The nuclear GT excitations were studied for the mass number A = 42, 46, 50, and 54 "f-shell" nuclei in ((3)He, t) charge-exchange reactions. In the (42)Ca → (42)Sc reaction, most of the GT strength is concentrated in the lowest excited state at 0.6 MeV, suggesting the existence of a low-energy GT phonon excitation. As A increases, a high-energy GT phonon excitation develops in the 6-11 MeV region. In the (54)Fe → (54)Co reaction, the high-energy GT phonon excitation mainly carries the GT strength. The existence of these two GT phonon excitations are attributed to the 2 fermionic degrees of freedom in nuclei.

    Full Text Available A finite rank separable approximation for the quasiparticle random phase approximation (QRPA with Skyrme interactions is applied to study properties of the Gamow-Teller (GT resonances in the neutron-rich Cd isotopes. This approximation enables one to reduce considerably the dimension of matrix that must be diagonalized to perform QRPA calculations in a very large configuration space. Our results from the SGII Skyrme interaction with the tensor interactions and the density-dependent zero-range pairing interaction show that the GT distribution is noticeably modified when the tensor correlations are taken into account. In particular, for 130Cd the dominant peak is moved 3.6 MeV downward and 10% of the GT distribution is shifted to the high excitation energy region near E=50MeV.

    Gamma radiation and delayed neutrons following the decay of 29 Na have been studied in singles and coincidence mode with mass-separated sources at the ISOLDE facility. Evidence for a first excited state in 29 Mg at 54.6 keV has been found, in good agreement with theoretical predictions. From the lifetime, deduced from γ-γ delayed coincidences with BaF 2 counters, a transition strength is found for the 55 keV (1/2 + )→ g.s. (3/2 + ) transition. A level scheme built on the new state at 55 keV and involving five new transitions has been established for bound levels in 29 Mg. The features of these levels are compared with predictions of shell-model calculations, with which they substantially agree. In the neutron time-of-flight spectra, high-energy neutron branches have been found in addition to the previously reported decays. The observed distribution of the Gamow-Teller transition strengths with excitation energy for particle-unbound levels in 29 Mg is found to be shifted upward by about 1 MeV relative to shell-model predictions

    β-decay half-lives set the time scale of the rapid neutron capture process, and are therefore essential for understanding the origin of heavy elements in the universe. The random-phase approximation (RPA) based on Skyrme energy density functionals is widely used to calculate the properties of Gamow-Teller (GT) transitions, which play a dominant role in β-decay half-lives. However, the RPA model has its limitations in reproducing the resonance width and often overestimates β-decay half-lives. To overcome these problems, effects beyond mean-field can be included on top of the RPA model. In particular, this can be obtained by taking into account the particle-vibration coupling (PVC). Within the RPA+PVC model, we successfully reproduce the experimental GT resonance width and β-decay half-lives in magic nuclei. We then extend the formalism to superfluid nuclei and apply it to the GT resonance in 120Sn, obtaining a good reproduction of the experimental strength distribution. The effect of isoscalar pairing is also discussed.

    2018-04-01

    A shell-model method for calculating Gamow-Teller (GT) transition rates in heavy deformed odd-mass nuclei is presented. The method is developed within the framework of the projected shell model. To implement the computation requirement when many multi-quasiparticle configurations are included in the basis, a numerical advancement based on the Pfaffian formula is introduced. With this new many-body technique, it becomes feasible to perform state-by-state calculations for the GT nuclear matrix elements of β -decay and electron-capture processes, including those at high excitation energies in heavy nuclei which are usually deformed. The first results, β- decays of the well-deformed A =153 neutron-rich nuclei, are shown as the example. The known log(f t ) data corresponding to the B (GT- ) decay rates of the ground state of 153Nd to the low-lying states of 153Pm are well described. It is further shown that the B (GT) distributions can have a strong dependence on the detailed microscopic structure of relevant states of both the parent and daughter nuclei.

    We study the double Gamow-Teller (DGT) strength distribution of 48Ca with state-of-the-art large-scale nuclear shell model calculations. Our analysis shows that the centroid energy of the DGT giant resonance depends mostly on the isovector pairing interaction, while the resonance width is more sensitive to isoscalar pairing. Pairing correlations are also key in neutrinoless β β (0 ν β β ) decay. We find a simple relation between the centroid energy of the 48Ca DGT giant resonance and the 0 ν β β decay nuclear matrix element. More generally, we observe a very good linear correlation between the DGT transition to the ground state of the final nucleus and the 0 ν β β decay matrix element. The correlation, which originates on the dominant short-range character of both transitions, extends to heavier systems including several β β emitters and also holds in energy-density functional results. Our findings suggest that DGT experiments can be a very valuable tool to obtain information on the value of 0 ν β β decay nuclear matrix elements.

    We propose a schematic model of nucleons moving in spin-orbit partner levels, j = l ±1/2, to explain Gamow-Teller and two-nucleon transfer data in N = Z nuclei above 40Ca. Use of the LS coupling scheme provides a more transparent approach to interpret the structure and reaction data. We apply the model to the analysis of charge-exchange, 42Ca(3He,t)42Sc, and np-transfer, 40Ca(3He,p)42Sc, reactions data to define the elementary modes of excitation in terms of both isovector and isoscalar pairs, whose properties can be determined by adjusting the parameters of the model (spin-orbit splitting, isovector pairing strength and quadrupole matrix element) to the available data. The overall agreement with experiment suggests that the approach captures the main physics ingredients and provides the basis for a boson approximation that can be extended to heavier nuclei. Our analysis also reveals that the SU(4)-symmetry limit is not realized in 42Sc.

    We have performed large-scale shell model calculations of the Gamow-Teller strength distributions in N{proportional_to}Z pf-shell nuclei. These calculations were motivated by the experimental attempts to measure the low-lying GT strength for the even-even N=Z+2 or N=Z-2 nuclei {sup 46}Ti, {sup 50}Cr, {sup 54}Fe and {sup 62}Ge, where a sizable low-energy GT strength could be interpreted as reminiscence of SU(4) symmetry; in the limit of exact SU(4) symmetry the GT{sub -} strength would be concentrated in a single transition to the lowest T=0, J=1{sup +} state in the daughter. We confirm that the SU(4) symmetry is strongly broken by the spin-orbit interaction and by increasing neutron excess. (orig.)

    Nuclei with A {approx} 70 along the N=Z line are known to be the scene of phenomena closely related to the nuclear deformation and are of particular interest since theoretical mean field calculations predict that a large part of the Gamow-Teller resonance might be located below the ground state of the mother nucleus and then be accessible through {beta}-decay studies. These results have shown the effect of the shape of the ground state on the intensity of the Gamow-Teller strength. Thus, the experimental determination, through {delta}-decay, of the Gamow-Teller strength distribution and the comparison to the theoretical predictions allow to pin down the quadrupolar deformation parameter of the ground state of the parent nucleus. In order to study the neutron deficient isotopes of krypton (A=72,73,74,75) and strontium (A=76,77,78) and to establish the {beta}-strength on the full energy range, a new total absorption spectrometer (TAgS) has been built in the frame of an international collaboration and installed at the (SOLDE/CERN mass separator. For the data analysis, the response function R of the spectrometer has been calculated by means of Monte-Carlo simulations, based on the GEANT4 code, and of a statistical description of the level scheme in the daughter nucleus. The {beta}-feeding distribution has been obtained from experimental spectra through a method based on Bayes theorem and then converted into Gamow-Teller strength. The results coming from the {sup 74}Kr decay analysis allow to describe the ground state of such a nucleus as the coexistence of an oblate shape and of a prolate shape. In the case of {sup 76}Sr, the experimental Gamow-Teller strength distribution strongly indicates a prolate deformation. (author)

    We have studied the Gamow-Teller (GT) transitions from N =Z +2 neighbors to N =Z odd-odd nuclei in the p -shell region by using isospin-projected and β γ -constraint antisymmetrized molecular dynamics combined with the generator coordinate method. The calculated GT transition strengths from 0+1 states to 1+0 states such as 6He(01+1 ) →6Li(11+0 ) , 10Be(01+1 ) →10B(11+0 ) , and 14C(01+1 ) →14N(12+0 ) exhaust more than 50% of the sum rule. These N =Z +2 initial states and N =Z odd-odd final states are found to dominantly have S =0 ,T =1 n n pairs and S =1 ,T =0 p n pairs, respectively. Based on the two-nucleon (N N ) pair picture, we can understand the concentration of the GT strengths as the spin-isospin-flip transition n n (S =0 ,T =1 )→p n (S =1 ,T =0 ) in L S coupling. The GT transition can be a good probe to identify the spin-isospin partner states with n n pairs and p n pairs of N =Z +2 and N =Z odd-odd nuclei, respectively.

    Given the importance of Gamow-Teller (GT) transitions in nuclear structure and astrophysical nuclear processes, we have studied Tz=+3/2→+1/2, GT transitions starting from the 47Ti nucleus in the (3He,t) charge-exchange reaction at 0∘ and at an intermediate incident energy of 140 MeV/nucleon. The experiments were carried out at the Research Center for Nuclear Physics (RCNP), Osaka, using the high-resolution facility with a high-dispersion beam line and the Grand-Raiden spectrometer. With an energy resolution of 20 keV, individual GT transitions were observed and GT strength was derived for each state populated up to an excitation energy (Ex) of 12.5 MeV. The GT strength was widely distributed from low excitation energy up to 12.5 MeV, where we had to stop the analysis because of the high level density. The distribution of the GT strengths was compared with the results of shell model calculations using the GXPF1 interaction. The calculations could reproduce the experimental GT distributions well. The GT transitions from the ground state of 47Ti and the M1 transitions from the isobaric analog state in 47V to the same low-lying states in 47V are analogous. It was found that the ratios of GT transition strengths to the ground state, the 0.088-MeV state, and the 0.146-MeV state are similar to the ratios of the strengths of the analogous M1 transitions from the isobaric analog state (IAS) to these states. The measured distribution of the GT strengths was also compared with those starting from the Tz=+3/2 nucleus 41K to the Tz=+1/2 nucleus 41Ca.

    In this paper we present theoretical results on the dipole response in the proton spin-saturated {sup 90-94}Zr isotopes. The electric and magnetic dipole excitations are obtained in Hartree-Fock-Bogolyubov plus Quasi-particle Random Phase Approximation (QRPA) calculations performed with the D1M Gogny force. A pnQRPA charge exchange code is used to study the Gamow-Teller response. The results on the pygmy, the giant dipole resonances as well as those on the magnetic nuclear spin-flip excitation and the Gamow-Teller transitions are compared with available experimental or theoretical information. In our approach, the proton pairing plays a role in the phonon excitations, in particular in the M1 nuclear spin-flip resonance. (orig.)

    The magnetic dipole moments of states in mirror pairs of the sd-shell nuclei and the strengths of the Gamow-Teller beta decays which connect them are compared with predictions based on mixed-configuration shell-model wave functions. From this analysis we extract the average effective values of the single-particle matrix elements of the l, s, and [Y/sup( 2 )xs]/sup( 1 ) components of the M1 and Gamow-Teller operators acting on nucleons in the 0d/sub 5/2/, 1s/sub 1/2/, and 0d/sub 3/2/ orbits. These results are compared with the recent calculations by Towner and Khanna of the corrections to the free-nucleon values of these matrix elements which arise from the effects of isobar currents, mesonic-exchange currents, and mixing with configurations outside the sd shell

    The deformed proton-neutron quasiparticle random phase approximation (QRPA) has been developed and applied to evaluate Gamow-Teller (GT) transition strength distributions, including high-lying excited states. The data of high-lying excited states are recently available beyond one or two nucleon threshold by charge exchange reactions using hundreds of MeV projectiles. Our calculations started with single-particle states calculated using a deformed, axially symmetric Woods-Saxon potential. The neutron-neutron and proton-proton pairing correlations are explicitly taken into account at the deformed Bardeen-Cooper-Schriffer theory. Additionally, the ground state correlations and two-particle and two-hole mixing states were included in the deformed QRPA. In this work, we used a realistic two-body interaction, given by the Brueckner G-matrix based on the CD Bonn potential to reduce the ambiguity on the nucleon-nucleon interactions inside nuclei. We applied our formalism to the GT transition strengths for 76Ge, 76,82Se, and 90,92Zr, and compared the results with the available experimental data. The GT strength distributions were sensitive to the deformation parameter as well as its sign, i.e., oblate or prolate. The Ikeda sum rule, which is usually thought to be satisfied under the one-body current approximation, regardless of nucleon models, was used to test our numerical calculations and shown to be satisfied without introducing the quenching factor, if high-lying GT excited states were properly taken into account. Most of the GT strength distributions of the nuclei considered in this work have the high-lying GT excited states beyond one-nucleon threshold, which are shown to be consistent with the available experimental data.

    Under the assumption that isospin T is a good quantum number, isobaric analog states and various analogous transitions are expected in isobars with mass number A . The strengths of Tz =±3/2→±1/2 analogous Gamow-Teller (GT) transitions and analogous M1 transitions within the A=41 isobar quartet are compared in detail. The Tz =+3/2→+1/2 GT transitions from the Jπ = 3/2+ ground state of 41K leading to excited Jπ = 1/2+ , 3/2+ , and 5/2+ states in 41Ca were measured using the ( 3He ,t) charge-exchange reaction. With a high energy resolution of 35 keV , many fragmented states were observed, and the GT strength distribution was determined up to 10 MeV excitation energy ( Ex ) . The main part of the strength was concentrated in the Ex =4 6 MeV region. A shell-model calculation could reproduce the concentration, but not so well details of the strength distribution. The obtained distribution was further compared with two results of 41Ti β decay studying the analogous Tz =-3/2→-1/2 GT strengths. They reported contradicting distributions. One-to-one correspondences of analogous transitions and analog states were assigned up to Ex =6 MeV in the comparison with one of these 41Ti β -decay results. Combining the spectroscopic information of the analog states in 41Ca and 41Sc , the most probable Jπ values were deduced for each pair of analog states. It was found that 5/2+ states carry the main part of the observed GT strength, while much less GT strength was carried by 1/2+ and 3/2+ states. The gross features of the GT strength distributions for each J were similar for the isospin analogous Tz =±3/2→±1/2 transitions, but the details were somewhat different. From the difference of the distributions, isospin-asymmetry matrix elements of ≈8 keV were deduced. The Coulomb displacement energy, which is sensitive to the configuration of states, showed a sudden increase of about 50 keV at the excitation energy of 3.8 MeV . The strengths of several M1 transitions to the

    Background: The atomic nucleus is a unique laboratory in which to study fundamental aspects of the electroweak interaction. This includes a question concerning in medium renormalization of the axial-vector current, which still lacks satisfactory explanation. Study of spin-isospin or Gamow-Teller (GT) response may provide valuable information on both the quenching of the axial-vector coupling constant as well as on nuclear structure and nuclear astrophysics. Purpose: We have performed a seminal calculation of the GT response by using the no-core configuration-interaction approach rooted in multireference density functional theory (DFT-NCCI). The model treats properly isospin and rotational symmetries and can be applied to calculate both the nuclear spectra and transition rates in atomic nuclei, irrespectively of their mass and particle-number parity. Methods: The DFT-NCCI calculation proceeds as follows: First, one builds a configuration space by computing relevant, for a given physical problem, (multi)particle-(multi)hole Slater determinants. Next, one applies the isospin and angular-momentum projections and performs the isospin and K mixing in order to construct a model space composed of linearly dependent states of good angular momentum. Eventually, one mixes the projected states by solving the Hill-Wheeler-Griffin equation. Results: The method is applied to compute the GT strength distribution in selected N ≈Z nuclei including the p -shell 8Li and 8Be nuclei and the s d -shell well-deformed nucleus 24Mg. In order to demonstrate a flexibility of the approach we present also a calculation of the superallowed GT β decay in doubly-magic spherical 100Sn and the low-spin spectrum in 100In. Conclusions: It is demonstrated that the DFT-NCCI model is capable of capturing the GT response satisfactorily well by using a relatively small configuration space, exhausting simultaneously the GT sum rule. The model, due to its flexibility and broad range of applicability, may

    The nuclear gross theory, originally formulated by Takahashi and Yamada (1969 Prog. Theor. Phys. 41 1470) for the β-decay, is applied to the electronic-neutrino nucleus reactions, employing a more realistic description of the energetics of the Gamow-Teller resonances. The model parameters are gauged from the most recent experimental data, both for β - -decay and electron capture, separately for even-even, even-odd, odd-odd and odd-even nuclei. The numerical estimates for neutrino-nucleus cross-sections agree fairly well with previous evaluations done within the framework of microscopic models. The formalism presented here can be extended to the heavy nuclei mass region, where weak processes are quite relevant, which is of astrophysical interest because of its applications in supernova explosive nucleosynthesis

    The retrofitting of scrubbers downstream of existing balanced draft boilers is often accomplished by the addition of induced draft (ID) booster fans. By creating a common plenum between the ID fans and the ID booster fans of two or more boiler-absorber trains, absorber module capacity may be shared among multiple boiler units. At Harrison Power Station, three (3) 4,900,000 lb/hour boilers (640 MWe Gross) will be linked through a common plenum. This sharing capability precludes the need to add standby module capacity, thereby saving capital dollars and keeping project critical path schedules, which typically run through absorber procurement and construction, to a minimum. Through damper placement in the ductwork cross connections, unitized boiler-absorber module operation or common plenum operation may be obtained, thus providing both operational flexibility and reliability. Additionally, open plenum operation allows the removal of an absorber unit from service, while keeping its associated boiler on line, thereby precluding 'cold starts' and maintaining overall unit availabilities. As either unitized or common plenum operation is possible with the cross connection, the furnace draft control systems of each boiler must be examined for varying load operation and trip conditions. This paper addresses the means by which to analyze such cross connection operational scenarios while maintaining compliance with furnace flame out safety guidelines, and will discuss the physical design considerations, ramifications and benefits of same, with select emphasis on what is being implemented at the Harrison Power Station

The ratio of L=0 isovector spinflip cross section and Gamow-Teller strength has been investigated at 200-450 MeV for several strong transitions of known B(GT) in p-shell nuclei. Isospin symmetry in N-nucleus reactions has been tested for Gamow-Teller transitions to isospin triads in A=6 and A=12 nuclei. The prospects of identifying orbital and meson exchange current contributions in M1 transitions from a state-by-state comparison of M1 and Gamow-Teller strength in sd shell nuclei are discussed. Finally we describe a test of the Gamow-Teller sum rule in 54 Fe where both S - and S + strength are substantial and have been extracted from a multipole decomposition of (p,n) and (n,p) angular distributions

    Bedriddenness and immobilization of patients at an intensive care unit may result in muscle atrophy and devaluation in quality of life. The exact effect of immobilization on intensive care unit patients is not known. The aim of this study was to investigate the magnitude and time course of muscle cross-section decrease in acute critically ill patients admitted to the intensive care unit. An observational pilot study was performed in intensive care unit patients. Data of bilateral ultrasound muscle cross-section measurements of the knee extensors and the elbow flexors were collected. Thirty-four intensive care unit patients were included in this study; data are presented from 14 patients who were measured at least three times. Repeated measures analysis of variance shows a significant decrease in muscle cross-section over time (F1,13 = 80.40, P ≤ 0.001).The decrease in muscle cross-section of the arms was significantly higher (F1,13 = 5.38, P = 0.037) than the decrease of the legs. Four weeks after intensive care unit admission, the muscle cross-section decrease had not reached an asymptote yet. The muscle cross-section decrease in bedridden intensive care unit patients is significant for a time of 2 to 4 weeks. The decrease in muscle cross-section of the arms is greater than the decrease of the legs.

    Nursing unit is the micro-organization in the hospital health care system in which integrated patient care is provided. Nursing units of different types serve patients with distinct care goals, clinical tasks, and social structures and norms. However, empirical evidence is sparse on unit type differences in quality of care and its relation with nurse work environment. Nurse work environment has been found as an important nursing factor predicting nurse and patient outcomes. To examine the unit type differences in nurse-reported quality of care, and to identify the association between unit work environment and quality of care by unit types. This is a cross-sectional study using nurse survey data (2012) from US hospitals nationwide. The nurse survey collected data on quality of care, nurse work environment, and other work related information from staff nurses working in units of various types. Unit types were systematically classified across hospitals. The unit of analysis was the nursing unit, and the final sample included 7677 units of 14 unit types from 577 hospitals in 49 states in the US. Multilevel regressions were used to assess the relationship between nurse work environment and quality of care across and by unit types. On average, units had 58% of the nurses reporting excellent quality of care and 40% of the nurses reporting improved quality of care over the past year. Unit quality of care varied by unit types, from 43% of the nurses in adult medical units to 73% of the nurses in interventional units rating overall quality of care on unit as excellent, and from 35% of the nurses in adult critical care units to 44% of the nurses in adult medical units and medical-surgical combined units reporting improved quality of care. Estimates from regressions indicated that better unit work environments were associated with higher quality of care when controlling various hospital and unit covariates; and this association persisted among units of different types.

    It has been pointed out by many documents that a phase gradient metasurface with wideband characteristics can be designed by the unit with a low-quality factor ( Q value). In this paper, a cross-shaped unit with a low-quality factor Q is proposed. By changing the variable parameters of the unit, it is found that the reflection phase of the unit can achieve a stable distribution of phase gradient in the frequency range of 8.0-20.0 GHz. we analyze variation of the electromagnetic field distribution on the unit with frequency and find that the size along electrical field polarization of electromagnetic field distribution area changes with frequency. Based on our design, effective size of electromagnetic field distribution area keeps meeting the subwavelength condition, thus stable phase distribution is gained across broadened bandwidth. It is found by the analysis of the phase gradient metasurface composed of seven units that the metasurface can exhibit anomalous reflection in the wide frequency band of 8.0-20.0 GHz, and the efficiency of abnormal reflection is higher in the range of 10.0-18.0 GHz. The error between the simulation results of abnormal reflection angle and the theoretical result is only - 1.5° to 0.5° after the work of comparison. Therefore, the metasurface designed by the new cross-shaped unit has a good control on the deflection direction of the reflected wave, and shows obvious advantages in widening the bandwidth.

Two cross-sectional surveys were performed, in 2008/2009 (time 1) and 2012/2013 (time 2). During a period of 0-3 years after time 1, three of six hospitals merged their general and medical intensive care units (restructured). The other hospitals maintained their structure of the intensive care units (not restructured). Intensive care units in hospitals at one Norwegian hospital trust. The safety culture was measured with Hospital Survey on Patient Safety Culture. At times 1 and 2, 217/302 (72%) and 145/289 (50%) registered nurses participated. Restructuring was negatively associated with change in the safety culture, in particular, the dimensions of the safety culture within the unit level. The dimensions most vulnerable for restructuring were manager expectations and actions promoting safety, teamwork within hospital units and staffing. In this study, the restructuring of intensive care units was associated with a negative impact on the safety culture. When restructuring, the management should be particularly aware of changes in the safety culture dimensions manager expectations and actions promoting safety, teamwork within hospital units and staffing.

    Czajkowski, C.J.

    1987-01-01

    A metallurgical investigation was performed on a sample of cracked ring header cross material from the Grand Gulf Unit No. 1 Nuclear Power Station. The cracks were located in a 6-7 in (15-17.5 cm) width band running circumferentially below the cross to cap weld with a similar band above the cross to discharger pipe weld. The indications were up to 19 mm in length and 6.0 mm in depth. This particular sample was cut from a cross which had not seen actual service but which had been used to qualify the induction heating stress improvement (IHSI) technique for the Grand Gulf units. The base material was SA 182 material manufactured to SA 403-type WP 304 stainless steel. The investigation consisted of visual/dye penetrant examination, chemical analysis, hardness testing, optical microscopy, scanning electron microscopy and energy dispersive spectroscopy. The evaluated cracks were intergranular and initiated on the forging's exterior surface. The grain size of the material was larger than ASTM 00 and no definitive corrosive species were found by Energy Dispersive Spectroscopy (EDS). The cracking is considered to be the result of the forging having been overheated/burned during manufacture. (author)

  13. Initiatives of cross-border regional planning in Matamoros-Brownsville (Mexico-United States

    2016-03-01

    Full Text Available Cross-border regional planning is a recent phenomenon, which its first initiatives date back to 1960s. Currently some experiences have been conducted, most of them in Europe. The weak development of this phenomenon lies on the obstacles and limitations that it has to deal with. Those obstacles derive from the asymmetries between the political and administrative systems, urban and spatial policies, land planning and land uses, etc. on each side of an international border. In a great extent, cross-border planning has been theoretically approached from an institutional construction perspective. However, in this research it has been adopted the symbolic regional construction perspective that allows to analyze cross-border regional planning through spatial imaginaries. In this sense, crossborder planning is understood as a result of the interaction between regional actors and the social constructed values and meanings (geographical, cultural, social, economic, historical, etc. given to border and cross-border regions. This investigation pursues, in first place, to determine the spatial imaginaries on which cross-border planning is constructed and, at the same time, the spatial imaginaries that cross-border planning reproduces; in second place, to determine in which way cross-border planning contributes to deactivate the border (deborder or, on the contrary, to reproduce and reinforce the spatial differentiation process (the process by which two contiguous national or bordered spaces build spatial discontinuities as a way to distinguish of each other. To achieve these objectives, it has been conducted a content analysis based on the documentation of the spatial and urban planning and of the cross-border initiatives from a case study area; a direct observation of an ongoing cross-border initiative; and interviews to key informants (planning agencies and other organizations related to cross-border initiatives.

    Extensively drug-resistant Acinetobacter baumannii (XDRAB) is a great threat in intensive care units (ICUs). The aim of this study was to describe an XDRAB outbreak which was cross-transmitted in the ICU and respiratory intensive care unit (RICU) in a tertiary care hospital from January-March 2013. Patient and environmental surveillances were performed. Isolates were tested for antimicrobial susceptibility. Genotypes were analyzed by multilocus sequence typing (MLST). A series of enhanced strategies were implemented to control the outbreak. A total of 11 patients were infected by XDRAB strains during this outbreak. Three patients in the ICU were found positive for XDRAB at the onset of the outbreak. Thereafter, infections were detected in 6 patients in the RICU, followed by reappearance of this strain in the ICU in 2 patients. All A baumannii strains isolated from patients and the environment were extensively drug resistant. MLST revealed them as ST368. After 3 rounds of environmental screening and cleaning, the laminar flow system connecting the ICU and RICU was found as the source of transmission. Successful control of this outbreak was achieved through multifaceted intervention measures. This study suggested the importance of thorough surveillance and disinfection of the environment, including concealed devices, in preventing the transmission of an outbreak.

    Full Text Available The article considers the problems associated with the analysis and selection of basic linguacultural units that are necessary for a more effective cross-cultural communication. To make the process of dialogue between different cultures and languages more appropriate and productive, it is necessary to possess certain knowledge, skills, which are acquired by man in the process of learning. Important in our opinion in this area are the mastery means which will prepare the person to communicate in a different communicative space. Such means, in our opinion, are the basic linguacultural units, which are considered as carriers of information and expression of cultural identity. They inform choice contributes to a worldview, understanding linguacultural picture of the world community. The basis of selection of linguistic units on the following criteria: the information content, functionality, sufficiency, cultural identity, realism, pivotal importance to the basic sense, social and cultural significance. Application of the proposed criteria allowing more appropriate to make the selection of the material and linguacultural integral components of the scope of cross-cultural interaction, which are characterized by their relevant material necessary for an adequate understanding of the processes occurring in different communicative space.

    Full Text Available A cross-national study of young adult sexual minorities was conducted in order to explore the associations between sexual orientation and measures of depression, suicidality, and substance use. Two nationally representative data sets were explored from the United States (N = 14,335 and Norway (N = 2423. Results indicated that sexual minorities experienced multiple health disparities (depression, suicidality, and substance use compared to their heterosexual counterparts. We found similar patterns of depression, suicidality, and substance use for sexual minorities in both the United States and Norway. The highest odds of substance use were among heterosexual-identified Norwegian youth who reported same-sex sexual activity, and the highest odds of suicidality were found for bisexual young adults in Norway. These findings have implications for how we consider culture and social policy as barriers and/or opportunities for sexual minorities.

    2004-01-01

    Objectives To describe the multicentre clinical databases that exist in the United Kingdom, to report on their quality, to explore which organisational and managerial features are associated with high quality, and to make recommendations for improvements. Design Cross sectional survey, with interviews with database custodians and search of electronic bibliographic database (PubMed). Studies reviewed 105 clinical databases across the United Kingdom. Results Clinical databases existed in all areas of health care, but their distribution was uneven—cancer and surgery were better covered than mental health and obstetrics. They varied greatly in age, size, growth rate, and geographical areas covered. Their scope (and thus their potential uses) and the quality of the data collected also varied. The latter was not associated with any organisational characteristics. Despite impressive achievements, many faced substantial financial uncertainty. Considerable scope existed for improvements: greater use of nationally approved codes; more support from relevant professional organisations; greater involvement by nurses, allied health professionals, managers, and laypeople in database management teams; and more attention to data security and ensuring patient confidentiality. With some notable exceptions, the audit and research potential of most databases had not been realised: half the databases had each produced only four or fewer peer reviewed research articles. Conclusions At least one clinical database support unit is needed in the United Kingdom to provide assistance in organisation and management, information technology, epidemiology, and statistics. Without such an initiative, the variable picture of databases reported here is likely to persist and their potential not be realised. PMID:15205292

    As has been the case with other types of medical tourism, the phenomenon of cross border fertility care ("CBFC") has sparked concern about the lack of global or even national harmonization in the regulation of the fertility industry. The diversity of laws around the globe leads would-be parents to forum shop for a welcoming place to make babies. Focusing specifically on the phenomenon of travel to the United States, this Article takes up the question of whether there should be any legal barriers to those who come to the United States seeking CBFC. In part, CBFC suffers from the same general concerns raised about the use of fertility treatment in general, but it is possible to imagine a subset of arguments that would lead to forbidding or at least discouraging people from coming to the United States for CBFC, either as a matter of law or policy. This paper stands in opposition to any such effort and contemplates the moral and ethical concerns about CBFC and how, and if, those concerns warrant expression in law. Part I describes the conditions that lead some couples and individuals to leave their home countries to access fertility treatments abroad and details why the United States, with its comparatively liberal regulation of ART, has become a popular CBFC destination for travelers from around the world. Part II offers and refutes arguments supporting greater domestic control over those who seek to satisfy their desires for CBFC in the United States by reasserting the importance of the right of procreation while also noting appropriate concerns about justice and equality in the market for babies. Part III continues the exploration of justice by investigating the question of international cooperation in legislating against perceived wrongs. This Part concludes that consistent legislation across borders is appropriate where there is consensus about the wrong of an act, but it is unnecessary and inappropriate where there remain cultural conflicts about certain

    Critical care patients benefit from the attention of nursing personnel with a high competence level. The aim of the study was to describe and evaluate the self-assessed basic competence of intensive care unit nurses and related factors. A cross-sectional survey design was used. A basic competence scale (Intensive and Critical Care Nursing Competence Scale version 1, Likert scale 1-5, 1 = poor and 5 = excellent) was employed among Finnish intensive care unit nurses (n = 431). Intensive care unit nurses' self-assessed basic competence was good (mean 4.19, SD 0.40). The attitude and value base of basic competence was excellent whereas experience base was the poorest compared to the knowledge base and skill base of intensive and critical care nursing. The strongest factor explaining nurses' basic competence was their experience of autonomy in nursing care (F value 60.85, β 0.11, SE 0.01, and P ≤ 0.0001). Clinical competence was self-rated as good. Nurses gave their highest competence self-ratings for ICU patient care according to the principles of nursing care. The ICU nurses also self-rated their professional competence as good. Collaboration was self-rated as the best competence. In basic and continuing education and professional self-development discussions it is meaningful to consider and find solutions for how to improve nurses' experienced autonomy in nursing.

    Reducing the complexity of cross-linked polymer networks by preserving their main macroscale properties is key to understanding them, and a crucial issue is to relate individual properties of the polymer constituents to those of the reduced network. Here we study polymer networks in a good solvent, by considering star polymers as their unit elements, and first quantify the interaction between their centers of masses. We then reduce the complexity of a network by replacing sets of its bridged star polymers by equivalent effective soft particles with dense cores. Our coarse graining allows us to approximate complex polymer networks by much simpler ones, keeping their relevant mechanical properties, as illustrated in computer experiments.

  5. A Cross-cultural Comparison of Objectivity in Childhood Games: Iran and the United States.

    2011-07-01

    Games have been introduced as a means for studying cross-cultural differences and societies. This paper presents a case study in analogous games played by children in two different countries with two different cultures - Iran and the United States. Four examples are presented to demonstrate that games played by Iranian children are subject to less objectivity in their rules. Therefore, nonobjectivity may be a phenomenon that has roots in the society and the many differences between the two societies may very well be the results of this fundamental difference. If the presence of objectivity in childhood game rules could be, in actuality, indicative of objectivity in social and civil interactions in the everyday lives of the people, the direction of causality remains to be established. In other words, it remains unclear whether the games influence the culture or are influenced by the mandates of the society.

    Integral field spectroscopy represents a powerful technique for the detection and characterization of extrasolar planets through high-contrast imaging since it allows us to obtain simultaneously a large number of monochromatic images. These can be used to calibrate and then to reduce the impact of speckles, once their chromatic dependence is taken into account. The main concern in designing integral field spectrographs for high-contrast imaging is the impact of the diffraction effects and the noncommon path aberrations together with an efficient use of the detector pixels. We focus our attention on integral field spectrographs based on lenslet arrays, discussing the main features of these designs: the conditions of appropriate spatial and spectral sampling of the resulting spectrograph's slit functions and their related cross-talk terms when the system works at the diffraction limit. We present a new scheme for the integral field unit based on a dual-lenslet device (BIGRE), that solves some of the problems related to the classical Traitement Integral des Galaxies par l'Etude de leurs Rays (TIGER) design when used for such applications. We show that BIGRE provides much lower cross-talk signals than TIGER, allowing a more efficient use of the detector pixels and a considerable saving of the overall cost of a lenslet-based integral field spectrograph.

  8. Similarity of Cross-Sectional Characteristics of Costal Plain Streams of the Southeastern United States

    The Coastal Plain physiographic region of the southeastern United States encompasses over 1.2 million km2. Analysis of data from six separate geomorphic studies conducted in five of the 19 states having a Coastal Plain region suggests that streams of the Coastal Plain region have very similar correlations betweein bankfull cross section area (R2 = 0.92, n = 123) and discharge (R2 = 0.85, n = 77) with drainage basin area, despite geographic and hydrologic differences. Analysis of these data also shows that bankfull cross section area for southeastern Coastal Plain streams is 47% less than that indicated for other eastern US rivers by Dunne and Leopold (1978). Furthermore, estimates of bankfull discharge have an average return period of 1.14 years on the annual series. These bankfull flows range from 6.2-90% of the 1.5-year flow, often considered to represent the bankfull flow condition, and 4.4-75% of the 2-year flow, which some have suggested for restoration design. The strong correlation of these data supports the concept of using regional morphologic data for initiating assessments and should be considered as an important component of restoration design for streams of the southeastern Coastal Plain.

  9. Cross-Modal Brain Plasticity in Congenital Blindness: Lessons from the Tongue Display Unit

    2011-10-01

    Full Text Available The tongue display unit (TDU is a sensory substitution device that translates visual information into electrotactile stimulation that is applied to the tongue. Blind subjects can learn to use the TDU in various visual tasks, including orientation, motion and shape identification, and spatial navigation. We used the TDU in conjunction with brain imaging techniques in order to study the cerebral correlates of cross-modal brain plasticity. The results show that when blind subjects use the TDU to perform visual tasks that are known to activate the dorsal and ventral visual streams in the sighted, they activate the same brain areas. This suggests that motion and shape processing are organized in a supramodal manner in the human brain and that vision is not necessary for the development of the functional architecture in motion and shape processing areas. We also used the TDU in spatial navigation tasks. The results showed that blind but not blindfolded sighted subjects activated their visual cortex and right parahippocampus during navigation, suggesting that in the absence of vision, cross-modal plasticity permits the recruitment of the same cortical network used for spatial navigation tasks in sighted subjects.

    The purpose of this study was to assess the current status of chiropractic practice laws in the United States. This survey is an update and expansion of 3 original surveys conducted in 1987, 1992, and 1998. A cross-sectional survey of licensure officials from the Federation of Chiropractic Licensing Boards e-mail list was conducted in 2011 requesting information about chiropractic practice laws and 97 diagnostic, evaluation, and management procedures. To evaluate content validity, the survey was distributed in draft form at the fall 2010 Federation of Chiropractic Licensing Boards regional meeting to regulatory board members and feedback was requested. Comments were reviewed and incorporated into the final survey. A duplicate question was imbedded in the survey to test reliability. Partial or complete responses were received from 96% (n = 51) of the jurisdictions in the United States. The states with the highest number of services that could be performed were Missouri (n = 92), New Mexico (n = 91), Kansas (n = 89), Utah (n = 89), Oklahoma (n = 88), Illinois (n = 87), and Alabama (n = 86). The states with the highest number of services that cannot be performed are New Hampshire (n = 49), Hawaii (n = 47), Michigan (n = 42), New Jersey (n = 39), Mississippi (n = 39), and Texas (n = 30). The scope of chiropractic practice in the United States has a high degree of variability. Scope of practice is dynamic, and gray areas are subject to interpretation by ever-changing board members. Although statutes may not address specific procedures, upon challenge, there may be a possibility of sanctions depending on interpretation. Copyright © 2014 National University of Health Sciences.

