Hand arthritis in systemic lupus erythematosus: an ultrasound pictorial essay.

A small minority of systemic lupus erythematosus (SLE) patients may develop a deforming arthritis, typically with a non-erosive (Jaccoud's) pattern, although erosive features indistinguishable from rheumatoid arthritis may also occur. High-resolution ultrasonography (HRUS) allows detailed 'real time' imaging of joint and tendon morphostructural changes involving the hand in patients with several rheumatic diseases. The main aim of this pictorial essay is to provide the first descriptive HRUS and power Doppler (PD) findings of joint and tendon involvement of the hand and wrist in patients with SLE arthritis. Seventeen patients with SLE and hand involvement were examined. HRUS of the wrist, 2nd and 3rd MCP joints, 3rd PIP joint and 2nd, 3rd and 4th finger flexor tendons were studied in the dominant hand for each patient. Sixteen (94%) patients had joint effusion or synovial hypertrophy in the wrist. Twelve (71%) patients had joint effusion or synovial hypertrophy in 2nd or 3rd MCPJs. Eight (47%) patients had erosion at 2nd or 3rd MCPJs. In three cases erosions were not present radiologically. Eleven (65%) patients had evidence of tenosynovitis. In SLE, HRUS with PD detects a high prevalence of inflammatory pathology in the tendons and synovium of the hand and wrist, and a high prevalence of MCP joint erosions. HRUS offers a sensitive, real-time and readily repeatable assessment of soft-tissue, inflammatory and bony changes in SLE hands.

Teenagers Telling Sectarian Stories

The purpose of this article is to examine the socially constructed nature of the story telling process by drawing on an example from one locality in Northern Ireland. The research draws on focus group interviews with teenagers from polarized working-class communities in North Belfast. The overall locality is divided into Catholic and Protestant areas and a recurring feature of the data is the tendency for each group to define themselves in opposition to the other. Throughout the focus group interviews, the teenagers produced four types of stories and the article assesses the relevance of each type to producing, reproducing or challenging sectarian divisions. The first three groups of stories, First-hand stories, Second-hand stories and Collective stories reflect individual and group attitudes to distinctions between ‘us’ and ‘them’ while the fourth, Alternative stories, questions the homogeneity of the in-group and the immutability of these divisions. These stories verbalize the internal recollections of both individuals and groups and rely on real and imagined memories. The thrust of the article illustrates the ways in which sectarian identities are constructed, shaped and diluted through these narrative encounters.

Organs of the human brain, created by the human hand? The social epistemology of information technology

Purpose
– Information science has been conceptualized as a partly unreflexive response to developments in information and computer technology, and, most powerfully, as part of the gestalt of the computer. The computer was viewed as an historical accident in the original formulation of the gestalt. An alternative, and timely, approach to understanding, and then dissolving, the gestalt would be to address the motivating technology directly, fully recognizing it as a radical human construction. This paper aims to address the issues.

Design/methodology/approach
– The paper adopts a social epistemological perspective and is concerned with collective, rather than primarily individual, ways of knowing.

Findings
– Information technology tends to be received as objectively given, autonomously developing, and causing but not itself caused, by the language of discussions in information science. It has also been characterized as artificial, in the sense of unnatural, and sometimes as threatening. Attitudes to technology are implied, rather than explicit, and can appear weak when articulated, corresponding to collective repression.

Research limitations/implications
– Receiving technology as objectively given has an analogy with the Platonist view of mathematical propositions as discovered, in its exclusion of human activity, opening up the possibility of a comparable critique which insists on human agency.

Originality/value
– Apprehensions of information technology have been raised to consciousness, exposing their limitations.

Post-release GPS tracking of hand-reared Irish hare Lepus timidus hibernicus leverets, Slemish, Co. Antrim, Northern Ireland.

