Paradoxes of participation : non-union workplace partnerships in John Lewis

The extent to which workplace partnership delivers mutual gains is subject to considerable debate amongst practitioners and scholars. One of the oldest and largest examples of workplace partnership is the John Lewis Partnership that began using forms of non-union employee representation in 1929. Despite ongoing interest from researchers in employee representation, and specifically non-union forms of employee voice, there have been few in-depth studies of the Partnership's organisational structure and practices since the 1980s. This paper explores in detail the operation of representation structures in the John Lewis Partnership, which is a significant case of non-union workplace partnership with the potential for mutual gains. A key finding of the paper was that the decision-making structures that characterise the Partnership, and that are protected by a constitution, are under constant threat from the discursive struggle to define partnership in a way that privileges managerial interests. The paper argues, therefore, that mutual gains need to be secured both structurally and discursively to address the tensions and paradoxes at the heart of debates about the meaning and aims of employee representation.

Upper-body morbidity after breast cancer : incidence and evidence for evaluation, prevention, and management within a prospective surveillance model of care

The purpose of this paper is to review the incidence of upper-body morbidity (arm and breast symptoms, impairments, and lymphedema), methods for diagnosis, and prevention and treatment strategies. It was also the purpose to highlight the evidence base for integration of prospective surveillance for upper-body morbidity within standard clinical care of women with breast cancer. Between 10% and 64% of women report upper-body symptoms between 6 months and 3 years after breast cancer, and approximately 20% develop lymphedema. Symptoms remain common into longer-term survivorship, and although lymphedema may be transient for some, those who present with mild lymphedema are at increased risk of developing moderate to severe lymphedema. The etiology of morbidity seems to be multifactorial, with the most consistent risk factors being those associated with extent of treatment. However, known risk factors cannot reliably distinguish between those who will and will not develop upper-body morbidity. Upper-body morbidity may be treatable with physical therapy. There is also evidence in support of integrating regular surveillance for upper-body morbidity into the routine care provided to women with breast cancer, with early diagnosis potentially contributing to more effective management and prevention of progression of these conditions.

A meta-analysis of genome-wide association studies to identify prostate cancer susceptibility loci associated with aggressive and non-aggressive disease

Genome-wide association studies (GWAS) have identified multiple common genetic variants associated with an increased risk of prostate cancer (PrCa), but these explain less than one-third of the heritability. To identify further susceptibility alleles, we conducted a meta-analysis of four GWAS including 5953 cases of aggressive PrCa and 11 463 controls (men without PrCa). We computed association tests for approximately 2.6 million SNPs and followed up the most significant SNPs by genotyping 49 121 samples in 29 studies through the international PRACTICAL and BPC3 consortia. We not only confirmed the association of a PrCa susceptibility locus, rs11672691 on chromosome 19, but also showed an association with aggressive PrCa [odds ratio = 1.12 (95% confidence interval 1.03-1.21), P = 1.4 × 10(-8)]. This report describes a genetic variant which is associated with aggressive PrCa, which is a type of PrCa associated with a poorer prognosis.

The social construction of prostitution in Californian 'John' Schools

The existence of prostitution in society continues to be a highly contested issue in both political and social arenas. With traditional criminal justice methods to address prostitution focussing predominantly on sex workers, newly formed initiatives have been created to target the demand side of prostitution. ‘John Schools’ – diversionary programs for clients, or ‘johns’ who have been arrested for prostitution offences – aim to educate participants on the various harms and risks associated with such behaviour and claim to provide an innovative means to reduce prostitution by decreasing demand for sexual services. It is evident however, that these programs perpetuate traditional social constructions of prostitution, characterising the act, and the actors, as sexually deviant. This paper examines the curriculum of these programs in order to identify how prostitution is constructed, firstly through the depiction of the victims in the program, and secondly through the characterisation of prostitution offenders. This paper argues that such initiatives merely extend the charge of sexual deviance from the sellers of sex to the buyers, and fail to acknowledge autonomy and choice for sex workers and clients.