    To study the acquisition and cross-transmission of Staphylococcus aureus in different intensive care units (ICUs). We performed a multicenter cohort study. Six ICUs in 6 countries participated. During a 3-month period at each ICU, all patients had nasal and perineal swab specimens obtained at ICU admission and during their stay. All S. aureus isolates that were collected were genotyped by spa typing and multilocus variable-number tandem-repeat analysis typing for cross-transmission analysis. A total of 629 patients were admitted to ICUs, and 224 of these patients were found to be colonized with S. aureus at least once during ICU stay (22% were found to be colonized with methicillin-resistant S. aureus [MRSA]). A total of 316 patients who had test results negative for S. aureus at ICU admission and had at least 1 follow-up swab sample obtained for culture were eligible for acquisition analysis. A total of 45 patients acquired S. aureus during ICU stay (31 acquired methicillin-susceptible S. aureus [MSSA], and 14 acquired MRSA). Several factors that were believed to affect the rate of acquisition of S. aureus were analyzed in univariate and multivariate analyses, including the amount of hand disinfectant used, colonization pressure, number of beds per nurse, antibiotic use, length of stay, and ICU setting (private room versus open ICU treatment). Greater colonization pressure and a greater number of beds per nurse correlated with a higher rate of acquisition for both MSSA and MRSA. The type of ICU setting was related to MRSA acquisition only, and the amount of hand disinfectant used was related to MSSA acquisition only. In 18 (40%) of the cases of S. aureus acquisition, cross-transmission from another patient was possible. Colonization pressure, the number of beds per nurse, and the treatment of all patients in private rooms correlated with the number of S. aureus acquisitions on an ICU. The amount of hand disinfectant used was correlated with the number of cases of

    Emergency Response units (ERUs) have been developed as a part of the International Federation of Red Cross and Red Crescent Societies strategy to provide fast and effective medical and technical help to victims of disasters of any kind. ERUs provide timely, professional and organised response in a standardised and streamlined way by a balanced composition of professional staff and predesigned equipment. The German Red Cross ERUs "Referral Hospital" and "Specialised Water" took part in the world wide humanitarian help for refugees during the Kosovo war and actually for earthquake victims in Turkey. During the Kosovo-operation the ERU "Referral Hospital" and "Specialised Water" were situated in Macedonia close to the kosovarian boarder at refugee camp Stenkovec I. The Field-Hospital was responsible for all kind of medical emergencies, for a total number of more than 50,000 refugees. During the mission 6225 patients were treated in our Out Patient Department; 541 were hospitalised. Among those 102 medium and major surgical procedures and 105 deliveries were performed. Surprisingly there was no increased rate of infections or perinatal deaths. During the Kosovo war and actually in Turkey the ERU concept prove itself to be a powerful strategy to provide fast needed medical help to victims of different kind of disasters. Humanitarian work in situations of war, internal disorder and various states of emergency in foreign countries and cultures demand flexibility and the ability to improvise while working under such conditions. The confrontation with non-combatants injured by buried landmines is underlining the growing world-wide demand for a total ban on these vile weapons.

    Patient safety culture (PSC) has an important role in determining safety and quality in healthcare. Currently, little is known about the status of unit-level PSC in hospitals in Japan. To develop appropriate strategies, characteristics of unit-level PSC should be investigated. Work units may be classified according to the characteristics of PSC, and common problems and appropriate strategies may be identified for each work unit category. This study aimed to clarify the characteristics of unit-level PSC in hospitals in Japan. In 2012, a cross-sectional study was conducted at 18 hospitals in Japan. The Hospital Survey on Patient Safety Culture questionnaire, developed by the United States Agency for Healthcare Research and Quality, was distributed to all healthcare workers (n =12,076). Percent positive scores for 12 PSC sub-dimensions were calculated for each unit, and cluster analysis was used to categorise the units according to the percent positive scores. A generalised linear mixed model (GLMM) was used to analyse the results of the cluster analysis, and odds ratios (ORs) for categorisation as high-PSC units were calculated for each unit type. A total of 9,124 respondents (75.6%) completed the questionnaire, and valid data from 8,700 respondents (72.0%) were analysed. There were 440 units in the 18 hospitals. According to the percent positive scores for the 12 sub-dimensions, the 440 units were classified into 2 clusters: high-PSC units (n =184) and low-PSC units (n =256). Percent positive scores for all PSC sub-dimensions for high-PSC units were significantly higher than those for low-PSC units. The GLMM revealed that the combined unit type of 'Obstetrics and gynaecology ward, perinatal ward or neonatal intensive care unit' was significantly more likely to be categorised as high-PSC units (OR =9.7), and 'Long-term care ward' (OR =0.2), 'Rehabilitation unit' (OR =0.2) and 'Administration unit' (OR =0.3) were significantly less likely to be categorised as high

    The emotion of disgust, with feelings of revulsion and behavioral withdrawal, make it a prime emotion to aid in the avoidance of sources of contamination, including sources of potential infectious disease. We tested the theory that living in a region with a historically high prevalence of infectious diseases would promote higher levels of disgust and contamination sensitivity as a protective measure. A sample of undergraduates from Ghana (n = 103, 57 women), a country with a historically high prevalence of infectious diseases, showed significantly higher scores on scales assessing disgust, contamination, and disease susceptibility than a sample of undergraduates from the United States (n = 96, 58 women), a country with lower levels of disease threat. Contamination sensitivity mediated the national differences in disgust. Disgust connoting contamination also produced larger cross-national effect sizes than other types of disgust. Finally, a factor analysis on the Ghanaian responses to one of the disgust scales did not resemble the usual three-factor solution found in West. Taken together, the results were consistent with the hypothesis that a region with a higher prevalence of infectious disease threats would produce greater sensitivity to disgust and contamination than seen in lower disease threat regions. This first study on disgust in Africa showed that disgust sensitivity could differ considerably from that in the West. PMID:23450744

    Full Text Available Background: Blood transfusion as a part health services should be provided under appropriate indications and in a safe manner. In Indonesia, blood collection is run by the Blood Transfusion Unit of Indonesian Red Cross, where the blood is screened, processed into blood components, and finally distributed to hospitals. The purpose of this study was to describe the profile of blood transfusion requests from hospitals that do not have blood bank facility to the Bandung Blood Transfusion Unit, Indonesian Red Cross. Methods: A descriptive study was carried out using secondary data from Bandung Blood Transfusion Unit Indonesian Red Cross (UTD PMI Bandung. All blood request forms from hospitals during 2011 were collected and analyzed. Variables in this study were the amount of blood units, blood components, blood type, and indications of blood transfusion. Results: The number of blood units requested by hospitals were 35,841 units. The most blood units requested was in August 2011. The blood component requested was the packed red cell (61.1%, whole blood (17.4%, thrombocyte concentrate (10.6%, and fresh frozen plasma (7%. The total percentage of O, A, B and AB blood types were 36.1%, 28.6%, 27.5%, and 7.9% respectively. The most frequent indication for transfusion was anemia (61.7%, followed by surgery and other causes of bleeding. Conclusions: The total blood units requested by hospitals vary each month. The most blood component requested is Packed Red Cell and the type of blood is O blood type. The most frequent indication is anemia.

    Full Text Available Two overall goals of this paper are a to provide a linguistic basis for promoting first language maintenance of Vietnamese in a larger United States context and b to stimulate future research in language acquisition of Vietnamese-English speakers. This paper is divided into three sections. Section 1 discusses previous studies on first language (L1 maintenance among Vietnamese Americans. Section 2 presents a cross-linguistic comparison of Vietnamese and English across speech-sound, word, and grammatical language levels. A cross-linguistic analysis may help educators better understand speaking patterns of Vietnamese American students. Based on this cross-linguistic comparison, Section 3 presents potential bi-directional interactions between Vietnamese and English within an individual speaker. These predictions are intended to provide a framework for future empirical studies related to bilingual development.

    Personality traits can predict how well-sojourners and expatriates adjust to new cultures, but the adjustment process remains largely unexamined. Based on recent findings that reveal personality traits predict as well as respond to life events and experiences, this research focuses on within-person change in contextualized extraversion and its predictive validity for cross-cultural adjustment in international students who newly arrived in US colleges. We proposed that the initial level as well as the rate of change in school extraversion (i.e., contextualized extraversion that reflects behavioral tendency in school settings) will predict cross-cultural adjustment, withdrawal cognitions, and school satisfaction. Latent growth modeling of three-wave longitudinal surveys of 215 new international students (54% female, M age = 24 years) revealed that the initial level of school extraversion significantly predicted cross-cultural adjustment, (lower) withdrawal cognitions, and satisfaction, while the rate of change (increase) in school extraversion predicted cross-cultural adjustment and (lower) withdrawal cognitions. We further modeled global extraversion and cross-cultural motivation as antecedents and explored within-person change in school extraversion as a proximal factor that affects adjustment outcomes. The findings highlight the malleability of contextualized personality, and more importantly, the importance of understanding within-person change in contextualized personality in a cross-cultural adjustment context. The study points to more research that explicate the process of personality change in other contexts.

    The integration of nanostructured films containing biomolecules and silicon-based technologies is a promising direction for reaching miniaturized biosensors that exhibit high sensitivity and selectivity. A challenge, however, is to avoid cross talk among sensing units in an array with multiple sensors located on a small area. In this letter, we describe an array of 16 sensing units of a light-addressable potentiometric sensor (LAPS), which was made with layer-by-layer (LbL) films of a poly(amidomine) dendrimer (PAMAM) and single-walled carbon nanotubes (SWNTs), coated with a layer of the enzyme penicillinase. A visual inspection of the data from constant-current measurements with liquid samples containing distinct concentrations of penicillin, glucose, or a buffer indicated a possible cross talk between units that contained penicillinase and those that did not. With the use of multidimensional data projection techniques, normally employed in information visualization methods, we managed to distinguish the results from the modified LAPS, even in cases where the units were adjacent to each other. Furthermore, the plots generated with the interactive document map (IDMAP) projection technique enabled the distinction of the different concentrations of penicillin, from 5 mmol L(-1) down to 0.5 mmol L(-1). Data visualization also confirmed the enhanced performance of the sensing units containing carbon nanotubes, consistent with the analysis of results for LAPS sensors. The use of visual analytics, as with projection methods, may be essential to handle a large amount of data generated in multiple sensor arrays to achieve high performance in miniaturized systems.

    Individualism-collectivism is one of the best researched dimensions of culture in psychology. One frequently asked but underexamined question regards its cross-temporal changes: Are cultures becoming individualistic? One influential theory of cultural change, modernization theory, predicts the rise of individualism as a consequence of economic growth. Findings from past research are generally consistent with this theory, but there is also a body of evidence suggesting its limitations. To examine these issues, cross-temporal analyses of individualism-collectivism in the United States and Japan were conducted. Diverging patterns of cultural changes were found across indices: In both countries, some of the obtained indices showed rising individualism over the past several decades, supporting the modernization theory. However, other indices showed patterns that are best understood within the frameworks of a shifting focus of social relationships and a persisting cultural heritage. A comprehensive theory of cultural change requires considerations of these factors in addition to the modernization effect.

    Full Text Available Using a Social Accounting Matrix as database, a Computable General Equilibrium model is implemented in order to estimate the Indirect Transportations Costs (ITC present in the border crossing for the U.S.–Mexico bilateral trade. Here, an “iceberg–type” transportation function is assumed to determine the amount of loss that must be faced as a result of border crossing process through the ports of entry existing between the two countries. The study period covers annual data from 1995 to 2009 allowing the analysis of the trend of these costs considering the trade liberalisation that is experienced. Results show that the ITC have experienced a decrease of 12% during the period.Test

    1987-01-01

    Recently, utility management, both at the corporate and plant operations levels, have reinforced their commitment to assuring increased plant reliability and availability. One means of achieving this objective involves an effective preventive maintenance program with technical specifications which allow implementation of certain preventive maintenance without plant shutdown. To accomplish this, Southern California Edison Company (SCE) has proposed a design change for San Onofre nuclear generating station (SONGS) units 2 and 3 to permit on emergency diesel generator for one unit to perform as an available AC power source for both units. Technical specifications for SCE's SONGS units 2 and 3, as at most nuclear power plants, currently require plant shutdown should one of the two dedicated onsite emergency AC power sources (diesel generators) become inoperable for more than 72 hours. This duration hinders root cause failure analysis, tends to limit the flexibility of preventive maintenance and precludes plant operation in the event of component failure. Therefore, this proposed diesel generator cross-connect design change offers an innovative means for averting plant shutdown should a single diesel generator become inoperable for longer than 72 hours.

    To assess family satisfaction with care provided to patients in critical care units in Islamabad. A descriptive cross-sectional study was conducted in 11 medical and surgical critical care units at two private hospitals in Islamabad, Pakistan. The purposive sample consisted of 323 immediate family members and other relatives and friends (referred to as family members in this article) of 323 patients admitted to the critical care units for at least 24 hours. The revised Critical Care Family Satisfaction Survey was used for data collection. Descriptive statistics were used for data analysis. A total of 149/323 (46%) family members were 'very satisfied' with the honesty (openness) of staff in explaining the patient's condition, and 137/323 (42%) family members were 'very satisfied' with the nurses' availability to speak to them. A total of 143/323 (44%) family members were 'satisfied' with the honesty (openness) of staff in explaining the patient's condition, and 131/323 (41%) were 'satisfied' with the nurses' availability to speak to them. A few family members (21/323, 6%) were 'very dissatisfied' with the flexibility of the visiting hours and a few (20/323, 6%) were 'very dissatisfied' with the noise level in the critical care units. Some family members (38/323, 12%) were 'not satisfied' with the flexibility of the visiting hours, and some (18/323, 6%) were 'not satisfied' with the noise level in the critical care units. The majority of family members (244/323, 75%) were 'satisfied' or 'very satisfied' that their relatives' needs were being met in the critical care units. However, qualitative data indicate that most family members wanted greater involvement in decision making. These findings should be considered by staff working in critical care settings to ensure high-quality patient care.

    2007-12-01

    To analyze the dynamics of physician international migration patterns and identify the countries deviating most from expected migration rates. A negative binomial log-linear model of physician migration to the United States from every other country was constructed using a panel of country-level data for years 1994-2000. The model was used to identify factors associated with physician migration and to identify countries with higher or lower rates of physician migration than expected. Physician migration varied with a country's GDP per capita in an inverse-U pattern, with highest migration rates from middle-income countries. The absence of medical schools, immigrant networks in the United States, medical instruction in English, proximity to the United States, and the lack of political and civil liberties were also associated with higher migration rates. Countries with higher-than-predicted migration rates included Iceland, Albania, Armenia, Dominica, Lebanon, Syria, the United Arab Emirates, and Bulgaria. Countries with lower-than-predicted migration rates included Mexico, Japan, Brazil, Zimbabwe, Mauritania, Portugal, Senegal, and France. This analysis shows that many of the most powerful factors associated with physician migration are difficult or impossible for countries to change through public policy. GDP per capita and proximity to the U.S. are two of the most powerful predictors of physician migration. Networks of immigrants in the U.S. and fewer political and civil liberties also put countries at higher risk for physician emigration. Several other factors that were associated with physician migration might be more easily amenable to policy intervention. These factors include the absence of a medical school and medical instruction in English. Policies addressing these factors would involve making several difficult tradeoffs, however. Other examples of policies that are effective in minimizing physician migration might be found by examining countries with lower

    The current study was aimed at understanding the social representation of hearing aids in India, Iran, Portugal, and the United Kingdom. We also compared these results to explore the cross-cultural differences and similarities among these countries. The study involved a cross-sectional design, and the data were collected from four different countries using the snowball sampling method. Data were analyzed using a content analysis to identify the most-similar categories of responses reported, a co-occurrences analysis to see which of these categories are reported commonly, and a chi-square analysis to study if there was any association between positive, neutral, and negative connotations among participants in different countries. The current study revealed four different social representations of hearing aids from India, Iran, Portugal, and the United Kingdom, and also a global index. The study results provide very useful insights into how hearing aids are represented in the society. These findings may have important implications for public education and also for manufacturers from the viewpoint of designing and marketing hearing aids in different countries.

    Intense migrations from tuberculosis endemic areas to Gulf countries create special risks to people in the region. The purpose of this study is to provide data that could justify implementing a universal, regular TB screening in UAE. This prospective, cross-sectional study used interferon-γ release assay (IGRA) to screen for TB among Emirati citizens between August-2016 and May-2017; expatriates were not included in this study. Participants were recruited from Emiratis attending Tawam Hospital Polyclinics for problems unrelated to TB risk assessment. IGRA was requested for all enrolled participants. A risk-assessment questionnaire was completed by all participants. In addition, a retrospective review of IGRA results (January-2011 to April-2016) was conducted to compare prevalence of positive IGRA in the 'prospective sample' with that in 'patients screened in the past'. Four hundred fifty-five participants (69% females) were enrolled in this study. Participants' age (mean±SD) was 42±16y. The majority of participants had traveled to or had helpers from TB-endemic areas. Two hundred forty (53%) participants had IGRA test. Forty-five (18.8%) participants had positive IGRA, similar to the retrospective results of 12.4% to 23.5%. The prevalence of positive-IGRA in this study is high. Copyright © 2018.

    Full Text Available BACKGROUND The monitoring of Endotracheal Tube (ETT cuff pressure in intubated patients on arrival to intensive care unit is very essential. The cuff pressure must be within an optimal range of 20-30cm H2O ensuring ventilation with no complications related to cuff overinflation and underinflation. This can be measured with a cuff pressure manometer. The aim of the study is to measure the endotracheal tube cuff pressure in patients on arrival to intensive care unit and to identify prevalence of endotracheal cuff underinflation and overinflation. MATERIALS AND METHODS A cross-sectional study was done on mechanically-ventilated patients who were intubated in casualty (emergency department on arrival to intensive care unit in S.S. Institute of Medical Sciences and Research Centre, Davangere. About 50 critically-ill patients intubated with a high volume, low pressure endotracheal tube were included in the study. An analogue manometer was used to measure the endotracheal tube cuff pressure. It was compared with the recommended level. The settings of mechanical ventilation, endotracheal tube size and peak airway pressure were recorded. RESULTS It was found that the mean cuff pressure was 64.10 cm of H2O with a standard deviation of 32.049. Of the measured cuff pressures, only 2% had pressures within an optimal range (20-30cm of H2O. 88% had cuff pressures more than 30cm of H2O. The mean peak airway pressure found to be 20.50cm of H2O with a Standard Deviation (SD of 5.064. CONCLUSION This study is done to emphasise the importance of cuff pressure measurement in all mechanically-ventilated patients as cuff pressure is found to be high in most of the patients admitted to intensive care unit. Complications of overinflation and underinflation can only be prevented if the acceptable cuff pressures are achieved.

    Full Text Available Background: One of the goals of nursing is providing safe care, prevention of injury, and health promotion of patients. Patient safety in intensive care units is threatened for various reasons. This study aimed to survey patient safety culture from the perspective of nurses in intensive care units. Materials and Methods: This cross-sectional study was conducted in 2016. Sampling was done using the convenience method. The sample consisted of 367 nurses working in intensive care units of teaching hospitals affiliated to Isfahan University of Medical Sciences. Data collection was performed using a two-part questionnaire that included demographic and hospital survey on Patient Safety Culture (HSOPSC questionnaire. Data analysis was done using descriptive statistics (mean and standard deviation. Results: Among the 12 dimensions of safety culture, the nurses assigned the highest score to “team work within units” (97.3% and “Organizational learning-continuous improvement” (84%. They assigned the least score to “handoffs and transitions”(21.1%, “non-punitive response to errors” (24.7%, “Staffing” (35.6%, “Communication openness” (47.5%, and “Teamwork across units” (49.4%. Conclusions: The patient safety culture dimensions have low levels that require adequate attention and essential measures of health care centers including facilitating teamwork, providing adequate staff, and developing a checklist of handoffs and transitions. Furthermore, to increase reporting error and to promote a patient safety culture in intensive care units, some strategies should be adopted including a system-based approach to deal with the error.

    Prior cross-national studies of socioeconomic inequalities in obesity have only compared summary indices of inequality but not specific, policy-relevant dimensions of inequality: (a) shape of the socioeconomic gradient in obesity, (b) magnitude of differentials in obesity across socioeconomic levels and, (c) level of obesity at any given socioeconomic level. We use unique data on two highly comparable societies - U.S. and Canada - to contrast each of these inequality dimensions. Data came from the 2002/2003 Joint Canada/U.S. Survey of Health. We calculated adjusted prevalence ratios (APRs) for obesity (compared to normal weight) by income quintile and education group separately for both nations and, between Canadians and Americans in the same income or education group. In the U.S., every socioeconomic group except the college educated had significant excess prevalence of obesity. By contrast in Canada, only those with less than high school were worse off, suggesting that the shape of the socioeconomic gradient differs in the two countries. U.S. differentials between socioeconomic levels were also larger than in Canada (e.g., PR quintile 1 compared to quintile 5 was 1.82 in the U.S. [95 % CI: 1.52-2.19] but 1.45 in Canada [95 % CI: 1.10-1.91]). At the lower end of the socioeconomic gradient, obesity was more prevalent in the U.S. than in Canada. Our results suggest there is variation between U.S. and Canada in different dimensions of socioeconomic inequalities in obesity. Future research should examine a broader set of nations and test whether specific policies or environmental exposures can explain these differences.

    Many studies conducted in the United States (U.S.) have documented a positivity effect in aging-a tendency for older adults to remember more positive than negative information in comparison to young adults. Despite this cognitive emotional benefit, U.S. adults still hold a more negative view of aging compared to adults in Asia. We hypothesized that these aging stereotypes may contribute to different patterns of age-related emotional memory processing in the two cultures. In the present study, we tested young and older adults in the U.S. and China on a View of Aging task and an emotional picture memory task. Chinese older adults hold a significantly more positive view of aging compared to all other groups of participants. Older adults in both countries demonstrated an age-related positivity effect, but Chinese older adults showed a trend in remembering fewer negative pictures than their American counterparts. These findings suggest that aging stereotypes might significantly influence older adults' cognitive abilities.

    Mobile technology ownership in the general US population and medical professionals is increasing, leading to increased use in clinical settings. However, data on use of mobile technology by psychiatry residents remain unclear. In this study, our aim was to provide data on how psychiatric residents use mobile phones in their clinical education as well as barriers relating to technology use. An anonymous, multisite survey was given to psychiatry residents in 2 regions in the United States, including New Orleans and Boston, to understand their technology use. All participants owned mobile phones, and 79% (54/68) used them to access patient information. The majority do not use mobile phones to implement pharmacotherapy (62%, 42/68) or psychotherapy plans (90%, 61/68). The top 3 barriers to using mobile technology in clinical care were privacy concerns (56%, 38/68), lack of clinical guidance (40%, 27/68), and lack of evidence (29%, 20/68). We conclude that developing a technology curriculum and engaging in research could address these barriers to using mobile phones in clinical practice. ©Shih Gipson, John Torous, Robert Boland, Erich Conrad.

    Harter's Self-Perception Profile for children (SPPC) is a self-reportinginventory for ascertain children's perception of themselves in variousspecific domains of their life, as well as their sense of global self-worth.A few studies have examined the psychometric properties of this instrument inthe Western setting, but none have investigated this in an Arabic culture.Psychometric properties of the SPPC were examined using a sample of 100schoolchildren aged 8 to 16 years in the United Arab Emirates. The internalconsistency reliability was found to be excellent with Chronbach's alpha,ranging from 0.86 to 0.92. Significant age and gender differences were foundwith the internal consistency reliability scores, being higher in childrenaged 13 to 16 years (0.88 to 0.93) when compared to younger children,especially bys aged 8 to 12 years (0.54 to 0.66), suggesting a need toexercise caution while using this scale in young boys in this culture.Behavioral conduct subscale was found to have the highest reliability scoreand the strongest correlation to global self-worth (r=0.54) for both youngerand older children in our sample. This in contract to findings from similarstudies carried out on American and Dutch samples, where this subscale wasfound to have the lowest reliability score and the weakest correlation withone's global self-worth. The findings indicate that the SPPC is a reliableand internally valid instrument for use in the Arab culture. (author)

There is a lack of information about how, when, and where breastfeeding peer support was provided in the U.K. We aimed to generate an overview of how peer support is delivered in the U.K. and to gain an understanding of challenges for implementation. We surveyed all U.K. infant feeding coordinators (n = 696) who were part of U.K.-based National Infant Feeding Networks, covering 177 National Health Service (NHS) organisations. We received 136 responses (individual response rate 19.5%), covering 102 U.K. NHS organisations (organisational response rate 58%). We also searched NHS organisation websites to obtain data on the presence of breastfeeding peer support. Breastfeeding peer support was available in 56% of areas. However, coverage within areas was variable. The provision of training and ongoing supervision, and peer-supporter roles, varied significantly between services. Around one third of respondents felt that breastfeeding peer-support services were not well integrated with NHS health services. Financial issues were commonly reported to have a negative impact on service provision. One quarter of respondents stated that breastfeeding peer support was not accessed by mothers from poorer social backgrounds. Overall, there was marked variation in the provision of peer-support services for breastfeeding in the U.K. A more robust evidence base is urgently needed to inform guidance on the structure and provision of breastfeeding peer-support services. © 2017 John Wiley & Sons Ltd.

    Full Text Available Background: Epidemiological studies have shown that employees working with visual display units (VDU are more likely to complain about musculoskeletal disorders (MSDs. The aim of this study has been to evaluate associations among MSDs and individuals and work-related factors. Material and Methods: A total of 1032 VDU workers were assessed about their personal (i.e., age, working history, smoking history, physical activity and work-related factors (i.e., predominant job tasks performed, work posture. Work environment was evaluated regarding fulfillment of the standard ISO 9241-5:1998. The investigation required a direct observation of participants (in order to accurately assess the prevalence of MSDs and workstations. Adjusted odds ratios (ORa were calculated by means of the logistic regression model. Results: Prevalence of MSDs was relatively high (53%. In general, MSDs were significantly associated with female sex (OR = 2.832, 95% confidence interval (CI: 2.178–3.683, age ≥ 50 years old (OR = 2.231, 95% CI: 1.236–4.026, longer exposure to VDU, both as working history (10–14 years: OR = 1.934, 95% CI: 1.301–2.875; ≥ 15 years: OR = 2.223, 95% CI: 1.510–3.271 and working time (30–39 h/week: OR = 1.537, 95% CI: 1.087–2.273. Inappropriate workstation design was confirmed by the multivariate analysis as a risk factor for MSDs (ORa = 2.375, 95% CI: 1.124–5.018. Conclusions: Musculoskeletal disorders were significantly associated with individual factors as well as characteristics of work environment. An appropriate design of workstations may significantly reduce their prevalence amongst VDU workers. Med Pr 2016;67(6:707–719

    The median emergency department (ED) boarding time for admitted patients has been a nationally reportable core measure that now also affects ED accreditation and reimbursement. However, no direct national probability samples of ED boarding data have been available to guide this policy until now. The authors studied new National Hospital Ambulatory Medical Care Survey (NHAMCS) survey items to establish baseline values, to generate hypotheses for future research, and to help improve survey quality in the future. This was a cross-sectional, multistage, stratified annual analysis of EDs and ED visits from the National Hospital Ambulatory Medical Care Survey public use files from 2007 to 2010, a total of 139,502 visit records. These data represent the only national measure of ED boarding. The main outcome of interest was boarding duration for individual patient visits. Data analyses accounted for complex sampling design. The national median boarding time was 79 minutes, with an interquartile range of 36 to 145 minutes. The prevalence of boarding for more than 2 hours among admitted patients was 32% (95% confidence interval [CI] = 30% to 35%). Average ED volume, occupancy, acuity, and hospital admission rates increased abruptly from the second to the third quartile of median boarding duration. The half of hospitals with the longest median boarding times accounted for 73% of ED visits and 79% of ED hospitalizations nationally. Thirty-nine percent of EDs (95% CI = 32% to 46%) reported never holding patients for more than 2 hours, but visit-level analysis at these EDs found that 21% of admissions did in fact stay in the ED over 2 hours. Only 19% of EDs (95% CI = 16% to 22%) used a strategy of moving admitted patients to alternative sites in the hospital during crowded times. In this national survey, ED boarding of admitted patients disproportionately affects hospitals with higher ED volumes, which also see sicker patients who wait longer to be seen, but not hospitals with

    Aims The objective of this paper is to perform a cross-cultural comparison of gambling disorder (GD) due to electronic gaming machines (EGM), a form of gambling that may have a high addictive potential. Our goal is to investigate two treatment-seeking samples of adults collected in Brazil and the United States, countries with different socio-cultural backgrounds. This comparison may lead to a better understanding of cultural influences on GD. Methods The total studied sample involved 733 treatment-seeking subjects: 353 men and 380 women (average age = 45.80, standard deviation ±10.9). The Brazilian sample had 517 individuals and the American sample 216. Subjects were recruited by analogous strategies. Results We found that the Brazilian sample was younger, predominantly male, less likely to be Caucasian, more likely to be partnered, had a faster progression from recreational gambling to GD, and were more likely to endorse chasing losses. Conclusion This study demonstrated that there are significant differences between treatment-seeking samples of adults presenting GD due to EGM in Brazil and in the United States. These findings suggest that cultural aspects may have a relevant role in GD due to EGM. PMID:26474662

    Ensuring the safety of hospitalized patients remains a major challenge for healthcare systems, and nursing services are at the center of hospital care. Yet our knowledge about safety of nursing care is quite limited. In fact, most earlier studies examined one, or at most two, indicators, thus presenting an incomplete picture of safety at an institutional or broader level. Furthermore, methodologies have differed from one study to another, making benchmarking difficult. The aim of this study was to describe the frequencies of six adverse events widely considered in the literature to be nursing-sensitive outcomes and to estimate the degree to which these events could be attributed to nursing care. Cross-sectional review of charts of 2699 patients hospitalized on 22 medical units in 11 hospitals in Quebec, Canada. The events included: pressure sores, falls, medication administration errors, pneumonias, urinary infections, and inappropriate use of restraints. Experienced nurse reviewers abstracted patients' charts based on a grid developed for the study. Patient-level risk for at least one of these six adverse events was 15.3%, ranging from 9% to 28% across units. Of the 412 patients who experienced an event, 30% experienced two or more, for a total of 568 events. The risk of experiencing an adverse event with consequences was 6.2%, with a unit-level range from 3.2% to 13.5%. Abstractors concluded that 76.8% of the events were attributable to nursing care. While the measurement approach adopted here has limitations stemming from reliance on review of documentation, it provided a practical means of assessing several nursing-sensitive adverse events simultaneously. Given that patient safety issues are so complex, tracking their prevalence and impact is important, as is finding means of evaluating progress in reducing them. Crown Copyright © 2013.

    Full Text Available Counties are the smallest unit for which mortality data are routinely available, allowing consistent and comparable long-term analysis of trends in health disparities. Average life expectancy has steadily increased in the United States but there is limited information on long-term mortality trends in the US counties This study aimed to investigate trends in county mortality and cross-county mortality disparities, including the contributions of specific diseases to county level mortality trends.We used mortality statistics (from the National Center for Health Statistics [NCHS] and population (from the US Census to estimate sex-specific life expectancy for US counties for every year between 1961 and 1999. Data for analyses in subsequent years were not provided to us by the NCHS. We calculated different metrics of cross-county mortality disparity, and also grouped counties on the basis of whether their mortality changed favorably or unfavorably relative to the national average. We estimated the probability of death from specific diseases for counties with above- or below-average mortality performance. We simulated the effect of cross-county migration on each county's life expectancy using a time-based simulation model. Between 1961 and 1999, the standard deviation (SD of life expectancy across US counties was at its lowest in 1983, at 1.9 and 1.4 y for men and women, respectively. Cross-county life expectancy SD increased to 2.3 and 1.7 y in 1999. Between 1961 and 1983 no counties had a statistically significant increase in mortality; the major cause of mortality decline for both sexes was reduction in cardiovascular mortality. From 1983 to 1999, life expectancy declined significantly in 11 counties for men (by 1.3 y and in 180 counties for women (by 1.3 y; another 48 (men and 783 (women counties had nonsignificant life expectancy decline. Life expectancy decline in both sexes was caused by increased mortality from lung cancer, chronic obstructive

    Full Text Available BACKGROUND: Although La Crosse virus (LACV is one of the most common causes of pediatric arboviral infections in the United States, little has been done to assess its geographic distribution, identify areas of higher risk of disease, and to provide a national picture of its clinical presentation. Therefore, the objective of this study was to investigate the geographic distribution of LACV infections reported in the United States, to identify hot-spots of infection, and to present its clinical picture. METHODS AND FINDINGS: Descriptive and cluster analyses were performed on probable and confirmed cases of LACV infections reported to the Centers for Disease Control and Prevention from 2003-2007. A total of 282 patients had reported confirmed LACV infections during the study period. Of these cases the majority (81 percent presented during the summer, occurred in children 15 years and younger (83.3 percent, and were found in male children (64.9 percent. Clinically, the infections presented as meningioencephalitis (56.3 percent, encephalitis (20.7 percent, meningitis (17.2 percent, or uncomplicated fever (5 percent. Deaths occurred in 1.9 percent of confirmed cases, and in 8.6 percent of patients suffering from encephalitis. The majority of these deaths were in patients 15 years and younger. The county-level incidence risk among counties (n = 136 reporting both probable and confirmed cases for children 15 years and younger (n = 355 ranged from 0.2 to 228.7 per 100,000 persons. The southern United States experienced a significantly higher (p<0.05 incidence risk during the months of June, July, August, and October then the northern United States. There was significant (p<0.05 clustering of high risk in several geographic regions with three deaths attributed to complications from LAC encephalitis occurring in two of these hot-spots of infections. CONCLUSIONS: Both the incidence risk and case fatality rates were found to be higher than previously

    Full Text Available Objective: To perform a cross-cultural comparison of gambling disorder (GD in women from Brazil and the United States, two countries with pronounced social and cultural differences. We hoped to produce insight into the impact of cultural influences on the presentation of GD in women, which may be useful for the development of culturally-sensitive interventions. Method: We assessed 681 women with GD: 406 from a Brazilian sample and 275 from a U.S. sample. We assessed demographic and gambling behavior variables in addition to co-occurring psychiatric disorders. Results: Fewer Brazilian participants were Caucasian (73.3 vs. 91.3%; p = 0.022. Also, Brazilian women had lower levels of education (59.9% with high school or less vs. 44.4%; p < 0.001, and were more likely to have a current partner (54.9 vs. 43.4%; p = 0.003. Brazilian gamblers also reported lower urge scores (6.6±4.3 vs. 11.6±2.4; p < 0.001 and higher chasing rates (89.1 vs. 80.0%; p = 0.002. Brazilian gamblers reported higher rates of bingo gambling (19.2 vs. 5.7%; p < 0.001, but lower rates of card game gambling (5.8 vs. 23.1%; p < 0.001. Finally, Brazilian gamblers were more likely to endorse a history of major depressive disorder (36.9 vs. 24.4%; p = 0.001. Conclusions: This study reinforces the need for further general cross-cultural research on GD and particularly for studies investigating how gender mediates these differences. Finally, the differences noted in this analysis suggest that the findings of predominantly Anglo-Saxon cultures may not be generalizable to other world populations.

    Full Text Available ABSTRACT Objective: to determine the frequency of pain, to verify the measures adopted for pain relief during the first seven days of hospitalization in the Neonatal Intensive Care Unit and to identify the type and frequency of invasive procedures to which newborns are submitted. Method: cross-sectional retrospective study. Out of the 188 hospitalizations occurred during the 12-month period, 171 were included in the study. The data were collected from the charts and the presence of pain was analyzed based on the Neonatal Infant Pain Scale and on nursing notes suggestions of pain. For statistical analysis, the Statistical Package for the Social Sciences was used, and the significance level was set at 5%. Results: there was at least one record of pain in 50.3% of the hospitalizations, according to the pain scale adopted or nursing note. The newborns underwent a mean of 6.6 invasive procedures per day. Only 32.5% of the pain records resulted in the adoption of pharmacological or non-pharmacological intervention for pain relief. Conclusion: newborns are frequently exposed to pain and the low frequency of pharmacological or non-pharmacological interventions reinforces the undertreatment of this condition.

    Although OCD is a global problem, the literature comparing, in a direct and standardized way, the manifestations across countries is scarce. Therefore, questions remain as to whether some important clinical findings are replicable worldwide, especially in the developing world. The objective of this study was to perform a clinical comparison of OCD patients recruited in the United States (U.S.) and Brazil. Our sample consisted of 1187 adult, treatment-seeking OCD outpatients from the U.S. (n=236) and Brazil (n=951). With regards to the demographics, U.S. participants with OCD were older, more likely to identify as Caucasian, had achieved a higher educational level, and were less likely to be partnered when compared to Brazilians. Concerning the clinical variables, after controlling for demographics the two samples presented largely similar profiles. Brazilian participants with OCD, however, endorsed significantly greater rates of generalized anxiety disorder and post-traumatic stress disorder, whereas U.S. subjects were significantly more likely to endorse a lifetime history of addiction (alcohol-use and substance-use disorders). This is the largest direct cross-cultural comparison to date in the OCD field. Our results provide much needed insight regarding the development of culture-sensitive treatments.

