Identity Cards, Semiotic Instability, and Signs of State Recognition for Indonesian Warias

Following the authoritarian New Order in Indonesia (1965–1998) the state-issued identity card was transformed into a symbol available for reproduction by ordinary citizens. One Indonesian transgender population known as warias used the card to engage with the terms of recognition offered by the state. In 2014, warias in Yogyakarta made organizational membership cards that closely mimicked but did not copy the visual form of the original. Warias efforts to expand the state's bureaucratic form through the manipulation of the symbolic and material qualities of cards raised the possibility that the state did not hold a monopoly over powers of recognition

The Theoretical Astrophysical Observatory: Cloud-Based Mock Galaxy Catalogues

We introduce the Theoretical Astrophysical Observatory (TAO), an online virtual laboratory that houses mock observations of galaxy survey data. Such mocks have become an integral part of the modern analysis pipeline. However, building them requires an expert knowledge of galaxy modelling and simulation techniques, significant investment in software development, and access to high performance computing. These requirements make it difficult for a small research team or individual to quickly build a mock catalogue suited to their needs. To address this TAO offers access to multiple cosmological simulations and semi-analytic galaxy formation models from an intuitive and clean web interface. Results can be funnelled through science modules and sent to a dedicated supercomputer for further processing and manipulation. These modules include the ability to (1) construct custom observer light-cones from the simulation data cubes; (2) generate the stellar emission from star formation histories, apply dust extinction, and compute absolute and/or apparent magnitudes; and (3) produce mock images of the sky. All of TAO's features can be accessed without any programming requirements. The modular nature of TAO opens it up for further expansion in the future.Comment: 17 pages, 11 figures, 2 tables; accepted for publication in ApJS. The Theoretical Astrophysical Observatory (TAO) is now open to the public at https://tao.asvo.org.au/. New simulations, models and tools will be added as they become available. Contact [email protected] if you have data you would like to make public through TAO. Feedback and suggestions are very welcom

Visuo-spatial ability in colonoscopy simulator training

Visuo-spatial ability is associated with a quality of performance in a variety of surgical and medical skills. However, visuo-spatial ability is typically assessed using Visualization tests only, which led to an incomplete understanding of the involvement of visuo-spatial ability in these skills. To remedy this situation, the current study investigated the role of a broad range of visuo-spatial factors in colonoscopy simulator training. Fifteen medical trainees (no clinical experience in colonoscopy) participated in two psycho-metric test sessions to assess four visuo-spatial ability factors. Next, participants trained flexible endoscope manipulation, and navigation to the cecum on the GI Mentor II simulator, for four sessions within 1 week. Visualization, and to a lesser degree Spatial relations were the only visuo-spatial ability factors to correlate with colonoscopy simulator performance. Visualization additionally covaried with learning rate for time on task on both simulator tasks. High Visualization ability indicated faster exercise completion. Similar to other endoscopic procedures, performance in colonoscopy is positively associated with Visualization, a visuo-spatial ability factor characterized by the ability to mentally manipulate complex visuo-spatial stimuli. The complexity of the visuo-spatial mental transformations required to successfully perform colonoscopy is likely responsible for the challenging nature of this technique, and should inform training- and assessment design. Long term training studies, as well as studies investigating the nature of visuo-spatial complexity in this domain are needed to better understand the role of visuo-spatial ability in colonoscopy, and other endoscopic techniques

Serological evidence of exposure to Rickettsia, Bartonella and Ehrlichia spp. in healthy or Leishmania infantum infected dogs from Barcelona

Fifty dogs from the area around Barcelona, Spain, were evaluated for serologic evidence of exposure to vector-borne pathogens. Dirofilaria immitis, Ehrlichiacanis, Borrelia burgdorferi, Leishmania infantum, Bartonella vinsonii subspecies berkhoffi, and Rickettsia rickettsii antigens were used for testing purposes. Seroreactivity was determined in 3 different groups of dogs that were categorized based upon their L infantum infection status: uninfected healthy dogs (group 1), L infantum-infected healthy dogs (group 2), and L infantum-infected dogs with clinical manifestations consistent with leishmaniasis (group 3). Of the 50 dogs included in this study, 49 had serologic evidence of exposure to at least 1 organism for which testing was performed

