Not Just an Ache: Examining the Rate of Musculoskeletal Pain in City Bus Drivers

This paper examines the rates of musculoskeletal discomfort in a sample of 957 city bus drivers at King County Metro, a public transportation agency serving the greater Seattle area. It also examines how often such pain prevented drivers from doing their normal work, needed treatment from a medical professional, or incited one or more worker’s compensation claims. To assess the level of musculoskeletal discomfort in city bus drivers, an anonymous survey was distributed to drivers at King County Metro, a public transportation agency serving the greater Seattle area. This survey consisted of a Nordic Questionnaire asking drivers whether or not they experienced pain in certain areas of the body in the past twelve months, along with a small section asking for basic information such as age, hours per week worked, and gender. The results of the survey demonstrate that bus drivers experience very high rates of musculoskeletal pain, with 85% of respondents indicating pain in at least one area of the body. Comparisons to CDC data show higher rates of musculoskeletal pain in this sample than in the general population. Female and full-time drivers showed consistently higher rates of pain across all areas of the body then their male and part-time counterparts, while variables such as BMI and age showed less influence. Rates of pain in the lower back, shoulders, and knees were especially elevated. Of those experiencing pain in at least one area of the body, more than 50% were prevented from doing their normal work and visited a medical professional. For all drivers experiencing pain, there were large gaps in the rates of medical visits and worker’s compensation claims. Policy recommendations include the provision of active-suspension seats in the agency’s fleet of buses and better placement of key controls in the drivers’ workstation, two goals potentially attainable through increased participation of drivers in the bus-procurement process. The role of different route types, stop placement patterns, and road surfaces in addressing rates of musculoskeletal pain in bus drivers should also be investigated

Open access in Australia: an odyssey of sorts?

Scholarly communication change and open access (OA) initiatives in Australia have followed an Odyssean path in the last decade. The stop-start nature of early initiatives demonstrates that institutional leadership is essential for the successful deposit of academic content in an institutional repository. Similarly, OA policies from the two Australian Research Councils were delayed for nearly a decade, partly due to publisher pressure and bureaucratic conservatism. More successful has been the development of full, or hybrid, open access university e-presses. These presses, usually embedded in the scholarly infrastructure of the university, provide monographic models for wider global consideration. Australian universities are now reflecting, partly through recent Research Council edicts and monitoring global OA developments, greater awareness of the need for action in scholarly communication change Journal: Insights 26.3 (2013): 282-28

Device for diode tuning in a stripline varactor harmonic multiplier

Stripline varactor harmonic multiplier uses a device for positioning the varactor diode with respect to the stripline circuit to obtain series resonance. The device also reduces detuning effects, due to thermal expansion, over a wide temperature range

Examination of Molinism

What is the driving force behind salvation? Is it God’s sovereign will, enacting His efficacious grace upon the heart of man? Or is it the free will of man himself, choosing to accept the grace that has been extended to him? This is the age-old question behind the argument of sovereignty versus free will. Luis de Molina, a sixteenth century Jesuit theologian, believed that God, through His omniscience and omnipotence, can predestine an individual for salvation while keeping the free will of that individual intact. This system, known as Molinism, stands on three main principles: a wholly libertarian account of man’s free will, the conviction that the grace the Lord extends to complete salvific acts is not in itself intrinsically efficacious, and the assumption of the truth of the concept of Scientia media, or Middle Knowledge
