Projected speciality career choices amongst undergraduate dental students in Scotland

Background: Despite increased numbers of dental specialists, around 90% of dentists in the UK continue to work in general practice. Previous research shows that undergraduate students indicate interest in speciality careers, however few studies have explored which specialties are of interest, when and why. The aim of this study was to explore whether Bachelor of Dental Surgery (BDS) undergraduates attending Glasgow Dental School (GDS) indicate a desire to pursue a speciality career, why, and the extent to which they feel prepared in this regard. Method: We conducted an internet-based survey (response rate 81%; n = 331) of all GDS students between October and November 2016. Results: One hundred and eighty-six students (56%) had decided to specialise. Seventy-eight percent of these students cited enjoyment of that service, or types of patient seen, as the single most influencing factor on their choice. Oral surgery was the most popular choice where one was indicated (35%), followed by orthodontics (26%). Just 14% of BDS4-5 students felt sufficiently exposed to cases in their chosen speciality. A large majority (88%) said they would like information regarding speciality pathways at BDS3 or before. Conclusions: Educators should provide undergraduate students with information about specialties in a structured way, so that they can consider available options

Voluntary activation of human knee extensors measured using transcranial magnetic stimulation

The aim of this study was to determine the applicability and reliability of a transcranial magnetic stimulation twitch interpolation technique for measuring voluntary activation of a lower limb muscle group. Cortical voluntary activation of the knee extensors was determined in nine healthy men on two separate visits by measuring superimposed twitch torques evoked by transcranial magnetic stimulation during isometric knee extensions of varying intensity. Superimposed twitch amplitude decreased linearly with increasing voluntary torque between 50 and 100% of mean maximal torque, allowing estimation of resting twitch amplitude and subsequent calculation of voluntary activation. There were no systematic differences for maximal voluntary activation within day (mean ± S.D. 90.9 ± 6.2 versus 90.7 ± 5.9%; P = 0.98) or between days (90.8 ± 6.0 versus 91.2 ± 5.7%; P = 0.92). Systematic bias and random error components of the 95% limits of agreement were 0.23 and 9.3% within day versus −0.38 and 7.5% between days. Voluntary activation was also determined immediately after a 2 min maximal voluntary isometric contraction; in four of these subjects, voluntary activation was determined 30 min after the sustained contraction. Immediately after the sustained isometric contraction, maximal voluntary activation was reduced from 91.2 ± 5.7 to 74.2 ± 12.0% (P < 0.001), indicating supraspinal fatigue. After 30 min, voluntary activation had recovered to 85.4 ± 8.8% (P = 0.39 versus baseline). These results demonstrate that transcranial magnetic stimulation enables reliable measurement of maximal voluntary activation and assessment of supraspinal fatigue of the knee extensors

A comparison of theory and practice in market intelligence gathering for Australian micro-businesses and SMEs

Recent government sponsored research has demonstrated that there is a gap between the theory and practice of market intelligence gathering within the Australian micro, small and medium businesses (SMEs). Typically, there is a significant amount of information in literature about 'what needs to be done', however, there is little insight in terms of how market intelligence gathering should occur. This paper provides a novel insight and a comparison between the theory and practices of market intelligence gathering of micro-business and SMEs in Australia and demonstrates an anomoly in so far as typically the literature does not match what actually occurs in practice. A model for market intelligence gathering for micro-businesses and SMEs is also discussed

Open Space Acquisitions and Management Opportunities in the City of Atlanta and Adjacent Jurisdictions

The great cities of the world are distinguished by their public parks. The urban fabric of New York, Barcelona, Berlin, Moscow, Paris, Rome, Sydney, and Shanghai are all woven around great parks. Yet, with all of Atlanta's outstanding achievements, the City and the region have a notably undistinguished park system. In a study conducted by the Trust for Public Land and the Urban Land Institute, Atlanta ranks near the bottom of the nation's largest 25 cities in acreage of parkland per capita with 7.3 acres for every 1,000 residents. Compare that to Austin, Texas' 39 acres per 1,000 residents or Oklahoma City's 43 acres per 1,000 residents and it becomes clear that something is amiss in metro Atlanta.This study identifies the obstacles to acquiring and maintaining open and green spaces in the metro Atlanta region. Addressing open space shortages in metro Atlanta is a sizable task. This study could be considered the first step in a larger process. Time spent researching the various obstacles and opportunities regarding open space acquisition raised many questions that are beyond the scope of this project. A second phase might test the recommendations made in this phase by working with local officials on a few select projects, and begin to identify critical pieces of property in metro Atlanta that must be protected from development. A detailed inventory of significant open space and natural resources in the metro area that includes the existing inventory of land inside of Interstate 285 should be considered either as a separate study or included in this recommended second phase

An Optimal Trade-off between Content Freshness and Refresh Cost

Caching is an effective mechanism for reducing bandwidth usage and alleviating server load. However, the use of caching entails a compromise between content freshness and refresh cost. An excessive refresh allows a high degree of content freshness at a greater cost of system resource. Conversely, a deficient refresh inhibits content freshness but saves the cost of resource usages. To address the freshness-cost problem, we formulate the refresh scheduling problem with a generic cost model and use this cost model to determine an optimal refresh frequency that gives the best tradeoff between refresh cost and content freshness. We prove the existence and uniqueness of an optimal refresh frequency under the assumptions that the arrival of content update is Poisson and the age-related cost monotonically increases with decreasing freshness. In addition, we provide an analytic comparison of system performance under fixed refresh scheduling and random refresh scheduling, showing that with the same average refresh frequency two refresh schedulings are mathematically equivalent in terms of the long-run average cost
