The manual process for flight scheduling at Naval Air Station Lemoore accommodates the needs of 16 fighter resident squadrons as well as constraints imposed by limited military operating area availability. Given the complexity of this problem, attempting to additionally avoid periods of high activity and resultant congestion would challenge the manual process. However, congestion leads to long wait times for flight-line services. Refueling operations are particularly costly when operational time is lost, and resources are backlogged. The problem of avoiding inefficient periods of high demand is complicated by the two types of refueling available: hot refueling, which occurs when the aircraft's engine is running, and cold refueling, which occurs when the aircraft is shut down. Achieving a balance between the two refueling methods is key to maximizing operational effectiveness. The authors discuss an optimization model designed to determine the best daily flight schedules based on the squadrons' flying and training requirements, the refueling infrastructure, and range availability.

Introduction: Careful selection and timely activation of clinical sites in multicenter clinical trials is critical for successful enrollment, subject safety, and generalizability of results. Methods: In the Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2), a multidisciplinary Site Selection Committee evaluated applicants referred via participation in CREST, CREST principal investigators (PIs) and other investigators, StrokeNet and industry partners. Data for consideration included performance metrics in CREST and other carotid trials and a site selection questionnaire containing information on the investigators as well as quantitative data on carotid procedures performed. Any FDA warning letters were reviewed. Results: The Committee met bi-weekly for 36 months (n=64 meetings). Applications from 176 sites between March 2014 and July 2016 were evaluated: 153 were approved, 7 are under Committee review, 5 were approved but withdrew, 5 were placed on a waiting list, and 6 were rejected. One-hundred-four sites have completed the regulatory and training requirements to randomize: 51 (49%) academic medical centers, 31 (30%) private hospital-based centers, 16 (15%) private office-based practices, and 6 (6%) Veterans Administration medical centers. The mean times from application-to- approval was 5.2 weeks (interquartile range, 1.9, 6.2), and from approval-to-randomization status was 46.7 weeks (interquartile range, 35.4, 51.7). Specialties of the 104 site PIs are vascular surgery for 35 (33.7%), cardiology for 30 (28.8%), neurology for 25 (24%), neurosurgery for 8 (7.7%), interventional radiology for 4 (3.8%), and interventional neuroradiology for 2 (1.9%). Conclusions: Careful site selection is time-consuming for prospective sites and for trial leadership. Times from application-to-site-approval were modest (mean = 5.2 weeks), in contrast to the times for completing regulatory and training requirements (mean = 46.7 weeks). However, subject enrollment by teams from a wide range of medical centers led by a multi-disciplinary cohort of PIs will promote the generalizability of trial results.

In 2010, the Arizona legislature effectively deregulated concealed handgun carry in the state by passing Senate Bill (SB) 1108, which eliminated licensing and training requirements for concealed carry. Although researchers have extensively examined the impact of state adoption of concealed carry laws, almost nothing is known about the effects of deregulating concealed carry altogether. This study contributes to the more guns, less crime debate by examining the impact of Arizona’s decision to deregulate concealed carry. Using a multiple time-series research design with an experimental (Tucson) and control city (El Paso), the present study examines the impact of deregulation on handgun-related violent crime and gun larcenies in Arizona’s second largest city—Tucson. We find that the passage of SB 1108 had no impact on handgun-related offenses that could be expected to change following deregulation. The implications of these findings for policy making and future research are discussed.

Objective: To poll members of the Pharmacy Technician Educators Council (PTEC) to determine their attitudes toward the level of education and training necessary for pharmacy technicians to perform current and expanded duties. Methods: A convenience survey was developed and sent to 130 PTEC member training programs. PTEC members include directors of college, vocational, and on-the-job training programs. Results: Thirty-seven PTEC members responded, yielding a response rate of 28.5%. Responses reflected the opinions of directors of pharmacy technician programs from 19 states. All respondents agreed that the length of training for pharmacy technicians should be standardized. They also agreed that minimum competencies should be established for pharmacy technicians and that examination should be required to obtain certification or licensure that would then enable the technician to be employed in the field. Conclusions: The use of pharmacy technicians will likely increase, as will the duties pharmacy technicians perform. Expansion of the role of pharmacy technicians, however, must be in tandem with standardizing training and establishment of competencies for pharmacy technicians. Increased responsibilities should be commensurate with increased education and national examination should be required to determine competency.

A decisive economical factor in the business transformation project (BTP) of a traditional business environment (BE) into an automated business environment, is the profile of the business transformation manager (BTM), who should be supported by a framework (Trad, & Kalpić, 2001; ). The BTM's profile and its relation to enterprise business architecture skills, have an ultimate impact on the concrete implementation phase of business transformation and related enterprise architecture projects. The basic profile and managerial aspects of BTM profiles and its support, have not been sufficiently researched, to hammer an optimal profile and a corresponding supporting framework that is why this research article proposes the related BTP's managerial recommendations and conclusions. This research paper and the related research publications series deals with the BTP's support for the BTM's selection, architecture support, decision making and training requirements; where the BTM, has to manage the complex technical implementation phase of the BTPs; knowing that this phase of a BTP is the major cause of very high failure rates.

Some of the results of an extensive study on selection and training of computer systems analysts are reported. Special attention is devoted to a job description and job analysis as a basis for identifying the critical attributes and training requirements involved. The development and validation of a battery for the selection of computer systems analysts and students of computer science are discussed.
