Employee Age as a Moderator of the Relationship Between Ambition and Work Role Affect

Past research has demonstrated a negative relationship between ambition, or the desire to get ahead, and job satisfaction. In the present paper, age was hypothesized to moderate the relationship between ambition and job satisfaction such that the relationship between ambition and satisfaction is more negative for older employees than for younger employees. Three studies, with three criterion variables (promotion satisfaction, extrinsic job satisfaction, overall job satisfaction), were used to test the hypothesis. Results indicated support for the hypothesized interaction. The discussion focuses on the implications of the results for organizational and individual career management strategies

The implementation of chlamydia screening: a cross-sectional study in the south east of England

Background England's National Chlamydia Screening Programme (NCSP) provides opportunistic testing for under 25 year-olds in healthcare and non-healthcare settings. The authors aimed to explore relationships between coverage and positivity in relation to demographic characteristics or setting, in order to inform efficient and sustainable implementation of the NCSP. Methods The authors analysed mapped NCSP testing data from the South East region of England between April 2006 and March 2007 inclusive to population characteristics. Coverage was estimated by sex, demographic characteristics and service characteristics, and variation in positivity by setting and population group. Results Coverage in females was lower in the least deprived areas compared with the most deprived areas (OR 0.48; 95% CI 0.45 to 0.50). Testing rates were lower in 20 1324-year-olds compared with 15 1319-year-olds (OR 0.69; 95% CI 0.67 to 0.72 for females and OR 0.67; 95% CI 0.64 to 0.71 for males), but positivity was higher in older males. Females were tested most often in healthcare services, which also identified the most positives. The greatest proportions of male tests were in university (27%) and military (19%) settings which only identified a total of 11% and 13% of total male positives respectively. More chlamydia-positive males were identified through healthcare services despite fewer numbers of tests. Conclusions Testing of males focused on institutional settings where there is a low yield of positives, and limited capacity for expansion. By contrast, the testing of females, especially in urban environments, was mainly through established healthcare services. Future strategies should prioritise increasing male testing in healthcare settings

Walk A Hound, Lose A Pound, & Stay Fit for Seniors

Comparative Medicine - OneHealth and Comparative Medicine Poster SessionBackground: Obesity rates in older adults are linked with the national problem of limited physical activity (PA), resulting in chronic illness. Obesity-related illness and functional loss require innovative interventions. Older adult dog walkers maintained physical functioning over a 3 year period (Thorpe 2006). Dog walking may improve long-term PA by improving readiness and physical function. Purpose: The study aimed to test the association between dog walking and physical functioning. Methods: A three-group, repeated measures design tested efficacy of a 12-week (5 days/week) shelter dog walking program for community-dwelling adults over age 65. Three retirement facilities were assigned to the shelter dog walking (DW), human walking companion (HWC), or no-treatment control (C) group. DW group members selected a dog matching their walking capability & walked on a paved road at the animal shelter. HWC group members walked with a friend or spouse on a paved road at their residence. Both groups were accompanied by study staff. Pretest, mid-trial & posttest findings included 6-minute walk, weight, physical activity during the previous week, physical activity stage of change, mood & social support. Findings: Fifty-four adults participated {DW n=12, HWC n=23 & C n=19}. Fourteen males & 40 females, ranged in age from 67-97 years (Mean=85). The 6-minute walk compared pre and post for the DW group increased 28% (p=0.012), the HWC had a 4% increase (p=0.32) and the C group a 6% increase (p=0.18). Conclusions: DW group participants expressed affinity for the shelter dogs. The DW group's walking ability improved significantly. They stated that their balance & walking confidence improved. They stated that they liked the program because it “gets me out,” “is helping me to feel more confident,” & “is fun.” Dog walking may be beneficial to improve or maintain functioning in older adults. Walking speed is an important indicator of balance

Relationship of Patient Self-Administered COPD Assessment Test (CAT) to Physician Standard Assessment of COPD in a Family Medicine Residency Training Program