    Several studies show that cross-transmission of germs among patients under dialysis can occur as a consequence of processes in which the dialysis machine participates. The need of vascular access and lengthy periods of extracorporeal circulation increases the vulnerability to infection from nearby microorganisms. This study is intended to analyze the structural and dynamic features of the cross-transmission network generated by the propagation of germs which are capable of contaminating the hemodialyzers. The simulation was carried out in a Dialysis Unit equipped with 19 machines for 62 patients. One of these patients was randomly chosen and considered as a carrier of an infectious agent capable of being transmitted to other patients, by means of the shared use of the same dialysis machine. For 10 days, the patient-machine allocation couples were registered. Co-occurrence matrices were elaborated and processed with the program UCINET 6.1 for social network analysis. Graphs were designed to visualize the networks of contagion, the centrality measures were calculated and the dynamic performance of the network generated by the chaining of the successive exposures of machines and patients was studied. The simulation let us visualize a rapid expansion of the risk of contagion of patients and contamination of machines. In 10 days, 87,09% of patients could have been exposed to the infection, and 68,42% of the machines could have been contaminated. These figures supposes that 5,4 new patients and 1,3 new machines could be potentially exposed every day. Along the first 5 days, the daily rate of exposure for patients and machines remains relatively low (3 new exposed patients and 1,2 new exposed machines every day). But the speed with witch the risk of contagion spreads, increases drastically in the last 5 days (7,8 new exposed patients every day). The fact that each patient requires at least 3 weekly sessions of dialysis and that a different machine can be allocated to him

    Listeria monocytogenes is among the foodborne pathogens with the highest death toll in the United States. Ready-to-eat foods contaminated at retail are an important source of infection. Environmental sites in retail deli operations can be contaminated. However, commonly contaminated sites are unlikely to come into direct contact with food and the public health relevance of environmental contamination has remained unclear. To identify environmental sites that may pose a considerable cross-contamination risk, to elucidate potential transmission pathways, and to identify knowledge gaps, we performed a structured expert elicitation of 41 experts from state regulatory agencies and the food retail industry with practical experience in retail deli operations. Following the "Delphi" method, the elicitation was performed in three consecutive steps: questionnaire, review and discussion of results, second questionnaire. Hands and gloves were identified as important potential contamination sources. However, bacterial transfers to and from hands or gloves represented a major data gap. Experts agreed about transfer probabilities from cutting boards, scales, deli cases, and deli preparation sinks to product, and about transfer probabilities from floor drains, walk-in cooler floors, and knife racks to food contact surfaces. Comparison of experts' opinions to observational data revealed a tendency among experts with certain demographic characteristics and professional opinions to overestimate prevalence. Experts' votes clearly clustered into separate groups not defined by place of employment, even though industry experts may have been somewhat overrepresented in one cluster. Overall, our study demonstrates the value and caveats of expert elicitation to identify data gaps and prioritize research efforts. © 2011 Society for Risk Analysis.

    Involvement in dating violence has been linked with negative health outcomes including depressive symptomology, substance use, and later expressions of aggressing and victimizing behaviors. Less is known about the prevalence and mental health correlates of teen dating violence in countries like Mexico where adult partner violence is high. Additional research on teen dating violence is also needed, as it may be an important precursor to adult partner violence and linked to other mental health problems. The current study used self-report ratings to assess the similarities and differences in risk factors associated with dating violence among middle school students in Mexico and the United States. The US sample (N us  = 15,099; M us  = 12.8; 49.5% female) included non-Hispanic Caucasian (24.9%), Hispanic American (20.3%), and African American (24.2%) adolescents. The Mexican sample (N Mexico  = 2211; M Mexico  = 13.67; 51% female) included 93.1% adolescents of Hispanic or Latin descent. Logistic regressions showed that dating violence victimization was reported at similar rates in the cross-national samples, though exposure to risk factors like deviant peers and substance use differed significantly by country. Our analyses indicated that, although the country of residence was not significantly associated with dating violence victimization, the strength of the association between some known risk factors and dating violence victimization varied as a function of nationality, such that there was a significant interaction between country of residence, Mexico or the US, and experiencing internalizing symptoms on experiencing physical dating violence victimization. This study contributes to the growing body of literature on dating violence, both inside and outside the US.

    Full Text Available Purpose The purpose of this study was to cross-validate the factor structure of the previously developed Student Perceptions of Team-Based Learning (TBL Scale among students in an entry-level doctor of physical therapy (DPT program in the United States. Methods Toward the end of the semester in 2 patient/client management courses taught using TBL, 115 DPT students completed the Student Perceptions of TBL Scale, with a response rate of 87%. Principal component analysis (PCA and confirmatory factor analysis (CFA were conducted to replicate and confirm the underlying factor structure of the scale. Results Based on the PCA for the validation sample, the original 2-factor structure (preference for TBL and preference for teamwork of the Student Perceptions of TBL Scale was replicated. The overall goodness-of-fit indices from the CFA suggested that the original 2-factor structure for the 15 items of the scale demonstrated a good model fit (comparative fit index, 0.95; non-normed fit index/Tucker-Lewis index, 0.93; root mean square error of approximation, 0.06; and standardized root mean square residual, 0.07. The 2 factors demonstrated high internal consistency (alpha= 0.83 and 0.88, respectively. DPT students taught using TBL viewed the factor of preference for teamwork more favorably than preference for TBL. Conclusion Our findings provide evidence supporting the replicability of the internal structure of the Student Perceptions of TBL Scale when assessing perceptions of TBL among DPT students in patient/client management courses.

    Frailty describes the aging-associated loss of physiological and psychological reserves, leading to an increased risk of adverse health outcomes. Many developed countries view frailty as a major priority for their health and social care systems. Less is known about frailty in less-developed countries. The purpose of this study was to determine the prevalence of frailty in a sample of community-dwelling older people in the United Arab Emirates (UAE). This was a cross-sectional study of community-dwelling Emirati adults aged 55 years and older (n = 160) in Abu Dhabi, UAE. Data were collected at interview by questionnaire and physical measurements. Frailty was defined according to the criteria of the Fried Frailty Index. The prevalence of frailty and its association with selected independent variables were assessed. The overall prevalence of frailty (95% CI) was 47% (39-55). Higher levels of frailty were seen in older age groups, women, those who were non-married, those with recent hospital admission, those with comorbid conditions, those on more than five medications, and those with lower forced expiratory volume and mini-mental state examination score. After adjustment in a multiple logistic regression model, only age and gender were found to be independently associated with frailty. A high prevalence of frailty was found among older Emiratis. Given that frailty is associated with adverse health outcomes and can be a means of identifying opportunities for intervention in clinical practice and health policy, further attention and consideration within professional and public health policy circles are needed.

    The goal of the study was to show that cross-sectional and longitudinal data yield dramatically different answers to a basic question: "How did older persons fare in the recovery years of the 1980s?" The United States Panel Study of Income Dynamics and the German Socio-Economic Panel are used cross-sectionally to capture changes in the economic well-being of older persons in the trough and peak years of the 1980s business cycle, and longitudinally to trace how the economic well-being of a given cohort of older persons changed over those years. Kernel density estimation is then used to show how the distribution of economic well-being of these populations changed over these years. Cross-sectional comparisons confirm that persons aged 65 and over in the peak year were better off than persons aged 65 and over in the trough year in both countries. Longitudinal comparisons, however, show that persons aged 65 and over in the trough year who survived to the peak year received a substantially smaller share of the rewards of economic recovery than cross-sectional comparisons imply. Moreover, the entire income distribution of older persons in the United States shifted downwards. Compositional changes in the cross-sectional data, caused by the entry of high-income persons who are young in the peak year but old in the trough year, obscure the decline in the economic well-being of the cohort of older persons who survived the trough year, in cross-sectional comparisons of older populations in the United States in the 1980s.

    The objective was to compare the characteristics of medication errors reported to 2 national error reporting systems by conducting a cross-sectional analysis of errors reported from adult intensive care units to the UK National Reporting and Learning System and the US MedMarx system. Outcome measures were error types, severity of patient harm, stage of medication process, and involved medications. The authors analyzed 2837 UK error reports and 56 368 US reports. Differences were observed between UK and US errors for wrong dose (44% vs 29%), omitted dose (8.6% vs 27%), and stage of medication process (prescribing: 14% vs 49%; administration: 71% vs 42%). Moderate/severe harm or death was reported in 4.9% of UK versus 3.4% of US errors. Gentamicin was cited in 7.4% of the UK versus 0.7% of the US reports (odds ratio = 9.25). There were differences in the types of errors reported and the medications most often involved. These differences warrant further examination.

    Urban sprawl has the potential to influence cancer mortality via direct and indirect effects on obesity, access to health services, physical activity, transportation choices and other correlates of sprawl and urbanization. This paper presents a cross-sectional analysis of associations between urban sprawl and cancer mortality in urban and suburban counties of the United States. This ecological analysis was designed to examine whether urban sprawl is associated with total and obesity-related cancer mortality and to what extent these associations differed in different regions of the US. A major focus of our analyses was to adequately account for spatial heterogeneity in mortality. Therefore, we fit a series of regression models, stratified by gender, successively testing for the presence of spatial heterogeneity. Our resulting models included county level variables related to race, smoking, obesity, access to health services, insurance status, socioeconomic position, and broad geographic region as well as a measure of urban sprawl and several interactions. Our most complex models also included random effects to account for any county-level spatial autocorrelation that remained unexplained by these variables. Total cancer mortality rates were higher in less sprawling areas and contrary to our initial hypothesis; this was also true of obesity related cancers in six of seven U.S. regions (census divisions) where there were statistically significant associations between the sprawl index and mortality. We also found significant interactions (p urban sprawl for total and obesity related cancer mortality in both sexes. Thus, the association between urban sprawl and cancer mortality differs in different regions of the US. Despite higher levels of obesity in more sprawling counties in the US, mortality from obesity related cancer was not greater in such counties. Identification of disparities in cancer mortality within and between geographic regions is an ongoing public

    The relative ease of movement of physicians across the Canada/US border has led to what is sometimes referred to as a 'brain drain' and previous analysis estimated that the equivalent of two graduating classes from Canadian medical schools were leaving to practice in the US each year. Both countries fill gaps in physician supply with international medical graduates (IMGs) so the movement of Canadian trained physicians to the US has international ramifications. Medical school enrolments have been increased on both sides of the border, yet there continues to be concerns about adequacy of physician human resources. This analysis was undertaken to re-examine the issue of Canadian physician migration to the US. We conducted a cross-sectional analysis of the 2015 American Medical Association (AMA) Masterfile to identify and locate any graduates of Canadian schools of medicine (CMGs) working in the United States in direct patient care. We reviewed annual reports of the Canadian Resident Matching Service (CaRMS); the Canadian Post-MD Education Registry (CAPER); and the Canadian Collaborative Centre for Physician Resources (C3PR). Beginning in the early 1990s the number of CMGs locating in the U.S. reached an all-time high and then abruptly dropped off in 1995. CMGs are going to the US for post-graduate training in smaller numbers and, are less likely to remain than at any time since the 1970's. This four decade retrospective found considerable variation in the migration pattern of CMGs to the US. CMGs' decision to emigrate to the U.S. may be influenced by both 'push' and 'pull' factors. The relative strength of these factors changed and by 2004, more CMGs were returning from abroad than were leaving and the current outflow is negligible. This study supports the need for medical human resource planning to assume a long-term view taking into account national and international trends to avoid the rapid changes that were observed. These results are of importance to medical

    The genetics of suicide is increasingly recognized and relevant for mental health literacy, but actual beliefs may lag behind current knowledge. We examined such beliefs in student samples (total N = 686) from Estonia, Malaysia, Romania, the United Kingdom, and the United States with the Beliefs in the Inheritance of Risk Factors for Suicide Scale. Cultural effects were small, those of key demographics nil. Several facets of construct validity were demonstrated. Marked differences in perceived plausibility of evidence about the genetics of suicide according to research design, observed in all samples, may be of general interest for investigating lay theories of abnormal behavior and communicating behavioral and psychiatric genetic research findings.

    Accounting for one fifth of all crashes and one sixth of all fatal crashes in the United States, intersection crashes are among the most frequent and fatal crash modes. Intersection advanced driver assistance systems (I-ADAS) are emerging vehicle-based active safety systems that aim to help drivers safely navigate intersections. The objective of this study was to estimate the number of crashes and number of vehicles with a seriously injured driver (Maximum Abbreviated Injury Scale [MAIS] 3+) that could be prevented or reduced if, for every straight crossing path (SCP) intersection crash, one of the vehicles had been equipped with an I-ADAS. This study retrospectively simulated 448 U.S. SCP crashes as if one of the vehicles had been equipped with I-ADAS. Crashes were reconstructed to determine the path and speeds traveled by the vehicles. Cases were then simulated with I-ADAS. A total of 30 variations of I-ADAS were considered in this study. These variations consisted of 5 separate activation timing thresholds, 3 separate computational latency times, and 2 different I-ADAS response modalities (i.e., a warning or autonomous braking). The likelihood of a serious driver injury was computed for every vehicle in every crash using impact delta-V. The results were then compiled across all crashes in order to estimate system effectiveness. The model predicted that an I-ADAS that delivers an alert to the driver has the potential to prevent 0-23% of SCP crashes and 0-25% of vehicles with a seriously injured driver. Conversely, an I-ADAS that autonomously brakes was found to have the potential to prevent 25-59% of crashes and 38-79% of vehicles with a seriously injured driver. I-ADAS effectiveness is a strong function of design. Increasing computational latency time from 0 to 0.5 s was found to reduce crash and injury prevention estimates by approximately one third. For an I-ADAS that delivers an alert, crash/injury prevention effectiveness was found to be very sensitive to

    Effectiveness of intensive care treatment is essential to cope with increasing costs. The German national register of intensive care established by the German Interdisciplinary Association for Intensive Care Medicine (DIVI) contains basic data on the structure of intensive care units in Germany. A repeat analysis of data of the DIVI register within 8 years provides information for the development of intensive care units under different economic circumstances. The recent data on the structure of intensive care units were obtained in 2008 and compared with the primary multicenter study from 2000. The hospitals selected were a representative sample for the whole of Germany. Data on the status of the hospital, staff and technical facilities, foundation of the hospital and the statistics of mechanically ventilated patients were analyzed. The technical facilities and the number of staff have improved from 2000 to 2008. A smaller availability of diagnostic procedures and staff remain in hospitals for basic treatment outside normal working hours. The average utilization of intensive care unit beds was not altered. The existence of intermediate care units did not significantly change the proportion of patients with artificial ventilation or ventilation times. The number of beds in intensive care units was unchanged as was the average number of beds in units and the number of patients treated. A relevant number of beds of intensive care units shifted towards hospitals with private foundation without changes in the overall numbers. The structure of the hospitals was comparable at both time points. The introduction of intermediate care units did not alter ventilation parameters of patients in 2008 compared with 2000. There is no obvious medical reason for the shift of intensive care beds towards private hospitals. The number of staff and patients varied considerably between the intensive care units. The average number of patients treated per bed was not different between the

    Assessment of the knowledge and application as well as perceived utility by doctors of clinical governance tools in order to explore their impact on clinical units' performance measured through mortality rates and efficiency indicators. This research is a cross-sectional study with a deterministic record-linkage procedure. The sample includes n = 1250 doctors (n = 249 chiefs of clinical units; n = 1001 physicians) working in six public hospitals located in the Emilia-Romagna Region in Italy. Survey instruments include a checklist and a research-made questionnaire which were used for data collection about doctors' knowledge and application as well as perceived utility of clinical governance tools. The analysis was based on clinical units' performance indicators which include patients' mortality, extra-region active mobility rate, average hospital stay, bed occupancy, rotation and turnover rates, and the comparative performance index as efficiency indicators. The clinical governance tools are known and applied differently in all the considered clinical units. Significant differences emerged between roles and organizational levels at which the medical leadership is carried out. The levels of knowledge and application of clinical governance practices are correlated with the clinical units' efficiency indicators (bed occupancy rate, bed turnover interval, and extra-region mobility). These multiple linear regression analyses highlighted that the clinical governance knowledge and application is correlated with clinical units' mortality rates (odds ratio, -8.677; 95% confidence interval, -16.654, -0.700). The knowledge and application, as well as perceived utility by medical professionals of clinical governance tools, are associated with the mortality rates of their units and with some efficiency indicators. However, the medical frontline staff seems to not consider homogeneously useful the clinical governance tools application on its own clinical practice.

    The quality of water from dental units is of considerable importance since patients and dental staff are regularly exposed to water and aerosols generated from the dental unit. This study analyzed the microbial quality of water obtained for periodical monitoring from 56 dental units in different dental practices in Hesse. Contamination by Legionella spp., Pseudomonas aeruginosa, and increased total colony counts were detected in 27.8%, 3.5%, and 17% of samples. Legionella pneumophila serogroup 1 accounted for 28% of Legionella isolates. The Legionella concentration was >100 cfu/100 ml in 84% of contaminated samples. Samples collected from an instrument channel were more frequently contaminated by Legionella than those from cup filler (41.7% vs. 18.6%, p = 0.02). After release of these results, decontamination measures were performed in units that had revealed unsatisfactory results. The outcome of the intervention was followed-up by microbiological analysis. At follow-up, 65.2% and 72.7% of waterlines that had previously been contaminated by Legionella or had shown increased total colony counts were free of contamination. Our results show a high rate of contamination of water from dental units in dental practices in Hesse. They highlight the risk of exposure for patients and personnel and the need for effective strategies to reduce microbial contamination.

    To evaluate the quality of doctoral education in nursing in the United Kingdom. In recent decades, doctoral education programmes in nursing are increasing worldwide. There are many reasons for this and concerns have been raised regarding the quality of provision in and across countries. To date, the quality of doctoral education on a global level has not been reported in the literature. This United Kingdom study is part of a seven country investigation into the quality of doctoral education in nursing (Australia, Japan, Korea, South Africa, Thailand, United Kingdom and United States of America). A quantitative study using a cross-sectional comparative survey design. An online survey was administered to collect the views of doctoral students and staff members on four domains: programme, faculty/staff, resource and evaluation. The study was carried out between 2010-2012. In most cases, staff perceived these more positively than students and the differences in perception were often statistically significant. Interestingly, many students rated the quality of supervision as excellent, whereas no staff member rated supervision this highly. The crucial importance of resources was confirmed in the path analysis of the four Quality of Doctoral Nursing Education domains. This demonstrates that investment in resources is much more cost-effective than investment in the other domains in relation to improving the overall quality of doctoral education in nursing. This study has wide-ranging implications for how the quality of doctoral education is monitored and enhanced. © 2013 John Wiley & Sons Ltd.

    Doubly differential cross sections of the reaction 90 Zr(n,p) 90 Y have been measured at 200 MeV for excitations up to 38 MeV in the residual nucleus. An overall resolution of 1.3 MeV was achieved. The spectra show qualitative agreement in shape and magnitude with recent RPA calculations; however all of the calculations underestimate the high excitation region of the spectra. A multipole decomposition of the data has been performed using differential cross sections calculated in the DWIA. An estimate of the Gamow-Teller strength in the reaction is given. The isovector spin-flip dipole giant resonance has been identified and there is also an indication of isovector monopole strength. 39 refs., 16 figs., 1 tab

    2017-11-01

    Full Text Available Background This article conducts a comparative national and subnational government analysis of the political, economic, and ideational constructivist contextual factors facilitating the adoption of obesity and diabetes policy. Methods We adopt a nested analytical approach to policy analysis, which combines cross-national statistical analysis with subnational case study comparisons to examine theoretical prepositions and discover alternative contextual factors; this was combined with an ideational constructivist approach to policy-making. Results Contrary to the existing literature, we found that with the exception of cross-national statistical differences in access to healthcare infrastructural resources, the growing burden of obesity and diabetes, rising healthcare costs and increased citizens’ knowledge had no predictive affect on the adoption of obesity and diabetes policy. We then turned to a subnational comparative analysis of the states of Mississippi in the United States and Rio Grande do Norte in Brazil to further assess the importance of infrastructural resources, at two units of analysis: the state governments versus rural municipal governments. Qualitative evidence suggests that differences in subnational healthcare infrastructural resources were insufficient for explaining policy reform processes, highlighting instead other potentially important factors, such as state-civil societal relationships and policy diffusion in Mississippi, federal policy intervention in Rio Grande do Norte, and politicians’ social construction of obesity and the resulting differences in policy roles assigned to the central government. Conclusion We conclude by underscoring the complexity of subnational policy responses to obesity and diabetes, the importance of combining resource and constructivist analysis for better understanding the context of policy reform, while underscoring the potential lessons that the United States can learn from Brazil.

    To analyze the nutritional status of schoolchildren from Bumbire Island (Tanzania) from cross-sectional and longitudinal perspectives. During 2014 and 2015, we collected anthropometric measurements in a sample of 437 schoolchildren (226 males, 211 females; 5-16 years). A sub-sample of 126 children were measured in both surveys. Socio-demographic data have been taken and dietary habits investigated. The accuracy of age data was checked. Malnutrition prevalence was calculated according to the WHO references and the z-score criteria. The prevalence of undernutrition was high (stunting: 30.7%; underweight: 12.9%; thinness: 4.5%), while overweight was rare (2.4%). The prevalence of stunting was higher in males and in older children. The one-year longitudinal analysis indicated that stunting prevalence increased. Undernutrition is affecting Bumbire Island children, likely due to micronutrient deficiencies. The effects of linear growth deficit continue to accumulate throughout childhood and adolescent years. © 2018 Wiley Periodicals, Inc.

    In May 2014, a short-term study-abroad experience was conducted in Finland through a course offered at Indiana State University (ISU). Students and faculty from ISU and Eastern Illinois University participated in the experience, which was created to facilitate a cross-cultural comparison of long-term-care settings in the United States and Finland. With its outstanding system of caring for the health and social needs of its aging populace, Finland is a logical model to examine when considering ways to improve the quality of life for older adults who require care in the United States . Those participating in the course visited a series of long-term-care facilities in the region surrounding Terre Haute, Indiana, then travelled to Lappeenranta, Finland to visit parallel sites. Through limited-participation observation and semistructured interviews, similarities and differences in experiences, educations, and policies affecting long-term care workers in the United States and Finland were identified and are described here.

    Comparative histories of health system development have been variously influenced by the theoretical approaches of historical institutionalism, political pluralism, and labor mobilization. Britain and the United States have figured significantly in this literature because of their very different trajectories. This article explores the implications of recent research on hospital history in the two countries for existing historiographies, particularly the coming of the National Health Service in Britain. It argues that the two hospital systems initially developed in broadly similar ways, despite the very different outcomes in the 1940s. Thus, applying the conceptual tools used to explain the U.S. trajectory can deepen appreciation of events in Britain. Attention focuses particularly on working-class hospital contributory schemes and their implications for finance, governance, and participation; these are then compared with Blue Cross and U.S. hospital prepayment. While acknowledging the importance of path dependence in shaping attitudes of British bureaucrats toward these schemes, analysis emphasizes their failure in pressure group politics, in contrast to the United States. In both countries labor was also crucial, in the United States sustaining employment-based prepayment and in Britain broadly supporting system reform.

    Despite the increasing use of near-infrared spectroscopy across pediatric cardiac ICUs, there is significant variability and equipoise with no universally accepted management algorithms. We aimed to explore the use of near-infrared spectroscopy in pediatric cardiac ICUs in the United Kingdom, Ireland, Italy, and Germany. A cross-sectional multicenter, multinational electronic survey of one consultant in each pediatric cardiac ICU. Pediatric cardiac ICUs in the United Kingdom and Ireland (n = 13), Italy (n = 12), and Germany (n = 33). Questionnaire targeted to establish use, targets, protocols/thresholds for intervention, and perceived usefulness of near-infrared spectroscopy monitoring. Overall, 42 of 58 pediatric cardiac ICUs (72%) responded: United Kingdom and Ireland, 11 of 13 (84.6%); Italy, 12 of 12 (100%); and Germany, 19 of 33 (57%, included all major centers). Near-infrared spectroscopy usage varied with 35% (15/42) reporting that near-infrared spectroscopy was not used at all (7/42) or occasionally (8/42); near-infrared spectroscopy use was much less common in the United Kingdom (46%) when compared with 78% in Germany and all (100%) in Italy. Only four units had a near-infrared spectroscopy protocol, and 18 specifically used near-infrared spectroscopy in high-risk patients; 37 respondents believed that near-infrared spectroscopy added value to standard monitoring and 23 believed that it gave an earlier indication of deterioration, but only 19 would respond based on near-infrared spectroscopy data alone. Targets for absolute values and critical thresholds for intervention varied widely between units. The reasons cited for not or occasionally using near-infrared spectroscopy were expense (n = 6), limited evidence and uncertainty on how it guides management (n = 4), difficulty in interpretation, and unreliability of data (n = 3). Amongst the regular or occasional near-infrared spectroscopy users (n = 35), 28 (66%) agreed that a multicenter study is warranted

    Diabetes mellitus affects >20 million people in the United States each year, and >4000 new cases are diagnosed daily. This study assessed the prescription of statin medications in the ambulatory setting in US diabetic patients. We used data from the 2002 through 2004 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey. All ambulatory medical visits associated with a diabetes diagnosis by the International Classification of Diseases, Ninth Revision, Clinical Modification were included. Prescriptions for statin medications were determined by searching each ambulatory visit for relevant drug names (trade and generic). Demographic characteristics were assessed, including survey year, sex, age group, race, ethnicity, payment type, region of the country, and physician's specialty and degree. Analyses used sample weights to calculate national estimates. From 2002 to 2004, 10,046 (unweighted) ambulatory visits were made by diabetic patients, representing a weighted national estimate of approximately 153 million visits. A statin prescription was associated with 21.1% of all diabetic visits and 14.1% of those without a hyperlipidemia-related diagnosis. Diabetic men were more likely than diabetic women to be given a prescription for a statin (odds ratio [OR], 1.38; 95% CI, 1.09-1.73). Compared with diabetic patients treated in 2002, those treated in 2003 and 2004 were more likely to be prescribed statin therapy (2003 OR, 1.51; 95% CI, 1.02-2.24; 2004 OR, 1.48; 95% CI, 1.03-2.15). Compared with diabetic patients aged 45 to 64 years, those in younger age groups were less likely to be given a statin prescription (1-24 years OR, 0.10; 95% CI, 0.01-0.84; 25-44 years OR, 0.48; 95% CI, 0.31-0.74), and those aged 65 to 74 years were more likely to be given a statin (OR, 1.38; 95% CI, 1.01-1.90). No differences were noted for diabetic patients aged > or = 75 years. From 2002 through 2004, medical visits by diabetic patients in the United States

    Full Text Available Abstract Background Little evidence exists to guide treatment of alopecia areata (AA. The current practices in treatment of children compared to adults and of progressive stages of hair loss are unknown. The objective of this study was to examine the current practices of southeastern United States dermatologists for the treatment of AA. Methods Dermatologists were sent anonymous questionnaires regarding their treatment practices by mail. Respondents' frequencies of treatment in children compared to adults and in patchy hair loss compared to widespread hair loss were compared with Wilcoxon signed-ranks tests and Friedman tests. As a secondary source, the National Alopecia Areata Registry (NAAR database was analyzed for patients' treatment histories. Results Survey results suggested that dermatologists recommend treatment less frequently for children than adults and for more advanced hair loss. NAAR data confirmed that offering no treatment for AA is relatively common. Conclusion Dermatologists' treatment of AA is inconsistent. A stronger evidence base will provide more consistent treatment options.

    To identify similarities and differences in the behavioral profile of children with Williams syndrome from Spain (n = 53) and the United States (n = 145), we asked parents of 6- to 14-year-olds with Williams syndrome to complete the Child Behavior Checklist 6-18. The distribution of raw scores was significantly higher for the Spanish sample than the American sample for all of the higher-order factors and half of both the empirically based and Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales. In contrast, analyses based on country-specific T-scores indicated that the distribution for the Spanish sample was significantly higher than for the American sample only on the Social Problems scale. No gender differences were found. Genetic and cultural influences on children's behavior and cultural influences on parental ratings of behavior are discussed.

    Full Text Available The study aimed to assess factors associated with self-medication (SM among expatriate high school students of United Arab Emirates using a validated questionnaire. Most common reasons for self-medication in 324 participating students were: presence of mild illness and previous experiences. High risk practices like altering the dose, discontinuation of medication and self-medication without adult guidance were observed. The likelihood of SM was 4.9 times (95%C.I.: 2.0-12.2 in students not utilizing private healthcare services than those who were utilizing these services. Increased efforts are needed to prevent the risks of self-medication in adolescents through healthcare education for both parents and adolescents.

    The elastic scattering p( 6 He, 6 He)p and charge exchange reaction p( 6 He, 6 Li)n have been measured in reverse kinematics with a secondary 6 He beam. The angular distributions for these reactions were obtained. In the case of the charge exchange reaction, the ratio of the cross section for the Gamow-Teller transition to the ground state, and for the Fermi transition to the isobaric analog state is a measure of the relative strength of the two components of the exchange interaction. This ratio is found compatible with existing systematics for stable T=1 nuclei, and no clear signature of a halo structure was found in the present data. (author)

    Full Text Available Abstract Background Fibromyalgia (FM is characterized by chronic, widespread pain, fatigue, and other symptoms; yet few studies have comprehensively assessed its humanistic burden. This observational study evaluates the impact of FM severity on patients' symptoms, health-related quality of life (HRQoL, and productivity in the United States. Methods 203 FM subjects were recruited from 20 physician offices. Subjects completed a questionnaire including the EuroQol 5D (EQ-5D, Fibromyalgia Impact Questionnaire (FIQ, Multidimensional Assessment of Fatigue (MAF, Medical Outcomes Study Sleep Scale (MOS-SS, and Hospital Anxiety and Depression Scale (HADS and questions about demographics, pain and other symptoms, HRQoL and productivity. FIQ total scores were used to define FM severity, with 0- Results Mean (SD age was 47.9 (10.9; 95% were female. Most (92% were prescribed medication for FM; 24% and 66% reported moderate and severe FM, respectively.

    Full Text Available This study explored the associations between health awareness, health behaviour, subjective health status, and satisfaction of students with their educational experience as independent variables and three outcomes of educational achievement as dependent variables. We undertook two simultaneous cross-sectional surveys among students from one University in the UK during 2008−2009. The first survey was a general health survey; the second survey measured students’ satisfaction with different aspects of their learning and teaching experience. Students’ registration numbers linked the responses of both questionnaires together, and subsequently linked the questionnaires to the university database to import the grades that students actually achieved in their studies. Generally, students (N = 380 exhibited average medium to high satisfaction with their educational experiences. Students’ satisfaction with their educational experiences was not associated with any of the three indicators of educational achievement (actual module mark; perceived own performance; importance of achieving good grades. The associations of educational satisfaction, health, health behaviours, heath complaints and financial parameters with the three outcomes of educational achievement did not differ between male and female students. Each of the health, health behaviours, health complaints and financial parameters were selectively associated with only some but not all three indicators of student educational achievement. We conclude that the findings support a conceptual framework suggesting reciprocal relationships between health, health behaviour and educational achievement. Comprehensive health promotion programmes may have the potential to influence relevant predictors of educational achievement in university students.

    Tobacco advertising, promotion, and sponsorship (TAPS) bans are effective and are increasingly being implemented in a number of venues and countries, yet the state of TAPS in airports and their effect on airport smoking behavior is unknown. The objective of this study was to evaluate the presence of TAPS in airports across Europe and the US, and to begin to examine the relationship between TAPS and smoking behaviors in airports. We used a cross-sectional study design to observe 21 airports in Europe (11) and the US (10). Data collectors observed points of sale for tobacco products, types of products sold, advertisements and promotions, and branding or logos that appeared in the airport. Tobacco products were sold in 95% of all airports, with significantly more sales in Europe than the US. Advertisements appeared mostly in post-security areas; however, airports with advertisements in pre-security areas had significantly more smokers observed outdoors than airports without advertisements in pre-security areas. Tobacco branding appeared in designated smoking rooms as well as on non-tobacco products in duty free shops. TAPS are widespread in airports in Europe and the US and might be associated with outdoor smoking, though further research is needed to better understand any relationship between the two. This study adds to a growing body of research on tobacco control in air transit and related issues. As smoke-free policies advance, they should include comprehensive TAPS bans that extend to airport facilities.

    Suboptimal breastfeeding duration and exclusivity rates are a public health concern. Therefore, there is a need for identifying effective tools for use in interventions targeting specific barriers to optimal breastfeeding outcomes. Research aim: This study aimed to assess the relationship between acceptance of remote lactation consultation using videoconferencing and (a) maternal demographic factors, (b) technology acceptance subscales, (c) maternal learning style preferences, and (d) other potentially explanatory maternal factors. This was a cross-sectional, online study. English-speaking mothers of at least 18 years of age, with an infant age 4 months or younger, and who reported initiating breastfeeding were eligible to participate. Mothers were recruited from 27 randomly selected states. One hundred one mothers completed the survey, resulting in a response rate of 71%. The main outcome was acceptance of videoconferencing use for lactation consultation. No significant differences were found in acceptance by maternal demographic factors or learning style preferences. Acceptance was significantly related to perceived ease of use ( r = .680, p extrinsic motivation ( r = .774, p intrinsic motivation ( r = .689, p extrinsic motivation and maternal age remained in the final regression model ( R 2 = .616, p extrinsic motivation was positively associated with acceptance, maternal age was inversely related. This sample of mothers indicated general acceptance of videoconferencing for lactation consultation, with younger mothers and those perceiving it to be more useful demonstrating greater acceptance.

    Before 2007, immigrants and refugees bound for the United States were screened for tuberculosis (TB) by a smear-based algorithm that could not diagnose smear-negative/culture-positive TB. In 2007, the Centers for Disease Control and Prevention implemented a culture-based algorithm. To evaluate the effect of the culture-based algorithm on preventing the importation of TB to the United States by immigrants and refugees from foreign countries. Population-based, cross-sectional study. Panel physician sites for overseas medical examination. Immigrants and refugees with TB. Comparison of the increase of smear-negative/culture-positive TB cases diagnosed overseas among immigrants and refugees by the culture-based algorithm with the decline of reported cases among foreign-born persons within 1 year after arrival in the United States from 2007 to 2012. Of the 3 212 421 arrivals of immigrants and refugees from 2007 to 2012, a total of 1 650 961 (51.4%) were screened by the smear-based algorithm and 1 561 460 (48.6%) were screened by the culture-based algorithm. Among the 4032 TB cases diagnosed by the culture-based algorithm, 2195 (54.4%) were smear-negative/culture-positive. Before implementation (2002 to 2006), the annual number of reported cases among foreign-born persons within 1 year after arrival was relatively constant (range, 1424 to 1626 cases; mean, 1504 cases) but decreased from 1511 to 940 cases during implementation (2007 to 2012). During the same period, the annual number of smear-negative/culture-positive TB cases diagnosed overseas among immigrants and refugees bound for the United States by the culture-based algorithm increased from 4 to 629. This analysis did not control for the decline in new arrivals of nonimmigrant visitors to the United States and the decrease of incidence of TB in their countries of origin. Implementation of the culture-based algorithm may have substantially reduced the incidence of TB among newly arrived, foreign-born persons in

    2007-02-01

    In order to determine the prevalence and risk factors for necrotic enteritis in broilers, a cross-sectional survey was conducted among 857 farms, rearing broilers for nine UK poultry companies. The main data collection tool was a postal questionnaire directed at farm managers. Additional information on disease occurrence on the farm was collected from veterinary postmortem reports. The response rate to the questionnaire was 75%, ranging from 54% to 90% within companies. During 2001, 32.8% of the respondents indicated that they had observed a case of necrotic enteritis (95% confidence interval, 29.1 to 36.8) in at least one flock. The disease was most often reported during the months October to February. The point prevalence (necrotic enteritis occurrence in the most recently reared flock) reported by farm managers was 12.3% (95% confidence interval, 9.8 to 15.2). Multilevel logistic regression was performed with the poultry company as the random effect, using the occurrence of necrotic enteritis in the farm's most recently reared flock as the dependent variable. Strong associations were found between the outcome variable and the occurrence of wet litter (odds ratio, 2.39; 95% confidence interval, 1.27 to 4.52; P = 0.007) and coccidiosis (odds ratio, 4.68; 95% confidence interval, 1.74 to 12.55; P = 0.002). In addition, the use of ammonia as a disinfectant for coccidial oocysts appeared to be an independent risk factor (odds ratio, 3.44; 95% confidence interval, 1.53 to 7.71; P = 0.003). Finally, the positive association between the use of plasterboard walls in poultry houses and the occurrence of necrotic enteritis might point to an important role of cleaning and disinfection in the epidemiology of this disease (odds ratio, 3.72; 1.38 to 10.00; P = 0.009).

    Research in the area of cultural response pattern on questionnaires in the oncological setting and direct cross-cultural comparisons are lacking. This study examined response pattern in the reporting of depressive symptoms in Chinese and US women with breast cancer. We hypothesized that Chinese women are less likely to endorse positive affect items compared to their US counterparts. Additionally, we explored cultural differences in the association between positive affect and QOL. Secondary analyses of baseline assessments of two mind-body intervention studies for women with breast cancer undergoing radiotherapy in the USA (N = 62) and China (N = 97) are presented. All participants completed measures of depressive symptoms (CES-D) and cancer-specific QOL (FACT-B). We examined cultural differences on positive and negative affect items on the CES-D. Controlling for demographic factors, ANCOVA revealed a significant cultural difference in positive (F = 7.99, p = 0.005) but not negative affect (p = 0.82) with Chinese women reporting lower positive affect compared to US women (Chinese = 6.97 vs. US = 8.31). There was also a significant cultural difference (F = 3.94, p = 0.03) in the association between positive affect and QOL so that lower positive affect was more strongly associated with worse emotional well-being in Chinese (beta = 0.57, p cultures to ascertain effective delivery of clinical services to those in need.

