ABSTRACT In the consumer phase of a typical quantitative microbiological risk assessment (QMRA), mathematical equations identify data gaps. To acquire useful data we designed a food consumption and food handling survey (2,226 respondents) for QMRA applications that is especially aimed at obtaining quantitative data. For a broad spectrum of food products, the survey covered the following topics: processing status at retail, consumer storage, preparation, and consumption. Questions were designed to facilitate distribution fitting. In the statistical analysis, special attention was given to the selection of the most adequate distribution to describe the data. Bootstrap procedures were used to describe uncertainty. The final result was a coherent quantitative consumer phase food survey and parameter estimates for food handling and consumption practices in The Netherlands, including variation over individuals and uncertainty estimates.

This study examines the influence of social network members (versus strangers) on sustainable food consumption choices to investigate how social influence can challenge the status quo in unsustainable consumption practices. We hypothesized that changes to individual consumption practices could be achieved by revealing ‘invisible’ descriptive and injunctive social norms. We further hypothesized that it matters who reveals these norms, meaning that social network members expressing their norms will have a stronger influence on other’s consumption choices than if these norms are expressed by strangers. We tested these hypotheses in a field experiment (N = 134), where participants discussed previous sustainable food consumption (revealing descriptive norms) and its importance (revealing injunctive norms) with either a stranger or social network member. We measured actual sustainable food consumption through the extent to which participants chose organic over non-organic consumables during the debrief. Findings showed that revealed injunctive norms significantly influenced food consumption, more so than revealed descriptive norms. We also found that this influence was stronger for social network members compared to strangers. Implications and further research directions in relation to how social networks can be used to evoke sustainable social change are discussed.

Food production is associated with various environmental impacts and the production of meat is highlighted as a significant source of greenhouse gas emissions. A transition toward plant-based and low-meat diets has thus been emphasised as an important contribution to reducing climate change. By combining results from a consumer survey, focus group interviews and an in-store field experiment, this article investigates whether Norwegian consumers are ready to make food choices based on what is environmentally sustainable. We ask how consumers perceive the environmental impacts of food consumption, whether they are willing and able to change their food consumption in a more climate-friendly direction, and what influences their perceptions and positions. The results show that there is uncertainty among consumers regarding what constitutes climate- or environmentally friendly food choices and that few consumers are motivated to change their food consumption patterns for climate- or environmental reasons. Consumers’ support to initiatives, such as eating less meat and increasing the prices of meat, are partly determined by the consumers’ existing value orientation and their existing consumption practices. Finally, we find that although providing information about the climate benefits of eating less meat has an effect on vegetable purchases, this does not seem to mobilise consumer action any more than the provision of information about the health benefits of eating less meat does. The article concludes that environmental policies aiming to transfer part of the responsibility for reducing greenhouse gas emissions to food consumers is being challenged by the fact that most consumers are still not ready to make food choices based on what is best for the climate or environment.

Study was conducted during spring and autumn season (2018 & 2019) to screen and identify rich nutrigenetic breeds from the selected breed’s for their nutrigenetic traits in silkworm, BombyxmoriL.(Lepidoptera: Bombycidae) is an essential prerequisite for better understanding and development of nutritionally efficient breeds under Subtropical condition of Jammu based on the breeds which shows less food consumption with higher efficiency conversion based on leaf to cocoon and leaf to shell ratio. Highly significant variations were found among all nutrigenetic traits of bivoltine silkworm breeds in the study. The nutritionally efficient silkworm breeds were shortlisted by utilizing nutrition consumption index and efficiency for conversion of ingesta/cocoon traits as the index for selection of highly promising breeds. Furthermore, based on the average of data from both the seasons, the overall rearing nutrigenetic traits utilized as index, eight bivoltine silkworm breeds (B.con 1, B.con 4, BHR 2, ATR 16, BHR 3, CSR 50, RSJ 14 and NB4D2) were identified as havingthe potential for nutrition efficiency conversion and can be utilized for further breeding programme. The data from the present study advances our knowledge for the development of nutritionally efficient silkworm breeds/hybrids and their effective commercial utilization in the sericulture industry.

