Vibration responses of test structure no. 1 during the Edwards Air Force Base phase of the national sonic boom program

In order to evaluate reaction of people to sonic booms of varying overpressures and time durations, a series of closely controlled and systematic flight test studies were conducted in the vicinity of Edwards AFB, California, from June 3 to June 23, 1966. The dynamic responses of several building structures were measured as a part of these studies, and the measurements made in a one-story residence structure (Edwards test structure No. 1) are presented. Sample acceleration and strain recordings are presented from F-104, B-58, and XB-70 sonic-boom exposures, along with tabulations of the maximum acceleration and strain values measured for each one of about 140 flight tests. These data are compared with similar measurements for engine noise exposures of the building during simulated landing approaches and takeoffs of KC-135 aircraft

Vibration Responses of Test Structure No. 2 During the Edward Air Force Base Phase of the National Sonic Boom Program

In order to evaluate reaction of people to sonic booms of varying overpressures and time durations, a series of closely controlled and systematic flight tests/studies were conducted from June 3 to June 23, 1966. The dynamic responses of several building structures were measured, with emphasis on a two-story residence structure. Sample acceleration and strain recordings from F-104, B-58, and XB-70 sonic boom exposures are included, along with tabulations of the maximum acceleration and strain values measured for each one of about 140 flight tests. These data are compared with similar measurements for engine noise exposures of the building during simulated landing approaches and takeoffs of KC-135 aircraft

A more interdisciplinary approach can help us understand why research evidence does or doesn’t make it into policy

Effective communication of research is often cited as being most important to gaining the attention of policymakers. This arguably underestimates the sheer complexity of the policymaking process, assuming a linear route from evidence to policy and practice. Fiona Blyth and Carmen Huckel Schneider explain why breaking down walls between different academic disciplines could enhance our understanding of why research evidence does − or doesn’t − make it into policy, and also suggest questions that researchers might ask as a “gateway” to understanding these different approaches to evidence-informed policymaking

Experiences of registered nurses in a general practice-based new graduate program: A qualitative study

Nurses are increasingly needed in primary healthcare settings to support community-based healthcare delivery. Programs to facilitate transition of new graduate nurses are well established in acute care however, there are few similar programs reported in settings like general practice. This paper sought to explore the experiences of new graduate registered nurses and their registered nurse mentors in a new graduate program within Australian general practice. New graduates (n = 9) and their mentors participated in interviews before, during and at the conclusion of a 12-month new graduate program. Interviews were digitally audio-recorded and professionally transcribed verbatim before being analysed using thematic analysis. Eighteen new graduate and 10 mentor interviews were conducted, revealing four themes. Preparation and Opportunities describes the influence that pre-registration education had on preparing nurses for general practice employment. Exceeding Expectations highlights the positive experiences within the program. Program Challenges draws attention to the difficulties experienced by participants, and Future Career Intentions explores future career plans. This study highlights that a general practice new graduate nurse program has the potential to build the workforce. However, strengthening undergraduate preparation of nurses around primary health care and addressing funding issues in general practice, are important to promote the success of such programs
