Speech at the exhibition opening of Metropolis: Rotwang\u27s Robot, Revolution, and Redemption A Selection of Memorabiia Relating to Fritz Lang\u27s 1927 Sci-Fi Fantasy Film. From the Collection of Michael Organ.
Opening speech by Dr Jon Cockburn for the exhibition âMetropolis: Rotwangâs Robot, Revolution, and Redemptionâ. The exhibition contains a selection of memorabilia relating to Fritz Langâs 1927 Sci-Fi fantasy film. The memorabilia is on loan to the Wollongong City Gallery from the collection of Michael Organ. The opening speech reflects on the development and production of the film Metropolis (1927), its reception on first release in Germany and then abroad. The filmâs influence on the genre of science fiction to the present day is noted. The filmâs ambiguous themes are of particular interest especially when considered in the light of world events in the late 1930s and the different career trajectories of the filmâs director, Fritz Lang, and the filmâs screenplay writer Thea von Harbou. However, of equal significance is how the film stands as a case study in archiving, preserving and restoring fragile film media with the aim of recouping the filmâs importance as a work and as a document to the time of its production
The barriers and enabling factors for the uptake of voluntary medical male circumcision among "Coloured" males between the ages of 15 and 49 years in the Cape Town Metropolitan Municipality
Magister Public Health - MPHVoluntary Medical Male Circumcision (VMMC) has been proven to reduce heterosexual HIV transmission to men by approximately 60%. It has been argued that achieving 80% circumcision coverage among males aged 15â49 years within five years and maintaining this coverage rate in subsequent years, could avert 3.4 million new HIV infections within 15 years and generate treatment and care savings of US$16.5 billion. As a result the South African Government plans to circumcise 4.3 million males aged 15 and 49 years by the 2015/2016 financial year. However, in the Western Cape the uptake for circumcision has been poor. While there is not a great deal of knowledge out there about the reasons for the uptake (or lack thereof) of VMMC in the Western Cape, current research focus on Xhosa males
predominantly. However, there is limited research on circumcision among the "Coloured" population of the Western Cape. As the "Coloured" population is the largest group in the Western Cape, this gap in research and knowledge is worth noting. The current study aimed to explore the barriers to and enablers of uptake of VMMC among "Coloured" males between the ages of 15 and 49 years in the Cape Town Metropolitan Municipality. Methodology: The study adopted a qualitative design; semi-structured interviews were conducted with seven key informants, and two focus group discussions with men who had undergone VMMC and men who had chosen not to volunteer to undergo VMMC. Thematic analysis was used to analyse the data. Results: The key enablers to uptake of VMMC were: the desire for improved hygiene; the reduction in the risk of contracting other STIs; the reduction in the risk of contracting HIV; the role of partners and family members who can encourage males to access services; the perceived improvement in the males' sexual experience and performance; and cultural reasons and religious injunction.
On the other hand the key barriers that discouraged "Coloured" participants from accessing the services include: fear, particularly the fear of pain; the experience of the health services and the role of health staff; the six week healing period in which males cannot have sex; the unwillingness to alter the body that they were born with; role of partners and family as discouragers of uptake; the influence of gangsterism on the ability of males to access services offered on a different gang's 'turf'; and, substance abuse. The recommendations in this study focus largely on the need to expand the coverage of VMMC in the Cape Town Metropolitan Municipality and to increase the uptake among "Coloured" males between the ages of 15 and 49 years. . These recommendations essentially involve the need to break down the barriers and to accentuate the enablers. To this end social mobilisation campaigns should not focus solely on HIV prevention but rather on hygiene and improved sexual experience and appearance as well as the cultural and religious
aspects. With regard to the barriers it is essential that any social mobilisation engages with the fear of pain. On method to do this would be through the introduction and expansion of the PrePexâą device. The fear that circumcision could impact on sexual performance and the fear of embarrassment and discomfort the whole process would potentially bring would need to be allayed. In addition it is essential that the health services and health staff are orientated and trained in a way that ensures that the process of circumcision is as easy as possible for the clients.National Research Foundatio
Artefacts in geometric phase analysis of compound materials
The geometric phase analysis (GPA) algorithm is known as a robust and
straightforward technique that can be used to measure lattice strains in high
resolution transmission electron microscope (TEM) images. It is also attractive
for analysis of aberration-corrected scanning TEM (ac-STEM) images that resolve
every atom column, since it uses Fourier transforms and does not require
real-space peak detection and assignment to appropriate sublattices. Here it is
demonstrated that in ac-STEM images of compound materials (i.e. with more than
one atom per unit cell) an additional phase is present in the Fourier
transform. If the structure changes from one area to another in the image (e.g.
