Over Time

The demand for Indonesian opah fish as an export product is increasing in the international market. Three countries (Malaysia, Mauritius, and Taiwan) recorded as the leading export destination of Indonesian opah fish. However, as the fish kept in a frozen state during export transportation, the endogenous formaldehyde may increase over time. This research presented the health risk assessment of population in the leading export destination countries that consumed opah fish from Indonesia. The study aimed to reveal the most potential export destination country that may accept an increasing volume of opah fish supply from Indonesia. The potency was determined from current export volume, the amount of endogenous formaldehyde content, and fish consumption at each country. The data were calculated with @Risk®7.0 software. The results showed opah fish consumed by Malaysian can be categorized as safe. Increasing the number of opah fish imported by Malaysian as much as six times, 12 times, 18 times, 27 and 36 times relatively does not cause health risks related to the presence of its endogenous formaldehyde. Moreover, opah fish consumed by Taiwanese is also safe, but with increasing the number of consumptions by more than 26 times is suspected to be potentially causing a health problem. However, opah fish consumed in Mauritius was categorized as unsafe and potentially caused health risks. Based on these results, Indonesia may consider to increase the opah fish export to Malaysia and Taiwan in the future.

ObjectivesTo identify proponents and opponents of the commercialisation and marketing of e-cigarettes and heated tobacco products (HTPs), identify the arguments used on both sides and compare how the arguments have changed over time, we analysed three policy discussions occurring in 2009, 2018 and 2019.MethodsWe conducted a content analysis of one document and six videos from these discussions, provided on the Brazilian Health Regulatory Agency website, or upon request.ResultsThe arguments most used by tobacco companies were related to claims that the use of e-cigarettes and HTPs is less harmful than conventional tobacco. Unions that support its commercialisation also argued that lifting the ban would prevent smuggling and guarantee their quality. On the other side, universities, medical and anti-tobacco institutions argued that such devices may have health risks, including the risk of inducing cigarette smoking. In 2009, most arguments belonged to the ‘health’ theme, while in 2018 and 2019 economic arguments and those related to morals and ethics were frequently used.ConclusionsThose that supported the commercialisation and marketing of e-cigarettes and HTPs first focused on arguments of harm reduction, while 10 years later the right to access and potential economic consequences also became common. Public health agents and academics must gather evidence to effectively respond to these arguments and discuss these policies, and must prepare themselves to use and respond to arguments related to moral and economic themes.

Spatial Feature

Dasymetric mapping of high-resolution population facilitates the exploration of urban spatial feature. While most relevant studies are still challenged by weak spatial heterogeneity of ancillary data and quality of traditional census data, usually outdated, costly and inaccurate, this paper focuses on mobile phone data, which can be real-time and precise, and also strengthens spatial heterogeneity by its massive mobile phone base stations. However, user population recorded by mobile phone base stations have no fixed spatial boundary, and base stations often disperse in extremely uneven spatial distribution, this study defines a distance-decay supply–demand relation between mobile phone user population of gridded base station and its surrounding land patches, and outlines a dasymetric mapping method integrating two-step floating catchment area method (2SFCAe) and land use regression (LUR). The results indicate that LUR-2SFCAe method shows a high fitness of regression, provides population mapping at a finer scale and helps identify urban centrality and employment subcenters with detailed worktime and non-worktime populations. The work involving studies of dasymetric mapping based on LUR-2SFCAe method and mobile phone data proves to be encouraging, sheds light on the relationship between mobile phone users and nearby land use, brings about an integrated exploration of 2SFCAe in LUR with distance-decay effect and enhances spatial heterogeneity.
