Educational Background and Industrial Experience of Industrial Arts Teachers in the State of Washington 1968-69

It was the purpose of this study to survey previous education and experience of industrial arts teachers of the junior and senior high schools in the state of Washington for the 1968-69 school year. This was accomplished utilizing the survey method. This study was undertaken in order to gain knowledge as to the qualifications of present industrial arts teachers. On the basis of results obtained, conclusions were reached which may assist educators in evaluating teacher qualifications as well as their own industrial arts program

thesisAnnually, 46 million patients, or 37% of patients seen in the emergency department (ED), receive laboratory testing in the U.S.; thus, making efficient lab order and result management critical to improving ED throughput, clinical efficacy, and safety. In order to manage labs and other processes, electronic emergency department tracking systems (EDTS) or electronic whiteboards have evolved features that support clinical, operational, and administrative needs. EDTSs have often augmented manual data entry with interfaces and/or integration with other systems such as registration, laboratory, radiology, and clinical information systems (CIS). One such integration evaluated in this study, EDTS/CIS context sharing, was added to automatically pass all necessary user, patient, and application parameters between the two systems in order to open the CIS lab module for a selected patient when the user is notified in the EDTS that laboratory test results for that patient are available for review. Therefore, context sharing eliminated multiple user steps needed to log-on, search, select, and navigate to the lab viewing module in order to view a patient's lab results. This study evaluates the effects of adding EDTS/CIS context sharing to an EDTS with lab notifications on ED process times. These effects were measured utilizing a pre- and post-intervention design for all ED encounters where specific common labs were resulted. A method of analyzing CIS audit logs in combination with EDTS and laboratory information system timestamps was implemented to measure patient management processes for quality improvement. After adding context sharing to lab notification features, the median interval between the availability of lab results and review of those results by the ordering provider decreased from 22.7 min., by 25% or 5.7 min. (p-value < 0.001), to 17.0 min. However, median time from resulting of labs to patient discharge were essentially unchanged, decreasing from 106.6 min. to 105.0 min. (p-value = 0.080). The proportion of lab results reviewed by physicians in the CIS integrated with the EDTS increased from 66% to 86% after the intervention (p-value < 0.001). EDTS/CIS context sharing and passive lab notification features improved the timeliness and completion of lab result review in the CIS and increased system adoption in this setting. However, reductions in the time intervals to review of lab results in the CIS did not result in an operationally or statistically significant improvement in time to discharge after the availability of results

Tools for success: understanding the efficacy of technology in Iowa community college English composition instruction

This study examines the uses and perceived effectiveness of technology in Iowa community college English composition instruction. A survey of those who teach English composition in Iowa community colleges and in-depth interviews with four instructors were conducted. The results show that community college English instructors use a wide variety of technologies in instruction and agree that technology use assists students during the various steps of the composing process. Instructors also said that technology can have a positive effect on some elements of the finished product, but that higher order concepts, including thesis development and creativity, are not enhanced by technology use. Instructors also were asked about their use of four specific technologies that the New Media Consortium\u27s Horizon Report, 2012 Higher Education Edition, suggests will come into widespread use in higher education instruction within the next three years. None of the four technologies the report identified (mobile apps, tablet computing, game-based learning, and learning analytics) were found to be commonly used for English instruction

Random Boolean Network Models and the Yeast Transcriptional Network

The recently measured yeast transcriptional network is analyzed in terms of simplified Boolean network models, with the aim of determining feasible rule structures, given the requirement of stable solutions of the generated Boolean networks. We find that for ensembles of generated models, those with canalyzing Boolean rules are remarkably stable, whereas those with random Boolean rules are only marginally stable. Furthermore, substantial parts of the generated networks are frozen, in the sense that they reach the same state regardless of initial state. Thus, our ensemble approach suggests that the yeast network shows highly ordered dynamics.Comment: 23 pages, 5 figure

Investigation of a Statistical Metric for Validation of a Structural Dynamics Model

Structural vibration is an important component of spacecraft launch and operation. Consequently, improved models have been developed to predict physical system responses during launch and operation. However, because model errors can be significant they are typically not used without first being accredited via validation methods. Model validation is the act of demonstrating the adequacy or accuracy of predictions of mathematical models for use within a specific area. This project investigates the effectiveness of a general statistical technique used to validate structural vibration models. To carry out this analysis we compare experimental and numerical responses by forming probabilistic representations for model predicted structural behaviors. From these distributions we calculate P-valued probability intervals used to recast the problem as a serious of Bernoulli experiments from which a minimum and actual validation score are derived. In order to execute this algorithm and determine the effectiveness of our vibration model a MATLAB module will be developed and implemented for a selected set of test data. The results will be compared to the conclusions of a more routine modal analysis comparison

The Rank of Recurrence Matrices

A recurrence matrix is defined as a matrix whose entries (read left-to-right, row-by-row) are sequential elements generated by a linear recurrence relation. The maximal rank of this matrix is determined by the order of the corresponding recurrence. In the case of an order-two recurrence, the associated matrix fails to have full rank whenever the ratio of the two initial values of the sequence is an eigenvalue of the relation