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in the United States. COPD is of particular concern in certain sectors of the country, including Central Appalachia where our clinic is located. Assessing patients with COPD presents many challenges as symptoms range from those considered typical such as shortness of breath and sputum production to those less often identified like anxiety and social isolation. We conducted a pilot study comparing physician standard assessment of COPD to patient self-assessment using the COPD Assessment Test (CAT). The CAT is an eight-item questionnaire that measures the impact COPD has on an individual patient’s well-being and daily life. Based on our small sample size, physicians tend to underestimate the impact of COPD on a patient’s daily life. This discrepancy did not differ significantly by year of residency. Potential clinical impact of these findings include the need for more formalized and frequent patient self-assessment of disease burden as well as increased COPD assessment training within the residency curriculum

Unique Challenges Testing SDRs for Space

This paper describes the approach used by the Space Communication and Navigation (SCaN) Testbed team to qualify three Software Defined Radios (SDR) for operation in space and the characterization of the platform to enable upgrades on-orbit. The three SDRs represent a significant portion of the new technologies being studied on board the SCAN Testbed, which is operating on an external truss on the International Space Station (ISS). The SCaN Testbed provides experimenters an opportunity to develop and demonstrate experimental waveforms and applications for communication, networking, and navigation concepts and advance the understanding of developing and operating SDRs in space. Qualifying a Software Defined Radio for the space environment requires additional consideration versus a hardware radio. Tests that incorporate characterization of the platform to provide information necessary for future waveforms, which might exercise extended capabilities of the hardware, are needed. The development life cycle for the radio follows the software development life cycle, where changes can be incorporated at various stages of development and test. It also enables flexibility to be added with minor additional effort. Although this provides tremendous advantages, managing the complexity inherent in a software implementation requires a testing beyond the traditional hardware radio test plan. Due to schedule and resource limitations and parallel development activities, the subsystem testing of the SDRs at the vendor sites was primarily limited to typical fixed transceiver type of testing. NASA s Glenn Research Center (GRC) was responsible for the integration and testing of the SDRs into the SCaN Testbed system and conducting the investigation of the SDR to advance the technology to be accepted by missions. This paper will describe the unique tests that were conducted at both the subsystem and system level, including environmental testing, and present results. For example, test waveforms were developed to measure the gain of the transmit system across the tunable frequency band. These were used during thermal vacuum testing to enable characterization of the integrated system in the wide operational temperature range of space. Receive power indicators were used for Electromagnetic Interference tests (EMI) to understand the platform s susceptibility to external interferers independent of the waveform. Additional approaches and lessons learned during the SCaN Testbed subsystem and system level testing will be discussed that may help future SDR integrator

Relationship of Patient Self-Administered COPD Assessment Test to Physician Standard Assessment of Chronic Obstructive Pulmonary Disease in a Family Medicine Residency Training Program

Assessing the global impact of chronic obstructive pulmonary disease (COPD) on a patient’s life can be difficult to perform in the clinical setting due to time constraints and workflow challenges. The primary objective of this study was to compare disease impact ratings between patient selfadministered COPD Assessment Test (CAT) and physician standard office assessment. This prospective study was conducted at a family medicine residency clinic in northeast Tennessee. The study included two study groups: 1) adult patients seen at the clinic during the 3-month study period with an active diagnosis of COPD, and 2) their physicians. Physicians’ assessment of the impact of COPD on their patients’ daily lives was compared to patients’ self-administered CAT assessments. Physician assessment of COPD impact and patient ssessment of CAT categories significantly differed (χ2 =11.0, P=0.012). There was very poor agreement between patient and physician ratings (κ=0.003), with 42.9% of physician ratings underestimating the impact, 28.6% overestimating the impact, and 28.6% orrectly estimating the impact COPD had on their patients’ lives. These findings support the use of validated assessment tools to help providers understand the symptom burden for patients with COPD
