Occupational exposure to inhaled nanoparticles: Are young workers being left in the dust?

Occupational exposure to inhaled nanoparticles (NPs) represents a significant concern for worker health. Adolescent workers may face unique risks for exposure and resulting health effects when compared with adult workers. This manuscript discusses key differences in risks for occupational exposures to inhaled NPs and resulting health effects between young workers and adult workers via an examination of both physiological and occupational setting factors. Previous studies document how adolescents often face distinct and unique exposure scenarios to occupational hazards when compared to adults. Moreover, they also face different and unpredictable health effects because biological functions such as detoxification pathways and neurological mechanisms are still developing well into late adolescence. Early exposure also increases the chances of developing long-latency disease earlier in life. Taken together, adolescents' rapid growth and development encompasses highly dynamic and complex processes. An aggravating factor is that these processes do not necessarily fall in line with legal classifications of adulthood, nor with occupational exposure limits created for adult workers. The differences in exposures and health consequences from NPs on young workers are insufficiently understood. Research is needed to better understand what adolescent-specific mitigation strategies may be most suitable to address these risk factors

Occupational safety and health management in developing countries: A study of construction companies in Malawi

Purpose: Whilst occupational safety and health (OSH) management is recognised as an important mechanism for addressing poor OSH performance, limited empirical insight is available on OSH management by construction companies in sub-Saharan Africa. This study investigated OSH management by construction companies (i.e. contractors) in Malawi in order to unpick implementation issues that need attention. Materials and methods: 46 OSH management practices were probed through a survey of contractors. Results: Implementation of OSH practices amongst contractors is low, particularly for practices related to the policy, organising, measuring and reviewing, and auditing elements of OSH management. Company size, is associated with implementation of nearly a half of the 46 OSH practices. Certification of company to Standard No. OHSAS 1800:2007 is associated with the implementation of fewer practices. Conclusions: OSH management improvement efforts would need to focus on the elements with particularly low implementation of practices as well as include initiatives that focus on helping micro enterprises to improve their OSH management. Association between business characteristics and OSH management may be more evident with certain elements such as the organising element. Furthermore, certification to Standard No. OHSAS 1800:2007 may not necessarily translate into greater implementation of OSH management practices, especially in developing countries

States and the political economy of unfree labour

A growing body of academic and policy research seeks to understand and address the problem of contemporary unfree labour. In this article, we argue that this literature could be strengthened by a stronger conceptualization of, and more systematic attention towards, the role of national states. In particular, we argue that there is a need to move beyond simplistic conceptualisations of states as simple agents of regulation and criminal justice enforcement who respond to the problem of unfree labour, and to recognize the causal and multifaceted role that national states play in creating the conditions in which unfree labour can flourish. We propose a framework to understand and compare the ways in which national states shape the political economy of unfree labour. Focusing on the United States, we outline three arenas of governance in which national states have been particularly central to enabling the conditions for unfree labour: the regulation of labour mobility, labour market regulation, and business regulation. We conclude by reflecting on the comparative political economy research that will be required to understand the role of different states in shaping the conditions in which unfree labour thrives or is eliminated

Trials and tribulations : the 'use' (and 'misuse') of evidence in public policy

Randomized controlled trials (RCTs) are increasingly playing a central role in shaping policy for development. By comparison, social experimentation has not driven the great transformation of welfare within the developed world. This introduces a range of issues for those interested in the nature of research evidence for making policy. In this article we will seek a greater understanding of why the RCT is increasingly seen as the ‘gold standard’ for policy experiments in low- and middle-income countries (LMICs), but not in the more advanced liberal democracies, and we will explore the implications of this. One objection to the use of RCTs, however can be cost, but implementing policies and programmes without good evidence or a good understanding of their effectiveness is unlikely to be a good use of resources either. Other issues arise. Trials are often complex to run and ethical concerns often arise in social ‘experiments’ with human subjects. However, rolling out untested policies may also be morally objectionable. This article sheds new light on the relationship between evidence and evaluation in public policy in both the global north and developing south. It also tackles emerging issues concerning the ‘use’ and ‘misuse’ of evidence and evaluation within public policy

Patrilineality, Son Preference, and Sex Selection in South Korea and Vietnam

Recent advances in promoting the rights of women and girls globally have been partially offset by increasing implementation of son preference through offspring sex selection, leading to rising sex ratios at birth1 (SRB) and child sex ratios throughout Asia, as well as parts of Eastern Europe and Africa. The past two decades have seen the number of countries with high child sex ratios increase from five to nineteen (Hudson and den Boer 2015). In recent history, only one country has reduced its sex ratio at birth from extremely high levels to biologically normal levels: South Korea, from a peak of 116.5 males per 100 females in 1990 to 106.2 in 2007. While South Korea's sex ratio at birth was declining throughout the early to mid 2000s, the sex ratio at birth in another Asian country, Vietnam, began an erratic rise, reaching 113.8 in 2013 (see Figure 1). How can we explain this recent rise in Vietnam's sex ratio, and are there lessons for Vietnam, or for other countries facing high sex ratios at birth, from the experience of South Korea
