Becoming a teacher educator : guidelines for induction : 2nd edition

The first edition of these guidelines was published in 2007. Since that date it has been used to support the induction of new teacher educators in the UK and beyond. The guidelines and the research which underpinned them also won the Sage BERA Practitioner Research Prize in 2009. But change in the higher education sector and in the field of teacher education mean that the time is now right for a second edition. This new edition has been revised in four main ways. Firstly, a considerable body of published international research focused on teacher educators has been produced since 2007 and the revised guidelines are informed by this work. Secondly, the new guidelines include the ‘voices’ of new teacher educators themselves gathered during our regular workshops for new teacher educators and our research projects. Thirdly, the revised edition aims to be more inclusive of all teacher educators, including those in further education. In terms of this latter group, it is informed by the limited literature available and our own research into the experiences of those teaching higher education programmes in further education colleges. Finally, the new guidelines seek to respond in a measured way to changing policy and contextual frameworks. These include the continued intensification and increasing fragmentation of academic work and identity in the higher education sector; and the wider questioning of the contribution of higher education to professional education for teachers

Rearing calves outdoors with and without calf jackets compared with indoor housing on calf health and live-weight performance

peer-reviewedThe objective of this study was to compare the effects of rearing calves outdoors, with and without all-weather calf jackets, with calves reared indoors on calf immunity and animal performance. In February 1999, male Holstein calves (mean (s.e.) weight 55 (1.90) kg) were randomly assigned to one of three treatments (n=30 per treatment): 1) outdoors with jacket, (J; mean age 19 (s.e. 2.0) days); 2) outdoors without jacket (NJ; mean age 19 (s.e. 1.8) days), and 3) indoors on straw (I; mean age 19 (s.e. 1.0) days). Calves received an individual allowance of 25 kg of milk replacer dry matter during the first 42 days with ad libitum access to a concentrate ration from day 0 to 63. The jackets were removed from the calves on day 42. Live-weight gain from day 0 to day 63 of the study was not significantly different between treatments (J, 0.79; NJ, 0.80; I, 0.80 kg). Sixty percent of the J calves and 53% of the NJ calves required four or more antibiotic treatments for respiratory disease while corresponding treatments were required for 97% of the I calves. The incidence of diarrhoea was significantly higher in both outdoor treatments compared to the I treatment. There was no significant difference in white blood cell counts or in serum immunoglobulin concentrations between treatments on days 0, 21, 42 and 63 or in in vitro interferon-γ production on day 63. It is concluded that using calf jackets on calves reared outdoors had no beneficial effect on calf performance or immune status. The incidence of respiratory disease was higher and diarrhoea incidence was lower in calves reared indoors compared with calves reared outdoors. There was no significant difference in incidences of diarrhoea and respiratory disease between the two outdoor treatments

A microscopic approach to nonlinear Reaction-Diffusion: the case of morphogen gradient formation

We develop a microscopic theory for reaction-difusion (R-D) processes based on a generalization of Einstein's master equation with a reactive term and we show how the mean field formulation leads to a generalized R-D equation with non-classical solutions. For the $n$-th order annihilation reaction $A+A+A+...+A\rightarrow 0$, we obtain a nonlinear reaction-diffusion equation for which we discuss scaling and non-scaling formulations. We find steady states with either solutions exhibiting long range power law behavior (for $n>\alpha$) showing the relative dominance of sub-diffusion over reaction effects in constrained systems, or conversely solutions (for $n<\alpha<n+1$) with finite support of the concentration distribution describing situations where diffusion is slow and extinction is fast. Theoretical results are compared with experimental data for morphogen gradient formation.Comment: Article, 10 pages, 5 figure

The Valuation of the Alberta Oil Sands

The Alberta oil sands reserves represent a very valuable energy resource for Canadians. In 2007, Statistics Canada valued the oil sands at $342.1 billion, or 5 per cent Canada's total tangible wealth of$6.9 trillion. Given the oil sands' importance, it is essential to value them appropriately. In this report, we critically review the methods used by Statistics Canada in their valuation of the Alberta oil sands. We find that the official Statistics Canada estimates of the reserves (22.0 billion barrels) of Alberta's oil sands are very small compared to those obtained using more appropriate definitions, which results in an underestimation of the true value of the oil sands. Moreover, the failure to take into account the projected growth of the industry significantly magnifies this underestimation. We provide new estimates of the present value of oil sands reserves based on a set of alternative assumptions that are, we argue, more appropriate than those used by Statistics Canada. We find that the use of more reasonable measures of the total oil sands reserves (172.7 billion barrels), extraction rate (a linear increase from 482 million barrels per year in 2007 to 1,350 million barrels in 2015, and constant thereafter) and price ($70 per barrel, 2007 CAD) increases the estimated present value of the oil sands to$1,482.7 billion (2007 CAD), 4.3 times larger than the official estimate of $342.1 billion. Using our preferred estimate, Canada’s total tangible wealth increases by$1.1 trillion (17 per cent), and reaches $8.0 trillion with oil sands now accounting for 18 per cent of Canada’s tangible wealth. The importance of these revisions is also demonstrated by their impact on the per-capita wealth of Canadians, which increases from$209,359 to $243,950, or by$34,591 (or 17 per cent). Given the importance of the oil sands for Canada, Statistics Canada should undertake a review of its methodology. In light of the growing body of climatologic literature supporting an association between anthropogenic GHG emissions and global climate change, no analysis of the „true value? of the oil sands would be complete without an accounting of the social costs of the GHG emissions that arise from oil sands development. According to our baseline estimates, the oil sands impose a total social cost related to GHG emissions of $69.4 billion. In making this estimate, we assume that each barrel of oil sands output imposes a social cost of$2.25 (based on a cost of $30/tCO2-e and an intensity of 0.075 tCO2-e/bbl). Our preferred estimate of the net present value of oil sands wealth net of GHG cost is thus$1,413.3 billion, 4.1 times greater than the Statistics Canada estimate which does not account for any environmental costs. This report does not account for non-GHG related environmental and social costs. A comprehensive valuation of all environmental costs are needed to assess whether future benefits derived from oil sands development are outweighed by even larger environmental costs.Cost-Benefit, Oil Sands, Environmental Damage, CO2 Emissions, Alberta, Energy, Natural Resources, Valuation

