Tracking and data relay satellite fault isolation and correction using PACES: Power and attitude control expert system

The Power and Attitude Control Expert System (PACES) is an object oriented and rule based expert system which provides spacecraft engineers with assistance in isolating and correcting problems within the Power and Attitude Control Subsystems of the Tracking and Data Relay Satellites (TDRS). PACES is designed to act in a consultant role. It will not interface to telemetry data, thus preserving full operator control over spacecraft operations. The spacecraft engineer will input requested information. This information will include telemetry data, action being performed, problem characteristics, spectral characteristics, and judgments of spacecraft functioning. Questions are answered either by clicking on appropriate responses (for text), or entering numeric values. A context sensitive help facility allows access to additional information when the user has difficulty understanding a question or deciding on an answer. The major functionality of PACES is to act as a knowledge rich system which includes block diagrams, text, and graphics, linked using hypermedia techniques. This allows easy movement among pieces of the knowledge. Considerable documentation of the spacecraft Power and Attitude Control Subsystems is embedded within PACES. The development phase of TDRSS expert system technology is intended to provide NASA with the necessary expertise and capability to define requirements, evaluate proposals, and monitor the development progress of a highly competent expert system for NASA's Tracking and Data Relay Satellite Program

Recruitment, Retention, Job Satisfaction of Nurse Educators in Arkansas

Facing a crucial shortage of nurses and nurse educators, administrators of colleges and universities need to explore employment and individual characteristics that are related to recruitment and retention of nurse educators. Adding to the nurse and nurse educator shortage is the concern that the population of the United States is aging which creates a growing demand for more RNs. A further issue that complicates the nurse and nurse educator shortage is that nursing education is not producing enough RNs. Schools of nursing are positioned to have to prepare more new nurse graduates over the next decade in an effort to alleviate the nurse and nurse educator shortage. The purpose of this descriptive survey study was to describe individual and employment factors that attract nurses to academia and factors that permit nurses to remain in academia. Full-time nurse educators who teach in associate, baccalaureate, diploma, masters, and doctoral programs in Arkansas were surveyed. The survey was distributed to 209 nurse educators with 104 completed surveys returned. Results of the study indicated that autonomy and independence, balance with work and family life, teaching support, and administrative support were key indicators of job satisfaction. Nurse educators indicated that they are most likely to remain in academia if they have higher salaries, time off, and balance with work and family life. Additionally, nurse educators remarked that teaching, time off, and independence and autonomy as key indicators of recruitment to academia. Retirement, higher salary, and balance with work and family life were mentioned as reasons that nurse educators leave nursing education. Data analysis revealed no positive correlation between job satisfaction and reasons for leaving nursing education. Further study suggests exploring the influence of creating job satisfaction in the work environment as a resolution to recruitment and retention of nurse educators

The Essential Role of College and University Librarians in Supporting Transfer Student Success

Nationwide, the numbers of transfer students on college and university campuses are increasing; however, libraries have not fully recognized the unique needs of transfer students with respect to students\u27 attainment of information literacy competencies. Students may come to our campus with no previous information literacy instruction, and even if they had a library instruction class, it does not mean they can apply that to a new institution with different and perhaps more complex resources, or they may be taking online classes. Neither can we treat transfer students as First Time in College students, because they are not. Transfer students frequently experience transfer shock , which is defined as a drop in GPA post-transfer. Since information literacy is multi-disciplinary and essential to finding, applying and ethically using information, there is definitely a role for libraries to support the academic success of transfer students. By supporting transfer students we also support institutional initiatives often tied to performance-based funding. We will explore transfer student pathways beyond the traditional community-college-to-university path, challenges inherent in the transfer process and how libraries and librarians can support the academic success of this incredibly diverse group of students. The presenters are academic librarians; one at a large university and at one of the university\u27s large feeder colleges, and bring both personal observations as well as significant research to inform attendees

The Relationship Between Intra-Organizational And Inter-Organizational Coordination And Its Influence On Product Quality Improvement

A sample of 225 firms is analyzed, using structural equation modeling, to test five hypotheses.  This study seeks to gain a better understanding of the practice of coordination among functional areas within the buying firm as well as between buyer firms and their key suppliers.  The implications of this research suggest that it is important for firms to focus on their long-term success as they work with key suppliers.  The research shows when the stakeholders of the firm support its efforts to coordination and cooperation with its key suppliers, the firm benefits.  Evidence shows cross-functional coordination enhances the firm’s capability to cooperate with its key suppliers.  The findings are significant to supply chain manager and to the various functional managers in charge of quality, production, R&D, and customer service and their respective counter parts in supplier firms.  Finally, this study expands prior research and fills a gap in the literature by showing the importance of inter-organizational coordination between the buyer’s supply management/purchasing function and the supplier’s operations function. This study reveals that conformance to specifications, product reliability and overall product quality performance can be significantly improved when these inter-organizational functional areas coordinate their requirements.  The study also shows that product quality can be significantly improved when intra-organizational and inter-organizational coordination occurs simultaneously

Metabolic requirement of septic shock patients before and after liberation from mechanical ventilation

Objectives:Negative energy balance can impair regeneration of the respiratory epithelium and limit the functionality of respiratory muscles, which can prolong mechanical ventilation. The present study sought to quantify and identify the difference in energy expenditure of patients with septic shock during and upon liberation from mechanical ventilation. Methods:Patients admitted into intensive care with initial diagnosis of septic shock and mechanical ventilation-dependent were recruited. Their metabolic requirements before and after liberation from mechanical ventilation were measured by indirect calorimetry. A paired t-test was used to examine the variance between the two modes of breathing and a Spearman rho correlation coefficient to examine relationship of selected indicators.Results: Thirty-five patients, 20 males and 15 females mean age 69 ±10 years, body height of 1.58 ±0.08 meters, and ideal body mass 59.01 ±7.63 kg were recruited. Median APACHEII score was 22, length of stay in the intensive care was 45 ±65 days and duration on mechanical ventilation was 24 ±25 days. Measured energy expenditure during ventilation was 2090 ±489 kcal∙d-1 upon liberation from ventilation was 1910 ±579 kcal∙d-1 and actual caloric intake was 1148 ±495 kcal∙d-1. Measured energy expenditure (p=0.02), actual calories provision and energy expenditure with (p=0.00) and without (p=0.00) ventilator support were all significantly different. Mean carbohydrate oxidation was 0.17 ±0.09 g·min-1 when patients were on mechanical ventilation compared to 0.14 ±0.08 g·min-1 upon liberation, however, this difference was not statistically significant. Furthermore, mean lipid oxidation was 0.08 ±0.05 g·min-1 during mechanical ventilation and 0.09±0.07 g·min-1 upon liberation, which was also not statistically different. Comparison of carbohydrate utilization and lipid oxidation was not different during (0.7±0.36 vs 0.75±0.47 kcal·min-1) and upon liberation from mechanical ventilation (0.55±0.33 vs 0.78±0.59 kcal·min-1).Conclusions: This study examined energy expenditure and substrate oxidation within a single cohort of patients with and without mechanical ventilation. Measured energy expenditure was found to be higher during mechanical ventilation. The possible explanations were positive pressure support from ventilation, the repeated cycle of “rest” and “work” during weaning from ventilators and the asynchronization between self-initiated breathing effort and the ventilatory support. The change energy expenditure with and without ventilatory support should be monitored so that mismatch could be aligned. Future studies are important to examine whether matching energy expenditure with energy intake would promote positive outcomes.<br/
