Staff perspectives of drug use issues among sex-on-premises attendees

Aims: Sex on premises venues (SOPV) have been given considerable attention, in particular when exploring the relationship between SOPV attendance and risk behaviours such as drug use and unsafe sex. Little attention has been given to the perspectives of those who work in these venues.

Methods: Semi-structured interviews were conducted with staff recruited from four SOPV in Sydney, Australia. Content analysis was performed to identify common themes.

Findings: Several themes emerged from the staff interviews. These themes concentrated on particular drugs of concern; interventions in place to deal with substance use and those under the influence; and that drug use among SOP patrons occurred at venues prior to attending SOPV.

Conclusions: Interviews with SOP workers showed that these venues face unique challenges that may not be encountered by other settings. SOPV staff has a detailed understanding of their clientele and their perspectives may be important not only when informing trends in substance use but also the development and distribution of harm reduction materials.

Electrowetting measurements with mercury showing mercury/mica interfacial energy depends on charging

We demonstrate that the interfacial energy between mercury and mica is a function of charge on the mercury surface, decreasing with increasing positive charge. The contact angle of mercury on mica has been measured as a function of potential applied to the mercury, which forms the working electrode of a cell containing either KC1 or NaF electrolyte solution. At high negative applied potentials, a stable aqueous film exists between the mercury and mica surface. As potential is made less negative, the film collapses and mercury partial1 wets the mica at a critical potential, close to the electrocapillary maximum. Upon increasing the potential further (making the Hg surface more and more positive), the contact angle measured within the mercury continually decreases. Electrowetting with mercury is not unexpected since its interfacial tension with the aqueous phase is known to be a function of applied potential. However, the observed decrease goes against the trend expected from the Young equation if only this effect is considered. To explain the data we must allow the mercury/mica interfacial tension also to vary with applied potential. This variation indicates that the mercury surface is positively charged by contact with mica, consistent with known contact electrification between these two materials. The inherent charges at the mercury interfaces with mica and electrolyte solution result in contact angle changes of some tens of degrees with a change in applied potential of half a volt orders of magnitude less than the potentials required to effect comparable changes in other electrowetting systems.

The conceptualisation of operational risk management models

Operational risk is evolving as a specialist field of risk management that must be practiced within all organisations, but currently has a particular relevance to banks. The Basel Committee on Banking Supervision has circulated a consultative paper which, if adopted by nation-state bank supervisors, will impose an operational risk capital charge on banks as part of a new Capital Accord. The definition of operational risk is wide-ranging and creates some unique issues related to the development of appropriate risk management models. This paper conceptualises two distinct operational risk management models; being a predictive model that will result in a known outcome upon its implementation, and a pre-emptive operational risk management model which prepares an organisation in the event that a future risk occurrence results in a disruption to critical business operations.

Charges over book debts in the United Kingdom and Australia : the way forward

Is it possible to create a fixed charge over book debts? This question was recently decided by the House of Lords in National Westminster Bank plc v. Spectrum Plus Limited & Ors [2005] UKHL 41 where the full House was against the idea of a fixed charge on book debts and insisted that only a
floating charge had been created. The law in this area is still vague and uncertain in Australia. This article argues that the financiers and the companies should be given the freedom to decide how they wish to structure their charge documents. The article sets out to argue that it is possible to create a sustained workable fixed charge or even a multiple combination of fixed and floating charge over book debts and argues that this would be the only way for both the financiers and the companies to do business together, in respect to the use of book debts as security for a loan. The author explains how this could be possible and how the proposed model would not deny the statutory priority rights of the preferential creditors.

Fixed and floating charges : the latest conflicting law and how to address the gaps

Structural characterization of novel ionic materials incorporating the bis(trifluoromethanesulfonyl)amide anion

A range of low melting salts of the bis(trifluoromethanesulfonyl)amide (TFSA) anion with hindered organic cations (N-methyl-1-methylpyrrolinium, N,N-dimethylpyrrolidinium, N,N,N,-trimethylammonium, and N,N,N,N-tetrakis(n-propyl)ammonium) have been crystallized. Single-crystal X-ray diffraction data show these materials to consist of discrete ions with only weak C−H···O (or for Me₃NH N−H···O) contacts between the constituent atoms of the cations and anions close to the limits of van der Waals separations. Consequently, the observed physical properties of these materials presumably result from the diffuse negative charge on the TFSA anion and inefficient packing of these large and irregularly shaped ions.

The Australian superannuation framework : implications for retirement savings

The provision of retirement income has become a challenge for governments across the world. The population is ageing as a result of lower mortality and fertility rates: this places financial stress on government budgets as welfare spending increases, further compounded by a proportional reduction in working-age taxpayers. The Australian government has introduced a compulsory superannuation charge on employers to assist retirement savings. Even though savings in superannuation have increased significantly over the years, many will still have insufficient savings to fund their retirement. Recent changes to the superannuation framework have emphasised the importance the government places on supporting future generations of Australians in retirement.

