Haas-Molnar Continued Fractions and Metric Diophantine Approximation.
No full textHaas–Molnar maps are a family of maps of the unit interval introduced by A. Haas and D. Molnar. They include the regular continued fraction map and A. Renyi’s backward continued fraction map as important special cases. As shown by Haas and Molnar, it is possible to extend the theory of metric diophantine approximation, already well developed for the Gauss continued fraction map, to the class of Haas–Molnar maps. In particular, for a real number x, if (p n /q n )n≥1 denotes its sequence of regular continued fraction convergents, set θ n (x) = q 2n|x − p n /q n |, n = 1, 2.... The metric behaviour of the Cesàro averages of the sequence (θ n (x))n≥1 has been studied by a number of authors. Haas and Molnar have extended this study to the analogues of the sequence (θ n (x))n≥1 for the Haas–Molnar family of continued fraction expansions. In this paper we extend the study of n≥1 for certain sequences (k n )n≥1, initiated by the second named author, to Haas–Molnar maps

20 Years of Archive Fever (Freud Museum)
No full text"It is what is happening, right here, when a house, the Freuds' last house, becomes a museum: the passage from one institution to another." (Jacques Derrida, 'Archive Fever')
Presented as a gift to the Freud Museum, Jacques Derrida's 1994 lecture 'Archive Fever' remains a compelling work for scholars and artists interested in the relationship between archives, memory, and technology.
Originally titled 'The Concept of the Archive: A Freudian Impression', Derrida's deconstruction of the act of archiving beautifully opens up the contradictory nature of archives: how they are simultaneously public and private spaces, institutive and conservative, traditional and revolutionary. To mark the 20th anniversary of the lecture, the 'archive' at the centre of Derrida's thinking - the Freud Museum - invited a number of academics who attended the lecture to recall their memories of it, offer their interpretations of the work, and explore its continued relevance today.
The panel included Riccardo Steiner (Psychoanalyst and speaker at the original conference), Prof. Sarah Wilson (Courtauld Institute, where the conference was held), Prof. Dany Nobus (Brunel University), Dr. Forbes Morlock (Syracuse University), Julia Borossa (Middlesex University) and Michael Molnar (Former Director of the Freud Museum and principal conference organizer).
"Derrida sees in Freud's writing the very desire that is Archive Fever: the desire to recover moments of inception: to find and possess all sorts of beginnings." (Carolyn Steedman, 'Dust')
In addition to the panel discussion, experts from different academic disciplines explained the importance of 'Archive Fever' to their work.
Contributions included talks by Prof. Carolyn Steedman (Emeritus Professor of History at Warwick University, and author of Dust: The Archive and Cultural History), Dr. Beverley Butler (Senior Lecturer at UCL's Institute of Archaeology), and Professor Jérôme Lèbre (Paris)
The event was curated by Guy Atkins (Doctoral Researcher at Goldsmiths and the Museum of London) and was recorded by James Bulley (Doctoral Researcher at Goldsmiths, University of London).

Brass Art: A house within a house within a house within a house
No full textPerformances from Brass Art (Lewis, Mojsiewicz, Pettican), captured at the Freud Museum, London, using Kinect laser scanning and Processing, reveal an intimate response to spaces and technologies. ‘A house within a house within a house within a house’ links historical and cultural representations of the double, the unconscious and the uncanny to this artistic practice. The new moving-image and sonic works form part of a larger project to inhabit the writing rooms of influential authors, entitled ‘Shadow Worlds | Writers’ Rooms’
A note on exchange rate pass-through in CIS countries
No full textWe assess the extent and speed of exchange rate pass-through in the countries of the Commonwealth of Independent States (CIS). We do this in the framework of vector autoregressive regressions, utilising impulse functions and variance decompositions with monthly data that starts in 1999 in order to avoid periods of very high inflation and the Russian crisis. We find that exchange rate movements have a clear impact on price developments in the CIS countries. The speed of the pass-through is also fairly high: in most cases the full effect is transmitted into domestic prices in less than 12 months. Unlike in many other emerging market economies, an additional effect from US prices on to domestic prices is not significant. The extent of the exchange rate pass-through is usually much higher than in our benchmark group of emerging market countries. Variance decomposition shows that the relative share of exchange rates in explaining changes in domestic prices is higher in the CIS countries than in the benchmark group. Our results indicate that policy-makers in the CIS countries need to pay more attention to exchange rate movements than in many other emerging market countries.exchange rate pass-through; inflation; exchange rate regime; transition countries
Women and forestry : operational issues
No full textWomen are major actors in forestry throughout the developing world. Women and children are the primary collectors of fuel and fodder for home consumption and for sale to urban markets. This alone gives women a major role in the management and conservation of renewable forest resources. When convinced of the utility and practicality of a forest improvement or management scheme, women can be a powerful lobby to persuade their entire houshold or community to invest the resources necessary to make the scheme work. Involving women in forestry projects often makes the difference between achieving or not achieving project objectives, particularly for the long-term sustainability of interventions.Environmental Economics&Policies,Forests and Forestry,Forestry,Agricultural Knowledge&Information Systems,Health Monitoring&Evaluation
Safety and efficacy of erythropoietin for the treatment of patients with optic neuritis (TONE): a randomised, double-blind, multicentre, placebo-controlled study.
