Quasiparticle interactions and the Bose-Einstein phase transition

We look at a strongly interacting Bose gas in an attempt to understand the effects upon the physics of the phase transition of the interactions between the higher momentum excitations. At densities an order of magnitude below liquid helium, we find that these interactions are affecting the phase transition in a manner reminiscent of the effects of roton-roton interactions upon the lambda transition. We find singularities in the specific heat and infinite slope at the transition temperature for the superfluid density.     

Assessment of Anger and Aggression in Male Offenders With Developmental Disabilities.

Systematic assessment of anger among people with developmental disabilities has been lacking, especially for hospital inpatients. Reliability and validity of anger self-report psychometric scales were investigated with 129 male patients, mostly forensic. Anger prevalence and its relationship to demographic, cognitive, and personality variables and to hospital assaultive behavior were examined. High internal and intermeasure consistency, and some concurrent validity with staff ratings, were found. Retrospective validity regarding physically assaultive behavior in the hospital was obtained. Hierarchical regressions revealed that patient-reported anger was a significant predictor of assaults postadmission, controlling for age, length of stay, IQ, violence offense history, and personality variables.

Cognitive-behavioral treatment for severe anger in posttraumatic stress disorder.

With a randomized group design, a 12-session anger treatment was evaluated with severely angry Vietnam War veterans suffering combat-related posttraumatic stress disorder (PTSD). Eight participants in anger treatment and 7 in a routine clinical care control condition completed multiple measures of anger control, anger reaction, and anger disposition, as well as measures of anxiety, depression, and PTSD at pre- and posttreatment. Controlling for pretreatment scores, significant effects were found on anger reaction and anger control measures but not on anger disposition or physiological measures. Eighteen-month follow-up (for both completers and dropouts) supported the posttreatment anger control findings. The challenges of treatment research with this refractory population are discussed.

Training of probation counselors for anger problems.

A cognitive-behavioral intervention for anger/aggression problems was extended in a training project for juvenile probation counselors. Five trained counselors were evaluated in comparison with 4 matched controls on self-report and behavioral measures both 2 wks and 2 mo after training. Trained counselors performed with consistently greater proficiency than did controls on measures of problem assessment and intervention.

A virial coefficient analysis of helium adsorption isotherms

A model in which the atoms in the second layer of a monolayer-plus helium film are assumed to form a quasi-two-dimensional gas is used to analyze the isotherm data of Goellner, Daunt, and Lerner for helium on Grafoil. The parameters in the model are determined by a least-squares fit of the model isotherm to the data. These parameters include the second and third virial coefficients of the quasi-two-dimensional gas and the binding energy of the second-layer atoms to the first layer. The empirical values are compared to recent theoretical predictions for the two-dimensional helium gas. The agreement and discrepancies between theoretical and empirical values are discussed. The conclusion is that the second layer (at low densities) can be described as an imperfect two-dimensional gas with perhaps some modification of the interatomic potential due to substrate effects.     

A stress inoculation approach to anger management in the training of law enforcement officers

Consultation with law enforcement personnel in the area of conflict-management has typically been concerned with interpersonal rather than intrapersonal conflict. An approach to anger management that is based on cognitive self-control techniques is described as it has been used in the training of police officers. The approach follows a procedure called "stress inoculation" that has been applied to anxiety and pain (Meichenbaum, 1975). Data are presented on the anger experiences of policemen, and suggestions are offered for the selection of police candidates regarding their proneness for provocation.     

Stress inoculation: A cognitive therapy for anger and its application to a case of depression.

Clinical interventions for anger disorders have been scarcely addressed in both theory and research in psychotherapy. The development of a cognitive behavior therapy approach to anger management is described, along with the results of its application of a 38-yr-old male hospitalized depressive with severe anger problems. The treatment approach follows a procedure called "stress inoculation," which consists of 3 basic stages: cognitive preparation, skill acquisition and rehearsal, and application practice. Pretreatment assessment of S's proneness to provocation by means of an anger inventory resulted in a score of 301; at discharge, after 3? wks of treatment, the score was 258. The relationship between anger and depression is discussed. (47 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Quantum states of he atoms adsorbed on surfaces of rare gas solids

Wave functions and energies for band states of helium atoms in the two-dimensional periodic potential at the surface of a semiinfinite rare gas solid have been studied. In the case of Kr and Ar substrates, the atoms are highly localized and, correspondingly, the band widths are small. In a third case, namely that of an argon crystal highly compressed to simulate the adsorption site density of the close-packed face of argon, much larger band widths were found. If this is a reasonable simulation, then band effects may be observable.     

Two-dimensional evaporation and substrate heterogeneity effects in submonolayer helium films

A model calculation is used to argue that the low-temperature, low-coverage specific heat of submonolayer⁴ He films is evidence for the evaporation of a two-dimensional, liquid ground state. The smearing effect of small substrate inhomogeneities is demonstrated, and the effects of the thermal excitation of the liquid state are estimated. Arguments as to why these effects are not present in³ He films are given.Work performed under the auspices of the U.S. Atomic Energy Commission.
