Jockey Falls, Injuries, and Fatalities Associated With Thoroughbred and Quarter Horse Racing in California, 2007-2011.
BackgroundDespite the popularity of the horse racing industry in the United States and the wide recognition that horse racing is one of the most hazardous occupations, little focused research into the prevention of falls by and injuries to jockeys has been conducted.PurposeTo describe the incidence rates and characteristics of falls and injuries to Thoroughbred and Quarter Horse racing jockeys in the state of California.Study designDescriptive epidemiology study.MethodsData on race-day falls and injuries were extracted from jockey accident reports submitted to the California Horse Racing Board from January 2007 to December 2011. Denominator data, number of jockey race rides, were obtained from commercial and industry databases. Jockey fall, injury, and fatality incidence rates and ratios in Thoroughbred and Quarter Horse flat races were estimated using Poisson regression. Characteristics of falls and injuries are described and compared.ResultsIn Thoroughbred races, 184 jockey injuries occurred from 360 reported jockey falls, 180,646 race rides, 23,500 races, and 3350 race meetings. In Quarter Horse races, 85 jockey injuries occurred from 145 jockey falls, 46,106 race rides, 6320 races, and 1053 race meetings. Jockey falls occurred at a rate of 1.99 falls per 1000 rides in Thoroughbred races, with 51% of falls resulting in jockey injury, and 3.14 falls per 1000 rides in Quarter Horse races, with 59% of falls resulting in jockey injury. The majority of falls occurred during a race, with catastrophic injury or sudden death of the horse reported as the most common cause in both Thoroughbred (29%) and Quarter Horse (44%) races. During the period studied, 1 jockey fatality resulted from a fall. Jockey fall rates were lower but injury rates were comparable to those reported internationally.ConclusionOn average, a licensed jockey in California can expect to have a fall every 502 rides in Thoroughbred races and every 318 rides in Quarter Horse races. While jockey fall rates were lower, injury rates were similar to those in other racing jurisdictions. The high proportion of jockey falls caused by horse fatalities should be further investigated
Financial Stress and Marital Quality: The Moderating Influence of Couple Communication
This study explores the negative relationship between financial stress and marital quality and examines couple communication as a moderator in this relationship. Using a sample of 373 married U.S. couples from the Flourishing Families Project, an Actor-Partner Interdependence Model (APIM) was run to determine the influence of husbands’ and wives’ financial stress on both their own and their partner’s reports of marital quality. Results found negative associations between both actor and partner reports of financial stress and marital quality. Couple communication did not moderate the associations between husbands’ and wives’ financial stress and wives’ marital quality. However, it did moderate the negative associations between both husbands’ and wives’ financial stress and husbands’ marital quality. Specifically, the deleterious relationship of financial stress to marital quality for husbands was significantly less severe when coupled with positive couple communication. Implications for financial therapists and avenues for future research are discussed
Modeling the impact of vaccination control strategies on a foot and mouth disease outbreak in the Central United States
The central United States (U.S.) has a large livestock population including cattle, swine, sheep and goats. Simulation models were developed to assess the impact of livestock herd types and vaccination on foot and mouth disease (FMD) outbreaks using the North American Animal Disease Spread Model. In this study, potential FMD virus outbreaks in the central region of the U.S. were simulated to compare different vaccination strategies to a depopulation only scenario. Based on data from the U.S. Department of Agriculture National Agricultural Statistics Service, a simulated population of 151,620 livestock operations characterized by latitude and longitude, production type, and herd size was generated. For the simulations, a single 17,000 head feedlot was selected as the initial latently infected herd in an otherwise susceptible population. Direct and indirect contact rates between herds were based on survey data of livestock producers in Kansas and Colorado. Control methods included ring vaccination around infected herds. Feedlots ≥3000 head were either the only production type that was vaccinated or were assigned the highest vaccination priority. Simulated vaccination scenarios included low and high vaccine capacity, vaccination zones of 10 km or 50 km around detected infected premises, and vaccination trigger of 10 or 100 detected infected herds. Probability of transmission following indirect contact, movement controls and contact rate parameters were considered uncertain and so were the subjects of sensitivity analysis. All vaccination scenarios decreased number of herds depopulated but not all decreased outbreak duration. Increased size of the vaccination zone during an outbreak decreased the length of the outbreak and number of herds destroyed. Increased size of the vaccination zone primarily resulted in vaccinating feedlots ≥3000 head across a larger area. Increasing the vaccination capacity had a smaller impact on the outbreak and may not be feasible if vaccine production and delivery is limited. The ability to vaccinate all the production types surrounding an infected herd did not appear as beneficial as priority vaccination of feedlot production types that have high numbers of indirect contacts. Outbreak duration, number of herds depopulated and the effectiveness of vaccination were sensitive to indirect contact transmission probability and movement restrictions. The results of this study will provide information about the impacts of disease control protocols which may be useful in choosing the optimal control methods to meet the goals of rapid effective control and eradication
Perceived Family and Partner Support and the Work-Family Interface: A Meta-Analytic Review
This study employed meta-analytic techniques to elucidate the role of perceived partner and family support in four measures of the work-family interface. We extracted 183 effect sizes from 82 samples and a total of N = 36,226 individuals. We found perceived familial (partner and family) support was negatively associated with work-to-family conflict (r = -.099) and family-to-work conflict (r = -.178). It was positively associated with work-to-family enrichment (r = .173) and family-to-work enrichment (r = .378). Various sample-level moderators were investigated through meta regression and subgroup analyses, including whether the support measure was family or partner focused. Perceived family support showed larger magnitude associations with the two conflict outcome variables than partner support, while there were no significant differences between family and partner support and the two enrichment outcomes. The results suggest that familial support is an essential component of successfully minimizing work-family conflict and maximizing work-family enrichment, and that whether the measure of support is partner or family specific may impact the magnitude of results
How do Money, Sex, and Stress Influence Marital Instability?
