Bucking the trend: part-time Master’s students at the University of Northampton

Nick Petford, Vice Chancellor of the University of Northampton, and Nick Allen, Executive Officer at the University of Northampton, explain how their institution has bucked the decline in part-time study for postgraduates and push the benefits of working with local industry partners on bespoke programmes

The misappropriation of “woke” : discriminatory social media practices, contributory injustice and context collapse

This article aims to give an analysis of the phenomena of unjust misappropriation of marginalised groups’ terms online, using the example misappropriation of ‘woke’ from the Black community on Twitter. I argue that using terms such as these outside their original context warps their meaning, decreasing the intelligibility of the experiences of the marginalised agents who use them when attempting to express themselves both within their community and without. I intend to give an analysis of this phenomena, with the expectation that understanding it better will provide a crucial step in combatting it. To this end, I argue it can be understood as a specialised form of what Kristie Dotson calls ‘contributory injustice’, injustices which involve the suppression of a marginalised community’s existing hermeneutical resources, combined with a specific consequence of what Boyd and Marwick call ‘context collapse’, the removal of social norms created through the homogenising effect of social media sites like Twitter. The result is a novel misappropriation phenomenon, I label ‘Context-Collapsed Contributory Injustice’ or ‘CC.CI’. This type of misappropriation is particularly harmful due to it being faster-acting than historical varieties of misappropriation. Furthermore, unchecked continual cases of CC.CI can cause a novel from of what Miranda Fricker calls ‘hermeneutical injustice’, which is demarcated from standard cases by its ability to reintroduce conceptual lacunas through undermining existing hermeneutical resources. I finish by disambiguating cases of CC.CI from natural meaning change and critically analysing some existing philosophical treatments of “woke”.Publisher PDFPeer reviewe

A highly scalable Met Office NERC Cloud model

Large Eddy Simulation is a critical modelling tool for scien- tists investigating atmospheric flows, turbulence and cloud microphysics. Within the UK, the principal LES model used by the atmospheric research community is the Met Office Large Eddy Model (LEM). The LEM was originally devel- oped in the late 1980s using computational techniques and assumptions of the time, which means that the it does not scale beyond 512 cores. In this paper we present the Met Office NERC Cloud model, MONC, which is a re-write of the existing LEM. We discuss the software engineering and architectural decisions made in order to develop a flexible, extensible model which the community can easily customise for their own needs. The scalability of MONC is evaluated, along with numerous additional customisations made to fur- ther improve performance at large core counts. The result of this work is a model which delivers to the community signifi- cant new scientific modelling capability that takes advantage of the current and future generation HPC machine

Quantifying research output on poverty and non-communicable disease behavioural risk factors in low-income and lower middle-income countries: a bibliometric analysis

Objectives Low-income and lower middle-income countries (LLMICs) bear a disproportionate burden of non-communicable diseases (NCDs). WHO has repeatedly called for more research on poverty and NCDs in these settings, but the current situation remains unquantified. We aimed to assess research output on poverty and NCD risk factors from these countries in relation to upper middle-income and high-income countries. Design Bibliometric analysis of primary research published between 1 January 1990 and 4 May 2017. We searched 13 databases, combining terms for poverty and NCD behavioural risk factors (tobacco, alcohol, diet and physical activity). Independent dual review was used to screen titles, abstracts and full papers. Two-tailed t-testing and multiple linear regression analyses were used to compare differences in means. Outcomes (1) Proportion of lead authors affiliated with institutions based in high and upper middle-income countries vs LLMICs. (2) Mean number of citations for publications from each region. (3) Mean journal impact factor for studies from each region. Results Ninety-one (67%) of the 136 included studies were led by scientists affiliated with LLMIC-based institutions. These authors represented 17/83 LLMICs (20%), and their studies garnered 4.8 fewer citations per paper than studies led by high-income and upper middle-income-affiliated authors; however, this finding was non-significant (P=0.67). Papers led by authors based in high-income and upper middle-income countries were published in journals with a mean impact factor 3.1 points higher than those from LLMICs (4.9 vs 1.7) adjusting for year of publication and number of citations (P<0.001). Conclusions Most poverty and NCD risk factor research is led by authors from a small number of LLMICs. These studies are being published in relatively low-impact journals, and the vast majority of LLMICs are not producing any research in this area that is vital to their social and economic development. The paucity of domestic evidence must be addressed to inform global policy

Not Alone: Tracing the Origins of Very Low Mass Stars and Brown Dwarfs Through Multiplicity Studies

The properties of multiple stellar systems have long provided important empirical constraints for star formation theories, enabling (along with several other lines of evidence) a concrete, qualitative picture of the birth and early evolution of normal stars. At very low masses (VLM; M <~ 0.1 M_sun), down to and below the hydrogen burning minimum mass, our understanding of formation processes is not as clear, with several competing theories now under consideration. One means of testing these theories is through the empirical characterization of VLM multiple systems. Here, we review the results of various VLM multiplicity studies to date. These systems can be generally characterized as closely separated (93% have projected separations Delta < 20 AU) and near equal-mass (77% have M_2/M_1 >= 0.8) occurring infrequently (perhaps 10-30%). Both the frequency and maximum separation of stellar and brown dwarf binaries steadily decrease for lower system masses, suggesting that VLM binary formation and/or evolution may be a mass-dependent process. There is evidence for a fairly rapid decline in the number of loosely-bound systems below ~0.3 M_sun, corresponding to a factor of 10-20 increase in the minimum binding energy of VLM binaries as compared to more massive stellar binaries. This wide-separation ``desert'' is present among both field (~1-5 Gyr) and older (> 100 Myr) cluster systems, while the youngest (<~10 Myr) VLM binaries, particularly those in nearby, low-density star forming regions, appear to have somewhat different systemic properties. We compare these empirical trends to predictions laid out by current formation theories, and outline future observational studies needed to probe the full parameter space of the lowest mass multiple systems.Comment: 16 pages, 7 figures, contributed chapter for Planets and Protostars V meeting (October 2005); full table of VLM binaries can be obtained at http://paperclip.as.arizona.edu/~nsiegler/VLM_binarie

