Epigenetics and migraine; complex mitochondrial interactions contributing to disease susceptibility

Migraine is a common neurological disorder classified by the World Health Organisation (WHO) as one of the top twenty most debilitating diseases in the developed world. Current therapies are only effective for a proportion of sufferers and new therapeutic targets are desperately needed to alleviate this burden. Recently the role of epigenetics in the development of many complex diseases including migraine has become an emerging topic. By understanding the importance of acetylation, methylation and other epigenetic modifications, it then follows that this modification process is a potential target to manipulate epigenetic status with the goal of treating disease. Bisulphite sequencing and methylated DNA immunoprecipitation have been used to demonstrate the presence of methylated cytosines in the human D-loop of mitochondrial DNA (mtDNA), proving that the mitochondrial genome is methylated. For the first time, it has been shown that there is a difference in mtDNA epigenetic status between healthy controls and those with disease, especially for neurodegenerative and age related conditions. Given co-morbidities with migraine and the suggestive link between mitochondrial dysfunction and the lowered threshold for triggering a migraine attack, mitochondrial methylation may be a new avenue to pursue. Creative thinking and new approaches are needed to solve complex problems and a systems biology approach, where multiple layers of information are integrated is becoming more important in complex disease modelling.

Exploring the re-criminalising of OHS breaches in the context of industrial death

Since the 1980s the calls for further criminalisation of organisational conduct causing harm to workers, the public and the environment have intensified in Australia, Canada and England and Wales.' One focal point of this movement has been the criminal law's response to organisations (and their personnel) failing to comply with occupational health and safety ('OHS') standards, particularly when physical harm (death and serious injury) has resulted from those breaches. Some governments have responded with proposals to enable manslaughter prosecutions to be initiated 'more effectively' against organisations causing the deaths of workers or, in some cases, members of the public (Archibald et al, 2004; Haines and Hall, 2004; Hall et al, 2004; Tombs and Whyte, 2003). In Australia governments have also increased monetary penalties for regulatory OHS offences, a few have introduced other contemporary organisational sanctions, and some have initiated OHS prosecutions more vigorously and with larger fines.

OHS inspectors and psychosocial risk factors: Evidence from Australia

Legislation giving prominence to psychosocial risk factors at work has changed the role of government occupational health and safety (OHS) inspectors in many countries. Yet little is known about how inspectorates have responded to these changes. Between 2003 and 2007 an Australian study was undertaken on OHS standards, entailing detailed documentary analysis, interviews with 36 inspectorate managers and 89 inspectors, and observations made when researchers accompanied inspectors on 120 typical workplace visits. Our study found that general duty provisions in OHS legislation clearly incorporated psychosocial hazards and inspectorates had introduced guidance material, pursued campaigns and increased interventions in this area. However, the regulatory framework remained narrow (focused on bullying/harassment, occupational violence and work stress) and workplace visits revealed psychosocial hazards as a marginal area of inspectorate activity. These findings were reinforced in interviews. While aware of psychosocial hazards inspectors often saw the issue as problematic due to limited training, resourcing constraints, deficiencies in regulation and fears of victimisation amongst workers. In order to address these problems a number of changes are required that recognize the distinctiveness of psychosocial hazards including their ‘invisibility’. Notable here are revisions to regulation (both general duty provisions and specific codes), the development of comprehensive guidance and assessment tools to be used by inspectors, greater use of procedural enforcement, and enhanced inspectorate resourcing and training. There is also a need to recognize complex inter-linkages between psychosocial hazards and the industrial relations context.

The implications of de‐collectivist industrial relations laws and associated developments for worker health and safety in Australia, 1996–2007

The institutional and regulatory interlinkages between industrial relations (IR) and occupational health and safety (OHS) are seldom explored in the IR literature. This article begins to address this gap by examining regulatory initiatives in Australia during a period of neoliberal government. It examines the laws enacted by the federal government during this period and events and cases arising from these laws that go some way to illustrating their effects. Evidence is also drawn from detailed research on a number of state OHS inspectorates between 2004 and 2006. It is argued that de-collectivist changes to IR laws exacerbated problems posed by the growth of flexible work arrangements and a drop in union density, weakening participatory provisions in OHS laws and promoting work arrangements that undermined OHS standards. The study provides evidence of the implications of a divergence in the trajectory of IR and OHS laws and the importance of better integrating worker protection laws.

