A qualitative analysis of clinical records from a trauma response program for families exposed to violence

This dissertation is a qualitative secondary content analysis of clinical records collected for the Spokane Safe Start Project in Spokane, Washington, a program designed to offset trauma in children exposed to domestic and intimate partner violence (IPV). The Centers for Disease Control and the World Health Organization have identified intimate partner violence (IPV) as a health policy issue. Most studies of intimate partner violence and children exposed to violence have used samples from domestic violence shelters, large phone-based community surveys, or convenience samples such as college students. Currently, studies of families that have experienced intimate partner violence and received services in their homes do not exist. As such, the process and effects of intimate violence in families residing in their homes have not been identified. The purpose of this study was to identify the structural issues, factors affecting service engagement, family characteristics, and factors promoting resiliency in families that experienced intimate partner violence and were served by the Spokane Safe Start Project in Spokane, Washington, a program designed to offset trauma in children exposed to caregiver intimate partner violence. To this end, the four research questions were: 1) What are the underlying structural problems that affected these families? 2) Is family functioning at intake associated with the length of time with the program? 3) Of the families that engaged with Safe Start for at least five face-to-face contacts, what are the caregiver and/or family characteristics that seem to indicate the presence or absence of resilience in the caregivers? This study involved the analysis of the clinical case records of 30 families that received Spokane Safe Services. The primary source of data for this study came from the narrative portions of the electronic ACCESS and written client clinical records. The Spokane Safe Start clinical narratives served as a record of clinician observations, interactions, and service delivery to families greatly affected by intimate partner violence. Using the bio-ecological perspective and family systems theory as the theoretical frameworks to understand intimate partner violence and its effects on children, data analysis and synthesis, I used qualitative content analysis thematic analysis, and data matrices. In essence, this is a multiple case study producing "context-dependent knowledge" that is vital to develop ecologically sound interventions to address intimate partner violence and its effects on families (Flyvbjerg, 2006, p. 221). This study revealed three main findings. Families encountered roadblocks in the form of environmental and individual obstacles. These obstacles included family-of-origin dynamics, severe financial problems, and individual issues such as relationship ambivalence and substance abuse that posed serious limitations to developing resilience. Parent-child interactions were strained and difficult in most families. The majority of children experienced chronic IPV and many had a history of maltreatment as well. Although many parents were concerned about the future wellbeing of their children, they also had difficulty reflecting on their children’s emotional needs and experiences. Evidence of resilience in the case narratives was quite limited. There was evidence, one particular clinician's model of service provision was more successful at engendering resilience than that of the other clinicians. Results were triangulated with the extant literature and previous quantitative studies conducted by Washington State University on the Spokane Safe Start data indicating the results of this study are trustworthy and credible. This study makes an important contribution to the family violence literature and may serve as a resource for policy and program development.

Carrier-induced ferromagnetism in n-type ZnMnAlO and ZnCoAlO thin films at room temperature

The realization of semiconductors that are ferromagnetic above room temperature will potentially lead to a new generation of spintronic devices with revolutionary electrical and optical properties. Transition temperatures in doped ZnO are high but, particularly for Mn doping, the reported moments have been small. We show that by careful control of both oxygen deficiency and aluminium doping the ferromagnetic moments measured at room temperature in n-type ZnMnO and ZnCoO are close to the ideal values of 5mB and 3mB respectively. Furthermore a clear correlation between the magnetisation per transition metal ion and the ratio of the number of carriers to the number of transition metal donors was established as is expected for carrier induced ferromagnetism for both the Mn and Co doped films. The dependence of the magnetisation on carrier density is similar to that predicted for the transition temperature for a dilute magnetic semiconductor in which the exchange between the transition metal ions is through the free carriers.Comment: 14 pages pd

The dose-response of the nordic hamstring exercise on biceps femoris architecture and eccentric knee flexor strength : A randomized interventional trial

Purpose: To examine the dose–response of the Nordic hamstring exercise (NHE) on biceps femoris long head (BFlh) architecture and eccentric knee flexor strength. Design: Randomized interventional trial. Methods: Forty recreationally active males completed a 6-week NHE training program consisting of either intermittent low volumes (group 1; n = 10), low volumes (group 2; n = 10), initial high volumes followed by low volumes (group 3; n = 10), or progressively increasing volumes (group 4; n = 10). A 4-week detraining period followed each program. Muscle architecture was assessed weekly during training and after 2 and 4 weeks of detraining. Eccentric knee flexor strength was assessed preintervention and postintervention and after 2 and 4 weeks of detraining. Results: Following 6 weeks of training, BFlh fascicle length (FL) increased in group 3 (mean difference = 0.83 cm, d = 0.45, P = .027, +7%) and group 4 (mean difference = 1.48 cm, d = 0.94, P = .004, +14%). FL returned to baseline following detraining in groups 3 and 4. Strength increased in group 2 (mean difference = 53.6 N, d = 0.55, P = .002, +14%), group 3 (mean difference = 63.4 N, d = 0.72, P = .027, +17%), and group 4 (mean difference = 74.7, d = 0.83, P = .006, +19%) following training. Strength returned to baseline following detraining in groups 2 and 3 but not in group 4. Conclusions: Initial high volumes of the NHE followed by lower volumes, as well as progressively increasing volumes, can elicit increases in BFlh FL and eccentric knee flexor strength. Low volumes of the NHE were insufficient to increase FL, although as few as 48 repetitions in 6 weeks did increase strength

