Belyi-extending maps and the Galois action on dessins d'enfants

We study the absolute Galois group by looking for invariants and orbits of its faithful action on Grothendieck's dessins d'enfants. We define a class of functions called Belyi-extending maps, which we use to construct new Galois invariants of dessins from previously known invariants. Belyi-extending maps are the source of the ``new-type'' relations on the injection of the absolute Galois group into the Grothendieck-Teichmuller group. We make explicit how to get from a general Belyi-extending map to formula for its associated invariant which can be implemented in a computer algebra package. We give an example of a new invariant differing on two dessins which have the same values for the other readily computable invariants.Comment: 13 pages, 7 figures; submitted for publication; revisions are that the paper now deals only with Galois invariants of dessins, and that material is slightly expande

Developing a workbook for primary care nursing students

There is a continuing need to prepare a nursing workforce that is adaptable within a range of care settings. The faculty of health at Staffordshire University seconded a lecturer practitioner for a 12-month period to conduct an audit on primary care placements. Mentors were involved in the audit in order to include their views and opinions alongside those of students

The impact of the formal equality stance on institutional processes and legal compliance in Higher Education

The aim of this paper is to build on a previous paper which explored the politics and perspectives of various social actors regarding anti-discrimination legislation and equality within a higher education setting. This paper will discuss the impact of the politics and perceptions on compliance with legislative requirements as reflected through the equality processes within a case study institution. In considering this, the question which will be borne in mind is: does the tendency towards adopting the formal equality stance also impact on the case study’s equality processes and, in turn, their response to the Public Sector Equality Duty (PSED)? Such an analysis could have wider implications on how equality and compliance with the law is dealt with in other Higher Education Institutions (HEI)

Understanding quality in inclusive research: a process of dialogue

The case for research by and with (rather than on) people with learning disabilities has been successfully made. Calls for emancipatory research have drawn attention to the ways that research owned by disabled people can better tackle social oppression. For learning disabled people moves towards a productive rather than passive role in research have largely retained some involvement of non-disabled people. This paper reports on a study in England which brought together learning disabled researchers leading their own research, learning disabled and non-disabled researchers working in collaborative research partnerships, and academic researchers using participatory design or methods. We adopted Walmsely and Johnson’s (2003) concept of inclusive research to recognise the overlaps between emancipatory and participatory research and the need for research that matters to the people involved, represents their views, involves them in the research process, treats them with respect, and may improve their lives. The intention was to work together in a series of focus group discussions to take stock of what we had learned about doing inclusive research and to answer Walmsley and Johnson’s call to ‘grapple honestly’ with the challenges. This is necessary if quality in inclusive research is to be understood. In the paper I reflect on the research process and the resulting model of ways of researching together and guidance in the form of questions to ask ourselves: when judging the quality of inclusive research; when negotiating how to work together in inclusive research; and when using the case study materials the project generated

Effect of Heat-Treatment Time on Bending Properties of Cobolt-Chromium Orthodontic Wires

Different protocols appear in the literature with respect to heat-treating cobalt-chromium orthodontic wires. The objective was to determine the effect of variable heat-treatment time and method on the bending properties of CoCr wires. Two tempers of CoCr ‘Elgiloy’ wires (Rocky Mountain Orthodontics), blue (B) and yellow (Y), were heat-treated for different durations. The groups (n=20/group/temper) included: 1) as-received (control); 2) brush-flame; 3) 480oC for 5sec; 4) 480oC for 10min; 5) 480oC for 2hr; and 6) 480oC for 5hr. Wire segments were tested by a three-point bend test. Stiffness/flexural modulus, percent recovery, and force values at select deflections were statistically compared using ANOVA/Bonferroni post-hoc test (p\u3c0.05). A T-test compared the different tempers. Longer heat-treatment (2hr/5hr) increased % recovery, flexural modulus, and force values when compared to the as-received counterparts. Heat treatment for 10 minutes resulted in intermediate increases. Using a brush-flame technique reduced elastic recovery and resulted in greater bending variability. Similar mechanical properties can be achieved in just 2 hours compared to the manufacturer recommended 5 hours of heat-treatment of Elgiloy wires. Ten minutes of heat-treatment, which may be more realistic in a busy orthodontic practice, can increase bending properties 50-75% compared to the 5-hour group. The brush-flame technique is not recommended due to inconsistent heating conditions resulting in varying bending properties

Project 150

Project 150 is designed to provide for homeless high school students. It was established in December of 2011 they provide teens with meal bags and school supplies.https://digitalscholarship.unlv.edu/educ_sys_202/1059/thumbnail.jp
