A novel equivalent definition of Caputo fractional derivative without singular kernel and superconvergent analysis

NASA Astrophysics Data System (ADS)

Liu, Zhengguang; Li, Xiaoli

2018-05-01

In this article, we present a new second-order finite difference discrete scheme for a fractal mobile/immobile transport model based on equivalent transformative Caputo formulation. The new transformative formulation takes the singular kernel away to make the integral calculation more efficient. Furthermore, this definition is also effective where α is a positive integer. Besides, the T-Caputo derivative also helps us to increase the convergence rate of the discretization of the α-order(0 < α < 1) Caputo derivative from O(τ2-α) to O(τ3-α), where τ is the time step. For numerical analysis, a Crank-Nicolson finite difference scheme to solve the fractal mobile/immobile transport model is introduced and analyzed. The unconditional stability and a priori estimates of the scheme are given rigorously. Moreover, the applicability and accuracy of the scheme are demonstrated by numerical experiments to support our theoretical analysis.

Convergence Analysis of Triangular MAC Schemes for Two Dimensional Stokes Equations

Wang, Ming; Zhong, Lin

2015-01-01

In this paper, we consider the use of H(div) elements in the velocity–pressure formulation to discretize Stokes equations in two dimensions. We address the error estimate of the element pair RT0–P0, which is known to be suboptimal, and render the error estimate optimal by the symmetry of the grids and by the superconvergence result of Lagrange inter-polant. By enlarging RT0 such that it becomes a modified BDM-type element, we develop a new discretization BDM1b–P0. We, therefore, generalize the classical MAC scheme on rectangular grids to triangular grids and retain all the desirable properties of the MAC scheme: exact divergence-free, solver-friendly, and local conservation of physical quantities. Further, we prove that the proposed discretization BDM1b–P0 achieves the optimal convergence rate for both velocity and pressure on general quasi-uniform grids, and one and half order convergence rate for the vorticity and a recovered pressure. We demonstrate the validity of theories developed here by numerical experiments. PMID:26041948

EXPLICIT LEAST-DEGREE BOUNDARY FILTERS FOR DISCONTINUOUS GALERKIN.

Nguyen, Dang-Manh; Peters, Jörg

Convolving the output of Discontinuous Galerkin (DG) computations using spline filters can improve both smoothness and accuracy of the output. At domain boundaries, these filters have to be one-sided for non-periodic boundary conditions. Recently, position-dependent smoothness-increasing accuracy-preserving (PSIAC) filters were shown to be a superset of the well-known one-sided RLKV and SRV filters. Since PSIAC filters can be formulated symbolically, PSIAC filtering amounts to forming linear products with local DG output and so offers a more stable and efficient implementation. The paper introduces a new class of PSIAC filters NP 0 that have small support and are piecewise constant. Extensive numerical experiments for the canonical hyperbolic test equation show NP 0 filters outperform the more complex known boundary filters. NP 0 filters typically reduce the L ∞ error in the boundary region below that of the interior where optimally superconvergent symmetric filters of the same support are applied. NP 0 filtering can be implemented as forming linear combinations of the data with short rational weights. Exact derivatives of the convolved output are easy to compute.

Generalized Fourier analyses of the advection-diffusion equation - Part I: one-dimensional domains

Christon, Mark A.; Martinez, Mario J.; Voth, Thomas E.

2004-07-01

This paper presents a detailed multi-methods comparison of the spatial errors associated with finite difference, finite element and finite volume semi-discretizations of the scalar advection-diffusion equation. The errors are reported in terms of non-dimensional phase and group speed, discrete diffusivity, artificial diffusivity, and grid-induced anisotropy. It is demonstrated that Fourier analysis provides an automatic process for separating the discrete advective operator into its symmetric and skew-symmetric components and characterizing the spectral behaviour of each operator. For each of the numerical methods considered, asymptotic truncation error and resolution estimates are presented for the limiting cases of pure advection and pure diffusion. It is demonstrated that streamline upwind Petrov-Galerkin and its control-volume finite element analogue, the streamline upwind control-volume method, produce both an artificial diffusivity and a concomitant phase speed adjustment in addition to the usual semi-discrete artifacts observed in the phase speed, group speed and diffusivity. The Galerkin finite element method and its streamline upwind derivatives are shown to exhibit super-convergent behaviour in terms of phase and group speed when a consistent mass matrix is used in the formulation. In contrast, the CVFEM method and its streamline upwind derivatives yield strictly second-order behaviour. In Part II of this paper, we consider two-dimensional semi-discretizations of the advection-diffusion equation and also assess the affects of grid-induced anisotropy observed in the non-dimensional phase speed, and the discrete and artificial diffusivities. Although this work can only be considered a first step in a comprehensive multi-methods analysis and comparison, it serves to identify some of the relative strengths and weaknesses of multiple numerical methods in a common analysis framework.

Critical to the scalability of parallel adaptive simulations are parallel control functions including load balancing, reduced inter-process communication and optimal data decomposition. In distributed meshes, many mesh-based applications frequently access neighborhood information for computational purposes which must be transmitted efficiently to avoid parallel performance degradation when the neighbors are on different processors. This article presents a parallel algorithm of creating and deleting data copies, referred to as ghost copies, which localize neighborhood data for computation purposes while minimizing inter-process communication. The key characteristics of the algorithm are: (1) It can create ghost copies of any permissible topological order in amore » 1D, 2D or 3D mesh based on selected adjacencies. (2) It exploits neighborhood communication patterns during the ghost creation process thus eliminating all-to-all communication. (3) For applications that need neighbors of neighbors, the algorithm can create n number of ghost layers up to a point where the whole partitioned mesh can be ghosted. Strong and weak scaling results are presented for the IBM BG/P and Cray XE6 architectures up to a core count of 32,768 processors. The algorithm also leads to scalable results when used in a parallel super-convergent patch recovery error estimator, an application that frequently accesses neighborhood data to carry out computation.« less

Stress Recovery and Error Estimation for 3-D Shell Structures

NASA Technical Reports Server (NTRS)

Riggs, H. R.

2000-01-01

The C1-continuous stress fields obtained from finite element analyses are in general lower- order accurate than are the corresponding displacement fields. Much effort has focussed on increasing their accuracy and/or their continuity, both for improved stress prediction and especially error estimation. A previous project developed a penalized, discrete least squares variational procedure that increases the accuracy and continuity of the stress field. The variational problem is solved by a post-processing, 'finite-element-type' analysis to recover a smooth, more accurate, C1-continuous stress field given the 'raw' finite element stresses. This analysis has been named the SEA/PDLS. The recovered stress field can be used in a posteriori error estimators, such as the Zienkiewicz-Zhu error estimator or equilibrium error estimators. The procedure was well-developed for the two-dimensional (plane) case involving low-order finite elements. It has been demonstrated that, if optimal finite element stresses are used for the post-processing, the recovered stress field is globally superconvergent. Extension of this work to three dimensional solids is straightforward. Attachment: Stress recovery and error estimation for shell structure (abstract only).

The impact of groundwater velocity fields on streamlines in an aquifer system with a discontinuous aquitard (Inner Mongolia, China)

2018-04-01

Many numerical methods that simulate groundwater flow, particularly the continuous Galerkin finite element method, do not produce velocity information directly. Many algorithms have been proposed to improve the accuracy of velocity fields computed from hydraulic potentials. The differences in the streamlines generated from velocity fields obtained using different algorithms are presented in this report. The superconvergence method employed by FEFLOW, a popular commercial code, and some dual-mesh methods proposed in recent years are selected for comparison. The applications to depict hydrogeologic conditions using streamlines are used, and errors in streamlines are shown to lead to notable errors in boundary conditions, the locations of material interfaces, fluxes and conductivities. Furthermore, the effects of the procedures used in these two types of methods, including velocity integration and local conservation, are analyzed. The method of interpolating velocities across edges using fluxes is shown to be able to eliminate errors associated with refraction points that are not located along material interfaces and streamline ends at no-flow boundaries. Local conservation is shown to be a crucial property of velocity fields and can result in more accurate streamline densities. A case study involving both three-dimensional and two-dimensional cross-sectional models of a coal mine in Inner Mongolia, China, are used to support the conclusions presented.

Accurate interlaminar stress recovery from finite element analysis

NASA Technical Reports Server (NTRS)

Tessler, Alexander; Riggs, H. Ronald

1994-01-01

The accuracy and robustness of a two-dimensional smoothing methodology is examined for the problem of recovering accurate interlaminar shear stress distributions in laminated composite and sandwich plates. The smoothing methodology is based on a variational formulation which combines discrete least-squares and penalty-constraint functionals in a single variational form. The smoothing analysis utilizes optimal strains computed at discrete locations in a finite element analysis. These discrete strain data are smoothed with a smoothing element discretization, producing superior accuracy strains and their first gradients. The approach enables the resulting smooth strain field to be practically C1-continuous throughout the domain of smoothing, exhibiting superconvergent properties of the smoothed quantity. The continuous strain gradients are also obtained directly from the solution. The recovered strain gradients are subsequently employed in the integration o equilibrium equations to obtain accurate interlaminar shear stresses. The problem is a simply-supported rectangular plate under a doubly sinusoidal load. The problem has an exact analytic solution which serves as a measure of goodness of the recovered interlaminar shear stresses. The method has the versatility of being applicable to the analysis of rather general and complex structures built of distinct components and materials, such as found in aircraft design. For these types of structures, the smoothing is achieved with 'patches', each patch covering the domain in which the smoothed quantity is physically continuous.

Elastic-plastic models for multi-site damage

Actis, Ricardo L.; Szabo, Barna A.

1994-01-01

This paper presents recent developments in advanced analysis methods for the computation of stress site damage. The method of solution is based on the p-version of the finite element method. Its implementation was designed to permit extraction of linear stress intensity factors using a superconvergent extraction method (known as the contour integral method) and evaluation of the J-integral following an elastic-plastic analysis. Coarse meshes are adequate for obtaining accurate results supported by p-convergence data. The elastic-plastic analysis is based on the deformation theory of plasticity and the von Mises yield criterion. The model problem consists of an aluminum plate with six equally spaced holes and a crack emanating from each hole. The cracks are of different sizes. The panel is subjected to a remote tensile load. Experimental results are available for the panel. The plasticity analysis provided the same limit load as the experimentally determined load. The results of elastic-plastic analysis were compared with the results of linear elastic analysis in an effort to evaluate how plastic zone sizes influence the crack growth rates. The onset of net-section yielding was determined also. The results show that crack growth rate is accelerated by the presence of adjacent damage, and the critical crack size is shorter when the effects of plasticity are taken into consideration. This work also addresses the effects of alternative stress-strain laws: The elastic-ideally-plastic material model is compared against the Ramberg-Osgood model.

Improvements on a non-invasive, parameter-free approach to inverse form finding

Our objective is to determine the optimal undeformed workpiece geometry (material configuration) within forming processes when the prescribed deformed geometry (spatial configuration) is given. For solving the resulting shape optimization problem—also denoted as inverse form finding—we use a novel parameter-free approach, which relocates in each iteration the material nodal positions as design variables. The spatial nodal positions computed by an elasto-plastic finite element (FE) forming simulation are compared with their prescribed values. The objective function expresses a least-squares summation of the differences between the computed and the prescribed nodal positions. Here, a recently developed shape optimization approach (Landkammer and Steinmann in Comput Mech 57(2):169-191, 2016) is investigated with a view to enhance its stability and efficiency. Motivated by nonlinear optimization theory a detailed justification of the algorithm is given. Furthermore, a classification according to shape changing design, fixed and controlled nodal coordinates is introduced. Two examples with large elasto-plastic strains demonstrate that using a superconvergent patch recovery technique instead of a least-squares (L2 )-smoothing improves the efficiency. Updating the interior discretization nodes by solving a fictitious elastic problem also reduces the number of required FE iterations and avoids severe mesh distortions. Furthermore, the impact of the inclusion of the second deformation gradient in the Hessian of the Quasi-Newton approach is analyzed. Inverse form finding is a crucial issue in metal forming applications. As a special feature, the approach is designed to be coupled in a non-invasive fashion to arbitrary FE software.

Damped gyroscopic effects and axial-flexural-torsional coupling using spinning finite elements for wind-turbine blades characterization

NASA Astrophysics Data System (ADS)

Velazquez, Antonio; Swartz, R. Andrew

2013-04-01

Renewable energy sources like wind are important technologies, useful to alleviate for the current fossil-fuel crisis. Capturing wind energy in a more efficient way has resulted in the emergence of more sophisticated designs of wind turbines, particularly Horizontal-Axis Wind Turbines (HAWTs). To promote efficiency, traditional finite element methods have been widely used to characterize the aerodynamics of these types of multi-body systems and improve their design. Given their aeroelastic behavior, tapered-swept blades offer the potential to optimize energy capture and decrease fatigue loads. Nevertheless, modeling special complex geometries requires huge computational efforts necessitating tradeoffs between faster computation times at lower cost, and reliability and numerical accuracy. Indeed, the computational cost and the numerical effort invested, using traditional FE methods, to reproduce dependable aerodynamics of these complex-shape beams are sometimes prohibitive. A condensed Spinning Finite Element (SFE) method scheme is presented in this study aimed to alleviate this issue by means of modeling wind-turbine rotor blades properly with tapered-swept cross-section variations of arbitrary order via Lagrangian equations. Axial-flexural-torsional coupling is carried out on axial deformation, torsion, in-plane bending and out-of-plane bending using super-convergent elements. In this study, special attention is paid for the case of damped yaw effects, expressed within the described skew-symmetric damped gyroscopic matrix. Dynamics of the model are analyzed by achieving modal analysis with complex-number eigen-frequencies. By means of mass, damped gyroscopic, and stiffness (axial-flexural-torsional coupling) matrix condensation (order reduction), numerical analysis is carried out for several prototypes with different tapered, swept, and curved variation intensities, and for a practical range of spinning velocities at different rotation angles. A convergence study for the resulting natural frequencies is performed to evaluate the dynamic collateral effects of tapered-swept blade profiles in spinning motion using this new model. Stability analysis in boundary conditions of the postulated model is achieved to test the convergence and integrity of the mathematical model. The proposed framework presumes to be particularly suitable to characterize models with complex-shape cross-sections at low computation cost.

An adaptive discontinuous Galerkin solver for aerodynamic flows

NASA Astrophysics Data System (ADS)

Burgess, Nicholas K.

This work considers the accuracy, efficiency, and robustness of an unstructured high-order accurate discontinuous Galerkin (DG) solver for computational fluid dynamics (CFD). Recently, there has been a drive to reduce the discretization error of CFD simulations using high-order methods on unstructured grids. However, high-order methods are often criticized for lacking robustness and having high computational cost. The goal of this work is to investigate methods that enhance the robustness of high-order discontinuous Galerkin (DG) methods on unstructured meshes, while maintaining low computational cost and high accuracy of the numerical solutions. This work investigates robustness enhancement of high-order methods by examining effective non-linear solvers, shock capturing methods, turbulence model discretizations and adaptive refinement techniques. The goal is to develop an all encompassing solver that can simulate a large range of physical phenomena, where all aspects of the solver work together to achieve a robust, efficient and accurate solution strategy. The components and framework for a robust high-order accurate solver that is capable of solving viscous, Reynolds Averaged Navier-Stokes (RANS) and shocked flows is presented. In particular, this work discusses robust discretizations of the turbulence model equation used to close the RANS equations, as well as stable shock capturing strategies that are applicable across a wide range of discretization orders and applicable to very strong shock waves. Furthermore, refinement techniques are considered as both efficiency and robustness enhancement strategies. Additionally, efficient non-linear solvers based on multigrid and Krylov subspace methods are presented. The accuracy, efficiency, and robustness of the solver is demonstrated using a variety of challenging aerodynamic test problems, which include turbulent high-lift and viscous hypersonic flows. Adaptive mesh refinement was found to play a critical role in obtaining a robust and efficient high-order accurate flow solver. A goal-oriented error estimation technique has been developed to estimate the discretization error of simulation outputs. For high-order discretizations, it is shown that functional output error super-convergence can be obtained, provided the discretization satisfies a property known as dual consistency. The dual consistency of the DG methods developed in this work is shown via mathematical analysis and numerical experimentation. Goal-oriented error estimation is also used to drive an hp-adaptive mesh refinement strategy, where a combination of mesh or h-refinement, and order or p-enrichment, is employed based on the smoothness of the solution. The results demonstrate that the combination of goal-oriented error estimation and hp-adaptation yield superior accuracy, as well as enhanced robustness and efficiency for a variety of aerodynamic flows including flows with strong shock waves. This work demonstrates that DG discretizations can be the basis of an accurate, efficient, and robust CFD solver. Furthermore, enhancing the robustness of DG methods does not adversely impact the accuracy or efficiency of the solver for challenging and complex flow problems. In particular, when considering the computation of shocked flows, this work demonstrates that the available shock capturing techniques are sufficiently accurate and robust, particularly when used in conjunction with adaptive mesh refinement . This work also demonstrates that robust solutions of the Reynolds Averaged Navier-Stokes (RANS) and turbulence model equations can be obtained for complex and challenging aerodynamic flows. In this context, the most robust strategy was determined to be a low-order turbulence model discretization coupled to a high-order discretization of the RANS equations. Although RANS solutions using high-order accurate discretizations of the turbulence model were obtained, the behavior of current-day RANS turbulence models discretized to high-order was found to be problematic, leading to solver robustness issues. This suggests that future work is warranted in the area of turbulence model formulation for use with high-order discretizations. Alternately, the use of Large-Eddy Simulation (LES) subgrid scale models with high-order DG methods offers the potential to leverage the high accuracy of these methods for very high fidelity turbulent simulations. This thesis has developed the algorithmic improvements that will lay the foundation for the development of a three-dimensional high-order flow solution strategy that can be used as the basis for future LES simulations.

Traces of ternary relations

NASA Astrophysics Data System (ADS)

Zedam, Lemnaouar; Barkat, Omar; De Baets, Bernard

2018-05-01

In this paper, we generalize the notion of traces of a binary relation to the setting of ternary relations. With a given ternary relation, we associate three binary relations: its left, middle and right trace. As in the binary case, these traces facilitate the study and characterization of properties of a ternary relation. Interestingly, the traces themselves turn out to be the greatest solutions of relational inequalities associated with newly introduced compositions of a ternary relation with a binary relation (and vice versa).

Deni Akbar, Mohammad; Mizoguchi, Yoshihiro; Adiwijaya

2018-03-01

In this paper, we propose a design of fuzzy relational database to deal with a conditional probability relation using fuzzy relational calculus. In the previous, there are several researches about equivalence class in fuzzy database using similarity or approximate relation. It is an interesting topic to investigate the fuzzy dependency using equivalence classes. Our goal is to introduce a formulation of a fuzzy relational database model using the relational calculus on the category of fuzzy relations. We also introduce general formulas of the relational calculus for the notion of database operations such as ’projection’, ’selection’, ’injection’ and ’natural join’. Using the fuzzy relational calculus and conditional probabilities, we introduce notions of equivalence class, redundant, and dependency in the theory fuzzy relational database.

Spatial Relation is one of the important components of Geographical Information Science and Spatial Database. There have been lots of researches on Spatial Relation and many different spatial relations have been proposed. The relationships among these spatial relations such as hierarchy and so on are complex and this brings some difficulties to the applications and teaching of these spatial relations. This paper summaries some common spatial relations, extracts the topic types, association types, resource types of these spatial relations using the technology of Topic Maps, and builds many different relationships among these spatial relations. Finally, this paper utilizes Java and Ontopia to build a topic map among these common spatial relations, forms a complex knowledge network of spatial relations, and realizes the effective management and retrieval of spatial relations.

Emotional adjustment and distressed interpersonal relations among low-income African American mothers: moderating effects of demanding kin relations.

PubMed

Taylor, Ronald D; Budescu, Mia

2013-01-01

Association of mothers' emotional adjustment and negative kin relations with distressed interpersonal relations was examined. Among 115 low-income African American mothers, relationship of depressive symptoms, self-esteem, and demanding kin relations with psychological control and stressful interpersonal relations was assessed. Depressive symptoms and demanding kin relations were positively associated with mothers' use of psychological control in parenting. Interaction of self-esteem with demanding kin relations revealed that self-esteem was negatively associated with psychological control for mothers with high-demanding kin relations but not for mothers with low-demanding kin relations. Mothers' depressive symptoms and demanding kin relations were positively associated with their stressful interpersonal relations. Findings were discussed in terms of the need for research on the beneficial and detrimental aspects of families' social network.

Relations between parental psychological control and childhood relational aggression: reciprocal in nature?

PubMed

Kuppens, Sofie; Grietens, Hans; Onghena, Patrick; Michiels, Daisy

2009-01-01

Using a cross-lagged panel design, this study examined the directionality of relations between parental psychological control and child relational aggression. Data were collected from a proportionally stratified sample of 600 Flemish 8- to 10-year-old children at 3 measurement points with 1-year intervals. Reciprocal effects were evident in mother-child dyads. Maternal psychological control was positively related to child relational aggression 1 year later, and child relational aggression was positively related to maternal psychological control 1 year later. The father-child dyads were best represented by unidirectional parent effects. Paternal psychological control was positively related to child relational aggression 1 year later. Surprisingly, these effects emerged only for relational aggression as indexed by mother and father reports and not for relational aggression as indexed by teacher and peer measures.

2013-01-01

Behavioral studies suggest that humans evolve the capacity to cope with anxiety induced by the awareness of death's inevitability. However, the neurocognitive processes that underlie online death-related thoughts remain unclear. Our recent functional MRI study found that the processing of linguistic cues related to death was characterized by decreased neural activity in human insular cortex. The current study further investigated the time course of neural processing of death-related linguistic cues. We recorded event-related potentials (ERP) to death-related, life-related, negative-valence, and neutral-valence words in a modified Stroop task that required color naming of words. We found that the amplitude of an early frontal/central negativity at 84-120 ms (N1) decreased to death-related words but increased to life-related words relative to neutral-valence words. The N1 effect associated with death-related and life-related words was correlated respectively with individuals' pessimistic and optimistic attitudes toward life. Death-related words also increased the amplitude of a frontal/central positivity at 124-300 ms (P2) and of a frontal/central positivity at 300-500 ms (P3). However, the P2 and P3 modulations were observed for both death-related and negative-valence words but not for life-related words. The ERP results suggest an early inverse coding of linguistic cues related to life and death, which is followed by negative emotional responses to death-related information.

Most previous studies investigating relational reasoning have used visuo-spatial materials. This fMRI study aimed to determine how relational complexity affects brain activity during inductive reasoning, using numerical materials. Three numerical relational levels of the number series completion task were adopted for use: 0-relational (e.g., "23 23 23"), 1-relational ("32 30 28") and 2-relational ("12 13 15") problems. The fMRI results revealed that the bilateral dorsolateral prefrontal cortex (DLPFC) showed enhanced activity associated with relational complexity. Bilateral inferior parietal lobule (IPL) activity was greater during the 1- and 2-relational level problems than during the 0-relational level problems. In addition, the left fronto-polar cortex (FPC) showed selective activity during the 2-relational level problems. The bilateral DLPFC may be involved in the process of hypothesis generation, whereas the bilateral IPL may be sensitive to calculation demands. Moreover, the sensitivity of the left FPC to the multiple relational problems may be related to the integration of numerical relations. The present study extends our knowledge of the prefrontal activity pattern underlying numerical relational processing. Copyright © 2014 Elsevier B.V. All rights reserved.

Behavioral studies suggest that humans evolve the capacity to cope with anxiety induced by the awareness of death’s inevitability. However, the neurocognitive processes that underlie online death-related thoughts remain unclear. Our recent functional MRI study found that the processing of linguistic cues related to death was characterized by decreased neural activity in human insular cortex. The current study further investigated the time course of neural processing of death-related linguistic cues. We recorded event-related potentials (ERP) to death-related, life-related, negative-valence, and neutral-valence words in a modified Stroop task that required color naming of words. We found that the amplitude of an early frontal/central negativity at 84–120 ms (N1) decreased to death-related words but increased to life-related words relative to neutral-valence words. The N1 effect associated with death-related and life-related words was correlated respectively with individuals’ pessimistic and optimistic attitudes toward life. Death-related words also increased the amplitude of a frontal/central positivity at 124–300 ms (P2) and of a frontal/central positivity at 300–500 ms (P3). However, the P2 and P3 modulations were observed for both death-related and negative-valence words but not for life-related words. The ERP results suggest an early inverse coding of linguistic cues related to life and death, which is followed by negative emotional responses to death-related information. PMID:23840787

Empathy-related responding and prosocial behaviour.

PubMed

Eisenberg, Nancy

2007-01-01

In this paper I differentiate among empathy, sympathy and personal distress and discuss the central role of empathy-related responding in positive (including moral) development. Empathy-related responding, especially sympathy, is likely an important source of prosocial, other-oriented motivation. In fact, empathy-related responding, especially sympathy, has been associated with prosocial behaviour (voluntary behaviour intended to benefit another, e.g. helping, sharing); this relation has been obtained for both specific instances of empathy-related responding and for dispositional sympathy. In addition, sympathy (or sometimes empathy) has been linked to relatively high levels of moral reasoning and social competence, and to low levels of aggression and antisocial behaviour. In my talk, I will review research on the relation of empathy-related responding to prosocial behaviour, the consistency of costly prosocial behaviour over time and the possible role of sympathy in its consistency, and the relation of empathy-related responding to moral reasoning, antisocial behaviour and social competence. Examples of research, including longitudinal research in our laboratory, are provided to illustrate these relations. Because of its close relations to social and prosocial responding, an understanding of empathy-related responding contributes to efforts to promote children's moral development.

Cross-Domain Analogies as Relating Derived Relations among Two Separate Relational Networks

PubMed Central

Ruiz, Francisco J; Luciano, Carmen

2011-01-01

Contemporary behavior analytic research is making headway in analyzing analogy as the establishment of a relation of coordination among common types of trained or derived relations. Previous studies have been focused on within-domain analogy. The current study expands previous research by analyzing cross-domain analogy as relating relations among separate relational networks and by correlating participants' performance with a standard measure of analogical reasoning. In two experiments, adult participants first completed general intelligence and analogical reasoning tests. Subsequently, they were exposed to a computerized conditional discrimination training procedure designed to create two relational networks, each consisting of two 3-member equivalence classes. The critical test was a two-part analogical test in which participants had to relate combinatorial relations of coordination and distinction between the two relational networks. In Experiment 1, combinatorial relations for each network were individually tested prior to analogical testing, but in Experiment 2 they were not. Across both experiments, 65% of participants passed the analogical test on the first attempt. Moreover, results from the training procedure were strongly correlated with the standard measure of analogical reasoning. PMID:21547072

First studies revealed overgeneral autobiographical memories in anorexia nervosa (AN) patients. The aim of the present study was to investigate frequency, generalization and valence of autobiographical memories in AN patients in response to eating disorder-related cue words. Autobiographical memory was examined in 21 AN patients and 21 healthy controls (HC) using a modified version of the Autobiographical Memory Test, incorporating body-related, food-related, perfectionism-related, depression-related and neutral cues. Anorexia nervosa patients recalled fewer and more general autobiographical memories compared with HC. For eating disorder-related cues as against neutral ones, AN patients compared with HC showed fewer memories for food-related and body-related cues, an elevated overgeneralization for food-related cues, while the valence of the retrieved memories was more negative in response to body-related cues. This study detects disorder-related autobiographical memory alterations in AN, which are intensified in response to symptom-related cues. The findings are discussed with regard to their maladaptive function in emotion regulation. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.

Objective The purpose of this study was to evaluate the efficacy of personalized normative feedback (PNF) on college student alcohol-related risky sexual behavior (RSB). Method In a randomized controlled trial, 480 (57.6% female) sexually-active college students were stratified by gender and level of drinking and randomly assigned to an alcohol only intervention, an alcohol-related RSB only intervention, a combined alcohol and alcohol-related RSB intervention, or control. All assessment and intervention procedures were web-based. Results Results indicated a significant reduction in drinking outcomes for the alcohol only and the combined alcohol and alcohol-related RSB interventions relative to control. Findings further demonstrated a significant reduction in alcohol-related RSB outcomes for the alcohol-related RSB only and the combined alcohol and alcohol-related RSB interventions relative to control. There were no significant intervention effects on alcohol-related negative consequences. These findings demonstrate that the combined alcohol and alcohol-related RSB intervention was the only intervention successful at reducing both drinking and alcohol-related RSB outcomes relative to control. There were no significant differences when comparing the combined alcohol and alcohol-related RSB intervention to the alcohol only intervention or the alcohol-related RSB only intervention. Finally, results suggested that the intervention effects on high-risk behaviors were mediated by reductions in descriptive normative perceptions. Conclusions These findings demonstrate that PNF specific to drinking in sexual situations was needed to reduce alcohol-related RSB. Furthermore, this study highlights the potential utility of a brief intervention that can be delivered via the Internet to reduce high-risk drinking and alcohol-related RSB among college students.

New Mexico (NM) has the highest rate of non-firearm-related homicide in the USA and ranks 20th in firearm-related homicides. Because non-firearm-related homicides are inadequately described in the literature, characterisation of non-firearm-related homicide victims will enhance efforts to reduce homicides. Homicide victims were identified through the Office of the Medical Investigator. Age-specific and age-adjusted homicide death rates were calculated for 2001-3 by sex and race/ethnicity, and associations between covariates and non-firearm-related homicide were measured. Non-firearm-related homicides comprised 33% of US homicide victims, 47% of NM homicide victims, and 74% of NM American Indian (AI) homicide victims. Of 212 NM non-firearm-related homicide victims, 37% had been beaten, 32% had been stabbed, and 12% had been strangled. Females comprised 30% of non-firearm-related homicide victims and 18% of firearm-related homicide victims. A blood alcohol concentration (BAC) >or=0.08 mg/dl was detected among 43% of non-firearm-related (61% of AI) and 33% of firearm-related (50% of AI) homicide victims. Non-firearm-related homicide rates were highest among AI men aged 25-34 years (31/100,000). Non-firearm-related homicide victims were more likely than firearm-related victims to be AI (adjusted odds ratio (AOR) 4.20; 95% CI 2.16 to 8.16) and female (AOR 2.05; 95% CI 1.27 to 3.31), and to have had a BAC >or=0.08 mg/dl (AOR 1.65; 95% CI 1.08 to 2.52). Homicide-prevention efforts among AIs in NM should focus on non-firearm-related homicides. The association between excessive drinking and non-firearm-related homicide should be further characterised. Continued surveillance for non-firearm-related homicides will assist these efforts.

Correlates of sex-related differences in logical reasoning

NASA Astrophysics Data System (ADS)

Ehindero, O. J.

The study utilized a post-test-only, no-control experimental design to investigate the influence of sex-related contextual nature of tasks and perceived difficulty of these tasks on logical reasoning among 70 randomly selected high schools pupils (35 boys and 35 girls) in Nigeria. Three categories of tasks were used-those whose context were male related, those whose context were female related, and those that were relatively content-free. Results of the study show that males scored higher than females on male-related tasks and females scored higher on female-related tasks. No significant difference, however, was observed on the relatively content-free tasks. The need to design problems and tasks that are relatively nonsex-related is discussed.Received: 19 March 1982;

Maximum Relative Entropy of Coherence: An Operational Coherence Measure.

PubMed

Bu, Kaifeng; Singh, Uttam; Fei, Shao-Ming; Pati, Arun Kumar; Wu, Junde

2017-10-13

The operational characterization of quantum coherence is the cornerstone in the development of the resource theory of coherence. We introduce a new coherence quantifier based on maximum relative entropy. We prove that the maximum relative entropy of coherence is directly related to the maximum overlap with maximally coherent states under a particular class of operations, which provides an operational interpretation of the maximum relative entropy of coherence. Moreover, we show that, for any coherent state, there are examples of subchannel discrimination problems such that this coherent state allows for a higher probability of successfully discriminating subchannels than that of all incoherent states. This advantage of coherent states in subchannel discrimination can be exactly characterized by the maximum relative entropy of coherence. By introducing a suitable smooth maximum relative entropy of coherence, we prove that the smooth maximum relative entropy of coherence provides a lower bound of one-shot coherence cost, and the maximum relative entropy of coherence is equivalent to the relative entropy of coherence in the asymptotic limit. Similar to the maximum relative entropy of coherence, the minimum relative entropy of coherence has also been investigated. We show that the minimum relative entropy of coherence provides an upper bound of one-shot coherence distillation, and in the asymptotic limit the minimum relative entropy of coherence is equivalent to the relative entropy of coherence.

In this longitudinal two-wave study, bidirectional relations between work-related stress and sleep quality were examined. Moreover, it was investigated whether perseverative cognition is a potential underlying mechanism in this association, related to both work-related stress and sleep quality. A randomly selected sample of Dutch employees received an online survey in 2012 and 2013. Of all invited employees, 877 participated in both waves. Structural equation modeling was performed to analyze the data. We found evidence for reversed relations between work-related stress and sleep quality. Specifically, when controlling for perseverative cognition, work-related stress was not directly related to subsequent sleep quality, but low sleep quality was associated with an increase in work-related stress over time. Moreover, negative bidirectional associations over time were found between perseverative cognition and sleep quality, and positive bidirectional associations were found between work-related stress and perseverative cognition. Lastly, a mediation analysis showed that perseverative cognition fully mediated the relationship between work-related stress and sleep quality. The study findings suggest that perseverative cognition could be an important underlying mechanism in the association between work-related stress and sleep quality. The bidirectionality of the studied relationships could be an indication of a vicious cycle, in which work-related stress, perseverative cognition, and sleep quality mutually influence each other over time.

This research examines the relative importance that cancer-related and non-cancer illness factors play in generating general health worries and/or cancer-related worries. The analysis also examines how these in turn impact anxiety and depression among older adult, long-term cancer survivors. Data from a longitudinal study of 245 older-adult (age 60+ years), long-term survivors (5 or more years after diagnosis) of breast, prostate, and colorectal cancer are examined to identify the measurement properties and structure of general health and cancer-related health worries. Based on that measurement analysis, structural equation models (SEM) are used to estimate the relative importance of cancer-related and other illness predictors on cancer-related worry and general health worry and how these two forms of worry affect both anxiety (POMS) and depression (CES-D). The results from the exploratory and confirmatory factor analysis of health worries identify two relatively independent measures of health worry, one of general health worry and a second of cancer-related worries that includes fears of recurrence, new cancers, and follow-up testing. SEM analyses identified the importance of current cancer-related symptoms and comorbidities on cancer-related worry. It also documents the primacy of non-cancer symptoms and general health worry as predictors of anxiety and depression among older survivors. The fact that cancer-related symptoms continue to be associated with cancer-related worries years after diagnosis speaks to the significance of these continuing sequelae. While the findings suggest the relative independence of cancer-related worries and general health worries, both are correlated with anxiety and depression. This may be particularly problematic as survivors age and symptoms related to new health problems increase, while cancer-related symptoms persist. Copyright © 2015 John Wiley & Sons, Ltd.

A trustful relationship--the importance for relatives to actively participate in the meeting with the physician.

PubMed

Pennbrant, Sandra

2013-05-20

In previous research, no uniform picture emerged of the role of relatives in the meeting between an elderly patient and a physician. Knowledge about relatives' experiences of the meeting between an elderly patient and a physician will help healthcare practitioners better understand the role of relatives during the meeting and how practitioners can assist relatives in assuming their supporting role more efficiently. The purpose of this study is to explore experiences of relatives of meeting with the physician in a hospital setting when an elderly patient is discharged from hospital care to home care, in order to identify aspects that may facilitate relatives in taking up their role in a more efficient manner. This descriptive and exploratory study is based on 20 interviews with relatives. The result shows that the physician's communication style influences the meeting between the relative, the elderly patient, and the physician, and that this style is the result of power and interaction. A trustful relationship during the meeting between the relative and the physician can increase the relative's feeling of confidence with the healthcare organization and treatment of the elderly patient. The relative has an important supporting role in the care for the elderly family member, both in the hospital and the home setting. It is likely that the relative's value as a resource, for both the patient and the physician, increases as the relative experiences feelings of confidence in the meeting with the physician. It is therefore of value to increase our knowledge about the conditions and circumstances facilitating and/or hampering the meeting between the relative and the physician. The result stresses the importance of encouraging relatives to participate in the meeting. Physicians need more guidance and training in communication skills, respectful demeanor, and collaboration while meeting the relatives.

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational aggression in more diverse cultural contexts. This study examined the factor structure of, gender differences in, and associations between relational and physical aggression in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Children ages 7 to 10 years (N = 1410) reported on their relationally and physically aggressive behavior. Relational and physical aggression shared a common factor structure across countries. Unsurprisingly, boys reported being more physically aggressive than girls across all nine countries; surprisingly, there were no significant gender differences in relational aggression. In all nine countries, relational and physical aggression were significantly correlated (average r = .49). The countries differed significantly in the mean levels of both relational and physical aggression that children reported using and with respect to whether children reported using more physical than relational aggression or more relational than physical aggression. Despite mean level differences in relational and physical aggression across countries, the findings provided support for cross-country similarities in associations between relational and physical aggression, as well as links between gender and aggression.

Objective—To provide data on the magnitude and patterns of animal related on-farm injuries to youth in the United States. Data source—A survey of 26 000 farm households conducted for the National Institute for Occupational Safety and Health by the United States Department of Agriculture in 1998. Subjects—Youth younger than 20 years of age. Results—There were an estimated 6438 animal related on-farm injuries to youth in 1998. 70% occurred to farm residents; 69% were work related. Males accounted for 64% and approximately 41% occurred to those younger than 10; 37% involved horses and 31% cattle. Most horse related injuries occurred to females and a majority of the cattle related injuries were to males. Additionally, most of the cattle related injuries were work related, while horse related injuries were mainly non-work. Conclusions—One out of every five youth injuries occurring on farms in the United States is animal related. These animal related injuries were due to both work and non-work related exposures. The large number of horse and cattle related injuries highlights a need for intervention strategies based on the injury circumstances common to these animals. PMID:11770657

Psychiatric interest in relatives of patients was concentrated in the past on their pathogenetic and etiological influence on mental illness. The medical paradigma of mental illness did not account for relatives affliction in psychic disturbance of their family member. Against this a community care oriented approach involves relatives into psychiatric care, particularly under the aspects of coping strategies and rehabilitative sources. Practicability and effects of this approach were explored in expert-guided relative groups at the Psychiatric Hospital Gütersloh (FRG). Results indicated that relatives are concerned with a series of problems. Participating in relative groups facilitates coping with these problems. Expert-guided and relative centered groups were found helpful, discharging and encouraging for relatives.