    Full Text Available The increased representation of minority students on the campuses of predominantly White universities in the United States presents increased opportunities for intercultural contact. Studying dating experiences across racial and ethnic lines has been used to determine the existence of a post-racial America. While most previous research has examined general racial/ethnic and gender differences in intercultural college dating experiences, this study analyzes precollege and college-going friendship diversity and skin tone as factors accounting for romantic distance between racial/ethnic groups among a recent cohort of college students. Hierarchical linear modeling analyses were conducted on a 4-year longitudinal sample of 2804 undergraduate students from 24 colleges and universities. Results confirm that White students continue to be the group most likely to engage in intragroup dating relationships, Latino/a students were the most likely to date interculturally, and that Black men were significantly more likely to date interculturally than Black women. For Black students there were significant within group differences in intercultural dating based on skin tone.

    It appears that Sweden and the United States may be a study in contrasts regarding the sanction and use of corporal punishment on children. A 1979 study of American parents noted that 81% of them employed corporal punishment with children. A different study done in Sweden in 1978 noted that only 26% of parents used corporal punishment with children. What points to the differences in these parenting patterns within the two countries? In addition, a 1977 U.S. Supreme Court case entitled Ingraham vs. Wright ruled that "schools are empowered to carry out corporal punishment." This court case involved two high school boys in Florida who had been repeatedly struck with wooden paddles. In contrast, Sweden had statutes which prohibited corporal punishment of children in their secondary schools as early as the 1920s. In 1957, the country passed a law which defined corporal punishment as unacceptable for small children in the schools. Then, in 1979, the Swedish government passed a statute prohibiting corporal punishment by parents. Are there differences in the way the two countries view law and its uses? Or, do the cultures sanction violence in general or just violence against children in different ways? This article examines some of the similarities and differences found in American and Swedish treatment of children and proposes what appear to be extreme differences in the way the countries and their people approach corporal punishment.

    To determine patterns of United Arab Emirates (UAE) citizen herbal medicine taking. Questionnaire survey of UAE citizens attending a primary healthcare clinic in Abu Dhabi. Three hundred and thirty surveys were analysed. Seventy-six per cent (250/330) had previously used herbal products, and of these 38% (94/248) were currently taking at least one herb. In total, 65 different herbs were being taken to treat 48 conditions. Respondents overwhelmingly felt herbal medicines were safe, yet 27 people reported experiencing an adverse drug reaction. Causality was not established because of multiple herbal use and a propensity for concurrent herbal and Western medicine taking. Respondents relied heavily on family and friends for advice and bought herbs from a 'condimental shop' (local herbal seller/healer). Despite high herbal use, respondents still preferred Western medicine to treat chronic diseases. This study has shown that UAE nationals have faith and confidence in herbal medicines and are consequently high users of them despite the country's progressive adoption of Western approaches to health care.

    Full Text Available A survey of 100 women in the south of London, United Kingdom (UK compared exercise barrier intensities between non-exercising younger (20-27 years and older (28-35 years adult women; and examined childcare duties as perceived barriers to exercise. Perceived barriers to exercise were examined using an Exercise Benefits/Barriers Scale (EBBS comprising four subscales (exercise milieu; time expenditure; physical exertion; family discouragement. Participants’ number of children was also noted. Non-exercising older women reported significantly higher total exercise barriers, as well as across three barrier subscales: exercise milieu, time expenditure, and family discouragement. For both age groups, significant correlation existed between number of children and women’s total exercise barrier scores. Number of children explained »25% and »30% of the variance of younger and older women’s total barrier scores respectively. For both women groups, the strongest correlation between exercise barrier and number of children was for the time expenditure subscale. Broad grouping of 20-35 year old non-exercising women does not reflect a homogenous sample. Age categories employing narrower age brackets are recommended. Issues surrounding family responsibilities e.g. childcare duties may be shared between these groups and require further research and policy attention.

    In this study, the alcohol use behaviors and associated factors of US and Sri Lankan undergraduates were compared. A sample of 515 US (63% female) and 583 Sri Lankan (54% female) undergraduates were surveyed using a self-administered, anonymous questionnaire. Significant variations by gender and country existed. In the US sample, 89.5% of males and 76.5% of females were current alcohol users; in the Sri Lankan sample, 30.5% of males and 3.5% of females were current alcohol users. For both sexes, the reported mean monthly consumption rate (units/month) was higher in the US sample (male=25.6, female=16.4) compared to that of the Sri Lankan sample (male=8.1, female=8.4). In the US sample, the mean alcohol consumption rates reported were higher in first-year undergraduates compared to undergraduates in subsequent years of study. In contrast, mean alcohol consumption was lower in junior undergraduates compared to senior undergraduates in the Sri Lankan sample. Living arrangements (on-campus vs off-campus) seemed to be unrelated to alcohol use in the US undergraduates, but living in off-campus residences seems to be a protective factor of alcohol use for the Sri Lankan undergraduates. Those implementing prevention strategies should seriously consider these culture-specific drinking habits and motives, and other factors, such as gender, when formulating undergraduate alcohol-control interventions.

    We explore marital and depression trajectories over time for men and women, and distinguish between mood and somatic depression across contexts. We use longitudinal data from 2002 to 2013 from the United States, England, Europe, Korea, and China to explore depression among individuals married at baseline and follow their trajectories into widowhood with married as the reference group. We use random effects models to estimate these trajectories using the Center for Epidemiologic Studies Depression Scale (CES-D) or EURO-D scales for men and women. Depression peaks within the first year of widowhood for men and women, but women recover to levels comparable to married counterparts in all countries. Men sustain high levels of depression even 6-10 years post-widowhood everywhere except Europe. Widowed women have higher somatic depression compared to men, who have higher mood depression. Family plays differential roles in mediating depression across countries. Our research shows the complex global relationship between widowhood and depression. Studies that do not compare depression trajectories over time may make incorrect inferences about the persistence of depression by gender and country. Interventions should target different components of depression: mood-related symptoms for men and somatic-related symptoms for women for most effective recovery. © The Author 2017.

    Objective : To assess the correlates of the high risk sexual behaviors of Polish migrants in the United Kingdom (UK) after 2004, and to compare such behaviors before/after immigration. Methods : In 2013, a cross-sectional study was conducted through the use of a Computer-assisted web interviewing surveying technique with the use of a self-administered questionnaire. Results : Among 408 respondents (56.9% women), with a median age of 32 years, significantly more admitted to having unprotected sexual contact with a casual partner while in the UK ( p self-esteem, were predictors of unprotected sex. A total of 19.6% of the respondents admitted to having been tested while in Poland, a lower ( p self-esteem, staying in the UK for less than two years. The results point to strengthening strategies which help reduce high risk sexual behavior among Polish migrants, and to introduce interventions to promote an awareness of HIV sero-status.

    To measure the extent, determinants and results of bypassing local primary care clinics for childbirth among women in rural parts of the United Republic of Tanzania. Women were selected in 2012 to complete a structured interview from a full census of all 30076 households in clinic catchment areas in Pwani region. Eligibility was limited to those who had delivered between 6 weeks and 1 year before the interview, were at least 15 years old and lived within the catchment areas. Demographic and delivery care information and opinions on the quality of obstetric care were collected through interviews. Clinic characteristics were collected from staff via questionnaires. Determinants of bypassing (i.e. delivery of the youngest child at a health centre or hospital without provider referral) were analysed using multivariate logistic regression. Bypasser and non-bypasser birth experiences were compared in bivariate analyses. Of 3019 eligible women interviewed (93% response rate), 71.0% (2144) delivered in a health facility; 41.8% (794) were bypassers. Bypassing likelihood increased with primiparity (odds ratio, OR: 2.5; 95% confidence interval, CI: 1.9-3.3) and perceived poor quality at clinics (OR: 1.3; 95% CI: 1.0-1.7) and decreased if clinics recently underwent renovations (OR: 0.39; 95% CI: 0.18-0.84) and/or performed ≥ 4 obstetric signal functions (OR: 0.19; 95% CI: 0.08-0.41). Bypassers reported better quality of care on six of seven quality of care measures. Many pregnant women, especially first-time mothers, choose to bypass local primary care clinics for childbirth. Perceived poor quality of care at clinics was an important reason for bypassing. Primary care is failing to meet the obstetric needs of many women in this rural, low-income setting.

    The Patient Protection and Affordable Care Act (ACA) galvanised debate in the United States (US) over universal health coverage. Comparison with countries providing universal coverage may illustrate whether the ACA can improve health outcomes and reduce disparities. We aimed to compare quality and disparities in hypertension management by socio-economic position in the US and England, the latter of which has universal health care. We used data from the Health and Retirement Survey in the US, and the English Longitudinal Study for Aging from England, including non-Hispanic White respondents aged 50-64 years (US market-based v NHS) and >65 years (US-Medicare v NHS) with diagnosed hypertension. We compared blood pressure control to clinical guideline (140/90 mmHg) and audit (150/90 mmHg) targets; mean systolic and diastolic blood pressure and antihypertensive prescribing, and disparities in each by educational attainment, income and wealth, using regression models. There were no significant differences in aggregate achievement of clinical targets aged 50 to 65 years (US market-based vs. NHS--62.3% vs. 61.3% [p = 0.835]). There was, however, greater control in the US in patients aged 65 years and over (US Medicare vs. NHS--53.5% vs. 58.2% [p = 0.043]). England had no significant socioeconomic disparity in blood pressure control (60.9% vs. 63.5% [p = 0.588], high and low wealth aged ≥65 years). The US had socioeconomic differences in the 50-64 years group (71.7% vs. 55.2% [p = 0.003], high and low wealth); these were attenuated but not abolished in Medicare beneficiaries. Moves towards universal health coverage in the US may reduce disparities in hypertension management. The current situation, providing universal coverage for residents aged 65 years and over, may not be sufficient for equality in care.

    Increasing numbers of minor surgical procedures are being performed in the community. In the UK, general practitioners (family medicine physicians) with a specialist interest (GPwSI) in surgery frequently undertake them. This shift has caused decreases in available cases for junior surgeons to gain and consolidate operative skills. This study evaluated GPwSI's case-load, procedural training and perceptions of offering formalised operative training experience to surgical trainees. Prospective, questionnaire-based cross-sectional study. A novel, 13-item, self-administered questionnaire was distributed to members of the Association of Surgeons in Primary Care (ASPC). A total 113 of 120 ASPC members completed the questionnaire, representing a 94% response rate. Respondents were general practitioners practising or intending to practice surgery in the community. Respondents performed a mean of 38 (range 5-150) surgical procedures per month in primary care. 37% (42/113) of respondents had previously been awarded Membership or Fellowship of a Surgical Royal College; 22% (25/113) had completed a surgical certificate or diploma or undertaken a course of less than 1 year duration. 41% (46/113) had no formal British surgical qualifications. All respondents believed that surgical training in primary care could be valuable for surgical trainees, and the majority (71/113, 63%) felt that both general practice and surgical trainees could benefit equally from such training. There is a significant volume of surgical procedures being undertaken in the community by general practitioners, with the capacity and appetite for training of prospective surgeons in this setting, providing appropriate standards are achieved and maintained, commensurate with current standards in secondary care. Surgical experience and training of GPwSI's in surgery is highly varied, and does not yet benefit from the quality assurance secondary care surgical training in the UK undergoes.

    Full Text Available Background: Adverse Drug Reactions (ADRs are a major public health problem. Prompt reporting of suspected ADRs is fundamental in the post-marketing surveillance of medicines and helps in ensuring medicine safety. However, fewer ADRs are reported in general and in particular by community pharmacists. There is limited knowledge about the factors which are preventing community pharmacists in the UK from reporting an ADR. Objectives: To identify the barriers to ADR reporting among community pharmacists practicing in the UK. Methods: A cross sectional study using a 25-items questionnaire (both online and paper based including 10 barriers to ADR reporting was conducted from 1st April 2012 to September 2012. Community pharmacists practicing in the West Midlands, UK, were approached for the participation in this study. Chi-Square and regression were applied to identify covariates for the barriers to ADR reporting. A significant value of 0.05 was assigned for analysis. Results: Of the 230 invited community pharmacists, 138 pharmacists responded (response rate 60%. The median age of respondents was 31 years. All pharmacists reported that they would report both serious and mild ADRs from drugs with black triangle among children as well as adults. About 95% (n=131 of the pharmacists were familiar with the paper based ADR reporting system. Store-based pharmacists were more likely to be more confident about which ADRs to report [0.680, 95% Confidence Interval 0.43-3.59]. Lack of time 46.4% (n=64, and pharmacists perception that ADR is not serious enough to report (65.2%; n=90 were identified as barriers to ADR reporting. Majority 63.0% (n=87 of the pharmacists identified training and information about what to report and access to Information Technology (IT (For example access to internet connection 61.6% (n=85 as facilitators to ADR reporting process. Conclusion: Lack of time and ADRs considered not serious enough by pharmacists to report were barriers to ADR

    In 2005, physician and nursing leaders at Brigham and Women's Hospital initiated structured interprofessional rounds (SIPRs) on the labor and delivery (L&D) suite to improve team communication. We performed a cross-sectional analysis of providers' perceptions of SIPRs and their effectiveness in improving teamwork. We hypothesized that on average, providers would perceive SIPRs as being effective in promoting teamwork, but ratings would differ among professional groups. After a factor analysis and internal consistency assessment, a 19-item paper-based questionnaire was used to evaluate providers' perceptions using a 5-point Likert scale. Respondents included L&D nurses, midwives, obstetricians, and anesthesiologists who participate in SIPRs. The primary aim was to evaluate the providers' perceptions of SIPRs and their association with professional roles. The outcome was total response score for each provider, ranging from 19 to 95; perception of SIPRs as being effective in promoting teamwork was defined as having a total response score of >66.5 (mean score, >3.5 per question). A univariable linear regression model was performed, followed by a multivariable analysis adjusting for predictors that modified the outcome; predictors included years of professional practice, years of experience on the L&D suite, number of clinical work hours worked weekly, and principal shift assignment among nurses. The associations between these predictors and providers' perceptions were assessed as a secondary aim. A total of 234 practitioners responded (100% response rate). The mean total response score (SD) for all providers was 73.3 (9.5). After multivariable adjustment, the mean total response scores were significantly higher for obstetric providers than for anesthesia (Δ mean, 6.5, 95% CI, 0.3, 12.7 P = .036) and midwifery (Δ mean, 12.5, 95% CI, 2.0, 23.0, P = .009) providers. Providers scored significantly lower if they worked >60 clinical hours per week compared with ≤20 (

    Full Text Available Abstract Background Physical activity is essential for health; walking is the easiest way to incorporate activity into everyday life. Previous studies report positive associations between neighbourhood walkability and walking but most focused on cities in North America and Australasia. Urban form with respect to street connectivity, residential density and land use mix—common components of walkability indices—differs in European cities. The objective of this study was to develop a walkability index for London and test the index using walking data from the Whitehall II Study.  Methods A neighbourhood walkability index for London was constructed, comprising factors associated with walking behaviours: residential dwelling density, street connectivity and land use mix. Three models were produced that differed in the land uses included. Neighbourhoods were operationalised at three levels of administrative geography: (i 21,140 output areas, (ii 633 wards and (iii 33 local authorities. A neighbourhood walkability score was assigned to each London-dwelling Whitehall II Study participant (2003–04, N = 3020, mean ± SD age = 61.0 years ± 6.0 based on residential postcode. The effect of changing the model specification and the units of enumeration on spatial variation in walkability was examined. Results There was a radial decay in walkability from the centre to the periphery of London. There was high inter-model correlation in walkability scores for any given neighbourhood operationalisation (0.92–0.98, and moderate-high correlation between neighbourhood operationalisations for any given model (0.39–0.70. After adjustment for individual level factors and area deprivation, individuals in the most walkable neighbourhoods operationalised as wards were more likely to walk >6 h/week (OR = 1.4; 95 % CI: 1.1–1.9 than those in the least walkable. Conclusions Walkability was associated with walking time in adults. This

    Cross-cultural differences in attitudes toward schizophrenia are suggested, while no studies have compared such attitudes between the United States and Japan. In our previous study in Japan (Hori et al., 2011), 197 subjects in the general population and 112 physicians (excluding psychiatrists) enrolled in a web-based survey using an Internet-based questionnaire format. Utilizing the identical web-based survey method in the United States, the present study enrolled 172 subjects in the general population and 45 physicians. Participants' attitudes toward schizophrenia were assessed with the English version of the 18-item questionnaire used in our previous Japanese survey. Using exploratory factor analysis, we identified four factors labeled "social distance," "belief of dangerousness," "underestimation of patients' abilities," and "skepticism regarding treatment." The two-way multivariate analysis of covariance on the four factors, with country and occupation as the between-subject factors and with potentially confounding demographic variables as the covariates, revealed that the general population in the US scored significantly lower than the Japanese counterparts on the factors "social distance" and "skepticism regarding treatment" and higher on "underestimation of patients' abilities." Our results suggest that culture may have an important role in shaping attitudes toward mental illness. Anti-stigma campaigns that target culture-specific biases are considered important.

    The objective of this paper is to perform a cross-cultural comparison of gambling disorder (GD) due to electronic gaming machines (EGM), a form of gambling that may have a high addictive potential. Our goal is to investigate two treatment-seeking samples of adults collected in Brazil and the United States, countries with different socio-cultural backgrounds. This comparison may lead to a better understanding of cultural influences on GD. The total studied sample involved 733 treatment-seeking subjects: 353 men and 380 women (average age=45.80, standard deviation ±10.9). The Brazilian sample had 517 individuals and the American sample 216. Subjects were recruited by analogous strategies. We found that the Brazilian sample was younger, predominantly male, less likely to be Caucasian, more likely to be partnered, tended to have a faster progression from recreational gambling to GD, and were more likely to endorse chasing losses. This study demonstrated that there are significant differences between treatment-seeking samples of adults presenting GD due to EGM in Brazil and in the United States. These findings suggest that cultural aspects may have a relevant role in GD due to EGM. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    To evaluate the geographic distribution of assisted reproductive technology (ART) clinics and the number of ART clinics within U.S. Census metropolitan areas and to estimate the number of reproductive-age women who have geographic access to ART services in the United States. A population-based cross-sectional study. Not applicable. None. None. Number of U.S. reproductive-age women living in areas with no ART clinic, a single ART clinic, or more than one ART clinic. There were 510 ART clinics in the United States in 2009-2013. Multiple ART clinics were present in 76 metropolitan areas (median population of 1.45 million people), where a total of 442 clinics were located. A single ART clinic was present in 68 metropolitan areas (median population of 454,000 people). Among U.S. reproductive-age women in 2010, 38.1 million (60.4% of the U.S. population) lived in an area with multiple ART clinics, 6.8 million (10.8% of the U.S. population) lived in an area with a single clinic, and 18.2 million (28.8% of the U.S. population) lived in an area (metropolitan and nonmetropolitan) with no ART clinics. Nearby geographic access to ART services is limited or absent for more than 25 million reproductive-age women (39.6% of the U.S. population) in the United States. This population estimate should spur continued policy and technological progress to increase access to ART services. Copyright © 2017 American Society for Reproductive Medicine.

    Epidemiological studies show wide variability in the occurrence of cannabis smoking and related disorders across countries. This study aims to estimate cross-national variation in cannabis users' experience of clinically significant cannabis-related problems in three countries of the Americas, with a focus on cannabis users who may have tried alcohol or tobacco, but who have not used cocaine, heroin, LSD, or other internationally regulated drugs. Data are from the World Mental Health Surveys Initiative and the National Latino and Asian American Study, with probability samples in Mexico (n = 4426), Colombia (n = 5,782) and the United States (USA; n = 8,228). The samples included 212 'cannabis only' users in Mexico, 260 in Colombia and 1,724 in the USA. Conditional GLM with GEE and 'exact' methods were used to estimate variation in the occurrence of clinically significant problems in cannabis only (CO) users across these surveyed populations. The experience of cannabis-related problems was quite infrequent among CO users in these countries, with weighted frequencies ranging from 1% to 5% across survey populations, and with no appreciable cross-national variation in general. CO users in Colombia proved to be an exception. As compared to CO users in the USA, the Colombia smokers were more likely to have experienced cannabis-associated 'social problems' (odds ratio, OR = 3.0; 95% CI = 1.4, 6.3; p = 0.004) and 'legal problems' (OR = 9.7; 95% CI = 2.7, 35.2; p = 0.001). This study's most remarkable finding may be the similarity in occurrence of cannabis-related problems in this cross-national comparison within the Americas. Wide cross-national variations in estimated population-level cumulative incidence of cannabis use disorders may be traced to large differences in cannabis smoking prevalence, rather than qualitative differences in cannabis experiences. More research is needed to identify conditions that might make cannabis-related social and legal problems more

    To investigate the cross-cultural validity of the Orthotics and Prosthetics Users' Survey (OPUS), to evaluate differential item functioning (DIF) related to country, sex, age, amputation level, and amputated side (unilateral, bilateral), and to determine known-group validity of the OPUS. Survey. Outpatient clinics. The sample (N=321) consisted of Swedish (n=195) and U.S. (n=126) adults using lower-limb prostheses. Not applicable. Four OPUS modules were used: lower extremity functional status, client satisfaction with device (CSD), client satisfaction with services (CSS), and health-related quality of life. Rasch analysis was used to calculate measures for persons and items. The cross-cultural validity was satisfactory. Many items demonstrated DIF related to country and demographic characteristics, but the impact on mean person measures was negligible. The rating scales of CSD and CSS needed adjustments, and the unidimensionality of CSD and CSS was weak. The differences between the mean measures of known patient groups were statistically significant for 2 out of 6 comparisons. This study supports the validity of OPUS measure comparisons between Sweden and the United States and between subgroups with different demographic characteristics. Some of the country-related DIF may reflect the different health care financing systems. The findings demonstrate that the OPUS can discriminate between certain patient groups. The results also challenge some of our preconceptions about persons with bilateral amputation, indicating that we might know these persons less well than we think.

    The Knowledge about Older Patients-Quiz (KOP-Q) is designed as a unidimensional scale measuring knowledge of hospital nurses about older patients. Furthermore, the KOP-Q measures a second unidimensional construct, certainty of hospital nurses about their knowledge. The KOP-Q is developed and validated in the Netherlands. Whether the KOP-Q can be used in other countries is unknown given the cultural and language differences. Investigate the level of measurement invariance of the KOP-Q between the Netherlands and United States of America (USA). A multicenter international cross-sectional design. Four general hospitals in the Netherlands and four general hospitals in the USA. Nurses from the Netherlands (n=201) and the USA (n=130) were invited to participate by email from the ward manager, distributing flyers and present messages on the online hospital communication boards. Questions of the KOP-Q were completed online. The level of measurement invariance (configural, metric or scalar invariance) across countries was tested by running increasingly constrained structural equation models, and testing whether these models fitted the data. Both the knowledge and certainty construct of the KOP-Q proved unidimensional in the Netherlands and USA sample. Test results of the measurement invariance across the Netherlands and USA indicated a stable, partial scalar invariance (15 items full scalar invariance) for the knowledge items and full scalar invariance for the certainty items. The KOP-Q shows to function uniformly across both language groups and can therefore be used to assess nurses' knowledge and their certainty about this knowledge which can be important for educational and/or quality improvement programs in the USA. Furthermore, the KOP-Q is suitable to make comparisons between the Netherlands and the USA using latent variable models. Before the KOP-Q can be used in other countries, cross-cultural tests should again be performed. Copyright © 2017 Elsevier Ltd. All

    ABSTRACT Objective: To translate the Perme Intensive Care Unit Mobility Score and the ICU Mobility Scale (IMS) into Portuguese, creating versions that are cross-culturally adapted for use in Brazil, and to determine the interobserver agreement and reliability for both versions. Methods: The processes of translation and cross-cultural validation consisted in the following: preparation, translation, reconciliation, synthesis, back-translation, review, approval, and pre-test. The Portuguese-language versions of both instruments were then used by two researchers to evaluate critically ill ICU patients. Weighted kappa statistics and Bland-Altman plots were used in order to verify interobserver agreement for the two instruments. In each of the domains of the instruments, interobserver reliability was evaluated with Cronbach's alpha coefficient. The correlation between the instruments was assessed by Spearman's correlation test. Results: The study sample comprised 103 patients-56 (54%) of whom were male-with a mean age of 52 ± 18 years. The main reason for ICU admission (in 44%) was respiratory failure. Both instruments showed excellent interobserver agreement (κ > 0.90) and reliability (α > 0.90) in all domains. Interobserver bias was low for the IMS and the Perme Score (−0.048 ± 0.350 and −0.06 ± 0.73, respectively). The 95% CIs for the same instruments ranged from −0.73 to 0.64 and −1.50 to 1.36, respectively. There was also a strong positive correlation between the two instruments (r = 0.941; p < 0.001). Conclusions: In their versions adapted for use in Brazil, both instruments showed high interobserver agreement and reliability. PMID:28117473

    The negative health effects of cigarette smoking and HIV infection are synergistic. To compare the prevalence of current cigarette smoking and smoking cessation between adults with HIV receiving medical care and adults in the general population. Nationally representative cross-sectional surveys. United States. 4217 adults with HIV who participated in the Medical Monitoring Project and 27 731 U.S. adults who participated in the National Health Interview Survey in 2009. The main exposure was cigarette smoking. The outcome measures were weighted prevalence of cigarette smoking and quit ratio (ratio of former smokers to the sum of former and current smokers). Of the estimated 419 945 adults with HIV receiving medical care, 42.4% (95% CI, 39.7% to 45.1%) were current cigarette smokers, 20.3% (CI, 18.6% to 22.1%) were former smokers, and 37.3% (CI, 34.9% to 39.6%) had never smoked. Compared with the U.S. adult population, in which an estimated 20.6% of adults smoked cigarettes in 2009, adults with HIV were nearly twice as likely to smoke (adjusted prevalence difference, 17.0 percentage points [CI, 14.0 to 20.1 percentage points]) but were less likely to quit smoking (quit ratio, 32.4% vs. 51.7%). Among adults with HIV, factors independently associated with greater smoking prevalence were older age, non-Hispanic white or non-Hispanic black race, lower educational level, poverty, homelessness, incarceration, substance use, binge alcohol use, depression, and not achieving a suppressed HIV viral load. Cross-sectional design with some generalizability limitations. Adults with HIV were more likely to smoke and less likely to quit smoking than the general adult population. Tobacco screening and cessation strategies are important considerations as part of routine HIV care.

    Seasonal influenza, though mostly self-limited in the healthy adult, may lead to severe disease and/or complications in subpopulations. Annual influenza vaccination is available in many countries with coverage goals rarely being met. We conducted a cross-sectional study of influenza vaccine uptake and explored socio-demographic, economic, and psychological factors that explained vaccine uptake. The survey was administered via Amazon Mechanical Turk (MTurk) to United States residents in January 2017, using the Qualtrics platform. Using principal axis factor analysis, we reduced the 25 items theory-based psychological determinants into the primary constructs they measure if/when internal consistency was sufficient (Cronbach's alpha >0.60). Logistic regression models were used to quantify the association of socio-demographic, economic, and psychological factors with reported vaccine behavior in the 2016-17 flu season. 1007 participants completed the survey, sex distribution was even, 67% had 25-44years of age, and 61% annual household income of $30-99 thousand United States dollars. About 25% had the flu shot offered at their workplace and 20% reported belonging to a group for whom the flu shot is recommended. Vaccine uptake was 31.5%. Eight predictors remained in the final adjusted model (R 2 =0.489), having the vaccine offered at the workplace, belonging to a group for whom the vaccine is recommended, and higher perceived barriers were the strongest predictors of vaccine uptake, increasing (and decreasing in the case of barriers) the odds by >3-fold. Additionally, higher household income, higher perceived susceptibility and higher perceived benefits also independently predicted vaccine uptake. We found evidence that perceived barriers significantly impaired vaccine uptake to the same extent that having the vaccine offered at the workplace or belonging to a group for whom the vaccine is recommended facilitated uptake. Ideally, a better understanding of drivers of

    Autism spectrum disorder (ASD) is characterized by social and communication impairments as well as restricted, repetitive behavior patterns. Despite the fact that ASD is reported worldwide, very little research exists examining ASD characteristics on a multinational scale. Cross-cultural comparisons are especially important for ASD, since cultural differences may impact the perception of symptoms. Identifying behaviors that are similarly reported as problematic across cultures as well as identifying behaviors in which there is cultural variation could aid in the development and refinement of more universally effective measures. The present study sought to examine similarities and differences in caregiver endorsement of symptom severity through scores on the Baby Infant Screen for Children with aUtIsm Traits (BISCUIT). The BISCUIT was utilized to examine ASD core symptomology in 250 toddlers diagnosed with ASD from Greece, Italy, Japan, Poland, and the United States. Significant differences in overall ASD symptom severity and endorsement were found between multinational groups. Implications of the results are discussed. Copyright © 2016 Elsevier Masson SAS.

    Substance use and risk-taking are common during emerging adulthood, a transitional period when peer influences often increase and family influences decrease. Investigating relationships between social network features and substance use can inform community-based prevention programs. This study investigated whether substance use among emerging adults living in disadvantaged urban areas was influenced by peer and family social network messages that variously encouraged and discouraged substance use. Cross-sectional, naturalistic field study. Lower-income neighborhoods in Birmingham, Alabama, USA with 344 participants (110 males, 234 females, ages 15-25 years; mean = 18.86 years), recruited via respondent-driven sampling. During structured interviews conducted in community locations, the Alcohol, Smoking and Substance Involvement Screening Test assessed substance use and related problems. Predictor variables were network characteristics, including presence of substance-using peers, messages from friends and family members about substance use and network sources for health information. Higher substance involvement was associated with friend and family encouragement of use and having close peer network members who used substances (Ps Social networks appear to be important in both promoting and preventing substance use in disadvantaged young adults in the United States. © 2015 Society for the Study of Addiction.

    When the interplay between work and private life does not function correctly (work-home conflict), this constitutes a well-known risk factor for poorer health, increased absenteeism and lower work performance. Information about influencing factors of work-home conflict is therefore indispensable in order to avoid it. In this study, we analyse whether a good working atmosphere that fosters mutual trust, support and a 'sense of unity' (organizational social capital) can reduce an employee's conflict between work and private life. This study investigates the link between organizational social capital and work-home conflict in health professionals. This issue was investigated using a cross-sectional study conducted in 2013. Data from questionnaires completed by physicians and nurses (n=1733) were linked with structural data from 66 neonatal intensive care units in Germany. Using multi-level analyses, we investigated associations between organizational social capital at the ward level and work-home conflict at the level of individual employees, taking into account additional structural and individual characteristics. Employees on wards with greater social capital reported significantly less work-home conflict. Our results support the hypothesis that organizational social capital is an important collective resource. As such, more attention should be given to establishing a good working atmosphere that fosters mutual trust, support and a 'sense of unity', and this should be encouraged in a targeted fashion.

    Introduction: Depression is a major public health issue. One of the concerns in depression research and practice pertains to non-compliance to prescribed medications. The purpose of the study was to predict compliance with medication use for patients with depression using social cognitive theory (SCT). Based on this study it was envisaged that recommendations for interventions to enhance compliance for medication use could be developed for patients with depression. Methods: The study was conducted using cross sectional design (n=148) in southern United States with a convenience sample of clinic-based depression patients with a 37-item valid and reliable questionnaire. Sample size was calculated to be 148 using G*Power (five predictors with a 0.80 power at the 0.05 alpha level and an estimated effect size of 0.10 with an inflation by 10% for missing data). Social cognitive theory constructs of expectations, self-efficacy and self-efficacy in overcoming barriers, self-control, and environment were reified. Data were analyzed using multiple linear regression and multiple logistic regression analyses. Results: Self-control for taking medication for depression (P=0.04), expectations for taking medication for depression (P=0.025), age (PSocial cognitive theory is weakly predictive with low explained variance for taking medication for depression. It needs to be bolstered by newer theories like integrative model or multi-theory model of health behavior change for designing educational interventions aimed at enhancing compliance to medication for depression.

    In this study we examine the economic consequences for firms that cross-delisted from a U.S. stock exchange. Using a sample of foreign firms that cross-delisted from U.S. exchange markets from 2000 to 2012, we investigate the long-term performance, the level of financial constraints, and the likelihood of stock price crashes after the cross-delisting event. We document several new findings as follows: i) cross-delisted firms have less growth opportunities, in the long-run, than their cross-listed peers; ii) after the adoption of Rule 12h-6 of 2007, cross-delisted firms exhibit a significant decline in operating performance; iii) cross-delisted firms underperform their cross-listed peers as they experience negative average abnormal returns, especially in the post-cross-delisting period; iv) cross-delisted firms face higher financial constraints post-delisting than their cross-listed counterparts, and also tend to save more cash out of cash flows; v) the increase in financial constraints post-cross-delisting seems to be primarily driven by informational frictions that constrain access to external financing, which are stronger for firms from countries with weaker investor protection and less developed capital markets; vi) cross-delisted firms experience a significant increase in crash risk associated with earnings management in the post-delisting period relative to a control sample of cross-listed firms, and this effect is more pronounced for delisted firms from countries with weaker investor protection and poor quality of their information environment; vii) cross-delisted firms that engage in earnings management to inflate reported earnings prior to a seasoned equity offering are more likely to a subsequent stock price crash.

    Evidence internationally suggests that staffing constraints and non-supportive work environments result in the rationing of nursing interventions (that is, limiting or omitting interventions for particular patients), which in turn may influence patient outcomes. In the neonatal intensive care unit (NICU), preliminary studies have found that discharge preparation and infant comfort care are among the most frequently rationed nursing interventions. However, it is unknown if the rationing of discharge preparation is related to lower perceptions of parent and infant readiness for NICU discharge, and if reports of increased rationing of infant comfort care are related to lower levels of perceived neonatal pain control. The purpose of this study was to assess these relationships. In late 2014, a cross-sectional survey was mailed to 285 Registered Nurses (RNs) working in one of 7 NICUs in the province of Quebec (Canada). The survey contained validated measures of care rationing, parent and infant readiness for discharge, and pain control, as well as items measuring RNs' characteristics. Multivariate regression was used to examine the association between care rationing, readiness for discharge and pain control, while adjusting for RNs' characteristics and clustering within NICUs. Overall, 125 RNs completed the survey; a 44.0 % response rate. Among the respondents, 28.0 and 40.0 % reported rationing discharge preparation and infant comfort care "often" or "very often", respectively. Additionally, 15.2 % of respondents felt parents and infants were underprepared for NICU discharge, and 54.4 % felt that pain was not well managed on their unit. In multivariate analyses, the rationing of discharge preparation was negatively related to RNs' perceptions of parent and infant readiness for discharge, while reports of rationing of parental support and teaching and infant comfort care were associated with less favourable perceptions of neonatal pain control.

    Full Text Available Background Increasing demand for limited healthcare resources raises questions about appropriate use of inpatient beds. In the first paediatric bed utilisation study at a regional university centre in Ireland, we conducted a cross-sectional study to audit the utilisation of inpatient beds at the Regional Paediatric Unit (RPU in University Hospital Limerick (UHL, Limerick, Ireland and also examined hospital activity data, to make recommendations for optimal use of inpatient resources. Methods We used a questionnaire based on the paediatric appropriateness evaluation protocol (PAEP, modified and validated for use in the United Kingdom, to prospectively gather data regarding reasons for admission and for ongoing care after 2 days, from case records for all inpatients during 11 days in February (winter and 7 days in May–June (summer. We conducted bivariate and multivariate analysis to explore associations between failure to meet PAEP criteria and patient attributes including age, gender, admission outside of office hours, arrival by ambulance, and private health insurance. Inpatient bed occupancy and day ward activity were also scrutinised. Results Mean bed occupancy was 84.1%. In all, 12/355 (3.4%, 95% CI: 1.5%–5.3% of children failed to meet PAEP admission criteria, and 27/189 (14.3%, 95% CI: 9.3%–19.3% who were still inpatients after 2 days failed to meet criteria for ongoing care. 35/355 (9.9%, 95% CI: 6.8%–13.0% of admissions fulfilled only the PAEP criterion for intravenous medications or fluid replacement. A logistic regression model constructed by forward selection identified a significant association between failure to meet PAEP criteria for ongoing care 2 days after admission and admission during office hours (08.00–17.59 (P = .020, and a marginally significant association between this outcome and arrival by ambulance (P = .054. Conclusion At a mean bed occupancy of 84.1%, an Irish RPU can achieve 96.6% appropriate admissions

    To estimate prevalence of type 2 diabetes (diabetes) and impaired fasting glucose (IFG) in the border region between the United States of America and Mexico, by ethnic origin and country of residence; identify risk factors associated with both conditions; and explore the extent to which these factors account for cross-border or ethnic disparities in prevalence. From April 2001 to November 2002, Phase I of the U.S.-Mexico Border Diabetes Prevention and Control Project, a prevalence study of diabetes and its risk factors, was conducted at the U.S.-Mexico border using multistage cluster sampling. A questionnaire was administered on diabetes (self-reported) and lifestyle and a physical examination and blood sample were obtained. A total of 4,027 adults participated in the study: 2,120 Hispanics from the Mexican side of the border and 1,437 Hispanics and 470 non-Hispanics (of whom 385 were classified as "white") from the U.S. side of the border. The age-adjusted prevalence of self-reported and unrecognized diabetes in Hispanics was 15.4% (16.6% on the Mexican side of the border and 14.7% on the U.S. side). The age-adjusted prevalence of IFG was similar on both sides of the border (14.1% on the Mexican side and 13.6% on the U.S. side). Established risk factors for diabetes (e.g., age, obesity, and family history) were relevant and there was an inverse relationship between diabetes and education and socioeconomic level. While diabetes prevalence is high on both sides of the U.S.-Mexico border, one-third of the cases remain undiagnosed, suggesting a need for development and implementation of a public health program for prevention, diagnosis, and control of diabetes in the region.

