Lacerda’s chromographs (1930s-1950s): the circulation and appropriation of knowledge in Europe and the Americas

From the 1930s to the early 1950s, chromography, a technique invented and developed by Armando de Lacerda, constituted an advanced method of investigation in the field of Phonetics which overcame the limitations of kymography, the method predominantly used in Experimental Phonetics laboratories during the period. The new technique was first used by Lacerda in collaboration with Paul Menzerath in Bonn, its use later spreading to Portugal and Brazil. The existence of the most advanced chromographic equipment at the University of Coimbra Experimental Phonetics Laboratory since 1936 explains why Portugal became a global centre for Phonetics research and remained such up until the 1950s, attracting numerous scientists from abroad who, under the supervision of its head, Armando de Lacerda, received specialist training in the use of chromography. Later, the technique was used at the University of Bahia, where Lacerda and Nelson Rossi established the first Experimental Phonetics laboratory in South America in 1956-57, and where the first work on linguistic geography of Brazil, entitled Atlas Prévio dos Falares Baianos, was produced.IHC - Pólo da UE.

Interview with Dr. Roger Ray: Rollins Alumnus and Professor of Psychology

Roger Dean Ray came to Rollins College in 1969 to teach psychology. Over his tenure, he has authored numerous publications and engaged in many experimental projects. Eventually, Ray became the head of the Department of Psychology and the founding director of the Quantitative Learning and Teaching Center at Rollins. Born in New Castle, Indiana, in 1941, Ray earned his B.A. in mathematics and psychology from Rollins College. He then studied at the University of Wisconsin for two years before completing his Ph.D. in general experimental psychology at the University of Tennessee in 1969. While at Rollins College, Ray engaged in many collaborative efforts. Co-authoring, researching with students, and working with international scientists all reflect Ray\u27s understanding of his field\u27s cumulative nature. During the late \u2780s and early \u2790s he worked alongside Soviet scientists at Rollins on a project that analyzed how mechanisms in brains deal with new information. In 1996, he developed Cyber Rat, an online program that simulates rat behavior for lab use by psychology students. Among other distinctions he received the 1980 President\u27s Award for Best of Conference paper at the International Congress on Applied Systems and Cybernetics, the McKean Award in 1986, the Erlbaum/ SCiP Distinguished Presentation Academic Excellence Award in 1991, and the Bornstein Award for Faculty Scholarship in 2007. Ray\u27s academic interests include observational methodology, behavioral systems analysis, and adaptive instructional design. He published many research articles, including Interbehavioral Methodology: Lessons from Simulation, Using virtual reality to deliver laboratory experiences in undergraduate education, and Setting changes and the quality of human life. Besides his academic career, Ray also enjoys sculpture and interior design, in addition to participating in several sports--most notably, water skiing. Once a professional in the sport, Ray won numerous championships while he was a student and was inducted into the Rollins College Alumni Sports Hall of Fame in 1991

COVLIAS 1.0Lesion vs. MedSeg : An Artificial Intelligence Framework for Automated Lesion Segmentation in COVID-19 Lung Computed Tomography Scans

COVID-19 is a disease with multiple variants, and is quickly spreading throughout the world. It is crucial to identify patients who are suspected of having COVID-19 early, because the vaccine is not readily available in certain parts of the world.Lung computed tomography (CT) imaging can be used to diagnose COVID-19 as an alternative to the RT-PCR test in some cases. The occurrence of ground-glass opacities in the lung region is a characteristic of COVID-19 in chest CT scans, and these are daunting to locate and segment manually. The proposed study consists of a combination of solo deep learning (DL) and hybrid DL (HDL) models to tackle the lesion location and segmentation more quickly. One DL and four HDL models-namely, PSPNet, VGG-SegNet, ResNet-SegNet, VGG-UNet, and ResNet-UNet-were trained by an expert radiologist. The training scheme adopted a fivefold cross-validation strategy on a cohort of 3000 images selected from a set of 40 COVID-19-positive individuals.The proposed variability study uses tracings from two trained radiologists as part of the validation. Five artificial intelligence (AI) models were benchmarked against MedSeg. The best AI model, ResNet-UNet, was superior to MedSeg by 9% and 15% for Dice and Jaccard, respectively, when compared against MD 1, and by 4% and 8%, respectively, when compared against MD 2. Statistical tests-namely, the Mann-Whitney test, paired t-test, and Wilcoxon test-demonstrated its stability and reliability, with p < 0.0001. The online system for each slice was <1 s.The AI models reliably located and segmented COVID-19 lesions in CT scans. The COVLIAS 1.0Lesion lesion locator passed the intervariability test

Introduction by Professor Tom Meade, London School of Hygiene and Tropical Medicine.Annotated and edited transcript of a Witness Seminar held on 25 November 2003. Introduction by Professor Tom Meade, London School of Hygiene and Tropical Medicine.The recent history of research on platelets and its applications in medicine started with the introduction of ex vivo methods for studying platelet behaviour. The Witness Seminar held on 25 November 2003, chaired by Professor Tom Meade, considered the detailed study of platelets starting with the recognition of their role in haemostasis, both in thrombotic and bleeding disorders . Professor Gustav Born described his research and the invention and development of the optical aggregometer that bears his name. Other topics included the biochemistry and function of platelets ; the platelet release reaction and the effect of aspirin on it ; the Nobel Prize-winning discovery by Sir John Vane of how aspirin inhibits the natural production of prostaglandins; and results of randomized controlled trials of aspirin and other thrombolytic drugs for the prevention of thrombotic conditions. An appendix includes a discussion of the streptokinase trials, 1986-96, from the unpublished Witness Seminar meeting on Thrombolysis held on 28 January 2003, chaired by Professor Brian Pentecost. Participants : Dr Y S [Mick] Bakhle, Sir Christopher Booth, Professor Donald Chambers, Professor John Dickinson, Professor Peter Elwood, Professor Rod Flower, Professor Alison Goodall, Professor John Hampton, Professor Michael Harrison, Professor Stan Heptinstall, Dr Peter Hunter, Dr Peter MacCallum, Dr Marty Mahaut-Smith, Professor Salvador Moncada, Professor Michael Oliver, Professor Clive Page, Professor Sir Stanley Peart, Professor Colin Prentice, Professor Peter Richardson, Dr Stewart Sage, and Dr Duncan Thomas; and from Thrombolysis, Dr Hewan Dewar, the late Sir Richard Doll, Professor John Hampton, Dr Arthur Hollman, Professor Desmond Julian, Dr Robin Norris, Professor Tom Quinn, Dr Roger Smith, and Professor Andrew Stevens.

Networks as ‘laboratories of experience’: exploring the life cycle of the suffrage movement and its aftermath in Ireland 1870–1937

Applying an innovative conceptual framework this article presents an interdisciplinary re-appraisal of the suffrage movement and its aftermath in Ireland throughout the years 1870–1937. New social movement theory is utilised to consider how, in the words of the Italian sociologist Alberto Melucci ‘the submerged networks of social movements are laboratories of experience’. Going beyond the previously published work of each author, this article uses the sociological lens of ‘laboratories of experience’ to re-analyse aspects of the suffrage movement, female activism and the wider women's movement in Ireland. This application of social movement theory to female networks, their origins, aims and strategies, along with their interconnectedness, provides a more nuanced and detailed understanding of the ‘life-cycle’ of this movement. The article aims to demonstrate how an analysis of network dynamics and application of the concept of ‘latency’ is useful in further understanding the significance, impact and longevity of the women's movement in Ireland
