Effects of differential rules on production of verbal behaviour associated with dissociative identity disorder in a mock legal contextCampbell, Kristen Lynn 31 January 2008 (has links)
The role of rule-governance in producing verbal behaviour associated with dissociative identity disorder (DID) was investigated, using a single-factor, between-subjects design. Fifty-two undergraduates role-played the part of an accused murderer undergoing a psychiatric assessment to prepare a legal defense. Participants were assigned randomly to one of three groups, a DID rule group, a self-defense rule group, or a control group. Participants then underwent a mock psychiatric assessment. Specific verbal behaviour of participants during the assessment was analyzed between groups. The hypothesis that individuals in the DID group would demonstrate more verbal behaviour associated with DID than those in either of the other groups was supported by data from a structured interview and a self-report measure; however, a statistically significant difference among groups was observed on only one (initial denial) of six dimensions on an unstructured interview. This latter result suggests that the contextual cues and perceived situational demands associated with the mock psychiatric interview were powerful enough to overcome the effect of the differential instructions. / February 2008

Identification of Dissociative Experiences in Children and AdolescentsQueener, Heather L. (Heather Lynn) 08 1900 (has links)
This study attempts to quantify the dissociative experiences reported by children and adolescents, and to determine whether the variance in degree of dissociation in children has useful diagnostic and treatment implications.

Dynamics in the Dissociative Recombination of Small Polyatomic Molecular IonsZhaunerchyk, Vitali January 2008 (has links)
<p>Dissociative recombination (DR) is a process in which a positive molecular ion recombines with an electron and subsequently dissociates into neutral fragments. Among the different types of molecular ion-electron reactions DR deserves particular attention due to the important role it plays in low-temperature and low-density plasmas. Despite the apparent simplicity of the DR reaction, its investigation has proven to be a difficult task from both experimental and theoretical perspectives. In order to shed more light upon this process the storage ring technique has been introduced and utilised extensively for the last few decades. This thesis is devoted to experimental studies into the DR reaction at the storage ring CRYRING. The DR reaction has been investigated for the following molecular ions; Na<sup>+</sup>(D<sub>2</sub>O), PD<sub>2</sub><sup>+</sup>, O<sub>3</sub><sup>+</sup>, N<sub>3</sub><sup>+</sup>, H<sub>2</sub><sup>+</sup>, D<sub>2</sub>H<sup>+</sup>, OPCl<sup>+</sup>, OPCl<sub>2</sub><sup>+</sup> and H<sub>3</sub>O<sup>+</sup>, with the aim to ascertain rotational state effects, to find patterns in the branching products of similar molecular ions, to investigate isotope effects and to study in detail the dynamics involved in the three-body break-up channel.</p>

Dissociative recombination of organic molecular ions of relevance for interstellar clouds and Titan's upper atmosphereVigren, Erik January 2010 (has links)
This thesis presents experimental studies on the dissociative recombination (DR) of the organic molecular ions CD3CND+, CH2CHCNH+, CH3CH2CNH+, CD3CDO+, CH3CHO+ and DCOOD2+. The experiments were all performed at the heavy ion storage ring CRYRING at the Manne Siegbahn Laboratory in Stockholm, Sweden. DR is the process in which a singly charged molecular cation captures a free electron, forming a highly excited intermediate molecule which then dissociates into exclusively neutral fragments. The process plays an important role as a plasma neutralizing mechanism in many cold, low density plasmas such as those encountered in planetary ionospheres and interstellar clouds. DR can also act as the final step in the gas-phase synthesis of different neutral molecules in such environments. Our experimental findings indicate that nitriles that are lost by protonation in Titan’s upper atmosphere or in interstellar clouds to a large extent may be recycled by DR. Also, it appears that the DR of nitrile ions does not break the C-N bond, which supports the hypothesis that nitriles which are formed in Titan’s upper atmosphere do not degrade to recover N2. For the studied acetaldehyde cations, CD3CDO+ and CH3CHO+, we observed a considerable isotopic effect in the cross section, with the lighter isotopologue being more reactive. In the DR of DCOOD2+ an upper limit of only 13% for the branching fraction of the DCOOD + D channel was found. This finding has pronounced effects on the predicted abundance of formic acid in dark clouds.

Theoretical And Computational Studies Of Dissociative Recombination Of H3+ With Low Kinetic Energy Electrons: Time-independent ASantos, Samantha 01 January 2009 (has links)
Dissociative recombination of molecular ions by collisions with electrons is a reactive collision, in which the electronic kinetic energy is transferred to the excitation of the molecule that, then, dissociates. The goals of this dissertation was (1) to improve existing approaches in theory of DR of triatomic ions in the time-independent framework developed in recent years by Kokoouline and Greene, and (2) to develop a time-dependent theoretical framework for DR treatment based on quantum defect theory. The theoretical method developed by Kokoouline and Greene is based on multichannel quantum defect theory and accounts for the major non-Born-Oppenheimer Jahn-Teller interaction between electronic and vibrational motions of the molecule. The study of this dissertation is partially based on this method but improved, extended, and systematically applied in the framework of my thesis. This dissertation presents the calculated DR rate coefficient for H3+ within the time-independent framework and the description of the method used to obtain the (qualitative) flux with time-dependent method. The time-independent results show good agreement with experimental data from storage ring experiments. The DR rate coefficients for ortho- and para-H3+ were calculated separately and show a significant difference at very low electronic energies; a result that agrees with recent storage ring experiments. Also, it is discussed results for other isotopologues of H3+ (H2D+, D2H+, and D3+) and the results for vibrationally-excited initial states of H3+. It was found that the DR rate coefficients for vibrationally-excited initial states are larger than the rates for the ion initially in the ground vibrational state. At the end, this dissertation discuss the time-dependent calculations done with a diatomic model system.