    There are two types of barriers to the utilisation of maternal health and antenatal care (ANC) services, including the supply-side barriers operating at the health facility level and demand-side, affecting the utilisation ANC services by pregnant women. The purpose of the study was to assess the essential resources required for the provision of ANC services in primary healthcare facilities in Punjab, Pakistan. A cross-sectional facility assessment was conducted in primary healthcare facilities across Punjab. A multi-stage sampling was used to randomly select nine districts from three stratifications and 19 primary healthcare facilities in the public sector (17 Basic Health Units (BHUs) and two Rural Health Centres (RHCs)) from each district. A total of 171 health facilities were included. Data on infrastructure and availability of equipment, essential supplies, medicines, treatment protocols, and infection control items was collected through pre-tested, semi-structured questionnaires. Univariate analysis was carried out to describe the frequency and percentages of facilities across three ratings (good, average, and poor) by type of facility. Overall, 28% of facilities had poor infrastructure and the availability of equipment was poor in 16% of the health facilities. Essential supply items, such as urine strips for albumin, blood sugar testing strips, and haemoglobin reagents, were particularly poorly stocked. However, infrastructure and the availability of equipment and supplies were generally better in RHCs compared to BHUs. Health facilities lacked the resources required to provide quality ANC services, particularly in terms of infrastructure, equipment, supply items, and medicines. The availability of these resources needs to be urgently addressed.

    Since the onset of cross hormone therapy (CHT) in transsexual individuals, there has been concern about possible chronic side effects. Our objective was to assess baseline differences in lipid profile in individuals with gender identity disorder in relation to prior CHT, and changes in the lipid profile and other cardiovascular (CV) risk factors after 24 months of treatment. Retrospective longitudinal study including all individuals assisted for the first time in the Gender Identity Unit of Catalonia from 2006 to 2010. Socio-demographical, anthropometric and laboratory data were collected. We evaluated 247 transsexuals, 150 male to female (MtF: 60.7%) and 97 female to male (FtM; 39.3%). At baseline, FtM transsexuals were younger and had started prior CHT less often than MtF (13.4% vs. 64.7%; pMtF weight and BMI increased significantly, as well as systolic and diastolic blood pressure, though these latter remained within normal range. No significant differences in lipid profile were observed. FtM transsexuals also presented an increase in weight and BMI, without differences in blood pressure. A general worsening in lipid profile was observed in this group, with increased total cholesterol (166.0 ± 35.1 vs. 175.6 ± 38.2mg/dL; p=0.001), triglycerides (70.6 ± 30.7 vs. 102.3 ± 68.5 mg/dL; pMtF transsexuals who were treated with currently prescribed estrogenic compounds, while a slight worsening in lipid profile takes place in the FtM group, though within normal limits.

    Full Text Available Abstract Introduction: Acute kidney injury (AKI is a complication still poorly studied in the setting of obstetric patients, which is associated with increased mortality. Objective: The aim of this study was to investigate the frequency and risk factors of AKI among critically ill obstetric patients. Methods: A cross-sectional study was conducted with all patients admitted to an intensive care unit (ICU due to obstetric complications, in Fortaleza, Brazil, in the period between January 2012 and December 2014. AKI was defined according to AKIN criteria. Results: A total of 389 patients were included, aged between 13 and 45 years. The main causes of ICU admission were pregnancy-related hypertensive syndromes (54.5%, hemorrhage and hemorrhagic shock (12.3%, heart diseases (9.0%, respiratory insufficiency (8.2% and sepsis (5.4%. AKI was found in 92 cases (24%, and this was the most frequent complication. General mortality was 7.5%, and mortality due to AKI was 21% (p = 0.0007. In the multivariate analysis, risk factors for AKI were cesarian delivery (95% CI = 0.23-0.85, p = 0.01 and thrombocythopenia (95% CI = 1.50-4.36, p = 0.001. AKI was an independent risk factor for death (OR = 6.64, 95% CI = 3.11-14.15, p < 0.001. Conclusion: AKI was the main complication among critically ill obstetric patients and it was associated with increased mortality. Most cases were associated with pregnancy-related hypertensive disorders, which are complications that can be easily identified and treated during prenatal care.

    Firearm laws in one state may be associated with increased firearm death rates from homicide and suicide in neighboring states are uncertain. To determine whether counties located closer to states with lenient firearm policies have higher firearm death rates. This cross-sectional study of firearm death rates by county for January 2010 to December 2014 examined data from the US Centers for Disease Control and Prevention for firearm suicide and homicide decedents for 3108 counties in the 48 contiguous states of the United States. Each county was assigned 2 scores, a state policy score (range, 0-12) based on the strength of its state firearm laws, and an interstate policy score (range, -1.33 to 8.31) based on the sum of population-weighted and distance-decayed policy scores for all other states. Counties were divided into those with low, medium, and high home state and interstate policy scores. County-level rates of firearm, nonfirearm, and total homicide and suicide. With multilevel Bayesian spatial Poisson models, we generated incidence rate ratios (IRR) comparing incidence rates between each group of counties and the reference group, counties with high home state and high interstate policy scores. Stronger firearm laws in a state were associated with lower firearm suicide rates and lower overall suicide rates regardless of the strength of the other states' laws. Counties with low state scores had the highest rates of firearm suicide. Rates were similar across levels of interstate policy score (low: IRR, 1.34; 95% credible interval [CI], 1.11-1.65; medium: IRR, 1.36, (95% CI, 1.15-1.65; and high: IRR, 1.43; 95% CI, 1.20-1.73). Counties with low state and low or medium interstate policy scores had the highest rates of firearm homicide. Counties with low home state and interstate scores had higher firearm homicide rates (IRR, 1.38; 95% CI, 1.02-1.88) and overall homicide rates (IRR, 1.32; 95% CI, 1.03-1.67). Counties in states with low firearm policy scores had lower

    Full Text Available Objective  To investigate the prevalence and risk factors of post-traumatic sepsis, and to evaluate the rationality of the 1992, 2001 and 2012 international sepsis definitions in diagnosing post-traumatic sepsis in a trauma intensive care unit (ICU in China. Methods  A one-day cross-sectional survey of trauma patients who met the inclusion criteria was conducted from 8:00 a.m., June 16, 2014 to 8:00 a.m., June 17, 2014 in the trauma ICU of Daping Hospital. The survey data included demographic information, clinical characteristics, pertinent scores (APACHE Ⅱ, SOFA, GCS, ISS and injury mechanism. According to the definition of sepsis as depicted in the 1992, 2001, and 2012 "International Guideline of Sepsis", the patients were divided into A, B and C groups. The infection site, infection pathogens, and key medical treatment were recorded, the infection identified, and the 28day mortality recorded. A positive pathogen culture of respiratory and urinary tracts, blood, cerebrospinal fluid, and wound secretion was adopted as the diagnostic "gold standard" for septic infection. The diagnostic sensitivity and specificity of the three versions of the guidelines were statistically analyzed and the diagnostic feasibility of each definition was assessed. Results  A total of 30 trauma patients were enrolled, twenty-three patients met the 1992 sepsis criteria, 22 met the 2001 criteria, and 20 met the 2012 criteria. The prevalence rates were 76.7%, 73.3%, and 66.7%, respectively, and there was no significant statistical difference. Four patients died within 28 days, which was in line with the diagnostic criteria of the three versions of the sepsis criteria. The 28-day mortality in the three sepsis guidelines groups was 17.4%, 18.2%, and 25.0%, respectively, indicating no statistical difference. By adopting culture-positive pathogens as the "gold standard" of septic infection, the diagnostic sensitivity and specificity of the group A was 77.8% and 25

    History supports the staff and single serpent, the asklepian, as the symbol of healing and medicine, yet its confusion with the caduceus (a winged staff with two snakes wrapped around it) persists. No population-based information on serpent symbol use exists. To determine the prevalence of asklepian and caduceus display among Internet images of medical and health professional schools' emblems, and to compare asklepian and caduceus display between medical and health professional schools, examining the effects of school longevity and geographic location on symbol display. This cross-sectional survey examined Internet websites and Google Images associated with medical and other health professional schools in the United States, Puerto Rico, and Canada from 2013 to 2015. The primary outcome was display of a traditional or variant asklepian or caduceus among current and past emblems in Google Images. Odds ratios (ORs) and 95% confidence intervals for the comparison of medical versus other health professional schools were calculated by logistic regression. Differences among schools' longevity were assessed with Student's t-tests and linear regression. Among images of current and past emblems of 482 schools-159 medical schools and 323 health professional schools-107 (22.2%) emblems displayed only the traditional, and 205 (42.5%) any, asklepian. Adjusting for geographic region and longevity, medical schools were 59% less likely than health professional schools to display the traditional asklepian (OR 0.41, 95% CI 0.24-0.71, P=.001), and were 7.7 times more likely than health professional schools to display the traditional caduceus. Medical schools were 8% less likely than health professional schools to display any asklepian (OR 0.92, 95% CI 0.62-1.38, P=.70), and were 3.3 times more likely than health professional schools to display any caduceus. Schools' preference of the asklepian over the caduceus confirmed historical origins. Less asklepian and more caduceus display by

    Unplanned readmissions to the intensive care unit (ICU) are highly undesirable, increasing variance in care, making resource planning difficult and potentially increasing length of stay and mortality in some settings. Identifying patients who are likely to suffer unplanned ICU readmission could reduce the frequency of this adverse event. A single academic, tertiary care hospital in the UK. A set of 3326 ICU episodes collected between October 2014 and August 2016. All records were of patients who visited an ICU at some point during their stay. We excluded patients who were ≤16 years of age; visited ICUs other than the general and neurosciences ICU; were missing crucial electronic patient record measurements; or had indeterminate ICU discharge outcomes or very early or extremely late discharge times. After exclusion, 2018 outcome-labelled episodes remained. Area under the receiver operating characteristic curve (AUROC) for prediction of unplanned ICU readmission or in-hospital death within 48 hours of first ICU discharge. In 10-fold cross-validation, an ensemble predictor was trained on data from both the target hospital and the Medical Information Mart for Intensive Care (MIMIC-III) database and tested on the target hospital's data. This predictor discriminated between patients with the unplanned ICU readmission or death outcome and those without this outcome, attaining mean AUROC of 0.7095 (SE 0.0260), superior to the purpose-built Stability and Workload Index for Transfer (SWIFT) score (AUROC=0.6082, SE 0.0249; p=0.014, pairwise t-test). Despite the inherent difficulties, we demonstrate that a novel machine learning algorithm based on transfer learning could achieve good discrimination, over and above that of the treating clinicians or the value added by the SWIFT score. Accurate prediction of unplanned readmission could be used to target resources more efficiently. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article

    Kulesza Joel A.

    2016-01-01

    Full Text Available This paper describes a comparison of contemporary and historical light water reactor shielding and pressure vessel dosimetry cross-section libraries for a boiling water reactor calculational benchmark problem. The calculational benchmark problem was developed at Brookhaven National Laboratory by the request of the U. S. Nuclear Regulatory Commission. The benchmark problem was originally evaluated by Brookhaven National Laboratory using the Oak Ridge National Laboratory discrete ordinates code DORT and the BUGLE-93 cross-section library. In this paper, the Westinghouse RAPTOR-M3G three-dimensional discrete ordinates code was used. A variety of cross-section libraries were used with RAPTOR-M3G including the BUGLE93, BUGLE-96, and BUGLE-B7 cross-section libraries developed at Oak Ridge National Laboratory and ALPAN-VII.0 developed at Westinghouse. In comparing the calculated fast reaction rates using the four aforementioned cross-section libraries in the pressure vessel capsule, for six dosimetry reaction rates, a maximum relative difference of 8% was observed. As such, it is concluded that the results calculated by RAPTOR-M3G are consistent with the benchmark and further that the different vintage BUGLE cross-section libraries investigated are largely self-consistent.

    Although caring for residents with dementia in nursing homes is associated with various stressors for care workers, the role of the unit type, and particularly the proportion of residents with dementia, remains unclear. This study aimed to explore associations between unit type and care worker stress, taking into account additional potential stressors. This cross-sectional study was a secondary data analysis in the Swiss Nursing Homes Human Resources Project, which included data from 3,922 care workers from 156 Swiss nursing homes. Care workers' stress was measured with a shortened version of the Health Professions Stress Inventory. Generalized estimating equation models were used to assess care worker stress and its relationships with three unit types (special care units and others with high or low proportions of residents with dementia), work environment factors, and aggressive resident behavior. After including all potential stressors in the models, no significant differences between the three unit types regarding care worker stress were found. However, increased care worker stress levels were significantly related to lower ratings of staffing and resources adequacy, the experience of verbal aggression, and the observation of verbal or physical aggression among residents. Although the unit type plays only a minor role regarding care worker stress, this study confirms that work environment and aggressive behavior of residents are important factors associated with work-related stress. To prevent increases of care worker stress, interventions to improve the work environment and strengthen care workers' ability to cope with aggressive behavior are suggested.

    To determine whether hospitals with a good organisation of care (such as improved nurse staffing and work environments) can affect patient care and nurse workforce stability in European countries. Cross sectional surveys of patients and nurses. Nurses were surveyed in general acute care hospitals (488 in 12 European countries; 617 in the United States); patients were surveyed in 210 European hospitals and 430 US hospitals. 33 659 nurses and 11 318 patients in Europe; 27 509 nurses and more than 120 000 patients in the US. Nurse outcomes (hospital staffing, work environments, burnout, dissatisfaction, intention to leave job in the next year, patient safety, quality of care), patient outcomes (satisfaction overall and with nursing care, willingness to recommend hospitals). The percentage of nurses reporting poor or fair quality of patient care varied substantially by country (from 11% (Ireland) to 47% (Greece)), as did rates for nurses who gave their hospital a poor or failing safety grade (4% (Switzerland) to 18% (Poland)). We found high rates of nurse burnout (10% (Netherlands) to 78% (Greece)), job dissatisfaction (11% (Netherlands) to 56% (Greece)), and intention to leave (14% (US) to 49% (Finland, Greece)). Patients' high ratings of their hospitals also varied considerably (35% (Spain) to 61% (Finland, Ireland)), as did rates of patients willing to recommend their hospital (53% (Greece) to 78% (Switzerland)). Improved work environments and reduced ratios of patients to nurses were associated with increased care quality and patient satisfaction. In European hospitals, after adjusting for hospital and nurse characteristics, nurses with better work environments were half as likely to report poor or fair care quality (adjusted odds ratio 0.56, 95% confidence interval 0.51 to 0.61) and give their hospitals poor or failing grades on patient safety (0.50, 0.44 to 0.56). Each additional patient per nurse increased the odds of nurses reporting poor or fair

    Few studies have examined the associations between health and the cross-border ties that migrants maintain with their family members in communities of origin. We draw on theory related to social ties, ethnic identity, and mental health to examine cross-border ties as potential moderators of the association between migration-related stress and psychological distress among Latino migrants. Using data from the National Latino and Asian American Survey, we find that remittance sending is associated with significantly lower levels of psychological distress for Cuban migrants, and difficulty visiting home is associated with significantly greater psychological distress for Puerto Rican migrants. There were significant associations between migration-related stressors and psychological distress, although these associations fell to non-significance after accounting for multiple testing. We found little evidence that cross-border ties either buffer or exacerbate the association between migration-related stressors and psychological distress. We consider the findings within the current political and historical context of cross-border ties and separation. PMID:27803264

    Parents of very preterm infants are at great risk for experiencing stress and depression. The so called developmental care oriented approach used in Neonatal Intensive Care Units have beneficial effects for parents. However the actual level of developmental care may vary among units and little is known about how the routine adoption of developmental care affects maternal stress and depression. To investigate the extent to which level of quality of developmental care routinely carried out in 25 tertiary Neonatal Intensive Care Units across Italy affects maternal stress and depression. 178 mothers of healthy very preterm infants with gestational age ≤29wk and/or birth weight ≤1500g and without documented neurologic pathologies were recruited consecutively. 180 full-term mothers were recruited as the control group. To distinguish the quality of developmental care level, each unit was assessed using a specifically developed questionnaire. We compared negative emotional states of mothers by splitting the 25 Neonatal Intensive Care Units into units with high-care and low-care based on median splits for two main care factors: (1) The Infant Centered Care index (consisting of measures of parent involvement, including ability to room in, frequency and duration of kangaroo care and nursing interventions aimed at decreasing infant energy expenditure and promoting autonomic stability). (2) The Infant Pain Management index (consisting of measures to decrease painful experiences including pharmacologic and nursing care practices). Maternal stress was assessed by the Parental Stressor Scale: Neonatal Intensive Care Unit questionnaire. Maternal depressive symptomatology was assessed by the Edinburgh Postnatal Depression Scale questionnaire. Preterm mothers from low-care units in the Infant Pain Management reported higher scores in their perception of stress associated with behavior and appearance of the infant than mothers from high-care units (p=0.05).

    The authors examined avoidance personal goals as concurrent (Study 1) and longitudinal (Study 2) predictors of multiple aspects of well-being in the United States and Japan. In both studies, participants adopted more avoidance personal goals in Japan relative to the United States. Both studies also demonstrated that avoidance personal goals were significant negative predictors of the most relevant aspects of well-being in each culture. Specifically, avoidance personal goals were negative predictors of intrapersonal and eudaimonic well-being in the United States and were negative predictors of interpersonal and eudaimonic well-being in Japan. The findings clarify and extend puzzling findings from prior empirical work in this area, and raise provocative possibilities about the nature of avoidance goal pursuit.

    In the continental US, four terrestrial mammalian species are reservoirs for seven antigenic rabies virus variants. Cross species transmission (CST) occurs when a rabies virus variant causes disease in non-reservoir species. This study analyzed national surveillance data for rabies in terrestrial mammals. The CST rate was defined as: number of rabid non-reservoir animals/number of rabid reservoir animals. CST rates were analyzed for trend. Clusters of high CST rate counties were evaluated using space-time scanning statistics. The number of counties reporting a raccoon variant CST rate >1.0 increased from 75 in 1992 to 187 in 2011; counties with skunk variant CST rates >1.0 remained unchanged during the same period. As of 2011, for every rabid raccoon reported within the raccoon variant region, there were 0.73 cases of this variant reported in non-reservoir animals. Skunks were the most common non-reservoir animal reported with the raccoon rabies variant. Domestic animals were the most common non-reservoir animal diagnosed with a skunk rabies virus variant (n = 1,601). Cross species transmission rates increased fastest among domestic animals. Cross species transmission of rabies virus variants into non-reservoir animals increases the risk of human exposures and threatens current advances toward rabies control. Cross species transmission in raccoon rabies enzootic regions increased dramatically during the study period. Pet owners should vaccinate their dogs and cats to ensure against CST, particularly in regions with active foci of rabies circulation. Clusters of high CST activity represent areas for further study to better understand interspecies disease transmission dynamics. Each CST event has the potential to result in a rabies virus adapted for sustained transmission in a new species; therefore further understanding of the dynamics of CST may help in early detection or prevention of the emergence of new terrestrial rabies virus variants.

    2013-06-01

    Following a sociocultural perspective, this study investigates how students who have grown up using the SI (Système International d'Unités) (metric) or US customary (USC) systems of units for everyday use differ in their knowledge of scale and measurement. Student groups were similar in terms of socioeconomic status, curriculum, native language transparency of number word structure, type of school, and makeup by gender and grade level, while varying by native system of measurement. Their performance on several tasks was compared using binary logistic regression, ordinal logistic regression, and analysis of variance, with gender and grade level as covariates. Participants included 17 USC-native and 89 SI-native students in a school in Mexico, and 31 USC-native students in a school in the Midwestern USA. SI-native students performed at a significantly higher level estimating the length of a metre and a conceptual task (coordinating relative size and absolute size). No statistically significant differences were found on tasks involving factual knowledge about objects or units, scale construction, or estimation of other units. USC-native students in the US school performed at a higher level on smallest known object. These findings suggest that the more transparent SI system better supports conceptual thinking about scale and measurement than the idiosyncratic USC system. Greater emphasis on the SI system and more complete adoption of the SI system for everyday life may improve understanding among US students. Advancing sociocultural theory, systems of units were found to mediate learner's understanding of scale and measurement, much as number words mediate counting and problem solving.

    Physiotherapy is integral to patient management in the Intensive Care Unit. The precise role that physiotherapists play in the critical care differs significantly worldwide. The aim of the study was to describe the profile of patients and the current patterns of physiotherapy services delivered for patients admitted in the five public hospital intensive care units in Zimbabwe. A prospective record review was performed and records of all consecutive patients admitted into the five units during a two months period were included in the analysis. The data was collected using a checklist and the following were recorded for each patient: 1) demographic information, 2) admission diagnoses, 3) surgery classification, 4) method and time of mechanical ventilation 5) physiotherapy techniques and frequency and 6) the length of stay. A total of 137 patients were admitted to five units during the study. The mean age of patients in the study was 36.0 years (SD = 16.6). A mortality rate of 17.5 % was observed with most of the patients being below the age of 45 years. The majority of the patients, 61(45 %) had undergone emergency surgery and were in the ICU for postoperative treatment, whilst only 19(14 %) were in the units for clinical treatment (non-surgical). On admission, 72(52.6 %) of the patients were on mechanical ventilation. The mean duration on mechanical ventilation for patients was 4.0 days (SD =2.7) and a length of stay in the unit of 4.5 days (SD = 3.0). Of the patients who were admitted into the ICU 120 (87.6 %) had at least one session of physiotherapy treatment during their stay. The mean number of days physiotherapy treatment was received was 3.71 (SD = 3.14) days. The most commonly used physiotherapy techniques were active assisted limb movements (66.4 %), deep breathing exercises (65.0 %) and forced expiratory techniques (65.0 %). A young population admitted in the ICU for post-surgical treatment was observed across all hospital ICUs. The techniques which were

    To identify similarities and differences in the behavioral profile of children with Williams syndrome from Spain and the United States, we asked parents of 6 – 14-year-olds from Spain (n=53) and the United States (n=145) to complete the Child Behavior Checklist 6–18. The distribution of raw scores was significantly higher for the Spanish sample than the American sample for half of both the empirically-based and DSM-oriented scales. In contrast, analyses based on country-specific T-scores indicated that the distribution for the Spanish sample was significantly higher than for the American sample only on the Social Problems scale. No gender differences were found. Genetic and cultural influences on children’s behavior and cultural influences on parental ratings of behavior are discussed. PMID:28257245

    This study examined the relationships among social media use for information, self-status seeking and socializing, body image, self-esteem, and psychological well-being, and some cultural effects moderating these relationships. Americans (n = 502) and Koreans (n = 518) completed an online survey. The main findings showed that (a) social media use for information about body image is negatively related to body satisfaction in the United States and Korea, while social media use for self-status seeking regarding body image is positively related to body satisfaction only in Korea; and (b) body satisfaction has direct and indirect positive effects on psychological well-being manifested in similar ways in the United States and Korea. Implications and future research directions are discussed.

    The purpose of this study was to assess the effectiveness of silver-embedded surfaces (BactiBlock®) to prevent surface colonization by multi-resistant bacteria (MRB) and to reduce the incidence of MRB colonization and infection in patients admitted to an intensive care unit (ICU). A 6-month prospective observational study in a 24-bed mixed ICU divided into two identical subunits (12 beds each) was designed. Seven solid mobile screens were placed in one of the subunits while in the other cloth screens remained. Solid screens were constructed with high-density polyethylene embedded in Bactiblock®. To evaluate the effectiveness of screens coated with Bactiblock®, number of MRB isolates on screens were compared for 6 months. Likewise, numbers of new patients and ICU-stays with MRB colonization in the two subunits were compared. One hundred forty screen samples were collected in 10-point prevalent days. MRB were detected on 28 (20.0%) samples. Over the 70 samples taken on cloth folding screens, MRB were detected in 25 (35.7%), while only 3 (4.3%) of the 70 samples taken on Bactiblock® screens were positive for MRB (p unit with Bactiblock® screens presented fewer number of ICU stays with MRB colonization (27.8% vs 47.1%; p units, proving to be an useful tool in the control of MRB.

    Inter-professional collaboration between physicians and nurses, within and between cultures, can help contain cost and insure better patient outcomes. Attitude toward such collaboration is a function of the roles prescribed in the culture that guide professional behavior. The purpose of the study was to test three research hypotheses concerning attitudes toward physician-nurse collaboration across genders, disciplines, and cultures. The Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration was administered to 639 physicians and nurses in the United States (n = 267) and Mexico (n = 372). Attitude scores were compared by gender (men, women), discipline (physicians, nurses), and culture (United States, Mexico) by using a three-way factorial analysis of variance design. Findings confirmed the first research hypothesis by demonstrating that both physicians and nurses in the United States would express more positive attitudes toward physician-nurse collaboration than their counterparts in Mexico. The second research hypothesis, positing that nurses as compared to physicians in both countries would express more positive attitudes toward physician-nurse collaboration, was also supported. The third research hypothesis that female physicians would express more positive attitudes toward physician-nurse collaboration than their male counterparts was not confirmed. Collaborative education for medical and nursing students, particularly in cultures with a hierarchical model of inter-professional relationship, is needed to promote positive attitudes toward complementary roles of physicians and nurses. Faculty preparation for collaboration is necessary in such cultures before implementing collaborative education.

    Adherence to a prescribed therapeutic regimen is a critical factor for achieving medication effectiveness and therefore treatment success. In the case of companion animal ectoparasite control, suboptimal owner adherence to medication recommendations is thought to be a common cause of treatment failure, and previous reports have found pet owners applying an average of 4.0-4.6 monthly flea and tick treatments per year to their dogs. This study investigated: US veterinary hospital self-reported flea and tick prevention recommendations; dog owner recollection of these recommendations; dog owner opinion on flea/tick recommendations and estimated owner flea and tick medication adherence based on veterinary hospital purchase records. Veterinarians at 24 veterinary hospitals in 4 United States regions provided their flea and tick prevention recommendations. Five hundred fifty-nine dog owners, clients of the 24 hospitals, completed a survey evaluating their recollection of the hospitals' recommendations and their opinions regarding required treatment frequency. Almost all veterinary hospitals in this study recommended 12 months of flea and tick prevention but only 62% of participating dog owners recalled this recommendation. The average owner response was that their dogs require 10.5 months of flea and tick prevention annually. Owner opinions were significantly different among U.S. regions with pet owners in the northeast U.S. believing that they needed significantly less canine flea and tick protection than pet owners in other parts of the United States. The estimated actual flea and tick prevention coverage was 6.1 months based on owner medication purchases over a 12-month period. In the United States, dog owner opinions and actions show that their flea and tick treatment adherence falls short of veterinarians' recommendations.

    Violent-related (assault) injuries are a leading cause of death and disability in the United States. Many violent injury victims seek treatment in the emergency department (ED). Our objectives were to (1) estimate rates of violent-related injuries evaluated in United States EDs, (2) estimate linear trends in ED visits for violent-related injuries from 2000 to 2010, and (3) to determine the associated health care and work-loss costs. We examined adults 18 years and older from a nationally representative survey (the National Hospital Ambulatory Medical Care Survey) of ED visits, from 2000 to 2010. Violent injury was defined using International Classification of Diseases-9th Rev.-Clinical Modification, diagnosis and mechanism of injury codes. We calculated rates of ED visits for violent injuries. Medical and work-loss costs accrued by these injuries were calculated for 2005, inflation-adjusted to 2011 dollars using the WISQARS Cost of Injury Reports. An annual average of 1.4 million adults were treated for violent injuries in EDs from 2000 to 2010, comprising 1.6% (95% confidence interval, 1.5%-1.6%) of all US adult ED visits. Young adults (18-25 years), men, nonwhites, uninsured or publically insured patients, and those residing in high poverty urban areas were at increased risk for ED visits for violent injury. The 1-year, inflation-adjusted medical and work-loss cost of violent-inflicted injuries in adults in the United States was US $49.5 billion. Violent injuries account for over one million ED visits annually among adults, with no change in rates over the past decade. Young black men are at especially increased risk for ED visits for violent injuries. Overall, violent-related injuries resulted in substantial financial and societal costs.

    Although Asian preschoolers acquire executive functions (EFs) earlier than their Western counterparts, little is known about whether this advantage persists into later childhood and adulthood. To address this gap, in the current study we gave four computerized EF tasks (providing measures of inhibition, working memory, cognitive flexibility, and planning) to a large sample ( n = 1,427) of 9- to 16-year-olds and their parents. All participants lived in either the United Kingdom or Hong Kong. Our findings highlight the importance of combining developmental and cultural perspectives and show both similarities and contrasts across sites. Specifically, adults' EF performance did not differ between the two sites; age-related changes in executive function for both the children and the parents appeared to be culturally invariant, as did a modest intergenerational correlation. In contrast, school-age children and young adolescents in Hong Kong outperformed their United Kingdom counterparts on all four EF tasks, a difference consistent with previous findings from preschool children.

    To examine predictors of health care service utilization in Mexico or any other country in Latin America among the U.S. Hispanic population. This study used data from the 2007 Pew Hispanic Healthcare Survey, a nationally representative survey of 4013 Hispanic adults. Using the Behavioral Model of Health Service Use (BMHSU) model, we examined three levels of predictive factors: (1) predisposing characteristics (e.g., language proficiency), (2) enabling resources (e.g., health insurance status), and (3) need (e.g., self-perceived health status). Multivariate logistic regression analyses were conducted to predict odds of seeking health care services in Mexico or any other country in Latin America. As hypothesized, lack of continuous health insurance coverage, perceived lack of quality health care, and low English proficiency increased the likelihood of seeking health care in Mexico or any other Latin American country among US Hispanic adults. Self-reported health status and usual source of care, however, were not significant predictors. Hispanic immigrants face critical access gaps to health care in the United States. Implications for closing the access gap for this population are discussed within the context of health care system reform and immigration reform in the United States.

    Using samples from three diverse populations, we test evolutionary hypotheses regarding how people reason about the inheritance of various traits. First, we provide a framework for differentiat-ing the outputs of mechanisms that evolved for reasoning about variation within and between (a) biological taxa and (b) culturally evolved ethnic categories from (c) a broader set of beliefs and categories that are the outputs of structured learning mechanisms. Second, we describe the results of a modified "switched-at-birth" vignette study that we administered among children and adults in Puno (Peru), Yasawa (Fiji), and adults in the United States. This protocol permits us to study perceptions of prenatal and social transmission pathways for various traits and to differentiate the latter into vertical (i.e., parental) versus horizontal (i.e., peer) cultural influence. These lines of evidence suggest that people use all three mechanisms to reason about the distribution of traits in the population. Participants at all three sites develop expectations that morphological traits are under prenatal influence, and that belief traits are more culturally influenced. On the other hand, each population holds culturally specific beliefs about the degree of social influence on non-morphological traits and about the degree of vertical transmission-with only participants in the United States expecting parents to have much social influence over their children. We reinterpret people's differentiation of trait transmission pathways in light of humans' evolutionary history as a cultural species. Copyright © 2015 Cognitive Science Society, Inc.

    A bundled approach to intensive care unit (ICU) care known as "Awakening and Breathing Coordination, Delirium monitoring/management, and Early exercise/mobility" (ABCDE) has been proposed, with evidence supporting individual interventions as well as the bundle as a whole. Few data exist on the bundle's implementation and efficacy in community practice. To evaluate self-reported rates of implementation of ABCDE components and their association with outcomes in a state-wide quality improvement collaborative. A written survey was administered to representatives attending the 2012 annual meeting of the Michigan Health and Hospital Association's Keystone ICU collaborative. Respondents reported on their practices regarding spontaneous awakening trials, delirium assessments, and early mobility. There were 212 respondents, a 76% response rate. Wide variation in focus was noted across the assessed components of ABCDE. Only 12% reported having implemented routine spontaneous awakening trials and delirium assessments as well as early mobility, 36% reported not having early mobility as an active goal in their units (nonmovers), and 52% reported attempts at early mobility without both routine sedation interruption and delirium screening implementation. In adjusted models, those who implemented exercise with sedation interruption and delirium screening were 3.5 (95% confidence interval, 1.4-8.6) times more likely to achieve higher levels of exercise in ventilated patients than those who implemented exercise without both sedation interruption and delirium screening. There is incomplete penetrance of aspects of ABCDE across ICUs in this highly motivated statewide quality improvement collaborative. Yet, implementation of exercise in the context of both sedation interruption and delirium screening was associated with improved self-reported mobility outcomes. Effective knowledge translation and implementation strategies may offer substantial benefits to ICU patients.

    Full Text Available Previous studies have described racial and socioeconomic disparities in the treatment of infertility. Patient factors such as attitudes and awareness may be contributing factors. Since primary care is often the setting that serves as an entry into other areas of medicine, we sought to evaluate men's attitudes and awareness of male infertility in the primary care setting. To do this, we performed a cross-sectional survey of men's attitudes toward men's health issues in 210 men from two primary care clinic waiting rooms in Atlanta, Georgia. The survey was self-administered with closed-ended question items and was approximately 20 min in length. Of the 310 men approached, 210 agreed to participate and returned completed surveys. Overall, 52% of men said they were "very" or "somewhat" familiar with infertility and 25% were familiar with treatments for infertility. Some men had heard of surgery (21% and medication (35% as treatments for male infertility. Awareness and familiarity with the condition was greater in high socioeconomic status men (i.e. college graduates or those with income >$100 k per year but did not differ by race on multivariate analysis. Attitudes toward infertility varied by race with non-Caucasian men being more likely to indicate that infertility is a serious condition, to be concerned about infertility, and to believe it decreases a man's quality-of-life. Therefore, a lack of awareness, but not negative attitudes, may contribute to previously-described disparities in the treatment of infertility.

    This multicentre cross-sectional study aims to estimate the prevalence of five neglected tropical diseases (Chagas disease, filariasis, schistosomiasis, strongyloidiasis and toxocariasis) among immigrants accessing health care facilities in five Italian cities (Bologna, Brescia, Florence, Rome, Verona). Individuals underwent a different set of serological tests, according to country of origin and presence of eosinophilia. Seropositive patients were treated and further followed up. A total of 930 adult immigrants were enrolled: 477 men (51.3%), 445 women (47.9%), eight transgender (0.8%); median age was 37.81 years (range 18-80 years). Most of them had come from the African continent (405/930, 43.5%), the rest from East Europe, South America and Asia, and 9.6% (89/930) were diagnosed with at least one of the infections under study. Seroprevalence of each specific infection varied from 3.9% (7/180) for Chagas disease to 9.7% (11/113) for toxocariasis. Seropositive people were more likely to be 35-40 years old and male, and to come from South East Asia, sub-Saharan Africa or South America. The results of our study confirm that neglected tropical diseases represent a substantial health problem among immigrants and highlight the need to address this emerging public health issue.

    Since the introduction of orthodontic therapists (OTs), there has been little research on the scope of practice and the level of supervision they receive. This study investigates how OTs are being utilised and supervised, and how this compares with current recommendations. A postal cross-sectional survey was mailed to all UK General Dental Council (GDC) registered specialist orthodontists. A 59.7% response rate (747) was achieved. 52% of the respondents reported they worked with/employed an OT. The majority of orthodontists worked with an OT in primary care (67%) seeing predominantly NHS (56%) patients and performed a wide range of duties. Orthodontists reported a perceived increase in clinical output (74%) and time available for treatment planning (61%). The majority (85%) of orthodontists indicated they provide a written prescription for the OT. Forty-two per cent reported the prescription did not contain the required information as stipulated by the GDC. OTs are valued members of the orthodontic team, improving productivity and allowing orthodontists more time for treatment planning. The majority of orthodontists appeared to be working to the BOS and GDC recommendations, with greater awareness needed regarding the provision of a written treatment prescription.

    Full Text Available Abstract Objective This cross-sectional study sought to determine the prevalence of cardiometabolic risk factor clusters (CMRFCs and their effect on BP control among hypertensive patients from 28 US physician practices. Methods Each participating practice identified a random sample of 150-300 adults aged ≥ 18 years diagnosed with hypertension. The primary outcome variable was BP control (BP Results Overall, 6,527 hypertensive patients were identified for study inclusion. More than half (54.3% were female, and mean age was 64.7 years. Almost half (48.7% were obese (BMI ≥ 30 kg/m2. About 1 in every 4 patients (25.3% had diabetes, and 60.7% had dyslipidemia. Mean blood pressure was 132.5/77.9 mmHg, and 55.0% of all patients had controlled BP; 62.4% of non-diabetic patients, and 33.3% of diabetic hypertensive patients, had BP controlled to recommended levels. Most (81.7% hypertensive patients had ≥ 1 cardiometabolic risk factor, and 12.2% had all 3 risk factors. As compared to hypertensive patients without additional risk factors, adjusted odds ratios for BP control were significantly lower for all combinations of CMRFCs (ORs 0.15-0.83, all p Conclusions Across 28 US practices, only 18% of hypertensive patients did not have any additional cardiometabolic risk factors. The high prevalence of CMRFCs presents a challenge to effective hypertension management.

