The effect administrators have on employee morale within the University of Arkansas Cooperative Extension Service

The purpose of this study was to describe the relationship between Arkansas County Extension County staff morale and their perceived relationship county staff had with their County Staff Chair. The University of Arkansas Cooperative Extension Service (UAEX) can utilize the results from this research to identify individuals who have the capacity to build high-quality relationships with staff members, thereby promoting higher levels of morale within the organization. Administrators can use this study to identify current or future leaders within the organization by identifying those who can promote high-quality relationships with county-level staff. Results from this study may also be used to identify individuals needing training in developing high-quality relationships. It utilized surveys to collect data. Therefore, Qualtrics was used to distribute the Leader-Member Exchange-7 (LMX-7) and the Staff Morale Questionnaire (SMQ) electronically through the UAEX email distribution list of county employees. Participants were asked to provide a numeric response (1-5) for the seven statements relating to the Leader-member exchange (LMX) on the LMX-7. Each statement had a different 5-point scale, but 1 represented the lowest rated response, 3 represented the average or neutral response, and 5 represented the highest rated response. In addition, participants were asked to provide a numeric response (1-4) where 1 = strongly disagree, 2 = disagree, 3 = agree, and 4 = strongly agree for the 27 statements relating to the three constructs (Leadership Synergy, Cohesive Pride, and Personal Challenge) of the SMQ. Overall, UAEX county employees reported moderate to high morale, which was directly related to their perceived quality of relationship with their County Staff Chair. The implications of this study suggest that leader-member relationships can affect employee morale in all three constructs measured. The higher the quality of relationship employees perceive with their staff chair, the higher their morale will be. County staff had moderate to high level of morale in each of the three constructs as measured by the SMQ. County-level staff also felt united in striving to achieve the goals and mission of their county office and Extension as a whole

Linear Analysis of a Two-Parachute System Undergoing Pendulum Motion

Motion resembling that of a pendulum undergoing large-amplitude oscillation was ob- served during a series of flight tests of an unoccupied Orion Capsule Parachute Assembly System (CPAS) drop-test vehicle. Large excursions away from vertical by the capsule could cause it to strike the ground or ocean at a large angle with respect to vertical, with an undesirable attitude with respect to heading, or with a large horizontal or vertical speed. These conditions are to be avoided because they would endanger the occupants of the capsule in an actual mission. Pendulum motion is intimately related to a parachutes aerodynamic normal force coefficient, which is a nonlinear function of angle of attack. An analytical investigation of the dynamics of pendulum motion is undertaken with the aid of a simplified model of the physical system and the assumption that the normal force coefficient is a linear function of angle of attack in the neighborhood of a value corresponding to stable equilibrium. The analysis leads to a simple relationship for the location of a pivot point, which provides insights that are consistent with previous studies

Buffalo National Insurance: Team Work Through Problem-Solving.

This paper examines a group of insurance professionals that developed into a self-directed Team at Buffalo National Insurance. The Team was not showing Team unity, thus, the Team did not meet performance goals. Led by an internal consult that collaborated with management, the Team and the Team Leader created an environment that allowed for Team unity and the effective use of a new problem-solving tool known as Continuous Improvement Model (CIM). The intervention strategy was successful in enhancing human performance because the intervention was implemented in (a) real time (b) during actual business conditions and (c) using actual business problems. This approach did not remove the developing Team from the workplace thus minimizing lost productivity and performance. The Human Resource Development (HRD) professional who wants to engender credibility and trust with business customers will want to understand the reasons why this intervention method was effective

