Legal and professional implications of shared care: a case study in oral anticoagulation stroke prevention therapy.
Policy initiatives and technological advances enable the use of integrated shared care models of healthcare delivery whereby the focus of care is moved from the hospital to the community, and also of models where patients take increasing responsibility for monitoring and treatment. Such shifts may or may be perceived to change professional roles and responsibilities with implications to the delivery of a professionally and legally acceptable standard of care. We focus on oral anticoagulation and stroke prevention therapy to examine some possible professional and legal implications of the increasing use of shared care

Learning together: Lessons from a collaborative curriculum design project
Based on an action research project implemented at two South African universities, we argue that content and language integration (ICL) collaborative partnerships benefit not only from collaboration between language and content specialists, but in addition, from collaboration between language specialists, general education specialists and content specialists from a variety of disciplines. However, as we illustrate below, these benefits may be accompanied by substantial challenges. We make a further claim, for the value of a transformative approach towards collaboration for content and language integration, in which the teacher/researchers engage in their practice in a critical and reflexive manner, and by so doing, foster their own deep learning, as well as the deep learning of the students
Diffusion-controlled generation of a proton-motive force across a biomembrane
Respiration in bacteria involves a sequence of energetically-coupled electron
and proton transfers creating an electrochemical gradient of protons (a
proton-motive force) across the inner bacterial membrane. With a simple kinetic
model we analyze a redox loop mechanism of proton-motive force generation
mediated by a molecular shuttle diffusing inside the membrane. This model,
which includes six electron-binding and two proton-binding sites, reflects the
main features of nitrate respiration in E. coli bacteria. We describe the time
evolution of the proton translocation process. We find that the electron-proton
electrostatic coupling on the shuttle plays a significant role in the process
of energy conversion between electron and proton components. We determine the
conditions where the redox loop mechanism is able to translocate protons
against the transmembrane voltage gradient above 200 mV with a thermodynamic
efficiency of about 37%, in the physiologically important range of temperatures
from 250 to 350 K.Comment: 26 pages, 4 figures. A similar model is used in arXiv:0806.3233 for a
different biological system. Minor changes in the Acknowledgements sectio
The diary of Robert John Mullins (1833-1913)
Summary of Content: This volume offers its readers extracts from the diary and the correspondence of Robert John Mullins, Anglican missionary, priest and in due time principal of what was called the Kafir Institution in Grahamstown and as such a pioneer in the field of western education to black South Africans. After his marriage to Jennie Roe he was assisted in all that he undertook by a loyal and devoted wife. The editors have made use of the earlier diaries and manuscripts because of the light they shed on the conditions in the eastern Cape frontier in the crucial years before and after the cattle-killing. While Mullins' own observations are those of a young missionary his remarks and the record of his experiences are themselves to be viewed in the light of the recent scholarship in regard to the cattle-killing which reveals the multisidedness of an appalling social tragedy. What Mullins wrote records, for better or for worse, episodes which show how South Africans of different origins have in the past regarded one another. Mullins was a committed Christian eager to offer to all whom he could reach the salvation of Christ in which he so fervently believed.He was often intolerant of Xhosa customs he could not understand as well as often perplexed and discouraged. But the overwhelming impact of this record is what it took to be a missionary: courage, commitment, humour, resilience, a capacity to endure physical hardship and enjoy physical activity. All these were qualities which Robert John Mullins possessed in abundance. As his diary shows they were the qualities the frontier demanded. Working over a long period of time Nancy Charton and Brenda Nicholls (who became a coeditor in 1991) have transcribed the diary entries and the correspondence working with the help of the sites of some of the missionary activity. The help of members of the Mullins family (notably Judy Sturrock and her husband) is gratefully acknowledged. Earlier generous contributions made it possible to obtain a typescript from which the editors could work. Every effort has been made to identify the individuals (Xhosa, Tembu and white) and events (both in South Africa and abroad) which are alluded to in the diary. This was a time consuming task and the editors are grateful to all who helped them with it. The book consists of an introduction and eleven chapters. The introduction describes the material and the methods of the editors, discusses the religious and social conditions of the time, addresses the problems of interpartition presented by the cattle-killings, turns attention to the dilemmas of missionaries and then focusses the attention of readers on the diarist Robert John Mullins (with Jennie as later stand-in) as well as the value of the diary. There is much to interest the educationist, the theologian, the economist, and the historian. Chapter 1 deals with Mullins' voyage to the Cape in 1854 and the extracts record the experiences of an exuberant as well as a dedicated lad of sixteen. Chapter 2 deals with the arrival at the Cape in 1854. Chapter 3 gives us a picture of Mullins' experience of Graham's Town in 1854. Chapter 4 deals with Mullins' experience at St Luke's Mission. Chapter 5 covers the period of 1856-57 when Mullins was at Balotwa and the cattle-killing frenzy developed. Chapter 6 describes the hunger and turmoil which followed in the wake of the cattle-killing. Chapter 7 describes the founding of a new station, St Peter's Gwytyu. Chapter 8 is concerned with life at St Peter's in the early months of 1858. Chapter 9 covers the last months at St Peter's and his journey to the Bashee. Chapters 10 and 11 cover the early years in the married life of Robert John Mullins and his wife Jennie. The Mullins' delight in family life is strongly evident in their joy in each other's company and their anxious joy over their first-born baby. Chapter 11 gives the reader the texts of letters written by Robert John and his wife Jennie in the years which marked the end of Mullins' career as a frontier missionary, and the opening to him of the opportunity to become Principal of the Kafir Institution. A map carefully prepared by Mr Oakley West of the Geography Department, with the assistance of Deby Brody, enables the reader to trace the frontier journeys of Robert John Mullins and his wife Jennie who were among the pioneers of frontier societies who did their best to make available to others what they believed to be the eternal benefits of the Christian faith, and the accompanying mores of the 'western' culture of their day