across an interface), the change in this additional phase will appear as a
strain in conventional GPA, even if there is no lattice strain. Strategies to
avoid this pitfall are outlined.Comment: 9 pages, 7 figures, Preprint before review, submitted to

Migration and demos in the democratic firm: an extension of the firm-state analogy
Debates around the state-firm analogy as a route to justifying workplace democracy tend towards a static view of both state and firm, and position workplace democracy as the objective. We contend, however, that states and firms are connected to one another in ways that should alter the terms of the debate, and that the achievement of workplace democracy raises a new set of political issues about the demos in the democratic firm and âworker migrationâ at the boundaries of the firm. Our argument thus contains two key steps: First, drawing on an empirical case study of a worker-owned firm, we enrich the state-firm analogy by developing a more dynamic view of both, focussing on the creation of workplace democracies; worker movement in and out of them; the dynamic meanings of âcitizenshipâ within them; and the status of the unemployed in a world of democratic workplaces. We then argue that in moving to a more sociological view of the state, the things we were comparing begin to show their real-world connections to one another. By going beyond the idealised view of states that has distorted the state-firm analogy debates, we arrive at a more robust view of how widespread workplace democracy might reconfigure basic political relationships in society
Push-Edge and Slide-Edge: Scrolling by Pushing Against the Viewport Edge
International audienceEdge-scrolling allows users to scroll a viewport while simultaneously dragging near or beyond a windowâs edge. Common implementations rely on rate control, mapping the distance between the pointer and the edge of the viewport to the scrolling velocity. While ubiquitous in operating systems, edge-scrolling has received little attention, even though previous works suggest that (1) rate control may be suboptimal for isotonic pointing devices like mice and trackpads and (2) space beyond the windowâs edge might be scarce, limiting scrolling control. To address these problems, we developed Push-edge scrolling (and Slide-edge scrolling, its inertial variant), two novel position-based techniques that allow scrolling by âpushingâ against the viewport edge. A controlled experiment shows that our techniques reduce overshoots and offer performance improvements by up to 13% over traditional edge-scrolling
High throughput DNA sequencing to detect differences in the subgingival plaque microbiome in elderly subjects with and without dementia
BACKGROUND: To investigate the potential association between oral health and cognitive function, a pilot study was conducted to evaluate high throughput DNA sequencing of the V3 region of the 16S ribosomal RNA gene for determining the relative abundance of bacterial taxa in subgingival plaque from older adults with or without dementia. METHODS: Subgingival plaque samples were obtained from ten individuals at least 70âyears old who participated in a study to assess oral health and cognitive function. DNA was isolated from the samples and a gene segment from the V3 portion of the 16S bacterial ribosomal RNA gene was amplified and sequenced using an Illumina HiSeq1000 DNA sequencer. Bacterial populations found in the subgingival plaque were identified and assessed with respect to the cognitive status and oral health of the participants who provided the samples. RESULTS: More than two million high quality DNA sequences were obtained from each sample. Individuals differed greatly in the mix of phylotypes, but different sites from different subgingival depths in the same subject were usually similar. No consistent differences were observed in this small sample between subjects separated by levels of oral health, sex, or age; however a consistently higher level of Fusobacteriaceae and a generally lower level of Prevotellaceae was seen in subjects without dementia, although the difference did not reach statistical significance, possibly because of the small sample size. CONCLUSIONS: The results from this pilot study provide suggestive evidence that alterations in the subgingival microbiome are associated with changes in cognitive function, and provide support for an expanded analysis of the role of the oral microbiome in dementia
The role of Comprehension in Requirements and Implications for Use Case Descriptions
Within requirements engineering it is generally accepted that in writing specifications (or indeed any requirements phase document), one attempts to produce an artefact which will be simple to comprehend for the user. That is, whether the document is intended for customers to validate requirements, or engineers to understand what the design must deliver, comprehension is an important goal for the author. Indeed, advice on producing âreadableâ or âunderstandableâ documents is often included in courses on requirements engineering. However, few researchers, particularly within the software engineering domain, have attempted either to define or to understand the nature of comprehension and itâs implications for guidance on the production of quality requirements.