Testing the Gamma-Ray Burst Energy Relationships

Band, David L.; Preece, Robert D.

2005-01-01

Building on Nakar & Piran's analysis of the Amati relation relating gamma-ray burst peak energies E(sub p) and isotropic energies E(sub iso ) we test the consistency of a large sample of BATSE bursts with the Amati and Ghirlanda (which relates peak energies and actual gamma-ray energies E(sub gamma)) relations. Each of these relations can be exp ressed as a ratio of the different energies that is a function of red shift (for both the Amati and Ghirlanda relations) and beaming fraction f(sub B) (for the Ghirlanda relation). The most rigorous test, whic h allows bursts to be at any redshift, corroborates Nakar & Piran's r esult - 88% of the BATSE bursts are inconsistent with the Amati relat ion - while only l.6% of the bursts are inconsistent with the Ghirlan da relation if f(sub B) = 1. Modelling the redshift distribution resu lts in an energy ratio distribution for the Amati relation that is sh ifted by an order of magnitude relative to the observed distributions; any sub-population satisfying the Amati relation can comprise at mos t approx. 18% of our burst sample. A similar analysis of the Ghirland a relation depends sensitively on the beaming fraction distribution f or small values of f(sub B); for reasonable estimates of this distrib ution about a third of the burst sample is inconsistent with the Ghir landa relation. Our results indicate that these relations are an artifact of the selection effects of the burst sample in which they were f ound; these selection effects may favor sub-populations for which the se relations are valid.

The effects of attention on age-related relational memory deficits: Evidence from a novel attentional manipulation

PubMed Central

Kim, So-Yeon; Giovanello, Kelly S.

2011-01-01

Healthy aging is often accompanied by episodic memory decline. Prior studies have consistently demonstrated that older adults show disproportionate deficits in relational memory (RM) relative to item memory (IM). Despite rich evidence of an age-related RM deficit, the source of this deficit remains unspecified. One of the most widely investigated factors of age-related RM impairment is a reduction in attentional resources. However, no prior studies have demonstrated that reduced attentional resources are the critical source of age-related RM deficits. Here, we utilized qualitatively different attention tasks, and tested whether reduced attention for relational processing underlies the RM deficit observed in aging. In Experiment 1, we imposed either item-detection or relation-detection attention tasks on young adults during episodic memory encoding, and found that only the concurrent attention task involving relational processing disproportionately impaired RM performance in young adults. Moreover, by ruling out the possible confound of task-difficulty on the disproportionate RM impairment, we further demonstrated that reduced relational attention is a key factor for the age-related RM deficit. In Experiment 2, we replicated the results from Experiment 1 using different materials of stimuli and found that the effect of relational attention on RM is material-general. The results of Experiment 2 also showed that reducing attentional resources for relational processing in young adults strikingly equated their RM performance to that of older adults. Thus, the current study documents the first evidence that reduced attentional resources for relational processing are a critical factor for the relational memory impairment observed in aging.

Cognitive tasks involving conflicting stimuli and responses are associated with an early age-related decline in performance. Conflict and conflict-induced interference can be stimulus- or response-related. In classical stimulus-response compatibility tasks, such as the Stroop task, the event-related potential (ERP) usually reveals a greater negativity on incongruent versus congruent trials which has often been linked with conflict processing. However, it is unclear whether this negativity is related to stimulus- or response-related conflict, thus rendering the meaning of age-related changes inconclusive. In the present study, a modified Stroop task was used to focus on stimulus-related interference processes while excluding response-related interference. Since we intended to study work-relevant effects ERPs and performance were determined in young (about 30 years old) and middle-aged (about 50 years old) healthy subjects (total n=80). In the ERP, a broad negativity developed after incongruent versus congruent stimuli between 350 and 650 ms. An age-related increase of the latency and amplitude of this negativity was observed. These results indicate age-related alterations in the processing of conflicting stimuli already in middle age.

The present study examined the relation of anxiety sensitivity to alcohol-related outcomes via coping drinking motives in college women. Further, the impact of emotion dysregulation on the mediational path between anxiety sensitivity and alcohol-related outcomes was investigated. A sample of 223 female undergraduate drinkers from a midwestern university completed self-report surveys assessing alcohol consumption, alcohol-related problems, anxiety sensitivity, coping drinking motives, and emotion dysregulation. Anxiety sensitivity was indirectly related to both alcohol-related problems and alcohol use via coping motives. The indirect effect of anxiety sensitivity on alcohol-related problems (but not alcohol use) was qualified by the level of emotion dysregulation. As individuals reported more emotion dysregulation, the strength of the relation between coping drinking motives and alcohol-related problems increased. Results replicate and extend the link between anxiety sensitivity and alcohol outcomes via the mechanism of negative reinforcement, and they further support the importance of emotion dysregulation in explaining alcohol-related problems among college women. Implications for treatment and prevention of alcohol-related problems in college women are discussed.

Office workers have a high prevalence of musculoskeletal conditions. This can be a significant economic burden due to health-related productivity loss. Individual and work-related factors related to office worker health-related productivity were investigated. A survey including the Health and Work Performance Questionnaire, which estimated productivity loss, also recorded individual and work-related factors with potential associations with health-related productivity. Muscle function and workstation ergonomics were examined through physical assessments. Linear models investigated the relationships between these factors and health-related productivity. Significant factors identified were occupational category (0.001 < P < 0.050), job satisfaction (P < 0.001), psychological wellbeing (P = 0.031), and musculoskeletal pain (P = 0.023). Health-related productivity loss was greater in office workers working as managers, with lower job satisfaction and psychological wellbeing, and those with musculoskeletal pain. Office worker health-related productivity loss is represented by a combination of both individual and work-related factors.

The organisation of spatial and temporal relations in memory.

Episodic memories are comprised of details of "where" and "when"; spatial and temporal relations, respectively. However, evidence from behavioural, neuropsychological, and neuroimaging studies has provided mixed interpretations about how memories for spatial and temporal relations are organised-they may be hierarchical, fully interactive, or independent. In the current study, we examined the interaction of memory for spatial and temporal relations. Using explicit reports and eye-tracking, we assessed younger and older adults' memory for spatial and temporal relations of objects that were presented singly across time in unique spatial locations. Explicit change detection of spatial relations was affected by a change in temporal relations, but explicit change detection of temporal relations was not affected by a change in spatial relations. Younger and older adults showed eye movement evidence of incidental memory for temporal relations, but only younger adults showed eye movement evidence of incidental memory for spatial relations. Together, these findings point towards a hierarchical organisation of relational memory. The implications of these findings are discussed in the context of the neural mechanisms that may support such a hierarchical organisation of memory.

Examining the relationship between selective attentional bias for food- and body-related stimuli and purging behaviour in bulimia nervosa.

PubMed

2016-12-01

Previous research exploring cognitive biases in bulimia nervosa suggests that attentional biases occur for both food-related and body-related cues. Individuals with bulimia were compared to non-bulimic controls on an emotional-Stroop task which contained both food-related and body-related cues. Results indicated that bulimics (but not controls) demonstrated a cognitive bias for both food-related and body-related cues. However, a discrepancy between the two cue-types was observed with body-related cognitive biases showing the most robust effects and food-related cognitive biases being the most strongly associated with the severity of the disorder. The results may have implications for clinical practice as bulimics with an increased cognitive bias for food-related cues indicated increased bulimic disorder severity.

Mougin, Fleur; Grabar, Natalia

2014-01-01

Objective This work focuses on multiply-related Unified Medical Language System (UMLS) concepts, that is, concepts associated through multiple relations. The relations involved in such situations are audited to determine whether they are provided by source vocabularies or result from the integration of these vocabularies within the UMLS. Methods We study the compatibility of the multiple relations which associate the concepts under investigation and try to explain the reason why they co-occur. Towards this end, we analyze the relations both at the concept and term levels. In addition, we randomly select 288 concepts associated through contradictory relations and manually analyze them. Results At the UMLS scale, only 0.7% of combinations of relations are contradictory, while homogeneous combinations are observed in one-third of situations. At the scale of source vocabularies, one-third do not contain more than one relation between the concepts under investigation. Among the remaining source vocabularies, seven of them mainly present multiple non-homogeneous relations between terms. Analysis at the term level also shows that only in a quarter of cases are the source vocabularies responsible for the presence of multiply-related concepts in the UMLS. These results are available at: http://www.isped.u-bordeaux2.fr/ArticleJAMIA/results_multiply_related_concepts.aspx. Discussion Manual analysis was useful to explain the conceptualization difference in relations between terms across source vocabularies. The exploitation of source relations was helpful for understanding why some source vocabularies describe multiple relations between a given pair of terms. PMID:24464853

Objectives Cannabis use motives are differentially related to cannabis-related impairment and coping motives appear to have the strongest relation to use-related impairment. However, it is currently unknown whether African American individuals differ from White persons in reasons for using cannabis. It is also unknown whether motives’ relations to cannabis use and related impairment vary as a function of race. The present study examined the role of race on cannabis use motives and tested whether motives’ relations with cannabis use and related impairment differed by race. Design The sample consisted of 111 (67.6% non-Hispanic White, 32.4% African American) current cannabis-using adults. Results African American participants did not significantly differ from White participants on cannabis use frequency or use-related impairment. African American participants endorsed more social motives than White participants. Race interacted with social, coping, and conformity motives to predict cannabis-related impairment such that these motives were positively related to cannabis impairment among African American, but not White, participants. Conclusion Although African American and White participants do not differ in their cannabis use frequency or cannabis-related impairment, they appear to use cannabis for different reasons. Further, conformity, coping, and social motives were differentially associated with cannabis-related impairment as a function of race. Findings suggest motives for cannabis use should be contexualized in the context of race. PMID:26264291

The author reviews and comments on the book Equivalence relations and behavior: a research story by Murray Sidman. Sidman's book reports his research about equivalence relations and competencies in children with mental retardation and how it relates to behavior. Sidman used the idea of stimulus-stimulus relations among features of the environment to develop his theories about equivalence relations. Experimental work with children and animals demonstrated their ability to use equivalence relations to learn new tasks. The subject received feedback and reinforcement for specific choices made during training, then was presented with new choices during testing. Results of the tests indicate that subjects were able to establish relations and retrieve them in different situations.

IgG4-related lymphadenopathy with increased numbers of Epstein-Barr virus (EBV)-infected cells has been reported but not fully described. We analyzed 31 cases of IgG4-related lymphadenopathy and 24 cases of extranodal IgG4-related diseases for their possible relationship with EBV. Other types of reactive lymph nodes (22) and angioimmunoblastic T-cell lymphoma (AITL) (10) were also studied for comparison. EBV-encoded RNA (EBER) in situ hybridization revealed EBER(+) cells in 18 of 31 cases (58%) of IgG4-related lymphadenopathy. Increased EBER(+) cells were found in only 4 of 22 (18.1%) non-IgG4-related reactive lymphoid hyperplasia in patients of a similar age (P=0.002) and in only 5 of 24 (21%) extranodal IgG4-related biopsies (P=0.006). Interestingly, all patients with EBER(+) progressively transformed germinal center-type IgG4-related lymphadenopathy had systemic lymphadenopathy and/or extranodal involvement. AITL also is associated with EBV, and IgG4-related lymphadenopathy sometimes mimics the morphology of AITL; however, the number of IgG4(+) cells in AITL was significantly less than that in IgG4-related lymphadenopathy (P<0.001). Increased numbers of regulatory T cells are seen in IgG4-related disease; however, there was not a significant difference between the EBER(+) and EBER(-) cases. In conclusion, the presence of increased numbers of EBV-infected cells in IgG4-related lymphadenopathy, compared with other reactive lymphadenopathy or extranodal IgG4-related disease, suggests that there may be a relationship at least between nodal IgG4-related disease and EBV. It is important to avoid overdiagnosing these cases as malignant lymphomas or EBV-related lymphoproliferative disorders.

Cost of Cancer-Related Neutropenia or Fever Hospitalizations, United States, 2012.

Neutropenia and subsequent infections are life-threatening treatment-related toxicities of chemotherapy. Among patients with cancer, hospitalizations related to neutropenic complications result in substantial medical costs, morbidity, and mortality. Previous estimates for the cost of cancer-related neutropenia hospitalizations are based on older and limited data. This study provides nationally representative estimates of the cost of cancer-related neutropenia hospitalizations. We examined data from the 2012 National Inpatient Sample and Kids' Inpatient Database. Hospitalizations for cancer-related neutropenia were defined as those with a primary or secondary diagnosis of cancer and a diagnosis of neutropenia or a fever of unknown origin. We examined characteristics of cancer-related neutropenia hospitalizations among children (age < 18 years) and adults (age ≥ 18 years). Adjusted predicted margins were used to estimate length of stay and cost per stay. There were 91,560 and 16,859 cancer-related neutropenia hospitalizations among adults and children, respectively. Total cost of cancer-related neutropenia hospitalizations was $2.3 billion for adults and $439 million for children. Cancer-related neutropenia hospitalizations accounted for 5.2% of all cancer-related hospitalizations and 8.3% of all cancer-related hospitalization costs. For adults, the mean length of stay for cancer-related neutropenia hospitalizations was 9.6 days, with a mean hospital cost of $24,770 per stay. For children, the mean length of stay for cancer-related neutropenia hospitalizations was 8.5 days, with a mean hospital cost of $26,000 per stay. We found the costs of cancer-related neutropenia hospitalizations to be substantially high. Efforts to prevent and minimize neutropenia-related complications among patients with cancer may decrease hospitalizations and associated costs.

Role of a texture gradient in the perception of relative size.

PubMed

Tozawa, Junko

2010-01-01

Two theories regarding the role of a texture gradient in the perception of the relative size of objects are compared. Relational theory states that relative size is directly specified by the projective ratio of the numbers of texture elements spanned by objects. Distance calibration theory assumes that relative size is a product of visual angle and distance, once the distance is specified by the texture. Experiment 1 involved three variables: background (no texture, texture gradient patterns), the ratio of heights of the comparison stimulus to a standard (three levels), and angular vertical separation of the standard stimulus below the horizon (two levels). The effect of the retinal length of the comparison stimulus was examined in experiment 2. In both experiments, participants judged both the apparent size and distance of a comparison stimulus relative to a standard stimulus. Results suggest that the cues selected by observers to judge relative size were to some degree different from those used to judge relative distance. Relative size was strongly affected by a texture gradient and the retinal length of a comparison stimulus whereas relative distance perception was affected by relative height. When dominant cues that specify size are different from those which specify distance, relational theory might provide a better account of relative size perception than distance calibration theory.

Persons living with HIV (PLHIV) are a health disparity subgroup of the overall population for mental and physical health problems. HIV-related stigma has been shown to increase anxiety symptoms and HIV symptoms among PLHIV. However, little is known about factors that may impact the relations between HIV-related stigma and anxiety symptoms and HIV symptoms among PLHIV. To address this gap in the literature, the current study examined anxiety sensitivity (i.e., the extent to which individuals believe anxiety and anxiety-related sensations) in the relation between HIV-related stigma, social anxiety, anxious arousal, and HIV symptoms among a sample of 87 PLHIV (60.9% cis gender male, 52.9% Black, non-Hispanic). Results indicated that anxiety sensitivity mediated the relations between HIV-related stigma and the dependent variables, with effect sizes indicating moderate to large effects of anxiety sensitivity on these relations. Findings suggest that anxiety sensitivity be a mechanistic factor in the relations between HIV-related stigma and social anxiety, anxious arousal, and HIV symptoms, and therefore, be important element in efforts to reduce mental/physical health disparity among this population.

2011-01-01

To describe injuries due to golf-related activities among pediatric patients requiring hospital admission. We conducted a retrospective analysis of all sports-related injuries from 2000 to 2006 using a level 1 trauma center database. Of 1005 children admitted with sports-related injuries, 60 (6%) had golf-related injuries. The mean injury severity score was significantly higher for golf-related injuries (11.0) than that for all other sports-related injuries (6.8). Most golf-related injuries occurred in children younger than 12 years (80%), at home (48%), and by a strike from a club (57%) and resulted in trauma to the head or neck (68%). Golf-related injuries, although an infrequent cause of sports-related injuries, have the potential to result in severe injuries, especially in younger children. Preventive efforts should target use of golf clubs by younger children in the home setting.

Quantify spatial relations to discover handwritten graphical symbols

NASA Astrophysics Data System (ADS)

Li, Jinpeng; Mouchère, Harold; Viard-Gaudin, Christian

2012-01-01

To model a handwritten graphical language, spatial relations describe how the strokes are positioned in the 2-dimensional space. Most of existing handwriting recognition systems make use of some predefined spatial relations. However, considering a complex graphical language, it is hard to express manually all the spatial relations. Another possibility would be to use a clustering technique to discover the spatial relations. In this paper, we discuss how to create a relational graph between strokes (nodes) labeled with graphemes in a graphical language. Then we vectorize spatial relations (edges) for clustering and quantization. As the targeted application, we extract the repetitive sub-graphs (graphical symbols) composed of graphemes and learned spatial relations. On two handwriting databases, a simple mathematical expression database and a complex flowchart database, the unsupervised spatial relations outperform the predefined spatial relations. In addition, we visualize the frequent patterns on two text-lines containing Chinese characters.

Comparison of relative and non-relative adoptive parent health status.

Across the United States, kinship parents, extended family members and close friends, render care to the 2.7 million children who have been removed from their birth parents' care. However, differences between relative and non-relative parents reported health statuses have not been explored. The National Survey of Adoptive Parents data were used to investigate the health status of relative (n = 469) and non-relative (n = 1,599) adoptive parents. Perceived happiness in the parent-child relationship and the parents' ability to cope appear to affect parental health status. Only non-related mothers of children younger than 6 years reported better emotional health than those mothers who were related to their children. With this exception, and despite caring for children who have a greater likelihood of abuse, neglect, and exposure to drugs and alcohol prior to birth, the reported health statuses of relative parents did not differ from non-relative parents. © The Author(s) 2013.

This study used nursing triage text to detect drug- and alcohol-related emergency department (ED) presentations and describe their patient and service delivery characteristics. Data were reviewed for all ED presentations from 2004 to 2006 (n = 263 937) from two hospitals in Sydney, Australia. Each record included two nursing triage free-text fields, which were searched for more than 100 drug-related and more than 60 alcohol-related terms. Adjusted odds ratios were used to compare the characteristics of drug and alcohol-related ED presentations with all other ED presentation types. Just over 5% of ED presentations were identified as alcohol-related and 2% as drug-related. The most prevalent drug-related ED presentations specified were related to amphetamines (18%), heroin (14%), cannabis (14%) and ecstasy (12%), while nearly half (43%) were drug unspecified. Polydrug use was mentioned in 25% of drug-related and 9% of alcohol-related ED presentations, with the highest rate of polydrug use among ecstasy-related (68%) presentations. Drug- and alcohol-related ED presentations were significantly more likely than other ED presentations to have a mental health diagnosis, with the highest rates found among cannabis-related (OR = 7.6) or amphetamine-related (OR = 7.5) presentations. The ED provides an opportunity for early intervention for patients presenting with comorbid drug and alcohol and mental health problems. Further research is needed to assess the prevalence of drug and alcohol problems in ED patients with mental health problems and to develop effective interventions in that setting.

Monogamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy relations related to the concurrence C , the entanglement of formation E , negativity Nc, and Tsallis-q entanglement Tq. Monogamy relations for the α th power of entanglement have been derived, which are tighter than the existing entanglement monogamy relations for some classes of quantum states. Detailed examples are presented.

Gender differences in the relative impact of physical and relational bullying on adolescent injury and weapon carrying.

PubMed

Dukes, Richard L; Stein, Judith A; Zane, Jazmin I

2010-12-01

Using structural equation modeling, concurrent associations were assessed among physical bullying, relational bullying, physical victimization, relational victimization, injury and weapon carrying using data from the population of 1300 adolescent girls and 1362 adolescent boys in grades 7-12 in a Colorado school district. For both genders, being a relational bully was a significantly stronger predictor of weapon carrying than being a physical bully, and both bullying types were significant predictors of more weapon carrying. For both genders, being a victim of physical bullying, a victim of relational bullying, or being a relational bully significantly predicted more injury. In latent means comparisons, adolescent girls reported more relational victimization and adolescent boys reported more physical bullying and victimization, more weapon carrying, and more injury. The relative strength of relational bullying on weapon carrying, and the health-related consequences of bullying on interpersonal violence and injury support concerted efforts in schools to mitigate these behaviors. Attention to differences related to age and gender also is indicated in the design of bullying mitigation programs. Copyright © 2010 Society for the Study of School Psychology.

Representing and querying now-relative relational medical data.

PubMed

Anselma, Luca; Piovesan, Luca; Stantic, Bela; Terenziani, Paolo

2018-03-01

Temporal information plays a crucial role in medicine. Patients' clinical records are intrinsically temporal. Thus, in Medical Informatics there is an increasing need to store, support and query temporal data (particularly in relational databases), in order, for instance, to supplement decision-support systems. In this paper, we show that current approaches to relational data have remarkable limitations in the treatment of "now-relative" data (i.e., data holding true at the current time). This can severely compromise their applicability in general, and specifically in the medical context, where "now-relative" data are essential to assess the current status of the patients. We propose a theoretically grounded and application-independent relational approach to cope with now-relative data (which can be paired, e.g., with different decision support systems) overcoming such limitations. We propose a new temporal relational representation, which is the first relational model coping with the temporal indeterminacy intrinsic in now-relative data. We also propose new temporal algebraic operators to query them, supporting the distinction between possible and necessary time, and Allen's temporal relations between data. We exemplify the impact of our approach, and study the theoretical and computational properties of the new representation and algebra. Copyright © 2018 Elsevier B.V. All rights reserved.

Does Humor Explain Why Relationally Aggressive Adolescents Are Popular?

Bowker, Julie C.; Etkin, Rebecca G.

2013-01-01

The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

Bullying is a public health concern for the school-aged population, however, the health outcomes associated with the subtype of relational bullying are less understood. The purpose of this study was to examine the association between relational bullying and health-related quality of life (HRQL) among young people. This study utilized data from 5335 students aged 11-15 years, collected as part of the 2014 Health Behavior in School-aged Children (HBSC) study conducted in England. Data were collected through self-completed surveys. Multilevel analysis modeled the relationship between relational bullying and HRQL. Demographic variables (sex, age, ethnicity, socioeconomic status) and other forms of bullying were controlled for. Experiencing relational bullying had a significant negative association with HRQL whilst controlling for other forms of bullying. Weekly relational bullying resulted in an estimated 5.352 (95% confidence interval (CI), -4.178, -6.526) decrease in KIDSCREEN-10 score compared with those not experiencing relational bullying. Experiencing relational bullying is associated with poorer HRQL. The findings question the perception of relational bullying as being a predominantly female problem. Girls were more likely to report experiencing relational bullying, but the negative association with HRQL was equal for boys and girls. © 2017, American School Health Association.

Drinking and Desired Self-Images: Path Models of Self-Image Goals, Coping Motives, Heavy-Episodic Drinking, and Alcohol Problems

Coping motives for drinking initiate alcohol-related problems. Interpersonal goals, which powerfully influence affect, could provide a starting point for this relation. Here we tested effects of self-image goals (which aim to construct and defend desired self-views) and compassionate goals (which aim to support others) on heavy-episodic drinking and alcohol-related problems. Undergraduate drinkers (N=258) completed measures of self-image and compassionate goals in academics and friendships, coping and enhancement drinking motives, heavy-episodic drinking, and alcohol-related problems in a cross-sectional design. As predicted, self-image goals, but not compassionate goals, positively related to alcohol-related problems. Path models showed that self-image goals relate to coping motives, but not enhancement motives; coping motives then relate to heavy-episodic drinking, which in turn relate to alcohol-related problems. Self-image goals remained a significant predictor in the final model, which accounted for 34% of the variance in alcohol-related problems. These findings indicate that self-image goals contribute to alcohol-related problems in college students both independently and through coping motives. Interventions can center on reducing self-image goals and their attendant negative affect. PMID:19586150

Although social anxiety is related to smoking and nicotine dependence, few researchers have sought to identify factors that contribute to these relations. The current study examined whether social anxiety was associated with cognitive vulnerability factors related to smoking: perceived barriers for quitting, cessation-related problems, negative-affect-reduction-outcome expectancies, and negative-affect-reduction motives. Further, we tested whether social anxiety was robustly related to these factors after controlling for cigarettes smoked per day, gender, alcohol-use frequency, lifetime cannabis-use status, panic attack frequency, anxiety sensitivity, and negative affectivity. The sample consisted of 580 (38.6% female) treatment-seeking smokers. Social anxiety was associated with perceived barriers for quitting, cessation-related problems, negative-affect-reduction-outcome expectancies, and negative-affect-reduction motives. After controlling for covariates, social anxiety was robustly related to perceived barriers for quitting, cessation-related problems, and negative-affect-reduction-outcome expectancies. Social anxiety was robustly related to negative-affect-reduction motives among men, but not women. Results indicate that social anxiety is robustly related to cognitive vulnerability factors associated with poorer cessation outcomes, suggesting that social anxiety may be an important therapeutic target during smoking cessation.

Major upper abdominal surgery is often associated with reduced health-related quality of life and reduced survival. Patients with upper abdominal malignancies often suffer from cachexia, represented by preoperative weight loss and sarcopenia (low skeletal muscle mass) and this might affect both health-related quality of life and survival. We aimed to investigate how health-related quality of life is affected by cachexia and how health-related quality of life relates to long-term survival after major upper abdominal surgery. From 2001 to 2006, 447 patients were included in a Norwegian multicenter randomized controlled trial in major upper abdominal surgery. In this study, six years later, these patients were analyzed as a single prospective cohort and survival data were retrieved from the National Population Registry. Cachexia was derived from patient-reported preoperative weight loss and sarcopenia as assessed from computed tomography images taken within three months preoperatively. In the original trial, self-reported health-related quality of life was assessed preoperatively at trial enrollment and eight weeks postoperatively with the health-related quality of life questionnaire Short Form 36. A majority of the patients experienced improved mental health-related quality of life and, to a lesser extent, deteriorated physical health-related quality of life following surgery. There was a significant association between preoperative weight loss and reduced physical health-related quality of life. No association between sarcopenia and health-related quality of life was observed. Overall survival was significantly associated with physical health-related quality of life both pre- and postoperatively, and with postoperative mental health-related quality of life. The association between health-related quality of life and survival was particularly strong for postoperative physical health-related quality of life. Postoperative physical health-related quality of life strongly correlates with overall survival after major upper abdominal surgery.

Objective : To determine whether there are significant differences between rapid-eye-movement (REM)-related obstructive sleep apnea (OSA) and non-REM (NREM)-related OSA, in terms of the demographic, anthropometric, and polysomnographic characteristics of the subjects. Methods : This was a retrospective study of 110 patients (75 males) with either REM-related OSA (n = 58) or NREM-related OSA (n = 52). To define REM-related and NREM-related OSA, we used a previously established criterion, based on the apnea-hypopnea index (AHI): AHI-REM/AHI-NREM ratio > 2 and ≤ 2, respectively. Results : The mean age of the patients with REM-related OSA was 49.5 ± 11.9 years, whereas that of the patients with NREM-related OSA was 49.2 ± 12.6 years. The overall mean AHI (all sleep stages combined) was significantly higher in the NREM-related OSA group than in the REM-related OSA group (38.6 ± 28.2 vs. 14.8 ± 9.2; p < 0.05). The mean AHI in the supine position (s-AHI) was also significantly higher in the NREM-related OSA group than in the REM-related OSA group (49.0 ± 34.3 vs. 18.8 ± 14.9; p < 0.0001). In the NREM-related OSA group, the s-AHI was higher among the men. In both groups, oxygen desaturation was more severe among the women. We found that REM-related OSA was more common among the patients with mild-to-moderate OSA, whereas NREM-related OSA was more common among those with severe OSA. Conclusions : We found that the severity of NREM-related OSA was associated mainly with s-AHI. Our findings suggest that the s-AHI has a more significant effect on the severity of OSA than does the AHI-REM. When interpreting OSA severity and choosing among treatment modalities, physicians should take into consideration the sleep stage and the sleep posture. PMID:26982041

Substance use disorders in adolescent and young adult relatives of probands with bipolar disorder: What drives the increased risk?

Adults with bipolar disorder (BD) have higher rates of substance use disorders (SUDs) compared to the general population. SUD rates in young offspring/relatives of BD probands, as well as factors which drive those rates, are not as well-characterized. We aimed to examine SUD prevalence among adolescent/young adult offspring and relatives of probands with and without BD. Data were collected from five sites in the US and Australia during 2006-2011. Youth offspring/relatives ("Relatives of BD probands;" n=267; mean age=16.8years; ±2.9S.D.), identified through a proband family member with DSM-IV BD (Type I or II), were compared to offspring/relatives of control probands ("relatives of control probands;" n=149; mean age=17.4years; ±2.9S.D.). Logistic regression with generalized estimating equations was used to compare the groups across a range of substance use and SUD variables. Odds ratios were calculated for lifetime prevalence of substance outcomes. Bivariate analyses showed DSM-IV SUDs were more prevalent among relatives of BD probands than among relatives of control probands (29% vs. 18%; p=0.01). Generalized estimating equation models showed BD mood and childhood-onset externalizing disorders in adolescent and young adult relatives to each significantly increase the odds (OR=2.80-3.17; p<0.02) for the development of several substance variables among all relatives, whereas the risk of SUDs in relatives was not increased when the relatives had no mood or externalizing disorders themselves. Relatives of BD probands with lifetime mood and externalizing disorders report more substance use/SUDs than relatives of control probands. In contrast, SUD outcomes in relatives of BD probands without mood or externalizing disorders were no different from control relatives without psychopathology. Early recognition and treatment of psychiatric disorders may lead to less substance use in this highly vulnerable population. Copyright © 2017 Elsevier Inc. All rights reserved.

The science of space-time

NASA Astrophysics Data System (ADS)

Raine, D. J.; Heller, M.

Analyzing the development of the structure of space-time from the theory of Aristotle to the present day, the present work attempts to sketch a science of relativistic mechanics. The concept of relativity is discussed in relation to the way in which space-time splits up into space and time, and in relation to Mach's principle concerning the relativity of inertia. Particular attention is given to the following topics: Aristotelian dynamics; Copernican kinematics; Newtonian dynamics; the space-time of classical dynamics; classical space-time in the presence of gravity; the space-time of special relativity; the space-time of general relativity; solutions and problems in general relativity; Mach's principle and the dynamics of space-time; theories of inertial mass; the integral formation of general relativity; and the frontiers of relativity (e.g., unified field theories and quantum gravity).

Are Categorical Spatial Relations Encoded by Shifting Visual Attention between Objects?

Uttal, David; Franconeri, Steven

2016-01-01

Perceiving not just values, but relations between values, is critical to human cognition. We tested the predictions of a proposed mechanism for processing categorical spatial relations between two objects—the shift account of relation processing—which states that relations such as ‘above’ or ‘below’ are extracted by shifting visual attention upward or downward in space. If so, then shifts of attention should improve the representation of spatial relations, compared to a control condition of identity memory. Participants viewed a pair of briefly flashed objects and were then tested on either the relative spatial relation or identity of one of those objects. Using eye tracking to reveal participants’ voluntary shifts of attention over time, we found that when initial fixation was on neither object, relational memory showed an absolute advantage for the object following an attention shift, while identity memory showed no advantage for either object. This result is consistent with the shift account of relation processing. When initial fixation began on one of the objects, identity memory strongly benefited this fixated object, while relational memory only showed a relative benefit for objects following an attention shift. This result is also consistent, although not as uniquely, with the shift account of relation processing. Taken together, we suggest that the attention shift account provides a mechanistic explanation for the overall results. This account can potentially serve as the common mechanism underlying both linguistic and perceptual representations of spatial relations. PMID:27695104

An association between salmeterol use and serious asthma episodes or asthma-related mortality has been noted in 2 clinical trials; however, a causal relationship has not been established. To date, observational studies have not replicated this finding. To examine the relationship between number of prescriptions dispensed of salmeterol-containing products and inhaled corticosteroid (ICS)-containing products and the rates of asthma-related hospitalizations and mortality in the United States. In this ecologic study, annual age-adjusted rates of asthma-related hospitalization and asthma-related mortality from US population-based sources were graphed alongside annual number of prescriptions dispensed of salmeterol- and ICS-containing products by year from 1991 to 2004. We computed the Spearman rank correlations between number of prescriptions dispensed and serious events (asthma-related hospitalization rate, number of hospitalizations, asthma-related mortality rate, and number of asthma deaths). During more than 14 years, while number of prescriptions dispensed of salmeterol-containing and ICS-containing products increased, age-adjusted asthma-related mortality rates declined and asthma-related hospitalization rates remained relatively stable. The number of asthma-related deaths has decreased steadily since the mid-1990s. This study provides population-level evidence that asthma-related death rates declined and asthma-related hospitalization rates remained relatively constant for more than 14 years during a period of improvements in asthma management per treatment guidelines, including increased use of maintenance medications, such as ICSs and salmeterol.

Short- and long-term impact of critical illness on relatives: literature review.

PubMed

Paul, Fiona; Rattray, Janice

2008-05-01

This paper is a report of a literature review undertaken to identify the short- and long-term impact of critical illness on relatives. Patients in intensive care can experience physical and psychological consequences, and their relatives may also experience such effects. Although it is recognized that relatives have specific needs, it is not clear whether these needs are always met and whether further support is required, particularly after intensive care. The following databases were searched for the period 1950-2007: Medline, British Nursing Index and Archive, EMBASE, CINAHL, PsycINFO and EMB Reviews--Cochrane Central Register of Clinical Trials. Search terms focused on adult relatives of critically ill adult patients during and after intensive care. Recurrent topics were categorized to structure the review, i.e. 'relatives needs', 'meeting relatives' needs', 'interventions', 'satisfaction', 'psychological outcomes' and 'coping'. Studies have mainly identified relatives' immediate needs using the Critical Care Family Needs Inventory. There are few studies of interventions to meet relatives' needs and the short- and long-term effects of critical illness on relatives. Despite widespread use of the Critical Care Family Needs Inventory, factors such as local or cultural differences may influence relatives' needs. Relatives may also have unidentified needs, and these needs should be explored. Limited research has been carried out into interventions to meet relatives' needs and the effects of critical illness on their well-being, yet some relatives may experience negative psychological consequences far beyond the acute phase of the illness.

Women in substance abuse treatment increasingly report weight-related concerns as motivation for drug use. However, limited research has explored the nature of these concerns or examined whether women in substance abuse treatment with weight-related concerns related to drug use differ from those who do not on variables relevant to eating pathology. Using a sample of 297 women in substance abuse treatment, this study examined two intertwined issues: (1) the prevalence and nature of weight-related concerns related to drug use and (2) whether women who endorse weight-related concerns related to drug use differ from those without weight-related concerns on body dissatisfaction, eating pathology, perceived pressure and internalization of thin-ideal media, and appearance-related drug-use expectancies. Descriptive analyses indicated that the majority of participants were concerned about gaining weight during treatment and/or that weight gain could trigger drug relapse. Analyses of variance revealed that women who reported weight-based concerns (both with regards to weight gain during treatment and relapse potential) endorsed higher levels of body dissatisfaction, dieting, bulimic symptoms, and thin-ideal internalization than women who did not endorse weight-related concerns. Results suggest that substance abuse treatment programs should be aware of and address weight-related concerns around drug use for women. Copyright © 2013 Elsevier Inc. All rights reserved.

Does drinking refusal self-efficacy mediate the impulsivity-problematic alcohol use relation?

There is consistent evidence that impulsivity-like traits relate to problematic alcohol involvement; however, identifying mechanisms that account for this relation remains an important area of research. Drinking refusal self-efficacy (or a person's ability to resist alcohol; DRSE) has been shown to predict alcohol use among college students and may be a relevant mediator of the impulsivity-alcohol relation. The current study examined the indirect effect of various constructs related to impulsivity (i.e., urgency, sensation seeking, and deficits in conscientiousness) via several facets of DRSE (i.e., social pressure, opportunistic, and emotional relief) on alcohol-related problems among a large sample of college students (N=891). Overall, results indicated that certain DRSE facets were significant mediators of the relation between impulsivity-related constructs and alcohol problems. More specifically, emotional-relief DRSE was a mediator for the respective relations between urgency and deficits in conscientiousness and alcohol problems, whereas social-DRSE was a significant mediator of the respective relations between urgency and sensation seeking with alcohol problems. Results from this study suggest particular types of DRSE are important mediators of the relations between specific impulsivity constructs and alcohol-related problems. These findings support prevention and intervention efforts that seek to enhance drinking refusal self-efficacy skills of college students, particularly those high in certain personality features, in order to reduce alcohol-related problems among this population.

Do community characteristics predict alcohol-related crime?

2011-01-01

Alcohol-related crime is a substantial community problem. There is evidence to suggest that certain geographic areas experience higher rates of alcohol-related crime and that both individual and community factors are associated with alcohol-related crime. There is limited research at the community level despite communities being the target of interventions designed to reduce alcohol-related harm. This study aims to determine whether there are differences in alcohol-related crime at the community level and examines whether certain community characteristics are associated with increased alcohol-related crime. Routinely collected police data from 20 rural communities in New South Wales, Australia were analysed. The ratio of alcohol to non-alcohol-related criminal incidents was used as a proxy for alcohol-related crime. Predictor variables were population-adjusted community characteristics, including demographic and resource variables. Regression analyses suggest that there are differences between communities in alcohol-related crime. Less socioeconomic disadvantage and more GPs and licensed premises (pubs and clubs) are associated with greater alcohol-related crime at the community level. Decreasing the socioeconomic well-being of a community is not appropriate; however, introducing additional taxes to increase the cost of alcohol may decrease consumption and therefore alcohol-related crime. Reducing or capping the number of licensed premises, specifically the number of pubs and clubs, may be an appropriate strategy to reduce alcohol-related crime in rural communities.

The role of emotion regulation in the relations between psychopathy factors and impulsive and premeditated aggression.

