Site-Specific Protest: Liberate Tate’s Performances At Tate Modern

This paper analyzes the site-specific performances of Liberate Tate, an artist collective that staged protests at Tate galleries to oppose the institution's sponsorship deal with the multinational corporation BP. Arguing that the aesthetic, spatial, political, social, and ecological components of Liberate Tate's works are intricately enmeshed, the paper offers a dose visual analysis of the performances in relation to one of their sites, Turbine Hall at Tate Modern. Doing so, the paper demonstrates how the artist collective reacted to the socio-political structuring of the physical space in their own political mode of aesthetics. The site-specific works of the group attend to and confront the museum space to such an extent that the intervened space becomes Liberate Tate's principal medium. Through their horizontal arrangement mode, choice of messy, dirty, and viscous materials, and approach to nature, culture, and history as inseparable concepts, Liberate Tate's site-specific performances challenge the hegemonic neoliberal rhetoric of Tate Modern. The contrasts and conflicts Liberate Tate introduces against the visual discourse of Turbine Hall not only reveals the dominant political, financial, and social order of the space but also transforms the museum albeit temporarily into a truly public space of democracy

Canyon Collective Artists: Micropolitics in West Coast Experimental Film, 1960-79

In 1961, filmmakers Bruce Baillie, Chick Strand, Larry Jordan, and film critic Ernest Callenbach founded Canyon Cinema for weekly film screenings of a diverse selection of avant-garde, experimental and art-house films, newsreels, cartoons and animations as well as commercial Hollywood movies. Canyon screenings took place on locations expanding from San Francisco into Oakland, San Jose, and Berkeley as many as three times a week. This gravitation toward mobility, variation and flexibility also showed itself in the prolific film production of the members of the collective. Through use of methods such as appropriation, fragmentation, and reflexivity, Canyon filmmakers developed more intimate (memory), immediate (experience), and imaginative (fantasy) ways of engaging with the past. At the same time, their search for historic and ethnographic realities constantly question the conventional methods, genres, and medium-specific elements of filmmaking. In my dissertation, I re-evaluate the ways in which Canyon filmmakers approached the ethical, political, and cultural issues inherent in the representation of culture and history through the help of three concepts: performance in Strand\u27s ethnographies and found footage films, allegory in Baillie\u27s newsreels, and indexicality in Jordan\u27s animations. In the first chapter, I focus on the evocation of issues of sexuality, minority politics, and history in Bruce Baillie\u27s films. Reflecting on Baillie\u27s approaches to representation of race, culture, and gender, I consider how and what type of minority movement allegories transpired in Baillie\u27s cinema. My second chapter concentrates on Chick Strand\u27s films in its entirety comprising both found footage and documentary works. I analyze Strand\u27s citational, reflexive, and performative uses of pleasure, desire, and humor as productive strategies of bridging the then-wide gap between experimental and feminist cinemas. Larry Jordan\u27s animations and live-action films, which explore the dynamic tensions between still and moving imagery, visual and tactile sensations, and surrealist, lyrical and ethnographic modes of filmic expression, constitute the focus of the third chapter. Considering the notions of repetition, transformation, layering, and materiality that dominates Jordan\u27s films, I question how his films resist linear narratives by revealing alternative paths, multiple voices, and cyclical repetitions of histories

A bound on the primes of bad reduction for CM curves of genus 3

We give bounds on the primes of geometric bad reduction for curves of genus three of primitive CM type in terms of the CM orders. In the case of elliptic curves, there are no primes of geometric bad reduction because CM elliptic curves are CM abelian varieties, which have potential good reduction everywhere. However, for genus at least two, the curve can have bad reduction at a prime although the Jacobian has good reduction. Goren and Lauter gave the first bound in the case of genus two. In the cases of hyperelliptic and Picard curves, our results imply bounds on primes appearing in the denominators of invariants and class polynomials, which are important for algorithmic construction of curves with given characteristic polynomials over finite fields

Teaching Architectural Design Studio Remotely: The Introduction to Architectural Design Course at METU

This paper aims to briefly assess the potentials and limits of online learning environment for studio education by focusing on the case of 2019-20 spring semester studio of Introduction to Architectural Design course at Middle East Technical University’s Department of Architecture. As a transitory course between basic design principles and architectural design, Introduction to Architectural Design addresses the issues of site, program, structure, form, and material in reference to small scale architectural interventions. Reviewing the usual course of the semester until the COVID-19 outbreak as well as the effects of the unexpected switch to the emergency distance teaching, the paper highlights both the creative advantages and material shortcomings of the course’s adaptation process into the online studio format

