A randomized controlled trial of a nurse-administered educational intervention for improving cancer pain management in ambulatory settings

The persistence of negative attitudes towards cancer pain and its treatment suggests there is scope for identifying more effective pain education strategies. This randomized controlled trial involving 189 ambulatory cancer patients evaluated an educational intervention that aimed to optimize patients' ability to manage pain. One week post-intervention, patients receiving the pain management intervention (PMI) had a significantly greater increase in self-reported pain knowledge, perceived control over pain, and number of pain treatments recommended. Intervention group patients also demonstrated a greater reduction in willingness to tolerate pain, concerns about addiction and side effects, being a "good" patient, and tolerance to pain relieving medication. The results suggest that targeted educational interventions that utilize individualized instructional techniques may alter cancer patient attitudes, which can potentially act as barriers to effective pain management.

Pacific Carriers Ltd v BNP Paribas

High Court decision in Pacific Carriers v BNP Paribas, that BNP Paribas was estopped from denying the authority of its manager to sign the documents on its behalf will be a relief to third parties who rely on documents signed for and on behalf of financial institutions - particularly to those involved in the shipping industry who seek letters of indemnity relating to discharge of cargo without production of bills of lading.

Expanding the scope of the social response context model

Descriptive models of social response are concerned with identifying and discriminating between different types of response to social influence. In a previous article (Nail, MacDonald, & Levy, 2000), the authors demonstrated that 4 conceptual dimensions are necessary to adequately distinguish between such phenomena as conformity, compliance, contagion, independence, and anticonformity in a single model. This article expands the scope of the authors' 4-dimensional approach by reviewing selected experimental and cultural evidence, further demonstrating the integrative power of the model. This review incorporates political psychology, culture and aggression, self-persuasion, group norms, prejudice, impression management, psychotherapy, pluralistic ignorance, bystander intervention/nonintervention, public policy, close relationships, and implicit attitudes.

Exploratory modelling of grinding pressure within a compressed particle bed

With increasing industry interest in high pressure roll grinding (HPGR) technology, there is a strong incentive for improved understanding of the nature of grinding pressure that exists in the interior of a compressed particle bed. This corresponds to the crushing region of the HPGR. The relationship between applied pressure (stress) to the particle bed and induced pressure (stress) within particles and at contact points between particles is of particular interest. A detailed parametric investigation is beyond the scope of this exploratory paper. However, this exploratory investigation does suggest some interesting behaviour. The compressed particle bed within an 80 turn diameter piston has been modelled using Particle Flow Code for three dimensions. PFC3D is a discrete element code. The total number of simulated particles was 1225 and 2450 for two beds of different thickness. Particle diameters were uniformly distributed between 4 and 4.5 mm. The results of the simulations show that stress intensity within the simulated particle beds and within the observed particles increased with increase of the applied stress. The intensity of the average vertical stress in the selected particles tended to be comparable with the intensity of the pressure applied to the surface of particle bed and was only occasionally higher. However, the stress at contact points between particles could be several times higher. In a real crusher, such high stress amplification at contacts will quickly decrease due to local crushing and a resultant increase the size of the contact area. Therefore, its significance is likely to be relatively small in an industrial context. The modelling results also suggest that failure within the particle bed will progress from the crushing surface towards the depth of the bed. (c) 2006 Elsevier Ltd. All rights reserved.

Smoking status of Australian general practice patients and their attempts to quit

This paper seeks to report on smoking rates, quit attempt methods and success rates among adult patients attending Australian general practice. A cluster cross-sectional survey was used to survey adult patients (18+), who attended Australian GPs in during 2002 and 2003. Over a quarter of patients (27.3%; 95% CI: 26.0-28.7) were former smokers and one in five (21.5%; 95% CI: 20.1-22.9) were current smokers. Ninety-two percent of former and 80% of current smokers used only one method in their last quit attempt with cold turkey the most common method used by both former (88%) and current (62%) smokers. Overall, success rates varied from 77% for cold turkey to 23% for bupropion. Success rates were re-analysed to consider quit attempts post-bupropion listing, with success rate for cold turkey reduced to 40% while bupropion remained reasonably constant at 21%. By tailoring smoking cessation interventions to a smokers' preparedness to quit, scope exists to increase the pool of smokers offered strategies that are more effective in achieving abstinence and avoiding relapse rather than relying on less effective self-quitting behaviours such as cold turkey.

The self-reported impact of legal and non-legal sanctions on a group of recidivist drink drivers

Concern remains regarding the efficacy of legal sanctions to reduce drink driving behaviours among repeat offenders. The present study examined the impact of traditional legal sanctions (e.g., fines and licence disqualification periods), nonlegal sanctions, alcohol consumption and the frequency of recent offending behaviour(s) on intentions to re-offend for a group of recidivist drink drivers (N=166). The analysis indicated that participants perceived legal sanctions to be severe, but not entirely certain nor swift. In addition, self-reported recent drink driving behaviours and alcohol consumption levels were identified as predictors of future intentions to drink and drive. The findings of the study confirm the popular assumption that some repeat offenders are impervious to the threat and application of legal sanctions and suggests that additional interventions such as alcohol treatment programs are required if the drinking and driving sequence is to be broken for this population.