Given the high rates of aggressive behavior among highly psychopathic individuals, much research has sought to clarify the nature of the relation between psychopathy and aggression. The present study examined relations between Fearless Dominance (PPI FD), Self-Centered Impulsivity (PPI SCI), and Coldheartedness (PPI CH) Factors of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and aggression dimensions (premeditated and impulsive aggression) in a sample of substance users receiving inpatient treatment. At the univariate level, PPI FD traits were significantly and positively related to premeditated aggression, but were not significantly related to impulsive aggression. PPI SCI traits were positively related to both forms of aggression, whereas PPI CH was not significantly related to either aggression dimension. Emotion regulation difficulties, as measured by the Difficulties with Emotion Regulation Scale (DERS; Gratz & Roemer, 2004), were negatively related to PPI FD traits, positively related to PPI SCI traits, and negatively related to PPI CH traits. Both PPI SCI and PPI FD traits exerted significant indirect effects on impulsive aggression through the DERS. In contrast, the DERS did not mediate the relations between psychopathic traits and premeditated aggression. Results provide a more nuanced understanding of the psychopathy-aggression relations and suggest that difficulties with emotion regulation may be an important mediator of the relations between psychopathy factors and impulsive aggression.

Beliefs about unmet interpersonal needs mediate the relation between conflictual family relations and borderline personality features in young adult females.

2014-01-01

Central to most theories of borderline personality disorder (BPD) is the notion that the family environment interacts with genetically-based vulnerabilities to influence the development of BPD, with particular attention given to risk conferred by conflictual familial relations. However, the extent to which family conflict may relate to the development of BPD via related interpersonal beliefs is currently unknown. This study sought to test the hypothesis that the concurrent relation between conflictual family relations and borderline features in female college students is explained by beliefs associated with real or perceived unmet interpersonal needs (captured by Joiner's [2005] Interpersonal Psychological Theory, specifically thwarted belongingness and perceived burdensomeness). The sample included 267 female undergraduates ages 18-25 years (M = 20.86; SD = 1.80). Level of borderline personality features, unmet interpersonal needs, and family conflict were assessed. Bivariate analyses revealed significant relations between both thwarted belongingness and perceived burdensomeness, conflictual family relations, and borderline features. Multivariate analyses revealed that thwarted belongingness and perceived burdensomeness both mediated the relation between family conflict and borderline personality features, thus supporting a multiple mediation model. This cross-sectional study is a preliminary step towards confirming the broad theoretical hypothesis that conflictual family relations relate to beliefs about thwarted belongingness and perceived burdensomeness, which, in turn, relate to borderline personality pathology. Limitations and areas of future research are discussed.

Bidirectional Relations between Phonological Awareness and Letter Knowledge in Preschool Revisited: A Growth Curve Analysis of the Relation between Two Code-Related Skills

Despite the importance of phonological awareness for the development of reading in alphabetic languages, little attention has been paid to its developmental origins. In this study, dual-process, latent growth models were used to examine patterns of bidirectional relations between letter knowledge and phonological awareness during preschool. The sample comprised 358 children (mean age = 48.60 months, SD = 7.26). Growth models were used to quantify the unique longitudinal relations between the initial level of each skill and growth in the other skill during the preschool year, after controlling for initial level of the same skill, vocabulary, age, and growth in the code-related skill being used as a predictor. Letter-name knowledge and phonological awareness were bi-directionally related; the initial level of each uniquely predicted growth in the other. Initial letter-sound knowledge and phonological awareness growth were not uniquely related, and vocabulary was not related to growth in phonological awareness. These findings extend the evidence of the relation between letter knowledge and phonological awareness to supra-phonemic tasks, indicating that this bidirectional relation begins at an earlier point in the development of phonological awareness than previously reported. In addition, these findings help to rule out general growth in letter knowledge and phonological awareness as an alternative explanation for the bidirectional relation between these two code-related skills.

Essentials It is unknown if a male or female thrombotic family history influences risk in female relatives. We assessed thrombotic risk in female relatives of male and female patients with thrombosis. A hormonally related female thrombotic family history further increases risk in female relatives. This information could be important in counseling women on contraceptive options. Click to hear Prof. Rosendaal's perspective on venous thrombosis: etiology, pathogenesis, and prognosis Background Women from thrombophilic families have increased risk of venous thromboembolism (VTE), which increases further during oral contraceptive (COC) use and pregnancy-postpartum. Whether this additional risk differs between relatives of male and female patients, or is different when that female patient had a hormonally related VTE (during COC use/pregnancy), is unknown. Methods One thousand five female relatives of consecutive patients with VTE from a family-based cohort were retrospectively followed for incident VTE from ages 15 to 50, first VTE, or study inclusion. Absolute and relative VTE risks adjusted for factors of patients (sex, age) and relatives (thrombophilia, COC use, pregnancy) were estimated in relatives of female and male patients and in relatives of female patients with and without hormonally related VTE. Results Absolute risk in relatives of female (0.32 [95% confidence interval [CI] 0.23-0.43]) vs. male patients (0.39 [95% CI 0.28-0.53]) was comparable. However, the heterogeneity analysis of risk estimates suggested that in relatives of female vs. male patients, the contribution of pregnancy-postpartum (hazard ratio [HR] 11.6 [95% CI 6.3-21.3] vs. HR6.6 [95% CI 2.8-15.2]) and, to a lesser extent, COC use (HR3.6 [95% CI 1.8-7.1] vs. HR2.7 [95% CI 1.5-5.0]) to the VTE risk differs. Absolute risk was significantly higher in relatives of female patients with hormonally related VTE (0.43 [95% CI 0.3-0.6]) vs. relatives of female patients without hormonally related VTE (0.13 [95% CI 0.05-0.27]), HR3.28 [95% CI 1.5-7.9]). The higher contribution of pregnancy-postpartum and COC use to the VTE risk was mainly observed in relatives of patients with hormonally related VTE. Conclusions These findings suggest that a family history from a female patient, especially when VTE was hormonally related, may further increase VTE risk in her female relatives. This information could be important in counseling women on contraceptive options. © 2016 The Authors.

Although obesity is associated with hepatocellular carcinoma (HCC) development, its impact on the surgical outcomes of patients with hepatitis B virus (HBV)-and hepatitis C virus (HCV)-related HCC remains unclear. We retrospectively analyzed 714 patients with HCC who underwent curative hepatectomy. Among them, the HBV-related HCC group (n = 125) and HCV-related HCC group (n = 426) were subdivided according to the presence of body mass index (BMI) ≥ 25 kg/m 2 . The surgical outcomes were compared. The 5-year overall survival rate after hepatectomy in the HBV-related HCC group was significantly better than that in the HCV-related HCC group. The 5-year overall survival rates of the HBV-related HCC with and without BMI ≥ 25 kg/m 2 groups were 65 and 85%, respectively. The 5-year overall survival rates in the HCV-related HCC with and without BMI ≥ 25 kg/m 2 groups were 75 and 65%, respectively. The HBV-related HCC with BMI ≥ 25 kg/m 2 groups had a significantly worse prognosis than the HBV-related HCC without BMI ≥ 25 kg/m 2 groups, while the HCV-related HCC with BMI ≥ 25 kg/m 2 groups had a significantly better prognosis than the HCV-related HCC without BMI ≥ 25 kg/m 2 groups. Multivariate analysis revealed that BMI ≥ 25 kg/m 2 was the positive and negative prognostic factor for the surgical outcomes of patients with HBV- and HCV-related HCC, respectively. BMI ≥ 25 kg/m 2 negatively affected the surgical outcomes of patients with HBV-related HCC and positively affected those of patients with HCV-related HCC.

The purposes of the present study are to determine the prevalence and demographic features of rapid eye movement (REM)-related sleep-disordered breathing (SDB) in Korean adults with newly diagnosed obstructive sleep apnea (OSA) and determine if REM-related SDB is associated with depressive symptoms and health-related quality of life (HRQoL) in OSA patients. In this cross-sectional study, we evaluated 1281 OSA adults who were consecutively recruited. REM-related SDB was defined as an overall apnea-hypopnea index (AHI) ≥5, an AHINREM <15, and AHIREM to AHINREM ratio of >2. The Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Medical Outcomes Study Short-Form Health survey (SF-36) were used to evaluate all patients. Multiple regression analyses were performed to determine the associations between REM-related SDB and clinical outcomes. The prevalence of REM-related SDB was 18 % in this study. REM-related SDB was more commonly observed in patients with mild or moderate OSA (p < 0.001) and women (p < 0.001). The linear regression analysis showed that the presence of REM-related SDB was significantly associated with higher BDI scores, but only in men. AHIREM was positively associated with the BDI scores, but only in men with REM-related SDB. There were no differences in ESS and SF-36 scores between patients with and without REM-related SDB. Patients with REM-related SDB account for 18 % of Korean OSA adults. REM-related SDB was associated with depressive symptoms, but only in men. AHIREM is positively related to the degree of depressive symptoms in men with REM-related SDB.

Auditing the multiply-related concepts within the UMLS.

Mougin, Fleur; Grabar, Natalia

2014-10-01

This work focuses on multiply-related Unified Medical Language System (UMLS) concepts, that is, concepts associated through multiple relations. The relations involved in such situations are audited to determine whether they are provided by source vocabularies or result from the integration of these vocabularies within the UMLS. We study the compatibility of the multiple relations which associate the concepts under investigation and try to explain the reason why they co-occur. Towards this end, we analyze the relations both at the concept and term levels. In addition, we randomly select 288 concepts associated through contradictory relations and manually analyze them. At the UMLS scale, only 0.7% of combinations of relations are contradictory, while homogeneous combinations are observed in one-third of situations. At the scale of source vocabularies, one-third do not contain more than one relation between the concepts under investigation. Among the remaining source vocabularies, seven of them mainly present multiple non-homogeneous relations between terms. Analysis at the term level also shows that only in a quarter of cases are the source vocabularies responsible for the presence of multiply-related concepts in the UMLS. These results are available at: http://www.isped.u-bordeaux2.fr/ArticleJAMIA/results_multiply_related_concepts.aspx. Manual analysis was useful to explain the conceptualization difference in relations between terms across source vocabularies. The exploitation of source relations was helpful for understanding why some source vocabularies describe multiple relations between a given pair of terms.

Objective To determine if people with low back pain (LBP) who regularly participated in a rotation-related activity displayed more rotation-related impairments than people without LBP who did and did not participate in the activity. Design Secondary analysis of data from a case-control study. Setting Musculoskeletal analysis laboratory at an academic medical center. Participants A convenience sample of 55 participants with LBP who participated in a rotation-related sport, 26 back healthy controls who participated in a rotation-related sport (BHC+RRS) and 42 back healthy controls who did not participate in a rotation-related sport (BHC-RRS). Participants were matched based on age, gender, and activity level. Interventions Not applicable. Main Outcome Measures The total number of rotation-related impairments and asymmetric rotation-related impairments identified during a standardized clinical examination. Results Compared to the BHC-RRS group, both the LBP and BHC+RRS groups displayed significantly more (1) rotation-related impairments (LBP: p<.001; BHC+RRS: p=.015) (2) asymmetric rotation-related impairments (LBP: p=.006; BHC+RRS: p=.020) and (3) rotation-related impairments with trunk movement tests (LBP: p=.002; BHC+RRS: p<.001). The LBP group had significantly more rotation-related impairments with extremity movement tests than both of the back healthy groups (BHC+RRS: p=.011; BHC-RRS: p<.001). Conclusions LBP and BHC+RRS groups demonstrated a similar number of total rotation-related impairments and asymmetric rotation-related impairments, and these numbers were greater than those of the BHC-RRS group. Compared to people without LBP, people with LBP displayed more rotation-related impairments when moving an extremity. These findings suggest that impairments associated with extremity movements may be associated with having a LBP condition. PMID:25933914

Guidelines about palliative sedation typically include recommendations to protect the well-being of relatives. The aim of this study was to systematically review evidence on the experiences of relatives with the practice of palliative sedation. PubMed, Embase, Web of Science, PsycINFO, and CINAHL were searched for empirical studies on relatives' experiences with palliative sedation. We investigated relatives' involvement in the decision-making and sedation processes, whether they received adequate information and support, and relatives' emotions. Of the 564 studies identified, 39 were included. The studies (30 quantitative, six qualitative, and three mixed methods) were conducted in 16 countries; three studies were based on relatives' reports, 26 on physicians' and nurses' proxy reports, seven on medical records, and three combined different sources. The 39 studies yielded a combined total of 8791 respondents or studied cases. Caregivers involved relatives in the decision making in 69%-100% of all cases (19 quantitative studies), and in 60%-100% of all cases, relatives were reported to have received adequate information (five quantitative studies). Only two quantitative studies reported on relatives' involvement in the provision of sedation. Despite the fact that the majority of relatives were reported to be comfortable with the use of palliative sedation (seven quantitative studies, four qualitative studies), several studies found that relatives were distressed by the use of sedation (five quantitative studies, five qualitative studies). No studies reported specifically about the support provided to the relatives. Relatives' experiences with palliative sedation are mainly studied from the perspective of proxies, mostly professional caregivers. The majority of relatives seems to be comfortable with the use of palliative sedation; however, they may experience substantial distress by the use of sedation.

Pearson, Matthew R.; Hustad, John T. P.

2014-01-01

The present study examined three alcohol-perception variables (descriptive norms, injunctive norms, and college-related alcohol beliefs) as mediators of the predictive effects of four personality traits (impulsivity, sensation seeking, anxiety sensitivity, and hopelessness) on alcohol use and alcohol-related consequences in a sample of mandated college students (n = 875). Our findings replicated several findings of a previous study of incoming freshman college students (Hustad et al., in press) in that impulsivity and hopelessness had direct effects on alcohol-related problems, sensation seeking and impulsivity had indirect effects on alcohol-related outcomes via college-related alcohol beliefs, and college-related alcohol beliefs predicted both alcohol use and alcohol-related problems. We discuss the implications of our findings for global college student interventions as well as personality-targeted interventions. PMID:24589869

2014-07-01

Studies on cognitive effects of positive emotions have associated positive emotions to broadened attention. Given the widely investigated relationship between self-focused attention and mood, it is important to investigate the effect of positive mood on visuospatial attention for self-related information. We used a performance-based measure to assess fluctuations in attentional broadening from self-related contrasted to not-self-related information. In Experiment 1, we checked that the self-related versus not-self-related stimuli did not evoke differential attention effects in general. In Experiment 2, we manipulated mood and found that an increase in positive mood was associated with a relative broadening of attention for self-related information. These results suggest that the meaning of the target of attention provides an interesting dimension for further investigation into the relation between positive emotions and attentional broadening.

to survey the most common and the most important drug-related problems in Lithuania, to explore their solution and factors influencing it, to formulate recommendations for solving drug-related problems. Pharmacists from community pharmacies participated in a random survey. They filled in questionnaires about drug-related problems and their solutions. It was the first survey on drug-related problems ever carried out in Lithuania. For the first time, it was found out that in Lithuania pharmacists most commonly encountered drug-related problem--additional drug therapy (52.03% of respondents)--and most rarely encountered drug-related problem--dosage too high (3% of respondents). Pharmacists stated that all categories of drug-related problems were of equal importance. It was established that pharmacists commonly solved drug-related problems associated with noncompliance with instructions (72.5% of respondents) and rarely met the problem when improper drug was selected (39.56% of respondents). Patients taking prescription medicines commonly encounter additional drug therapy problem, and patients taking nonprescription medications commonly encounter problems related to noncompliance with instructions.

The study identified relations among traumatic stressors, HIV-related trauma symptoms, comorbid medical conditions, and health related quality of life (HRQL) in individuals with HIV. Participants (N = 118) completed a structured clinical interview on HIV as a traumatic stressor and other severe traumatic stressors and completed the Impact of Event Scale to assess HIV-related trauma symptoms and the Medical Outcomes Study 36-item Short Form (SF-36) to assess HRQL. Medical chart reviews determined comorbid conditions. Path analysis findings indicated participants with prior severe traumatic stressors experienced their HIV diagnosis as traumatic and in turn were more likely to have current HIV-related trauma symptoms which were negatively related to HRQL. HIV as a traumatic stressor was related to coronary artery diseases and HRQL. Traumatic stressors and HIV-related trauma symptoms impact health in individuals with HIV and highlight the need for psychological interventions prior to diagnosis and throughout treatment.

2012-02-01

We analysed the organisation of semantic network using associative mechanisms between different types of information and studied the progression of the use of these associative relations during development. We aimed to verify the linkage of concepts with the use of semantic associative relations. The goal of this study was to analyse the cognitive ability to use associative relations between various items when describing old and/or new concepts. We examined the performance of 100 subjects between the ages of 4 and 7 years on an experimental task using five associative relations based on verbal encoding. The results showed that children are able to use the five semantic associative relations at age 4, but performance with each of the different associative relations improves at different times during development. Functional and part/whole relations develop at an early age, whereas the superordinate relations develop later. Our study clarified the characteristics of the progression of semantic associations during development as well as the roles that associative relations play in the structure and improvement of the semantic store.

PREVALENCE AND PSYCHOSOCIAL CORRELATES OF ALCOHOL-RELATED SEXUAL ASSAULT AMONG UNIVERSITY STUDENTS

2009-01-01

This study examined the psychosocial correlates of alcohol-related sexual assault. Undergraduate students (N = 551) were recruited to complete a web-based survey. The outcome was a composite of 2 items: “experienced an unwanted sexual advance” or “was the victim of sexual assault or date rape” as a result of another’s alcohol use. The predictors were substance use, other alcohol-related interpersonal violence victimization, and alcohol-related protective behaviors. Multivariate logistic regression analyses were conducted. Females reported higher prevalence of alcohol-related sexual assault than did males (20.4% vs. 6.6%). Females who reported binge drinking (OR = 7.74) and other alcohol-related interpersonal violence (OR = 5.03) were more likely to report alcohol-related sexual assault whereas only other alcohol-related interpersonal violence was associated with alcohol-related sexual assault (OR = 43.75) among males. The findings suggest that alcohol-related sexual assault is associated with other risk factors that deserve further attention through longitudinal research and intervention efforts. PMID:19149143

We estimated net annual temperature-related mortality in Brisbane, Sydney and Melbourne in Australia using 62 global climate model projections under three IPPC SRES CO2 emission scenarios (A2, A1B and B1). In all cities, all scenarios resulted in increases in summer temperature-related deaths for future decades, and decreases in winter temperature-related deaths. However, Brisbane and Sydney will increase the net annual temperature-related deaths in the future, while a slight decrease will happen in Melbourne. Additionally, temperature-related mortality will largely increase beyond the summer (including January, February, March, November and December) in Brisbane and Sydney, while temperature-related mortality will largely decrease beyond the winter in Melbourne. In conclusion, temperature increases for Australia are expected to result in a decreased burden of cold-related mortality and an increased burden of heat-related mortality, but the balance of these differences varied by city. In particular, the seasonal patterns in temperature-related deaths will be shifted. Copyright © 2015 Elsevier Ltd. All rights reserved.

Monogamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy relations related to the concurrence C and the entanglement of formation E. We present new entanglement monogamy relations satisfied by the α -th power of concurrence for all α ≥ 2, and the α -th power of the entanglement of formation for all α ≥ √{2}. These monogamy relations are shown to be tighter than the existing ones.

Drinking and desired self-images: path models of self-image goals, coping motives, heavy-episodic drinking, and alcohol problems.

PubMed

Moeller, Scott J; Crocker, Jennifer

2009-06-01

Coping motives for drinking initiate alcohol-related problems. Interpersonal goals, which powerfully influence affect, could provide a starting point for this relation. Here we tested effects of self-image goals (which aim to construct and defend desired self-views) and compassionate goals (which aim to support others) on heavy-episodic drinking and alcohol-related problems. Undergraduate drinkers (N=258) completed measures of self-image and compassionate goals in academics and friendships, coping and enhancement drinking motives, heavy-episodic drinking, and alcohol-related problems in a cross-sectional design. As predicted, self-image goals, but not compassionate goals, positively related to alcohol-related problems. Path models showed that self-image goals relate to coping motives, but not enhancement motives; coping motives then relate to heavy-episodic drinking, which in turn relate to alcohol-related problems. Self-image goals remained a significant predictor in the final model, which accounted for 34% of the variance in alcohol-related problems. These findings indicate that self-image goals contribute to alcohol-related problems in college students both independently and through coping motives. Interventions can center on reducing self-image goals and their attendant negative affect. Copyright (c) 2009 APA, all rights reserved.

Personality and Stressor-Related Affect

2015-01-01

Greater increases in negative affect and greater decreases in positive affect on days stressors occur portend poorer mental and physical health years later. Although personality traits influence stressor-related affect, only neuroticism and extraversion among the Big Five personality traits have been examined in any detail. Moreover, personality traits may shape how people appraise daily stressors, yet few studies have examined how stressor-related appraisals may account for associations between personality and stressor-related affect. Two studies used participants (N=2022, age 30–84) from the National Study of Daily Experiences II (NSDE II) to examine the associations between Big Five personality traits and stressor-related affect, in addition to how appraisals may account for these relationships. Results from Study 1 indicate that higher levels of extraversion, conscientiousness, and openness to experience, and lower levels of neuroticism, are related to less stressor-related negative affect. Only agreeableness was associated with stressor-related positive affect, such that higher levels were related to greater decreases in positive affect on days stressors occur. The second study found that stressor-related appraisals partially accounted for the significant associations between stressor-related negative affect and personality. Implications for these findings in relation to how personality may influence physical and emotional health are discussed. PMID:26796984

Healthcare Mistreatment and Continuity of Cancer Screening among Latino and Anglo American Women in Southern California

2011-01-01

The aim of this research was to examine the relation of perceptions of healthcare mistreatment and related emotions to continuity of cancer screening care among women who reported healthcare mistreatment. The structure of relations among cultural beliefs about healthcare professionals, perceptions of mistreatment, mistreatment-related emotions, and continuity of screening was investigated. Participants included 313 Anglo and Latino American women of varying demographic characteristics from Southern California who were recruited using multistage stratified sampling. Structural equation modeling confirmed the relation of perceptions of mistreatment to continuity of care for both Anglo and Latino American women, with ethnicity moderating this association. For Anglo Americans, greater perceptions of mistreatment were negatively related to continuity of screening. However, for Latinas the relation was indirect, through mistreatment-related anger. While greater perceptions of mistreatment were associated with higher levels of anger for both ethnic groups, anger was negatively related to continuity of care for Latino but not for Anglo women. Furthermore, cultural beliefs about professionals were indirectly related to continuity of screening through perceptions of mistreatment and/or mistreatment-related anger. These findings highlight the importance of the role of cultural and psychological factors in research and interventions aimed at improving patient-professional relations with culturally diverse women.

Temporal context, preference, and resistance to change.

Podlesnik, Christopher A; Jimenez-Gomez, Corina; Thrailkill, Eric A; Shahan, Timothy A

2011-09-01

According to behavioral momentum theory, preference and relative resistance to change in concurrent-chains schedules are correlated and reflect the relative conditioned value of discriminative stimuli. In the present study, we explore the generality of this relation by manipulating the temporal context within a concurrent-chains procedure through changes in the duration of the initial links. Consistent with previous findings, preference for a richer terminal link was less extreme with longer initial links across three experiments with pigeons. In Experiment 1, relative resistance to change and preference were related inversely when responding was disrupted with response-independent food presentations during initial links, replicating a previous finding with rats. However, more food was presented with longer initial links, confounding the disrupter and initial-link duration. In Experiment 2, presession feeding was used instead and eliminated the negative relation between relative resistance to change and preference, but relative resistance to change was not sensitive to relative terminal-link reinforcement rates. In Experiment 3, with more extreme relative terminal-link reinforcement rates, increasing initial-link duration similarly decreased preference and relative resistance to change for the richer terminal link. Thus, when conditions of disruption are equal and assessed under the appropriate reinforcement conditions, changes in temporal context impact relative resistance to change and preference similarly.

Abstract In model organisms, over 2,000 genes have been shown to modulate aging, the collection of which we call the ‘gerontome’. Although some individual aging-related genes have been the subject of intense scrutiny, their analysis as a whole has been limited. In particular, the genetic interaction of aging and age-related pathologies remain a subject of debate. In this work, we perform a systematic analysis of the gerontome across species, including human aging-related genes. First, by classifying aging-related genes as pro- or anti-longevity, we define distinct pathways and genes that modulate aging in different ways. Our subsequent comparison of aging-related genes with age-related disease genes reveals species-specific effects with strong overlaps between aging and age-related diseases in mice, yet surprisingly few overlaps in lower model organisms. We discover that genetic links between aging and age-related diseases are due to a small fraction of aging-related genes which also tend to have a high network connectivity. Other insights from our systematic analysis include assessing how using datasets with genes more or less studied than average may result in biases, showing that age-related disease genes have faster molecular evolution rates and predicting new aging-related drugs based on drug-gene interaction data. Overall, this is the largest systems-level analysis of the genetics of aging to date and the first to discriminate anti- and pro-longevity genes, revealing new insights on aging-related genes as a whole and their interactions with age-related diseases.

Boredom at work: proximal and distal consequences of affective work-related boredom.

PubMed

van Hooff, Madelon L M; van Hooft, Edwin A J

2014-07-01

Boredom is an emotion that occurs regularly at the workplace, with negative consequences for the employee and the organization. It is therefore important to understand why work-related boredom leads to such adverse consequences and what can be done to mitigate its occurrence and its negative consequences. In the present study we proposed a model suggesting that feelings of boredom at work induce immediate affect-based bored behaviors, and that such bored behavior leads to depressive complaints, distress, and counterproductive work behavior. We further posed that job crafting can mitigate work-related boredom and its negative outcomes. Results of a survey study among 189 employees showed that work-related boredom and bored behavior are empirically distinct, though related, constructs. Work-related boredom was positively related to depressive complaints, distress, and counterproductive work behavior, and these associations were fully mediated by bored behavior. Job crafting related negatively to work-related boredom, and attenuated the relationship of work-related boredom with bored behavior. Moreover, the indirect effects of work-related boredom through bored behavior on its outcomes were smaller the more employees engaged in job crafting. This research enhances insight into work-related boredom by showing that boredom as an affective state can be distinguished from its proximal behavioral consequences, and by providing a first onset to obtain insight in moderating and mediating mechanisms that may explain work-related boredom's consequences. It highlights the importance of employees' opportunities to work in jobs that do not cause work-related boredom to develop, and the role of job crafting as a potential intervention tool.

The aim of this longitudinal three-wave study was to examine (i) reciprocal associations among job demands, work-related perseverative cognition (PC), and sleep quality; (ii) PC as a mediator in-between job demands and sleep quality; and (iii) continuous high job demands in relation to sleep quality and work-related PC over time. A representative sample of the Swedish working population was approached in 2010, 2012, and 2014, and 2316 respondents were included in this longitudinal full-panel survey study. Structural equation modelling was performed to analyse the temporal relations between job demands, work-related PC, and sleep quality. Additionally, a subsample (N = 1149) consisting of individuals who reported the same level of exposure to job demands during all three waves (i.e. stable high, stable moderate, or stable low job demands) was examined in relation to PC and sleep quality over time. Analyses showed that job demands, PC, and poor sleep quality were positively and reciprocally related. Work-related PC mediated the normal and reversed, direct across-wave relations between job demands and sleep quality. Individuals with continuous high job demands reported significantly lower sleep quality and higher work-related PC, compared to individuals with continuous moderate/low job demands. This study substantiated reciprocal relations between job demands, work-related PC, and sleep quality and supported work-related PC as an underlying mechanism of the reciprocal job demands-sleep relationship. Moreover, this study showed that chronically high job demands are a risk factor for low sleep quality.

Relative age-related participation and dropout trends in German youth sports clubs.

Relative age describes a youth's age within their age group cohort. Compared to relatively younger peers, relatively older youth in an annual age group cohort have been found more likely to be selected to sports teams, and to receive higher grades in education. This study examined the influence of youth sport participants' relative age on participation and dropout. Using data from the 1995 German Youth Sport Survey (N total=2612), comparisons (stratified by gender and sport type) were made between the relative age of current and former participants. Analyses also considered the type of school youths were enrolled in while exploring the influence of relative age on sport participations. No relative age effects for dropout emerged among males in team or individual sport contexts. Female dropouts were more likely to be relatively older (Q1, OR adjusted: 0.52, 95% CI: 0.34-0.80; Q2, OR adjusted: 0.55, 95% CI: 0.36-0.84; Q3, OR adjusted: 0.59, 95% CI: 0.39-0.89), an effect that was mirrored among 'artistic' sport participants. Boys and girls in schools that were for children of higher academic proficiency were more likely to be currently participating in sport. Findings suggest that relative age-related dropout effects may be context sensitive and different for males and females. For the most part, relative age did not appear to have any relationship with dropout in this sample, with some notable exceptions for females. Overall, factors such as the type of school youths were enrolled in appear to be a more salient influence on sport participation than relative age.

Sitting time is ubiquitous for most adults in developed countries and is most prevalent in three domains: in the workplace, during transport and during leisure time. The correlates of prolonged sitting time in workplace settings are not well understood. Therefore, the aim of this study was to examine the gender-specific associations between the socio-demographic, behavioural and cognitive correlates of work-related sitting time. A cross-sectional sample of working German adults (n = 1515; 747 men; 43.5 ± 11.0 years) completed questionnaires regarding domain-specific sitting times and physical activity (PA) and answered statements concerning beliefs about sitting. To identify gender-specific correlates of work-related sitting time, we used a series of linear regressions. The overall median was 2 hours of work-related sitting time/day. Regression analyses showed for men (β = -.43) and for women (β = -.32) that work-related PA was negatively associated with work-related sitting time, but leisure-related PA was not a significant correlate. For women only, transport-related PA (β = -.07) was a negative correlate of work-related sitting time, suggesting increased sitting times during work with decreased PA in transport. Education and income levels were positively associated, and in women only, age (β = -.14) had a negative correlation with work-related sitting time. For both genders, TV-related sitting time was negatively associated with work-related sitting time. The only association with cognitive correlates was found in men for the belief 'Sitting for long periods does not matter to me' (β = .10) expressing a more positive attitude towards sitting with increasing sitting durations. The present findings show that in particular, higher educated men and women as well as young women are high-risk groups to target for reducing prolonged work-related sitting time. In addition, our findings propose considering increasing transport-related PA, especially in women, as well as promoting recreation-related PA in conjunction with efforts to reduce long work-related sitting times.

A trustful relationship—the importance for relatives to actively participate in the meeting with the physician

PubMed Central

2013-01-01

In previous research, no uniform picture emerged of the role of relatives in the meeting between an elderly patient and a physician. Knowledge about relatives’ experiences of the meeting between an elderly patient and a physician will help healthcare practitioners better understand the role of relatives during the meeting and how practitioners can assist relatives in assuming their supporting role more efficiently. The purpose of this study is to explore experiences of relatives of meeting with the physician in a hospital setting when an elderly patient is discharged from hospital care to home care, in order to identify aspects that may facilitate relatives in taking up their role in a more efficient manner. This descriptive and exploratory study is based on 20 interviews with relatives. The result shows that the physician's communication style influences the meeting between the relative, the elderly patient, and the physician, and that this style is the result of power and interaction. A trustful relationship during the meeting between the relative and the physician can increase the relative's feeling of confidence with the healthcare organization and treatment of the elderly patient. The relative has an important supporting role in the care for the elderly family member, both in the hospital and the home setting. It is likely that the relative's value as a resource, for both the patient and the physician, increases as the relative experiences feelings of confidence in the meeting with the physician. It is therefore of value to increase our knowledge about the conditions and circumstances facilitating and/or hampering the meeting between the relative and the physician. The result stresses the importance of encouraging relatives to participate in the meeting. Physicians need more guidance and training in communication skills, respectful demeanor, and collaboration while meeting the relatives. PMID:23694680

Impact of age-related macular degeneration in patients with glaucoma: understanding the patients' perspective.

The aim of the study is to measure the impact of age-related macular degeneration on vision-related activity limitation and preference-based status for glaucoma patients. This was a cross-sectional study. Two-hundred glaucoma patients of whom 73 had age-related macular degeneration were included in the research. Sociodemographic information, visual field parameters and visual acuity were collected. Age-related macular degeneration was scored using the Age-Related Eye Disease Study system. The Rasch-analysed Glaucoma Activity Limitation-9 and the Visual Function Questionnaire Utility Index measured vision-related activity limitation and preference-based status, respectively. Regression models determined factors predictive of vision-related activity limitation and preference-based status. Differential item functioning compared Glaucoma Activity Limitation-9 item difficulty for those with and without age-related macular degeneration. Mean age was 73.7 (±10.1) years. Lower better eye mean deviation (β: 1.42, 95% confidence interval: 1.24-1.63, P < 0.001) and age-related macular degeneration (β: 1.26 95% confidence interval: 1.10-1.44, P = 0.001) were independently associated with worse vision-related activity limitation. Worse eye visual acuity (β: 0.978, 95% confidence interval: 0.961-0.996, P = 0.018), high risk age-related macular degeneration (β: 0.981, 95% confidence interval: 0.965-0.998, P = 0.028) and severe glaucoma (β: 0.982, 95% confidence interval: 0.966-0.998, P = 0.032) were independently associated with worse preference-based status. Glaucoma patients with age-related macular degeneration found using stairs, walking on uneven ground and judging distances of foot to step/curb significantly more difficult than those without age-related macular degeneration. Vision-related activity limitation and preference-based status are negatively impacted by severe glaucoma and age-related macular degeneration. Patients with both conditions perceive increased difficulty walking safely compared with patients with glaucoma alone. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

Materialistic Cues Boosts Personal Relative Deprivation.

PubMed

Zhang, Hong; Zhang, Wen

2016-01-01

Three studies investigated whether exposure to materialistic cues would increase perceptions of personal relative deprivation and related emotional reactions. In Study 1, individuals who were surveyed in front of a luxury store reported higher levels of personal relative deprivation than those surveyed in front of an ordinary building. In Study 2, participants who viewed pictures of luxurious goods experienced greater personal relative deprivation than those viewed pictures of neutral scenes. Study 3 replicated the results from Study 2, with a larger sample size and a more refined assessment of relative deprivation. Implications of these findings for future studies on relative deprivation and materialism are discussed.

Du, Hongfei; Li, Xiaoming; Chi, Peilian; Zhao, Junfeng; Zhao, Guoxiang

2015-12-01

Self-esteem can be derived from the relationships with significant others (relational self-esteem). However, it is unclear what the importance of relational self-esteem is for mental health and whether social support from others promotes relational self-esteem. The aim of this study was to examine the relationship between relational self-esteem and a multitude of indicators of psychological well-being among children affected by HIV. We also examined how social support from others would affect relational self-esteem. Results indicated that relational self-esteem was positively associated with psychological well-being. Support from significant others rather than others predicted increased relational self-esteem. Implications and directions for future research are discussed. © The Author(s) 2014.

Relatives want more spontaneous information from staff, particularly about residents' daily lives, and there is a need for relatives to have opportunities to talk with staff under relaxed conditions. Staff behaviour and activities towards residents and relatives are a source of many feelings for relatives. Relatives' understandings of the challenges faced by staff are not communicated to staff, nor are positive or negative experiences explicitly passed on to staff.

Individual and peer group normative beliefs about relational aggression.

Studies show that children who use relational aggression process social information in unique ways; however, findings have been inconsistent and limited by methodological weaknesses. This short-term longitudinal study examined developmental changes in 245 (49% female; ages 8-13) 3rd through 8th graders' normative beliefs about relational aggression and tested the hypothesis that individual and classroom-level norms predict relational aggression 1 year later. Results showed that the transition to middle school was marked by increased approval of relational aggression, and individual norms predicted future relational aggression. Importantly, a contextual model showed that students in peer groups highly supportive of relational aggression became increasingly aggressive. Findings extend social information processing theories of relational aggression to focus on the role of peer group cognitions.

Moderating effects of perceived growth on the association between fear of cancer recurrence and health-related quality of life among adolescent and young adult cancer survivors.

We examined whether (1) fear of cancer recurrence was related to lower health-related quality of life and (2) perceived growth moderated the link between fear of recurrence and health-related quality of life. About 292 adolescent and young adult cancer survivors (diagnosed with cancer at ages 15-34) completed a cross-sectional survey. Fear of recurrence was related to poorer physical and mental health-related quality of life. The negative association between fear of recurrence and mental health-related quality of life was moderated by perceived growth. Fostering perceived growth may mitigate the adverse associations of fear of recurrence and health-related quality of life.

Intrinsic motivation and sportsmanship: mediating role of interpersonal relationships.

Núñez, Juan L; Martín-Albo, José; Navarro, José G; Sánchez, Juana M; González-Cutre, David

2009-06-01

This study analyzed the mediating role of interpersonal relations between intrinsic motivation and sportsmanship. Athletes (98 men, 97 women), ages 11 to 43 years, completed measures of intrinsic motivation toward sports, self-concept of social and family relations, and sportsmanship orientation. A structural equation model indicated that self-concept of interpersonal relations mediated the relation between intrinsic motivation and sportsmanship. Also, intrinsic motivation was directly and positively associated with self-concept of interpersonal relations, which, in turn, was positively and significantly related to sportsmanship. Variances explained by self-concept of interpersonal relations and by sportsmanship were 32 and 56%, respectively. The motivational interaction between the context of interpersonal relations and the sports context proposed in the hierarchical model of intrinsic and extrinsic motivation was discussed.

Emergent symbolic relations in speakers and nonspeakers.

Eight adults with developmental disabilities and four typically developing preschool children participated in an experiment studying emergent stimulus-stimulus relations after match-to-sample instruction. Participants were taught to match lexigrams (arbitrary graphic stimuli) to objects. Each object was functionally related to another object in the teaching set. For example, brush and comb were members of the teaching set. Most participants were able to select objects when the objects were named in pretests. Postteaching probes assessed emergent relations between spoken names and lexigrams. In addition, we included probes to detect emergent relations between related lexigrams. That is, would participants select the lexigram for comb when the experimenter displayed the lexigram for brush (without explicit teaching)? Two preschool children and five adults with developmental disabilities showed emergent relations between lexigrams and spoken words. However, only two preschool children showed the emergent lexigram to related lexigram relations.

This study reports a comparative survey of mature students undertaking pre-registration undergraduate nursing education in Australia and Scotland. The study aimed to explore comparisons between the course-related and course-related financial difficulties faced by mature students in two very different educational and funding systems. Financial stress is a predictor of both physical and mental health problems. A similar pattern of course-related problems were reported by both Australian and Scottish students with the exception that Scottish students experienced more problems with childcare and caring for elderly relatives. Course-related problems may be inherent in the nature of undergraduate nursing education although the relatively time-intensive nature of Scottish curricula may explain the childcare and elderly relatives difference. Scottish students reported higher overall financial-related problems but Australian students reported more problems with funding placements. These findings have implications for both curriculum designers and policy makers.

