River and coast: regionality in North Kimberley rock art

The aim of this thesis is to examine regionality in the rock art of the north Kimberley, Western Australia. The region is renowned for its art of polychrome Wandjina figures, totemic ancestors and creators of the land for modern West Kimberley people. Underlying them are smaller, elegantly painted human figures. These are Bradshaw Figures or the Gwion Gwion as they are increasingly being called. The figures are decorated as if for dancing with waist mounted tassels, sashes and elaborately decorated headdresses, and an elaborate stylistic chronology has been prepared for the Kimberley art sequence. What is missing from the literature and what this thesis aims to fulfil, is knowledge of regionality and changes in the distribution of the body of art. Some the earliest art is from what I term the Early Phase and is thought to date to a time of aridity near the height of the ice age in Australia. Successive art periods may have occurred at times of changing climate as sea levels rose at the end of the ice age and the ensuing flooding of the exposed coastal plain. The sea level and the shoreline only stabilised in its present day position, and the present climate and environment settled to its current conditions, around 6500 years ago. I argue that the different styles of art and different locations selected in which to paint are related to the situation in the period of flux, when the inhabitants of the Kimberley were affected by changes, including the changes in their territory due to rising sea levels. Two geographically distinct areas were selected which would have been different at the time of painting of the earlier art, one being a river and the other, the coast, as at the time of painting the elegant figures, with retreating shorelines, it would have been inland. My research shows that the painters of Middle Phase art oscillated between permanent water and more transient sources, an effect influenced by their experience of ancient changes in climate

Ranking workplace competencies: Student and graduate perceptions

Students and graduates from a variety of business studies programs at a New Zealand tertiary institution completed a questionnaire in which they ranked the relative importance of a list of 24 competencies for graduates entering the workforce using a 7-point Likert scale. These competencies were identified from literature reports of the characteristics of superior performers in the workplace. The results show a close similarity between students and graduates’ ranking of competencies with computer literacy, customer service orientation, teamwork and co-operation, self-confidence, and willingness to learn ranked most important. There was little difference between the two groups in their rankings of cognitive or ‘hard’ skills and behavioral or ‘soft’ skills. However, the graduates placed greater importance on most of the competencies, resulting in a statistically significant difference between the graduates and students’ ranking of both hard and soft skills. The findings from this study suggest that cooperative education programs may help develop business students’ awareness of the importance of graduate competencies in the workplace

The Spiral that Vanished: The Application of Non-Contact Recording Techniques to an Elusive Rock Art Motif at Castlerigg Stone Circle in Cumbria

This article describes the recording of stone 11 of the Castlerigg stone circle in Cumbria through two different non-contact techniques: laser scanning and ground-based remote sensing. Despite the unproblematic recording of modern graffiti, neither technique was able to document the spiral photographed and rubbed in 1995. It is concluded that the spiral was most probably painted and has since faded away due to natural events. The discovery and loss of of the spiral motif in Castlerigg is seen as a cautionary tale. In particular, it seems to suggest that it is time to take advantage of the novel technologies based on the digitisation of 3D surfaces with millimetre and submillimetre accuracy such as laser scanning and ground-based remote sensing. They offer many advantages to the recording of prehistoric carvings. In addition to avoiding direct contact with the rock surface eliminating the preservation concerns raised by other techniques, both produce high quality images (laser scaning offering a greater potential for this, but at higher cost) having a much higher level of objectivity, and precision and accuracy far beyond those of traditional recording methods such as wax rubbings and scale drawings

The Proportion of Women Who Have a Breast 4 Years after Breast Cancer Surgery: A Population-Based Cohort Study.

