Older adults’ safety perceptions of driving situations: Towards a new driving self-regulation scale

The term ‘driving self-restriction’ is used in the road safety literature to describe the behaviour of some older drivers. It includes the notion that older drivers will avoid driving in specific, usually self-identified situations, such as those in which safety is compromised. We sought to identify the situations that older drivers report avoiding; and, to determine the adequacy of a key measure of such behaviour. A sample of 75 drivers aged 65 years and older completed Baldock et al.’s modification of the Driving Habits Questionnaire avoidance items (Baldock et al., 2006), the Driving Behaviour Questionnaire, and open-ended items that elicited written descriptions of the most and least safe driving situation. Consistent with previous results, we found a relatively low level of driving self-restriction and infrequent episodes of aggressive violations. However, when combined with the situation descriptions, these data suggest that Driving Habits Questionnaire did not cover all of the situations that older drivers might choose avoid. We suggest that a new avoidance scale is needed and we present a new item pool that may be used for this purpose.

The regulation of insurance intermediaries in the Australian financial services market

The insurance industry discharges a critical role in the Australian economy and is a significant part of the Australian financial services market. The industry relies upon intermediaries, the principal types being brokers and agents, to promote, arrange and distribute their products and services in the market. The pivotal role that they play in this context and sensitivities associated with the consumer oriented products, such as house and contents insurance, has ensured close regulatory attention. Of particular importance was the passage of the Insurance (Agents and Brokers) Act 1984 (Cth), a comprehensive attempt to address the responsibilities of intermediaries as well as particular problem areas associated with the handling of money. However, with the introduction of financial services and market reform early in the new millennium this insurance intermediary specific regulatory approach was abandoned in favour of a market-wide strategy; that is, market reform was based upon across-the-board licensing, disclosure, conduct and fairness standards, and all financial products and services are now regulated at a generic level under Ch 7 of the Corporations Act 2001 (Cth). This article briefly explores the categories of insurance intermediaries and the relevant distinctions between them but focuses mainly upon the regulatory context in which they operate. This context transcends a strictly legal framework as the regulatory body, the Australian Securities and Investments Commission (ASIC), has sought to inform and guide the market through Policy Statements and Regulatory Guides. The usefulness of these guides as an adjunct to the legislation in explaining the scope and operation of regulatory framework is examined. In addition, the article looks at the self-regulatory and dispute resolution practices in this area and their impact. In conclusion an assessment of this across-the-board regulatory regime is advanced.

Attachment in relation to affect regulation and interpersonal functioning among substance use disorder inpatients

Attachment theory has been conceptualised as an affect regulation theory, proposing that attachment is associated with the expression and recognition of emotions as well as interpersonal functioning. Previous research has reported affect regulation difficulties in substance use disorders and addiction has been considered an attachment disorder. However, scarce empirical research exists on the relationship of attachment in relation to affect regulation and interpersonal functioning in those with substance use problems. Thus, the objective of the present study was to investigate potential associations between attachment, negative mood regulation (NMR) expectancies, fear of intimacy and self-differentiation in substance abusers. The revised adult attachment scale (RAAS), the NMR expectancies scale, the fear of intimacy scale and the differentiation of self inventory were administered to a sample of 100 substance use disorder inpatients. Attachment accounted for significant variance in NMR expectancies and was also a strong predictor of fear of intimacy. The predictive utility of attachment also extended to self-differentiation, suggesting that attachment was strongly related to overall self-differentiation score, Emotional reactivity, Emotional cut-off and I position. These findings support attachment theory suggesting that attachment is associated with and predicts affect regulation abilities and difficulties in interpersonal functioning in a sample of substance use disorder inpatients. The inclusion and assessment of attachment appears to be important in the development of treatment programmes for substance abusing individuals.

TaNF-YB3 is involved in the regulation of photosynthesis genes in Triticum aestivum