THE EFFECT OF COVID-19 OUTBREAK ON THE MENTAL STATUS OF HEALTH CARE PROFESSIONALS IN THE PEDIATRIC INTENSIVE CARE UNIT

Background: Coronavirus disease 2019 (COVID-19) may affect the mental status of health care professionals. The purpose of our study is to evaluate the mental health effects of the COVID-19 epidemic on health care professionals in the pediatric intensive care units (PICUs). Subjects and methods: Our study was conducted prospectively between 01.04.20 and 10.04.20. The created questionnaire was applied to health care professionals through online platforms. Thus it was involved in 5 different institutions that participated from different regions of Turkey. With the questionnaire, we applied; the participants\u27 age, gender, the general status of contamination and the level of COVID-19 knowledge were questioned. Besides; Beck Anxiety Scale, Acute Stress Scale (PCL-5), STAI-1 and STAI-2 (State and Trait Anxiety Inventory 1-2) scales were used to determine the anxiety levels. Results: A survey of 210 participants, 86 (41%) doctors, 124 (59%) nurses, were included in our study. When we evaluate the Beck anxiety levels, the majority of the participants (44%) were normal, while about one third had mild anxiety. When we evaluated the acute stress scale, all participants had a certain amount of stress levels. The majority (80 people each (38%)) experienced mild and moderate acute stress. Being female and having chronic disease poses a high risk for anxiety (OR, 0.330; 95% CI, 0.087-1.250, p <0.05 and OR, 0.246; 95% CI, 0.068-1.116, p<0.05), preoccupation (OR, 0.603; 95% CI 0.261-1.395, p<0.05 and OR, 0.433; 95% CI, 0.122-1.538, p<0.05) and acute stress (OR, 0.294; 95% CI, 0.033-2.649, p<0.05 and OR, 0.317; 95 % CI 0.060-1.679, p<0.05). Professional definition, marital status and having a child do not pose any risk factors. Conclusion: Our study has shown that the COVID-19 outbreak affects the mental status of health care professionals working at PICU at various levels

Evaluation of renal near-infrared spectroscopy for predicting extubation outcomes in the pediatric intensive care setting

BackgroundIn pediatric intensive care units, extubation failure following invasive mechanical ventilation poses significant health risks. Determining readiness for extubation in children can minimize associated morbidity and mortality. This study investigates the potential role of renal near-infrared spectroscopy (RrSO2) in predicting extubation failure in pediatric patients.MethodsA total of 84 patients aged between 1 month and 18 years, mechanically ventilated for at least 24 h, were included in this prospective study. RrSO2 levels were measured using near-infrared spectroscopy before and during an extubation readiness test (ERT). The primary outcome measure was extubation failure, defined as a need for reintubation within 48 h.ResultsOf the 84 patients, 71 (84.6%) were successfully extubated, while 13 (15.4%) failed extubation. RrSO2 was found to be lower in the failed extubation group, also decrease in RrSO2 values during ERT was significantly greater in patients with extubation failure. ROC analysis indicated a decrease in ΔRrSO2 of more than 6.15% from baseline as a significant predictor of extubation failure, with a sensitivity of 0.984 and a specificity of 0.889.ConclusionMonitoring changes in RrSO2 values may serve as a helpful tool to predict extubation failure in pediatric patients. Further multi-center research is warranted to improve the generalizability and reliability of these findings

Epidemiology of pemphigus in Turkey: One-year prospective study of 220 cases

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation).  The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.   </p

Yerellik, Yeni Maddeselcilik, ve Sinema: Türkiye’de Duyusal Etnografik Sinema Pratikleri

Bu bildiri minör bir sinemasal biçim olan ‘duyusal etnografik film’ kavramını Türkiye’deki belgesel sinema üretimi üzerinden ve yerellik ve evrensellik arasındaki gerilim temasını eksen alarak incelemektedir. Klasik ve geleneksel görsel etnografik pratiklerin sebep olduğu güç hiyerarşisine karşı çıkan bir yöntem olarak ortaya çıkan duyusal etnografik sinema, kuramını ortaya atan Lucien Castaing-Taylor’a göre, belirli biryer ve zaman bağlamına vurgu yaparak, bu bağlamdaki hem görüntülenen hem de görüntüleyen öznelerin bedensel ve duygusal (affective) deneyimlerini yansıtırken, bir taraftan da seyircide de benzer bir duyusal deneyim oluşturmayı amaçlar. Duyusal etnografik filmlerin en önemli özelliklerinden birisi, insanı merkezlerine oturtmayan ve sinemasal araçları da içine alan teknolojileri, yerel habitatı ve bu habitatı oluşturan nesne, bitki, hayvan ve insanları eşitlikçi bir çerçeveden ele alan yöntemleridir. Bu bakımdan duyusal etnografinin doğa ve kültür arasında oluşturulan yapay zıtlığa ve insanı eksen alan düşünce biçimlerine karşı çıkan yeni maddeselcilik felsefesine yakın durduğu söylenebilir. Kendilerini duyusal etnografik olarak tanımlamasalar da Türkiye’de üretilmiş Sırtlarındaki Hayat (Yeşim Ustaoğlu, 2004) ve Demsala Dawî Şewaxan (Son Mevsim Şavaklar, Kazım Öz, 2009) gibi bazı belgesel sinema örnekleri de yerel bir kültürün pratiklerini beden, duyu ve duygulara yaptıkları vurgu ile incelemeleri bakımından bu kategoriye yakınlık gösterirler. Bildiri bu iki belgeselin yerellik ve evrensellik kavramları arasındaki gerilimi ortaya koymaları açısından, özellikle de küreselleşme ve neoliberal ekonominin hüküm sürdüğü bu dönemdeki, önemlerine vurgu yapar. Bu gerilimi daha iyi ortaya çıkarmak adına bildiri, Sırtlarındaki Hayat ve Demsala Dawî Şewaxan’ı, Sweetgrass (Lucien Castaing-Taylor ve Ilisa Barbash, 2009) ve Leviathan (Lucien Castaing-Taylor ve Verena Paravel, 2012)’la beraber ele alarak karşılaştırmalı olarak analiz eder. Evreni bütüncül bir şekilde, nesne perspektifinden ve derin zaman ekseninde ele alan yeni maddeselciliğin etkileri bu filmlerde ortak bazı eğilimler ortaya koyarken, bir taraftan da yerel bağlama, pratiklere, dillere ve bu bağlamı oluşturan aktörler arasındaki bağlamla ilgili olarak ortaya çıkan ilişkilere yapılan vurgu her filmi kendine özgü kılmaktadır