The human tissue kallikrein and kallikrein-related peptidase family

The human kallikrein-related peptidases are a subgroup of trypsin and chymotrypsin-like serine peptidases that are characterized by their homology to tissue kallikrein or kallikrein 1 (KLK1) encoded by the KLK1 gene (reviewed in[1-4]). The human KLK locus spans an approximately 320 kb region on chromosome 19q13.3-13.4 and contains fifteen genes encoding KLK1 and fourteen other kallikrein-related peptidases, KLK2-KLK15, which have been named contiguously in the locus in the order of their discovery [5-8] (Figure 606.1). It is the largest contiguous cluster of serine protease encoding genes in the human genome which has evolved from gene duplication of KLK1 and then subsequent reduplication of the newly evolved KLK genes [2]. The high conservation noted for KLK1-KLK3 (62-77%) reflects the proposed duplication of the KLK1 gene that produced the KLK2 gene which further generated the KLK3 gene. In contrast, the newer KLK4-KLK15 proteases share much less similarity, from 24-66%, although strong homology between KLK4 and KLK5, KLK9 and KLK11, and KLK10 and KLK12 suggests these genes are duplications of each other [2]...

Californian 'John Schools' and the social construction of prostitution

Within political and social arenas, prostitution continues to be a highly contested and debated issue. Generally conceptualised as a ‘problem’ in need of eradication, prostitution is strongly linked to immorality and deviance. The methods of addressing this phenomenon have experienced a shift from focusing predominantly on the sex worker, to directly targeting the clients of commercial sex. Such practices have resulted in the creation of policy initiatives such as ‘John Schools’—diversionary programs for clients, or ‘Johns’ who have been arrested for prostitution offences. The programs aim to educate participants on the various harms and risks associated with such behaviour and claim to offer a means to reduce prostitution by targeting the demand for sexual services. It is evident however, that these programs perpetuate traditional social constructions of prostitution, characterising the act, and the actors, as sexually deviant. This paper examines the curriculum of these programs in order to identify how prostitution is constructed—firstly through the depiction of the victims in the program and secondly through the characterisation of prostitution offenders—and argues that such initiatives merely extend the charge of sexual deviance from the sellers of sex to the buyers,whilst failing to acknowledge autonomy and choice for sex workers and clients.

The economics of awards, status and performance: the John Bates Clark Medal and the Fellowship of the Econometric Society

This thesis investigates whether receiving an important award in academia raises recipients’ subsequent research productivity and status compared to a synthetic control group of non-recipient scholars with similar previous research performance. It examines the case of being awarded the John Bates Clark Medal and becoming a Fellow of the Econometric Society finding evidence of positive incentive and status effects that raise both productivity and citation levels.

Directing democracy : competing interests and contested terrain in the John Lewis Partnership

The John Lewis Partnership is one of Europe’s largest models of employee ownership and has been operating a form of employee involvement and participation since its formation in 1929. It is frequently held up as a model of best practice (Cathcart, 2013) and has been described as a ‘workers’ paradise’ (Stummer and Lacey, 2001). At the beginning of 2012, the Deputy Prime Minister of the UK unveiled plans to create a ‘John Lewis Economy’ (Wintour, 2012). As John Lewis is being positioned at the heart of political and media discussions in the UK about alternatives to the corporate capitalist model of enterprise, it is vital that more is known about the experience of employee involvement and participation within the organisation. This article explores the ways in which the practice of employee involvement and participation has changed in John Lewis as a result of competing employee and managerial interests. Its contribution is a contemporary exploration of participation in the John Lewis Partnership and an examination of the ways in which management and employees contested the meaning and practice of employee involvement and participation as part of a ‘democracy project’, which culminated in significant changes and degeneration of the democratic structures.

The John Lewis model reveals the tensions and paradoxes at the heart of workplace democracy

Politicians of all parties have been keen to promote the ‘John Lewis model’ of industrial organisation, emphasising its features of employee ownership and workplace democracy. Dr Abby Cathcart’s research into the company shows that management and workers have different visions of what ‘partnership’ means, with ongoing struggle taking place via the organisation’s democratic structures. This, she argues, has stark implications for other organisations with partnership models that are less robust.

