Refan program. Phase 1: Summary report

The Refan Program is aimed at a large reduction in aircraft approach and takeoff noise in the vicinity of airports caused by the JT3D-powered 707's and DC-8's and the JT8D-powered 727's, 737's and DC-9's. These aircraft represent a major part of the existing commercial fleet. The noise reductions can be achieved by engine and nacelle modifications in the form of aircraft retrofit kits. Engine turbomachinery noise is reduced by replacing the current two-stage fan with a larger single-stage fan and by nacelle acoustic treatment. Jet noise is reduced by the reduction on jet velocity caused by additional turbine work extraction to drive the larger bypass fan. The predicted net effect of these modifications on installed performance is large noise reductions on both approach and takeoff, increased takeoff thrust, decreased takeoff field length, and maintained or improved aircraft range depending on the amount of acoustic treatment included. The Refan Program is being conducted in two phases under contracts with one engine and two airframe companies. Results of the Phase I work are summarized in this report which describes the refan nacelle configurations studied, the airplane modifications required to install the nacelles, and the resulting airplane performance and noise reductions predicted for all five aircraft

A Program Evaluation Using Stufflebeam’s CIPP Model to Evaluate Educational Service Unit 2 (Esu 2) Consortium for Special Education of Administration Services (Cases)

The purpose of the study is to conduct a program evaluation utilizing Stufflebeam’s 2007 CIPP Model to determine if the Educational Service Unit 2 (ESU 2) Consortium for Administration of Special Education Services (CASES) effectively serves CASES member districts. The results of the program evaluation is intended to provide Educational Service Unit 2 (ESU 2) with results and feedback on how 1) to determine the extent to which CASES has successfully met program goals (Product Evaluation), efficiently utilized resources (Input Evaluation), and appropriately selected and implemented program activities (Process Evaluation), and 2) to examine how the program was developed (Context Evaluation), and to determine what program components are beneficial, what needs to be improved, and what can influence longevity of CASES and for other ESUs to utilize. A survey was sent out to staff members of the 13 ESU 2 CASES school districts that participate in CASES to gather perception data regarding CASES services in the areas of service, delivery, and accountability. The data collected during this program evaluation indicates that ESU 2 CASES services are something that the ESU 2 CASES member districts value, continue to need, and find to be a positive experience

Primate Aesthetics

A cultural, historical, and scientific survey of the phenomena of primate pictorial behavior, presented in a series of interconnected vignettes. What do primates find visually appealing? What is their motivation when creating images? What are the implications for art and for science? By drawing explicit and implicit connections between science, art, case studies, research, and personal narrative, I attempt to weave together what we know, and what we may never be able to know about this complex field

Forgiveness, Mental Health, and Adult Children of Alcoholics.

Research has shown that spirituality can play a role in addiction and recovery. However, little work in this area has focused on adults who have grown up with parents who have had alcohol and/or drug problems. Cross-sectional data was collected from college students from a regional university in southern Appalachia. Multiple dimensions and aspects of forgiveness and mental health were examined among undergraduates, including differences based upon participants’ likelihood of being an adult child of an alcoholic (ACOA). Individuals likely to be an ACOA had poorer levels of the forgiveness and mental health related variables. Among ACOAs forgiveness of others was associated with psychological distress and somatic symptoms in a deleterious fashion. Forgiveness of situations was associated with mental health status, psychological distress, and dysfunctional behaviors associated with being an ACOA in a salutary fashion. The process of forgiveness intervention may be an added benefit during the recovery process associated with growing up as a child in an alcoholic family

Comparison of Static and Countermovement Jump Variables in Relation to Estimated Training Load and Subjective Measures of Fatigue

The purpose of this study was to compare changes in static and countermovement jump variables across a competitive season of collegiate soccer to estimated training load and subjective measures of fatigue. Monitoring data from 21 male collegiate soccer players were retrospectively examined. Nine vertical jump sessions occurred across the season in addition to daily training load assessment and daily mood-state assessment. Group average changes from the first testing session were calculated and compared to the group average training load for the 7 days preceding each vertical jump testing session for static and countermovement jump height and allometrically scaled peak power. Statistical analysis demonstrated strong relationships between changes in vertical jump height for both conditions, allometrically scaled peak power for static jumps, and estimated training load. The results indicate changes in static jump height and allometrically scaled peak power may be more useful athlete fatigue monitoring tools than countermovement jump variables

Which history and physical findings are most useful in identifying rotator cuff tears?

It's unknown which -- if any -- historical factors are most useful, because no studies evaluating their accuracy with rotator cuff tears have been done. As for physical findings, no single physical examination finding is sensitive or specific enough to detect partial-thickness rotator cuff tears (strength of recommendation [SOR]: B, systematic review of lower-quality cohort studies)

Comparative Chemistry of Thermally Stressed North Lake and Its Water Source, Elm Fork Trinity River

To better understand abiotic dynamics in Southern reservoirs receiving heated effluents, water was analyzed before and after impoundment in 330 ha North Lake. Macronutrients, metals, and chlorinated hydrocarbons were measured. Concentrations of nutrients and metals in sediments were quantified in this 2 yr study. River water prior to impoundment contained 16 times more total phosphorus, and supported 23 times more Selenastrum capricornutum cells in an algal assay than reservoir water. The reservoir has essentially no drainage and since evaporation is high, the concentrations of many dissolved solids have increased since the reservoir was filled in 1958. North Lake is now phosphorus limited. Apparently altered chemical equilibria have caused precipitation or adsorption of phosphorus with calcium and iron

An Examination of Website Advice to Avoid Jury Duty

The use of a jury in legal proceedings can be traced as far back as the participatory democracies that emerged in Greece in the sixth century BC, although it was not until the signing of the Magna Carta that the right to a trial by a jury of one’s peers emerged.1 In the United States, the Sixth and Seventh Amendments of the U.S. Constitution expressly provide this right in both criminal and civil proceedings.2 Furthermore, these amendments provide individuals with the right to a trial before an impartial jury.3 This right intends to serve as a safeguard against unfair treatment during a trial, providing a system of checks and balances to pursue the goal that justice remains at the heart of the legal system. A jury is intended to serve as a cross-section of the community, as it is drawn from and purports to represent the collective community conscience and common sense when resolving disagreements.4 Despite this rich constitutional history and community context, many residents of the United States actively seek to avoid jury service when they are called, for reasons we discuss further below. Some individuals search the Internet for information about how to avoid participating in jury service. As trial judges are tasked with oversight that spans the entire process of impanelment through voir dire, this study sought to provide a contextual background to assist the judiciary in easily recognizing and assessing potential jury avoidance. In the current study, the investigators examined advice offered by popular websites about how reluctant jurors may attempt to be excused from jury service