    Low individual-level socioeconomic status (SES) is associated with higher prevalence of cigarette smoking. Recent work has examined whether neighborhood-level SES may affect smoking behavior independently from individual-level measures. However, few comparisons of neighborhood-level effects on smoking by race and gender are available. Cross-sectional data from adults age 40-79 enrolled in the Southern Community Cohort Study from 2002-2009 (19, 561 black males; 27, 412 black females; 6, 231 white males; 11, 756 white females) were used in Robust Poisson regression models to estimate prevalence ratios (PRs) and 95% confidence intervals (CI) for current smoking in relation to individual-level SES characteristics obtained via interview and neighborhood-level SES characteristics represented by demographic measures from US Census block groups matched to participant home addresses. Several neighborhood-level SES characteristics were modestly associated with increased smoking after adjustment for individual-level factors including lower percentage of adults with a college education and lower percentage of owner-occupied households among blacks but not whites; lower percentage of households with interest, dividends, or net rental income among white males; and lower percentage of employed adults among black females. Lower neighborhood-level SES is associated with increased smoking suggesting that cessation programs may benefit from targeting higher-risk neighborhoods as well as individuals.

    Objective To evaluate cross-sectional patient distribution and standardised 30-day mortality in the intensive care units (ICU) of an inclusive hub and spoke trauma system. Setting ICUs of the Integrated System for Trauma Patient Care (SIAT) of Emilia-Romagna, an Italian region with a population of approximately 4.5 million. Participants 5300 patients with an Injury Severity Score (ISS) >15 were admitted to the regional ICUs and recorded in the Regional Severe Trauma Registry between 2007 and 2012. Patients were classified by the Abbreviated Injury Score as follows: (1) traumatic brain injury (2) multiple injuriesand (3) extracranial lesions. The SIATs were divided into those with at least one neurosurgical level II trauma centre (TC) and those with a neurosurgical unit in the level I TC only. Results A higher proportion of patients (out of all SIAT patients) were admitted to the level I TC at the head of the SIAT with no additional neurosurgical facilities (1083/1472, 73.6%) compared with the level I TCs heading SIATs with neurosurgical level II TCs (1905/3815; 49.9%). A similar percentage of patients were admitted to level I TCs (1905/3815; 49.9%) and neurosurgical level II TCs (1702/3815, 44.6%) in the SIATs with neurosurgical level II TCs. Observed versus expected mortality (OE) was not statistically different among the three types of centre with a neurosurgical unit; however, the best mean OE values were observed in the level I TC in the SIAT with no neurosurgical unit. Conclusion The Hub and Spoke concept was fully applied in the SIAT in which neurosurgical facilities were available in the level I TC only. The performance of this system suggests that competition among level I and level II TCs in the same Trauma System reduces performance in both. The density of neurosurgical centres must be considered by public health system governors before implementing trauma systems. PMID:28965094

  9. Development of a Wien filter electron polarimeter

    Energy Technology Data Exchange (ETDEWEB)

    Dowlatshahi, N.M

    1999-04-01

    According to current ideas only left-handed fermion currents participate in the weak interaction. However there exist left-right symmetric variants of electroweak theory with right-handed currents which couple with equal intrinsic strength, whose contribution is suppressed by the presumed relatively greater mass of the mediating vector bosons. One route to detecting the presence of right-handed currents is to measure the velocity-dependence of the polarization of electrons from mixed Fermi/Gamow-Teller {beta}-transitions. This thesis describes the theory, construction and operation of a Wien filter which is a system of crossed uniform electric and magnetic fields which transmits electrons of velocity v = E/B, and is therefore an ideal instrument for precise velocity measurements. The filter is based on a 2.5 meter long uniform field electromagnet purpose built at Oak Ridge some thirty years ago to study the electric and magnetic dipole moments of the neutron. The thesis comes in two parts: the first part presents the exact theory of relativistic electron motion in an ideal crossed field system, together with numerical programs for examining the effects of imperfections of which electric field non-uniformity and remnant magnetism turn out to be the most important. This is followed by the constructional details of the velocity filter including electric and magnetic field measurements, vacuum performance and the method for detecting and processing electron signals. This part concludes with an account of the successful testing of the filter using 62.5 keV and 84.5 keV internal conversion electrons from an electron-capture source of 453 day {sup 109}Cd. The second part of the thesis deals with the dynamics of electron spin motion in crossed fields; in particular with spin rotation from longitudinal to transverse orientation which is necessary for applying the method of Mott scattering from heavy nuclei for electron polarization determination. This part also describes

    The strong comorbidity between substance use disorders (SUDs) and mood and anxiety disorders has been well documented. In view of lack of research findings addressing the co-occurrence of SUDs and mood and anxiety disorders, this study examined the pattern of comorbidity of alcohol use disorders (AUDs) and nicotine dependence (ND) between 2 culturally diverse countries, the United States and South Korea. Using the nationally representative samples of the U.S. and Korean general populations, we directly compared rates and comorbidity patterns of AUDs, ND, and mood and anxiety disorders between the 2 countries. We further examined the rates and the comorbidity pattern among individuals with AUDs who sought treatment in the last 12 months. Twelve-month prevalence rates were derived to estimate country differentials, and odds ratios (ORs) and 95% confidence intervals were estimated to measure the strength of comorbid associations while adjusting for all sociodemographic characteristics in multivariate logistic models specific to each country. The 12-month prevalence rates of AUDs, ND, and any mood disorder and any anxiety disorder were 9.7, 14.4, 9.5, and 11.9% among Americans, whereas the corresponding rates were 7.1, 6.6, 2.0, and 5.2% among Koreans. These rates were significantly greater (except for any AUD) among Americans than among their Korean counterparts. With respect to comorbidity, both countries showed comparable patterns that the prevalence rates of mood and anxiety disorders were consistently the highest among persons with alcohol dependence (AD). Also, a disparate pattern was observed in Korea that the prevalence rates of mood and anxiety disorders were generally lower among individuals with ND than among those with alcohol abuse and AD. Furthermore, despite significantly greater prevalence of AD in Korea (5.1%) than in the United States (4.4%), alcohol-dependent Americans were 4 times (OR = 3.93) more likely to seek treatment compared to their Korean

    Communication errors are considered one of the major causes of sentinel events. Our aim was to assess the process of patient handoff among junior surgical residents and to determine ways in which to improve the handoff process. We conducted nationwide surveys that included all accredited general surgery residency programs in the United States and Canada. Of the 244 American and 17 Canadian accredited surgical residency programs contacted, 65 (27%) and 12 (71%), respectively, participated in the survey. Of the American and Canadian respondents, 66% and 69%, respectively, were from postgraduate year (PGY) 1, and 32% and 29%, respectively, were from PGY 2; 85 (77%) and 50 (96%), respectively, had not received any training about patient handoff before their surgical residency, and 27% and 64%, respectively, reported that the existing handoff system at their institutions did not adequately protect patient safety. Moreover, 29% of American respondents and 37% of Canadian respondents thought that the existing handoffs did not support continuity of patient care. Of the American residents, 67% and 6% reported receiving an incomplete handoff that resulted in minor and major patient harm, respectively. These results mirrored those from Canadian residents (63% minor and 7% major harm). The most frequent factor reported to improve the patient handoff process was standardization of the verbal handoff. Our survey results indicate that the current patient handoff system contributes to patient harm. More efforts are needed to establish standardized forms of verbal and written handoff to ensure patient safety and continuity of care.

    Objectives Despite growing recognition of the importance of speaking up to protect patient safety in critical care, little research has been performed in this area in an intensive care unit (ICU) context. This study explored the communication openness perceptions of Chinese doctors and nurses and identified their perceptions of issues in ICU communication, their reasons for speaking up and the possible factors and strategies involved in promoting the practice of speaking up. Design A mixed-methods design with quantitative and sequential qualitative components was used. Setting and participants Eighty ICU staff members from a large public hospital in Hong Kong completed a questionnaire regarding their perceptions of communication openness. Ten clinicians whose survey responses indicated support for open communication were then interviewed about their speak-up practices. Results The participating ICU staff members had similar perceptions of their openness to communication. However, the doctors responded more positively than the nurses to many aspects of communication openness. The two groups also had different perceptions of speaking up. The interviewed ICU staff members who indicated a high level of communication openness reported that their primary reasons for speaking up were to seek and clarify information, which was achieved by asking questions. Other factors perceived to influence the motivation to speak up included seniority, relationships and familiarity with patient cases. Conclusions Creating an atmosphere of safety and equality in which team members feel confident in expressing their personal views without fear of reprisal or embarrassment is necessary to encourage ICU staff members, regardless of their position, to speak up. Because harmony and saving face is valued in Chinese culture, training nurses and doctors to speak up by focusing on human factors and values rather than simply addressing conflict management is desirable in this context.

    In intensive care units (ICUs), inanimate surfaces and equipment may be contaminated by nosocomial pathogens, including multi-drug-resistant micro-organisms. To assess the degree of environmental contamination close to and distant from patients, and contamination of healthcare workers' (HCWs) hands with nosocomial pathogens under real-life conditions and to investigate potential transmission events. Over the course of three weeks, agar contact samples were taken close to and distant from patient areas and from HCWs' hands in eight ICUs of a tertiary care hospital in Innsbruck, Austria. Each ICU was visited once without announcement. Species identification and antimicrobial susceptibility testing were performed according to standard methods, and corresponding strains from patient, environment and hand samples were genotyped using pulsed-field gel electrophoresis. Among 523 samples, HCWs' hands were most frequently contaminated with potentially pathogenic bacteria (15.2%), followed by areas close to patients (10.9%) and areas distant from patients (9.1%). Gram-positive bacteria were identified most often (67.8%), with Enterococcus spp. being the most prevalent species (70% vancomycin sensitive and 30% vancomycin resistant) followed by Staphylococcus aureus, of which 64% were classified as meticillin-resistant Staphylococcus aureus. Molecular typing documented identical strains among patient, environment and hand isolates. This study found widespread contamination of the ICU environment with clinically relevant pathogens, including multi-drug-resistant micro-organisms, despite cleaning and disinfection. The bioburden might not be restricted to areas close to patients. The role of extended environmental disinfection of areas distant from patients in order to improve infection prevention needs further discussion. Copyright © 2017 The Healthcare Infection Society.

    Full Text Available Accurate information about the prevalence and types of tobacco use is essential to deliver effective public health policy. We aimed to study the prevalence and modes of tobacco consumption in the United Arab Emirates (UAE, particularly focusing on the use of Midwakh (Arabic traditional pipe.We studied 170,430 UAE nationals aged ≥ 18 years (44% males and 56% females in the Weqaya population-based screening program in Abu Dhabi residents during the period April 2008-June 2010. Self-reported smoking status, type, quantity and duration of tobacco smoked were recorded. Descriptive statistics were used to describe the study findings; prevalence rates used the screened sample as the denominator.The prevalence of smoking overall was 24.3% in males and 0.8% in females and highest in males aged 20-39. Mean age (SD of smokers was 32.8 (11.1 years, 32.7 (11.1 in males and 35.7 (12.1 in females. Cigarette smoking was the commonest form of tobacco use (77.4% of smokers, followed by Midwakh (15.0%, shisha (waterpipe (6.8%, and cigar (0.66%. The mean durations of smoking for cigarettes, Midwakh, shisha and cigars were 11.4, 9.3, 7.6 and 11.0 years, respectively.Smoking is most common among younger UAE national men. The use of Midwakh and the relatively young age of onset of Midwakh smokers is of particular concern as is the possibility of the habit spreading to other countries. Comprehensive tobacco control laws targeting the young and the use of Midwakh are needed.

    Full Text Available Abstract Background Foot symptoms in rheumatoid arthritis (RA derive from a combination of inflammation, altered foot mechanics, deformity and secondary skin lesions. Guidelines recommend regular review of patients’ feet, but the extent to which the general population of RA patients report foot symptoms and access foot care has not been established. The aims of this study were to determine the prevalence, impact and care of foot problems in all patients with RA in one geographical area and identify factors associated with accessing foot care.

    The link between depression and aggressive behavior in adults has been found in many studies. In adolescents, this relationship is still controversial. Several studies point out that irritability is a key symptom in adolescent depressed. Few studies have analyzed precisely the kind of aggressive behavior. This study sets out to assess the relationship between aggressive behavior and depressive affects in adolescents. We also pay attention in this population to hopelessness feelings, anxiety, global functioning and the type of aggressive behavior. This is a descriptive and observational cross-sectional study. Data was collected from 49 successive adolescents admitted for a 24-hour evaluation in the emergency department of the Sainte-Anne psychiatric hospital. The inclusion period was from February to April 2012, with age limits between 15 and 18. For each patient, the clinician completed with the parents or other caregivers the Modified Overt Aggressive Scale (MOAS) searching for existence of aggressive behavior in the week prior to the consultation. The population was divided into two groups: P- group when the MOAS score was Adolescent Depression Rating Scale for clinicians (ADRSc) were also completed. Each patient completed the self-report Buss-Perry Aggression Questionnaire (QA), the Beck Hopelessness scale and the Adolescent Depression Rating Scale for patients (ADRSp). Forty-nine adolescents with a median age of 16 years and 4 months participated. The first reason for consultation was depressive symptoms, followed by disruptive behavior. The analysis was conducted on 39 questionnaires. The demographic profile of the two groups was similar. We did not find any significant difference between the groups P+ and P- on ADRSc scores and secondary criteria. However, we found higher scores in the QA in the more depressed patient, especially a higher hostility score in this sample. In the subgroup analysis: as expected self-aggressive behavior was associated with a

    Background In 2015 meningococcal group W was declared endemic in the UK, with the meningococcal ACWY vaccination (MenACWY) subsequently introduced amongst adolescents and first-year university students. This study aimed to determine MenACWY uptake amongst students and to evaluate how this was influenced by demographics and via the Health Belief Model (HBM). Methods This was a cross-sectional study conducted at a British university amongst first-year undergraduate students aged 18–25 years. Data collection was via an electronic questionnaire encompassing demographics, the HBM and vaccination status. Univariable analysis of the associations between demographics, health beliefs and vaccination was performed, followed by multiple logistic regression. Results 401 participants were included in analysis. Vaccine uptake was 68.1%. Variables independently associated with vaccination upon multiple regression were age, gap-year, perceived effectiveness of the vaccine and knowledge about risk of meningitis. Compared to 18 year-olds, the odds of vaccination were reduced for 19 year-olds (aOR = 0.087, 95% CI = 0.010–0.729), 20 year-olds (aOR = 0.019, 95% CI = 0.002–0.161) and 21–25 year-olds (aOR = 0.003, 95% CI = vaccine effectiveness (aOR = 3.555, 95% CI = 1.787–7.073) and knowledge about meningitis risk (aOR = 2.481, 95% CI = 1.165–5.287) were independently associated with increased uptake. Conclusions MenACWY uptake amongst students in this study and in other sources is above the national coverage for all adolescents (35.3%), indicating that this vaccination programme may be increasing health inequalities. Older students are less likely to become vaccinated due to differing vaccination policy in this age-group. In future, strategies that focus on specific student cohorts and that highlight vaccine effectiveness and the risk of meningitis should be considered. National evaluation of this vaccination programme is recommended to clarify its impact on health

    Full Text Available Care advances in the United States (US have led to improved survival of children with neurological impairment (NI. Children with NI may account for an increasing proportion of hospital resources. However, this assumption has not been tested at a national level.We conducted a study of 25,747,016 US hospitalizations of children recorded in the Kids' Inpatient Database (years 1997, 2000, 2003, and 2006. Children with NI were identified with International Classification of Diseases, 9th Revision, Clinical Modification diagnoses resulting in functional and/or intellectual impairment. We assessed trends in inpatient resource utilization for children with NI with a Mantel-Haenszel chi-square test using all 4 y of data combined. Across the 4 y combined, children with NI accounted for 5.2% (1,338,590 of all hospitalizations. Epilepsy (52.2% [n = 538,978] and cerebral palsy (15.9% [n = 164,665] were the most prevalent NI diagnoses. The proportion of hospitalizations attributable to children with NI did not change significantly (p = 0.32 over time. In 2006, children with NI accounted for 5.3% (n = 345,621 of all hospitalizations, 13.9% (n = 3.4 million of bed days, and 21.6% (US$17.7 billion of all hospital charges within all hospitals. Over time, the proportion of hospitalizations attributable to children with NI decreased within non-children's hospitals (3.0% [n = 146,324] in 1997 to 2.5% [n = 113,097] in 2006, p<.001 and increased within children's hospitals (11.7% [n = 179,324] in 1997 to 13.5% [n = 209,708] in 2006, p<0.001. In 2006, children with NI accounted for 24.7% (2.1 million of bed days and 29.0% (US$12.0 billion of hospital charges within children's hospitals.Children with NI account for a substantial proportion of inpatient resources utilized in the US. Their impact is growing within children's hospitals. We must ensure that the current health care system is staffed, educated, and equipped to serve this growing segment of vulnerable children.

    To evaluate cross-sectional patient distribution and standardised 30-day mortality in the intensive care units (ICU) of an inclusive hub and spoke trauma system. ICUs of the Integrated System for Trauma Patient Care (SIAT) of Emilia-Romagna, an Italian region with a population of approximately 4.5 million. 5300 patients with an Injury Severity Score (ISS) >15 were admitted to the regional ICUs and recorded in the Regional Severe Trauma Registry between 2007 and 2012. Patients were classified by the Abbreviated Injury Score as follows: (1) traumatic brain injury (2) multiple injuriesand (3) extracranial lesions. The SIATs were divided into those with at least one neurosurgical level II trauma centre (TC) and those with a neurosurgical unit in the level I TC only. A higher proportion of patients (out of all SIAT patients) were admitted to the level I TC at the head of the SIAT with no additional neurosurgical facilities (1083/1472, 73.6%) compared with the level I TCs heading SIATs with neurosurgical level II TCs (1905/3815; 49.9%). A similar percentage of patients were admitted to level I TCs (1905/3815; 49.9%) and neurosurgical level II TCs (1702/3815, 44.6%) in the SIATs with neurosurgical level II TCs. Observed versus expected mortality (OE) was not statistically different among the three types of centre with a neurosurgical unit; however, the best mean OE values were observed in the level I TC in the SIAT with no neurosurgical unit. The Hub and Spoke concept was fully applied in the SIAT in which neurosurgical facilities were available in the level I TC only. The performance of this system suggests that competition among level I and level II TCs in the same Trauma System reduces performance in both. The density of neurosurgical centres must be considered by public health system governors before implementing trauma systems. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The spectra of total γ-absorption in the decays of some Lutecium, Thulium and Cesium isotopes have been measured. The probabilities for level population in the decay of the isotopes have been determined. The deduced beta strength functions reveal pronounced structure. Calculations of the strength functions using the Saxon-Woods potential and the residual Gamow-Teller interaction are presented. It is shown that in β + decay of light Thulium and Cesium isotopes the strength function comprises more than 70% of the Gamow-Teller excitations with μsub(tau) = +1. This result is the first direct observation of the Gamow-Teller resonance in β + decay of nuclei with Tsub(z) > O. (orig.)

    1982-03-01

    We describe how two different modes of chiral symmetry can be seen in nuclei. In particular, it is shown that the nuclear axial charge or more precisely the O + O - , ΔT=1 transition at zero momentum transfer probe the nuclear configuration wherein the axial charge gsub(A) is effectively enhanced in nuclear medium due to soft pions, symptomatic of the Goldstone realization of chiral symmetry in the medium while the Gamow-Teller resonances probe the configuration wherein soft pions are no longer operative, suggesting an approach toward the Wigner realization of chiral symmetry. Using the celebrated Adler-Weisberger relation, it is argued that the observed approximately 50% quenching of the Gamow-Teller strength reflects the possibility that the Gamow-Teller operator sees the quarks inside the bag, blind to the Goldstone vacuum outside. Some implications on chiral phase transitions are also discussed

    Terminal duct lobular units (TDLUs) are the primary structures from which breast cancers and their precursors arise. Decreased age-related TDLU involution and elevated mammographic density are both correlated and independently associated with increased breast cancer risk, suggesting that these characteristics of breast parenchyma might be linked to a common factor. Given data suggesting that increased circulating levels of insulin-like growth factors (IGFs) factors are related to reduced TDLU involution and increased mammographic density, we assessed these relationships using validated quantitative methods in a cross-sectional study of women with benign breast disease. Serum IGF-I, IGFBP-3 and IGF-I:IGFBP-3 molar ratios were measured in 228 women, ages 40-64, who underwent diagnostic breast biopsies yielding benign diagnoses at University of Vermont affiliated centers. Biopsies were assessed for three separate measures inversely related to TDLU involution: numbers of TDLUs per unit of tissue area ("TDLU count"), median TDLU diameter ("TDLU span"), and number of acini per TDLU ("acini count"). Regression models, stratified by menopausal status and adjusted for potential confounders, were used to assess the associations of TDLU count, median TDLU span and median acini count per TDLU with tertiles of circulating IGFs. Given that mammographic density is associated with both IGF levels and breast cancer risk, we also stratified these associations by mammographic density. Higher IGF-I levels among postmenopausal women and an elevated IGF-I:IGFBP-3 ratio among all women were associated with higher TDLU counts, a marker of decreased lobular involution (P-trend = 0.009 and women with elevated mammographic density (P-interaction women with high mammographic density and limited TDLU involution, two markers that have been related to increased breast cancer risk. If confirmed in prospective studies with cancer endpoints, these data may suggest that evaluation of IGF

    CERN Multimedia

    2002-01-01

    % IS353 \\\\ \\\\ Due to its importance in fundamental physics and astrophysics, a great effort both theoretically and experimentally is devoted to study Gamow Teller (GT)-strength. The GT-strength and its distribution play a key role in late stellar evolution. During the pre-supernova core-collapse of massive stars, the electron capture and nuclear $\\beta$ -decay determine the electron-to-baryon ratio, which influences the infall dynamics and the mass of the final core. The cross-section of the charge-exchange reaction at forward angles with energies above 100~MeV is expected to be proportional to the squares of Fermi and GT matrix elements. This proportionality should provide a Q-value free method to probe the weak interaction strength and renormalization effects in nuclei. Thus charge-exchange reactions are often used to determine the experimental GT-strength. However, the connection between the GT-strength and the cross-section of the charge-exchange reaction is partially model-dependent and the question aris...

    Full Text Available Abstract. The first-forbidden transitions can play an important role in decreasing the calculated half-lives specially in environments. We calculate the allowed Gamow-Teller transitions in pn-QRPA model for even-even neutron-rich isotopes of nickel. The first forbidden transitions for even-even neutron-rich isotopes of nickel are calculated assuming the nuclei to be spherical. The Woods-Saxon potential basis has been used in our calculations. The calculated half-lives have been compared with the schematic model calculations and corresponding experimental data. Keywords: pn-QRPA approximation, Gamow-Teller, First forbidden transitions

  8. $\\beta$-delayed neutron spectroscopy of $^{130-132}$ Cd isotopes with the ISOLDE decay station and the VANDLE array

    CERN Multimedia

    We propose to use the new ISOLDE decay station and the neutron detector VANDLE to measure the $\\beta$-delayed neutron emission of N=82-84 $^{130-132}$Cd isotopes. The large delayed neutron emission probability observed in a previous ISOLDE measurement is indicative of the Gamow-Teller transitions due to the decay of deep core neutrons. Core Gamow-Teller decay has been experimentally proven in the $^{78}$Ni region for the N>50 nuclei using the VANDLE array. The spectroscopic measurement of delayed neutron emission along the cadmium isotopic chain will allow us to track the evolution of the single particle states and the shell gap.

    only up to an excitation energy of 60 MeV. Taking into account the excitation energy range from E{sub x}=10 MeV to E{sub x}=60 MeV the polarisability of the nucleus {sup 48}Ca was estimated to be α{sub D}=(2.09±0.02) fm{sup 3}. This result deviates significantly from a theoretical prediction of α{sub D}=(2.31±0.09) fm{sup 3} based on the energy density functional theory. The result of this work could further constrain the range of the parameters of the nuclear models and might give new insights on the neutron skin thickness of {sup 48}Ca as far as a theoretical prediction for the correlation between the polarisability and neutron skin thickness is available especially for the energy region investigated in this work. In the nucleus {sup 48}Ca, almost the full experimentally accessible spin-M1 strength is exhausted by a single spin-flip transition. The corresponding state is the prominent 1{sup +}-state at E{sub x}=10.22 MeV. The configuration of the nucleus {sup 48}Ca leads to nearly pure spin-flip transitions of the neutrons. In this case the isoscalar transition matrix element is as large as the isovector one. This means that the nucleus {sup 48}Ca is a reference case whereas the nucleus {sup 208}Pb is another one because its isoscalar and isovector M1 strength is well separated. The extraction of the total electromagnetic M1 strength was based on a method that had been successfully applied to Gamow-Teller transitions in other analyses in the framework of a distorted wave impulse approximation. This method allows to calculate the strength from the measured isovector cross section at θ{sub CM}=0 mainly by a single conversion factor, the so-called ''unit cross section''. The method was used for the analysis of this work assuming that isospin symmetry is given for isobars and that the unit cross section is the same for isovector spin-M1 excitations as well as for the excitations of analogue states.

    It is important to ensure that tools are valid and reliable in the context in which they are used. The development of age and country norms is part of this process. The primary aim of the present study was to examine the performance of the Food Allergy Quality of Life Questionnaire - Parent Form (FAQLQ-PF) in a countrywide American sample of children with food allergy. The secondary aim was to compare age differences in impact across 9 European countries. In a cross-sectional quantitative design, questionnaires were completed by the parents of 1029 food-allergic children (0-12 years). Participants were recruited via support groups and allergists. Data were analyzed by using multivariate analysis of variance and tests for internal consistency and validity. The average score was calculated for each age group in 15 studies in Ireland, Switzerland, the Netherlands, Spain, Portugal, Germany, Italy, Denmark, Israel, and the United Kingdom. The FAQLQ-PF has high convergent validity (child: r = 0.49, n = 695, P = .01; parent: r = 0.36, n = 696, P = .01) and discriminant validity, parent: t (719) = 4.67, P = .001 (anaphylaxis yes vs no); t (513), P = .009 (single vs multiple allergens). Internal consistency was excellent (r = 0.96). US health-related quality of life was worse than European health-related quality of life, as indicated by higher FAQLQ-PF scores in US samples. Burden increased with age in all populations. The FAQLQ-PF is appropriate for use in an American population. Findings will form the basis for further work in the development of an online manual with food allergy-normed age scores to allow for precise measurement, interpretation of scores, and comparison across countries and cultures, in clinical and research settings.

    A fully analytical description of the allowed β spectrum shape is given in view of ongoing and planned measurements. Its study forms an invaluable tool in the search for physics beyond the standard electroweak model and the weak magnetism recoil term. Contributions stemming from finite size corrections, mass effects, and radiative corrections are reviewed. Particular focus is placed on atomic and chemical effects, where the existing description is extended and analytically provided. The effects of QCD-induced recoil terms are discussed, and cross-checks were performed for different theoretical formalisms. Special attention was given to a comparison of the treatment of nuclear structure effects in different formalisms. Corrections were derived for both Fermi and Gamow-Teller transitions, and methods of analytical evaluation thoroughly discussed. In its integrated form, calculated f values were in agreement with the most precise numerical results within the aimed for precision. The need for an accurate evaluation of weak magnetism contributions was stressed, and the possible significance of the oft-neglected induced pseudoscalar interaction was noted. Together with improved atomic corrections, an analytical description was presented of the allowed β spectrum shape accurate to a few parts in 10-4 down to 1 keV for low to medium Z nuclei, thereby extending the work by previous authors by nearly an order of magnitude.

  13. Spin dipole and quadrupole resonances in 40Ca

    1989-01-01

    Angular distributions of the double differential cross section d 2 σ/dΩ dE(σ) and the spin-flip probability S nn have been measured for inclusive proton inelastic scattering from 40 Ca at 319 MeV. Excitation energies (ω) up to about 40 MeV have been investigated over the angular range from 3.5 degree to 12 degree in the laboratory (0.3 to 0.9 fm -1 ). Here, multipole decompositions of angular distributions of σS nn for the 40 Ca(rvec p,rvec p ') reaction at 319 MeV have been performed in order to compare ΔS=1 strength observed with sum rules. In contrast to the well-known quenching of Gamow-Teller and M1 resonances, the spin-dipole resonance has a total measured strength which is larger than that predicted by the energy-weighted sum rule. The spin-dipole strength distribution supports asymmetric widths predicted by calculations including 2p-2h mixing. The spin-quadrupole resonance is observed near ω=35 MeV and its total strength for ω<40 MeV estimated

    Complete text of publication follows. Spin and isospin modes in nuclei are investigated. We discuss some of the following topics. 1. Spin-dipole excitations in 12 C and 16 O are studied (1). Effects of tensor and spin-orbit interactions on the distribution of the strengths are investigated, and neutral current neutrino scattering cross sections in 16 O are obtained for heavy-flavor neutrinos from the supernovae. 2. Gamow-Teller (GT) and spin-dipole (SD) modes in 208 Bi are investigated. Quenching and fragmentation of the GT strength are discussed (2). SD excitations and electric dipole (E1) transitions between the GT and SD states are studied (3). Calculated E1 strengths are compared with the sum rule values obtained within the 1p-1h and 1p-1h + 2p-2h configuration spaces. 3. Coulomb displacement energy (CDE) of the IAS of 14 Be is calculated, and the effects of the halo on the CDE and the configuration of the halo state are investigated. 4. Spreading width of IAS and isospin dependence of the width are investigated (4). Our formula for the width explains very well the observed isospin dependence (5). (author)

  15. Nuclear chiral axial currents and applications to few-nucleon systems

    Energy Technology Data Exchange (ETDEWEB)

    Baroni, Alessandro [Old Dominion Univ., Norfolk, VA (United States)

    2017-08-01

    This Thesis is divided into three main parts. The first part discusses basic aspects of chiral effective field theory and the formalism, based on time ordered perturbation theory, used to to derive the nuclear potentials and currents from the chiral Lagrangians. The second part deals with the actual derivation, up to one loop, of the two-nucleon potential and one- and two-nucleon weak axial charge and current. In both derivations ultraviolet divergences generated by loop corrections are isolated using dimensional regularization. The resulting axial current is finite and conserved in the chiral limit, while the axial charge requires renormalization. A complete set of contact terms for the axial charge up to the relevant order in the power counting is constructed. The third part of this Thesis discusses two applications: (i) the calculation of the Gamow-Teller matrix element of tritium, used to constrain the single low-energy constant entering the axial current; (ii) the calculation of neutrino-deuteron inclusive cross sections at low energies. These results have confirmed previous predictions obtained in phenomenological approaches. These latter studies have played an important role in the analysis and interpretation of experiments at the Sudbury Neutrino Observatory.

    Kania Richard R. E.

    2016-12-01

    Full Text Available Amanda Cross is the pen name Carolyn Heilbrun used for her mystery fiction. In two of her novels she employed the theme of androgyny. She also wrote the non-fiction, 1973 Toward a Recognition of Androgyny in which she promoted androgyny as aspect of her approach to feminism, an intellectual denial of any significant differences between the sexes. While that thread of American feminism has lost favor in current feminist ideologies, matters of gender identity are rising in prominence in American social and political thought, reviving the debate on male and female roles and identities in the United States.

    The paper investigates the dynamics of price discovery for cross-listed firms and the impact of exchange rate shocks on firm value. A simple price discovery model is proposed in which prices in the home and foreign markets react to shocks on two latent prices, namely, the efficient firm value...... and the efficient exchange rate. I disentangle the effects on firm value from the exchange rate from the other determinants of a firm's cash flow. I use high-frequency data and find that a depreciation/appreciation of the home currency decreases/increases firm value. This finding is consistent with currency...... fluctuation affecting discount rates....

  5. Centroid crossing

    International Nuclear Information System (INIS)

    Swift, G.

    1990-01-01

    This paper presents an algorithm for finding peaks in data spectra. It is based on calculating a moving centroid across the spectrum and picking off the points between which the calculated centroid crosses the channel number. Interpolation can then yield a more precise peak location. This algorithm can be implemented very efficiently requiring about one addition, subtraction, multiplication, and division operation per data point. With integer data and a centroid window equal to a power of two (so that the division can be done with shifts), the algorithm is particularly suited to efficient machine language implementation. With suitable adjustments (involving only little overhead except at suspected peaks), it is possible to minimize either false peak location or missing good peaks. Extending the method to more dimensions is straightforward although interpolating is more difficult. The algorithm has been used on a variety of nuclear data spectra with great success

    We investigated the safety of the batteries and power units used in insulin pumps in Japan. A self-administered questionnaire was sent to the 201 members of the Association for Innovative Diabetes Treatment in Japan. A total of 56 members responded, and among the 1,499 active devices, 66 had episodes of trouble related to the batteries and power units. The ratio of reported troubles to the number of insulin pumps was significantly higher in insulin pumps with a continuous glucose monitoring sensor compared with insulin pumps without a continuous glucose monitoring sensor (odds ratio 2.82, P pump (21.2%) and leakage of the battery fluid (4.5%) followed. A total of 53.2% of the reported insulin pumps needed to be replaced, and 37.1% of them recovered after replacement of the battery. As trouble related to the batteries and power units of insulin pumps was frequent, practical guidance should be provided to respective patients regarding the use of reliable batteries, and to be well prepared for unexpected insulin pump failure. © 2017 The Authors.

    Original detector unit of the Instituut voor Kernfysisch Onderzoek (IKO) BOL project. This detector unit shows that silicon detectors for nuclear physics particle detection were already developed and in use in the 1960's in Amsterdam. Also the idea of putting 'strips' onto the silicon for high spatial resolution of a particle's impact on the detector were implemented in the BOL project which used 64 of these detector units. The IKO BOL project with its silicon particle detectors was designed, built and operated from 1965 to roughly 1977. Detector Unit of the BOL project: These detectors, notably the ‘checkerboard detector’, were developed during the years 1964-1968 in Amsterdam, The Netherlands, by the Natuurkundig Laboratorium of the N.V. Philips Gloeilampen Fabrieken. This was done in close collaboration with the Instituut voor Kernfysisch Onderzoek (IKO) where the read-out electronics for their use in the BOL Project was developed and produced.

  13. Cross-border utilization of health care services by United States residents living near the Mexican border Utilización transfronteriza de los servicios de salud por residentes en los Estados Unidos que viven cerca de la frontera con México

    Full Text Available OBJECTIVES: To determine what proportion of El Paso (Texas, United States of America residents access health care services in Mexico, which services they use, and why they cross for care. METHODS: A cross-sectional, telephone survey of El Paso County residents was conducted from October-November 2007 to determine use of health care services in Mexico. At total of 2560 telephone interviews were completed. Descriptive statistics and Chi-square analysis were used to determine the proportion crossing the US-Mexico border for care and identify correlates of crossing. RESULTS: The proportion of El Paso residents that had crossed into Mexico for some type of health care service during the two years prior to the survey interview was 32.5%. Of border crossers, 27.1% used health services; 63.2%, dental services; 82.0%, pharmacy; and 9.8%, traditional healers. Reasons given were cost, lack of health insurance, language barriers, and convenience. Hispanic ethnicity, having lived in Ciudad Juárez, being uninsured, and younger age were associated with crossing. The majority were satisfied with the health services received. CONCLUSIONS: Crossing the border to access health care services in Mexico is not uncommon for US residents living in El Paso County, Texas. Given the high rate of uninsured in the United States and the increasingly stringent security requirements, health policies may be needed that allow for cross-border care, making use of this alternative health care system easier and safer.OBJETIVOS: Determinar la proporción de habitantes de El Paso (Texas, Estados Unidos de América que acceden a los servicios de salud de México, los servicios utilizados y las razones para buscar atención del otro lado de la frontera.

  17. The pCS20 PCR assay for Ehrlichia ruminantium does not cross-react with the novel deer ehrlichial agent found in white-tailed deer in the United States of America

    Directory of Open Access Journals (Sweden)

    S.M. Mahan

    2004-11-01

    Full Text Available White-tailed deer are susceptible to heartwater (Ehrlichia [Cowdria] ruminantium infection and are likely to suffer high mortality if the disease spreads to the United States. It is vital, therefore, to validate a highly specific and sensitive detection method for E. ruminantium infection that can be reliably used in testing white-tailed deer, which are reservoirs of antigenically or genetically related agents such as Ehrlichia chaffeensis, Anaplasma (Ehrlichia phagocytophilum (HGE agent and Ehrlichia ewingii. Recently, a novel but as yet unnamed ehrlichial species, the white-tailed deer ehrlichia (WTDE, has been discovered in deer populations in the United States. Although the significance of WTDE as a pathogen is unknown at present, it can be distinguished from other Ehrlichia spp. based on 16S rRNA gene sequence analysis. In this study it was differentiated from E. ruminantium by the use of the pCS20 PCR assay which has high specificity and sensitivity for the detection of E. ruminantium. This assay did not amplify DNA from the WTDE DNA samples isolated from deer resident in Florida, Georgia and Missouri, but amplified the specific 279 bp fragment from E. ruminantium DNA. The specificity of the pCS20 PCR assay for E. ruminantium was confirmed by Southern hybridization. Similarly, the 16S PCR primers (nested that amplify a specific 405-412 bp fragment from the WTDE DNA samples, did not amplify any product from E. ruminantium DNA. This result demonstrates that it would be possible to differentiate between E. ruminantium and the novel WTDE agent found in white tailed deer by applying the two respective PCR assays followed by Southern hybridizations. Since the pCS20 PCR assay also does not amplify any DNA products from E. chaffeensis or Ehrlichia canis DNA, it is therefore the method of choice for the detection of E. ruminantium in these deer and other animal hosts.

