Lines of beauty: propaganda, the poster, and the pictorial trope

Propaganda conceived for distribution via the medium of the pictorial poster creates artwork that can be productively examined from an aesthetic as well as political perspective. When this artwork is primarily restricted to conflict propaganda from the second decade of the twentieth century, the temporal and contextual considerations assist in focussing the poster’s role as a functional object, not only within a propaganda campaign but also within the wider visual ecology of an era.For the poster to operate as an effective means of propaganda distribution, the propagandist requires composition that incorporates constructs capable of attracting the viewer. In isolating a particular construct, its manifestation has the potential to be utilised as a tool in the unpacking of the imagery; consequently the concept of a propagandist promotion of an alternate reality as a challenge to a current real, and the prospective movement from one to the other, can be literally and figuratively conveyed via its employment as a pictorial trope. In this regard, the construct deemed to represent not only movement, but movement at its most beautiful thereby forming a focus for attraction, is the serpentine curve that in 1745 William Hogarth scribed and titled the line of beauty (Hogarth, 1997 p6).In concentrating on the poster within the wider genre of early twentieth century visual conflict propaganda, and creating new associations with aesthetic and metaphoric concepts pertaining to the line of beauty, this research becomes the articulation of how each contributory element within the artwork’s construction ‘respectively influences the identity and the economies of the other’, thereby providing ‘a model by which to focus and rethink’ these relationships (Ostrow, 2005 p226). The line of beauty serves as both cause and effect of the process by which the relationships are reconsidered, thus provoking an innovative discourse as to the potential impact of the whole upon the visual culture field

This paper’s aim is to capture and examine the perceptions of the public by adding insight into what is understood by the terms and disciplines of ‘digital forensics’ and ‘cyber security’. While cyber security and digital forensics can be recognised by their interdisciplinary nature, the two disciplines are distinct in their approach to criminality. At its simplest, cyber security is concerned with the prevention of an incident and implementation of robust systems, while digital forensics focuses on the response to crime and recovering digital evidence. Public perceptions of these areas are important, as security of systems and digital technologies have been heightened in recent years due to high profile cases where notable and large corporations have seen breaches of sensitive information. This study draws on responses from the public using an online survey taken by 102 participants that asked their views on cyber security and digital forensics. This paper demonstrates that there is an awareness among respondents of both disciplines where participants have associated cyber security predominately with the protection of data and systems and digital forensics as the examination and inspection of digital devices. Additionally, responses have also shown there is a need for further awareness in these fields.Peer reviewe

Segregation in High Concentration Flows

Sand injectites are observed in a wide range of locations and settings, both modern and ancient but little is known about the processes controlling their formation. The scale of these injections range from mm to km in size and represent the forceful injection of fluidised sand into host strata. Due to the difficulty of observing in-situ events and relative paucity of outcrop data interpretations, understanding of the flow processes during fluidisation pipe formation is lacking. Existing fluidisation models provide mechanisms for fluidisation but remain simplistic and do not capture the full dynamics nor the range of characteristics which are observed to vary both spatially and temporally across the system during the formation of sand injectites. Fluidisation theory relies on an understanding of both the velocity characteristics and the concentration characteristics of a fluidisation event but comprehensive evidence of these quantities has not previously been available. The novel application of experimental techniques in both two dimensions and three dimensions in this thesis provides both high resolution velocity data for the formation and quasi-steady state of fluidisation pipes along with high resolution concentration data for the first time. Complementing this, the novel application of numerical modelling provides insight into the early stages of void formation and demonstrates a new methodology for investigating flow processes during fluidisation. The products of the fluidisation events modelled are presented providing a direct link between fluidisation processes and products for reference in interpreting outcrop data. Residual morphologies are evidenced resulting in explanations of the poor detection rate of sand injections. New models of fluidisation and void formation are presented based on the extensive characterisation of a fluidisation event achieved across multiple methodologies

A simple, space constrained NIRIM type reactor for chemical vapour deposition of diamond