Uncertainty relations based on information theory for both discrete and continuous distribution functions are briefly reviewed. We extend these results to account for (differential) Rényi entropy and its related entropy power. This allows us to find a new class of information-theoretic uncertainty relations (ITURs). The potency of such uncertainty relations in quantum mechanics is illustrated with a simple two-energy-level model where they outperform both the usual Robertson–Schrödinger uncertainty relation and Shannon entropy based uncertainty relation. In the continuous case the ensuing entropy power uncertainty relations are discussed in the context of heavy tailed wave functions and Schrödinger cat states. Again,more » improvement over both the Robertson–Schrödinger uncertainty principle and Shannon ITUR is demonstrated in these cases. Further salient issues such as the proof of a generalized entropy power inequality and a geometric picture of information-theoretic uncertainty relations are also discussed.« less

[Purpose] This study compared the knowledge of and attitudes toward dementia between health-related and non-health-related students. [Subjects] The subjects consisted of a total of 416 people, 213 health-related students and 203 non-health-related students, at K University, which is located in Gyeongsangbuk-do, Republic of Korea, between May 1 and 14, 2014. [Methods] The subjects answered a self-administered questionnaire about their knowledge of and attitudes toward dementia. [Results] There was a significant difference in knowledge of and attitudes toward dementia between the two groups examined. [Conclusion] Health-related students displayed higher knowledge of dementia and a more positive attitude toward dementia compared with non-health-related students. In the future, education to cultivate professional knowledge about dementia and enhance positive attitudes toward dementia should be provided continuously to health-related students. This is because students in health-related fields will likely provide services to patients with dementia in the clinical field. Additionally, as they will likely provide support to the elderly in the future, non-health-related students also need to be educated about and develop positive attitudes toward dementia.

2015-01-01

Through a sample of 686 Chinese adolescents (mean age = 13.73 years; 50% girls), we examined the compensatory and moderating effects of prosocial behavior on the direct and indirect associations between forms of aggression and relational victimization mediated by peer relationships among adolescent girls and boys. The results indicated that only adolescent girls’ relationally aggressive behaviors could be directly linked with their experiences of relational victimization, and both relationally and overtly aggressive adolescent boys and girls might be more often rejected by their peers, which, in turn, could make them targets of relational aggression. Next, we found that prosocial behavior indirectly counteracts the effects of aggression on relational victimization through reducing adolescents’ peer rejection and promoting adolescents’ peer attachment. In addition, relationally aggressive girls with high levels of prosocial behavior might be less rejected by peers; however, they might also have lower levels of peer attachment and be more likely to experience relational victimization. Last, adolescent boys scored higher on risks, but lower on the protective factors of relational victimization than girls, which, to some degree, might explain the gender difference in relational victimization. Finally, we discussed the theoretical and practical implications of these findings. PMID:26347704

Relative attitude dynamics and control for a satellite inspection mission

The problem of conducting an inspection mission from a chaser satellite orbiting a target spaceraft is considered. It is assumed that both satellites follow nearly circular orbits. The relative orbital motion is described by the Hill-Clohessy-Wiltshire equation. In the case of an elliptic relative orbit, it is shown that an inspection mission is feasible when the chaser is inertially pointing, provided that the camera mounted on the chaser satellite has sufficiently large field of view. The same possibility is shown when the optical axis of the chaser's camera points in, or opposite to, the tangential direction of the local vertical local horizontal frame. For an arbitrary relative orbit and arbitrary initial conditions, the concept of relative Euler angles is defined for this inspection mission. The expression of the desired relative angular velocity vector is derived as a function of Cartesian coordinates of the relative orbit. A quaternion feedback controller is then designed and shown to perform relative attitude control with admissible internal torques. Three different types of relative orbits are considered, namely the elliptic, Pogo and drifting relative orbits. Measurements of the relative orbital motion are assumed to be available from optical navigation.

The Impact of Relative Poverty on Norwegian Adolescents’ Subjective Health: A Causal Analysis with Propensity Score Matching

PubMed Central

Elstad, Jon Ivar; Pedersen, Axel West

2012-01-01

Studies have revealed that relative poverty is associated with ill health, but the interpretations of this correlation vary. This article asks whether relative poverty among Norwegian adolescents is causally related to poor subjective health, i.e., self-reported somatic and mental symptoms. Data consist of interview responses from a sample of adolescents (N = 510) and their parents, combined with register data on the family’s economic situation. Relatively poor adolescents had significantly worse subjective health than non-poor adolescents. Relatively poor adolescents also experienced many other social disadvantages, such as parental unemployment and parental ill health. Comparisons between the relatively poor and the non-poor adolescents, using propensity score matching, indicated a negative impact of relative poverty on the subjective health among those adolescents who lived in families with relatively few economic resources. The results suggest that there is a causal component in the association between relative poverty and the symptom burden of disadvantaged adolescents. Relative poverty is only one of many determinants of adolescents’ subjective health, but its role should be acknowledged when policies for promoting adolescent health are designed. PMID:23249858

2017-01-01

Purpose This study examined the relationship between headache-specific locus of control (HSLC) and migraine-related quality of life, and anxiety as a mediator of this relationship. Methods Two hundred and thirty-two people with severe migraine participated in the Treatment of Severe Migraine trial. At baseline, participants completed self-report questionnaires of headache-specific locus of control (HSLC; subscales = Internal, Chance, and Medical Professionals), anxiety, and migraine-related quality of life. Correlations examined relationships between HSLC, anxiety, and migraine-related quality of life; ordinary least squares regression evaluated anxiety as a mediator of the relationship between HSLC and migraine-related quality of life. Results Higher internal HSLC was related to higher overall migraine-related quality of life (ps < .05) and emotion function impairments (p = .012). Anxiety mediated the relationship between internal HSLC and all measures of migraine-specific quality of life (ps < .05). Higher external (medical professionals and chance) HSLC was related to higher migraine-related quality of life impairments (all ps < .001). Conclusions All HSLC beliefs are associated with higher migraine-related quality of life impairments. Anxiety mediates the relationship between internal HSLC and migraine-related quality of life.

Regulatory behavior and frontal activity: Considering the role of revised-BIS in relative right frontal asymmetry.

PubMed

Gable, Philip A; Neal, Lauren B; Threadgill, A Hunter

2018-01-01

Essential to human behavior are three core personality systems: approach, avoidance, and a regulatory system governing the two motivational systems. Decades of research has linked approach motivation with greater relative left frontal-cortical asymmetry. Other research has linked avoidance motivation with greater relative right frontal-cortical asymmetry. However, past work linking withdrawal motivation with greater relative right frontal asymmetry has been mixed. The current article reviews evidence suggesting that activation of the regulatory system (revised Behavioral Inhibition System [r-BIS]) may be more strongly related to greater relative right frontal asymmetry than withdrawal motivation. Specifically, research suggests that greater activation of the r-BIS is associated with greater relative right frontal activity, and reduced r-BIS activation is associated with reduced right frontal activity (greater relative left frontal activity). We review evidence examining trait and state frontal activity using EEG, source localization, lesion studies, neuronal stimulation, and fMRI supporting the idea that r-BIS may be the core personality system related to greater relative right frontal activity. In addition, the current review seeks to disentangle avoidance motivation and r-BIS as substrates of relative right frontal asymmetry. © 2017 Society for Psychophysiological Research.

The present study examined Japanese university students' processing time for English subject and object relative clauses in relation to their English listening proficiency. In Analysis 1, the relation between English listening proficiency and reading span test scores was analyzed. The results showed that the high and low listening comprehension groups' reading span test scores do not differ. Analysis 2 investigated English listening proficiency and processing time for sentences with subject and object relative clauses. The results showed that reading the relative clause ending and the main verb section of a sentence with an object relative clause (such as "attacked" and "admitted" in the sentence "The reporter that the senator attacked admitted the error") takes less time for learners with high English listening scores than for learners with low English listening scores. In Analysis 3, English listening proficiency and comprehension accuracy for sentences with subject and object relative clauses were examined. The results showed no significant difference in comprehension accuracy between the high and low listening-comprehension groups. These results indicate that processing time for English relative clauses is related to the cognitive processes involved in listening comprehension, which requires immediate processing of syntactically complex audio information.

Background and Objectives Cannabis is the most widely used illicit substance among young adults. Anxiety sensitivity (AS; i.e., fear of anxiety-related symptoms) is positively related to coping motives for cannabis use (which are robustly positively linked to cannabis-related problems). However, AS is unrelated to cannabis use-related problems. Yet, extant studies have been conducted on primarily White samples. It may be that among Black students, AS-physical concerns (i.e., fear of physical anxiety-related sensations) are related to cannabis problems given that Black individuals are more likely than White individuals to report experiencing greater and more intense somatic symptoms when experiencing anxiety. Black individuals may rely on cannabis to cope with fear of these somatic symptoms, continuing to use despite cannabis-related problems. Methods The current study tested whether race moderated the relation between AS-physical concerns and cannabis problems among 102 (85.3% female) current cannabis using undergraduates who were either non-Hispanic Black (n= 51) or non-Hispanic White (n= 51). Results After controlling for frequency of cannabis use, income, and gender, race significantly moderated the relation between AS-physical concerns and cannabis use-related problems such that AS-physical concerns significantly predicted cannabis-related problems among Black and not White individuals. Discussion and Conclusions Findings highlight the importance of considering race in identifying psychosocial predictors of cannabis-related problems. Scientific Significance Intervention strategies for Black cannabis users may benefit from examining and targeting AS-physical concerns. PMID:28295843

We explored relationships among black bullhead (Ameiurus melas) population characteristics and physicochemical attributes in shallow lakes and quantified relationships between population characteristics of black bullhead and sport fishes. Lake characteristics and fisheries survey data were collected from the Sandhills region of northcentral Nebraska from May through June, 1998 and 1999. Relative abundance of black bullheads was inversely related to proportional stock density (r=-0.672, df=15, P=0.004); however, neither relative weight nor growth was significantly (P ??? 0.20) related to black bullhead relative abundance. Population characteristics of common panfish species such as bluegill (Lepomis macrochirus), green sunfish (L. cyanellus), pumpkinseed (L. gibbosus), and yellow perch (Perca flavescens) were not correlated with black bullhead relative abundance or size structure. Rather, proportional stock density (r=0.655, df=10, P=0.029) and growth (r=0.59, df=11, P=0.04) of black bullhead were positively related to relative abundance of largemouth bass (Micropterus salmoides). Similarly, black bullhead relative abundance was inversely related to largemouth bass size structure (r=-0.51, df=14, P= 0.05). Black bullhead mean length at age 3 was positively related to total phosphorous concentration (r=0.65, df=16, P=0.004), and bullhead relative abundance was positively related to shoreline development index (r=0.46, df=22, P=0.03). Population characteristics of black bullhead appeared to have little influence on panfish communities. Rather, black bullhead abundance, predator density, and lake productivity exhibited stronger relationships with black bullhead population characteristics.

Generalized Kramers-Kronig relations in nonlinear optical- and THz-spectroscopy

2009-05-01

Kramers-Kronig (K-K) relations have constituted one of the principal tools in the optical spectroscopy for the assessment of the optical properties of media from measured spectra. The underlying principle for the existence of the K-K relations is causality. Thanks to the K-K relations we have achieved a better understanding of both macroscopic and microscopic properties of media. Recently, various kinds of modified K-K relations have been presented in the literature. Such relations have been applied, e.g. to the nonlinear optical properties of polymers. A typical advantage of these generalized K-K relations is that the measured data do not need to be manipulated as in the case of the traditional K-K relations. Hence, the accuracy of the inverted data on linear or nonlinear optical properties of media becomes higher. A novel way to utilize generalized K-K relations is related to the measurement and correction of terahertz spectra in the time-domain reflection spectroscopy. Terahertz spectroscopy is nowadays one of the most rapidly developing fields in modern physics with applications being related to, e.g. security at the airports or inspection of pharmaceutical tablets. While recording THz spectra it is also possible to perform a chemical mapping of species. Therefore, correctness of the spectrum is of crucial importance for the identification of different species. This is possible by the generalized K-K relations. In this review paper we consider advances of K-K relations both in nonlinear optical and THz spectroscopy.

The aim of the current paper is to examine the impact of the enactment of constitutional prohibition in the United States in 1920 on total homicides, alcohol-related homicides and non-alcohol-related homicides in Chicago. Data are drawn from the Chicago Historical Homicide Project, a data set chronicling 11 018 homicides in Chicago between 1870 and 1930. Interrupted time-series and autoregression integrated moving average (ARIMA) models are employed to examine the impact of prohibition on three separate population-adjusted homicide series. All models control for potential confounding from World War I demobilization and from trend data drawn from Wesley Skogan's Time-Series Data from Chicago. Total and non-alcohol-related homicide rates increased during prohibition by 21% and 11%, respectively, while alcohol-related homicides remained unchanged. For other covariates, alcohol-related homicides were related negatively to the size of the Chicago police force and positively to police expenditures and to the proportion of the Chicago population aged 21 years and younger. Non-alcohol-related homicides were related positively to police expenditures and negatively to the size of the Chicago police force. While total and non-alcohol-related homicides in the United States continued to rise during prohibition, a finding consistent with other studies, the rate of alcohol-related homicides remained unchanged. The divergent impact of prohibition on alcohol- and non-alcohol-related homicides is discussed in relation to previous studies of homicide in this era.

To examine the relationship between physicians' tobacco-related medical training and physicians' confidence in their tobacco-related skills and smoking-related interventions with parents of child patients. Mailed survey. Canada. The survey was mailed to 800 family physicians and 800 pediatricians across Canada, with a corrected response rate of 65% (N = 900). Physicians' self-reported tobacco-related education, knowledge, and skills, as well as smoking-related interventions with parents of child patients. Cochran-Mantel-Haenszel chi(2) tests were used to examine relationships between variables, controlling for tobacco-control involvement and physician specialty. Data analysis was conducted in 2008. Physicians reporting tobacco-related medical education were more likely to report being "very confident" in advising parents about the effects of smoking and the use of a variety of cessation strategies (P < .05). Furthermore, physicians with tobacco-related training were more likely to help parents of child patients quit smoking whether or not the children had respiratory problems (P < .05). Physicians with continuing medical education in this area were more likely to report confidence in their tobacco-related skills and to practise more smoking-related interventions than physicians with other forms of training. There is a strong relationship between medical education and physicians' confidence and practices in protecting children from secondhand smoke. Physicians with continuing medical education training are more confident in their tobacco-related skills and are more likely to practise smoking-related interventions than physicians with other tobacco-related training.

This longitudinal study examined normative beliefs about aggression (e.g., face-to-face, cyber) in relation to the engagement in cyber aggression 6 months later among 126 (69 women) young adults. Participants completed electronically administered measures assessing their normative beliefs, face-to-face and cyber aggression at Time 1, and cyber aggression 6 months later (Time 2). We found that men reported more cyber relational and verbal aggression when compared to women. After controlling for each other, Time 1 face-to-face relational aggression was positively related to Time 2 cyber relational aggression, whereas Time 1 face-to-face verbal aggression was positively related to Time 2 cyber verbal aggression. Normative beliefs regarding cyber aggression was positively related to both forms of cyber aggression 6 months later, after controlling for normative beliefs about face-to-face aggression. Furthermore, a significant two-way interaction between Time 1 cyber relational aggression and normative beliefs about cyber relational aggression was found. Follow-up analysis showed that Time 1 cyber relational aggression was more strongly related to Time 2 cyber relational aggression when young adults held higher normative beliefs about cyber relational aggression. A similar two-way interaction was found for cyber verbal aggression such that the association between Time 1 and Time 2 cyber verbal aggression was stronger at higher levels of normative beliefs about cyber verbal aggression. Results are discussed in terms of the social cognitive and behavioral mechanisms associated with the engagement of cyber aggression. © 2013 Wiley Periodicals, Inc.

The abundance properties of nearby late-type galaxies. II. The relation between abundance distributions and surface brightness profiles

The relations between oxygen abundance and disk surface brightness (OH–SB relation) in the infrared W1 band are examined for nearby late-type galaxies. The oxygen abundances were presented in Paper I. The photometric characteristics of the disks are inferred here using photometric maps from the literature through bulge-disk decomposition. We find evidence that the OH–SB relation is not unique but depends on the galactocentric distance r (taken as a fraction of the optical radius R{sub 25}) and on the properties of a galaxy: the disk scale length h and the morphological T-type. We suggest a general, four-dimensional OH–SB relation with themore » values r, h, and T as parameters. The parametric OH–SB relation reproduces the observed data better than a simple, one-parameter relation; the deviations resulting when using our parametric relation are smaller by a factor of ∼1.4 than that of the simple relation. The influence of the parameters on the OH–SB relation varies with galactocentric distance. The influence of the T-type on the OH–SB relation is negligible at the centers of galaxies and increases with galactocentric distance. In contrast, the influence of the disk scale length on the OH–SB relation is at a maximum at the centers of galaxies and decreases with galactocentric distance, disappearing at the optical edges of galaxies. Two-dimensional relations can be used to reproduce the observed data at the optical edges of the disks and at the centers of the disks. The disk scale length should be used as a second parameter in the OH–SB relation at the center of the disk while the morphological T-type should be used as a second parameter in the relation at optical edge of the disk. The relations between oxygen abundance and disk surface brightness in the optical B and infrared K bands at the center of the disk and at optical edge of the disk are also considered. The general properties of the abundance–surface brightness relations are similar for the three considered bands B, K, and W1.« less

A test of theory of planned behavior in Korea: participation in alcohol-related social gatherings.

Park, Hee Sun; Lee, Dong Wook

2009-12-01

Two studies are reported using the theory of planned behavior (TPB) to predict and explain joining and not joining alcohol-related social gatherings among Korean undergraduates in various engineering majors. Specifically, considering that the attitudinal component of TPB is behavioral-outcome-based, the current study investigated whether the outcomes of engaging in a behavior and of not engaging in a behavior would similarly predict intentions to engage in a behavior and intentions to not engage in a behavior. The current study also examined whether intentions to engage and intentions to not engage would be significantly related to self-reported behavior a week later. Participants in Study 1 reported TPB components (attitudes toward behavior, subjective norms, perceived behavioral control, and behavioral intentions) concerning joining alcohol-related social gatherings. Participants in Study 2 reported TPB components concerning not joining alcohol-related social gatherings. Additionally, a week later, the participants in both studies reported their participation in alcohol-related social gatherings from the past week. Generally, the results showed that the TPB components were significantly associated with undergraduates' intentions to join and intentions to not join. Specifically, conversation-related attitudes and senior-junior relationship-related attitudes were significantly related to intentions to join, and only group-related attitudes were significantly related to intentions to not join. Intentions to join and intentions to not join were not significantly related to self-reported behavior of joining alcohol-related social gatherings a week later. The findings from the current research provide some evidence that joining or not joining alcohol-related social gatherings may not be mere behavioral opposites, predictable by the presence or absence of the same behavioral outcomes. These two aspects of the behavior may require assessment of different behavioral outcomes or different assessments of the same behavioral outcomes.

Transplant recipients are at high risk of cytomegalovirus (CMV) infection. Mechanisms explaining the variation in risk of infections are far from fully elucidated. We hypothesised that host genetics explains part of the variation in risk of infection and examined if relatives of recipients with CMV infection have higher rates of severe infections compared to relatives of recipients without this infectious phenotype. In a register-based study, we included first-degree relatives of transplant recipients and examined the risk of hospitalisation due to overall infection or viral infection and risk of death among relatives of recipients who developed CMV infection within the first year of transplantation compared to relatives of recipients without CMV. Analyses were adjusted for sex, age and calendar year. We included 4470 relatives who were followed for 103,786 person-years, median follow-up 24 years [interquartile range (IQR) 12-36]. There were a total of 1360 infection-related hospitalisations in the follow-up period, incidence rate (IR) 13.1/1000 person-years [95% confidence interval (CI), 12.4; 13.8]. 206 relatives were hospitalised with viral infection, IR 1.8/1000 person-years (95% CI, 1.6; 2.0). There was no increased risk of hospitalisation due to infections, IR ratio (IRR) 0.99 (95% CI, 0.88; 1.12), nor specifically viral infections, IRR 0.87 (95% CI, 0.63; 1.19), in relatives of recipients with CMV compared to relatives of recipients without CMV. Also, no difference was seen in analyses stratified by transplant type, family relation and CMV serostatus. The risk of hospitalisation due to infection is not increased among first-degree relatives of transplant recipients with CMV infection compared to relatives of recipients without CMV.

The addictive nature of smoking is characterized by responses to cigarette stimuli that significantly impede smoking cessation efforts. Studies have shown that smokers are roused by appetitive smoking-related stimuli, and their consumption tends to be unaffected by the negative value of smoking. Using functional magnetic resonance imaging, the goal of this study was two-fold: to examine the brain reactivity of chronic smokers when processing the negative value of smoking using aversive smoking-related cues; to further characterize this response by comparing the latter to the processing of aversive nonsmoking-related and appetitive smoking-related cues. Thirty chronic smokers passively viewed aversive smoking-related, aversive nonsmoking-related, appetitive smoking-related and neutral images presented in a block design while being scanned. Aversive smoking-related stimuli elicited significantly greater activation in the medial prefrontal cortex, amygdala, inferior frontal gyrus and lateral orbitofrontal cortex than neutral stimuli. Aversive smoking-related stimuli elicited lower activation in the parahippocampal gyrus, insula and inferior frontal gyrus compared to the aversive nonsmoking-related condition, as well as lower activation in the posterior cingulate, precuneus and medial prefrontal cortices compared to appetitive smoking-related cues. The brain activation pattern observed suggests that chronic smokers experience an aversive response when processing aversive smoking-related stimuli, however we argue that the latter triggers a weaker negative emotional and driving response than the aversive non-smoking-related and appetitive smoking-related cues respectively. These fMRI results highlight potentially important processes underlying the insensitivity to the negative value of smoking, an important characteristic of addiction. Copyright © 2013 Elsevier Inc.

A review of the health effects of relative humidity in indoor environments suggests that relative humidity can affect the incidence of respiratory infections and allergies. Experimental studies on airborne-transmitted infectious bacteria and viruses have shown that the survival or infectivity of these organisms is minimized by exposure to relative humidities between 40 and 70%. Nine epidemiological studies examined the relationship between the number of respiratory infections or absenteeism and the relative humidity of the office, residence, or school. The incidence of absenteeism or respiratory infections was found to be lower among people working or living in environments with mid-range versus low or high relative humidities. The indoor size of allergenic mite and fungal populations is directly dependent upon the relative humidity. Mite populations are minimized when the relative humidity is below 50% and reach a maximum size at 80% relative humidity. Most species of fungi cannot grow unless the relative humidity exceeds 60%. Relative humidity also affects the rate of offgassing of formaldehyde from indoor building materials, the rate of formation of acids and salts from sulfur and nitrogen dioxide, and the rate of formation of ozone. The influence of relative humidity on the abundance of allergens, pathogens, and noxious chemicals suggests that indoor relative humidity levels should be considered as a factor of indoor air quality. The majority of adverse health effects caused by relative humidity would be minimized by maintaining indoor levels between 40 and 60%. This would require humidification during winter in areas with cold winter climates. Humidification should preferably use evaporative or steam humidifiers, as cool mist humidifiers can disseminate aerosols contaminated with allergens. PMID:3709462

Weight-related teasing has been found to be associated with low self-esteem, depressive symptoms, body dissatisfaction, and weight control behaviors in adolescents. While research has typically examined weight-related teasing directed towards the individual, little is known about weight-related teasing at the school level. This study aimed to determine the association between the school-level prevalence of weight-related teasing and psychosocial factors, body dissatisfaction and weight control behaviors in adolescents. Adolescents (N = 2,793; 53.2% female) attending 20 US public middle and high schools were surveyed as part of the Eating and Activity in Teens (EAT) 2010 study. Generalized estimating equations were used to estimate the association between school-level weight-related teasing and health variables, controlling for individual-level weight-related teasing, clustering of individuals within schools, and relevant covariates. A greater school-level prevalence of weight-related teasing was associated with lower self-esteem and greater body fat dissatisfaction in girls, and greater depressive symptoms in boys, over and above individual-level weight-related teasing. Dieting was associated with the school-level prevalence of weight-related teasing in analysis adjusted for covariates in girls, but not following adjustment for individual-level weight-related teasing. Unhealthy weight control behaviors, extreme weight control behaviors, and muscle-enhancing behaviors were not associated with the school-level prevalence of weight-related teasing in girls or boys. Findings from the current study, in conjunction with previous findings showing associations between weight-related teasing, psychological concerns, and weight control behaviors, highlight the importance of implementing strategies to decrease weight-related teasing in schools.

Health-related quality of life has been related to physical activity, sedentary behavior, and sleep among children from developed nations. These relationships have rarely been assessed in developing nations, nor have behaviors been considered in their true context, as mutually exclusive and exhaustive parts of the movement behavior composition. This study aimed to explore whether children's health-related quality of life is related to their movement behavior composition and if the relationship differs according to human development index. Children aged 9-11 years (n = 5855), from the 12-nation cross-sectional observational International Study of Childhood Obesity, Lifestyle and the Environment 2011-2013, self-reported their health-related quality of life (KIDSCREEN-10). Daily movement behaviors were from 24-h, 7-day accelerometry. Isometric log-ratio mixed-effect linear models were used to calculate estimates for difference in health-related quality of life for the reallocation of time between daily movement behaviors. Children from countries of higher human development index reported stronger positive relationships between health-related quality of life and moderate-to-vigorous physical activity, relative to the remaining behaviors (r = 0.75, p = 0.005) than those from lower human development index countries. In the very high human development index strata alone, health-related quality of life was significantly related to the movement behavior composition (p = 0.005), with moderate-to-vigorous physical activity (relative to remaining behaviors) being positively associated with health-related quality of life. The relationship between children's health-related quality of life and their movement behaviors is moderated by their country's human development index. This should be considered when 24-h movement behavior guidelines are developed for children around the world.

Background Work examining the link between lower heart rate variability (HRV) and depression in children and adolescents is lacking, especially in light of the physiological changes that occur during pubertal development. Method We investigated the association between spectral measures of resting HRV and depressive symptoms among 127 children and adolescents, ages 10–17. Using spectral analysis, we evaluated (1) the association between relative high frequency (HF) HRV and depressive symptoms; (2) the predictive power of relative HF HRV for depressive symptoms in the context of relative low frequency (LF) and relative very low frequency (VLF) HRV; and (3) the relationship between relative HF, LF, and VLF band activity, age and pubertal maturation. Results Consistent with previous work, results revealed that relative HF HRV was negatively associated with self-reported depressive symptoms. As well, relative VLF HRV was positively associated with depressive symptoms. Regression analyses revealed that relative HF HRV and relative VLF HRV significantly predicted self-report depressive symptoms while controlling for age, sex and pubertal maturation, with relative VLF HRV emerging as the strongest indicator of depressive symptoms. Developmental findings also emerged. Age and pubertal maturation were negatively associated with relative HF HRV and positively correlated with relative VLF HRV. Conclusions Results provide support for the relationship between HRV and depression and suggest that both HF and VLF HRV are relevant to depression symptom severity. Findings also reinforce the importance of considering pubertal development when investigating HRV-depression associations in children and adolescents. Limitations Influences on cardiac control including physical activity levels and exercise patterns could be controlled in future work. Our data speak to a depressive symptom dimension and relative spectral power HRV. Thus, we cannot make strong claims about relative spectral power HRV and clinical depression. PMID:26233322

Substance use disorders are major contributors to excess mortality among individuals with attention deficit hyperactivity disorder (ADHD), yet associations between pharmacological ADHD treatment and substance-related problems remain unclear. This study investigated concurrent and long-term associations between ADHD medication treatment and substance-related events. The authors analyzed 2005-2014 commercial health care claims from 2,993,887 (47.2% female) adolescent and adult ADHD patients. Within-individual analyses compared the risk of substance-related events (i.e., emergency department visits related to substance use disorders) during months in which patients received prescribed stimulant medication or atomoxetine relative to the risk during months in which they did not. In adjusted within-individual comparisons, relative to periods in which patients did not receive ADHD medication, male patients had 35% lower odds of concurrent substance-related events when receiving medication (odds ratio=0.65, 95% CI=0.64-0.67), and female patients had 31% lower odds of concurrent substance-related events (odds ratio=0.69, 95% CI=0.67-0.71). Moreover, male patients had 19% lower odds of substance-related events 2 years after medication periods (odds ratio=0.81, 95% CI=0.78-0.85), and female patients had 14% lower odds of substance-related events 2 years after medication periods (odds ratio=0.86, 95% CI= 0.82-0.91). Sensitivity analyses supported most findings but were less consistent for long-term associations among women. These results provide evidence that receiving ADHD medication is unlikely to be associated with greater risk of substance-related problems in adolescence or adulthood. Rather, medication was associated with lower concurrent risk of substance-related events and, at least among men, lower long-term risk of future substance-related events.

Two kinds of Airy-related beams are introduced in this manuscript. The normalized intensity distribution in the x-direction of the two kinds of Airy-related beams is close to that of the Gaussian beam. The normalized intensity distribution in the y-direction of the two kinds of Airy-related beams is close to that of the second-order and the third-order elegant Hermite-Gaussian beams, respectively. Analytical expressions of the two kinds of Airy-related beams passing through an ABCD paraxial optical system are derived. The beam propagation factors for the two kinds of Airy-related beams are 1.933 and 2.125, respectively. Analytical expressions of the beam half widths and the kurtosis parameters of the two kinds of Airy-related beams passing through an ABCD paraxial optical system are also presented. As a numerical example, the propagation properties of the two kinds of Airy-related beams are demonstrated in free space. Moreover, the comparison between the two kinds of Airy-related beams and their corresponding elegant Hermite-Gaussian beams along the two transverse directions are performed in detail. Upon propagation, the former kind of Airy-related beam will evolve from the central bright beam into the dark hollow beam. Contrarily, the latter kind of Airy-related beam will evolve from the dark hollow beam into the central bright beam. These two kinds of Airy-related beams can be used to describe specially distributed beams.

Background Automatic recognition of relations between a specific disease term and its relevant genes or protein terms is an important practice of bioinformatics. Considering the utility of the results of this approach, we identified prostate cancer and gene terms with the ID tags of public biomedical databases. Moreover, considering that genetics experts will use our results, we classified them based on six topics that can be used to analyze the type of prostate cancers, genes, and their relations. Methods We developed a maximum entropy-based named entity recognizer and a relation recognizer and applied them to a corpus-based approach. We collected prostate cancer-related abstracts from MEDLINE, and constructed an annotated corpus of gene and prostate cancer relations based on six topics by biologists. We used it to train the maximum entropy-based named entity recognizer and relation recognizer. Results Topic-classified relation recognition achieved 92.1% precision for the relation (an increase of 11.0% from that obtained in a baseline experiment). For all topics, the precision was between 67.6 and 88.1%. Conclusion A series of experimental results revealed two important findings: a carefully designed relation recognition system using named entity recognition can improve the performance of relation recognition, and topic-classified relation recognition can be effectively addressed through a corpus-based approach using manual annotation and machine learning techniques.

The medial temporal lobes distinguish between within-item and item-context relations during autobiographical memory retrieval.

PubMed

Sheldon, Signy; Levine, Brian

2015-12-01

During autobiographical memory retrieval, the medial temporal lobes (MTL) relate together multiple event elements, including object (within-item relations) and context (item-context relations) information, to create a cohesive memory. There is consistent support for a functional specialization within the MTL according to these relational processes, much of which comes from recognition memory experiments. In this study, we compared brain activation patterns associated with retrieving within-item relations (i.e., associating conceptual and sensory-perceptual object features) and item-context relations (i.e., spatial relations among objects) with respect to naturalistic autobiographical retrieval. We developed a novel paradigm that cued participants to retrieve information about past autobiographical events, non-episodic within-item relations, and non-episodic item-context relations with the perceptuomotor aspects of retrieval equated across these conditions. We used multivariate analysis techniques to extract common and distinct patterns of activity among these conditions within the MTL and across the whole brain, both in terms of spatial and temporal patterns of activity. The anterior MTL (perirhinal cortex and anterior hippocampus) was preferentially recruited for generating within-item relations later in retrieval whereas the posterior MTL (posterior parahippocampal cortex and posterior hippocampus) was preferentially recruited for generating item-context relations across the retrieval phase. These findings provide novel evidence for functional specialization within the MTL with respect to naturalistic memory retrieval. © 2015 Wiley Periodicals, Inc.

Does Increasing Community and Liquor Licensees’ Awareness, Police Activity, and Feedback Reduce Alcohol-Related Violent Crime? A Benefit-Cost Analysis

Approximately half of all alcohol-related crime is violent crime associated with heavy episodic drinking. Multi-component interventions are highly acceptable to communities and may be effective in reducing alcohol-related crime generally, but their impact on alcohol-related violent crime has not been examined. This study evaluated the impact and benefit-cost of a multi-component intervention (increasing community and liquor licensees’ awareness, police activity, and feedback) on crimes typically associated with alcohol-related violence. The intervention was tailored to weekends identified as historically problematic in 10 experimental communities in NSW, Australia, relative to 10 control ones. There was no effect on alcohol-related assaults and a small, but statistically significant and cost-beneficial, effect on alcohol-related sexual assaults: a 64% reduction in in the experimental relative to control communities, equivalent to five fewer alcohol-related sexual assaults, with a net social benefit estimated as AUD$3,938,218. The positive benefit-cost ratio was primarily a function of the value that communities placed on reducing alcohol-related harm: the intervention would need to be more than twice as effective for its economic benefits to be comparable to its costs. It is most likely that greater reductions in crimes associated with alcohol-related violence would be achieved by a combination of complementary legislative and community-based interventions.

Attributional Style and Depression in Multiple Sclerosis

Arnett, Peter A.

2013-01-01

Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.

Energy is emerging as a topic of importance to organizations, yet we have little understanding of how energy can be useful at an interpersonal level toward achieving workplace goals. We present the results of 4 studies aimed at developing, validating, and testing the relational energy construct. In Study 1, we report qualitative insights from 64 individuals about the experience and functioning of relational energy in the workplace. Study 2 draws from 3 employee samples to conduct exploratory and confirmatory factor analyses on a measure of relational energy, differentiating relational energy from related constructs. To test the predictive validity of the new relational energy scale, Study 3 comprises data from employees rating the level of relational energy they experienced during interactions with their leaders in a health services context. Results showed that relational energy employees experienced with their leaders at Time 1 predicted job engagement at Time 2 (1 month later), while controlling for the competing construct of perceived social support. Study 4 shows further differentiation of relational energy from leader-member exchange (LMX), replicates the positive relationship between relational energy (Time 1) and job engagement (Time 2), and shows that relational energy is positively associated with employee job performance (Time 3) through the mechanism of job engagement. We discuss the theoretical implications of our findings and highlight areas for future research. (c) 2016 APA, all rights reserved).

Emotionally salient information is well attended and remembered. It has been shown that infatuated individuals have increased attention for their beloved. It is unknown whether this attention bias generalizes to information related to the beloved. Moreover, infatuated individuals report to remember trivial things about their beloved, but this has not yet been tested empirically. In two studies, we tested whether infatuated individuals have increased attention and memory for beloved-related information. In a passive viewing task (Study 1), the late positive potential, an event-related potential (ERP) component reflecting motivated attention, was enhanced for beloved-related vs friend-related words/phrases. In a recognition task (Study 2), memory performance and the frontal and parietal ERP old/new effects, reflecting familiarity and recollection, respectively, were not enhanced for beloved-related compared with friend-related words/phrases. In free recall tasks in both studies, memory was better for beloved-related than friend-related words/phrases. This research reveals that attention and memory are enhanced for beloved-related information. These attention and memory biases for beloved-related information were not due to valence, semantic relatedness, or experience, but to arousal. To conclude, romantic love has profound effects on cognition that play a clear role in daily life. © The Author (2014). Published by Oxford University Press.

Currently there is a trend towards less or no use of sedation of mechanically ventilated patients. Still, little is known about how different sedation strategies affect relatives' satisfaction with the Intensive Care Unit (ICU). To explore if there was a difference in relatives' personal reactions and the degree of satisfaction with information, communication, surroundings, care and treatment in the ICU between relatives of patients who receive no sedation compared with relatives of patients receiving sedation during mechanical ventilation in the ICU. A survey study using a questionnaire with 39 questions was distributed to relatives of mechanically ventilated patients, who had been randomised to either sedation with daily wake up or no sedation. Forty-nine questionnaires were sent out and 36 relatives answered. The response rate was 73%. We found no differences in relatives' personal reactions or in the degree of satisfaction with information, communication, care and treatment in the ICU between relatives of patients in the two groups. Relatives of patients treated with no sedation felt more bothered by disturbances in the surroundings compared with relatives of patients who were sedated (p=0.03). Treating the patient during mechanical ventilation with no sedation does not affect relatives' satisfaction adversely. Copyright © 2016 Elsevier Ltd. All rights reserved.

Relative Deprivation and Relative Wealth Enhances Anti-Immigrant Sentiments: The V-Curve Re-Examined

PubMed Central

Jetten, Jolanda; Mols, Frank; Postmes, Tom

2015-01-01

Previous research has shown that negative attitudes towards immigrants and support for anti-immigrant parties are observed both among those experiencing relative deprivation and those experiencing relative gratification (so called v-curve). Whereas the effect of relative deprivation is intuitive, the effect of relative gratification is more difficult to explain. Why would economic prosperity provoke negative attitudes towards immigrants? We first present correlational (Study 1) and experimental (Study 2) support for the v-curve. In Study 1, in a national Swiss referendum, a higher percentage anti-immigrant voting was found in cantons with relatively lower and relatively higher relative disposable income. In Study 2, in a hypothetical society, more opposition to ‘newcomers’ joining society was found among poor or above average wealth group members than among those in a moderate wealth group condition. In Study 3, we replicate this finding and also show that opposition to immigration is higher for all wealth groups when societal inequality is growing rather than declining. In a final study, we examine different forms of relative gratification and mediators of the relationship between relative gratification and opposition to immigration (i.e., identification, collective self-definition as competent and cold, and fear about future wealth). Only fear about future wealth mediates this relationship. We conclude that, paradoxically, relative gratification effects are partly due to the fear of future deprivation. PMID:26461497

Infants learn a rule predicated on the relation same but fail to simultaneously learn a rule predicated on the relation different.

