Policy and prevention approaches for disordered and hazardous gaming and internet use: an international perspective

Problems related to high levels of gaming and Internet usage are increasingly recognized as a potential public health burden across the developed world. The aim of this review was to present an international perspective on prevention strategies for Internet gaming disorder and related health conditions (e.g., Internet addiction), as well as hazardous gaming and Internet use. A systematic review of quantitative research evidence was conducted, followed by a search of governmental reports, policy and position statements, and health guidelines in the last decade. The regional scope included the United States, United Kingdom, Australia, China, Germany, Japan, and South Korea. Prevention studies have mainly involved school-based programs to train healthier Internet use habits in adolescents. The efficacy of selective prevention is promising but warrants further empirical attention. On an international scale, the formal recognition of gaming or Internet use as a disorder or as having quantifiable harms at certain levels of usage has been foundational to developing structured prevention responses. The South Korean model, in particular, is an exemplar of a coordinated response to a public health threat, with extensive government initiatives and long-term strategic plans at all three levels of prevention (i.e., universal, selective, and indicated). Western regions, by comparison, are dominated by prevention approaches led by non-profit organizations and private enterprise. The future of prevention of gaming and Internet problems ultimately relies upon all stakeholders working collaboratively in the public interest, confronting the reality of the evidence base and developing practical, ethical, and sustainable countermeasures

Food for life: An exploration of context, methodology and research impact of a complex programme evaluation

This thesis involves the submission of published academic work with a critical commentary, in accordance with the regulations of UWE for DPhil degrees. Fourteen papers are submitted, published between 2008 and 2017. These include nine peer reviewed journal articles, one book chapter section and three externally reviewed research reports. These works share a common concern with the intersections between food, public health and sustainability, and the majority draw upon evaluation research on the Food for Life programme conducted from 2007 to 2016. I argue in the critical commentary that these works represent cumulative body of academic conceptual and empirical enquiry on the development, implementation and impacts of a complex community-based initiative. Broadly following a chronology, I examine the context, methodological and substantive themes that link the published works and how these developed over the course of time. In doing so I demonstrate how the thesis addresses UWE’s doctoral descriptors in terms of originality, significance, methodological understanding and critical application in the context of a major programme of evaluation. I include an account of my personal intellectual contribution to the research and associated publications. My commentary then sets out and reflects on the impact of the published works in academic, service and policy arenas. I consider the widespread effects of the research and some challenges involved in creating an account of impact. In the conclusion, I draw out some overarching methodological concerns on the tensions between idealism and pragmatism; the balance between integrative and eclectic narratives and the value of an iterative approach towards the evaluative research on complex community based programmes. Finally, I summarise how the DPhil works contribute towards our understanding of how whole settings-based programmes can create food system change through offering a conceptual, practical and dialogical synergy for action

Late lessons from early warnings: science, precaution, innovation

'There was a strange stillness. The birds for example — where had they gone? Many people spoke about them, puzzled and disturbed. The feeding stations in the backyards were deserted. The few birds seen anywhere were moribund: they trembled violently and could not fly. It was a spring without voices ... only silence lay over the fields and woods and marsh.' The book Silent Spring by Rachel Carson is mainly about the impacts of chemicals (in particular in particular dichlorodiphenyltrichlorethane also known as DDT) on the environment and human health. Indeed, the close association between humans and birds remains very apt. Representing the only two warm-blooded groups of life on Earth, mammals and birds share the same environments and threats. Carson's claim that she lived in 'an era dominated by industry, in which the right to make a dollar at whatever cost is seldom challenged' still resonates strongly with the problems that societies face all over the world. One chapter heading, 'The obligation to endure', derived from the French biologist and philosopher Jean Rostand's famous observation that, 'the obligation to endure gives us the right to know'. United States President John F. Kennedy responded to the challenge posed by Carson by investigating DDT, leading to its complete ban in the US. The ban was followed by a range of institutions and regulations concerned with environmental issues in the US and elsewhere, driven by public demand for knowledge and protection. DDT was the primary tool used in the first global malaria eradication programme during the 1950s and 1960s. The insecticide is sprayed on the inner walls and ceilings of houses. Malaria has been successfully eliminated from many regions but remains endemic in large parts of the world. DDT remains one of the 12 insecticides — and the only organochlorine compound — currently recommended by the World Health Organization (WHO), and under the Stockholm Convention on Persistent Organic Pollutants, countries may continue to use DDT. Global annual use of DDT for disease vector control is estimated at more than 5 000 tonnes. It is clear that the social conscience awakened by Rachel Carson 50 years ago gave momentum to a groundswell of actions and interventions that are slowly but steadily making inroads at myriad levels. Chapter 17 of her book, 'The other road' reminds the reader of the opportunities that should have been seized much earlier. With more than 10 % of bird species worldwide now threatened in one way or another, it is clear that we missed early warnings or failed to act on them. Will we continue to miss signposts to 'other roads'? Are our obligations to endure met by our rights to know? As Carson said 50 years ago: 'The choice, after all, is ours to make.
