How individuals with first-episode psychosis positively contribute to their families: a grounded theory analysis

Section A consists of a review of the literature relating to positive contribution to families in first-episode psychosis. It highlights potential gaps in the research and possible avenues for future research. Section B presents the findings of the study. The aim of this grounded theory study was to explore whether individuals who have experienced first-episode psychosis positively contribute to their families. Additionally, the study aimed to construct an explanatory model of how positive contribution to families is viewed and supported following first-episode psychosis. Method: Fifteen participants took part in the study. Seven had direct experience of psychosis, seven were relatives and one was a partner of an individual with direct experience. Participants were interviewed separately, with the accounts analysed using Charmaz’s version of grounded theory (Charmaz, 2006). Results. The constructed theory suggested that individuals who have experienced first episode psychosis can and do contribute to their families, and that such contribution when noticed and valued can lead to an increase in well-being. The model suggests that contribution is shaped by the self-concept, the impact of psychosis, the opportunity for contribution and whether it is noticed. Conclusion. The constructed theory extends current research, and suggests that contribution can positively impact both the individual and family. Limitations and clinical implications of the research are explored and suggestions for further research given. Section C offers a focused evaluation of the research study. Topics of evaluation included reflections on the research process, learning experiences, further clinical implications and possible future research

An Analysis of the Stereotypes of Preacher’s Kids and its Application on their Spouses

The purpose of this study is to discover the results of the effects of stereotypes and under what conditions certain stereotypes occur. The focus of this study is to examine stereotypes connected to the children of a Protestant minister and the spouses of those children. Ethnographic interviews and surveys show that the stereotype does exist in two distinct ways. Children of ministers are expected to either be rebellious hellions or they are expected to be perfect role models. The stereotypes affect the respondents more as children and teenagers than as adults unless as an adult the child still attends the same church as the minister parent. Adult children of ministers not in the same church do not experience the stereotype as they had as children. The in-laws of ministers do not experience the same stereotypes that their spouses have and in some cases, not at all

Topology, Locality, and Aharonov-Bohm Effect with Neutrons

Recent neutron interferometry experiments have been interpreted as demonstrating a new topological phenomenon similar in principle to the usual Aharonov-Bohm (AB) effect, but with the neutron's magnetic moment replacing the electron's charge. We show that the new phenomenon, called Scalar AB (SAB) effect, follows from an ordinary local interaction, contrary to the usual AB effect, and we argue that the SAB effect is not a topological effect by any useful definition. We find that SAB actually measures an apparently novel spin autocorrelation whose operator equations of motion contain the local torque in the magnetic field. We note that the same remarks apply to the Aharonov-Casher effect.Comment: 9 page

Cytochrome Oxidase and Functional Coding in Primate Striate Cortex: A Hypothesis

In 1978, Margaret Wong-Riley stained sections of squirrel monkey striate cortex for the activity of the mitochondrial enzyme, cytochrome oxidase, and noticed a periodic distribution of “puffs” of increased enzyme activity in layers 2 and 3 (letter to D. Hubel cited in Livingstone and Hubel [1984]). Her discovery anticipated a whole series of anatomical and physiological findings from many laboratories that correlated with the distribution of this enzyme in the striate cortex of primates, yet there has never been a satisfactory explanation as to why the distribution of this enzyme, crucial for aerobic energy metabolism, would be related to the functional organization of visual cortex (Martin 1988). The puffs have also been called blobs, spots, dots, and patches, with the term blob used most frequently

Chains of interacting Brownian particles under strain

We consider the behaviour of a one-dimensional chain of interacting Brownian particles being slowly pulled apart. More precisely, the leftmost particle is fixed, while the rightmost is pulled away at slow speed ε > 0. The interaction between particles is through a pairwise potential U of finite range. If we wait for a long enough time, the distance between a pair of neighbouring particles will exceed the range of U so that these two particles no longer interact. When this happens, we consider the chain broken at this point. Our aim is to investigate how the speed of pulling affects where the chain breaks, in the limit as σ 0 is the noise intensity. In Chapter 3, we begin by treating the case that U is cut-off strictly convex. In particular, it does not go smoothly to zero. We find, roughly, that if ε > σ then the chain breaks at the end where it is pulled, while if ε < σ it has an equal probability to break at either end. Then in Chapter 4, we consider the case that U goes smoothly to zero. After approximating the shape of the total energy function, we find, roughly, that the threshold between pulling regimes is given by ε = σ4/3. Our approach is based on a careful analysis of sample path behaviour. Although we mostly consider overdamped dynamics, we also show in Chapter 4 that if the particles have mass εβ with β > 2, then the behaviour of the chain is well-approximated by that in the overdamped case

Classical and Quantum Interaction of the Dipole

A unified and fully relativistic treatment of the interaction of the electric and magnetic dipole moments of a particle with the electromagnetic field is given. New forces on the particle due to the combined effect of electric and magnetic dipoles are obtained. Four new experiments are proposed, three of which would observe topological phase shifts.Comment: 10 pages, Latex/Revtex. Some minor errors have been correcte
