Using nitrogen stable isotope ratios (delta N-15) of macroalgae to determine the effectiveness of sewage upgrades: changes in the extent of sewage plumes over four years in Moreton Bay, Australia

Nitrogen loading to aquatic ecosystems from sewage is recognised worldwide as a growing problem. The use of nitrogen stable isotopes as a means of discerning sewage nitrogen in the environment has been used annually by the Ecosystem Health Monitoring Program in Moreton Bay (Australia) since 1997 when the technique was first developed. This (sewage plume mapping) technique, which measures the delta(15)N isotopic signature of the red macroalga Catenella nipae after incubation in situ, has demonstrated a large reduction in the magnitude and spatial extent of sewage nitrogen within Moreton Bay over the past 5 years. This observed reduction coincides with considerable upgrades to the nitrogen removal efficacy at several sewage treatment plants within the region. This paper describes the observed changes and evaluates whether they can be attributed to the treatment upgrades. (c) 2004 Published by Elsevier Ltd.

Responding to our customers' needs: modifications to assessment in Obstetrics and Gynaecology over 20 years

Background and Objectives: This paper reports on historical changes in assessment culminating in the experience of one discipline with negotiated student feedback that has helped design and modify assessment to cater for the requirements of both students and teachers. The standard of assessment required to pass Obstetrics and Gynaecology in the four year graduate entry program in the School of Medicine at The University of Queensland, Brisbane, Australia has become less formalised and more collaborative. Changes in assessment in this discipline over the last 20 years reflect the development of an understanding of the educational principles associated with adult teaching and learning. Assessment has evolved from being teacher focussed, with questionable reliability, validity, and emphasis on outcomes, to being focussed on learning and the student. Multiplechoice examinations, combined with a collaborative approach to the reliability and validity of questions and answers and a debrief or feedback session have been found to provide an assessment format that is art acceptable measure oflearning for both teachers and students. Changes in assessment reflect a collaborative process between teachers and students based on principles of adult learning and involving negotiated student feedback. Our experience with this form of negotiated outcome for assessment is presented together with suggestions for improvement and is contrasted with assessment methods used in this department over the last 20 years. Change and refinement will continue as medical programs strive to meet the learning needs of students and assessment outcomes that are acceptable to its teachers.

Choroidal osteoma: evidence of progression and decalcification over 20 years

Choroidal osteoma is a rare, benign, ossifying tumour of the choroid of unknown aetiology. In contrast to other types of intraocular ossification, choroidal osteoma is found typically in young healthy females in the second or third decades of life with no history of systemic or ocular disease. Choroidal osteoma is a deep, pale yellow lesion with distinct geographic borders at the juxtapapillary or macular region, with branching 'spider' vessels on the surface of the tumour. These features should help differentiate choroidal osteoma from other types of intraocular tumour and the diagnosis can be confirmed with ultrasonography and computerised tomography. Here we report an initially unilateral case of choroidal osteoma, which decalcified over 20 years but during the same period the fellow eye also developed a choroidal osteoma to become a bilateral case. Despite the benign nature of the tumour, vision may be compromised by gradual atrophy of the overlying retina, serous retinal detachment, accumulation of sub-retinal fluid and sub-retinal haemorrhage associated with choroidal neovascularisation. Frequent examinations are recommended for patients with choroidal osteoma, for early detection of a subretinal neovascular membrane and potential treatment with laser photocoagulation.

Radial growth of Rhizocarpon section Rhizocarpon lichen thalli over six years at snoqualmie pass in the Cascade Range, Washington State

This article describes a 6-yr study of the radial growth rates (RGR, mm yr-1) of Rhizocarpon section Rhizocarpon thalli on a talus slope at Snoqualmie Pass in the Cascade Range, Washington State, United States (47°27'N; 121°26'W). At the end of the growth period, 32 of a total of 39 thalli had exhibited a positive RGR, and 7 of a total of 39 thalli showed no measurable growth. Mean RGR of all thalli was 0.07 mm yr-1 (range, 0-0.19 mm, SD = 0.06). Analysis of variance suggested no significant variation in RGR in successive growth periods, but significant differences were present both within and between thalli. The slope of a boulder facet did not influence RGR, but growth was affected by aspect, the least growth being observed on north-northwest facets. A plot of RGR against thallus diameter revealed a wide scatter of data points with little evidence for a significant change in growth with thallus size. Hence, the study showed that the RGR of Rhizocarpon thalli at Snoqualmie is extremely slow and highly variable and significantly less than estimates based on lichenometry. To determine the growth curve of a yellow-green Rhizocarpon by direct measurement at such a site would require a large sample of thalli and careful standardization of the species studied, the aspect conditions under which the thalli were measured, and the initial hypothallus width of the thalli. © 2005 Regents of the University of Colorado.

An enigma still: Poujadism fifty years on

Few names resonate more loudly from the French Fourth Republic than that of Pierre Poujade, and few terms exude such a sulfurous odour as le poujadisme. Between 1953 and 1958, the Poujadists secured their place in modern French history, winning 52 seats in the National Assembly and inscribing a lasting entry in the lexicon of political protest. Taking as its starting point the fiftieth anniversary of Poujade’s movement held in its birthplace of Saint-Céré in July 2003, this article reassesses Poujadism fifty years on from its heyday. It considers Poujadism as the first important anti-globalisation movement in post-war France, a locus for the conflict between ‘stalemate’ traditionalism and socio-economic modernisation. It examines the trajectory of the Poujadists from anti-tax movement to political party, arguing the difficulty of defining Poujadism in classic political terms. In particular, the article takes issue with the perception of Poujadism as an extreme-right ideology and interprets it instead as a form of populist protest lacking a solid doctrinal core and opportunistic in its exploitation of political issues and allies. As such, it is argued, Poujadism represents a complex synthesis of both right-wing and left-wing values and discourses, as impervious to definition today as it was fifty years ago. The article considers the brief alliance of convenience between Poujade and Le Pen, and locates in Le Pen’s early Poujadist experience some of the methods and even some of the arguments used by the FN today. It concludes by discussing Poujade’s political activities after 1958, tracing his long-term conversion from violent opposition to the State under the Fourth Republic to co-operation under the Fifth. The author draws here on correspondence with Pierre Poujade up until his death in August 2003.
