A support worker's guide to models of living and nursing

As a follow-up to the author’s recent thoughts on ‘understanding the nursing process’ (Stonehouse, 2017), this article examines the two complementary models of Roper, Logan and Tierney (1980): their model of living and model of nursing. The different components which make up the two models will be explored and related to clinical practice. It is important for support workers to understand both models and how they are being used within their clinical environment. Through support workers examining different models will assist in achieving section 6 of The Code of Conduct for Healthcare Support Workers and Adult Social Care Workers in England (Skills for Care and Skills for Health, 2013), which urges employees to ‘strive to improve the quality of healthcare, care and support through continuing professional development’

Access to bank finance for Scottish SMEs.

There is evidence that some SMEs may still face difficulties in accessing bank finance from lenders (CEEDR, 2007). This paper reports an in-depth study into demand and supply side issues relating to access to bank finance by Scottish SMEs and whether there is still market failure associated with good, bankable business cases from SMEs that do not receive finance. We argue that our study utilises innovative methodology and is relatively rare as a robust study in this area. We combine demand side in depth survey analysis of SMEs with supply side analysis by bank managers of real business propositions through verbal protocol analysis. This paper discusses the ability of SMEs to access debt finance from the commercial banks in Scotland, it reports findings from a survey of 51 SMEs that had reported having difficulty raising finance and from interviews with bank managers utilising verbal protocol analysis with validated real SME business proposals to give insights into the decision-making of bank managers in the processing of proposals from SMEs. Theoretically, there are categories of SMEs that may face greater difficulties or contain circumstances in which it is more difficult for bank managers to apply standard decision-making models and these categories are explored to provide a theoretical framework for the investigation. The theoretical framework provides themes for discussion of the findings. These include for example; younger SMEs and owners, rural-based SMEs and manufacturing SMEs. Bank officers were found to follow standard financial models, although considerable discretion could be exercised by senior bank managers often leading to a heavy reliance on personal relationships. Smaller and newer SMEs where discretion was more limited were more likely to face difficulties. The study revealed a number of categories of SMEs that face difficulties, including strong growth SMEs in rural environments, new and young SMES,young entrepreneurs seeking start-up finance and manufacturing SMEs seeking to diversify and finance new product development. Focusing on these categories of SMEs,we analyse survey evidence, in depth case studies and verbal protocol analysis with bank managers to discuss research questions on whether informational effects can lead to market failure in the provision of debt finance, the circumstances in which sound propositions are turned down and whether such circumstances can be prevented. This forms the basis for development of conclusions on the continued existence of a debt gap for certain categories of SMEs and some policy implications

Mutators and long-term molecular evolution of pathogenic Escherichia coli O157:H7.

It has been proposed that an increased mutation rate (indicated by the frequency of hypermutable isolates) has facilitated the emergence of Escherichia coli O157:H7. Analysis of the divergence of 12 genes shows no evidence that the pathogen has undergone an unusually high rate of mutation and molecular evolution

Identifying regions of minimal back-scattering by a relativistically-moving sphere

The far-field back-scattering amplitude of an electric field from a relativistically-moving sphere is analyzed. Contrary to prior research, we do so by expressing the fields in the helicity basis, and we highlight here its advantages when compared to the commonly-considered parity basis. With the purpose of exploring specific scattering phenomena considering relativistic effects, we identify conditions that minimize the back-scattered field, leading to a relativistic formulation of the first Kerker condition. The requirements to be satisfied by the sphere are expressed in terms of Mie angles, which constitute an effective parametrization of any possible optical response a sphere might have. We are able to identify multiple combinations of Mie angles up to octupolar order via gradient-based optimization that satisfy our newly formulated relativistic Kerker condition, yielding minima for the back-scattered energy as low as 0.016% of the average scattered energy. Our results can be extended to involve multiple particles forming a metasurface, potentially having direct implications on the design of light sails as considered by the Breakthrough Starshot Initiative.Comment: 4 figures, 1 table, 9 pages + appendix.

