    Seminario InternacionalEl marco jurĂ­dico en relaciĂłn al uso recreativo y mĂ©dico del cannabis varĂ­a mucho segĂșn el paĂ­s y la regiĂłn, pero sigue estando prohibido en gran medida a nivel internacional. Los defensores a favor de medidas regulativas, han enfatizado el potencial para erradicar el mercado negro del cannabis, mejorar el control de su calidad, aumentar los ingresos fiscales, mejorar la disponibilidad de cannabis medicinal y reducir la violencia relacionada con las pandillas y carteles que trafican con drogas.1.

    The Role of Scientific Source Credibility and Goodwill in Public Skepticism Toward GM Foods

    The complex web of political-economic relations that constitutes biotechnology coupled with a contentious history of public resistance, illustrates the power of perceptions of credibility in mediating individuals’ judgements about GMOs. To more accurately measure what contributes to public skepticism of GM foods, the present research applies a multidimensional model of source credibility comprised of scientific understanding, integrity, agreement, concern, trust, and goodwill (bias). Testing the Anti-Reflexivity Thesis in a new context, we also explore the role of attitudes about science and economic innovation by analyzing associations between political ideology and beliefs about the potential impacts of GM foods. Using data from the Pew Research Center’s American Trends Panel, we find evidence of politically polarized perceptions of GM scientists’ credibility and public beliefs about the environmental risks and benefits of GM foods. Results suggest that political ideology is indirectly associated with beliefs about GM impacts on the food supply, largely through perceptions of goodwill, the so-called “lost” dimension of source credibility. Because demand for biotechnology products like gene edited foods is expected to increase, consumer beliefs about GMOs will likely have significant implications for the future of the bioeconomy

    Dietary Iron bioavailability: A simple model that can be used to derive country-specific dietary reference values for adult men and women

    Background: Reference intakes for iron are derived from physiological requirements, with an assumed value for dietary iron absorption. A new approach to estimate iron bioavailability, calculated from iron intake, status, and requirements was used to set European dietary reference values, but the values obtained cannot be used for low- and middle-income countries where diets are very different. Objective: We aimed to test the feasibility of using the model developed from United Kingdom and Irish data to derive a value for dietary iron bioavailability in an African country, using data collected from women of child-bearing age in Benin. We also compared the effect of using estimates of iron losses made in the 1960s with more recent data for whole body iron losses. Methods: Dietary iron intake and serum ferritin (SF), together with physiological requirements of iron, were entered into the predictive model to estimate percentage iron absorption from the diet at different levels of iron status. Results: The results obtained from the 2 different methods for calculating physiological iron requirements were similar, except at low SF concentrations. At a SF value of 30 ”g/L predicted iron absorption from the African maize-based diet was 6%, compared with 18% from a Western diet, and it remained low until the SF fell below 25 ”g/L. Conclusions: We used the model to estimate percentage dietary iron absorption in 30 Beninese women. The predicted values agreed with results from earlier single meal isotope studies; therefore, we conclude that the model has potential for estimating dietary iron bioavailability in men and nonpregnant women consuming different diets in other countries

    Differences in use of electronic nicotine delivery systems by smoking status and demographic characteristics among Australian young adults

    Issue addressed: Electronic nicotine delivery systems (ENDS) continue to grow in popularity, particularly among young adults. Understanding by whom various ENDS are being used and why within this population segment can assist the development of appropriate interventions targeting those most vulnerable to use and inform policy decisions in this area. Accordingly, this study assessed the demographic characteristics associated with ENDS use among Australian young adults, and reasons for current e-cigarette use. Methods: An online survey was administered to 1116 Australians aged 18-25 years (59% female). Results: Smokers were more likely than non-smokers to report (a) ever use of ENDS (67% vs 28%), (b) ever use of an e-cigarette (64% vs 24%), e-cigar (17% vs 8%) or e-hookah (15% vs 8%) and (c) current use of e-cigarettes (19% vs 6%). Male smokers were more likely than female smokers to be current e-cigarette users. The most common reason for current e-cigarette use was enjoyment. Conclusions: Young male adults appear to be particularly vulnerable to becoming regular e-cigarette users. This demographic group may need to be a primary focus of prevention and intervention efforts. Contrary to popular belief, smoking cessation was not a primary reason for e-cigarette use. So what?: Greater efforts are needed to educate young adults on the harms associated with ENDS use, especially if use is being driven by the perception that they are a harmless means of amusement. Maintaining existing regulations limiting the accessibility of these products is crucial to ensuring widespread use is minimised