In this paper the design of a simple, space constrained chemical vapour deposition reactor for diamond growth is detailed. Based on the design by NIRIM, the reactor is composed of a quartz discharge tube placed within a 2.45 GHz waveguide to create the conditions required for metastable growth of diamond. Utilising largely off-the-shelf components and a modular design, the reactor allows for easy modification, repair, and cleaning between growth runs. The elements of the reactor design are laid out with the CAD files, parts list, and control files made easily available to enable replication. Finally, the quality of nanocrystalline diamond films produced are studied with SEM and Raman spectroscopy, with the observation of clear faceting and a large diamond fraction suggesting the design offers deposition of diamond with minimal complexity

Superconducting Diamond on Silicon Nitride for Device Applications

Chemical vapour deposition (CVD) grown nanocrystalline diamond is an attractive material for the fabrication of devices. For some device architectures, optimisation of its growth on silicon nitride is essential. Here, the effects of three pre-growth surface treatments, often employed as cleaning methods of silicon nitride, were investigated. Such treatments provide control over the surface charge of the substrate through modification of the surface functionality, allowing for the optimisation of electrostatic diamond seeding densities. Zeta potential measurements and X-ray photoelectron spectroscopy (XPS) were used to analyse the silicon nitride surface following each treatment. Exposing silicon nitride to an oxygen plasma offered optimal surface conditions for the electrostatic self-assembly of a hydrogen-terminated diamond nanoparticle monolayer. The subsequent growth of boron-doped nanocrystalline diamond thin films on modified silicon nitride substrates under CVD conditions produced coalesced films for oxygen plasma and solvent treatments, whilst pin-holing of the diamond film was observed following RCA-1 treatment. The sharpest superconducting transition was observed for diamond grown on oxygen plasma treated silicon nitride, demonstrating it to be of the least structural disorder. Modifications to the substrate surface optimise the seeding and growth processes for the fabrication of diamond on silicon nitride devices

Is the infant car seat challenge useful?:A pilot study in a simulated moving vehicle

Background and objective The American Academy of Pediatrics recommends that preterm infants complete a predischarge 'car seat challenge' observation for cardiorespiratory compromise while in a car seat. This static challenge does not consider the more upright position in a car or the vibration of the seat when the car is moving. This pilot study was designed to assess the cardiorespiratory effects of vibration, mimicking the effect of being in a moving car, on preterm and term infants. Methods A simulator was designed to reproduce vertical vibration similar to that in a rear-facing car seat at 30 mph. 19 healthy newborn term and 21 preterm infants, ready for hospital discharge, underwent cardiorespiratory measurements while lying flat in a cot (baseline), static in the seat (30°), simulator (40°) and during motion (vibration 40°). Results Median test age was 13 days (range 1-65 days) and median weight was 2.5 kg (IQR: 2.1-3.1 kg). Compared with baseline observations, only the total number of desaturations was significantly increased when infants were placed at 30° (p=0.03). At 40°, or with vibration, respiratory and heart rates increased and oxygen saturation decreased significantly. Profound desaturations &lt;85% significantly increased during motion, regardless of gestational age. Conclusions This is the first study to assess the effect of motion on infants seated in a car safety seat. Term and preterm infants showed significant signs of potentially adverse cardiorespiratory effects in the upright position at 40°, particularly with simulated motion, not identified in the standard challenge. A larger study is required to investigate the significance of these results.</p

An evaluation of seasonal variations in footwear worn by adults with inflammatory arthritis: a cross-sectional observational study using a web-based survey