Animal rescue centres release large numbers of captive-bred, rehabilitated or translocated animals into the wild annually but little is known about their post-release survival and behaviour. We developed a novel and innovative coupling of traditional radio-tags with new GPS loggers to track hand-reared Irish hare Lepus timidus hibernicus leverets after release into the wild. Cyanoacrylate SuperGlue® proved a poor fixative with two out of three leverets managing to detach their tags within 24 hours. Nevertheless, a total of 2,505 GPS locations were recorded every 60 seconds for one leveret over three nights (approx. 835 per night). The leveret dispersed

The Israeli-Palestinian Conflict: A People's War

The conflict between Israelis and Palestinians is one of the most enduring and complex in the modern world. But, why did the conflict break out? Who is demanding what, and why is peace so difficult to achieve?

The Israeli-Palestinian Conflict tackles the subject and analyses the conflict from its historical roots in the late nineteenth century to the present attempts at conflict resolution in the twenty-first century.

Framing the debate and analysis around issues such as Zionism, Palestinian nationalism, international peace efforts, the refugees, state-building, democracy and religious opposition and highlighted by first hand quotes and sources of the conflict from its major participants, Beverley Milton-Edwards explores the deep impact of the conflict on regional politics in the Middle East and why the enmity between Palestinians and Israelis has become a number one global issue drawing in the world’s most important global actors.

An essential insight into the complexities of one of the world’s most enduring conflicts between Israelis and Palestinians, this textbook is designed to make a complex subject accessible to all. Key features include a chronology of events and annotated further reading at the end of each chapter.

The Israeli-Palestinian Conflict is an ideal and authoritative introduction into aspects of politics in Israel, among the Palestinians – a vitally important issue for those studying the politics of the Middle East.

The Hand of Government in Shaping Accounting and Reporting in the UK Charity Sector

Accounting in the UK charity sector has changed massively over the last 25 years, with various stakeholders influencing what has occurred. Using insights from stakeholder theory, and interviews with a number of key actors, this article focuses on the influence of one definitive stakeholder – government – in developing a regime of quality accounting and reporting in the sector. In particular, the evolution of the Statement of Recommended Practice for charities is explored. It is argued that a much tighter and more meaningful regime of accounting and reporting has been encouraged by government, amongst other stakeholders, and this has led to a more accountable and healthier charitable sector.

Nonlinear Dynamics of Rotating Multi-Component Pair Plasmas and e-p-i Plasmas

The propagation of small amplitude stationary profile nonlinear electrostatic excitations in a pair plasma is investigated, mainly drawing inspiration from experiments on fullerene pair-ion plasmas. Two distinct pair ion species are considered of opposite polarity and same mass, in addition to a massive charged background species, which is assumed to be stationary, given the frequency scale of interest. In the pair-ion context, the third species is thought of as a background defect (e.g. charged dust) component. On the other hand, the model also applies formally to electron-positron-ion (e-p-i) plasmas, if one neglects electron-positron annihilation. A two-fluid plasma model is employed, incorporating both Lorentz and Coriolis forces, thus taking into account the interplay between the gyroscopic (Larmor) frequency ?c and the (intrinsic) plasma rotation frequency O0. By employing a multi-dimensional reductive perturbation technique, a Zakharov-Kuznetsov (ZK) type equation is derived for the evolution of the electric potential perturbation. Assuming an arbitrary direction of propagation, with respect to the magnetic field, we derive the exact form of nonlinear solutions, and study their characteristics. A parametric analysis is carried out, as regards the effect of the dusty plasma composition (background number density), species temperature(s) and the relative strength of rotation to Larmor frequencies. It is shown that the Larmor and mechanical rotation affect the pulse dynamics via a parallel-to-transverse mode coupling diffusion term, which in fact diverges at ?c ? ±2O0. Pulses collapse at this limit, as nonlinearity fails to balance dispersion. The analysis is complemented by investigating critical plasma compositions, in fact near-symmetric (T- ˜ T+) “pure” (n- ˜ n+) pair plasmas, i.e. when the concentration of the 3rd background species is negligible, case in which the (quadratic) nonlinearity vanishes, so one needs to resort to higher order nonlinear theory. A modified ZK equation is derived and analyzed. Our results are of relevance in pair-ion (fullerene) experiments and also potentially in astrophysical environments, e.g. in pulsars.
