Suicide Education to Support Caregivers in their Abilities to Care for Suicidal Individuals

Purpose: Suicide is a preventable act of lethality yet still remains a public health concern. Suicide can affect individuals from a variety of backgrounds and does not discriminate against age, gender, ethnicity, income, or occupation. Efforts to prevent suicide often focus on supporting the suicidal individual however there is a lack of available resources that focus on supporting those closest such as caregivers. Caregivers can play a pivotal role in their loved one’s trajectory towards recovery. The purpose of this project was to provide caregivers with a suicide toolkit that encompasses basic education, approaches to supporting a loved one who is suicidal, and community resources on prevention. Methods: This quality improvement project included information on evidenced based approaches, and local resources on suicide prevention. A total of twenty caregivers were included in this project that were divided into two separate groups: group A and group B. Ten caregivers were assigned to group A and asked to provide input as to what they felt a toolkit should encompass based on identified needs, this feedback was then used in part to develop a suicide toolkit. Group B consisted of a second set of ten caregivers who were asked to complete a pre and post questionnaire following the review of the suicide toolkit that was developed by the DNP student to see whether or not scores improved. Results: Eight out of ten caregivers from group A provided input for toolkit development. Four common themes emerged from this feedback that were included in the development of the toolkit. Ten caregivers in group B completed the pre and post questionnaire following the review of the toolkit and the means between these groups were compared and showed a slight improvement but not to the proposed 25% goal set forth. Conclusion: Post questionnaire scores showed improvement in comparison to pre questionnaire scores however several questions reflected no improvement in scores. This data may suggest that providing a toolkit alone does not elicit specific improvements in knowledge, confidence, competence, and perceived caring abilities, rather it can be a component of treatment. Several limitations are discussed including a small sample size used and little to no additional participant identifiers. Future recommendations include increasing the sample size and changing the phrasing of the questionnaire to better reflect caregiver experiences

Perturbative Calculation of Multi-Loop Feynman Diagrams. New Type of Expansions for Critical Exponents

We show that the calculation of L-loop Feynman integrals in D dimensions can be reduced to a series of matrix multiplications in D times L dimensions. This gives rise to a new type of expansions for the critical exponents in three dimensions in which all coefficients can be calculated exactly.Comment: Author Information under http://www.physik.fu-berlin.de/~kleinert/institution.html .

The lambda point experiment in microgravity

The motivation and potential for performing very high resolution measurements of the heat capacity singularity at the lambda point of helium in microgravity conditions was briefly discussed. It is clear that tests extending deep into the asymptotic region can be performed, where the theoretical predictions take on their simplest form. This advantageous situation should lead to a major improvement in the understanding of the range of applicability of current theoretical ideas in this field. The lambda transition holds out the prospect of giving the maximum advance of any system, and with the application of cryogenic techniques, the potential of this system can be realized. The technology for the initial experiments is already developed, and results could be obtained in 1990

HBT shape analysis with q-cumulants

Taking up and extending earlier suggestions, we show how two- and threedimensional shapes of second-order HBT correlations can be described in a multivariate Edgeworth expansion around gaussian ellipsoids, with expansion coefficients, identified as the cumulants of pair momentum difference q, acting as shape parameters. Off-diagonal terms dominate both the character and magnitude of shapes. Cumulants can be measured directly and so the shape analysis has no need for fitting.Comment: 8 pages, 6 figures for a total of 29 subfigs, revtex4.

Multiplier phenomenology in random multiplicative cascade processes

We demonstrate that the correlations observed in conditioned multiplier distributions of the energy dissipation in fully developed turbulence can be understood as an unavoidable artefact of the observation procedure. Taking the latter into account, all reported properties of both unconditioned and conditioned multiplier distributions can be reproduced by cascade models with uncorrelated random weights if their bivariate splitting function is non-energy conserving. For the alpha-model we show that the simulated multiplier distributions converge to a limiting form, which is very close to the experimentally observed one. If random translations of the observation window are accounted for, also the subtle effects found in conditioned multiplier distributions are precisely reproduced.Comment: 4 pages, 3 figure

Analytic multivariate generating function for random multiplicative cascade processes

We have found an analytic expression for the multivariate generating function governing all n-point statistics of random multiplicative cascade processes. The variable appropriate for this generating function is the logarithm of the energy density, ln epsilon, rather than epsilon itself. All cumulant statistics become sums over derivatives of ``branching generating functions'' which are Laplace transforms of the splitting functions and completely determine the cascade process. We show that the branching generating function is a generalization of the multifractal mass exponents. Two simple models from fully developed turbulence illustrate the new formalism.Comment: REVTeX, 4 pages, 2 PostScript figs, submitted to PR