Background: Foot problems are common in adults with inflammatory arthritis and therapeutic footwear can be effective in managing arthritic foot problems. Accessing appropriate footwear has been identified as a major barrier, resulting in poor adherence to treatment plans involving footwear. Indeed, previous New Zealand based studies found that many people with rheumatoid arthritis and gout wore inappropriate footwear. However, these studies were conducted in a single teaching hospital during the New Zealand summer therefore the findings may not be representative of footwear styles worn elsewhere in New Zealand, or reflect the potential influence of seasonal climate changes. The aim of the study was to evaluate seasonal variations in footwear habits of people with inflammatory arthritic conditions in New Zealand. Methods: A cross-sectional study design using a web-based survey. The survey questions were designed to elicit demographic and clinical information, features of importance when choosing footwear and seasonal footwear habits, including questions related to the provision of therapeutic footwear/orthoses and footwear experiences. Results: One-hundred and ninety-seven participants responded who were predominantly women of European descent, aged between 46–65 years old, from the North Island of New Zealand. The majority of participants identified with having either rheumatoid arthritis (35%) and/or osteoarthritis (57%) and 68% reported established disease (>5 years duration). 18% of participants had been issued with therapeutic footwear. Walking and athletic shoes were the most frequently reported footwear type worn regardless of the time of year. In the summer, 42% reported wearing sandals most often. Comfort, fit and support were reported most frequently as the footwear features of greatest importance. Many participants reported difficulties with footwear (63%), getting hot feet in the summer (63%) and the need for a sandal which could accommodate a supportive insole (73%). Conclusions: Athletic and walking shoes were the most popular style of footwear reported regardless of seasonal variation. During the summer season people with inflammatory arthritis may wear sandals more frequently in order to accommodate disease-related foot deformity. Healthcare professionals and researchers should consider seasonal variation when recommending appropriate footwear, or conducting footwear studies in people with inflammatory arthritis, to reduce non-adherence to prescribed footwear

Catalytic Synergy Using Al(III) and Group 1 Metals to Accelerate Epoxide and Anhydride Ring-Opening Copolymerizations

The controlled synthesis of polyesters via epoxide/anhydride ring-opening copolymerization is a versatile and generally applicable method to make many sustainable polymers, but catalyst activities are limited and the required catalyst loadings are typically high. Here, novel heterodinuclear complexes, featuring Al(III)/M(I) (M = Na, K, Rb, Cs), show exceptional activities for phthalic anhydride and cyclohexene oxide copolymerization (catalyst = Al(III)/K(I), turnover frequency = 1072 h–1, 0.25 mol % catalyst loading vs anhydride, 100 °C). The Al(III)/K(I) catalyst is also tolerant to low loadings, maintaining a good performance at 0.025 mol % catalyst vs anhydride loading and 0.005 mol % vs epoxide. It rapidly polymerizes other epoxide/anhydride combinations yielding various semi-aromatic, rigid, and/or functionalizable polyesters and also shows activity in carbon dioxide/epoxide copolymerizations. The results of structure–activity, X-ray crystallography, polymerization kinetics, and density functional theory investigations support a mechanism with chain growth alternation between the metals. The rate-limiting step is proposed to involve epoxide coordination at Al(III) with K(I) carboxylate attack. Future exploitation of abundant and inexpensive Group 1 metals to deliver synergic polymerization catalysts is recommended

Age-dependent effect of APOE and polygenic component on Alzheimer's disease

Alzheimer’s disease (AD) is a devastating neurodegenerative condition with significant genetic heritability. Several genes have been implicated in the onset of AD with the apolipoprotein E (APOE) gene being the strongest single genetic risk loci. Evidence suggests that the effect of APOE alters with age during disease progression. Here, we aim to investigate the impact of APOE and other variants outside the APOE region on AD risk in younger and older participants. Using data from both the Alzheimer’s Disease Neuroimaging Initiative (ADNI) and the UK Biobank (UKBB) we computed the polygenic risk score (PRS) of each individual informed by the latest genetic study from the International Genomics of Alzheimer’s Project (IGAP). Our analysis showed that the effect of APOE on the disease risk is greater in younger participants and reduces as participant age increases. Our findings indicate the increased impact of PRS as participant age increases. Therefore, AD in older individuals can potentially be triggered by the cumulative effect of genes which are outside the APOE region