PubMed

Hochmann, Jean-Rémy; Carey, Susan; Mehler, Jacques

2018-08-01

In two experiments, we assessed whether infants are able to learn rules predicated on two abstract relations linked by negation: same and different (not same). In an anticipatory looking paradigm, the relation between successive colored geometrical shapes predicted the location where a puppet would appear next. In Experiment 1, 7-month-olds learned and generalized a rule predicated on the relation same, but not a rule predicated on the relation different. Similarly, in Experiment 2, 12-month-olds learned a rule predicated on the relation same-shape, but not a rule predicated on the relation different-shape. Comparing our data with that from previous experiments in the speech domain, we found no effect of age, modality or rule complexity. We conclude that, in the first year of life, infants already possess a representation of the abstract relation same, which serves as input to a rule. In contrast, we find no evidence that they represent the relation different. Copyright © 2018 Elsevier B.V. All rights reserved.

Facilitating relational framing in children and individuals with developmental delay using the relational completion procedure.

PubMed

Walsh, Sinead; Horgan, Jennifer; May, Richard J; Dymond, Simon; Whelan, Robert

2014-01-01

The Relational Completion Procedure is effective for establishing same, opposite and comparative derived relations in verbally able adults, but to date it has not been used to establish relational frames in young children or those with developmental delay. In Experiment 1, the Relational Completion Procedure was used with the goal of establishing two 3-member sameness networks in nine individuals with Autism Spectrum Disorder (eight with language delay). A multiple exemplar intervention was employed to facilitate derived relational responding when required. Seven of nine participants in Experiment 1 passed tests for derived relations. In Experiment 2, eight participants (all of whom, except one, had a verbal repertoire) were given training with the aim of establishing two 4-member sameness networks. Three of these participants were typically developing young children aged between 5 and 6 years old, all of whom demonstrated derived relations, as did four of the five participants with developmental delay. These data demonstrate that it is possible to reliably establish derived relations in young children and those with developmental delay using an automated procedure. © Society for the Experimental Analysis of Behavior.

Overload, and Cutbacks, and Freezes, Oh My! The Relative Effects of the Recession-Related Stressors on Employee Strain and Job Satisfaction.

PubMed

Jones, Morgan D; Sliter, Michael; Sinclair, Robert R

2016-12-01

Across the globe, economic fluctuations have taken their toll on both organizations and employees, particularly during sustained recessions. Surprisingly, little research, however, has directly investigated the effects of recessions on employees. As such, the goal of the current study was to investigate the effects of specific recession-related stressors on employee outcomes (strain and satisfaction). We investigated an archival data set of 7666 individuals collected as part of the Workplace Employment Relations Study for relations among recession-related stressors with strain and job satisfaction variables. We found that recession-related stressors were significantly related to both strain and satisfaction. More specifically, certain recession-related stressors (e.g. increased workload and reorganization of work) were more strongly related to strain and satisfaction than others. These results imply the need for greater attention to stress management strategies aimed at helping both employees and their organizations cope with the human costs of economic recessions.

Differential age-related effects on conjunctive and relational visual short-term memory binding.

PubMed

Bastin, Christine

2017-12-28

An age-related associative deficit has been described in visual short-term binding memory tasks. However, separate studies have suggested that ageing disrupts relational binding (to associate distinct items or item and context) more than conjunctive binding (to integrate features within an object). The current study directly compared relational and conjunctive binding with a short-term memory task for object-colour associations in 30 young and 30 older adults. Participants studied a number of object-colour associations corresponding to their individual object span level in a relational task in which objects were associated to colour patches and a conjunctive task where colour was integrated into the object. Memory for individual items and for associations was tested with a recognition memory test. Evidence for an age-related associative deficit was observed in the relational binding task, but not in the conjunctive binding task. This differential impact of ageing on relational and conjunctive short-term binding is discussed by reference to two underlying age-related cognitive difficulties: diminished hippocampally dependent binding and attentional resources.

The role of body-related self-conscious emotions in motivating women's physical activity.

PubMed

Sabiston, Catherine M; Brunet, Jennifer; Kowalski, Kent C; Wilson, Philip M; Mack, Diane E; Crocker, Peter R E

2010-08-01

The purpose of this study was to test a model where body-related self-conscious emotions of shame, guilt, and pride were associated with physical activity regulations and behavior. Adult women (N = 389; M age = 29.82, SD = 15.20 years) completed a questionnaire assessing body-related pride, shame, and guilt, motivational regulations, and leisure-time physical activity. The hypothesized measurement and structural models were deemed adequate, as was a revised model examining shame-free guilt and guilt-free shame. In the revised structural model, body-related pride was positively significantly related to identified and intrinsic regulations. Body-related shame-free guilt was significantly associated with external, introjected, and identified regulations. Body-related guilt-free shame was significantly positively related to external and introjected regulation, and negatively associated with intrinsic regulation. Identified and intrinsic regulations were significantly positively related to physical activity (R2 = .62). These findings highlight the importance of targeting and understanding the realm of body-related self-conscious emotions and the associated links to regulations and physical activity behavior.

Emergent Stimulus Relations Depend on Stimulus Correlation and Not on Reinforcement Contingencies

PubMed Central

Minster, Sara Tepaeru; Elliffe, Douglas; Muthukumaraswamy, Suresh D

2011-01-01

We aimed to investigate whether novel stimulus relations would emerge from stimulus correlations when those relations explicitly conflicted with reinforced relations. In a symbolic matching-to-sample task using kanji characters as stimuli, we arranged class-specific incorrect comparison stimuli in each of three classes. After presenting either Ax or Cx stimuli as samples, choices of Bx were reinforced and choices of Gx or Hx were not. Tests for symmetry, and combined symmetry and transitivity, showed the emergence of three 3-member (AxBxCx) stimulus classes in 5 of 5 human participants. Subsequent tests for all possible emergent relations between Ax, Bx, Cx and the class-specific incorrect comparisons Gx and Hx showed that these relations emerged for 4 of 5 the participants after extended overtraining of the baseline relations. These emergent relations must have been based on stimulus–stimulus correlations, and were not properties of the trained discriminated operants, because they required control by relations explicitly extinguished during training. This result supports theoretical accounts of emergent relations that emphasize stimulus correlation over operant contingencies. PMID:21547070

Robust adaptive relative position and attitude control for spacecraft autonomous proximity.

PubMed

Sun, Liang; Huo, Wei; Jiao, Zongxia

2016-07-01

This paper provides new results of the dynamical modeling and controller designing for autonomous close proximity phase during rendezvous and docking in the presence of kinematic couplings and model uncertainties. A globally defined relative motion mechanical model for close proximity operations is introduced firstly. Then, in spite of the kinematic couplings and thrust misalignment between relative rotation and relative translation, robust adaptive relative position and relative attitude controllers are designed successively. Finally, stability of the overall system is proved that the relative position and relative attitude are uniformly ultimately bounded, and the size of the ultimate bound can be regulated small enough by control system parameters. Performance of the controlled overall system is demonstrated via a representative numerical example. Copyright © 2016 ISA. Published by Elsevier Ltd. All rights reserved.

Knowledge-rich temporal relation identification and classification in clinical notes

PubMed Central

D’Souza, Jennifer; Ng, Vincent

2014-01-01

Motivation: We examine the task of temporal relation classification for the clinical domain. Our approach to this task departs from existing ones in that it is (i) ‘knowledge-rich’, employing sophisticated knowledge derived from discourse relations as well as both domain-independent and domain-dependent semantic relations, and (ii) ‘hybrid’, combining the strengths of rule-based and learning-based approaches. Evaluation results on the i2b2 Clinical Temporal Relations Challenge corpus show that our approach yields a 17–24% and 8–14% relative reduction in error over a state-of-the-art learning-based baseline system when gold-standard and automatically identified temporal relations are used, respectively.

State-independent uncertainty relations and entanglement detection

NASA Astrophysics Data System (ADS)

Qian, Chen; Li, Jun-Li; Qiao, Cong-Feng

2018-04-01

The uncertainty relation is one of the key ingredients of quantum theory. Despite the great efforts devoted to this subject, most of the variance-based uncertainty relations are state-dependent and suffering from the triviality problem of zero lower bounds. Here we develop a method to get uncertainty relations with state-independent lower bounds. The method works by exploring the eigenvalues of a Hermitian matrix composed by Bloch vectors of incompatible observables and is applicable for both pure and mixed states and for arbitrary number of N-dimensional observables. The uncertainty relation for the incompatible observables can be explained by geometric relations related to the parallel postulate and the inequalities in Horn's conjecture on Hermitian matrix sum. Practical entanglement criteria are also presented based on the derived uncertainty relations.

The effects of anxiety and depression on stress-related growth among Chinese army recruits: Resilience and coping as mediators.

PubMed

2016-09-01

Stress-related growth can occur after various traumas or stressful events. In order to investigate how anxiety and depression relate to stress-related growth, this study was conducted with 443 Chinese army recruits who had just finished a 3-month recruit training program. Path analyses revealed that resilience and positive/negative coping partially mediated the effect of anxiety on perceived stress-related growth, while negative coping fully mediated the relationship between depression and perceived stress-related growth. Moreover, positive coping partially carried the influence of resilience on perceived stress-related growth. Anxiety and depression may be potential targets for intervention to enhance the development of stress-related growth among Chinese army recruits. © The Author(s) 2015.

[Work-related medical rehabilitation for patients with rheumatic diseases].

PubMed

Ehlebracht-König, I; Dorn, M

2014-02-01

In recent years work-related rehabilitation has been intensified. Several studies have shown the effectiveness of work-related interventions in medical rehabilitation by improving participation in the work force and reducing sick leave. The German pension insurance fund has developed standardized requirements for medical work-related rehabilitation which include diagnostic procedures to identify patients with specific occupational problems and vocation-related interventions. These requirements address patients across different indications and diagnoses. Rehabilitation centers are assigned to different levels of work-related interventions depending on the intensity and specificity of the profile. Centers providing the complete range of work-related interventions offer differentiated work-related diagnostics, job training and occupational groups in addition to general social advice. In this article four case studies with different priorities regarding vocational interventions are presented.

Relatives' information needs and the characteristics of their search for information--in the words of relatives of stroke survivors.

Wallengren, Catarina; Segesten, Kerstin; Friberg, Febe

To explore relatives' information needs and the characteristics of their information-seeking process shortly after the stroke event and six months later. Providing relatives of stroke survivors with information is important, as lack of information increases their uncertainty and risk becoming the 'second patient in the family' and early death. Therefore, it is essential to be aware of relatives' information needs and information-seeking process the first six months after stroke. This qualitative study has a descriptive design. Open-ended interviews were conducted with sixteen relatives after stroke survivor's admission to stroke unit and six months later with nine of these relatives. Data were analysed by means of content analysis. The identified information needs covered the spectrum from stroke survivor's medical condition because nurses' actions to relatives' changed health and life situation. Furthermore, relatives' information-seeking process was found to be related to their level of personal involvement, situational circumstances, different forms of knowledge and sources of information. Relatives' search for information emerges when health and lifestyle changes occur in survivors or themselves. It is important that this information affect them personally. Also, they need to develop different forms of knowledge when they cannot trust their own competences. As a result, instead of following established curricula based on their beliefs of relatives' information needs, nurses need to practice on identifying relatives' information needs. Different information needs and characteristics described in the study can serve as guidance in the development and implementation of pedagogical interventions to support relatives of stroke survivors. One pedagogical implication is to explore what a specific relative wants to know by how he/she talks or thinks about it. Thus, it must be taken into consideration that level of personal involvement, situational circumstances, sources of information and factual knowledge, understanding and skills are intertwined. © 2010 Blackwell Publishing Ltd.

Apolipoprotein E-epsilon 4 allele and familial risk in Alzheimer's disease.

Recent studies have found an association between presence of apolipoprotein E (APOE) epsilon 4 allele and Alzheimer's disease (AD). The present study compared the cumulative risk of primary progressive dementia (PPD) in relatives of AD probands carrying at least one copy of the epsilon 4 allele with the relatives of AD probands not carrying epsilon 4 and with relatives of non-demented controls. Our aim was to determine whether the familial aggregation of PPD in relatives of AD probands is primarily due to those carrying epsilon 4. Seventy-seven neuropathologically diagnosed AD patients were obtained as probands through our Alzheimer's Disease Research Center Brain Bank. AD probands were genotyped for APOE. As a comparison group, 198 non-demented probands were also included. Through family informants, demographic and diagnostic data were collected on 382 first-degree relatives (age > or = 45 years) of AD probands and 848 relatives of the controls. We found that the cumulative risk of PPD in both relatives of AD probands with and without the epsilon 4 allele was significantly higher than that in the relatives of non-demented controls. However, the increased risk in the relatives of AD probands with the epsilon 4 allele was marginally, but not significantly, lower than the risk in the relatives of probands without epsilon 4. A greater likelihood of death by heart diseases over developing PPD in relatives of AD probands with epsilon 4 (3.1-fold increase) was found compared to relatives of probands without epsilon 4 (1.7-fold increase), especially prior to age 70, although the difference was not statistically significant. The increased familial risk for PPD in the relatives of AD probands with the APOE-epsilon 4 allele relative to controls suggests that familial factors in addition to APOE-epsilon 4 are risk factors for AD. Differential censorship from increased mortality of heart diseases may have prevented a higher incidence of PPD among the relatives of probands with epsilon 4.

Relational health, alexithymia, and psychological distress in college women: testing a mediator model.

PubMed

Liang, Belle; West, Jennifer

2011-04-01

Relational health refers to interpersonal interactions that are growth-fostering or mutually empathic and empowering. Poor relational health increases an individual's risk for developing psychological distress. Alexithymia is the inability to recognize and express one's own internal emotional experience. In this study, the associations of relational health, psychological distress, and alexithymia were examined by surveying 197 female undergraduate psychology students. Support was found for the hypothesis that alexithymic symptoms mediate the direct effect of poor relational health on psychological distress. The importance of assessing relational health and tailoring counseling interventions for people with low relational health and alexithymic symptoms is discussed. © 2011 American Orthopsychiatric Association.

Materialistic Cues Boosts Personal Relative Deprivation

PubMed Central

Zhang, Hong; Zhang, Wen

2016-01-01

Three studies investigated whether exposure to materialistic cues would increase perceptions of personal relative deprivation and related emotional reactions. In Study 1, individuals who were surveyed in front of a luxury store reported higher levels of personal relative deprivation than those surveyed in front of an ordinary building. In Study 2, participants who viewed pictures of luxurious goods experienced greater personal relative deprivation than those viewed pictures of neutral scenes.

A review of the health effects of relative humidity in indoor environments suggests that relative humidity can affect the incidence of respiratory infections and allergies. Experimental studies on airborne-transmitted infectious bacteria and viruses have shown that the survival or infectivity of these organisms is minimized by exposure to relative humidities between 40 and 70%. Nine epidemiological studies examined the relationship between the number of respiratory infections or absenteeism and the relative humidity of the office, residence, or school. The incidence of absenteeism or respiratory infections was found to be lower among people working or living in environments with mid-range versusmore » low or high relative humidities. The indoor size of allergenic mite and fungal populations is directly dependent upon the relative humidity. Mite populations are minimized when the relative humidity is below 50% and reach a maximum size at 80% relative humidity. Most species of fungi cannot grow unless the relative humidity exceeds 60%. Relative humidity also affects the rate of offgassing of formaldehyde from indoor building materials, the rate of formation of acids and salts from sulfur and nitrogen dioxide, and the rate of formation of ozone. The influence of relative humidity on the abundance of allergens, pathogens, and noxious chemicals suggests that indoor relative humidity levels should be considered as a factor of indoor air quality. The majority of adverse health effects caused by relative humidity would be minimized by maintaining indoor levels between 40 and 60%. This would require humidification during winter in areas with cold winter climates. Humidification should preferably use evaporative or steam humidifiers, as cool mist humidifiers can disseminate aerosols contaminated with allergens.« less

'We, not them and us?' Views on the relationships and interactions between staff and relatives of older people permanently living in nursing homes This study describes relatives' and staffs' experiences of each other in their relationships and interactions in connection with the care of old people with dementia living in nursing homes. The aim was to identify obstacles and promoters concerning these interactions. A qualitative method was used. Data were collected from 27 hours of observations of group discussions about relatives' and staffs' communication, interactions and experiences. Three different groups, with eight participants, relatives, staff and a group leader in each, met six times during a period of 3 months. Findings indicate that the experiences that relatives and staff have of each other are related to issues about influence, participation, trust and measures to avoid conflicts. These conclusions build on concrete descriptions about care, activities, competence, communication and visits given by research participants. Experiences of situations were sometimes contradictory between relatives and staff. This implies that the potential for cooperation between relatives and staff in care of the elderly is not fully utilized. Suggestions for enhancing the relationships between relatives and staff are: pre-planned informal, individual conversations between relatives and staff; development of ways to give regular two-way feedback about matters concerning the resident and the relationship between staff and relatives; giving staff credit for measures taken to facilitate relatives' involvement in the nursing home care; measures to improve documentation about families' involvement; and working together with minor practical tasks.

Exploring relation types for literature-based discovery.

PubMed

Preiss, Judita; Stevenson, Mark; Gaizauskas, Robert

2015-09-01

Literature-based discovery (LBD) aims to identify "hidden knowledge" in the medical literature by: (1) analyzing documents to identify pairs of explicitly related concepts (terms), then (2) hypothesizing novel relations between pairs of unrelated concepts that are implicitly related via a shared concept to which both are explicitly related. Many LBD approaches use simple techniques to identify semantically weak relations between concepts, for example, document co-occurrence. These generate huge numbers of hypotheses, difficult for humans to assess. More complex techniques rely on linguistic analysis, for example, shallow parsing, to identify semantically stronger relations. Such approaches generate fewer hypotheses, but may miss hidden knowledge. The authors investigate this trade-off in detail, comparing techniques for identifying related concepts to discover which are most suitable for LBD. A generic LBD system that can utilize a range of relation types was developed. Experiments were carried out comparing a number of techniques for identifying relations. Two approaches were used for evaluation: replication of existing discoveries and the "time slicing" approach.(1) RESULTS: Previous LBD discoveries could be replicated using relations based either on document co-occurrence or linguistic analysis. Using relations based on linguistic analysis generated many fewer hypotheses, but a significantly greater proportion of them were candidates for hidden knowledge. The use of linguistic analysis-based relations improves accuracy of LBD without overly damaging coverage. LBD systems often generate huge numbers of hypotheses, which are infeasible to manually review. Improving their accuracy has the potential to make these systems significantly more usable. © The Author 2015.

Deceased-related thinking is central to grieving and potentially critical to processing of the loss. Self-report measurements might fail to capture important elements of deceased-related thinking and processing. Here, we used a machine learning approach applied to fMRI - known as neural decoding - to develop a measure of ongoing deceased-related processing. 23 subjects grieving the loss of a first-degree relative, spouse or partner within 14 months underwent two fMRI tasks. They first viewed pictures and stories related to the deceased, a living control and a demographic control figure while providing ongoing valence and arousal ratings. Second, they performed a 10-minute Sustained Attention to Response Task (SART) with thought probes every 25-35 seconds to identify deceased, living and self-related thoughts. A conjunction analysis, controlling for valence/arousal, identified neural clusters in basal ganglia, orbital prefrontal cortex and insula associated with both types of deceased-related stimuli vs. the two control conditions in the first task. This pattern was applied to fMRI data collected during the SART, and discriminated deceased-related but not living or self-related thoughts, independently of grief-severity and time since loss. Deceased-related thoughts on the SART correlated with self-reported avoidance. The neural model predicted avoidance over and above deceased-related thoughts. A neural pattern trained to identify mental representations of the deceased tracked deceased-related thinking during a sustained attention task and also predicted subject-level avoidance. This approach provides a new imaging tool to be used as an index of processing the deceased for future studies of complicated grief.

The relationship between relational models and individualism and collectivism: evidence from culturally diverse work groups.

PubMed

Vodosek, Markus

2009-04-01

Relational models theory (Fiske, 1991 ) proposes that all thinking about social relationships is based on four elementary mental models: communal sharing, authority ranking, equality matching, and market pricing. Triandis and his colleagues (e.g., Triandis, Kurowski, & Gelfand, 1994 ) have suggested a relationship between the constructs of horizontal and vertical individualism and collectivism and Fiske's relational models. However, no previous research has examined this proposed relationship empirically. The objective of the current study was to test the association between the two frameworks in order to further our understanding of why members of culturally diverse groups may prefer different relational models in interactions with other group members. Findings from this study support a relationship between Triandis' constructs and Fiske's four relational models and uphold Fiske's ( 1991 ) claim that the use of the relational models is culturally dependent. As hypothesized, horizontal collectivism was associated with a preference for equality matching and communal sharing, vertical individualism was related to a preference for authority ranking, and vertical collectivism was related to a preference for authority ranking and communal sharing. However, contrary to expectations, horizontal individualism was not related to a preference for equality matching and market pricing, and vertical individualism was not associated with market pricing. By showing that there is a relationship between Triandis' and Fiske's frameworks, this study closes a gap in relational models theory, namely how culture relates to people's preferences for relational models. Thus, the findings from this study will enable future researchers to explain and predict what relational models are likely to be used in a certain cultural context.

The relational luring effect: Retrieval of relational information during associative recognition.

PubMed

Popov, Vencislav; Hristova, Penka; Anders, Royce

2017-05-01

Here we argue that semantic relations (e.g., works in: nurse-hospital) have abstract independent representations in long-term memory (LTM) and that the same representation is accessed by all exemplars of a specific relation. We present evidence from 2 associative recognition experiments that uncovered a novel relational luring effect (RLE) in recognition memory. Participants studied word pairs, and then discriminated between intact (old) pairs and recombined lures. In the first experiment participants responded more slowly to lures that were relationally similar (table-cloth) to studied pairs (floor-carpet), in contrast to relationally dissimilar lures (pipe-water). Experiment 2 extended the RLE by showing a continuous effect of relational lure strength on recognition times (RTs), false alarms, and hits. It used a continuous pair recognition task, where each recombined lure or target could be preceded by 0, 1, 2, 3 or 4 different exemplars of the same relation. RTs and false alarms increased linearly with the number of different previously seen relationally similar pairs. Moreover, more typical exemplars of a given relation lead to a stronger RLE. Finally, hits for intact pairs also rose with the number of previously studied different relational instances. These results suggest that semantic relations exist as independent representations in LTM and that during associative recognition these representations can be a spurious source of familiarity. We discuss the implications of the RLE for current models of semantic and episodic memory, unitization in associative recognition, analogical reasoning and retrieval, as well as constructive memory research.

How relatives of patients with head and neck cancer experience pain, disease progression and treatment: a qualitative interview study.

PubMed

Schaller, Anne; Liedberg, Gunilla M; Larsson, Britt

2014-08-01

This study of relatives to patients with head and neck cancer (HNC) treated with radiotherapy describes how the relatives experienced the patient's situation, especially with respect to pain, and how the relatives themselves experienced the situation. Semi-structured interviews of 21 relatives to HNC patients who suffered from pain were conducted, and a qualitative content analysis was performed. The relatives experienced that the patients suffered from physical, psychological, and social pain. A dark picture consisting of lack of participation and knowledge, psychological distress, and lack of support were reported. Thus, a main category: relatives struggle with loved one's pains related to head and neck cancer treatment and with their own demanding situation - was based on the following four categories: inability to relieve and comprehend the physical suffering of the patients; overwhelming emotions were experienced that affect the patients and the relatives themselves; in need of support from the health care service; and altered daily activities and family roles due to illness and treatment. In patients physical, psychological, and social pain were prominent and in relatives psychological distress, lack of knowledge and support were experienced. Thus, to reduce pain and anxiety in patients and relatives, the health care professionals should provide relevant knowledge about pain management. The health care professionals should also provide educational interventions that address the psychological and social factors that impact pain for HNC patients and their relatives. Well-thought supporting care and easily accessible information about practical concerns should be offered to HNC patients and their relatives. Copyright © 2014 Elsevier Ltd. All rights reserved.

Relational Aggression, Victimization and Self-Concept: Testing Pathways from Middle Childhood to Adolescence.

PubMed

Blakely-McClure, Sarah J; Ostrov, Jamie M

2016-02-01

When studying adolescent development, it is important to consider two key areas that are salient for teens, which are self-concept and peer relations. A secondary analysis of the National Institute of Health and Human Development Study of Early Child Care and Youth Development was conducted to examine the prospective bidirectional associations between self-concept and peer relations. To date, how social development broadly and peer relations in particular (e.g., relational aggression and victimization) affect self-concept domains is not fully understood. Using a large sample (N = 1063; 532 girls; M = 11.14 years; SD = .59) with multiple informants, the present study examined whether fifth grade relational aggression and sixth grade relational victimization was associated with adolescent self-concept in three key domains (i.e., academic, sports, physical appearance). A significant direct effect emerged, such that relational aggression in middle childhood was associated with decreases in academic self-concept and increases in sports self-concept in adolescence. Analyses also revealed that having higher levels of domain specific self-concept led to decreases in relational aggression across the transition to adolescence. The findings highlight the importance of examining bidirectional prospective associations between relational aggression, relational victimization, and domain specific self-concept. Implications for future research and clinical intervention are discussed.

Gender relations and health research: a review of current practices

PubMed Central

2011-01-01

Introduction The importance of gender in understanding health practices and illness experiences is increasingly recognized, and key to this work is a better understanding of the application of gender relations. The influence of masculinities and femininities, and the interplay within and between them manifests within relations and interactions among couples, family members and peers to influence health behaviours and outcomes. Methods To explore how conceptualizations of gender relations have been integrated in health research a scoping review of the existing literature was conducted. The key terms gender relations, gender interactions, relations gender, partner communication, femininities and masculinities were used to search online databases. Results Through analysis of this literature we identified two main ways gender relations were integrated in health research: a) as emergent findings; and b) as a basis for research design. In the latter, gender relations are included in conceptual frameworks, guide data collection and are used to direct data analysis. Conclusions Current uses of gender relations are typically positioned within intimate heterosexual couples whereby single narratives (i.e., either men or women) are used to explore the influence and/or impact of intimate partner gender relations on health and illness issues. Recommendations for advancing gender relations and health research are discussed. This research has the potential to reduce gender inequities in health. PMID:22151578

Neurocognitive processes of linguistic cues related to death.

2010-10-01

Consciousness of the finiteness of one's personal existence influences human thoughts and behaviors tremendously. However, the neural substrates underlying the processing of death-related information remain unclear. The current study addressed this issue by scanning 20 female adults, using functional magnetic resonance imaging, in a modified Stroop task that required naming colors of death-related, negative-valence, and neutral-valence words. We found that, while both death-related and negative-valence words increased activity in the precuneus/posterior cingulate and lateral frontal cortex relative to neutral-valence words, the neural correlate of the processing of death-related words was characterized by decreased activity in bilateral insula relative to both negative-valence and neutral-valence words. Moreover, the decreased activity in the left insula correlated with subjective ratings of death relevance of death-related words and the decreased activity in the right insula correlated with subjective ratings of arousal induced by death-related words. Our fMRI findings suggest that, while both death-related and negative-valence words are associated with enhanced arousal and emotion regulation, the processing of linguistic cues related to death is associated with modulations of the activity in the insula that mediates neural representation of the sentient self.

The current study aimed to test a Relational Frame Theory (RFT) model of analogical reasoning based on the relating of derived same and derived difference relations. Experiment 1 recorded reaction time measures of similar–similar (e.g., “apple is to orange as dog is to cat”) versus different–different (e.g., “he is to his brother as chalk is to cheese”) derived relational responding, in both speed-contingent and speed-noncontingent conditions. Experiment 2 examined the event-related potentials (ERPs) associated with these two response patterns. Both experiments showed similar–similar responding to be significantly faster than different–different responding. Experiment 2 revealed significant differences between the waveforms of the two response patterns in the left-hemispheric prefrontal regions; different–different waveforms were significantly more negative than similar–similar waveforms. The behavioral and neurophysiological data support the RFT prediction that, all things being equal, similar–similar responding is relationally “simpler” than, and functionally distinct from, different–different analogical responding. The ERP data were fully consistent with findings in the neurocognitive literature on analogy. These findings strengthen the validity of the RFT model of analogical reasoning and supplement the behavior-analytic approach to analogy based on the relating of derived relations. PMID:16596974

Formation of new stimulus equivalence classes by exclusion.

Plazas, Elberto A; Villamil, Carlos-Wilcen

2018-03-01

This study presents three experiments that aimed to show the formation of stimulus equivalence relations among stimuli that had been previously related only by exclusion. In Experiment 1, participants were trained on baseline conditional discriminations to establish two 3-member equivalence classes. Then, they were exposed to exclusion trials, without feedback, in which undefined stimuli had to be matched by rejecting the defined baseline stimuli. Finally, participants responded to test trials evaluating the emergence of symmetry and transitivity among the undefined stimuli from the exclusion trials. For half of the participants, the stimuli related by exclusion were introduced as S- stimuli in the baseline trials, whereas for the other half they were not. Further, half of the participants were assessed for emergent relations with stimuli from all the classes, whereas the other half was assessed for emergent relations with only the stimuli related by exclusion. In Experiment 2, the S- comparisons in the emergent relations test trials with stimuli only related by exclusion were stimuli from a null class. In Experiment 3, the number of exclusion trials was doubled. Across experiments, most participants showed emergence of equivalence relations among the stimuli related by exclusion. Some conditions of stimulus control associated with exclusion learning and the emergence of equivalence relations are discussed. © 2018 Society for the Experimental Analysis of Behavior.

In the present study, we investigated the relationship among three emotion-motivation systems (adult attachment, romantic love, and sex). We recorded event-related potentials in 37 healthy volunteers who had experienced romantic love while they viewed SEX, LOVE, FRIEND, SPORT, and NEUTRAL images. We also measured adult attachment styles, level of passionate love and sexual attitudes. As expected, results showed that, firstly, response to love-related image-stimuli and sex-related image-stimuli on the electrophysiological data significantly different on N1, N2, and positive slow wave (PSW) components. Secondly, the different adult attachment styles affected individuals’ recognition processing in response to love-related and sex-related images, especially, to sex-related images. Further analysis showed that voltages elicited by fearful attachment style individuals were significantly lower than voltages elicited by secure and dismissing attachment style individuals on sex-related images at frontal sites, on N1 and N2 components. Thirdly, from behavior data, we found that adult attachment styles were not significantly related to any dimension of sexual attitudes but were significantly related to passionate love scale (PLS) total points. Thus, the behavior results were not in line with the electrophysiological results. The present study proved that adult attachment styles might mediate individuals’ lust and attraction systems.

This study examines spatial relationships between alcohol outlet density and the incidence of alcohol-related crashes. The few prior studies conducted in this area used relatively large spatial units; here we use highly resolved units from Melbourne, Australia (Statistical Area level 1 [SA1] units: mean land area=0.5 km(2); SD=2.2 km(2)), in order to assess different micro-scale spatial relationships for on- and off-premise outlets. Bayesian conditional autoregressive Poisson models were used to assess cross-sectional relationships of three-year counts of alcohol-related crashes (2010-2012) attended by Ambulance Victoria paramedics to densities of bars, restaurants, and off-premise outlets controlling for other land use, demographic and roadway characteristics. Alcohol-related crashes were not related to bar density within local SA1 units, but were positively related to bar density in adjacent SA1 units. Alcohol-related crashes were negatively related to off-premise outlet density in local SA1 units. Examined in one metropolitan area using small spatial units, bar density is related to greater crash risk in surrounding areas. Observed negative relationships for off-premise outlets may be because the origins and destinations of alcohol-affected journeys are in distal locations relative to outlets.

2015-01-01

High anxiety sensitivity (AS) has been associated with elevated pain-related anxiety in anxiety and pain samples. The present study investigated (a) the associations among the lower order dimensions of AS and pain-related anxiety, using a robust measure of AS, and (b) the pain-related anxiety outcomes of a telephone-delivered cognitive behavioural treatment (CBT) designed to reduce high AS. Participants were 80 anxiety treatment-seeking participants with high AS (M age = 36 years; 79% women). After providing baseline data on AS and pain-related anxiety, participants were randomly assigned to an eight-week telephone CBT or a waiting list control. At baseline, bivariate correlations showed AS physical and cognitive, but not social, concerns were significantly associated with pain-related fear and arousal but not escape/avoidance behaviours. Multiple regression revealed that after accounting for emotional distress symptoms, AS physical, but not cognitive or social, concerns uniquely predicted pain-related anxiety. Multilevel modelling showed that the AS-targeted CBT reduced pain-related anxiety and treatment-related changes in global AS and AS physical concerns mediated changes in pain-related anxiety. Results suggest that an AS-targeted intervention may have implications for reducing pain-related anxiety. Further research is needed in a chronic pain sample.

Studies on Intervention Process Evaluation are attracting growing attention in the literature on interventions linked to stress and the wellbeing of workers. There is evidence that some elements relating to the process and content of an intervention may have a decisive role in implementing it by facilitating or hindering the effectiveness of the results. This study aimed to provide a process evaluation on interventions to assess and manage risks related to work-related stress using a methodological path offered by INAIL. The final sample is composed of 124 companies participating to an interview on aspects relating to each phase of the INAIL methodological path put in place to implement the intervention. INAIL methodology has been defined as useful in the process of assessing and managing the risks related to work-related stress. Some factors related to the process (e.g., implementation of a preliminary phase, workers' involvement, and use of external consultants) showed a role in significant differences that emerged in the levels of risk, particularly in relation to findings from the preliminary assessment. Main findings provide information on the key aspects of process and content that are useful in implementing an intervention for assessing and managing risks related to work-related stress.

The broad purpose of this research is to identify the key modifiable variables most related to elders' life satisfaction and empowerment in order to improve the efficacy of interventions projects. Our study aims to integrate the theoretical perspectives of personality and community psychology focusing both on dispositional characteristics and relational well-being of elders, investigating triads, composed by an elder, a paid caregiver and the most involved relative. This study explores the impact of (1) some socio-demographic characteristics of elders, (2) some modifiable dispositional variables of elders and (3) elders' relational well-being on elders' empowerment and life satisfaction. The study involved 429 people in 143 triads. Semi-structured interviews with elders, paid caregiver and close relatives were used to construct a new pilot measure of elders' relational well-being. Life Satisfaction, Empowerment, Loneliness, Positivity, Humor and Emotions self-efficacy scales were also administered. Hierarchical multiple regressions were performed. Elders' positivity, relational well-being of elders and living alone were significantly related to empowerment. Elders' relational well-being and positivity significantly contributed to life satisfaction. Interventions to increase empowerment and life satisfaction should focus primarily on augmenting positivity and relational well-being integrating the theoretical premises of both personality and community psychology.

Do You Have Anything to Hide? Infidelity-Related Behaviors on Social Media Sites and Marital Satisfaction.

PubMed

McDaniel, Brandon T; Drouin, Michelle; Cravens, Jaclyn D

2017-01-01

Social media provides one route to behaviors that may be potentially harmful to romantic relationships, such as communicating with alternative partners, which can sometimes create relationship conflict, breakups, or divorce. Limited empirical evidence exists concerning social media infidelity-related behaviors and marital relationships. This study examined whether married/cohabiting individuals are using social media sites to engage in online infidelity-related behaviors and to what extent this related to relationship satisfaction, ambivalence, and relational attachment characteristics as reported by 338 married/cohabiting individuals from 176 families. Only a small percentage of married/cohabiting couples reported engaging in social media infidelity-related behaviors; however, more engagement in infidelity-related behaviors on social media was significantly related to lower relationship satisfaction, higher relationship ambivalence, and greater attachment avoidance and anxiety in both women and men. Additionally, attachment anxiety and gender interacted with relationship satisfaction in predicting online infidelity-related behaviors when controlling for other variables. Implications are discussed.

Emotion-related self-regulation and its relation to children's maladjustment.

PubMed

Eisenberg, Nancy; Spinrad, Tracy L; Eggum, Natalie D

2010-01-01

The development of children's emotion-related self-regulation appears to be related to, and likely involved in, many aspects of children's development. In this review, the distinction between effortful self-regulatory processes and those that are somewhat less voluntary is discussed, and literature on the former capacities is reviewed. Emotion-related self-regulation develops rapidly in the early years of life and improves more slowly into adulthood. Individual differences in children's self-regulation are fairly stable after the first year or two of life. Such individual differences are inversely related to at least some types of externalizing problems. Findings for internalizing problems are less consistent and robust, although emotion-related self-regulation appears to be inversely related to internalizing problems after the early years. Self-regulatory capacities have been related to both genetic and environmental factors and their interaction. Some interventions designed to foster self-regulation and, hence, reduce maladjustment, have proved to be at least partially effective.

Effects of work stress on work-related rumination, restful sleep, and nocturnal heart rate variability experienced on workdays and weekends.

PubMed

Vahle-Hinz, Tim; Bamberg, Eva; Dettmers, Jan; Friedrich, Niklas; Keller, Monika

2014-04-01

The present study reports the lagged effects of work stress on work-related rumination, restful sleep, and nocturnal heart rate variability experienced during both workdays and weekends. Fifty employees participated in a diary study. Multilevel and regression analyses revealed a significant relationship between work stress measured at the end of a workday, work-related rumination measured during the evening, and restful sleep measured the following morning. Work stress, measured as the mean of 2 consecutive workdays, was substantially but not significantly related to restful sleep on weekends. Work stress was unrelated to nocturnal heart rate variability. Work-related rumination was related to restful sleep on weekends but not on workdays. Additionally, work-related rumination on weekends was positively related to nocturnal heart rate variability during the night between Saturday and Sunday. No mediation effects of work stress on restful sleep or nocturnal heart rate variability via work-related rumination were confirmed.

Ayotte, Brian; Mehta, Clare; Alfonso, Jacqueline

2017-09-01

Objective We examined health-related communication between same-sex and other-sex friends and how communication was related to health-related behavior. Participants Data from 243 emerging adults attending college ( Mage = 18.96, SD = 1.43; 55.6% male) were analyzed. Methods Participants completed measures assessing the frequency in which they talked about and made plans to engage in exercise and nutrition-related behaviors with friends, as well as how often they engaged in exercise and nutrition-related behaviors. Results In general, participants reported more health-related communication with same-sex friends. Health-related communication with same-sex friends was positively related to health behaviors for men and women. However, the pattern of results differed for men and women depending on the topic of communication and the behavior being examined. Conclusion Our study extends the literature by examining the role of sex of friends in health communication and planning and how interactions with friends relate to health-promoting behavior.