BACKGROUND: There are numerous pathways in breast cancer treatment, many of which enable women to retain a breast after treatment. We evaluated the proportion of women who have a breast, either through conserving surgery (BCS) or reconstruction, at 4-years after diagnosis, and how this varied by patient group. METHODS AND FINDINGS: We identified women with breast cancer who underwent initial BCS or mastectomy in English National Health Service (NHS) hospitals between January 2008 and December 2009 using the Hospital Episode Statistics (HES) database. Women were assigned into one of four patient groups depending on their age at diagnosis and presence of comorbidities. The series of breast cancer procedure (BCS, mastectomy, immediate, or delayed reconstruction) undergone by each women was identified over four years, and the proportion of women with a breast calculated. Variation was examined across patient groups, and English Cancer Networks. Between 2008 and 2009, 60,959 women underwent BCS or mastectomy. The proportion with a breast at 4 years was 79.3%, and 64.0%, in women less than 70 years without, and with comorbidities. Whilst in women aged 70 and over without, and with comorbidities, proportions were 52.6%, and 38.2%, respectively. Comorbidities were associated with lower proportions of BCS, but had little effect on reconstruction rates unlike age. Networks variation of 15% or more was found within each patient group, and Cancer Networks tended to have either a high or low proportion across all four patient groups. However, while 14% of women under 70 years had undergone reconstruction, less than 2% of women aged 70 or more had this treatment option. CONCLUSION: The proportion of women diagnosed with breast cancer who retain a breast at 4 years is strongly associated with age, and presence of comorbidities. There was significant variation between Cancer Networks indicating that women's experience in England was dependent on their geographical location of treatment

Vitamin D Supplementation, Serum 25(OH)D Concentrations and Cardiovascular Disease Risk Factors: A Systematic Review and Meta-Analysis

Background: Cardiovascular disease (CVD) risk factors are associated with low serum 25 hydroxyvitamin D (25(OH)D) concentrations in observational studies; however, clinical trial findings are inconsistent.Objective: We assessed the effect of vitamin D supplementation and increased serum 25(OH)D concentrations on CVD risk factors in a systemic review and meta-analysis of randomized controlled trials (RCTs).Design: MEDLINE, CINAHL, EMBASE, and Google Scholar were searched for RCTs that evaluated vitamin D supplementation and cardiovascular outcomes [blood pressure, parathyroid hormone (PTH), serum high-sensitivity C-reactive protein (hs-CRP), total cholesterol, high and low density lipoprotein (HDL and LDL, respectively), triglycerides, peak wave velocity (PWV) and Augmentation Index (AI)] from 1992 through 2017. Meta-analysis was based on a random-effects model and inverse variance method to calculate standardized mean difference (SMD) as effect sizes, followed by a leave-one-out method for sensitivity analysis. Risk of publication bias was assessed using Cochrane checklist and Begg funnel plots. The systematic review is registered as CRD42015025346.Results: We identified 2341 studies from which 81 met inclusion criteria. The meta-analysis indicated a significant reduction in systolic blood pressure (SMD = −0.102 ± 0.04 mmHg, 95% confidence interval (CI), −0.20 to −0.03), diastolic blood pressure (SMD = −0.07 ± 0.03 mmHg, 95% CI, −0.14 to −0.006), serum PTH (SMD = −0.66 ± 0.08 ng/L, 95% CI, −0.82 to −0.49), hs-CRP (SMD = −0.20 ± 0.07 mg/L, 95% CI, −0.34 to −0.06), total cholesterol (SMD = −0.15 ± 0.06 mmol/L, 95% CI, −0.25 to −0.04), LDL (SMD = −0.10 ± 0.05 mmol/L, 95% CI, −0.20 to −0.003), triglycerides (SMD = −0.12 ± 0.06 mmol/L, 95% CI, −0.23 to −0.003) and a significant increase in HDL (SMD = 0.09 ± 0.04 mmol/L, 95% CI, 0.00 to 0.17) with vitamin D supplementation. These findings remained significant in sensitivity analyses for blood pressure, lipid profile, serum PTH, and serum hs-CRP. There was no significant effect of vitamin D supplementation on PWV (SMD = −0.20 ± 0.13 m/s, 95% CI, −0.46 to 0.06, p = 0.14) and AI (SMD = −0.09 ± 0.14%, 95% CI, −0.37 to 0.19, p = 0.52) for vitamin D supplemented groups.Conclusion: These findings suggest that vitamin D supplementation may act to protect against CVD through improving risk factors, including high blood pressure, elevated PTH, dyslipidemia, and inflammation