Alcohol-related crime in city entertainment precincts: Public perception and experience of alcohol-related crime and support for strategies to reduce such crime

INTRODUCTION AND AIMS: Bars, pubs and taverns in cities are often concentrated in entertainment precincts that are associated with higher rates of alcohol-related crime. This study assessed public perception and experiences of such crime in two city entertainment precincts, and support for alcohol-related crime reduction strategies. DESIGN AND METHODS: A cross-sectional household telephone survey in two Australian regions assessed: perception and experiences of crime; support for crime reduction strategies; and differences in such perceptions and support. RESULTS: Six hundred ninety-four people completed the survey (32%). Most agreed that alcohol was a problem in their entertainment precinct (90%) with violence the most common alcohol-related problem reported (97%). Almost all crime reduction strategies were supported by more than 50% of participants, including visitors to the entertainment precincts, with the latter being slightly less likely to support earlier closing and restrictions on premises density. Participants in one region were more likely to support earlier closing and lock-out times. Those at-risk of acute alcohol harm were less likely to support more restrictive policies. DISCUSSION AND CONCLUSIONS: High levels of community concern and support for alcohol harm-reduction strategies, including restrictive strategies, provide policy makers with a basis for implementing evidence-based strategies to reduce such harms in city entertainment precincts.

Investigating the affective core of SWB: the circular way

 This thesis builds on premises from the subjective wellbeing homeostasis theoretical framework, and applies constructs from circumplex theories of affect. The findings inform basic affective science by using circumplex modeling and curve-fitting to identify the set-point core affective state associated with normal self-perceptions, and overall life satisfaction.

The association between alcohol outlet density and alcohol use among urban and regional Australian adolescents

AIMS: While recent evidence suggests that higher alcohol outlet density is associated with greater alcohol use among adolescents, influence of the four main outlet types on youth drinking within urban and regional communities is unknown. This study provides the first investigation of this relationship. DESIGN: Repeated cross-sectional surveys with random samples of secondary students clustered by school. Mixed-effects logistic regression analyses examined the association between each outlet type and the drinking outcomes, with interaction terms used to test urban/regional differences. SETTING: Australia, 2002-11. PARTICIPANTS: Respondents participating in a triennial survey (aged 12-17 years); 44 897 from urban settings, 23 311 from regional settings. MEASUREMENTS: The key outcome measures were past month alcohol use, risky drinking among all students and risky drinking among past week drinkers. For each survey year, students were assigned a postcode-level outlet density (number of licences per 1000 population) for each outlet type (general, on-premise, off-premise, clubs). FINDINGS: Interaction terms revealed a significant association between off-premises outlet density and risky drinking among all adolescents in urban (odds ratio = 1.36, 95% confidence interval CI = 1.05-1.75, P < 0.05) but not regional areas. Similarly, club density was associated with the drinking outcomes in urban communities only. General and on-premises density was associated with alcohol use and risky drinking among all adolescents. CONCLUSIONS: Higher densities of general, on- and off-premises outlets in an adolescent's immediate neighbourhood are related to increased likelihood of alcohol consumption among all adolescents. The density of licensed clubs is associated more strongly with drinking for urban than for regional adolescents.

The charge effect of cationic surfactants on the elimination of fibre beads in the electrospinning of polystyrene

Polystyrene nanofibres were electrospun with the inclusion of cationic surfactants, dodecyltrimethylammonium bromide (DTAB) or tetrabutylammonium chloride (TBAC), in the polymer solution. A small amount of cationic surfactant effectively stopped the formation of beaded fibres during the electrospinning. The cationic surfactants were also found to improve the solution conductivity, but had no effect on the viscosity. Only DTAB had an effect on the surface tension of the polymer solution, the surface tension decreasing slightly with an increase in the concentration of DTAB.

The formation of beaded fibres was attributed to an insufficient stretch of the filaments during the whipping of the jet, due to a low charge density. Adding the cationic surfactants improved the net charge density that enhanced the whipping instability. The jet was stretched under stronger charge repulsion and at a higher speed, resulting in an exhaustion of the bead structure. In addition, a polymer/surfactant interaction was found in the polystyrene–DTAB solution system, while this interaction was not found in the polystyrene–TBAC system. The polymer/surfactant interaction led to the formation of thinner fibres than those formed in the absence of the interaction.

The effects of a non-ionic surfactant, Triton X-405, on the electrospun fibres were also studied. The addition of Triton X-405 did not eliminate the fibre beads, but reduced the bead numbers and changed the morphology. Triton X-405 slightly improved the solution conductivity, and had a minor effect on the surface tension, but no effect on the viscosity.