PCR amplification of Bartonella koehlerae from human blood and enrichment blood cultures

<p>Abstract</p> <p>Background</p> <p>Cats appear to be the primary reservoir host for <it>Bartonella koehlerae</it>, an alpha Proteobacteria that is most likely transmitted among cat populations by fleas (<it>Ctenocephalides felis</it>). <it>Bartonella koehlerae </it>has caused endocarditis in a dog and in one human patient from Israel, but other clinically relevant reports involving this bacterium are lacking. Despite publication of numerous, worldwide epidemiological studies designed to determine the prevalence of <it>Bartonella </it>spp. bacteremia in cats, <it>B. koehlerae </it>has never been isolated using conventional blood agar plates. To date, successful isolation of <it>B. koehlerae </it>from cats and from the one human endocarditis patient has consistently required the use of chocolate agar plates.</p> <p>Results</p> <p>In this study, <it>Bartonella koehlerae </it>bacteremia was documented in eight immunocompetent patients by PCR amplification and DNA sequencing, either prior to or after enrichment blood culture using <it>Bartonella </it>alpha Proteobacteria growth medium. Presenting symptoms most often included fatigue, insomnia, joint pain, headache, memory loss, and muscle pain. Four patients were also infected with <it>Bartonella vinsonii </it>subsp. <it>berkhoffii </it>genotype II. After molecular documentation of <it>B. koehlerae </it>infection in these patients, a serological test was developed and serum samples were tested retrospectively. <it>Bartonella koehlerae </it>antibodies were not detected (titers < 1:16) in 30 healthy human control sera, whereas five of eight patient samples had <it>B. koehlerae </it>antibody titers of 1:64 or greater.</p> <p>Conclusions</p> <p>Although biased by a study population consisting of individuals with extensive arthropod and animal exposure, the results of this study suggest that <it>B. koehlerae </it>bacteremia is more common in immunocompetent people than has been previously suspected. Future studies should more thoroughly define modes of transmission and risk factors for acquiring infection with <it>B. koehlerae</it>. In addition, studies are needed to determine if <it>B. koehlerae </it>is a cause or cofactor in the development of arthritis, peripheral neuropathies or tachyarrhythmias in patients.</p

A comparison of remote therapy, face to face therapy and an attention control intervention for people with aphasia: A quasi-randomised controlled feasibility study

Objective: To test the feasibility of a Randomised Controlled Trial comparing face to face and remotely delivered word finding therapy for people with aphasia Design: A quasi-randomised controlled feasibility study comparing remote therapy delivered from a University lab, remote therapy delivered from a clinical site, face to face therapy and an attention control condition Setting: A University lab and NHS outpatient service Participants: Twenty-one people with aphasia following left hemisphere stroke Interventions: Eight sessions of word finding therapy, delivered either face to face or remotely, were compared to an attention control condition comprising eight sessions of remotely delivered supported conversation. The remote conditions used mainstream video conferencing technology. Outcome measures: Feasibility was assessed by recruitment and attrition rates, participant observations and interviews, and treatment fidelity checking. Effects of therapy on word retrieval were assessed by tests of picture naming and naming in conversation. Results: Twenty-one participants were recruited over 17 months, with one lost at baseline. Compliance and satisfaction with the intervention was good. Treatment fidelity was high for both remote and face to face delivery (1251/1421 therapist behaviours were compliant with the protocol). Participants who received therapy improved on picture naming significantly more than controls (mean numerical gains: 20.2 (remote from University); 41 (remote from clinical site); 30.8 (face to face); 5.8 (attention control); p <.001). There were no significant differences between groups in the assessment of conversation. Conclusions: Word finding therapy can be delivered via mainstream internet video conferencing. Therapy improved picture naming, but not naming in conversation

Time resolved pattern evolution in a large aperture laser

We have measured quasi-instantaneous transverse patterns in a broad aperture laser. Non-ordered patterns yielding to boundary determined regular structures in progressive time-integrated recording are observed. The linear analysis and numerical integration of the full Maxwell-Bloch equations allow us to interpret the features of the experiment. We show that this system being far from threshold cannot be fully understood with a perturbative model.Comment: 7 pages, 5 GIF figures . To be published in Phys. Rev. Let