Evidence on the Impact of International Financial Reporting Standards in New Zealand

Abstract Purpose -This paper examines the financial impact of the adoption of international financial reporting standards (IFRS) on New Zealand (NZ) companies. It analyses the effects of IFRS on the accounting numbers reported in financial statements. It also compares the association of NZ IFRS versus NZ GAAP book value and equity numbers with market values. Design/methodology/approach -The paper examines a sample of New Zealand listed companies that adopted NZ IFRS. Financial statement data under NZ IFRS and the previous generally accepted accounting practice were hand collected from annual reports. The data is analysed using descriptive statistics and linear regression. Findings -Consistent with value relevance results from common-law based countries we find the adoption of IFRS has had little impact in New Zealand on the association between earnings and equity with market values. In fact, there has been a marginal decrease in value relevance. Originality/value -The study examines the impact of a major regulatory change in financial reporting by documenting New Zealand's experience with the changeover. It extends the research of IFRS implementation overseas by providing evidence from Common Law based jurisdictions. The findings are of relevance to the accounting profession and regulators as they debate whether IFRS should be required for to prepare general purpose financial statements for small to medium-sized enterprises

Temporal artery biopsy: time for a rethink on training?

Background Temporal artery biopsy (TAB) is often performed by ophthalmology trainees without direct supervision. The traditional model of ‘see one, do one, teach one’ still prevails in most units. Whilst it is generally a safe procedure, damage to the temporal branch of the facial nerve has been reported when harvesting the frontal branch of the superficial temporal artery. Methods A survey of trainees from Wessex, Wales, London and Severn deaneries was performed to look at current training techniques, anatomical knowledge and practice. Results 38 trainees responded to the survey, with complete responses from 28 participants. Formal teaching of the anatomical considerations in TAB was not reported by any trainee, with informal teaching being standard practice. Whilst 61% of respondents reported having learnt about the anatomical ‘danger zone’ for facial nerve damage, 97% of trainees chose an incision that fell within this zone when given a choice between potential incision sites. Conclusion TAB remains a largely trainee-taught, trainee-performed procedure. Most trainees are not aware of how to avoid the risk of damage to the temporal branch of the facial nerve. We suggest harvesting the parietal branch of the temporal artery via an incision outside the anatomical ‘danger zone’. In our experience, this is an easily taught technique that minimises the potential risk of damage to the frontal branch of the facial nerve

Entrepreneurship Skills Development in Higher Education Courses for Teams Leaders

This article analyses the concept of skills and identifies the skills needed by entrepreneurs to lead their teams. To accomplish these goals, the primary step was to determine the leadership skills developed by the universities in the entrepreneurship and innovation courses and to compare it with the needed skills perceived by entrepreneurs. This research approach is framed in the Management Sciences, and the research problem is anchored to the following research questions: What leadership skills are required by students for them to be effective in entrepreneurial endeavors upon graduation? Are the skills identified by the entrepreneurs sufficiently learned in Universities in Portugal? Does the student work experience, gender or age contribute to a level of leadership skills attainment? The leadership skills identified by the entrepreneurs were pointed out by two focus groups with 15 entrepreneurs and by conceptual content analysis, establishing the existence and frequency of concepts represented by the words or phrases in the entrepreneur's discourse. To verify if those skills are being developed in the entrepreneurship and innovation of higher education courses, an online survey was conducted with the students from the 3rd year of 2016/2017 academic year of several universities. The primary outcome of the research will be a proposal for a model of leadership skills development for students to potentiate their leadership capacity as entrepreneurs