    Our objective was to compare obesity prevalence among human immunodeficiency virus (HIV)-infected adults receiving care and the U.S. general population and identify obesity correlates among HIV-infected men and women.Cross-sectional data was collected in 2009 to 2010 from 2 nationally representative surveys: Medical Monitoring Project (MMP) and National Health and Nutrition Examination Survey (NHANES).Weighted prevalence estimates of obesity, defined as body mass index ≥30.0 kg/m, were compared using prevalence ratios (PR, 95% confidence interval [CI]). Correlates of obesity in HIV-infected adults were examined using multivariable logistic regression.Demographic characteristics of the 4006 HIV-infected adults in MMP differed from the 5657 adults from the general U.S. population in NHANES, including more men (73.2% in MMP versus 49.4% in NHANES, respectively), black or African Americans (41.5% versus 11.6%), persons with annual incomes obese (PR 0.5, CI 0.5-0.6) and HIV-infected women were more likely to be obese (PR1.2, CI 1.1-1.3) compared with men and women in the general population, respectively. Among HIV-infected women, younger age was associated with obesity (60 years). Among HIV-infected men, correlates of obesity included black or African American race/ethnicity, annual income >$20,000 and 200 cells/μL.Obesity is common, affecting 2 in 5 HIV-infected women and 1 in 5 HIV-infected men. Correlates of obesity differ for HIV-infected men and women; therefore, different strategies may be needed for the prevention and treatment.

    Full Text Available Abstract Background Violence is frequent towards nurses in forensic mental health hospitals. Implications of this high risk environment have not been systematically explored. This paper explores occurrence of symptoms on post traumatic stress and their relationship to professional quality of life. Methods Self report questionnaires assessing symptoms of post traumatic stress and professional quality of life were distributed among psychiatric nurses in a high security forensic psychiatric unit with high frequency of violent behaviour. Relationships between post traumatic stress symptoms, forensic nursing experience, type of ward and compassion satisfaction, burnout and compassion fatigue were explored. Results The prevalence of post traumatic stress symptoms was low. Low scores were found on compassion satisfaction. Length of psychiatric nursing experience and low scores on compassion satisfaction were correlated to increased post traumatic stress symptoms. Conclusion Although high violence frequency, low rate of post traumatic stress symptoms and low compassion satisfaction scores was found. High staff/patient ratio and emotional distance between staff and patients are discussed as protective factors.

    Since their debut in 1987, snakes (active contour models) have become a standard image analysis technique with several variants now in common use. We present a framework called "United Snakes", which has two key features. First, it unifies the most popular snake variants, including finite difference, B-spline, and Hermite polynomial snakes in a consistent finite element formulation, thus expanding the range of object modeling capabilities within a uniform snake construction process. Second, it embodies the idea that the heretofore presumed competing technique known as "live wire" or "intelligent scissors" is in fact complementary to snakes and that the two techniques can advantageously be combined by introducing an effective hard constraint mechanism. The United Snakes framework amplifies the efficiency and reproducibility of the component techniques, and it offers more flexible interactive control while further minimizing user interactions. We apply United Snakes to several different medical image analysis tasks, including the segmentation of neuronal dendrites in EM images, dynamic chest image analysis, the quantification of growth plates in MR images and the isolation of the breast region in mammograms, demonstrating the generality, accuracy and robustness of the tool.

End values of the elements which are arranged along a beam path are read by storage tubes and added, in order to obtain pseudo boundary values which can then be compared with corresponding real boundary values. By returning the fault signal to the storage tubes, iteration is possible. Suitable storage tubes, black diagrams for data processing as well as suitable means to indicate the output signals derived from the storage tubes are given. (ORU/LH) [de

    Full Text Available Abstract Background In a multi-unit housing (MUH complex, secondhand smoke (SHS can pass from one living space to another. The aim of this study was to determine the prevalence of SHS incursion, and to establish the relationship between SHS incursion and socio-demographic and built environmental factors in MUH in Korea. Methods A population-based sample of 2600 residents (aged ≥19 years living in MUH from across the city of Seoul, Korea, was obtained through a web-based selection panel. The residents completed a questionnaire detailing socio-demographic factors, smoking status, frequency of SHS incursion, and built environmental factors. The presence of a personal smoke-free home rule was determined by residents declaring that no one smoked inside the home. Results Of the 2600 participants, non-smoking residents who lived in homes with a personal smoke-free rule were selected for further analysis (n = 1784. In the previous 12 months, 74.7% of residents had experienced SHS incursion ≥1 times. A multivariate ordinal logistic regression analysis indicated that residents who spent more time at home, lived with children, supported the implementation of smoke-free regulations in MUH, lived in small homes, lived in homes with natural ventilation provided by opening a front door or the windows and front door, and lived in homes with more frequent natural ventilation were more likely to report SHS incursion into their homes. Conclusions The majority of the non-smoking residents experienced SHS incursion, even with a personal smoke-free rule in their homes. A smoke-free policy in MUH is needed to protect residents from SHS exposure when they are at home.

    For several years, EDs in the UK NHS have faced considerable increases in attendance rates. Walk-in centres (WiCs) and minor injuries units (MIUs) have been suggested as solutions. We aimed to investigate the associations between practice and practice population characteristics with ED attendance rates or combined ED/WiC/MIU attendance, and the associations between WiC/MIU and ED attendance. We used general practice-level data including 7462 English practices in 2012/2013 and present adjusted regression coefficients from linear multivariable analysis for relationships between patients' emergency attendance rates and practice characteristics. Every percentage-point increase in patients reporting inability to make an appointment was associated with an increase in emergency attendance by 0.36 (95% CI 0.06 to 0.66) per 1000 population. Percentage-point increases in patients unable to speak to a general practitioner (GP)/nurse within two workdays and patients able to speak often to their preferred GP were associated with increased emergency attendance/1000 population by 0.23 (95% CI 0.05 to 0.42) and 0.10 (95% CI 0.00 to 0.19), respectively. Practices in areas encompassing several towns (conurbations) had higher attendance than rural practices, as did practices with more non-UK-qualified GPs. Practice population characteristics associated with increased emergency attendance included higher unemployment rates, higher percentage of UK whites and lower male life expectancy, which showed stronger associations than practice characteristics. Furthermore, higher MIU or WiC attendance rates were associated with lower ED attendance rates. Improving availability of appointments and opportunities to speak a GP/nurse at short notice might reduce ED attendance. Establishing MIUs and WiCs might also reduce ED attendance.

    A positive patient safety culture (PSC) is one of the most critical components to improve healthcare quality and safety. The Hospital Survey on Patient Safety Culture (HSOPS), developed by the US Agency for Healthcare Research and Quality, has been used to assess PSC in 31 countries. However, little is known about the impact of nurse working hours on PSC. We hypothesized that long nurse working hours would deteriorate PSC, and that the deterioration patterns would vary between countries. Moreover, the common trends observed in Japan, the US and Chinese Taiwan may be useful to improve PSC in other countries. The purpose of this study was to clarify the impact of long nurse working hours on PSC in Japan, the US, and Chinese Taiwan using HSOPS. The HSOPS questionnaire measures 12 sub-dimensions of PSC, with higher scores indicating a more positive PSC. Odds ratios (ORs) were calculated using a generalized linear mixed model to evaluate the impact of working hours on PSC outcome measures (patient safety grade and number of events reported). Tukey's test and Cohen's d values were used to verify the relationships between nurse working hours and the 12 sub-dimensions of PSC. Nurses working ≥60 h/week in Japan and the US had a significantly lower OR for patient safety grade than those working Japan and Chinese Taiwan. Patient safety grade deteriorated and the number of events reported increased with long working hours. Among the 12 sub-dimensions of PSC, long working hours had an impact on 'staffing' and 'teamwork within units' in Japan, the US and Chinese Taiwan.

    Full Text Available Abstract Background Reasons for the excess risk for cardiovascular disease among people with chronic obstructive pulmonary disease remain unclear. Our objective was to examine the cardiovascular risk profile for adults with obstructive and restrictive impairments of lung functioning in a representative sample of adults from the United States. Methods We used data from adults aged 20–79 years who participated in the National Health and Nutrition Examination Survey from 2007 to 2010 and had a pulmonary function test. The severity of obstructive impairment was defined by adapting the Global Initiative for Chronic Obstructive Lung Disease criteria. Results Among 7249 participants, 80.9% had a normal pulmonary function test, 5.7% had a restrictive impairment, 7.9% had mild obstructive impairment, and 5.5% had moderate or severe/very severe obstructive impairment. Participants with obstructive impairment had high rates of smoking and increased serum concentrations of cotinine. Compared to participants with normal pulmonary functioning, participants with at least moderate obstructive impairment had elevated concentrations of C-reactive protein but lower concentrations of total cholesterol and non-high-density lipoprotein cholesterol. Among participants aged 50–74 years, participants with at least a moderate obstructive impairment or a restrictive impairment had an elevated predicted 10-year risk for cardiovascular disease. Conclusions The high rates of smoking among adults with impaired pulmonary functioning, particularly those with obstructive impairment, point to a need for aggressive efforts to promote smoking cessation in these adults. In addition, adults with restrictive impairment may require increased attention to and fine-tuning of their cardiovascular risk profile.

  11. Preferences for care towards the end of life when decision-making capacity may be impaired: A large scale cross-sectional survey of public attitudes in Great Britain and the United States.

    Full Text Available There is continuing public debate about treatment preferences at the end of life, and the acceptability and legal status of treatments that sustain or end life. However, most surveys use binary yes/no measures, and little is known about preferences in neurological disease when decision-making capacity is lost, as most studies focus on cancer. This study investigates changes in public preferences for care towards the end of life, with a focus on measures to sustain or end life.Large-scale international public opinion surveys using a six-stage patient vignette, respondents chose a level of intervention for each stage as health and decision-making capacity deteriorated. Cross-sectional representative samples of the general public in Great Britain and the USA (N = 2016. Primary outcome measure: changes in respondents' preferences for care, measured on a four-point scale designed before data collection. The scale ranged from: maintaining life at all costs; to intervention with agreement; to no intervention; to measures for ending life.There were no significant differences between GB and USA. Preference for measures to sustain life at all costs peaked at short-term memory loss (30.2%, n = 610. Respondents selecting 'measures to help me die peacefully' increased from 3.9% to 37.0% as the condition deteriorated, with the largest increase occurring when decision-making capacity was lost (10.3% to 23.0%. Predictors of choosing 'measures to help me die peacefully' at any stage were: previous personal experience (OR = 1.34, p<0.010, and older age (OR = 1.09 per decade, p<0.010. Negative predictors: living with children (OR = 0.72, p<0.010 and being of "black" race/ethnicity (OR = 0.45, p<0.001.Public opinion was uniform between GB and USA, but markedly heterogeneous. Despite contemporaneous capacitous consent providing an essential legal safeguard in most jurisdictions, there was a high prevalence of preference for "measures to end my life peacefully" when

    Social and spatial factors are an important part of individual and community health. The objectives were to identify food establishment sub-types and evaluate prevalence of diabetes, obesity, and recommended fruit and vegetable consumption in relation to these sub-types in the Washington DC metropolitan area. A cross-sectional study design was used. A measure of retail food environment was calculated as the ratio of number of sources of unhealthier food options (fast food, convenience stores, and pharmacies) to healthier food options (grocery stores and specialty food stores). Two categories were created: ≤ 1.0 (healthier options) and > 1.0 (unhealthier options). k-means clustering was used to identify clusters based on proportions of grocery stores, restaurants, specialty food, fast food, convenience stores, and pharmacies. Prevalence data for county-level diabetes, obesity, and consumption of five or more fruits or vegetables per day (FV5) was obtained from the Behavioral Risk Factor Surveillance System. Multiple imputation was used to predict block-group level health outcomes with US Census demographic and economic variables as the inputs. The healthier options category clustered into three sub-types: 1) specialty food, 2) grocery stores, and 3) restaurants. The unhealthier options category clustered into two sub-types: 1) convenience stores, and 2) restaurants and fast food. Within the healthier options category, diabetes prevalence in the sub-types with high restaurants (5.9 %, p = 0.002) and high specialty food (6.1 %, p = 0.002) was lower than the grocery stores sub-type (7.1 %). The high restaurants sub-type compared to the high grocery stores sub-type had significantly lower obesity prevalence (28.6 % vs. 31.2 %, p obesity, or higher FV5 prevalence across the two sub-types. However, restaurants (including fast food) sub-type was significantly associated with lower diabetes and obesity, and higher FV prevalence compared to grocery store sub-type. These

    Three oral anticoagulants have reported study results for stroke prevention in patients with atrial fibrillation (AF) (dabigatran etexilate, rivaroxaban and apixaban); all demonstrated superiority or non-inferiority compared with warfarin (RE-LY, ARISTOTLE and ROCKET-AF). This study aimed to assess the representativeness for the real-world AF population, particularly the population eligible for anticoagulants. A cross-sectional database analysis. Dataset derived from the General Practice Research Database (GPRD). PRIMARY AND SECONDARY OUTCOMES MEASURE: The proportion of real-world patients with AF who met the inclusion/exclusion criteria for RE-LY, ARISTOTLE and ROCKET-AF were compared. The results were then stratified by risk of stroke using CHADS(2) and CHA(2)DS(2)-VASc. 83 898 patients with AF were identified in the GPRD. For the population at intermediate or high risk of stroke and eligible for anticoagulant treatment (CHA(2)DS(2)-VASc ≥1; n=78 783 (94%)), the proportion eligible for inclusion into RE-LY (dabigatran etexilate) was 68% (95% CI 67.7% to 68.3%; n=53 640), compared with 65% (95% CI 64.7% to 65.3%; n=51 163) eligible for ARISTOTLE (apixaban) and 51% (95% CI 50.7% to 51.4%; n=39 892) eligible for ROCKET-AF (rivaroxaban). Using the CHADS(2) method of risk stratification, for the population at intermediate or high risk of stroke and eligible for anticoagulation treatment (CHADS(2) ≥1; n=71 493 (85%)), the proportion eligible for inclusion into RE-LY was 74% (95% CI 73.7% to 74.3%; n=52 783), compared with 72% (95% CI 71.7% to 72.3%; n=51 415) for ARISTOTLE and 56% (95% CI 55.6% to 56.4%; n=39 892) for ROCKET-AF. Patients enrolled within RE-LY and ARISTOTLE were more reflective of the 'real-world' AF population in the UK, in contrast with patients enrolled within ROCKET-AF who were a more narrowly defined group of patients at higher risk of stroke. Differences between trials should be taken into account when considering the applicability of findings

    Critically ill patients suffering from fecal incontinence have a major risk of developing incontinence-associated dermatitis (IAD). The presence of moisture and digestive enzymes (lipase, protease) negatively influences skin barrier function. Additional risk factors will make some patients even more vulnerable than others. In order to provide (cost) effective prevention, this specific patient population should be identified timely. To identify independent risk factors for the development of IAD category 2 (skin loss) in critically ill patients with fecal incontinence. A cross-sectional observational study. The study was performed in 48 ICU wards from 27 Belgian hospitals. Patients of 18 years or older, with fecal incontinence at the moment of data collection, were eligible to participate. Patients with persistent skin redness due to incontinence (IAD category 1) were excluded. Potential risk factors were carefully determined based on literature and expert consultations. Data were collected over a period of eight months by trained researchers using patient records and observation of skin care practices. At the time a patient was included in the study, all relevant data from the past six days, or since admission at the ICU, were recorded. Simultaneously, direct skin observations were performed and high definition photographs were ratified by an expert IAD researcher. A multiple binary logistic regression model was composed to identify independent risk factors. Variables with P fit. The sample comprised of 206 patients, of which 95 presented with IAD category 2, and 111 were free of IAD. Seven independent risk factors were identified: liquid stool [odds ratio (OR) 4.69; 95% confidence interval (CI) 2.28-9.62], diabetes (OR 2.89; 95% CI 1.34-6.27), age (OR 1.05; 95% CI 1.02-1.08), smoking (OR 2.67; 95% CI 1.21-5.91), non-use of diapers (OR 2.97; 95% CI 1.39-6.33), fever (OR 2.60; 95% CI 1.23-5.53), and low oxygen saturation (OR 2.15; 95% CI 1.03-4.48).

    Full Text Available Abstract Background Smoke-free policy aims to protect the health of the population by reducing exposure to environmental tobacco smoke (ETS, and World Health Organisation (WHO guidance notes that these policies are only successful if there is full and proper enforcement. We aimed to investigate the problem of resistance to smoking restrictions and specifically compliance with smoke-free policy. We hypothesised that an explanation for non-compliance would lie in a measurable difference between the smoking behaviours of compliant and non-compliant smokers, specifically that non-compliance would be associated with nicotine dependence and different reasons for smoking. Methods We conducted a questionnaire-based, descriptive, cross-sectional study of hospital employees. Seven hundred and four members of staff at Addenbrooke's Hospital, Cambridge, UK, completed the questionnaire, of whom 101 were smokers. Comparison between compliant and non-compliant smokers was made based on calculated scores for the Fagerström test and the Horn-Waingrow scale, and level of agreement with questions about attitudes. For ordinal data we used a linear-by-linear association test. For non-parametric independent variables we used the Mann-Whitney test and for associations between categorical variables we used the chi-squared test. Results The demographic composition of respondents corresponded with the hospital's working population in gender, age, job profile and ethnicity. Sixty nine smokers reported they were compliant while 32 were non-compliant. Linear-by-linear association analysis of the compliant and non-compliant smokers' answers for the Fagerström test suggests association between compliance and nicotine dependence (p = 0.049. Mann-Whitney test analysis suggests there is a statistically significant difference between the reasons for smoking of the two groups: specifically that non-compliant smokers showed habitual smoking behaviour (p = 0.003.

    Full Text Available This article examines the earnings quality of French firms cross-listed in the United States and United Kingdom, and non-cross-listed French firms. We examined the quality of financial reporting based on measures of earnings management, timely loss recognition (TLR, and price-earnings association. We found that both cross-listings and non-cross-listings show significant earnings smoothing activities and tend to use accruals to manage earnings, and are not timely in loss recognition. We surmise that cross-listing in the United States or United Kingdom has not changed the accounting choices of French cross-listing firms relative to firms that are not cross-listed. However, our findings show that the market considers earnings and book value data of cross-listing firms to be more informative than those of non-cross-listing firms.

    Full Text Available This paper presents and discusses an integrated set of policies designed to reduce U.S. carbon emissions over the next four decades. This innovation path also aims to promote environmental quality, particularly by reducing emissions of criteria air pollutants, to reduce U.S. dependence on imported oil, and to induce technological innovation and diffusion in energy production and consumption. The innovation path would reduce economy-wide carbon emissions by 26% below baseline projections for 2010 and by 62% below baseline projections for 2030; this translates into 10% below 1990 levels in 2010 and 45% below 1990 levels in 2030. Emissions of criteria pollutants also would be significantly reduced, as would petroleum imports by the United States. Moreover, the innovation path would yield cumulative net savings for the United States of $218 billion (1993 dollars through 2010, or $19 billion on a leveled annual basis, and would result in 800,000 additional jobs nationwide by 2010. Although the overall findings from the innovation path analysis are robust, the results should be taken as indicative, rather than precisely predictive, owing to uncertainties in future costs, prices, technology performance, and consumer behavior.

    1991-03-01

    This report summarizes the study of various longitudinal problems pertaining to the transition-energy crossing in the proposed Relativistic Heavy Ion Collider. Scaling laws are provided for the effects of chromatic non-linearity, self-field mismatch, and microwave instability. It is indicated that the beam loss and bunch-area growth are mainly caused by the chromatic non-linear effect, which is enhanced by the space-charge force near transition. Computer simulation using the program TIBETAN shows that a ''γ T -jump'' of about 0.8 unit within a time period of 60 ms is adequate to achieve a ''clean'' crossing, provided that the remnant voltage of the 160 MHz rf system is less than 10 kV. 13 refs., 5 figs

  3. Precision measurements in the weak interaction framework: development of realistic simulations for the LPCTrap device installed at GANIL

    International Nuclear Information System (INIS)

    Fabian, Xavier

    2015-01-01

    This work belongs to the effort presently deployed to measure the angular correlation parameter a βν in three nuclear beta decays ( 6 He + , 35 Ar + and 19 Ne + ). The V-A structure of the weak interaction implies that a βν = +1 for a pure Fermi transition and a βν = -1/3 for a pure Gamow-Teller transition. A thorough measurement of this parameter to check any deviation from these values may lead to the discovery of possible exotic currents. Furthermore, the measurement of a βν in mirror transitions allows the extraction of V ud , the first element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The LPCTrap apparatus, installed at GANIL, is designed to ready a continuous ion beam for injection in a dedicated Paul trap. This latter device allows to have a quasi-punctual source from which the decay products are detected in coincidence. It is from the study of the recoil ion time-of-flight (TOF) distribution that a βν is withdrawn and, since 2010, the associated Shake-Off (SO) probabilities. This study requires the complete simulation of the LPCTrap experiments. The major part of this work is dedicated to such simulations, especially to the modeling of the trapped ion cloud dynamic. The Clouda program, which takes advantage of graphics processing unit (GPU), was developed in this context and its full characterization is presented here. Three important aspects are addressed: the electromagnetic trapping field, the realistic collisions between the ions and the buffer gas atoms and the space charge effect. The present work shows the importance of these simulations to increase the control of the systematic errors on a βν . (author) [fr

  14. Measurement of weak rates for stellar evolution via the (t,3He) reaction

    International Nuclear Information System (INIS)

    Zegers, R.G.T.

    2007-01-01

    The (t, 3 He) charge-exchange reaction has been developed as a tool to extract Gamow-Teller strengths on nuclei of importance for stellar evolution. A secondary triton beam of 115 MeV/nucleon is used, either produced from a primary α beam, or, since recently, from a primary 16 O beam. Here, the (t, 3 He) reaction is used to study the Gamow-Teller strength distribution in 58 Co via the 58 Ni(t, 3 He) reaction. The experimental results are compared with calculations in large-scale shell models using the kb3g and gxpf1 interactions, as well as existing data from 58 Ni(n, p) and 58 Ni(d, 2 He) experiments. The differences between the data and theoretical models are studied in terms of electron-capture rates in the pre-collapse stages of core-collapse supernovae

    1990-01-01

    This report summarizes the study of various longitudinal problems pertaining to the transition-energy crossing in the proposed Fermi Lab Main Injector. The theory indicates that the beam loss and bunch-area growth are mainly caused by the chromatic non-linear effect, which is enhanced by the space-charge force near transition. Computer simulation using the program TIBETAN shows that a ''γ T jump'' of about 1.5 unit within 1 ms is adequate to achieve a ''clean'' crossing in the currently proposed h=588 scenario. 19 refs., 4 figs

    Good fits to the magnetic moments of /sup 3/He and /sup 3/H are obtained when the nucleonic bags consisting of 3-quarks each are assumed to be deformed. Gamow-Teller strengths as well magnetic dipole strengths residing in the low energy and the ..delta.. - sectors are obtained. If, as manifested in the EMC effect, the bags expand in the nuclear medium, then the net deformation of a bag must also decrease in nuclei.

    Within the framework of a constituent quark model we derive energy-weighted sum rules for strangeness exchange (analog) and spin-strangeness exchange (generalized Gamow-Teller) reactions in the limit of small momentum transfer. The target nucleus is treated as a system of non-communicating 3-quark clusters. We also calculate the branching between the SU(3) octet and decouplet channels and we consider double strangeness exchange reactions. (orig.)

  5. Cross-Linking Studies of Lysozyme Nucleation

    Forsythe, Elizabeth; Pusey, Marc

    2000-01-01

    Tetragonal chicken egg white crystals consist of 4(sub 3) helices running in alternating directions, the helix rows having a two fold symmetry with each other. The unit cell consists of one complete tetrameric turn from each of two adjacent helices (an octamer). PBC analysis indicates that the helix intermolecular bonds are the strongest in the crystal, therefore likely formed first. AFM analysis of the (110) surface shows only complete helices, no half steps or bisected helices being found, while AFM line scans to measure the growth step increments show that they are multiples of the 4(sub 3) helix tetramer dimensions. This supports our thesis that the growth units are in fact multiples of the four molecule 4(sub 3) helix unit, the "average" growth unit size for the (110) face being an octamer (two turns about the helix) and the (101) growth unit averaging about the size of a hexamer. In an effort to better understand the species involved in the crystal nucleation and growth process, we have initiated an experimental program to study the species formed in solution compared to what is found in the crystal through covalent cross-linking studies. These experiments use the heterobifunctional cross-linking agent aminoethyl-4-azidonitroanaline (AEANA). An aliphatic amine at one end is covalently attached to the protein by a carbodiimide-mediated reaction, and a photo reactive group at the other can be used to initiate crosslinking. Modifications to the parent structure can be used to alter the distance between the two reactive groups and thus the cross-linking agents "reach". In practice, the cross-linking agent is first coupled to the asp101 side chain through the amine group. Asp101 lies within the active site cleft, and previous work with fluorescent probes had shown that derivatives at this site still crystallize in the tetragonal space group. This was also found to be the case with the AEANA derivative, which gave red tetragonal crystals. The protein now has a

    2014-01-01

    Full Text Available The paper displays the application of the Cross-Impact method in pedagogy, namely a methodological approach which crosses variables in a novel, but statistically justified manner. The method is an innovation in pedagogy as well as in research methodology of social and psychological phenomena. Specifically, events and processes are crossed, that is, experts' predictions of about future interaction of events and processes. Therefore, this methodology is futuristic; it concerns predicting future, which is of key importance for pedagogic objectives. The paper presents two instances of the cross-impact approach: the longer, displayed in fourteen steps, and the shorter, in four steps. They are both accompanied with mathematic and statistical formulae allowing for quantification, that is, a numerical expression of the probability of a certain event happening in the future. The advantage of this approach is that it facilitates planning in education which so far has been solely based on lay estimates and assumptions.

    Cross-subsidization arises naturally when firms with different comparative ad- vantages compete for consumers with diverse shopping patterns. Firms then face a form of co-opetition, being substitutes for one-stop shoppers and complements for multi-stop shoppers. Competition for one-stop shoppers then drives total prices down to cost, but firms subsidize weak products with the profit made on strong products. While firms and consumers would benefit from cooperation limiting cross- subsidization...

    Appropriate pricing for medical services of not-for-profit hospital is necessary. The prices should be fair to the public and should be high enough to cover the operative costs of the organization. The purpose of this study was to determine the cost and unit cost of medical services performed at the Mohs and Dermasurgery Unit (MDU), Department of Dermatology, The University of Texas-MD Anderson Cancer Center, Houston, TX from the healthcare provider's perspective. MDU costs were retrieved from the Financial Department for fiscal year 2006. The patients' statistics were acquired from medical records for the same period. Unit cost calculation was based on the official method of hospital accounting. The overall unit cost for each patient visit was $673.99 United States dollar (USD). The detailed unit cost of nurse visit, new patient visit, follow-up visit, consultation, Mohs and non-Mohs procedure were, respectively, $368.27, $580.09, $477.82, $585.52, $1,086.12 and $858.23 USD. With respect to a Mohs visit, the unit cost per lesion and unit cost per stage were $867.89 and $242.30 USD respectively. Results from this retrospective study provide information that may be used for pricing strategy and resource allocation by the administrative board of MDU.

    To evaluate and compare stressors identified by patients of a coronary intensive care unit with those perceived by patients of a general postoperative intensive care unit. This cross-sectional and descriptive study was conducted in the coronary intensive care and general postoperative intensive care units of a private hospital. In total, 60 patients participated in the study, 30 in each intensive care unit. The stressor scale was used in the intensive care units to identify the stressors. The mean score of each item of the scale was calculated followed by the total stress score. The differences between groups were considered significant when p intensive care unit and 53.60 ± 17.47 years in the general postoperative intensive care unit. For patients in the coronary intensive care unit, the main stressors were "being in pain", "being unable to fulfill family roles" and "being bored". For patients in the general postoperative intensive care unit, the main stressors were "being in pain", "being unable to fulfill family roles" and "not being able to communicate". The mean total stress scores were 104.20 ± 30.95 in the coronary intensive care unit and 116.66 ± 23.72 (p = 0.085) in the general postoperative intensive care unit. When each stressor was compared separately, significant differences were noted only between three items. "Having nurses constantly doing things around your bed" was more stressful to the patients in the general postoperative intensive care unit than to those in the coronary intensive care unit (p = 0.013). Conversely, "hearing unfamiliar sounds and noises" and "hearing people talk about you" were the most stressful items for the patients in the coronary intensive care unit (p = 0.046 and 0.005, respectively). The perception of major stressors and the total stress score were similar between patients in the coronary intensive care and general postoperative intensive care units.

  3. Geneticists and the biology of race crossing.

    Science.gov (United States)

    Provine, W B

    1973-11-23

    Geneticists in England and the United States clearly reversed their published remarks on the effects of race crossing between 1930 and 1950. The reversal occurred in two steps. First came the change in the 1930's from a condemnation of wide race crosses to an agnostic view. The second change, from the agnostic view to the belief that wide race crosses were at worst biologically harmless, took place during and shortly after World War II. The entire reversal occurred in the light of little new compelling data from studies of actual human race crosses. The lack of new data is unsurprising. Few geneticists wished to initiate experiments that took three human generations to complete. And controlled race crosses are hard to arrange, even with government grants. What might be more surprising was the willingness of geneticists to make such positive statements about race crossing when they had so little reliable genetic evidence. I interviewed or wrote to ten prominent geneticists who worked on human genetics between 1930 and 1950. Not one believed that new evidence on race crossing was the primary reason why geneticists changed their minds about the effects of race crossing. One plausible explanation, that the rise of "population thinking" (44) caused geneticists to change their minds, does not fit the evidence. Castle was no more of a "population" thinker than East, yet they differed radically in their conclusions about race crossing. What, then, did cause geneticists to change their minds? Most important was the revulsion of educated people in the United States and England to Nazi race doctrines and their use in justifying extermination of Jews. Few geneticists wanted to argue, as had the Nazis, that biology showed race crossing was harmful. Instead, having witnessed the horrible toll, geneticists naturally wanted to argue that biology showed race crossing was at worst harmless. No racist nation could misuse that conclusion. And geneticists did revise their biology to

    International Nuclear Information System (INIS)

    1991-01-01

    In the 14 MeV Neutron Laboratory, we have continued the development of a facility that is now the only one of its kind in operation in the United States. We have refined the klystron bunching system described in last year's report to the point that 1.2 nanosecond pulses have been directly measured. We have tested the pulse shape discrimination capability of our primary NE 213 neutron detector. We have converted the RF sweeper section of the beamline to a frequency of 1 MHz to replace the function of the high voltage pulser described in last year's report which proved to be difficult to maintain and unreliable in its operation. We have also overcome several other significant experimental difficulties, including a major problem with a vacuum leak in the main accelerator column. We have completed additional testing to prove the remainder of the generation and measurement systems, but overcoming some of these experimental difficulties has delayed the start of actual data taking. We are now in a position to begin our first series of ring geometry elastic scattering measurements, and these will be underway before the end of the current contract year. As part of our longer term planning, we are continuing the conceptual analysis of several schemes to improve the intensity of our current pulsed beam. These include the provision of a duoplasmatron ion source and/or the provision of preacceleration bunching. Additional details are given later in this report. A series of measurements were carried out at the Tandem Dynamatron Facility involving the irradiation of a series of yttrium foils and the determination of activation cross sections using absolute counting techniques. The experimental work has been completed, and final analysis of the cross section data will be completed within several months

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available Ongoing low participation of women in global leadership calls for more research in this field. In this article, we set out to include gendered expectations toward leader behavior as part of cross-cultural leadership theory. Building on an existing body of research, we focus on propositions about the effects of gendered expectations on the leader, from the followers’ standpoint. The consideration of gendered effects from the follower standpoint is an under-researched area in leadership literature, and it is even more rarely to be found in empirical data. In every culture, there are certain expectations toward leaders of the two genders that influence their behavior. In this article, we will attempt to answer the following question: How does perceived leader behavior and gendered behavior relate to national culture and actual leader behavior? We present a conceptual model that seeks to incorporate gendered expectations into cross-cultural leadership as an answer. Moreover, we provide a conceptual guideline toward operationalization of the model. The model includes the potential of dissonance between male expectations as a dominating leadership role and female leadership. This might serve as an explanation as to why in some cases women are not seen as successful as men when they adopt a masculine leadership style. The article seeks to advance cross-cultural leadership theory by focusing on expected gendered leadership behavior. Our ideas and model could eventually contribute to the advancement of leadership theory, as well as contributing to gender studies, cross-cultural leadership, and business communication.

    A characteristic of the news market is that consumers often cross-check information, i.e. observe several news outlets. At the same time, data on political media suggest that more partisan consumers are more likely to cross-check. We explore these phenomena by building a model of horizontal competition in newspaper endorsements. Without cross-checking, outlets are unbiased and minimally differentiated. When cross-checking is allowed, we show that cross-checkers are indeed more partisan than ...

  2. Visual monitoring of railroad grade crossing

    Sheikh, Yaser A.; Zhai, Yun; Shafique, Khurram; Shah, Mubarak A.

    2004-09-01

    There are approximately 261,000 rail crossings in the United States according to the studies by the National Highway Traffic Safety Administration (NHTSA) and Federal Railroad Administration (FRA). From 1993 to 1998, there were over 25,000 highway-rail crossing incidents involving motor vehicles - averaging 4,167 incidents a year. In this paper, we present a real-time computer vision system for the monitoring of the movement of pedestrians, bikers, animals and vehicles at railroad intersections. The video is processed for the detection of uncharacteristic events, triggering an immediate warning system. In order to recognize the events, the system first performs robust object detection and tracking. Next, a classification algorithm is used to determine whether the detected object is a pedestrian, biker, group or a vehicle, allowing inferences on whether the behavior of the object is characteristic or not. Due to the ubiquity of low cost, low power, and high quality video cameras, increased computing power and memory capacity, the proposed approach provides a cost effective and scalable solution to this important problem. Furthermore, the system has the potential to significantly decrease the number of accidents and therefore the resulting deaths and injuries that occur at railroad crossings. We have field tested our system at two sites, a rail-highway grade crossing, and a trestle located in Central Florida, and we present results on six hours of collected data.

  3. Cross Disciplinary Biometric Systems

    2012-01-01

    Cross disciplinary biometric systems help boost the performance of the conventional systems. Not only is the recognition accuracy significantly improved, but also the robustness of the systems is greatly enhanced in the challenging environments, such as varying illumination conditions. By leveraging the cross disciplinary technologies, face recognition systems, fingerprint recognition systems, iris recognition systems, as well as image search systems all benefit in terms of recognition performance.  Take face recognition for an example, which is not only the most natural way human beings recognize the identity of each other, but also the least privacy-intrusive means because people show their face publicly every day. Face recognition systems display superb performance when they capitalize on the innovative ideas across color science, mathematics, and computer science (e.g., pattern recognition, machine learning, and image processing). The novel ideas lead to the development of new color models and effective ...

    Esteves, E; Pinus, J; Maranhão, R F; Abib, S de C; Pinus, J

    1995-01-01

    Crossed testicular ectopia (CTE) is a rare anomaly, characterized by migration of one testis towards the opposite inguinal canal. Presented here is a case of crossed ectopia of the right testis, treated by extraperitoneal transposition of the gonad and right orchiopexy. Embriology and surgical findings suggest that CTE is a common consequence of many unclear ethiologic factors, specially mechanical ones, and can be associated with Muller duct persistence. Review of literature suggests a classification of CTE into 3 types: I--associated with inguinal hernia alone; II--associated with persistent mullerian remnants; III--associated with other anomalies without mullerian remnants. Treatment includes transeptal orchiopexy or extraperitoneal transposition of the testis, research for mullerian remnants and other anomalies, and long term postoperative follow-up, due to the risk of becoming malignant.

    Energy risk management is the principal topic of this paper. Four major subjects are examined: cross-commodity trading objectives (reduce the risk of an underlying exposure in another commodity); portfolio risk reduction (an Alberta power distributor exposed to high pool prices could protect against high pool prices through a fixed price purchase of Alberta natural gas); tailoring pricing to customer needs (sell power to the gas producer indexed to the price of gas); and (4) reducing insurance costs (rather than purchasing downside protection (puts) individually against oil and gas prices, a producer could purchase a basket option). Since the key issue in cross-commodity transactions is the estimation of correlation, it is important to be prepared to alter correlation assumptions. 1 tab., 2 figs

    1992-01-01

    From its inception, the Nuclear Data Project at the University of Michigan has concentrated on two major objectives: (1) to carry out carefully controlled nuclear measurements of the highest possible reliability in support of the national nuclear data program, and (2) to provide an educational opportunity for students with interests in experimental nuclear science. The project has undergone a successful transition from a primary dependence on our photoneutron laboratory to one in which our current research is entirely based on a unique pulsed 14 MeV fast neutron facility. The new experimental facility is unique in its ability to provide nanosecond bursts of 14 MeV neutrons under conditions that are ''clean'' and as scatter-free as possible, and is the only one of its type currently in operation in the United States. It has been designed and put into operation primarily by graduate students, and has met or exceeded all of its important initial performance goals. We have reached the point of its routine operation, and most of the data are now in hand that will serve as the basis for the first two doctoral dissertations to be written by participating graduate students. Our initial results on double differential neutron cross sections will be presented at the May 1993 Fusion Reactor Technology Workshop. We are pleased to report that, after investing several years in equipment assembly and optimization, the project has now entered its ''data production'' phase

    Many natural phenomena can only be properly understood if one has a detailed knowledge of interactions involving atoms, molecules, ions, electrons or photons. In the laboratory these processes are often studied by preparing beams of two types of particle and observing the reactions which occur when the beams intersect. Some of the more interesting of these crossed beam experiments and their results are discussed. Proposals to extend colliding beam techniques to high energy particle physics are also outlined.