INJURY INCIDENCE AND SEVERITY IN PROFESSIONAL BALLET DANCERS OVER THREE YEARS

A thesis submitted in fulfilment of the requirements of the University of Wolverhampton for the degree of Doctor of Philosophy.Although the benefits of exercise are well documented, the risk of injury as a result of exercise is also documented. The undertaking of exercise in the form of sport or dance carries a risk of injury. This risk is increased in the professional ranks where increased intensity of exercise coupled with greater exposure periods are noted.Two published systematic reviews of the literature pertaining to musculoskeletal injuries and pain in dancers (up to 2008) indicated that there are still major scientific limitations and biases in the literature reviewed and indicated the need for explicit criteria on injury definition and methods of injury reporting. The reviews did comment on the evidence that musculoskeletal injury is an important issue for all dancers and that there is preliminary evidence that comprehensive injury prevention and management strategies may reduce injuries. The purpose of this single cohort observational study was to document injury incidence and severity in professional ballet dancers over three years including any changes as a result of changes within their medical management. While it is recognised that a randomised control trial would be advocated for an interventional study, due to the demands of this high performance environment this was not feasible. As such, steps were taken to improve the reporting of findings through the utilisation of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement. To date there are two publications in peer reviewed journals as a result of the data collected in this study. In the absence of international consensus on injury data collection in dance the methodology employed in this study was consistent with the International Consensus Statements on injury data collection from sport. Although the incidence of injuries in Year 1 was lower than that in other sports, the results were higher than other studies that have been reported in dance. The reason for this may be due to the use of a more encompassing injury definition. In response to the data and details obtained through the injury audit process changes in the comprehensive medical management of the dancers were implemented. The pre-participation screening was extended and the individual conditioning programmes were structured using the developed Hybrid Intervention Model.The result of the injury auditing indicated a significant reduction in injury incidence in the Year 2, with a further reduction in Year 3. These findings support the results of the systematic reviews in that there is growing evidence that comprehensive injury prevention and management strategies may reduce injuries in dance and that in the absence of stronger evidence there is a strong recommendation for those charged with caring for professional dancers to implement comprehensive medical management programmes

Black House

Our memorial is called “The Black House”, and it has many rooms that symbolize the hardships of enslaved Africans who endured the Transatlantic Slave Trade. Savannah was the perfect place to place a memorial due to the incredibly high amount of people that were sold on auction there. Every year on March 2nd and 3rd, Savannah observes a “Weeping Time” to mourn for the 429 that were sold in 1859, making it the largest amount of people sold in one day. First, you enter through the back door into the kitchen which shows how enslaved women predominantly worked inside. Here, they took on roles such as cooks, cleaners, servants, and also were in charge of looking after the children. From there you move to the kid’s room, which hints at shocking details about the amount of enslaved children that were torn from their families. In the basement, you’ll find holding pens and chains used for holding enslaved Africans on their voyage across the Atlantic Ocean. They were imported by the United States from major contributors like Brazil, who alone was responsible for 40% of all slave trade. You exit the basement into a warm, inviting, and colorful living room that shows how life was for Africans before the slave trade began.https://csuepress.columbusstate.edu/historyfrombelow/1006/thumbnail.jp

Development of a method for measuring quasi-static stiffness of snowboard wrist protectors

In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to sprains or fractures. Wrist protectors are worn by snowboarders in an effort to reduce injury risk, by decreasing impact forces and limiting wrist hyperextension during falls. However, there is no international standard or universally-accepted performance specification that these products should conform to, resulting in an inability to judge which design elements offer the most protection. EN 14120:2003 prescribes requirements that roller sports wrist protectors should meet, and has been identified as a starting point for developing a snowboarding-specific standard. This paper critiques the EN 14120:2003 test protocol and goes on to present a mechanical test for assessing the ability of snowboard wrist protectors to resist extension of the hand under an applied load. A bespoke rig incorporating the hand/arm surrogate from EN 14120:2003 was mounted to a uniaxial test machine, and wrist protectors were strapped to the surrogate at a set tightness (tight, moderate, loose). Linear displacement of the uniaxial test machine was transferred to angular displacement of the hand via a galvanised steel cable passing through a low friction pulley. Linear displacement was set to 200 mm/min and force was measured at the load cell until 80 N was reached. The test, presented here, found that the ability of the protectors to limit hand extension was dependent on how tightly they were fitted to the surrogate; therefore, strap tightness must be accounted for during further wrist protector safety assessments. This test provides a repeatable way to characterise the ability of snowboarding wrist protectors to limit wrist extension

Effect of surrogate design on the measured stiffness of snowboarding wrist protectors

In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to ligament sprains or carpal and forearm bone fractures. Wrist protectors are worn by snowboarders in an effort to reduce injury risk, by decreasing peak impact forces and limiting wrist extension to prevent hyperextension during falls. There is no international standard or universally accepted performance specification that snowboarding wrist protectors should conform to, resulting in an inability to judge which designs offer the best protection. This study investigated how surrogate arm design affected the stiffness of wrist protectors during quasi-static mechanical testing. Three surrogate arms with increasing design complexity were used to test three wrist protectors. The results show that surrogate design does influence the stiffness of snowboarding wrist protectors. Given that the surrogate does influence protector performance, it is recommended that a standard surrogate design is established for research and product testing
