Policy Advice to Alberta’s New Premier

On September 6th, 2014, members of the Progressive Conservative Party of Alberta elected Jim Prentice as leader of their party, and Premier of Alberta.The School of Public Policy assembled its key thinkers in economic, taxation, energy and natural resource policy to provide unsolicited but important advice to Premier Prentice on some areas of policy that matter most to Alberta, and that will demand the Premier’s attention as he takes office.These are opinion pieces, are not peer reviewed, and reflect the views of their authors alone

Holy anorexia: Eating disorders symptomatology and religiosity among Muslim women in the United Arab Emirates

© 2017 Elsevier B.V. There is a substantial body of literature reporting a negative association between religiosity and psychiatric symptoms. In the context of eating disorders, however, this relationship appears to be reversed. The few studies exploring the relationship between religiosity and eating disorders have mostly focused on the Judeo-Christian religious traditions in Western nations. The present study examines this relationship among Muslim college women from the United Arab Emirates (UAE). All participants (N = 1069) independently completed the religious commitment inventory (RCI-10) and the eating attitudes test (EAT-26). As hypothesised, there was a positive association between religiosity and eating disorders symptoms. Furthermore, those scoring above the EAT-26 cut-off reported significantly greater levels of religiosity. These findings suggest that heightened religiosity among young Emirati women may represent a vulnerability factor for eating disorders. Preventative initiatives in the UAE should consider focusing on religiosity

Evapotranspiration model comparison and an estimate of field scale Miscanthus canopy precipitation interception

The bioenergy crop Miscanthus x giganteus has a high water demand to quickly increase biomass with rapid canopy closure and effective rainfall interception, traits that are likely to impact on hydrology in land use change. Evapotranspiration (ET, the combination of plant and ground surface transpiration and evaporation) forms an important part of the water balance and few ET models have been tested with Miscanthus. Therefore this study uses field measurements to determine the most accurate ET model and to establish the interception of precipitation by the canopy (Ci). Daily ET estimates from 2012 to 2016 using the Hargreaves-Samani, Priestley-Taylor, Granger-Gray and Penman-Monteith (short grass) models were calculated using data from a weather station situated in a 6 ha Miscanthus crop. Results from these models were compared to data from on-site eddy covariance (EC) instrumentation to determine accuracy and calculate the crop coefficient (Kc) model parameter. Ci was measured from June 2016 to March 2017 using stem-flow and through-flow gauges within the crop and rain gauges outside the crop. The closest estimated ET to the EC data was the Penman-Monteith (short grass) model. The Kc values proposed are 0.63 for the early season (March and April), 0.85 for the main growing season (May to September), 1.57 for the late growing season (October and November), and 1.12 over the winter (December to February). These more accurate Kc values will enable better ET estimates with the use of the Penman-Monteith (short grass) model improving estimates of potential yields and hydrological impacts of land use change. Ci was 24 % and remained high during the autumn and winter thereby sustaining significant levels of canopy evaporation and suggesting benefits for winter flood mitigation.publishersversionPeer reviewe

EFSA Panel on Biological Hazards (BIOHAZ); Scientific Opinion on public health risks represented by certain composite products containing food of animal origin

This Opinion reviews the factors that affect microbial survival and growth in composite products, and in foods in general. It concludes that the main factors to be considered are: water activity, pH, temperature and duration of storage, processing, and intensity and duration of other non-thermal physical processes applied. Prevalence and concentration of the pathogens in food are important to determine the risk for consumers. The opinion presents a review of the quantitative microbiology models and databases that can be used to provide quantitative estimations of the impact of the above factors on the survival and growth of the main bacterial pathogens. In composite products, migration and diffusion of moisture and substances among the ingredients may change their physico-chemical parameters, particularly at the interfaces. Therefore, the assessment of the risk posed by composite products needs to consider the combinations of parameters most permissive to survival and growth of pathogens. Two complementary approaches are proposed for the identification and profiling of microbiological hazards in different specific composite products. The first one is based on past outbreaks and prevalence of hazards in the products and leads to the conclusion that the most frequent hazard-composite product combinations are Salmonella in cakes and bakery products. The second one consists in decision tools based on the impact on the pathogens of food composition and food processing. Categorisation of the risk for composite products requires information on their composition, processing and further handling, which can largely differ for foods belonging to the same category. Further conditions may influence the risk and should be verified, i.e. hygienic conditions during preparation of the composite products and their ingredients, shelf-life conditions, and reliability of cooking by consumers to inactivate pathogens. The decision tools developed apply to all composite products considered by the mandate, as well as to all other foods. © European Food Safety Authority, 201
