The valuation profession in Australia: Profile, analysis and future directions

Like many professions and industries the valuation profession is experiencing a more competitive environment. There is a need to establish where the valuation profession is going and, by definition, where it is now, for strategic planning purposes at both the professional and corporate level. This paper analyses the issues facing the profession in Australia and uses Michael Porter's conceptual framework of 'How Competitive Forces Shape Strategy' to better understand these issues and the direction the industry might take to succeed in an uncertain world. It is suggested that such an analysis could assist the strategic planning of major industry groups including API, RICS, as well as providing a basis for the Universities to consider the needs of the profession in the future

Patterns of symptoms possibly indicative of cancer and associated help-seeking behaviour in a large sample of United Kingdom residents - the USEFUL study

Background.Cancer awareness campaigns aim to increase awareness of the potential seriousness of signs and symptoms of cancer, and encourage their timely presentation to healthcare services. Enhanced understanding of the prevalence of symptoms possibly indicative of cancer in different population subgroups, and associated general practitioner (GP) help-seeking behaviour, will help to target cancer awareness campaigns more effectively.Aim.To determine: i) the prevalence of 21 symptoms possibly indicative of breast, colorectal, lung or upper gastrointestinal cancer in the United Kingdom (UK), including six ‘red flag’ symptoms; ii) whether the prevalence varies among population subgroups; iii) the proportion of symptoms self-reported as presented to GPs; iv) whether GP help-seeking behaviour varies within population subgroups.Methods.Self-completed questionnaire about experience of, and response to, 25 symptoms (including 21 possibly indicative of the four cancers of interest) in the previous month and year; sent to 50,000 adults aged 50 years or more and registered with 21 general practices in Staffordshire, England or across Scotland. Results.Completed questionnaires were received from 16,778 respondents (corrected response rate 34.2%). Almost half (45.8%) of respondents had experienced at least one symptom possibly indicative of cancer in the last month, and 58.5% in the last year. The prevalence of individual symptoms varied widely (e.g. in the last year between near zero% (vomiting up blood) and 15.0% (tired all the time). Red flag symptoms were uncommon. Female gender, inability to work because of illness, smoking, a history of a specified medical diagnosis, low social support and lower household income were consistently associated with experiencing at least one symptom possibly indicative of cancer in both the last month and year. The proportion of people who had contacted their GP about a symptom experienced in the last month varied between 8.1% (persistent cough) and 39.9% (unexplained weight loss); in the last year between 32.8% (hoarseness) and 85.4% (lump in breast). Nearly half of respondents experiencing at least one red flag symptom in the last year did not contact their GP about it. Females, those aged 80+ years, those unable to work because of illness, ex-smokers and those previously diagnosed with a specified condition were more likely to report a symptom possibly indicative of cancer to their GP; and those on high household income less likely.Conclusion.Symptoms possibly indicative of cancer are common among adults aged 50+ years in the UK, although they are not evenly distributed. Help-seeking responses to different symptoms also vary. Our results suggest important opportunities to provide more nuanced messaging and targeting of symptom-based cancer awareness campaigns

The Attitudes about Complex Therapy Scale (ACTS) in Type 2 Diabetes and Cardiovascular Disease: Development, Validity and Reliability

Background: Type 2 diabetes is associated with cardiovascular disease, and patients with both conditions are prescribed complex medication regimens. Aim: The aim was to develop a reliable and valid measure of attitudes associated with the prescription and management of multiple medicines in patients with Type 2 diabetes and cardiovascular disease. Methods: Principal component analysis (PCA) and Cronbach alpha assessed the reliability of the Attitudes about Complex Therapy Scale (ACTS). Examinations of relationships with related measures inform concurrent validity. Questionnaires were sent to a cross-sectional sample of 480 people prescribed multiple medicines for co-morbid Type 2 diabetes. Results: Cronbach alpha was 0.76, indicating the scale had good internal reliability. PCA rotated a four factor model accounting for 37% of the variance. Four subscales identified; 1. Concerns about multiple medicines and increasing numbers of medicines; 2.Anxiety over missed medicines; 3. Desires to substitute medicines and reduce the number of medicines prescribed and; 4. Perceptions related to organising and managing complex therapy. The ACTS showed significant relationships with measures of anxiety, depression, general beliefs about medicines and self-efficacy. Also, the ACTS significantly correlated with adherence to medicines, showing good predictive validity. Conclusion: The ACTS was designed to assess negative attitudes towards complex therapy and multiple medication management. This tool could aid prescribing decisions and may identify people who are intentionally non-adherent to all or some of their medicines

Effect of the proprotein convertase subtilisin/kexin type 9 inhibitor evolocumab on glycemia, body weight, and new-onset diabetes mellitus

