Effects of musically-induced emotions on choice reaction time performance
The main objective of the current study was to examine the impact of musically-induced emotions on athletes’ subsequent choice reaction time (CRT) performance. A random sample of 54 tennis players listened to researcher-selected music whose tempo and intensity were modified to yield six different music excerpts (three tempi x two intensities) before completing a CRT task. Affective responses, heart rate (HR), and RTs for each condition were contrasted with white noise and silence conditions. As predicted, faster music tempi elicited more pleasant and aroused emotional states; and higher music intensity yielded both higher arousal (p < .001) and faster subsequent CRT performance (p < .001). White noise was judged significantly less pleasant than all experimental conditions (p < .001); and silence was significantly less arousing than all but one experimental condition (p < .001). The implications for athletes’ use of music as part of a preevent routine when preparing for reactive tasks are discussed
Social workers’ perspectives on the psychosocial needs of families during critical illness
This article reports the needs of relatives whose family member is unexpectedly admitted to an Intensive Care Unit. The Critical Care Family Needs Inventory (CCFNI) was used to measure and rank a series of need statements by family members (n = 25) and social workers (n = 42). Comparative analysis reveals that there were need statements that showed a significant difference in mean scores. Minor differences in both the rank order of individual need statements and the five-factor analysis categories were found. Implications for clinical social work practice are discussed
Sustainable energy in Australia: an analysis of performance and drivers relative to other OECD countries
Deposited with permission from the author. © 2009 Dr. Peter Andrew KinradeHow sustainable is Australia’s pattern of energy supply and use? What are the major factors explaining Australia’s sustainable energy performance relative to other countries? This thesis explores energy supply and use in Australia during the 1990s and 2000s and examines major drivers such as policy decisions, economic structure and trade profile. Performance and drivers in Australia are compared with other OECD countries.
To address the questions posed above, it is first necessary to explore the concepts of ‘sustainable development’ and ‘sustainable energy’ and consider how best to measure sustainable energy performance. Alternative sustainability frameworks and models are examined, with the ‘strong sustainability’ model adopted for this thesis being distinguished from other models in three principal ways: i) it places biophysical constraints on economic activity; ii) it regards certain critical natural capital is being non-substitutable; and iii) it places roughly equal emphasis on intra- and intergenerational equity. The strong sustainability model is operationalised into a series of principles and objectives for energy sustainability, which in turn are used as a basis for systematically developing a suite of sustainable energy indicators. This approach is preferred over other approaches to assessing sustainable energy performance given the study’s focus on measurable objectives and outcomes.
The second part of the thesis is devoted to measuring the sustainable energy performance of Australia and other OECD countries against twelve indicators. Some of the indicators selected are ‘standard’, being quite commonly used in other contexts. A number of the indicators though, are unique or have unique features that increase their validity as measures of strong sustainability. Initial results of the performance assessment suggest that Australia is amongst the weakest performing OECD countries, ranking last of all OECD countries against two of the twelve sustainable energy indicators and in the lower quartile of OECD countries against a further six indicators. Further analysis, combining and weighting indicator scores and country rankings across the 12 indicators confirms Australia’s poor performance. Australia ranks 28th of 30 OECD countries by two different ranking methods and 15th of 16 OECD countries by another two methods. Only the USA ranks consistently lower than Australia. Denmark consistently ranks highest of all countries by all methods.
The third and final part of the thesis examines drivers of sustainable energy performance by Australia and a subset of four OECD countries: Denmark, Germany, the Netherlands and Sweden (OECD 4). The primary basis for OECD 4 selection was strong performance against the sustainable energy indicators, although other criteria including economic structure, trade and demography were also considered. A range of techniques, including factorisation, ‘what if’ analysis and linear regression are used to diagnose the underlying factors driving the performance of Australia and the OECD 4 against the sustainable energy indicators. The analysis is extended to include a qualitative assessment of policy drivers including strategic and institutional settings, energy pricing, electricity market policies, R & D and regulation.
A major conclusion of the thesis based on the analysis is that Australia’s weak sustainable energy performance since 1990, relative to other OECD countries, has been substantially shaped by domestic policy decisions, decisions that were not inevitable given Australia’s economic structure, trade profile, demography, and geography
Coping and family functioning predict longitudinal psychological adaptation of siblings of childhood cancer patients
OBJECTIVE: To assess associations of coping and family functioning with psychosocial adjustment in siblings of pediatric cancer patients at 1, 6, 12, and 24 months after diagnosis. METHODS: Eighty-three siblings (ages 7-19 years) participated. Effects on anxiety, quality of life, behavioral-emotional problems, and emotional reactions to the illness were investigated. Data-analysis was performed with multilevel mixed modeling. RESULTS: Psychosocial functioning was impaired at 1 month but ameliorated over time. Adjustment problems were associated with high family adaptation and cohesion, older age, and female gender. Lower anxiety, insecurity, loneliness, and illness involvement were related to siblings' ability to remain optimistic. Insecurity and illness involvement were positively related to reliance on the medical specialist and a tendency to seek information about the illness. CONCLUSIONS: Siblings of pediatric cancer patients are most affected by the illness in the first months. Children at risk may be identified according to sibling age and gender and according to long-term family adaptation processes and sibling coping abilities
Economic strategies for coastal disaster risk reduction: A case study of Exmouth, Western Australia
Recent major natural disasters in Australia have highlighted how some of the economic costs of living in risk-prone areas are borne by the rest of society. This study used the town of Exmouth, in north-western Australia, to investigate economic strategies for coastal disaster risk reduction, as it typifies expanding development in coastal areas prone to extreme weather events. Using a GIS, coastal inundation scenarios from cyclonic storm-surge were investigated relative to coastal property, infrastructure and shire planning. It showed that some areas developed in the past decade are at high risk of storm-surge inundation. There has been a loss of disastermitigating ecosystem functions as well as increased risk to previously unaffected areas. The extent to which risk perceptions of cyclonic storm-surge inundation and flooding influenced the price buyers paid for residential property in Exmouth over the period 1988-2010 was examined using a Hedonic Price Model. This incorporated dwelling variables, proximity to the coast, cyclone Vance storm-surge and 1-in-100 year flood levels and indicated that prices did not reflect the real societal cost of risk. To internalize these costs, a mandatory private insurance scheme for high-risk properties (with a time-phased government subsidy) and penalties for local councils undertaking new high-risk developments are proposed. Further, a hybrid economic instrument aimed at correcting the market failure in coastal land which comprises an environmental offset by developers, a propertyowner tax and special disaster risk mitigation fund, is also proposed. This study is highly relevant in view of the planned revision of the Western Australian Coastal Planning Policy, the expansion of industry along the coast of northern Australia and the predicted effects of climate change on sea levels and extreme weather events