Synonymization of key pest species within the Bactrocera dorsalis species complex (Diptera: Tephritidae): Taxonomic changes based on a review of 20 years of integrative morphological, molecular, cytogenetic, behavioural and chemoecological data

Bactrocera papayae Drew & Hancock, Bactrocera philippinensis Drew & Hancock, Bactrocera carambolae Drew & Hancock, and Bactrocera invadens Drew, Tsuruta & White are four horticultural pest tephritid fruit fly species that are highly similar, morphologically and genetically, to the destructive pest, the Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). This similarity has rendered the discovery of reliable diagnostic characters problematic, which, in view of the economic importance of these taxa and the international trade implications, has resulted in ongoing difficulties for many areas of plant protection and food security. Consequently, a major international collaborative and integrated multidisciplinary research effort was initiated in 2009 to build upon existing literature with the specific aim of resolving biological species limits among B. papayae, B. philippinensis, B. carambolae, B. invadens and B. dorsalis to overcome constraints to pest management and international trade. Bactrocera philippinensis has recently been synonymized with B. papayae as a result of this initiative and this review corroborates that finding; however, the other names remain in use. While consistent characters have been found to reliably distinguish B. carambolae from B. dorsalis, B. invadens and B. papayae, no such characters have been found to differentiate the latter three putative species. We conclude that B. carambolae is a valid species and that the remaining taxa, B. dorsalis, B. invadens and B. papayae, represent the same species. Thus, we consider B. dorsalis (Hendel) as the senior synonym of B. papayae Drew and Hancock syn.n. and B. invadens Drew, Tsuruta & White syn.n. A redescription of B. dorsalis is provided. Given the agricultural importance of B. dorsalis, this taxonomic decision will have significant global plant biosecurity implications, affecting pest management, quarantine, international trade, postharvest treatment and basic research. Throughout the paper, we emphasize the value of independent and multidisciplinary tools in delimiting species, particularly in complicated cases involving morphologically cryptic taxa.

Nonprofit Service Delivery for Government : Accountability Relationships and Mechanisms

When government purchases social services under contract from a nonprofit organisation, a clear accountability relationship is created. The NPO must give an account for the use of the funds and achievement of outcomes to the funder. This paper explores how accountability is enacted in two different types of funding relationships in Queensland. Support is found for the argument that different relationships have different approaches to accountability.

Patterns of boardroom discussions around the accountability process in a nonprofit organisation

This chapter sets out to identify patterns at play in boardroom discussions around the design and adoption of an accountability system in a nonprofit organisation. To this end, it contributes to the scarce literature showing the backstage of management accounting systems (Berry, 2005), investment policy determining (Kreander, Beattie & McPhail, 2009; Kreander, McPhail & Molyneaux, 2004) and financial planning strategizing (Parker, 2004) or budgeting (Irvine 2005). The paucity of publications is due to issues raised by confidentiality preventing attendance at those meetings (Irvine, 2003), Irvine & Gaffikin, 2006). However, often, the implementation of a new control technology occurs over a long period of time that might exceed the duration of a research project (Quattrone & Hopper, 2001, 2005). Recent trends consisting of having research funded by grants from private institutions or charities have tended to reduce the length of such undertakings to a few months or rarely more than a couple of years (Parker, 2013);

Reason of state and a new notion of fortune : Historicising the risk society

Since the 1980s the concept of risk has produced a large and diverse volume of sociological research. Ulrich Beck’s groundbreaking risk society thesis provides a particularly engaging contribution, since it seems that nearly every sociological account of risk engages with this work. For Beck, we are living in second modernity – a new epoch that breaks with pre-modernity and industrial society due to the centrality, incalculability and reflexivity of globalised risk. While Beck’s theory is compelling, a reading of other theorists such as Foucault (2007[1978]) and Hacking (1975,1990) suggests that a difficulty with Beck’s work is that in attempting to explain what is novel about risk in contemporary times, he too quickly passes over the complexities and ruptures of historical change that impact on the history and contingency of risk. This paper begins by presenting a brief analysis of the present state of risk by introducing Beck’s historical narrative of risk from pre-modernity to the risk society; it then outlines the challenges with the “risk as epoch” argument by considering a range of literature, which suggests risk has a more complex history than proposed by Beck; and finally it highlights the value in examining strategies of statecraft in early modern Europe, specifically Machiavelli’s The Prince (2008[1513]) and Giovanni Botero’s political treatise, Della Ragion di Stato (1956[1589]) – as a means of more thoroughly understanding how our current concept of risk emerges. In doing so, this paper seeks to open up new trajectories in the historicisation of risk for other interested scholars.

Investigating tween children's capacity to conceptualise the complex issue of wellbeing

Wellbeing is an area that has gained increased global focus, particularly when considering children’s lives. With the growing focus on children’s wellbeing, it is apparent that this is an important aspect that is being considered in the policy and provision designed for children. The decision-making surrounding wellbeing provision for children typically occurs without the direct input of the children that these services are designed to benefit. With the children’s capacities being variably considered in wider society, opportunities for children to participate in decision-making on matters that affect them are often limited. The absence of children’s perspectives on matters that affect their lives, such as wellbeing, reveal that adults may be missing a key perspective when seeking to understand and cater for children’s wellbeing needs. This article outlines the results of a study that investigated how children aged 8 to 12 years o age (tweens) defined and conceptualised wellbeing. This article proposes that children can be included in the conceptualisation and development of policy and provision designed to benefit them and argues for increased presence of the voice and participation of children in wider societal initiatives.