Nuclear Factor Y (NF-Y) transcription factor is a heterotrimer comprised of three subunits: NF-YA, NF-YB and NF-YC. Each of the three subunits in plants is encoded by multiple genes with differential expression profiles, implying the functional specialisation of NF-Y subunit members in plants. In this study, we investigated the roles of NF-YB members in the light-mediated regulation of photosynthesis genes. We identified two NF-YB members from Triticum aestivum (TaNF-YB3 & 7) which were markedly upregulated by light in the leaves and seedling shoots using quantitative RT-PCR. A genome-wide coexpression analysis of multiple Affymetrix Wheat Genome Array datasets revealed that TaNF-YB3-coexpressed transcripts were highly enriched with the Gene Ontology term photosynthesis. Transgenic wheat lines constitutively overexpressing TaNF-YB3 had a significant increase in the leaf chlorophyll content, photosynthesis rate and early growth rate. Quantitative RT-PCR analysis showed that the expression levels of a number of TaNF-YB3-coexpressed transcripts were elevated in the transgenic wheat lines. The mRNA level of TaGluTR encoding glutamyl-tRNA reductase, which catalyses the rate limiting step of the chlorophyll biosynthesis pathway, was significantly increased in the leaves of the transgenic wheat. Significant increases in the expression level in the transgenic plant leaves were also observed for four photosynthetic apparatus genes encoding chlorophyll a/b-binding proteins (Lhca4 and Lhcb4) and photosystem I reaction center subunits (subunit K and subunit N), as well as for a gene coding for chloroplast ATP synthase  subunit. These results indicate that TaNF-YB3 is involved in the positive regulation of a number of photosynthesis genes in wheat.

Included by design : a case for regulation for accessible housing in Australia

Accessible housing is a scarce yet much needed commodity in Australia. A national agreement between industry and advocacy groups to a voluntary approach, called the Livable Design program, aims to provide access features in all new housing by 2020. Through a range of awareness raising initiatives, the program is anticipating increased supply by builders and increased demand by home-buyers. However the people who need accessible housing are the least likely and least able to buy it at the point of new sale and average homebuyers do not consider access features as a priority. This approach has not been successful overseas or in Australia in the past. Regulation with incentives supported by education and awareness has provided the best results, yet, regulation typically comes with controversy and resistance from the housing industry. A study is planned to identify how effective the Livable Design program is likely to be, what is likely to hinder it and why regulation is likely to be needed.

Negative Mood Regulation (NMR) expectancies, mood, and affect intensity among clients in substance disorder treatment facilities

Negative mood regulation (NMR) expectancies, stress, anxiety, depression and affect intensity were examined by means of self-report questionnaires in 158 volunteers, including 99 clients enrolled in addiction treatment programs. As expected, addicts reported significantly higher levels of stress, anxiety, depression and affect intensity and lower levels of NMR compared to non-addict controls. NMR was negatively correlated with stress, anxiety, depression and affect intensity. The findings indicate that mood self-regulation is impaired in addicts. Low NMR and high affect intensity may predispose to substance abuse and addiction, or alternatively may reflect chronic drug-induced affective dysregulation.

A restrike waveform predictive model for shunt capacitor bank switching with point-on-wave recommendation

Circuit-breakers (CBs) are subject to electrical stresses with restrikes during capacitor bank operation. Stresses are caused by the overvoltages across CBs, the interrupting currents and the rate of rise of recovery voltage (RRRV). Such electrical stresses also depend on the types of system grounding and the types of dielectric strength curves. The aim of this study is to demonstrate a restrike waveform predictive model for a SF6 CB that considered the types of system grounding: grounded and non-grounded and the computation accuracy comparison on the application of the cold withstand dielectric strength and the hot recovery dielectric strength curve including the POW (point-on-wave) recommendations to make an assessment of increasing the CB remaining life. The simulation of SF6 CB stresses in a typical 400 kV system was undertaken and the results in the applications are presented. The simulated restrike waveforms produced with the identified features using wavelet transform can be used for restrike diagnostic algorithm development with wavelet transform to locate a substation with breaker restrikes. This study found that the hot withstand dielectric strength curve has less magnitude than the cold withstand dielectric strength curve for restrike simulation results. Computation accuracy improved with the hot withstand dielectric strength and POW controlled switching can increase the life for a SF6 CB.

By the day nurses bank up in a casual pool!

We suspect that the array of silly names used to refer to temporary staff worldwide may be indicative of the extent to which these nurses have been relegated to, and we would argue, remain in, a type of underclass – relatively unsupported by employers in terms of professional practice and ipso facto excluded from contributing professionally to team work, practice development, clinical governance and evidence based practice. This may be acceptable to some but in a climate of risk averseness and in the interests of strategic planning we would suggest it is an accident waiting to happen. The recent UK Royal College of Nursing (RCN) (Ball & Pike, 2006) survey of bank and agency nurses brings a welcome focus on a group of nurses that make a significant contribution to the smooth running of health services in many countries.