No full textBACKGROUND
The human cytokine erythropoietin conveys neuroprotection in animal models but has shown ambiguous results in phase 2 clinical trials in patients with optic neuritis. We assessed the safety and efficacy of erythropoietin in patients with optic neuritis as a clinically isolated syndrome in a multicentre, prospective, randomised clinical trial.
METHODS
This randomised, placebo-controlled, double-blind phase 3 trial, conducted at 12 tertiary referral centres in Germany, included participants aged 18-50 years, within 10 days of onset of unilateral optic neuritis, with visual acuity of 0·5 or less, and without a previous diagnosis of multiple sclerosis. Participants were randomly assigned (1:1) to receive either 33 000 IU erythropoietin or placebo intravenously for 3 days as an adjunct to high-dose intravenous methylprednisolone (1000 mg per day). Block randomisation was performed by the trial statistician using an SAS code that generated randomly varying block sizes, stratified by study site and distributed using sealed envelopes. All trial participants and all study staff were masked to treatment assignment, except the trial pharmacist. The first primary outcome was atrophy of the peripapillary retinal nerve fibre layer (pRNFL), measured by optic coherence tomography (OCT) as the difference in pRNFL thickness between the affected eye at week 26 and the unaffected eye at baseline. The second primary outcome was low contrast letter acuity at week 26, measured as the 2·5% Sloan chart score of the affected eye. Analysis was performed in the full analysis set of all randomised participants for whom treatment was started and at least one follow-up OCT measurement was available. Safety was analysed in all patients who received at least one dose of the trial medication. This trial is registered at ClinicalTrials.gov, NCT01962571.
FINDINGS
108 participants were enrolled between Nov 25, 2014, and Oct 9, 2017, of whom 55 were assigned to erythropoietin and 53 to placebo. Five patients were excluded from the primary analysis due to not receiving the allocated medication, withdrawn consent, revised diagnosis, or loss to follow-up, yielding a full analysis set of 52 patients in the erythropoietin group and 51 in the placebo group. Mean pRNFL atrophy was 15·93 μm (SD 14·91) in the erythropoietin group and 14·65 μm (15·60) in the placebo group (adjusted mean treatment difference 1·02 μm; 95% CI -5·51 to 7·55; p=0·76). Mean low contrast letter acuity scores were 49·60 (21·31) in the erythropoietin group and 49·06 (21·93) in the placebo group (adjusted mean treatment difference -4·03; -13·06 to 5·01). Adverse events occurred in 43 (81%) participants in the erythropoietin group and in 42 (81%) in the placebo group. The most common adverse event was headache, occuring in 15 (28%) patients in the erythropoietin group and 13 (25%) patients in the placebo group. Serious adverse events occurred in eight (15%) participants in the erythropoietin and in four (8%) in the placebo group. One patient (2%) in the erythropoietin group developed a venous sinus thrombosis, which was treated with anticoagulants and resolved without sequelae.
INTERPRETATION
Erythropoietin as an adjunct to corticosteroids conveyed neither functional nor structural neuroprotection in the visual pathways after optic neuritis. Future research could focus on modified erythropoietin administration, assess its efficacy independent of corticosteroids, and investigate whether it affects the conversion of optic neuritis to multiple sclerosis.