A Structural Equation Model of HIV-related Symptoms, Depressive Symptoms, and Medication Adherence.

2016-05-01

Adherence to combined antiretroviral therapy (cART) remains critical in management of HIV infection. This study evaluated depression as a potential mechanism by which HIV-related symptoms affect medication adherence and explored if particular clusters of HIV symptoms are susceptible to this mechanism. Baseline data from a multi-visit intervention study were analyzed among 124 persons living with HIV (PLWH). A bifactor model showed two clusters of HIV-related symptom distress: general HIV-related symptoms and gastrointestinal (GI) symptoms. Structural equation modeling showed that both general HIV-related symptoms and GI symptoms were related to higher levels of depressive symptoms, and higher levels of depressive symptoms were related to lower levels of medication adherence. Although general HIV-related symptoms and GI symptoms were not directly related to adherence, they were indirectly associated with adherence via depression. The findings highlight the importance of early recognition and evaluation of symptoms of depression, as well as the underlying physical symptoms that might cause depression, to improve medication adherence.

Subjective relative deprivation is associated with poorer physical and mental health.

PubMed

Mishra, Sandeep; Carleton, R Nicholas

2015-12-01

Substantial epidemiological evidence has shown that income inequality and objective measures of relative deprivation are associated with poorer health outcomes. However, surprisingly little research has examined whether subjective feelings of relative deprivation are similarly linked with poorer health outcomes. The relative deprivation hypothesis suggests that inequality affects health at the individual level through negative consequences of social comparison. We directly examined the relationship between subjective feelings of personal relative deprivation and self-reported physical and mental health in a diverse community sample (n = 328). Results demonstrated that subjective feelings of personal relative deprivation are associated with significantly poorer physical and mental health. These relationships held even when accounting for covariates that have been previously associated with both relative deprivation and health. These results further support the link between relative deprivation and health outcomes and suggest that addressing root causes of relative deprivation may lead to greater individual health.

Media use and ADHD-related behaviors in children and adolescents: A meta-analysis.

PubMed

Nikkelen, Sanne W C; Valkenburg, Patti M; Huizinga, Mariette; Bushman, Brad J

2014-09-01

There are several theoretical reasons to believe that media use might be related to attention-deficit/hyperactivity disorder (ADHD) or ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Although studies into the media-ADHD relationship have accumulated, they have yielded inconsistent results. Therefore, we still do not know whether children's media use and ADHD-related behaviors are related and, if so, under which conditions. To fill this gap in the literature, we first identified 6 different hypotheses that may explain why media use in general and viewing fast-paced or violent media content might be related to 1 or more ADHD-related behaviors. Subsequently, we conducted a meta-analysis of 45 empirical studies investigating the relationship between media use and ADHD-related behaviors in children and adolescents. Our results indicated a small significant relationship between media use and ADHD-related behaviors (r+ = .12). Finally, we identified several specific gaps in the existing literature and presented 5 crucial directions for future research.

Use of indigenous cultural idioms by Chinese immigrant relatives for psychosis: impacts on stigma and psychoeducational approaches.

PubMed

Yang, Lawrence H; Singla, Daisy R

2011-11-01

Indigenous interpretations of mental illness might negatively impact treatment adherence. However, psychiatric "labeling" potentially leads to stigma among Chinese groups, thus encouraging the use of indigenous idioms. We examined how relatives' use of indigenous labeling varied with the consumers' experience of illness and whether indigenous labeling protected relatives from internalized and experienced forms of stigma. Forty-nine relatives of Chinese-immigrant consumers with psychosis were sampled. Although consumers had progressed to the middle stages of psychosis, 39% of relatives used indigenous idioms to label psychosis. Indigenous labeling decreased when illness duration increased and when visual hallucinations were present. Indigenous labeling further predicted lower internalized stigma among relatives. Relatives who used indigenous labeling also reported fewer indirect stigma experiences, although not after controlling for illness severity. The frequency of direct discrimination among relatives did not differ by labeling. These forms of felt stigma might be embedded into relatives' psychoeducation programs to mitigate adverse consequences of psychiatric labeling.

Body-related envy: a social comparison perspective in sport and exercise.

PubMed

Pila, Eva; Stamiris, Angela; Castonguay, Andree; Sabiston, Catherine M

2014-02-01

These three studies sought to better understand experiences of body-related envy and to examine the association with motivation and exercise behavior in young adult males and females. In an interview study, participants (N = 11) discussed body-related envy within a framework of social comparison. In Study 2, a thematic content analysis was conducted on self-reported narratives of body-related envy experiences reported by 288 participants. Themes of body-related envy triggers, cognitions, and cognitive and behavioral outcomes were identified. Findings from Studies 1 and 2 highlighted the possible link between body-related envy and exercise motivation and behavior. Study 3 tested these associations with males and females (N = 595) who completed a self-report questionnaire. In the structural equation model, body-related envy was positively associated with external, introjected, and identified regulations, and identified regulation was positively associated with exercise behavior. Taken together, the importance of body-related envy in the experience of cognitive, affective, and behavioral outcomes related to sport and exercise contexts is highlighted.

The Relation Between Use of Mobile Electronic Devices and Bedtime Resistance, Sleep Duration, and Daytime Sleepiness Among Preschoolers.

PubMed

Nathanson, Amy I; Beyens, Ine

2018-01-01

This study investigated the relation between preschoolers' mobile electronic device (MED) use and sleep disturbances. A national sample of 402 predominantly college-educated and Caucasian mothers of 3-5-year-olds completed a survey assessing their preschoolers' MED use, bedtime resistance, sleep duration, and daytime sleepiness. Heavier evening and daily tablet use (and to some extent, smartphone use) were related to sleep disturbances. Other forms of MED use were not consistently related to sleep disturbances. In addition, playing games on MEDs at bedtime was related to compromised sleep duration, although other forms of MED use at bedtime were not related to sleep outcomes. Although the relations between MED use and sleep disturbances were small in size, they were larger than the relations between sleep and other predictors in the models. Continued work should investigate how MED exposure is related to children's cognitive, psychological, emotional, and physiological development, particularly given the popularity and widespread use of these devices.

A meta-analysis of work-family conflict and various outcomes with a special emphasis on cross-domain versus matching-domain relations.

PubMed

Amstad, Fabienne T; Meier, Laurenz L; Fasel, Ursula; Elfering, Achim; Semmer, Norbert K

2011-04-01

A literature review of studies analyzing work-family conflict and its consequences was conducted, and 427 effect sizes were analyzed meta-analytically. Work-family conflict was analyzed bidirectionally in terms of work interference with family (WIF) and family interference with work (FIW). We assessed 3 categories of potential outcomes: work-related outcomes, family-related outcomes, and domain-unspecific outcomes. Results show that WIF and FIW are consistently related to all 3 types of outcomes. Both types of interrole conflict showed stronger relationships to same-domain outcomes than to cross-domain outcomes. Thus, WIF was more strongly associated with work-related than with family-related outcomes, and FIW was more strongly associated with family-related than with work-related outcomes. In moderator analyses, parenthood could not explain variability in effect sizes. However, time spent at work did moderate the relationships between WIF and family-related outcomes, as well as FIW and domain-unspecific outcomes.

Reciprocal Relations between Work-Related Authenticity and Intrinsic Motivation, Work Ability and Depressivity: A Two-Wave Study.

PubMed

Emmerich, Astrid I; Rigotti, Thomas

2017-01-01

This study investigates the role of context-specific authenticity at work for work-related outcomes (intrinsic motivation, work ability) and depressivity. Furthermore reciprocal relations between work-related authenticity and healthy psychological functioning are investigated. Longitudinal data from 1,243 employees from 63 subsidiaries of a non-profit organization in the social sector were analyzed using multilevel structural equation modeling. Work-related authenticity at T1 predicted work ability and depressivity, but not intrinsic motivation at T2, about 6 months later. Work-related authenticity at T2 was predicted by intrinsic motivation and depressivity, but not by work ability at T1. We conclude that work-related authenticity and healthy psychological functioning are positively reinforcing each other. Thus, enabling employees to be authentic supposedly increases their well-being and is a pivotal opportunity for organizations to foster health and performance-related indicators like work ability and prevent negative health indicators like depressivity. At the same time, authenticity of employees can be fostered through workplace health promotion.

Objectives: To evaluate relatives' attitudes towards informing patients with Alzheimer's disease (AD) about their diagnosis. Setting: A university hospital in Italy. Methods: The closest relatives of each of 71 subjects diagnosed for the first time as having AD were interviewed, using a semistructured questionnaire. Spontaneous requests by relatives not to communicate issues concerning the diagnosis were also recorded. Results: Forty three (60.6%) relatives spontaneously requested that patients not be fully informed. After being interviewed, nobody thought that the patient should be given all the information. Justifications were related to the fear of the onset or worsening of depressive symptoms in the patient. Conclusions: In Italy relatives' opposition to informing AD patients appears to be common. Knowledge of the relatives' attitudes may be useful for clinicians but disclosure of diagnosis should be based on the clinical evaluation of the patient and on a prudent evaluation of the relationship between the patient and her/his relative caregiver.

To quantify the occurrence of deaths directly associated with urban violence among fatal work-related accidents. Verbal autopsies were performed with the relatives and coworkers of residents of Campinas, state of São Paulo, Brazil, who died from external causes in 2015. We have also analyzed police reports and reports of the Legal Medical Institute related to these deaths. We have identified 82 fatal work-related accidents in Campinas in 2015, of which 25 were murders, 35 were traffic accidents not directly related to work activities, and three were suicides at work. The proportional mortality rate for homicides, traffic accidents, and suicides among fatal work-related accidents was estimated at 30.5%, 42.7%, and 3.7%, respectively. Urban violence accounted for three-fourths of the fatal work-related accidents recorded in the period studied.

Background: The well-being of relatives of patients having chronic heart diseases (CHD) has been found to be negatively affected by the patient’s condition. Studies examining relatives of patients with atrial fibrillation (AF) indicate that their well-being may be affected in a similar manner, but further research is needed. Aim: To explore and describe critical incidents in which relatives of patients experience how AF affects their well-being and what actions they take to handle these situations. Design and method: An explorative, descriptive design based on the critical incident technique (CIT) was used. Interviews were conducted with 19 relatives (14 women and five men) of patients hospitalised in southern Sweden due to acute symptoms of the AF. Results: The well-being of relatives was found to be affected by their worries (patient-related health), as well as the sacri-ficing of their own needs (self-related health). In handling their own well-being, these relatives adjusted to and supported the patient (practical involvement), along with adjusting their own feelings and responding to the mood of the patients (emotional involvement). Conclusion: The well-being of relatives of patients with AF was affected depending on the patients’ well-being. In their attempt to handle their own well-being, the relatives adjusted to and supported the patients. Further research is needed in order to evaluate the effects of support to relatives and patients respectively and together. PMID:25419253

Models as Relational Categories

Kokkonen, Tommi

2017-11-01

Model-based learning (MBL) has an established position within science education. It has been found to enhance conceptual understanding and provide a way for engaging students in authentic scientific activity. Despite ample research, few studies have examined the cognitive processes regarding learning scientific concepts within MBL. On the other hand, recent research within cognitive science has examined the learning of so-called relational categories. Relational categories are categories whose membership is determined on the basis of the common relational structure. In this theoretical paper, I argue that viewing models as relational categories provides a well-motivated cognitive basis for MBL. I discuss the different roles of models and modeling within MBL (using ready-made models, constructive modeling, and generative modeling) and discern the related cognitive aspects brought forward by the reinterpretation of models as relational categories. I will argue that relational knowledge is vital in learning novel models and in the transfer of learning. Moreover, relational knowledge underlies the coherent, hierarchical knowledge of experts. Lastly, I will examine how the format of external representations may affect the learning of models and the relevant relations. The nature of the learning mechanisms underlying students' mental representations of models is an interesting open question to be examined. Furthermore, the ways in which the expert-like knowledge develops and how to best support it is in need of more research. The discussion and conceptualization of models as relational categories allows discerning students' mental representations of models in terms of evolving relational structures in greater detail than previously done.

Organization, relational justice and absenteeism.

There is a need for more knowledge on how to manage companies towards healthier and more prosperous organizations with low levels of absenteeism. Relational Justice can be a useful concept when managing such organizations. Organizational factors can help to explain why some companies have relatively low absenteeism rates, even though they are equal to other companies in many other aspects. Previous studies suggest that management may be one important factor. Efficient management may depend on good relations between the leaders and the employees. The concept of Relational Justice is designed to capture these relations. Consequently, a Relational Justice framework may be used to understand why some companies have a low incidence of absenteeism. Managers from a representative body of Swedish companies. Interviews were analyzed to explore whether the items representing the concept of Relational Justice can be used to further understand the strategies, procedures and structures that characterize organizations and management in companies with a low incidence of absenteeism. Strategies, procedures or principles related to Relational Justice were common and highlighted in companies with an incidence of absenteeism. The most frequently occurring factors were; to be treated with kindness and consideration, personal viewpoint considered and to be treated impartially. The results suggested that a Relational Justice framework could be used to increase understanding of the organizational and managerial factors typical for companies with a low incidence of absenteeism. A Relational Justice approach to organizational management may be used to successfully lower absenteeism, change organizations and promote healthy and prosperous companies.

Influence of affective significance on different levels of processing using pupil dilation in an analogical reasoning task.

2011-02-01

The present study investigates the interaction of cognition and emotion in decision making, using an analogical reasoning task. In this task, two word pairs were presented simultaneously. Each word pair could be characterized by an associative conceptual relation (object, actor, or location relation) as well as an emotional relation (negative, neutral, or positive valence). Both types of relations were equally task-relevant: Participants had to identify both types of relations, to compare them, and to decide whether or not the word pairs were analogous, i.e., corresponding in both conceptual and emotional relations. Behavioral data showed that emotional relations were identified preferentially and faster than conceptual relations. Pupil dilations reflected the descending difficulty of the conditions and were greatest in amplitude when both conceptual and emotional correspondence was shown, intermediate when only one type of relation (either the emotional or the conceptual) corresponded, and least when neither correspondence existed. Additionally, a negative valence of the word material slowed down response times and increased pupil dilation relative to positive and neutral items. In summary, pupil and response time data together support recent (neurobiological) models concerning the interaction of emotion and cognition by showing that affective significance leads to a processing advantage at a cognitively lower level of information processing (here, identification or retrieval of relations from long-term memory) but can also distract people from higher level cognitive processes (here, from the controlled comparison of retrieved relations).

Simons, Laura E; Kaczynski, Karen J; Conroy, Caitlin; Logan, Deirdre E

2012-12-01

Recent research has implicated pain-related fear in relation to functional outcomes in children with chronic pain. The current study examined fear of pain, disability, and depression within the context of an intensive pain rehabilitation program. One hundred forty-five children and adolescents who participated in an intensive interdisciplinary pediatric pain rehabilitation day program were assessed in this study. Patients completed measures of pain intensity, pain-related fears, functional disability, and depressive symptoms at admission, discharge, and on average, 2 months postdischarge. After controlling for pain intensity, pain-related fear was significantly related to disability and depressive symptoms at all time points. As predicted, a decline in pain-related fear was significantly associated with a decrease in disability and depressive symptoms. Interestingly, high levels of pain-related fears at admission predicted less reduction in functional disability and depression at discharge, suggesting that high levels of pain-related fear may be a risk factor in relation to treatment outcomes. Overall, results indicate that the relationship between fear of pain and changes in disability and depressive symptoms are closely linked, with fear of pain playing an important role in treatment. This paper presents results underscoring the importance of pain-related fear in relation to treatment response for children and adolescents with chronic pain. These findings support the need to develop and implement interventions that target reductions in pain-related fear. Copyright © 2012 American Pain Society. Published by Elsevier Inc.

2014-09-01

Teachers' content-related knowledge is a key factor influencing the learning progress of students. Different models of content-related knowledge have been proposed by educational researchers; most of them take into account three categories: content knowledge, pedagogical content knowledge, and curricular knowledge. As there is no consensus about the empirical separability (i.e. empirical structure) of content-related knowledge yet, a total of 134 biology teachers from secondary schools completed three tests which were to capture each of the three categories of content-related knowledge. The empirical structure of content-related knowledge was analyzed by Rasch analysis, which suggests content-related knowledge to be composed of (1) content knowledge, (2) pedagogical content knowledge, and (3) curricular knowledge. Pedagogical content knowledge and curricular knowledge are highly related (rlatent = .70). The latent correlations between content knowledge and pedagogical content knowledge (rlatent = .48)-and curricular knowledge, respectively (rlatent = .35)-are moderate to low (all ps < .001). Beyond the empirical structure of content-related knowledge, different learning opportunities for teachers were investigated with regard to their relationship to content knowledge, pedagogical content knowledge, and curricular knowledge acquisition. Our results show that an in-depth training in teacher education, professional development, and teacher self-study are positively related to particular categories of content-related knowledge. Furthermore, our results indicate that teaching experience is negatively related to curricular knowledge, compared to no significant relationship with content knowledge and pedagogical content knowledge.

Assess the association between patient education (i.e. empowering knowledge) and preoperative health-related quality of life, 6 months postoperative health-related quality of life, and the increase in health-related quality of life in osteoarthritis patients who underwent total hip or total knee arthroplasty. This is a cross-cultural comparative follow-up study using structured instruments to measure the difference between expected and received patient education and self-reported health-related quality of life (EQ-5D) in Finland, Greece, Iceland, Spain and Sweden. The health-related quality of life was significantly increased 6 months postoperatively in all countries due to the arthroplasties. In the total sample, higher levels of empowering knowledge were associated with a higher health-related quality of life, both pre- and postoperatively, but not with a higher increase in health-related quality of life. On the national level, postoperative health-related quality of life was associated with higher levels of empowering knowledge in Finland, Iceland and Sweden. The increase in health-related quality of life was associated with levels of empowering knowledge for Greece. Overall, it can be concluded that the level of empowering knowledge was associated with high postoperative health-related quality of life in the total sample, even though there is some variation in the results per country.

To assess the strengths and limitations of different methods for detecting alcohol-related emergency department (ED) presentations and to compare the characteristics of patients who present to the ED with an alcohol-related presentation with ED patients who are found to be risky drinkers by a questionnaire. Survey at two Sydney Australia ED over four weekends of 389 patients. Alcohol-related presentations were identified using a range of methods and were compared with presentations in ED patients who reported risky drinking using the alcohol use disorders identification test (AUDIT). Overall, 20% of ED patients had alcohol-related presentations and 28% were identified as risky drinkers by AUDIT. Diagnostic codes detected only 7% of all alcohol-related ED presentations, compared with 34% detected by nursing triage text, 60% by medical record audits and 69% by self-report. Among risky drinkers, just over half (51%) were not attending for an alcohol-related reason, whereas among alcohol-related ED presentations, nearly a third (31%) were not identified as risky drinkers by AUDIT. Not all patients with an alcohol-related ED presentation usually drink at risky levels, nor do all risky drinkers present to the ED for an alcohol-related reason. The use of routinely recorded nursing triage text detects over a third of alcohol-related ED presentations with no additional burden on busy clinicians. As these data are potentially readily accessible, further research is needed to evaluate their validity for the detection of alcohol-related ED presentations.

Biomedical relation extraction can automatically extract high-quality biomedical relations from biomedical texts, which is a vital step for the mining of biomedical knowledge hidden in the literature. Recurrent neural networks (RNNs) and convolutional neural networks (CNNs) are two major neural network models for biomedical relation extraction. Neural network-based methods for biomedical relation extraction typically focus on the sentence sequence and employ RNNs or CNNs to learn the latent features from sentence sequences separately. However, RNNs and CNNs have their own advantages for biomedical relation extraction. Combining RNNs and CNNs may improve biomedical relation extraction. In this paper, we present a hybrid model for the extraction of biomedical relations that combines RNNs and CNNs. First, the shortest dependency path (SDP) is generated based on the dependency graph of the candidate sentence. To make full use of the SDP, we divide the SDP into a dependency word sequence and a relation sequence. Then, RNNs and CNNs are employed to automatically learn the features from the sentence sequence and the dependency sequences, respectively. Finally, the output features of the RNNs and CNNs are combined to detect and extract biomedical relations. We evaluate our hybrid model using five public (protein-protein interaction) PPI corpora and a (drug-drug interaction) DDI corpus. The experimental results suggest that the advantages of RNNs and CNNs in biomedical relation extraction are complementary. Combining RNNs and CNNs can effectively boost biomedical relation extraction performance. Copyright © 2018 Elsevier Inc. All rights reserved.

No dramatic age-related loss of hair cells and spiral ganglion neurons in Bcl-2 over-expression mice or Bax null mice

PubMed Central

2010-01-01

Age-related decline of neuronal function is associated with age-related structural changes. In the central nervous system, age-related decline of cognitive performance is thought to be caused by synaptic loss instead of neuronal loss. However, in the cochlea, age-related loss of hair cells and spiral ganglion neurons (SGNs) is consistently observed in a variety of species, including humans. Since age-related loss of these cells is a major contributing factor to presbycusis, it is important to study possible molecular mechanisms underlying this age-related cell death. Previous studies suggested that apoptotic pathways were involved in age-related loss of hair cells and SGNs. In the present study, we examined the role of Bcl-2 gene in age-related hearing loss. In one transgenic mouse line over-expressing human Bcl-2, there were no significant differences between transgenic mice and wild type littermate controls in their hearing thresholds during aging. Histological analysis of the hair cells and SGNs showed no significant conservation of these cells in transgenic animals compared to the wild type controls during aging. These data suggest that Bcl-2 overexpression has no significant effect on age-related loss of hair cells and SGNs. We also found no delay of age-related hearing loss in mice lacking Bax gene. These findings suggest that age-related hearing loss is not through an apoptotic pathway involving key members of Bcl-2 family. PMID:20637089

A service relation model for web-based land cover change detection

Change detection with remotely sensed imagery is a critical step in land cover monitoring and updating. Although a variety of algorithms or models have been developed, none of them can be universal for all cases. The selection of appropriate algorithms and construction of processing workflows depend largely on the expertise of experts about the "algorithm-data" relations among change detection algorithms and the imagery data used. This paper presents a service relation model for land cover change detection by integrating the experts' knowledge about the "algorithm-data" relations into the web-based geo-processing. The "algorithm-data" relations are mapped into a set of web service relations with the analysis of functional and non-functional service semantics. These service relations are further classified into three different levels, i.e., interface, behavior and execution levels. A service relation model is then established using the Object and Relation Diagram (ORD) approach to represent the multi-granularity services and their relations for change detection. A set of semantic matching rules are built and used for deriving on-demand change detection service chains from the service relation model. A web-based prototype system is developed in .NET development environment, which encapsulates nine change detection and pre-processing algorithms and represents their service relations as an ORD. Three test areas from Shandong and Hebei provinces, China with different imagery conditions are selected for online change detection experiments, and the results indicate that on-demand service chains can be generated according to different users' demands.

To use the relation between cigarette consumption and cardiovascular disease to quantify the risk of coronary heart disease and stroke for light smoking (one to five cigarettes/day). Systematic review and meta-analysis. Medline 1946 to May 2015, with manual searches of references. Prospective cohort studies with at least 50 events, reporting hazard ratios or relative risks (both hereafter referred to as relative risk) compared with never smokers or age specific incidence in relation to risk of coronary heart disease or stroke. MOOSE guidelines were followed. For each study, the relative risk was estimated for smoking one, five, or 20 cigarettes per day by using regression modelling between risk and cigarette consumption. Relative risks were adjusted for at least age and often additional confounders. The main measure was the excess relative risk for smoking one cigarette per day (RR 1_per_day -1) expressed as a proportion of that for smoking 20 cigarettes per day (RR 20_per_day -1), expected to be about 5% assuming a linear relation between risk and consumption (as seen with lung cancer). The relative risks for one, five, and 20 cigarettes per day were also pooled across all studies in a random effects meta-analysis. Separate analyses were done for each combination of sex and disorder. The meta-analysis included 55 publications containing 141 cohort studies. Among men, the pooled relative risk for coronary heart disease was 1.48 for smoking one cigarette per day and 2.04 for 20 cigarettes per day, using all studies, but 1.74 and 2.27 among studies in which the relative risk had been adjusted for multiple confounders. Among women, the pooled relative risks were 1.57 and 2.84 for one and 20 cigarettes per day (or 2.19 and 3.95 using relative risks adjusted for multiple factors). Men who smoked one cigarette per day had 46% of the excess relative risk for smoking 20 cigarettes per day (53% using relative risks adjusted for multiple factors), and women had 31% of the excess risk (38% using relative risks adjusted for multiple factors). For stroke, the pooled relative risks for men were 1.25 and 1.64 for smoking one or 20 cigarettes per day (1.30 and 1.56 using relative risks adjusted for multiple factors). In women, the pooled relative risks were 1.31 and 2.16 for smoking one or 20 cigarettes per day (1.46 and 2.42 using relative risks adjusted for multiple factors). The excess risk for stroke associated with one cigarette per day (in relation to 20 cigarettes per day) was 41% for men and 34% for women (or 64% and 36% using relative risks adjusted for multiple factors). Relative risks were generally higher among women than men. Smoking only about one cigarette per day carries a risk of developing coronary heart disease and stroke much greater than expected: around half that for people who smoke 20 per day. No safe level of smoking exists for cardiovascular disease. Smokers should aim to quit instead of cutting down to significantly reduce their risk of these two common major disorders.

Prostate cancer (PC) relative risks (RRs) are typically estimated based on status of close relatives or presence of any affected relatives. This study provides RR estimates using extensive and specific PC family history. A retrospective population-based study was undertaken to estimate RRs for PC based on complete family history of PC. A total of 635,443 males, all with ancestral genealogy data, were analyzed. RRs for PC were determined based upon PC rates estimated from males with no PC family history (without PC in first, second, or third degree relatives). RRs were determined for a variety of constellations, for example, number of first through third degree relatives; named (grandfather, father, uncle, cousins, brothers); maternal, paternal relationships, and age of onset. In the 635,443 males analyzed, 18,105 had PC. First-degree RRs ranged from 2.46 (=1 first-degree relative affected, CI = 2.39-2.53) to 7.65 (=4 first-degree relatives affected, CI = 6.28-9.23). Second-degree RRs for probands with 0 affected first-degree relatives ranged from 1.51 (≥1 second-degree relative affected, CI = 1.47-1.56) to 3.09 (≥5 second-degree relatives affected, CI = 2.32-4.03). Third-degree RRs with 0 affected first- and 0 affected second-degree relatives ranged from 1.15 (≥1 affected third-degree relative, CI = 1.12-1.19) to 1.50 (≥5 affected third-degree relatives, CI = 1.35-1.66). RRs based on age at diagnosis were higher for earlier age at diagnoses; for example, RR = 5.54 for ≥1 first-degree relative diagnosed before age 50 years (CI = 1.12-1.19) and RR = 1.78 for >1 second-degree relative diagnosed before age 50 years, CI = 1.33, 2.33. RRs for equivalent maternal versus paternal family history were not significantly different. A more complete PC family history using close and distant relatives and age at diagnosis results in a wider range of estimates of individual RR that are potentially more accurate than RRs estimated from summary family history. The presence of PC in second- and even third-degree relatives contributes significantly to risk. Maternal family history is just as significant as paternal family history. PC RRs based on a proband's complete constellation of affected relatives will allow patients and care providers to make more informed screening, monitoring, and treatment decisions. © 2014 The Authors.

PubMed related article links identify closely related articles and enhance our ability to navigate the biomedical literature. They are derived by calculating the word similarity between two articles, relating articles with overlapping word content. In this paper, we propose to enrich PubMed with a new type of related article link based on citations within a single sentence (i.e. sentence level co-citations or SLCs). Using different similarity metrics, we demonstrated that articles linked by SLCs are highly related. We also showed that only half of SLCs are found among PubMed related article links. Additionally, we discuss how the citing sentence of an SLC explains the connection between two articles. PMID:20351935

This study validates the Portuguese version of the psychological effects of the relational job characteristics scale among hospital nurses in Portugal and Brazil. Increasing attention has been given to the social dimension of work, following the transition to a service economy. Nevertheless, and despite the unquestionable relational characteristics of nursing work, scarce research has been developed among nurses under a relational job design framework. Moreover, it is important to develop instruments that study the effects of relational job characteristics among nurses. We followed Messick's framework for scale validation, comprising the steps regarding the response process and internal structure, as well as relationships with other variables (work engagement and burnout). Statistical analysis included exploratory factor analysis and confirmatory factor analysis. The psychological effects of the relational job characteristics scale provided evidence of good psychometric properties with Portuguese and Brazilian hospital nurses. Also, the psychological effects of the relational job characteristics are associated with nurses' work-related well-being: positively with work engagement and negatively concerning burnout. Hospitals that foster the relational characteristics of nursing work are contributing to their nurses' work-related well-being, which may be reflected in the quality of care and patient safety. © 2017 John Wiley & Sons Ltd.

Work-related stress management by Finnish enterprises.

Work-related stress has become one of the major problems in working societies and it increases employees' risk of disease. Its importance has been emphasized also due to its' great socio-economic consequences. Different stress management and worksite interventions have been implemented, however, the actual practices in companies have been assessed little. The purpose of this study was to examine how enterprises in Finland manage work-related stress. An assessment of work-related stress methods was conducted in 40 enterprises acting in the metropolitan area of Finland in May 2010 by a questionnaire. The concept of work-related stress was well known by participants. Enterprises rarely had their own work-related stress management protocol even though all of the workplaces had experienced work-related stress at some point. The collaboration between the workplace and occupational health services varied. Companies easily placed the responsibility for work-related stress assessment and handling on occupational health services. Workplaces have to pay more attention to work-related stress and related issues. The easiest way to do this is to collaborate with occupational health services. Protocols for collaboration should be developed jointly using the available models which have been established as cost-effective.

Statistics indicate a high risk of developing work-related musculoskeletal disorders among hospital nurses. The challenge is to understand the associations between musculoskeletal symptoms and various individual and occupational risk factors. This study examined the direct and indirect interactions of various risk factors with musculoskeletal complaints in hospital nurses. In a cross-sectional design, Iranian hospital nurses from Semnan University of Medical Sciences participated in a questionnaire survey reporting their perceived perceptions of various work-related risk factors and musculoskeletal symptoms. We tested our proposed structural equation model to evaluate the relations between latent and observed concepts and the relative importance and strength of exogenous variables in explaining endogenous musculoskeletal complaints. Measurement model fits the data relatively acceptable. Our findings showed direct effects of psychological, role-related and work posture stressors on musculoskeletal complaints. Fatigue mediated the adverse indirect relations of psychological, role-related, work posture and individual factors with musculoskeletal complaints. Structural equation modeling may provide methodological opportunities in occupational health research with a potential to explain the complexity of interactions among risk factors. Prevention of work-related musculoskeletal disorders among nurses must account for physical and psychosocial conditions.

This longitudinal study of 1,447 first-time college students tested separate time-varying covariate models of the relations between academic and social motives/behaviors and alcohol use and related problems from senior year of high school through the end of the second year in college. Structural equation models identified small but significant inverse relations between academic motives/behaviors and alcohol use across all time points, with relations of somewhat larger magnitude between academic motives/behaviors and alcohol-related problems across all semesters other than senior year in high school. At all time points, there were much larger positive relations between social motives/behaviors and alcohol use across all semesters, with smaller but significant relations between social motives/behaviors and alcohol-related problems. Multi-group models found considerable consistency in the relations between motives/behaviors and alcohol-related outcomes across gender, race/ethnicity, and family history of alcohol problems, although academic motives/behaviors played a stronger protective role for women, and social motives were a more robust risk factor for Caucasian and Latino students and individuals with a positive family history of alcohol problems. Implications for alcohol prevention efforts among college students are discussed. Copyright 2009 APA

Consumer-led health-related online sources and their impact on consumers: An integrative review of the literature.

The aim of the review was to describe consumer-led health-related online sources and their impact on consumers. The review was carried out as an integrative literature review. Quantisation and qualitative content analysis were used as the analysis method. The most common method used by the included studies was qualitative content analysis. This review identified the consumer-led health-related online sources used between 2009 and 2016 as health-related online communities, health-related social networking sites and health-related rating websites. These sources had an impact on peer support; empowerment; health literacy; physical, mental and emotional wellbeing; illness management; and relationships between healthcare organisations and consumers. The knowledge of the existence of the health-related online sources provides healthcare organisations with an opportunity to listen to their consumers' 'voice'. The sources make healthcare consumers more competent actors in relation to healthcare, and the knowledge of them is a valuable resource for healthcare organisations. Additionally, these health-related online sources might create an opportunity to reduce the need for drifting among the healthcare services. Healthcare policymakers and organisations could benefit from having a strategy of increasing their health-related online sources.

To investigate behavior-outcome expectancies relating to thinness, dietary restriction, eating, and alcohol consumption in women with bulimia nervosa (BN). Women with BN (N = 29), women with BN and a co-morbid lifetime alcohol use disorder (AUD; N = 18), and control women (N = 24), completed interviews and questionnaires assessing eating- and alcohol-related symptoms, as well as questionnaires measuring expectancies relating to thinness, dietary restriction, eating, and alcohol consumption. Compared with the control group, both bulimic groups reported greater positive expectancies relating to thinness, dietary restriction and eating; expectancy endorsements were also predictive of the severity of eating-related symptoms. Compared with the other groups, the bulimic group with comorbid lifetime AUD had elevated positive alcohol-related expectancies, and alcohol expectancy endorsements predicted severity of alcohol-related symptoms. Women with BN endorsed more positive expectancies relating to thinness, dietary restriction, and eating, whereas women with BN and a lifetime comorbid AUD endorsed more positive alcohol expectancies. The results are consistent with expectancy theory in that positive expectancy endorsements were associated with symptom severity in a syndrome-specific manner. Expectancies related to thinness, dietary restriction, eating, and alcohol consumption in women with BN. (c) 2008 by Wiley Periodicals, Inc.

Associations among visual acuity and vision- and health-related quality of life among patients in the multicenter uveitis steroid treatment trial.

To evaluate the associations between visual acuity and self-reported visual function; visual acuity and health-related quality of life (QoL) metrics; a summary measure of self-reported visual function and health-related QoL; and individual domains of self-reported visual function and health-related QoL in patients with uveitis. Best-corrected visual acuity, vision-related functioning as assessed by the NEI VFQ-25, and health-related QoL as assessed by the SF-36 and EuroQoL EQ-5D questionnaires were obtained at enrollment in a clinical trial of uveitis treatments. Multivariate regression and Spearman correlations were used to evaluate associations between visual acuity, vision-related function, and health-related QoL. Among the 255 patients, median visual acuity in the better-seeing eyes was 20/25, the vision-related function score indicated impairment (median, 60), and health-related QoL scores were within the normal population range. Better visual acuity was predictive of higher visual function scores (P ≤ 0.001), a higher SF-36 physical component score, and a higher EQ-5D health utility score (P < 0.001). The vision-specific function score was predictive of all general health-related QoL (P < 0.001). The correlations between visual function score and general quality of life measures were moderate (ρ = 0.29-0.52). The vision-related function score correlated positively with visual acuity and moderately positively with general QoL measures. Cost-utility analyses relying on changes in generic healthy utility measures will be more likely to detect changes when there are clinically meaningful changes in vision-related function, rather than when there are only changes in visual acuity.

Background Chronic inflammation has been linked to cancers, and use of non-steroidal anti-inflammatory drugs (NSAIDs) has been associated with reduced risk of several cancers. To further refine the magnitude of NSAID-related associations, in particular for cancers related to inflammation, such as alcohol-, infection-, obesity-, and smoking-related cancers, as well as for less common cancers, we evaluated the use of NSAIDs and cancer risk in a very large cohort. We used propensity scores to account for potential selection bias and hypothesized that NSAID use is associated with decreased cancer incidence. Methods We conducted a prospective study among 314,522 participants in the NIH-AARP Diet and Health Study. Individuals who completed the lifestyle questionnaire, which included NSAID use, in 1996–1997 were followed through 2006. Information on cancer incidence was ascertained by linking to cancer registries and vital status databases. Findings During 2,715,994 person-years of follow-up (median 10.1 person-years), there were 51,894 incident cancers. Compared with non-users of NSAIDs, individuals who reported use in the 12 months prior to interview had a significantly lower risk of all inflammation-related cancer, alcohol-related, infection-related, obesity-related, and smoking-related cancers [hazard ratio (HR) (95% CI)) 0.90 (0.87–0.93), 0.80 (0.74–0.85), 0.82 (0.78–0.87), 0.88 (0.84–0.92), and 0.88 (0.85–0.92) respectively)]. Conclusions After accounting for potential selection bias, our data showed an inverse association between NSAID use and alcohol-related, infection-related, obesity-related, and smoking-related cancers and support the hypothesis that inflammation is related to an increased risk of certain cancers.

Fall-related injuries, hospitalizations, and mortality among older persons represent a major public health problem. Owing to aging societies worldwide, a major impact on fall-related health care demand can be expected. We determined time trends in numbers and incidence of fall-related hospital admissions and in admission duration in older adults. Secular trend analysis of fall-related hospital admissions in the older Dutch population from 1981 through 2008, using the National Hospital Discharge Registry. All fall-related hospital admissions in persons 65 years or older were extracted from this database. Outcome measures were the numbers, and the age-specific and age-adjusted incidence rates (per 10,000 persons) of fall-related hospital admissions in each year of the study. From 1981 through 2008, fall-related hospital admissions increased by 137%. The annual age-adjusted incidence growth was 1.3% for men vs 0.7% for women (P < .001). The overall incidence rate increased from 87.7 to 141.2 per 10,000 persons (an increase of 61%). Age-specific incidence increased in all age groups, in both men and women, especially in the oldest old (>75 years). Although the incidence of fall-related hospital admissions increased, the total number of fall-related hospital days was reduced by 20% owing to a reduction in admission duration. In the Netherlands, numbers of fall-related hospital admissions among older persons increased drastically from 1981 through 2008. The increasing fall-related health care demand has been compensated for by a reduced admission duration. These figures demonstrate the need for implementation of falls prevention programs to control for increases of fall-related health care consumption.