  15. The crossed phrenic phenomenon

    Directory of Open Access Journals (Sweden)

    Michael George Zaki Ghali

    2017-01-01

    Full Text Available The cervical spine is the most common site of traumatic vertebral column injuries. Respiratory insufficiency constitutes a significant proportion of the morbidity burden and is the most common cause of mortality in these patients. In seeking to enhance our capacity to treat specifically the respiratory dysfunction following spinal cord injury, investigators have studied the “crossed phrenic phenomenon”, wherein contraction of a hemidiaphragm paralyzed by a complete hemisection of the ipsilateral cervical spinal cord above the phrenic nucleus can be induced by respiratory stressors and recovers spontaneously over time. Strengthening of latent contralateral projections to the phrenic nucleus and sprouting of new descending axons have been proposed as mechanisms contributing to the observed recovery. We have recently demonstrated recovery of spontaneous crossed phrenic activity occurring over minutes to hours in C1-hemisected unanesthetized decerebrate rats. The specific neurochemical and molecular pathways underlying crossed phrenic activity following injury require further clarification. A thorough understanding of these is necessary in order to develop targeted therapies for respiratory neurorehabilitation following spinal trauma. Animal studies provide preliminary evidence for the utility of neuropharmacological manipulation of serotonergic and adenosinergic pathways, nerve grafts, olfactory ensheathing cells, intraspinal microstimulation and a possible role for dorsal rhizotomy in recovering phrenic activity following spinal cord injury

    2011-05-01

    The purpose of this cross-cultural study was to explore critical thinking among nurse scholars in Thailand and the United States. The study used qualitative methodology to examine how nurse scholars describe critical thinking in nursing. Nurse educators in Thailand and the United States were questioned concerning the following aspects of critical thinking: essential components; teaching and evaluation techniques; characteristics of critical thinkers; and the importance of a consensus definition for critical thinking in nursing. Their statements, which revealed both common and specific cultural aspects of critical thinking, were subjected to content analysis. Certain themes emerged that have not been widely discussed in the literature, including the link between staying calm and thinking critically, the assertion that happiness is an essential component of critical thinking, and the participants' nearly unanimous support for coming to a consensus definition of critical thinking for nursing.

    A joint research program involving the United States and the United Kingdom was instigated about four years ago for the purpose of studying burnup of higher actinides using in-core irradiation in the fast reactor at Dounreay, Scotland. Simultaneously, determination of cross sections of a wide variety of higher actinide isotopes was proposed. Coincidental neutron flux and energy spectral measurements were to be made using vanadium encapsulated dosimetry materials in the immediate region of the burnup and cross section samples. The higher actinide samples chosen for the burnup study were 241 Am and 244 Cm in the forms of Am 2 O 3 , Cm 2 O 3 , and Am 6 Cm(RE) 7 O 21 , where (RE) represents a mixture of lanthanide sesquioxides.

. Descriptive, cross-sectional.
. Web-based survey.
. 108 oncology nurses and 44 oncologists. 
. 31-item questionnaire derived from preexisting surveys in the United States and Switzerland.
. Self-rated difficulties in taking care of culturally and linguistically diverse patients and self-rated interests in cross-cultural training.
. All respondents reported communication difficulties in encounters with culturally and linguistically diverse patients. Respondents considered the absence of written materials in other languages, absence of a shared common language with patients, and sensitive subjects (e.g., end of life, sexuality) to be particularly problematic. Respondents also expressed a high level of interest in all aspects of cross-cultural training (task-oriented skills, background knowledge, reflexivity, and attitudes). Nurses perceived several difficulties related to care of migrants as more problematic than physicians did and were more interested in all aspects of cross-cultural training. 
. The need for cross-cultural training is high among oncology clinicians, particularly among nurses.
. The results reported in the current study may help nurses in decision-making positions and educators in introducing elements of cross-cultural education into oncology curricula for nurses. Cross-cultural training should be offered to oncology nurses.

  16. Study of nuclear isovector spin responses from polarization transfer in (p,n) reactions at intermediate energies

    International Nuclear Information System (INIS)

    Wakasa, Tomotsugu

    1997-01-01

    We have measured a complete set of polarization transfer observables has been measured for quasi-free (p vector, n vector) reactions on 2 H, 6 Li, 12 C, 40 Ca, and 208 Pb at a bombarding energy of 346MeV and a laboratory scattering angle of 22deg (q=1.7 fm -1 ). The polarization transfer observables for all five targets are remarkably similar. These polarization observables yield separated spin-longitudinal (σ·q) and spin-transverse (σxq) nuclear responses. These results are compared to the spin-transverse responses measured in deep-inelastic electron scattering as well as to nuclear responses based on the random phase approximation. Such a comparison reveals an enhancement in the (p vector, n vector) spin-transverse channel, which masks the effect of pionic correlations in the response ratio. Second, the double differential cross sections at θ lab between 0deg and 12.3deg and the polarization transfer D NN at 0deg for the 90 Zr(p,n) reaction are measured at a bombarding energy of 295MeV. The Gamow-Teller(GT) strength B(GT) in the continuum deduced from the L=0 cross section is compared both with the perturbative calculation by Bertsch and Hamamoto and with the second-order random phase approximation calculation by Drozdz et al. The sum of B(GT) values up to 50MeV excitation becomes S β- =28.0±1.6 after subtracting the contribution of the isovector spin-monopole strength. This S β- value of 28.0±1.6 corresponds to about (93±5)% of the minimum value of the sum-rule 3(N-Z)=30. Last, first measurements of D NN (0deg) for (p vector, n vector) reactions at 295MeV yield large negative values up to 50MeV excitation for the 6 Li, 11 B, 12 C, 13 C(p vector, n vector) reactions. DWIA calculations using the Franey and Love (FL) 270MeV interaction reproduce differential cross sections and D NN (0deg) values, while the FL 325MeV interaction yield D NN (0deg) values less negative than the experimental values.

    CrossFit is a type of competitive exercise program that has gained widespread recognition. To date, there have been no studies that have formally examined injury rates among CrossFit participants or factors that may contribute to injury rates. To establish an injury rate among CrossFit participants and to identify trends and associations between injury rates and demographic categories, gym characteristics, and athletic abilities among CrossFit participants. Descriptive epidemiology study. A survey was conducted, based on validated epidemiologic injury surveillance methods, to identify patterns of injury among CrossFit participants. It was sent to CrossFit gyms in Rochester, New York; New York City, New York; and Philadelphia, Pennsylvania, and made available via a posting on the main CrossFit website. Participants were encouraged to distribute it further, and as such, there were responses from a wide geographical location. Inclusion criteria included participating in CrossFit training at a CrossFit gym in the United States. Data were collected from October 2012 to February 2013. Data analysis was performed using Fisher exact tests and chi-square tests. A total of 486 CrossFit participants completed the survey, and 386 met the inclusion criteria. The overall injury rate was determined to be 19.4% (75/386). Males (53/231) were injured more frequently than females (21/150; P = .03). Across all exercises, injury rates were significantly different (P CrossFit was approximately 20%. Males were more likely to sustain an injury than females. The involvement of trainers in coaching participants on their form and guiding them through the workout correlates with a decreased injury rate. The shoulder and lower back were the most commonly injured in gymnastic and power lifting movements, respectively. Participants reported primarily acute and fairly mild injuries.

    To characterize cross-cultural sleep patterns and sleep problems in a large sample of mothers of children (ages birth to 6 years) in multiple predominantly Asian and predominantly Caucasian countries. Mothers of 10,085 young children (predominantly Asian countries/regions: China, Hong Kong, India, Korea, Japan, Malaysia, Philippines, Singapore, Thailand; predominantly Caucasian countries: Australia, Canada, New Zealand, United Kingdom, United States) completed an internet-based expanded version of the Pittsburgh Sleep Quality Index. Mothers in predominantly Asian countries/regions had later bedtimes, decreased number and duration of night wakings, more nighttime sleep, and more total sleep than mothers from predominantly Caucasian countries, P Malaysia to 77.8% of mothers in Japan. Sleep disturbance symptoms were quite common, especially symptoms related to insomnia, and were more likely to be reported by mothers in predominantly Caucasian countries. However, psychosocial factors, including having children of a younger age, being unemployed, and having a lower education level were the best predictors of poor sleep, whereas culture was not a significant predictor. Overall, mothers in predominantly Asian countries/regions reported later bedtimes but sleeping better and longer than mothers from predominantly Caucasian countries, which is dissimilar to cross-cultural findings of young children. Psychosocial factors were found to be the best predictors of poor sleep, irrespective of culture. Further studies are needed to understand the impact of these findings.

    Full Text Available OBJETIVE: To estimate prevalence of type 2 diabetes (diabetes and impaired fasting glucose (IFG in the border region between the United States of America and Mexico, by ethnic origin and country of residence; identify risk factors associated with both conditions; and explore the extent to which these factors account for cross-border or ethnic disparities in prevalence. METHODS: From April 2001 to November 2002, Phase I of the U.S.-Mexico Border Diabetes Prevention and Control Project, a prevalence study of diabetes and its risk factors, was conducted at the U.S.-Mexico border using multistage cluster sampling. A questionnaire was administered on diabetes (self-reported and lifestyle and a physical examination and blood sample were obtained. A total of 4 027 adults participated in the study: 2 120 Hispanics from the Mexican side of the border and 1 437 Hispanics and 470 non-Hispanics (of whom 385 were classified as "white" from the U.S. side of the border. RESULTS: The age-adjusted prevalence of self-reported and unrecognized diabetes in Hispanics was 15.4% (16.6% on the Mexican side of the border and 14.7% on the U.S. side. The age-adjusted prevalence of IFG was similar on both sides of the border (14.1% on the Mexican side and 13.6% on the U.S. side. CONCLUSIONS: Established risk factors for diabetes (e.g., age, obesity, and family history were relevant and there was an inverse relationship between diabetes and education and socioeconomic level. While diabetes prevalence is high on both sides of the U.S.-Mexico border, one-fourth of the cases remain undiagnosed, suggesting a need for development and implementation of a public health program for prevention, diagnosis, and control of diabetes in the region.OBJETIVO: Calcular la prevalencia de la diabetes de tipo 2 (diabetes y de la alteración de la glucosa en ayunas en la zona fronteriza entre México y los Estados Unidos, por origen étnico y país de residencia; identificar los factores de

    2017-01-01

    Complexity measures for time series have been used in many applications to quantify the regularity of one dimensional time series, however many dynamical systems are spatially distributed multidimensional systems. We introduced Dynamic Cross-Entropy (DCE) a novel multidimensional complexity measure that quantifies the degree of regularity of EEG signals in selected frequency bands. Time series generated by discrete logistic equations with varying control parameter r are used to test DCE measures. Sliding window DCE analyses are able to reveal specific period doubling bifurcations that lead to chaos. A similar behavior can be observed in seizures triggered by electroconvulsive therapy (ECT). Sample entropy data show the level of signal complexity in different phases of the ictal ECT. The transition to irregular activity is preceded by the occurrence of cyclic regular behavior. A significant increase of DCE values in successive order from high frequencies in gamma to low frequencies in delta band reveals several phase transitions into less ordered states, possible chaos in the human brain. To our knowledge there are no reliable techniques able to reveal the transition to chaos in case of multidimensional times series. In addition, DCE based on sample entropy appears to be robust to EEG artifacts compared to DCE based on Shannon entropy. The applied technique may offer new approaches to better understand nonlinear brain activity. Copyright © 2016 Elsevier B.V. All rights reserved.

    2017-11-01

    First, we summarize the circumstances in which chaotic pilot-wave dynamics gives rise to quantum-like statistical behavior. For ``closed'' systems, in which the droplet is confined to a finite domain either by boundaries or applied forces, quantum-like features arise when the persistence time of the waves exceeds the time required for the droplet to cross its domain. Second, motivated by the similarities between this hydrodynamic system and stochastic electrodynamics, we examine the behavior of a bouncing droplet above the Faraday threshold, where a stochastic element is introduced into the drop dynamics by virtue of its interaction with a background Faraday wave field. With a view to extending the dynamical range of pilot-wave systems to capture more quantum-like features, we consider a generalized theoretical framework for stochastic pilot-wave dynamics in which the relative magnitudes of the drop-generated pilot-wave field and a stochastic background field may be varied continuously. We gratefully acknowledge the financial support of the NSF through their CMMI and DMS divisions.

    Kagawa, A.

    2013-12-01

    Over the last few decades, the United Nations (UN) has been approached by Security Council and Member States on international boundary issues. The United Nations regards the adequate delimitation and demarcation of international boundaries as a very important element for the maintenance of peace and security in fragile post-conflict situations, establishment of friendly relationships and cross-border cooperation between States. This paper will present the main principles and framework the United Nations applies to support the process of international boundary delimitation and demarcation activities. The United Nations is involved in international boundary issues following the principle of impartiality and neutrality and its role as mediator. Since international boundary issues are multi-faceted, a range of expertise is required and the United Nations Secretariat is in a good position to provide diverse expertise within the multiple departments. Expertise in different departments ranging from legal, political, technical, administrative and logistical are mobilised in different ways to provide support to Member States depending on their specific needs. This presentation aims to highlight some of the international boundary projects that the United Nations Cartographic Section has been involved in order to provide the technical support to different boundary requirements as each international boundary issue requires specific focus and attention whether it be in preparation, delimitation, demarcation or management. Increasingly, the United Nations is leveraging geospatial technology to facilitate boundary delimitation and demarcation process between Member States. Through the presentation of the various case studies ranging from Iraq - Kuwait, Israel - Lebanon (Blue Line), Eritrea - Ethiopia, Cyprus (Green Line), Cameroon - Nigeria, Sudan - South Sudan, it will illustrate how geospatial technology is increasingly used to carry out the support.

    2014-10-01

    Prior research has found that safety organizing behaviors of registered nurses (RNs) positively impact patient safety. However, little research exists on how engaging in safety organizing affects caregivers. While we know that organizational processes can have divergent effects on organizational and employee outcomes, little research exists on the effects of pursuing highly reliable performance through safety organizing on caregivers. Specifically, we examined whether, and the conditions under which, safety organizing affects RN emotional exhaustion and nursing unit turnover rates. Subjects included 1352 RNs in 50 intensive care, internal medicine, labor, and surgery nursing units in 3 Midwestern acute-care hospitals who completed questionnaires between August and December 2011 and 50 Nurse Managers from the units who completed questionnaires in December 2012. Cross-sectional analyses of RN emotional exhaustion linked to survey data on safety organizing and hospital incident reporting system data on adverse event rates for the year before survey administration. Cross-sectional analysis of unit-level RN turnover rates for the year following the administration of the survey linked to survey data on safety organizing. Multilevel regression analysis indicated that safety organizing was negatively associated with RN emotional exhaustion on units with higher rates of adverse events and positively associated with RN emotional exhaustion with lower rates of adverse events. Tobit regression analyses indicated that safety organizing was associated with lower unit level of turnover rates over time. Safety organizing is beneficial to caregivers in multiple ways, especially on nursing units with high levels of adverse events and over time.

    The mechanical strainer unit is connected to a flanged conduit which originates in and extends out of a suppression chamber in a nuclear reactor. The strainer includes a plurality of centrally apertured plates positioned along a common central axis and in parallel and spaced relationship. The plates have a plurality of bores radially spaced about the central axis. Spacer means such as washers are positioned between adjacent plates to maintain the plates is spaced relationship and form communicating passages of a predetermined size to the central apertures. Connecting means such as bolts or studs extend through the aligned bores to maintain the unit in assembled relationship and secure the unit to the pipe. By employing perforated plates and blocking off certain of the communicating passages, a dual straining effect can be achieved

    Full Text Available The globalization of the world economy has opened up new possibilities for cross-border labor organizing. In fact, several U.S. unions are working together with unions from Mexico, Honduras, Guatemala, the Dominican Republic, Japan, South Korea, and many European nations. For example, over the last several years, UNITE (Union of Needletrades, Industrial, and Textile Employees, the AFL-CIO, and the international garment workers trade secretariat have worked directly with maquiladora workers in Honduras and the Dominican Republic. These efforts led to the formation of several labor unions and the first contracts ever negotiated in the maquiladoras in the Dominican Republic. In addition, labor rights and solidarity organizations, like the Campaign for Labor Rights, Witness for Peace, and the US/Guatemala Labor Education Project (US/GLEP, along with many other groups, have also played key roles in the formation of maquiladora unions in Nicaragua and Guatemala.

    1999-05-01

    We addressed whether muscle quality (force per unit muscle mass) changes with age in cross-sectional and longitudinal analyses from three groups from the Baltimore Longitudinal Study of Aging: (1) Isometric arm strength studied cross-sectionally in 617 subjects with muscle mass estimated by cross-sectional area (CSA) from arm circumference and by 24-hour urinary creatinine excretion (CREAT); (2) longitudinal study for 10 to 25 years in 412 men using the same measures as the first group; and (3) isometric knee extensor strength studied cross-sectionally in 675 subjects; muscle mass estimated by CREAT, CSA from thigh circumference, and leg nonosseous fat free mass (FFM) from dual energy x-ray absorptiometry. Muscle quality declined in both arm and leg with age in cross-sectional analyses using CSA and FFM, but not CREAT. No age-associated arm muscle quality declines were observed longitudinally using CREAT or CSA. The relationship between muscle quality and age is dependent on how muscle mass is estimated and on whether subjects are studied cross-sectionally or longitudinally. In addition, CREAT may measure a muscle property not accounted for by CSA or FFM.

Neonates experienced a total of 404 painful procedures over a 24 h period (mean=4.3, SD 2.0; range 1-12); 270 tissue-damaging (mean=2.85, SD 1.1; range 1-6) and 134 non-tissue-damaging procedures (mean=1.41, SD 1.2; range 0-6). Peripheral cannula insertion (27%) and intramuscular injections (22%) were the most common painful procedures. Ventilated neonates and neonates admitted in level II neonatal units had a higher number of painful procedures than those admitted in level I units (mean 4.76 vs 2.96). Only one procedure had a pain intensity score documented; and none had been performed with any form of analgesia. Neonates in Kenya were exposed to numerous tissue-damaging and non-tissue-damaging procedures without any form of analgesia. Our findings suggest that education is needed on how to assess and manage procedural pain in neonatal units in Kenya. Published by the BMJ Publishing Group Limited.

    much past the unidimensional level. Are unidimensional structures, at least, universal? Very probably the answer to this question is yes. Although systems for counting, for example, vary widely, no culture has yet been found in which counting does not play some role or where young children fail to pass Piaget's conservation of number test (Saxe, 1988). It seems highly likely, therefore, that a mental counting line of some sort is a universal construction. The situation in the domain of narrative is quite similar. Although folktales vary widely from one culture to the next, no culture has been reported in which folktales play no role whatever or where the story line of existing folktales does not have some form of intentional component (Propp, 1922/1968). The mental story line may thus be a universal construction as well. Finally, no culture has been reported in which some form of decorative art is not present or in which no technology exists for launching a projectile along a desired trajectory. If these activities require a mental reference line of some sort, then this would be a candidate for universal conceptual attainment as well. In the present series of studies, our investigations were confined to societies that are modern, highly literate, and schooled. Thus, our interest was in demonstrating a universal progression well beyond the unidimensional level, in the sorts of structure that are crucial to life in a modern industrial culture. In fact, this was what we found in each of our studies. On our tests of central conceptual structures, children progressed through the same stages and at the same rate. By contrast, on our tests of more specific understanding, especially on those dealing with issues on which different cultures place different emphasis, we found large and significant cross-national differences. From this we conclude that, if a culture values a particular task or set of tasks and invests a great deal of effort in teaching them, it is likely that the

  7. Experiments on nonlinear cross waves

    1986-12-01

    Surface water waves are generated by a paddle-type wavemaker operating at one end of a long tank. In addition to a progressing wave field at the forcing frequency, a subharmonic cross wave is generated in the neighborhood of the wavemaker. At lower forcing amplitudes there is a Benjamin-Feir instability of the progressing wave. At large forcing amplitudes, the fundamental decays rapidly along the channel. The cross wave dominates the near field and is strongly modulated on a slow time scale. During each modulation period a soliton propagates away from the wavemaker. The near-field standing cross wave undergoes a transformation into a progressing wave in the far field.

  12. MATRIX FOR COOPERATION IN THE CROSS-BORDER AREAS

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available The crossborder areas have no constitutional competences, therefore most of the times they are not part of the decision making process in the agreements in cross-border relationships. Although the states are the ones to decide the policies and the agreements based on their own legal rules, considering the shape of the new European Union, they should more and more accept the conditionality of a regional overstate structure linked only to some geographical parts of the countries. The present paper proposes a theoretical and intuitive frame for assessing the cross-border areas based on the factors that are influencing it, starting from a listing of them, secondly grouping them in separating and uniting, then finding the significant differences. The matrix of factors can be used for conflict resolution or for development of cross-border areas as long as it shows the points that will be a potential obstacle or a source for cooperation.

  13. Cross-National Trends in Religious Service Attendance.

    Brenner, Philip S

    2016-01-01

    The nature of religious change and the future of religion have been central questions of social science since its inception. But empirical research on this question has been quite American-centric, encouraged by the conventional wisdom that the United States is an outlier of religiosity in the developed world, and, more pragmatically, by the availability of survey data. The dramatic growth in the number and reach of cross-national surveys over the past two decades has offered a corrective. These data have allowed research on religious trends in the United States, Canada, and Europe, putting American trends into comparative relief. This research synthesis reviews the past quarter century of cross-national comparative survey research on religious behavior, focusing on religious service attendance as a commonly measured behavior that is arguably more equivalent across societies and cultures than other measures of religiosity. The lack of evidence for religious revival is highlighted, noting instead declining rates of attendance in the United States and Canada, and either declining rates or low "bottomed-out" stability in Western Europe, most of Eastern Europe, and Australia and New Zealand. Finally, countries in Latin America, Africa, and Asia are discussed to the extent that research allows, before a call for future research-in these places in particular-is made in order to correct for the Western and Christian focus of much of the research on cross-national religious trends.

    For blind travelers, finding crosswalks and remaining within their borders while traversing them is a crucial part of any trip involving street crossings. While standard Orientation & Mobility (O&M) techniques allow blind travelers to safely negotiate street crossings, additional information about crosswalks and other important features at intersections would be helpful in many situations, resulting in greater safety and/or comfort during independent travel. For instance, in planning a trip a blind pedestrian may wish to be informed of the presence of all marked crossings near a desired route. We have conducted a survey of several O&M experts from the United States and Italy to determine the role that crosswalks play in travel by blind pedestrians. The results show stark differences between survey respondents from the U.S. compared with Italy: the former group emphasized the importance of following standard O&M techniques at all legal crossings (marked or unmarked), while the latter group strongly recommended crossing at marked crossings whenever possible. These contrasting opinions reflect differences in the traffic regulations of the two countries and highlight the diversity of needs that travelers in different regions may have. To address the challenges faced by blind pedestrians in negotiating street crossings, we devised a computer vision-based technique that mines existing spatial image databases for discovery of zebra crosswalks in urban settings. Our algorithm first searches for zebra crosswalks in satellite images; all candidates thus found are validated against spatially registered Google Street View images. This cascaded approach enables fast and reliable discovery and localization of zebra crosswalks in large image datasets. While fully automatic, our algorithm can be improved by a final crowdsourcing validation. To this end, we developed a Pedestrian Crossing Human Validation (PCHV) web service, which supports crowdsourcing to rule out false positives

  19. CROSS-TRADITIONAL BOUNDARIES OF URBAN PLANNING

    Directory of Open Access Journals (Sweden)

    Behnam GHASEMZADEH

    2013-06-01

    Full Text Available This research explores the cross-traditional boundaries of urban planning and design. Using the United States as an example, many urban areas have become epicenters for crime, squalor and destitution. However, many cities have reinvigorated and revitalized urban areas to make them colorful, vibrant and product to society rather than being a focal point of crime and urban blight. This is where an effective urban planner comes into play. A good urban planner and/or designer will know the principles to adhere to and steps to take to maintain or improve the conditions of an urban area through effective planning and design. There are different major parts to this subject but they blend and mold together in many different ways. The objective of this research is to identify the trends and patterns that define good urban design and planning and some examples that are not emblematic of good practice. The methodology behind this study will be mostly qualitative analysis. The scope of what will be looked at will be urban areas within the United States. The findings of this report is that urban planning design is sometimes done extremely well and with excellent results while other times it is done quite poorly despite a wealth of funding and resources to help do it right the first time. The overall conclusion of this study is that urban planning can be done extremely well but the methodology and specifics to the urban area in question matter greatly.

    The portable Contamination Analysis Unit (CAU) measures trace quantities of surface contamination in real time. The detector head of the portable contamination analysis unit has an opening with an O-ring seal, one or more vacuum valves and a small mass spectrometer. With the valve closed, the mass spectrometer is evacuated with one or more pumps. The O-ring seal is placed against a surface to be tested and the vacuum valve is opened. Data is collected from the mass spectrometer and a portable computer provides contamination analysis. The CAU can be used to decontaminate and decommission hazardous and radioactive surfaces by measuring residual hazardous surface contamination, such as tritium and trace organics. It provides surface contamination data for research and development applications as well as real-time process control feedback for industrial cleaning operations and can be used to determine the readiness of a surface to accept bonding or coatings. 1 fig

  4. Cross-Gendering the Racial Memory

    Directory of Open Access Journals (Sweden)

    Marlon B. Ross

    2006-05-01

    Full Text Available When Ernest Gaines chooses a woman as the individual subject for collective memorialization and the ideal medium of racial memory in his 1971 novel, The Autobiography of Miss Jane Pittman, he participates in a significant but overlooked genre of black masculine discourse, the composition of black authorship as historical/national authority through the voice and viewpoint of a female protagonist. This cross-gendering of the racial imaginary, introjecting a male vision of racial collectivity and history through a female’s frame of reference, though not exactly a form of cross-dressing, can be usefully analyzed as such. Erecting a feminine monument to emblematize and materialize highly abstract notions like nationhood, justice, peace, warfare, virtue, democracy, pro/creativity, and truth has a long history in many cultures across the globe. It is a long-standing practice within many patriarchal cultures, in other words, to project highly abstract masculine visions of established power onto a female form, draped in feminine attire. Whether this occurs metaphorically, as in the case of gendering the nation-state as feminine (Britannia for the United Kingdom, Columbia for the United States, St. Joan for France, etc., or through more literal iconography, such as the Statue of Liberty, the feminine form serves to purify, emblematize, and collectivize—and thus to transcendentalize—concepts of rightful dis/empowerment that are otherwise fraught with cultural-historical strife. The static nature of such imagery distances us from the contentiousness of the act of cross-gendering that occurs ideologically in the enunciation or re-erection of patriarchal power through an objectified, if celebrated, feminine icon.We can find evidence of this conventionally patriarchal kind of feminine iconography in black cultural practice.  For instance, in black nationalist discourse of the 1960s and ’70s (whether in the Black Power movement in the United States or

    Full Text Available Subject of Research. The results of lidar combined scanning unit development for locating leaks of hydrocarbons are presented The unit enables to perform high-speed scanning of the investigated space in wide and narrow angle fields. Method. Scanning in a wide angular field is produced by one-line scanning path by means of the movable aluminum mirror with a frequency of 20Hz and amplitude of 20 degrees of swing. Narrowband scanning is performed along a spiral path by the deflector. The deflection of the beam is done by rotation of the optical wedges forming part of the deflector at an angle of ±50. The control function of the scanning node is performed by a specialized software product written in C# programming language. Main Results. This scanning unit allows scanning the investigated area at a distance of 50-100 m with spatial resolution at the level of 3 cm. The positioning accuracy of the laser beam in space is 15'. The developed scanning unit gives the possibility to browse the entire investigated area for the time not more than 1 ms at a rotation frequency of each wedge from 50 to 200 Hz. The problem of unambiguous definition of the beam geographical coordinates in space is solved at the software level according to the rotation angles of the mirrors and optical wedges. Lidar system coordinates are determined by means of GPS. Practical Relevance. Development results open the possibility for increasing the spatial resolution of scanning systems of a wide range of lidars and can provide high positioning accuracy of the laser beam in space.

    In the United States, the advanced technologies have been applied to uranium enrichment as a means by which it can be assured that nuclear fuel cost will remain competitive in the future. The United States is strongly committed to the development of advanced enrichment technology, and has brought both advanced gas centrifuge (AGC) and atomic vapor laser isotope separation (AVLIS) programs to a point of significant technical refinement. The ability to deploy advanced technologies is the basis for the confidence in competitive future price. Unfortunately, the development of advanced technologies is capital intensive. The year 1985 is the key year for advanced technology development in the United States, since the decision on the primary enrichment technology for the future, AGC or AVLIS, will be made shortly. The background on the technology selection process, the highlights of AGC and AVLIS programs and the way to proceed after the process selection are described. The key objective is to maximize the sales volume and minimize the operating cost. This will help the utilities in other countries supply low cost energy on a reliable, long term basis. (Kako, I.)

    Upon pressure from the United States Congress, the US Department of Energy had to withdraw from further American participation in the ITER Engineering Design Activities after the end of its commitment to the EDA in July 1998. In the years since that time, changes have taken place in both the ITER activity and the US fusion community's position on burning plasma physics. Reflecting the interest in the United States in pursuing burning plasma physics, the DOE's Office of Science commissioned three studies as part of its examination of the option of entering the Negotiations on the Agreement on the Establishment of the International Fusion Energy Organization for the Joint Implementation of the ITER Project. These were a National Academy Review Panel Report supporting the burning plasma mission; a Fusion Energy Sciences Advisory Committee (FESAC) report confirming the role of ITER in achieving fusion power production, and The Lehman Review of the ITER project costing and project management processes (for the latter one, see ITER CTA Newsletter, no. 15, December 2002). All three studies have endorsed the US return to the ITER activities. This historical decision was announced by DOE Secretary Abraham during his remarks to employees of the Department's Princeton Plasma Physics Laboratory. The United States will be working with the other Participants in the ITER Negotiations on the Agreement and is preparing to participate in the ITA

    Hoechst is considering plans to build its first ethoxylates project in Mexico, Mark Sijthoff, head of surfactants and auxiliaries for Hoechst`s specialty chemical business unit, tells CW. The company expects to make a decision on the 30,000-m.t./year project by the end of the year. Sijthoff would not disclose the site or where ethylene oxide (EO) feed would be obtained. The plan may depend on results of the privatization of Petroleos Mexicanos (Pemex), which is the only producer of EO in Mexico. Hoechst is part of a consortium bidding on the privatization. Sources say the unit will be built at Quimica Hoechst`s Coatzacoalcos site, close to Pemex`s EO plants at Cangregera and Morelos. A planned EO expansion at Morelos will probably move ahead when the sell-off is completed. Sijthoff says that Hoechst is also looking at improving its US surfactants position, although the company has no plans to expand ethoxylates, as there is {open_quotes}plenty of capacity.{close_quotes} Hoechst started up a 150-million lbs/year plant at Clear Lake, TX last year, ending a tolling agreement with Union Carbide. In addition, Rhone-Poulenc recently started a unit at Marcus Hook, PA, and Condea Vista is doubling its ethoxylation capacity at Lake Charles, LA. Meanwhile, Hoechst is still considering construction of 30,000-m.t./year ethoxylation plant in India or China. A decision is expected later this year.

    This article reviews research on cross-cultural organizational behavior (OB). After a brief review of the history of cross-cultural OB, we review research on work motivation, or the factors that energize, direct, and sustain effort across cultures. We next consider the relationship between the individual and the organization, and review research on culture and organizational commitment, psychological contracts, justice, citizenship behavior, and person-environment fit. Thereafter, we consider how individuals manage their interdependence in organizations, and review research on culture and negotiation and disputing, teams, and leadership, followed by research on managing across borders and expatriation. The review shows that developmentally, cross-cultural research in OB is coming of age. Yet we also highlight critical challenges for future research, including moving beyond values to explain cultural differences, attending to levels of analysis issues, incorporating social and organizational context factors into cross-cultural research, taking indigenous perspectives seriously, and moving beyond intracultural comparisons to understand the dynamics of cross-cultural interfaces.

    To define the continuing education topics and methods in the area of chemistry and hematology, that if developed, would best support the cross-training needs of hospital based laboratories in the State of Georgia. A cross sectional study of hospital based laboratories in Georgia was completed using surveys sent to 181 hospital laboratory managers and administrators. Descriptive statistics were used to evaluate the survey results. Department of Medical Technology, Medical College of Georgia, Augusta GA. Laboratory managers and administrators. Not applicable. Four descriptive outcome measurements were requested from each participant: 1) demographic questions, 2) cross-training topics desired, 3) training material desired, and 4) computer literacy and equipment assessment. Sixty-six surveys were completed and returned in a usable form (36% return rate). Demographically, the respondent group is a representative sample of hospital based laboratories in the State of Georgia with 46% of the respondents from facilities of 100 hospital beds or less. Respondents desired that case study training topics be developed using paper and computer assisted instruction mediums. Additionally, respondents desired that Professional Acknowledgement for Continuing Education (P.A.C.E.) be associated with the training material. They were willing to pay for this administrative service. This cross sectional study assessed the cross-training needs of hospital based laboratories in Georgia. Findings will allow educators to focus and develop continuing education packages that best meet the needs of the laboratorian workforce.

    to analyze waste management in urgency and emergency non-hospital health care service units. Epidemiological cross-sectional study undertaken at three Non-Hospital Emergency Units. The data were collected using systematic observation, registered daily in a spreadsheet and checklist, and analyzed through descriptive statistics. the generation of waste varied from 0.087 to 0.138 kg per patient per day. Waste management showed inadequacies in all stages, especially in the separation stage. Infectious waste was found together with common waste, preventing recycling, and piercing and cutting objects were mixed with waste from different groups, increasing the risk of occupational accidents. the study reveals the lack of an institutional waste management policy, as demonstrated by the failure of operational stages, involving problems related to management, physical structure, material and human resources at the units. This is relevant for health care units, considering the quality of patient care and its interface with sustainability.

    CrossFit is a growing fitness trend in the United States; however, little systematic research has addressed specific motivational principles within this unique exercise environment. The purpose of the study was to explore the influence of gender and membership time on perceptions of motivational climate and goals within the CrossFit environment. Specifically, people may set goals related to self-improvement (i.e., mastery) or focus on their performance in comparison to others (i.e., performance). Motivational climate refers to an individual's perception of being encouraged to focus on either mastery or performance goals from CrossFit trainers. A total of 144 members (88 females; 56 males) completed questionnaires to assess participants' perceptions of CrossFit goal structures and perceptions of the motivational climate encouraged by the trainer within their CrossFit box. Results indicated a significant main effect for gender on preferred goals (p ≤ 0.05), with males reporting higher levels of performance approach goals and females reporting higher levels of master avoidance goals. Participants who reported shorter membership times were found to have significantly higher mastery-related goals than individuals who reported longer membership times (p ≤ 0.05). The results from the study suggest that practitioners should consider how perceptions of the motivational climate and goals in group-based exercise settings such as CrossFit may vary based on demographic variables, and that these differences may impact how to most effectively motivate, encourage, and instruct group members, particularly with regard to helping members set goals that most effectively address their approach to the CrossFit regimen.

    One of the most justified and pressing demands that society makes of the State, requiring a fast, forceful and effective response, is that it guarantees the safety of people and their assets when a disaster seriously endangers them. At the proposal of the President of the Government, the Cabinet of Ministers, in its meeting held on October 7, 2005, agreed to create the Military Emergency Unit, known since the as the UME. Its mission is to intervene anywhere in the national territory when the President of the Government, or the Minister to whom he delegates, so decides in order to assure the safety and welfare of citizens in cases of serious risk, disaster, catastrophe or any other public need. The UME is organically incorporated into the Ministry of Defense and its actions may be supported with all the available human and material needs of the Armed Forces. Availability and effectiveness, with calmness and humility, have characterized the early actions of the Military Emergency Unit and are the guidelines for future action. The first steps of this military unit have focused on a clear goal: collaboration and participation in situations whose seriousness requires the coordination of different forces in order to immediately respond to them. The UME is the States tool to join forces and, with other administration and institutions, help to rapidly and effectively deal with emergencies. It has taken its first step and achieved the capacity specified in the UME Operations Order for 2007. The 150 men and women per battalion, plus the 80 in the Gando detachment, are on active duty and have sufficient material means to deploy, if necessary and when requested by the regions, town councils an other administrative bodies, to help in the extinction of forest fires.