Detection of spatiotemporal variation in ranavirus distribution using eDNA

Amphibian population declines have been associated with emerging diseases including ranaviruses, which can cause mass die‐offs across entire amphibian communities. Understanding and mitigating disease spread requires knowledge of spatial and temporal patterns of pathogen distribution, but also how environmental factors influence pathogen occurrence. We applied environmental DNA (eDNA) detection tools to survey spatial and temporal distributions of ranaviruses by sampling 103 waterbodies in southeastern Ontario, Canada and assessed the role of abiotic factors as predictors of pathogen occurrence. Ten waterbodies sampled during June–August (>30 km between sites) revealed that ranavirus was marginally more prevalent (p = .055) during the latter part of the summer. Ninety‐three sites sampled at a finer scale (<10 km between sites) exhibited seasonal variability in ranavirus detection (site prevalence: 56% May; 66% July). Occupancy modeling revealed that wetland size and elevation influenced ranavirus occurrence while sampling date and water temperature influenced probability of detection. These findings indicate that biotic factors, such as host density and alternative hosts, should be investigated further as likely determinants of ranavirus prevalence across the landscape. Further, these results highlight the sensitivity of eDNA for detecting widespread presence of ranavirus and that abiotic factors may have a limited role in determining its prevalence and infectivity

Epidemiology, genetics, and subtyping of preserved ratio impaired spirometry (PRISm) in COPDGene.

BackgroundPreserved Ratio Impaired Spirometry (PRISm), defined as a reduced FEV1 in the setting of a preserved FEV1/FVC ratio, is highly prevalent and is associated with increased respiratory symptoms, systemic inflammation, and mortality. Studies investigating quantitative chest tomographic features, genetic associations, and subtypes in PRISm subjects have not been reported.MethodsData from current and former smokers enrolled in COPDGene (n = 10,192), an observational, cross-sectional study which recruited subjects aged 45-80 with ≥10 pack years of smoking, were analyzed. To identify epidemiological and radiographic predictors of PRISm, we performed univariate and multivariate analyses comparing PRISm subjects both to control subjects with normal spirometry and to subjects with COPD. To investigate common genetic predictors of PRISm, we performed a genome-wide association study (GWAS). To explore potential subgroups within PRISm, we performed unsupervised k-means clustering.ResultsThe prevalence of PRISm in COPDGene is 12.3%. Increased dyspnea, reduced 6-minute walk distance, increased percent emphysema and decreased total lung capacity, as well as increased segmental bronchial wall area percentage were significant predictors (p-value <0.05) of PRISm status when compared to control subjects in multivariate models. Although no common genetic variants were identified on GWAS testing, a significant association with Klinefelter's syndrome (47XXY) was observed (p-value < 0.001). Subgroups identified through k-means clustering include a putative "COPD-subtype", "Restrictive-subtype", and a highly symptomatic "Metabolic-subtype".ConclusionsPRISm subjects are clinically and genetically heterogeneous. Future investigations into the pathophysiological mechanisms behind and potential treatment options for subgroups within PRISm are warranted.Trial registrationClinicaltrials.gov Identifier: NCT000608764

Planning Considerations for a Mars Sample Receiving Facility: Summary and Interpretation of Three Design Studies

It has been widely understood for many years that an essential component of a Mars Sample Return mission is a Sample Receiving Facility (SRF). The purpose of such a facility would be to take delivery of the flight hardware that lands on Earth, open the spacecraft and extract the sample container and samples, and conduct an agreed-upon test protocol, while ensuring strict containment and contamination control of the samples while in the SRF. Any samples that are found to be non-hazardous (or are rendered non-hazardous by sterilization) would then be transferred to long-term curation. Although the general concept of an SRF is relatively straightforward, there has been considerable discussion about implementation planning. The Mars Exploration Program carried out an analysis of the attributes of an SRF to establish its scope, including minimum size and functionality, budgetary requirements (capital cost, operating costs, cost profile), and development schedule. The approach was to arrange for three independent design studies, each led by an architectural design firm, and compare the results. While there were many design elements in common identified by each study team, there were significant differences in the way human operators were to interact with the systems. In aggregate, the design studies provided insight into the attributes of a future SRF and the complex factors to consider for future programmatic planning
