The Commercial Determinants of Violence: Identifying Opportunities for Violence Prevention through a Public Health-Based Framework Analysis.

Violence has immediate and long-term repercussions for the health of individuals and communities. Recent increases in the understanding of public health approaches to violence prevention have focused on the policies and practices of government, health, and other public sector agencies. However, the roles of commercial bodies in fostering and preventing violence remain largely unaddressed. The wealth and influence of some companies now exceeds that of many countries. Consequently, it is timely to explore the roles of commercial processes in violence. Using a conceptual framework for the commercial determinants of health, we examine seven practices: political; scientific; marketing; supply chain and waste; labor and employment; financial; and reputational management. We include areas directly linked with violence (e.g., firearms) and those that indirectly impact violence through the following: design and promotion of products; employment practices; and impacts on environment, poverty, and local resources. A range of avoidable commercial behaviors are found to increase levels of violence including the following: lobbying practices; distortion of scientific processes; polluting manufacture and supply lines; poor employee protections; financial investment in organizations and regimes associated with violence; and misleading communications and marketing. We conclude commercial actors can take action to ensure their workers, clients, suppliers, and distributors help prevent, not promote, violence. New technologies such as artificial intelligence are transforming corporate processes and products and offer opportunities to implement violence prevention through commercial developments (e.g., monitoring online content). International regulation of commercial behaviors is needed to prevent interpersonal and interstate conflict and harms to health and trade.

Describing Patterns of Known Domestic Abuse Among Different Ethnic Groups.

Domestic abuse perpetration remains a major threat to public health, safety and wellbeing, causing serious harms and contributing significantly to overall crime globally. In the United Kingdom, research links the crime type to high economic and social costs. In the last 10 years, our collective knowledge of domestic abuse has grown in conjunction with its prioritisation in government policy. Several innovative studies have built a picture of the most serious cases and overall patterns of abuse but to date, examination of these trends by ethnic groups has been limited despite increasing attention to disproportionality in racially minoritised communities in criminal justice system outcomes. In this article we aimed to address this issue through the analysis of 150,000 domestic abuse records kept by police forces in England. Using descriptive statistics, we examined the relative distributions of different ethnicities by suspected offending rate, investigative outcome and crime harm. We found two patterns of note: firstly, that suspects from several categories of minoritized communities are consistently over-represented compared to the White British population among most harmful cases, and secondly, that in Asian communities, offences are less frequently "solved." We discuss the implications for future research and practice.

Investigating determinants of catastrophic health spending among poorly insured elderly households in urban Nigeria.

BACKGROUND: In the absence of functional social security mechanisms for elderly people in Nigeria, elderly households are solely responsible for geriatric healthcare costs, which can lead to catastrophic health expenditures (CHE) - particularly among the poor. This study investigates the key determinants of CHE among poorly insured elderly households in Nigeria. We also offer some policy options for reducing the risk of CHE. METHODS: Data on out-of pocket payments and self-reported health status were sourced from the Nigerian General Household Panel Survey (NGHPS) in Nigeria, conducted by the National Bureau of Statistics in 2010, with technical support from the World Bank. CHE was defined at the 10% of total consumption expenditure threshold. The determinants of CHE and their marginal effects were investigated using probit regressions. An elderly household is defined as a household with at least one elderly member ≥ 50 years old. RESULTS: The proportion of elderly households with CHE is 9.6%. Poorer and smaller elderly households were most at risk of CHE. Female-headed households were less likely to incur CHE compared to male-headed households (p < 0.01). Conversely, households with informal health financing arrangements were less likely to incur CHE (p < 0.001). Education and utilising a health promoting tool, such as treated bednets increased the probability of incurring CHE in Urban Nigeria. CONCLUSION: Findings from this paper should prompt policy action to financially support poor elderly households at risk of CHE in Urban Nigeria. The Nigerian government should enhance the national health insurance scheme to provide better coverage for elderly people, thereby protecting elderly households from incurring CHE.

Methane storage in molecular nanostructures.

We survey various molecular structures which have been proposed as possible nanocontainers for methane storage. These are molecular structures that have been investigated through either experiments, molecular dynamics simulations or mathematical modelling. Computational simulation and mathematical modelling play an important role in predicting and verifying experimental outcomes, but both have their limitations. Even though recent advances have greatly improved computations, due to the large number of atoms and force field calculations involved, computational simulations can still be time consuming as compared to an instantaneous mathematical modelling approach. On the other hand, underlying an ideal mathematical model, there are many assumptions and approximations, but such modelling often reveals the key physical parameters and optimal configurations. Here, we review methane adsorption for three conventional nanostructures, namely graphite, single and multi-walled carbon nanotubes, and nanotube bundles (including interstitial and groove sites), and we survey methane adsorption in other molecular structures including metal organic frameworks. We also include an examination of minimum binding energies, equilibrium distances, gravimetric and volumetric uptakes, volume available for adsorption, as well as the effects of temperature and pressure on the adsorption of methane onto these molecular structures.