Statin therapy modestly increases new-onset diabetes risk. The effect of proprotein convertase subtilisin/kexin type 9 inhibition on new-onset diabetes, glycemia, and weight remains unclear. We studied the effects of the proprotein convertase subtilisin/kexin type 9 inhibitor evolocumab on fasting plasma glucose, glycated hemoglobin, weight, and new-onset diabetes mellitus. We pooled 1-year (48-week) data for participants who had completed an evolocumab parent study before entering an open-label extension (OLE) trial. Data were available for 4,802 participants (1,602 on standard of care [SOC]; 3,200 on evolocumab plus SOC) in 2 OLE trials. Evolocumab lowered low-density lipoprotein cholesterol by approximately 60% compared with SOC alone. Over the first year of the OLE trials, there was no difference in median (Q1, Q3) change in glycated hemoglobin (0.1% [-0.1, 0.2] for both SOC and evolocumab plus SOC) and fasting plasma glucose (0.06 mmol/L [-0.28, 0.38 mmol/L] for SOC and 0.06 mmol/L [-0.28, 0.44 mmol/L] for evolocumab plus SOC). Mean weight change (standard error) at 1 year was -0.1 kg (0.2) on SOC compared with 0.3 kg (0.1) on evolocumab plus SOC. The exposure-adjusted incidence rate (95% confidence intervals) for new-onset diabetes per 100 patient years was 3.7 (2.9 to 4.7) on control/SOC alone and 3.9 (3.2 to 4.6) on evolocumab/evolocumab plus SOC treatment. Glycemic changes observed in 6,430 participants at week 12 in the parent studies were comparable with OLE trial findings. In conclusion, evolocumab therapy has no effect on glucose homeostasis over 1 year of open-label treatment

Carbon Sequestration by Reforesting Legacy Grasslands on Coal Mining Sites

Future carbon management during energy production will rely on carbon capture and sequestration technology and carbon sequestration methods for offsetting non-capturable losses. The present study quantifies carbon sequestration via reforestation using measurements and modeling for recent and legacy surface coal mining grasslands that are re-restored through tree planting. This paper focuses on a case study of legacy coal mining sites in the southern Appalachia the United States. This five million-hectare region has a surface mining footprint of approximately 12% of the land area, and the reclamation method was primarily grassland. The results of the soil carbon sequestration rates for restored forest soils approach 2.0 MgC ha−1 y−1 initially and average 1.0 MgC ha−1 y−1 for the first fifty years after reclamation. Plant, coarse root and litter carbon sequestration rates were 2.8 MgC ha−1 y−1 with plant carbon estimated to equilibrate to 110 MgC ha−1 after forty years. Plant, root and litter carbon stocks are projected to equilibrate at an order of magnitude greater carbon storage than the existing conditions, highlighting the net carbon gain. Reforestation of legacy mine sites shows carbon sequestration potential several orders of magnitude greater than typical land sequestration strategies for carbon offsets. Projections of future scenarios provide results that show the study region could be carbon neutral or a small sink if widespread reforesting during reclamation was implemented, which is contrary to the business-as-usual projections that result in a large amount of carbon being released to the atmosphere in this region

Optical inter-site spin transfer probed by energy and spin-resolved transient absorption spectroscopy

Optically driven spin transport is the fastest and most efficient process to manipulate macroscopic magnetization as it does not rely on secondary mechanisms to dissipate angular momentum. In the present work, we show that such an optical inter-site spin transfer (OISTR) from Pt to Co emerges as a dominant mechanism governing the ultrafast magnetization dynamics of a CoPt alloy. To demonstrate this, we perform a joint theoretical and experimental investigation to determine the transient changes of the helicity dependent absorption in the extreme ultraviolet spectral range. We show that the helicity dependent absorption is directly related to changes of the transient spin-split density of states, allowing us to link the origin of OISTR to the available minority states above the Fermi level. This makes OISTR a general phenomenon in optical manipulation of multi-component magnetic systems. Optically driven spin transfer is the fastest process to manipulate magnetism. Here, the authors show that this process emerges as the dominant mechanism in femtosecond spin dynamics enabling to the engineering of functional magnetic systems for future all optical technologies

Predicting the habitat expansion of the invasive roach Rutilus rutilus (Actinopterygii, Cyprinidae), in Great Britain

The roach is influential ecologically and has a preference for water temperatures >12°C. In this study, we attempted to predict its habitat expansion in response to global warming, hypothesing its increase in Great Britain. Historical data for air temperature over different time scales (annual, seasonal, monthly and daily) and for the presence of roach in Great Britain were used to create four Ecological Niche Models. Mean seasonal air temperature (EncRoach-S) was the best predictor. Using EncRoach-S, two future climate scenarios were tested: a sensitivity test (i.e. incrementally increasing temperature values by 1°C), and using air temperature data from UKCIP 11-member ensemble of climate change projections for 2031–2040, 2061–2070 and 2091–2100. Both approaches predicted an increase in habitat suitability in Great Britain with rising air temperatures but the extent of change differed for England, Wales and Scotland. In England, the rate of expansion was initially slow but rapidly increased mid-century leading to 88% coverage by the century end. In Wales, there was a greater increase by the century end and a similar trend in Scotland. This study supports the conjecture that a rise in air temperature over the next few decades will lead to an increase in potential roach habitat

THE CONTRIBUTION OF ELBOW EXTENSION TO WRIST SPEED IN CRICKET FAST BOWLERS

The purpose of this modelling study was to assess the sensitivity of wrist joint speed to systematic manipulations of empirical elbow joint flexion-extension kinematic profiles. The joint kinematic profiles of 12 cricket fast bowlers were entered into a Forward Kinematic Model and the elbow joint kinematic profiles were subsequently amplified to elicit wrist speed changes. An amplification factor of zero decreased wrist speed by a mean of 8.6% (± 6.9%), whereas an amplification factor of two increased speed by a mean of 8.8% (± 7.1%). An opposite relationship was found for two participants who extended the elbow joint prior to release and it is proposed that an internally rotated humerus will displace the wrist joint posteriorly when the elbow joint is extending