Review : "Ghosts...of the Civil Dead" -- John Hillcoat

Synopsis and review of the Australian prison film Ghosts...of the Civil Dead (John Hillcoat, 1988). Drawing heavily from the book In the Belly of the Beast by American author and long-term prisoner Jack Henry Abbott, as well as from the historical and philosophical work of Michel Foucault (the credits include ‘Foucault Authority – Simon During’), Ghosts… Of the Civil Dead is a searing critique of the so-called ‘new generation’ prison system developed in the United States and recently introduced in Australia. Director John Hillcoat and producer Evan English conducted extensive research for the film, including spending time at the National Institute of Corrections, a think tank in Colorado, and visiting numerous institutions like the ‘new Alcatraz’ at Marion Illinois and other maximum security prisons across the United States. Using a mix of professionals and non-actors, including former prisoners and prison guards, the ‘story’ was workshopped during a lengthy rehearsal period with many actual events and experiences of participants incorporated into the film. The end result deliberately blurs the line between American and Australian prison experience to make the political point that what had happened in the US – from where many events and characters, and much of the architecture and design of the prison are drawn – was beginning to happen in Australia. The film emphasises the vicious cycle of institutionalisation, and highlights the role state authorities play in manufacturing, provoking and manipulating violence and fear both in prisons and in wider society as a means to augment policing and surveillance of the population, to oppress the working classes, and to maintain the political status quo...

Variants in the human potassium channel gene (KCNN3) are associated with migraine in a high risk genetic isolate

The calcium-activated potassium ion channel gene (KCNN3) is located in the vicinity of the familial hemiplegic migraine type 2 locus on chromosome 1q21.3. This gene is expressed in the central nervous system and plays a role in neural excitability. Previous association studies have provided some, although not conclusive, evidence for involvement of this gene in migraine susceptibility. To elucidate KCNN3 involvement in migraine, we performed gene-wide SNP genotyping in a high-risk genetic isolate from Norfolk Island, a population descended from a small number of eighteenth century Isle of Man ‘Bounty Mutineer’ and Tahitian founders. Phenotype information was available for 377 individuals who are related through the single, well-defined Norfolk pedigree (96 were affected: 64 MA, 32 MO). A total of 85 SNPs spanning the KCNN3 gene were genotyped in a sub-sample of 285 related individuals (76 affected), all core members of the extensive Norfolk Island ‘Bounty Mutineer’ genealogy. All genotyping was performed using the Illumina BeadArray platform. The analysis was performed using the statistical program SOLAR v4.0.6 assuming an additive model of allelic effect adjusted for the effects of age and sex. Haplotype analysis was undertaken using the program HAPLOVIEW v4.0. A total of four intronic SNPs in the KCNN3 gene displayed significant association (P < 0.05) with migraine. Two SNPs, rs73532286 and rs6426929, separated by approximately 0.1 kb, displayed complete LD (r 2 = 1.00, D′ = 1.00, D′ 95% CI = 0.96–1.00). In all cases, the minor allele led to a decrease in migraine risk (beta coefficient = 0.286–0.315), suggesting that common gene variants confer an increased risk of migraine in the Norfolk pedigree. This effect may be explained by founder effect in this genetic isolate. This study provides evidence for association of variants in the KCNN3 ion channel gene with migraine susceptibility in the Norfolk genetic isolate with the rarer allelic variants conferring a possible protective role. This the first comprehensive analysis of this potential candidate gene in migraine and also the first study that has utilised the unique Norfolk Island large pedigree isolate to implicate a specific migraine gene. Studies of additional variants in KCNN3 in the Norfolk pedigree are now required (e.g. polyglutamine variants) and further analyses in other population data sets are required to clarify the association of the KCNN3 gene and migraine risk in the general outbred population.

The effects of vitamin supplementation and MTHFR (C677T) genotype on homocysteine-lowering and migraine disability

BACKGROUND: Migraine is a prevalent and debilitating disease that may, in part, arise because of disruption in neurovascular endothelia caused by elevated homocysteine. This study examined the homocysteine-lowering effects of vitamin supplementation on migraine disability, frequency and severity and whether MTHFRC677T genotype influenced treatment response. METHODS: This was a randomized, double-blind placebo, controlled trial of 6 months of daily vitamin supplementation (i.e. 2 mg of folic acid, 25 mg vitamin B6, and 400 microg of vitamin B12) in 52 patients diagnosed with migraine with aura. FINDINGS: Vitamin supplementation reduced homocysteine by 39% (approximately 4 mumol/l) compared with baseline, a reduction that was greater then placebo (P=0.001). Vitamin supplementation also reduced the prevalence of migraine disability from 60% at baseline to 30% after 6 months (P=0.01), whereas no reduction was observed for the placebo group (P>0.1). Headache frequency and pain severity were also reduced (P<0.05), whereas there was no reduction in the placebo group (P>0.1). In this patient group the treatment effect on both homocysteine levels and migraine disability was associated with MTHFRC677T genotype whereby carriers of the C allele experienced a greater response compared with TT genotypes (P<0.05). INTERPRETATION: This study provides some early evidence that lowering homocysteine through vitamin supplementation reduces migraine disability in a subgroup of patients. Larger trials are now warranted to establish whether vitamin therapy is a safe, inexpensive and effective prophylactic option for treatment of migraine and whether efficacy is dependant on MTHFRC677T genotype.

