Fine Motor Skills and the Occupations of Young Adults with Multiple Sclerosis
Objective: Multiple sclerosis (MS) is one of the most common neurological diseases affecting adults of working age, and those of younger ages of onset have been increasingly recognized. Twenty-seven percent of people with MS (PwMS) are age 30 years old or younger. The burden of MS for young adults puts them at risk for poorer outcomes regarding their education, family planning, vocation, and social skills as they transition to adulthood. Fine motor (FM) skill impairment might impede performance within the daily occupations of young adults who are transitioning into adulthood. Few studies focus on the occupations and occupational performance of younger adults with MS. Method: Forty participants with MS between the ages of 18 to 30 were recruited to participate in a study. Two standardized measures were used to identify possible FM dexterity deficits and one standardized self-report was used to measure the perceived satisfaction and performance of occupations for this population. A semi-structured interview was conducted with a subgroup of 18 participants to understand the lived experiences of young adults with MS (YAwMS) and their FM performance during their occupations. Results: With quantitative and qualitative analysis, a relationship was suggested between FM scores and both perceived performance and satisfaction scores of an adapted performance measure. Conclusion: Young adults with MS perceive difficulties with occupations that are influenced by their FM status. It is recommended that occupational therapy professionals consider the motor skill needed to perform and complete occupations that specifically require FM skills
Design of telemetry update for reaction wheel unit
Bradford Engineering is currently one of the top suppliers of reaction wheels in Europe. To be able to hold that position they need to improve the reaction wheels to meet more stringent requirements for future missions when it comes to stability of the wheel’s speed and communication capabilities.A part of the updates needed in the reaction wheel to meet these challenges is a re-definition of the Field Programmable Gate Array [FPGA] capabilities in their current Wheel Drive Electronics [WDE] module. My contribution in this one year project consisted of work on documentation for current running missions and to establish the baseline for the update needed in the code running in the FPGA.The work with documentation consisted of an update on documents that needed to be provided to the costumer, Astrium: Radiation Analysis, Reliability Prediction, Failure mode, effects, and criticality analysis [FMECA] and test procedures for the Reaction Wheel Unit [RWU] that is being used for qualifying purposes. This work had an additional value of providing me the necessary background about the product so that I could later work on the update of the FPGA.It was my task in the FPGA re design to evaluate the necessary changes that would be needed in the hardware so that an additional communication protocol is added, leaving enough capacity in the selected hardware to include an autonomous controller for wheel speed in the future. After this tradeoff on the hardware that needed to match the new requirements, I selected a new protocol interface so that it can be offered to the clients. This was later implemented in Very High SpeedIntegrated Circuit [VHDL].I did an additional study on the requirements for code development and I provided, together with this study, documentation explaining the steps needed to develop the code according to these requirements, so that once the full set of requirements is defined, the company could continue with the development, using the existing work.The overall result of a year of work at Bradford is a set of documents that I updated to meet the requirements of the costumer and a design on the new telemetry that can be used as the baseline for future versions of the RWU. The full design cycle is covered in the telemetry update, from definition of requirements to the verification using evaluation software. The whole process of VHDL design can be traced through the documents of the telemetry update that were provided
Managing Unconventional Oil and Gas Development as if Communities Mattered
The advent of horizontal oil and gas drilling into relatively impermeable shale rock, and the companion technological breakthrough of high-pressure, multi-stage fracking that frees hydrocarbons along the substantial length of these horizontal wells, has fundamentally altered the oil and gas industry. The Energy Information Administration has gone so far as to predict that North America could become a net energy exporter as early as 2019, largely as a result of the explosive growth of this “unconventional” oil and gas development. Despite its promise, managing unconventional oil and gas development has proved challenging, and many of the communities that find themselves hosting this development have begun to push back in the face of serious public health and community impact concerns. Some communities have gone so far as to enact complete bans on “fracking,” the shorthand way that unconventional development is often described. Yet notwithstanding many legitimate concerns, the flexibility made possible by drilling wells horizontally two, three, and even five miles in length provides an opportunity to manage unconventional oil and gas development in a manner that greatly reduces health and environmental impacts.
Efforts to impose proactive management regimes that would effectively address these adverse impacts have thus far proved elusive. Effective management was especially challenging when the prices for oil and gas were high and developers rushed to cash in. But as the price of these commodities collapsed, and as development has waned, an opportunity has emerged to forge a new dialogue over a smarter approach to unconventional oil and gas development that might be deployed when the inevitable boom mentality returns. A smarter approach recognizes that the flexibility afforded by horizontal drilling can minimize the adverse impacts of development even while making development more efficient.
Many in the industry will likely resist a system that requires a far more substantial role for regulatory agencies, especially during the planning phase of development. But once the affected parties understand that oil and gas development can be carried out in a manner that is both efficient and compatible with community health and values, then the prospects for a productive relationship should brighten. Let the hard work of building that relationship begin