Therefore, this paper examines thoroughly the nature of textual comprehension, drawing heavily from research in discourse process, and suggests some implications for requirements (and other) software documentation. In essence, we find that the guidance on writing requirements, often prevalent within software engineering, may be based upon assumptions which are an oversimplification of the nature of comprehension. Hence, the paper examines guidelines which have been proposed, in this case for use case descriptions, and the extent to which they agree with discourse process theory; before suggesting refinements to the guidelines which attempt to utilise lessons learned from our richer understanding of the underlying discourse process theory. For example, we suggest subtly different sets of writing guidelines for the different tasks of requirements, specification and design
Extrafollicular plasmablast present in the acute phase of infections express high levels of PD-L1 and are able to limit T cell respose
During infections with protozoan parasites or some viruses, T cell immunosuppression is generated simultaneously with a high B cell activation. It has been described that, as well as producing antibodies, plasmablasts, the differentiation product of activated B cells, can condition the development of protective immunity in infections. Here, we show that, in T. cruzi infection, all the plasmablasts detected during the acute phase of the infection had higher surface expression of PD-L1 than other mononuclear cells. PD-L1hi plasmablasts were induced in vivo in a BCR-specific manner and required help from Bcl-6+CD4+T cells. PD-L1hi expression was not a characteristic of all antibody-secreting cells since plasma cells found during the chronic phase of infection expressed PD-L1 but at lower levels. PD-L1hi plasmablasts were also present in mice infected with Plasmodium or with lymphocytic choriomeningitis virus, but not in mice with autoimmune disorders or immunized with T cell-dependent antigens. In vitro experiments showed that PD-L1hi plasmablasts suppressed the T cell response, partially via PD-L1. Thus, this study reveals that extrafollicular PD-L1hi plasmablasts, whose peaks of response precede the peak of germinal center response, may have a modulatory function in infections, thus influencing T cell response.Fil: Gorosito Serran, Melisa.

Consistency, completeness and external validity of ethnicity recording in NHS primary care records: a cohort study in 25 million patientsâ records at source using OpenSAFELY
Background: Ethnicity is known to be an important correlate of health outcomes, particularly during the COVID-19 pandemic, where some ethnic groups were shown to be at higher risk of infection and adverse outcomes. The recording of patientsâ ethnic groups in primary care can support research and efforts to achieve equity in service provision and outcomes; however, the coding of ethnicity is known to present complex challenges. We therefore set out to describe ethnicity coding in detail with a view to supporting the use of this data in a wide range of settings, as part of wider efforts to robustly describe and define methods of using administrative data. Methods: We describe the completeness and consistency of primary care ethnicity recording in the OpenSAFELY-TPP database, containing linked primary care and hospital records in > 25 million patients in England. We also compared the ethnic breakdown in OpenSAFELY-TPP with that of the 2021 UK census. Results: 78.2% of patients registered in OpenSAFELY-TPP on 1 January 2022 had their ethnicity recorded in primary care records, rising to 92.5% when supplemented with hospital data. The completeness of ethnicity recording was higher for women than for men. The rate of primary care ethnicity recording ranged from 77% in the South East of England to 82.2% in the West Midlands. Ethnicity recording rates were higher in patients with chronic or other serious health conditions. For each of the five broad ethnicity groups, primary care recorded ethnicity was within 2.9 percentage points of the population rate as recorded in the 2021 Census for England as a whole. For patients with multiple ethnicity records, 98.7% of the latest recorded ethnicities matched the most frequently coded ethnicity. Patients whose latest recorded ethnicity was categorised as Other were most likely to have a discordant ethnicity recording (32.2%). Conclusions: Primary care ethnicity data in OpenSAFELY is present for over three quarters of all patients, and combined with data from other sources can achieve a high level of completeness. The overall distribution of ethnicities across all English OpenSAFELY-TPP practices was similar to the 2021 Census, with some regional variation.
