Elf: computer automation and error correction for a microwave network analyzer

A microwave measurement system has been developed that combines a personal computer (PC) and an conventional vector network analyzer to yield a full complex-error-corrected automatic network analyzer. The system consists of a Hewlett-Packard HP 8410C network analyzer, an HP 8350B sweep oscillator, and an IBM PC. A program called Elf runs on the PC, performing calibration and measurement algorithms and providing a flexible, menu-oriented user interface. The system, when calibrated, achieves a worst-case measurement error vector of magnitude ≤ 0.02 for transmission and reflection coefficient measurements over the 2-12.4-GHz frequency range and has a measurement speed of three frequency points/s. Elf provides an inexpensive method for upgrading the HP 8410 to achieve the high accuracy of an automatic network analyzer

Puff, an Interactive Microwave Computer Aided Design Program for Personal Computers

We will demonstrate a CAD program designed for the lay out and analysis of microstrip circuits. The program runs on the IBM PC or AT. Circuit elements are selected from a parts list and drawn on the screen using the cursor keys. The analysis may then be performed, directly from the screen drawing. Puff has been used by microwave students in classes at the California Institute of Technology and the University of California at Los Angeles

Treatment of Chronic Pain in U.S. Veterans: The Effectiveness of Interdisciplinary Programs

Chronic pain is a prevalent issue amongst US veterans. Experts suggest that interdisciplinary pain treatment is the most effective method of treating chronic pain, specifically due to targeting functioning and quality of life. These programs combine cognitive behavioral therapy and physical therapy by utilizing a variety of exercise and education regimens. The pain department at Columbia VA Health Care System offers both a comprehensive interdisciplinary treatment, Outpatient Interdisciplinary Pain Program (OIPP), and a flexible, multidisciplinary option (OIPP-Lite) for veterans suffering from chronic pain. The goal of this program is to improve knowledge for coping with chronic pain and to create a better quality of life in regard to both physical and mental health. This study was designed to examine the effectiveness of the programs. Although the multidisciplinary program (OIPP-Lite) offers flexibility and is less taxing on veteran and administration resources, preliminary examination would suggest that the interdisciplinary approach (OIPP) offers more effective treatment. Data collection included behavioral health measures, physical therapy measures, knowledge gains, and patient histories to determine changes in the amount of pain-related medical visits. These measures were conducted upon program entry, program completion, and 3- and 6-month follow up appointments. Data was then analyzed by comparing the initial measures between both OIPP and OIPP-Lite and then comparison between post-OIPP measures, 3-month, and 6-month follow ups. Statistical testing was conducted by using a t-test to compare between the separate data groups, leading to the determination that the group composition of initial measures for each program are relatively comparable. Veterans were given the option to participate in either OIPP or OIPP-Lite based on personal preference. For the purpose of this study, 112 participants of both OIPP and OIPP-Lite were analyzed. Due to difference in program duration, there were twice as many OIPP cohorts compared to OIPP-Lite. Common age groups included the age ranges of 41-65 and 66-85, with 86% of participants being males. The common diagnoses of participants included back, arm/leg, and neck pain, depression, and insomnia. It was hypothesized that an interdisciplinary program (OIPP) would produce more effective gains in quality of life and physical gains than a multidisciplinary approach (OIPP-Lite). While both see general positive growth in scores, OIPP had larger improvements on average despite having worse initial symptoms. Both programs demonstrated significant increase in veterans’ knowledge of pain management and improvements in pain catastrophizing, depression, and the number of pain-related medical visits. Only OIPP revealed significant improvements in sleep hygiene. However, OIPP-Lite utilizes fewer VA resources and is more efficient to offer to participants. Additional information concerning veteran satisfaction is desired to create a conclusive choice between OIPP and OIPP-Lite. It is recommended for VHA to consider continuing both programs to effectively address the needs and preferences of the veterans served

THE EFFECTS OF A NEW METHOD OF INSTRUCTION ON THE PERCEPTIONS OF APPALACHIAN ENGLISH

This paper evaluates whether students’ perceptions of Appalachian English improve through a method of instruction that uses dialect literature in the classroom. Most existing methods of instruction tend to portray dialects as wrong, incorrect, or in some way less rule-governed than Standardized English, despite the numerous studies that have demonstrated otherwise (e.g., Labov 1969, Wolfram 1986). The data from this study derives from two groups of students enrolled in introductory composition and communication at the University of Kentucky. Each group is given a pre-test to determine attitudes toward Appalachian English and Standardized English. An experimental group is then exposed to a method that incorporates texts that use Appalachian English features, while no specific dialect literature is included in the control group. After the conclusion of the lessons, students in both groups complete a post-test used to analyze whether their perceptions of Appalachian English changed throughout the study. The experimental method results in significant increases in several of the attitude measures for Appalachian English, while the students that did not receive this method of instruction experienced no increase for the linguistic variety. These results demonstrate that this method has potential for reducing negative perceptions towards speakers of non-standard dialects

Personal Protective Equipment Use for Patients with Clostridium difficile

In researching the literature on correct PPE by healthcare staff when a patient has C. diff. I have found that the policy on PPE for patients with C. diff at Baptist Health Paducah is compliant. The theoretical framework used for this research is that of Imogene King. Their policy is evidence based and is also cost effective when it comes to preventing the spread of infection from patient to patient. There is no need for change to this policy at this time because it is supported by evidence in the literature
