Journeys and Transmission

The Land/Water 2016 symposium, Journeys and Transmission, explores contemporary concerns about our relationship to the world, following the journeys we make as artists and researchers to acquire knowledge and to share an understanding of what it is to be human in the post-industrial era of an increasingly globalized and networked twenty first century. These journeys may be personal - understood as a changing consciousness or a sense of identity and selfhood, or an altered subjective space; conceptual - manifested as a paradigm shift within a philosophical framework or ‘thinking outside the box’; or geographic - driven by social, economic or political imperatives. Using an engaged, critical lens, we consider the ways in which creative practitioners respond to the land and the waters that flow through it, translating sensory or digital data into material forms. In addition, we are interested in the manner in which information is conveyed/transmitted across time and place - from one generation of people to another, questioning the appropriation of the past as evidence for the writing of history in relation to its use as the source of stories in the present. Also of relevance are the ways in which ideas are conveyed between practices, or are reshaped in the transmission from one medium to another, or through combination, creating new hybrid forms that extend aesthetic appreciation and cultural critique into new areas

Geometric isomers of chloro(6-methyl-1,4,8,11-tetraazacyclotetradecane-6-amine)cobalt(III) tetrachlorozincate(II)

The crystal structures of a pair of cis and trans isomers of the macrocyclic chloropentaamine title complex, as their tetrachlorozincate(II) salts, [CoCl(C11H27N5)][ZnCl4], are reported. The two distinct isomeric forms lead to significant variations in the Co-N bond lengths and, furthermore, hydrogen bonding between the complex ions is influenced by the folded (cis) or planar (trans) conformations of the coordinated ligand

Seeing with sound? Exploring different characteristics of a visual-to-auditory sensory substitution device

Sensory substitution devices convert live visual images into auditory signals, for example with a web camera (to record the images), a computer (to perform the conversion) and headphones (to listen to the sounds). In a series of three experiments, the performance of one such device (‘The vOICe’) was assessed under various conditions on blindfolded sighted participants. The main task that we used involved identifying and locating objects placed on a table by holding a webcam (like a flashlight) or wearing it on the head (like a miner’s light). Identifying objects on a table was easier with a hand-held device, but locating the objects was easier with a head-mounted device. Brightness converted into loudness was less effective than the reverse contrast (dark being loud), suggesting that performance under these conditions (natural indoor lighting, novice users) is related more to the properties of the auditory signal (ie the amount of noise in it) than the cross-modal association between loudness and brightness. Individual differences in musical memory (detecting pitch changes in two sequences of notes) was related to the time taken to identify or recognise objects, but individual differences in self-reported vividness of visual imagery did not reliably predict performance across the experiments. In general, the results suggest that the auditory characteristics of the device may be more important for initial learning than visual associations

Plans for High Beta Optics in the LHC

ISBN 978-3-95450-115-1 - http://accelconf.web.cern.ch/AccelConf/IPAC2012/papers/moppc007.pdfInternational audienceBased on what has been learned with the first high β* = 90 m operation in 2011, we describe the potential and practical scenarios for reaching very high β* in the LHC in 2012 and beyond. Very high β* optics require dedicated running time and conditions in the LHC. We describe a plan which is optimized to maximize the physics potential in a minimum of dedicated running time

Interaction of Supernova Ejecta with Nearby Protoplanetary Disks

The early Solar System contained short-lived radionuclides such as 60Fe (t1/2 = 1.5 Myr) whose most likely source was a nearby supernova. Previous models of Solar System formation considered a supernova shock that triggered the collapse of the Sun's nascent molecular cloud. We advocate an alternative hypothesis, that the Solar System's protoplanetary disk had already formed when a very close (< 1 pc) supernova injected radioactive material directly into the disk. We conduct the first numerical simulations designed to answer two questions related to this hypothesis: will the disk be destroyed by such a close supernova; and will any of the ejecta be mixed into the disk? Our simulations demonstrate that the disk does not absorb enough momentum from the shock to escape the protostar to which it is bound. Only low amounts (< 1%) of mass loss occur, due to stripping by Kelvin-Helmholtz instabilities across the top of the disk, which also mix into the disk about 1% of the intercepted ejecta. These low efficiencies of destruction and injectation are due to the fact that the high disk pressures prevent the ejecta from penetrating far into the disk before stalling. Injection of gas-phase ejecta is too inefficient to be consistent with the abundances of radionuclides inferred from meteorites. On the other hand, the radionuclides found in meteorites would have condensed into dust grains in the supernova ejecta, and we argue that such grains will be injected directly into the disk with nearly 100% efficiency. The meteoritic abundances of the short-lived radionuclides such as 60Fe therefore are consistent with injection of grains condensed from the ejecta of a nearby (< 1 pc) supernova, into an already-formed protoplanetary disk.Comment: 57 pages, 16 figure