We sought to estimate the prevalence of rape-related pregnancy as an indication for abortion at two public Chicago facilities and to describe demographic and clinical correlates of women who terminated rape-related pregnancies. We performed a cross-sectional study of women obtaining abortion at the Center for Reproductive Health (CRH) at University of Illinois Health Sciences Center and Reproductive Health Services (RHS) at John H. Stroger, Jr. Hospital between August 2009 and August 2013. Gestational age limits at CRH and RHS were 23+6 and 13+6weeks, respectively. We estimated the prevalence of rape-related pregnancy based on billing code (CRH) or data from an administrative database (RHS), and examined relationships between rape-related pregnancy and demographic and clinical variables. Included were 19,465 visits for abortion. The majority of patients were Black (85.6%). Prevalence of abortion for rape-related pregnancy was 1.9%, and was higher at CRH (6.9%) than RHS (1.5%). Later gestational age was associated with abortion for rape-related pregnancy (median 12days, p<.001). Younger age and Black race were associated with abortion for rape-related pregnancy at CRH only (p<.001 for both). Chlamydia and gonorrhea infection were no more prevalent among women terminating rape-related pregnancy than among those terminating for other indications. Rape-related pregnancy as an indication for abortion had a low, but clinically significant prevalence at two urban Chicago family planning centers. Later gestational age was associated with abortion for rape-related pregnancy. Rape-related pregnancy may occur with higher prevalence among some subgroups of women seeking abortion than others. Efforts to address rape-related pregnancy in the abortion care setting are needed. Copyright © 2015 Elsevier Inc. All rights reserved.

In order to improve advanced cancer care, evaluations are necessary. An important element of such evaluations is the perspective of the patient's relatives who have the role of being caregivers as well as co-users of the health care system. The aims were to investigate the scale structure of the FAMCARE scale, to investigate satisfaction with advanced cancer care from the perspective of the relatives of a representative sample of advanced cancer patients, and to investigate whether some sub-groups of relatives were more dissatisfied than others. From 977 patients treated at 54 different Danish hospital departments, 569 patients provided us with the name and address of their relative. Of these, 544 received the FAMCARE scale that measures the families' satisfaction with advanced cancer care. For the four FAMCARE sub-scales, internal consistency was analyzed using Cronbach's alpha; convergent and discriminant validity was analyzed using multitrait-scaling analysis. Associations between the relatives' dissatisfaction and clinical and sociodemographic variables were investigated in explorative analyses using multiple logistic regressions. Of the relatives receiving the questionnaire, 467 (86%) responded. The original scale structure of FAMCARE could not be supported in the present sample, and therefore, results are reported at singe-item level. The proportion of dissatisfied relatives ranged from 5% to 28% (median 13%). Highest levels of dissatisfaction were found for time taken to make a diagnosis (28%) and the speed with which symptoms were treated (25%). Younger relatives were more dissatisfied than older relatives. Other sociodemographic and clinical variables had little impact on the relatives' levels of satisfaction. The relatives' level of dissatisfaction with some of the areas included in this survey needs to be taken seriously. Younger relatives were most dissatisfied.

YouTube is now the second most visited site on the internet. The authors aimed to compare characteristics of and messages conveyed by cigarette- and hookah-related videos on YouTube. Systematic search procedures yielded 66 cigarette-related and 61 hookah-related videos. After three trained qualitative researchers used an iterative approach to develop and refine definitions for the coding of variables, two of them independently coded each video for content including positive and negative associations with smoking and major content type. Median view counts were 606,884 for cigarettes-related videos and 102,307 for hookah-related videos (p<0.001). However, the number of comments per 1000 views was significantly lower for cigarette-related videos than for hookah-related videos (1.6 vs 2.5, p=0.003). There was no significant difference in the number of 'like' designations per 100 reactions (91 vs 87, p=0.39). Cigarette-related videos were less likely than hookah-related videos to portray tobacco use in a positive light (24% vs 92%, p<0.001). In addition, cigarette-related videos were more likely to be of high production quality (42% vs 5%, p<0.001), to mention short-term consequences (50% vs 18%, p<0.001) and long-term consequences (44% vs 2%, p<0.001) of tobacco use, to contain explicit antismoking messages (39% vs 0%, p<0.001) and to provide specific information on how to quit tobacco use (21% vs 0%, p<0.001). Although internet user-generated videos related to cigarette smoking often acknowledge harmful consequences and provide explicit antismoking messages, hookah-related videos do not. It may be valuable for public health programmes to correct common misconceptions regarding hookah use.

A Combination of Thematic and Similarity-Based Semantic Processes Confers Resistance to Deficit Following Left Hemisphere Stroke

PubMed Central

Kalénine, Solène; Mirman, Daniel; Buxbaum, Laurel J.

2012-01-01

Semantic knowledge may be organized in terms of similarity relations based on shared features and/or complementary relations based on co-occurrence in events. Thus, relationships between manipulable objects such as tools may be defined by their functional properties (what the objects are used for) or thematic properties (e.g., what the objects are used with or on). A recent study from our laboratory used eye-tracking to examine incidental activation of semantic relations in a word–picture matching task and found relatively early activation of thematic relations (e.g., broom–dustpan), later activation of general functional relations (e.g., broom–sponge), and an intermediate pattern for specific functional relations (e.g., broom–vacuum cleaner). Combined with other recent studies, these results suggest that there are distinct semantic systems for thematic and similarity-based knowledge and that the “specific function” condition drew on both systems. This predicts that left hemisphere stroke that damages either system (but not both) may spare specific function processing. The present experiment tested these hypotheses using the same experimental paradigm with participants with left hemisphere lesions (N = 17). The results revealed that, compared to neurologically intact controls (N = 12), stroke participants showed later activation of thematic and general function relations, but activation of specific function relations was spared and was significantly earlier for stroke participants than controls. Across the stroke participants, activation of thematic and general function relations was negatively correlated, further suggesting that damage tended to affect either one semantic system or the other. These results support the distinction between similarity-based and complementarity-based semantic relations and suggest that relations that draw on both systems are relatively more robust to damage.

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

To understand whether patient-reported experiences with lung cancer may create teachable moments (TM) for their relatives as evidenced by shifts in their risk perceptions, affective response, and self-image and in turn, motivation to quit smoking. Patients at a comprehensive cancer center (n = 152) completed a survey within 6 months of lung cancer diagnosis to assess their cancer-related symptoms and openness and enumerated relatives who were smokers. Relative smokers (n = 218) then completed a survey assessing their risk perceptions, affective response, and self-image as a smoker related to the patient's diagnosis (TM mechanisms), and their motivation to quit smoking. Cross-sectional mediation and moderation analyses were conducted to explore the links between patient-reported experiences, and relatives' TM mechanisms, and motivation to quit smoking. Relative-reported affect was a significant mediator of the association between patient-reported symptoms and relative smoker's desire to quit. Relatives' self-image was a significant moderator of the association between patient-reported symptoms and relative smoker's desire to quit, such that patients' reported symptoms were associated with relatives' desire to quit only when the relative smoker reported a generally positive self-image as a smoker. No evidence was found for moderated mediation. However, the link between symptoms and negative affect was moderated by perceptions of risk. Whether smokers experience a family member's lung cancer as a TM is influenced by multiple interrelated cognitive and affective factors that warrant further exploration. Clearer understanding of these factors could inform how to re-invigorate and sustain this motivation to promote concrete actions toward smoking cessation. Copyright © 2015 John Wiley & Sons, Ltd.

A proportion of classical Hodgkin lymphoma (HL) is believed to be causally related to infection with the ubiquitous lymphotropic EBV. The determining factors for development of EBV-related HL remain poorly understood, but likely involve immunological control of the viral infection. Accordingly, markers of the HLA class I region have been associated with risk of EBV-related HL. To study the host genetic component of EBV-related HL further, we investigated the lymphoma's association with HLA-A*01 and HLA-A*02 simultaneously in the setting of infectious mononucleosis (IM), a risk factor for EBV-related HL, in a case-series analysis including 278 EBV-related and 656 EBV-unrelated cases of HL. By logistic regression, HLA-A*01 alleles [odds ratio (OR) per allele, 2.15; 95% CI, 1.60–2.88] were associated with increased and HLA-A*02 alleles (OR per allele, 0.70; 95% CI, 0.51–0.97) with decreased risk of EBV-related HL. These allele-specific associations corresponded to nearly 10-fold variation in risk of EBV-related HL between HLA-A*01 and HLA-A*02 homozygotes. History of IM was also associated with risk of EBV-related HL (OR, 3.40; 95% CI, 1.74–6.66). The association between history of IM and EBV-related HL was not seen in the presence of HLA-A*02 because this allele appeared to neutralize the effect of IM on EBV-related HL risk. Our findings suggest that HLA class I-restricted EBV-specific cytotoxic T-cell responses and events in the early immune response to EBV infection in IM play critical roles in the pathogenesis of EBV-related HL.

Relational coordination promotes quality of chronic care delivery in Dutch disease-management programs.

Previous studies have shown that relational coordination is positively associated with the delivery of hospital care, acute care, emergency care, trauma care, and nursing home care. The effect of relational coordination in primary care settings, such as disease-management programs, remains unknown. This study examined relational coordination between general practitioners and other professionals in disease-management programs and assessed the impact of relational coordination on the delivery of chronic illness care. Professionals (n = 188; response rate = 57%) in 19 disease-management programs located throughout the Netherlands completed surveys that assessed relational coordination and chronic care delivery. We used a cross-sectional study design. Our study demonstrated that the delivery of chronic illness care was positively related to relational coordination. We found positive relationships with community linkages (r = .210, p < .01), self-management support (r = .217, p < .01), decision support (r = .190, p < .01), delivery system design (r = .278, p < .001), and clinical information systems (r = .193, p < .01). Organization of the health delivery system was not significantly related to relational coordination. The regression analyses showed that even after controlling for all background variables, relational coordination still significantly affected chronic care delivery (β = .212, p ≤ .01). As expected, our findings showed a lower degree of relational coordination among general practitioners than between general practitioners and other core disease-management team members: practice nurses (M = 2.69 vs. 3.73; p < .001), dieticians (M = 2.69 vs. 3.07; p < .01), physical therapists (M = 2.69 vs. 3.06; p < .01), medical specialists (M = 2.69 vs. 3.16; p < .01), and nurse practitioners (M = 2.69 vs. 3.19; p < .001). The enhancement of relational coordination among core disease-management professionals with different disciplines is expected to improve chronic illness care delivery.

Culturally related stress, hopelessness, and vulnerability to depressive symptoms and suicidal ideation in emerging adulthood.

Culturally related experiences are seldom considered in assessing risk for suicidal behavior among emerging adults, despite racial/ethnic differences in suicide attempts. The present study examined the impact of culturally related stressors on hopelessness, symptoms of depression, and suicidal ideation-well-known predictors of suicidal behavior-among emerging adults over time, and whether hopelessness would mediate the relation between culturally related stressors and both depression and ideation. An ethnically diverse sample of 143 emerging adults, ages 18 to 25, completed self-report measures of acculturative stress, perceived discrimination, and depressive symptoms at 1 time point, and self-report measures of ethnic identity, hopelessness, depressive symptoms, and suicidal ideation 2 to 3years later. Higher baseline acculturative stress and perceived discrimination predicted hopelessness, but not symptoms of depression, when entered simultaneously into a regression analysis. However, there was an indirect relation between these culturally related stressors and depressive symptoms through hopelessness. There was also a direct relation between acculturative stress at baseline and suicidal ideation at follow-up, and hopelessness mediated this relation. However, the indirect relations between culturally related stressors and depression and suicidal ideation through hopelessness were only present at low levels of ethnic identity, but not at average or high levels of ethnic identity. Acculturative stress and perceived discrimination may thus increase vulnerability to depression and suicidal ideation to the extent that they increase hopelessness, but a strong ethnic identity may buffer against this relation. This study highlights the need for incorporating culturally related experiences in assessing risk for suicidal ideation and behavior, particularly among emerging adults from diverse backgrounds.

Beyond Cue Reactivity: Non-Drug-Related Motivationally Relevant Stimuli Are Necessary to Understand Reactivity to Drug-Related Cues.

Neurobiological models of addiction posit that drug use can alter reward processes in two ways: (1) by increasing the motivational relevance of drugs and drug-related cues and (2) by reducing the motivational relevance of non-drug-related rewards. Here, we discuss the results from a series of neuroimaging studies in which we assessed the extent to which these hypotheses apply to nicotine dependence. In these studies, we recorded smokers’ and nonsmokers’ brain responses to a wide array of motivationally relevant visual stimuli that included pleasant, unpleasant, cigarette-related, and neutral images. Based on these findings, we highlight the flaws of the traditional cue reactivity paradigm and we conclude that responses to non-drug-related motivationally relevant stimuli should be used to appropriately gauge the motivational relevance of cigarette-related cues and to identify smokers attributing higher motivational relevance to drug-related cues than to non-drug-related rewards. Identifying these individuals is clinically relevant as they achieve lower rates of long-term smoking abstinence when attempting to quit. Finally, we show how this approach may be extended beyond nicotine dependence to inform theoretical and clinical research in the study of obesity. The cue reactivity paradigm (ie, comparing responses evoked by drug-related cues to those evoked by neutral cues) cannot provide conclusive information about the motivational relevance of drug-related cues. Responses to non-drug-related motivationally relevant stimuli should be used to appropriately gauge the level of motivational relevance that substance-dependent individuals attribute to drug-related cues. © The Author 2017.

To describe patterns of drug- and alcohol-related hospitalizations among persons exposed to the 2001 World Trade Center (WTC) terrorist attacks and to assess whether 9/11-related exposures or post-9/11 post-traumatic stress disorder (PTSD) were associated with increased odds of hospitalization. Data for adult enrollees in the WTC Health Registry, a prospective cohort study, were linked to New York State (NYS) administrative hospitalization data to identify alcohol- and drug-related hospitalizations from enrollment to December 31, 2010. Logistic regression was used to analyze the associations between substance use-related hospitalization, 9/11-related exposure and PTSD. Of 41,176 NYS resident enrollees, we identified 626 (1.5%) who had at least one alcohol- or drug-related hospitalization; 53.4% (n = 591) of these hospitalizations were for alcohol only diagnoses and 46.6% (n = 515) were drug-related. Witnessing ≥3 traumatic events on 9/11 was significantly associated with having a drug-related hospitalization (AOR 1.4, 95% CI = [1.1, 1.9]). PTSD was significantly associated with both having a drug-related hospitalization as well as an alcohol only-related hospitalization. (AOR 2.6, 95% CI = [2.0, 3.3], AOR 1.8, 95% CI = [1.4, 2.3], respectively). Witnessing traumatic events and having PTSD were independently associated with substance use-related hospitalizations. Targeting people who witnessed traumatic events on 9/11 and/or who have PTSD for substance use- treatment could reduce alcohol and drug-related hospitalizations connected to 9/11.

A neuroradiologist's activity includes many tasks beyond interpreting relative value unit-generating imaging studies. Our aim was to test a simple method to record and quantify the non-relative value unit-generating clinical activity represented by consults and clinical conferences, including tumor boards. Four full-time neuroradiologists, working an average of 50% clinical and 50% academic activity, systematically recorded all the non-relative value unit-generating consults and conferences in which they were involved during 3 months by using a simple, Web-based, computer-based application accessible from smartphones, tablets, or computers. The number and type of imaging studies they interpreted during the same period and the associated relative value units were extracted from our billing system. During 3 months, the 4 neuroradiologists working an average of 50% clinical activity interpreted 4241 relative value unit-generating imaging studies, representing 8152 work relative value units. During the same period, they recorded 792 non-relative value unit-generating study reviews as part of consults and conferences (not including reading room consults), representing 19% of the interpreted relative value unit-generating imaging studies. We propose a simple Web-based smartphone app to record and quantify non-relative value unit-generating activities including consults, clinical conferences, and tumor boards. The quantification of non-relative value unit-generating activities is paramount in this time of a paradigm shift from volume to value. It also represents an important tool for determining staffing levels, which cannot be performed on the basis of relative value unit only, considering the importance of time spent by radiologists on non-relative value unit-generating activities. It may also influence payment models from medical centers to radiology departments or practices. © 2016 by American Journal of Neuroradiology.

A path model of different forms of impulsivity with externalizing and internalizing psychopathology: Towards greater specificity.

A growing empirical literature indicates that emotion-related impulsivity (compared to impulsivity that is unrelated to emotion) is particularly relevant for understanding a broad range of psychopathologies. Recent work, however, has differentiated two forms of emotion-related impulsivity: A factor termed Pervasive Influence of Feelings captures tendencies for emotions (mostly negative emotions) to quickly shape thoughts, and a factor termed Feelings Trigger Action captures tendencies for positive and negative emotions to quickly and reflexively shape behaviour and speech. This study used path modelling to consider links from emotion-related and non-emotion-related impulsivity to a broad range of psychopathologies. Undergraduates completed self-report measures of impulsivity, depression, anxiety, aggression, and substance use symptoms. A path model (N = 261) indicated specificity of these forms of impulsivity. Pervasive Influence of Feelings was related to anxiety and depression, whereas Feelings Trigger Action and non-emotion-related impulsivity were related to aggression and substance use. The findings of this study suggest that emotion-relevant impulsivity could be a potentially important treatment target for a set of psychopathologies. Recent work has differentiated two forms of emotion-related impulsivity. This study tests a multivariate path model linking emotion-related and non-emotion-related impulsivity with multiple forms of psychopathology. Impulsive thoughts in response to negative emotions were related to anxiety and depression. Impulsive actions in response to emotions were related to aggression and substance use, as did non-emotion-related impulsivity. The study was limited by the reliance on self-report measures of impulsivity and psychopathology. There is a need for longitudinal work on how these forms of impulsivity predict the onset and course of psychopathology. © 2017 The British Psychological Society.

Springston, Jeffrey K; Weaver Lariscy, Ruth Ann

2005-01-01

This article explores public relations effectiveness in public health institutions. First, the two major elements that comprise public relations effectiveness are discussed: reputation management and stakeholder relations. The factors that define effective reputation management are examined, as are the roles of issues and crisis management in building and maintaining reputation. The article also examines the major facets of stakeholder relations, including an inventory of stakeholder linkages and key audiences, such as the media. Finally, methods of evaluating public relations effectiveness at both the program level and the institutional level are explored.

General tradeoff relations present in nonlocal correlations of bipartite systems are studied, regardless of any specific quantum states and measuring directions. Extensions to multipartite scenarios are possible and very promising. Tsirelson’s bound can be derived out in particular. The close connection with uncertainty relations is also presented and discussed. - Highlights: • Quantum violation of CHSH inequalities is found to satisfy tradeoff relations. • Tsirelson’s bound for quantum mechanics can be directly implied from these tradeoffs. • Tradeoff relations shed new light on uncertainty relations in summation forms.

Monotonically improving approximate answers to relational algebra queries

NASA Technical Reports Server (NTRS)

Smith, Kenneth P.; Liu, J. W. S.

1989-01-01

We present here a query processing method that produces approximate answers to queries posed in standard relational algebra. This method is monotone in the sense that the accuracy of the approximate result improves with the amount of time spent producing the result. This strategy enables us to trade the time to produce the result for the accuracy of the result. An approximate relational model that characterizes appromimate relations and a partial order for comparing them is developed. Relational operators which operate on and return approximate relations are defined.

Relational learning and transitive expression in aging and amnesia

ABSTRACT Aging has been associated with a decline in relational memory, which is critically supported by the hippocampus. By adapting the transitivity paradigm (Bunsey and Eichenbaum (1996) Nature 379:255‐257), which traditionally has been used in nonhuman animal research, this work examined the extent to which aging is accompanied by deficits in relational learning and flexible expression of relational information. Older adults' performance was additionally contrasted with that of amnesic case DA to understand the critical contributions of the medial temporal lobe, and specifically, the hippocampus, which endures structural and functional changes in healthy aging. Participants were required to select the correct choice item (B versus Y) based on the presented sample item (e.g., A). Pairwise relations must be learned (A‐>B, B‐>C, C‐>D) so that ultimately, the correct relations can be inferred when presented with a novel probe item (A‐>C?Z?). Participants completed four conditions of transitivity that varied in terms of the degree to which the stimuli and the relations among them were known pre‐experimentally. Younger adults, older adults, and DA performed similarly when the condition employed all pre‐experimentally known, semantic, relations. Older adults and DA were less accurate than younger adults when all to‐be‐learned relations were arbitrary. However, accuracy improved for older adults when they could use pre‐experimentally known pairwise relations to express understanding of arbitrary relations as indexed through inference judgments. DA could not learn arbitrary relations nor use existing knowledge to support novel inferences. These results suggest that while aging has often been associated with an emerging decline in hippocampal function, prior knowledge can be used to support novel inferences. However, in case DA, significant damage to the hippocampus likely impaired his ability to learn novel relations, while additional damage to ventromedial prefrontal and anterior temporal regions may have resulted in an inability to use prior knowledge to flexibly express indirect relational knowledge. © 2015 The Authors Hippocampus Published by Wiley Periodicals, Inc.

To identify the main types of HIV cure-related strategies and examine possible risks (and benefits) associated with participating in HIV cure-related research studies. We undertook a scoping review to first map out the landscape of HIV cure-related research and then examined the risks and potential benefits associated with participating in HIV cure research. Given the early stage of many HIV cure-related studies, we used proxy literatures from non-cure HIV research and cancer research in order to anticipate possible motivators and deterrents of participation in HIV cure-related studies. We discussed four main categories of HIV cure-related research: (1) early antiretroviral treatment (ART); (2) latency-reversing agents (LRAs); (3) therapeutic vaccinations and immune-based therapies (IBT); and (4) stem-cell transplantation and gene therapy. At this juncture, these categories of HIV cure-related research have substantial individual risks and negligible individual and clinical benefits. Non-cure HIV research (including HIV prevention and treatment) and cancer research have empirical similarities (and differences) to HIV cure research and may provide an opportunity to anticipate ethical and logistical challenges associated with HIV cure-related research participation and decision-making. Learning from the cancer field, a strong foundation of patient-participant and clinician-researcher trust will need to be established to facilitate recruitment of participants into HIV cure-related studies. Further empirical social science and ethics research will be necessary to inform clinical HIV cure-related research. The study of participation in HIV cure-related research can gain insights from proxy fields by incorporating study elements to clearly explain motivators and deterrents to participation and to inform the implementation of HIV cure-related studies. Study-specific contexts from the reviewed literature further demonstrate the importance of various types of research to assess factors affecting participation in HIV cure-related research, including adequate formative and ethics research.

The purpose of the study was to compare tubing-related injuries to wakeboarding- and water skiing-related injuries. Data was collected from the 2000-2007 National Electronic Injury Surveillance Survey for 1,761 individuals seeking care at an emergency department due to a tubing-, wakeboarding, or water skiing-related injury. Data included patient age and sex, as well as injury characteristics including body region injured (i.e., head and neck, trunk, shoulder and upper extremity, and hip and lower extremity) and diagnosis of injury (e.g., contusion, laceration, or fracture). Case narratives were reviewed to ensure that a tubing-, wakeboarding-, or water skiing-related injury occurred while the individual was being towed behind a boat. Severe injury (defined as an injury resulting in the individual being hospitalized, transferred, held for observation) was compared among the groups using logistic regression. Wakeboard- and tubing-related injuries more commonly involved the head and neck, while water skiing- related injuries were likely to involve the hip and lower extremity. Tubing-related injuries, compared to water skiing-related injuries, were more likely to be severe (OR 2.31, 95% CI 1.23-4. 33). Like wakeboarding and water skiing, tubing has inherent risks that must be understood by the participant. While tubing is generally considered a safer alternative to wakeboarding and water skiing, the results of the current study suggest otherwise. Both the number and severity of tubing- related injuries could be prevented through means such as advocating the use of protective wear such as helmets while riding a tube or having recommended safe towing speeds prominently placed on inner tubes. Key pointsIncrease annual injury rate trend in wakeboard injuries.Wakeboard- and tubing-related injuries more often to head and neck, waterskiing-related injuries more often to hip and lower extremity.Tubing-related injuries over 2-times as likely to be severe compared to waterskiing-related injuries.

Family refusal to organ donation of a deceased relative represents one of the most important barriers to organ transplantation. Although a large literature about family decisions has amassed, the existing evidence needs further integration and structuring. This study seeks to analyse relationships between bereaved relatives' decisions and a wide range of factors that converge in the family decision process, including interactions and complex relationship patterns, and taking psychosocial theoretical frameworks as reference to conceptualize empirical findings. This observational study examined 16 Spanish hospitals during a 36-month period. Transplant coordination teams collected data of 421 cases of family decision processes about donation (338 donations/83 refusals) through a previously validated instrument. Indicators of the following factors were collected: deceased's characteristics; circumstances of death; bereaved relatives' characteristics, beliefs, and expressions; behaviour of health and coordination staff; and family's emotional responses. Three global hypotheses related to bivariate and multivariate relations of factors with family decisions and relationships/interactions among factors were tested. Relatives' beliefs about the deceased's wishes concerning donation are the strongest predictor of family decisions. However, family decisions are also related to the deceased's characteristics, relatives' characteristics, satisfaction with medical attention, satisfaction with personal treatment and relatives' emotional responses, and other factors. Relatives' emotional reactions are related to satisfaction with health-staff interventions and condition family decision, even if deceased's will concerning donation is known and positive. Relatives' beliefs about deceased's wishes concerning donation vary as a function of deceased's characteristics and according to relatives' characteristics. Understanding of family decisions underlying organ donation may greatly benefit from a more complex, integrated, and theoretically based approach. Educational efforts should stress the need to register or simply communicate own willingness to donate organs. However, an adequate training and performance of the health-staff involved in the organ donation process may generate substantive differences in consent rates. Copyright © 2018 Elsevier Ltd.

Background Investigating the factors related to suicide is crucial for suicide prevention. Psychiatric disorders, gender, socioeconomic status, and catastrophic illnesses are associated with increased risk of suicide. Most studies have typically focused on the separate influences of physiological or psychological factors on suicide-related behaviors, and have rarely used national data records to examine and compare the effects of major physical illnesses, psychiatric disorders, and socioeconomic status on the risk of suicide-related behaviors. Objectives To identify the characteristics of people who exhibited suicide-related behaviors and the multiple factors associated with repeated suicide-related behaviors and deaths by suicide by examining national data records. Design This is a cohort study of Taiwan’s national data records of hospitalized patients with suicide-related behaviors from January 1, 1997, to December 31, 2010. Participants The study population included all people in Taiwan who were hospitalized with a code indicating suicide or self-inflicted injury (E950–E959) according to the International Classification of Disease, Ninth Revision, Clinical Modification. Results Self-poisoning was the most common method of self-inflicted injury among hospitalized patients with suicide-related behaviors who used a single method. Those who were female, had been hospitalized for suicide-related behaviors at a younger age, had a low income, had a psychiatric disorder (i.e., personality disorder, major depressive disorder, bipolar disorder, schizophrenia, alcohol-related disorder, or adjustment disorder), had a catastrophic illness, or had been hospitalized for suicide-related behaviors that involved two methods of self-inflicted injury had a higher risk of hospitalization for repeated suicide-related behaviors. Those who were male, had been hospitalized for suicide-related behaviors at an older age, had low income, had schizophrenia, showed repeated suicide-related behaviors, had a catastrophic illness, or had adopted a single lethal method had an increased risk of death by suicide. Conclusions High-risk factors should be considered when devising suicide-prevention strategies. PMID:26900930

Correlation analysis of the optics of progressive addition lenses.

Sheedy, James E

To investigate the relations between selected key optical parameters and the sizes of the clear viewing areas of progressive addition lenses (PALs). The optics of 28 PALs (plano with +2.00 D add) currently on the market were measured with a Rotlex Class Plus lens analyzer. Horizontal cross sections were analyzed in 1 mm vertical steps with respect to the fitting cross. Distance, intermediate, and near viewing zone widths and areas were calculated from the measurements. The maximum amount of unwanted astigmatism, minimum zone width (0.50 DC limit), and maximum power rate in the corridor were also recorded for each lens. Correlation coefficients were determined for all relations. Each of the three viewing zone areas had a significant negative relation with the other (r of -0.4 to -0.8), indicating design tradeoff. Maximum power rate was significantly related to minimum zone width (r = -0.695), which was significantly related to maximum astigmatism (r = -0.616), but there was not a significant relation between maximum power rate and maximum astigmatism. Higher power rates and narrower minimum zones were significantly related to smaller intermediate and larger near zones (r = 0.4 to 0.9). Maximum astigmatism was related to distance zone width (r = 0.42) and to intermediate zone size (r = -0.4 to -0.56), but not significantly related to near viewing zone. Power rate and astigmatism each vary relatively uniformly across each lens. The fundamental relation appears to be between power rate and zone width, each of which is highly related to sizes of the intermediate and near viewing zones. The maximum amount of astigmatism is related to zone width, but not to maximum power rate. The amount of astigmatism is unrelated to the size of the near zone. The pattern of correlations between the optical and viewing zone parameters help identify the underlying optical relations of PALs.

Work-related anxiety and depression are frequent work-related mental health problems. In this study the relationship between workplace violence and work-related anxiety and/or depression among Korean employees was evaluated. Data were obtained from the Korean Working Condition Survey of 2006. Participants were 9,094 Korean workers aged 15-64 yr. Multiple logistic regression using SAS version 9.1 was used. The incidence of work-related anxiety, work-related depression and workplace violence were 4.5%, 3.5%, and 1.8% respectively. When personal and occupational risk factors were adjusted, workplace violence was significantly associated with work-related anxiety and depression (OR for anxiety: 4.07, CI: 2.62-6.34; OR for depression: 4.60, CI: 2.92-7.25). Work-related anxiety was significantly related to type of employment, working period at present workplace, work time, shift work, job demand, and social support from superiors. Factors influencing work-related depression were gender, education, alcohol consumption, company size, type of employment, working period at present workplace, work time, shift work, and job demand. To promote psychological health in workers there is a need to develop work-related anxiety and depression prevention programs and to decrease in workplace violence. In developing these programs, consideration should be given to personal factors, working conditions, and psychosocial working environments.

The relationship between HIV-related stigma and health-related quality of life (HRQoL) among children living with HIV infection is unknown. The objectives of this study were to describe HIV-related stigma and HRQoL among children with perinatal HIV living in Sweden, and to investigate the relationship between these two factors in the same infection group. In a cross-sectional nationwide survey, HIV-related stigma was measured with the 8-item HIV Stigma Scale for Children. HRQoL was measured with the 37-item DISABKIDS Chronic Generic Module. Structural equation modeling was used to explore the relationship between HIV-related stigma and HRQoL. Fifty-eight children participated, age 9-18 years (mean = 13.9). The HIV stigma general scale showed a mean score of 17.6 (SD = 5.0; possible range 8-32). DISABKIDS Chronic Generic Module general scale showed a mean score of 80.7 (SD = 14.1; possible range 0-100). HIV-related stigma was negatively associated with HRQoL (standardized β = -0.790, p = .017). The results indicate that children's concerns related to disclosure of their HIV infection seem to be common (i.e. 75% agreed) which, together with the negative association between ratings of HIV-relatively stigma and HRQoL, might indicate that disclosure concerns would be a relevant target for interventions to decrease HIV-related stigma and increase HRQoL.

Experiences of physical and relational victimization in children with ADHD: The role of social problems and aggression.

McQuade, Julia D; Breslend, Nicole L; Groff, Destin

2018-04-16

The social risk factors for physical and relational peer victimization were examined within a mixed-gender sample of children with and without attention-deficit/hyperactivity disorder (ADHD). Participants were 124 children (ages 8-12 years; 48% boys), with 47% exhibiting sub-clinical or clinical elevations in ADHD symptoms. ADHD and oppositional defiant disorder (ODD) symptom counts were assessed based on parent- and teacher-reports; parents rated children's social problems and teachers rated children's use of physical and relational aggression and experiences of physical and relational victimization. A multiple mediator model was used to test whether there were indirect effects of ADHD or ODD symptoms on physical and relational victimization through social problems, physical aggression, or relational aggression. At the bivariate level, ADHD and ODD symptoms were both significantly associated with higher rates of physical and relational victimization. In the mediational model, there were significant indirect effects of ADHD symptoms on relational victimization via social problems, of ODD on relational victimization via relational aggression, and of ODD symptoms on physical victimization via physical aggression. Results suggest that there are distinct risk factors implicated in the physical and relational victimization of youth with ADHD and that the co-occurrence of ODD symptoms is important to assess. Clinical implications for addressing victimization in children with ADHD are discussed. © 2018 Wiley Periodicals, Inc.

Impact of action primes on implicit processing of thematic and functional similarity relations: evidence from eye-tracking.

Pluciennicka, Ewa; Wamain, Yannick; Coello, Yann; Kalénine, Solène

2016-07-01

The aim of this study was to specify the role of action representations in thematic and functional similarity relations between manipulable artifact objects. Recent behavioral and neurophysiological evidence indicates that while they are all relevant for manipulable artifact concepts, semantic relations based on thematic (e.g., saw-wood), specific function similarity (e.g., saw-axe), and general function similarity (e.g., saw-knife) are differently processed, and may relate to different levels of action representation. Point-light displays of object-related actions previously encoded at the gesture level (e.g., "sawing") or at the higher level of action representation (e.g., "cutting") were used as primes before participants identified target objects (e.g., saw) among semantically related and unrelated distractors (e.g., wood, feather, piano). Analysis of eye movements on the different objects during target identification informed about the amplitude and the timing of implicit activation of the different semantic relations. Results showed that action prime encoding impacted the processing of thematic relations, but not that of functional similarity relations. Semantic competition with thematic distractors was greater and earlier following action primes encoded at the gesture level compared to action primes encoded at higher level. As a whole, these findings highlight the direct influence of action representations on thematic relation processing, and suggest that thematic relations involve gesture-level representations rather than intention-level representations.

Extraction of a group-pair relation: problem-solving relation from web-board documents.

Pechsiri, Chaveevan; Piriyakul, Rapepun

2016-01-01

This paper aims to extract a group-pair relation as a Problem-Solving relation, for example a DiseaseSymptom-Treatment relation and a CarProblem-Repair relation, between two event-explanation groups, a problem-concept group as a symptom/CarProblem-concept group and a solving-concept group as a treatment-concept/repair concept group from hospital-web-board and car-repair-guru-web-board documents. The Problem-Solving relation (particularly Symptom-Treatment relation) including the graphical representation benefits non-professional persons by supporting knowledge of primarily solving problems. The research contains three problems: how to identify an EDU (an Elementary Discourse Unit, which is a simple sentence) with the event concept of either a problem or a solution; how to determine a problem-concept EDU boundary and a solving-concept EDU boundary as two event-explanation groups, and how to determine the Problem-Solving relation between these two event-explanation groups. Therefore, we apply word co-occurrence to identify a problem-concept EDU and a solving-concept EDU, and machine-learning techniques to solve a problem-concept EDU boundary and a solving-concept EDU boundary. We propose using k-mean and Naïve Bayes to determine the Problem-Solving relation between the two event-explanation groups involved with clustering features. In contrast to previous works, the proposed approach enables group-pair relation extraction with high accuracy.

Posttraumatic stress (PTS) symptoms are associated with alcohol-related consequences, but there is a need to understand mediators that may help explain the reasons for this relationship. Individuals with PTS may experience elevated craving and alcohol reward value (demand), which may contribute to risk for alcohol-related consequences. We examined relationships between PTS status, craving, alcohol demand, and alcohol-related consequences in PTS-positive (n = 64) and PTS-negative (n = 200) college students (M age = 21.7; 77% women; 54% Caucasian; 34% African American) who endorsed past-month alcohol use. We tested craving and alcohol demand as mediators of the relation between PTS status and alcohol-related consequences. Craving (B = .04, SE = .02, 95% CI [.01, .10]), demand intensity (B = .02, SE = .02, 95% CI [.001, .07]), and demand elasticity (B = .05, SE = .03, 95% CI [.006, .12]) significantly mediated the association between PTS symptoms and alcohol-related consequences. Craving remained a significant mediator in a multiple mediators model (B = .08, SE = .04, 95% CI [.03, .19]). Craving and alcohol demand may partially explain the relation between PTS status and alcohol-related consequences. Craving may be especially salient for individuals with PTS symptoms, as it may lead to more severe alcohol-related consequences even in the absence of elevated alcohol consumption.

To assess the accuracy of relatives' recollections of patients' terminal illness 71 out of 77 caring relatives were re-interviewed about 4 months after they and the patients had given regular interviews throughout care. Current and retrospective ratings of problems and feelings have been compared for agreement, using the kappa index. Several volunteered symptoms showed poor agreement, notably pain, anorexia and depression (kappa = 0.03-0.21), but vomiting, dyspnoea and immobility ratings agreed moderately well (kappa = 0.43-0.68). Current ratings from patients' and relatives' were always in better agreement with each other than with the relatives retrospective ratings. Bias sometimes altered apparent prevalence; pain was described as more severe in retrospect, but weakness, malaise, depression and relatives' stress were under-rated later. Ratings of "discomfort only" became less common for all symptoms retrospectively. The regular current assessments of patients' and relatives' emotional state also agreed only slightly with relatives' follow-up accounts of depression but somewhat better for anxiety. Patients stated knowledge of diagnosis, awareness and acceptance of dying matched the relatives' retrospective assessments moderately well (kappa = 0.70, 0.50 and 0.41). This study and other available evidence indicate that relatives' retrospective reports of terminal illness, measured against current ratings, are moderately reliable for some items but can vary or be potentially misleading over other aspects, including pain. This could affect evaluations of care.

We investigated whether social relations buffer the effect of neighborhood deprivation on mental and physical health-related quality of life. Baseline data from the LifeLines Cohort Study (N=68,111) and a neighborhood deprivation index were used to perform mixed effect linear regression analyses. Results showed that fewer personal contacts (b, 95%CI: -0.88(-1.08;-0.67)) and lower social need fulfillment (-4.52(-4.67;-4.36)) are associated with lower mental health-related quality of life. Higher neighborhood deprivation was also associated with lower mental health related quality of life (-0.18(-0.24;-0.11)), but only for those with few personal contacts or low social need fulfillment. Our results suggest that social relations buffer the effect of neighborhood deprivation on mental health-related quality of life. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Durocher, Evelyne; Kinsella, Elizabeth Anne; McCorquodale, Lisa; Phelan, Shanon

2016-09-03

Ethical tensions arise daily in health care practice and are frequently related to health care system structures or policies. Collective case study methodology was adopted to examine ethical tensions reported by occupational therapists practicing in different settings in Southwestern Ontario, Canada. Inductive analysis involving multiple layers of coding was conducted. This article focuses on tensions related to systemic constraints. Participants reported ethical tensions related to balancing client priorities with those of health care services. Four themes related to systemic constraints were identified including imposed practices, ineffective processes, resource limitations, and lack of services. Therapists' aims could be seen to align with an "ethic of care" and were seen to be in tension in light of systemic constraints. The findings raise issues related to occupational justice, particularly related to occupational alienation in occupational therapy practice, and open conversations related to neoliberalist health care agendas. © The Author(s) 2016.