Room temperature magneto-optics of ferromagnetic transition-metal doped ZnO thin films

Magneto-optic studies of ZnO doped with transition metals Co, Mn, V and Ti indicate a significant magnetic circular dichroism (MCD) at the ZnO band edge at room temperature, together with an associated dispersive Faraday rotation. Similar spectra occur for each dopant which implies that the ferromagnetism is an intrinsic property of the bulk ZnO lattice. At 10 K additional paramagnetic contributions to the MCD are observed, but above about 150K, the magnitude of the MCD signal is dominated by the ferromagnetism and is almost temperature independent. The MCD at the ZnO band edge shows room temperature hysteretic behaviour.Comment: 4 page

Evolution of the Corticotropin-releasing Hormone Signaling System and Its Role in Stress-induced Phenotypic Plasticity

Developing animals respond in variation in their habitats by altering their rules of development and/or their morphologies (i.e., they exhibit phenotypic plasticity). In vertebrates, one mechanism by which plasticity is expressed is through activation of the neuroendocrine system, which transduces environmental information into a physiological response. Recent findings of ours with amphibians and of others with mammals show that the primary vertebrate stress neuropeptide, corticotropin-releasing hormone (CRH), is essential for adaptive developmental responses to environmental stress. For instance, CRH-dependent mechanisms cause accelerated metamorphosis in response to pond-drying in some amphibian species, and intrauterine fetal stress syndromes in humans precipitate preterm birth. CRH may be a phylogenetically ancient developmental signaling molecule that allows developing organisms to escape deleterious changes in their larval/fetal habitat. The response to CRH is mediated by at least two different receptor subtypes and may also be modulated by a secreted binding protein.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73287/1/j.1749-6632.1999.tb07877.x.pd

A pandemic strain of calicivirus threatens rabbit industries in the Americas

Rabbit Hemorrhagic Disease (RHD) is a severe acute viral disease specifically affecting the European rabbit Oryctolagus cuniculus. As the European rabbit is the predominant species of domestic rabbit throughout the world, RHD contributes towards significant losses to rabbit farming industries and endangers wild populations of rabbits in Europe and other predatory animals in Europe that depend upon rabbits as a food source. Rabbit Hemorrhagic Disease virus (RHDV) – a Lagovirus belonging to the family Caliciviridae is the etiological agent of RHD. Typically, RHD presents with sudden death in 70% to 95% of infected animals. There have been four separate incursions of RHDV in the USA, the most recent of which occurred in the state of Indiana in June of 2005. Animal inoculation studies confirmed the pathogenicity of the Indiana 2005 isolate, which caused acute death and pathological changes characterized by acute diffuse severe liver necrosis and pulmonary hemorrhages. Complete viral genome sequences of all USA outbreak isolates were determined and comparative genomics revealed that each outbreak was the result of a separate introduction of virus rather than from a single virus lineage. All of the USA isolates clustered with RHDV genomes from China, and phylogenetic analysis of the major capsid protein (VP60) revealed that they were related to a pandemic antigenic variant strain known as RHDVa. Rapid spread of the RHDVa pandemic suggests a selective advantage for this new subtype. Given its rapid spread, pathogenic nature, and potential to further evolve, possibly broadening its host range to include other genera native to the Americas, RHDVa should be regarded as a threat

The Relationships among Trait Anxiety, State Anxiety and the Goal Performance of Penalty Shoot-Out by University Soccer Players

The present study examined how the level of trait anxiety, which is a personality characteristic, influences state anxiety and penalty shoot-out performance under pressure by instruction. The high and low trait anxiety groups were selected by using Spielberger's Trait Anxiety Scale, with trait anxiety scores, and control and pressure conditions manipulated by instructions. The participants were two groups of eight university male soccer players. They individually performed 20 shots from the penalty shoot-out point, aiming at the top right and top left corner areas in the soccer goal. Each condition had 10 trials in a within-subject design. The dependent measures comprised the number of successful goals and the state anxiety scores under each instructional condition. The result showed a significant main effect of instruction. State anxiety scores increased more and the number of successful goals decreased more in high trait anxiety groups than in low trait anxiety groups under pressure instructional condition. These findings suggest that players with higher trait anxiety scores tend to experience increased state anxiety under a pressure-laden condition, and higher state anxiety interferes with goal performance
