Interplanetary baseline observations of type 3 solar radio bursts

Simultaneous observations of type III radio bursts using spacecraft separated by several tenths of an AU were made using the solar orbiters HELIOS-A and -B. The burst beginning at 1922 UT on March 28, 1976, was located from the intersection of the source directions measured at each spacecraft, and from the burst arrival time differences. Wide baseline observations give the radial distance of the source at each observing frequency. Consequently, coronal electron densities and exciter velocity were determined directly, without the need to assume a density model as is done with single spacecraft observations. The separation of HELIOS-A and -B also provided the first measurements of burst directivity at low frequencies. For the March 28 burst, the intensity observed from near the source longitude (HELIOS-B) was significantly greater than from 60 W of the source (HELIOS-A)

A model of the local region of the galaxy

A two-component model of the local interstellar medium was developed, based on the Radio Astronomy Explorer (RAE-1) satellite observations of the low frequency (0.2 - 10 MHz) galactic radio background spectrum. The model shows evidence for a thick spiral arm and a thick electron disk of 600 and 1200 pc slab thicknesses, respectively. The temperature difference between the north galactic pole and anticenter directions supports the concept of a local positive thermal gradient away from the galactic plane. A preliminary discussion of the influence of the Razin effect on the model is also presented

The role of violent thinking in violent behaviour; it’s more about thinking than drinking

This article aims to explore and report on violent thinking and alcohol misuse; how these factors may predict self-reported violence. The role of violent thinking in violent behavior is both well established in theoretical models, yet there are few measures that explain this role. One measure that has been identified is the Maudsley Violence Questionnaire (MVQ). This is the first study to explore the use of the MVQ with a general (nonoffender) adult sample, having already been shown to be valid with young people (under 18 years old), adult male offenders, and mentally disordered offenders. This study involved 808 adult participants—569 female and 239 male participants. As figures demonstrate that around half of all violent crime in the United Kingdom is alcohol related, we also explored the role of alcohol misuse. Regression was used to explore how these factors predicted violence. The results demonstrate the important role of violent thinking in violent behavior. The MVQ factor of “Machismo” was the primary factor in regression models for both male and female self-reported violence. The role of alcohol in the regression models differed slightly between the male and female participants, with alcohol misuse involved in male violence. The study supports theoretical models including the role of violent thinking and encourages those hoping to address violence, to consider “Machismo” as a treatment target. The study also provides further validation of the MVQ as a helpful tool for clinicians or researchers who may be interested in “measuring” violent thinking

CBT for people with intellectual disabilities : emerging evidence, cognitive ability and IQ effects

Historically people with intellectual disabilities have not been offered or received cognitive behavioural interventions that have been shown to be effective for mental health and emotional problems experienced by those without such disabilities. This is despite many people with intellectual disabilities having life experiences that potentially result in them having an increased risk to such problems. This paper discusses whether such therapeutic disdain is justified based on the evidence that is available and emerging concerning the application of cognitive behavioural interventions for this population. Issues concerning access to services, the ability of people with intellectual disabilities to engage in and benefit from the cognitive components of CBT, and the effect of cognitive abilities and IQ level on treatment effectiveness are explored in relation to this question

Rotational and Vibrational Dynamics of Interstitial Molecular Hydrogen

The calculation of the hindered roton-phonon energy levels of a hydrogen molecule in a confining potential with different symmetries is systematized for the case when the rotational angular momentum $J$ is a good quantum number. One goal of this program is to interpret the energy-resolved neutron time of flight spectrum previously obtained for H$_{2}$C$_{60}$. This spectrum gives direct information on the energy level spectrum of H$_2$ molecules confined to the octahedral interstitial sites of solid C$_{60}$. We treat this problem of coupled translational and orientational degrees of freedom a) by construction of an effective Hamiltonian to describe the splitting of the manifold of states characterized by a given value of $J$ and having a fixed total number of phonon excitations, b) by numerical solutions of the coupled translation-rotation problem on a discrete mesh of points in position space, and c) by a group theoretical symmetry analysis. Results obtained from these three different approaches are mutually consistent. The results of our calculations explain several hitherto uninterpreted aspects of the experimental observations, but show that a truly satisfactory orientational potential for the interaction of an H$_2$ molecule with a surrounding array of C atoms has not yet been developed.Comment: 53 pages, 9 figures, to appear in Phys.

The "Daily Grind": Work, Commuting, and Their Impact on Political Participation

Past research demonstrates that free time is an important resource for political participation. We investigate whether two central drains on citizens? daily time?working and commuting?impact their level of political participation. The prevailing ?resources? model offers a quantity-focused view where additional time spent working or commuting reduces free time and should each separately decrease participation. We contrast this view to a ?commuter?s strain? hypothesis, which emphasizes time spent in transit as a psychologically onerous burden over and above the workday. Using national survey data, we find that time spent working has no effect on participation, while commuting significantly decreases participation. We incorporate this finding into a comprehensive model of the ?daily grind,? which factors in both socioeconomic status and political interest. Our analysis demonstrates that commuting leads to the greatest loss in political interest for low-income Americans, and that this loss serves as a main mechanism through which commuting erodes political participation

Simulations of Two-Dimensional Melting on the Surface of a Sphere

We have simulated a system of classical particles confined on the surface of a sphere interacting with a repulsive $r^{-12}$ potential. The same system simulated on a plane with periodic boundary conditions has van der Waals loops in pressure-density plots which are usually interpreted as evidence for a first order melting transition, but on the sphere such loops are absent. We also investigated the structure factor and from the width of the first peak as a function of density we can show that the growth of the correlation length is consistent with KTHNY theory. This suggests that simulations of two dimensional melting phenomena are best performed on the surface of a sphere.Comment: 4 eps figure

Women, anger, and aggression an interpretative phenomenological analysis

This study reports a qualitative phenomenological investigation of anger and anger-related aggression in the context of the lives of individual women. Semistructured interviews with five women are analyzed using interpretative phenomenological analysis. This inductive approach aims to capture the richness and complexity of the lived experience of emotional life. In particular, it draws attention to the context-dependent and relational dimension of angry feelings and aggressive behavior. Three analytic themes are presented here: the subjective experience of anger, which includes the perceptual confusion and bodily change felt by the women when angry, crying, and the presence of multiple emotions; the forms and contexts of aggression, paying particular attention to the range of aggressive strategies used; and anger as moral judgment, in particular perceptions of injustice and unfairness. The authors conclude by examining the analytic observations in light of phenomenological thinking

Isotopic and spin selectivity of H_2 adsorbed in bundles of carbon nanotubes

Due to its large surface area and strongly attractive potential, a bundle of carbon nanotubes is an ideal substrate material for gas storage. In addition, adsorption in nanotubes can be exploited in order to separate the components of a mixture. In this paper, we investigate the preferential adsorption of D_2 versus H_2(isotope selectivity) and of ortho versus para(spin selectivity) molecules confined in the one-dimensional grooves and interstitial channels of carbon nanotube bundles. We perform selectivity calculations in the low coverage regime, neglecting interactions between adsorbate molecules. We find substantial spin selectivity for a range of temperatures up to 100 K, and even greater isotope selectivity for an extended range of temperatures,up to 300 K. This isotope selectivity is consistent with recent experimental data, which exhibit a large difference between the isosteric heats of D_2 and H_2 adsorbed in these bundles.Comment: Paper submitted to Phys.Rev.