ABSTRACT OBJECTIVE To quantify the occurrence of deaths directly associated with urban violence among fatal work-related accidents. METHODS Verbal autopsies were performed with the relatives and coworkers of residents of Campinas, state of São Paulo, Brazil, who died from external causes in 2015. We have also analyzed police reports and reports of the Legal Medical Institute related to these deaths. RESULTS We have identified 82 fatal work-related accidents in Campinas in 2015, of which 25 were murders, 35 were traffic accidents not directly related to work activities, and three were suicides at work. The proportional mortality rate for homicides, traffic accidents, and suicides among fatal work-related accidents was estimated at 30.5%, 42.7%, and 3.7%, respectively. CONCLUSIONS Urban violence accounted for three-fourths of the fatal work-related accidents recorded in the period studied. PMID:29236880

Implicit and explicit measures of sexual orientation attitudes: in group preferences and related behaviors and beliefs among gay and straight men.

2004-05-01

The relations among implicit and explicit measures of sexual orientation attitudes and sexual-orientation-related behavior and beliefs among gay men (Study 1) and straight men (Studies 1 and 2) were explored. Study 1 found relations between implicit and explicit measures of sexual orientation attitudes, large differences between gay and straight men on both implicit and explicit measures, and that these measures predicted sexual-orientation-related behaviors among gay men. Also, only straight men exhibited a negative relation between their attitudes toward homosexuality and heterosexuality. Study 2 found that as straight men held more negative attitudes toward homosexuality, they more strongly endorsed the importance of heterosexual identity and of traditional masculine gender roles. These endorsements mediated the negative relation between their attitudes toward heterosexuality and homosexuality. Implications for assessing attitudes toward sexual orientation and their relations for sexual orientation identity are discussed.

Relations of Inhibition and Emotion-Related Parenting to Young Children's Prosocial and Vicariously Induced Distress Behavior.

Eisenberg, Nancy; Spinrad, Tracy L; Taylor, Zoe E; Liew, Jeffrey

2017-08-31

Children's prosocial behavior and personal distress are likely affected by children's temperament as well as parenting quality. In this study, we examined bidirectional relations from age 30 to 42 months between children's (N = 218) prosocial or self-focused (presumably distressed) reactions to a relative stranger's distress and both supportive emotion-related maternal reactions to children's emotions and children's shyness/inhibition. When controlling for 30-month prosocial behavior and personal distress behavior, maternal supportive (emotion-focused and problem-focused) reactions were positively related to prosocial behavior and marginally negatively related to children's personal distress behaviors and shyness/inhibition at 42 months. Thirty-month personal distress behavior predicted greater shyness/inhibition at 42 months, and 30-month shyness/inhibition was negatively related to prosocial behavior at 30 months. © 2017 The Authors.

Intra- and interpattern relations in letter recognition.

PubMed

Sanocki, T

1991-11-01

Strings of 4 unrelated letters were backward masked at varying durations to examine 3 major issues. (a) One issue concerned relational features. Letters with abnormal relations but normal elements were created by interchanging elements between large and small normal letters. Overall accuracy was higher for letters with normal relations, consistent with the idea that relational features are important in recognition. (b) Interpattern relations were examined by mixing large and small letters within strings. Relative to pure strings, accuracy was reduced, but only for small letters and only when in mixed strings. This effect can be attributed to attentional priority for larger forms over smaller forms, which also explains global precedence with hierarchical forms. (c) Forced-choice alternatives were manipulated in Experiments 2 and 3 to test feature integration theory. Relational information was found to be processed at least as early as feature presence or absence.

Choosing relatives for DNA identification of missing persons.

PubMed

Ge, Jianye; Budowle, Bruce; Chakraborty, Ranajit

2011-01-01

DNA-based analysis is integral to missing person identification cases. When direct references are not available, indirect relative references can be used to identify missing persons by kinship analysis. Generally, more reference relatives render greater accuracy of identification. However, it is costly to type multiple references. Thus, at times, decisions may need to be made on which relatives to type. In this study, pedigrees for 37 common reference scenarios with 13 CODIS STRs were simulated to rank the information content of different combinations of relatives. The results confirm that first-order relatives (parents and fullsibs) are the most preferred relatives to identify missing persons; fullsibs are also informative. Less genetic dependence between references provides a higher on average likelihood ratio. Distant relatives may not be helpful solely by autosomal markers. But lineage-based Y chromosome and mitochondrial DNA markers can increase the likelihood ratio or serve as filters to exclude putative relationships. © 2010 American Academy of Forensic Sciences.

Engineering the object-relation database model in O-Raid

NASA Technical Reports Server (NTRS)

Dewan, Prasun; Vikram, Ashish; Bhargava, Bharat

1989-01-01

Raid is a distributed database system based on the relational model. O-raid is an extension of the Raid system and will support complex data objects. The design of O-Raid is evolutionary and retains all features of relational data base systems and those of a general purpose object-oriented programming language. O-Raid has several novel properties. Objects, classes, and inheritance are supported together with a predicate-base relational query language. O-Raid objects are compatible with C++ objects and may be read and manipulated by a C++ program without any 'impedance mismatch'. Relations and columns within relations may themselves be treated as objects with associated variables and methods. Relations may contain heterogeneous objects, that is, objects of more than one class in a certain column, which can individually evolve by being reclassified. Special facilities are provided to reduce the data search in a relation containing complex objects.

Experience and Sentence Processing: Statistical Learning and Relative Clause Comprehension

PubMed Central

Wells, Justine B.; Christiansen, Morten H.; Race, David S.; Acheson, Daniel J.; MacDonald, Maryellen C.

2009-01-01

Many explanations of the difficulties associated with interpreting object relative clauses appeal to the demands that object relatives make on working memory. MacDonald and Christiansen (2002) pointed to variations in reading experience as a source of differences, arguing that the unique word order of object relatives makes their processing more difficult and more sensitive to the effects of previous experience than the processing of subject relatives. This hypothesis was tested in a large-scale study manipulating reading experiences of adults over several weeks. The group receiving relative clause experience increased reading speeds for object relatives more than for subject relatives, whereas a control experience group did not. The reading time data were compared to performance of a computational model given different amounts of experience. The results support claims for experience-based individual differences and an important role for statistical learning in sentence comprehension processes. PMID:18922516

On the volume-dependence of the index of refraction from the viewpoint of the complex dielectric function and the Kramers-Kronig relation.

PubMed

Rocquefelte, Xavier; Jobic, Stéphane; Whangbo, Myung-Hwan

2006-02-16

How indices of refraction n(omega) of insulating solids are affected by the volume dilution of an optical entity and the mixing of different, noninteracting simple solid components was examined on the basis of the dielectric function epsilon(1)(omega) + iepsilon(2)(omega). For closely related insulating solids with an identical composition and the formula unit volume V, the relation [epsilon(1)(omega) - 1]V = constant was found by combining the relation epsilon(2)(omega)V = constant with the Kramers-Kronig relation. This relation becomes [n(2)(omega) - 1]V = constant for the index of refraction n(omega) determined for the incident light with energy less than the band gap (i.e., h omega < E(g)). For a narrow range of change in the formula unit volume, the latter relation is well approximated by a linear relation between n and 1/V.

Moderating Effects of Relational Interdependence on the Association Between Peer Victimization and Depressive Symptoms.

PubMed

Kawabata, Yoshito; Onishi, Ayako

2017-04-01

This short-term longitudinal study examined the association between relational and physical victimization and subsequent depressive symptoms together with the roles of social cognitive processes (i.e., relational interdependence) and gender in this association. A total of 580 Japanese adolescents in the seventh and eighth grades (52 % girls; age range 12-14) participated in this study across an academic year. Results of structural equation modeling demonstrated that relational and physical victimization, which was assessed via self- and teacher- reports, was concurrently associated with greater depressive symptoms, regardless of the gender of the youth and the level of relational interdependence. Furthermore, after controlling for the stability and co-occurrence between each construct, relational victimization (not physical victimization) was predictive of elevated depressive symptoms only for boys who exhibited relatively higher relational interdependence. The findings are discussed from developmental, gender, and cultural perspectives.

Hostile attribution biases for relationally provocative situations and event-related potentials.

Godleski, Stephanie A; Ostrov, Jamie M; Houston, Rebecca J; Schlienz, Nicolas J

2010-04-01

This exploratory study investigates how hostile attribution biases for relationally provocative situations may be related to neurocognitive processing using the P300 event-related potential. Participants were 112 (45 women) emerging adults enrolled in a large, public university in upstate New York. Participants completed self-report measures on relational aggression and hostile attribution biases and performed an auditory perseveration task to elicit the P300. It was found that hostile attribution biases for relational provocation situations was associated with a larger P300 amplitude above and beyond the role of hostile attribution biases for instrumental situations, relational aggression, and gender. Larger P300 amplitude is interpreted to reflect greater allocation of cognitive resources or enhanced "attending" to salient stimuli. Implications for methodological approaches to studying aggression and hostile attribution biases and for theory are discussed, as well as implications for the fields of developmental psychology and psychopathology.

Faculty perspectives on the inclusion of work-related learning in engineering curricula

NASA Astrophysics Data System (ADS)

Magnell, Marie; Geschwind, Lars; Kolmos, Anette

2017-11-01

The purpose of this paper is to identify faculty perspectives on the integration of work-related issues in engineering education. A mixed methods approach was used to explore faculty attitudes towards work-related learning, to describe activities related to working life that have been introduced into the curriculum and to identify factors that faculty see as important if the amount of work-related learning is to increase. The results show that faculty members are positive about integrating work-related issues into the curriculum. Programmes with more extensive connections to industry offer more integrated activities, such as projects with external actors, and use professional contacts established through research in their teaching. In order to increase work-related learning in engineering curricula, faculty request clear goals and pedagogical tools. Other options to increase work-related learning include offering faculty the opportunity to work outside academia.

Relative Physical Position as an Impression-Management Strategy: Sex Differences in Its Use and Implications.

PubMed

Makhanova, Anastasia; McNulty, James K; Maner, Jon K

2017-05-01

People's physical position relative to others may shape how those others perceive them. The research described here suggests that people use relative physical position to manage impressions by strategically positioning themselves either higher or lower relative to ostensible observers. Five studies supported the prediction that women take and display photographs portraying themselves in a low relative physical position to highlight their youthful features and appear attractive, whereas men take and display photographs portraying themselves in a high relative physical position to highlight their size and appear dominant. The effectiveness of these strategies was confirmed in two studies that measured social perceptions of male and female targets who varied in their relative position. In sum, as do members of other social species, people use relative physical position to manage social impressions, and although these impression-management strategies may have deep ancestral roots, they appear to manifest themselves through a contemporary human modality-photographs.

Double Special Relativity theories are the relativistic theories in which the transformations between inertial observers are characterized by two observer-independent scales of the light speed and the Planck length. We study two main examples of these theories and want to show that these theories are not the new theories of relativity, but only are re-descriptions of Einstein's special relativity in the non-conventional coordinates.

The concepts of relatives of patients suffering from functional psychoses regarding the causes of the illness were investigated using the same methodological approach as with the patients. Relatives, like patients, favoured psychosocial over biological explanations. However, when compared pairwise the concordance between relatives and patients was very low. Some methodological refinements recommended for further research are proposed.

When You Become a Superman: Subliminal Exposure to Death-Related Stimuli Enhances Men's Physical Force.

PubMed

Kawakami, Naoaki; Miura, Emi; Nagai, Masayoshi

2018-01-01

Research based on terror management theory (TMT) has consistently found that reminders to individuals about their mortality engender responses aimed at shoring up faith in their cultural belief system. Previous studies have focused on the critical role that the accessibility of death-related thought plays in these effects. Moreover, it has been shown that these effects occur even when death-related stimuli are presented without awareness, suggesting the unconscious effects of mortality salience. Because one pervasive cultural ideal for men is to be strong, we hypothesized that priming death-related stimuli would lead to increasing physical force for men, but not for women. Building on self-escape mechanisms from TMT, we propose that the mechanism that turns priming of death-related stimuli into physical exertion relies on the co-activation of the self with death-related concepts. To test this hypothesis, we subjected 123 participants to a priming task that enabled us to combine the subliminal priming of death-related words with briefly presented self-related words. Accordingly, three different conditions were created: a (control) condition in which only self-related stimuli were presented, a (priming) condition in which death-related words were subliminally primed but not directly paired with self-related stimuli, and a (priming-plus-self) condition in which death-related words were subliminally primed and immediately linked to self-related stimuli. We recorded handgrip force before and after the manipulations. Results showed that male participants in the priming-plus-self condition had a higher peak force output than the priming and control conditions, while this effect was absent among female participants. These results support the hypothesis that unconscious mortality salience, which is accompanied with self-related stimuli, increases physical force for men but not for women. The gender difference may reflect the cultural belief system, in which individuals are taught that men should be strong. Thus, the unconscious mortality salience produced by exposure to the death-related stimuli motivates need to conform to this internalized cultural standard.

Incorporating the effects of humidity in a mechanistic model of Anopheles gambiae mosquito population dynamics in the Sahel region of Africa

PubMed Central

2013-01-01

Background Low levels of relative humidity are known to decrease the lifespan of mosquitoes. However, most current models of malaria transmission do not account for the effects of relative humidity on mosquito survival. In the Sahel, where relative humidity drops to levels <20% for several months of the year, we expect relative humidity to play a significant role in shaping the seasonal profile of mosquito populations. Here, we present a new formulation for Anopheles gambiae sensu lato (s.l.) mosquito survival as a function of temperature and relative humidity and investigate the effect of humidity on simulated mosquito populations. Methods Using existing observations on relationships between temperature, relative humidity and mosquito longevity, we developed a new equation for mosquito survival as a function of temperature and relative humidity. We collected simultaneous field observations on temperature, wind, relative humidity, and anopheline mosquito populations for two villages from the Sahel region of Africa, which are presented in this paper. We apply this equation to the environmental data and conduct numerical simulations of mosquito populations using the Hydrology, Entomology and Malaria Transmission Simulator (HYDREMATS). Results Relative humidity drops to levels that are uncomfortable for mosquitoes at the end of the rainy season. In one village, Banizoumbou, water pools dried up and interrupted mosquito breeding shortly after the end of the rainy season. In this case, relative humidity had little effect on the mosquito population. However, in the other village, Zindarou, the relatively shallow water table led to water pools that persisted several months beyond the end of the rainy season. In this case, the decrease in mosquito survival due to relative humidity improved the model’s ability to reproduce the seasonal pattern of observed mosquito abundance. Conclusions We proposed a new equation to describe Anopheles gambiae s.l. mosquito survival as a function of temperature and relative humidity. We demonstrated that relative humidity can play a significant role in mosquito population and malaria transmission dynamics. Future modeling work should account for these effects of relative humidity. PMID:23938022

To determine the prevalence and risk factors of symptoms of anxiety, depression, and posttraumatic stress disorder-related symptoms in patients with chronic obstructive pulmonary disease and their relatives after an intensive care unit stay. Prospective multicenter study. Nineteen French intensive care units. One hundred twenty-six patients with chronic obstructive pulmonary disease who survived an intensive care unit stay and 102 relatives. None. Patients and relatives were interviewed at intensive care unit discharge and 90 days later to assess symptoms of anxiety and depression using Hospital Anxiety and Depression Scale (HADS) and posttraumatic stress disorder-related symptoms using the Impact of Event Scale (IES). At intensive care unit discharge, 90% of patients recollected traumatic psychological events in the intensive care unit. At day 90, we were able to conduct telephone interviews with 53 patients and 47 relatives. Hospital Anxiety and Depression Scale scores indicated symptoms of anxiety and depression in 52% and 45.5% of patients at intensive care unit discharge and in 28.3% and 18.9% on day 90, respectively. Corresponding prevalence in relatives were 72.2% and 25.7% at intensive care unit discharge and 40.4% and 14.9% on day 90, respectively. The Impact of Event Scale indicated posttraumatic stress disorder-related symptoms in 20.7% of patients and 29.8% of relatives on day 90. Peritraumatic dissociation assessed using the Peritraumatic Dissociative Experiences Questionnaire was independently associated with posttraumatic stress disorder-related symptoms in the patients and relatives. Previous intensive care unit experience and recollection of bothersome noise in the intensive care unit predicted posttraumatic stress disorder-related symptoms in the patients. Psychiatric symptoms were found to be common in a group of 126 patients with chronic obstructive pulmonary disease who survived an intensive care unit stay and their relatives at intensive care unit discharge and 90 days later. Peritraumatic dissociation at intensive care unit discharge was found to independently predict posttraumatic stress disorder-related symptoms in this sample of patients and relatives.

2006-10-01

The aim of this study was to determine whether there are differences between oral health-related knowledge, attitudes, beliefs and behaviors of children and their parents, and to identify the family-related factors associated with children's poor or good oral health-related behavior. The data were gathered by means of questionnaires from 11-12-year-old schoolchildren and their parents who replied without having knowledge of the answers of the others. Differences between subgroups of children were analyzed by cross-tabulation, and the factors related to children's good or poor oral health-related behavior by logistic regression analyses. Parents of children who reported good oral health-related behavior had better knowledge and more favorable behaviors than those of other parents. Predictors for a child's poor oral health-related behavior were the child's poor knowledge, male gender, the parent's frequent consumption of sweets, and the parent's infrequent use of xylitol gum. When a less strict threshold for the child's poor oral health-related behavior was used, more predictors entered the model: the parent's unfavorable use of fluoride toothpaste; among girls, the parent's lack of knowledge; and among children whose mother's occupation level was high, the parent's infrequent use of xylitol gum. The parents of children whose oral health behavior was favorable were more likely to have a high level occupation and favorable oral health-related behaviors. Oral health-related knowledge of children and their parents seems to be associated with children's oral health-related behavior. Parents' behaviors, but not attitudes, were associated with children's oral health behavior.

An Exploratory Study of Female Psychopathy and Drug-Related Violent Crime.

PubMed

Thomson, Nicholas D

2017-02-01

There is a clear link between drugs and violence, and the extensive burden drug-related violence inflicts on society. However, drug-related violence is largely understudied, especially in female populations. The aim of the present study was to explore whether women convicted of drug-related violent crime differed on individual-level risk factors from women convicted of a nondrug-related violent crime and women convicted of nonviolent crimes. One hundred and twenty-five female inmates were classified using official criminal records. Multinomial logistic regression indicated inmates higher in antisocial psychopathic traits and low level of educational attainment were more likely to be in the drug-related violent crime group. In comparison, inmates higher in callous psychopathic traits were more likely to be in the nondrug-related violent crime group. Using official records of prison misconduct, a secondary aim tested whether prison violence increased the likelihood of being in either of the violent crime groups. Results show inmates who had committed violent misconducts over a 6-month period were more likely to be the nondrug-related violent crime group. Prison violence did not differentiate inmates in the nonviolent crime group from the drug-related violent crime group. These findings are the first to explore the relation between psychopathy and drug-related violent crime, and drug-related violent crime predicting future violent behavior in female criminals. This study demonstrates the heterogeneity in female violent behavior. Furthermore, psychopathy is not only shown to be an important risk factor for violence in women but also highlights that the dimensional construct is essential for understanding context-dependent violence.

We examined the status of the neural network mediating the default mode of brain function, which typically exhibits greater activation during rest than during task, in patients in the early phase of schizophrenia and in young first-degree relatives of persons with schizophrenia. During functional MRI, patients, relatives, and controls alternated between rest and performance of working memory (WM) tasks. As expected, controls exhibited task-related suppression of activation in the default network, including medial prefrontal cortex (MPFC) and posterior cingulate cortex/precuneus. Patients and relatives exhibited significantly reduced task-related suppression in MPFC, and these reductions remained after controlling for performance. Increased task-related MPFC suppression correlated with better WM performance in patients and relatives and with less psychopathology in all 3 groups. For WM task performance, patients and relatives had greater activation in right dorsolateral prefrontal cortex (DLPFC) than controls. During rest and task, patients and relatives exhibited abnormally high functional connectivity within the default network. The magnitudes of default network connectivity during rest and task correlated with psychopathology in the patients. Further, during both rest and task, patients exhibited reduced anticorrelations between MPFC and DLPFC, a region that was hyperactivated by patients and relatives during WM performance. Among patients, the magnitude of MPFC task suppression negatively correlated with default connectivity, suggesting an association between the hyperactivation and hyperconnectivity in schizophrenia. Hyperactivation (reduced task-related suppression) of default regions and hyperconnectivity of the default network may contribute to disturbances of thought in schizophrenia and risk for the illness.

Laboratory studies of alcohol-inexperienced adolescents show that aggression can be primed by alcohol-related stimuli, suggesting that alcohol-related aggression is partly socially learned. Script theory proposes that alcohol-related aggression 'scripts' for social behaviors are culturally-available and learned by individuals. The purpose of the study was to understand the content and origins of alcohol-related aggression scripts learned by adolescents. This qualitative focus group study of 40 adolescents (ages 14-16 years) examined alcohol-related aggression scripts. Participants believed aggression and severe injury to be pervasive when young people drink. Viewed through a biological lens, participants described aggression as an 'instinctive' and 'hard-wired' male trait facilitated by intoxication. As such, alcohol-related aggression was not seen as intended or personally controllable and participants did not see it in moral terms. Females were largely viewed as either bystanders of inter-male aggression or potential victims of male sexual aggression. Participants attributed their views on the frequency and nature of alcohol-related aggression to current affairs and reality television, which they felt portrayed a reality of which they had little experience. The origins of the explicitly biological frameworks that participants used seemed to lie in pre-existing beliefs about the nature of gender differences. Perceptions of the pervasiveness of male alcohol-related aggression, and the consequent failure to view alcohol-related aggression in moral terms, could dispose some young people to alcohol-related aggression. Interventions could target (1) the beliefs that alcohol-related aggression is pervasive and uncontrollable in males, and (2) participants' dysfunctional views of masculinity that underpin those beliefs.

Introduction Prescription opioid pain reliever overdose is a major public health issue in the United States. To characterize the location of drug-related deaths, we examined fatal prescription opioid and illicit drug-related deaths reported in 12 states. Methods Data are from the Substance Abuse and Mental Health Services Administration's Drug Abuse Warning Network (DAWN). Medical examiners or coroners in 12 states (MA, MD, ME, NH, NM, OK, OR, RI, UT, VA, VT, WV) reported details of state-wide drug-related mortality during 2008–2010. DAWN data included location and manner of death, age, race, and drugs involved. Deaths were coded into three categories: prescription opioid-related, illicit drug-related, and cases that involved both a prescription opioid and an illicit drug. Results During a 3-year period, there were 14,091 opioid or illicit drug-related deaths in 12 states. More than half of the prescription opioid-related deaths in all states, except Maryland, occurred at home, rather than in public or in a health care facility. Although it was still the predominant category, lower percentages of illicit drug-related deaths occurred at home. Conclusion Prescription opioid overdoses have increased substantially, and the location of the person at the time of death can have important public health implications for interventions. Practical applications This paper highlights that bystander support can be a critical lifesaving factor in drug related deaths but may be more likely for illicit drug-related deaths than for prescription opioid-related deaths.

Hoarding Disorder (HD), a new diagnostic entity in DSM-5, is associated with substantial functional impairment and family frustration but data from well-characterized samples is lacking. Participants were 37 individuals meeting DSM-5 criteria for HD, 55 relatives of individuals meeting criteria for HD, and comparison groups of 51 self-identified collectors and 25 relatives of collectors. All participants completed a clinician-administered diagnostic interview for HD and an online battery of standardized measures of health, well-being, and impairment. Substantial functional impairment was found for both HD individuals and their relatives. HD relatives reported significantly greater carer burden and accommodation of hoarding behaviors than relatives of collectors. Perceived level of squalor, co-habiting with, and increasing age of the HD individual were significant predictors of carer burden and functional impairment in the relatives. The use of self-identified HD individuals may have produced a bias towards participants with relatively good insight. Subjective biases in self-reported symptoms cannot be ruled out, although the use of informant-report data provided some independent validation. HD is associated with substantial functional impairment for both sufferers and their relatives. The level of carer burden experienced by HD relatives was comparable to or greater than that reported in the literature by relatives of individuals with dementia. The findings indicate that relatives of individuals with HD may benefit from increased support and suggest that it may be beneficial to involve family members in the treatment of HD.

Sex affects the presentation, treatment, and outcomes of abdominal aortic aneurysm (AAA). Although AAAs are less prevalent in women, at least in the general population, women with an AAA have a poorer prognosis in comparison to men. Sex differences in the genetic predisposition for aneurysm disease remain to be established. In this study we investigated the familial risk of AAA for women compared to men. All living AAA patients included in a 2004-2012 prospective database were invited to the multidisciplinary vascular/genetics outpatient clinic between 2009 and 2012 for assessment of family history using detailed questionnaires. AAA risk for male and female relatives was calculated separately and stratified by sex of the AAA patients. Families of 568 AAA patients were investigated and 22.5% of the patients had at least one affected relative. Female relatives had a 2.8-fold and male relatives had a 1.7-fold higher risk than the estimated sex-specific population risk. Relatives of female AAA patients had a higher aneurysm risk than relatives of male patients (9.0 vs 5.9%, p = 0.022), corresponding to 5.5- and 2.0-fold increases in aneurysm risk in the female and male relatives, respectively. The risk for aortic aneurysm in relatives of AAA patients is higher than expected from population risk. The excess risk is highest for the female relatives of AAA patients and for the relatives of female AAA patients. These findings endorse targeted AAA family screening for female and male relatives of all AAA patients.

In the care of hypertension, it is important that health professionals possess available tools that allow evaluating the impairment of the health-related quality of life, according to the severity of hypertension and the risk for cardiovascular events. Among the instruments developed for the assessment of health-related quality of life, there is the Mini-Cuestionario of Calidad de Vida en la Hipertensión Arterial (MINICHAL) recently adapted to the Brazilian culture. To estimate the validity of known groups of the Brazilian version of the MINICHAL regarding the classification of risk for cardiovascular events, symptoms, severity of dyspnea and target-organ damage. Data of 200 hypertensive outpatients concerning sociodemographic and clinical information and health-related quality of life were gathered by consulting the medical charts and the application of the Brazilian version of MINICHAL. The Mann-Whitney test was used to compare health-related quality of life in relation to symptoms and target-organ damage. The Kruskal-Wallis test and ANOVA with ranks transformation were used to compare health-related quality of life in relation to the classification of risk for cardiovascular events and intensity of dyspnea, respectively. The MINICHAL was able to discriminate health-related quality of life in relation to symptoms and kidney damage, but did not discriminate health-related quality of life in relation to the classification of risk for cardiovascular events. The Brazilian version of the MINICHAL is a questionnaire capable of discriminating differences on the health-related quality of life regarding dyspnea, chest pain, palpitation, lipothymy, cephalea and renal damage.

Atomic temporal interval relations in branching time: calculation and application

A practical method of reasoning about intervals in a branching-time model which is dense, unbounded, future-branching, without rejoining branches is presented. The discussion is based on heuristic constraint- propagation techniques using the relation algebra of binary temporal relations among the intervals over the branching-time model. This technique has been applied with success to models of intervals over linear time by Allen and others, and is of cubic-time complexity. To extend it to branding-time models, it is necessary to calculate compositions of the relations; thus, the table of compositions for the 'atomic' relations is computed, enabling the rapid determination of the composition of arbitrary relations, expressed as disjunctions or unions of the atomic relations.

While cigarette smoking is decreasing among young adults, rates of nicotine consumption through other devices, most notably electronic cigarettes, are on the rise. Framed by communication theory of identity, this study examines young adult smokers' experiences with relational others in regard to their smoking. Focus group discussions and individual interviews convened with 20 young adult cigarette and electronic cigarette smokers revealed identity gaps implicating the relational layer of identity, including personal-relational, enacted-relational, and personal-enacted-relational identity gaps. Participants used communicative and behavioral strategies to manage relational discrepancies. The documented identity gaps and management strategies present opportunities for targeted smoking cessation interventions that amplify dissonance created through identity gaps as a motivational tactic.

Using daily diary data to document involvement with infants at 6 – 8 months of age (n = 142) and 6 months later (n = 95), we examined relations between reported childrearing attitudes and resident fathers' relative (as compared to mothers') involvement with children. Fathers' authoritarian views related negatively to their relative involvement on weekdays, and this relation held over time for caregiving and playing activities. Mothers' protective attitudes had concurrent negative associations with fathers' relative weekend involvement. Findings suggest that fathers' authoritarian and mothers' protective attitudes relate to how parenting responsibilities are shared within families and may be detrimental to how much fathers become, or choose to become, directly involved in the care of their infants in comparison to mothers.

Posttraumatic stress disorder and behavioral disorders are related to problems in emotional functioning for young children. Factors related to child functioning are important to understand in order to develop interventions and assess their impact. This study examined clinician and parent reports of child functioning and behavior problems and factors related to each of these outcome variables. Results indicated that parental acceptance was inversely related to child behavior problems. Increased parental supervision of the child was related to high total problems scores. Parental acceptance was positively related to child functioning. Future research is needed to examine relations among interventions to improve parental supervision and interactions with the child and child functioning, in terms of both positive and negative behaviors.

Alcohol-Related Problems and Risk for Suicide among College Students: The Mediating Roles of Belongingness and Burdensomeness

This study examined the relations among alcohol-related problems, perceived burdensomeness, thwarted belongingness, and suicide proneness in undergraduate college students (N = 996). As hypothesized, alcohol-related problems, perceived burdensomeness, and thwarted belongingness were all significantly and positively correlated with suicide proneness. The relation between experiencing alcohol-related problems and suicide proneness was, in part, accounted for by perceived burdensomeness and thwarted belongingness. Additionally, the mediation via perceived burdensomeness was significantly stronger than the mediation via thwarted belongingness. Results suggest that it would be advisable for clinicians to be aware of students’ experiences with alcohol-related problems in conjunction with their levels of burdensomeness and belongingness when assessing for suicide risk PMID:21883409

There is limited knowledge concerning fall-related activity avoidance in people with Parkinson's disease (PD); such knowledge would be of importance for the development of more efficient PD-care and rehabilitation. This study aimed to examine how fall-related activity avoidance relates to a history of self-reported falls/near falls and fear of falling (FOF) as well as to disease severity in people with PD. Data were collected from 251 (61 % men) participants with PD; their median (min-max) age and PD duration were 70 (45-93) and 8 (1-43) years, respectively. A self-administered postal survey preceded a home visit which included observations, clinical tests and interview-administered questionnaires. Fall-related activity avoidance was assessed using the modified Survey of Activities and Fear of Falling in the Elderly (mSAFFE) as well as by using a dichotomous (Yes/No) question. Further dichotomous questions concerned: the presence of FOF and the history (past 6 months) of falls or near falls, followed by stating the number of incidents. Disease severity was assessed according to the Hoehn and Yahr (HY) stages. In the total sample (n = 251), 41 % of the participants reported fall-related activity avoidance; the median mSAFFE score was 22. In relation to a history of fall, the proportions of participants (p < 0.001) that reported fall-related activity avoidance were: non-fallers (30 %), single fallers (50 %) and recurrent fallers, i.e. ≥ 2 falls (57 %). Among those that reported near falls (but no falls), 51 % (26 out of 51) reported fall-related activity avoidance. Of those that reported FOF, 70 % reported fall-related activity avoidance. Fall-related activity avoidance ranged from 24 % in the early PD-stage (HY I) to 74 % in the most severe stages (HY IV-V). Results indicate that fall-related activity avoidance may be related to a history of self-reported falls/near falls, FOF and disease severity in people with PD. Importantly, fall-related activity avoidance is reported among those that do not fall and already in mild PD-stages (HY I-II). Although further studies are needed, our findings indicate that fall-related activity avoidance needs to be addressed early in order to prevent sedentary behavior and participation restrictions.

Background: ARDS may occur after either septic or nonseptic injuries. Sepsis is the major cause of ARDS, but little is known about the differences between sepsis-related and non-sepsis-related ARDS. Methods: A total of 2,786 patients with ARDS-predisposing conditions were enrolled consecutively into a prospective cohort, of which 736 patients developed ARDS. We defined sepsis-related ARDS as ARDS developing in patients with sepsis and non-sepsis-related ARDS as ARDS developing after nonseptic injuries, such as trauma, aspiration, and multiple transfusions. Patients with both septic and nonseptic risks were excluded from analysis. Results: Compared with patients with non-sepsis-related ARDS (n = 62), patients with sepsis-related ARDS (n = 524) were more likely to be women and to have diabetes, less likely to have preceding surgery, and had longer pre-ICU hospital stays and higher APACHE III (Acute Physiology and Chronic Health Evaluation III) scores (median, 78 vs 65, P < .0001). There were no differences in lung injury score, blood pH, Pao2/Fio2 ratio, and Paco2 on ARDS diagnosis. However, patients with sepsis-related ARDS had significantly lower Pao2/Fio2 ratios than patients with non-sepsis-related ARDS patients on ARDS day 3 (P = .018), day 7 (P = .004), and day 14 (P = .004) (repeated-measures analysis, P = .011). Compared with patients with non-sepsis-related ARDS, those with sepsis-related had a higher 60-day mortality (38.2% vs 22.6%; P = .016), a lower successful extubation rate (53.6% vs 72.6%; P = .005), and fewer ICU-free days (P = .0001) and ventilator-free days (P = .003). In multivariate analysis, age, APACHE III score, liver cirrhosis, metastatic cancer, admission serum bilirubin and glucose levels, and treatment with activated protein C were independently associated with 60-day ARDS mortality. After adjustment, sepsis-related ARDS was no longer associated with higher 60-day mortality (hazard ratio, 1.26; 95% CI, 0.71-2.22). Conclusion: Sepsis-related ARDS has a higher overall disease severity, poorer recovery from lung injury, lower successful extubation rate, and higher mortality than non-sepsis-related ARDS. Worse clinical outcomes in sepsis-related ARDS appear to be driven by disease severity and comorbidities. PMID:20507948

Reciprocal Relations between Work-Related Authenticity and Intrinsic Motivation, Work Ability and Depressivity: A Two-Wave Study

2017-01-01

This study investigates the role of context-specific authenticity at work for work-related outcomes (intrinsic motivation, work ability) and depressivity. Furthermore reciprocal relations between work-related authenticity and healthy psychological functioning are investigated. Longitudinal data from 1,243 employees from 63 subsidiaries of a non-profit organization in the social sector were analyzed using multilevel structural equation modeling. Work-related authenticity at T1 predicted work ability and depressivity, but not intrinsic motivation at T2, about 6 months later. Work-related authenticity at T2 was predicted by intrinsic motivation and depressivity, but not by work ability at T1. We conclude that work-related authenticity and healthy psychological functioning are positively reinforcing each other. Thus, enabling employees to be authentic supposedly increases their well-being and is a pivotal opportunity for organizations to foster health and performance-related indicators like work ability and prevent negative health indicators like depressivity. At the same time, authenticity of employees can be fostered through workplace health promotion. PMID:28316581

The Longitudinal Relation Between Academic/Cognitive Skills and Externalizing Behavior Problems in Preschool Children.

2013-08-01

Existing research suggests that there is a relation between academic/cognitive deficits and externalizing behavior in young children, but the direction of this relation is unclear. The present study tested competing models of the relation between academic/cognitive functioning and behavior problems during early childhood. Participants were 221 children (120 boys, 101 girls) who participated in a longitudinal study from age 3 to 6. A reciprocal relation (Model 3) was observed only between inattention and academic achievement; this relation remained controlling for SES and family stress. The relation between inattention and cognitive ability was consistent with Model 1 (cognitive skills predicting later inattention) with controls. For hyperactivity and aggression, there was some support for Model 2 (early behavior predicting later academic/cognitive ability), but this model was no longer supported when controlling for family functioning. These results suggest that the relation between academic achievement/cognitive ability and externalizing problems may be driven primarily by inattention. These results also suggest that this relation is evident early in development, highlighting the need for early assessment and intervention.

A diary study on work-related smartphone use, psychological detachment and exhaustion: examining the role of the perceived segmentation norm.

In this diary study, we examined the associations between daily work-related smartphone use and daily psychological detachment and daily work-related exhaustion within a group of smartphone owners. In addition, we studied the role of the perceived segmentation norm at the workplace as a moderator of the link between work-related smartphone use and detachment. A total of 70 employees using smartphones on initiative of their employer completed a diary questionnaire on 4 successive workdays (N = 268 data points). We hypothesized that work-related smartphone use is negatively related to psychological detachment and that psychological detachment, in turn, is negatively related to work-related exhaustion. Finally, we expected that especially employees who perceive a high segmentation norm at their workplace have difficulties to psychologically detach from work on days that they use their smartphone more intensively. Overall, the results of multilevel analyses supported these hypotheses. The findings emphasize the importance of a clear organizational policy regarding work-related smartphone use outside of work hours. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Local relative density modulates failure and strength in vertically aligned carbon nanotubes.

Micromechanical experiments, image analysis, and theoretical modeling revealed that local failure events and compressive stresses of vertically aligned carbon nanotubes (VACNTs) were uniquely linked to relative density gradients. Edge detection analysis of systematically obtained scanning electron micrographs was used to quantify a microstructural figure-of-merit related to relative local density along VACNT heights. Sequential bottom-to-top buckling and hardening in stress-strain response were observed in samples with smaller relative density at the bottom. When density gradient was insubstantial or reversed, bottom regions always buckled last, and a flat stress plateau was obtained. These findings were consistent with predictions of a 2D material model based on a viscoplastic solid with plastic non-normality and a hardening-softening-hardening plastic flow relation. The hardening slope in compression generated by the model was directly related to the stiffness gradient along the sample height, and hence to the local relative density. These results demonstrate that a microstructural figure-of-merit, the effective relative density, can be used to quantify and predict the mechanical response.