Deep 20-GHz survey of the Chandra Deep Field South and SDSS Stripe 82: source catalogue and spectral properties

We present a source catalogue and first results from a deep, blind radio survey carried out at 20 GHz with the Australia Telescope Compact Array, with follow-up observations at 5.5, 9 and 18 GHz. The Australia Telescope 20 GHz (AT20G) deep pilot survey covers a total area of 5 deg2 in the Chandra Deep Field South and in Stripe 82 of the Sloan Digital Sky Survey. We estimate the survey to be 90 per cent complete above 2.5 mJy. Of the 85 sources detected, 55 per cent have steep spectra [graphic] and 45 per cent have flat or inverted spectra [graphic]. The steep-spectrum sources tend to have single power-law spectra between 1.4 and 18 GHz, while the spectral indices of the flat- or inverted-spectrum sources tend to steepen with frequency. Among the 18 inverted-spectrum [graphic] sources, 10 have clearly defined peaks in their spectra with [graphic] and [graphic]. On a 3-yr time-scale, at least 10 sources varied by more than 15 per cent at 20 GHz, showing that variability is still common at the low flux densities probed by the AT20G-deep pilot survey. We find a strong and puzzling shift in the typical spectral index of the 15–20-GHz source population when combining data from the AT20G, Ninth Cambridge and Tenth Cambridge surveys: there is a shift towards a steeper-spectrum population when going from ~1 Jy to ~5 mJy, which is followed by a shift back towards a flatter-spectrum population below ~5 mJy. The 5-GHz source-count model by Jackson & Wall, which only includes contributions from FRI and FRII sources, and star-forming galaxies, does not reproduce the observed flattening of the flat-spectrum counts below ~5 mJy. It is therefore possible that another population of sources is contributing to this effect

Leven Star deposit: An example of Middle to Late Devonian intrusion-related gold systems in the western Lachlan Orogen, Victoria

This study documents an example of atypical gold mineralisation in the central Victorian gold province of the western Lachlan Orogen, Australia. Unlike the vast majority of orogenic gold deposits in this region, the Leven Star deposit at Malmsbury is characterised by a disseminated-stockwork style of mineralisation, a close spatial and temporal association with post-tectonic felsic intrusions, complex alteration characteristics and a Au-As-Sb (±Bi-Te-Cu-Zn-Pb-Sn-W) ore assemblage. In contrast to orogenic-style, metamorphism-related gold mineralisation (ca 440 Ma), which pre-dated magmatism in the western Lachlan Orogen by tens of millions of years, ore formation in the Leven Star deposit was synchronous with, and is paragenetically younger than, Middle to Late Devonian (ca 370 Ma) magmatism. On the basis of these timing relationships, as well as whole-rock geochemistry, and structural, petrographic and fluid-inclusion data, it is suggested that the Leven Star deposit is not orogenic in character and instead should be classified as intrusion-related. © Geological Society of Australia.C

Vascular uptake of rehydration fluids in hypohydrated men at rest and exercise

The purpose of this study was to formulate and to evaluate rehydration drinks, which would restore total body water and plasma volume (PV), for astronauts to consume before and during extravehicular activity, a few hours before reentry, and immediately after landing. In the first experiment (rest, sitting), five healthy men (23-41 yr), previously dehydrated for 24 hr., drank six (1a, 2, 4, 5, 6, 7) fluid formulations (one each at weekly intervals) and then sat for 70 min. Pre-test PV were measured with Evans blue dye and changes in PV were calculated with the hematocrit-hemoglobin transformation equation. This rest experiment simulated hypohydrated astronauts preparing for reentry. The second experiment (exercise, supine) followed the same protocol except four healthy men (30-46 yr) worked for 70 min. in the supine position on a cycle ergometer at a mean load of 71+/-1 percent of their peak aerobic work capacity. This exercise experiment simulated conditions for astronauts with reduced total body water engaging in extravehicular activity

Liquid racism and the Danish Prophet Muhammad cartoons

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2010 The Author.This article examines reactions to the October 2005 publication of the Prophet Muhammad cartoons in the Danish newspaper Jyllands-Posten. It does so by using the concept of ‘liquid racism’. While the controversy arose because it is considered blasphemous by many Muslims to create images of the Prophet Muhammad, the article argues that the meaning of the cartoons is multidimensional, that their analysis is significantly more complex than most commentators acknowledge, and that this complexity can best be addressed via the concept of liquid racism. The article examines the liquidity of the cartoons in relation to four readings. These see the cartoons as: (1) a criticism of Islamic fundamentalism; (2) blasphemous images; (3) Islamophobic and racist; and (4) satire and a defence of freedom of speech. Finally, the relationship between postmodernity and the rise of fundamentalism is discussed because the cartoons, reactions to them, and Islamic fundamentalism, all contain an important postmodern dimension.ESR