This study explored how money and sex simultaneously predicted marital instability, and what financial therapists might focus on with clients to address problems in these areas. Specifically, this paper concurrently examined the relationship of marital instability to financial and family stressors (financial stressors, work-family conflict, and parenting stressors); financial and sexual resources (couple income and couple sexual frequency); and financial and sexual perceptions (financial dissatisfaction and sexual dissatisfaction). Couple financial communication and couple relational communication were explored as intervention points for financial therapists. Data came from Wave 2 of the Flourishing Families data set (N = 301). Data were organized using the ABC-X model of family stress (Hill, 1949) and integrated with Gottman\u27s research on the importance of relational communication (Navarra, Gottman, & Gottman, 2016). Path analysis revealed that family financial stressors were associated with greater financial dissatisfaction and sexual dissatisfaction. Work-family conflict was associated with greater couple income, and parenting stressors were positively associated with sexual dissatisfaction. Couple income was associated with lower financial dissatisfaction, and sexual frequency was associated with lower sexual dissatisfaction. Both financial dissatisfaction and sexual dissatisfaction predicted greater marital instability; however, healthy couple financial communication and healthy couple relationship communication fully mediated these two associations. This suggests that if financial therapists help clients to communicate more productively about money and sex, problems such as financial stress, work-family conflict, inadequate income, and conflicts about sexual frequency may be less likely to lead to divorce
Comparative study of the commonly used virulence tests for laboratory diagnosis of ovine footrot caused by Dichelobacter nodosus in Australia.
Footrot in sheep and goats is expressed as a spectrum of clinical entities ranging from benign, which is a self limiting interdigital dermatitis to highly virulent, in which severe under running of the horn of the hoof occurs. Interactions between the host, the virulence of the causative strain of Dichelobacter nodosus and environmental conditions determine the severity of the disease. Clinical diagnosis of virulent footrot, which a notifiable disease in some states of Australia, is not always straightforward. Therefore, the Gelatin Gel and Elastase tests for protease activity, and the intA PCR test for an inserted genetic element in D. nodosus are commonly used to support or to confirm a clinical diagnosis. A comparative study of these laboratory tests with a large number of samples collected from 12 flocks of sheep with clinically virulent footrot was conducted. Based on the elastase test, 64% of the isolates tested were classified as virulent compared to 91% on the gelatin gel test and 41% according to the intA test. The agreement between the elastase and the gelatin gel test was low (kappa =0.12) as were the agreements between other tests. Only about 21% of the isolates were virulent in all 3 tests. Therefore these tests on their own may not provide standard and reliable results and are likely to remain as supplementary tests for clinical diagnosis of the disease.

Feminism and Couple Finance: Power as a Mediator Between Financial Processes and Relationship Outcomes
Feminism is rarely used as a theoretical framework for couple finance research. The purposes of the present paper are (a) to discuss couple finance research in the context of feminism to encourage more frequent and explicit use of feminism in couple finance research, (b) to present a gender and couple finances model, and (c) to test this model with longitudinal dyadic data. Using actor-partner interdependence models (APIM) and data from 327U.S. mixed-gender couples, relational power was explored as a potential mediator between four couple financial processes (earners of money, access to money, management of money, and conflict about money) and two relationship outcomes (relationship quality and relationship stability). Results suggest that couple financial processes are associated with relationship outcomes and with joint management as well as low conflict being key longitudinally. Additionally, although power may not play a mediating role, it appears to be connected to couple financial processes and relationship outcomes concurrently. Gender differences as well as both actor and partner effects are explored. This research has implications for researchers, clinicians, and educators. For example, clinicians may want to encourage their clients to use joint bank accounts, manage their money jointly, and minimize financial conflict. Gender, and therefore power, are inseparably tied to couple finances. When both spouses are involved in financial processes, partners tend to be more empowered, and relationship quality and stability tend to be higher.12 month embargo; published online: 26 November 2018This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