Phenotypical characterisation of the isolated Norfolk Island population focusing on epidemiological indicators of cardiovascular disease

Objectives Only 193 people from Pitcairn Island, all descended from 9 ‘Bounty’ mutineers and 12 Tahitian women, moved to the uninhabited Norfolk Island in 1856. Our objective was to assess the population of Norfolk Island, several thousand km off the eastern coast of Australia, as a genetic isolate of potential use for cardiovascular disease (CVD) gene mapping. Methods A total of 602 participants, approximately two thirds of the island’s present adult population, were characterized for a panel of CVD risk factors. Statistical power and heritability were calculated. Results Norfolk Islander’s possess an increased prevalence of hypertension, obesity and multiple CVD risk factors when compared to outbred Caucasian populations. 64% of the study participants were descendents of the island’s original founder population. Triglycerides, cholesterol, and blood pressures all had heritabilities above 0.2. Conclusions The Norfolk land population is a potentially useful genetic isolate for gene mapping studies aimed at identifying CVD risk factor quantitative trait loci (QTL).

Clinically-indicated replacement versus routine replacement of peripheral venous catheters

BACKGROUND: US Centers for Disease Control guidelines recommend replacement of peripheral intravenous (IV) catheters no more frequently than every 72 to 96 hours. Routine replacement is thought to reduce the risk of phlebitis and bloodstream infection. Catheter insertion is an unpleasant experience for patients and replacement may be unnecessary if the catheter remains functional and there are no signs of inflammation. Costs associated with routine replacement may be considerable. This is an update of a review first published in 2010. OBJECTIVES: To assess the effects of removing peripheral IV catheters when clinically indicated compared with removing and re-siting the catheter routinely. SEARCH METHODS: For this update the Cochrane Peripheral Vascular Diseases (PVD) Group Trials Search Co-ordinator searched the PVD Specialised Register (December 2012) and CENTRAL (2012, Issue 11). We also searched MEDLINE (last searched October 2012) and clinical trials registries. SELECTION CRITERIA: Randomised controlled trials that compared routine removal of peripheral IV catheters with removal only when clinically indicated in hospitalised or community dwelling patients receiving continuous or intermittent infusions. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. MAIN RESULTS: Seven trials with a total of 4895 patients were included in the review. Catheter-related bloodstream infection (CRBSI) was assessed in five trials (4806 patients). There was no significant between group difference in the CRBSI rate (clinically-indicated 1/2365; routine change 2/2441). The risk ratio (RR) was 0.61 but the confidence interval (CI) was wide, creating uncertainty around the estimate (95% CI 0.08 to 4.68; P = 0.64). No difference in phlebitis rates was found whether catheters were changed according to clinical indications or routinely (clinically-indicated 186/2365; 3-day change 166/2441; RR 1.14, 95% CI 0.93 to 1.39). This result was unaffected by whether infusion through the catheter was continuous or intermittent. We also analysed the data by number of device days and again no differences between groups were observed (RR 1.03, 95% CI 0.84 to 1.27; P = 0.75). One trial assessed all-cause bloodstream infection. There was no difference in this outcome between the two groups (clinically-indicated 4/1593 (0.02%); routine change 9/1690 (0.05%); P = 0.21). Cannulation costs were lower by approximately AUD 7.00 in the clinically-indicated group (mean difference (MD) -6.96, 95% CI -9.05 to -4.86; P ≤ 0.00001). AUTHORS' CONCLUSIONS: The review found no evidence to support changing catheters every 72 to 96 hours. Consequently, healthcare organisations may consider changing to a policy whereby catheters are changed only if clinically indicated. This would provide significant cost savings and would spare patients the unnecessary pain of routine re-sites in the absence of clinical indications. To minimise peripheral catheter-related complications, the insertion site should be inspected at each shift change and the catheter removed if signs of inflammation, infiltration, or blockage are present.
