Perceptions of Community-Based Advocates in Jefferson County, Colorado Concerning Intimate Partner Violence Against Women
This qualitative study explored perceptions of community-based advocates in Jefferson County, Colorado and their experience assisting victims of intimate partner violence against women. Open-ended interview questionnaires were collected from community-based advocates and used to derive the perceptions community-based advocates hold with regard to access to community resources, ability to establish social support, improve quality of life, and ultimately reduce re-abuse. Results of these perceptions were combined with and compared to previous secondary research by Deborah Bybee and Cris Sullivan. This research of victims\u27 perceived effectiveness combined with data collected from advocates\u27 perceived effectiveness allowed for further insight into intimate partner violence and the perceived effectiveness of advocacy in reducing re-abuse. It was determined that advocates perceived their involvement with IPV victims is positive for victims when compared to those not receiving advocacy. Advocates perceived they were unable to reduce re-abuse, however, it was stated by advocates that they hoped by providing safety planning and other resources that they would empower female IPV victims to make positive future decisions regarding their abusive relationship. The advocates\u27 combined with Bybee and Sullivan\u27s research illustrated that women who experienced strain have various barriers that inhibit their ability to leave an abusive relationship. Robert Merton\u27s Strain Theory framed the foundation for explaining intimate partner violence (IPV) against women
A Study of the Relationship Between Substance Abuse Treatment and Motivation
The relationship between motivational level and participation in a thirty day substance abuse treatment center was examined for 22 recovering substance abusers. Participants included 22 female clients at Bridgeway Counseling Services, inc. The participants volunteered to complete the Readiness to Change Questionnaire- Alcohol, the Readiness to Change Questionnaire-Drug, and a personal data form which contained demographic questions. Where it was predicted that there would be no relationship between motivational level and participation in a thirty-day substance abuse treatment program, it was found that there was a positive relationship. That is, participation in the thirty-day substance abuse treatment program increased the motivational level of the participants
Effects of Locus of Control and Timing of Retirement on Retirement Satisfaction
Previous research to determine which factors predict one\u27s satisfaction with retirement documents varying results. 200 retired Eastern Illinois University professors were surveyed to determine the effects of two factors, locus of control and timing of retirement, considered important on retirement satisfaction. A comparison was made between internal and external locus of control subjects who were placed into three conditions: those who retire early (before age 61), those who retire within the normal or average range (ages 62-66), and those who retire late (later than age 67). The first hypothesis was that those who retire early will have the highest level of satisfaction. Those who retire late will have the lowest level of satisfaction; average age retirees will fall in the middle range. The second hypothesis tested was that retirees with an internal locus of control will be more satisfied with retirement than those with an external locus of control. In addition, covariates of self-efficacy and length of retirement were introduced to strengthen the analysis. No significant differences were found for retirement satisfaction and these factors. Limitations and implications for further research are discussed
Investigation of reliability attributes and accelerated stress factors on terrestrial solar cells
Major effort during this reporting period was devoted to two tasks: improvement of the electrical measurement instrumentation through the design and construction of a microcomputer controlled short interval tester, and better understanding of second quadrant behavior by developing a mathematical model relating cell temperature to electrical characteristics. In addition, some preliminary work is reported on an investigation into color changes observed after stressing
Accommodation of penetrative strain during deformation above a ductile décollement
The accommodation of shortening by penetrative strain is widely considered as an important process during contraction, but the distribution and magnitude of penetrative strain in a contractional system with a ductile décollement are not well understood. Penetrative strain constitutes the proportion of the total shortening across an orogen that is not accommodated by the development of macroscale structures, such as folds and thrusts. In order to create a framework for understanding penetrative strain in a brittle system above a ductile décollement, eight analog models, each with the same initial configuration, were shortened to different amounts in a deformation apparatus. Models consisted of a silicon polymer base layer overlain by three fine-grained sand layers. A grid was imprinted on the surface to track penetra- tive strain during shortening. As the model was shortened, a series of box fold structures developed, with a zone of penetrative strain in the foreland. Penetrative strain in the foreland decreases away from the fold belt. Restoration of the model layers to the horizontal indicates that penetrative strain accounts for 90.5%-30.8% of total shortening in a brittle system with a ductile décollement, compared to 45.2%–3.6% within a totally brittle system. Analog model geometries were consistent with the deformation styles observed in salt-floored systems, such as the Swiss Jura. Penetrative strain has not been accounted for in previous studies of salt-floored regions and estimates of this type could help resolve concerns of missing shortening highlighted by global positioning system data
Beyond homozygosity mapping: family-control analysis based on Hamming distance for prioritizing variants in exome sequencing
A major challenge in current exome sequencing in autosomal recessive (AR) families is the lack of an effective method to prioritize single-nucleotide variants (SNVs). AR families are generally too small for linkage analysis, and length of homozygous regions is unreliable for identification of causative variants. Various common filtering steps usually result in a list of candidate variants that cannot be narrowed down further or ranked. To prioritize shortlisted SNVs we consider each homozygous candidate variant together with a set of SNVs flanking it. We compare the resulting array of genotypes between an affected family member and a number of control individuals and argue that, in a family, differences between family member and controls should be larger for a pathogenic variant and SNVs flanking it than for a random variant. We assess differences between arrays in two individuals by the Hamming distance and develop a suitable test statistic, which is expected to be large for a causative variant and flanking SNVs. We prioritize candidate variants based on this statistic and applied our approach to six patients with known pathogenic variants and found these to be in the top 2 to 10 percentiles of ranks
Azimuthal velocity profiles in Rayleigh-stable Taylor-Couette flow and implied axial angular momentum transport
We present azimuthal velocity profiles measured in a Taylor-Couette
apparatus, which has been used as a model of stellar and planetary accretion
disks. The apparatus has a cylinder radius ratio of , an
aspect-ratio of , and the plates closing the cylinders in the
axial direction are attached to the outer cylinder. We investigate angular
momentum transport and Ekman pumping in the Rayleigh-stable regime. The regime
is linearly stable and is characterized by radially increasing specific angular
momentum. We present several Rayleigh-stable profiles for shear Reynolds
numbers , both for
(quasi-Keplerian regime) and (sub-rotating regime)
where is the inner/outer cylinder rotation rate. None of the
velocity profiles matches the non-vortical laminar Taylor-Couette profile. The
deviation from that profile increased as solid-body rotation is approached at
fixed . Flow super-rotation, an angular velocity greater than that of
both cylinders, is observed in the sub-rotating regime. The velocity profiles
give lower bounds for the torques required to rotate the inner cylinder that
were larger than the torques for the case of laminar Taylor-Couette flow. The
quasi-Keplerian profiles are composed of a well mixed inner region, having
approximately constant angular momentum, connected to an outer region in
solid-body rotation with the outer cylinder and attached axial boundaries.
These regions suggest that the angular momentum is transported axially to the
axial boundaries. Therefore, Taylor-Couette flow with closing plates attached
to the outer cylinder is an imperfect model for accretion disk flows,
especially with regard to their stability.Comment: 22 pages, 10 figures, 2 tables, under consideration for publication