Abstract The paper describes the selection of a distributed propulsion for the AOS H2 motor glider (selection of engines, their number, and propellers) and determination of its performance. This analysis is related to the research conducted on environment friendly and hybrid propulsions in various research centres. The main aim of the analyses conducted is to increase the performance of vehicles powered by electric motors. The batteries have a low density of energy, i.e. the ratio of mass to cumulated energy. Instead of a battery set, it is possible to apply a hybrid-electric system, where the combustion engine works as a generator or an electric-hydrogen generator, where the hydrogen cell supports a small set of batteries. One of such flying vehicles, fitting in this trend, is the AOS H2 motor glider built at the Rzeszow University of Technology in cooperation with other universities. It is a hybrid aircraft, equipped with a hydrogen cell, which together with a set of batteries is a source of electricity for the Emrax 268 electric motor. To increase the vehicle's performance (the range and flight duration), it is possible to use a distributed propulsion. This type of propulsion consists in placing many electric motors along the wingspan of the aircraft. Appropriate design of such a system (propeller diameters, engine power, number of engines) can improve the aerodynamic and performance parameters of the airframe. An analysis of the performance for the selected flight trajectory for this propulsion variant was conducted and compared to the performance of the AOS H2 motor glider equipped with traditional propulsion. The consumption of hydrogen was also determined for both systems. The results obtained were presented in the diagrams and discussed in the conclusions.

The distribution of the intensity of the comet Ison C/2013 is studied by taking its histogram. This distribution reveals four distinct regions that related to the background, tail, coma and nucleus. One dimensional temperature distribution fitting is achieved by using two mathematical equations that related to the coordinate of the center of the comet. The quiver plot of the gradient of the comet shows very clearly that arrows headed towards the maximum intensity of the comet.

Sustainable consumption practices help to reduce environmental impacts and fosters responsible consumers. Researchers have explored the positive drivers and negative barriers of fashion-conscious consumer (FCC) purchasing intention on fashion clothing. The study also examined the motives and outcomes of the phenomenon, such as rental landscape and frugality. Using the qualitative phenomenological method, researchers conducted 21 in-depth semi-structured interviews in India to tap into FCC's buying intention and experience. From the results of qualitative analysis, researchers identified “emotion” as a new parameter reflecting consumer passion and interpersonal relationships. Different themes emerged, such as selection of the style, attention-seeking, status value, cost factor (uncontrollable), and psychological value, which are the commonly identified motivators. Conceptual framework is developed to understand the perception towards green environment and sustainability. The implications are to improve the sustainable practices in the fashion sector through rental options and frugality.

Although survey results measuring the safety of consumers' food handling and risky food consumption practices have been published for over 20 years, evaluation of trends is impossible because the designs of published studies are not comparable. The Food Safety Surveys used comparable methods to interview U.S. adults by telephone in 1988, 1993, 2001, 2006, and 2010 about food handling (i.e., cross-contamination prevention) and risky consumption practices (eating raw or undercooked foods from animals) and perceived risk from foodborne illness. Sample sizes ranged from 1,620 to 4,547. Responses were analyzed descriptively, and four indices measuring meat, chicken, and egg cross-contamination, fish cross-contamination, risky consumption, and risk perceptions were analyzed using generalized linear models. The extent of media coverage of food safety issues was also examined. We found a substantial improvement in food handling and consumption practices and an increase in perceived risk from foodborne illness between 1993 and 1998. All indices were stable or declined between 1998 and 2006. Between 2006 and 2010, the two safe food handling practice indices increased significantly, but risk perceptions did not change, and safe consumption declined. Women had safer food handling and consumption practices than men. The oldest and youngest respondents and those with the highest education had the least safe food handling behaviors. Changes in safety of practices over the survey years are consistent with the change in the number of media stories about food safety in the periods between surveys. This finding suggests that increased media attention to food safety issues may raise awareness of food safety hazards and increase vigilance in food handling by consumers.
