An Extension of the Theory of Job Embeddedness: An Investigation of Effects on Intent to Turnover of United States Air Force Members

This study investigated the ability of Mitchell, Holtom, Lee, Sablynski, and Erze\u27s (2001) job embeddedness construct to predict intent to turnover after considering the historical predictors of job satisfaction, organizational commitment, job search, and job alternatives. This study extended the research on job embeddedness by investigating the extent to which age, race, gender, and marital status would affect the relationship between job embeddedness and intent to turnover. Results indicated that job embeddedness was a significant predictor of intent to turnover. However, age, race, gender, and marital status were not found to be significant moderators of job embeddedness and intent to turnover

Aerodynamic characteristics of a 1/6-scale model of the rotor systems research aircraft with the rotors removed

A wind-tunnel investigation was conducted to refine the aerodynamic characteristics of the rotor systems research aircraft. For the investigation, a 1/6-scale model without a main rotor or a tail rotor was used. The model provided the capability for testing different engine nacelle sizes, engine pylon fairings, and tail configurations. The engine thrust effects were modeled by small engine simulators (fans). Data were obtained primarily over an angle-of-attack range from -13 deg to 13 deg at several values of sideslip. Stability characteristics and control effectiveness were investigated. The model with the scaled engine nacelles and the combination T-tail and lower horizontal tail displayed longitudinal and lateral-directional stability. Results show that by reducing the horizontal or vertical-tail span the longitudinal stability is decreased. Reducing the engine nacelle size increases the static stability of the model. Effective dihedral is essentially zero at 0 deg angle of attack and 0 deg wing incidence

Subsonic Flight Tests of a 1/7-Scale Radio-Controlled Model of the North American X-15 Airplane with Particular Reference to High Angel-of-Attack Conditions

An investigation of the subsonic stability and control characteristics of an unpowered 1/7-scale model based on the North American X-15 airplane was conducted by using a radio-controlled model launched from a helicopter and flown in free-gliding flight. At angles of attack below about 20 deg. where the model motions represent those of the X-15 airplane, the model was found to be both longitudinally and laterally stable, and the all-movable tail surfaces were found to be very effective. The model could also be flown at much higher angles of attack where the model motions did not necessarily represent those of the airplane because of slight geometrical differences and Reynolds number effects, but these test results are useful in evaluating the effectiveness at these angles of the type of lateral control system used in the X-15 airplane. In some cases, the model was flown to angles of attack as high as 60 or 70 deg. without encountering divergent or uncontrollable conditions. For some flights in which the model was subjected to rapid maneuvers, spinning motions were generated by application of corrective controls to oppose the direction of rotation. Rapid recoveries from this type of motion were achieved by applying roll control in the direction of rotation

Accounting education literature review (2017)

This review of the accounting education literature includes 103 articles published during 2017 in six journals: (1) Journal of Accounting Education, (2) Accounting Education, (3) Advances in Accounting Education: Teaching and Curriculum Innovations, (4) Global Perspectives on Accounting Education, (5) Issues in Accounting Education, and (6) The Accounting Educators’ Journal. We update 12 prior accounting education literature reviews by organizing and summarizing contributions to the accounting education literature made during 2017. Articles are categorized into five sections corresponding to traditional knowledge bases: (1) curriculum and instruction, (2) instruction by content area, (3) educational technology, (4) students, and (5) faculty. Research rigor of the empirical articles is discussed and critiqued. Suggestions for research in all areas are presented. Articles classified as instructional resources and cases published in the same six journals during 2017 are listed in appendices categorized by the relevant content area

Cyber-security in library & information science education

Information security (INFOSEC) includes confidentiality, access and authenticity, particularly of electronic information. INFOSEC has been studied extensively in computer science, business management and information systems, but not in library & information science (LIS). With the threats of cyber-terrorism, data loss, and overall reliance on electronic information, INFOSEC is, or should be, of great concern to LIS professionals and educators. This study explored a potential gap in the curricula of the LIS field. This exploratory research asked: to what extent are ‘security’ and ‘privacy’ explicit elements of ALA-accredited curricula; are there specific courses dedicated to these concepts; what courses overall include these concepts. Websites of all 56 ALA-accredited LIS programs were searched for explicit mention of the key words in any course description/catalog. These two keywords were chosen as being representative of the core concepts of INFOSEC, and as likely components of LIS curricula. Terms were searched individually and frequencies noted, as well as co-occurrences, across 16 course categories. Nearly one-third of the schools didn’t explicitly mention either keyword in course descriptions, and only 4 schools had specialized courses in security/privacy, particularly as meant by INFOSEC. The most frequent occurrence of “security” was in courses on computers/networking/Internet; the most frequent occurrence for “privacy” was in the area of law and policy. There were several course categories with no mentions for one or the other keyword. Initial findings indicate INFOSEC is not being widely addressed in LIS education and this topic needs further study

A data model of the Climate and Forecast metadata conventions (CF-1.6) with a software implementation (cf-python v2.1)

The CF (Climate and Forecast) metadata conventions are designed to promote the creation, processing, and sharing of climate and forecasting data using Network Common Data Form (netCDF) files and libraries. The CF conventions provide a description of the physical meaning of data and of their spatial and temporal properties, but they depend on the netCDF file encoding which can currently only be fully understood and interpreted by someone familiar with the rules and relationships specified in the conventions documentation. To aid in development of CF-compliant software and to capture with a minimal set of elements all of the information contained in the CF conventions, we propose a formal data model for CF which is independent of netCDF and describes all possible CF-compliant data. Because such data will often be analysed and visualised using software based on other data models, we compare our CF data model with the ISO 19123 coverage model, the Open Geospatial Consortium CF netCDF standard, and the Unidata Common Data Model. To demonstrate that this CF data model can in fact be implemented, we present cf-python, a Python software library that conforms to the model and can manipulate any CF-compliant dataset