Missionary Kingdoms of the South Pacific?: the involvement of missionaries from the London Missionary Society in law making at Tahiti, 1795-1847

This thesis examines the involvement of members of the London Missionary Society in drafting law codes in Tahiti. It seeks to establish the missionaries' reasons for participating in the process and the explanations they gave of their actions. The thesis also considers the way in which the LMS presented these events to the public.The role played by the Tahitian Mission in drafting the law code in 1819 assisted Pomare II in increasing his authority beyond traditional limitations. Pomare II, through the advice of the mission, appropriated Western institutions which strengthened his claim to be king. The missionary fostering of a Tahitian monarchy had its roots in earlier European descriptions of Polynesian 'monarchs' upon which cross-cultural relations had already been established.The early missionaries developed a special relationship with Pomare II, their patron and protector, which eventually led to his adoption of Christianity in 1812. The Tahitian mission did not dominate Pomare but it did have a significant influence in the creation and presentation ofTahiti as a Christian Kingdom.The willingness of the missionaries to help Pomare II transform himself into a Christian monarch can be traced to factors in the origins of the LMS. The genuinely ecumenical character of the LMS in its early years resulted in the presence of missionaries and directors whose acceptance of close relations between Church and State was not typical of the Congregationalists who later dominated the Society. The influence of the Anglican Rev. Thomas Haweis, architect of the South Sea Mission, was particularly important in the years before 1819.Far from being a contradiction of the LMS regulation forbidding the involvement of missionaries in politics, the advice given by the missionaries to Pomare II can be interpreted as a result of the constant admonitions to avoid radical politics and obey lawful authority. These instructions, intended to convey and ensure the respectability of the newly founded LMS, when read in the Tahitian context, implied a duty to support the Pomare dynasty.The drafting of a law code for Tahiti, and the spread of the practice to other islands, reflects the Society's evangelical theology of conversion and a belief that all people had the capacity to appropriate the benefits of Christian civilisation. The law codes were briefly celebrated as a proof of the transforming power ofthe Gospel and the abilities of Pacific Islanders. The reticence of the LMS about the Tahitian laws in later years can be attributed to changing racial attitudes and a colonial discourse which presented Pacific Islanders as incapable of self-government. This embarrassment about the laws should not, however, be read back into the period of their composition or the years before 1847

Continuation of homoclinic orbits in the suspension bridge equation: a computer-assisted proof

In this paper, we prove existence of symmetric homoclinic orbits for the suspension bridge equation $u""+\beta u" + e^u-1=0$ for all parameter values $\beta \in [0.5,1.9]$. For each $\beta$, a parameterization of the stable manifold is computed and the symmetric homoclinic orbits are obtained by solving a projected boundary value problem using Chebyshev series. The proof is computer-assisted and combines the uniform contraction theorem and the radii polynomial approach, which provides an efficient means of determining a set, centered at a numerical approximation of a solution, on which a Newton-like operator is a contraction.Comment: 37 pages, 6 figure

The Effects of the COVID-19 Pandemic on Anxiety, Stress, and Resilience in Economically Challenged Single Mothers

The purpose of this qualitative phenomenological study was to describe the experiences of economically challenged single mothers during Covid 19. Mitigating the severe anxiety and stress risks linked with COVID-19 has been a goal of public health incentives. Less effort has been spent on studying the psychological issues connected to the worldwide epidemic, particularly among economically challenged communities. The aims of the study were to explore the impact of anxiety and stress of the COVID 19 pandemic on economically challenged single mothers, to determine the needs of this group, and to identify prevention and interventions that might support them in the event of another pandemic or traumatic event. The study was conducted with a transcendental phenomenological design in which nine single mothers were interviewed. An Interpretative Phenomenological Analysis (IPA) technique was used to analyze the data. Eight themes emerged from data analysis: (a) anxiety related to COVID-19, (b) stress related to COVID-19, (c) coping with stress and anxiety, (d) impact on finances, (e) impact on mental health, (f) influence of pandemic on relationships, (h) influence of the pandemic on responsibilities, and (g) resiliency, which described how participants moved forward, despite adversity. Participants experienced increased responsibilities, radical shifts to their work-home life, reduction of income, and feelings of social isolation, anxiety, and stress. In response to their many challenges, the participants were self-reliant, took the time to evaluate their lives, focused on self, were adaptable, and willing to pioneer changes in career and home life

Predicting Dust Distribution in Protoplanetary Discs

We present the results of three-dimensional numerical simulations that include the effects of hydrodynamical forces and gas drag upon an evolving dusty gas disk. We briefly describe a new parallel, two phase numerical code based upon the smoothed particle hydrodynamics (SPH) technique in which the gas and dust phases are represented by two distinct types of particles. We use the code to follow the dynamical evolution of a population of grains in a gaseous protoplanetary disk in order to understand the distribution of grains of different sizes within the disk. Our ``grains'' range from metre to submillimetre in size.Comment: 2 pages, LaTeX with 1 ps figure embedded, using newpasp.sty (supplied).