Linking routinely collected social work, education and health data to enable monitoring of the health and health care of school-aged children in state care (‘looked after children’) in Scotland: a national demonstration project

Background and objectives: Children in state care (‘looked after children’) have poorer health than children who are not looked after. Recent developments in Scotland and elsewhere have aimed to improve services and outcomes for looked after children. Routine monitoring of the health outcomes of looked after children compared to those of their non-looked after peers is currently lacking. Developing capacity for comparative monitoring of population based outcomes based on linkage of routinely collected administrative data has been identified as a priority. To our knowledge there are no existing population based data linkage studies providing data on the health of looked after and non-looked after children at national level. Smaller scale studies that are available generally provide very limited information on linkage methods and hence do not allow scrutiny of bias that may be introduced through the linkage process. Study design and methods: National demonstration project testing the feasibility of linking routinely collected looked after children, education, and health data. Participants: All children in publicly funded school in Scotland in 2011/12. Results: Linkage between looked after children data and the national pupil census classified 10,009 (1.5%) and 1,757 (0.3%) of 670,952 children as, respectively, currently and previously looked after. Recording of the unique pupil identifier (Scottish Candidate Number, SCN) on looked after children returns is incomplete, with 66% of looked after records for 2011/12 for children of possible school age containing a valid SCN. This will have resulted in some under-ascertainment of currently and, particularly, previously looked after children within the general pupil population. Further linkage of the pupil census to the NHS Scotland master patient index demonstrated that a safe link to the child’s unique health service (Community Health Index, CHI) number could be obtained for a very high proportion of children in each group (94%, 95%, and 95% of children classified as currently, previously, and non-looked after respectively). In general linkage rates were higher for older children and those living in more affluent areas. Within the looked after group, linkage rates were highest for children with the fewest placements and for those in permanent fostering. Conclusions: This novel data linkage demonstrates the feasibility of monitoring population based health outcomes of school aged looked after and non-looked after children using linked routine administrative data. Improved recording of the unique pupil identifier number on looked after data returns would be beneficial. Extending the range of personal identifiers on looked after children returns would enable linkage to health data for looked after children who are not in publicly funded schooling (i.e. those who are pre- or post-school, home schooled, or in independent schooling)

Chinese medicine in the West 2009

In January 1985 The Journal of Chinese Medicine published an edited transcript of a discussion called ‘Acupuncture in the West’ between Peter Deadman, Ted Kaptchuk, Giovanni Maciocia and Felicity Moir. It was a particularly popular article and to celebrate the 30th anniversary of the JCM we decided to convene another discussion, in London in March 2009. Present this time were Peter Deadman (PD), Hugh MacPherson (HM), Daniel Maxwell (DM), Felicity Moir (FM) and Volker Scheid (VS). All are past or present practitioners of acupuncture and/or herbal medicine

The Association Between Discrimination and Sleep is Exacerbated in Individuals with Comorbid Chronic Health Conditions

Introduction: The consequences of recurrent, stressful daily experiences for sleep health appear intensified in individuals with pre-existing health conditions. Although discrimination has been associated with sleep outcomes, the role of comorbid chronic health conditions (CCHCs), and impact of perceived discrimination, remains unclear. The present study investigated (1) the associations between daily discrimination and sleep and (2) moderating roles of CCHCs and daily life interference and hardship. Methods: The current study utilized archival data from the Midlife in the United States (MIDUS) Study II. Participants, 174 adults (51% female, Mage=57 yrs., SD=11.5 yrs.), completed 7 days of actigraphy, sleep diary, PSQI, and CCHC-reporting measures. Models examined the moderating effects of CCHCs, daily interference, and hardship on the association between discrimination and sleep. Results: Daily discriminatory experiences predicted numerous poor sleep outcomes, exacerbated for persons with higher CCHCs. Higher comorbidity (95% CI=5.40, 68.75) exacerbated the association between discrimination and TSTactigraphy, further strengthened by perceived hardship (95% CI=-3.75, -.40) and interference (95% CI=-3.65, -.30). Number of CCHCs, qualified by perceived hardship (95% CI=.00, .04) and interference (95% CI=.01, .05), predicted diary sleep quality above discrimination. The interaction between CCHCs and hardship predicted global PSQI scores (95% CI=-.91, -.12) beyond discrimination. Conclusion: Daily experiences of discrimination are associated with decreased sleep duration and quality. These associations were stronger for individuals with multiple CCHCs. Exacerbating CCHC effects were perpetuated by perceived interference and hardships, suggesting individual emotion regulation (ER) differences. Future research should attend to sleep-related consequences of differential discrimination-informed ER by persons with CCHCs.https://scholarscompass.vcu.edu/gradposters/1042/thumbnail.jp
